Had the same issue installing angular material CDK:

npm install --save @angular/material @angular/cdk @angular/animations

Adding -dev like below worked for me:

npm install --save-dev @angular/material @angular/cdk @angular/animations

DisplayMember and ValueMember are mostly only useful if you're databinding to objects that have those properties defined. You would then need to add an instance of that object.

e.g.:

public class MyObject
{
     public string clan { get; set; }
     public int sifOsoba { get; set; }
     public MyObject(string aClan, int aSif0soba)
     {
        this.clan = aClan;
        this.sif0soba = aSif0soba;
     }

     public override string ToString() { return this.clan; }
 }

 ....

 list.Items.Add(new MyObject("hello", 5));

If you're binding it manually then you can use the example provided by goggles

We can hide the content inside a by using the following inline css:

<div style="visibility:hidden"></div>

for example:

<td><div style="visibility:hidden">Your Content Goes Here:</div></td>

For me I was getting the problem when deploying a geoserver WAR into tomcat 7

To fix it, I was on Java 7 and upgrading to Java 8.

This is running under a docker container. Tomcat 7.0.75 + Java 8 + Geos 2.10.2

filenames must sort correctly to combine correctly!

file1.bin file2.bin ... file10.bin wont work properly

file01.bin file02.bin ... file10.bin will work properly

c:>for %i in (file*.bin) do type %i >> onebinary.bin

Works for ascii or binary files.

You're calling write_file with arguments like this:

write_file(foo, bar)

But you haven't defined 'foo' correctly, or you have a typo in your code so that it's creating a new empty variable and passing it in.

The accepted answer does not remove text that could be before Here or after String. This will:

sed -e 's/.*Here\(.*\)String.*/\1/'

The main difference is the addition of .* immediately before Here and after String.

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

You must to wrap your following code into a block (Either method or static).

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

Use this Retrofit Client

class RetrofitClient2(context: Context) : OkHttpClient() {

    private var mContext:Context = context
    private var retrofit: Retrofit? = null

    val client: Retrofit?
        get() {
            val logging = HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)

            val client = OkHttpClient.Builder()
                    .connectTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
                    .readTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
                    .writeTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
            client.addInterceptor(logging)
            client.interceptors().add(AddCookiesInterceptor(mContext))

            val gson = GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").create()
            if (retrofit == null) {

                retrofit = Retrofit.Builder()
                        .baseUrl(Constants.URL)
                        .addConverterFactory(GsonConverterFactory.create(gson))
                        .client(client.build())
                        .build()
            }
            return retrofit
        }
}

I'm passing the JWT along with every request. Please don't mind the variable names, it's a bit confusing.

class AddCookiesInterceptor(context: Context) : Interceptor {
    val mContext: Context = context
    @Throws(IOException::class)
    override fun intercept(chain: Interceptor.Chain): Response {
        val builder = chain.request().newBuilder()
        val preferences = CookieStore().getCookies(mContext)
        if (preferences != null) {
            for (cookie in preferences!!) {
                builder.addHeader("Authorization", cookie)
            }
        }
        return chain.proceed(builder.build())
    }
}

When a number as a decimal it is usually a float in Python.

If you want to remove the decimal and keep it an integer (int). You can call the int() method on it like so...

>>> int(2.0)
2

However, int rounds down so...

>>> int(2.9)
2

If you want to round to the nearest integer you can use round:

>>> round(2.9)
3.0
>>> round(2.4)
2.0

And then call int() on that:

>>> int(round(2.9))
3
>>> int(round(2.4))
2

Please make sure that you don't do any network access on UI Thread, instead do it in Async Task

The reason why your application crashes on Android versions 3.0 and above, but works fine on Android 2.x is because since HoneyComb are much stricter about abuse against the UI Thread. For example, when an Android device running HoneyComb or above detects a network access on the UI thread, a NetworkOnMainThreadException will be thrown.

What is Git:

"Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency"

Git is a distributed peer-peer version control system. Each node in the network is a peer, storing entire repositories which can also act as a multi-node distributed back-ups. There is no specific concept of a central server although nodes can be head-less or 'bare', taking on a role similar to the central server in centralised version control systems.

What is GitHub:

"GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features."

Github provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project.

You do not need GitHub to use Git.

GitHub (and any other local, remote or hosted system) can all be peers in the same distributed versioned repositories within a single project.

Github allows you to:

• Share your repositories with others.
• Access other user's repositories.
• Store remote copies of your repositories (github servers) as backup of your local copies.

If a node is so unhealthy that the master can't get status from it -- Kubernetes may not be able to restart the node. And if health checks aren't working, what hope do you have of accessing the node by SSH?

In this case, you may have to hard-reboot -- or, if your hardware is in the cloud, let your provider do it.

For example, the AWS EC2 Dashboard allows you to right-click an instance to pull up an "Instance State" menu -- from which you can reboot/terminate an unresponsive node.

Before doing this, you might choose to kubectl cordon node for good measure. And you may find kubectl delete node to be an important part of the process for getting things back to normal -- if the node doesn't automatically rejoin the cluster after a reboot.

Why would a node become unresponsive? Probably some resource has been exhausted in a way that prevents the host operating system from handling new requests in a timely manner. This could be disk, or network -- but the more insidious case is out-of-memory (OOM), which Linux handles poorly.

To help Kubernetes manage node memory safely, it's a good idea to do both of the following:

• Reserve some memory for the system.
• Be very careful with (avoid) opportunistic memory specifications for your pods. In other words, don't allow different values of requests and limits for memory.

The idea here is to avoid the complications associated with memory overcommit, because memory is incompressible, and both Linux and Kubernetes' OOM killers may not trigger before the node has already become unhealthy and unreachable.

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

Subprocess module is a good module to launch subprocesses. You can use it to call shell commands as this:

subprocess.call(["ls","-l"]);
#basic syntax
#subprocess.call(args, *)

You can see its documentation here.

If you have your script written in some .sh file or a long string, then you can use os.system module. It is fairly simple and easy to call:

import os
os.system("your command here")
# or
os.system('sh file.sh')

This command will run the script once, to completion, and block until it exits.

You can simply write like this also:-

<a href="#!" onclick="function()">Delete User</a>

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

I used a form with a single submit button. Point the "action" attribute to the ID of the element that needs to be navigated to. Worked for me with just "#top" without needing to define an ID in my stylesheet:

<form action="#top">
    <button type="submit">Back to Top</button>
</form>

Maybe a couple extra lines than is desirable but it's a button, at least. I find this the most concise and descriptive way to go about it.

Parsing a string representation of a DateTime is a tricky thing because different cultures have different date formats. .Net is aware of these date formats and pulls them from your current culture (System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat) when you call DateTime.Parse(this.Text);

For example, the string "22/11/2009" does not match the ShortDatePattern for the United States (en-US) but it does match for France (fr-FR).

Now, you can either call DateTime.ParseExact and pass in the exact format string that you're expecting, or you can pass in an appropriate culture to DateTime.Parse to parse the date.

For example, this will parse your date correctly:

DateTime.Parse( "22/11/2009", CultureInfo.CreateSpecificCulture("fr-FR") );

Of course, you shouldn't just randomly pick France, but something appropriate to your needs.

What you need to figure out is what System.Threading.Thread.CurrentThread.CurrentCulture is set to, and if/why it differs from what you expect.

With Gson, you'd just need to do something like:

List<Video> videos = gson.fromJson(json, new TypeToken<List<Video>>(){}.getType());

You might also need to provide a no-arg constructor on the Video class you're deserializing to.

You can use native Promise in ES6, for exemple dealing with setTimeout:

enqueue(data) {

    const queue = this;
    // returns the Promise
    return new Promise(function (resolve, reject) {
        setTimeout(()=> {
                queue.source.push(data);
                resolve(queue); //call native resolve when finish
            }
            , 10); // resolve() will be called in 10 ms
    });

}

In this exemple, the Promise has no reason to fail, so reject() is never called.

If you are using Jenkins templates you could have additional VM settings defined in it and this might conflicting with your system VM settings

example your tempalate may have references such as these

 <mavenOpts>-Xms512m -Xmx1024m -Xss1024k -XX:MaxPermSize=1024m -Dmaven.test.failure.ignore=false</mavenOpts> 

Ensure to align these template entries with the VM setting of your system

If you are using Postegres and Rails 4+, then you have the option of using column type CITEXT, which will allow case insensitive queries without having to write out the query logic.

The migration:

def change
  enable_extension :citext
  change_column :products, :name, :citext
  add_index :products, :name, unique: true # If you want to index the product names
end

And to test it out you should expect the following:

Product.create! name: 'jOgGers'
=> #<Product id: 1, name: "jOgGers">

Product.find_by(name: 'joggers')
=> #<Product id: 1, name: "jOgGers">

Product.find_by(name: 'JOGGERS')
=> #<Product id: 1, name: "jOgGers">

I'm going to assume compiling the QuickFix package does not produce a setup.py file, but rather only compiles the Python bindings and relies on make install to put them in the appropriate place.

In this case, a quick and dirty fix is to compile the QuickFix source, locate the Python extension modules (you indicated on your system these end with a .so extension), and add that directory to your PYTHONPATH environmental variable e.g., add

export PYTHONPATH=~/path/to/python/extensions:PYTHONPATH

or similar line in your shell configuration file.

A more robust solution would include making sure to compile with ./configure --prefix=$HOME/.local. Assuming QuickFix knows to put the Python files in the appropriate site-packages, when you do make install, it should install the files to ~/.local/lib/pythonX.Y/site-packages, which, for Python 2.6+, should already be on your Python path as the per-user site-packages directory.

If, on the other hand, it did provide a setup.py file, simply run

python setup.py install --user

for Python 2.6+.

This issue is raised because now the compile SDK version must match the Android Support library's major version.

In my case i have the Android Support Library version 23, so i had to compile against the Android SDK version 23, and I had to change this in my build.gradle file:

Well some of you will need to install the SDK, Android 6.0 (API 23)

Unlike another programming languages, any variable declared outside any function automatically becomes global,

<script>

//declare global variable
var __foo = '123';

function __test(){
 //__foo is global and visible here
 alert(__foo);
}

//so, it will alert '123'
__test();

</script>

You problem is that you declare variable inside ready() function, which means that it becomes visible (in scope) ONLY inside ready() function, but not outside,

Solution: So just make it global, i.e declare this one outside $(document).ready(function(){});

simplest method is just the copy the text that you want to paste it in cmd and open cmd goto "properties"---> "option" tab----> check the (give tick mark) "quickEdit mode" and click "ok" .....now you can paste any text from clipboard by doing right click from ur mouse.

