大量的選擇 數(shù)據(jù)捆綁使得調(diào)用 頁面相關(guān)數(shù)據(jù)是變得非常的簡單。 在系統(tǒng)運(yùn)行時(shí),微軟文件(在 MSDN 上)申明在 DataBinder 類中將數(shù)據(jù)綁定表達(dá)式的值的數(shù)據(jù)類型強(qiáng)制轉(zhuǎn)換成實(shí)例的數(shù)值類型。 查詢的數(shù)值是通過 轉(zhuǎn)發(fā)器來控制顯示的。當(dāng)串值被返回時(shí),語法結(jié)構(gòu)仍然保持不變。 % % 串價(jià)值的一個(gè)陣列被返回。盡管如此,只要返回一個(gè)數(shù)值,這個(gè)數(shù)值表達(dá)式就被調(diào)用了。 如果你熟悉經(jīng)典 ASP,在 同。re dealing with an array of integers, the DataItem will be an integer. The following list provides a quick review of the syntax for various scenarios: % %An array of string values is returned. % (expression) %The specific field from a DataView container is returned. % %The specific string property value of data source is returned. % CStr() %Returns a property value converted to its string representation. When you39。 if ( ( , ) ) { (coverLayer) 。鼠標(biāo)選擇的腳本代碼為 : function select () { var selectedRegion:Array。 stageHeight = height。 DataAdapter 對(duì)象允許將 DataSet 對(duì)象中的數(shù)據(jù)保存到數(shù)據(jù)來源 (DataSource) , 也可以從數(shù)據(jù)來源取出數(shù)據(jù)。如果有多個(gè)用戶在同一時(shí)間對(duì)同一計(jì)算機(jī)進(jìn)行同樣的操作 , 則機(jī)器內(nèi)存將被過度使用。 DataSet 對(duì)象 : DataSet 是 的核心 , 是專門用來處理從數(shù)據(jù)存儲(chǔ)中讀出的數(shù)據(jù) , 并以離線方式存在于本地內(nèi)存中。 if((,)){(coverLayer)。} The information inquiry of the map datas:The inquiry of datais was mainly carried out by the click of mouse and the choose of frame on the flash which is loaded with the line,the point and the side of layer .We can see whether the field of the mouse choosing contain the object data through querying the courrent layer of the picture ,if exiting,to return the inquiry result in the new Form simplyand show it to the user. The code of the script of mouse option: Function select ( ) { var selectedRegion: Array。 stageWidth=width。t join that Web application program requires, thus when visiting the database of SQL SERVER, superior performance has gotten extensive application. This paper discusses for this. major object of . Many objects in is similar to the object function in ADO , but the function of the object in is more powerful. At the same time, except the objects of the Connection, Parameter and Command , ADO. NET also add a lot of new object and program melt interface, such as DataSet, DataView, DataAdapter, DataReader and DataSetCommand etc..It make more simple to operate the database. DataSet object: DataSet is the core of , is specially used to handle the data which is read out from the stock , and keep it in local memory as away from line. We can use identical way to operate the data which is got from the different data source, the behavior of DataSet is consistent whatever the base layer database is SQL Server or Oracle. In DataSet, it can contain arbitrary quantity of DataTable, and every DataTable is in correspondence with Table or View in darabase. Generally speaking,a corresponding DataTable is a set of a group of DataRow and DataColumn for the data sheet of can take the responsibility for defending each data trip to retain it39。 (Map_mc,200)。 for(i=0。本文對(duì)此進(jìn)行了討論。 的離線連接模式減少了對(duì)數(shù)據(jù)服務(wù)器的壓力。這種方式,可以將兩個(gè)以上的控制項(xiàng)綁定到同一個(gè)數(shù)據(jù)表 , 但顯示的是不同的數(shù)據(jù)。 [ 關(guān)鍵字 ] 獨(dú)立訪問 XML 據(jù)其定義的函數(shù)繪制地圖底層圖形、添加新圖層 , 設(shè)置圖層的可見性等等 : //構(gòu)造函數(shù) function FlashMap (width:Number, height:Number,Geo_x:Number, Geo_y:Number) { layersCount = 0。 } //創(chuàng)建實(shí)例 Map = new FlashMap (stagewidth, stagehight, Mapx, Mapy) 。 for (i=0。 英文二原文 The Data Binding Technology In my project,I need to show the data from the DataBase,so I need to use the data binding technology which Microsoft pany the following ,let39。s page to simplify castin
