Window Handle: 263106

Window ID Number: 0
Parent Window Handle: 590418
Parent Window Text: MonitorForm

I don't think I understand your question. Do you want delphi to find the information the spy program found, or do you want it to retrieve text from that window?

You can use FindWindow(ClassName,WindowName) to get the window handle (either value can be nil, but if you make the WindowName nil, you may not get the window you want). Once you have the handle, you can probably get any information windows has, but I don't know how to read text out of another window.

As bbegley said you can use FindWindow/FindWindowEx to find a window with a certain name. Or you can use EnumWindows function that enumerates all top level windows on the screen. Those functions will return you a window's handle hWnd using which you can get it's text, styles, extended styles, parent and lots of other stuff. As for window's text: once you have a handle of a window you can do something like this:

var 
  TxtLength : Integer;
  AText : pChar
begin 
  TxtLength := GetWindowTextLength(hWnd);
  GetWindowText(hWnd, AText, TxtLength);
  ...
end;
