Strange Stack Overflow Error in Sudoko Backtracker
(Disclaimer: There are maybe 20 different versions of this question on SO,
but a reading through most of them still hasn't solved my issue)
Hello all, (relatively) beginner programmer here. So I've been trying to
build a Sudoku backtracker that will fill in an incomplete puzzle. It
seems to works perfectly well even when 1-3 rows are completely empty
(i.e. filled in with 0's), but when more boxes start emptying
(specifically around the 7-8 column in the fourth row, where I stopped
writing in numbers) I get a Stack Overflow Error. Here's the code:
import java.util.ArrayList;
import java.util.HashSet;
public class Sudoku
{
public static int[][] puzzle = new int[9][9];
public static int filledIn = 0;
public static ArrayList<Integer> blankBoxes = new ArrayList<Integer>();
public static int currentIndex = 0;
public static int runs = 0;
/**
* Main method.
*/
public static void main(String args[])
{
//Manual input of the numbers
int[] completedNumbers = {0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,3,4,
8,9,1,2,3,4,5,6,7,
3,4,5,6,7,8,9,1,2,
6,7,8,9,1,2,3,4,5,
9,1,2,3,4,5,6,7,8};
//Adds the numbers manually to the puzzle array
ArrayList<Integer> completeArray = new ArrayList<>();
for(Integer number : completedNumbers) {
completeArray.add(number);
}
int counter = 0;
for(int i = 0; i < 9; i++) {
for(int j = 0; j < 9; j++) {
puzzle[i][j] = completeArray.get(counter);
counter++;
}
}
//Adds all the blank boxes to an ArrayList.
//The index is stored as 10*i + j, which can be retrieved
// via modulo and integer division.
boolean containsEmpty = false;
for(int i = 0; i < 9; i++) {
for(int j = 0; j < 9; j++) {
if(puzzle[i][j] == 0) {
blankBoxes.add(10*i + j);
containsEmpty = true;
}
}
}
filler(blankBoxes.get(currentIndex));
}
/**

* duplicate, via a (relatively inefficient) sort.

*/
public static boolean checkDupl(int[] testArray) {
for(int i = 0; i < 8; i++) {
int num = testArray[i];
for(int j = i + 1; j < 9; j++) {
if(num == testArray[j] && num != 0) {
return false;
}
}
}
return true;
}
/**
* If the puzzle is not full, the filler will be run. The filler is my
attempt at a backtracker.
* It stores every (i,j) for which puzzle[i][j] == 0. It then adds 1
to it's value. If the value
* is already somewhere else, it adds another 1. If it is 9, and
that's already there, it loops to
* 0, and the index beforehand is rechecked.
*/
public static void filler(int indexOfBlank) {
//If the current index is equal to the size of blankBoxes, meaning
that we
//went through every index of blankBoxes, meaning the puzzle is
full and correct.
runs++;
if(currentIndex == blankBoxes.size()) {
System.out.println("The puzzle is full!" + "\n");
for(int i = 0; i < 9; i++) {
System.out.println();
for(int j = 0; j < 9; j++) {
System.out.print(puzzle[i][j]);
}
}
System.out.println("\n" + "The filler method was run " + runs
+ " times");
return;
}
//Assuming the puzzle isn't full, find the row/column of the
blankBoxes index.
int row = blankBoxes.get(currentIndex) / 10;
int column = blankBoxes.get(currentIndex) % 10;
//Adds one to the value of that box.
puzzle[row][column] = (puzzle[row][column] + 1);
//Just used as a breakpoint for a debugger.
if(row == 4 && column == 4){
int x = 0;
}
//If the value is 10, meaning it went through all the possible
values:
if(puzzle[row][column] == 10) {
//Do filler() on the previous box
puzzle[row][column] = 0;
currentIndex--;
filler(currentIndex);
}
//If the number is 1-9, but there are duplicates:
else if(!(checkSingleRow(row) && checkSingleColumn(column) &&
checkSingleBox(row, column))) {
//Do filler() on the same box.
filler(currentIndex);
}
//If the number is 1-9, and there is no duplicate:

filler(currentIndex);
}
}
/**

called by the

public static boolean checkSingleRow(int row) {
return checkDupl(puzzle[row]);
}
/**
* Used to check if a single column has any duplicates or not.
* filler method, as well as the checkColumns of the checker.
* @param column

