keys as the one of Windows or the whole keyboard.

[Frank Dulk]

Hello

I am developing a software for administration of LAN HOUSE (LAN GAMES) and
it would like to join keys as the one of Windows or the whole keyboard.

Does anybody have some API?

I found this code that works perfectly in Visual Basic.

However in the access it happens mistake with App.hInstance

To Block

hhkLowLevelKybd = SetWindowsHookEx(WH_KEYBOARD_LL, AddressOf
LowLevelKeyboardProc, App.hInstance, 0)


To Unblock

UnhookWindowsHookEx hhkLowLevelKybd
hhkLowLevelKybd = 0

Some clue to work in Access?

You might want to expand on exactly what you are trying to do with the key
press.

All forms in ms-access have a keydown event, and thus you don't need a api
to trap the key stroke.

You probably can get the api code to work, but I not willing to waste my
time looking through that big ugly mess you posted until I know it is worth
the time to do so...

But using the event keydown in the access as would do to block all keyboard.

Ok, I give up!

It's not Spanish.

It's not Portugese.

What is it?
