HRESULT Invoke( DISPID dispidMember , REFIID riid , LCID lcid , WORD wFlags , DISPPARAMS * pdispparams , VARIANT * pvarResult , EXCEPINFO * pexcepinfo , UINT * puArgErr );
Parameters
- dispidMember
- Identifier of the member. Use CMediaEvent::GetIDsOfNamesor the object's documentation to obtain the dispatch identifier.
- riid
- Reserved for future use. Must be IID_NULL.
- lcid
- Locale context in which to interpret arguments.
- wFlags
