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

//多谢杜修杏 老师指点

///////////////////////////////////

	this->DestroyWindow();

	

}



void CSunapplerealplayerDlg::OnFullscreen() 

{

	 m_player->DoPause();

	 m_player->SetFullScreen();

	 m_player->DoPlay();

}



void CSunapplerealplayerDlg::OnMp3down() 

{

	ShellExecute(NULL,_T("open"),"",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"),"",NULL,NULL,TRUE); 

}



void CSunapplerealplayerDlg::OnPetroleum() 

{

	// TODO: Add your command handler code here

	ShellExecute(NULL,_T("open"),"",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

好了，应该大功告成了！调试一下吧！
本程序在调试过程中要多谢杜修杏老师的指点。
