#include <iostream>
#include <vector>
using namespace std;
int obtain_options( char ** optionLine)
{
vector< char*> options;
options.push_back("abc");
options.push_back("def");
std::copy(options.begin(), options.end(), const_cast< char**>(optionLine));
return options.size();
}
int main(int ac, char* av[])
{
char** optionLine;
int len;
optionLine = new char* [2];
for (int i= 0; i<2; i++)
{
optionLine[i] = new char [200];
}
for (int i=0; i<2; i++)
{
cout<<optionLine[i]<<endl;
}
for (int i=0; i<2; i++)
delete [] (optionLine[i]);
delete []optionLine;
return 0;
}
I understand there are some problems with allocating memory to optionLine in function obtain_options(), and if I change obtain_options() in this way, it will work:
int obtain_options( char ** optionLine)
{
vector< char*> options;
char *t1 = new char [100];
t1[0] = 'a';
t1[1] = 'b';
t1[2] = 'c';

t2[3] = '/0';
options.push_back(t2);
std::copy(options.begin(), options.end(), const_cast< char**>(optionLine));

I am finding the resource editor difficult to understand.
1) I create a form and place a button on it.
2) I created another form with the message "Hellow World"
3) I add an action event to the button on FORM 1 using the resource editor and netbeans opens up with a method implementing that action.
4)Now I wish to write in that method to some code to display form2 ("Hello World") . How do i do this?
Q1) How do i refer the object of form2 in this case?
Q2)Also, on the display of form2 , I wish to add a textbox on it. how do i do this using resource editor?
My basic question is how can we reference elements created by resource editor via CODE?

Currently I solve the problem like that:
JMenu menuData = new JMenu("Data");
menuData.setName("mainframe.menu.data"); // property key
localeChangedListener.add(menuData);
The LocaleChangedListener:
public class SwingLocaleChangedListener implements LocaleChangedListener {
private ArrayList<AbstractButton> abstractButtons;
@Override
public void localeChanged(ResourceBundle rb) {
logger.info("Locale changed to '" + rb.getLocale() + "'");
for (AbstractButton b : abstractButtons) {
b.setText(rb.getString(b.getName()));
}
}
public boolean add(AbstractButton b) {
initAbstractButtons();
return abstractButtons.add(b);
}
private void initAbstractButtons() {
if (abstractButtons == null) {
this.abstractButtons = new ArrayList<AbstractButton>();
}
}
}
And the registration of the Listener:
public class GuiBundleManager {
private String filePrefix = "language.lang";
private ResourceBundle rb = null;
private LocaleChangedListener listener = null;
private static GuiBundleManager instance = null;
private GuiBundleManager() {
setLocale(Locale.getDefault());
}
public String getString(String key) {
return rb.getString(key);
}
public String[] getStringArray(String key) {
return rb.getStringArray(key);
}
public Locale getLocale() {
return rb.getLocale();
}
public void setLocale(Locale l) {
rb = ResourceBundle.getBundle(filePrefix, l);
if (listener != null) {
listener.localeChanged(rb);
}
}
public LocaleChangedListener getLocaleChangedListener() {
return listener;
}
public void setLocaleChangedListener(LocaleChangedListener listener) {
this.listener = listener;
if (listener != null) {
listener.localeChanged(rb);
}
}
public static GuiBundleManager get() {
if (instance == null) {
instance = new GuiBundleManager();
}
return instance;
}
}
.
.
An other way I'm thinking of is using Component.setLocale() combined with an PropertyChangedListener:
public abstract class GUIComponentFactory {
public JLabel createLocalisedJLabel(final String key) {
final JLabel label = new JLabel(GuiBundleManager.get().getString(key));
label.addPropertyChangeListener("locale", new PropertyChangeListener() {

