Random Code Generation

Hi Guys,
I'm working in a Project and i need to pass a randomcode in the query string.
Need help in generating a random code with length greater than 32 and less than or equal to 255.
Thanks,
Ram.

A quick look around these forums will disclose any amount of random code ...

Urgent How to generate a random code such as registration code?

I would like to ask that how to generate a random code?
For example, when you register a E-mail account, you need to enter the code for activation. I would like to create a java Bean to do this job. Would you help me?

In fact, I would like to set a 10 digi codes randomly (such as FH654CS081, MKO624VG9f) for user input when they register the forum account. This random code will be sent to the user's email. User have to input this code to a JSP web site. Also, the code which is inputed by user will be matched with the database. If user input success, the forum account will be activated.
By generating this 10 digi codes, I want to handle this generation by using java bean.
1) Any thing else i need to import ? (such as <% page import="java.......?")
2) Any functions can handle this task?
3) Any example can be my reference?
Thank you very much

Global random integer generation in a range

Hello,
I need a way to achieve a global random integer generation in a range.
I tried FMs QF05_RANDOM_INTEGER and RANDOM_I4 without success because every time I call them from an object, always get the same number
For example, FM RANDOM_I4 with RND_MIN = 1 and RND_MAX = 5 gets RND_VALUE = 1 and FM QF05_RANDOM_INTEGER with RAN_INT_MAX = 5 and AN_INT_MIN = 1 gets RAN_INT = 3.
How can I get a global (with memory) random number generator?
Regards and thanks in advance.

Hey run the code below, it will give you different numbers.
data RAN_INT like QF00-RAN_INT.
data G_RAN_SEED like QF00-RAN_SEED.
CALL FUNCTION 'QF05_RANDOM_INTEGER'
    EXPORTING
         RAN_INT_MAX   = 5
         RAN_INT_MIN   = 1
    IMPORTING
         RAN_INT       = RAN_INT
    EXCEPTIONS
         INVALID_INPUT = 1
         OTHERS        = 2
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
write ran_int.
G_RAN_SEED = ran_int.
CALL FUNCTION 'QF05_RANDOM_SAVE_SEED'
    EXPORTING
         RAN_SEED_NEXT = G_RAN_SEED

Runtime Code Generation and operations on unknown types

(Post split in two) - Part 1
Hello,
The problem is a bit more complex so I will try to explain it as good as possible. Let's consider the following classes and interfaces (trimmed to the essential parts):
public abstract class Binding {
private String name;
public Binding(String name) {
    this.name = name;
abstract Object getValue();
// getters & setters
public interface ExpressionImpl {
public Object evaluate();
public class DirectBinding extends Binding {
private String expression;
private ExpressionImpl exprImpl;
public DirectBinding(String name, String expression) {
    super(name);
    this.expression = expression;
    this.exprImpl = /* Call to some code which will generate and load a a class that implements "ExpressionImpl" */
public Object getValue() {
    return exprImpl.evaluate();
public class RecursiveBinding extends Binding {
private String initializationExpression;
private String recursiveExpression;
private ExpressionImpl exprImpl;
public RecursiveBinding(String name, String initializationExpression, String recursiveExpression) {
    super(name);
    this.initializationExpression= initializationExpression;
    this.recursiveExpression= recursiveExpression;
    this.exprImpl = /* Call to some code which will generate and load a a class that implements "ExpressionImpl" */
public Object getValue() {
    return exprImpl.evaluate();
public class Element {
private List<Element> children;
private Element parent;
private List<Binding> bindings;
// constructor, add, remove, getters and setters
}So:
1. Element models a tree node structure (reference to children and parent) and a binding container.
2. Bindings know their parent element.
3. A Binding can search and access Bindings from it's parent element or this element's ancestors.
4. To observe that Bindings return Object values.
5. Bindings are initialized from top to bottom. So if a child element's binding requires the value of a parent element binding, this is allready available.
6. Valid expressions for DirectBindings are for example:
- "100"
- "3.5D + (new java.util.Random().nextDouble())"
- "$parent_binding + $ancestor_binding"
7. Valid expressions for RecursiveBindings are (initialization expression, recursive expression) (for a Binding called "this_binding"):
- "$parent_binding" , "$this_binding + 1"
- "100", "$this_binding * $ancestor_binding"
8. A Binding object deals with values of the same type in it's expression(s) -> only numeric, only boolean. You cannot have "$parent_binding && true" if "parent_binding" returns an Integer object (through it's "Object getValue()" method).
9. Instead of parsing and evaluating the expressions as strings, classes are generated which return the natural (Java) evaluation of the expressions. Of course valid code will be generated for the expression, so if a binding reference is found, in the generated class it will be replaced with the equivalent "binding.getValue()".

