Programming the COM+ Catalog is nothing more than understanding the Catalog programming model and navigating down the Catalog structure, using the Component Services Explorer or the Catalog structure diagrams in this chapter as reference guide. This chapter focused on the Catalog structure, not on the semantics of the items it contains. Although the Catalog interfaces were designed for scripting languages, you can access them from C++ as well, and the resulting code is just as concise. Some COM+ services features are available only by accessing the Catalog programmatically (in particular, some features of COM+ Events, discussed in Chapter 9), so knowing how to work with the Catalog is an essential skill. Furthermore, automating mundane and repetitive development and deployment tasks by programming directly against the COM+ Catalog is fairly easy.
