  3. Add two Buttons to your form.
    • Ideally, place the two Buttons near the RichTextBox.
    • Again, you can add Buttons to your form by double-clicking or dragging onto the form.
  4. Name the Buttons "Print" and "Print Preview".
    • You can change the text for the buttons in the properties box.
  5. Add the controls: "Print Document" and "PrintPreviewDialog" to your form.
    • These will not be visible on the form as they perform in the background.
  6. Click on PrintPreviewDialog and change the "Document" to "PrintDocument1".
    • You can change this in the properties box after clicking on PrintPreviewDialog.

The Code

  1. Double-click on your "Print Preview" button.
    • This will bring up the page for coding.
    • A Private Sub has already been created and awaiting code to tell it what to do when the Print Preview button is clicked.
    • Add the following code into the Private Sub: PrintPreviewDialog1.ShowDialog()
  2. Go back to the form and double-click on your "Print" button.
    • You will be taken back to the page for coding.
    • In the Private Sub that has been created, add the following code: PrintDocument1.Print()
  3. Go back to the form and double-click on "PrintDocument1" located underneath the form.
    • You will be taken back to the page for coding.
    • A Private Sub will be created called "PrintDocument1_PrintPage". Place the following code into the Sub: Dim font1 As New Font("arial", 16, FontStyle.Regular) e.Graphics.DrawString(RichTextBox1.Text, font1, Brushes.Black, 100, 100)
