just check if the distance from your point B to your point A is smaller than or equal to the Radius.
distance between 2 points can be calculated with formula:
pt1 = (x1,y1) pt2 = (x2,y2)
D = sqrt( pow((x2-x1),2) + pow((y2-y1),2) )
It`s been over 10 years since I used these formulas, but I`m quite sure that this is the correct one...

Hi Apurva,
some days back i had also posted a query about sending mails from c#. But that didnt had a great response. and i am not able to device a solution for it till now. Now that this post is also related to emails i would appreciate if you can suggest a solution.
I am using SmtpMail class for sending emails from C# like this -
SmtpServer = <my smtp="" server="" name="">
SmtpMail.Send(frm,to,sub,body)
Here i am setting the server name property with the ip address of my smtp server, which works in outlook. (My outlook is configured for that ip address and works fine). But when the send method is executed it gives an error like cannot create object from CDO sys(something like that). I checked my OS directory for cdosys.dll, and it is present in here. So can you tell what may be the problem?
Is my server name property assignment wrong or something else.

Hi Anant,
I read ur problem i think this can be solution of ur problem.
before using this first u have add reference of System .Web .
bcoz ur using windows application which automatically do noy include
this reference.and write this statement on top.
using System.Web.Mail;
if u still face problem then let me know.
MailMessage objMailMessage;
objMailMessage = new MailMessage();
objMailMessage.From = "Sender ID";
objMailMessage.To = "Reciver ID";
objMailMessage.Subject = "You Subject";
objMailMessage.Body = strHTMLBody;
objMailMessage.BodyFormat = MailFormat.Html;
Thanks & Regards
Nikesh Sahu;)
// Send the Mail Message
SmtpMail.Send( objMailMessage );

Hi,
I want to display some text on a tabpage given that some of the text is linkable. How do I do this?
I tried using both label and linklabel to display them, but the thing is that I don't get any of these label/linklabel text displayed at all except the last linklabel text. What have I done wrong?
int lab_tab_idx = 0;
int linklab_tab_idx = 0;
int y = 0;
foreach (DataRow dr in text.Rows)
{
string text = Convert.ToString(dr[1]);
/* e.g. {hyperlink FANTASTIC PHONICS} is based on national research
which shows that the best outcomes are achieved with
{hyperlink SYSTEMATIC} instruction, using {hyperlink GUIDED
READERS} which are sequential and gently graded. */
string[] newtext = text.Split('{', '}');
int i = 0;
int x = 3;
System.Windows.Forms.Label label = new System.Windows.Forms.Label();
LinkLabel linklabel = new LinkLabel();
while (i < newtext.Length)
{
string tmp = newtext[i];
if (tmp.StartsWith("hyperlink "))
{
tabPage1.Controls.Add(linklabel);
linklabel.AutoSize = true;
linklabel.Location = new System.Drawing.Point(x, y);
linklabel.Name = "linklabel" + linklab_tab_idx;
linklabel.TabIndex = linklab_tab_idx;
linklabel.TabStop = true;
linklabel.Text = tmp.Replace("hyperlink ", "");
x = x + linklabel.Text.Length * 6;
linklab_tab_idx++;
}
else
{
tabPage1.Controls.Add(label);
label.AutoSize = true;
label.Location = new System.Drawing.Point(x, y);
label.Name = "label" + lab_tab_idx;
label.TabIndex = lab_tab_idx;
label.TabStop = true;
label.Text = tmp;
x = x + label.Text.Length * 6;
lab_tab_idx++;
}
i++;
}
y = y + 20;
}
Also, how do I calculate the location of the next label as the text string is dynamic?
Thanks

Your calculations seem right but you are reusing the same Label/LinkLabel again and again instead of creating a new one in each iteration:
while (i < newtext.Length)
{
string tmp = newtext[i];
if (tmp.StartsWith("hyperlink "))
{
LinkLabel linklabel = new LinkLabel();
tabPage1.Controls.Add(linklabel);
linklabel.AutoSize = true;
linklabel.Location = new System.Drawing.Point(x, y);
linklabel.Name = "linklabel" + linklab_tab_idx;
linklabel.TabIndex = linklab_tab_idx;
linklabel.TabStop = true;
linklabel.Text = tmp.Replace("hyperlink ", "");
x = x + linklabel.Text.Length * 6;
linklab_tab_idx++;
}
else
{
Label label = new Label();
tabPage1.Controls.Add(label);
label.AutoSize = true;
label.Location = new System.Drawing.Point(x, y);
label.Name = "label" + lab_tab_idx;
label.TabIndex = lab_tab_idx;
label.TabStop = true;
label.Text = tmp;
x = x + label.Text.Length * 6;
lab_tab_idx++;
}
i++;
}

Thanks for your reply. It works now when I create the label in each iteration.
Some of the labels seem to have overlapped one another and some of them are quite further away from one another. How do I solve this problem?
Is there any other effective way to display text like this? It is quite slow.
Also, why is the text display from bottom up instead of the normal top-to-bottom?
Thanks again.

Thats probably because the length og the characters of the gont you are using isn't always the same. Either use a gont where all characters have a fixed length (like Courier New) or make the following changes:
x = x + linklabel.Width;
x = x + label.Width;
As you have set AutoSize to true this will ensure that the next label is set right next to the previous one. It still might be that there is some space in between but definitely no overlapping.

Great! But the text is displayed from bottom-right back up to top-left. How do I change this display order?

I shortly tested the code and it seems to be in the order I would have suspected. How are you getting the values into the text DataTable? Are you sure its in the correct order in there? If you have a DataGrid where this table is bound to and the grid is somehow sorted or columns are rearranged via column styles this might lead to what you are seeing because the DataTable won't be reordered the way the grid is.
So please describe a bit of the surroundings. Maybe then I can help you.

I guess I have not made it clear enough. When all label text are displayed, they are in correct order. But the last label (which is from the last row of the datatable) is displayed first in the bottom-right corner instead of the first label being displayed first at the top-left corner. Why does this happen?
I tried using flowlayoutpanel but I'm not quite sure how to use this.

Hmm... I don't know. My small test data displayed fine. You could try debugging through each label creation to verifiy that they are created in the correct order... 
|

If you are using .NET Framework 2.0, take a look at the FlowLayoutPanel, which dynamically lays out its contents horizontally or vertically. This could spare you the whole calculation part.

Hi all.
I'm looking for someway that I can set a registration code or license key.
Something in the concept of the app generating a code on their side, they call and give it to us and then we use that code to generate another code on our side. Then they must enter that code provided from us.
Somehow that code must be stored and every time the app is started it must check if the code is still within the valid period.
Any ideas?
Thanx
He who laughs last is a bit on the slow side
