Ever want to know which of your ports are being used while your on the net? Well, here is a full fledged application, you can scan ports in ranges such as 1-65530 or you can select 11 diffrent ports to scan, and you can watch 2 ports to see if incoming data is being sent on that port. good to see if someone gave you a trojan! And with the timer control, you can automate your scans and even save them to a log file!

Firewalls are used to block all communications to the specified port and you can specify different ip/tcp addresses to block completely.. (Pheew)

Is there anyway to Close the Ports?

It shouldn't be all that hard to make a firewall. Just use an arrary of mswinsocks. On winsock1_connectrequest, it should use the winsock.sendata command to send a message to whomever is trying to connect that the port is being blocked. Next, it should close the connection and reset itself using winsock1.close, then winsock1.listen.
On form_load, the winsock1.localport should be set to whatever port needs to be blocked. Try using a for / next loop to access all elements of the arrary. If i ever get around to making one, i'll post it.

This is code for if you want to make a firewall. In your firewall app, you should pop up a message box saying if you want to reject/accept a connection on a port. This is exactly like a firewall if you do this.

Hmm, not bad, but you should've used winsock cloning to extend the 11 max ports to scan... That way you could've increased the amount.
Can I also recommend that you change 65530 to 65536, I'm pretty sure that there are that many ports... You'll have to check. Anyway, nice work!
