Proof of O(n)

The proof isn't fancy, and quite straightforward, I only proved the case for a full binary tree, the result can be generalized for a complete binary tree.

The problem is that if you redirect StandardOutput and/or StandardError the internal buffer can become full. Whatever order you use, there can be a problem:

• If you wait for the process to exit before reading StandardOutput the process can block trying to write to it, so the process never ends.
• If you read from StandardOutput using ReadToEnd then your process can block if the process never closes StandardOutput (for example if it never terminates, or if it is blocked writing to StandardError).

The solution is to use asynchronous reads to ensure that the buffer doesn't get full. To avoid any deadlocks and collect up all output from both StandardOutput and StandardError you can do this:

EDIT: See answers below for how avoid an ObjectDisposedException if the timeout occurs.

using (Process process = new Process())
{
    process.StartInfo.FileName = filename;
    process.StartInfo.Arguments = arguments;
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;

    StringBuilder output = new StringBuilder();
    StringBuilder error = new StringBuilder();

    using (AutoResetEvent outputWaitHandle = new AutoResetEvent(false))
    using (AutoResetEvent errorWaitHandle = new AutoResetEvent(false))
    {
        process.OutputDataReceived += (sender, e) => {
            if (e.Data == null)
            {
                outputWaitHandle.Set();
            }
            else
            {
                output.AppendLine(e.Data);
            }
        };
        process.ErrorDataReceived += (sender, e) =>
        {
            if (e.Data == null)
            {
                errorWaitHandle.Set();
            }
            else
            {
                error.AppendLine(e.Data);
            }
        };

        process.Start();

        process.BeginOutputReadLine();
        process.BeginErrorReadLine();

        if (process.WaitForExit(timeout) &&
            outputWaitHandle.WaitOne(timeout) &&
            errorWaitHandle.WaitOne(timeout))
        {
            // Process completed. Check process.ExitCode here.
        }
        else
        {
            // Timed out.
        }
    }
}

Version used to ensure that only one update in a time. JPA provider will check the version, if the expected version already increase then someone else already update the entity so an exception will be thrown.

So updating entity value would be more secure, more optimist.

If the value changes frequent, then you might consider not to use version field. For an example "an entity that has counter field, that will increased everytime a web page accessed"

To expand on what @JoshuaMaddox said, in the MDN Learning Area, under the "Introduction to HTML" section, the Document and website structure sub-section says (bold/emphasis is by me):

Header

Usually a big strip across the top with a big heading and/or logo. This is where the main common information about a website usually stays from one webpage to another.

Navigation bar

Links to the site's main sections; usually represented by menu buttons, links, or tabs. Like the header, this content usually remains consistent from one webpage to another — having an inconsistent navigation on your website will just lead to confused, frustrated users. Many web designers consider the navigation bar to be part of the header rather than a individual component, but that's not a requirement; in fact some also argue that having the two separate is better for accessibility, as screen readers can read the two features better if they are separate.

Theoretically, no, they are not unique. It's possible to generate an identical guid over and over. However, the chances of it happening are so low that you can assume they are unique.

I've read before that the chances are so low that you really should stress about something else--like your server spontaneously combusting or other bugs in your code. That is, assume it's unique and don't build in any code to "catch" duplicates--spend your time on something more likely to happen (i.e. anything else).

I made an attempt to describe the usefulness of GUIDs to my blog audience (non-technical family memebers). From there (via Wikipedia), the odds of generating a duplicate GUID:

• 1 in 2^128
• 1 in 340 undecillion (don’t worry, undecillion is not on the quiz)
• 1 in 3.4 × 10^38
• 1 in 340,000,000,000,000,000,000,000,000,000,000,000,000

df <- data.frame(x=rnorm(10), y=rnorm(10))
rownames(df) <-  letters[1:10]
df[c('a','b'),]

The problem must be with the value Model.Id which is null. You can confirm by assigning a value, e.g

@{         
     var blogPostId = 1;          
 }

If the error disappers, then u need to make sure that your model Id has a value before passing it to the view

table_ex

id default nextval('table_id_seq'::regclass),

camp1 varchar

camp2 varchar

INSERT INTO table_ex(camp1,camp2) VALUES ('xxx','123') RETURNING id 

Just send xml bytes directly:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
import requests

xml = """<?xml version='1.0' encoding='utf-8'?>
<a>?</a>"""
headers = {'Content-Type': 'application/xml'} # set what your server accepts
print requests.post('http://httpbin.org/post', data=xml, headers=headers).text

Output

{
  "origin": "x.x.x.x",
  "files": {},
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},
  "headers": {
    "Content-Length": "48",
    "Accept-Encoding": "identity, deflate, compress, gzip",
    "Connection": "keep-alive",
    "Accept": "*/*",
    "User-Agent": "python-requests/0.13.9 CPython/2.7.3 Linux/3.2.0-30-generic",
    "Host": "httpbin.org",
    "Content-Type": "application/xml"
  },
  "json": null,
  "data": "<?xml version='1.0' encoding='utf-8'?>\n<a>\u0431</a>"
}

The big difference is perfectly explained here.

Basically, lightweight tags are just pointers to specific commits. No further information is saved; on the other hand, annotated tags are regular objects, which have an author and a date and can be referred because they have their own SHA key.

If knowing who tagged what and when is relevant for you, then use annotated tags. If you just want to tag a specific point in your development, no matter who and when did that, then lightweight tags are good enough.

Normally you'd go for annotated tags, but it is really up to the Git master of the project.

Swift equivalent of @Tom's answer, although receiving RGBA Int value to support transparency:

func colorWithHex(aHex: UInt) -> UIColor
{
    return UIColor(red: CGFloat((aHex & 0xFF000000) >> 24) / 255,
        green: CGFloat((aHex & 0x00FF0000) >> 16) / 255,
        blue: CGFloat((aHex & 0x0000FF00) >> 8) / 255,
        alpha: CGFloat((aHex & 0x000000FF) >> 0) / 255)
}

//usage
var color = colorWithHex(0x7F00FFFF)

And if you want to be able to use it from string you could use strtoul:

var hexString = "0x7F00FFFF"

let num = strtoul(hexString, nil, 16)

var colorFromString = colorWithHex(num)

In your CustomAdapter class implement filterable.

 public class CustomAdapter extends BaseAdapter implements Filterable {

    private List<ItemsModel> itemsModelsl;
    private List<ItemsModel> itemsModelListFiltered;

    public CustomAdapter(List<ItemsModel> itemsModelsl, Context context) {
        this.itemsModelsl = itemsModelsl;
        this.itemsModelListFiltered = itemsModelsl;
        this.context = context;
    }

                startActivity(new Intent(MainActivity.this,ItemsPreviewActivity.class).putExtra("items",itemsModelListFiltered.get(position)));

            }
        });

        return view;
    }



    @Override

                    filterResults.values = itemsModelsl;

                }else{
                    List<ItemsModel> resultsModel = new ArrayList<>();
                    String searchStr = constraint.toString().toLowerCase();

                    for(ItemsModel itemsModel:itemsModelsl){
                        if(itemsModel.getName().contains(searchStr) || itemsModel.getEmail().contains(searchStr)){
                            resultsModel.add(itemsModel);

                        }
                         filterResults.count = resultsModel.size();
                            filterResults.values = resultsModel;
                    }


                }

                return filterResults;
            }

            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {

                itemsModelListFiltered = (List<ItemsModel>) results.values;
                notifyDataSetChanged();

            }
        };
        return filter;
    }
}

}

Usage

git clone <repository>

Clone the repository located at the <repository> onto the local machine. The original repository can be located on the local filesystem or on a remote machine accessible via HTTP or SSH.

git clone <repo> <directory>

Clone the repository located at <repository> into the folder called <directory> on the local machine.

Source: Setting up a repository

In my case I was making an connection through pgAdmin with ssh tunneling and set to host field ip address but it was necessary to set localhost

var indices = [];
var IDs = [0, 1, 2, 3, 4];

for(var i = 0, len = array.length; i < len; i++) {
    for(var j = 0; j < IDs.length; j++) {
        if(array[i].id == ID) indices.push(i);
    }
}

use default js match() function:

if( element.attr('class') !== undefined && element.attr('class').match(/class1|class2|class3|class4|class5/) ) {
  console.log("match");
}

to use variables in regexp, use this:

var reg = new RegExp(variable, 'g');
$(this).match(reg);

by the way, this is the fastest way: http://jsperf.com/hasclass-vs-is-stackoverflow/22

I think I observed a similar problem: some processes started, seemed to run successfully but never completed. The function waitFor() was waiting forever except if I killed the process in Task Manager.
However, everything worked well in cases the length of the command line was 127 characters or shorter. If long file names are inevitable you may want to use environmental variables, which may allow you keeping the command line string short. You can generate a batch file (using FileWriter) in which you set your environmental variables before calling the program you actually want to run. The content of such a batch could look like:

    set INPUTFILE="C:\Directory 0\Subdirectory 1\AnyFileName"
    set OUTPUTFILE="C:\Directory 2\Subdirectory 3\AnotherFileName"
    set MYPROG="C:\Directory 4\Subdirectory 5\ExecutableFileName.exe"
    %MYPROG% %INPUTFILE% %OUTPUTFILE%

Last step is running this batch file using Runtime.

This is pure JavaScript.

There is nothing special about $. It is just a character that may be used in variable names.

var $ = 1;
var $$ = 2;
alert($ + $$);

jQuery just assigns it's core function to a variable called $. The code you have assigns this to a local variable called self and the results of calling jQuery with this as an argument to a global variable called $self.

It's ugly, dirty, confusing, but $, self and $self are all different variables that happen to have similar names.

You cannot call PHP functions like clicking on a button from HTML. Because HTML is on the client side while PHP runs server side.

Either you need to use some Ajax or do it like as in the code snippet below.

<?php
    if ($_GET) {
        if (isset($_GET['insert'])) {
            insert();
        } elseif (isset($_GET['select'])) {
            select();
        }
    }

    function select()
    {
       echo "The select function is called.";
    }

    function insert()
    {
       echo "The insert function is called.";
    }
?>

You have to post your form data and then check for appropriate button that is clicked.

