[ANN] SQLiteAdmin
I'm happy to announce the release of my first commercial Livecode application, SQLiteAdmin, a db admin tool for SQLite databases. A 30-day trial version of SQLiteAdmin is available at www.lcsql.com/products.html In recognition of the amazing amount of knowledge imparted to me by subscribers to this list, I am making SQLiteAdmin available for $4.99, a $20 discount, to any list member until midnight on Friday April 13th. Please email me off list at p...@lcsql.com if you would like to take advantage of this deal, and I will send you a link to buy it at that price. SQLiteAdmin has been tested on OS X and Windows. I do not have access to Linux (yet!) but would be happy to compile a Linux standalone for anyone who would be willing to try it and give me feedback on what changes might be needed to make it a viable Linux product. OK, now on to the sales pitch. SQLiteAdmin is a full-featured administration tool for SQLite databases that removes all of the restrictions and omissions inherent in the standard SQLite Data Definition Language. You can safely add, modify, or delete any of the properties of a table or column including name, data type, data length, primary key, foreign key, check, unique, not null, and default constraints, all while maintaining the integrity of your data. SQLiteAdmin extends the DDL even further with convenience features that provide you with the ability to add multiple columns that share the same properties with a single click, and optional automatic index creation for foreign key fields. SQLiteAdmin provides complete data export and import capability in a number of formats including csv, delimited text files with your choice of delimiter, and SQL INSERT statements. You can export all or selected rows of a table. You can also export the CREATE statements necessary to build your database, with or without the INSERT statements to populate it. With SQLiteAdmin's Utilities view, you will be able to audit your database, get recommendations for better performance, and modify any of your database's PRAGMA settings. SQLiteAdmin's Browse view gives you access to the SQLite Data Manipulation Language. You can display data from any table with filtering capability on any columns in the table, select the columns you want to view and display them in your preferred sequence, all by filling in the blanks instead of writing any SQL statements. The Browse Tool also provides complete insert, duplicate, update and delete capabilities, including modification or deletion of multiple rows in one operation. And you can save your filter definitions, column selections, and sort sequence for later use. If you need to write your own SQL statements, you can enter any SQLite command in SQLiteAdmin's SQL tool and execute it. SQL commands can be saved and recalled for later use. SQliteAdmin includes full support for in memory databases and also provides the ability to save an in memory database as a permanent disk file. A 30-day demo version of SQLiteAdmin is available at http://www.lcsql.com/products.html. Some functionality is disabled in the demo version. -- Peter Haworth lcSQL Software http://www.lcsql.com -- Pete Molly's Revenge http://www.mollysrevenge.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Zipping Up an LC standalone program
I guess my primary concern is that a user can simply download the compressed file and either have his browser autoatically un-compress it or just be able to double-click on it to un-compress it, then have the program be ready to use.

It wasn't until the Linux / FreeBSD movement that compression options were added. On most systems still using ATT tar sources, you have to compress an archive after tar creates it and decompress an archive before tar can extract its contents. We prefer tar and a compressor because it allows up to properly bundle up bits of code, regardless of the file types, and share them with others while reduing the overall footprint required on disk and for transfer. The tar app is available in one form or another on every platform out there, so you can pretty much always open another's tarball. In fact, I believe Dennis' original PDP MULTIX 9-track install tapes used a precursor to the modern tar format.

Zipping Up an LC standalone program
Been putting together a litte script to get all my files ready for a release and used the revZIPxxx commands to make a zip file of the LC standalone program - this all on a Mac. The resulting zip file is only 4kb in size, obvioulsy not correct. The code is pretty straightfroward: revZipOpenArchive myZipFile,write *if* the result is not empty *then* *answer* the result *answer* file Zip file revZipAddItemWithFile myZipFile,myApp.app,it *if* the result is not empty *then* *answer* the result revZipCloseArchive myZipFile Zipping the same file with the built-in OS X compress function works fine and so does the CleanARchiver utitlity.

