Description
Invoke performs a call to a late-binded property or method.
Invoke actually calls a method or a property exposed by the COM object through IDispatch. Invoke requires a previously obtained dispatch identifier. The identifier uniquely identifies a method, a property, and a list of parameters to be passed to the called method and exception information. The dispatch identifier of a method or property (also known as dispid) can be obtained by a calling the GetIDsOfNames method.
