关于系统登录之前的网络的!!有问题!!

Question

win2000在登录之前已经配好了网络,能用socket编程了,
但是winxp,在登录之前,网络配好了吗?
能用socket编程吗?
我试过win2K,次次都能socket编程,但是,winxp有时能
有时不能,希望各位大侠解释一下,谢谢!
注:我是在学Gina编程!

Answer 1

Win2000没有问题的话,Winxp也应该没有问题,在登录之间网络肯定已经配置好了

Answer 2

我试过在gina中进行网络操作.
给一段代码你吧.用的是UDP方式,线程启动.
#include <winsock2.h>
#pragma comment(lib,"ws2_32.lib")UINT WorkThread(LPVOID param)
{
SOCKET s;
sockaddr_in addrto;
WSADATA wsdata;
BOOL bsocket;
char *smsg="Cenxi Gbpc";
//&AElig;&ocirc;&para;&macr;SOCKET&iquest;&acirc;&pound;&not;°&aelig;±&frac34;&Icirc;&ordf;2.0
WSAStartup(0x0202,&wsdata);

s=WSASocket(AF_INET,SOCK_DGRAM,0,NULL,0,WSA_FLAG_OVERLAPPED);
bsocket=TRUE;
    //&Egrave;&raquo;&ordm;ó&cedil;&sup3;&Ouml;&micro;&cedil;&oslash;&micro;&Oslash;&Ouml;·&pound;&not;&Oacute;&Atilde;&Agrave;&acute;&acute;&Oacute;&Iacute;&oslash;&Acirc;&ccedil;&Eacute;&Iuml;&micro;&Auml;&sup1;&atilde;&sup2;&yen;&micro;&Oslash;&Ouml;·&frac12;&Oacute;&Ecirc;&Otilde;&Iuml;&ucirc;&Iuml;&cent;&pound;&raquo;
addrto.sin_family=AF_INET;
    addrto.sin_addr.s_addr=INADDR_BROADCAST;
addrto.sin_port=htons(5050);
bool opt=true;
//&Eacute;è&Ouml;&Atilde;&cedil;&Atilde;&Igrave;×&frac12;&Oacute;×&Ouml;&Icirc;&ordf;&sup1;&atilde;&sup2;&yen;&Agrave;à&ETH;&Iacute;&pound;&not;
setsockopt(s,SOL_SOCKET,SO_BROADCAST,(char FAR *)&opt,sizeof(opt));
int nlen=sizeof(addrto);
while(1)
{
Sleep(5000);
//&acute;&Oacute;&sup1;&atilde;&sup2;&yen;&micro;&Oslash;&Ouml;··&cent;&Euml;&Iacute;&Iuml;&ucirc;&Iuml;&cent;
int ret=sendto(s,smsg,256,0,(sockaddr*)&addrto,nlen);
//if(ret==SOCKET_ERROR)
// MessageBox(NULL,"Error!","Warning!",MB_OK);//cout<<WSAGetLastError()<<endl;
