Hi,

>Also I would like to create custom methods for the _SCREEN.

The VFP help entry for ' _SCREEN Properties,Methods and Events' gives an example for both of the above. Essentially:

_Screen.NewObject("oSH","ScreenHook","myScreen.prg")

*myScreen.prg
DEFINE CLASS ScreenHook as Custom
  oScr = _SCREEN
  PROC oScr.Hide()
    * whatever
  ENDPROC
  PROC oScr.CustomMethod
    * whatever
  ENDPROC
ENDDEFINE

HTH,
Viv
