c++ - Appropriate use of friend? Container class designed to manipulate objects of specific type -

June 15, 2014

You say that you have a FooManager to manage many types of objects Foo . FooManager needs to see parts of its Foo s to evaluate its current state before I see Foo < / Code> was using some accessories, until I realized that FooManager is actually the only class using these. I decided to make a friend of FooManager to Foo . As a result most of the classes Foo become private.

  Is this a friend's fair use? My reasoning was that it helps in encapsulation because when it gives full access to the interior of  FooManager  to  Foo , then it will completely stop access to everything else. Does.

  
  Unless you are trying to achieve, there is no separate and cleaner way, It seems like a proper approach. 
  In relation to the encapsulation, see:.

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.      I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

php - How do I set up pagination for an image gallery with image

    I have two tables:    gallery id | Name | Details Image ID | Title | Caption | Gallery ID    By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
