- Are true and false keywords?
-
True
-
False
AI Explanation
To answer this question, we need to understand the concept of keywords in programming languages.
Option A) True - This option is incorrect because "True" is not a keyword in most programming languages. While some programming languages may have a keyword called "True" to represent a boolean value of true, it is not universally recognized as a keyword.
Option B) False - This option is correct because "False" is not a keyword in programming languages. In most programming languages, the keywords for representing boolean values are typically "true" and "false" (in lowercase).
The correct answer is B) False.

How do you enable Strict Type Checking in VB.NET
-
With OPTION STRICT ON keyword
-
With OPTION EXPICIT Keyword
-
With OPTION STRICT OFF keyword
-
All the above
To enable Strict Type Checking in VB.NET, you need to use the "Option Strict On" keyword. This will enforce data type checking for all variables, parameters, and return types in your code.
Option Explicit, on the other hand, enforces explicit declaration of all variables in your code.
Option Strict Off disables strict type checking and allows automatic type conversions, making it easier to write code but potentially less safe.
Therefore, the correct answer is:
The Answer is: A. With OPTION STRICT ON keyword
How do you add Web Methods in VB.Net
-
Add keyword to Method signature
-
Add [WebMethod] on top of the Method Signature
-
Add {WebMethod} on top of the Method Signature
-
None of the Above
AI Explanation
To add web methods in VB.Net, you need to add the [WebMethod] attribute on top of the method signature. This attribute is used to indicate that the method can be invoked from a web service.
Let's go through each option to understand why it is correct or incorrect:
Option A) Add keyword to Method signature - This option is incorrect because there is no specific keyword to add to the method signature to indicate a web method in VB.Net.
Option B) Add [WebMethod] on top of the Method Signature - This option is correct because adding the [WebMethod] attribute on top of the method signature is the correct way to indicate that the method is a web method in VB.Net.
Option C) Add {WebMethod} on top of the Method Signature - This option is incorrect because the correct syntax for adding attributes in VB.Net is to use square brackets ([ ]), not curly brackets ({ }).
Option D) None of the Above - This option is incorrect because option B, which suggests adding [WebMethod] on top of the method signature, is the correct way to add web methods in VB.Net.
Therefore, the correct answer is B) Add [WebMethod] on top of the Method Signature.
How do you create a Read only Property in VB.NET
-
Using Only Get..EndGet with in property definition
-
Using Only Set..EndSet with in property definition
-
Using both Get and Set
-
None of these
AI Explanation
To create a read-only property in VB.NET, you can use the "Only Get..End Get" syntax within the property definition.
Option A) Using Only Get..End Get within the property definition - This option is correct. By using the "Only Get..End Get" syntax, you can define a property with a getter method only, making it read-only. This means that the property can be accessed and retrieved but cannot be modified or set.
Option B) Using Only Set..End Set within the property definition - This option is incorrect. The "Only Set..End Set" syntax is not valid in VB.NET and cannot be used to create a read-only property.
Option C) Using both Get and Set - This option is incorrect. If a property has both a getter and a setter method, it is a read-write property, not a read-only property.
Option D) None of these - This option is incorrect. The correct option is A, which explains how to create a read-only property in VB.NET.
The correct answer is A) Using Only Get..End Get within the property definition. This option is correct because it demonstrates the correct syntax to create a read-only property in VB.NET.
