I can change ActionBar text color by using titleTextColor

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="titleTextColor">#333333</item>
</style>

Wouldn't it be easier to negative-match alphanumerics instead?

return string.match(/^[^a-zA-Z0-9]+$/) ? true : false;

Currently I'm doing an assignment for college, where I can't use certain expressions, such as the ones above, and by looking at the ASCII table, I managed to do it. It's a far more complex code, but it could help others that are restricted like I was.

The first thing to do is to receive the input, in this case, a string of digits; I'll call it String number, and in this case, I'll exemplify it using the number 12, therefore String number = "12";

Another limitation was the fact that I couldn't use repetitive cycles, therefore, a for cycle (which would have been perfect) can't be used either. This limits us a bit, but then again, that's the goal. Since I only needed two digits (taking the last two digits), a simple charAtsolved it:

 // Obtaining the integer values of the char 1 and 2 in ASCII
 int semilastdigitASCII = number.charAt(number.length() - 2);
 int lastdigitASCII = number.charAt(number.length() - 1);

Having the codes, we just need to look up at the table, and make the necessary adjustments:

 double semilastdigit = semilastdigitASCII - 48;  // A quick look, and -48 is the key
 double lastdigit = lastdigitASCII - 48;

Now, why double? Well, because of a really "weird" step. Currently we have two doubles, 1 and 2, but we need to turn it into 12, there isn't any mathematic operation that we can do.

We're dividing the latter (lastdigit) by 10 in the fashion 2/10 = 0.2 (hence why double) like this:

 lastdigit = lastdigit / 10;

This is merely playing with numbers. We were turning the last digit into a decimal. But now, look at what happens:

 double jointdigits = semilastdigit + lastdigit; // 1.0 + 0.2 = 1.2

Without getting too into the math, we're simply isolating units the digits of a number. You see, since we only consider 0-9, dividing by a multiple of 10 is like creating a "box" where you store it (think back at when your first grade teacher explained you what a unit and a hundred were). So:

 int finalnumber = (int) (jointdigits*10); // Be sure to use parentheses "()"

And there you go. You turned a String of digits (in this case, two digits), into an integer composed of those two digits, considering the following limitations:

• No repetitive cycles
• No "Magic" Expressions such as parseInt

Assuming this is a personal certificate created by windows on the system you copied your project from, you can use the certificate manager on the system where the project is now and import the certificate. Start the certificate manager (certmgr) and select the personal certificates then right click below the list of existing certificates and select import from the tasks. Use the browse to find the .pfx in the project (the .pfx from the previous system that you copied over with the project). It should be in the sub-directory with the same name as the project directory. I am familiar with C# and VS, so if that is not your environment maybe the .pfx will be elsewhere or maybe this suggestion does not apply. After the import you should get a status message. If you succeeded, the compile certificate error should be gone.

I used the ../ method to fetch the current project path.

Example: Project1 -- D:\projects

HTML Upload File ASP MVC 3.

Model: (Note that FileExtensionsAttribute is available in MvcFutures. It will validate file extensions client side and server side.)

public class ViewModel
{
    [Required, Microsoft.Web.Mvc.FileExtensions(Extensions = "csv", 
             ErrorMessage = "Specify a CSV file. (Comma-separated values)")]
    public HttpPostedFileBase File { get; set; }
}

HTML View:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new 
                                       { enctype = "multipart/form-data" }))
{
    @Html.TextBoxFor(m => m.File, new { type = "file" })
    @Html.ValidationMessageFor(m => m.File)
}

Controller action:

[HttpPost]
public ActionResult Action(ViewModel model)
{
    if (ModelState.IsValid)
    {
        // Use your file here
        using (MemoryStream memoryStream = new MemoryStream())
        {
            model.File.InputStream.CopyTo(memoryStream);
        }
    }
}

System.setProperty("https.protocols", "TLSv1.2"); worked in my case. Have you checked that within the application?

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body {
  background: #ffd;
}

.div {
  display: inline-block;
  background-color: blue;
  margin-right: 30px;

Try using SweetAlert its just simply the best . You will get a lot of customization and flexibility.

Confirm Example

sweetAlert(
  {
    title: "Are you sure?",
    text: "You will not be able to recover this imaginary file!",
    type: "warning",   
    showCancelButton: true,   
    confirmButtonColor: "#DD6B55",
    confirmButtonText: "Yes, delete it!"
  }, 
  deleteIt()
);

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

Take note of all the MainWindow property settings (WindowStartupLocation, SizeToContent and WindowState) - important for this to work correctly - WindowState for my user case requirement was Maximized

\w is not a word boundary, it matches any word character, including underscores: [a-zA-Z0-9_]. \b is a word boundary, that is, it matches the position between a word and a non-alphanumeric character: \W or [^\w].

These implementations may vary from language to language though.

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.

Looking up a function is easy, just visit http://php.net/<function name> and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.

We immediately learn a couple things about this function by examining its signature:

string date ( string $format [, int $timestamp = time() ] )

First, it returns a string. That's what the first string in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).

date("d-m-Y") // produces something like 03-12-2012

In this code, d represents the day of the month (with a leading 0 is necessary). m represents the month, again with a leading zero if necessary. And Y represents the full 4-digit year. All of these are documented in the aforementioned link.

To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:

h   12-hour format of an hour with leading zeros    01 through 12
i   Minutes with leading zeros                      00 to 59
s   Seconds, with leading zeros                     00 through 59

With this in mind, we can no create a new format string:

date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13

Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

You can do as follow :

import json
exDict = {1:1, 2:2, 3:3}
file.write(json.dumps(exDict))

https://developer.rhino3d.com/guides/rhinopython/python-xml-json/

To show the dots instead of the password set the PasswordTransformationMethod:

yourEditText.setTransformationMethod(new PasswordTransformationMethod());

of course you can set this by default in your edittext element in the xml layout with

android:password

To re-show the readable password, just pass null as transformation method:

yourEditText.setTransformationMethod(null);

Having html collection of selects you can check if every select has option with specific value and filter those which don't match condition:

//get select collection:
let selects = $('select')
//reduce if select hasn't at least one option with value 1
.filter(function () { return [...this.children].some(el => el.value == 1) });

Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.

public ActionResult ClientIdSearch(int cid)
{
  var action = String.Format("Details/{0}", cid);

  return RedirectToAction(action, "Accounts");
}

I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.

5623125698541159 is treated as a single number (out of range of int on most architecture). You need to write numbers in your file as

5 6 2 3 1 2 5  6 9 8 5 4 1 1 5 9  

for 16 numbers.

If your file has input

5,6,2,3,1,2,5,6,9,8,5,4,1,1,5,9 

then change %d specifier in your fscanf to %d,.

  fscanf(myFile, "%d,", &numberArray[i] );  

Here is your full code after few modifications:

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

int main(){

    FILE *myFile;
    myFile = fopen("somenumbers.txt", "r");

    //read file into array
    int numberArray[16];
    int i;

    if (myFile == NULL){
        printf("Error Reading File\n");
        exit (0);
    }

    for (i = 0; i < 16; i++){
        fscanf(myFile, "%d,", &numberArray[i] );
    }

    for (i = 0; i < 16; i++){
        printf("Number is: %d\n\n", numberArray[i]);
    }

    fclose(myFile);

    return 0;
}

Follow this tutorial Tensorflow GPU I did it and it works perfect.

Attention! - install version 9.0! newer version is not supported by Tensorflow-gpu

Steps:

1. Uninstall your old tensorflow
2. Install tensorflow-gpu pip install tensorflow-gpu
3. Install Nvidia Graphics Card & Drivers (you probably already have)
4. Download & Install CUDA
5. Download & Install cuDNN
6. Verify by simple program

from tensorflow.python.client import device_lib print(device_lib.list_local_devices())

Probably a maximized Form helps, or you can do this manually upon form load:

Code Block

this.Location = new Point(0, 0);

this.Size = Screen.PrimaryScreen.WorkingArea.Size;

And then, play with anchoring, so the child controls inside your form automatically fit in your form's new size.

Hope this helps,

Just wrap all that inside a ScrollView

allernhwkim originally posted an answer on this question linking to his blog, however a moderator deleted it. It's the only post I've found which doesn't just tell you how to do the same thing with service, provider and factory, but also tells you what you can do with a provider that you can't with a factory, and with a factory that you can't with a service.

