What errors are you getting or what runtime problems?

--------------------Configuration: Socket - Win32 Debug-------------------- Compiling... Socket.cpp D:\Win_sock_chat_server\Socket.cpp(21) : error C2065: 'clientaddr' : undeclared identifier D:\Win_sock_chat_server\Socket.cpp(23) : error C2065: 'message' : undeclared identifier D:\Win_sock_chat_server\Socket.cpp(23) : error C2440: 'initializing' : cannot convert from 'int' to 'char *' Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast Error executing cl.exe. Socket.obj - 3 error(s), 0 warning(s) i can fix that by putting all the int and chars up in the right direction but it has a linking prblem too... i'll try to get the other error tomoroow.. hope u can help me a little

Socket.exe - 7 error(s), 3 warning(s) i fixed some more and noe i get this after compiling this: #include <map> #include <iostream.h> #include <sys\socket.h> int main(int argc, char *argv[]) { int sockfd; struct sockaddr_in myaddr; myaddr.sin_family = AF_INET; myaddr.sin_port = htons(3490); myaddr.sin_addr.s_addr=INADDR_ANY; memset(&(myaddr.sin_zero),'\0',8); bind(sockfd,(struct sockaddr *)&myaddr,sizeof(struct sockaddr)); listen(sockfd,20); int sin_size = sizeof(struct sockaddr_in); int new_fd; char buffer[250]; int clientaddr = recv(new_fd, buffer, sizeof(buffer), 0); new_fd = accept(sockfd,(struct sockaddr *)&clientaddr,&sin_size); char *msg; cin >> *msg; int len = strlen(msg); send(new_fd,msg,len,0); return 0; } tnx for any answers

i think i know what the fault is... the place where i downloaded the socket.h file said: When you compile this files, make sure you link them against Ws2_32.lib. how can i link them to that? cos it is a linking error.. i'm using visual c++ 6

For this u have to go to menu Project->Settings->Link->Object/Library modules->(Here add Ws2_32.lib) I hope this will solve ur linker problem
