if i initialize Args with this line it works:
RENDERARGS Args={VSync_Undefined,0,0,0,0,0,0};

also a little test works:
tagVSYNC test=VSync_Undefined;
tagVSYNC test2=(tagVSYNC)0;

can i get this line to work with some trick?
tagVSYNC test=0;

thx 4 help so far !

Have you considered something like:

typedef struct tagRENDERARGS
{
    VSYNC Status;
    HWND hWnd;
    HDC hDC;
    BYTE nBPP;
    BYTE nRefresh;
    bool bFullscreen;
    bool bZoomed;
 
    tagRENDERARGS()
    {
        Status = VSync_Default;
        hWnd = 0;
        hDC = 0;
        nBPP = 0;
        nRefresh = 0;
        bFullscreen = 0;
        bZoomed = 0;
    }
 
} RENDERARGS, *PRENDERARGS;
...
RENDERARGS Args;

Hello everyone,

Any tool could be used to detect which process or module (e.g. DLL) is occupying a specific TCP port?

When I write code to bind to a specific port, there is always error says the port is occupied. I typed netstat but the port is never showed. Do I need some special parameter to netstat?

thanks in advance,
George

Hi AnShUmAn,

Using telnet, you can check whether a port is occupied, but you can never know which process occupied the port. Any comments?

regards,
George

I think we have a counter for it(Im not sure).

Hi Hamid,

I do not know how to use counter to monitor the port and which process is using the port. Could you more description about your idea please?

regards,
George

You can use of PdhAddCounter for insert and monitor tcp/ip.

Hi Hamid!

I think you can use TCPViewer, it is very powerful. Smile | :)

Yes, Hamid! It needs manually develop some code, and now a quick usable tool is better for me. Smile | :)

Use netstat.

This command lists out all opened TCP ports along with the exe's name

netstat -p TCP /b

Cool Nibu, I can find the port is occupied, but the PID column is displayed as [System], what does it mean?

(BTW: for other items, the exact exe name which is using some port is displayed.)

George

That's the kernel process ntkrnlpa.exe whose process id is 4. "They" call it System.

Great man, Nibu!

Does it mean the kernel is using that port?

Use TcpView[^] from Mark Russinovich.
It's excellent.

You can also find detailed information using the ProcessExplorer[^] regarding loaded dlls and such by double-clicking on a process.

Hi Roger,

I like TCPView, but does ProcessExplorer have this function to monitor port usage?

George

Nope, not in the same way. But you can monitor the connections on the TCP/IP tab in the properties dialogue for a process.
You can also get a lot of information about the process and what dll's is has loaded.

You mean Process Explorer provides process basis view other than global port view?

Don't know what you mean.
I meant for you to use TcpView in order to figure out what process has opened which port and then use ProcessExplorer to get more info about the process and its loaded dll's.

Try ProcessExplorer. If you find it useful simply continue to use it, otherwise throw it in the trash can.

Thanks Roger,

Sorry for my bad English. Let me say in question in some other words. Could you point out under which menu could we have port usage of a process under Process Explorer please? I have tried but failed to find out.

George
