Generate a Word document dynamically with user submitted text formatted with Free Text Box

Generate a Word document dynamically with user submitted text formatted with Free Text Box
This code sample show how to generate a Word document dynamically with user submitted text formatted with a rich text editor control like Free Text Box. By cross posting the formatted text (captured through FreeTextBoxdemo.aspx) to a separate Word file generation page (GenerateWordDoc.aspx) the HTML content that makes up the Word document is cleaner. Note that although the code below doesn't do it, any input submitted to the server ( specially because ValidateRequest="false" ) should be sanitized to prevent any cross-site scripting (XSS) attacks.

FreeTextBoxdemo.aspx:

<%@ Page Language="C#"  ValidateRequest="false"%>

<%@ Register Assembly="FreeTextBox" Namespace="FreeTextBoxControls" TagPrefix="FTB" %>
