To get samples and instructions for installing them:

  • On the Visual Studio Help menu, click Samples.

    For more information, see Visual Studio Samples.

  • The most recent version and complete list of samples is available online from the Visual Studio 2008 Samples page.

  • You can also locate samples on your computer's hard disk. By default, samples and a Readme file are copied into a folder under \Program Files\Visual Studio 9.0\Samples\. For Express editions of Visual Studio, all samples are located online.

To build and run this sample

  1. Open the solution file ATLMovie.sln.

  2. From the Build menu, click Build.

  3. After the sample builds, open MovieCtl.htm in your Web browser. This will play the clock.avi file, which ships with Windows.

    You may need to edit MovieCtl.htm and update the line:

    MovieCtl.FileName = "C:\Winnt\Clock.AVI"

    to point to the location of the Clock.AVI file on your particular system.
