The guid provided is not correct format(.net Provided guid).

begin try
select convert(uniqueidentifier,'a89b1acd95016ae6b9c8aabb07da2010')
end try
begin catch
print '1'
end catch

I use GUIDs as random keys for database type operations.

The hexadecimal form, with the dashes and extra characters seem unnecessarily long to me. But I also like that strings representing hexadecimal numbers are very safe in that they do not contain characters that can cause problems in some situations such as '+','=', etc..

Instead of hexadecimal, I use a url-safe base64 string. The following does not conform to any UUID/GUID spec though (other than having the required amount of randomness).

import base64
import uuid

# get a UUID - URL safe, Base64
def get_a_uuid():
    r_uuid = base64.urlsafe_b64encode(uuid.uuid4().bytes)
    return r_uuid.replace('=', '')

You can use the hashlib library for Python. The shake_128 and shake_256 algorithms provide variable length hashes. Here's some working code (Python3):

import hashlib
>>> my_string = 'hello shake'
>>> hashlib.shake_256(my_string.encode()).hexdigest(5)
'34177f6a0a'

Notice that with a length parameter x (5 in example) the function returns a hash value of length 2x.

Security Notice: This solution should not be used in situations where the quality of your randomness can affect the security of an application. In particular, rand() and uniqid() are not cryptographically secure random number generators. See Scott's answer for a secure alternative.

If you do not need it to be absolutely unique over time:

md5(uniqid(rand(), true))

Otherwise (given you have already determined a unique login for your user):

md5(uniqid($your_user_login, true))

UUID schemes generally use not only a pseudo-random element, but also the current system time, and some sort of often-unique hardware ID if available, such as a network MAC address.

The whole point of using UUID is that you trust it to do a better job of providing a unique ID than you yourself would be able to do. This is the same rationale behind using a 3rd party cryptography library rather than rolling your own. Doing it yourself may be more fun, but it's typically less responsible to do so.

You can use identifierForVendor public property present in UIDevice class

let UUIDValue = UIDevice.currentDevice().identifierForVendor!.UUIDString
        print("UUID: \(UUIDValue)")

EDIT Swift 3:

UIDevice.current.identifierForVendor!.uuidString

END EDIT

Kindly check Column ApplicationId datatype in Table aspnet_Users , ApplicationId column datatype should be uniqueidentifier .

*Your parameter order is passed wrongly , Parameter @id should be passed as first argument, but in your script it is placed in second argument..*

So error is raised..

Please refere sample script:

DECLARE @id uniqueidentifier
SET @id = NEWID()
Create Table #temp1(AppId uniqueidentifier)

insert into #temp1 values(@id)

Select * from #temp1

Drop Table #temp1

UUID class

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

I use the following code to get the IMEI or use Secure.ANDROID_ID as an alternative, when the device doesn't have phone capabilities:

String identifier = null;
TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE));
if (tm != null)
      identifier = tm.getDeviceId();
if (identifier == null || identifier .length() == 0)
      identifier = Secure.getString(activity.getContentResolver(),Secure.ANDROID_ID);

There are three way to generate unique id in java.

1) the UUID class provides a simple means for generating unique ids.

 UUID id = UUID.randomUUID();
 System.out.println(id);

2) SecureRandom and MessageDigest

//initialization of the application
 SecureRandom prng = SecureRandom.getInstance("SHA1PRNG");

//generate a random number
 String randomNum = new Integer(prng.nextInt()).toString();

//get its digest
 MessageDigest sha = MessageDigest.getInstance("SHA-1");
 byte[] result =  sha.digest(randomNum.getBytes());

System.out.println("Random number: " + randomNum);
System.out.println("Message digest: " + new String(result));

3) using a java.rmi.server.UID

UID userId = new UID();
System.out.println("userId: " + userId);

I had the same problem and after a little research I decided the best would be to read MachineGuid in registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography, as @Agnus suggested. It is generated during OS installation and won't change unless you make another fresh OS install. Depending on the OS version it may contain the network adapter MAC address embedded (plus some other numbers, including random), or a pseudorandom number, the later for newer OS versions (after XP SP2, I believe, but not sure). If it's a pseudorandom theoretically it can be forged - if two machines have the same initial state, including real time clock. In practice, this will be rare, but be aware if you expect it to be a base for security that can be attacked by hardcore hackers.

Of course a registry entry can also be easily changed by anyone to forge a machine GUID, but what I found is that this would disrupt normal operation of so many components of Windows that in most cases no regular user would do it (again, watch out for hardcore hackers).

//Fields
String myID;
int myversion = 0;


myversion = Integer.valueOf(android.os.Build.VERSION.SDK);
if (myversion < 23) {
        TelephonyManager mngr = (TelephonyManager) 
getSystemService(Context.TELEPHONY_SERVICE);
        myID= mngr.getDeviceId();
    }
    else
    {
        myID = 
Settings.Secure.getString(getApplicationContext().getContentResolver(), 
Settings.Secure.ANDROID_ID);
    }

Yes, Secure.ANDROID_ID is unique for each device.

The OSHI project provides platform-independent hardware utilities.

Maven dependency:

<dependency>
    <groupId>com.github.oshi</groupId>
    <artifactId>oshi-core</artifactId>
    <version>LATEST</version>
</dependency>

For instance, you could use something like the following code to identify a machine uniquely:

import oshi.SystemInfo;
import oshi.hardware.CentralProcessor;
import oshi.hardware.ComputerSystem;
import oshi.hardware.HardwareAbstractionLayer;
import oshi.software.os.OperatingSystem;

class ComputerIdentifier
{
    static String generateLicenseKey()
    {
        SystemInfo systemInfo = new SystemInfo();
        OperatingSystem operatingSystem = systemInfo.getOperatingSystem();
        HardwareAbstractionLayer hardwareAbstractionLayer = systemInfo.getHardware();
        CentralProcessor centralProcessor = hardwareAbstractionLayer.getProcessor();
        ComputerSystem computerSystem = hardwareAbstractionLayer.getComputerSystem();

        String vendor = operatingSystem.getManufacturer();
        String processorSerialNumber = computerSystem.getSerialNumber();
        String processorIdentifier = centralProcessor.getIdentifier();
        int processors = centralProcessor.getLogicalProcessorCount();

        String delimiter = "#";

        return vendor +
                delimiter +
                processorSerialNumber +
                delimiter +
                processorIdentifier +
                delimiter +
                processors;
    }

    public static void main(String[] arguments)
    {
        String identifier = generateLicenseKey();
        System.out.println(identifier);
    }
}

Output for my machine:

Microsoft#57YRD12#Intel64 Family 6 Model 60 Stepping 3#8

Your output will be different since at least the processor serial number will differ.

I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.

If you want to use sha-256 (guid would be faster) then you would need to do something like

SHA256 shaAlgorithm = new SHA256Managed();
byte[] shaDigest = shaAlgorithm.ComputeHash(ASCIIEncoding.ASCII.GetBytes(url));
return BitConverter.ToString(shaDigest);

Of course, it doesn't have to ascii and it can be any other kind of hashing algorithm as well

You can pass a C# Guid value directly to a SQL Stored Procedure by specifying SqlDbType.UniqueIdentifier.

Your method may look like this (provided that your only parameter is the Guid):

public static void StoreGuid(Guid guid)
{
    using (var cnx = new SqlConnection("YourDataBaseConnectionString"))
    using (var cmd = new SqlCommand {
        Connection = cnx,
        CommandType = CommandType.StoredProcedure,
        CommandText = "StoreGuid",
        Parameters = {
            new SqlParameter {
                ParameterName = "@guid",
                SqlDbType = SqlDbType.UniqueIdentifier, // right here
                Value = guid
            }
        }
    })
    {
        cnx.Open();
        cmd.ExecuteNonQuery();
    }
}

I know this is an old question, but I shall post my answer for posterity...

It depends on the system that you are building and the particular business rules in place.

I am building a moderate to large scale CRM in MongoDb, C# (Backend API), and Angular (Frontend web app) and found ObjectId utterly terrible for use in Angular Routing for selecting particular entities. Same with API Controller routing.

The suggestion above worked perfectly for my project.

db.contacts.insert({
 "id":db.contacts.find().Count()+1,
 "name":"John Doe",
 "emails":[
    "[email protected]",
    "[email protected]"
 ],
 "phone":"555111322",
 "status":"Active"
});

The reason it is perfect for my case, but not all cases is that as the above comment states, if you delete 3 records from the collection, you will get collisions.

My business rules state that due to our in house SLA's, we are not allowed to delete correspondence data or clients records for longer than the potential lifespan of the application I'm writing, and therefor, I simply mark records with an enum "Status" which is either "Active" or "Deleted". You can delete something from the UI, and it will say "Contact has been deleted" but all the application has done is change the status of the contact to "Deleted" and when the app calls the respository for a list of contacts, I filter out deleted records before pushing the data to the client app.

Therefore, db.collection.find().count() + 1 is a perfect solution for me...

It won't work for everyone, but if you will not be deleting data, it works fine.

If you want to delete all duplicates, but one out of each set of duplicates, this is one solution:

DELETE posts
FROM posts
LEFT JOIN (
    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) = 1

    UNION

    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) != 1
) AS duplicate USING (id)
WHERE duplicate.id IS NULL;

For Abbreviated Month Names : "Aug"

DateTimeFormatInfo.GetAbbreviatedMonthName Method (Int32)

Returns the culture-specific abbreviated name of the specified month based on the culture associated with the current DateTimeFormatInfo object.

string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(8)

For Full Month Names : "August"

DateTimeFormatInfo.GetMonthName Method (Int32)

Returns the culture-specific full name of the specified month based on the culture associated with the current DateTimeFormatInfo object.

string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(8);

You should use setAlignmentX(..) on components you want to align, not on the container that has them..

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
panel.add(c1);
panel.add(c2);

c1.setAlignmentX(Component.LEFT_ALIGNMENT);
c2.setAlignmentX(Component.LEFT_ALIGNMENT);

The above answers seem to resolve the issue. If it doesn't, then you may also try to update conda using the following command.

conda update conda

And then try to install numpy using

conda install numpy

It seems that if

• Content-Type: application/json and
• if POST body isn't tightly bound to controller's input object class

Then MVC doesn't really bind the POST body to any particular class. Nor can you just fetch the POST body as a param of the ActionResult (suggested in another answer). Fair enough. You need to fetch it from the request stream yourself and process it.

[HttpPost]
public ActionResult Index(int? id)
{
    Stream req = Request.InputStream;
    req.Seek(0, System.IO.SeekOrigin.Begin);
    string json = new StreamReader(req).ReadToEnd();

    InputClass input = null;
    try
    {
        // assuming JSON.net/Newtonsoft library from http://json.codeplex.com/
        input = JsonConvert.DeserializeObject<InputClass>(json)
    }

    catch (Exception ex)
    {
        // Try and handle malformed POST body
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }

    //do stuff

}

Update:

for Asp.Net Core, you have to add [FromBody] attrib beside your param name in your controller action for complex JSON data types:

[HttpPost]
public ActionResult JsonAction([FromBody]Customer c)

Also, if you want to access the request body as string to parse it yourself, you shall use Request.Body instead of Request.InputStream:

Stream req = Request.Body;
req.Seek(0, System.IO.SeekOrigin.Begin);
string json = new StreamReader(req).ReadToEnd();

There's no easy way to do this, but something like this will work:

SELECT ET.TrainingID, 
  ET.CompletedDate, 
  ET.Notes
FROM 
HR_EmployeeTrainings ET
inner join
(
  select TrainingID, Max(CompletedDate) as CompletedDate
  FROM HR_EmployeeTrainings
  WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
  GROUP BY AvantiRecID, TrainingID  
) ET2 
  on ET.TrainingID = ET2.TrainingID
  and ET.CompletedDate = ET2.CompletedDate

Try not closing the connection before you send data to your database. Remove client.close(); from your code and it'll work fine.

