Re: MI-L MB Text file editing
Jens Åge Nielsen wrote: I want MapBasic to read an ASCII text file and search for a particular text string. If the string is found, it should be replaced by another string. The new string may be shorter or longer than the original one. The text file is sequential, not fixed-length. There's more than one way to do this, but here's a possible solution, assuming the following conditions are true. 1. Your ASCII file contains individual lines of text, each line terminated by a newline or carriage return character. 2. No line of text in your file is longer than 255 characters. If these conditions are met, then open the text file for input and use "line input" to read in each line. Open another for output. Then read each character in the string, looking for the first one that matches the first character in your target string. If you find a match, keep track of the position in the string where it, and copy the searched string up to that point to the output file. Check the next characters to see if you really have found your string. If any character is found that indicates that you haven't got the full search substring, then copy everything from where you first started checking up to the current point, and continue on. If you do find your search string then simply copy the replacement string to the output file instead, and proceed as before from where your search string ends. Do this line by line until the file is done, then close both files, use "kill" to delete the original and "rename" to change the new output file name to the original file name and you're done. An obvious wrinkle in this algorithm is what happens if the search string spans more than one line? If you are finding matches for your search string, and you run out of line, then read another line and tack it on to the first, and continue searching as you had been. You might want to stick a newline (chr$(10)) in your output to sort of maintain line wrapping but that's up to you. Actually, line wrapping is really a separate function with its own bucket of worms to sort out. This is probably not the most efficient technique, but it's easy, and it will work. A character by character file search in MB is slow. You might speed it up by breaking out words instead of characters with InStr() by searching for spaces as delimiters, and then doing word string comparisons instead of character comparisons. Actually, search and replace is a fairly knotty problem when you really get into it, but it's an interesting problem. If you want some real fun, try to build an editor in mapbasic. One that supported RTF and HTML might be quite a handy tool, but I think if you try this with MapBasic, you would find the job to be something like building the Three Gorges Dam with a teaspoon. - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet ___ List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MapInfo-L" in the message body.
Re: MI-L Newbie Question
Eddie wrote: I'm new to MapInfo and have a very basic question that I can't seem to find the answer to. The salesperson who sold it to me 'promised' to set up the first several maps that I needed. That was just before the sale however. Now she's non-existent. The question is: How do I layer the thematic maps so that they are transparent. I have 5 layers on one map and need to be able to see all of the layers. I have all of the layers setup and in use but can only see the top layer. I've used patterns to distinguish each layer if I can only view them. I know that I can send each layer up or down but still have the same problem viewing ALL of the layers. You need to use the "transparent" styles for the themes on top, and the odd thing is that you need a separate master layer between each (which you must make invisible to see through it) I did make it work with the States table. Basically open the table in a mapper, and create your first theme. Then add a second copy of the layer to the map, and them that. Be sure to choose only one of the "transparent" pattern themes, and make sure each theme is above a separate copy of the map layers (use Layer Control to see). Finally, turn off the visibility on all master layers between the themes (answering "No" to question it asks you. This will work, but what won't work is trying to add a second theme to a layer that already has one; even if you choose a transparent pattern. Each theme must be based on a separate layer, but you can use multiple copies of that layer. -- - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet ___ List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MapInfo-L" in the message body.

MI MapInfo-L moving news
Thanks for all the feedback folks! Im really a bit overwhelmed at all your positive response and all the personal offers to help support MapInfo-L with actual cash and resources. Were actually in no danger of ending up begging on the street it seems. I think to start with we will keep any advertising pretty light. It doesnt take much to keep us going but its not nothing, either. So you may or may not see an ad in the future occasionally. If these do appear, they will be as short and pithy as possible (40 words max), focused on MapInfo-related interests, and Ill try to make sure you dont get too much spam in your email diet. You can sing the Monty Python Viking Song at me if it ever gets too much up your nose. (1200-part harmony should be pretty interesting!) Okay, enough philosophy; heres the deal. On Wednesday, Sept 27, Jeff Koncz (Direction Magazines web wizard) and I will transfer all the current subscribers from the old list to the new. This will take a little time to do so messages will probably still be flowing over both lists for a while. We may mess up a thing or two so give us a day or so to sort it out before you scream bloody murder. You can also unsubscribe yourself from the old list, and sign yourself up to the new anytime now if you like. Heres how: To sign up to the new list, send email to [EMAIL PROTECTED] and in the body of the message, just put: subscribe MapInfo-L and that will do it. To send public mail to the new list, the address is [EMAIL PROTECTED] You can start sending mail there as soon as you are signed up. The old list will be closed after Oct 6th. Maybe mail will get forwarded, but things may be melting down pretty quickly over at Supernet then, so I wouldnt get stuck there if I were you. If you dont remember how to get off the old list, just send mail to [EMAIL PROTECTED] and in the body of the message put: unsubscribe MapInfo-L BTW, spelling counts (but type-case doesnt). "uscriv", "unsusbribe" and other random associations of letters will get you null results. Remember youre giving commands to a robot, and its a pinhead. Like any computer, it will do exactly what you tell it to do... which is why computers can be so frustrating at times. Whether you wait to be transferred automatically, or do it yourself, you will receive a "Welcome" message that will tell you all about MapInfo-L and how to use the Directions Magazine majordomo mailing list software. If you dont get a welcome message by Friday, the transporter beam failed, and all your atoms are scattered hither an yon throughout cyberspace. Bummer.

