I suppose you need to insert some attribute telling ATL you
have a different version of your TLB, though I don't know
exactly what since I don't use attributed ATL due to bugs
in the generated code.

Hi

we have a ATL attributed project -a DLL library . This contains
a lot of ATL objects with IDispatch support.
We will public a next version of the library, also we change
version number in the library block from 1.0 to 2.0.

//MyLib.cpp
[ module (dll,name="MyLib",version="2.0", ....)]
class MyLibModule;

//ComObjA.h
[ object,dual, ....] __interface IA : IDispatch{ ... };

[ coclass, ....] class CComObjA : public IA
{
...
   BEGIN_COM_MAP(CComObjA)
       COM_INTERFACE_ENTRY(IA);
       COM_INTERFACE_ENTRY(IDispatch);
        ....
   END_COM_MAP()
};

After change the version number we can still compile all the sources but
support
for scripting clients goes broken ;-(((

After analyse the prb a have found that the compiler does make the prb by
insert line

public IDispatchImpl<CComObjA>

into merged code(ComObjA.mrg.h).
!! Default value for wMajor param is 1 !! - Injected code is bad.

Know anybody a bether workaround as insert

public IDispatchImpl<CComObjA, IID,LIBID ,2>

for each COM class ?
