Question

Is there a flag to prevent the CDHTMLDialog from use the IE history (back, backspace, context menu)? Or is there a event to look for?
I don’t seem to track it in PreTranslateMessage().

Check out these MSDN references and the sample code:
TranslateAccelerator and
ShowContextMenu

STDMETHODIMP CDHtmlDialogSubclass::ShowContextMenu(DWORD dwID, POINT *ppt, IUnknown *pcmdtReserved, IDispatch *pdispReserved)
{
    return S_OK;
}

STDMETHODIMP CDHtmlDialogSubclass::TranslateAccelerator(LPMSG lpMsg, const GUID * pguidCmdGroup, DWORD nCmdID)
{
    if (lpMsg && lpMsg->message == WM_KEYDOWN && 
        (lpMsg->wParam == VK_F5 ||
        lpMsg->wParam == VK_CONTROL))
    {
        return S_OK;
    }
    return CDHtmlDialog::TranslateAccelerator(lpMsg, pguidCmdGroup, nCmdID);
}
