Hi
I was testing a quicksort algorithm.
long startTime = DateTime.Now.Ti cks; //ticks before sorting begins
q_sort( 0, mElements.Lengt h-1 );
TimeSpan tp =new TimeSpan((DateT ime.Now.Ticks - startTime)); //difference of
ticks
mSortTime = tp.TotalMillise conds; //sort time in milliseconds
Still, it alwasy returns 0.0
But other algorithms returns a valid value.
However, there is a positive difference between the ticks too.
I can't understand why it is behaving like this. Btw, sorting
works in a different thread.
Any insight?

your code worked fine for me, but i rewrote it for clarity.
static void Main(string[] args) {
DateTime startTime = DateTime.Now; //before sorting begins
Thread.Sleep(10 0); //simulate the sort
DateTime endTime = DateTime.Now; //after the sort
TimeSpan ts = endTime - startTime; //time difference
double mSortTime = ts.Milliseconds ; //sort time in milliseconds
Console.WriteLi ne(mSortTime);
}

Umm, maybe this is either too obvious, or I'm wrong, but at the end of the
OP, KK said the sort runs in a different thread... Maybe
TimeSpan tp =new TimeSpan((DateT ime.Now.Ticks - startTime));
is called before the sorting actually starts in the *other* thread?
Just an idea,

Hi,
I'm using the timespan's Parse method to build my timespan from a
string. here's the line I use :
m_Delay.Parse(RegKey.GetValue("Delay", "01:00:00"))
the value I get from the RegKey is 00:00:30, so it should give a timespan of
30 seconds, but when I do msgbox(m_Delay.ToString), it displays 00:00:00.
Am I doing something wrong?

I'm sure there's an easy solution to this that I am just not thinkin
of. I am trying to get the total minutes between 2 times. It work
fine except when the ending time crosses over midnight. For instance
I am trying to get the total minutes between 11:59 PM and 12:09 AM.
The subtract method on the TimeSpan object returns a crazy negativ
number. I can't seem to find a work around.
Thanks so much in advance!

I want to use TimeSpan to determine the differences between two date to
include time. My input data is in the following format:
12/25/2004 12:23:00 AM or 01/05/2005 11:59:00 PM
How do I get TimeSpan to accept my input?
How do I get the difference between two dates using TimeSpan?
I want to have the results expressed in days, hours, minutes and seconds.

In Visual Studio (Visual Basic) .NET 2002, I noticed that this:

gives a "compile time" error (error in the IDE), saying that the '-'
operator is not defined for the Date datatype. On the other hand,
Dim Elapsed as DateTime = Now + Now
does not give a compile time error but it thinks you're trying to

*should* be really simple, yet I'm struggling with.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
