hello all.

i want to make a script which will play sounds when charger is connected or disconnected.

below is the code whic works only on script start

$bsound = _BatteryQueryEx()

Switch $bsound[0]
Case 0
SoundPlay(@WindowsDir & "mediatada.wav", 1)
Case 1
SoundPlay(@WindowsDir & "mediading.wav", 1)
EndSwitch
 

after that is udf code.

how i can to make it to monitor status and if charger wil disconnect it'll play a sound.

thanks

Undefined function -> _BatteryQueryEx()

You need to download the >UDF from the forum.

i have an udf i didn't paste the whole code.

scripts works but only if you run script, but aftr that connecting disconnecting cable doesn't give efect

this is whole code.

$batt = _BatteryQueryEx()

Switch $batt[0]
Case 0
SoundPlay(@WindowsDir & "mediatada.wav", 1)
Case 1
SoundPlay(@WindowsDir & "mediading.wav", 1)
EndSwitch

You'll need to save the initial state into a variable then loop the code until that state changes. Save the new state.

That's the loop.

[beqa 0]

can you show a sample?

[JohnOne 1,598]

$batt = _BatteryQueryEx()

$State = $batt[0]

While 3
    ;loop here
    ;$batt = _BatteryQueryEx()
    ;If $batt[0] changes set $State to $batt[0] and play appropriate sound
    ;add a sleep
WEnd

[beqa 0]

While 1
Switch $batt[0]
Case 0
SoundPlay(@WindowsDir & "mediatada.wav", 1)
Case 1
SoundPlay(@WindowsDir & "mediading.wav", 1)
EndSwitch
sleep(10)
WEnd

 

is it right?

[JohnOne 1,598]

Almost.

You have to test $batt[0] against $State and only play sound if it changes.

As it stands that will continue to play the sound.

[beqa 0]

and can't understand what is going

$batt = _BatteryQueryEx()
$state = $batt[0]

While 1
if $batt[0]=0 then
$state=0
elif batt[0]=1 then
$state=1
endif
sleep(10)
wend
Switch $state
Case 0
SoundPlay(@WindowsDir & "mediatada.wav", 1)
Case 1
SoundPlay(@WindowsDir & "mediading.wav", 1)
EndSwitch

Just ask yourself a question: Where in the loop am I updating $batt ?

[JohnOne 1,598]

Try this.

$batt = _BatteryQueryEx()
$state = $batt[0]

While 1
    $batt = _BatteryQueryEx()
    If $batt[0] <> $state Then
        $state = $batt[0]
        Switch $state
            Case 0
                SoundPlay(@WindowsDir & "\media\tada.wav", 1)
            Case 1
                SoundPlay(@WindowsDir & "\media\ding.wav", 1)
        EndSwitch

    EndIf
    Sleep(10)
WEnd

thanks, it works.

sorry, missed var in the loop.

[JohnOne 1,598]

Ace.

I'd recommend a longer sleep, maybe 1000.

[beqa 0]

for not drain cpu?

[JohnOne 1,598]

In my world, 1 second is enough to test such a thing, I'm a minimalist.
