This regex should do it.

\b[a-z]+-[a-z]+\b 

\b indicates a word-boundary.

I just removed mongo following the instructions here: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/ And then I installed again following the instructions in the given link. Everything worked smoothly!

The Java runtime you try to execute your program with is an earlier version than Java 7 which was the target you compile your program for.

For Ubuntu use

apt-get install openjdk-7-jdk

to get Java 7 as default. You may have to uninstall openjdk-6 first.

Regardless of your situation, heres a working demo that creates markers on the map based on an array of addresses.

http://jsfiddle.net/P2QhE/

Javascript code embedded aswell:

$(document).ready(function () {
    var map;
    var elevator;
    var myOptions = {
        zoom: 1,
        center: new google.maps.LatLng(0, 0),
        mapTypeId: 'terrain'
    };
    map = new google.maps.Map($('#map_canvas')[0], myOptions);

    var addresses = ['Norway', 'Africa', 'Asia','North America','South America'];

    for (var x = 0; x < addresses.length; x++) {
        $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) {
            var p = data.results[0].geometry.location
            var latlng = new google.maps.LatLng(p.lat, p.lng);
            new google.maps.Marker({
                position: latlng,
                map: map
            });

        });
    }

}); 

The quick and dirty way to check what string you need it to look at the generated .resources files.

Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)

Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.

For example in my obj/Bin directory I have the file:

MyLocalisation.Properties.Resources.resources

If the resource files are in the same Class library/Application I would use the following C#

ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());

However, as it sounds like you are using the resources file from a separate Class library/Application you probably want

Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM =  new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);

the time signal is not built into network antennas: you have to use the NTP protocol in order to retrieve the time on a ntp server. there are plenty of ntp clients, available as standalone executables or libraries.

the gps signal does indeed include a precise time signal, which is available with any "fix".

however, if nor the network, nor the gps are available, your only choice is to resort on the time of the phone... your best solution would be to use a system wide setting to synchronize automatically the phone time to the gps or ntp time, then always use the time of the phone.

note that the phone time, if synchronized regularly, should not differ much from the gps or ntp time. also note that forcing a user to synchronize its time may be intrusive, you 'd better ask your user if he accepts synchronizing. at last, are you sure you absolutely need a time that precise ?

You can use the querySelector for that:

document.querySelector('[id^="poll-"]').id;

The selector means: get an element where the attribute [id] begins with the string "poll-".

^ matches the start
* matches any position
$ matches the end

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

I just hit this same exception in a WPF project. The issue occurred within an assembly that we recently moved to another namespace (ProblemAssembly.Support to ProblemAssembly.Controls). The exception was happening when trying to access resources from a second resource file that exists in the assembly.

Turns out the additional resource file did not properly move references from the old namespace name to the new namespace name.

In the designer.cs for the resource file, there is a static property to get the ResourceManager. Within that getter, the string was still referring the old namespace. Once correcting it to the new namespace, the problem was resolved:

global::System.Resources.ResourceManager temp = 
     new global::System.Resources.ResourceManager(
          "ProblemAssembly.Support.Properties.Stuff", typeof(Stuff).Assembly);

should have been:

global::System.Resources.ResourceManager temp = 
     new global::System.Resources.ResourceManager(
          "ProblemAssembly.Controls.Properties.Stuff", typeof(Stuff).Assembly);

Hope this helps the next person.

Because I am pre-compiling my web application (using VS2012 publish feature). I was getting the error above. I tried all the suggestions, but weirdly changing 'Build Action' to 'Content' did the trick!

I see a lot of examples of the Microsoft Dispose pattern which is really an anti-pattern. As many have pointed out the code in the question does not require IDisposable at all. But if you where going to implement it please don't use the Microsoft pattern. Better answer would be following the suggestions in this article:

https://www.codeproject.com/Articles/29534/IDisposable-What-Your-Mother-Never-Told-You-About

The only other thing that would likely be helpful is suppressing that code analysis warning... https://docs.microsoft.com/en-us/visualstudio/code-quality/in-source-suppression-overview?view=vs-2017

In WSDL, if you look at the Binding section, you will clearly see that soap binding is explicitly mentioned if the service uses soap 1.2. refer the below sample.

<binding name="EmployeeServiceImplPortBinding" type="tns:EmployeeServiceImpl">
<soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="findEmployeeById">
    <soap12:operation soapAction=""/>
    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>
</operation><operation name="create">
    <soap12:operation soapAction=""/>
    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>
</operation>
</binding>

if the web service use soap 1.1, it will not explicitly define any soap version in the WSDL file under binding section. refer the below sample.

<binding name="EmployeeServiceImplPortBinding" type="tns:EmployeeServiceImpl">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/>
<operation name="findEmployeeById">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation><operation name="create">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation>
</binding>

How to determine the SOAP version of the SOAP message?

but remember that this is not much recommended way to determine the soap version that your web services uses. the version of the soap message can be determined using one of following ways.

