Starting 1 to n process(s) and then closing them all later when theapplication exits.

[John Halet]

I have a application that crunches a bunch of data, creating log
files, excel files etc...
I use Process.Start to open any number of these file for viewing.

My goal is to have the application close all the file it opened when
the it exits.

I start files like this for example:
Dim myProcess As Process =
System.Diagnost ics.Process.Sta rt("LatestData. xls")

Later I try to close them like so... Myprocess.Close , however an
exception is thrown saying that the process has already exited. (?But
the file is still open?)

I later have tried
myProcess.Enabl eRaisingEvents = True
AddHandler myProcess.Exite d, AddressOf Me.ProcessExite d
myProcess.Start ("LatestData.xl s")

Friend Sub ProcessExited(B yVal sender As Object, ByVal e As
System.EventArg s)
Dim myProcess As Process = DirectCast(send er, Process)
myProcess.Close ()
End Sub

When I test this setup it seems that seconds after the file is opened
the process exits is closed.
?again the file(s) are still open?

I'm no longer sure that this is the right way to achieve my goal, or
is my implementation not correct?
Not sure...

Any suggestions anyone?
