Exception 0xc0020001 in mixed mode (C++/C#) application

[suhas shingade]

Hi

I have a MFC application that needed database capability. So instead of writing this in C++ I created a C# based library and wrote a managed C++ wrapper to access it in native code. The application works fine but during exit I get an exception "0xc0020001 at location XXXX". I googled the exception and got a bunch of hits, which, to summarize, hinted that this exception may occur when unmanaged code is trying to access managed code AFTER the CLR has shutdown. Most of the google results were old and were for VS 2005. I am using VS2008 SP1. Another thing is that this application has been migrated from VS 6.0 and thus the project settings are not same as a brand new project created using VS 2008 (I don't know if that makes a difference).

I cannot debug this issue from the IDE because this is aa application that controls an instrument and currently I cannot connect my dev workstation to the instrument.

Thanks
Suhas

Have you considered using an Access database? That way you only need to SELECT from your MFC code.

Checkout ODBC.

Yes. That is my backup plan if this does not get resolved soon.
