FIX: DBCombo BoundText Incorrect When Setting Text Property

• 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. This bug has been fixed in Visual Basic 6.0 with the Microsoft Bound Data List Controls 6.0.

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

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."
