Question 1

The number of different colors used on a form should be limited to ____ colors exclusive of black, white, and gray.
A) two
B) three
C) four
D) five

Accepted Answer

Limiting the number of different colors to three, exclusive of black, white, and gray, creates a visually appealing and easy-to-read form. Using too many colors can make the form look cluttered and confuse the user.

Question 2

A ____ provides an area in the form for the user to enter data.
A) text box
B) label
C) button
D) check box

Accepted Answer

A text box is specifically designed to allow the user to input data in the form of text. Labels provide text information, buttons execute commands, and check boxes are used for selecting multiple options.

Question 3

A control's border is determined by its BorderStyle property.

Accepted Answer

The BorderStyle property of a control determines the style of its border.

Question 4

You should never use a dark color background or a light color font.

Accepted Answer

Using a dark background with light font or a light background with dark font makes it difficult to read and can strain the eyes, which is not good for user experience. It's better to use a high contrast color scheme, where the font and background colors are significantly different from each other.

Question 5

A label control used to display output should use which of the following BorderStyle settings?
A) FixedSingle
B) Fixed3D
C) No BorderStyle (None)
D) Sizable

Accepted Answer

The FixedSingle BorderStyle provides a simple border around the label without any raised or sunken effects, making it a good choice for displaying output.

Question 6

A label control's ____ property determines whether the control automatically sizes to fit its current contents.
A) TextAlign
B) Fit
C) MiddleCenter
D) AutoSize

Accepted Answer

The AutoSize property determines whether the label control automatically adjusts its size to fit the text it contains. This can be useful if the text is dynamic and may change in length or content.

Question 7

The last step in planning an OO application is to ____.
A) draw a sketch of the user interface
B) identify the objects to which tasks will be assigned
C) identify the tasks the application needs to perform
D) identify the event required to trigger an object to perform its assigned tasks

Accepted Answer

The last step in planning an OO application is often to draw a sketch of the user interface to ensure that the application's intended functionality is accurately reflected in the design. However, all other options listed (identifying objects, tasks, and events) are important steps in the planning process as well.

Question 8

Which of the following is the correct sequence of events when designing a solution?
A) Write the code, design the interface, and plan the application.
B) Design the interface, plan the application, and write the code.
C) Plan the application, write the code, and design the interface.
D) Plan the application, design the interface, and write the code.

Accepted Answer

When designing a solution, it is best to start with planning what the application should do, then design the interface to ensure it meets the needs of the user, and finally write the code that will implement the planned application and interface design. This ensures a clear understanding of what the application needs to accomplish before trying to implement it, and also allows for the interface design to be informed by the planned functionality.

Question 9

An instruction that is syntactically correct will also be logically correct.

Accepted Answer

Syntax and logic are different concepts in programming. A program can have correct syntax but have logical errors, resulting in incorrect output.

Question 10

Most invalid data is a result of typing errors that occur when entering instructions.

Accepted Answer

Typing errors can result in incorrect or incomplete data being entered, leading to invalid data.

Question 11

In most cases, an identifying label should be from one to three words only and appear on one line.

Accepted Answer

Keeping identifying labels short and on one line helps with readability and organization.

Question 12

An access key allows the user to select an object using the ____ key in combination with a letter or number.
A) Shift
B) Tab
C) Alt
D) Backspace

Accepted Answer

An access key is a keyboard shortcut that allows the user to select an object using the Alt key in combination with a letter or number. This is often used in applications or websites to provide quick access to certain commands or options. Shift is typically used for selecting multiple objects or text; Tab is used for moving between fields or controls; and Backspace is used for deleting or going back.

Question 13

The ____ property of a control is used to specify the position of the text within the control.
A) AlignText
B) Alignment
C) Justify
D) TextAlign

Accepted Answer

The TextAlign property of a control is specifically used to specify the position of the text within the control. AlignText and Alignment are not valid properties in most programming languages and Justify is typically used to refer to text alignment in paragraphs, not individual controls.

Question 14

Labels that identify other controls (such as text boxes) should be right-aligned according to Windows standards.

Accepted Answer

According to Windows standards, labels for text boxes and other controls should be left-aligned to improve readability and scanability.

Question 15

The first step in planning an OO application is to ____.
A) draw a sketch of the user interface
B) identify the objects to which tasks will be assigned
C) identify the tasks the application needs to perform
D) identify the event required to trigger an object to perform its assigned tasks

Question 16

To test an application, you should use both valid and invalid test data.

Accepted Answer

Using both valid and invalid test data allows for a more thorough examination of an application's functionality and potential vulnerabilities. Valid test data tests if the application can handle expected inputs and outputs, while invalid test data tests if the application can handle unexpected or incorrect inputs and outputs.

Question 17

You can hide a control on a form while an application is running by changing the Visible property from False to True.

Accepted Answer

To hide a control on a form while an application is running, you would change the Visible property from True to False, not the other way around.

Question 18

The first step in the planning phase of a programming solution is to sketch the user interface.

Accepted Answer

The first step in the planning phase of a programming solution is to analyze the problem and determine the requirements. Sketching the user interface comes later in the design phase.

Question 19

The programming process begins with a meeting between the programmer and the client. Which of the following activities would be the last activity in the programming process?
A) Build the user interface.
B) Code the application.
C) Test and debug.
D) Assemble the documentation.

Accepted Answer

Assembling the documentation should be the last activity in the programming process. This includes user manuals, technical documentation, and other necessary material to ensure that the client has a complete understanding of the application.

Question 20

The Windows standard is to use sentence capitalization for identifying labels.

Accepted Answer

This is correct. In Windows, sentence capitalization is used for identifying labels. For example, "File," "Edit," "View," etc.
