VC++2008关于【头文件】和【代码文件】和关联问题？

前面的帖子报404错误，麻烦版本删帖
这里重发一下吧:(

Catideology.h
C/C++ code

#ifndef Compiled
#define Compiled

public class Catideology
{
private:
    string m_sql;
    const string m_model = "abc";

public:
    void Catideology(string sql);
    int ParseSql();
};
#endif

Catideology.cpp
C/C++ code

#include "Catideology.h"
#include "stdafx.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

Catideology::Catideology(string sql)
{
    this->m_sql = sql;
}

编译之后，报很多错误，= =。。。求助。。
