Facebook WinForm API (3)

測試下載圖片 GraphApiAsyncExample();
1. Ref: http://www.digitalcoding.com/Code-Snippets/C-Sharp/C-Code-Snippet-Download-Image-from-URL.html
1.1 下載網頁圖片
2  用Ref1建立 Class DownloadImageClass， 製作DownloadImage類別方法。
3. 修改  GraphApiAsyncExample()
var fb = new FacebookClient(_accessToken);
            try
            {
                dynamic result = fb.Get("/me");
                var name = result.name;
                lnkName.Text = "Hi " + name;
                lnkName.LinkClicked += (o, e) => Process.Start(result.link);
                // available picture types: square (50x50), small (50xvariable height), large (about 200x variable height) (all size in pixels)
                // for more info visit http://developers.facebook.com/docs/reference/api
                picProfilePic.LoadAsync(string.Format("https://graph.facebook.com/{0}/picture?type={1}", result.id, "square"));
// ----------- 建置image 物件
// ----------- 下載網址圖片
// ----------- 另存圖檔 Test1.jpg
                Image im = null;
                im = DownloadImageClass.DownloadImage(string.Format("https://graph.facebook.com/{0}/picture?type={1}", result.id, "square"));
                im.Save("Test1.jpg");
4. 測試OK!

Facebook WinForm API (2)

1. There are three forms in this example:
1.1 Mainform (start program)
1.2 Browser in a form (login)
1.3 WinForm (Employ api communicate with Facebook server)
2. Test FqlAsyncSample() @  WinForm class
There are serveral testing methods in the constructor
            _accessToken = accessToken;
            InitializeComponent();
            GraphApiAsyncExample();
            LegacyRestApiAsyncExample();
            FqlAsyncSample();
            FqlMultiQueryAsyncSample();
            GraphApiBatchRequestAsyncSample();
            GraphApiExample();
3.  FqlAsyncSample();
 private void FqlAsyncSample()
        {
            var fb = new FacebookClient(_accessToken);
// 非同步語法             fb.QueryAsync(query); @ 最後一行，完成後執行此事件
            fb.GetCompleted +=
                (o, e) =>
                {
                    if (e.Error == null)
                    {
                        var result = (IList<object>)e.GetResultData();
                        var count = result.Count;
                        lblTotalFriends.Text = string.Format("You have {0} friend(s).", count);
                        foreach (dynamic friend in result)
                        {
// friend.屬性 由 SELECT 欄位名稱決定
                            textBox1.Text +=   friend.last_name + friend.first_name +  ": Facebook username: " + friend.username + "\n\n";
                        }
   
                    }
                    else
                    {
                        MessageBox.Show(e.Error.Message);
                    }
                };
            // query to get all the friends
            var query = string.Format("SELECT uid,pic_square, name, last_name, first_name  FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1={0})", "me()");
            fb.QueryAsync(query);
        }
4. 圖片 pic_square 為url
friend.pic_square

圖形比對(Image matching)

1. Ref: http://briian.com/?p=7224
TinEye 可以用來作為圖形比對。
2. Ref: http://www.tineye.com/search/209759428e73f8572d44b91b861a40f4df7113b9/

3. 似乎有API可以運用。

ASUS TF101 Wiimote

1. ASUS TF101 安裝 WiimoteController 可以操作(取代Mouse)。 2. 觸控螢幕鍵盤失效，需停止WiimoteController, 觸控鍵盤功能可以恢復。

C# Linq (1)

Silverlight application 看來像要運用WCF連接資料庫，先試一下Linq to SQL
工作環境: Windows 7 (x86), VS2010, SQL 2008 R2
1. VS 2010 伺服器管理，連接資料庫
2. 主控台專案，加入新項目(資料 > Linq To SQL 類別) DataClass1.dbml
3. 拖取資料表(Table)進入DataClass1.dbml
4. 記得全部儲存。
5. 測試程式：
static void Main(string[] args)
{
DataClasses1DataContext db = new DataClasses1DataContext();
var ths = (
from us in db.teacher
select new { us.user, us.Email, us.education }).Take(2);
foreach (var t in ths)
{
Console.WriteLine(t.user +"," + t.Email + "," + t.education);
}

}
6.

Server 2008 x64 OleDB

1. 轉移ASP.NET網頁。
2. 系統Server 2008 x64, w/o Office
3. 網頁讀取 Access Database 錯誤 Microsoft.Jet.OLEDB.4.0 提供者並未登錄於本機電腦上。
4. IIS ASP.NET 啟用32位元應用。

Server 2008 IIS (ASP.NET 4.0 尚未在Web 伺服器上註冊)

1. 安裝Server 2008， ASP.NET 網頁無法啟動。
2. VS 2010 檢查顯示： ASP.NET 4.0 尚未在Web 伺服器上註冊
3. Cmd 模式：切換目錄
C:\>cd \WINDOWS\Microsoft.NET\Framework\v4.0.30319
4.註冊
C:\Windows\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis.exe /i
開始安裝 ASP.NET (4.0.30319)。
...............
完成安裝 ASP.NET (4.0.30319)。
