I'm implementing the SNHookClass to allow the user enter the license for my plugin. What is the
c4dsn String passed to ~:SNCheck(); when working on a MultiLicense environment?I'm asking because
- I can't test it (don't have a MultiLicense environment lying around..)
- GeGetSerialInfo() can be called for either retrieving the MutltiLicense or the
generous license.
Is it the 11 digits only and I have to manually check for a MultiLicense, or will be it be the 18
characters long MultiLicense string (12345678912-ABCDEF) ?Thank you,

Giblet has a very informative post here that outlines the required format of the serial number for the Maxon License Server for plugin registration. The post is: "R11 License Server & SNHookClass"

Indeed a very informative thread.And there is a 5 part tutorial about licensing plugins at the "C4D Programming Blog" that also might be interesting for you to read.
Even though there is no extra information about a License Server implementation to find.Thank you Robert for your whole licensing source code(s).
I already have a working solution for myself but I think I'll take a look at yours too and maybe could get some ideas for improvements of my own.
E.G. I still wasn't able to implement a time limited demo mode that really would work as expected. -

Great to have another open piece of source code for C4D !
Thank you! Lets lock what new I can learn from it.May be we could start GitHub for all the code?

+ 1 !!!!!
I already have some C4D related stuff on my GitHub profile: https://github.com/NiklasRosenstein
