Re: Activate the request after hours using Acive abjects

Why not simply implement a counter for half-hours? If you have to wait e.g. for 3 hours, set the counter to 6, set the wait period for After() to half an hour, decrement the counter whenever After() returns, and if the counter is not yet zero, wait another half hour with After().

iXMLEngine->GenerateXML(ELocationMessage);
}

After(iInterval);
}
else
CActiveScheduler::Stop();
}

void CScheduleTimer::ConstructL(CSmsHandler *iSmsHandler, TTimeIntervalMicroSeconds32 aInterval)
{
CActiveScheduler::Add(this);
iTimer.CreateLocal();
this->iInterval = aInterval;
iXMLEngine = NULL;

this->iSmsHandler = iSmsHandler;

After(iInterval);
}

void CScheduleTimer::After(TTimeIntervalMicroSeconds32 aInterval)
{

Create your own timer class which encapsulate the call to RTimer and do as RBrunner wrote (i.e. split the time to wait in 35minutes chunk and add a counter). I have done this for one project and it works very well.

Alternatively your can use RTimer::At() for long delays (e.g. Alarms).

Why have a timer that goes off every 1/2 hour and then do some calculation when as fig7 says you can use At()?

Re: Activate the request after hours using Acive abjects

RTimer::At() is really useful. I used it to launch a request at a particular time,and also my application ran in background.My CMyTimer::Start(TTime& aTime) function ws like this:
{
......
At(aTime);
......
}
And at the right time to user iMyTimer->Start(time); then it will go into the RunL() function to do the required job.