You'll need to open the workbook to refer to it.

Sub Setwbk()

    Dim wbk As Workbook

    Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
        Master Benchmark Data Sheet.xlsx")

End Sub

_{* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:}

Why do I have to "set" it?

Set is how VBA assigns object variables. Since a Range and a Workbook/Worksheet are objects, you must use Set with these.

You can use this

string.strip().split(":")

The WHATWG HTML spec has the exact algorithm for parsing a legacy color value: https://html.spec.whatwg.org/multipage/infrastructure.html#rules-for-parsing-a-legacy-colour-value.

The code Netscape Classic used for parsing color strings is open source: https://dxr.mozilla.org/classic/source/lib/layout/layimage.c#155.

For example, notice that each character is parsed as a hex digit and then is shifted into a 32-bit integer without checking for overflow. Only eight hex digits fit into a 32-bit integer, which is why only the last 8 characters are considered. After parsing the hex digits into 32-bit integers, they are then truncated into 8-bit integers by dividing them by 16 until they fit into 8-bit, which is why leading zeros are ignored.

Update: This code does not exactly match what is defined in the spec, but the only difference there is a few lines of code. I think it is these lines that was added (in Netscape 4):

if (bytes_per_val > 4)
{
    bytes_per_val = 4;
}

The Interface describes either a contract for a class or a new type. It is a pure Typescript element, so it doesn't affect Javascript.

A model, and namely a class, is an actual JS function which is being used to generate new objects.

I want to load JSON data from a URL and bind to the Interface/Model.

Go for a model, otherwise it will still be JSON in your Javascript.

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

Chrome and Safari has a restriction on using ajax with local resources. That's why it's throwing an error like

Origin null is not allowed by Access-Control-Allow-Origin.

Solution: Use firefox or upload your data to a temporary server. If you still want to use Chrome, start it with the below option;

--allow-file-access-from-files

More info how to add the above parameter to your Chrome: Right click the Chrome icon on your task bar, right click the Google Chrome on the pop-up window and click properties and add the above parameter inside the Target textbox under Shortcut tab. It will like as below;

C:\Users\XXX_USER\AppData\Local\Google\Chrome\Application\chrome.exe --allow-file-access-from-files

Hope this will help!

Sometimes you don't have the option of editing the php file to set $_GET to the parameters passed in, and sometimes you can't or don't want to install php-cgi.

I found this to be the best solution for that case:

php -r '$_GET["key"]="value"; require_once("script.php");' 

This avoids altering your php file and lets you use the plain php command. If you have php-cgi installed, by all means use that, but this is the next best thing. Thought this options was worthy of mention

the -r means run the php code in the string following. you set the $_GET value manually there, and then reference the file you want to run.

Its worth noting you should run this in the right folder, often but not always the folder the php file is in. Requires statements will use the location of your command to resolve relative urls, NOT the location of the file

Considering the particular column Amount in the above table is of integer type. The following would be a solution :

df['Amount'] = df.Amount.fillna(0).astype(int)

Similarly, you can fill it with various data types like float, str and so on.

In particular, I would consider datatype to compare various values of the same column.

Use ThenByDescending:

var hold = MyList.OrderBy(x => x.StartDate)
                 .ThenByDescending(x => x.EndDate)
                 .ToList();

You can also use query syntax and say:

var hold = (from x in MyList
           orderby x.StartDate, x.EndDate descending
           select x).ToList();

ThenByDescending is an extension method on IOrderedEnumerable which is what is returned by OrderBy. See also the related method ThenBy.

If you are at the root of your working directory, you can do git checkout -- . to check-out all files in the current HEAD and replace your local files.

You can also do git reset --hard to reset your working directory and replace all changes (including the index).

Here is my answer for a simple comparator tool

Use \Q to autoescape any potentially problematic characters in your variable.

if($text_to_search =~ m/\Q$search_string/) print "wee";

In my situation, the password must contain:

• At least one lower case.
• At least one upper case.
• At least one decimal.
• At least one special character.

Here is my code:

    private string CreatePassword(int len)
    {
        string[] valid = { "abcdefghijklmnopqrstuvwxyz", "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "1234567890", "!@#$%^&*()_+" };
        RNGCryptoServiceProvider rndGen = new RNGCryptoServiceProvider();

        byte[] random = new byte[len];
        int[] selected = new int[len];

        do
        {
            rndGen.GetNonZeroBytes(random);

            for (int i = 0; i < random.Length; i++)
            {
                selected[i] = random[i] % 4;
            }
        } 
        while(selected.Distinct().Count() != 4);

        rndGen.GetNonZeroBytes(random);

        string res = "";

        for(int i = 0; i<len; i++)
        {
            res += valid[selected[i]][random[i] % valid[selected[i]].Length];
        }
        return res;
    }

use strncpy to make sure you have no buffer overflow.

char name[]= "whatever_you_want";
strncpy( sara.first, name, sizeof(sara.first)-1 );
sara.first[sizeof(sara.first)-1] = 0;

SQL Query: (group by & count of distinct)

select city,count(distinct(emailId)) from TransactionDetails group by city;

Equivalent mongo query would look like this:

db.TransactionDetails.aggregate([ 
{$group:{_id:{"CITY" : "$cityName"},uniqueCount: {$addToSet: "$emailId"}}},
{$project:{"CITY":1,uniqueCustomerCount:{$size:"$uniqueCount"}} } 
]);

A VERY BAD CAVEAT : Division by Zero

in a 1/x fraction, up to x = 1e-323 it is inf but when x = 1e-324 or little it throws ZeroDivisionError

>>> 1/1e-323
inf

>>> 1/1e-324
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: float division by zero

It worked for me.

Class library is shared compiled code.

Shared project is shared source code.

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

In intellij8 I was using a specific plugin "Jar Tool" that is configurable and allows to pack a JAR archive.

1. Writing JSON Parser Class

   public class JSONParser {
   
       static InputStream is = null;
       static JSONObject jObj = null;
       static String json = "";
   
       // constructor
       public JSONParser() {}
   
       public JSONObject getJSONFromUrl(String url) {
   
           // Making HTTP request
           try {
               // defaultHttpClient
               DefaultHttpClient httpClient = new DefaultHttpClient();
               HttpPost httpPost = new HttpPost(url);
   
               HttpResponse httpResponse = httpClient.execute(httpPost);
               HttpEntity httpEntity = httpResponse.getEntity();
               is = httpEntity.getContent();
   
           } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
           } catch (ClientProtocolException e) {
               e.printStackTrace();
           } catch (IOException e) {
               e.printStackTrace();
           }
   
           try {
               BufferedReader reader = new BufferedReader(new InputStreamReader(
                       is, "iso-8859-1"), 8);
               StringBuilder sb = new StringBuilder();
               String line = null;
               while ((line = reader.readLine()) != null) {
                   sb.append(line + "\n");
               }
               is.close();
               json = sb.toString();
           } catch (Exception e) {
               Log.e("Buffer Error", "Error converting result " + e.toString());
           }
   
           // try parse the string to a JSON object
           try {
               jObj = new JSONObject(json);
           } catch (JSONException e) {
               Log.e("JSON Parser", "Error parsing data " + e.toString());
           }
   
           // return JSON String
           return jObj;
   
       }
   }
   

2. Parsing JSON Data
   Once you created parser class next thing is to know how to use that class. Below i am explaining how to parse the json (taken in this example) using the parser class.

   2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.

   // url to make request
   private static String url = "http://api.9android.net/contacts";
   
   // JSON Node names
   private static final String TAG_CONTACTS = "contacts";
   private static final String TAG_ID = "id";
   private static final String TAG_NAME = "name";
   private static final String TAG_EMAIL = "email";
   private static final String TAG_ADDRESS = "address";
   private static final String TAG_GENDER = "gender";
   private static final String TAG_PHONE = "phone";
   private static final String TAG_PHONE_MOBILE = "mobile";
   private static final String TAG_PHONE_HOME = "home";
   private static final String TAG_PHONE_OFFICE = "office";
   
   // contacts JSONArray
   JSONArray contacts = null;
   

   2.2. Use parser class to get JSONObject and looping through each json item. Below i am creating an instance of JSONParser class and using for loop i am looping through each json item and finally storing each json data in variable.

   // Creating JSON Parser instance
   JSONParser jParser = new JSONParser();
   
   // getting JSON string from URL
   JSONObject json = jParser.getJSONFromUrl(url);
   
       try {
       // Getting Array of Contacts
       contacts = json.getJSONArray(TAG_CONTACTS);
   
       // looping through All Contacts
       for(int i = 0; i < contacts.length(); i++){
           JSONObject c = contacts.getJSONObject(i);
   
           // Storing each json item in variable
           String id = c.getString(TAG_ID);
           String name = c.getString(TAG_NAME);
           String email = c.getString(TAG_EMAIL);
           String address = c.getString(TAG_ADDRESS);
           String gender = c.getString(TAG_GENDER);
   
           // Phone number is agin JSON Object
           JSONObject phone = c.getJSONObject(TAG_PHONE);
           String mobile = phone.getString(TAG_PHONE_MOBILE);
           String home = phone.getString(TAG_PHONE_HOME);
           String office = phone.getString(TAG_PHONE_OFFICE);
   
       }
   } catch (JSONException e) {
       e.printStackTrace();
   }
   

You can easily install update version if you use Anaconda by closing Spyder and then running the following command in a system terminal (Anaconda Prompt on Windows, xterm on Linux or Terminal.app on macOS):

conda install spyder= Your desire version

(For example, Version is 3.1)

conda install spyder=3.1

Or you can use pip with this command in a system terminal (cmd.exe on Windows, xterm on Linux or Terminal.app on macOS):

pip install --pre -U spyder

Note: Do not use this command if you are using Anaconda because it could break your installation.

A process has code, data, heap and stack segments. Now, the Instruction Pointer (IP) of a thread OR threads points to the code segment of the process. The data and heap segments are shared by all the threads. Now what about the stack area? What is actually the stack area? Its an area created by the process just for its thread to use... because stacks can be used in a much faster way than heaps etc. The stack area of the process is divided among threads, i.e. if there are 3 threads, then the stack area of the process is divided into 3 parts and each is given to the 3 threads. In other words, when we say that each thread has its own stack, that stack is actually a part of the process stack area allocated to each thread. When a thread finishes its execution, the stack of the thread is reclaimed by the process. In fact, not only the stack of a process is divided among threads, but all the set of registers that a thread uses like SP, PC and state registers are the registers of the process. So when it comes to sharing, the code, data and heap areas are shared, while the stack area is just divided among threads.

Now you can see both the pseudo-class rules and force them on elements.

