Is this a specific C++ behavior ? or my compiler (msvc7) ? Is there a good way to write "titi.Add(1)". I know i can wrap "Add" in Titi class and call Add Parent but if i can avoid this... Thanks.

Is this a specific C++ behavior ? Yes. Quote: or my compiler (msvc7) ? No. Your compiler is correct. The Add function in Titi hides the Add function in Toto Quote: Is there a good way to write "titi.Add(1)". struct Titi : public Toto { using Toto::Add; void Add( int x, int y ); }; Quote: I know i can wrap "Add" in Titi class and call Add Parent but if i can avoid this...

Hello, Overloading works only in the same scope.. The methods are not overloded if they are in different scope. The compiler would issue an error, as it cannot find the other Add method.
