How do I access a custom section in a custom section group? I was hoping to have something like this:
<br />
<configuration><br />
<configSections><br />
<sectionGroup name="mySectionGroup"><br />
<section name="mySection" type="System.Configuration.NameValueSectionHandler,System" /><br />
</sectionGroup><br />
</configSections><br />
<br />
<mySectionGroup><br />
<mySection setting1="value1" setting2="value2" /><br />
</mySectionGroup><br />
</configuration><br />

Like what? Make sure you use the < and > buttons at the botrom of the message box when you post here. Anything in < > characters will be treated like HTML tags and not displayed.

Ok. Sorry about that. After doing some research I got what I wanted. Related question: Can I have multiple sections in a sectionGroup? Like this?
<br />
<?xml version="1.0" encoding="utf-8" ?><br />
<configuration><br />
<configSections><br />
<sectionGroup name="CustomSectionGroup"><br />
<section name="CustomSection" type="System.Configuration.SingleTagSectionHandler" /><br />
<section name="CustomSection2" type="System.Configuration.NameValueSection" /><br />
</sectionGroup><br />
</configSections><br />
<CustomSectionGroup><br />
<CustomSection setting1="value1" setting2="value2" /><br />
<CustomSection2><br />
<add key="key1" value="value1"><br />
<add key="key2" value="value2"><br />
</ CustomSection2><br />
</CustomSectionGroup><br />
</configuration><br />

Yes, you can. You have to use ConfigurationSettings.GetConfig() to access a custom configuration section. You might want to look at this[^] on MSDN for an example and what the limitions are.

 Hi Everyone
Im a new programmer who has just recently (4mths) have purchased Visual Basic 2003 and about 75% through the Step by Step Visual basic book learning how to use it etc.
Im now looking for ideas, to making a programme on a bitmap of Europe, moving Icons on the map (units) from area to provincial area, with a basic data base, political moves with up to 7 players moving on the internet.
Its the moving the Icons on the Map at the moment is the problem initially. I was thinking of left clicking the unit icon, then right clicking the adjacent area to make the move, but how?
Anyhow I bow to more experienced programmers out here to help me out.

I wouldn't put anything on the right button except a context menu.
You might consider a drag-and-drop style of movement which people would be more familiar.

I seem to be running into recurring problems with doing book exercises where my code looks exactly the same as the author's, but theirs works and mine has some sort of syntax error.
my latest is:
"Too many arguments to Public Sub New()"
The bolded line has the blue squiggly under (Me)
<br />
Private Sub Button1_Click(ByVal sender As System.Object, _<br />
ByVal e As System.EventArgs) Handles Button1.Click<br />
<br />
Dim f2 As New Form2(Me)<br />
f2.Show()<br />
Me.Hide()<br />
<br />
End Sub<br />
<br />
Private Sub Button2_Click(ByVal sender As System.Object, _<br />
ByVal e As System.EventArgs) Handles Button2.Click<br />
<br />
Dim f2 As New Form2<br />
f2.Show()<br />
<br />
<br />
End Sub<br />
End Class<br />
Granted, there is another form involved here with similar code.

You need to change the constructor of the form 'form2' such that it accepts a parameter of type 'form1' if you are in the current form.
Constructor of the form 'form2' goes like this
Sub New ( f as Form1 )
...Code goes here
End Sub

You don't need the Me in the constructor for Form2, unless you intend on passing Form1 as a reference to Form2 for some reason. Usually this would be because Form2 has code on it that modifies the instance, or controls, on Form1.

While I am beginning to become more intuitive with the code, the "me" is printed in the book just as I typed it.

Where did this book come from? It sounds like it has a mountain of errors in it...

It's actually several books. That's what worries me.
One is Visual Basic.Net Step-by-Step by Mike Halvorson, one is Visual Basic.Net Programming by Peter Aiken, and the other one is the MCAD/MCSD Windows Aps with VB.Net and C# 2nd Edition.
None of them have caused any sort of major exceptions, but I've had to do some sort of "tweaking" to my code to avoid syntax errors that they don't seem to have.
So in one way, I'm learning how to improvise, but in another, I'm not getting the same results as these (so called) experts in the field.

Out of curiosity, is it possible to identify which classes are almost always referenced in a VB.NET assembly, and just add them to every project?
If so, what might those classes be?

Classes or Namespaces?
It's entirely up to you. You could go an add ALL the namespaces to each project, but some of them will require you to add the references for them too.
You would have to make your own project templates to add these to every project you make though. You can't tell VS.NET to just add these namespaces to every project, they must be put into the project templates.
When the project is built, all the unnecessary references and namespaces are ignored and not put into the final .EXE or .DLL.

Perhaps I still don't understand the differences between classes and namespaces. I thought the namespaces pointed to the classes (and structures).

Namespaces, I would say to categorize a set of classes. Say, you have classes SqlClient, OracleClient. These two belong to Data manipulation. So, they can be a part of the namespace Data. code may go like this
Namespace System.Data
Public Class SqlClient
Sub SqlConnection ()
End Sub
End Class
Public Class OracleClient
Sub OracleConnection()
End Sub
End Class
End Namespace
Here in this case, if you import System.Data you will have access to both SqlClient and OracleClient classes directly.
Else if you just import System Namespace, you will have to refer to these classes as follows
Dim s as Data.SqlClient
Dim o as Data.OracleClient
I would say namespaces or just for the sake of simplicity in code. So, one namespace is a group of multiple classes.

Thanks for that explaination. It makes more sense now.

A namespace is a collection of related classes.
You don't instantiate a namepsace, but you do to use a class.

This harkens back to my Excel.Interop issue.
The book example (and the CD file examples) have just the shortened namespace includes at the top, but I had to use the fully qualified namespace in order to get the syntax errors to go away. I can find nothing in the example code that differs from mine, but they don't seem to have to use the full names.

Visual Basic .NET Step-By-Step and then Visual Basic .NET Programming by Peter Aiken.
Taking the (me) out and leaving just () worked, but I had to manually stop the program when I was done, not just by using the x, but by using the stop option in the Debug menu. There are two forms, one has two command buttons, the first command button opens the second form and closes the first, the second command button opens the second form but doesn't close the first. The second form only has a command button for closing itself.
It was kind of strange, I was looking at the MCSD/MCAD Windows Applications book too, and there was a garbage collection demo that stored so many bits into memory and supposidly if I sat there long enough and waited, it would start to destroy them. I waited...and waited...and waited. Nothing.
I just cleaned off my primary drive and reinstalled Win2K about a month ago (I have XP Pro on my laptop).

I have a vb.net windows application which sends out faxes. It works OK but it seems like the Fax service on Win 2000 hangs after a while. It works fine, as soon as the machine is re-booted. I'm not sure whats causing this. Is there some setting to set the fax service right? Or is my code causing probs?
This is my code:
FaxSvr.Connect(Environment.MachineName.Trim)
FaxSvr.Retries = 10
FaxSvr.RetryDelay = 1
Doc = FaxSvr.CreateDocument(DocPath)
Doc.FaxNumber = Global.FaxNumPrefix & Recipient.RcptFax
Doc.SenderFax = Sender.SenderFax
Doc.SenderName = Sender.SenderName
hresult = Doc.Send()
Return True
Thanks.