Javascript isn't threaded, so a "wait" would freeze the entire page (and probably cause the browser to stop running the script entirely).

To specifically address your problem, you should remove the brackets after donothing in your setTimeout call, and make waitsecs a number not a string:

console.log('before');
setTimeout(donothing,500); // run donothing after 0.5 seconds
console.log('after');

But that won't stop execution; "after" will be logged before your function runs.

To wait properly, you can use anonymous functions:

console.log('before');
setTimeout(function(){
    console.log('after');
},500);

All your variables will still be there in the "after" section. You shouldn't chain these - if you find yourself needing to, you need to look at how you're structuring the program. Also you may want to use setInterval / clearInterval if it needs to loop.

I was looking for a way to format numbers without leading or trailing spaces, periods, zeros (except one leading zero for numbers less than 1 that should be present).

This is frustrating that such most usual formatting can't be easily achieved in Oracle.

Even Tom Kyte only suggested long complicated workaround like this:

case when trunc(x)=x
    then to_char(x, 'FM999999999999999999')
    else to_char(x, 'FM999999999999999.99')
end x

But I was able to find shorter solution that mentions the value only once:

rtrim(to_char(x, 'FM999999999999990.99'), '.')

This works as expected for all possible values:

select 
    to_char(num, 'FM99.99') wrong_leading_period,
    to_char(num, 'FM90.99') wrong_trailing_period,
    rtrim(to_char(num, 'FM90.99'), '.') correct
from (
  select num from (select 0.25 c1, 0.1 c2, 1.2 c3, 13 c4, -70 c5 from dual)
  unpivot (num for dummy in (c1, c2, c3, c4, c5))
) sampledata;

    | WRONG_LEADING_PERIOD | WRONG_TRAILING_PERIOD | CORRECT |
    |----------------------|-----------------------|---------|
    |                  .25 |                  0.25 |    0.25 |
    |                   .1 |                   0.1 |     0.1 |
    |                  1.2 |                   1.2 |     1.2 |
    |                  13. |                   13. |      13 |
    |                 -70. |                  -70. |     -70 |

Still looking for even shorter solution.

There is a shortening approarch with custom helper function:

create or replace function str(num in number) return varchar2
as
begin
    return rtrim(to_char(num, 'FM999999999999990.99'), '.');
end;

But custom pl/sql functions have significant performace overhead that is not suitable for heavy queries.

The code to do this without jQuery is trivial nowadays:

const frame = document.querySelector('iframe')
function syncHeight() {
  this.style.height = `${this.contentWindow.document.body.offsetHeight}px`
}
frame.addEventListener('load', syncHeight)

To unhook the event:

frame.removeEventListener('load', syncHeight)

REVISED - please see Andrew_1510's answer below, as IPython has been updated.

...

It was a bit hard figure out how to get there from a dusty bug report, but:

It ships with IPython now!

import ipy_autoreload
%autoreload 2
%aimport your_mod

# %autoreload? for help

... then every time you call your_mod.dwim(), it'll pick up the latest version.

TextView textView = (TextView) spinActSubTask.getSelectedView().findViewById(R.id.tvProduct);

String subItem = textView.getText().toString();

You can create another script file separately for the functions and invoke the script file whenever you want to call the function. This will help you to keep your code clean.

Function Definition : Create a new script file
Function Call       : Invoke the script file

0 * * * * cd folder_containing_exe && ./exe_name

should work unless there is something else that needs to be setup for the program to run.

import re
word = 'fubar'
regexp = re.compile(r'ba[rzd]')
if regexp.search(word):
  print 'matched'

There's an entire practice that says it's a bad idea to have inline functions/styles. Taking into account you already have an ID for your button, consider

JS

var myvar=15;
function init(){
    document.getElementById('EditBanner').onclick=function(){EditBanner(myvar);};
}
window.onload=init;

HTML

<input id="EditBanner" type="button"  value="Edit Image" />

If not work bad sertificate, when ServerCertificateValidationCallback return true; My ServerCertificateValidationCallback code:

ServicePointManager.ServerCertificateValidationCallback += delegate
{
    LogWriter.LogInfo("???????? ??????????? ?????????, ?? ?????? ServerCertificateValidationCallback");
    return true;
};

My code which the prevented execute ServerCertificateValidationCallback:

     if (!(ServicePointManager.CertificatePolicy is CertificateValidation))
    {
        CertificateValidation certValidate = new CertificateValidation();
        certValidate.ValidatingError += new CertificateValidation.ValidateCertificateEventHandler(this.OnValidateCertificateError);
        ServicePointManager.CertificatePolicy = certValidate;
    }

OnValidateCertificateError function:

private void OnValidateCertificateError(object sender, CertificateValidationEventArgs e)
{
    string msg = string.Format(Strings.OnValidateCertificateError, e.Request.RequestUri, e.Certificate.GetName(), e.Problem, new Win32Exception(e.Problem).Message);
    LogWriter.LogError(msg);
    //Message.ShowError(msg);
}

I disabled CertificateValidation code and ServerCertificateValidationCallback running very well

VBA functions treat the function name itself as a sort of variable. So instead of using a "return" statement, you would just say:

test = 1

Notice, though, that this does not break out of the function. Any code after this statement will also be executed. Thus, you can have many assignment statements that assign different values to test, and whatever the value is when you reach the end of the function will be the value returned.

A soft git reset will put committed changes back into your index. Next, checkout the branch you had intended to commit on. Then git commit with a new commit message.

1. git reset --soft <commit>

2. git checkout <branch>

3. git commit -m "Commit message goes here"

From git docs:

git reset [<mode>] [<commit>] This form resets the current branch head to and possibly updates the index (resetting it to the tree of ) and the working tree depending on . If is omitted, defaults to --mixed. The must be one of the following:

--soft Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

It's because you have a recursive function inside of rotate. It's calling itself again:

// Animate rotation with a recursive call
setTimeout(function() { rotate(++degree); },65);

Take that out and it won't keep on running recursively.

I would also suggest just using this function instead:

function rotate($el, degrees) {
    $el.css({
  '-webkit-transform' : 'rotate('+degrees+'deg)',
     '-moz-transform' : 'rotate('+degrees+'deg)',  
      '-ms-transform' : 'rotate('+degrees+'deg)',  
       '-o-transform' : 'rotate('+degrees+'deg)',  
          'transform' : 'rotate('+degrees+'deg)',  
               'zoom' : 1

    });
}

It's much cleaner and will work for the most amount of browsers.

For deleting files:

os.unlink(path, *, dir_fd=None)

or

os.remove(path, *, dir_fd=None)

Both functions are semantically same. This functions removes (deletes) the file path. If path is not a file and it is directory, then exception is raised.

For deleting folders:

shutil.rmtree(path, ignore_errors=False, onerror=None)

or

os.rmdir(path, *, dir_fd=None)

In order to remove whole directory trees, shutil.rmtree() can be used. os.rmdir only works when the directory is empty and exists.

For deleting folders recursively towards parent:

os.removedirs(name)

It remove every empty parent directory with self until parent which has some content

ex. os.removedirs('abc/xyz/pqr') will remove the directories by order 'abc/xyz/pqr', 'abc/xyz' and 'abc' if they are empty.

For more info check official doc: os.unlink , os.remove, os.rmdir , shutil.rmtree, os.removedirs

Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:

=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))

Get-ADGroupMember "Group1" -recursive | Select-Object Name | Export-Csv c:\path\Groups.csv

I got this to work for me... I would assume that you could put "Group1, Group2, etc." or try a wildcard. I did pre-load AD into PowerShell before hand:

Get-Module -ListAvailable | Import-Module

public void EndTask(string taskname)
{
      string processName = taskname.Replace(".exe", "");

      foreach (Process process in Process.GetProcessesByName(processName))
      {
          process.Kill();
      }
}

//EndTask("notepad");

Summary: no matter if the name contains .exe, the process will end. You don't need to "leave off .exe from process name", It works 100%.

This function converts a Blob into a File and it works great for me.

Vanilla JavaScript

function blobToFile(theBlob, fileName){
    //A Blob() is almost a File() - it's just missing the two properties below which we will add
    theBlob.lastModifiedDate = new Date();
    theBlob.name = fileName;
    return theBlob;
}

TypeScript (with proper typings)

public blobToFile = (theBlob: Blob, fileName:string): File => {
    var b: any = theBlob;
    //A Blob() is almost a File() - it's just missing the two properties below which we will add
    b.lastModifiedDate = new Date();
    b.name = fileName;

    //Cast to a File() type
    return <File>theBlob;
}

Usage

var myBlob = new Blob();

//do stuff here to give the blob some data...

var myFile = blobToFile(myBlob, "my-image.png");

Try explicitly enumerating the results by calling ToList().

Change

foreach (var item in query)

to

foreach (var item in query.ToList())

For me, none of these answers worked, but I finally found one that did.

I needed this for IE-

$('input:text').attr("disabled", 'disabled');

I also had to add this for Chrome and Firefox -

$('input:text').AddClass("notactive");

and this -

<style type="text/css">
    .notactive {
        pointer-events: none;
        cursor: default;
    }
 </style>

SingleOrDefault() is what you need

cheers

Another important point

JAX-WS represents SOAP

JAX-RS represents REST

How to choose between JAX-RS and JAX-WS web services implementation?

I think that Alex Martelli's answer is definitely the most elegant way to do this, but just wanted to add a way to satisfy your want for a super awesome dictionary.filter(f) method in a Pythonic sort of way:

class FilterDict(dict):
    def __init__(self, input_dict):
        for key, value in input_dict.iteritems():
            self[key] = value
    def filter(self, criteria):
        for key, value in self.items():
            if (criteria(value)):
                self.pop(key)

my_dict = FilterDict( {'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} )
my_dict.filter(lambda x: x[0] < 5 and x[1] < 5)

Basically we create a class that inherits from dict, but adds the filter method. We do need to use .items() for the the filtering, since using .iteritems() while destructively iterating will raise exception.

With Protractor, you can use the following approach

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain newPageName
browser.wait(EC.urlContains('newPageName'), 10000);

So your code will look something like,

emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');

btnLoginEl.click();

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain efg
ptor.wait(EC.urlContains('efg'), 10000);

expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');

Note: This may not mean that new page has finished loading and DOM is ready. The subsequent 'expect()' statement will ensure Protractor waits for DOM to be available for test.

Reference: Protractor ExpectedConditions

While I agree with the comments about passing in variables from your controller you can also register undefined functions when setting up the twig environment

$twig->registerUndefinedFunctionCallback(function ($name) {
        // security
        $allowed = false;
        switch ($name) {
            // example of calling a wordpress function
            case 'get_admin_page_title':
                $allowed = true;
                break;
        }

        if ($allowed && function_exists($name)) {
            return new Twig_Function_Function($name);
        }

        return false;
    });

This is from the Twig recipe page

Haven't tried calling a function on an object as the original question requested

I know this is an old question but I'm astonished that a rather obvious and disgusting hack isn't here.

