如何把avi插入到网页里_IT百科

1打开DW选择插入-媒体-activex(c)然后选择AVI文件

2用embed方法插入例如下列格式： <Embed src="url"width="宽度"height="高度"AUTOSTART="TRUE│false" LOOP="TRUE"></Embed>

建立一个对话框 IDD_PLAYER_DIALOG

在对话框上单击右键,选择添加类,基类选择CDialog, 类名CPlayer,确定,生成CPlayer类

在对话框上单击右键,选择插入Activex控件,拖到底部,选择windows media player,确定

,控件被加入.

关闭资源视图.

选择菜单, 项目->添加类, 在模板中选择"在Activex控件中的MFC类".在"可用的Activex

控件"下拉菜单中选择"Windows Media Player", 在左下方的接口栏中出现可以选择的类

的接口,选择需要的接口即可,这里选择IWMPPlyaer4,单击完成生成类CWMPPlayer4.

打开资源视图,在对话框的wmp控件上单击右键,添加变量, 变量类型输入CWMPPlayer4,变

量名m_ctrlPlayer.

调用m_ctrlPlayer.put_url() 可以播放媒体文件. ------------

-------------------------------------------------------------

件——》新建——》项目，选择MFC应用程序——》名称为player——》确定。

点击应用程序类型——》基于对话框——》完成。

在DIALOG中右击——》插入ACTIVEX控件——》选Windows Media Player ，添加了Windows Media Player 控件ID为IDC_OCX1。

对Windows Media Player控件右击——》添加变量——》变量名为m_wmplayer——》完成。

拉二个按钮到DIALOG中“打开”和“暂停”，双击“打开”输入以下代码：

// TODO: 在此添加控件通知处理程序代码

TCHAR szFileFilter[]= _T("Mp3 File(*.mp3)|*.mp3|MPEG File(*.mpeg)|*.mpeg|Media File(*.asf)|*.asf|Video File(*.dat)|*.dat|MPGA File(*.mpga)|*.mpga|Wave File(*.wav)|*.wav|AVI File(*.avi)|*.avi|Movie File(*.mov)|*.mov|Mid File(*.mid*,rmi)|*.mid*.rmi|Wma File(*.wma)|*.wma|All File(*.*)|*.*||")

CFileDialog fileDialog( TRUE,NULL,NULL,NULL,szFileFilter,this)

if (fileDialog.DoModal() == IDOK)

{

CString fileName=fileDialog.GetPathName()

m_wmplayer.put_URL(fileName)

}

到此时一切正常~

然后右击类视图/解决方案—〉添加类—〉选择“Active中的MFC类”—〉选择windows media player <1.0>选择所有接口生成类。

在然后在对话框头文件中（playerDlg.h）添加了以下变量：

CWMPControls m_control

在playerDlg.cpp的OnInitDialog（）中添加代码：

m_control = static_cast <CWMPControls>(m_wmPlayer.get_controls())

双击“暂停”输入

// TODO: 在此添加控件通知处理程序代码

m_control.pause()

void CPlayerDlg::OnBnClickedButtonOpen()

{

// TODO: 在此添加控件通知处理程序代码

CFileDialog fileDialog( TRUE,NULL,NULL,NULL,szFileFilter,this)

if (fileDialog.DoModal() == IDOK)

{

CString fileName=fileDialog.GetPathName()

m_conWMPlayer.put_URL(fileName)

}

void CPlayerDlg::OnBnClickedButtonStop()

{

// TODO: 在此添加控件通知处理程序代码

m_CWMPConcontrol.pause()

}

BOOL CPlayerDlg::OnInitDialog()

{

CDialog::OnInitDialog()

//todo

m_CWMPConcontrol=static_cast<CWMPControls>(m_conWMPlayer.get_controls())

}
