CBaseBasicVideo::Invoke

The Invoke method provides access to properties and methods exposed by an object.

Syntax

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::GetIDsOfNames or 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::Invoke call.

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

Pointer to the index of the first argument, within the rgvarg array, that has an error.

Return Value

Returns DISP_E_UNKNOWNINTERFACE if riid is not IID_NULL. Returns one of the error codes from CBaseBasicVideo::GetTypeInfo if the call fails. Otherwise, returns the HRESULT from the call to IDispatch::Invoke.
