Problem of setting body text for MMS

[sophiachang]

Hi,

I set all information for MMS, including subject, phone #, body text, and attached image file. After I sent it out, in the outbox, I can't see body text, but other fields are fine. (I use emulator for test, due to capability, I not yet try it on the phone)

void CMessageSend_S60::CreateMMSL
(
TDesC16& aBodyText,
TDesC16& aSubject,
TDesC16& aAttachedFilename,
TDesC16& aPhonenum
)
{

// - CMsvEntry accesses and acts upon a particular Message Server entry.
// - NewL() does not create a new entry, but simply a new object to access an existing entry.
// - It takes in as parameters the client's message server session,
// ID of the entry to access and initial sorting order of the children of the entry.
CMsvEntry* theEntry = CMsvEntry::NewL
(
*iSession,
KMsvGlobalOutBoxIndexEntryId,
TMsvSelectionOrdering()
);
CleanupStack::PushL( theEntry );

// Set context to the parent folder (Outbox)
iMmsMtm->SwitchCurrentEntryL( theEntry->EntryId() );

// Create new message in the parent folder (Outbox) and set it as the current context.
iMmsMtm->CreateMessageL( iMmsMtm->DefaultServiceL() );

CleanupStack::PopAndDestroy(); // entry

// Set recipients
// use this to add the "To" recipients.
iMmsMtm->AddAddresseeL( aPhonenum );

// Set message subject
//iMmsMtm->SetSubjectL( aSubject );
iMmsMtm->SetSubjectL( aBodyText );


// Doesn't work, don't know why, so insert bodytext as attachment file
// Set body text
CRichText& richBodyText = iMmsMtm->Body();
richBodyText.Reset();
richBodyText.InsertL( KBodyTextStartPosition, aBodyText );



// Set attchment file, including image file
TRAP( err, SetAttachmentToMsgL( aAttachedFilename ) );

if( err != KErrNone )
{
User::Leave( err );
}

TMsvEntry theTMsvEntry = iMmsMtm->Entry().Entry();

// Set InPreparation to false
theTMsvEntry.SetInPreparation(EFalse);
// Mark as visible, after this the message can be seen in Outbox and,
// after sending, in Sent folder.
theTMsvEntry.SetVisible(ETrue);

// Commit changes
iMmsMtm->Entry().ChangeL(theTMsvEntry);
//Save the changes
iMmsMtm->SaveMessageL();


// Send Message
SendMessageL();
}

Does anyone know what the problem is?
Thanks in advance!

The MMS MTM does not make use of the default 'Body' member. Check 'mmssend' example of S60 2nd edition SDKs or the MtmsExample of the EMCC-book (download the samples from http://www.forum.nokia.com/main/plat...s60/books.html) for details.

You can achieve the same purpose by adding a text attachment.

Hi wizard_hu,

Got it! Thanks a lot!

I use CMmsClientMtm::CreateTextAttachmentL() to insert MMS body text instead of CMmsClientMtm::Body(), and it works fine.

After sending MMS out, I am watching the incoming MMS, and want to get the MMS body text. I use CMsvStore::HasBodyTextL() to check if the store has a body text, but it always return false. So, I can't get MMS bodytext.


By the way, I am using S60 3rd SDK.

void CMessageSend_S60::SetAttachmentToMsgL( TDesC& aBodyText, TDesC& aAttachedFileName )
{
//Opening store
CMsvStore* theStore = iMmsMtm->Entry().EditStoreL();
CleanupStack::PushL( theStore );

RFile theAttachment;
//open theAttachment file
TInt err = theAttachment.Open
(
CCoeEnv::Static()->FsSession(),
aAttachedFileName,
EFileShareReadersOnly | EFileRead
);

CleanupClosePushL( theAttachment );

//Check that the theAttachment file exist.
if( err != KErrNone )
{
theAttachment.Close();
CleanupStack::PopAndDestroy(2); // theAttachment, theStore

