I need to get a handle from control in determinated window, and this window don necessarily have a focus.

If I use WindowFromPoint(ControlPoint), they return the handle only if the control has focus.

I need to get the Handle, using coordinates relatives to ParentWindow of control, something like that:

GetHandleFromPosition(ParentHandle, PositionRelativeOnParent)

Ok, this works for me:

procedure TForm1.Button1Click(Sender: TObject);
hMain, hSub :HWND;
Cap: String;
 if hMain<>0 then begin
   hSub:=ChildWindowfromPoint(hMain, Point(200,200));
   if hSub<>0 then begin
      len := SendMessage(hSub, WM_GETTEXTLENGTH, 0, 0)+1;
      SendMessage(hSub, WM_GETTEXT, Len, longint(Cap));
