對於PC版大尺吋的螢幕,當網站要 feed 資料到 facebook 時,可以使用 javascript SDK 的
FB.ui => method:'feed' 方式處理,參考位置。此方法會popup小視窗讓user可以分享資料出去。
但是遇到手機版網頁就有點麻煩,實測上手機版的 chrome 會出現轉不停的情況,無法分享;而iPhone則是另開新頁面處理,可以成功但是會多一個分頁。所以手機版網頁建議使用 redirect 方式處理分享機制,參考位置
var fbUrl = "https://www.facebook.com/dialog/feed?" +
"app_id=122465741241119&display=touch" +
"&link=" + encodeURIComponent("http://www.shopunt.com/tch/FixPage.aspx?id=525") +
"&picture=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/fb_200x200.jpg") +
"&description=" + encodeURIComponent("市價不斐的光療DIY教學,UNT傾囊相授!10場巡迴免費教學,讓妳輕鬆掌握光療DIY訣竅,並搶先體驗秋冬最新流行色!現場打卡,再送時尚美甲工具組") +
"&redirect_uri=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/Handler.ashx?fun=FBCallback");
當然以 redirect 處理與 javascript 方式處理是兩種不同的方式,redirect 方式的 callback 網址 (redirect_uri)要接收facebook 導回的 post_id , javascript 方式則是 callback function 處理 post_id

網站開發,善用 Cached DataTable 可以使網站效能倍增,不必一直去資料庫抓資料。
但是使用 Cached DataTable 有一個地方要注意
就是他是 Shared 物件,表示同時有好幾個頁面都可以存取他
例如A網頁將資料抓出,然後變更裡面的DataRow資料,
另一個B網頁也會跟著變更
由於 Cached DataTable 在 Set DataRow Value 時
可能 Critical Section 沒有處理好,若真的同時多個thread 操作
會出現 Exception
(System.ArgumentOutOfRangeException: 索引超出範圍。必須為非負數且小於集合的大小。)
建議:
'這是 UNT FixPage 物件抓取單一資料的範例
Shared Function GetSpecialPage2FromCachedDT(ByVal Key As Int32) As DB.SpecialPage2
Dim DT As DataTable = GetAllDataFromBaseTableWithCache()
Dim Row As DataRow = DT.Rows.Find(Key)
If Row IsNot Nothing Then
'避免每個thread都共用table 寫入資料會出現問題
Dim newDT As DataTable = DT.Clone()
newDT.ImportRow(Row)
Return New SpecialPage2(newDT.Rows(0))
Else
Return Nothing
End If
End Function
'載入物件,bin/ 要放入 .dll
