class CInsLibrary 
{
public:
 CInsLibrary(){;}
 virtual ~CInsLibrary(){;}
public:
 void Func(int i){;}
};

typedef void (CInsLibrary::*PFUNC)(int );

//main.cpp
 PFUNC pp = CInsLibrary::Func;                     //1)

 CInsLibrary* pLib = new CInsLibrary;
 PFUNC ppp = (pLib->Func);                           //2)

ASSERT(pp == ppp);                                        //caution!!

上面的代码在VC6中编译的很好，但是在VS2005中，
1)必须改为
PFUNC pp = &CInsLibrary::Func; 否则就是Compiler Error C3867
2）中的这种写法，VS2005已经不支持了。因为的确，指向成员函数的指针，更合理的写法是class::foo而不是object.foo
