Hi all,
Can any one plse tell me the exact use of serialization? in which scenario
we can use it?

Well, one way that serialisation is really useful is if you want to sell something over a period of weeks. What you do, is run something up to the a point known as the cliff hanger; at this point, you stop and leave people hanging until the next week where you run the next point in the serialisation.

Hi,
When i click on a button a new mail page is open,
and at the body of the mail i put the text that was writen at richtextbox.
my problem is,
when the new mail page is open the text is writen at the same line.
How can i put the text exactly as it writen at the richtextbox.
here is my code:
<br />
string mailTo = "";<br />
string body = richTextBox2.Text;<br />
string subject = textbox1.text;<br />
<br />
string filename = string.Format("mailto:{0}?subject={1}&body={2}", mailTo, subject, body);<br />
<br />
Process myProcess = new Process();<br />
myProcess.StartInfo.FileName = filename;<br />
myProcess.StartInfo.UseShellExecute = true;<br />
myProcess.StartInfo.RedirectStandardOutput = false;<br />
<br />
myProcess.Start();

Try using the System.Net.Mail[^] classes, particularly MailMessage.
MailMessage msg = new MailMessage();
msg.From = "from@from.com";
msg.To = mailTo;
msg.Subject = subject;
msg.Body = body;
msg.IsBodyHtml = true;

 It's a property on the MailMessage class, what do you mean you don't have it?

This is what i get on the line-
msg.BodyFormat = MailFormat.Html;
Cannot implicitly convert type 'string' to 'System.Net.Mail.MailAddress'
'System.Net.Mail.MailMessage' does not contain a definition for 'BodyFormat' and no extension method 'BodyFormat' accepting a first argument of type 'System.Net.Mail.MailMessage' could be found (are you missing a using directive or an assembly reference?)
'MailFormat' does not exist in the current context

My fault the namespace should be System.Net.Mail, not System.Web.Mail and use IsBodyHtml = true

thanks,
can you please tell me how i open this at a new outlook mail?

Hello to all!
I want to implement in C# the RSA algorithm to encrypt and decrypt some data. I've studiet a lot already about this algorithm, but the only thing that I don't understand how to work with very big numbers in C#, even in C++ or C.
The problem is, that in our days, the recommended minimal lenght of the RSA key is 1024 bits. So, the algorithm says:
* n = pq, where p and q are distinct primes.
* phi, φ = (p-1)(q-1)
* e < n such that gcd(e, phi)=1
* d = e-1 mod phi.
* c = me mod n, 1<m<n.
*="" m="cd" mod="" n.
this="" was="" taken="" from="" here:="" http:="" www.di-mgt.com.au="" rsa_alg.html#note1
so,="" the="" keys="" are="" combination:
cpub="(e," n);
cpriv="(d," n);
well,="" ok,="" lets="" say="" for="" example="" that="" we="" generate="" some="" numbers="" and="" obtain="" keys:
public="" key:="" 3,9312243439
private="" 6208033627,9312243439
the="" algorith="" says="" to="" encrypt="" data,="" you="" need="" do:
c="(m" at="" power="" e)="" then="" do="" (mod="" n),="" or="" in="" c#="" like:="" c="(Math.Pow(m," e))="" %="" n;
to="" decrypt="" data:
m="(C" d)="" d))="" n;
so,="" form="" here="" question:
<b="">How to raise a message, lets say the encrypted '10' to our d, that is 6208033627, to obtain the original message?
And after all, our d is only 33 bits length? Tha maximal System.Double value is some 10 at the 308 power.
What I don't understand? What I'm missing? Can anyone explain me this?
I will apreciate your explanation! Thank you in advance!

To do anything like these operations in practically any language in use today you will need to get, or write your own, 'big number library'.
There are several around for the .NET languages and a quick Google will find most of them. Be warned though, some are better than others, you'll have to try them, to find one that suits.
I understand that .NET 4.0 has one built in.

So, the main idea is that really the numbers are raised to a power of 1024 bits? Huh, then this is a problem...

Hi All
I have loaded 3tabes to my application. after the work is done, I wasnt to save it all.
using foreach(is there a better way?) I recreated from my different class objects 3 datatables.
now I have the tables, I think I added them to new ds
DataSet ds= new DataSet();
ds.Tables.Add(emp);
ds.Tables.Add(managers);
ds.Tables.Add(empToManagers);
did I do it write?
no my main question: in my db , I have 3 tables. some of the lines has been changed, deleted or some lines are new. what is the best way to update the db, without checking every line my self, I tried and got lost with the sql.
someone tokd me I can use adapter, but how?
(when I open th data, It is easy to se adapter
public DataSet GetDataSet(string tblName, string sql, DataSet ds)
{
adapter.SelectCommand.CommandText = sql;
adapter.Fill(ds, tblName);
return ds;
}
)
tnx

hi
i have sqlCE DataBase, i have Tdate field (datetime)
i notice that his format is: MM/DD/YYYY
in my C# program i work with date in: DD/MM/YYYY format.
how i can insert to my sqlCE data base my C# format ?
thank's in advance

Simple answer, you don't. The database actually stores the date (and time) as a number, not in any format. You need to do the formatting within your application.

Dates don't have a specific format.
One simply writes the value "as date" to a "date field" in the database. It will be saved in a format-independent way. It's formatted as soon as you look at it. Thus, you should format the data after reading from the database, as soon as you display it.

No. I'm not trying to be cruel to you here, but this is for you to do, and it has to be something that engages your interest and you are capable of completing. I don't know you, so I can't offer any sensible advice on a topic that will keep you motivated when developing, and I don't know what level the BTECH is aimed at, so I can't judge the skill level that will be required.
If I was to suggest something that was too basic, you could end up failing because it's too shallow, and if I suggest something that's too complex, then you won't complete it and you'll fail. Either way, I've done you no favours.
If I were you, I'd look for something that interests you, and that you have sufficient knowledge in already that you don't have to waste unnecessary time researching the topic beforehand.

I know what would be really useful..
An image process application that handles live video stream from any source. Your application will then be able to detect the face of any person in shot and then identify that person by comparing data with a database. This database should contain information stating the security threat of each person and an alert should be made when a person with a high security threat is detected.
Additional, any data detected that is not present in the database should be stored along with a flag that allows a user to go though a list of unidentified people and then choose a further action to take such as providing a name for the person etc.
When you have finished, make sure you create an article on it and submit the source for all to use.
Good Luck!
Life goes very fast. Tomorrow, today is already yesterday.
