Just from the look of it, it's VB..ehh; why reinvent the wheel if you don't make it better; there are already much better alternatives, for example nmap is a much more robust port scanner than the one provided here. I congratulate you for your effort, lol.

The biggest benefit is that it's all together, I like the portability of programs. But I do have to agree also. That, and some other other tools can be expanded on or made into something different. Like an invisible bot server.
