OPER/SYS:WINDOWS winnt
KEYWORDS:vb432 VB4WIN vb5all VS97FixlistSP3 VB5FixListSP3

======================================================================
---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Control Creation, Learning, Professional, and
   Enterprise Editions for Windows, version 5.0
 - Microsoft Visual Basic Standard, Professional, and Enterprise Editions,
   32-bit only, for Windows, version 4.0
 - Microsoft Visual Studio 97
---------------------------------------------------------------------

SYMPTOMS
========

When the Locked property of the 32-bit DBList and DBCombo controls is set
to True, the following problems may occur:

 - Attempts to programmatically modify the Text or BoundText properties
   cause error 387 - Property can't be set on this control.

 - The control does not show data from the current record.

CAUSE
=====

This problem is caused by a bug in the Visual Basic 5.0 Data Bound List
Controls (DBList32.ocx) in the version that ships with the product
(5.00.3714) and in the version that ships with Service Pack 2 (5.01.4319).

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This bug has been corrected in version
5.01.4511 of the DBList32.ocx file that ships in Visual Studio 97 Service
Pack 3.

For a list of the Visual Basic 5.0 bugs that were fixed in the Visual
Studio 97 Service Pack 3, please see the following article in the Microsoft
Knowledge Base:

   ARTICLE-ID: Q175450
   TITLE     : INFO: Visual Basic 5.0 Fixes in Visual Studio 97
               Service Pack 3

MORE INFORMATION
================

This bug does not occur with any 16-bit versions of Visual Basic.

Although this bug did not occur with the 32-bit version of Visual Basic
4.0, the bug can cause problems with 32-bit applications built by Visual
Basic 4.0.

If an application built by the 32-bit version of Visual Basic 4.0 uses the
Data Bound List Controls and an application built by Visual Basic 5.0 is
installed on that same machine, the older version of the Data Bound List
Controls will be overwritten and the bug may occur.
