read message only in inbox

Hi, I have a problem:
I have a sony p800 and I must read your message, but only message present in inbox, not message present in "Beamed", How to?

I use this method for read all:

TMsvId* entryId;
// entry id from the session event
entryId = static_cast<TMsvId*>(aArg2);
// new entry has been created in Inbox folder
if (*entryId == KMsvGlobalInBoxIndexEntryId )
{
// We take the created entries into a selection
CMsvEntrySelection* entries = static_cast<CMsvEntrySelection*>(aArg1);
for(TInt i = 0; i < entries->Count(); i++)
{
//action of code
}

Thanks a lot
Silvia
