how to generate qr code in asp.net core

Here 10/3 is 3 because the result is rounded down. But 3 3 is 9, so you get a remainder of one. When you divide 9 by 3, the result is exactly 3, with no rounding. Therefore, the remainder is zero. This may be useful if you want to check something every 10 minutes as in the recipe earlier in the chapter. You can simply check whether minute % 10 is zero. (For a description on how to do this, see the sidebar Sneak Peek: The if Statement, later in the chapter.) As you can see from the final example, the remainder operator works just fine with floats as well. The last operator is the exponentiation (or power) operator: >>> 2 ** 3 8 >>> -3 ** 2 -9 >>> (-3) ** 2 9 Note that the exponentiation operator binds tighter than the negation (unary minus), so -3**2 is in fact the same as -(3**2). If you want to calculate (-3)**2, you must say so explicitly.

At this point, we re interested in only the index action and the corresponding view. Open app/controllers/catalog_controller.rb, which was just created by the generator command. Modify the index method so that it looks as follows: def index @page_title = "Book List" @book_pages, @books = paginate :books, :per_page => 10, :include => [:authors, :publisher], :order => "books.id desc" end

(shown in bold in previous sample return set: customer_id should be address_id . is_default_billing always returns false. is_default_shipping always return false.

In the index action, we first set the page title so that the layout file will pick it up and show it in the headers of the resulting page. Additionally, the action contains a normal pagination call, just as in 3. However, this time, we use the include parameter for the paginate call. The include parameter is used in the ActiveRecord find method (which is used internally by paginate) to make ActiveRecord build up a join query. This single SQL query will be used not only to find the books, but also to fetch the associated authors and publishers from the database. If we omitted the parameter, our code would end up calling a new SQL query each time we needed to get the author or publisher details for a given book. In our case, it would result in 2n+1 (where n is the number of books) queries instead of just one. When the site gets more traffic, that could become a huge performance bottleneck.

Python can handle really large integers: >>> 1000000000000000000 1000000000000000000L What happened here The number suddenly got an L tucked onto the end.

Because we ran across this bug during one of my projects, we provide the fix here. To change customer_id to address_id : Open up this file: \app\code\core\Mage\Customer\Model\Address\Api.php Replace line 37 'customer_id' => 'entity_id' with this: 'address_id' => 'entity_id' To fix the is_default_billing and is_default_shipping bug: Open up this file: \app\code\core\Mage\Customer\Model\Address\Api.php Replace line 77 and 78 with this: $row['is_default_billing'] = $customer->getDefaultBillingAddress()->entity_id == $address->getId(); $row['is_default_shipping'] = $customer->getDefaultShippingAddress()->entity_id == $address->getId();