Directly from his blog:

app.service('CarService', function() {
   this.dealer="Bad";
    this.numCylinder = 4;
});

app.factory('CarFactory', function() {
    return function(numCylinder) {
      this.dealer="Bad";
        this.numCylinder = numCylinder
    };
});

app.provider('CarProvider', function() {
    this.dealerName = 'Bad';
    this.$get = function() {
        return function(numCylinder) {
            this.numCylinder = numCylinder;
            this.dealer = this.dealerName;
        }
    };
    this.setDealerName = function(str) {
      this.dealerName = str;
    }      
});

This shows how the CarService will always a produce a car with 4 cylinders, you can't change it for individual cars. Whereas CarFactory returns a function so you can do new CarFactory in your controller, passing in a number of cylinders specific to that car. You can't do new CarService because CarService is an object not a function.

The reason factories don't work like this:

app.factory('CarFactory', function(numCylinder) {
      this.dealer="Bad";
      this.numCylinder = numCylinder
});

And automatically return a function for you to instantiate, is because then you can't do this (add things to the prototype/etc):

app.factory('CarFactory', function() {
    function Car(numCylinder) {
        this.dealer="Bad";
        this.numCylinder = numCylinder
    };
    Car.prototype.breakCylinder = function() {
        this.numCylinder -= 1;
    };
    return Car;
});

See how it is literally a factory producing a car.

The conclusion from his blog is pretty good:

In conclusion,

---------------------------------------------------  
| Provider| Singleton| Instantiable | Configurable|
---------------------------------------------------  
| Factory | Yes      | Yes          | No          |
---------------------------------------------------  
| Service | Yes      | No           | No          |
---------------------------------------------------  
| Provider| Yes      | Yes          | Yes         |       
---------------------------------------------------  

1. Use Service when you need just a simple object such as a Hash, for example {foo;1, bar:2} It’s easy to code, but you cannot instantiate it.

2. Use Factory when you need to instantiate an object, i.e new Customer(), new Comment(), etc.

3. Use Provider when you need to configure it. i.e. test url, QA url, production url.

If you find you're just returning an object in factory you should probably use service.

Don't do this:

app.factory('CarFactory', function() {
    return {
        numCylinder: 4
    };
});

Use service instead:

app.service('CarService', function() {
    this.numCylinder = 4;
});

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

try this C# code to drop your database

        {
            connection.Open();
            using (System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(sql, connection))
            {
                command.CommandType = CommandType.Text;
                command.CommandTimeout = 7200;
                command.ExecuteNonQuery();
            }
            sql = "DROP DATABASE " + dataBase;
            using (System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(sql, connection))
            {
                command.CommandType = CommandType.Text;
                command.CommandTimeout = 7200;
                command.ExecuteNonQuery();
            }
        }
    }

Please always check your certificate expiry date first because most of the certificates have an expiry date. In my case certificate has expired and I was trying to build project.

var startDate = moment(startDateVal, "DD.MM.YYYY");//Date format
var endDate = moment(endDateVal, "DD.MM.YYYY");

var isAfter = moment(startDate).isAfter(endDate);

if (isAfter) {
    window.showErrorMessage("Error Message");
    $(elements.endDate).focus();
    return false;
}

Answer: NO

Here's Why ... I think a key reason for having stored procs in a database is that you're executing SP code in the same process as the SQL engine. This makes sense for database engines designed to work as a network connected service but the imperative for SQLite is much less given that it runs as a DLL in your application process rather than in a separate SQL engine process. So it makes more sense to implement all your business logic including what would have been SP code in the host language.

You can however extend SQLite with your own user defined functions in the host language (PHP, Python, Perl, C#, Javascript, Ruby etc). You can then use these custom functions as part of any SQLite select/update/insert/delete. I've done this in C# using DevArt's SQLite to implement password hashing.

You can use GNU awk:

$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]

$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta
http://www.mysite.net/

Place the var lfckv inside the function. When that line is executed, the body isn't parsed yet and the element "lifecheck" doesn't exist. This works perfectly fine:

function exefunction() {_x000D_
  var lfckv = document.getElementById("lifecheck").checked;_x000D_
  alert(lfckv);_x000D_
}

<label><input id="lifecheck" type="checkbox" >Lives</label>_x000D_
<button onclick="exefunction()">Check value</button>

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

I worked out a working solution to this problem after 2 days of struggle, below solution is perfect for them who want to change few edit text only, change/toggle color through java code, and want to overcome the problems of different behavior on OS versions due to use setColorFilter() method.

This might be a bit more readable:

Date min, max;   // assume these are set to something
Date d;          // the date in question

return d.after(min) && d.before(max);

The Set interface does not provide any ordering guarantees.

Its sub-interface SortedSet represents a set that is sorted according to some criterion. In Java 6, there are two standard containers that implement SortedSet. They are TreeSet and ConcurrentSkipListSet.

In addition to the SortedSet interface, there is also the LinkedHashSet class. It remembers the order in which the elements were inserted into the set, and returns its elements in that order.

It's the Substring method of String, with the first argument set to 0.

 myString.Substring(0,1);

[The following was added by Almo; see Justin J Stark's comment. —Peter O.]

Warning: If the string's length is less than the number of characters you're taking, you'll get an ArgumentOutOfRangeException.

It should be noted as well that this will of course only find all those subclasses that exist on your current classpath. Presumably this is OK for what you are currently looking at, and chances are you did consider this, but if you have at any point released a non-final class into the wild (for varying levels of "wild") then it is entirely feasible that someone else has written their own subclass that you will not know about.

Thus if you happened to be wanting to see all subclasses because you want to make a change and are going to see how it affects subclasses' behaviour - then bear in mind the subclasses that you can't see. Ideally all of your non-private methods, and the class itself should be well-documented; make changes according to this documentation without changing the semantics of methods/non-private fields and your changes should be backwards-compatible, for any subclass that followed your definition of the superclass at least.

I had same issue and the solution was to rename name field in package.json (remove white spaces)

Remove ng.ps1 from the directory C:\Users\%username%\AppData\Roaming\npm\ then try clearing the npm cache at C:\Users\%username%\AppData\Roaming\npm-cache\

You can also use ViewPager.SimpleOnPageChangeListener instead of ViewPager.OnPageChangeListener and override only those methods you want to use.

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

    // optional 
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

    // optional 
    @Override
    public void onPageSelected(int position) { }

    // optional 
    @Override
    public void onPageScrollStateChanged(int state) { }
});

Hope this help :)

Edit: As per android APIs, setOnPageChangeListener (ViewPager.OnPageChangeListener listener) is deprecated. Please check this url:- Android ViewPager API

If you face this issue with Office 365 account. In Exchange Online, by default, the SMTP Client Authentication will be disabled for all Office 365 mailbox accounts. You have to manually enable SMTP Auth for the problematic account and check the case again. Check the below threads.

I ran into this issue while opening the Service Fabric GettingStartedApplication in Visual Studio 2015. The original solution was built on .NET Core in VS 2017 and I got the same error when opening in 2015.

Here are the steps I followed to resolve the issue.

• Right click on (load Failed) project and edit in visual studio.

• Saw the following line in the Project tag: <Project Sdk="Microsoft.NET.Sdk.Web" >

• Followed the instruction shown in the error message to add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to this tag

It should now look like:

<Project Sdk="Microsoft.NET.Sdk.Web" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

• Reloading the project gave me the next error (yours may be different based on what is included in your project)

• Saw that None element had an update attribute as below:

  <None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>
  

• Commented that out as below.

  <!--<None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>-->
  

• Onto the next error: Version in Package Reference is unrecognized

• Saw that Version is there in csproj xml as below (Additional PackageReference lines removed for brevity)

• Stripped the Version attribute

  <PackageReference Include="Microsoft.AspNetCore.Diagnostics" />
  <PackageReference Include="Microsoft.AspNetCore.Mvc" />
  

• I now get the following:

Bingo! The visual Studio One-way upgrade kicked in! Let VS do the magic!

• The Project loaded but with reference lib errors.

• Fixed the reference lib errors individually, by removing and replacing in NuGet to get the project working!

Hope this helps another code traveler :-D

First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps within the class instead move it outside.

