Network Interface Debugger

Simulate Serial debugger, in order to facilitate network debugging, which friends like e-mail: songkun607@yahoo.com.cn, the main function is to connect to the client connection, send and receive data, you can automatically obtain the local IP address, it can be displayed in ASCII or hexadecimal format. The following is a service class I wrote, mainly for SDK programming ///// wsaserver. h ///////////////// # include <winsock2.h> # include <windows. h> # pragma comment (Lib, "ws2_32.lib") # define wm_socket wm_user + 1 class wsaserver {public: wsaserver ();~ Wsaserver (); int setserver (hwnd, char * IP, int port); int wsaaccept (hwnd); int wsarecv (socket clientfrm, char * buff, int Len ); int wsasend (char * buff); int setclient (socket clientfrm); int getlocalip (char far * Name, char far * IP); Private:/* wsaasyncselect handle, parameter settings */wsadata WSA; socket m_server, m_client; sockaddr_in serveraddr, clientaddr ;}; /// // wsaserver.
