I need help writing this program
development of the software displays the topology of network based routing.
I can not later add, bust network route using a socket.
The program must identify all computers connected to the network no matter the topology.
help me please

You're pretty funny. At first I don't know what is aim of project. And nobody have complete code of your future application. Ask specific question.

What it sounds like you're saying and typical of so many who visit here, you want someone to do your homework for you. Generally, all you're going to get is grief over it.
Once you agree to clans, tribes, governments...you've opted for socialism. The rest is just details.

Help yourself: start writing the application and ask for specific help.

First of all great subject line.

Okay, so what have you tried to do?

Huh? That makes no sense at all. I don't know that I would want to help someone that want's to bust a network with or without a socket.
edmagas wrote: The program must identify all computers connected to the network no matter the topology
So you just need to enumerate network resources?
Why is common sense not common?

Detecting the "bust network route with a socket" is like "making a car with a screwdriver".
Before seeking a source, learn about the "mechanics": what about routing, how to get routing tables from routers etc.
Otherwise you will get lost in the see of "screws".

The client server application, is a simple purchase order application
I wish to write each order received by the server sequentially to a file.
What would be best practise?
(1) Keep the file open whilst the program is running, then write each order received during the server session, then close the file when the program ends.
(2) Open then write the record then close the file for each order received
What would be the pros and cons for the above mentioned?
Thanks in advance Simon

Which one is more attractive? Well, number 2 is more flexible in case someone else has to edit/archive orders... unless you are running into performance problems, which would make number 1 the more attractive contender in this battle of designs.

No. 1 is better in terms of performance.
You could give it read share access if any other program wishes to read the same file when it is kept open.

I always prefer (2) one, because if there is any crash, chances of data-loss is very much.
Secondly it also depend how frequently is data coming, if it quite fast, then option 1 also stands good.

As the others have mentioned keeping the file open will be faster but second will be more secure if something goes wrong.
You might be able to get some of the the performance of keeping the file open with opening and closing it every time by opening the file unbuffered. This[^] has got loads of useful info about the pain in the neck this is to sector align buffers if you're on windows. You can do something similar on Linux with the open() system call.
It all depends on how much money's involved if something goes wrong and how much the customer is willing to pay for security. Another solution might be to open and close the file every transaction and make sure the powers that be spend the money they'd have spent on you engineering a software solution on more memory for the server to reduce the impact of repeated opens and closes.
Another option might be to try the double open trick that used to work years ago on some Unixen and DOS. You'll have to see if this does any good, I've not used it on any version of windows since Windows '95. What you do is open the file when the program starts. This makes a second opening really quick when you write a transaction. when you finish writing the transaction you close the file which flushes it to disk. Finally when the program terminates you close the original opening.
Cheers,
Ash

Ive successfully injected my .dll file, using the native API NtCreateThreadEx(), into the system process, such as lsass.exe. But its strange that my codes in the .dll file just dont work. However, if I inject it into user processes, such as explorer.exe, that .dll file can work perfectly. So I just cannot get around this prob. Can anyone help? Thanx in advance!
My developing environment is: VC2008 and Vista.

Just imagine if it was easy to do what you want to do.
Now, I realise that you are a Saint who spends all winter bringing the homeless blankets and dinner, a regular Nobel peace prize winner [*], but I have an uncomfortable truth to give you...
Not all computer people are as nice as you. Some of them are even bad people. And not just CPallini either!

You are correct. It really is a classic song! Full of perky jealousy!

Now that's the type of message I would rate a 5.
Not due to the geographical insinuations.
Nor the musical references.
I don't really know, but it just appeals to me.