1. checking the namespace of the soap message

SOAP 1.1  namespace : http://schemas.xmlsoap.org/soap/envelope

SOAP 1.2 namespace  : http://www.w3.org/2003/05/soap-envelope

2. checking the transport binding information (http header information) of the soap message

SOAP 1.1 : user text/xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: text/xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

SOAP 1.2 : user application/soap+xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: application/soap+xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

3. using SOAP fault information

The structure of a SOAP fault message between the two versions are different.

Also had this problem - in my case it was caused by having the "Specific Version" property on a number of references set to true. Changing this to false on those references resolved the issue.

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

Not an answer, per se, but an observation that seems to have been overlooked.

The description for carat ranges:

see: https://github.com/npm/node-semver#caret-ranges-123-025-004

Allows changes that do not modify the left-most non-zero digit in the [major, minor, patch] tuple.

Means that ^10.2.3 matches 10.2.3 <= v < 20.0.0

I don't think that's what they meant. Pulling in versions 11.x.x through 19.x.x will break your code.

I think they meant left most non-zero number field. There is nothing in SemVer that requires number-fields to be single-digit.

The timer has special functions.

1. Call an asynchronous timer or synchronous timer.
2. Change the time interval
3. Ability to cancel and resume

Escape characters are dependent on whatever system is interpreting them. \n is interpreted as a newline character by many programming languages, but that doesn't necessarily hold true for the other utilities you mention. Even if they do treat \n as newline, there may be some other techniques to get them to behave how you want. You would have to consult their documentation (or see other answers here).

For DOS/Windows systems, the newline is actually two characters: Carriage Return (ASCII 13, AKA \r), followed by Line Feed (ASCII 10). On Unix systems (including Mac OSX) it's just Line Feed. On older Macs it was a single Carriage Return.

In Typescript 1.5 and later, you can use for..of as opposed to for..in

var numbers = [1, 2, 3];

for (var number of numbers) {
    console.log(number);
}

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

this is what worked for us to get the apache accessible from outside:

sudo iptables -I INPUT 4 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
sudo service iptables restart

Pylint message control is documented in the Pylint manual:

Is it possible to locally disable a particular message?

Yes, this feature has been added in Pylint 0.11. This may be done by adding # pylint: disable=some-message,another-one at the desired block level or at the end of the desired line of code.

You can use the message code or the symbolic names.

For example,

def test():
    # Disable all the no-member violations in this function
    # pylint: disable=no-member
    ...

global VAR # pylint: disable=global-statement

The manual also has further examples.

There is a wiki that documents all Pylint messages and their codes.

Take a look at MultiValueDictionary from Microsoft.

Example Code:

MultiValueDictionary<string, string> Parameters = new MultiValueDictionary<string, string>();

Parameters.Add("Malik", "Ali");
Parameters.Add("Malik", "Hamza");
Parameters.Add("Malik", "Danish");

//Parameters["Malik"] now contains the values Ali, Hamza, and Danish

You need the table name/alias in the SELECT part (maybe (vg.id, name)) :

SELECT (vg.id, name) FROM v_groups vg 
inner join people2v_groups p2vg on vg.id = p2vg.v_group_id
where p2vg.people_id =0;

Since dates are converted to UNIX epoch (numbers), you can use Math.max/min to find those:

var maxDate = Math.max.apply(null, dates)
// convert back to date object
maxDate = new Date(maxDate)

(tested in chrome only, but should work in most browsers)

The problem is that [...] in python has two distinct meanings

1. expr [ index ] means accessing an element of a list
2. [ expr1, expr2, expr3 ] means building a list of three elements from three expressions

In your code you forgot the comma between the expressions for the items in the outer list:

[ [a, b, c] [d, e, f] [g, h, i] ]

therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.

The correct syntax for what you're looking for is

[ [a, b, c], [d, e, f], [g, h, i] ]

You can access the form over the event:

e.target.reset();

Glide is a really elegant package management for Go especially if you come from Node's npm or Rust's cargo.

It behaves closely to Godep's new vendor feature in 1.6 but is way more easier. Your dependencies and versions are "locked" inside your projectdir/vendor directory without relying on GOPATH.

Install with brew (OS X)

$ brew install glide

Init the glide.yaml file (akin to package.json). This also grabs the existing imported packages in your project from GOPATH and copy then to the project's vendor/ directory.

$ glide init

Get new packages

$ glide get vcs/namespace/package

Update and lock the packages' versions. This creates glide.lock file in your project directory to lock the versions.

$ glide up

I tried glide and been happily using it for my current project.

jQuery has a function that can do this:

1. include the following script in your head:

   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script>
   

   (or just download the jQuery.js file online and include it locally)

2. use this script to toggle the check box when the input is clicked:

   var toggle = false;
   $("#INPUTNAMEHERE").click(function() {
           $("input[type=checkbox]").attr("checked",!toggle);
           toggle = !toggle;
   }); 
   

That should do what you want if I understood what you were trying to do.

