Running a process from ASP.NET

I am trying to spawn a seperate process from my asp page
so when a user clicks the link or button a desktop program
is launched. This will be on an intranet and the program
will exist on the users desktop. I can use the following
code in webmatrix to run a process on my local machine:

<%@ Page Language="VB" %>
<script runat="server">

' Insert page code here
'

Sub Button1_Click(sender As Object, e As EventArgs)
Dim startInfo As System.Diagnostics.ProcessStartInfo
startInfo = New
System.Diagnostics.ProcessStartInfo()
Dim p As System.Diagnostics.Process = New
System.Diagnostics.Process()
startInfo.FileName = "c:\8133324.txt"
startInfo.WindowStyle =
System.Diagnostics.ProcessWindowStyle.Normal
p.Start("c:\winnt\notepad.exe")
End Sub

</script>
<html>
<head>
</head>
<body>
<form runat="server">
<asp:Button id="Button1" onclick="Button1_Click"
runat="server" Text="Button"></asp:Button>
&nbsp;<!-- Insert content here -->
</form>
</body>
</html>
But in .NET Studio running on IIS the process doesn't
spawn. I have tried the following code:

Dim startInfo As New ProcessStartInfo("IExplore.exe")
startInfo.WindowStyle = ProcessWindowStyle.Normal
Process.Start(startInfo)

in a button click event, but nothing happens. Any help
would be greatly appreciated.
(Please send VB code, I know C# but this shop uses VB.NET
only)

This is not possible, IIS, ASP.NET and processes spawned by one of both run in a secured desktop/winstation not the desktop of the
currently logged-on user. So you wont see the "Notepad" window pop-up, but notepad should show up under taskmanager.

Do you understand the ASP.NET code is executed on the SERVER?

John,

This sounds like a browser security issue. I'm 99.9% sure that spawning
processes on the local machine, via a web page, is turned off as it is a
"BIG" security issue, discussed in many patches that MS has put out over the
last year or so.

Try setting your browser security to low and see if that works.

I am having a similar problem with this issue, however my process is starting. The application is not firing though. I am trying to open a pdf file (or even a txt file for that matter) located on the local machine. I have
Process.Start("notepad.exe", @C:\textfile.txt).
Like i said the Process fires, but the application does not. I looked into the browser security settings. Any help is much appreciated.
