d13601 | train | below link will help you to understand about how android picks up layout files on various devices
http://developer.android.com/guide/practices/screens_support.html
A: Are you sure the folder name is layout-xlarge and not layout-x-large ? DOC
A: As per Android Documentation for the runtime rendering of layout
At runtime, the system ensures the best possible display on the current screen with the following procedure for any given resource:
The system uses the appropriate alternative resource
Based on the size and density of the current screen, the system uses any size- and density-specific resource provided in your application. For example, if the device has a high-density screen and the application requests a drawable resource, the system looks for a drawable resource directory that best matches the device configuration. Depending on the other alternative resources available, a resource directory with the hdpi qualifier (such as drawable-hdpi/) might be the best match, so the system uses the drawable resource from this directory.
If no matching resource is available, the system uses the default resource and scales it up or down as needed to match the current screen size and density
The "default" resources are those that are not tagged with a configuration qualifier. For example, the resources in drawable/ are the default drawable resources. The system assumes that default resources are designed for the baseline screen size and density, which is a normal screen size and a medium density. As such, the system scales default density resources up for high-density screens and down for low-density screens, as appropriate.
However, when the system is looking for a density-specific resource and does not find it in the density-specific directory, it won't always use the default resources. The system may instead use one of the other density-specific resources in order to provide better results when scaling. For example, when looking for a low-density resource and it is not available, the system prefers to scale-down the high-density version of the resource, because the system can easily scale a high-density resource down to low-density by a factor of 0.5, with fewer artifacts, compared to scaling a medium-density resource by a factor of 0.75. | unknown | |

A: In one of our projects, we have the following requirement:
*
*Create a record in DB.
*Call a service to update a related record.
*Call another service to log a ticket.
To perform this in a transactional manner, each operation is implemented as a command with undo operation. At the end of each step, the command is pushed onto a stack. If the operation fails at some step, then we pop the commands from the stack and call undo operation on each of the command popped out. The undo operation of each step is defined in that command implementation to reverse the earlier command.execute().
Hope this helps.
A: Command Patterns are used in a lot of places.
*
*Of course what you see everywhere is a very trivial example of GUI Implementation, switches. It is also used extensively is game development. With this pattern the user can configure his buttons on screen as well.
*It is used in Networking as well, if a command has to be passed to the other end.
*When the programmers want to store all the commands executed by the user, e.g. sometimes a game lets you replay the whole level.
*It is used to implement callbacks.
Here is a site which provides as example of command pattern used for callback. http://www.javaworld.com/article/2077569/core-java/java-tip-68--learn-how-to-implement-the-command-pattern-in-java.html?page=2
*Here's another link which shows command pattern with database. The code is in C#. http://www.codeproject.com/Articles/154606/Command-Pattern-at-Work-in-a-Database-Application
A: You have to define undo(), redo() operations along with execute() in Command interface itself.
example:
interface ChangeI {
enum State{ READY, DONE, UNDONE, STUCK } ;
State getState() ;
void execute() ;
void undo() ;
void redo() ;
}
Define a State in your ConcreteCommand class. Depending on current State after execute() method, you have to decide whether command should be added to Undo Stack or Redo Stack and take decision accordingly.
abstract class AbstractChange implements ChangeI {
State state = State.READY ;
public State getState() { return state ; }
public void execute() {
assert state == State.READY ;
try { doHook() ; state = State.DONE ; }
catch( Failure e ) { state = State.STUCK ; }
catch( Throwable e ) { assert false ; }
}
public void undo() {
assert state == State.DONE ; }
try { undoHook() ; state = State.UNDONE ; }
catch( Failure e ) { state = State.STUCK ; }
catch( Throwable e ) { assert false ; }
}
public void redo() {
assert state == State.UNDONE ;
try { redoHook() ; state = State.DONE ; }
catch( Failure e ) { state = State.STUCK ; }
catch( Throwable e ) { assert false ; }
}
protected abstract void doHook() throws Failure ;
protected abstract void undoHook() throws Failure ;
protected void redoHook() throws Failure { doHook() ;} ;
}
Have a look at this undo-redo command article for better understanding. | unknown | |
d13603 | train | Maybe these changes will help you:
1) Add the error message you want to show when surname is wrong:
<label for="ssurname" >Surname</label>
<input type="text" id="surname" name="surname" onblur="validateSurname('surname')" /> <br />
<span id="surnameError" style="display: none;">Please enter your surname, you can only use alphabetic characters</span>
2) Pass a string to the parameter instead of a javascript var (e.g. do validateSurname('surname') instead of validateSurname(surname)), as the function you've defined is expecting a string as a parameter.

d13604 | train | According to this docs, you can write a custom formatter to alter how the data is displayed, without altering the underlying data. Example:
function addTable(data) {
var table = new Tabulator("#table", {
height:205, // set height of table (in CSS or here), this enables the Virtual DOM and improves render speed dramatically (can be any valid css height value)
data: data.rows, //assign data to table
layout:"fitColumns", //fit columns to width of table (optional)
columns:[ //Define Table Columns
{ title: "Work Type", field: "WorkType" },

d13605 | train | This is a tricky problem! In WPF there exists the concept of a SharedSizeGroup, which allows you to share column widths across multiple grids, but this is not available in silverlight.
There are a few workarounds on the web:
http://www.scottlogic.co.uk/blog/colin/2010/11/using-a-grid-as-the-panel-for-an-itemscontrol/
http://databaseconsultinggroup.com/blog/2009/05/simulating_sharedsizegroup_in.html
Although neither are simple solutions.
You might also try Mike's AutoGrid:
http://whydoidoit.com/2010/10/06/automatic-grid-layout-for-silverlight/
A: Here is my solution using SharedSizeGroup as suggested by ColinE.
<ListBox x:Name="ResultsList">
<ListBox.Resources>
<SharedSize:SharedSizeGroup x:Key="Col1Width" />
<SharedSize:SharedSizeGroup x:Key="Col2Width" />
<SharedSize:SharedSizeGroup x:Key="Col3Width" />
<DataTemplate x:Key="ResultsListItem">
<StackPanel d:DesignWidth="385" Orientation="Horizontal">
<SharedSize:SharedSizePanel WidthGroup="{StaticResource Col1Width}">
<TextBlock x:Name="textBlock" MaxWidth="100" Text="{Binding A}"/>
</SharedSize:SharedSizePanel>
<SharedSize:SharedSizePanel WidthGroup="{StaticResource Col2Width}">
<TextBlock x:Name="textBlock1" MaxWidth="85" Text="{Binding B}"/>
</SharedSize:SharedSizePanel>
<SharedSize:SharedSizePanel WidthGroup="{StaticResource Col3Width}">
<TextBlock x:Name="textBlock2" MaxWidth="200" Text="{Binding C}"/>
</SharedSize:SharedSizePanel>
</StackPanel>
</DataTemplate>
</ListBox.Resources>
<ListBox.ItemTemplate>
<StaticResource ResourceKey="ResultsListItem"/>
</ListBox.ItemTemplate>
</ListBox>
Even the maximum with of each column can be controlled via the TextBlock's MaxWidth property. The SharedSizeGroups ensure that the TextBlocks have the same size in each row.
A: You can use WrapPanel. Set the following ItemsPanel in the Datatemple, you can just have textblock.
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<control:WrapPanel />
</ItemsPanelTemplate>
</ListBox.ItemsPanel> | unknown | |
d13606 | train | Using --module-path instead of the -classpath option for the module to be resolved for commons-math3-3.6.1.jar should work for you.

