[AccessD] An Interesting question

The default values are NULL.  What he wants is for something to show in that
field if the value is null.  For example on the Time Sheet there's a text
box bound to a field named Action.  When the value of the current record is
null (new record or not) he wants the box to show "Action".  But he doesn't
want "Action" to be the value of the field in the record. Just wants to show
what amounts to a label on an unlabeled field so that the user has some idea
of what goes into that field.  And yes, the field already has a tool tip.

Well on a new record, it would just be setting the default value.  But if a
field is null, isn't that a value in and of itself?  

See if you can follow my logic on this.  A default value sets a value in a
record automatically, if it is not changed.  If it is changed, then the
record isn't null, it's whatever the user selects (even if it's blank,
that's not null, that's an empty string).  So the null values would only be
for 'older' records, where the value wasn't selected (and there was no
default value).  Therefore, the solution would be to simply set a default
value (I would recommend it being set in the table definition for that
field), and then simply write some code, that would check for nulls in the
current recordset (OnCurrent event), that would set any null field to the
default value defined in the table def.  This would effectively eliminate
any null values in the underlying data, as they are viewed in your form.

A client writes in to ask:

"Can combo boxes and text boxes be configured to display a pre-selected text
if the field is null or the record is new.  For example, could the fields on
the TimeSheet that have no labels have the "labels" show on the combo box or
text box until a user enters something for that field? "

These are bound combos and text boxes.  I can think of a couple kludgey ways
to do this - overlays with label text that are visible only if there's
nothing in the field would be one.  But is there a really good way?
