What is the best method to achieve this (I am relatively new to
vb.net)? Should I use an ini file or the registry? Is there another
option available in vb.net that is the preferred way? This
application will reside on our network and more than one user could
possibly run it so I don't think the local registry is the answer.
Basically I just want to remember the options the last user chose on
the form and then use those previously used settings the next time the
program is run.

Are the settings for all users or per user ? If the later then use
My.SEttigns and the settings designer.
If for all users, and you are using VB 2008, use XDocument, e.g:
To read:
Dim doc As XDocument = XDocument.Load( "settings.x ml")
Dim setting1 As String = doc...<setting1 >.Value
Dim setting2 As String = doc...<setting2 >.Value
Dim setting3 As String = doc...<setting3 >.Value
To Write:
Dim doc = <?xml version="1.0"?>
<settings>
<setting1>top secret key</setting1>
<setting2>my credit card number</setting2>
<setting3>my social security number</setting3>
</settings>
doc.Save("setti ngs.xml")
Or using placeholders:
Dim doc = <?xml version="1.0"?>
<settings>
<setting1><%= setting1 %></setting1>
<setting2><%= setting2 %></setting2>
<setting3><%= setting3 %></setting3>
</settings>
Okay so I was able to load the XML file. How exactly do I read a node
value? I tried all sort of scenarios of doc...<setting1 >.value like
you instructed but I just can't get it to work. Can you post an exact
example (without ellipse characters)?

You might want to store it somewhere that all users have access to, bearing

From shlobj.h in the Windows Server 2003 SDK, regarding special folder
enumeration:
#define CSIDL_COMMON_AP PDATA 0x0023 // All
Users\Applicati on Data

You appear to be in a country where there are at least 18 months in a
year... perhaps storing the date/time in a format like yyyyMMddThhmmss would
be a good idea.
