Really it comes down to what you want the query to do. If you mean an exact match then use =. If you mean a fuzzier match, then use LIKE. Saying what you mean is usually a good policy with code.

1. As per https://msdn.microsoft.com/en-us/library/ms180065.aspx, "DBCC USEROPTIONS reports an isolation level of 'read committed snapshot' when the database option READ_COMMITTED_SNAPSHOT is set to ON and the transaction isolation level is set to 'read committed'. The actual isolation level is read committed."

2. Also in SQL Server Management Studio, in database properties under Options->Miscellaneous there is "Is Read Committed Snapshot On" option status

In Oracle, something like this works nicely to separate your counting and ordering a little better. I'm not sure if it will work in MySql 4.

select 'Tag', counts.cnt
from
  (
  select count(*) as cnt, 'Tag'
  from 'images-tags'
  group by 'tag'
  ) counts
order by counts.cnt desc

You want conda update --all.

conda search --outdated will show outdated packages, and conda update --all will update them (note that the latter will not update you from Python 2 to Python 3, but the former will show Python as being outdated if you do use Python 2).

You are not returning. Change to

this.state.data.map(function(item, i){
  console.log('test');
  return <li>Test</li>;
})

check this code:

CREATE TRIGGER trig_Update_Employee ON [EmployeeResult] FOR INSERT AS Begin   
    Insert into Employee (Name, Department)  
    Select Distinct i.Name, i.Department   
        from Inserted i
        Left Join Employee e on i.Name = e.Name and i.Department = e.Department
        where e.Name is null
End

A delayed response but to give multiple packages using annotation based approach we can use as below:

@ComponentScan({"com.my.package.one","com.my.package.subpackage.two","com.your.package.supersubpackage.two"})

Simply use the css entry of min-height to one of the cells of your table row. Works on old browsers too.

.rowNumberColumn {
    background-color: #e6e6e6;
    min-height: 22;
}

<table width="100%" cellspacing="0" class="htmlgrid-table">
    <tr id="tr_0">
            <td width="3%" align="center" class="readOnlyCell rowNumberColumn">1</td>
            <td align="left" width="40%" id="td_0_0" class="readOnlyCell gContentSection">411978430-Intimate:Ruby:Small</td>

You can find many whitepapers on the net dealing with this subject.

"BypassTraverseChecking" means that you can directly access any deep-level subdirectory even if you don't have all the intermediary access privileges to directories in between, i.e. all directories above it towards root level .

SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log method has been changed (added Object[] p5):

SLF4J 1.5.11:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Throwable p5 )

SLF4J 1.6.0:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Object[] p5, Throwable p6 )

See compatibility reports for other SLF4J versions on this page.

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

@Bruno Lavit has a great answer, but if you want you can just access the log and download it as txt file to your workspace from the job's URL:

${BUILD_URL}/consoleText

Then it's only a matter of downloading this page to your ${Workspace}

• You can use "Invoke ANT" and use the GET target
• On Linux you can use wget to download it to your workspace
• etc.

Good luck!

Edit: The actual log file on the file system is not on the slave, but kept in the Master machine. You can find it under: $JENKINS_HOME/jobs/$JOB_NAME/builds/lastSuccessfulBuild/log

If you're looking for another build just replace lastSuccessfulBuild with the build you're looking for.

You can use data-image for that. using data-image(data-URI) you can access SVG like inline.

Here is rollover effect using pure CSS and SVG.

        [self.controlState setValue:[NSNumber numberWithBool:YES] forKey:@"SpinnerAnimatingState"];
    }
}

ORDER_BY cast(registration_no as unsigned) ASC

explicitly converts the value to a number. Another possibility to achieve the same would be

ORDER_BY registration_no + 0 ASC

which will force an implicit conversation.

Actually you should check the table definition and change it. You can change the data type to int like this

ALTER TABLE your_table MODIFY COLUMN registration_no int;

In python3 you can use urllib3 and shutil libraires. Download them by using pip or pip3 (Depending whether python3 is default or not)

pip3 install urllib3 shutil

Then run this code

import urllib.request
import shutil

url = "http://www.somewebsite.com/something.pdf"
output_file = "save_this_name.pdf"
with urllib.request.urlopen(url) as response, open(output_file, 'wb') as out_file:
    shutil.copyfileobj(response, out_file)

Note that you download urllib3 but use urllib in code

You can use a combination of other LINQ methods to handle not matching condition:

var res = dictionary.Where(x => x.Value.ID == someID)
                    .Select(x => x.Value.DisplayName)
                    .DefaultIfEmpty("Unknown")
                    .First();

just use android:buttonTint="@color/colorPrimary" attribute on tag, hope it will help

Well, the JVM memory model works something like this: values are stored on one pile of memory stack and objects are stored on another pile of memory called the heap. The garbage collector looks for garbage by looking at a list of objects you've made and seeing which ones aren't pointed at by anything. This is where setting an object to null comes in; all nonprimitive (think of classes) variables are really references that point to the object on the stack, so by setting the reference you have to null the garbage collector can see that there's nothing else pointing at the object and it can decide to garbage collect it. All Java objects are stored on the heap so they can be seen and collected by the garbage collector.

Nonprimitive (ints, chars, doubles, those sort of things) values, however, aren't stored on the heap. They're created and stored temporarily as they're needed and there's not much you can do there, but thankfully the compilers nowadays are really efficient and will avoid needed to store them on the JVM stack unless they absolutely need to.

On a bytecode level, that's basically how it works. The JVM is based on a stack-based machine, with a couple instructions to create allocate objects on the heap as well, and a ton of instructions to manipulate, push and pop values, off the stack. Local variables are stored on the stack, allocated variables on the heap.* These are the heap and the stack I'm referring to above. Here's a pretty good starting point if you want to get into the nitty gritty details.

In the resulting compiled code, there's a bit of leeway in terms of implementing the heap and stack. Allocation's implemented as allocation, there's really not a way around doing so. Thus the virtual machine heap becomes an actual heap, and allocations in the bytecode are allocations in actual memory. But you can get around using a stack to some extent, since instead of storing the values on a stack (and accessing a ton of memory), you can stored them on registers on the CPU which can be up to a hundred times (maybe even a thousand) faster than storing it on memory. But there's cases where this isn't possible (look up register spilling for one example of when this may happen), and using a stack to implement a stack kind of makes a lot of sense.

And quite frankly in your case a few integers probably won't matter. The compiler will probably optimize them out by itself in this case anyways. Optimization should always happen after you get it running and notice it's a tad slower than you'd prefer it to be. Worry about making simple, elegant, working code first then later make it fast (and hopefully) simple, elegant, working code.

Java's actually very nicely made so that you shouldn't have to worry about nulling variables very often. Whenever you stop needing to use something, it will usually incidentally be disappearing from the scope of your program (and thus becoming eligible for garbage collection). So I guess the real lesson here is to use local variables as often as you can.

*There's also a constant pool, a local variable pool, and a couple other things in memory but you have close to no control over the size of those things and I want to keep this fairly simple.

This is what I found as I was plotting only 3 cells from each 4 columns lumped together. My chart has a merged cell with the date which is my x axis. The problem: BC26-BE27 are plotting as ZERO on my chart. enter image description here

I click on the filter on the side of the chart and found where it is showing all the columns for which the data points are charted. I unchecked the boxes that do not have values. enter image description here

It worked for me.

Use Memoize

The op's derivation of state is a direct manipulation of props, with no true derivation needed. In other words, if you have a prop which can be utilized or transformed directly there is no need to store the prop on state.

Given that the state value of start_time is simply the prop start_time.format("HH:mm"), the information contained in the prop is already in itself sufficient for updating the component.

However if you did want to only call format on a prop change, the correct way to do this per latest documentation would be via Memoize: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization

Re-Ordering data Table based on some condition or check box checked. PFB :-

 var tableResult= $('#exampleTable').DataTable();

    var $tr = $(this).closest('tr');
    if ($("#chkBoxId").prop("checked")) 
                    {
                        // re-draw table shorting based on condition
                        tableResult.row($tr).invalidate().order([colindx, 'asc']).draw();
                    }
                    else {
                        tableResult.row($tr).invalidate().order([colindx, "asc"]).draw();
                    }

Use DateTime::createFromFormat like this :

$date = DateTime::createFromFormat('m/d/Y H:i:s', $input_string.' 00:00:00');
$mysql_date_string = $date->format('Y-m-d H:i:s');

You can adapt this to any input format, whereas strtotime() will assume you're using the US date format if you use /, even if you're not.

The added 00:00:00 is because createFromFormat will use the current date to fill missing data, ie : it will take the current hour:min:sec and not 00:00:00 if you don't precise it.

Actually, I found a somewhat quirky way to do this. Add the protocol to your web.config, but inside a location element. Specify the webservice location as the path attribute, like so:

<location path="YourWebservice.asmx">
  <system.web>
    <webServices>
      <protocols>
        <add name="HttpGet"/>
        <add name="HttpPost"/>
      </protocols>
    </webServices>
  </system.web>
</location>

you can add the selected values in an array and set it as the value for default selection

eg:

var selectedItems =[];
selectedItems.push("your selected items");
..
$('#drp_Books_Ill_Illustrations').select2('val',selectedItems );

Try this, this should definitely work!

No command sbt found

It's saying that sbt is not on your path. Try to run ./sbt from ~/bin/sbt/bin or wherever the sbt executable is to verify that it runs correctly. Also check that you have execute permissions on the sbt executable. If this works , then add ~/bin/sbt/bin to your path and sbt should run from anywhere.

See this question about adding a directory to your path.

To verify the path is set correctly use the which command on LINUX. The output will look something like this:

$ which sbt
/usr/bin/sbt

Lastly, to verify sbt is working try running sbt -help or likewise. The output with -help will look something like this:

$ sbt -help
Usage: sbt [options]

  -h | -help         print this message

DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.

    If DataRow.Table.Columns.Contains("column") Then
        MsgBox("YAY")
    End If

To fix, I deleted the app from Simulator.

I also ran Clean first.

I do not think anything orientation-related triggered it. The biggest thing that changed before this symptom started is that a Swift framework started calling NSLog on worker threads instead of main thread.

