02 VSE開發環境介紹

2.1 建立新網站
選擇 ASP.NET空網站
使用VB語言
系統自動產生Web.config
在方案總管新增Web Form (.aspx)
 - code behind model or inline code separation model
於Web Form的div輸入文字

2.2 VSE整合開發環境介紹
各窗格簡介
2.2.3 工具箱
Server Controls
 - 標準控制項、資料控制項、驗證控制項、巡覽控制項、登入控制項、AJAX擴充功能控制項、HTML控制項

＃VSE設定匯出：工具——設定——匯入與匯出設定

2.3 建立與操作Web Form的控制項
<%@Page Language="VB" %>
 - @Page指示詞
runat="server"
 - 由伺服器進行編譯與執行
2.3.1 建立控制項
於form中加入標籤控制項
2.3.2 絕對定位
點選div
拖曳div範圍，使之變大
新增標籤控制項
點選標籤控制項
執行『格式&位置』
按下『絕對定位』
即可將標籤拖曳至任意位置
＊這是利用CSS語法來設定控制項位置

＃程式碼顏色：綠色為修改並儲存，黃色為修改未儲存