Follow the tutorial you listed above for setting up your key preferences in iterm2.

1. Create a new shorcut key
2. Choose "Send escape sequence" as the action
3. Then, to set cmd-left, in the text below that:
   • Enter [H for line start
     OR
   • Enter [F for line end

Get the children of the select box; loop through them; when you have found the one you want, set it as the selected option; return false to stop looping.

Introductory Note I'm inclined to post a few clarifications since some of the answers here were a little misleading (if not incorrect).

The answer is NO, you cannot simply pass a base64 encoded parameter within a URL query string since plus signs are converted to a SPACE inside the $_GET global array. In other words, if you sent test.php?myVar=stringwith+sign to

//test.php
print $_GET['myVar'];

the result would be:
stringwith sign

The easy way to solve this is to simply urlencode() your base64 string before adding it to the query string to escape the +, =, and / characters to %## codes. For instance, urlencode("stringwith+sign") returns stringwith%2Bsign

When you process the action, PHP takes care of decoding the query string automatically when it populates the $_GET global. For example, if I sent test.php?myVar=stringwith%2Bsign to

//test.php
print $_GET['myVar'];

the result would is:
stringwith+sign

You do not want to urldecode() the returned $_GET string as +'s will be converted to spaces.
In other words if I sent the same test.php?myVar=stringwith%2Bsign to

//test.php
$string = urldecode($_GET['myVar']);
print $string;

the result is an unexpected:
stringwith sign

It would be safe to rawurldecode() the input, however, it would be redundant and therefore unnecessary.

My answer:

set_headless(headless=True) is deprecated. 

https://seleniumhq.github.io/selenium/docs/api/py/webdriver_firefox/selenium.webdriver.firefox.options.html

options.headless = True

works for me

The most effective and simple solution I found:

<input
    type="number"
    name="phone"
    placeholder="Phone number"
    onKeyDown={e => /[\+\-\.\,]$/.test(e.key) && e.preventDefault()}
/>

Params contains the following three groups of parameters:

1. User supplied parameters
   • GET (http://domain.com/url?param1=value1&param2=value2 will set params[:param1] and params[:param2])
   • POST (e.g. JSON, XML will automatically be parsed and stored in params)
   • Note: By default, Rails duplicates the user supplied parameters and stores them in params[:user] if in UsersController, can be changed with wrap_parameters setting
2. Routing parameters
   • match '/user/:id' in routes.rb will set params[:id]
3. Default parameters
   • params[:controller] and params[:action] is always available and contains the current controller and action

To let SQL handle quote escape and everything else do this

BULK INSERT Test_CSV
FROM  'C:\MyCSV.csv' 
WITH (
 FORMAT='CSV'
 --FIRSTROW = 2,  --uncomment this if your CSV contains header, so start parsing at line 2
);

In regards to other answers, here is valuable info as well:

I keep seeing this in all answers: ROWTERMINATOR = '\n'
The \n means LF and it is Linux style EOL

In Windows the EOL is made of 2 chars CRLF so you need ROWTERMINATOR = '\r\n'

If the element only has one handler, then simply use jQuery unbind.

$("#element").unbind();

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

You will find Python's string literal documentation here:

http://docs.python.org/tutorial/introduction.html#strings

and here:

http://docs.python.org/reference/lexical_analysis.html#literals

The simplest example would be using the 'r' prefix:

ss = r'Hello\nWorld'
print(ss)
Hello\nWorld

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

You can use reduce to loop the array and get the not duplicate values. Also uses an aux object to get the count of added values.

var aux = {};_x000D_

I am making a scientific app that is already close to 45 thousand lines and I use asynchronous tasks in order to be able to interrupt long tasks, if so desired, with a certain click of the user.

Thus, there is a responsive user interface and sometimes a long task in parallel.

When the long task is over, I need to run a routine that manages the user interface.

So, at the end of an asynchronous task, I do a following action that involves the interface, which cannot be performed directly, otherwise it gives an error. So I use

this.runOnUiThread(Runnable { x(...)})   // Kotlin

Many times, this error occurs in some point of function x.

If function x was called outside a thread

              x(...)  // Kotlin

Android Studio would show a call stack with the error line and one easily could fix the problem in few minutes.

As my source code is tamed, and there is no serious structural problem (many answers above describe this kind of errors), the reason for this scary error message is more gross and less important.

It's just any fool mistake in this execution linked to a thread (like, for example, accessing a vector beyond the defined length), as in this schematic example:

           var i = 10                  // Kotlin
           ...
           var arr = Array(5){""}       
           var element = arr[i]       // 10 > 5, it's a index overflow

Regarding this stupid error, Android Studio unfortunately doesn't point to it.

I even consider it a bug, because Android Studio knows that there is an error, where it is located, but, for some unknown reason, it gets lost and gives a random message, totally disconnected from the problem, i.e, a weird message with no hint showing up.

The solution: Have a lot of patience to run step by step in the debugger until reaching the error line, which Android Studio refused to provide.

This has happened to me several times and I guess it's an extremely common mistake on Android projects. I had never before given this kind of error to me before I used threads.

Nobody is infallible and we are liable to make small mistakes. In this case, you cannot count on the direct help of Android Studio to discover where is your error!

Try one of these approaches:

Approach 1)

1- Choose project view

2- Copy your JAR file in app -> lib folder

3- Right click on your JAR file and choose add as library

4- Check it in build.gradle

Approach 2)

1- File -> New -> New Module

2- Import .JAR/.AAR Package

3- Browse your JAR File

4- Finish

5- File -> Project Structure -> Dependencies

6- You should click on + button and then click on Module Dependency

7- You will see your library here

8- choose your library and click ok

9- Then, you will see that your library is added.

For first two approaches, you need a JAR file. You can search http://search.maven.org/ to find JAR files that are related to Android. For example, this is the search result for jdom in this link

Approach 3) Android is using http://jcenter.bintray.com/ as remote library. For example, this is the search result for jdom in the link.

To add a library in this approach, please follow these steps:

1- File -> Project Structure -> Dependencies

2- Click on + button and choose library dependency

3- find your library and select it, then click OK.

I hope it helps.

You could do that:

1. By looping through all the KeyValuePair<TKey, TValue>'s in the dictionary (which will be a sizable performance hit if you have a number of entries in the dictionary)
2. Use two dictionaries, one for value-to-key mapping and one for key-to-value mapping (which would take up twice as much space in memory).

Use Method 1 if performance is not a consideration, use Method 2 if memory is not a consideration.

Also, all keys must be unique, but the values are not required to be unique. You may have more than one key with the specified value.

Is there any reason you can't reverse the key-value relationship?

A cursor is a SELECTed window on an Oracle table, this means a group of records present in an Oracle table, and satisfying certain conditions. A cursor can SELECT all the content of a table, too. With a cursor you can manipulate Oracle columns, aliasing them in the result. An example of implicit cursor is the following:

BEGIN
   DECLARE
      CURSOR C1
      IS
         SELECT DROPPED_CALLS FROM ALARM_UMTS;

      C1_REC   C1%ROWTYPE;
   BEGIN
      FOR C1_REC IN C1
      LOOP
         DBMS_OUTPUT.PUT_LINE ('DROPPED CALLS: ' || C1_REC.DROPPED_CALLS);
      END LOOP;
   END;
END;
/

With FOR ... LOOP... END LOOP you open and close the cursor authomatically, when the records of the cursor have been all analyzed.

An example of explicit cursor is the following:

BEGIN
   DECLARE
      CURSOR C1
      IS
         SELECT DROPPED_CALLS FROM ALARM_UMTS;

      C1_REC   C1%ROWTYPE;
   BEGIN
      OPEN c1;

      LOOP
         FETCH c1 INTO c1_rec;

         EXIT WHEN c1%NOTFOUND;

         DBMS_OUTPUT.PUT_LINE ('DROPPED CALLS: ' || C1_REC.DROPPED_CALLS);
      END LOOP;

      CLOSE c1;
   END;
END;
/

In the explicit cursor you open and close the cursor in an explicit way, checking the presence of records and stating an exit condition.

Answer has been updated

count is a Collection method. The query builder returns an array. So in order to get the count, you would just count it like you normally would with an array:

$wordCount = count($wordlist);

If you have a wordlist model, then you can use Eloquent to get a Collection and then use the Collection's count method. Example:

$wordlist = Wordlist::where('id', '<=', $correctedComparisons)->get();
$wordCount = $wordlist->count();

There is/was a discussion on having the query builder return a collection here: https://github.com/laravel/framework/issues/10478

However as of now, the query builder always returns an array.

Edit: As linked above, the query builder now returns a collection (not an array). As a result, what JP Foster was trying to do initially will work:

$wordlist = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)
            ->get();
$wordCount = $wordlist->count();

However, as indicated by Leon in the comments, if all you want is the count, then querying for it directly is much faster than fetching an entire collection and then getting the count. In other words, you can do this:

// Query builder
$wordCount = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)
            ->count();

// Eloquent
$wordCount = Wordlist::where('id', '<=', $correctedComparisons)->count();

Your code is fine. There's no problem with returning Strings in this manner.

In Java, a String is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String around without worrying that it would disapper on you, or that someone somewhere would modify it.

If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:

public String time_to_string(long t) // time in milliseconds
{
    if (t < 0)
    {
        return "-";
    }
    else
    {
        int secs = (int)(t/1000);
        int mins = secs/60;
        secs = secs - (mins * 60);
        return String.format("%d:%02d", mins, secs);
    }
}

As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans and have replaced the mix of string concatenation and String.format() with a single call to String.format().

The obvious thing to do is just convert the search term to lowercase:

if (in_array(strtolower($word), $array)) { 
  ...

of course if there are uppercase letters in the array you'll need to do this first:

$search_array = array_map('strtolower', $array);

and search that. There's no point in doing strtolower on the whole array with every search.

Searching arrays however is linear. If you have a large array or you're going to do this a lot, it would be better to put the search terms in key of the array as this will be much faster access:

$search_array = array_combine(array_map('strtolower', $a), $a);

then

if ($search_array[strtolower($word)]) { 
  ...

