LOok at my code. When i compile it and it does the recieve command i get the error: INVALID_SOCKET! any ideas?

  
#include <stdio.h>
#include <winsock2.h>
#include <iostream.h>
int main(int argc, char* argv[])
{
	cout <<"The Nonamed Game Server Version 0.1a\nBy:Matthew Shapiro\n\n";
	unsigned long ul=1;
	sockaddr_in me;
	WSADATA wsaData;
	SOCKET s;
	const int max_length=25;
	char namebuf[max_length];
	char passbuf[max_length];
	char username;
	char password;
	int error = 0;
	int nRet;
	if(error = WSAStartup(MAKEWORD(2,0), &wsaData))
	{
		switch(error)
		{
		case WSASYSNOTREADY:
			printf("WSASYSNOTREADY\n");
		case WSAVERNOTSUPPORTED:
			printf("WSAVERNOTSUPPORTED\n");
		case WSAEINPROGRESS:
			printf("WSAEINPROGRESS\n");
		case WSAEPROCLIM:
			printf("WSAEPROCLIM\n");
		case WSAEFAULT:
			printf("WSAEFAULT\n");
	};		return 1;
	}
	s = socket(AF_INET, SOCK_DGRAM, 0);
    if (s == INVALID_SOCKET)
    {
        printf("socket() failed; %d\n", WSAGetLastError());
        return 1;
    }
	nRet = ioctlsocket(s,FIONBIO, (unsigned long *) &ul);
	if (nRet == SOCKET_ERROR)
	{
		cout <<"failed to put socket into nonblocking mode: "<<WSAGetLastError<<''\n'';
		return 1;
	}
	me.sin_family = AF_INET;
	me.sin_port = htons(5151);
	me.sin_addr.s_addr = htonl(INADDR_ANY);
	cout <<"Testing\n";
	if (bind(s, (SOCKADDR *)&me, sizeof(me)) == SOCKET_ERROR)
	{
		cout <<"bind() failed: ";WSAGetLastError();
		return 1;
}

	int err = recv(s,namebuf,25,0);
	if (err==0 || err==INVALID_SOCKET)
	{
		cout <<"Couldn''t recieve username: "<<WSAGetLastError()<<''\n'';
		return 1;
}
	username;
	err = recv(s,passbuf,25,0);
	if (err==0 || err==INVALID_SOCKET)
	{
		cout <<"Couldn''t recieve password: "<<WSAGetLastError()<<''\n'';
		return 1;
}
	cout <<"everything works right now\n";
password;
return 1; 
}
  

with nonblocking sockets, be sure to check for a WSAEWOULDBLOCK return value.
