Managed lib into unmanaged project

[dp_mpi]

Hello Everybody,
I am developing a managed lib (using Microsoft Web Services) and I am
including it into a c++ project. The project doesn't use /clr optionk,
so when I include my linbrary's header file vs 2005 show me an error
saying I have to use /clr option. Doing this I have a incompatibility
with /EHs command line option (error D8016), but changing from EHs to
no exception handling I obtain a huge ammount of error from all other
previously working included libs.

Any suggestion is welcome.

Thank you in advance.

Daniele

You need to use /EHa, not disable exception handling.

You need to use /EHa, not disable exception handling.

With /EHa I have following
errors:

Does it exists a way in order to avoid those errors?

Thank you

solved.

There was an header calling "using namespace system" before a #include
<windows.h>.

Thank you.
