ASSIGNMENT

DRIVE	FALL 2016
PROGRAM	BSc IT
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: Understanding data and how it is represented is key to making use of it in a program. In this segment we'll walk thru VB.NETs standard data types and talk about how to make use of them. We'll also look at some of the .NET runtime utilities that make it possible 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 Basic applications  are  event - driven,  i.e.,  they  work  by  responding to the events that occur on objects. To respond to  an  event,  we  code  an  event  procedure  (or  event  handler)  as  shown in Figure  below:

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: Objects are central to Visual Basic programming: Forms and controls are objects. Databases are objects. If you have used Visual Basic for a while, or if you have 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. Methods form the object's interface with the outside world; the buttons on the front of your television set, for example, are the interface between you and the electrical wiring on the 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 a process a thread shares memory and data with the rest of the program. The word thread is a contraction of "thread of execution", you might like to imagine a rope from which you have frayed the end and taken one thread. It is still part of the main rope, but it can be separated from the main and manipulated on 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.
