Hi all:
I spcified a TContactItemId, and how can I check the item with the Id exists in the current contact database?

Hi,

Try with this function FindLC() in CContactDatabase.
Also check CAknSearchField.

FindLC uses TDesC so is useless if you want to searc based on TContactItemId. A better solution would be to use SortedItemsL() or to create a LocaView....but this is an ugly solution

Did u try using:-

CContactItem* CContactDatabase::ReadContactL(TContactItemId aContactId);

It will give u what you are looking for.

Yeah, I took use of the leave code of OpenContactL to achieve that. thank you.

What if ReadContactL crash the application as if TContactItemId does not exist?

Is there any simple solution to find that the contact with TContactItemId exist?

Does it really "crash" (panics as we know), or does it simply leave? Try using TRAP/D.
Let us say, you have

void CSomething::YourMethodL(TContactItemId aId)
{
    CPbkContactItem *item=iSomething->ReadContactL(aId);
    CleanupStack::PushL(item);
    ... do things ...
    CleanupStack::PopAndDestroy(); // item
}

What happens if you modify it to

void CSomething::YourMethodL(TContactItemId aId)
{
TRAPD(err,
    CPbkContactItem *item=iSomething->ReadContactL(aId);
    CleanupStack::PushL(item);
    ... do things ...
    CleanupStack::PopAndDestroy(); // item
);
}

The problem was that I was using TRAPD with ReadContactLC() function. But It is not recommended to call a function with an LC suffix from inside a trap harness. Thats why I try it as following:

TRAPD(err, Citem = iDatabase->ReadContactLC((*contacts)[i]); CleanupStack::Pop(Citem));

The application started behaving very strange. The function in which I was using the above line was called again automatically.

Then I used ReadContactL() instead of ReadContactLC() and it solved the problem.

Thanks everyone for the contribution.
