Hello, i'm new here..i'm a student and i have some problems with my GIS Project. I'm using Visual Studio 2008 SP1 combined with ArcGIS Explorer. The problem i has with this project is, i don't know how to connect the database on my KML file, that is a map file with the database contains details for the KML File..The link below is the sample that i have to refer to but the sample uses web service that is ws.geonames.org.

An ArcGIS forum might be a better place for this. You could also show the code your using so we can evaluate that for poss problems. Try/Catch blocks are great for gathering error information. Debugging also helps so you can check variables and see what line the error occurs. Thanks for helping us help you. Welcome to the forum!

Thx for your reply sir..actually, the GIS Forum seems to be "quiet" since last year..i dont know why..i've post this topic there but no one replies for 3 weeks since i post that..

Actually, its not an error that i was talk about..i just want to know,how to exchange this _webCilent thing to import file from my computer..there is a file that i've compiled named Mineral.KML and its database that contain the data i've key in..the problem is, i don't know how to change this code that can make it's read a file and its database..kinda complicated to explain..its more like GOOGLE MAP but its GIS VERSION using ARCGIS EXPLORER...

To make it understandable, when u search a place that u want, it only shows the place that i've only key in, not from the web base..this is the sample which its grab a service from a website named, ws.geonames.org

Private Sub _webClient_DownloadCompleted(ByVal sender As Object, ByVal e As AsyncCompletedEventArgs)
        ' read the xml file
        '
        Dim doc As XmlDocument = New XmlDocument()
        doc.Load(_resultFile)

        For Each xmlNode As XmlNode In doc.SelectNodes("/geonames/geoname")
            Dim lat As Double = Double.Parse(xmlNode.SelectSingleNode("lat").InnerText)
            Dim lon As Double = Double.Parse(xmlNode.SelectSingleNode("lng").InnerText)
            Dim elev As Double = Double.NaN

            Double.TryParse(xmlNode.SelectSingleNode("elevation").InnerText, elev)

            Dim graphic As Graphic = CreateGraphic(xmlNode.SelectSingleNode("name").InnerText, xmlNode.SelectSingleNode("adminName1").InnerText, xmlNode.SelectSingleNode("countryName").InnerText, lat, lon, elev)

            Dim treeNode As New TreeNode(graphic.Label)
            treeNode.Tag = graphic
            treeView1.Nodes.Add(treeNode)
        Next xmlNode

        EnableControls(True)

        ' zoom to the first node in the tree
        '
        If treeView1.Nodes.Count > 0 Then
            ZoomTo(treeView1.Nodes(0))
        End If
    End Sub
