資源簡介
1.參照Windows系統提供的計算器功能，制作一個自己的計算器，至少能完成數據的加減乘除的基本功能。
2.控件的焦點以及Tab鍵的設置和使用
3.多個控件（按鈕）事件的共享
4.鍵盤的事件的應用
創建主體框架：主要是對計算器的外觀進行手動的設計，系統自動生成界面的主要窗口生成代碼。對于每個按鈕的的代碼段中，分別添加事件觸發的處理代碼，在label標簽中，顯示輸入的信息和顯示處理后的結果。
其中標簽的上面顯示的是運算式子，下面是當前輸入或者是結果。
數字1-9的按鍵的事件處理都是在label標簽中分別添加相對應的數字字符，把數字當成是字符串處理。對于加減乘除四則運算按鍵，事件觸發后的處理是在l
