I am about ready to try to sell my software (vb.net, winforms) from a website or a CD. I would like to provide potential customers a 30-day trial copy, after which the software would cease to work until they purchased a license key from me and pay for it via PayPal.
I don't have a clue how to go about this, or if its really the best thing to do. Its just what I have seen other software vendors do and I would like to do it also.
Suggestions, advice, appreciated.
Thanks in advance.
