Get running Order Increment Id in magento

$orders = Mage::getModel('sales/order')->getCollection()
        ->setOrder('increment_id','DESC')
        ->setPageSize(1)
        ->setCurPage(1);
$orderId = $orders->getFirstItem()->getIncrementId();

OR

$orderId = Mage::getSingleton('eav/config')->getEntityType('order')->fetchNewIncrementId($this->getQuot
e()->getStoreId());
