Number of message IDs

[freaky_911]

Hi!

Can somebody tell me how many message IDs are produced in
the Inbox of my Symbian 3rd ed. phone??? I think that those IDs are unique but they are used again when I delete a message from my inbox. Is this correct???

The number of ID has to be connected to the available space in
the phone is that right?? Does somebody know some concrete data?

Kind regards!

Hello,

As far as I know there is no limit to the number of IDs that can be produced in the inbox, other than the obvious one: the maximum number of messages that fit in the device's memory.
As for the IDs, yes they are unique. I had 5 messages in my inbox and the function sms_messages() returned 5 different IDs. Then I deleted message 3, and got the IDs accordingly (1, 2, 4 and 5). Then I saved another message to my inbox and got a different (as in not used before) ID, but that may depend on which device is being used. I'm not sure.

Hope I understood your questions

hi freaky_911
bogdan is absolutely correct that there is no limit to generate the ID for the message.
and its also correct that one the message is deleted the ID is used again.
hope you are satisfied.
thanx

Hmmm ok thank you very much!
I think you mean "is not used again" =) in the following sentence. Do you?

and its also correct that one the message is deleted the ID is used again.

But no problem - thanks a lot for your answers!!!

Hmmm sorry for asking again but I think that the IDs
have to be repeated when the maximum is reached.

If the phones memory is full and I delete one message
so that a new one can arrive what messageID does it
get?? It cannot get an ID of an other existing message
in the Inbox but if the ID is always increasing it has
to reach the absolute maximum after a time and that causes
an error or the ID will start with zero again..... does it???

Sorry for asking but I would like to rebuild my programm
based on the IDs of messages...

Kind regards!

From memory, not verified:

ID keeps growing with increments of "1" until max in reached. Then it wraps back to start. Next new message gets next highest free ID number. Old freed numbers are not reused ever, ID just keeps growing. Zero is special and not used for normal messages.

Btw the max number is so high, you switch to new phone before reaching it.

hey guys can u tell me how to get the unique message IDs?

CMsvEntry* folderInboxContext = CMsvEntry::NewL(*iSession, KMsvGlobalInBoxIndexEntryId, sort);
CleanupStack::PushL(folderInboxContext);

CMsvEntrySelection* InboxEntries = folderInboxContext->ChildrenL();
CleanupStack::PushL( InboxEntries );
CMsvEntry* entry = iSession->GetEntryL( (*InboxEntries)[i] );
CleanupStack::PushL(entry);

TMsvEntry entry1 = entry->Entry();



i've tried using entry1.Id();
as well as entry->EntryId();

am i using it correctly?

they seem to be unique numbers but somehow when i recv a new message all IDs are automatically changed and now the ID for my previous latest message bcome the ID for my latest message,

e.G:
SMS2 ID=1048584 latest
SMS1 ID=1048585

let say i get a new message SMS3, now all the IDs changed,

SMS3 ID=1048584
SMS2 ID=1048585
SMS1 ID=1048598

please help
