Hi all: I'm having difficulty trying to programatically access the data source for layers within an mxd.  Code follows: DirectoryInfo di = new DirectoryInfo(folder);             FileInfo[] files = di.GetFiles("*.mxd");             Dictionary<string, List<String>> referencedFiles = new Dictionary<string,List<string>>();             foreach (FileInfo fi in files)             {                 referencedFiles.Add(fi.FullName, new List<string>());                 IMapDocument doc = new MapDocument();                 doc.Open(fi.FullName);                 doc.SetActiveView(doc.PageLayout as IActiveView);                 doc.ActiveView.Activate(0);                 IEnumLayer pEnumLayer = doc.ActiveView.FocusMap.Layers;                 pEnumLayer.Reset();                                 ILayer pLayer;                 while ((pLayer = pEnumLayer.Next()) != null)                 {                     IFeatureLayer pFL = pLayer as FeatureLayer;                     IFeatureClass pFC = pFL as IFeatureClass; // pFC is coming up null every time for all shapefile layers.                 }             } Hi, Try this public static string GetPath(IApplication pApplication)        {             IMxDocument pMxDoc;             pMxDoc = pApplication.Document as IMxDocument;             IMap pMap;               pMap = pMxDoc.FocusMap;                        IFeatureLayer pFeatLayer;            IDataset pDataset;            pFeatLayer = pMap.get_Layer(0) as IFeatureLayer;            pDataset = pFeatLayer.FeatureClass as IDataset;            string strFilePath = "";          strFilePath = pDataset.Workspace.PathName;          return strFilePath;        } ...

We currently use ZigGIS. We were hoping for native support without the use of ArcSDE and native ArcCatalog read/write management support. I suppose it is a little too much to ask for. We use PgAdmin to manage.  ZigGIS for the Read/Write of postgis features in ArcGIS. Actually we find we use ArcGIS less for Analysis work, and more for the pretty map making tools. Do you work all editing using GigGIS ? is GigGIS is free ? Will you compare  PostGIS and ArcSDE.when you use in ArcGIS ? ... View more

Dear Venkat, Thank you so much for the answer. It�??s really helpful Sure. The code you have developed is working perfectly. 1. how to develop the code so that we don�??t need: �?� To work in edit session. �?� To have the field �??name�?� in the district layer. 2. How to develop the code considering the following approach: �?� to intersect the two layers (districts and hospitals: both are polygons) �?� And then to make summery in the table of the resultant layer (from the intersection) so that we count all the hospitals in each district. I�??m supposed to print the result in the form and then to be able to export it to a table to excel Please, see the attached file Appreciated Kalid Hi, Whatever the code i have given is the intersect two poly and point layers and count the point within the polygon and add into polygon layer table ...and below is that thread where you can find the code for exporting into excel...Please change the code as per your requirement. http://forums.esri.com/Thread.asp?c=93&f=992&t=227281&mc=6#msgid692161 ...