None of the answers above, at least to me, show how to actually handle determining whether you have 1 item or multiple, and how to actually get the values out of your items in a generic way that doesn't depend on there actually only being one item, or multiple, so I'm throwing my hat in the ring.

This is quite easily and generically done by checking your count to see that you have at least one item, then doing a foreach loop on the .SelectedItems, casting each item as a DataRowView:

if (listView1.SelectedItems.Count > 0)
{
     foreach (DataRowView drv in listView1.SelectedItems)
     {
         string firstColumn = drv.Row[0] != null ? drv.Row[0].ToString() : String.Empty;
         string secondColumn = drv.Row[1] != null ? drv.Row[1].ToString() : String.Empty;
         // ... do something with these values before they are replaced
         // by the next run of the loop that will get the next row
     }
}

This will work, whether you have 1 item or many. It's funny that MSDN says to use ListView.SelectedListViewItemCollection to capture listView1.SelectedItems and iterate through that, but I found that this gave an error in my WPF app: The type name 'SelectedListViewItemCollection' does not exist in type 'ListView'.

We can use like below as well

SELECT * 
FROM dbo.March2010 A
WHERE CAST(A.Date AS Date) >= '2017-03-22';

SELECT * 
    FROM dbo.March2010 A
    WHERE CAST(A.Date AS Datetime) >= '2017-03-22 06:49:53.840';

The latest Java Web Start has been enhanced to allow good offline operation as well as allowing "local installation". It is worth looking into.

EDIT 2018: Java Web Start is no longer bundled with the newest JDK's. Oracle is pushing towards a "deploy your app locally with an enclosed JRE" model instead.

You can easily redirect different parts of your shell script to a file (or several files) using sub-shells:

{
  command1
  command2
  command3
  command4
} > file1
{
  command5
  command6
  command7
  command8
} > file2

I don't see how you can compile a project with the C# compiler (or the VB compiler) and not have it balk at the wrong language for the compiler.

Keep your C# code in a separate project from your VB project. You can include these projects into the same solution.

CHAR is fixed length and VARCHAR is variable length. CHAR always uses the same amount of storage space per entry, while VARCHAR only uses the amount necessary to store the actual text.

Shed Skin is "a (restricted) Python-to-C++ compiler".

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

I tried all the solutions mentioned above, then did not work. I have 3 tables one below the other. The last one over flowed. I fixed it using:

/* Grid Definition */
table {
    word-break: break-word;
}

For IE11 in edge mode, you need to set this to word-break:break-all

For larger form instead of writing css classed for every field you could to this

class UserRegistration(forms.ModelForm):
   # list charfields

   class Meta:
      model = User
      fields = ('username', 'first_name', 'last_name', 'email', 'password', 'password2')

   def __init__(self, *args, **kwargs):
      super(UserRegistration, self).__init__(*args, **kwargs)
      for field in self.fields:
         self.fields[field].widget.attrs['class'] = 'form-control'

Here is a function that will load CSS files with a success or failure callback. The failure callback will be called just once, if one or more resources fail to load. I think this approach is better than some of the other solutions because inserting a element into the DOM with an HREF causes an additional browser request (albeit, the request will likely come from cache, depending on response headers).

function loadCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            return $.get(url, function(css) {
                $("<style>" + css + "</style>").appendTo("head");
            });
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

Usage as so:

loadCssFiles(["https://test.com/style1.css", "https://test.com/style2.css",],
    function() {
    alert("All resources loaded");
}, function() {
    alert("One or more resources failed to load");
});

Here is another function that will load both CSS and javascript files:

function loadJavascriptAndCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            if(url.endsWith(".css")) {
                return $.get(url, function(css) {
                    $("<style>" + css + "</style>").appendTo("head");
                });
            } else {
                return $.getScript(url);
            }
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

With Angular 1.3+ you can no longer use global controller declaration on the global scope (Without explicit registration). You would need to register the controller using module.controller syntax.

Example:-

angular.module('app', [])
    .controller('ContactController', ['$scope', function ContactController($scope) {
        $scope.contacts = ["[email protected]", "[email protected]"];

        $scope.add = function() {
            $scope.contacts.push($scope.newcontact);
            $scope.newcontact = "";

        };
    }]);

or

function ContactController($scope) {
    $scope.contacts = ["[email protected]", "[email protected]"];

    $scope.add = function() {
        $scope.contacts.push($scope.newcontact);
        $scope.newcontact = "";
    };
}
ContactController.$inject = ['$scope'];
angular.module('app', []).controller('ContactController', ContactController);

It is a breaking change but it can be turned off to use globals by using allowGlobals.

Example:-

angular.module('app')
    .config(['$controllerProvider', function($controllerProvider) {
        $controllerProvider.allowGlobals();
    }]);

Here is the comment from Angular source:-

• check if a controller with given name is registered via $controllerProvider
• check if evaluating the string on the current scope returns a constructor
• if $controllerProvider#allowGlobals, check window[constructor] on the global window object (not recommended)

 .....

expression = controllers.hasOwnProperty(constructor)
            ? controllers[constructor]
            : getter(locals.$scope, constructor, true) ||
                (globals ? getter($window, constructor, true) : undefined);

Some additional checks:-

• Do Make sure to put the appname in ng-app directive on your angular root element (eg:- html) as well. Example:- ng-app="myApp"

• If everything is fine and you are still getting the issue do remember to make sure you have the right file included in the scripts.

