Visual Studio 預設發佈的模式是不包括錯誤行號的. 要開啟在這裡設定:



還有 option 要設定:

 
 

想到的先列出來.

1. 幫 String 擴充屬性(javascript, .NET)
2. SQL Injection.
3. Cross Site Script Attack.
4. 避免排程未完全執行以及重覆執行.
5. 更新 Cache 與 Lock.
6. SQL Transaction.
 

不要自動加 "s"

 

先留個言, 有空來補內容.

VB
Public Module SqlStringExtention

    <Extension()>
    Function SQLStr(ByVal Original As String) As String
        Return Original.Replace("'", "''")
    End Function

    <Extension()>
    Function SQLTrim(ByVal Original As String) As String
        Return Original.Trim.Replace("'", "''")
    End Function

End Module

C#
//Extension methods must be defined in a static class
    public static class StringExtension
    {
        /// <summary>
        /// 把 ' 取代成 ''
        /// </summary>
        /// <param name="value"></param>
        /// <returns></returns>
        public static string sqlStr(this string value)
        {
            return value.Replace("'", "''");
        }

        /// <summary>
        /// 假設欄位名稱中不會有 [ 或 ] 的符號
        /// </summary>
        /// <param name="value"></param>
        /// <returns></returns>
        public static string sqlField(this string value)
        {
            return "[" + value.Replace("[", "").Replace("]", "") + "]";
        }
    }

LEN: 不會計入空白結尾. DATALENGTH: 實際的長度.

突然發現 yahoo 不支援 SSL3.0 或 TLS 1.0 了, 要改用 TLS 1.2 才抓的到網頁資料

​

            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

            ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

.Net 4.0 在抓網頁之前先加這兩行, 就可以了. 

.Net 4.5 支援 Tls12, 可以用 

​

            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

​

 

        var TotalOldQty = 0;

        $(".AdjQty_" + yano + "_" + pdno + " [type='text']").each(function () {

            TotalOldQty += parseInt($(this).data("oldqty"));

        });



        $(".AdjQty_" + yano + "_" + pdno).html($(".AdjQty_" + yano + "_" + pdno).html() + "更新中.....");



        $(".AdjQty_" + yano + "_" + pdno + " span").hide();

和 

        $(".AdjQty_" + yano + "_" + pdno).html($(".AdjQty_" + yano + "_" + pdno).html() + "更新中.....");



        $(".AdjQty_" + yano + "_" + pdno + " span").hide();



        var TotalOldQty = 0;

        $(".AdjQty_" + yano + "_" + pdno + " [type='text']").each(function () {

            TotalOldQty += parseInt($(this).data("oldqty"));

        });

出來的 TotalOldQty 會不相同..

自從上次調整 server 2008 R2 SSL 設定之後
http://blog.uwinfo.com.tw/auth/article/darren/324
調整一堆reg設定, 好不容易最後到達 A 等級

然而最近讓一家PCI認證公司做弱點掃描，他要求我把 3DES 及 TLS1.0關掉  才肯給證書
於是我就調整以下的 reg

Windows Registry Editor Version 5.00



[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\Triple DES 168]

"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\SecurityProviders\Schannel\Protocols\TLS 1.0\Server]

"Enabled"=dword:00000000

重開機，發生一個小災難，就是遠端登入(RDP) 進不去，查了一下，發現是 server2008 R2 的遠端登入是 TLS 1.0 連線
需要上 KB3080079 才能解決，但遠端都進不去了，要如何 patch
本來想說跑一趟機房，但太麻煩，於是上網查一下，發現其實可以用 PS command 方式做遠端 windows update
幸好網路上有一些這種UI工具可以做遠端管控  例如  batchpatch 
於是下載執行遠端作 patch 之後，重開機就可以遠端登入啦，省了跑機房的功夫

題外話  batchpatch 這工具蠻不錯的 

LINE Pay款流程： 
reserve Page(紅科) 發送 reserve API => 取得 payment URL => 轉址到 payment URL => LINE Pay 檢查USER狀態 => 轉回confirm page(紅科), 發送 confirm API => DOWN.

#專案： 紅科

使用 SQL Server 管理介面設定欄位權限時要很小心陷井. 如下圖,
1. Col2 和 Id 欄位沒有被授予也沒有被拒絕.
2. 若是設定 Col2 欄位為授予, Id 欄位沒有做任何的修改.
3. 存檔後, Id 欄位會被拒絶存取.

 
以上的情況是用以下 SQL 生成:

GRANT SELECT ON OBJECT::S3..test TO webuser;
Deny SELECT ON OBJECT::S3..test(Col1) TO webuser;