You can exploit the ability to define your own ctor function to grab necessary values out of your services as you define them... obviously this would be ran every time the service was requested unless you explicitly remove/clear and re-add the definition of this service within the first construction of the exploiting ctor.

This method has the advantage of not requiring you to build the service tree, or use it, during the configuration of the service. You are still defining how services will be configured.

public void ConfigureServices(IServiceCollection services)
{
    //Prey this doesn't get GC'd or promote to a static class var
    string? somevalue = null;

    services.AddSingleton<IServiceINeedToUse, ServiceINeedToUse>(scope => {
         //create service you need
         var service = new ServiceINeedToUse(scope.GetService<IDependantService>())
         //get the values you need
         somevalue = somevalue ?? service.MyDirtyHack();
         //return the instance
         return service;
    });
    services.AddTransient<IOtherService, OtherService>(scope => {
         //Explicitly ensuring the ctor function above is called, and also showcasing why this is an anti-pattern.
         scope.GetService<IServiceINeedToUse>();
         //TODO: Clean up both the IServiceINeedToUse and IOtherService configuration here, then somehow rebuild the service tree.
         //Wow!
         return new OtherService(somevalue);
    });
}

The way to fix this pattern would be to give OtherService an explicit dependency on IServiceINeedToUse, rather than either implicitly depending on it or its method's return value... or resolving that dependency explicitly in some other fashion.

If Xcode complains when linking, e.g. Library not found for -lPods, it doesn't detect the implicit dependencies:

Go to Product > Edit Scheme Click on Build Add the Pods static library Clean and build again

Empty just check is the refered variable/array has an value if you check the php doc(empty) you'll see this things are considered emtpy

* "" (an empty string)
* 0 (0 as an integer)
* "0" (0 as a string)
* NULL
* FALSE
* array() (an empty array)
* var $var; (a variable declared, but without a value in a class)

while isset check if the variable isset and not null which can also be found in the php doc(isset)

  var popupWin = window.open('print.html', 'blank');
  popupWin.document.open();
  popupWin.document.write(''+ '<html>'+'<head>'+head+'</head>'+'<body onload="window.print()">' + '<div id="printable">' + printContents + '</div>'+'</body>'+'</html>');

You must convert to List as shown below:

    String[] valores = hierarquia.split(".");       
    List<String> lista =  Arrays.asList(valores);

    String jpqlQuery = "SELECT a " +
            "FROM AcessoScr a " +
            "WHERE a.scr IN :param ";

    Query query = getEntityManager().createQuery(jpqlQuery, AcessoScr.class);                   
    query.setParameter("param", lista);     
    List<AcessoScr> acessos = query.getResultList();

MySQL user defined variable (shared in session) could be used as logging output:

DELIMITER ;;
CREATE PROCEDURE Foo(tableName VARCHAR(128))
BEGIN
  SET @stmt = CONCAT('SELECT * FROM ', tableName);
  PREPARE pStmt FROM @stmt;
  EXECUTE pStmt;
  DEALLOCATE PREPARE pStmt;
  -- uncomment after debugging to cleanup
  -- SET @stmt = null;
END;;
DELIMITER ;

call Foo('foo');
select @stmt;

will output:

SELECT * FROM foo

To do the same I did following in terminal-

$ wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz
$ sudo tar -xzf postman.tar.gz -C /opt
$ rm postman.tar.gz
$ sudo ln -s /opt/Postman/Postman /usr/bin/postman

1. Now open file system, move to /usr/bin/ and search form "Postman"
2. There was a sh file with name 'Postman'
3. Double clicked on it which opened postman.
4. Locked icon to launcher on right clicking its icon for further use.

Hope will hell others too.

Even though this is a year old question, I would like to say that using dict will not help if you have an ordered dict within the ordered dict. The simplest way that could convert those recursive ordered dict will be

import json
from collections import OrderedDict
input_dict = OrderedDict([('method', 'constant'), ('recursive', OrderedDict([('m', 'c')]))])
output_dict = json.loads(json.dumps(input_dict))
print output_dict

your folder name is scripts..

and you are Referencing it like ../script/login.js

Also make sure that script folder is in your project directory

Thanks

A NullPointerException means that one of the variables you are passing is null, but the code tries to use it like it is not.

For example, If I do this:

Integer myInteger = null;
int n = myInteger.intValue();

The code tries to grab the intValue of myInteger, but since it is null, it does not have one: a null pointer exception happens.

What this means is that your getTask method is expecting something that is not a null, but you are passing a null. Figure out what getTask needs and pass what it wants!

Another important difference, that wasn't mentioned in any answer above, is that there is no equality operator for json type, but there is one for jsonb.

This means that you can't use DISTINCT keyword when selecting this json-type and/or other fields from a table (you can use DISTINCT ON instead, but it's not always possible because of cases like this).

If you are using Spring framework in your project you can also use:

org.springframework.util.StringUtils.parseLocaleString("en_US");

Documentation:

Parse the given String representation into a Locale

Here is an even shorter way of achieving this:

1) using Negative character class pattern matching

irb(main)> "((String1))"[/[^()]+/]
=> "String1"

^ - Matches anything NOT in the character class. Inside the charachter class, we have ( and )

Or with global substitution "AKA: gsub" like others have mentioned.

irb(main)> "((String1))".gsub(/[)(]/, '')
=> "String1"

Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.

Query below should help you achieve what you want.

select scountry, headofstate from data 
where data.scountry like 'a%'and ttlppl>=100000

Try it: sudo mysql_secure_installation

Work's in Ubuntu 18.04

Instead use use appendTo. append or appendTo returns a jQuery object so you don't have to wrap it inside $().

var holdyDiv = $('<div />').appendTo('body');
holdyDiv.attr('id', 'holdy');

.appendTo() reference: http://api.jquery.com/appendTo/

Alernatively you can try this also.

$('<div />', { id: 'holdy' }).appendTo('body');
               ^
             (Here you can specify any attribute/value pair you want)

I have seen this instead of the (void)param2 way of silencing the warning:

void foo(int param1, int param2)
{
    std::ignore = param2;
    bar(param1);
}

Looks like this was added in C++11

This is how Microsoft explains it:

.NET Framework is the "full" or "traditional" flavor of .NET that's distributed with Windows. Use this when you are building a desktop Windows or UWP app, or working with older ASP.NET 4.6+.

.NET Core is cross-platform .NET that runs on Windows, Mac, and Linux. Use this when you want to build console or web apps that can run on any platform, including inside Docker containers. This does not include UWP/desktop apps currently.

Xamarin is used for building mobile apps that can run on iOS, Android, or Windows Phone devices.

Xamarin usually runs on top of Mono, which is a version of .NET that was built for cross-platform support before Microsoft decided to officially go cross-platform with .NET Core. Like Xamarin, the Unity platform also runs on top of Mono.

A common point of confusion is where ASP.NET Core fits in. ASP.NET Core can run on top of either .NET Framework (Windows) or .NET Core (cross-platform), as detailed in this answer: Difference between ASP.NET Core (.NET Core) and ASP.NET Core (.NET Framework)

I just find out this ugly syntax could be "useful", or at least very fun to play with when you want to deal with an array of indexes which refer to positions into the same array. It can replace nested square brackets and make the code more readable !

int a[] = { 2 , 3 , 3 , 2 , 4 };
int s = sizeof a / sizeof *a;  //  s == 5

for(int i = 0 ; i < s ; ++i) {  
           
    cout << a[a[a[i]]] << endl;
    // ... is equivalent to ...
    cout << i[a][a][a] << endl;  // but I prefer this one, it's easier to increase the level of indirection (without loop)
    
}

Of course, I'm quite sure that there is no use case for that in real code, but I found it interesting anyway :)

you can install it using this command line

 echo @php "%~dp0composer.phar" %* > composer.bat

It's even possible to restore without creating a blank database at all.

In Sql Server Management Studio, right click on Databases and select Restore Database...

In the Restore Database dialog, select the Source Database or Device as normal. Once the source database is selected, SSMS will populate the destination database name based on the original name of the database.

It's then possible to change the name of the database and enter a new destination database name.

With this approach, you don't even need to go to the Options tab and click the "Overwrite the existing database" option.

Also, the database files will be named consistently with your new database name and you still have the option to change file names if you want.

To exec into a running container named test, below is the following commands

If the container has bash shell

docker exec -it test /bin/bash

If the container has bourne shell and most of the cases it's present

docker run -it test /bin/sh

try it out with the following code

function fun1()  
{  
   $this->db->select('count(DISTINCT(accessid))');  
   $this->db->from('accesslog');  
   $this->db->where('record =','123');  
   $query=$this->db->get();  
   return $query->num_rows();

In python the with keyword is used when working with unmanaged resources (like file streams). It is similar to the using statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally blocks.

From Python Docs:

The with statement clarifies code that previously would use try...finally blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.

The with statement is a control-flow structure whose basic structure is:

with expression [as variable]:
    with-block

The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has __enter__() and __exit__() methods).

Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with with using.

http: //localhost:8080/web

Where

• localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat.
• 8080 ( port ) is the address of the port on which the host server is listening for requests.

http ://localhost/web

Where

• localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat.
• host server listening to default port 80.

That's not the right way to set the permissions as you are overwriting them with each method call.

Replace this:

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

With the following, as the method setReadPermissions() accepts an ArrayList:

loginButton.setReadPermissions(Arrays.asList(
        "public_profile", "email", "user_birthday", "user_friends"));

Also here is how to query extra data GraphRequest:

private LoginButton loginButton;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (LoginButton) findViewById(R.id.login_button);

    loginButton.setReadPermissions(Arrays.asList(
            "public_profile", "email", "user_birthday", "user_friends"));

    callbackManager = CallbackManager.Factory.create();

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());

                            // Application code
                            String email = object.getString("email");
                            String birthday = object.getString("birthday"); // 01/31/1980 format
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday");
            request.setParameters(parameters);
            request.executeAsync();


        }

        @Override
        public void onCancel() {
            // App code
            Log.v("LoginActivity", "cancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });
}

EDIT:

One possible problem is that Facebook assumes that your email is invalid. To test it, use the Graph API Explorer and try to get it. If even there you can't get your email, change it in your profile settings and try again. This approach resolved this issue for some developers commenting my answer.

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);

This happened to me today after my Macbook's battery died. I think this can be caused by improper shutdown. All you have to do in cases such as mine is delete postmaster.pid

Navigate to the folder

cd /usr/local/var/postgres

Check to see if postmaster.pid is present

ls

Remove postmaster.pid

rm postmaster.pid

If you have configured jenkins on ec2 instance with linux AMI and looking to change the port. Edit the file at

sudo vi /etc/sysconfig/jenkins

Edit

JENKINS_PORT="your port number"

Exit vim

:wq

Restart jenkins

sudo service jenkins restart

Or simply start it, if its not already running

sudo service jenkins start

To verify if your jenkins is running on mentioned port

netstat -lntu | grep "your port number"

$(function () {
    $( ".droppable-area" ).sortable({
                connectWith: ".connected-sortable",
                containment: ".droppable-area", //(parent div)
                stack: '.connected-sortable div'
            }).disableSelection();
});

You need to restart the process if app.get not working. Press ctl+c and then restart node app.

