Hi there,

I want to mute the key-clicks on a Windows CE device programmatically.
I didn't find any appropriate API in coredll.dll that does this. Does
anybody has any ideas on how I can do this?

I am working on a C# application on CF 2.0 for Windows CE 5.0 device.

Thanks,
Krupa
 
I realised that I need to change registry settings under
[HKEY_CURRENT_USER\ControlPanel\Volume] to achieve this. But I didnt
find any byte in the Mute key that mutes the Key Clicks setting.
However, I see the Key Clicks option in Control Panel->Volume. How is
it that I find no entry in the registry for this?

Any thoughts?
 
Set the Control Panel option one way and export the registry using Remote
Registry Editor. Change the option via the Control Panel to the other state
and export the registry to a second file. Compare the files. The
differences are the registry entries to turn off key clicks.

Thanks Paul!! I tried what you said and found that the registry
settings are the same in both scenarios.
Any thoughts?

After changing the registry values, you must then call the
AudioUpdateFromRegistry() API.

I think registry changes are fairly lazily written. Did you try a soft reset
after the change.
