The put_Caption method sets the window title or caption.
HRESULT put_Caption( BSTR strCaption );
New window caption.
Returns an HRESULT value.
Most top-level windows on a Windows-based desktop have a title (caption) associated with them. This property can be queried and set through the IVideoWindow interface. Any caption set will be visible only if the window has the WS_CAPTION style applied. If it does not, the caption can still be set (and retrieved), although it will not be visible to the user.