• You have not defined the same module twice in different places which results in any entities defined previously on the same module to be cleared out, Example angular.module('app',[]).controller(.. and again in another place angular.module('app',[]).service(.. (with both the scripts included of course) can cause the previously registered controller on the module app to be cleared out with the second recreation of module.

For markdown table syntax see:

https://www.markdownguide.org/extended-syntax/#tables

Quick summary:

To quickly understand the syntax used in other answers, it helps to start from a more complete intuitive and easier to remember syntax, and then a minimalized version with the same result.

Basic example:

| Header A       | Header B       |
| -------------- | -------------- |
| row 1 col 1    | row 1 col 2    |
| row 2 column 1 | row 2 column 2 |

Same result in a more minimalist form (cell widths can vary) :

Header A | Header B
--- | ---
row 1 col 1 | row 1 col 2
row 2 column 1 | row 2 column 2

And more related to the question: side by side images with labels on top:

label 1 | label 2
--- | ---
![](https://...image1.png) | ![](https://...image2.png)

( use :--- , ---: , and :---: for (text) alignment in the column, respectively: left, right, center )

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

To avoid this warning, instead of using:

parseInt("999", 10);

You may replace it by:

Number("999");

^{Note that parseInt and Number have different behaviors, but in some cases, one can replace the other.}

You might use flush to force validation constraints to be realised and detected in a known place rather than when the transaction is committed. It may be that commit gets called implicitly by some framework logic, through declarative logic, the container, or by a template. In this case, any exception thrown may be difficult to catch and handle (it could be too high in the code).

For example, if you save() a new EmailAddress object, which has a unique constraint on the address, you won't get an error until you commit.

Calling flush() forces the row to be inserted, throwing an Exception if there is a duplicate.

However, you will have to roll back the session after the exception.

grep

Select-String cmdlet and -match operator work with regexes. Also you can directly make use of .NET's regex support for more advanced functionality.

sort

Sort-Object is more powerful (than I remember *nix's sort). Allowing multi-level sorting on arbitrary expressions. Here PowerShell's maintenance of underlying type helps; e.g. a DateTime property will be sorted as a DateTime without having to ensure formatting into a sortable format.

uniq

Select-Object -Unique

Perl (how close does PowerShell come to Perl capabilities?)

In terms of Perl's breadth of domain specific support libraries: nowhere close (yet).

For general programming, PowerShell is certainly more cohesive and consistent, and easier to extend. The one gap for text munging is something equivalent to Perl's .. operator.

AWK

It has been long enough since using AWK (must be >18 years, since later I just used Perl), so can't really comment.

sed

[See above]

file (the command that gives file information)

PowerShell's strength here isn't so much of what it can do with filesystem objects (and it gets full information here, dir returns FileInfo or FolderInfo objects as appropriate) is that is the whole provider model.

You can treat the registry, certificate store, SQL Server, Internet Explorer's RSS cache, etc. as an object space navigable by the same cmdlets as the filesystem.

PowerShell is definitely the way forward on Windows. Microsoft has made it part of their requirements for future non-home products. Hence rich support in Exchange, support in SQL Server. This is only going to expand.

A recent example of this is the TFS PowerToys. Many TFS client operations are done without having to startup tf.exe each time (which requires a new TFS server connection, etc.) and is notably easier to then further process the data. As well as allowing wide access to the whole TFS client API to a greater detail than exposed in either Team Explorer of TF.exe.

Try installing tensorflow again with the whatever version you want and with option --ignore-installed like:

pip install tensorflow==1.2.0 --ignore-installed

I solved same issue using this command.

Keystore is used by a server to store private keys, and Truststore is used by third party client to store public keys provided by server to access. I have done that in my production application. Below are the steps for generating java certificates for SSL communication:

1. Generate a certificate using keygen command in windows:

keytool -genkey -keystore server.keystore -alias mycert -keyalg RSA -keysize 2048 -validity 3950

2. Self certify the certificate:

keytool -selfcert -alias mycert -keystore server.keystore -validity 3950

3. Export certificate to folder:

keytool -export -alias mycert -keystore server.keystore -rfc -file mycert.cer

4. Import Certificate into client Truststore:

keytool -importcert -alias mycert -file mycert.cer -keystore truststore

    --DROP TABLE #Employee
    CREATE TABLE #Employee(EmpId BIGINT IDENTITY,EmpName VARCHAR(25),Designation VARCHAR(25),ManagerID BIGINT)

    INSERT INTO #Employee VALUES('M11M','Manager',NULL)
    INSERT INTO #Employee VALUES('P11P','Manager',NULL)

