WTL对 Flash 控件的使用

MFC和 WTL 对Flash 控件的使用，都差不多，以WTL为例进行说明：?

1. 首先使用向导创建一个基于对话框的应用程序，然后在 在maindlg 创建之前加入?AtlAxWinInit()，?

2. 在主对话框中增加?CAxWindow m_PlayerHostWnd;
CComPtr<IShockwaveFlash> m_FlashPlayer;

3. 在资源中增加一个Flash控件，右键菜单，Insert ActiveX control 的哪项，然后进行拖放大小。

4.

// Load the flash player?
m_PlayerHostWnd = GetDlgItem( IDC_SHOCKWAVEFLASH_PLAYER );
LRESULT lResult = m_PlayerHostWnd.QueryControl( &m_FlashPlayer );
if ( FAILED( lResult ) )
{
MessageBox(L"Can not Load the active X");
return FALSE;
}

如下的语句可以初始化完毕了，

5.? _bstr_t strMovieName( strPath.GetBuffer(strPath.GetLength()) );


lResult = m_FlashPlayer->put_Movie( strMovieName );

就是播放了。

6. 增加Flash的Event响应，那么就要将自己的类派生自IDispEventImpl<IDC_SHOCKWAVEFLASH_PLAYER,CMainDlg>

class CMainDlg : public CAxDialogImpl<CMainDlg>,
public IDispEventImpl<IDC_SHOCKWAVEFLASH_PLAYER,CMainDlg>

7. 增加如下代码在 LRESULT OnInitDialog(UINT /*uMsg*/,WPARAM /*wParam*/,LPARAM /*lParam*/,BOOL& /*bHandled*/) 中

AtlAdviseSinkMap( this,?true );

8. 使用?

BEGIN_SINK_MAP(CMainDlg)
SINK_ENTRY(IDC_SHOCKWAVEFLASH_PLAYER,150,HandleFSCommand)
SINK_ENTRY(IDC_SHOCKWAVEFLASH_PLAYER,1958,OnFlashPlayerProgress)
END_SINK_MAP()

建立 事件处理分配表，并且实现响应的函数。

9. 一定要记得在关闭窗口的时候，或者窗口类销毁的时候，调用AtlAdviseSinkMap( this,?false);