The only issue here is that array keys must be unique so if you have a collision (eg "One" and "one") you will lose all but one.

Actually you can only style few CSS properties on :modified option elements. color does not work, background-color either, but you can set a background-image.

You can couple this with gradients to do the trick.

option:hover,_x000D_
option:focus,_x000D_
option:active,_x000D_
option:checked {_x000D_
  background: linear-gradient(#5A2569, #5A2569);_x000D_
}

<select>_x000D_
  <option>A</option>_x000D_
  <option>B</option>_x000D_
  <option>C</option>_x000D_
</select>

Works on gecko/webkit.

If you want just the summary of the exception use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

If you want to see the whole stack trace (usually better for debugging) use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }

Another method I sometime use is:

    private DoSomthing(int arg1, int arg2, out string errorMessage)
    {
         int result ;
        errorMessage = String.Empty;
        try 
        {           
            //do stuff
            int result = 42;
        }
        catch (Exception ex)
        {

            errorMessage = ex.Message;//OR ex.ToString(); OR Free text OR an custom object
            result = -1;
        }
        return result;
    }

And In your form you will have something like:

    string ErrorMessage;
    int result = DoSomthing(1, 2, out ErrorMessage);
    if (!String.IsNullOrEmpty(ErrorMessage))
    {
        MessageBox.Show(ErrorMessage);
    }

More complete sample from here and here.

Or you can check out my layout sample. p.s no need to put API key in the map view.

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <com.google.android.gms.maps.MapView
            android:id="@+id/map_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="2"
            />

    <ListView android:id="@+id/nearby_lv"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:background="@color/white"
              android:layout_weight="1"
            />

</LinearLayout>

To do this, you can set a callback function for the animate command which will execute after the scroll animation has finished.

For example:

var body = $("html, body");
body.stop().animate({scrollTop:0}, 500, 'swing', function() { 
   alert("Finished animating");
});

Where that alert code is, you can execute more javascript to add in further animation.

Also, the 'swing' is there to set the easing. Check out http://api.jquery.com/animate/ for more info.

i solve it

change 22.0.0 to 21.0.3

dependencies {

 compile fileTree(dir: 'libs', include: ['*.jar'])

//compile 'com.android.support:appcompat-v7:22.0.0'

compile 'com.android.support:appcompat-v7:21.0.3'  }

maybe i have download the com.android.support:appcompat-v7:21.0.3 but have not got the compile 'com.android.support:appcompat-v7:22.0.0'

when i use SDK Manager update my support library and support repository , the problem dismissed.

So there is two ways to pass values from fragment/activity to dialog fragment:-

1. Create dialog fragment object with make setter method and pass value/argument.

2. Pass value/argument through bundle.

Method 1:

// Fragment or Activity 
@Override
public void onClick(View v) {
     DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
     dialog.setValue(header, body);
     dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");         
}


//  your dialog fragment
public class MyDialogFragment extends DialogFragment {
    String header; 
    String body;
    public void setValue(String header, String body) {   
          this.header = header;
          this.body = body;
    }
    // use above variable into your dialog fragment
}

Note:- This is not best way to do

Method 2:

// Fragment or Activity 
@Override
public void onClick(View v) {
     DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
     
     Bundle bundle = new Bundle();
     bundle.putString("header", "Header");
     bundle.putString("body", "Body");  
     dialog.setArguments(bundle);
     dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");         
}


//  your dialog fragment
public class MyDialogFragment extends DialogFragment {
    String header; 
    String body;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
             header = getArguments().getString("header","");
             body = getArguments().getString("body","");
        }
    }
    // use above variable into your dialog fragment
}

Note:- This is the best way to do.

If you need the allocation to the columns only once the answer is the "Text to Columns" functionality in MS Excel.

HTH

To count items after some number of items (offset), $qb->setFirstResults() cannot be applied in this case, as it works not as a condition of query, but as an offset of query result for a range of items selected (i. e. setFirstResult cannot be used togather with COUNT at all). So to count items, which are left I simply did the following:

   //in repository class:
   $count = $qb->select('count(p.id)')
      ->from('Products', 'p')
      ->getQuery()
      ->getSingleScalarResult();

    return $count;

    //in controller class:
    $count = $this->em->getRepository('RepositoryBundle')->...

    return $count-$offset;

Anybody knows more clean way to do it?

I kept getting the same error inspite of making the variable static. Solution: Clean Build, Clean Derived Data, Restart Xcode. Or shortcut Cmd + Shift+Alt+K

UserNotificationCenterWrapper.delegate = self

public static var delegate: UNUserNotificationCenterDelegate? {
        get {
            return UNUserNotificationCenter.current().delegate
        }
        set {
            UNUserNotificationCenter.current().delegate = newValue
        }
    }

Change SUM(billableDuration) AS NumSecondsDelivered to

sum(cast(billableDuration as bigint)) or

sum(cast(billableDuration as numeric(12, 0))) according to your need.

The resultant type of of Sum expression is the same as the data type used. It throws error at time of overflow. So casting the column to larger capacity data type and then using Sum operation works fine.

This will work for international numbers;

C#:

@"^((\+\d{1,3}(-| )?\(?\d\)?(-| )?\d{1,5})|(\(?\d{2,6}\)?))(-| )?(\d{3,4})(-| )?(\d{4})(( x| ext)\d{1,5}){0,1}$"

JS:

/^((\+\d{1,3}(-| )?\(?\d\)?(-| )?\d{1,5})|(\(?\d{2,6}\)?))(-| )?(\d{3,4})(-| )?(\d{4})(( x| ext)\d{1,5}){0,1}$/

Type in:

man lsof

Then look for -w, -n, and -i

-i: internet stuff -n: makes it faster -w: toggles warnings

There are WAY more details on the man pages

Just add this namespace,

using System.Linq;

Below is a simple way to convert dataframe column into numpy array.

df = pd.DataFrame(somedict) 
ytrain = df['label']
ytrain_numpy = np.array([x for x in ytrain['label']])

ytrain_numpy is a numpy array.

I tried with to.numpy() but it gave me the below error: TypeError: no supported conversion for types: (dtype('O'),) while doing Binary Relevance classfication using Linear SVC. to.numpy() was converting the dataFrame into numpy array but the inner element's data type was list because of which the above error was observed.

First, fetch the latest commits from the remote repo. This will not affect your local branch.

git fetch origin

Then checkout the remote tracking branch and do a git log to see the commits

git checkout origin/master
git log

Grab the commit hash of the commit you want to merge up to (or just the first ~5 chars of it) and merge that commit into master

git checkout master
git merge <commit hash>

If you have a Style component that you can require from your Component, then you could have something like this at the top of the file:

const Dimensions = require('Dimensions');

const window = Dimensions.get('window');

And then you could provide fulscreen: {width: window.width, height: window.height}, in your Style component. Hope this helps

According to SharkAlley answer it works with nginx too.

I was search for a solution to get data by jQuery from a server behind nginx and restricted by Base Auth. This works for me:

server {
    server_name example.com;

    location / {
        if ($request_method = OPTIONS ) {
            add_header Access-Control-Allow-Origin "*";
            add_header Access-Control-Allow-Methods "GET, OPTIONS";
            add_header Access-Control-Allow-Headers "Authorization";

            # Not necessary
            #            add_header Access-Control-Allow-Credentials "true";
            #            add_header Content-Length 0;
            #            add_header Content-Type text/plain;

            return 200;
        }

        auth_basic "Restricted";
        auth_basic_user_file /var/.htpasswd;

        proxy_pass http://127.0.0.1:8100;
    }
}

And the JavaScript code is:

var auth = btoa('username:password');
$.ajax({
    type: 'GET',
    url: 'http://example.com',
    headers: {
        "Authorization": "Basic " + auth
    },
    success : function(data) {
    },
});

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

var arr = [];             //new storage
str = str.split(' ');     //split by spaces
arr.push(str.shift());    //add the number
arr.push(str.join(' '));  //and the rest of the string

//arr is now:
["72","tocirah sneab"];

but i still think there is a faster way though.

You can still get Fatal error: Call to undefined function imagecreatefromjpeg() even if GD is installed.

The solution is to install/enable jped lib:

On Ubuntu:

    apt-get install libjpeg-dev
    apt-get install libfreetype6-dev

On CentOS:

    yum install libjpeg-devel
    yum install freetype-devel

If compiling from source add --with-jpeg-dir --with-freetype-dir or --with-jpeg-dir=/usr --with-freetype-dir=/usr.

For more details check https://www.tectut.com/2015/10/solved-call-to-undefined-function-imagecreatefromjpeg/

git read-tree -um @ $commit_to_revert_to

will do it. It's "git checkout" but without updating HEAD.

You can achieve the same effect with

git checkout $commit_to_revert_to
git reset --soft @{1}

if you prefer stringing convenience commands together.

These leave you with your worktree and index in the desired state, you can just git commit to finish.

"user.dir" is the current working directory, not the home directory It is all described here.

http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

Also, by using \\ instead of File.separator, you will lose portability with *nix system which uses / for file separator.

From Eclipsepedia on how to set a conditional breakpoint:

First, set a breakpoint at a given location. Then, use the context menu on the breakpoint in the left editor margin or in the Breakpoints view in the Debug perspective, and select the breakpoint’s properties. In the dialog box, check Enable Condition, and enter an arbitrary Java condition, such as list.size()==0. Now, each time the breakpoint is reached, the expression is evaluated in the context of the breakpoint execution, and the breakpoint is either ignored or honored, depending on the outcome of the expression.

Conditions can also be expressed in terms of other breakpoint attributes, such as hit count.

Shift-Tab works for me to view the dcoumentation

you can use raw literals. Example

s:=`stack
overflow`

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

There's also the pygame.freetype module which is more modern, works with more fonts and offers additional functionality.

Create a font object with pygame.freetype.SysFont() or pygame.freetype.Font if the font is inside of your game directory.

