So true Gregory. Michael On Oct 3, 2010, at 12:16 PM, Gregory Lypny wrote: But the documentation problem, both with the user guide and built-in help or dictionary, goes far beyond updating. Good writing, examples, organization, and consistency in design take time. If you type the word Array into the built-in help, the only hits you will get is for ArrayEncode and ArrayDecode but nothing for an array itself. Someone new to LiveCode, who perhaps coincidentally got far enough into the user guide to come across arrays, would be hard-pressed to get any information about their uses or properties. A benchmark for good documentation in my mind is the original HyperCard User Guide and HyperCard Reference Manual. The writing is clean and the example code statements and handler snippets are carefully chosen to give the fullest scope of usage of the item in question. Another is Mathematica's built-in documentation (and even their online documentation), where what they lack in Apple's writing and publishing suave, they make up for in comprehensiveness.

Re: snapshot and background problems
So when I do something like set the filename of image Image to filepath that data is 'the text of the image or just 'the image' which backs the image in its original format. When I ask for 'the imagedata of the image' I get four bytes for each pixel in the image: one byte of zeroes, a byte representing red, blue and green. There is also an alphadata which has a byte of alphadata for each pixel in the image. This data is a serialized stream which representing in sequence the data : left top pixel ... right top pixel, left pixel of the second row ... right pixel of second, left pixel of third row ... right bottom pixel. In a sense the imagedata has alphadata information set to zero (no transparency). How do I put the image in an image into a variable or property? Michael On Jun 28, 2010, at 1:53 PM, J. Landman Gay wrote: Scott Rossi wrote: I have no data to suggest that setting the text of an image is any better or worse than the method of putting image-related data into an image. I've only seen references by the programming dudes at RunRev to use the text property, so I do. They're different properties for different purposes. The imagedata is basically just a screen shot and if you set the imagedata of an image object, what you end up with is just a bitmap. All other binary info is lost, including channel data. If you set the imagedata of an image object that isn't exactly the same size as the original screen shot, the image will corrupt and become unrecognizable. The imagedata must match the size of the image object exactly to display properly. (Once it's set correctly, you can then scale it, but it will look terrible.) Setting the text of an image (or just putting an image reference into an image object, it's the same thing) stores all the binary data, including the alpha channel, and the image is scalable and can be manipulated in lots of ways. The size of the image object does not need to match anything in particular, since the engine will scale the data as needed. Imagedata is useful for creating thumbnails, for example, or for reducing the size footprint of an image in the stack when you know you'll never need to change the displayed bitmap. You can reduce the size of the image internally substantially by using imagedata. Setting the text of an image is more useful if you want to retain all the image properties and manipulate it (rotate, scale, etc.) -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Use the dateItem format of the date: Convert your date to date items. convert myDate to dateItems Now add your time increments to the appropriate item add 17 to item 5 of myDate -- hours add 3 to item 4 of myDate -- days Then convert to dateItems again convert myDate to dateItems Convert back to the date format you were using To increment by weeks just add or subtract 7 days, item 3 of the dateItems. To increment by months just add the number of months to item 2 of the dateItems. Your February problem will be taken care of automatically if you are incrementing by the number of months. Use seconds only when you want to know how many days are between two dates. put (dateInSeconds1-dateInSeconds2)/(86400) into theDaysInBetween Using item 7 of the dateItems allows you to calculate dates such as 'the second Monday of March.'

Re: Random #s
If you are asking the random of a big number then that will be true.
I think I remember that to generate a list of random numbers what you
should be doing is asking questions like
random(N)
random(N-1)
.
.
.
1
If you wanted to generate a random list with the numbers 1 thru 10
random(10) - 3
Now you pick the 3rd item of the list of integers{1,2,3,4,5,6,7,8,9,10}
you pick 3 and remove the 3rd item.
Your random list is {3}
random(9)-3
Now you pick the 3rd item of the remaining integers
{1,2,4,5,6,7,8,9,10}: you pick 4 and remove the 3rd item.
Your random list is {3,4}
And so on.

Apparently he made a suggestion to Scott Raney about ways to optimize operations in which a string of a given length is used to replace a substring of the same length within a larger chunk. In previous versions a very generalized approach was used for all replacement operations, requiring that the data be copied during the replacement, which can be computationally expensive with large chunks. Since the data being inserted is the same length as the data being removed the handle size doesn't change, allowing the operation to work in-place, without copying. IIRC, Raney reported that the new method should improve speed by roughly 4000 times for those cases. Dar - got the details for us?

Re: Date Troubles
The date formats only works over a short period of time, about 2^32 seconds (4 byte word). That is about 1934 to 2035. If you are using dates outside of that region then you need to work with dateItems and seconds. I think dateItems gives you the largest time span. To do this you have to convert your date to a dateItem with your own handler, not the convert function: put 7/18/1868 into theDate put myDateItemHandler(theDate) into theDate function myDateItemHandler theDate get the itemDelimiter -- this get/set may not be needed set the itemDelimiter to / put item 1 of theDate into theMonth put item 2 of theDate into theDay put item 3 of theDate into theYear set the itemDelimiter to it-- this get/set may not be needed return theYearcommatheMonthcommatheDaycommacommacommacomma end myDateItemHandler You can convert this dateItem to seconds and do your calculations. If you want to return a date convert your seconds to dateItems and write a handler which creates your desired date format.

