Steven, this sample code works perfectly. Can you show your code? What version of ArcGIS API for Flex is used? ... View more

bojan, reading of my current GPS position "Hello Android" book has one small sample of Location Tests: LocationTest/res/layout/main.xml LocationTest/src/org/example/locationtest/LocationTest.java LocationTest/AndroidManifest.xml all sample sources of this book are here adding/storing a new point feature at my location in activity java code (actually to send something to server you need only red part of code): // on your save button click handler function call AsyncTask new AddFeaturesTask().execute();

Steven, is there a nice quick easy way to add a 5px tolerance around the point thats clicked? var q:Query = new Query(); if (yourgeometry is MapPoint) {     var mappoint:MapPoint = yourgeometry as MapPoint;     var newextent:Extent = new Extent(); // not a buffered point, but it works     var delta:Number = 10;     newextent.minx = mappoint.xvalue -delta;     newextent.miny = mappoint.yvalue -delta;     newextent.maxx = mappoint.xvalue +delta;     newextent.maxy = mappoint.yvalue +delta;     q.geometry = newextent; } else {     q.geometry = yourgeometry; } You can also buffer your geometry using GeometryService - http://help.arcgis.com/en/webapi/flex/samples/01nq/01nq00000023000000.htm ...

instructions you gave me does it give me a result that looks like this one ... I tried to show where to find answers to your questions - that's all. Do you want to copy/paste some code? - I'll stand on the sidelines. Do you have plan to develop? You do not like the implementation of the code proposed by other developers. You have some part of own code to show, with better solution - Let's discuss it. Did you see this sample? http://help.arcgis.com/en/webapi/flex/samples/01nq/01nq00000026000000.htm - load/read/parse XML - implemented, show basic information on map - implemented (click to points on map shows InfoWindow). P.S. If you think you have not found an answer to your question, may be you need to write more detailed description of your problem. ... View more

sherlyann23, All "very new" to this starts with reading documentation, look to samples provided by ESRI developers, use this forum search. Try to use GeometryService to project geometries. Take a look to live samples of this service usage. This resource provides the service description associated with a geometry service and is primarily a processing and algorithmic resource that supports operations related to geometries. ... View more

If your "Standart application" built on Flex API from ESRI - the first link in may last thread - it works. If your "Standart application" is Flex Viewer from ESRI - http://help.arcgis.com/en/webapps/flexviewer/help/01m3/01m300000008000000.htm - it works. All other flex applications - the second link in my last thread - it works. P.S. 'Find an address" or "I Want to...." or "Loading.." - where did you got it? If it is your code - so why you can not change it? ... View more

1 From adobe reference result:Function â?? Function that should be called when the request has completed successfully. Must have the following signature:  public function (result:Object, token:Object = null):void; :confused: void - Specifies that a function cannot return any value. // variable=reciever layer // function getLayer(layerId:Number):Layer returns some data with type Layer var layer:Layer = myMap.getLayer(layerId); // no variable=reciever // function can not return any value layer.refresh(); // refresh():void so what variable=reciever gets data, when your function works function onResult(featureSet:FeatureSet, token:Object = null):Number ? 2 function SearchSaleTable works, and never pause or stop working to wait your result or fault function. you need a pencil and a piece of paper (maybe even two pieces of paper) on which you describe everything in detail the entire cycle of receiving and processing data. So the green part of code never wait for red part of code, right? private function SearchSaleTable(tmp:ArrayCollection):Number {     cursor = tmp.createCursor();     var t:String = new String;     while(!cursor.afterLast)     {         t = cursor.current.toString();         var saleQueryTask:QueryTask = new QueryTask();         saleQueryTask.url = "my url";         saleQueryTask.showBusyCursor = true;         saleQueryTask.useAMF = false;         sQuery.where = "SAPROP = '" + t + "'" ;         saleQueryTask.execute(sQuery, new AsyncResponder(onResult, onFault));         function onResult(featureSet:FeatureSet, token:Object = null):void         {             nsum = 0;             for each (var g:Graphic in featureSet.features)             {                 nsum += g.attributes.SAPRICE;             }             trace("on Result " + nsum);             sumSaleValue = sumSaleValue + nsum;         }         function onFault(info:Object, token:Object = null):void         {             Alert.show(info.toString());         }         cursor.moveNext()     }     return sumSaleValue; } Try to remove/comment all places you call trace function. Put in other places: private function SearchSaleTable(tmp:ArrayCollection):Number { trace(">>>start of SearchSaleTable()"); ... ... trace("query send") saleQueryTask.execute(sQuery, new AsyncResponder(onResult, onFault)); ... ... function onResult(featureSet:FeatureSet, token:Object = null):void {     trace("result recieve"); ... ... trace(">>>end of SearchSaleTable()"); return sumSaleValue; my be it helps. ...
