O.P. Problem with class
I have this code:

FileSender.js
code:

    // Remove whitesc

    {
        string = string.substring(1);
    }
   
    while(string.charAt(string.length - 1) == ' ')

        string = string.substr(0, string.length - 1);

But the script debugger gives an error @ line 8:
code:
var prefs = new Prefs('prefs');


quote:
'Prefs' is undefined.


Why am I getting this error?

My Prefs class is defined in prefs.class.js..

RE: Problem with class
You are a code stealer. Prefs class is mine, you removed my license and put yours on it.

and you made the function assignment crappy!

Orignal found here
http://svn.thedt.net/cgi/viewcvs.cgi/*checkout*/s...-type=text%2Fplain


You shouldnt steal code , change it a bit then ask for help on it.

you sir are the lowest form of life.
