[OOAD 學習筆記 ] 基本觀念

1. 工作項目清單 :目的是要能有一個工作範圍的索引　
   清單內容應該包含; 入口, 輸入 輸出, key user, 執行工作項目,　此功能的風險　和備案

2.　備案　以及選用的備案　時程安排
3.　review工作項目,應該就要包含　輸入產出的規格
4.　流程　=>　人　=>　工作項目

 [需求階段]
1. 專案七個階段
(1)　需求階段
(2)　架構設計 : 元件
(3)　細部設計 : 元件設計
(4)　程式實作
(5)　測試階段
(6)  驗收階段 和維護系統


2.  Use Case & Actor

3. B9
不過以上面的狀況來說，訂單的處理會經歷不同的部門，每個部門都只做好自己的部份再將之依流程給下一個部門。因此會指定一個負責人員來控管訂單這個物件，隨時判斷它目前在什麼階段，是否出現什麼差錯而需要額外指派什麼工作好讓它回到正常流程。這樣的角色在專案控制工作項目的進行者稱為PM(Project Manager)，在系統設計裡專門控制功能執行的程式稱為controller。

SD卡 卡榫掉了 完美修復

SD卡用久了，卡榫鬆掉了， 甚至掉了

所以嘗試把以前卡榫的位置給遮住

一開始用膠帶把他黏住 但是久了

讀卡機或相機插卡的地方都會黏黏的

所以換成3秒膠 和白紙是最好的組合


先黏一片在SD卡上 整片都要塗抹3秒膠

黏好再用刀片把兩邊乾掉的膠跟紙把他削掉

只剩下一塊卡榫處的白紙 會比只貼卡榫密合

[English] [讀書會] 2010 11 16 : How to Make Latte Art

http://www.eurocafe.jura.com/recipe_cl_cafe-latte_330x300.jpg

step 1. Pour enough milk for one cup into the steam pitcher.

step 2. Put the steam wand at the bottom of the pitcher. Turn on the steam, and slowly raise the wand until it is near the top of the milk. Lower the pitcher as the milk rises so the steam wand stays 1 cm away from the top of the milk. The milk should not stretch too much nor should there be any big bubbles. This should create a smooth, velvety milk as opposed to the foam that sits atop most espresso drinks.

Step3. Allow the milk to reach 80 ºF (27 ºC). Then place the steam wand on the side of the pitcher, deep into the milk, positioning the pitcher to spin counterclockwise. Keep doing this motion until the milk heats to 150 ºF to 160 ºF (65 ºC - 70 ºC).
 
Step4. Shut the steam and remove the steam wand and thermometer from the milk. Clean the steam wand with a wet cloth.

Step5. Let the milk settle for a few seconds. This will allow a more velvety texture.

Step6. Swirl the milk vigorously. If you see any bubbles, pound the pitcher on the counter several times and go back to swirling the milk for 20 to 30 seconds.

Step 7. Start pouring the milk into the espresso.

Step 8. Continue until the foam reaches the top of the cup. Then, sweep the rest of the milk up the center of the newly created pattern. Use a minimal amount to avoid sinking the pattern.

Step 9. Embellish the design using stencils, powder, and milk foam. This step is optional, as many prefer to limit their latte art to "free form" methods, but you may want to experiment with the possibilities added by "etching."

• To write a word, such as "love" in the picture, melt milk chocolate and using a pin as a paintbrush drag the melting chocolate over the foamed milk. More commonly this is done by dipping said pointy object into the cream of the drink being decorated, and then transferring that cream stained foam to the pure white foam to 'draw' a design.

[Silverlight] MultiRow Edit Using One Save Button

為了要一次在一個頁面變更資訊後~
使用者按下Save才將所有變更的內容 透過web service  送出
目前是參考下面兩者的範例 稍微改寫來使用 有點不好XDD
不過時間緊迫 可以先用一下~
可是連結的範例是不錯的~~


1. 在一個頁面 編輯多行欄位 : 以編輯純文字
http://www.scottlogic.co.uk/blog/colin/2010/03/binding-a-silverlight-3-datagrid-to-dynamic-data-via-idictionary-updated/

此範例證實多行編輯文字資料 可以一次送出

稍微修改為

private void Button_Click(object sender, RoutedEventArgs e)
{

             var data = (ICollection<MEpartOverview>)dtgMEParts.ItemsSource;
            foreach(var obj in data)
            {
                  //取得每一行變更的內容
            }
}

2.  在cell中插入 combobox為 欄位值: 用下拉選單來選擇答案

http://www.astaticstate.com/2010/04/binding-combobox-and-autocomplete.html

下面這個範例可以動態連結webservice的內容 來當selection的選項

3. 在cell中插入 Checkbox為欄位值:

http://stackoverflow.com/questions/870163/wpf-simple-checkbox-binding-question

<sdk:DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
         <StackPanel>
          <CheckBox Margin="10" x:Name="cbxMEDel" Tag="{Binding mark}" IsChecked="{Binding mark}">DELETE</CheckBox>
           </StackPanel>
          </DataTemplate>
  </sdk:DataGridTemplateColumn.CellTemplate>
