ProcessList stürzt ab nach kurzer zeit 64Bit

[KodeZwerg]

Zitat von EWeiss:

Delphi-Quellcode:

procedure TProcess.GetUserInformation;
type
  PTokenUser = ^TTokenUser;

  TTokenUser = record
    User: TSIDAndAttributes;
  end;
const
  PROCESS_QUERY_LIMITED_INFORMATION = $1000;

var
  vHandle: THandle;
  vToken: THandle;
//  vUserName: array [0 .. 255] of char;
//  vDomainName: array [0 .. 255] of char;
  vUserName, vDomainName: string;
  vUserNameSize: DWORD;
  vDomainNameSize: DWORD;
  vTokenUser: PTokenUser;
  vInfoSize: Cardinal;
  vUse: SID_NAME_USE;
begin
  FUser := '';
  FDomain := '';

  vHandle := OpenProcess(PROCESS_QUERY_INFORMATION, False, FID);
  if vHandle > 0 then
    try
      if OpenProcessToken(vHandle, TOKEN_QUERY, vToken) then
        try
          GetTokenInformation(vToken, TokenUser, nil, 0, vInfoSize);
          vUserNameSize := SizeOf(vUserName);
          vDomainNameSize := SizeOf(vDomainName);
          vUse := SidTypeUser;
          GetMem(vTokenUser, vInfoSize);
          try
            if not GetTokenInformation(vToken, TokenUser, vTokenUser, vInfoSize, vInfoSize) then
              raise ESystemError.Create;


            vUserNameSize := 0;
            vDomainNameSize := 0;
            LookupAccountSid(nil, vTokenUser.User.Sid, nil, vUserNameSize, nil,
              vDomainNameSize, vUse);
            SetLength(vUserName, NamevUserNameSize);
            SetLength(vDomainName, vDomainNameSize);
            LookupAccountSid(nil, vTokenUser.User.Sid, PChar(vUserName), vUserNameSize, PChar(vDomainName),
              vDomainNameSize, vUse);
//            Result := PChar(vDomainName) + '/' + PChar(vUserName);
            FUser := PChar(vUserName);
            FDomain := PChar(vDomainName); // << Hier stürzt die Anwendung ab nur unter 64Bit.


          finally
            FreeMem(vTokenUser);
          end;
        finally
          CloseHandle(vToken);
        end;
    finally
      CloseHandle(vHandle);
    end;
end;

Weis jemand warum ?

gruss

Ich habe mal den LookupAccountSid Teil angepasst, weiter oben stimmt nun etwas nicht wegen veränderung.... grrrr
