Thats tricky !! but quite possible.
Actually what you do is, put the SSTAB (microsoft tabbed dialog control) over the form. lets say u have 3 tabs
you go to first tab and put a frame over it in a way that it completely covers the tab control so hiding the tab also.
Now you put subsequent frames on subsequent tabs here You need to use tab property of SSTAB from property window to switch tabs (as frame1 has covered entire tab control, property window is only way to switch between tabs).

The solution proposed earlier is also very fine but y i'm recommending the tab dialogue coz it handles the visibility of the frames itself, so u can concentrate more on other parts of code.

give it a try.