To see the rules like :hover in the Styles pane click the small :hov text in the top right.

To force an element into :hover state, right click it and select :hover.

Check out this list of lightbox plugins, depending on your exact requirements you can find the plugin of your choice from there easier than asking here. If you need a specific lightbox which can do just about anything and everything, try NyroModal.

You can make a bookmark with this as the url:

javascript:
var cached_anchors = $$('a');
for (var i in cached_anchors) {
    var ca = cached_anchors[i];
    if(ca.href.search('sprite') < 0 && ca.href.search('.png') > -1 || ca.href.search('.gif') > -1 || ca.href.search('.jpg') > -1) {
        var a = document.createElement('a');
        a.href = ca.innerHTML;
        a.target = '_blank';

        var img = document.createElement('img');
        img.src = ca.innerHTML;
        img.style.maxHeight = '100px';

        a.appendChild(img);
        document.getElementsByTagName('body')[0].appendChild(a);
    }
}
document.getElementsByTagName('body')[0].removeChild(document.getElementsByTagName('table')[0]);
void(0);

Then just go to chrome://cache and then click your bookmark and it'll show you all the images.

I use these commands to solve it.

mkdir /usr/local/lib
mkdir /usr/local/lib/pkgconfig
brew link python

There is a great library that wraps many solutions so it even supports older browsers called jStorage

You can set an object

$.jStorage.set(key, value)

And retrieve it easily

value = $.jStorage.get(key)
value = $.jStorage.get(key, "default value")

        {
            data = (T)serializer.Deserialize(streamReader, typeof(T));
        }
        return data;
    }

    public static T CreateFromJsonString<T>(this String json)
    {
        T data;
        using (MemoryStream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(json)))
        {
            data = CreateFromJsonStream<T>(stream);
        }
        return data;
    }

    public static T CreateFromJsonFile<T>(this String fileName)
    {
        T data;
        using (FileStream fileStream = new FileStream(fileName, FileMode.Open))
        {
            data = CreateFromJsonStream<T>(fileStream);
        }
        return data;
    }
}

Deserializing is now as easy as writing:

MyType obj1 = aStream.CreateFromJsonStream<MyType>();
MyType obj2 = "{\"key\":\"value\"}".CreateFromJsonString<MyType>();
MyType obj3 = "data.json".CreateFromJsonFile<MyType>();

Hope it will help someone else.

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

Just been through this, the correct way to do it is to use:

1. OnClientClick
2. return false

as in the following example line of code:

<asp:LinkButton ID="lbtnNext" runat="server" OnClientClick="findAllOccurences(); return false;" />

A dangling pointer points to memory that has already been freed. The storage is no longer allocated. Trying to access it might cause a Segmentation fault.

Common way to end up with a dangling pointer:

char *func()
{
   char str[10];
   strcpy(str, "Hello!");
   return str; 
}
//returned pointer points to str which has gone out of scope. 

You are returning an address which was a local variable, which would have gone out of scope by the time control was returned to the calling function. (Undefined behaviour)

Another common dangling pointer example is an access of a memory location via pointer, after free has been explicitly called on that memory.

int *c = malloc(sizeof(int));
free(c);
*c = 3; //writing to freed location!

A memory leak is memory which hasn't been freed, there is no way to access (or free it) now, as there are no ways to get to it anymore. (E.g. a pointer which was the only reference to a memory location dynamically allocated (and not freed) which points somewhere else now.)

void func(){
    char *ch = malloc(10);
}
//ch not valid outside, no way to access malloc-ed memory

Char-ptr ch is a local variable that goes out of scope at the end of the function, leaking the dynamically allocated 10 bytes.

If by increasing the memory limit you have gotten rid of the error and your code now works, you'll need to take measures to decrease that memory usage. Here are a few things you could do to decrease it:

If you're reading files, read them line-by-line instead of reading in the complete file into memory. Look at fgets and SplFileObject::fgets. Upgrade to a new version of PHP if you're using PHP 5.3. PHP 5.4 and 5.5 use much less memory.

Avoid loading large datasets into in an array. Instead, go for processing smaller subsets of the larger dataset and, if necessary, persist your data into a database to relieve memory use.

Try the latest version or minor version of a third-party library (1.9.3 vs. your 1.8.2, for instance) and use whichever is more stable. Sometimes newer versions of libraries are written more efficiently.

If you have an uncommon or unstable PHP extension, try upgrading it. It might have a memory leak.

If you're dealing with large files and you simply can't read it line-by-line, try breaking the file into many smaller files and process those individually. Disable PHP extensions that you don't need.

In the problem area, unset variables which contain large amounts of data and aren't required later in the code.

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

one line of lazy code:

mEditText.getBackground().setColorFilter(Color.RED, PorterDuff.Mode.SRC_ATOP);

Just simple use

=Format(today(), "dd/MM/yyyy")

will solve your problem.

You can use a one-liner with DOCKER_HOST variable:

docker save app:1.0 | gzip | DOCKER_HOST=ssh://user@remotehost docker load

I found this method to be quite useful. However it will convert your date/time format to just date but never the less it does the job for what I need it for. (I just needed to display the date on a report, the time was irrelevant).

CAST(start_date AS DATE)

UPDATE

(Bear in mind I'm a trainee ;))

I figured an easier way to do this IF YOU'RE USING SSRS.

It's easier to actually change the textbox properties where the field is located in the report. Right click field>Number>Date and select the appropriate format!

The easiest way was to (prior to Java 8) use,

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

But SimpleDateFormat is not thread-safe. Neither java.util.Date. This will lead to leading to potential concurrency issues for users. And there are many problems in those existing designs. To overcome these now in Java 8 we have a separate package called java.time. This Java SE 8 Date and Time document has a good overview about it.

So in Java 8 something like below will do the trick (to format the current date/time),

LocalDateTime.now()
   .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

And one thing to note is it was developed with the help of the popular third party library joda-time,

The project has been led jointly by the author of Joda-Time (Stephen Colebourne) and Oracle, under JSR 310, and will appear in the new Java SE 8 package java.time.

But now the joda-time is becoming deprecated and asked the users to migrate to new java.time.

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project

Anyway having said that,

If you have a Calendar instance you can use below to convert it to the new java.time,

    Calendar calendar = Calendar.getInstance();
    long longValue = calendar.getTimeInMillis();         

    LocalDateTime date =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue), ZoneId.systemDefault());
    String formattedString = date.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(date.toString()); // 2018-03-06T15:56:53.634
    System.out.println(formattedString); // 2018-03-06 15:56:53.634

If you had a Date object,

    Date date = new Date();
    long longValue2 = date.getTime();

    LocalDateTime dateTime =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue2), ZoneId.systemDefault());
    String formattedString = dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(dateTime.toString()); // 2018-03-06T15:59:30.278
    System.out.println(formattedString);     // 2018-03-06 15:59:30.278

If you just had the epoch milliseconds,

LocalDateTime date =
        LocalDateTime.ofInstant(Instant.ofEpochMilli(epochLongValue), ZoneId.systemDefault());

javac doesn't actively prohibit this, but it does have a limitation that pretty much means that you'd never want to refer to a top-level class from another file unless it has the same name as the file it's in.

Suppose you have two files, Foo.java and Bar.java.

Foo.java contains:

• public class Foo

Bar.java contains:

• public class Bar
• class Baz

Let's also say that all of the classes are in the same package (and the files are in the same directory).

What happens if Foo.java refers to Baz but not Bar and we try to compile Foo.java? The compilation fails with an error like this:

Foo.java:2: cannot find symbol
symbol  : class Baz
location: class Foo
  private Baz baz;
          ^
1 error

This makes sense if you think about it. If Foo.java refers to Baz, but there is no Baz.java (or Baz.class), how can javac know what source file to look in?

If you instead tell javac to compile Foo.java and Bar.java at the same time, or even if you had previously compiled Bar.java (leaving the Baz.class where javac can find it) then this error goes away. This makes your build process feel very unreliable and flaky, however.

Because the actual limitation, which is more like "don't refer to a top-level class from another file unless it has the same name as the file it's in or you're also referring to a class that's in that same file that's named the same thing as the file" is kind of hard to follow, people usually go with the much more straightforward (though stricter) convention of just putting one top-level class in each file. This is also better if you ever change your mind about whether a class should be public or not.

Sometimes there really is a good reason why everybody does something in a particular way.

Here is a (hopefully) universal patch I developed to fix this problem for BootStrap V3. No special requirements other than plugging in the script.

$(':not(.panel) > [data-toggle="collapse"][data-parent]').click(function() {
    var parent = $(this).data('parent');
    var items = $('[data-toggle="collapse"][data-parent="' + parent + '"]').not(this);
    items.each(function() {
        var target = $(this).data('target') || '#' + $(this).prop('href').split('#')[1];
        $(target).filter('.in').collapse('hide');
    });
});

EDIT: Below is a simplified answer which still meets my needs, and I'm now using a delegated click handler:

$(document.body).on('click', ':not(.panel) > [data-toggle="collapse"][data-parent]', function() {
    var parent = $(this).data('parent');
    var target = $(this).data('target') || $(this).prop('hash');
    $(parent).find('.collapse.in').not(target).collapse('hide');
});

1).(expression1 | expression2), | operator will evaluate expression2 irrespective of whether the result of expression1 is true or false.

Example:

class Or 
{
    public static void main(String[] args) 
    {
        boolean b=true;

        if (b | test());
    }

    static boolean test()
    {
        System.out.println("No short circuit!");
        return false;
    }
}

2).(expression1 || expression2), || operator will not evaluate expression2 if expression1 is true.

Example:

class Or 
{
    public static void main(String[] args) 
    {
        boolean b=true;

        if (b || test())
        {
            System.out.println("short circuit!");
        }
    }

    static boolean test()
    {
        System.out.println("No short circuit!");
        return false;
    }
}

Please find below example to load image using JavaFX.

    import javafx.application.Application;
    import javafx.scene.Scene;
    import javafx.scene.image.Image;
    import javafx.scene.image.ImageView;
    import javafx.scene.layout.StackPane;
    import javafx.stage.Stage;

    public class LoadImage extends Application {

    public static void main(String[] args) {
    Application.launch(args);
    }
    @Override
    public void start(Stage primaryStage) {
    primaryStage.setTitle("Load Image");

    StackPane sp = new StackPane();
    Image img = new Image("javafx.jpg");
    ImageView imgView = new ImageView(img);
    sp.getChildren().add(imgView);

    //Adding HBox to the scene
    Scene scene = new Scene(sp);
    primaryStage.setScene(scene);
    primaryStage.show();
    }

  }

Create one source folder with name Image in your project and add your image to that folder otherwise you can directly load image from external URL like following.

