-0xC0000008: An invalid handle was specified

高手进---0xC0000008: An invalid handle was specified
本人新手接触VC没多长时间，最近利用异步套接字写了一个服务端，其中调用Release版中MySql接口写入数据库出现以下错误：
0xC0000008: An invalid handle was specified
Debug版出现access violation错误，将Mysql调用部分注释后则无任何问题，还请各位高手帮忙！
调用Mysql代码如下：

C/C++ code

HRESULT CWebUnionServerDlg::OnNetEvent(WPARAM wParam, LPARAM lParam){    int iEvent = WSAGETSELECTEVENT(lParam);    SOCKET CurSock = (SOCKET)wParam;    switch(iEvent)    {    case FD_READ:        {            SOCKADDR_IN sockAddr;            memset(&sockAddr, 0, sizeof(sockAddr));            int nSockAddrLen = sizeof(sockAddr);            getpeername(CurSock, (SOCKADDR *)&sockAddr, &nSockAddrLen);            int nPeerPort = ntohs(sockAddr.sin_port);            CString sPeerIp = inet_ntoa(sockAddr.sin_addr);            char szText[1024] = {0};            recv(CurSock, szText,1024,0);            CString strItem ="["+sPeerIp+"]:" + CString(szText);            AddLog(strItem);            if (!sPeerIp.IsEmpty())            {                LOG_MSG logMsg;                strncpy(logMsg.szText,szText,strlen(szText)+1);                strncpy(logMsg.ipAddr,(char *)((LPCTSTR)sPeerIp),sPeerIp.GetLength()+1);                logMsg.nPort = nPeerPort;                                     //此处发消息调用数据库接口                [color=#FF0000]PostMessage(WM_ADD_DB_LOG,0, (LPARAM)&logMsg);[/color]            }        }        break;    case FD_ACCEPT:        {            if (m_nClient <MAX_SOCKET)            {                SOCKET client = accept(CurSock,NULL,NULL);                int i = WSAAsyncSelect(client, m_hWnd, NETWORK_EVENT, FD_READ|FD_WRITE|FD_CLOSE);                AddClient(client);            }            else            {                MessageBox("Too much client!");            }        }        break;    case FD_CLOSE:        {            RemoveClient(CurSock);            closesocket(CurSock);        }        break;    }        return 0;}

C/C++ code

HRESULT CWebUnionServerDlg::OnAddDbLog(WPARAM wParam, LPARAM lParam){    LOG_MSG * msg = (LOG_MSG *)lParam;    CString strSql ;    char * strStmt = "insert into sys_log (login_ip, login_port, message) values('%s', %d, '%s')";    sprintf((char *)((LPCTSTR)strSql), strStmt, msg->ipAddr, msg->nPort, msg->szText);    //int i = mysql_query(m_dbOpera.m_conn, strSql);    sql::Statement *stmt = m_db.GetStatment(m_conn);    stmt->execute(std::string((LPCTSTR)strSql));    delete stmt;    return 0;}

C/C++ code

    CString strSql;    char * strStmt = "insert into sys_log (login_ip, login_port, message) values('%s', %d, '%s')";    sprintf((char *)((LPCTSTR)strSql), strStmt, msg->ipAddr, msg->nPort, msg->szText);
[解决办法]
Debug下call stack看看函数调用堆栈
[解决办法]
看call stack窗口，找到自己的出错代码。
探讨

你调试运行一下 看看问题出现在哪行代码上

在MFC的文件里面，看不出来是哪出的错

[解决办法]
应该是你调用MySql操作数据库部分的代码有handle错误等
