Colin, Funnily it seems that it was the missing QueuedTask.Run that produced the null RowCursor. I didn't use it because the ProConcepts Geodatabase · Esri/arcgis-pro-sdk Wiki · GitHub page says "you can create a QueryFilter on a non-MCT thread". (a concept I don't fully understand yet). Many thanks, Andres ... View more

Thank you Colin, First this happens:         private async Task AddLayerToMap(string layerPath, string layerField, string layerFileName)         {             try             {                 // Get the first map called "Map" from the current project.                 Map myMap = null;                 myMap = await GetMapFromProject(Project.Current, "Map");                 if (myMap == null)                 {                     ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Failed to get map.");                     return;                 }                 await QueuedTask.Run(() =>                 {                     SelectedLayer = MapView.Active.Map.FindLayers(layerFileName, true).FirstOrDefault() as FeatureLayer;                     if (SelectedLayer == null)                     {                         SelectedLayer = LayerFactory.CreateFeatureLayer(new Uri(layerPath), myMap);                     }                     MapView.Active.ZoomToAsync(SelectedLayer);                     if (SelectedLayer == null)                     {                         ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Failed to create layer for url:" + layerPath);                         return;                     }                     else                     {                         var queryFilter = new QueryFilter();                         queryFilter.PostfixClause = "ORDER BY " + layerField;                         var rc = SelectedLayer.Search(queryFilter);                         FieldList.Clear();                         while (rc.MoveNext())                         {                             using (Feature feature = (Feature)rc.Current)                             {                                 string name = Convert.ToString(feature[layerField]);                                 FieldList.Add(name);                             }                         }                     }                 });             }             catch (Exception exc)             {                 ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Exception caught: " + exc.Message);                 return;             }             FieldListBox.Items.Clear();             foreach (string ListItem in FieldList) { FieldListBox.Items.Add(ListItem); }         } Then this:        void NameFilterBox_KeyUp(object sender, KeyEventArgs e)         {             TextBox source = e.Source as TextBox;             NamePart = source.Text;             QueryFilter queryFilter = new QueryFilter();             if (NamePart == "")                { queryFilter.WhereClause = ""; }             else                { queryFilter.WhereClause = layerField + " LIKE '%" + NamePart + "%'"; }             queryFilter.PostfixClause = "ORDER BY " + layerField;             RowCursor rc = SelectedLayer.Search(queryFilter); // <- returns null !!!             //Create list of oids to update             while (rc.MoveNext())             {                 using (Feature feature = (Feature)rc.Current)                 {                     string name = Convert.ToString(feature[layerField]);                     FieldList.Add(name);                 }             }         } ...

Thank you Charles.  Yes, myMap is the MapView.Active.Map and RefLayer.Name is the layerName. Your questions helped me find out what the problem was: I was handling the creation in a queued task and FindLayers outside that task. I'm new to C# so I haven't really grasped how the queued tasks work. Thanks again! ... View more

What is theMapPoint? Is it a point selected from the map? If so, that's not what I need. I need a way to convert geographic coordinates into MapPoints. ... View more

I am creating a tool that would zoom in on specific geographic points. My idea is to have the list of geographic points with their geographic coordinates which the tool should convert to the current map mappoints, but as said I'm a bit clueless on how to go about. ... View more

Thank you Charles, but neither is what I'm looking for. I want the text file to be external to the Addin so that the lines (each line is an item) can be edited (customized) by each Addin user. The users won't have Visual Studio to access and edit any embedded resource. The "Access Content" link you sent me has a similar concept to what I want which is to get the path where the Addin is located in run time that would then be useful to access the Addin accompanying text file. However it is reading the assembly path and not the actual location of the distributed Addin. ... View more

Thank you Wolfgang. I checked your code and the WorkingWithDALM example, but both are different cases to what I'm trying to do. I'm using: ...       </controls>     </insertModule>     <updateModule refID="MyAddin1_Module">       <tabs>         <updateTab refID="MyAddins_Tab">             <updateGroup refID="Layer_Group"></updateGroup>         </updateTab>       </tabs>     </updateModule>   </modules> </ArcGIS> to try to have a second button within the same group of the first app. I made sure both were working and that the first one loads first. The second Add-in has the same module, tab and group id as the first one. What is wrong here? Is there a reference document on the config.daml file? ... View more

That's very kind of you Charles. Right after posting this, I realized how foolish the question is and would have deleted it if I could. I was using a very long UNC path and made a mistake typing it. ... View more
