Static control is needed to use CHtmlEditCtrl class.

BOOL CSomeDlg::OnInitDialog()
{
    ...

    // TODO: Add extra initialization here
    CStatic wndStatic;
    wndStatic.SubclassDlgItem(IDC_HTMLSTATIC, this);

    CRect rect;
    wndStatic.GetWindowRect(rect);
    ScreenToClient(rect);
    if (m_ctlEditHtml.Create(NULL, WS_CHILD | WS_VISIBLE, rect, this, IDC_HTMLSTATIC) != TRUE)
        return FALSE;

    return TRUE;
}

By the way, there is a bug with hiding the control: BUG: WebBrowser Control Destroyed When Hidden.

How to reproduce:

Consider the following code:

m_ctlEditHtml.ShowWindow(SW_HIDE);
m_ctlEditHtml.ShowWindow(SW_SHOW);

The application crashes.

Workaround:

::ShowWindow(m_ctlEditHtml.GetSafeHwnd(), SW_HIDE);             
::ShowWindow(m_ctlEditHtml.GetSafeHwnd(), SW_SHOW);
