i'm trying to write an alarm program for PocketPc 6 emulator and for wince 6.0 ,,,,where the alarm time is set by user and at that pirticular time the win mobile has to give some alert message,,,,,

i tried using CeRunAppAtTime and CeSetUserNotification like

HANDLE hNotify;
SYSTEMTIME sysTime,sys;
CE_USER_NOTIFICATION ceNot;
GetSystemTime(&sysTime);//tryed GetLocalTime(&sys); also
sysTime.wHour = 14;
sysTime.wMinute= 20;
sysTime.wSecond= 00;

ceNot.ActionFlags = PUN_SOUND | PUN_VIBRATE | PUN_LED;
ceNot.pwszSound = L"\\Windows\\beep.wav";

hNotify = CeSetUserNotification(NULL,L"\\ResidentFlash\\my.exe",&sysTime,&ceNot);

but here as and when the control comes to this line itself it s performing all actions,,,,,,,,i dont want this kind of functionalities it has to perform action at the specified time,,,,,,,

Plz guide me the correct way to achieve this task,,,,,,,,,any reply s appreciated in advanc开发者_运维百科e,,,,,,thanks,,,,,,,,,


Your notification code is telling the OS to run your application at 14:20:00, so that's what will happen (I assume this is what you mean by "its performing all actions"). If you want it to do only a specific task inside your application, the easiest thing to do is to have it set a named system event like this:

CeSetUserNotification(NULL, 
                      _T("\\\\.\\Notifications\\NamedEvents\\MyAppEvent"), 
                      &time, 
                      &notification);

The same name will work for CeRunAppAtTime. Once you have set up the notification, waiot for the event in your app in a background thread:

hEvent CreateEvent(NULL, FALSE, FALSE, _T("MyAppEvent"));
while(TRUE)
{
    if(WaitForSingleObject(hEvent, 5000) == WAIT_OBJECT_0)
    {
        // the notification has fired.  Do something.
    }
}
