I'm using a queue to hold a series of strings that are complete command line
arguments to start the silent/unattended installation of various pieces of
software. Here is some sample code.
1 Dim myProcess as New Process
2 myProcess.Enabl eRaiseEvents = True
3 myProcess.Start Info.Filename = myQ.Dequeue ' The string value in this
instance is "c:\windows XP-KB824146-x86-ENU.exe /u /n /z"
4 Do Until (myProcess.HasE xited = True)
5 Loop
6 AutoLogon() ' Sets various registry keys.
7 RunOnce() ' Sets some more registry keys.
8 Shell("shutdown .exe -r -f -t 05") ' Forces a reboot of the system in 5
seconds.
The problem is that on line 4 it throws an exception "No Process is
associated with this object".
The other problem is that if I take out the do loop entirely the .exe fires
off and begins installation but the program doesn't wait for it to finish.
It immediately move on to 6, 7, and worst of all 8. Then the system reboots
mid-installation.
Is there a good way to make the thing wait until the installation is done
before continuing on? I piddled with Process.ExitCod e as well with no luck.
Thanks in advance. =) 5 8124
I don't see myProcess.Start () anywhere. Looks like that's what you need.
Would be good also to throw in some Sleep() call inside loop.

Hi Ty,
Still going for it. ;-)
If you have the filename and the arguments mixed,
myProcess.Start Info.Filename = myQ.Dequeue
where it's "c:\windows XP-KB824146-x86-ENU.exe /u /n /z",
it will look for a file called
"windowsXP-KB824146-x86-ENU.exe /u /n /z"
which it won't find, of course.
You need to separate the args out and have
myProcess.Start Info.Filename = <just the file path>
myProcess.Start Info.Arguments = <the arguments>
(as well as the Process.Start that Alex mentioned).
Regards,
Fergus

Here is a stupid little example....

Imports System.Diagnost ics
Module Module1
Private Class Command
Public Sub New(ByVal cmd As String, ByVal args As String)
Me.cmd = cmd
Me.args = args
End Sub
Public cmd As String
Public args As String
End Class
Sub Main()
Dim cmds() As Command = {New Command("cmd", "/c dir c:\windows
/p"), New Command("cmd", "/k echo hello, world")}
Dim q As New Queue(cmds)
Dim cmd As Command
Dim p As Process
Do While q.Count > 0
cmd = DirectCast(q.De queue(), Command)
p = Process.Start(c md.cmd, cmd.args)
p.WaitForExit()
Loop
End Sub
End Module

Ok, I'm now trying to use enumerator to put what is still in my queue into
