How to set Magento store config data programmatically?

Question

To get store config data, I would use this code:

$data = Mage::getStoreConfig('my/path/whatever'); 

Now, how could I save to that node? I tried Alans suggestions from Override Magento Config, but it did not work for me.

Thanks!

Try following:

$value = "100";
Mage::getModel('core/config')->saveConfig('my/path/whatever', $value);

OR

$resource = $this->getResourceModel();
$resource->saveConfig(rtrim('my/path/whatever', '/'), 1, 'default', 0);

Empire Solution is right but do remember to clean cache after it. So use something like

$value = "100";
Mage::getModel('core/config')->saveConfig('my/path/whatever', $value);
Mage::getModel('core/config')->cleanCache();
