CNyfDb's Constructor

There're two methods to construct an object of the CNyfDb class from either a position number or a .nyf file path;

1. Constructing a CNyfDb object from a position number of a .nyf database opened and listed on the database Tab control in the main window.

   • Prototype: CNyfDb(iDbPos);
   • Parameters:
     1. iDbPos, a position number (0-based) of a .nyf database opened and listed on the database Tab control in the main window. Defaults to (-1), which stands for the currently working database.
   • Return Value: an object of the CNyfDb class.
   • Example:

     try{
     var nyf=new CNyfDb(-1); //-1: for the current one;
     alert(nyf.getDbFile());
     }catch(e){
     alert(e);
     }
     

2. Constructing a CNyfDb object with path to a .nyf database file.

   • Prototype: CNyfDb(sDbPath, bReadonly);
   • Parameters:
     1. sDbPath, path to a .nyf database file.
     2. bReadonly, determines if or not to open the database as Readonly.
   • Return Value: an object of the CNyfDb class.
   • Example:

     try{
     var nyf=new CNyfDb('/home/username/test/1.nyf', true, 0);
     alert(nyf.getDbFile());
     }catch(e){
     alert(e);
     }