Advertising to fund MapInfo-L (was MI ANNOUNCEMENT: MapInfo-L is moving! -No Advertising!!)
[EMAIL PROTECTED] wrote: One Comment about the advertising with the e-mail. Don't do it! That's the sort of thing that could run me off from this list faster then any thing else. Would you be willing to pay a subscription fee to get the list mail then? How do you suggest we afford the service? Would you prefer twice-yearly fund drives like they do for public broadcasting? It's been free because I managed to get a good deal at Colorado Supernet for the last 6 years. That made it cost so little (and was helped by some donations and the proceeds of an auction) that my business carried it these last few years. It cost $14.95/mo plus my time, which was gladly given because it has also been good for my business. But SuperNet got bought out by Qwest/US West, and because SuperNet isn't profitable enough for the big wheels, the wheels are closing down that service. The hard, cold Morlocks meet the Eloi of the Internet. In a perfect world advertising serves to connect people who have needs to products and services that answer those needs, and that's the goal we would try to attain. I am all too aware that in our real world, advertising also tries to *create* needs and wants and stick a straw into your wallet and suck hard. We all know that activity sucks, but is there any creative solution that we can come up with where we can generate enough cash to pay for the infrastructure we need to make this list a success? Lists do not live by email alone. Perhaps we can do a mix of paid subscriptions with no advertising with some freebie subscriptions that come with a helping thinly sliced spam. How about the USGS buying up a block and giving them out to employees? Maybe people with deeper pockets could fund subscriptions for students who are full of bright ideas, but no money. Maybe we could charge enough for advertising so that there wouldn't be many (but if there were none, that wouldn't help) Or maybe the ads wouldn't be so bad or common anyway. Maybe we could do a mix of donations, light advertising, auctions, and fund drives. But all that work takes volunteers or paid staff. Advertising is the easiest solution. If you don't want it at all, get creative, and not to put too fine a point on it, put your money where your mouth is. The form that these will take has not been decided yet anyway. All that's been talked about is that the service can be offered and that advertising would be a covenant way to afford it. As Henry D. Thoreau once said, "All great enterprises should be self-supporting."

MI ANNOUNCEMENT: MapInfo-L is moving!
As a result of all the recent telecom mergers here in Denver recently, the service provider we have been using to host MapInfo-L is getting its plug pulled Oct 6 and we have to move the list. The domains csn.net and sni.net will be cold and dark after the 6th. The new home is going to be at Directions Magazine very shortly. We will be running a more up-to-date majordomo server so we will finally have digest capability, faster turnaround and some other goodies. The rules and guidelines aren't going to change and Scott Elliot (owner and publisher of Directions Magazine) has assured me that your email addressed will not be used for any other purpose than the MapInfo-L subscriber list. I'll still be doing the caretaker services, and my address here isn't going to change. You will still be able to receive individual emails, but now digest mail will be available. You will also be able to read mail in the Discussions area on Directions Magazine's web site. Things will work basically like they do now, only faster and there will be more features. Another change is that there will some MapInfo-oriented advertising in the new email, but the form this will take is not yet decided. We need to figure out a way to make it all worth everyone's while. Ideas or suggestions anyone? Your email addresses will be moved automatically in a few days, so all you'll have to do is change where you send messages. You'll also all be sent a new "Welcome" message that has all the details and commands for working with majordomo in it. If you don't want to have your address moved automatically, then you should unsubscribe before addresses are moved. I will let you know a few days when addresses will be moved. I'll announce the new server and list addresses real soon now after we finish testing. This note is just a "heads up" to open up the discussion and give people time to make any changes they want to make.

MI FYI MapBasic Developers: A Tool for Building MB Dialog Code
Remember a few weeks ago when DiaBuilder was first announced in this forum? This is a software tool used for building MapBasic dialog code visually. For me, writing MapBasic dialog code is pretty much an ordeal and it takes far too much time. I needed something that would speed up this process, and figured that risking $40 was no big deal, so I bought it. Besides, it's built by an active MapInfo-L member (Trey Pattillo), and I've learned that you can sometimes find some pretty amazing software inventions in this group! Well by golly, it works, and it works very well! It *is* a real find. I liked it enough that I thought it was worth reviewing to let other developers know about this, so if you're interested, click on over to Directions Magazine and you can read about its pros and cons: http://www.directionsmag.com/article.asp?ArticleID=76 There is a free demo of DiaBuilder available from http://www.wap3.com/diabuilder2000.htm, but if you have to write more than 2 or 3 real MB dialogs a year, I think you will find that the commercial version pays for itself very quickly. - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

Phriday Philosophy (was: MI and Manifold)
In reference to the short discussion on whether Manifold is as good as they say: "Eric Frost / HR and Associates, Inc." wrote: Note: this sort of disturbs me (and still I like it) that we discuss other GIS's and any topic actually on this MI-list... I just know arcview-l is moderated--they've turned down a few of my innocuous queries about intl data--but to add to the discussion regarding MI's marketing (I noticed several posts regarding their education sector efforts) couldn't MI pony up to allow BT or anyone to sift through stuff? at least we would not be a prime deliver of KAK...(pun intended) As everybody here knows, MapInfo-L is a very open forum--some would say it's too open, but I kind of like that aspect too. To my mind, the horizon of my the GIS sphere doesn't end with MapInfo, and learning of a few seemingly unrelated things seems to broaden my view. However, MapInfo-L isn't GIS-L or GISlist, and perhaps we need to remind ourselves occasionally that it's main focus is MapInfo. General GIS comments or questions probably ought to go to those other lists first. I'd prefer to leave that as a guideline rather than a rule, because I wouldn't want to be a censor, or suffer anyone else's permission to post whatever I'd like to post. Sometimes a serendipitous posting generates a very welcome but unexpected line of thought. Of course, a nicer and more positive term for censor would be "editor." An editor would ensure that what makes it into the email stream would be clean (no virus or spam) mail, summarized responses, HTML format-free and attachment-stripped messages. The topics would be limited to what that edited forum lists as relevant. Anyone could post to the forum too, but whether their message just passes through to the origin forum(s), or gets rejected, or gets included in the edited feed depends on how closely they follow the forum's guidelines. Think of it as a managed portfolio of email. One focus might be MapInfo-not-Programming, or another might be MapInfo-with-significant-GIS-events. Still another might be MapInfo-and-competition-wireless, or something like that.

Re: MI New Company
Toby Walker wrote: Hey list, I've been looking at a new company that deems themselves SIM guys. Im not sure what this paradigm is, but the Company is called TerraGraphics. I checked out their web site by fluke this morning, and I wanted to see what other GIScientests thought about this.. Well, the term "GIS" never did cut in the business world, and the Canadians (who invented the discipline) dropped it in favor of "Geomatics" as soon they realized that the Usonians (US Americans) decided that it was cool and appropriated it. And now, "Spatial Information Management," or SIM, appears in a web page with phrases like "Convergent Technology," "Amplified Mapping at Terminal Velocity," "market share," "competitive advantage," "businesss intelligence" and a great deal of additional hyperbolic buzzword twaddle. I see no "science" here (other than transparent propaganda.) But give them credit, sometimes a new name is all that's required to sell a well-known technology. Perhaps there's some science there in the background, but the web page tells us only that they have a geek in residence (GIR), and that he's just amazed the marketing staff with his brilliance. (well of course... GIS, like any other suffciently advanced technology, is indistinguishable from magic to hoi polloi.) But I saw no examples of anything concrete; just colorful words. Good job there though. Inspiring rhetoric with no visibles means of support. That sort of thing is yet another kind of magic. This web page makes my thaumometer pratically go off the scale. But where's the science? Finally, this line bothered me, especially on top of so much vacuousness. From their web page: "At a time when Geographic Information Systems and Information Technology are converging into a new business discipline called Spatial Information Management, one company plans the complete infiltration and exploitation of geography in the business marketplaceTerraGraphics..." "...complete infiltration and exploitation of geography..." "...complete infiltration and exploitation of geography..." "...complete infiltration and exploitation of geography..."

