c++ - Loading DLL from a location in memory

Question

As the question says, I want to load a DLL from a location in memory instead of a file, similarly to LoadLibrary(Ex). I'm no expert in WinAPI, so googled a little and found this article together with MemoryModule library that pretty much meets my needs.

On the other hand the info there is quite old and the library hasn't been updated for a while too. So I wanted to know if there are different, newer and better ways to do it. Also if somebody has used the library mentioned in the article, could they provide insight on what I might be facing when using it?

Just for the curious ones, I'm exploring the concept of encrypting some plug-ins for applications without storing the decrypted version on disk.

Implementing your own DLL loader can get really hairy really fast. Reading this article it's easy to miss what kind of crazy edge cases you can get yourself into. I strongly recommend against it.
Just for a taste - consider you can't use any conventional debugging tools for the code in the DLL you're loading since the code you're executing is not listed in the region of any DLL known by the OS.
Another serious issue is dealing with DEP in windows.
