Dear friends,
I am displaying AVKON_SETTING_PAGES in Dialog

I do have the following problems
1.volume control
---------------------
a> the prog builds successfully but crashes when I start the program in emulator.
b>if I comment Out the initialisation of volume control in the CreateSettingItemL, it
runs fine.

HERE IS THE CODE
-------------------------------
AVKON_SETTING_ITEM
{
identifier=Etest3Volume;
setting_page_resource=r_test3_volumesetting;
name=qtn_test3_volume;
},

RESOURCE AVKON_SETTING_PAGE r_test3_volumesetting
{
number=8;
label=qtn_test3_volume;
type=EAknCtVolumeControl;
editor_resource_id=r_test3_volumesetting_volume;
}

RESOURCE VOLUME r_test3_volumesetting_volume
{
flags=ESettingsVolumeControl;
value=1;
}

CAknSettingItem* Ctest3avkonsettings::CreateSettingItemL(TInt aIdentifier)
{
CAknSettingItem* settingItem=NULL;
switch(aIdentifier)
{
case Etest3Volume:
settingItem=new (ELeave) CAknVolumeSettingItem(aIdentifier,iVolume);
break;
}
return settingItem;
}