You can render the text either with the render method similarly to the old pygame.font.Font.render or directly onto the target surface with render_to.

import pygame
import pygame.freetype  # Import the freetype module.


pygame.init()
screen = pygame.display.set_mode((800, 600))
GAME_FONT = pygame.freetype.Font("your_font.ttf", 24)
running =  True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill((255,255,255))
    # You can use `render` and then blit the text surface ...
    text_surface, rect = GAME_FONT.render("Hello World!", (0, 0, 0))
    screen.blit(text_surface, (40, 250))
    # or just `render_to` the target surface.
    GAME_FONT.render_to(screen, (40, 350), "Hello World!", (0, 0, 0))

    pygame.display.flip()

pygame.quit()

As far as I know, there is only one small difference is when you are trying to insert value which is out of range.

In examples I'll use 401421228216, which is 101110101110110100100011101100010111000 (length 39 characters)

• If you have INT(20) for system this means allocate in memory minimum 20 bits. But if you'll insert value that bigger than 2^20, it will be stored successfully, only if it's less then INT(32) -> 2147483647 (or 2 * INT(32) -> 4294967295 for UNSIGNED)

Example:

mysql> describe `test`;
+-------+------------------+------+-----+---------+-------+
| Field | Type             | Null | Key | Default | Extra |
+-------+------------------+------+-----+---------+-------+
| id    | int(20) unsigned | YES  |     | NULL    |       |
+-------+------------------+------+-----+---------+-------+
1 row in set (0,00 sec)

mysql> INSERT INTO `test` (`id`) VALUES (401421228216);
ERROR 1264 (22003): Out of range value for column 'id' at row 1

mysql> SET sql_mode = '';
Query OK, 0 rows affected, 1 warning (0,00 sec)

mysql> INSERT INTO `test` (`id`) VALUES (401421228216);

1 row in set (0,00 sec)

• If you have BIGINT(20) for system this means allocate in memory minimum 20 bits. But if you'll insert value that bigger than 2^20, it will be stored successfully, if it's less then BIGINT(64) -> 9223372036854775807 (or 2 * BIGINT(64) -> 18446744073709551615 for UNSIGNED)

Example:

In jQuery 3 and perhaps earlier versions, the following simpler config also works for individual requests:

$.ajax(
        'https://foo.bar.com,
        {
            dataType: 'json',
            xhrFields: {
                withCredentials: true
            },
            success: successFunc
        }
    );

The full error I was getting in Firefox Dev Tools -> Network tab (in the Security tab for an individual request) was:

An error occurred during a connection to foo.bar.com.SSL peer was unable to negotiate an acceptable set of security parameters.Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

Kenny is right, just want to clear some things out.

1. Create the file border.xml and put it in the folder res/drawable/

2. add the code

   <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
      <stroke android:width="4dp" android:color="#FF00FF00" /> 
      <solid android:color="#ffffff" /> 
      <padding android:left="7dp" android:top="7dp" 
           android:right="7dp" android:bottom="0dp" /> 
      <corners android:radius="4dp" /> 
   </shape>
   

3. set back ground like android:background="@drawable/border" wherever you want the border

Mine first didn't work cause i put the border.xml in the wrong folder!

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{
    typedef int VLA[m][m];     // valid: block scope typedef VLA
    struct tag {
        int (*y)[n];           // invalid: y not ordinary identifier
        int z[n];              // invalid: z not ordinary identifier
    };
    int D[m];                  // valid: auto VLA
    static int E[m];           // invalid: static block scope VLA
    extern int F[m];           // invalid: F has linkage and is VLA
    int (*s)[m];               // valid: auto pointer to VLA
    extern int (*r)[m];        // invalid: r has linkage and points to VLA
    static int (*q)[m] = &B;   // valid: q is a static block pointer to VLA
}

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c

This is because the inline style display:block is overwriting your CSS. You'll need to either remove this inline style or use:

#tfl {
  display: none !important;
}

This overrides inline styles. Note that using !important is generally not recommended unless it's a last resort.

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Here's some documentation on how to use Jconsole.

With netcat and awk you can handle the server response manually:

if netcat 127.0.0.1 8080 <<EOF | awk 'NR==1{if ($2 == "500") exit 0; exit 1;}'; then
GET / HTTP/1.1
Host: www.example.com

EOF

    apache2ctl restart;
fi

Try This, It's working for me .

Custom Array adapter to hide the last item of the spinner

 import android.content.Context
 import android.widget.ArrayAdapter
 import android.widget.Spinner

 class HintAdapter<T>(context: Context, resource: Int, objects: Array<T>) :
    ArrayAdapter<T>(context, resource, objects) {

    override fun getCount(): Int {
        val count = super.getCount()
        // The last item will be the hint.
        return if (count > 0) count - 1 else count
    }
}

Spinner Extension function to set hint on spinner

fun Spinner.addHintWithArray(context: Context, stringArrayResId: Int) {
    val hintAdapter =
        HintAdapter<String>(
            context,
            android.R.layout.simple_spinner_dropdown_item,
            context.resources.getStringArray(stringArrayResId)
        )
    hintAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    adapter = hintAdapter
    setSelection(hintAdapter.count)
}

How to use: add the extension by passing context and array on Spinner

spinnerMonth.addHintWithArray(context, R.array.months)

Note: The hint should be the last item of your string array

<string-array name="months">
    <item>Jan</item>
    <item>Feb</item>
    <item>Mar</item>
    <item>Apr</item>
    <item>May</item>
    <item>Months</item>
</string-array>

Thanks for the input. Tried the stuff that has been mentioned here and these are the 2 I got to work:

(
select 'OK', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
AND TimeStamp>'2009-02-12 18:00:00'
AND (BoolField05=1)
)
UNION
(
select 'DEL', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
AND TimeStamp>'2009-02-12 18:00:00'
AND NOT (BoolField05=1)
)

AND

select 
    case
        when
            (BoolField05=1)
    then 'OK'
    else 'DEL'
        end,
        *
from WorkItems t1
Where
            exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
            AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
            AND TimeStamp>'2009-02-12 18:00:00'

Which would be the most efficient of these (edit: the second as it only scans the table once), and is it possible to make it even more efficient? (The BoolField=1) is really a variable (dyn sql) that can contain any where statement on the table.

I am running on MS SQL 2005. Tried Quassnoi examples but did not work as expected.

You can use a third-party library like base64-img or base64-to-image.

1. base64-img

const base64Img = require('base64-img');

const data = 'data:image/png;base64,...';
const destpath = 'dir/to/save/image';
const filename = 'some-filename';

base64Img.img(data, destpath, filename, (err, filepath) => {}); // Asynchronous using

const filepath = base64Img.imgSync(data, destpath, filename); // Synchronous using

2. base64-to-image

const base64ToImage = require('base64-to-image');

const base64Str = 'data:image/png;base64,...';
const path = 'dir/to/save/image/'; // Add trailing slash
const optionalObj = { fileName: 'some-filename', type: 'png' };

const { imageType, fileName } = base64ToImage(base64Str, path, optionalObj); // Only synchronous using

Update Nov -2017

1) Go to Mongo DB download center https://www.mongodb.com/download-center#community and pick a flavor of MongoDB you want to install. You can pick from

• MongoDB Atlas - MongoDB database in the cloud
• Communiy Server - MongoDb for windows (with and without SSL),iOS, Linux
• OpManger- Mongo Db for Data Center
• Compass - UI tool for MongoDB

To know your OS version run this command in cmd prompt

wmic os get caption

To know your CPU architecture(32 or 64 bit) run this command in cmd prompt

wmic os get osarchitecture

I am using Community version (150MBs- GNU license)

2) Click on MSI and go through installation Process. Exe will install MongoDb and SSL required by the DB.

Mongo DB should be installed on your C drive

C:\Program Files\MongoDB

MongoDB is self-contained, it means and does not have any other system dependencies. If you are low on disk in C drive then you can run MongoDB from any folder you choose.

You can now run mongodb.exe from bin folder. If you get Visual C++ error for missing dlls then download Visual C++ Redistributable from

https://www.microsoft.com/en-in/download/details.aspx?id=48145

After installation, try to rerun mongo.exe.

Since some developers are coming to this page in search of a solution which not only eliminates duplicate consecutive non-whitespace substrings, but triplicates and beyond, I'll show the adapted pattern.

Pattern: /(\b\S+)(?:\s+\1\b)+/ (Pattern Demo)
Replace: $1 (replaces the fullstring match with capture group #1)

This pattern greedily matches a "whole" non-whitespace substring, then requires one or more copies of the matched substring which may be delimited by one or more whitespace characters (space, tab, newline, etc).

Specifically:

• \b (word boundary) characters are vital to ensure partial words are not matched.
• The second parenthetical is a non-capturing group, because this variable width substring does not need to be captured -- only matched/absorbed.
• the + (one or more quantifier) on the non-capturing group is more appropriate than * because * will "bother" the regex engine to capture and replace singleton occurrences -- this is wasteful pattern design.

*note if you are dealing with sentences or input strings with punctuation, then the pattern will need to be further refined.

1. Upto my knowledge, Heap space is occupied by instance variables only. If this is correct, then why this error occurred after running fine for sometime as space for instance variables are alloted at the time of object creation.

That means you are creating more objects in your application over a period of time continuously. New objects will be stored in heap memory and that's the reason for growth in heap memory.

Heap not only contains instance variables. It will store all non-primitive data types ( Objects). These objects life time may be short (method block) or long (till the object is referenced in your application)

2. Is there any way to increase the heap space?

Yes. Have a look at this oracle article for more details.

There are two parameters for setting the heap size:

-Xms:, which sets the initial and minimum heap size

-Xmx:, which sets the maximum heap size

3. What changes should I made to my program so that It will grab less heap space?

It depends on your application.

1. Set the maximum heap memory as per your application requirement

2. Don't cause memory leaks in your application

3. If you find memory leaks in your application, find the root cause with help of profiling tools like MAT, Visual VM , jconsole etc. Once you find the root cause, fix the leaks.

Important notes from oracle article

Cause: The detail message Java heap space indicates object could not be allocated in the Java heap. This error does not necessarily imply a memory leak.

