CComControlBase::OnPaint

  • Articolo

Prepares the container for painting, gets the control's client area, then calls the control class's OnDrawAdvanced method.

LRESULT OnPaint( 
   UINT /* nMsg */, 
   WPARAM wParam, 
   LPARAM /* lParam */, 
   BOOL& /* lResult */ 
);

Parameters

  • nMsg
    Reserved.

  • wParam
    An existing HDC.

  • lParam
    Reserved.

  • lResult
    Reserved.

Return Value

Remarks

If wParam is not NULL, OnPaint assumes it contains a valid HDC and uses it instead of CComControlBase::m_hWndCD.
