Don't Repost, it's very bad form.

Just because you didn't get the answer you were hoping for, it doesn't mean it wrong.

Yes you can get 3rd party software to do this for you.
As Christian Graus said, he has written articles how to perform the image processing.
This is far too complicated a topic to really be dealt with in a forum.

My homework-sense is tingling!

you know of Hough circular transform but clearly lack ability to research, i.e. you were told about it.

Don't you have a tutor for that kind of thing?

I'm more inclined to think he's taken a contract job, and been told to use it, or seen it mentioned in a google search or in a magazine article.

Amusingly, while the wikipedia article has more than enough info that I could write a Hough transform, I don't see how it relates to circle detection.

You're plainly incapable of this task, you should pay someone to write it for you. Although, I did some reading, and I'm not sure how much it would actually help you to count circles.

Hi,

I need to count the no of circles in the image...
Can anyone help ne regarding the same...
Any idea about Hough Transform in .Net?
I am developing the application in .Net...
It is very urgent requirment for me...

Amusingly, it's not urgent to us at all. People who write this sort of message, by and large should not be doing image processing, it involves too much actual work. However, you could read my image processing articles, they have a section on edge detection. and if you have the details of a Hough transform, I'm sure my articles would help anyone who has any idea about programming to write an implimentation. YMMV.

Is there any algorithm or software available..so that i can buy it

There's plenty of image processing libraries you could buy. There's tons of free info on algorithms on the web, far more common than source code. My articles and some SIGRAPH papers should be all you need.

Cross to follow mouse

16-Sep-09 1:10

I have created a control which follows the mouse using MousePosition

However i would actually like the mouse value produced by the control to start at 0 at the top and left sides of my control and finish at 1000. at the bottom and the right sides of the control.

Does anyone know how i can do this?

Thanx in advance

Christian Graus16-Sep-09 1:25

Re: Cross to follow mouse

16-Sep-09 1:25

I'm not sure what you mean, but I think you mean you want to do some basic primary school math to convert the width and height of the control to be a range from 0 to 1000 ?

Thanx for the help.
I have created some code that works now dont know if this is the idea you thought but it functions correctly. Only the painted cross moves the same as the value ill just have to change this and it will be complete.

private int MAX_VALUE = 1000;
private int MIN_VALUE = 0;

private double m_WidthMultiplyNo = 0;
private double m_HeightMultiplyNo = 0;

 public Point Origin
{
   get { return m_origin; }
   set
   {
      m_origin = calculateNewPosition(value);

      if (PositionChanged != null)
      {
         this.PositionChanged();
      }
   }
}

 private Point calculateNewPosition(Point Value)
{
   if (Value.Y < m_position.Y)
   {
      if (Value.X > m_position.X)
      {
         Value.Y -= 1;
         Value.X += 1;
      }
      else if (Value.X < m_position.X)
      {
         Value.Y -= 1;
         Value.X -= 1;
      }
   }
   else if (Value.Y > m_position.Y)
   {
      if (Value.X > m_position.X)
      {
         Value.Y += 1;
         Value.X += 1;
      }
      else if (Value.X < m_position.X)
      {
         Value.Y += 1;
         Value.X -= 1;
      }
   }

   Value.X *= (int)m_WidthMultiplyNo;
   Value.Y *= (int)m_HeightMultiplyNo;

   Value = KeepInsideValue(Value);
   return Value;
}

How to Refresh the CustomTaskPane Control in Outlook

16-Sep-09 1:24

This would involve writing code. What have you written, anything ? It's trivial, you just iterate over the rows, and read the columns. In fact, you could just iterate over the data source, if it's data bound.

Hi,

I am writing an outlook Addin which shows a panel on the explorer window of Outlook.
The Panel shows some details regarding the sender of the Email. My user control "TaskPaneControl" has a panel along with some other controls. My code is as below.

<br />
Microsoft.Office.Tools.CustomTaskPane taskPane;<br />
Microsoft.Office.Interop.Outlook.Application applicationObject;<br />
Outlook.Explorer explorer;<br />
<br />
        private void ThisAddIn_Startup(object sender, System.EventArgs e)<br />
        {<br />
            explorer = this.Application.ActiveExplorer();<br />
<br />
            explorer.SelectionChange += new ExplorerEvents_10_SelectionChangeEventHandler(activeExplorer_SelectionChange);<br />
        }<br />
<br />
        void activeExplorer_SelectionChange()<br />
        {           <br />
<br />
            if (taskPane == null)<br />
            {<br />
                taskPane = Globals.ThisAddIn.CustomTaskPanes.Add(<br />
                  new TaskPaneControl(), "Sender Details", explorer);<br />
                taskPane.Visible = true;<br />
                taskPane.Width = 245;<br />
                return;<br />
            }<br />
<br />
            if (taskPane != null)<br />
            {<br />
                Microsoft.Office.Interop.Outlook.Selection selection = explorer.Selection;<br />
<br />
                if (selection.Count == 1 && selection[1] is      Microsoft.Office.Interop.Outlook.MailItem)<br />
                {<br />
                    Microsoft.Office.Interop.Outlook.MailItem mailitem = (Microsoft.Office.Interop.Outlook.MailItem)selection[1];<br />
<br />
                    TaskPaneControl ct = new TaskPaneControl();<br />
<br />
                    ct.ShowEmailDetails(mailitem);  <br />
                }            <br />
            }<br />
        }

The problem here is, on change of Email in the inbox, activeExplorer_SelectionChange method gets executed but the taskpane will not be refreshed.
Please let me know how to refresh the Task pane Contol.

Thanks in advance.

Hi All,

I want to calculate the bandwidth used by Internet explorer for each domain(google,yahoo,aol,etc). The number of bytes received and sent for each domain need to be calculated. Solutions can be c# as well as in VC++.
Thanks in Advance...

This would require that you write a proxy server to track this kind of information. You'd point the browser at the proxy and the proxy would retrieve the pages for the browser. This gives you the capability to track every byte that goes through the proxy.
