The Rise of Classes, Methods, Objects
In computer languages, often a function definition looks like this:

variables ...

I have a situation where an app writes data of various types (primitives and
objects) into a single dimensional array of objects. (This array eventually
becomes a row in a data table, but that's another story.) The data is
written once and then read many times. Each primitive read requires
unboxing. The data reads are critical to overall app performance. In the
hopes of improving performance, we have tried to find a way to avoid the...

The C# 3.0 spec (http://msdn.microsoft.com/vcsharp/future/) contains a
feature called "Implicitly typed local variables".
The type of the variable is determined at compile time based on the
expression to the right of the = sign:
var s = "Hello"; //s is strongly typed to be a string
var i = 25; //i is strongly typed to be an integer
But what I don't understand what advantage it is?

I've created a strongly typed DataSet (Customers.xsd) using the xsd.exe
tool. I want to be able to access fields using
ds.Customer.CompanyName.
The problem is when I return this DataSet from a Web Service it adds
another Table to the DataSet that contains the data. I have to access
the data using ds.Tables.Rows.ToString(). This
defeats the whole purpose of using a strongly typed DataSet.
Thanks in advance for the help.

I use the following code for a strongly typed arraylist and it works great.
However, I was wondering if this is the proper way to do it. I realize that
if I want to implement sorting of the arraylist then I have to handle this
with a sort method that uses comparer. I can reference the properties of the
Arraylist directly such as
dim mylist as new FrameList
mylist.Add(new FrameStructure)
mylist(0).first = "blabla..."
mylist(0).second...

in March, i posted a essay “What is Expressiveness in a Computer
Language”, archived at:
http://xahlee.org/perl-python/what_is_expresiveness.html
I was informed then that there is a academic paper written on this
subject.
On the Expressive Power of Programming Languages, by Matthias

Silly question maybe, but I've been doing the following for far too
long now:
public static DataTable myDataTable()
{
string sql = @"SELECT column1, column2, column3, column4
FROM myTable";
using (SqlConnection conn = new SqlConnection(websqlconn))
{
SqlCommand cmd = new SqlCommand(sql, conn);

Hi,
I have understood Data Sets but what is meant by typed/untyped/
strongly typed datasets. Can any one explain me or suggest any site/
article, to get these concepts (and their comparisions) cleared?
Thanks,
Rachana

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