Question : What is the best practice of returning/storing variables of multiple threads? A global hash table?

This totally depends on what you want to return and how you would use it? If you want to return only status of the thread (say whether the thread completed what it intended to do) then just use pthread_exit or use a return statement to return the value from the thread function.

But, if you want some more information which will be used for further processing then you can use global data structure. But, in that case you need to handle concurrency issues by using appropriate synchronization primitives. Or you can allocate some dynamic memory (preferrably for the structure in which you want to store the data) and send it via pthread_exit and once the thread joins, you update it in another global structure. In this way only the one main thread will update the global structure and concurrency issues are resolved. But, you need to make sure to free all the memory allocated by different threads.

dp4j has what you need. Essentially all you have to do is add dp4j to your classpath and whenever a method annotated with @Test (JUnit's annotation) calls a method that's private it will work (dp4j will inject the required reflection at compile-time). You may also use dp4j's @TestPrivates annotation to be more explicit.

If you insist on also annotating your private methods you may use Google's @VisibleForTesting annotation.

You can use anonymous class like this:

comboBox.DisplayMember = "Text";
comboBox.ValueMember = "Value";

comboBox.Items.Add(new { Text = "report A", Value = "reportA" });
comboBox.Items.Add(new { Text = "report B", Value = "reportB" });
comboBox.Items.Add(new { Text = "report C", Value = "reportC" });
comboBox.Items.Add(new { Text = "report D", Value = "reportD" });
comboBox.Items.Add(new { Text = "report E", Value = "reportE" });

UPDATE: Although above code will properly display in combo box, you will not be able to use SelectedValue or SelectedText properties of ComboBox. To be able to use those, bind combo box as below:

comboBox.DisplayMember = "Text";
comboBox.ValueMember = "Value";

var items = new[] { 
    new { Text = "report A", Value = "reportA" }, 
    new { Text = "report B", Value = "reportB" }, 
    new { Text = "report C", Value = "reportC" },
    new { Text = "report D", Value = "reportD" },
    new { Text = "report E", Value = "reportE" }
};

comboBox.DataSource = items;

Convert array to a string in PHP:

Use the PHP join function like this:

$my_array = array(4,1,8);

print_r($my_array);
Array
(
    [0] => 4
    [1] => 1
    [2] => 8
)

$result_string = join(',' , $my_array);
echo $result_string;

Which delimits the items in the array by comma into a string:

4,1,8

I would use a varchar(22). Big enough to hold a north american phone number with extension. You would want to strip out all the nasty '(', ')', '-' characters, or just parse them all into one uniform format.

I can suggest two options.

1. Within the method, assuming it is looping and not waiting for an external event, add a local field and test the time each time around the loop.

   void method() {
       long endTimeMillis = System.currentTimeMillis() + 10000;
       while (true) {
           // method logic
           if (System.currentTimeMillis() > endTimeMillis) {
               // do some clean-up
               return;
           }
       }
   }
   

2. Run the method in a thread, and have the caller count to 10 seconds.

   Thread thread = new Thread(new Runnable() {
           @Override
           public void run() {
               method();
           }
   });
   thread.start();
   long endTimeMillis = System.currentTimeMillis() + 10000;
   while (thread.isAlive()) {
       if (System.currentTimeMillis() > endTimeMillis) {
           // set an error flag
           break;
       }
       try {
           Thread.sleep(500);
       }
       catch (InterruptedException t) {}
   }
   

The drawback to this approach is that method() cannot return a value directly, it must update an instance field to return its value.

Maybe this old topic but i found this library is very helpful and easy to use

QRGen

example for using it in android

 Bitmap myBitmap = QRCode.from("www.example.org").bitmap();
ImageView myImage = (ImageView) findViewById(R.id.imageView);
myImage.setImageBitmap(myBitmap);

I know this is somewhat older, but since the keywords "border inside" landed me directly here, I would like to share some findings that may be worth mentioning here. When I was adding a border on the hover state, i got the effects that OP is talking about. The border ads pixels to the dimension of the box which made it jumpy. There is two more ways one can deal with this that also work for IE7.

1) Have a border already attached to the element and simply change the color. This way the mathematics are already included.

div {
   width:100px;
   height:100px;
   background-color: #aaa;
   border: 2px solid #aaa; /* notice the solid */
}

div:hover {
   border: 2px dashed #666;
}

2 ) Compensate your border with a negative margin. This will still add the extra pixels, but the positioning of the element will not be jumpy on

div {
   width:100px;
   height:100px;
   background-color: #aaa;
}

div:hover {
  margin: -2px;
  border: 2px dashed #333;
}

I adapted @mVchr's answer and inverted it to use for sticky ad positioning: if you need it absolutely positioned (scrolling) until the header junk is off screen but then need it to stay fixied/visible on screen after that:

$.fn.followTo = function (pos) {
    var stickyAd = $(this),
    theWindow = $(window);
    $(window).scroll(function (e) {
      if ($(window).scrollTop() > pos) {
        stickyAd.css({'position': 'fixed','top': '0'});
      } else {
        stickyAd.css({'position': 'absolute','top': pos});
      }
    });
  };
  $('#sticky-ad').followTo(740);

CSS:

#sticky-ad {
    float: left;
    display: block;
    position: absolute;
    top: 740px;
    left: -664px;
    margin-left: 50%;
    z-index: 9999;
}

If the file is native to your system (certainly no guarantees of that), then Node can help you out:

var os = require('os');

a.split(os.EOL);

This is usually more useful for constructing output strings from Node though, for platform portability.

A flow chart details the processes to follow. A DFD details the flow of data through a system.

In a flow chart, the arrows represent transfer of control (not data) between elements and the elements are instructions or decision (or I/O, etc).

In a DFD, the arrows are actually data transfer between the elements, which are themselves parts of a system.

Wikipedia has a good article on DFDs here.

For Windows.

In Android Studio:

Tools > Android > AVD Manager > Your Device > Pencil Icon> Show Advanced Settings > Memory and Storage > RAM > Set RAM to your preferred size.

In Control Panel:

Programs and Features > Intel Hardware Accelerated Execution Manager > Change > Set manually > Set RAM to your preferred size.

It is better for RAM sizes set in both places to be the same.

First of all, Thank you DTing for awesome answer. It's pretty much perfect.

For those who are suffering from not having GCC access in shared hosting, Go for ActivePython instead of normal python like Scott Stafford mentioned. Here are the commands for that.

wget http://downloads.activestate.com/ActivePython/releases/2.7.13.2713/ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz

tar -zxvf ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz

cd ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785

./install.sh

It will ask you path to python directory. Enter

../../.localpython

Just replace above as Step 1 in DTing's answer and go ahead with Step 2 after that. Please note that ActivePython package URL may change with new release. You can always get new URL from here : http://www.activestate.com/activepython/downloads

Based on URL you need to change the name of tar and cd command based on file received.

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

I would like to Add to NeilW's answer. To incorporate a method that resembles the orderby. Add this method as an extension:

public static void Sort<T>(this ObservableCollection<T> collection, Func<T,T> keySelector) where T : IComparable
{
    List<T> sorted = collection.OrderBy(keySelector).ToList();
    for (int i = 0; i < sorted.Count(); i++)
        collection.Move(collection.IndexOf(sorted[i]), i);
}

And use like:

myCollection = new ObservableCollection<MyObject>();

//Sorts in place, on a specific Func<T,T>
myCollection.Sort(x => x.ID);

A simple way is the NSSM Wrapper Wrapper (see my blog entry).

Another very basic free profiler: http://expressprofiler.codeplex.com

Parallel.ForEach will optimize(may not even start new threads) and block until the loop is finished, and Task.Factory will explicitly create a new task instance for each item, and return before they are finished (asynchronous tasks). Parallel.Foreach is much more efficient.

list comprehension? [x.strip() for x in lst]

Here is the formula

create a new rule in conditional formating based on a formula. Use the following formula and apply it to $A:$A

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

here is the example sheet to download if you encounter problems

UPDATE
here is @pnuts's suggestion which works perfect as well:

=MATCH(A1,B:B,0)>0

Simply use fs module and something like this:

fs.appendFile('server.log', 'string to append', function (err) {
   if (err) return console.log(err);
   console.log('Appended!');
});

In case your table does not have ths but only tds (with headers included) you can try the following which is based on Nick Grealy's answer above:

const getCellValue = (tr, idx) => tr.children[idx].innerText || tr.children[idx].textContent;_x000D_
_x000D_
const comparer = (idx, asc) => (a, b) => ((v1, v2) => _x000D_
    v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)_x000D_
    )(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));_x000D_
_x000D_
// do the work..._x000D_
document.querySelectorAll('tr:first-child td').forEach(td => td.addEventListener('click', (() => {_x000D_
    const table = td.closest('table');_x000D_
    Array.from(table.querySelectorAll('tr:nth-child(n+2)'))_x000D_
        .sort(comparer(Array.from(td.parentNode.children).indexOf(td), this.asc = !this.asc))_x000D_

I am in the same boat as you do. I need to study for tech interviews, but memorizing a list is not really helpful. If you have 3-4 hours to spare, and want to do a deeper dive, I recommend checking out

mycodeschool
I’ve looked on Coursera and other resources such as blogs and textbooks, but I find them either not comprehensive enough or at the other end of the spectrum, too dense with prerequisite computer science terminologies.

The dude in the video have a bunch of lectures on data structures. Don’t mind the silly drawings, or the slight accent at all. You need to understand not just which data structure to select, but some other points to consider when people think about data structures:

• pros and cons of the common data structures
• why each data structure exist
• how it actually work in the memory
• specific questions/exercises and deciding which structure to use for maximum efficiency
• lucid Big 0 explanation

I also posted notes on github if you are interested.

Use javascript

But it depends on what you are trying to do. If you just want to change the height and width, I suggest this:

{
document.getElementById('sample_id').style.height = '150px';
document.getElementById('sample_id').style.width = '150px';


}

TO totally remove it, remove the style, and then re-set the color:

getElementById('sample_id').removeAttribute("style");
document.getElementById('sample_id').style.color = 'red';

Of course, no the only question that remains is on which event you want this to happen.

It is very simple. I tried in SQL Server 2008

DELETE SUB FROM
(SELECT ROW_NUMBER() OVER (PARTITION BY EmpId, EmpName, EmpSSN ORDER BY EmpId) cnt
 FROM Employee) SUB
WHERE SUB.cnt > 1

The problem is that your REGX pattern will only match the input "0-9".

To meet your requirement (0-9999999), you should rewrite your regx pattern:

ng-pattern="/^[0-9]{1,7}$/"

My example:

HTML:

<div ng-app ng-controller="formCtrl">
  <form name="myForm" ng-submit="onSubmit()">
    <input type="number" ng-model="price" name="price_field" 
           ng-pattern="/^[0-9]{1,7}$/" required>
    <span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
    <span ng-show="myForm.price_field.$error.required">This field is required!</span>
    <input type="submit" value="submit"/>
  </form>
</div>

JS:

function formCtrl($scope){
  $scope.onSubmit = function(){
    alert("form submitted");
  }
}

Here is a jsFiddle demo.

Add android:dividerHeight="1px" and it will work:

<ListView
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/cashItemsList"
     android:cacheColorHint="#00000000"
     android:divider="@drawable/list_divider" android:dividerHeight="1px"></ListView>

If you only want to look at the memory usage of an object, (answer to other question)

There is a module called Pympler which contains the asizeof module.