Image img = new Image("http://mikecann.co.uk/wp-content/uploads/2009/12/javafx_logo_color_1.jpg");

Personnaly, I simply do this :

HTML code:

<div>
    <table>
    </table>
</div>

CSS code:

div {
    display: inline;
}

If you apply a float on your div, it works too but obviously, you need to apply a "clear both" CSS rules at the next HTML element.

Using Java’s Float class.

float f = Float.parseFloat("25");
String s = Float.toString(25.0f);

To compare it's always better to convert the string to float and compare as two floats. This is because for one float number there are multiple string representations, which are different when compared as strings (e.g. "25" != "25.0" != "25.00" etc.)

you can use ExecuteScalar() in place of ExecuteNonQuery() to get a single result use it like this

Int32 result= (Int32) command.ExecuteScalar();
Console.WriteLine(String.Format("{0}", result));

It will execute the query, and returns the first column of the first row in the result set returned by the query. Additional columns or rows are ignored.

As you want only one row in return, remove this use of SqlDataReader from your code

using (SqlDataReader reader = command.ExecuteReader())
{
    // iterate your results here
    Console.WriteLine(String.Format("{0}",reader["id"]));
}

because it will again execute your command and effect your page performance.

Just add <br> where you would like to make the new line.

$S$: a set of shops
<br>
$I$: a set of items M wants to get

Because jupyter notebook markdown cell is a superset of HTML.
http://jupyter-notebook.readthedocs.io/en/latest/examples/Notebook/Working%20With%20Markdown%20Cells.html

Note that newlines using <br> does not persist when exporting or saving the notebook to a pdf (using "Download as > PDF via LaTeX"). It is probably treating each <br> as a space.

You can use the maps library to do this. Specifically, maps.FrozenMap

import maps
fm = maps.FrozenMap(my_dict)
hash(fm)

To install maps, just do:

pip install maps

It handles the nested dict case too:

import maps
fm = maps.FrozenMap.recurse(my_dict)
hash(fm)

Disclaimer: I am the author of the maps library.

Here is my solution (java 1.6), also would be interested why I had to do this:

I noticed from the javax.security.debug=ssl, that sometimes the used cipher suite is TLS_DHE_... and sometime it is TLS_ECDHE_.... The later would happen if I added BouncyCastle. If TLS_ECDHE_ was selected, MOST OF the time it worked, but not ALWAYS, so adding even BouncyCastle provider was unreliable (failed with same error, every other time or so). I guess somewhere in the Sun SSL implementation sometimes it choose DHE, sometimes it choose ECDHE.

So the solution posted here relies on removing TLS_DHE_ ciphers completely. NOTE: BouncyCastle is NOT required for the solution.

So create the server certification file by:

echo |openssl s_client -connect example.org:443 2>&1 |sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

Save this as it will be referenced later, than here is the solution for an SSL http get, excluding the TLS_DHE_ cipher suites.

I solve this by adding code into manifest:

<activity android:name=".Login"
        android:fitsSystemWindows="true"
        android:windowSoftInputMode="stateHidden|adjustPan"
</activity>

As a general advice, I would recommend not stealing the focus from the address bar. (Jeff already talked about that.)

Web page can take some time to load, which means that your focus change can occur some long time after the user typed the pae URL. Then he could have changed his mind and be back to url typing while you will be loading your page and stealing the focus to put it in your textbox.

That's the one and only reason that made me remove Google as my start page.

Of course, if you control the network (local network) or if the focus change is to solve an important usability issue, forget all I just said :)

This is the same as thefreeman but more in pythonic way using list and dictionary comprehension

columns = cursor.description 
result = [{columns[index][0]:column for index, column in enumerate(value)} for value in cursor.fetchall()]

pprint.pprint(result)

There are two reasons you might get this message:

1. ASP.Net is not configured. For this run from Administrator command %FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.
2. Another reason this may happen is because your App Pool is not configured correctly. For example, you created website for WordPress and you also want to throw in few aspx files in there, WordPress creates app pool that says don't run CLR stuff. To fix this just open up App Pool and enable CLR.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0]

In addition to the locations listed above, the OS X version of Perl also has two more ways:

6. The /Library/Perl/x.xx/AppendToPath file. Paths listed in this file are appended to @INC at runtime.

7. The /Library/Perl/x.xx/PrependToPath file. Paths listed in this file are prepended to @INC at runtime.

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

You can use the tag canvas and "draw" the background, which work on IE9, Gecko and Webkit.

If you still want a custom filter you can pass in the search model to the filter:

<article data-ng-repeat="result in results | cartypefilter:search" class="result">

Where definition for the cartypefilter can look like this:

app.filter('cartypefilter', function() {
  return function(items, search) {
    if (!search) {
      return items;
    }

    var carType = search.carType;
    if (!carType || '' === carType) {
      return items;
    }

    return items.filter(function(element, index, array) {
      return element.carType.name === search.carType;
    });

  };
});

The important point is that the list comprehension creates a new list. The generator creates a an iterable object that will "filter" the source material on-the-fly as you consume the bits.

Imagine you have a 2TB log file called "hugefile.txt", and you want the content and length for all the lines that start with the word "ENTRY".

So you try starting out by writing a list comprehension:

logfile = open("hugefile.txt","r")
entry_lines = [(line,len(line)) for line in logfile if line.startswith("ENTRY")]

This slurps up the whole file, processes each line, and stores the matching lines in your array. This array could therefore contain up to 2TB of content. That's a lot of RAM, and probably not practical for your purposes.

So instead we can use a generator to apply a "filter" to our content. No data is actually read until we start iterating over the result.

logfile = open("hugefile.txt","r")
entry_lines = ((line,len(line)) for line in logfile if line.startswith("ENTRY"))

Not even a single line has been read from our file yet. In fact, say we want to filter our result even further:

long_entries = ((line,length) for (line,length) in entry_lines if length > 80)

Still nothing has been read, but we've specified now two generators that will act on our data as we wish.

Lets write out our filtered lines to another file:

outfile = open("filtered.txt","a")
for entry,length in long_entries:
    outfile.write(entry)

Now we read the input file. As our for loop continues to request additional lines, the long_entries generator demands lines from the entry_lines generator, returning only those whose length is greater than 80 characters. And in turn, the entry_lines generator requests lines (filtered as indicated) from the logfile iterator, which in turn reads the file.

So instead of "pushing" data to your output function in the form of a fully-populated list, you're giving the output function a way to "pull" data only when its needed. This is in our case much more efficient, but not quite as flexible. Generators are one way, one pass; the data from the log file we've read gets immediately discarded, so we can't go back to a previous line. On the other hand, we don't have to worry about keeping data around once we're done with it.

There are multiple possible causes for this error:

1) When you put the property 'x' inside brackets you are trying to bind to it. Therefore first thing to check is if the property 'x' is defined in your component with an Input() decorator

Your html file:

<body [x]="...">

Your class file:

export class YourComponentClass {

  @Input()
  x: string;
  ...
}

(make sure you also have the parentheses)

2) Make sure you registered your component/directive/pipe classes in NgModule:

@NgModule({
  ...
  declarations: [
    ...,
    YourComponentClass
  ],
  ...
})

See https://angular.io/guide/ngmodule#declare-directives for more details about declare directives.

3) Also happens if you have a typo in your angular directive. For example:

<div *ngif="...">
     ^^^^^

Instead of:

<div *ngIf="...">

This happens because under the hood angular converts the asterisk syntax to:

<div [ngIf]="...">

Haven't you heard about the Comparable interface being implemented by String ? If no, try to use

"abcda".compareTo("abcza")

And it will output a good root for a solution to your problem.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

Try changing the Web Client request authentication part to:

NetworkCredential myCreds = new NetworkCredential(userName, passWord);
client.Credentials = myCreds;

Then make your call, seems to work fine for me.

Adding two more solutions to the problem:

• Use pylauncher (if you have Python 3.3 or newer there's no need to install it as it comes with Python already) and either add shebang lines to your scripts;

#! c:\[path to Python 2.5]\python.exe - for scripts you want to be run with Python 2.5
#! c:\[path to Python 2.6]\python.exe - for scripts you want to be run with Python 2.6

or instead of running python command run pylauncher command (py) specyfing which version of Python you want;

py -2.6 – version 2.6
py -2 – latest installed version 2.x
py -3.4 – version 3.4
py -3 – latest installed version 3.x

• Install virtualenv and create two virtualenvs;

virtualenv -p c:\[path to Python 2.5]\python.exe [path where you want to have virtualenv using Python 2.5 created]\[name of virtualenv]

virtualenv -p c:\[path to Python 2.6]\python.exe [path where you want to have virtualenv using Python 2.6 created]\[name of virtualenv]

for example

virtualenv -p c:\python2.5\python.exe c:\venvs\2.5

virtualenv -p c:\python2.6\python.exe c:\venvs\2.6

then you can activate the first and work with Python 2.5 like this
c:\venvs\2.5\activate
and when you want to switch to Python 2.6 you do

deactivate  
c:\venvs\2.6\activate

After opening the web.config file in application, add sample db connection in connectionStrings section like this:

<connectionStrings>  
    <add name="yourconnectinstringName" connectionString="Data Source= DatabaseServerName; Integrated Security=true;Initial Catalog= YourDatabaseName; uid=YourUserName; Password=yourpassword; " providerName="System.Data.SqlClient" />   
</connectionStrings>  

Declaring connectionStrings in web.config file:

 <add name="dbconnection" connectionString="Data Source=Soumalya;Integrated Security=true;Initial Catalog=MySampleDB" providerName="System.Data.SqlClient" />   

There is no need of username and password to access the database server. Now, write the code to get the connection string from web.config file in our codebehind file. Add the following namespace in codebehind file.

using System.Configuration;

This namespace is used to get configuration section details from web.config file.

using System;  
using System.Data.SqlClient;  
using System.Configuration;  
public partial class _Default: System.Web.UI.Page {  
    protected void Page_Load(object sender, EventArgs e) {  
        //Get connection string from web.config file  
        string strcon = ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString;  
        //create new sqlconnection and connection to database by using connection string from web.config file  
        SqlConnection con = new SqlConnection(strcon);  
        con.Open();  
    }  
}  

function myFunct( e ){
    e.preventDefault();

    var pastedText = undefined;
    if( window.clipboardData && window.clipboardData.getData ){
    pastedText = window.clipboardData.getData('Text');
} 
else if( e.clipboardData && e.clipboardData.getData ){
    pastedText = e.clipboardData.getData('text/plain');
}

//work with text

}
document.onpaste = myFunct;

If you don't have the Runnable references, on the first callback, get the obj of the message, and use removeCallbacksAndMessages() to remove all related callbacks.

