If you are trying to open a web page (html, php, etc) inside a movieclip in Flash, it cannot be done. The link you showed discusses loading a Flash movie into a movieclip, which is very different and can be done.
well it's not really a webpage i was just give an example. I have a menu on top and i want went i click an link on the menu it open in the movie clip.
so bascially i have the menu and i want to load the content below it so if a movie clip is not the correct way can you please let me now how i would accomplish this.
that how alot of website is so i wouldn't think it's hard.
You may be misunderstanding what you see in those web sites.
One way of using Flash... you can create a Flash menu and have that placed in an html page as the navigation for the site, but each of the pages that it pulls up are separate html pages with the same menu being reloaded into each.
Another way is to have a full flash site. This is where the pages are built into the Flash file, they are not linked html pages, so each buton either goes to a different section of the timeline or manages the display of sectional movieclips. Using this apporach, you can also create separate Flash files that you can load as different sections, but they are still swf movie files and not web (html) pages... this is what that link you showed talks about.
Thanks the first option is what i want to do, I have a flash menu and it's in the html. I create i figure i could of done something like a frame but i guess not.
I will just create a frame and put the menu in.
Thanks for all your help.
