BUG: VBCE: Clicking ComboBox May Trigger Command Click Event

• Microsoft Windows CE Toolkit for Visual Basic 6.0, version 1.0
• Microsoft Windows CE Toolkit for Visual Basic 5.0, version 1.0

SYMPTOMS

When selecting an item from a combo box, the Click event for a command button may fire. This happens on command buttons having shortcut keys and is related to the relative TabIndex values between the command button and the combo box.

RESOLUTION

To prevent the problem remove the shortcut keys from the command buttons. Modifying the TabIndex property of the combo box and ensuring that it does not have the highest TabIndex value on the form works in some cases without removing the shortcut keys.

STATUS

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