The RDK ActiveX Interface (RDKX) is an ActiveX/COM wrapper for the RDK, which allows you to easily write RDK applications in an ActiveX aware environment. While Visual Basic is the environment of choice for writing RDKX applications, they can also be written in Visual C++, or any other ActiveX aware development environment. Most of the examples in this document are given in Visual Basic.
