Examples
Throughout this guide, Visual Basic code examples are used to illustrate concepts. To
make the examples more easily understood, they have been simplified. Error checking
has been removed, and in some cases, the examples are only fragments that will not
compile.
For complete examples, see the example applications provided with the LNS Application
Developer’s Kit. This includes example network management, monitor and control, plug-
in and director, and xDriver applications. Appendix C of this document describes the
example applications in more detail.
