Actually like the "ImageCapture" application of the SDK sample programs.

The Sample Grabber is a transform filter, so the output pin must be connected to another filter. The code snippet looks like this: ... it's interesting though, 'cause I can then go on to do this: ----------------------------- unsigned char *pBuffer = new unsigned char[cbBuffer]; if (!pBuffer) { // error out memory } hr = With the passing of Thai King Bhumibol, are there any customs/etiquette as a traveler I should be aware of?

Create the Sample Grabber filter, add it to the graph, and query for the ISampleGrabber (ISampleGrabber *m_pGrabber). // Create the Sample Grabber. Right :) I just removed all the error checking to make it shorter and easier to read. Often, you may simply want to discard the samples after you are done with them. For example, if the "hr = pControl->Run()" line fails for some reason, the code will plough on.
