windows版本检测函数

//复制一下内容到文本中，改名文本为WindowsVersion.h，这样就可以在你的程序中调用BOOL DisplaySystemVersion(LPTSTR buffer)函数了，当然包含头文件了；

//下面的函数其实也不是原创了，这里我简单添加了一些定义，这样这个文件就可以在VC6中应用了；

bool isWin7()

BOOL bOsVersionInfoEx;

bOsVersionInfoEx = GetVersionEx((OSVERSIONINFO*) &osvi);

osvi.dwMajorVersion == 6 &&

osvi.dwMinorVersion == 1 )

{

return true;

else
