hi i found this code at
Johnnies winsock tutorial
Code:
#pragma comment (lib,"wsock32.lib")

// Next, create the listening socket

if (listeningSocket == INVALID_SOCKET) {
nret = WSAGetLastError(); // Get a more detailed error
ReportError(nret, "socket()"); // Report the error with our custom function

// and insert into the port field
// Bind the socket to our local server address
nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr_in));
if (nret == SOCKET_ERROR) {
nret = WSAGetLastError();
ReportError(nret, "bind()");

return NETWORK_ERROR;
}
// Make the socket listen

}
// Wait for a client

WSACleanup();
return NETWORK_OK;
}
void ReportError(int errorCode, const char *whichFunc) {
char errorMsg[92]; // Declare a buffer to hold
// the generated error message
ZeroMemory(errorMsg, 92); // Automatically NULL-terminate the string
// The following line copies the phrase, whichFunc string, and integer errorCode into the buffer
sprintf(errorMsg, "Call to %s returned error %d!", (char *)whichFunc, errorCode);
MessageBox(NULL, errorMsg, "socketIndication", MB_OK);
}
i get an error that says call to bind() returned error 1048
1048 is the error# that u can find
here
can anyone see whats wrong?
btw what i would want to do is an app that sends a text message when u connect to it
