[AccessD] Deselect all items from a multi-Select list box

Loop through the list items and set the Selected property to 0. I'm in the
middle of putting up a new desk and all of by books and journals are
everywhere but where I need them or I'd offer the actual code. I can't
recall if it's Selected or SelectedItem. So, from Help:

Selected Property
See Also Applies To Example Specifics
You can use the Selected property in Visual Basic to determine if an item in
a list box is selected. Read/write Long.

expression.Selected(lRow)

expression   Required. An expression that returns one of the objects in the
Applies To list.

lRow  Required Long. The item in the list box. The first item is represented
by a zero (0), the second by a one (1), and so on.

Remarks
The Selected property is a zero-based array that contains the selected state
of each item in a list box.

      Setting Description
      True The list box item is selected.
      False   The list box item isn't selected.

You can get or set the Selected property by using Visual Basic.
This property is available only at run time.

When a list box control's MultiSelect property is set to None, only one item
can have its Selected property set to True. When a list box control's
MultiSelect property is set to Simple or Extended, any or all of the items
can have their Selected property set to True. A multiple-selection list box
bound to a field will always have a Value property equal to Null. You use
the Selected property or the ItemsSelected collection to retrieve
information about which items are selected.

You can use the Selected property to select items in a list box by using
Visual Basic. For example, the following expression selects the fifth item
in the list:

Me!Listbox.Selected(4) = True
Example
The following example uses the Selected property to move selected items in
the lstSource list box to the lstDestination list box. The lstDestination
list box's RowSourceType property is set to Value List and the control's
RowSource property is constructed from all the selected items in the
lstSource control. The lstSource list box's MultiSelect property is set to
Extended. The CopySelected( ) procedure is called from the cmdCopyItem
command button.

Private Sub cmdCopyItem_Click()
    CopySelected Me
End Sub

Public Sub CopySelected(ByRef frm As Form)

    Dim ctlSource As Control
    Dim ctlDest As Control
    Dim strItems As String
    Dim intCurrentRow As Integer

    Set ctlSource = frm!lstSource
    Set ctlDest = frm!lstDestination

    For intCurrentRow = 0 To ctlSource.ListCount - 1
        If ctlSource.Selected(intCurrentRow) Then
            strItems = strItems & ctlSource.Column(0, _
                 intCurrentRow) & ";"
        End If
    Next intCurrentRow

    ' Reset destination control's RowSource property.
    ctlDest.RowSource = ""
    ctlDest.RowSource = strItems

    Set ctlSource = Nothing
    Set ctlDest = Nothing

End Sub
