XL98: Determining Which Items Are Selected in a List Box

• Microsoft Excel 98 Macintosh Edition

SUMMARY

In Microsoft Excel 98 Macintosh Edition, you can determine which items in a multi-selection list box are selected by using the Selected property of the list box. This article contains an example of how this can be done with a Microsoft Visual Basic for Applications procedure.

MORE INFORMATION

In a custom dialog box, a multi-selection list box allows you to choose any number of items from a list. For example, if a list contains Alpha, Bravo, and Charlie, you can select any, none, or all of those items.

To determine which items are selected, you can use the Selected property of the list box. The Selected property of a multi-selection list box is an array of values: each value is either True, if the item is selected, or False, if the item is not selected. For example, if the list contains 1, 2, 3, and 4, and 2 and 3 are selected, the Selected property would be the following array

False, True, True, False

   A8: Hotel




6. On the dialog sheet, add an OK button that is set to dismiss the dialog box.



7. To add a multi selection list box ("List1") that is linked to Sheet1!$A$1:$A$8 on the dialog sheet, following steps:
   1. On the Forms toolbar, click List Box. To create a list box, Drag the dialog frame.
   
   
   
   2. Select the list box.

      '----------------------------------------------------------------------
   
      Sub ShowSelectedItems()
   
         ' Dimension variables.
         Dim CurList As ListBox, Chosen As Integer
         Dim LTemp As Variant, LItem As Variant
         Dim Counter As Integer, MsgBoxText As String
   
         ' Set an object name for the list box to make it
         ' easier to reference.
         Set CurList = _
           DialogSheets("Dialog1").ListBoxes("List1")
   
         ' Initialize the list so that none of the items are
         ' selected.
         CurList.Selected = _
           Array(False, False, False, False, False, False, False, False)
   
         ' Show the dialog box and set variable 'chosen' to
         ' the value returned by the dialog box.
         chosen = DialogSheets("Dialog1").Show
   
         ' If cancel is chosen, exit the procedure.
         If chosen = 0 Then GoTo canceled
   
         ' Set the variable LTemp equal to the array of values
         ' indicating the selection state of the list box items.
         LTemp = CurList.Selected
   
         ' Initialize the Counter variable.
         Counter = 1
   
         ' Iterate through the loop once for each item in the
         ' array (which is the same as iterating once for each
         ' item in the list box).
         For Each LItem In LTemp
   
         ' If the value of the current item is True...
         If LItem = True Then
   
            ' Add text to the MsgBoxText variable indicating
            ' that the item is selected.
            ' CurList.List(Counter) returns the text of the selected item
            ' ("Alpha", "Bravo", and so on).
            MsgBoxText = MsgBoxText & CurList.List(Counter) & _
              " is selected. " & Chr(13)
   
         ' Otherwise...
         Else
   
            ' Add text to the MsgBoxText variable indicating that
            ' the item is not selected.
            ' CurList.List(Counter) returns the text of the unselected item
            ' ("Alpha", "Bravo", and so on).
            MsgBoxText = MsgBoxText & CurList.List(Counter) & _
              " is NOT selected. " & Chr(13)
   
         End If
   
         ' Increment the Counter so we can get the value of the
         ' next selected item.
         Counter = Counter + 1
   
         ' Repeat until all the items in the list have
         ' been checked.
         Next
   
         ' Display a dialog box indicating the selection state
         ' of each item in the list.
         MsgBox MsgBoxText
   
      ' If the Cancel button was chosen, exit procedure.
      canceled:
   
      End Sub
      '---------------------------------------------------------------------- 




10. To run the subroutine, position the insertion point anywhere in the procedure, and either press F5 or click Run Macro on the Run menu.



11. When the dialog box is displayed, select one or more items in the list box, and choose the OK button.