I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle

Here is what you want:

import PropTypes from 'prop-types';

class AddAddressComponent extends React.Component {
  render() {
    let { provinceList, cityList } = this.props;
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props');
    }
  }
}

AddAddressComponent.contextTypes = {
  router: PropTypes.object.isRequired
};

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
};

AddAddressComponent.propTypes = {
  userInfo: PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

export default AddAddressComponent;

Assuming the connection is established and is available in global scope;

//Check if a value exists in a table
function record_exists ($table, $column, $value) {
    global $connection;
    $query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
    $result = mysql_query ( $query, $connection );
    if ( mysql_num_rows ( $result ) ) {
        return TRUE;
    } else {
        return FALSE;
    }
}

Usage: Assuming that the value to be checked is stored in the variable $username;

if (record_exists ( 'employee', 'username', $username )){
    echo "Username is not available. Try something else.";
} else {
    echo "Username is available";
}

Update Nov 2020:

To get the list of files modified (and committed!) in the current branch you can use the shortest console command using standard git:

git diff --name-only master...

• If your local "master" branch is outdated (behind the remote), add a remote name (assuming its "origin") git diff --name-only origin/master...

• If you want to include uncommitted changes as well, remove the ...:

  git diff --name-only master

• If you use different main branch name (eg: "main"), substitute it:

  git diff --name-only origin/main...

• If your want to output to stdout (so its copyable)

  git diff --name-only master... | cat

per really nice detailed explanation of different options https://blog.jpalardy.com/posts/git-how-to-find-modified-files-on-a-branch/

You have use to repeat-y as style="background-repeat:repeat-y;width: 200px;" instead of style="repeat-y".

Try this inside the image tag or you can use the below css for the div

.div_backgrndimg
{
    background-repeat: repeat-y;
    background-image: url("/image/layout/lotus-dreapta.png");
    width:200px;
}

If you code C or C++ language. I think we are lucky because we could use a file to input. It is so convenient and clear. I often do that. This is argument to implement it :

{
freopen("inputfile", "r", stdin);
}

Notice that inputfile must locate at same directory with source code file, r is stand for read.

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

You can handle the AppDomain.UnhandledException event

EDIT: actually, this event is probably more adequate: Application.DispatcherUnhandledException

Keep the java script code inside the body tag

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

For Visual Studio for mac, you can find it under Visual Studio -> Preferences -> Text Editor -> Markers and Rulers -> Show invisible characters

Please note you may need to restart Visual Studio for the changes to take effect

def merge(l1, l2, out=[]):
    if l1==[]: return out+l2
    if l2==[]: return out+l1
    if l1[0]<l2[0]: return merge(l1[1:], l2, out+l1[0:1])
    return merge(l1, l2[1:], out+l2[0:1])
def merge_sort(l): return (lambda h: l if h<1 else merge(merge_sort(l[:h]), merge_sort(l[h:])))(len(l)/2)
print(merge_sort([1,4,6,3,2,5,78,4,2,1,4,6,8]))

SELECT array_to_string(array(SELECT a FROM b),', ');

Will do as well.

(WINDOWS - AWS solution)
Solved for windows by putting tripple quotes around files and paths.
Benefits:
1) Prevents excludes that quietly were getting ignored.
2) Files/folders with spaces in them, will no longer kick errors.

    aws_command = 'aws s3 sync """D:/""" """s3://mybucket/my folder/"  --exclude """*RECYCLE.BIN/*""" --exclude """*.cab""" --exclude """System Volume Information/*""" '

    r = subprocess.run(f"powershell.exe {aws_command}", shell=True, capture_output=True, text=True)

Just click on the link written in the error:

and it will show you the dialogs that will help you to install the required sdk for your project.

For multibranch pipeline projects, do this in the script console:

def project = Jenkins.instance.getItemByFullName("YourMultibranchPipelineProjectName")    
project.getAllJobs().each{ item ->   
    
    if(item.name == 'jobName'){ // master, develop, feature/......
      
      item.updateNextBuildNumber(#Number);
      item.saveNextBuildNumber();
      
      println('new build: ' + item.getNextBuildNumber())
    }
}

Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.

The :nth-child CSS3 selector is in fact more capable than you ever imagined!

For example, this will select the last 2 elements of #container:

#container :nth-last-child(-n+2) {}

But this is just the beginning of a beautiful friendship.

• :nth-child Browser Support

#container :nth-last-child(-n+2) {
  background-color: cyan;
}

<div id="container">
 <div>a</div>
 <div>b</div>

Please check your Windows system event log for any errors specifically for the "Event Source: Dhcp". It's very likely a networking error related to DHCP. Address lease time expired or so. It shouldn't be a problem related to the SQL Server or the query itself.

Just search the internet for "The semaphore timeout period has expired" and you'll get plenty of suggestions what might be a solution for your problem. Unfortunately there doesn't seem to be the solution for this problem.

I'd have to recommend NumPy as well

Not only is it faster for doing vector math, but it also has a ton of convenience functions.

If you want something even faster for 1d vectors, try vop

It's similar to MatLab, but free and stuff. Here's an example of what you'd do

from numpy import matrix
a = matrix((2,2,2))
b = matrix((1,1,1))
ret = a - b
print ret
>> [[1 1 1]]

Boom.

I know this is ancient but, here's what I use to detect Win764

On Error Resume Next

Set objWSHShell = CreateObject("WScript.Shell")

strWinVer = objWSHShell.RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\BuildLabEx")

If len(strWinVer) > 0 Then
    arrWinVer = Split(strWinVer,".")
    strWinVer = arrWinVer(2)
End If

Select Case strWinVer
Case "x86fre"
strWinVer = "Win7"
Case "amd64fre"
    strWinVer = "Win7 64-bit"
Case Else
    objWSHShell.Popup("OS Not Recognized")
    WScript.Quit
End Select

You could do the following:

def Lists():

    my_list1 = [30,34,56]
    my_list2 = [29,500,43]

    for element in my_list1:
        print(element >= 30)

    for element in my_list2:
        print(element >= 30)

Lists()

This will return the values that are greater than 30 as True, and the values that are smaller as false.

After reading this thread, I did a little testing on RHEL 5 and here are my results for tarring up the abc directory:

This will exclude the directories error and logs and all files under the directories:

tar cvpzf abc.tgz abc/ --exclude='abc/error' --exclude='abc/logs'

Adding a wildcard after the excluded directory will exclude the files but preserve the directories:

tar cvpzf abc.tgz abc/ --exclude='abc/error/*' --exclude='abc/logs/*'

 <!--Java Script to hide alert message after few second -->
    <script type="text/javascript">

                document.getElementById("<%=divStatusMsg.ClientID %>").style.display = "none";
            }, seconds * 1000);
        };
    </script>
    <!--Java Script to hide alert message after few second -->

You can try this,

UPDATE *tableName* SET *field1* = *your_data*, *field2* = *your_data* ... WHERE 1 = 1;

Well in your case if you want to update your online_status to some value, you can try this,

UPDATE thisTable SET online_status = 'Online' WHERE 1 = 1;

Hope it helps. :D

The background-image can also be used to create an underline. This method handles line breaks.

It has to be shifted down via background-position and repeated horizontally. The line width can be adjusted to some degree using background-size (the background is limited to the content box of the element).

.underline
{
    --color: green;
    font-size: 40px;
    background-image: linear-gradient(var(--color) 0%, var(--color) 100%);
    background-repeat: repeat-x;
    background-position: 0 1.05em;
    background-size: 2px 5px;
}

<span class="underline">
     Underlined<br/>
     Text
</span>

Try like this

String sql = "SELECT t FROM table t";
Query query = em.createQuery(sql);
query.setFirstResult(firstPosition);
query.setMaxResults(numberOfRecords);
List result = query.getResultList();

It should work

UPDATE*

You can also try like this

query.setMaxResults(1).getResultList();

If you don't need to access the toggle from outside the element, this code works without a data variable:

<a @click="e => e.target.classList.toggle('active')"></a>

This would be the simplest answer:

yourView.layer.cornerRadius = 8
yourView.layer.masksToBounds = true
yourView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]

Though many have already answered the difference between Val and var. But one point to notice is that val is not exactly like final keyword.

We can change the value of val using recursion but we can never change value of final. Final is more constant than Val.

def factorial(num: Int): Int = {
 if(num == 0) 1
 else factorial(num - 1) * num
}

Method parameters are by default val and at every call value is being changed.

