    Create custom line in vb.net

    Is there a way to create custom lines in vb.net?
    I cannot find a way to do so and it would be really helpful if any of you could help me.
    Thank you.

    Where do you want to draw the line? On your form? If so, you just use the formís paint event. The eventargs has a graphics object. You use the graphics object drawline method...

    yes you can, as said by .paul. , you draw in the pain event : here is an example with the form1 paint event from https://www.worldbestlearningcenter....wing-lines.htm

    it works with all paint event of controls (picturebox, button, etc)

    Code:
    Private  Sub Form1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint      
                                   
        'Create point objects      
        Dim pt As New Point(50, 50)      
        Dim pt1 As New Point(300, 50)      
        Dim pt2 As New Point(200, 70)      
        Dim pt3 As New Point(50, 170)      
        Dim pt4 As New Point(300, 170)      
        Dim pt5 As New Point(200, 70)      
    
        'Array of points      
        Dim pArra() As Point = {pt2, pt3, pt4, pt5}      
    
        'Draw a line      
        e.Graphics.DrawLine(Pens.Orange, pt, pt1)      
    
        'Draw multiple lines      
        e.Graphics.DrawLines(Pens.Blue, pArra)      
                 
    End Sub

    Also, if you want to be interacting with the line, look into the GraphicsPath object. You can draw lines with that, and be better able to deal with mouse events.
