Validation on integers

Hi,
Can any one help me with a validation on an item that only accept integers. The Item is not a column in de table.
ekas

couldn't this be better achieved on a client side validation?
anyway
WITH t AS (SELECT '123E' txt FROM DUAL
           UNION ALL
           SELECT '123' FROM DUAL
           UNION ALL
           SELECT 'E123' FROM DUAL
           UNION ALL
           SELECT 'E' FROM DUAL
           UNION ALL
           SELECT '1.23' FROM DUAL)
SELECT txt,
       CASE REGEXP_REPLACE (txt, '[^[:digit:]]')
          WHEN txt THEN 'Integer'
          ELSE 'not Integer'
       END
          int_indicator
FROM t
TXT,INT_INDICATOR
123E,not Integer
123,Integer
E123,not Integer
E,not Integer
1.23,not Integer

How to add a "global" counter in uccx?

Hi
my customer has UCCX 8.5 Enhanced and he cannot afford an upgrade to Premium.
They need to know how many times an option has been pressed by the users along the time. That option has only a "play prompt" step.
I thought about using an XML file and, every time that option was pressed, I would increment the variable inside it.
The problem is that, inside the script, I cannot increment the string extracted from the xml file. That is only valid for integers.
Does anyone have an idea about how to get it?
Thank you
Marcos

You would run into issues using an xml document within uccx is having multiple updates as you have overlapping contacts.
From what I have seen while testing at run time the xml document is loaded into memory for that script. Let's say the value is 1. If the script is executed again before the other one has completed it will also read the value as 1. The first script has completed and updates the document to a value of 3. The second script is not aware that the value was updated to 3 and will rewrite the value based on the starting point of 1 which will result in the data being lost.
What you might be able to do is use the Create URL Document step to Post data to another server and have it do all of the calculations on the back end.

REST API: Create Deployment throwing error BadRequest (The specified configuration settings for Settings are invalid. Verify that the service configuration file is a valid XML file, and that role instance counts are specified as positive integers.)

Hi All,
We are trying to access the Create Deployment method stated below

We have uploaded the Package in the blob and browsing the configuration file. We have checked trying to upload manually the package and config file in Azure portal and its working

INFOPATH: Only Integers allowed validation tooltip

I have a few lookup columns in an InfoPath library form template. The underlying fields are integer numbers, and the control is a dropdown which is populated from a secondary data connection. If the field is mandatory, a little validation tooltip reminds
you "Only integers allowed". My users will be confused by such information. Is there a way to overwrite this message or at least switch it off? Thanks. Iko

Any luck in solving this issue?
Ok, this workaround helped me forward. Uncheck the option "Cannot be blank" on the drop down list. Instead, if you need validation and the field is mandatory, create a validation rule on the InfoPath control. its the same function, with a more meaningful message
that you can customize.
Hope it helps..

Reading strings and integers from a text file

I want to read the contents of a text file and print them to screen, but am having problems reading integers. The file contains employee's personal info and basically looks like this:
Warren Laing
32 //age, data type is int
M //gender, data type is String
Sharon Smith
44
F
Here's what I've done so far. The method should continue reading the file until there's no lines left. When I call it from main, I get a numberFormatException error. I'm not sure why because the data types of the set and get methods are correct, the right packages have been imported, and I'm sure I've used Integer.parseInt() correctly (if not, pls let me know). Can anyone suggest why I'm getting errors, or where my code is going wrong?
many thanks
Chris
public void readFile() throws IOException{
BufferedReader read = new BufferedReader(new FileReader("personal.txt"));
int age = 0;
String input = "";
input = read.readLine();
while (input != null){
setName(input);
age = Integer.parseInt(input);
setAge(age);
input = read.readLine();
setGender(input);
System.out.println("Name: " + getName() + " Age: " + getAge() + " Gender: " + getGender());
read.close();

To answer your question - I'm teaching myself java and I haven't covered enumeration classes yet.
With the setGender("Q") scenario, the data in the text file has already been validated by other methods before being written to the file. Anyway I worked out my problems were caused by "input = read.readLine()" being in the wrong places. The code below works fine though I've left out the set and get methods for the time being.
Chris
public static void readFile()throws IOException{
String name = "";
String gender = "";
int age = 0;
BufferedReader read = new BufferedReader(new FileReader("myfile.txt"));
String input = read.readLine();
while(input != null){
name = input;
input = read.readLine();
gender = input;
input = read.readLine();
age = Integer.parseInt(input);
input = read.readLine();
System.out.println("Name: " + name + " Gender: " + gender + " Age: " + age);
read.close();

Control an Integer field Length without using Validation ??

