Date Literals That Include Milliseconds

[Nathan Sokalski]

I have a control uses the date and time, including milliseconds. I want to
be able to enter this information as an attribute in the *.aspx page.
Because all attributes are entered as strings in the *.aspx page, I need a
recognizable date/time string that includes the date and time, including
milliseconds. Can somebody tell me the best format to do this in? Thanks.
(NOTE: The date/time data is coming from a databound field from an SQL
Server database.)

Nathan,

Because there are so many processes bussy mostly, is the windows operating
system probably not that accurate that you can get the real time in
milliseconds.

However the datetime.millisecond gives something back what reaches that the
most, but that is not in a literal, so just appending the toString with the
& will probably be the best.

DateTime dtmDateTime = <however you get your datetime variable>;
string strDateTime = dtmDateTime.ToString("dd MMM yyyy HH:mm:ss:fff");

You have me confused; the examples you give are in the codebehind, I am
looking for a string that can be assigned to a datetime attribute that
includes milliseconds. For example:

<cc1:TimePicker id="timepkr" runat="server" SelectedTime="datetime string
with milliseconds">

SelectedTime is a property of type DateTime, so I need to know how to format
the string I assign to it. The examples you gave assign a String that you
didn't show me to a DateTime and assign a DateTime to a String. You did not
tell me the piece of information I am looking for: What format is the string
in when you assign it to the DateTime? Thanks.

SelectedTime is a property of type DateTime

Er, no it isn't - the following MSDN page lists the properties of a DateTime
variable:
http://msdn2.microsoft.com/en-us/library/system.datetime_properties(VS.80).aspx

There is no SelectedTime property...

You said: "(NOTE: The date/time data is coming from a databound field from
an SQL Server database.)"

The code I gave you will accept a DateTime variable (which could be fetched
from a data object) and will then cast it to a string which includes
milliseconds...

If that's not what you require, then please explain in more detail...

I'm sorry, I think I was unclear in the way I phrased that statement. When I
said "SelectedTime is a property of type DateTime", I meant that my Control
has a property named SelectedTime that is a DateTime, like the following:

Public Property SelectedTime() As DateTime

But back to my original question, are you saying that if I do something
like:

<cc1:TimePicker id="timepkr" runat="server" SelectedTime='<%#
DataBinder.Eval(Container.DataItem,"myfield") %>'>

It will assign the entire date & time including milliseconds from the
database to my SelectedTime property? The reason this concerned me is
because the single quotes around the databinding expression made me think
the value from the database was converted to a String before being assigned
to the property. Is this true, or will the exact value from the database be
assigned to the property without being converted to a string first? Thanks.

What happened when you tried it...?

I believe you can use:

myDateTime.ToString("M/d/yyyy HH:mm:ss:fff")

To print a date something like:

8/27/2007 06:37:13:0257

myDateTime.ToString("M/d/yyyy HH:mm:ss:fff")

Sorry Mark - didn't realize I repeated you. Apparently, this
originally multiposted thread turned into a crossposted thread. All
your earlier posts are only on the
microsoft.public.dotnet.framework.aspnet newsgroup and not the
microsoft.public.dotnet.languages.vb newsgroup from which I am
posting.

Ah right - the OP does have a habit of cross-posting, which I usually
correct if I remember...

X-posted deliberately to microsoft.public.dotnet.languages.vb

Did anybody read the Subject of this thread? It says Date LITERALS, not Date
Formatting. This means I want a Date String that already is a String that I
can assign to a Date Object. My reason for needing this is that I need to
declaratively assign a date to a Control Property in the *.aspx file using
Attributes. Any ideas? Thanks.

string strDateLiteral = "29 Aug 2007 15:59:13:123";
DateTime dtmDate = DateTime.ParseExact(strDateLiteral, "dd MMM yyyy

Seth's first rule of newsgroups: Act like an ***hole - receive no more
help.

With that said, I consider this a warning and try to help you again.

This means I want a Date String that already is a String that I
can assign to a Date Object.

I don't see the problem - you can assign the string for the Control's
property like this:

<uc1ateUC ID="theDateUC" runat="server" TheDateTime='8/29/2007
09:01:52.257' />

In my usercontrol I created the property looks like:

public DateTime TheDateTime {
get {
return DateTime.Parse(this.dateTimeLiteral.Text);
}
set {
this.dateTimeLiteral.Text = value.ToString("M/d/yyyy
HH:mm:ss:fff");
}
}

And everything showed up in my literal control just fine.

Thanks,

Seth Rowe

The OP is well-known for that - he's a recent graduate who firmly believes
that the world owes him a living, and that these newsgroups are his own
private helpdesk...

Maybe he'll grow up one day...

Thanks for the warning Mark, I'd go ahead and killfile him now if I
didn't insist on using google groups as my newsreader.

Nathan,

Maybe you can next time write a message like your subject, putting "Wood" in
your subject and start than to write about "Bush" does not give good
information.

This is what you wrote.
milliseconds.

This does not mean (probably beside in your mind)

Although it is for me completely not to understand what you want.

A DateTime literal is fixed in one format, which is based on the USA time
and almost never usable in the rest of the world or by internet sites which
are not only for the USA (In fact can that be all COM, ORG, NET, TV and more
of those sites). Therefore it probably even for most not recognisable what
you want in these very much international newsgroups.

Outside the USA probably nobody uses them.