Would this solution work?:

add following line to SceneDelegate: window.rootViewController?.view.backgroundColor = .black

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        if let windowScene = scene as? UIWindowScene {

                window.rootViewController?.view.backgroundColor = .black
}

Remove the characters ^ (start of string) and $ (end of string) from the regular expression.

var format = /[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]/;

No, you can't edit the connection string in the designer. The connection string is not part of the EDMX file it is just referenced value from the configuration file and probably because of that it is just readonly in the properties window.

Modifying configuration file is common task because you sometimes wants to make change without rebuilding the application. That is the reason why configuration files exist.

I solved the problem using the following trick when assigning shadow path for the container view :

[UIBezierPath bezierPathWithRoundedRect:cell.bounds cornerRadius:12]

Notice that the path given to the shadow is a rounded rectangle with the same corner radius as the background that the cell contains:

//this is the border for the UIView that is added to a cell
cell.backgroundView.layer.cornerRadius = 12;
cell.backgroundView.layer.masksToBounds = YES;
cell.backgroundView.layer.borderColor = [UIColor darkGrayColor].CGColor;
cell.backgroundView.layer.borderWidth = 1;

//this is the shadow around the cell itself (cannot have round corners with borders and shadow, need to use two views
cell.layer.shadowRadius = 2;
cell.layer.cornerRadius = 12;
cell.layer.masksToBounds = NO;
[[cell layer] setShadowColor:[[UIColor darkGrayColor] CGColor]];

[[cell layer] setShadowOffset:CGSizeMake(0.0,0.0)];
[[cell layer] setShadowOpacity:1.0];

UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:cell.bounds cornerRadius:12];
[[cell layer] setShadowPath:[path CGPath]];

@dannyeuu's answer is correct. pd.concat naturally does a join on index columns, if you set the axis option to 1. The default is an outer join, but you can specify inner join too. Here is an example:

x = pd.DataFrame({'a': [2,4,3,4,5,2,3,4,2,5], 'b':[2,3,4,1,6,6,5,2,4,2], 'val': [1,4,4,3,6,4,3,6,5,7], 'val2': [2,4,1,6,4,2,8,6,3,9]})
x.set_index(['a','b'], inplace=True)
x.sort_index(inplace=True)

y = x.__deepcopy__()
y.loc[(14,14),:] = [3,1]
y['other']=range(0,11)

y.sort_values('val', inplace=True)

z = x.__deepcopy__()
z.loc[(15,15),:] = [3,4]
z['another']=range(0,22,2)
z.sort_values('val2',inplace=True)


pd.concat([x,y,z],axis=1)

If you are directly working with matplotlib's pyplot (plt) and if you are more familiar with the new-style format string, you can try this:

from matplotlib.ticker import StrMethodFormatter
plt.gca().yaxis.set_major_formatter(StrMethodFormatter('{x:,.0f}')) # No decimal places
plt.gca().yaxis.set_major_formatter(StrMethodFormatter('{x:,.2f}')) # 2 decimal places

From the documentation:

class matplotlib.ticker.StrMethodFormatter(fmt)

Use a new-style format string (as used by str.format()) to format the tick.

The field used for the value must be labeled x and the field used for the position must be labeled pos.

I had this error message with boot2docker on windows with the docker-oracle-xe-11g image (https://registry.hub.docker.com/u/wnameless/oracle-xe-11g/).

The reason was that the virtual box disk was full (check with boot2docker.exe ssh df). Deleting old images and restarting the container solved the problem.

Simply add .. import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

imports: [ .. BrowserAnimationsModule

],

in app.module.ts file.

make sure you have installed .. npm install @angular/animations@latest --save

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add

Use display instead of visibility. display: none for invisible and no setting for visible.

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

.Text gives you a string representing what is displayed on the screen for the cell. Using .Text is usually a bad idea because you could get ####

.Value2 gives you the underlying value of the cell (could be empty, string, error, number (double) or boolean)

.Value gives you the same as .Value2 except if the cell was formatted as currency or date it gives you a VBA currency (which may truncate decimal places) or VBA date.

Using .Value or .Text is usually a bad idea because you may not get the real value from the cell, and they are slower than .Value2

For a more extensive discussion see my Text vs Value vs Value2

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

To answer the question How to delete specific columns in vba for excel. I use Array as below.

sub del_col()

dim myarray as variant
dim i as integer

myarray = Array(10, 9, 8)'Descending to Ascending
For i = LBound(myarray) To UBound(myarray)
    ActiveSheet.Columns(myarray(i)).EntireColumn.Delete
Next i

end sub

If your model is really "responsible" for the constants you should stick them there. You can create class methods to access them without creating a new object instance:

class Card < ActiveRecord::Base
  def self.colours
    ['white', 'blue']
  end
end

# accessible like this
Card.colours

Alternatively, you can create class variables and an accessor. This is however discouraged as class variables might act kind of surprising with inheritance and in multi-thread environments.

class Card < ActiveRecord::Base
  @@colours = ['white', 'blue'].freeze
  cattr_reader :colours
end

# accessible the same as above
Card.colours

The two options above allow you to change the returned array on each invocation of the accessor method if required. If you have true a truly unchangeable constant, you can also define it on the model class:

class Card < ActiveRecord::Base
  COLOURS = ['white', 'blue'].freeze
end

# accessible as
Card::COLOURS

You could also create global constants which are accessible from everywhere in an initializer like in the following example. This is probably the best place, if your colours are really global and used in more than one model context.

# put this into config/initializers/my_constants.rb
COLOURS = ['white', 'blue'].freeze

# accessible as a top-level constant this time
COLOURS

Note: when we define constants above, often we want to freeze the array. That prevents other code from later (inadvertently) modifying the array by e.g. adding a new element. Once an object is frozen, it can't be changed anymore.

If your branch is local only and hasn't been pushed to the server, use

git rebase master

Otherwise, use

git merge master

It is an abbreviation for 'optional' , used for optional software in some distros.

My example code was correct and the issue was something else in my actual code. Still, I know it was difficult to find examples of this so I'm answering it in case someone else is looking.

<div ng-repeat="f in foos">
  <div>
    <div ng-repeat="b in foos.bars">
      <a ng-click="addSomething($parent.$index)">Add Something</a>
    </div>
  </div>
</div>

Use setText(str) method of JLabel to dynamically change text displayed. In actionPerform of button write this:

jLabel.setText("new Value");

A simple demo code will be:

    JFrame frame = new JFrame("Demo");
    frame.setLayout(new BorderLayout());
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    frame.setSize(250,100);

    final JLabel label = new JLabel("flag");
    JButton button = new JButton("Change flag");
    button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent arg0) {
            label.setText("new value");
        }
    });

    frame.add(label, BorderLayout.NORTH);
    frame.add(button, BorderLayout.CENTER);
    frame.setVisible(true);

Here is the direct code that solves the OP's problem:

        Dim str As String = "the little red hen"

        Dim total As Int32

        Dim Target As String = "e"
        Dim Temp As Int32
        Dim Temp2 As Int32 = -1
Line50:
        Temp = str.IndexOf(Target, Temp2 + 1)
        Temp2 = Temp
        If Temp <> -1 Then

            ' Means there is a target there
            total = total + 1
            GoTo Line50
        End If

        MessageBox.Show(CStr(total))

Now, this is a handy function to solve the OP's problem:

    Public Function CountOccurrence(ByVal YourStringToCountOccurrence As String, ByVal TargetSingleCharacterToCount As String) As Int32
        Dim total As Int32

        Dim Temp As Int32
        Dim Temp2 As Int32 = -1
Line50:
        Temp = YourStringToCountOccurrence.IndexOf(TargetSingleCharacterToCount, Temp2 + 1)
        Temp2 = Temp
        If Temp <> -1 Then

            ' Means there is a target there
            total = total + 1
            GoTo Line50
        Else
            Return total
        End If
    End Function

Example of using the function:

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim str As String = "the little red hen"

    MessageBox.Show(CStr(CountOccurrence(str, "e")))
    ' It will return 4
End Sub

Here's a minimal answer that shows your example working:

    width: 200px;
    background-color: #ccc;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
    // this way works fine for Firefox, but 
    // Chrome and Safari can't do it.
    $("#coolDiv").animate({'left':0}, "slow");
    // So basically if you *start* with a right position
    // then stick to animating to another right position
    // to do that, get the window width minus the width of your div:
$("#coolDiv").animate({'right':($('body').innerWidth()-$('#coolDiv').width())}, 'slow');
    // sorry that's so ugly!
});
</script>
</head>
<body>
    <div style="" id="coolDiv">HELLO</div>

Original Answer:

You have:

$("#coolDiv").animate({"left":"0px", "slow");

Corrected:

$("#coolDiv").animate({"left":"0px"}, "slow");

They find a solution suboptimally without any guarantee as to the quality of solution found, it is obvious that it makes sense to the development of heuristics only polynomial. The application of these methods is suitable to solve real world problems or large problems so awkward from the computational point of view that for them there is not even an algorithm capable of finding an approximate solution in polynomial time.

With the following, it is easy to link the Cell address...

Can use address / substitute / Column functions as required to use Cell addresses in full DYNAMIC.

Decision tree between ES5, ES6 and TypeScript

Do you mind having a build step?

• Yes - Use ES5
• No - keep going

Do you want to use types?

• Yes - Use TypeScript
• No - Use ES6

More Details

ES5 is the JavaScript you know and use in the browser today it is what it is and does not require a build step to transform it into something that will run in today's browsers

ES6 (also called ES2015) is the next iteration of JavaScript, but it does not run in today's browsers. There are quite a few transpilers that will export ES5 for running in browsers. It is still a dynamic (read: untyped) language.

TypeScript provides an optional typing system while pulling in features from future versions of JavaScript (ES6 and ES7).

Note: a lot of the transpilers out there (i.e. babel, TypeScript) will allow you to use features from future versions of JavaScript today and exporting code that will still run in today's browsers.

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.

First, create your queue:

Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();

Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):

YourProducer producer = new YourProducer(queue);

and:

YourConsumer consumer = new YourConsumer(queue);

and add stuff to it in your producer:

queue.offer(myObject);

and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):

YourObject myObject = queue.poll();

For more info see the Javadoc

EDIT:

If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.

If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:

Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());

A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.

Finally:

Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:

BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();

queue.put(myObject); // Blocks until queue isn't full.

YourObject myObject = queue.take(); // Blocks until queue isn't empty.

Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.

