Let me explain you that one,
1.Do not start with Dialog or Doc/View conversation. First think about implementing your chat/messaging mechanism. I guess you have been coming around MFC sockets. If you ask me, I'm not for it.I did not like to work with it. You can directly use winsock2.
2. Write a simple TCP client server application in console mode. Once you find the application running and you are clear with the idea, make a simple class that takes care of simple functionalities like connecting, sending & accepting messages.
3. First try for single client-server application. When you are comfortable with it you can move to Multi-client application that would involve threading in most cases.
4. Now you are clear with Sending & receiving messages using winsock.
5. For server part, you can ultimately go for windows services implementation, but to start with I do not recommend it. Because as you are a beginner, you will have to trouble shoot a lot of things at first. So just make it a console server. Where you'll be able to view the messages going across.
6. For client, you can have it as Dialog application, but again it's just based on the need. You can even go for SDI if you want to make use of Serialize-Archive functionality of the document. It could be useful when you save down your chat conversation.
7. Did I answer you?

A sincere thanks for your reply
Got lots idea from you.Specially the steps i should follow. it sounds very professional.

what is winsock2? is it for MFC? is there any advantage on normal socket functions like listen/bind/createsocket etc (which I have worked on little bit).

lol. winsock is called - normal sockets. MFC just wraps around. You will get better understanding if you go for winsock API. I don't force you to leave MFC, but that's not my choice when it comes to sockets. Nishant Shivakumar has a neatly written TCP client server application. I'd recommend you to start with that. wait let me check it.

thnaks
could you please tell me if my design is correct.
server
->Maintains a list of Ip_Address-user. Always in listen mode, so that if someone ask for the list it sends it.
-> If the admin adds a new user, he will re-send the list to all (but I am not sure, how to do it,when if the clients are busy sending message. should i restart all or do something)
client
-> on boot/application start, it request server and get the list(His IP-username should be present in the list). And sends a message that he is online to all.
->if he goes offline- he will notify everyone and the go offline.
so basically only those people who are listed in the server by admin can only chat

Your questions are at times too open & wide.  Try with simple implementation, once you get the picture you can design your complete application.

when i m use strcat function to concatinate the two string then it gives the garbage value before the string.
i m concatinate this
//find window path-----------
char SystemDir[255];
GetSystemDirectoryA(SystemDir,sizeof(SystemDir));
MessageBox(SystemDir,"path of exe1",NULL);
char exename[20] = "\\wmvcopy.exe";
strcat(SystemDir,exename);
MessageBox(SystemDir,"path of exe3",NULL);
//clip in path---------------------
char sPath[MAX_PATH]="c:\\media\\system.wmv";
char varinput[10] = " -i ";
strcat(varinput,sPath);
//strcat(varinput,varslash);
MessageBox(varinput,"open path",NULL);
//clip save path-------------------
char varoutput[100] = " -o ";
char savePath[MAX_PATH];
strcpy(savePath, savemoviename);
strcat(varoutput,savePath);
MessageBox(varoutput,"save path",NULL);
//MessageBox(varinput,"varinput1",NULL);
//Start time------------------------
char varstart[100] = " -p ";
char tstart[25];
sprintf(tstart,"%d",posisecond);
strcat(varstart,tstart);
MessageBox(varstart,"varstart",NULL);
//end time--------------------------
//endposisecond
//duration of clip--------------------
int totalduration = endposisecond - posisecond;
char tdur[25];
char vardur[100] = " -d ";
sprintf(tdur,"%d",totalduration);
strcat(vardur,tdur);
MessageBox(vardur,"duration",NULL);
char cmdpath[MAX_PATH];
strcat(cmdpath,SystemDir);
strcat(cmdpath,varinput);
strcat(cmdpath,varoutput);
strcat(cmdpath,varstart);
strcat(cmdpath,vardur);
MessageBox(cmdpath,"cmdpath",NULL);

Of course: cmdpath contains garbage because you didn't write anything into it. So, if you try to append something to it, the garbage will be kept. Replace the first strcat by a strcpy, this way you first copy something useful in the string, then you can append things after it.

Make char cmdpath[MAX_PATH] = "";
Btw, you can have a look at PathXXX functions.

You are welcome... but I was just pointing out what is wrong. Cedric Moonen's answer is more correct...

Hi to All
I am a beginner learner in MFC.
I am confused about the topic Document View.
Why do we need document View in an application? Is it to separate the data and the view ? If so we can always have a database and a view(ie my front end application)? What can we do with document?
Could anyone please put some light on it.(May be not the whole details), so that I can have an idea and go about it.
Thanks in advance

Not all applications are database oriented  . Take for instance a simple text editor application: it makes perfect sense to have a document class (which keeps the state of only the information about the document) and a view class (which is only responsible to draw the information on the screen). That's just an example, but this can be applied to a lot of programs which are used to open file and manipulate the content (drawing applications, text applications, excell, ...)

It's something. It might take some time to understand completely. But to get an abstract view, The Doc/view's intended objective is to separate the "data" from the "viewing" code. It clearly define a boundary there. You may have any data (or the document). You can attach views to reflect(Draw/Display) the contents of data to users. You can have multiple views for the same data. It's like you are peeping through one window and another peep through another window but the document would remain same. SingleDoc-Sigle views, singleDoc-multiple views, MultipleDoc-Multiple views & also multiple types of docs & multiple views.
