FORWARD

It is my great pleasure to present this laboratory manual for S.Y (M.C.A)students for the subject of VB.NET (Visual Basic .NET).Subject name itself is

expecting what are the advance tools that might be Visual Studio to developand build rich .NET applications. In this manual we have dealt with VB.NET.

As a student, many of you may be wondering with some of the questions inyour mind regarding the subject and exactly what has been tried is to answer

through this manual.

As you may be aware that MGM has already been awarded with ISO 9000certification and it is our endure to technically equip our students taking theadvantage of the procedural aspects of ISO 9000 Certification.

Faculty members are also advised that covering these aspects in initial stageitself, will greatly relived them in future as much of the load will be taken careby the enthusiasm energies of the students once they are conceptually clear.

LABORATORY MANUAL CONTENTS

This manual is intended for the students S.Y (M.C.A) engineering for the

subject of VB.NET. Subject name itself is expecting what are the advance toolsthat might be Visual Studio to develop and build rich .NET applications. In thesubject of this manual typically contains practical/Lab Sessions we have dealt

with VB.NET.

Students are advised to thoroughly go through this manual rather than onlytopics mentioned are the key to understanding and conceptual visualization oftheoretical aspects covered in the books.

Good Luck for your Enjoyable Laboratory Sessions

SUBJECT INDEX:

1. Create and Validate Login Form.

2. Program to design an ACCOUNT Class.3. Program to demonstrate Inheritance, Polymorphism and Interfaces.4. Advance Controls.5. Common Dialog Controls.6. ADO.NET Code to show records in DataGridView Control.

7. ADO.NET Code to perform Insert, Delete, Update and Select operations.8. Crystal Reports9. Web Application using ASP.NET that uses validation controls.10. Web Application with ADO.NET to perform Insert, Delete, Update andSelect Operations.

DOs and DONT DOs in Laborary:

1. Do not handle any equipment before reading the instructions/Instruction manuals

2. Read carefully the power ratings of the equipment before it is switched on whether ratings 230V/50

Hz or 115V/60 Hz. For Indian equipments, the power ratings are normally 230V/50Hz. If youhave equipment with 115/60 Hz ratings, do not insert power plug, as our normal supply is230V/50 Hz, which will damage the equipment.

3. Observe type of sockets of equipment power to avoid mechanical damage

4. Do not forcefully place connectors to avoid the damage

5. Strictly observe the instructions given by the teacher/Lab Instructor

Instruction for Laboratory Teachers::

1. Submission related to whatever lab work has been completed should be done during the next labsession. The immediate arrangements for printouts related to submission on the day of practical

assignments.

2. Students should be taught for taking the printouts under the observation of lab teacher.

3. The promptness of submission should be encouraged by way of marking and evaluation patternsthat will benefit the sincere students.

2. Lab Exercises:

[Purpose of this exercise is to define a Class ACCOUNT .Include following

Data members: Name of depositor, Account no, type of Account, balance amount.

Member Functions: To Deposit an amount, to withdraw an amount after checking balance, to

show balance.

Also provide proper validations wherever necessary. Write a main program to test above

class]

Steps to follow:

1) In FILE menu select NEW PROJECT. Then select Console Application.

2) Give the name for Project AccountInformation and click OK. Window with

Module1.vb gets generated.

3) From Project Menu select Add Class. Give name to the class i.e. ACCOUNT.

4) Write the code and execute by pressing F5.

3. Lab Exercises:

[Purpose of this exercise is to implement Inheritance, Polymorphism and Interfaces.]

Steps to follow:

1) In FILE menu select NEW PROJECT. Then select Console Application.2) Give the name for Project EmployeeInformation and click OK. Window with

Module1.vb gets generated.

3) From Project Menu select Add Class. Give name to the class i.e. Employee and

define its functions .This class will be BASE Class.

4) From Project Menu again select Add Class. Give name to the class i.e. Manager

.This class should be derived class.

5) From Project Menu again select Add Class. Give name to the class i.e. Engineer .This

class also should be a derived class.

6) Then Right Click on EmployeeInformation in solution explorer window and select

ADD, then select New Item. Then select Interface and give name as ITaxInterface.

Declare the methods in interface and implement interface methods in derived classes.

7) Write the code and execute by pressing F5.

4. Quiz on the subject:

Quiz should be conducted on tips in the laboratory, recent trends and subject knowledge of thesubject. The quiz questions should be formulated such that questions are normally are from the

scope outside of the books. However twisted questions and self formulated questions by thefaculty can be asked but correctness of it is necessarily to be thoroughly checked before theconduction of the quiz.

5. Conduction of Viva-Voce Examinations:

Teacher should oral exams of the students with full preparation. Normally, the objective questionswith guess are to be avoided. To make it meaningful, the questions should be such that depth ofthe students in the subject is tested Oral examinations are to be conducted in co-cordialenvironment amongst the teachers taking the examination. Teachers taking such examinations

should not have ill thoughts about each other and courtesies should be offered to each other in

case of difference of opinion, which should be critically suppressed in front of the students.

7. Evaluation and marking system:

Basic honesty in the evaluation and marking system is absolutely essential and in the processimpartial nature of the evaluator is required in the examination system to become popular amongstthe students. It is a wrong approach or concept to award the students by way of easy marking toget cheap popularity among the students to which they do not deserve. It is a primaryresponsibility of the teacher that right students who are really putting up lot of hard work withright kind of intelligence are correctly awarded.

The marking patterns should be justifiable to the students without any ambiguity and teachershould see that students are faced with unjust circumstances.
