求助－多线程的MFC对话框程序溢出了

Question

我用VC6写了一个MFC的远程控制软件，控制端是基于对话框的程序，用CListBox显示和索引所有的被控端IP地址 
进来的每个连接都分配一个通信线程，添加和删除ListBox字串用的DeleteString()和InsterString()。 
当控制端运行一段时间后，对话框的显示就出问题，好像是什么地方溢出了，莫非是显存？弄了很久都没解决，请高人指点。 
如图：

代码老长了～我把与listBox有关的代码贴出来//添加一个IP连接

Answer 2

CListBox还没用过, 一直用CListCtrl建议写个死循环, 频繁插入删除试试
