Getting the user's OS

I'm trying to detect a user's OS but I'm not getting the correct results. Is there something I'm missing?

Code:

---

OSVERSIONINFO osInfo;

        // Get Windows version.
        ZeroMemory(&osInfo, sizeof(osInfo));
        GetVersionEx(&osInfo);

        if(osInfo.dwPlatformId == 1)
        {
                if((osInfo.dwMajorVersion == 4) && (osInfo.dwMinorVersion == 0))
                        objSystemInfo.OperatingSystem.Windows95 = true;
                else if((osInfo.dwMajorVersion == 4) && (osInfo.dwMinorVersion == 10))
                        objSystemInfo.OperatingSystem.Windows98 = true;
                else if((osInfo.dwMajorVersion == 4) && (osInfo.dwMinorVersion == 90))
                        objSystemInfo.OperatingSystem.WindowsME = true;
        }

        // Win NT
        else if(osInfo.dwPlatformId == 2)
        {
                if((osInfo.dwMajorVersion == 4) && (osInfo.dwMinorVersion == 0))
                        objSystemInfo.OperatingSystem.WindowsNT4 = true;
                else if((osInfo.dwMajorVersion == 5) && (osInfo.dwMinorVersion == 0))
                        objSystemInfo.OperatingSystem.Windows2000 = true;
                else if((osInfo.dwMajorVersion == 5) && (osInfo.dwMinorVersion == 1))
                        objSystemInfo.OperatingSystem.WindowsXP = true;
                else if((osInfo.dwMajorVersion == 5) && (osInfo.dwMinorVersion == 2))
                {
                        if(GetSystemMetrics(89))       
                                objSystemInfo.OperatingSystem.WindowsServer2003R2 = true;
                }
                else if((osInfo.dwMajorVersion == 6) && (osInfo.dwMinorVersion == 0))
                        objSystemInfo.OperatingSystem.WindowsVista = true;
                else if((osInfo.dwMajorVersion == 6) && (osInfo.dwMinorVersion == 1))
                        objSystemInfo.OperatingSystem.Windows7 = true;
        }

For extra info, I'm getting '0' for osInfo.dwPlatformId.

You mean, like doing something sane like RTFM perhaps?

> Before calling the GetVersionEx function, set the dwOSVersionInfoSize member of the structure as appropriate to indicate which data structure is being passed to this function.

Adding you to my be aware / PMS developer list.

And there is no such member for the structure I'm using. Read on and get some pills.

Indeed, RTFM.

Ah, yes... my mistake. But seriously, work on the attitude. Some of us come from a professional background and looking at your post just sounds really amateur and rude.

Professional?
Ha - don't make me laugh - what sort of pro posts on a board without reading the manual first?

Just so you know Salem is probably one of the most knowledgeable and helpful programmers on this board. His attitude or more appropriately the shared attitude of the members of the board comes from answering ten million questions that could have been answered with a simple Google search or a quick read on MSDN. No one in the world has the Win32 API memorized so I guess what we are saying here is have the help docs readily available while programming in Win32. Most companies even give you an MSDN subscription and/or get MSDN on CD's/DVD's every quarter that you can then install on your machine. If there is one thing we have readily available today it is information.
