I have an web application using Javascript API that connects to a Map Service that has several layers, including a few layers from a file geodatabase. These GDBs have polyline features. I need to build logic that will extract the lat/long of the start and end points of each polyline. Anybody know the best way to do this? I'm open to about any ideas except dealing with python. That's not in my wheelhouse. Can I extract the data from ArcMap somehow? Should I write a ArcMap plugin to get at the data and extract it? Can I pull it through the Rest API? Thanks in advance! ...

I am attempting to implement an ExtractData Widget in Javascript API v3.2. I've finally managed to get the widget to display with my layers and options populated. Here's my issue: The Run Analysis button is set as a page submit input control and is simply reloading my map page. No analysis call is taking place. I'm obviously missing something, but I have no idea what that something is. One thing I'm confused about is that on the Working with Analysis Widgets reference page, it has the following paragraph: I'm a little confused by this. I'm not using ArcGIS Online. We have an ArcGIS Server with my map services. We don't have any ArcGIS.com subscriptions. Why would this be required? Does anybody have any experience implementing the ExtractData widget? I can't find anyone in the entire Interwebs that has even used this thing. Thanks in advance! And if anybody has a better or easier way to simply extract a shapefile from the web map, I'm all ears. ... View more

I'm about to change careers over this! I simply want to allow the user of a Web Application using the Javascript API (3.x) to download a shape file of the current extent. Simple, right? No! Here's what I've done so far: I am using the following js code (which I got from a few posts on here): var extractUrl = "http://mydomain/arcgis/rest/services/System/SpatialAnalysisTools/GPServer/ExtractData" var layers = [app.mapView.map.getLayer(app.mapView.map.layerIds[1])]; var extractData = new ExtractData({ featureLayers: layers, map: app.mapView.map, analysisGpServer: extractUrl }, "analysis-tool"); extractData.startup(); extractData.on("job-result", function (result) { var resultLayer = new FeatureLayer(result.value.url || result.value, { outFields: ['*'], infoTemplate: new InfoTemplate() }); app.mapView.map.addLayer(resultLayer); }); On my ArcGIS Server Manager, I have opened up the SpatialAnalysisTools service for anonymous access. When I run the code, I get a login prompt. (when I put the url, with or without the proxy, in a browser there is no login and it works fine) When I attempt to login, I get  I think the reason I'm getting the Unable to access is because it is building the tokens URL with https and my dev server isn't set up for https. I don't know how to get past that. But the main issue is that I don't want a login at all.  Further, What's with the middle call? I'm wondering if that's what is causing the login.  I just have no ideas at this point. I just need some guidance.  Thanks in advance! ... View more

I have posted about this in the past with no luck. I'm getting desperate. Here's what I have: Web Application with map powered by Javascript API version 3.x. I have a ArcGIS Server with a published mxd with a set of defined layers. On the Web Application, the user can perform a data query and the web application will create a graphics layer representing the query results that is added to the map on the browser. I want the user to be able to click and download a spatial file with the current extent of the map with all displayed layers AND the layer representing the dynamically added graphics layer. Simple question: is this even possible? If so, can somebody give me an idea of how. I looked into ExtractData, but ran into many issues with that just trying to extract the shape file from the layers on the server. I didn't even get as far as trying to get the dynamically created layer exported. If I can't figure this out soon, I'm gonna take up brain surgery. I feel like that would be much easier. Thanks in advance! ... View more

I'm attempting to create labels on streets that would show the AADT (Annual Average Daily Traffic) for a street segment. I can easily do this by creating a spatial view that pulls the AADT as the label.  My problem: The year is hardcoded in the label's SQL Query. I would like to pass in the Year value from the browser and have the correct AADT values applied. Is this something that can be done? As a side note, I've attempted creating a new FeatureLayer on the client using the featureset returned for the street affected. This works fine and I can change the labelinfo for the new featurelayer, but my labels aren't showing. I'm thinking this is a limitation to what the ArcGIS API can do. Is this a feasible solution? ... View more

This task is going to be the death me. I know just enough about ESRI and GIS to be dangerous. I feel like my task should be simple, but I just can't figure it out after searching forums and trying different methods for weeks. All I want to do is click a button on the map and export the current viewable extent to the user in the form of a shapefile. I've tried several built-in processes with absolutely no luck. I cross one hurdle only to fall face first into the next one. I'm currently focused on ExtractData but am running into a login prompt because the creation of the ExtractData object is trying to access arcgis/rest/info?f=json on my server and it doesn't have access to that. I'm so frustrated. This may not even be the best way to do what I'm attempting. Can anybody tell me, or point me to sample code (which I'm having no luck finding,) how to export spatial data from a web map? Thanks in advance!!! ... View more

I've recently migrated a WPF application to ArcGIS Mobile 10.2 from 10.0. My GPS code was all working splendidly until the upgrade. I've tried on two different machines, one with 32-bit OS and the other 64-bit. Both get the same error: [ATTACH=CONFIG]30155[/ATTACH] Any help will be appreciated! ... View more

My forehead is hurting from beating my head on the keyboard over this one. Back in 10.0 days, I simply added the ProjectExtension for the SignIn to the .amp file. 10.2 seems to have changed the format of this file and it's not apparent how to edit the amp file any more. Does anybody know how to get the SignIn project extension added to a project that is destined for Windows Mobile 6? Thanks in advance! ... View more

I have a web site that I'm developing in .NET 4 using ArcObjects 10. I was using the development web server for initial testing and everything was working great, including, of course, the code to get the license. I've now moved the site to IIS, and it will no longer get the license. Every call to IsProductCodeAvailable returns esriLicenseNotLicensed. Any ideas? Thanks in advance! ... View more
