Hiding an Application from the Task List

Hi all,

I'm reading "forum nokia technical solution v1.7", in section 4.23 there's an article about "How can I hide an application from the task list?" which has the following code :

TInt wgId = iEikonEnv->RootWin().Identifier();
RWsSession session = iEikonEnv->WsSession();
CApaWindowGroupName* wgName = CApaWindowGroupName::NewLC(session, wgId);
wgName->SetHidden(ETrue);
wgName->SetWindowGroupName(iEikonEnv->RootWin());
CleanupStack::PopAndDestroy(); // wgName

What is Task List exactly? and how can I found it?


..I've tried the above code, I place it in AppUi, but it has no effect at all, I have a TASK SPY application, I can still kill the application

Does anyone know why? If someone already tried the above code and succeed, please share it with us.

Thank you

Irma
