fso help

[Rob Lavin]

Hello. I am trying ot make a menu for a web page that is built from the folder structure on the server. I have go the basics working, but have 2 questions.

1) Can this code be cleaned up?

<%
  for each FolderIndex in MSubfolders
  'create menu items for all folders that do not start with an underscore
    if Left(FolderIndex.name,1) <> "_" Then
      response.write ("<li><a class='qmparent' href=" & (HOME) & "?loc=/intranet/" & Replace ((FolderIndex.name)," ","%20") & "/>" & (FolderIndex.name) & "</a>")
        MSubpath = Server.MapPath(FolderIndex.name)
        MSubfolder = FSO.GetFolder(MSubpath)
        MSubfolders = MSubfolder.SubFolders
        if (MSubfolders.count > 1) then
          response.write("<ul>")
          for each MSubfolderIndex in MSubfolders
            if Left(MSubfolderIndex.name,1) <>"_" Then
            response.write("<li><a href=" & (HOME) & "?loc=/intranet/" & Replace((FolderIndex.name)," ","%20") & "/" & Replace(Replace(MSubfolderIndex.name," ","%20"),"&","&amp;") & "/>" & (MSubfolderIndex.name) & "</a></li>")
          End If
          next
          response.write("</ul>")
        End If
        MSubfolders = nothing
        response.write ("</li>")
      End If
      next
    MSubolders = nothing
%>

Within the current folder, I need to build a list of folders, files, subfolders, subfolder files, and check if the subfolders contain more subfolders or if they are the last level. Can this be done directly with FSO or do I need to keep repathing a variable (like MSubFolders above)?

2) is there a way to handle '&' in the folder name? I tried

Replace(Replace((FolderIndex.name)," ","%20"),"&","&")

to replace both ampersands and blank spaces, but it wouldn't work. Any ides?

Thanks for looking this over!

Hi Rob,

Welcome to Bytes.com. Please be sure to take a read through the Posting Guidelines and FAQs.

I've edited your posts to include use of our code tags - you can use these yourself, when posting a message, you'll see the # sign on your toolbar.

With regards to your question, the answer is normally a recursive function - one that calls itself iteratively until a certain condition is met (in this instance, there are no more subfolders). When I was doing classic ASP, recursion had me completely lost unfortuantely, so I'll leave it to another expert to help you out.

This is how I would do it.. Feel free to ask questions about any of it you don't quite understand

<%
Dim Home
Home="www.somewhere.com"
set fs=Server.CreateObject("Scripting.FileSystemObject")
set MainFolder=fs.GetFolder(Server.MapPath("/"))
set MSubfolders=MainFolder.SubFolders
pWrite("<UL>") 'add crlf to make it pretty
for each FolderIndex in MSubfolders 
	if Left(FolderIndex.name,1) <> "_" Then 'create menu items for all folders that do not start with an underscore 
		if Not FolderIndex.Attributes AND 2 then 'if its not a hidden folder
			call makeMenu(HOME, FolderIndex.name, "qmparent")
			call getSubFolders(FolderIndex)
		end if
	end if
next 
pWrite("</UL>")
set MSubolders = nothing 


'recursion ;)
public function getSubFolders(current_folder)
	set MSubfolders = current_folder.SubFolders 
	pWrite("<UL>")			
	for each FolderIndex in MSubfolders 
		if Not FolderIndex.Attributes AND 2 then 'if its not a hidden folder
			call makeMenu(HOME, FolderIndex.name, "qmchild")	
			call getSubFolders(FolderIndex) 'call itself to get all this folders sub folders. and so on till the end recursion()
		 end if
	next	
	pWrite("</UL>")			
end function
	
public function pWrite(str)
	response.write str & vbcrlf
end function	
	
'generalized function
public function makeMenu(Home, Link, className)
		pWrite("<LI>")
		pWrite("<a class=""" & className & """ href=""" & HOME & "?loc=/intranet/" & server.URLEncode((Link)) & """/>" & Link & "</a>") 
		pWrite("</LI>")
end function
%>

If you want the full path you can use something like this

<%
Dim Home
Dim strTopath
Home="http://www.somewhere.com"
set fs=Server.CreateObject("Scripting.FileSystemObject")
set MainFolder=fs.GetFolder(Server.MapPath("/"))
set MSubfolders=MainFolder.SubFolders
pWrite("<UL>") 'add crlf to make it pretty
for each FolderIndex in MSubfolders 
	if Left(FolderIndex.name,1) <> "_" Then 'create menu items for all folders that do not start with an underscore 
		if Not FolderIndex.Attributes AND 2 then 'if its not a hidden folder
			call makeMenu(HOME, fs.GetParentFolderName(FolderIndex) & "\" & FolderIndex.name, "qmparent", false)
			call getSubFolders(FolderIndex)
		end if
	end if
next 
pWrite("</UL>")
set MSubolders = nothing 


'recursion ;)
public function getSubFolders(current_folder)
	set MSubfolders = current_folder.SubFolders 
	pWrite("<UL>")		
	for each FolderIndex in MSubfolders 
		if Not FolderIndex.Attributes AND 2 then 'if its not a hidden folder
				call makeMenu(HOME, fs.GetParentFolderName(FolderIndex) & "\" & FolderIndex.name, "qmchild", false)	
				call getSubFolders(FolderIndex)
		 end if
	next	
	pWrite("</UL>")
end function
	
public function pWrite(str)
	response.write str & vbcrlf
end function	
	
'generalized function
public function makeMenu(Home, Link, className, showFullLogical)
		if not showFullLogical then
			link=replace(link, Request.ServerVariables("APPL_PHYSICAL_PATH"), "")
		end if
		pWrite("<LI>")
		pWrite("<a class=""" & className & """ href=""" & HOME & "/" & server.URLEncode((Link)) & """/>" & Link & "</a>") 
		pWrite("</LI>")
end function
%>
