Question regarding Using directives

JimMeuse — Thu, 25 Apr 2013 13:08:02 GMT

Getting started in ArcObjects 10.1 SDK...

Within Visual Studio 2010, I entered in the following for Using directives:
using ESRI.ArcGIS.ArcMapUI;
using ESRI.ArcGIS.Desktop;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Framework;

I tried creating an IMaps variable by entering:
IMaps pMaps = pMxDocument.Maps;

But I am getting an error "The type or namespace name 'IMaps' could not be found (are you missing a using directive or an assembly reference?)". Based on Intellisense, I don't see what other directives I should use. This seems like it should have an obvious answer which I am missing.

IMaps is in the Carto library. You don't have a Using statement for Carto.

Thanks, Neil. What do I need to do in order to get rid of the error?

Add the Using statement.

I'm sorry, I must appear appallingly slow...but what exactly do I need to type in my code?

Re: Question regarding Using directives

using ESRI.ArcGIS.Carto;

Thanks again, Neil.

When I first typed in using ESRI.ArcGIS.Carto, I got the following error message: The type or namespace 'Carto' does not exist in the namespace 'ESRI.ArcGIS'. Then within the Solution Explorer I right-clicked References >> Add Reference... and in the .NET tab I selected ESRI.ArcGIS.Carto. Then no more error messages.

There are quite a few ESRI references in the list of references under .NET. Is there some source which shows which specific references are required for specific interfaces which a user wants to use?

The topic for each interface/class in the developer help shows the library it is in.

Thanks, I'll look that over.
