For PyCharm 2017

We can follow below: File >> Settings >> Editor >> Code Style.

Then provide values for Hard Wrap & Visual Guides for wrapping while typing, tick the checkbox.

NB: look at other tabs as well, viz. Python, HTML, JSON etc.

This is a bit more readable:

Object[] allValues = all.getDeclaringClass().getEnumConstants();

If you forward-declare Flight and Landing in Event.h, then you should be fixed.

Remember to #include "Flight.h" and #include "Landing.h" in your implementation file for Event.

The general rule of thumb is: if you derive from it, or compose from it, or use it by value, the compiler must know its full definition at the time of declaration. If you compose from a pointer-to-it, the compiler will know how big a pointer is. Similarly, if you pass a reference to it, the compiler will know how big the reference is, too.

Building on Rene's answer, you could also write a function that returned either TRUE if the substring was present, or FALSE if it wasn't:

Public Function Contains(strBaseString As String, strSearchTerm As String) As Boolean
'Purpose: Returns TRUE if one string exists within another
On Error GoTo ErrorMessage
    Contains = InStr(strBaseString, strSearchTerm)
Exit Function
ErrorMessage:
MsgBox "The database has generated an error. Please contact the database administrator, quoting the following error message: '" & Err.Description & "'", vbCritical, "Database Error"
End
End Function

It should also be noted that if you have buttons grouped together on your user form that it can link it to a different button in the group despite the one you intended being clicked.

To enable the same edmx to access multiple databases and database providers and vise versa I use the following technique:

1) Define a ConnectionManager:

public static class ConnectionManager
{
    public static string GetConnectionString(string modelName)
    {
        var resourceAssembly = Assembly.GetCallingAssembly();

        var resources = resourceAssembly.GetManifestResourceNames();

        if (!resources.Contains(modelName + ".csdl")
            || !resources.Contains(modelName + ".ssdl")
            || !resources.Contains(modelName + ".msl"))
        {
            throw new ApplicationException(
                    "Could not find connection resources required by assembly: "
                    + System.Reflection.Assembly.GetCallingAssembly().FullName);
        }

        var provider = System.Configuration.ConfigurationManager.AppSettings.Get(
                        "MyModelUnitOfWorkProvider");

        var providerConnectionString = System.Configuration.ConfigurationManager.AppSettings.Get(
                        "MyModelUnitOfWorkConnectionString");

        string ssdlText;

        using (var ssdlInput = resourceAssembly.GetManifestResourceStream(modelName + ".ssdl"))
        {
            using (var textReader = new StreamReader(ssdlInput))
            {
                ssdlText = textReader.ReadToEnd();
            }
        }

        var token = "Provider=\"";
        var start = ssdlText.IndexOf(token);
        var end = ssdlText.IndexOf('"', start + token.Length);
        var oldProvider = ssdlText.Substring(start, end + 1 - start);

        ssdlText = ssdlText.Replace(oldProvider, "Provider=\"" + provider + "\"");

        var tempDir = Environment.GetEnvironmentVariable("TEMP") + '\\' + resourceAssembly.GetName().Name;
        Directory.CreateDirectory(tempDir);

        var ssdlOutputPath = tempDir + '\\' + Guid.NewGuid() + ".ssdl";

        using (var outputFile = new FileStream(ssdlOutputPath, FileMode.Create))
        {
            using (var outputStream = new StreamWriter(outputFile))
            {
                outputStream.Write(ssdlText);
            }
        }

        var eBuilder = new EntityConnectionStringBuilder
        {
            Provider = provider,

            Metadata = "res://*/" + modelName + ".csdl"
                        + "|" + ssdlOutputPath
                        + "|res://*/" + modelName + ".msl",

            ProviderConnectionString = providerConnectionString
        };

        return eBuilder.ToString();
    }
}

2) Modify the T4 that creates your ObjectContext so that it will use the ConnectionManager:

public partial class MyModelUnitOfWork : ObjectContext
{
    public const string ContainerName = "MyModelUnitOfWork";
    public static readonly string ConnectionString
        = ConnectionManager.GetConnectionString("MyModel");

3) Add the following lines to App.Config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="MyModelUnitOfWork" connectionString=... />
  </connectionStrings>
  <appSettings>
    <add key="MyModelUnitOfWorkConnectionString" value="data source=MyPc\SqlExpress;initial catalog=MyDB;integrated security=True;multipleactiveresultsets=True" />
    <add key="MyModelUnitOfWorkProvider" value="System.Data.SqlClient" />
  </appSettings>
</configuration>

The ConnectionManager will replace the ConnectionString and Provider to what ever is in the App.Config.

You can use the same ConnectionManager for all ObjectContexts (so they all read the same settings from App.Config), or edit the T4 so it creates one ConnectionManager for each (in its own namespace), so that each reads separate settings.

You can now use CSS Grid to fix this.

<div class="outer">
  <div class="top"> </div>
  <div class="below"> </div>
</div>

And the css for this:

.outer {
  display: grid;
  grid-template: 1fr / 1fr;
  place-items: center;
}
.outer > * {
  grid-column: 1 / 1;
  grid-row: 1 / 1;
}
.outer .below {
  z-index: 2;
}
.outer .top {
  z-index: 1;
}

Use a simple background image for the textarea suffice.

Or

<div onselectstart="return false">your text</div>

for github pages I Use

ng build --prod --base-href "https://<username>.github.io/<RepoName>/" --output-path=docs

This is what that copies output into the docs folder : --output-path=docs

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

Try (maybe as root)

lsof -i -P

and grep the output for the port you are looking for.

For example to check for port 80 do

lsof -i -P | grep :80

You can just type in command line (console) on Linux, in the repository directory:

$ git status

and you will see some text, among which something similar to:

...
On branch master
...

which means you are currently on master branch. If you are editing any file at that moment and it is located in the same local repository (local directory containing the files that are under Git version control management), you are editing file in this branch.

What works for me was org.mockito.ArgumentMatchers.isA

for example:

isA(long[].class)

that works fine.

the implementation difference of each other is:

public static <T> T any(Class<T> type) {
    reportMatcher(new VarArgAware(type, "<any " + type.getCanonicalName() + ">"));
    return Primitives.defaultValue(type);
}

public static <T> T isA(Class<T> type) {
    reportMatcher(new InstanceOf(type));
    return Primitives.defaultValue(type);
}

Following from Daniel Vassallo's answer, here is a version that deals with the closure issue in a simpler way.

Since since all markers will have an individual InfoWindow and since JavaScript doesn't care if you add extra properties to an object, all you need to do is add an InfoWindow to the Marker's properties and then call the .open() on the InfoWindow from itself!

Edit: With enough data, the pageload could take a lot of time, so rather than construction the InfoWindow with the marker, the construction should happen only when needed. Note that any data used to construct the InfoWindow must be appended to the Marker as a property (data). Also note that after the first click event, infoWindow will persist as a property of it's marker so the browser doesn't need to constantly reconstruct.

var locations = [
  ['Bondi Beach', -33.890542, 151.274856, 4],
  ['Coogee Beach', -33.923036, 151.259052, 5],
  ['Cronulla Beach', -34.028249, 151.157507, 3],
  ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
  ['Maroubra Beach', -33.950198, 151.259302, 1]
];

var map = new google.maps.Map(document.getElementById('map'), {
  center: new google.maps.LatLng(-33.92, 151.25)
});

for (i = 0; i < locations.length; i++) {  
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map,
    data: {
      name: locations[i][0]
    }
  });
  marker.addListener('click', function() {
    if(!this.infoWindow) {
      this.infoWindow = new google.maps.InfoWindow({
        content: this.data.name;
      });
    }
    this.infoWindow.open(map,this);
  })
}

It's an implicit conversion to bool. I.e. wherever implicit conversions are allowed, your class can be converted to bool by calling that method.

I found many of the Q&A on this topic, not nothing was helping me - that's because my issue was more basic ( what can I say I am not a networking guru :) ). My ip address in /etc/hosts was incorrect. What I had tried included the following for CATALINA_OPTS:

CATALINA_OPTS="$CATALINA_OPTS -Djava.awt.headless=true -Xmx128M -server 
-Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=7091 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=A.B.C.D"  #howeverI put the wrong ip here!

export CATALINA_OPTS

My problem was that I had changed my ip address many months ago, but never updated my /etc/hosts file. it seems that by default the jconsole uses the hostname -i ip address in some fashion even though I was viewing local processes. The best solution was to simply change the /etc/hosts file.

The other solution which can work is to get your correct ip address from /sbin/ifconfig and use that ip address when specifying the ip address in, for example, a catalina.sh script:

-Djava.rmi.server.hostname=A.B.C.D

The best and easy way to pass single or multiple variables to view from controller is to use compact() method.

For passing single variable to view,

return view("user/regprofile",compact('students'));

For passing multiple variable to view,

return view("user/regprofile",compact('students','teachers','others'));

And in view, you can easily loop through the variable,

@foreach($students as $student)
   {{$student}}
@endforeach

I was looking for this:

<properties>
    <maven.compiler.target>1.8</maven.compiler.target>
    <maven.compiler.source>1.8</maven.compiler.source>
</properties>

In my situation I had moved the htdocs to a new location updated in httpd.conf, which worked fine. I then received the same error after updating the httpd-vhost.conf file.

I found that the error was caused by a typo in the vhost configuration file. Previously I changed all "DocumentRoot" ’s to the new htdocs location, but had forgot to update the new location for "ErrorLog". After correcting the missing path, Apache was running smooth again.

