./第一步：打開vc6.0,建立如圖所示mfc工程文件選擇基于對話框的確定刪除所有空間,建立如圖所示對話框屬性如下：播放IDC_open；添加IDC_fileopen；暫停IDC_pause；刪除IDC_del；停止IDC_stop；退出IDC_exit；音樂名編輯框IDC_filename；音量控制滑塊IDC_SLIDER1；音量控制編輯框IDC_vol；建立類向導對應如下：在工程文件,右鍵,插入,bitmap位圖引入你想插入的背景圖,必須是bmp格式的進入你的dlg.cpp文件在onpaint函數下添加代碼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是你的位圖地址 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>; }}編譯運行,你就會看到背景有圖片了。插入-類,找到geneticclass,類名mp3.cpp你會發現在頭文件中多了一個mp3.h文件在mp3.h文件中添加代碼如下//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<>; virtual~Mp3<>;HWNDm_hWnd;//????μ±?°′°?úμ???±ú DWORDDeviceID;//???¨2￥·?ò?à?μ?éè±?IDMCI_OPEN_PARMSmciopenparms;//???¨′ò?aò?à????tμ?2?êyvoidLoad<HWNDhwnd,CStringStrfilepath>; DWORDgetinformation<DWORDitem>; voidPlay<>; voidPause<>; voidresum<>; voidStop<>;};#endif//!defined<AFX_MP3_H__20D325E5_A96A_43FE_A485_92F57C68DD0D__INCLUDED_>在mp3.cpp中添加如下代碼//Mp3.cpp:implementationoftheMp3class.////////////////////////////////////////////////////////////////////////#include"stdafx.h"#include"Mp32￥·??÷.h"#include"Mp3.h"#ifdef_DEBUG#undefTHIS_FILEstaticcharTHIS_FILE[]=__FILE__;#definenewDEBUG_NEW#endif////////////////////////////////////////////////////////////////////////Construction/Destruction//////////////////////////////////////////////////////////////////////Mp3::Mp3<>{}Mp3::~Mp3<>{}voidMp3::Load<HWNDhwnd,CStringStrfilepath>{ m_hWnd=hwnd; mciSendCommand<DeviceID,MCI_CLOSE,0,0>;//?ó?????t?°?è??3yé?′?éè?? mciopenparms.lpstrElementName=Strfilepath;//??ò?à????t?·??′???éè±?