To create a new object within generic code, you need to refer to the type by its constructor function. So instead of writing this:

function activatorNotWorking<T extends IActivatable>(type: T): T {
    return new T(); // compile error could not find symbol T
}

You need to write this:

function activator<T extends IActivatable>(type: { new(): T ;} ): T {
    return new type();
}

var classA: ClassA = activator(ClassA);

See this question: Generic Type Inference with Class Argument

Open Event Viewer go to window logs->Application and look at the errors prior to this error it will give you the actual error you looking to solve

Alternatively, if generating your markup server-side, you can just fetch and inject. For example, in JSTL you could do this:

<script type="text/javascript">
    <c:import url="https://raw.github.com/mindmup/bootstrap-wysiwyg/master/bootstrap-wysiwyg.js" />
</script>

They don't allow hotlinking for a reason, so probably bad form if you want to be a good citizen. I'd suggest you cache that javascript and only actually re-fetch periodically as you see fit.

If they need to be floated, you could always just set the min-height to 1px so they don't collapse.

You can define a function type in interface in various ways,

1. general way:

export interface IParam {
  title: string;
  callback(arg1: number, arg2: number): number;
}

2. If you would like to use property syntax then,

export interface IParam {
  title: string;
  callback: (arg1: number, arg2: number) => number;
}

3. If you declare the function type first then,

type MyFnType = (arg1: number, arg2: number) => number;

export interface IParam {
  title: string;
  callback: MyFnType;
}

Using is very straight forward,

function callingFn(paramInfo: IParam):number {
    let needToCall = true;
    let result = 0;
   if(needToCall){
     result = paramInfo.callback(1,2);
    }

    return result;
}

4. You can declare a function type literal also , which mean a function can accept another function as it's parameter. parameterize function can be called as callback also.

export interface IParam{
  title: string;
  callback(lateCallFn?:
             (arg1:number,arg2:number)=>number):number;

}

I think it's because there's differences in Application Context and Activity Context, as explained here: http://www.doubleencore.com/2013/06/context/

Which means that we can't show dialog using Application Context. That's it.

Create a class that implements the Runnable interface. Put the code you want to run in the run() method - that's the method that you must write to comply to the Runnable interface. In your "main" thread, create a new Thread class, passing the constructor an instance of your Runnable, then call start() on it. start tells the JVM to do the magic to create a new thread, and then call your run method in that new thread.

public class MyRunnable implements Runnable {

    private int var;

    public MyRunnable(int var) {
        this.var = var;
    }

    public void run() {
        // code in the other thread, can reference "var" variable
    }
}

public class MainThreadClass {
    public static void main(String args[]) {
        MyRunnable myRunnable = new MyRunnable(10);
        Thread t = new Thread(myRunnable)
        t.start();
    }    
}

Take a look at Java's concurrency tutorial to get started.

If your method is going to be called frequently, then it may not be worth creating a new thread each time, as this is an expensive operation. It would probably be best to use a thread pool of some sort. Have a look at Future, Callable, Executor classes in the java.util.concurrent package.

Arrays.asList() method simply returns List type

char [] arr = { 'c','a','t'};    
ArrayList<Character> chars = new ArrayList<Character>();

To add the array into the list, first convert it to list and then call addAll

List arrList = Arrays.asList(arr);
chars.addAll(arrList);

The following line will cause compiler error

chars.addAll(Arrays.asList(arr));

This is a simple question but the answer is surprisingly complex. The short answer is you can do what you're trying to do with std::bind1st or boost::bind. The longer answer is below.

The compiler is correct to suggest you use &CLoggersInfra::RedundencyManagerCallBack. First, if RedundencyManagerCallBack is a member function, the function itself doesn't belong to any particular instance of the class CLoggersInfra. It belongs to the class itself. If you've ever called a static class function before, you may have noticed you use the same SomeClass::SomeMemberFunction syntax. Since the function itself is 'static' in the sense that it belongs to the class rather than a particular instance, you use the same syntax. The '&' is necessary because technically speaking you don't pass functions directly -- functions are not real objects in C++. Instead you're technically passing the memory address for the function, that is, a pointer to where the function's instructions begin in memory. The consequence is the same though, you're effectively 'passing a function' as a parameter.

But that's only half the problem in this instance. As I said, RedundencyManagerCallBack the function doesn't 'belong' to any particular instance. But it sounds like you want to pass it as a callback with a particular instance in mind. To understand how to do this you need to understand what member functions really are: regular not-defined-in-any-class functions with an extra hidden parameter.

For example:

class A {
public:
    A() : data(0) {}
    void foo(int addToData) { this->data += addToData; }

    int data;
};

...

A an_a_object;
an_a_object.foo(5);
A::foo(&an_a_object, 5); // This is the same as the line above!
std::cout << an_a_object.data; // Prints 10!

How many parameters does A::foo take? Normally we would say 1. But under the hood, foo really takes 2. Looking at A::foo's definition, it needs a specific instance of A in order for the 'this' pointer to be meaningful (the compiler needs to know what 'this' is). The way you usually specify what you want 'this' to be is through the syntax MyObject.MyMemberFunction(). But this is just syntactic sugar for passing the address of MyObject as the first parameter to MyMemberFunction. Similarly, when we declare member functions inside class definitions we don't put 'this' in the parameter list, but this is just a gift from the language designers to save typing. Instead you have to specify that a member function is static to opt out of it automatically getting the extra 'this' parameter. If the C++ compiler translated the above example to C code (the original C++ compiler actually worked that way), it would probably write something like this:

struct A {
    int data;
};

void a_init(A* to_init)
{
    to_init->data = 0;
}

void a_foo(A* this, int addToData)
{ 
    this->data += addToData;
}

...

A an_a_object;
a_init(0); // Before constructor call was implicit
a_foo(&an_a_object, 5); // Used to be an_a_object.foo(5);

Returning to your example, there is now an obvious problem. 'Init' wants a pointer to a function that takes one parameter. But &CLoggersInfra::RedundencyManagerCallBack is a pointer to a function that takes two parameters, it's normal parameter and the secret 'this' parameter. That's why you're still getting a compiler error (as a side note: If you've ever used Python, this kind of confusion is why a 'self' parameter is required for all member functions).

The verbose way to handle this is to create a special object that holds a pointer to the instance you want and has a member function called something like 'run' or 'execute' (or overloads the '()' operator) that takes the parameters for the member function, and simply calls the member function with those parameters on the stored instance. But this would require you to change 'Init' to take your special object rather than a raw function pointer, and it sounds like Init is someone else's code. And making a special class for every time this problem comes up will lead to code bloat.

So now, finally, the good solution, boost::bind and boost::function, the documentation for each you can find here:

boost::bind docs, boost::function docs

boost::bind will let you take a function, and a parameter to that function, and make a new function where that parameter is 'locked' in place. So if I have a function that adds two integers, I can use boost::bind to make a new function where one of the parameters is locked to say 5. This new function will only take one integer parameter, and will always add 5 specifically to it. Using this technique, you can 'lock in' the hidden 'this' parameter to be a particular class instance, and generate a new function that only takes one parameter, just like you want (note that the hidden parameter is always the first parameter, and the normal parameters come in order after it). Look at the boost::bind docs for examples, they even specifically discuss using it for member functions. Technically there is a standard function called [std::bind1st][3] that you could use as well, but boost::bind is more general.

Of course, there's just one more catch. boost::bind will make a nice boost::function for you, but this is still technically not a raw function pointer like Init probably wants. Thankfully, boost provides a way to convert boost::function's to raw pointers, as documented on StackOverflow here. How it implements this is beyond the scope of this answer, though it's interesting too.

Don't worry if this seems ludicrously hard -- your question intersects several of C++'s darker corners, and boost::bind is incredibly useful once you learn it.

C++11 update: Instead of boost::bind you can now use a lambda function that captures 'this'. This is basically having the compiler generate the same thing for you.

I was having this same issue in ASP.Net MVC with HttpPostedFilebase and instead of using form on Submit I needed to use button on click where I needed to do some stuff and then if all OK the submit form so here is how I got it working

$(".submitbtn").on("click", function(e) {

    var form = $("#Form");

    // you can't pass Jquery form it has to be javascript form object
    var formData = new FormData(form[0]);

    //if you only need to upload files then 
    //Grab the File upload control and append each file manually to FormData
    //var files = form.find("#fileupload")[0].files;

    //$.each(files, function() {
    //  var file = $(this);
    //  formData.append(file[0].name, file[0]);
    //});

    if ($(form).valid()) {
        $.ajax({
            type: "POST",
            url: $(form).prop("action"),
            //dataType: 'json', //not sure but works for me without this
            data: formData,
            contentType: false, //this is requireded please see answers above
            processData: false, //this is requireded please see answers above
            //cache: false, //not sure but works for me without this
            error   : ErrorHandler,
            success : successHandler
        });
    }
});

this will than correctly populate your MVC model, please make sure in your Model, The Property for HttpPostedFileBase[] has the same name as the Name of the input control in html i.e.

<input id="fileupload" type="file" name="UploadedFiles" multiple>

public class MyViewModel
{
    public HttpPostedFileBase[] UploadedFiles { get; set; }
}

I have a solution of this problem

Install this package:

npm install rxjs@6 rxjs-compat@6 --save

then import this library

import 'rxjs/add/operator/map'

finally restart your ionic project then

ionic serve -l

Put the '$' in front of the text input field, instead of inside it. It makes validation for numeric data a lot easier because you don't have to parse out the '$' after submit.

You can, with JQuery.validate() (or other), add some client-side validation rules that handle currency. That would allow you to have the '$' inside the input field. But you still have to do server-side validation for security and that puts you back in the position of having to remove the '$'.

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

you would call the function like this:

add(3,5)

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

Which would set the variable answer equal to 11 in this case.

