Newbie to .net with a problem

I could do this is VB6 but can't figure out .net yet.

I need to be able to access a data file that has a list of printers, with
their corrisponding share name and computer that they are sat on (Which I
have already generated as a CSV file).

In VB6 I would use the data control to load this in to an array but can't
find the corrisponding function in .net

What I would then do would be to have an array of buttons that would be
created with the names of the printers.

When a button was clicked, it would then execute the following

\\<servername>\netlogon\con2prt /cd \\<printerserver>\<printershare>


I'm not asking anyone to generate me the solution to this, but a few good
pointers would be really appreciated.

Many thanks,
Gareth
 
Gareth,

File operations can be performed on a text (CSV) file as follows:

'read and process CSV file one line at a time
Public Sub ReadFromCSV(ByVal strCSVFilePath As String)
Dim strmInfile As New System.IO.StreamReader(strCSVFilePath)
dim strLine as string
dim strElements() as string

Me.Cursor.Current = Cursors.WaitCursor

'read line
strLine = strmInfile.ReadLine

While Not strLine Is Nothing
Try
'split comma separated line into elements of string array
strElements=strLine.Split(",")

'you write this function/sub
DoSomethingWithThem(strElements)

'get next line
strLine = strmInfile.ReadLine
Catch ex As System.Exception
MsgBox(ex.Message, MsgBoxStyle.Exclamation, "ERROR Reading
file")
Me.Cursor.Current = Cursors.Default
exit Sub
Finally
strmInfile.close
End Try
End While

strmInfile.Close()
Me.Cursor.Current = Cursors.Default
End Sub

IN DOTNET THERE ARE NO CONTROL ARRAYS but one Click event handler can be
told to handle all button click events,

or using AddHandler you can accomplish the same thing when you create the
buttons.

Inside this handler--either way--you can decide based on the button tag or
name or whatever, what to do--maybe store this printer info in the tag of
the button.

Class

In Visual Basic 6.0, the Printers collection was used to return information
about available printers on a system. In Visual Basic .NET, the PrintDialog
control returns information about available printers; properties for a given
printer can be retrieved using the PrinterSettings class.

The Printers collection had two properties: Item and Count. These were
standard collection properties; the PrintDialog control has no equivalent
properties.

Hope this helps you some,

Is that a command shell command? Have a look at this project, maybe it
will help you to solve your problem:
