帮顶。

使用VC++0.6环境编写，使用了内置的MCI接口进行多媒体音频的处理，使用MFC编写界面。适合MFC的初学者学习。

用MCI32.ocx控件，简单实现播放mp3的例子

一款很不错的录音程序，附带源代码，自行编译：如遇到内存不能读写错误（103行），请把编译 CPU Type 从“Any CPU”改为“x86”即可。部分代码： public const string WaveAudio = "waveaudio"; public const uint MM_MCINOTIFY = 0x3B9; public const uint MCI_NOTIFY_SUCCESSFUL = 0x0001; public const uint MCI_NOTIFY_SUPERSEDED = 0x0002; public const uint MCI_NOTIFY_ABORTED = 0x0004; public const uint MCI_NOTIFY_FAILURE = 0x0008; public const uint MCI_OPEN = 0x0803; public const uint MCI_CLOSE = 0x0804; public const uint MCI_PLAY = 0x0806; public const uint MCI_SEEK = 0x0807; public const uint MCI_STOP = 0x0808; public const uint MCI_PAUSE = 0x0809; public const uint MCI_RECORD = 0x080F; public const uint MCI_RESUME = 0x0855; public const uint MCI_SAVE = 0x0813; public const uint MCI_LOAD = 0x0850; public const uint MCI_STATUS = 0x0814; public const uint MCI_SAVE_FILE = 0x00000100; public const uint MCI_OPEN_ELEMENT = 0x00000200; public const uint MCI_OPEN_TYPE = 0x00002000; public const uint MCI_LOAD_FILE = 0x00000100; public const uint MCI_STATUS_POSITION = 0x00000002; public const uint MCI_STATUS_LENGTH = 0x00000001; public const uint MCI_STATUS_ITEM = 0x00000100; public const uint MCI_NOTIFY = 0x00000001; public const uint MCI_WAIT = 0x00000002; public const uint MCI_FROM = 0x00000004; public const uint MCI_TO = 0x00000008; // Structures [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_OPEN_PARMS { public IntPtr dwCallback; public uint wDeviceID; public IntPtr lpstrDeviceType; public IntPtr lpstrElementName; public IntPtr lpstrAlias; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_RECORD_PARMS { public IntPtr dwCallback; public uint dwFrom; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_PLAY_PARMS { public IntPtr dwCallback; public uint dwFrom; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_GENERIC_PARMS { public IntPtr dwCallback; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_SEEK_PARMS { public IntPtr dwCallback; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_SAVE_PARMS { public IntPtr dwCallback; public IntPtr lpfilename; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_STATUS_PARMS { public IntPtr dwCallback; public uint dwReturn; public uint dwItem; public uint dwTrack; } ; // Functions [DllImport("winmm.dll", CharSet = CharSet.Ansi, BestFitMapping = true, ThrowOnUnmappableChar = true)] [return: MarshalAs(UnmanagedType.U4)] public static extern uint mciSendCommand( uint mciId, uint uMsg, uint dwParam1, IntPtr dwParam2); [DllImport("winmm.dll", CharSet = CharSet.Ansi, BestFitMapping = true, ThrowOnUnmappableChar = true)] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool mciGetErrorString( uint mcierr, [MarshalAs(UnmanagedType.LPStr)] System.Text.StringBuilder pszText, uint cchText); } }

一个使用MFC写的使用mci播放音频文件的小程序，可播放MP3等主流格式

FLASH.OCX 和 MIC32.OCX
