VC2005使用hash_map,几行代码却一堆异常

VC2005使用hash_map,几行代码却一堆错误
声明一个hash_map，插入一个元素，编译得到一堆错:

C/C++ code

#include "stdafx.h"#include<algorithm>#include<hash_map>using namespace std;using namespace stdext;int main(void){    typedef pair<string,int> pi;    hash_map<string,int> hm;    hm.insert(pi("one",1));    return 0;}

编译错误如下: 我的代码错在哪里?

[解决办法]
#include <string>
[解决办法]
STRING类型无法识别吧
