You've just published that private key, so now the whole world knows what it is. Hopefully that was just for testing.

EDIT: Others have noted that the openssl text header of the published key, -----BEGIN RSA PRIVATE KEY-----, indicates that it is PKCS#1. However, the actual Base64 contents of the key in question is PKCS#8. Evidently the OP copy and pasted the header and trailer of a PKCS#1 key onto the PKCS#8 key for some unknown reason. The sample code I've provided below works with PKCS#8 private keys.

Here is some code that will create the private key from that data. You'll have to replace the Base64 decoding with your IBM Base64 decoder.

public class RSAToy {

    private static final String BEGIN_RSA_PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\n"
            + "MIIEuwIBADAN ...skipped the rest\n"
         // + ...   
         // + ... skipped the rest
         // + ...   
            + "-----END RSA PRIVATE KEY-----";

    public static void main(String[] args) throws Exception {

        // Remove the first and last lines

        String privKeyPEM = BEGIN_RSA_PRIVATE_KEY.replace("-----BEGIN RSA PRIVATE KEY-----\n", "");
        privKeyPEM = privKeyPEM.replace("-----END RSA PRIVATE KEY-----", "");
        System.out.println(privKeyPEM);

        // Base64 decode the data

        byte [] encoded = Base64.decode(privKeyPEM);

        // PKCS8 decode the encoded RSA private key

        PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(encoded);
        KeyFactory kf = KeyFactory.getInstance("RSA");
        PrivateKey privKey = kf.generatePrivate(keySpec);

        // Display the results

        System.out.println(privKey);
    }
}

Your code is way more cluttered than necessary.

Replace (Not (X Is Nothing)) with X IsNot Nothing and omit the outer parentheses:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For i As Integer = 0 To comp.Container.Components.Count() - 1
        fixUIIn(comp.Container.Components(i), style)
    Next
End If

Much more readable. … Also notice that I’ve removed the redundant Step 1 and the probably redundant .Item.

But (as pointed out in the comments), index-based loops are out of vogue anyway. Don’t use them unless you absolutely have to. Use For Each instead:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For Each component In comp.Container.Components
        fixUIIn(component, style)
    Next
End If

Python 3 (and 2)

import base64
a = 'eW91ciB0ZXh0'
base64.b64decode(a)

Python 2

A quick way to decode it without importing anything:

'eW91ciB0ZXh0'.decode('base64')

or more descriptive

>>> a = 'eW91ciB0ZXh0'
>>> a.decode('base64')
'your text'

Though this answer is unlikely to be seen, I think the following clarification is worth making:

• the (n) behind an integer data type in MySQL is specifying the display width
• the display width does NOT limit the length of the number returned from a query
• the display width DOES limit the number of zeroes filled for a zero filled column so the total number matches the display width (so long as the actual number does not exceed the display width, in which case the number is shown as is)
• the display width is also meant as a useful tool for developers to know what length the value should be padded to

A BIT OF DETAIL
the display width is, apparently, intended to provide some metadata about how many zeros to display in a zero filled number.
It does NOT actually limit the length of a number returned from a query if that number goes above the display width specified.
To know what length/width is actually allowed for an integer data type in MySQL see the list & link: (types: TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT);
So having said the above, you can expect the display width to have no affect on the results from a standard query, unless the columns are specified as ZEROFILL columns
OR
in the case the data is being pulled into an application & that application is collecting the display width to use for some other sort of padding.

[[UIDevice currentDevice] model] just returns iPhone or iPod, you don't get the numbers of the model that would let you differentiate between different generations of devices.

Code this method:

#include <sys/sysctl.h>
...

+ (NSString *)getModel {
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *model = malloc(size);
    sysctlbyname("hw.machine", model, &size, NULL, 0);
    NSString *deviceModel = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];
    free(model);
    return deviceModel;
}

And call the method [self getModel] whenever you need the model and you'll get i.e: "iPhone5,1" for the ridiculously thin and speedy iPhone 5.

One good practice is to create a class called Utils.h/Utils.m and put methods like getModel there so you can get this info from anywhere in your App simply by importing the class and invoking [Utils getModel];

Use the CSS Class to prevent from Editing the Div Elements

CSS:

.divoverlay
{
position:absolute;
width:100%;
height:100%;
background-color:transparent;
z-index:1;
top:0;
}

JS:

$('#divName').append('<div class=divoverlay></div>');

Or add the class name in HTML Tag. It will prevent from editing the Div Elements.

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:

* Issue a CHECKPOINT command to free up log space in the log file.

* Check the available log space with DBCC SQLPERF('logspace'). If only a small 
  percentage of your log file is actually been used, you can try a DBCC SHRINKFILE 
  command. This can however possibly introduce corruption in your database. 

* If you have another drive with space available you can try to add a file there in 
  order to get enough space to attempt to resolve the issue.

Hope this will help you in finding your solution.

The element.style property lets you know only the CSS properties that were defined as inline in that element (programmatically, or defined in the style attribute of the element), you should get the computed style.

Is not so easy to do it in a cross-browser way, IE has its own way, through the element.currentStyle property, and the DOM Level 2 standard way, implemented by other browsers is through the document.defaultView.getComputedStyle method.

The two ways have differences, for example, the IE element.currentStyle property expect that you access the CCS property names composed of two or more words in camelCase (e.g. maxHeight, fontSize, backgroundColor, etc), the standard way expects the properties with the words separated with dashes (e.g. max-height, font-size, background-color, etc).

Also, the IE element.currentStyle will return all the sizes in the unit that they were specified, (e.g. 12pt, 50%, 5em), the standard way will compute the actual size in pixels always.

I made some time ago a cross-browser function that allows you to get the computed styles in a cross-browser way:

function getStyle(el, styleProp) {
  var value, defaultView = (el.ownerDocument || document).defaultView;
  // W3C standard way:
  if (defaultView && defaultView.getComputedStyle) {
    // sanitize property name to css notation
    // (hypen separated words eg. font-Size)
    styleProp = styleProp.replace(/([A-Z])/g, "-$1").toLowerCase();
    return defaultView.getComputedStyle(el, null).getPropertyValue(styleProp);
  } else if (el.currentStyle) { // IE
    // sanitize property name to camelCase
    styleProp = styleProp.replace(/\-(\w)/g, function(str, letter) {
      return letter.toUpperCase();
    });
    value = el.currentStyle[styleProp];
    // convert other units to pixels on IE
    if (/^\d+(em|pt|%|ex)?$/i.test(value)) { 
      return (function(value) {
        var oldLeft = el.style.left, oldRsLeft = el.runtimeStyle.left;
        el.runtimeStyle.left = el.currentStyle.left;
        el.style.left = value || 0;
        value = el.style.pixelLeft + "px";
        el.style.left = oldLeft;
        el.runtimeStyle.left = oldRsLeft;
        return value;
      })(value);
    }
    return value;
  }
}

The above function is not perfect for some cases, for example for colors, the standard method will return colors in the rgb(...) notation, on IE they will return them as they were defined.

I'm currently working on an article in the subject, you can follow the changes I make to this function here.

Database name is a value of SqlConnectionStringBuilder.InitialCatalog property.

Please use DateTimeFormatter ISO_DATE_TIME = DateTimeFormatter.ISO_DATE_TIME; instead of DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss") or any pattern

This fixed my problem Below

java.time.format.DateTimeParseException: Text '2019-12-18T19:00:00.000Z' could not be parsed at index 10

In Visual Studio 2010, if you type "ctor" (without the quotes), IntelliSense should load, showing you "ctor" in the list. Now press TAB twice, and you should have generated an empty constructor.

You are probably not assigning it after doing the replacement or replacing the wrong thing. Try :

String haystack = "abcd=0; efgh=1";
String result = haystack.replaceAll("abcd","dddd");

I got the same error message. In my case, it was due to not using quotes.

Although the column was supposed to have only numbers, it was a Varchar column, and one of the rows had a letter in it.

So I was doing this:

select * from mytable where myid = 1234

While I should be doing this:

select * from mytable where myid = '1234'

If the column had all numbers, the conversion would have worked, but not in this case.

Why not one more answer? setState() and the setState()-triggered render() have both completed executing when you call componentDidMount() (the first time render() is executed) and/or componentDidUpdate() (any time after render() is executed). (Links are to ReactJS.org docs.)

Example with componentDidUpdate()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>;
this.parent.setState({'data':'hello!'});

Render parent...

componentDidMount() {           // componentDidMount() gets called after first state set
    console.log(this.state.data);   // output: "hello!"
}
componentDidUpdate() {          // componentDidUpdate() gets called after all other states set
    console.log(this.state.data);   // output: "hello!"
}

Example with componentDidMount()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>
this.parent.setState({'data':'hello!'});

Render parent...

render() {              // render() gets called anytime setState() is called
    return (
        <ChildComponent
            state={this.state}
        />
    );
}

After parent rerenders child, see state in componentDidUpdate().

componentDidMount() {           // componentDidMount() gets called anytime setState()/render() finish
console.log(this.props.state.data); // output: "hello!"
}

if you are handling the config changes in your fragment activity specified in android manifest like this

<activity
    android:name=".courses.posts.EditPostActivity"
    android:configChanges="keyboardHidden|orientation"
    android:screenOrientation="unspecified" />

then the onSaveInstanceState of the fragment will not be invoked and the savedInstanceState object will always be null.

Shouldn't creating a new Runnable class make a new second thread?

No. new Runnable does not create second Thread.

What is the purpose of the Runnable class here apart from being able to pass a Runnable class to postAtTime?

