Focus and before_update

I have a form where the before_update sub is run before changes are updated.
I need to analyze the text property content for a few textboxes on my form in
order to decide whether the data is correct or no -if not correct, me.undo is
called. I get an error because most of the textboxes do not have the focus.
The validation rule property cannot be used since before_update calls
different functions to analyze the data.

Can anybody point me to a workaround? I do not want to shuffle the focus
around in order to access the text property.

Thanks
 
Well, if you're running the Form's Before_Update, you generally shouldn't
need to check Text values of a control... most likely the control has already
been updated and the .Value of the control will be the same as the .Text of
the control.

Have you considered validating the controls individually on the control's
BeforeUpdate rather than the form's? With this approach the control is
likely to already have the focus (and the Text and Value properties are much
more likely to differ...)

As far as not shuffling the focus around, I personally don't see much of a
reason to not do this. I do it in some forms, and generally things happen
fast enough so that the user doesn't even notice. DoCmd.Echo Off and On may
help if that's what you're worried about.

Click to expand...

I have generally not seen any difference between the .Text and .Value
property of a control in the BeforeUpdate event. I could be wrong; do you
have an example of this? (There is definitely a difference while the user is
typing, but not once the typing is finished and the control value is being
saved in BeforeUpdate.)

There is definitely a difference between the control .Value and a bound
field value, since the update has not yet occurred in the BeforeUpdate
event.
