What about using a try-catch construct wherever there is a posibility of
an error being generated?
Then you would know exactly what error appears, even before you try to
close the form, and give the user a chance to correct it.
However, if the grid is a data entry one, you would probably put
validation code in the textboxes of the columns valid event.
In that case I use a textbox property, which I call "lValidate",
initialized in the init event of the textbox, then when the user enters
an invalid code, the validate method can use this property to either let
him go to the next column or stay in the same one until the input is valid.

Dear Vixens and Reynards:
The scenario: you have a form with a grid on it. The user closes
the form. There is a validation error, and in that case, you want the
form to not close.
My solution was to add a property to the form called .griderror.
In the controls that I use in the grid, the validation starts by
setting .griderror to .f. and then does the validation. If there is
an error, it sets .griderror to .t.. The form's .queryunload checks
if .griderror is .t.. If it is, then the form close is cancelled (or
the exit is confirmed, etc.).
This works in my limited testing. I does seem somewhat of a
kludge. Is this a good way to handle it, or is there something better
that I have overlooked?
Sincerely,
Gene Wirchenko