*/
public static boolean checkSingleColumn(int column) {
int[] singleColumn = new int[9];
for(int i = 0; i < 9; i++) {
singleColumn[i] = puzzle[i][column];
}
return checkDupl(singleColumn);
}
public static boolean checkSingleBox(int row, int column) {
//Makes row and column be the first row and the first column of
the box in which
//this specific cell appears. So, for example, the box at
puzzle[3][7] will iterate
//through a box from rows 3-6 and columns 6-9 (exclusive).
row = (row / 3) * 3;
column = (column / 3) * 3;
//Iterates through the box
int[] newBox = new int[9];
int counter = 0;
for(int i = row; i < row + 3; i++) {
for(int j = row; j < row + 3; j++) {
newBox[counter] = puzzle[i][j];
counter++;
}
}
return checkDupl(newBox);
}
}
Why am I calling it a weird error? A few reasons:
The box that the error occurs on changes randomly (give or take a box).
The actual line of code that the error occurs on changes randomly (it
seems to always happen in the filler method, but that's probably just
because that's the biggest one.
Different compilers have different errors in different boxes (probably
related to 1)
What I assume is that I just wrote inefficient code, so though it's not an
actual infinite recursion, it's bad enough to call a Stack Overflow Error.
But if anyone that sees a glaring issue, I'd love to hear it. Thanks!

Printed page information within PDF file
Printed page information within PDF file
I just opened my PDF file using the default PDF reader on Ubuntu, and when
I tried to print it, the "Pages" box was already filled with "108-115". I
was surprised, because that's the page number that I printed from this
file last time, which was many days ago!
I wonder where the "last printed page information" is stored. Is it in the
PDF file itself, or is it somewhere else in the computer?

How do you add mysql-connector-java-5.1.26 to Eclipse Android Developer Tools
How do you add mysql-connector-java-5.1.26 to Eclipse Android Developer Tools
I want the following line of code to work in Eclipse Java but apparently I
need to import/add mysql-connector-java-5.1.26 to my eclipse android
project so I can send a mySQL query via an android device.
Class.forName("com.mysql.jdbc.Driver");
How can I add the mySQL library to a current project? I've seen other
tutorials about doing this here at stack overflow but they've been kind of
unspecific and just say "just ADD it to your current project" but that's
where I'm stumped.
Most tutorials online just tell you how to start a new project from
scratch, but I'm working with an android application.
Do I go to File>Import? and then select the .zip with the mySQL files? Or
do I select the folder or something? I'm doing this on a Mac.
Thanks.

How to add two UITableViews to ViewController in storyboard?
In my app, I want to handle 2 tables in one ViewController.
First I drag a UITableViewController into NavigationController, so there
is already a UITableView.
Then I drag another UITableView to the scene, but the second UITableView
can't be placed at the same level as first UITableView, it can only be a

structs, please help.

What is best Ruby Class design / pattern for this scenario?
I currently have this class for scraping products from a single retailer
website using Nokogiri. XPath, CSS path details are stored in MySQL.
ActiveRecord::Base.establish_connection(
:adapter => "mysql2",
...
)
class Site < ActiveRecord::Base
has_many :site_details
def create_product_links
# http://www.example.com
p = Nokogiri::HTML(open(url))
p.xpath(total_products_path).each {|lnk|
SiteDetail.find_or_create_by(url: url + "/" + lnk['href'], site_id:
self.id)}
end
end
class SiteDetail < ActiveRecord::Base
belongs_to :site
def get_product_data
# http://www.example.com
p = Nokogiri::HTML(open(url))
title = p.css(site.title_path).text
price = p.css(site.price_path).text
description = p.css(site.description_path).text
update_attributes!(title: title, price: price, description: description)
end
end
I will be adding more sites (around 700) in the future. Each site have a
different page structure. So get_product_data method cannot be used as is.
I may have to use case or if statement to jump and execute relevant code.
Soon this class becomes quite chunky and ugly (700 retailers).

Why do we need to create android service
Why do we need to create android service
This is very basic question but I am unable to figure it out because as I
read that Service runs on main thread. So why do we need to create a
Service? and because for intense CPU task we need to create Async task or
thread in Service then why don't we create them in activity or application
class?
I wanted to create a service which will continuously perform a set of task
when it is started. I can't find any method in Service which will run in
loop. Is there is such method? or do I have to create a thread in service
to set a loop?

