FIX: An Empty ListBox Generates a DoubleClick Event

• Microsoft Windows CE Toolkit for Visual Basic 5.0, version 1.0

SYMPTOMS

Double-clicking on an empty ListBox fires the DoubleClick event. The DoubleClick event is not supposed to fire when the ListBox is empty.

RESOLUTION

To work around the issue, add code to the DoubleClick event to detect an empty ListBox, and then exit the procedure as follows:

   Private Sub List1_DblClick()
     If List1.ListCount = 0 Then Exit Sub
     MsgBox "doubleclick" 'this line won't execute when empty.
   End Sub 

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

This problem was corrected in Windows CE Toolkit for Visual Basic 6.0.
