UW -> DB 物件產生器會產生兩個function
GetAllDataFromBaseTableWithCache(string OrderFields = "_Default", bool IsCopy = true )
以及
Get物件名稱FromCachedDT(string Key)
-----------------------------------------------------------
設計上是希望將所有資料Cache在記憶體，然後前端直接抓出資料，不須到資料庫抓資料
理論上網頁速度應該比較佳，實際上卻發現是效能殺手

原因在於 GetAllDataFromBaseTableWithCache 是抓出整個table的資料放到 Cache
然後又做了一件事，當有人要資料時，會把整個 DataTable 做 Copy() 再 return
也就是說，當DataTable有數千筆資料列時
每叫用一次 "Get物件名稱FromCachedDT(string Key)" 就會把數千筆資料整個複製一次
再從複製出來的DataTable Select 出一列 return
------------------------------------------------------------
解決方法:
Get物件名稱FromCachedDT(string Key)  --> 改成一筆一筆資料做 Cache，這樣 Copy() 只會Copy一筆
實測上，原本頁面要跑1.8秒，調整後可以 0.4 秒就完成
-----------------------------------------------------------
結論:
PG產生器就把 GetAllDataFromBaseTableWithCache 拿掉吧

點選開始結帳卻發現觸發後面商品數量的select按鈕
若select z-index=200 則蓋在上面的按鈕則z-index=201
上面的z-index要比下面的z-index大
就可以解決了

1. Go into the Properties window for the project where you want to see stack trace line numbers.
2. Click on the Build "vertical tab".
3. Select "Release" configuration. Check the DEBUG constant parameter.
4. Uncheck the "Optimize code" parameter to avoid the occasional trace issue with inlined code (this step is not essential).
5. Press the Advanced... button and choose Output -> Debug Info -> pdb-only.
6. Deploy the generated .pdb file with the assembly.

 
 
 

轉換文章內容成為excel 檔案的時候
發生的錯誤
網路上查都好像是跟圖片有關的錯誤
後來才確認是 emoji 的問題
文章裡有出現

🙋‍♀️🙋‍♀️🙋‍♀️

這種東西 

SQL:
SQL 好像也沒辦法完美的取代 ( 如果有辦法對準是哪個字元就可以 但如果是一個字串好像會無法取代)
只有剛好對到那個字元開頭時才能換
NCHAR(65039)  NCHAR(8205)

Select TOP 10 
Replace(SUBSTRING(content,10,15),NCHAR(65039) ,'XX') ,                                    ---HongKong‍️‍️‍️🙋‍♀️怎
REPLACE(SUBSTRING(content,17,8),NCHAR(65039),'OO')                                        ---OO怎 
FROM [Table] 


C#
最後回到C#來處理
首先用 把string  .ToArray() 變成char
找出字元後 轉成 int 來確認要怎麼表達這個 char
最後結果就變成>>
Convert.ToInt32(Table.Rows[0]["Content"].ToString().ToArray());
之後直接變成 char去取代
row["mycolumn"].ToString().Replace((char)65039, ' ').Replace((char)8205, ' ');
然後就暫時 沒錯誤了
只是這網站一直再更新
https://emojipedia.org/unicode-12.0/

所以未來可能還會有新的問題
目前還不知道甚麼快速的解法







 

修改欄位設定時，出現需要刪除資料表(drop table)再建立資料表(create table)才能修改時，
於 [工具] > [選項] > [設計工具]
清除防止儲存需要重新建立資料表的變更] 核取方塊，即可。

<範例>
Table: [員工資料表]
欄位: [主管], [員工]

需求是: 當輸入一個員工姓名, 要把該員工下面所有階層的員工都Show出來

SQL語法:
 

WITH [員工資料表new] AS (

--找出 [主管] 為 某人的資料當作 依據

SELECT [主管], [員工]

FROM [員工資料表]

WHERE [主管] = 'XXXX'



UNION ALL



--之後以 上面查出的結果 為依據遞迴查詢

SELECT e.[主管], e.[員工]

FROM [員工資料表] e

INNER JOIN [員工資料表new] ecte ON ecte.[員工] = e.[主管]

)

SELECT *

FROM [員工資料表new]

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