Re: MI License plates addresses
Ken Fioretti wrote: I have a retail client who approched me with this problem: They want to convert the license plate numbers of their customers into addresses for tracking purposes. My first question is, how can I get this done? Any help would be most appreciated. I would also like to hear from anyone wishing to address the legal, ethical, moral, or privacy issues. States have been known to sell drivers license info with SSI #, address and picture if the price is right (I think it cost $5000 for all of Colorado at one time), but I suppose for car tags the agency you'd contact would be the state DMV. On the ethics side of things, I think that all citizens who cannot opt-out of license plates or drivers licenses by law if they want to drive, ought to be able to require any other party to ask permission of them FIRST before they use these public records for purposes beyond what they were originally intended for. My first question is WHY do you want to get this done? I know, the short answer is because the client is willing to pay for it... but that's not my point. Perhaps as GIS experts, and keepers of the keys so to speak, we should start considering our role in developing the information terrain of tomorrow's landscape. We do have some control over now. Where's the limit for personal privacy? Consider all the interesting things we could do with GIS if we could only get everyone from new-born babies to most experienced in living fitted with lifetime subcutaneous transponders that would broadcast their unique Id when scanned. You'd never lose track of yuor kids again. In a disaster, emergency response teams could find you anywhere. Crime and mayhem would drop to zero, because criminals couldn't hide. Market analysis would be so much more efficient and less costly, and the governement (or anyone) could run an accurate census every day. Tie all that realtime micro-spatial accuracy to powerful data harvests from electronic transactions and you'd have a dream world! Dream world? I'd call it a nightmare. Even Machaevelli would probably have misgivings. But if you think that's too much, then where DO we draw the line? A question all engineers should ask themselves every once in a while is, "Do I accept any job because it has interesting challenges or pays well, or are there some things I won't do on principle?"

Re: MI Global Variable
I think the problem is that you have to include "header.def" in all your modules. At least you have to declare 'global iWinIdMap as Integer' in every module where you will use it. That said, you also cannot declare that same variable anywhere else because a more local declaration will take precedence oover yuor global definition. In other words, if you define a global variable in a module, and then declare a local variable in a sub in that same module, then when your program flow enters that sub, it will use the local variable instead of the global. Daniel Budmiger wrote: i want to use the same variable in different project files. as i know this should be possible with the global variables. in my program this does not work. the declaration of my subs and the declaration of my variables are stored in a special header.def - there is also the code: global iWinIdMap As Integer. In the main sub this variable gets the integer value of a special map-window. if i show this id from another sub in another project this variable does not have the same content. has anybody a good idea for a solution or what i am doing wrong? - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

MI The Diabolical MapInfo Exam
Tim Rood wrote: We may well be able to create the diabolical MI test. For years we've stumped MI developers with "tests" of improved functionality. I'm a little out of date on the wish list but where's the "not in" query, just for example? or the "switch selections" a la AV? I promise to contribute a devil of a question in the "Intermediate Mapper" category, if we can get others to join in. Okay, you're on! I have a couple in mind too. Anyone else have a doozy of a question gauranteed to make a MapInfo wizard weep and wail? All we need is twenty questions; multiple guess (please supply the right answer too; we don't want to out-diabolicalize ourselves, okay?) At least one MapInfo employee has dared to take on any challenge we can come up with. Assuming, of course, that we are up to it. I'd suggest that these questions be like MapInfo's test, only harder (this is for those who think they know their stuff, y'know.) They should involve only what's in the MapInfo Users Guide or Reference Guide and what can be done with the user interface (i.e. no mapbasic questions that aren't already covered in the chapter on the MapBasic Window, but that still leaves a lot of open ground...) The best questions would be those that concern typically common user problems (like what happens when you open a workspace with custom labels after you've packed a table, or problems of setting scale, fonts, etc.) I think that we could have questions with more than one correct answer, but at least one of those answers has to cover all the other correct answers. (Questions with NO right answer are okay too, providing "none of the above" is a answer choice!) There can also be terms used (like geocoding and geo-referenceing) where the correct answer is in the MapInfo lexicon, while the other is not (perhaps you might throw in an ArcView term that matches a MapInfo one to stump the poly-GIS phonic.) I'll be happy to collect questions, and then pass them out to contributors to vote on the Final Twenty, and then maybe we can get them set up on a Directions Magazine web page so people can take the Challenge. As to results, I'd suggest that the individual results should be anonymous, and the test would be open to all. But I'd like to see a summary of past results so a person can see how they did compared to others, and the world can see if the questions are truly diabolical or a breeze. Perhaps there are some university profs out there who know a thing or two about making tests. I'm just throwing out some ideas; professional advice would be welcome!

However, as long as you don't use any 6.0 features, all you have to do to get your mbx to run in an older version is edit the very top line of the mbx and replace the 600 with 550 or 500 or whatever your MI version is. You need to edit this with a hex editor, because a text editor will make a mess of the binary contents of an mbx. If you want to take a trip into the WayBack machine, you can do this with that venerable and most spartan microsoft software you will porbably ever see. It's called debug.exe (it's in c:\Windows\Command\ on Windows machines). This is the tool that Real Programmers use to build Windows programs (muhaha!) Anyway, picture yourself back in 1988. Open a DOS window and change directories to where your mbx is. Hmmm... okay, I see we've lost a few already. The old DOS command to change directories is "cd" followed by a space and the name of the directory on the same line. Then type in "debug" followed by a space and the name of your mbx. Now your prompt turns into a simple dash. This "command line" stuff is what we used before they invented the user interface. You could almost see a Zen koan in something so simple and yet at the same time so opaque. This is a super-powerful tool too, so don't just press buttons willy-nilly!

