Hi Adrian,
I've had some success connecting IDL to a Logitech WebCam using their API
and the new IDL ActiveX widgets. To get the images into IDL, you either have
to use file transfer (ugly and slow, but very simple:-) or do some fancy
footwork with C++. Whilst doing a search the other day I noticed an API that
claimed to connect to any webcam from C++, so you might be able to do the
same thing with another brand of camera.
I have also written a serial port program for one of my customers in C++. I
used an excellent tool called UserPort (you will need this if you are on
WinNT, 2000 or XP) and created a DLL using MSVC++6.0. This was simply called
from IDL using CALL_EXTERNAL (which I put into a wrapper routine).
I hope this is useful. Let me know if you need any more details.
Cheers,
Dave
