This is a tough one, I want to overload the arithmetic operators in a pur virtual abstract class.:confused: The pur abstract class defines the basic 'Interface' from there I have a base parent class that will be the default implementation and several parallel child classes. e.g.

virtual IClass operator+(IClass& RHS) = 0;

Then I can implement it in BaseClass. Problem: Can not instantiate abstract class. changing it to

virtual IClass& operator+(IClass& RHS) = 0;

means that the statement is valid BUT it can't work (or can it?) this returns a reference to IClass which isn't what we want in addition, we want to return a value not a reference. So how can I do this whithou getting in to memory leaks and such. For addition we want to be able to do result = a + b + c + d, etc. This is pure old (not C++11) C++ I'm working in today.

Thanks, the article does not apply, but the forum looks interesting.

I have an application that uses C# as the script language. The C# is compiled on the fly from within the application and executed. I would like to be able to allow the user to debug their C# code from within my application. I read an article somewhere on this a year or two ago and I can't fint it any more and I can't remember where. I remember that it was just a slight variation on the standard CodeDom Compile-Load sequence. Searched MSDN and several other sites, but no luck. Anyone know the answer?