Possible reasons:

1. Improper configuration ( not allocating sufficiant memory)
2. Application is unintentionally holding references to objects and this prevents the objects from being garbage collected
3. Applications that make excessive use of finalizers. If a class has a finalize method, then objects of that type do not have their space reclaimed at garbage collection time. If the finalizer thread cannot keep up, with the finalization queue, then the Java heap could fill up and this type of OutOfMemoryError exception would be thrown.

On a different note, use better Garbage collection algorithms ( CMS or G1GC)

Have a look at this question for understanding G1GC

I would suggest you check out the various tutorials that are coming out lately. My current fav is:

You can check out this post on SuperUser.

Word starts page numbering over for each new section by default.

I do it slightly differently than the post above that goes through the ribbon menus, but in both methods you have to go through the document to each section's beginning.

My method:

• open up the footer (or header if that's where your page number is)
• drag-select the page number
• right-click on it
• hit Format Page Numbers
• click on the Continue from Previous Section radio button under Page numbering

I find this right-click method to be a little faster. Also, usually if I insert the page numbers first before I start making any new sections, this problem doesn't happen in the first place.

I would use the following approach:

=SUBSTITUTE(LEFT(A2,LEN(A2)-X),"_","-")

where X denotes the length of things you're not after. And, for X I'd use

(ISERROR(FIND("_S",A2,1))*2)+
(ISERROR(FIND("_40K",A2,1))*4)+
(ISERROR(FIND("_60K",A2,1))*4)+
(ISERROR(FIND("_AB",A2,1))*3)+
(ISERROR(FIND("_CD",A2,1))*3)+
(ISERROR(FIND("_EF",A2,1))*3)

The above ISERROR(FIND("X",.,.))*x will return 0 if X is not found and x (the length of X) if it is found. So technically you're trimming A2 from the right with possible matches.

The advantage of this approach above the other mentioned is that it's more apparent what substitution (or removal) is taking place, since the "substitution" is not nested.

As "there are tens of thousands of cells in the page" binding the click-event to every single cell will cause a terrible performance problem. There's a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:

$('body').click(function(e){
       var Elem = e.target;
       if (Elem.nodeName=='td'){
           //.... your business goes here....
           // remember to replace $(this) with $(Elem)
       }
})

This method will not only do your task with native "td" tag but also with later appended "td". I think you'll be interested in this article about event binding & delegate

Or you can simply use the ".on()" method of jQuery with the same effect:

$('body').on('click', 'td', function(){
        ...
});

Add:

mysql_query("SET NAMES UTF8");

below:

mysql_select_db(/*your_database_name*/);

Lodash https://lodash.com/docs#isInteger (since 4.0.0) has function to check if variable is an integer:

_.isInteger(3);
// ? true

_.isInteger(Number.MIN_VALUE);
// ? false

_.isInteger(Infinity);
// ? false

_.isInteger('3');
// ? false

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

This will work for any date in the format YYYY-MM-DD HH:mm:ss

const moment=require("moment");
let startDate=moment("2020-09-16 08:39:27");
const endDate=moment();


const duration=moment.duration(endDate.diff(startDate))
console.log(duration.asSeconds());
 console.log(duration.asHours());

This is the simplest way, which I used a lot. It works for any one-character delimiter.

#include<bits/stdc++.h>
using namespace std;

int main() {
   string str;

   cin >> str;
   int temp;
   vector<int> result;
   char ch;
   stringstream ss(str);

   do
   {
       ss>>temp;
       result.push_back(temp);
   }while(ss>>ch);

   for(int i=0 ; i < result.size() ; i++)
       cout<<result[i]<<endl;

   return 0;
}

yield break is just a way of saying return for the last time and don't return any value

e.g

// returns 1,2,3,4,5
IEnumerable<int> CountToFive()
{
    yield return 1;
    yield return 2;
    yield return 3;
    yield return 4;
    yield return 5;
    yield break;
    yield return 6;
    yield return 7;
    yield return 8;
    yield return 9;
 }

@JustGoscha's answer is spot on, but that's a lot to type when I want access, so I added this to the bottom of my app.js. Then all I have to type is x = getSrv('$http') to get the http service.

// @if DEBUG
function getSrv(name, element) {
    element = element || '*[ng-app]';
    return angular.element(element).injector().get(name);
}
// @endif

It adds it to the global scope but only in debug mode. I put it inside the @if DEBUG so that I don't end up with it in the production code. I use this method to remove debug code from prouduction builds.

Use this:

$sheet->getStyle('A1:'.$sheet->getHighestColumn().'1')->getFont()->setBold(true);

Fastest solution

let a = new Array(n); for (let i=0; i<n; ++i) a[i] = 0;

Shortest (handy) solution (3x slower for small arrays, slightly slower for big (slowest on Firefox))

Array(n).fill(0)

Details

Today 2020.06.09 I perform tests on macOS High Sierra 10.13.6 on browsers Chrome 83.0, Firefox 77.0, and Safari 13.1. I test chosen solutions for two test cases

• small array - with 10 elements - you can perform test HERE
• big arrays - with 1M elements - you can perform test HERE

Conclusions

• solution based on new Array(n)+for (N) is fastest solution for small arrays and big arrays (except Chrome but still very fast there) and it is recommended as fast cross-browser solution
• solution based on new Float32Array(n) (I) returns non typical array (e.g. you cannot call push(..) on it) so I not compare its results with other solutions - however this solution is about 10-20x faster than other solutions for big arrays on all browsers
• solutions based on for (L,M,N,O) are fast for small arrays
• solutions based on fill (B,C) are fast on Chrome and Safari but surprisingly slowest on Firefox for big arrays. They are medium fast for small arrays
• solution based on Array.apply (P) throws error for big arrays

4. On that page, find the 'Scopes' section. Click 'Add an OAuth Scope' and add 'channels:history' and 'chat:write'. (see scopes)
5. At the top of the page, Click 'Install App to Workspace'. Confirm, and on page reload, copy the OAuth Access Token.

Find the channel ID

Also, the channel ID can be seen in the browser URL when you open slack in the browser. e.g.

https://mycompany.slack.com/messages/MY_CHANNEL_ID/

or

https://app.slack.com/client/WORKSPACE_ID/MY_CHANNEL_ID

I was having this issue in a WebForms application, the error clearly says that A default document is not configured and it was true in my case, the default document was not configured. What worked for me is that I clicked on my site and on the middle pane in iis there is an option named Default Document. In the Default Document you have to check if the default page of the application exists or not.

The default page of my application was index.aspx and it wasnt present on iis Default Document window. So I made a new entry of index.aspx and it started working.

Hi easiest way to do this is to convert this IEnumerable into a Queryable

If it is a queryable, then performing queries becomes easy.

Please check this code:

var result = (from s in _ctx.ScannedDatas.AsQueryable()
                              where s.Data == scanData
                              select s.Id).FirstOrDefault();
                return "Match Found";

Make sure you include System.Linq. This way your error will be resolved.

Here I am posting you the some code example which record good quality of sound using AudioRecord API.

Happy Coding !!

You need to write a selector which selects the correct <input> first. Ideally you use the element's ID $('#element_id'), failing that the ID of it's container $('#container_id input'), or the element's class $('input.class_name').

Your element has none of these and no context, so it's hard to tell you how to select it.

Once you have figured out the proper selector, you'd use the attr method to access the element's attributes. To get the name, you'd use $(selector).attr('name') which would return (in your example) 'xxxxx'.

My solution.

var map;
var infowindow = new google.maps.InfoWindow();
...
function createMarker(...) {
var marker = new google.maps.Marker({
     ...,
     descrip: infowindowHtmlContent  
});
google.maps.event.addListener(marker, 'click', function() {
    infowindow.setOptions({
        content: this.descrip,
        maxWidth:300
    });
    infowindow.open(map, marker);
});

This method is easier and safer

var lOrders = new List<string>();

bool insertOrderNew = lOrders.Find(r => r == "1234") == null ? true : false

Save the following into a file with ".reg" suffix:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe]
"CodePage"=dword:0000fde9

Double click this file, and regedit will import it.

It basically sets the key HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe\CodePage to 0xfde9 (65001 in decimal system).

One another way is to separate out the APIs, services, and entities into different packages.

This is not Bootstrap Standard to give col-md-1.5 and you can not edit bootstrap.min.css because is not right way. you can create like this http://www.bootply.com/125259

yes on your aspx page include a script tag with runat=server

<script language="c#" runat="server">

public void Page_Load(object sender, EventArgs e)
{
  // some load code
}
</script>

You can also use classic ASP Syntax

<% if (this.MyTextBox.Visible) { %>
<span>Only show when myTextBox is visible</span>
<% } %>

I've found this to work the best across all browsers and devices (PC, tables & mobile).

<script type="text/javascript">

                          if(iFrameID) {
                                // here you can make the height, I delete it first, then I make it again
                                iFrameID.height = "";
                                iFrameID.height = iFrameID.contentWindow.document.body.scrollHeight + "px";
                          }   
                      }
                    </script>

I came across this question while trying to answer the same question. McCrohan's approach with the classes array & join is solid.

Through my experience, I have been working with a lot of legacy ruby code that is being converted to React and as we build the component(s) up I find myself reaching out for both existing css classes and inline styles.

example snippet inside a component:

// if failed, progress bar is red, otherwise green 
<div
    className={`progress-bar ${failed ? failed' : ''}`}
    style={{ width: this.getPercentage() }} 
/>

Again, I find myself reaching out to legacy css code, "packaging" it with the component and moving on.

So, I really feel that it is a bit in the air as to what is "best" as that label will vary greatly depending on your project.

If you want to add N days to your days. You can use the plus operator as follows -

SELECT ( SYSDATE + N ) FROM DUAL;

go to "Run>edit configuration>" and select "Open select deployment target dialog" from deployment target option then run your app it will show you a dialog box you can choose your target device from there, enjoy it.

i have same issue and resolved by

 data: "Id1=" + id1 + "&Id2=" + id2

I would just go with

<tr @(if (count++ % 2 == 0){<text>class="alt-row"</text>})>

Or even better

<tr class="alt-row@(count++ % 2)">

this will give you lines like

<tr class="alt-row0">
<tr class="alt-row1">
<tr class="alt-row0">
<tr class="alt-row1">

You don't need to use the asterisk to accept a list.