Owing to changes in React V16 where componentWillReceiveProps() has been deprecated, this is the methodology that I use for updating a component. Notice that the below example is in Typescript and uses the static getDerivedStateFromProps method to get the initial state and updated state whenever the Props are updated.

    class SomeClass extends React.Component<Props, State> {
  static getDerivedStateFromProps(nextProps: Readonly<Props>): Partial<State> | null {
    return {
      time: nextProps.time
    };
  }

  timerInterval: any;

  componentDidMount() {
    this.timerInterval = setInterval(this.tick.bind(this), 1000);
  }

  tick() {
    this.setState({ time: this.props.time });
  }

  componentWillUnmount() {
    clearInterval(this.timerInterval);
  }

  render() {
    return <div>{this.state.time}</div>;
  }
}

I did downgrade the node version from 12 to 10

EDIT

This error occurred with me because I was using node version 12. When I downgrade to version 10.16.5 this error stops. This error happened in my local env, but in prod and staging, it not happens. In prod and staging node version is 10.x so I just do this and I didn't need to update any package in my package.json

You can't set X-Frame-Options on the iframe. That is a response header set by the domain from which you are requesting the resource (google.com.ua in your example). They have set the header to SAMEORIGIN in this case, which means that they have disallowed loading of the resource in an iframe outside of their domain. For more information see The X-Frame-Options response header on MDN.

A quick inspection of the headers (shown here in Chrome developer tools) reveals the X-Frame-Options value returned from the host.

It's actually possible to effectively define a variable that can be used in both the SELECT, WHERE and other clauses.

A cross join doesn't necessarily allow for appropriate binding to the referenced table columns, however OUTER APPLY does - and treats nulls more transparently.

SELECT
    vars.BalanceDue
FROM
    Entity e
OUTER APPLY (
    SELECT
        -- variables   
        BalanceDue = e.EntityTypeId,
        Variable2 = ...some..long..complex..expression..etc...
    ) vars
WHERE
    vars.BalanceDue > 0

Kudos to Syed Mehroz Alam.

var test = document.getElementById( 'test' );

// To get the text only, you can use "textContent"
console.log( test.textContent ); // "1 2 3 4"

textContent is the standard way. innerText is the property to use for legacy IE. If you want something as cross browser as possible, recursively use nodeValue.

After some changing to above Henry's answer, I got a tick with in a circle, I came here looking for that, so adding my code here.

.snackbar_circle {
  background-color: #f0f0f0;
  border-radius: 13px;
  padding: 0 5px;
}

.checkmark {
  font-family: arial;
  font-weight: bold;
  -ms-transform: scaleX(-1) rotate(-35deg);
  -webkit-transform: scaleX(-1) rotate(-35deg);
  transform: scaleX(-1) rotate(-35deg);
  color: #63BA3D;
  display: inline-block;
}

<span class="snackbar_circle">
   <span class="checkmark">L</span>
</span>

If you are using C++11, you should probably use stoi because it can distinguish between an error and parsing "0".

try {
    int number = std::stoi("1234abc");
} catch (std::exception const &e) {
    // This could not be parsed into a number so an exception is thrown.
    // atoi() would return 0, which is less helpful if it could be a valid value.
}

It should be noted that "1234abc" is implicitly converted from a char[] to a std:string before being passed to stoi().

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

Hmmm you can find lot of examples for configuring spring framework. Anyways here is a sample

Assuming maven project: Properties file should be in src/main/resources/database folder

jdbc.properties file

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true

ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.

Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.

public interface ServiceMarker {

}

Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker

public interface RepositoryMarker {

}

a.b.c.entities.Student

//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {

    private LocalDateTime fromDate;
    private LocalDateTime toDate;

    //getters setters

}

a.b.c.converters

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {

        if (dateTime == null) {
            return null;
        }
        return Timestamp.valueOf(dateTime);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {

        if (timestamp == null) {
            return null;
        }    
        return timestamp.toLocalDateTime();
    }
}

You cannot calculate the differences separately ... what difference would that yield for 7:59 and 8:00 o'clock? Try

import time
time.time()

which gives you the seconds since the start of the epoch.

You can then get the intermediate time with something like

timestamp1 = time.time()
# Your code here
timestamp2 = time.time()
print "This took %.2f seconds" % (timestamp2 - timestamp1)

The other solutions I've seen here so far are based on some system definitions, but it's in fact possible to have sudo use the current PATH (with the env command) and/or the rest of the environment (with the -E option) just by invoking it right:

sudo -E env "PATH=$PATH" <command> [arguments]

In fact, one can make an alias out of it:

alias mysudo='sudo -E env "PATH=$PATH"'

(It's also possible to name the alias itself sudo, replacing the original sudo.)

If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:

sudo nano .bashrc

chmod 777 .bashrc 

it is worthless

The Datetime format field has the following format 'YYYY-MM-DD HH:MM:SS.S'

That statement is false. That's just how Enterprise Manager or SQL Server chooses to show the date. Internally it's a 8-byte binary value, which is why some of the functions posted by Andrew will work so well.

Kibbee makes a valid point as well, and in a perfect world I would agree with him. However, sometimes you want to bind query results directly to display control or widgets and there's really not a chance to do any formatting. And sometimes the presentation layer lives on a web server that's even busier than the database. With those in mind, it's not necessarily a bad thing to know how to do this in SQL.

Faced with the same issue, supporting older devices via the deprecated camera API and needing the new Camera2 API for both current devices and moving into the future; I ran into the same issues -- and have not found a 3rd party library that bridges the 2 APIs, likely because they are very different, I turned to basic OOP principals.

The 2 APIs are markedly different making interchanging them problematic for client objects expecting the interfaces presented in the old API. The new API has different objects with different methods, built using a different architecture. Got love for Google, but ragnabbit! that's frustrating.

So I created an interface focussing on only the camera functionality my app needs, and created a simple wrapper for both APIs that implements that interface. That way my camera activity doesn't have to care about which platform its running on...

I also set up a Singleton to manage the API(s); instancing the older API's wrapper with my interface for older Android OS devices, and the new API's wrapper class for newer devices using the new API. The singleton has typical code to get the API level and then instances the correct object.

The same interface is used by both wrapper classes, so it doesn't matter if the App runs on Jellybean or Marshmallow--as long as the interface provides my app with what it needs from either Camera API, using the same method signatures; the camera runs in the App the same way for both newer and older versions of Android.

The Singleton can also do some related things not tied to the APIs--like detecting that there is indeed a camera on the device, and saving to the media library.

I hope the idea helps you out.

The use of "closed" vs. "open" reflects whether or not we are locked in to using a certain position or data structure (this is an extremely vague description, but hopefully the rest helps).

For instance, the "open" in "open addressing" tells us the index (aka. address) at which an object will be stored in the hash table is not completely determined by its hash code. Instead, the index may vary depending on what's already in the hash table.

The "closed" in "closed hashing" refers to the fact that we never leave the hash table; every object is stored directly at an index in the hash table's internal array. Note that this is only possible by using some sort of open addressing strategy. This explains why "closed hashing" and "open addressing" are synonyms.

Contrast this with open hashing - in this strategy, none of the objects are actually stored in the hash table's array; instead once an object is hashed, it is stored in a list which is separate from the hash table's internal array. "open" refers to the freedom we get by leaving the hash table, and using a separate list. By the way, "separate list" hints at why open hashing is also known as "separate chaining".

In short, "closed" always refers to some sort of strict guarantee, like when we guarantee that objects are always stored directly within the hash table (closed hashing). Then, the opposite of "closed" is "open", so if you don't have such guarantees, the strategy is considered "open".

The way I'm doing it now is basically like this:

The HTML:

<textarea id="myText">
    Lorem ipsum...
</textarea>
<button onclick="sendMail(); return false">Send</button>

The Javascript:

function sendMail() {
    var link = "mailto:[email protected]"
             + "[email protected]"
             + "&subject=" + encodeURIComponent("This is my subject")
             + "&body=" + encodeURIComponent(document.getElementById('myText').value)
    ;
    
    window.location.href = link;
}

This, surprisingly, works rather well. The only problem is that if the body is particularly long (somewhere over 2000 characters), then it just opens a new email but there's no information in it. I suspect that it'd be to do with the maximum length of the URL being exceeded.

There is an open source offline package deployer for Windows which I wrote:

You can try this out to see if it meets your needs.

bundler update --source gem-name will update the revision hash in Gemfile.lock which you can compare with the last commit hash of that git branch (master by default).

GIT remote: [email protected]:organization/repo-name.git revision: c810f4a29547b60ca8106b7a6b9a9532c392c954

can be found at github.com/organization/repo-name/commits/c810f4a2 (I used shorthand 8 character commit hash for the url)

This method will help you to logout from facebook programmatically in android

/**
 * Logout From Facebook 
 */
public static void callFacebookLogout(Context context) {
    Session session = Session.getActiveSession();
    if (session != null) {

        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
            //clear your preferences if saved
        }
    } else {

        session = new Session(context);
        Session.setActiveSession(session);

        session.closeAndClearTokenInformation();
            //clear your preferences if saved

    }

}

If we want output like 'string0123456789' then we can use map function and join method of string.

>>> 'string'+"".join(map(str,xrange(10)))
'string0123456789'

If we want List of string values then use list comprehension method.

>>> ['string'+i for i in map(str,xrange(10))]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9']

Note:

Use xrange() for Python 2.x

USe range() for Python 3.x

Thanks to Ging3r i got solution:

follow these steps:

1. don't use in dependency tag. Use following in dependencies tag in pom.xml file::

   <dependency>
   <groupId>com.netsuite.suitetalk.proxy.v2019_1</groupId>
   <artifactId>suitetalk-axis-proxy-v2019_1</artifactId>
   <version>1.0.0</version>
   </dependency>
   <dependency>
       <groupId>com.netsuite.suitetalk.client.v2019_1</groupId>
       <artifactId>suitetalk-client-v2019_1</artifactId>

I am including 3 jars from lib folder:

Finally, use mvn clean and then mvn install or 'mvn clean install' and just run jar file from target folder or the path where install(see mvn install log):

java -jar abc.jar

note: Remember one thing if you are working at jenkins then first use mvn clean and then mvn clean install command work for you because with previous code mvn clean install command store cache for dependency.

Although the answers above seems correct, just a simple explanation to give you an idea of how it works.

Suppose that your column is set to be DECIMAL(13,4). This means that the column will have a total size of 13 digits where 4 of these will be used for precision representation.

So, in summary, for that column you would have a max value of: 999999999.9999

Please use

plt.show(block=False)
plt.close('all')

The no-js class is used to style a webpage, dependent on whether the user has JS disabled or enabled in the browser.