Runnable is posted to Handler. This task runs in the thread, which is associated with Handler.

If Handler is associated with UI Thread, Runnable runs in UI Thread.

If Handler is associated with other HandlerThread, Runnable runs in HandlerThread

To explicitly associate Handler to your MainThread ( UI Thread), write below code.

Handler  mHandler = new Handler(Looper.getMainLooper();

If you write is as below, it uses HandlerThread Looper.

HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
    xmlDoc.async = false;_x000D_
    xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Postal Code_x000D_
console.log(xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue);

i've found one solution:

$("#someElement")[0].className.match("test")

but somehow i believe that there's a better way!

For the record, this is documented in How do I add resources to my JAR? (illustrated for unit tests but the same applies for a "regular" resource):

To add resources to the classpath for your unit tests, you follow the same pattern as you do for adding resources to the JAR except the directory you place resources in is ${basedir}/src/test/resources. At this point you would have a project directory structure that would look like the following:

my-app
|-- pom.xml
`-- src
    |-- main
    |   |-- java
    |   |   `-- com
    |   |       `-- mycompany
    |   |           `-- app
    |   |               `-- App.java
    |   `-- resources
    |       `-- META-INF
    |           |-- application.properties
    `-- test
        |-- java
        |   `-- com
        |       `-- mycompany
        |           `-- app
        |               `-- AppTest.java
        `-- resources
            `-- test.properties

In a unit test you could use a simple snippet of code like the following to access the resource required for testing:

...

// Retrieve resource
InputStream is = getClass().getResourceAsStream("/test.properties" );

// Do something with the resource

...

There may be two causes:

1. It is case-sensitive: DataFrame .... Dataframe, dataframe will not work.

2. You have not install pandas (pip install pandas) in the python path.

With "Asset Type" set to "Image", try setting the same image for the foreground and background layers, keeping the same "Resize" percentage.

There are two ways to create custom ToggleButton

1) By defining custom background 2) By creating custom button

Check http://www.zoftino.com/android-toggle-button for custom styles

Toggle button with custom background

Define drawable as xml resource like below and set it as background of toggle button. In the below example, drawable toggle_color is a color selector, you need to define this also.

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="4dp"
    android:insetTop="4dp"
    android:insetRight="4dp"
    android:insetBottom="4dp">
    <layer-list android:paddingMode="stack">
        <item>
            <ripple android:color="?attr/android:colorControlHighlight">
                <item>
                    <shape android:shape="rectangle"
                        android:tint="?attr/android:colorButtonNormal">
                        <corners android:radius="8dp"/>
                        <solid android:color="@android:color/white" />
                        <padding android:left="8dp"
                            android:top="6dp"
                            android:right="8dp"
                            android:bottom="6dp" />
                    </shape>
                </item>
            </ripple>
        </item>
        <item android:gravity="left|fill_vertical">
            <shape android:shape="rectangle">
                <corners android:radius="4dp"/>
                <size android:width="8dp" />
                <solid android:color="@color/toggle_color" />
            </shape>
        </item>
        <item android:gravity="right|fill_vertical">
            <shape android:shape="rectangle">
                <corners android:radius="4dp"/>
                <size android:width="8dp" />
                <solid android:color="@color/toggle_color" />
            </shape>
        </item>
    </layer-list>
</inset>

Toggle button with custom button

Create your own images for two state of toggle button (make sure images exist for all sizes of screens) and place them in drawable folder, create selector and set it as button.

   <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@drawable/toggle_on" />
    <item android:drawable="@drawable/toggle_off" />
</selector>

UPDATE: Eclipse Mars EE and later have native support for Tomcat8. Use this only if you have an earlier version of eclipse.

The latest version of Eclipse still does not support Tomcat 8, but you can add the new version of WTP and Tomcat 8 support will be added natively. To do this:

• Download the latest version of Eclipse for Java EE
• Go to the WTP downloads page, select the latest version (currently 3.6), and download the zip (under Traditional Zip Files...Web App Developers). Here's the current link.
• Copy the all of the files in features and plugins directories of the downloaded WTP into the corresponding Eclipse directories in your Eclipse folder (overwriting the existing files).

Start Eclipse and you should have a Tomcat 8 option available when you go to deploy.

I am using MySQL 5.6 and there is a DATE function to extract only the date part from date time. So the simple solution to the question is -

 select * from test where DATE(date) = '2014-03-19';

http://dev.mysql.com/doc/refman/5.6/en/date-and-time-functions.html

I'm a newbie to Python and the offhand comment about Python 3 in the accepted solution was confusing. For posterity, the code to do this in Python 3 is

import urllib.request
data = urllib.request.urlopen(target_url)

for line in data:
    ...

or alternatively

from urllib.request import urlopen
data = urlopen(target_url)

Note that just import urllib does not work.

If you want to set environment variables permanently in Git-Bash, you have two options:

1. Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.

2. Set up env variables in .bash_profile file.

.bash_profile is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOME Windows environment variable.

.bash_profile file uses the regular Bash syntax and commands

# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir

# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

Read more information about Bash configurations files.

Pesonally tested on 10g ;-)

From http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php

Try using BindingExpression.UpdateTarget()

The following should work and not require any permissions in the manifest (basically override shouldOverrideUrlLoading and handle links separately from tel, mailto, etc.):

    mWebView = (WebView) findViewById(R.id.web_view);

    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mWebView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle things like tel, mailto, etc.
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity( intent );
            return true;
        }
    });
    mWebView.loadUrl(url);

Also, note that in the above snippet I am enabling JavaScript, which you will also most likely want, but if for some reason you don't, just remove those 2 lines.

Use ax.yaxis.tick_right()

for example:

from matplotlib import pyplot as plt

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
plt.plot([2,3,4,5])
plt.show()

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

& and | provide the same outcome as the && and || operators. The difference is that they always evaluate both sides of the expression where as && and || stop evaluating if the first condition is enough to determine the outcome.

Works for me by installing the first the following pip packages: libpq-dev and postgresql-common

Nothing else has worked so far.

Select in :

1. Data Source: Microsoft SQL Server (SqlClient)
2. Server name: (localdb)\MSSQLLocalDB
3. Log on to the server: Use Windows Authentication

You can simply define the useState like that:

const [, forceUpdate] = React.useState(0);

And usage: forceUpdate(n => !n)

Hope this help !

Its also interesting to observe this

To iterate over the indices of a sequence, you can combine range() and len() as follows:

a = ['Mary', 'had', 'a', 'little', 'lamb']
for i in range(len(a)):
  print(i, a[i])

output

0 Mary
1 had
2 a
3 little
4 lamb

Edit#1: Alternate way:

When looping through a sequence, the position index and corresponding value can be retrieved at the same time using the enumerate() function.

for i, v in enumerate(['tic', 'tac', 'toe']):
  print(i, v)

output

0 tic
1 tac
2 toe

$.each(result, function(key, value) {
  console.log(key+ ':' + value);
});

Angular 2 simple dropdown selected value

It may help someone as I need to only show selected value, don't need to declare something in component and etc.

If your status is coming from the database then you can show selected value this way.

<div class="form-group">
    <label for="status">Status</label>
    <select class="form-control" name="status" [(ngModel)]="category.status">
       <option [value]="1" [selected]="category.status ==1">Active</option>
       <option [value]="0" [selected]="category.status ==0">In Active</option>
    </select>
</div>

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

Might have todo with one of these:

1. Install a newer SDK.
2. In .csproj check for Reference Include="netstandard"
3. Check the assembly versions in the compilation tags in the Views\Web.config and Web.config.

It looks like Java provides a concurrent Set implementation with its ConcurrentSkipListSet. A SkipList Set is just a special kind of set implementation. It still implements the Serializable, Cloneable, Iterable, Collection, NavigableSet, Set, SortedSet interfaces. This might work for you if you only need the Set interface.

I'd also suggest moving the event handler outside render.

var OnSubmitTest = React.createClass({

  submit: function(e){
    e.preventDefault();
    alert('it works!');
  }

  render: function() {
    return (
      <form onSubmit={this.submit}>
        <button>Click me</button>
      </form>
    );
  }
});

I remember it this way:

1. IEnumerable has one method GetEnumerator() which allows one to read through the values in a collection but not write to it. Most of the complexity of using the enumerator is taken care of for us by the for each statement in C#. IEnumerable has one property: Current, which returns the current element.

2. ICollection implements IEnumerable and adds few additional properties the most use of which is Count. The generic version of ICollection implements the Add() and Remove() methods.

3. IList implements both IEnumerable and ICollection, and add the integer indexing access to items (which is not usually required, as ordering is done in database).

s1 = []
for i in range(11):
   s1.append(i)

print s1

To create a list, just use these brackets: "[]"

To add something to a list, use list.append()

ECMAScript 5 supports trim and this has been implemented in Firefox.

As of C++17 there's also std::from_chars. The following function takes a string of hex characters and returns a vector of T:

#include <charconv>

template<typename T>
std::vector<T> hexstr_to_vec(const std::string& str, unsigned char chars_per_num = 2)
{
  std::vector<T> out(str.size() / chars_per_num, 0);

  T value;
  for (int i = 0; i < str.size() / chars_per_num; i++) {
    std::from_chars<T>(
      str.data() + (i * chars_per_num),
      str.data() + (i * chars_per_num) + chars_per_num,
      value,
      16
    );
    out[i] = value;
  }

  return out;
}

Taking in consideration the other answers I would do something like this, thanks!

.table-responsive {
    @include media-breakpoint-up(md) {
        display: table;
    }
}

For me, I had to change a line of code in my local_env.yml to get the rspec tests to run.

