If I create a public struct containing the exact same fields and set each field to something, can I pass that public struct as a parameter to the mutator method to set the private data members to? Does this fall under poor coding practices category or is it an exception to the rule? Thanks! Is User Active ?

Antony M Kancidrowski12-Aug-04 7:48 Antony M Kancidrowski 12-Aug-04 7:48  Take a look at NetUserGetInfo() using level 1. The USER_INFO_1 structure has a field called usri1_flags.

Excel Rassul Yunussov10-Aug-04 19:27 Rassul Yunussov 10-Aug-04 19:27  Hello Everyone, i got one question about how to get data from excel files. I know the one way - to query to it using ADO. But if the table doesn't have a name - i can't get data from it.I just want to access to excel tabular data as to array.

This Network monitor will capture packets, display them, find number of packets transmitted by system per second etc. Now question is how I'll scan network using 'IP Address' because I think Winpcap is useful only if you knew MAC address. While I have to develop such software which on getting IP Address, analyze all network data that is transmitted by that computer. I'll highly appreciate if anyone comes up with any good suggestion. Thanks. A Khan Re: Network applcation in C++ 4apai10-Aug-04 22:35 4apai 10-Aug-04 22:35  try WNet functions Re: Network applcation in C++ A Khan11-Aug-04 1:35 A Khan 11-Aug-04 1:35  Thanks for reply. But please elaborate how do you think Wnet functions will help. I have gone through MSDN, other resources and my understanding is; We CANNOT retrieve MAC address if we have IP address of any machine in network.... if this conclusion is wrong, then please do identify how can I do the same. Thanks again. Re: Network applcation in C++ 4apai11-Aug-04 3:27 4apai 11-Aug-04 3:27  i just misunderstand u. i think u need to enumarate network resources: IP, etc. hm. how to get MAC from ip. what about network utilities, smth like nbtstat... Re: Network applcation in C++ Antony M Kancidrowski10-Aug-04 23:52 Antony M Kancidrowski 10-Aug-04 23:52  The problem you will have here is seeing the network traffic from the other computer. If the machines are switched to the desktop you will not see the traffic from the other machine unless it is intended for you. The only sure fire way to see the traffic is to run the capture on the machine in question. I believe that WinPcap does have a remote agent capability, or at least they are planning on adding this capability. Ant. I'm hard, yet soft. I'm coloured, yet clear. I'm fruity and sweet.

I have to show this thing to my boss soon and I just cant figure it out, how I will be able to do this. Do you have any more suggestions, I will be highly appreciative. Re: Network applcation in C++ Antony M Kancidrowski11-Aug-04 2:50 Antony M Kancidrowski 11-Aug-04 2:50  WinPcap works by binding to a NIC in promiscuous mode. This allows the driver to see all packets that the NIC sees i.e. all packets that your computer sees. In order to see all packets that another computer sees you need to run WinPcap on that machine (at least in a remote agent capacity). It isn't sufficient just to expect your machine to see the packets from the other machine. (See previous reply with regards to switched networks). If it is proof of concept that you need to show your boss it can be done for the local NIC. The principles are the same for local and remote. Writing network monitoring applications takes time and understanding of networks. Generally they are not something that can be written in a couple of days (though drivers like WinPcap help speed up development vastly). You may want to look at the RFC's for IP (RFC 791)[^], TCP (RFC 793)[^] and UDP (RFC 768)[^]. This will give you some understanding of the structure of IP packets. Ant. I'm hard, yet soft.

I have understanding of these RFCs and protocol headers but I just cant find way to get packets being recieved by other computer, of which I only knew MAC address. Okay Winpcap is something that is making it impossible for my appplication to do the same... So do you have any idea of some other library that can give me the functionlity I am looking for.

Sorry, on this occasion I can not help. All network monitoring software packages that I am aware of work with a remote client agent on the machines in which they want to monitor. This way they get around switch blindness. Good look in finding a solution that suits you. Ant. I'm hard, yet soft. I'm coloured, yet clear. I'm fruity and sweet. I'm jelly, what am I?
