I suggest you go to lectures, learn what you were taught to learn and code it off your own back. I had to learn C# for a work project, and had considerably less than 12 weeks!

Part of your course is learning this yourself - NOT asking others to do your homework.

Take a look into the ActiveMovie Quartz library, it might help. Its part of DirectShow

Play a sound file with quartz.dll

Play a video file with quartz.dll

The source you find on codeproject should be zipped up (.zip). Windows already can open zip files or you can use 7zip,winrar, etc... unzip the files anywhere and you should see a folder, .sln file, or a csproj file, double click the .sln or csproj to open it up in VS2005.
