Hosting a Windows Form User Control in an MFC Dialog Box
MFC hosts a Windows Forms control as a special kind of ActiveX control and communicates with the control by using ActiveX interfaces, and properties and methods of the Control class. We recommend that you use .NET Framework properties and methods to operate on the control.
For a sample application that shows Windows Forms used with MFC, see MFC and Windows Forms Integration.
In the current release, a CDialogBar object cannot host Windows Forms controls.
