Perfect, thanks.
I totally forgot about the url keyword. Not particularly intuitive.
Appreciate it...

All I want to do is open a text file and display it in a text field, modify it, then save it again. I can use the Answer command, but that gives me the path. How do I get the contents of the file? I've used Live code a long time ago (RunRev era), but the new dictionary is perplexing to me, and I can...

Hey, I'm interested in controlling the properties of text as it is being entered into a field. Specifically, I'm making a chemistry application and need to distinguish numbers and letters, then would like to make all the numbers to be subscript as I type them in. The following code works but is a bi...

I'm not sure how to insure a certain number of significant digits in a number I'm diplaying. As an example, I perform a calculation and get a number: 35.003742. If I use statRound(35.003742,2) I get 35 (written without any decimal point). Not 35.00. How to I get "35.00"? Is there another function th...

Craig, Thanks for the snippet. I wonder if we are pretty much doing the same thing. Of course, I have to enforce some restrictions on input (must start with a letter, every element must only contain two letters but integers can have any number). I'm not worried about the error catching code just yet...

Hi, I've been working on a short program that calculates the formula weight of a given molecular formula. Conceptually it is very easy, and I've done the same thing using Java and Python, but as practice I'm trying to use LiveCode to do the same thing. Input is a formula like: "C6H5Cl1". In the past...

Thanks for the response.

It turns out to be very simple once I know where to look.

Hi again, actually, I don't think I was perfectly clear with my earlier post. I don't want to just scroll - that happen automatically. What I want is to capture the mouse wheel as an event. There are two cases where I would like to do this. In one case, I would like to use the mouse wheel to move up...

Hi, I have a scrolling list of files (that I read from a folder) that I would like to survey quickly. I know how to make the down arrow and return key move between items in the list. Is there a way to use the mouse wheel to scroll down? Can I catch the mouse wheel change as an event? Thanks, --Doug

Thanks for the explanation, I think I understand now. My confusion was not recognizing that selectedText was a function. I assumed that any object that was made to select things (lists, popup buttons, radio groups) would have an attribute representing the selection that I could get and set. Now I se...

Hi, I have an array that I'm using to store comments about various image files. I am now trying to search the comments for keywords, and when I find hits, create a list and display the image and comments. Below is an excerpt of my code: on mouseUp set the itemDelimiter to return put the text of fiel...

Thanks Klaus, Works great. My rename code now looks like: on mouseUp put the fileName of image "image" into tOldName set itemDelimiter to "." put tOldName into tNewName ask "New Name:" put it into item 1 of tNewName rename file tOldName to (defaultFolder & "\" & tNewName) send "openstack" to stack "...

Hi, I have an image control that I load from a file on disk. I would like to change the name of the image, and have it change the name of the file on disk. Is there an easy way to do this?
Thanks,

How do you keep track of changes in Rev? I frequently save different versions with a different name, but my stacks continue to have the same names so that my scripts all work. However, when I launch a different version of a project, Rev complains that several stacks have the same names. Do I have to...

Perfect. That's exactly what I need. I never would have thought about looking up that.

thanks,
