I am building a web application to gather user information then launch a
process to calculate results. The process is a 3rd Party executable. I
cannot get the process to start. Is there a problem with this code?
Public Overloads Shared Function StartApplicatio n(ByVal fileName As String,
ByVal myPath As String) As Process
Try
Dim WtDistrib As New Process
WtDistrib.Start Info.Verb = "Execute"
WtDistrib.Start Info.CreateNoWi ndow = True
Dim SI As New
ProcessStartInf o("C:\Inetpub\w wwroot\Uniformi ty\ProcessStuff \WtDistrib.exe" )
WtDistrib.Start (SI)
WtDistrib.WaitF orExit()
Console.WriteLi ne(WtDistrib.Ex itCode)
Console.WriteLi ne("WtDistrib.e xe was closed at: " &
WtDistrib.ExitT ime & ".")
WtDistrib.Close ()
Catch e As Exception
Debug.Write("Er ror: " + e.Message)
Console.WriteLi ne("The following exception was raised: " +
e.Message)
End Try
End Function

Don't use Console.WriteLi ne in a method that's supposed to work in an ASP.NET
web app.
You could use System.Diagnost ics.Debug.Write Line if you want.

Caroline,
Why is the return type from this method "Process"? That doesn't make sense.
There shouldn't be a return type (or if there is , perhaps boolean for
success, I suppose).
Have you stepped through your code in the debugger? What happens when you do?

I dropped the Process return type.
When I step through, an exception is thrown at
WtDistrib.WaitF orExit()
"No thread is associated with this process."
The example I posted is only one of several that I have tried. This is my
first asp.net application.

Couple ideas here:
1) try doing this the "easy way"
Process.Start(" C:\Inetpub\wwwr oot\Uniformity\ ProcessStuff\Wt Distrib.exe")
If that doesn't work, you may have a permissions issue. ASP.NET by default
runs under weak credentials. You could add
<identity impersonate="tr ue" userName="stron gaccountname" password = "pass" />
to the web.config.
Where "strongaccountn ame" is an account that you know has permission to
execute in the respective directory.
Hope that helps,
Peter

Hi Caroline,
Thanks for posting!
As Peter mentioned, you can use the impersonation for the current ASP.NET
application. There is a KB article from Microsoft support site demonstrates
how to approach this. Please follow the link below: http://support.microsoft.com/kb/306158/en-us/
Hope this will be helpful!

Thank you. Your input was very helpful.
I had tried impersonation, but I am developping in a Windows 2000
environment, which explains why I failed. It is good to know that
impersonation WILL work though.
I will move my project to the 2003 Server today and see if I have more luck
with impersonation there.

Hi Caroline,
Thanks for your reply!
From your description, I have a little confusion about the current issue.
You said "which explains why I failed". My understanding for this is that
you use the impersonation on Windows 2000 is failed. If I have
misunderstood anything, please let me know.
In my opinion, the impersonation is not for the specific environment. Both
Windows 2000 and Windows 2003 are appropriated for the current issue. So,
if the application runs well under the impersonation on Windows 2000, I
think it also runs well on Windows 2003.
In addition, I'll look forward your reply. Please don't hesitate to let me
know the result. It's my pleasure to be assistance.

The process will not run on the 2003 server either.
I can write to an input file in the directory, but the exe never runs.

Dll written in VB.NET 2003 to start a command remotely.
You can :
- launch the command and wait until it's finished. (Ex. 1)
- launch the command providing a timeout in seconds, it will wait until
it's finished. If the command didn't terminate within the timeout, the
command is killed. (Ex. 2)
- launch the command and continue your processing after the command has
been started remotely (Ex. 3).
