XL97: Error When You Change List Property of Combo Box

MORE INFORMATION

When you add a control to a UserForm in Microsoft Excel 97, you can assign a subroutine to each event to which the control responds: for example, Click, Change, DblClick, and so on. To do this, follow these steps:

1. In the UserForm, double-click the control.
2. In the Procedure list box, select the event to which you want to assign a subroutine.

The code window will display a subroutine for the specified event and control. For example:

   Private Sub ComboBox1_DropButtonClick()
       '<code goes here>
   End Sub
				

The DropButtonClick event for a combo box is triggered whenever the list for the combo box appears or disappears. If the subroutine assigned to this event uses the List property to reset the list for the combo box, you will receive an error message when you run the UserForm and click the combo box. For example:

   Private Sub ComboBox1_DropButtonClick()
       Dim ListArray(0 To 3) As String
       ListArray(0) = Now
       ListArray(1) = Now + 0.25
       ListArray(2) = Now + 0.5
       ListArray(3) = Now + 1
       ComboBox1.List = ListArray
   End Sub
				

It is recommended that you do not use this method to reset the list for a combo box in Microsoft Excel 97. Instead, reset the list when you display the UserForm, or when you click another control in the UserForm, such as a command button.
