How to invoke external application through ASP.Net web application

[sandy]

Hi,

I am trying to invoke an external email management
program from my ASP.NET web application. For testing
purposes I created a very simple webform that has a
single button. The code behind has the following:
Sub btnGo_Click(ByV al sender as System.Object, ByVal e as
System.EventArg s) Handles btnGo.Click
Dim objInfo As New ProcessStartInf o()
objInfo.FileNam e = "c:\program files\gammadyne
mailer\gm.exe"
objInfo.Argumen ts = "/t e:\temp\cba\eec m.txt"
Dim objProc As New Process()
objProc.Start(o bjInfo)
End Sub
When I click on the Go button, I can see gm.exe in the
Task Manager, but nothing happens. The program doesnt
send out the email like it's supposed to. When I use the
same piece of code in a Windows Application or a Windows
Service it works just fine.
I know this has to do with the security of the ASPNET
user, but I have also tried executing the webform and the
web application under a different user that belongs to
the Administrators group, but with the same result. So I
don't know what to do, please advice.
Regards,

Sandeep

Hello Sandy,

Do u use impersonalizati on to start external app?

There is a number reasons why it doesnt work, because by default the asp.net
account has no rights to interact with desktop and with network resources.

Ideally it's not a good way to start ext app from ASP.net
