記得當初不知到是誰告訴我 WIN7 不支援 Telnet , 因為也不常用,所以都用 pietty 代替,
一直到這兩天在測postfix , 一直用到 , 想找回 CMD 的使用方式 , 沒想到設定一下就好了

內建RAID主機版再造無法安裝LINUX 問題
今天要 CentOs 來跑 mailserver ,不知到為什麼一直裝不進去 , 一開始為RAID沒驅動的關係,後來該關的都關了,還是一樣,只好請示google 大神
錯誤訊息:
"Disk sda contains BIOS RAID metadata, but is not part of any recognized BIOS RAID sets. Ignoring disk sda"
我試了二塊版子 , 分別是 sb710 跟 ich7 , 二片都一樣 , 查的結果應該是 fakeraid 的問題 , 也就是MB內建RIAD 的問題,並不是真正的RAID卡,解決方法也不難, 只要在安裝光碟的第一個畫面按下 TAB鍵 在啟動命令 輸入:
"linux nodmraid"
再 Enter 進行安裝就可以解決這個問題.
Asp.Net 手工進行資料庫的新增、查詢、修改
Asp.Net 雖然有很多工具可以做到零程式碼 ,就能完整的撈出資料 , 但是有些功能還是手工 "卡實在"
第一件事是要引用 web.config 裡的連接語法 , 如果還沒有做的 , 請手工KEY進去 , 或建一個 SqlDataSoure ,VS 會幫你建好

MSSQL CTE 遞迴查詢結構
遞迴 CTE 結構至少必須包含一個錨點成員與一個遞迴成員。下列虛擬程式碼顯示含有單一錨點成員與單一遞迴成員的簡單遞迴 CTE 所具備的元件。

|
1 |
<span style="color: #606060" id="lnum10"> 10:</span> <span style="color: #0000ff">FROM</span> cte_name |
遞迴執行的語意如下：
將 CTE 運算式分割為錨點成員與遞迴成員。
執行錨點成員以建立第一個引動過程或基底結果集 (T0)。
執行遞迴成員，以 Ti 做為輸入，而以 Ti+1 做為輸出。
重複步驟 3，直到傳回空的結果集為止。
傳回結果集。這是 T0 至 Tn 的 UNION ALL。

<span style="color: #606060" id="lnum14"> 14:</span> <span style="color: #0000ff">from</span> directsales |
所以錨點成員是
select up_dno,dno,1 as lvl from dbo_dsales where dno='A'
也就是
up_dno,dno,lvl
null Ａ １
那遞迴成員是
select a.up_dno,a.dno,lvl+1 from dbo_dsales a,directsales b where a.up_dno=b.dno
也就是
在第一次跑時,b.dno = A
得到
up_dno,dno,lvl
Ａ Ｂ ２
Ａ Ｃ ２
在第二次跑時,b.dno = B,C
得到
up_dno,dno,lvl
Ｂ Ｄ ３
Ｂ Ｅ ３
Ｃ Ｆ ３
Ｃ Ｇ ３
Ｃ Ｈ ３
在第三次跑時,b.dno = D,E,F,G,H
得到
up_dno,dno,lvl
Ｄ Ｉ ４
Ｄ Ｊ ４
Ｆ Ｋ ４
Ｇ Ｌ ４
在第四次跑時,b.dno = I,J,K,L
得到
up_dno,dno,lvl
Ｊ Ｍ ５
Ｌ Ｎ ５
在第五次跑時,b.dno = M,N
得到 無符合資料(傳回空的結果集)
所以遞迴停止
所以最後得到結果為
up_dno,dno,lvl
null Ａ １
Ａ Ｂ ２
Ａ Ｃ ２
Ｂ Ｄ ３
Ｂ Ｅ ３
Ｃ Ｆ ３
Ｃ Ｇ ３
Ｃ Ｈ ３

Word 異常還原設定
難得用到一個 微軟提供的方法是有效的 !!
http://support.microsoft.com/kb/822005/zh-tw
如果要自動修正此問題，請按一下 [Fix it] 按鈕或連結，然後在 [檔案下載] 對話方塊中按一下 [執行]，並依照「Fix it 精靈」中的步驟執行。
使用 微軟提供的 FIX
Microsoft Fix it 50599 重設 Word 中的使用者選項
範本問題以前有遇過 , 沒想到這次也看到正確解法
通用範本 (Normal.dotm 或 Normal.dot)
如果要避免通用範本 (Normalm.dot 或 Normal.dot) 中儲存的格式變更、自動圖文集項目和巨集影響 Word 和開啟文件的行為，請重新命名通用範本 (Normal.dotm 或 Normal.dot)。重新命名範本可以讓您迅速判斷問題是否由通用範本所造成。
在 Word 2007 或更新版本中重新命名 Normal.dot 範本，或是在 Word 2003 和舊版 Word 中重新命名 Normal.dot 範本時，會將數個選項重設回預設設定。這些重設的選項包括自訂樣式、自訂工具列、巨集和自動圖文集項目。我們強烈建議您不要刪除 Normal.dotm 或 Normal.dot 範本，而只重新命名範本。如果您確定問題源自範本，則可從重新命名的 Normal.dot 範本複製自訂樣式、自訂工具列、巨集和自動圖文集項目。
某些類型的組態可能會建立多個 Normal.dotm 或 Normal.dot 範本。這些情況包括：在同一部電腦上執行多種 Word 版本，或在同一部電腦上存有數種工作站安裝。在這些情況下，請確定您重新命名的是正確的範本。
如果要重新命名通用範本檔案，請依照下列步驟執行：
- 結束所有 Office 程式。
- 按一下 [開始]，按一下 [執行]，輸入 cmd，然後按一下 [確定]。
- 根據您執行的 Word 版本輸入下列命令，然後按下 ENTER：
- Word 2002 和 Word 2003：
ren %userprofile%\Application Data\Microsoft\Templates\Normal.dot OldNormal.dot - Word 2007 和 Word 2010：
ren %userprofile%\Application Data\Microsoft\Templates\Normal.dotm OldNormal.dotm
- Word 2002 和 Word 2003：
- 輸入 exit，然後按下 ENTER
