There are several examples of send keys solutions out there. However, I cant seem to get or locate the Virtual Key codes for ")" and other special characters.

Presently, I am away from my development box (on vacation) and wanted to know if what I have written below looks like it will work. if not, I would really appreciate someone to provide me an example of passing these special characters without passing focus or taking focus. Just simply send them to anohter application on a button click
==================================================
procedure TForm1.Button1Click(Sender: TObject);
var hwndNotepad : THandle;
begin
hwndWinamp := FindWindow('NOTEPAD',nil);
SendMessage(hwndNotepad, WM_KEYDOWN, VK_OEM_1, 0);
SendMessage(hwndNotepad, WM_KEYUP, VK_OEM_1, 0);
SendMessage(hwndNotepad, WM_KEYDOWN, VK_OEM_MINUS, 0);
SendMessage(hwndNotepad, WM_KEYUP, VK_OEM_MINUS, 0);
SendMessage(hwndNotepad, WM_KEYDOWN, VK_SHIFT, 0);
SendMessage(hwndNotepad, WM_KEYDOWN, VK_0, 0); //Assuming I need a Shift+0 to get the ")"
SendMessage(hwndNotepad, WM_KEYUP, VK_SHIFT, 0);
SendMessage(hwndNotepad, WM_KEYUP, VK_0, 0);
end;
==================================================
 
In this example, I am assuming that I must do a keydown for shift etc and then the key I want in order to virtually type the desired character(s). Is this correct..?

As tobjectpascal said, or (you have to address the editor component inside notepad!):

procedure TForm1.Button1Click(Sender: TObject);
var
hnp:HWND;
begin
 hnp:= FindWindow('notepad',nil);
 if hnp>0 then begin
  hnp:=FindWindowEx(hnp,0,'Edit',nil);
  SendMessage(hnp, WM_CHAR, Ord('H'),0);
  SendMessage(hnp, WM_CHAR, Ord('i'),0);
  SendMessage(hnp, WM_CHAR, Ord('!'),0);
  PostMessage(hnp, WM_KEYDOWN, VK_RETURN,0);
 end;
end;

BTW, you don't need the virtual shift key to output a  ")"
This will do:
SendMessage(hnp, WM_CHAR, Ord(')'),0);
