Edit PPTX properties using C++

Build your own C++ apps to modify Built-in and Custom properties in presentation files using server-side APIs.

Modify PPTX Properties via C++

Using Aspose.Slides for C++, developers can access and modify the values of built-in properties as well as custom properties. Developers can use DocumentProperties property exposed by Presentation object to access the document properties of the presentation file.

Modify PPTX Built-in Properties - C++
// Instantiate the Presentation class that represents the Presentation
System::SharedPtr<Presentation> presentation = System::MakeObject<Presentation>(u"presentation.pptx");

// Create a reference to IDocumentProperties object associated with Presentation
System::SharedPtr<IDocumentProperties> documentProperties = presentation->get_DocumentProperties();

// Set the builtin properties
documentProperties->set_Author(u"New Author");
documentProperties->set_Title(u"New Title");

// Save your presentation to a file
presentation->Save(u"DocumentProperties_out.pptx", SaveFormat::Pptx);

Add Custom Properties to PPTX - C++
// Instantiate the Presentation class
auto presentation = System::MakeObject<Presentation>();

// Getting Document Properties
auto documentProperties = presentation->get_DocumentProperties();

// Adding Custom properties
documentProperties->idx_set(u"New Custom", ObjectExt::Box<int32_t>(12));
documentProperties->idx_set(u"My Name", ObjectExt::Box<String>(u"Aspose Metadata Editor"));
documentProperties->idx_set(u"Custom", ObjectExt::Box<int32_t>(124));

// Getting property name at particular index
String getPropertyName = documentProperties->GetCustomPropertyName(2);

// Removing selected property
documentProperties->RemoveCustomProperty(getPropertyName);

// Saving presentation
presentation->Save(u"CustomDocumentProperties_out.pptx", SaveFormat::Pptx);
