Remember last volume

[ajit]

Hi,

I am using windows media player object for my audio player.

I need my player to remember the last set volume on the player if possible.

I can use an INI file to store the last audio volume but i do not know how to get the current volume to store it on exiting the window.

Any help would be appreciated.

Regards Ajit

Ill show u what i got on mine:

Start of script

$Vol2 = IniRead($iFile, 'Volume', 'Vol', '')
If $Vol2 = '' Then
    $Vol = 100
Else
    $Vol = $Vol2
EndIf
GUICtrlSetData($Slider2, $Vol)

On a continuous loop

;=============================================================================
$Vol2 = IniRead($iFile, 'Volume', 'Vol', 'default')
$Vol = GUICtrlRead($Slider2, 1)
SoundSetWaveVolume($Vol)
GUICtrlSetData($InfoVol, $Vol & '%')
;=============================================================================
If $Vol <> $Vol2 Then
IniWrite($iFile, 'Volume', 'Vol', $Vol)
EndIf
;=============================================================================

get it?

@careca,

Thanks for your reply.

But I don't see any way to write data to an INI file unless I have the current volume of the player to be able to use to write the INI data.

My problem is I cannot obtain the current volume in any readable form.

Thanks and regards

I guess that is not possible

[careca]

hmmm, and i guess you don't understand the code.

$Vol2 = IniRead($iFile, 'Volume', 'Vol', 'default') ;<<<<< Read the value from the ini file 0-100
$Vol = GUICtrlRead($Slider2, 1) ;<<<<< Read slider position, and retrieve value 0-100
SoundSetWaveVolume($Vol) ;<<<<< Use the previous value to set volume
If $Vol <> $Vol2 Then ;<<<<If vol is different from vol2, means the value written on file is different, from the one on the slider
IniWrite($iFile, 'Volume', 'Vol', $Vol) ;<<<< so we write the correct/updated value
EndIf

Get it?

Thanks for your response.

Would you mind integrating your code into mine.

My problem is I have NO slider (nor do i intend to use one) so question of GUICtrlRead does not arise.

I want to use slider of 'Media Player Object' whose reading i cannot get.

Thanks and regards,

Ajit

Hi, im sorry, i don't understand anything about objects, your code here only shows a black box and a fileopen dialog...

@careca,

I guess problem with OS. I am on XP Professional, Service Pack 3
