'Method 1:

'This code uses the Playsound API function. Playsound can read files from standard WAV files on
'disk, by reference from the system registry, or from a resource file. For the application
'developer, this means that you can create a registry entry for your sound effects, which means
'that the end user can use the control panel to customize their preferences in sounds. You avoid
'designing another configuration screen or panel, and the user can still customize the application.

'lpszName points to a registry entry

'specified sound has played.  Do not
'use with SND_ASYNC
