SenCopy protects programs and components, for example ActiveX, given out for shareware purposes by displaying a copyright message window. The window typically informs the user about the following: who has developed the program / component, a limitation of liability, a forbade of distribution, that the program is a demo version until the appropriate key is entered. Besides informing the user the message window cripples the version, for the user has a little bit of effort to handle the window. Nevertheless you do not need two versions for one program or component, a full and a demo version, for a simple registration mechanism makes the demo version a full registered one. Both the window and the form and frequency of appearance can be customized by the attributes of this component. The key for a single or a group of computers is provided by a registry file sent to the user by mail for example. A special program named 'KeyGemo' performs the task of creating and storing these keys that are special for every customer and every kind of program.
