Date / Time Represented By String Is Not Supported In Calendar System
Aug 9, 2011
I have a application which gets info from an external feed where dates are in the format ddMMM. I'm trying to turn them into full date format so I was using DateTime.ParseExact. Which was correctly working out whether it should be 2011 or 2012 . But it is erroring when trying to parse 29FEB (which should be 29 Feb 2012. I can guess why its erroring. But if that correct behaviour is this documented and is there a better alternative? [code]

I think I might be going mad because I have loads of strings which are being converted into dates and one pesky little one wont go through.
Code:
"Feb 20 10:36"
and
"Dec 11 14:17"
Are acceptable and parse perfectly using Date.Parse() however...
Code:
"Sep 24 11:25"
Does not.
The error I get is:
The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.

I'm using
Days = Dat2.Subtract(Dat1).Days
where
Dat2 = today
Dat1 = installed date
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?

The Now() function in VB.NET returns date and time which is different from the system time that I see on the right-bottom on the notification bar. It is 15 hours slower than the system time. Has anyone ever met this problem? I'm using .NET 2.0.

I am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

How can I convert it to time understood by computer and check if given time is in the past of in the future in comparsion to current time on my computer? I would also like to be able to tell how much difference there is between the time from my data file and the current time. For instance to say "this time was 3 hours and 20 mintues ago".

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)
I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
