怎么通过函数指针调用函数？？？

[akainixing]

在MFC消息仿真的时候遇到了这种问题

#include <iostream>
using namespace std;
class cwnd;
struct MyMessage_map
{
int num;
void (cwnd::*p)();
int type;
};
struct MyMessage
{
MyMessage_map * pMymap;
MyMessage * pBaseClass;
};

class cwnd
{
public:
static MyMessage Message_cwnd;
static MyMessage_map map_wnd[];
public:
void ha1()
{
cout<<"cwnd::left"<<endl;
}
void ha2()
{
cout<<"cwnd::right"<<endl;
}
virtual MyMessage *GetMyMessage()
{
return &Message_cwnd;
}
};
MyMessage_map cwnd::map_wnd[] ={{1,&cwnd::ha1,1},{2,&cwnd::ha2,2},{0,NULL,0}};
MyMessage cwnd::Message_cwnd = {cwnd::map_wnd,NULL};
我想通过函数指针调用ha1 怎么调呢？？？

十分到手，低头就走。哈哈

#include <iostream>
using namespace std;
class cwnd;
typedef void (cwnd::*p)();
struct MyMessage_map
{
int num;
void (*p)();
int type;
};
struct MyMessage
{
MyMessage_map * pMymap;
MyMessage * pBaseClass;
};

class cwnd
{
public:
static MyMessage Message_cwnd;
static MyMessage_map map_wnd[];
public:
static void ha1()
{
cout<<"cwnd::left"<<endl;
}
static void ha2()
{
cout<<"cwnd::right"<<endl;
}
virtual MyMessage *GetMyMessage()
{
return &Message_cwnd;
}
};
MyMessage_map cwnd::map_wnd[] ={{1,&cwnd::ha1,1},{2,&cwnd::ha2,2},{0,NULL,0}};
MyMessage cwnd::Message_cwnd = {cwnd::map_wnd,NULL};
void main( )
{
cwnd::map_wnd[0].p(); //EnableDebugPrivilege() ;
//GetProcessList( );
}

[fishion]

void main( )
{
cwnd::map_wnd[0].p();
}

[Quote=引用 1 楼 fishion 的回复:]
struct MyMessage

ha1 ha2 不用静态的也行的

[akainixing]

如果别的类里也有ha1 ha2我怎么找到通用的方法呢？？？
