How do I get the process name and binary path for a open port with Qt on Windows?

Question

I'm writing a port collision checking function. I need to determine:

• if a certain port is open
• the process name of the daemon
• path of the binary of the daemon

My idea was to run a QProcess executing the native command netstat -abno and parsing the output. But the parameter -b requires elevated rights (UAC) and i don't want to bug users with an UAC prompt.

Is there a Qt lib out there providing such functionality? How would you implement this?

Answer 1

you can use Tcpvcon.exe which is part of TCPView
TCPView Needs admin rights, tcpvcon does not
use with -an or -acn
you can even specify the application to check afterwards: e.g. Tcpvcon.exe -an Skype

Use TCPView if you want a GUI for this. It's the old Sysinternals app that Microsoft bought out
