Question 1

It's a good programming practice to test a procedure after you have coded it.

Accepted Answer

Testing a procedure after coding ensures that it works as expected and helps in identifying and fixing any errors or bugs early in the development process.

Question 2

The programmer uses an object's location to refer to the object in code.

Accepted Answer

In code, a programmer refers to an object through its reference or variable name, not its memory location. The reference acts as a handle to access the object's properties and methods.

Question 3

An identifying label should be from one to three words only, with the entire label appearing on one line.

Accepted Answer

An identifying label is typically concise and should fit within one line for clarity and readability, often consisting of one to three words.

Question 4

The ____ key allows the user to select a menu using the Alt key in combination with a letter or number.

Accepted Answer

The correct term is "access key," which allows users to navigate and select menus or options by using the Alt key in combination with a designated letter or number.

Question 5

To assign an access key to a text box control, you include the ____ in the Text property of the control's identifying label.

Accepted Answer

To assign an access key to a text box control, you include the ampersand (&) in the Text property of the control's identifying label. When the label is displayed, the character immediately following the ampersand is underlined, indicating the access key.

Question 6

The tab order is determined by the number stored in each control's ____ property.

Accepted Answer

The tab order is determined by the number stored in each control's TabIndex property. This property sets the order in which the controls are focused when the user navigates through them using the Tab key.

Question 7

____ perform their tasks only when the user clicks them.

Accepted Answer

Buttons are designed to perform their tasks only when the user clicks them, acting as a user interface element that triggers specific actions or events.

Question 8

In most interfaces, output items appear in label controls, because users should not be able to edit the value of an output item while an application is running.

Accepted Answer

Label controls are commonly used for output in interfaces because they display text that the user cannot edit, ensuring the output remains consistent and unmodifiable during application runtime.

Question 9

____ case refers to the fact that the uppercase letters appear as "humps" in the name because they are taller than the lowercase letters.

Accepted Answer

Camel case is a naming convention in which the first letter of each word is capitalized and joined together without spaces, making the uppercase letters stand out like the humps on a camel's back.

Question 10

The rules of the Visual Basic language are called its ____.

Accepted Answer

The rules of the Visual Basic language, like any programming language, are referred to as its syntax. Syntax defines the correct combination of symbols that can be used to form a correctly structured program in the language.

Question 11

When using the Tab Order option, you need to set the TabIndex values in numerical order, beginning with the number 1.

Accepted Answer

The TabIndex values do not need to start at 1; they can start at any value, and controls will be accessed in ascending order of their TabIndex values, regardless of the starting number.

Question 12

Every interface needs a control that allows the user to end the application.

Accepted Answer

Every interface needs a control that allows the user to end the application because it is a fundamental principle of user interface design to provide a way for users to exit the application gracefully.

Question 13

You should assign a ____ name to each of the controls in a program, because doing so will help you keep track of the various objects included in the interface.

Accepted Answer

Meaningful names help in identifying the purpose and functionality of controls, making it easier to manage and understand the code.

Question 14

With sentence capitalization, you capitalize the first letter in each word, except for articles, conjunctions, and prepositions that do not occur at either the beginning or the end of the caption.

Accepted Answer

Sentence capitalization involves capitalizing the first letter of the first word in a sentence, proper nouns, and titles, not the first letter of each word except for certain exceptions.

Question 15

When an interface is first created, the TabIndex values reflect the order in which each control was added to the form.

Accepted Answer

The TabIndex values are initially set based on the order in which controls are added to a form, with the first control added having a TabIndex of 0, and each subsequent control receiving a TabIndex value that is one greater than the previous control added.

Question 16

The name of an object must begin with a letter and can contain only letters, numbers, and the underscore character.

Accepted Answer

In most programming languages, the rules for naming objects (variables, functions, etc.) typically require that the name starts with a letter (or an underscore in some languages) and can contain letters, numbers, and underscores but cannot include spaces or other special characters.

Question 17

It is customary to enter identifying labels using ____, which means capitalizing only the first letter in the first word and in any words that are customarily capitalized.

Accepted Answer

Sentence capitalization is the correct term for capitalizing only the first letter in the first word and in any words that are customarily capitalized, similar to the standard practice in writing sentences.

Question 18

When designing an interface for a problem, you should only examine its output items.

Accepted Answer

When designing an interface for a problem, it is important to examine both input and output items to ensure the interface can effectively handle the data it receives and produces the desired outcomes.

Question 19

You can include punctuation characters or spaces in the name of an object.

Accepted Answer

In most programming languages, object names cannot include punctuation characters or spaces; they typically must start with a letter or underscore and can include letters, numbers, and underscores.

Question 20

Actions such as clicking and double-clicking are called commands.

Accepted Answer

Actions such as clicking and double-clicking are typically referred to as actions or user interactions, not commands. Commands often involve issuing instructions to a software or system, usually through a command line interface or through menu selections, rather than through direct manipulation like clicking.
