Hi everybody,
I have to write an console application, that creates an lyrx-File of a wms-service.
I should be able to create a Layer using the Layer Factory, but it needs a map.
So I try to Create an empty Map first.
When I do, I get an Exception:
System.NullReferenceException
HResult = 0x80004003
Nachricht = Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
Quelle = ArcGIS.Desktop.Mapping
Stapelüberwachung:
at ArcGIS.Desktop.Mapping.MapFactory.<>c__DisplayClass5_0.<CreateMap>b__0()
at ArcGIS.Desktop.Internal.Mapping.Utilities.MakeBasicServiceCall[T](Func`1 serviceCall)
at ArcGIS.Desktop.Mapping.MapFactory.CreateMap(String name, MapType mapType, MapViewingMode defaultViewingMode, Basemap basemap)
Unfortunately I have no idea what my error is.
Thank you, for reading
Andreas Ruloffs
