Thank you all for your quick help and suggestions! Unfortunately, I don't
have the source code for the exe that is being called by the C# program, so
am unable to debug it (to set some exit codes - this exe is an old pgm and
doesn't return any return codes).
However, a co-worker pointed out the problem in this case - turns out that
because I was using the windows scheduler to schedule this C# program after
RDP'ing into the server, and was logging off (rather than disconnecting), the
process didn't work. Apparently, the called exe needs the user to be logged
on. Anyway, if I disconnect from my RDP session (instead of logging off), the
process works fine and the data gets pulled into the DBF file!
Thanks for your suggestions though - I'm sure I will get to use them for
other problems that I face in the future!
