Funny SetSysPref

A PocketC native palm library offering native forms and assorted utilities

Ok, here's another funnyity.

I don't want any sound when a button is pressed because I have my own sounds.

So I say SetSysPref(30,0); It does not work though. I go to the system preferences and see that the value has been changed to 'off'.

Now the remarkable happens: I change the system sound to 'high' and then to 'off' again. Go back to the applet and voil?ɬ†: no sound.

To summarise: SetSysPref seems to change the prefs, but it does not have the same effect as when it is done through the prefs programme.

Are there answers out there? Is the Emulator to blame?[:p]

The PalmOS doesn't check the for the values in the sound preference very often. From what I understand, only when the preferences application is used or when a soft reset occurs. Thus changing the sound preference values from within any appliation, pocketc or otherwise will not change current volume settings.

I would need to provide and entirely new function to get/set the current volume settings for this to work. I'll look into this for the next release.

BTW: Have you considered use the Vibrate() function in your app?

Ok, I see.

Vibrate(ing) would actually suit the application quite well, but I still have to find a PDA supporting the function to test it on. My own doesn't and I'm not going to buy one especially for vibrating.

A vibrating emulator just doesn't do it for me ...;)

you could try asking a kind soul to 'test' ur proggie on their vibrate-supporting PDA.

they need be very kind, because who knows what kind of crazy vibrate code u'll put in there... ;) or u could make a mistake, u know. :P

i gave u the idea, now do me a favour and don't pick on me. :)