As per the Modernizr docs:

no-js

By default, Modernizr will rewrite <html class="no-js"> to <html class="js">. This lets hide certain elements that should only be exposed in environments that execute JavaScript. If you want to disable this change, you can set enableJSClass to false in your config.

IDK if this is relevant here, but if you have Git Installed, you can find the openssl in the "C:\Program Files\Git\usr\bin" and that location you can use in the Terminal for your Keystore Command.

oh and yeah the command:

keytool -exportcert -alias keystore -keystore "C:\Users\YOURPATH/filename.jks" | "C:\Program Files\Git\usr\bin\openssl" sha1 -binary | "C:\Program Files\Git\usr\bin\openssl" base64

I mostly prefer Criteria Queries for dynamic queries. For example it is much easier to add some ordering dynamically or leave some parts (e.g. restrictions) out depending on some parameter.

On the other hand I'm using HQL for static and complex queries, because it's much easier to understand/read HQL. Also, HQL is a bit more powerful, I think, e.g. for different join types.

DESCRIBE <table>; 

This is acutally a shortcut for:

SHOW COLUMNS FROM <table>;

In any case, there are three possible values for the "Key" attribute:

1. PRI
2. UNI
3. MUL

The meaning of PRI and UNI are quite clear:

• PRI => primary key
• UNI => unique key

The third possibility, MUL, (which you asked about) is basically an index that is neither a primary key nor a unique key. The name comes from "multiple" because multiple occurrences of the same value are allowed. Straight from the MySQL documentation:

If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

There is also a final caveat:

If more than one of the Key values applies to a given column of a table, Key displays the one with the highest priority, in the order PRI, UNI, MUL.

As a general note, the MySQL documentation is quite good. When in doubt, check it out!

If I understand your issue this should work

&emsp—the em space; this should be a very wide space, typically as much as four real spaces. &ensp—the en space; this should be a somewhat wide space, roughly two regular spaces. &thinsp—this will be a narrow space, even more narrow than a regular space.

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

Thanks to this link: Less Aggressive Compilation with CSS3 calc

You can refine your search to only find those divs with a given class using BS3:

mydivs = soup.find_all("div", {"class": "stylelistrow"})

One other thing that can cause "ambiguous redirect" is \t \n \r in the variable name you are writing too

Maybe not \n\r? But err on the side of caution

Try this

echo "a" > ${output_name//[$'\t\n\r']}

I got hit with this one while parsing HTML, Tabs \t at the beginning of the line.

System.setProperty("gate.home", "/some/directory");

I configured the app.config with the tool for EntLib configuration and set up my LoggingConfiguration block. Then I copied this into the DotNetConfig.xsd. Of course, it does not cover all attributes, only the ones I added but it does not display those annoying info messages anymore.

In .NetCore, you can add the following code snippet at services configure method , I added a check to make sure only that we by pass the SSL certificate in development environment only

services.AddHttpClient("HttpClientName", client => {
// code to configure headers etc..
}).ConfigurePrimaryHttpMessageHandler(() => {
                  var handler = new HttpClientHandler();
                  if (hostingEnvironment.IsDevelopment())
                  {
                      handler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => { return true; };
                  }
                  return handler;
              });

// Path relative to where the php file is or absolute server path
chdir($FilePath); // Comment this out if you are on the same folder
chown($FileName,465); //Insert an Invalid UserId to set to Nobody Owner; for instance 465
$do = unlink($FileName);

if($do=="1"){ 
    echo "The file was deleted successfully."; 
} else { echo "There was an error trying to delete the file."; } 

Try this. Hope it helps.

After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:

https://browserstrangeness.github.io/css_hacks.html

It's a crazy, weird media query, but those are easier to use in Sass:

@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
   .selector { rule: value };
}

This targets IE versions expect for IE8.

Or you can use:

@media screen\0 {
  .selector { rule: value };
}

Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).

Right now I'm testing with print support, and this seems to be working okay:

@media all\0 {
  .selector { rule: value };
}

. matches any character so needs escaping i.e. \., or \\. within a Java string (because \ itself has special meaning within Java strings.)

You can then use \.\. or \.{2} to match exactly 2 dots.

This will not expand the last column of the xaml grid to take the remaining space if AutoGeneratedColumns="True".

yo can extend your JS with a select method like this

Array.prototype.select = function(closure){
    for(var n = 0; n < this.length; n++) {
        if(closure(this[n])){
            return this[n];
        }
    }

    return null;
};

now you can use this:

var x = [1,2,3,4];

var a = x.select(function(v) {
    return v == 2;
});

console.log(a);

or for objects in a array

var x = [{id: 1, a: true},
    {id: 2, a: true},
    {id: 3, a: true},
    {id: 4, a: true}];

var a = x.select(function(obj) {
    return obj.id = 2;
});

console.log(a);

Sounds like you're calling sp_executesql with a VARCHAR statement, when it needs to be NVARCHAR.

e.g. This will give the error because @SQL needs to be NVARCHAR

DECLARE @SQL VARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

So:

DECLARE @SQL NVARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

Instead of getViewById(), use

MenuItem item = getToolbar().getMenu().findItem(Menu.FIRST);

replacing the Menu.FIRST with your menu item id.

In Swift 3.0 Apple removed 'NS' prefix and made everything simple. Below is the way to get hour, minute and second from 'Date' class (NSDate alternate)

let date = Date()
let calendar = Calendar.current

let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("hours = \(hour):\(minutes):\(seconds)")

Like these you can get era, year, month, date etc. by passing corresponding.

I'm the author of iso8601 utils. It can be found on GitHub or on PyPI. Here's how you can parse your example:

>>> from iso8601utils import parsers
>>> parsers.datetime('2008-09-03T20:56:35.450686Z')
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686)

I guess you will get ORA-01741: illegal zero-length identifier if you use the following

SELECT "" AS Contact  FROM Customers;

And if you use the following 2 statements, you will be getting the same null value populated in the column.

SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;

There are 2 ways of doing this

foreach($questions as $key => $question){
    $questions[$key]['answers'] = $answers_model->get_answers_by_question_id($question['question_id']);
}

This way you save the key, so you can update it again in the main $questions variable

or

foreach($questions as &$question){

Adding the & will keep the $questions updated. But I would say the first one is recommended even though this is shorter (see comment by Paystey)

Per the PHP foreach documentation:

In order to be able to directly modify array elements within the loop precede $value with &. In that case the value will be assigned by reference.

This will do what you want, uses an input file and is super fast

#!/bin/bash
IFS=$'\n'
file=/path/to/input.txt
lines=$(cat ${file})
for line in ${lines}; do
   curl "${line}"
done
IFS=""
exit ${?}

one entry per line on your input file, it will follow the order of your input file

save it as whatever.sh and make it executable

Using Node.js v8 or later has a new feature that converts normal function into an async function.

util.promisify

It's an awesome feature. Here's the example of parsing 10000 numbers from the txt file into an array, counting inversions using merge sort on the numbers.

// read from txt file
const util = require('util');
const fs = require('fs')
fs.readFileAsync = util.promisify(fs.readFile);
let result = []

const parseTxt = async (csvFile) => {
  let fields, obj
  const data = await fs.readFileAsync(csvFile)
  const str = data.toString()
  const lines = str.split('\r\n')
  // const lines = str
  console.log("lines", lines)
  // console.log("str", str)

  lines.map(line => {
    if(!line) {return null}
    result.push(Number(line))
  })
  console.log("result",result)
  return result
}
parseTxt('./count-inversion.txt').then(() => {
  console.log(mergeSort({arr: result, count: 0}))
})

Found another one:

SELECT 
     KU.table_name as TABLENAME
    ,column_name as PRIMARYKEYCOLUMN
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC 

INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KU
    ON TC.CONSTRAINT_TYPE = 'PRIMARY KEY' 
    AND TC.CONSTRAINT_NAME = KU.CONSTRAINT_NAME 
    AND KU.table_name='YourTableName'

ORDER BY 
     KU.TABLE_NAME
    ,KU.ORDINAL_POSITION
; 

I have tested this on SQL Server 2003/2005

You can use:

window.location.href = '/Branch/Details/' + id;

But your Ajax code is incomplete without success or error functions.

I like to simplify the code without using conditional operators in such cases:

TEMP=/mnt/silo/bin
[[ ${PATH} =~ ${TEMP} ]] || PATH=$PATH:$TEMP

Use rsync so that you can continue if the connection gets broken. And if something changes you can copy them much faster too!

Rsync works with SSH so your copy operation is secure.

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT function on the nvarchar field.

Example: Left(Field,4)

Basically, the query will look like:

Select convert(float,left(Field,4)) from TABLE

Just ridiculous that SQL would complicate it to this extent, while with C# it's a breeze!
Hope it helps someone out there.

I think my answer will be more technical, but not different as the others present the same thing using different techniques.
So, first things first, the solution to this problem is the use of a design pattern known as "observer", it let's you decouple your data from your presentation, making the change in one thing be broadcasted to their listeners, but in this case it's made two-way.

For the DOM to JS way

To bind the data from the DOM to the js object you may add markup in the form of data attributes (or classes if you need compatibility), like this:

<input type="text" data-object="a" data-property="b" id="b" class="bind" value=""/>
<input type="text" data-object="a" data-property="c" id="c" class="bind" value=""/>
<input type="text" data-object="d" data-property="e" id="e" class="bind" value=""/>

This way it can be accessed via js using querySelectorAll (or the old friend getElementsByClassName for compatibility).