d13607 | train | I discovered that trying to migrate my own Users model to a CustomUser model is a non-trivial undertaking! I learned this from Will Vincent and his excellent post on this very topic!
Django Best Practices: Custom User Model
The Django documentation also states that migrating to the Django User in the midst of an existing project is non-trivial.
Changing to a custom user model mid-project
So, to solve my problem I started with a new empty project with only the CustomUser in my models.py as Mr. Vincent described, which worked perfectly.
After that, I setup the rest of my model classes in models.py, referencing the CustomUser model as needed.
assignee = models.ForeignKey(
to=CustomUser,
on_delete=models.RESTRICT,
blank=True,
null=True,
)
And copied the rest of my template files, view source files, static files, etc. from my original project into this new project.
My codebase is now working as expected using the Django User model.
Huge Thanks to Mr. Will Vincent's excellent article on this issue! | unknown | |
d13608 | train | if I remember correctly
'contain' => array('Entry', 'User.avatar,User.username')),
should do the trick
A: Okay, I solved it...
I just had to add the proper foreignKey to my Comment model, i.e:
var $belongsTo = array(
'Entry' => array('className' => 'Entry', 'foreignKey' => 'page_id'),
'User' => array('className' => 'User', 'foreignKey' => 'user_id'),
);
Now it finally fetches the appropriate user information! | unknown | |
d13609 | train | There is no reason for the compiler to complain. The return type
of
func throwingVoidFunction() throws { ... }
is Void and therefore the type of the expression
try? throwingVoidFunction()
is Optional<Void>, and its value is nil (== Optional<Void>.none) if an error was thrown while evaluating the expression,
and Optional<Void>.some() otherwise.
You can ignore the return value or test it against nil. An
example is given in An elegant way to ignore any errors thrown by a method:
let fileURL = URL(fileURLWithPath: "/path/to/file")
let fm = FileManager.default
try? fm.removeItem(at: fileURL) | unknown | |
d13610 | train | The reason behind your error is that the frame is None(Null). Sometimes, the first frame that is captured from the webcam is None mainly because
(1) the webcam is not ready yet ( and it takes some extra second for it to get ready)
or (2) the operating system does not allow your code to access the webcam.
In the first case, before you do anything on the frame you need to check whether the frame is valid or not :
while True:
frame = image.read()
if frame is not None: # add this line
(H, W) = frame.shape[:2]
In the other case, you need to check the camera setting in your Operating system.
Also, for capturing the webcam frames there is another method based on the VideoCapure class in Opencv that might be easier to debug. | unknown | |

Are you in a container by any chance? | unknown | |
d13614 | train | Here's a one liner to do what you want. I've tested it and it seems to be correct.
var results = source
.Publish(xs =>
xs
.Select(x =>
Observable
.Interval(TimeSpan.FromMinutes(1.0))
.Select(_ => x)
.StartWith(x))
.Switch());
Let me know if this does the trick.
A: I would wrap the observable in an observable that is guaranteed to return a value at least once per minute. The wrapper could do this by running a timer that is restarted whenever the wrapped observable returns a value.
Thus, the wrapper returns data whenever the wrapped observable returns data or when a minute has passed after the last event.
The rest of the application conveniently just observes the wrapper.
A: Here's a (non-threadsafe, in case your source is multithreaded) implementation of a RepeatAfterTimeout operator:
EDIT Updated as Timeout didn't work as I expected
// Repeats the last value emitted after a timeout
public static IObservable<TSource> RepeatAfterTimeout<TSource>(
this IObservable<TSource> source, TimeSpan timeout, IScheduler scheduler)
{
return Observable.CreateWithDisposable<TSource>(observer =>
{
var timer = new MutableDisposable();
var subscription = new MutableDisposable();
bool hasValue = false;
TSource lastValue = default(TSource);
timer.Disposable = scheduler.Schedule(recurse =>
{
if (hasValue)
{
observer.OnNext(lastValue);
}
recurse();
});
subscription.Disposable = source
.Do(value => { lastValue = value; hasValue = true; })
.Subscribe(observer);
return new CompositeDisposable(timer, subscription);
});
}
public static IObservable<TSource> RepeatAfterTimeout<TSource>(
this IObservable<TSource> source, TimeSpan timeout)
{
return source.RepeatAfterTimeout(timeout, Scheduler.TaskPool);
}
A: I had the exact same requirement once. I chose to include a default value to use if no value triggers before the first timeout. Here's the C# version:
public static IObservable<T>
AtLeastEvery<T>(this IObservable<T> source, TimeSpan timeout,
T defaultValue, IScheduler scheduler)
{
if (source == null) throw new ArgumentNullException("source");
if (scheduler == null) throw new ArgumentNullException("scheduler");
return Observable.Create<T>(obs =>
{
ulong id = 0;
var gate = new Object();
var timer = new SerialDisposable();
T lastValue = defaultValue;
Action createTimer = () =>
{
ulong startId = id;
timer.Disposable = scheduler.Schedule(timeout,
self =>
{
bool noChange;
lock (gate)
{
noChange = (id == startId);
if (noChange) obs.OnNext(lastValue);
}
//only restart if no change, otherwise
//the change restarted the timeout
if (noChange) self(timeout);
});
};
//start the first timeout
createTimer();
var subscription = source.Subscribe(
v =>
{
lock (gate)
{
id += 1;
lastValue = v;
}
obs.OnNext(v);
createTimer(); //reset the timeout
},
ex =>
{
lock (gate)
{
id += 1; //'cancel' timeout
}
obs.OnError(ex);
//do not reset the timeout, because the sequence has ended
},
() =>
{
lock (gate)
{
id += 1; //'cancel' timeout
}
obs.OnCompleted();
//do not reset the timeout, because the sequence has ended
});
return new CompositeDisposable(timer, subscription);
});
}
If you don't want to have to pass a scheduler every time, just make an overload that picks a default one and delegates to this method. I used Scheduler.ThreadPool.
This code works by using the behavior of SerialDisposable to "cancel" the previous timeout call when a new value from the source comes in. There is also a counter I use in case the timer has already elapsed (in which case Disposing the return from Schedule will not help) but the method has not yet actually run.
I investigated the possibilities of changing timeouts but did not need them for the problem I was working on. I recall that it was possible but don't have any of that code handy.
A: I think this should work the Rx way (no recursion but still involving a side effect):
public static IObservable<TSource> RepeatLastValueWhenIdle<TSource>(
this IObservable<TSource> source,
TimeSpan idleTime,
TSource defaultValue = default(TSource))
{
TSource lastValue = defaultValue;
return source
// memorize the last value on each new
.Do(ev => lastValue = ev)
// re-publish the last value on timeout
.Timeout(idleTime, Observable.Return(lastValue))
// restart waiting for a new value
.Repeat();

d13620 | train | Avoid SQL_ASCII
You should be using a server encoding of UTF8 rather than SQL_ASCII.
The documentation is quite clear about this matter, and even includes a warning to not do what you are doing. To quote (emphasis mine):
The SQL_ASCII setting behaves considerably differently from the other settings. When the server character set is SQL_ASCII, the server interprets byte values 0-127 according to the ASCII standard, while byte values 128-255 are taken as uninterpreted characters. No encoding conversion will be done when the setting is SQL_ASCII. Thus, this setting is not so much a declaration that a specific encoding is in use, as a declaration of ignorance about the encoding. In most cases, if you are working with any non-ASCII data, it is unwise to use the SQL_ASCII setting because PostgreSQL will be unable to help you by converting or validating non-ASCII characters.
Use UTF8
Use an encoding of UTF8, meaning UTF-8. This can handle the characters for any language including Chinese.
And the UTF8 encoding allows Postgres to make use of the new support for International Components for Unicode (ICU) in Postgres 10 and later.
Java also uses Unicode encoding. Just let your JDBC driver handle the marshaling of text between Java and the database. | unknown | |

