I am looking for a self contained simple example that demonstrates how the Code Project shows a Collapse Expand section for code snippets. Anybody willing to share it with me?

If you do not understand C, then you are in a world of hurt with DirectShow. It requires a very solid understanding of C and COM. It also requires a good deal of persistence and savy just to get the Examples up and running cleanly. If you want to start a very long trek of learning, here you go: [1] You need to download the Platform SDK (e.g., I have PSDK-x86.exe). [2] You need to download the DirectX SDK (e.g., I have dxsdk_feb2007.exe). After doing [1] and [2] you should read the "Graphics and Multimedia > Direct Show" section from the Platform SDK Help. That is about a good an intro to Direct Show you will find; I don't know of a single reference that does more than re-iterate this intro. After that you should try to get the Examples working. If you make this far, then post again and I'll advise further. Hoss Fly