Now you can bind the event listening to the changes in to ways: one listener per object or one big listener to the container/document. Binding to the document/container will trigger the event for every change made in it or it's child, it willhave a smaller memory footprint but will spawn event calls.
The code will look something like this:

//Bind to each element
var elements = document.querySelectorAll('input[data-property]');

function toJS(){
    //Assuming `a` is in scope of the document
    var obj = document[this.data.object];
    obj[this.data.property] = this.value;
}

elements.forEach(function(el){
    el.addEventListener('change', toJS, false);
}

//Bind to document
function toJS2(){
    if (this.data && this.data.object) {
        //Again, assuming `a` is in document's scope
        var obj = document[this.data.object];
        obj[this.data.property] = this.value;
    }
}

document.addEventListener('change', toJS2, false);

For the JS do DOM way

You will need two things: one meta-object that will hold the references of witch DOM element is binded to each js object/attribute and a way to listen to changes in objects. It is basically the same way: you have to have a way to listen to changes in the object and then bind it to the DOM node, as your object "can't have" metadata you will need another object that holds metadata in a way that the property name maps to the metadata object's properties. The code will be something like this:

var a = {
        b: 'foo',
        c: 'bar'
    },
    d = {
        e: 'baz'
    },
    metadata = {
        b: 'b',
        c: 'c',
        e: 'e'
    };
function toDOM(changes){
    //changes is an array of objects changed and what happened
    //for now i'd recommend a polyfill as this syntax is still a proposal
    changes.forEach(function(change){
        var element = document.getElementById(metadata[change.name]);
        element.value = change.object[change.name];
    });
}
//Side note: you can also use currying to fix the second argument of the function (the toDOM method)
Object.observe(a, toDOM);
Object.observe(d, toDOM);

I hope that i was of help.

I was setting MIME type from .NET code as below -

My application generates excel using OpenXML SDK. This MIME type worked -

vnd.openxmlformats-officedocument.spreadsheetml.sheet

In an attempt to find a way to make the target cell for the intersect method a name table array, I stumbled across a simple way to run something when ANY cell or set of cells on a particular sheet changes. This code is placed in the worksheet module as well:

If Target.Cells.Count > 0 Then
'mycode here
end if

I have tested this connecting to both Windows Server 2003 and Windows Server 2008 R2 domain controllers from a Windows Server 2003 Web Server (IIS6) and from a windows server 2012 enterprise running IIS 8.

One of the best resources I found was using let's encrypt, you do not need ELB nor cloudfront for your EC2 instance to have HTTPS, just follow the following simple instructions: let's encrypt Login to your server and follow the steps in the link.

It is also important as mentioned by others that you have port 443 opened by editing your security groups

You can view your certificate or any other website's by changing the site name in this link

Please do not forget that it is only valid for 90 days

    content: " ";
    height: 100%;
  }
}

.modal-dialog {

And adjust a little bit .fade class to make sure it appears out of the top border of window, instead of center

From the PHP manual:

This function displays structured information about one or more expressions that includes its type and value.

So, here is the real return version of PHP's var_dump(), which actually accepts a variable-length argument list:

function var_dump_str()
{
    $argc = func_num_args();
    $argv = func_get_args();

    if ($argc > 0) {
        ob_start();
        call_user_func_array('var_dump', $argv);
        $result = ob_get_contents();
        ob_end_clean();
        return $result;
    }

    return '';
}

How about something like:

includes = $(wildcard include/*.h)

%.o: %.c ${includes}
    gcc -Wall -Iinclude ...

You could also use the wildcards directly, but I tend to find I need them in more than one place.

Note that this only works well on small projects, since it assumes that every object file depends on every header file.

replace:

input, select, textarea{
    color: #000;
}

with:

input, select, textarea{
    color: #f00;
}

or color: #ff0000;

it worked for me..

countries.results= $.grep(countries.results, function (e) { 
      if(e.id!= currentID) {
       return true; 
      }
     });

If you want use custom roles, you can do this:

CustomRoles class:

public static class CustomRoles
{
    public const string Administrator = "Administrador";
    public const string User = "Usuario";
}

Usage

[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]

If you have few roles, maybe you can combine them (for clarity) like this:

public static class CustomRoles
{
     public const string Administrator = "Administrador";
     public const string User = "Usuario";
     public const string AdministratorOrUser = Administrator + "," + User;  
}

Usage

[Authorize(Roles = CustomRoles.AdministratorOrUser)]

Try changing the order of dependencies in File > Project Structure > (select your project) > Dependencies.

Invalidate Caches didn't work for me, but moving my build from the bottom of the list to the top did.

You can try this

int array[20,30] = {{0}};

Try to use pointers...

  char str[] = "String1 subString1 Strinstrnd subStr ing1subString";
  char sub[] = "subString";

  char *p1, *p2, *p3;
  int i=0,j=0,flag=0;

  p1 = str;
  p2 = sub;

  for(i = 0; i<strlen(str); i++)
  {
    if(*p1 == *p2)
      {
          p3 = p1;

Teradata table or view stores NULL as "?" and SQL considers it as a character or string. This is the main reason for the error "The value violated the integrity constraints for the column." when data is ported from Teradata source to SQL destination. Solution 1: Allow the destination table to hold NULL Solution 2: Convert the '?' character to be stored as some value in the destination table.

Zero => Everything Okay

Positive => Something I expected could potentially go wrong went wrong (bad command-line, can't find file, could not connect to server)

Negative => Something I didn't expect at all went wrong (system error - unanticipated exception - externally forced termination e.g. kill -9)

(values greater than 128 are actually negative, if you regard them as 8-bit signed binary, or twos complement)

There's a load of good standard exit-codes here

I had to add port via Configuration Manager and add the port number in my sql connection [host]\[db instance name],1433

Note the , (comma) between instancename and port

SELECT ... INTO ... only works if the table specified in the INTO clause does not exist - otherwise, you have to use:

INSERT INTO dbo.TABLETWO
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

This assumes there's only two columns in dbo.TABLETWO - you need to specify the columns otherwise:

INSERT INTO dbo.TABLETWO
  (col1, col2)
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

I'd realise its a very old question, but since i wondered today for a more efficient method of handling the bootstrap modals. I did some research and found something better then the solutions which are shown above, that can be found at this link:

http://www.petefreitag.com/item/809.cfm

First load the jquery

$(document).ready(function() {
    $('a[data-confirm]').click(function(ev) {
        var href = $(this).attr('href');

        if (!$('#dataConfirmModal').length) {
            $('body').append('<div id="dataConfirmModal" class="modal" role="dialog" aria-labelledby="dataConfirmLabel" aria-hidden="true"><div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="dataConfirmLabel">Please Confirm</h3></div><div class="modal-body"></div><div class="modal-footer"><button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button><a class="btn btn-primary" id="dataConfirmOK">OK</a></div></div>');
        } 
        $('#dataConfirmModal').find('.modal-body').text($(this).attr('data-confirm'));
        $('#dataConfirmOK').attr('href', href);
        $('#dataConfirmModal').modal({show:true});
        return false;
    });
});

Then just ask any question/confirmation to href:

<a href="/any/url/delete.php?ref=ID" data-confirm="Are you sure you want to delete?">Delete</a>

This way the confirmation modal is a lot more universal and so it can easily be re-used on other parts of your website.

make in, and off itself, handles directory targets just the same as file targets. So, it's easy to write rules like this:

outDir/someTarget: Makefile outDir
    touch outDir/someTarget

outDir:
    mkdir -p outDir

The only problem with that is, that the directories timestamp depends on what is done to the files inside. For the rules above, this leads to the following result:

$ make
mkdir -p outDir
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget

This is most definitely not what you want. Whenever you touch the file, you also touch the directory. And since the file depends on the directory, the file consequently appears to be out of date, forcing it to be rebuilt.

However, you can easily break this loop by telling make to ignore the timestamp of the directory. This is done by declaring the directory as an order-only prerequsite:

# The pipe symbol tells make that the following prerequisites are order-only
#                           |
#                           v
outDir/someTarget: Makefile | outDir
    touch outDir/someTarget

outDir:
    mkdir -p outDir

This correctly yields:

$ make
mkdir -p outDir
touch outDir/someTarget
$ make
make: 'outDir/someTarget' is up to date.

TL;DR:

Write a rule to create the directory:

$(OUT_DIR):
    mkdir -p $(OUT_DIR)

And have the targets for the stuff inside depend on the directory order-only:

$(OUT_DIR)/someTarget: ... | $(OUT_DIR)

Thanks, @jowett, I have solved my same problem, doing these steps

Step 1: CTRL+Shift+Esc to open the task manager, which has adb.exe process and end (kill) that process

Step 2: Now, close the eclipse, which is currently running on my computer.

Step 3: Again, restart eclipse then solved that problem.

For those using OS X

killall adb

For those using Windows

adb kill-server

should do the trick.

I used the Google Apps Script method indexOf() and its results were wrong. So I wrote the small function Myindexof(), instead of indexOf:

function Myindexof(s,text)
{
  var lengths = s.length;
  var lengtht = text.length;
  for (var i = 0;i < lengths - lengtht + 1;i++)
  {
    if (s.substring(i,lengtht + i) == text)
      return i;
  }
  return -1;
}

var s = 'Hello!';
var text = 'llo';
if (Myindexof(s,text) > -1)
   Logger.log('yes');
else
   Logger.log('no');

Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines

You may just need addObserver in viewDidLoad. But having addObserver in viewWillAppear and removeObserver in viewWillDisappear prevents rare crashes which happens when you are changing your view.

Swift 4.2

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillDisappear), name: UIResponder.keyboardWillHideNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillAppear), name: UIResponder.keyboardWillShowNotification, object: nil)
}

@objc func keyboardWillAppear() {
    //Do something here
}

@objc func keyboardWillDisappear() {
    //Do something here
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}

Swift 3 and 4

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillDisappear), name: Notification.Name.UIKeyboardWillHide, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillAppear), name: Notification.Name.UIKeyboardWillShow, object: nil)
}

@objc func keyboardWillAppear() {
    //Do something here
}

@objc func keyboardWillDisappear() {
    //Do something here
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}

Older Swift

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)

    NSNotificationCenter.defaultCenter().addObserver(self, selector:"keyboardWillAppear:", name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector:"keyboardWillDisappear:", name: UIKeyboardWillHideNotification, object: nil)
}

func keyboardWillAppear(notification: NSNotification){
    // Do something here
}

func keyboardWillDisappear(notification: NSNotification){
    // Do something here
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    NSNotificationCenter.defaultCenter().removeObserver(self)
}

Auto-correlation comes in two versions: statistical and convolution. They both do the same, except for a little detail: The statistical version is normalized to be on the interval [-1,1]. Here is an example of how you do the statistical one:

def acf(x, length=20):
    return numpy.array([1]+[numpy.corrcoef(x[:-i], x[i:])[0,1]  \
        for i in range(1, length)])

To change multiple files (and saving a backup of each as *.bak):

perl -p -i -e "s/\|/x/g" *  

will take all files in directory and replace | with x this is called a “Perl pie” (easy as a pie)

Everyone said it, but I guess it won't hurt saying it again.

