__event/__raise/__hook用法

 MSDN的使用说明:

以下转自网络,用法说明简洁明了,原文链接:http://blog.csdn.net/dalek/article/details/5502624

#include <stdio.h>

//
class CSource 
{
public:
    __event void MyEvent(int nValue);
};

//
class CReceiver
{
public:
    void MyHandler(int nValue) 
    {
        printf_s("MyHandler1 was called with value %d. ", nValue);
    }

    //
    void hookEvent(CSource* pSource)
    {
        __hook(&CSource::MyEvent, pSource, &CReceiver::MyHandler);
    }
    void unhookEvent(CSource* pSource)
    {
        __unhook(&CSource::MyEvent, pSource, &CReceiver::MyHandler);
    }
};

//
int main() 
{
    CSource source;
    CReceiver receiver;
    //
    receiver.hookEvent(&source);
    __raise source.MyEvent(123);
    receiver.unhookEvent(&source);

}

当程序执行到__raise source.MyEvent(123)时,程序就会跳到   void MyHandler(int nValue) 
 执行printf_s("MyHandler1 was called with value %d./n", nValue)。简单的用法!
