知道一條資訊的TMsvId,如何開啟資訊瀏覽視圖

 知道一條資訊的TMsvId，想開啟資訊瀏覽視圖，主要用如下代碼實現：

void CMtmEngine::OpenMessage(TMsvId aId){   TMsvEntry msgEntry; // class that represents the entry (a local cache)   TMsvId ownerServiceId;      if( iSession->GetEntry( aId,ownerServiceId, msgEntry )         != KErrNone )   return;   CClientMtmRegistry *cltReg = CClientMtmRegistry::NewL( *iSession );   CleanupStack::PushL( cltReg );   CBaseMtm *mtm = cltReg->NewMtmL( msgEntry.iMtm );   CleanupStack::PushL( mtm );   CMtmUiRegistry *reg = CMtmUiRegistry::NewL( *iSession );   CleanupStack::PushL( reg );   CBaseMtmUi *ui = reg->NewMtmUiL( *mtm );   CleanupStack::PushL( ui );   mtm->SwitchCurrentEntryL( msgEntry.Id() );   //Editor are embedded.   ui->SetPreferences( EMtmUiFlagEditorPreferEmbedded );   CMsvOperationActiveSchedulerWait *waiter = CMsvOperationActiveSchedulerWait::NewLC();   CMsvOperation* op = ui->ViewL( waiter->iStatus );   waiter->Start();   delete op;   CleanupStack::PopAndDestroy( 5, cltReg );}
