A project I am working on requires that the computer make a sound.

This is a service written in VB.NET. Due to the location and circumstances of where this computer will be in use, e-mail or other notifications won't work in the case of something going wrong (the computer won't be on a network).

The service needs a way to alert people that something is wrong, so sound seemed like the logical choice.

A call to System.Console.Beep does not work when the program is running as a service. I also found this article that looks like the same problem I am having, but the link it contains on how to use something called "IOCTL_BEEP_SET" is broken, and quite a bit of Googleing has failed to yield any answers.

Does anyone out there know how to make a Windows Service (written in VB.NET) Beep? Or, know of a way for a computer to get someones attention other than sound? (system would be not logged in, and screen would likely be turned off, and is not on a network)

Thanks

    Wire a siren in to a com port. Better still add a bit of hardware so it will howl if there's no signal. If you are going to go this far, might as well do the job properly. – Tony Hopkinson Nov 23 '12 at 14:14

I think your service no interact with desktop.goto service property and set manually it. enter image description here

Try it :)

Then Try 

Console.Beep();
