Presumably there's a table called Dependents that houses all the policy
holders' dependents, and contains a column for PolicyHolderID. In that case,
the query that populates the dependents combo box needs to observe the
current policy holder. There are a few ways to do this. My approach is to
keep everything as clean as possible, so I'd use a static function and call
it from the master form's OnCurrent event.

Here is the template I use for creating static functions:

Static Function CurrentX(Optional lngNew As Long) As Long
'Copy this template each time you need a new set/get function 'Then Replace
"X" with the name of your object, i.e.,"Employee" 'Replace all in current
proc and you're done.

    Dim lngCurrent As Long
    If lngNew <> 0 Then lngCurrent = lngNew
    CurrentX = lngCurrent
End Function

So you'd make something like this:

Static Function CurrentPolicyHolder(Optional lngNew As Long) As Long

    Dim lngCurrent As Long
    If lngNew <> 0 Then lngCurrent = lngNew
    CurrentPolicyHolder = lngCurrent
End Function

In the master form's OnCurrent event, just write this:

    CurrentPolicyHolder(Me.PolicyHolderID)	'adjust the name to suit

Then modify your query to reference the function:

    Select DependentID, DependentName From Dependents Where PolicyHolder =
CurrentPolicyHolder()

That should work as you want.

Hth,
Arthur

Does the table your dependent list is pulled from have some field that links
it to the policy holder?  If it does, then just use a reference to a control
on the main form that holds that connecting information in the query for the
dependent combobox.  If not, then you have a big problem.

Hi Everyone,

I have what I hope is a very simple question.  I have a form with a
subreport (actually two subreports).  This form is used in an insurance
database.  The first main form lists policy holder info, subform 1 lists all
policies that this particular customer has (auto, life, home, etc.) and
subform 2 list all dependents on whatever policy is in subform 1 (e.g.
subform 1 lists auto policy and subform 2 shows that the policy holder's
wife and son are also on this policy.)  Anyway, on subform 2 I have a combo
box where I want to pick the dependent's name (if I'm adding a dependent to
a policy.)  My only problem is, the combo box lists EVERY dependent in my
database.  How do I filter this combo box to only show the policy holder's
dependents?

Any help would be GREATLY appreciated!

Thanks,
Jamie
