delphi - delphi中的记事本问题

Question

您好，我们使用的是 Delphi 5 版本。在delphi中打开记事本时遇到问题。我们希望通过单击按钮打开记事本并将数据传递给它，以便记事本可以显示该数据。我不想保存它。请帮助我解决这个问题。谢谢。

你可以使用类似的东西:

uses
  Clipbrd;

procedure LaunchNotepad(const Text: string);
var
  SInfo: TStartupInfo;
  PInfo: TProcessInformation;
  Notepad: HWND;
  NoteEdit: HWND;
  ThreadInfo: TGUIThreadInfo;
begin
  ZeroMemory(@SInfo, SizeOf(SInfo));
  SInfo.cb := SizeOf(SInfo);
  ZeroMemory(@PInfo, SizeOf(PInfo));
  CreateProcess(nil, PChar('Notepad'), nil, nil, False,
                NORMAL_PRIORITY_CLASS, nil, nil, sInfo, pInfo);
  WaitForInputIdle(pInfo.hProcess, 5000);

  Notepad := FindWindow('Notepad', nil);
  // or be a little more strict about the instance found
//  Notepad := FindWindow('Notepad', 'Untitled - Notepad');

  if Bool(Notepad) then begin
    NoteEdit := FindWindowEx(Notepad, 0, 'Edit', nil);
    if Bool(NoteEdit) then begin
      SendMessage(NoteEdit, WM_SETTEXT, 0, Longint(Text));

      // To force user is to be asked if changes should be saved
      // when closing the instance
      SendMessage(NoteEdit, EM_SETMODIFY, WPARAM(True), 0);
    end;
  end
  else
  begin
    ZeroMemory(@ThreadInfo, SizeOf(ThreadInfo));
    ThreadInfo.cbSize := SizeOf(ThreadInfo);
    if GetGUIThreadInfo(0, ThreadInfo) then begin
      NoteEdit := ThreadInfo.hwndFocus;
      if Bool(NoteEdit) then begin
        Clipboard.AsText := Text;
        SendMessage(NoteEdit, WM_PASTE, 0, 0);
      end;
    end;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  LaunchNotepad('test string');
end;
