如何播放背景音乐？(10分)

各位大虾，请多多指教！
我的程序在作其他操作时，比如窗体的重画，如何同步的播放背景音乐？

TMediaPlayer控件！

可以试一下采用多线程技术

感谢楼上这位，能否在指导指导？
我试过多线程，结果窗体重画到一半，程序开始播放音乐，然后继续重画。
修改优先级也无法完成。

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 of 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:

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 begin
ning 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 thedo
cumentation 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.

就像播放幻灯片的同时，可以听听背景音乐。

有没有高手？

PlaySound函数里面有一参数就是同步；

listen

使用API函数PlaySound,要引用mmSystem单元

同意，说的够清楚的了

wuqiu,don't paste the Delphi API Help Directly please!
I agree with Undefine and hunter0401

使用mediaplayer控件+midi就可以了。
