资源说明: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.
//

ctrl+w打开类向导,如图,添加ontimer函数

second++;

UpdateData(false);
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
{

mp3.Stop();
mp3.Load(this->m_hWnd,strfilename);
mp3.Play();
SetTimer(0,1000,NULL);
}
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;
MCI_OPEN_PARMS mciopenparms;
DWORD DeviceID;
DeviceID=mciopenparms.wDeviceID;
mciSendCommand(DeviceID,MCI_SETAUDIO,MCI_DGV_SETAUDIO_VALUE|MCI_DGV_SETAUDIO_ITEM,(DWORD)(LPVOID)&mcisetvolumn);
// return mcisetvolumn.dwValue;
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
