Circle Progress Bar Control for VB.NET

Add a new User Control and add these codes in it :

   Dim _Myrr As Integer  
   Public Property rr As Integer  
     Set(value As Integer)  
       _Myrr = value  
     End Set  
     Get  
       Return _Myrr  
     End Get  
   End Property  
   Private Sub DrawProgress(g As Graphics, rect As Rectangle, percentage As Single)  
     'work out the angles for each arc  
     Dim progressAngle = CSng(360 / 100 * percentage)  
     Dim remainderAngle = 360 - progressAngle  
     'create pens to use for the arcs  
     Using progressPen As New Pen(Color.LightSeaGreen, 2), remainderPen As New Pen(Color.LightGray, 2)  
       'set the smoothing to high quality for better output  
       g.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias  
       'draw the blue and white arcs  
       g.DrawArc(progressPen, rect, -90, progressAngle)  
       g.DrawArc(remainderPen, rect, progressAngle - 90, remainderAngle)  
     End Using  
     'draw the text in the centre by working out how big it is and adjusting the co-ordinates accordingly  
     Using fnt As New Font(Me.Font.FontFamily, 14)  
       Dim text As String = percentage.ToString + "%"  
       Dim textSize = g.MeasureString(text, fnt)  
       Dim textPoint As New Point(CInt(rect.Left + (rect.Width / 2) - (textSize.Width / 2)), CInt(rect.Top + (rect.Height / 2) - (textSize.Height / 2)))  
       'now we have all the values draw the text  
       g.DrawString(text, fnt, Brushes.Black, textPoint)  
     End Using  
   End Sub  
   Private Sub UserControl1_Paint(sender As Object, e As PaintEventArgs) Handles Me.Paint  
     DrawProgress(e.Graphics, New Rectangle(5, 5, 60, 60), _Myrr)  
   End Sub  

Don't forget to add these two namespaces :

 Imports System.Drawing  
 Imports System.Windows.Forms  

 Now Build your project and then check your ToolBox you'll see a new Tool

That's our Circle Progress Bar!
Now add our Progress Bar, a Timer and a Button.

Timer1_Tick Code :

     If UPT >= 100 Then  
       UPT = 0  
     Else  
       UPT = UPT + 1  
     End If  
     UserControl11.rr = UPT  
     UserControl11.Invalidate()  
     UserControl11.Update()  
     UserControl11.Refresh()  

Button1_Click Code :

   Timer1.Enabled = True  

Under Public Class add this Integer

   Public UPT As Integer  

That's it, it should work fine now...
