Aspose.Email for CPP 23.1 Release Notes

Aspose.Email for C++ 23.1 is based on Aspose.Email for .NET 22.12.

Aspose.Email for C++ does not support asyncronic features of e-mail protocols

New Features

Provide method to get Get Total Items Count of PersonalStorage

We have added the GetTotalItemsCount() method to PersonalStorage.Store property. It returns the total number of message items contained in the PST.

Code example:

auto pst = PersonalStorage::FromFile(u"my.pst", false);
auto count = pst->get_Store()->GetTotalItemsCount();

Getting and adding a standard RSS Feeds folder in PersonalStorage.

A new RssFeeds value has been added to StandardIpmFolder enum.

The following is a code example to get an RSS Feeds folder.

auto pst = PersonalStorage::FromFile(u"my.pst", false);
auto rssFolder = pst->GetPredefinedFolder(StandardIpmFolder::RssFeeds);

And code example to add an RSS Feeds folder.

auto pst = PersonalStorage::Create("my.pst", FileFormatVersion.Unicode);
auto rssFolder = pst->CreatePredefinedFolder(u"RSS Feeds", StandardIpmFolder::RssFeeds);

Setting a product ID when save MapiCalendar to ICS

We have added ProductIdentifier property to MapiCalendarIcsSaveOptions class. This property specifies the identifier for the product that created the iCalendar object.

Code sample:

auto icsSaveOptions = System::MakeObject<MapiCalendarIcsSaveOptions>()
icsSaveOptions->set_ProductIdentifier(u"Foo Ltd");

mapiCalendar->Save(u"my.ics", icsSaveOptions);

Extract messages from OLM and MBOX by identifiers

Sometimes it is required to extract selected messages by identifiers. For example, your application stores identifiers in a database and extracts a message on demand. This is the efficient way to avoid traversing through the entire storage each time to find a specific message to extract. This feature is now available for OLM and MBOX storages.

New API members in OLM implementation:

  • Added EntryId property to OlmMessageInfo class.
  • Added overloaded ExtractMapiMessage(String id) method to OlmStorage class.

Code example:

for (auto msgInfo : IterateOver(olmFolder->EnumerateMessages()))
    MapiMessage msg = storage->ExtractMapiMessage(msgInfo->get_EntryId());

New API members in MBOX implementation:

  • Added MboxMessageInfo class with the EntryId property.
  • Added EnumerateMessageInfo() method to MboxStorageReader class.
  • Added ExtractMessage(String id) method to MboxStorageReader class.

Code example:

auto reader = MboxStorageReader::CreateReader(u"my.mbox", System::CreateObject<MboxLoadOptions>());

for (auto msgInfo : IterateOver(reader->EnumerateMessageInfo()))
    MapiMessage msg = storage->ExtractMapiMessage(msgInfo->get_EntryId(), System::CreateObject<EmlLoadOptions>());

Note: The message ID is unique within the storage file. IDs are created by Aspose.Email and cannot be used in other third-party OLM/MBOX processing libs or apps.

Add IsInline property in Attachment

Changes in public API:

  • MapiAttachment::get_IsInline() - Gets a value indicating whether the attachment is inline or regular.

Code samples:

auto message = MapiMessage::Load(fileName);

for (auto attach : IterateOver(message->get_Attachments()))
    Console::WriteLine(attach->get_DisplayName0(),  attach->get_IsInline());

The full code of the examples can be found at Aspose Email for C++ GitHub examples repository.
