Can u pls. help me out to implement function overloading with in a same interface using IDL VC6.0

Eg:
interface ITest : IUnknown
{
[id(1),helpstring("method Method1")] HRESULT Method1(void);
[id(2),helpstring("method Method1")] HRESULT Method1([in] int value);
}

this one gives a compiler error "redefnition". Why ??

Best Regards
