Cindy's map opened fine in the ArcGIS.com map viewer so I tried to open it using ArcGIS for Desktop 10.0 SP4. I did not get the error she reported, but all that appeared was the base map (World_Topo_Map) rather than her trails, which presumably are in an uploaded shapefile and not supported until 10.1. - Graeme ...

Many thanks for posting this link Dan I often rue the passing of GENERATE and UNGENERATE from ArcInfo Workstation and planned someday to write replacement Python scripts for them. It's great to see that Jason did this already - I only wish that I had found them sooner. I think Create Features from Text File and Write Features to Text File make great candidates for sharing via ArcGIS Online with tags that include "generate" and "ungenerate" respectively. Or alternatively vote for this ArcGIS Idea to try and have them restored as OOTB functionality. - Graeme ... View more

Thanks for endorsing this issue George I think that ArcPy not being able to modify a grid/graticule interval (and not even being able to delete a grid/graticule) is the biggest impediment I currently have when working with ArcGIS. Thankfully, the second (scale bar alignment) issue you mention seems to have been resolved at 10.1 but for me that was a minor inconvenience compared to the above. - Graeme ... View more

I encountered the same issue (discussed above) today and so developed the Python test script below to demonstrate it. If you run it the expected result is to see the shape area figure printed 3 times but you only see it twice accompanied by the Python error below the code. The error is seen at ArcGIS 10.0 SP4 so I am hoping might be addressed by 10.1. Could someone with 10.1 Pre-release already installed perhaps run the test and see if the problem persists. If in_memory workspaces work like this by design rather than oversight perhaps that can be documented in the 10.1 Online Help (that is now accessible via resources.esri.com). In my application I will be able to workaround it by using CopyFeatures_management to get the feature class back on disk before trying to access its Shape_Area but I'm iterating through 100+ feature classes so would have preferred not to lose that copying time. The in_memory is otherwise working very well to perform 100+ iterations of Intersect between the CopyFeatures to and now as a workaround from in_memory. import arcpy if arcpy.Exists("C:/Temp/Test.gdb"):     arcpy.Delete_management("C:/Temp/Test.gdb") if arcpy.Exists("in_memory"):     arcpy.Delete_management("in_memory") arcpy.CreateFileGDB_management("C:/Temp","test","CURRENT") arcpy.CreateFishnet_management("C:/Temp/test.gdb/fishnetPolys","0 0","0 1","1","1","1","1","#","NO_LABELS","#","POLYGON") fcs = arcpy.SearchCursor("C:/Temp/test.gdb/fishnetPolys") for fc in fcs:     print fc.Shape_Area     print "Above came from Shape_Area field of polygon on disk" del fc,fcs arcpy.CopyFeatures_management("C:/Temp/test.gdb/fishnetPolys","in_memory/fishnetPolysInMemory") arcpy.CopyFeatures_management("in_memory/fishnetPolysInMemory","C:/Temp/test.gdb/fishnetPolysBackOnDisk") fcs = arcpy.SearchCursor("C:/Temp/test.gdb/fishnetPolysBackOnDisk") for fc in fcs:     print fc.Shape_Area      print "Above came from Shape_Area field of polygon copied from disk to in_memory and back to disk" del fc,fcs fcs = arcpy.SearchCursor("in_memory/fishnetPolysInMemory") for fc in fcs:     print fc.Shape_Area     print "Above came from Shape_Area field of polygon copied from disk to in_memory - but you should see error trying to access it" del fc,fcs >>> ================================ RESTART ================================ >>> 1.00024415553 Above came from Shape_Area field of polygon on disk 1.00024415553 Above came from Shape_Area field of polygon copied from disk to in_memory and back to disk Traceback (most recent call last): File "C:/Organisations/Qld DERM/SHAPE_Area_bug.py", line 31, in <module> print fc.Shape_Area File "C:\Program Files\ArcGIS\Desktop10.0\arcpy\arcpy\arcobjects\_base.py", line 25, in __getattr__ x = getattr(self._arc_object, attr) RuntimeError: Row: Field Shape_Area does not exist >>> Note: Background processing is not involved when I see this. ...

Thanks Steve I think your workaround should work without any/many side effects as long as the *.prj file gets re-edited with each major upgrade to a new version.  It's certainly simpler than what I do, so will be usable without having to dive into Python, VB, etc. - Graeme ... View more

This seems long overdue - VBscript and HTML seem very clunky to many non-programmers (i.e. most ArcGIS users).  As a first step why not have the dialog box show just the field names with carriage returns for new lines and any spacing.  Then when part of that gets selected and a Bold button is hit show it in Bold, etc More like ... [NAME] [POSTCODE] Area: [HECTARES] rather than all the HTML tags etc ... View more

Thanks Jeff I'll now do it that "pseudo dynamic text" way.  I'll probably also float this as an ArcGIS Idea to see if it is just me that has been looking for it. ... View more

This idea seems to be related to the one that I would most like to see implemented ...  Reference grids/graticules should be accessible to ArcPy.Mapping ... View more
