 WM_ENTERSIZEMOVE

The WM_ENTERSIZEMOVE message is sent one time to a window after it enters the moving or sizing modal loop. The window enters the moving or sizing modal loop when the user clicks the window's title bar or sizing border, or when the window passes the WM_SYSCOMMAND message to the DefWindowProc function and the wParam parameter of the message specifies the SC_MOVE or SC_SIZE value. The operation is complete when DefWindowProc returns.

The system sends the WM_ENTERSIZEMOVE message regardless of whether the dragging of full windows is enabled.

A window receives this message through its WindowProc function.
