Using the VRS API

VRSAPI Application Programming Interface

This is a DDE like process to control VRS by finding the window and sending command messages. The file vrsapi.zip includes "readme.html" which explains more. C++ header, source files and examples are included but with a bit of knowledge the code can be used in any other language (eg. VB). To download click here...

VRSAPI is fairly simple to use. For C++ programmers just include the header and source file and call the functions. For other programmers you need to understand some basic Win32 commands like "FindWindow" and "SendMessage". VRSAPI is more suitable for applications where efficiency is more important.