Most effecient way to migrate related tables from one Microsoft Access Web App to another?
Most effecient way to migrate related tables from one Microsoft Access Web
App to another?
I've got two Microsoft Access 2013 Web Apps, hosted in SharePoint 2013 as
part of Microsoft Office365. Both databases contain roughly the same
tables and structure (with some minor tweaks).
We have two databases because our particular SharePoint server encountered
a fluke error and irreparably corrupted the UI for the first Access Web
App. In the end it was more cost-effective to just build a second Access
Web App from scratch, rather then try to reverse the corruption in the
original.
So now I have the duplicate created and functional, but I need to migrate
data. The SQL backend for the original Web App is still fully functional,
and the UI within Microsoft Access is also fully functional (it's the
SharePoint side that got broken). So with Microsoft Access 2013 and SQL
Management Studio available as my tools, what is the most efficient way to
move data from one database to another? (Excel can connect and pull data,
but can't insert records in the new database as far as I can tell, making
it relatively useless. Let me know if I'm missing something here.)
Some of the problems I run into are, I don't have owner, DBA, or SysAdmin
access to SQL - just data read and data write. I can't run any SQL queries
that alter the table, such as renaming a column or SET IDENTITY_INSERT
etc. (Was tinkering with setting the identity column, as one way of
preserving existing relationships between records.) Additionally, Access
2013 doesn't provide the full ribbon for Web Apps, but instead only
provides extremely limited functionality (screenshot below). Additionally,
the query and macro buttons do not allow you to create queries or macros
directly via code (SQL, VBA, etc.), but rather they force you to only use
the query wizard GUI and macro GUI, and they do not allow you to connect
to another database to pull data.
With these constraints, what is the best way to migrate existing data from
the first database into the second?

Adding whitespace handling to existing Java regex
Adding whitespace handling to existing Java regex
A long time ago I wrote a method called detectBadChars(String) that
inspects the String argument for instances of so-called "bad" characters.
The original list of bad characters was:
'~'
'#'
'@'
'*'
'+'
'%'
My method, which works great, is:
// Detects for the existence of bad chars in a string and returns the
// bad chars that were found.
protected String detectBadChars(String text) {
Pattern pattern = Pattern.compile("[~#@*+%]");
Matcher matcher = pattern.matcher(text);
StringBuilder violatorsBuilder = new StringBuilder();
if(matcher.find()) {
String group = matcher.group();
if (!violatorsBuilder.toString().contains(group))
violatorsBuilder.append(group);
}
return violatorsBuilder.toString();
}
The business logic has now changed, and the following are now also
considered to be bad:
Carriage returns (\r)
New lines (\n)
Tabs (\t)
Any consecutive whitespaces (" ", " ", etc.)
So I am trying to modify the regex to accomodate the new bad characters.
Changing the regex to:
Pattern pattern = Pattern.compile("[~#@*+%\n\t\r[ ]+]");
...throws exceptions. My thinking was that adding "\n\t\r" to the regex
would allot for newlines, tabs and CRs respectively. And then adding "[
]+" adds a new "class/group" consisting of whitespaces, and then
quantitfies that group as allowing 1+ of those whitespaces, effectively
taking care of consecutive whitespaces.
Where am I going awyre and what should my regex be (and why)? Thanks in
advance!

how to check if a UIViewController is in the middle of being animated on screen
how to check if a UIViewController is in the middle of being animated on
screen
Can I see somehow from, say UIViewController A, if UIViewController B is
in the middle of the animation of being presented on screen?
I know I can add code to UIViewController B (for example some boolean
value used in viewWillAppear, viewDidAppear or in the completion block of
presentViewController:animated:completion:), but I also have
UIViewController C, D, E, F etc. So I prefer to check this only in
UIViewController A if possible.
Does anyone if this can be done and in case of 'yes, it can', how..?
Thanks in advance.

Add View to Main User Control difficulty
Add View to Main User Control difficulty
Im building an extension for an app here's my problem.
There is a main Layout xaml page and this binds to the main applications
datasource(meaning you can use different layouts on the app)
I created a View that I would like to place on this layout page. My view
has its own view model which gets set once the "tool" gets clicked in the
application.
From debugging it hits my viewmodel everytime but never updates anything.
I add my view to the main layout like
<!--Begin Custom Tab Item-->
<sdk:TabItem Name="StatisticsTabItem" Cursor="Hand"
Visibility="Visible">
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="20" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<!-- Add Stats view here-->
<views:StatisticsView x:Name="StatsView"
DataContext="{Binding
BindsDirectlyToSource=True}" Grid.Row="1"/>
</Grid>
</sdk:TabItem>
So currently It sets a label on my view everytime and set its correctly
but nothing gets updated on the actual view within the main layout xaml
I did set up my label as
private string totalPop;
public string TotalPop
{
get { return totalPop; }
set
{
if (totalPop != value)
{
totalPop = value;
OnNotifyPropertyChanged("TotalPop");
}
}
}
<sdk:Label x:Name="lbltotPop" Grid.Row="1" Grid.Column="0"
Grid.ColumnSpan="2" Content="{Binding TotalPop}" />
In my other applications it works fine but dont know how to set the
binding to my view gets updated.

