รบกวนพี่ช่วยดูทีคับการโชว์ข้อมูลใน texeboxโดยพิมพ์แค่ รหัส คับ

Private Sub getData(ByVal user As String)

        Dim dt As New DataTable()
        Dim connection As New SqlConnection("testConnectionString")

        connection.Open()
        Dim sqlCmd As New SqlCommand("SELECT * from TABLE WHERE Table_Registration = @usersID", connection)
        Dim sqlDa As New SqlDataAdapter(sqlCmd)

        sqlCmd.Parameters.AddWithValue("@usersID", user)
        sqlDa.Fill(dt)
        If dt.Rows.Count > 0 Then
            txt_B_Name.Text = dt.Rows(3)("ColumnName1").ToString()  'Where ColumnName is the Field from the DB that you want to display 
            txt_B_numberTeL.Text = dt.Rows(4)("ColumnName2").ToString()

        End If
        connection.Close()
    End Sub
