At now the ITableSort interface can only be used to sort tables that have an ObjectID field. Obviously any table can be sorted by some field, sorting should not require any specific field to proceed. It would be great if this limitation of the ITableSort will be removed. ... View more

I'm building an ArcMap extension. In its Startup method I subscribe to IApplicationStatusEvents.Initialized event. In handler of this event I use some methods of GPUtilities class: public class SomeExtension : IExtension {     #region COM Registration Function(s)     [ComRegisterFunction]     [ComVisible(false)]     private static void RegisterFunction(Type registerType)     {         ArcGISCategoryRegistration(registerType);     }     [ComUnregisterFunction]     [ComVisible(false)]     private static void UnregisterFunction(Type registerType)     {         ArcGISCategoryUnregistration(registerType);     }     #region ArcGIS Component Category Registrar generated code     /// <summary>     /// Required method for ArcGIS Component Category registration -     /// Do not modify the contents of this method with the code editor.     /// </summary>     private static void ArcGISCategoryRegistration(Type registerType)     {         string regKey = string.Format(CultureInfo.InvariantCulture, "HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID);         MxExtension.Register(regKey);     }     /// <summary>     /// Required method for ArcGIS Component Category unregistration -     /// Do not modify the contents of this method with the code editor.     /// </summary>     private static void ArcGISCategoryUnregistration(Type registerType)     {         string regKey = string.Format(CultureInfo.InvariantCulture, "HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID);         MxExtension.Unregister(regKey);     }     #endregion     #endregion     // ...     void IExtension.Startup(ref object initializationData)     {         // ...         var application = initializationData as IApplication;         bool initialized = true;         var applicationStatus = Application as IApplicationStatus;         if (applicationStatus != null)             initialized = applicationStatus.Initialized;         var applicationStatusEvents = Application as IApplicationStatusEvents_Event;         if (applicationStatusEvents != null && !initialized)             applicationStatusEvents.Initialized += ApplicationInitialized;         else             ApplicationInitialized();         // ...     }     private void ApplicationInitialized()     {         // ...         var gpUtilities = (IGPUtilities3)Activator.CreateInstance(Type.GetTypeFromCLSID(typeof(GPUtilitiesClass).GUID));         IGPParameter gpParameter = new GPParameterClass();         gpUtilities.PackGPValue(new DEFeatureClassClass(), gpParameter); // This line causes Metadata tools are broken         // ...     }     // ... }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Steps to reproduce the problem: open ArcMap with closed or folded (not pinned) ArcToolbox window; open AcrToolbox; now all tools from the Metadata toolset are broken (they have red cross icon and cannot be opened and executed). But if on the first step you open ArcMap with opened and shown ArcToolbox then everything is fine, Metadata tools are valid and can be executed. If I comment line #74 in the code snippet above then everything is fine too. It seems that GPUtilities must be used only after ArcToolbox is shown. This strange behavior started to appear with ArcMap 10.4. So 10.4, 10.4.1 and 10.5 has this problem. In 10.3.1 all is OK. I believe that this is bug on ArcGIS side, so I really hope that it will be fixed. I didn't find any workaround for this issue. Maybe with 10.4.1 I need to execute some magic code before I can use GPUtilities so Metadata tools will not be broken? ... View more

Hi, I'm building custom geoprocessing tool where output value can be feature class or table with GPFeatureSchema as default schema. But the type of an output dataset depends on some option. In tool's UpdateParameters method I change schema of the output parameter to GPTableSchema or to GPFeatureSchema. But in Model Builder any tool after the my one always thinks that my tool produces feature classes. Is it possible to dynamically change type of schema so chained tools get right output information from my tool? ... View more

I found that PolylineBuilder throws the AccessViolationException when the builder is used after multiple Dispatcher.Invoke calls. If I use BeginInvoke instead of Invoke, everything goes fine, so it is the workaround. But I believe you should fix this problem. I've attached VS solution with simple test add-in (TestAddIn.zip) and test data (test.gdb.zip, place it in Debug folder after solution building). This test add-in contains one button (Click Me!) which opens a dialog. In this dialog click the Start button and you'll get AccessViolationException at line #35 in FeatureClassIterator.cs file. ...
