I followed suggestion from vb.net convert string to date . But, it did not work.
the code is as follows:
Dim Dt As DateTime
If DateTime.TryParse("Thu, 09 Dec 2010 16:03:24 EST", Globalization.CultureInfo.InvariantCulture, Globalization.DateTimeStyles.None, Dt) Then
MessageBox.Show(Dt)
End If
Can anyone solve this for me? I need to have date populated in the format of "yyyy-mm-dd hh24-mi-ss".
this should get you on the right path:
Dim dt As DateTime
dt = Now
TextBox1.Text = Format(dt, "yyyy-MM-dd HH:mm:ss")
NOTE: this answer was written for a previous revision of the question which had the following code:
Dim Dt As DateTime
If DateTime.TryParseExact("Thu, 09 Dec 2010 16:03:24 EST", "dd.MM.yyyy", Globalization.CultureInfo.InvariantCulture, Globalization.DateTimeStyles.None, Dt) Then
MessageBox.Show(Dt)
End If
The format string that TryParseExact takes as it's second parameter specifies the format of the date in the string passed as the first.
In your case the format string is specifying that the date will be of the format "09.12.2010" for example - just the day, moth and year. However, as the string isn't in that format it won't parse. If you'd just used ParseExact it would have raised an exception.
The MSDN page for the variant of TryParseExact that takes an array of possible format strings has more examples, but non match your format exactly, but working with the format strings used to convert DateTime to string you probably want something like this:
"ddd, dd MMM yyyy HH:mm:ss ???"
but I can't find what you'd need instead of "???" to match the "time zone as string". You might have to do some string manipulation to remove this before calling TryParse or TryParseExact.
You will have to replace the timezone with the timezone offset.
Same question as Parse DateTime with time zone of form PST/CEST/UTC/etc
TextBox1.Text = System.DateTime.Now.AddMinutes(698).ToString("dd/MM/yyyy");
DateTime DOB;
string[] formatsDOB = { "dd/MM/yyyy", "MM/dd/yyyy" };
DateTime.TryParseExact(txtDateofBirth.Text, formatsDOB, CultureInfo.CurrentCulture, DateTimeStyles.None, out DOB);

is there anyway to convert "20180717" in to datetime "MM dd yyyy" format in vb.net
im reading csv file and pick up values related to date all date values are in like "20180717" format need to store thoses in datatable DateTime column in sql
You can also use DateTime.TryParseExact. This method doesn't throw an Exception in case the input isn't valid:
Dim dtValue As DateTime
If DateTime.TryParseExact("20180717", "yyyyMMdd", CultureInfo.InvariantCulture, Globalization.DateTimeStyles.None, dtValue) Then
'The input is a valid date in specified format. The parsed date is now in dtValue
Else
'The input isn't a valid date (in specified format).
End If
DateTime.ParseExact(csvstring,"yyyyMMdd",CultureInfo.InvariantCulture).ToString("MM dd yyyy")
In my SSIS project I have a date variable of type [DT_DATE]
I'm trying to convert rows which contains a string (a date and a time)
The format of the string looks like this: 20151107 19:32:23
I want to convert this into a datetime format before I insert it into my db.
My script looks like this:
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim tempDate As String = Row.calldate
Row.newcalldate = Date.ParseExact(tempDate, "yyyyMMdd hh:mm:ss", System.Globalization.DateTimeFormatInfo.InvariantInfo)
End Sub
I end up with the error: String was not recognized as a valid date
Any help would be much appreciated
In the format string hh stands for the hour using a 12-hour clock from 01 to 12.
So if you want to parse a time expressed in 24-hour clock you need to use HH
Row.newcalldate = Date.ParseExact(tempDate, "yyyyMMdd HH:mm:ss", System.Globalization.DateTimeFormatInfo.InvariantInfo)
I'm taking date from my csv file
Dim odateq As String = sData(0).Trim()
I am getting odateq as 9/15/2015
I want to convert this to 15/9/2015. So I wrote code like this
Dim newdate As DateTime = DateTime.ParseExact(odateq, "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentCulture)
And I'm getting an error like this :
String was not recognized as a valid DateTime.
any help is very appreciable...thanks
the code you wrote is using the wrong format; the date you have is in the format M/d/yyyy (month and day without leading zero are a guess because you did not specify it).
try with this one:
Dim newdate As DateTime = DateTime.ParseExact(odateq, "M/d/yyyy", System.Globalization.CultureInfo.CurrentCulture)
the format you set in the ParseExact was telling the function to expect a date in the format dd/MM/yyyy like 01/05/2015 but what you have is not in that format.
after you parse the input date, to get a string with format dd/MM/yyyy use:
Dim dateAsText As String = newdate.ToString("dd/MM/yyyy")
I have user input that needs to be verified that the string is in the datetime format as follows:
yyyy-MM-dd HH:mm:ss
The user does not have a choice for any other format but for error checking how do I detect whether string in is this format.
sDate = DateTime.ParseExact(startDate, "yyyy-MM-dd HH:mm:ss", CultureInfo.CurrentCulture)
startdate is the string.
This code will help you to convert the date into the format which which you wanted to check
Dim format As String = "yyy-MM-dd HH:mm:ss" 'let input be "02-02-2014 12:12:12"
MsgBox(dt.ToString(format)) ' the output will be 2014-02-02 12:12:12
it works properly in VS 2010(windows 7)
IMHO, you should consider using DateTimePicker control for taking date/time input. Use Custom Format (if needed). It will save you to first take it and validate it.
You should use DateTime.TryParseExact if you want the date/time format to be exactly in a particular format.
Function IsValidDate(ByVal dateValue As String) As Boolean
Return DateTime.TryParseExact(dateValue, "yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture, DateTimeStyles.None, Nothing)
End Function
I'm using vb.net 2005.
How do convert this date / time 21/08/2008 00:21:00 to a DateTime object ?
You can use a custom date time format string in conjuction with DateTime.ParseExact or DateTime.TryParseExact.
Dim dateTime as DateTime = _
DateTime.ParseExact("21/08/2008 00:21:00", "dd/MM/yyyy HH:mm:ss", _
CultureInfo.InvariantCulture)
Dim d as DateTime = DateTime.Parse("21/08/2008 00:21:00")
Console.WriteLine(d)
produces this:
21/08/2008 12:21:00 a.m.
If you want to be sure to parse that format correctly, you should use DateTime.ParseExact with a custom format string matching your pattern (e.g. dd\/MM\/yyyy HH:mm:ss).
I'm using vb.net not c#, my solutions a bit old, but it works
Dim d1 As Date
d1 = CDate("21/08/2008 00:21:00")
Console.WriteLine(d1)