I had originally had:

REDIS_HOST: 'redis'

and changed it to:

REDIS_HOST: 'localhost'

and the test ran fine.

For random hash values, some engineers said golden ratio prime number(2654435761) is a bad choice, with my testing results, I found that it's not true; instead, 2654435761 distributes the hash values pretty good.

#define MCR_HashTableSize 2^10

unsigned int
Hash_UInt_GRPrimeNumber(unsigned int key)
{
  key = key*2654435761 & (MCR_HashTableSize - 1)
  return key;
}

The hash table size must be a power of two.

I have written a test program to evaluate many hash functions for integers, the results show that GRPrimeNumber is a pretty good choice.

I have tried:

1. total_data_entry_number / total_bucket_number = 2, 3, 4; where total_bucket_number = hash table size;
2. map hash value domain into bucket index domain; that is, convert hash value into bucket index by Logical And Operation with (hash_table_size - 1), as shown in Hash_UInt_GRPrimeNumber();
3. calculate the collision number of each bucket;
4. record the bucket that has not been mapped, that is, an empty bucket;
5. find out the max collision number of all buckets; that is, the longest chain length;

With my testing results, I found that Golden Ratio Prime Number always has the fewer empty buckets or zero empty bucket and the shortest collision chain length.

Some hash functions for integers are claimed to be good, but the testing results show that when the total_data_entry / total_bucket_number = 3, the longest chain length is bigger than 10(max collision number > 10), and many buckets are not mapped(empty buckets), which is very bad, compared with the result of zero empty bucket and longest chain length 3 by Golden Ratio Prime Number Hashing.

BTW, with my testing results, I found one version of shifting-xor hash functions is pretty good(It's shared by mikera).

unsigned int Hash_UInt_M3(unsigned int key)
{
  key ^= (key << 13);
  key ^= (key >> 17);    
  key ^= (key << 5); 
  return key;
}

On the replacement side, you must use $1, not \1.

And you can only do what you want by making replace an evalable expression that gives the result you want and telling s/// to eval it with the /ee modifier like so:

$find="start (.*) end";
$replace='"foo $1 bar"';

$var = "start middle end";
$var =~ s/$find/$replace/ee;

print "var: $var\n";

To see why the "" and double /e are needed, see the effect of the double eval here:

$ perl
$foo = "middle";
$replace='"foo $foo bar"';
print eval('$replace'), "\n";
print eval(eval('$replace')), "\n";
__END__
"foo $foo bar"
foo middle bar

(Though as ikegami notes, a single /e or the first /e of a double e isn't really an eval(); rather, it tells the compiler that the substitution is code to compile, not a string. Nonetheless, eval(eval(...)) still demonstrates why you need to do what you need to do to get /ee to work as desired.)

Response.Redirect Response.Redirect() will send you to a new page, update the address bar and add it to the Browser History. On your browser you can click back. It redirects the request to some plain HTML pages on our server or to some other web server. It causes additional roundtrips to the server on each request. It doesn’t preserve Query String and Form Variables from the original request. It enables to see the new redirected URL where it is redirected in the browser (and be able to bookmark it if it’s necessary). Response. Redirect simply sends a message down to the (HTTP 302) browser.

Server.Transfer Server.Transfer() does not change the address bar, we cannot hit back.One should use Server.Transfer() when he/she doesn’t want the user to see where he is going. Sometime on a "loading" type page. It transfers current page request to another .aspx page on the same server. It preserves server resources and avoids the unnecessary roundtrips to the server. It preserves Query String and Form Variables (optionally). It doesn’t show the real URL where it redirects the request in the users Web Browser. Server.Transfer happens without the browser knowing anything, the browser request a page, but the server returns the content of another.

I add credentials for HttpWebRequest.

myReq.UseDefaultCredentials = true;

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

Don't forget to bring your Panel to the Front when dynamically creating it in the form constructor. Example of transparent panel overlay of tab control.

panel1 = new TransparentPanel();
panel1.BackColor = System.Drawing.Color.Transparent;
panel1.Location = new System.Drawing.Point(0, 0);
panel1.Name = "panel1";
panel1.Size = new System.Drawing.Size(717, 92);
panel1.TabIndex = 0;
tab2.Controls.Add(panel1);
panel1.BringToFront(); 

// <== otherwise the other controls paint over top of the transparent panel

It may have been covered elsewhere but simply changing the encoding line of the XML source to 'utf-16' allows the XML to be inserted into a SQL Server 'xml'data type.

using (DataSetTableAdapters.SQSTableAdapter tbl_SQS = new DataSetTableAdapters.SQSTableAdapter())
{
    try
    {
        bodyXML = @"<?xml version="1.0" encoding="UTF-8" standalone="yes"?><test></test>";
        bodyXMLutf16 = bodyXML.Replace("UTF-8", "UTF-16");
        tbl_SQS.Insert(messageID, receiptHandle, md5OfBody, bodyXMLutf16, sourceType);
    }
    catch (System.Data.SqlClient.SqlException ex)
    {
        Console.WriteLine(ex.Message);
        Console.ReadLine();
    }
}

The result is all of the XML text is inserted into the 'xml' data type field but the 'header' line is removed. What you see in the resulting record is just

<test></test>

Using the serialization method described in the "Answered" entry is a way of including the original header in the target field but the result is that the remaining XML text is enclosed in an XML <string></string> tag.

The table adapter in the code is a class automatically built using the Visual Studio 2013 "Add New Data Source: wizard. The five parameters to the Insert method map to fields in a SQL Server table.

We experienced this with SQL Server 2012 / SP3, when running a query via an SqlCommand object from within a C# application. The Command was a simple invocation of a stored procedure having one table parameter; we were passing a list of about 300 integers. The procedure in turn called three user-defined functions and passed the table as a parameter to each of them. The CommandTimeout was set to 90 seconds.

When running precisely the same stored proc with the same argument from within SQL Server Management Studio, the query ran in 15 seconds. But when running it from our application using the above setup, the SqlCommand timed out. The same SqlCommand (with different but comparable data) had been running successfully for weeks, but now it failed with any table argument containing more than 20 or so integers. We did a trace and discovered that when run from the SqlCommand object, the database spent the entire 90 seconds acquiring locks, and would invoke the procedure only at about the moment of the timeout. We changed the CommandTimeout time, and no matter time what we selected the stored proc would be invoked only at the very end of that period. So we surmise that SQL Server was indefinitely acquiring the same locks over and over, and that only the timeout of the Command object caused SQL Server to stop its infinite loop and begin executing the query, by which time it was too late to succeed. A simulation of this same process on a similar server using similar data exhibited no such problem. Our solution was to reboot the entire database server, after which the problem disappeared.

So it appears that there is some problem in SQL Server wherein some resource gets cumulatively consumed and never released. Eventually when connecting via an SqlConnection and running an SqlCommand involving a table parameter, SQL Server goes into an infinite loop acquiring locks. The loop is terminated by the timeout of the SqlCommand object. The solution is to reboot, apparently restoring (temporary?) sanity to SQL Server.

I've created a library with a custom view to solve this issue, and it should be very simple to use. See https://github.com/Comcast/DahDit for more. You can add dashed lines like this:

<com.xfinity.dahdit.DashedLine
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    app:dashHeight="4dp"
    app:dashLength="8dp"
    app:minimumDashGap="3dp"
    app:layout_constraintRight_toRightOf="parent"
    android:id="@+id/horizontal_dashes"/>

Prefixing the statement with an exclamation mark will let you know whether the array is not empty. So in your case -

a = [1,2,3]
!a.empty?
=> true

text and varchar have different implicit type conversions. The biggest impact that I've noticed is handling of trailing spaces. For example ...

select ' '::char = ' '::varchar, ' '::char = ' '::text, ' '::varchar = ' '::text

returns true, false, true and not true, true, true as you might expect.

Suppose you have a Customer Entity mapped to CUSTOMER_INFORMATION table and you want to get list of distinct firstName of customer. You can use below snippet to get the same.

Query distinctFirstName = session.createQuery("select ci.firstName from Customer ci group by ci.firstName");
Object [] firstNamesRows = distinctFirstName.list();

I hope it helps. So here we are using group by instead of using distinct keyword.

Also previously I found it difficult to use distinct keyword when I want to apply it to multiple columns. For example I want of get list of distinct firstName, lastName then group by would simply work. I had difficulty in using distinct in this case.

id is the method you want to use: to convert it to hex:

hex(id(variable_here))

For instance:

x = 4
print hex(id(x))

Gave me:

0x9cf10c

Which is what you want, right?

(Fun fact, binding two variables to the same int may result in the same memory address being used.)
Try:

x = 4
y = 4
w = 9999
v = 9999
a = 12345678
b = 12345678
print hex(id(x))
print hex(id(y))
print hex(id(w))
print hex(id(v))
print hex(id(a))
print hex(id(b))

This gave me identical pairs, even for the large integers.

If you plan on putting the files on a machine supporting only 8.3 naming convention, you should limit the extension to 3 characters.

Otherwise, better choose the more descriptive .html version.

Take a look there : http://developer.android.com/guide/topics/intents/intents-filters.html

DO you have update your manifest file in order to give call rights ?

