来人帮忙啊

#import "xxx.tlb" no_namespace named_guids //命名规则：接口Ptr p((__uuidof(类))) MyCom_InterfacePtr p(__uuidof(Button)); p->Add(xxx,xxx);

引用 2 楼 孤客天涯 的回复:

#import "xxx.tlb" no_namespace named_guids //命名规则：接口Ptr p((__uuidof(类))) MyCom_InterfacePtr p(__uuidof(Button)); p->Add(xxx,xxx);

现在需要使用连接点 来接收这些委托 ，该怎么写

照着网上例子写的 ,hr 一直返回S_OK, 但调用add时就会出错

c#可以传回调，可以自己定义个callback，为啥一定要连接点通过这样的方式？
