[bltfr]

hi,
I have a native C++ dll and i want to call it from an atl dll.I have included the necessary header files and libraries but it doesn't work. Could you tell me the steps to do this operation?

You will need to derive your class from and atl base class and override the intterface you wish to support. You make your dll call in

the override using your own code.