| java | swing | locale | null | null | 07/04/2012 11:54:12 | off topic | Java: Best way to work with Locales in Swing (with change at Runntime)?
===
I thought about the best way to implement localisation with runtime in Swing.
Currently I solve the problem like that:
JMenu menuData = new JMenu("Data");
menuData.setName("mainframe.menu.data"); // property key
localeChangedListener.add(menuData);
The LocaleChangedListener:
public class SwingLocaleChangedListener implements LocaleChangedListener {
private ArrayList<AbstractButton> abstractButtons;
@Override
public void localeChanged(ResourceBundle rb) {
logger.info("Locale changed to '" + rb.getLocale() + "'");
for (AbstractButton b : abstractButtons) {
b.setText(rb.getString(b.getName()));
}
}
public boolean add(AbstractButton b) {
initAbstractButtons();
return abstractButtons.add(b);
}
private void initAbstractButtons() {
if (abstractButtons == null) {
this.abstractButtons = new ArrayList<AbstractButton>();
}
}
}
And the registration of the Listener:
public class GuiBundleManager {
private String filePrefix = "language.lang";
private ResourceBundle rb = null;
private LocaleChangedListener listener = null;
private static GuiBundleManager instance = null;
private GuiBundleManager() {
setLocale(Locale.getDefault());
}
public String getString(String key) {
return rb.getString(key);
}
public String[] getStringArray(String key) {
return rb.getStringArray(key);
}
public Locale getLocale() {
return rb.getLocale();
}
public void setLocale(Locale l) {
rb = ResourceBundle.getBundle(filePrefix, l);
if (listener != null) {
listener.localeChanged(rb);
}
}
public LocaleChangedListener getLocaleChangedListener() {
return listener;
}
public void setLocaleChangedListener(LocaleChangedListener listener) {
this.listener = listener;
if (listener != null) {
listener.localeChanged(rb);
}
}
public static GuiBundleManager get() {
if (instance == null) {
instance = new GuiBundleManager();
}
return instance;
}
}
.
.
An other way I'm thinking of is using Component.setLocale() combined with an PropertyChangedListener:
public abstract class GUIComponentFactory {
public JLabel createLocalisedJLabel(final String key) {
final JLabel label = new JLabel(GuiBundleManager.get().getString(key));
label.addPropertyChangeListener("locale", new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent e) {
label.setText(GuiBundleManager.get().getString(key));
for(Component c : getComponents()){
c.setLocale(e.getNewValue());
}
}
});
return label;
}
.
.
.
}

Would it be better to use SQL stored procedures or something. I don't have much experience with Stored Procedures either so if that's the case I'd appreciate a good reference.
I have 2 tables - Bids, Moves
If a person creates a Move then I would like for them to be able to see Bids associated with that Move.
Right now here is the logic I am using so the User can only see their Move. FYI - I have started to integrate in Bids but unsuccessfully so please either build on existing attempt at getting bids.
public ActionResult Index()
{
if (User.Identity.IsAuthenticated)
{
MembershipUser currentUser = Membership.GetUser();
Guid currentUserId = (Guid)currentUser.ProviderUserKey;
if (currentUser != null && currentUser.ProviderUserKey != null && currentUser.IsApproved)
{
var viewModel = new HomePagingViewModel
{
Moves = moveRepo.Moves.Where(m => m.UserId == currentUserId)
.OrderByDescending(m => m.MoveId)
.Take(MovePageSize),
ClientMovePagingInfo = new PagingInfo
{
CurrentPage = 1,
ItemsPerPage = MovePageSize,
TotalItems = moveRepo.Moves.Count()
},
Bids = bidRepo.Bids.Where(b => b.UserId == currentUserId)
.OrderByDescending(b => b.BidId)
};
return View(viewModel);
}
}
return View(db.Moves.ToList());
}
public ActionResult Moves(int page = 1)
{
if (User.Identity.IsAuthenticated)
{
MembershipUser currentUser = Membership.GetUser();
Guid currentUserId = (Guid)currentUser.ProviderUserKey;
if (currentUser != null && currentUser.ProviderUserKey != null && currentUser.IsApproved)
{
var moves = db.Moves.Where(move => move.UserId == currentUserId)
.OrderByDescending(m => m.MoveId)
.Skip((page - 1) * MovePageSize)
.Take(MovePageSize);
if (Request.IsAjaxRequest())
{
return PartialView("_Moves", moves);
}
}
}
return View(db.Moves.ToList());

