Mouse Scrolling Wheel activation in EPrime?

[David McFarlane]

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 (although current 
estimates are more like 10 days) -- 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...

AFAIK scrolling wheel support must be built into the application, and 
I do not see PST doing that for E-Prime.  Then again, maybe you could 
do this by calling the appropriate Windows API, but that is not a job 
for beginners.

For continuous collection of mouse data, please see the MouseDevice 
topic in the online E-Basic Help, and look through the example 
programs that you may download from the PST web site.  I do not think 
they have one that does exactly what you want, but they do have 
programs that will show all the necessary techniques that you may 
then put together.  I have actually seen a demo of exactly what you 
want, so I know that EP can handle this well.
