從cgdiobject類派生的類如cfont cbrush，析構時會自動deleteobject。
但是在銷毀物件之前，要先把物件從dc中選出（否則deleteobject會失敗）。 *
位圖資源在釋放的時候必須從選中它的dc中脫離。
%當選單失去焦點和視窗不再關聯或者應用程式結束的時候占用資源必須被釋放。
@dc被釋放前必須和它關聯（選中）的點陣圖取消聯絡
#如果脫字元指定了點陣圖，位圖必須被釋放
&對deleteobject的呼叫不會銷毀常規的stockobject（系統內定資源）

科銳課堂筆記 2017 3 25 資源分配釋放規定
在定義乙個資源變數標識時，應賦予初始表分配失敗的錯誤值 如常見的null 每次向系統申請資源或呼叫功能介面時，判斷其錯誤處理，如結果失敗goto跳轉到函式末尾將對程式當前獲取的所有資源進行統一釋放。函式末尾返回前，有一段 將依次釋放所有已分配或占有的裝置資源，釋放前應先判斷變數是否有效，釋放後標記資...
