How to validate a datetime in a string

Hi Team,
I have a string,How can i validate whethere the string contains a valid datetime or not ?
Thanks in advance.
Regards
Subrat

Hi Subrat,
Look at this excerpt from website:
While there are functions to check if a value is a date (IsDate) or a time (IsTime), PowerBuilder provides no function to check if a value is a valid DateTime. A function to convert to DateTime and check if the value is a valid DateTime is provided in a tip on this site.

Hi,
Create an validation on EMAIL item and select Regular Expression as a validation method.
Write the below coding in the regular expression validation method.

How to validate "string" in multirecord block

Francois,
Thanks for reply,
Acually Kevin used the summary functions in different text items and the 'comparision' function is being called in one of the text item which is having datatype as number, but in case of character we cannot use formula and summary function. May be i am not able to put the things at right place.
Plz explain in detail.
Thanks in advance

Hi superbluesman,
thanks for your quick answer.
I created this expression to validate my specific date format and it works:
^(0[1-9]|1[012]|[1-9])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d

HELP! How to validate DATE?

Hello...
how to validate a DATE variable?
I have used SimpleDateFormat (dd/MM/yyyy).
For some input it worked fine, but for:
12/67/200394 (OK!) <- this is false, right? but not trapped!
1234546 (TRAPPED!)
12/324/1234 (OK!) <- this is false, right? but not trapped!
I need to have a 100% working Date validator.
Plz Help.
Thank you.

Hey -
I used to following code on your dates to get the results you were looking for...
import java.text.SimpleDateFormat;
import java.text.ParsePosition;
import java.util.Date;
public class DateFormatTest {
 public static void main(String[] args) {
 SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy");
 df.setLenient(false);
 ParsePosition pos = new ParsePosition(0);
 String strDate = " 12/67/200394";
 Date date = df.parse(strDate, pos);
 // Check all possible things that signal a parsing error
 if ((date == null) || (pos.getErrorIndex() != -1)) {
 System.out.println("Error: " + pos.getIndex());
 if (date == null) {
 System.out.println("Date is null");
 if (pos.getErrorIndex() != -1) {
 System.out.println("Error index: " + pos.getErrorIndex());
}I hope there's something helpful in there

How to validate XML using java_xml_pack-summer-02?

In jaxp1.1, we validate the xml file in this way:
c:\java -jar Validator.jar myBookStore.xml
However, in java_xml_pack-summer-02, which is latest version of jaxp, the Validator.jar is not available. So, how to validate xml file?
Pls help.

develop your own validator... here is a quick and dirty one, which spits exceptions when error are met:
import java.io.*;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
public class Validator
public static void main(String[] args) throws Exception {
    SAXParserFactory spf = SAXParserFactory.newInstance();
    spf.setValidating(true);
    spf.setNamespaceAware(true);
    SAXParser sp = spf.newSAXParser();
    sp.parse(new File(args[0]), new DefaultHandler());
}

How to validate Email Address in HTML DB Application

Hi,
I have delevoped one Employee Login Details form in HTML DB. But i am unable to validate that email address as i find html db is not supporting String functions like indexOf(char c), substring(int) ect. So please can anybody help me to know how to validate email address that it has @ and . symbol or not.
Thanks in advance.

user529382,
You may be able to use Regular Expressions instead, if you do a search in this forum for 'regex' you should find a few hits.
While I agree that using a regular expression is a great way to verify that the user has entered an email address that conforms to the regular expression rules, it is still nothing more than that....conforming to the regular express rules.
The only way to 100% confirm that an email address is 'valid', is to actually send an email to it, so what I tend to do is to get the user to enter their email twice (in a user registration screen for example), that way you can minimize the chance of 'typos', then send out a 'verification email' that the user has to click a link on to verify they have received it (I'm sure you've seen this type of system before), only when the confirmation is received would I then make the account 'active'.
Hope this helps.

3)Now waht is the problem is , first time page gets render, user will not select any supplier from dropdown and also not clicking go button also , simply user clcik the addsupplier to detail button , i am getting error.
so how to validate addsupplier to detail button, suppose user should not select any row in table region.
i hope requirement is clear you guys.please help me out....
Thanks

Make sure that if no rows are selected either nothing happens or an appropriate message is shown to the user.can you give some example code snippet to add throw appropiate message if user is not selected any row.

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

How to validate numbers in char field.

Hello all,
I have one database column with char data type. This field should allow insert only
numbers [ zero to nine] and plus symbol .. how to validate this?
Pls help me..
I.m using oracle 9i database. So it does not allow REG-EXP and WITH methods.. So give some
sql coding to do this

As this forum is for issues with the SQL Developer tool, you'll probably get more answers in the SQL And PL/SQL forum.
Regards,

How can I get an unsigned char string with nulls from a dll into LabVIEW 6i?

The following ethernet packet data is contained in an unsigned char * string returned from my dll (it's formatted on printing):
Received A 230 Packet On Adapter 0x008F0070
Ethernet Dest: 01.E0.BB.00.00.15 Src: 00.E0.BB.00.DD.CC Type: 0x8868
000000: 01 E0 BB 00 00 15 00 E0 : BB 00 DD CC 88 68 48 41 .............hHA
000010: 00 E0 BB 00 DD CC 80 B3 : 00 00 FF FF 00 02 00 01 ................
000020: 01 00 F0 18 FF 7F 7F FF : FF 7F 7F FF FF 7F 7F FF ................etc., etc.
However, when I read this string into LabVIEW 6i, I only get the following:
01E0 BB
Which is the data before the first NULL or 00 information. I found a "Remove Unprintable Chars.vi" but it
just sees more data before the above string, nothing after, as seen here: 5C30 31E0 BB.
Anybody have any suggestions for how to get the rest of the string? Is there something I can do to further reformat my dll? The dll I'm using is already a wrapper around another dll so I have some flexibility, but the bottom line is, the data I want is in the format of an unsigned char *.

Excellent advice, this mostly works so I have some further questions:
I am just reading network traffic off my ethernet card right now, but here is what I get using my C program to test:
000000: 01 E0 BB 00 00 15 00 E0 : BB 00 DD CC 88 68 48 41 .............hHA

0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 B405 4300 3300 0000 0000 0000 01E0 BB00 0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 F405 1B04 0C04 0000 0000 0000 8000 0000 0000 0000 0800 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
The first thing I notice is that the first 4 bytes are chopped off, and after about 50 bytes, the data is corrupted until the sequence starts to repeat, but this time it starts with the missing 4 bytes and still corrupts after about 55 bytes.
I am expecting the data in LabVIEW to look very similar to the C data because the network packets I am grabbing are pretty consistant, only a couple bytes will vary between them, not the number I am seeing in LabVIEW.
Another side effect I'm seeing is that I can only run my labVIEW code once, if I try running it again it crashes with failures such as:
memory could not be "read"
For reference, I am opening and closing the network adapter inside the read function of my dll, but the pointer seems like it should be intact...