Hi,
I have Couple of fields where I need to configure them as Integers.
Now each one has a fixed length that i need to limit to.
But when i create a field of type: integer, i cannot select teh length!!!
To achive this the idea i have is to write a validation which checks length..
But can i achive it without going for a validation on each field???
PS: I am aware that TEXT field can limit the length But it also allows me to enter text values, my requirement clearly says that to allow users to only enter Numeric values..
Did anyone face a similar Case?

Hi Eva,
I didn't try in the system, but I feel there are two solutions to achieve your requirement (*of course in both cases you will need to write a simple validation)
Solution 1 : When field is defined as "Integer" in Console.
lets take an example, you want to restrict an integer field with a limit of max 4 characters.
Maximum value of a 4 character integer can be "9999". So, you can put a simple validation to compare the field value with 9999. if the value is less then this means fields values is less than 4 characters, else more than 5 characters.
In this case Your validation expression in expression editor will be:
FIELD NAME<= "9999"
Solution 2 : When field is defined as "Text" in Console.
In this case you can restrict the maximum field length through Console. But you will also need to write a validation to ensure that user is not entering any alphabets or special characters in this field.
In this Case you can use below validation:
HAS_ALL_CHARS(FIELD NAME, "0","9")
This will ensure that field has all characters between 0 and 9 and doesn't hold any special character or alphabets.
In Both cases you will need to set "Automatic Execution" property as "Error". Also please do not manually type any function or value in expression editor. use drop down for fields, operators, functions etc. and enter numeric values using the first blank box before dimension list.
Kindly revert if you face any issues.

DNG SDK thinks 0xFFFFFFFF is invalid white level for 32 bit integers

As discussed in another message the DNG SDK does not seem to be able to write floating point DNGs. Since I need higher dynamic range than a 16 bit sample I instead went for 32 bit integers.
This works, and I manage to create a file but when I run dng_validate on it it says the white level is invalid. The white level I have of course set to 0xFFFFFFFF to make use of the full 32 bit range. Looking into the code in dng_ifd.cpp where this test is made it seems like the default max white level is set to 65535.0 and the file's white level is compared against that, regardless if the sample type is 16 or 32 bit. This means that I can only make use of 16 bits of the 32 bit integer which seems kind of strange. Looking into the DNG spec I don't see anything there that forbids using the full 32 bit range of 32 bit samples. So this looks like a bug to me.
This is with version 1.4
the created file can be opened in Lightroom 4, so the only problem seems to be that dng_validate does not think its valid.

Hello Charles,
I would be concerned too if my MacBook Prowas running slowly. I found a couple of articles I recommend to help isolate and troubleshoot this issue.
I recommend reviewing this article first for possible causes of the slowness:

You can further isolate the issue by determining if it is only happening in your user account or if it is happening system-wide:

Validation Rules

Hi,
I need to develop component, which can perform Validations at Objects.
External components will call it and pass it the following data:
* The object to validate
* The name of the validation rule to execute
And then my component will perform validation (on that object) through the specified validation rule.
Rule is a logical set of operations, which checks that a given data complies with specific restrictions. For example rule MinMax should check that given number is within defined range.
Rules can be anything: MinMax (for integers), StringLength, ValidMailAddress and so on.
I want my component to come with some out-of-the-box rules and I want to give the developers a good way to add rules.
Before I develop that I need to know if there is an existing tool, which provides all that (more or less).
I searched the Internet and I found only Jakarta's Validator.
Do you know some other tools?
Thanks,
T.

I want my component to come with some out-of-the-box
rules and I want to give the developers a good way to
add rules.When I saw this, I instantly thought of the W3C XML schema (Actually it's the W3C XML schema schema but I didn't go to school here.)
It has validation for all the 'normal' types you can think of and allows for custom rules using a rich set of tools (including regex.)
The (possible) downside is that you must at some point represent your data in an XML tree.

Acrobat not validating signature with three pairs of ByteRange values

I have created a PDF with a Digital signature, when opened with Acrobat Reader 10 i see the signature not bieng validated with a message saying, "There are errors in the formatting or information contained in this signature (support information: SigDict /ByteRange value)". My signature's byterange contains three pairs of integers(/ByteRange[0 569 6417 400 6817 1013]) which seems to be causing this problem. Will appreciate any input regarding this.

