What is the difference between Dreamweaver and Flash MX? I want to create a full flash site now. I don’t know which program is better
Dreamweaver: HTML editor.
Flash: well, Flash.
pom 
Succinctly put there.
Basically Flash is an animation program you can use to build cartoons, sites, banners, the works. It’s generally used to make multimedia based sites, with a high degree of user interaction.
Dreamweaver is as stated, an HTML editor, used to build web pages. You can embed a Flash movie into a page built in Dreamweaver.