The parent class is QGraphicsEllipseItem. Here is the constructor; its not the final version, I will expand it when the problem is fixed:
Ellipse::Ellipse(const char* text, qreal x, qreal y, QGraphicsItem* parent, QGraphicsScene* scene) : QGraphicsEllipseItem(parent, scene)
{
this->text = new QGraphicsTextItem(text, this);
this->text->setPos(x, y);

this->setFlag(QGraphicsItem::ItemIsMovable);
this->setBrush(QBrush(Qt::white));
this->setZValue(1.0);
}
In another class I implemented a function which creates an Ellipse, puts it in the right scene and stores it in a vector to access it later.
bool GUI::createEllipse(const char* name, qreal x, qreal y, int scene)
{
if(scene == 1)
{
Ellipse* ellipse = new Ellipse(name, x, y, 0, scene_1);
//
ellipses_1->push_back(ellipse);
}
else if(scene == 2)

ellipses_2->push_back(ellipse);
}
else
return false;
gui->get().graphic_1->show();
gui->get().graphic_2->show();
return true;
}
The problem is following line "ellipse->setBrush(QBrush(Qt::red));". I don't need this line, because I set the color in the constructor. But if I delete this line, the program crashes after calling gui->show(); app->exec() does not get called. The strange thing is: When I execute this line in the else-if part, but delete it in the if part (just put away the "//" in the code above), the program runs. The Ellipses in scene_1 are then colored white, the Ellipses in scene_2 are colored red. The other way round works aswell.
But why does the program crash when I don't execute this line inside the function? I know, i can just call the function with parameter Qt::white, but i really wanna know why there is a problem. I'm using Eclipse. I already tried cleaning and rebuilding the project; it doesn't help. I hope somebody knows why this occurs. | c++ | eclipse | qt | ellipse | null | null | open | Strange QT program crash with setBrush function of QGraphicsEllipseItem

Why does the first code work but not the second when they are the same? The second was just broken down into another function.
It's supposed to not delete the string when the user inputs 'no'.
This one works. If user inputs 'no', it doesnt delete anything.

I have no trouble getting the file into an NSData object - but then I have to convert it to some Base64 String. Environment is Mac OSX, Xcode 4.3.
I have found a lot of older posting dealing with that - but the best I found was some code that made use of OpenSSL libs and where containing loads of deprecated methods.
So, my question is as follows:
Is there a better way than to use the OpenSSL libs?
If yes, do you perchance have some URL or more recent code scraps?
If no, I guess there is some project out there which deals with Base64 that can be recommended. After all Base64 is not that uncommon.

The request to the image URL will be redirected. I want to know the **end** URL. So in this case, it would be `http://i1133.photobucket.com/albums/m581/PennilessTeacher/Graphics/monster.jpg`.
I previously asked a question about fetching the status code of a cross domain image request, which seems to be impossible without a server side script doing the `http` request.
Server side scripts are out of the question here. I need the request to be processed on the client's side, as some of the sites the image element will be pointing to require some specific cookies that sit on the client side, which I obviously cannot help myself to as they're for a completely different domain. If that makes any sense...
Any client side language will do. Whether I know it or not.

' The prefix (SetACL_) can be set freely in the call to WScript.CreateObject

- After reading [this KB article][2] I added the implementation of IProvideClassInfo2, but that did not help.
- This [FAQ][3] mentions that outgoing interface should not defined as a dual interfaces. I removed the "dual" from my interface definition, but that did not help.

