Thank you for sharing all the videos.  Can you share the crime mapping analysis notebook that was demoed in 'ArcGIS Python API for GIS Analysts and Data Scientists' video? Or any sample notebook with Predictive analysis using Machine learning would be helpful. Thanks! ... View more

I am having similar issue but with a custom Addin. I have Silverlight 5 installed. The custom Addin has couple of tools and a behavior. I am able to upload successfully but once I try to run the tool from the viewer it freezes. And when I go back to the edit the viewer from builder it throws the Class load failed error. Any other suggestions? Thanks! ... View more

Jamal, If were not able to fix this issue this is what I figured - I had this same error publishing the map service to AGS 10.1 and a warning was also given after analyzing the map document (which we tend to ignore) - "Layer is being published with custom class extension. " If you experienced similar warning make sure the necessary class extensions applied on the feature classes are installed on your machine. Once I installed these the map document was published successfully. Error I got - The base table definition string  "Conductor" is invalid. Thanks! ... View more

Hi Kim, I too have a table with just village, district, state in India. I can search this in ArcMap manually. I was able to find some addresses like this. But I try to geocode the table this is the error - There was an error trying to process this table. Token required. Do we need any license to the online geocode service? Thanks! ... View more

Thanks Mike! I looked at the posting you referred to but I found ArcGIS Runtime doesn't support workspacefactorytype of SQL Server database. So this might not work as desired. I can think of only looping through the data and editing the a default table everytime the application is connected to a new database. Since its not possible to connect to SQL server in ArcGIS Runtime. Actually I need to attach a mdf file to SQL Server. Is there another way? Thanks! Hi, Are these Access / SQL Server databases actually Geodatabases? Or would you like to join a non-spatial table from the database to a spatial dataset in another datasource? I'm assuming it's the latter... you could take a look at this earlier post which discusses using the JoinDataSource: http://forums.arcgis.com/threads/74686-Joining-Database-with-Map-Layer?

Hi Mike, I wanted this same kind of functionality - to access the attributes of a shapefile added on the fly. For which I contacted Esri Tech support and the GIS Analyst after research concluded that its not possible to access attributes for shapefile. Thanks for the code. Hi, I had a revelation that actually I'd probably confused the issue by keeping the ArcGISDynamicMapServiceLayer in my example whilst introducing a FeatureLayer as well. So I've simplified it to just use a FeatureLayer (below). So it now assumes that you actually want to add the FeatureLayer to the map and display that instead of the ArcGISDynamicMapServiceLayer. I'd recommend you definitely use the accelerated display mode if the feature layer may contain many thousands of graphics, or graphics with complex polygons.
