Public Shared Sub Beep

Exception Condition
HostProtectionException

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

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

System_CAPS_noteNote

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

Beep wraps a call to the Windows Beep function. Whether Beep produces a sound on versions of Windows before Windows 7 depends on the presence of a 8254 programmable interval timer chip. Starting with Windows 7, it depends on the default sound device.

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.

' This example demonstrates the Console.Beep() method.
