[置顶] c++播放Flash文件

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：