Simply give the argument a name in the definition, and pass in a list like

def takes_list(a_list):
    for item in a_list:
         print item

After installing it http://meldmerge.org/ I had to tell git where it was:

git config --global merge.tool meld
git config --global diff.tool meld
git config --global mergetool.meld.path “C:\Program Files (x86)\Meld\meld.exe”

And that seems to work. Both merging and diffing with “git difftool” or “git mergetool”

If someone facing issue such as Meld crash after starting (problem indication with python) then you need to set up Meld/lib to your system environment variable as bellow C:\Program Files (x86)\Meld\lib

((ViewGroup) findViewById(android.R.id.content));// you can use this in an Activity to get your layout root view, then pass it to findAllEdittexts() method below.

Here I am iterating only EdiTexts, if you want all Views you can replace EditText with View.

SparseArray<EditText> array = new SparseArray<EditText>();

private void findAllEdittexts(ViewGroup viewGroup) {

    int count = viewGroup.getChildCount();
    for (int i = 0; i < count; i++) {
        View view = viewGroup.getChildAt(i);
        if (view instanceof ViewGroup)
            findAllEdittexts((ViewGroup) view);
        else if (view instanceof EditText) {
            EditText edittext = (EditText) view;
            array.put(editText.getId(), editText);
        }
    }
}

I experienced this error with Python2.7. It happened to me while trying to run many python programs, but I managed to reproduce it with this simple script:

#!/usr/bin/env python

import subprocess
import sys

result = subprocess.Popen([u'svn', u'info'])
if not callable(getattr(result, "__enter__", None)) and not callable(getattr(result, "__exit__", None)):
    print("foo")
print("bar")

On success, it should print out 'foo' and 'bar', and probably an error message if you're not in a svn folder.

On failure, it should print 'UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 39: ordinal not in range(128)'.

After trying to regenerate my locales and many other solutions posted in this question, I learned the error was happening because I had a special character (l) encoded in my PATH environment variable. After fixing the PATH in '~/.bashrc', and exiting my session and entering again, (apparently sourcing '~/.bashrc' didn't work), the issue was gone.

There are multiple ways how to present a timespan in the database.

time

This datatype is supported since SQL Server 2008 and is the prefered way to store a TimeSpan. There is no mapping needed. It also works well with SQL code.

public TimeSpan ValidityPeriod { get; set; }

However, as stated in the original question, this datatype is limited to 24 hours.

datetimeoffset

The datetimeoffset datatype maps directly to System.DateTimeOffset. It's used to express the offset between a datetime/datetime2 to UTC, but you can also use it for TimeSpan.

However, since the datatype suggests a very specific semantic, so you should also consider other options.

datetime / datetime2

One approach might be to use the datetime or datetime2 types. This is best in scenarios where you need to process the values in the database directly, ie. for views, stored procedures, or reports. The drawback is that you need to substract the value DateTime(1900,01,01,00,00,00) from the date to get back the timespan in your business logic.

public DateTime ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return ValidityPeriod - DateTime(1900,01,01,00,00,00); }
    set { ValidityPeriod = DateTime(1900,01,01,00,00,00) + value; }
}

bigint

Another approach might be to convert the TimeSpan into ticks and use the bigint datatype. However, this approach has the drawback that it's cumbersome to use in SQL queries.

public long ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return TimeSpan.FromTicks(ValidityPeriod); }
    set { ValidityPeriod = value.Ticks; }
}

varchar(N)

This is best for cases where the value should be readable by humans. You might also use this format in SQL queries by utilizing the CONVERT(datetime, ValidityPeriod) function. Dependent on the required precision, you will need between 8 and 25 characters.

public string ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return TimeSpan.Parse(ValidityPeriod); }
    set { ValidityPeriod = value.ToString("HH:mm:ss"); }
}

Bonus: Period and Duration

Using a string, you can also store NodaTime datatypes, especially Duration and Period. The first is basically the same as a TimeSpan, while the later respects that some days and months are longer or shorter than others (ie. January has 31 days and February has 28 or 29; some days are longer or shorter because of daylight saving time). In such cases, using a TimeSpan is the wrong choice.

You can use this code to convert Periods:

using NodaTime;
using NodaTime.Serialization.JsonNet;

internal static class PeriodExtensions
{
    public static Period ToPeriod(this string input)
    {
        var js = JsonSerializer.Create(new JsonSerializerSettings());
        js.ConfigureForNodaTime(DateTimeZoneProviders.Tzdb);
        var quoted = string.Concat(@"""", input, @"""");
        return js.Deserialize<Period>(new JsonTextReader(new StringReader(quoted)));
    }
}

And then use it like

public string ValidityPeriod { get; set; }

[NotMapped]
public Period ValidityPeriodPeriod
{
    get => ValidityPeriod.ToPeriod();
    set => ValidityPeriod = value.ToString();
}

I really like NodaTime and it often saves me from tricky bugs and lots of headache. The drawback here is that you really can't use it in SQL queries and need to do calculations in-memory.

CLR User-Defined Type

You also have the option to use a custom datatype and support a custom TimeSpan class directly. See CLR User-Defined Types for details.

The drawback here is that the datatype might not behave well with SQL Reports. Also, some versions of SQL Server (Azure, Linux, Data Warehouse) are not supported.

Value Conversions

Starting with EntityFramework Core 2.1, you have the option to use Value Conversions.

However, when using this, EF will not be able to convert many queries into SQL, causing queries to run in-memory; potentially transfering lots and lots of data to your application.

So at least for now, it might be better not to use it, and just map the query result with Automapper.

The hide_code extension allows you to hide individual cells, and/or the prompts next to them. Install as

pip3 install hide_code

Visit https://github.com/kirbs-/hide_code/ for more info about this extension.

I can relate to the problem, there should be a shorthand like...

border: 1px solid red top bottom left;

Of course that doesn't work! Kobi's answer gave me an idea. Let's say you want to do top, bottom and left, but not right. Instead of doing border-top: border-left: border-bottom: (three statements) you could do two like this, the zero cancels out the right side.

border: 1px dashed yellow;
border-width:1px 0 1px 1px;

Two statements instead of three, small improvement :-D

A really fast way to solve this problem is to make a database link from the Oracle database to the MySQL database. You can create database links to non-Oracle databases. After you have created the database link you can retrieve your data from the MySQL database with a ... create table mydata as select * from ... statement. This is called heterogeneous connectivity. This way you don't have to do anything in your .net application to move the data.

Another way is to use ODP.NET. In ODP.NET you can use the OracleBulkCopy-class.

But I don't think that inserting 160k records in an Oracle table with System.Data.OracleClient should take 25 minutes. I think you commit too many times. And do you bind your values to the insert statement with parameters or do you concatenate your values. Binding is much faster.

Latitude maximum in total is: 9 (12.3456789), longitude 10 (123.4567890), they both have maximum 7 decimals chars (At least is what i can find in Google Maps),

For example, both columns in Rails and Postgresql looks something like this:

t.decimal :latitude, precision: 9, scale: 7
t.decimal :longitude, precision: 10, scale: 7

#include <string>

using std::string;

void myReplace(string& str,
               const string& oldStr,
               const string& newStr) {
  if (oldStr.empty()) {
    return;
  }

  for (size_t pos = 0; (pos = str.find(oldStr, pos)) != string::npos;) {
    str.replace(pos, oldStr.length(), newStr);
    pos += newStr.length();
  }
}

The check for oldStr being empty is important. If for whatever reason that parameter is empty you will get stuck in an infinite loop.

But yeah use the tried and tested C++11 or Boost solution if you can.

I met the same problems and has solved.

Due to my situation, I guess your build.gradle file for app project contains snippets below:

android {
    ...
    buildTypes {
        debug {...}
        release {...}
        dexOptions {...}
    }
}

but actually, dexOptions is not a build type, you should move dexOptions section out buildTypes, like this:

android {
    ...
    dexOptions {
        ...
    }

    buildTypes {
        debug {...}
        release {...}
    }
}

Hope that can help someone.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

UPDATE Table SET Column = REPLACE(Column, char(9), '')

If access modifier of base class member function is protected OR public, you can do call member function of base class from derived class. Call to the base class non-virtual and virtual member function from derived member function can be made. Please refer the program.

#include<iostream>
using namespace std;

class Parent
{
  protected:
    virtual void fun(int i)
    {
      cout<<"Parent::fun functionality write here"<<endl;
    }
    void fun1(int i)
    {
      cout<<"Parent::fun1 functionality write here"<<endl;
    }
    void fun2()
    {

      cout<<"Parent::fun3 functionality write here"<<endl;
    }

};

class Child:public Parent
{
  public:
    virtual void fun(int i)
    {
      cout<<"Child::fun partial functionality write here"<<endl;
      Parent::fun(++i);
      Parent::fun2();
    }
    void fun1(int i)
    {
      cout<<"Child::fun1 partial functionality write here"<<endl;
      Parent::fun1(++i);
    }

};
int main()
{
   Child d1;
   d1.fun(1);
   d1.fun1(2);
   return 0;
}

Output:

$ g++ base_function_call_from_derived.cpp
$ ./a.out 
Child::fun partial functionality write here
Parent::fun functionality write here
Parent::fun3 functionality write here
Child::fun1 partial functionality write here
Parent::fun1 functionality write here

If you want to manually mask your image, here is updated code that works with retina screens

- (UIImage *)maskWithColor:(UIColor *)color
{
    CGImageRef maskImage = self.CGImage;
    CGFloat width = self.size.width * self.scale;
    CGFloat height = self.size.height * self.scale;
    CGRect bounds = CGRectMake(0,0,width,height);

    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    CGContextRef bitmapContext = CGBitmapContextCreate(NULL, width, height, 8, 0, colorSpace, kCGBitmapAlphaInfoMask & kCGImageAlphaPremultipliedLast);
    CGContextClipToMask(bitmapContext, bounds, maskImage);
    CGContextSetFillColorWithColor(bitmapContext, color.CGColor);
    CGContextFillRect(bitmapContext, bounds);

    CGImageRef cImage = CGBitmapContextCreateImage(bitmapContext);
    UIImage *coloredImage = [UIImage imageWithCGImage:cImage scale:self.scale orientation:self.imageOrientation];

    CGContextRelease(bitmapContext);
    CGColorSpaceRelease(colorSpace);
    CGImageRelease(cImage);

    return coloredImage;
}

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if block.

public String foo(@Nullable String mayBeNothing) {
   return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}

You can also throw some exception in there by swapping .orElse to orElseThrow(() -> new Exception("Dont' send a null")).

