Call System::AutoCmd::GetCallType to determine the type of flag needed to call the method represented by System::AutoCmd::AutoCmd using the IDispatch::Invoke method of the Automation interface. System::AutoCmd::GetCallType returns DISPATCH_PROPERTYGET if the System::AutoCmd::AutoCmd object represents a property getter, DISPATCH_PROPERTYSET if it represents a property setter, and DISPATCH_METHOD if it represents any other method type. 

System::AutoCmd::GetCallType is declared as a pure virtual method. Descendant classes, which represent specific types of interface methods, override this method to return the appropriate value.
