Overview
ArcObjects components are the building blocks of ArcGIS software. To support or automate organizational workflow tasks, ArcObjects can be used to extend core ArcGIS functionality and create custom applications. This course provides a foundation for application development using Visual Basic for Applications (VBA) and ArcObjects. In course exercises, students create usable ArcObjects code for typical GIS programming tasks. Students work with VBA development tools and the ArcGIS Customize dialog box and learn how to access online help resources. After completing the course, students will have a variety of sample code from which they can build their own applications.