    INSERT INTO #Employee VALUES('AA','Clerk',1)
    INSERT INTO #Employee VALUES('AB','Assistant',1)
    INSERT INTO #Employee VALUES('ZC','Supervisor',2)
    INSERT INTO #Employee VALUES('ZD','Security',2)


    SELECT * FROM #Employee (NOLOCK)

    ;
    WITH Emp_CTE 
    AS
    (
        SELECT EmpId,EmpName,Designation, ManagerID
              ,CASE WHEN ManagerID IS NULL THEN EmpId ELSE ManagerID END ManagerID_N
        FROM #Employee  
    )
    select EmpId,EmpName,Designation, ManagerID
    FROM Emp_CTE
    order BY ManagerID_N, EmpId

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

If you want to are faced with a very large / huge file and want to read faster (imagine you are in a Topcoder/Hackerrank coding competition), you might read a considerably bigger chunk of lines into a memory buffer at one time, rather than just iterate line by line at file level.

buffersize = 2**16
with open(path) as f: 
    while True:
        lines_buffer = f.readlines(buffersize)
        if not lines_buffer:
            break
        for line in lines_buffer:
            process(line)

On Debian 7.0, 64-bit (Wheezy), just run:

sudo apt-get install libpq-dev

After you successfully installed libpq-dev, run:

bundle install

For me

sudo apt-get install php5-mcrypt 

solved the issue

In Pyspark, using parenthesis around each condition is the key to using multiple column names in the join condition.

joined_df = df1.join(df2, 
    (df1['name'] == df2['name']) &
    (df1['phone'] == df2['phone'])
)

If you are using Spring, you can force validation by annotating the class with @Validated:

import org.springframework.validation.annotation.Validated;

I got the same error when I just copied the complete line but when I rewrite the code again i.e. instead of copy-paste, writing it completely then the error was no longer present.

Conclusion: There might be some unacceptable words to the language got copied giving rise to this error.

If you want to calculate your own location, then first set StartPosition to FormStartPosition.Manual:

Form Child = new Form();
Child.StartPosition = FormStartPosition.Manual;
Child.Location = new Point(Location.X + (Width - Child.Width) / 2, Location.Y + (Height - Child.Height) / 2);
Child.Show(this);

Where this is the main/parent form, just like Location.X.

Default value for StartPosition is FormStartPosition.CenterParent and therefore it changes the child's location after showing.

I had angular-cli version 1.0.0-beta.28.3, and the only thing that worked for me was deleting the angular-cli directly from the global node_modules folder:

cd /usr/local/bin/lib/node_modules
rm -rf angular-cli

After that ng version output was, as expected:

command not found: ng

And I could install the latest angular-cli version:

npm install -g @angular/cli@latest

Hope it helps...

• Short version of (correct) tzaman answer will be (for fresh SVN)

  svn switch ^/branches/v1p2p3
  

• --relocate switch is deprecated anyway, when it needed you'll have to use svn relocate command

• Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)

On Windows, the caret character (^) must be escaped:

 dateadd(dd,0, datediff(dd,0, YOURDATE))
 e.g.
 dateadd(dd,0, datediff(dd,0, getDate()))

Visual Studio Code 0.10.10 introduced this feature. To configure it, go to menu File → Preferences → Settings and add this to to your user or workspace settings:

"editor.rulers": [80,120]

The color of the rulers can be customized like this:

"workbench.colorCustomizations": {
    "editorRuler.foreground": "#ff4081"
}

try this

@Html.DropDownList("ddlcountry",(List<SelectListItem>)ViewBag.countrydrop,"Select country")

In Controller

ViewBag.countrydrop = ds.getcountry().Select(x => new SelectListItem { Text = x.country, Value = x.countryid.ToString() }).ToList();

The tricky part is a regex that includes a dash as one of the valid characters in a character class. The dash has to come immediately after the start for a (normal) character class and immediately after the caret for a negated character class. If you need a close square bracket too, then you need the close square bracket followed by the dash. Mercifully, you only need dash, hence the notation chosen.

grep '^[-d]rwx.*[0-9]$' "$@"

See: Regular Expressions and grep for POSIX-standard details.

yan.kun was on the right track but this is much much easier.

    public FileContentResult DownloadCSV()
    {

    }

You can use the built in cache attribute to prevent caching.

For .net Framework: [OutputCache(NoStore = true, Duration = 0)]

For .net Core: [ResponseCache(NoStore = true, Duration = 0)]

Be aware that it is impossible to force the browser to disable caching. The best you can do is provide suggestions that most browsers will honor, usually in the form of headers or meta tags. This decorator attribute will disable server caching and also add this header: Cache-Control: public, no-store, max-age=0. It does not add meta tags. If desired, those can be added manually in the view.

Additionally, JQuery and other client frameworks will attempt to trick the browser into not using it's cached version of a resource by adding stuff to the url, like a timestamp or GUID. This is effective in making the browser ask for the resource again but doesn't really prevent caching.