Try it with NViews.mbx in c:\Program Files\MapInfo\Professional\TOOLS\ At the DOS prompt, type Debug Nviews.mbx At the debug dash prompt type "d" (for 'Dump') This "dumps" the hexadecimal and ASCII equivalent of your mbx to the screen. Notice over on the right you can see the 600 version number. To edit is, type e 010E and press enter. (e stands for edit, and the position to edit is offset 10e, where the h36 is or '6' in ASCII.) Now you see 36. Enter the hexadecimal number that you want in place of 36. The character '5' is 35. Press a space to edit the next byte, which is 30. Change it to 35. Press Enter to exit edit mode. Now the dump the data again to see your changes. The command is d 100 (dump the next paragraph from offset H100) See? Now the version number is 550, or MI version 5.5. Now save the file back to disk with the 'w' command (Write). then to quit, enter 'q'. If you ever want to see debug's help, enter '?' at the dash.

If the user opens or previews an infected email message the worm drops KAK.HTA program into Windows startup folder so that it runs on starting Windows. The KAK.HTA file creates C:\WINDOWS\KAK.HTM hidden file and changes the Microsoft Outlook Express registry settings so that the KAK.HTM is automatically included in every outgoing message as a signature file. KAK.HTA also changes the Windows registry key HKLM\Software\Microsoft\Windows\CurrentVersion\Run\cAg0u so that it includes the name of the worm file.

Is there a way to prevent this, and have the program1 running in the background and processing its DDE messages when there's a mapinfo dialog in progress? The only way I know to do this is to intercept all program requests to menus or dialogs and before passing them on to the actual routine (via run menu command or similar) issue a 'Set Handler RemoteMsgHandler off' This disable the RMH, and the DDE messages arriving in the meantime are lost. However, it does get rid of Before returning control, turn the handler back on. Writing the code to intercept all MapInfo controls is pretty tedious, too, but you can rewrite all the menus to pass through your own routines first if you need them to. Also this technique throws the DDE messages away. If that's not acceptable, then maybe your intercept code should also tell your VB app to do something else with the messages until your MB app is free again. - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

Module scope globals are almost required for any MapBasic dialog beyond the trivial. For those, I just create a separate module for the dialog, and then use 'dim' to define globals I need. That way there's little chance that a global there can foul some other part of the application. Defining variables as 'global' instead of 'dim' at the module level is what I'd call uncontrolled, and should only be done if you want to live in interesting times. Besides, anyone who programs in MapBasic already has to compromise his or her sense of purity to a certain extent. In a language where there are no function-level static variables and NO private functions anywhere, you can only be so holy about it. Especially when it comes to dealing with MapBasic dialog structures. Your global array is easily a module-scoped variable, and the use you make of it is clever, obvious and totally appropriate.

Re: MI Lack of mail!!
Simon W Fox wrote: I haven't received anything from the list for a couple of days. Is everything OK or is there a problem? You probably got unsubscribed if your mail server started refusing MapInfo-L messages. Lately, this is usually the result of misguided anti-spam and virus countermeasures employed by your ISP. Some of them blindly block all mail that is relayed to you via a mail server (like ours at [EMAIL PROTECTED]). The theory is that if the original sender is not the current sender (i.e. someone sends mail to the list as the original sender, and the list sends that message to everyone else becoming the relaying sender) then the mail must be unwanted trash. Of course, that's not always true, so clear that up with your ISP. Other reasons for mail being bounced include people abandoning their accounts, letting their disk quota get exceeded, misconfigered servers, broken down servers, and probably a few evil spirits drifting about the net. True, sometimes these problems are temporary, but when I see that messages could not be sent to your server for more than a couple of days, I don't want to deal with several more days of bouncing MapInfo-L mail coming from your server, so your address gets lopped off the subscribers list. Since tens to hundreds of bounced messages from the list pile up in my mailbox every day I've been getting more aggressive with taking problem addresses off the list. I can't always send you a note about it because that takes a lot of time (and if your address is broken it won't reach you anyway), but if I don't keep the broken addresses cleaned up, then the list delivery slows down as the MapInfo-L server tries to resend messages or wait for timeouts. Until we get a more automated setup (I'm considering moving the list to the Directions Magazine list host... so give that some thought) I'll be dropping any addresses causing more than their fair share of trouble. Anyway, the solution is to resubscribe. If your address continues to be a problem, I'll start to notice and will contact you (because by resubscribing I know you really are still out there) and we will work it out. - Bill Thoen -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

Re: MI Friday History
IMHO, Paul Thurrott's piece is just another part of Microsoft's propaganda campaign. It is an interesting example of how to twist history though. Not entirely "the way it was," either. For example, far from there being all this serious CP/M competition back then, it was IBM's market dominance and the fact that the IBM PC shipped with PC-DOS (IBM's brand of MS-DOS) on board that gave Microsoft their big break. The others didn't really have a chance. True, MS had their share of blind luck (especially when IBM handed this monkey the keys to the banana plantation--note this is how you get 500-lb gorrillas), and it's also true that Gates was shrewd enough to take advantage of opportunities (lots of competitors then didn't see what seems so obvious now, and now they are forgotten history.) Even though competitors made mistakes, competing directly against an agressive monopoly like Microsoft is like playing snakes and ladders... with greased rungs. Mistakes come easier that way. What bugs me about this article is that it tries to paint Microsoft as some sort of Horatio Alger--poor but honest, one against long odds, excuse us, but it's just everyone else just keeps falling on their swords...

Re: MI Frames ID
It's better to create the layout each time, unless you can identify the frames by their row number, size or position. A layout behaves like a table without attributes. You get the table name with the WindowInfo() function, and each object has a row position and a type, which can be examined with ObjectInfo(), etc. Unfortunately, there is no FrameInfo() function, and that's a pity, because that means you can't examine attributes specifically associated with frames.

