PlaySoundPackage

A simple visual component to play WAVe files in Windows or Linux Aimed at developers that want a simple crosscompile from Windows to Linux and vice versa without having to use complicated libraries or dll/o files. Debug Logging available. (Set DebugMode=TRUE) The Wav file can be an embedded resource: 1. Open Project Options/Resources 2. Click Add (+ sign) 3. In the FileOpen dialog, set the filter to All Files(*) 4. Add you Wav sound file. It will automatically be saved as type RCDATA 5 Rinse and Repeat OR The Wave files can be in a res file that you include in the initialisation section OR The wave file can be distributed with your executable (worst option!) Everything the same for Windows or Linux (and possibly Mac?)
