- Where Developers Learn, Share, & Build Careers


I'm making my first Windows Mobile application I have a login screen - I'm just wandering, 24 hours a day How does the user sign in, where will it ask for a username and password?

The application was opened / closed during the day, and I only want to put my certificate in the morning. Thank you

You can capture the database for the first time, and check the time separately from the first log You can. Time, if time varies more than 24 hours, delete the row in the table

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 -

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.
