So, this is literally my first day writing a single line of C# and working with the .NET SDK. The Developer documentation has been really good thus far and I've been able to understand everything pretty well. Unfortunately, when I got towards the end of the third tutorial, I ran into a problem - my corporate proxy. Since this is my first day working with C#, I'm not sure how to build a function to use IWA to authenticate to our internal proxy. Any help or guidance is greatly appreciated. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows; using System.Windows.Controls;

What is a good way to get an extent object for the features returned by a da.SearchCursor with a where_clause applied? Certainly, I could apply a selection to the FeatureLayer and then use the getSelectedExtent method on the Layer object but frankly, I find SelectLayerByAttribute_management to be an expensive transaction. Add to this that I would also need to go back and clear the selection too. I just want to zoom to the extent of the returned features of the SearchCursor. Ideas? with arcpy.da.SearchCursor(FeatureLayer, "SHAPE@", searchQuery) as rows:     rowCount = 0     for row in rows:         rowCount = rowCount + 1     print str(rowCount)     if rowCount == 0:         pythonaddins.MessageBox("No features found which meet criteria.",                                 "ERROR: INVALID SEARCH CRITERIA", 0)         return     elif rowCount == 1:         if row[0].type == "point":             extent = row[0].extent             df.extent = extent             df.scale = 5000             arcpy.RefreshActiveView()             del extent             del rows         else:             print "Geometry is: " + str(row[0].type)             return     elif rowCount > 1:         # so...now I have a bunch of features/rows returned..hmm         # how to go about getting the full extent for these         # returned features without applying a selection ...
