怎么把“F50B3F13-19C4-11CF-AA9A-02608C9BABA2”放在CoCreateInstance（）的第一个参数里面？

[cococut]

WINOLEAPI CoCreateInstance(REFCLSID rclsid, LPUNKNOWN pUnkOuter,
DWORD dwClsContext, REFIID riid, LPVOID FAR* ppv);

REFCLSID rclsid；
怎么把字符创“F50B3F13-19C4-11CF-AA9A-02608C9BABA2”，
赋给REFCLSID ，
然后调用CoCreateInstance（rclsid,...............);
谢谢！

This function converts a string generated by the StringFromCLSID function back into the original class identifier.

HRESULT CLSIDFromString(
LPOLESTR lpsz,
LPCLSID pclsid
);
Parameters
lpsz
[in] Long pointer to the null-terminated string that represents the class identifier.
pclsid
[out] Pointer to the class identifier on return.


先用CLSIDFromString将字符串转换为CLSID,接下来就可以了。

CLSID clsid;
clsid = {0xF50B3F13,0x19C4,0x11CF,{0xAA,0x9A,0x02,0x60,0x8C,0x9B,0xAB,0xA2}};

直接这样也可以，CLSID就是一个结构嘛