User::Leave( err );
}
else
{
//mime header
CMsvMimeHeaders* theMimeHeaders = CMsvMimeHeaders::NewL();
CleanupStack::PushL( theMimeHeaders );
theMimeHeaders->SetSuggestedFilenameL( KFileName );

// Represents a single attachment and information about the attachment
CMsvAttachment* theAttaInfo =
CMsvAttachment::NewL( CMsvAttachment::EMsvFile );
CleanupStack::PushL( theAttaInfo );

//Mime Type
TBufC8<10> theMimeType(KMimeType);

TMsvAttachmentId theAttachId = KMsvNullIndexEntryId;

// Attach body text to attachment
iMmsMtm->CreateTextAttachmentL
(
*theStore,
theAttachId,
aBodyText,
KBodyTextFileName
);


//Attachment file must be an public folder
iMmsMtm->CreateAttachment2L
(
*theStore,
theAttachment,
theMimeType,
*theMimeHeaders,
theAttaInfo,
theAttachId
);

// Ownership of attachmentinfo is transferred to attachment manager
// It must not be deleted by caller.
CleanupStack::Pop( theAttaInfo );
CleanupStack::PopAndDestroy( theMimeHeaders ); // theMimeHeaders

theStore->CommitL();
theAttachment.Close();

CleanupStack::PopAndDestroy(); // theAttachment
CleanupStack::PopAndDestroy(); // store
}
}

void CMessageSend_S60::HandleSessionEventL
(
TMsvSessionEvent aEvent,
TAny* aArg1,
TAny* aArg2,
TAny* aArg3
)
{
switch (aEvent)
{
// This event tells us that the session has been opened
case EMsvServerReady:
CompleteConstructL(); // Construct the mtm registry & MMS mtm
break;

case EMsvEntriesCreated:
{
ProcessNewMsg( aArg1, aArg2 );
}
break;

default:
break;
}
}

void CMessageSend_S60::ProcessNewMsg
(
TAny* aArg1,
TAny* aArg2
)
{
// entry id from the session event
TMsvId *parent = static_cast<TMsvId*>( aArg2 );
if ( KMsvGlobalInBoxIndexEntryId == *parent )
{
// Go through new messages..
// We take the created entries into a selection
CMsvEntrySelection* entries =
static_cast<CMsvEntrySelection*>(aArg1);

// entry pointer for making changes in the actual message contexts
CMsvEntry* entry = NULL;
TMsvId theNewMsgId;

//Process each created entry, one at a time.
for (TInt i = 0; i < entries->Count(); i++)
{


// Setting all messages in the selection as invisible
// this reserves memory for a new CMsvEntry
theNewMsgId = entries->At(i);

entry = iSession->GetEntryL( theNewMsgId );
entry->SetEntryL(theNewMsgId);

// Open the store
CMsvStore* theStore = entry->ReadStoreL();
CleanupStack::PushL( theStore );

// Get body text
if( theStore->HasBodyTextL() )
{
CRichText* theRichText = CRichText::NewL
(
CEikonEnv::Static()->SystemParaFormatLayerL(),
CEikonEnv::Static()->SystemCharFormatLayerL()
);

CleanupStack::PushL( theRichText );
theStore->RestoreBodyTextL( *theRichText );


CAknInformationNote* informationNote = new ( ELeave ) CAknInformationNote;
informationNote->ExecuteLD( theRichText->Read(0) );

CleanupStack::PopAndDestroy( theRichText);
}

CleanupStack::PopAndDestroy( theStore );

delete entry;
}
}
}

After study, I found I have to watch for EMsvEntriesCreated and EMsvEntriesChanged events in the inbox. When EMsvEntriesCreated event aarives, it has not been stored yet, so I can't read data from the entry; when EMsvEntriesChanged arrived, I have to tell it's a new message or change to an existing message.

