  11. Software support resources • Online Support Center isgateway to resources http://support.esri.com • Downloads • Software upgrades • Technical papers • ArcScripts • User-to-user resources • Discussion forums • Email lists • Technical archives • Knowledge base • Documentation • System requirements • ESRI Technical Support • Request support online • Find phone and fax numbers • Available to support subscribers

  12. ArcObjects: The foundation • Development platform for all ArcGIS applications • Three main products: ArcInfo, ArcEditor, and ArcView • Applications: ArcMap, ArcCatalog, ArcToolbox, ArcScene • Application extensions: 3D Analyst, ArcPress… • Available license controls the objects that are available • No reinstall required • Developers use ArcObjects to write custom COM objects to extend and customize applications

  13. Development triangle Embedding ArcObjects Stand-alone applications Custom features and workspaces Custom layers and renderers Document persistence Windows Property pagesViews Geodatabase class extensions Application extensions Editor tools Commands Buttons Tools Menus Toolbars VBA Macros and UIControls 2 Map Control Difficulty of implementation Recommended progression ArcObjects Framework 1 Start here

  14. ArcObjects development with VBA • Learning ArcObjects: Many samples, help system • Prototyping, testing, and exploring ArcObjects API • For relatively simple application extensions • Distribute functionality in an MXD or MXT format • Free

  15. ArcObjects development with VB • Everything possible in VBA • Implement interfaces and create custom components • Obtain more advanced functionality and extensions • Encapsulates COM programming details • Very easy to use and fast to write prototypes • Many samples • Hide code in binary DLLs

  16. ArcObjects development with VC++ • Everything possible in VB and VBA • More advanced components and extensions options • Implement every interface, even those supporting inheritance • Other considerations • Rich Object Oriented development environment (inheritance) • Better debugging environment (no problems like VB 6) • Control type library names and GUIDs explicitly • Explicit control of COM server design (e.g., custom marshaling) • Considered standard for large-scaled software development projects

  17. Which development environment to use? • Reasons you should avoid using VB • Advanced component implementation or interface inheritance • Interface members contain IUnknown* argument types • Application requires aggregation • VB hides implementation details: Is that really bad? • Performance concerns? • VC++: Fastest • VB: Approximately 2% slower • VBA: Approximately 4% slower • VB versus VC++ development time? • Depends on experience level

  18. Exercise 1 overview • Install the class data • Determine the installation directory for ArcMap • Explore the class materials: Data, exercises… • Set Visual Studio file paths for: • esriCore.olb • ArcCATIDs.h

  19. Review • What is ArcObjects? • What are three main ArcGIS products? • What are the two main levels of customization? • What is the best development language to use? • What is the most important developer resource? • What is the purpose of IExtensionConfig?