Re: Why no closeField messages sent?

In fact a put into the fld can stifle the closeField message. Make a card with two flds. In fld 1 on keyDown theKey if theKey is r then put rule after fld 1 exit keyDown else pass keyDown end if end keyDown In the card's script trap the closeField message on closeField beep end closeField Now type 'dogsrtab' (where tab is the tab key). No beep even though the user has clicked and typed in the field. But you can type 'dogsrtheworldtab' and get a closeField to fire off.

In many cases this is true. But think about the case where you are scanning identical items. It would nice to be able to type 10 and then scan the item instead of scanning each identical item. Suppose you want to route the item somewhere. You need to be able to enter the routing information. How about using a scanner to log in? You would probably want to type a password. If you just want to scan an item and then go to the next item and scan it, then not being able to tell where the input is from is fine. But in all the other cases you probably just want the scanned information going to a specific field (container) and it would be nice not to have to force the focus to that field with an addition mouseclick or tab(s) etc. Michael On Nov 27, 2004, at 10:48 AM, Frank D.

Paths to inside bundles [was Re: A clue for using Valentina by XCMD]
When I say a stack I mean a stack.

If I tell the standalone to put the externals in fld 2 I see ./VXCMD_Macho_MC Untitled 2.app/Contents/MacOS/externals/revdb.bundle This isn't where Rev puts the Xcmd. The path to the Xcmd in the bundle is ./Contents/MacOS/externals/database_drivers/VXCMD_macho/Contents// MacOS/VXCMD_macho I explicitly set 'the externals' to this path in the stack before I make it into a standalone application. But that doesn't work. I can put the Xcmd in the folder with the standalone outside of the bundle, set the externals to this location and after a couple of launches of the standalone, it sees the Xcmd. But I can't get the standalone to see the Xcmd in the bundle. The Rev Docs lead me to beleive I should be able to use pathnames such as the one above. Is this the correct pathname? In general, how does one put things in the bundle.? And where? Michael On Jun 21, 2004, at 5:28 PM, Robert Brenstein wrote: guess that by creating the stack you really mean creating a standalone.

Re: A clue for using Valentina by XCMD
Are you using Windows or OSX. If you are I think you might need to type in the message box of the stack you are using set the externals of this stack to ./VXCMD_Macho_MC so that the stack knows to use the Xcmd (p 4 of the VXCMD docs). You have to quit Rev or purge the stack from memory and then start afresh before the property is registered. If your file path or Xcmd is different then modify the set command accordingly. I think the macho version doesn't ship with OSX Rev so you will need to download it from Paridigmasoft.com. I don't know about windows but I think you need VXCMD_Win_MC.dll. That is what the docs say. If you get the externals set to your stack you should be able to type put valentina(version) into the message box and have the version returned.

Re: BUG in CONVERT command - or I can't tell the time
When it is 12 midnight in Edinburgh (GMT) it is 6:00 PM the day before here in Dallas (CST) (no daylight savings time). And that is the way it should be. If a child was born at zero seconds, okay 1 second, in Edinburgh a year later in Dallas at 6:00:01 PM on Dec 31st she would be a year old. IMO, date and time formats should only be used to display dates and times. Aside from formatting issues, as illustrated here time and date formats have 'hidden parameters' such as where (time zone) and when (daylight savings time) associated with them. If you use time and date formats to to calculate time differences you will find several glitches in your calculations. Daylight savings time can add and subtract an hour and even give you a negative time (which can be particularly troublesome). Using the additional 'system' parameter doesn't solve these problems.

Re: MOD function does not work! So be warned!
Actually the answer to my question is that there is no such thing as an integer in xTalk. Any string which could be a number which seems to act like an integer is a binary real which has an exact decimal representation during computation. You can't define a range for an integer if your language does not have the concept of type. What I was trying to say is that an integer to a lot of people is a whole number in the range of +/- infinity. If they add zero to a large integer and the result is another large integer they are upset. Just like those people who summed ten tenths and didn't get one. This isn't a large problem in the since that most xTalk programmers aren't going to be writing programs where they will encounter these situations. The large problem I see is if an xTalk were ones first language one would be ignorant of computer numerics. michael Rob Cozens of [EMAIL PROTECTED] wrote the following on 4/6/02 10:32 AM One problem is what is an integer?

The engine which drives the engine is a binary machine. Is one one, 1 or 1.0? It depends upon the context. What this means in effect is that the rules for typing in xTalk are more complex than the rules for typing in a 'typed' language. 99.9 and maybe a few more 9s of the time this doesn't matter or the automatic typing rules work the way we think they should. xTalk scripters are a prior ill equipped to deal with numbers. When HyperTalk became PPC native, the precision to which numbers were calculated decreased by two or three orders of magnitude. And as you point out, where in any xTalk documentation does anyone talk about numbers. Only the HyperCard documentation talks about SANE and number precision.

I use revShowPrintDialog true,true and I can cancel the printing if I select Cancel during page setup but if I click Cancel during dialog the job still prints. Also, how persistent and what is the scope of the showPageSetup and showPrint parameters of revShowPrintDialog? When I comment out the rSPD command, the last sPS and sP parameters used are still in effect. Thanks, michael ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