It's not a problem with RunRev, or their host, but with the lazy nature of a few blacklisting systems. Actually, in this case, it is their host. GoDaddy needs to tighten up their secureserver.net environment to eliminate the spamming that occurs. Their servers are high on the list of even the most legitimate blacklist maintainers (Barracuda, for instance). I'm no fan of GoDaddy so it wouldn't surprise me if they've been willing to turn a blind eye to illegal activity to maintain that income until they're absolutely forced to do the right thing. They wouldn't be alone on this: a few years ago it was well known that some 30% of global spam was originating from three regions in Florida, but neither the feds nor the downstream providers did anything to enforce the law. Ultimately a few upstream providers got tired of carrying all that wasteful traffic and blocked it all in the backbone themselves, only after which the feds finally decided to show up for work and make an arrest. The local hosts never explained why they'd never taken care of it themselves, and sadly the reprieve was short-lived as that traffic eventually moved to the Ukraine, where it flourishes in an apparently lawless environment today. But back on topic: Blocking entire IP ranges is not a responsible way to blacklist, since it can - an inevitably does - affect legitimate users. It's simply lazy, a ham-fisted scorched-earth way to solve a problem that requires more surgical methods. In fact, it seems On-Rev.com may be a very good example of how this gets out of hand so easily, since AFAIK their servers aren't on GoDaddy at all, but on SoftLayer: http://on-rev.com/hosting/**our-data-center/http://on-rev.com/hosting/our-data-center/ And even if some accounts were host by GoDaddy, unless those specific servers are used for illegal activity there's no excuse for any responsible blacklisting service to block them.

Re: getProp syntax query
Hi Graham, Mark expalined the syntax I think. You probably already realise this, but using getProp isn't an integral part of the datagrid, I think Trevor just used it as an example. Since you're doing a spreadsheet, I assume you'd want to multiply any 2 columns together, not specific ones. If that's the case, you could consider putting a handler in the datagrid's group script that takes the column names as parameters and returns the result. Something like: function multiplyColumns pcol1,pcol2 put the dgHilitedLine of me into tLine try put GetDataOfLine(tLine,pcol1) * GetDataOfLine(tline,pcol2) into tresult catch terr return terr end try return tresult end multiplyColumns The try is in there in case one of the columns doesn't contain numeric data or the column name doesn't exist but you could ctach that other ways. Datagrids are great but it takes a while to get to grips with them!

AFAIK it was done by Trevor deVore - I am deeply impressed, even as I stumble. I am trying to implement some spreadsheet-like behaviour and have fallen more or less at the first fence during the lesson on Page 94 How do I get Aggregate Values for Columns?. I can make the example work if I follow it exactly. It depends on a getProp handler the first line of which is: getprop uSumOfColumn [pColumn] I would like to multiply two columns using this as a starting point, so I would like to refer to two columns in my getProp handler. However when I look up getProp in the LC documentation, I don't see that getProp can take any parameters at all, certainly not an array reference, so my attempt to extend this structure with a line like getProp usMultipleOfColumns [pColumn1] [ pColumn2] can't be compiled - putting a comma in between the parameters (if that's what they are) doesn't help. As you see I have no idea what I'm doing. My question is, how does the syntax of the original getProp handler work? How is the bit in square brackets allowed, and why isn't it featured in the LC documentation? If I did want to provide a getProp handler with the names of two different columns, how would I do it? I do realise there are much more pedestrian ways of achieving what I want, but it seems important to understand the mechanism shown in the DataGrid docs.

Re: Progress Bar
Thanks guys. I put a wait 0 in there and that made the progress bar update visible. Seems kinda weird that there's a difference between not waiting and waiting zero, but that's OK! This does lead to an interesting conundrum though. It takes about 2.5 times longer to process my test data with a progress bar than without one. Not talking huge amounts of time - about 1 second vs 2.5 seconds - but those times could get a lot longer in production, maybe by a factor of 10 or more, and this particular function of the application is going to be judged at least partly on performance. I calculate the update interval by dividing the number of records to be processed by 100 with a minimum of 10 to deal with small data sets. I guess maybe I can play around with the divisor of 100 to see what yields the best blend of performance while still showing progress. I might also try using an animated cursor to see how it compares performance wise. Isn't there some rule of quantum physics about changing the outocme of an experiment by observing it?

Re: LiveCode Player for 5.5
Hi Alejandro, I think the discussion of whether education brings everyone down to the lowest common denominator is a different topic! I guess my original point, perhaps not well enough explained, was that, according to the study in my local paper here in California, using iPads to replace text books costs about 4 times more than using the hard copy text books. Personally, I can't find any justification for California schools spending that extra money when there's hardly any evidence that using iPads improves the quality of eduction at all, never mind 4-fold. I don't know enough about it to judge whether the problem is hardware, software, good vs bad teachers, lack of teacher training , or any other cause.

