i m doin device application
the problem is wih socket
my code was
clientsocket = new TcpClient(ip,2000);
clientsocket.ReceiveTimeout=10000;
this code gives an exception "option is not supported or something like that"
but this workd fine in windows application
so i wrote
clientsocket = new TcpClient(ip,2000);
this line raises exception
i m receiving exception
"An operation was attempted on something that is not a socket" after sometime or after a sequence of clicks
i think the problem is with socket timeout
if so how can i increase the socket time out
can any one help

Hi,
I suggest you read the remarks in the MSDN document.[^] which is always a good thing to do (1) before using something and (2) when having problems.

Out email provider has SMTP authentication set to require "Log on to incoming mail server before sending"
In outlook, I configure this option in the Outgoing Server Settings. Its easy.
However, I can find no way of doing this programatically with System.Net.Mail. Or at least no config settings that give a clue.
If I set outlook to use the same credentials as the incoming server then it fails. i.e. I can't just provide the username and password as it won't work.
Any clues?
regards
James

you can do it like this:
<system.net>
<mailSettings>
<smtp from="validname@mydomain.com">
<network host="mail.mydomain.com" password="" userName="validname@mydomain.com"/>
</smtp>
</mailSettings>
</system.net>

}
I define a column by inheritting the DataGridViewColumn, and add a property for this column, but in the design-mode when I change the value of this property , the value can not be saved, the codes as above. how to solve this issue? Thanks in advance!

Don't repost - it displays an ignorance of forum use
What the hell do you want if the link d@nish supplied is not an answer to your question.

The link d@nish sent you was probably the ONLY straight forward approach to doing what you want. I also was looking something like this and I have already implemented the feature with no issues. What's stopping you?

Hi.
I need to calculate the difference between two date and time fields
I Am Try blow coding but give error
"String was not recognized as a valid DateTime"
InitializeComponent();
{
timer.Tick += new EventHandler(timer1_Tick);
timer.Interval = (1000) * (1);
timer.Enabled = true;
timer.Start();
}
private void Form1_Load(object sender, EventArgs e)
{
label7.Text = DateTime.Now.ToShortTimeString();
DateTime dt1 = DateTime.ParseExact(label6.Text, "hh:mm:ss", new DateTimeFormatInfo());
DateTime dt2 = DateTime.ParseExact(label7.Text, "hh:mm:ss", new DateTimeFormatInfo());
TimeSpan ts1 = dt1.Subtract(dt2);
textBox1.Text = ts1.ToString();
}
private void timer1_Tick(object sender, EventArgs e)
{
label6.Text = DateTime.Now.ToShortTimeString();
label6.Text = DateTime.Now.ToString("hh:mm:ss");
}

On my PC, DateTime.Now.ToShortTimeString() shows the date as 11:42 AM. If you have something similar, it will fail when you parse it as hh:mm:ss.
What happens when you debug it and watch the values? Do the two labels really show the date in hh:mm:ss format? Either change the format string, or use DateTime.Now when you do the subtraction.

Values in label6 is like 11:18:17 and Values of label7 is 11:18:17, the value of label7 is constant.
|
|
|
|

DateTime dt1 = DateTime.ParseExact("11:15:00", "hh:mm:ss", new DateTimeFormatInfo());
DateTime dt2 = DateTime.ParseExact("11:20:00", "hh:mm:ss", new DateTimeFormatInfo());
TimeSpan ts1 = dt1.Subtract(dt2);
Console.WriteLine(ts1.ToString());
Works for me.
Do you get the error when you create dt1 or dt2?

Hi,
what is all this???
have you read the DataTimeFormatInfo documentation[^]?
are you aware that ToShortTimeString() uses the regional settings of your PC?
and new DateTimeFormatInfo() does not?
and why store text twice in label6?
and why parse text from label7 as you know quite well what is in there?
and why going for a negative time span?

Hi,
so you choose to ignore my 7 questions? and want something from me? take this:
private DateTime started;
public Form1() {
InitializeComponent();
started=DateTime.Now;
timer.Tick += new EventHandler(timer1_Tick);
timer.Interval = (1000) * (1);
timer.Start();
}
private void timer1_Tick(object sender, EventArgs e) {
DateTime now=DateTime.Now;
label6.Text = "It is now "+now.ToString("HH:mm:ss");
double seconds=now.Subtract(started).TotalSeconds;
label7.Text = "which is "+seconds+" seconds since this form started.";
}

Luc, I appreciate your intent, but spoonfeeding creates rather than solves problems.

I agree, and I seldom do spoon feed. I usually provide pointers, and/or my go study a book[^] advice.
In this case, there was too much wrong IMO, so I decided to provide a reasonable starting point.
