How to use MSyncMLEventObserver ?

[strike_noir]

Hi FN


I'm trying to notify my application when a sync job i started has finished syncing. So i used MSyncMLEventObserver just like this.

	// Open syncML session
	RSyncMLSession syncMLSession;
	syncMLSession.OpenL();
	syncMLSession.RequestProgressL(*this);
	// Need instance of data sync class
	RSyncMLDataSyncJob job;
	// For creating a data sync job, need to specify id of the profile used for synchronization
	// If profile selected is PCSuite, it searches for the bluetooth device to sync with
	job.CreateL( syncMLSession,aActiveProfile);
	// close the job
	job.Close();
	// close the syncML session
	syncMLSession.Close();

But the OnSyncMLSyncProgress, OnSyncMLSyncError, OnSyncMLDataSyncModifications of MSyncMLEventObserver is never called.

How to make the MSyncMLEventObserver's functions called?

When a session is closed, the event observer will also be cancelled so you need to keep the session open until the job is at least complete, though in practice you just keep the session open throughout the lifetime of the application.

Hi Paul


Yes i need to keep the session open until the job is finished.

So i changed it to this

	RSyncMLSession iSyncMLSession;
	iSyncMLSession.OpenL();
	iSyncMLSession.RequestProgressL(*this);
	RSyncMLDataSyncJob iJob;
	iJob.CreateL( iSyncMLSession,aActiveProfile);
	iJob.Close();
	
	if(iWaitDialog)
	{
		iWaitDialog->ProcessFinishedL(); 
		iWaitDialog = NULL;
	}
	iWaitDialog = new (ELeave) CAknWaitDialog(
     (REINTERPRET_CAST(CEikDialog**, &iWaitDialog)), 
     ETrue);
	iWaitDialog->PrepareLC(R_FILELIST_WAIT_NOTE);
	iWaitDialog->SetTextL(KNullDesC);
	iWaitDialog->RunLD();

The app panicked with KERN-EXEC 0. Then i cleared all the MSyncMLProgressObserver but it still panicked with KERN-EXEC 0, unless i commented "iSyncMLSession.RequestProgressL(*this);"

void CSyncHandler::OnSyncMLSyncError (TErrorLevel aErrorLevel, TInt aError, TInt aTaskId, TInt aInfo1, TInt aInfo2)
	{
	}

void CSyncHandler::OnSyncMLSyncProgress (TStatus aStatus, TInt aInfo1, TInt aInfo2)
	{
	}

void CSyncHandler::OnSyncMLDataSyncModifications (TInt aTaskId, const TSyncMLDataSyncModifications &aClientModifications, const TSyncMLDataSyncModifications &aServerModifications)
	{
	}

What could be wrong here?

Hmm it worked now. I got some stupid mistakes.
