hai all masters,
here is my problem.
i want to access a hardware device(server) through TCPIP.
i know its ip address, and i want to write an application(client) to access it. but i donot know the port number.
is there any way to access it with out knowing the port number?
if any more clarity is required, then i can provide.
please give your views on this.
thanks in advance.

Of course:
(1) choose randomly a port
(2) are you able to communicate with the device?
(3) if the answer is yes then you're a lucky guy.
(4) if the answer is no, goto point 1.
That's called Montecarlo TCP/IP.

thanks pallini,
of course i have tried that before posting it here. i tried from 0 to 10000. but no use
any way let me provide you more details such that, you can help me.
1.the device is access control system(card swipe system) in our office.
2.the vendor has provided his software, which will download the swpe logs to the PC.
3.for some reasons, i wanted to have my own software for that.
so, i did the following things.
1.i made a session in hyperterminal using tcpip with the device ip and default port number 23.
2.then the device responded with welcome note, version number and a login prompt at my hyperterminal.
3.so here, i under stood that, i have to provide some username and pwd.
so i tried to simulate the server(the device) through my application and communicate with his software and find the username and pwd.
but the application is unable to communicate with my simulator.
any ideas on this?
please excuse me members, if my post is a bit lengthy.

I was just kidding, of course. Why don't you issue the netstat command (from command prompt) while the device is connected with vendor software to see involved ports?

wov thats wonderful. i was exactly looking for such a tool.
but it gives me the results all at a time. not in real time.
i mean, if i start it, and then start his application from another system, then it(netstat) should show me the commands that got transfered from one port to other.
any way, i shall look into the options of it and get back to you.
or if you have any idea of such an application then please forward me its url.
thanks for the clue.

but how come did the device respond to my hyperterminal with port number 23?
any idea on this?
and more over, with other numbers it is not responding.

It accepts telnet connections. However maybe the vendor software uses another port to communicate.
Why don't you ask the vendor?

yes i tried that even,
but he said it is not possible so easily.
and he want to take his own time to give me the techical details.
but iam not sure about him.

netstat could not give me the exact information that iam looking for.
can you suggest me any other idea to achieve my goal?
thank you.

Nope. Try the Hardware / Device Drivers [^] forum.

Owner-draw or standard menu?
System menu or user-tracked pop-up menu?
If it's owner draw, have you checked to see that you're calling ReleaseCapture to give the mouse back to the rest of the system?
Also, check your code surrounding any OnMouseLeave events or OnMouseOutOfWindowForTooLong timer events.

You should not use the "append" mode while opening the file. Now, I can't give more detailed explanations because you didn't provide the code to open the file...

This is not the way to do it. Are you storing some information related to your program? In that case, have a look at WritePrivateProfileString[^] and GetPrivateProfileString[^]
(You have options to write and read Int as well. Just look at related methods.)

And please avoid deleting messages. It makes the entire thread useless. Nobody will beat you down for asking a question like that. You just did not know how to do it and that is not a problem at all.

If that's your homework then someone is pulling your leg ( having a joke wiht you )
You probably need to research the 'completion problem' to understand what you're up again. If you're a math oriented person then equip yourself with a good understanding of 'Turing's theory of computability' to explain to whoever told you to do this why it isn't a good idea.