Here is how to do it in Unity:

(Modified answer from @markmuetz so be sure to upvote his answer)

int[,] rawNodes = new int[,]
{
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 }
};

private void Start()
{
    int rowLength = rawNodes.GetLength(0);
    int colLength = rawNodes.GetLength(1);
    string arrayString = "";
    for (int i = 0; i < rowLength; i++)
    {
        for (int j = 0; j < colLength; j++)
        {
            arrayString += string.Format("{0} ", rawNodes[i, j]);
        }
        arrayString += System.Environment.NewLine + System.Environment.NewLine;
    }

    Debug.Log(arrayString);
}

In Visual Studio click on one of the fields -> click the light bulb -> Generate Constructors -> Select the fields

Best way is to make function for this

FUNCTION:

$.fn.escape = function (callback) {
    return this.each(function () {
        $(document).on("keydown", this, function (e) {
            var keycode = ((typeof e.keyCode !='undefined' && e.keyCode) ? e.keyCode : e.which);
            if (keycode === 27) {
                callback.call(this, e);
            };
        });
    });
};

EXAMPLE:

$("#my-div").escape(function () {
    alert('Escape!');
})

To determine the class of an object simply call:

someObject.getClass()

You can abbreviate this to someObject.class in most cases. However, if you use this on a Map it will try to retrieve the value with key 'class'. Because of this, I always use getClass() even though it's a little longer.

If you want to check if an object implements a particular interface or extends a particular class (e.g. Date) use:

(somObject instanceof Date)

or to check if the class of an object is exactly a particular class (not a subclass of it), use:

(somObject.getClass() == Date)

Use this :

        List<String> splitString = (List<String>) Arrays.asList(jobtype.split(","));

You can control client cache with HTTP headers. This works in any web framework.

You can set the directives these headers to have fine grained control over how and when to enable|disable cache:

• Cache-Control
• Surrogate-Control
• Expires
• ETag (very good one)
• Pragma (if you want to support old browsers)

Good caching is good, but very complex, in all computer systems. Take a look at https://helmetjs.github.io/docs/nocache/#the-headers for more information.

You can use the "User-Defined Language" option available at the notepad++. You do not need to do the xml-based hacks, where the formatting would be available only in the searched window, with the formatting rules.

Sample for your reference here.

From python >= 3.5 onward, you can use **, glob.iglob(path/**, recursive=True) and it seems the most pythonic solution, i.e.:

import glob, os

for filename in glob.iglob('/pardadox-music/**', recursive=True):
    if os.path.isfile(filename): # filter dirs
        print(filename)

Output:

/pardadox-music/modules/her1.mod
/pardadox-music/modules/her2.mod
...

Notes:
1 - glob.iglob

glob.iglob(pathname, recursive=False)

Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

2 - If recursive is True, the pattern '**' will match any files and zero or more directories and subdirectories.

3 - If the directory contains files starting with . they won’t be matched by default. For example, consider a directory containing card.gif and .card.gif:

>>> import glob
>>> glob.glob('*.gif') ['card.gif'] 
>>> glob.glob('.c*')['.card.gif']

4 - You can also use rglob(pattern), which is the same as calling glob() with **/ added in front of the given relative pattern.

Base on lonesomeday's answer, I create a jpost that wraps certain parameters.

$.extend({
    jpost: function(url, body) {
        return $.ajax({
            type: 'POST',
            url: url,
            data: JSON.stringify(body),
            contentType: "application/json",
            dataType: 'json'
        });
    }
});

Usage:

$.jpost('/form/', { name: 'Jonh' }).then(res => {
    console.log(res);
});

Yes. IE7+ supports attribute selectors:

input[type=radio]
input[type^=ra]
input[type*=d]
input[type$=io]

Element input with attribute type which contains a value that is equal to, begins with, contains or ends with a certain value.

Other safe (IE7+) selectors are:

• Parent > child that has: p > span { font-weight: bold; }
• Preceded by ~ element which is: span ~ span { color: blue; }

Which for <p><span/><span/></p> would effectively give you:

<p>
    <span style="font-weight: bold;">
    <span style="font-weight: bold; color: blue;">
</p>

I'm surprised that everyone else thinks it can't be done. CSS attribute selectors have been here for some time already. I guess it's time we clean up our .css files.

here's a gentle introduction to the js debugger in chrome that i wrote. Maybe it will help others looking for info on this: http://meeech.amihod.com/getting-started-with-javascript-debugging-in-chrome/

Use built-in Exception Handling Middleware

Step 1. In your startup, register your exception handling route:

// It should be one of your very first registrations
app.UseExceptionHandler("/error"); // Add this
app.UseEndpoints(endpoints => endpoints.MapControllers());

Step 2. Create controller that will handle all exceptions and produce error response:

[ApiExplorerSettings(IgnoreApi = true)]
public class ErrorsController : ControllerBase
{
    [Route("error")]
    public MyErrorResponse Error()
    {
        var context = HttpContext.Features.Get<IExceptionHandlerFeature>();
        var exception = context.Error; // Your exception
        var code = 500; // Internal Server Error by default

        if      (exception is MyNotFoundException) code = 404; // Not Found
        else if (exception is MyUnauthException)   code = 401; // Unauthorized
        else if (exception is MyException)         code = 400; // Bad Request

        Response.StatusCode = code; // You can use HttpStatusCode enum instead

        return new MyErrorResponse(exception); // Your error model
    }
}

A few important notes and observations:

• [ApiExplorerSettings(IgnoreApi = true)] is needed. Otherwise, it may break your Swashbuckle swagger
• Again, app.UseExceptionHandler("/error"); has to be one of the very top registrations in your Startup Configure(...) method. It's probably safe to place it at the top of the method.
• The path in app.UseExceptionHandler("/error") and in controller [Route("error")] should be the same, to allow the controller handle exceptions redirected from exception handler middleware.

Microsoft documentation for this subject is not that great but has some interesting ideas. I'll just leave the link here.

Response models and custom exceptions

Implement your own response model and exceptions. This example is just a good starting point. Every service would need to handle exceptions in its own way. But with this code, you have full flexibility and control over handling exceptions and returning a proper result to the caller.

An example of error response model (just to give you some ideas):

public class MyErrorResponse
{
    public string Type { get; set; }
    public string Message { get; set; }
    public string StackTrace { get; set; }

    public MyErrorResponse(Exception ex)
    {
        Type = ex.GetType().Name;
        Message = ex.Message;
        StackTrace = ex.ToString();
    }
}

For simpler services, you might want to implement http status code exception that would look like this:

public class HttpStatusException : Exception
{
    public HttpStatusCode Status { get; private set; }

    public HttpStatusException(HttpStatusCode status, string msg) : base(msg)
    {
        Status = status;
    }
}

This can be thrown like that:

throw new HttpStatusCodeException(HttpStatusCode.NotFound, "User not found");

Then your handling code could be simplified to:

if (exception is HttpStatusException httpException)
{
    code = (int) httpException.Status;
}

Why so un-obvious HttpContext.Features.Get<IExceptionHandlerFeature>()?

ASP.NET Core developers embraced the concept of middlewares where different aspects of functionality such as Auth, Mvc, Swagger etc. are separated and executed sequentially by processing the request and returning the response or passing the execution to the next middleware. With this architecture, MVC itself, for instance, would not be able to handle errors happening in Auth. So, they came up with exception handling middleware that catches all the exceptions happening in middlewares registered down in the pipeline, pushes exception data into HttpContext.Features, and re-runs the pipeline for specified route (/error), allowing any middleware to handle this exception, and the best way to handle it is by our Controllers to maintain proper content negotiation.

Here is a sample to find if there are match elements in another list

List<int> nums1 = new List<int> { 2, 4, 6, 8, 10 };
List<int> nums2 = new List<int> { 1, 3, 6, 9, 12};

if (nums1.Any(x => nums2.Any(y => y == x)))
{
    Console.WriteLine("There are equal elements");
}
else
{
    Console.WriteLine("No Match Found!");
}

I prefer to process collections functionally rather than mutate them in place. That avoids this kind of problem altogether, as well as aliasing issues and other tricky sources of bugs.

So, I would implement it like:

List<Thing> expand(List<Thing> inputs) {
    List<Thing> expanded = new ArrayList<Thing>();

    for (Thing thing : inputs) {
        expanded.add(thing);
        if (needsSomeMoreThings(thing)) {
            addMoreThingsTo(expanded);
        }
    }

    return expanded;
}

SHGetKnownFolderPath:

Retrieves the full path of a known folder identified by the folder's KNOWNFOLDERID.

And, FOLDERID_CommonStartup:

Default Path %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\StartUp

There are also managed equivalents, but you haven't told us what you're programming in.

Give your image an id. Then you can do this in your javascript.

document.getElementById("blaah").src="blaah";

You can use the ".___" method to change the value of any attribute of any element.

A root-relative URL starts with a / character, to look something like <a href="/directoryInRoot/fileName.html">link text</a>.

The link you posted: <a href="fruits/index.html">Back to Fruits List</a> is linking to an html file located in a directory named fruits, the directory being in the same directory as the html page in which this link appears.

To make it a root-relative URL, change it to:

<a href="/fruits/index.html">Back to Fruits List</a>

Edited in response to question, in comments, from OP:

So doing / will make it relative to www.example.com, is there a way to specify what the root is, e.g what if i want the root to be www.example.com/fruits in www.example.com/fruits/apples/apple.html?

Yes, prefacing the URL, in the href or src attributes, with a / will make the path relative to the root directory. For example, given the html page at www.example.com/fruits/apples.html, the a of href="/vegetables/carrots.html" will link to the page www.example.com/vegetables/carrots.html.

The base tag element allows you to specify the base-uri for that page (though the base tag would have to be added to every page in which it was necessary for to use a specific base, for this I'll simply cite the W3's example:

For example, given the following BASE declaration and A declaration:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<HTML>
 <HEAD>
   <TITLE>Our Products</TITLE>
   <BASE href="http://www.aviary.com/products/intro.html">
 </HEAD>

 <BODY>
   <P>Have you seen our <A href="../cages/birds.gif">Bird Cages</A>?
 </BODY>
</HTML>

the relative URI "../cages/birds.gif" would resolve to:

http://www.aviary.com/cages/birds.gif

Example quoted from: http://www.w3.org/TR/html401/struct/links.html#h-12.4.

I had the same error message, and the problem was also the metadata part of the connection string, but I had to dig a little deeper to solve it and wanted to share this little nugget:

The metadata string is made up of three sections that each look like this:

res://
      (assembly)/
      (model name).(ext)

Where ext is "csdl", "ssdl", and "msl".

