Gene,
you should really only have one READ EVENTS (in your main program and
nowhere else) and one CLEAR EVENTS in your application. You shouldn't
have to use CLEAR EVENTS to close a form.
It sounds like you want your exit button to act like a cancel button.
Set the buttons Cancel property to .T. and then in your validation check
for LASTKEY() <> 27. Again, this is off the top of my head as I haven't
had to deal with the nitty gritty like this in a long time. Note that
pressing the Escape key will now call your exit button's click method.
Frank.

Dear ProFox'ers:
I have LostFocus validation working reasonably well now with a
test form though I am sure that more complications will ensue.
I have just found a weird behaviour of clear events. I thought I
understood clear events.
In my LostFocus, I start by checking if the mouse pointer is on
the Exit button (with sys(1270)) and that the left mouse button is
down (with mdown()). If this is so, I do not want the validation
done, but rather, I want to terminate the form. I use clear events
for this.
My understanding was that execution goes to the statement
immediately after the read events. The VFP 9 docs support this,
stating, "Stops event processing started with READ EVENTS. When CLEAR
EVENTS is executed, program execution continues on the program line
immediately following READ EVENTS."
This is not what happens. The method executing continues to
execute, and when it finishes, then the clear events takes effect (as
best as I can see).
Am I missing something here?
Sincerely,
Gene Wirchenko
