First off, a subroutine isn’t passed the @ARGV array. Rather all the parameters passed to a subroutine are flattened into a single list represented by @_ inside the subroutine. The @ARGV array is available at the top-level of your script, containing the command line arguments passed to you script. Now, in Perl, when you call … Read more
If you are adding the columns yourself… don’t add the columns you don’t want. If you have AutoCreateColumns enabled, then: if it is a class-based model, add [Browsable(false)] to properties you don’t want or set the column’s .Visible to false or simply remove the columns you don’t want afterwards
What do defer and async mean? By default, a <script src=…></script> tag is evil! The browser must halt parsing the HTML until the script is downloaded and executed (since the script might call document.write(…) or define global variables that later scripts depend on). This means that any images and stylesheets that are after the script … Read more
Whenever you have a product object, you can access its attribute set like this: $attributeSetModel = Mage::getModel(“eav/entity_attribute_set”); $attributeSetModel->load($product->getAttributeSetId()); $attributeSetName = $attributeSetModel->getAttributeSetName(); This will give you the name of the attribute set, which you can then compare using strcmp: if(0 == strcmp($attributeSetName, ‘My Attribute Set’)) { print $product->getAttributeText(‘attribute’); }
setAttribute() is a DOM 1 function. setAttributeNS() is a DOM 2 function that resolves the problem of conflicting tag or attribute names by specifying the xmlns namespace that should apply to the tag/attribute in the first argument. If an attribute does not have a defined namespace prefix, the first argument must be null. You could … Read more
Based on the variety of answers, Class “attributes”, “fields”, and “variables” are used relatively interchangeably but have nuanced distinctions that vary from person to person. As such, probably best to lump them together and not rely on the nuances. There’s consensus that a Class “member” includes methods as well as data, so it is distinct … Read more
To return entries that contain a populated status attribute, use a present filter, for example, (status=*). To return entries that do not contain a status attribute, negate the present filter: (!(status=*)). If the server is unwilling to execute, check that the status attribute is indexed for equality and presence. If do not have access to … Read more
You’re trying to create a delegate from an instance method, but you’re not passing in a target. You could use: Delegate.CreateDelegate(typeof(TestDelagate), this, method); … or you could make your method static. (If you need to cope with both kinds of method, you’ll need to do that conditionally, or pass in null as the middle argument.)
