IDL文件

import "oaidl.idl";import "ocidl.idl";[object,uuid(B325C169-61FA-4513-9DB1-0CC231CCB633),dual,nonextensible,helpstring("IComTestClass Interface"),pointer_default(unique)]interface IComTestClass : IDispatch{[id(1), helpstring("method Method1")] HRESULT Method1(LONG arg1);};[uuid(9098C7D5-91BA-4C0C-837B-DB81C3DBA6AE),version(1.0),helpstring("ComTest 1.0 Type Library")]library ComTestLib{importlib("stdole2.tlb");[uuid(F41DAE07-8D10-430B-8834-06BB4B9AE8A2),helpstring("_IComTestClassEvents Interface")]dispinterface _IComTestClassEvents{properties:methods:[id(1), helpstring("method Event1")] HRESULT Event1(LONG arg1);};[uuid(2961361E-8E6D-4618-95A8-4DF03B65BDC3),helpstring("ComTestClass Class")]coclass ComTestClass{[default] interface IComTestClass;[default, source] dispinterface _IComTestClassEvents;};};

Method1中触发事件

STDMETHODIMP CComTestClass::Method1(LONG arg1){// TODO: Add your implementation code hereFire_Event1(arg1);return S_OK;}

win32com调用组件

import win32com.clientclass EventHandler:def OnEvent1(self, val):print(val)o = win32com.client.DispatchWithEvents("ComTest.ComTestClass", EventHandler)o.Method1(23)
