Can't Delete First Record...[RESOLVED - enough]

[milkmood]

What am I missing? When I try to delete the first record (and only the first record) in my PostgreSQL DB, I get an error that says:

An unhandled exception of type 'System.Data.DeletedRowInaccessibleException' occurred in system.data.dll

Additional information: Deleted row information cannot be accessed through the row.

'Public declarations
 
    Dim con As New Odbc.OdbcConnection
    Dim ds As New DataSet
    Dim da As Odbc.OdbcDataAdapter
    Dim sql As String
    Dim inc As Integer
    Dim maxrows As Integer
 
 
'Form Load
 
    Private Sub PartsManager_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
            con.ConnectionString = [LONG ODBC CONNECTION STRING IS HERE]
 
            con.Open()
            sql = "SELECT * FROM customer ORDER BY customername ASC;"
 
            da = New Odbc.OdbcDataAdapter(sql, con)
 
            da.Fill(ds, "customer")
 
            maxrows = ds.Tables("Customer").Rows.Count
 
            inc = 0
 
            NavigateRecords()  'References another sub that tells where to put what, basically
 
    End Sub
 
 
'The Delete button code
 
    Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
        Dim cb As New Odbc.OdbcCommandBuilder(da)
        ds.Tables("customer").Rows(inc).Delete()
        maxrows = maxrows - 1
        inc = 0
        NavigateRecords()
        da.Update(ds, "customer")
    End Sub

Thanks in advance...Let me know if there's something else you need.