Using Flot with multiple with orderbars.js and categories
Using Flot with multiple with orderbars.js and categories
I am having trouble creating multiple bars with flot. There is a plugin
that can be downloaded here:
http://www.benjaminbuffet.com/public/js/jquery.flot.orderBars.js that
makes graphs with multiple bars per x category like this:
http://www.pikemere.co.uk/blog/tutorial-flot-how-to-create-bar-charts/
(see under the customized bar charts). However, his example is a bit
different in that it uses the time function rather than categories.
Here is my code:
<!doctype html>
<head>
<script language="javascript" type="text/javascript"
src="/flot/jquery.js"></script>
<script language="javascript" type="text/javascript"
src="/flot/jquery.flot.js"> </script>
<script language="javascript" type="text/javascript"
src="/flot/jquery.flot.categories.js"></script>
<script language="javascript" type="text/javascript"
src="/flot/jquery.flot.orderBars.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var data1 = [
{
label: "Male" ,
data: [["True", 1],["False", 2]] ,
bars: {
show: true,
barWidth: 0.13,
order: 1
}
},
{
label: "Female" ,
data: [["True", 3],["False", 4]],
bars: {
show: true,
barWidth: 0.13,
order: 2
}
}
];
$.plot($("#placeholder"), data1, {
xaxis: {
mode: "categories"
},
});
});
</script>
<title>Test</title>
</head>
<body>
<div id="placeholder" style="width:600px;height:300px"></div>
</body>
</html>
With the above code, the graph displays, but without any bars. If I remove
the order:1 and order:2, it displays correctly, except with the bars
overlapping each other rather than being offset by each other (I think it
just ignores the orderbars plugin).
This is a very simplified example of what I really want to do, but if
someone knows how I can get it to do what I want fairly simply, I would be
very much appreciative.
To sum up, what I want is to have two sets of two bars. The first set with
"True" under them and the second second set with "False" under them. I do
not want to use numbers to represent the values, if possible as it will
greatly complicate my more complex situation. But if I must, I would still
like to know how to do it that way.

NSObject's category is available for every NSObject subclass even without any import of this category's .h file anywhere
NSObject's category is available for every NSObject subclass even without
any import of this category's .h file anywhere
Background.
Please consider the following steps:
1) In Xcode create a new "Single View Application".
2) Create a category NSObject+Extension.h and .m files:
// .h
@interface NSObject (Extension)
- (void)someMethod;
@end
// .m
@implementation NSObject (Extension)
- (void)someMethod {
NSLog(@"someMethod was called");
}
@end
3) Ensure that NSObject+Extension.m file is included into a main target.
4) Add the following line to AppDelegate:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[NSString new] performSelector:@selector(someMethod)];
return YES;
}
5) Ensure that #import "NSObject+Extension.h line does not exists anywhere
in the app!
6) Run Application.
The output is
2013-08-27 04:12:53.642 Experimental[32263:c07] someMethod was called
Questions
I wonder if there is no any #import of this category anywhere in the app,
how is it even possible that NSString does still have NSObject+Extension
available? This behavior makes me feeling very bad about every Objective-C
category I declare because I want the categories I declare to be available
only in the scopes they are declared within. For example, I want NSObject
to be extended by Extension only in some class but not in the whole app
because its globalspace becomes "polluted" otherwise.
Is there a way to avoid this behavior? I do want my categories to work
only when I explicitly import them, not when I just have them linked to a
target I use to run.

How can I disable the automatic ReadyBoost test in Windows 7?
How can I disable the automatic ReadyBoost test in Windows 7?
Whenever I request the Properties dialog (which includes a ReadyBoost tab)
for a flash device in Windows 7, it does an automatic test to determine
whether the device is suitable for ReadyBoost.
I never want to use ReadyBoost. This is an unnecessary delay, and
potentially a cause of unnecessary writes to devices that can only take so
many writes (admittedly a lot) before they wear out.
Is it possible to disable these automatic tests, e.g. with a registry hack?

