Beep from PC speaker

[Hai Ly Hoang]

Hi,
I want to make a beep from PC speaker (like C++ beep(), not a beep from
sound-card).
How to do that ?
Thanks

[System.Runtime.InteropServices.DllImport("kernel32 .dll")]
private static extern bool Beep( int freq, int dur );

Beep(500,1000);

using System.Runtime.InteropServices;

[DllImport("KERNEL32.DLL",
EntryPoint="Beep",SetLastError=true,CharSet=CharSe t.Unicode,
ExactSpelling=true,CallingConvention=CallingConven tion.StdCall)]

public static extern bool Beep(int x,int y);

//you code

Beep(500,1000); //500 and 1000 are number of pitch, and duration
