// access first slide
SharedPtr<ISlide> sld = pres->get_Slides()->idx_get(0);
// add an AutoShape of Rectangle type
SharedPtr<IAutoShape> ashp = sld->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 10, 10, 700, 500);
// reset default fill color
ashp->get_FillFormat()->set_FillType(FillType::NoFill);
// add TextFrame to the Rectangle
ashp->AddTextFrame(u" ");
// access the text frame
SharedPtr<ITextFrame> txtFrame = ashp->get_TextFrame();
// get Paragraphs collection
SharedPtr<Aspose::Slides::IParagraphCollection>ParaCollection = txtFrame->get_Paragraphs();
// clear all paragraphs in added text frame
ParaCollection->Clear();
// load the HTML file using stream reader
SharedPtr<System::IO::StreamReader> tr = MakeObject<System::IO::StreamReader>(HtmlOutput.HTML);
// add text from HTML stream reader in text frame
ParaCollection->AddFromHtml(tr->ReadToEnd());
// save presentation as Potx
pres->Save(output.potx, Aspose::Slides::Export::SaveFormat::Potx);

Load Password Protected DOCM Document via C++
Apart from document conversion, Aspose.Words for C++ API allows tons of document manipulation features for C++ developers. In case your Microsoft Word DOCM file format is password protected, you can still open it using the API. In order to load the encrypted document, you can use a special constructor overload, which accepts a LoadOptions object. This object contains the Password property, which specifies the password string.
// when loading password protected document, the password is passed to the document's constructor using a LoadOptions object.
auto options = MakeObject<LoadOptions>(u"docPassword");
// load the document from the local file system by filename:
SharedPtr<Document> doc = MakeObject<Document>(u"Encrypted.docm", options);
Add Comments in POTX Document via C++
While saving DOCM as POTX, you can also use Aspose.Slides for C++ to add further features in your POTX document. For instance, you can add comments in your presentation. The presentation slide comment are associated with a particular author. The Presentation class holds the collection of authors in ICommentAuthorCollection that are responsible for adding slide comments. For each author, there is a collection of comments in ICommentCollection.
// instantiate Presentation class
SharedPtr<Presentation>pres = MakeObject<Presentation>();
// access first slide
SharedPtr<ILayoutSlide>layout = pres->get_LayoutSlides()->idx_get(0);
// add empty slide
pres->get_Slides()->AddEmptySlide(layout);
// adding Author
SharedPtr<ICommentAuthor> author = pres->get_CommentAuthors()->AddAuthor(u"John Doe", u"MF");
// set position of comments
System::Drawing::PointF point = System::Drawing::PointF(0.2f, 0.2f);
// add slide comment for an author on slide 1
author->get_Comments()->AddComment(u"Hello John, this is a slide comment", pres->get_Slides()->idx_get(1), point, DateTime::get_Now());
// access ISlide 1
SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);
// save presentation as Potx
pres->Save(output.potx, Aspose::Slides::Export::SaveFormat::Potx);
