You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

My "API Server" is an PHP Application so to solve this problem I found the below solution to work:

Place the lines in index.php

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token');

This bug is still not fixed in 23.1.1, but a common workaround would be to catch the exception.

I ran into a similar issue and just figured it out. I hard-coded a few examples for a test case but didn't ensure they each returned a unique ID and that caused the below crash for me. Fixing the IDs resolved the issue, hope this helps someone else!

Someone posted this link to the MDN in a comment, and I think it was very helpful. It describes things like ErrorTypes very thoroughly.

EvalError --- Creates an instance representing an error that occurs regarding the global function eval().

InternalError --- Creates an instance representing an error that occurs when an internal error in the JavaScript engine is thrown. E.g. "too much recursion".

RangeError --- Creates an instance representing an error that occurs when a numeric variable or parameter is outside of its valid range.

ReferenceError --- Creates an instance representing an error that occurs when de-referencing an invalid reference.

SyntaxError --- Creates an instance representing a syntax error that occurs while parsing code in eval().

TypeError --- Creates an instance representing an error that occurs when a variable or parameter is not of a valid type.

URIError --- Creates an instance representing an error that occurs when encodeURI() or decodeURI() are passed invalid parameters.

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

Similarly using Bash regexp. Shall be able to snatch any key/value pair.

key="Body"
re="\"($key)\": \"([^\"]*)\""

while read -r l; do
    if [[ $l =~ $re ]]; then
        name="${BASH_REMATCH[1]}"
        value="${BASH_REMATCH[2]}"
        echo "$name=$value"
    else
        echo "No match"
    fi
done

Regular expression can be tuned to match multiple spaces/tabs or newline(s). Wouldn't work if value has embedded ". This is an illustration. Better to use some "industrial" parser :)

catch (Exception ex) { ... }

WILL catch RuntimeException.

Whatever you put in catch block will be caught as well as the subclasses of it.

Use if(index.length() < 0) for Integer

or

Use if(index.equals(null) for String

This is Very Good Example of minus Length of an array in java, i am giving here both examples

 public static int linearSearchArray(){

   int[] arrayOFInt = {1,7,5,55,89,1,214,78,2,0,8,2,3,4,7};
   int key = 7;
   int i = 0;
   int count = 0;
   for ( i = 0; i< arrayOFInt.length; i++){
        if ( arrayOFInt[i]  == key ){
         System.out.println("Key Found in arrayOFInt = " + arrayOFInt[i] );
         count ++;
        }
   }

   System.out.println("this Element found the ("+ count +") number of Times");
return i;  
}

this above i < arrayOFInt.length; not need to minus one by length of array; but if you i <= arrayOFInt.length -1; is necessary other wise arrayOutOfIndexException Occur, hope this will help you.

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

Did the error also report that it was missing an application name? I had this issue until I created a project name (e.g. "Project X") in the project settings dialog.

Better solution for your Stack implementation

import java.util.List;
import java.util.ArrayList;
public class IntegerStack 

{

    private List<Integer> stack;

    public IntegerStack(int SIZE) 
    {
        stack = new ArrayList<Integer>(SIZE);
    }

    public void push(int i) 
    {

       stack.add(0,i);
     }

     public int pop() 
     { 
        if(!stack.isEmpty()){
           int i= stack.get(0);
           stack.remove(0);
           return i;
        } else{
           return -1;// Or any invalid value
        }
     }

     public int peek()
     {
        if(!stack.isEmpty()){
           return stack.get(0);
        } else{
           return -1;// Or any invalid value
        }
     }


     public boolean isEmpty() 
     {
       stack.isEmpty();
     }

 }

If you have to use Array... Here are problems in your code and possible solutions

import java.util.Arrays;
public class IntegerStack 
{

    private int stack [];
    private int top; 

    public IntegerStack(int SIZE) 
   {
    stack = new int [SIZE];
    top = -1; // top should be 0. If you keep it as -1, problems will arise when SIZE is passed as 0. 
    // In your push method -1==0 will be false and your code will try to add the invalid element to Stack .. 
     /**Solution top=0; */
    }

public void push(int i) 
{
    if (top == stack.length)
    {
        extendStack();
    }

       stack[top]= i;
        top++;

}

public int pop() 
{
    top --; // here you are reducing the top before giving the Object back 
   /*Solution 
      if(!isEmpty()){
      int value = stack[top];
       top --;
     return value; 
    } else{
      return -1;// OR invalid value
    }
   */
    return stack[top];
}

public int peek()
{
    return stack[top]; // Problem when stack is empty or size is 0
    /*Solution 
       if(!isEmpty()){
         return stack[top];
       }else{
         return -1;// Or any invalid value
       }
    */


}


public boolean isEmpty() 
{
    if ( top == -1); // problem... we changed top to 0 above so here it need to check if its 0 and there should be no semicolon after the if statement
   /* Solution if(top==0) */
    {
        return true;
    }
}

private void extendStack()
{

    int [] copy = Arrays.copyOf(stack, stack.length); // The second parameter in Arrays.copyOf has no changes, so there will be no change in array length.
  /*Solution  
    stack=Arrays.copyOf(stack, stack.length+1); 
   */
     }

     }

The right way to iterate on a list inside list is:

//iterate on the general list
for(int i = 0 ; i < collection.size() ; i++) {
    ArrayList<String> currentList = collection.get(i);
    //now iterate on the current list
    for (int j = 0; j < currentList.size(); j++) {
        String s = currentList.get(1);
    }
}

You can use a regular expression to delete white spaces , try that snippet:

Scanner scan = new Scanner(System.in);
    System.out.println(scan.nextLine().replaceAll(" ", ""));

My solution is based on @Martijn Pieters' comment:

register_namespace only influences serialisation, not search.

So the trick here is to use different dictionaries for serialization and for searching.

namespaces = {
    '': 'http://www.example.com/default-schema',
    'spec': 'http://www.example.com/specialized-schema',
}

Now, register all namespaces for parsing and writing:

for name, value in namespaces.iteritems():
    ET.register_namespace(name, value)

For searching (find(), findall(), iterfind()) we need a non-empty prefix. Pass these functions a modified dictionary (here I modify the original dictionary, but this must be made only after the namespaces are registered).

self.namespaces['default'] = self.namespaces['']

Now, the functions from the find() family can be used with the default prefix:

print root.find('default:myelem', namespaces)

but

tree.write(destination)

does not use any prefixes for elements in the default namespace.

I believe you should escape the dot. Try:

String filename = "D:/some folder/001.docx";
String extensionRemoved = filename.split("\\.")[0];

Otherwise dot is interpreted as any character in regular expressions.

Starting from Java 10:

List<E> oldList = List.of();
List<E> newList = List.copyOf(oldList);

List.copyOf() returns an unmodifiable List containing the elements of the given Collection.

The given Collection must not be null, and it must not contain any null elements.

Also, if you want to create a deep copy of a List, you can find many good answers here.

Some online API's work pretty well: ocr.space and Google Cloud Vision. Both of these are free, as long as you do less than 1000 OCR's per month. You can drag & drop an image to do a quick manual test to see how they perform for your images.

I find OCR.space easier to use (no messing around with nuget libraries), but, for my purpose, Google Cloud Vision provided slightly better results than OCR.space.

Google Cloud Vision example:

GoogleCredential cred = GoogleCredential.FromJson(json);
Channel channel = new Channel(ImageAnnotatorClient.DefaultEndpoint.Host, ImageAnnotatorClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
ImageAnnotatorClient client = ImageAnnotatorClient.Create(channel);
Image image = Image.FromStream(stream);

EntityAnnotation googleOcrText = client.DetectText(image).First();
Console.Write(googleOcrText.Description);

OCR.space example:

string uri = $"https://api.ocr.space/parse/imageurl?apikey=helloworld&url={imageUri}";
string responseString = WebUtilities.DoGetRequest(uri);
OcrSpaceResult result = JsonConvert.DeserializeObject<OcrSpaceResult>(responseString);
if ((!result.IsErroredOnProcessing) && !String.IsNullOrEmpty(result.ParsedResults[0].ParsedText))
  return result.ParsedResults[0].ParsedText;

I don't want to give out the full code. So I want to give you the challenge and have fun with it. I encourage you to make the code simpler and with only 1 loop.

Basically, my idea is to pair up the characters comparison, side by side. For example, compare char 1 with char 2, char 2 with char 3, and so on. When char N not the same with char (N+1) then reset the character count. You can do this in one loop only! While processing this, form a new string. Don't use the same string as your input. That's confusing.

Remember, making things simple counts. Life for developers is hard enough looking at complex code.

Have fun!

Tommy "I should be a Teacher" Kwee

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

I draw your attention to the ArrayList.add documentation, which says it throws IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size())

Check the size() of your list before you call list.add(1, object1)

You need two backslashes before the dot, one to escape the slash so it gets through, and the other to escape the dot so it becomes literal. Forward slashes and asterisk are treated literal.

str=xpath.replaceAll("\\.", "/*/");          //replaces a literal . with /*/

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#replaceAll(java.lang.String,%20java.lang.String)

List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
    if(s.equals(value)){
        //do something
    }
}

or

for (int i = 0; i < arrayList.size(); i++) {
    if(arrayList.get(i).equals(value)){
        //do something
    }
}

But be carefull ArrayList can hold null values. So comparation should be

value.equals(arrayList.get(i))

when you are sure that value is not null or you should check if given element is null.

The exception is thrown if

InvocationTargetException - if the underlying method throws an exception.

So if the method, that has been invoked with reflection API, throws an exception (runtime exception for example), the reflection API will wrap the exception into an InvocationTargetException.

// apparently this is broken. Whoops for me!
java.util.Collections.fill(list,new Integer(0));

// this is better
Integer[] data = new Integer[60];
Arrays.fill(data,new Integer(0));
List<Integer> list = Arrays.asList(data);

So much for this simple question, but I just wanted to highlight a new feature in Java which will avoid all confusions around indexing in arrays even for beginners. Java-8 has abstracted the task of iterating for you.

int[] array = new int[5];

//If you need just the items
Arrays.stream(array).forEach(item -> { println(item); });

//If you need the index as well
IntStream.range(0, array.length).forEach(index -> { println(array[index]); })

What's the benefit? Well, one thing is the readability like English. Second, you need not worry about the ArrayIndexOutOfBoundsException

This worked for me. Hope it helps someone. :)

SimpleAdapter adapter = (SimpleAdapter) getListAdapter();
this.resultsList.remove((int) info.id);
adapter.notifyDataSetChanged();

In Java 8, it's now as simple as:

movieItems.sort(Comparator.comparing(Movie::getDate));

Have you tried escaping the dot? like this:

I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:

HKEY_LOCAL_MACHINE\SOFTWARE\Python

to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python

Worked for me

solution found at the address below so credits should go there: http://effbot.slinkset.com/items/Adding_Python_Information_to_the_Windows_Registry

Use the substring method, as follows:

int n = 8;
String s = "Hello, World!";
System.out.println(s.substring(0,n);

If n is greater than the length of the string, this will throw an exception, as one commenter has pointed out. one simple solution is to wrap all this in the condition if(s.length()<n) in your else clause, you can choose whether you just want to print/return the whole String or handle it another way.

You really need to check if the string's length is greater to or equal to 38.

You can use a function like this. Complete and modify it to your need :

/**
     * Encode URL (except :, /, ?, &, =, ... characters)
     * @param url to encode
     * @param encodingCharset url encoding charset
     * @return encoded URL
     * @throws UnsupportedEncodingException
     */
    public static String encodeUrl (String url, String encodingCharset) throws UnsupportedEncodingException{
            return new URLCodec().encode(url, encodingCharset).replace("%3A", ":").replace("%2F", "/").replace("%3F", "?").replace("%3D", "=").replace("%26", "&");
    }

Example of use :

String urlToEncode = ""http://www.growup.com/folder/intérieur-à_vendre?o=4";
Utils.encodeUrl (urlToEncode , "UTF-8")

The result is : http://www.growup.com/folder/int%C3%A9rieur-%C3%A0_vendre?o=4

Depending on why you are doing this, using a std::set might be a better idea than std::vector.

It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.

This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.

Try something like:

import pylab as p
p.plot(x,y)

When you directly run the rake task or execute any binary file of a gem, there is no guarantee that the command will behave as expected. Because it might happen that you already have the same gem installed on your system which have a version say 1.0 but in your project you have higher version say 2.0. In this case you can not predict which one will be used.

To enforce the desired gem version you take the help of bundle exec command which would execute the binary in context of current bundle. That means when you use bundle exec, bundler checks the gem version configured for the current project and use that to perform the task.

I have also written a post about it which also shows how we can avoid using it using bin stubs.