Re: LiveCode Player for 5.5
I'm not a teacher, nor involved in education in any way so take what I have to say with a pinch of salt. A recent analysis over here in California found that it was around 4 times as expensive for a classroom to use iPads and electronic versions of text books as it was to continue using hard copy text books. The costs were measured over a 6 year period to take account of new editions of the text books and the life span of an iPad and I believe the analysis was done for high school level classes. I'd be prepared to accept the extra cost if it was accompanied by a greater than 4-fold improvement in educational quality but there seems to be precious little evidence that the use of iPads produces any increase in educational quality. This is all related to general education classes, not computer science classes. Of course, you can find studies to prove/disprove just about anything you want these days. For those interested, you might want to read the book Wrong by David H. Freedman. A fascinating account of why an alarmingly high number of studies carried out by experts come to completely wrong conclusions.

And given the vast time scale involved, it is also logical to assume these alien civilizations will not have evolved simultaneously (criterion #1) The second criterion is that the radio active stages of technology of these civilizations will be short relative to these same vast time scales. I'm sure that I am not the first to define this criterion, but I have not seen it discussed before. The validity of this is discussed very briefly in the simulation notes. Further to this point, I would argue that ALL technologies have limited durations, and the simulation allows you to adjust it over a very long range (albeit short relative to the vast time scales of our galaxy) to your heart's content. I would be happy to discuss this at length, but it might be best to do so off-list?? My simulation starts with these assumptions and explores the outcome. These criteria are simply derived from the statistics of the numbers involved. There are many more qualified than I to explain the statistics involved, and a few references are included in the notes of the simulation.

Re: [OT] A couple of links about Gnome and usability
Hi Richard, This thread has been very interesting to me as I'm considering getting a computer to run Linux. The problem I'm having is illustrated by the snippet from your post below. I'm a computer savvy person and worked with them most of my working life but I know nothing about Linux and really have no desire to spend much time installing and configuring an OS. I can buy a Mac or a PC, switch it on and it just boots up and runs. But where do I buy a computer that runs Linux and what version of Linux (if that's the right term) I need? I have pretty basic needs for this machine. Aside from running Livecode on it, I mostly need a web browser (I use Google tools for just about all my daily needs) plus some way of playing music. I already have a Windows laptop that I only use for testing out the LC apps I develop on my Mac. I don't really want another computer. It seems like Apple has just about shut the door on running anything but OS X on their computers. Can I install Linux on my Windows computer a dual boot it somehow? I'm sure these are pretty basic questions for people who are familiar with the Linux world, but I think they illustrate why the use of Linux is not more widespread, no matter what advantages it has over other OS's.

But where do I buy a computer that runs Linux and what version of Linux (if that's the right term) I need? Every distro has its fans, some quite passionate. There's a running gag in the Ubuntu forums that whenever someone encounters an issue that's hard to solve, the answer is use Arch. :) Personally I like Ubuntu, and as a developer it's important to me that I'm working with the most popular distro (an estimated one-third of Linus desktops are running Ubuntu). With its mandate of Linux for Human Beings, it's provided a good experience for me. Mark Weider uses Fedora, and I've enjoyed that one as well. Linux Mint is another good choice. Whichever you choose, be sure to post all over the Internet that users of other distros or OSes are stupid fanbois who just don't get what Linux is all about! That'll help keep the myth of the Linux community alive for those who have no familiarity with it. :) If you were in the market for a computer with Ubuntu pre-installed, these companies are good options: http://www.system76.com/ http://zareason.com http://linucity.com While all three are very reputable vendors, the last there, LinuCity, is owned by my friend Aviv and I can personally vouch for the quality of service he provides. For more options, Canonical maintains a list of computers from major vendors they've worked with that have undergone their certification process: http://www.ubuntu.com/**certificationhttp://www.ubuntu.com/certification Note that that's only a subset of computers Ubuntu is compatible with. There are only so many hours in the day, and even a billionaire like Mark Shuttleworth can't afford to certify everything it runs on. One upside to Linux being mostly installed on computers designed for some other OS is that it expects that challenge and usually meets it pretty well. In my own experience, every machine I've installed it on has worked great out of the box. The only time I needed a special driver was for the NVideo card on my Dell Vostro, and Ubuntu identified that and prompted me to install it with one click on first boot. I already have a Windows laptop that I only use for testing out the LC apps I develop on my Mac. I don't really want another computer. It seems like Apple has just about shut the door on running anything but OS X on their computers. Can I install Linux on my Windows computer a dual boot it somehow? And even on your Mac. Apple's OS X EULA only prevents you from legally installing it on anything other than an Apple branded computer, but their computers are frequently used by members of the Ubuntu forum for running Linux. Boot camp is a natural fit for that sort of thing. Because Apple tends to get specialized components, it can sometimes be trickier to get a solid install on a Mac than on popular PCs where the components are in such wide use that there are plenty of good drivers for them. Dual-booting with Windows is a popular option, esp. among gamers because Windows still rules the roost with the games market. I've set up dual-boot systems before and it's not hard (the Ubuntu installer includes options for that), but personally I found I was booting into Windows so rarely that I ditched that partition and put Windows into a VM within Ubuntu. In general, the sweet spot for Linux is computers between two and six years old. It can often run on newer systems, and even most older ones (Puppy Linux can run on darn near anything), but if a computer's too old it won't have the horsepower to deliver a great experience with the latest Linux distros, and if it's too new there's a chance of needing a driver that hasn't been made available yet. Even then there's almost always a way to get things to work, but for a simple first-time experience the two-to-six years guideline may be helpful for systems that haven't been certified. Most of the popular distros allow an option to run the OS from CD or USB drive, so you can try it out on a machine without having to install anything.

