ACC97: Keyboard Does Not Respond When TreeView Control Has Focus

• Microsoft Access 97

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

You are unable to type data into a text box or combo box on a tab control that contains a TreeView control on another page. However, you are able to set the value of the text box or combo box with a macro or with Visual Basic for Applications code. This behavior only applies where the TreeView control is on a sub-form and that sub-form is on the Tab control.

NOTE: In addition to the TreeView control, the symptoms discussed within this article have also been reported when using the ListView ActiveX control.

CAUSE

The TreeView control has the focus.

RESOLUTION

If possible, in Design view, place the TreeView control directly onto the Tab control page. When the TreeView control must be on a sub-form, move the focus by clicking a control on the page that contains the TreeView control, or close and reopen the form.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access 97. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
