When I'm generating my database scripts for my project I'd like to manage the date format that is used in the comments in the SQLScript.I have my regional settings set to Australian format, but they seem to be disregarded.

I'm trying to set the format of a column in a datagridview.When I put the format statement in the on load event for the form, it has no effect. When I put it in the cellformatting event I get the "Object reference not set to an instance of an object" error. I checked the column name. What I am doing wrong?
This is the code:Private Sub MeetingTblDataGridView_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles MeetingTblDataGridView.CellFormatting
Me.MeetingTblDataGridView.Columns("Starttime").DefaultCellStyle.Format = "HH:mm:ss"
End Sub What I'm trying to do is get rid of the date part of a Date/Time field (stored in an Access database) in a datagridview column.

example: inside regional date format setting i set "Short date format dd/MMM/yyyy" and inside vb.net program i set "strSQL = strSQL & ",'" & Date(Date.Now.ToString("dd/MM/yyyy")) & "'" ----> working fine. if user changed the regional date format setting to other format like "mm/dd/yy" facing problem during saving record into sql table. error date conversion. It's possible to avoid using computer regional date format from vb.net? or have any other way...

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
I am using ASP.NET with SQL Server 2005.
My date get saved in the database with data type = "smalldatetime".
I am displaying the date value into a text box called txtDate with a Reader......
Dim conn As Data.SqlClient.SqlConnection
Dim Comm As Data.SqlClient.SqlCommand
Dim reader As Data.SqlClient.SqlDataReader
[Code]....
But currently my date get displayed as "2008/06/30 12:00:00 AM" and i want to display it as "30 June 2008".
For example, today is 05/11/2009, I have two text box.
Actually it means that whatever what date i choose within the current month, the two textbox will display the last three months date.
For Example, Current Month is November 2009 , Textbox 1 will show 01/08/2009, Textbox 2 will show 31/10/2009.
Another example is Current Month is January 2009, Textbox 1 will show 01/10/2009, Textbox 2 will show 31/12/2008.
May I know how the vb.net code should look like?
how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.
I have a problem. I'm making a alarm clock and I need a way of converting a "dd/MM/yyyy HH:mm:ss" format into a date time format. This means I'll be able to compare the dates in a listbox using the for each function, to the current date and see whever it has passed and therfore the alarm should be deleted. It is currently in a string form so I can't use < and > to compare it to the current date as that is in a date form. I've tried using CDate but it doesn't work as it only will convert these formats:
"August 12, 2004", "2:07:30 PM" and "August 12, 2004 2:07:30 PM"

View 10 RepliesAll of my regional settings in control panel are set to UK but when I retrieve a date from an SQL database (run from my PC) in my program, it appears in the MM-DD-YYYY format rather than the DD-MM-YYYY format that I expect.
After a bit of troubleshooting I found that this is because of the fact that SQL server always stores its dates in that format - so then when my program reads the data from the database it interprets it as being the US format.How can I convert this to UK format bearing in mind I am working with Date objects not strings?
I am trying to do a custom date format in VB.net using Format. The data coming in is "2009-10-03 00:00:00.000" and I want it to be "OCT 03 2009 12:00AM". I am using Format(object, "MON DD YYYY HH:MIAM") and am getting screwy results ... "2006-09-17 00:00:00.000" becomes "9ON DD YYYY 00:9IA9".

I'm using date in the format dd-mm-yyyy and I need to convert a string inthis format to a date type.My string is "18-01-2010" but when I do the conversion using dim TargetDate as date=CDate(TgDstr).where TgDstr is "18-01-2010", the resutant TargetDate, as note in the debugger window, is #1/18/2010# rather than #18/1/2010# which I expected.What change in code should I made to get the desired result?
