VB - How to set unbound Combobox Item for two column variables

Hello All,

I have a form which has several unbound comboboxes.

In the VB code I set the rowsource of the various comboboxes.

I also have a listbox of existing records where on that listbox's DblClickEvent I go to the Record and update the various unbound comboboxes with the info from that record.

However, one of the comboboxes could have multiple values if I use only one of the rowsource's fields to select by.  Is there a way to do it with two?

For Example.
One of my comboboxes is cboSelectCounty.
My Rowsource is set in the VB code. When the listbox is double clicked I have the code

Private Sub lstExistingRecs_DblClick(Cancel As Integer)
Dim b as long
b = Me.lstExistingRecs.Column(1) ' CountyCodeID

me.cboselectcounty = b
end sub

Everything above works fine as does what I want it to....

HOWEVER, for combobox [cboSelectBkNbrSubBkNbr] the rowsource is set as

"SELECT CountyCodeID, RecBkTypeID, RecBkNbrID, RecBkNbrSubID, BkNbrWhole, RefBk FROM qrySys_ValidRecBkTypeRecBkNbrBkNbrSubByCounty "

When I double click the Listbox I want the selection in [cboSelectBkNbrSubBkNbr] to be based on:
RecBkNbrID
AND
RecBkNbrSubID

I know I can do the RowSource "WHERE RecBkNbrID=x AND  RecBkNbrSubID=y"
but then the drop down list will only show that one particular line if the user needs to change it.

Is there a way to get that one field selected and showing in the combobox without limiting the list to just that one when I'm using 2 variable?

You could modify the RowSource for the combo and concatenate those two fields into a single computed field and make that the first field in the combo box (bound column) and hide it.  something like:

SELECT [RecBnNbrID] & "|" & [RecBnNbrSubID] as Key, CountyCodeID,
RecBkTypeID, RecBkNbrID, RecBkNbrSubID, BkNbrWhole, RefBk
FROM qrySys_ValidRecBkTypeRecBkNbrBkNbrSubByCounty

Then, in the double click event, you would concatenate those values in your list, something like:

me.cboSelectBkNprBusBkNbr = Me.lstExistingRecs.Column(0) & "|" & me.lstExistingRecs.column(1)
