Accessing capture device for built in webcam

Hi All

I have a VB.net 2005 windows forms application which uses webcam to take
photos of staff members etc for use within the application

All works fine if an external webcam is used

The problem I have is when clients have a laptop with built in webcam

The first time I connect to the capture drivers all works well. If I try to
take a 2nd photo I get the message Capture device does not exist

Any ideas

Regards
Steve

be sure to free up all the resources and references. Sounds like the
capture driver is still blocked from the first attempt.
