How to make resizable PropertySheet?

I'm using MFC, and trying to make a subclass of CPropertySheet that is resizable. I've tried to override CWnd::PreCreateWindow(), but it isn't called. I can catch WM_NCCREATE using the message map and OR in WS_THICKFRAME to the window style, but that seems to be ignored. Does anyone know how to do this?

Although I'm not using NSViews directly, their code contained the secret incantation I was looking for, which I append here for posterity. Thanks NanoSoft!!!

int CNSFlexPropertySheet::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CPropertySheet::OnCreate(lpCreateStruct) == -1)
return -1;

LONG lSTYLE = GetWindowLong(m_hWnd,GWL_STYLE);
LONG lEXSTYLE = GetWindowLong(m_hWnd,GWL_EXSTYLE);

if ((lSTYLE & DS_MODALFRAME) == DS_MODALFRAME)
{
lSTYLE &= ~(LONG)DS_MODALFRAME;
lSTYLE |= WS_THICKFRAME;
SetWindowLong(m_hWnd,GWL_STYLE,lSTYLE);
}

if ((lEXSTYLE & WS_EX_DLGMODALFRAME) == WS_EX_DLGMODALFRAME)
{
lEXSTYLE &= ~(DWORD)WS_EX_DLGMODALFRAME;
SetWindowLong(m_hWnd,GWL_EXSTYLE,lEXSTYLE);
}
else
{
lEXSTYLE |= (DWORD)WS_EX_CLIENTEDGE;
SetWindowLong(m_hWnd,GWL_EXSTYLE,lEXSTYLE);
}

return 0;
}
