How do I add scrollbars to a dialog

I have a TopWindow derived dialog with (currently) empty layout and StaticText and ArrayCtrl controls inserted with new and Add().
The dialog is resizable.
I wish to allow controls hidden by the resizing to be scrolled into view.
I added to the dialog ctor:
AddFrame(m_Sb); // (ScrollBars m_Sb;)
m_Sb.HideX();
m_Sb.WhenScroll = [=] { Ctrl::Refresh(); };
but no joy (no scrollbar appears).
How do I do this?
Thanks.

Got a little further with this. V scrollbar appears ok but client ArrayCtrl and StaticText controls are not redrawn.
How do I get the visible area to redraw on scrolling?
MyDlg::MyDlg()
{
AddFrame(m_Sb); // (ScrollBars m_Sb;)
m_Sb.HideX();
m_Sb.WhenScroll = [=] { Ctrl::Refresh(); };
}
void MyDlg::Init()
{
.
.
.
Size S = {0, nWindowHeight};
m_Sb.SetTotal(S);
m_Sb.SetPageY(nWindowHeight); // No scrollbar initially
m_Sb.SetLine(0);
}
void MyDlg::Layout()
{
m_Sb.SetPageY(GetRect().GetSize());
}
