I have small application and would like to protect it. It may be sold to an individual or to a company in which case UserName and DomainName may be a good controlling parameter.
In case like this, I could store its string (UserName or DomainName) in tag property of a control to verify its validity in form load event.
I also want to mail it to various customers for trial. How can I can handle this part.
Any comment in either of above questions is greatly appreciated.
