Check key strokes before printing on screen

[csdull33]

I have an Alpha Five program running but two of our machines are having an issue with the numpad where when 7 or 1 is pressed, Home and End are being sent as well as the number. It is due to they type of computer being used. Is there a way to filter the key strokes as they come in, and ignore them when Home or End is found. In a sence, what I'm trying to do is something like:
if (A_USER.KEY.value = "{Home}" ) then
A_USER.KEY.handled = .T.
end if

But alpha five does not accept this for some reason. (It doesn't break anything, just doesn't have the desired affect)
Any thoughts?

I'm not clear where you are trying to use the code. Only forms have onkey events. The snippet you posted is only useful in coding the onkey event.

Might be worth a try on the ones causing you grief.

Yes, this is being used on a form.

I used the above and put a debug in it and it works fine. What do you want it to do when it is handled? It will only keep doing what it was already doing when pressed with your script

I want to block or ignore the key stroke if home or end is pressed. I thought that was what the handled = .t. was for. But I may have been mistaken. I don't wan't home/end to be passed to the application. When I was testing this script, I tried launching a message box when home was pressed to but nothing happend. The onKey didn't seeme to recogize home using this method.

Try this for the onkey event for a form.

IF a_user.key.value = "{Home}" THEN
    a_user.key.handled = .T.
    IF a_user.key.event = "down" THEN
         ui_msg_box("Key","Trapped the home key.")
    END IF
END IF

A simple end should work

IF a_user.key.value = "{Home}" THEN

end
END IF
