SAMPLE VISUAL BASIC CODE TO ADD ITEMS TO A LIST

To populate a list box with data from cells on a worksheet


   Sub Example1()
      DialogSheets(1).ListBoxes(1).ListFillRange = "MyWorksheet!A2:A15"
   End Sub

NOTE: "MyWorksheet" is the name of the worksheet that contains the data you would like placed in the list box.

To populate a list box using an array


   Sub Example2()
      DialogSheets(1).ListBoxes(1).List = _
         Array("Mon", "Tue", "Wed", "Thu", "Fri")
   End Sub

To populate the list box with data from a horizontal array of cells

Ordinarily, list boxes are populated with a column of data. If you need to populate a list box with a row of data, use this code:


   Sub Example3()
      DialogSheets(1).ListBoxes(1).List = _
         Worksheets("Sheet1").Range("A1:F1")
   End Sub

NOTE: "Sheet1" is the worksheet that contains your data.

SAMPLE VISUAL BASIC CODE TO REMOVE ITEMS FROM A LIST

To clear all items in a list box with RemoveAllItems


   Sub Example4()
      DialogSheets(1).ListBoxes(1).RemoveAllItems
   End Sub

SAMPLE VISUAL BASIC CODE TO RETRIEVE ITEMS FROM A LIST

To retrieve the selected item in a single-select list box


   Sub Example6()

      Dim LTemp As Variant
      Dim LItem As Variant
      Dim Counter As Integer
      Dim CurList as ListBox

      ' Set an object name for easy referencing of the list box.
      Set CurList = DialogSheets(1).ListBoxes(1)

      ' Put the Selected array into the variable LTemp.
      LTemp = CurList.Selected

      ' Initialize a Counter variable.
      Counter = 1

      ' Iterate through the loop once for each item in the array.
      For Each LItem In LTemp

         ' If the value of the current item is True...
         If LItem = True Then

            ' Show a message box indicating the item is selected.
            MsgBox CurList.List(Counter) & " is selected."

         End If

         ' Increment the Counter to get next selected item.
         Counter = Counter + 1
      Next

   End Sub
