5. VB.Net Overriding (Overridable, Overrides)

In VB.Net, you specify a virtual method with the Overridable keyword in a parent class and extend (or replace) it in a descendant class using the Overrides keyword.

Use the base keyword in the descendant method to execute the code in the parent method, i.e. base.SomeMethod().

6. VB.Net Pointers (None)

VB.Net doesn't support pointers. The closest it comes is IntPtr which you use to get pointer handles on windows, files, etc.

C# does have better support for pointers and C++/CLI has extensive support. One solution when it's really needed in VB.Net is to code in C# or C++/CLI and add it to your project.

However, VB.Net does support references.

7. VB.Net Self Keyword (Me)

To refer to the current instance of a class or structure, use the Me keyword. Me provides a way to refer to the specific instance in which the code is currently executing. It is particularly useful for passing information about the currently executing instance.

The Me keyword is also used as a modifier of the first parameter of an extension method.

You cannot use Me with static method functions because static methods do not belong to an object instance. If you try, you'll get an error.

9. VB.Net Deployment Overview

VB.Net projects require the .Net framework and any additional dependencies you've added such as Crystal Reports.

In Visual Studio.Net, you can create a Setup and Deployment project by using any of the templates available on the New Project dialog (Other Project Types).

In addition, VB.Net projects also support ClickOnce which brings the ease of Web deployment to Windows Forms and console applications. To get started, right click on your solution in the Solution Explorer, click Properties then select the Security tab. 

In addition, you can use any of the many free and commercially available installation packages.

4. VB.Net Constants (Const kPI Double = 3.1459)

In VB.Net, you define constants with the Const keyword.

All constants are part of a class (no global constants) but you can make a constant public and have access to it using ClassName.ConstantName so long as you have added the class to the project. This works even without creating the class as if the public constants were static, but you cannot use the Shared keyword.

Constants must be of an integral type (sbyte, byte, short, ushort, int, uint, long, ulong, char, float, double, decimal, bool, or string), an enumeration, or a reference to null.

6. VB.Net Overloading (Overloads, or implicit)

VB.Net supports both method and operator overloading.

For method overloading, you either use implicit overloading (no special syntax like C#) or use the Overloads keyword. If you use the Overloads keyword, all overloaded methods with the same name in the same class must include the Overloads keyword.

7. VB.Net Member Field

In VB.Net you can set the visibility of a member field to any visibility: private, protected, public, friend or protected friend.

You can intialize a member field with a default when declared. If you set the member field value in your constructor, it will override the default value.

Finally, you can use the Shared modifier (no instance required) and ReadOnly modifier (similar to a constant).