You need to set the width to some value. Here is something simpler to understand.

You can achieve it using custom log4j appender.
MaxNumberOfDays - possibility to set amount of days of rotated log files.
CompressBackups - possibility to archive old logs with zip extension.

As of PowerShell 5.1 there cmdlet New-LocalUser which could create local user account.

Example of usage:

Create a user account

New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword

or Create a user account that has a password

$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."

or Create a user account that is connected to a Microsoft account

New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account." 

I Usually go for 422 (Unprocessable entity) if something in the required parameters didn't match what the API endpoint required (like a too short password) but for a missing parameter i would go for 406 (Unacceptable).

I have the same problem. I usually resort to String#split:

"ABCDEFG".split("").each do |i|
  puts i
end

I guess you could also implement it yourself like this:

class String
  def each_char
    self.split("").each { |i| yield i }
  end
end

Edit: yet another alternative is String#each_byte, available in Ruby 1.8.6, which returns the ASCII value of each char in an ASCII string:

"ABCDEFG".each_byte do |i|
  puts i.chr # Fixnum#chr converts any number to the ASCII char it represents
end

np.log is ln, whereas np.log10 is your standard base 10 log.

Relevant documentation:

http://docs.scipy.org/doc/numpy/reference/generated/numpy.log.html

http://docs.scipy.org/doc/numpy/reference/generated/numpy.log10.html

the + sign is a short cut to add the id to your list of resource ids. Otherwise you need to have them in a xml file like this

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="my_logo" type="id"/>
</resources>

Follow up to Eonil's answer related to project level settings. With the target selected and the Build Settings tab selected, there may be no listing under Search Paths for Header Search Paths. In this case, you can change to "All" from "Basic" in the search bar and Header Search Paths will show up in the Search Paths section.

Or just use Apache CXF's wsdl2java to generate objects you can use.

It is included in the binary package you can download from their website. You can simply run a command like this:

$ ./wsdl2java -p com.mynamespace.for.the.api.objects -autoNameResolution http://www.someurl.com/DefaultWebService?wsdl

It uses the wsdl to generate objects, which you can use like this (object names are also grabbed from the wsdl, so yours will be different a little):

DefaultWebService defaultWebService = new DefaultWebService();
String res = defaultWebService.getDefaultWebServiceHttpSoap11Endpoint().login("webservice","dadsadasdasd");
System.out.println(res);

There is even a Maven plug-in which generates the sources: https://cxf.apache.org/docs/maven-cxf-codegen-plugin-wsdl-to-java.html

Note: If you generate sources using CXF and IDEA, you might want to look at this: https://stackoverflow.com/a/46812593/840315

This might be an exception occurring in the finalizer. If you are doing the Pattern of ~Class(){ Dispose(false); } check what are you disposing as an un-managed resource. Just put a try..catch there and you should be fine.

We found the issue as we had this mysterious failure with no logs We did the usual recommended pattern of using a "void Dispose(bool disposing)".

Looking at the answers on this question about the finalizer we found a possible place where the Disposal of the unmanaged resources could throw an exception.

It turns out somewhere we did not dispose the object properly thus the finalizer took over the diposal of unmanaged resources thus behold an exception occurred.

In this case was using the Kafka Rest API to clean up the client from Kafka. Seems that it did threw exception at some point then this issue occurred.

To clarify the last post:

The VBoxManage command is:

VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME> 1

There isn't so much a 'correct' way for the language. It's more personal preference or what the standard is for your team. I usually use the myFunction() when I'm doing my own code. Also, a style you didn't mention that you will often see in C++ is my_function() - no caps, underscores instead of spaces.

Really it is just dictated by the code your working in. Or, if it's your own project, your own personal preference then.

If you have a container and two sub containers, you can do like this

jQuery

    $("#previousbutton").click(function() {
    $("#form_sub_container1").show();
    $("#form_sub_container2").hide(); })

    $("#nextbutton").click(function() {
    $("#form_container").find(":hidden").show().next();
    $("#form_sub_container1").hide();
})

HTML

     <div id="form_container">
            <div id="form_sub_container1" style="display: block;">
            </div>

            <div id="form_sub_container2" style="display: none;">
            </div>
     </div>

i've successfully removed dependencies of a package using this bash line:

for dep in $(pip show somepackage | grep Requires | sed 's/Requires: //g; s/,//g') ; do pip uninstall -y $dep ; done

this worked on pip 1.5.4

Like others mentioned you cannot delete current branch in which you are working.

In my case, I have selected "Test_Branch" in Visual Studio and was trying to delete "Test_Branch" from Sourcetree (Git GUI). And was getting below error message.

Cannot delete branch 'Test_Branch' checked out at '[directory location]'.

Switched to different branch in Visual Studio and was able to delete "Test_Branch" from Sourcetree.

I hope this helps someone who is using Visual Studio & Sourcetree.

Another potential "solution" is to use the window object. It avoids the reference error problem when in a browser.

if (window.x) {
    alert('x exists and is truthy');
} else {
    alert('x does not exist, or exists and is falsy');
}

It is worth mentioning Gaphor. A Python modelling/UML tool.

I can't comment but don't want to start a new thread. But this isn't working. A simple round trip:

byte[] b = new byte[]{ 0, 0, 0, -127 };  // 0x00000081
String s = new String(b,StandardCharsets.UTF_8); // UTF8 = 0x0000, 0x0000,  0x0000, 0xfffd
b = s.getBytes(StandardCharsets.UTF_8); // [0, 0, 0, -17, -65, -67] 0x000000efbfbd != 0x00000081

I'd need b[] the same array before and after encoding which it isn't (this referrers to the first answer).

Note: This is case sensitive

function palindrome(word)
{
    for(var i=0;i<word.length/2;i++)
        if(word.charAt(i)!=word.charAt(word.length-(i+1)))
            return word+" is Not a Palindrome";
    return word+" is Palindrome";
}

Here is the fiddle: http://jsfiddle.net/eJx4v/

Commenting here as this seems to be the most popular answer on the subject for searching for files whilst excluding certain directories in powershell.

To avoid issues with post filtering of results (i.e. avoiding permission issues etc), I only needed to filter out top level directories and that is all this example is based on, so whilst this example doesn't filter child directory names, it could very easily be made recursive to support this, if you were so inclined.

Quick breakdown of how the snippet works

$folders << Uses Get-Childitem to query the file system and perform folder exclusion

$file << The pattern of the file I am looking for

foreach << Iterates the $folders variable performing a recursive search using the Get-Childitem command

$folders = Get-ChildItem -Path C:\ -Directory -Name -Exclude Folder1,"Folder 2"
$file = "*filenametosearchfor*.extension"

foreach ($folder in $folders) {
   Get-Childitem -Path "C:/$folder" -Recurse -Filter $file | ForEach-Object { Write-Output $_.FullName }
}

It should work ok as it is in Unix, if you have properties file in current working directory. Another option would be adding your properties file to the classpath and getting the inputstream using this.getClass().getClassLoader().getResourceAsStream("xxxxx.properties"); More here

If you already have the document created with plenty of code snippets in it and you are racing against time (as I unfortunately was). Save the file as a .doc as opposed to .docx and voila! Worked for me. Phew!

NOTE: Obviously your document can't have fancy features from > word 2007.

NOTE 2: File size becomes bigger if this is a concern to you.

String s = "-1139627840";
BigInteger bg1 = new BigInteger(s);
System.out.println(bg1.abs());

Alternatively:

int i = -123;
System.out.println(Math.abs(i));

There is already a solution provided which allows building a dictionary, (or nested dictionary for more complex data), but if you wish to build an object, then perhaps try 'ObjDict'. This gives much more control over the json to be created, for example retaining order, and allows building as an object which may be a preferred representation of your concept.

pip install objdict first.

from objdict import ObjDict

data = ObjDict()
data.key = 'value'
json_data = data.dumps()

  mB[31] = (Button) findViewById(R.id.xS6);
  mBSpace = (Button) findViewById(R.id.xSpace);
  mBdone = (Button) findViewById(R.id.xDone);
  mBChange = (Button) findViewById(R.id.xChange);
  mBack = (Button) findViewById(R.id.xBack);
  mNum = (Button) findViewById(R.id.xNum);
  for (int i = 0; i < mB.length; i++)
   mB[i].setOnClickListener(this);
  mBSpace.setOnClickListener(this);
  mBdone.setOnClickListener(this);
  mBack.setOnClickListener(this);
  mBChange.setOnClickListener(this);
  mNum.setOnClickListener(this);

I assume that you're writing to the file, then close it (so the user can open it in Excel), and then, before re-opening it for append/write operations, you want to check that the file isn't still open in Excel?

This is how you could do that:

while True:   # repeat until the try statement succeeds
    try:
        myfile = open("myfile.csv", "r+") # or "a+", whatever you need
        break                             # exit the loop
    except IOError:
        input("Could not open file! Please close Excel. Press Enter to retry.")
        # restart the loop

with myfile:
    do_stuff()

Also if you want to do something like ClassB.Run("thing");, make sure the Method Run(); is static or you could call it like this: thing.Run("thing");.

Try specifying exactly the modal that the button should close with data-target. So your button should look like the following -

<button class="close" data-dismiss="modal" data-target="#myModal">×</button>

Also, you should only need bootstrap.modal.js so you can safely remove the others.

Edit: if this doesn't work then remove the visible-phone class and test it on your PC browser instead of the phone. This will show whether you are getting javascript errors or if its a compatibility issue for example.

