//---------------------------------------------------------------------------

#pragma hdrstop
#include<iostream.h>

#pragma argsused
class A

};

class B : public A
{

};

int main(int argc, char* argv[])
{
B b;

if(typeid(b)==typeid(B))
cout<<"OK"<<endl;

if(typeid(b)==typeid(A))
cout<<"ERROR"<<endl;
cin.get();
return 0;
}
//---------------------------------------------------------------------------

[Hot_Forever]

class A
{
};

class B
{
};
#include <iostream>
#include <typeinfo>
using namespace std;
int main(int argc, char* argv[])
{
B b;
if(typeid(b)==typeid(B))
cout<<"b is a class B object"<<endl;
else cout<<"b is not a class A object"<<endl;
if(typeid(b)==typeid(A))
cout<<"b is a class A object"<<endl;
else cout<<"b is not a class A object"<<endl;
cin.get();
return 0;
}

楼主是想要RTTI吧.

typeid 不是宏

[jhyu]

typeid 是函数
我把它同mfc里面用于atti的宏混淆了，汗~~~~~~~
另外c++提供了typeinfo类可以使用