How to update values in a software from a site?
How to update values in a software from a site?
I have a project in which i have to update multiple (numerical) values in
a software.This is is similar to a Stock market trading or demat terminal.
How to they update the values of so many stocks every time they change ,
or at least a few times a second??
I tried doing the same firstly in C by using fscanf , but it took infinite
time and was very inefficient.
I also tried doing it in php but that also took a long time. Moreover in
this case and even in the previous case , it first tried to open the page
from which the values are updated, which itself took long time on slow
internet speeds.
I am planning to start the whole thing again , from scratch.
Please help me with the following
firstly , some details about how the update is performed in existing demat
trading softwares? next, which platform would be the best for the job ?
and how to do it?

Is it better to embed a view controller or add a subview?
Is it better to embed a view controller or add a subview?
For example, if I required a UITableView to appear beneath additional
content in a view, would it be best practice to either:
add a UITableView as a subview, or
add a container view holding a UITableViewController?
As far as I know, both would provide the same user experience, however I
am interested to know which method would be considered best practice?

Why is this line generated? It hurts my eyes.

Why %d is require before entering character?
Why %d is require before entering character?
I have tried following code there is require %d before entering character.
That is an after switch loop in code.
#include<stdio.h>
#include<conio.h>
void sum();
void mul();
void main()
{
char ch;
int c;
clrscr();
do
{
printf("\n\n Enetr choice ");
printf("\n\n\t 1: SUM \n\n\t 2: MUL");
scanf("\n\n\t %d",&c);
switch(c)
{
case 1:
sum();
break;
case 2:
mul();
break;
default:
printf("\n\n hhhh..... ");
}
printf("\n\n Want u calcualte again");
//scanf("%d");
scanf("%c",&ch);
printf("\n ch value is %c",ch);
}while(ch=='y'|| ch=='Y');
getch();
}
void sum()

int s;
s=10+50;
printf(" SUM: %d",s);
}
void mul()
{
int s;
s=10*50;
printf(" SUM: %d",s);
}
Here in this code after switch I tried to input character but without the
scanf statement which is in comment is require while you input character.
without that scanf statement compiler does not take character input. so
please give me solution.

How to get a timestamp that is guaranteed to differ every time it's fetched?
How to get a timestamp that is guaranteed to differ every time it's fetched?
To generate global unique ids, I need something like a timestamp of their
creation. But those ids can be generate directly after each other in
source code. So the time with milliseconds isn't accurate enough and could
unintentionally produce equal ids.
Thefore I need a timestamp exact enough that it differs every time it is
fetched. I though about CPU cycles, but I don't know if there is a way to
get this information.

Refactor an MVC app to use the Command pattern
Refactor an MVC app to use the Command pattern
I have an MVC based application that I need to refactor to add support for
multiple levels of undo/redo. I have settled on the Command Pattern to
provide this functionality.
The application in question has functionality that adds/removes items
to/from a model. The controller provides these via methods like add_item,
remove_item etc. The implementation in the model provides the actual
implementation of the stack.
This functionality now needs to go into commands like, an AddItemCommand,
seen below.
class AddItemCommand
def execute(event)
self.item = event.item
model.add(self.item)
end
def unexecute()
model.remove(self.item)
end
end
Here an event object is provided to the command on execute, which contains
the item to be added to the model. In unexecute this item is removed from
the model. I'm glossing of over some details that aren't relevant to the
question.
What is a good way to get access to said model object from inside the
command instance?
Previously the model object was an instance present on the Controller so
the add_item method could just use self.model.add_item. But now it needs a
way to get to this model.
The model isn't a singleton but it is singular in that, there aren't
multiple instance of it. The items are added to the same instance. Should
I get a reference to a singleton of the model in the command's
execute/unexecute methods?
The textbook implementations I have seen suggest passing in the model to
the command's constructor when creating it like so,
def initialize(model)
self.model = model
end
// at instatiation
cmd = new AddItemCommand(model)
commands.add(cmd)
The drawback I see with is that I need the ability to add the command
lazily. ie:- The command is only added and executed when a corresponding
event is fired. I can maintain a mapping of events to commands to make
this happen. But I lose this flexibility when the command needs to
constructed with the model upfront.
What would be a good way to achieve flexibility to allow commands to get
at the model(s) without loosing the ability to add them lazily?
Thanks.

xcode: Mysql connector library not work on iphone5 (armv7s) ,any solution?
I built my App using Mysql Connector/C to connect a remote Mysql database,
its works fine on the simulator (no errors, no warnings) but when i try to
run it on my device (iphone5) i got this error:
No architectures to compile for (ARCHS=armv7 armv7s, VALID_ARCHS=armv7
armv7s)
i tried -as in some answers- to change setting (Architectures - Build
Active Architectures- Valid Architectures) but the error still, only when
i change the setting (Architectures & Valid Architectures) to "armv6" its
build without error but many warnings appears says:
warning: no rule to process file '(my App dir)/main.m' of type
sourcecode.c.objc for architecture armv6
and also for all .m files, when i tried to start the App i got message:
Xcode cannot run using selected device
I know that the Connector library need to update , but are there any
solution ?

