請問前輩們，該如何繼承一個 Form 呢？ 小弟想達到繼承後能保有舊 Form 中的元件 我想繼承後元件的 Name 應該也跟舊 Form 一樣才對？ 可以的話是否能補充關於繼承這方面的概念 繼承後的 Form 與元件跟舊 Form 會不會有什麼不同 是否有什麼該注意的地方 小弟對繼承的 code 並不了解 希望前輩們指導。

流您好:    以下簡單的範例您參考看看!

HAVE A NICE DAY FOR YOU 發表人 - axsoft 於 2003/08/04 14:18:55

Visual form inheritance? I don't have BCB, but it should be similar: 1) create a new project (e.g. Demo) 2) create your base form (Form1) 3) IDE menu, File|New|Other, select the tab with your project's name (e.g. Demo). Select your base form and OK... 4) a new form inherited from Form1 is created...

謝謝 axsoft 的指導 其實我發現有蠻多地方語法都不懂 我有必要好好的找 c 的研究 感謝!
