都牽涉到後台使用者及前台User看訂單時間錯誤問題
因為系統時間是TW的時間而操作者是外國的使用者 這就需要有個方便模組來轉換系統時間以及user的時間顯示
這部分我以 Extension Method 方式來處理
in VB
Imports System.Runtime.CompilerServices Imports Microsoft.VisualBasic Public Module DateTimeExtension ''' <summary> ''' 將系統時間轉為當地的時間並轉為字串 ''' </summary> ''' <param name="dtSystem"></param> ''' <returns></returns> ''' <remarks></remarks> <Extension()> _ Public Function ToCountryDateTimeString(ByVal dtSystem As DateTime) As String If dtSystem = DateTime.MinValue Then Return "n/a" End If Dim cstTime As DateTime = dtSystem.ToCountryDateTime() ' tr-TR -> dd.MM.yyyy HH:mm:ss Dim langCode As String = SHOPUNT.DB.SysConfig.GetSysConfig("DefaultLangCode") Dim culture As New System.Globalization.CultureInfo(langCode) If cstTime.AddMonths(6) < Now Then Return cstTime.ToString("dd.MM.yyyy HH:mm", culture) Else Return cstTime.ToString("dd.MMM HH:mm", culture) End If End Function ''' <summary> ''' 將系統時間轉為當地的時間 ''' </summary> ''' <param name="dtSystem"></param> ''' <returns></returns> ''' <remarks></remarks> <Extension()> _ Public Function ToCountryDateTime(ByVal dtSystem As DateTime) As DateTime Dim cstZone As TimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(SHOPUNT.DB.SysConfig.GetSysConfig("DefaultTimeZone")) Dim localZone As TimeZoneInfo = TimeZoneInfo.Local Dim cstTime As DateTime = TimeZoneInfo.ConvertTime(dtSystem, localZone, cstZone) Return cstTime End Function ''' <summary> ''' 將使用者輸入的時間轉為系統時間 ''' </summary> ''' <param name="dtCountry"></param> ''' <returns></returns> ''' <remarks></remarks> <Extension()> _ Public Function ToSystemDateTime(ByVal dtCountry As DateTime) As DateTime Dim cstZone As TimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(SHOPUNT.DB.SysConfig.GetSysConfig("DefaultTimeZone")) Dim localZone As TimeZoneInfo = TimeZoneInfo.Local Dim sysTime As DateTime = TimeZoneInfo.ConvertTime(dtCountry, cstZone, localZone) Return sysTime End Function End Module使用上 只要
DateTime.Now.ToCountryDateTime() 就可以把系統時間轉換成user時間
相反的也有把 user時間轉換成系統時間的功能 ToSystemDateTime()
英國的TimeZone: GMT Stanard Time
Turkey的TimeZone: Turkey Stanard Time
以上的值可以用 TimeZoneInfo.GetSystemTimeZones() 找出來
1. 在網址列，同網址再按一下 Enter 載入時，Chrome 會對相同的網址再次送出 request。
2. 若是點選頁面中的連結或是在網址列輸入其它網址，才有可能看到 200 (From Cache)
在情況 1 時，若是有使用 Response.Cache.SetLastModified(Now) 則會看到 304 ，否則會把 Script 重新載入一次。
所以在 Server 最佳的(我覺得)寫法是:
Response.Cache.SetCacheability(HttpCacheability.Private)
Response.Cache.SetExpires(Now.AddYears(1)) '一年後才會到期，沒有這個就不會有 200 (From Cache)
Response.Cache.SetLastModified(Now) '若是 Browser 送出了一個新的 Request, 有可能會回 304
不過有趣的是，在 scripts.aspx 收到帶有 If-Modified-Since 的 Request 時，是怎麼判斷要回應 304 的，我在 .vb 裡面沒有加上這個處理吔。
因為ASP.NET4.0與2.0版本在請求驗證的定義上已經有所不同：
這時為了避免這樣的問題，一樣在Web.Config中 <system.web>下加入下列語句
<httpRuntime requestValidationMode="2.0" />

修改的位置如下圖，把 ipSecurity 的 overrideModeDefault 改為 Allow:
HttpApplication Events:
Application_AcquireRequestState
Occurs when ASP.NET acquires the current state (for example, session state) that is associated with the current request.
Application_AuthenticateRequest
Occurs when a security module has established the identity of the user.
Application_AuthorizeRequest
Occurs when a security module has verified user authorization.
Application_BeginRequest
Occurs as the first event in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Application_Disposed
Adds an event handler to listen to the Disposed event on the application.
Application_EndRequest
Occurs as the last event in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Application_Error
Occurs when an unhandled exception is thrown.
Application_PostAcquireRequestState
Occurs when the request state (for example, session state) that is associated with the current request has been obtained.
