I don't have a specific example in front of me, but to steer you in the right direction:

1) You need to declare a form to be a MDI parent form
2) Declare other forms to be children of the MDI parent
3) Since it's 2005, you'll find an option on the menu strip control to define which menu pad will be the MDIWindowListItem.

Hope this helps.

>I have put up a traditional menu in my form with ofcourse Window menu pad item in it. My problem is, how could I make the system automatically list all active windows under the Window Menu pad just like other windows software system i.e. word, excel? I use C#.Net 2005.
