I had developed the client program under Visual C++ 6.0. I use the Windows socket programming. I compile and build my program using the Win32 Console application.There is no errors and warnings. But after I executing the program, I found that if(argc < 3) {
printf("usage: %s <server> <data1> <data2> ... <datan>\n",argv[0]);
exit(1);
}

the output is usage: %s <server> <data1> <data2> ... <datan> and stop with executing the rest of the program.My work is to send data to the server PC which is under the Linux environment.

The following is my program:Thanks for helping.

#include <stdio.h>
#include <winsock2.h>
#include <windows.h>
#define SERVER_PORT 1500
#define MAX_MSG 100

//int CreatFile(char *szServer, short nPort);

//*CreatFile();

int main (int argc, char *argv[]) {


WORD wVersionRequested = MAKEWORD(1,1);
WSADATA wsaData;
int nRet;

//
// Initialize WinSock and check the version
//
nRet = WSAStartup(wVersionRequested, &wsaData);
if (wsaData.wVersion != wVersionRequested)
{
fprintf(stderr,"\n Wrong version\n");
return 0;
}


int sd, rc, i;
struct sockaddr_in localAddr, servAddr;
struct hostent *h;

if(argc < 3) {
printf("usage: %s <server> <data1> <data2> ... <datan>\n",argv[0]);
exit(1);
}


// The gethostbyname() function is used when we have the DNS name of our server
h = gethostbyname(argv[1]);
if(h==NULL) {
printf("%s: unknown host '%s'\n",argv[0],argv[1]);
exit(1);
}

//
// Fill in the address structure
//

servAddr.sin_family = h->h_addrtype;
memcpy((char *) &servAddr.sin_addr.s_addr, h->h_addr_list[0], h->h_length);
servAddr.sin_port = htons(SERVER_PORT);

/* create socket */
sd = socket(AF_INET, SOCK_STREAM, 0);
if(sd<0) {
perror("cannot open socket ");
exit(1);
}

/* bind any port number */
localAddr.sin_family = AF_INET;
localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
localAddr.sin_port = htons(0);

rc = bind(sd, (struct sockaddr *) &localAddr, sizeof(localAddr));
if(rc<0) {
printf("%s: cannot bind port TCP %u\n",argv[0],SERVER_PORT);
perror("error ");
exit(1);
}

/* connect to server */
rc = connect(sd, (struct sockaddr *) &servAddr, sizeof(servAddr));
if(rc<0) {
perror("cannot connect ");
exit(1);
}
