Help PictureBox Image

[CodeWarrior]

Good day is there any body can help or suggest how to fix my problem.
I'am creating OCR using PictureBox and Timer Control. My problem is
when i run my project the picturebox image moving to the right part.
I want to know if there is any way to display stable my image in picturebox
Here is my code under timer sub tick.

Public Class Form1
    
    Dim igrab As Bitmap = New Bitmap(270, 100)
    Dim icap As Graphics = Graphics.FromImage(igrab)
    
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        icap.CopyFromScreen(New Point(Me.Location.X + PictureBox1.Location.X + 4, Me.Location.Y + PictureBox1.Location.Y + 30), _
                            New Point(0, 0), igrab.Size)
        PictureBox1.Image = igrab
    End Sub
   
End Class