Hi SindhuCT,
I can't speak for PDF-XChange Viewer as to whether or not they are correctly processing the signature. The only thing I can point out is you are hashing the bytes from the beginning of the file (byte 0) to byte 569. Then you are leaving a hole for the signature from byte 570 through byte 6416. You are then hashing from byte 6417 and marching off another 400 bytes which gets you to byte 6817. Finally you are telling Acrobat/Reader to leave a hole from byte 6817 to the end of the file at byte 7830. The problem is your got byte 6817 on both sides of the fence, as part of the signed data and as part of the second unsigned portion of the file. That's probably where your problem lies.
Yes, the PDF specification does say you can include other ranges, but it also says that it's not recommended because you are not going to be checking for all changes to the document. The specification says you should sign the entire file, less the hole for the signature contents.

[JS][CS3] Validating edittexts in ScriptUI

Hi,
I have to attach validation methods to a bunch of edit fields' onChange. Some fields would have to contain floats (toFixed(2)), some - integers, some - capitalized strings after the field has lost focus. I'm ready with 3 functions to be attached to controls, but I would like to hear the most robust solution to this problem. Would you use ctrl.onChange = fn, or rather ctrl.addEventListener()...?
Any comments welcome.
M.

Wait a second... Something I hadn't considered before.
The problem of relying on the onChange event of a single field is that a click in an OK button will still close the window.
But, if you set an event listener to the OK button's click event, you can validate all fields and then cancel the event.
Here's an example that does work in ESTK2 (CS3) (I think this code will paste and show correctly, if it doesn't, sorry)
// Basic ScriptUI validation
/* This script shows the basics of validation using ScriptUI events
By using the "change" event, a script can be notified that a value has changed. The problem with this approach is that it
requires a field to lose focus for the event to fire. For example, a user can type an invalid number in a field, then, without leaving
the field, click the OK button (which is still enabled because validation has not happened on the invalid field yet). In this case, clicking
the OK button causes the field to lose focus, the validation occurs, but the OK button has already been pressed, and the dialog will
close with an invalid entry.
We could use the "changing" event that fires for every character typed; but, that approach brings its own set of complications. For example, the
user is typing "12 inches" in the field. If the validation routine accepts units and abbreviations, as the user types we get the following states:
"1" - valid
"2" - valid
" " - valid
"i" - INVALID
"n" - valid
"c" - INVALID
"h" - valid
"e" - INVALID
"s" - valid
That doesn't work.
If we intercept the OK button's mouseDown event, we can validate all fields, and either allow the OK button click event or cancel it.
If cancelled, the OK button can disabled, and a visual cue could be provided as to the offending field(s).
With this approach, the valdiation routines need to have a reference to the OK button, and all registered validations
must happen each time a field is edited to set the state of the OK button.
// setControlState sets the background color of a control to "good" or "bad". The white for good, red for bad
setControlState= function( myControl ) {
if ( myControl.isValid ) { // we're good, make it white
myControl.graphics.backgroundColor = myControl.graphics.newBrush( myControl.graphics.BrushType.SOLID_COLOR, [1,1,1,1] );
} else { // we're bad, make the field background red (straight red, [ 1, 0, 0, 1] is a bit harsh, so we're using a red-ish color
var myRedColorArray = [ 210/255, 12/255, 82/255, 1];
myControl.graphics.backgroundColor = myControl.graphics.newBrush( myControl.graphics.BrushType.SOLID_COLOR, myRedColorArray );
// validateInteger will ensure that a field contains a valid integer
validateInteger = function( myEvent ) {
myEvent is passed to the handler when the event fires, myEvent.target is the target control of the event.
We're adding a property "isValid" to the control so we can quickly check the state of any control
Note that parseInt parses "12x" as 12, so you can't just check for isNaN on a parseInt...
// make this a required field by checking to see if there's anything there
if ( myEvent.target.text.length == 0 ) {
myEvent.target.isValid = false;
} else if ( isNaN( Number( myEvent.target.text ) ) ) { // if it can't be cast to a number, it's obviously bad
myEvent.target.isValid = false;
} else {
// if we can parseIn the content of the field, change it back to a string, and get the original value, the original value must have been a string
myEvent.target.isValid = ( parseInt( myEvent.target.text ).toString() == myEvent.target.text );
// set the control's background to red if it's invalid
setControlState( myEvent.target );
// check all the fields, and set the OK button state
validateAll( myEvent.target.window.okButton );
// validateReal will ensure a field has a valid Real number
validateReal = function( myEvent ) {
// make this a required field by checking to see if there's anything there
if ( myEvent.target.text.length == 0 ) {
myEvent.target.isValid = false;
} else if ( isNaN( Number( myEvent.target.text ) ) ) { // if casting to a number is NaN, it's bad...
myEvent.target.isValid = false;
} else {
// if user enters ".2", parseFloat turns it into "0.2" so the same parseFloat().toString() won't work like it does for integers
// using a regex instead
var regex = /\d*\.{0,1}\d*/g; // zero or more digits, possibly a decimal point, followed by zero or more digits
// if the first element of the array returned from String.match equals the original, we're good
try {
myEvent.target.isValid = ( myEvent.target.text == myEvent.target.text.match( regex )[ 0 ] );
} catch( e ) {
myEvent.targetisValid = false;
//set the control's background to red if it's invalid
setControlState( myEvent.target );
// now check all the fields
validateAll( myEvent.target.window.okButton );
// uses the UnitValue object to ensure whatever is typed in will be a valid measurement unit
// for this handler, we wil set a "fieldUnit" property on the edit box, all units will be converted to those units
// we're supporting all units that UnitValue supports except pixels and percents as they are based on a base unit and traditional points/picas as no one will likely enter "tpc" or "tpt" vs "pt" or "pc"

