Updating a access database from a dataset

Question

This application is a windows form I have two datasets. One from a web service that I call and one from a local access database. My problem is that I am not able to update the local database with the information from the web service dataset. And help would be great. here is my code: Dim d As New DataSet() ' dataset from web services 'For local access database Dim oConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=f:\memberarea.mdb" Dim oConn As New OleDb.OleDbConnection(oConnString) Dim oDS As New DataSet() Dim oAdapt As New OleDb.OleDbDataAdapter("Select firstname,lastname from staff", oConn) Sub get_ds_web() Dim o As New djwebminweb.sync() d.Merge(o.getstaff("Select firstname,LastName from staff where acctnum='10001'")) o = Nothing End Sub Sub get_ds_local() oDS.Clear() oAdapt.Fill(oDS, d.Tables(0).TableName) oConn.Close() End Sub Private Sub updatelocalbd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles updatelocalbd.Click Cursor.Current = Cursors.WaitCursor updatelocalbd.Enabled = False ' disable button once clicked Call update_ds_local() ' update local database Call get_ds_local() ' get new local dataset from db ' Fill New local db combobox ComboBox3.DataSource = oDS.Tables("staff") ComboBox3.DisplayMember = "firstname" ' Fill Merged dataset combobox ComboBox4.DataSource = d.Tables("staff") ComboBox4.DisplayMember = "firstname" Cursor.Current = Cursors.Default End Sub Sub update_ds_local() ' set the olecommand select command oAdapt.SelectCommand = New OleDb.OleDbCommand("Select firstname,LastName from staff", oConn) ' declare a ole command builder Dim custCB As OleDb.OleDbCommandBuilder = New OleDb.OleDbCommandBuilder(oAdapt) 'Open database oConn.Open() 'merge the two record sets together d.Merge(oDS) 'fill the ole dataadapter oAdapt.Fill(d) 'update the dataset oAdapt.Update(d, "staff") 'Close the db connection oConn.Close() End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Cursor.Current = Cursors.WaitCursor Call get_ds_web() ' get remote dataset Call get_ds_local() ' get local dataset 'Fill local db combbox ComboBox1.DataSource = oDS.Tables("staff") ComboBox1.DisplayMember = "firstname" 'Fill website db combbox ComboBox2.DataSource = d.Tables("staff") ComboBox2.DisplayMember = "firstname" Cursor.Current = Cursors.Default End Sub Thank Mike
