请问，如何通过VC，根据简谱播放音乐？

如题，给点思路或资料链接都可以，谢谢了

lz，你看这样行不：
要让程序播放不同的乐曲,必须让程序认得发什么音,先定义乐谱,如:
int nMusic[] = {1,2,3,4,5,6,7,10,11,12,13,14,15,16,17,........};

这样乐谱文件就包含1564564564564564.....这样的数据,读文件让程序发声…………

不知道这样是否可行？你试试看。

BOOL Beep(
DWORD dwFreq, // 声音频率
DWORD dwDuration // 声音持续时间
);

请问：BOOL Beep(
DWORD dwFreq, // 声音频率
DWORD dwDuration // 声音持续时间
);
中，声音频率和简谱的对应关系是怎样的，比如，我想播放 1，应该用多少频率？

这个问题有点意思，关注。。:)

很多C语言的书上都有~

PlaySound
The PlaySound function plays a sound specified by the given filename, resource, or system event. (A system event may be associated with a sound in the registry or in the WIN.INI file.)

BOOL PlaySound(
LPCSTR pszSound,
HMODULE hmod,
DWORD fdwSound
);
Parameters
pszSound
A string that specifies the sound to play. If this parameter is NULL, any currently playing waveform sound is stopped. To stop a non-waveform sound, specify SND_PURGE in the fdwSound parameter.
Three flags in fdwSound (SND_ALIAS, SND_FILENAME, and SND_RESOURCE) determine whether the name is interpreted as an alias for a system event, a filename, or a resource identifier. If none of these flags are specified, PlaySound searches the registry or the WIN.INI file for an association with the specified sound name. If an association is found, the sound event is played. If no association is found in the registry, the name is interpreted as a filename.

hmod
Handle to the executable file that contains the resource to be loaded. This parameter must be NULL unless SND_RESOURCE is specified in fdwSound.
fdwSound
Flags for playing the sound. The following values are defined. Value Meaning
SND_APPLICATION The sound is played using an application-specific association.
SND_ALIAS The pszSound parameter is a system-event alias in the registry or the WIN.INI file. Do not use with either SND_FILENAME or SND_RESOURCE.
SND_ALIAS_ID The pszSound parameter is a predefined sound identifier.
SND_ASYNC The sound is played asynchronously and PlaySound returns immediately after beginning the sound. To terminate an asynchronously played waveform sound, call PlaySound with pszSound set to NULL.
SND_FILENAME The pszSound parameter is a filename.
SND_LOOP The sound plays repeatedly until PlaySound is called again with the pszSound parameter set to NULL. You must also specify the SND_ASYNC flag to indicate an asynchronous sound event.
SND_MEMORY A sound event's file is loaded in RAM. The parameter specified by pszSound must point to an image of a sound in memory.
SND_NODEFAULT No default sound event is used. If the sound cannot be found, PlaySound returns silently without playing the default sound.
SND_NOSTOP The specified sound event will yield to another sound event that is already playing. If a sound cannot be played because the resource needed to generate that sound is busy playing another sound, the function immediately returns FALSE without playing the requested sound.
If this flag is not specified, PlaySound attempts to stop the currently playing sound so that the device can be used to play the new sound.

SND_NOWAIT If the driver is busy, return immediately without playing the sound.
SND_PURGE Sounds are to be stopped for the calling task. If pszSound is not NULL, all instances of the specified sound are stopped. If pszSound is NULL, all sounds that are playing on behalf of the calling task are stopped.
You must also specify the instance handle to stop SND_RESOURCE events.

SND_RESOURCE The pszSound parameter is a resource identifier; hmod must identify the instance that contains the resource.
SND_SYNC Synchronous playback of a sound event. PlaySound returns after the sound event completes.


Return Values
Returns TRUE if successful or FALSE otherwise.

Remarks
The sound specified by pszSound must fit into available physical memory and be playable by an installed waveform-audio device driver. PlaySound searches the following directories for sound files: the current directory; the Windows directory; the Windows system directory; directories listed in the PATH environment variable; and the list of directories mapped in a network. For more information about the directory search order, see the documentation for the OpenFile function.

If it cannot find the specified sound, PlaySound uses the default system event sound entry instead. If the function can find neither the system default entry nor the default sound, it makes no sound and returns FALSE.

我已经实现了，不过声音很难听，呵呵