Re: Meaning of MI Parameters
Clifford,
I'm certainly no expert on Geodesy, but I think you didn't get
all the parameters from whoever asked you for help. Seems to me
that all the factors you claim are missing are, in fact, in the
MapInfo projection file. Perhaps a scale factor of zero is what
you mean by a missing (or at least "truncated") value, but it
*is* there.
Adding comments to the the Luxembourg (Bursa-Wolf) parameters
record listed in mapinfow.prj (see appendix H and I in the latest
MapInfo User's Guide) I see:
"LuxGrid (Bursa-Wolf)",
8, {projection 8 = Transverse Mercator/Gauss Kruger}
,{means "custom datum"}
4, {ellipsoid: 4=International 1924, a=6378388.0,
1/f=297.0}
-185.836,{shift dX, in meters}
13.479, {shift dY, in meters}
-14.527, {shift dZ, in meters}
0.441203,{rotation Ex, in arc-seconds}
3.027399,{rotation Ey, in arc-seconds}
-2.607685, {rotation Ez, in arc-seconds}
0, {scale correction factor m, in parts per 10^6}
0, {longitude of prime meridian}
7, {units 7 = meters}
6.16667, {origin Longitude}
49.8333, {origin Latitude}
1, {scale factor}
8, {false easting}
10 {false northing}
The MI book doesn't say what in which order the scaling, rotation
and translation are done, but I assume the order for performing
the transform is scale, rotate and then translate since these
ellipsoids have a common center.
According to the manual, the "Simplified Bursa Wolf" is
"truncated" because that particular transform assumes that only
an ellipsoid and shift parameters are needed.
So what should the scale factor be for Luxembourg (Bursa-Wolf)
transformation? And are the parameters for the "International
1924" datum the same as the "European Datum 1950" you cite below?
If not, I need to correct my settings. Also to satisfy my
curiosity, I'd like to try out a couple of coordinate transforms
using MapInfo's parameter file (set up properly) against whatever
you use to see how "grossly inaccurate" MapInfo is. I'm not
convinced that "computer jockeys" are entirely ignorant
knowlessmen.

Luxembourg, and it is rather complicated. Bursa-Wolf is the name of a
mathematical model for performing transformations from one specific Datum
to another specific Datum. In this case, it refers to the transformation
from European Datum 1950 to the World Geodetic System 1984 (WGS84) used by
GPS satellites. The parameters are in meters and are earth-centered in
the Geocentric Coordinate System and refer to a dX,dY,dZ translation at the
center of the earth AFTER a three-parameter rotation RZ,Ry,Rx (in radians
or arc seconds) and an overall scalar (dimensionless) multiplication is
performed FIRST.
What is remarkable is that the "MI example file" is grossly incorrect!
That is indicated by the fact that only six of the seven parameters for a
Bursa-Wolf Transformation are given, (the Scale Factor is not even given),
and for the "(Simplified Bursa-Wolf)" it is an obvious truncation!!
This example file is an excellent lesson of what happens when programmers
and mathematicians try to play with Geodesy - they obtain the usual result;
a complete screw-up! Apparently unknown to some "computer jockeys," the
solution for the seven parameters of a Bursa-Wolf model or a
Molodensky-Basdekas model always involves a solution for the rotations and
the scalar FIRST - THEN the translation parameters are solved. That means
that the rotation parameters (and scale factor) may NEVER BE TRUNCATED!!!
To the neophyte (read "computer jock"), the rotation angles look so small
that they appear to be insignificant. However to one that works with the
math of the actual parameter solutions, one knows that the tiny rotations
are at the center of the earth! When you examine the effect at the surface
of the ellipsoid - the magnitude is quite substantial! Same thing goes for
the scale factor expressed as so many parts per million. Tiny numbers with
negative exponents, but when you consider the semi-major axis is
6,378+ kilometers; the effect is again quite substantial! Transformations
are affected by such blunders and resultant data will be grossly incorrect.
Therefore, in the "example MapInfo file for simplified Bursa-Wolf
parameters," the only thing simple is the simpleton that truncated the
critical parameters!
In regard to your local problem of implementing such data for your country,
I shall be happy to assist you in determining the appropriate parameters if
you send your data to me via e-mail. I will then solve for a 3-parameter
model, a 4-parameter model, and a 7-parameter model and provide you

MI MapBasic project estimation and planning
I have found that most small mapbasic projects are fairly easy to plan and estimate, but that the larger ones are sometimes a *lot* more difficult. I'm not sure how much of this is due to the lack of software management tools available for mapbasic, and how much of this is just the usual problems endemic in software planning, but I need to find some better techniques or tools. Sometimes I find that the first hurdle is finding out what the client really wants. The problem is that they often don't know what's possible, or how to describe what they only vaguely have in mind. When that happens, your estimate and schedule is already in danger. Other times I under-estimate the true complexity of the user interface, and a simple dialog box gets up off the slab and turns into a lurching, moaning, multi-page monster. For example, user-defined picklists can be a danger signal; they're not a trivial edit control. Dialogs that link data from more than one table also can get complicated, too. How do you estimate the depth of these pitfalls (short of diving in headfirst and counting the seconds until impact)? So does anyone have any tips, procedures, checklists, notation techniques, reference sources, or whatever that they have found to make the software planning, estimation and tracking tasks a little easier? If you have any hints that you know work well, I'd love to hear from you. I'll summarize, but if you want anonymity, I'll respect that too. I'm sort of fed up with winging it (even though most people tell me that's basically what they do too.)

Smoots and Boston geography (was: MI miles and kilometres)
It's well known that Boston has the weirdest geography (South Boston lies to the east, etc.), and that goes double for the lack of signs or signs deliberately worded to fool any but the beantown natives... there used to be a sign off the Southeast Distressway for the exit that takes you to the North End; it said: "No End". Right. Add that to the maniacal drivers who count coup (notice how many cars are dented in Boston)whizzing past you on a network of twisty, high speed roads rooted in 17th century cow paths, and it's pretty easy to find yourself on your way over the Mystic River bridge heading to Maine instead of the North End with signs like that.

The trick in gathering up only directory entries after calling FindFirstFile() or FindNextFile() is to check the dwFileAttributes element in the returned WIN32_FIND_DATA file type and if it is 16, that "file" is a directory.

What changes is the objects' actual positions on the earth, not their coordinates. In other words (-105, 40) in NAD 83 is about 150 feet east of (-105, 40) in NAD 27. If you create a point at this location and save it in a table with a NAD83 projection, and then save it to another table with a NAD 27 projection, and open both of these on the same mapper, the one that has the coordinate at (-105, 40) will be the from your FIRST layer in your mapper. The other gets a coordinate slightly different because it's being displayed in a coordinate system different from its native one.

