aradha,
I use a tab control form quite sucessfully in some of my applications. I design each subform to have no border with no record controls, scroll bars, close buttons, navigations buttons, dividing lines, etc, etc. It becomes a form with no controls. I then size it to fit in the tab control page, then attach it as a subform. All controls for records, close, etc, etc is done via command buttons on the face of the form. It takes a bit of experimentation as far as size but it works like a treat.
I hope this helps.