This is the modified version that I put in my code (I'm using .Net 4.5) but I think it should work on 4.0 too.

public void AppendText(string text, Color color, bool addNewLine = false)
{
        box.SuspendLayout();
        box.SelectionColor = color;
        box.AppendText(addNewLine
            ? $"{text}{Environment.NewLine}"
            : text);
        box.ScrollToCaret();
        box.ResumeLayout();
}

Differences with original one:

• possibility to add text to a new line or simply append it
• no need to change selection, it works the same
• inserted ScrollToCaret to force autoscroll
• added suspend/resume layout calls

The element hasn't been appended yet, therefore it is equal to null. The Id will never = 0. When you call getElementById(id), it is null since it is not a part of the dom yet unless your static id is already on the DOM. Do a call through the console to see what it returns.

For my part I had enabled ufw but I forgot to expose my upstreams ports ._.

If you're using react hooks you have to make sure that data was initialized as an array. Here's is how it must look like:

const[data, setData] = useState([])

import java.util.Scanner;
class my{
public static void main(String args[])
{
    Scanner x=new Scanner(System.in);
    double a,b,c=0,d;
    d=1;
    d=d/10;
    int e,z=0;
    System.out.print("Enter no:");
    a=x.nextInt();

    for(b=1;b<=a/2;b++)
    {
        if(b*b==a)
        {
            c=b;
            break;
        }
        else
        {
            if(b*b>a)
            break;
        }
    } 
    b--;
    if(c==0)
    {
       for(e=1;e<=15;e++)
        {
            while(b*b<=a && z==0)
            {
                if(b*b==a){c=b;z=1;}
                else
                {
                    b=b+d;          //*d==0.1 first time*//
                    if(b*b>=a){z=1;b=b-d;}
                }
            }
            d=d/10;
            z=0;
        }
        c=b;
    }

        System.out.println("Squre root="+c);





}    
}    

Provided you're working in node or a browser with BigInt support, this version cuts costs by saving the expensive string construction for the very end:

const zero = 0n
const shift = 8n

function asciiToBinary (str) {
  const len = str.length
  let n = zero
  for (let i = 0; i < len; i++) {
    n = (n << shift) + BigInt(str.charCodeAt(i))
  }
  return n.toString(2).padStart(len * 8, 0)
}

It's about twice as fast as the other solutions mentioned here including this simple es6+ implementation:

const toBinary = s => [...s]
  .map(x => x
    .codePointAt()
    .toString(2)
    .padStart(8,0)
  )
  .join('')

If you need to handle unicode characters, here's this guy:

const zero = 0n
const shift = 8n
const bigShift = 16n
const byte = 255n

function unicodeToBinary (str) {
  const len = str.length
  let n = zero
  for (let i = 0; i < len; i++) {
    const bits = BigInt(str.codePointAt(i))
    n = (n << (bits > byte ? bigShift : shift)) + bits
  }
  const bin = n.toString(2)
  return bin.padStart(8 * Math.ceil(bin.length / 8), 0)
}

Use

if (Build.VERSION.SDK_INT >= 19) {
        mWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
    }

It should solve the error.

I'm not sure, what you mean as the 'mobile width'. But in each case, the CSS @media can be used for hiding elements in the screen width basis. See some example:

<div id="my-content"></div>

...and:

@media screen and (min-width: 0px) and (max-width: 400px) {
  #my-content { display: block; }  /* show it on small screens */
}

@media screen and (min-width: 401px) and (max-width: 1024px) {
  #my-content { display: none; }   /* hide it elsewhere */
}

Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.

Check your Global.asax.cs file and be sure that this line be there

 AutoMapperConfig.Configure();

Maybe you could use this view, but i'm not sure.

select * from v$database;

But I think It will only show you info about the current db.

Other option, if the db is running in linux... whould be something like this:

SQL>!grep SID $TNS_ADMIN/tnsnames.ora | grep -v PLSExtProc

lblmessage.Text =Request.ServerVariables["REMOTE_HOST"].ToString();

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).

.hero:after,
.hero:after {
    z-index: -1;
    position: absolute;
    top: 98.1%;
    left: calc(50% - 25px);
    content: '';
    width: 0;
    height: 0;
    border-top: solid 50px #e15915;
    border-left: solid 50px transparent;
    border-right: solid 50px transparent;
}

In addition to Alex's answer:

Note that http://server/resource/id?force_delete=true identifies a different resource than http://server/resource/id. For example, it is a huge difference whether you delete /customers/?status=old or /customers/.

In React Native , This worked for me

name = "hi \n\ruser"
name.replace( /[\r\n]+/gm, ""); // hi user

The general approach to this is to:

1. Get the time at the start of your benchmark, say at the start of main().
2. Run your code.
3. Get the time at the end of your benchmark, say at the end of main().
4. Subtract the start time from the end time and convert into appropriate units.

A hint: look at System.nanoTime() or System.currentTimeMillis().

Here is my approach, clunky as it is and available in github:

Put in the very first notebook cell, the import cell:

from IPythonTOC import IPythonTOC

toc = IPythonTOC()

Somewhere after the import cell, put in the genTOCEntry cell but don't run it yet:

''' if you called toc.genTOCMarkdownCell before running this cell, 
the title has been set in the class '''

print toc.genTOCEntry()

Below the genTOCEntry cell`, make a TOC cell as a markdown cell:

<a id='TOC'></a>

#TOC

As the notebook is developed, put this genTOCMarkdownCell before starting a new section:

with open('TOCMarkdownCell.txt', 'w') as outfile:

    outfile.write(toc.genTOCMarkdownCell('Introduction'))

!cat TOCMarkdownCell.txt

!rm TOCMarkdownCell.txt

Move the genTOCMarkdownCell down to the point in your notebook where you want to start a new section and make the argument to genTOCMarkdownCell the string title for your new section then run it. Add a markdown cell right after it and copy the output from genTOCMarkdownCell into the markdown cell that starts your new section. Then go to the genTOCEntry cell near the top of your notebook and run it. For example, if you make the argument to genTOCMarkdownCell as shown above and run it, you get this output to paste into the first markdown cell of your newly indexed section:

<a id='Introduction'></a>

###Introduction

Then when you go to the top of your notebook and run genTocEntry, you get the output:

[Introduction](#Introduction)

Copy this link string and paste it into the TOC markdown cell as follows:

<a id='TOC'></a>

#TOC

[Introduction](#Introduction)

After you edit the TOC cell to insert the link string and then you press shift-enter, the link to your new section will appear in your notebook Table of Contents as a web link and clicking it will position the browser to your new section.

One thing I often forget is that clicking a line in the TOC makes the browser jump to that cell but doesn't select it. Whatever cell was active when we clicked on the TOC link is still active, so a down or up arrow or shift-enter refers to still active cell, not the cell we got by clicking on the TOC link.

While some of those code-snippets are short and working, they aren't trivial to follow and understand.

As i am not a fan of "copy-paste" from stack-overflow, i would like developers to understand the code they are push into they software, hope you'll find the below useful.

DEMO: Resizing images with JS and HTML Canvas Demo fiddler.

You may find 3 different methods to do this resize, that will help you understand how the code is working and why.

https://jsfiddle.net/1b68eLdr/93089/

Full code of both demo, and TypeScript method that you may want to use in your code, can be found in the GitHub project.

https://github.com/eyalc4/ts-image-resizer

This is the final code:

export class ImageTools {
base64ResizedImage: string = null;

constructor() {
}

ResizeImage(base64image: string, width: number = 1080, height: number = 1080) {
    let img = new Image();
    img.src = base64image;

    img.onload = () => {

        // Check if the image require resize at all
        if(img.height <= height && img.width <= width) {
            this.base64ResizedImage = base64image;

            // TODO: Call method to do something with the resize image
        }
        else {
            // Make sure the width and height preserve the original aspect ratio and adjust if needed
            if(img.height > img.width) {
                width = Math.floor(height * (img.width / img.height));
            }
            else {
                height = Math.floor(width * (img.height / img.width));
            }

            let resizingCanvas: HTMLCanvasElement = document.createElement('canvas');
            let resizingCanvasContext = resizingCanvas.getContext("2d");

            // Start with original image size
            resizingCanvas.width = img.width;
            resizingCanvas.height = img.height;


            // Draw the original image on the (temp) resizing canvas
            resizingCanvasContext.drawImage(img, 0, 0, resizingCanvas.width, resizingCanvas.height);

            let curImageDimensions = {
                width: Math.floor(img.width),
                height: Math.floor(img.height)
            };

            let halfImageDimensions = {
                width: null,
                height: null
            };

            // Quickly reduce the dize by 50% each time in few iterations until the size is less then
            // 2x time the target size - the motivation for it, is to reduce the aliasing that would have been
            // created with direct reduction of very big image to small image
            while (curImageDimensions.width * 0.5 > width) {
                // Reduce the resizing canvas by half and refresh the image
                halfImageDimensions.width = Math.floor(curImageDimensions.width * 0.5);
                halfImageDimensions.height = Math.floor(curImageDimensions.height * 0.5);

                resizingCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                    0, 0, halfImageDimensions.width, halfImageDimensions.height);

                curImageDimensions.width = halfImageDimensions.width;
                curImageDimensions.height = halfImageDimensions.height;
            }

            // Now do final resize for the resizingCanvas to meet the dimension requirments
            // directly to the output canvas, that will output the final image
            let outputCanvas: HTMLCanvasElement = document.createElement('canvas');
            let outputCanvasContext = outputCanvas.getContext("2d");

            outputCanvas.width = width;
            outputCanvas.height = height;

            outputCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                0, 0, width, height);

            // output the canvas pixels as an image. params: format, quality
            this.base64ResizedImage = outputCanvas.toDataURL('image/jpeg', 0.85);

            // TODO: Call method to do something with the resize image
        }
    };
}}

Or File::Find

use File::Find;
finddepth(\&wanted, '/some/path/to/dir');
sub wanted { print };

It'll go through subdirectories if they exist.

