String to date

i want ot convert a string to a date
the user enters a date into a text field
i want to convert it to the format dd/mm/yyyy and catch an exception to ensure that its a vaild date

ive been trying that but it does not work
in the following line
myDateFormat.parse(myDateString);
it expects a date between the brackets where the string is
or SimpleDateFormat.parse
e.g.
SimpleDateFormat myDateFormat =new
SimpleDateFormat("yyyy_MM_dd");
String myDateString = "2003_04_24";
Date myDate =
myDateFormat.parse(myDateString);

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Date date=new Date();You don't need this line.
Date dateFormatter = new
er = new
SimpleDateFormat("yyyy'-'MM'-'dd").parse(str1);;As already told, you don't need the single quotes. And you don't need two semi-colons - that's unnecessary.
I just wrote a sample code to test that out. Check it and see for yourself.
import java.text.SimpleDateFormat;
public class Test {
     public static void main(String[] args) throws Exception {
          System.out.println(new SimpleDateFormat("yyyy-MM-dd").parse("2005-04-18"));
          System.out.println(new SimpleDateFormat("'yyyy'-'MM'-'dd'").parse("2005-04-18"));
}Output:

Problem in Converting String to Date

Hi All,
I am having one String
String date = "2006-01-17 15:19:57.0"
I want to parse this String into Date object.
I will really appriciate if somebody helps me out.
Thanks.

You're specifying a 'T' and a timezone in your format, but they're not present in the string you're parsing.
I'm assuming from the way you're printing out the date, that your thinking is along these lines: "sdfInput will parse the input string, no matter what format it's in, and will produce a Date object. That Date object wil have the format specified in sdfInput."
This is wrong on a couple of fronts:
1) DateFormat doesn't magically figure out what format it's supposed to use for the String it's parse()ing. The String has to match the DF's format.
2) Dates don't have formats. Only Strings do. A Date object is just a long. There's no relationship whatsoever between the Date that you get from parse() and the format that was used to produce it. When you print out a Date as you're doing, its toString method is called, which in turn uses a default format for your Locale.
If you want to turn a date string in one format into a date string in another format, use two different DateFormat objects with two different formats. Date date = df1.parse(inputString);
String outputString = df2.format(date);

Conversion of string into date????????????

Can anyone tell how to convert a String into date??
if the string is in the format "Thu Mar 25 17:11:34 GMT+05:30 2004"
i have converted it. code is
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE MMM d yyyy HH:mm:ss");
     dateFormat.setTimeZone(TimeZone.getTimeZone("GMT+00:00"));
Date date = null;
try
          //date = dateFormat.parse(new Date().toString());
          date = dateFormat.parse(dateLine);
     catch(ParseException ex)
but i am not able to specify the year.
so when i getYear on the new Date it return 1970.

@duffymo, I'm pretty sure "d" is good for a two digit date, "dd" gives you zero-padding.
The problem, presumably, is that the format string "EEE MMM d yyyy HH:mm:ss" does not match the actual format "Thu Mar 25 17:11:34 GMT+05:30 2004".
The correct format string would be "EEE MMM d HH:mm:ss z yyyy"

Remove text to the left of a string or data field

Hi there,
i'm pretty new so I am not that clear with the syntax.
I have a field called part id which displays records of the following;
HSV-123456
HSV-1234567
HSV-123456789
I wish to remove the HSV- at the start of the part id. I have used the right function however because some of the parts are longer than others I couldn't do it this way. Is there syntax which removes the first 4 characters of a string or data field?
pls help.

Formatting incoming string with date/time classes?

Hello,
In the software I am writing currently I am @ a certain point talking to an external device. sending requests, receiving responses.
One of the things I find in the response is "20090429094222", as a string.
I cannot change anything to that, thats the way I get it from the device, so thats where I'll have to start with.
As you could probably guess this is a date and a time. Now my question. Is there a good way to format this from 20090429094222
to
2009-04-29 09:42:22
using date and or time classes, not using String operations?
Thanks in advance.

