Question

I created a vb.net dll called “WSdll.dll”.
I compiled it, created a type library (tlb), and registered it globally(gacutil)..
It includes a file called wsutils.vb, which includes a namespace called “wsutils”.
In the namespace, there’s an interface (with attribute) called “IWSconnection”, and a class called “WSconnection”.
The interface and class are public, as are all methods and properties.

I then tried to implement it in an unmanaged c++ project.

I imported it:
#import “..\WSdll\WSdll\bin\Debug\WSdll.tlb” \
raw_interfaces_only, \
named_guids, \
no_namespace

Then tried to create an instance:
CComPtr< IWSconnection > pIWSconnection;
pIWSconnection.CoCreateInstance( __uuidof( wsutils::WSconnection ) );

I am getting 2 errors a)wsutils is not a class or namespace name b)wsconnection undeclared identifier

What other steps do i have to do to get the dll working here?

TIA

You put no_namespace in the #import line – so your object is not in the wsutils namespace, it’s in the global namespace. Remove either the no_namespace from the #import line, or the wsutils:: from the object creation line.
