不能正常工作,当把 ///****
psock=new CSocket;
psock->Create();
psock->Connect("127.0.0.1",7000);
file=new CSocketFile(psock);
arOut=new CArchive(file,CArchive::store);
arIn=new CArchive(file,CArchive::load);****///
放在辅助线程则工作良好,我怀疑是CSocket不能在进程间共享,那位高手帮我一下

[staticip]

CSocket放在不同线程中使用会有很多问题,因为每个线程都有自己的map.

[boymaxzm]

staticip(staticip)你指的map是不是handle和内存地址在每个线程内都有不同的对应关系?

[xiaohyy]

你的问题出在线程之间并未同步，CEvent对象并未正确初始化，
把CEvent cs;改为CEvent cs(TRUE,TRUE);试试

[flagfly]

在不同线程中使用同一socket确实会有很多问题

[redby]

老大，怎么还用CArchive啊，CSocket的Send方法和Receive方法还不够用吗？
pThreadA=AfxBeginThread(printfz,NULL,THREAD_PRIORITY_NORMAL);你传送参数了吗？
你可以把CSocket 实例，作为参数传个子线程啊。我用的时候是没问题的。
如：
//功能函数
void C…::test()
{
CSocket skt;
……

AfxBeginThread(_DealData,&skt);
}
线程函数:
UNIT _DealData(PVOID pv)
{
CSocket *pSkt = (CSocket*)pv;
……
}

改为

to xiaohyy(醉大饿极），我按照你的方法试过了，还是不行啊，唉～～～～

[zoutaiqi]

或者改为

以上各位的方法，小弟都试了一遍，都不行，不知道你们测试了没有
我之所以想用CArchieve，是想偷懒不用关心不同数据类型传送的时候的长度检查，编码和解码的问题
初学者，可能还有其他方法，我看到vc技术内幕上有CBlockSocket那个类写的怎么样？
是不是可以让CBlockSocket 结合CArchieve，来使编程简化，大家有什么高见？
