CMap and its key types
-
Hi everybody, here's a newbie one for y'all: I was hoping that I'd be able to create an instance of CMap using very simplistic keys with something like:
CMap< int, int&, CMyClass, CMyClass& > m_myMap;But I get a "'operator =' function is unavailable" error from the compiler. Is this because I have to use keys that are objects of a class, or what?

operator =within CMyClass.CMyClass& operator =(const CMyClass& right)
{
// Do the copy of data
// e.g. m_Data = right.m_Data;return *this;
}Ant. I'm hard, yet soft.
I'm coloured, yet clear.
I'm fruity and sweet.
I'm jelly, what am I? Muse on it further, I shall return! - David Walliams (Little Britain) -

I thought that the "= not defined" thing was about CMap member functions not being able to compare keys rather than the objects...? Anyway, thanks I'll try that! ------------------------------------ Håkan Olsson, M. Sc.

If it was complaining about a compare method it would be "==" not "=". Mike
