Trying to run a program using a Queue.

[Ty Moffett]

I am trying to write a little app that will perform unattended installations
of various software packages. I have a text file, each line is a string
containing the complete command to start a silent/unattended install. I
have successfully read the entire file and each line gets added to the
queue. On this line "myProcess.StartInfo.FileName(myQ.Dequeue)" i get an
error: C:\Documents and Settings\tmoffett\My Documents\Visual Studio
Projects\HandsOff\Module1.vb(36): Property access must assign to the
property or use its value.

Is there a better way to go about this?
Thanks in advance.

Imports System.Collections

Imports System.Object

' Run the program

' read the first command from the queue

' run the command

' remove the item from the queue

' rerun the program until the queue is empty

Module HandsOff

Public Sub main()

Dim fs As New FileStream("c:\HandsOff.txt", FileMode.OpenOrCreate)

Dim sr As New StreamReader(fs)

Dim line As String

line = sr.ReadLine()

Dim myQ As New Queue

Do Until line = Nothing

myQ.Enqueue(line)

line = sr.ReadLine

Loop

' Displays the properties and values of the Queue.

Console.WriteLine("myQ")

Console.WriteLine(ControlChars.Tab + "Count: {0}", myQ.Count)

Console.Write(ControlChars.Tab + "Values:")

PrintValues(myQ)

Do While myQ.Count > 0

Dim myProcess As New Process

myProcess.StartInfo.FileName(myQ.Dequeue)

myProcess.Start()

'Shell(myQ.Dequeue())

'Registry hacks to enable automatic logon upon reboot

AutoLogon()

Shell("shutdown.exe -r -f -t 05")

Hi Ty,

myProcess.StartInfo.FileName(myQ.Dequeue)

StartInfo.FileName is a Property as mentioned in the error message. This
means that its like a variable and must be used as such (use its value
somewhere or set it).

The line above is simlar to this:
Dim sYourName
sYourName ("Ty")

I'm sure, looking at this with an ordinary string, you can see that it's
wrong and should be:
sYourName = "Ty"

Simlarly you need:
myProcess.StartInfo.FileName = myQ.Dequeue