Displaying PDF files in an LC stack

Been having some issues getting that to work but even if it did work, I don't think it will satisfy my needs. I want to use the pdf feature of showing bookmarks in a navigation pane (like the datagrid manual) and apparently that won't happen, at least on a Mac. I could, of course, simply launch the pdf file as a separate process but I'd really like to keep the help file within my LC stack if possible.

Dictionnaries exist to clearly define the meaning of a word or phrase in another language.

If we can try and forget the environment of our computer translation (files, folders, disk drives, et tutti quanti), we can try to home in on best best translation available for a specific language. The French language (to my knowledge) lacks the precise equivalent of the English into (which means from the outside of ... to the inside of ...). So may we fall into the trap of personal interpretation ! The French a denotes location only, but gives little information concerning the direction, and even less about the subtleties of inside or outside. I find it to be the worst possible translation. The French dans means in or at best inside, and has no implication of the 'into I show above. However, I find it a better solution than a. The French sur implies lying on top of and certainly does not imply inside. Much depends on the personal interpretation. As a long-standing nit-picker I would never use this. The French vers means in the direction of, which I find to be acceptable in the translation you request, because it simply skips over the notion inside, (but nevertheless implies it (The idea of copying a file to the outside of a folder would be nonsense !).

Re: Need an example of how to use try and catch
Bob, Maybe I'm missing something but you seem to be saying there are some database errors that can only be detected by using try/catch, not by checking the result or the revdberr string. Taking your example of a database going away, I just created a small db, opened it in LC, then deleted the db file. Any further accesses to the db in LC came back with an error without using try/catch, so I'm not understanding why a try/catch is necessary. Not saying try/catch might not be necessary, just trying to understand if I need to start using that approach. My test was done using sqlite so maybe other SQL variants is where try/catch is needed or perhaps it's due to your use of SQLYoga. Pete On Thu, Mar 22, 2012 at 4:10 PM, Bob Sneidar b...@twft.com wrote: When you are in a standalone, a runtime error that would halt execution might be fatal. Try/Catch allows you to handle the error gracefully without presenting the user with an ugly dialog and a QTD afterwards. You can politely inform the user that something has gone wrong and you have to exit the application, after tidying things up a bit if necessary. Databases can just go away sometimes, like the IT guy deciding it's time to update the servers and restart them while the user is working late on an important project. Setting a repeat loop around a try/catch construct allows you to attempt a reconnect a certain number of times, or present the user with a Retry/Cancel dialog, allowing you to clean up and exit gracefully if necessary. As a case in point, I was having a problem with a low level broadcast storm which was causing the uplinks on our switches to reset (they are designed to do that). Anyone who uses Microsoft SQL knows this can be fatal, depending on how the software is written. Our accounting software was not very well written, and as a result, the end user was subject to a never ending stream of error dialogs allowing a cancel, retry or abort! None of them exited gracefully. ICK!! Had the developer accounted for the possibility that the user could be disconnected from the database, and provided a graceful exit, my reputation would not now be so tarnished, because they all blamed me of course. :-) To the accounting girl's credit however, they did make me brownies when I found the source of the broadcast storm and fixed it.

