Yes..
I have implemented a Client\Server application, the communication is created through the class CSocket MFC...
The server side send to client the information to visualize...and the client side visualize it on a display..( CDialog )

When server side send information to Client an OnReceive event is performe...and thats work fine..
But same times the event OnReceive not being called...because the underlying socket system did not give any notifications...i suppose

Excuse for my bad english...

Do not use CSocket at all because it's filled with flaws. Use CAsyncSocket if any.

Read this[^] to get it right using CAsyncSocket.

Does the same thing happen with CAsyncSocket?

I have not still been able to try...
Today I will make some tests with the CAsynSocket...

Please:
1. Explain exactly what the problem is (so what exact errors do you have)
2. Format your message properly (using the pre or code tags above the emoticons)
3. Post a relevant piece of code (your code seems to be cut in the middle of a function). That also means not to paste ALL your code.

If you try to build this source code in a VC-version later than 1.52, you won't succeed, since this is a very old, 16 bit DOS program.

I would suggest you to start a new project (in a more recent version of VC++), then cut and paste the useful parts to the new project.

I am trying to open a new file using Append mode in C++. But file is not opened. If I use out mode, file is opened.But the problem is:
The data I entered once is lost during the next execution. I don't want the data to be lost. How to achieve this in C++.
Is there any specific mode in C++ for this?

You haven't said what you're using for file handling.
Are you using WIN32 handles, stdio FILE*, or STD streams?

fstream ofs("studfile.txt",ios::out);

This is the statement I'm using to open the file. If I use app in place of out, the file is not opened. But I want the contents of the files don't get erased after each execution.

Why aren't you using both?
