cycling through values in a MS Access list box - vba

Question

I have a list box that populates with different sets of data based on user selections.
How can I cycle through any given values that may be in the list box? Is this a For Each statement, or what?

Answer 1

Here is how you iterate through the ListBox:
Dim i as Integer
For i = 0 to Me.ListBoxName.ListCount -1
'Access each item with
'Me.ListBoxName.ItemData(i)
Next i

Answer 2

You can do a For loop to examine each row in the listbox, and do whatever with the rows which are selected. In this example, I display the second column from selected items in the lstLocations listbox. (Column numbering starts with zero.)
Private Sub cmdShowSelections_Click()
Dim lngRow As Long
Dim strMsg As String
With Me.lstLocations
For lngRow = 0 To .ListCount - 1
If .Selected(lngRow) Then
strMsg = strMsg & ", " & .Column(1, lngRow)
End If
Next lngRow
End With
' strip off leading comma and space
If Len(strMsg) > 2 Then
strMsg = Mid(strMsg, 3)
End If
MsgBox strMsg
End Sub
Note I assumed you want the selected items from the list box. If you want all items, selected or not, you could use .ItemData as #DavidRelihan suggested. However, in that case, you could get them from the listbox .RowSource instead.

Answer 3

If working with a listbox in Access I like to capture the listbox recordset and loop through it. Perhaps because I find DAO recordset objects easy to work with.
I'd do something like:
Dim Rst as DAO.Recordset
Set Rst = lbxYourListboxObj.Recordset
'test to assure that there are records
If Rst.EOF then
'some error handling
end if
'I'm just paranoid so I always do this
Rst.MoveFirst
'iterate through list
Do Until Rst.EOF
'do something for each record
'it is nice and convenient to be able to reference the field names directly too!
debug.print Rst!Field1.name,Rst!Field1.value
Rst.MoveNext
Loop
