In the Magento admin, I would like to do some changes in the following files.
- app\code\core\Mage\Adminhtml\Block\Customer\Grid.php
- app\code\core\Mage\Adminhtml\controllers\CustomerController.php
- app\code\core\Mage\Adminhtml\Helper\Data.php
How can I extend these changes and implement without touching the core files. I have searched in google but i couldn't find the solutions.
Awaiting for valuable reply

Follow below steps, create one custom module
app/code/local/Custom/Module/etc/config.xml
app/code/local/Custom/Module/Block/Adminhtml/Customer/Grid.php
app/code/local/Custom/Module/Helper/Adminhtml/Data.php
app/code/local/Custom/controllers/CustomerController.php
And finally declare your module
app/etc/modules/Custom_Module.xml
