我是Visual C ++ Windows Forms的初学者，我有一些很大的问题（我几天都找不到解决方案......） 基本上我有基本程序表格在线模板。我添加了一些文本框，标签，按钮和一个类。 Class是一张BattleCard，它可以用于＆＃34;战斗＆＃34;使用它的Defend（）函数并使用文本框Text作为他们的统计数据。问题出现时，我试图使这像回合基础，所以你需要每一轮点击开始按钮...一切都很好，除了事实，一旦我点击按钮，所有计算完成...对象和所有统计数据是删除。这意味着对象将从启动HP等开始，而不是刚刚计算的对象。你是否有任何想法如何解决它或只是使这些对象＆＃34;不可取出＆＃34;？

如何防止它们被删除？我需要把它们放在MyForm.cpp中吗？
