Port Checker, checking IP and port

Recommended Posts

cdtoews

## Updated 6-19-08 ##

I made a small program to monitor an IP on a certain port.

I have to monitor IP's, but do not have ICMP available. So I have to monitor if I can get there on a certain port.

I tried to use the built-in tcpconnect, but found odd results. I finally went with scripting against Microsoft's portqry.exe (never re-invent the wheel)

It's downloadable from:

http://www.microsoft.com/downloads/details...;displaylang=en

Here is my code:

#cs
v2.0 got the status gui working,
v2.1 going to try to get an exit button working
v2.3 fixing tooltraytip
v2.4 ip in window name
v2.5 stripping white space
2.7 adding ID text, and reconfigure
v2.8 trying to change infrastructure so exit and setup work immediately
        removed exit button, as this mode of gui doesn't need it
