How can I do this in C ++ 

  Interface activator {zero action perfender ( ); } JButton.addActionListener (New Executioner) {Zero ActionPerfed () {Something}});   
 So far I know this,    class ActionListener {Public: Virtual ~ ActionListener () {} Virtual Zero Action Methodology () = 0; }   
 What can I do next ... Any such keywords will also help to implement this kind of implementation.   
 
 
 C ++ is not really an unknown class as you find in Java The general thing is simply declaring a subclass The interface is obtained from the class. The closest you find in an example of an unknown class of Java:  
  Category: Public ActionList {Public: Virtual Zero Action Perf. () {// Something}} Listener; Thing.addActionListener (listener);

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