A: There are many different possible causes to this problem. Two top suspects are:
*
*You are using a plug-in that is triggering a component scan of Spring classes.
*Your code has added a component scan that is hitting Spring classes.
A search for "component-scan" throughout your project can help you check for those two causes. | unknown | |
d13622 | train | It is not possible to make common code for all application. There are various type of windows application for example Database Application, Client Server Application, System Utilities, etc So, the mechanism of all applications are different then how we can define a common code template for all application. It is up to you that what you want to use Database or TcpIP Socket for your application. I know my answer is not clear. Because it is very hard to define that why we could not create scaffolding. | unknown | |

d13625 | train | The 2 easy ways to think about this are either
*
*Call the method in your class from the event handler in your form
*Have a method on your class which matches the signature of an event handler, and subscribe to the event.
The first requires no major change
private MyClass myClass = new MyClass();
public void ProgramsListbox_SelectedIndexChanged(object sender, EventArgs e)
{
myClass.DoSomething();
}
The second requires your class to have a specific method that matches the signature of that event handler currently in your form
public class MyClass
{
public void DoSomething(object sender, EventArgs e)
{
var listBox = (ListBox)sender;
// read selected index perhaps, or selected item maybe
}
}
And then in your form
private MyClass myClass = new MyClass();
protected override void OnLoad(EventArgs e)
{
this.ProgramsListBox.SelectedIndexChanged += myClass.DoSomething;
}
A: Within your Form1.cs create instance of UnIstallItem class and use it. Then on Button Click call "RemoveSelected" method of UnInstaItem class by passing programsListBox to it and it should remove the selected item.
public class Form1:Form
{
ListBox ProgramsListbox;
UninstallItem unistall;
public Form1(){
InitializeComponent();
uninstall = new UninstallItem();
button1.Click+= button1_Click;
}
void button1_Click(object sender, EventArgs e){
unistall.RemoveSelected(ProgramsListbox);
}
}
Then in your external class;
public class UninstallItem{
public UninstallItem{}
public void RemoveSelected(ListBox list)
{
if(list.SelectedIndex==-1)
{
MessageBox.Show("Please Select Item from List");
return;
}
list.Items.RemoveAt(list.SelectedIndex);
}
} | unknown | |

d13629 | train | Today, I got the same error at my project which I was working on yesterday without any problem.
Some upgrade causes this error IMO, my solution is:
*
*Open the project via Android Studio
*Open android/build.gradle and android/app/build.gradle
*Just correct things what IDE warns about, it usually warns your SDK, Kotlin and Gradle versions etc.
It's not mandatory but you can check your .bashrc exports or environment variables, sometimes it can fix some problems.
Edit: When you are updating your SDK versions, don't forget to upgrade also your project dependencies.
A: I think it depends on android emulator API level you are using.
In my case I used android emulator API 30, but compileSdkVersion was 28, so i got the error! By updating compileSdkVersion to 30, everything worked correctly!
OS: Ubuntu 20.04 LTS
Android emulator API 30
Dart 2.10.2
Flutter 1.22.2
A: Kindly check your strings.xml and It should be like:

d13631 | train | Your script could work as a CGI script, since it outputs a HTTP header, followed by the HTML content.
python -m http.server, by default, does not run CGI scripts for security, but if you add the --cgi switch, it will, provided that the scripts are in the cgi-bin directory relative to the directory you start it from.
In other words:
*
*create a cgi-bin directory
*move home.py to cgi-bin/home.py
*run python3 -m http.server --cgi 8000
*navigate to http://127.0.0.1:8000/cgi-bin/home.py
When working with CGI scripts, you might want to enable the (soon-to-be-deprecated) cgitb handler too.
Anything more intricate than that, and I would recommend looking at the Flask application framework instead, though. | unknown | |

d13633 | train | How much modification can be done to the UI that is being generated by the Swagger?
Swagger UI can be tweaked in very different ways mainly via JS or CSS.
You can have a look to https://swagger.io/docs/open-source-tools/swagger-ui/customization/overview/
Can "Try Out" functionality be modified to have more control? What I want to do is have few input fields which are not generated by swagger and use them as input for an api call, make UI more dynamic in nature.
You should have a look to the link I shared above but not sure this is doable like this.
If I had to do such kind of thing I would rather look at how to complete the original OpenAPI definition (the yaml/JSON file) before passing it to Swagger UI.
Note that there is also a "interceptor" feature in Swagger UI that allow to modify requests before sending them for instance. This might interest you.
Does the Swagger-UI depend on any sort of API gateway to make calls to api endpoints?
Not at all. Swagger UI just uses your browser to call the API at the URL documented by the OpenAPI file.
A: Stack Overflow doesn't work well when there are multiple questions as part of one "Question". Having said that, I'll answer what I know.
*
*As far as I can tell, you can modify the yaml or JSON source as much as you like. You can write an entire file from scratch, or import it from any editor.
*For this sort of testing, I think you might want to look for a more in-depth testing tool such as Postman. That's not something I have any experience with, but from what I hear it could help with "what if I send this request?" sceanrios. | unknown | |
d13634 | train | Why you want to fix the body width? simply use a container inside the body if you want like

margin: 0 auto;
}
HTML

d13635 | train | You can try using Message Queues.
Rabbit MQ is a good option as it supports MQTT (which is great for device to cloud communication) as well as AMQP (0.9.1) (which is great for cloud to cloud communication)
You can also use any standard MQTT broker (EMQTT, Mosquito, Hive etc) and implement an MQTT to MongoDB client in between. Setting the MQTT clean_session flag to false will make the broker act as a cache. | unknown | |
d13636 | train | Without changing the markup, if you set float: left to the red <div> then you could put the blue <div> to its right side
.div {
width: 100%;
height: 100px;
background-color: green;
}
.div1 {
width: 100px;
height: 100px;
background-color: red;
float: left;
}
.div2 {
width: 100px;
height: 100px;
background-color: blue;
display: inline-block;
vertical-align: top;
}
.main {
background-color: yellow;
}
<div class="main">
<div>
<div class="div"></div>
<div class="div1"></div>
</div>
<div class="div2"></div>
</div>
A: The previous solution which uses float on the red div works well, but here is another possible solution:
Apply position: relative; to the blue div (to be able to move it in relation to its default position) and add top: -100px; left: 100px; to move it up next to the red div:
.div {
width: 100%;
height: 100px;
background-color: green;
}
.div1 {
width: 100px;
height: 100px;
background-color: red;
}
.div2 {
width: 100px;
height: 100px;
background-color: blue;
position: relative;
top: -100px;
left: 100px;
}
.main {
background-color: yellow;
}
<div class="main">
<div>
<div class="div"></div>
<div class="div1"></div>
</div>
<div class="div2"></div>
</div>
A: This can also be done with the grid CSS. Here I used a named template box and then in the "chatty verbose" CSS I put the positional related for each "block". I added classes to the CSS just for clarity but you could update to your classes.
I added some color and things just for clarity and visual references but kept the "position relate" in separate CSS chunks.
.main {
font-size: 2rem;

In the Xojo IDE you could insert a Copy Files build step after the OS X build that copies your php executable into the resources folder of your built app.
Then in your App.Open you could copy that executable to wherever you want to from that SpecialFolder, or just reference it as is in your command lines depending on whether there are any restrictions imposed on how your are distributing the app (i.e. App Store).
Check out http://docs.xojo.com/index.php/SpecialFolder for some guidance on where to copy any files you need to bundle or how to reference them. | unknown | |

d13639 | train | when you put it into CURLOPT_POSTFIELDS, you're putting it into the request body, not the request URL. furthermore, when you give CURLOPT_POSTFIELDS an array, curl will encode it in multipart/form-data-format, but you need it urlencoded (which is different from multipart/form-data). remove all the POST code, and use http_build_query to build the url,
curl_setopt ( $ch, CURLOPT_URL, "https://URL.com/public/tickets.php?" . http_build_query ( array (
'PRESET' => array (
'Tickets' => array (
'name' => array (
0 => ''
),
'day' => array (
0 => '2018-03-04'

and protip, you can use parse_str() to decode urls into php arrays, and furthermore, you can use var_export to get valid php code to create that array at runtime, and finally, as shown above, you can use http_build_query to convert that array back to an url, that's what i did here. | unknown | |

d13647 | train | Silverlight is a subset of WPF. Once it was known as WPF/E (WPF everywhere). In fact, the base framework is similar, but not the same.
See this for further information: Silverlight "WPF/E" first steps: Getting started with simple analog clock, Introduction - What is WPF/E?
A: Silverlight is Microsoft’s latest development platform for building next-generation Web client applications
(WPF) is Microsoft’slatest development platform forbuilding next-generation Windows client applications
Silverlight is generally considered to be a subset of
WPF, and is a XAML
WPF is generally considered to be a subset of .NET Framework
Silverlight Support Cross OS, cross browser, cross device
WPF for Windows client users.
in order to run Silverlight applications at client machines, we need to install Silverlight
software on the client machine once
WPF, on the other hand, does notsupport any plug-in mechanism;instead, we need to install a
completed WPF client application
Silverlight applications are hosted within a webserver and a web page.
WPF applications can be deployed as standalone applications,
A: WPF is based off of the desktop CLR which is the full version of the CLR.
Silverlight is based on a much smaller and more compact CLR which provides a great experience but does not have the full breadth of CLR features. It also has a much smaller version of the BCL.
A:
Silverlight (codenamed WPF/E) is a cross-platform, cross-browser, browser plugin which contains WPF-based technology (including XAML)[17] that provides features such as video, vector graphics, and animations to multiple operating systems including Windows Vista, Windows XP, and Mac OS X, with Microsoft sanctioned 3rd party developers working ports for Linux distributions.[18] Specifically, it is currently provided as an add-on for Mozilla Firefox, Internet Explorer 6 and above, and Apple Safari. Silverlight and WPF only share the XAML presentation layer.
WIKI
A: WPF is essentially the replacement to Winforms in that it is a desktop application platform built on the .Net (3+) platform.
Silverlight represents a subset of WPF that is delivered through a browser plug-in, much like Flash/Flex.
A: Silverlight is a subset of WPF and therefore has fewer features but is more portable. WPF can be ran in both a browser or as a WinForms style application in Windows while Silverlight can only be ran in a browser. WPF is intended to run on Windows systems while Silverlight runs on Windows or Mac, also Linux via Moonlight.

