I have a Session variable in which i have stored one date '22/7/2009'.Now i want to convert value in session to datetime. I tried folowing code:
Session("AppointmentDate") = Request.QueryString("ADate")
Dim s as datetime=Convert.ToDateTime(Session("AppointmentDate"))
But error is showing as 'string is not recognized as a valid datetime'.
Can anybody help me to convert value in Session to date?
Why don't you put the value into the session as a DateTime?
Failing that, use :-
Use :-
DateTime.ParseExact(
myDateString,
"d/M/yyyy",
System.Threading.Thread.CurrentThread.CurrentCulture);
Where myDateString contains your value from Session["AppointmentDate"]
Use DateTime.ParseExact to specify the date format string. I think it'd be something like:
dateValue = Date.ParseExact(dateString, "d", frFR, DateTimeStyles.None)
or
dateValue = Date.ParseExact(dateString, "dd/M/yyyy", enUS, DateTimeStyles.None)
I think you need to store your date as 22/07/2009 so that Convert.ToDateTime() could recognize it.

I've been searching around the net but I only see integer to date. How can I convert a chosen date in radDatePicker to integer? I have tried Convert.ToInt32 but I get an error at runtime
You can try this code
DateTime dt =Convert.ToDateTime(RadDatePicker1.SelectedDate);
string temp = dt.ToShortDateString();
int value;
int.TryParse(temp, out value);
Try this:
DateTime.Now.Ticks
For normal datetime object it works. Means if you could get DateTime value from radDatePicker you may apply .Ticks property to it.
In my SQL database, I have a column formatted as DateTime and when I retrieve data from that column in ASP.NET, I catch it on the Date variable, than pass the value to textbox:
Dim Y As Date = dt.Rows(0)("SCH_DATE")
txtSchedDate.Text = Y.Date.ToString
but when I debug my website, the txtSchedDate.Text still gives me the full DateTime value:
7/17/2013 12:00:00 AM
is it possible to eliminate the time value here and just return the date?
Have you tried using something like
txtSchedDate.Text = Y.Date.ToString("MM/dd/yyyy")
or which ever format you wish to display.
Have a look at
DateTime.ToString Method (String)
Converts the value of the current DateTime object to its equivalent
string representation using the specified format.
Custom Date and Time Format Strings
Standard Date and Time Format Strings
Convert.ToDateTime(dt.Rows(0)("SCH_DATE")).ToString("M/d/yyy")
you can get date by txtSchedDate.Text = Y.Date.ToShortDateString()
Besides answers above, you can try converting it in SQL server
SELECT CONVERT(varchar(15), GETDATE(), 11)
Keep in mind after converting it's VARCHAR(15) instead of DATETIME.
Once you have a Date object, you can get the constituent pieces if you wish as well, like this:
Dim Y As Date = dt.Rows(0)("SCH_DATE")
txtSchedDate.Text = Y.Date.Year & "-" & Y.Date.Month & "-" & Y.Date.Day
Or you can use the custom and standard date and time format strings mentioned by others.
I have a string that holds a value in the format of ddMMyyhhmmss.
Example 240512024707
I need to be able to convert this date to a real .NET Date object.
I am currently using CDate but it seems CDate does not recognize the format, is there any way of specifying the string format to CDate ???
row.Item("NoteDate") = CDate(n.noteText.Substring(0, 12).ToString).ToString("dd/MM/yyyy hh:mm:ss")
You have the string with the date, you know the exact format string - use DateTime.ParseExact (or DateTime.TryParseExact if you wish to avoid the potential exception being thrown):
DateTime.ParseExact("240512024707", "ddMMyyhhmmss", CultureInfo.InvariantCulture)
Just wondering how I can convert the following string into a datetime 111222, at the moment it is telling me that this is not a valid datetime value..
You can use the DateTime.ParseExact method and supply the format your input is in.
Edit - added code:
DateTime dt = DateTime.ParseExact("111222", "yyMMdd", CultureInfo.InvariantCulture);
Console.WriteLine(dt.ToString());

I have datetime field containing '4/1/2009 8:00:00AM'. I want to get '4/1/2009' without the time.
Use the Date property of the datetime field (if you need to do this on the client)
DateTime.Date will give you just the date portion of the datetime if you want to pass it around your application
If you are inside of .NET as it appears that you are based on the tags
dim myDate as DateTime = DateTime.Parse('4/1/2009 8:00:00AM')
dim myDesiredValue as String = myDate.ToShortDateString()
This is C# (yeah - I know you want VB) but given that none of the following uses anything other than DataTime then it should give you want you want...
string foo = "4/1/2009 8:00:00AM";
DateTime bar = DateTime.Parse(foo);
string output = bar.ToString("M/d/yyyy");
Depends on your database server, but in sql server I normally use this in my sql query:
CAST(FLOOR(CAST([MyDateTimeColumn] AS float)) AS datetime)
CONVERT(varchar,mydate,101)
CONVERT(DATE, dateFieldName)
