Re: LibraryLoader loads wrong DLL

Hi,

Thanks for the link. I have tried using my interface in a C-program,
and there the loading is correct, so why is the loading different
there from what is done in ctypes? How are the search directories set
in ctypes?

I'll try the trick you propose and see if its a workaround

Thanks,
Thor Andreas

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
