Our company is in the process of acquiring the rights to a desktop application written in VB6. Putting aside converting the code to .Net. We are looking for a library/ActiveX control that would lock out unregistered users after a trial and require an annual subscription. I realize the best option may be implementing this product as a web application, but we are looking for a solution with the least amount of upfront development. Does anyone know of any 'software licensing' libraries for VB6 desktop applications? What are the best products out there?
You could go down several paths:-
(1) Use the Internet (and the Internet control in VB6) to register users and keep the list on the web server and then check after a certain date and disable the software.
(2) I develop USB-like software dongles (thumbdisk-size) if you're interested.

Take a look at our CryptoLicensing product. It supports everything you mentioned like activation, machine-locking and subscription licenses.
It is available for ActiveX
and for MFC (library form)
