Html Edit:

  DHTMLEdit/MSHTML Editor

The Microsoft Dynamic HTML (DHTML) Editing Component allows Web authors and application developers to add HTML editing capabilities to their Web sites and applications. The editing component uses Microsoft's Component Object Model (COM) technology to make editing services such as basic HTML formatting, tables, undo and redo, find, and absolute positioning readily available.

The DHTMLEdit component was developed back in the days of Internet Explorer 4.0 to supplement the limited features available in the editor at that time. The DHTML edit control is a Microsoft ActiveX control that wraps the DHTML editing component and provides some additional functionality such as saving and loading documents.

With the introduction of IE 5.5, the DHTMLEdit component has been superseded by the MSHTML Editor.

the DHTML editor will no longer be updated, so hosts are encouraged to use the MSHTML editor directly unless they require a specific feature that’s not yet supported. The only remaining features provided by the DHTML editing component that aren’t supported in the MSHTML editor in Internet Explorer 5.5 are source preservation, z-index operations, and some table operations such as insertion and deletion of tables, rows, and columns. Source preservation is only required by Web authoring applications that provide an HTML Source View, and z-index operations are easily performed through the DOM. In Internet Explorer 5.5, hosts can write their own custom extensions to perform whatever table editing operations their application requires.

I this section you can find components using the DHTMLEdit Component and components showing how to activate MSHTML Editor in IE 5.5 and implement EditHost and EditDesigners.
