    }
    
    // Here you can call any Toolkit functions that will manipulate
    // the input file such as text and image stamping, form filling, etc.
    
    // Copy the template (with any changes) to the new file
    // Start page and end page, 0 = all pages
    intCopyForm = oTK.CopyForm(0, 0);
    if (intCopyForm != 1)
    {
      ErrorHandler("CopyForm", intCopyForm);
    }
    
    // Close the new file to complete PDF creation

    // Process Complete
    System.Diagnostics.Debug.WriteLine("Done!");

  // Error Handling
  public static void ErrorHandler(string strMethod, object rtnCode)
  {