This is one of the simplest query for the same that I came across and we use it for monitoring as well:

            navigationController?.navigationBar.barTintColor = .brown
        }
    }

This took me 1 hour to figure out what is wrong in my code:(, since I'm using large title, it is hard to change the tintColor with largeTitle, why apple makes it so complicated, so many lines to just make a tintColor of navigationBar.

melt() from the reshape2 package gets you close ...

library(reshape2)
(res <- melt(as.data.frame(mat), id="time"))
#   time variable value
# 1  0.0      C_0   0.1
# 2  0.5      C_0   0.2
# 3  1.0      C_0   0.3
# 4  0.0      C_1   0.3
# 5  0.5      C_1   0.4
# 6  1.0      C_1   0.5

... although you may want to post-process its results to get your preferred column names and ordering.

setNames(res[c("variable", "time", "value")], c("name", "time", "val"))
#   name time val
# 1  C_0  0.0 0.1
# 2  C_0  0.5 0.2
# 3  C_0  1.0 0.3
# 4  C_1  0.0 0.3
# 5  C_1  0.5 0.4
# 6  C_1  1.0 0.5

This is a cheeky answer, but if you are constrained to CSS only and able to reverse your items in the DOM, it might be worth considering. It relies on the fact that while there is no selector for the last element of a specific class, it is actually possible to style the first. The trick is to then use flexbox to display the elements in reverse order.

ul {_x000D_
  display: flex;_x000D_
  flex-direction: column-reverse;_x000D_
}_x000D_
_x000D_
/* Apply desired style to all matching elements. */_x000D_
ul > li.list {_x000D_
  background-color: #888;_x000D_
}_x000D_
_x000D_
/* Using a more specific selector, "unstyle" elements which are not the first. */_x000D_
ul > li.list ~ li.list {_x000D_
  background-color: inherit;_x000D_
}

<ul>_x000D_
  <li class="list">0</li>_x000D_
  <li>1</li>_x000D_
  <li class="list">2</li>_x000D_
</ul>_x000D_
<ul>_x000D_
  <li>0</li>_x000D_
  <li class="list">1</li>_x000D_
  <li class="list">2</li>_x000D_
  <li>3</li>_x000D_
</ul>

Actually, there are some situations which the throw statment will not preserve the StackTrace information. For example, in the code below:

try
{
  int i = 0;
  int j = 12 / i; // Line 47
  int k = j + 1;
}
catch
{
  // do something
  // ...
  throw; // Line 54
}

The StackTrace will indicate that line 54 raised the exception, although it was raised at line 47.

Unhandled Exception: System.DivideByZeroException: Attempted to divide by zero.
   at Program.WithThrowIncomplete() in Program.cs:line 54
   at Program.Main(String[] args) in Program.cs:line 106

In situations like the one described above, there are two options to preseve the original StackTrace:

Calling the Exception.InternalPreserveStackTrace

As it is a private method, it has to be invoked by using reflection:

private static void PreserveStackTrace(Exception exception)
{
  MethodInfo preserveStackTrace = typeof(Exception).GetMethod("InternalPreserveStackTrace",
    BindingFlags.Instance | BindingFlags.NonPublic);
  preserveStackTrace.Invoke(exception, null);
}

I has a disadvantage of relying on a private method to preserve the StackTrace information. It can be changed in future versions of .NET Framework. The code example above and proposed solution below was extracted from Fabrice MARGUERIE weblog.

Calling Exception.SetObjectData

The technique below was suggested by Anton Tykhyy as answer to In C#, how can I rethrow InnerException without losing stack trace question.

static void PreserveStackTrace (Exception e) 
{ 
  var ctx = new StreamingContext  (StreamingContextStates.CrossAppDomain) ; 
  var mgr = new ObjectManager     (null, ctx) ; 
  var si  = new SerializationInfo (e.GetType (), new FormatterConverter ()) ; 

  e.GetObjectData    (si, ctx)  ; 
  mgr.RegisterObject (e, 1, si) ; // prepare for SetObjectData 
  mgr.DoFixups       ()         ; // ObjectManager calls SetObjectData 

  // voila, e is unmodified save for _remoteStackTraceString 
} 

Although, it has the advantage of relying in public methods only it also depends on the following exception constructor (which some exceptions developed by 3rd parties do not implement):

protected Exception(
    SerializationInfo info,
    StreamingContext context
)

In my situation, I had to choose the first approach, because the exceptions raised by a 3rd-party library I was using didn't implement this constructor.

I use Ubuntu linux, and in my case the error was caused by incorrect statement syntax (which I found out by typing perror 150 at the terminal, which gives

MySQL error code 150: Foreign key constraint is incorrectly formed

Changing the syntax of the query from

alter table scale add constraint foreign key (year_id) references year.id;

to

alter table scale add constraint foreign key (year_id) references year(id);

fixed it.

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

You can simply call it:

SubGraphButton_Click(sender, args);

Now, if your SubGraphButton_Click does something with the args, you might be in trouble, but usually you don't do anything with them.

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

also js fiddle here =) http://jsfiddle.net/xQgSm/

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

Be consistent and it doesn't matter which one. Also if for some reason you must interop with another program or tool using a certain DEBUG identifier it's easy to do

#ifdef THEIRDEBUG
#define MYDEBUG
#endif //and vice-versa

You can put an equal formula, then copy it so reference the whole range (one cell goes into one cell)

=Sheet2!A1

If you need to concatenate the results, you'll need a longer formula, or a user-defined function (i.e. macro).

=Sheet2!A1&Sheet2!B1&Sheet2!C1&Sheet2!D1&Sheet2!E1&Sheet2!F1

You can hide a JPanel by calling setVisible(false). For example:

public static void main(String args[]){
    JFrame f = new JFrame();
    f.setLayout(new BorderLayout());
    final JPanel p = new JPanel();
    p.add(new JLabel("A Panel"));
    f.add(p, BorderLayout.CENTER);

    //create a button which will hide the panel when clicked.
    JButton b = new JButton("HIDE");
    b.addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent e){
                p.setVisible(false);
        }
    });

    f.add(b,BorderLayout.SOUTH);
    f.pack();
    f.setVisible(true);
}

First, you need to create selfsigned.key and selfsigned.crt files. Go to Create a Self-Signed SSL Certificate Or do following steps.

Go to the terminal and run the following command.

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./selfsigned.key -out selfsigned.crt

• After that put the following information
• Country Name (2 letter code) [AU]: US
• State or Province Name (full name) [Some-State]: NY
• Locality Name (eg, city) []:NY
• Organization Name (eg, company) [Internet Widgits Pty Ltd]: xyz (Your - Organization)
• Organizational Unit Name (eg, section) []: xyz (Your Unit Name)
• Common Name (e.g. server FQDN or YOUR name) []: www.xyz.com (Your URL)
• Email Address []: Your email

After creation adds key & cert file in your code, and pass the options to the server.

const express = require('express');
const https = require('https');
const fs = require('fs');
const port = 3000;

var key = fs.readFileSync(__dirname + '/../certs/selfsigned.key');
var cert = fs.readFileSync(__dirname + '/../certs/selfsigned.crt');
var options = {
  key: key,
  cert: cert
};

app = express()
app.get('/', (req, res) => {
   res.send('Now using https..');
});

var server = https.createServer(options, app);

server.listen(port, () => {
  console.log("server starting on port : " + port)
});

• Finally run your application using https.

And try deleting the contents of your mac/pc lockdown folder. Here's the link, follow the steps on "Reset the Lockdown folder".

This one worked for me.

You can get your result by simply use substr():

Syntax substr(string,start,length)

Example

<?php
$myStr = "HelloWordl";
echo substr($myStr,0,5);
?>

Output :

 Hello

To check are the following:

1. if the right public key (id_rsa.pub) is uploaded to the git-server.
2. if the right private key (id_rsa) is copied to /var/lib/jenkins/.ssh/
3. if the known_hosts file is created inside ~/.ssh folder. Try ssh -vvv [email protected] to see debug logs. If thing goes well, github.com will be added to known_hosts.
4. if the permission of id_rsa is set to 700 (chmod 700 id_rsa)

After all checks, try ssh -vvv [email protected].

