"Access is unable to save the WIA
Video Preview Class object because it does not support
persistence, or your computer may have run out of disk

Lots of space left.

Trying to let the user set up a shot. USB Camera in a laptop; I can get the camera to take a shot, but not preview !

I have an an old exe that previews and takes shots, so I know the camera supports it.

All 3rd party OCX vid/photo add on's fail too in video preview.
The old exe I have with source was compiled in an old version of Visual Studio with direct x, and will not compile in VS2010.
