在线程函数中调用CoInitializeEx编译出错

[Breeze]

编译的时候报了错
error C2039: 'CoInitializeEx' : is not a member of '`global namespace''
error C2065: 'CoInitializeEx' : undeclared identifier

另外，这是在vc6下通不过，vc2003就能通过
可是调用CoInitialize编译就能通过，那位大侠知道的，指点一下

Somewhere before that ill-fated usage, write
#define _WIN32_WINNT 0x0500
#include <ole2.h>

呵呵，找到问题了，细看了一下msdn,发现有一句话：

Note You must include the #define _WIN32_DCOM preprocessor directive at the beginning of your code to be able to use CoInitializeEx

问题解决了

MSDN真是好东东呀。
