1. Thank you for admitting this is a homework question. When people try and hide this we can get irate.
2. Although we would like to help you, its better if you present what you have managed to do so far and where you have got stuck. Being presented with a complete answer circumvents the learning process which we here at CP would like to encourage. There is no better way of learning than getting your feet wet. Once you have paddled around for a while, we will be happy to help you out in deeper waters.

thank you

At first, I would try to find out what kind of objects you actually going to need, and how they are interconnected.
For this you could use UML, but I think this is way too complicated in you case:
Just scribble away from the bottom of your heart, and after a few/lot of/nearly unlimited number of iterations things will get clearer.
You will have at least some idea about how to start the task - Which is what you seem to lack by now.

i didn't quitely understand what do you mean what kind of objects i am using, but i can tell you that i have to use RTC

Whan I meant was that you did sound as if you need to get a start into your project.
For me, the best way is to draw some sort (all sorts) of diagram to start to get the hang about where to start.

no, RTC (Remote procedure Call)
attached the initial document ( design ) with the client and server attached. I am still stuck with the posting of the message with the error: rpc cannot enable arguments
question: how can i attach files to you

Now this the first time you ask a precise question. People here are glad to help you out when you ask this kind of questions, but do hate the 'Please do my homework!' style. (As Roger Allen already mentioned)
As for the code: you can simply enter it into the textbox and wrap it in <pre> and </pre>.
For the picture, it might be OK to post a link to a webserver where you have placed it.

This is some linux/gcc -c code.
I have no idea how this is working and I can't test it. And, btw. I won't do your homework!
You need to ask specific questions, preferably in another thread, and with a meanigful headline. This way, all people who (unlike me) know about your subject feel invited to help you.
I hope I could help you at least a little.

The first procedure is used to login as a user
The second is to connect to a server.
The third procedure is to view list of available messages.
The fourth procedure is for posting messages.
The fifth procedure is for deleting messages read or unread.
The sixth procedure is for reading messages.
The seventh procedure is to start the server.
The eighth procedure is to handle the expiration of messages.
The ninth procedure is to handle crashing server.
The tenth procedure is to handle crashing client.
4. Running the program
To start the server application, enter: mserver
To start a client application, enter: mrn [hostname]

Get a copy of the directshow SDK. I think that it is now part of the main DirectX SDK. Have a look at the AMCap sample application, should get you started.

Hi,
I'm having problems with the CMenu class and was hoping someone would be able to help. The problem is that the CMenu class is modal and therefore stops the rest of my application from running whenever a menu is opened. This is a problem because every program cycle I look at a comm port and read in whatever is in the port. If someone leaves the menu open the buffer fills up and I have to resynchronise with the external hardware. Is there a way to make the CMenu class act in a non-modal way or is there a way to handle the comm port (without using threads preferably)?
I'm using Visual Studio 6.0 and am using the MSComm ActiveX control to communicate with the comm port.
Thanks in advance,
Phil

The problem here is not the CMenu class. You have a classic problem of trying to do too much in the UI thread. You should be spawning a worker thread to deal with the communication port sending/receiving. This other thread can post events to the UI thread as they occur in the form of message, which will be processed in the UI thread even if a menu is open.
I do beleive that the serial port example(s) here at CP take this approach.

I was worried you'd say that... I think you're right. I've used the UI thread in the past for processing comms but never with the CMenu class as well. Never mind, rework here I come.
Thanks for the help.

You didn't say for what protocol, but if you are talking about HTTP, try looking at HKEY_CLASSES_ROOT\http\shell\open\command.
