D'oh! I told you it was something stupid I was doing.

Thanks for the kick in the head.

Shawn,
GetAvailableDevices is a method, you should be calling it.
I.e.
for r in QuickCam.GetAvailableDevices(): print r

I am trying to use the QuickCamLib library with Python.net. I looks like
I'm not getting the .net library loaded right, but I'm new to Python.net and
to .net in general, so I'm not sure I'm doing everything right.
The quickcamlib is here: http://grazz.com/projects/quickcamlib
Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

QuickCam.GetAvailableDevices

for r in QuickCam.GetAvailableDevices: print r

File "<pyshell#6>", line 1, in <module>
for r in QuickCam.GetAvailableDevices: print r
TypeError: 'MethodBinding' object is not iterable

from System.Drawing import Point
p = Point(5,5)
print p

{X=5,Y=5}
(the "Point" stuff is there to show that Python.net seems to work for some
objects, just not others)
The 'unbound method' message is worrisome. Seems to me it should have
done something instead of just complain that it is unbound. Lazy binding
isn't usually this lazy :)
I don't know enough about .net to really test this library any other way,
so it is also possible the library is dorked up somehow.
If I need to send more/different data, please let me know. Like I said,
I'm new at a lot of this, so I'm likely missing something simple.
Thanks in advance.
