The while (!stopSignal.WaitOne(0, true)) { Thread.Sleep(10); } loop in CapDevice.captureImage could be replaced by a single call to stopSignal.WaitOne(); Then you won't get a ThreadAbortException either when CapDevice.Stop calls worker.Abort(). I don't think calling worker.Abort (unconditionally) is necessary. This call also prevents execution of control.StopWhenReady(); My 2nd, much less important, remark is that I would keep the variables graph, grabber, sourceObject, grabberObject, control, map and section of CapDevice should all local to the captureImage function.

The webcam is connected via USB and I can get it working with a DirectShow control for WinForms, but really need it in WPF without just wrapping up the WinForms control. Any ideas why this would be black? I have checked that it is setting to the correct device. Please help! Hi there, I have tried this sample but the box just comes up black.
