Namespace Dashboard_CreateGeoPointMap
    Partial Public Class Form1
        Inherits Form

        Public Sub New()
            InitializeComponent()

            ' Creates a new dashboard and a data source for this dashboard.
            Dim dashboard As New Dashboard()
            Dim dataSource As New DashboardSqlDataSource()
            Dim sqlQuery As New CustomSqlQuery("Cities", "select * from Cities")
            dataSource.ConnectionParameters =
                New Access97ConnectionParameters("..\..\Data\Cities.mdb", "", "")
            dataSource.Queries.Add(sqlQuery)

            ' Creates a Geo Point Map dashboard item and specifies its data source.
            Dim geopointMap As New GeoPointMapDashboardItem()
            geopointMap.DataSource = dataSource
            geopointMap.DataMember = "Cities"

            ' Loads the map of the world.