I got another Solution. Subtract parent property value from child property value

$('child-div').offset().top - $('parent-div').offset().top;

I find this image very meaningful :

(from : Oliver Steele -My Git Workflow (2008) )

I know this is old, but I was just working on a project that required me to filter HTML and this worked fine:

noHTMLString.replaceAll("\\&.*?\\;", "");

instead of this:

html = html.replaceAll(" ","");
html = html.replaceAll("&"."");

One way - split you image into N rotating it slightly every time. I'd say 5 is enough. then create something like this in drawable

<animation-list   android:id="@+id/handimation" android:oneshot="false" 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/progress1" android:duration="150" />
    <item android:drawable="@drawable/progress2" android:duration="150" />
    <item android:drawable="@drawable/progress3" android:duration="150" />
 </animation-list> 

code start

progress.setVisibility(View.VISIBLE);
AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.setCallback(progress);
frameAnimation.setVisible(true, true);

code stop

AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.stop();
frameAnimation.setCallback(null);
frameAnimation = null;
progress.setVisibility(View.GONE);

I was looking for same answer and finally I found this link. You can find explained three different ways how to add bootstrap css into your angular 2 project. It helped me.

Here is the link: http://codingthesmartway.com/using-bootstrap-with-angular/

In Java, you really want to use Integer.toString to convert an integer to its corresponding String value. If you are dealing with just the digits 0-9, then you could use something like this:

private static final char[] DIGITS =
    {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

private static char getDigit(int digitValue) {
   assertInRange(digitValue, 0, 9);
   return DIGITS[digitValue];
}

Or, equivalently:

private static int ASCII_ZERO = 0x30;

private static char getDigit(int digitValue) {
  assertInRange(digitValue, 0, 9);
  return ((char) (digitValue + ASCII_ZERO));
}

Thanks for your feed back got it to work I used the sshpass tool.

sshpass -p 'password' scp [email protected]:sys_config /var/www/dev/

Break ends the current loop/control structure and skips to the end of it, no matter how many more times the loop otherwise would have repeated.

Continue skips to the beginning of the next iteration of the loop.

Further to the excellent accepted answer from Nick Craver, you can throttle the scroll event so that it is not fired so frequently thus increasing browser performance:

var _throttleTimer = null;
var _throttleDelay = 100;
var $window = $(window);
var $document = $(document);

$document.ready(function () {

    $window
        .off('scroll', ScrollHandler)
        .on('scroll', ScrollHandler);

});

function ScrollHandler(e) {
    //throttle event:
    clearTimeout(_throttleTimer);
    _throttleTimer = setTimeout(function () {
        console.log('scroll');

        //do work
        if ($window.scrollTop() + $window.height() > $document.height() - 100) {
            alert("near bottom!");
        }

    }, _throttleDelay);
}

and awk as well

awk 'NR!~/^(5|10|25)$/' file

It is very simple.

select DATENAME(month, getdate())

output : January

what u can also do i place an extra "dummy" div before your last div.

Make it 1 px heigh and the width as much needed to cover the container div/body

This will make the last div appear under it, starting from the left.

My second Solution for the error {"ok":true,"result":[]}

1. Go in your Telegram Group
2. Add new User (Invite)
3. Search for "getidsbot" => @getidsbot
4. Message: /start@getidsbot
5. Now you see the ID. looks like 1068773197, which is -1001068773197 for bots (with -100 prefix)!!!
6. Kick the bot from the Group.
7. Now go to the Webbrowser an send this line (Test Message):

https://api.telegram.org/botAPITOKENNUMBER:APITOKENKEYHERE/sendmessage?chat_id=-100GROUPNUMBER&text=test

Edit the API Token and the Group-ID!

Only install the Service Pack (VS10sp1-KB983509.msp) wasn't enough to me.

I had to uninstall the Visual Studio Team Explorer 2010 to continue the installation :)

The solution by dglmtn doesn't work when you have a 9-patch drawable with padding as background. Strange things happen, I don't even want to talk about it, if you have such a problem, you know them.

Now, If you want to have a listview with different states and 9-patch drawables (it would work with any drawables and colors, I think) you have to do 2 things:

1. Set the selector for the items in the list.
2. Get rid of the default selector for the list.

What you should do is first set the row_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_enabled="true" 
     android:state_pressed="true" android:drawable="@drawable/list_item_bg_pressed" />
    <item android:state_enabled="true"
     android:state_focused="true" android:drawable="@drawable/list_item_bg_focused" />
    <item android:state_enabled="true"
     android:state_selected="true" android:drawable="@drawable/list_item_bg_focused" />
    <item
     android:drawable="@drawable/list_item_bg_normal" />
</selector>

Don't forget the android:state_selected. It works like android:state_focused for the list, but it's applied for the list item.

Now apply the selector to the items (row.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="@drawable/row_selector"
>
...
</RelativeLayout>

Make a transparent selector for the list:

<ListView
    android:id="@+id/android:list"
    ...
    android:listSelector="@android:color/transparent"
    />

This should do the thing.

I prefer the following syntax:

Dim number As Integer = 1
Dim str As String = String.TryCast(number)

If str IsNot Nothing Then

Hah you can tell I typically write code in C#. 8)

The reason I prefer TryCast is you do not have to mess with the overhead of casting exceptions. Your cast either succeeds or your variable is initialized to null and you deal with that accordingly.

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

You can also use the struct module to do this:

>>> struct.unpack("<L", "y\xcc\xa6\xbb")[0]
3148270713L

All what you have to do is to select and download the bootstrap.css and bootstrap.js files from Bootswatch website, and then replace the original files with them.

Of course you have to add the paths to your layout page after the jQuery path that is all.

This is what I typically do:

File outputDir = context.getCacheDir(); // context being the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);

As for their deletion, I am not complete sure either. Since I use this in my implementation of a cache, I manually delete the oldest files till the cache directory size comes down to my preset value.

As guruz mentioned, the JIT has several lovely graph/tree layouts, including quite appealing RGraph and HyperTree visualizations.

Also, I've just put up a super simple SVG-based implementation at github (no dependencies, ~125 LOC) that should work well enough for small graphs displayed in modern browsers.

You have to create an instance of one of the subclasses. Stream is an abstract class that can't be instantiated directly.

There are a bunch of choices if you look at the bottom of the reference here:

Stream Class | Microsoft Developer Network

The most common probably being FileStream or MemoryStream. Basically, you need to decide where you wish the data backing your stream to come from, then create an instance of the appropriate subclass.

putExtra() : This method sends the data to another activity and in parameter, we have to pass key-value pair.

Syntax: intent.putExtra("key", value);

Eg: intent.putExtra("full_name", "Vishnu Sivan");

Intent intent=getIntent() : It gets the Intent from the previous activity.

fullname = intent.getStringExtra(“full_name”) : This line gets the string form previous activity and in parameter, we have to pass the key which we have mentioned in previous activity.

The IIS inbound rules as shown in the question DO work. I had to clear the browser cache and add the following line in the top of my <head> section of the index.html page:

<base href="/myApplication/app/" />

This is because I have more than one application in localhost and so requests to other partials were being taken to localhost/app/view1 instead of localhost/myApplication/app/view1

Hopefully this helps someone!

If you label the columns and index of your DataFrame, pandas will automatically supply appropriate labels:

import pandas as pd
values = [[1, 2], [2, 5]]
df = pd.DataFrame(values, columns=['Type A', 'Type B'], 
                  index=['Index 1', 'Index 2'])
df.columns.name = 'Type'
df.index.name = 'Index'
df.plot(lw=2, colormap='jet', marker='.', markersize=10, 
        title='Video streaming dropout by category')

In this case, you'll still need to supply y-labels manually (e.g., via plt.ylabel as shown in the other answers).

It seems like your question has been answered but now you might wonder why char *a = "String" is stored in read-only memory. Well, it is actually left undefined by the c99 standard but most compilers choose to it this way for instances like:

printf("Hello, World\n");

c99 standard(pdf) [page 130, section 6.7.8]:

The declaration:

char s[] = "abc", t[3] = "abc";

defines "plain" char array objects s and t whose elements are initialized with character string literals. This declaration is identical to char

s[] = { 'a', 'b', 'c', '\0' }, t[] = { 'a', 'b', 'c' };

The contents of the arrays are modifiable. On the other hand, the declaration

char *p = "abc";

defines p with type "pointer to char" and initializes it to point to an object with type "array of char" with length 4 whose elements are initialized with a character string literal. If an attempt is made to use p to modify the contents of the array, the behavior is undefined.

If you're using CloudFoundry then you'd have to explicitly push the jar along with the keystore having the certificate.

Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.

The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.

