  2. Convert MSG to HTML by using Save member function
  3. Load HTML by using Document class
  4. Save the document to DOCM format using Save method and set Docm 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 .

System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.msg");
// save MSG 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 Docm as save format
doc->Save(u"convertedFile.Docm");

Parse MSG File via C++

Not only you can convert your MSG to DOCM, but you can read, manipulate, and parse MSG 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.msg");
// 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 DOCM File Format Editing

You can also add document protection features in your app while exporting the document from MSG to DOCM. 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.Docm");
