【正文】 order with the form of form that what data acquiesce in look over way, and the order of data that put data in order follow the order taking out the trip that put litre and the fence position of row order in order from database data sheet, usually it is concerned with the Sort Order or reduce power in inquiring string when design the database .ADO. NET offer the way that has elasticity very much to let user use row order and condition filter , seek etc. property way of looking over of defining difference , so, edit and glance over data or show the data in DataTable .For instance ,we can establish a DataView object, then designate with with default look over ( DefaultView ) different row order way, or also can use condition filter ( Filter ) look over the partial data in data sheet. This kind of way can tie two above control items to a same data sheet, but what show is thay the different data. DataAdapter object: ADO. NET establish and initialize data sheet through DataAdapter, so as to keep the data in the memory bining with DataSet object. DataAdapter object can hide the details that links up with Connection and Command. DataAdapter object allow to put the data to the data source ( DataSource )which gets from DataSet can also take out data from data source. By the same way,it can also operate the bottom data preserved by adding ,deleting or modifing. Database in joining The analysis of a example which visit the database of SQL SERVER in technology [ abstract ] With the thorough that applied along with distributed database, permanent database connection consumes resource fairly. When visiting the database of SQL SERVER, it can solve this problem perfectly with ADO . NET technology . This paper primarily discusses Net the major object of , and analyse the course of visiting SQL SERVER furtherly. [ keyword ] ADO. NET visit XML independently Drawing the bottom graph of the map, add new picture layer according to the fuction of defined , Setting picture layer visibility and so on: / / constructs function function FlashMap ( width: Number, height: Number, Geo_x: Number, Geo_y: Number ) { layersCount = 0。 layers=new Array()。 //Loading map function initMap () { Map. drawMap ()。 i++){var Region:MapRegion=MapRegion( [i])。同時 , 除 Connection、 Parameter、 Command 對象外 還添加了許多新的對象和程序化接口 , 如 DataSet 、 DataView、 DataAdapter、 DataReader、DataSetCommand 等 , 使得對數(shù)據(jù)庫的操作更簡單。例如 , 一個鏈接 (Connection) 用傳統(tǒng)的 ADO Recordset 對象去讀 1000 行數(shù)據(jù)庫的記錄 , 則必須為這 1000 行記錄將內(nèi)存分配給這個鏈接直至這個鏈接的生命周期結(jié)束。 DataAdapter 對象能隱藏和Connection、 Command 對象溝通的細節(jié)。 stageWidth = width。 } 地圖數(shù)據(jù)的信息查詢 : 對于 flash 上加載的地圖各圖層的點、線、面數(shù)據(jù)的查詢主要是鼠標的點選和框選來實現(xiàn)的 , 通過查詢當前圖層中是否有實體對象數(shù)據(jù)包含在鼠標選擇范圍內(nèi) , 若存在則返回簡單查詢結(jié)果在新窗口中顯示給用戶。 i++) { var Region:MapRegion = MapRegion ( ary [i]) 。s DataBind method is called. You can place data binding expressions on the value side of an attribute/value pair in the opening tag of a server control or anywhere in the page. All data binding expressions, regardless of where you place them, must be contained between % and % characters. When used with data controls (like Repeater, DataGrid, and so forth), the expression parameter is usually a column name from the data source. However, as long as it returns a value, any valid expression may be used. Likewise, the same syntax may be used outside list controls. This includes displaying values on the page or populating control attributes. is a runtime alias for the DataItem bound to a specific item. It maps to an individual item from
