Playing Sounds Specified in the Registry
function will also play sounds referred to by a keyname in the registry. This
allows users to assign their own sounds to system alerts and warnings, or to
user actions, such as a mouse button click. Sounds that are associated with
system alerts and warnings are called sound events
To play a sound event, call PlaySound
with the pszSound
parameter pointing to a string containing the name of the registry entry that
identifies the sound. For example, to play the sound associated with the
"MouseClick" entry and to wait for the sound to complete before returning, use the
PlaySound("MouseClick", NULL, SND_SYNC);
If the specified registry entry or the waveform-audio file it identifies does
not exist, or if the file does not fit into the available memory, PlaySound
plays the default system sound.
The sound events that are predefined by the system can vary with the platform.
The following list gives the sound events that are defined for all
implementations of the Win32 API:
If an application registers its own sound events, the user can configure the
sound event by using the standard Control Panel interface. The application
should register the sound event by using the standard registry functions; for more
information, see Registry. The entries belong at the same position in the registry hierarchy as the
rest of the sound events. This position varies with the Win32 implementation. The
appropriate data value also varies with the implementation.
function always searches the registry for a keyname matching lpszSound
before attempting to load a file with this name. The PlaySound
function accepts flags that specify the location of the sound.
