vb Code:

Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
        If e.KeyCode = Keys.PrintScreen Then
            MessageBox.Show("hi")
        End If
    End Sub

vb Code:

Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
        If e.KeyCode = Keys.PrintScreen Then
            MessageBox.Show("hi")