// no empty fields

var regex = /\d*\.{0,1}\d*/g; // zero or more digits, possibly a decimal point, followed by zero or more digits
// if the first element of the array returned from String.match equals the original, there's no units

Validating in a DataGrid

I use a TextInput ItemEditor in a Datagrid. How do I make
sure the user only inputs numeric input? I can use restrict to get
only integers, but what if I want real numbers with two decimal
places?

A simple solution would be to use a Number Validator as seen

Struts validation

Hi
i have a question and was looking forward for your help...
during struts validation we use depends="int"
so our purpose is to accept values which are pure integers and remaing should be rejected by validator.....but then if we put some text say "abc" it simply gets converted to 0 and validator accepts it and shows no error
So how can validator classes help us to get around this....that is when ever user inserts something that's not a proper number validator should alarm with an error

I've found a solution that works for me:
1. In the form in each jsp of the multi-page form, add:
<netui:hidden dataSource="{actionForm.page}"/>
2. Add a page="<pageno>" attribute to each field element in the validations xml
file, where validation is performed when <pageno> is <= to the current page number.
3. In each action method add:
form.setPage(<pageno>)
where <pageno> is appropriate to the page that this action will forward to. You
will need to initialise page to 1 in the begin() method.

Powershell script error adding integers

Hi All, I am trying to add integers but the script is not running. I am using variable "a" with the same line of thinking as
$arg in $args
$a in $as
# create a script thats adds numbers using foreach
# put an if statement if the numbers are not valid
My script begins here:
   set-psdebug -strict
    $total = 0
foreach($a in $as)
               if ( $a -as[int] -eq $null)
            { Write-host "this is not a valid number"
                exit 1
      $total += $a
Write-host "The total is $total"
I am calling my script with the following line: .\finalexam\foreachadd.ps1 6 6 i
The error is :
The variable '$as' cannot be retrieved because it has not been set.
At C:\cmd.practise\finalexam\foreachadd.ps1:8 char:15
+ foreach($a in $as)
+               ~~~

You need to go back and study the very initial basics of PowerShell. You are repeatedly guessing wrong and misunderstanding how this works. Without the fundamentals you will be forever lost.
Try to understand why and how the following works. Read the basics of using PowerShell variables and loops.
$as=1,2,'x',4,5,'z'
$total=0
foreach($a in $as){
if($a -as [int]){
        $total+=$a
}else{
        Write-host "$a cannot be converted to a valid integer 32"
Write-host "The total is $total"
You also need to learn how to format your code. Tat would make it easier for you too see your mistakes.

Range Validation in Java

Hi,
I am having a doubt in Range Validation
I having the following as input, i will maintain a Default Values,
StartId, EndId as Constant in my program
Example :
StartID= "0000000" Format will be "XXXXXXX"
EndID = "0000100" Format will be "XXXXXXX"
From the UI, i will have the option to enter a text. If the User has to enter the same Format "XXXXXXX", the format validation I performed using reg Expression,
I need to perform the Range validation here, if the user Enters value say
"0000700" < it is not within the StartId & EndId Range, then i need to say Error.
How can i perform Range Validation in java.?
Any Ideas please..

It can be done with regexp but it's probably easier to parse the start and end ids and the entered value into integers and perform the validation using a normal if statement.