Use as follows:

from pympler import asizeof
asizeof.asizeof(my_object)

Unlike sys.getsizeof, it works for your self-created objects.

>>> asizeof.asizeof(tuple('bcd'))
200
>>> asizeof.asizeof({'foo': 'bar', 'baz': 'bar'})
400
>>> asizeof.asizeof({})
280
>>> asizeof.asizeof({'foo':'bar'})
360
>>> asizeof.asizeof('foo')
40
>>> asizeof.asizeof(Bar())
352
>>> asizeof.asizeof(Bar().__dict__)
280

>>> help(asizeof.asizeof)
Help on function asizeof in module pympler.asizeof:

asizeof(*objs, **opts)
    Return the combined size in bytes of all objects passed as positional arguments.

print first converts the object to a string (if it is not already a string). It will also put a space before the object if it is not the start of a line and a newline character at the end.

When using stdout, you need to convert the object to a string yourself (by calling "str", for example) and there is no newline character.

So

print 99

is equivalent to:

import sys
sys.stdout.write(str(99) + '\n')

Passing,parsing arguments is an easy process. Node provides you with the process.argv property, which is an array of strings, which are the arguments that were used when Node was invoked. The first entry of the array is the Node executable, and the second entry is the name of your script.

If you run script with below atguments

$ node args.js arg1 arg2

File : args.js

console.log(process.argv)

You will get array like

 ['node','args.js','arg1','arg2']

Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).

$.each(json, function(arrayID,group) {
            console.log('<a href="'+group.GROUP_ID+'">');
    $.each(group.EVENTS, function(eventID,eventData) {
            console.log('<p>'+eventData.SHORT_DESC+'</p>');
     });
});

Should print out everything you were trying in your question.

http://jsfiddle.net/niklasvh/hZsQS/

edit renamed the variables to make it bit easier to understand what is what.

Can you provide an example, because put should work fine as well?

Documentation -

The type of request to make ("POST" or "GET"); the default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

Have the example in fiddle and the form parameters are passed fine (as it is put it will not be appended to url) -

$.ajax({
  url: '/echo/html/',
  type: 'PUT',
  data: "name=John&location=Boston",
  success: function(data) {
    alert('Load was performed.');
  }
});

You can retrieve information about the version of your JBoss EAP installation by running the same script used to start the server with the -V switch. For Linux and Unix installations this script is run.sh and on Microsoft Windows installations it is run.bat. Regardless of platform the script is located in $JBOSS_HOME/bin. Using these scripts to actually start your server is dealt with in Chapter 4, Launching the JBoss EAP Server.

select your table -> view dependencies -> Objects that depend on

The same solution can be written in a slightly different way as I would like to set the columns only once I have written about both the tables. Working in mysql.

SET t.col1 = o.col1, t.col2=o.col2
WHERE t.id = o.id

    button.contentVerticalAlignment=UIControlContentVerticalAlignmentFill;

java.time

The answer by MadProgrammer is correct, especially the tip about Joda-Time. The successor to Joda-Time is now built into Java 8 as the new java.time package. Here's example code in Java 8.

When working with date-time (as opposed to local date), the time zone in critical. The day-of-month depends on the time zone. For example, the India time zone is +05:30 (five and a half hours ahead of UTC), while France is only one hour ahead. So a moment in a new day in India has one date while the same moment in France has “yesterday’s” date. Creating string output lacking any time zone or offset information is creating ambiguity. You asked for YYYY-MM-DD output so I provided, but I don't recommend it. Instead of ISO_LOCAL_DATE I would have used ISO_DATE to get this output: 2014-02-25+05:30

ZoneId zoneId = ZoneId.of( "Asia/Kolkata" );
ZonedDateTime zonedDateTime = ZonedDateTime.now( zoneId );

DateTimeFormatter formatterOutput = DateTimeFormatter.ISO_LOCAL_DATE; // Caution: The "LOCAL" part means we are losing time zone information, creating ambiguity.
String output = formatterOutput.format( zonedDateTime );

Dump to console…

System.out.println( "zonedDateTime: " + zonedDateTime );
System.out.println( "output: " + output );

When run…

zonedDateTime: 2014-02-25T14:22:20.919+05:30[Asia/Kolkata]
output: 2014-02-25

Joda-Time

Similar code using the Joda-Time library, the precursor to java.time.

DateTimeZone zone = new DateTimeZone( "Asia/Kolkata" );
DateTime dateTime = DateTime.now( zone );
DateTimeFormatter formatter = ISODateTimeFormat.date();
String output = formatter.print( dateTime );

ISO 8601

By the way, that format of your input string is a standard format, one of several handy date-time string formats defined by ISO 8601.

Both Joda-Time and java.time use ISO 8601 formats by default when parsing and generating string representations of various date-time values.

You can have as many branches you want, just as a regular git repository, but according to heroku docs, any branch other than master will be ignored.

http://devcenter.heroku.com/articles/git

Branches pushed to Heroku other than master will be ignored. If you’re working out of another branch locally, you can either merge to master before pushing, or specify that you want to push your local branch to a remote master.

This means that you can push anything you want, but you app at heroku will always point to the master branch.

But, if you question regards how to create branches and to work with git you should check this other question

For 2020 Mac OS X Catalina users:

Forget about other useless answers, here only two steps needed:

1. Create a file with the naming convention: priority-appname. Then copy-paste the path you want to add to PATH.

   E.g. 80-vscode with content /Applications/Visual Studio Code.app/Contents/Resources/app/bin/ in my case.

2. Move that file to /etc/paths.d/. Don't forget to open a new tab(new session) in the Terminal and type echo $PATH to check that your path is added!

Notice: this method only appends your path to PATH.

Reviewing the basic terminology

It's usually good enough - unless you're programming assembly - to envisage a pointer containing a numeric memory address, with 1 referring to the second byte in the process's memory, 2 the third, 3 the fourth and so on....

• What happened to 0 and the first byte? Well, we'll get to that later - see null pointers below.
• For a more accurate definition of what pointers store, and how memory and addresses relate, see "More about memory addresses, and why you probably don't need to know" at the end of this answer.

When you want to access the data/value in the memory that the pointer points to - the contents of the address with that numerical index - then you dereference the pointer.

Different computer languages have different notations to tell the compiler or interpreter that you're now interested in the pointed-to object's (current) value - I focus below on C and C++.

A pointer scenario

Consider in C, given a pointer such as p below...

const char* p = "abc";

...four bytes with the numerical values used to encode the letters 'a', 'b', 'c', and a 0 byte to denote the end of the textual data, are stored somewhere in memory and the numerical address of that data is stored in p. This way C encodes text in memory is known as ASCIIZ.

For example, if the string literal happened to be at address 0x1000 and p a 32-bit pointer at 0x2000, the memory content would be:

Memory Address (hex)    Variable name    Contents
1000                                     'a' == 97 (ASCII)
1001                                     'b' == 98
1002                                     'c' == 99
1003                                     0
...
2000-2003               p                1000 hex

Note that there is no variable name/identifier for address 0x1000, but we can indirectly refer to the string literal using a pointer storing its address: p.

Dereferencing the pointer

To refer to the characters p points to, we dereference p using one of these notations (again, for C):

assert(*p == 'a');  // The first character at address p will be 'a'
assert(p[1] == 'b'); // p[1] actually dereferences a pointer created by adding
                     // p and 1 times the size of the things to which p points:
                     // In this case they're char which are 1 byte in C...
assert(*(p + 1) == 'b');  // Another notation for p[1]

You can also move pointers through the pointed-to data, dereferencing them as you go:

++p;  // Increment p so it's now 0x1001
assert(*p == 'b');  // p == 0x1001 which is where the 'b' is...

If you have some data that can be written to, then you can do things like this:

int x = 2;
int* p_x = &x;  // Put the address of the x variable into the pointer p_x
*p_x = 4;       // Change the memory at the address in p_x to be 4
assert(x == 4); // Check x is now 4

Above, you must have known at compile time that you would need a variable called x, and the code asks the compiler to arrange where it should be stored, ensuring the address will be available via &x.

Dereferencing and accessing a structure data member

In C, if you have a variable that is a pointer to a structure with data members, you can access those members using the -> dereferencing operator:

typedef struct X { int i_; double d_; } X;
X x;
X* p = &x;
p->d_ = 3.14159;  // Dereference and access data member x.d_
(*p).d_ *= -1;    // Another equivalent notation for accessing x.d_

Multi-byte data types

To use a pointer, a computer program also needs some insight into the type of data that is being pointed at - if that data type needs more than one byte to represent, then the pointer normally points to the lowest-numbered byte in the data.

So, looking at a slightly more complex example:

double sizes[] = { 10.3, 13.4, 11.2, 19.4 };
double* p = sizes;
assert(p[0] == 10.3);  // Knows to look at all the bytes in the first double value
assert(p[1] == 13.4);  // Actually looks at bytes from address p + 1 * sizeof(double)
                       // (sizeof(double) is almost always eight bytes)
++p;                   // Advance p by sizeof(double)
assert(*p == 13.4);    // The double at memory beginning at address p has value 13.4
*(p + 2) = 29.8;       // Change sizes[3] from 19.4 to 29.8
                       // Note earlier ++p and + 2 here => sizes[3]

Pointers to dynamically allocated memory

Sometimes you don't know how much memory you'll need until your program is running and sees what data is thrown at it... then you can dynamically allocate memory using malloc. It is common practice to store the address in a pointer...

int* p = (int*)malloc(sizeof(int)); // Get some memory somewhere...
*p = 10;            // Dereference the pointer to the memory, then write a value in
fn(*p);             // Call a function, passing it the value at address p
(*p) += 3;          // Change the value, adding 3 to it
free(p);            // Release the memory back to the heap allocation library

In C++, memory allocation is normally done with the new operator, and deallocation with delete:

int* p = new int(10); // Memory for one int with initial value 10
delete p;

p = new int[10];      // Memory for ten ints with unspecified initial value
delete[] p;

p = new int[10]();    // Memory for ten ints that are value initialised (to 0)
delete[] p;

See also C++ smart pointers below.

Losing and leaking addresses

Often a pointer may be the only indication of where some data or buffer exists in memory. If ongoing use of that data/buffer is needed, or the ability to call free() or delete to avoid leaking the memory, then the programmer must operate on a copy of the pointer...

const char* p = asprintf("name: %s", name);  // Common but non-Standard printf-on-heap

// Replace non-printable characters with underscores....
for (const char* q = p; *q; ++q)
    if (!isprint(*q))
        *q = '_';

printf("%s\n", p); // Only q was modified
free(p);

...or carefully orchestrate reversal of any changes...

const size_t n = ...;
p += n;
...
p -= n;  // Restore earlier value...
free(p);

C++ smart pointers

In C++, it's best practice to use smart pointer objects to store and manage the pointers, automatically deallocating them when the smart pointers' destructors run. Since C++11 the Standard Library provides two, unique_ptr for when there's a single owner for an allocated object...

{
    std::unique_ptr<T> p{new T(42, "meaning")};
    call_a_function(p);
    // The function above might throw, so delete here is unreliable, but...
} // p's destructor's guaranteed to run "here", calling delete

...and shared_ptr for share ownership (using reference counting)...

