Introduction to Programming ArcObjects using VBA-x
ArcObjects components are the building blocks of the ArcGIS family of products, and the ArcObjects libraries provide a rich set of functionality that developers can use to build powerful GIS applications. This course introduces the ArcObjects libraries to Visual Basic for Applications (VBA) programmers and teaches how to develop custom applications and solutions that extend core ArcGIS functionality. Students work with VBA development tools and the ArcGIS Customise dialog box and learn how to use the various help resources available. In course exercises, students work with the ArcObjects VBA developer resources to create applications and tools that perform specific GIS tasks including map navigation, feature selection and rendering, spatial operations, data projection, data management, editing, geoprocessing, and map creation.
