You may already have Process Explorer (from Sysinternals, now part of Microsoft) installed. If not, go ahead and install it now -- it's just that cool.

In Process Explorer: locate the process in question, right-click and select the TCP/IP tab. It will even show you, for each socket, a stack trace representing the code that opened that socket.

On Vista, you do need elevated privileges to use the -b option with netstat. To get around that, you could run "netstat -ano" which will show all open ports along with the associated process id. You could then use tasklist to lookup which process has the corresponding id.

<pre><code>C:\&gt;netstat -ano

blocks|key|1537383|text|Windows+8(可能还有7%2B+Vista)也在资源监视器中提供了一个视图。如果您选择网络选项卡，则有一个名为“侦听端口”的部分。可以按端口号排序，并查看哪个进程正在使用它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1537384|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Windows 8 (and likely 7 + Vista) also provide a view in Resource Monitor. If you select the Network tab, there's a section called 'Listening Ports'. Can sort by port number, and see which process is using it.

I want to be able to figure out what port a particular program is using. Are there any programs available online or that come with windows that will tell me which processes are using which ports on my computer?

PS - before you downmod this for not being a programming question, I'm looking for the program to test some networking code.

What port is a given program using?

我希望能够找出某个特定程序正在使用的端口。有没有在线提供的程序或windows附带的程序可以告诉我哪些进程正在使用我计算机的哪些端口？在你降级这不是一个编程问题之前，我正在寻找这个程序来测试一些网络代码。
