When you say add a TextSymbol to the Map and then the user can click on it, this to me is suggesting you have added a TextElement, is that what you meant? Being Devils advocate here, how do you intend to distinguish between text elements you have added to the Map via your code and those added by the user? ... View more

Berend, I think the problem comes from IMapDocument and its method ReplaceContents. It seems to be a method implemented by MapDocument class but not the MXDocument class. Below is some VBA that transfers layers from one MapDocument into the currently running MXDocument. Public Sub TransferLayers()     ''' Get a handle on existing Map Document     Dim pMapDocument As IMapDocument     Set pMapDocument = New MapDocument     pMapDocument.Open "C:\Scratch\Untitled.mxd"        ''' Get a handle on the contents of this Map Document (assumed to be only 1 DataFrame)     Dim pMXDContents As IMxdContents     Set pMXDContents = pMapDocument.Map(0)     Debug.Print pMXDContents.Map.LayerCount        ''' Transfer layers into current MXD     Dim pMXD As IMxDocument     Set pMXD = ThisDocument     Dim pLayer As ILayer     Dim i As Integer     For i = 0 To pMXDContents.Map.LayerCount - 1         Set pLayer = pMXDContents.Map.Layer(i)         Debug.Print pLayer.Name         pMXD.FocusMap.AddLayer pLayer     Next i        ''' Refresh     pMXD.UpdateContents End Sub ...

Melita, Just want to be sure I am crystal clear with understanding this. This change affects 10.3 onwards. All transformations are now referred to as "Composite Transformation" in the Geographic Coordinate System Transformation dialog then a count? So the OSGB_1936_to_WGS_1984_Petroleum is a single transformation and gets a count of 1. I was trying to follow the instructions here​ to use the OSTN02 transformation from Ordnance Survey. They show the text: NTv2 - dataset=uk/OSTN02_NTv2 in the transformations dialog. I was unsure if I had messed up but from reading this thread it is a "cosmetic" issue? Duncan ... View more

Mark, I too have 10.3, just knocked some VBA together to create a progress dialog with a spinning globe and can confirm that when I set it to Globe all I get is a spinning set of dots. Looks like a bug, hope someone from ESRI can confirm this? Duncan ... View more

I think if you are just making an addin then you need only install the ArcObjects sdk for Microsolft .NET Framwork which comes on the install DVD. I have 10.3, that's what I installed and I am using Visual Studio 2012 ​not​ 2013. ... View more

Had to ask! Would this work for you? Run ESRIRegAddIn.exe from a DOS prompt which could be put into a batch file, something like C:\Program Files (x86)\Common Files\ArcGIS\bin\ESRIRegAddIn.exe c:\temp\myaddin.esriAddIn /s The /s is for a silent install Duncan ... View more

Just being devils advocate here, why are you fiddling around with the registry? AddIn's can be installed as Nicola says by double clicking on them or as I prefer I add the folder where the AddIn is via the Add-in Manager dialog. Very simple no pain? ... View more

Just want to say this would be really useful. I find it a pain having to move to ArcCatalog to find out the size especially as I use personal geodatabases to store data that I intend to say move into a stats package. Personal geodatabases have that 2GB limit so its very useful to keep an eye on its size.  A big reason to use the Catalog window in ArcMap was to avoid file locking but it does not give us all the information we need and forces us to open ArcCatalog all the time...  ...

This is a nifty way, I like that! ... View more

I still think using the Feature vertices to point tool is your easiest option but I got interested in the idea of writing it as cursors and accessing geometries. I knocked some code together but it failed. I ran your sample data through the repair geometry tool and re-ran the code and it still failed. I then took a closer look at your data and discovered it does not conform to the definition of polygons with interior rings. Part zero should be the EXTERIOR ring and CLOCKWISE. In your data what looks like the exterior ring is the interior ring! Each ring has the correct orientation but is the wrong part number. Create a polygon with a hole in it in ArcMap and everything is as expected and the code runs spewing out XY for interior rings. So it's not your code that is at fault it is the data and the software that generated it. It looks like what ever created it has built the polygon in to out rather than out to in. ... View more

If you intend to use a python approach in ArcGIS and you look at Neil's idea you still need to import arcpy to use the cursors. If you are importing arcpy then why make lots of work for yourself when you can simply call the tool to do it! The only reason you would want to do it using cursors and accessing geometries is if you do not have an Advance license. You should state what your license level is in any question as this dictates what sort of solution you will get. ... View more

I've just downloaded your data and ran it through the Feature vertices to Points tool which is an Advance licensed tool and this extracted out to a new dataset all vertices, including those of the inner ring. So it works for me... ... View more

I don't think it works like that. If you have typed arcpy then dot and can then see a drop down from which you can choose Describe then the intellisense is working. Beyond that it does not work as I guess describe can return many types of very different objects based upon the value you supply to it, so how is it supposed to know? ... View more

Thomas, Agree ESRI support can be frustrating especially if you want to fire off a potential bug in the software. But for your problem here is a simple work around, don't try to get the length of the list when you want to identify if your layer had a selection. That's obviously a weird bug as a list with an empty string is an odd thing to return. I would simply do this: if len(arcpy.Describe("Field Sites").fidset) > 0:     print "You have a selection" else:     print "No features selected" Duncan ... View more