For most people, assembly can probably be "*", which seems to indicate that all loaded assemblies will be searched (I haven't done a huge amount of testing of this). This part wasn't an issue for me, so I can't comment on whether you need the assembly name or file name (i.e., with or without ".dll"), though I have seen both suggested.

The model name part should be the name and namespace of your .edmx file, relative to your assembly. So if you have a My.DataAccess assembly and you create DataModels.edmx in a Models folder, its full name is My.DataAccess.Models.DataModels. In this case, you would have "Models.DataModels.(ext)" in your metadata.

If you ever move or rename your .edmx file, you will need to update your metadata string manually (in my experience), and remembering to change the relative namespace will save a few headaches.

If you have a QMainWindow you can override closeEvent method.

#include <QCloseEvent>
void MainWindow::closeEvent (QCloseEvent *event)
{
    QMessageBox::StandardButton resBtn = QMessageBox::question( this, APP_NAME,
                                                                tr("Are you sure?\n"),
                                                                QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
                                                                QMessageBox::Yes);
    if (resBtn != QMessageBox::Yes) {
        event->ignore();
    } else {
        event->accept();
    }
}

If you're subclassing a QDialog, the closeEvent will not be called and so you have to override reject():

void MyDialog::reject()
{
    QMessageBox::StandardButton resBtn = QMessageBox::Yes;
    if (changes) {
        resBtn = QMessageBox::question( this, APP_NAME,
                                        tr("Are you sure?\n"),
                                        QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
                                        QMessageBox::Yes);
    }
    if (resBtn == QMessageBox::Yes) {
        QDialog::reject();
    }
}

Also note that if the textSize is set in code, calling textView.setTextSize(X) interprets the number (X) as SP. Use setTextSize(TypedValue.COMPLEX_UNIT_DIP, X) to set values in dp.

I guess you probably are running the preview of VS2013 Ultimate, because it is not present in my professional preview. But looking online I found that the feature is called Code Information Indicators or CodeLens, and can be located under

Tools ? Options ? Text Editor ? All Languages ? CodeLens

(for RC/final version)

or

Tools ? Options ? Text Editor ? All Languages ? Code Information Indicators

(for preview version)

That was according to this link. It seems to be pretty well hidden.

In Visual Studio 2013 RTM, you can also get to the CodeLens options by right clicking the indicators themselves in the editor:

documented in the Q&A section of the msdn CodeLens documentation

eval: This is very powerful, but is also very dangerous if you accept strings to evaluate from untrusted input. Suppose the string being evaluated is "os.system('rm -rf /')" ? It will really start deleting all the files on your computer.

ast.literal_eval: Safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, None, bytes and sets.

Syntax:

eval(expression, globals=None, locals=None)
import ast
ast.literal_eval(node_or_string)

Example:

# python 2.x - doesn't accept operators in string format
import ast
ast.literal_eval('[1, 2, 3]')  # output: [1, 2, 3]
ast.literal_eval('1+1') # output: ValueError: malformed string


# python 3.0 -3.6
import ast
ast.literal_eval("1+1") # output : 2
ast.literal_eval("{'a': 2, 'b': 3, 3:'xyz'}") # output : {'a': 2, 'b': 3, 3:'xyz'}
# type dictionary
ast.literal_eval("",{}) # output : Syntax Error required only one parameter
ast.literal_eval("__import__('os').system('rm -rf /')") # output : error

eval("__import__('os').system('rm -rf /')") 
# output : start deleting all the files on your computer.
# restricting using global and local variables
eval("__import__('os').system('rm -rf /')",{'__builtins__':{}},{})
# output : Error due to blocked imports by passing  '__builtins__':{} in global

# But still eval is not safe. we can access and break the code as given below
s = """
(lambda fc=(
lambda n: [
    c for c in 
        ().__class__.__bases__[0].__subclasses__() 
        if c.__name__ == n
    ][0]
):
fc("function")(
    fc("code")(
        0,0,0,0,"KABOOM",(),(),(),"","",0,""
    ),{}
)()
)()
"""
eval(s, {'__builtins__':{}})

In the above code ().__class__.__bases__[0] nothing but object itself. Now we instantiated all the subclasses, here our main enter code hereobjective is to find one class named n from it.

We need to code object and function object from instantiated subclasses. This is an alternative way from CPython to access subclasses of object and attach the system.

From python 3.7 ast.literal_eval() is now stricter. Addition and subtraction of arbitrary numbers are no longer allowed. link

Here is the python snippet you need to upload one large single file as multipart formdata. With NodeJs Multer middleware running on the server side.

import requests
latest_file = 'path/to/file'
url = "http://httpbin.org/apiToUpload"
files = {'fieldName': open(latest_file, 'rb')}
r = requests.put(url, files=files)

For the server side please check the multer documentation at: https://github.com/expressjs/multer here the field single('fieldName') is used to accept one single file, as in:

var upload = multer().single('fieldName');

This works for MVC 5:

<a href="@Url.Action("ActionName", "ControllerName", new { paramName1 = item.paramValue1, paramName2 = item.paramValue2 })" >
    Link text
</a>

we can easily print the current time and date using echo and system variables as below.

echo %DATE% %TIME%

output example: 13-Sep-19 15:53:05.62

Since the answers deviate I decided to test this and post the result - including the test example.

The server here just writes data to a client and does not expect any input.

The server:

ServerSocket serverSocket = new ServerSocket(4444);
Socket clientSocket = serverSocket.accept();
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
while (true) {
  out.println("output");
  if (out.checkError()) System.out.println("ERROR writing data to socket !!!");
  System.out.println(clientSocket.isConnected());
  System.out.println(clientSocket.getInputStream().read());
        // thread sleep ...
  // break condition , close sockets and the like ...
}

• clientSocket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• out.checkError() is true as soon as the client is disconnected so I recommend this

You can use something like this:
note: responseText returns server response and statusText returns the predefined
message for status error.for e.g:
responseText returns something like "Not Found (#404)" in some frameworks like Yii2 but
statusText returns "Not Found".

$.ajax({
    cache: false,
    url: "addInterview_Code.asp",
    type: "POST",
    datatype: "text",
    data: strData,
    success: function (html) {
        alert('successful : ' + html);
        $("#result").html("Successful");
    },
    error: function (data) {
        console.log(data.status + ':' + data.statusText,data.responseText);
    }
});

Based on the current user's latitude, longitude and the distance you wants to find,the sql query is given below.

SELECT * FROM(
    SELECT *,(((acos(sin((@latitude*pi()/180)) * sin((Latitude*pi()/180))+cos((@latitude*pi()/180)) * cos((Latitude*pi()/180)) * cos(((@longitude - Longitude)*pi()/180))))*180/pi())*60*1.1515*1.609344) as distance FROM Distances) t
WHERE distance <= @distance

@latitude and @longitude are the latitude and longitude of the point. Latitude and longitude are the columns of distances table. Value of pi is 22/7

The more general extension of ViewPager would be to create a SetPagingEnabled method so that we can enable and disable paging on the fly. To enable / disable the swiping, just overide two methods: onTouchEvent and onInterceptTouchEvent. Both will return "false" if the paging was disabled.

public class CustomViewPager extends ViewPager {

    private boolean enabled;

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.enabled = true;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onTouchEvent(event);
        }

        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onInterceptTouchEvent(event);
        }

        return false;
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    } 
}

Then select this instead of the built-in viewpager in XML

<mypackage.CustomViewPager 
    android:id="@+id/myViewPager" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent" />

You just need to call the setPagingEnabled method with false and users won't be able to swipe to paginate.

Getting stacktrace:

StackTraceElement[] ste = Thread.currentThread().getStackTrace();

Printing stacktrace (JAVA 8+):

Arrays.asList(ste).forEach(System.out::println);

Printing stacktrage (JAVA 7):

StringBuilder sb = new StringBuilder();

for (StackTraceElement st : ste) {
    sb.append(st.toString() + System.lineSeparator());
}
System.out.println(sb);

    @echo off

    (echo this is in the first line) > xy.txt
    (echo this is in the second line) >> xy.txt

    exit

The two >> means that the second line will be appended to the file (i.e. second line will start after the last line of xy.txt).

this is how the xy.txt looks like:

this is in the first line
this is in the second line

The answer below is related to this deprecation warning occurring in the Fragments tutorial on the Android developer website and may not be related to the posts above.

I used this code on the tutorial lesson and it did worked.

public void onAttach(Context context){
    super.onAttach(context);

    Activity activity = getActivity();

I was worried that activity maybe null as what the documentation states.

getActivity

FragmentActivity getActivity () Return the FragmentActivity this fragment is currently associated with. May return null if the fragment is associated with a Context instead.

But the onCreate on the main_activity clearly shows that the fragment was loaded and so after this method, calling get activity from the fragment will return the main_activity class.

getSupportFragmentManager().beginTransaction() .add(R.id.fragment_container, firstFragment).commit();

I hope I am correct with this. I am an absolute newbie.

While installing the node modules for mocha I had tried the below commands

• npm install
• npm install mocha
• npm install --save-dev mocha
• npm install mocha -g # to install it globally also

and on running or executing the mocha test I was trying

• mocha test
• npm run test
• mocha test test\index.test.js
• npm test

but I was getting the below error as:

'Mocha' is not recognized as internal or external command

So , after trying everything it came out to be just set the path to environment variables under the System Variables as:

C:\Program Files\nodejs\

and it worked :)

try this one ,

n=int(raw_input("Enter length of the list"))
l1=[]
for i in range(n):
    a=raw_input()
    if(a.isdigit()):
        l1.insert(i,float(a)) #statement1
    else:
        l1.insert(i,a)        #statement2

If the element of the list is just a number the statement 1 will get executed and if it is a string then statement 2 will be executed. In the end you will have an list l1 as you needed.

I just want to suggest another way to add an option. Instead of setting the value and text as a string one can also do:

var option = $('<option/>')
                  .val('option5')
                  .text('option5');

$('#selectBox').append(option);

This is a less error-prone solution when adding options' values and texts dynamically.

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

You could:

SELECT COALESCE(SUM(columnA), 0) FROM my_table WHERE columnB = 1
INTO res;

This happens to work, because your query has an aggregate function and consequently always returns a row, even if nothing is found in the underlying table.

