"build error" allowDefinition='MachineToApplication

http://msdn.microsoft.com/en-us/library/aa479312.aspx

As mentioned before, Visual Studio 2005 normally considers all files in a folder or sub-folder to be part of the Web project. By default, the conversion wizard will create a backup of your Web project in a safe location, but it is possible for the user to overwrite the default. If you put the backup folder in the Web application's folder tree, you will get this somewhat cryptic build error:

Error 1 - It is an error to use a section registered as 

allowDefinition='MachineToApplication' beyond application level

How to fix

Make sure your backup location is not in the Web application's root folder or sub-folder!

WCF 使用ASP.NET 的Session

http://silverlight.net/forums/p/23080/81722.aspx

Hello, session is a server side concept.
Silverlight runs on the client, so it has no
knowledge of the session. But you can pass some
variable from the Silverlight application to the
server via a web service. Then in the web
service, you store it as a session variable.
Later when you call another web service, you can
check the session variable and return it to the
client.

While WCF also has built-in session
support, BasicHttpBinding doesn't support that.
So you need to use ASP.NET session instead. To
enable ASP.NET session on WCF, you need to turn
on ASP.NET Compatibility. Do the following:

• In web.config, under system.serviceModel
  tag, add this line:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

• On your service class (not interface), add this attribute:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

• Now you can use ASP.NET session with the
  following syntax:

HttpContext.Current.Session["YourName"] = something;

object something = HttpContext.Current.Session["YourName"];

WCF HTTPS 出現 404 not found 的問題

最近寫了一個Siverlight 的程式 ，使用 WCF 來連接 IIS Server 上的 Service，但我發現如果是連到 http 的service 則一切正常，但是如果是連到https 就會出現 HTTP 404 Not Found 的錯誤 ，經過不斷的嘗試，終於找到答案了，原來是要在Web.config加上 basicHttpBinding 的定義， 定義如下：

<bindings>

        <basicHttpBinding>

        <!-- Configure basicHttpBinding with Transport security -- >

        <!-- mode and clientCredentialType set to None.-->

           <binding name="Binding1">

               <security mode="Transport">

                   <transport clientCredentialType="None"/>

               </security>

           </binding>

        </basicHttpBinding>

    </bindings>

重點是要將 security mode 設成 Transport，這樣使用HTTPS 來連接這個service 就可以正常了，只是原來出現的 HTTP 404 Not Found 的錯誤，真是讓人怎麼想也想不到是這個問題。

FrontPage 如何 刪去列尾的空白

可以使用 Frontpage 本身的 尋找及取代的功能

1.尋找目標設定為 :b*$

2.勾選 規則運算式(X)

3.按下[全部取代(A)] 就可以了

你也可以將這個查詢規則存檔，下次再load回來，就可以重複用囉

縮小 UpdatePanel JavaScript size

使用 asp.net 的 UpdatePanel 時, 需要一併引用 ScriptManager 這個Control ，這個Control 有一個 [ScriptMode] 的屬性，如果要讓 AJAX 的 JavaScript size 變小，可以將ScriptMode的值設成Release，這樣可以將MicrosoftAjax.js 的大小從 324KB 戲劇化的變成 88.1KB

2. Client 端的參數如果有中文 要先用 encodeURI ，將中文encode

3.如果要用JSON來傳給Client，可以使用 下面這個網站開發的 JSON class

在GridView RowDataBound 如何取得不存在GridView 內的欄位資料

實務上我們不會每次都將 DataSource 所有的欄位顯示在 GridView 裡面，但當我們需要的欄位不在GridView 上時，要如何去取得這個欄位的值呢？
答案就是在GridView RowDataBound 這個 event 傳進來的 GridViewRowEventArgs e 這個 Object：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

        {

            if (e.Row.RowType == DataControlRowType.DataRow)

            {



                //object refundAmt = DataBinder.Eval(e.Row.DataItem, "RefundAmt");

                int refundAmt = ((usp_select_NetATM_logby_TransNoResult1)e.Row.DataItem).RefundAmt;



                if (refundAmt > 0)

                {

                    object OrderInfo = e.Row.FindControl("OrderInfo");

                    if (OrderInfo != null)

                    {

                        ((Label)OrderInfo).Text += "
";

                    }

                    object RefundDetailLink = e.Row.FindControl("RefundDetailLink");

                    if (RefundDetailLink != null)

