Automatically open a local file from a web page

Hi all,

I would like to design a web service ( or a script embedded into a web page running on a local host) which accepts fileid as a parameter and then automatically open corresponding file in the same host.

for example if we enter http://localhost/openFile.aspx?id="JohnBrown" to browser on a windows PC, it should automatically open file JohnBrown.ppsx stored in the hard drive.

Could you guide me how to achieve this?

Thanks

Create the following pages to open file -

Page One = page with link to page two

<%@LANGUAGE="VBSCRIPT"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>

<body>
<a href="download_go.asp">Download File</a>
</body>
</html>

Page Two = page with code to get file

<%@LANGUAGE="VBSCRIPT"%>
<%
Dim objStream, myContents, myFileName

myFileName = "<Get the filename from querystring & add file extension>"

Response.ContentType = "application/octet-stream"
Response.AddHeader "content-disposition", "attachment; filename=" & myFileName

Set objStream = Server.CreateObject("ADODB.Stream")

objStream.Open
objStream.LoadFromFile Server.MapPath(myFileName)
myContents = objStream.ReadText

Response.BinaryWrite myContents

objStream.Close
Set objStream = Nothing
%>

Which hard drive? The server hard drive or the client hard drive?

WCF is Web Services. They are not two separate things.
Use WCF for All New Web Service Development, instead of legacy ASMX or obsolete WSE

Hello,

Please clarify that where the file is located on server or client machine? I dont think there is some way by which we can open a file located on client machine.

This is against Security best practices and I am sure no browser will allow you to open a local file unless until security is negotiated.

You have three options.

Option One

Use Active X and prompt user to download and install your active X and from Active X you can open a file.

Option Two

HTML 5 allows you to do this task up to some extent.

Option Three

Ask user to upload the file to server and using a powerpoint viwer control from serverside you can show the requered ppt

Your question has nothing to do with asmx web service and we have a more dedicated forum for asp.net @ http://forums.asp.net/ where some expert can give you prompt answer.

We have our NFC tag reader application which only opens valid http urls. So we want to redirect request through a web page running on local host. So when we embed URL http://localhost/openFile.aspx?id="JohnBrown" to NFC tag, the reader will open this URL but we want to design openFile.aspx file in a way that it will take id "JohnBrown" and then open a local file defined by URL "file:///C:/JohnBrown.ppsx"
