how to call other exe file in Eprime?

[chen]

Thank you!
 
I copyed the declare syntax to user script window (without "public" before "declare") and in an inline object used the ShellExecute function. But it seem Eprime just skiped this function. No error, but just ignore this function. The same script works well in VB.
 
Why I have to use external function is I have a special device, it not only used as response switch, but also used as a signal generator, I used VB script not only detact a key press but also receive a signal from the device. VB script fulfill this by calling an executive function. Since eprime is very good at timing, I want to write script using Eprime, but also need to use my old device. So I hope I can call that executive function in Eprime.
"ShellExecute" is a dll file I used to call that executive function in VB, If you can help me to find some way to call an executive function, i do not need to use ShellExecute. Or can you give me an Eprime example of use external function?
 
Thank you very much!

Have you just tried this in E-Prime?  This looks very much like what 
I did several years ago to get direct access to the Windows API in 
order to use some extra keyboard functions (that was before I learned 
that I could do the same thing by testing for key offsets <g>).

The whole "Public Declare ..." stuff works just like in VB, of course 
you have to put your .dll file in the right place, etc.  But I don't 
know anything about ShellExecute, perhaps that is where you're getting stuck.

Is there some compelling reason that you need to call external 
executables instead of just making your whole experiment work in "the 
E-Prime" way?
