Hi Guys.  I am creating an extension for ArcMap 10.2 using Visual Studio 2012 C# WPF.  Consider this code snippet: //Open the CSV file IWorkspaceFactory WorkspaceFactory = new TextFileWorkspaceFactoryClass(); IFeatureWorkspace FeatureWorkspace = (IFeatureWorkspace)WorkspaceFactory.OpenFromFile(FilePath, 0); ITable Table = FeatureWorkspace.OpenTable(FileName); IStandaloneTable StandaloneTable = new StandaloneTableClass(); StandaloneTable.Table = Table; IMap Map = MxDocument.FocusMap; IStandaloneTableCollection StandaloneTableCollection = (IStandaloneTableCollection)Map; StandaloneTableCollection.AddStandaloneTable(StandaloneTable); //Create the Event Layer of the data source IDataset Dataset = (IDataset)StandaloneTable; IName TableName = Dataset.FullName; IXYEvent2FieldsProperties XYEvent2FieldsProperties = new XYEvent2FieldsPropertiesClass(); XYEvent2FieldsProperties.XFieldName = ColumnX; XYEvent2FieldsProperties.YFieldName = ColumnY; XYEvent2FieldsProperties.ZFieldName = String.Empty; IXYEventSourceName XYEventSourceName = new XYEventSourceNameClass(); XYEventSourceName.EventProperties = XYEvent2FieldsProperties; XYEventSourceName.EventTableName = TableName; XYEventSourceName.SpatialReference = SpatialReference; IName XYEventName = (IName)XYEventSourceName; IXYEventSource XYEventSource = (IXYEventSource)XYEventName.Open(); //Map the Event Layer IFeatureLayer FeatureLayer = new FeatureLayerClass(); FeatureLayer.FeatureClass = (IFeatureClass)XYEventSource; FeatureLayer.Name = FileName; //Add the layer extension (this is done so that when you edit the layer's Source properties and click the Set Data Source button, the Add XY Events Dialog appears) ILayerExtensions LayerExtensions = (ILayerExtensions)FeatureLayer; LayerExtensions.AddExtension(new XYDataSourcePageExtensionClass()); //Add it to the MXD Map.AddLayer(FeatureLayer); FeatureLayer.Selectable = true; MxDocument.UpdateContents(); MxDocument.ActiveView.Refresh(); This is from a function in a class that is called from the UI Form.  What I am doing is creating a CSV file from a .Net DataTable (not in the above code), adding the CSV as a Table in Sources of the TOC, and them mapping the Table as Layer (the last 4 lines above).  This all works fine if I do it on the main UI thread of the Form when the user clicks a button.  But what I would like to do is it put it on a TPL thread since it can be a time consuming process and here is when I run into problems.  The above code will CRASH arcmap completely.  It cannot even be trapped. I noticed two things.  One, the crash happens on the line "Map.AddLayer(FeatureLayer);" so when it tries to add to the layer.  So I removed that line just to see what the Table in sources looks like.  Second, looking at that Table I notice that if I right click it the options to Open and Display are lit-up for a second and then grey out.  Again, this only happens when on a Thread. Another thing to note is that when I break on any of the lines of code above in the Thread and inspect the objects I get an error "The function evaluation requires all threads to run".  I would think this is more an issue with Visual Studio and the implicit evaluation settings so it should not affect arcmap and it certainly should not cause it to crash.  But I thought I would mention it. Thanks for any help. Ernie ... View more

Hi Everyone.  We finally upgraded to AGS 10.1 and are switching over our web services.  One issue I am running into is using the layers as WMS with a Proxy file (one of many error actually but I have gotten around the others).  Using SL 5 and version 3.1 of the API (also tried this with SL 4 and api 3.0 but upgraded to see if it made a difference). Prior to 10.1, I had a bunch of different layer types load in our SL app - Dynamic, Tiled and WMS.  Also had a proxy file sitting on the same server in the the app (ie ./Proxy/proxy.ashx and proxy.config).  Everything worked fine, I added url stems to the proxy file with a match all set.  So for example: <serverItem url="http://serverx/" matchAll="true" /> In this case the layer did not have security turned on but we have to add an entry for it anyway - which worked fine.  Now, with 10.1, I keep getting a "not found" error bounce back from the WMS layer.  I tried adjusting for the port with something like this but no dice: <serverItem url="http://serverx:6080/" matchAll="true" /> Fidder comes back with this: Non-negative number required. Parameter name: count Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentOutOfRangeException: Non-negative number required.

Hi Guys. I am working an an extension for ArcGIS Desktop in Visual Studios and .net 4.0.  I Have created a working shell with a few buttons and some basic code to make sure everything will work as I like and am stuck on one last thing. I would like to add a combo box to the toolbar (like the Map Scale drop down in the "Standard" toolbar of arc).  I found the form-based sample solution provided by ESRI called GraphicsLayerToolControl which has been a big help. But here is where I am stuck.  I am trying to do it all in WPF and the MVVM pattern.  I created a UserControl like in the sample but when I try to complete the command class for it I cannot properly build the required hWnd property.  Since this is WPF there is no native handle to be had.  I thought I could use the Interop function HwndSource.FromVisual to get it but that comes back null.  I think the problem is there is no equivalent "CreateControl()" function in WPF that the forms-based example relies on to force creation of the control  This is what that looks like:     public int hWnd     {       get       {         //pass the handle of the usercontrol         if (null == m_graphicsLayerListCtrl)         {           m_graphicsLayerListCtrl = new GraphicsLayersListCtrl();           m_graphicsLayerListCtrl.CreateControl();  //CANNOT FIND ANYTHING SIMILAR IN WPF         }         return m_graphicsLayerListCtrl.Handle.ToInt32();       }     } Is there a way to make this work or am I forced to do a forms-based usercontrol?

Hi Guys. With a new extension I am creating in ArcMap using Visual Studios, I want to be able to save user settings in the user.config file.  Using the built in functionality of VS, I get this as a path to user.config when I do my first save: C:\Users\<USERNAME>\AppData\Local\ESRI\DefaultDomain_Path_csldzz....\10.1.1.3143\user.config The part that is after Local is what I am concerned with.  The ESRI is the company name which is used, I assume, because the extension is actually ran in ArcMap so even thought I have a company created in the extension it will use the EXE's company.  After the company name is what I am really curious about.  It is suppose to be based on  <App Name>_<Evidence Type>_<Evidence Hash>\<Version>.  Where does "DefaultDomain" come from?  I assume somewhere in ArcMap but can that be changed without having to modify Arc itself?
