TITLE   :BUG: DBCombo BoundText Incorrect When Setting Text Property
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0,97,97sp1,97sp2,97sp3
OPER/SYS:WINDOWS
KEYWORDS:

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

 - Microsoft Visual Basic Professional and Enterprise Editions for
   Windows, version 5.0
 - Microsoft Visual Studio versions 97, 97sp1, 97sp2, 97sp3
---------------------------------------------------------------------

SYMPTOMS
========

When setting the DBCombo Text property to a new value that exists in the
database, the BoundText property is not updated to hold the contents of the
BoundColumn for the record.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products
listed at the beginning of this article. We are researching this
bug and will post new information here in the Microsoft Knowledge
Base as it becomes available.

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

The DBLIST32.OCX control that ships with Visual Basic 4.0 returned the
BoundText properly in this situation. It is possible that the Visual Basic
5.0 version of DBLIST32.OCX could break an application built with Visual
Basic 4.0 when the DBLIST32.OCX control is upgraded.

Steps to Reproduce Behavior
---------------------------

These steps use the BIBLIO.MDB sample database that ships with Visual
Basic.

1. Start a new Standard EXE Project in Visual Basic. Form1 is created by

   default.

2. Place a data control (Data1) on Form1. Set the DataBaseName property
   to BIBLIO.MDB. Set the RecordsSource to the Authors table.

3. From the Project menu, choose Components. Add the "Microsoft Data Bound
   List Controls" to the project.

4. Add a DBCombo control (DBCombo1) to the form. Set the RowSource property
   to Data1. Set the BoundColumn to AU_ID. Set the ListField to Author.

5. Add a CommandButton (Command1) to Form1. Add the following code to the
   Click event of Command1:

      Private Sub Command1_Click()
         DBCombo1.Text = "Curry, Dave"
         MsgBox DBCombo1.BoundText
      End Sub

6. Save and run the project.

7. Click the CommandButton and note that a blank message box pops up. It
   should have popped up with the AU_ID corresponding to the Author
   "Curry, Dave."
