用MFC做MP3音乐播放器-超实用

./第一步：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voidCMp3Dlg::OnPaint<>{ if<IsIconic<>> { CPaintDCdc<this>;//devicecontextforpainting SendMessage<WM_ICONERASEBKGND,<WPARAM>dc.GetSafeHdc<>,0>; //Centericoninclientrectangle intcxIcon=GetSystemMetrics<SM_CXICON>; intcyIcon=GetSystemMetrics<SM_CYICON>; CRectrect; GetClientRect<&rect>; intx=<rect.Width<>-cxIcon+1>/2; inty=<rect.Height<>-cyIcon+1>/2; //Drawtheicon dc.DrawIcon<x,y,m_hIcon>; } else { //CDialog::OnPaint<>; CPaintDCdc<this>; CRectrect; GetClientRect<&rect>; CDCdcMem; dcMem.CreateCompatibleDC<&dc>; CBitmapbmpBackground; bmpBackground.LoadBitmap<IDB_BITMAP6>;/IDB_BITMAP6是你的位图地址 BITMAPbitmap; 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:interfacefortheMp3class.////////////////////////////////////////////////////////////////////////#if!defined<AFX_MP3_H__20D325E5_A96A_43FE_A485_92F57C68DD0D__INCLUDED_>#defineAFX_MP3_H__20D325E5_A96A_43FE_A485_92F57C68DD0D__INCLUDED_#if_MSC_VER>1000#pragmaonce#endif//_MSC_VER>1000#include"Mmsystem.h"classMp3{public: Mp3<>;
