Is there anything wrong with following snippet of code?
var d:Date = DateField.dateToString(myDateField.text,"DD/MM/YYYY");
testTextArea.text = d.getSeconds().toString();
Error: Implicit coercion of a value of
type String to an unrelated type Date.
Here is your problem: DateField.dateToString's first parameter is supposed to be a date. It then takes that date and returns a string using the second parameter as a format string.
It looks like you're trying to convert the string to a date (the other way around) so you can get the seconds from it and put it in the text area. The DateField control has a selectedDate parameter that will give you the date you need. Then you just run this code to put it in the text area:
testTextArea.text = myDateField.selectedDate.getSeconds().toString();

I'm going loopy....
I want a date, in date format, for example
21/06/2017 17:23:04 GDT
I stamp this on a document, but I then want to display it on my xpage as:
21/06/2017 17:23
But I keep getting different results no matter what I do. I get the date from the onClick of a button using
var dt = new Date();
I then pass this into a function:
function AddObjectivesHistoryItem(doc, dt, action, username){
var ArrDocHistory:array = doc.getItemValueArray("History");
if(ArrDocHistory.length < 1){
// This should always return an object as it is created when an objectives document is first
// created but do this check to be safe and create an array if for some reason it doesnt exist
ArrDocHistory = [dt+"|"+action+"|"+username];
}else{
// append new value to the array
ArrDocHistory.push(dt+"|"+action+"|"+username);
}
doc.replaceItemValue("History",ArrDocHistory);
doc.replaceItemValue("LastUpdatedByName",username);
doc.replaceItemValue("LastUpdatedDate",dt);
}
I've tried using toLocaleString() and all others it seems but it wont work.
For example, toLocaleString() displays as 13-Mar-2018 15:02:15 on my xpage. It's close to what I want except it uses hyphens instead of slashes, and also displays the seconds.
I've tried using custom date pattern on my date field properties with no luck and I'm certain I'm missing something super obvious!?
Any pointers on how to firstly get the date like 21/06/2017 17:23:04 GDT and store as a date and secondly to then display it as 21/06/2017 17:23, this can be a string if it needs to be.
Thanks
You can get your date value as String in SSJS with:
var dateTimeFormat = new java.text.SimpleDateFormat("dd/MM/yyyy kk:mm");
var dateTimeString = dateTimeFormat.format(dt)));
If you want to store as text, java.text.SimpleDateFormat is best for converting a date server-side to a specific text format. It can also be used in a converter to manipulate to/from as well.
I want to add one second to random time in ISO format, e.g.
var t = "2015-01-13T00:00:00+11:00";
moment(t).add(1, "second").format(); // expected "2015-01-13T00:00:01+11:00", but get "2015-01-12T18:00:01+05:00"
So it converts t to current browser timezone (+05:00 in my case) and only then adds a second.
How can I drop timezone before adding and return it after?
I found:
moment.parseZone(t).add("1", "second").format(); // "2015-01-13T00:00:01+11:00"
I am trying to format a zero currency value as an empty string, so that when the currency value is 0.00 then an empty string gets displayed rather than $0.00.
This code is part of an ASP.Net app that will display currency value to end user.
I have used following code to achieve this goal.
Question : Is it possible to achieve this by just using {0:C} format string or another version of this format string instead of using if then else coding for this? If I use ###,###,###.## as the data format string then an empty string shows for zero currency value and also I get rid of the if then else coding but for non-zero values no currency symbol shows.
If Double.Parse(Decimal.Parse(CDec(currencyValue))) = 0 Then
charValue = Nothing
Else
charValue = String.Format("{0:C}", CDec(currencyValue))
End If
UPDATE
I ended up using the following code, which is working fine. If is better than IIf because it does short-circuiting, which means that IIf will evaluate all expressions whether the condition is true or false but If will evaluate the first expression only if condition is true and evaluate the second expression only if condition is false.
Dim d As Decimal
Decimal.TryParse(currencyValue, d)
charValue = If(d = 0D, Nothing, String.Format("{0:C}", d))
I don't think there is a way using formatting to display an empty string.
But you can write it like:
charValue = If( currencyValue = 0D, "", currencyValue.ToString("C") )
using the If Operator (Visual Basic).
Also this is something I would not do:
If Double.Parse(Decimal.Parse(CDec(currencyValue))) = 0 Then
If currencyValue is Decimal:
If (currencyValue = 0D) Then
If currencyValue is Double:
If (currencyValue = 0R) Then
Also, if you are using a database and this is a Sql Server mind SQL Server Data Type Mappings
I don't think you can when using C or the other similar standard formats, since they are already defining a culture-specific format that will include a format for zero.
But if you specify your own custom format, you can specify three different formats separated by ;s, one each for positive numbers, negative numbers, and zero, respectively.
For example (giving an empty string for the zero format, resulting in blank zeroes):
charValue = String.Format("{0:#,##0.00;-#,##0.00;""""}", CDec(currencyValue))
And from what I can see, omitting the format for negative gives a default that matches the positive, whereas omitting the format for zero gives blank, which is what you're looking for, so this should be sufficient as well:
charValue = String.Format("{0:#,##0.00;;}", CDec(currencyValue))
(Using whichever custom format you wish.)
UPDATE: You can get the current currency symbol and manually put it into your custom format. IE:
Dim symbol = CultureInfo.CurrentCulture.NumberFormat.CurrencySymbol
charValue = String.Format("{0}{1:#,##0.00;;}", symbol, CDec(currencyValue))
From the sound of it, though, I think I would actually recommend doing basically what you started with, maybe with an extension method.
<Extension>
Public Function ToCurrencyString(pValue As Decimal) As String
Return IIf(pValue = 0, "", pValue.ToString("C"))
End Function
Dim someValue As Decimal = 1.23
Console.WriteLine(someValue.ToCurrencyString())
This gives you exactly what you're looking for. The exact same format as C gives, but with blank zeroes.

