C# ช่วยแนะนำหน่อยครับพอดีติดปัญหาตรง OdbcConnection ครับ

	Sub Page_Load(sender As Object, e As EventArgs)
		   Dim strConnString As String
		   strConnString = "Driver=Microsoft Access Driver (*.mdb);DBQ="&Server.MapPath("database/mydatabase.mdb")&";UID=;PWD=;"
		   objConn = New OdbcConnection(strConnString)
		   objConn.Open()

		   IF Not Page.IsPostBack() Then	
			BindData()
		   End IF
	End Sub

	Sub BindData()	   
	   strSQL = "SELECT * FROM customer"

	   Dim dtReader As OdbcDataReader
	   objCmd = New OdbcCommand(strSQL, objConn)
	   dtReader = objCmd.ExecuteReader()

	   '*** BindData to GridView ***'
	   myGridView.DataSource = dtReader
	   myGridView.DataBind()

	   dtReader.Close()
	   dtReader = Nothing

	End Sub

	Sub Page_UnLoad()
	   objConn.Close()
	   objConn = Nothing
	End Sub
