c++播放Flash文件 - c++编程基础

最近由于需要在程序中使用Flash播放，所以学习了下如何播放Flash，这里使用atl库中的CAxWindow来处理我们要播放的Flash！由于Flash的很多接口我们都不知道，所以可以
这篇文章中介绍了如何导出Flash的接口，这篇文章主要介绍一下，Flash的时间的通知，以及如何利用windows的API，进行两个Flash的混合播放！新建一个默认的 win32窗口程序，然后加入后面的头文件，这里主要是加入atl库文件，以及adobe公司的flash的ocx控件。[cpp]
PRE class=cpp name="code">#include
extern CComModule _Module;
#include
#include
#include "flash32_11_7_700_224.tlh"
#include
using namespace std;
using namespace ShockwaveFlashObjects;

CComModule _Module;

然后我们建立个Flash事件的处理类:

class FlashSink : public ShockwaveFlashObjects::_IShockwaveFlashEvents    
 
 {    
 
 public:     
 
     LPCONNECTIONPOINT       m_ConnectionPoint;      
 
     DWORD                   m_dwCookie;    
 
     int                     m_nRefCount; 
 
  
 
 public:    
 
     FlashSink()    
 
     {           
 
         m_dwCookie = 0;    
 
         m_ConnectionPoint = NULL;    
 
         m_nRefCount = 0;    
 
     }    
 
  
 
     virtual ~FlashSink()    
 
     {    
 
  
 
     }    
 
  
 
     HRESULT Init(CComPtr ptrFlash)    
 
     {    
 
         HRESULT aResult = NOERROR;    
 
         LPCONNECTIONPOINTCONTAINER aConnectionPoint = NULL;    
 
         if ((ptrFlash->QueryInterface(IID_IConnectionPointContainer, (void**) &aConnectionPoint) == S_OK) &&    
 
             (aConnectionPoint->FindConnectionPoint(__uuidof(ShockwaveFlashObjects::_IShockwaveFlashEvents), &m_ConnectionPoint) == S_OK))                
 
         {    
 
             IDispatch* aDispatch = NULL;    
 
             QueryInterface(__uuidof(IDispatch), (void**) &aDispatch);    
 
             if (aDispatch != NULL)    
 
             {    
 
                 aResult = m_ConnectionPoint->Advise((LPUNKNOWN)aDispatch, &m_dwCookie);    
 
                 aDispatch->Release();    
 
             }    
 
         }    
 
  
 
         if (aConnectionPoint != NULL)     
 
             aConnectionPoint->Release();    
 
  
 
         return aResult;    
 
     }    
 





  
 
     HRESULT Shutdown()    
 
     {    
 
         HRESULT aResult = S_OK;    
 
  
 
         if (m_ConnectionPoint)    
 
         {    
 
             if (m_dwCookie)    
 
             {    
 
                 aResult = m_ConnectionPoint->Unadvise(m_dwCookie);    
 
                 m_dwCookie = 0;    
 
             }    
 
  
 
             m_ConnectionPoint->Release();    
 
             m_ConnectionPoint = NULL;    
 
         }    
 
  
 
         return aResult;    
 
     }    
 
  
 
     HRESULT STDMETHODCALLTYPE QueryInterface(REFIID riid, LPVOID* ppv)    
 
     {    
 
         *ppv = NULL;    
 
  
 
         if (riid == IID_IUnknown)    
 
         {    
 
             *ppv = (LPUNKNOWN)this;    
 
             AddRef();    
 
             return S_OK;    
 
         }