d13649 | train | Your processing is very slow because you're calling autoSizeColumn for every row. From the Javadocs for the autoSizeColumn method:
This process can be relatively slow on large sheets, so this should

Place the calls to autoSizeColumn outside of the loop that creates the rows, in its own for loop only on the columns. This will minimize calls to this method and improve your performance.
A: Just for reference...
In my case, I had 1 millions plus, and the AutoSizeColumn still slow (even in the end).
So, I considerely boost the performance, just storing the column index and content length of every values (in a Dictionary), when it is large than last stored.
In the end of all process, just "foreach" the list and set the width of the column with sheet.SetColumnWidth.

A: For others encountering this issue, as @antek pointed out the files might not be accessible on a non-rooted device. You might try using an emulator running a non-Google Play API where you can obtain a root shell.
adb root
adb shell
ls /data/data/androidx.test.orchestrator/files
Alternatively, you could try running the tests using the debugger.
A: I could not find the text file, but I was able to get logcat and view the fatal that caused the orchestrator to crash
first I clear the logcat
adb logcat -c
then I run the test, then I grab the logcat
adb logcat > ~/Desktop/logcat
then I open logcat file and search for string FATAL
A: If you are working with an emulator, in A.S open Device File Explorer and go to:
/data/user_de/0/android.support.test.orchestrator/files/, then you can look for a particular file there

d13654 | train | I found out where to add a pre-receive or post-receive hook on a repository basis by adding a file to the Bitbucket server. In the Atlassian folder, it is in ApplicationData\Bitbucket\shared\data\repositories\[repository#]\hooks\.
Bitbucket keeps track of repos internally using numbers and not names so in the above replace [repository#] with the repo number. That can be found out this way.
Put the pre-receive hook in the pre-receive.d folder. Put the post-receive hook in the post-receive.d folder.
The names of the hooks/files should begin with a number. That determines what order the hooks are 'activated'. Begin the numbers with at least 21 because the default hook in the folder begins with 20. You want your hook to be activated after the one shipped with Bitbucket server. So a file name for a pre-receive hook could be 21_pre_receive.
Don't change the default hooks that are in the folder because they are needed to help Bitbucket work.

d13655 | train | The snapshot too old error is more or less directly related to the running time of your queries (often a cursor of a FOR loop). So the best solution is to optimize your queries so they run faster.
As a short term solution you can try to increase the size of the UNDO log.
Update:
The UNDO log stores the previous version of a record before it's updated. It is used to rollback transactions and to retrieve older version of a record for consistent data snapshots for long running queries.
You'll probably need to dive into Oracle DB administration if you want to solve it via increasing the UNDO log. Basically you do (as SYSDBA):
ALTER SYSTEM SET UNDO_RETENTION = 21600;
21600 is 6 hours in seconds.
However, Oracle will only keep 6 hours of old data if the UNDO log files are big enough, which depends on the size of the rollback segments and the amount of updates executed on the database.
So in addition to changing the undo retention time, you should also make sure that few concurrent updates are executed while your job is running. In particular, updates of the data your job is reading should be minimized.
If everything fails, increase the UNDO logs.
A: The best explanation of the ORA-01555 snapshot too old error that I've read, is found in this AskTom thread

*call servlet.service(request, response).

