Art and Brian are re enable this ability in the latest versions of Mach so I can included an example for you.
As soon as they make that update I will post the demo file here.
When it is ready you will have 2 options to load screens.
---------To create "Wizards" or load external data in Flash--------
-Option 1
Mach's conventional screen ".set" using SWF
Benefits are: you can load flash "SWF" wizards using a Mach's conventional screen ".set"
1. Create a Folder in your : C:\Mach3\Addons\
2. Start Mach and load wizard.
-Option 2
Flash screen "Load External data"
Using: "Load Movie" (which is a way to load external swf's,data,text file,picture,movies)
Benefits are you can load many different file types (exp: swf, .set, xml, flv, mov, bmp, png, jpg, css, html, php...) .
You can also load as many as you would like at once, and as well as display them in any location and size you wish.
This is very hard to explain without a demo file...will have one as soon as they are done.