Since iPhones developer option apply on wifi tethering, you can get an iPhone which has iOS 6 and above (and has been set to use for developments with the xcode), set it to emulate the desired network profile, connect your Android device to its hotspot

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

I understand the question is regarding UBUNTU, but I had similar problem in Debian Jessie 64bit and warsongs suggestion worked for it also.
When I ran studio.sh android studio would start, but when I tried to configure the android SDK I got the error
Unable to run mksdcard SDK tool
WHen I tried
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
Got error
E: Package 'lib32bz2-1.0' has no installation candidate
So took warsongs suggestion and only tried to install lib32stdc++6.
sudo apt-get install lib32stdc++6
After this was able to add the Android SDK into Android Studio.

As BalusC indicated, the actionListener by default swallows exceptions, but in JSF 2.0 there is a little more to this. Namely, it doesn't just swallows and logs, but actually publishes the exception.

This happens through a call like this:

context.getApplication().publishEvent(context, ExceptionQueuedEvent.class,                                                          
    new ExceptionQueuedEventContext(context, exception, source, phaseId)
);

The default listener for this event is the ExceptionHandler which for Mojarra is set to com.sun.faces.context.ExceptionHandlerImpl. This implementation will basically rethrow any exception, except when it concerns an AbortProcessingException, which is logged. ActionListeners wrap the exception that is thrown by the client code in such an AbortProcessingException which explains why these are always logged.

This ExceptionHandler can be replaced however in faces-config.xml with a custom implementation:

<exception-handlerfactory>
   com.foo.myExceptionHandler
</exception-handlerfactory>

Instead of listening globally, a single bean can also listen to these events. The following is a proof of concept of this:

@ManagedBean
@RequestScoped
public class MyBean {

    public void actionMethod(ActionEvent event) {

        FacesContext.getCurrentInstance().getApplication().subscribeToEvent(ExceptionQueuedEvent.class, new SystemEventListener() {

        @Override
        public void processEvent(SystemEvent event) throws AbortProcessingException {
            ExceptionQueuedEventContext content = (ExceptionQueuedEventContext)event.getSource();
            throw new RuntimeException(content.getException());
        }

        @Override
        public boolean isListenerForSource(Object source) {
            return true;
        }
        });

        throw new RuntimeException("test");
    }

}

(note, this is not how one should normally code listeners, this is only for demonstration purposes!)

Calling this from a Facelet like this:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
    <h:body>
        <h:form>
            <h:commandButton value="test" actionListener="#{myBean.actionMethod}"/>
        </h:form>
    </h:body>
</html>

Will result in an error page being displayed.

electron-packager

To set the icon on OS X using electron-packager, set the icon using the --icon switch.

It will need to be in .icns format for OS X. There is an online icon converter which can create this file from your .png.

electron-builder

1. Create a directory named build in your project directory and put the .icns the icon in the directory as named icon.icns.
2. run builder by executing command electron-builder --dir.

You will find your application icon will be automatically picked up from that directory location and used for an application while packaging.

Note: The given answer is for recent version of electron-builder and tested with electron-builder v21.2.0

Quickly and Simply I fixed it this way ( I use ADT version: v21.0.0-531062 on Windows XP home edition)

1. Opened manifest file.
2. Changed the Existing project minSdkVersion to the same value as maxSdkVersion ( advise: it may be good to create a New project and see what is it's maxSdkVersion )
3. Save manifest file.
4. Right Click the project and select Build Project.
5. From top menu: Project - Clean.. - check Only the relevant project, below I checked Start a build immediately and Build only the selected projects and OK.
6. open the java file - NO red errors anymore !
7. Back to step 1 above and changing Back minSdkVersion to it's Original value (to supoprt as many Android version as possible).

It worked BUT the problem returns every few days. I do the same as above and it solves and lets me develop.

I faced this error on outdated version of Visual Studio 2010. Due to project configuration I was not able to update this version to newer. Therefore, update of NuGet advised above did not fix things for me.

Root reason for the error in this and similar situations is in dependencies of the package you try to install, which are not compatible with .NET version available in your project.

Universal solution is not obligatory update of Visual Studio or .NET but in installation of older NuGet versions of the same package compatible with your system.

It is not possible to tell for sure, which of earlier versions will work. In my case, this command installed the package without any NuGet updates.

Install-Package X -Version [compatible version number]

Have a look at the java.lang.Character class, it provides a lot of useful methods to convert or test chars.

Answering old thread here (and a bit off-topic) because it's what I found when I was searching how to install Image Magick on Mac OS to run on the local webserver. It's not enough to brew install Imagemagick. You have to also PECL install it so the PHP module is loaded.

From this SO answer:

brew install php
brew install imagemagick
brew install pkg-config
pecl install imagick

And you may need to sudo apachectl restart. Then check your phpinfo() within a simple php script running on your web server.

If it's still not there, you probably have an issue with running multiple versions of PHP on the same Mac (one through the command line, one through your web server). It's beyond the scope of this answer to resolve that issue, but there are some good options out there.

WebElement element = driver.findElement(By.id("foo"));
String contents = (String)((JavascriptExecutor)driver).executeScript("return arguments[0].innerHTML;", element); 

This code really works to get JavaScript from source as well!

For your example, Dirk's answer is perfect. If you instead had a data frame and wanted to add that sort of sequence as a column, you could also use group from groupdata2 (disclaimer: my package) to greedily divide the datapoints into groups.

# Attach groupdata2
library(groupdata2)
# Create a random data frame
df <- data.frame("x" = rnorm(27))
# Create groups with 5 members each (except last group)
group(df, n = 5, method = "greedy")
         x .groups
     <dbl> <fct>  
 1  0.891  1      
 2 -1.13   1      
 3 -0.500  1      
 4 -1.12   1      
 5 -0.0187 1      
 6  0.420  2      
 7 -0.449  2      
 8  0.365  2      
 9  0.526  2      
10  0.466  2      
# … with 17 more rows

There's a whole range of methods for creating this kind of grouping factor. E.g. by number of groups, a list of group sizes, or by having groups start when the value in some column differs from the value in the previous row (e.g. if a column is c("x","x","y","z","z") the grouping factor would be c(1,1,2,3,3).

Below config worked for me. Refer this link for more details.

       jenkins.exe stop
       jenkins.exe start
       jenkins.exe restart

These commands will work from cmd only if you run CMD with admin permissions

To easily understand the problem, imagine we wrote this code:

static void Main(string[] args)
{
    string[] test = new string[3];
    test[0]= "hello1";
    test[1]= "hello2";
    test[2]= "hello3";

    for (int i = 0; i <= 3; i++)
    {
        Console.WriteLine(test[i].ToString());
    }
}

Result will be:

hello1
hello2
hello3

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.

Size of array is 3 (indices 0, 1 and 2), but the for-loop loops 4 times (0, 1, 2 and 3).
So when it tries to access outside the bounds with (3) it throws the exception.

If you *have to* use floats, strictfp keyword may be useful.

You're saying that you need GPS location first if its available, but what you did is first you're getting location from network provider and then from GPS. This will get location from Network and GPS as well if both are available. What you can do is, write these cases in if..else if block. Similar to-

if( !isGPSEnabled && !isNetworkEnabled) {

// Can't get location by any way

} else {

    if(isGPSEnabled) {

    // get location from GPS

    } else if(isNetworkEnabled) {

    // get location from Network Provider

    }
}

So this will fetch location from GPS first (if available), else it will try to fetch location from Network Provider.

EDIT:

To make it better, I'll post a snippet. Consider it is in try-catch:

boolean gps_enabled = false;
boolean network_enabled = false;

LocationManager lm = (LocationManager) mCtx
                .getSystemService(Context.LOCATION_SERVICE);

gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

Location net_loc = null, gps_loc = null, finalLoc = null;

if (gps_enabled)
    gps_loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (network_enabled)
    net_loc = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

if (gps_loc != null && net_loc != null) {

    //smaller the number more accurate result will
    if (gps_loc.getAccuracy() > net_loc.getAccuracy()) 
        finalLoc = net_loc;
    else
        finalLoc = gps_loc;

        // I used this just to get an idea (if both avail, its upto you which you want to take as I've taken location with more accuracy)

} else {

    if (gps_loc != null) {
        finalLoc = gps_loc;
    } else if (net_loc != null) {
        finalLoc = net_loc;
    }
}

Now you check finalLoc for null, if not then return it. You can write above code in a function which returns the desired (finalLoc) location. I think this might help.