Tools for creating a help file
I'm trying to decide how to supply the help text for an application and wondering what tools people are using to creat help files. I'm finding that it is much easier to use a word processor to write the help text and graphics than trying to do it within the confines of LC text fields. I can't leave the help text as a separate file because that would require the user to have the same wp program I used to create it. I can create a pdf version of it to get round that but I'm wondering if there is some way of importing the help text into LC, retaining all the formatting and graphics. Is it possible to open a pdf file and display within an LC application without starting a separate pdf viewer program?

Re: Tools for creating a help file
Thanks Richard, that sounds like a possibility. I'm using iPages to create the help text but I think it is capable of saving a file in Word format although not sure how good a job it does. I guess I'll give it a whirl with WordLib (hopefully there's a trial available) and see what happens. I'm not against typing into LC fields, just finding that there's less work involved in using a word processor that is built to deal with formatting, spell checking and inserting graphics that doing all that in native LC.

And he's hard at work on a new version that takes full advantage of LC 5.5's new field object capabilities. For professional devs he also offers an option to acquire limited rights to the source for an additional fee. This is a must-have for myself and my clients, and pretty much every other pro dev who need to consider code base longevity, and his source fee was more than reasonable.

Re: Tools for creating a help file
Folks, Still playing around with different formats for this. One possible format is the one used by the Datagrid reference manual. It's a pdf file including a navigation pane on the left with expandable/collapsible entries; clicking on an entry goes directly to the associated page. Pretty sure this is a built in feature of pdf files, but wondering if there is a way to create that type of format from a standard word processing program as opposed to purchasing Acrobat.

Re: revCopyFile
Hi Geoff, Thanks for the speed test info. I'm not very familiar with shell commands so maybe you could let me know the command to use? What I need to do is copy a file to a different folder with a different file name.

Re: Need an example of how to use try and catch
You're getting an error because the catch part of try takes only 1 parameter - the variable that holds the error - not two as in the script. Also, as noted by Peter, the try statement doesn't help you with the specific example you used since getting a non-existant custom property doesn't cause an error.

Interesting, never thought of that. Is there an advantage to doing that over just issuing the database call and checking for an error right after?

Re: revCopyFile
Hi Jacque, Yes, I saw that in the dictionary. I don't think there's any metadata in the files I will be copying (straight .txt files) but I'll have to check that before going down this path. I found the files function in the dictionary and it includes the file size in one of it's formats but it lists all the files in the default folder, not an individual file.

Re: MySQL joined select
Hi Marek, I think you're confusing what you get back from the SELECT statement with what you display to your users - they are two different things. I'm going to assume that you need all the columns you name in your SELECT statement for some processing reasons but that doesn't mean you have to show them all to your users. Once you get the data back from the SELECT, it's up to you which columns you put in a filed, datagrid, or any other Livecode control. Maybe you're thinking that you have to SELECT the column because you refer to it elsewhere in the SELECT statement, but that's not the case. You can refer to any columns form the selected tables anywhere in your SELECT even if they are not explicitly selected.

Re: MySQL joined select
Hi Ken, Good catch on the multiple FROM clauses, not sure what that's all about. Probably just needs to qualify the columns in the condition with the table name. The SELECT statement has a lot of problems in general. There's no JOIN statement to link table1 and table2 together, for example. That might work as long as the column(s) to be used to join the tables together have the same name in both tables but in general, it's much better to explicitly define the linkage with a JOIN statement - for clarity reasons if no other. Just one comment on the need to qualify columns with table names. I definitely agree it's good practice to do that for clarity but as long as a column name is unique among all tables, SQL will figure out which table an unqualified column name belongs to.

You only include the columns you want back in the SELECT part of the query: SELECT travel_days FROM … Also, although I know you provided a dummy query, be aware that there are two inherent problems with the one you provided: 1) If you have multiple tables in the FROM clause, you need to identify the table attached to the column in the SELECT clause (although some SQL engines might just assume you meant the first table, it's good form to identify the table), either by full name: SELECT table1.travel_days FROM table1,table2 WHERE… or by alias: SELECT t1.travel_days FROM table1 t1,table2 t2 WHERE… 2) I'm not sure what from transport means since you already have a FROM clause in your example query The bottom line is that you don't have to include columns in the SELECT portion of the query that you don't want back, so long as you identify them properly and they actually exist in the table you're referencing. Just be aware that LiveCode's text parsing is second to none, so there are usually times where it may actually be easier and more efficient to let SQL handle getting the data, but let LiveCode handle parsing the data after it arrives. As I mentioned in an earlier post, you *can* use SQL to change your numbers to + symbols, but it's ugly - Mark's method to post-process it in LC with a single statement if far better (IMHO).

