i have implemented validation for YYYY-MM-DD 
but how to validate for time 
here is the code for date validation
could you please anyone help me on this issue
 public static boolean validateDateFormate(String date) 
{ 
 try { 
 String dateFormat="yyyy-MM-ddYYYY-MM-DDThh:mm:ss";
 String temp = date.substring(0,date.indexOf("-"));
 if(temp.length()!= 4)
 return false;
 SimpleDateFormat df=new SimpleDateFormat(dateFormat);
 Date date1=df.parse(date);
 String resultDateString=df.format(date1);
 System.out.println("date1"+resultDateString);
 if ( !date.equals(resultDateString)) { return false; }
 } catch (Exception de) {
 System.out.println(de);

Validate date ?

Dear All,
May I enquire how to validate date for:
textDateofLoss.getText()
Is it:
if isDate(textDateofLoss.getText()){
//True date
else{
//False date}
Please advise.

Sorry, have to use the following:
import java.util.*;
import java.text.*;
public class validateDate {
public static void main(String args[]) {
String dt = "10-10-1990";
String format = "dd-mm-yyyy";
// String dt = "1990-10/10" throws a ParseException
// String dt = "1990-10-35" throws a IllegalArgumentException
try {
//DateFormat df =
//DateFormat.getDateInstance(DateFormat.SHORT);
SimpleDateFormat df = new SimpleDateFormat(format);
df.setLenient(false); // this is important!
Date dt2 = df.parse(dt);
System.out.println("Date is ok = " + dt2);
catch (ParseException e) {
System.out.println(e.getMessage());
catch (IllegalArgumentException e) {
System.out.println("Invalid date");
}

Validate date using RE

Hey guys,
Need to validate date using RE in format MM/DD/YYYY and optional HH:MM:SS
I already have simple solution, but would like to add checks for leap year and dates like 02/30/2006 or 04/31/2006
So far I have this:
private static final String datePattern =
"^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\\d\\d" +
"(\\s(([0-1]?[0-9]|2[0-3]):([0-5]?[0-9]):([0-5]?[0-9]))){0,1}$";

A much better way is to specify the format of the data and parse it using the SimpleDateFormat class method parse.

Validate Date and block JavaScript page change

how I can validate date acrobat, can block JavaScript page change, only change with a button?

If you use the "util.scand" method date validation is part of the process. It either returns the number of milliseconds from the Epoch date used by JavaScript for the date time object the null value.
Date Arithmetic has some sample scripts, but you need to keep in mind that Date and Time are not independent and using "new Date()" returns the date and time at the time that line of code is executed and that can cause issues for the computing of dates only.
Are you sure of day count, most differences include the start and end dates in the number of days for the calculation.
Custom calculation for today's date field (format is None):
// get today's date an time
var oToday = new Date();
// set to start of day
oToday.setFullYear(oToday.getFullYear(), oToday.getMonth(), oToday.getDate(), 0, 0, 0, 0)
// set field value
event.value = util.printd("d/mm/yyyy", oToday);
Custom calculation for the difference in days field (format None):
var cEnteredDate = this.getField("EnteredDate").value;
var cToday = this.getField("Today").value;
event.value = "";
if(cEnteredDate != "" && cToday != "") {
// process only if date values not empty
// convert date strings to date time objectat midnight
var oEnteredDate = util.scand("d/mm/yyyy", cEnteredDate );
if (oEnteredDate == null) {
app.alert("Error in processing entered date", 2, 0);
oEnteredDate.setFullYear(oEnteredDate.getFullYear(), oEnteredDate.getMonth(),oEnteredDate.getDate(), 0, 0, 0, 0)
var oToday = util.scand("d/mm/yyyy", cToday);
if(oToday == null) {
app.alert("Error converting today", 2,0);
oToday.setFullYear(oToday.getFullYear(), oToday.getMonth(),oToday.getDate(), 0, 0, 0, 0)
// convert date objects to days
var nEnteredDate = Math.floor(oEnteredDate.getTime() / (1000 * 60 * 60 * 24));
var nToday = Math.floor(oToday.getTime() / (1000 * 60 * 60 * 24));
// compute & format the difference
event.value = util.printf("%,0 1.0f", (nToday - nEnteredDate));

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

ERROR [HY000] [DataDirect][ODBC Progress OpenEdge Wire Protocol driver][OPENEDGE]Invalid date string (7497) (pgoe1022.dll)

I am selecting data from a Progress database using the Data Direct Open Edge 10.1.B driver. The target table stores the date values as varchar in this format "22-OCT-14" In the select statement I can use Progress statements or T-SQL to transform
the varchar to a date - but cannot do the same in the WHERE clause
Select po_number, cast(po_date as date) as [po_date] from [po_table]
(no problem - the [po_date] field stored as "22-OCT-14" is returned as "2014-10-22 00:00:00"
but when I include the cast in the where clause I get the error described in the title
Select [po_number], [po_date] from [po_table WHERE cast([po_date] as date)<= '10/22/2014' - NO GOOD
I have tried very many combinations of the date string format , different functions and sub-queries but cannot find an answer

The sql strings I posted are working examples - I've tried the ISO format you included - any number of date formats will work when the target field is a "Date" field - but trying any kind of transform statment to processa date stored
as a varchar in the WHERE CLAUSE throws the erro
Storing dates in a varchar column is a bad idea on any platform. Apparently there are strings in that column which cannot be converted to dates.
On SQL Server you could have found this with
SELECT po_date FROM po_table WHERE isdate(po_date) = 1
What you should use on Progress, I have no idea.

Converting to a date string

I am running the following select statement into Oracle SQL Developer.
Select I_NOTE_DESIGS.END_DATE AS ENDDATE
However in my results the date hows as 01-APR-29.
I was wondering if there is a way to convert this over to another date string ie: I would like the date in this column to show 2029-04-01. I am not bothered if the time comes out at the end, as I have a program which can delete that.

