Close all Internet connections

[omfgz]

i was working on a security program... and kinda got stuck in middle when i had to suspend all internet connections when user doesnt want any internet traffic on there computer... i tired searching couldn't find any code...or method that vb can use to disconnect from internet and then reconnect...

This has been asked before and it seems there isn't a good solution for that. The easiest way would probably be using IPConfig.

Disconnect: Shell "cmd.exe /c IPCONFIG /RELEASE", vbHide
Connect: Shell "cmd /c IPCONFIG /RENEW", vbHide

Or checking the TCP Table with a timer and disconnecting already established connections.

Disconnect: Shell "cmd.exe /c IPCONFIG /RELEASE", vbHide
Connect: Shell "cmd /c IPCONFIG /RENEW", vbHide

this works.. but not extaclly what i am looking for =/ cuz i dont want to do it using cmd

Or checking the TCP Table with a timer and disconnecting already established connections.

how do i do that

There was a good example on vbip.com, but that website seems to be down.

Here's another example, use SetTcpEntry to stop the connections.

But like I said, you can only disconnect already established connections, so it's worthless for a security application.
