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

1. Create a Standard EXE in Visual Basic. Form1 is created by default.

2. Place a DataControl, Label, and CommandButton on the form.

3. Set the following Properties of the controls:

        DataConrol(Data1)
        [DatabaseName]   :Biblio.mdb
        [RecordsetType]  :0 - Table
        [RecordSource]   :Authors

        Label(Label1)
        [DataSource]     :Data1
        [DataField]      :Author

4. Add the following code to the CommandButton's Click event:

        Private Sub Command1_Click()

         Data1.Recordset.Index = "PrimaryKey"
         Data1.Recordset.Seek "=", 0     'so that NoMatch=True
         Print Data1.Recordset.NoMatch

        End Sub

5. Press the F5 key to execute code, and note that the "No Current Record" error
  is returned on the Seek method.
