Creating 'commercial', trial/registered versions of a B4PPC program.... I know that this is a subject that has been raised a number of times before, but as far as I can see, there have been no simple but effective solutions proposed on the forums. I would therefore like to bring up another aspect of it. I have been looking around and found a number of commercial product that are aimed at the VB, C and .NET realms of PDAs & Devices. I was wondering if it would be possible to use one of these with a B4PPC program. They all have examples of how to add the necessary code to an eVB, eVC or .NET program and obviously this would not work 'as-is' with B4PPC. But perhaps the various function calls, etc could be converted to a form that B4PPC would accept? Perhaps even a simple DLL could be used to interpret between the program and the registration system? As is obvious from this, I have no idea really what could (or could not) be done but I would at least allow me to close off a line of inquiry if someone could categorically state it would not work! FYI, I have been looking at the Locker system (Locker CE - Pocket PC Software Security), Eziriz (www.EZIRIZ.com) and Net Licensing (.Net Licensing Pro - Home) as possible contenders. I look forward to your comments David.
