UseSubmitBehaviot 屬性是控制Button於HTML輸出時Type是否為submit或Button屬性
在ASP.NET的Button控制項中預設是會去執行postback，也就是會在submit時會自動去執行__doPostBack 函式
而如果在Button設定UseSubmitBehaviot=false時，Button必須在onClick事件中自行去呼叫__doPostBack 函式
 

一.由IIS產生Session並給予一組24字元的SessionID
二.在需要回傳資料給伺服器時由瀏覽器將SessionID附加在HTTP訊息標頭中傳回給IIS做為身份辨識,伺服器處理完資料後依照SessionID回傳給個別的Client端
三.Session在Web.config的常用設定
1.在<System.Web>標籤內
< sessionState
mode="Off|InProc|StateServer|SQLServer"
cookieless="true|false"
timeout="number of minutes"
stateConnectionString="tcpip=server:port"
stateNetworkTimeout="number of seconds" 
sqlConnectionString="sql connection string"
sqlCommandTimeout ="number of seconds"
/>
ex.

    using System.Runtime.InteropServices; //使用DllImport public partial class Form1 : Form{ [DllImport("kernel32.dll")] static extern void GetSystemTime(out SYSTEMTIME lpSystemTime); private struct SYSTEMTIME { public ushort wYear; public ushort wMonth; public ushort wDayOfWeek; public ushort wDay; public ushort wHour; public ushort wMinute; public ushort wSecond; public ushort wMilliseconds; } private void GetTime() { // Call the native GetSystemTime method // with the defined structure. SYSTEMTIME stime = new SYSTEMTIME(); GetSystemTime(out stime); // Show the current time. MessageBox.Show("Current Time: " + stime.wHour.ToString() + ":" + stime.wMinute.ToString()); }}
