  {
    static void Main(string[] args)
    {
      PDFDocument doc = new PDFDocument();
      PDFPage page = new PDFPage(PDFPaperFormat.A4);

      PDFPushButton button = new PDFPushButton(10, 40, 100, 30, "btn1");
      button.Caption = "Button";
      page.Annotations.Add(button);

      PDFCheckBox checkBox = new PDFCheckBox(10, 100, 20, 20, "checkBox");
      checkBox.Checked = true;
      page.Annotations.Add(checkBox);

      PDFComboBox comboBox = new PDFComboBox(10, 200, 100, 20, "comboBox");
      comboBox.BackgroundColor = new PDFColorRGB(0, 255, 0);
      comboBox.Font.Size = 8;
      comboBox.Editable = true;
      comboBox.Text = "Editable combo box";
      comboBox.Items.Add("First item");
      comboBox.Items.Add("Second item");
      page.Annotations.Add(comboBox);

      PDFEditBox edit = new PDFEditBox(20, 300, 100, 50, "edit");
      edit.Multiline = true;
      edit.Font.Size = 8;
      edit.Text = "The quick brown fox jumps over, the lazy dog.";
      page.Annotations.Add(edit);

      doc.Pages.Add(page);

      doc.Save("PDFForms.pdf", true);
    }
  }
}
