I am facing some problem in updating ms access with parameters.
I succeeded to insert the data in access with parameters.
My code for inserting the data is:

  Dim dbPath As String = "C:\Users\Abhishek\Documents\ToolDatabase.mdb"  
            Dim connStr As String ="Provider=Microsoft.Jet.OLEDB.4.0;" _
        & "Data Source=" & dbPath & ";Jet OLEDB:Database Password=agupt80;"
         Using connection As New OleDb.OleDbConnection(connStr)
            Dim cmd As New OleDb.OleDbCommand
            Dim trans As OleDb.OleDbTransaction

            If (connection.State = ConnectionState.Closed) Then
                connection.Open() 'Open connection to database
            End If
            cmd.Connection = connection
            trans = connection.BeginTransaction(IsolationLevel.ReadCommitted)
            cmd.Transaction = trans
            cmd.CommandText = "insert into Table1 (Topic, Client, Carrier)  values(@Topic, @Client, @Carrier)"
            With cmd
                    .Parameters.AddWithValue("@Topic", Me.TextBox1.Text)
                    .Parameters.AddWithValue("@Client", Me.TextBox2.Text)
                    .Parameters.AddWithValue("@Carrier", Me.TextBox3.Text)
                    .ExecuteNonQuery() 'Execute command
                End With
                trans.Commit() 'Save record
                MessageBox.Show("Record Saved", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information)
                End Using

And my code for updating the Access is:

 strsql = "UPDATE Table1 SET Topic ='" & TextBox1.Text & "'," _
                            & "Client ='" & TextBox2.Text & "'," _
                             & "Carrier = '" & TextBox3.Text & "'"
                             & "where Topic = '" & ComboBox1.Text & "'"
                             Dim acscmdup As New OleDb.OleDbCommand()
                acscmdup.CommandText = strsql
                If (con.State = ConnectionState.Closed) Then
                End If
                acscmdup.Connection = con
                MessageBox.Show("Database Updated", "Updated..", MessageBoxButtons.OK, MessageBoxIcon.Information)
