这段递归展开树的程序有什么问题吗?
当多子项目多的时候,就死机.

HTREEITEM hSubItem ;
if(hItem != NULL)
{
//CString sItem = this->GetItemText(hItem);
TRACE("expand %s \n", sItem);
Expand(hItem,TVE_EXPAND );
hSubItem = GetChildItem(hItem);
}
else
{
return;
}
if(hSubItem!=NULL)
{
expandAllItem(hSubItem);
}

HTREEITEM hSiblingItem = GetNextSiblingItem(hItem);
while((hSiblingItem != NULL)&& (bWithFirstLevel))
{
expandAllItem(hSiblingItem);
hSiblingItem = GetNextSiblingItem(hSiblingItem);
}

输入不全,重发
void CMYTreeCtrl::expandAllItem(HTREEITEM hItem,BOOL bWithFirstLevel)
{

HTREEITEM hSubItem ;
if(hItem != NULL)
{
CString sItem = this->GetItemText(hItem);
TRACE("expand %s \n", sItem);
Expand(hItem,TVE_EXPAND );
hSubItem = GetChildItem(hItem);
}
else
{
return;
}
if(hSubItem!=NULL)
{
expandAllItem(hSubItem);
}

HTREEITEM hSiblingItem = GetNextSiblingItem(hItem);
while((hSiblingItem != NULL)&& (bWithFirstLevel))
{
expandAllItem(hSiblingItem);
hSiblingItem = GetNextSiblingItem(hSiblingItem);
}

}

急

expandAllItem(HTREEITEM hItem,BOOL bWithFirstLevel)
你在用这个函数时,只有一个参数,为什么定义时写两个参数呢?

理论上没有什么问题了.
