What type of add-ins are you referring to? DeskBands, Explorer Bars, ToolBars, Browser Helper Objects? Other? The "Creating DeskBands with an ATL Object Wizard" in the ATL section, has links to MSDN Online resources for creating deskbands and toolbars, there are old MSJ/MIND articles that explain how to do browser helper objects and explorer bars. The links I made reference to are in the comments section of the article, in one of the postings from me. Hope this helps, -Erik
