Remarks

When you host a user control in an MFC View, CWinFormsView Class routes commands and update command UI messages to the user control to allow it to handle MFC commands (for example, frame menu items and toolbar buttons). By implementing ICommandTarget Interface, you give the user control a reference to the ICommandSource object.

See How to: Add Command Routing to the Windows Forms Control for an example of how to use ICommandTarget.

For more information on using Windows Forms, see Using a Windows Form User Control in MFC.
