I've done this kind of application, but with Borland C++.

The short answer is "MSVC++ does not understand the GNAT debugging
info in the DLL". So what you are asking for (using the MSVC debugger
to step thru the Ada DLL) is not possible.

I used Ada.Text_IO.Put_Line in my DLL when I really needed to see what
was going on. Before that, I wrote really thorough unit tests for the
Ada code; Ada test drivers let me use the GNAT debugger.

You might try compiling the C++ code with the Gnu C++ compiler.
Depending on how much Microsoft-specific stuff you've got, you'll have
more or less success. That would give you uniform debug info. 

There ought to be a way to get the Gnu debugger to "attach" to the Ada
DLL, but I don't know how to do that, or if it is indeed possible.
