CComControlBase::OnPaint

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

Always returns zero.

Remarks

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