hi all

i m starting a Windows based .NET app from my Server (windows based .NET app) app using
Process.Start("C:\Test.exe")

now, i want to control this new application (this new app does not hv any user interface)

1) How to close this app from my app?
2) How to know if this app stops running or closes itself due to some error?




thnx in advance...cheers :)
