Brian,
Thanks for taking the time to reply.. Yes, your
suggestion may be a valid solution in VB (I am using C#)
and logically, your code makes sense. I have found in C#
that the escape key seems to bypass many of
the "expected" invocations such as the key down event. In
my case, the form with the text box in it simply returns
if as a person hit the cancel key. However, not before
the "validating" event is invoked! After posting this
morning, I continued working the problem and finally just
left the validating event out and used the "Leave" event
for the text box instead. I did my validating in the
Leave event handler. This causes the expected result of
exiting unconditionally when the user presses the escape
key, but this created a problem if the user clicked on
the cancel button - of course the "Leave" event handler
was called here also. I fixed this problem by checking
(within my "Leave event" handler) to see if the cancel
button had the focus and if it did, simply returned
without validating! Boy, some of the obfuscated things
that one has to do!
Thanks again for the reply.
