CBaseControlWindow::put_MessageDrain

The put_MessageDrain method sets the window to receive window messages sent to the video renderer.

Syntax

  HRESULT put_MessageDrain(
    OAHWND Drain
);

Parameters

Drain

Window to post messages to.

Return Value

Returns an HRESULT value.

Remarks

Messages sent to the video renderer filter can be posted to another window. This member function registers the window to receive these messages. Unlike the CBaseControlWindow::put_Owner member function, this member function does not make the video window a child of another window. It is particularly useful for full-screen video renderers, which cannot be child windows.

Requirements

**  Header:** Declared in Ctlutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
