## Examples



Shows how to work with a document's collection of web extensions. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Web extension.docx"));

ASSERT_EQ(1, doc->get_WebExtensionTaskPanes()->get_Count());

// Print all properties of the document's web extension.
System::SharedPtr<Aspose::Words::WebExtensions::WebExtensionPropertyCollection> webExtensionPropertyCollection = doc->get_WebExtensionTaskPanes()->idx_get(0)->get_WebExtension()->get_Properties();
{
    System::SharedPtr<System::Collections::Generic::IEnumerator<System::SharedPtr<Aspose::Words::WebExtensions::WebExtensionProperty>>> enumerator = webExtensionPropertyCollection->GetEnumerator();
    while (enumerator->MoveNext())
    {
        System::SharedPtr<Aspose::Words::WebExtensions::WebExtensionProperty> webExtensionProperty = enumerator->get_Current();
        std::cout << System::String::Format(u"Binding name: {0}; Binding value: {1}", webExtensionProperty->get_Name(), webExtensionProperty->get_Value()) << std::endl;
    }
}

// Remove the web extension.
doc->get_WebExtensionTaskPanes()->Remove(0);

ASSERT_EQ(0, doc->get_WebExtensionTaskPanes()->get_Count());
```
