Get Handle to the Notepad and get Text in it as a Result in Pascal Script - Inno Setup

Question

I want to get the Text in the opened Notepad Window to use this text for my next functions. If Notepad is open, (Visible or Hidden), I want to get its Handle using FindWindowand get the text displayed in its working area using WM_GETTEXT.

I need a proper function to do this.

I also read about getting text from Another Window.

UPDATE

Now I obtained Handle like this:

procedure CurPageChanged(CurPageID: Integer);
var
  ResultCode, Notepad: Integer;
begin
   if CurPageID = wpReady then begin
       ShellExec('Open', 'Notepad.exe', '', '', SW_HIDE, ewNoWait, ResultCode);
       Notepad := FindWindowByWindowName('Untitled - Notepad');
       if Notepad <> 0 then begin
         ShellExec('Open', 'TaskKill.exe', '/F /IM Notepad.exe', '', SW_HIDE, ewNoWait, ResultCode);
         Log('Handle to the Notepad has been allocated. HWND is - ' + IntToStr(Notepad));
       end;
   end;
end;

And I need to get its text as String.

Please Guide.

I want to say like `MYTEXTFILENAME.txt - Notepad` according to the text file I am opening in Pascal Script. — GTAVLover, Oct 04 '16 at 06:05
Why do you even use Notepad? That's so unreliable! Why don't you load the file into `TMemo`? — Martin Prikryl, Oct 04 '16 at 06:27
no no I also had an encoding problem like this question shows: http://stackoverflow.com/questions/39844156/inno-setup-pascal-script-loadstringfromfile-not-loading-strings-correctly That's why I loaded it inot Notepad. :-( — GTAVLover, Oct 04 '16 at 06:30
But this function will be useful to anyone who wants to load texts from anothe windows in pascalscript. — GTAVLover, Oct 04 '16 at 06:34
No one really wants to load texts from another window! This is only ever used in hacks. Not in real solutions! — Martin Prikryl, Oct 04 '16 at 06:35
You didn't tell us what is the problem you are trying to workaround. Maybe you should ask a question about your actual problem, and not about your hack. This is typical [XY problem](http://mywiki.wooledge.org/XyProblem). — Martin Prikryl, Oct 04 '16 at 06:35
And this is also a hack.......But it works . http://stackoverflow.com/questions/39064058/get-image-file-information-using-mediainfo-library-in-inno-setup-pascal-script/39091095#39091095 :-( — GTAVLover, Oct 04 '16 at 06:35
This is the problem. I wanted to load text from another window in Inno Setup Pascal Script. — GTAVLover, Oct 04 '16 at 06:36
