use some database to track the user whether he voted or not corresponding to the specific item.
You can also save the IPaddress to prevent more than one post from the same IP.

There's no reasonable way of doing this without expecting people to log into your site before they are allowed to vote.

My web server is not my country, so server's time and my country time is
different.
So code runs on server,
for example when I run DateTime.Now() function
it returns server time but I want to get my local time.
Is there a way to do that?

Perhaps you can convert a DateTime to UTC using the DateTime.ToUniversalTime method

You asked this the other day and you were given at least one useful answer. Instead of trying it, or asking about it, you just post the same question again. Did you try what was suggested ?

i want to store null in database in field having datetime datatype
but i am not able to do it
i tried this
convert.toDateTime(null)
i am get this error
SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

OK - this means that your DB will only accept a date. You should change the DB so it will take null, or you should sanitise your input. Either way, Convert.ToDateTime(null) is a nonsense. You should pass in DbNull.Value, or null, whichever works, to store null.

Do you mean what I said here, or in the other thread you started as a different user ?
If your DB takes null, then you won't get an error if you insert null. But Convert.ToDAteTime(null) is a nonsense, that won't work.
What did you try, and what happened ?

This is ridiculous. Why pass an object and not a DateTime? ? Then you can use .HasValue, and generally write nice code.
Have you set a breakpoint to see which code executes ? Have you tried DbNull.Value ? I wonder if SqlDateTime is a type for SQL Server only ?

i did what u said
if (Date_Start == null){

}

i am doing this
DateTime CompletionDate;
if (txtCompletionDate.Text != "")
{
CompletionDate = Convert.ToDateTime(txtCompletionDate.Text);
}
else
{
CompletionDate = null;
}
and passing this CompletionDate to Store procedure
but i am getting error
cannot convert null to datetime

use it before pass to DB
if (CompletionDate == null)
{ cmd.Parameters.AddWithValue("@CompletionDate",System.Data.SqlTypes.SqlDateTime.Null);
}
else
{
cmd.Parameters.AddWithValue("@CompletionDate", CompletionDate);
}
and also in DB "CompletionDate" field shulid allow null

Oh, you were answering, not asking. The code you posted is still messy, even if SqlDateTime.Null works.

in DB completiondate allows null
but it still gives same error

How do you know it allows null ? In any case, your error is not that null is not allowed, but that the date object is broken. I think you need to make your code typesafe, walk through with the debugger and see what date is passed in. You also need to fix your code where it is prone to breaking.

This is messy. What if the text entered cannot be converted ? This code is fragile and not production quality, on many levels.
I need to see the code that throws that error, in order to comment on it.

i am get error in below code

}
db.ExecuteNonQuery(dbcommand);
return true;

Why are you still passing this as an object ? In any case, if this is passing DBNull.Value, and the procedure fails, then your database doesn't support null. That's really about it. Have you tried running the proc directly against the database ? What does the proc look like ?
I can't help but feel that if you made this code typesafe, it might well work. You're not passing a datetime, you're passing an INullable<DateTime> and I can't help but wonder if that makes a difference, when all you tell the compiler is that it's an object.

Copy the files onto the server. Make sure the server has ASP.NET installed. Point IIS to your site.