Where is guest ring-3 code run in VM environment?
Where is guest ring-3 code run in VM environment?
According to the white paper that VMWare has published, binary translation
techinology is only used in kernel (ring 0 codes), ring 3 code is
"directly executed" on cpu hardware.
As I observed, no matter how many processes are run in the guest OS, there
is always only 1 process in the host OS. So I assume all the guest ring 3
code are run in the single host process context. (for VMWare, it's
vmware-vmx.exe).
So my question here is, how do you execute so many ring 3 code natively in
a single process? Considering most of the windows exe file don't contain
relocation information, it cannot be executed somewhere else, and binary
translation is not used in ring3 code.
Thanks.

HTML 5 drag and drop to exact position
HTML 5 drag and drop to exact position
I want my element that I am dragging to drop into exactly the position it
was released. I'm not sure if I'm doing this right. So far I'm get the
drop coordinates in the drop event and then setting the top and left
properties. It works, sort of, except I have to offset the left and top
which makes me suspect there is something not right. Here is my function.
Can anyone point me in the right direction
var dropped = function (e) { cancel(e);
machine.parentNode.removeChild(machine);
e.target.appendChild(machine);
$(machine).css("top", (e.offsetY - 40) + 'px');
$(machine).css("left", (e.offsetX - 30) + 'px');
$("#text").html(e.offsetX + ' - ' + e.offsetY);
return false;
}
I want my element that I am dragging to drop into exactly the position it
was released. I'm not sure if I'm doing this right. So far I'm get the
drop coordinates in the drop event and then setting the top and left
properties. It works, sort of, except I have to offset the left and top
which makes me suspect there is something not right. Here is my function.
Can anyone point me in the right direction

Log in with cURL and echo response with cookie
Log in with cURL and echo response with cookie
I am trying to write an "auto-login" script, that uses curl to log in to a
specific site and then echoing the response, so that the user can "bypass"
the login. (For example, to grant one-time logins etc)
Obviously, using the following method, the cookie is stored on the server,
not on the client, in cookie.txt.
I've tried setting $_COOKIE, but that won't work, since the URLs (actually
subdomains) of the auto-login script and the service to be logged into,
are different.
Login works fine. You see the screen as if you were logged in, but
clicking any link requires you to login again.
Any ideas? Thanks
The code I've used to auto-login:
<?php
$username="email@domain.com";
$password="password";
$url="http://sub.domain-to-login.com/index.php/sessions/login";
$cookie="cookie.txt";
$postdata = "email=".$username."&password=".$password.'&btn_login=Login';
$ch = curl_init();

Is it possible to add animation to a slider created by for loop?
Is it possible to add animation to a slider created by for loop?
I have create a UISlider for something like a "slider to unlock" element.
The animation I've written works well when it point to just one slider.
But I need to use a for loop to create sliders dynamically. And the
animation does not work, when I create the sliders add tags for the
sliders and add the animation function to the sliders in the for loop,
like this:
[slider addTarget:self action:@selector(UnlocklinkSlider:)
forControlEvents:UIControlEventTouchUpInside];
And the animation function is:
- (void)UnlocklinkSlider:(UISlider*)slider
{
for (int i = 0; i < rownumber; i++){
UIImageView *frontimg = (UIImageView *)[self.view
viewWithTag:i*10+1];
...
if (slider.tag==i*10) {
if(slider.value >= 0.5){
// user did not slide far enough, so return back to 0
position
[UIView beginAnimations: @"SlideCanceled" context: nil];
[UIView setAnimationDelegate: self];
[UIView setAnimationDuration: 0.35];
// use CurveEaseOut to create "spring" effect
[UIView setAnimationCurve: UIViewAnimationCurveEaseOut];
...
[UIView commitAnimations];
...
}
else{
...
}
}
}
}