Corpscon is free software (for MS Windows) that converts coordinates between geographic, State Plane and UTM for points in the coterminous United States. Datum shifts are based on NADCON And VERTCON, which are also free utilities. Since I forgot to mention that Alaska was my region of interest, VERTCON wasn't good enough as it doesn't cover Alaska. Further inquiry drew a reponse from Renee Shields [EMAIL PROTECTED] who said: "The VERTCON transformation is based on grids created from the differences between the NGVD29 and NAVD88 heights, but the vertical network is so sparse in Alaska that reliable grids could not be created. My best suggestion is that you locate a bench mark near the area in which you are working which has both NGVD29 and NAVD88 heights. A helpful tool to identify points is the NGSmap found on our web site under "Retrieve data sheets": http://www.ngs.noaa.gov/datasheet.html.

MI How to avoid importing indentical objects?
I have a need to import map objects into a table from various mif files via a MapBasic app, but I need to prevent map objects from being appended into the table more than once. I was thinking of computing a hash index based on various object properties (e.g. type, centroid, length, perimeter, area, etc.) and using that to see if an indentical object is already loaded. Has anyone tried that approach, or does anyone have any thoughts about this method? Are there other, perhaps simpler or better techniques to screen imported objects for duplicates? (I can't use the data attributes because I can't gaurantee that a unique key can be maintained.)

Re: MI spams
A while ago I closed the list so that only subscribers could post messages, hoping to take care of this sort of thing. Unfortunately, a lot of people read MapInfo-L via corporate gateways and web "mirrors", and are not actually subscribed. When the list was closed, they found that they could no longer post messages, and they were unhappy. So I made the list public again, and now we are exposed to spam. Junk mail tends to grow exponentially, and though it's at a low volume now, I expect we'll see more. We cannot filter it automatically at the server, and I don't want to volunteer to do it manually, so source-filtering is not an option. Other options to counter spammers involve tracing headers and elminating the mule servers (these are machines with poor security that spammers use to deliver their payload), or attacking the businesses they are trying to promote through complaints and reporting the illegal scams to the FTC and BBB (www.ftc.gov and www.bbb.org). This takes a lot more energy than it seems to be worth, but if you get mad enough, it's a great channel for anger. You might even nail one or two of the pinheads. There are also sub rosa options, but we'll leave those up to anonymous altruists who would rid us of these troublesome beasts. For the rest of us, the easiest option is to filter spam on your own end (using built-in filter tools that come with your mailing software.) For the ones that still get through, just delete and forget. Once the level of spam rises to a point where even that is intolerable, we can close the list to non-subscribers. It's sort of a question of balancing pros against cons. We could also move the list to better server software, and currently we are testing a new version of majordomo at Direction Magazine. I'll post more on that as it becomes a real option... - Bill Thoen P.S.

MI Do we want to create a MapInfo Newsgroup?
Recently, several people have asked me if we should consider starting a MapInfo Usenet newsgroup in addition to (or instead of) the mailing list we use now. I thought I'd toss it out for discussion and see what everyone thinks. First of all, Usenet newsgroups take a little effort to set up. We would need someone who has access to a newsgroup server who would volunteer to be the "maintainer" (this would not be me; I have too much going on as it is right now). After we get the initial issues sorted out here, the official Usenet process starts with formal a Request for Discussion (RFD) on news.announce.newgroups, then we need to find a volunteer site to tabulate votes, then there's a call for votes. If we get enough votes (and people outside the MapInfo community can and will vote too, so you need to be coherent and persuasive in laying out your arguments) then the maintainer can start posting the messages to servers to start propagating the newsgroup across the world. Getting a slot in the "Big 8" hierarchies makes propagation very easy, but you have to have the votes. The process can take 2-3 months. A quicker route is to create it under the alt or other non-big8 hierarchy. That's faster to get started, but much more difficult to get widespread coverage because many servers won't carry alt newsgroups unless specifically asked (and even then they still might not; alt groups are known for carrying a lot of worthless twaddle). For more info on the process see the news.newusers.questions FAQ or read news.groups for a while or go read about it at http://www.geocities.com/ResearchTriangle/Lab/6882/ncreate.html. There's plenty of arguments pro and con, but I don't want to sway people one way of another at this point. Post your comments publicly, and if there's anyone out there who wants to offer to be a maintainer/moderator and champion the cause, throw your hats in the ring! For everyone's information, there are currently 1143 subscribers on MapInfo-L. Some of those are gateways and many people read MapInfo-L from various web mirrors, so I don't really know how many "eyes" really read this list. My guess is that to get the votes to create a big 8 hierarchy like comp.infosystems.mapinfo, or sci.geo.mapinfo or whatever, you will need to really get the vote out.

Re: MI Do we want to create a MapInfo Newsgroup?
Robert Karr wrote: What's a "Newsgroup", and why would that be better than what we have?? Bob A newsgroup is a wide open open mailing list, with the main difference being that all the mail resides on a server near you. Your software can do all the same things with mail posted here (read, send, search, thread, etc.) except that it doesn't fill *your* mail box with mail. You have to connect to an NNTP server (ask your ISP for the address of their news server) and you have access to literally zillions of email based discussion groups. The big GIS one is comp.infosystems.gis, but you can also look at AutoDesk, ESRI, Integraph and other special forums that are narrowly focused on just about any topic you can imagine. And I mean ANY topic!! However the first trick is try it out. Ask your ISP how to access their news server. If they don't have one, you are not getting the full firehose information stream you should be getting. Tell the ISP what software you use to get your mail, and they should be able to help you get set up. Then subscribe to news.answers or news.newusers.questions and news.groups, and watch those for a few days; you'll get the idea pretty quickly.

However, I don't believe anyone can copyright a data format anyway (or ESRI, MapInfo, AutoDesk, and Integraph would have sued each other to death already), so if you can figure it out you could probably use it without any problems. Good luck figuring it out. Only a few illuminati know how, and they all think the others haven't got it right yet. I have noticed that interest in this format has really increased in the last few months, so I guess the genie is just about out of the bottle anyway.

