Input object property

[David McFarlane]

Evelina,

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
takes any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they 
strive to respond to all requests in 24-48 hours -- this is pretty 
much their substitute for proper documentation, so make full use of 
it.  3) If you do get an answer from PST Web Support, please extend 
the courtesy of posting their reply back here for the sake of others.

That said, here is my take...

As I understand it, you want to enter a color as text or numbers 
during runtime, and then use that color for some text on a 
Slide.  Not sure why you want to do this (there is probably an better 
way to achieve your ultimate end), but here are my thoughts.

First, the MsgBox() function does not work for inputting text, it 
takes only button responses.  For text input you will need to use 
either InputBox$() or AskBox$() -- see those topics in the E-Basic 
Help facility.  You may then use the input text to set a color.  You 
may use some well-known color names, or RGB values -- I don't know 
where this is documented, I had to use Find in the E-Basic Help with 
"color" or "rgb" to find some glancing documentation in topics such 
as StimDisplay.ForeColor.  Anyway, it looks like you may indeed use 
strings such as "255,255,255" for RGB values.

I would pass on the value through an attribute reference.  So, 
sometime before my Slide, I would have inline code such as

c.SetAttrib "ForeColor", InputBox$("Enter color:")

Then, for the text sub-object on my Slide, I would set its ForeColor 
property to "[ForeColor]".  That would do it (I know, because I just 
tried this out and it worked).  Of course, make sure to set the color 
attribute at a high enough Context level -- for more on this see 
Chapter 4 of the User's Guide that came with E-Prime.


Finally are a few general suggestions about using InLines:

(1) Work through Chapter 4 of the User's Guide that came with E-Prime.

(2) If you don't already have some computer programming experience, 
then take a course on Introduction to Computer Programming.

(3) Work through the book "VBA for Dummies".
