When you download StForm, you will obtain a folder with all the necessary files to modify the transparency of the application windows. You will be able to see the transparency level as well as the control colors. What's more, StForm includes a demo of the application with the effects already applied, with which you will be able to check how StForm works.
If you are creating your own application and you want to give the interface a special touch, StForm makes it possible for you to give the windows a transparent effect, without having to have any great knowledge of programing.
Looking after an application's interface makes the users more predisposed towards it and thus makes it more probable for them to get more from the tool. StForm will make this task a lot easier for you.
