I need to save datetime value with minutes,seconds and milliseconds in sharepoint 2010 list column.
I tried but my problem is not solved.
SPFieldDateTime doesn't allow to store milliseconds so you will have to create your own SPFieldType (look here for help) or you just have to store your DateTime into a SPFieldText field and process the stored information as needed. You would loose the Datepicker control, but since you require such exact results, that doesn't seem to be a problem.

I have database with a MariaDB backend and a MS-Access frontend. I have a table with a column with the data type set to "time(6)". In my backend, the column only shows time-values between 00:00 and 23:59. There are no dates in that column.
However, when I open the (linked) table in my Access frontend, it shows date AND time in that column. It always shows the current date and the time value from the backend-table. So if the actual value in the field is "16:25", Access will show "07.02.2023 16:25" (current date in German date format).
I have a form in Access where one can edit the data for a specific recordset. In that form there is also a textbox for the time value. When the textbox is not selected, it will show the correct time (e.g. 16:25). However, as soon as I click into the textbox to edit the time, it will suddenly show date and time (e.g. 07.02.2023 16:25). The format of that textbox is set to "Time, 24h" though.
How can I make the textbox show only the time without date, even when the textbox is selected? Why does my Access frontend interpret the time value as a datetime value?
If I set the property "Show Date picker" of that textbox to "For dates", it will show the date picker after selecting the textbox, despite the fact that the format is set to "Time, 24h". This doesn't make sense to me. Any ideas? Thank you!
I updated the ODBC connection to the table several times, but in my frontend there are still datetime values in the column that should only have time values.
Why does my Access frontend interpret the time value as a datetime
value?
That's by design as Access doesn't have discrete data types for date and time.
You can easily read the time only:
=TimeValue([YourTimeField])
An edit can be done in an unbound textbox. Use the AfterUpdate event of this to write the edited time.
Also, see my article:
Entering 24-hour time with input mask and full validation in Microsoft Access.
I wonder if anyone can give me some guidance concerning dates.
I am working on this form that contains a date in a textbox and spinbutton that adds/subtracts a day from this date.
In my system, the current date format is dd/mm/yyyy. But I noticed that if user has another format, the spin button will not work properly.
My questions
Is there any windows api that gets user`s system date format? What about a windows api that changes this format?
What is the best way to work on a solution for dates (I have been having lots of troubles when it comes to dates, not just in this application)
Any advices regarding dates at different systems will be appreciated.
Thank you all
If you are using macro,
Use "Cdate" to convert values to date. it will convert different date formats into similar date format.
It can be used for comparing two different format dates
For Example.
Function MyDate(rng As String)
MyDate = CDate(rng)
End Function
In excel formula, You can use "Datevalue" formula to convert different date formats to similar date format.

I am entering the ate as 31122014 in a text box. on leaving the text box, it should show 31/12/2014 and the same should be store in mdb also. Similarly for date like 01022014 (01-feb-2014) it should show as 01/02/2014 in vb.net.
Date format for display purposes have nothing to do with how they should be stored in a database. If you need to store a date in a database, you use a DateTime column. The only time you need to format a date is to display it to the user. Date formatting should be done in the UI.
It's been a long time since I've used Access, but after you've created the text box on your form, click on it, and check it's properties. You may need to create a custom input mask to do what your asking, but it is possible. Please google search MS Access > Input Mask
For auto date\time we use TIMESTAMP datatype in SQL. What is equivalent to that datatype in MS Access 2007...
There is no exact equivalent in Access.
To clarify, TIMESTAMP in SQL is not always a usable Date/Time, for instance in SQL Server it is deprecated and equivalent to ROWVERSION, which always returns a unique value and it not used to track date and time, even though its value is loosely derived from the current time.
But let's say you want to track changes to records.
In Access, the following ways let you set a field to a DateTime automatically:
First, you can assign =Now as the default value for a DateTime field in a table. This will assign the current time when the record is created (but will not update it automatically when the record is changed).
For recording the current DateTime whenever you make a change, you will have to program that in VBA or through Macros:
When going through a recordset, just update your !ModifiedDateTime or (whatever you called your field) whenever you make a change to a record.
When your table/query is bound to a form, you can let the form update your ModifiedDateTime field by handling the BeforeUpdate event of the form:
Private Sub Form_BeforeUpdate(Cancel As Integer)
ModifiedDateTime = Now
End Sub
If you use a query rather than a table to bind to the form, make sure that the field is present in the query.
In Access 2010 and later, you may also use the new Data Macro, which are the Access equivalent of triggers, to record the current date and time when a record changes.
This is less portable, but would probably be more reliable than using VBA since you don't have to remember to code it whenever you modify a record (Data Macros are handled at the ACE database driver level).
There are tons of articles on how to create audit trails in Access if that is what you are looking for.
DateTime is the only date-based datatype in Access. You would then format the field to either General Date or Long Time to capture down to seconds. I don't think Access gets more accurate than that.
I have a few user controls I made in wpf that are driven by two datepickers. One picker controls the begin of the date range and the other one controls the end of the date range.
I had issues with the datepicker.selecteddate property giving me the time along with the date and then my sql results were not all there because the passed in time value filtered out a lot of my results. I ended up finding that if I formatted that time to midnight then my results were all there, but every time I picked a new selection in the datepicker it would reset the formatted time.
After some testing I found that I can just pass the value of the datepicker text property as the parameter. This property's value is a string type and is set to the date value of the current selected date (ex: 3/14/2012 5:00:32 AM is selected date then '3/14/2012' is the text value).
So far, surprisingly, this seems to return all my results I wanted.
I was wondering about why this actually works (is it b/c the 'mdy' literal format is supported and the default?), and if there is any negative drawbacks to doing what i'm doing? I know a lot of times just because something works doesn't mean you should use it in production. I share the tables with others or I would just convert the datetime fields and parameters to date and be done.
I hope my question makes sense. Sometimes they don't. If there are questions leave comments and i'll chime in.
As far as negative drawbacks, I cannot see any - this is how we handle it throughout many apps/DBs. However, the way I typically handle it is if the record being added doesn't need the time (i.e. BusinessDate, LoadDate) then I add the record with the only the Date and no time - so the value is always in the format 3/14/2012 12:00:00 AM which I think makes querying significantly easier since you don't have to deal with the time
Then in my UI (winforms) when performing a search on the date with a datetimepicker I use the datetimepicker.Value.Date which gives the date in a similar format (3/14/2012 12:00:00 AM).
If you have a field in a table that needs a datetime, then use it and you can search the date by either formatting the date in the table or using date > yourdate AND date <= yourdate which would include the date you are searching.
