Dear Experts,

In my web application, I am having a button to open a file located in the
server. When I click on the button to view the file, I received the following
error message:
----------------------------------------------------------
Exception from HRESULT: 0xC004800A
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information about
the error and where it originated in the code.

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET
Version:2.0.50727.42
-----------------------------------------------------------------

The webserver is running on Windows 2000 sp4 and with .NET Framework 1.1,
1.1 sp1 and 2.0 being installed. This server is also running as Active
Directory. I have manually created a user named ASPNET and assigned full
control to the folder that contains my files.

May I know what is the possible solution to this problem? Please advise.
Thanks.

One possibility is absolute paths are disabled in IIS.

Ask your web provider to go into IIS and enable this for you. Or code around
it. Go to IIS properties for the site and go to Home Directory. Click
"Configuration" and then "Options" and check "Absoulte paths" allowed.

Or better yet host with me and not have this issue.

(Just kidding.) :)

These are not vb.net solutions. But they do work.

<%
Response.Buffer = True
Const adTypeBinary = 1
Const adReadAll = -1

Dim oStream
set oStream = server.CreateObject("ADODB.Stream")
oStream.Type = 2
oStream.Charset = "ascii"
oStream.Open "URL=http://testserver/test/hello.htm", 1, -1

'Response.write oStream.State
'Response.End
'oStream.Read

'Response.Write oStream.Size
'Response.End

oStream.Position = 0
Response.ContentType = "text/html"
Response.Write oStream.ReadText
oStream.close

%>

oR

<%
Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP")
url="http://www.myserver.com/textFile.txt"
xml.Open "GET", url, true ' the True specifies an asynchronous request
Call xml.Send()
Response.write xml.Responsetext
