VBA help please Options

[aimpul]

I am new with using Z-Wave and have limited VBA experience. I am needing to remote control a light connected to a switch which is connected using Z-Wave from ControlThink v.2.4.5. I need to use VBA 6.5 code from another software application to connect through the ControlThink software to turn on/off the light. I don't know where to start, except, that reading many forums and help sites, it says to use the ControlThink.ZWave.dll to accomplish this. I have been unable to locate code samples as to how to do this. I am unable to add the .dll as a reference using the Tools/References menu in the Visual Basic Editor. Reading up in the VB hjelp files shows me how to add a .dll to a module, but I do not know what parameters to use, nor can I find any examples how to actually do anything with the functions and subroutines within this .dll and how to use them to accomplish the task at hand. If anyone can help, it would be greatly appreciated.
