Deleting existing databases

What's the proper way to delete an existing database through native c++ code?

When I try DeleteFile(filename), I get an error about another process using that file. I hadn't created a connection to that file in my own program, so I assume that lock is from the sql engine.

Thanks folks!
does anyone have any insight in this matter?
