Aren't you contradicting yourself when you state "check every
time they enter a value"? If I check every time, then it will throw
an error if I change one of the values. Correcting an error might
involve more than one of the controls. That is why the validation is
row-level; it does not make sense at the individual control level.
What I mean by check a value every time is having a form level function
(say called rowcheck ) and for every column that needs checking put in
the lostfocus rowcheck(). In this function you do the checking and mark
a field (say logical field lValid) in your cursor as .T. or .F. At any
time you will then know if the row is valid or not and that will allow
you to decide if they can change row. Not sure what you mean by "Throw
an error" but the row is either valid or it is not and there is no point
doing anything until they have corrected it (which may involve changing
more than one value, so you won't know when they have finished editing
until it passes the validation).
My problem is getting the current values of the controls. Other
than that, my code works. Unfortunately, not having the current
values of the controls makes a mockery of validation and is a
show-stopper.
Not sure what you mean by current values of the controls. The values in
the underlying cursor are what matter to me and the validate function
can check them.
