Visual C++ :: How To Create MDI Child With Borders

How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.

I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.

Code:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {
if( !CFrameWndEx::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = 250; // just playing around with size
cs.cy = 250;
return TRUE;
}

How can I do that?
