I am creating my own Token via aspx .net login page. I am setting the Expiration of this Token as well. Once authenticated the user is passed to an aspx page leveraging JavaScript API in a .js page to render the layers and map It is here I am adding the Token to the Map Service: see below var Data = "https://myserver.gov/arcgis/rest/services/Test/blers/MapServer?token="; Data += MapServerToken; map.addLayer(new ArcGISDynamicMapServiceLayer(Data, { opacity: .8 })); If the app stands idle for an extended period of time the Token will expire. Is there a way to test whether a Token is still valid or not via JavaScript? If this is possible I would like to then redirect them back to a login page. Anyone? Thanks in advance

Was able to get the value from the Hidden Input as such var test = document.getElementById('tokentext').value alert('Returned Session variable: ' + test);

I was able to get this working..... ANY Questions PLEASE ASK I have an .aspx with .aspx.vb LOGIN page that grabs the user Credentials and other necessary parameters for creating a Token...the token is created at the login page and stored as a session variable which is then consume in the redirect page. Once at this new page I am using this created TOKEN to render my Secured Services WITHOUT having the login again....

Accessing Session Variables in .JS page I have my Session variable accessible at the .ASPX page.... But I also have a .JS page that is defining the map and layers to render. I need to get the session variable in the .JS page....cant figure out how to... Anyone have any thoughts? I am trying to get the value of the Hidden Input type in .JS page like this IN .JS PAGE var varToken = registry.byId("tokentext"); alert(varToken); In the .aspx page and .aspx.vb page I can alert the Session variable as such IN .NET Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load tokentext.Value = Session("tokentext") End Sub IN .ASPX PAGE <form id="form1" runat="server"> <div> <asp:Label ID="tlabel" runat="server"></asp:Label> <input type="hidden" id="tokentext" name="tokentext" runat="server"/> <asp:Button ID="Button1" runat="server" Text="Button" style="margin-left: 55px" /> </div> <script type="text/javascript"> var tvalue = document.getElementById('<%= tokentext.ClientID%>').value alert(tvalue); </script> </form>

Am I wrong on the String ...maybe something like this Dim referer As String = "https://MyServer.gov/login.aspx" Dim expiration = "10" Dim tokenUrl As String = "https://MyServer.gov/arcgis/tokens?request=gettoken & username=" &username & "&password=" & password & "&referer=" & referer & "&expiration=" & expiration & "& f=json" Anyone ever bypass the User Name authentication via VB.net in a JavaScript app? I have a password for my main Website...then have a bunch of apps inside...I dont want the user to have to enter password 5 million times..

I was able to do this with some older code from the link above....see attached zip. Unzip and create virtual directory on web server Then navigate in URL to http:// server info \ js2shapefile\tests\Test_EsriDrawToShapefile.html Note there is no prj file created....manually project a file to: Projected Coordinate System: WGS_1984_world_Mercator , Meter Then use this .prj file (renamed to output file) and it will render perfectly. I am going to try and get the code to create this .prj file automatically but cant afford the time now. NOTE: that this example is using older code and api references I have not yet tried to update these.

Whats the Default projection when creating a map in JavaScript? WHATS the Code number? I am working on a piece of code that is exporting a shapefile and it should be coming out with the projection of the map...need to do some testing... Is it Web Mercator WGS 84 ? If so whats the number for that?

‎08-13-2014

This is for JavaScript API...but thank you for your thoughts

‎08-13-2014

yea this is going to be a touch one....I looked at that example and only a .shp file is exported....no dbf or shx...and written a while ago.....hmmmmm I tried to bring the files local but not getting the Button to appear to export....have to be doing something wrong... its using https://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.6‌ anyone else out there dable in exporting a Shapefile from graphic?

Is it possible to draw on the map - then Create and Export a shapefile

This html file should work....saw why it would not open for you.... Any other thoughts??? Click button in tool bar zoom out and select a feature and hopefully selecting multiple features ( I want them to highlight as you scroll through the list in the side bar with the next and previous ) Note you have to have multiple features selected for the Next and Previous to appear I am attempting to create a graphic at lines 404 and 516 , although a Highlight would is much more desired... I dont think I can create at line 404 because all the features are present at this poitn if multiple are selected... Thats why I was attempting at lines 516 Just dont know where to go next.... any thoughts would be appreciated.