This worked for me:

ActiveWindow.SmallScroll down:=0

or more simply:

ActiveWindow.SmallScroll 0

I had the same issue but it was because I copied and pasted the string as it is. Later when I manually typed the string as it is the error vanished.

I had the error due to the - sign. When I replaced it with manually inputting a - the error was solved.

Copied string 10 + 3 * 5/(16 - 4)

Manually typed string 10 + 3 * 5/(16 - 4)

you can clearly see there is a bit of difference between both the hyphens.

I think it's because of the different formatting used by different OS or maybe just different software.

I would suggest adding

(?!.*pass|.*word|.*1234|.*qwer|.*asdf) exclude common passwords

You should use NSError object.

let error = NSError(domain:"", code:401, userInfo:[ NSLocalizedDescriptionKey: "Invalid access token"])

Then cast NSError to Error object

Found other similar question, but not the answer.

It would have been interesting to know, where you have found this question.

As far as I can remember and according com.jcraft.jsch.JSchException: Auth cancel try to add to method .addIdentity() a passphrase. You can use "" in case you generated a keyfile without one. Another source of error is the fingerprint string. If it doesn't match you will get an authentication failure either (depends from on the target server).

And at last here my working source code - after I could solve the ugly administration tasks:

public void connect(String host, int port, 
                    String user, String pwd,
                    String privateKey, String fingerPrint,
                    String passPhrase
                  ) throws JSchException{
    JSch jsch = new JSch();

    String absoluteFilePathPrivatekey = "./";
    File tmpFileObject = new File(privateKey);
    if (tmpFileObject.exists() && tmpFileObject.isFile())
    {
      absoluteFilePathPrivatekey = tmpFileObject.getAbsolutePath();
    }

    jsch.addIdentity(absoluteFilePathPrivatekey, passPhrase);
    session = jsch.getSession(user, host, port);

    //Password and fingerprint will be given via UserInfo interface.
    UserInfo ui = new UserInfoImpl(pwd, fingerPrint);
    session.setUserInfo(ui);

    session.connect();

    Channel channel = session.openChannel("sftp");
    channel.connect();
    c = (ChannelSftp) channel;
}

Read this if you are populating your mat-select asyncronously via an http request.

If you are using a service to make an api call to return the mat-select options values, you must set the 'selected value' on your form control as part of the 'complete' section of your service api call subscribe().

For example:

  this.customerService.getCustomers().subscribe(
  customers => this.customers = customers ,
  error => this.errorMessage = error as any,
  () => this.customerSelectControl.setValue(this.mySelectedValue));

The standard way of using merge to undo the entire check-in works great, if that's what you want to do. Sometimes, though, all you want to do is revert a single file. There's no legitimate way to do that, but there is a hack:

1. Find the version that you want using svn log.

2. Use svn's export subcommand:

   svn export http://url-to-your-file@123 /tmp/filename

(Where 123 is the revision number for a good version of the file.) Then either move or copy that single file to overwrite the old one. Check in the modified file and you are done.

SELECT LASTNAME, COUNT(*)
FROM STUDENTS
GROUP BY LASTNAME
ORDER BY COUNT(*) DESC

I'd use a combination of the contains method and the toUpper method that are part of the String class. An example is below:

String string1 = "AAABBBCCC"; 
String string2 = "DDDEEEFFF";
String searchForThis = "AABB";

System.out.println("Search1="+string1.toUpperCase().contains(searchForThis.toUpperCase()));

System.out.println("Search2="+string2.toUpperCase().contains(searchForThis.toUpperCase()));

This will return:

Search1=true
Search2=false

The git diffs have an extra path segment prepended to the file paths. You can strip the this entry in the path by specifying -p1 with patch, like so:

patch -p1 < save.patch

<EditText
    android:id="@+id/txtDate"
    android:layout_width="140dp"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="10dp"
    android:layout_marginTop="2dp"
    android:clickable="false"
    android:cursorVisible="false"
    android:gravity="center" />

and use following :

txtDate.setKeyListener(null);

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1')
    }
}

You should first create a new environment in conda. From the terminal, type:

$ conda create --name my_env pandas ipython

Python will be installed automatically as part of this installation. After selecting [y] to confirm, you now need to activate this environment:

$ source activate my_env

On Windows I believe it is just:

$ activate my_env

Now, confirm installed packages:

$ conda list

Finally, start python and run your session.

$ ipython

var streetaddress = addy.substr(0, addy.indexOf('.')); 

(You should read through a javascript tutorial, esp. the part about String functions)

You can add New Symbol Image Set in .xcassets, then you can add SVG file in it

and use it same like image.

Note: This doesn't work on all SVG. You can have a look at the apple documentation

Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.

volatile and transient keywords

1) transient keyword is used along with instance variables to exclude them from serialization process. If a field is transient its value will not be persisted.

On the other hand, volatile keyword is used to mark a Java variable as "being stored in main memory".

Every read of a volatile variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.

2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

3) transient variables are initialized with default value during de-serialization and there assignment or restoration of value has to be handled by application code.

For more information, see my blog:
http://javaexplorer03.blogspot.in/2015/07/difference-between-volatile-and.html

You should just include header file(s).

If you include header file, header file automatically finds .cpp file. --> This process is done by LINKER.

Also, the best practice of moving your <script></script> to the bottom of the html file fixes this too.

Node's answer is really great, but it left open the question how can get stdout and stderr redirected. I found a solution on Unix & Linux, but it is also not complete. I would like to merge these two solutions. Here it is:

For my test I made a small bash script called loop.sh, which prints the pid of itself with a minute sleep in an infinite loop.

$./loop.sh

Now get the PID of this process somehow. Usually ps -C loop.sh is good enough, but it is printed in my case.

Now we can switch to another terminal (or press ^Z and in the same terminal). Now gdb should be attached to this process.

$ gdb -p <PID>

This stops the script (if running). Its state can be checked by ps -f <PID>, where the STAT field is 'T+' (or in case of ^Z 'T'), which means (man ps(1))

    T Stopped, either by a job control signal or because it is being traced
    + is in the foreground process group

(gdb) call close(1)
$1 = 0

Close(1) returns zero on success.

(gdb) call open("loop.out", 01102, 0600)
$6 = 1

Open(1) returns the new file descriptor if successful.

This open is equal with open(path, O_TRUNC|O_CREAT|O_RDWR, S_IRUSR|S_IWUSR). Instead of O_RDWR O_WRONLY could be applied, but /usr/sbin/lsof says 'u' for all std* file handlers (FD column), which is O_RDWR.

I checked the values in /usr/include/bits/fcntl.h header file.

The output file could be opened with O_APPEND, as nohup would do, but this is not suggested by man open(2), because of possible NFS problems.

If we get -1 as a return value, then call perror("") prints the error message. If we need the errno, use p errno gdb comand.

Now we can check the newly redirected file. /usr/sbin/lsof -p <PID> prints:

loop.sh <PID> truey    1u   REG   0,26        0 15008411 /home/truey/loop.out

If we want, we can redirect stderr to another file, if we want to using call close(2) and call open(...) again using a different file name.

Now the attached bash has to be released and we can quit gdb:

(gdb) detach
Detaching from program: /bin/bash, process <PID>
(gdb) q

If the script was stopped by gdb from an other terminal it continues to run. We can switch back to loop.sh's terminal. Now it does not write anything to the screen, but running and writing into the file. We have to put it into the background. So press ^Z.

^Z
[1]+  Stopped                 ./loop.sh

(Now we are in the same state as if ^Z was pressed at the beginning.)

Now we can check the state of the job:

$ ps -f 24522
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID><PPID>  0 11:16 pts/36   S      0:00 /bin/bash ./loop.sh
$ jobs
[1]+  Stopped                 ./loop.sh

So process should be running in the background and detached from the terminal. The number in the jobs command's output in square brackets identifies the job inside bash. We can use in the following built in bash commands applying a '%' sign before the job number :

$ bg %1
[1]+ ./loop.sh &
$ disown -h %1
$ ps -f <PID>
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID><PPID>  0 11:16 pts/36   S      0:00 /bin/bash ./loop.sh

And now we can quit from the calling bash. The process continues running in the background. If we quit its PPID become 1 (init(1) process) and the control terminal become unknown.

$ ps -f <PID>
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID>     1  0 11:16 ?        S      0:00 /bin/bash ./loop.sh
$ /usr/bin/lsof -p <PID>
...
loop.sh <PID> truey    0u   CHR 136,36                38 /dev/pts/36 (deleted)
loop.sh <PID> truey    1u   REG   0,26     1127 15008411 /home/truey/loop.out
loop.sh <PID> truey    2u   CHR 136,36                38 /dev/pts/36 (deleted)

COMMENT

The gdb stuff can be automatized creating a file (e.g. loop.gdb) containing the commands and run gdb -q -x loop.gdb -p <PID>. My loop.gdb looks like this:

call close(1)
call open("loop.out", 01102, 0600)
# call close(2)
# call open("loop.err", 01102, 0600)
detach
quit

Or one can use the following one liner instead:

gdb -q -ex 'call close(1)' -ex 'call open("loop.out", 01102, 0600)' -ex detach -ex quit -p <PID>

I hope this is a fairly complete description of the solution.

In MacOS, Mysql's executable file is located in /usr/local/mysql/bin/mysql and you can easily login to it with the following command:

/usr/local/mysql/bin/mysql -u USERNAME -p

But this is a very long command and very boring, so you can add mysql path to Os's Environment variable and access to it much easier.

For macOS Catalina and later

Starting with macOS Catalina, Mac devices use zsh as the default login shell and interactive shell and you have to update .zprofile file in your home directory.

echo 'export PATH="$PATH:/usr/local/mysql/bin"' >> ~/.zprofile
source ~/.zprofile
mysql -u USERNAME -p

For macOS Mojave and earlier

Although you can always switch to zsh, bash is the default shell in macOS Mojave and earlier and with bash you have to update .bash_profile file.

echo 'export PATH="$PATH:/usr/local/mysql/bin"' >> ~/.bash_profile
source ~/.bash_profile
mysql -u USERNAME -p

In jQuery, a new element can be created by passing a HTML string to the constructor, as shown below:

var img = $('<img id="dynamic">'); //Equivalent: $(document.createElement('img'))
img.attr('src', responseObject.imgurl);
img.appendTo('#imagediv');

You can trigger the mouseLeave event whenever you touch an element on touchscreen. Here is a solution for all <a> tags:

function removeHover() {
    var anchors = document.getElementsByTagName('a');
    for(i=0; i<anchors.length; i++) {
        anchors[i].addEventListener('touchstart', function(e){
            $('a').mouseleave();
        }, false);
    }
}

You need to use overflow option like below:

.nav{
    max-height: 300px;
    overflow-y: scroll; 
}

Change the height according to amount of items you need to show

I've seen your code in web.php as follows: Route::post('/edit/{id}','ProjectController@update');

Step 1: remove the {id} random parameter so it would be like this: Route::post('/edit','ProjectController@update');

Step 2: Then remove the @method('PUT') in your form, so let's say we'll just plainly use the POST method

Then how can I pass the ID to my method?