I'm just returning to this question after taking sth's answer and making a small but very useful modification. This function prints all keys in the JSON tree as well as the size of leaf nodes in that tree.

def print_JSON_tree(d, indent=0):
    for key, value in d.iteritems():
        print '    ' * indent + unicode(key),
        if isinstance(value, dict):
            print; print_JSON_tree(value, indent+1)
        else:
            print ":", str(type(d[key])).split("'")[1], "-", str(len(unicode(d[key])))

It's really nice when you have large JSON objects and want to figure out where the meat is. Example:

>>> print_JSON_tree(JSON_object)
key1
    value1 : int - 5
    value2 : str - 16
    key2
       value1 : str - 34
       value2 : list - 5623456

This would tell you that most of the data you care about is probably inside JSON_object['key1']['key2']['value2'] because the length of that value formatted as a string is very large.

One option is to use the delete method as follows:

StringBuffer sb = new StringBuffer();
for (int n = 0; n < 10; n++) {
   sb.append("a");

   // This will clear the buffer
   sb.delete(0, sb.length());
}

Another option (bit cleaner) uses setLength(int len):

sb.setLength(0);

See Javadoc for more info:

I was having a similar issue with formatting CardViews in a recylerView.

I got this simple solution working, not sure if it's the best solution, but it worked for me.

mv_cardView.getBackground().setTint(Color.BLUE)

It gets the background Drawable of the cardView and tints it.

Works for me on a mysql database also:

Entity\Entity_name:
    type: entity
    table: table_name
    fields: 
        field_name:
            type: integer
            nullable: true
            options:
                default: 1

The accepted answer works great, but the resize logic ignores the case in which the image is larger than the maximum in only one of the axes (for example, height > maxHeight but width <= maxWidth).

I think the following code takes care of all cases in a more straight-forward and functional way (ignore the typescript type annotations if using plain javascript):

private scaleDownSize(width: number, height: number, maxWidth: number, maxHeight: number): {width: number, height: number} {
    if (width <= maxWidth && height <= maxHeight)
      return { width, height };
    else if (width / maxWidth > height / maxHeight)
      return { width: maxWidth, height: height * maxWidth / width};
    else
      return { width: width * maxHeight / height, height: maxHeight };
  }

Here's my solution. It seems to be dumb but works well...and I was trying to find all proper divisors so the loop started from i = 2.

import math as m 

def findfac(n):
    faclist = [1]
    for i in range(2, int(m.sqrt(n) + 2)):
        if n%i == 0:
            if i not in faclist:
                faclist.append(i)
                if n/i not in faclist:
                    faclist.append(n/i)
    return facts

• return returns from the current function; it's a language keyword like for or break.
• exit() terminates the whole program, wherever you call it from. (After flushing stdio buffers and so on).

The only case when both do (nearly) the same thing is in the main() function, as a return from main performs an exit().

In most C implementations, main is a real function called by some startup code that does something like int ret = main(argc, argv); exit(ret);. The C standard guarantees that something equivalent to this happens if main returns, however the implementation handles it.

Example with return:

#include <stdio.h>

void f(){
    printf("Executing f\n");
    return;
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f
Back from f

Another example for exit():

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

void f(){
    printf("Executing f\n");
    exit(0);
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f

You never get "Back from f". Also notice the #include <stdlib.h> necessary to call the library function exit().

Also notice that the parameter of exit() is an integer (it's the return status of the process that the launcher process can get; the conventional usage is 0 for success or any other value for an error).

The parameter of the return statement is whatever the return type of the function is. If the function returns void, you can omit the return at the end of the function.

Last point, exit() come in two flavors _exit() and exit(). The difference between the forms is that exit() (and return from main) calls functions registered using atexit() or on_exit() before really terminating the process while _exit() (from #include <unistd.h>, or its synonymous _Exit from #include <stdlib.h>) terminates the process immediately.

Now there are also issues that are specific to C++.

C++ performs much more work than C when it is exiting from functions (return-ing). Specifically it calls destructors of local objects going out of scope. In most cases programmers won't care much of the state of a program after the processus stopped, hence it wouldn't make much difference: allocated memory will be freed, file ressource closed and so on. But it may matter if your destructor performs IOs. For instance automatic C++ OStream locally created won't be flushed on a call to exit and you may lose some unflushed data (on the other hand static OStream will be flushed).

This won't happen if you are using the good old C FILE* streams. These will be flushed on exit(). Actually, the rule is the same that for registered exit functions, FILE* will be flushed on all normal terminations, which includes exit(), but not calls to _exit() or abort().

You should also keep in mind that C++ provide a third way to get out of a function: throwing an exception. This way of going out of a function will call destructor. If it is not catched anywhere in the chain of callers, the exception can go up to the main() function and terminate the process.

Destructors of static C++ objects (globals) will be called if you call either return from main() or exit() anywhere in your program. They wont be called if the program is terminated using _exit() or abort(). abort() is mostly useful in debug mode with the purpose to immediately stop the program and get a stack trace (for post mortem analysis). It is usually hidden behind the assert() macro only active in debug mode.

When is exit() useful ?

exit() means you want to immediately stops the current process. It can be of some use for error management when we encounter some kind of irrecoverable issue that won't allow for your code to do anything useful anymore. It is often handy when the control flow is complicated and error codes has to be propagated all way up. But be aware that this is bad coding practice. Silently ending the process is in most case the worse behavior and actual error management should be preferred (or in C++ using exceptions).

Direct calls to exit() are especially bad if done in libraries as it will doom the library user and it should be a library user's choice to implement some kind of error recovery or not. If you want an example of why calling exit() from a library is bad, it leads for instance people to ask this question.

There is an undisputed legitimate use of exit() as the way to end a child process started by fork() on Operating Systems supporting it. Going back to the code before fork() is usually a bad idea. This is the rationale explaining why functions of the exec() family will never return to the caller.

Following @armod's update about exceptions being added right on client objects. I'll show how you can see all exceptions defined for your client class.

Exceptions are generated dynamically when you create your client with session.create_client() or boto3.client(). Internally it calls method botocore.errorfactory.ClientExceptionsFactory._create_client_exceptions() and fills client.exceptions field with constructed exception classes.

All class names are available in client.exceptions._code_to_exception dictionary, so you can list all types with following snippet:

client = boto3.client('s3')

for ex_code in client.exceptions._code_to_exception:
    print(ex_code)

Hope it helps.

Here is the sh for last used simulator and application. Just run sh and copy printed text and paste and run command for show in finder.

If you created a file inside a new directory, instead of 'svn add newdir/newfile' use 'svn add newdir' because you need to add the directory. All the files inside the directory will be added by default.

This should work for you. Infact the one which you are thinking will also work:-

 DECLARE @returnvalue INT

 EXEC @returnvalue = SP_One

6. Apply and save it
7. Now resave the code in the bin folder in developer c

The order of items in the PATH matters. If there are multiple entries for various java installations, the first one in your PATH will be used.

I have had similar issues after installing a product, like Oracle, that puts it's JRE at the beginning of the PATH.

Ensure that the JDK you want to be loaded is the first entry in your PATH (or at least that it appears before C:\Program Files\Java\jre6\bin appears).

Just in case you have a preference for how negative numbers are formatted:

p "%x" % -1   #=> "..f"
p -1.to_s(16) #=> "-1"

Avoid the Date object creation w/ System.currentTimeMillis(). A divide by 1000 gets you to Unix epoch.

As mentioned in a comment, you typically want a primitive long (lower-case-l long) not a boxed object long (capital-L Long) for the unixTime variable's type.

long unixTime = System.currentTimeMillis() / 1000L;

If your emulator x86 this method works your me.

Update for latest SDK:

Now @zeuter's answer is correct for Facebook SDK v4.7+:

Original answer:

Please do not use SessionTracker. It is an internal (package private) class, and is not meant to be consumed as part of the public API. As such, its API may change at any time without any backwards compatibility guarantees. You should be able to get rid of all instances of SessionTracker in your code, and just use the active session instead.

To answer your question, if you don't want to keep any session data, simply call closeAndClearTokenInformation when your app closes.

There should be one - and preferably only one - obvious way to do it.

Therefore list(dictionary.values()) is the one way.

Yet, considering Python3, what is quicker?

[*L] vs. [].extend(L) vs. list(L)

I would prefer CTE for deleting duplicate rows from sql server table

strongly recommend to follow this article ::http://codaffection.com/sql-server-article/delete-duplicate-rows-in-sql-server/

by keeping original

WITH CTE AS
(
SELECT *,ROW_NUMBER() OVER (PARTITION BY col1,col2,col3 ORDER BY col1,col2,col3) AS RN
FROM MyTable
)

DELETE FROM CTE WHERE RN<>1

without keeping original

WITH CTE AS
(SELECT *,R=RANK() OVER (ORDER BY col1,col2,col3)
FROM MyTable)
 
DELETE CTE
WHERE R IN (SELECT R FROM CTE GROUP BY R HAVING COUNT(*)>1)

what you were trying to do with the curl command was to download the file to your local hard drive(HD). You however need to specify a path on HD

curl http://example.com/passkey=wedsmdjsjmdd -o ./example.csv
cr = csv.reader(open('./example.csv',"r"))
for row in cr:
    print row

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

This worked me perfectly....