In my Identify function I am grabbing the result.feature and returning the information on this features including Geometry etc... Then trying to create a graphic and NOTHING. Very confused here......tried it two ways and cannot get a Graphic nor the feature in question to highlight? function executeIdentifyTask (event) { // CALL initializeSidebar action1 = initializeSidebar(app.map); identifyTask = new IdentifyTask(DGIFDataurl); identifyParams = new IdentifyParameters(); identifyParams.tolerance = 10; identifyParams.returnGeometry = true; identifyParams.layerIds = [0]; //identifyParams.layerOption = IdentifyParameters.LAYER_OPTION_ALL; identifyParams.width = app.map.width; identifyParams.height = app.map.height; identifyParams.geometry = event.mapPoint; identifyParams.mapExtent = app.map.extent; var deferred = identifyTask .execute(identifyParams) .addCallback(function (response) { // response is an array of identify result objects // Lets return an array of features. return arrayUtils.map(response, function (result) { var feature = result.feature; var layerName = result.layerName; //----------------------------------------------------------------------------------------------------------- var resultFeatures = result.feature; alert(print_r(resultFeatures)); //call it like this for (var i = 0, il = resultFeatures.length; i < il; i++) { //Get the current feature from the featureSet. //Feature is a graphic var graphic = resultFeatures; // allow different symbols markerSymbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_DIAMOND, 28, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 255, 255]), 2), new dojo.Color([255, 0, 0, 0.85])); lineSymbol = new esri.symbol.CartographicLineSymbol(esri.symbol.CartographicLineSymbol.STYLE_SOLID, new dojo.Color([0, 255, 255]), 10, esri.symbol.CartographicLineSymbol.CAP_ROUND, esri.symbol.CartographicLineSymbol.JOIN_MITER, 5); fillSymbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 2), new dojo.Color([255, 255, 0, 0.85])); // figure out which symbol to use if (graphic.geometry.type === "point" || graphic.geometry.type === "multipoint") { symbol = markerSymbol; } else if (graphic.geometry.type === "line" || graphic.geometry.type === "polyline") { symbol = lineSymbol; } else { symbol = fillSymbol; } graphic.setSymbol(symbol); //Add graphic to the map graphics layer. app.map.graphics.add(graphic); } //----------------------------------------------------------------------------------------------------------- feature.attributes.layerName = layerName; if (layerName === 'DGIF_GIS.DBO.Warblers') { var BirdingTrailSites = new InfoTemplate("", "<table style='width:100%'><tr><td style='width:100%; text-align:center; font-size:14px'>${Species}</td></tr></table>" + "<table style='width:100%'><tr><td style='width:30%'><b>Species</b></td><td style='width:70%'>${Species}</td></tr></table>" ); feature.setInfoTemplate(BirdingTrailSites); } return feature; }); }); app.map.infoWindow.setFeatures([deferred]); app.map.infoWindow.show(event.mapPoint); } // END OF executeIdentifyTask

I am trying to get the attached to work. Open the app Click on the icon in the top header click on a bird in the map the selected attributes are shown to the right. Now zoom out a bit to where the birds are overlapping. Click the birds image again where they are overlapping. Notice now on the right that there are Next and Previous buttons to scroll through the results. Everything works great to this point. BUT I want the feature in the map to either Highlight or replaced with another image. I cannot figure out how to do this. I was in contact with ESRI and their tech could not answer this as well.... As the user scrolls through the multiple return results I want the feature to show up in the map that corresponds with the active result on the right Code is attached in a single HTML file..... I am trying to create a new Graphic with the below...but not working... Can I create a graphic or Highlight the selected graphic???? If so how???? function displayPopupContent(feature){ if(feature){ var content = feature.getContent(); registry.byId("leftPane").set("content", content); var pt = feature.geometry; var sms = new SimpleMarkerSymbol().setStyle( SimpleMarkerSymbol.STYLE_SQUARE).setColor( new Color([255,0,0,0.5])); var graphic1 = new Graphic(pt, sms); app.map.graphics.add(graphic1); } }
