MS Access Checkout Form

I'm working on a database that will track boxes in, out, and back into a warehouse - much like a library.  I need a form that will check the boxes out.  Right now, I have a combo box (cmbBox) that will allow users to select boxes that are currently available ('In' status), a command button (cmdAdd) that will add the selected item from cmbBox to a text box (txtBoxesAwaitingCheckout), another combo box (cmbCheckOutTo) that lists employees to whom the box will be checked out and finally a command button (cmdCheckOut) that actually runs the SQL update statement to check the boxes out ('Out' status).  This works, however since I'm forced to use the BoxID to identify the box in the tblBoxes table for checkout, the user will see this number instead of the BoxNumber field with which they'll be familiar.  I was considering adding the BoxNumber field to the txtBoxesAwaitingCheckout event, but then the SQL statement that I've created will no longer work.  I was also considering using a subform, but I wanted some feedback before I actually went to the trouble of creating one.  Am I on the right track here?

Thanks,

Gary
Private Sub cmdCheckOut_Click()

    Dim strSQL As String

          

    'Update box status in tblBoxes for selected boxes to show "Out"

    strSQL = "UPDATE tblBoxes" & vbCrLf & _

            "SET Status = 'Out'" & vbCrLf & _

            "WHERE BoxID IN (" & Me.txtBoxesAwaitingCheckout & ")"

    

    DoCmd.SetWarnings False

    DoCmd.RunSQL strSQL

    DoCmd.SetWarnings True

    Debug.Print strSQL

    

    Me.txtBoxesAwaitingCheckout.Value = ""

    cmbCheckOutTo.Value = ""

    cmdCheckOut.Enabled = False

    Me.Requery

    Me.Refresh

End Sub
 

Private Sub cmdAdd_Click()

    If IsNull(Me.txtBoxesAwaitingCheckout) Or Me.txtBoxesAwaitingCheckout = "" Then

        Me.txtBoxesAwaitingCheckout = Me.cmbBox

    Else: Me.txtBoxesAwaitingCheckout = Me.txtBoxesAwaitingCheckout & ", " & vbCrLf & Me.cmbBox

    End If

   

    If IsNull(cmbCheckOutTo) Or cmbCheckOutTo = "" _

        Or IsNull(txtBoxesAwaitingCheckout) Or txtBoxesAwaitingCheckout = "" Then

        cmdCheckOut.Enabled = False

    Else: cmdCheckOut.Enabled = True

    End If

End Sub

        End If

    Else:

        cmdAdd.Enabled

    End If

Your Combobox that displays the Boxes should have two Columns:
The BoxID and The BoxName

- Set the RowSource Property of the combobox to a query or SQL statement that will display the BoxID and The BoxName
- Set the Column Count Property of the combobox to: 2
- Set the BoundColumn Property of the combobox to: 1  (This is the BoxID)
Set the Column Widths Property of the combobox to: 0,1
(This will hide the Box ID, and display the BoxName.)

Thanks for your response Jeff.  I do, already have the combo box that lists the 'In' boxes set up as you have listed.  What I'm worried about is with the text box only listing the BoxID, once the user has added multiple boxes to the text box there isn't a good way for them to run back through it to confirm that they have all they right boxes listed before finally performing the check out.

Then, IMHO, you should consider using a Listbox instead of a combobox.

This way you can deep six the whole "add multiple boxes to the text box" code.
And actual SEE the highlited values as you select them in the listbox.
;-)

Here is a sample I just did for another similar question.

Thanks for the attached.  That's a possibility, but w/ our warehouse having over 10,000 boxes, I'm not sure that'll work that well.

I want some sort of subform or text box that will house a running tally of the boxes that the user needs to check out.  The key here would be speed so that they can quickly see, & remove if necessary, all the boxes that are set to be checked out.

Then how about two listboxes.
When you select a value from one, you can "move" in to the other listbox.
Thus one listbox displays a list of all the selected boxes.

Is something like this acceptable?

That's a pretty cool form and would probably work.  I ended up creating a dedicated table to the check out process w/ a subform based on a query for that table.  As the user adds items, the subform fills up & it retrieves pallet, rack & other misc. information.  

How might a couple of queries look for updating (changing status) & inserting (for history) based on the items selected in your form?

"How might a couple of queries look for updating (changing status) & inserting (for history) based on the items selected in your form?"

Well, if you have decided to use your own design to solve this issuse, is this even relevent?

I'm just trying to weigh your solution against mine to see which one would work better, easier.  No big deal - thanks for your time.
