SEMESTER FOURTH
SUBJECT CODE & NAME BT0082 - Visual Basic
BK ID B1093
CREDITS 4
MARKS 60
Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Question. 1. Describe the data types in VB.NET.
Answer: Understandingdataandhowit isrepresentediskeytomakinguse of itina program.In this
segmentwe'll walkthruVB.NETsstandarddatatypesandtalkabout how to make use of them.We'll
alsolookat some of the .NET runtime utilities thatmake itpossible to change data from one type to
another. When you see the word "type" in relation to VB.NET, it essentially means a .NET class. A
"data type," then, is a class used to hold or represent different data values.
You also need to have some understanding of
Question. 2. Explain the event driven applications in VB.NET.
Explain common control events and common form events in
VB.net.
Answer: Visual Basicapplications are event - driven, i.e., they work by responding to the events
that occur on objects.Torespondto an event, we code an event procedure (or event handler)
as shown in Figure below:

2. Question. 3. Describe the concept of Exit Try statement in VB.NET
with an example.
Answer: Syntax
Try
[ tryStatements ]
[ Exit Try ]
[ Catch [ exception [ As type ] ] [ When expression ]
Question. 4. How to objectify your programs?
Answer: Objectsare central to Visual Basicprogramming:Formsandcontrolsare objects. Databases
are objects.If youhave usedVisual Basicfora while,orif youhave worked through the examples in
the documentation, then you have already programmed with objects, but there is a lot more to
objects than what you have seen so far.
In the following topics, you will see how easy it is to create your own objects from the classes you
define and to use objects to simplify your coding and increase code reuse.
Question. 5. Explain the mechanics of Implementation of Interface.
Answer: Objects define their interaction with the outside world through the methods that they
expose.Methodsformthe object'sinterface withthe outside world;the buttonsonthe frontof your
televisionset,forexample,are the interface betweenyouandthe electrical wiringonthe other side
of its plastic casing. You press the "power" button to turn the television on and off.
In its most common form, an interface is a group
Question. 6. Explain the mechanism of thread creation.
Answer: Threads are lightweight processes that appear to run in parallel with your main program.
Unlike aprocessa threadsharesmemoryand data with the rest of the program. The word thread is
a contractionof "threadof execution",youmightliketoimagine arope from which you have frayed
the endand takenone thread.It isstill partof the main rope, but it can be separated from the main
and manipulatedon its own. Note that a program that runs with multiple threads is different from
simply starting multiple instances of the same program, because a Threaded program will have
access tot he same data within the program.
