    I want to add a serial number registration to my plugin.  Do I create an completely new function to do this or do I do this in Init()?

    I have never done this so I am guessing that I create a dialog that only shows up if the product has not been registered?  The dialog will be looking for a serial number based on SerialInfo and my own  algorithm.

    Then when the user enters the info, I somehow store it to a file on their computer somewhere and when the plugin loads, it should look for the existance of that file?

    Is that about what I will need to do?

    It's a pity that the SDK doesn't contain a standardised method of doing this. As it is, when I was working out how to do this, it seemed that there were as many methods of writing these routines as there are plugin authors! The result is that I don't really know if the method I used is valid (i.e. secure), just that it works. This is how I did it:

    1. I have a global boolean indicating if the plugin is registered. When the plugin is called by the user, that boolean is checked in the Execute() function. The first time the plugin is called in any session of using C4D, the boolean will be false, so I do a serial number check.

    2. To do that, I attempt to load the serial using ReadPluginInfo(), and if I can read someting, I run a serial check on what has been loaded (you need to provide your own algorithm for that).

    3. If the serial is valid, the global boolean is set to true, so from then on whenever the user calls the plugin, Execute() checks the boolean and doesn't need to check the serial again.

    4. If the serial is bad, or ReadPluginInfo() couldn't read anything, I ask the user to enter a serial, and if they enter a valid one that is saved to disk using WritePluginInfo(). From then on, it's registered and the user won't have to do that again.

    Complications arise if you provide a demo - you have to decide how that will work. It seems to me that there are three choices: a limited functionality demo, which is made fully functional when a valid serial is entered; a time-limited fully-functional demo, which is the option I favoured but then you have the bother of saving the initial installation date and checking that if the serial check is not valid; or letting the demo version only work in the C4D demo, which I personally dislike as it means having the demo installated alongside my registered C4D installation.

    Hope that helps a little.

    Actually there is, the SDK provides the Serial number library. Please check the SDK documentation for the SNHookClass class.

    In the end it is of course up to the plugin developers how they handle the serialisation of their plugins.

    cheers,

    Yes. Please check the serial_hook.cpp file in the SDK examples.

    Serial hook registration is in C4DPL_INIT_SYS, see main.cpp.

    There is also another plugin serialization SDK example to create your own serial dialog, check serial.cpp.

    The difference is SNHookClass serialization has no own dialog but uses the CINEMA 4D 'Personalize' dialog and simplyfies reading/writing of the serial number.

    cheers,
    Matthias

    Hi Matthias,

    Yes, I was aware of that class but many plugin writers seem to do things in other ways, for reasons that aren't clear to me. Is this now the Maxon 'recommended' way of handling serials for plugins? I somehow got the impression it was only intended for Maxon's own modules, although I know a few authors have used it as well.

    There is no 'recommended' way. It's really up to you. Currently there are two serialization methods supported directly through the SDK. One is to use the SNHookClass and the other to use the WritePluginInfo/ReadPluginInfo WriteRegInfo/ReadRegInfo function to write/read private data for your plugin serialization.

    cheers,
    Matthias

    My question is, what am I supposed to do to prompt the user to put in their serial number, and where do I determine the algorithm for the serial number.    When I finally do determine that,  I will of course not post it on this forum .  LOL

    Also, shouldn't I see another serial field when I go to the personalize dialog box with the code I have?

    Once again I am new to this whole part of it so any help you can offer would be greatly appreciated.

    Did you call RegisterPlanetXSerial() during C4DPL_INIT_SYS to register the plugin with Cinema?
