Cool. I'm actually impressed at how easy it is (never done this before). If you've never remoted anything with MSRPC it can be a frustrating experience.

Further notes: the geometry parameter (1024x768+0-0) can be replaced with NULL. I didn't realize this until after I sent it. Also, if the VEE function call fails (vrpcCallAndReceive) then the In parameter is left hanging (i.e.
it leaks). Technically it's not a big deal because it gets cleaned up automatically, but it's still bad form.

Sorry, no. Er, not at the moment. I'll see if I can whip up something quick.

Well they're using different methods. The C version is using VEE's RPC API &
the other versions (C++ & VB) are using the control. You can use the control
in C too, but it ain't pretty.

All,
Â
Does anyone have a simple example of how to call a VEE function from C (not C++)? I want to pass an integer to the function and get back a multi-dimensional array.
Â
The Agilent C example (callVEE.c)Â seems far more complicated than the VB example (CallVEE.frm). Is it really that much more difficult in C?
Â
Bill