Disabling default action (return false) even when action is set to .off
Disabling default action (return false) even when action is set to .off
I have a registration submit button on my website that is handled with
Jquery. The problem is that I want to prevent people from clicking on it
more than once while it is going through the process of registering their
account. For this reason I disable the click event once they have clicked
it, and do not re-enable the click unless there is an error. See bwlow
function registerClick() {
$('#register_submit').off('click',registerClick);
$.ajax( {
type: "POST",
url: "/ajax/register.ajax.php",
data: $("#register_form").serialize(),
success: function(data) {
var result = jQuery.parseJSON(data);
if (result.success) {
alert('Account registered. You are now being transferred
to Paypal for payment.');
window.location = result.success;
} else if (result.error) {
alert(result.error);
$('#register_submit').on('click',registerClick);
} else {
alert('Unhandled exception');
$('#register_submit').on('click',registerClick);
}
}
});
return false;
};
// signup
$('#register_submit').on('click',registerClick);
What unfortunately happens now is that if they double click the button,
the second click triggers the default button action which is to submit the
form to #.
I'm thinking that maybe I need to disable the button all together, but I'm
new to Jquery so this is uncharted territory for me.

ALSR and NX-bit in modern Windows?
ALSR and NX-bit in modern Windows?
How is NX-bit protection turned off when the attacker gains control over
the instruction pointer in Windows on x86-64, protected with both NX-bit
and ASLR? I'm assuming that the system call to disable this feature is
simply at a non-ASLRed address, and can be called directly?
It seems that heap spraying is frequently used to exploit modern Windows
machines (e.g. with bugs in Javascript implementations), obviously this
entails an executable heap, so how is the heap made executable prior to
the heap spray? Is there some paper that clearly shows how this is done,
on Windows?

Java - JTextArea suddenly resizes upon dialog resizing
Java - JTextArea suddenly resizes upon dialog resizing
I have a problem with using JTextArea. My actual setup is different, but
the effects remain. Here is an image of the problem:
The moment the owning JDialog resizes just 1 pixel below what the

resize. In my actual setup, they suddenly grow in height. I am using a

iOS - Using Search API for Google Shopping
iOS - Using Search API for Google Shopping
My ultimate goal is to search for an item (using a query in code) and
display some information from a JSON object using the Google Shopping API
- Objective-C Client.
I know that the search API for shopping is going to be deprecated very
shortly but wanted to at least get something to work just to show that it
does work. So short term I would like to get this to work and long term
use something similar (such as an Amazon API).
I am targeting iOS 6.0+ and am currently using XCode 4.6. I followed this
blog tutorial here for XCode 4.5 and got everything set up as stated here.
(Although maybe there is another way to get the pre-built library built -
but the blog author said that that did not work)
If you look at the first link they give you an example of how to use the
API(under Basics - Objects and Queries) but I have a problem in that I
cannot find the GTLServiceGoogleShopping object anywhere. If you use the
svn command to checkout the library files you don't get this object nor do
you get any example code for this particular service.
I am wondering if anyone has done this in iOS before and/or if anyone
would like to recommend an alternative way to do a product search on the
web that returns a JSON Object, that is compatible with XCode/iOS and that
is as easy to use as the Google Shopping API seems to be. (i.e. use a few
objects to make a http request then parse the JSON object as needed).
Any help/information/guidance would be greatly appreciated.

How to prevent copying images each time?
How to prevent copying images each time?
I have a Windows Store App with many, many images (large and small icons
in 4 scales). Simply building my app takes upwards of 5 minutes each time.
I believe it is recopying each image each time I'm building the app, even
if I've only changed a view or a code-behind. Is there a way to prevent it
from doing this? I realize it's likely repackaging the App every single
time (about a 20MB package). Hopefully there is a way to reduce this time
though.

Please explain what each technique and skill in Phantasy Star IV does
Please explain what each technique and skill in Phantasy Star IV does
I find it very difficult to remember what each technique or skill does
just by looking at its name, so I've been playing with a PDF version of
the game's manual always open on my tablet. The thing is, not every
technique and skill is explained in the manual either, like Gryz's "Crash"
skill.
Can you provide a list of every technique and skill found in the game and
its effect?
Thanks.

