Visual Basic .NET (VBL).pdf
Introduction Welcome to .NET and Visual Basic .NET.As you already know, .NET is a name for a new strategy: a blueprint for build
ing
applications for the next decade. It’s actually even more than that. It’s Microsoft’s commitment to remain at the top of a rapidly chang
ing
world and give us the tools to address the needs of tomorrow’s comput
ing
. Visual Basic .NET is a language for creat
ing
.NET applications, like many others. It also happens that Visual Basic is the easiest to learn, most productive language (but you already know that). Visual Basic .NET is released shortly after the tenth anniversary of the first version of VB. The original language that changed the landscape of comput
ing
has lasted for 10 years and has enabled more programmers to write Windowsapplication than any other language. Programmers who invested in Visual Basic 10 years ago are in demand today. In the world of comput
ing
, how- ever, th
ing
s change very fast, includ
ing
languages. At some point, they either die, or they evolve into someth
ing
new. Visual Basic was a language designed primarily for develop
ing
Windows applications. It was a simple language, because it managed to hide many of the low-level details of the operat
ing
system. Those who wanted to do more with Visual Basic had to resort to Win- dows API. In a way, earlier versions of Visual Basic were ‘sandboxed’ to protect developers from scary details. Microsoft had to redesign Visual Basic. The old language just didn’t belong in the .NET pic- ture (at least, it wouldn’t integrate very well into the picture). Visual Basic .NET is not VB7; it’s a drastic departure from VB6, but a necessary departure. Visual Basic .NET was designed to take us through the next decade of comput
ing
, and if you want to stay ahead, you will have to invest the time and effort to learn it. The most fundamental component of the .NET initiative is the .NET Framework, or simply the Framework. You can think of the Framework as an enormous collection of functions for just about any programm
ing
task. All draw
ing
methods, for example, are part of the System.Draw
ing
class. To draw a rectangle, you call the DrawRectangle method, pass
ing
the appropriate argu- ments. To create a new folder, you call the CreateDirectory method of the Directory class; to retrieve the files in a folder, you call the GetFiles method of the same object. The Framework contains all the functionality of the operat
ing
system and makes it available to your application through numerous methods. VB was such a success because it was a very simple language. You didn’t have to learn a lot before you could start us
ing
the language. Be
ing
able to access the Framework’s objects means that you’re no longer limited by the language. The new version of the language unlocks the full potential of .NET; now there’s hardly anyth
ing
you can do with another language but can’t do 2877c00.qxd 11/11/01 4:13 PM Page xxiii INTRODUCTION xxiv with Visual Basic. This makes the language as powerful as any other language, but it also makes the learn
ing
curve steeper. The good news is that, if you get started today, you’ll get a head start, which may well last for another decade. Who Should Read This Book? You don’t need to know Visual Basic to read
Master
ing
Visual Basic .NET,but you do need a basic understand
ing
of programm
ing
. You need to know the mean
ing
of variables and functions and how an If…Thenstructure works. This book is addressed to the typical programmer who wants to get the most out of Visual Basic. It covers the topics I feel are of use to most VB programmers, and it does so in depth. Visual Basic .NET is an extremely rich programm
ing
environment, and I’ve had to choose between superficial coverage of many topics and in-depth coverage of fewer topics. To make room for more topics, I have avoided includ
ing
a lot of reference material and lengthy list
ing
s. For example, you won’t find complete project list
ing
s or Form descriptions. I assume you can draw a few controls on a Form and set their properties, and you don’t need long descriptions of the properties of the control. I’m also assum
ing
that you don’t want to read the trivial segments of each application. Instead, the list
ing
s concentrate on the “meaty” part of the code: the procedures that explain the topic at hand. If you want to see the complete list
ing
, it’s all on the CD. The topics covered in this book were chosen to provide a solid understand
ing
of the principles and techniques for develop
ing
applications with Visual Basic. Programm
ing
isn’t about new key- words and functions. I chose the topics I felt every programmer should learn in order to
master
the language. I was also motivated by my desire to present useful, practical examples. You will not find all topics equally interest
ing
or important. My hope is that everyone will find someth
ing
interest
ing
and someth
ing
of value to their daily work—whether it’s an application that maps the folders and files of a drive to a TreeView control, an application that prints tabular data, or an application that saves a collection of objects to a file. Many books offer their readers long, numbered sequences of steps to accomplish someth
ing
. Fol- low
ing
instructions simplifies certain tasks, but programm
ing
isn’t about follow
ing
instructions. It’s about be
ing
creative; it’s about understand
ing
principles and be
ing
able to apply the same techniques in several practical situations. And the way to creatively exploit the power of a language such as Visual Basic .NET is to understand its principles and its programm
ing
model. In many cases, I provide a detailed, step-by-step procedure that will help you accomplish a task, such as design
ing
a menu. But not all tasks are as simple as design
ing
menus. I explain why th
ing
s must be done in a certain way, and I present alternatives and try to connect new topics to those explained earlier in the book. In several chapters, I expand on applications developed in earlier chap- ters. Associat
ing
new knowledge to someth
ing
you have already
master
ed provides positive feedback and a deeper understand
ing
of the language. This book isn’t about the hottest features of the language; it’s about solid programm
ing
tech- niques and practical examples. For example, I’m not go
ing
to show you how to write multithreaded applications. The real challenge with multithreaded applications is their debugg
ing
, which requires substantial experience. Once you
master
the basics of programm
ing
Windowsapplications with Visual Basic .NET and you feel comfortable with the more advanced examples of the book, you will find it easy to catch up with the topics that aren’t discussed.