                    {



                        ((HyperLink)RefundDetailLink).NavigateUrl = "javascript:MM_openBrWindow('RefundDetail.aspx?TransNo=" + e.Row.Cells[2].Text.TrimEnd() + "','NewWindow','width=850,height=600,toolbar=no, menubar=no,location=no')";

                        ((HyperLink)RefundDetailLink).Text = "(已執行退費與沖正)";

                    }
                }

e.Row.DataItem 會存放原始DataSource 作 row databound 的資料，所以可以從這裡取的你要的欄位值，要注意的是這個DateItem 的Type 是根據你原來的DataSource而定的，所以你需要事先知道，然後轉型才可以用，偷懶一點的寫法是用DataBinder.Eval 這個Method，由.Net幫你作轉型， 只是這個方法會用到reflection 的機制，遇到大量的資料時，可能會有效能上的問題。

修改 ASP.NET culture 設定

GridView 在顯示日期時間欄位時，如果IIS是在英文的OS上，那會顯示成 MM/dd/yyyy hh:mm:ss AM 的格式，如果要顯示出中文的日期欄位，可以在 IIS 的 ASP.NET 頁籤設定，如下圖所示：

Using Nullable Types

http://msdn2.microsoft.com/en-us/library/2cf62fcy(VS.80).aspx
Examples of Nullable Types

Any value type may be used as the basis for a nullable type. For example:

int? i = 10;
double? d1 = 3.14;
bool? flag = null;
char? letter = 'a';
int?[] arr = new int?[10];

如何取得Gridview 隱藏欄位的值

在某些時候，我們會想利用Gridview的欄位來放Postback後要用到的資料，但又不想讓這些欄位顯示出來，這時候你可以在 GridView1_RowCreated 這個event，將這些欄位的visible 設成 false，如此在 Postback 時就可以取得這些欄位的值，範例如下：

if ((e.Row.RowType == DataControlRowType.Header e.Row.RowType == DataControlRowType.DataRow) && e.Row.Cells.Count>11)
{
e.Row.Cells[8].Visible = false;
e.Row.Cells[9].Visible = false;
e.Row.Cells[10].Visible = false;
e.Row.Cells[11].Visible = false;
}

1. 注意：不可以在Design time時將這些欄位的Visible設成false，因為這樣你會取得空值。
2. asp.net會將這些欄位值放在viewstate內，所以如果有些資料是不能給User看到的，就不適合這樣作，如果一定要，那你就必須將viewstate 加密。

如何在 client 端 動態修改 Custom Validator 的 error message

有User的需求是希望能用alert的方式顯示出 validator 的 錯誤訊息， Validation Summary 有一個「ShowMessageBox」property 剛好可以提供這樣的功能，但是如果你的Page上有包含 Custom Validator ， 而 Custom Validator的錯誤訊息會依據不同的條件顯示的話，如何在 client 動態修改 Custom Validator 的 error message呢?

重點就是要修改 Custom Validator Client script 的 sender dom 物件，說明如下：

function fn_myValidator(sender, args)
{
sender.innerHTML = "錯誤：" + new Date().toLocaleString();
sender.errormessage = "錯誤：" + new Date().toLocaleString();
args.IsValid = false;
}

ASP.net 會將 Custom Validator render 成一個 DOM object，其中的 errormessage 屬性就是validation summary control 顯示時會去讀的資料，因此只要在Custom Validator Client script改變這個值，validation summary就會Show 出新的 error message，但是如果你希望改變Custom Validator 本身顯示在 網頁上的 error message ， 就需要修改 Custom Validator 的 innerHTML or innerText。

可以參考以下兩串討論

消失的IIS ASP.NET Tab(頁籤)

在Windows 2003 Server 上的 IIS ASP.NET Tab ， 有時會莫名的失蹤，解決方法如下
http://jamesmckay.net/2008/01/missing-aspnet-tab-in-iis-on-windows-server-2003/

1. Stop IIS using iisreset /stop
2. Open the file C:\WINDOWS\system32\inetsrv\MetaBase.xml in Notepad.
3. Find and delete the line that says Enable32BitAppOnWin64="TRUE"
4. Restart IIS using iisreset /start
5. If you still don’t see your ASP.NET tab, aspnet_regiis -i should now work.

另外也可以用

ASP.NET Version Switcher

來取代
