[vlc-devel] ActiveX: failed to load DLL

[Damien Fouilleul]

libvlc.dll is linked at build time, which means that LoadLibrary() is  
performed automatically by windows when axvlc.dll loads.

regarding your problem, they are 2 issues you need to consider when  
using LoadLibrary(TEXT("ABC.dll"))

- ABC.dll cannot be found because it is not reachable from PATH or  
isn't in the same directory as loader (.i.e AXVLC.DLL)
- ABC.dll has external dependencies (i.e it needs to load DLLs itself)  
which cannot be found

you will need to examine the error from GetLastError() to find out  
what happenned.
