null reference exception in VB calling C++ cout

[Sheri]

I have a VB .NET program invoking C++ code through a dll. Calling cout
generates "Unhandled Exception: System.NullRefe renceException: Object
reference not set to an instance of an object". A line in ostream header
file is causing this error.

I used vbc to build my VB dll. Am I just missing a dll to link in iostream
functions?

#include <iostream>
cout << __FUNCTION__ << " exiting prematurely due to errors\n";

I am new to using VB and .NET. Thank you for any ideas here - I've looked
everywhere for an answer!

RE: null reference exception in VB calling C++ cout

This was solved by a co-worker:

When we build the C++ dll with /noentry, static variables do not get
initialized, causing problems in std file i/o functions. So, we added
special initializer code to do this, and made some other changes to our link.
See msdn page on /noentry for details.
