I would assume that there is something different between your solver in ArcMap and your solver in your standalone python application. I would suggest running your standalone code in the python window of a new blank session of ArcMap so that you can verify the data in the same environment. ... View more

As an alternative to the try/catch approach you could just check if the layer supports datasource. import arcpy import os import sys from arcpy import mapping as m arcpy.env.workspace = r"C:\Project" counter = 0 for mxdPath in arcpy.ListFiles("*.mxd"):     print(mxdPath)     mxd = m.MapDocument(mxdPath)     df  = m.ListDataFrames(mxd, "Layers")[0]         for lyr in m.ListLayers(mxd, "", df):         if not lyr.supports("DATASOURCE"):             continue                 if lyr.dataSource == r"D:\PROJECTS\zfonGivatShmuel\gis\layers\6_9_15\gvul.shp":             m.RemoveLayer(df, lyr)             print("Remove")     mxd.save()     del mxd ...

Would you be able to upload a small sample of your data, a map document with your solved od cost matrix layer,  and script that I can use to take a closer look at this? ... View more

You'd need to use a geodatabase feature class instead of a shapefile to accomplish this. Shapefiles do not support NULL values. This is documented on the following page: Add Field (Data Management) http://desktop.arcgis.com/en/desktop/latest/tools/data-management-toolbox/add-field.htm As shown in the screenshot below, Null values are only supported for fields in a geodatabase. ...

That portion of the code is about using Dictionaries. You can read up on this concept on the following page: C# Dictionary http://www.dotnetperls.com/dictionary This is a data structure in .NET that is not related to ArcObjects. Think of it like an actual dictionary. In a dictionary a word (i.e. key) will be defined once and the definition (i.e. value) will consist of multiple words, which can be repeated. I used the name of the feature dataset as the key in the dictionary and used the names of the feature classes as the values so that I easily organize which feature classes were in which feature dataset and print out a "prettier" list of the results.  If you want you could simplify this logic as follows: ILayer layer; //    while ( (layer = enumLayer.Next()) != null) //    { //        var fc = (layer as IFeatureLayer).FeatureClass; //        if (fc.FeatureDataset != null) //        { //            if (results.ContainsKey(fc.FeatureDataset.Name)) //                results[fc.FeatureDataset.Name].Add(fc.AliasName); //            else //                results[fc.FeatureDataset.Name] = new List<string> {fc.AliasName}; //        } //        else //            Console.WriteLine("Skipping {0}...NOT within a Feature Dataset", fc.AliasName); //    } //} //foreach (var kvp in results) //    Console.WriteLine("FEATURE DATASET: {0}\n...{1}\n", kvp.Key, String.Join("\n...", kvp.Value)); while ((layer = enumLayer.Next()) != null) {     var fc = (layer as IFeatureLayer).FeatureClass;     if (fc.FeatureDataset != null)         Console.WriteLine("FEATURE CLASS: {0,-20} | FEATURE DATASET: {1}", fc.AliasName, fc.FeatureDataset.Name); } Below are screenshots of the results of these two options. ** Option A : using dictionary ** ** Option B ** ...

I just downloaded the tools and it appears to come with an installer that registers the toolbar with the various commands, tools, etc. To use this tool in python you'd need access to the source code of the tools so that you could wrap their logic as functions that you could either leverage in a variety of ways. Have you tried contacting the US Forest Service to determine if they'd be willing to expose the source code for this toolbar? ... View more

You should be able to check if cast the layer to IFeatureLayer and then check if the FeatureLayer.FeatureClass.FeatureDataset is equal to null. If it is null then the dataset is not within a feature dataset. I would assume that your code would fail on the call the pDataset.Name when the dataset is not within a feature dataset because the call to pFeatureClass.FeatureDataset will be null. Below is the code I used to confirm along with a sample that will display this for you. using System.Collections.Generic; using ESRI.ArcGIS.Carto; using ESRI.ArcGIS.esriSystem; using System; using System.IO; using System.Reflection; namespace ListFeatureDatasets     class Program     {         private static readonly LicenseInitializer m_aoInit = new LicenseInitializer();         private static readonly String m_srcPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);         private static readonly String m_mxdPath = Path.Combine(m_srcPath, @"data\SanDiego.mxd");             [STAThread()]         static void Main(string[] args)         {             //ESRI License Initializer generated code.             m_aoInit.InitializeApplication(new [] { esriLicenseProductCode.esriLicenseProductCodeAdvanced }, new esriLicenseExtensionCode[] { });             var mxd = new MapDocumentClass();             mxd.Open(m_mxdPath);             Dictionary<string, List<string>> results = new Dictionary<string, List<string>>();             for (int i = 0; i < mxd.MapCount; i++)             {                 var map = mxd.Map;                 var uid = new UIDClass {Value = "{40A9E885-5533-11D0-98BE-00805F7CED21}"}; // IFeatureLayer                 var enumLayer = map.Layers[uid, true];                 enumLayer.Reset();                 ILayer layer;                 while ( (layer = enumLayer.Next()) != null)                 {                     var fc = (layer as IFeatureLayer).FeatureClass;                     if (fc.FeatureDataset != null)                     {                         if (results.ContainsKey(fc.FeatureDataset.Name))                             results[fc.FeatureDataset.Name].Add(fc.AliasName);                         else                             results[fc.FeatureDataset.Name] = new List<string> {fc.AliasName};                     }                     else                         Console.WriteLine("Skipping {0}...NOT within a Feature Dataset", fc.AliasName);                                     }             }             foreach (var kvp in results)                 Console.WriteLine("FEATURE DATASET: {0}\n...{1}\n", kvp.Key, String.Join("\n...", kvp.Value));             Console.WriteLine();             Console.Write("Press enter to exit...");             Console.ReadLine();             //ESRI License Initializer generated code.             //Do not make any call to ArcObjects after ShutDownApplication()             m_aoInit.ShutdownApplication();         }     } } ...

You should be able to change the sources of your layers using logic shown on the following page. How to change the data source of a layer http://help.arcgis.com/en/sdk/10.0/vba_desktop/conceptualhelp/index.html#//0001000000m5000000 I would think if you wanted this to all happen when the map document is loaded that you'd want to implement this within an application extension where you'd need to incorporate logic on how to determine which geodatabase version to connect to.

Hi Thomas, You are correct. The Visual Editor project was deprecated. I believe that if you want to use the ArcObjects pallette you'd need to use the WindowBuilder project. Once you have WindowBuilder installed you should be able to import the arcobjects.jar and gain access to the needed Visual Beans. ... View more

Did you try deploying the jar using one of the following deployment methods? Copy the .jar file to the ARCGISHOME/java/lib/ext folder. This ensures that the extension gets automatically registered with ArcGIS the next time the application is started. This is a Java-friendly way and a recommended practice for deploying all ArcGIS extensions. Explicitly register the .jar file with ArcGIS either through the API exposed on the com.esri.arcgis.interop.extn.RegTool class or through the "regtool.bat"/"regtool.sh" script available under ARCGISHOME/java/tools.