Visual Basic .NET Transact SQL (VBL).pdf
Transact-SQL In Chapter 20, you builtSQL statements to retrieve and update rows in a database. You also learned all the variations of the SELECT statement. Some restrictions, however, can’t be expressed with a WHERE clause, no matter how complicated. To perform complicated searches, many programmers would rather write an application to retrieve the desired rows, process them, and then display some results. The process
ing
could include runn
ing
totals, formatt
ing
of the query’s output, calculations involv
ing
multiple rows of the same table, and so on. Most database management systems include extensions, which enhance SQL and make it behave more like a programm
ing
language. SQL Server provides a set of statements known as Transact-SQL (T-SQL). T-SQL recognizes statements that fetch rows from one or more tables, flow-control statements like IF…ELSE and WHILE, and numerous functions to manipulate str
ing
s, numeric values, and dates, similar to Visual Basic’s functions. With T-SQL you can do everyth
ing
that can be done with SQL, as well as program these operations. At the very least, you can attach lengthy SQL statements to a database as stored procedures, so that you can call them by name. In addition, you can use parameters, so that the same procedure can act on different data. This chapter is an overview of T-SQL and demonstrates the basic topic with stored proce- dures that perform complicated tasks on the server. We’ll start with the COMPUTE BY state- ment, which allows you to calculate totals on groups of the rows retrieved from the database. This statement looks and feels very much like the straight SQL statements, yet it’s not part of standard SQL. Then we’ll look at T-SQL in depth. If you need to look up a function or how to declare a stored procedure’s arguments, you can use this chapter as reference material. If you’re new to T-SQL, you should read this material, because T-SQL is a powerful language, and if you’re work
ing
with or plan to switch to SQL Server, you’ll need it sooner or later. In addition, you’ll improve your Visual Basic programm
ing
. T-SQL is the native language of SQL Server. By see
ing
how the basic operations can be implemented in T-SQL and VB, you’ll gain a deeper under- stand
ing
of database programm
ing
.

Visual Basic .NET VB NET Functions (VBL).pdf
Bonus Reference VB.NET Functions and Statements This bonus reference describesthe functions and statements that are supported by Visual Basic .NET, grouped by category. When you’re search
ing
for the statement to open a file, you probably want to locate all file I/O commands in one place. This is exactly how this reference is organized. Moreover, by group
ing
all related functions and statements in one place, I can present examples that combine more than one function or statement. The majority of the functions are the same as in VB6. One difference is that many of the VB6 statements are implemented as functions in VB.NET. Moreover, many VB6 functions have an equivalent method in a Framework class. VB programmers are so accustomed to the old func- tions that they will not consider the alternatives—at least for a while. The Len() function of VB6 returns the length of a str
ing
. In VB.NET you can retrieve the length of a str
ing
with the Length method of a str
ing
variable. If strVaris declared as str
ing
variable, you can retrieve its length by call
ing
the Length method: Dim strVar As Str
ing
= “a short str
ing
” Console.WriteLine(“The str
ing
contains “ & strVar.Length & “ characters”) Or you can call the Len() function pass
ing
the name of the str
ing
as argument: Dim strVar As Str
ing
= “a short str
ing
” Console.WriteLine(“The str
ing
contains “ & Len(strVar) & “ characters”) Most of the built-in functions are VB6 functions, and they accept optional arguments. VB.NET uses overloaded forms of the same function, and this is an important difference you have to keep in mind as you work with the built-in functions. If you omit an optional argument, you must still insert the comma to indicate that an argument is miss
ing
. Optional arguments are enclosed in square brackets. The Mid() function, for example, extracts a number of characters from a str
ing
, and its syntax is newStr
ing
= Mid(str
ing
[, start][, length]) The start
ing
location of the characters to be extracted is specified by the startargument, and the number of characters to be extracted is length. If you omit the startargument, the extraction starts with the first character in the str
ing
. If you omit the lengthargument, all the characters from the specified position to the end of the str
ing
are extracted. The only mandatory argument is the first one, which is the str
ing
from which the characters will be extracted, and this argument can’t be omitted. The methods of the various classes are discussed in detail in the book. This bonus reference con- tains all the functions supported by VB.NET, and these functions are listed by category in Table 1. Items in the table that are not followed by parentheses are statements and are also described in this reference.
