'cmd-Befehl' in Delphi ausführen mit Ausgabe

[alleinherrscher]

Hi und willkommen im Forum.

Das liegt daran, dass neuere Delphi Versionen die Unicode Version von CreateProcess verwenden. In dieser Version ist der Parameter lpCommandLine veränderlich und nicht konstant. Siehe auch: http://embarcadero.newsgroups.archiv...104294937.html

Daher musst du folgenden Code verwenden:

Delphi-Quellcode:

function GetConsoleOutput(const Command : string;
                          Output, Errors : TStringList) : Boolean;
var
  Buffer            : array[0..255] of Char;
  CreationFlags     : DWORD;
  NumberOfBytesRead : DWORD;
  PipeErrorsRead    : THandle;
  PipeErrorsWrite   : THandle;
  PipeOutputRead    : THandle;
  PipeOutputWrite   : THandle;
  ProcessInfo       : TProcessInformation;
  SecurityAttr      : TSecurityAttributes;
  StartupInfo       : TStartupInfo;
  Stream            : TMemoryStream;
  sCmd              : string;
begin
  //Initialisierung ProcessInfo
  FillChar(ProcessInfo, SizeOf(TProcessInformation), 0);

  //Initialisierung SecurityAttr
  FillChar(SecurityAttr, SizeOf(TSecurityAttributes), 0);
  SecurityAttr.nLength              := SizeOf(TSecurityAttributes);
  SecurityAttr.bInheritHandle       := True;
  SecurityAttr.lpSecurityDescriptor := nil;

  //Pipes erzeugen
  CreatePipe(PipeOutputRead, PipeOutputWrite, @SecurityAttr, 0);
  CreatePipe(PipeErrorsRead, PipeErrorsWrite, @SecurityAttr, 0);

  //Initialisierung StartupInfo
  FillChar(StartupInfo, SizeOf(TStartupInfo), 0);
  StartupInfo.cb          := SizeOf(TStartupInfo);
  StartupInfo.hStdInput   := 0;
  StartupInfo.hStdOutput  := PipeOutputWrite;
  StartupInfo.hStdError   := PipeErrorsWrite;
  StartupInfo.wShowWindow := SW_HIDE;
  StartupInfo.dwFlags     := STARTF_USESHOWWINDOW or STARTF_USESTDHANDLES;

  CreationFlags := CREATE_DEFAULT_ERROR_MODE or
                   CREATE_NEW_CONSOLE or
                   NORMAL_PRIORITY_CLASS;
  sCmd:=Command;
  UniqueString(sCmd);
  if CreateProcess(nil,
                   (PChar(sCmd)),
                   nil,
                   nil,
                   True,
                   CreationFlags,
                   nil,
                   nil,
                   StartupInfo,
                   ProcessInfo) then
  begin
    Result := True;
    //Write-Pipes schließen
    CloseHandle(PipeOutputWrite);
    CloseHandle(PipeErrorsWrite);

    //Ausgabe Read-Pipe auslesen
    Stream := TMemoryStream.Create;
    try
      while ReadFile(PipeOutputRead, Buffer, 255, NumberOfBytesRead, nil) do
      begin
        Stream.Write(Buffer, NumberOfBytesRead);
      end;
      Stream.Position := 0;
      Output.LoadFromStream(Stream);
    finally
      Stream.Free;
    end;
    CloseHandle(PipeOutputRead);

    //Fehler Read-Pipe auslesen
    Stream := TMemoryStream.Create;
    try
      while ReadFile(PipeErrorsRead, Buffer, 255, NumberOfBytesRead, nil) do
      begin
        Stream.Write(Buffer, NumberOfBytesRead);
      end;
      Stream.Position := 0;
      Errors.LoadFromStream(Stream);
    finally
      Stream.Free;
    end;
    CloseHandle(PipeErrorsRead);

    WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
    CloseHandle(ProcessInfo.hProcess);
  end
  else
  begin
    Result := False;
    CloseHandle(PipeOutputRead);
    CloseHandle(PipeOutputWrite);
    CloseHandle(PipeErrorsRead);
    CloseHandle(PipeErrorsWrite);
  end;
end;
