So far I have been able to use it on XP and Win7, and run the programs on Win8. I hate the new versions of Visual Studio as it seems they went out of their way to break it and make it as slow as possible. Don't know exactly why they had to screw it up so bad when they went to .net, but VB in that environment is a totally different animal, and much slower to develop with.
Just today I was writing a couple of small programs, one on the survaillence computer at our transmitter, and one here at master control (tv station) to let the operator know when one of the cameras sees something. A total of less than 30 lines of code. Runs the program with the camera name on the command line and passes the that to a computer at the station which logs the event. Tomorrow I have to work on having it ring a bell...
