Loading DLL from a location in memory
As the question says, I want to load a DLL from a location in memory instead of a file, similarly to LoadLibrary(Ex).

What's are the naming conventions on COM libraries? When do I choose .ocx, .oca, .tlb, .olb?
EDIT: Since the original wording of my question caused much frowning I re-phrased it. Sorry about the confusion. Until now all my COM DLLs had the extension .dll, but I assume there are some rules about that. I know there are .ocx, .oca, .tlb and .olb files. I'm aware that these files all contain "COM stuff" but what exactly? What are...

Does GetSystemInfo give you the total number of virtual CPUs (i.e. hyper-threaded)?
GetSystemInfo will give you the number of physical CPUs / cores, but I would like to know the total number of virtual CPUs. I.e. on the new Nahelam chips, they have 4 cores, but appear as 8 cpus. If GetSystemInfo doesn't give this information, what API do I need (I've seen a function for getting number of logical processors, but it is V...

It returns the number of bytes written correctly, but the last 8 characters or so of the string are garbled. Here is the code f...

What does this hint mean? If I put Windows in...
