If I understand correctly, the only way to let flash run code dynamically is through loading a SWF , the path of which could be dynamic like based on day or user input ? regards Devdatta --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Tracy > > > > ________________________________ > > From: [email protected] [mailto:[EMAIL PROTECTED] On > Behalf Of Josh McDonald > Sent: Thursday, June 19, 2008 7:58 PM > To: [email protected] > Subject: Re: [flexcoders] Re: string to actual actionscript code? > > > > I'm fairly certain that while you could run code with eval() it wouldn't > have any side effects.