d13658 | train | You can set $.ajax 's traditional attribute and set it to true, to send json data as url encoded form. Make sure to set type:'POST'. With this method you can even send arrays and you do not have to use JSON.stringyfy or any changes on server side (e.g. creating custom attributes to sniff header )
I have tried this on ASP.NET MVC3 and jquery 1.7 setup and it's working
following is the code snippet.
var data = { items: [1, 2, 3], someflag: true};
data.__RequestVerificationToken = $(':input[name="__RequestVerificationToken"]').val();
$.ajax({
url: 'Test/FakeAction'
type: 'POST',
data: data
dataType: 'json',
traditional: true,
success: function (data, status, jqxhr) {
// some code after succes
},
error: function () {
// alert the error
}
});
This will match with MVC action with following signature
[HttpPost]
[Authorize]
[ValidateAntiForgeryToken]
public ActionResult FakeAction(int[] items, bool someflag)
{
}
A: You don't need the ValidationHttpRequestWrapper solution since MVC 4. According to this link.
*
*Put the token in the headers.
*Create a filter.
*Put the attribute on your method.
Here is my solution:
var token = $('input[name="__RequestVerificationToken"]').val();
var headers = {};
headers['__RequestVerificationToken'] = token;
$.ajax({
type: 'POST',
url: '/MyTestMethod',
contentType: 'application/json; charset=utf-8',
headers: headers,
data: JSON.stringify({
Test: 'test'
}),
dataType: "json",
success: function () {},
error: function (xhr) {}
});
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, AllowMultiple = false, Inherited = true)]
public class ValidateJsonAntiForgeryTokenAttribute : FilterAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationContext filterContext)
{
if (filterContext == null)
{
throw new ArgumentNullException("filterContext");
}
var httpContext = filterContext.HttpContext;
var cookie = httpContext.Request.Cookies[AntiForgeryConfig.CookieName];
AntiForgery.Validate(cookie != null ? cookie.Value : null, httpContext.Request.Headers["__RequestVerificationToken"]);
}
}
[HttpPost]
[AllowAnonymous]
[ValidateJsonAntiForgeryToken]
public async Task<JsonResult> MyTestMethod(string Test)
{
return Json(true);
}
A: What is wrong is that the controller action that is supposed to handle this request and which is marked with the [ValidateAntiForgeryToken] expects a parameter called __RequestVerificationToken to be POSTed along with the request.
There's no such parameter POSTed as you are using JSON.stringify(data) which converts your form to its JSON representation and so the exception is thrown.
So I can see two possible solutions here:
Number 1: Use x-www-form-urlencoded instead of JSON for sending your request parameters:
data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val();
data["fiscalyear"] = fiscalyear;
// ... other data if necessary
$.ajax({
url: url,
type: 'POST',
context: document.body,
data: data,
success: function() { refresh(); }
});
Number 2: Separate the request into two parameters:
data["fiscalyear"] = fiscalyear;
// ... other data if necessary
var token = $('[name=__RequestVerificationToken]').val();
$.ajax({
url: url,
type: 'POST',
context: document.body,
data: { __RequestVerificationToken: token, jsonRequest: JSON.stringify(data) },
success: function() { refresh(); }
});
So in all cases you need to POST the __RequestVerificationToken value.
A: You can't validate an content of type contentType: 'application/json; charset=utf-8' because your date will be uploaded not in the Form property of the request, but in the InputStream property, and you will never have this Request.Form["__RequestVerificationToken"].
This will be always empty and validation will fail.
A: You won't ever have to validate an AntiForgeryToken when you receive posted JSON.
The reason is that AntiForgeryToken has been created to prevent CSRF. Since you can't post AJAX data to another host and HTML forms can't submit JSON as the request body, you don't have to protect your app against posted JSON.
A: I have resolved it globally with RequestHeader.
$.ajaxPrefilter(function (options, originalOptions, jqXhr) {
if (options.type.toUpperCase() === "POST") {
// We need to add the verificationToken to all POSTs
if (requestVerificationTokenVariable.length > 0)
jqXhr.setRequestHeader("__RequestVerificationToken", requestVerificationTokenVariable);
}
});
where the requestVerificationTokenVariable is an variable string that contains the token value.
Then all ajax call send the token to the server, but the default ValidateAntiForgeryTokenAttribute get the Request.Form value.
I have writed and added this globalFilter that copy token from header to request.form, than i can use the default ValidateAntiForgeryTokenAttribute:
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new GlobalAntiForgeryTokenAttribute(false));
}
public class GlobalAntiForgeryTokenAttribute : FilterAttribute, IAuthorizationFilter
{
private readonly bool autoValidateAllPost;
public GlobalAntiForgeryTokenAttribute(bool autoValidateAllPost)
{
this.autoValidateAllPost = autoValidateAllPost;
}
private const string RequestVerificationTokenKey = "__RequestVerificationToken";
public void OnAuthorization(AuthorizationContext filterContext)
{
var req = filterContext.HttpContext.Request;
if (req.HttpMethod.ToUpperInvariant() == "POST")
{
//gestione per ValidateAntiForgeryToken che gestisce solo il recupero da Request.Form (non disponibile per le chiamate ajax json)
if (req.Form[RequestVerificationTokenKey] == null && req.IsAjaxRequest())
{
var token = req.Headers[RequestVerificationTokenKey];
if (!string.IsNullOrEmpty(token))
{
req.Form.SetReadOnly(false);
req.Form[RequestVerificationTokenKey] = token;
req.Form.SetReadOnly(true);
}
}
if (autoValidateAllPost)
AntiForgery.Validate();
}
}
}
public static class NameValueCollectionExtensions
{
private static readonly PropertyInfo NameObjectCollectionBaseIsReadOnly = typeof(NameObjectCollectionBase).GetProperty("IsReadOnly", BindingFlags.FlattenHierarchy | BindingFlags.NonPublic | BindingFlags.Instance);
public static void SetReadOnly(this NameValueCollection source, bool readOnly)
{
NameObjectCollectionBaseIsReadOnly.SetValue(source, readOnly);
}
}
This work for me :)
A: I hold the token in my JSON object and I ended up modifying the ValidateAntiForgeryToken class to check the InputStream of the Request object when the post is json. I've written a blog post about it, hopefully you might find it useful.
A: Check out Dixin's Blog for a great post on doing exactly that.
Also, why not use $.post instead of $.ajax?
Along with the jQuery plugin on that page, you can then do something as simple as:
data = $.appendAntiForgeryToken(data,null);
$.post(url, data, function() { refresh(); }, "json");
A: AJAX based model posting with AntiForgerytoken can be made bit easier with Newtonsoft.JSON library
Below approach worked for me:
Keep your AJAX post like this:
$.ajax({
dataType: 'JSON',
url: url,
type: 'POST',
context: document.body,
data: {
'__RequestVerificationToken': token,
'model_json': JSON.stringify(data)
};,
success: function() {
refresh();
}
});
Then in your MVC action:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(FormCollection data) {
var model = JsonConvert.DeserializeObject < Order > (data["model_json"]);
return Json(1);
}
Hope this helps :)
A: I was just implementing this actual problem in my current project. I did it for all Ajax POSTs that needed an authenticated user.
First off, I decided to hook my jQuery Ajax calls so I do not to repeat myself too often. This JavaScript snippet ensures all ajax (post) calls will add my request validation token to the request. Note: the name __RequestVerificationToken is used by the .NET framework so I can use the standard Anti-CSRF features as shown below.
$(document).ready(function () {
securityToken = $('[name=__RequestVerificationToken]').val();
$('body').bind('ajaxSend', function (elm, xhr, s) {
if (s.type == 'POST' && typeof securityToken != 'undefined') {
if (s.data.length > 0) {
s.data += "&__RequestVerificationToken=" + encodeURIComponent(securityToken);
}
else {
s.data = "__RequestVerificationToken=" + encodeURIComponent(securityToken);
}
}
});
});
In your Views where you need the token to be available to the above JavaScript code, just use the common HTML-Helper. You can basically add this code wherever you want. I placed it within a if(Request.IsAuthenticated) statement:
@Html.AntiForgeryToken() // You can provide a string as salt when needed which needs to match the one on the controller
In your controller simply use the standard ASP.NET MVC anti-CSRF mechanism. I did it like this (though I actually used a salt).
[HttpPost]
[Authorize]
[ValidateAntiForgeryToken]
public JsonResult SomeMethod(string param)
{
// Do something
return Json(true);
}
With Firebug or a similar tool you can easily see how your POST requests now have a __RequestVerificationToken parameter appended.
A: I had to be a little shady to validate anti-forgery tokens when posting JSON, but it worked.
//If it's not a GET, and the data they're sending is a string (since we already had a separate solution in place for form-encoded data), then add the verification token to the URL, if it's not already there.
$.ajaxSetup({
beforeSend: function (xhr, options) {
if (options.type && options.type.toLowerCase() !== 'get' && typeof (options.data) === 'string' && options.url.indexOf("?__RequestVerificationToken=") < 0 && options.url.indexOf("&__RequestVerificationToken=") < 0) {
if (options.url.indexOf('?') < 0) {
options.url += '?';
}
else {
options.url += '&';
}
options.url += "__RequestVerificationToken=" + encodeURIComponent($('input[name=__RequestVerificationToken]').val());
}
}
});