{
    auto p = std::make_shared<T>(3.14, "pi");
    number_storage1.may_add(p); // Might copy p into its container
    number_storage2.may_add(p); // Might copy p into its container    } // p's destructor will only delete the T if neither may_add copied it

Null pointers

In C, NULL and 0 - and additionally in C++ nullptr - can be used to indicate that a pointer doesn't currently hold the memory address of a variable, and shouldn't be dereferenced or used in pointer arithmetic. For example:

const char* p_filename = NULL; // Or "= 0", or "= nullptr" in C++
int c;
while ((c = getopt(argc, argv, "f:")) != -1)
    switch (c) {
      case f: p_filename = optarg; break;
    }
if (p_filename)  // Only NULL converts to false
    ...   // Only get here if -f flag specified

In C and C++, just as inbuilt numeric types don't necessarily default to 0, nor bools to false, pointers are not always set to NULL. All these are set to 0/false/NULL when they're static variables or (C++ only) direct or indirect member variables of static objects or their bases, or undergo zero initialisation (e.g. new T(); and new T(x, y, z); perform zero-initialisation on T's members including pointers, whereas new T; does not).

Further, when you assign 0, NULL and nullptr to a pointer the bits in the pointer are not necessarily all reset: the pointer may not contain "0" at the hardware level, or refer to address 0 in your virtual address space. The compiler is allowed to store something else there if it has reason to, but whatever it does - if you come along and compare the pointer to 0, NULL, nullptr or another pointer that was assigned any of those, the comparison must work as expected. So, below the source code at the compiler level, "NULL" is potentially a bit "magical" in the C and C++ languages...

More about memory addresses, and why you probably don't need to know

More strictly, initialised pointers store a bit-pattern identifying either NULL or a (often virtual) memory address.

The simple case is where this is a numeric offset into the process's entire virtual address space; in more complex cases the pointer may be relative to some specific memory area, which the CPU may select based on CPU "segment" registers or some manner of segment id encoded in the bit-pattern, and/or looking in different places depending on the machine code instructions using the address.

For example, an int* properly initialised to point to an int variable might - after casting to a float* - access memory in "GPU" memory quite distinct from the memory where the int variable is, then once cast to and used as a function pointer it might point into further distinct memory holding machine opcodes for the program (with the numeric value of the int* effectively a random, invalid pointer within these other memory regions).

3GL programming languages like C and C++ tend to hide this complexity, such that:

• If the compiler gives you a pointer to a variable or function, you can dereference it freely (as long as the variable's not destructed/deallocated meanwhile) and it's the compiler's problem whether e.g. a particular CPU segment register needs to be restored beforehand, or a distinct machine code instruction used

• If you get a pointer to an element in an array, you can use pointer arithmetic to move anywhere else in the array, or even to form an address one-past-the-end of the array that's legal to compare with other pointers to elements in the array (or that have similarly been moved by pointer arithmetic to the same one-past-the-end value); again in C and C++, it's up to the compiler to ensure this "just works"

• Specific OS functions, e.g. shared memory mapping, may give you pointers, and they'll "just work" within the range of addresses that makes sense for them

• Attempts to move legal pointers beyond these boundaries, or to cast arbitrary numbers to pointers, or use pointers cast to unrelated types, typically have undefined behaviour, so should be avoided in higher level libraries and applications, but code for OSes, device drivers, etc. may need to rely on behaviour left undefined by the C or C++ Standard, that is nevertheless well defined by their specific implementation or hardware.

I have edited @Ivan's answer to display "No Preview Available" image, if it is not an image:

function readURL(input) {
    var url = input.value;
    var ext = url.substring(url.lastIndexOf('.') + 1).toLowerCase();
    if (input.files && input.files[0]&& (ext == "gif" || ext == "png" || ext == "jpeg" || ext == "jpg")) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('.imagepreview').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }else{
         $('.imagepreview').attr('src', '/assets/no_preview.png');
    }
}

You can use this:

list=$(find /home/user/Desktop -name '*.pdf' -o -name '*.txt' -o -name '*.bmp')

Besides, you might want to use -iname instead of -name to catch files with ".PDF" (upper-case) extension as well.

$('#someid').attr('disabled', 'true');

Based on what I read from different sources:

An await expression does not block the thread on which it is executing. Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. Control then returns to the caller of the async method. When the task completes, it invokes its continuation, and execution of the async method resumes where it left off.

To wait for a single task to complete, you can call its Task.Wait method. A call to the Wait method blocks the calling thread until the single class instance has completed execution. The parameterless Wait() method is used to wait unconditionally until a task completes. The task simulates work by calling the Thread.Sleep method to sleep for two seconds.

This article is also a good read.

I recommend using Prettier as it's very extensible but still works perfectly out of the box:

1. CMD + Shift + P -> Format Document

or

1. Select the text you want to Prettify
2. CMD + Shift + P -> Format Selection

I use an immediately invoked lambda for these scenarios:

const config = (() => {
  try {
    return JSON.parse(fs.readFileSync('config.json'));
  } catch (error) {
    return {};
  }
})();

async version:

const config = await (async () => {
  try {
    return JSON.parse(await fs.readFileAsync('config.json'));
  } catch (error) {
    return {};
  }
})();

New in Python 3.9: Use the union operator (|) to merge dicts similar to sets:

>>> d = {'a': 1, 'b': 2}
>>> e = {'a': 9, 'c': 3}
>>> d | e
{'a': 9, 'b': 2, 'c': 3}

For matching keys, the right dict takes precedence.

This also works for |= to modify a dict in-place:

>>> e |= d    # e = e | d
>>> e
{'a': 1, 'c': 3, 'b': 2}

[x for x in L if 'ab' in x]

If you trying to fit the content according to the forms than the following will help. It helps me while I was trying to fit the content on the form to fit when ever the forms were resized.

this.contents.Size = new Size(this.ClientRectangle.Width, this.ClientRectangle.Height);

I'm not sure if that is possible. The MSDN GetFiles reference says a search pattern, not a list of search patterns.

I might be inclined to fetch each list separately and "foreach" them into a final list.

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20

I wanted to have two separate instances of Chrome running, each using its own profile. I wanted to be able to start them from Spotlight, as is my habit for starting Mac apps. In other words, I needed two regular Mac applications, regChrome for normal browsing and altChrome to use the special profile, to be easily started by keying ?-space to bring up Spotlight, then 'reg' or 'alt', then Enter.

I suppose the brute-force way to accomplish the above goal would be to make two copies of the Google Chrome application bundle under the respective names. But that's ugly and complicates updating.

What I ended up with was two AppleScript applications containing two commands each. Here is the one for altChrome:

do shell script "cd /Applications/Google\\ Chrome.app/Contents/Resources/; rm app.icns; ln /Users/garbuck/local/chromeLaunchers/Chrome-swirl.icns app.icns"
do shell script "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome --user-data-dir=/Users/garbuck/altChrome >/dev/null 2>&1 &"

The second line starts Chrome with the alternate profile (the --user-data-dir parameter).

The first line is an unsuccessful attempt to give the two applications distinct icons. Initially, it appears to work fine. However, sooner or later, Chrome rereads its icon file and gets the one corresponding to whichever of the two apps was started last, resulting in two running applications with the same icon. But I haven't bothered to try to fix it — I keep the two browsers on separate desktops, and navigating between them hasn't been a problem.

For swift 2.0:

let cacheSizeMemory = 4*1024*1024; // 4MB
let cacheSizeDisk = 32*1024*1024; // 32MB
let sharedCache = NSURLCache(memoryCapacity: cacheSizeMemory, diskCapacity: cacheSizeDisk, diskPath: "nsurlcache")
NSURLCache.setSharedURLCache(sharedCache)

Try Firefox with Firebug addons installed. I'm using it; great tool for web developer.

This is a complete working Console solution based on the example provided in here:

class Program
{
    static string[] words1 = new string[] { "brown", "jumped", "the", "fox", "quick" };

    static void Main()
    {
        var result = Shuffle(words1);
        foreach (var i in result)
        {
            Console.Write(i + " ");
        }
        Console.ReadKey();
    }

   static string[] Shuffle(string[] wordArray) {
        Random random = new Random();
        for (int i = wordArray.Length - 1; i > 0; i--)
        {
            int swapIndex = random.Next(i + 1);
            string temp = wordArray[i];
            wordArray[i] = wordArray[swapIndex];
            wordArray[swapIndex] = temp;
        }
        return wordArray;
    }         
}

Install "angular-2-local-storage"

import { LocalStorageService } from 'angular-2-local-storage';

String extends Object, which means an Object. Object o = a; If you really want to get as Object, you may do like below.

String s = "Hi";

Object a =s;

To use the push function of an Array your var needs to be an Array.

Change data{"name":"ananta","age":"15"} to following:

var data = [
    { 
        "name": "ananta",
        "age": "15",
        "country": "Atlanta"
    }
];

data.push({"name": "Tony Montana", "age": "99"});

data.push({"country": "IN"});

..

The containing Array Items will be typeof Object and you can do following:

var text = "You are " + data[0]->age + " old and come from " + data[0]->country;

Notice: Try to be consistent. In my example, one array contained object properties name and age while the other only contains country. If I iterate this with for or forEach then I can't always check for one property, because my example contains Items that changing.

Perfect would be: data.push({ "name": "Max", "age": "5", "country": "Anywhere" } );

So you can iterate and always can get the properties, even if they are empty, null or undefined.

edit

Cool stuff to know:

var array = new Array();

is similar to:

var array = [];

Also:

var object = new Object();

is similar to:

var object = {};

You also can combine them:

var objectArray = [{}, {}, {}];

Format in scientific notation and pluck off the exponent:

int("{:.5e}".format(1000000).split("e")[1]) + 1

I don't know about speed, but it's simple.

Please note the number of significant digits after the decimal (the "5" in the ".5e" can be an issue if it rounds up the decimal part of the scientific notation to another digit. I set it arbitrarily large, but could reflect the length of the largest number you know about.

First of all if the size of the image is smaller than the container, then only "img-fluid" class will not solve your problem. you have to set the width of image to 100%, for that you can use Bootstrap class "w-100". keep in mind that "container-fluid" and "col-12" class sets left and right padding to 15px and "row" class sets left and right margin to "-15px" by default. make sure to set them to 0.

Note: "px-0" is a bootstrap class which sets left and right padding to 0 and
"mx-0" is a bootstrap class which sets left and right margin to 0

P.S. i am using Bootstrap 4.0 version.

 <div class="container-fluid px-0">
        <div class="row mx-0">
            <div class="col-12 px-0">
            <img src="images/top.jpg" class="img-fluid w-100">
            </div>
        </div>
    </div>

Or you can use in code whatever you might think of in PSD:

    private void FillCustomGradient(View v) {
        final View view = v;
        Drawable[] layers = new Drawable[1];

        ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
            @Override
            public Shader resize(int width, int height) {
                LinearGradient lg = new LinearGradient(
                        0,
                        0,
                        0,
                        view.getHeight(),
                        new int[] {
                                 getResources().getColor(R.color.color1), // please input your color from resource for color-4
                                 getResources().getColor(R.color.color2),
                                 getResources().getColor(R.color.color3),
                                 getResources().getColor(R.color.color4)},
                        new float[] { 0, 0.49f, 0.50f, 1 },
                        Shader.TileMode.CLAMP);
                return lg;
            }
        };
        PaintDrawable p = new PaintDrawable();
        p.setShape(new RectShape());
        p.setShaderFactory(sf);
        p.setCornerRadii(new float[] { 5, 5, 5, 5, 0, 0, 0, 0 });
        layers[0] = (Drawable) p;

        LayerDrawable composite = new LayerDrawable(layers);
        view.setBackgroundDrawable(composite);
    }

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

In general it's a pain to write a regular expression not containing a particular string. We had to do this for models of computation - you take an NFA, which is easy enough to define, and then reduce it to a regular expression. The expression for things not containing "cat" was about 80 characters long.