On a final note. You should be aware that resources can also be cached in between the server and client. ISP's, proxies, and other network devices also cache resources and they often use internal rules without looking at the actual resource. There isn't much you can do about these. The good news is that they typically cache for shorter time frames, like seconds or minutes.

You may write to a file using fs (file system) module.

Here is an example of how you may do it:

const fs = require('fs');

const writeToFile = (fileName, callback) => {
  fs.open(fileName, 'wx', (error, fileDescriptor) => {
    if (!error && fileDescriptor) {
      // Do something with the file here ...
      fs.writeFile(fileDescriptor, newData, (error) => {
        if (!error) {
          fs.close(fileDescriptor, (error) => {
            if (!error) {
              callback(false);
            } else {
              callback('Error closing the file');
            }
          });
        } else {
          callback('Error writing to new file');
        }
      });
    } else {
      callback('Could not create new file, it may already exists');
    }
  });
};

You might also want to get rid of this callback-inside-callback code structure by useing Promises and async/await statements. This will make asynchronous code structure much more flat. For doing that there is a handy util.promisify(original) function might be utilized. It allows us to switch from callbacks to promises. Take a look at the example with fs functions below:

// Dependencies.
const util = require('util');
const fs = require('fs');

// Promisify "error-back" functions.
const fsOpen = util.promisify(fs.open);
const fsWrite = util.promisify(fs.writeFile);
const fsClose = util.promisify(fs.close);

// Now we may create 'async' function with 'await's.
async function doSomethingWithFile(fileName) {
  const fileDescriptor = await fsOpen(fileName, 'wx');

  // Do something with the file here...

  await fsWrite(fileDescriptor, newData);
  await fsClose(fileDescriptor);
}

EDITED: turns out that I had forgotten the quotes needed for $entry in order to print correctly and not give the "no such file or directory" error. Thank you all so much for helping me!

Here is my final code:

    echo "Please type in the directory you want all the files to be listed with last modified dates" #bash can't find file creation dates

read directory

for entry in "$directory"/*

do
modDate=$(stat -c %y "$entry") #%y = last modified. Qoutes are needed otherwise spaces in file name with give error of "no such file"
modDate=${modDate%% *} #%% takes off everything off the string after the date to make it look pretty
echo $entry:$modDate

Prints out like this:

I had a problem with mime types and where making tests for few file types. It looks like each browser sends it's variation of a mime type for a specific file. I was trying to upload mp3 and zip files with open source php class, that what I have found:

• Firefox (mp3): audio/mpeg
• Firefox (zip): application/zip
• Chrome (mp3): audio/mp3
• Chrome (zip): application/octet-stream
• Opera (mp3): audio/mp3
• Opera (zip): application/octet-stream
• IE (mp3): audio/mpeg
• IE (zip): application/x-zip-compressed

So if you need several file types to upload, you better make some tests so that every browser could upload a file and pass mime type check.

Use the built-in sp_msforeachtable stored procedure.

To disable all constraints:

EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT ALL";

To enable all constraints:

EXEC sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL";

To drop all the tables:

EXEC sp_msforeachtable "DROP TABLE ?";

There`s my solution. It will compare arrays which also have objects and arrays. Elements can be stay in any positions. Example:

const array1 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];
const array2 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];

const arraysCompare = (a1, a2) => {
  if (a1.length !== a2.length) return false;
  const objectIteration = (object) => {
    const result = [];
    const objectReduce = (obj) => {
      for (let i in obj) {
        if (typeof obj[i] !== 'object') {
          result.push(`${i}${obj[i]}`);
        } else {
          objectReduce(obj[i]);
        }
      }
    };
    objectReduce(object);
    return result;
  };
  const reduceArray1 = a1.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const reduceArray2 = a2.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const compare =  reduceArray1.map(item => reduceArray2.includes(item));
  return compare.reduce((acc, item) => acc + Number(item)) === a1.length;
};

console.log(arraysCompare(array1, array2));

If increasing the number of visible options is available, the following might work for you:

<html>
    <head>
        <title>Select Option Tooltip Test</title>
        <script>
            function showIETooltip(e){

                var optionCount = obj.options.length;
                var eX = e.offsetX;
                var eY = e.offsetY;

                //vertical position within select will roughly give the moused over option...
                var hoverOptionIndex = Math.floor(eY / (objHeight / optionCount));

                var tooltip = document.getElementById('dvDiv');

Using aggregate is the right approach, but you need to $unwind the list array before applying the $match so that you can filter individual elements and then use $group to put it back together:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $unwind: '$list'},
    { $match: {'list.a': {$gt: 3}}},
    { $group: {_id: '$_id', list: {$push: '$list.a'}}}
])

outputs:

{
  "result": [
    {
      "_id": ObjectId("512e28984815cbfcb21646a7"),
      "list": [
        4,
        5
      ]
    }
  ],
  "ok": 1
}

MongoDB 3.2 Update

Starting with the 3.2 release, you can use the new $filter aggregation operator to do this more efficiently by only including the list elements you want during a $project:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $project: {
        list: {$filter: {
            input: '$list',
            as: 'item',
            cond: {$gt: ['$$item.a', 3]}
        }}
    }}
])

