2 Introductions Who are we? Who are you? Development D l t experience i with ith ArcObjects A Obj t Development experience with ASP.NET Basic understanding of ArcGIS Server

3 Questions? How many: y Want to migrate Desktop applications? Want to migrate Engine applications VB.NET, VB NET C# C#, C++ C++, VB6? Already have ArcGIS Server development experience?

4 Schedule Today y we will cover ArcGIS Desktop customizations How to migrate customizations to Server Best practices for migrating We will answer questions during session or at the end? Please complete the session survey!

5 Types of customizations ArcGIS Desktop p Commands, tools, toolbars, windows, extensions VB 6, VC++,.NET ArcGIS Engine Forms based and utility y applications pp Commands, Tools, extensions VB6, VC++,.NET and Java ArcObjects Components Utility y components p and DLLs

6 Migrating Desktop Applications: The Challenge 1. ArcGIS Server is a multimulti-tiered, multimulti-api system 2. ArcObjects code runs remotely on GIS Server 3. User interface is a web browser Web server Web services ((SOAP)) GIS server SOM Browser Web application SOC Server Server Object Object Desktop Web ADF (ASP.NET) ArcObjects (COM)

7 Migration options Migrate g directly y to ASP.NET Build Server Object Extension or Com Utility Object Geoprocessing ArcGIS Server WEB ADF Common datadata-source API Data--source specific API Data 5. JavaScript or Flex APIs

8 Which ArcObjects libraries can be used? Most of the Engine g libraries Capabilities Display Symbolization Analysis Query y Data Access Editing Output

9 Accessing ArcObjects remotely 1. Web app pp communicates through g ArcObjects j proxies p 2. Accesses a Server Object through the SOM 3. Works with ArcObjects in a Server Context (ArcSOC.exe) Proxies Server Object Server Context

10 Migrate ArcObjects code directly to ASP.NET Build an ASP.NET application Copy code to new Application Create ArcObjects in a server context Dim ppoint as IPoint = Net Point Dim ppoint as IPoint = servercontext.createobject( esrigeometry.point ) When Wh to t use?? Quick migration of code for testing/demo Small amounts of ArcObjects code Hint: Use Library Locator to find correct value for CreateObject

11 Steps to migrate code Build ASP.NET Web application Copy/paste your ArcObjects code Replace New with CreateObject Manage g objects j in the server context

12 Migrating ArcObjects code to a COM Utility Object Build a custom COM component p Moves code to the GIS Server (SOC) Reduces number of finefine-grained calls When to use? Lots of ArcObjects code Simplify code sharing Optimize performance

13 Steps to create a COM utility object) Create a new project ( VB 6,.NET, C++) Reference necessary libraries Define a COM Class Define a public interface or public members Migrate existing ArcObjects code Use CreateObject to create and access objects Required to register COM component on all SOC machines

14 Migrating to a Server Object Extension (SOE) Extends the capabilities p of a service Benefits Initialized once Configurable via ArcCatalog property page

15 Steps to create a Server Object Extension (SOE) Create a Class Library yp project j Implement IServerObjectExtension Optionally build a custom property page Access SOE from ASP.NET Web application

16 Compare COM Utility Object to SOE COM Utility Object Server Object Extension I iti li d when Initialized h required i db by GIS S Server I iti li d once att startup Initialized t t Created ad-hoc using the server context Registered with a specific service Configurable via a custom property page

17 Migrating Geoprocessing Service Replace p ArcObjects j code with a Geoprocessing p g Service Build a model and return results to Web application When to use? Optimize ArcObjects tasks Processes that can be modeled

18 Steps to migrate to a geoprocessing service 1. Build and test y your g geoprocessing p g model 2. Publish the model 3. Consume as a task in your ASP.NET application

19 Migration Web Application Developer Framework (ADF) Replace p ArcObjects j functionality y

21 Migrating the User Interface Web Controls Visual Studio Map template WebControls Pure ASP.NET controls AJAX enabled bl d Functionality y Visualization User interaction

22 Migrating the User Interface Commands and Tools Start with Web Mapping pp g Application pp template p Add new item to the Toolbar Specify clientclient-side action Create a new class and Implement required interface Define server server--side action Customization Interface Tool IMapServerToolAction Command IMapServerCommandAction DropDownBox IMapServerDropDownBoxAction

23 Migrating the User Interface Task Framework Tasks objects j that encapsulate business logic Out of the box tasks include: Search Attributes Find Address Editor Task Print Task Container C t i ffor displaying di l i task t k results

25 Migration The Common DataSource API ArcGIS Server supports pp multiple p data sources ArcGIS Server, ArcIMS, ArcWeb services, OGC, Graphics Common Datasource API.NET classes for the Web ADF Access and interact with all data sources the same way! Provides different functionalities - query, find, identity Common data source API

26 The Common Datasource API Web ADF controls Resource managers IGISDataSource IGISResource IGISFunctionality IMapFunctionality IMapTocFunctionality IMapResource Common data source API IScalebarFunctionality IQueryFunctionality ITileFunctionality IGeocodeResource IGeoprocessingResource IGeocodeFunctionality IGeoprocessingFunctionality Data source implementations ArcGIS Server ArcIMS

27 Using the Common Datasource API Replace p ArcObjects j code Query, Identify, Find etc Steps 1. Identify the code to replace 2. Search help to find Common API functionality 3. Reuse code to access other data sources Review SDK, code samples, OMDs..

29 Migration Data source specific APIs Composed of data sources that have functionality beyond Common data source API ArcGIS Server ArcIMS ArcWeb A W b Services S i Data source-specific source specific APIs Web ADF API Common data source API

30 Working with Data Source Specific APIs Each data source exposes a different set of functionality ArcGIS Server Web controls Web controls Web controls Resource managers SOAP, ArcObjects ArcIMS AXL ArcWeb Services SOAP API What does this mean? Resources Functionalities Data sources Many other data sourcedata sourcespecific classes available specific APIs More business/gis logic Different APIs use different communication protocols Requires different programming patterns for each data source

31 Migrating graphics Web ADF graphics data source Draws on top p of layers y in map p Used to perform tasks such as: Highlighting features Labeling Displaying buffers Geocoding g Display dynamic data Rendering occurs independently from map M redraw Map d is i nott required i d

33 Additional APIs JavaScript and Flex Take advantage of the mapping, geoprocessing and geocding capabilities of ArcGIS Server services JavaScript API Lightweight High performance Browser based GIS applications Mashups Extensions for Google Maps and Virtual Earth ArcGIS Server Flex API Build applications with intuitive, visually y rich user interface Create mashups ArcGIS API for Microsoft Silverlight
