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

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

1-19


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

1-20


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

1-21


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
