How can I size client rect precisely ?

To size a view at wanted size,
In my view class's OnInitialUpdate,

 rect.left   = 100;
 rect.top    = 100;
 rect.right  = 200;
 rect.bottom = 200;

 AdjustWindowRect( &rect, AfxGetMainWnd()->GetStyle(), TRUE);
 AfxGetMainWnd()->MoveWindow( rect, TRUE);

And then,
In OnDraw,
 I call GetClientRect,

The result I wanted was ( 0, 0, 100, 100),
BUT the result was -> ( 0, 0,  96,  96) !
I guess difference 4 is border's thickness,
 but I started this app by turning off "Thick Frame".

What is wrong ?

To size a view at wanted size,
I try CalcWindowRect and AdjustWindowRect.
But Both were wrong.

And in case of adopting ToolBar and/or StatusBar,
 problems get worse.

How can I do it ?

Thanks in advance.

    Put the  CalcWindowRect call in  your frame window's  OnCreate, then
call MoveWindow, and  things should be fine. What's  happening is, since
the  View does  not  have  a "frame",  CalcWindowRect  returns the  rect
unchanged. So, effectively, you're using the same initial values to size
the Frame, not taking the Frame's "frame" into account.

    For correct View sizing with ToolBars/StatusBars, use RepositionBars
with  the reposQuery  option (again)  in your  Frame window's  OnCreate,
passing  the View's  desired size.  Then call  MoveWindow with  the Rect
returned,      and       RepositionBars      again.       Check      out
ftp://ftp.microsoft.com/softlib/mslfiles/DLGCBR32.EXE.    This   program
explains the procedure for a Dialog, but the same principle applies.
