Hi all, I am using ArcGIS WPF 10.2.2 SDK for my development. I am using ArcGIS WPF API for loading of map, getting map coordinates, loading shapefiles and geotif images, plotting and manipulating polygon on the map. I am now at the phase of deploying the application. I have already gotten my runtime standard license which I have already included into my application. I also built a deployment package "ArcGIS Runtime Deployment Builder 10.2.2" which I temporarily included all the features. I set the ArcGISRuntime.InstallPath to the where I generate the deployment package. However, when I try to load a shapefile or geotif image, it wouldn't load. When I remove the install path, it works. Everything else (plotting and manipulating polygon, getting map coordinate, loading of map) works fine with the deployment install path set. I suspect that when I remove the install path, it uses the sdk libraries. Can anyone tell me how to deploy my application using the generated deployment package? Thanks ... View more

Hi all, I have a map hosted on Geoserver. It is seeding using the Tile Layer. However, when I tried to access the url using ArcGISTiledMapServiceLayer or ArcGISDynamicMapServiceLayer, I get an error the error is "There was an error deserializing the object of type ESRI.ArcGIS.Client.Services.MapServiceInfo. Encountered unexpected character '<'." Any idea how to solve the issue? Thanks. ... View more

Hi all, Does anyone knows if there is a licensing cost when we develop applications using "ArcGIS Runtime SDK for WPF"? If the application is use for academic use, is there a cost? If the application is use for commercial use, is there a cost? If so, does anyone knows how much does it cost? ... View more

Hi all, I have a GraphicsLayer (glShape) on my map where all my shapes is contained and a EditGeometry (egShapes). I need to know how much the shapes has moved, rotate or scaled and then use these value to compute some stuff. 1) I notice before we can get the updated coordinates, we need to trigger egShapes.StopEdit() method. Is there a way to get the updated coordinates without calling StopEdit() method. 2) Besides this, I also notice whenever I deselect a shape (click on a shape that already has StartEdit() triggered), it will trigger the action "GeometryMoved" in egShapes_EditGeometry event even if I didn't move a single inch (just select and deselect). Is there a way to know that it is triggered by deselecting a shape? Thanks in advance. ... View more

Hi all, I need to overlay a small portion of the "World Street Map" with weather information. How can I do it? Details of available files: Number of Files: 2 File format: png (cloud image), pgw (coordinates and other information of the png) Thanks ... View more

Hi, I have encounter NullReferenceException when using EditGeometry and have no idea how to solve it. These are my controls: Map (World_Street_Map) - 1 (call MyMap) Graphics layers - 3 (call it glA, glB) EditGeometry - 1 (call EditGeometry) Handler - 2 (gl_MouseLeftButtonDown, EditGeometry_GeometryEdit, MyMap_MouseLeftButtonDown) Steps: 1) create 2 polygons (call poly1 and poly2) on glA (different location) 2) create a line from middle of each polygon to some location on glB (both polygon links to different location) 3) select poly1 4) select poly2 (without unselecting poly1 first) 5) encounter exception Each handler content: 1) MyMap_MouseLeftButtonDown - EditGeometry.StopEdit() if any polygon is selected. 2) gl_MouseLeftButtonDown - EditGeometry.StopEdit() //clear any selected polygon and update its information (updating is done in EditGeometry_GeometryEdit handler) //Search Associated line in glB and overwrite it with a polyline with transparent color. EditGeometry.StartEdit(e.Graphic); 3) EditGeometry_GeometryEdit - if (e.Action == EditGeometry.Action.EditStarted) {     //get midpoint of selected polygon } else if (e.Action == EditGeometry.Action.EditCompleted) {     //compute moved value x, y     //compute rotated angle     glA.ClearGraphics();     //redraw all polygon in the new position and rotated angle     glB.ClearGraphics();     //redraw all line from mid of poly to the specific location (same location as the initial state) } StackTrace - System.NullReferenceException was unhandled

Hi all, I have a map with arbitrary shape polygon (rectangle, trapezium, etc). When I rotate the polygon, 1) Where is the pivot point? centre of the shape or centre of the boundary of the selected shape. 2) if centre of the boundary of the selected shape, is it possible to set the pivot point to centre of the polygon? ...
