Dear "The Skins Factory",
I have found an application to make Vista visual styles.
Ave's Vista Style Builder.
More Info about Vista Style Builder
VistaStyleBuilder comes with a simple GUI totally focused on editing MsStyles. Since VSB is specially for Vista, it has a Vista-look-and-feel.
Porting XP Visual Styles to Vista is made incredibly easy: VSB comes with an Import-XP-tool. Your imported Luna will even work in Aero-mode and get dropshadows for free!
STREAM image editing is fully supported and totally seamless; STREAM images are handled just like normal images. VSB will take care of everything, including resizing and layout out the stream efficiently.
The Preview window will show exactly how the margins will relate to resizing of an image.
VistaStyleBuilder gives you full control over your MsStyles file: you can remove or add new properties to every possible part. By adding new properties, new effects such as textglows in the taskbar can be achieved.
You can easily change complex parts with the help of StyleHacks. Vista Style Builder will come with a selection of StyleHacks made by the best MsStyle hacker, UK.Intel. [img]http://www.vistastylebuilder.com/screenshots/stylehacks.png[/img]
When you import a new image with a different size than the original, VistaStyleBuilder will prompt you what to do with the image.
Clicking the Test button will directly let your pc use the Visual Style you are developing. You also get an window which shows all common controls in their available states.
When you quit test mode or VSB, the Visual Style on your pc will be set back to normal.