Make sure all your tables have one primary key. I forgot to add a primary key to one table and that solved this problem for me. :)

Note that backslashes (\) and dollar signs ($) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string; see Matcher.replaceAll. Use Matcher.quoteReplacement(java.lang.String) to suppress the special meaning of these characters, if desired.

from javadoc.

This is implementation of methods after decompiling.

    public static bool IsNullOrEmpty(String value) 
    {
        return (value == null || value.Length == 0); 
    }

    public static bool IsNullOrWhiteSpace(String value) 
    {
        if (value == null) return true; 

        for(int i = 0; i < value.Length; i++) { 
            if(!Char.IsWhiteSpace(value[i])) return false; 
        }

        return true;
    }

So it is obvious that IsNullOrWhiteSpace method also checks if value that is being passed contain white spaces.

Use git clone with the --depth option set to 1 to create a shallow clone with a history truncated to the latest commit.

For example:

git clone --depth 1 https://github.com/user/repo.git

To also initialize and update any nested submodules, also pass --recurse-submodules and to clone them shallowly, also pass --shallow-submodules.

For example:

git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git

Using the same as approach as Romeo, I adapted it to Visual Studio 2010 :

 <None Condition=" '$(Configuration)' == 'Debug' " Include="appDebug\App.config" />

 <None Condition=" '$(Configuration)' == 'Release' " Include="appRelease\App.config" />

Here you need to keep both App.config files in different directories (appDebug and appRelease). I tested it and it works fine!

Git requires a commit to have a comment, otherwise it wont accept the commit.

You can configure a default template with git as your default commit message or can look up the --allow-empty-message flag in git. I think (not 100% sure) you can reconfigure git to accept empty commit messages (which isn´t such a good idea). Normally each commit should be a bit of work which is described by your message.

First and foremost, I highly suggest using a profiler or atleast use timeit.

However if you wanted to write your own timing method strictly to learn, here is somewhere to get started using a decorator.

Python 2:

def timing(f):
    def wrap(*args):
        time1 = time.time()
        ret = f(*args)
        time2 = time.time()
        print '%s function took %0.3f ms' % (f.func_name, (time2-time1)*1000.0)
        return ret
    return wrap

And the usage is very simple, just use the @timing decorator:

@timing
def do_work():
  #code

Python 3:

def timing(f):
    def wrap(*args, **kwargs):
        time1 = time.time()
        ret = f(*args, **kwargs)
        time2 = time.time()
        print('{:s} function took {:.3f} ms'.format(f.__name__, (time2-time1)*1000.0))

        return ret
    return wrap

Note I'm calling f.func_name to get the function name as a string(in Python 2), or f.__name__ in Python 3.

You could use CSS to attain this. By specifying the list in the color and style of your choice, you can then also specify the text as a different color.

Follow the example at http://www.echoecho.com/csslists.htm.

I agree that mysql_result is the easy way to retrieve contents of one cell from a MySQL result set. Tiny code:

$r = mysql_query('SELECT id FROM table') or die(mysql_error());
if (mysql_num_rows($r) > 0) {
    echo mysql_result($r); // will output first ID
    echo mysql_result($r, 1); // will ouput second ID
}

Just a head's up, Skype will sometimes listen on port 80 and therefore cause this error if you try to listen on port 80 from Node.js or any other app.

You can turn off that behaviour in Skype by accessing the options and clicking Advanced -> Connection -> Use port 80 (Untick this)

P.S. After making that change, don't forget to restart Skype!

SQLite is database engine, .sqlite or .db should be a database. If you don't need to program anything, you can use a GUI like sqlitebrowser or anything like that to view the database contents.

Use showWarnings = FALSE:

dir.create(file.path(mainDir, subDir), showWarnings = FALSE)
setwd(file.path(mainDir, subDir))

dir.create() does not crash if the directory already exists, it just prints out a warning. So if you can live with seeing warnings, there is no problem with just doing this:

dir.create(file.path(mainDir, subDir))
setwd(file.path(mainDir, subDir))

This will drop the outermost level from the hierarchical column index:

df = data.groupby(...).agg(...)
df.columns = df.columns.droplevel(0)

If you'd like to keep the outermost level, you can use the ravel() function on the multi-level column to form new labels:

df.columns = ["_".join(x) for x in df.columns.ravel()]

For example:

import pandas as pd
import pandas.rpy.common as com
import numpy as np

data = com.load_data('Loblolly')
print(data.head())
#     height  age Seed
# 1     4.51    3  301
# 15   10.89    5  301
# 29   28.72   10  301
# 43   41.74   15  301
# 57   52.70   20  301

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
print(df.head())
#       age     height           
#       sum        std       mean
# Seed                           
# 301    78  22.638417  33.246667
# 303    78  23.499706  34.106667
# 305    78  23.927090  35.115000
# 307    78  22.222266  31.328333
# 309    78  23.132574  33.781667

df.columns = df.columns.droplevel(0)
print(df.head())

yields

      sum        std       mean
Seed                           
301    78  22.638417  33.246667
303    78  23.499706  34.106667
305    78  23.927090  35.115000
307    78  22.222266  31.328333
309    78  23.132574  33.781667

Alternatively, to keep the first level of the index:

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
df.columns = ["_".join(x) for x in df.columns.ravel()]

yields

      age_sum   height_std  height_mean
Seed                           
301        78    22.638417    33.246667
303        78    23.499706    34.106667
305        78    23.927090    35.115000
307        78    22.222266    31.328333
309        78    23.132574    33.781667

Something like this lets you test your procedure on almost any client:

DECLARE 
  v_cur SYS_REFCURSOR;
  v_a   VARCHAR2(10);
  v_b   VARCHAR2(10);
BEGIN
  your_proc(v_cur);

  LOOP
    FETCH v_cur INTO v_a, v_b;
    EXIT WHEN v_cur%NOTFOUND;
    dbms_output.put_line(v_a || ' ' || v_b);
  END LOOP;
  CLOSE v_cur;
END;

Basically, your test harness needs to support the definition of a SYS_REFCURSOR variable and the ability to call your procedure while passing in the variable you defined, then loop through the cursor result set. PL/SQL does all that, and anonymous blocks are easy to set up and maintain, fairly adaptable, and quite readable to anyone who works with PL/SQL.

Another, albeit similar way would be to build a named procedure that does the same thing, and assuming the client has a debugger (like SQL Developer, PL/SQL Developer, TOAD, etc.) you could then step through the execution.

Oh, youngsters.... Here you are:

<div class="block">
    <a href="#">Some Content with a very long description. Could be a Loren Ipsum or something like that.</a>
    <span>
        <span class="r-b">A right-bottom-block with some information</span>
    </span>
    <span class="clearfix"></span>
</div>
<style>
    .block {
        border: #000 solid 1px;
    }

    .r-b {
        border: #f00 solid 1px;
        background-color: fuchsia;
        float: right;
        width: 33%
    }

    .clearfix::after {
        display: block;
        clear: both;
        content: "";
    }
</style>

No absolute position! Responsive! OldSchool

It iterates through the json objects, and searches each value you are concerned about, 'website', and if it equals "yahoo" you can then return that value or do whatever you like there. Right now it just logs that element to the console.

jsonObj.forEach(function (element, index) {
    if(element['website'] === 'yahoo'){
        console.log('found', element)   
    }
})

It would return NULL but if taken as BIGINT would show the number

When you execute a method (i.e. function assigned to an object), inside it you can use this variable to refer to this object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
obj.someMethod(); // logs true

If you assign a method from one object to another, its this variable refers to the new object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
  someProperty: false,_x000D_
  someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false

The same thing happens when you assign requestAnimationFrame method of window to another object. Native functions, such as this, has build-in protection from executing it in other context.

There is a Function.prototype.call() function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({}) gives TypeError: Illegal invocation. However, alert.call(window) works fine, because now alert is executed in its original scope.

If you use .call() with your object like that:

support.animationFrame.call(window, function() {});

it works fine, because requestAnimationFrame is executed in scope of window instead of your object.

However, using .call() every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind(). It has similar effect to .call(), but instead of calling the function, it creates a new function which will always be called in specified context. For example:

window.someProperty = true;_x000D_
var obj = {_x000D_
  someProperty: false,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true

The only downside of Function.prototype.bind() is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.

As you probably already figured out, you can use .bind() to always execute requestAnimationFrame in context of window. Your code could look like this:

var support = {
    animationFrame: (window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame).bind(window)
};

Then you can simply use support.animationFrame(function() {});.

You need to specify the minimum width of the field.

String.format("%" + numberOfSpaces + "s", ""); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

String.format("%" + numberOfSpaces + "s", "Hello"); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

Repair Permissions

After you have identified and fixed the underlying cause (see below), you'll want to repair the permissions:

cd /path/to/repo.git
sudo chgrp -R groupname .
sudo chmod -R g+rwX .
find . -type d -exec chmod g+s '{}' +

Note if you want everyone to be able to modify the repository, you don't need the chgrp and you will want to change the chmod to sudo chmod -R a+rwX .

If you do not fix the underlying cause, the error will keep coming back and you'll have to keep re-running the above commands over and over again.

Underlying Causes

The error could be caused by one of the following:

• The repository isn't configured to be a shared repository (see core.sharedRepository in git help config). If the output of:

  git config core.sharedRepository
  

  is not group or true or 1 or some mask, try running:

  git config core.sharedRepository group
  

  and then re-run the recursive chmod and chgrp (see "Repair Permissions" above).

• The operating system doesn't interpret a setgid bit on directories as "all new files and subdirectories should inherit the group owner".

  When core.sharedRepository is true or group, Git relies on a feature of GNU operating systems (e.g., every Linux distribution) to ensure that newly created subdirectories are owned by the correct group (the group that all of the repository's users are in). This feature is documented in the GNU coreutils documentation:

  ... [If] a directory's set-group-ID bit is set, newly created subfiles inherit the same group as the directory, and newly created subdirectories inherit the set-group-ID bit of the parent directory. ... [This mechanism lets] users share files more easily, by lessening the need to use chmod or chown to share new files.