Dim thisMonth As New DateTime(DateTime.Today.Year, DateTime.Today.Month, 1)
Dim firstDayLastMonth As DateTime
Dim lastDayLastMonth As DateTime

firstDayLastMonth = thisMonth.AddMonths(-1)
lastDayLastMonth = thisMonth.AddDays(-1)

You can tell Eclipse to ignore these serialVersionUID warnings:

Window > Preferences > Java > Compiler > Errors / Warnings > Potential Programming Problems

In case you didn't know, there are a lot of other warnings you can enable in this section (or even have some reported as errors), many are very useful:

• Potential Programming Problems: Possible accidental boolean assignment
• Potential Programming Problems: Null pointer access
• Unnecessary code: Local variable is never read
• Unnecessary code: Redundant null check
• Unnecessary code: Unnecessary cast or 'instanceof'

and many more.

This worked for me as-
HTML-

    <div style="background-color: #535; width: 100%; height: 80px;">
        <div class="center">
            Test <br>
            kumar adnioas<br>
            sanjay<br>
            1990
        </div>
    </div> 

CSS-

.center {
    position: relative;
    left: 50%;
    top: 50%;
    height: 82%;
    transform: translate(-50%, -50%);
    transform: -webkit-translate(-50%, -50%);
    transform: -ms-translate(-50%, -50%);
   }  

Hope will help you too.

I tried function toFixed(2) many times. Every time console shows "toFixed() is not a function".

but how I resolved is By using Math.round()

eg:

if ($(this).attr('name') == 'time') {
    var value = parseFloat($(this).val());
    value = Math.round(value*100)/100; // 10 defines 1 decimals, 100 for 2, 1000 for 3
    alert(value);
}

this thing surely works for me and it might help you guys too...

You can try this query:

Select A.*, (select count(*) from Table1 where A.ID>=ID) as RowNo
from Table1 as A
order by A.ID

r = 13 + 7.*rand(100,1);

Where 100,1 is the size of the desidered vector

int *a[], when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:

int (*aptr)[N]

Where N is a particular positive integer (not a variable).

If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):

template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        (*aptr)[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(&a);
}

You could also take a reference:

template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        arr[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(a);
}

File size by MySQL type:

• TINYBLOB 255 bytes = 0.000255 Mb
• BLOB 65535 bytes = 0.0655 Mb
• MEDIUMBLOB 16777215 bytes = 16.78 Mb
• LONGBLOB 4294967295 bytes = 4294.97 Mb = 4.295 Gb

to use the .replace() method effectively on string without creating a separate list for example take a look at the list username containing string with some white space, we want to replace the white space with an underscore in each of the username string.

usernames = ["Joey Tribbiani", "Monica Geller", "Chandler Bing", "Phoebe Buffay"]

to replace the white spaces in each username consider using the range function in python.

for i in range(len(usernames)):
    usernames[i] = usernames[i].lower().replace(" ", "_")

print(usernames)

Ideally we should do it from either controller or directive as per applicable. Use $anchorScroll, $location as dependency injection.

Then call this two method as

$location.hash('scrollToDivID');
$anchorScroll();

Here scrollToDivID is the id where you want to scroll.

Assumed you want to navigate to a error message div as

<div id='scrollToDivID'>Your Error Message</div>

Note that openpyxl does not have a large toolbox for manipulating and editing images. Xlsxwriter has methods for images, but on the other hand cannot import existing worksheets...

I have found that this works for rows... I'm sure there's a way to do it for columns...

import openpyxl

oxl = openpyxl.load_workbook('File Loction Here')
xl = oxl.['SheetName']

x=0
col = "A"
row = x

while (row <= 100):
    y = str(row)
    cell = col + row
    xl[cell] = x
    row = row + 1
    x = x + 1

I also rarely want to print my google docs, and the breaks annoyed me as well.

I installed the Page Sizer add-on from the add-ons menu within google docs, and made the page really long.

The page settings work globally. So your collaborators will also enjoy a page page-break-free experience in google docs, unlike the style-bot solution.

jScrollPane is a good solution to cross browser scrollbars and degrades nicely.

public static Boolean Add_Tag(int totalsize)
{ List<String> fullst = new ArrayList<String>();
            for(int k=0;k<totalsize;k++)
            {
              fullst.addAll();
            }
}

This works..

var $targetGrid = $("#myGridId");
$(window).resize(function () {
    var jqGridWrapperId = "#gbox_" + $targetGrid.attr('id') //here be dragons, this is     generated by jqGrid.
    $targetGrid.setGridWidth($(jqGridWrapperId).parent().width()); //perhaps add padding calculation here?
});

As of January 2020 and Xcode 11.3.1 -

• Open Xcode
• Open Xcode Preferences (Xcode->Preferences or Cmd-,)
• Click on Accounts
• At the left, click on your developer ID
• At the bottom right, click on Manage Certificates...
• In the lower left corner, click the arrow to the right of the + (plus)
• Select Apple Distribution from the menu

Xcode will automatically create an Apple Distribution certificate, install it in Keychain Access, and update Xcode's signing information

(Note: the single Apple Distribution certificate is now provided instead of the previous iOS Distribution certificate and equivalents.)

