If you have IDL5.5 I encourage you to try the new COM/ActiveX interface.
The only help you get from RSI is found in the "What's new in 55" pdf. Not
as much as one would like but enough to start doing some damage.
You'll need OLEview (available free from MS), some good documentation on the
camera side and some luck but in theory I think it should do the trick. It
will also help if you have the activeX control test container which ships
with Visual Studio. I have had mixed luck, but most of the bad luck was due
to non-existent documentation on the ActiveX control side.
Using OLEview, find your activeX control (maybe under automation objects).
Use OLEview to get the CLSID (required by IDL). If you have the activeX
control container use "Insert new control..." to create an instance of your
camera control. Then you can use the "invoke methods" dialog to explore the
methods. If you don't have the AX control container you can use OLEview to
get some basic into on the methods by using the TypeInfo viewer. Hopefully
the methods will be documented so this exercise will be academic.
At this point my experience with these two tools starts to wane so I go back
to IDL and start experimenting. Check out the examples in "what's new"
It would be helpful if you could report back to the group with your results
(or just to me if you are shy). Your experiences, bad or good, with the new
COM objects will help the 3 other IDL users who are trying to use them. :)
