Why to Convert
Converting a document from one format to another is a common requirement for many applications. For example, a DOCM file may need to be converted to a POTM file for use in a presentation. This can be done manually, but it is often more efficient to use an automated process.
How Aspose.Total Helps for DOCM to POTM Conversion
Aspose.Total for C++ is a powerful file automation API that allows users to automate the conversion of DOCM to POTM files. This is done by using two of its APIs: Aspose.Words for C++ and Aspose.Slides for C++.
The process begins by loading the DOCM file using Aspose.Words for C++. This API allows users to read and write a variety of document formats, including DOCM. Once the file is loaded, it can be converted to HTML using the API.
The HTML can then be loaded via the PowerPoint manipulation C++ API, Aspose.Slides for C++. This API allows users to create a new presentation from the HTML, and then save it as a POTM file.
Aspose.Total for C++ is a powerful and efficient way to automate the conversion of DOCM to POTM files. It is easy to use and can save users time and effort when dealing with large numbers of documents.

// load DOCM file with an instance of Document
Document document = new Document("template.docm");
System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.docm");
// save the document in HTML file format
doc->Save(u"HtmlOutput.HTML");
// load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>();
// 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 Potm
pres->Save(output.potm, Aspose::Slides::Export::SaveFormat::Potm);

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 POTM Document via C++
While saving DOCM as POTM, you can also use Aspose.Slides for C++ to add further features in your POTM 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 Potm
pres->Save(output.potm, Aspose::Slides::Export::SaveFormat::Potm);
