When retrieving rows from an SQL Server table I use the following code select mydate, Customer, Details from sales where mydatetime >= '" & format (somedate, "MMM d, yyyy h:mm:ss tt") & "'"This works fine unless the clients computers windows Region setting is 'English (New Zealand)'The default time format in windows Region and Language for New Zealand is [code]On computers with this region setting I get an SQL Error 'Conversion failed when converting date and/or time from character string'..If I manually select the other option for AM symbol, PM symbol in Region and Language i.e AM PM the all works fine again..What format string can I use so that above code always works, even if the Region time format is a.m. / p.m.
View 1 RepliesI 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 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"
I have a date entered in from at DateTimePicker (dtDate.Value) and am writing it to an access database. This insert code works without the date, but not with it.

I have a listview that displays date and time from a range that is set from combo boxes: "Start Date" and "End Date".
Then I am printing a block that display Cycle time. This cycle time is coming from "Start Date" and "End Date". I want to change the format of the item displayed in list view after it is printed in the print block in the format as "mm-dd-yyyy".
dtpPurDate.CustomFormat = "dd-MM-yyyy"
dtpPurDate.Text = DT.Rows(i)("PurDate")

If it's d/M/yyyy, it's shown as 01-01-1900.
How should I set the date time picker whatever regional setting is?

The problem is that there is one column in my access database that is formatted as date/time however the only values in the access is time. When I display this table in the DataGridView, it adds this random date from years ago in front of that time. How do I reformat this DataGridView column to only display the time and not the date?

View 8 RepliesI use following code to download a web page source code in my project:
Private Function dlwebFile(ByVal sUrl As String, ByVal sFile As String) As Boolean
Try
Dim wr As HttpWebRequest = WebRequest.Create(sUrl)
wr.Method = "POST"[code].....
The web page I am trying to download is a intranet site. I am periodically downloading the web page for archiving purpose for future reference. The web page will list the current active jobs/projects we work. We process 100's of jobs everyday. The list item will have the Project id, Project name, Project deadline, etc.The download works fine. the web page is downloaded locally. The problem is the date/time format is changed to some other format. If I view the web page in browser, the deadline of one of the project shows as "7/15 03:00".
However, the downloaded webpage shows the deadline of that project as "Wed Jul 14 16:30:00 CDT 2010". I believe it shows in CDT timezone. Also, it shows couple of other timezone too. I think the project might be created from those countries. I am in India timezone.

I am trying to compare the current Date and time with the Date and Time in the database.In the database I have saved the Date and Time as string.
My current program is reading a XML doc and using it then moving it to a different directory to be archived once it is finished using the xml.
I want to be able (upon completion) move and rename the file to a new folder, I want the folder to be the current date/time as well.
So basically have 4/4/2011 9:56AM.xml in the folder 4/4/2011 9:56AM.
getting the function DateTime.Now in a format that can be saved. Folders and files cannot contain the " / " or " : "
A more Sql server type of date would be fine like 24-Jun-89 13:32:22 but I don't know how to get something like that.
I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:
Select
C.Name,
From Clients as C
[code].....
How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).
I am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat

Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
