XL98: Error Appears When You Change List Property of Combo Box (183384)

MORE INFORMATION

When you add a control to a UserForm in Microsoft Excel 98, 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.

This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The code window then displays 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 that is assigned to this event uses the List property to reset the list for the combo box, you 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
				

Microsoft recommends that you do not use this method to reset the list for a combo box in Microsoft Excel 98. Instead, reset the list when you display the UserForm or when you click another control in the UserForm, such as a command button.
