用RealPlayer控件制作的播放器

 本文介绍如何插入RealPlay控件实现媒体文件的播放，代码运行效果图如下：



下面简要介绍一下具体实现步骤：

一、建立基于对话框的程序

二、在对话框内添加RealPlayer G2 control的ActiveX控件
(工程->添加工程->compontent and controls->registed ActiveX controls )。

三、在对话框内添加源程序内所示的按钮和静态文本 分别用于控制打开播放等控制及显示歌曲信息 其ID号如源程序

四、用MFC映射各按钮消息

void CSunapplerealplayerDlg::OnOpen() 
{
char szFileFilter[]=
        "RM File(*.rm)|*.rm|"
		"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 dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY,szFileFilter);
	if(dlg.DoModal()==IDOK){
		CString PathName=dlg.GetPathName();
		PathName.MakeUpper();
		m_player->SetSource(PathName);
		m_player->DoPlay();
		SetDlgItemText(IDC_STATIC1,m_player->GetAuthor());
	    SetDlgItemText(IDC_STATIC2,m_player->GetTitle());
	    SetDlgItemText(IDC_COPYRIGHT,m_player->GetCopyright());
	    SetDlgItemText(IDC_SOURCE,m_player->GetSource());
	}	
}

void CSunapplerealplayerDlg::OnPlay() 
{    
	SetDlgItemText(IDC_STATIC1,m_player->GetAuthor());
	SetDlgItemText(IDC_STATIC2,m_player->GetTitle());
	SetDlgItemText(IDC_COPYRIGHT,m_player->GetCopyright());
	SetDlgItemText(IDC_SOURCE,m_player->GetSource());
    m_player->DoPlay();
	
	UpdateData(false);
	SetTimer(1,20,NULL);
}

void CSunapplerealplayerDlg::OnTimer(UINT nIDEvent) 
{
   if(0&&isRepeat)
		m_player->DoPlay();
	CDialog::OnTimer(nIDEvent);
}

void CSunapplerealplayerDlg::OnClose() 
{
	///////添加此代码时不要忘了在stdafx.h开头处添加前两行
	AnimateWindow(GetSafeHwnd(),1000,AW_HIDE|AW_BLEND);
	KillTimer(0);
////////////////////////////////////
//此处采用DestroyWindow关闭窗口
///////////////////////////////////
	this->DestroyWindow();
	
}

void CSunapplerealplayerDlg::OnFullscreen() 
{
	 m_player->DoPause();
	 m_player->SetFullScreen();
	 m_player->DoPlay();
}

void CSunapplerealplayerDlg::OnMp3down() 
{
	ShellExecute(NULL,_T("open"),"http://sunapple.51.net",NULL,NULL,TRUE); 
	
}

void CSunapplerealplayerDlg::OnPause() 
{
 
	m_player->DoPause();
}

void CSunapplerealplayerDlg::OnStop() 
{
   	m_player->DoStop();
	KillTimer(0);
}

void CSunapplerealplayerDlg::OnRepeat() 
{   
    m_player->SetLoop(true);
	if(isRepeat){
		isRepeat=FALSE;
		SetDlgItemText(IDC_REPEAT,"循环");
   }
   else
   {
	   isRepeat=TRUE;
	   SetDlgItemText(IDC_REPEAT,"正常");
   }
}


void CSunapplerealplayerDlg::OnLower() 
{
	// TODO: Add your control notification handler code here
	short volume=m_player->GetVolume();
	m_player->DoPause();
	m_player->SetVolume(volume-100);
	m_player->DoPlay();
}

void CSunapplerealplayerDlg::OnUpper() 
{
	// TODO: Add your control notification handler code here
	short volume=m_player->GetVolume();
	m_player->DoPause();
	m_player->SetVolume(volume+100);
	m_player->DoPlay();
}

void CSunapplerealplayerDlg::OnFloat() 
{
	//   TODO: Add your command handler code here
	ShellExecute(NULL,_T("open"),"http://sunapple.51.net",NULL,NULL,TRUE); 
}

void CSunapplerealplayerDlg::OnPetroleum() 
{
	// TODO: Add your command handler code here
	ShellExecute(NULL,_T("open"),"http://www.hdpu.edu.cn",NULL,NULL,TRUE); 
}

五、映射WM_CTLCOLOR消息，用于控制文本显示的颜色

HBRUSH CSunapplerealplayerDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
	
    if(nCtlColor==CTLCOLOR_STATIC)
		if(pWnd.GetDlgCtrlID()==IDC_VOLUME)
		{
			pDC.SetTextColor(RGB(165,182,222));
			pDC.SetBkMode(TRANSPARENT);
			return (HBRUSH) m_brush.GetSafeHandle();
		}
		if(pWnd.GetDlgCtrlID()==IDC_STATIC1||pWnd.GetDlgCtrlID()==IDC_STATIC2
		||pWnd.GetDlgCtrlID()==IDC_SOURCE||pWnd.GetDlgCtrlID()==IDC_COPYRIGHT)
		{
			pDC.SetTextColor(RGB(0,0,255));
			pDC.SetBkMode(TRANSPARENT);
			return (HBRUSH) m_brush.GetSafeHandle();
		}
		if(pWnd.GetDlgCtrlID()==IDC_STATIC||pWnd.GetDlgCtrlID()==IDC_INFO)
		{
         pDC.SetTextColor(RGB(255,0,0));
			pDC.SetBkMode(TRANSPARENT);
			return (HBRUSH) m_brush.GetSafeHandle();
		}
	// TODO: Return a different brush if the default is not desired
	return hbr;
}

六、在APP类里的initInstance()里添加下面函数改变对话框背景。

SetDialogBkColor(RGB(206,227,99));

七、为了美观我们的外形可引入CButtonXP类,将个按钮类型设置为CButtonXP
