Transperancy of the form will run only in Win2K ro later. You can't set transperancy in Win98, NT or ME.
Here how you can set it (stolen from Solution Samples :o)))

*** Form Init Event

#define BADOS_LOC    "This sample only runs on Windows 2000 or higher."
#define FORM_OPAQUE          255 
#define FORM_FULLTRANSPERANT 0
#define FORM_HALFTRANSPERANT 127 && Almost half :o)

IF VAL(OS(3))<5
    MESSAGEBOX(BADOS_LOC)
    RETURN .F.
ENDIF
DECLARE SetWindowLong              In Win32Api AS _Sol_SetWindowLong Integer, Integer, Integer
DECLARE SetLayeredWindowAttributes In Win32Api AS _Sol_SetLayeredWindowAttributes Integer, String, Integer, Integer

_Sol_SetWindowLong(THISFORM.hWnd, -20, 0x00080000)
_Sol_SetLayeredWindowAttributes(THISFORM.hWnd, 0, FORM_OPAQUE, 2)  && Opaque form

*** or
_Sol_SetLayeredWindowAttributes(THISFORM.hWnd, 0, FORM_FULLTRANSPERANT, 2)  && Full Transperant form

*** or
_Sol_SetLayeredWindowAttributes(THISFORM.hWnd, 0, FORM_HALFTRANSPERANT, 2)

If you run the Solution Sample Example you will see how these functions are used in Change Event of Slider control (Olecontrol1).
