Console.Beep Method

Updated: April 2009

Plays the sound of a beep through the console speaker.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
<HostProtectionAttribute(SecurityAction.LinkDemand, UI := True)> _
Public Shared Sub Beep
'Usage
Console.Beep()

ExceptionCondition
HostProtectionException

This method was executed on a server, such as SQL Server, that does not permit access to a user interface.

NoteNote:

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

By default, the beep plays at a frequency of 800 hertz for a duration of 200 milliseconds.

NoteNote:

   The Beep method is not supported on the 64-bit editions of Windows Vista and Windows XP.

The following example demonstrates the Beep method. The example accepts a number from 1 through 9 as a command line argument, and plays the beep that number of times.

      AndAlso (Int32.TryParse(args(0), x) = True) _
      AndAlso ((x >= 1) AndAlso (x <= 9)) Then 
         For i = 1 To x
