Hi.
You should see the common task in windows XP, that appears in left side of all windows(like My Computer , My Documents , ...), and when in a window (My Computer, for example) at "Tools menu -> Folder options ... -> General Tab -> Show common tasks in folders" is selected, it appears.
OK
I need a control like this to use, that has several portions and each portion expand and enclose like common tasks.
Anything can help me

Common Task Control
Diya.S
Such controls are often called ExplorerBars. Search for that and you'll find many options http://www.google.com/search q=explorerbar
