Answer 1

Hi,

Do you want to change the size of OvalShape2 with Scroll TrackBar1.Value?

Public Class Form1
    Dim ph As Integer
    Dim pw As Integer
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        PictureBox1.BackColor = Color.Black
        ph = PictureBox1.Size.Height
        pw = PictureBox1.Size.Width
        TrackBar1.Minimum = 1
        TrackBar1.Maximum = 4
    End Sub
    Private Sub TrackBar1_Scroll(sender As Object, e As EventArgs) Handles TrackBar1.Scroll
        PictureBox1.Width = pw * TrackBar1.Value
        PictureBox1.Height = ph * TrackBar1.Value
    End Sub
End Class

Best Regards,

Alex

Answer 2

Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll
        TrackBar1.Value = OvalShape2.Size

End Sub

When i type this code i got the error

OvalShape2.Size is a Struct in the System.Drawing namespace that consists of
an ordered pair of integers representing the Height and Width. The 
TrackBar Value property is a single Int32. You can't assign a struct to an integer.