Plain queries without aggregate would return no row in such a case. COALESCE would never be called and couldn't save you. While dealing with a single column we can wrap the whole query instead:

SELECT COALESCE( (SELECT columnA FROM my_table WHERE ID = 1), 0)
INTO res;

Works for your original query as well:

SELECT COALESCE( (SELECT SUM(columnA) FROM my_table WHERE columnB = 1), 0)
INTO res;

More about COALESCE() in the manual.
More about aggregate functions in the manual.
More alternatives in this later post:

• How to return a value from a function if no value is found

Here is pythonic way to do it. This function will allow you to loop through key-value pair in all the levels. It does not save the whole thing to the memory but rather walks through the dict as you loop through it

def recursive_items(dictionary):
    for key, value in dictionary.items():
        if type(value) is dict:
            yield (key, value)
            yield from recursive_items(value)
        else:
            yield (key, value)

a = {'a': {1: {1: 2, 3: 4}, 2: {5: 6}}}

for key, value in recursive_items(a):
    print(key, value)

Prints

a {1: {1: 2, 3: 4}, 2: {5: 6}}
1 {1: 2, 3: 4}
1 2
3 4
2 {5: 6}
5 6

Try Following code

if line.startswith("Path="): return line[5:]

teststr=$'test1\n'
teststr+=$'test2\n'
echo "$teststr"

SQL is expecting the GUID as a string. The following in C# returns a string Sql is expecting.

"'" + Guid.NewGuid().ToString() + "'"

Something like

INSERT INTO TABLE (GuidID) VALUE ('4b5e95a7-745a-462f-ae53-709a8583700a')

is what it should look like in SQL.

If you want to use shell scripting and not rely on non-posix extensions (such as so-called bashisms), you can use techniques that do not require forking external tools such as grep, sed, cut, awk, etc., which then make your script less efficient. Maybe efficiency and posix portability is not important in your use case. But in case it is (or just as a good habit), you can use the following parameter expansion option method to extract the first two characters of a shell variable:

$ sh -c 'var=abcde; echo "${var%${var#??}}"'
ab

This uses "smallest prefix" parameter expansion to remove the first two characters (this is the ${var#??} part), then "smallest suffix" parameter expansion (the ${var% part) to remove that all-but-the-first-two-characters string from the original value.

This method was previously described in this answer to the "Shell = Check if variable begins with #" question. That answer also describes a couple similar parameter expansion methods that can be used in a slightly different context that the one that applies to the original question here.

I just ran into this question and, while it is old, I figured I'd add an answer for the archives. The OP asked about for loops, but their goal was to gather a random sample of rows from the table. For that task, Postgres 9.5+ offers the TABLESAMPLE clause on WHERE. Here's a good rundown:

https://www.2ndquadrant.com/en/blog/tablesample-in-postgresql-9-5-2/

I tend to use Bernoulli as it's row-based rather than page-based, but the original question is about a specific row count. For that, there's a built-in extension:

https://www.postgresql.org/docs/current/tsm-system-rows.html

CREATE EXTENSION tsm_system_rows;

Then you can grab whatever number of rows you want:

select * from playtime tablesample system_rows (15);

$shorttext = preg_replace('/^([\s\S]{1,200})[\s]+?[\s\S]+/', '$1', $fulltext);

Description:

• ^ - start from beginning of string
• ([\s\S]{1,200}) - get from 1 to 200 of any character
• [\s]+? - not include spaces at the end of short text so we can avoid word ... instead of word...
• [\s\S]+ - match all other content

Tests:

1. regex101.com let's add to or few other r
2. regex101.com orrrr exactly 200 characters.
3. regex101.com after fifth r orrrrr excluded.

Enjoy.

Where the variable map is an object of type GMap2:

    GEvent.addListener(map, "tilesloaded", function() {
      console.log("Map is fully loaded");
    });

The exec(3,3p) functions replace the current process with another. That is, the current process stops, and another runs instead, taking over some of the resources the original program had.

Use the Take method:

var foo = (from t in MyTable
           select t.Foo).Take(10);

In VB LINQ has a take expression:

Dim foo = From t in MyTable _
          Take 10 _
          Select t.Foo

From the documentation:

Take<TSource> enumerates source and yields elements until count elements have been yielded or source contains no more elements. If count exceeds the number of elements in source, all elements of source are returned.

Reloading the configuration file (my.cnf) cannot be done without restarting the mysqld server.

FLUSH LOGS only rotates a few log files.

SET @@...=... sets it for anyone not yet logged in, but it will go away after the next restart. But that gives a clue... Do the SET, and change my.cnf; that way you are covered. Caveat: Not all settings can be performed via SET.

SET PERSIST ... will set the global setting and save it past restarts. Nearly all settings can be adjusted this way.

EDIT

In one of the older projects I have found a simple log4j.properties file:

# For the general syntax of property based configuration files see
# the documentation of org.apache.log4j.PropertyConfigurator.

# The root category uses two appenders: default.out and default.file.
# The first one gathers all log output, the latter only starting with 
# the priority INFO.
# The root priority is DEBUG, so that all classes can be logged unless 
# defined otherwise in more specific properties.
log4j.rootLogger=DEBUG, default.out, default.file

# System.out.println appender for all classes
log4j.appender.default.out=org.apache.log4j.ConsoleAppender
log4j.appender.default.out.threshold=DEBUG
log4j.appender.default.out.layout=org.apache.log4j.PatternLayout
log4j.appender.default.out.layout.ConversionPattern=%-5p %c: %m%n

log4j.appender.default.file=org.apache.log4j.FileAppender
log4j.appender.default.file.append=true
log4j.appender.default.file.file=/log/mylogfile.log
log4j.appender.default.file.threshold=INFO
log4j.appender.default.file.layout=org.apache.log4j.PatternLayout
log4j.appender.default.file.layout.ConversionPattern=%-5p %c: %m%n

It looks like there's something else called Afisho_rankimin in your DB so the function is not being created. Try calling your function something else. E.g.

CREATE FUNCTION dbo.Afisho_rankimin1(@emri_rest int)
RETURNS int
AS
   BEGIN
       Declare @rankimi int
       Select @rankimi=dbo.RESTORANTET.Rankimi
       From RESTORANTET
       Where  dbo.RESTORANTET.ID_Rest=@emri_rest
       RETURN @rankimi
  END
  GO

Note that you need to call this only once, not every time you call the function. After that try calling

SELECT dbo.Afisho_rankimin1(5) AS Rankimi 

It is because value coming String (Java Date object constructor for getting string is deprecated)

and Date(String) is deprecated.

Have a look at jodatime or you could put @SuppressWarnings({“deprecation”}) outside the method calling the Date(String) constructor.

Maybe change the number input with javascript to text input when you don't want a spinner;

document.getElementById('myinput').type = 'text';

and stop the user entering text;

  document.getElementById('myinput').onkeydown = function(e) {
  if(!((e.keyCode > 95 && e.keyCode < 106)
    || (e.keyCode > 47 && e.keyCode < 58) 
    || e.keyCode == 8
    || e.keyCode == 9)) {
          return false;
      }
  }

then have the javascript change it back in case you do want a spinner;

document.getElementById('myinput').type = 'number';

it worked well for my purposes

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:

const numFormatter = new Intl.NumberFormat('en-US', {
  style: "decimal",
  maximumFractionDigits: 2
})

// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123

// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24

// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN

// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN

Use the international date local via format. This cleans up any bad inputs, if there is one it returns a string of NaN you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace.

ParseFloat converts the this type definition from string to number

If you use React, this is what your calculate function could look like:

updateCalculationInput = (e) => {
    let value;
    value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
    if(value === 'NaN') return; // locale returns string of NaN if fail
    value = value.replace(/,/g, ""); // remove commas
    value = parseFloat(value); // now parse to float should always be clean input

    // Do the actual math and setState calls here
}

<script type="text/javascript">
        function returnwasset(){
            alert('return sent');
            $.ajax({
                type: "POST",
                url: "process.php",
                data: somedata;
                dataType:'text'; //or HTML, JSON, etc.
                success: function(response){
                    alert(response);
                    //echo what the server sent back...
                }
            });
        }
    </script>

With position fixed, you need to provide values to set where the div will be placed, since it's a fixed position.

Something like....

.test
{
   position:fixed;
   left:100px;
   top:150px;
}

Fixed - Generates an absolutely positioned element, positioned relative to the browser window. The element's position is specified with the "left", "top", "right", and "bottom" properties

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

this would be good log4j error/exception logging - readable by splunk/other logging/monitoring s/w. everything is form of key-value pair. log4j would get the stack trace from Exception obj e

    try {
          ---
          ---
    } catch (Exception e) {
        log.error("api_name={} method={} _message=\"error description.\" msg={}", 
                  new Object[]{"api_name", "method_name", e.getMessage(), e});
    }

Yes. A structure is just like a class, but defaults to public:, in the class definition and when inheriting:

struct Foo
{
    int bar;

    Foo(void) :
    bar(0)
    {
    }
}

Considering your other question, I would suggest you read through some tutorials. They will answer your questions faster and more complete than we will.

Thanks Sanoj, that worked for me.
However iOS does not support "onbeforeunload" on iPhone. Workaround for me was to set localStorage with js:

<button onclick="myFunction()">Click me</button>

<script>
document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });
function myFunction() {
  localStorage.setItem('scrollpos', window.scrollY);
  location.reload(); 
}
</script>

I think the problem may be that you are not finding your element because of the "#" in your call to get it:

window.parent.document.getElementById('#target'); 

You only need the # if you are using jquery. Here it should be:

window.parent.document.getElementById('target'); 

floor() will go down.

ceil() will go up.

round() will go to nearest by default.

Divide by 10, do the ceil, then multiply by 10 to reduce the significant digits.

$number = ceil($input / 10) * 10;

Edit: I've been doing it this way for so long.. but TallGreenTree's answer is cleaner.

