If you are forced to use native C++, you have to use COM Interop, indeed.
Here is how you can do this:

tlbExp myVBdotNETLib.dll

generates a .tlb file

in your C++ code:
#import "myVBdotNETLib.tlb"

However if you can use the managed features of C++, it is much easier, since
you just need to reference the managed dll in order to use it's types from
managed code. You can import this either via
#using "myVBdoNETLib.dll"
or via the compiler switch /FU, use VS.NET project settings for that.

Native C++ is plain old C++ programs where you do not use any of the
Managed .Net classes or compile with the /clr option.