I found lots of people meet this problem because the Multi-version Python, on my own vps (cent os 7 x64), I solved it in this way:

1. Find the file "_sqlite3.so"

   find / -name _sqlite3.so
   

   out: /usr/lib64/python2.7/lib-dynload/_sqlite3.so

2. Find the dir of python Standard library you want to use,

   for me /usr/local/lib/python3.6/lib-dynload

3. Copy the file:

   cp   /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python3.6/lib-dynload
   

Finally, everything will be ok.

This answer may be premature, but deno supports running both TS and JS out of the box.

Based on your development environment, moving to Deno (and learning about it) might be too much, but hopefully this answer helps someone in the future.

nth-last-child sounds like it was specifically designed to solve this problem, so I doubt whether there is a more compatible alternative. Support looks pretty decent, though.

git diff for unstaged changes.

git diff --cached for staged changes.

git diff HEAD for both staged and unstaged changes.

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

Your code has no problem. It does print the way you want. Alternatively, you can do this:

printf("%04x",a);

when I ran (as suggested above):

>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b

instead of returning:

[1, 2]

I received this as the return:

<map at 0xb387eb8>

I found I had to use list():

>>> b = list(map(operator.itemgetter(0), a))

to successfully return a list using this suggestion. That said, I'm happy with this solution, thanks. (tested/run using Spyder, iPython console, Python v3.6)

Regarding the problem with "Optimize code" property being UNCHECKED yet the code still compiling as optimized: What finally helped me after trying everything was checking the "Enable unmanaged code debugging" checkbox on the same settings page (Project properties - Debug). It doesn't directly relate to the code optimization, but with this enabled, VS no longer optimizes my library and I can debug.

The Runtime object allows you to execute external command line applications from Java and would therefore allow you to use cURL however as the other answers indicate there is probably a better way to do what you are trying to do. If all you want to do is download a file the URL object will work great.

Find a note here: https://code.visualstudio.com/docs/python/environments#_conda-environments

As noted earlier, the Python extension automatically detects existing conda environments provided that the environment contains a Python interpreter. For example, the following command creates a conda environment with the Python 3.4 interpreter and several libraries, which VS Code then shows in the list of available interpreters:

 conda create -n env-01 python=3.4 scipy=0.15.0 astroid babel 

In contrast, if you fail to specify an interpreter, as with conda create --name env-00, the environment won't appear in the list.

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet>

As one of comments:

db.collection.find().sort({age:-1}).limit(1) // for MAX
db.collection.find().sort({age:+1}).limit(1) // for MIN

it's completely usable but i'm not sure about performance

The accepted answer on this question doesn't seem to work for me. I achieved the same thing with a slightly different method:

IF (select object_id from sys.foreign_keys where [name] = 'FK_TableName_TableName2') IS NOT NULL
BEGIN
    ALTER TABLE dbo.TableName DROP CONSTRAINT FK_TableName_TableName2
END

First execute the below command:

sp_who2

After that execute the below command with SPID, which you got from above command:

KILL {SPID value}

Below is an iterative algorithm in C++ that does not use the STL nor recursion nor conditional nested loops. It is faster that way, it does not perform any element swaps and it does not burden the stack with recursion and it can also be easily ported to ANSI C by substituting mallloc(), free() and printf() for new, delete and std::cout, respectively.

If you want to display the elements with a different or longer alphabet then change the *alphabet parameter to point to a different string than "abcdefg".

void OutputArrayChar(unsigned int* ka, size_t n, const char *alphabet) {
    for (int i = 0; i < n; i++)
        std::cout << alphabet[ka[i]] << ",";
    std::cout << endl;
}
    

void GenCombinations(const unsigned int N, const unsigned int K, const char *alphabet) {
    unsigned int *ka = new unsigned int [K];  //dynamically allocate an array of UINTs
    unsigned int ki = K-1;                    //Point ki to the last elemet of the array
    ka[ki] = N-1;                             //Prime the last elemet of the array.
    
    while (true) {
        unsigned int tmp = ka[ki];  //Optimization to prevent reading ka[ki] repeatedly

        while (ki)                  //Fill to the left with consecutive descending values (blue squares)
            ka[--ki] = --tmp;
        OutputArrayChar(ka, K, alphabet);
    
        while (--ka[ki] == ki) {    //Decrement and check if the resulting value equals the index (bright green squares)
            OutputArrayChar(ka, K, alphabet);
            if (++ki == K) {      //Exit condition (all of the values in the array are flush to the left)
                delete[] ka;
                return;
            }                   
        }
    }
}
    

int main(int argc, char *argv[])
{
    GenCombinations(7, 4, "abcdefg");
    return 0;
}

IMPORTANT: The *alphabet parameter must point to a string with at least N characters. You can also pass an address of a string which is defined somewhere else.

Combinations: Out of "7 Choose 4".

you should read the file, every time you want to add a new property to the json, and then add the the new properties

var fs = require('fs');
fs.readFile('data.json',function(err,content){
  if(err) throw err;
  var parseJson = JSON.parse(content);
  for (i=0; i <11 ; i++){
   parseJson.table.push({id:i, square:i*i})
  }
  fs.writeFile('data.json',JSON.stringify(parseJson),function(err){
    if(err) throw err;
  })
})

I just had the same problem and ended up doing:

git rebase -i HEAD~N

(N is the number of commits git will show you)

That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.

You need to provide an IFormatProvider:

@String.Format(new CultureInfo("en-US"), "{0:C}", @price)

Thanks a lot, it works like this:

java -Djava.rmi.server.hostname=xxx.xxx.xxx.xxx -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=25000 -jar myjar.jar

You don't need to have a reportViewer control anywhere - you can create the LocalReport on the fly:

var lr = new LocalReport
{
    ReportPath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) ?? @"C:\", "Reports", "PathOfMyReport.rdlc"),
    EnableExternalImages = true
};

lr.DataSources.Add(new ReportDataSource("NameOfMyDataSet", model));

string mimeType, encoding, extension;

Warning[] warnings;
string[] streams;
var renderedBytes = lr.Render
    (
        "PDF",
        @"<DeviceInfo><OutputFormat>PDF</OutputFormat><HumanReadablePDF>False</HumanReadablePDF></DeviceInfo>",
        out mimeType,
        out encoding,
        out extension,
        out streams,
        out warnings
    );

var saveAs = string.Format("{0}.pdf", Path.Combine(tempPath, "myfilename"));

var idx = 0;
while (File.Exists(saveAs))
{
    idx++;
    saveAs = string.Format("{0}.{1}.pdf", Path.Combine(tempPath, "myfilename"), idx);
}

using (var stream = new FileStream(saveAs, FileMode.Create, FileAccess.Write))
{
    stream.Write(renderedBytes, 0, renderedBytes.Length);
    stream.Close();
}

lr.Dispose();

You can also add parameters: (lr.SetParameter()), handle subreports: (lr.SubreportProcessing+=YourHandler), or pretty much anything you can think of.

Indeed ADD go /usr/local/ will add content of go folder and not the folder itself, you can use Thomasleveil solution or if that did not work for some reason you can change WORKDIR to /usr/local/ then add your directory to it like:

WORKDIR /usr/local/
COPY go go/

or

WORKDIR /usr/local/go
COPY go ./

But if you want to add multiple folders, it will be annoying to add them like that, the only solution for now as I see it from my current issue is using COPY . . and exclude all unwanted directories and files in .dockerignore, let's say I got folders and files:

- src 
- tmp 
- dist 
- assets 
- go 
- justforfun 
- node_modules 
- scripts 
- .dockerignore 
- Dockerfile 
- headache.lock 
- package.json 

and I want to add src assets package.json justforfun go so:

in Dockerfile:

FROM galaxy:latest

WORKDIR /usr/local/
COPY . .

in .dockerignore file:

node_modules
headache.lock
tmp
dist

Or for more fun (or you like to confuse more people make them suffer as well :P) can be:

*
!src 
!assets 
!go 
!justforfun 
!scripts 
!package.json 

In this way you ignore everything, but excluding what you want to be copied or added only from "ignore list".

It is a late answer but adding more ways to do the same covering even more cases.

Just in case you arrived here because you copied a branch name from Github, note that a remote branch is not automatically also a local branch, so a merge will not work and give the "not something we can merge" error.