  However, not all operating systems have this feature (NetBSD is one example). For those operating systems, you should make sure that all of your Git users have the same default group. Alternatively, you can make the repository world-writable by running git config core.sharedRepository world (but be careful—this is less secure).

• The file system doesn't support the setgid bit (e.g., FAT). ext2, ext3, ext4 all support the setgid bit. As far as I know, the file systems that don't support the setgid bit also don't support the concept of group ownership so all files and directories will be owned by the same group anyway (which group is a mount option). In this case, make sure all Git users are in the group that owns all the files in the file system.
• Not all of the Git users are in the same group that owns the repository directories. Make sure the group owner on the directories is correct and that all users are in that group.

Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).

Here's the code relevant for your GUESTS Table.

1. Create AUDIT Table.

    IF NOT EXISTS
          (SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[Audit]') 
                   AND OBJECTPROPERTY(id, N'IsUserTable') = 1)
           CREATE TABLE Audit 
                   (Type CHAR(1), 
                   TableName VARCHAR(128), 
                   PK VARCHAR(1000), 
                   FieldName VARCHAR(128), 
                   OldValue VARCHAR(1000), 
                   NewValue VARCHAR(1000), 
                   UpdateDate datetime, 
                   UserName VARCHAR(128))
    GO

2. CREATE an UPDATE Trigger on the GUESTS Table as follows.

    CREATE TRIGGER TR_GUESTS_AUDIT ON GUESTS FOR UPDATE
    AS
    
    DECLARE @bit INT ,
           @field INT ,
           @maxfield INT ,
           @char INT ,
           @fieldname VARCHAR(128) ,
           @TableName VARCHAR(128) ,
           @PKCols VARCHAR(1000) ,
           @sql VARCHAR(2000), 
           @UpdateDate VARCHAR(21) ,
           @UserName VARCHAR(128) ,
           @Type CHAR(1) ,
           @PKSelect VARCHAR(1000)
           
    
    --You will need to change @TableName to match the table to be audited. 
    -- Here we made GUESTS for your example.
    SELECT @TableName = 'GUESTS'
    
    -- date and user
    SELECT         @UserName = SYSTEM_USER ,
           @UpdateDate = CONVERT (NVARCHAR(30),GETDATE(),126)
    
    -- Action
    IF EXISTS (SELECT * FROM inserted)
           IF EXISTS (SELECT * FROM deleted)
                   SELECT @Type = 'U'
           ELSE
                   SELECT @Type = 'I'
    ELSE
           SELECT @Type = 'D'
    
    -- get list of columns
    SELECT * INTO #ins FROM inserted
    SELECT * INTO #del FROM deleted
    
    -- Get primary key columns for full outer join
    SELECT @PKCols = COALESCE(@PKCols + ' and', ' on') 
                   + ' i.' + c.COLUMN_NAME + ' = d.' + c.COLUMN_NAME
           FROM    INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk ,
    
                  INFORMATION_SCHEMA.KEY_COLUMN_USAGE c
           WHERE   pk.TABLE_NAME = @TableName
           AND     CONSTRAINT_TYPE = 'PRIMARY KEY'
           AND     c.TABLE_NAME = pk.TABLE_NAME
           AND     c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME
    
    -- Get primary key select for insert
    SELECT @PKSelect = COALESCE(@PKSelect+'+','') 
           + '''<' + COLUMN_NAME 
           + '=''+convert(varchar(100),
    coalesce(i.' + COLUMN_NAME +',d.' + COLUMN_NAME + '))+''>''' 
           FROM    INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk ,
                   INFORMATION_SCHEMA.KEY_COLUMN_USAGE c
           WHERE   pk.TABLE_NAME = @TableName
           AND     CONSTRAINT_TYPE = 'PRIMARY KEY'
           AND     c.TABLE_NAME = pk.TABLE_NAME
           AND     c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME
    
    IF @PKCols IS NULL
    BEGIN
           RAISERROR('no PK on table %s', 16, -1, @TableName)
           RETURN
    END

The WHEREs will probably take a little tweaking to get the correlated subqueries working properly, but the basic principle should be sound.

You will need to configure your Win7 PC as a Time Server, and then configure the RasPi to connect to it for NTP services.

Configure Win7 as authoritative time server. Configure RasPi time server lookup.

There are no auto incrementing features in Oracle for a column. You need to create a SEQUENCE object. You can use the sequence like:

insert into table(batch_id, ...) values(my_sequence.nextval, ...)

...to return the next number. To find out the last created sequence nr (in your session), you would use:

my_sequence.currval

This site has several complete examples on how to use sequences.

How about run a command line:

require('child_process').execSync('rm -rf /path/to/directory/*')

From the printf manpage:

l (ell) A following integer conversion corresponds to a long int or unsigned long int argument, or a following n conversion corresponds to a pointer to a long int argument, or a following c conversion corresponds to a wint_t argument, or a following s conversion corresponds to a pointer to wchar_t argument.

and

L A following a, A, e, E, f, F, g, or G conversion corresponds to a long double argument. (C99 allows %LF, but SUSv2 does not.)

So, you want %Le , not %le

Edit: Some further investigation seems to indicate that Mingw uses the MSVC/win32 runtime(for stuff like printf) - which maps long double to double. So mixing a compiler (like gcc) that provides a native long double with a runtime that does not seems to .. be a mess.

You could try this:

int lengthChar(const char* chararray) {
   int n = 0;
   while(chararray[n] != '\0')
     n ++;
   return n;  
}

Abstraction means to show only the necessary details to the client of the object

Actually that is encapsulation. also see the first part of the wikipedia article in order to not be confused by encapsulation and data hiding. http://en.wikipedia.org/wiki/Encapsulation_(object-oriented_programming)

keep in mind that by simply hiding all you class members 1:1 behind properties is not encapsulation at all. encapsulation is all about protecting invariants and hiding of implementation details.

here a good article about that. http://blog.ploeh.dk/2012/11/27/Encapsulationofproperties/ also take a look at the articles linked in that article.

classes, properties and access modifiers are tools to provide encapsulation in c#.

you do encapsulation in order to reduce complexity.

Abstraction is "the process of identifying common patterns that have systematic variations; an abstraction represents the common pattern and provides a means for specifying which variation to use" (Richard Gabriel).

Yes, that is a good definition for abstraction.

They are different concepts. Abstraction is the process of refining away all the unneeded/unimportant attributes of an object and keep only the characteristics best suitable for your domain.

Yes, they are different concepts. keep in mind that abstraction is actually the opposite of making an object suitable for YOUR domain ONLY. it is in order to make the object suitable for the domain in general!

if you have a actual problem and provide a specific solution, you can use abstraction to formalize a more generic solution that can also solve more problems that have the same common pattern. that way you can increase the re-usability for your components or use components made by other programmers that are made for the same domain, or even for different domains.

good examples are classes provided by the .net framework, for example list or collection. these are very abstract classes that you can use almost everywhere and in a lot of domains. Imagine if .net only implemented a EmployeeList class and a CompanyList that could only hold a list of employees and companies with specific properties. such classes would be useless in a lot of cases. and what a pain would it be if you had to re-implement the whole functionality for a CarList for example. So the "List" is ABSTRACTED away from Employee, Company and Car. The List by itself is an abstract concept that can be implemented by its own class.

Interfaces, abstract classes or inheritance and polymorphism are tools to provide abstraction in c#.

you do abstraction in order to provide reusability.

Escaping quotes in VB6 or VBScript strings is simple in theory although often frightening when viewed. You escape a double quote with another double quote.

An example:

"c:\program files\my app\app.exe"

If I want to escape the double quotes so I could pass this to the shell execute function listed by Joe or the VB6 Shell function I would write it:

escapedString = """c:\program files\my app\app.exe"""

How does this work? The first and last quotes wrap the string and let VB know this is a string. Then each quote that is displayed literally in the string has another double quote added in front of it to escape it.

It gets crazier when you are trying to pass a string with multiple quoted sections. Remember, every quote you want to pass has to be escaped.

If I want to pass these two quoted phrases as a single string separated by a space (which is not uncommon):

"c:\program files\my app\app.exe" "c:\documents and settings\steve"

I would enter this:

escapedQuoteHell = """c:\program files\my app\app.exe"" ""c:\documents and settings\steve"""

I've helped my sysadmins with some VBScripts that have had even more quotes.

It's not pretty, but that's how it works.

Update 2019: Using Fetch:

fetch('http://localhost/foo.txt')
  .then(response => response.text())
  .then((data) => {
    console.log(data)
  })

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

You could do like this too. It worked out for me.

<form action="ResultsDulith.php" id="intermediate" name="inputMachine[]" multiple="multiple" method="post">
    <select id="selectDuration" name="selectDuration[]" multiple="multiple"> 
        <option value="1 WEEK" >Last 1 Week</option>
        <option value="2 WEEK" >Last 2 Week </option>
        <option value="3 WEEK" >Last 3 Week</option>
         <option value="4 WEEK" >Last 4 Week</option>
          <option value="5 WEEK" >Last 5 Week</option>
           <option value="6 WEEK" >Last 6 Week</option>
    </select>
     <input type="submit"/> 
</form>

Then take the multiple selection from following PHP code below. It print the selected multiple values accordingly.

$shift=$_POST['selectDuration'];

print_r($shift);

My take on Lombok is that it merely provides shortcuts for writing bolilerplate Java code.
When it comes to using shortcuts for writing bolilerplate Java code, I would rely on such features provided by IDE -- like in Eclipse, we can go to menu Source > Generate Getters and Setters for generating getters and setters.
I would not rely on a library like Lombok for this:

1. It pollutes your code with an indirection layer of alternative syntax (read @Getter, @Setter, etc. annotations). Rather than learning an alternative syntax for Java, I would switch to any other language that natively provides Lombok like syntax.
2. Lombok requires the use of a Lombok supported IDE to work with your code. This dependency introduces a considerable risk for any non-trivial project. Does the open source Lombok project have enough resources to keep providing support for different versions of a wide range of Java IDE's available?
3. Does the open source Lombok project have enough resources to keep providing support for newer versions of Java that will be coming in future?
4. I also feel nervous that Lombok may introduce compatibility issues with widely used frameworks/libraries (like Spring, Hibernate, Jackson, JUnit, Mockito) that work with your byte code at runtime.