But, as a few people already mentioned, the validation only checks the form - not JSON, and not the query string. So, we overrode the attribute's behavior. Re-implementing all of the validation would have been terrible (and probably not secure), so I just overrode the Form property to, if the token were passed in the QueryString, have the built-in validation THINK it was in the Form.
That's a little tricky because the form is read-only, but doable.
if (IsAuth(HttpContext.Current) && !IsGet(HttpContext.Current))
{
//if the token is in the params but not the form, we sneak in our own HttpContext/HttpRequest
if (HttpContext.Current.Request.Params != null && HttpContext.Current.Request.Form != null
&& HttpContext.Current.Request.Params["__RequestVerificationToken"] != null && HttpContext.Current.Request.Form["__RequestVerificationToken"] == null)
{
AntiForgery.Validate(new ValidationHttpContextWrapper(HttpContext.Current), null);
}
else
{
AntiForgery.Validate(new HttpContextWrapper(HttpContext.Current), null);
}
}
//don't validate un-authenticated requests; anyone could do it, anyway
private static bool IsAuth(HttpContext context)
{
return context.User != null && context.User.Identity != null && !string.IsNullOrEmpty(context.User.Identity.Name);
}
//only validate posts because that's what CSRF is for
private static bool IsGet(HttpContext context)
{
return context.Request.HttpMethod.ToUpper() == "GET";
}
...
internal class ValidationHttpContextWrapper : HttpContextBase
{
private HttpContext _context;
private ValidationHttpRequestWrapper _request;
public ValidationHttpContextWrapper(HttpContext context)
: base()
{
_context = context;
_request = new ValidationHttpRequestWrapper(context.Request);
}
public override HttpRequestBase Request { get { return _request; } }
public override IPrincipal User
{
get { return _context.User; }
set { _context.User = value; }
}
}
internal class ValidationHttpRequestWrapper : HttpRequestBase
{
private HttpRequest _request;
private System.Collections.Specialized.NameValueCollection _form;
public ValidationHttpRequestWrapper(HttpRequest request)
: base()
{
_request = request;
_form = new System.Collections.Specialized.NameValueCollection(request.Form);
_form.Add("__RequestVerificationToken", request.Params["__RequestVerificationToken"]);
}
public override System.Collections.Specialized.NameValueCollection Form { get { return _form; } }
public override string ApplicationPath { get { return _request.ApplicationPath; } }
public override HttpCookieCollection Cookies { get { return _request.Cookies; } }
}
There's some other stuff that's different about our solution (specifically, we're using an HttpModule so we don't have to add the attribute to every single POST) that I left out in favor of brevity. I can add it if necessary.
A: Unfortunately for me, the other answers rely on some request formatting handled by jquery, and none of them worked when setting the payload directly. (To be fair, putting it in the header would have worked, but I did not want to go that route.)
To accomplish this in the beforeSend function, the following works. $.params() transforms the object into the standard form / url-encoded format.
I had tried all sorts of variations of stringifying json with the token and none of them worked.
$.ajax({
...other params...,
beforeSend: function(jqXHR, settings){
var token = ''; //get token
data = {
'__RequestVerificationToken' : token,
'otherData': 'value'
};
settings.data = $.param(data);
}
});
```
A: You should place AntiForgeryToken in a form tag:
@using (Html.BeginForm(actionName:"", controllerName:"",routeValues:null, method: FormMethod.Get, htmlAttributes: new { @class="form-validator" }))
{
@Html.AntiForgeryToken();
}
Then in javascript modify the following code to be
var DataToSend = [];
DataToSend.push(JSON.stringify(data), $('form.form-validator').serialize());
$.ajax({
dataType: 'JSON',
contentType: 'application/json; charset=utf-8',
url: url,
type: 'POST',
context: document.body,
data: DataToSend,
success: function() {
refresh();
}
});
Then you should be able to validate the request using ActionResult annotations
[ValidateAntiForgeryToken]
[HttpPost]

d13659 | train | Not sure about JetS3t API but, the AWS SDK for Java does provide a simple copyObject method
A: so i ended up figuring out how to do clone the asset in s3 using JetS3t. it was simpler than i expected. i'll post it up incase anyone ever googles this question.
all do is first get the s3 object you want to clone. after you have it, call setKey(filename) on the s3 object. "filename" is the path for where you want the object to be followed by the file name itself i.e. yours3bucketname/products/assets/picture.png

d13660 | train | The "fetchval" method in your parent is not referencing your child but the "value" property in your data function. "this" refers to your parent component. Basically, you are trying to call a "getVal" function on a string in your parent.
If you want to call a function on your child component, you need a reference to the child and call that function on that reference. You need to add a ref to your child component. If you're not familiar with refs, I suggest starting here: Template Refs | unknown | |

d13663 | train | You can get an object describing the current tab the user is looking at using browser.tabs.getCurrent(). This object has a property url, which you can then use to make an XMLHttpRequest.
browser.tabs.getCurrent().then(currentTab => {
let xhr = new XMLHttpRequest();
xhr.open("GET", currentTab.url);
// ...
});
Edit:
As pointed out by Makyen, tabs.currentTab is not actually what you want. Instead tabs.query with active: true should be used. Something like that should work:
browser.tabs.query({active: true, currentWindow: true}).then(tabs => {
let currentTab = tabs[0];
let xhr = new XMLHttpRequest();
xhr.open("GET", currentTab.url);
// ...
})
In order to make cross origin requests, you will need to get permission in your manifest.json file:
{

"permissions": [
"tabs",
"<all_urls>"

<all_urls>for instance will allow you to make http requests to any url.

because I like the cycle method.
A: a.each_slice(group_size).to_a.transpose
Will work given that your data is accurately portrayed in the example. If it is not please supply accurate data so that we can answer the question more appropriately.
e.g.
a= [
{ name: "foo1", location: "new york" },
{ name: "foo2", location: "new york" },
{ name: "foo3", location: "new york" },
{ name: "bar1", location: "new york" },
{ name: "bar2", location: "new york" },
{ name: "bar3", location: "new york" },
{ name: "baz1", location: "chicago" },
{ name: "baz2", location: "chicago" },
{ name: "baz3", location: "chicago" },
{ name: "quux1", location: "chicago" },
{ name: "quux2", location: "chicago" },
{ name: "quux3", location: "chicago" }
]
group_size = 3
a.each_slice(group_size).to_a.transpose
#=> [
[
{:name=>"foo1", :location=>"new york"},
{:name=>"bar1", :location=>"new york"},
{:name=>"baz1", :location=>"chicago"},
{:name=>"quux1", :location=>"chicago"}
],
[
{:name=>"foo2", :location=>"new york"},
{:name=>"bar2", :location=>"new york"},
{:name=>"baz2", :location=>"chicago"},
{:name=>"quux2", :location=>"chicago"}
],
[
{:name=>"foo3", :location=>"new york"},
{:name=>"bar3", :location=>"new york"},
{:name=>"baz3", :location=>"chicago"},
{:name=>"quux3", :location=>"chicago"}
]
]
each_slice 3 will turn this into 4 equal groups (numbered 1,2,3) in your example. transpose will then turn these 4 groups into 3 groups of 4.
If the locations are not necessarily in order you can add sorting to the front of the method chain
a.sort_by { |h| h[:location] }.each_slice(group_size).to_a.transpose
Update
It was pointed out that an uneven number of arguments for transpose will raise. My first though was to go with @CarySwoveland's approach but since he already posted it I came up with something a little different
class Array
def indifferent_transpose
arr = self.map(&:dup)
max = arr.map(&:size).max
arr.each {|a| a.push(*([nil] * (max - a.size)))}
arr.transpose.map(&:compact)
end
end
then you can still use the same methodology
a << {name: "foobar1", location: "taiwan" }
a.each_slice(group_size).to_a.indifferent_transpose
#=> [[{:name=>"foo1", :location=>"new york"},
{:name=>"bar1", :location=>"new york"},
{:name=>"baz1", :location=>"chicago"},
{:name=>"quux1", :location=>"chicago"},
#note the extras values will be placed in the group arrays in order
{:name=>"foobar4", :location=>"taiwan"}],
[{:name=>"foo2", :location=>"new york"},
{:name=>"bar2", :location=>"new york"},
{:name=>"baz2", :location=>"chicago"},
{:name=>"quux2", :location=>"chicago"}],
[{:name=>"foo3", :location=>"new york"},
{:name=>"bar3", :location=>"new york"},
{:name=>"baz3", :location=>"chicago"},
{:name=>"quux3", :location=>"chicago"}]]
A: Here's another way to do it.
Code
def group_em(a, ngroups)
a.each_with_index.with_object(Array.new(ngroups) {[]}) {|(e,i),arr|
arr[i%ngroups] << e}
end
Example
a = [
{ name: "foo1", location: "new york" },
{ name: "foo2", location: "new york" },
{ name: "foo3", location: "new york" },
{ name: "bar1", location: "new york" },
{ name: "bar2", location: "new york" },
{ name: "bar3", location: "new york" },
{ name: "baz1", location: "chicago" },
{ name: "baz2", location: "chicago" },
{ name: "baz3", location: "chicago" },
{ name: "quux1", location: "chicago" },
{ name: "quux2", location: "chicago" }
]
Note that I've omitted the last element of a from the question in order for a to have an odd number of elements.
group_em(a,3)
#=> [[{:name=>"foo1", :location=>"new york"},
# {:name=>"bar1", :location=>"new york"},

A: Just use:
aBank.getAccounts().get(i).getTransaction().get(j).getTransDate().get(Calendar.MONTH) == month
A: If all of the XYZ.getTransDate() returns Calendar, then
XYZ.getTransDate().get(SOMETHING) returns primitive int. Primitives do not have comapreTo method, just use ==
so instead of XYZ.getTransDate().get(MONTH).compareTo(month) == 0 use
XYZ.getTransDate().get(MONTH) == month

d13670 | train | As far as I know, the shortest way is:
var myStruct = TheStruct()

func foo(arg:UnsafeMutablePointer<Void>) {

d13671 | train | The behavior you observed :
The real confusing part is that it doesn't reinitialize it to 0 every time the recursive function calls itself. It's like this whole line of code static int i = 0; is skipped?
is exactly what you are asking for with static. A local static variable is initalized the first time its definition (i.e, the line static int i = 0;) is reached.
In your case it means it will be set to zero only on the first call ever to this method during the whole runtime of your program. There is no notion of multiple recursive calls to the same function, so it will make no difference if the method is invoked by itself (the multiple recursive call you are referring to) or if you are starting a whole new stack of recursion somewhere else in your client code.
Possible solution
To go back on your description, it will only work with i being static (for n!=1) because, if your removed static keyword, then i would be initialized to zero each time the method is entered (a different local instance of i for each invocation of the method). Thus in your condition
if(++i == n)
++i would always evaluate to 1, independently of the recursion depth.
If you want the static i to be reinitialized each time you call your method in your client code (i.e. to start a new stack of recursion), you could write it like :
void printNthFromLast(Node* head, int n, bool reinit=true)
{
static int i = 0;
if(reinit)
{
i=0;
}
if(head == nullptr)
return;
printNthFromLast(head->next, n, false);
if(++i == n)
cout << head->data;
}
Thread safe with tail call optimization
A cleaner solution would be to have i as a mutable parameter to the function, so your function would be thread-safe. And with a better ordering of the operation, you do not need to save the previous invocation frame, thus enjoying tail call optimization offered by most of recent compilers.
EDIT : As pointed by Matthieu, my original implementation printed the Nth element instead of the Nth from last element. Fixing while enabling TCO is less elegant, but can be done as follows :
/// n==1 means printing the last element here
static void printNthFromLastImpl(const Node* currentNode, const Node* offsetNode, const int n, int currentDepth)
{
// n == 0 will never print in the original example by op, so forbid it
assert(n);
if(++currentDepth > n)
{
offsetNode = offsetNode->next;
}
if(currentNode->next)
{
currentNode = currentNode->next;
}
else
{
if(currentDepth >= n)
{
cout << offsetNode->data;
}
return;
}
return printNthFromLastImpl(currentNode, offsetNode, n, currentDepth);
}
/// \brief : code to call from client
static void printNthFromLast(const Node* head, const int n)
{
if (head)
{
printNthFromLastImpl(head, head, n, 0);
}
}
A: When you declare a static local variable the compiler only initializes it once (the first time control flow passes over the variable declaration); thereafter the variable keeps its value across all calls to the function that declares it for the lifetime of the program, much like a global variable.
How is this achieved?
When the compiler sees something like this:
void foo() {
static int i = 0;
cout << i++;
}
It produces code equivalent to this:
bool foo_i_initialized = false; // global
int foo_i; // global
void foo() {
if (!foo_i_initialized) {
foo_i = 0;
foo_i_initialized = true;
}
cout << foo_i++;
}
The above example is a bit contrived because here foo_i is a primitive initialized with a constant and as such it could have been statically initialized in global scope (removing the need for the boolean flag), but this mechanism also handles more complicated scenarios.
A: The initialization is only executed at the first call of the function. Subsequent calls will use the already inititalized value.
A: So, as said, static int i = 0; is local to the function. It is initialized the first time flow-control passes through its definition, and skipped ever after. Two special cases are made:
*
*in case of dynamic initialization (by a function) which throws an exception, initialization will be reattempted the next time flow-control passes through the definition.
*in case of calls from multiple threads, the first thread does the initialization and all others are blocked until it is done (or fails with an exception)
Now, regarding your code: don't. A local static is a global variable in disguise, your code is equivalent to:
int i = 0;
void printNthFromLast(Node* head, int n) {
if(head == nullptr)
return;
printNthFromLast(head->next, n);
if(++i == n)
cout << head->data;
}
Note: not only is it more difficult to debug, it is also not thread-safe.
Instead, you should provide a local variable for this usage:
static void printNthFromLastImpl(Node const* const head, int& i, int const n) {
if(head == nullptr)
return;
printNthFromLastImpl(head->next, i, n);
if(++i == n)
cout << head->data;
}
// Each call to this function instantiates a new `i` object.
void printNthFromLast(Node const* const head, int const n) {
int i = 0;
printNthFromLastImpl(head, i, n);
}
EDIT: As remarked by Ad N, since the list is not modified it should be passed by const pointer.
Following Ad N latest edit (TCO version), I realized an iterative implementation should work (note, there might be some off by one errors).
void printNthFromLast(Node const* const head, int const n) {
if (n == 0) { return; }
// Set "probe" to point to the nth item.
Node const* probe = head;
for (int i = 0; i != n; ++i) {
if (probe == nullptr) { return; }
probe = probe->next;
}
Node const* current = head;
// Move current and probe at the same rhythm;
// when probe reaches the end, current is the nth from the end.
while (probe) {
current = current->next;
probe = probe->next;
}
std::cout << current->data;
}
A: You've described it very well yourself. A static variable is initialised only once, the first time through the function, and the variable is then shared across calls to the function.
A: A variable declared static is initialized only once. So even, when the function is called again, the value of the variable i here in this context is retained from the previous call.
The next time the program reaches the static initialize statement to an initialized variable, it skips the statement.
Since, static variables are stored in the BSS segment and not on the stack, the previous state of the variable in previous function calls, is not altered.
A: Not only shared among multiple recursive calls, shared among all calls.
There is actually only a single instance of the variable i, and it's shared among all calls of the function. | unknown | |

d13676 | train | If you write inter1 obj = ... then you will not be able to write obj.method2) unless you cast to inter2 or to a type that implements inter2.
For example
inter1 obj = quest();
if (obj instanceof class1)
((class1) obj).method2();
or
inter1 obj = quest();
if (obj instanceof inter2)
((inter2) obj).method2();
As an aside, when you write in Java you normally give classes and interfaces names that begin the a capital letter, otherwise you confuse people reading your code.
A: Using genecics it is possible to declare generic reference implementing more than one type. You can invoke method from each interface it implements without casting. Example below:
public class TestTwoTypes{
public static void main(String[] args) {
testTwoTypes();
}
static <T extends Type1 & Type2> void testTwoTypes(){
T twoTypes = createTwoTypesImplementation();
twoTypes.method1();
twoTypes.method2();
}
static <T extends Type1 & Type2> T createTwoTypesImplementation(){
return (T) new Type1AndType2Implementation();
}
}
interface Type1{
void method1();
}
interface Type2{
void method2();
}
class Type1AndType2Implementation implements Type1, Type2{
@Override
public void method1() {
System.out.println("method1");
}
@Override
public void method2() {
System.out.println("method2");
}
}
The output is:
method1
method2

Description = new Description
{
English = "englishFoo5",
French = "frenchFoo5"
}
}
});
foos.Add(new Foo {
Name = "Foo6",
Lookup = new Lookup
{
Name = "Lookup6"
}
});
return View(foos);
}
So, I now have Foos with or without Lookups (with or without Description).
The view is as follows:
@model IEnumerable<Foo>
@{
var grid = new WebGrid(Model, defaultSort: "sortMe", rowsPerPage: 10);
grid.GetHtml(htmlAttributes: new { id = "DataTable" });
}
@grid.GetHtml(
columns: grid.Columns(
grid.Column(
columnName: "Name",
header: "Foo"
),
grid.Column(
columnName: "Lookup.Name",
header: "Lookup",
format: @<span>@if (item.Lookup != null)
{ @item.Lookup.Name }
</span>
),
grid.Column(
columnName: "Lookup.Description.English",
header: "Description.English",
format: @<span>@if (item.Lookup != null && item.Lookup.Description != null)
{ @item.Lookup.Description.English }
</span>
),
grid.Column(
columnName: "Lookup.Description.French",
header: "Description.French",
format: @<span>@if (item.Lookup != null && item.Lookup.Description != null)
{ @item.Lookup.Description.French }
</span>
)
)
)
which works just fine for me (Asp.Net MVC 3), it procudes the following html:
[snip]
<tr>
<td>Foo4</td>
<td><span></span></td>
<td><span></span></td>
<td><span></span></td>
</tr>
<tr>
<td>Foo5</td>
<td><span></span></td>
<td><span>englishFoo5 </span></td>
<td><span>frenchFoo5 </span></td>
</tr>
<tr>
<td>Foo6</td>
<td><span>Lookup6</span></td>
<td><span></span></td>
<td><span></span></td>
</tr>

*
*sklearn.preprocessing.MultiLabelBinarizer to transform each basket into a 0-1 vector with one coordinate per food type;
*sklearn.cluster.AgglomerativeClustering to make clusters, with baskets in the same cluster if they differ by at most 8 food types (8 = 2 * 4 = 2 * (10 - 6), so if two baskets have exactly 6 food types in common, then their vectors will differ by 8 coordinates)
*AgglomerativeClustering().fit_predict() returns a list of numbers: number x at index i in the list means that the ith basket is in the xth cluster.