NSNumber *value = [NSNumber numberWithInt:UIDeviceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:@"orientation"];

For me @pvskisteak5 answer has caused a "flicker-effect". To fix this, add the following:

            .table-hover tbody tr:hover,
            .table-hover tbody tr:hover td,
            .table-hover tbody tr:hover th{
                background:#22313F !important;
                color:#fff !important;
            }

ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable("COLOR")); 

it worked for me here

Fundamentally, in C, "types" are a way to interpret bytes in memory. For example, what the following code

struct Point {
  int x;
  int y;
};

int main() {
  struct Point p;
  p.x = 0;
  p.y = 0;
}

Says "When I run main, I want to allocate 4 (size of integer) + 4 (size of integer) = 8 (total bytes) of memory. When I write '.x' as a lvalue on a value with the type label Point at compile time, retrieve data from the pointer's memory location plus four bytes. Give the return value the compile-time label "int.""

Inside the computer at runtime, your "Point" structure looks like this:

00000000 00000000 00000000 00000000 00000000 00000000 00000000

And here's what your void* data type might look like: (assuming a 32-bit computer)

10001010 11111001 00010010 11000101

The best solution to this in my opinion is this:

1. Create a custom filter which can be in a common.module.js file for example - used through out your app:

   var app = angular.module('common.module', []);
   
   // html filter (render text as html)
   app.filter('html', ['$sce', function ($sce) { 
       return function (text) {
           return $sce.trustAsHtml(text);
       };    
   }])
   

2. Usage:

   <span ng-bind-html="yourDataValue | html"></span>
   

Now - I don't see why the directive ng-bind-html does not trustAsHtml as part of its function - seems a bit daft to me that it doesn't

Anyway - that's the way I do it - 67% of the time, it works ever time.

In my situation, --prefix= failed to update the path correctly under some warnings or failures. please see the below link for the answer. https://stackoverflow.com/a/50208379/1283198

I don't think that the hasEventListener plugin mentioned will handle custom events e.g.

var obj = {id:'test'};
$(obj).bind('custom', function(){
    alert('custom');
}).trigger('custom');

alert($(obj).hasEventListener('custom'));

Also, at least in jQuery 1.5 I think you need to be careful using $(target).data('events') because it returns differently for events that have been bound to objects as above.

You need to do something like:

var events = $(target).data("events");
if(typeof events === "function"){
   events = events.events;
}

I am using this sort of approach and it works but it feels a bit like I am at the mercy of jquery internals and that really I shouldn't be doing it!

You can use the following CSS to solve.

ul li { float: left; }
ul li:before { content: "|"; padding: 0 .5em; }
ul li:first-child:before { content: ""; padding: 0; }

Should work on IE8+ as well.

For 8085: Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address of the top of the stack.

The stack pointer register in a computer is made available for general purpose use by programs executing at lower privilege levels than interrupt handlers. A set of instructions in such programs, excluding stack operations, stores data other than the stack pointer, such as operands, and the like, in the stack pointer register. When switching execution to an interrupt handler on an interrupt, return address data for the currently executing program is pushed onto a stack at the interrupt handler's privilege level. Thus, storing other data in the stack pointer register does not result in stack corruption. Also, these instructions can store data in a scratch portion of a stack segment beyond the current stack pointer.

Read this one for more info.

General purpose use of a stack pointer register

From Tomcat documentation, For blocking I/O (BIO), the default value of maxConnections is the value of maxThreads unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads.

I would suggest a two step query

I'm assuming you have an autoincrementing primary key because you say your PK is (max+1) which sounds like the definition of an autioincrementing key.
I'm calling the PK id, substitute with whatever your PK is called.

1 - figure out the primary key number for column 1000.

SELECT @id:= id FROM smartmeter_usage LIMIT 1 OFFSET 1000

2 - update the table.

UPDATE smartmeter_usage.users_reporting SET panel_id = 3 
WHERE panel_id IS NULL AND id >= @id 
ORDER BY id 
LIMIT 1000

Please test to see if I didn't make an off-by-one error; you may need to add or subtract 1 somewhere.

There are three "vanilla" ways to check this with or without jQuery.

1. First is to force boolean evaluation by coercion, then check if it's equal to the original value:

   function isBoolean( n ) {
       return !!n === n;
   }
   

2. Doing a simple typeof check:

   function isBoolean( n ) {
       return typeof n === 'boolean';
   }
   

3. Doing a completely overkill and unnecessary instantiation of a class wrapper on a primative:

   function isBoolean( n ) {
       return n instanceof Boolean;
   }
   

The third will only return true if you create a new Boolean class and pass that in.

To elaborate on primitives coercion (as shown in #1), all primitives types can be checked in this way:

• Boolean:

  function isBoolean( n ) {
      return !!n === n;
  }
  

• Number:

  function isNumber( n ) {
      return +n === n;
  }
  

• String:

  function isString( n ) {
      return ''+n === n;
  }
  

Does:

Set Sheets("Output").Range("$A$1:$A$500") =  Sheets(sheet_).Range("$A$1:$A$500")

...work? (I don't have Excel in front of me, so can't test.)

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).

Sort each element then look for duplicates. There's a built-in function for sorting so you do not need to import anything

You can use jquery

HTML file

<input id="email" name="email">

jquery code

$('#email').bind('copy paste', function (e) {
        e.preventDefault();
    });

gcc by default does not inline any functions when compiling without optimization enabled. I don't know about visual studio – deft_code

I checked this for Visual Studio 9 (15.00.30729.01) by compiling with /FAcs and looking at the assembly code: The compiler produced calls to member functions without optimization enabled in debug mode. Even if the function is marked with __forceinline, no inline runtime code is produced.

check this Twig Reference.

You can do it that simple:

{% if (a or b) %}
    ...
{% endif %}

You can undo a rails generate in the following ways:

• For the model: rails destroy MODEL
• For the controller: rails destroy controller_name

Code example is given on the author site's. You can use babelfish to translate the texts (Japanese to English).

As far as I understand Japanese, this zip inflate code is meant to decode ZIP data (streams) not ZIP archive.

Try using this:

$('#searchField').val('');

I went back to jquery-2.2.4.min.js and it works.

Long and long int are at least 32 bits.

long long and long long int are at least 64 bits. You must be using a c99 compiler or better.

long doubles are a bit odd. Look them up on Wikipedia for details.

<style>
.form-error {
        border: 2px solid #e74c3c;
    }
</style>



<div class="form-error">
                                {!! Form::select('color', $colors->prepend('Please Select Color', ''),           ,['class' => 'form-control dropselect form-error'
                                ,'tabindex' => $count++, 'id' => 'color']) !!}
                                </div>

If you include all files of *.js in directory example ("app/lib/*.js"):

In directory app/lib

example.js:

module.exports = function (example) { }

example-2.js:

module.exports = function (example2) { }

In directory app create index.js

index.js:

module.exports = require('./app/lib');

io.js has an exit and a beforeExit event, which do what you want.

If you have

@Transactional // Spring Transactional
class MyDao extends Dao {
}

and super-class

class Dao {
    public void save(Entity entity) { getEntityManager().merge(entity); }
}

and you call

@Autowired MyDao myDao;
myDao.save(entity);

you won't get a Spring TransactionInterceptor (that gives you a transaction).

This is what you need to do:

@Transactional 
class MyDao extends Dao {
    public void save(Entity entity) { super.save(entity); }
}

Unbelievable but true.

Your example Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: ["foo": "bar"]) already contains "foo=bar" string as its body. But if you really want string with custom format. You can do this:

Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: [:], encoding: .Custom({
            (convertible, params) in
            var mutableRequest = convertible.URLRequest.copy() as NSMutableURLRequest
            mutableRequest.HTTPBody = "myBodyString".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
            return (mutableRequest, nil)
        }))

Note: parameters should not be nil

UPDATE (Alamofire 4.0, Swift 3.0):

In Alamofire 4.0 API has changed. So for custom encoding we need value/object which conforms to ParameterEncoding protocol.

extension String: ParameterEncoding {

    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var request = try urlRequest.asURLRequest()
        request.httpBody = data(using: .utf8, allowLossyConversion: false)
        return request
    }

}

Alamofire.request("http://mywebsite.com/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])

The way to run all of logrotate is:

logrotate -f /etc/logrotate.conf

that will run the primary logrotate file, which includes the other logrotate configurations as well

I found this page 10 years (!) after the original post, and needed the answer as vanilla js instead of AJAX. I figured it out with the help of @gargAman's answer.

Use an appropriate selector to assign your button to a variable, e.g.

document.getElementById('myButton')

then

myButton.addEventListener('click', function(e) {
    e.preventDefault();
    // do cool stuff
});

I should note that my html looks like this (specifically, I am not using type="Submit" in my button and action="" in my form:

  <form method="POST" action="" id="myForm">
    <!-- form fields -->
    <button id="myButton" class="btn-submit">Submit</button>
  </form>

Yet another option uses structs:

struct func_opts {
  int    arg1;
  char * arg2;
  int    arg3;
};

void func(int arg, struct func_opts *opts)
{
    int arg1 = 0, arg3 = 0;
    char *arg2 = "Default";
    if(opts)
      {
        if(opts->arg1)
            arg1 = opts->arg1;
        if(opts->arg2)
            arg2 = opts->arg2;
        if(opts->arg3)
            arg3 = opts->arg3;
      }
    // do stuff
}

// call with defaults
func(3, NULL);

// also call with defaults
struct func_opts opts = {0};
func(3, &opts);

// set some arguments
opts.arg3 = 3;
opts.arg2 = "Yes";
func(3, &opts);

Refer to here

write query with named parameter, use simple ListPreparedStatementSetter with all parameters in sequence. Just add below snippet to convert the query in traditional form based to available parameters,

ParsedSql parsedSql = NamedParameterUtils.parseSqlStatement(namedSql);

List<Integer> parameters = new ArrayList<Integer>();
for (A a : paramBeans)
    parameters.add(a.getId());

MapSqlParameterSource parameterSource = new MapSqlParameterSource();
parameterSource.addValue("placeholder1", parameters);
// create SQL with ?'s
String sql = NamedParameterUtils.substituteNamedParameters(parsedSql, parameterSource);     
return sql;

Try this

div:nth-child(4n+4)

One way is to get system properties that give you the path separator for the operating system, this tutorial explains how. You can then use a standard string join using the file.separator.

