XL98: Determining Which Items Are Selected in a List Box

ID: Q193723

The information in this article applies to:

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

because the first item (1) is not selected, the second and third items (2 and 3) are selected, and the fourth item (4) is not selected.

An example of how to read the Selected array in a Visual Basic procedure is shown below.

To create the procedure, follow these steps:

1. Save and close any current workbooks.

2. Open a new workbook.

3. Hold down the CTRL key, click a sheet tab and choose Insert.

4. Select MS Excel 5.0 Dialog on the General tab and click OK.

5. On the worksheet, enter the following values:

      A1: Alpha
      A2: Bravo
      A3: Charlie
      A4: Delta
      A5: Echo
      A6: Foxtrot
      A7: Golf
      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:

   a. On the Forms toolbar, click List Box. To create a list box, Drag the
       dialog frame.

   b. Select the list box.

   c. In the Name box, type "List1" (without the quotation marks) and
       press ENTER.

   d. From the Format menu, choose Object.

   e. Select the Control tab.

   f. In the Input Range box, type "Sheet1!$A$1:$A$8" (without the
       quotation marks).

   g. Under Selection Type, select the Multi option.

   h. Choose OK to accept the change.

   The list box is now linked to Sheet1!$A$1:$A$8 and is a multi selection
   list box.

8. Press OPTION+F11, then click Module the Insert tab.

9. In the module, enter the following:

   '----------------------------------------------------------------------
   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
   '----------------------------------------------------------------------

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

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

A dialog box is displayed that indicates for each item in the list whether it was selected or not.

Note that you can modify this example and substitute any functions that perform a desired task using the selection state of the list items. For example, you might want to insert the current list item into a cell on a worksheet. To do this, you could use the following command

   Sheets("Sheet1").Cells(10, 10).Value = CurList.List(Counter)

to put the current list item into cell J10 on Sheet1.
