Question

BETA Function in VB.NET

Asked by: cjinsocal581

I need to create a function that when the software is ran, it starts a 30 day clock. Once that 30 day clock is met, the software will no longer run. even better would be if it could delete itself. (Far fetched I know) but I need to protect the software in the best methods.

Any ideas?

you can write the date to the registry and then check in the procedure the date difference. If it is more than 30 days than skip the procedure

 

by: TheLearnedOnePosted on 2005-02-17 at 08:50:31ID: 13336514

Until, I figure out which registry key it is, with my installation monitoring program, and then change the appropriate key value.

BTW, Iouri, congrats on your first million.

I have never written to the registry using VB.NET, is it much different that VB6?

 

by: iboutchkinePosted on 2005-02-17 at 08:54:33ID: 13336571

Thank you Bob

I think that an appropriate option would be version managed dll and GAC instead of computer registry.You need a dll in Your project of time limited version

 

by: cjinsocal581Posted on 2005-02-17 at 08:55:21ID: 13336586

sugestiong on what dll?

 

by: oleggoldPosted on 2005-02-17 at 08:57:06ID: 13336614

Any dll ,just make some changes to the AssemblyInfo.vb file

 

by: oleggoldPosted on 2005-02-17 at 09:05:11ID: 13336720

By this way ,You can use an Unmanaged code and are not required to have System.Security.Permissions.RegistryPermission

That is a little over my head at this point in my development.

Is there any sample apps doing this that you know of?

Or third party apps that handle this?