I have used this with success in Chrome, Firefox, and Safari. Haven't been able to test it in IE yet.

if($(document).scrollTop() !=0){
    $('html, body').animate({ scrollTop: 0 }, 'fast');
}

The reason for the "if" statement is to check if the user is all ready at the top of the site. If so, don't do the animation. That way we don't have to worry so much about screen resolution.

The reason I use $(document).scrollTop instead of ie. $('html,body') is cause Chrome always return 0 for some reason.

I suggest that you start from a question in StackOverflow that discusses the advantages of stateless programming. This is more in the context of functional programming, but what you will read also applies in other programming paradigms.

Stateless programming is related to the mathematical notion of a function, which when called with the same arguments, always return the same results. This is a key concept of the functional programming paradigm and I expect that you will be able to find many relevant articles in that area.

Another area that you could research in order to gain more understanding is RESTful web services. These are by design "stateless", in contrast to other web technologies that try to somehow keep state. (In fact what you say that ASP.NET is stateless isn't correct - ASP.NET tries hard to keep state using ViewState and are definitely to be characterized as stateful. ASP.NET MVC on the other hand is a stateless technology). There are many places that discuss "statelessness" of RESTful web services (like this blog spot), but you could again start from an SO question.

You will have an if-check no matter how efficient you try to optimize this not-so-intensive computation :) You can subtract the upper bound from the number and if it's positive you know you are out of range. You can perhaps perform some boolean bit-shift logic to figure it out and you can even use Fermat's theorem if you want (kidding :) But the point is "why" do you need to optimize this comparison? What's the purpose?

Quick answer on OSX, set your environment variables.

>export PGPORT=5432

Or whatever you need.

(I'm going to ignore handling input, its just a distraction.)

The easy way is to sort it.

#include <stdlib.h>
#include <stdio.h>

int cmp_int( const void *a, const void *b ) {
    return *(int*)a - *(int*)b;
}

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    const int n = sizeof(a) / sizeof(a[0]);

    qsort(a, n, sizeof(a[0]), cmp_int);
    printf("%d %d\n", a[n-1], a[n-2]);
}

But that isn't the most efficient because it's O(n log n), meaning as the array gets bigger the number of comparisons gets bigger faster. Not too fast, slower than exponential, but we can do better.

We can do it in O(n) or "linear time" meaning as the array gets bigger the number of comparisons grows at the same rate.

Loop through the array tracking the max, that's the usual way to find the max. When you find a new max, the old max becomes the 2nd highest number.

Instead of having a second loop to find the 2nd highest number, throw in a special case for running into the 2nd highest number.

#include <stdio.h>
#include <limits.h>

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    // This trick to get the size of an array only works on stack allocated arrays.
    const int n = sizeof(a) / sizeof(a[0]);

    // Initialize them to the smallest possible integer.
    // This avoids having to special case the first elements.
    int max = INT_MIN;
    int second_max = INT_MIN;

    for( int i = 0; i < n; i++ ) {
        // Is it the max?
        if( a[i] > max ) {
            // Make the old max the new 2nd max.
            second_max = max;
            // This is the new max.
            max = a[i];
        }
        // It's not the max, is it the 2nd max?
        else if( a[i] > second_max ) {
            second_max = a[i];
        }
    }

    printf("max: %d, second_max: %d\n", max, second_max);
}

There might be a more elegant way to do it, but that will do, at most, 2n comparisons. At best it will do n.

Note that there's an open question of what to do with { 1, 2, 3, 3 }. Should that return 3, 3 or 2, 3? I'll leave that to you to decide and adjust accordingly.

Using pretty much any modern browser you need to learn the Network tab. See this SO post about How to debug AJAX calls.

Add the hidden titleLabel to the parameter is the best solution.

I generated a array arrUrl which store the NSURL of the mov files in my phone album by enumerate assets block.

After that, I grab on Frame, lets say, get the frame at 3:00 second in the movie file, and generated the image file from the frame.

Next, loop over the arrUrl, and use program generate the button with image in the button, append the button to subview of the self.view.

Because I have to pass the movie Url to playMovie function, I have to assign the button.titleLabel.text with one movie url. and the the button events function, retrieve the url from the buttontitleLable.txt.

-(void)listVideos

{
   for(index=0;index<[self.arrUrl count];index++{
      UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
      imageButton.frame = CGRectMake(20,50+60*index,50,50);

      NSURL *dUrl = [self.arrUrl objectAtIndex:index];

      [imageButton setImage:[[UIImage allow] initWithCGImage:*[self getFrameFromeVideo:dUrl]] forState:UIControlStateNormal];
      [imageButton addTarget:self action:@selector(playMovie:) forControlEvents:UIControlEventTouchUpInside];
      imageButton.titleLabel.text = [NSString strinfWithFormat:@"%@",dUrl];
      imageButton.titleLabel.hidden = YES;

      [self.view addSubView:imageButton];
   }
}

-(void)playMovie:(id) sender{
   UIButton *btn = (UIButton *)sender;
   NSURL *movUrl = [NSURL URLWithString:btn.titleLabel.text];
   moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movUrl];
   [self presentMoviePlayerViewControllerAnimated:moviePlayer];
}

-(CGIImageRef *)getFrameFromVideo:(NSURL *)mUrl{
   AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:mUrl option:nil];
   AVAssetImageGenerator *generator = [[AVAssetImageGenerator alloc] initWithAsset:asset];
   generator.appliesPreferredTrackTransform = YES;
   NSError *error =nil;
   CMTime = CMTimeMake(3,1);
   CGImageRef imageRef = [generator copyCGImageAtTime:time actualTime:nil error:&error];
   if(error !=nil) {
      NSLog(@"%@",sekf,error);
   }

   return @imageRef;
}

Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.

I was having a lot of problems to get this working, every single solution I found didn't seem to work.

I realized that I had to set the div display to flex, so basically this is my CSS:

div{
display: flex;
}

div img{ 
max-height: 100%;
max-width: 100%;
}

You can give variable names as project files. For instance in you plugin configuration give only one tag as below:-

<projectFile>${projectName}</projectFile>

Then on command line you can pass the project name as parameter:-

mvn [your-command] -DprojectName=[name of project]

int main()
{
  int array[11];
  printf("Write down your ID number!\n");
  for(int i=0;i<id_length;i++)
  scanf("%d", &array[i]);
  if (array[0]==1)
  {
    printf("\nThis person is a male.");
  }
  else if (array[0]==2)
  {
    printf("\nThis person is a female.");
  }
  return 0;
}

My way is much more simpler. You can tweak with the return strings as you want

    public static string TimeLeft(DateTime utcDate)
    {
        TimeSpan timeLeft = DateTime.UtcNow - utcDate;
        string timeLeftString = "";
        if (timeLeft.Days > 0)
        {
            timeLeftString += timeLeft.Days == 1 ? timeLeft.Days + " day" : timeLeft.Days + " days";
        }
        else if (timeLeft.Hours > 0)
        {
            timeLeftString += timeLeft.Hours == 1 ? timeLeft.Hours + " hour" : timeLeft.Hours + " hours";
        }
        else
        {
            timeLeftString += timeLeft.Minutes == 1 ? timeLeft.Minutes+" minute" : timeLeft.Minutes + " minutes";
        }
        return timeLeftString;
    }

You may simply use MultipartHttpServletRequest

Example:

 @RequestMapping(value={"/upload"}, method = RequestMethod.POST,produces = "text/html; charset=utf-8")
 @ResponseBody
 public String upload(MultipartHttpServletRequest request /*@RequestBody MultipartFile file*/){
    String responseMessage = "OK";
    MultipartFile file = request.getFile("file");
    String param = request.getParameter("param");
    try {
        System.out.println(file.getOriginalFilename());
        System.out.println("some param = "+param);
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(file.getInputStream(), StandardCharsets.UTF_8));
        // read file
    }
    catch(Exception ex){
        ex.printStackTrace();
        responseMessage = "fail";
    }
     return responseMessage;
}

Where parameters names in request.getParameter() must be same with corresponding frontend names.

Note, that file extracted via getFile() while other additional parameters extracted via getParameter()

There is no better way but since it's an operation you usually do quite often, you'd better automatize the process.

Most frameworks offer a way to make arguments parsing an easy task. You can build you own object for that. Quick and dirty example :

class Request
{

    // This is the spirit but you may want to make that cleaner :-)
    function get($key, $default=null, $from=null)
    {
         if ($from) :
             if (isset(${'_'.$from}[$key]));
                return sanitize(${'_'.strtoupper($from)}[$key]); // didn't test that but it should work
         else
             if isset($_REQUEST[$key])
                return sanitize($_REQUEST[$key]);

         return $default;
    }

    // basics. Enforce it with filters according to your needs
    function sanitize($data)
    {
          return addslashes(trim($data));
    }

    // your rules here
    function isEmptyString($data)
    {
        return (trim($data) === "" or $data === null);
    }


    function exists($key) {}

    function setFlash($name, $value) {}

    [...]

}

$request = new Request();
$question= $request->get('question', '', 'post');
print $request->isEmptyString($question);

Symfony use that kind of sugar massively.

But you are talking about more than that, with your "// Handle error here ". You are mixing 2 jobs : getting the data and processing it. This is not the same at all.

There are other mechanisms you can use to validate data. Again, frameworks can show you best pratices.

Create objects that represent the data of your form, then attach processses and fall back to it. It sounds far more work that hacking a quick PHP script (and it is the first time), but it's reusable, flexible, and much less error prone since form validation with usual PHP tends to quickly become spaguetti code.

When you just give make, it makes the first rule in your makefile, i.e "all". You have specified that "all" depends on "hello", which depends on main.o, factorial.o and hello.o. So 'make' tries to see if those files are present.

If they are present, 'make' sees if their dependencies, e.g. main.o has a dependency main.c, have changed. If they have changed, make rebuilds them, else skips the rule. Similarly it recursively goes on building the files that have changed and finally runs the top most command, "all" in your case to give you a executable, 'hello' in your case.

If they are not present, make blindly builds everything under the rule.

Coming to your problem, it isn't an error but 'make' is saying that every dependency in your makefile is up to date and it doesn't need to make anything!

It is not all about performance. Both C++ and C are used for embedded programming, sitting on top of hardware. If you would, for example, write an interrupt handler, you need to make sure that the code can be executed at once, without additional registers and/or memory pages being being swapped. That is when inline comes in handy. Good compilers do some "inlining" themselves when speed is needed, but "inline" compels them.

{} represents an empty dictionary, not an array/list. For lists or arrays, you need [].

To initialize an empty list do this:

my_list = []

or

my_list = list()

To add elements to the list, use append

my_list.append(12)

To extend the list to include the elements from another list use extend

my_list.extend([1,2,3,4])
my_list
--> [12,1,2,3,4]

To remove an element from a list use remove

my_list.remove(2)

Dictionaries represent a collection of key/value pairs also known as an associative array or a map.

To initialize an empty dictionary use {} or dict()

Dictionaries have keys and values

my_dict = {'key':'value', 'another_key' : 0}

To extend a dictionary with the contents of another dictionary you may use the update method

my_dict.update({'third_key' : 1})

To remove a value from a dictionary

del my_dict['key']

As others have suggested, you can directly write a 2-dimensional array into a Range on sheet, however if your array is single-dimensional then you have two options:

1. Convert your 1D array into a 2D array first, then print it on sheet (as a Range).
2. Convert your 1D array into a string and print it in a single cell (as a String).

Here is an example depicting both options:

Sub PrintArrayIn1Cell(myArr As Variant, cell As Range)
    cell = Join(myArr, ",")
End Sub
Sub PrintArrayAsRange(myArr As Variant, cell As Range)
    cell.Resize(UBound(myArr, 1), UBound(myArr, 2)) = myArr
End Sub
Sub TestPrintArrayIntoSheet()  '2dArrayToSheet
    Dim arr As Variant
    arr = Split("a  b  c", "  ")

    'Printing in ONE-CELL: To print all array-elements as a single string separated by comma (a,b,c):
    PrintArrayIn1Cell arr, [A1]

    'Printing in SEPARATE-CELLS: To print array-elements in separate cells:
    Dim arr2D As Variant
    arr2D = Application.WorksheetFunction.Transpose(arr) 'convert a 1D array into 2D array
    PrintArrayAsRange arr2D, Range("B1:B3")
End Sub

Note: Transpose will render column-by-column output, to get row-by-row output transpose it again - hope that makes sense.

HTH

Functions actually defined in other source files should only be declared in headers. In this case, you should use extern when declaring the prototype in a header.

