List.Sort(compare_function) - term does not evaluate to a function taking 2 arguments

[Shaitan00]

I am trying to customize my sorting of a LIST using a compare_function, but for some odd reason it keeps giving me the following error:

error C2064: term does not evaluate to a function taking 2 arguments

 

Specifically, I have list created within class B which needs to be sorted, the list contains elements of type A* as shown below:

 

Class B code:

B::B()

{

list<A*> AList;



AList.push_back(new A(ID_1, CODE_1));

AList.push_back(new A(ID_2, CODE_2));



AtList.sort(&B::compareID);

}



bool B::compareID(A* first, A* second)

{

return true;	// test for now

}

[/Code]

 

Just for completness the following is the code for Class A:

[Code]
Class A
{
long ID;
string sCode;
A(_ID, _sCode) : ID(_ID), sCode(_sCode) {};
}
[/Code]

 

So, pretty much I just want to sort AList by ID, but for some odd reason this generates:

error C2064: term does not evaluate to a function taking 2 arguments

 

Also, in the future I am going to want to create a compareCode() function to also compare by code ... thought if one way works so will the other ...

 

Any clues, hints, or help would be greatly appreciated.

Thanks,

Maybe B::CompareID should be static?
