Re: Multiple inheritance

I have hierarchy, that contains one base interface class -
IConnection,
and two derived interfaces: IClientConnection and IServerConnection

=================

class IConnection
{
public:
   virtual void Send() = 0;
};

class IClientConnection : public virtual IConnection
{
public:
   virtual void Connect() = 0;
};

class IServerConnection : public virtual IConnection
{
public:
   virtual void Accept() = 0;
};

=================

I also have a realization for base interface

=================

class Connection : public virtual IConnection
{
public:
   virtual void Send()
   {
   //...
   };
};

=================

For two other interfaces I want to use existing realization of base
interface.

=================

class ServerConnection : public IServerConnection,
                        piblic Connection
{
public:
   virtual void Accept();
};

=================

I inherit Connection, because I don't want to duplicate the code from
Connection::Send();

When I compile this code with Microsoft compiler, I get following
errors:
warning C4250: 'ClientConnection' : inherits
'Connection::Connection::Send' via dominance.
Is there a better way of doing this? How can I avoid multiple
inheritance and code duplication?
I really like an idea of such inheritance. Why is it bad?

From the source code you supply, I think you've got the hang of this
