Overview
This snippet shows a simple function implementation to export one contact from the default contacts database as a vCard to a given file.
This snippet can be self-signed.
MMP file
The following capabilities and libraries are required:
CAPABILITY ReadUserData
LIBRARY euser.lib
LIBRARY estor.lib
LIBRARY efsrv.lib
LIBRARY cntmodel.lib
Source file
#include <e32cmn.h> //TUid
#include <e32std.h> //User
#include <e32base.h> //CArrayPtr, CleanupStack
#include <e32def.h> //TBool
#include <s32file.h> //RFileReadStream
#include <f32file.h> //RFs
#include <cntdb.h> //CContactDatabase
#include <cntdef.h> //CContactIdArray
#include <cntfilt.h> //CCntFilter
TBool ExportVCardL(const TDesC& aFileName, TInt aItemIndex)
{
RFs fileSession;
RFile file;
User::LeaveIfError(fileSession.Connect());
CleanupClosePushL(fileSession);
if (file.Replace(fileSession, aFileName, EFileWrite) != KErrNone)
{
//failed to create the file
CleanupStack::PopAndDestroy(); //fileSession
return EFalse;
}
CleanupClosePushL(file);
//open a write stream to the file
RFileWriteStream outputFileStream(file);
CleanupClosePushL(outputFileStream);
//open the default contacts database
CContactDatabase* contactsDb = CContactDatabase::OpenL();
CleanupStack::PushL(contactsDb);
//create an array of contact IDs to export
CContactIdArray* exportContacts = CContactIdArray::NewL();
CleanupStack::PushL(exportContacts);
//use a filter to get only contact items (e.g. templates are excluded)
CCntFilter *filter = CCntFilter::NewLC();
filter->SetContactFilterTypeALL(EFalse);
filter->SetContactFilterTypeCard(ETrue);
contactsDb->FilterDatabaseL(*filter);
//create an array to hold all filtered contact items
CContactIdArray* contactIds;
contactIds = CContactIdArray::NewLC(filter->iIds);
//add given contact(by index) to the array of contact IDs to export
if((*contactIds).Count() >= aItemIndex)
exportContacts->AddL((*contactIds)[aItemIndex] );
CleanupStack::PopAndDestroy(2); //contactIds, filter
//KVersitEntityUidVCard is used to identify a vCard
TUid uid = TUid::Uid(KVersitEntityUidVCard);
contactsDb->ExportSelectedContactsL(uid,
*exportContacts,
outputFileStream,
//contact ID is no exported
CContactDatabase::EExcludeUid);
CleanupStack::PopAndDestroy(5); //exportContacts,contactsDb,
//outputFileStream,file,fileSession
return ETrue;
}
Postconditions
A contact given by the index from the default contacts database is exported as a vCard to the given file.
The function returns ETrue to the caller when the file creation succeeds or EFalse when the file creation fails.
