auslesen der windowsversion

[glkgereon]

hi
ich muss in einem programm die version der windowsversion auslesesn können
es gibt da in delphi ja sonne konstante, aber laut der hilfe funzt die nur für 95-2000
ich müsste aber auch xp und so bestimmen können
steht da in den registrys nix drin?

Hallo glkbkk,
so kannst du prüfen ob das BS Windows XP ist.

Delphi-Quellcode:

var Version:TOSVersionInfo;
begin
     Version.dwOSVersionInfoSize:=SizeOf(OSVersionInfo);
     GetVersionEx(Version);
     if Version.dwPlatformId=VER_PLATFORM_WIN32_NT
     then if ((Version.dwMajorVersion=5)and(Version.dwMinorVersion>=1))
          then ShowMessage('Windows XP');

Tschüß Markus

hi,

oder du schaust in der Registry unter:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion
bzw. bei NT-Systemen wie XP unter
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion

Es gibt sogar eine API-Funktion dafür. Das wäre der beste Weg.
Steht sogar in der Codelibrary: Version.

Nö
Warum hat sich noch keiner über

Delphi-Quellcode:

          if(osvi.szCSDVersion[0] = 'C') or
            (osvi.szCSDVersion[0] = 'B') then Result := Result + 'OSR2 ';

beschwert?
(der szCSDVersion ist in dem Falle ' A ', ' B ', ... - man achte auf die Leerzeichen )

[edit]
Und eigentlich müsste es bei mir statt

Delphi-Quellcode:

      if (Info.dwMajorVersion = 4) and (Info.dwMinorVersion = 0) then
      begin

eiegntlich

Delphi-Quellcode:

      if (Info.dwMajorVersion = 4) and (Info.dwMinorVersion < 10) then
      begin

heissen, da bei OSR2.1 und OSR2.5 die dwMinorVersion <> 0 ist...

Hallo Nico,
könntest du mal die {$IFDEF}'s erklären, was das soll und warum die erste Funktion:
function GetOSVersionInfo(var Info: TOSVersionInfoEx): Boolean;

[Andreas L.]

Etwas kürzer:
----------------

DLL deklarieren:

Delphi-Quellcode:

{$IFDEF WIN32} 
function GetVersionEx(lpOs : pointer) : BOOL; stdcall; 
external 'kernel32' name 'GetVersionExA'; 
{$ENDIF}

Procedure:

Delphi-Quellcode:

procedure GetWindowsVersion(var Major : integer;
                            var Minor : integer);
var
{$IFDEF WIN32}
  lpOS, lpOS2 : POsVersionInfo;
{$ELSE}
  l : longint;
{$ENDIF}
begin
{$IFDEF WIN32}
   GetMem(lpOS, SizeOf(TOsVersionInfo));
   lpOs^.dwOSVersionInfoSize := SizeOf(TOsVersionInfo);
   while getVersionEx(lpOS) = false do begin
     GetMem(lpos2, lpos^.dwOSVersionInfoSize + 1);
     lpOs2^.dwOSVersionInfoSize:= lpOs^.dwOSVersionInfoSize+1;
     FreeMem(lpOs, lpOs^.dwOSVersionInfoSize);
     lpOS := lpOs2;
   end;
   Major := lpOs^.dwMajorVersion;
   Minor := lpOs^.dwMinorVersion;
   FreeMem(lpOs, lpOs^.dwOSVersionInfoSize);
{$ELSE}
  l := GetVersion;
  Major := LoByte(LoWord(l));
  Minor := HiByte(LoWord(l));
{$ENDIF}
end;

Aufrufen:

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject); 
var 
  Major : integer; 
  Minor : integer; 
begin 
  GetWindowsVersion(Major, Minor); 
  Label1.Caption:=(IntToStr(Major)); 
  Label2.Caption:=(IntToStr(Minor)); 
end;

Sagt mal liegt es daran, dass ich nuicht zu Hause bin oder dass es so früh am Morgen ist? warum kapier ich heute nicht, was ihr da codet? Bei Nico wundert es mich eigentlich nicht aber bei dir, onlinehome, sthehen mir irgendwie die haare zu Berge.

Warum das:

Delphi-Quellcode:

{$IFDEF WIN32}
function GetVersionEx(lpOs : pointer) : BOOL; stdcall;
external 'kernel32' name 'GetVersionExA';
{$ENDIF}

Wenn du es eh nirgens benutzt?

Und das:

Delphi-Quellcode:

   while getVersionEx(lpOS) = false do begin
     GetMem(lpos2, lpos^.dwOSVersionInfoSize + 1);
     lpOs2^.dwOSVersionInfoSize:= lpOs^.dwOSVersionInfoSize+1;
     FreeMem(lpOs, lpOs^.dwOSVersionInfoSize);
     lpOS := lpOs2;
   end;

Sieht für mich einfach nur grausam aus. Du holst dir so lange Speicher bis es klappt? Das kann doch nicht war sein.

Alles in allem mag deine ja kürzer sein, aber erstens bekommst du so nicht die Version im Klartext und irgend was sagt mir, dass da was ganz fürchterliches im Code passiert.
