Working with Forms and Controls in VB.NET Form Controls

Forms and controls are two important components of VB.NET user interface programming. In this page, we will discuss how to work with forms and controls in VB.NET form controls.

Syntax

The basic syntax for working with forms and controls in VB.NET is as follows:

• To create a new form, use the New keyword followed by the name of the form class. For example, to create a new Form1, use Dim form1 As New Form1().
• To add a control to a form, first select the Toolbox pane in Visual Studio. Then, drag the control that you want from the Toolbox pane onto the form.
• To modify the properties of a control, select the control in the form designer. Then, go to the Properties pane, and modify the properties as needed.

Example

Let's take a look at an example of how to create a simple VB.NET form with a button control.

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        MessageBox.Show("Hello, World!")
    End Sub
End Class

Output

When you run the above code, a new form will appear on the screen with a button labeled "Button1". Clicking on the button will display a message box saying "Hello, World!".

Explanation

The above code creates a new VB.NET form called Form1. The form contains a Button1 control. When the button is clicked, an event is raised, which handles the event by displaying a message box with the message "Hello, World!".

Use

Forms and controls are essential components of VB.NET user interface programming. You can use forms to create a visually appealing and easy-to-use interface for your application. Controls allow you to add buttons, labels, textboxes, and other user interface elements to your form.

Important Points

• Forms are created using the New keyword followed by the name of the form class.
• Controls are added to a form by dragging the control from the Toolbox pane onto the form.
• The properties of a control can be modified using the Properties pane in the form designer.
