#APLIKASI VB NET 2010 MENGGUNAKAN MS ACCESS CODE#
It's much more likely that a C# programmer will understand your code if it's written as shown above than if you cram it into a module and let the compiler handle everything. And for what it's worth, I do not recommend this as a "best practice" because I feel that it tends towards obscurity and clean object-oriented code/design. I think that as a programmer, it's important to understand what's going on and what exactly your tools are doing for you, even if you decide to use them. Even if you decide to go this route, it's worth understanding what is happening behind the scenes in an object-oriented language like VB.NET. The IDE allows you to call members from modules without fully-qualifying or importing a reference to them. In VB.NET, which offers modules for backward-compatibility purposes with previous versions of VB, a Module is simply a sealed static class (or, in VB.NET terms, Shared NotInheritable Class). Note that this is exactly the same thing that the compiler is doing for you behind-the-scenes when you declare your global variables in a Module, rather than a Class. Then, you could simply reference the variables by their name. If the practice of fully-qualifying your variables horrifies or upsets you for whatever reason, you can always import the class that contains your global variable declarations (here, GlobalVariables) at the top of each code file (or even at the project level, in the project's Properties window). You can't simply access the variable by typing UserName outside of the class in which it is defined-you must also specify the name of the class in which it is defined. MessageBox.Show("Hello, " & GlobalVariables.UserName) Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load In this sense, they are not the type of global variables with which you may be familiar from other languages, because they are still associated with some particular class.įor example, if you want to display a message box in your form's code with the user's name, you'll have to do something like this: Public Class Form1: Inherits Form However, you'll need to fully-qualify all references to those variables anywhere you want to use them in your code. Public Shared UserName As String = "Tim Johnson"
What you can do (as some of the other answers have suggested) is declare everything that you want to treat as a global variable as static variables instead within one particular class: Public Class GlobalVariables Informatika, 2008.There is no way to declare global variables as you're probably imagining them in VB.NET.
