奇怪，AfxBeginThread创建UI线程失败,并抛出访问非法内存的异常

[songpingbo]

m_pMsgProcThread = AfxBeginThread(RUNTIME_CLASS(CMsgProcThread),
THREAD_PRIORITY_NORMAL,
0,
CREATE_SUSPENDED);

CMsgProcThread是CWinThread的子类，CMsgProcThread类的头文件中有
DECLARE_DYNCREATE(CMsgProcThread)

CMsgProcThread的实现文件中有：
IMPLEMENT_DYNCREATE(CMsgProcThread, CWinThread)



这么会出这样的事呢？查了半天的资料没有找到为什么啊？

你单步调试看看

[songpingbo]

单调调度的时候发现在是AfxBeginThread()在调用CreatThread的下面第二个VERIFY出现的内存异常：

// start the thread just for MFC initialization
VERIFY(ResumeThread() != (DWORD)-1);
VERIFY(::WaitForSingleObject(startup.hEvent, INFINITE) == WAIT_OBJECT_0);
::CloseHandle(startup.hEvent);

[Y神圣]

你什么时候Resume的这个线程？

[songpingbo]

//启动超时管理线程
m_pTimerMngrThread = AfxBeginThread(RUNTIME_CLASS(CTimerMngThread));
if (!m_pTimerMngrThread)
{
CA_TRC_ERR(DBGW_LOG_CTRL_APP_FRAME, "启动超时管理器失败！");
return FALSE;
}

m_pTimerMngrThread->m_bAutoDelete = FALSE;

//启动事件调度线程；
m_hEventDispatchThread = (HANDLE)_beginthreadex(NULL,0,DispatchEvent,(void *)(&m_CasDb[1]),0,NULL);
if (!m_hEventDispatchThread)
{
CA_TRC_ERR(DBGW_LOG_CTRL_APP_FRAME, "启动事件调度失败!");
return FALSE;
}

//启动消息处理线程
m_pMsgProcThread = AfxBeginThread(RUNTIME_CLASS(CMsgProcThread),
THREAD_PRIORITY_NORMAL,
0,
CREATE_SUSPENDED);
if (!m_pMsgProcThread)
{
CA_TRC_ERR(DBGW_LOG_CTRL_APP_FRAME, "启动消息处理器失败!");
return FALSE;
}

m_pMsgProcThread->m_bAutoDelete = FALSE;

CMsgProcThread::SetCasDb(m_pMsgProcThread,m_CasDb);
m_pMsgProcThread->ResumeThread();

Try to use CreateThread

[Big_Stone]

干什么这么麻烦，给个EMAIL，给你个比较稳定的线程封装类。

[吴双1983]

HANDLE hThread=CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)SearchFile,NULL,0,NULL);
CloseHandle(hThread);

UINT SearchFile(LPVOID lpParam)
{
return 0;
}

刚创建线程对象就出错，莫非你的CMsgProcThread类构造函数中有非法访问内存语句？