foreach (var item in elements)//send this error

System.FormatException: The string was not recognized as a valid DateTime. There is a
unknown word starting at index 0.
why error?
Try to change it as follows:
var elements = from element in doc.Descendants("CalendarFair")
let start = element.Element("DateStart").Value
where DateTime.Parse (start)==DateTime.Now.Date
select new
{
dateStart = start,
dateEnd=element.Element("DateEnd").Value,
title=element.Element("Title").Value,
idExcutive = element.Element("IdExecutive").Value ,
};
EDIT: based on the XML you have posted the query above works pretty well. Try to test it with this input:
<CalendarFairs>
<CalendarFair>
<DateStart>2011-04-05T00:00:00</DateStart>
<DateEnd>2011-04-09T00:00:00</DateEnd>

<IdExecutive>2</IdExecutive>
</CalendarFair>

Note that I have inserted today's start date. Actually I think the result was empty just because there weren't entries with actual date.
It sounds like one or more of your input <DateStart> strings is not in a valid DateTime format.
Can you post some sample input XML?
It may be that you need to provide the date format using ParseExact - http://msdn.microsoft.com/en-us/library/w2sa9yss.aspx
Afternoon all.
A very simple one for you today from thicky Rich.
I have a label I want to display as a lovely number format i.e. {0:N0}
Now, this label text equates to a query string value.
How do I go about formatting a label's text from a query string value in one fell swoop?
I have tried this
lblTotalPurchQS.Text = String.Format("{0:N0}",Request.QueryString["totalpurchasequantity"].ToString());
but with little success.
Any ideas or pointers?
Don't use ToString on the incoming query string parameter, but convert it to an int first:
lblTotalPurchQS.Text = String.Format("{0:N0}", int.Parse(Request.QueryString["totalpurchasequantity"]));
Note:
The above is not safe code. First, the conversion may fail with a conversion exception. You should also be HTML escaping the output, in case of XSS.
This is better:
int totalPurchaseQuantity;
if(int.TryParse(Request.QueryString["totalpurchasequantity"], out totalPurchaseQuantity))
{
lblTotalPurchQS.Text = Server.HtmlEncode(String.Format("{0:N0}", totalPurchaseQuantity);
}
