C++ API to Convert EML to OTT
Get Started with C++ File Format APIs
Install from command line as
nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load the EML file to be converted System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.eml"); // save EML as a HTML msg->Save(u"HtmlOutput.html", SaveOptions::get_DefaultHtml()); // load HTML with an instance of Document System::SharedPtr<Document> doc = System::MakeObject<Document>(u"HtmlOutput.html"); // call save method while passing Ott as save format doc->Save(u"convertedFile.Ott");
Parse EML File via C++
Not only you can convert your EML to OTT, but you can read, manipulate, and parse EML document. You can get subject, address, body, recipients information of the email by using MapiMessage class of Aspose.Email for C++ API. For example, you can check for a specific sender email for the conversion by using get_SenderEmailAddress() property.
// create an instance of MapiMessage from file System::SharedPtr<MapiMessage> msg = MapiMessage::FromFile(dataDir + L"message.eml"); // get subject System::Console::WriteLine(System::String(L"Subject:") + msg->get_Subject()); // get from address System::Console::WriteLine(System::String(L"From:") + msg->get_SenderEmailAddress()); // get body System::Console::WriteLine(System::String(L"Body") + msg->get_Body()); // get recipients information System::Console::WriteLine(System::String(L"Recipient: ") + msg->get_Recipients());
C++ API to Restrict OTT File Format Editing
You can also add document protection features in your app while exporting the document from EML to OTT. Adding protection to your document is a simple process, as all you need to do is apply the protection method to your document. You can set protection type to ReadOnly to restrict the user to edit the document.
// create a new document and protect it with a password. auto doc = System::MakeObject<Document>(); // apply Document Protection. doc->Protect(ProtectionType::ReadOnly, u"password"); // save the document. doc->Save(u"DocumentProtection.PasswordProtection.Ott");
