How to disable any input from keyboard or mouse

[CGR707]

Hi,

Can anybody help me on how to disable the keyboard (including the winkey) and mouse in visual foxpro program.

Here's my sitiution. I owned a small Internet Cafe business, and i somehow develop a program that can control the workstation (reboot/shutdown the PC). What i want to happen is that, when workstation (or PC#2) is already timed, a window will popup, informing the user that he/she times is up and the keyboar and mouse will going to DISABLE.

I want to know, what is the command that can disable the keyboard and mouse function. Is it Possible? Hope it is.

Please help me on this one. Thanks a lot.

FoxPro declaration:

DECLARE INTEGER BlockInput IN user32 INTEGER fBlockIt

Parameters:
fBlockIt
Specifies the function's purpose. If this parameter is TRUE, keyboard and mouse input events are blocked. If this parameter is FALSE, keyboard and mouse events are unblocked.

Return value:
If the function succeeds, the return value is nonzero.

To complete rob444 suggestion, the call to the function is:

BlockInput(1)  && This is blocked
BlockInput(0)  && This is unblocked

Please note that API declarations are case sensitive.

Thanks a lot rob444 and mgagnon. It works. but, i still have a little problem, the <ctrl+alt+del> is still functioning. Is there any way that i can disable that function also?. Thanks for your help.

 

[rob444]

There is an API for disabling <ctrl+alt+del> but I have to look for it myself too.
