MessageBeep and System speaker

[Johnny Van Bavegem]

I am using a windows xp embedded device for about 4 months now.
At this point the end users let me know that they never hear a beep
when some application gives an error. The same application running on
a XP prof is beeping for some errors.
I detected that in this application the function MessageBeep has been
used.
I do not have a sound card but only a system speaker in my hardware.
So can somebody tell me what components I must implement to let the
the
system speaker beep with the MessageBeep function ?

Thanks in advance.

Johnny Van Bavegem,

Start with "Beep Driver" from "Software : System : System Services : Base"
(make sure your min visibility level is less or equal 200 to see the
component).
There is also "System speaker" under "Hardware : Devices : System devices"
you may be interested in.

I have already the "Beep driver" and the "System speaker" in my configuration
Somebody told me that it has something to do with the "XP Sound scheme" an
the "Sound Control panel". Is this correct ? Because I already tried it with and
without those components.

Johnny Van Bavegem,

"XP Sound Scheme" will bring system wav files and proper registry settings to assign the wav's to proper application/system evetns.
You may want to try it out on the target device. Just go to Control Panel, "Sounds and Audio Devices Properties" and on the "Sounds"
page select "Windows Default" sound scheme.
In case you don't have the Control Panel or particular applet and you can't re-deploy the image now. You may just transfer the wav
files and the registry settings from the "XP Sound Scheme" component resources on to your device.

Sorry, couldn't be of much help here.
