Use DW to write a directory tree with ASP + ACCESS

Use ACCESS to create a database listBase. mdb:
Data table: listTable
Data Field: listId listName listInfo parentId connection method:
<%
Dim sConn, sConnStr, sSql
SConnStr = "DRIVER = {Microsoft Access Driver (*. mdb)}; dbq =" & server. mappath ("listBase. mdb ")
Set sConn = server. createobject ("adodb. connection ")
SConn. open sConnStr
%>
Save the above code as a file: initialize. asp the following program code is used to display the directory tree and save it as a file: inc. asp

<! -- # Include file = "initialize. asp" -->
<Script language = jscript>
<! --
// This function is used to display and close its sub-menu, and switch the small image above it
Function showMenu (menuObj, isSub ){
If (menuObj. style. display = "none "){
MenuObj. style. display = "";
If (isSub = 1 ){
Event. srcElement. src = "images/open.gif ";
}
}
Else {
MenuObj. style. display = "none ";
If (isSub = 1 ){
Event. srcElement. src = "images/close.gif ";
}
}
}
// -->
</Script>
<! -- The following blue area sets the root of the directory tree. The content is not the data in the data, and the data in the database is attached to it. // -->
