Working with Forms and Controls in VB.NET Print Dialog Box

The Print Dialog Box in VB.NET is a built-in dialog box that allows users to print a document from an application. It contains a number of controls that can be customized to suit the specific printing needs of the application.

Syntax

To display the Print Dialog Box in VB.NET, use the ShowDialog() method of the PrintDialog class:

Dim printDialogBox As New PrintDialog()
If (printDialogBox.ShowDialog() = DialogResult.OK) Then
    ' Add print code here
End If

Example

In this example, we will create a basic VB.NET application that allows the user to select a printer and specify the number of copies to print. We will create a form with a button that displays the Print Dialog Box when clicked.

Public Class Form1
    Private Sub btnPrint_Click(sender As Object, e As EventArgs) Handles btnPrint.Click
        Dim printDialogBox As New PrintDialog()
        If (printDialogBox.ShowDialog() = DialogResult.OK) Then
            Dim printDocument As New Printing.PrintDocument()
            printDocument.PrinterSettings = printDialogBox.PrinterSettings
            printDocument.PrinterSettings.Copies = numCopies.Value
            printDocument.Print()
        End If
    End Sub
End Class

In this example, we create a new PrintDialog object and call its ShowDialog() method to display the dialog box. If the user selects a printer and clicks the OK button, we create a new PrintDocument object and set its PrinterSettings property to the selected printer. We also set the number of copies to print by accessing the Value property of a NumericUpDown control named numCopies. Finally, we call the Print() method of the PrintDocument object to print the document.

Output

When the user clicks the Print button, the Print Dialog Box will be displayed. If the user selects a printer and clicks the OK button, the document will be sent to the selected printer.