If you want to return to your current working directory:

current_dir=$PWD;cd /path/to/your/command/dir;special command ARGS;cd $current_dir;

1. We are setting a variable current_dir equal to your pwd
2. after that we are going to cd to where you need to run your command
3. then we are running the command
4. then we are going to cd back to our variable current_dir

If you have JQuery loaded already, you can just do this:

$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');

EDIT:

First load JQuery in the head tag:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

Then call the Javascript to change the background image when something happens on the page, like when it finishes loading:

<script type="text/javascript">
    $(document).ready(function() {
        $('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
    });
</script>

Easy and safe - make new stream from original source:

XML Schema requires that the xml namespace be declared and imported before using xml:lang (and other xml namespace values) RELAX NG predeclares the xml namespace, as in XML, so no additional declaration is needed.

You need to setup a SDK for Java projects, like @rizzletang said, but you don't need to create a new project, you can do it from the Welcome screen.

On the bottom right, select Configure > Project Defaults > Project Structure:

Picking the Project tab on the left will show that you have no SDK selected:

Just click the New... button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should just show up.

You can get a JSON file that maps country codes to phone codes from http://country.io/phone.json:

...
BD: "880",
BE: "32",
BF: "226",
BG: "359",
BA: "387",
...

If you want country names then http://country.io/names.json will give you that:

...
"AL": "Albania",
"AM": "Armenia",
"AO": "Angola",
"AQ": "Antarctica",
"AR": "Argentina",
...

See http://country.io/data for more details.

You can use strtotime() to achieve this:

$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', strtotime($now))); // $now + 3 hours

Example below returns value of $name_of_var

var=name_of_var
echo $(eval echo "\$$var")

I found this to work really well if you want to count rows without counting the th and any rows from tables inside of tables:

var rowCount = $("#tableData > tbody").children().length;

Check out java.io.ByteArrayInputStream

The most straightforward way:

long millisInDay = 60 * 60 * 24 * 1000;
long currentTime = new Date().getTime();
long dateOnly = (currentTime / millisInDay) * millisInDay;
Date clearDate = new Date(dateOnly);

The runtime splits the arguments given at the console at each space.

If you call

myApp.exe arg1 arg2 arg3

The Main Method gets an array of

var args = new string[] {"arg1","arg2","arg3"}

To gzip up your font files as well!

add "x-font/otf x-font/ttf x-font/eot"

as in:

AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml x-font/otf x-font/ttf x-font/eot

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

You could add the time component

WHERE mydate<='2008-11-25 23:59:59'

but that might fail on DST switchover dates if mydate is '2008-11-25 24:59:59', so it's probably safest to grab everything before the next date:

WHERE mydate < '2008-11-26 00:00:00'

Stop abusing private fields!!!

The comments here seem to be overwhelmingly supportive towards using private fields. Well, then I have something different to say.

Are private fields good in principle? Yes. But saying that a golden rule is make everything private when you're not sure is definitely wrong! You won't see the problem until you run into one. In my opinion, you should mark fields as protected if you're not sure.

There are two cases you want to extend a class:

• You want to add extra functionality to a base class
• You want to modify existing class that's outside the current package (in some libraries perhaps)

There's nothing wrong with private fields in the first case. The fact that people are abusing private fields makes it so frustrating when you find out you can't modify shit.

Consider a simple library that models cars:

class Car {
    private screw;
    public assembleCar() {
       screw.install();
    };
    private putScrewsTogether() {
       ...
    };
}

The library author thought: there's no reason the users of my library need to access the implementation detail of assembleCar() right? Let's mark screw as private.

Well, the author is wrong. If you want to modify only the assembleCar() method without copying the whole class into your package, you're out of luck. You have to rewrite your own screw field. Let's say this car uses a dozen of screws, and each of them involves some untrivial initialization code in different private methods, and these screws are all marked private. At this point, it starts to suck.

Yes, you can argue with me that well the library author could have written better code so there's nothing wrong with private fields. I'm not arguing that private field is a problem with OOP. It is a problem when people are using them.

The moral of the story is, if you're writing a library, you never know if your users want to access a particular field. If you're unsure, mark it protected so everyone would be happier later. At least don't abuse private field.

I very much support Nick's answer.

The map() function is there to apply the same procedure to every item in an iterable data structure, like lists, generators, strings, and other stuff.

Let's look at an example: map() can iterate over every item in a list and apply a function to each item, than it will return (give you back) the new list.

Imagine you have a function that takes a number, adds 1 to that number and returns it:

def add_one(num):
  new_num = num + 1
  return new_num

You also have a list of numbers:

my_list = [1, 3, 6, 7, 8, 10]

if you want to increment every number in the list, you can do the following:

>>> map(add_one, my_list)
[2, 4, 7, 8, 9, 11]

Note: At minimum map() needs two arguments. First a function name and second something like a list.

Let's see some other cool things map() can do. map() can take multiple iterables (lists, strings, etc.) and pass an element from each iterable to a function as an argument.

We have three lists:

list_one = [1, 2, 3, 4, 5]
list_two = [11, 12, 13, 14, 15]
list_three = [21, 22, 23, 24, 25]

map() can make you a new list that holds the addition of elements at a specific index.

Now remember map(), needs a function. This time we'll use the builtin sum() function. Running map() gives the following result:

>>> map(sum, list_one, list_two, list_three)
[33, 36, 39, 42, 45]

REMEMBER:
In Python 2 map(), will iterate (go through the elements of the lists) according to the longest list, and pass None to the function for the shorter lists, so your function should look for None and handle them, otherwise you will get errors. In Python 3 map() will stop after finishing with the shortest list. Also, in Python 3, map() returns an iterator, not a list.

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

defineProperty is a method on Object which allow you to configure the properties to meet some criterias. Here is a simple example with an employee object with two properties firstName & lastName and append the two properties by overriding the toString method on the object.

var employee = {
    firstName: "Jameel",
    lastName: "Moideen"
};
employee.toString=function () {
    return this.firstName + " " + this.lastName;
};
console.log(employee.toString());

You will get Output as : Jameel Moideen

I am going to change the same code by using defineProperty on the object

var employee = {
    firstName: "Jameel",
    lastName: "Moideen"
};
Object.defineProperty(employee, 'toString', {
    value: function () {
        return this.firstName + " " + this.lastName;
    },
    writable: true,
    enumerable: true,
    configurable: true
});
console.log(employee.toString());

The first parameter is the name of the object and then second parameter is name of the property we are adding , in our case it’s toString and then the last parameter is json object which have a value going to be a function and three parameters writable,enumerable and configurable.Right now I just declared everything as true.

If u run the example you will get Output as : Jameel Moideen

Let’s understand why we need the three properties such as writable,enumerable and configurable.

writable

One of the very annoying part of the javascript is , if you change the toString property to something else for example

if you run this again , everything gets breaks. Let’s change writable to false. If run the same again you will get the correct output as ‘Jameel Moideen’ . This property will prevent overwrite this property later.

enumerable

if you print all the keys inside the object , you can see all the properties including toString.

console.log(Object.keys(employee));

if you set enumerable to false , you can hide toString property from everybody else. If run this again you will get firstName,lastName

configurable

if someone later redefined the object on later for example enumerable to true and run it. You can see toString property came again.

var employee = {
    firstName: "Jameel",
    lastName: "Moideen"
};
Object.defineProperty(employee, 'toString', {
    value: function () {
        return this.firstName + " " + this.lastName;
    },
    writable: false,
    enumerable: false,
    configurable: true
});

//change enumerable to false
Object.defineProperty(employee, 'toString', {

    enumerable: true
});
employee.toString="changed";
console.log(Object.keys(employee));

you can restrict this behavior by set configurable to false.

You convert the hex string to a byte array.

public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
                 .Where(x => x % 2 == 0)
                 .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                 .ToArray();
}

And then use WriteAllBytes to write to the file system.

A simplified version of Darin Dimitrov's first solution:

public string GetDomainName<T>()
{
    var dnAttribute = typeof(T).GetCustomAttribute<DomainNameAttribute>(true);
    if (dnAttribute != null)
    {
        return dnAttribute.Name;
    }
    return null;
}

Another way is to use TRANSLATE:

TRANSLATE (col_name, 'x'||CHR(10)||CHR(13), 'x')

The 'x' is any character that you don't want translated to null, because TRANSLATE doesn't work right if the 3rd parameter is null.

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

Solution with System.Threading.Timer:

    private void nameOfMethod()
    {
        //do something
    }

    /// <summary>
    /// run method at 22:00 every day
    /// </summary>
    private void runMethodEveryDay()
    {
        var runAt = DateTime.Today + TimeSpan.FromHours(22);

        if(runAt.Hour>=22)
            runAt = runAt.AddDays(1.00d); //if aplication is started after 22:00 

        var dueTime = runAt - DateTime.Now; //time before first run ; 

        long broj3 = (long)dueTime.TotalMilliseconds;
        TimeSpan ts2 = new TimeSpan(24, 0, 1);//period of repeating method
        long broj4 = (long)ts2.TotalMilliseconds;
        timer2 = new System.Threading.Timer(_ => nameOfMethod(), null, broj3, broj4);
    }

instead of overwriting, create it as different css and call it in your element as other css(multiple css).
Something like:

.flex-control-thumbs li 
{ margin: 0; }

Internal CSS:

.additional li
{width: 25%; float: left;}

<ul class="flex-control-thumbs additional"> </ul> /* assuming parent is ul */

[explanations in my “main answer”]

line 7. section around the whole website? Or only a div?

Neither. For styling: use the <body>, it’s already there. For sectioning/semantics: as detailed in my example HTML its effect is contrary to usefulness. Extra wrappers to already wrapped content is no improvement, but noise.

line 8. Each section start with a header?

No, it is the author’s choice where to put content typically summarized as “header”. And if that header-content is clearly recognizable without extra marking, it may perfectly stay without <header>. This is also the author’s choice.

line 23. Is this div right? or must this be a section?

The <div> is probably wrong. It depends on the intentions: is it for styling only it could be right. If it’s for semantic purposes it is wrong: it should be an <article> instead as shown in my other answer. <article> is also right if it is for both styling and sectioning combined.

<section> looks wrong here, as there are no similar sections before or after this one, like chapters in a book. (This is the purpose of <section>).

line 24. Split left/right column with a div.

No. Why?

line 25. Right place for the article tag?

Yes, makes sense.

line 26. Is it required to put your h1-tag in the header-tag?

