I am having a difficult time figuring out how to do this.  I added a 
handler to my property sheet for WM_WINDOWPOSCHANGED, and handlers for
WM_SIZE to each of my pages.  After resizing, the property page is a
mess ( I know that isn't very specific but don't know how else to 
put it ).  Another problem is the OnSize() handler for 
the page is called before the page is fully created.  Can anyone give
me an example of this?  I would think that this is hardly the most
difficult thing to do!  Here is my code:

// Property sheet
void CTranscript::OnWindowPosChanged(WINDOWPOS FAR* lpwndpos) 
{
	CPropertySheet::OnWindowPosChanged(lpwndpos);
	
	for( int i = 0; i < GetPageCount(); i++ ) {
		SetActivePage ( i );
		if( GetPage( i )->m_hWnd ) {
		    GetActivePage( )->SetWindowPos( &wndTop,  
				                    lpwndpos->x, 
						    lpwndpos->y,
lpwndpos->cx,
                                                    lpwndpos->cy,
                                                    lpwndpos->flags );
		}
        }

	SetActivePage ( 0 );
}

// resize the one and only control on the page-a multiline
// edit control.  It needs to take up most of the room
// on the page.
void CLinkPage::OnSize(UINT nType, int cx, int cy) 
{
	CPropertyPage::OnSize(nType, cx, cy);
	
	CTranscript* psht = ( CTranscript* ) GetParent ();
	if ( !psht->m_sheetCreated )
		return;

	CEdit* pEd = ( CEdit* ) GetDlgItem ( IDC_LINK_TRANS_EDIT );

	pEd->SetWindowPos( &wndTop, 
				20, 
				20,
				cx - 20,
				cy - 20,
				SWP_NOZORDER );
}

Thanks for any help.

    Check out MSKB article Q143291: "How to Resize CPropertyPages at Run
Time"... Basically, you  need to resize the Property  Sheet, Tab Control
and the Property  Pages in your OnInitDialog() override,  and resize the
pages when  you receive TCN_SELCHANGE  notifications and when  the Apply
button is pressed...
