多线程的SetEvent问题

[_Wanderer2199]

调试时发现停在了线程函数里面的MyDbgPrintf("1");
while (::WaitForSingleObject(pDialog_Tab3->m_hEvent_CareAllPets, INFINITE))这一句，请教原因!!

void CDialog_Tab3::OnBnClickedCheckAutoCarePets()
{
	// TODO: 在此添加控件通知处理程序代码
	//如果线程句柄为空 创建一个线程
	char sz[5] = { 0 };
	GetDlgItemText(IDC_EDIT_AUTO_CARE_PETS, sz, sizeof(sz));
	if (strlen(sz) == 0)
	{
		MessageBox("请填写时间间隔", "", MB_OK);
		((CButton*)GetDlgItem(IDC_CHECK_AUTO_CARE_PETS))->SetCheck(BST_UNCHECKED);
		return;
	}
	
	if (m_bCheckCareAllPets == FALSE)
	{
		m_bCheckCareAllPets = TRUE;
		((CEdit*)GetDlgItem(IDC_EDIT_AUTO_CARE_PETS))->EnableWindow(FALSE);
		_beginthreadex(NULL, 0, ThreadProc_CareAllPets, this, 0, 0);
		m_hEvent_CareAllPets = CreateEvent(0, FALSE, FALSE, NULL);
		m_hEvent_IsCareAllPetsStop = CreateEvent(0, FALSE, FALSE, NULL);
		SetEvent(m_hEvent_CareAllPets);
		SetTimer(IDT_TIMER_CareAllPets, atoi(sz) * 60000, NULL);
		
		return;
	}

	//如果取消勾选
	m_bCheckCareAllPets = FALSE;
	((CEdit*)GetDlgItem(IDC_EDIT_AUTO_CARE_PETS))->EnableWindow(TRUE);
	SetEvent(m_hEvent_CareAllPets);
	::WaitForSingleObject(m_hEvent_IsCareAllPetsStop,INFINITE);
	MyDbgPrintf("2");
	CloseHandle(m_hEvent_CareAllPets);
	CloseHandle(m_hEvent_IsCareAllPetsStop);
	m_hEvent_CareAllPets = NULL;
	m_hEvent_IsCareAllPetsStop = NULL;
	KillTimer(IDT_TIMER_CareAllPets);
	MyDbgPrintf("取消自动喂宠");

void CDialog_Tab3::OnTimer(UINT_PTR nIDEvent)
{
	switch (nIDEvent)
	{
	case IDT_TIMER_CareAllPets:
		{
			SetEvent(m_hEvent_CareAllPets);
		}
	}
}

unsigned int __stdcall ThreadProc_CareAllPets(void* pArg)
{
	CDialog_Tab3* pDialog_Tab3 = (CDialog_Tab3*)pArg;
	CPet CMyPet;
	MyDbgPrintf("1");
	while (::WaitForSingleObject(pDialog_Tab3->m_hEvent_CareAllPets, INFINITE))
	{
		MyDbgPrintf("3");
		CMyPet.GetData();
		for (int i = 0; i < CMyPet.GetPetNum(); i++)
		{
			MyDbgPrintf("4");
			if (pDialog_Tab3->m_bCheckCareAllPets == FALSE);
			{
				SetEvent(pDialog_Tab3->m_hEvent_IsCareAllPetsStop);
				return 1; 
			}
			while (CMyPet.GetData()->GetPetInfo()[i].PhysicalPower < 1000 || CMyPet.GetData()->GetPetInfo()[i].Mood < 0x5A)
			{
				MyDbgPrintf("5");
				if (pDialog_Tab3->m_bCheckCareAllPets == FALSE);
				{
					SetEvent(pDialog_Tab3->m_hEvent_IsCareAllPetsStop);
					return 1;
				}
				CMyPet.FeedPet(i + 1);
				Sleep(1000);
			}
		}
		MyDbgPrintf("6");
		ResetEvent(pDialog_Tab3->m_hEvent_CareAllPets);
		//提示
		MyDbgPrintf("全部宠物照顾完成!");
	}
}

试试 m_hEvent_CareAllPets = CreateEvent(0, /*FALSE*/TRUE, FALSE, NULL); bManualReset MSDN上的说明 If this parameter is TRUE, the function creates a manual-reset event object, which requires the use of the ResetEvent function to set the event state to nonsignaled. If this parameter is FALSE, the function creates an auto-reset event object, and system automatically resets the event state to nonsignaled after a single waiting thread has been released.

请问前辈如何将两个word组成一个dword 使用的时候我希望用宏loword和hiword分别取出数据

比如我想把【 [ebp - 4] - 44 + 458//大区ID 2字节，[ebp - 4] - 44 + 45A//小区ID 2字节 】这2个数据组成一个DWORD类型，用LOWORD和HIWORD取数据
