Hi Bhavin, You'll need another function which will do a case insensitive check on field name and return case sensitive field name which you can use to access the value. Refer below highlighted code changes. function getCaseSensitiveAttributeName(fieldAliases, fieldName){   for (var key in fieldAliases) {   if (key.toUpperCase() === fieldName.toUpperCase()){   return key;   }   }   return ""; } function selectInBuffer(response){   var feature;   var features = response.features;   var inBuffer = [];   //filter out features that are not actually in buffer, since we got all points in the buffer's bounding box   var mySensitiveField = getCaseSensitiveAttributeName(response.fieldAliases, <<Your Field Name>>);   for (var i = 0; i < features.length; i++) {   feature = features;   if(circle.contains(feature.geometry)){   inBuffer.push(feature.attributes[mySensitiveField]);   }   }   var query = new Query();   query.objectIds = inBuffer;   //use a fast objectIds selection query (should not need to go to the server)   featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function(results){   var totalPopulation = sumPopulation(results);   var r = "";   r = "<b>The total Census Block population within the buffer is <i>" + totalPopulation + "</i>.</b>";   dom.byId("messages").innerHTML = r;   }); } ...

Still with RGB alone you can't create transparency, you'll need to alpha as well. ... View more

1. Use summary statistics tool, statistics field will be your Elev_Diff and statistics will be MIN, don't use any case field. This will create a table with one row, containing your minimum Elev_Diff. 2. Then Iterate field value of this table to get your name parameter. ... View more

Hi Tim, Javascript API as such is free and you are free to use it anywhere without having to pay any licence cost to ESRI, as long as you are using it with ESRI products. Be mindful that ArcGIS Services that you consuming in your JavaScript API are running from an adequately licensed ArcGIS Server installation. If you are consuming services published from your developer license in your personal website, most likely you are in violation of license agreement. Since developer license if for prototyping and testing purpose only, and not for commercial use. As domenico suggested, check with your ESRI distributor in writing to play it safe. ... View more

Hi Duncan, Thanks for your reply. What i'm actually looking for is to establish join between two layers using more than one field. Users should be able to specify the field combinations. ... View more

Hi Stephen, 1. One option is to get envelope of the buffer geometry, this will always be a 4 point rectangle. 2. If you are looking for a minimum bounding rectangle then you may want to create a geoprocessing service using minimum bounding geometry tool. Refer below links on how to go about it. Minimum bounding geometry task - ArcGIS Desktop‌ Publishing geoprocessing service - ArcGIS Help 10.1‌ ... View more

plz check the case for StreetLevelscale, i have made  a mistake in case. ... View more

Sorry din't notice that you are trying to add a dynamic map service to your map, in this case you can't use scale level. When using dynamic map service centerAndZoom's second variable will be a zoom factor. Try below code: var StreetLevelScale = 2500;                  require([        "esri/map", "esri/toolbars/draw",        "esri/symbols/SimpleMarkerSymbol",        "esri/layers/ArcGISDynamicMapServiceLayer",        "esri/symbols/SimpleLineSymbol",        "esri/symbols/SimpleFillSymbol",         "esri/symbols/CartographicLineSymbol",         "esri/graphic",         "esri/Color",         "dojo/dom",         "dojo/on",         "dojo/domReady!"        ], function(          Map, Draw,          SimpleMarkerSymbol, ArcGISDynamicMapServiceLayer, SimpleLineSymbol,          SimpleFillSymbol, CartographicLineSymbol,           Graphic,           Color, dom, on        ) {          map = new Map("mapDiv", {                                          zoom: 12          });            // Base map          var basemap = new ArcGISDynamicMapServiceLayer("http://myserver/Basemap/map/");          basemap.setVisibleLayers([0, 1, 2, 3, 4, 5, 6, 7]);          map.addLayer(basemap);                    map.on("load", initToolbar);                    // Zoom in to local area          map.on("click", function(e){              if (map.getScale() > StreetLevelscale){                  map.centerAt(e.mapPoint);   map.setScale(StreetLevelscale);             }          });  ...

Ssuspect your base map has less than 17 cache level. Change streetLvlZoom variable to say 12 or last level ID. ... View more

Hi Filip, If you want to access the scalebar object outside the context of map event, as you mentioned dojo.hitch is the answer for you. I have modified your code, hope this helps you. <!DOCTYPE html>   <html><head>     <title>Create a Map</title>     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">     <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">     <link rel="stylesheet" href="http://js.arcgis.com/3.10/js/dojo/dijit/themes/claro/claro.css">     <link rel="stylesheet" href="http://js.arcgis.com/3.10/js/esri/css/esri.css">     <style> html, body, #mapDiv{ padding: 0;  margin: 0;  height: 100%; } </style>     <script src="http://js.arcgis.com/3.10/"></script>     <script>     this.map = null;   this._scaleBar = null;   require(["esri/map", "esri/dijit/Scalebar", "dojo/on", "dojo/domReady!"], function(Map, Scalebar, on) {    this.map = new Map("mapDiv", { center: [-56.0, 38.0],  zoom: 3,  basemap: "streets"});   dojo.connect(this.map, "onLoad", dojo.hitch(this, function () {   var options = {"map": this.map, "attachTo": "bottom-left", "scalebarUnit": "dual" }   this._scaleBar = new Scalebar (options);    }));   dojo.connect(this.map, "onClick", dojo.hitch(this, function () {   this._scaleBar.hide();   }));   });   </script>   </head>   <body class="claro"><div id="mapDiv"></div> </body>  </html>  ...

Assuming this code is working, Change this line from mapping.ExportToJPEG(mxd, r"C:\Temp\Map_" + str(x) + ".jpg", df, df_export_width=3004, df_export_height=2125, world_file=True) to mapping.ExportToJPEG(mxd, r"C:\Temp\Map_" + str(row.getValue(<<fieldName>>)) + ".jpg", df, df_export_width=3004, df_export_height=2125, world_file=True) where <<fieldName>>, is the name of the field which has polygon data. ...
