I have spend a week off and on trying to get VSCode to work as it used to. I found this gem from Copilot. Presumably other people know about this. I don't like the solutions proposed much. ArcGIS Pro’s integration with VSCode is well-intentioned - but a bit heavy-handed. When you launch VSCode from within ArcGIS Pro, it tries to “help” by injecting its environment into your global settings.json , but it sets: the path to the env folder without python.exe on the end —which is a folder, not an executable. VSCode then tries to run that as if it were python.exe, and boom: you get the conda.exe error because it’s misinterpreting the path. ... View more

Date arithmetic is awful. The best thing is to convert all date fields to ISO strings. Then comparisons and ranges are easy and if you need to do date arithmetic you can convert the ISO to a date object easily. ISO format is set up so that dates are in string sort order, the timezone can be appended (UTC = Z) or the offset added. It is easy to get a subset to extract part of the date because they are in fixed widths. Date formats often do not go before 1970 (Microsoft), 1900 (Unix) so don't use them. ... View more

If you just try to edit the dashboard and replace the source all settings will be lost so you have to rebuild the dashboard from scratch. ... View more

In short you can't! Well it is not supported in the interactive interface. There is now an unsupported workaround provided by the Esri consulting team using the AGOL Assistant where you can do a search and replace for the item ID. If you know the Item IDs..... (Just do a search for AGOL Assistant and log in again). Maybe you can find the Item IDs (the new one is easy enough from the new webmap and you may have the old webmap. If you have a new feature layer then create a new web map that references the new featurelayer otherwise you will have to do two updates, one for the webmap and another for the featurelayer. I wrote a short python script to recursively look through the dashboard to find all Item IDs in the dashboard. I am intending to do the update too but haven't finished it yet. # dashboard references 2 from arcgis.gis import GIS import json import sys import arcpy import os os.getcwd gis = GIS(profile='econet') # Step 2: Get the Dashboard Item try: dashboard_id = sys.argv[1] except IndexError: # dashboard_id = "0f3670488cfc4ea19f4a8e22252979fd" # RHB Trapping dashboard dashboard_id = "eafa864b127242b29b0f5d08fc20e017" # PFK Trapping dashboard dashboard_item = gis.content.get(dashboard_id) if not dashboard_item: arcpy.AddMessage("Dashboard not found.

Good idea, but how will it help? I really should look up some logs to see how long it took in ArcMap. Since Esri have turned off my licence for the Pro downgrade I cannot run it now. I really just want normal speed. I have got rid of any BigInteger and BigObjectID fields ( well you have to or CreateRelation() crashes).

The replace layer option in the ArcGISPro share dialog needs exclusive access. It crashes if I also have the layer open in AGOL. That might also be a problem if the layer is being used in Survey123 or FieldMaps. It is also not dynamic. New records will need to be processed. I thought of a virtual field, but that might not be possible. ... View more

A hosted featurelayer of half a million records? I assume it is on your own server, not ArcGISOnline? The storage charges are per 10MB, not per Gigabyte! Have you tried a virtual field(s) in the WebMap? Then you can use Arcade to generate the new fields dynamically.   ... View more

Why are you using shapefiles and excel tables? You would be much better off using a proper database format with tables. Then you can validate the data and control the data schema. It will be faster and more robust. It will handle the difference between blanks and null values. You can use the Microsoft schema.ini file to properly define the schema for the excel spreadsheet before you import it to a database table. Once in a database the keys you are going to use for the table join can be indexed for speed, set to NOT NULL to make sure they are always populated and generally document the schema. The codes with dashes have to be strings, but that may need to be explicitly set. ... View more

It anything takes longer than a cup of coffee, interrupt the process and find a better way! It is likely that it will crash with no results if it has to run for days. To update an online table from ArcGISPro it only works for a few records. If you need a bulk update the best way is to export the table to a local filegeodatabase, do the process on a local machine and then replace the online layer. The replace layer function actually does a Staging Update. This zips up the file and metadata for the layers, uploads and then unpacks in the cloud. This all takes a few seconds or at the most minutes.   ... View more
