Edward,

Thanks for your input. I now have the code in the keypress method as follows:

LPARAMETERS nKeyCode, nShiftAltCtrl

LOCAL nkeycode1, nkeycode2
nKeycode1=asc('"')
nKeycode2=asc("'")

if nKeycode=nkeycode1
wait window "Cannot use the quotation mark character in this field !" nowait
nodefault
endif

if nKeycode=nkeycode2
wait window "Cannot use the apostrophe character in this field !" nowait
nodefault
endif

I much prefer this approach compared to having the code in the valid method.

Thanks again, AL