How about this? Here, pElement refers to the element you want this div inside (to be a child of! :).

$("pElement").append("<div></div");

You can easily add anything more to that div in the string - Attributes, Content, you name it. Do note, for attribute values, you need to use the right quotation marks.

Additionally if you need to restrict the grouping you can use:

db.events.aggregate( 
    {$match: {province: "ON"}},
    {$group: {_id: "$date", number: {$sum: 1}}}  
)

DELETE FROM ... WHERE id=...;

protected function templateRemove($id){
            $em = $this->getDoctrine()->getManager();
            $entity = $em->getRepository('XXXBundle:Templates')->findOneBy(array('id' => $id));

            if ($entity != null){
                $em->remove($entity);
                $em->flush();
            }
        }

From this answer:

[HttpPost]
public void Confirmation(HttpRequestMessage request)
{
    var content = request.Content;
    string jsonContent = content.ReadAsStringAsync().Result;
}

Note: As seen in the comments, this code could cause a deadlock and should not be used. See this blog post for more detail.

A space is legal in file names. If you put your path and file name in quotes, it may just fly. Here's what I'm using in a batch file:

svnadmin hotcopy "C:\SourcePath\Folder" "f:\DestPath\Folder%filename%"

It doesn't matter if there are spaces in %filename%.

I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:

  JButton button = new JButton();
  try {
    Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));
    button.setIcon(new ImageIcon(img));
  } catch (Exception ex) {
    System.out.println(ex);
  }

In this example, it is assumed that image is in src/resources/ folder.

You can also try the following project that aims to help use that api. It's here:https://github.com/MathiasSeguy-Android2EE/GDirectionsApiUtils

How it works, definitly simply:

public class MainActivity extends ActionBarActivity implements DCACallBack{
/**
 * Get the Google Direction between mDevice location and the touched location using the     Walk
 * @param point
 */
private void getDirections(LatLng point) {
     GDirectionsApiUtils.getDirection(this, mDeviceLatlong, point,     GDirectionsApiUtils.MODE_WALKING);
}

/*
 * The callback
 * When the direction is built from the google server and parsed, this method is called and give you the expected direction
 */
@Override
public void onDirectionLoaded(List<GDirection> directions) {        
    // Display the direction or use the DirectionsApiUtils
    for(GDirection direction:directions) {
        Log.e("MainActivity", "onDirectionLoaded : Draw GDirections Called with path " + directions);
        GDirectionsApiUtils.drawGDirection(direction, mMap);
    }
}

<script>
var someSession = '<%= Session["SessionName"].ToString() %>';
alert(someSession)
</script>

This code you can write in Aspx. If you want this in some js.file, you have two ways:

1. Make aspx file which writes complete JS code, and set source of this file as Script src
2. Make handler, to process JS file as aspx.

You can't use it in the way you describe. The point about generic types, is that although you may not know them at "coding time", the compiler needs to be able to resolve them at compile time. Why? Because under the hood, the compiler will go away and create a new type (sometimes called a closed generic type) for each different usage of the "open" generic type.

In other words, after compilation,

DoesEntityExist<int>

is a different type to

DoesEntityExist<string>

This is how the compiler is able to enfore compile-time type safety.

For the scenario you describe, you should pass the type as an argument that can be examined at run time.

The other option, as mentioned in other answers, is that of using reflection to create the closed type from the open type, although this is probably recommended in anything other than extreme niche scenarios I'd say.

The sexiest version by far is with format strings.

from datetime import datetime

print(f'{datetime.today():%Y-%m-%d}')

Yes, You can use gcc to compile your asm code. Use -c for compilation like this:

gcc -c file.S -o file.o

This will give object code file named file.o. To invoke linker perform following after above command:

gcc file.o -o file

First, have you compiled the class using the command line javac compiler? Second, it seems that your main method has an incorrect signature - it should be taking in an array of String objects, rather than just one:

public static void main(String[] args){

Once you've changed your code to take in an array of String objects, then you need to make sure that you're printing an element of the array, rather than array itself:

System.out.println(args[0])

If you want to print the whole list of command line arguments, you'd need to use a loop, e.g.

for(int i = 0; i < args.length; i++){
    System.out.print(args[i]);
}
System.out.println();

in Project window right click on your project and select properties go to Run and set Main Class ( you can brows it) . this manual work if you have static main in some class :

public class Someclass
{

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        //your code
    }
}

Netbeans doesn't have any conflict with W7 and you can use version 6.8 .

You could add the time component

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

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

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

If you are using gradle you can just add this to your build.gradle

springBoot {
    executable = true
}

You can then run your application by typing ./your-app.jar

Also, you can find a complete guide here to set up your app as a service

Integer.parseInt(myString.replaceFirst("#", ""), 16) 

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

You can use Files#readAllLines() to get all lines of a text file into a List<String>.

for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    // ...
}

Tutorial: Basic I/O > File I/O > Reading, Writing and Creating text files

You can use String#split() to split a String in parts based on a regular expression.

for (String part : line.split("\\s+")) {
    // ...
}

Tutorial: Numbers and Strings > Strings > Manipulating Characters in a String

You can use Integer#valueOf() to convert a String into an Integer.

Integer i = Integer.valueOf(part);

Tutorial: Numbers and Strings > Strings > Converting between Numbers and Strings

You can use List#add() to add an element to a List.

numbers.add(i);

Tutorial: Interfaces > The List Interface

So, in a nutshell (assuming that the file doesn't have empty lines nor trailing/leading whitespace).

List<Integer> numbers = new ArrayList<>();
for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    for (String part : line.split("\\s+")) {
        Integer i = Integer.valueOf(part);
        numbers.add(i);
    }
}

If you happen to be at Java 8 already, then you can even use Stream API for this, starting with Files#lines().

List<Integer> numbers = Files.lines(Paths.get("/path/to/test.txt"))
    .map(line -> line.split("\\s+")).flatMap(Arrays::stream)
    .map(Integer::valueOf)
    .collect(Collectors.toList());

In Xcode 8 and iOS 10 to determine the height of a web view. you can get height using

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    CGFloat height = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.scrollHeight"] floatValue];
    NSLog(@"Webview height is:: %f", height);
}

OR for Swift

 func webViewDidFinishLoad(aWebView:UIWebView){
        let height: Float = (aWebView.stringByEvaluatingJavaScriptFromString("document.body.scrollHeight")?.toFloat())!
        print("Webview height is::\(height)")
    }

Windows : ctrl + F12

MacOS : cmd + F12

Above commands will show the functions/methods in the current class.

Press SHIFT TWO times if you want to search both class and method in the whole project.

In addition to Tim's answer, this issue occurred for me when I was splitting up a refactoring a file, splitting it up into their own files.

VSCode, for some reason, indented parts of my [class] code, which caused this issue. This was hard to notice at first, but after I realised the code was indented, I formatted the code and the issue disappeared.

for example, everything after the first line of the Class definition was auto-indented during the paste.

export class MyClass extends Something<string> {
    public blah: string = null;

    constructor() { ... }
  }

Here is the easiest way I use, hope works for you,

var1 = var1 or 4

This assigns 4 to var1 only if var1 is None , False or 0

Yeah, it is quite vague.

You should use it whenever for readers of the documentation of your method it may be useful to also look at some other method. If the documentation of your methodA says "Works like methodB but ...", then you surely should put a link. An alternative to @see would be the inline {@link ...} tag:

/**
 * ...
 * Works like {@link #methodB}, but ...
 */

When the fact that methodA calls methodB is an implementation detail and there is no real relation from the outside, you don't need a link here.

This usually happens for me if I compiled the project in Visual Studio 2017 & then I try to rebuild & run it with .NET Core with the command line command "dotnet run".

Simply deleting all the "bin" & "obj" folders - both inside "ClientApp" & directly in the project folder - allowed the .NET Core command "dotnet run" to rebuild & run successfully.

I have had a difficulty with the EF when the connection the server is stopped or paused, and I raised the same question. So for completeness to the above answers here is the code.

/// <returns>true if the connection is opened</returns>
private static bool IsServerConnected(string connectionString)

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        try
        {
            connection.Open();
            return true;
        }
        catch (SqlException)
        {
            return false;
        }

The Maven Help Plugin is somehow already proposing something for this:

In SQL without SELECT you cannot result anything. Instead of IF-ELSE block I prefer to use CASE statement for this

SELECT CASE
         WHEN EXISTS (SELECT 1
                      FROM   tblGLUserAccess
                      WHERE  GLUserName = 'xxxxxxxx') THEN 1
         ELSE 2
       END 

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

A much easier way is to go to Data and select Group or Subtotal. Instant collapsible rows without messing with pivot tables or VBA.

