Add this to your header file:
class TIapData { public: TBuf<128> iName; TUint32 iIap; };
These are the additional headers files required:
#include// CAknSinglePopupMenuStyleListBox #include#include // CCommsDatabase
TInt SelectIAPL() { CArrayFixFlat* iEApList=new (ELeave) CArrayFixFlat (2) ; TInt stack=0; // Make listitems. and PUSH it CAknSinglePopupMenuStyleListBox* list = new(ELeave) CAknSinglePopupMenuStyleListBox; CleanupStack::PushL(list);stack++; // Create popup list and PUSH it.

CTextListBoxModel* model = list->Model(); model->SetItemTextArray(items); model->SetOwnershipType(ELbmOwnsItemArray); CleanupStack::Pop(); popupList->SetTitleL(_L("IAP")); list->SetListBoxObserver(popupList); TInt popupOk = popupList->ExecuteLD(); CleanupStack::Pop(); TInt iap=0; if (popupOk) { TInt index = list->CurrentItemIndex(); iap=(*iEApList)[index].iIap; } CleanupStack::PopAndDestroy(); iEApList->Reset(); delete iEApList; return iap; }
The following code reads all access points from the device disregarding their type. This is preferred unless there is some grave reason why you would force the user to select e.g. from GPRS connections.
TFileName iapName; TUint32 iapID; TInt err; // open the IAP communications database CCommsDatabase* commDB = CCommsDatabase::NewL(); CleanupStack::PushL(commDB); // Open the IAP table CCommsDbTableView* view = commDB->OpenTableLC(TPtrC(IAP)); // Point to the first entry if (view->GotoFirstRecord() == KErrNone) { do { view->ReadTextL(TPtrC(COMMDB_NAME), iapName); view->ReadUintL(TPtrC(COMMDB_ID), iapID); // Store name and ID to where you want to } while (err = view->GotoNextRecord(), err == KErrNone); } CleanupStack::PopAndDestroy(); // view CleanupStack::PopAndDestroy(); // commDB
Following code sample shows how to retrieve all set GPRS or CSD internet access point from the device.
CCommsDatabase* commDb = CCommsDatabase::NewL(EDatabaseTypeIAP); CleanupStack::PushL(commDb); CCommsDbTableView* commView = commDb->OpenIAPTableViewMatchingBearerSetLC( ECommDbBearerCSD|ECommDbBearerGPRS, ECommDbConnectionDirectionOutgoing); TFileName TmpName; if (commView->GotoFirstRecord() == KErrNone) { do { TmpName.Zero(); commView->ReadTextL(TPtrC(COMMDB_NAME),TmpName); // Add TmpName to CDesCArray for example // it has the IAP's human readable name TUint32 IapNum; commView->ReadUintL(TPtrC(COMMDB_ID),IapNum); // Add IapNum into other array, // it has the ID for the accesspoint used with connection }while (commView->GotoNextRecord() == KErrNone); } CleanupStack::PopAndDestroy(2);//commView,commDb
With the code the TmpName variable will held the internet access point name you could show to user for selection, and the IapNum variable holds the internet access point identifier you could then use with the RConnection when making a silent connection. Note that when making a silent connection you also need to call the SetDialogPreference()-function with ECommDbDialogPrefDoNotPrompt for the connection preferences (TCommDbConnPref).
The code below shows how to retrieve proxy server name and the port number from a certain IAP.
// // The tableView variable here is the instance of CCommsDbTableView // Normally you call CCommsDatabase::OpenTableLC() to get the instance of // CCommsDbTableView. // (See also the other examples above.) // // Firstly, we need to get the IAPService and IAPServiceType // of our IAP in order to find out the proxy information. TUint32 iapService; HBufC* iapServiceType; tableView->ReadUintL(TPtrC(IAP_SERVICE), iapService); iapServiceType = tableView->ReadLongTextLC(TPtrC(IAP_SERVICE_TYPE)); // Check whether this IAP uses proxy or not. TBool isProxyEnabled = EFalse; CCommsDbTableView* proxyTableView = commsDb->OpenViewOnProxyRecordLC( iapService, *iapServiceType); if (KErrNone == proxyTableView->GotoFirstRecord()) { proxyTableView->ReadBoolL(TPtrC(PROXY_USE_PROXY_SERVER), isProxyEnabled); // If proxy is enabled then do something. if (isProxyEnabled) { proxyServerName = proxyTableView->ReadLongTextLC(TPtrC(PROXY_SERVER_NAME)); proxyTableView->ReadUintL(TPtrC(PROXY_PORT_NUMBER), proxyPortNumber); // Do whatever you want with proxyServerName and proxyPortNumber. CleanupStack::PopAndDestroy(proxyServerName); } }
