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.

Hi Thanks for reply...
I need your suggestion regarding the same...
Is there any algorithm or software available..so that i can buy it
and implement 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

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...

Well then, you must be looking for the Visual Studio Express editions.

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.

How to control over Internet Explorer upload and download events? [modified]

carlecomm21-Sep-09 22:13

i heard about this Technology 'BHO' at once，

but i had no chance to use it. if you really want to control 'Internet explorer', consider using it.

BHO is a simple ATL COM object that Internet Explorer will load each time it runs; in other words, for every instance of Internet Explorer. BHOs run in Internet Explorer's address space and can perform any operation on available objects (windows, modules, and so forth). BHOs instantiate and get destructed with a browser's instance because it is tied to a browser's main window.

If your system has an active desktop enabled, the BHO gets instantiated along with Windows Explorer as well

Hi All,

I want to control over Internet Explorer's upload and download events. Upload and download should happen only for allowed file types. And the file type need to be identified based on the file MIME type. Policy is set for each user. Based on the policy upload and download should happen. Can anybody help me?

Sample Policy:

Allowed URL: www.gmail.com
UPload: jpg,gif,zip,doc
Download : rar,xls,doc

Allowed URL : www.yahoo.com
Upload : .txt
Download : .xls

Solution can be either in VC++ or C#. Any suggestion is appreciated.

There are no events for this.

Again, you'd write a proxy server to control this kind of stuff.

Hi
Could somebody please help me...
I need to create a window that slides from the right border of the screen once a mouse touches it. And well, I have been trying and searching, but didn't manage to.
The only thing I found is this one: AppBar - How to implement a sliding desktop bar with a simple MFC class and a DLL[^]and there is no .net implementation.
