完全可以把上面的代码分成两个部分来实现选择接入点和建立连接的分离。即建立连接的代码如下：

// IAP Selected，根据选择的接入点进行连接

// Open socket server and start the connection

User::LeaveIfError(iSocketServ.Connect());

User::LeaveIfError(iConnection.Open(iSocketServ));

// Now we have the iap Id. Use it to connect for the connection

TCommDbConnPref connectPref;

// Setup preferences

connectPref.SetDialogPreference(ECommDbDialogPrefPrompt);

// Sets the CommDb ID of the IAP to use for this connection

connectPref.SetIapId(iSelectedIap);

// Start connection

User::LeaveIfError(iConnection.Start(connectPref));

MTM方式下屏蔽系统接入点的做法

TImIAPChoice apChoice;

apChoice.iIAP = 0; // //store IAP id

apChoice.iDialogPref = ECommDbDialogPrefDoNotPrompt;//prompt dialog

CImIAPPreferences* apPref = CImIAPPreferences::NewLC();

apPref->AddIAPL(apChoice);

mailAccount->SavePopIapSettingsL(popAccount,*apPref);

CleanupStack::PopAndDestroy(apPref);

void GetCMWAPID()

{

iCmwapId = 0;

CCommsDatabase* commDb = CCommsDatabase::NewL(EDatabaseTypeIAP);

CleanupStack::PushL(commDb);

commDb->BeginTransaction();

CCommsDbTableView* commView = commDb->OpenTableLC( TPtrC( OUTGOING_GPRS ) );

TInt ret = commView->GotoFirstRecord();

TBool find = EFalse;

while( ret == KErrNone )

{

TBuf8<50> name;

commView->ReadTextL( TPtrC(GPRS_APN), name );

TRAPD(leaveCode,commView->ReadUintL( TPtrC( COMMDB_ID), iCmwapId ) );

if( name.CompareF(_L8("CMWAP") ) == 0 )