Re: Failing to understand the oddities of the line chunk
I think it's unlikely anything about this behavior will change no matter what bug report is filed. There's the backward compatibility issue you raised (although I personally think that is usually a cop out) but you could also argue that what happens is by design. I'm thinking your hope for a more right answer is probably in vain at this point!

Lost in this discussion is the reason why someone wanted to do this in the first place. Alex, I think it was you that started this whole thread - did you have a specific reason for wanting to specify a line range with an end point before the start or was it just an observation? No, no specific reason to want to do it - it kind of happened by accident :-) And it wasn't so much an observation as a question - can someone give me a rationale for this behaviour so I can deal with it better ? What I *wanted* to do was replace line 'x' of someContainer (and everything after it) by my new data, so I did the (temptingly logical - but WRONG) thing of put newData into line x to -1 of someContainer NB that is simply wrong, because line -1 means the last line that is there - not to the end after what I specified :-) as it happened, the container had x-1 lines in it at the time (including a trailing line delimiter, just to confuse things), so that became equivalent to put newData into line x to x-1 of someContainer I knew that what was happening seemed wrong - but couldn't figure out how or why. Jacque's explanation showed me what I should do - but still left that niggling feeling of something being a bit odd. I can get what I wanted in a couple of safe ways a.delete line x to -1 of t!! inverted range - but AFAIK it does the right thing with it in all cases put newData into line 2 of t b.put newData into line 2 to kInfinity of t -- where kInfinity is some arbitrarily large constant I'm not sure what I would vote for now, hence I haven't yet put in a bug report.

Re: Text formatting for a slider
Yeah, but that displays all possible properties of any object. The properties property of an object gets you an array of properties for a specific object. Still a long list mind you, and not a complete list either according to the dictionary. I think you're probably right that it would make the inspector windows very unwieldy to include all properties. The problem is that by leaving some of them out, arbitrarily, it gives the impression that they aren't available, especially to new users. I remember when I first started using LC and wanted to set the behavior of an option menu button - there's no inspector window behavior field so I just assumed it wasn't possible for some reason and went down a different, much more complicated path. Seems like it would have been trivial to include one more option in the inspector option menu for All Properties or something similar. I ended up writing my own plugin to show all the properties of a selected object and allow me to change any of them.

Re: help pls
Hi Marek, I have to admit I'm not fully understanding the requirement you described on the forum but if you need to have a calculated value column based on other columns, you can have the database do that by defining a triggers that will happen every time an INSERT or UPDATE is done to the table in question. That way, the db does all the work for you and all you have to do is a simple SELECT for the calculated column. The syntax for creating a mySQL trigger is at http://dev.mysql.com/doc/refman/5.5/en/create-trigger.html. It would look something like: CREATE TRIGGER mytrigger AFTER INSERT ON thetable FOR EACH ROW UPDATE thetable SET PRICE to (NEW.Col1 * New.Col2) WHERE id=NEW.id You would also have a second trigger defined as AFTER UPDATE. With those triggers in place, just SELECT PRICE FROM theTable. Hope that helps.

Re: Sqlite and performances in LiveCode
Hi Trevor, Sorry to keep coming up with new quirks but I have another strange situation regarding GetDataForLine. Under some circumstances, the data that I supply from GetDataForLine ends up in the datagrid starting at the 13th line instead of line 1 and the first 12 lines have data in them from the previous cycle of GetDataForLine. One GetDataForLine cycle deals with 12 lines. I'm using the datagrid in question as a general purpose viewer of data from any table in an sqlite database. The circumstances that cause the problem are if I have data from a table displayed, then I filter it in some way, so the number and format of the dg columns is the same but the rows contain a subset of the original data. If I select a different table and therefore change the number and size of the dg columns, the correct data is displayed. I set a breakpoint at the end of GetDataForLine and can see that I am sending the correct data back to the datagrid in pDataA and pline starts at 1 and continues correctly up to 12. If I refresh the datagrid either from its Inspector palette or by script, the correct data turns up at the top of the datagrid although that invokes another cycle of GetDataForLine. Also, if I scroll down the datagrid past the 12th line then scroll back to the top of the datagrid, the correct data turns up. If I scroll less than 12 lines then back, some of the incorrect lines still appear and the the rest of the lines are correct. For example, if I scroll down 4 lines then back, the first 4 lines have incorrect data and the rest are correct. It seems like this must be something I'm doing wrong in my code but the fact that I see the correct data being sent to the datagrid for the correct line from GetDataForLine seems to argue against that. Can you think of anything that might cause this behavior?

