I get some weird error message saying:

E:\vc++\Private\StarDist\CFlexPoint.h(53) : error C2662: 'Y' : cannot convert 'this' pointer from 'const class CFlexPoint' to 'class CFlexPoint &'

when I try to overload the < operator..

it sounds like you declated operator < to be a const function, which it usually is, by including a "const" after the function's parameters, like the final "const" in

bool SomeClass::operator <(const SomeClass &Rht) const;

That is fine, in fact usually prefereable, but it means that the object that the function is invoked for must be treated as a constant object.  If you try to change the object, or try to call a non-constant member function (one that doesn't hae this "const" at the end), then you will get this error.

How to go about fixing the problem depends on details you haven't provided.
