Running a process from ASP.NET

J

John

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)

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.

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.
