DIM L1 AS LONG
L1 = GetAsyncKeyState(%VK_CONTROL)

L1 will be FALSE if the key hasn't been pressed since the last
call to the function. For other settings, refer to the Win32
Hlp file for the function.

I guess I should start a new thread for this,

I want to be able to set a flag if my program detects the
CTRL key on the keyboard while looping through a section
of my code.

I have read the POffs forum for 3 hrs and the other thread on
Hooking the keybosrd chars, but I dont want CTRL + Something,
i just want the CTRL (or ALT i guess)

Is there a simple way to do this?

Kind Regards
Mike