Most of the time, your functions will be one of the following (more like a best practice):

• static (normal functions that aren't visible outside that .c file)
• static inline (inlines from .c or .h files)
• extern (declaration in headers of the next kind (see below))
• [no keyword whatsoever] (normal functions meant to be accessed using extern declarations)

Actually Just delete the build ( clean it ) , then restart the compiler , build it again problem solved .

You CAN add on click to dynamically created elements. Example below. Using a When to make sure its done. In my example, i'm grabbing a div with the class expand, adding a "click to see more" span, then using that span to hide/show the original div.

$.when($(".expand").before("<span class='clickActivate'>Click to see more</span>")).then(function(){
    $(".clickActivate").click(function(){
        $(this).next().toggle();
    })
});

using System.ComponentModel;

TypeConverter converter = TypeDescriptor.GetConverter(typeof(int));
string s = (string)converter.ConvertTo(i, typeof(string));

You can also use function:

//Works with negative numbers now
static int MyRound(double d) {
  if (d < 0) {
    return (int)(d - 0.5);
  }
  return (int)(d + 0.5);
}

Depending on the architecture it is several times faster.

On Mojave, I ran into errors with finding the SSL libraries, here's what finally worked without having to modify mysql_config:

sudo pip install MySQL-Python --global-option=build_ext --global-option="-I/usr/local/opt/openssl/include" --global-option="-L/usr/local/opt/openssl/lib"

Hopefully that will save someone a few hours of heartache

You can try this C++ code:

#include<stdlib.h>
#include<iostream>
#include<conio.h>
#include<fstream>
#using namespace std;

int main()
{
    int a;
    ofstream fcout ("big_file.txt");
    for(;;a += 1999999999){
        do{
            fcout << a;
        }
        while(!a);
    }
}

Maybe it will take some time to generate depending on your CPU speed...

I've found that in the majority of cases doing block clauses on one line is a bad idea.

It will, again as a generality, reduce the quality of the form of the code. High quality code form is a key language feature for python.

In some cases python will offer ways todo things on one line that are definitely more pythonic. Things such as what Nick D mentioned with the list comprehension:

newlist = [splitColon.split(a) for a in someList]

although unless you need a reusable list specifically you may want to consider using a generator instead

listgen = (splitColon.split(a) for a in someList)

note the biggest difference between the two is that you can't reiterate over a generator, but it is more efficient to use.

There is also a built in ternary operator in modern versions of python that allow you to do things like

string_to_print = "yes!" if "exam" in "example" else ""
print string_to_print

or

iterator = max_value if iterator > max_value else iterator

Some people may find these more readable and usable than the similar if (condition): block.

When it comes down to it, it's about code style and what's the standard with the team you're working on. That's the most important, but in general, i'd advise against one line blocks as the form of the code in python is so very important.

More an example:

$galleryIds = [1, '2', 'Vitruvian Man'];
$ids = array_filter($galleryIds, function($n){return (is_numeric($n));});
$ids = implode(', ', $ids);

$sql = "SELECT * FROM galleries WHERE id IN ({$ids})";
// output: 'SELECT * FROM galleries WHERE id IN (1, 2)'

$statement = $pdo->prepare($sql);
$statement->execute();

For completeness, using cut

cut -d : -f 2 <<< $var

And using only bash:

IFS=: read a b <<< $var ; echo $b

This:

<select style="width: XXXpx;">

XXX = Any Number

Works great in Google Chrome v70.0.3538.110

Shortest possible answer.

HTML

<a data-toggle="collapse" data-parent="#panel-quote-group" href="#collapseQuote">
    <span class="toggle-icon glyphicon glyphicon-collapse-up"></span>
</a>

JS:

<script type="text/javascript">
 $(function () {
     $('a[data-toggle="collapse"]').click(function () {
     $(this).find('span.toggle-icon').toggleClass('glyphicon-collapse-up glyphicon-collapse-down');
     })
 })
 </script>

And of course, you can use anything for a selector instead of anchor tag a and you can also use specific selector instead of this if your icon lies outside your clicked element.

If destroy() and clear() is not working (just like what i had experience) you can use jquery to remove the canvas and append it again.

    $('#chartAmazon').remove();
    $('#chartBar').append('<canvas id="chartAmazon"></canvas>');

    var ctxAmazon = $("#chartAmazon").get(0).getContext("2d");
      var AmazonChart = new Chart(ctxAmazon, {
        type: 'doughnut',
        data: dataAmazon,
        options: optionsA
    });

I think this might be the simplest solution:

<tr onclick="location.href='http://www.mywebsite.com'" style="cursor: pointer">
<td>...</td>
<td>...</td>
</tr>

The cursor CSS property sets the type of cursor, if any, to show when the mouse pointer is over an element.

The inline css defines that for that element the cursor will be formatted as a pointer, so you don't need the 'hover'.

just type

google-chrome

it works. Thanks.

You can use sorted function from Nspl:

use function \nspl\a\sorted;
use function \nspl\op\propertyGetter;
use function \nspl\op\methodCaller;

// Sort by property value
$sortedByCount = sorted($objects, propertyGetter('count'));

// Or sort by result of method call
$sortedByName = sorted($objects, methodCaller('getName'));

This adds a bit more randomness to the UUID generation but ensures each generated id is the same length

import org.apache.commons.codec.digest.DigestUtils;
import java.util.UUID;

public String createSalt() {
    String ts = String.valueOf(System.currentTimeMillis());
    String rand = UUID.randomUUID().toString();
    return DigestUtils.sha1Hex(ts + rand);
}

i figured out why RETURN is not unconditionally returning from the stored procedure. The error i'm seeing is while the stored procedure is being compiled - not when it's being executed.

Consider an imaginary stored procedure:

CREATE PROCEDURE dbo.foo AS

INSERT INTO ExistingTable
EXECUTE LinkedServer.Database.dbo.SomeProcedure

Even though this stord proedure contains an error (maybe it's because the objects have a differnet number of columns, maybe there is a timestamp column in the table, maybe the stored procedure doesn't exist), you can still save it. You can save it because you're referencing a linked server.

But when you actually execute the stored procedure, SQL Server then compiles it, and generates a query plan.

My error is not happening on line 114, it is on line 114. SQL Server cannot compile the stored procedure, that's why it's failing.

And that's why RETURN does not return, because it hasn't even started yet.

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

Microsoft recently modified the reflection API rendering most of these answers obsolete. The following should work on modern platforms (including Xamarin.Forms and UWP):

obj.GetType().GetTypeInfo().GetDeclaredMethod("MethodName").Invoke(obj, yourArgsHere);

Or as an extension method:

public static object InvokeMethod<T>(this T obj, string methodName, params object[] args)
{
    var type = typeof(T);
    var method = type.GetTypeInfo().GetDeclaredMethod(methodName);
    return method.Invoke(obj, args);
}

Note:

• If the desired method is in a superclass of obj the T generic must be explicitly set to the type of the superclass.

• If the method is asynchronous you can use await (Task) obj.InvokeMethod(…).

As my previous answer appeared not to be very popular, I will give this another go.

A short answer:

You are mostly on a right track. The shortest code to get to your desired output I could come up with is this:

things.stream()
      .map(this::resolve)
      .filter(Optional::isPresent)
      .findFirst()
      .flatMap( Function.identity() );

This will fit all your requirements:

1. It will find first response that resolves to a nonempty Optional<Result>
2. It calls this::resolve lazily as needed
3. this::resolve will not be called after first non-empty result
4. It will return Optional<Result>

Longer answer

The only modification compared to OP initial version was that I removed .map(Optional::get) before call to .findFirst() and added .flatMap(o -> o) as the last call in the chain.

This has a nice effect of getting rid of the double-Optional, whenever stream finds an actual result.

You can't really go any shorter than this in Java.

The alternative snippet of code using the more conventional for loop technique is going to be about same number of lines of code and have more or less same order and number of operations you need to perform:

1. Calling this.resolve,
2. filtering based on Optional.isPresent
3. returning the result and
4. some way of dealing with negative result (when nothing was found)

Just to prove that my solution works as advertised, I wrote a small test program:

public class StackOverflow {

    public static void main( String... args ) {
        try {
            final int integer = Stream.of( args )
                    .peek( s -> System.out.println( "Looking at " + s ) )
                    .map( StackOverflow::resolve )
                    .filter( Optional::isPresent )
                    .findFirst()
                    .flatMap( o -> o )
                    .orElseThrow( NoSuchElementException::new )
                    .intValue();

            System.out.println( "First integer found is " + integer );
        }
        catch ( NoSuchElementException e ) {
            System.out.println( "No integers provided!" );
        }
    }

    private static Optional<Integer> resolve( String string ) {
        try {
            return Optional.of( Integer.valueOf( string ) );
        }
        catch ( NumberFormatException e )
        {
            System.out.println( '"' + string + '"' + " is not an integer");
            return Optional.empty();
        }
    }

}

(It does have few extra lines for debugging and verifying that only as many calls to resolve as needed...)

Executing this on a command line, I got the following results:

$ java StackOferflow a b 3 c 4
Looking at a
"a" is not an integer
Looking at b
"b" is not an integer

I was similarly underwhelmed by this situation and ended up making my own Ubuntu source packages for this. These source packages allow you to easily produce a binary package. They are based on the latest gtest & gmock source as of this post.

Google Test DEB Source Package

Google Mock DEB Source Package

To build the binary package do this:

tar -xzvf gtest-1.7.0.tar.gz
cd gtest-1.7.0
dpkg-source -x gtest_1.7.0-1.dsc
cd gtest-1.7.0
dpkg-buildpackage

It may tell you that you need some pre-requisite packages in which case you just need to apt-get install them. Apart from that, the built .deb binary packages should then be sitting in the parent directory.

For GMock, the process is the same.

As a side note, while not specific to my source packages, when linking gtest to your unit test, ensure that gtest is included first (https://bbs.archlinux.org/viewtopic.php?id=156639) This seems like a common gotcha.

Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.

On a related note: I hate XCode.

Update: Use Xamarin Studio. It's solid.

If your git says you are commit ahead then just First,

git push origin

To make sure u have pushed all ur latest work in repo

Then,

git reset --hard origin/master

To reset and match up with the repo

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

All that's needed is that the format specifiers and the types agree, and you can always cast to make that true. long is at least 32 bits, so %lu together with (unsigned long)k is always correct:

uint32_t k;
printf("%lu\n", (unsigned long)k);

size_t is trickier, which is why %zu was added in C99. If you can't use that, then treat it just like k (long is the biggest type in C89, size_t is very unlikely to be larger).

size_t sz;
printf("%zu\n", sz);  /* C99 version */
printf("%lu\n", (unsigned long)sz);  /* common C89 version */

If you don't get the format specifiers correct for the type you are passing, then printf will do the equivalent of reading too much or too little memory out of the array. As long as you use explicit casts to match up types, it's portable.

train_test_split is part of the module sklearn.model_selection, hence, you may need to import the module from model_selection

Code:

from sklearn.model_selection import train_test_split

In the solution it is mentioned - "One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described."

For avoiding this -

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If we need to use another JavaScript library alongside jQuery, we can return control of $ back to the other library with a call to $.noConflict():

Use which:

 set.seed(1)
 x <- sample(10, 50, replace = TRUE)
 length(which(x > 3 & x < 5))
 # [1]  6

If using maven, just add to your pom.xml:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.5.0-b01</version>
</dependency>

Of course, you need to check the current version.

On Visual Studio Community 7.5.3 on Mac this works for me:

Ctrl + Space

Based on Tom Gullen´s answer.

var start = new Date("02/05/2013");
var end = new Date("02/10/2013");


var loop = new Date(start);
while(loop <= end){
   alert(loop);           

   var newDate = loop.setDate(loop.getDate() + 1);
   loop = new Date(newDate);
}

\ is an escape character in Python. \t gets interpreted as a tab. If you need \ character in a string, you have to use \\.

Your code should be:
test_file=open('c:\\Python27\\test.txt','r')

My code after reading a few above answers.

/**
 * Returns the given underscored_word_group as a Human Readable Word Group.
 * (Underscores are replaced by spaces and capitalized following words.)
 * 
 * @param pWord
 *            String to be made more readable
 * @return Human-readable string
 */
public static String humanize2(String pWord)
{
    StringBuilder sb = new StringBuilder();
    String[] words = pWord.replaceAll("_", " ").split("\\s");
    for (int i = 0; i < words.length; i++)
    {
        if (i > 0)
            sb.append(" ");
        if (words[i].length() > 0)
        {
            sb.append(Character.toUpperCase(words[i].charAt(0)));
            if (words[i].length() > 1)
            {
                sb.append(words[i].substring(1));
            }
        }
    }
    return sb.toString();
}

Since it is being passed a duration of 0, I suppose it is in order to remove the code passed to the setTimeout from the flow of execution. So if it's a function that could take a while, it won't prevent the subsequent code from executing.

