Difference Between Disable Module Output and Module Active in Magento 1.9

configurationmagento-1.8magento-1.9module

In magento I come to knew that we can disabel our module by two ways

By navigating in the Magento backend to System > Configuration > Advanced > Disable modules output we can easily disable certain modules.
In the directory app/etc/modules, by changing the active-tag from true to false.

May I know what is the exact difference in these two technic?
Its very help if anyone give more detailed Answer.

System > Configuration > Advanced > Disable Modules Output will not actually disable that module. It work as the name suggest, disable modules output.

When you look at

abstract class Mage_Core_Block_Abstract

final public function toHtml()
{
    Mage::dispatchEvent('core_block_abstract_to_html_before', array('block' => $this));
    if (Mage::getStoreConfig('advanced/modules_disable_output/' . $this->getModuleName())) {
        return '';
    } 

// It is checking If its in disabled mode then just return blank output
.......
}

While app/etc/modules completely disabled module

Magento 1.8 – Difference Between htmlEscape and escapeHtml Functions

The answer is found in the class where it is defined: app/code/core/Mage/Core/Block/Abstract.php

So it seems that some time after version CE 1.4.0.0-rc1 they decided that htmlEscape should be renamed to escapeHtml.

#File: app/code/core/Mage/Core/Block/Abstract.php
/**
 * @deprecated after 1.4.0.0-rc1
 * @see self::escapeHtml()
 */
public function htmlEscape($data, $allowedTags = null)
{
    return $this->escapeHtml($data, $allowedTags);
}

/**
 * Escape html entities
 *
 * @param   mixed $data
 * @param   array $allowedTags
 * @return  string
 */
public function escapeHtml($data, $allowedTags = null)
{
    return $this->helper('core')->escapeHtml($data, $allowedTags);
}

Magento 1.8 – Difference Between getChildHtml and getBlockHtml

getBlockHtml('block_name_here') get's you the html of the block with name block_name_here if it finds it in the layout...anywhere.
getChildHtml('block_name_here') get's you the html of the block with name block_name_here only if that block is a child of the current block.

Here is an example. Consider the next layout section

<block type="core/template" template="some_template.phtml" name="some_name" />
<block type="core/template" template="some_other_template.phtml" name="some_other_name" />

Now in the template file some_template.phtml if you add this line of code <?php echo $this->getBlockHtml('some_other_name')?> you will get the html for the block some_other_name.
If you add <?php echo $this->getChildHtml('some_other_name')?> you will get nothing.

IN the following scenario

<block type="core/template" template="some_template.phtml" name="some_name">
    <block type="core/template" template="some_other_template.phtml" name="some_other_name" />
</block>

getChildHtml and getBlockHtml will get you the same thing. the html of the block some_other_name.
