Summary

This nicely put together C++ header file that will allow you to detect which version of windows your program is currently running on. Currently it supports these versions of Windows:

 

  • Windows 7
  • Windows Vista
  • Windows XP
  • Windows 2000
  • Windows Server

I hope to add more support and more functions at a later date :)

How It Works

Most of the details needed for us to detect the Windows version are in the Windows structure “OSVERSIONINFOEX,” which can be populated with data by calling the “GetVersionEx()” function found in “Windows.h.” However its not as easy as it seams, there is much more work put into detecting the version information, such as:

  • Service Pack Version
  • OS Edition( Ultimate, Pro, etc. )
  • OS Architecture ( x64, x86 )
  • Build Number

How To Use It

Using this code is extremely easy, just include the “os_detection.h” header file into your C++ project and don’t forget to put “#include “os_detection.h”” in your main.cpp file :P

Code: os_detection.h

    if (osvi.dwMajorVersion >= 6)
    {
        if (si.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_AMD64)
        {
            osInfo.OS_Info += ", 64-bit";
            osInfo.OS_Architecture = "64-bit";
        }

        else if (si.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_INTEL)
        {
            osInfo.OS_Info += ", 32-bit";
            osInfo.OS_Architecture = "32-bit";
        }
    }

    return osInfo;
}

#endif

Now, just call the “getWindowsVersionInfo()” function like below:

OSINFO OperatingSystemInfo = getWindowsVersionInfo();

From then on, the version info can be read like such:

string strOSname = OperatingSystemInfo.OS_Name;

For reference, I have put the structure of OSINFO below:

1
2
3
4
5
6
7
8
9
10
11
12
struct OSINFO
{
    string
        OS_Name,
        OS_Edition,
        OS_Service_Pack,
        OS_Architecture,
        OS_Info;

    int
        OS_Build_Number;
};

Uses

So what might one use this source code for? Well, perhaps a feature of your application only works with Windows 7, and you don’t want to have multiple versions of the same application for each Windows version. In that case, you could use the header file to detect the Version of windows and run the specific function that works for that version of windows. You can also use it for:

  • Optimize For Windows Version
  • Better Application Compatibility
  • OS Specific Applications

    Yo brock, can we get the forum back or did GoDaddy get rid of all of it?
