Alexander, Just an idea but have you tried calling the Copy geo-processing tool to copy the workspace? Duncan ... View more

If you place the AddIn in a folder that all users can reach (e.g. a sub-folder in the ArcGIS folder) then all users can log in under their own profile and navigate to it. If it is on a network drive then all users could navigate to it from any computer with ArcGIS... ... View more

John, I have not used this interface so it may be a red herring but take a look at the IConversionNotation interface? Duncan ... View more

Mickey, I don't believe there is a method or property that returns the answer to "does this layer belong to a group layer, if so which". You would need to create a recursive procedure that searches the layers and traverse down the tree of layers testing the type of layers you are finding. Below is a bit of VBA that shows you how to test the type of layer found. You need to create a recursive procedure around this logic. Public Sub test()        Dim pMXDocument As IMxDocument     Set pMXDocument = ThisDocument     Dim pMap As IMap     Set pMap = pMXDocument.FocusMap     Dim pEnumLayer As IEnumLayer     Set pEnumLayer = pMap.Layers(Nothing, True)     Dim pLayer As ILayer     Set pLayer = pEnumLayer.Next     Do While Not pLayer Is Nothing         If TypeOf pLayer Is IGroupLayerayer Then             Debug.Print "GroupLayerayer = " & pLayer.Name             ' Do a recursive search here         ElseIf TypeOf pLayer Is IGeoFeatureLayer Then             Debug.Print "FeatureLayer = " & pLayer.Name         End If         Set pLayer = pEnumLayer.Next     Loop End Sub Duncan ...

You say you are making a stand alone application, I assume you are using Engine? I looked at the help for the IMaps interface and in the remarks it says: ... IMaps interface is NOT available with ArcGIS for Server and ArcGIS Engine since this interface is used to get access to a Maps object, which is a non-creatable object. References to non-creatable objects must be obtained through other objects. IMaps interface is available only with ArcGIS for Desktop. Your code is accessing an MXDocument class? Have you considered using a MapDocument object instead? Look a the help page "Working with map documents" there is a section about why you would use a MapDocument class instead of an MXDocument Class. Worth a read? Duncan ... View more

Just thinking off the top of my head here but could you have a very simply text file which lists paths to other locations and include that into the AddIn. Then your AddIn code looks for this file and reads from it allowing you to store your data elsewhere? I have not used Python AddIns so not sure how easy it would be to include a separate file? ...

If your source dataset has ZM values (even if they are not set) and you want to drop these from the entire dataset you will have to export the dataset to a new FeatureClass which does not support ZM values. If you want to achieve this in ArcObjects the easiest way is probably to call the geo-processing tool using the execute method on the IGeoProcessor object. ... View more

Jacob, Glad to have helped, but you should mark your post as answered. Also if you see a good question/answer vote it up! People love you for it. Duncan ... View more

Your calculate expression is invalid, you have: "[Shape_Length * 2] / [Join_Count]" it should be: "[Shape_Length] * 2 / [Join_Count]" Duncan ... View more

Accessing the point collection using an index makes a lot of sense to me but I totally agree the Help for this method is about as clear as mud. ESRI need to improve this with proper examples. ... View more
