Hello.  I am relatively new to .NET, but have been tasked with
creating a bridge program for communicating with a PINPad across a
VPN.  I have successfully tested the program on my development
computer.  However, when I moved the application to a test computer,
it no longer works.  It keeps generating a COM Exception (catastrophic
error) whenever I try to call a method belonging to the COM (ActiveX)
object.
     Here is the weird part (to me).  After quickly reading some
posts, I came across similar issues that were resolved by placing the
ActiveX control directly on the form instead of instantiating it from
code.  So, I tried this and it worked on the test computer.  The
program was no longer generating the COM exception.
     My question is why?  Why would it work correctly without the
control on the form on one computer and not the other?  Both the
development and test computers have the latest version of the
framework and both are Vista Business edition computers.  Any ideas
would be most appreciated.

Vincent
