How to Use the slider control in VB to control controls

Simply write such a piece of code to see if it can achieve the expected results!

1. Add a Slider control to the form, two PictureBox controls, Picture1 and Picture2;
2. Set the picture2 picture attribute in the Properties window to load a background image of the appropriate size. Set the visible attribute of picture2 to false.

The Code is as follows:
Dim x1 As Long, y1 As Long
Dim x2 As Long, y2 As Long
Dim p As Long

Private Sub Form_Load ()
Picture1.ForeColor = vbRed
Slider1.Min = 0
Slider1.max= 100
X1 = 100: y1 = 100
X2 = 500: y2 = 500
Picture1.Line (x1, y1)-(x2, y2), B
P = 0
End Sub

Private Sub Slider1_Scroll ()
Picture1.PaintPicture Picture2.Picture, 0, 0, vbSrcCopy
If Slider1.Value> p Then
X2 = x2 + Slider1.Value
Y2 = y2 + Slider1.Value
Else
X2 = x2-Slider1.Value
Y2 = y2-Slider1.Value
End If
P = Slider1.Value
Picture1.Line (x1, y1)-(x2, y2), B
End Sub
