Trying to work my way through my first add-in. One thing I am struggling with is user inputs. I have a DockPane where the user can input a path to their output feature class and the coordinate system of the output. The user can input their desired data either by typing in the textbox or using the browse functions to fill that in for them. My struggle is to convert the contents of the textbox to usable objects. For example, after the user either types in their coordinate system or uses the CoordSysDialog to choose it then how do I convert the result to a SpatialReference object?  Same thing with the output feature class. From the textbox how do I determine if the feature class is a shapefile or a feature class in a geodb? What are the best practices for these types of inputs? I see them in the ArcGIS Pro geoprocessing tools so there must be some way to validate each one and the proper type. ... View more

So I just started with a Pro add-in and have added a DockPane. The user fills in input and I send that to a geoprocessing function. In the DockPane I have a button with a click event Private Sub btnGo_Click(sender As Object, e As RoutedEventArgs) Handles btnGo.Click    Try       'collect WPF form info       DoGp(info)    Catch ex As Exception       MessageBox.Show(ex.Message, "Exception", MessageBoxButton.OK, MessageBoxImage.Error)    End Try End Sub In a separate module I have Public Async Sub DoGp(ByVal vg As Info) Try    Dim toolPath As String = "management.CreateFishnet"    Dim progDlg As ProgressDialog = New ProgressDialog("Running Geoprocessing Tool", "Cancel", 100, True) progDlg.Show()    Dim progSrc As CancelableProgressorSource = New CancelableProgressorSource(progDlg)    Dim res As IGPResult = Await Geoprocessing.ExecuteToolAsync(toolPath, params, envr, progSrc.Progressor, GPExecuteToolFlags.Default)    progDlg.Hide()    If res.IsFailed Then Throw New Exception("Geoprocessing tool failed.") Catch ex As Exception    Debug.Print(ex.ToString)    Throw  'crashes here End Try End Sub When I run it and there is an error in the output there is an unhandled exception at the line Throw: An exception of type 'System.Exception' occurred in MyAddin.dll but was not handled in user code Geoprocessing tool failed. I have Try-Catch in the calling code and also in the module so why is it not propagated? ... View more

I've been looking at some posts and don't quite get how to incorporate a coordinate system dialog in my add-in. This post implies that ESRI has provided a built in control Custom spatial references in the coordinate system control. This post implies that I have to compile an add-in How to capture none in Current Z for CoordSysDialog. Im confused as to how to use the control in my add-in. Any help appreciated. ... View more
