The dbicButton control supports the playing of sound files (.wav format) in response to the Click and MouseOver events of the control. To implement custom sounds for these events set the SoundClick and/or SoundOver properties of the control in the design-time property inspector or in code at runtime.
Example:
VB.NET
Me.dbicButton1.SoundOver = "C:\Help.wav"
C#
this.dbicButton1.SoundOver = "C:\Help.wav"
