__event/__raise/__hook用法

#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./n", 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);
}

當程序執行到__raise source.MyEvent(123)時，程序就會跳到   void MyHandler(int nValue)
 執行printf_s("MyHandler1 was called with value %d./n", nValue)。簡單的用法！
