LiveCode Forums

Bernd, Your script for finding lighter and darker versions of a color are exactly what I needed for a non-commercial project I'm working on. I'm assuming since you've posted it in a public forum that you will not object to it's reuse (in an adapted version). I would like to give you credit for the s...

Thanks Klaus, I do know the difference between constants and strings. The quotes in my message were there to separate what I typed from the surrounding text. (I should have said "without the quotes" to make it clear, sorry.) What is frustrating to me is that yesterday using tab (without quotes) did ...

I'm trying to print a field using the revPrintText command because I want to place a centered page number in the footer of the page, but I am having trouble getting the page number centered. The following command, currently part of a mouseUp handler for a button on the card with the field I want to ...

Thanks SparkOut,

As usual, there's more than one way to do most anything in LiveCode. Glad to have another approach to solve this problem.

Thanks for the quick reply. As you said, it does work in the message box without the parens. This is the sort of thing that drives us beginners crazy. Here's a direct quote from the User Guide: Tip: The Message Box is one of the more useful components in LiveCode when you are starting out and wantin...

I've created a one card stack ,with one field on it, to test printing from a field. The field is named "Info" and contains styled text such as tabs stops, bold type, and various colors of type. The field prints perfectly when I use the revPrintField command from the message box. However, I want to a...

mwieder, Yes, you're no doubt right -- as long as you are comfortable working with arrays. For my part, I haven't had occasion to work much with arrays (although it's on my list), so in this case since I only need to use the "do" command a couple of times, it's simpler to do that than trying to mast...

Thanks guys for the quick responses (as usual). Richard, you're probably right about using arrays, except in this case I only need to do this a couple of times, so I think Klause's solution is easiest for my situation. For the benifit of anyone else might want to do this: There was a small typo in t...

If I have the name of a global stored in a variable (for example, a local variable, tName, contains "gTest" which is the name of a declared global in my stack), is there some command (or perhaps function that I could write) that would allow me to store info in the global by referring to it using the...

Thanks guys, I sometimes forget that things work differently in a standalone than in LiveCode. Since the stack will ultimately be a standalone, there will not be a problem with the backdrop there, so I won't let the momentary display of the user's preferred backdrop while still in LiveCode give me a...

I'm doing it just the way Sturgis suggested above: I save the current backdrop and then change the backdrop color -- from a handler called in the preOpenStack script. That call is the first line in the preOpenStack handler. I wouldn't know how to change the backdrop color before displaying it. That'...

Thanks very much for the explanation. That does the trick, although I don't understand why it's necessary to do this in such a roundabout way. There is one small problem left that I'm not sure will have a solution: When I open the stack by double-clicking it's icon, LiveCode opens for a brief moment...

Thanks for your quick response. Not sure the best way to see if the handlers fire. What I did was place a line of code at the start of the preOpenStack handler that says: put "START" and a second line at the end of the handler that says: put " FINISH" after msg When I opened the stack from the deskt...

When a user opens my stack, I want to preserve whatever backdrop the user is currently using and then change it to my preference for a backdrop while my stack is running. Then when stack closes, I restore the backdrop to the user's original setting. I currently use the following code when my stack o...

So, it appears that it's time to take the rest of our dialog off the forum (I can hear cheers everywhere -- smile). It used to be possible on some of the boards in the forum to switch to what was called "private messages" (which I believe is still mentioned when you sign up for the forum). Some time...