No. A lone <h*> element probably never needs to go in a <header> (but it can if you want to) as it is already clear that it’s the heading of what is about to come. – It would make sense if that <header> also encompassed a tagline (marked with <p>), for example.

line 43. The content is not related to the main article, so I decided this is a section and not an aside.

It is a misunderstanding that an <aside> has to be “tangentially related” to the content around. The point is: use an <aside> if the content is only “tangentially related” or not at all!

Nevertheless, apart from <aside> being a decent choice, <article> might still be better than a <section> as “hot items” and “new items” are not to be read like two chapters in a book. You can perfectly go for one of them and not the other like an alternative sorting of something, not like two parts of a whole.

line 44. H2 without header

Is great.

line 53. section without header

Well, there is no <header>, but the <h2>-heading leaves pretty clear which part in this section is the header.

line 63. Div with all (non-related) news items

<article> or <aside> might be better.

line 64. header with h2

Discussed already.

line 65. Hmm, div or section? Or remove this div and only use the article-tag

Exactly! Remove the <div>.

line 105. Footer :-)

Very reasonable.

This is a follow up to my original question to help out others with the same problem. If you need to filter by an attribute, rather than manually looking up the id you can use the following code to retrieve all the id, value pairs for an attribute. The data is returned as an array with the attribute name as the key.

function getAttributeOptions($attributeName) {
    $product = Mage::getModel('catalog/product');
    $collection = Mage::getResourceModel('eav/entity_attribute_collection')
              ->setEntityTypeFilter($product->getResource()->getTypeId())
              ->addFieldToFilter('attribute_code', $attributeName);

    $_attribute = $collection->getFirstItem()->setEntity($product->getResource());
    $attribute_options  = $_attribute->getSource()->getAllOptions(false);
    foreach($attribute_options as $val) {
        $attrList[$val['label']] = $val['value'];
    }   

    return $attrList;
}

Here is a function you can use to get products by their attribute set id. Retrieved using the previous function.

function getProductsByAttributeSetId($attributeSetId) {
   $products = Mage::getModel('catalog/product')->getCollection();
   $products->addAttributeToFilter('attribute_set_id',$attributeSetId);

   $products->addAttributeToSelect('*');

   $products->load();
   foreach($products as $val) {
     $productsArray[] = $val->getData();
  }

  return $productsArray;
}

Try this,

ArrayList<Double> numb= new ArrayList<Double>(Arrays.asList(1.38, 2.56, 4.3));

An alternative, you can also use fopen

$params = array('http' => array(
    'method' => 'POST',
    'content' => 'toto=1&tata=2'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if (!$fp)
{
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if ($response === false) 
{
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

@Alexander Thanks for solution

Below is code exactly what you looking for

Below is the Screenshot

If it´s in the global scope it´s better to use:

function foo()
{
    alert('foo');
}

var a = 'foo';
window[a]();

than eval(). Because eval() is evaaaaaal.

Exactly like Nosredna said 40 seconds before me that is >.<

self is inevitable.

There was just a question should self be implicit or explicit. Guido van Rossum resolved this question saying self has to stay.

So where the self live?

If we would just stick to functional programming we would not need self. Once we enter the Python OOP we find self there.

Here is the typical use case class C with the method m1

class C:
    def m1(self, arg):
        print(self, ' inside')
        pass

ci =C()
print(ci, ' outside')
ci.m1(None)
print(hex(id(ci))) # hex memory address

This program will output:

<__main__.C object at 0x000002B9D79C6CC0>  outside
<__main__.C object at 0x000002B9D79C6CC0>  inside
0x2b9d79c6cc0

So self holds the memory address of the class instance. The purpose of self would be to hold the reference for instance methods and for us to have explicit access to that reference.

_{Note there are three different types of class methods:}

• _{static methods (read: functions),}
• _{class methods,}
• _{instance methods (mentioned).}

Visual Studio 2012 (with ASP.NET and Web Tools 2012.2 RC installed) supports this natively.

Visual Studio 2013 onwards have this built-in.

A lot of these answers are referring to the Nuget packages and/or cleaning and reloading your project.

If you have WCF service references and invalid endpoints, you can also get this error message. Make sure your endpoints are correct and update the service configuration with the correct endpoint in the .config and when you configure the service reference from the GUI.

jRadioOne = new javax.swing.JRadioButton();
jRadioTwo = new javax.swing.JRadioButton();
jRadioThree = new javax.swing.JRadioButton();

... then for every button:

buttonGroup1.add(jRadioOne);
jRadioOne.setText("One");
jRadioOne.setActionCommand(ONE);
jRadioOne.addActionListener(radioButtonActionListener);

...listener

ActionListener radioButtonActionListener = new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                radioButtonActionPerformed(evt);
            }
        };

...do whatever you need as response to event

protected void radioButtonActionPerformed(ActionEvent evt) {            
       System.out.println(evt.getActionCommand());
    }

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Much easier aproach. Consider a task:

provision:
        ansible-playbook -vvvv \
        -i .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory \
        --private-key=.vagrant/machines/default/virtualbox/private_key \
        --start-at-task="$(AT)" \
        -u vagrant playbook.yml

Now when I want to call it I just run something like:

AT="build assets" make provision

or just:

make provision in this case AT is an empty string

If you want to just check if they are identical or not, a == b should give you true / false with ordering taken into account.

In case you want to compare elements, you can use numpy for comparison

c = (numpy.array(a) == numpy.array(b))

Here, c will contain an array with 3 elements all of which are true (for your example). In the event elements of a and b don't match, then the corresponding elements in c will be false.

I was also getting the same problem, but i uninstalled all updates of java and now it is working very fine....

You can observe the relation between features either by drawing a heat map from seaborn or scatter matrix from pandas.

Scatter Matrix:

pd.scatter_matrix(dataframe, alpha = 0.3, figsize = (14,8), diagonal = 'kde');

If you want to visualize each feature's skewness as well - use seaborn pairplots.

sns.pairplot(dataframe)

Sns Heatmap:

import seaborn as sns

f, ax = pl.subplots(figsize=(10, 8))
corr = dataframe.corr()
sns.heatmap(corr, mask=np.zeros_like(corr, dtype=np.bool), cmap=sns.diverging_palette(220, 10, as_cmap=True),
            square=True, ax=ax)

The output will be a correlation map of the features. i.e. see the below example.

The correlation between grocery and detergents is high. Similarly:

1. Grocery and Detergents.

1. Milk and Grocery
2. Milk and Detergents_Paper

1. Milk and Deli
2. Frozen and Fresh.
3. Frozen and Deli.

From Pairplots: You can observe same set of relations from pairplots or scatter matrix. But from these we can say that whether the data is normally distributed or not.

Note: The above is same graph taken from the data, which is used to draw heatmap.

Print the Upper and Lower case alphabets in python using a built-in range function

def upperCaseAlphabets():
    print("Upper Case Alphabets")
    for i in range(65, 91):
        print(chr(i), end=" ")
    print()

def lowerCaseAlphabets():
    print("Lower Case Alphabets")
    for i in range(97, 123):
        print(chr(i), end=" ")

upperCaseAlphabets();
lowerCaseAlphabets();

You can do

Component depCountry = lstComp
                       .Select(x => x.ComponentValue("Dep"))
                       .FirstOrDefault();

Alternatively if you are wanting this for the entire dictionary of values, you can even tie it back to the key

var newDictionary = dic.Select(x => new 
            {
               Key = x.Key,
               Value = x.Value.Select( y => 
                      {
                          depCountry = y.ComponentValue("Dep")
                      }).FirstOrDefault()
             }
             .Where(x => x.Value != null)
             .ToDictionary(x => x.Key, x => x.Value());

This will give you a new dictionary. You can access the values

var myTest = newDictionary[key1].depCountry     

style.format is vectorized, so we can simply apply it to the entire df (or just its numerical columns):

df[num_cols].style.format('{:,.3f}')

You can also use python chardet library

# install the chardet library
!pip install chardet

# import the chardet library
import chardet 

# use the detect method to find the encoding
# 'rb' means read in the file as binary
with open("test.csv", 'rb') as file:
    print(chardet.detect(file.read()))

As I was researching this I thought it would be nice to modify the BETWEEN solution to show an example for a particular non-static/string date, but rather a variable date, or today's such as CURRENT_DATE(). This WILL use the index on the log_timestamp column.

SELECT *
FROM some_table
WHERE
    log_timestamp
    BETWEEN 
        timestamp(CURRENT_DATE()) 
    AND # Adds 23.9999999 HRS of seconds to the current date
        timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL '86399.999999' SECOND_MICROSECOND));

I did the seconds/microseconds to avoid the 12AM case on the next day. However, you could also do `INTERVAL '1 DAY' via comparison operators for a more reader-friendly non-BETWEEN approach:

SELECT *
FROM some_table
WHERE
    log_timestamp >= timestamp(CURRENT_DATE()) AND
    log_timestamp < timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL 1 DAY));

Both of these approaches will use the index and should perform MUCH faster. Both seem to be equally as fast.

Here is an example of how to overwrite Logger configuration from the code. Does not require external configuration file ..

FileLoggerTest.java:

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.LogManager;
import java.util.logging.Logger;

public class FileLoggerTest {

    public static void main(String[] args) {

        try {
            String h = MyLogHandler.class.getCanonicalName();
            StringBuilder sb = new StringBuilder();
            sb.append(".level=ALL\n");
            sb.append("handlers=").append(h).append('\n');
            LogManager.getLogManager().readConfiguration(new ByteArrayInputStream(sb.toString().getBytes("UTF-8")));
        } catch (IOException | SecurityException ex) {
            // Do something about it
        }

        Logger.getGlobal().severe("Global SEVERE log entry");
        Logger.getLogger(FileLoggerTest.class.getName()).log(Level.SEVERE, "This is a SEVERE log entry");
        Logger.getLogger("SomeName").log(Level.WARNING, "This is a WARNING log entry");
        Logger.getLogger("AnotherName").log(Level.INFO, "This is an INFO log entry");
        Logger.getLogger("SameName").log(Level.CONFIG, "This is an CONFIG log entry");
        Logger.getLogger("SameName").log(Level.FINE, "This is an FINE log entry");
        Logger.getLogger("SameName").log(Level.FINEST, "This is an FINEST log entry");
        Logger.getLogger("SameName").log(Level.FINER, "This is an FINER log entry");
        Logger.getLogger("SameName").log(Level.ALL, "This is an ALL log entry");

    }
}

MyLogHandler.java

import java.io.IOException;
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.LogRecord;
import java.util.logging.SimpleFormatter;

public final class MyLogHandler extends FileHandler {

    public MyLogHandler() throws IOException, SecurityException {
        super("/tmp/path-to-log.log");
        setFormatter(new SimpleFormatter());
        setLevel(Level.ALL);
    }

    @Override
    public void publish(LogRecord record) {
        System.out.println("Some additional logic");
        super.publish(record);
    }

}

bin/kafka-topics.sh –delete –zookeeper localhost:2181 –topic <topic-name>

i'd suggest shorter and faster approach:

printf("%.2f", ((signed long)(fVal * 100) * 0.01f));

this way you won't overflow int, plus multiplication by 100 shouldn't influence the significand/mantissa itself, because the only thing that really is changing is exponent.

