Remarks
The IHTMLElement2::doScroll method is available on all objects, regardless of whether they support scrollbars.
Cascading Style Sheets (CSS) allow you to scroll on all objects through the IHTMLStyle::overflow property.
When the content of an element changes and causes scroll bars to display, the IHTMLElement2::doScroll method might not work correctly immediately following the content update. When this happens, you can use the IHTMLWindow2::setTimeout method to enable the browser to recognize the dynamic changes that affect scrolling.
