HI,

How can I prevent the CTRL+ALT+DEL combination to open the close progam task
list to end a task or shutdown WINDOWS 95/98/2000/XP when I'm running my
application without using a third-party program.

Many thx in advance

Vanni,
Since the OS handles that keystoke combination, I don't believe any FoxPro
code is going to be able to "intercept" it.

Here is a solution for 95 and 98.

* Code from Fabian Belo
FUNCTION Deactivate(b_Estado)

DECLARE INTEGER SystemParametersInfo IN USER32.DLL ;
LONG uAction, ;
LONG uParam, ;
STRING lpvParam, ;
LONG fuWinIni

uAction = 97
lpvParam = '0'
fuWinIni = 0

If b_Estado = .T.
* deshabilita las teclas
uParam = 1
n_Resultado = SystemParametersInfo(@uAction,@uParam,lpvParam,@fuWinIni)
Else
* habilita las teclas
uParam = 0
n_Resultado = SystemParametersInfo(@uAction,@uParam,lpvParam,@fuWinIni)
EndIf
RETURN n_Resultado
ENDFUNC

Thx for the information... but I still seek a solution for the 2000/XP and
NT versions... I alreday knew the solution for the 95/98 systems... but anyway
many thx for those quick responses.

Waiting for the solution for 2000/NT :-)

Greetz.