Hi Jon, and welcome to the forums.
I was wondering if there is a way to convert this over to another date
string ie: I would like the date in this column to show 2029-04-01.
I am not bothered if the time comes out at the end, as I have a program which can delete that.select to_char(to_date('01-APR-29', 'dd-MON-YY'), 'yyyy-mm-dd') from dual;
select to_char(to_date('01-APR-29', 'dd-MON-YY'), 'yyyy-mm-dd hh:mm:ss') from dual;
Please be sure to read the forum FAQ. Also, read the "sticky" thread by BluShadow at the
top of the list of posts on the forum home page.
Always give your version of Oracle - the answer can vary greatly with version - although
not in this case.
These forums are a great resource - you will get the maximum benefit from them

How do I find the frequency of numbers in a group of data strings?

I have a set of data strings and I want to find the frequency of each number occuring in a data string. How do I do this?
Here are the strings.
28-29-43-51-53 7
02-08-30-36-48 31
09-10-27-36-42 11
20-24-31-33-36 44
16-29-48-52-54 5
06-15-29-39-51 36
01-16-18-25-27 3
09-30-39-42-47 37

The first part is to "break out" the values from your strings. Columns B thru G take care of this:
I assumed allvalues as 2 digits...
B2=VALUE(MID($A2, 3*(COLUMN()-2)+1, 2))
select B2 and fill to the right until column G
then select B2 thru G2 and fill down as needed.
For compactness of THIS presentation I added two additional columns for getting the Frequency... columns I and J.
Column I contains an counting value and J contains the frquency of the corresponding value in I (of the same row).
put a "1" in I2, a "2" in I3, then select both I1and I2, then grab (click and hold the little circle at the bottom right of the selection), and drag down until the value is the max number you expect (I assumed it was 99).
J2=COUNTIF(B:G, "="&I2)
select J2 and fill down

Reading a flattened LabVIEW data string from a CSV file in C#?

We're recording a large amount of data into a CSV file to make it easily accessible from the C# end. I've a header with all the variable names then I write all the data (doubles) as flattened LabVIEW binary strings using flatten to string (little endian) to keep the size down. We are having issues converting these strings back to doubles on the C# end.
At the C# end we can read the LabVIEW repesentation of the DBL but have tried the BitConverter.ToDouble library function to convert it without luck. We use this method to convert the same flattened data coming over a TCP connection without any problems. I'm not writing the C# part of the program and have little experience with it, but if anyone could shed some light, it would be greatly appreciated.
Regards,
Andrew

It is all written as single values. It looks like we have found a method if we remove the header which contains the variable name as a string so the data is in a csv containing just the binary data strings. It looks like we'll go with this as the data will always be written in the same order so can be indexed by the C# program without the need for headers.
Thanks.

How to validate Date

Hi,
We have a date field in the form. I am validating date format as YYYY-MM-DD, validation works fine. But If user enters invalid date, how to validate date? For examples:
2006-02-31 It is an invalid date. How can i validate it.
If anybody have sample code, it will help me a lot.
thanks
Neopal.

Hi Neopal,
You can use something like the following to test the date is valid, use the validation event on the <Field> which you want to validate to call a Rule something like this (not complete)..
<Rule name='isDateValid'>
 <RuleArgument name='date'/>
 <block>
 <script>
 var dateToTest = env.get('date');
 var formatter = new java.text.SimpleDateFormat('YYYY-MM-DD');
 Date validDate = formatter.parse(dateToTest);

Function Module to validate date

Hi,
Is there a Function module to validate date in transfer rules or update rules. I checked the forum, couldn't find an answer. Any help is appreciated
Thanks

You should be able to use this FM:
CALL FUNCTION 'RSAR_DATE_CHECK_PLAUSIBILITY'
EXPORTING
i_date = yourdate
EXCEPTIONS
PLAUSIBILITY_CHECK_FAILED = 1

Validate Date Range in inputDate component

Hi
I am using JDev 11.1.1.2.0
I have an inputDate component which on click i need to give dates from today to future dates not passed dates.
So i have included 'validate date time range' component in the inputDate component and in the minimum property i have declared 'adf.currentDate' using expression builder and set the maximum as Jan 31,2099.
But when i execute my application i am able to select passed dates using the inputDate component, please help how can i check the date using a validator in inputDate component.
Thanks
Sudeep

ya i had tried with that property too....
i have declared minValue as adf.currentDate and on that it changes the value of maxValue to current date in Jan 3,2012
i have convertDatetime component in my inputDate to display the selected date in certain format.
It gives error as the format doesnot matches with the convertDatetime and inputDate component.
How can i use the minValue and maxValue of inputDate component?
the component:-
<af:inputDate
label="Planned Termination Date"
id="id2"
value="#{modifyuser.pterminationdate}"
valueChangeListener="#{modifyuserfields.plannedTermDate}"
minValue="adf.currentDate" maxValue="2099-12-31">
<af:convertDateTime pattern="dd-MMM-yyyy"/>
</af:inputDate>

Validate date of Birth

How I can validate date of birth?
Month-Date-Year
Example: 11-21-1960
Thanks

You could use a regular expression:
E.g.
var dateRegExp = "^(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])-(19|20)\d\d$"; // mm-dd-yyyy
if (oField.rawValue.search(dateRegExp) === -1) {
// error!
Or you could use a date object as suggested in the previous post, but also stop the user from typing in a date so they will be forced to use the date selection box. This would ensure that the date is always in the correct format. To stop the user from typing in data, put the following code in the change event for the field:
if (xfa.event.change.length == 1) {
xfa.event.change = "";
