Allow to select title from comboBox then display for the select title

Hi..

I have one problem...

how to allow the user to select title from comboBox then display acording for the select title to the textbox...

I read that need to create two data Adapters...

I configure one with the SQl statement:

Select TItle, Author, ISBN FROM Books
WHERE Title = ?

But how to configure the other data adapter?

When i run with only one data Adapter, i get the error:

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

The error point to the code below Private Sub frmBooks_load(....
......dbRnR.Fill(DsBooks1) =error

Thanks

this one?

VB Code:

Dim cn As New SqlConnection("integrated security=true;initial catalog=northwind;data source=...")
    Dim da As New SqlDataAdapter("select * from sampletable", cn)
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim dt As New DataTable()
        da.Fill(dt)
        Dim dr As DataRow
        For Each dr In dt.Rows
            ComboBox1.Items.Add(dr(1))
        Next      
End Sub
 
 Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        TextBox1.Text = ComboBox1.SelectedItem
    End Sub

Thanks...

But i used OleDbConnection to connect not SqlConnection..
and i used the data Adapter wizard to edit th SQL code...

is it still the same code to use ?....

This is the code i write into...

Code:

---

Private Sub frmBooks_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
             
        'dbRnR.Fill(DsBooks1)    'error pointed when running
        DisplayRecordPosition()
    End Sub

 
Private Sub cboTitle_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboTitles.SelectedIndexChanged
       
        DsBooks1.Clear()
        dbRnR.SelectCommand.Parameters("Title").Value = cboTitles.Text
        dbRnR.Fill(DsBooks1)
    End Sub
