สร้างแบบฟอร์ม PDF ผ่าน C++

    // Open document
    auto document = MakeObject<Document>(_dataDir + u"TextField.pdf");

    // Create a field
    auto textBoxField = MakeObject<TextBoxField>(document->get_Pages()->idx_get(1), MakeObject<Aspose::Pdf::Rectangle>(100, 200, 300, 300));
    textBoxField->set_PartialName (u"textbox1");
    textBoxField->set_Value (u"Text Box");

    // TextBoxField.Border = new Border(
    auto border = MakeObject<Aspose::Pdf::Annotations::Border>(textBoxField);
    border->set_Width(5);
    border->set_Dash (MakeObject<Aspose::Pdf::Annotations::Dash>(1, 1));
    textBoxField->set_Border(border);

    textBoxField->set_Color(Aspose::Pdf::Color::get_Green());

    // Add field to the document
    document->get_Form()->Add(textBoxField, 1);

    // Save modified PDF
