can you provide an example? I'm not sure if I quite understand what you're saying.

Even if you don't write the iteration, it'll be there. I prefer to write my own stuff so I know what's going on, rather than wondering what's going on behind the scenes.
P.S. You could even write your own indexing using a hierarchy of Dictionaries.

You could have your fifth column be a combination of the numbers. So, the first row would have a "ComboColumn" value of "60,43,33,40". If you have a SQL query fill your DataTable, you could just have it return that "ComboColumn" in addition to the other columns. You could then use datTab.Rows["ComboColumn"].Indexof("60,43,33,40") to find the correct row. However, if that is still too slow, you may want to condider creating a dictionary object to hold the rows with the ComboColumn string as the key. Alternatively, if you are just looking for a single row and you are using SQL, it might be a good idea to just query for that specific row rather than gather data then find it. If you have an appropriate index setup on the table, that should be very fast (also depends on network speed and such).

hmm ComboColumn may be a good idea... I'll give that a shot and see what happens.

I am playing with a small program that sends emails through SMTP server. This is a C# Windows Forms application. The main part of the program looks like this:
using System;
using System.Text;
using System.Windows.Forms;
using System.Net.Mail;
namespace test_email_smtp
{
public partial class send_mail_through_smtp : Form
{
public send_mail_through_smtp()
{
InitializeComponent();
}
private void send_mail_Click(object sender, EventArgs e)
{
SmtpClient client = new SmtpClient(smtp_server.Text);
MailMessage message = new MailMessage(send_from.Text, send_to.Text);
message.Body = mail_body.Text;
message.Subject = mail_subject.Text;
client.Send(message);
message.Dispose();
}
}
}
"send_from", "send_to", "mail_body", "mail_subject", and "smtp_server" are TextBox controls on the Form.
When I ran the program and click the "send" button, and then close the program (by closing the form), the mail is sent IMMEDIATELY.
However, if I click the "send" button and leave the program running (not closing the program), after a minute or so, I will get a message saying "Your mail message was unable to be sent because the connection to your mail server was interrupted. Please open your email client and re-send the message from the Sent Messages folder." This does not happen all the time. I'd say 9 out of 10 times this message was shown. The one time it was not shown, the mail was sent after a long time.
By the way, the message is from "Symantec Email Proxy". When this message was shown, a balloon message was also popped up by the system tray area saying "Scanning message 1 of 1", also from Symantec.
All these problems do not exist if I close the program after I click the "send" button. The mail will be sent immediately. I need the program to keep running after the mail is sent. I can't close the program every time a mail needs to be sent. Any ideas? Thanks!

Trying disabling your antivirus to see if you get the same problem.
If you don't, then it has something to do the the symantec firewall or virus scan.

I have verified that the antivirus software running on my machine was the problem. Your help is appreciated.

The suggestion made by Abhinav may help; if it does not, then:
SmtpClient implements IDisposable so it may be that the email is sent when the client is disposed. This would give the symptoms you describe, at least in terms of the send-when-application-closed problem. Try wraping your section in a using block.
using (SmtpClient client = new SmtpClient(smtp_server.Text))
{
MailMessage message = new MailMessage(send_from.Text, send_to.Text);
message.Body = mail_body.Text;
message.Subject = mail_subject.Text;
client.Send(message);
message.Dispose();
}

Thanks for your reply. I tried that and got the following compile time message:
Error 1 'System.Net.Mail.SmtpClient': type used in a using statement must be implicitly convertible to 'System.IDisposable'
I will do more research on this matter. Thanks!

Hmm. Continuously improving themselves, that is what they are doing. It took them till 4.0 to realize SmtpClient had to implement IDisposable.

After disabling the antivirus program, the original program sends the email immediately when the button is clicked. That indicates that the antivirus was the problem.
I still don't understand why closing the program bypasses the antivirus program's scanning of the email.
Another issue is that it's hard to ask the program's users to turn off their antivirus program to facilitate the healthy running of my program.
My solution to the problem may be to use separate processes for sending emails. I can spawn a small program just to send an email. It terminates by itself right after the mail is sent.
Thank you for your time!

I can see where that might be a problem.

 But if you gotta, you gotta. What kind of virus scanner are we talking?

I have "Symantec AntiVirus" version 10.1.5.500 on my development machine. It's hard to predict what antivirus software will be on my client's machine. I am lucky to see this happen on my machine. Sometimes a fully tested application craps out on client's machines because some other software's interference, making the software developers look bad. I hope that does not happen to me.

I would suggest you try .NET 4.0 and use the new SmtpClient.Dispose() method (directly or through a using statement, doesn't matter). I haven't done so myself yet, but it seems to be a new enhancement by MS, and I expect it to solve your problem.
Of course, you should not disable or replace your AV.

Hi all!
I've tried to create file using File.Open(filePath, FileMode.Create) where filePath contains Unicode symbols. I can see those specific symbols in the explorer but if I try to read folder content via cmd dir I see only "Filename (??????? ???)" where question char replaces desired symbols.
Even more. When I tried to open file from the Explorer I received an error "file does not exist". But opening from cmd with (?????) is OK.
Can anybody help me? Thanks in advance

My advice is to not use unicode characters in paths/filenames.

Find the number of bytes, divide by two.

FTFY.
I don't think they have cut down on the overhead.

I wanna to get this in my C# project.
So Please Help or Give correct solution .
Thanks

Take document as string
Use regex to remove all numbers and punctuation
Split on CRLF for paragraphs, Split on space for word count
That would be my first attempt, and then I would be asking questions on any problems I had. So, maybe you should go and implement that and see if it gets you what you want, then come back and ask specific questions.

Thanks for you reply and solution .
Is it possible for you to give me small example .
