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?

Please take a look at the new sample I added, ModalShellExecute.es.
This method will work for some applications. The file suspends E-
Prime, opens Notepad, and then resumes the experiment once Notepad is
closed. You will simply need to replace Notepad with the application
you desire.
In general, many of our users have been able to use this sample to run
various applications, but specific testing by PST for applications
other than Notepad has not been performed. Keep in mind that
additional programming may be required to allow the following sample
to work with the external application you want to use.

If you only need to read a digital signal from the device, why not
just use E-Prime's built-in "ReadPort()" function? You had to use an
external .exe in VB because VB does not provide any functions to read
from or write to arbitrary I/O ports, but one of the virtues of
E-Prime is that this ability is already built in with the added
ReadPort() and WritePort methods. You might want to give that a try.

communications with the USB bus. However, E-Prime can call into DLL
functions and can use the CreateObject API to attach to some COM
objects. The best advice we can give you, if you choose to use the
DLL- faciliated USB connection, is to refer to the Declare statement
in E-Basic Help. Before attempting to do this, however, we stress that
even if communication can be obtained, we worry about the accuracy of
the timing for what you will receive. This would, however, at least
allow you to communicate with the device without using an external
application.
If the device is recognized as a serial device in Windows, you can use
E-Prime's built-in serial port communication functions.

Sadly, Google Groups ended its file libraries many years ago, so you
will not find ModalShellExecute.es or any other example files here
anymore. But you may still find useful examples at the PST Support
website (as well as at STEP). I think that the "Suspend/Resume
experiment" at the PST Support site may show what you are looking for.
