I need to be able to do enter a workshift in a program. In access it made no issue of the fact that date/time was the format. Now in my program when I enter a shift for example
begin: 08:00:00 end: 16:00:00
t converts it to this in MySQL
2008/00/00 00:00:00 and 2016/00/00 00:00:00.

I have two datetimepickers on my form to set a start date and end date for a SQL server database query. I am passing these dates with parameters to my query from the .Value of the datetimepickers. When I run the program, the code returns an error of "Conversion failed when converting datetime from character string" I am not converting anything in my code. It is my understanding that the StartDatePicker.Value is already a datetime and does not require conversion.
Here is some code:
'Define Wages_Query
Dim Wages_Query As String = _
"SELECT [Department], [Operation_NUM], sum(STWag) as [STwag], SUM(OTWag) as [OTWag]," & _
" SUM(Shift_Diff) as [Shift_Diff]," & _
" SUM(COALESCE(STWag,0) + COALESCE(OTWag,0) + COALESCE(Shift_Diff,0)) as [TotalWages]" & _
" FROM dbo.Financial" & _
[Code] .....

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'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 am getting this datetime format in an xml file:
2012-06-14T11:15:41.587-07:00
2012-06-14T10:49:32.397-07:00
2012-06-11T11:10:49.2-07:00
I believe I understand some of it, please correct me if I am wrong:
2012-06-14 = date
T = time identifier
10:49:32.397 = hour min second milliseconds
-07:00 = I have no idea
I need to convert this to something I can sort on for my datagrid view.
When I try something like this:
Console.WriteLine(String.Format("{0:d/M/yyyy HH:mm:ss}", "2012-06-14T10:49:32.397-07:00"))
I'm getting the original string back out with no conversion.

I have the following string:
20111209
How do I turn this into a DateTime Value? I've tried Convert.ToDateTime(s) normally but it keeps yelling that I'm doing things wrong because the string doesn't look like a datetime value.

I am creating a asp.net web page. i have 2 textbox's that I am adding together to give me 1 value. the 1st textbox is using an ajax calendar extendar for the calendar date in MMDDYYYY format and the second textbox is using a HHmmsss format. So if I'm correct both should be in datetime format. Perhaps I'm wrong on the second textbox. I am still realatively new to vb.net so bare with me. How do I correct or make sure that my formats are correct. Or what code do I need to change to make sure that it is in the correct format. The SQL table field is in DateTime format.

In my VB project I am returning an SQL datetime field to a date variable mdtCreated = CType(oReader("dtCreated"), Date) In an example it returns mdtCreated as #5/13/2011 2:59:43 PM# which is correct. Later on I want to show this as a string to dd/mm/yyyy format. I have tried mdtCreated.ToString("dd/mm/yyyy hh:mm:ss") But that returns "13/59/2011 02:59:43". I want it to return "13/05/2011 14:59:43" How can I achieve this?

I wish to convert my string in format dd/mm/yyyy hh:mm:ss to a DateTime of the same format.
Dim ukCulture As System.Globalization.CultureInfo = New System.Globalization.CultureInfo("en-GB")
Dim myDateTime As DateTime
myDateTime = DateTime.ParseExact("18/05/2010 23:42:10, "dd/MM/yyyy HH:mm:ss", ukCulture)
When I step through this code the variable myDateTime is 05/18/2010 23:42:10 it appears that the dd/mm is the wrong way around and I cant work out how to correct this.

I can't seem to be able to convert a string that contains date value of "100714 0700" (2010-07-14 7am) to a date format in vb.net 2005.
When I attempt to do:
Dim provider As Globalization.CultureInfo = Globalization.CultureInfo.InvariantCulture
strPickupDateTime = DateTime.ParseExact(txtPickupDate.Text, "yymmdd", provider)
I get back "1/14/2010 12:07:00 AM". How can I get a value of "2010-07-14 7:00"?
