基于MFC的音乐播放器vc6.0.doc

1. 新建一个基于对话框的player工程，对话框如图：2. 各个控件属性如下图：3. 在头文件playerDlg.h中添加如下：#if !defined(AFX_PLAYERDLG_H_A2A8C582_CC8E_4EED_85A6_7AC126703D36_INCLUDED_)#define AFX_PLAYERDLG_H_A2A8C582_CC8E_4EED_85A6_7AC126703D36_INCLUDED_#if _MSC_VER 1000#pragma once#endif / _MSC_VER 1000/ CPlayerDlg dialogclass CPlayerDlg : public CDialog/ Constructionpublic:CPlayerDlg(CWnd* pParent = NULL);/ standard constructorCString m_title;/歌曲名称UINT m_count;/标志DWORD cdlen; /歌曲时间CString FileName;BOOL m_flag;int i;int second,hour,minute;int m_max;CString stime;/播放时长CString allTime;/歌曲总时长DWORD cdfrom,cdto,aa;/歌曲的起点和终点/ Dialog Data/AFX_DATA(CPlayerDlg)enum IDD = IDD_PLAYER_DIALOG ;CStaticm_playing;CStaticm_ST_Pause;CSliderCtrlm_setvoice;CSliderCtrlm_control;CButtonm_delete;CButtonm_per;CButtonm_next;CButtonm_play;CButtonm_pause;CListBoxm_list2;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CPlayerDlg)protected:virtual void DoDataExchange(CDataExchange* pDX);/ DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:HICON m_hIcon;/ Generated message map functions/AFX_MSG(CPlayerDlg)virtual BOOL OnInitDialog();afx_msg void OnSysCommand(UINT nID, LPARAM lParam);afx_msg void OnPaint();afx_msg HCURSOR OnQueryDragIcon();afx_msg void AddSong();afx_msg void stopPlay();afx_msg void playSong(CString str);afx_msg void OnButtonPause();afx_msg void DelSong();afx_msg void OnSelchangelist();afx_msg void songListDBClk();afx_msg void NextSong();afx_msg DWORD setvolume(DWORD vol);afx_msg void preSong();afx_msg void OnTimer(UINT nIDEvent) ;afx_msg void OnButton1();afx_msg void deltSong();afx_msg DWORD getinfo(DWORD item);afx_msg void OnVoice(NMHDR* pNMHDR, LRESULT* pResult);afx_msg void Onsetvoices(NMHDR* pNMHDR, LRESULT* pResult);afx_msg void OnPrevis();afx_msg void OnNexts();afx_msg void Onexit();/AFX_MSGDECLARE_MESSAGE_MAP();4. 在playerDlg.cpp中的函数如下/ playerDlg.cpp : implementation file/#include stdafx.h#include player.h#include playerDlg.h#pragma comment(lib,winmm.lib)#include mmsystem.h#include Digitalv.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App AboutCString *songName= new CString 100;class CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CPlayerDlg dialogCPlayerDlg:CPlayerDlg(CWnd* pParent /*=NULL*/): CDialog(CPlayerDlg:IDD, pParent)m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CPlayerDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CPlayerDlg)DDX_Control(pDX, IDC_PLAYING, m_playing);DDX_Control(pDX, IDC_ST_Pause, m_ST_Pause);DDX_Control(pDX, IDC_voice, m_setvoice);DDX_Control(pDX, IDC_BUTTON_DEL_SONG, m_delete);DDX_Control(pDX, IDC_BUTTON_PRE, m_per);DDX_Control(pDX, IDC_BUTTON_NEXT, m_next);DDX_Control(pDX, IDC_BUTTON_PAUSE, m_play);DDX_Control(pDX, m_list, m_list2);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CPlayerDlg, CDialog)/AFX_MSG_MAP(CPlayerDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(IDC_BUTTON_ADD_SONG, AddSong)ON_BN_CLICKED(IDC_BUTTON_PAUSE, OnButtonPause)ON_BN_CLICKED(IDC_BUTTON_DEL_SONG, DelSong)ON_LBN_DBLCLK(m_list, songListDBClk)ON_BN_CLICKED(IDC_BUTTON_NEXT, NextSong)ON_BN_CLICKED(IDC_BUTTON_PRE, preSong)ON_WM_TIMER()ON_NOTIFY(NM_RELEASEDCAPTURE, IDC_voice, Onsetvoices)ON_BN_CLICKED(IDC_BUTTON_PREVIS, OnPrevis)ON_BN_CLICKED(IDC_BUTTON_NEXTS, OnNexts)ON_BN_CLICKED(IDC_exit, Onexit)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CPlayerDlg message handlersBOOL CPlayerDlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu.m_max=0;/进度条的最大位置初始值为0/ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