Part 2
Let's consider the following code snippet:
Element parent = new Element("parent");
parent.addBinding(new DirectBinding("parent_binding", "3.5D"); // Will call this Binding 1
Element child = new Element("child");
child.addBinding(new DirectBinding("child_direct_binding", "$parent_binding + 1"); // Will call this Binding 2
child.addBinding(new RecursiveBinding("child_recursive_binding", "10", "$child_recursive_binding + Math.PI"); // Will call this Binding 3
parent.add(child);
parent.initialize(); // this is where the code generation starts (top to bottom)Now the following classes are generated:
Binding 1 expression implementation:
public class EMC_parent_binding implements ExpressionImpl {
     public EMC_parent_binding(final BindingCache bindingCache) {
     public Object evaluate() {
          return 3.5D;
//Binding 2 expression implementation:
public class EMC_child_direct_binding implements ExpressionImpl {
     private Binding m_parent_binding;
     public EMC_child_direct_binding(final BindingCache bindingCache) {
          m_parent_binding = bindingCache.getBinding("parent_binding");
     public Object evaluate() {
          return (java.lang.Double)(m_parent_binding.getValue()) + 1;
// Binding 3 expression implementation:
public class EMC_child_recursive_binding implements ExpressionImpl {
     private boolean firstEvaluation = true;
     private Binding m_child_recursive_binding;
     public EMC_child_recursive_binding(final BindingCache bindingCache) {
          m_child_recursive_binding = bindingCache.getBinding("child_recursive_binding");
     public Object evaluate() {
          if (firstEvaluation) {
               firstEvaluation = false;
               return 10;
          } else {
               return (UnkownType)(m_child_recursive_binding.getValue()) + Math.PI; // <-------- This is where the problem appears
}Notice the casts in the evaluate() methods. Since I cannot do operations on "Object" I needed to cast to the appropriate types. This is easy to notice in Binding 2. It's easy to cast to "java.lang.Double" since when generating the code I allready have the value of "parent_binding" and thereby know it's type.
Now the problem appears at recursive bindings (code for Binding 3). The binding for which I currently generate the code has a value of "null" and cannot find an appropriate type to cast to. How can I find a type to cast to, or what other solutions do I have?
I sincerely thank you for reading this whole post, and am looking forward for some replies.
Kind regards,
Cosmin.

Error in code generation for deleting table BUT000_TD

Hi,
Did anyone encounter this error while working on EEWB ?
I created the project extension via EEWB and completed the wizard setting with the package (dev. class) value as $temp as I wanted to test it locally.
One of the errors, that I got is:

Error during distribution for compiled code generation-Reply

Hi,
Looking at your error messages, it looks as though your build is failing during the code generation phase of an autocompilation. To determine why the code generator crashed, either look in the $FORTE_ROOT/log/forte_ex*.log files or don't use autocompilation and use fcompile.
There are many reasons why the code generator could crash. Some of the things I've come across are running out of memory and trying to find invalid classes.
If its the invalid class problem you'll find a message like:
Generating code for partition BLTCustomWindow_cl0_Part1.
ERROR: Exiting due to following exception:

Integrate the changes to the workspace, start the build again and this should have cured the problem.
However, its hard to know what the cause of your problem is without seeing the output in the log files.
Good luck.

Hi,
I'm doing application distribution for my application using a fscript
script and am forcing compilation on 2 of my partitions.
This I have been doing from quite sometime successfully. Recently I
developed a new service and plugged it into my application for
deployment.
I'm successfully able to distribute & deploy the interpreted code. But
I'm getting a long list of system errors when I try doing distribution
for compiled code. And I see only one of the .exe generated instead of
two because of which I'm unable to go ahead with installaion. I would
appreciate if anybody let me know why this's happening ?. The following
is the main chunk of this error list.
Thanks in advance.

FPGA Code Generation fails with error codes 7 and -1

Hi all,
I have been having a weird issue with my LV FPGA compilation in the last couple of days, no matter what I try to compile LV fails to generate the FPGA code files and returns with errors 7 and -1 and complains that the file is not found. This happens no matter what I am trying to compile even a VI with just a while loop. I followed the discussion forum here without any luck, also followed the NI article here and that did not help either. The error codes always get generated at the start of the Generating Intermediate files step #7 (out of 7).
Attached to this post is a screenshot of the error I am getting (error -1 just says internal error and to contact NI support), bellow is basically the error I get for error code 7
An internal software error has occurred. Please contact National Instruments technical support at ni.com/support with the following information:
Error 7 occurred at Read from Text File in nirviGetInstantiation_cRIO-IDSel_Timer.vi->nirviGetInstantiation_cRIO-IDSel_Timer.vi.ProxyCaller
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS X, and / on Linux. Verify that the path is correct using the command prompt or file explorer.
=========================
NI-488: Nonexistent GPIB interface.
C:\NIFPGA\compilation\cRioController_8-SlotFPGA_FPGA-TriggerTest_C06156E2\IDSel_Timer.vhd
I tried to do some digging to see what could possibly be happening, and I noticed that LV is looking for the vhdl files in the wrong folder (see the line highlighted in red above), when generating the vhdl files, LV will place them inside the "source_files" folder under the compilation project, but for some reason it is trying to find them under the root folder not inside the source_files folder!!!
Does anyone have any idea why LV would be looking for these files in the wrong subfolder?
Thank you,
Aws

