Read IAPIDs without a view

[vinp]

Hello list,

I am referring to the following link, which has code for reading all the IAPs in a device:
http://wiki.forum.nokia.com/index.ph...rom_the_device
But in the code, a CCommsDbTableView is used to display the IAPs.

I am right now facing an issue, wherein I get a System Error -28 when I launch my application on the emulator. There is a similar issue in the following link
http://discussion.forum.nokia.com/fo...ror-%28-28-%29
I need to pass a valid IAPID while invoking the NewL() method of CSIPConnection class.

How can I retrieve an IAPID from the system, possibly the default IAPID, without having to use a view to display it to the user?

TIA
Vin

Hi Vnp,

You can read default IAP by use of CMDBSession and CCDConnectionPrefsRecord.
CCDConnectionPrefsRecord has member variable iDefaultIAP which give you a default IAP..

Hope, It'll help you

Hi,

Thanks a lot for the suggestion. Is there some sample code? Especially, I would like to know the sequence of iniitializations before accessing the default IAP as you have mentioned.
TIA

Go through below mentioned code:

TInt iap = KErrNotFound;
CMDBSession* dbSession = CMDBSession::NewL(CMDBSession::LatestVersion());
CleanupStack::PushL(dbSession);
CCDConnectionPrefsRecord *connPrefRecord =
static_cast<CCDConnectionPrefsRecord*> (CCDRecordBase::RecordFactoryL(
KCDTIdConnectionPrefsRecord));
CleanupStack::PushL(connPrefRecord);

// Set the direction of connection
connPrefRecord->iDirection = ECommDbConnectionDirectionOutgoing;
connPrefRecord->iRanking = 1;
if (connPrefRecord->FindL(*dbSession))
iap = TInt(connPrefRecord->iDefaultIAP);

CleanupStack::PopAndDestroy(2, dbSession);

[vinp]

if (connPrefRecord->FindL(*dbSession))
I could not find the mention of the method FindL() in the documentation for the CCDConnectionPerfsRcord or CCDRecordBase.
Could you please clarify from which parent this method is inherited?

TIA

Also, what are the header files that I should include for the definiton of CMDBSession and CCDConnectionPrefsRecord?
As per the documentation, I should #include <CommsDatTypesV1_1.h> to access the definition of CCDConnectionPerfsRecord and link against commsdat.lib.
But even after including this header file, I get an undefined identifier error for CCDConnectionPerfsRecord variable.

TIA

Add below mentioned of line...

#include <metadatabase.h>
#include <commsdattypesv1_1.h>
using namespace CommsDat;

TInt iap = KErrNotFound;
CMDBSession* dbSession = CMDBSession::NewL(CMDBSession::LatestVersion());
CleanupStack::PushL(dbSession);
CCDConnectionPrefsRecord *connPrefRecord =
static_cast<CCDConnectionPrefsRecord*> (CCDRecordBase::RecordFactoryL(
KCDTIdConnectionPrefsRecord));
CleanupStack::PushL(connPrefRecord);

// Set the direction of connection
connPrefRecord->iDirection = ECommDbConnectionDirectionOutgoing;
connPrefRecord->iRanking = 1;
if (connPrefRecord->FindL(*dbSession))
iap = TInt(connPrefRecord->iDefaultIAP);

CleanupStack::PopAndDestroy(2, dbSession);

[vinp]

Thanks. That worked.

I get a KERNEXEC-3 for the following line:
connPrefRecord->iRanking = 1;
But there is no issue with the preceding line:
connPrefRecord->iDirection = ECommDbConnectionDirectionOutgoing;

Am I missing something?
TIA

I had used
CCDConnectionPrefsRecord *connPrefRecord =
static_cast<CCDConnectionPrefsRecord*> (new (ELeave) CCDRecordBase(KCDTIdConnectionPrefsRecord));
instead of what you had suggested:
CCDConnectionPrefsRecord *connPrefRecord =
static_cast<CCDConnectionPrefsRecord*> (CCDRecordBase::RecordFactoryL(
KCDTIdConnectionPrefsRecord));

I thought there should not be any difference. I reverted to your suggestion and the problem disappeared.
