1.MFC tab标签:

int CurSel = m_tab.GetCurSel();

2.MFC CString to int;

    CString stringTemp = L"45";
    int iShopState = _ttoi(stringTemp);

3.MFC 禁止拷贝:

BOOL Account::PreTranslateMessage(MSG* pMsg)
{
    // TODO: 在此添加专用代码和/或调用基类
    if (GetDlgItem(INPUT)->m_hWnd == pMsg->hwnd ||
        GetDlgItem(INPUT2)->m_hWnd == pMsg->hwnd )
    {
        if (pMsg->message == WM_RBUTTONUP || pMsg->message == WM_KEYDOWN && pMsg->wParam == 'V' && (GetAsyncKeyState(VK_CONTROL) & 0x8000))
            return TRUE;
    }
    return CDialogEx::PreTranslateMessage(pMsg);
}

4.mysql 删除重复字段数据;

delete from user_account where user_idx not in  ( select * from  (select max(user_idx) ",
    " as max_id from user_account group by card_idx,phone) b where user_account.user_idx=b.max_id
