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'm trying to make my string a nice formatted time but the column in the database isn't set up as a date/time field is there anyway I can do this? Here's my query
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"
I have two dates. Date1 and Date2 Date1 contains "10/12/2010 12:00:00AM". Date2 contains "10/10/2010 03:00:00PM" I want to extract only the date from Date1 and extract only the time from Date2 and join them. Example "10/12/2010 03:00:00PM".
I need to convert time to "UTC+03:30 Time Zone" in my web application here is UTC date : DateTime dt = DateTime.UtcNow; Is there any function to convert UTC to my time zone or not ? I don't want to involve myself writing a new function in my application if there is a function in ASP.NET. The application might be hosted in different server in the world and that's exactly why I have used UTC date. I need a function to add 3:30 to the current UTC time.
I have searched a few pages on this (including MSDN) but have not quite reached a solution. I need to convert "16/04/2010 22:39:06" to "2010-04-16 22:39:06.034" (for example).
I have already written an SQL function to do this, but would rather do this in VB.NET if possible. The date value is coming from the Date Created information of a newly uploaded file:
I have an application in asp.net which worked fine untill recently when i changed the datetime format in Regional and Language Settings in Control Panel.The date time format was default when i installed XP. I chose Indian standard time while installing XP.I changed the date time format to dd/MM/yyyy HH:mm:ss. And my application started to throw an exception whenever i tried to insert any datetime in to the table.The exception i get is:System.Data.SqlClient.SqlException: Error converting data type varchar to datetime.
I have an application that I need the user to enter in a date and time: 10/16/2010 1:00:00 PM How can I setup validation to check to make sure the user has entered in the date/time in that manner? I can use the validators in asp.net to check for date and even when I create a custom validator I don't know how to tell if the user has entered the data correctly. I am adding this functionality to an existing system. So I can't change the text box into two fields for validation.
I 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 am getting the "Unable to convert MySQL date/time value to System.DateTime" error because from what I can tell I have a record with 0000-00-00 00:00:00. Now while the data should never be that (it should be null) there are cases when this might happen and I don't want my entire application to crash because of it. I am using NHibernate and I tried adding change my connection string to allow zero datetime so the connection string configuration looks like:
<property name="connection.connection_string"> Server=localhost;Database=user_system;User ID=root;Password=root; Allow Zero Datetime=true; </property>
However I still receive that error. How can I allow NHibernate to allow zero values for timestamp/datetime/data/time?