Edit: I just finished and yes, it's:

aa([^a] | a[^a])aa

Here is a very brief tutorial. I found some great ones before, but I can't see them anymore.

A double primitive in Java can never be null. It will be initialized to 0.0 if no value has been given for it (except when declaring a local double variable and not assigning a value, but this will produce a compile-time error).

More info on default primitive values here.

My guess is a wrong version of project A jar in your local maven repository. It seems that the dependency is resolved otherwise I think maven does not start compiling but usually these compiling error means that you have a version mix up. try to make a maven clean install of your project A and see if it changes something for the project B... Also a little more information on your setting could be useful:

• How is maven launched? what command? on a shell, an IDE (using a plugin or not), on a CI server?
• What maven command are you using?

Replace this:

var cat = $.jqURL.get('category');
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
    $(this).select(); // This is where my problem is
});

With this:

$('#cbCategory').val(cat);

Calling val() on a select list will automatically select the option with that value, if any.

Well, you can use the CASE statement:

SELECT
    CASE
        WHEN Date1 >= Date2 AND Date1 >= Date3 THEN Date1
        WHEN Date2 >= Date1 AND Date2 >= Date3 THEN Date2
        WHEN Date3 >= Date1 AND Date3 >= Date2 THEN Date3
        ELSE                                        Date1
    END AS MostRecentDate

[For Microsoft SQL Server 2008 and above, you may consider Sven's simpler answer below.]

Every SQL statement executed by the Oracle database has a cursor associated with it, which is a private work area to store processing information. Implicit cursors are implicitly created by the Oracle server for all DML and SELECT statements.

You can declare and use Explicit cursors to name the private work area, and access its stored information in your program block.

If you're removing a commit and don't want to keep its changes @ferit has a good solution.

If you want to add that commit to the current branch, but doesn't make sense to be part of the current pr, you can do the following instead:

1. use git rebase -i HEAD~n
2. Swap the commit you want to remove to the bottom (most recent) position
3. Save and exit
4. use git reset HEAD^ --soft to uncommit the changes and get them back in a staged state.
5. use git push --force to update the remote branch without your removed commit.

Now you'll have removed the commit from your remote, but will still have the changes locally.

Without Virtual Environments

pip <command> --user changes the scope of the current pip command to work on the current user account's local python package install location, rather than the system-wide package install location, which is the default.

• See User Installs in the PIP User Guide.

This only really matters on a multi-user machine. Anything installed to the system location will be visible to all users, so installing to the user location will keep that package installation separate from other users (they will not see it, and would have to install it themselves separately to use it). Because there can be version conflicts, installing a package with dependencies needed by other packages can cause problems, so it's best not to push all packages a given user uses to the system install location.

• If it is a single-user machine, there is little or no difference to installing to the --user location. It will be installed to a different folder, that may or may not need to be added to the path, depending on the package and how it's used (many packages install command-line tools that must be on the path to run from a shell).
• If it is a multi-user machine, --user is preferred to using root/sudo or requiring administrator installation and affecting the Python environment of every user, except in cases of general packages that the administrator wants to make available to all users by default.
  • Note: Per comments, on most Unix/Linux installs it has been pointed out that system installs should use the general package manager, such as apt, rather than pip.

With Virtual Environments

• See more about installing packages with virtual environments in the Python Packaging documentation.
• Read about how to create and use virtual environments, and the venv command in the Python VENV docs.

The --user option in an active venv/virtualenv environment will install to the local user python location (same as without a virtual environment).

Packages are installed to the virtual environment by default, but if you use --user it will force it to install outside the virtual environments, in the users python script directory (in Windows, this currently is c:\users\<username>\appdata\roaming\python\python37\scripts for me with Python 3.7).

However, you won't be able to access a system or user install from within virtual environment (even if you used --user while in a virtual environment).

If you install a virtual environment with the --system-site-packages argument, you will have access to the system script folder for python. I believe this included the user python script folder as well, but I'm unsure. However, there may be unintended consequences for this and it is not the intended way to use virtual environments.

Location of the Python System and Local User Install Folders

You can find the location of the user install folder for python with python -m site --user-base. I'm finding conflicting information in Q&A's, the documentation and actually using this command on my PC as to what the defaults are, but they are underneath the user home directory (~ shortcut in *nix, and c:\users\<username> typically for Windows).

Other Details

The --user option is not a valid for every command. For example pip uninstall will find and uninstall packages wherever they were installed (in the user folder, virtual environment folder, etc.) and the --user option is not valid.

Things installed with pip install --user will be installed in a local location that will only be seen by the current user account, and will not require root access (on *nix) or administrator access (on Windows).

The --user option modifies all pip commands that accept it to see/operate on the user install folder, so if you use pip list --user it will only show you packages installed with pip install --user.

What about the SystemParameters class in PresentationFramework? It has a WorkArea property that seems to be what you are looking for.

But, why won't setting the Window.WindowStartupLocation work? CenterScreen is one of the enum values. Do you have to tweak the centering?

Use something like the following on the server side:

http.createServer(function (request, response) {
    if (request.headers['x-requested-with'] == 'XMLHttpRequest') {
        // handle async request
        var u = url.parse(request.url, true); //not needed

        response.writeHead(200, {'content-type':'text/json'})
        response.end(JSON.stringify(some_array.slice(1, 10))) //send elements 1 to 10
    } else {
        // handle sync request (by server index.html)
        if (request.url == '/') {
            response.writeHead(200, {'content-type': 'text/html'})
            util.pump(fs.createReadStream('index.html'), response)
        } 
        else 
        {
            // 404 error
        }
    }
}).listen(31337)

$str = trim(preg_replace('/\s+/',' ', $str));

The above line of code will remove extra spaces, as well as leading and trailing spaces.

::: works only with lists, while ++ can be used with any traversable. In the current implementation (2.9.0), ++ falls back on ::: if the argument is also a List.

This blog post explains it perfectly: Ruby's Exception vs StandardError: What's the difference?

Why you shouldn't rescue Exception

The problem with rescuing Exception is that it actually rescues every exception that inherits from Exception. Which is....all of them!

That's a problem because there are some exceptions that are used internally by Ruby. They don't have anything to do with your app, and swallowing them will cause bad things to happen.

Here are a few of the big ones:

• SignalException::Interrupt - If you rescue this, you can't exit your app by hitting control-c.

• ScriptError::SyntaxError - Swallowing syntax errors means that things like puts("Forgot something) will fail silently.

• NoMemoryError - Wanna know what happens when your program keeps running after it uses up all the RAM? Me neither.

begin
  do_something()
rescue Exception => e
  # Don't do this. This will swallow every single exception. Nothing gets past it. 
end

I'm guessing that you don't really want to swallow any of these system-level exceptions. You only want to catch all of your application level errors. The exceptions caused YOUR code.

Luckily, there's an easy way to to this.

Rescue StandardError Instead

All of the exceptions that you should care about inherit from StandardError. These are our old friends:

NoMethodError - raised when you try to invoke a method that doesn't exist

TypeError - caused by things like 1 + ""

RuntimeError - who could forget good old RuntimeError?

To rescue errors like these, you'll want to rescue StandardError. You COULD do it by writing something like this:

begin
  do_something()
rescue StandardError => e
  # Only your app's exceptions are swallowed. Things like SyntaxErrror are left alone. 
end

But Ruby has made it much easier for use.

When you don't specify an exception class at all, ruby assumes you mean StandardError. So the code below is identical to the above code:

begin
  do_something()
rescue => e
  # This is the same as rescuing StandardError
end

PDFJet offers an open-source version of their library that should be able to handle any basic PDF generation task. It's a purely Java-based solution and it is stated to be compatible with Android. There is a commercial version with some additional features that does not appear to be too expensive.

I worked around this exact error by not adding the ListBox to a parent Page/Control Controls collection. Because I really didn't need any server-side functionality out of it. I just wanted to use it to output the HTML for a custom server control, which I did in the OnRender event handler myself. I hoped that using the control would save me from writing to the response my own html.

This solution probably won't work for most, but it keeps ASP.NET from performing the ValidateEvent against the control, because the control doesn't retain in memory between postbacks.

Also, my error was specifically caused by the selected list item being an item that wasn't in the listbox the previous postback. Incase that helps anyone.

This is a tough problem and you will need to find out this information using static analysis, its not available easily at runtime. Basically get the classpath of your app and scan through the available classes and read the bytecode information of a class which class it inherits from. Note that a class Dog may not directly inherit from Animal but might inherit from Pet which is turn inherits from Animal,so you will need to keep track of that hierarchy.

If you face this erorr connecting from remote, go to remote mysql option in cpanel and then add % in Host (% wildcard is allowed) .

a=(e b 'c d')
shuf -e "${a[@]}" | sort >/tmp/f
mapfile -t g </tmp/f

One way is:

Write-Host "$($assoc.Id)  -  $($assoc.Name)  -  $($assoc.Owner)"

Another one is:

Write-Host  ("{0}  -  {1}  -  {2}" -f $assoc.Id,$assoc.Name,$assoc.Owner )

Or just (but I don't like it ;) ):

Write-Host $assoc.Id  "  -  "   $assoc.Name  "  -  "  $assoc.Owner

You can do it like this:

uint8_t (*matrix_ptr)[10][20] = &l_matrix;

Use the hashchange event:

window.addEventListener("hashchange", function(e) {
  // ...
})

If you need to support older browsers, check out the hashChange Event section in Modernizr's HTML5 Cross Browser Polyfills wiki page.

If you are running in a local server, such as wamp or xampp, make sure it's using the php.ini you think it is. These servers usually default to a php.ini that's not in your html docs folder.

Make it serializable

// example error
let err = new Error('I errored')

// one liner converting Error into regular object that can be stringified
err = Object.getOwnPropertyNames(err).reduce((acc, key) => { acc[key] = err[key]; return acc; }, {})

If you want to send this object from child process, worker or though the network there's no need to stringify. It will be automatically stringified and parsed like any other normal object

What helped me with that error was Juan's answer - https://stackoverflow.com/a/20204635/4433222 But wasn't enough - after struggling I found out that an XML file needs to be saved with UTF-8 without BOM encoding.

The solution wasn't working for "normal" UTF-8.

