 After(timeout_interval) ;

SetActive() ; // mega-crash but why???

I bet it is a E32USER-CBase 42 panic. SetActive() was already called in CTimer::After(...).

Read the documentation for CTimer, it says you have to provide an implementation of RunL(), where is it?

I think you should understand the basics of the Active Shecduler (AS) first. Hope there are plenty of articles available from NewLC tutorials and Forum Nokia Wiki, just do a search. Before calling SetActve you should call an asynchronous function where in which you should pass the iStatus (which is an object of CActive a TRequestStust type).

The next thing is you've some misconception on CounstructL(). A part of code in ConstructL() should be moved to the NewL()/NewLC() function. AFAIK your ConstructL() can't return any value, you can call any of the leaving functions inside it. Search for Two-Phase construction and CleanupStack. Another observation is that you've not followed the Symbian naming conventions properly.

I would recommend you to check any of the implementation of CTimer with SDK Help to get know more about it.

Hi all,

I want to make this timer work but it crashes on SetActive() command.

Class symbian_timer_helper is derived from : public CTimer. It crashes but does not even run RunL() command of CTimer! It does not even start the timer if I remove SetActive().

Here is the code:

void symbian_timer_helper::base_constructL()
{
CTimer::ConstructL() ;
}
