Hello,
Since I am learning C# now, I might have a simple question, I know my
datarow dr[myDate] keeps datatime and I need to compare it if it is current
date, if not how many days ago? How should I compare date and find how many
day difference?
Thanks,
Jim.

Assuming your date in the row is XXX as a DateTime object:
TimeSpan ts = DateTime.Now - XXX;
Now you can look at ts properties such as TotalMinutes, etc.

Hi Jim,
You would use the methods of the DateTime object: http://msdn.microsoft.com/library/de...classtopic.asp

Thanks for the reply.
DateTime sDate=System.Co nvert.ToDateTim e(dr["myDate"]);
TimeSpan ts = DateTime.Now - sDate;
int tHours=ts.Hours ;
int tDays=ts.Days;
This is working fine to see discrepancy in hours. Now I only need to compare
date part of DateTime for both dr["myDate"] and DateTime.Now. how should I do
this?
Thanks,
Jim.

DateTime sDate=System.Co nvert.ToDateTim e(dr["myDateTime "]);
if (sDate.Date < DateTime.Now.Da te)
{
debug= "Warning: old date!";
}
do you see any problem with this comparision, it seems it is working?
Thanks,
Jim.

Jim:
DateTime.Now gives you the current date and time, and DateTime has a
subtraction method defined (which returns a TimeSpan, and a TimeSpan
has a Days property). There are some examples in the docs: http://msdn.microsoft.com/library/de...tracttopic.asp

Hello,
I am comparing two date values, one from a database and one that has
been converted from a hard-coded string into an actual Date type. So
far so good. The problem I'm having is that one of the values comes
from the database, and for existing values it works fine, but if the
date doesn't exist (which will always be the condition when the user
first enters into the form) I am adding logic to my javascript like: if

Hi,
I have a wrong result when testing today against a date fetched from a table
in excel.
The value in excel is: 14/12/2006 (european format).
When today is after that value in excel, the message "time is over" must
appear, otherwise nothing.
My problem is that the message appear already when today = that value.
Any idea why?

Hi,
I have designed an employee portal. The moment the user logs in and logs out the current datetime will be stored.
Before the user logs out I should ensure whether he/she has entered the work done form for that day.
I wrote
select count(*) from workdone where work_date_time=getdate()
If there are any rows that means he/she has filled up the form else not filled.
But the query is comparing the date as well as time.

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.
