webservice and MFC

[cipher]

I'm trying to use an MFC extension dll in my C++ ASP.NET Web Service
project. I have changed my project settings to specify using MFC as a
shared dll. However, when I try to compile, I get the following error on
one of the extension dll header files:

error C2491: 'CGisPtrArray<TYPE>::__ctor' : definition of dllimport function
not allowed

I get the same error for every method declared in this template class. The
template class is entirely defined and implemented in the header file. I
have been unable to get past this error. Does .NET just make it impossible
to reuse completely functional code from VC++ 6? Help is appreciated.
Thanks

This message seems to show that you are using a unmanaged definition where a
managed definition is expected.
Do you have an error on a MFC header file or on your header file ?
Do you specificy "__nogc" on your class to exclude managed extension ?
My guess is you must think to have an unmanaged layer in your project.

The error is occurs on one of the MFC extension dll header files. This is a
fully functional MFC extension dll, I shouldn't have to modify it to reuse
it and in many cases this isn't an option. (e.g. 3rd party dll)

The error is saying that you are trying to provide an implementation for
a method that was first defined for import from a linked library
(dllimport).

Can you take a look at the header and check why the compiler thinks this
is a dll import class?

Also, you cannot specialize a template with a managed type if I recall
correctly.
