The we:offset application allows consumers to offset the carbon footprint of their travel using their mobile device. The application includes a "share with a friend" feature accessed from the left soft key and used to allow consumers to encourage their friends to download the application. Here is the code behind that feature:

void CEcoFlyerContainerBase::ShareWithFriendsL()
    {
    CSendUi* sendUi = CSendUi::NewLC();
    CMessageData* data = CMessageData::NewL();
    CleanupStack::PushL( data );
    HBufC* text = HBufC::NewLC( 512 );
    text->Des().AppendFormat( *StringLoader::LoadLC( R_LOC_SMS_SHARING), &KEcoFlyerDownloadLink, &_L( "" ) );
    CleanupStack::PopAndDestroy();
 
    CRichText* richText = CRichText::NewL(
iEikonEnv->SystemParaFormatLayerL(), iEikonEnv->SystemCharFormatLayerL() );
    CleanupStack::PushL( richText );
    richText->InsertL( 0, text->Des() );
    data->SetBodyTextL( richText );
    sendUi->CreateAndSendMessageL( KUidMsgTypeSMS, data );
 
    CleanupStack::PopAndDestroy( 4 );
    }
