MAKE_DELEGATE

 

Attaches an event handler to a managed control.

Syntax

MAKE_DELEGATE( 
   DELEGATE,
   MEMBER
);

Parameters

  • DELEGATE
    The type of the managed event handler delegate, such as EventHandler.

  • MEMBER
    The name of the event handler method to be attached to the control.

Remarks

This macro creates a managed event handler delegate of type DELEGATE and of the name MEMBER. The managed event handler delegate allows a native class to handle managed events.

Example

The following code example shows how to call MAKE_DELEGATE to attach an OnClick event handler to an MFC control MyControl. For a broader explanation of how this macro works in an MFC application, see How to: Sink Windows Forms Events from Native C++ Classes.

// CMyView derives from CWinFormsView.
void CMyView::OnInitialUpdate()
{
   CWinFormsView::OnInitialUpdate();

   GetControl()->Click += MAKE_DELEGATE(System::EventHandler, OnClick);
}
