[AccessD] VBA Unbound data entry / update form

Not sure where you are stumbling here John.

It's just going to require some code.  

As far as approach on this, do you want to check if the data class is
'dirty', or just compare it to current record when you go to save it?

Susan,

 > John, are you asking how to use disconnected recordsets

No, I am trying to discover how to use unbound forms for 
data entry editing.  It is a similar but not identical thing.

For example if you create a new record in an unbound form, 
there is no recordset to be disconnected.

If you edit an existing record, then yes, kind of.  You 
would (I assume) open a record, grab the field values, old 
values, names and such, and then close the recordset.  That 
assumes a DAO recordset.  You would disconnect the recordset 
(I assume) if you tried to do this in ADO.

 >or are you trying to talk yourself into writing a class 
instead?

No, I am trying to discover the best way to emulate the 
functionality of a bound form.  I do assume that this will 
involve custom written classes, but never having done this I 
am not certain of that.

I have actually thought of taking a bound form, opening it 
to a record (bound forms use DAO recordsets, at least back 
in 2K and previous which this client still uses), then 
grabbing all the field values and "disconnecting" the form 
(and controls).  This would give me a snapshot of the data 
as it existed as the form opened, and a method of 
determining if the data changed.

And no, I do not have a TechRepublic membership.
