Owner-draw with CTabCtrl using MFC

Question

Using VS 2015. I have a dialog-based app (NOT a PropertySheet), and have a CTabCtrl-derived object in which I want to disable specific tabs. From what I've googled, owner-draw is the way to go. Fine, can understand that.

What I would like to do is START with an owner-drawn version that acts exactly like the non-owner-drawn version, and then start tweaking it variously to experiment. For example, I'd like to use things like

void CTabControl::DrawItem( LPDRAWITEMSTRUCT lpDrawItemStruct )
{
    CTabCtrl::DrawItem( lpDrawItemStruct );  // do exactly what unmodified does
}

so that I am basically calling everything the unmodified CTabCtrl would do to accomplish the drawing. Even the simplest starting point would be helpful. What routines do I need to override or intercept to do this?

I'm setting TCS_OWNERDRAWFIXED in PreSubclassWindow() and doing what I showed above, and one or two other things, but the result definitely doesn't look the same. For one thing, no text in the tabs.

I'd really love it if I could get some pointers on where to start. BTW, I'm creating the control programatically (no dialog resources) like this (CTabControl inherits from CTabCtrl):

MyDlg::OnInitDialog()
{
    ...
    m_tabctrl = new CTabControl();
    m_tabctrl->Create( TCS_TABS | TCS_BOTTOM | TCS_HOTTRACK | TCS_FIXEDWIDTH | WS_CHILD | WS_VISIBLE, dummyRect, this, ID_TABCTRL );
    ...
}
