What is the correct format for DateTime.Compare ?

[Guest]

Hi;

What is the correct format for the method DateTime.Compare ?

I can't get this to work -

Dim currDteTime as DateTime = #08/15/2006 02:45:00 PM#

If DateTime.Compare(DateTime.Now, currDteTime) = 0 then
myNextSub()
End If

What am I doing wrong ?

Thanks,

Gordon,

Is it because of the zero before the 8. Instead of #08/15/2006 02:45:00
PM#, try #8/15/2006 02:45:00 PM#. Not sure but I had a problem with
that before.

How are you going to guarantee that DateTime.Now and your curDteTime will
ever be equal?

The datetime.compare is done within a loop. And curDteTime will occur in the
future

 

[Smokey Grindle]

do a parse instead....

dim currDteTime as DateTime = DateTime.Parse("8/15/2006 2:45:00 PM")

its more .NET like then the old VB ## method

I think you should read the Polling For Time article here:

You only gave hours & minutes on your time, datetime.now also includes
seconds, milliseconds & fractions of milliseconds:

currDteTime: 8/15/2006 2:45:00 PM
DateTime.Now: 8/15/2006 5:53:57 PM

Generally its safer to compare times either less or greater; something like:

| If DateTime.Compare(DateTime.Now, currDteTime) <= 0 then
| myNextSub()
| End If

Smokey,

dim currDteTime as DateTime = DateTime.Parse("8/15/2006 2:45:00 PM")

its more .NET like then the old VB ## method

On what is that statement based?

dim currDteTime as DateTime = new DateTime(2006, 8, 14,45,00)

Is in my idea more correct and also in standard ISO globalized format . The
by you used format is only good in the USA and Coca Cola cultures, not even
in English speaking Canada.

Gordon,

In addition to Jay,

Decide what datepart you want to compare.
The current as you have used has in my idea a low hit change because the
datetime structure retuns dates which are a kind of secure in 100th of a
nanosecond.

I would probably do it with an ANDALSO with the date and TimeOfDay member
from DateTime.

I hope this helps,
