CeSetUserNotificationEx和CeRunAppAtTime都使用不了？怎么回事呢。

[JimsdogV1]

友善的TQ2440开发板上，测试使用CeSetUserNotificationEx，代码如下，如果提醒时间设成10秒会马上提醒，如果设成大于10秒则一直不会产生提醒，希望有使用CeSetUserNotificationEx成功的兄弟指点一二。

HANDLE				h_notify;
HANDLE				h_Event;
bool				b_started;

b_started = false;
h_notify = NULL;

void CNotificationDlg::Test_Thread(LPVOID lp)
{
	CNotificationDlg* p_owner = (CNotificationDlg*)lp;
	while(p_owner->b_started)
	{
		if(p_owner->h_Event != NULL)
		{
			TRACE(L"h_Event is not NULL\r\n");
			if(WaitForSingleObject(p_owner->h_Event,INFINITE) == WAIT_OBJECT_0)
			{
				TRACE(L"TIME OK\r\n");
			}else
				TRACE(L"error\r\n");
		}else
		{
			TRACE(L"h_Event is NULL\r\n");
		}
	}
}

void CNotificationDlg::OnBnClickedButton1()
{
	// TODO: 在此添加控件通知处理程序代码
/*	SYSTEMTIME curTime;
	GetLocalTime(&curTime);
	curTime.wMinute++;*/

	CE_NOTIFICATION_TRIGGER	trigger;
	memset(&trigger, 0, sizeof(trigger));
	
	trigger.dwSize = sizeof(CE_NOTIFICATION_TRIGGER);
	trigger.dwType = CNT_EVENT;
//	trigger.dwEvent = NOTIFICATION_EVENT_NET_DISCONNECT;
//	trigger.dwEvent = NOTIFICATION_EVENT_NONE;
//	trigger.dwEvent = NOTIFICATION_EVENT_TIME_CHANGE;
	trigger.dwType = CNT_TIME ;
//	trigger.dwEvent = NULL;
	trigger.lpszApplication = _T("\\\\.\\Notifications\\NamedEvents\\MyTestEvent\0");
	trigger.lpszArguments = NULL;

/*	SYSTEMTIME curSysTime;
	SYSTEMTIME endSysTime;

	GetLocalTime(&curSysTime);

	curSysTime.wMinute += 1;
	endSysTime = curSysTime;
	endSysTime.wMinute += 1;
//	endSysTime.wYear += 10;*/
	SYSTEMTIME old_SysTime, new_SysTime;
	FILETIME old_FileTime, new_FileTime;
	GetLocalTime(&old_SysTime);
	SystemTimeToFileTime(&old_SysTime, &old_FileTime);
	ULONG timeInterval = 70;
	ULONGLONG interval = (((ULONGLONG)old_FileTime.dwHighDateTime) << 32) + old_FileTime.dwLowDateTime  
	  + ((ULONGLONG)timeInterval)*1000*10000; // 10秒以后执行应用
	new_FileTime.dwHighDateTime = (DWORD)(interval >> 32);
	new_FileTime.dwLowDateTime = (DWORD)(interval & 0xFFFFFFFF);[code=C/C++]

FileTimeToSystemTime(&new_FileTime, &new_SysTime);

trigger.stStartTime = new_SysTime;
new_SysTime.wHour++;
trigger.stEndTime = new_SysTime;

h_Event = CreateEvent(NULL, FALSE, FALSE, _T("MyTestEvent"));
if(NULL == h_Event)
{
TRACE(L"h_Event is NULL\r\n");
return;
}
if(NULL == h_notify)
{
h_notify = CeSetUserNotificationEx(0,&trigger,NULL);
}else
{
h_notify = CeSetUserNotificationEx(h_notify,&trigger,NULL);
}
if(NULL == h_notify)
{
TRACE(L"h_notify is NULL\r\n");
return;
}
if(!b_started)
{
b_started = true;
AfxBeginThread((AFX_THREADPROC)Test_Thread,(LPVOID)this);
}
}
[/code]
后来放弃CeSetUserNotificationEx而用CeRunAppAtTime，却照样指定程序得不到运行，而CeRunAppAtTime又是返回成功的。代码如下：

SYSTEMTIME st = {0};
	CString tempppp;
	CTime t = CTime::GetCurrentTime();
	t.GetAsSystemTime(st);
	tempppp.Format(L"%d-%d-%d\r\n",st.wHour,st.wMinute,st.wSecond);
	TRACE(tempppp);
	CTimeSpan diff(0, 0, 2, 10);
	t += diff;
	t.GetAsSystemTime(st);
	tempppp.Format(L"%d-%d-%d\r\n",st.wHour,st.wMinute,st.wSecond);
	TRACE(tempppp);
	TCHAR szXmlPath[MAX_PATH] = {0};
	xhGetExePath(szXmlPath);
	_tcscat(szXmlPath, L"\\notify.exe");
	BOOL m_btemp = CeRunAppAtTime(szXmlPath,&st);
	if(m_btemp)
		TRACE(L"CeRunAppAtTime success!\r\n");
	else
		TRACE(L"CeRunAppAtTime fail!\r\n");

希望有经验的兄弟指点指点啊，不想用定时器，太不准了。

楼上的代码是微软MSDN上的吧，那是用的系统事件提醒trigger.dwType = CNT_EVENT;
而我想用的是 trigger.dwType = CNT_TIME ;啊
