Question
TCP/IP service trap with windows using vb.net
I need to create process using VB or VB.net that will act as a service when Windows starts that will watch for any of a number of specific TCP/IP ports being used, such as 80 that comes from a browser. Once found, the process will need to kill the calling program and then call an additional program. Is this possible? I know it is, I've seen this kind of thing before, I just don't know how to do it. Help!
