How send WM_HOTKEY with PostMessage?

I want to send WM_HOTKEY to be captured by other application using a global desktop HotShortCut.

The expected Keys are CTRL + F10

This is the only way I found to trigger the capture of WM_HOTKEY:

procedure TfmMain.ButtonTalkClick(Sender: TObject);
var
  Article: TArticleBase;
  Msg: TMessage;
begin
  Article:= GetSelectedArticle;
  if Article <> nil then
  begin
    Clipboard.AsText:= Article.SelectedText;
    Msg.LParamLo:= MOD_CONTROL;
    Msg.LParamHi:= VK_CONTROL or VK_F10;
    PostMessage(HWND_BROADCAST, WM_HOTKEY, 0, Msg.LParam);
  end;
end;

if I change any of the values of Msg.LParamLo or Msg.LParamHi, WM_HOTKEY is not triggered by the other app. But using this way, before the message WM_HOTKEY is captured by the Method:

procedure ManageHotKeyMsg(var Msg: TMessage); message WM_HOTKEY;

The "Windows Execute Dialog" is executed (shortcut "Windows Key" + R)

How is the right way to pass Msg.LParamLo and Msg.LParamHi, to make sure Im sending WM_HOTKEY + "CTRL + F10".

• Raymond says You're Doing It Wrong:

  Why don't you just talk to the other app directly using some sort of standard IPC mechanism?

  Cesar Romero : Tnx Paul. I dont have other app sources. Thats why I should send the keys. Ill try use SendInput.

• Done using PostKeyEx32.

  procedure TfmMain.ButtonTalkClick(Sender: TObject);
  var
    Article: TArticleBase;
  begin
    Article:= GetSelectedArticle;
    if Article <> nil then
    begin
      Clipboard.AsText:= Article.SelectedText;
      PostKeyEx32(VK_F10, [ssCtrl], False);
    end;
  end;
  

  Now my Xananews build can speech :D
