Problem with GPRS connection

[ivanyyf]

i was doing an application on create a GPRS IPA and access , but i met a problem which was I could create the IPA while i cant access with my application. however, I can surf the GPRS on web function of the phone with my IAP . here is some part of my code : anyone can help me ?

User::WaitForRequest(iStatus);

User::WaitForRequest(status);
CleanupStack::PopAndDestroy(); // overrides



}
void CSocketsEngine::InitConnection()

if (netAgent.Open() == KErrNone)

view = db->OpenConnectionPrefTableViewOnRankLC(ECommDbConnectionDirectionOutgoing,1);

view->GotoFirstRecord();

view->UpdateDialogPrefL(ECommDbDialogPrefDoNotPrompt);
TRequestStatus status;
netAgent.StartOutgoing(status);
User::WaitForRequest(status);
CleanupStack::PopAndDestroy(3); // view, db, netAgent
}
then is the common void connectL();


anybody can give me some suggestion?

[ivanyyf]

it seems what i had created was a WAP IAP for connection, not a GPRS connection. WAP can only surf the net, but can not connect to server to retrive data. So any idea abt to change this code to set up a GPRS IAP for sending and receiving data some a server?

Hi
is it possible to try this GPRS connection on the emulator?