ALTER TABLE MEN DROP COLUMN Lname

    int x=550;
    string s=" ";
    string y=" ";

    while (x>0)
    {

        s += x%2;
        x=x/2;
    }


    Console.WriteLine(Reverse(s));
}

public static string Reverse( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse( charArray );
    return new string( charArray );
}

This is what I've been doing if you need to do something iterative... but it would be wise to look for set operations first. Also, do not do this because you don't want to learn cursors.

select top 1000 TableID
into #ControlTable 
from dbo.table
where StatusID = 7

declare @TableID int

while exists (select * from #ControlTable)
begin

    select top 1 @TableID = TableID
    from #ControlTable
    order by TableID asc

    -- Do something with your TableID

    delete #ControlTable
    where TableID = @TableID

end

drop table #ControlTable

In my case it was due to adding requireSSL=true to httpcookies in webconfig which made the AntiForgeryToken stop working. Example:

<system.web>
  <httpCookies httpOnlyCookies="true" requireSSL="true"/>
</system.web>

To make both requireSSL=true and @Html.AntiForgeryToken() work I added this line inside the Application_BeginRequest in Global.asax

    protected void Application_BeginRequest(object sender, EventArgs e)
  {
    AntiForgeryConfig.RequireSsl = HttpContext.Current.Request.IsSecureConnection;
  }

You can take a look at stagemonitor. It is a open source java (web) application performance monitor. It captures response time metrics, JVM metrics, request details (including a call stack captured by the request profiler) and more. The overhead is very low.

Optionally, you can use the great timeseries database graphite with it to store a long history of datapoints that you can look at with fancy dashboards.

Example:

Take a look at the project website to see screenshots, feature descriptions and documentation.

Note: I am the developer of stagemonitor

https://github.com/JamesHeinrich/getID3 download getid3 zip and than only getid3 named folder copy paste in project folder and use it as below show...

<?php
        require_once('/fire/scripts/lib/getid3/getid3/getid3.php');
        $getID3 = new getID3();
        $filename="/fire/My Documents/video/ferrari1.mpg";
        $fileinfo = $getID3->analyze($filename);

        $width=$fileinfo['video']['resolution_x'];
        $height=$fileinfo['video']['resolution_y'];

        echo $fileinfo['video']['resolution_x']. 'x'. $fileinfo['video']['resolution_y'];
        echo '<pre>';print_r($fileinfo);echo '</pre>';
?>

The -> operator, which is applied exclusively to pointers, is needed to obtain the specified field or method of the object referenced by the pointer. (this applies also to structs just for their fields)

If you have a variable ptr declared as a pointer you can think of it as (*ptr).field.

A side node that I add just to make pedantic people happy: AS ALMOST EVERY OPERATOR you can define a different semantic of the operator by overloading it for your classes.

Wonder why nobody said it here earlier: to prevent <a href="#"> from scrolling document position to the top, simply use <a href="#/"> instead. That's mere HTML, no JQuery needed. Using event.preventDefault(); is just too much!

Line endings also called newline, end of line (EOL) or line break is a control character or sequence of control characters in a character encoding specification (e.g. ASCII or EBCDIC) that is used to signify the end of a line of text and the start of a new one. Some text editors set/implement this special character when you press the Enter key.

The Carriage Return, Line Feed characters are ASCII representations for the end of a line (EOL). They will end the current line of a string, and start a new one.

However, at the operating system level, they are treated differently:

• The Carriage Return ("CR") character (ASCII 13\0x0D, \r): Moves the cursor to the beginning of the line without advancing to the next line. This character is used as the new line character in Commodore and Early Macintosh operating systems (Mac OS 9 and earlier).

• The Line Feed ("LF") character (ASCII 10\0x0A, \n): Moves the cursor down to the next line without returning to the beginning of the line. This character is used as the new line character in Unix based systems (Linux, macOS X, Android, etc).

• The Carriage Return Line Feed ("CRLF") character (0x0D0A, \r\n): This is actually two ASCII characters and is a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as the new line character in most other non-Unix operating systems, including Microsoft Windows and Symbian OS.

Normalizing inconsistent line endings in Visual Studio means selecting one character type to be used for all your files. It could be:

• The Carriage Return Line Feed ("CRLF") character
• The Line Feed ("LF") character
• The Carriage Return ("CR") character

However, you can set this in a better way using .gitattributes file in your root directory to avoid conflicts when you move your files from one Operating system to the other.

Simply create a new file called .gitattributes in the root directory of your application:

touch .gitattributes

And add the following in it:

# Enforce Unix newlines
* text=auto eol=lf

This enforces the Unix line feed line ending character.

Note: If this is an already existing project, simply run this command to update the files for the application using the newly defined line ending as specified in the .gitattributes.

git rm --cached -r .
git reset --hard

That's all.

I hope this helps

In C++ the only difference between a class and a struct is that members and base classes are private by default in classes, whereas they are public by default in structs.

So structs can have constructors, and the syntax is the same as for classes.

Okay I DON'T know much about Maven to go in finer details, but I have tried to make it work more times than I care to admit.
For me to use Maven is quite simple provided:
.You need to "hire" a special Maven guru which you don't for ant; otherwise ask your developers to spend time learning how to "build" their work instead of leaning how to "do" their work
.You need to "buy" the Book "they" sell if you want to really understant it.

And then:
.It basically solves only one real problem "dependencies" I wonder how many projects are out there who depend on so many many many other projects that they need a special tool to solve dependencies for them? And ANT can't do it?
. I personally don't upgrade to newer versions of open source frameworks blindly without seeing the need to do so. If it is working then don't fix it, right?

But then this is subjective is right?

Shortest (correct) version:

grep -q "something" file; [ $? -eq 0 ] && echo "yes" || echo "no"

can be also written as

grep -q "something" file; test $? -eq 0 && echo "yes" || echo "no"

but you dont need to explicitly test it in this case, so the same with:

grep -q "something" file && echo "yes" || echo "no"

Just to add that there is also java.text.MessageFormat with the benefit of having numeric argument indexes.

Appending the 1st example from the documentation

int planet = 7;
String event = "a disturbance in the Force";

String result = MessageFormat.format(
    "At {1,time} on {1,date}, there was {2} on planet {0,number,integer}.",
    planet, new Date(), event);

Result:

At 12:30 PM on Jul 3, 2053, there was a disturbance in the Force on planet 7.

if you are using inline coding in single page and not using oops than go with this full example, it will sure help

//connect to the db
$dbh = new PDO('mysql:host=localhost;dbname=mydb', dbuser, dbpw); 

//build the query
$query="SELECT field1, field2
FROM ubertable
WHERE field1 > 6969";

//execute the query
$data = $dbh->query($query);
//convert result resource to array
$result = $data->fetchAll(PDO::FETCH_ASSOC);

//view the entire array (for testing)
print_r($result);

//display array elements
foreach($result as $output) {
echo output[field1] . " " . output[field1] . "<br />";
}

One way, making the preprocessor do the work. It also ensures your enums and strings are in sync.

#define FOREACH_FRUIT(FRUIT) \
        FRUIT(apple)   \
        FRUIT(orange)  \
        FRUIT(grape)   \
        FRUIT(banana)  \

#define GENERATE_ENUM(ENUM) ENUM,
#define GENERATE_STRING(STRING) #STRING,

enum FRUIT_ENUM {
    FOREACH_FRUIT(GENERATE_ENUM)
};

static const char *FRUIT_STRING[] = {
    FOREACH_FRUIT(GENERATE_STRING)
};

After the preprocessor gets done, you'll have:

enum FRUIT_ENUM {
    apple, orange, grape, banana,
};

static const char *FRUIT_STRING[] = {
    "apple", "orange", "grape", "banana",
};

Then you could do something like:

printf("enum apple as a string: %s\n",FRUIT_STRING[apple]);

If the use case is literally just printing the enum name, add the following macros:

#define str(x) #x
#define xstr(x) str(x)

Then do:

printf("enum apple as a string: %s\n", xstr(apple));

In this case, it may seem like the two-level macro is superfluous, however, due to how stringification works in C, it is necessary in some cases. For example, let's say we want to use a #define with an enum:

#define foo apple

int main() {
    printf("%s\n", str(foo));
    printf("%s\n", xstr(foo));
}

The output would be:

foo
apple

This is because str will stringify the input foo rather than expand it to be apple. By using xstr the macro expansion is done first, then that result is stringified.

See Stringification for more information.

• It is a part of Java Foundation Classes
• Swing is built on AWT
• Swing components are lightweight
• Swing supports pluggable look and feel
• Platform independent
• Uses MVC : Model-View-Controller architecture
• package : javax.swing
• Unlike Swing’s other components, which are lightweight, the top-level containers are heavyweight.

You can't do it in PHP. PHP supports "include", but you can't even do that inside of a class definition. Not a lot of great options here.

This doesn't answer your question directly, but you may be interested in "Namespaces", a terribly ugly\syntax\hacked\on\top\of PHP OOP: http://www.php.net/manual/en/language.namespaces.rationale.php

#in lib/core_extensions.rb
class Hash
  #pass single or array of keys, which will be removed, returning the remaining hash
  def remove!(*keys)
    keys.each{|key| self.delete(key) }
    self
  end

  #non-destructive version
  def remove(*keys)
    self.dup.remove!(*keys)
  end
end

#in config/initializers/app_environment.rb (or anywhere in config/initializers)
require 'core_extensions'

I've set this up so that .remove returns a copy of the hash with the keys removed, while remove! modifies the hash itself. This is in keeping with ruby conventions. eg, from the console

>> hash = {:a => 1, :b => 2}
=> {:b=>2, :a=>1}
>> hash.remove(:a)
=> {:b=>2}
>> hash
=> {:b=>2, :a=>1}
>> hash.remove!(:a)
=> {:b=>2}
>> hash
=> {:b=>2}
>> hash.remove!(:a, :b)
=> {}