If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe... so your intention is clear.

Use textView instead then conform with its delegate, call the textViewDidChange method inside of that method call tableView.beginUpdates() and tableView.endUpdates() and don't forget to set rowHeight and estimatedRowHeight to UITableView.automaticDimension.

make your class public access modifier,

just add public keyword infront of your class name

 namespace Test
{
  public  class Delivery
    {
        private string name;
        private string address;
        private DateTime arrivalTime;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }

        public string Address
        {
            get { return address; }
            set { address = value; }
        }

        public DateTime ArrivlaTime
        {
            get { return arrivalTime; }
            set { arrivalTime = value; }
        }

        public string ToString()
        {
            { return name + address + arrivalTime.ToString(); }
        }
    }
}

Wrap the label and input in another div with a defined height. This may not work in IE versions lower than 8.

1. Launch Android Studio application
2. Choose Project Settings
3. Choose Plugin from disk, if on disk then choose that location of *.jar, in my case is GenyMotion jar
4. Click on Apply and OK.
5. Then Android studio will ask for Restart.

That's all Folks!

Not really the answer to your question, but if you want to have something like an array that can grow and shrink you should not use an array in java. You are probably best of by using ArrayList or another List implementation.

You can then call size() on it to get it's size.

Bonus answer since this use-case brought me here:

In the case where you need to do this as some other user

echo "some output" | sudo -u some_user tee /some/path/some_file

Note that the echo will happen as you and the file write will happen as "some_user" what will NOT work is if you were to run the echo as "some_user" and redirect the output with >> "some_file" because the file redirect will happen as you.

Hint: tee also supports append with the -a flag, if you need to replace a line in a file as another user you could execute sed as the desired user.

Why are you sending it through a post if you already have it on the server (PHP) side?

Why not just save the array to s $_SESSION variable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.

It all depends on what you really want to do.

This one worked in my python script:

print "\t%-5s %-10s %-10s %-10s %-10s %-10s %-20s"  % (thread[0],thread[1],thread[2],thread[3],thread[4],thread[5],thread[6])

You can create your own custom selector :hasValue and then use that to find, filter, or test any other jQuery elements.

jQuery.expr[':'].hasValue = function(el,index,match) {
  return el.value != "";
};

Then you can find elements like this:

var data = $("form input:hasValue").serialize();

Or test the current element with .is()

var elHasValue = $("#name").is(":hasValue");

jQuery.expr[':'].hasValue = function(el) {_x000D_
  return el.value != "";_x000D_
};_x000D_
_x000D_
_x000D_
var data = $("form input:hasValue").serialize();_x000D_
console.log(data)_x000D_
_x000D_
_x000D_
var elHasValue = $("[name='LastName']").is(":hasValue");_x000D_
console.log(elHasValue)

label { display: block; margin-top:10px; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<form>_x000D_
  <label>_x000D_
    First Name:_x000D_
    <input type="text" name="FirstName" value="Frida" />_x000D_
  </label>_x000D_
_x000D_
  <label>_x000D_
    Last Name:_x000D_
    <input type="text" name="LastName" />_x000D_
  </label>_x000D_
</form>

Grep the folder tree's *.vcxproj files. Replace <WindowsTargetPlatformVersion>8.1</WindowsTargetPlatformVersion> with <WindowsTargetPlatformVersion>10.0</WindowsTargetPlatformVersion> or whatever SDK version you get when you update one of the projects.

The second example would be the one to go with, not just for readability, but because of the fact that in the first example, If NOT value1 would return a boolean value to be compared against value2. IOW, you need to rewrite that example as

If NOT (value1 = value2)

which just makes the use of the NOT keyword pointless.

Use LinkedHashMap instead of HashMap It will always return keys in same order (as insertion) when calling keySet()

                        while executing a register, and it doesn't work inside
                        a mapping.  {Vi: no recording}

Python doesn't have a preprocessor, nor does it have constants in the sense that they can't be changed - you can always change (nearly, you can emulate constant object properties, but doing this for the sake of constant-ness is rarely done and not considered useful) everything. When defining a constant, we define a name that's upper-case-with-underscores and call it a day - "We're all consenting adults here", no sane man would change a constant. Unless of course he has very good reasons and knows exactly what he's doing, in which case you can't (and propably shouldn't) stop him either way.

But of course you can define a module-level name with a value and use it in another module. This isn't specific to constants or anything, read up on the module system.

# a.py
MY_CONSTANT = ...

# b.py
import a
print a.MY_CONSTANT

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

Obviously @Ian Ringrose's central thesis that you should be using a library for this is the best single answer here (hence a +1), but for minimal throwaway or demo code here's a concrete illustration of @SLaks's subtle comment on @Jon Skeet's more granular (+1'd) answer:

public List<XXX> Load( <<args>> )
{
    using ( var connection = CreateConnection() )
    using ( var command = Create<<ListXXX>>Command( <<args>>, connection ) )
    {
        connection.Open();
        using ( var reader = command.ExecuteReader() )
            return reader.Cast<IDataRecord>()
                .Select( x => new XXX( x.GetString( 0 ), x.GetString( 1 ) ) )
                .ToList();
    }
}

As in @Jon Skeet's answer, the

            .Select( x => new XXX( x.GetString( 0 ), x.GetString( 1 ) ) )

bit can be extracted into a helper (I like to dump them in the query class):

    public static XXX FromDataRecord( this IDataRecord record)
    {
        return new XXX( record.GetString( 0 ), record.GetString( 1 ) );
    }

and used as:

            .Select( FromDataRecord )

For me it works only with any of these solutions

$(this).select2('val', null);

or

$(this).select2('val', '');

why not use flexbox ? so wrap them into another div like that

.flexContainer { _x000D_
   _x000D_
  margin: 2px 10px;_x000D_
  display: flex;_x000D_
} _x000D_
_x000D_
.left {_x000D_
  flex-basis : 30%;_x000D_
}_x000D_
_x000D_
.right {_x000D_
  flex-basis : 30%;_x000D_
}

<form id="new_production" class="simple_form new_production" novalidate="novalidate" method="post" action="/projects/1/productions" accept-charset="UTF-8">_x000D_
    <div style="margin:0;padding:0;display:inline">_x000D_

        <input type="hidden" value="2UQCUU+tKiKKtEiDtLLNeDrfBDoHTUmz5Sl9+JRVjALat3hFM=" name="authenticity_token">_x000D_
    </div>_x000D_
    <div class="flexContainer">_x000D_
      <div class="left">Proj Name:</div>_x000D_
      <div class="right">must have a name</div>_x000D_
    </div>_x000D_
    <div class="input string required"> </div>_x000D_
 </form>

feel free to play with flex-basis percentage to get more customized space.

I created the following function to generate an html table from an arbitrary JSON object:

function toTable(json, colKeyClassMap, rowKeyClassMap){
    let tab;
    if(typeof colKeyClassMap === 'undefined'){
        colKeyClassMap = {};
    }
    if(typeof rowKeyClassMap === 'undefined'){
        rowKeyClassMap = {};
    }

    const newTable = '<table class="table table-bordered table-condensed table-striped" />';
    if($.isArray(json)){
        if(json.length === 0){
            return '[]'
        } else {
            const first = json[0];
            if($.isPlainObject(first)){
                tab = $(newTable);
                const row = $('<tr />');
                tab.append(row);
                $.each( first, function( key, value ) {
                    row.append($('<th />').addClass(colKeyClassMap[key]).text(key))
                });

                $.each( json, function( key, value ) {
                    const row = $('<tr />');
                    $.each( value, function( key, value ) {
                        row.append($('<td />').addClass(colKeyClassMap[key]).html(toTable(value, colKeyClassMap, rowKeyClassMap)))
                    });
                    tab.append(row);
                });

                return tab;
            } else if ($.isArray(first)) {
                tab = $(newTable);

                $.each( json, function( key, value ) {
                    const tr = $('<tr />');
                    const td = $('<td />');
                    tr.append(td);
                    $.each( value, function( key, value ) {
                        td.append(toTable(value, colKeyClassMap, rowKeyClassMap));
                    });
                    tab.append(tr);
                });

                return tab;
            } else {
                return json.join(", ");
            }
        }

    } else if($.isPlainObject(json)){
        tab = $(newTable);
        $.each( json, function( key, value ) {
            tab.append(
                $('<tr />')
                    .append($('<th style="width: 20%;"/>').addClass(rowKeyClassMap[key]).text(key))
                    .append($('<td />').addClass(rowKeyClassMap[key]).html(toTable(value, colKeyClassMap, rowKeyClassMap))));
        });
        return tab;
    } else if (typeof json === 'string') {
        if(json.slice(0, 4) === 'http'){
            return '<a target="_blank" href="'+json+'">'+json+'</a>';
        }
        return json;
    } else {
        return ''+json;
    }
};

So you can simply call:

$('#mydiv').html(toTable([{"city":"AMBALA","cStatus":"Y"},{"city":"ASANKHURD","cStatus":"Y"},{"city":"ASSANDH","cStatus":"Y"}]));

Private Sub Command0_Click()

Application.FollowHyperlink "D:\1Zsnsn\SusuBarokah\20151008 Inventory.mdb"

End Sub

If you are not wanting to use async you can add .Result to force the code to execute synchronously:

private string GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters)).Result;
    var contents = response.Content.ReadAsStringAsync().Result;

    return contents;
 }  

Full code that shows now and 10 minutes added.....

$nowtime = date("Y-m-d H:i:s");
echo $nowtime;
$date = date('Y-m-d H:i:s', strtotime($nowtime . ' + 10 minute'));
echo "<br>".$date;

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

It should be:

...
WHERE LastName LIKE '%' + @LastName + '%';

Instead of:

...
WHERE LastName LIKE '%@LastName%'

You can do it by using include_once() function in php. Construct a header part in the name of header.php and construct the footer part by footer.php. Finally include all the content in one file.