In VBScript I use the COM object like this:
set objSetACL = WScript.CreateObject("SetACL.SetACL", "SetACL_")
' Catch and print messages from the SetACL COM server which are passed (fired) as events.
' The name postfix of this function (MessageEvent) must be identical to the event name
' as defined by SetACL.
' The prefix (SetACL_) can be set freely in the call to WScript.CreateObject
sub SetACL_MessageEvent (Message)
WScript.Echo Message
end sub
The relevant parts of the IDL look like this:
[
object,
uuid(E1B57CA5-FD7F-4304-BC0A-8BEBDE231D53),
dual,
nonextensible,
pointer_default(unique),
helpstring("SetACL COM Interface")
]
interface ISetACLCOMServer : IDispatch
{
};
[
uuid(00D4DCD3-02B9-4A71-AB61-2283504620C8),
version(1.0),
helpstring ("SetACL Type Library")
]
library SetACLCOMLibrary
{
importlib("stdole2.tlb");
[

{
properties:
methods:
[id(1), helpstring("Receives string messages that would appear on the screen in the command line version")]
void MessageEvent([in] BSTR message);
};

]
coclass SetACLCOMServer
{

[default, source] dispinterface _ISetACLCOMServerEvents;
};
};
The **problem**: SetACL_MessageEvent never gets called.
What I have tried:
- After reading [this KB article][2] I added the implementation of IProvideClassInfo2, but that did not help.
- This [FAQ][3] mentions that outgoing interface should not defined as a dual interfaces. I removed the "dual" from my interface definition, but that did not help.

We need this pairing because we are representing an object that has levels of properties where if it is not set at one level, it uses the setting at the level above. This approach lets us record at each level what its value is and if it was set at that level or inherited.
It works great. However we can end up with literally 100,000 of these objects. And that's a ton of memory, a ton of garbage collection, etc. So, any ideas how we can somehow do this better. We looked at an array of ints and booleans with enums as the index. But that feels really awkward, which generally means more opportunities to get something wrong (ie introduce bugs).
Any suggestions?

My question concerns a VPS. I really can't wrap my head around how they work. I've been looking at a few and what I want to know is the stages involved in hosting a website with a VPS.
What I'm confused over:
1) Do I buy a domain name from 123.reg for example or via my VPS interface?
2) How to get my .html and .css and .js files onto the VPS? - is there some kind of UI provided
3) Any recommendations on a good VPS to host purely client side web pages HTML, CSS, Javascript (I'm a mac user)

Consider following class in pseudo-language:
class C {
int a;
double b;
int c;
constructor C(int value) {
this.a = value;
this.b = this.a / 10.0;
this.c = 0;
}
void say() {
print(this.b);
}
}
When going straightforward, we can express this class as struct like that (skipping error checks):
typedef struct {
int a;
double b;
int c;
} _class_C;
_class_C* _ctor_C(int value) {
this = malloc(sizeof(_class_C));
this->a = value;
this->b = this->a / 10.0;
this->c = 0;
return this;
}
void _method_C_say(_class_C *this) {
printf("%.2f", this->b);
}
void _dtor_C(_class_C *this) {
free(this);
}
This solution suffers from the promise C compilers are bound with — do not add, remove or change order of fields in struct. So despite the fact fields `a` and `c` are not used, they will bloat the code.
**How can I achieve "unordered fields" behavior?** If I had only one static `C`, it could be written as follows:
int _staticfield_C_a;
double _staticfield_C_b;
int _staticfield_C_c;
void _ctor_C(int value) {
_staticfield_C_a = value;
_staticfield_C_b = _staticfield_C_a / 10.0;
_staticfield_C_c = 0;
}
void _staticmethod_C_say() {
printf("%.2f", _staticfield_C_b);
}
so compiler can optimize out redundant or unused fields up to sole `_staticfield_C_b`, but what solution should I use when `C` can be instantiated in dynamic, and I don't mind the order of fields, memory layout and code human-readability at all? | c | optimization | data-structures | struct | null | null | open | Forcing unordered struct fields in C

