How can the contentEditable attribute, with a div tag, be added to the HTML message stream so an HTML message can be edited for a reply in a winform using the webcontrol object?

The complexity is that HTML messages may contain full HTML document with <!DOCTYPE>, <HTML>, <HEAD>, etc. Placing such HTML into a <DIV> would not allow you to display the document correctly.

There are two possible ways:

- remove everything except contents of <BODY></BODY> tag and place it inside a <DIV></DIV>;
- place <DIV></DIV> inside <BODY></BODY>.

In both the cases, MailBee.Html namespace would be useful to you. The following sample implements the second approach:

Code:

using MailBee;

using MailBee.Mime;

using MailBee.Html;

MailMessage msg = new MailMessage();

msg.LoadMessage(@"D:\test.eml");

Processor htmlProcessor = new MailBee.Html.Processor();

// Assign HTML body from the message to HtmlProcessor

htmlProcessor.Dom.OuterHtml = msg.GetHtmlAndSaveRelatedFiles();

if (htmlProcessor.Dom.GetInnerElementsByName("BODY").Count > 0)

{

    // Get reference to <BODY></BODY> element

    Element bodyElement = htmlProcessor.Dom.GetInnerElementsByName("BODY")[0];

    // Create new <DIV> element

    Element divElement = new Element("<div contentEditable=\"true\"></div>");

    // Copy all contents of <BODY> to the <DIV>

    foreach (Element elem in bodyElement.InnerElements)

    {

        divElement.InnerElements.Add(elem);

    }

    // Remove all <BODY> subelements

     bodyElement.InnerElements.RemoveAll( );

    // Add <DIV> to <BODY>

     bodyElement.InnerElements.Add(divEle ment);

    // Get the resulting HTML

    string str = htmlProcessor.Dom.OuterHtml;

    webBrowser1.DocumentText = str;

}

else

{

    MessageBox.Show("Message doesn't contain BODY tag");

}

Andrew
