Provides access to properties and methods exposed by an object.
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 CBaseBasicVideo::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
- Flags describing the context of the CBaseBasicVideo::Invokecall.
- pdispparams
- Pointer to a structure containing an array of arguments, an array of argument dispatch IDs for named arguments, and counts for number of elements in the arrays.
- pvarResult
- Pointer to where the result is to be stored, or NULL if the caller expects no result.
- pexcepinfo
- Pointer to a structure containing exception information.
- puArgErr
- Index of the first argument, within the
rgvargarray, that has an error.
Return Values
Returns DISP_E_UNKNOWNINTERFACE if riidis not IID_NULL. Returns one of the error codes from CBaseBasicVideo::GetTypeInfoif the call fails. Otherwise, returns the HRESULTfrom the call to IDispatch::Invoke.
