DLL in memory

[David Crow]

Are you wanting to know the difference between implicit and explicit linking?

LoadLibrary requires the DLL to be on the disk. So you will need to write the contents of the memory to a disk file and then call LoadLibrary on it.

Yes. you can load one DLL into System Memory.

I think I don't understand. The problem is that I want to avoid LoadLibrary().

Then you must link implicitly.

I think I don't know the difference between implicit and explicit. I think I need an example.

Firstly, it's far from clear what you mean by "loaded into a memory table". It sounds like your want to re-implement the loader. In general I'm not sure if this is possible from user mode. There's a lot more to getting a module into memory in a executable state then simply having the module in memory: relocating, recursively loading all dependent modules, resolving imports (building the Import Address Table, for example), etc... Even if you did do all these things (and more that I've forgotten) it's far from clear that "unusual" things, for example code that enumerated all loaded modules, would work.
