What does the vb statement mean?

[=?Utf-8?B?UGV0ZXI=?=]

Dim sCoName As String = oDs.Customers(0).CompanyName

The part that I want to understand is the oDs.Customers(0). Does
oDs.Customers(0) mean 1st row of the datatable Customers. Where can I find
more information about this?

Well, I have found that this is something called collection's index. I find
the information in here:
http://msdn2.microsoft.com/en-us/lib...d6(VS.80).aspx.

Besides collection's index, it mentions that I can do the same thing using
collection-specific statements in your programming language. How to do that
in VB?

In general, it's a Default property. You can call a Default property by
omitting the property name. For example, if a class' Default property is
"Item", you can write

theObject.Item(Index)

or

theObject(Index)
A Default property is declared by using the Default keyword:

Default Public Property Item(ByVal Index As Integer) As Object

A class (a type) can only have one Default property. It is often used
whenever the nature of the class is something that contains items, similar
to an array whose items can also be accessed by the syntax
"TheArray(Index)".

It's purpose is just having less to type.

Peter,

This is exactly as you and Armin say. However to add a little bit. What you
show is the part of a generated XSD file. Called a dataset. With Visual
Studio you can generate from an XSD file a class (in VBNet, C# or the other
2 supported languages).

If you instance from that class an object, than you can use it like you do.

To see that class you have in your Solution Explorer in top to set Show all
files.

Than you can open the class and have a look at it. For to make an XSD file
has Visual Studio a lot of tools.

Hi Cor,

How can I find out the default property of a class like DataTable, Dataset,
and etc.? I hope one does not need to review coding. I try to look at MSDN
Library for the default property for DataTable class and do not find
anything. I cannot even find the Item property for DataTable class.

There is no Item property for DataTable. Rows() is the default
property.

property.

A DataTable does not have a Default property, but the Rows property,
pointing to a DataRowCollection, does have the Item property as Default
property ("dt.rows(index)").
