IClassFactory最重要的一个函数就是CreateInstance,顾名思议就是创建组件实例,一般情况下我们不会直接调用它,API函数都为我们封装好它了,只有某些特殊情况下才会由我们自己来调用它,这也是VC编写COM组件的好处,使我们有了更多的控制机会,而VB给我们这样的机会则是太少太少了。 IDispatch IDispatch : public IUnknown...

3. 从启动命令行中解析出CLSID,调用ISurrogate::LoadDllServer,创建一个IClassFactory。当某一个来自客户端的CoCreateInstance、CoGetClassObject到来时,IClassFactory::CreateInstance被调用。 PS: 代理exe的命令行为exe路径 {GUID} -Embedding,因此很容易从中解析出CLSID。