The information provided in this answer can lead to insecure programming practices.

The information provided here depends highly on MySQL configuration, including (but not limited to) the program version, the database client and character-encoding used.

See http://dev.mysql.com/doc/refman/5.0/en/string-literals.html

MySQL recognizes the following escape sequences.
\0     An ASCII NUL (0x00) character.
\'     A single quote (“'”) character.
\"     A double quote (“"”) character.
\b     A backspace character.
\n     A newline (linefeed) character.
\r     A carriage return character.
\t     A tab character.
\Z     ASCII 26 (Control-Z). See note following the table.
\\     A backslash (“\”) character.
\%     A “%” character. See note following the table.
\_     A “_” character. See note following the table.

So you need

select * from tablename where fields like "%string \"hi\" %";

Although as Bill Karwin notes below, using double quotes for string delimiters isn't standard SQL, so it's good practice to use single quotes. This simplifies things:

select * from tablename where fields like '%string "hi" %';

In order to solve this problem, I recognize two solutions:

• The first one goes with AJAX, with which you'll have to load the template from another file and just add everytime you want with .clone().

  $.get('url/to/template', function(data) {
      temp = data
      $('.search').keyup(function() {
          $('.list-items').html(null);
  
          $.each(items, function(index) {
               $(this).append(temp.clone())
          });
  
      });
  });
  

  Take into account that the event should be added once the ajax has completed to be sure the data is available!

• The second one would be to directly add it anywhere in the original html, select it and hide it in jQuery:

  temp = $('.list_group_item').hide()
  

  You can after add a new instance of the template with

  $('.search').keyup(function() {
      $('.list-items').html(null);
  
      $.each(items, function(index) {
          $(this).append(temp.clone())
      });
  });
  

• Same as the previous one, but if you don't want the template to remain there, but just in the javascript, I think you can use (have not tested it!) .detach() instead of hide.

  temp = $('.list_group_item').detach()
  

  .detach() removes elements from the DOM while keeping the data and events alive (.remove() does not!).

AngularJS relies on input names to expose validation errors.

Unfortunately, as of today, it is not possible (without using a custom directive) to dynamically generate a name of an input. Indeed, checking input docs we can see that the name attribute accepts a string only.

To solve the 'dynamic name' problem you need to create an inner form (see ng-form):

<div ng-repeat="social in formData.socials">
      <ng-form name="urlForm">
            <input type="url" name="socialUrl" ng-model="social.url">
            <span class="alert error" ng-show="urlForm.socialUrl.$error.url">URL error</span>
      </ng-form>
  </div>

The other alternative would be to write a custom directive for this.

Here is the jsFiddle showing the usage of the ngForm: http://jsfiddle.net/pkozlowski_opensource/XK2ZT/2/

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;
          // if it is the receive timeout, then reading ended
          bytes = 0;
      }
  } while (bytes > 0);
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

To expand one what CheeseConQueso is saying, here are the entire steps to update a view using PHPMyAdmin:

1. Run the following query: SHOW CREATE VIEW your_view_name
2. Expand the options and choose Full Texts
3. Press Go
4. Copy entire contents of the Create View column.
5. Make changes to the query in the editor of your choice
6. Run the query directly (without the CREATE VIEW... syntax) to make sure it runs as you expect it to.
7. Once you're satisfied, click on your view in the list on the left to browse its data and then scroll all the way to the bottom where you'll see a CREATE VIEW link. Click that.
8. Place a check in the OR REPLACE field.
9. In the VIEW name put the name of the view you are going to update.
10. In the AS field put the contents of the query that you ran while testing (without the CREATE VIEW... syntax).
11. Press Go

I hope that helps somebody. Special thanks to CheesConQueso for his/her insightful answer.

To check if a Path exists to a directory, use this one:

$pathToDirectory = "c:\program files\blahblah\"
if (![System.IO.Directory]::Exists($pathToDirectory))
{
 mkdir $path1
}

To check if a Path to a file exists use what @Mathias suggested:

[System.IO.File]::Exists($pathToAFile)

I recommend trying to downgrade DJANGO to version 2.1.1.

One suggestion in other answers is to use ax.set_axis_bgcolor("red"). This however is deprecated, and doesn't work on MatPlotLib >= v2.0.

There is also the suggestion to use ax.patch.set_facecolor("red") (works on both MatPlotLib v1.5 & v2.2). While this works fine, an even easier solution for v2.0+ is to use

ax.set_facecolor("red")

In order to start a service in its own process, you must specify the following in the xml declaration.

<service
  android:name="WordService"
  android:process=":my_process" 
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

Simpler approach? A little more Pythonic?

>>> ok = "0123456789abcdef"
>>> all(c in ok for c in "123456abc")
True
>>> all(c in ok for c in "hello world")
False

It certainly isn't the most efficient, but it's sure readable.

If you would like to show it in a new window, you could use Tkinter + PIL library, like so:

import tkinter as tk
from PIL import ImageTk, Image

def show_imge(path):
    image_window = tk.Tk()
    img = ImageTk.PhotoImage(Image.open(path))
    panel = tk.Label(image_window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    image_window.mainloop()

This is a modified example that can be found all over the web.

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

PHP

unset($array[1]);

format is definitely the most elegant way, but afaik you can't use that with python's logging module, so here's how you can do it using the % formatting:

formatter = logging.Formatter(
    fmt='%(asctime)s | %(name)-20s | %(levelname)-10s | %(message)s',
)

Here, the - indicates left-alignment, and the number before s indicates the fixed width.

Some sample output:

Though you already had the answer, thought to add some info.

As you mentioned Collections explicitly, you can't use listIterator to get the index for all types of collections.

List interfaces - ArrayList, LinkedList, Vector and Stack.

Has both iterator() and listIterator()

Set interfaces - HashSet, LinkedHashSet, TreeSet and EnumSet.

Has only iterator()

Map interfaces - HashMap, LinkedHashMap, TreeMap and IdentityHashMap

Has no iterators, but can be iterated using through the keySet() / values() or entrySet() as keySet() and entrySet() returns Set and values() returns Collection.

So its better to use iterators() with continuous increment of a value to get the current index for any collection type.

You can use implode to return your array with a string separator.

$withComma = implode(",", $array);

echo $withComma;
// Will display apple,banana,orange

Use:

find . 2>/dev/null > files_and_folders

This hides not just the Permission denied errors, of course, but all error messages.

If you really want to keep other possible errors, such as too many hops on a symlink, but not the permission denied ones, then you'd probably have to take a flying guess that you don't have many files called 'permission denied' and try:

find . 2>&1 | grep -v 'Permission denied' > files_and_folders

If you strictly want to filter just standard error, you can use the more elaborate construction:

find . 2>&1 > files_and_folders | grep -v 'Permission denied' >&2

The I/O redirection on the find command is: 2>&1 > files_and_folders |. The pipe redirects standard output to the grep command and is applied first. The 2>&1 sends standard error to the same place as standard output (the pipe). The > files_and_folders sends standard output (but not standard error) to a file. The net result is that messages written to standard error are sent down the pipe and the regular output of find is written to the file. The grep filters the standard output (you can decide how selective you want it to be, and may have to change the spelling depending on locale and O/S) and the final >&2 means that the surviving error messages (written to standard output) go to standard error once more. The final redirection could be regarded as optional at the terminal, but would be a very good idea to use it in a script so that error messages appear on standard error.

There are endless variations on this theme, depending on what you want to do. This will work on any variant of Unix with any Bourne shell derivative (Bash, Korn, …) and any POSIX-compliant version of find.

If you wish to adapt to the specific version of find you have on your system, there may be alternative options available. GNU find in particular has a myriad options not available in other versions — see the currently accepted answer for one such set of options.

This is the procedure that seems simplest to me:

SharedPreferences sp = getSharedPreferences("MySharedPrefs", MODE_PRIVATE);
SharedPreferences.Editor e = sp.edit();

    if (sp.getString("sharedString", null).equals("true")
            || sp.getString("sharedString", null) == null) {
        e.putString("sharedString", "false").commit();
        // Do something
    } else {
        // Do something else
    }

Just in case this helps anybody else out there, I stumbled on an obscure case for this error triggering last night. Specifically, I was using the require_once method and specifying only a filename and no path, since the file being required was present in the same directory.

I started to get the 'Failed opening required file' error at one point. After tearing my hair out for a while, I finally noticed a PHP Warning message immediately above the fatal error output, indicating 'failed to open stream: Permission denied', but more importantly, informing me of the path to the file it was trying to open. I then twigged to the fact I had created a copy of the file (with ownership not accessible to Apache) elsewhere that happened to also be in the PHP 'include' search path, and ahead of the folder where I wanted it to be picked up. D'oh!

Based on my Comment here is one way to get what you want done:

Start byt selecting any cell in your range and Press Ctrl + T

This will give you this pop up:

make sure the Where is your table text is correct and click ok you will now have:

Now If you add a column header in D it will automatically be added to the table all the way to the last row:

Now If you enter a formula into this column:

After you enter it, the formula will be auto filled all the way to last row:

Now if you add a new row at the next row under your table:

Once entered it will be resized to the width of your table and all columns with formulas will be added also:

Hope this solves your problem!

If you are still working in Swift 1.x

then try,

let testArray = ["A","B","C"]

let indexOfA = find(testArray, "A") 
let indexOfB = find(testArray, "B")
let indexOfC = find(testArray, "C")

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

I don't think using "points" for font-size on a screen is a good idea. Try using px or em on font-size.

From W3C:

Do not specify the font-size in pt, or other absolute length units. They render inconsistently across platforms and can't be resized by the User Agent (e.g browser).

One gotcha to do with converting Base64 from a string is that some conversion functions use the preceding "data:image/jpg;base64," and others only accept the actual data.

What I would do, looking at your specific need:

Say you have list a with some values, and your keys are in the attribute x of the objects stored in list b

keys = {i:j.x for i,j in zip(a, b)}
a.sort(key=keys.__get_item__)

With this method you get your list ordered without having to construct the intermediate permutation list you were asking for.

1. Changes in the IDE's project folder does not immediately get reflected in the server's work folder. There's kind of a background job in the IDE which takes care that the server's work folder get synced with last updates (this is in IDE terms called "publishing"). This is the main cause of the problem you're seeing.

2. In real world code there are circumstances where storing uploaded files in the webapp's deploy folder will not work at all. Some servers do (either by default or by configuration) not expand the deployed WAR file into the local disk file system, but instead fully in the memory. You can't create new files in the memory without basically editing the deployed WAR file and redeploying it.

3. Even when the server expands the deployed WAR file into the local disk file system, all newly created files will get lost on a redeploy or even a simple restart, simply because those new files are not part of the original WAR file.

It really doesn't matter to me or anyone else where exactly on the local disk file system it will be saved, as long as you do not ever use getRealPath() method. Using that method is in any case alarming.

The path to the storage location can in turn be definied in many ways. You have to do it all by yourself. Perhaps this is where your confusion is caused because you somehow expected that the server does that all automagically. Please note that @MultipartConfig(location) does not specify the final upload destination, but the temporary storage location for the case file size exceeds memory storage threshold.

So, the path to the final storage location can be definied in either of the following ways:

• Hardcoded:

    File uploads = new File("/path/to/uploads");
  

• Environment variable via SET UPLOAD_LOCATION=/path/to/uploads:

    File uploads = new File(System.getenv("UPLOAD_LOCATION"));
  

• VM argument during server startup via -Dupload.location="/path/to/uploads":

    File uploads = new File(System.getProperty("upload.location"));
  

• *.properties file entry as upload.location=/path/to/uploads:

    File uploads = new File(properties.getProperty("upload.location"));
  

• web.xml <context-param> with name upload.location and value /path/to/uploads:

    File uploads = new File(getServletContext().getInitParameter("upload.location"));
  

• If any, use the server-provided location, e.g. in JBoss AS/WildFly:

    File uploads = new File(System.getProperty("jboss.server.data.dir"), "uploads");
  

Either way, you can easily reference and save the file as follows:

File file = new File(uploads, "somefilename.ext");

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath());
}

Or, when you want to autogenerate an unique file name to prevent users from overwriting existing files with coincidentally the same name:

File file = File.createTempFile("somefilename-", ".ext", uploads);

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath(), StandardCopyOption.REPLACE_EXISTING);
}

Note: do not use Part#write() as it interprets the path relative to the temporary storage location defined in @MultipartConfig(location).

