This example uses the ListIndex property to determine the correct subroutine to run, based on the selection in the combo box on the command bar named “My Custom Bar.” Because the procedure uses ListIndex, the text in the combo box can be anything.
Sub processSelection()
Dim userChoice As Long
userChoice = CommandBars("My Custom Bar").Controls(1).ListIndex
Select Case userChoice
Case 1
chartcourse
Case 2
displaygraph
Case Else
MsgBox ("Invalid choice. Please choose again.")
End Select
End Sub
