- 7. GUI Application Development using VB.Net (22034) Maharashtra state Board of Technical Education i Preface The primary focus of any engineering laboratory work in the technical education system is to develop the much-needed industry relevant competencies and skills. With this in view, MSBTE embarked on this innovative „I‟ scheme curricula for engineering diploma programmes with outcome-based education as the focus and accordingly, relatively large amount of time is allotted for the practical work. This displays the great importance of the laboratory work making each teacher, instructor & student to realize that every minute of the laboratory time need to be effectively utilized to develop these outcomes, rather than doing other mundane activities. Therefore, for the successful implementation of this outcome-based curriculum every practical has been designed to serve as „vehicle‟ to develop this industry identified competency in every student. The practical skills are difficult to develop through „chalk and duster‟ activity in the classroom situation. Accordingly, the „I‟ scheme laboratory manual development team designed the practicals to focus on the outcomes, rather than traditional age old practice of conducting practical‟s to „verify the theory‟ (which may become a byproduct along the way) This laboratory manual is designed to help all stakeholders, especially the students, teachers and instructors to develop in the student the pre-determined outcomes. It is expected from each student that at least a day in advance, they have to thoroughly read through the theoretical background associated with practical. Every practical in this manual begins by identifying the competency, industry relevant skills, course outcomes and practical outcomes which serve as a key focal point doing the practical. The students will then become aware about the skills they will achieve through procedure shown there and necessary precautions to be taken, which will help them to apply in solving real-world problems in their professional life. This manual also provides guidelines to the teachers and instructors to effectively facilitate student-centered lab activities through each practical exercise by arranging and managing necessary resources in order that the students follow the procedures and precautions systematically ensuring achievement of outcomes in the students. This course provides an introduction to the VB.NET. It is the programming language based on Object Oriented Concepts which is prominently used to develop GUI based Applications. Graphical User Interface (GUI) based application includes various user friendly controls to accept or display data. This course will give the students an in-depth understanding of the concepts used in VB .NET and necessary skills to use programming techniques to develop .NET based applications and deploy the same. Although best possible care has been taken to check for errors (if any) in this laboratory manual, perfection may elude as this is the first edition of this manual. Any errors and suggestions for improvement are solicited and highly welcome.

- 23. GUI Application Development using VB.Net (22034) Maharashtra state Board of Technical Education 7 Practical No. 2: Design VB.NET application using Existing Namespaces and User Defined Namespace. I. Practical Significance Namespaces organize the objects defined in an assembly. Assemblies can contain multiple namespaces, which can in turn contain other namespaces. Namespaces prevent ambiguity and simplify references when using large groups of objects such as class libraries. II. Relevant Program Outcomes (POs) Basic knowledge: Apply knowledge of mathematics and engineering as it applies to the field of computer software and hardware. Discipline knowledge: To apply knowledge of computer engineering field to solve core and applied engineering problems. Experiments and practice: Able to plan and perform experiments and practices with its results to solve computer engineering problems. Engineering tools: Formulate and solve problems related to computer engineering field using appropriate techniques/tools. III. Competency and Practical skills This practical expects to develop the following skills in the student. Develop VB.NET programs to solve computer group related problems. 1. Write a VB.NET program to use of Namespaces. 2. Compile/Debug/Save the „VB.NET‟ program. IV. Relevant Course Outcome(s) Use Visual Studio IDE to design application V. Practical Outcome (PrOs) Develop a .Net program using existing & user defined Namespace in VB.net Application. VI. Relevant Affective domain related Outcome(s) 1. Follow safety measures. 2. Follow ethical practices VII. Minimum Theoretical Background Namespaces make it possible to organize the thousands of .NET Framework objects and all the objects that VB programmers create in projects so they don't clash. For example, if you search .NET for a Color object, you find two. There is a Color object in both: System.Drawing System.Windows.Media If you add an Imports statement for both namespaces (a reference may also be necessary in the project properties) ... Imports System.Drawing Imports System.Windows.Media ... then a statement like ... Dim a As Color
- 24. GUI Application Development using VB.Net (22034) Maharashtra state Board of Technical Education 8 ... will be flagged as an error with the note, "Color is ambiguous" and .NET will point out that both namespaces contain an object with that name. This kind of error is called a "name collision." This is the real reason for "namespaces" and it's also the way namespaces are used in other technologies (such as XML). Namespaces make it possible to use the same object name, such as Color, when the name fits and still keep things organized. You could define a Color object in your own code and keep it distinct from the ones in .NET (or the code of other programmers). Namespace MyColor Public Class Color Sub Color() ' Do something End Sub End Class End Namespace You can also use the Color object somewhere else in your program like this: Dim c As New MyColor.Color c.Color() Before getting into some of the other features, be aware that every project is contained in a namespace. VB.NET uses the name of your project (WindowsApplication1 for a standard forms application if you don't change it) as the default namespace. VIII.
