VB Forum / COM / October 2006Exe to expire after stipulated time period
Hai, I developed an data entry application. I packed my exe and i am suppose to provide it to my vendors. I want to ensure my software not to be misused. So i want to write code in such a way so that the exe should not work after the time period. I should have the control of the exe.Is there is any way for my problem to be solved? Please assist me. > Hai, > [quoted text clipped - 4 lines] > the exe.Is there is any way for my problem to be solved? Please assist > me. There are so many ways to do this... none are perfect. Here's one way... Advanced Commercial Strength Wrapper http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=49120&lngWId=1  SignatureKen Halter - Please keep all discussions in the groups.. In Loving Memory - http://www.vbsight.com/Remembrance.htm One thing you can do is, if your data entry software directly operates on time sensitive data, i.e. records contain date and they are necessary for the operation of software then you can put some constrains on it. e.g. you can teach your software not to accept any entry after a specific date, where the date to be compared is the date of record and not the system date. This is something which works in almost all situation because comparing your application date with the system date doesn't help because anyone can easily bypass it. One more way is to protect it with the number of run constraint and not the date. It is independent of the current system and hence can work good for you. You should do few more things, i.e. fasten your application with the machine using HDD serial number or something which can uniqely identify the machine. MAC address can too do. One more thing is protect your setup with password which is dynemically generated. If you don't know how to do these things, you can ask me for the actual code to get things done. Hai, Please provide me the actual code and do the favour. > One thing you can do is, if your data entry software directly > operates on time sensitive data, i.e. records contain date and they are [quoted text clipped - 15 lines] > generated.
