Robert, Is there a way to exclude FeartureLayers from the TOC widget?  I've messed around with the order in TOC.as, following your message above to Jim, but have not figured out how to exclude them altogether. Thanks, as always! -Erik ... View more

Thanks, Bjorn -- glad I came across this thread before too much longer... ... View more

Thanks Matthew... your edited solution worked.  The two pieces I needed to change were resetting the index back to 0 for each row and using the while loop instead of the for loop.  As I'm interpreting this, the problem with the for loop would be that it was still trying to advance by two fields even for the last field, when of course there are no fields after the last field (using the for loop even with the index set to 0 for each row still results in a "list index out of range" error.).  Also, for the record, the data access cursor was far faster than the field calculator in my case with 51 pairs of fields & 4000 records.  The data access cursor took 1 second.  The field calculator took 73 seconds... a much bigger difference than I expected and really significant for a web application (this is feeding an asynchronous GP service).  Thanks for the help! -Erik ...

I've done something very similar.  My code was for 10.0, but it still works in 10.1.  I'm not sure if there's a new, better way to do this, but here's the relevant section of my code: mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] arcpy.MakeFeatureLayer_management("myFC", "My Layer Name") addLayer = arcpy.mapping.Layer("My Layer Name") arcpy.mapping.AddLayer(df,addLayer, "TOP") sourceLayer = "C:\Data\MySymbology.lyr" layerSymb = arcpy.mapping.Layer(sourceLayer) updateLayer = arcpy.mapping.ListLayers(mxd, "My Layer Name", df)[0] arcpy.mapping.UpdateLayer(df, updateLayer, layerSymb, "TRUE") arcpy.RefreshTOC() Hope that helps... -Erik ...

I notice the last post on this topic was from January. Has anybody come across a script that can automate the accumulate attributes process? Jon Don't know if you're still looking for this, but I ended up scripting something using the Geometric Network tools (available as a toolbox in 10.1) and an arcpy.da cursor.  It takes a while to run (~30hours to run my stream network of 410,000 segments) but that's actually a little faster than the performance I was getting using ArcHydro's Accumulate Attributes.  Let me know if you're still interested... ...

I've been having problems with the 64bit background geoprocessing if I run the script in ArcMap and have any of the layers involved in the script in the dataframe.  When I remove everything from the MXD, the script will work. ... View more

I am definately interested.  I sent you a message with more details.  Thanks. Frederic, Here's the core of my code.  I took out a lot of non-essential stuff, so it might not all look right (e.g. if you look in the Design view of FB, it won't look right).  But this should make it easier to see what I did to get the GP results & datagrid working.  Also note that I'm using an asynchronous service-- if yours is synchronous, you'll need to amend it accordingly.  Hope this helps. -Erik <?xml version="1.0" encoding="utf-8"?> <viewer:BaseWidget xmlns:fx="http://ns.adobe.com/mxml/2009"        xmlns:s="library://ns.adobe.com/flex/spark"        xmlns:mx="library://ns.adobe.com/flex/mx"        xmlns:esri="http://www.esri.com/2008/ags"        xmlns:viewer="com.esri.viewer.*"        xmlns:supportClasses="com.esri.ags.skins.supportClasses.*"        xmlns:renderers="com.esri.ags.renderers.*"        widgetConfigLoaded="init()"> <fx:Script>   <![CDATA[    import com.esri.ags.FeatureSet;

I'm interested. How can I learn more? Hi Frederic, I have pursued this and developed a custom widget that includes geoprocessing results as graphics linked to a datagrid.  Modifying the Viewer's Geoprocessing widget ended up not making sense for me-- since I was taking the time to learn Flex and develop custom functionality, it made more sense to incorporate other project-specific custom functionality (beyond the datagrid linked to graphic results) into a custom widget.  The Viewer's Geoprocessing widget is also pretty complex since it is designed to handle many kinds of geoprocessing operations, not just a specific one like my custom widget is, so modifying it would require more time spent trying to understand and modify a lot of code that isn't applicable to my project, anyway. If you are interested in getting into the Flex coding, I would be happy to share some of my code (there are also already several posts and examples out there which helped me along the way.  This blog is a good place to start... http://blogs.esri.com/esri/arcgis/2009/02/19/sychronizing-map-and-datagrid-interaction-with-the-arcgis-api-for-flex/ ) If I ever have the time to dig in a bit more, I still think it would be great to have this as part of the stock Geoprocessing widget functionality and would repost the results here if I do go down that road.  I suspect there are others with more Flex skills who will beat me to it, though! -Erik ...