Hi Dick, Thanks again for this tip. I ended up using it to solve my problem by passing the whole array variable along with an optional second parameter which is a list of comma-separated key values. The function turns the key values list into an array then uses it to access the data array. If the first parameter is a simple variable, then the second parameter isn't present and the function can access it directly.. I'm wondering how you found about about this key values array feature?

Re: Sqlite and performances in LiveCode
Hi Trevor, Thanks for making that change. I've been following up a bit more on the behavior of GetDataForLine being called in repeated cycles for the number of lines in the datagrid. As a reminder, the datagrid has 11 visible lines, GetDataForLine gets called once for lines 1-12, then a second time for lines 1-2 again, and occasionally a third time for lines 1-2. I think I know the reason this is happening. The first GetDataForLine cycle happens when I set the dgProps[Columns] property of the datagrid. The second cycle happens when I set the dgNumberOfRecords property. There's a possible third cycle because sometimes I set the dgProps[Sort By Column] property. I have tried setting the dgNumberOfRecords to empty, zero, or NULL before any of the above properties are changed but it doesn't seem to make any difference. Hoping you may have a recommendation as to how to avoid these multiple cycles!

Even a reference to an element of an array is a statement of sorts. That the command is in essence the characters for key delimiters [] doesn't change that. The array that is an element in a multidimensional array is not itself a container. The array is the container.

Re: Passing parameters by reference
Dick: Thanks for the script, another little nugget of knowledge added to my LC store! I have entered an enhancement request - it's # 10070 Dar: The function in question is a general purpose one that gets called from many places. Sometimes I need to pass an array element and other times just a simple variable so I'd rather not complicate things by passing in an extra parameter that holds the array key if it is an array that's being passed. But that is a possible solution so thanks for the suggestion. Bob: Creating a temporary array works, of course, and that's what I'm doing for now. But it defeats the whole purpose of passing the parameter by reference since now I have to put the temporary array back into the real array after the call. I may as well just change the function to return the result of its code and pass the parameter by value instead of reference.

Re: Sqlite and performances in LiveCode
Hi Trevor, The properties you mentioned are both set correctly. I tried logging executioncontexts but everything looked exactly the same each time though. I also logged the line number parameter of GetDataForLine each time through and displayed them immediatly after the line of code that sets dgnumberofrecords and it showed the line numbers there twice. I'm concluding that it's not something in my code, since the display is right after setting dgnumberofrecords and there's only one call to it. However, it's not really a big deal, the amount of time consumed in setting up 12 lines twice instead of once isn't worth worrying about. I was really letting you know about it in case it was a known bug. Incidentally, I was wrong on the number of lines in my datagrid. As in your example, GetDataForLine seems to get called a couple more times than there are lines in the datagrid. Theer are eleven lines in mine and it is being called 12 times.

