can't get correct rect of the toolbar

I want to position a button at the extreme right edge of the toolbar,
In main frame on create i create the toolbar and the buttons,
 in MainFrame::onCreate()
m_toolbar.GetClientRect returns me width and height of 0. Then i tried the Mainframe.getwindowrect which gives me less than the correct values(incidentally the keep changing each time),Could any body figure out the flaw in my pprocah, or thera a problem with MFC?
How can i get the actual(correct) size of the toolbar

Any CControlBar-derived object (like CToolbar) always creates itself with a zero size.  Then, it negotiates with the view, the frame and the docking sites to find a size.

In fact, during the lifetime of the bar, it may change shape and orientation several times--try undocking a toolbar and dragging it around!

The bar will only have a valid rect after CalcLayout() has been called at least once. That happens in response to several situations: the frame being initially created, the frame changing size, the user docking or undocking any bar from or to the frame, or the user moving this particular bar.

Adding an extra control to a toolbar from the outside is going to be dicey at best. You should derive your own class from the toolbar. Then, account for your new control's size when CalcLayout() is called. When the bar changes size, make sure you move your button to an appropriate spot depending on the orientation and layout of the control.
