I would need to subtract from that the Title Bar and Menu Bar size (38) and the Status Bar size (23, which I have turned on in my application). I don't use toolbars in this application, so that does not need to be subtracted.

You're better off using the SYSMETRIC() function to handle the various elements. Unfortunately, the height of the status bar has to be taken into account as well. Between the API and Foxtools, however, it becomes simpler.

* Foxtools must be loaded before using this.
* Get the window handle of the main VFP window
lnhwnd = MainhWnd()
* Initialize API call
DELCARE INTEGER GetWindow IN Win32API;
  INTEGER hwnd, INTEGER dFlag
STORE 0 TO lndesktop, lnlast
lldone = .F.
DO WHILE NOT lldone
  * The desktop is the last child window
  lnlast = GetWindow(lnhwnd, 5) && GW_CHILD
  lldone = (lnlast = 0)
  IF NOT lldone
   lndesktop = lnlast
  ENDIF
ENDDO
STORE 0 TO nTop, nLeft, nBottom, nRight
* Call Foxtools to get the co-ordinates.
= _GetWRect(lndesktop, @nTop, @nLeft, @nBottom, @nRight)

Now it becomes a simple matter of subtraction.
