Beeping

Getting a client to beep through ssh can be a very complicated task. Pragma FortressSSH’s Advanced Console and wrapper technology have allowed a system beep from a server application to pass to the client without any customization. Also with a slight modification an echo of beep to the console can also be passed.

Here is some sample code to beep from an application

VB

Imports System

Imports System.Threading

Imports System.Net

Imports System.Net.Sockets

Module Module1

Private welcomeMessage As String = "Welcome VBBeep"

Private Declare Function GetStdHandle Lib "kernel32" _

(ByVal nStdHandle As Long) As Long

Private Declare Function _

SetConsoleMode Lib "kernel32" _

            (ByVal hConsoleOutput As Long, _

ByVal dwMode As Long) As Long

Private Const ENABLE_PROCESSED_OUTPUT As Long = &H1

Private Const STD_OUTPUT_HANDLE As Long = -11&

Sub Main()

'   These are 3 ways to beep

Console.WriteLine(welcomeMessage)

 '   System beep calls with Advanced Console or Wrapper

Console.Beep(200, 300)

Console.Beep(500, 300)

Console.Beep(700, 300)

  '   Character 7 echo to console with Advanced Console or Wrapper

SetConsoleMode(GetStdHandle(STD_OUTPUT_HANDLE), Not (ENABLE_PROCESSED_OUTPUT))

Console.WriteLine(Chr(7))

Console.WriteLine("Beeped")

End Sub

End Module

In VC:

#include <stdio.h>

#include <windows.h>

void main( int argc, char **argv )

{

      DWORD Mode;

      HANDLE      hOutput = GetStdHandle(STD_OUTPUT_HANDLE);

// System beep calls with Advanced Console or Wrapper

Beep(2128,12);

Beep(1824,4);

Beep(2128,12);

// Character 7 echo to console with Advanced Console or Wrapper

GetConsoleMode( hOutput, &Mode );

      Mode &= ~ENABLE_PROCESSED_OUTPUT;

SetConsoleMode( hOutput, Mode );

putchar(7);

printf("%c",7);

putchar(7);

printf("%c",7);

putchar(7);

printf("%c",7);

}
