There's a CenRep key KCoreAppUIsNetworkConnectionAllowed that can be used for detecting off-line mode.

#include <CoreApplicationUIsSDKCRKeys.h>

To ask one time:

  TInt aOfflineModeOff(0);
  // Connecting and initialization:
  CRepository* repository = CRepository::NewL(KCRUidCoreApplicationUIs);
  // Check offline mode on or not.
  if (repository->Get(KCoreAppUIsNetworkConnectionAllowed, aOfflineModeOff) == KErrNone)
     {
     // Do something based on the aOfflineModeOff value
     }
  delete repository;
You might want to order notifications about the changes: 
 
    iRepository = CRepository::NewL(KCRUidCoreApplicationUIs);
    iCenRepNotifyHandler = 
         CCenRepNotifyHandler::NewL(*this, *iRepository,
            CCenRepNotifyHandler::EIntKey, KCoreAppUIsNetworkConnectionAllowed);
    iCenRepNotifyHandler->StartListeningL();
 
void CThisClass::HandleNotifyInt(
    TUint32 aId,
    TInt aNewValue )
    {
    if (aId == KCoreAppUIsNetworkConnectionAllowed)
       {
       // Do something based on the aNewValue
       }
    }
 
// Remeber to delete created objects in the destructor

Another way to query the profile is to use the Profiles Engine Wrapper API:

#include <proengfactory.h>
#include <mproengengine.h>
MProEngEngine* engine = ProEngFactory::NewEngineLC();
TInt profileId = engine->ActiveProfileId();
if (profileId == 5) //offline
    {
    //…
    }
CleanupStack::PopAndDestroy(); //engine
