Well, there is one cheap way of doing that is no one had ever thought of. hahhha. If you are using Windows XP, use your program to create a batch file in C:\Windows and make it run. In the batch file, use the commands
echo << [HKEY_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run] file.reg echo <<\yourfile.bat file.reg echo << . file.reg (not sure of this one, its supposed to make an empty line) regedit /s file.reg set /a datenum = 0 set /a datenum =+ 1 if datenum == 30 (or however many days the program should last) ( CD C:\Progra~1\YourProgram del yourprogram.exe ) exit
this will make the file run everytime the comptuer is started and increases a counter everytime that counts how many days the program has been in use and deletes the software after a specified number of days.
its a non-professional way, but it still works.
AnswerKeep in mind that the above batch file counts the number of times Windows starts up, not the number of days that has elapsed. 30 reboots might be the same as 2 days for some people! For other people 30 reboots could be up to 60 days. To be more effective you would need to check the actual date, which can be easily changed backward by the user to extend the amount of time they can use your program.A computer program is a set of rules that guides the computer to do a particular work, for which it is designed.