Hi Aws_Khudhair,
What version of LabVIEW are you using? And what version of the FPGA module? From what I found, it seems as though this is primarily an issue with LabVIEW 8.6 and 8.6.1.
http://digital.ni.com/public.nsf/allkb/A711119FE89E39E78625754E00075E92
This forum also discusses a similar issue:

It may also be worth repairing/reinstalling the FPGA Module and the Xilinx compile tools.

What algorithm does Excel 2010 use for Pseudo Random Number Generation (MT19937?)

Does Excel 2010+ use the Mersenne Twister (MT19937) algorithm for Pseudo Random Number Generation (PRNG), implemented by the RAND() function?
This has been a nagging question for some time now, with "hints" that it indeed does. However, a relatively thorough search turns up no definitive documentation. The most direct indication is perhaps given by Guy Melard [Ref 9] where
he tests Excel 2010's RAND() function using the Crush battery of tests in TestU01 by L'Ecuyer & Simard. Melard references a "semi-official" indication that Microsoft did indeed implement MT19937 for the RAND() function in
Excel 2010, but this reference no longer seems to be available. http://office.microsoft.com/enus/excel-help/about-solver-HP005198368.aspx?pid=CH010004571033.
The other references below [Ref 1-10] document the history of the statistical suitability of the PRNG and probability distributions in various versions of Excel. This includes the Wichmann-Hill PRNG implementations supposedly (arguably) used in
Excel 2003 & 2007 for random number generation. But still, we have no answer as to which PRNG algorithm is used in
Excel 2010 (and 2013 for that matter).
Microsoft indicates that RAND() has been improved in Excel 2010; Microsoft states, "...and the RAND function now uses a new random number algorithm." (see https://support.office.com/en-ca/article/Whats-New-Changes-made-to-Excel-functions-355d08c8-8358-4ecb-b6eb-e2e443e98aac).
But no details are given on the actual algorithm. This is critical for Monte Carlo methods and many other applications.
Any help would be much appreciated. Thanks.

I found the same KB article:
https://support.microsoft.com/en-us/kb/828795
This was introduced (according to the article) in Excel 2003. Perhaps the references in notes 2 and 3 might help.
The article describes combining the results of 3 generators, each similar to a Multiply With Carry (MWC) generator, but with zero carry. MWC generators do very well on the Diehard battery of randomness tests (mentioned in your references), and have
very long periods. But using zero carry makes no sense to me.
Combining the three generators only helps if the periods of the 3 are relatively prime (despite what the article implies). Then the period of the result will be the product of the 3 periods. But without knowing the theory behind these generators, I have
no idea what the periods would be. The formulas for MWC generators fail here.

I wish to reset my ipad. However, when I selectGeneral Reset Erase all content and Settings, I am prompted for a a Restrictions Passcode (which I have never set). I have now entered random codes 11 times and the ipad not reset. How do I get past this?

I wish to reset my ipad (as advised by the Apple Store) to attempt to resolve an issue with a non-responsive part of the screen.. However, when I select General>Reset>Erase all content and Settings, I am prompted for a a Restrictions Passcode (which I have never set). I have now entered random codes 11 times and the ipad has not reset. How do I get past this? I am now at the point where I have to wait 60 mins before I can enter another random passcode. I just want the ipad to clear down, erase everything so I can start again.

The other option is to force iPad into Recovery Mode.

UML & Code Generation (RAD)

Hey everyone,
I'm evaluating Java IDE's right now and I'm working with a group that uses a tool called Popkin to do their design in UML. I'm trying to find a Java IDE that can import (via XMI) those diagrams to do the code generation.
Rational and TogetherSoft have integrated environments that couple the code and design (As you code, the UML is updated and as you create UML, the code is updated, etc.)
I'm wondering though, if you use something like JBuilder, how can you import the UML from another tool? Has anyone messed with Popkin before or tried to integrate something like this?
Thanks,
Will

UML code generation

Hi,
I'm developing an application of ~50+ classes in UML on JSE8 and use java code generation.
The question is about aggregations.
Navigable aggregations translate in java code to a class attribute, and to the corresponding getter/setters-methods.
A non-navigable aggregation is not translated to java code at all.
( I would expect it should translate to an attribute, but without getter/setters.
My understanding is, "navigable" means "navigable from outside the class". Correct?)
So how can I model an aggregation, which translates to an attribute in java, without generating the getters/setters?
And where can I find a comprehensive list of how elements in class diagrams are translated to java code?
Where is the JSE8-UML-manual, which includes all these details about UML code generation?
Thanks a lot for any useful hint!

