What event should I use to check values entered into a new record on a
form?  The easiest one for me is "On Click" for a particular textbox,
but it requires user input. For the form itself, from "AfterUpdate",
On Current and "Before Update" are candidate--which one?  Or are there
others?

Current fires the instant the user navigates to the record in question, before
they've made any changes. BeforeUpdate fires when the user has completed work
on a record and attempts to save it - e.g. closing the form, moving off the
record, moving to a subform, moving from a subform back to a mainform,
explicitly saving the record with Ctrl-Enter, etc. etc.  It has a Cancel
parameter so if you're doing validation, it's the one to use.

AfterUpdate (as the name implies) fires after the record has successfully been
written to disk.

Also I plan to use this structure: (StockSymbol is a field in the
table bound to the form)

Is there a control on the form with StockSymbol as its control source - a
combo box perhaps? If so, it would be best to reference the control rather
than the fieldname.

Yes, I discovered this myself about combo boxes. What I ended up
doing is putting the warming on BeforeUpdate.


(BT--you're fired.  And you won't get a favorable recommendation from
me for your next job).

<eeep!> Who's BT and what did he do!?


Nothing, he just is a flamer that sometimes posts on this board. I
fired him from replying to me!
