Re: Programm von Dienst starten lassen (Jetzt aber wirklich

Ja, klar. Hatte das ja schon bei meinem letzen Posting geschrieben. Habe eben noch die kleineren Anpassungen, die Du geschrieben hast, eingebaut.

So sieht das ganze in der letzten Version aus:

Delphi-Quellcode:
procedure StartApp(const App, Parameters, CurDir : TJwString);
var
  StartupInfo : TStartupInfoA;
  ProcInfo : TProcessInformation;
  pEnv : Pointer;
 
  pCurDir,
  pCmdLine : TJwPChar;

  ServiceToken, CopiedToken, UserToken : TJwSecurityToken;
begin

    ZeroMemory(@StartupInfo, sizeof(StartupInfo));
    StartupInfo.cb := SizeOf(StartupInfo);
    StartupInfo.lpDesktop := 'winsta0\default';

    pCmdLine := TJwPChar('"'+App+'" ' + Parameters);

    pCurDir := Nil;
    if Length(CurDir) > 0 then
      pCurDir := TJwPChar(CurDir);


    //get the token from the service system session
    ServiceToken := TJwSecurityToken.CreateTokenEffective(MAXIMUM_ALLOWED);
    TJwAutoPointer.Wrap(ServiceToken);

    //copy the token to be able to change the TokenSessionId
    //Info: Win2000: Only 0
    // WinXP: Service=0, 1.User=0, 2.User=1, 3.User=2, ...
    // WinVista: Service=0, 1.User=1, 2.User=2, 3.User=3, ...
    CopiedToken := TJwSecurityToken.CreateDuplicateExistingToken(ServiceToken.TokenHandle, MAXIMUM_ALLOWED);
    TJwAutoPointer.Wrap(CopiedToken);

    
    //get the token of the logged in user
    if is2000 then
      UserToken := TJwSecurityToken.CreateCompatibilityQueryUserToken(MAXIMUM_ALLOWED, 'explorer.exe')
    else //XP, 2003, Vista, 2008
      UserToken := TJwSecurityToken.CreateWTSQueryUserTokenEx(nil, WtsGetActiveConsoleSessionID);
    TJwAutoPointer.Wrap(UserToken);

    //give the copied token the same sessionid as the logged in user
    CopiedToken.TokenSessionId := UserToken.TokenSessionId;
    

    //create the environment block using the logged in user
    JwaWindows.CreateEnvironmentBlock(@pEnv, UserToken.TokenHandle, false);


    try
     if not CreateProcessAsUser(
      CopiedToken.TokenHandle,
      TJwPChar(App), //__in_opt LPCTSTR lpApplicationName,
      pCmdLine, //__inout_opt LPTSTR lpCommandLine,
      nil, //__in_opt LPSECURITY_ATTRIBUTES lpProcessAttributes,
      nil, //__in_opt LPSECURITY_ATTRIBUTES lpThreadAttributes,
      false, //__in BOOL bInheritHandles,
      CREATE_NEW_CONSOLE or CREATE_DEFAULT_ERROR_MODE or CREATE_UNICODE_ENVIRONMENT,
                         //__in DWORD dwCreationFlags,
      pEnv, //__in_opt LPVOID lpEnvironment,
      pCurDir, //__in_opt LPCTSTR lpCurrentDirectory,
      StartupInfo, //__in LPSTARTUPINFO lpStartupInfo,
      ProcInfo //__out LPPROCESS_INFORMATION lpProcessInformation
     ) then
     raiseLastOsError;
    finally
      DestroyEnvironmentBlock(pEnv);
    end;


    CloseHandle(ProcInfo.hProcess);
    CloseHandle(ProcInfo.hThread);

end;
