I have a weird exception happening when calling the new operator. I'm
not sure if this is the intended reaction to the situation or is

default namespace prepened to the name of the bitmap, and that the default
namespace is the assembly name. It then mentions that one can ...

I have a method in a C# assembly like this:
public virtual void RefMeth(ref bool hi) {}
And I want to override it with a VS.Net 2003 Managed C++ method like this:
void RefMeth(bool __gc& hi)

I like to know if is it possible to disable/reenable /WX (treat warning