Re: Help with C externals
Hi Monte, The callbacks that Paul mentions in his reply is one thing - would be great to be able to display some sort of progress messages during a lengthy db operation. But seems like that might be a problem according to Paul. I guess I've come across several niggling issues in the last few months. The latest one I found is that revDatabaseColumnNames took around 1.5 seconds to retrieve the column names for one table. I'd been chasing my tail trying to find the cause of slow performance thinking it was something to do with datagrids or slow sqlite performance, but turns out to be LC. Using the equivalent PRAGMA to get the column names took hardly any measurable time. During the same exercise, I create a cursor with a SELECT rowid FROM table statement. Right after that, I issue a revDatabaseColumnNamed call for rowid and get an error that the column doesn't exist. I found from calling revDatabaseColumnNames that the cursor has used the primary key column of the table instead of rowid. Arguably, that shouldn;t be a problem but I I select rowid, then rowid is what should be in the cursor. I can get round it by using revDatabaseColumnNumbered. If you followed the recent thread on putting empty into integer column in sqlite, you'll know that when you get the data back out agin, it comes back as zero, not empty. Similar to the rpevious example - you should get back whatever you put in. I should add that QCC folks have recognised this as a bug and plan to fix it. On a performance front, there's been a recent thread regarding how much faster SQLiteManager is than the LC equivalent calls. Turns out a lot of that was because of a neat technique used by SQLiteManager but there's still a performance issue. Issuing SELECT rowid FROM table in LC takes about 5 times longer than it does in SQLIteManager for the same table. I'll admit that the numbers are small but for tables with large enough number of rows, that's a significant amount of time. There's a number of useful SQLite externals out there. These are usually funcations that you can include in SELECT statements or expressions. SQLite provides a function to load external libraries but it only works if that functionality is enabled when the database is opened. LC doesn't provide a way to make that happen and there is no PRAGMA way to do it. There's more but this is already too long! I'll finish by saying that most of the stuff I'm writing is in the nature of general purpose tools for SQLite db administrators and developers so I'm probably using LC calls that wouldn;t be used by the majority of people who develop a standard app using a database with a known structure.

Hi Paul, Yes the callbacks are certainly one of the things I want to get access to but you're raising doubts as to how feasible that might be. But there are other things too.

I'm finding too many little inconsistencies and inefficiencies in the rev routines. The problem is I know nothing about using external libraries with LC or the sqlite C API.

Check out http://www.sqlite.org/c3ref/intro.html for documentation of the C APIs for sqlite My experience with externals is that it is just a load of busywork to write an interface layer that calls external functions. The difficulty arises when you need to deal with callbacks, and I assume SQLite uses some mechanism like this for reporting progress or timeouts, or allowing long operations to be aborted. So that's what you should investigate first, to decide whether you can do everything you need with an external. In the past, I've dealt with the issue of callbacks from asynchronous events by having those callbacks record their state in a variable or fifo, and then use timer messages to poll the variable or fifo at a rate sufficient to the application. But that doesn't deal with callbacks that occur during the time when a function called by your code is in progress, since you're not handling timer messages during that time. -- Ciao, Paul D.

Mystery solved by the reply: In the Manage panel when you see SELECT * FROM table the real query executed is SELECT rowid FROM table and then a SELECT * FROM table WHERE rowid=N is execute for each visible row of the listbox. In the SQL panel query executed is just what you type On Mar 6, 2012 5:47 PM, Pete p...@mollysrevenge.com wrote: I just noticed that the same vendor that makes SQLiteManager also makes an SQLite server package (cubeSQL) that does implement MVCC. But you're right, it's definitely not there in standard SQLite. An SQLite server sounds interesting though.

So these different ways of interacting with a sqlite database might well represent an application using the sqlite API. Although when I use the Valentina VStudio SQL interface I will still see results being returned in 25 ms, compared to 500 ms going through sql yoga revdb v4rev sql valentina. This is doing a select * from a table with 22k rows (10mb in size). That's not to say that I'm outraged at 500ms. There are other steps one can take to make an interface responsive at these timescales. The Valentina guys are pretty used to comparing Livecode with the other platforms for which they provide Valentina. On 19/12/2010 Ruslan had this to say about Livecode: REALbasic - as I remember -- was very fast, near to C code...so it gives e.g. 5% overhead to pure C engine... Revolution and Director give me x4-x10 overhead I thinkRevolution because all params are packed to strings ... Director because quite complex SDK similar to MS COM ... This conclusion by Ruslan appears to be only in the discussion of calling the Valentina API, therefore one would expect that adding other layers (sql, revdb, etc.) one would see other layers adding their own torpor to the action. Does using explict transation control make any difference with sqlite? It shouldn't matter in a case where the data is only being read. I know on MVCC databases this is still a factor if one has a cursor containing the read data, as such data might still be altered from the cursor and the currency control of the MVCC requires a handle on such data to be able to maintain consistency. I can't see that it would apply to sqlite, and this site confirms that sqlite does not implement MVCC: http://www.sqliteconcepts.org/SI_index.html Bernard On Tue, Mar 6, 2012 at 5:15 PM, Pete p...@mollysrevenge.com wrote: I got the same results on the movies database and even more pronounced differences on a table in one of my own databases with ~48k records in it: SQL tab 0.519secs, Manage tab 0.045 secs, more than a 10-fold difference! Just a straight SELECT * in each case.
