The throw keyword can only be used within a catch block. Throw will simply throw the exception that was caught within the catch block.

if (!File.Exists("test.txt")) {
   throw new FileIOException("File was not found");
}
else {
   ....
}

Sorry to correct you, but throw can also be used outside of a catch block.

try
{
}
catch
{
   throw;
}

So the data is EXACTLY the same (as far as I know).

But the thing is I don't see the milliseconds (if I show the results in the database), so they must be hidden in some way or another.

JelleM wrote:

But can't I use some sort of * to add to the truncated date, so the query doesn't look at the milliseconds or something like that?

this.Size = new Size(1280, 1024);

Have you tried DateTime (And it's static members like DateTime.Parse() etc...?)?
turn it to DateTime and it will be easyer then deviding it by 60 and by 24...
