c# - Reader cannot continue after i've checked for records -


I have successfully checked that values ​​in the database are true.

Here is the code: 

  if (! Reader.Read ()) {MessageBox.Show ("user can not be found!"); Reader.Close (); } And {int count = 0; While (reader.Read ()) {string user = (string) reader.GetString (0); String Name = (string) Reader. GestString (1); Int roll = (Int) Reader GetInt 32 (2); String Phone = (String) Reader. GestString (3); String address = (string) reader. Gastestring (4); String birthflow = (string) reader. Gesture string (5); Label1.Text = "" + Roll; Label2.Text = Name; Label 3 Text = postnatal; Label4.Text = "" + Phone; Label5.Text = Address; }}   
 But the problem is that whenever the loop is dropped.   
 
 Change  
  if (! Reader.Read ()) < / Code>  
 with  
  if (! Reader .hasRows)

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.
