How to check the Windows 7 version in VC++.

For testing that the Windows OS running is Windows 7, use this code:

bool IsWindows7()
    bool bOsVersionInfoEx=false;
    DWORD dwType=0UL;
    bool bWin7=false;
    ZeroMemory(&osvi, sizeof(SYSTEM_INFO));
    ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
    if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osvi)) )
        return -1;
    return bWin7;
