Hi all,

Is there some way of finding out from within my application what the
operating system is? I need to be able to distinguish between all Windows OS
from 95 to XP.

Thanks
Paul

Use the GetVersionEx() API to determine the OS. If you need specific
features of the OS (e.g. a certain service pack), and are running under
Windows 2000/XP - use the VerifyVersionInfo() to determine whether the
system supports your requirements.

Assuming you use VCL, the following function returns both an
enumerated version id, plus a "verbal" one.

enum TWinVer {WUN,W9x,W95,W952,W98,W982,WMe,NT3,NT4,NT5,WXP,NTx};

AnsiString __fastcall WinVerString(TWinVer *AWinVer)
{
    AnsiString Result = "Windows ";
    TWinVer    WinVer;

  //IsNT = (Win32Platform == VER_PLATFORM_WIN32_NT);

    switch (Win32Platform)
    {
        case VER_PLATFORM_WIN32_WINDOWS:
            if (Win32MajorVersion == 4){
            if (Win32MinorVersion < 10)
            {
                if (Trim(Win32CSDVersion) == "B") // "C" ?
                   {WinVer = W952; Result += "95 OSR2";}
                else
                   {WinVer = W95 ; Result += "95";     }
            }
            else
            if (Win32MinorVersion < 90)
            {
                if (Trim(Win32CSDVersion) == "A")
                   {WinVer = W982; Result += "98 SE";  }
                else
                   {WinVer = W98 ; Result += "98";     }
            }
            else
            {
                    WinVer = WMe ; Result += "Me";
            }}
            else{   WinVer = W9x ; Result += "9x";     }
            break;

        case VER_PLATFORM_WIN32_NT:
            switch (Win32MajorVersion)
            {
                case  3: WinVer = NT3; Result += "NT_3";  break;
                case  4: WinVer = NT4; Result += "NT_4";  break;
                case  5: if (Win32MinorVersion == 0)    {
                         WinVer = NT5; Result += "2000";}
                         else {
                         WinVer = WXP; Result += "XP"  ;} break;
                default: WinVer = NTx; Result += "NT_X";  break;
            }
            break;

        default:         WinVer = WUN; Result += "Old!";
            break;
    }

    if (AWinVer != NULL) *AWinVer = WinVer;

    return Result;
}

Many thanks, this works fine. One other query, why do you use __fastcall ? I
though this was only for VCL.

I use __fastcall anywhere, as long as I stay in BCB. I switch to other
modifiers only when I have to deal with exported dll funcs.

__fastcall is not VCL specific.
