过程的输出

你可以使用 Output 来自的属性 TProcess 对象。

尝试此代码

var
  AProcess: TProcess;
begin
  if SaveDialog1.Execute then begin
    AProcess := TProcess.Create(nil);
    try
      AProcess.CommandLine := 'gcc.exe ' + SaveDialog1.FileName + ' -o '
        + TextField23.Text;
      AProcess.Options := AProcess.Options + [poWaitOnExit, poUsePipes];
      AProcess.Execute;

      OutputForm.OutputMemo.Lines.BeginUpdate;
      //OutputForm.OutputMemo.Lines.Clear;
      OutputForm.OutputMemo.Lines.LoadFromStream(AProcess.Output);
      OutputForm.OutputMemo.Lines.EndUpdate;
    finally
      AProcess.Free;
    end;
  end;
end;