If the file is coming off the disk and as others have stated, use the BaseName and Extension properties:

PS C:\> dir *.xlsx | select BaseName,Extension

BaseName                                Extension
--------                                ---------
StackOverflow.com Test Config           .xlsx  

If you are given the file name as part of string (say coming from a text file), I would use the GetFileNameWithoutExtension and GetExtension static methods from the System.IO.Path class:

PS C:\> [System.IO.Path]::GetFileNameWithoutExtension("Test Config.xlsx")
Test Config
PS H:\> [System.IO.Path]::GetExtension("Test Config.xlsx")
.xlsx

run pod install inside ios folder then go back to root folder and run npx react-native run-ios

It's better not to use refs in such cases. Use:

<input
    type="checkbox"
    checked={this.state.active}
    onClick={this.handleClick}
/>

There are some options:

checked vs defaultChecked

The former would respond to both state changes and clicks. The latter would ignore state changes.

onClick vs onChange

The former would always trigger on clicks. The latter would not trigger on clicks if checked attribute is present on input element.

• Ctrl + A and then Ctrl+D. Doing this will detach you from the screen session which you can later resume by doing screen -r.

• You can also do: Ctrl+A then type :. This will put you in screen command mode. Type the command detach to be detached from the running screen session.

.getBoundingClientRect() returns the size of an element and its position relative to the viewport.We can easily get following

• left, right
• top, bottom
• height, width

Example :

var element = d3.select('.elementClassName').node();
element.getBoundingClientRect().width;

Good question. I'm using the Bootstrap Dropdown Menu, and needed to execute an event when a Bootstrap Dropdown was hidden. When the dropdown is opened, the containing div with a class name of "button-group" adds a class of "open"; and the button itself has an "aria-expanded" attribute set to true. When the dropdown is closed, that class of "open" is removed from the containing div, and aria-expanded is switched from true to false.

That led me to this question, of how to detect the class change.

With Bootstrap, there are "Dropdown Events" that can be detected. Look for "Dropdown Events" at this link. http://www.w3schools.com/bootstrap/bootstrap_ref_js_dropdown.asp

Here is a quick-and-dirty example of using this event on a Bootstrap Dropdown.

$(document).on('hidden.bs.dropdown', function(event) {
    console.log('closed');
});

Now I realize this is more specific than the general question that's being asked. But I imagine other developers trying to detect an open or closed event with a Bootstrap Dropdown will find this helpful. Like me, they may initially go down the path of simply trying to detect an element class change (which apparently isn't so simple). Thanks.

As, i am installing through anaconda Prompt .In my case, it didn't even work with python -m pip install Then, i add this

python -m pip install <package_name> --user

It works for me.

Like: python -m pip install mitmproxy --user

Another you should try that run the Command Prompt as Run as Administrator and then try pip install. It should work either.

Do this :

<script type="text/javascript">
function showDetails(username)
{
   window.location = '/player_detail?username='+username;
}
</script>

<input type="button" name="theButton" value="Detail" onclick="showDetails('username');">

Add compat library compilation to the build.gradle file:

compile 'com.android.support:appcompat-v7:19.+'

Two examples of filtering out multiple lines with grep:

Put this in filename.txt:

abc
def
ghi
jkl

grep command using -E option with a pipe between tokens in a string:

grep -Ev 'def|jkl' filename.txt

prints:

abc
ghi

Command using -v option with pipe between tokens surrounded by parens:

egrep -v '(def|jkl)' filename.txt

prints:

abc
ghi

This is because, the amount of memory you wish to assign for JVM is not available or may be you are assigning more than available memory. Try small size then u can see the difference.
Try:

set JAVA_OPTS=-Xms128m -Xmx512m -XX:PermSize=128m

Another thing to remember is that request.POST['keyword'] refers to the element identified by the specified html name attribute keyword.

So, if your form is:

<form action="/login/" method="POST">
  <input type="text" name="keyword" placeholder="Search query">
  <input type="number" name="results" placeholder="Number of results">
</form>

then, request.POST['keyword'] and request.POST['results'] will contain the value of the input elements keyword and results, respectively.

I finished my time alert with a unwanted effect.... Browsers add stuff to windows. My script is an aptated one and I will show after the following text.

I found a CSS script for popups, which doesn't have unwanted browser stuff. This was written by Prakash:- https://codepen.io/imprakash/pen/GgNMXO. This script I will show after the following text.

This CSS script above looks professional and is alot more tidy. This button could be a clickable company logo image. By suppressing this button/image from running a function, this means you can run this function from inside javascript or call it with CSS, without it being run by clicking it.

This popup alert stays inside the window that popped it up. So if you are a multi-tasker you won't have trouble knowing what alert goes with what window.

The statements above are valid ones.... (Please allow). How these are achieved will be down to experimentation, as my knowledge of CSS is limited at the moment, but I learn fast.

CSS menus/DHTML use mouseover(valid statement).

I have a CSS menu script of my own which is adapted from 'Javascript for dummies' that pops up a menu alert. This works, but text size is limited. This hides under the top window banner. This could be set to be timed alert. This isn't great, but I will show this after the following text.

The Prakash script above I feel could be the answer if you can adapt it.

Scripts that follow:- My adapted timed window alert, Prakash's CSS popup script, my timed menu alert.

After some experimenting, I think the algorithm for LinearLayout is this:

Assume that weightSum is set to a value. The case of absence is discussed later.

First, divide the weightSum by the number of elements whith match_parent or fill_parent in the dimension of the LinearLayout (e.g. layout_width for orientation="horizontal"). We will call this value the weight multiplier for each element. The default value for weightSum is 1.0, so the default weight multiplier is 1/n, where n is the number of fill_parent elements; wrap_content elements do not contribute to n.

E.g. when weightSum is 60, and there are 3 fill_parent elements, the weight multiplier is 20. The weight multiplier is the default value for e.g. layout_width if the attribute is absent.

Second, the maximum possible expansion of every element is computed. First, the wrap_content elements are computed according to their contents. Their expansion is deducted from the expansion of the parent container. We will call the remainer expansion_remainer. This remainder is distributed among fill_parent elements according to their layout_weight.

Third, the expansion of every fill_parent element is computed as:

Example:

If weightSum is 60, and there are 3 fill_parent elements with the weigths 10, 20 and 30, their expansion on the screen is 2/3, 1/3 and 0/3 of the parent container.

weight | expansion
     0 | 3/3
    10 | 2/3
    20 | 1/3
    30 | 0/3
    40 | 0/3

The minimum expansion is capped at 0. The maximum expansion is capped at parent size, i.e. weights are capped at 0.

If an element is set to wrap_content, its expansion is calculated first, and the remaining expansion is subject to distribution among the fill_parent elements. If weightSum is set, this leads to layout_weight having no effect on wrap_content elements. However, wrap_content elements can still be pushed out of the visible area by elements whose weight is lower than (e.g. between 0-1 for weightSum= 1 or between 0-20 for the above example).

If no weightSum is specified, it is computed as the sum of all layout_weight values, including elements with wrap_content set! So having layout_weight set on wrap_content elements, can influence their expansion. E.g. a negative weight will shrink the other fill_parent elements. Before the fill_parent elements are laid out, will the above formula be applied to wrap_content elements, with maximum possible expansion being their expansion according to the wrapped content. The wrap_content elements will be shrunk, and afterwards the maximum possible expansion for the remaining fill_parent elements is computed and distributed.

This can lead to unintuitive results.

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

Using Kotlin, we can achieve by doing the following

I was looking for a simple solution to use for python 3.x and windows. There doesn't seem to be support from textract, which is unfortunate, but if you are looking for a simple solution for windows/python 3 checkout the tika package, really straight forward for reading pdfs.

Tika-Python is a Python binding to the Apache Tika™ REST services allowing Tika to be called natively in the Python community.

from tika import parser # pip install tika

raw = parser.from_file('sample.pdf')
print(raw['content'])

Note that Tika is written in Java so you will need a Java runtime installed

Working solution is by using in-build: panelClass attribute and set styles in global style.css (with !important):

https://material.angular.io/components/select/api

/* style.css */
.matRole .mat-option-text {
  height: 4em !important;
}

<mat-select panelClass="matRole">...

If you want to set the background using a hex color you could do this:

var bc = new BrushConverter();

myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");

Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:

<SolidColorBrush x:Key="BrushFFXXXXXX">#FF8D8A8A</SolidColorBrush>
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");

I looked for ways to do this and ended up choosing this way:

in the controller:
    @data_tables = ActiveRecord::Base.connection.tables

in the view:
  <% @data_tables.each do |dt|  %>
  <br>
  <%= dt %>
  <% end %>
  <br>

Yes, bool. It's not exactly the same -- '0' is True, but None, False, [], 0, 0.0, and "" are all False.

bool is used implicitly when you evaluate an object in a condition like an if or while statement, conditional expression, or with a boolean operator.

If you wanted to handle strings containing numbers as PHP does, you could do something like:

def empty(value):
    try:
        value = float(value)
    except ValueError:
        pass
    return bool(value)

I found a very interesting solution:

Here is an easy to understand permutaion function for both string and integer as input. With this you can even set your output length(which in normal case it is equal to input length)

String

    static ICollection<string> result;

    public static ICollection<string> GetAllPermutations(string str, int outputLength)
    {
        result = new List<string>();
        MakePermutations(str.ToCharArray(), string.Empty, outputLength);
        return result;
    }

    private static void MakePermutations(
       char[] possibleArray,//all chars extracted from input
       string permutation,
       int outputLength//the length of output)
    {
         if (permutation.Length < outputLength)
         {
             for (int i = 0; i < possibleArray.Length; i++)
             {
                 var tempList = possibleArray.ToList<char>();
                 tempList.RemoveAt(i);
                 MakePermutations(tempList.ToArray(), 
                      string.Concat(permutation, possibleArray[i]), outputLength);
             }
         }
         else if (!result.Contains(permutation))
            result.Add(permutation);
    }

and for Integer just change the caller method and MakePermutations() remains untouched:

    public static ICollection<int> GetAllPermutations(int input, int outputLength)
    {
        result = new List<string>();
        MakePermutations(input.ToString().ToCharArray(), string.Empty, outputLength);
        return result.Select(m => int.Parse(m)).ToList<int>();
    }

example 1: GetAllPermutations("abc",3); "abc" "acb" "bac" "bca" "cab" "cba"

example 2: GetAllPermutations("abcd",2); "ab" "ac" "ad" "ba" "bc" "bd" "ca" "cb" "cd" "da" "db" "dc"

example 3: GetAllPermutations(486,2); 48 46 84 86 64 68

The root cause is: HTML on a page have to loaded before javascript code. Resolving in 2 ways:

1) Allow HTML load before the js code.

<script type ="text/javascript">
    window.onload = function what(){
        document.getElementById('hello').innerHTML = 'hi';
    }
</script>

//or set time out like this:
<script type ="text/javascript">
    setTimeout(function(){
       what();
       function what(){
          document.getElementById('hello').innerHTML = 'hi';
       };
    }, 50);
    //NOTE: 50 is milisecond.
</script>

2) Move js code under HTML code

<div id="hello"></div>
<script type ="text/javascript">
    what();
    function what(){
        document.getElementById('hello').innerHTML = 'hi';
    };
</script>

I have created this easy to use library that does exactly what you are looking for: ss-search

import { search } from "ss-search"

const data = [
  {
       "foo" : "bar",
       "bar" : "sit"
  },
  {
       "foo" : "lorem",
       "bar" : "ipsum"
  },
  {
       "foo" : "dolor",
       "bar" : "amet"
  }
]
const searchKeys = ["foor", "bar"] 
const searchText = "dolor"

const results = search(data, keys, searchText)
// results: [{ "foo": "dolor", "bar": "amet" }]

A simple git fetch --tags worked for me.

Here is angular2-cookie which is the exact implementation of Angular 1 $cookies service (plus a removeAll() method) that I created. It is using the same methods, only implemented in typescript with Angular 2 logic.

You can inject it as a service in the components providers array:

import {CookieService} from 'angular2-cookie/core';

@Component({
    selector: 'my-very-cool-app',
    template: '<h1>My Angular2 App with Cookies</h1>',
    providers: [CookieService]
})

After that, define it in the consturctur as usual and start using:

export class AppComponent { 
  constructor(private _cookieService:CookieService){}

  getCookie(key: string){
    return this._cookieService.get(key);
  }
}

You can get it via npm:

npm install angular2-cookie --save

You can write your own rule!

