The only option here is to add the DLL file as a resource to your 
executable.  At application start, extract the resource and write out to 
a temporary file in the application directory.  Load the DLL via 
LoadLibrary, get the function address via GetProcAddress.  At 
application end, unload the library and delete the temporary file.

Note that this is not allowed on Windows XP if your application is in 
the Program Files directory.  Applications are not allowed or should not 
write to their application directory due to security restrictions.