*itertools.groupby with zip can be used to get the clusters as a list of lists of baskets.

A: $pdo = new PDO(
'mysql:host=hostname;dbname=database;charset=utf-8',
'username',
'password'
);
$pdo->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );
$stmt = $pdo->query('SELECT ID, Category, Summary, Text FROM Table');
if ( $stmt !== false )
{
$data = $stmt->fetchAll( PDO::FETCH_ASSOC );
}
In the case if the SQL query has no conditions, use query() , otherwise, you should be using prepare() ans bind the parameters.
Oh .. and please stop using the ancient mysql_* functions, they are in the process of being deprecated and no new code should written with them. | unknown | |
d13690 | train | After creating your JComboBox with your empty Vector, you set the selectedIndex to loginy.capacity (). The problem is that while the capacity of your Vector is 10 (as stated in the JavaDoc for the default constructor), it's actual size is 0. Hence the ArrayOutOfBoundsException. You should check for the size of your Vector before setting the selected index of your JComboBox.
A: I suspect the problem is you are trying to set the selected index of your combo box to the capacity of your vector.
loginList.setSelectedIndex(loginy.capacity());
From the docs .capacity():
Returns the current capacity of this vector.
Returns:
the current capacity (the length of its internal data array, kept in the field elementData of this vector)
This is not the size i.e. the number of logins in your database. this is the capacity of internal datastructure which will always be >= the number of elements in the vector.
Try using Vector#size() but you will still need to subtract one (provided there is actually data in the vector) from this so your code should be:
loginList.setSelectedIndex(loginy.size() - 1);
And this will set the last login in the comboBox. Which is not required in your case as you are populating the vector after creating the combobox so you could just remove this line from your code until you populate the vector.
Edit as per comments
All you should need to do to have the logins is reorder the execution order. I.e populate your vector then create your combo box, Change your main method to something like this:
public static void main(String[] args) {
//First initialise your database (dont do this in the action performed method)
// you should only need one and not need to create a new one on each action
DATABASE = new DatabaseManagement("pacjent");
// Read logins (I assume this is the method that does it)
DATABASE.loginReader(loginy,"uzytkownicy");
// Then create your message window...
Message window = new Message();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setVisible(true);

d13692 | train | You can make a context which enables easy access to the alert anywhere in the application.
AlertProvider.js
import React, { useState, useCallback, useContext, createContext } from 'react'
const AlertContext = createContext()
export function AlertProvider(props) {
const [open, setOpen] = useState(false)
const [message, setMessage] = useState()
const handleClose = useCallback(() => {
setOpen(false)
}, [setOpen])
const handleOpen = useCallback(message => {
setMessage(message)
setOpen(true)
}, [setMessage, setOpen])
return (
<AlertContext.Provider value={[handleOpen, handleClose]}>
{props.children}
<Alert color="info" isOpen={open} toggle={handleClose} >
{message}
</Alert>
</AlertContext.Provider>
)
}
export function useAlert() {
const context = useContext(AlertContext);
if (!context)
throw new Error('`useAlert()` must be called inside an `AlertProvider` child.')
return context
}
Update your App.js
import { Alert } from 'reactstrap';
import { AlertProvider } from './AlertProvider';
function App() {
return (
<AlertProvider>
<Router>
<div className="App">
<nav className="navbar navbar-expand-lg navbar-light fixed-top">
<div className="container">
<Link className="navbar-brand" to={"/add"}>
Chicommons
</Link>
<NavBar />
</div>
</nav>
<div className="auth-wrapper">
<div className="auth-inner">
<Switch>
<Route exact path="/" component={Add} />
<Route path="/add" component={Add} />
<Route path="/edit/:id" component={Edit} />
<Route path="/search" component={Search} />
<Route path="/:coop_id/people" component={AddPerson} />
<Route path="/:coop_id/listpeople" component={ListPeople} />
</Switch>
</div>
</div>
</div>
</Router>
</AlertProvider>
);
}
export default App;
You can then use this in functional components:
import React, { useEffect } from 'react'
import { useAlert } from './AlertProvider'
function MyComponent() {
const [open, close] = useAlert();
useEffect(() => {
// when some condition is met
open("Hi") // closable with the toggle, or in code via close()
})
}
This uses an imperative mood to open and close by calling open() and close(). If you want a declarative mood, the context should instead directly return the setMessage and setOpen functions.
You can also play around to place the alert component in some other place.
A: Just below function App() {. add:
const [alertMessage, setAlertMessage] = React.useState("")
And change your alert to:
<Alert color="info" isOpen={alertMessage!=""} toggle={()=>setAlertMessage("")} >
{alertMessage}
</Alert>
And then I don't know how the rest of your app is laid out, but you want to pass in the setAlertMessage function into handleFormSubmit as a callback, and call it in/near setErrors | unknown | |

d13694 | train | When the form is submitted to the server the page is reloaded. Unless you set the submitted values in the textboxes upon loading the page again they are cleared. ASP.NET MVC doesn't use Viewstate like ASP.NET WebForms so unless you manually init the fields they will be empty when pages are reloaded after a form submission.
Update:
You can also submit the form data via jQuery. In order to do that you would do something like this:
*
*Add a click handler to the submit button. (If it is declared as you should also change it to a normal button so that the browser wont submit the form automatically.
*In the click handler add code to do the ajax submission. See this question for tips on that Submit form using AJAX and jQuery
But en the end it might be easier to just put the submitted data in the viewmodel and reinitialize the fields in the view after submission. | unknown | |
d13695 | train | You are not in any event handling or callback context here, so $(this) simply refers to the window object (wrapped in jQuery.)
Go through the li in a loop, then $(this) will have the proper context inside the callback function.
$("li").each(function() {
$(this).text("this ol's index is " + $(this).closest("ol").index());
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

d13696 | train | Yes, of course. In fact you can find a lot of examples:
There are some ready implementations like tf.contrib.learn.LinearClassifier in https://www.tensorflow.org/tutorials/wide

d13697 | train | Draw a block of the desired undercolor on the image, then annotate the image such that the text is over the block.
To determine the desired size of the block, use get_type_metrics or get_multiline_type_metrics to get the dimensions of your text, then add in how much padding you want.
A: Annotate in ImageMagick does not have any option to pad the undercolor. But you can trick it. The simplest ways is to put spaces on the left and right side of your text using "\ ". But that will only pad on the left and right. In label: you can add newlines, but that does not work in annotate. You could add -interline-spacing, but that will only pad on the bottom. But here is a trick. Create text in the undercolor with a slightly larger pointsize, then write over it with your desired color text. For example:
Without padding:
convert logo.jpg -gravity center -undercolor pink -pointsize 24 -fill black -annotate +0+0 "This Is Some Text" result1.jpg
With padding:
convert logo.jpg -gravity center -pointsize 34 -undercolor pink -fill pink -annotate +0+0 "X X" -pointsize 24 -fill black -annotate +0+0 "This Is Some Text" result2.jpg
Alternately, you could just draw a pink rectangle in the center of the image of the desired size. | unknown | |
d13698 | train | Based on how my app was set up I ultimately decided to remove the photoURL property altogether since it could be defined elsewhere in the app. After testing, only one of my images worked. This is why I experienced the full profile updates working out sometimes since random images were selected each time a new user signs up. I ended up sticking wth this image as the default image.
As @adsy mentioned, my profile updates weren't happening consistently because certain profile images I had exceeded the allowed input body length for this property. The example in the Docs shows a link with 43 characters but no other information. The path to the profile images in the question are much shorter than this so I still need some understanding.
After researching a bit, I didn't come across the maximum limit set. It's now something to contact Google Developer's support team about. If anyone has the information for the allowed input body length for this property, feel free to share it on this post.
Thanks!

String sql = "insert into abcnews_topics VALUES (null, ?)";
try (PreparedStatement statement = connection.prepareStatement(sql)) {
statement.setString(1, textTopic);
statement.execute();
}
(The try-with-resources statement will close the PreparedStatement automatically. If you're using Java 6 or earlier, use a try/finally block to do it yourself.)
Note that I've changed the text_topic variable to textTopic to follow Java naming conventions, renamed stmt to statement to avoid abbreviation, and also moved the declaration of statement to the assignment. (There's no point in declaring it earlier: try to limit scope where possible.) | unknown |
