I'm calling a webservice through Ajax that only accepts datetime parameters as a 'long' type (representing the ticks).
Is there anyway to have a datetime input field on a form that represents this?
I would like to have a Date and Time selector (with a calendar and those kind of eye candy) that internally send the field value (or at least exposes the value) as Ticks.
I'm going to assume by "ticks" you mean milliseconds since epoch. You could use an existing plugin like http://eonasdan.github.io/bootstrap-datetimepicker/. It supports both date and time pickers. From there, simply grab the value and run it through new Date('supported format here').getTime() to get the milliseconds value. If you're looking for a pure HTML5 way, unfortunately that isn't possible.

Is is possible in a Table to Calculate differences between Dates if the Value in the field is considered "short text"?
I am working to convert an Excel macro database into Access one and I have imported the data from the Excel file into an Access Table.
however i realized 2 feilds that count up until closure are now just fixed numbers but need to add up as each day passes until closure
when i imported the Dates became Short Text.
is there an expression that would handle this situation?
Each record has a serialized non repeating ID number seperate from access as well.
Dates I have are
OfficialissuanceDate,
DatePlanSubmitted,
DatePlanCompletedSubmitted,
DateClosed,
I need 2 calculations that increments daily when DateplanSubmitted and DatePlanCompletedSubmitted are null
Both comparing to OfficialIssuanceDate. then stop counting when they are no longer null. (have a date in updated to the record) and retain the value.
I have tried to Google calculating Dates but i get DateDiff function which doesnt appear to work. I've used Access and taken a class on it but never really made a new DB from scratch
Dates in a text field are not actual dates, just strings of characters. A Date/Time field stores value as a double number then displays in a date structure - "dd/mm/yyyy" is Access default structure.
Sometimes Access will do implicit conversion of data but not in this case. Either change field type to Date/Time or do conversion with CDate() function. However, you will find that conversion functions error with Null input.
Arithmetic operation with Date/Time field type is possible. However, arithmetic when any term is null returns Null so have to deal with that. One way uses Nz() function: Nz([DateClosed], Date()) - [DateOpened]. Unfortunately, Nz() is not available in table Calculated field type, so do that calc in query or textbox. Most developers avoid table Calculated field type. If you really want to use, expression would have to be: IIf(IsNull([DateClosed), Date(), [DateClosed]) - [DateOpened].
I have a report which requires user to type the start date and also allow them to choose from calendar. I was wondering if its possible to enter the date as a string. Right now, I have a text field with calendar and I would like the user to enter date[06302015] instead of [06/30/2015]
can we omit the dashes and still have the report format it to date?
The type of a parameter can be changed from Parameter Properties like below.
This will remove the Calendar and it will be only a Text box.
Change your parameter type to "Text".
Add a second "Hidden" parameter (as Date/Time data Type) that takes the LAST_DATE_EDITED as an input into the 2nd parameter's default value using the expression: =DateValue(Mid(Parameters!LAST_DATE_EDITED.Value,1,2) & "/" & Mid(Parameters!LAST_DATE_EDITED.Value,3,2) & "/" & Mid(Parameters!LAST_DATE_EDITED.Value,5,4))
(Not tested, but it should be close)
Then use the 2nd parameter in your report instead of LAST_DATE_EDITED.
If the user inputs an incorrectly formatted string of numbers, uses text, etc., SSRS will throw an exception.
IMO, this isn't the most elegant solution and it demands user input that is prone to errors. Not what I would implement (I would have the users use the built in DateTime picker and train them to use valid separators such as periods, slashes or dashes or just use the calendar control).
The default value of the form input should be the current time. The user should can select to provide a time in the future and than a normal datetime field should be shown. Can this be realized without javascript and how?
You can leave the input empty and change it to the current time on the backend (or maybe set it to the current time at the moment of rendering template and interpret past times as "now"). But the most you can do without JavaScript is adding a comment that empty input means current time. If you want to make some kind of fancy checkbox for current time and maybe hide the datetime input, you should do it with JavaScript
You can try to use <input name="date_input" type="date" id="date_input"> in your template.
And do views do :
from datetime import datetime
# get a string from a POST like "10/2/2018"
date_get = request.POST.get("date_input")
# format of date/time strings; assuming dd/mm/yyyy
date_format = "%d/%m/%Y"
# create datetime objects from the strings
date = datetime.strptime(date_get, date_format)
# Check if we have a datetime
print(date)
datetime.datetime(2018, 2, 10, 0, 0)
In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them.
What event can I use?
I've tried:
LostFocus & BeforeUpdate: too late (validation fires before event)
Dirty & OnChange: too early (they haven't left the cell yet)
Or is there a way to turn off the native validation rule that is checking for date formats?
You could use an additional text field without formatting (or with your very own format). Then show this instead of the datetime-field and update the date-time field with your code.
Not very pretty, but if you always format the input to a proper time string on before-update and never access this field (but rather the real date-time field) you should be ok. You could even name the field Helper_DateTime or somesuch, so you are never tempted to access the field from anywhere else ;)
i have a date/time field called MyDate. Originally, its format is mm/dd/yyyy and there is no input mask. The Date Picker is also set. I then added input mask using Short date , changed the default input maks to (99-99-0000;;_) and change the format to mm-dd-yyyy. However, when i switch to DataSheet view , all my dates are changed from mm/dd/yyyy to mm-dd-yyyy (which is the correct behaviour right? ) and when I tried to enter a new date or modify existing date, it says "The value you entered does not match Date/Time data type in this column". Plus, the DatePicker is missing. How can I resolve this. thank you
The date time picker is not available if an input mask is applied to a field: http://office.microsoft.com/en-us/access-help/add-and-customize-date-and-time-formats-HA010078108.aspx#_Toc272229486
Regarding the error, have you considered using your regional settings in the control panel, which sets the defaukt date display for all (most?) applications?
Dates in Access are stored as numbers, so you can format them however you like, but I suspect the input mask may need to match the regional settings, although I am not certain.