Does ODP.NET support EF Model-First with DbContext?
Does ODP.NET support EF Model-First with DbContext?
We're trying to use an Entity Framework Model-First approach with Oracle
11g and ODP.NET 11.2.0.3.20. We'd like to use EF 4.1 or EF 5.0 with
DbContext.
Short version: Has anyone managed to do that?
Long version: On VS2010 and Entity Framework 4.0, everything works fine.
I'm able to Generate Database from Model.
When I try it with EF 4.1 or EF 5.0, I always end up with an Object
reference not set to an instance of an Object error message in Visual
Studio:
I tried it the following ways:
Created a new EF 5.0 model in VS2012, set code generation workflow and
templates to the Oracle stuff (Generate Oracle via T4 (TPT).xaml and
SSDLToOracle.tt). Then I clicked on Generate Database from Model and chose
a working Oracle connection, but Visual Studio just shows that error.
Created an EF 4.1 model in VS2012, same error.
Created an EF 4.1 model in VS2010, same error.
Tried a Database-First approach in EF 5.0 and EF 4.1, same error.
It only works if I'm using VS2010 and EF 4.0.
However, Oracle claims that it should work, see
http://www.oracle.com/technetwork/topics/dotnet/downloads/install112030-1440546.html
:
ODAC supports DbContext APIs.

SSIS Package not wanting to fetch metadata of temporary table
SSIS Package not wanting to fetch metadata of temporary table
I have an SSIS Package, which contains multiple flows.
Each flow is responsible for creating a "staging" table, which gets filled
up after creation. These tables are global temporary tables.
I added 1 extra flow (I did not make the package) which does exactly as
stated above, for another table. However, for some reason, the package
fails intermittently on this flow, while it is exactly the same as others,
besides some table names.
The error that keeps popping up:

DB error has occurred. Error code: 0x80004005. An OLE DB record is

The database from where it has to validate the details entered by user is
NOT empty. It has the records in them. But via this query it always gives
a NullPointerException.
Please help me out.
Thanks in advance.
HTTP container java.lang.NullPointerException
I am trying to validate a user record from my database using Spring
Framework, RESTful Web Services and Jersey Implementation.
I am using MySQL v5.6.0, Eclipse Galileo, Apache tomcat v6.0
UserAccessWS.java
@Path("/user")
@Service
public class UserAccessWS {
@Autowired
private IUserService userService;
private static Logger LOGGER = Logger.getLogger(UserAccessWS.class);
@POST
@Path("/validateUser")
@Produces({ MediaType.APPLICATION_JSON })
public String getValidateUser(@Context HttpServletRequest request,
@FormParam("userName") String userName,
@FormParam("password") String password) throws JSONException {
LOGGER.info("getValidateUser method");
Users users = new Users();
users.setUserName(userName);
users.setPassword(password);
List<Users> userList = new ArrayList<Users>();
userList = userService.validateUser(users);
JSONObject userInfo = new JSONObject();
userInfo.put("authorize", true);
return userInfo.toString();
}
@POST
@Path("/login")
@Produces({ MediaType.APPLICATION_JSON })
public String userLogin(
@FormParam("userName") String userName,
@FormParam("password") String password)
throws Exception
{
LOGGER.info("in UserAccessWS::userLogin()");
JSONObject json = new JSONObject();
JSONArray jsonArr = new JSONArray();
List<Users> userList = new ArrayList<Users>();
userList = userService.userLogin(userName, password);
Null error is being pointed out in this line "userList =
userService.userLogin(userName, password);"
//System.out.println(userList);
if (userList.size() == 0)
{
json.put("status", "fail");
}
else
{
json.put("status", "success");
jsonArr.add(userList.get(0));
json.put("data", jsonArr);
}
//System.out.println(jsonArr.get(0).userId);
return json.toString();
}

Session visible on other computers?
Session visible on other computers?
I have a strange issue, where basically i have a shopping cart using a
session. When i deploy the site using IIS7 all looks fine. I add a product
to the session on one pc and it displays in my basket. When i access the
site from another pc the basket has this item in it!!??
its my understanding that a session instance is unique per user browser is
this correct? and if so, how have i managed to do this? I know its
probably something stupid but i can't figure it out, any help is much
appreciated!
My session cart code is as follows
#region Singleton Implementation
public static readonly ShoppingCart Instance;
static ShoppingCart()
{
// If the cart is not in the session, create one and put it there
// Otherwise, get it from the session
if (HttpContext.Current.Session["sCart"] == null)
{
Instance = new ShoppingCart();
Instance.Items = new List<CartItem>();
HttpContext.Current.Session["sCart"] = Instance;
}
else
{
Instance =
(ShoppingCart)HttpContext.Current.Session["sCart"];
}
}
protected ShoppingCart() { }
