Provides the basic functionality for hosting of a Windows Forms control.
The CWinFormsControl class provides the basic functionality for hosting of a Windows Forms control.
For more information on using Windows Forms, see Using a Windows Form User Control in MFC.
Your MFC code should not cache Window handles (usually stored in m_hWnd). Some Windows Forms control properties require that the underlying Win32 Window be destroyed and recreated using DestroyWindow and CreateWindow. The MFC Windows Forms implementation handles the Destroy and Create events of the controls to update the m_hWnd member.
MFC Windows Forms integration works only in projects which link dynamically with MFC (in which AFXDLL is defined).
