呢個問題足足搞左我一晚, 都唔差左用多少少時間打篇BLOG 做過紀錄

事緣有個舊WEB 不嬲都用開BIG-5, 又咁岩用Jquery ajax submit d data 返server side, 大家都知jquery ajax 會變曬你d 野做utf8 先傳回server, 所以唔做野一定出亂碼

<meta http-equiv=\"Content-Type\" content=\"text/html; charset=big5\" />

shopname = encodeURI(shopname);

<?php
$shopname =  iconv(\"utf-8\",\"big5\",addslashes(urldecode($shopname)));
?>

urldecode() 之後再用 iconv 由utf8 轉返做 big-5 再INSERT 入mysql

就係以上呢幾行CODE 又無左一晚 T_T

This little box has, inside it, some kind of circuitry that harvests WiFi energy out of the air and converts it into electricity. This has been done before, but the Airnergy is able to harvest electricity with a high enough efficiency to make it practically useful: on the CES floor, they were able to charge a BlackBerry from 30% to full in about 90 minutes, using nothing but ambient WiFi signals as a power source.

呢隻CHARGER 可以利用大氣中既wifi signal 轉化做電能為你既usb device 充電, 當然充電時間會好長 , 90 分鐘可以充到一部BlackBerry 既30% 電, 都幾搞野下

個人覺得實用性就唔高喇, 不過作為一件環保產品就十分有諗頭, 價錢亦都唔貴, 只係USD40, 有興起可以買返一舊黎型下比D friend睇

Facebook 呢個全球最大用緊PHP 既網站, 終於都訂唔住php 既速度, 索性自己寫過另一個ENGINE, 不過有趣之處在於, 佢係先張PHP->C++ 之後再complie , C++ 既performance 我諗大家唔使有任何擔心喇掛

之前set 左好耐都set 唔到, m$ d offical document 又成日張sql2000 同sql2005 一齊講, 講都唔清唔楚, 足足搞左我好多日. 最後發現原來係白痴問題一個. 以下有小小心得, 大家有興起用可以參考一下

1. 首先  web.config 並不需要任何設定  , 因為它是針對SQL2000 polling base 而設的
2. 在SSMS 執行指令
“alter database testdb set enable_broker  WITH ROLLBACK IMMEDIATE”

3. 在Global.asax application_start() 加入
System.Data.SqlClient.SqlDependency.Start(“your connection string here”);

4. 以下係小弟既測試function

[cc lang='csharp' ]

// Create the ADO.NET objects.
string connectionString = Common.DB_ConnString;
string query = “SELECT [ParmKey],[ParmValue] FROM dbo.[ParmTable] where [ParmKey] = ‘test’”;
SqlConnection conn = new SqlConnection(connectionString);
SqlCommand command = new SqlCommand(query, conn);
SqlCacheDependency dependency = new SqlCacheDependency(command);
SqlDataAdapter adapter = new SqlDataAdapter(command);
DataTable dt = new DataTable();
adapter.Fill(dt);
Cache DataCache = HttpRuntime.Cache;
DataCache.Insert(“ParmTableDT”, dt, dependency, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration);

[/cc]

我一直既失敗原因為係為我個 SqlCommand 個object 入去init SqlCacheDependency 既時候未沒有被執行過 (即係adapter.fill(dt)) , (因為我之前寫落左d help class 用黎行sql statement, 所以唔係用SqlDataAdapter ), 所以就算intial 左果 SqlCacheDependency, 佢都認唔到你句sql statement, 亦都因為咁所以個cache 永遠都唔識expired….

就 係呢樣咁簡單既野搞左我幾日…真係唔抵
