使用MFC制作MP3打开vc6.0，建立如图所示mfc工程文件 选择基于对话框的确定 删除所有空间，建立如图所示对话框 属性如下： 播放 IDC_open； 添加 IDC_fileopen； 暂停 IDC_pause； 删除 IDC_del； 停止 IDC_stop； 退出 IDC_exit； 音乐名编辑框 IDC_filename； 音量控制滑块 IDC_SLIDER1； 音量控制编辑框 IDC_vol； 建立类向导对应如下： 在工程文件，右键，插入，bitmap位图 引入你想插入的背景图，必须是bmp格式的 进入你的dlg.cpp文件 在onpaint函数下添加代码 void CMp3Dlg::OnPaint() { if (IsIconic()) { CPaintDC dc(this); // device context for painting SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0); // Center icon in client rectangle int cxIcon = GetSystemMetrics(SM_CXICON); int cyIcon = GetSystemMetrics(SM_CYICON); CRect rect; GetClientRect(&rect); int x = (rect.Width() - cxIcon + 1) / 2; int y = (rect.Height() - cyIcon + 1) / 2; // Draw the icon dc.DrawIcon(x, y, m_hIcon); } else { //CDialog::OnPaint(); CPaintDC dc(this); CRect rect; GetClientRect(&rect); CDC dcMem; dcMem.CreateCompatibleDC(&dc); CBitmap bmpBackground; bmpBackground.LoadBitmap(IDB_BITMAP6); /IDB_BITMAP6是你的位图地址 BITMAP bitmap; bmpBackground.GetBitmap(&bitmap); CBitmap *pbmpOld=dcMem.SelectObject(&bmpBackground); dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,bitmap.bmWidth,bitmap.bmHeight,SRCCOPY); } } 编译运行，你就会看到背景有图片了。 插入-类，找到geneticclass，类名mp3.cpp 你会发现在头文件中多了一个mp3.h文件 在mp3.h文件中添加代码如下 // Mp3.h: interface for the Mp3 class. // ////////////////////////////////////////////////////////////////////// #if !defined(AFX_MP3_H__20D325E5_A96A_43FE_A485_92F57C68DD0D__INCLUDED_) #define AFX_MP3_H__20D325E5_A96A_43FE_A485_92F57C68DD0D__INCLUDED_ #if _MSC_VER > 1000 #pragma once #endif // _MSC_VER > 1000 #include "Mmsystem.h" class Mp3 { public: Mp3();

} 在dlg.cpp文件的public中添加一行代码：int hour,minute,second; 在CMp3Dlg::CMp3Dlg(CWnd* pParent /*=NULL*/)中添加如下 CMp3Dlg::CMp3Dlg(CWnd* pParent /*=NULL*/) : CDialog(CMp3Dlg::IDD, pParent) { //{{AFX_DATA_INIT(CMp3Dlg) m_int = 0;

} ctrl+w打开类向导，如图，添加ontimer函数 代码如下： void CMp3Dlg::OnTimer(UINT nIDEvent) { // TODO: Add your message handler code here and/or call default CString mtime; Mp3 mp3; second++; CClientDC dc(this); dc.SetBkColor(RGB(124,252,0));//设置放置计数器区域的外观 dc.SetTextColor(RGB(255,255,203));//设置数字显示的颜色 if(second==60)//设置钟表的显示 { minute++;second=0;

CDialog::OnTimer(nIDEvent); } ctrl+w打开类向导添加函数如下 void CMp3Dlg::OnDblclkList() //在列表中选中，双击左键播放音乐 { CString mtime; Mp3 mp3; CClientDC dc(this); hour=0;minute=0;second=0; dc.SetBkColor(RGB(124,252,0));//设置放置计数器区域的外观 dc.SetTextColor(RGB(255,255,203));//设置数字显示的颜色 mtime.Format("d:d:d",hour,minute,second);//显示时间进度 dc.TextOut(280,128,mtime);

} 打开类向导，添加函数如下 void CMp3Dlg::OnCustomdrawSlider1(NMHDR* pNMHDR, LRESULT* pResult) { // TODO: Add your control notification handler code here UpdateData(true); m_int=m_slider.GetPos()/10; Setvolumn(m_slider.GetPos()); UpdateData(false); *pResult = 0; } 打开类向导，添加函数如下 void CMp3Dlg::OnReleasedcaptureSlider1(NMHDR* pNMHDR, LRESULT* pResult) { // TODO: Add your control notification handler code here Setvolumn(m_slider.GetPos()); *pResult = 0; } 添加声音设置函数如下 DWORD CMp3Dlg::Setvolumn(DWORD vol) { MCI_DGV_SETAUDIO_PARMS mcisetvolumn; mcisetvolumn.dwCallback=NULL; mcisetvolumn.dwItem=MCI_DGV_SETAUDIO_VOLUME; mcisetvolumn.dwValue=vol;

return 0; } 到此已经基本完成了，我们可以试听一下 接下来我们可以到包成exe可执行文件，为了去掉那个不好看的图标，我们可以进入res文件夹，把原来的图标删掉，不过，你要放入一个cio格式的图片作为图标，cio格式网上有很多转换的，删掉原图标后，程序会自动生成一个你放进去的图标。接下来演示打包： 工程，设置，或者按alt+f7，如图设置 组建，批组建，如图 创建完成后，你就会发现在你的工程文件中多了一个release文件夹，打开找到exe，这个文件就是打包好的，随便放到哪里都可以执行，至此，工作基本完成了，最后附上源代码，仅供参考 dlg.cpp文件 // Mp3播放器Dlg.cpp : implementation file // #include "stdafx.h" #include "Mp3播放器.h" #include "Mp3播放器Dlg.h" #include "Mmsystem.h" #include "Digitalv.h" #include "Mp3.h" //音量控制用到 #pragma comment(lib,"Winmm.lib") #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__;
