Working with Forms and Controls in VB.NET: TextBox Control

The TextBox control in VB.NET is a basic control used to display and accept inputted text from the user. It can be used to display text, accept user input, and provide validation for that input.

Syntax

To add a TextBox control to a form in VB.NET, simply drag and drop the control from the "Toolbox" onto the form. The following is the basic syntax to create a TextBox control programmatically:

Dim txtBox As New TextBox
txtBox.Location = New Point(x, y)
txtBox.Size = New Size(w, h)
Me.Controls.Add(txtBox)

Here, x and y are the coordinates for the location of the TextBox control, and w and h are the width and height, respectively.

Example

The following example shows how to add a TextBox control to a form in VB.NET:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim txtBox As New TextBox
    txtBox.Location = New Point(50, 50)
    txtBox.Size = New Size(200, 20)
    Me.Controls.Add(txtBox)
End Sub

Output

The above code will display a TextBox control on a VB.NET form.

Explanation

In the above example, we have created a TextBox control programmatically and added it to a form using the Me.Controls.Add method. We have also set the location and size of the TextBox control using the Location and Size properties, respectively.