All in all I would not prefer to "spice up" my Java with Lombok.

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

Personally (and given what I know, i.e., Java and axis), I'd generate a Java data model from the .xsd files (Axis 2 can do this), and then add an interface to describe my web service that uses that model, and then generate a WSDL from that interface.

Because .NET has all these features as well, it must be possible to do all this in that ecosystem as well.

@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the + operator fails for strings in EL (which is correct), then just do:

<c:out value="abc${test}" />

Or if abc is to obtained from another scoped variable named ${resp}, then do:

<c:out value="${resp}${test}" />

You can implement it directly i all your window html elements.
Like this :

HTMLElement.prototype.appendFirst = function(childNode) {
    if (this.firstChild) {
        this.insertBefore(childNode, this.firstChild);
    }
    else {
        this.appendChild(childNode);
    }
};

For the bourne shell:

sh myscript.sh

For bash:

bash myscript.sh

Just it case here is Swift version of awesome Jakob Egger's approach:

import UIKit

private weak var currentFirstResponder: UIResponder?

extension UIResponder {

    static func firstResponder() -> UIResponder? {
        currentFirstResponder = nil
        UIApplication.sharedApplication().sendAction(#selector(self.findFirstResponder(_:)), to: nil, from: nil, forEvent: nil)
        return currentFirstResponder
    }

    func findFirstResponder(sender: AnyObject) {
        currentFirstResponder = self
    }

}

There are so many similar solutions which probably work. Below is a simple and working way to accomplish try/catch, with explanation in the comments.

#!/bin/bash

function a() {
  # do some stuff here
}
function b() {
  # do more stuff here
}

# this subshell is a scope of try
# try
(
  # this flag will make to exit from current subshell on any error
  # inside it (all functions run inside will also break on any error)
  set -e
  a
  b
  # do more stuff here
)
# and here we catch errors
# catch
errorCode=$?
if [ $errorCode -ne 0 ]; then
  echo "We have an error"
  # We exit the all script with the same error, if you don't want to
  # exit it and continue, just delete this line.
  exit $errorCode
fi

I have this grid class that can be used as a simple matrix if you don't need any mathematical operators.

/**

    public:

        size_t mNumColumns;
        std::vector<T> mData;

We can get KEY from VALUE. Below is a sample code_

 public class Main {
  public static void main(String[] args) {
    Map map = new HashMap();
    map.put("key_1","one");
    map.put("key_2","two");
    map.put("key_3","three");
    map.put("key_4","four");

    System.out.println(getKeyFromValue(map,"four"));
  }
  public static Object getKeyFromValue(Map hm, Object value) {
    for (Object o : hm.keySet()) {
      if (hm.get(o).equals(value)) {
        return o;
      }
    }
    return null;
  }
}

I hope this will help everyone.

All the parameters after ? can be accessed using $_GET array. So,

echo $_GET['email'];

will extract the emails from urls.

Yes it is true.

If you create two instance of your class

Test t1 = new Test();
Test t2 = new Test();

Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.

keytool -import -v -alias cacerts -keystore cacerts.jks -storepass changeit -file C:\cacerts.cer

   var messages = {};
//get input, select, textarea of form

      var name = $(this).attr('name');
      rules[name] = {};
      messages[name] = {};

      rules[name] = {required: true}; // set required true against every name
//apply more rules, you can also apply custom rules & messages

         rules[name].email = true;
         //messages[name].email = "Please provide valid email";
      }
      else if(name==='url'){
        rules[name].required = false; // url filed is not required
//add other rules & messages
      }
   });
//submit form and use above created global rules & messages array
   $('#formId').submit(function (e) {
            e.preventDefault();
        }).validate({

            }
        });
});

You can't update with a number greater than 1 for datatype number(2,2) is because, the first parameter is the total number of digits in the number and the second one (.i.e 2 here) is the number of digits in decimal part. I guess you can insert or update data < 1. i.e. 0.12, 0.95 etc.

Please check NUMBER DATATYPE in NUMBER Datatype.

Today I was checking some resources about the same question and I got an example very interesting.

It is possible to call the same method by GET and POST protocol, but you need to overload the parameters like that:

@using (Ajax.BeginForm("Index", "MyController", ajaxOptions, new { @id = "form-consulta" }))
{
//code
}

The action:

[ActionName("Index")]
public async Task<ActionResult> IndexAsync(MyModel model)
{
//code
}

By default a method without explicit protocol is GET, but in that case there is a declared parameter which allows the method works like a POST.

When GET is executed the parameter does not matter, but when POST is executed the parameter is required on your request.

Here you get all available services and their status in your local machine.

ServiceController[] services = ServiceController.GetServices();
foreach(ServiceController service in services)
{
    Console.WriteLine(service.ServiceName+"=="+ service.Status);
}

You can Compare your service with service.name property inside loop and you get status of your service. For details go with the http://msdn.microsoft.com/en-us/library/system.serviceprocess.servicecontroller.aspx also http://msdn.microsoft.com/en-us/library/microsoft.windows.design.servicemanager(v=vs.90).aspx

first use this:

LayoutInflater inflater = (LayoutInflater) Read_file.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Read file is current activity in which you want your context.

View layout = inflater.inflate(R.layout.your_layout_name,(ViewGroup)findViewById(R.id.layout_name_id));

then you can use this to find any element in layout.

ImageView myImage = (ImageView) layout.findViewById(R.id.my_image);

To change the end address property edit your wsdl file

<wsdl:definitions.......
  <wsdl:service name="serviceMethodName">
    <wsdl:port binding="tns:serviceMethodNameSoapBinding" name="serviceMethodName">
      <soap:address location="http://service_end_point_adress"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

It doesn't inherit from Element because not all event targets are elements.

From MDN:

Element, document, and window are the most common event targets, but other objects can be event targets too, for example XMLHttpRequest, AudioNode, AudioContext, and others.

Even the KeyboardEvent you're trying to use can occur on a DOM element or on the window object (and theoretically on other things), so right there it wouldn't make sense for evt.target to be defined as an Element.

If it is an event on a DOM element, then I would say that you can safely assume evt.target. is an Element. I don't think this is an matter of cross-browser behavior. Merely that EventTarget is a more abstract interface than Element.

I have the same problem with importing WinSCard.dll in my project. I deal with that importing directly from dll like this:

[DllImport("winscard.dll")]
public static extern int SCardEstablishContext(int dwScope, int pvReserved1, int pvReserved2, ref int phContext);

[DllImport("winscard.dll")]
public static extern int SCardReleaseContext(int phContext);

You could add this to separate project and then add a reference from your main project.

Also a little note: If you want to reduce the compilation-time, you can add the flag

-j2

to run two parallel builds at the same time. This might reduce it to viewing one movie ;)

You can download IE Driver (both 32 and 64-bit) from Selenium official site: http://docs.seleniumhq.org/download/

32 bit Windows IE

64 bit Windows IE

IE Driver is also available in the following site:

http://selenium-release.storage.googleapis.com/index.html

You can try:

SELECT id FROM your_table WHERE id = (SELECT MAX(id) FROM your_table)

Where id is a primary key of the your_table

Xcode > Preferences > Locations > Command Line Tools

Select the option matching your version of Xcode.

You can get the screenshot of a division and save it easily just using the below snippet. Here I'm used the entire body, you can choose the specific image/div elements just by putting the id/class names.

 html2canvas(document.getElementsByClassName("image-div")[0], {
  useCORS: true,
}).then(function (canvas) {
  var imageURL = canvas.toDataURL("image/png");
  let a = document.createElement("a");
  a.href = imageURL;
  a.download = imageURL;
  a.click();
});

I'd use Apache Commons:

import org.apache.commons.lang3.StringUtils;

private void getId(String pdfName){
    String[] tokens = StringUtils.split(pdfName, "-.");
}

It'll split on any of the specified separators, as opposed to StringUtils.splitByWholeSeparator(str, separator) which uses the complete string as a separator

For strings like that, for me the most comfortable way to do it is doubling the ' or ", as explained in the MySQL manual:

There are several ways to include quote characters within a string:

A “'” inside a string quoted with “'” may be written as “''”.

A “"” inside a string quoted with “"” may be written as “""”.

Precede the quote character by an escape character (“\”).

A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a

Strings quoted with “'” need no special treatment.

It is from http://dev.mysql.com/doc/refman/5.0/en/string-literals.html.

What you probably need to do is redirect the user after the POST / Form Handler script has been ran.

In PHP this is done like so...

<?php
// ... Handle $_POST data, maybe insert it into a database.
// Ok, $_POST data has been handled, redirect the user
header('Location:success.php');
die();
?>

... this should allow you to refresh the page without getting that "Send Data Again" warning.

You can even redirect to the same page (if that's what you're posting to) as the POST variables will not be sent in the headers (and thus not be there to re-POST on refresh)

just put the variable inside the if condition, if variable has any value it will return true else false.

if (response.photo){ // if you are checking for string use this if(response.photo == "") condition
 alert("Has Value");
}
else
{
 alert("No Value");
};

When something in the state has changed and you need to call a side effect (like a request to api - get, put, post, delete). So you need to call componentDidUpdate() because componentDidMount() is already called.

After calling side effect in componentDidUpdate(), you can set the state to new value based on the response data in the then((response) => this.setState({newValue: "here"})). Please make sure that you need to check prevProps or prevState to avoid infinite loop because when setting state to a new value, the componentDidUpdate() will call again.

There are 2 places to call a side effect for best practice - componentDidMount() and componentDidUpdate()

For HTTP things, the current choice should be: Requests- HTTP for Humans

Use the WebClient class in System.Net:

var json = new WebClient().DownloadString("url");

Keep in mind that WebClient is IDisposable, so you would probably add a using statement to this in production code. This would look like:

using (WebClient wc = new WebClient())
{
   var json = wc.DownloadString("url");
}
