这个可以，但有一个缺点，刷新后有的节点是打开的，谁能看看是怎么回师
Access数据库
● 数据库名：tree
● 表名：tree
● 字段名的设计
ID 文本类型编码
Name 文本类型节点文字
HyperLink 文本类型相关信息

id name belong_id(上级id) index_id(顶级id)
这样的表结构递归时的recordset对象怎么处理
sub tree()
sql ="....."
rs.open sql,conn,1,1
while not rs.eof
'''''''
call tree()
wend
''''
end sub
程序大概就是这个样子，循环时rs不能close怎么办
