vs 2010 加快編譯速度

VSSpeedster - Speed up your VS 2010
!Installation:
#. Extract all the files from this archive to the following folder:
C:\Users\UserName\Documents\Visual Studio 2010\AddIns
#. Restart VS
#. Open Tools->Addin Manager
#. Enable VSSpeedster in the Addin Manager (first and second column checkboxes)
#. Now you should get a new button on the "Build" toolbar "Parallel Builds" (icon looks like two parallel lines)
#. Any Build/Run operation will not be run as a parallel build.
You can Turn On/Off the Parallel builds by clicking on the Parallel Builds.

利用 xcopy 指令備份資料，並設定排程自動備份

一、Xcopy 常用參數簡介：

/M 只複製設定成保存屬性的檔案，並清除保存屬性。
/S 複製每個目錄及其包含的子目錄，不複製空目錄。
/O 複製檔案所有權及 ACL 資訊。
/C 如果錯誤發生時也繼續複製。
/I 如果目的不存在且複製一個以上的檔案的話，就假設指定的目的一定是目錄。
/H 複製隱藏檔和系統檔。
/K 複製檔案屬性。通常 Xcopy 會重設唯讀的屬性。
/Y 不要提示您確認是否要覆蓋一個已經存在的檔案。
/Q 在複製時不要顯示檔名。

二、備份範例：
Xcopy d:\share e:\backup /M /S /O /C /I /H /K /Y /Q

以上指令是將【D:】磁碟内 share 資料夾完整的複製到【E:】磁碟的 backup 資料夾內，複製時使用增量備份方式（只備份新增或有變更的檔案），且所有檔案的安全權限保持不變。另外，如果路徑中有空白字元或中文字元，且實際測試時無法正確複製，可試試在兩頭使用雙引號，如下：
Xcopy "C:\Documents and Settings\yang\Favorites" "e:\backup" /M /S /O /C /I /H /K /Y /Q
或
Xcopy "d:\share\公共文件" "e:\backup" /M /S /O /C /I /H /K /Y /Q
以上指令使用記事本輸入後，必須儲存成【BAT】批次檔，才能正常運作。

三、排程設定：
請依序如以下圖示操作，要注意的是第七個步驟要求輸入使用者名稱及密碼，其中密碼需要事先設定好，且一定要輸入，否則排定的工作將無法執行！

在windows下定期制作備份mysql的指令碼

參考來源

程式碼:--------------------------------------------------------------------------------
Dim fName,tNow,CMD
tNow = Now()
fName = Year(tNow) & FormatNumber(Month(tNow)/100,2,false) & FormatNumber(Day(tNow)/100,2,false) & FormatDateTime(tNow,3)
fName = Replace(Replace(fName,".",""),":","")
CMD = ""
CMD = CMD & "c:" & vbCrLf
CMD = CMD & "cd c:\mysql\bin" & vbCrLf
CMD = CMD & "mysqldump -u root -p""password"" vbb>d:\bbsbak\backup" & fName & ".sql"
Dim FileObject,BatFile,BatPath
Set FileObject = CreateObject("Scripting.FileSystemObject")
BatPath = "d:\bbsbak\backup.bat"
Set BatFile = FileObject.CreateTextFile(BatPath, True)
BatFile.WriteLine(CMD)
BatFile.Close
Set BatFile = Nothing
Set FileObject = Nothing
Set WshShell = CreateObject("Wscript.Shell")
WshShell.Run BatPath,1,true
Set WshShell = Nothing
--------------------------------------------------------------------------------


把以上程式碼存為backup.vbs,然後你用windows內已含有計劃工作來實現制作備份就行

--opt

制作備份的時候要加上這個參數.....恢復的時候就方便了...對比一下產生的dump文件就會發現增加了那些了...

恢復很簡單...

mysql -u root -p dbname

然後會提示你密碼...

