Code:

Type TOSVersion=(osUnknown, osUnknown9x, osUnknownNT, osWin95, osWin98, osWin98SE, osWinME, osWinNT, osWin2000, osXP);

function GetOSVersion : TOSVersion;

var osVerInfo : TOSVersionInfo;

majorVer, minorVer : Integer;

begin

result := OsUnknown;

osVerInfo.dwOSVersionInfoSize := SizeOf(TOSVersionInfo);

if GetVersionEx(osVerInfo) then

begin

majorVer := osVerInfo.dwMajorVersion;

minorVer := osVerInfo.dwMinorVersion;

case osVerInfo.dwPlatformId of

VER_PLATFORM_WIN32_NT :

Case majorVer of

4:result := OsWinNT;

5:if minorVer=0 then result := OsWin2000

else

if minorVer=1 then result := OsXP else result := osUnknownNT;

else result := osUnknownNT;

end; {Case majorVer of}

VER_PLATFORM_WIN32_WINDOWS :

case majorVer of

end;{Case minorVer of}

end{case majorVer of}

end;{case osVerInfo.dwPlatformId of}

end;{if GetVersionEx(osVerInfo) then}

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

case GetOSVersion of

osUnknown: Showmessage('Unknown');

osWin95: Showmessage('Win95');

osWinME: Showmessage('WinME');

osWinNT: Showmessage('WinNT');

end;

end;

Code:

procedure TForm1.WinVer;

var WinV: Word;

begin
