C++ API to Export EML to EPUB

Transform EML to EPUB within C++ application without requiring Microsoft Word or Outlook

 

Are you are a C++ developer looking to add email conversion features inside your applications? Using Aspose.Email for C++ you can convert EML file format to HTML. After that, by using Aspose.Words for C++ API, you can export HTML to EPUB. Both APIs come under Aspose.Total for C++ package.

C++ API to Convert EML to EPUB

  1. Open EML file using MailMessage class reference
  2. Convert EML to HTML by using Save member function
  3. Load HTML by using Document class
  4. Save the document to EPUB format using Save method and set Epub as SaveFormat

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 Install-Package Aspose.Total.Cpp.

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 Epub as save format
doc->Save(u"convertedFile.Epub");

Parse EML File via C++

Not only you can convert your EML to EPUB, 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 EPUB File Format Editing

You can also add document protection features in your app while exporting the document from EML to EPUB. 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.Epub");