Follow the steps:-

1. 1] sqlite3 name 2] .mode csv tablename 3] .import Filename.csv tablename

<select class="design" id="sel" name="subject">
   <option value="0">- Please Select -</option>
   <option value="1"> Example1 </option>
   <option value="2"> Example2 </option>
   <option value="3"> Example3 </option>
   <option value="4"> Example4 </option>
</select>
<label class="error" id="select_error" style="color:#FC2727">
   <b> Warning : You have to Select One Item.</b>
</label>
<input type="submit" name="sub" value="Gönder" class="">

JQuery :

jQuery(function() {  
    jQuery('.error').hide(); // Hide Warning Label. 
    jQuery("input[name=sub]").on("click", function() {
        var returnvalue;
        if(jQuery("select[name=subject]").val() == 0) {
            jQuery("label#select_error").show(); // show Warning 
            jQuery("select#sel").focus();  // Focus the select box      
            returnvalue=false;   
        }
        return returnvalue;
    });
});  // you can change jQuery with $

There are several ways to get a string length:

package main

import (
    "bytes"
    "fmt"
    "strings"
    "unicode/utf8"
)

func main() {
    b := "?????"
    len1 := len([]rune(b))
    len2 := bytes.Count([]byte(b), nil) -1
    len3 := strings.Count(b, "") - 1
    len4 := utf8.RuneCountInString(b)
    fmt.Println(len1)
    fmt.Println(len2)
    fmt.Println(len3)
    fmt.Println(len4)

}

Do you need the list to be sorted in place, or just an ordered sequence of the contents of the list? The latter is easier:

var peopleInOrder = people.OrderBy(person => person.LastName);

To sort in place, you'd need an IComparer<Person> or a Comparison<Person>. For that, you may wish to consider ProjectionComparer in MiscUtil.

(I know I keep bringing MiscUtil up - it just keeps being relevant...)

I'f you're suppsed to be able to use it, then 3rd-party library should have a *.lib file as well as a *.dll file. You simply need to add the *.lib to the list of input file in your project's 'Linker' options.

This *.lib file isn't necessarily a 'static' library (which contains code): instead a *.lib can be just a file that links your executable to the DLL.

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

I found the reference in boot.ts wasn't the correct path. Updating that path to /// <reference path=">../../../node_modules/angular2/typings/browser.d.ts" /> resolved the Promise errors.

I strongly recommend the MahApps it's simply awesome!

The Groovy script you provided is formatting the first line as a blank line in the resultant script. The shebang, telling the script to run with /bin/bash instead of /bin/sh, needs to be on the first line of the file or it will be ignored.

So instead, you should format your Groovy like this:

stage('Setting the variables values') {
    steps {
         sh '''#!/bin/bash
                 echo "hello world" 
         '''
    }
}

And it will execute with /bin/bash.

In my case, I ran into this error this way. pom.xml of my project defined two dependencies A and B. And both A and B defined dependency on same artifact (call it C) but different versions of it (C.1 and C.2). When this happens, for each class in C maven can only select one version of the class from the two versions (while building an uber-jar). It will select the "nearest" version based on its dependency mediation rules and will output a warning "We have a duplicate class..." If a method/class signature changes between the versions, it can cause a java.lang.IncompatibleClassChangeError exception if the incorrect version is used at runtime.

Advanced: If A must use v1 of C and B must use v2 of C, then we must relocate C in A and B's poms to avoid class conflict (we have a duplicate class warning) when building the final project that depends on both A and B.

The most popular option is to use some third party library distributed as npm package like ng2-bootstrap project https://github.com/valor-software/ng2-bootstrap or Angular UI Bootstrap library.

I personally use ng2-bootstrap. There are many ways to configure it, because configuration depends on how your Angular project is build. Underneath I post example configuration based on Angular 2 QuickStart project https://github.com/angular/quickstart

Firstly we add dependencies in our package.json

    { ...
"dependencies": {
    "@angular/common": "~2.4.0",
    "@angular/compiler": "~2.4.0",
    "@angular/core": "~2.4.0",

    ...

    "bootstrap": "^3.3.7",
    "ng2-bootstrap": "1.1.16-11"
  },
... }

Then we have to map names to proper URL's in systemjs.config.js

(function (global) {
  System.config({
    ...
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',

      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

      //bootstrap
      'moment': 'npm:moment/bundles/moment.umd.js',
      'ng2-bootstrap': 'npm:ng2-bootstrap/bundles/ng2-bootstrap.umd.js',

      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
    },
...
  });
})(this);

We have to import bootstrap .css file in index.html. We can get it from /node_modules/bootstrap directory on our hard drive (because we added bootstrap 3.3.7 dependency) or from web. There we are obtaining it from web:

<!DOCTYPE html>
<html>
  <head>
    ...
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    ...
  </head>

  <body>
    <my-app>Loading...</my-app>
  </body>
</html>

We should edit our app.module.ts file from /app directory

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

//bootstrap alert import part 1
import {AlertModule} from 'ng2-bootstrap';

import { AppComponent }  from './app.component';


@NgModule({
  //bootstrap alert import part 2
  imports:      [ BrowserModule, AlertModule.forRoot() ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

And finally our app.component.ts file from /app directory

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: `
    <alert type="success">
        Well done!
    </alert>
    `
})

export class AppComponent {

    constructor() { }

}

Then we have to install our bootstrap and ng2-bootstrap dependencies before we run our app. We should go to our project directory and type

npm install

Finally we can start our app

npm start

There are many code samples on ng2-bootstrap project github showing how to import ng2-bootstrap to various Angular 2 project builds. There is even plnkr sample. There is also API documentation on Valor-software (authors of the library) website.

The idea is to send a callback to the child which will be called to give the data back

A complete and minimal example using functions:

App will create a Child which will compute a random number and send it back directly to the parent, which will console.log the result

const Child = ({ handleRandom }) => {
  handleRandom(Math.random())

  return <span>child</span>
}

const App = () => <Child handleRandom={(num) => console.log(num)}/>

Just use xcopy /y source destination

Use atof()

But this is deprecated, use this instead:

const char* flt = "4.0800";
float f;
sscanf(flt, "%f", &f);

http://www.cplusplus.com/reference/clibrary/cstdlib/atof/

atof() returns 0 for both failure and on conversion of 0.0, best to not use it.

I got this error when trying to create a new Eclipse project inside a newly cloned Git repo folder.

This worked for me:

1) clone the Git repo (in my case it was to a subfolder of the Eclipse default workspace)

2) create the new Eclipse project in the default workspace (one level above the cloned Git repo folder)

3) export the new Eclipse project from the default workspace to the cloned repo directory:

a) right click on project --> Export --> General --> File System
b) select the new Eclipse project
c) set the destination directory to export to (as the Git repo folder)

4) remove the Eclipse project form the workspace (because it's still the one that uses the default workspace)

right click on project and select "Delete"

5) open the exported Eclipse project from inside the Git repo directory

a) File --> Open Project from File System or Archive
b) set the "Import source" folder as the Git repo folder
c) check the project to import (that you just exported there)

If you don't want to block the current thread by waiting/checking for the other running thread completion, you can implement callback method like this.

Action onCompleted = () => 
{  
    //On complete action
};

var thread = new Thread(
  () =>
  {
    try
    {
      // Do your work
    }
    finally
    {
      onCompleted();
    }
  });
thread.Start();

If you are dealing with controls that doesn't support cross-thread operation, then you have to invoke the callback method

this.Invoke(onCompleted);

I am not exactly sure which part to blame, but here's why MemoryStream doesn't work for you:

As you write to MemoryStream, it increments it's Position property. The constructor of StreamContent takes into account the stream's current Position. So if you write to the stream, then pass it to StreamContent, the response will start from the nothingness at the end of the stream.

There's two ways to properly fix this:

1) construct content, write to stream

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    // ...
    // stream.Write(...);
    // ...
    return response;
}

2) write to stream, reset position, construct content

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    // ...
    // stream.Write(...);
    // ...
    stream.Position = 0;

    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    return response;
}

2) looks a little better if you have a fresh Stream, 1) is simpler if your stream does not start at 0

I'll add a map and filter version because why not.

sum(map(lambda x:x>5, j))
sum(1 for _ in filter(lambda x:x>5, j))

While in insert mode hit CTRL-R {register}

Examples:

• CTRL-R * will insert in the contents of the clipboard
• CTRL-R " (the unnamed register) inserts the last delete or yank.

To find this in vim's help type :h i_ctrl-r

In this case, there are two videos because the live stream contains two cameras. From here, we need to get the HLS URL for a specific stream. Use -f to pass in the format you would like to watch, and -g to get that stream's URL:

These are your HLS m3u8 playlists, one for each camera associated with the live stream.

Without youtube-dl, your flow might look like this:

Take your video id and make a GET request to the get_video_info endpoint:

HTTP GET: https://www.youtube.com/get_video_info?&video_id=_Gtc-GtLlTk&el=info&ps=default&eurl=&gl=US&hl=en

In the response, the hlsvp value will be the link to the m3u8 HLS playlist:

There is a list of Sqlite wrappers for .Net at http://www.sqlite.org/cvstrac/wiki?p=SqliteWrappers. From what I've heard http://sqlite.phxsoftware.com/ is quite good. This particular one lets you access Sqlite through ADO.Net just like any other database.

To elaborate on previous answers about the "every x units" part, here is what I came up with:

# Draw 5 vertical lines
n = 5

# ... evenly spaced between x0 and x1
x0 = 1.0
x1 = 2.0
dx = (x1-x0)/(n-1.0)

# ... each line going from y0 to y1
y0 = 0
y1 = 10

do for [i = 0:n-1] {
    x = x0 + i*dx
    set arrow from x,y0 to x,y1 nohead linecolor "blue" # add other styling options if needed
}

If all the cases have the same length you can use
switch (mystring.SubString(0,Math.Min(len, mystring.Length))).
Another option is to have a function that will return categoryId based on the string and switch on the id.

Code bellow may help if you want to exclude boolean type from serialization either:

@JsonInclude(JsonInclude.Include.NON_ABSENT)

A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.

Kolorobot’s example application includes the following:

• No-xml Spring MVC 3.2 web application for Servlet 3.0 environment
• Apache Tiles with configuration in place,
• Bootstrap
• JPA 2.0 (Hibernate/HSQLDB)
• JUnit/Mockito
• Spring Security 3.1

I most cases, creating a temporary file named after your variable name might be acceptable. (as you are probably using meaningful variables name...)

Here, my variable name is SSH_PAGEANT_AUTH_SOCK

dir /w "\\.\pipe\\"|find "pageant" > %temp%\SSH_PAGEANT_AUTH_SOCK && set /P SSH_PAGEANT_AUTH_SOCK=<%temp%\SSH_PAGEANT_AUTH_SOCK

web2py has comet_messaging.py, which uses Tornado for websockets look at an example here: http://vimeo.com/18399381 and here vimeo . com / 18232653

I was able to use @rahularyansharma's answer above in my own project, with one minor modification. I needed to get the value of particular cells on the row on which the user clicks a LinkButton. The second line can be modified to get the value of as many cells as you wish.

Here is my solution:

GridViewRow gvr = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
string typecore = gvr.Cells[3].Text.ToString().Trim();

Make sure you have installed 'make' tool through Cygwin's installer.

I ran into the same issue with dnspython.

My solution was to build the source from their official GitHub project.

So my steps were:

git clone https://github.com/rthalley/dnspython
cd dnspython/
python setup.py install

After doing this, I was able to import the dns module.

EDIT

It seems the pip install doesn't work for this module. Install from source as described.

I think this is the syntax you are looking for:

if [ -z != $errorstatus ] 
then
commands
else
commands
fi

As the official documentation says:

body - entity body for PATCH, POST and PUT requests. Must be a Buffer, String or ReadStream. If json is true, then body must be a JSON-serializable object.

When sending JSON you just have to put it in body of the option.

var options = {
    uri: 'https://myurl.com',
    method: 'POST',
    json: true,
    body: {'my_date' : 'json'}
}
request(options, myCallback)
