c++调用com组件问题关于CLSIDFromProgID参数问题
现在要调用系统的com组件，只知道这个组件的名字是SB100PC.ocx
查询注册表可得到到那个id为{FE664F43-CCCB-46A4-ADD4-825303E0ADAD}
我要使用这个方法CLSIDFromProgID(OLESTR("SB100PC.？"),&clsid);
参数应该传什么，应该怎么查询啊。

oleview 好像不会告诉你 ProgID

运行OleView.exe
File、View TypeLib...、打开c:\windows\system32\mci32.ocx、File、Save As...
得到的MCI32.IDL：

// Generated .IDL file (by the OLE/COM Object Viewer)
