網站同時使用 C# 與 VB.net
由於早期網站都是VB.net寫的,若是直接換成 C#,就會耗費很多時間在轉換程式上
因此 ASP.NET 特別可以在同一網站同時寫 vb 跟 C#,方式是在 web.config compilation 加上設定
    <compilation debug="true" defaultLanguage="c#" targetFramework="4.0">
     <codeSubDirectories>
        <add directoryName="VB_Code"/>
        <add directoryName="CS_Code"/>
     </codeSubDirectories>
    </compilation>

也就是 VB.NET 的 code 就放到 ~\APP_Code\VB_Code 目錄
C# 的 code 就放到 ~\APP_Code\CS_Code 目錄
這樣做有兩點要注意
1.  Namespace 的命名,最好不要互相衝突, 要能夠區分出來
2.  VB_Code 與 CS_Code 放的位置有很大的影響, 因為牽涉到 compiler的先後順序,因為 VB_Code 在 CS_Code 在前面,所以 CS_Code可以叫用 VB_Code下的程式,但是 VB_Code 卻不能叫用 CS_Code 的程式,如果希望 VB_Code可以叫用 CS_Code的程式,就把設定換過來
    <compilation debug="true" defaultLanguage="c#" targetFramework="4.0">
     <codeSubDirectories>
        <add directoryName="CS_Code"/>
<add directoryName="VB_Code"/>
     </codeSubDirectories>
    </compilation>

缺點就是反過來 CS_Code不能使用 VB_Code的程式

基本上,若是舊的程式碼都在VB_Code 那就把 VB_Code 放到前面

windows 2008R2 大量工作排程的匯出備份以及匯入
由於工作排程往往有數十個甚至百來個 因此需要一個方法能快速備份及移轉到其他 server 的方法
查了一下,好像也只能這樣做

---- 使用指令把全部排程匯出 ----
參考網址
https://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396

schtasks /query /XML > all_tasks.xml  
schtasks /query /FO CSV /V >sched_tasks.csv

** xml 比較有用,可以用來匯入到其他server排程,但還要額外處理才能匯入
** csv 只是用來看看目前有哪些排程 可以用來做報表看看
** 這些是全部排程,還要特別處理把 Microsoft 及其他軟體建的排程移除

--------------------------------------------------------------

----如何匯入工作排程到其他 server --------

** 需再寫程式把 all_tasks.xml 拆解成所有排程的單一 xml
   並且生成指令 bat

** 注意 xml 必須是 UTF-16 (unicode) 
   因為 "schtasks /query /XML > all_tasks.xml"產生 xml 是 ansi 

參考網址
https://serverfault.com/questions/325569/how-do-i-import-multiple-tasks-from-a-xml-in-windows-server-2008
** /TN "排程名稱" --- 排程名稱可以是路徑名 
D:\>schtasks.exe /create /TN "\2016JOB\Global\CountryMonthlyStats" /XML "D:\one_task.xml"
** 下面程式碼只是下面程式碼只是參考 還沒實作過
=====================================

var taskXML = new XmlDocument();
taskXML.Load(@"d:\temp\schedtasksBackup.xml");
var batbody = new StringBuilder();

XmlNodeList tasks = taskXML.DocumentElement.GetElementsByTagName("Task");

string strFileName = "d:\\temp\\Task";

for (int i = 0; i < tasks.Count; i++) {
    string onetaskXML = tasks[i].OuterXml;

    //Create the New File. With a little more extra effort
    //you can get the name from a comment above the task -> 應該把註解裡的名稱抓出
    XmlWriter xw = XmlWriter.Create(strFileName + "_" + (i+1) + ".xml");
    batbody.AppendLine(string.Format("schtasks.exe /create /TN \"{0}\" /XML \"{1}\"", "Task " + (i+1) + " Name", strFileName + "_" + (i+1) + ".xml"));

    //Write the XML
    xw.WriteRaw(onetaskXML.ToString());
    xw.Close();

    // Write a bat to import all the tasks
    var batfile = new System.IO.StreamWriter("d:\\temp\\importAllTasks.bat");
    batfile.WriteLine(batbody.ToString());
    batfile.Close();

}
=====================================

還原資料庫後不用刪除帳號再新增的方法 (SQL User)
先在 Server 上面建立好同名的帳號, 然後可以用這個指令

sp_change_users_login 'Auto_Fix', 'username'


若想要連 Server 上的帳號一併建立: 

sp_change_users_login [ @Action = ] 'action'
    [ , [ @UserNamePattern = ] 'user' ]
    [ , [ @LoginName = ] 'login' ]
    [ , [ @Password = ] 'password' ]
[;]

[ @Action= ] 'action'
描述此程序所要執行的動作。 動作是varchar (10)。 通常是 'Auto_Fix'

