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，所以可以参考前一篇文章http://blog.csdn.net/xueyunf/article/details/9160657，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。

#include <atlbase.h>
extern CComModule _Module;
#include <atlwin.h>
#include <comdef.h>
#include "flash32_11_7_700_224.tlh"
#include <string>
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<IShockwaveFlash> 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;   }   else if (riid == IID_IDispatch)   {   *ppv = (IDispatch*)this;   AddRef();   return S_OK;   }   else if (riid == __uuidof(ShockwaveFlashObjects::_IShockwaveFlashEvents))   {   *ppv = (ShockwaveFlashObjects::_IShockwaveFlashEvents*) this;   AddRef();   return S_OK;   }   else   {      return E_NOTIMPL;   }   }   ULONG STDMETHODCALLTYPE AddRef()   {     return ++m_nRefCount;   }   ULONG STDMETHODCALLTYPE Release()   {     int aRefCount = --m_nRefCount;   if (aRefCount == 0)        delete this;           return aRefCount;   }   // IDispatch method   virtual HRESULT STDMETHODCALLTYPE GetTypeInfoCount(UINT* pctinfo)   {   return E_NOTIMPL;   }   virtual HRESULT STDMETHODCALLTYPE GetTypeInfo(UINT iTInfo, LCID lcid, ITypeInfo** ppTInfo)   {   return E_NOTIMPL;    }   virtual HRESULT STDMETHODCALLTYPE GetIDsOfNames(REFIID riid, LPOLESTR* rgszNames,   UINT cNames, LCID lcid,DISPID* rgDispId)   {   return E_NOTIMPL;    }   virtual HRESULT STDMETHODCALLTYPE Invoke(DISPID dispIdMember, REFIID riid, LCID lcid,   WORD wFlags, ::DISPPARAMS __RPC_FAR *pDispParams, VARIANT __RPC_FAR *pVarResult,   ::EXCEPINFO __RPC_FAR *pExcepInfo, UINT __RPC_FAR *puArgErr)   {   switch(dispIdMember)   {   case 0x7a6:            break;   case 0x96:             if ((pDispParams->cArgs == 2) &&   (pDispParams->rgvarg[0].vt == VT_BSTR) &&   (pDispParams->rgvarg[1].vt == VT_BSTR))   {   FSCommand(pDispParams->rgvarg[1].bstrVal, pDispParams->rgvarg[0].bstrVal);   }   break;   case DISPID_READYSTATECHANGE:                      break;   default:               return DISP_E_MEMBERNOTFOUND;   }    return NOERROR;   }   HRESULT OnReadyStateChange (long newState)   {   MessageBox(NULL,L"",L"Read",MB_OK);return S_OK;   }   HRESULT OnProgress(long percentDone )   {   MessageBox(NULL,L"",L"Done",MB_OK);return S_OK;   }   HRESULT FSCommand (_bstr_t command, _bstr_t args)   {   //         if (m_pFlashWidget != NULL)   //             m_pFlashWidget->FlashCommand((char*) command, (char*) args);   return S_OK;   }
};

当然这也很简单，我们只要明白Flash的机制就可以了。后边是Flash播放的一些简单的处理

可以看到红色部分是被我修改过的地方，这些东西虽然不难，但是自己做起来没有资料的时候也挺不方便的！这样Flash的播放就好了，但是不知道为什么停止和开始播放按钮对某些Flash动画不起作用。好了就说这么多！因为有些童鞋可能比较没有时间，所以直接附上源码在最后方便修改和使用！http://download.csdn.net/detail/xueyunf/5658183当然也同样给出一个运行的结果截图：
