To convert read contact details into CDesCArrayFlat

[abhinavnishantintg]

Hi,
I need to raed contacts from phone and show in a list box. I have code to read contacts. list box is ready. need to convert read contactdetails ContactItem* to CDesCArrayFlat
I have the following code which is called from AppUi::handleCommandl()
CContactDatabase* contactsDb = CContactDatabase::OpenL();
CleanupStack::PushL(contactsDb);
// Get the ID of the own card and open the contact:
TContactItemId ownCardId = contactsDb->OwnCardId();
if (ownCardId == KNullContactId )
User::Leave(KNullContactId );
//Own card may not be set
CContactItem* ownCard = contactsDb->ReadContactL(ownCardId);
CleanupStack::PushL(ownCard);
TInt count = ownCard->CardFields().Count();
contactsDb->CloseContactL(ownCard->Id());
CleanupStack::PopAndDestroy(2); // ownCard, contactsDb



CDesCArray* array = new (ELeave) CDesCArrayFlat(3);
iSearchList->MakeVisible(EFalse);
//iDetailedView = ETrue;
iSearchList->Model()->SetItemTextArray(array);
iSearchList->MakeVisible(ETrue);
iSearchList->SetCurrentItemIndexAndDraw(0);
SizeChanged();
iSearchList->ActivateL();


following code in AppView->constructL()
CreateWindowL();

iFont = AknLayoutUtils::FontFromId(EAknLogicalFontSecondaryFont);

iSearchList = new (ELeave) CAknSingleStyleListBox();
iSearchList->ConstructL(this);
iSearchList->SetContainerWindowL(*this);
iSearchList->CreateScrollBarFrameL(ETrue);
iSearchList->ScrollBarFrame()->SetScrollBarVisibilityL(
CEikScrollBarFrame::EOn,
CEikScrollBarFrame::EAuto);

iItemList = new (ELeave) CDesCArrayFlat(3);
iSearchList->Model()->SetItemTextArray(iItemList);
iSearchList->Model()->SetOwnershipType(ELbmDoesNotOwnItemArray);

iDetailList = new (ELeave) CAknFormDoubleStyleListBox;
iDetailList->ConstructL(this);
iDetailList->SetContainerWindowL(*this);
iDetailList->CreateScrollBarFrameL(ETrue);
iDetailList->ScrollBarFrame()->SetScrollBarVisibilityL(
CEikScrollBarFrame::EOn,
CEikScrollBarFrame::EAuto);
iDetailList->Model()->SetOwnershipType(ELbmOwnsItemArray);
iDetailList->MakeVisible(EFalse);
iSearchList->MakeVisible(ETrue); // show "no results" at startup
iSearchList->SetListBoxObserver(this);
SetRect(aRect);
ActivateL();
MakeVisible(ETrue);


following code in appview::draw()
CWindowGc& gc = SystemGc();

gc.SetPenStyle( CGraphicsContext::ENullPen );
gc.SetBrushColor( KRgbWhite );
gc.SetBrushStyle( CGraphicsContext::ESolidBrush );
gc.DrawRect( aRect );

gc.UseFont(iFont);
TInt lineHeight = iFont->HeightInPixels()+1;

const TInt col = 5;
gc.DrawText(KAboutString1, TPoint(col, lineHeight));
gc.DrawText(KAboutString2, TPoint(col, lineHeight*2));
gc.DrawText(KAboutString3, TPoint(col, lineHeight*3));
gc.DrawText(KAboutString4, TPoint(col, lineHeight*4));
gc.DrawText(KAboutString5, TPoint(col, lineHeight*5));

You may iterate through each contact & extract the required fields from it , store that in an array & then display them in listbox.

http://www.developer.nokia.com/Commu...fault_database

Above link may be a good reference to do so.The part of code in link, where field data is getting stored in the buffer 'wmobile', you may pass the CdesCArray instead & fill up the array with field elements

[abhinavnishantintg]

Hi,
The link suggests use of 3 fields workmobile number, home mobile number. There must be other fields also.What are those fields? How to extract them?Any pointer?

