Adding attachments to messages

The messaging framework allows you to add attachments to messages.

Steps

1. Create an active object implementation. All the MMsvAttachmentManager functions that modify attachments for an entry are asynchronous, so a request must be called with an active object implementation.

   //* Active object request function to add an attachment.
   Arguments:
   aEntry -  entry to make attachment for
   aAttachPath -  path of file to attach
   aSize - size of attachment in bytes 
   */
   
   void CFoo::AttachFileL(CMsvEntry& aEntry, const TFileName& aAttachPath, TInt aSize)
       { 
   ...
       // Wait for request to complete
       User::WaitForRequest(status);
           
       CleanupStack::PopAndDestroy(store);    
       }
   
   

2. Get the details of the message to which you want to add an attachment using CMsvEntry::EditStoreL().

   This function returns CMsvStore in writable mode.

       // Get store   
       CMsvStore* store = aEntry.EditStoreL();
       CleanupStack::PushL(store);
   

3. Get an MMsvAttachmentManager attachment manager for the message entry, using CMsvStore::AttachmentManagerL().

       // Get attachment manager from the entry's store     
       MMsvAttachmentManager& attManager = store->AttachmentManagerL();    
   

4. Create a new attachment attributes object using the CMsvAttachment::NewL() function.

       // Create a new attachment attributes object    
       CMsvAttachment* attachment = CMsvAttachment::NewL(CMsvAttachment::EMsvFile);    
       CleanupStack::PushL(attachment);    
   

5. Set the attachments name and size attributes using the functions of the CMsvAttachment class.

       // Set the attachment name and size attributes    
       TParse fparse;    
       User::LeaveIfError(fparse.Set(aAttachPath,NULL,NULL));    
       attachment->SetAttachmentNameL(fparse.NameAndExt());    
       attachment->SetSize(aSize);
   

6. Add the attachment using any of the following functions:

   1. For copied attachments, use the MMsvAttachmentManager::AddAttachmentL() function.

   2. For linked attachments, use the MMsvAttachmentManager::AddLinkedAttachmentL() function.
   Note: For OBEX MTM, to add headers to an attachment, use the CObexHeaderList::ExportToAttachmentL() function. Headers can be retrieved using the CObexHeaderList::ImportFromAttachmentL() function.

       TRequestStatus status;
            
       // Ownership of attachment will transfer to attachManager    
       CleanupStack::Pop(attachment);
       // Add the attachment    
       attManager.AddAttachmentL(aAttachPath, attachment, status);    
   

7. Commit the store.