I found a class containing 2 functions who do exactly what I need, for those intrested:
public static Date convertStringToDate(String txtFormat, String txtDate) {
        DateFormat dateFormat = new SimpleDateFormat(txtFormat);
        Date date = dateFormat.parse(txtDate);
        return date;
public static String formatDate(Date date, String txtFormat) {
        DateFormat dateFormat = new SimpleDateFormat(txtFormat);
        String txtDate = dateFormat.format(date);
        return txtDate;
    }Using them this way gives me exactly what I want:
Date dt = DateUtil.convertStringToDate("yyyyMMddHHmmss", incomingDateSTring);
String newDateString = DateUtil.formatDate(dt, "yyyy-MM-dd HH:mm:ss");Problem solved, thanks alot to those who gave me some explanation on the problem.

I'm trying to read the filename, time, constants and comments into four seperate string indicators (the lines for the comments varies for different files). And read the data into a 2-D numeric array. How can I do this? Is there any function that can serch special characters in the spreadsheet file so I can exactly locate where I should start reading the specific data. The following is how the data file appears. Thank you very much.

Hi,
     I'm fairly new to the NI forums too and I think you just have to wait longer. Your post was done right. I do a similiar function as to what you are talking about except I read in numbers from a file. I create an ini file (just a notepad file of type *.ini) that is is set up with sections inside brackets [] and keys with whatever name followed by an = sign. You may be able to use a *.dat file too, I just haven't. Then the vi attached goes to that file and reads the keys from those sections. You just repeat for the different sections and keys you want to read. You can use similar provide VI's to write to that same file or create it. Let me know how that works.

How to convert a string to date and then compare it with todays date???

Hello.
I want to set a format first for my dates
DateFormate df = new SimpleDateFormate("yyyy-mm-dd");
once this is done then I want to convert any string to date object in the above formate
String str="2001-07-19";
Date d = null;
try{
d = df.parse(s);
}catch(ParseException pe) {
pe.printStackTrace();
First of all there is something wrong above,cus what I get for this is
Fri Jan 19 00:07:00 MST 2001
where as it should have been
2001-07-19... to my understanding.
once this part is done I need to get current date in the above set format and compare the
current date and the date I set.
I will appreciate the help.
Thanks

for the output part:
a date is a point in time
the output depends on the format you specify for output
using for example a SimpleDateFormat.
You only specified the format for parsing (which is independent for that of output) so java uses some default format ... see the DateFormat.format() method for details.
for the comparison stuff, I just posted a little code snippet in this forum a few minutes ago.
the hint is: Date.getTime() returns milliseconds after a fixed date

Converting String to Date

Hi All,

Now I want to convert this String to Date with format 'mm/dd/yyyy' , to display as 04/14/2008
Also I want to add 5 days to this date and display the new date 04/19/2008
I don't know How to convert the string which is having date in 'Mon Apr 14 16:07:52 IST 2008' format to format I need.
Please help me.

Hi ,
I wrote a class that tries to parse a String Date and converts it to object. However, I found a very interesting thing while testing this code. I was trying to paarse "2008:03:04 16:21:05" string by using
DateFormat.getDateFromString(null,"2008:03:04 16:21:05" )
It should by pass all try loop accept the one with yyyy:MM:dd HH:mm:ss format. But it went inside the try loop which had MM:dd:yyyy HH:mm:ss format and gave me a wrong date object with year 0171, april 03.
Could any one help me to understand why it is happening? as a work around I put MM:dd:yyyy HH:mm:ss at the end of the program and it is giving me correct object as it did not have to go that far before matching the format.
Thanks,

Validation For Date,String and Date in a reports Region

Apex 4
Good day to all apex users How do I validate a apex_item.text if the value is string the user can only input a string value if it is number then the user can input numbers only and if it is a date the user can only input a date values?

APEX_ITEMS are not part of the default apex gui... In fact they are just functions which returns html.
You can however do some stuff with the attributes parameters. You can find some cool stuff over here: Re: Validation For Date,String and Date in a reports Region
If you want apex validation you need to create a page validation and loop over your apex_items with apex_application.g_f0x

Date has a parse method, and I think DateField has methods
for this.

Date string to Date object

Hi
How would i go about parsing some date strings in DD/MM/YYYY
format into a date objects. I am sure its an easy problem but i
cant find a simple way to do it as most of the API's want it a
differnt format like MM/DD/YYYY
Thanks for any help

Hi,
in the actionscript 3.0 cookbook there is a class DateFormat
described, which allows to parse strings to date objects.
You can download the code of the dateformat.as from here .
