اجرای دستورات dos و گرفتن نتیجه آنها با دلفی

It works by running cmd.exe with the command to be run passed in CommandLine with the current directory optionally passed in the Work. The command is run and the output is returned as a string.

function GetDosOutput(CommandLine: string; Work: string = 'C:\'): string; var SA: TSecurityAttributes; SI: TStartupInfo; PI: TProcessInformation; StdOutPipeRead, StdOutPipeWrite: THandle; WasOK: Boolean; Buffer: array[0..255] of AnsiChar; BytesRead: Cardinal; WorkDir: string; Handle: Boolean; begin Result := ''; with SA do begin nLength := SizeOf(SA); bInheritHandle := True; lpSecurityDescriptor := nil; end; CreatePipe(StdOutPipeRead, StdOutPipeWrite, @SA, 0); try with SI do begin FillChar(SI, SizeOf(SI), 0); cb := SizeOf(SI); dwFlags := STARTF_USESHOWWINDOW or STARTF_USESTDHANDLES; wShowWindow := SW_HIDE; hStdInput := GetStdHandle(STD_INPUT_HANDLE); // don't redirect stdin hStdOutput := StdOutPipeWrite; hStdError := StdOutPipeWrite; end; WorkDir := Work; Handle := CreateProcess(nil, PChar('cmd.exe /C ' + CommandLine), nil, nil, True, 0, nil, PChar(WorkDir), SI, PI); CloseHandle(StdOutPipeWrite); if Handle then try repeat WasOK := ReadFile(StdOutPipeRead, Buffer, 255, BytesRead, nil); if BytesRead > 0 then begin Buffer[BytesRead] := #0; Result := Result + Buffer; end; until not WasOK or (BytesRead = 0); WaitForSingleObject(PI.hProcess, INFINITE); finally CloseHandle(PI.hThread); CloseHandle(PI.hProcess); end; finally CloseHandle(StdOutPipeRead); end; end;

To test it, drop a TMemo, a TEdit and a TButton on a form. Set the button's click event handler as follows:

procedure TForm1.Button1Click(Sender: TObject); begin Memo1.Text := GetDosOutput(Edit1.Text); end;
