这一个也不能少.
有这样几个问题：
1 我没有去设置对话框的时间，那么它应该默认为2分钟，可是我的对话框一般只有20-30秒就消失了阿，这个是怎么回事呢？
2 你说的WlxUseCtrlAltDel不能少，是什么意思？应该怎么把他用到处理对话框时间的问题上来。
3 msdn上的例子你一定是研究过的，它没有用到WlxSetTimeout，可是也不会出现我这样的问题，至于是不是两分钟以后会不会消失，我会尝试一下的。我的程序只是在原来的基础上作了很小的改动，怎么也会这样呢？

第一个对话框“click here to begin” 是不会消失的，但是后面的对话框两分钟就会消失的。可能就是你说的问题。我自己再琢磨一下
