Access to Shared folder from asp.net

[Guest]

Hello,

How can I access a Shared Folder of the Server by using the following control.

1. I need to download files from c:\resumes folde by using the following;

<asp:HyperLink
NavigateUrl='<%#DataBinder.Eval(Container.DataItem,"FilePath") %>'

a. FilePath is a database field holding the value "c:\resumes\myresume.doc"

b. NavigateUrl will prefix the virtual path & then the filepath.

Any thoughts are welcome

I'm doing something similar on a web application. For various reasons, I
pulled a copy of the document (a PDF) into a temporary directory under the
website that I associated with a particular user. When the user's session
expires (or when they log off), I clear their cache. For my requirements and
my application, this was the best choice.
You might want to look at streaming the document directly into a webpage
rather than allowing anonymous users access to the resume directory. Giving
anon users access to a shared folder is a security problem. At least make
sure the user account under which access will be granted (aspnet or whatever
in your case) has read-only access...

Instead of using a Hyperlink that directly links to the shared folder, use a
button (or a buttoncolumn in a datagrid). On the server side while processing
the click event of that button you can have the asp.net account read the
resume and write to the web page, e.g.

Response.Clear();
Response.ContentType = "application/vnd.ms-word";
HttpContext.Current.Response.AddHeader("content-disposition",
"attachment;filename=test.doc");
Response.WriteFile (@"c:\Resumes\myresume.doc");

Hi,

Thanks a lot for your reply.

Yes, your solutions works fine, but going futher How can I dynamically send
the full file name(with the path) to the click event of LinkButton.

My case is that the file names are programatically read from the repository
& binded to the Linkbutton, so upon the click event the associated files
names are downloaded..isnt?

Thanks,

Hi Ibrahim,

The LinkButton allows you to use a CommandArgument, e.g.

<ItemTemplate>
<asp:LinkButton Runat="server" ID="lnkResume"
CommandArgument ='<%#DataBinder.Eval(Container.DataItem,"FilePath"")%>'
CommandName ="Navigate"
Text='<%#DataBinder.Eval(Container.DataItem,"UserName","Resume for
{0}")%>'>
</asp:LinkButton>
</ItemTemplate>

Then while handling the ItemCommand event of the DataGrid (or the RowCommand
of the GridView) you would get the CommandArgument like this:

private void datagrid1_ItemCommand(object source, DataGridCommandEventArgs e)
{
string strLink = e.CommandArgument.ToString ();
// if strLink has only the file name without the path
// then uncomment the following line
// strLink = Server.MapPath (strLink);
Response.Clear();
Response.ContentType = "application/vnd.ms-word";
HttpContext.Current.Response.AddHeader("content-disposition",
"attachment;filename=Resume.doc");
Response.WriteFile (strLink);
}

hi,

I'm using the following code for the LINKbutton, but get file damaged error
at the client side; do i have to use proper encoding?, the file opens
correctly when i access it directly.

Dim myFileInfo As New FileInfo(sender.CommandArgument)
Dim myFilePath As String =
System.Configuration.ConfigurationManager.AppSettings("UploadFolder").ToString & "\" & myFileInfo.Name
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.ClearHeaders()
HttpContext.Current.Response.ClearContent()

Response.ContentType = "application/pdf"
HttpContext.Current.Response.AppendHeader("content-disposition",
"attachment;filename=" & myFileInfo.Name)
Response.WriteFile(myFilePath)
Response.End()

Regards,
