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");
