===100分求助几个着急的问题===

sunsfq 2003-09-15 12:46:19
(1)获取硬盘序列号/cpu型号的函数
(2)CSocket通讯中,客户端服务器端一旦连接成功后,会不会出现中断
要是长时间连接,如何保证不出现错误
(3)socket通讯中在定时器函数中发送数据可行么?

(2)CSocket通讯中,客户端服务器端一旦连接成功后,会不会出现中断
要是长时间连接,如何保证不出现错误

可以自己从CSocket派生一个带定时器的CSocketX;
关键时重载OnMessagePending()事件

BOOL CSocketX::OnMessagePending()
{
MSG msg;

// Watch for our timer message
if(::PeekMessage(&msg, NULL, WM_TIMER, WM_TIMER, PM_NOREMOVE))
{
// If our timer expired...
if (msg.wParam == (UINT) m_nTimerID)
{
// Remove the message
::PeekMessage(&msg, NULL, WM_TIMER, WM_TIMER, PM_REMOVE);
// And cancel the call
CancelBlockingCall();
return FALSE;
}
}
// Call base class function
return CSocket::OnMessagePending();
}

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