So, I did some modification. But I still got false value for CMsvStore::HasBodyTextL(). I really don't know why I can't read MMS body text.

void CMessageSend_S60::HandleSessionEventL
(
TMsvSessionEvent aEvent,
TAny* aArg1,
TAny* aArg2,
TAny* aArg3
)
{
switch (aEvent)
{
// This event tells us that the session has been opened
case EMsvServerReady:
CompleteConstructL(); // Construct the mtm registry & MMS mtm
break;

case EMsvEntriesCreated: // Message created
{
if ( KMsvGlobalInBoxIndexEntryId == *(static_cast<TMsvId*>( aArg2 )) )
{
CMsvEntrySelection* entries = static_cast<CMsvEntrySelection*>(aArg1);
iNewMsgId = entries->At(0);
}
}
break;

case EMsvEntriesChanged:
{
if ( KMsvGlobalInBoxIndexEntryId == *(static_cast<TMsvId*>( aArg2 )) )
{
CMsvEntrySelection* entries = static_cast<CMsvEntrySelection*>(aArg1);
if( iNewMsgId == entries->At(0) )
{
// It's the same message we received the EMsvEntriesCreated event for
ProcessNewMsg();
}
}
}
break;

default:
break;
}
}

void CMessageSend_S60::ProcessNewMsg()
{
// entry pointer for making changes in the actual message contexts
CMsvEntry* entry = iSession->GetEntryL( iNewMsgId );
entry->SetEntryL(iNewMsgId);

// Open the store
CMsvStore* theStore = entry->ReadStoreL();
CleanupStack::PushL( theStore );

// Get body text
if( theStore->HasBodyTextL() )
{
CRichText* theRichText = CRichText::NewL
(
CEikonEnv::Static()->SystemParaFormatLayerL(),
CEikonEnv::Static()->SystemCharFormatLayerL()
);

CleanupStack::PushL( theRichText );
theStore->RestoreBodyTextL( *theRichText );


CAknInformationNote* informationNote = new ( ELeave ) CAknInformationNote;
informationNote->ExecuteLD( theRichText->Read(0) );

CleanupStack::PopAndDestroy( theRichText);
}

CleanupStack::PopAndDestroy( theStore );

delete entry;
}

Well the 'MMS MTM does not use its Body() member' also applies for incoming MMSs. Unfortunately I do not know what you should exactly do, but I would start with CMmsClientMtm::GetAttachmentsL.

[sophiachang]

Well I want to read the text file of incoming MMS and there is no CMmsClientMtm::GetAttachmentsL(I am using S60 3rd Edition SDK). Maybe I should start with CMsvStore::AttachmentManagerL() to get MMsvAttachmentManager::GetAttachmentFileL(). Thansk !

Hi,

Can somebody quickly share some smaple code to read MMS messages from Inbox. Thanks in advance!

Rush!

[zhenLeow]

// Get message body from entry storage (CMsvStore). CMsvStore stores whole
// message, not summary information ( see GetMessageIndexBodyTextL() ).
TBool CMMSMtmsEngine::GetMessageL( TMsvId aMessageId, TDes& aMessage)
{
iMmsMtm->SwitchCurrentEntryL( aMessageId );

if ( iMmsMtm->Entry().HasStoreL() )
{
// SMS message is stored inside Messaging store.
CMsvStore* store = iMmsMtm->Entry().ReadStoreL();
CleanupStack::PushL(store);

MMsvAttachmentManager& attachManager = store->AttachmentManagerL();

RFile file= attachManager.GetAttachmentFileL(0);

HBufC8* buf = HBufC8::NewL(100) ;
TPtr8 pBuf = buf->Des() ;
file.Read(pBuf); //pBuf now contains the text
file.Close();

CleanupStack::PopAndDestroy(store);
}
else
{
return EFalse;
}

return ETrue;
}

file.Close();

CleanupStack::PopAndDestroy(store);
}
else
{
return EFalse;
}

return ETrue;
}

this method is working for english body, but if the body is chinese words, there will be a problem. does anybody have a good idea to handle the chinese words MMS body?

Thanks.
John
