中间很多代码都不用看，只是我主要标出来的代码有问题，大家帮我看看。我只是想问，我错在哪里了。。。。

普遍问题了，线程里用了MFC类指针的操作，抛出断言了...
还是用发消息的方式吧:
::SendMessage(m_hWnd, LVM_INSERTITEM, 0, (LPARAM)pItem);

[roline]

说详细点好么？你的意思是发个消息，然后重新写个消息函数来处理么？
还有，如果你说是使用指针出了问题的话，为什么我不要这几行代码，整个程序又没问题了呢？
if(recvBuf[4] == 0x35)
{
CString tmp;//
tmp.Format("%d",i+1);//不加这三条语句，运行时就不出错。
//但是完不成我想要的功能---满足条件就在表后加项。
index = listCtrl.InsertItem(listCtrl.GetItemCount(), tmp);//

你可以跟踪看下InsertItem函数的实现过程，里面有ASSERT断，其实InsertItem函数最终调用的也是::SendMessage(m_hWnd, LVM_INSERTITEM, 0, (LPARAM)pItem);,你填充下结构发送就是了

[roline]

在InsertItem内部确实是执行了的，而且返回值也不见是错的啊，晕了

MFC类不是线程安全的.............
