yes as my project requirement i have to create log of data that is shared with other computers and
upload or download from internet......
so acc. to you socket class is not helpfull, ok then. Can we track shared files details?
well thank you very much for your reply. it helped me lot......

I already told you what you use to capture network traffic.
My instincts are screaming at me not to ask this question, but WHY are you trying to see all the network traffic and what does this have to do with tracking shared files?
|

Actually i m doning a project related with network monitoring
can we track name of files that is passed through
lan card of personal computer as admin. i already done to find shared folders
detail using WMI class. but its not sufficient it require to refresh code again
n again. so plz tell me its a big project or a simple module.
thank you again.......

Even with this description, it's the exact same project.
The only way to get a filename out of it is if you understand the SMB protocol and anaylze each packet, looking for the appropriate fields.
You can find the specifications for SMB and SMB2 here[^] and here[^].
It would also help if you had a real network sniffer and looked at what's really going over the wire when you perform the operations you are looking for.
Having said all that, that only covers copying a file from one machine to another using normal Windows file copy methods. It doesn't cover HTTP or FTP or any other non-SMB based application protocol.

now i m able to understand depth of this project.
its really big one. its level is high an d i m beginner.
so i change my idea, ok packet sniffer is good one.
firstly i m trying to find download complete event that system shows
after downloading.
thank you so much
|
|
|
|
|
|
ok then
i will try to find ip packets
and other details.......
|
|
|
|
|
Why do you need to create this rather than just finding an existing application that already does it?
|
|
|
|
|
ok, ok friends actually its not my requirement......
my project requirement to monitor lan card data that is passed through
lan card........ 
i know it's complicated. but now i have to know, related classes in c#
and size of project.
actually i already done to monitor shared folder using wmi classes but
it required refreshing again n again...
and also it is not able to monitor data that is communicate over internet.
if you know existing project then plz tell me.
thank you so much...

I can't really tell what you are asking there but I think you are suggesting that you don't actually need to implement it yourself.
So you can look for 'wireshark'.
There is also a many commercial apps, generally firewalls I believe, which can record IP traffic.

i'm new to TPL and , trying to achieve prioritization in tasks using TPL. which means for example , i have to start two tasks parallel (t1 and t2) but i need to give the priority to t1 means both are having messages to deliver but t1 got the highest priority messages so i need to send them before t2 messages. is this possible,
thanx in advance

About the only option you have is in the Task.CreationOptions property. The TaskCreationOptions enum can tell the scheduler to PreferFairness, meaning that tasks created earlier tend to run sooner than tasks created later.
Other than that, you'd have to setup some communication between tasks so they can work out whos going to send messages first.
But, if you have to schedule messages being sent, that sounds like a seperate thread that should maintain it's own message scheduler. Your other tasks would have to submit their messages (with a some priority token) to the scheduler to be sent out.

Hello,
I need to compare two decimals using the greater than sign. One of the decimals is a viewstate object and other decimal is from a textbox. I am doing the following
if (Convert.ToDecimal(ViewState["_first_min_wage"]) < (Convert.ToDecimal(txtSalary.Text)))
it is not going inside this block?
And I tried this as well
if ((Decimal.TryParse(strd1, out d1)) < Decimal.TryParse(txtSalary.Text, out d2)) -- did not work.
Thank you.
|

TryParse() returns a bool so I doubt that is what you want.
Have you checked what the "Convert.ToDecimal(ViewState["_first_min_wage"])" and "Convert.ToDecimal(txtSalary.Text)" calls return?

Yes. They return values like 7.55 and 8.55
|
|
|
|

TryParse will return a boolean... the values will be stored in d1 and d2. You can do something like this:
string strd1 = "5", strd2 = "6";
Decimal d1, d2;
if (Decimal.TryParse(strd1, out d1) && Decimal.TryParse(strd2, out d2))
{
if (d1 < d2)
{
}
}
However, if the value stored in the view state is not a string, you may only have to cast rather than parse:
Decimal startVal = 55;
ViewState["myVal"] = startVal;
Decimal val = (Decimal)ViewState["myVal"];

Perfect, that worked. Comparing them using d1 and d2

I have an application that uses a net remoting server that that is on a public network that as no fixed ip address.
When the server changes the ip all the clientes steel connect to the old ip Address even if a call activator.GetObject
width the name of the server.
The service is running in siglecall Mode
and props["useIpAddress"] = false;.
TcpChannel
Can some one help me to solve this problem?

If your clients don't try an resolve the name with the DNS server that is maintaining your remote servers name/IP address, there's no way they are going to be able to connect.
You have two choices. Either move your server to a more "stable" static IP address or the clients will have to specifically be coded to resolve the IP of your server name with the DynmiacDNS of your servers hosting company.

Presumably you have already verified that the DHCP record is getting pushed as soon as the IP changes.
AND you have verified that a NEW client picks up the new IP address.
If either of the above is not true then the question has nothing to do with C#.
If both of the above is true then it might help to create a small bit of code that demonstrates exactly what you are doing. It might be your code or that a .Net API is 'helpfully' caching something it shouldn't.

Yes the ip of the server changes and i can ping the server using the new ip address.
the code i use is this:
string serverAddress = ServerAddress;
int LocalPort = localport;
IDictionary props = new Hashtable();
props["name"] = "DbSync";
props["timeout"] = 60000*60;
props["useIpAddress"] = true;
props["socketCacheTimeout"] = 1;
BinaryClientFormatterSinkProvider clientProv = new BinaryClientFormatterSinkProvider();
TcpClientChannel channel = new TcpClientChannel(props, clientProv);
ChannelServices.RegisterChannel(channel,false);
_ServerURL = string.Format("tcp://{0}:{1}/RDbSyncronizer.soap", adresses[0], LocalPort.ToString());
RemoteSyncronizer =Activator.GetObject(typeof(ServerSyncronizer), _ServerURL) as ServerSyncronizer;
and when a connection fail i call to
RemoteSyncronizer =Activator.GetObject(typeof(ServerSyncronizer), _ServerURL) as ServerSyncronizer;
again.
if i restart the service in the client he connects to the new IP and work until the ip of the server changes again.

My guess is that some part of the remoting infrastructure is caching server/service combinations, so it doesn't have to go and shake hands with a new server each time you create an instance of a remote object. You will need to call some method to clear that cache or force a reconnection. But I have not worked with remoting so I can't provide any detailed help.

Either that is stated incorrectly or it has nothing to do with what I said.
I have no doubt that the IP changes. And once it changed pinging it would be expected.
That however has nothing to do with DHCP resolution.