 // add the rule here
 $.validator.addMethod("valueNotEquals", function(value, element, arg){
  return arg !== value;
 }, "Value must not equal arg.");

 // configure your validation
 $("form").validate({
  rules: {
   SelectName: { valueNotEquals: "default" }
  },
  messages: {
   SelectName: { valueNotEquals: "Please select an item!" }
  }  
 });

This basically does the same as Mvins answer, but is a more compressed down and simplified version. It works by going back the distance of the radius of the lines adjacent to the corner and connecting both ends with a bezier curve whose control point is at the original corner point.

function createRoundedPath(coords, radius, close) {
  let path = ""
  const length = coords.length + (close ? 1 : -1)
  for (let i = 0; i < length; i++) {
    const a = coords[i % coords.length]
    const b = coords[(i + 1) % coords.length]
    const t = Math.min(radius / Math.hypot(b.x - a.x, b.y - a.y), 0.5)

    if (i > 0) path += `Q${a.x},${a.y} ${a.x * (1 - t) + b.x * t},${a.y * (1 - t) + b.y * t}`

    if (!close && i == 0) path += `M${a.x},${a.y}`
    else if (i == 0) path += `M${a.x * (1 - t) + b.x * t},${a.y * (1 - t) + b.y * t}`

    if (!close && i == length - 1) path += `L${b.x},${b.y}`
    else if (i < length - 1) path += `L${a.x * t + b.x * (1 - t)},${a.y * t + b.y * (1 - t)}`
  }
  if (close) path += "Z"
  return path
}

The your seems a multi-array, not a JSON object.

If you want access the object like an array, you have to use some sort of key/value, such as:

var JSONObject = {
  "city": ["Blankaholm, "Gamleby"],
  "date": ["2012-10-23", "2012-10-22"],
  "description": ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
  "lat": ["57.586174","16.521841"], 
  "long": ["57.893162","16.406090"]
}

and access it with:

JSONObject.city[0] // => Blankaholm
JSONObject.date[1] // => 2012-10-22

and so on...

or

JSONObject['city'][0] // => Blankaholm
JSONObject['date'][1] // => 2012-10-22

and so on...

or, in last resort, if you don't want change your structure, you can do something like that:

var JSONObject = {
  "data": [
    ["Blankaholm, "Gamleby"],
    ["2012-10-23", "2012-10-22"],
    ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
    ["57.586174","16.521841"], 
    ["57.893162","16.406090"]
  ]
}

JSONObject.data[0][1] // => Gambleby

If you have iAds in your binary you will not be able to run it on anything before iOS 4.0 and it will be rejected if you try and submit a binary like this.

You can still run the simulator from 3.2 onwards after upgrading.

In the iPhone Simulator try selecting Hardware -> Version -> 3.2

I had the same issue. When compared the java version mentioned in the pom.xml file is different and the JAVA_HOME env variable was pointing to different version of jdk.

Have the JAVA_HOME and pom.xml updated to the same jdk installation path

import sys
import time

a = 0  
for x in range (0,3):  
    a = a + 1  
    b = ("Loading" + "." * a)
    # \r prints a carriage return first, so `b` is printed on top of the previous line.
    sys.stdout.write('\r'+b)
    time.sleep(0.5)
print (a)

Note that you might have to run sys.stdout.flush() right after sys.stdout.write('\r'+b) depending on which console you are doing the printing to have the results printed when requested without any buffering.

Have you tried rebooting since you set the environment variable?

It appears that Windows keeps it's environment variable in some sort of cache, and rebooting is one method to refresh it. I'm not sure but there may be a different method, but if you are not going to be changing your variable value too often this may be good enough.

First of all you should not merge the Fluent Api with the data annotation so I would suggest you to use one of the below:

make sure you have correclty set the keys

modelBuilder.Entity<Foo>()
            .HasKey(p => new { p.Name, p.Id });
modelBuilder.Entity<Foo>().Property(p => p.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);

OR you can achieve it using data annotation as well

public class Foo
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    [Key, Column(Order = 0)]
    public int Id { get; set; }

    [Key, Column(Order = 1)]
    public string Name{ get; set; }
}

I like the Infragistics controls. The WebDropDown has what you need. The only drawback is they can be a bit spendy.

mailx -a /path/to/file email@address

You might go into interactive mode (it will prompt you with "Subject: " and then a blank line), enter a subject, then enter a body and hit Ctrl+D (EOT) to finish.

You can do this: If your tomcat installation is default and you have not done any changes, then the default war will be ROOT.war. Thus whenever you will call http://yourserver.example.com/, it will call the index.html or index.jsp of your default WAR file. Make the following changes in your webapp/ROOT folder for redirecting requests to http://yourserver.example.com/somewhere/else:

1. Open webapp/ROOT/WEB-INF/web.xml, remove any servlet mapping with path /index.html or /index.jsp, and save.

2. Remove webapp/ROOT/index.html, if it exists.

3. Create the file webapp/ROOT/index.jsp with this line of content:

   <% response.sendRedirect("/some/where"); %>
   

   or if you want to direct to a different server,

   <% response.sendRedirect("http://otherserver.example.com/some/where"); %>
   

That's it.

Using an ungreedy match is a good start, but I'd also suggest that you reconsider any use of .* -- what about this?

groups = re.search(r"\([^)]*\)", x)

git reset does know five "modes": soft, mixed, hard, merge and keep. I will start with the first three, since these are the modes you'll usually encounter. After that you'll find a nice little a bonus, so stay tuned.

soft

When using git reset --soft HEAD~1 you will remove the last commit from the current branch, but the file changes will stay in your working tree. Also the changes will stay on your index, so following with a git commit will create a commit with the exact same changes as the commit you "removed" before.

mixed

This is the default mode and quite similar to soft. When "removing" a commit with git reset HEAD~1 you will still keep the changes in your working tree but not on the index; so if you want to "redo" the commit, you will have to add the changes (git add) before commiting.

hard

When using git reset --hard HEAD~1 you will lose all uncommited changes in addition to the changes introduced in the last commit. The changes won't stay in your working tree so doing a git status command will tell you that you don't have any changes in your repository.

Tread carefully with this one. If you accidentally remove uncommited changes which were never tracked by git (speak: committed or at least added to the index), you have no way of getting them back using git.

Bonus

keep

git reset --keep HEAD~1 is an interesting and useful one. It only resets the files which are different between the current HEAD and the given commit. It aborts the reset if one or more of these files has uncommited changes. It basically acts as a safer version of hard.

You can read more about that in the git reset documentation.

Note
When doing git reset to remove a commit the commit isn't really lost, there just is no reference pointing to it or any of it's children. You can still recover a commit which was "deleted" with git reset by finding it's SHA-1 key, for example with a command such as git reflog.

You can also put the files or links into the root of the solution explorer and then set the files properties:

Build action = Content

and

Copy to Output Directory = Copy if newer (for example)

For a link drag the file from the windows explorer into the solution explorer holding down the shift and control keys.

I haven't hit against this problem myself, but I'd spawn a thread at program start which immediately tries to generate a seed, then dies. The method which you call for randoms will join to that thread if it is alive so the first call only blocks if it occurs very early in program execution.

It is a dummy table with one element in it. It is useful because Oracle doesn't allow statements like

 SELECT 3+4

You can work around this restriction by writing

 SELECT 3+4 FROM DUAL

instead.

Lets say your HTML looks something like this:

<div class="box">
    <!-- stuff -->
    <p class="bet_time">Bet 5 days ago</p>
</div>

Then, with CSS, you can make that text appear in the bottom right like so:

.box {
    position:relative;
}
.bet_time {
    position:absolute;
    bottom:0;
    right:0;
}

The way this works is that absolutely positioned elements are always positioned with respect to the first relatively positioned parent element, or the window. Because we set the box's position to relative, .bet_time positions its right edge to the right edge of .box and its bottom edge to the bottom edge of .box

Luckily, the package-info class isn't required. I was able to fix mine problem with iowatiger08 solution.

Here is my fix showing the error message to help join the dots for some.

Error message

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://global.aon.bz/schema/cbs/archive/errorresource/0", local:"errorresource"). Expected elements are <{}errorresource>

Code before fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource")
public class Errorresource

Code after fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource", namespace="http://global.aon.bz/schema/cbs/archive/errorresource/0")
public class Errorresource

You can see the namespace added to @XmlRootElement as indicated in the error message.

Just thought i would share a solution also based on this that works with the Knowntype attribute using reflection , had to get derived class from any base class, solution can benefit from recursion to find the best matching class though i didn't need it in my case, matching is done by the type given to the converter if it has KnownTypes it will scan them all until it matches a type that has all the properties inside the json string, first one to match will be chosen.

usage is as simple as:

 string json = "{ Name:\"Something\", LastName:\"Otherthing\" }";
 var ret  = JsonConvert.DeserializeObject<A>(json, new KnownTypeConverter());

in the above case ret will be of type B.

JSON classes:

[KnownType(typeof(B))]
public class A
{
   public string Name { get; set; }
}

public class B : A
{
   public string LastName { get; set; }
}

Converter code:

/// <summary>
    /// Use KnownType Attribute to match a divierd class based on the class given to the serilaizer
    /// Selected class will be the first class to match all properties in the json object.
    /// </summary>
    public  class KnownTypeConverter : JsonConverter
    {
        public override bool CanConvert(Type objectType)
        {
            return System.Attribute.GetCustomAttributes(objectType).Any(v => v is KnownTypeAttribute);
        }

        public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
        {
            // Load JObject from stream
            JObject jObject = JObject.Load(reader);

            // Create target object based on JObject
            System.Attribute[] attrs = System.Attribute.GetCustomAttributes(objectType);  // Reflection. 

                // Displaying output. 
            foreach (System.Attribute attr in attrs)
            {
                if (attr is KnownTypeAttribute)
                {
                    KnownTypeAttribute k = (KnownTypeAttribute) attr;
                    var props = k.Type.GetProperties();
                    bool found = true;
                    foreach (var f in jObject)
                    {
                        if (!props.Any(z => z.Name == f.Key))
                        {
                            found = false;
                            break;
                        }
                    }

                    if (found)
                    {
                        var target = Activator.CreateInstance(k.Type);
                        serializer.Populate(jObject.CreateReader(),target);
                        return target;
                    }
                }
            }
            throw new ObjectNotFoundException();


            // Populate the object properties

        }

        public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
        {
            throw new NotImplementedException();
        }
    }

     .filter("Status=3");

The External Dependencies folder is populated by IntelliSense: the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).

You need to actually include the header (using a #include directive) to use it. Depending on what that header is, you may also need to add its containing folder to the "Additional Include Directories" property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties). You should compare the properties with those of the project that does build to determine what you need to add.

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015 > 01/02/2016 because 09 > 01. You need to either put your date in a comparable string format or compare DateTime objects which are comparable.

<?php
 $date_now = date("Y-m-d"); // this format is string comparable

if ($date_now > '2016-01-02') {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Or

<?php
 $date_now = new DateTime();
 $date2    = new DateTime("01/02/2016");

if ($date_now > $date2) {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Approach 1: (no longer works)

https://plus.google.com/s2/photos/profile/<user_id>?sz=<your_desired_size>

Approach 2: (each request counts in your api rate limits which is 10k requests per day for free)

https://www.googleapis.com/plus/v1/people/<user_id>?fields=image&key={YOUR_API_KEY}

with the following response format:

{ "image": { "url": "lh5.googleusercontent.com/-keLR5zGxWOg/.../photo.jpg?sz=50"; } }

Approach 3: (donot require api key)

http://picasaweb.google.com/data/entry/api/user/<user_id>?alt=json

in the json response you get a property named "gphoto$thumbnail", which contains the profile picture url like the following:

http://lh6.ggpht.com/-btLsReiDeF0/AAAAAAAAAAI/AAAAAAAAAAA/GXBpycNk984/s64-c/filename.jpg

You may notice in the url the portion "s64-c" which means the image size to be 64, I've tried using other values like "s100-c" and they worked. Also if you remove the "s64-c" part and append the "?sz=100" parameter, that will also work as of now. Though this is not very good way of getting the profile picture of a gplus user, but the advantage is it do not require any api key.

In case where multiple columns identify unique row (e.g relations table ) there you can use following

Use row id e.g. emp_dept(empid, deptid, startdate, enddate) suppose empid and deptid are unique and identify row in that case

select oed.empid, count(oed.empid) 
from emp_dept oed 
where exists ( select * 
               from  emp_dept ied 
                where oed.rowid <> ied.rowid and 
                       ied.empid = oed.empid and 
                      ied.deptid = oed.deptid )  
        group by oed.empid having count(oed.empid) > 1 order by count(oed.empid);

and if such table has primary key then use primary key instead of rowid, e.g id is pk then

select oed.empid, count(oed.empid) 
from emp_dept oed 
where exists ( select * 
               from  emp_dept ied 
                where oed.id <> ied.id and 
                       ied.empid = oed.empid and 
                      ied.deptid = oed.deptid )  
        group by oed.empid having count(oed.empid) > 1 order by count(oed.empid);

It's a simple problem. When you are running from terminal, you are running the php file from terminal as a privileged user. When you go to the php from your web browser, the php script is being run as the web server user which does not have permissions to execute files in your home directory. In Ubuntu, the www-data user is the apache web server user. If you're on ubuntu you would have to do the following: chown yourusername:www-data /home/testuser/testscript chmod g+x /home/testuser/testscript

what the above does is transfers user ownership of the file to you, and gives the webserver group ownership of it. the next command gives the group executable permission to the file. Now the next time you go ahead and do it from the browser, it should work.