Dim a As String = "統一鮮乳 &42 TX"
Dim b As String = ""
TextBox1.Text += a.Length.ToString + vbCrLf
Dim a_insert As Integer = InStr(a, "TX") - 2
TextBox1.Text += a_insert.ToString + vbCrLf
b = Mid(a, 1, a_insert) + "-" + Mid(a, InStr(a, "TX"), a.Length - InStr(a, "TX") + 1)
TextBox1.Text += b

有很完整的說明
我照著做都解決了

一個簡單的方法是：
Sql = "select * From [tbname] Where Title like ’%"&keyword&"%’ Order By id Desc"
換成：
Sql = "select * from [tbname] where InStr(1,LCase(Title),LCase(’"&keyword&"’),0)<>0 order by id desc"

我想以後會考慮用utf-8
因為即便只使用中文的web-based資料庫系統
也經常發生很多big5無法支援的特殊字或古字
像很多人的名字因為是特殊字
就無法正確建立基本資料
用utf-8可以解決這些問題
甚至可以用多國語言

**注意**

若有utf-8中文參數值要透過url傳遞時
記得先用Server.URLEncode()把中文參數值編碼
接收參數時不用任何修改會自動解碼

不過要透過URL傳遞參數
建議最好還是使用英文和數字

How to Repair MDAC 2.8 Under Windows XP SP2/SP3
General Information
Windows XP with Service Pack 2 or 3 contains MDAC version 2.81, which is currently not available for download at the Microsoft Web site as a standalone installation. If you try to install MDAC 2.8, which is the latest available standalone download of MDAC, you will receive a message that you already have a newer version of MDAC installed. Therefore, under Windows XP SP2/SP3, you must manually repair MDAC 2.81 as outlined below.

How to Repair MDAC 2.81 under Windows XP with SP2 or SP3
1. In Windows Explorer, open the c:\Windows\Inf folder.

Note If you cannot see the c:\Windows\Inf folder, follow these steps: a. On the desktop, double-click My Computer, and then on the Tools menu, click Folder Options.
b. Click the View tab.
c. Under Advanced settings, select the Show hidden files and folders check box.
d. Clear the Hide extensions for known file types check box.
e. Click OK.


2. In the C:\Windows\Inf folder, right-click the Mdac.inf file, and then click Install.

3. When you are prompted to insert the Windows XP SP2 CD, use one of the following methods: I. If you have a Windows XP SP2 CD:
a. Insert the Windows XP Service Pack 2 CD in the CD or DVD drive.
Note If a "Welcome to Microsoft Windows XP" message appears, click Exit.
b. Click Browse.
c. In the File name box, type CD or DVD drive that contains the Windows XP Service Pack 2 CD drive letter:\i386. For example, type d:\i386 if the Windows XP Service Pack 2 CD is in drive D.
d. Click Open.

II. If you do not have a Windows XP SP2/SP3 CD:
a. In the File name box, type %systemroot%\windows\servicepackfiles\i386, and then click Open.
b. When prompted for adcjavas.inc, point to C:\Windows\servicepackfiles\i386
Note: If you cannot find this folder, put the Windows CD into your CD drive and browse for that file.
c. When prompted for the file handler.reg, either point to C:\Program Files\Common Files\System\msadc, or put the Windows XP CD in your CD-ROM drive.
d. When prompted for MDACRdMe.htm, point to C:\Program Files\Common Files\System\Ado. If this file is not present, rename the file MDACReadme.htm to MDACRdMe.htm.
e. When prompted for oledbjvs.inc, point to C:\Program Files\Common Files\System\Ole DB.
f. When prompted for mssoap1.dll, point to C:\Program Files\Common Files\MSSoap\Binaries.
g. When prompted for mssoapr.dll, point to C:\Program Files\Common Files\MSSoap\Binaries (or below its subfolders).



4. You may also be prompted for the original Windows XP CD that was originally used to install the operating system. a. Insert the Windows XP Service Pack 2 CD in the CD or DVD drive.
Note If a "Welcome to Microsoft Windows XP" message appears, click Exit.
b. Click Browse.
c. In the File name box, type CD or DVD drive that contains the Windows XP Service Pack 2 CD drive letter:\i386. For example, type d:\i386 if the Windows XP Service Pack 2 CD is in drive D.
d. Click Open.
