Help with what? you have not explained what the problem is. I suggest you add some diagnostic code to your program or use the debugger to step through and check what is happening.

1 solution

your send function looks strange. Does it work?

I would write it a little better
C++
send(connected, "100",strlen("100"),0);

normally is such code written in that way
C++
 int cnt = 100;//or some dynamic value
 char *buffer = new char[cnt];
memcpy( buffer, someSourceData, dataSize );//smaller than cnt
send(connected, buffer,dataSize,0);