[ @UserNamePattern= ] 'user'
這是目前資料庫中的使用者名稱。 使用者是sysname,預設值是 NULL。
[ @LoginName= ] 'login'
這是 SQL Server 登入的名稱。 登入是sysname,預設值是 NULL。
[ @Password= ] 'password'
指派給新的密碼SQL Server藉由指定建立登入Auto_Fix。 如果符合的登入已經存在,對應的使用者和登入和密碼會被忽略。 如果符合的登入不存在,則 sp_change_users_login 會建立新SQL Server登入,並指派密碼當做新登入的密碼。 密碼是sysname,而且不可以是 NULL。

簡單的 HTTP Relay By MVC.
客戶要求
1. 檔案只能放在 Firewall 內的後台用 Web server (Server A).
2. 使用者只能存取 DMZ 的 Web server (Server B).
3. Server B 只能用 HTTP 通過 Firewall 向 Server A 要資料.(i.e.  Server B 不能掛戴 Server A 的目錄成為虛擬目錄)

所以在 Server B 上面建立了一支程式用 HTTP 的方式讀取 Server A 的檔案再寫出去.

例如, http://ServerB/Upload/test.pdf 會讀取 http://ServerA/Upload/test.pdf 再送到 Client 端

namespace WWW.Controllers
{
    public class UploadController : Controller
    {
        // GET: Upload
        public void Index(string Filename)
        {
            //Create a stream for the file
            Stream stream = null;

            //This controls how many bytes to read at a time and send to the client
            int bytesToRead = 10000;

            // Buffer to read bytes in chunk size specified above
            byte[] buffer = new Byte[bytesToRead];

            string url = "http://admin-dev.nanya.bike.idv.tw/newnanyaback/Upload/" + Filename;

            // The number of bytes read
            try
            {
                //Create a WebRequest to get the file
                HttpWebRequest fileReq = (HttpWebRequest)HttpWebRequest.Create(url);

                //Create a response for this request
                HttpWebResponse fileResp = (HttpWebResponse)fileReq.GetResponse();

                if (fileReq.ContentLength > 0)
                    fileResp.ContentLength = fileReq.ContentLength;

                //Get the Stream returned from the response
                stream = fileResp.GetResponseStream();

                // prepare the response to the client. resp is the client Response
                var resp = HttpContext.Response;

                if (Filename.ToLower().EndsWith(".png") ||
                    Filename.ToLower().EndsWith(".jpg") ||
                    Filename.ToLower().EndsWith(".jpeg") ||
                    Filename.ToLower().EndsWith(".gif")
                    )
                {
                    resp.ContentType = "image";
                }
                else
                {
                    //Indicate the type of data being sent
                    resp.ContentType = "application/octet-stream";

                    //Name the file
                    resp.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(Filename, Encoding.UTF8) + "\"");
                }

                resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());

                int length;
                do
                {
                    // Verify that the client is connected.
                    if (resp.IsClientConnected)
                    {
                        // Read data into the buffer.
                        length = stream.Read(buffer, 0, bytesToRead);

                        // and write it out to the response's output stream
                        resp.OutputStream.Write(buffer, 0, length);

                        // Flush the data
                        resp.Flush();

                        //Clear the buffer
                        buffer = new Byte[bytesToRead];
                    }
                    else
                    {
                        // cancel the download if client has disconnected
                        length = -1;
                    }
                } while (length > 0); //Repeat until no data is read
            }
            finally
            {
                if (stream != null)
                {
                    //Close the input stream
                    stream.Close();
                }
            }
        }
    }
}



但不是這樣就好了, 在 RouteConfig.cs 中要加上:
            routes.MapRoute(
                name: "Upload",
                url: "Upload/{filename}",
                defaults: new { controller = "Upload", action = "Index", filename = UrlParameter.Optional }
            );

此外在 Web.Config 中也要加上:

  <system.webServer>
    <handlers>
      <add name="UrlRoutingHandler_Upload"
           type="System.Web.Routing.UrlRoutingHandler, 
               System.Web, Version=4.0.0.0, 
               Culture=neutral, 
               PublicKeyToken=b03f5f7f11d50a3a"
           path="/Upload/*"
           verb="GET"/>
    </handlers>
  </system.webServer>

Application_BeginRequest 沒有作用, windows 2008, IIS7, MVC,
在 windows  2008 的 IIS7 跑 MVC, 會遇到 Application_BeginRequest 沒有作用, 可以在 web.config 中加一個:

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" />
</system.webServer>

另外聽說裝 KB980368 會是比較好的解決方法, 有空再來試試.

      Debug.WriteLine(convString); //黑暗执行绪&#29319;ABC123
      var resultString = fromNCR(convString);
      Debug.WriteLine(resultString); //黑暗执行绪犇ABC123


    static string toNCR(string input)
    {  
      StringBuilder sb = new StringBuilder();
      Encoding big5 = Encoding.GetEncoding("big5");
      foreach (char c in input)
      {
        //強迫轉碼成Big5,看會不會變成問號
        string cInBig5 = big5.GetString(big5.GetBytes(new char[] {c}));
        //原來不是問號,轉碼後變問號,判定為難字
