![]() SystemInfo class is for getting system information. It's better you choose your own key for encryption. I mean some obscure path.īoth files will be encrypted using Triple DES algorithm. You can save HideFile in, for example, C:\Windows\system32\tmtst.dfg. It will contain the serial that the user entered ( HideFile). The second file will be used if the user registers the software. It's not a bad idea to save this file in application startup directory This file must be in a secure place, and the user must not find it ( RegFile). The first file is used to save computer information and remaining days of the trial period. There are two files to work with in this class. To make a password, you must have your own identifier. The password will be produced by changing the Computer ID. Trial Maker uses management objects to get hardware information. In the source, Computer ID = "BaseString" That's because if you have used Trial Maker to make a trial for more than one application, each application will have it's own Computer ID. To make a Computer ID, you must indicate the name of your application. When you give the password to a customer, his password won't change until he changes his hardware. You can choose what hardware items you want to use to make the computer ID. Processor ID, main board manufacturer, VGA name, hard disk serial number, etc. The computer ID is a 25 character string that came from hardware information. If the trial period is finished, reinstalling the application won't let user run it. After entering the password, the application always runs as the full version. Then you will use the Serial Maker to make a serial key (password). If someone wants to buy your application, he must call you and read his computer ID. You can do this kind of task with this library. For example, you need your application to only run for 30 days, or the user can only run your application 200 times. It's very common to want a trial version of your application. Download FilterTextBox Control files - 19 Kb.Download SerialBox Control files - 34 Kb. ![]()
