Symbian一个活动对象的测试例子

核心提示：今天闲来无事写了一个活动对象的测试代码,谁知道一运行死活跑不起来.程序执行到SetActive()就自动退出.硬是把这个简单的例子搞了2个小时. 后来才知道原来Carbide.vs提供的Active框架没有重写NewL()或者NewLC()方法,而我直接调用new (ELeave) CActiveTest2NewCla

今天闲来无事写了一个活动对象的测试代码,谁知道一运行死活跑不起来.程序执行到SetActive()就自动退出.硬是把这个简单的例子搞了2个小时. 后来才知道原来Carbide.vs提供的Active框架没有重写NewL()或者NewLC()方法,而我直接调用new (ELeave) CActiveTest2NewClass;并没有初始化ConstructL()里面的数据.编译也不报错,Debug跟踪却是下面一行出问题.郁闷的要命.

下面的代码就是今天的收获:
