i know that we can do this e.g.
dim str as String = textbox1.text ' when date is in this format dd/MM/yyyy
dim date_time as Datetime = Date.ParseExact( str , "dd/MM/yyyy" , nothing)
it works fine but when the user but the date like this 9/9/2010 it gives error because the format is set "dd/MM/yyyy" and given date format is "d/M/yyyy" or it could be "dd/M/yyyy" what could be the solution of this problem?
I am using Calendar to display Date in Textbox. my Problem is that it works Ok in localhost but when I had uploaded the same, error come "Unable to convert String to datetime".
View 4 RepliesI have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:
DateTime.TryParse(dateTime, out dt);
But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.
EDIT:
I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.

I have an application that uses a time date picker control to display a date from a sql (sql 2000) table. Casting from the table to the control works fine, but writing a selected date from the control back to the database does not, I was under the impression that a datatype 'date' in VB would be compatible with SQL datetime datatime, and obviously it is from sql to vb as the date is correctly displayed in the control reading from the table. How do I need to convert the value from the date time picker control to write into sql ?

I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
I have a string variable like '31/01/2011'.
I need to convert that to datetime variable and store it into oracle. I tried bunch of stuff but it is not working. Can someone post some sample code.

I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:
DateTime.ParseExact(startTime,"MM/dd/yyyy hh:mmtt", null);
Datecol is a datetime in a sql table.
q="select convert(char(8),datecol1,112) from tblone where datecol2 is null"
is what I use for my query string for sqlcommand(). I'm getting the error "a field or property datecol1 could not be found in the datasource". Without the convert, the query is ok.
I have one class for selecting, updating and deleting record in db (sql server 2008) and one class for represent table record, i think it's call 'Activ record' design pattern.
Now, I have GriwView with editing, selecting and deleting items. Data source for this grid is ObjectDataSource:
<asp:ObjectDataSource ID="ObjectDataSource" runat="server"
TypeName="DBOrdinacniDoby.Hours"
DataObjectTypeName="DBOrdinacniDoby.Hour"

Currently I am able to bring the datetime from my SQL table but I also need the milisecods. Here is the line of code:
[Code]....
So latestTimeStamp = {9/22/2010 6:24:09 PM} but I needed it to be latestTimeStamp = {9/22/2010 6:24:09:080 PM}
since the SQL field value is 2010-09-22 18:24:09.080 and I want to do an accurate datetime comparison.
.aspx
[Code]....
And then when I save....cs
[Code]....
And Stored Procedure is like this

the problem is when I use debugging mode, I mean using with visual studio, it's going fine. But when I call from IIS there has a error.. Unterminated string constant. I know where is the problem

I have this example and it gives me exception "Conversion from string x to dateTime is invalid"
here is my method to validate Datetime.
Example Date string : "27/03/1985"
Public Function validateDateColumn(ByRef FieldName As String) As Boolean
Try
If IsDate(FieldName) Then
Dim actualDate As DateTime = CDate(FieldName)
Dim DtLicExp As DateTime = CDate(actualDate.ToString("d", Thread.CurrentThread.CurrentCulture))
FieldName = DtLicExp.ToString("MM/dd/yyyy")
Return True
End If
Catch ex As Exception
'FieldName &= "Format must be MM/dd/yyyy"
Return False
End Try
End Function
validate this date string formate to datetime.
I want to convert this date "27/03/1985" to datetime.
I have a string date like this:
"3/28/2008 12:05:45 pm"
i want to convert it into date and display the out put
I am getting DateString in JavaScript from the TextBox like,
var dateString = document.getElementById('<%= txtEffDate.ClientID %>').value;
dateString value may be in following format.
en-US -> "4/29/2010"
fr-FR -> "29/04/2010"
de-DE -> "29.04.2010"
it-IT -> "29/04/2010"
es-ES -> "29/04/2010"
zh-CN -> "2010/4/29"
ja-JP -> "2010/04/29"
sv-SE -> "2010-04-29"
And converting this to Date Object as follows,
var d1 = new Date(dateString);
though its giving me the wrong result like for fr-FR "29/04/2010" ==> "Fri May 4 00:00:00 UTC+0530 2012"
Which is completely irrelevant, How should I get the correct Date ?
I have also set < globalization culture="auto" /> in web.config & < asp:ScriptManager ID="scr1" runat="server" EnableScriptGlobalization="true"/>

View 2 RepliesI am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.
