MORE INFORMATION

The online Help topic, Implementing the DBList and DBCombo controls, states that the search argument is cleared when the user presses the BACKSPACE key. This does not occur.

Steps to Reproduce Behavior

1. Start 32-bit Visual Basic 4.0. If it is already running, on the File menu, click New Project.

2. Add a Data and a DBList control to the Form1 form.

3. Set the indicated properties of the following controls:

      Control     Default Name   Property           Value
      -------------------------------------------------------------------
   
      Data        Data1          DatabaseName       BIBLIO.MDB
                                 RecordSource       Authors
   
      DBList      DBList1        DataSource         Data1
                                 RowSource          Data1
                                 BoundColumn        Author
                                 DataField          Author
                                 ListField          Author
                                 MatchEntry         1-Extended Matching
   
   

4. On the Run menu, click Start, or press F5. Type a character and note that the first author name matching the character is highlighted. When you press the BACKSPACE key, nothing happens.
