BUG: AfterLabelEdit Event Fires After Canceling an Edit

• Microsoft Windows CE Toolkit for Visual Basic 6.0, version 1.0

SYMPTOMS

When using either the Microsoft CE ListView or TreeView control in a Windows CE Toolkit for Visual Basic project, the AfterLabelEdit event fires after canceling a label edit. This behavior is not consistent with Visual Basic. This event should fire only if the label has actually been changed in some fashion.

STATUS

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