Bruce? Who is this Bruce? I'm Duncan! 😄 I've created a COM Class and exposed a method called StartEditing. So in Access I create an instance of this and call the method, passing in the IApplication object. In this method code it gets a handle on the Editor and starts the Edit session for the specified workspace: pEditor.StartEditing(pWorkspace) I have an Extension that is listening for edit events and writes an ID which was written to a dockable window to the feature. So all the editing is done in ArcMap I "just" intercept the edit event. I have to test if I am actually in an MXD with the required layers or just a new blank mxd that a user happened to open up. So my Visual studio solution contains two projects, one that is the AddIn extension and another project that creates my DLL with my COM Class, it's this one I reference in Access. ... View more

I am working on a project where Acccess drives ArcMap and vice versa. My code in Access starts a session of ArcMap (sounds like you have done that) and zooms to a feature. I have an extension that listens out for edit events. I created a COM object which compiles to a DLL and is referenced by Access which starts the edit session so this is how I pass an ID to the application. It's important to realise this is not an AddIn but a COM class. Another (and probably easier) method is in your other application you write your information to a specified location and your edit event looks there. As for best practise, that to me is the one that works first and is easiest to develop so hopefully easy to maintain... ... View more

Evan, I just tried to replicate your problem in VBA and it returns Nothing, which leads me to think you have discovered a bug. I thought the approached discussed here may work but that returns Nothing to. I reckon ESRI have broken this interface as this thread I link to has no discussion about the Messages object. Duncan ...

I think the solution to this is to point your IT department to this site and shame them for not allowing you to work efficiently (by download that script you refer to).  They are there to serve your organization not put up barriers... Sorry to hear you work in an unhelpful and restrictive business environment. ... View more

I agree, this would be extremely difficult to implement especially across multiple networks.  Whilst your idea is a good one I believe it is not viable. I had to restructure a clients GIS system a year a go and I looked at the voyager software on this web site as a means of answering that very same question. I played around with the demo version, it appears to offer the solution you require if your are willing to spend the money. But it was outside the budget of the project and now arcpy offers the ability to extract such information from MXD's and workspaces I wrote a script that trawled their GIS folder creating text files of whats in what and it was a matter of querying this files. You also get into the nutty situations like users adding the same dataset to a MXD but with different featurelayer names or duplication of a dataset across multiple projects folders, exactly the sort of think you are trying to clean up. ...

You could try putting an attribute index on your field selectedFieldName or abandon the approach you are using and call the summary statistics tool, may be writing the output to a temporary in_memory workspace? ... View more

It seems the only tool that allows you to select the field to reclassify in the raster is the Reclassify tool. If you look at the interface it allows you to load previously saved remaps but it appears to save them out as info tables. So... Looks like you'll have to do this using python. Look at the help page on the reclassify tool, this shows an example. It would not be too hard to read your ascii file into the remap table object. ... View more

This is why I parse the output of the iterator to get the shapefile name so c:\temp\fred.shp will parse to "fred". I then use inline substitution to grab the equivalent raster from c:\raster\fred.tif. ... View more

This can all be done in model builder no need to create a python script. You need to read the help file about iterators and inline substitution. Read those pages to understand the model below which will do what you want. [ATTACH=CONFIG]33864[/ATTACH] ... View more

I gues you could call the FeatureClass to FeatureClass tool to copy the dataset into the FeatureDataset? This page has a section called Converting and transferring data. ... View more

What do you mean by overlap, you do not explain what these numbers represent? Are they ID's or some sort of measurement? ... View more

Move this line: Dim queryFilter As IQueryFilter = New QueryFilterClass() above this line Do While pEnum.MoveNext This should improve performance as you do not need to keep creating this object. You only need to create it once and update the whereclause. ... View more