Why do you need a span in this case? If you want to style the height could you just use a div? You might try a div with display: inline, although that might have the same issue since you'd in effect be doing the same thing as a span.

You can also get all fragments like this:

For v4 fragmets

List<Fragment> allFragments = getSupportFragmentManager().getFragments();

For app.fragment

List<Fragment> allFragments = getFragmentManager().getFragments();

In my opinion, in this case, it's better to use rake db:rollback, then edit your migration and again run rake db:migrate.

However, if you have data in the column you don't want to lose, then use rename_column.

If you want to "code golf" you can make a shorter version of some of the other answers here:

const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

But really the ideal answer in my opinion is to use Node's util library and its promisify function, which is designed for exactly this sort of thing (making promise-based versions of previously existing non-promise-based stuff):

const util = require('util');
const sleep = util.promisify(setTimeout);

In either case you can then pause simply by using await to call your sleep function:

await sleep(1000); // sleep for 1s/1000ms

If you are using Git Gui on windows,

1. Abort the merge
2. Make sure you are on your target branch
3. Delete the conflicting file from explorer
4. Rescan for changes in Git Gui (F5)
5. Notice that conflicting file is deleted
6. Select Stage Changed Files To Commit (Ctrl-I) from Commit menu
7. Enter a commit comment like "deleted conflicting file"
8. Commit (ctrl-enter)
9. Now if you restart the merge it will (hopefully) work.

There is no direct method to draw a triangle. You can use drawPolygon() method for this. It takes three parameters in the following form: drawPolygon(int x[],int y[], int number_of_points); To draw a triangle: (Specify the x coordinates in array x and y coordinates in array y and number of points which will be equal to the elements of both the arrays.Like in triangle you will have 3 x coordinates and 3 y coordinates which means you have 3 points in total.) Suppose you want to draw the triangle using the following points:(100,50),(70,100),(130,100) Do the following inside public void paint(Graphics g):

int x[]={100,70,130};
int y[]={50,100,100};
g.drawPolygon(x,y,3);

Similarly you can draw any shape using as many points as you want.

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

Try this

> dt.columns.Add("ColumnName", typeof(Give the type you want));
> dt.Rows[give the row no like  or  or any no]["Column name in which you want to add data"] = Value;

Or just simply add a span tag with the height of the fixed header set as its height then insert it next to the sticky header:

$(function() {
  var $span_height = $('.fixed-header').height;
  var $span_tag = '<span style="display:block; height:' + $span_height + 'px"></span>';

  $('.fixed-header').after($span_tag);
});

To find them, you can use this

;WITH cte AS
(
   SELECT 0 AS CharCode
   UNION ALL
   SELECT CharCode + 1 FROM cte WHERE CharCode <31
)
SELECT
   *
FROM
   mytable T
     cross join cte
WHERE
   EXISTS (SELECT *
        FROM mytable Tx
        WHERE Tx.PKCol = T.PKCol
             AND
              Tx.MyField LIKE '%' + CHAR(cte.CharCode) + '%'
         )

Replacing the EXISTS with a JOIN will allow you to REPLACE them, but you'll get multiple rows... I can't think of a way around that...

To answer the question literally (since GitHub is not in the question title), also be aware of this post over on superuser. EDIT: Answer copied here in relevant part, slightly modified for clarity in square brackets:

You're getting rejected because you're trying to delete the branch that your origin has currently "checked out".

If you have direct access to the repo, you can just open up a shell [in the bare repo] directory and use good old git branch to see what branch origin is currently on. To change it to another branch, you have to use git symbolic-ref HEAD refs/heads/another-branch.

Example of calculating time:

work-start   work-stop   lunchbreak    effective time

  07:30:00    17:00:00          1.5                 8  [=((A2-A1)*24)-A3]

If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.

In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).

Metrics and Svens answer deals with the usual situation but for us who work in non-english enviroments if you have exotic characters (å,ä,ö) in your character variable you will get the same result, even if you have multiple factor levels.

This is probably a bug.

You can configure the ObjectMapper to convert camel case to names with an underscore:

objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);

Or annotate a specific model class with this annotation:

@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy.class)

Before Jackson 2.7, the constant was named:

PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES

Your form is being submitted already as your button is type submit. Which in most browsers would result in a form submission and loading of the server response rather than executing javascript on the page.

Change the type of the submit button to a button. Also, as this button is given the id submit, it will cause a conflict with Javascript's submit function. Change the id of this button. Try something like

<input type="button" value="Submit" id="btnsubmit" onclick="submitForm()">

Another issue in this instance is that the name of the form contains a - dash. However, Javascript translates - as a minus.

You will need to either use array based notation or use document.getElementById() / document.getElementsByName(). The getElementById() function returns the element instance directly as Id is unique (but it requires an Id to be set). The getElementsByName() returns an array of values that have the same name. In this instance as we have not set an id, we can use the getElementsByName with index 0.

Try the following

function submitForm() {
   // Get the first form with the name
   // Usually the form name is not repeated
   // but duplicate names are possible in HTML
   // Therefore to work around the issue, enforce the correct index
   var frm = document.getElementsByName('contact-form')[0];
   frm.submit(); // Submit the form
   frm.reset();  // Reset all form data
   return false; // Prevent page refresh
}

Not only can you, but you have to make a special effort not to if you don't want to. :-)

When the browser encounters a classic script tag when parsing the HTML, it stops parsing and hands over to the JavaScript interpreter, which runs the script. The parser doesn't continue until the script execution is complete (because the script might do document.write calls to output markup that the parser should handle).

That's the default behavior, but you have a few options for delaying script execution:

1. Use JavaScript modules. A type="module" script is deferred until the HTML has been fully parsed and the initial DOM created. This isn't the primary reason to use modules, but it's one of the reasons:

   <script type="module" src="./my-code.js"></script>
   <!-- Or -->
   <script type="module">
   // Your code here
   </script>
   

   The code will be fetched (if it's separate) and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. (If your module code is inline rather than in its own file, it is also deferred until HTML parsing is complete.)

   This wasn't available when I first wrote this answer in 2010, but here in 2020, all major modern browsers support modules natively, and if you need to support older browsers, you can use bundlers like Webpack and Rollup.js.

2. Use the defer attribute on a classic script tag:

   <script defer src="./my-code.js"></script>
   

   As with the module, the code in my-code.js will be fetched and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. But, defer doesn't work with inline script content, only with external files referenced via src.

3. I don't think it's what you want, but you can use the async attribute to tell the browser to fetch the JavaScript code in parallel with the HTML parsing, but then run it as soon as possible, even if the HTML parsing isn't complete. You can put it on a type="module" tag, or use it instead of defer on a classic script tag.

4. Put the script tag at the end of the document, just prior to the closing </body> tag:

   <!doctype html>
   <html>
   <!-- ... -->
   <body>
   <!-- The document's HTML goes here -->
   <script type="module" src="./my-code.js"></script><!-- Or inline script -->
   </body>
   </html>
   

   That way, even though the code is run as soon as its encountered, all of the elements defined by the HTML above it exist and are ready to be used.

   It used to be that this caused an additional delay on some browsers because they wouldn't start fetching the code until the script tag was encountered, but modern browsers scan ahead and start prefetching. Still, this is very much the third choice at this point, both modules and defer are better options.

The spec has a useful diagram showing a raw script tag, defer, async, type="module", and type="module" async and the timing of when the JavaScript code is fetched and run:

Here's an example of the default behavior, a raw script tag:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script>_x000D_
    if (typeof NodeList !== "undefined" && !NodeList.prototype.forEach) {_x000D_
        NodeList.prototype.forEach = Array.prototype.forEach;_x000D_
    }_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

(See my answer here for details around that NodeList code.)

When you run that, you see "Paragraph 1" in green but "Paragraph 2" is black, because the script ran synchronously with the HTML parsing, and so it only found the first paragraph, not the second.

In contrast, here's a type="module" script:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script type="module">_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

Notice how they're both green now; the code didn't run until HTML parsing was complete. That would also be true with a defer script with external content (but not inline content).

(There was no need for the NodeList check there because any modern browser supporting modules already has forEach on NodeList.)

In this modern world, there's no real value to the DOMContentLoaded event of the "ready" feature that PrototypeJS, jQuery, ExtJS, Dojo, and most others provided back in the day (and still provide); just use modules or defer. Even back in the day, there wasn't much reason for using them (and they were often used incorrectly, holding up page presentation while the entire jQuery library was loaded because the script was in the head instead of after the document), something some developers at Google flagged up early on. This was also part of the reason for the YUI recommendation to put scripts at the end of the body, again back in the day.

You can use twitter search page to bypass 3,200 limit. However you have to scroll down many times in the search results page. For example, I searched tweets from @beyinsiz_adam. This is the link of search results: https://twitter.com/search?q=from%3Abeyinsiz_adam&src=typd&f=realtime

Now in order to scroll down many times, you can use the following javascript code.

    var myVar=setInterval(function(){myTimer()},1000);
    function myTimer() {
        window.scrollTo(0,document.body.scrollHeight);
    }

Just run it in the FireBug console. And wait some time to load all tweets.

The JSONArray.length() returns the number of elements in the JSONObject contained in the Array. Not the size of the array itself.

Example of AngularJS "global variables" using $rootScope:

Controller 1 sets the global variable:

function MyCtrl1($scope, $rootScope) {
    $rootScope.name = 'anonymous'; 
}

Controller 2 reads the global variable:

function MyCtrl2($scope, $rootScope) {
    $scope.name2 = $rootScope.name; 
}

Every single persons suggestion to run a query in Oracle to find records whose specific field is just blank, (this is not including (null) or any other field just a blank line) did not work. I tried every single suggested code. Guess I will keep searching online.

*****UPDATE*****

I tried this and it worked, not sure why it would not work if < 1 but for some reason < 2 worked and only returned records whose field is just blank

select [columnName] from [tableName] where LENGTH(columnName) < 2 ;

I am guessing whatever script that was used to convert data over has left something in the field even though it shows blank, that is my guess anyways as to why the < 2 works but not < 1

However, if you have any other values in that column field that is less than two characters then you might have to come up with another solution. If there are not a lot of other characters then you can single them out.

Hope my solution helps someone else out there some day.

(For those coming to this question from a search engine), check that your stored procedures declare a custom delimiter, as this is the error that you might see when the engine can't figure out how to terminate a statement:

    SELECT @sqlstr;
    PREPARE stmt FROM @sqlstr;

Try wrapping with a custom DELIMITER:

DROP PROCEDURE IF EXISTS prc_test;
DELIMITER $$
CREATE PROCEDURE prc_test( test varchar(50))
BEGIN
    SET @sqlstr = CONCAT_WS(' ', 'CREATE DATABASE',  test, 'CHARACTER SET utf8 COLLATE utf8_general_ci');
    SELECT @sqlstr;

TL;DR

Java caches boxed Integer instances from -128 to 127. Since you are using == to compare objects references instead of values, only cached objects will match. Either work with long unboxed primitive values or use .equals() to compare your Long objects.

Long (pun intended) version

Why there is problem in comparing Long variable with value greater than 127? If the data type of above variable is primitive (long) then code work for all values.

Java caches Integer objects instances from the range -128 to 127. That said:

• If you set to N Long variables the value 127 (cached), the same object instance will be pointed by all references. (N variables, 1 instance)
• If you set to N Long variables the value 128 (not cached), you will have an object instance pointed by every reference. (N variables, N instances)

That's why this:

Long val1 = 127L;
Long val2 = 127L;

System.out.println(val1 == val2);

Long val3 = 128L;
Long val4 = 128L;

System.out.println(val3 == val4);

Outputs this:

true
false

For the 127L value, since both references (val1 and val2) point to the same object instance in memory (cached), it returns true.

On the other hand, for the 128 value, since there is no instance for it cached in memory, a new one is created for any new assignments for boxed values, resulting in two different instances (pointed by val3 and val4) and returning false on the comparison between them.

That happens solely because you are comparing two Long object references, not long primitive values, with the == operator. If it wasn't for this Cache mechanism, these comparisons would always fail, so the real problem here is comparing boxed values with == operator.