In that case, you have two options:

git checkout [branchYouWantToMergeInto]
git merge origin/[branchYouWantToMerge]

or

# this creates a local branch
git checkout [branchYouWantToMerge]

git checkout [branchYouWantToMergeInto]
git merge [branchYouWantToMerge]

I experienced the same problem and following solution solved this problem. You should try the following solution.

sudo mkdir -p /data/db
sudo chown -R 'username' /data/db

Use this command : (Jarsigner is in your Java bin folder goto java->jdk->bin path in cmd prompt)

$ jarsigner -verify my_signed.apk

If the .apk is signed properly, Jarsigner prints "jar verified"

You can create a function in your ~/.bashrc file, so you get a ping command ping-t on your console:

function ping-t { ping "$1" | while read pong; do echo "$(date): $pong"; done; }

Now you can call this on the console:

ping-t example.com

Use $('ul#menu').children('li').length

.size() instead of .length will also work

JavaScript interpreters are single threaded, so a variable can never change, when the code is waiting in some other code that does not change the variable.

In my opinion it would be the best solution to wrap the variable in some kind of object that has a getter and setter function. You can then register a callback function in the object that is called when the setter function of the object is called. You can then use the getter function in the callback to retrieve the current value:

function Wrapper(callback) {
    var value;
    this.set = function(v) {
        value = v;
        callback(this);
    }
    this.get = function() {
        return value;
    }  
}

This could be easily used like this:

<html>
<head>
<script type="text/javascript" src="wrapper.js"></script>
<script type="text/javascript">
function callback(wrapper) {
    alert("Value is now: " + wrapper.get());
}

wrapper = new Wrapper(callback);
</script>
</head>
<body>
    <input type="text" onchange="wrapper.set(this.value)"/>
</body>
</html>

Steveha's answer was helpful to me, but omits an important point (one that I think wisty was getting at). The global keyword is not necessary if you only access but do not assign the variable in the function.

If you assign the variable without the global keyword then Python creates a new local var -- the module variable's value will now be hidden inside the function. Use the global keyword to assign the module var inside a function.

Pylint 1.3.1 under Python 2.7 enforces NOT using global if you don't assign the var.

module_var = '/dev/hello'

def readonly_access():
    connect(module_var)

def readwrite_access():
    global module_var
    module_var = '/dev/hello2'
    connect(module_var)

Well, this seemed to work on my Razor Page and never even did a round trip to the .cs file. This is old html way. It might be useful.

<input type="reset" value="Reset">

SELECT * FROM TableName WHERE CHARINDEX('''',ColumnName) > 0 

When you have column with large amount of nvarchar data and millions of records, general 'LIKE' kind of search using percentage symbol will degrade the performance of the SQL operation.

While CHARINDEX inbuilt TSQL function is much more faster and there won't be any performance loss.

Reference SO post for comparative view.

What worked for me is using _outline not _outlined after the icon name.

<mat-icon>info</mat-icon>

vs

<mat-icon>info_outline</mat-icon>

Sounds like it might be a realative uri. I ran into this problem when doing cross-browser Silverlight; on my blog I mentioned a workaround: pass a "context" uri as the first parameter.

If the uri is realtive, the context uri is used to create a full uri. If the uri is absolute, then the context uri is ignored.

EDIT: You need a "scheme" in the uri, e.g., "ftp://" or "http://"

Look at the help page for load. What load returns is the names of the objects created, so you can look at the contents of isfar to see what objects were created. The fact that nothing else is showing up with ls() would indicate that maybe there was nothing stored in your file.

Also note that load will overwrite anything in your global environment that has the same name as something in the file being loaded when used with default behavior. If you mainly want to examine what is in the file, and possibly use something from that file along with other objects in your global environment then it may be better to use the attach function or create a new environment (new.env) and load the file into that environment using the envir argument to load.

This kind of code perhaps should work for You

SELECT

 CASE
  WHEN (pvc IS NULL OR pvc = '') AND (datepose < 1980) THEN '01'
  WHEN (pvc IS NULL OR pvc = '') AND (datepose >= 1980) THEN '02'

  ELSE '00'

Set the value of the input to null on each onclick event. This will reset the input's value and trigger the onchange event even if the same path is selected.

input.onclick = function () {
    this.value = null;
};

input.onchange = function () {
    alert(this.value);
};?

Here's a DEMO.

Note: It's normal if your file is prefixed with 'C:\fakepath\'. That's a security feature preventing JavaScript from knowing the file's absolute path. The browser still knows it internally.

Dictionaries will use an order that makes searching efficient, and you cant change that,

You could just use a list of objects (a 2 element tuple in a simple case, or even a class), and append items to the end. You can then use linear search to find items in it.

Alternatively you could create or use a different data structure created with the intention of maintaining order.

I had the same problem. The easy way, for me to fix it was to install both the JRE and the eclipse as x86 or x64. When their bit type did not match, eclipse could not find it. So, if it is not a big deal for you to uninstall and reinstall in order to make them match, I would do that.

I ended up installing: Java Runtime Environment 1.7.0.3 (64-bit) and Eclipse Indigo (3.7) (64-bit)

Then it just works.

This example (although not pretty one) can provide more insight into locking mechanism. If incrementA is synchronized, and incrementB is not synchronized, then incrementB will be executed ASAP, but if incrementB is also synchronized then it has to 'wait' for incrementA to finish, before incrementB can do its job.

Both methods are called onto single instance - object, in this example it is: job, and 'competing' threads are aThread and main.

Try with 'synchronized' in incrementB and without it and you will see different results.If incrementB is 'synchronized' as well then it has to wait for incrementA() to finish. Run several times each variant.

class LockTest implements Runnable {
    int a = 0;
    int b = 0;

    public synchronized void incrementA() {
        for (int i = 0; i < 100; i++) {
            this.a++;
            System.out.println("Thread: " + Thread.currentThread().getName() + "; a: " + this.a);
        }
    }

    // Try with 'synchronized' and without it and you will see different results
    // if incrementB is 'synchronized' as well then it has to wait for incrementA() to finish

    // public void incrementB() {
    public synchronized void incrementB() {
        this.b++;
        System.out.println("*************** incrementB ********************");
        System.out.println("Thread: " + Thread.currentThread().getName() + "; b: " + this.b);
        System.out.println("*************** incrementB ********************");
    }

    @Override
    public void run() {
        incrementA();
        System.out.println("************ incrementA completed *************");
    }
}

class LockTestMain {
    public static void main(String[] args) throws InterruptedException {
        LockTest job = new LockTest();
        Thread aThread = new Thread(job);
        aThread.setName("aThread");
        aThread.start();
        Thread.sleep(1);
        System.out.println("*************** 'main' calling metod: incrementB **********************");
        job.incrementB();
    }
}

You can also convert it to an array if you prefer. If Array generics are available:

var args = Array.slice(arguments)

Otherwise:

var args = Array.prototype.slice.call(arguments);

from Mozilla MDN:

You should not slice on arguments because it prevents optimizations in JavaScript engines (V8 for example).

One more way. Select the target table in the left panel in phpMyAdmin, click on Export tab, unselect Data block and click on Go button.

Something like:

var divided = str.split("/~/");
var name=divided[0];
var street = divided[1];

Is probably going to be easiest

Since Spring 4.0+, the best solution is to annotate the test method with @WithMockUser

@Test
@WithMockUser(username = "user1", password = "pwd", roles = "USER")
public void mytest1() throws Exception {
    mockMvc.perform(get("/someApi"))
        .andExpect(status().isOk());
}

Remember to add the following dependency to your project

'org.springframework.security:spring-security-test:4.2.3.RELEASE'

If you just want to throw away everything in your working folder (eg the results of a failed or aborted merge) and revert to a clean previous commit, do a git reset --hard.

PID=`ps -ef | grep syncapp 'awk {print $2}'`

if [[ -z "$PID" ]] then
**Kill -9 $PID**

If it's a server socket, you should call listen() on your socket, and then getsockname() to find the port number on which it is listening:

struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
    perror("getsockname");
else
    printf("port number %d\n", ntohs(sin.sin_port));

As for the IP address, if you use INADDR_ANY then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname() on the socket for a specific connection (which you get from accept()) in order to find out which local IP address is being used on that connection.

Well I found this way :

Oracle SQL Developer (Left top icon) > Preferences > Database > NLS and set the Date Format as MM/DD/YYYY HH24:MI:SS

See How to Make Dialogs.

You can use:

JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green.");

And you can also change the symbol to an error message or an warning. E.g see JOptionPane Features.

SELECT @variable1 = col1, @variable2 = col2
FROM table1
