I have an asp page called protected.asp which is accessed after users login. I would like users to be able to click a button and view the contents of a folder (called "uploads") and download the files (mainly pdf's)they wish to view. How do I do this? All help is appreciated!!! Please go easy, I am an ASP newbie.

The next step to this would be to allow users to upload files with a filename and description for users to view.

Thanks!!!!!

Take a look at W3Schools tutorials about FSO (File System Object), it's everything you need.

Here's what I came up with but when I click on the link to the file in the table, it says page not found. Any ideas?!


<<%@ Page Language="VB" %>
<%@ Import Namespace="System.IO" %>
<script language="VB" runat="server">

Sub Page_Load(sender as Object, e as EventArgs)
Dim strPath As String = "./uploads/"
Dim myDirInfo As DirectoryInfo

lblPath.Text = strPath

myDirInfo = New DirectoryInfo(Server.MapPath(strPath))

dgFileList.DataSource = myDirInfo.GetFiles()
dgFileList.DataBind()
End Sub

</script>


<html>
<head>
<title>ASP.NET Directory List Sample</title>
</head>
<body>

<p>
Contents of <strong><asp:Literal id="lblPath" runat="server" /></strong>
</p>

<asp:DataGrid id="dgFileList" runat="server"

Border = 5
BorderColor = "green"
CellSpacing = 0
CellPadding = 2
HeaderStyle-BackColor = "#006600"
HeaderStyle-ForeColor = "#FFFFFF"
HeaderStyle-Font-Bold = "True"
ItemStyle-BackColor = "#CCFFCC"

AutoGenerateColumns="False"
>

<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="Name" DataNavigateUrlFormatString="dir/{0}" DataTextField="Name" HeaderText="File Name:" />
<asp:BoundColumn DataField="Length" HeaderText="File Size (bytes):" ItemStyle-HorizontalAlign="Right" />
<asp:BoundColumn DataField="LastWriteTime" HeaderText="Date Created:" />
<asp:BoundColumn DataField="Extension" HeaderText="File Type:" />
</Columns>
</asp:DataGrid>

Oh, sorry, when you told only ASP, I thought that you was telling about ASP3...

Can you show the HTML output generated when the is ran?

The page cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Please try the following:

If you typed the page address in the Address bar, make sure that it is spelled correctly.

Open the home page, and then look for links to the information you want.

Before clicking on the link, right click on the page and open the HTML source code, and post it here.

before clicking on the link to open the file or to open the aspx page itself?

This is the source code using the method you described of the aspx page itself which displays the contents of the directory and allows users to click on the file.

there is no web.config file on the web server at all .. .. what do I do next? This is puzzling since I have asp pages that are working fine on the site.

For the record, even if there was a web.config file, IIS wouldn't let you have access to it, or request it from a browser.

Split the following line into two lines:
Code: 
myDirInfo = New DirectoryInfo(Server.MapPath(strPath))
and slap a breakpoint on it. Basically assign the returned value from Server.MapPath to a variable then use that variable for your DirectoryInfo object. This way you can see what path it builds before it continues.

The "dir" addition is coming from the property here:
Code: 
DataNavigateUrlFormatString="dir/{0}"

i'm fairly certain that needs to be corrected if I have read your intentions and posts correctly.

Code: 
Dim strCompletePath As String
strCompletePath = Server.MapPath(strPath)
myDirInfo = New DirectoryInfo(strCompletePath)

Or just...

Code: 
strPath = Server.MapPath(strPath)
myDirInfo = New DirectoryInfo(strPath)

Any ideas? The goal here is to display the list of files in a directory, which it does. And then allow users to click on a file and download it which is where it displays page cannot be displayed once the file is clicked on.
