To minimize the overhead I am asking an Oracle database table only for specific objects through the OpenTable method. While it works with in the first attempt, all others fail. I do not know what the issue is but I am getting an ArcGIS.Core.Data.GeodatabaseQueryexception thrown when trying to open the table based on my query description. Below is the code how I am trying to get the data. The exception thrown is pointing to "Geometry is null geometry" which is strange since I can find multiple objects that fulfil the SQL statement. public async void SearchValidationTables() { await QueuedTask.Run(() => { using (Database ValidationDatabase = new Database(connectionFileValidation)) { // get national string prefix string nationalStringPrefix = ""; SQLSyntax sqlSyntax = ValidationDatabase.GetSQLSyntax(); nationalStringPrefix = sqlSyntax.GetSupportedStrings(SQLStringType.NationalStringPrefix).First(); // build query here and set it into next line string querySQL = "SELECT * FROM SCHEMA.DBTABLE WHERE FEATURETYPE = "+ nationalStringPrefix +"'waterways'"; QueryDescription queryDescription = ValidationDatabase.GetQueryDescription(querySQL, "test"); // set the column with a unique identifier queryDescription.SetObjectIDFields("OBJECTID"); // get data as featureclass and load it as featurelayer try { FeatureClass fcFromTable = ValidationDatabase.OpenTable(queryDescription) as FeatureClass; LayerFactory.Instance.CreateFeatureLayer(fcFromTable, MapView.Active.Map); } catch (GeodatabaseQueryException e) { throw e; } } }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I found a bit more information by looking at the inner exception: Does that mean I have to adjust the QueryLayerName? ...

I need to provide my clients with the possibility to select a GDB from within a DockPaneView. Now that I found out on how to get the parentWindow to satisfy the SelectFolder method I have to realize I cannot set the initialPath attribute. The method expects a string but writing "c:\\" still opens the dialog in the users home directory. I found that I should be able to set the path to a sub-directory of the users home directory by writing e.g. "~/Documents". Nothing off this works. I always start in the users home directory. But what I want is the possibility for the user to store the selected path in my solution as a resource variable and next time the SelectFolder dialog is opened the resource variable should retrieve the initial path from the resource file. Has somebody a working example on how to set the initialPath attribute? As said, the functionality is required to work from within a DockPaneView (WPF). Best Thomas ... View more

I have to write an add-in for our technicians where in a dockpane I want to show the total amount of features in the layer. So far I only found how to get the count of selected features, but that doesn't help me, since I don't want to run a 'select all' every time there is something going on at the side of our technicians. In Python there is a getCount method. Is this function available in C# as well. Bests Thomas ... View more
