Rick-
Thanks for the response, I do have IDL 5.5 and I reviewed the what's
new manual. It all looks very interesting. I don't have any
experience with COM object or ActiveX (or IDL just yet), however I
know it would be a very useful thing to learn.
I did figure out a way to use the camera by just using vbscipt,
running the script with the spawn command, and just using IDL to
modify the text in the script file to edit parameters. This is
cheating though...but works.
I think i'll spend some time investgating the method you outlined
since I'm up for learning something...
Thanks!
