Correct Option: C

Which task is accomplished in the Code editor?

  1. Adding forms to the project

  2. Adding controls to the form

  3. Adding event procedures to the form

  4. Both a and b.

  5. All of the above.


Correct Option: C
Explanation:

To solve this question, the user needs to understand the purpose of a code editor and its role in programming.

A code editor is a software application or a part of an integrated development environment (IDE) that allows programmers to write and edit source code. It provides a user-friendly interface for writing, modifying, and organizing code.

Now, let's go through each option and explain what it represents:

A. Adding forms to the project: This option is not accomplished in the code editor. Adding forms to a project typically involves using a visual interface or design view to create and customize forms.

B. Adding controls to the form: This option is accomplished in the code editor. Once a form is created, the programmer can use the code editor to add controls (such as buttons, textboxes, etc.) to the form and specify their properties and behaviors through code.

C. Adding event procedures to the form: This option is accomplished in the code editor. Event procedures define the code that should be executed when a specific event occurs, such as a button click or a form load. The programmer can write and edit these event procedures in the code editor.

D. Both a and b: This option is incorrect. Adding forms to a project is not accomplished in the code editor.

E. All of the above: This option is incorrect. Adding forms to a project is not accomplished in the code editor.

Based on the explanations above, the correct answer is:

C. Adding event procedures to the form.

  1. Online help

  2. WYSIWYG formatting

  3. Dialog boxes

  4. Detailed key strokes and commands

  5. Icons


Correct Option: D

An object is composed of:

  1. properties.

  2. methods.

  3. events.

  4. Both a and b.

  5. All of the above.


Correct Option: E

Which statement about objects is true?

  1. One object is used to create one class.

  2. One class is used to create one object.

  3. One object can create many classes.

  4. One class can create many objects.

  5. There is no relationship between objects and classes.


Correct Option: D

Which is not true about forms and controls in Visual Basic?

  1. They are pre-built.

  2. They are graphical objects.

  3. New versions of the classes must be created with each project.

  4. Buttons can be created with the drag and drop method.

  5. All of the above are true.


Correct Option: C
Explanation:

To solve this question, you need to have an understanding of forms and controls in Visual Basic.

Now let's go through each option and explain whether it is true or not:

A. They are pre-built: This option is true. Forms and controls in Visual Basic are pre-built objects that can be used to create a user interface for an application. These objects are already available in the Visual Basic environment and can be easily added to a project.

B. They are graphical objects: This option is true. Forms and controls in Visual Basic are graphical objects that can be visually designed and manipulated. They can be used to display information, receive user input, and perform various actions.

C. New versions of the classes must be created with each project: This option is not true. In Visual Basic, forms and controls are defined as classes, but you do not need to create new versions of these classes with each project. Instead, you can reuse the existing classes and customize them as needed.

D. Buttons can be created with the drag and drop method: This option is true. In Visual Basic, buttons (which are a type of control) can be easily created by dragging and dropping a button control from the toolbox onto a form. This allows for a simple and intuitive way of adding buttons to a user interface.

Based on the explanations above, the correct answer is:

C. New versions of the classes must be created with each project.

Which is an example of Visual Basic Objects?

  1. Control objects

  2. ASP.NET

  3. ADO.NET

  4. Both a and b.

  5. All of the above.


Correct Option: E
Explanation:

Visual Basic objects are instances of classes that are defined in the Visual Basic programming language. They can be used to represent anything from a simple control on a form to a complex data access object.

Control objects are a type of Visual Basic object that represents a control on a form. Controls are the graphical elements that users interact with, such as buttons, text boxes, and labels.

ASP.NET is a web development framework that uses Visual Basic objects to create dynamic web pages.

ADO.NET is a data access framework that uses Visual Basic objects to access data from databases.

Therefore, the answer to the question is E. All of the above. Control objects, ASP.NET, and ADO.NET are all examples of Visual Basic objects.

Here is a table that summarizes the different types of Visual Basic objects:

Type of object Description
Control object Represents a control on a form
ASP.NET object Represents a web page or web service
ADO.NET object Represents a data source
Other objects There are many other types of Visual Basic objects, such as data structures, mathematical objects, and string objects.

The .Net class library:

  1. contains over 25,000 classes.

  2. uses namespaces to manage all of the classes.

  3. has the System.Form namespace for classes used in Windows-based application.

  4. Both a and b.

  5. All of the above.


Correct Option: D

Which is not a property of the Common control class?

  1. Show

  2. BackColor

  3. Font

  4. ForeColor

  5. Name


Correct Option: A

AI Explanation

To answer this question, we need to understand the properties of the Common control class. Let's go through each option to understand why it is correct or incorrect:

Option A) Show - This option is incorrect because the Show property is a valid property of the Common control class. It is used to determine whether the control is displayed or hidden.

Option B) BackColor - This option is incorrect because the BackColor property is a valid property of the Common control class. It is used to specify the background color of the control.

Option C) Font - This option is incorrect because the Font property is a valid property of the Common control class. It is used to define the font of the control.

Option D) ForeColor - This option is incorrect because the ForeColor property is a valid property of the Common control class. It is used to define the foreground color of the control.

Option E) Name - This option is correct because the Name property is not a property of the Common control class. The Name property is a property of the Control class, which is the base class for the Common control class.

The correct answer is E) Name. This option is correct because the Name property is not a property of the Common control class.

Which property determines whether a control is displayed to the user?

  1. Hide

  2. Show

  3. Visible

  4. Enabled

  5. Cursor


Correct Option: C
Explanation:

To determine whether a control is displayed to the user, the user needs to know the property that controls visibility of the control.

Now, let's go through each option and explain why it is right or wrong:

A. Hide: This property is used to hide a control that is visible on the screen. This option does not determine whether a control is displayed to the user.

B. Show: This property is used to make a hidden control visible on the screen. It does not determine whether a control is displayed to the user.

C. Visible: This property is used to determine whether a control is displayed on the screen. If the Visible property is set to true, then the control is displayed. If it is set to false, then the control is hidden. This option is the correct answer.

D. Enabled: The Enabled property determines whether a control can be interacted with by the user. It does not determine whether a control is displayed to the user.

E. Cursor: The Cursor property determines the appearance of the mouse cursor when it is over the control. It does not determine whether a control is displayed to the user.
