.net - .NET DateTime.ToString() - Default Format Setting?
Nov 18, 2011
Is the default format of ToString dependent on anything server related? Here's the issue: I'm testing and have tested an application on my local machine and ToString(), by default, is returning in a format of "MM/dd/yyyy hh:mm:ss tt", however on our server it appears to be returning as "dd/MM/yyyy hh:mm:ss tt" which the consuming application is not expecting and causing errors.
Dim uvExpireDate = DateTime.Now.AddMinutes(1)
Dim token = String.Format(fmtString, uvExpireDate.ToUniversalTime().ToString(), [various other params])
So I made a little program, and when I run it on my computer the Date format displays as DD/MM/YYYY, but when I run it on some other computers it displays as MM/DD/YYYY. Is there anyway to set the default incoming Date format? Or do I just have to be very careful about how I get/set parts of dates?
Why does: DateTime.Now.ToString("M") not return the month number? Instead it returns the full month name with the day on it. Apparently, this is because "M" is also a standard code for the MonthDayPattern. I don't want this...I want to get the month number using "M". Is there a way to turn this off?
I'm just converting a date to a string but I'm getting this error. It's not listed as one of the normal exceptions to the datetime.tostring method. Googling around, it looks like it's an actual bug where it thinks StartDate is an int--but that's no help to me, as I just need to convert the date.
dim StartDate as nullable(of date) dim Date1 as string if not StartDate is nothing then Date1 = StartDate.tostring("yyyy-mm-dd") end if
I have a program that will copy files from 'SWV' to 'SWV20090824' - todays date...It works great, except that todays date is being interpreted as '20093324'.the '3324' portion changes every time, suggesting that it is somehow reading the time or something else instead.[code...]
I want it to look like this: "Done in: 02:02" Can't seem to get the format for the seconds correct for some reason. Is there another method I can use to force the seconds to use two placeholders even for seconds 1 through 9?
I have a situation in which I want to get the hour component of a DateTime, but I want the 12-hour value that would go with an AM/PM. The only way I could find to do this was to use a date format string. Since h is the format character used for this, I figured I would use the method:
.ToString("h")
However, this would give me an error. But when I used it with a space and trimmed it:
.ToString("h ").Trim()
It would work fine. Why am I not allowed to use "h" as a format string?
I want to pick a value from a DateTimePicker in 'MM/dd/yyyy hh:mm tt' format, add 00 as second with it, store it in a DateTime variable and save it to database. Suppose if I pick the value 05/28/2010 9:25 AM or 05/28/2010 9:25:34 AM from the DateTimePicker, it'll be stored in the variable and saved to database as 05/28/2010 9:25:00 AM irrespective of what value is chosen from the DateTimePicker for second. I'm using the following statement but it's getting failed during the format conversion while storing it in the DateTime variable generating an error.[code]

I have two textboxes on the screen. They are used for startdate and enddate. If the user does not enter anything in the textboxes I pass nothing (VB.NET) to the webservice. When the webservice receive it on the other end it shows the value "#12:00:00 AM" which I think is the default for the datetime field. Anyway, now I do not want to pass this value to Stored procedure since it will not work. How can I check before sending values to sproc that the value is not the default datetime.
I currently receive spreadsheets from clients which include several date fields. Since these are coming from many different sources, the date formats can vary widely (although they will all be US format). It could be "April 19, 2010", "4/19/2010", "2010-04-19", etc. I would very much like to use the DateTime.Parse function rather than having to write my own parsing function--I don't want to have to write out every possible combination of date strings.
The problem is, the DateTime.Parse function includes default values if all values are not supplied. So if the field comes in as "03/2009", since no day was specified, the function will return a datetime equivalent to "3/19/2009" (today's day along with the values given). I cannot use this. If a client provides a date that is incomplete, my program must produce an error, not fill in default values for them. Is there a way to tell DateTime.Parse not to use default values? Or perhaps there's another function that can parse multiple string formats into DateTime type without using defaults?
I have this date format yy/MM/dd HH:mm:ss ex: 12/02/21 10:56:09. The problem is, when i try to convert it to different format using this code: CDate("12/02/21 10:56:09").ToString("MMM. dd, yyyy HH:mm:ss") It displays Dec. 12, 2021 10:56:09. How can i correctly format it to: Feb. 21, 2012 10:56:09? This format is returned when i check balance inquiry fro my SMS based application.
I have a data which is 06/03/2010 03:05:22 PM from foxpro database which I need to transfer to mysql database but I think mysql datetime only accept YYYY-MM-DD HH:MM:SS <am I correct?> I am prompted with an error 'Incorrect datetime value: '06/03/2010 03:05:22 PM' for column 'date_update' at row 1'. My question is how can I change the format so I can resolve that error. I'm using vb.net 201...
I'm having a hard time trying to change the format a date time that comes from the atabase.I convert that to a string so i can split date and time into different values.Once i have that, i would like to format the time with the 24 Hour format, instead of the 12 Hour format that i'm getting.
i'm having a problem converting a date to the right format. Below is the code I am using:
Dim getDate As DateTime getDate = DateTime.Now With cmdParent.Parameters .Add("@date_created", OdbcType.DateTime).Value = getDate .Add("@last_updated", OdbcType.DateTime).Value = getDate
[Code]...
This causes the following error: ERROR [HY000] [MySQL][ODBC 3.51 Driver][mysqld-5.5.8-enterprise-commercial-advanced]Incorrect datetime value: '' for column 'date_created' at row 1
This is being inserted in a MySQL db. The date_created column is of type datetime.
I need to have my DateTime format match this type: 2010-04-10T10:00:03. When the user clicks the 'Update Modification Time' button, I need the exact Date and Time, in that format, to be saved in an .INI file.
Need to convert a string to normal datetime format so it can be correctly inserted onto a datetime type field. String Format: 4/21/2010 4:43:03 PM Example: 2010-04-21 16:43:03.000 I have clarified question: The need is to change format and not type.
I am building an appointment booking system web application in asp.net in VB,
Im simply trying to check whether an appointment has been made on a date selected from the calendar control. I am using Linq for the bindings but the format from the calendar is mmddyyyy when i need ddmmyyyy, my appointments entered int sql table as are 20/09/2012 10:00:00
trying to use a linq from p in db.apps where p.date=mycontrol.selecteddate
[Code]......
im not sure if the code DateTime.Parse,,,, is right, there are many appoinments on the selected date which i select from the calendar but i think the DateTime format is not translating into SQL correctly
i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net. I've made many attempts however i'm still getting the error that i have an error in my SQL Syntax. The format that the DateTime in Vb.net is 6/21/2011 12:46:25 PM. I need to convert that to the MySQL DateTime Format which is 2011-06-21 12:46:25 and also is running on a 24 hour clock. I've searched many forums and haven't found a conclusive solution yet. Below is the code i have so far, with attempting any DateTime Conversion.
Imports MySql.Data.MySqlClient Public Class FinalFailedPinNumberAttempt Dim connectionstring As String = "Server=localhost;user id=root;Password=;database=mylaundrycompany" Dim SQLConnection As MySqlConnection = New MySqlConnection

I don't know if my SQL statement is wrong or what but basically I'm trying to select a record where a date column in SQL matches the value selected by the user in a date and time picker control. The format in SQL is IE: '2010-03-23 00:00:00:000'. The date and time picker shows me 'March-23-10'. How can I get it to match up with the way SQL holds it's dates and return a matching record? Is there some intellisense that pops up that
