Okay, I have to ask it here, because I don't know how to ask on SO so I don't get banned.
I have a user mode driver (a dll and an inf file). How do I load it (aka call DllMain)? Do I have to install it first so it shows up in device manager? How do I load it then? No, there is no physical hardware involved, it's all software.
I've been searching for an answer for days, but when to comes to driver development, I'm such a noob that I don't even know what to look for.

    It is supposed to be a display driver that creates virtual displays on the PC. I found a demo of this on github (google "kfroe iddcx", 1st result) but I don't know how to get it to work without any actual hardware.

    I would really appreciate some help.

    I wouldn't think you can get banned from SO by asking such a question

    @ananaszjoe I have recieved downvotes or got my question closed in the past because it was "too broad". For me, asking on SO is a last resort, after at least 3 days of trying to look for an answer. And most of the time I don't even know what the correct question is that would get the right answer.

    >>> I don't even know what the correct question is that would get the right answer

    The key lies right there. Until you have the question, you can't have the answer to it.

    I'm guessing you've seen this? https://docs.microsoft.com/en-us/...

    Probably this a better starting point https://docs.microsoft.com/en-us/...

    https://docs.microsoft.com/en-us/... and possibly this? Might have to sift through the hardware driver stuff, not entirely sure where you'd start since I'm not too experienced

    @beegC0de Yes, I've seen it and I've been struggling to get a VM ready for debugging ever since. I can't even get a simple "Hello World" driver running xD. This will bee a bumpy ride.

    Thanks for the links though :D

    I don't think you need to call DllMain do you? Although I'm not really sure what constitutes a driver, maybe you need one of those other hooks

    @beegC0de Based on the MSDN documentatio about IddCx, I only need to call a couple methods to add a new virtual display. Since I'm not working with any hardware, maybe I don't even need a driver at all. Maybe those winapi methods can be called from a simple vc++ exe application. That would be the best case, I'll give it a try when I get home.
