[C#] DayDiff 取得天數差異

C# 裡面沒有 DateDiff 這種很方便取得時間差異的函式，雖然可以引用 Microsoft.VisualBasic來 使用裡面的 DateAndTime.DateDiff Method，不過不是每個人都想這樣做，所以只好自己來寫一個合用的，保哥有一篇文章寫了用 TimeSpan 判斷日期差異的方式，但是這也不合我用，所以就自己亂寫了一個。

protected int DayDiff(DateTime dfrom,DateTime dto)
        {
            int day;
            day=DateTime.IsLeapYear(dfrom.Year)?366:365;

            if (dto.Year == dfrom.Year)
                return dto.DayOfYear - dfrom.DayOfYear;
            else if (dto.Year > dfrom.Year)
                return dto.DayOfYear - dfrom.DayOfYear + day;
            else
                return dto.DayOfYear - dfrom.DayOfYear - day;
        }

會這樣寫主要是要讓某些狀況下的結果是正確的，例如今天23:00跟明天01:00，應顯示差一天，這時 TimeSpan 求出來的結果就會是零天，還有順便加上閏年的判斷。因為需求關係，我這寫法沒有去判斷跨多年的情況，如果有需要的話再自行加上吧。

I AM NIKON

最近在電視上，看到了Nikon的這個形象廣告，相當有意境，於是上網找了一下，原來有相當多版本，甚至各國都有各自拍攝不同主題的版本，不過台灣撥出的廣告在Youtube上居然只有360P版本，NikonTaiwan實在是該打屁股，怎麼不丟HD畫質的呢 ? 所以我就放了上面那段比較完整的Brand Film，個人覺得相當精采。

選舉到了才愛國旗

原本想在十月十號貼這篇文章，不過人一懶就拖到現在了。

馬政府上台後，台灣各個場合已經很難看到國旗的出現了，甚至拿國旗會被警察打、被關，國旗會被警察搶去丟掉、折掉，反而是中共五星旗可以大辣辣地在街上出現，我還看過在車上插著大大的五星旗，從警察前面開過博愛特區，也不會有事。

近來選舉到了，馬政府為了選舉，為了選票，又開始騙大家他們是愛國，愛國旗的，真是可笑至極。

Port of FTPS (implicit SSL)

因為年紀大了記性不好，所以特別把FTPS(FTP over implicit TLS/SSL)所要開的Port列一下，避免下次忘記的時候又要找一次。

Port	用途
21	cmd port
50000~50020	50000~50020:傳輸資料PORT：此PORT若沒開,可以登入,但下list cmd命令時(如LS)則會無法看到目錄與資料
990	990:交換SSL KEY 加密用

公司網站上常常有這個錯誤，不過放了很久卻都沒有人去解，今天找了一下解法，大致上有兩種。

先說說原因，這問題的主要原因通常是在輸出資料時，使用者已經關閉連線(關掉瀏覽器)，但是程式卻不知道，於是跑到 Response.Flush(); 的時候，就會產生這個錯誤。

解法一是加上Response.Buffer = false;
解法二是在 Flush 前先用 Response.IsClientConnected 去判斷是否還有連線，有的話再繼續。

這錯誤有點難模擬，所以我沒有兩個都試然後去看結果，所以只用了第一個，解法二看起來還是會有很小的機會發生同樣的錯誤就是。

[C#] 取得WebRequest錯誤後的資訊

日前在用 WebRequest 與廠商串接功能，他們的錯誤訊息蠻特別的，是直接回 HTTP Error 400 Bad request ，然後把 error code 寫到 body 裡，在 C# 裡使用 WebRequest 一遇到 Status Code 400 就會跳錯誤了，所以沒辦法用原本的方式接資料，原本還在想要不要用 wget 先 debug ，後來找了一下才知道可以用 WebException 去讀出回傳的資料，這就方便了許多，方法如下。

            try
            {
                //your WebRequest , WebResponse
            }
            catch (WebException e)
            {
                Stream dataStream = e.Response.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream, encode);                
                Console.WriteLine(reader.ReadToEnd());
            }

這樣就可以拉到錯誤時的資訊了。

[JS] Close fancybox within iframe

雖然 fancybox 的 API 文件中有說到在iframe中可使用 parent.$.fancybox.close(); 去關掉 fancybox ，但是我實際上測試卻是不會動，後來在網路上找半天，各種做法都搞不定，最後只好用很笨的方法，直接把 fancybox 顯示出來的圖層關掉：

        parent.jQuery('#fancybox-overlay').css('display', 'none');
        parent.jQuery('#fancybox-wrap').css('display', 'none');

後來想了一想，用了比較好的做法，程式上比較美觀，雖然我看不出來在表現上有啥差別。

    //parent
    function CloseFancy()
    {
        $.fancybox.close();
    }
    //iframe
    function fancyclose() {
        parent.CloseFancy();
    }

如果有用 fancybox ，可以參考一下，不過 fancybox 跟 BlockUI 會有衝突，我還找不到方法解，要注意一下就是。

[JS] 讀取條約後才可繼續 / EULA Scroll to End

有朋友問我個問題，就是一些使用者合約要看完才能繼續的功能怎麼做，想想我也沒試過，於是就來搞一下。做好的樣子就長的像下面一樣，手邊沒啥EULA所以上網找了D3的test agreement來用。