Step 1: make an input field in your form with the hidden attribute for example

<input type="hidden" value="{{$project->id}}" name="id">

Step 2: in your update method in your controller, fetch that ID for example:

$id = $request->input('id');

then you may not use it to find which project to edit

$project = Project::find($id)
//OR
$project = Project::where('id',$id);

[2017-07-25] since this continues to be the accepted answer, despite being a very hacky solution, I'm incorporating Gabi's code into it, leaving my own to serve as a bad example.

// my hacky approach:
function get_content() {
  var html = document.getElementById("txt").innerHTML;
  document.getElementById("txt").innerHTML = html.replace(/<[^>]*>/g, "");
}
// Gabi's elegant approach, but eliminating one unnecessary line of code:
function gabi_content() {
  var element = document.getElementById('txt');
  element.innerHTML = element.innerText || element.textContent;
}
// and exploiting the fact that IDs pollute the window namespace:
function txt_content() {
  txt.innerHTML = txt.innerText || txt.textContent;
}

.A {
  background: blue;
}

.B {
  font-style: italic;
}

.C {
  font-weight: bold;
}

<input type="button" onclick="get_content()" value="Get Content (bad)" />
<input type="button" onclick="gabi_content()" value="Get Content (good)" />
<input type="button" onclick="txt_content()" value="Get Content (shortest)" />
<p id='txt'>
  <span class="A">I am</span>
  <span class="B">working in </span>
  <span class="C">ABC company.</span>
</p>

Yes, your device can simultaneously connect to 7 other Bluetooth devices at the same time, in theory. Such a connection is called a piconet. A more complex connection pattern is the scatternet.

The reason it is limited to 7 other devices is because the assigned bit field for LT_ADDR in L2CAP protocol is only 3.

Not sure if this helps but in my app I had to check if a dictionary has changed.

Doing this will not work since basically it's still the same object:

val={'A':1,'B':2}
old_val=val

val['A']=10
if old_val != val:
  print('changed')

Using copy/deepcopy works:

import copy
val={'A':1,'B':2}
old_val=copy.deepcopy(val)

val['A']=10
if old_val != val:
  print('changed')

This should work in SQL Server:

update ud 
set assid = sale.assid
from sale
where sale.udid = id

You'll have to create a function for this. I don't think there is any built-in function for that purpose. All PHP arrays are associative by default. So, if you are unsure about their keys, here is the code:

<?php

$given_array = array('Monday' => 'boring',
'Friday' => 'yay',
'boring',
'Sunday' => 'fun',
7 => 'boring',
'Saturday' => 'yay fun',
'Wednesday' => 'boring',
'my life' => 'boring');

$repeating_value = "boring";

function array_value_positions($array, $value){
    $index = 0;
    $value_array = array();
        foreach($array as $v){
            if($value == $v){
                $value_array[$index] = $value;
            }
        $index++;
        }
    return $value_array;
}

$value_array = array_value_positions($given_array, $repeating_value);

$result = "The value '$value_array[0]' was found at these indices in the given array: ";

$key_string = implode(', ',array_keys($value_array));

echo $result . $key_string . "\n";//Output: The value 'boring' was found at these indices in the given array: 0, 2, 4, 6, 7

You need to create an event handler for the user control that is raised when an event from within the user control is fired. This will allow you to bubble the event up the chain so you can handle the event from the form.

When clicking Button1 on the UserControl, i'll fire Button1_Click which triggers UserControl_ButtonClick on the form:

User control:

[Browsable(true)] [Category("Action")] 
[Description("Invoked when user clicks button")]
public event EventHandler ButtonClick;

protected void Button1_Click(object sender, EventArgs e)
{
    //bubble the event up to the parent
    if (this.ButtonClick!= null)
        this.ButtonClick(this, e);               
}

Form:

UserControl1.ButtonClick += new EventHandler(UserControl_ButtonClick);

protected void UserControl_ButtonClick(object sender, EventArgs e)
{
    //handle the event 
}

Notes:

• Newer Visual Studio versions suggest that instead of if (this.ButtonClick!= null) this.ButtonClick(this, e); you can use ButtonClick?.Invoke(this, e);, which does essentially the same, but is shorter.

• The Browsable attribute makes the event visible in Visual Studio's designer (events view), Category shows it in the "Action" category, and Description provides a description for it. You can omit these attributes completely, but making it available to the designer it is much more comfortable, since VS handles it for you.

As everyone said, references can't be null. That is because, a reference refers to an object. In your code:

// this compiles, but doesn't work, and does this even mean anything?
if (&str == NULL)

you are taking the address of the object str. By definition, str exists, so it has an address. So, it cannot be NULL. So, syntactically, the above is correct, but logically, the if condition is always going to be false.

About your questions: it depends upon what you want to do. Do you want the function to be able to modify the argument? If yes, pass a reference. If not, don't (or pass reference to const). See this C++ FAQ for some good details.

In general, in C++, passing by reference is preferred by most people over passing a pointer. One of the reasons is exactly what you discovered: a reference can't be NULL, thus avoiding you the headache of checking for it in the function.

you can use the JSON.stringify() method found in modern browsers and provided by json2.js.

var myObj = {"myProp":"Hello"};
alert (JSON.stringify(myObj));    // alerts {"myProp":"Hello"};

or

also check this library : http://devpro.it/JSON/files/JSON-js.html

Here is a simple example. I suppose it will be easy to understand:

import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Graph extends JFrame {
JFrame f = new JFrame();
JPanel jp;


public Graph() {
    f.setTitle("Simple Drawing");
    f.setSize(300, 300);
    f.setDefaultCloseOperation(EXIT_ON_CLOSE);

    jp = new GPanel();
    f.add(jp);
    f.setVisible(true);
}

public static void main(String[] args) {
    Graph g1 = new Graph();
    g1.setVisible(true);
}

class GPanel extends JPanel {
    public GPanel() {
        f.setPreferredSize(new Dimension(300, 300));
    }

    @Override
    public void paintComponent(Graphics g) {
        //rectangle originates at 10,10 and ends at 240,240
        g.drawRect(10, 10, 240, 240);
        //filled Rectangle with rounded corners.    
        g.fillRoundRect(50, 50, 100, 100, 80, 80);
    }
}

}

And the output looks like this:

minrk's answer is right.

However, I found that the images appeared broken in Print View (on my Windows machine running the Anaconda distribution of IPython version 0.13.2 in a Chrome browser)

The workaround for this was to use <img src="../files/image.png"> instead.

This made the image appear correctly in both Print View and the normal iPython editing view.

UPDATE: as of my upgrade to iPython v1.1.0 there is no more need for this workaround since the print view no longer exists. In fact, you must avoid this workaround since it prevents the nbconvert tool from finding the files.

The difference is that in the first example, the program will block in the first line. The next line (console.log) will have to wait.

In the second example, the console.log will be executed WHILE the query is being processed. That is, the query will be processed in the background, while your program is doing other things, and once the query data is ready, you will do whatever you want with it.

So, in a nutshell: The first example will block, while the second won't.

The output of the following two examples:

// Example 1 - Synchronous (blocks)
var result = database.query("SELECT * FROM hugetable");
console.log("Query finished");
console.log("Next line");


// Example 2 - Asynchronous (doesn't block) 
database.query("SELECT * FROM hugetable", function(result) {
    console.log("Query finished");
});
console.log("Next line");

Would be:

1. Query finished
Next line
2. Next line
Query finished

Note
While Node itself is single threaded, there are some task that can run in parallel. For example, File System operations occur in a different process.

That's why Node can do async operations: one thread is doing file system operations, while the main Node thread keeps executing your javascript code. In an event-driven server like Node, the file system thread notifies the main Node thread of certain events such as completion, failure, or progress, along with any data associated with that event (such as the result of a database query or an error message) and the main Node thread decides what to do with that data.

You can read more about this here: How the single threaded non blocking IO model works in Node.js

for (int i = 0; i < clbIncludes.Items.Count; i++)
  if (clbIncludes.GetItemChecked(i))
    // Do selected stuff
  else
    // Do unselected stuff

If the the check is in indeterminate state, this will still return true. You may want to replace

if (clbIncludes.GetItemChecked(i))

with

if (clbIncludes.GetItemCheckState(i) == CheckState.Checked)

if you want to only include actually checked items.

Similarly in Java, you can create a S4 class in R that encapsulates your information:

setClass(Class="Person",
         representation(
            height="numeric",
            age="numeric"
          )
)

Then your function can return an instance of this class:

myFunction = function(age=28, height=176){
  return(new("Person",
          age=age,
          height=height))
}

and you can access your information:

aPerson = myFunction()

aPerson@age
aPerson@height

Typically you would accomplish this using an ajax request that looks like

var xhr = new XMLHttpRequest();
xhr.open("GET", "pythoncode.py?text=" + text, true);
xhr.responseType = "JSON";
xhr.onload = function(e) {
  var arrOfStrings = JSON.parse(xhr.response);
}
xhr.send();

You can build command using following example

 spark-submit    --jars /usr/share/java/postgresql-jdbc.jar    --class com.examples.WordCount3  /home/vaquarkhan/spark-scala-maven-project-0.0.1-SNAPSHOT.jar --jar  --num-executors 3 --driver-memory 10g **--executor-memory 10g** --executor-cores 1  --master local --deploy-mode client  --name wordcount3 --conf "spark.app.id=wordcount" 

To check input type

<!DOCTYPE html>
<html>
<body>

    <input type=number id="txtinp">
    <button onclick=checktype()>Try it</button>

    <script>
        function checktype() 
        {
            alert(document.getElementById("txtinp").type);
        }
    </script>

</body>
</html> 

Your code (vector1 == vector2) is correct C++ syntax. There is an == operator for vectors.

If you want to compare short vector with a portion of a longer vector, you can use theequal() operator for vectors. (documentation here)

Here's an example:

using namespace std;

if( equal(vector1.begin(), vector1.end(), vector2.begin()) )
    DoSomething();

Try this:

this.approved_by = IsNullOrEmpty(planRec.approved_by) ? "" : planRec.approved_by.toString();

You can also use the null-coalescing operator as other have said - since no one has given an example that works with your code here is one:

this.approved_by = planRec.approved_by ?? planRec.approved_by.toString();

But this example only works since a possible value for this.approved_by is the same as one of the potential values that you wish to set it to. For all other cases you will need to use the conditional operator as I showed in my first example.