Try using:

string ap = c.Request["AP"];

That reads from the cookies, form, query string or server variables.

Alternatively:

string ap = c.Request.Form["AP"];

to just read from the form's data.

try this

$start_date = date_create($_POST['start_date']);
$start_date = date_format($start_date,"Y-m-d H:i:s");

I just had this problem and I first switched to another directory and then switched back and the problem was fixed.

You have 2 options

1) Use javascript to confirm deletion (use onsubmit event handler), however if the client has JS disabled, you're in trouble.

2) Use PHP to echo out a confirmation message, along with the contents of the form (hidden if you like) as well as a submit button called "confirmation", in PHP check if $_POST["confirmation"] is set.

After trying to get this to work for too many hours, I finally found this: https://github.com/vierno/django-xhtml2pdf

It's a fork of https://github.com/chrisglass/django-xhtml2pdf that provides a mixin for a generic class-based view. I used it like this:

    # views.py
    from django_xhtml2pdf.views import PdfMixin
    class GroupPDFGenerate(PdfMixin, DetailView):
        model = PeerGroupSignIn
        template_name = 'groups/pdf.html'

    # templates/groups/pdf.html
    <html>
    <style>
    @page { your xhtml2pdf pisa PDF parameters }
    </style>
    </head>
    <body>
        <div id="header_content"> (this is defined in the style section)
            <h1>{{ peergroupsignin.this_group_title }}</h1>
            ...

Use the model name you defined in your view in all lowercase when populating the template fields. Because its a GCBV, you can just call it as '.as_view' in your urls.py:

    # urls.py (using url namespaces defined in the main urls.py file)
    url(
        regex=r"^(?P<pk>\d+)/generate_pdf/$",
        view=views.GroupPDFGenerate.as_view(),
        name="generate_pdf",
       ),

None of the answers worked for me. But inspired in BarryPye's answer I found out it works when using relative paths!

# Contents from the '/media/user/README_1.md' markdown file:

Read more [here](./README_2.md) # It works!
Read more [here](file:///media/user/README_2.md) # Doesn't work
Read more [here](/media/user/README_2.md) # Doesn't work

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

Convert by Number Class:-

Eg:

var n = Number("103");
console.log(n+1)

Output: 104

Note:- Number is class. When we pass string, then constructor of Number class will convert it.

Sometimes implicit wait seems to get overridden and wait time is cut short. [@eugene.polschikov] had good documentation on the whys. I have found in my testing and coding with Selenium 2 that implicit waits are good but occasionally you have to wait explicitly.

It is better to avoid directly calling for a thread to sleep, but sometimes there isn't a good way around it. However, there are other Selenium provided wait options that help. waitForPageToLoad and waitForFrameToLoad have proved especially useful.

you can use this for example

$array = json_decode($string,true)

but validate the Json before. You can validate from http://jsonviewer.stack.hu/

You can use bash arrays

$ str_array=("continuation"
             "lines")

then

$ echo "${str_array[*]}"
continuation lines

there is an extra space, because (after bash manual):

If the word is double-quoted, ${name[*]} expands to a single word with the value of each array member separated by the first character of the IFS variable

So set IFS='' to get rid of extra space

$ IFS=''
$ echo "${str_array[*]}"
continuationlines

TCP establishes a connection before the actual data transmission takes place, UDP does not. In this way, UDP can provide faster delivery. Applications like DNS, time server access, therefore, use UDP.

Unlike UDP, TCP uses congestion control. It responses to the network load. Unlike UDP, it slows down when network congestion is imminent. So, applications like multimedia preferring constant throughput might go for UDP.

Besides, UDP is unreliable, it doesn't react on packet losses. So loss sensitive applications like multimedia transmission prefer UDP. However, TCP is a reliable protocol, so, applications that require reliability such as web transfer, email, file download prefer TCP.

Besides, in today's internet UDP is not as welcoming as TCP due to middle boxes. Some applications like skype fall down to TCP when UDP connection is assumed to be blocked.

Another method that people should consider using is Shared Workers. I know it's a cutting edge concept, but you can create a relay on a Shared Worker that is MUCH faster than localstorage, and doesn't require a relationship between the parent/child window, as long as you're on the same origin.

See my answer here for some discussion I made about this.

As mentioned above, the following link gives you the specific country code to allow Java to localize the number. Every country has its own style.

In the link above you will find the country code which should be placed in here:

...(new Locale(<COUNTRY CODE HERE>));

Switzerland for example formats the numbers as follows:

1000.00 --> 1'000.00

country code

To achieve this, following codes works for me:

NumberFormat nf = NumberFormat.getNumberInstance(new Locale("de","CH"));
nf.setMaximumFractionDigits(2);
DecimalFormat df = (DecimalFormat)nf;
System.out.println(df.format(1000.00));

Result is as expected:

1'000.00

When this problem comes up with multiprocessing a simple solution is to switch from Pool to ThreadPool. This can be done with no change of code other than the import-

from multiprocessing.pool import ThreadPool as Pool

This works because ThreadPool shares memory with the main thread, rather than creating a new process- this means that pickling is not required.

The downside to this method is that python isn't the greatest language with handling threads- it uses something called the Global Interpreter Lock to stay thread safe, which can slow down some use cases here. However, if you're primarily interacting with other systems (running HTTP commands, talking with a database, writing to filesystems) then your code is likely not bound by CPU and won't take much of a hit. In fact I've found when writing HTTP/HTTPS benchmarks that the threaded model used here has less overhead and delays, as the overhead from creating new processes is much higher than the overhead for creating new threads.

So if you're processing a ton of stuff in python userspace this might not be the best method.

in Mac Remove Java Version using this 3 Commands

java -version

sudo rm -rf /Library/Java/*

sudo rm -rf /Library/PreferencePanes/Java*

sudo rm -rf /Library/Internet\ Plug-Ins/Java*

Run

java -version

//See java was successfully uninstalled.

java -version sudo rm -rf /Library/Java/* sudo rm -rf /Library/PreferencePanes/Java* sudo rm -rf /Library/Internet\ Plug-Ins/Java*

In your first example, you are correct. The batch will hit the commit transaction, regardless of whether the try block fires.

In your second example, I agree with other commenters. Using the success flag is unnecessary.

I consider the following approach to be, essentially, a light weight best practice approach.

If you want to see how it handles an exception, change the value on the second insert from 255 to 256.

CREATE TABLE #TEMP ( ID TINYINT NOT NULL );
INSERT  INTO #TEMP( ID ) VALUES  ( 1 )

BEGIN TRY
    BEGIN TRANSACTION

    INSERT  INTO #TEMP( ID ) VALUES  ( 2 )
    INSERT  INTO #TEMP( ID ) VALUES  ( 255 )

    COMMIT TRANSACTION
END TRY
BEGIN CATCH
    DECLARE 
        @ErrorMessage NVARCHAR(4000),
        @ErrorSeverity INT,
        @ErrorState INT;
    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();
    RAISERROR (
        @ErrorMessage,
        @ErrorSeverity,
        @ErrorState    
        );
    ROLLBACK TRANSACTION
END CATCH

SET NOCOUNT ON

SELECT ID
FROM #TEMP

DROP TABLE #TEMP

here is my example:

if(userAnswer==="Yes"||"yes"||"YeS"){
 console.log("Too Bad!");   
}

This says that if the answer is Yes yes or YeS than the same thing will happen

sudo apt-get update   
sudo apt purge python2.7-minimal

I ended up keeping Link and adding the reload to the Link's onClick event with a timeout like this:

function refreshPage() {
    setTimeout(()=>{
        window.location.reload(false);
    }, 500);
    console.log('page to reload')
}

<Link to={{pathname:"/"}} onClick={refreshPage}>Home</Link>

without the timeout, the refresh function would run first

string  myMessage="helloworld";
int len;
int slength = (int)myMessage.length() + 1;
len = MultiByteToWideChar(CP_ACP, 0, myMessage.c_str(), slength, 0, 0); 
wchar_t* buf = new wchar_t[len];
MultiByteToWideChar(CP_ACP, 0, myMessage.c_str(), slength, buf, len);
std::wstring r(buf);
 std::wstring stemp = r.C_str();
LPCWSTR result = stemp.c_str();

How would one specify multiple algorithms? I ask because git just updated on my work laptop, (Windows 10, using the official Git for Windows build,) and I got this error when I tried to push a project branch to my Azure DevOps remote. I tried to push --set-upstream and got this:

Unable to negotiate with 20.44.80.98 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

So how would one implement the suggestions above allowing for both of those? (As a quick get-it-done, I used @golvok's solution with group14 and it worked, but I really don't know if 1 or 14 is better, etc.)

After investigating lots of alternatives, I have come across another approach, suitable for the API 2.0 version.

(VB.NET is my favorite, sooo...)

Public Async Function APIPut_Response(ID as Integer, MyWidget as Widget) as Task(Of HttpResponseMessage)
    Dim DesiredContent as HttpContent = New StringContent(JsonConvert.SerializeObject(MyWidget))
    Return Await APIClient.PutAsync(String.Format("api/widget/{0}", ID), DesiredContent)
End Function

Good luck! For me this worked out (in the end!).
