Is there any problem when calling a function in a dll from a ATL
method?

No. You do it all the time - remember that every Win32 API function is a
function from a DLL.

When I comment out the line c = AbrirConfiguracao(....), the ATL
compiles fine. But when I uncomment this line I get the error:

CRS2ATL error PRJ0019: A tool returned an error code from "Register
DLL".

Your DLL now depends on some other DLL that implements
AbrirConfiguracao. That other DLL must be in the path for your DLL to be
able to load successfully. It appears that this is not the case. As a
result, self-registration step at the end of the build fails to load
your DLL, because it fails to find the other DLL you depend on.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