[symbianyucca]

you could check the API docs for other fields, here's one link to online docs: http://library.developer.nokia.com/i...ngs.guide.html

I got the link I was looking for->

using HandleDatabaseEventL(TContactDbObserverEvent aEvent), is there any way to know what changes invoked the function?

[wizard_hu_]

You can certainly get some details from that argument eEvent, but that is all.

using HandleDatabaseEventL(TContactDbObserverEvent aEvent),.(I get phone number that is added or edited, but not that is deleted). Do I need to take a backup of database to get deleted numbers details. If I have to take a backup of the database, can someone throw light on how to do that. or is there any other way?
from appui I am creating object of ContactsEngine. ContactEngine is derived from MContactDbObserver.

In constructl() of ContactEngine->
gConsole=((CPhoneAppUi *)(CEikonEnv::Static()->AppUi()))->gConsole2;
iContactDatabase = CContactDatabase::OpenL();
// Here iContactDatabaseObserver is a CContactDatabaseObserver pointer
//
CContactChangeNotifier* DatabaseNotifier = CContactChangeNotifier::NewL(*iContactDatabase , this);

in HandleDatabaseEventL( TContactDbObserverEvent aEvent )
_LIT(KConsoleMessageDisplay,"MessageDisplay");
_LIT(KConsoleEdit,"Edit");
_LIT(KConsoleAdd,"Add");
_LIT(KConsoleDelete,"Delete");
TContactItemId aChangeId=aEvent.iContactId;
CContactItem* ownCard = iContactDatabase->ReadContactL(aChangeId);
CleanupStack::PushL(ownCard);
TBuf<100> mobile(0);
CContactItemFieldSet &field_set = ownCard->CardFields();
for (TInt i = 0 ; i < field_set.Count() ; i++)
{
CContactItemField& field = field_set[i];
if (field.ContentType().ContainsFieldType(KUidContactFieldVCardMapCELL))
{
// This is general mobile processing. It will get all general mobiles in the contact list
mobile.Fill('\0',1);
mobile.Copy(field.TextStorage()->Text());
mobile.ZeroTerminate();
gConsole = Console::NewL(KConsoleMessageDisplay,TSize(20,20));
CleanupStack::PushL(gConsole);
gConsole->Printf(mobile);
gConsole->Getch();
CleanupStack::PopAndDestroy(gConsole);
//TBuf<100> abc(KTab);
//abc.Append(mobile);
//iItemList->AppendL(abc);
//process general mobile according to application logic
continue;
}
}
CleanupStack::PopAndDestroy();
TUint aConnInt=aEvent.iConnectionId;
switch(aEvent.iType)
{

//if any contact deleted in phonebook
case EContactDbObserverEventContactDeleted:
{
gConsole = Console::NewL(KConsoleMessageDisplay,TSize(20,20));
CleanupStack::PushL(gConsole);
gConsole->Printf(KConsoleDelete);
gConsole->Getch();
CleanupStack::PopAndDestroy(gConsole);
}
break;
//event if any contact changed
case EContactDbObserverEventContactChanged:
{
gConsole = Console::NewL(KConsoleMessageDisplay,TSize(20,20));
CleanupStack::PushL(gConsole);
gConsole->Printf(KConsoleEdit);
gConsole->Getch();
CleanupStack::PopAndDestroy(gConsole);
}
break;
//event if any new contact added to phonebook
case EContactDbObserverEventContactAdded:
{
gConsole = Console::NewL(KConsoleMessageDisplay,TSize(20,20));
CleanupStack::PushL(gConsole);
gConsole->Printf(KConsoleAdd);
gConsole->Getch();
CleanupStack::PopAndDestroy(gConsole);
}
break;
//check TContactDbObserverEventType for more events.
}

(It has been a while, sorry)

Yes, you need a shadow copy of the database because the event you get is a notification, it comes when the contact is deleted (and thus is inaccessible) already, the same applies if you want to track changes. An other noteworthy thing is that in case of mass deletion you get the event for a few dozens-hundreds items at most, so if you really want to know about all deleted items, you may want to use some timer for recognising a possible sequence deletion events, and compare the remaining database with your shadow copy at the end only.