Hi,
actually, the code generator is correct.
A non-navigable association should not generate an attribute.
Consider the example:
class Order -> class Date
You have navigation from class order to class date, but not otherwise.
This means that, given a Order object, you can find it's associated Date.
However, the inverse is not true: given a Date object you have no means of "navigating" or finding out which Order objects would have that date. This is what navigation means.
This should be translated into something like this
class Order{
Date theDate;
class Date{
int day, whatever;
//no ref to order-non navigable
If navigation from both classes were possible, a much more complicated code would be needed. It would be something along these lines, considering a 1-1 association (a *-1 association would require multiple order references to be stored at Date, with yet more complications):
class Order{
Date theDate;
void setDate(Date d)
theDate=d;
d.setOrder(this);
class Date{
int day,whatever;
Order theOrder; //navigation to order
void setOrder(Order o)
theOrder=o;
Care should be taken to ensure proper consistency between references (ie: the order in date should never be changed without making a corresponding change to the new order object).
All this serves to show, you should use navigation sparringly (as needed) , otherwise you're just complicating your code more than you should.

Mappings code generation : regular SQL / cursor PL/SQL

Hi,
When designing mappings, I fear that code generation can be potentially dangerous, because OWB automatically chooses the best method to generate the code (regular SQL or PL/SQL).
I am looking for some examples where code generation for a mapping:
- gives a regular SQL statement
- gives a cursor-based PL/SQL
- a small change in a mapping makes a regular SQL mapping to be transformed in a cursor-based PL/SQL
Thank you
Alexandre

I have not said that different modes executes at the same way what the use to have different options if they actually mean the same, right? I have said that they produced the same result i.e. if you expect the mapping to insert 1000 rows from the source to the target it will be done no matter which operation mode you choose.
But by different ways. To keep it simple lets say that:
set base mode will result in:
insert into target ()
select from source;
row based will result in:
begin
for a in (select * from source) loop
insert into target
end loop;
end;
Now lets assume that 5 rows from those 1000 you are going to insert, will break some NOT NULL constraint at the target.
If you choose Set-base mode entire insert from select will fail resulting no rows is inserted into target. Audit trail will contain message like constraint violated and thats it. You will have to find bad records by yourself.
If you choose Row-base mode 995 rows will be inserted (depending on mapping configuration) into the target and 5 will be listed in audit trail with the same constraint violated message.
Thats why default operating mode is Set based fail over to Row based. That means OWB will try to execute mapping in the fastest way set based, but if it fail, it will try again to accomplish the task by running in row base mode, providing complete audit trail fro bad rows.

Enhanced Flash Builder Code Generation Functionality

For voting in JIRA:
https://bugs.adobe.com/jira/browse/FB-27169
The code generation feature FB 4 currently has is only really useful for quick throwaway prototyping or very simple forms. The generation should allow you to configure formatting via default templates, AND optionally utilize a dialog box (similar to that used in refactoring but with a few extras) so that you can configure the contents of each generated function and provide appropriate function names according to coding best practices. For example:
-User initiates event handler generation
(Optional, if Codegen dialog is enabled)
-User is prompted with a dialog that allows them to customize the generated function name, and possibly specify whether they need an Event parameter passed to the function. (Default to NO event parameter, but this could be a pre-configured user option.)
-FB utilizes the customized code generation format (customizable by the developer) to generate the new function
If you need a "submitForm()" function and you want both a TextInput's enter action and a button's click action to call it, currently you're better off typing it all yourself, because auto-generation is going to put this long-named function that assumes you need 'event' passed to it. An event:MouseEvent parameter just gets in the way when you also want a TextInput's enter event to call that function, for example. Or perhaps we want to provide a more descriptive name to each handler (via dialog) without assigning IDs to each and every component: "datagrid1_changeHandler" or "button1_changeHandler" doesn't tell us what the function actually does. It's a basic coding best practice to name functions or methods after the actions they actually perform, and in a large application with complex forms auto-generated generic sounding function names are essentially useless from a maintainability standpoint.

For anyone interested, I figured it out:
to generate a CFC, you have to right-click a table in the RDS Dataview, then you can generate a CFC. You cannot generate a CFC from an AS class as described in the CF Builder help within Flash Builder.
Adobe: it would be nice if this got fixed – and if someone there replied to posts like this. You do know all this, don‘t you?
