Date Conversion Difference In .net And Sql Server?

Mar 1, 2010

I just realize this difference in date conversion: In SQL server, if you run the code below

declare @dateStr varchar(20)
set @dateStr = '1/1/49'
select cast(@dateStr as smalldatetime)
you will get "2049-01-01 00:00:00"
In .NET taking string with value "1/1/49" and it will turn into
1/1/1949 12:00:00 AM
DateTime dateObj;
dateObj = DateTime.Parse("1/1/49");
Label1.Text = dateObj.ToString();

Can anybody tell me why Microsoft did this and what is the best way to prevent user from entering 2 digits year?

Web Forms :: How To Date Conversion On The Fly

Jul 28, 2010

Im after some advice on date format conversions. I am working on a project that has raddatepicker controls that will take values chosen in the UI and uses them as constraints on a SQL query going back to the database.

My problem lies in the fact that the UI has a sensible date format (dd/mm/yyyy), whereas the database stored dates as "the number of seconds past 00:00:00 01/01/1970". In T-SQL, I can convert using:

[Code]....

I have no idea how to achieve this same conversion in C# so the user can choose a friendly format, but subsequently pass back the database date format.

Conversion From String To Type 'Date' Is Not Valid

Aug 24, 2010

Im receiving a strange error Error Message: Conversion from string "15/08/2010 22:21:35" to type 'Date' is not valid.

I know this is generally down to cultural date formats etc, however the reason this is strange is it just randomly occured twice in the last week, the website has been running since october and nothing has changed,

The error constantly occured until the IIS was reset and recompilled the site, its been running fine since, however im just trying to figure out what could cause such an error to occur.

I've narrowed it down to a line of code which is:

bktime = DReader.Item("Bktime").ToString
bktime = Year(CDate(bktime)) & "-" & fmt(Month(CDate(bktime)), 2) & "-" & fmt(Day(CDate(bktime)), 2)

Has anyone else encountered this randomly occuring and is there anything i can put in place to prevent this in future?
