Didn't I see this post twice yesterday? Where are you getting these header files from? You need the DirectShow SDK. It's part of the platform SDK. Once you've installed that, make sure your build environment is setup properly. This is explained in the documentation: Setting Up the Build Environment[^] ICaptureGraphBuilder2 is defined in strmif.h, which is included by dshow.h. Compiler errors really should be the least of your problems when using DirectShow.

I would create a new one with the wizard. If you're on Visual C++ 6.0, I'm not sure what issues you'll have. You may want to post a question to 6.0 users about using the latest platform SDK with that version of C++. Your project settings and build environment settings need to be solid for any Windows project, especially when using DirectShow, DirectX, etc. Mark Mark Salsbery Microsoft MVP - Visual C++ This episode brought to you by the number 3 Change BAR Color of CProgressCtrl CodeMak11-Jul-07 23:47 CodeMak 11-Jul-07 23:47  Can anyone help me please to change the bar color of an XP styled CProgressCtrl please...
