我用一个线程来获取一个随机数然后把随机数的值添加到label上，可是当我运行这个程序时，这个程序不用多少时间就会没有响应了，这是为什么啊？难道是我的程序上的问题？

不会吧,可能是你代码上的错误哦.

我把代码贴出来 大家看看哪里有错误！

自己调试一下不就清楚了

因為你在用其他線程操作ui

我把跨线程使用控件的属性值该了，可以按照03的使用。
但是

我试过了，在2005上面启动一geThread，可以看到随即变幻的数据，但是启动两个以后就死了。。

从program上面看，似乎每个随机数都是一个单独的thread控制，为什么会死掉呢？

用委托 就OK了

可以解释一下为什么界面会死吗？

照理说每个随机数新开一个thread 不会影响主线程的运转吧。。。。。。。。。。。

我一直是这么理解的。。。。。。

不对吗？

看下cpu是不是100%?

能说得明白一些吗？该怎么改啊？？
