What replaces the old line/circle/shape control in visual studio 2022 (VB)?

Gary Smith 5 Reputation points

I haven't used Visual Basic for over 20 years, but now I am back to it. What can I do to draw a line or circle? There used to be a shape control. What replaces that?

Also, is there a good replacement for the scroll bars? It seems like the ones in Visual Studio can't change their color.

Any help for an old dog would be appreciated.

    Hi @Gary Smith ,

    You can use a panel control and use the graphics drawing functions in the System.Drawing namespace to achieve.

    Here is an example about drawing a circle.

        Private Sub Panel1_Paint(sender As Object, e As PaintEventArgs) Handles Panel1.Paint
            'Create a Graphics object
            Dim g As Graphics = e.Graphics
            'Create a circular path
            Dim path As New Drawing2D.GraphicsPath()
            path.AddEllipse(0, 0, Panel1.Width - 1, Panel1.Height - 1)
            'Fill the path with color
            g.FillPath(Brushes.Blue, path)
            'Draw a border on the path
            g.DrawPath(Pens.Black, path)
        End Sub

    If you want to modify the color of the ScrollBar, you can customize the appearance of the ScrollBar by extending the System.Windows.Forms.ScrollBar class and overriding the OnPaint method.

    Use the following code to customize the scrollbar, then you can add the custom scrollbar to your form.

    Imports System.Drawing.Drawing2D
    Public Class CustomScrollBar
         Inherits System.Windows.Forms.ScrollBar
         'Override the OnPaint method
         Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
             MyBase. OnPaint(e)
             'Create a Graphics object
             Dim g As Graphics = e. Graphics
             'Set the background color to red
             'Create slider path
             Dim path As New GraphicsPath()
             path.AddRectangle(New Rectangle(0, 0, Me.Width, Me.Height))
             'Set the slider color to yellow
             g. FillPath(Brushes. Yellow, path)
         End Sub
    End Class

    Best Regards.
