IDispatch Methods

IDispatchEx is a subclass of IDispatch – therefore, any object that supports the IDispatchEx interface also has implementations of the IDispatch methods:

These methods behave as defined by IDispatch except that they might provide additional support as defined by IDispatchEx. For example, IDispatchEx::Invoke should support the same values as IDispatchEX::InvokeEx (for example, DISPID_THIS, DISPATCH_CONSTRUCT). This allows an implementation of IDispatchEx::Invoke to simply delegate calls to IDispatchEx::InvokeEx. An object that supports both IDispatch and IDispatchEx might also choose to provide this additional support in IDispatch::Invoke.
