If you are a novice IDL user, I seriously doubt you
are programming iTools. So I don't think IDLitIMessaging
is what you want. :-)
Why don't you try something a great deal simpler. Here
is a simple pop-up dialog that does what you want:
http://www.dfanning.com/programs/textbox.pro
You use it like this:
answer = TextBox(Label='What is your favorite color?', $
Title='Type your favorite color', Cancel=cancelled)
IF cancelled THEN RETURN
You can read more about how it is created here:
