Using MCI Command Strings

[The feature associated with this page, MCI, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of MCI, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This section contains examples demonstrating how to use the MCI command-string interface to perform the following tasks:

• Sending a Command
• Opening Multiple AVI Files
• Changing the Playback State
• Converting Strings
