更新有关插入符号更改插入消息的消息的插入符号

Got a solution
update the Caret on messages that change caret painting

// Handling EN_SETFOCUS notification
// ON_CONTROL_REFLECT_EX(EN_SETFOCUS, OnEnSetFocus)
BOOL RichEditEx2::OnEnSetFocus()
{
    UpdateCaret();
    return FALSE;
}

// WindowProc overrides
LRESULT RichEditEx2::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
    switch( message)
    {
    case WM_CHAR:
    case WM_UNICHAR:
    case WM_KEYDOWN:
    case WM_KEYUP:
    case WM_LBUTTONDOWN:
    case WM_LBUTTONUP:
    case WM_INPUTLANGCHANGE:
    case WM_IME_COMPOSITION:
    case WM_HSCROLL:
    case WM_VSCROLL:
        {
            LRESULT lResult = CRichEditCtrl::WindowProc(message, wParam, lParam);
            // Update Caret display.
            UpdateCaret();
            return lResult;
        }
    default:
        break;
    }

    return CRichEditCtrl::WindowProc(message, wParam, lParam);
}
