请问有没c++大佬帮忙看一下这个.idl，我想这个com的 CLSD 和IID是什么？

Question

idl文件，内容比较多，我删减了一些东西，不知道大佬可以从这里面看出哪个是 CLSD 和IID不。

Answer 1

coclass 或者 interface 的 uuid 属性里定义：

[    object,    uuid(28E68F92-8D75-11d1-8DC3-3C302A000000),  // 这就是一个 IID    helpstring("OPCServer Object"),    pointer_default(unique)]interface IOPCAutoServer : IDispatch{    // ...};

28E68F92-8D75-11d1-8DC3-3C302A000000 就是 IOPCAutoServer 接口的 IID。

CLSID，一般在 coclass 的 uuid 属性里定义：

[    uuid(860A4801-46A4-478b-A776-7F3A019369E3),  // 这就是一个 CLSID    helpstring("OPC Automation Server Activator")]coclass OPCActivator{    // ...};

860A4801-46A4-478b-A776-7F3A019369E3 就是 OPCActivator 类的 CLSID。