Application_PostAuthenticateRequest
Occurs when a security module has established the identity of the user.
Application_PostAuthorizeRequest
Occurs when the user for the current request has been authorized.
Application_PostMapRequestHandler
Occurs when ASP.NET has mapped the current request to the appropriate event handler.
Application_PostReleaseRequestState
Occurs when ASP.NET has completed executing all request event handlers and the request state data has been stored.
Application_PostRequestHandlerExecute
Occurs when the ASP.NET event handler (for example, a page or an XML Web service) finishes execution.
Application_PostResolveRequestCache
Occurs when ASP.NET bypasses execution of the current event handler and allows a caching module to serve a request from the cache.
Application_PostUpdateRequestCache
Occurs when ASP.NET completes updating caching modules and storing responses that are used to serve subsequent requests from the cache.
Application_PreRequestHandlerExecute
Occurs just before ASP.NET begins executing an event handler (for example, a page or an XML Web service).
Application_PreSendRequestContent
Occurs just before ASP.NET sends content to the client.
Application_PreSendRequestHeaders
Occurs just before ASP.NET sends HTTP headers to the client.
Application_ReleaseRequestState
Occurs after ASP.NET finishes executing all request event handlers. This event causes state modules to save the current state data.
Application_ResolveRequestCache
Occurs when ASP.NET completes an authorization event to let the caching modules serve requests from the cache, bypassing execution of the event handler (for example, a page or an XML Web service).
Application_UpdateRequestCache
Occurs when ASP.NET finishes executing an event handler in order to let caching modules store responses that will be used to serve subsequent requests from the cache.
Application_Init
This method occurs after _start and is used for initializing code.
Application_Start
As with traditional ASP, used to set up an application environment and only called when the application first starts.
Application_End
Again, like classic ASP, used to clean up variables and memory when an application ends.
Session Events:
Session_Start
As with classic ASP, this event is triggered when any new user accesses the web site.
Session_End
As with classic ASP, this event is triggered when a user's session times out or ends. Note this can be 20 mins (the default session timeout value) after the user actually leaves the site.
Profile Events:
Profile_MigrateAnonymous
Occurs when the anonymous user for a profile logs in.
Passport Events:
PassportAuthentication_OnAuthenticate
Raised during authentication. This is a Global.asax event that must be named PassportAuthentication_OnAuthenticate.
Possibly more events defined in other HttpModules like:
System.Web.Caching.OutputCacheModule
System.Web.SessionState.SessionStateModule
System.Web.Security.WindowsAuthentication
System.Web.Security.FormsAuthenticationModule
System.Web.Security.PassportAuthenticationModule
System.Web.Security.UrlAuthorizationModule
System.Web.Security.FileAuthorizationModule
System.Web.Profile.ProfileModule

<div id="divContent" style="border:1px solid black">ABCDE</div>
--> 寬divContent 的度隨內文變化
<div style="width:1000px"><div id="divContent" style="border:1px solid black">ABCDE</div></div>
--> divContent 的寬度會和父容器相同
原來 display 為 block 的物件的寬度都會和父容器相同, 把 display Mode 改為 inline 即可.
<div style="width:1000px"><div id="divContent" style="border:1px solid black; display:inline">ABCDE</div></div>
--> divContent 的寬度會和父容器相同
但 inline 的物件後方可能會跟了些不讓跟的東西, 所以可能要加個 <br> 比較好.
※修改主目錄web.config
刪除(紅字)
＊<compilation debug="true" targetFramework="4.0">
＊<httpRuntime maxRequestLength="102400" requestValidationMode="2.0"></httpRuntime>
※修改虛擬目錄web.config
加上<remove assembly="...." />
1.如果网站程序不需要ASP.NET 4.0 的支持，那么可以直接配置网站使用ASP.NET 2.0。
2.如果网站程序需要ASP.NET 4.0的支持，就需要将该网站下使用ASP.NET 2.0的虚拟目录移动到其他网站。
3.如果上面两种方法都不适用于你的实际情况，那么就只能用这种方法了：
打开注册表找到“HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\ASP.NET\\4.0.30319.0”
添加键值名为“EnableExtensionlessUrls” 类型为“DWORD”的键值
并设置值为"0"
然后在cmd中运行“IISRESET”，重启IIS以读取注册表修改后的内容。
(重啟該應用程式集區即可)：
注：此项修改就是关闭ASP.NET 4.0对无扩展URL的处理，若将此项键值设为“1”则开启。
參考：http://www.webjx.com/aspnet/2011-04-02/29024.html
A potentially dangerous Request.Form value was detected from the client (ContentBody_txtContent="<style type="text/cs...").
.aspx新增了<%@ Page validateRequest="false"%>
最後找到還需要在web.config裡面新增<httpRuntime requestValidationMode="2.0" />
