complier說我data[0]->a_number=5; : 並未將物件參考設定為物件的執行個體

[yag]

我不會.NET，但看起來是你那70個data要gcnew Datalab;才行
用個迴圈把它全部new過一遍試試吧

.NET在國內的教學並不熱門，
這是因為國人常常貼了程式碼卻得不到解答。
事實上.NET是一項工業技術，
在西方先進國家，
這一類技術的學習都是要透過視訊教學才能解答問題的。
要做好.NET的學習，
首先要做好下列的幾項準備工作：
1.買一台DV攝影機來錄影電腦畫面。
如果你的預算不夠，
買一台有錄影功能的數位相機或是智慧手機來錄影都可以。
2.把電腦螢幕解析度調整到800X600或是640X480。
顯示螢幕如果可以字大一點，
比較不容易傷眼，
你就可以學久一點。
有些網站建議自定義Visual C++的字體顏色，
你也可以參考使用這些自定義的顏色組合，
網友推薦的顏色組合通常比較不傷眼。

至於你的問題的解答，有下列幾個方式可以解決：
1.Visual C++是一個工業軟體，
可以到微軟網站問微軟人員請求協助。

2.在FORM程式如果要創建一個class的方法如下：
按下"專案"-->"加入類別"，
點選"C++"，
利用泛型C++類別精靈來完成這項類別的設定。
你將需要填寫一個表單，
要填上你的類別名稱，.h檔名稱，.cpp檔名稱，
基底類別也要填寫。
可以改變存取的方式，
public是公開的類別，
private是私有類別，
依照你的情況來使用。

3.最後，安排你的程式碼，
要注意每一個加入的class都要使用按下"專案"-->"加入類別"，
否則自己打進去的public class Myclass這種打字方式，
系統是不會讀取的，
要按下"專案"-->"加入類別"，
編譯器才會知道你有加入類別。
Visual C++是一套工業軟體，
所以你不按鈕的話，光是打字他是不會跑的。

最後，歡迎網友補充說明其他的注意事項。
