12 Effective Ways To Improve Your Programming

2012-05-15T14:01:00Z

1. Never Stop Learning and Reading
Read books, not just websites.
Read for self-improvement, not just for the latest project.
Read about improving your trade, not just about the latest technology.
Some of the books listed here would be a good start: The most influential programming books of all time

2. Work With People Smarter Than Yourself
Working with smarter and/or more experienced developers will teach you a great deal.

3. Become a Polymath (or 'Jack-of-all-Trades')
Decide to be a 'Jack-of-all-Trades', allowing you to avoid becoming 'pigeon-holed' into one specialty, which can stagnate your programming skills, as well as hurt your future employment prospects.

4. Read and Document Other People's Code
Writing code is significantly easier than reading someone else's code and figuring out what it does.

5. Get Programming Experience on a Real Project
There is nothing like getting in and coding, especially under pressure - work on a real project, with real fickle customers, with real, ever-changing requirements and with real engineering problems.

6. Teach Others About Programming
This will force you to understand something at a completely different level, since you have to explain it to someone else.

7. Learn One New Programming Language Every Year
One year gives you enough time to get past the basics - it pushes you towards understanding what's beneficial in that language, and to be able to program in a style native to that language.

8. Complete One New Pet Project Every Year
Start a "pet" project and follow it to completion and delivery; a good pet project will push your boundaries and keep you interested.

9. Learn Assembly Language
Learning a low level language like assembly gives you insight into the way computers 'think' without any high-level abstractions; the elegance at this level is surprising.

10. See Your Application From the End User's Perspective
Interact with the end-user to see, through their eyes, how they use the software; end users are typically not technical, and they often see software as a magical piece of work, while you see software as a logical set of steps.

11. Start a Physical Exercise Program
You work a whole lot better when you're in good physical shape - problems become easier and less overwhelming, wasting time is much less of a temptation, you can think clearer, and working through things step by step doesn't seem an arduous task.

12. Learn Touch Typing
Learning to touch type is a quick and effective way to give your productivity a boost as a programmer.

connection pools

2012-05-13T12:34:00Z

Each connection pool is associated with a distinct connection string. When a new connection is opened, if the connection string is
not an exact match to an existing pool, a new pool is created. Connections are pooled per process, per application domain, per
connection string, and, when using integrated security, per Windows identity. In this case, the connections are configured to use
integrated security. Each user has a discrete Windows identity resulting in the creation of a connection that is pooled separately.
There is one connection per connection pool.

Entity Framework Cascading Deletes

2012-05-08T06:22:00Z

It’s important to note that a cascading delete in the Entity Framework works only if the de-
pendent entity objects are loaded. This can be accomplished using the Include or Load meth-
ods.

EXAM TIP
For the exam, understand that the XmlReader provides the fastest means to access XML
data and is read-only, forward-only.

Using DataContext to Track Changes and Cache Objects

2012-05-07T03:15:00Z

The DataContext object manages object identity for you so that rows retrieved from the
database table are automatically logged in the DataContext object’s internal identity table
by the row’s primary key when the object is created. If the same row is retrieved again by this
DataContext object, the original instance is handed back to you. Your application sees only
the state of the row that was first retrieved. If, for example, you retrieve a row in your applica-
tion and the row is modified in the database table by a different application, you won’t get
the updated data if you query for this row again because the row is delivered to you from the
DataContext object’s cache.
It might seem rather weird that querying for the same row returned the original state of
the row, even though the row had been changed by another application. In essence, the new
data was thrown away. The reason for this behavior is that LINQ to SQL needs this behavior to
support optimistic concurrency. DataContext contains a method called SubmitChanges, which
sends all your changes back to the database table. This is explained in more detail later in this
lesson.

What Is a Transaction?

2012-05-05T01:47:00Z

Transactions have four essential attributes:
atomicity, consistency, isolation, and durability (known as the ACID attributes).

■   Atomicity The work cannot be broken into smaller parts. Although a transaction
might contain many SQL statements, they must be run as an all-or-nothing proposi-
tion, which means that if a transaction is half complete when an error occurs, the work
reverts to its state prior to the start of the transaction.
■   Consistency A transaction must operate on a consistent view of the data and must
leave the data in a consistent state. Any work in progress must not be visible to other
transactions until the transaction has been committed.
■   Isolation A transaction should appear to be running by itself; the effects of other on-
going transactions must be invisible to this transaction, and the effects of this transac-
tion must be invisible to other ongoing transactions.
■   Durability When a transaction is committed, it must be persisted so it will not be lost
in the event of a power failure or other system failure. Only committed transactions are
recovered during power-up and crash recovery; uncommitted work is rolled back.

DbDataAdapter

2012-05-04T13:28:00Z

When DbDataAdapter is used to retrieve or update data, it examines the status of the con-
nection. If the connection is open, the DbDataAdapter uses the open connection and leaves
the connection open. If the connection is closed, DbDataAdapter opens the connection, uses
it, and then closes it automatically. If you never open the connection, you don’t have to close
the connection. However, if you have many data adapters that will be used in one operation,
you can get better performance by manually opening the connection before you call all the
data adapters; just be sure to close the connection when you’re done.

DbDataReader Object

2012-05-04T13:04:00Z

A DbDataReader object provides a high-performance method of retrieving data from
the data store. It delivers a forward-only, read-only, server-side cursor. This makes the
DbDataReader object an ideal choice for populating ListBox objects and DropDownList ob-
jects.

The DbDataReader object contains a Read method that retrieves data into its buffer. Only
one row of data is ever available at a time, which means that all the data from the database
does not need to be completely read into the application before it is processed.

Storing Encrypted Connection Strings in Web Applications

2012-05-04T08:33:00Z

It’s common
practice to store connection strings in the Web.config file. This makes it easy to change
the connection string without requiring a recompile of the application. However, connec-
tion strings can contain logon information such as user names and passwords. You certainly
don’t want this information to be easily readable by anyone. The solution is to encrypt the
connection strings. You can do this by using the aspnet_regiis.exe utility to encrypt the
connectionStrings section. You can use the /? option to get help on the utility.

You encrypt and decrypt the contents of a Web.config file by using System.Configuration
.DPAPIProtectedConfigurationProvider, which uses the Windows Data Protection API (DPAPI)
to encrypt and decrypt data, or System.Configuration.RSAProtectedConfigurationProvider ,
which uses the RSA encryption algorithm to encrypt and decrypt data.
