The class is abstract and cannot be instantiated.
Try CDesCArrayFlat instead;

   CDesC16Array* array = new (ELeave) CDesCArray(5 ); //here gives the error message

   CleanupStack::PushL(array);
   array->AppendL(_L("1\tItem1"));
   array->AppendL(_L("2\tItem2"));
   array->AppendL(_L("3\tItem3"));
   array->AppendL(_L("4\tItem4"));

>now i want to know how can i go in "Item 1"(one of ListBox item) by pressing ok

Code:

/**
* Called by the framework whenever a list event occurs for which this container
* is an observer.
* @param aListBoxEvent The type of event which occured
*
*/
void CMyContainer::HandleListBoxEventL(CEikListBox* /*aListBox*/, TListBoxEvent aListBoxEvent)
{

// if the Select Key has been pressed
if ((aListBoxEvent == MEikListBoxObserver::EEventEnterKeyPressed) || (aListBoxEvent == MEikListBoxObserver::EEventItemClicked)) {
if (iMyListBox) {
// Do something with ...
//...((*iMyList)[iMyListBox->CurrentItemIndex()]);
}
}
}
}

regards;

Code:

TKeyResponse mycontainer::OfferKeyEventL(const TKeyEvent& aKeyEvent, TEventCode aType)
{
return iListBox->OfferKeyEventL(aKeyEvent, aType);
}

and don't forget to set focus to your listbox in ConstructL

You won't learn if you expect people to post the exact snippet of code that you require.

unfortunately, most of newbies just want the sources :\

Look how the OfferKeyEventL function is managed in a listbox example code.

I think you forgot to forward the keyevents to your listbox in your offerkeyevent function.