My purpose is to understand how Scala treats package statements, written in the Java style. To this end, I wrote up a little example class (that I named DinnerTimeP.scala as below:
package dinnertime
class Dinner {
val veggie = "broccoli"
def announceDinner(veggie: String) {
println("Dinner happens to be tasteless " + veggie + " soup")
}
}
I have a folder called scaladev, under which I have created the package folder, dinnertime. Under this package lives DinnerTimeP.scala. On the DOS command I then navigate to dinnertime and compile the file DinnerTimeP (the name sounds silly) with scalac as below.
C:\scala-2.9.1.final\scala-2.9.1.final\scaladev\dinnertime>set CLASSPATH=.;C:\scala- 2.9.1.final\scala-2.9.1.final\scaladev
C:\scala-2.9.1.final\scala-2.9.1.final\scaladev\dinnertime>scalac DinnerTimeP.scala
I was hoping to find Dinner.class generated right under the dinnertime folder and sitting next to the source file DinnerTimeP.scala.
To confirm my understanding, I created a HelloWorld.java program under the same folder:
package dinnertime;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
I compiled HelloWorld.java on the command line as follows:
C:\scala-2.9.1.final\scala-2.9.1.final\scaladev\dinnertime>javac HelloWorld.java
The HelloWorld.class file was generated right next to its source file.
This was the exact situation I wanted to see with the Scala source file and its compiled file.
Instead I see a new package folder generated by Scala inside the package folder dinnertime.
This might be naive. I am probably betraying a fundamental understanding of Scala and packages, but I was perplexed by this behaviour.
This is the problem I can't explain to myself: Why is the nested package created for the newly generated class file. This is the problem to which I which I had hoped to solve, based on my own sincere efforts
Because my experience with Scala at the present time is limited, I have resorted to asking the Scala gurus on stackoverflow to help me understand what is going on and why?
Is there a reason for this nested package to be created by Scala and not by Java?

I was able to install Magento and I am using a copy of an existing working site. The purpose is to use this new site as my dev sandbox. I am using Magento 1.11. This is also a multiple store site.
Things I have tried:
Reindex the Catalog URL Rewrite, this unfortunately never completes.
to try and solve this I have deleted all the lock files and then i have also deleted all the entries in the core_url_rewrite table.
I have also changed the Base URL in the core_config_data folder to my new url.
Thank you in advance! | magento | http-status-code-404 | null | null | null | null | open | Magento index page loads but 404 errors on all others

I use a controller action to get the pushing started; but since the pushing is often a long process (10 minutes or more), I am using spawn to fork the task. For example:
def start_pushing
spawn_block(:argv => "juggernaut-pushing") do
for x in y
Juggernaut.publish(stuff in here)
sleep(30) # delay before publishing next item
end
end
end
The problem is that I find this error in the log file when I hit the start_pushing action:
spawn> Exception in child[27898] - Redis::InheritedError: Tried to use a connection from a child process without reconnecting. You need to reconnect to Redis after forking.
So I added the following right inside the spawn_block, hoping it would fix the problem:
require 'redis'
$redis.client.disconnect
$redis = Redis.new(:host => 'localhost', :port => 6379)
It didn't seem to fix it, though the action has been working intermittently even before I added this to reset $redis. I'm thinking that perhaps resetting $redis isn't doing anything; Juggernaut is still accessing an old connection. Does that seem likely? How would I make sure that Juggernaut uses a new Redis connection?
Please let me know of any questions about what I'm describing. I appreciate the help, because I'm stuck right now. | ruby-on-rails | redis | spawn | juggernaut | null | null | open | Rails app: Reconnect juggernaut redis after forking?

Actually my requirement says that I should get/fetch information only if someone from user friend list goes offline or comes online.
What I am doing now is polling fb on regular interval of 1 min to check who is online/offline for a particular user, however this polling concept has very bad impact on performance, also after a certain number of polling request in a day(say 1 million a day) fb start throwing error.
Also, online_presence about information user's friends is not provided by fb real time update api. So can anyone please suggest a better approach to query online presence other than polling continuously.