For example:

header.php

<html>
<title>
<link href="sample.css">

footer.php

</html>

So the final files look like

include_once("header.php") 

body content(The body content changes based on the file dynamically)

include_once("footer.php") 

There are different ways to do this, but the server can't detect when de browser gets closed so destroying it then is hard.

• timeout session.

Either create a new session with the current time or add a time variable to the current session. and then check it when you start up or perform an action to see if the session has to be removed.

session_start();
$_SESSION["timeout"] = time();
//if 100 seconds have passed since creating session delete it.
if(time() - $_SESSION["timeout"] > 100){ 
    unset($_SESSION["timeout"];
}

• ajax

Make javascript perform an ajax call that will delete the session, with onbeforeunload() a javascript function that calls a final action when the user leaves the page. For some reason this doesnt always work though.

• delete it on startup.

If you always want the user to see the login page on startup after the page has been closed you can just delete the session on startup.

<? php
session_start();
unset($_SESSION["session"]);

and there probably are some more.

I've added upon the code submitted by jSnake04 and Dasun herein. I've added code to create lists of objects from JArray instances. It has two-way recursion but as it is functioning on a fixed, finite tree model, there is no risk of stack overflow unless the data is massive.

If you have or are already using lodash, use last instead:

_.last(str);

Not only is it more concise and obvious than the vanilla JS, it also safer since it avoids Uncaught TypeError: Cannot read property X of undefined when the input is null or undefined so you don't need to check this beforehand:

// Will throws Uncaught TypeError if str is null or undefined
str.slice(-1); // 
str.charAt(str.length -1);

// Returns undefined when str is null or undefined
_.last(str);

There is no error in the, but the mysqli PHP extension is not installed on your machine. Please contact your service provider to fix this issue.

puts or p is a good start to do that.

p "asd"       # => "asd"
puts "asd"    # => asd

here is more information about that: http://www.ruby-doc.org/core-1.9.3/ARGF.html

I would use null to show that there is no value for that particular key. For example, use null to represent that "number of devices in your household connects to internet" is unknown.

On the other hand, use {} if that particular key is not applicable. For example, you should not show a count, even if null, to the question "number of cars that has active internet connection" is asked to someone who does not own any cars.

I would avoid defaulting any value unless that default makes sense. While you may decide to use null to represent no value, certainly never use "null" to do so.

Controller :

public ActionResult Refresh(string ID)
    {
        DetailsViewModel vm = new DetailsViewModel();  // Model
        vm.productDetails = _product.GetproductDetails(ID); 
        /* "productDetails " is a property in "DetailsViewModel"
        "GetProductDetails" is a method in "Product" class
        "_product" is an interface of "Product" class */

        return PartialView("_Details", vm); // Details is a partial view
    }

In yore index page you should to have refresh link :

     <a href="#" id="refreshItem">Refresh</a>

This Script should be also in your index page:

<script type="text/javascript">

    $(function () {
    $('a[id=refreshItem]:last').click(function (e) {
        e.preventDefault();

        var url = MVC.Url.action('Refresh', 'MyController', { itemId: '@(Model.itemProp.itemId )' }); // Refresh is an Action in controller, MyController is a controller name

        $.ajax({
            type: 'GET',
            url: url,
            cache: false,
            success: function (grid) {
                $('#tabItemDetails').html(grid);
                clientBehaviors.applyPlugins($("#tabProductDetails")); // "tabProductDetails" is an id of div in your "Details partial view"
            }
        });
    });
});

For those of you on AWS (Amazon Web Services), remember to add a rule for your SSL port (in my case 443) to your security groups. I was getting this error because I forgot to open the port.

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

If all you want is to print from Monday onwards, you can use list's index method to find the position where "Monday" is in the list, and iterate from there as explained in other posts. Using list.index saves you hard-coding the index for "Monday", which is a potential source of error:

days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
for d in days[days.index('Monday'):] :
   print d

I had this problem when I added Swift source code to an existing ObjC static framework (dynamic framework with Mach-O type "Static Library").

The fix was setting CLANG_ENABLE_MODULES ("Enable Modules" in build settings) to YES

The simplest way of getting parent function name is:

$caller = next(debug_backtrace())['function'];

h:button - clicking on a h:button issues a bookmarkable GET request.

h:commandbutton - Instead of a get request, h:commandbutton issues a POST request which sends the form data back to the server.

You can also set the TMPDIR environment variable.

In some situations (Docker in my case) it's more convenient to set an environment variable than to update a config file.

In addition to the other answers, this error can result if there's an inconsistency in an order by clause. For instance:

select 
    substr(year_month, 1, 4)
    ,count(*) as tot
from
    schema.tbl
group by
    substr(year_month, 1, 4)
order by
    year_month

After updating your android studio to 3.0, if this error occurs just update the gradle properties, these are the settings which solved my issue:

compileSdkVersion 26

targetSdkVersion 26

buildToolsVersion '26.0.2'

The Gantt charts given by Hifzan and Raja are for FCFS algorithms.

With an SJF algorithm, processes can be interrupted. That is, every process doesn't necessarily execute straight through their given burst time.

P3|P2|P4|P3|P5|P1|P5

1|2|3|5|7|8|11|14

P3 arrives at 1ms, then is interrupted by P2 and P4 since they both have smaller burst times, and then P3 resumes. P5 starts executing next, then is interrupted by P1 since P1's burst time is smaller than P5's. You must note the arrival times and be careful. These problems can be trickier than how they appear at-first-glance.

EDIT: This applies only to Preemptive SJF algorithms. A plain SJF algorithm is non-preemptive, meaning it does not interrupt a process.

Replace

f = open(D\\python\\HW\\2_1 - Copy.cp,"r");

by

f = open("D:\\python\\HW\\2_1 - Copy.cp", "r")

1. File path needs to be a string (constant)
2. need colon in Windows file path
3. space after comma for better style
4. ; after statement is allowed but fugly.

That is the simple way of converting string into util date and sql date

String startDate="12-31-2014";
SimpleDateFormat sdf1 = new SimpleDateFormat("MM-dd-yyyy");
java.util.Date date = sdf1.parse(startDate);
java.sql.Date sqlStartDate = new java.sql.Date(date.getTime()); 

Slightly modifying answer by @Yogeesh Seralathan. His answer works perfectly, just run these commands at once.

Here:

def random_color():
    rgbl=[255,0,0]
    random.shuffle(rgbl)
    return tuple(rgbl)

The result is either red, green or blue. The method is not applicable to other sets of colors though, where you'd have to build a list of all the colors you want to choose from and then use random.choice to pick one at random.

This is how I make forms full screen.

private void button1_Click(object sender, EventArgs e)
{
    int minx, miny, maxx, maxy;
    inx = miny = int.MaxValue;
    maxx = maxy = int.MinValue;

    foreach (Screen screen in Screen.AllScreens)
    {
        var bounds = screen.Bounds;
        minx = Math.Min(minx, bounds.X);
        miny = Math.Min(miny, bounds.Y);
        maxx = Math.Max(maxx, bounds.Right);
        maxy = Math.Max(maxy, bounds.Bottom);
    }

    Form3 fs = new Form3();
    fs.Activate();
    Rectangle tempRect = new Rectangle(1, 0, maxx, maxy);
    this.DesktopBounds = tempRect;
}

I had the same issue and resolved by adding "Connection Time" value in web.config file. locate the connectionStrings and add Connection Timeout=3600"

here is the sample

  <connectionStrings>
    <add name="MyConn" providerName="System.Data.SqlClient" connectionString="Data Source=MySQLServer;Initial Catalog=MyDB;User ID=sa;Password=123;Connection Timeout=3600" />
  </connectionStrings>

For Fish terminal users on Mac (I believe it's available on Linux as well), this should work:

set -Ux JAVA_8 (/usr/libexec/java_home --version 1.8)
set -Ux JAVA_12 (/usr/libexec/java_home --version 12)
set -Ux JAVA_HOME $JAVA_8       //or whichever version you want as default

Once id of iframe is set, you can access iframe from inner document as shown below.

var iframe = parent.document.getElementById(frameElement.id);

Works well in IE, Chrome and FF.

Paste this code to your pom.xml file. It works for me.

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.6.1</version>
    <scope>test</scope>
</dependency>

Git’s executable is actually located in: C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin\git.exe

Now that we have located the executable all we have to do is add it to our PATH:

• Right-Click on My Computer
• Click Advanced System Settings
• Click Environment Variables
• Then under System Variables look for the path variable and click edit
• Add the path to git’s bin and cmd at the end of the string like this:

;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd

In this case what you can do is : Go in developer options on the device Uncheck "USB Debugging" then check it again A confirmation box should then appear DvxWifiScan

Let me work you through the following simple steps:

Steps:

First, create a table on hive using the field names in your csv file. Lets say for example, your csv file contains three fields (id, name, salary) and you want to create a table in hive called "staff". Use the below code to create the table in hive.

hive> CREATE TABLE Staff (id int, name string, salary double) row format delimited fields terminated by ',';

Second, now that your table is created in hive, let us load the data in your csv file to the "staff" table on hive.

hive>  LOAD DATA LOCAL INPATH '/home/yourcsvfile.csv' OVERWRITE INTO TABLE Staff;

Lastly, display the contents of your "Staff" table on hive to check if the data were successfully loaded

hive> SELECT * FROM Staff;

Thanks.

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

You should be denoting the call by reference in the function definition, not the actual call. Since PHP started showing the deprecation errors in version 5.3, I would say it would be a good idea to rewrite the code.

From the documentation:

There is no reference sign on a function call - only on function definitions. Function definitions alone are enough to correctly pass the argument by reference. As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use & in foo(&$a);.

For example, instead of using:

// Wrong way!
myFunc(&$arg);               # Deprecated pass-by-reference argument
function myFunc($arg) { }

Use:

// Right way!
myFunc($var);                # pass-by-value argument
function myFunc(&$arg) { }