(I just can't stand having to work in a DOS command line!) Here is my "take" on the software: 1. The code is a very good start, but it is unfinished in several respects. For example, the functions it provides are "read/create" rather than "read/write." Thus you can create a TAB file from a MIF/MID, but you can't open a TAB and add new objects to it. You (apparently) have to convert the TAB to a MIF/MID using the Tab2Mif, delete and/or add updated objects (in MIF/MID format), then create the updated TAB using Mif2Tab. 2. The software (apparently) doesn't do any "intelligent" grouping of objects. Thus the objects appearing together in an object block (a type 2 record) are not contained in some minimal bounding rectangle (as they are in a TAB built by MapInfo itself). 3. The conversion from external floating point coordinates to internal integer format is based on the minimum bounding rectangle of the contained data rather than limits that allow arbitrary coordinates anywhere on the ellipsoid. Thus, if you use MapInfo to update a TAB created by MITAB you will find that no data can be added outside the bounding rectangle of the original data. (Fortunately, fixing this problem in MITAB is rather simple.) However, given these reservations, I believe this is an excellent start toward an "open" set of software for working with data in Mapinfo "native" format. And, of course, just having a Mif2Tab and Tab2Mif capability (albeit experimental) is a big step forward in itself.

MI Corporate influence on the USGS
Here's a sad laugh. The new filtered National Elevation Dataset (NED, at http://gisdata.usgs.gov) is not available in either the good old *standard* DEM format, nor is it available in that new, irritatingly difficult SDTS format that we've recently had to embrace like a saguaro cactus (and how much trouble have we all gone to already to work with the established standards?!?.) No, these data come in ArcGrid format, a proprietary ESRI standard. Officially it is also available in GRIDFLOAT (an open ASCII format also designed by ESRI) and bil format which is a common non-prop graphics standard too, but just try getting a large area (like a whole state or the whole country) in anything other than ArcGrid. The USGS can't do it yet. Or at least there's a long wait. With so many open and published GOVERNMENT standards that support elevation data, why can't they produce NED in one of their own so all of us get a fair shot at it? It's really too bad that the USGS has to use software that doesn't support their own formats and they no longer have enough technical people to provide data in any of these published formats. I wonder what the world would be like today if the USGS had embraced the Open Source concept, gone with GRASS and other open software to produce and maintain our national data assets. I hope they are considering the idea of migrating to a full Open Source solution before the commercial-dependence shackles get welded on too tightly to shake off.

Re: MI MB: Call dll with a 4Bytes float instead of 8Bytes float?
This is a difficult and messy problem, but I can offer some ideas. First, there's lots of web pages that explain the details of floating point numbers. Microsoft has a pretty good one: http://support.microsoft.com/support/kb/articles/q42/9/80.asp, but there are many others. This trick uses the method of fooling the software into placing floating point bit patterns into an integer and then you access the bits and bytes of the parts in MapBasic by using integer division and the mod function. So pass your 'Value' variable to your DLL as an MI integer. Since you are passing it a 4-byte chunk of memory (which is what an integer is as far as the computer knows), your DLL will cheerfully accept it and fill it as a 4-byte Single. When it comes back, you want to convert its bit pattern into an MI float by interpreting the bits as they are packed in the f.p. format. A VB Single (an IEEE 32-bit floating point number) has this bit pattern for its 32 bits: s fff Here s is the sign (1 = negative), is the exponent biased by 127 (so you can have exponents in the range of -126 to 127; -128 and -127 are reserved to indicate special conditions) and then the last 23 bits are the fractional part of the mantissa. Also, in IEEE f.p. numbers the highest bit of mantissa is dropped, and the exponent adjusted accordingly, so in reality there are 24 bits of mantissa with the high one (which is implied) always set to 1, and you have to add it back in. So when your integer returns, the bits need to be taken out into three numbers; the sign (either -1 or +1), an exponent (a signed value between -126 and 127) and the mantissa (you can use an MI integer). Then to construct your float value, add the missing 1 back into the mantissa (which is considered to start with the decimal point) and the formula is just: sign * (1.mantissa) ^ (exponent - 127). To break out the bits in an integer, you just use the integer divide and mod functions like so (assuming n is your integer): bit0 = (n \ 2^0) mod 2 bit1 = (n \ 2^1) mod 2 bit2 = (n \ 2^2) mod 2 bit3 = (n \ 2^3) mod 2 ... bit31 = (n \ 2^31) mod 2 To build a 32-bit number from bits it's: n = bit31 * 2^31 + bit30 * 2^30 + ... + bit1 * 2^0 Here's an example. Say your integer number for Value comes back as 1097544499. in hexadecimal notation that's: 41 6B 33 33 Converting to bits and matching up to IEEE bit format yields: s fff 0 1010 1101011 0011001100110011 So the number will be positive (s = 0), it's exponent is 130-127=3. Prefixing the missing 1 to the high bit place of the mantissa we have (note the binary decimal point): 1.110101100110011001100110 Raise this to the 3rd power (in binary, you just shift the decimal point to the right), and arrange the bits into byte sizes, you get: 1110. 10110011 00110011 0011 converting to decimal, you get 14. + 179/256 + 51/256^2 + 48/256^3 = 14.7 You can verify this with the following teeny-weeny VB program (which might give you another hint at a way to convert numbers): Private Sub Form_Load() Dim f As Single Dim i As Long Me.Show f = 14.7 Open "c:\tmp\test.bin" For Binary Access Read Write As #1 Put #1, 1, f Get #1, 1, i Close #f Text1 = Str$(i) 'This value is 1097544499 End Sub - Bill Thoen Franck Martin wrote: In MapBasic I declare the following external function : Declare Function getnodevalue Lib "SomeoneDll.dll" (ByVal Index As Integer, ByVal Code As Integer, Value As Float) As Integer and define the following constant Define EN_PRESSURE 7 when I call the Function with myopen = getnodevalue( nodeindex, EN_PRESSURE, pressure) It returns wrong values.

