.NET โค๊ด Combobox ดึงข้อมูลมาจาก MySQL Database ช่วยหน่อยครับ

      Dim sqlGeo As String = "SELECT geo_name FROM geography"
        Dim daGeo As New OleDb.OleDbDataAdapter(sqlGeo, con)
        Dim dtGeo As New DataTable
        daGeo.Fill(dtGeo)
        With cmbGeo
            .DataSource = dtGeo
            .DisplayMember = dtGeo.Columns.Item("geo_name").ColumnName
        End With

	Dim strConnString As String
	strConnString = "Server=localhost;User Id=root; Password=root; Database=mydatabase; Pooling=false"
	objConn = New MySqlConnection(strConnString)
	objConn.Open()

	Dim sqlGeo As String = "SELECT geo_name FROM geography"
	Dim daGeo As New MySqlDataAdapter(sqlGeo, con)
	Dim dtGeo As New DataTable
	daGeo.Fill(dtGeo)
	With cmbGeo
		.DataSource = dtGeo
		.DisplayMember = dtGeo.Columns.Item("geo_name").ColumnName
	End With

	string strConnString = null;
	strConnString = "Server=localhost;User Id=root; Password=root; Database=mydatabase; Pooling=false";
	objConn = new MySqlConnection(strConnString);
	objConn.Open();

	string sqlGeo = "SELECT geo_name FROM geography";
	MySqlDataAdapter daGeo = new MySqlDataAdapter(sqlGeo, con);
	DataTable dtGeo = new DataTable();
	daGeo.Fill(dtGeo);
	cmbGeo.DataSource = dtGeo;
	cmbGeo.DisplayMember = dtGeo.Columns["geo_name"].ColumnName;