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

See in your library projects make the compileSdkVersion and targetSdkVersion version to same level as your application is

android {
    compileSdkVersion 28

    defaultConfig {
        consumerProguardFiles 'proguard-rules.txt'
        minSdkVersion 14
        targetSdkVersion 28
    }
}

also make all dependencies to same level

All of these other answers include runtime overhead... like using ArrayList.toString().replaceAll(...) which are very wasteful.

I will give you the optimal algorithm with zero overhead; it doesn't look as pretty as the other options, but internally, this is what they are all doing (after piles of other hidden checks, multiple array allocation and other crud).

Since you already know you are dealing with strings, you can save a bunch of array allocations by performing everything manually. This isn't pretty, but if you trace the actual method calls made by the other implementations, you'll see it has the least runtime overhead possible.

public static String join(String separator, String ... values) {
  if (values.length==0)return "";//need at least one element
  //all string operations use a new array, so minimize all calls possible
  char[] sep = separator.toCharArray();

  // determine final size and normalize nulls
  int totalSize = (values.length - 1) * sep.length;// separator size
  for (int i = 0; i < values.length; i++) {
    if (values[i] == null)
      values[i] = "";
    else
      totalSize += values[i].length();
  }

  //exact size; no bounds checks or resizes
  char[] joined = new char[totalSize];
  int pos = 0;
  //note, we are iterating all the elements except the last one
  for (int i = 0, end = values.length-1; i < end; i++) {
    System.arraycopy(values[i].toCharArray(), 0, 
      joined, pos, values[i].length());
    pos += values[i].length();
    System.arraycopy(sep, 0, joined, pos, sep.length);
    pos += sep.length;
  }
  //now, add the last element; 
  //this is why we checked values.length == 0 off the hop
  System.arraycopy(values[values.length-1].toCharArray(), 0,
    joined, pos, values[values.length-1].length());

  return new String(joined);
}

In case if you are developing your own framework:

WHY is this happening?

If any of the public header files you have mentioned in your module.modulemap have import statements that are not mentioned in modulemap, this will give you the error. Since it tries to import some header that is not declared as modular (in module.modulemap), it breaks the modularity of the framework.

HOW can I fix it?

Just include the header that gave the error to your module.modulemap and build again!

WHY NOT just set allow non-modular to YES?

Because it's not really a solution here, with that you tell your project "this framework was supposed to be modular but it's not. Use it somehow, I don't care." This doesn't fix your library's modularity problem.

For people looking for getting text that is both centered and justified, the following should work:

<div class="center-justified">...lots and lots of text...</div>

With the following CSS rule (adjust the width property as needed):

.center-justified {
  text-align: justify;
  margin: 0 auto;
  width: 30em;
}

Here's the live demo.

What's going on?

1. text-align: justify; makes sure the text fills the full width of the div it is enclosed in.
2. margin: 0 auto; is actually a shorthand for four rules:
   • The first value is used for the margin-top and margin-bottom rules. The whole thing therefore means margin-top: 0; margin-bottom: 0, i.e. no margins above or below the div.
   • The second value is used for the margin-left and margin-right rules. So this rule results in margin-left: auto; margin-right: auto. This is the clever bit: it tells the browser to take whatever space is available on the sides and distribute it evenly on left and right. The result is centered text.
     However, this would not work without
3. width: 30em;, which limits the width of the div. Only when the width is restricted is there some whitespace left over for margin: auto to distribute. Without this rule the div would take up all available horizontal space, and you'd lose the centering effect.

session.query(Clients).filter(Clients.id == client_id_list).update({'status': status})
session.commit()

Try this =)

Swift 4.2 , In my case , using isKind function .

isKind(of:) Returns a Boolean value that indicates whether the receiver is an instance of given class or an instance of any class that inherits from that class.

  let items : [AnyObject] = ["A", "B" , ... ]
  for obj in items {
    if(obj.isKind(of: NSString.self)){
      print("String")
    }
  }

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

Sure, try:

input[value="United States"]{ color: red; }

This was answered in "Comparing ruby hashes". Rails adds a diff method to hashes. It works well.

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

The prompt command will echo text to the output:

prompt A useful comment.
select(*) from TableA;

Will be displayed as:

SQL> A useful comment.
SQL> 
  COUNT(*)
----------
     0

I know this is old, but it still comes up when you search for the comparison. We were using Mongo, have moved almost entirely to Dynamo, which is our first choice now. Not because it has more features, it doesn't. Mongo has a better query language, you can index within a structure, there's lots of little things. The superiority of Dynamo is in what the OP stated in his comment: it's easy. You don't have to take care of any servers. When you start to set up a Mongo sharded solution, it gets complicated. You can go to one of the hosting companies, but that's not cheap either. With Dynamo, if you need more throughput, you just click a button. You can write scripts to scale automatically. When it's time to upgrade Dynamo, it's done for you. That is all a lot of precious stress and time not spent. If you don't have dedicated ops people, Dynamo is excellent.

So we are now going on Dynamo by default. Mongo maybe, if the data structure is complicated enough to warrant it, but then we'd probably go back to a SQL database. Dynamo is obtuse, you really need to think about how you're going to build it, and likely you'll use Redis in Elasticcache to make it work for complex stuff. But it sure is nice to not have to take care of it. You code. That's it.

I've tested all anwers, but they were all too slow for me. If you have Excel installed you can use the COM.

I thought initially it would be slower since it will load everything for the actual Excel application, but it isn't for huge files. Maybe because the algorithm for opening and saving files runs a heavily optimized compiled code, Microsoft guys make a lot of money for it after all.

import sys
import os
import glob
from win32com.client import Dispatch

def main(path):
    excel = Dispatch("Excel.Application")
    if is_full_path(path):
        process_file(excel, path)
    else:
        files = glob.glob(path)
        for file_path in files:
            process_file(excel, file_path)
    excel.Quit()

def process_file(excel, path):
    fullpath = os.path.abspath(path)
    full_csv_path = os.path.splitext(fullpath)[0] + '.csv'
    workbook = excel.Workbooks.Open(fullpath)
    workbook.Worksheets(1).SaveAs(full_csv_path, 6)
    workbook.Saved = 1
    workbook.Close()


def is_full_path(path):
    return path.find(":") > -1

if __name__ == '__main__':
    main(sys.argv[1])

This is very raw code and won't check for errors, print help or anything, it will just create a csv file for each file that matches the pattern you entered in the function so you can batch process a lot of files only launching excel application once.

The Mockito javadoc seems to tell why use doReturn() instead of when() Use doReturn() in those rare occasions when you cannot use Mockito.when(Object).

Beware that Mockito.when(Object) is always recommended for stubbing because it is argument type-safe and more readable (especially when stubbing consecutive calls).

Here are those rare occasions when doReturn() comes handy:

1. When spying real objects and calling real methods on a spy brings side effects

List list = new LinkedList(); List spy = spy(list);

//Impossible: real method is called so spy.get(0) throws IndexOutOfBoundsException (the list is yet empty)

when(spy.get(0)).thenReturn("foo");

//You have to use doReturn() for stubbing: doReturn("foo").when(spy).get(0);

2. Overriding a previous exception-stubbing:

when(mock.foo()).thenThrow(new RuntimeException());

//Impossible: the exception-stubbed foo() method is called so RuntimeException is thrown. when(mock.foo()).thenReturn("bar");

//You have to use doReturn() for stubbing:

doReturn("bar").when(mock).foo(); Above scenarios shows a tradeoff of Mockito's elegant syntax. Note that the scenarios are very rare, though. Spying should be sporadic and overriding exception-stubbing is very rare. Not to mention that in general overridding stubbing is a potential code smell that points out too much stubbing.

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml

If you want to grow the array dynamically, you should use malloc() to dynamically allocate some fixed amount of memory, and then use realloc() whenever you run out. A common technique is to use an exponential growth function such that you allocate some small fixed amount and then make the array grow by duplicating the allocated amount.

Some example code would be:

size = 64; i = 0;
x = malloc(sizeof(words)*size); /* enough space for 64 words */
while (read_words()) {
    if (++i > size) {
        size *= 2;
        x = realloc(sizeof(words) * size);
    }
}
/* done with x */
free(x);

If you cannot find the .exe file, rebuild your solution and in your "Output" from Visual Studio the path to the file will be shown.

Build solution path.

The solution to the problem is:

1. Find the .gitconfig file

2. [user] name = 1wQasdTeedFrsweXcs234saS56Scxs5423 email = [email protected] [credential] helper = osxkeychain [url ""] insteadOf = git:// [url "https://"] [url "https://"] insteadOf = git://

there would be a blank url="" replace it with url="https://"

[user]
    name = 1wQasdTeedFrsweXcs234saS56Scxs5423
    email = [email protected]
[credential]
    helper = osxkeychain
[url "https://"]
    insteadOf = git://
[url "https://"]
[url "https://"]
    insteadOf = git://

This will work :)

Happy Bower-ing

Unfortunately, this is one of the many misnomers in the framework, or at best a violation of SRP.

To use the DateTimePicker for times, set the Format property to either Time or Custom (Use Custom if you want to control the format of the time using the CustomFormat property). Then set the ShowUpDown property to true.

Although a user may set the date and time together manually, they cannot use the GUI to set both.

i found this sollution at stackoverflow and i work for me although not working other sollutions if you have a windows 10 OS, doing the following steps will fix the problem:

1) go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Bin

2) then copy RC.exe and RcDll from this file

3) go to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin and paste the two files you have copied into it.

thats all i hope it is helpful...

As for your problem, currently you will have to depend on XHR or websockets for this.

Currently no popular browser has implemented any such raw sockets api for javascript that lets you create and access raw sockets, but a draft for the implementation of raw sockets api in JavaScript is under-way. Have a look at these links:
http://www.w3.org/TR/raw-sockets/
https://developer.mozilla.org/en-US/docs/Web/API/TCPSocket

Chrome now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment. Having said that, some developers are already creating interesting projects using it, such as this IRC client.

To access this API, you’ll need to enable the experimental flag in your extension’s manifest. Using sockets is pretty straightforward, for example:

chrome.experimental.socket.create('tcp', '127.0.0.1', 8080, function(socketInfo) {
  chrome.experimental.socket.connect(socketInfo.socketId, function (result) {
        chrome.experimental.socket.write(socketInfo.socketId, "Hello, world!");         
    });
});

$('button').toggle(
function() {
    $('#B').css('left', '0')
}, function() {
    $('#B').css('left', '200px')
})