SUM: MI Can MapBasic call routines in ActiveX DLLs?
The question was: "...can you make ActiveX DLLs that can contain functions and subprograms that can be called from MapInfo [via MapBasic] like you can with the earlier style DLLs?" The answer is: "No." Some people confused Windows API functions with ActiveX DLLs, but in fact, these are regular DLLs, and so can be used directly in MapBasic. However, you CAN make a resource DLL to provide tool button icons to your MapBasic app (See Chris Martin's Feb 1st, 2000 summary on this, "Re: MI Resource Files/DLLs - summary") For those who want the dirty details, Chris Martin explained that the new VB5/6 DLLs are ActiveX DLLs or COM Servers. Basically, this means that if your development language isn't COM compliant, you lose. Access to ActiveX functions require COM support which is what makes them "visible" to an application, and MapBasic is not COM compliant. Chris also mentioned that there may be ways around this, but they would involve some sort of bridge written in C++ that serves as an interface to your app. He also thought that Desaware's SpyWorks may be useful here. He adds: "In normal DLL's an Export Table is generated where all public function names and their parameters are written. Any program can then import that library (that's what you do when you DECLARE an api function) and use its functions. Unfortunately, as VB DLL's are COM servers, the only functions that they export are to register and un register the server. There's no other functionality you can access." Brad Matthews added: "VB created ActiveX DLLs (and ActiveX EXEs) can be used by any other language which supports the COM interface (C++, Powerbuilder, Delphi, VBA, ASP). MapBasic does not support the COM interface." Richard Burkmar added some interesting perspective by pointing out that the main issue is that MapBasic is not COM-compliant, and that the future is with development tools that are; like MapX. He says: "The Component Object Model (COM) is central to the Microsoft Windows environment and there probably isn't much of a future for development environments which don't support it. Nowadays, most do - for example any development environment in which you can incorporate a MapX map is COM compliant. MapX exposes its functionality as a COM component - if it didn't it wouldn't have got off the ground."

Unless somebody wants to set up a separate email list (note: not another web browser "list") for MapX, I don't see why this forum wouldn't do the job. Just precede your subject lines with something like "MapX:" to alert people about the content of the message. There's good arguments for serving mailing lists via email vs using web pages. Each has their strengths and weaknesses, and some of these are weighted differently by different people according to personal taste. Personally I prefer email servers for email. They're more open and flexible, IMHO. All we need to improve this one is a daily "digest" option to cut down the load of separate emails each day. MapInfo has set up a great search tool for this list at http://testdrive.mapinfo.com/tdc/mapinfo-l.nsf/?openabout, and we also archive all the past messages at http://www.directionsmag.com/mapinfo-l/digest/. For those who are interested in MapX, perhaps you don't know that MapInfo's MapX list is at http://testdrive.mapinfo.com/tdc/discuss.nsf/mapx+discussion?openview, and it's pretty busy. BTW, you have to register to get a password before you can use that list. It's free, but go to http://testdrive.mapinfo.com/tdc/home.nsf?OpenAbout and register. There are several other forums available too. But feel free to use this list for MapX talk too. I'm one who's rather interested in this subject as well, and if I read the writing on the wall correctly, MapX is where MapInfo programming is going. - Bill Thoen -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI Can MapBasic call routines in ActiveX DLLs?
A while ago Chris Martin's summary on how to get custom icons into MapInfo interested me enough to wonder what else you can do with this technique. Basically --and this works great-- you can create a custom ActiveX DLL that will allow you to use all sorts of home-made icons like so: 1) Create a new ActiveX DLL project 2) Open resource editor, and add your custom bitmap pairs 3) Save resource file in Project 4) Save and compile project 5) Distribute... 6) When selecting icon, specify pathname of DLL eg. ICON 1002 FILE "MyIcons.DLL" 7) Sit back and impress friends and colleagues, with smiley faces and Bunny Wabbits. (You need at least VB 6 or you won't have the Resource Editor.) But my question now is, can you make ActiveX DLLs that can contain functions and subprograms that can be called from MapInfo like you can with the earlier style DLLs? If so, does anyone have a small example? I know VB can't do the old style DLLs, but it's VB that I have now, so it would be neat to be able to use to make new style DLLs, if they could be made to work with MapBasic. Can this be done? - Bill Thoen -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI SUM: MapBasic training courses - Pro and Con?
s. The SQL chapter does belong in an intro course, but for beginners, only the basics of SQL should be covered, and that should be moved up to be included on a (currently missing) table manipulation chapter. Surprisingly, most "beginner programming" students have never yet used the MapInfo "SQL Select" under MapInfos Query menu! SQL select is a must-know topic if you are ever going to mess with tables programmatically. Also, there are really two levels of SQL that need to be mastered: basic table manipulation, and the more complicated object manipulation. These probably ought to be presented in two places. Just because they both use SQL doesnt mean they are in the same category. The first ought to be concerned with manipulating data, and the second with performing GIS operations with objects like (contains, within, intersects, using buffers, etc.) Neither should get too deep into SQL for a beginners course. You could spend weeks on SQL if you wanted to, so you need to draw the line somewhere. 3. Presentation Most instructors just try to follow the course workbook, and some of the problems that makes for presentation are touched on above. However, beyond that, students most often-cited issue on presentation was that they wanted more hands-on experience. For instructors that problem was also always acknowledged, and also always with the lament that theres too much to cover in such a short time to leave much room for lab work. One student responded positively to a UK course where they received about 10 minutes of lecture followed by 10 minutes of hands-on examples. Maybe the rapid back-and-forth method from lecture to lab is better than a long lecture and then a long lab (where you have less control of time.) How to get more time to present everything? A couple of possibilities come to mind. First, dont try to cover so much in an intro class. One experienced trainer suggested that for the typical beginner, topics like the Animation layer, DLLs, and DDE could be dropped and hardly missed. Maybe providing some examples on a companion CD for the student to cover those topics later on his or her own would be a better way to present these topics, or move these into a more advanced course. The lack of separate course tracks tailored to class interests came up more than once. Students want such short intensive courses taught in the context of their industry. This also saves time if everyone is in the same industry, and gives them real examples they can use immediately. Although I can think of industry applications that emphasize certain tools and techniques over others, I cant think of many reasons why you cant, for example, demonstrate "object manipulation" with examples that come from any industry. The down side to that is that providing so many alternatives is expensive and requires even more ability on the part of the instructor. I also got strong hints that a few instructors are not even able to teach the basics let alone be flexible enough to handle alternative tracks. 4. Alternative Education One suggestion was to create a version of this course (and others) on video tape. Sounds like a pretty good idea to me, and something worth considering. Overall, most people responded positively to the mapbasic courses theyve taken or had to present, so it seems like it meets most peoples goals, but its clear that theres room to do it better. Thanks to everyone who responded to my questions; youve given me something to think about! - Bill Thoen -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
