Create a project

Create a Visual Basic application project. The project type comes with all the template files that you need.

Open Visual Studio.
On the start window, select Create a new project.
On the Create a new project window, select the Windows Forms App (.NET Framework) template for Visual Basic. You can refine your search to quickly get to the template you want. For example, enter Windows Forms App in the search box. Next, select Visual Basic from the languages list, and then Windows from the platform list.
In the Configure your new project window, enter HelloWorld as the Project name. Then, select Create. Visual Studio opens your new project.

Open Visual Studio.
On the start window, choose Create a new project.
On the Create a new project window, select the Windows Forms App (.NET Framework) template for Visual Basic. You can refine your search to quickly get to the template you want. For example, enter Windows Forms App in the search box. Next, select Visual Basic from the language list, and then Windows from the platform list.
In the Configure your new project window, enter HelloWorld as the Project name. Then, select Create. Visual Studio opens your new project.

Add a button to the form

After you select your Visual Basic project template and name your file, Visual Studio opens a form for you. A form is a Windows user interface. You create a Hello World application by adding controls to the form.

On the left side of the Visual Studio IDE, select the Toolbox tab. If you don't see it, select View >Toolbox from the menu bar or Ctrl+Alt+X. If you want, select the Pin icon to dock the Toolbox window.
Select the Button control and then drag it onto the form.
In the Appearance section of the Properties window, for Text, type Click this, and then select Enter. If you don't see the Properties window, you can open it from the menu bar. Select View >Properties Window or F4.
In the Design section of the Properties window, change the name from Button1 to btnClickThis, and then select Enter.

Note If you've alphabetized the list in the Properties window, Button1 appears in the (DataBindings) section, instead.

Add a label and code

After you add a button control to create an action, add a label control to send text to.

Screenshot shows a class in the Form1.vs tab where you can add Visual Basic code.

Select the Label control in the Toolbox window, and then drag it onto the form. Place it beneath the Click this button.
In either the Design section or the (DataBindings) section of the Properties window, change the name Label1 to lblHelloWorld, and then press Enter.
In the Form1.vb [Design] window, double-click the Click this button to open the Form1.vb window. Another option is to expand Form1.vb in Solution Explorer. Then select Form1.
In the Form1.vb window, between the Private Sub and End Sub lines, enter lblHelloWorld.Text = "Hello World!" as shown in the following screenshot:

Run the application

Your application is ready to build and run.

Select Start to run the application. Several things happen. In the Visual Studio IDE, the Diagnostics Tools window opens, and an Output window opens. Outside of the IDE, a Form1 dialog box appears. It includes your Click this button and text that says Label1.
Select the Click this button in the Form1 dialog box. Screenshot shows dialog box titled Form 1 that displays the text Hello World!" />The Label1 text changes to Hello World!.
Close the Form1 dialog box to stop running the app.