Changing these variables to primitive long types will prevent this from happening, but in case you need to keep your code using Long objects, you can safely make these comparisons with the following approaches:

System.out.println(val3.equals(val4));                     // true
System.out.println(val3.longValue() == val4.longValue());  // true
System.out.println((long)val3 == (long)val4);              // true

(Proper null checking is necessary, even for castings)

IMO, it's always a good idea to stick with .equals() methods when dealing with Object comparisons.

If you want to see the environment variable you just set, you need to open a new command window.

Variables set with setx variables are available in future command windows only, not in the current command window. (Setx, Examples)

It isn't clear why you want to do this without sink, but you can wrap any commands in the invisible() function and it will suppress the output. For instance:

1:10 # prints output
invisible(1:10) # hides it

Otherwise, you can always combine things into one line with a semicolon and parentheses:

{ sink("/dev/null"); ....; sink(); }

I use someting like that: (Xamarin and C# code)

  LinearLayout linLayout= new LinearLayout(this); 
    linLayout.SetGravity(GravityFlags.Center);

    TextView txtView= new TextView(this);  
     linLayout.AddView(txtView); 

the SetGravity puts my textView in the center of the layout. So SetGravity layout property refer to layout content

token_type is a parameter in Access Token generate call to Authorization server, which essentially represents how an access_token will be generated and presented for resource access calls. You provide token_type in the access token generation call to an authorization server.

If you choose Bearer (default on most implementation), an access_token is generated and sent back to you. Bearer can be simply understood as "give access to the bearer of this token." One valid token and no question asked. On the other hand, if you choose Mac and sign_type (default hmac-sha-1 on most implementation), the access token is generated and kept as secret in Key Manager as an attribute, and an encrypted secret is sent back as access_token.

Yes, you can use your own implementation of token_type, but that might not make much sense as developers will need to follow your process rather than standard implementations of OAuth.

In summary, the yield statement transforms your function into a factory that produces a special object called a generator which wraps around the body of your original function. When the generator is iterated, it executes your function until it reaches the next yield then suspends execution and evaluates to the value passed to yield. It repeats this process on each iteration until the path of execution exits the function. For instance,

def simple_generator():
    yield 'one'
    yield 'two'
    yield 'three'

for i in simple_generator():
    print i

simply outputs

one
two
three

The power comes from using the generator with a loop that calculates a sequence, the generator executes the loop stopping each time to 'yield' the next result of the calculation, in this way it calculates a list on the fly, the benefit being the memory saved for especially large calculations

Say you wanted to create a your own range function that produces an iterable range of numbers, you could do it like so,

def myRangeNaive(i):
    n = 0
    range = []
    while n < i:
        range.append(n)
        n = n + 1
    return range

and use it like this;

for i in myRangeNaive(10):
    print i

But this is inefficient because

• You create an array that you only use once (this wastes memory)
• This code actually loops over that array twice! :(

Luckily Guido and his team were generous enough to develop generators so we could just do this;

def myRangeSmart(i):
    n = 0
    while n < i:
       yield n
       n = n + 1
    return

for i in myRangeSmart(10):
    print i

Now upon each iteration a function on the generator called next() executes the function until it either reaches a 'yield' statement in which it stops and 'yields' the value or reaches the end of the function. In this case on the first call, next() executes up to the yield statement and yield 'n', on the next call it will execute the increment statement, jump back to the 'while', evaluate it, and if true, it will stop and yield 'n' again, it will continue that way until the while condition returns false and the generator jumps to the end of the function.

diff --color option was added to GNU diffutils 3.4 (2016-08-08)

This is the default diff implementation on most distros, which will soon be getting it.

Ubuntu 18.04 has diffutils 3.6 and therefore has it.

On 3.5 it looks like this:

Tested with:

diff --color -u \
  <(seq 6 | sed 's/$/ a/') \
  <(seq 8 | grep -Ev '^(2|3)$' | sed 's/$/ a/')

Apparently added in commit c0fa19fe92da71404f809aafb5f51cfd99b1bee2 (Mar 2015).

ydiff Git integration

ydiff integrates with Git without any configuration required.

From inside a git repository, instead of git diff, you can do just:

ydiff -s

and instead of git log:

ydiff -ls

For starters you aren't iterating over the result list properly, you are not using the index i at all. Try something like this:

List<Object> list = getHouseInfo();
for (int i=0; i<list.size; i++){
   System.out.println("Element "+i+list.get(i));
}

It looks like the query reutrns a List of Arrays of Objects, because Arrays are not proper objects that override toString you need to do a cast first and then use Arrays.toString().

 List<Object> list = getHouseInfo();
for (int i=0; i<list.size; i++){
   Object[] row = (Object[]) list.get(i);
   System.out.println("Element "+i+Arrays.toString(row));
}

Misconception Common misconception with column ordering is that, I should (or could) do the pushing and pulling on mobile devices, and that the desktop views should render in the natural order of the markup. This is wrong.

Reality Bootstrap is a mobile first framework. This means that the order of the columns in your HTML markup should represent the order in which you want them displayed on mobile devices. This mean that the pushing and pulling is done on the larger desktop views. not on mobile devices view..

Simple:

delete myObj.test.key1;

In Windows: use GetTickCount

//GetTickCount defintition
#include <windows.h>
int main()
{

    DWORD dw1 = GetTickCount();

    //Do something 

    DWORD dw2 = GetTickCount();

    cout<<"Time difference is "<<(dw2-dw1)<<" milliSeconds"<<endl;

The dollar sign is treated just like a normal letter or underscore (_). It has no special significance to the interpreter.

Unlike many similar languages, identifiers (such as functional and variable names) in Javascript can contain not only letters, numbers and underscores, but can also contain dollar signs. They are even allowed to start with a dollar sign, or consist only of a dollar sign and nothing else.

Thus, $ is a valid function or variable name in Javascript.

Why would you want a dollar sign in an identifier?

The syntax doesn't really enforce any particular usage of the dollar sign in an identifier, so it's up to you how you wish to use it. In the past, it has often been recommended to start an identifier with a dollar sign only in generated code - that is, code created not by hand but by a code generator.

In your example, however, this doesn't appear to be the case. It looks like someone just put a dollar sign at the start for fun - perhaps they were a PHP programmer who did it out of habit, or something. In PHP, all variable names must have a dollar sign in front of them.

There is another common meaning for a dollar sign in an interpreter nowadays: the jQuery object, whose name only consists of a single dollar sign ($). This is a convention borrowed from earlier Javascript frameworks like Prototype, and if jQuery is used with other such frameworks, there will be a name clash because they will both use the name $ (jQuery can be configured to use a different name for its global object). There is nothing special in Javascript that allows jQuery to use the single dollar sign as its object name; as mentioned above, it's simply just another valid identifier name.

One difference that's not at the language level but the popular implementation level: certain versions of gcc will remove unreferenced static inline functions from output by default, but will keep plain static functions even if unreferenced. I'm not sure which versions this applies to, but from a practical standpoint it means it may be a good idea to always use inline for static functions in headers.

You probably don't have access to one of the meta tables that SQL Developer 3 is querying. If I picked the right query, it runs the following SELECT statement:

select * from (
  SELECT o.OBJECT_NAME, o.OBJECT_ID ,'' short_name, decode(bitand(t.property, 32), 32, 'YES', 'NO') partitioned,
                decode(bitand(t.property, 64), 64, 'IOT',
               decode(bitand(t.property, 512), 512, 'IOT_OVERFLOW',
               decode(bitand(t.flags, 536870912), 536870912, 'IOT_MAPPING', null))) iot_type, 
         o.OWNER OBJECT_OWNER, o.CREATED, o.LAST_DDL_TIME, O.GENERATED, O.TEMPORARY, case when xt.obj# is null then 'N' else 'Y' end EXTERNAL
    FROM SYS.Dba_OBJECTS O ,sys.tab$ t, sys.external_tab$ xt
    WHERE O.OWNER = :SCHEMA
    and   o.object_id = t.obj#(+)
    and   o.object_id = xt.obj#(+)
    AND O.OBJECT_TYPE = 'TABLE' 
union all
SELECT OBJECT_NAME, OBJECT_ID , syn.SYNONYM_NAME short_NAME, decode(bitand(t.property, 32), 32, 'YES', 'NO') partitioned,
                decode(bitand(t.property, 64), 64, 'IOT',
               decode(bitand(t.property, 512), 512, 'IOT_OVERFLOW',
               decode(bitand(t.flags, 536870912), 536870912, 'IOT_MAPPING', null))) iot_type, 
       SYN.TABLE_OWNER OBJECT_OWNER, o.CREATED, o.LAST_DDL_TIME, O.GENERATED, O.TEMPORARY, case when xt.obj# is null then 'N' else 'Y' end EXTERNAL
              FROM SYS.Dba_OBJECTS O, sys.user_synonyms syn,sys.tab$ t, sys.external_tab$ xt
              WHERE  syn.table_owner = o.owner
              and    syn.TABLE_NAME = o.object_NAME
              and    o.object_id = t.obj#
              and   o.object_id = xt.obj#(+)
              and    o.object_type = 'TABLE'
              and    :INCLUDE_SYNS = 1
)
 where /**/object_name not in (select object_name from recyclebin)
                         AND not object_name like 'BIN$%'

Try to run this statement to get a full error messages indicating which table doesn't exists (which is equivalent to "is not visible due to missing access rights"). SQL Developer will ask for values for SCHEMA and INCLUDE_SYNS. Set SCHEMA to your username and INCLUDE_SYNS to 0.

SQL Developer 1.1 probably used a simpler query that worked with your access rights.

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

  for(var i = 0; i < BoardMessages.length;i++){
        (function(j){
            console.log("Loading message %d".green, j);
            htmlMessageboardString += MessageToHTMLString(BoardMessages[j]);
        })(i);
  }

That should work; however, you should never create a function in a loop. Therefore,

  for(var i = 0; i < BoardMessages.length;i++){
        composeMessage(BoardMessages[i]);
  }

  function composeMessage(message){
      console.log("Loading message %d".green, message);
      htmlMessageboardString += MessageToHTMLString(message);
  }

Other answers already on Stackoverflow:

• How do I install modules locally without root access...
• How can I use a new Perl module without install permissions?

From perlfaq8:

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuildpl_arg '--install_base /mydir/perl'
cpan> o conf commit

Thank you all for your great answers! Spent quite some time searching for a solution, and on my side I was making an elementary mistake: I was calling bodyParser.json() from within the function :

app.use(['/password'], async (req, res, next) => {_x000D_
  bodyParser.json()_x000D_
  /.../_x000D_
  next()_x000D_
})

I just needed to do app.use(['/password'], bodyParser.json()) and it worked...

Another built-in command that's long been installed in Windows by default dating back to 2003 is Certutil, which of course can be invoked from PowerShell, too.

CertUtil -hashfile file.foo MD5

(Caveat: MD5 should be in all caps for maximum robustness)

How about .delay() ?

http://api.jquery.com/delay/

$("#test").animate({"top":"-=80px"},1500)
          .delay(1000)
          .animate({"opacity":"0"},500);

If you are using SQL Server 2012 and above, you can use FORMATMESSAGE. eg.

DECLARE @s NVARCHAR(50) = 'World';
DECLARE @d INT = 123;
SELECT FORMATMESSAGE('Hello %s, %d', @s, @d)
-- RETURNS 'Hello World, 123'

More examples from MSDN: FORMATMESSAGE

SELECT FORMATMESSAGE('Signed int %i, %d %i, %d, %+i, %+d, %+i, %+d', 5, -5, 50, -50, -11, -11, 11, 11);
SELECT FORMATMESSAGE('Signed int with leading zero %020i', 5);
SELECT FORMATMESSAGE('Signed int with leading zero 0 %020i', -55);
SELECT FORMATMESSAGE('Unsigned int %u, %u', 50, -50);
SELECT FORMATMESSAGE('Unsigned octal %o, %o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal %x, %X, %X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Unsigned octal with prefix: %#o, %#o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal with prefix: %#x, %#X, %#X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Hello %s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %-20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');

NOTES:

• Undocumented in 2012
• Limited to 2044 characters
• To escape the % sign, you need to double it.
• If you are logging errors in extended events, calling FORMATMESSAGE comes up as a (harmless) error

Do you want something as simple like:

#include <unistd.h>
sleep(3);//sleeps for 3 second

If the dicts have identical sets of keys and you need all those prints for any value difference, there isn't much you can do; maybe something like:

diffkeys = [k for k in dict1 if dict1[k] != dict2[k]]
for k in diffkeys:
  print k, ':', dict1[k], '->', dict2[k]

pretty much equivalent to what you have, but you might get nicer presentation for example by sorting diffkeys before you loop on it.