Here is a function to get the IP address using a filter for local and LAN IP addresses:

function get_IP_address()
{
    foreach (array('HTTP_CLIENT_IP',

                   'HTTP_X_FORWARDED',
                   'HTTP_X_CLUSTER_CLIENT_IP',
                   'HTTP_FORWARDED_FOR',
                   'HTTP_FORWARDED',
                   'REMOTE_ADDR') as $key){
        if (array_key_exists($key, $_SERVER) === true){
            foreach (explode(',', $_SERVER[$key]) as $IPaddress){
                $IPaddress = trim($IPaddress); // Just to be safe

                if (filter_var($IPaddress,
                               FILTER_VALIDATE_IP,

Try the plyr package:

rbind.fill(a,b,c)

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

There is not one which is really usable.
I discuss some issues in my answer to Is there a php library for email address validation?, it is discussed also in Regexp recognition of email address hard?

In short, don't expect a single, usable regex to do a proper job. And the best regex will validate the syntax, not the validity of an e-mail ([email protected] is correct but it will probably bounce...).

Use ld.charAt(0). It will return the first char of the String.

With ld.substring(0, 1), you can get the first character as String.

At this moment there is a method to do this directly on the request object:

request.setTimeout(timeout, function() {
    request.abort();
});

This is a shortcut method that binds to the socket event and then creates the timeout.

If using underscore or lodash, this is the simplest thing to do:

_.countBy(array);

Such that:

_.countBy([5, 5, 5, 2, 2, 2, 2, 2, 9, 4])
=> Object {2: 5, 4: 1, 5: 3, 9: 1}

As pointed out by others, you can then execute the _.keys() and _.values() functions on the result to get just the unique numbers, and their occurrences, respectively. But in my experience, the original object is much easier to deal with.

return String(new Date('12/12/2002')) === "Invalid Date"

Under Chrome v51 on a Mac, I found the rendering settings by clicking in the upper right corner, choosing More tools > Rendering settings and checking the Emulate media button in the options offered at the bottom of the window.

Thank you to all the other posters that led me to this, and credit to those that provided the answer without the images.

A little late, but if any of you have been going crazy trying to use inline SVG as a background, the escaping suggestions above do not quite work. For one, it does not work in IE, and depending on the content of your SVG the technique will cause trouble in other browsers, like FF.

If you base64 encode the svg (not the entire url, just the svg tag and its contents! ) it works in all browsers. Here is the same jsfiddle example in base64: http://jsfiddle.net/vPA9z/3/

The CSS now looks like this:

body { background-image:

Remember to remove any URL escaping before converting to base64. In other words, the above example showed color='#fcc' converted to color='%23fcc', you should go back to #.

The reason why base64 works better is that it eliminates all the issues with single and double quotes and url escaping

If you are using JS, you can use window.btoa() to produce your base64 svg; and if it doesn't work (it might complain about invalid characters in the string), you can simply use https://www.base64encode.org/.

Example to set a div background:

var mySVG = "<svg xmlns='http://www.w3.org/2000/svg' width='10' height='10'><linearGradient id='gradient'><stop offset='10%' stop-color='#F00'/><stop offset='90%' stop-color='#fcc'/> </linearGradient><rect fill='url(#gradient)' x='0' y='0' width='100%' height='100%'/></svg>";_x000D_
var mySVG64 = window.btoa(mySVG);_x000D_
document.getElementById('myDiv').style.backgroundImage = "url('data:image/svg+xml;base64," + mySVG64 + "')";

html, body, #myDiv {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}

<div id="myDiv"></div>

With JS you can generate SVGs on the fly, even changing its parameters.

One of the better articles on using SVG is here : http://dbushell.com/2013/02/04/a-primer-to-front-end-svg-hacking/

Hope this helps

The class you're looking for already exists. Map.Entry:

public static Entry<Integer,String> myMethod(){
    return new SimpleEntry<>(12, "value");
}

And later:

Entry<Integer,String> valueAndIndex = myMethod();
int index = valueAndIndex.getKey();
String value = valueAndIndex.getValue();

It's just a simple two-field data structure that stores a key and value. If you need to do any special processing, store more than two fields, or have any other fringe case, you should make your own class, but otherwise, Map.Entry is one of the more underutilized Java classes and is perfect for situations like these.

I came here looking for a solution for extended ascii characters, but couldnt find it. The closest I found is bzlm's solution. But that works only for ASCII Code upto 127(obviously you can replace the encoding type in his code, but i think it was a bit complex to understand. Hence, sharing this version). Here's a solution that works for extended ASCII codes i.e. upto 255 which is the ISO 8859-1

It finds and strips out non-ascii characters(greater than 255)

Dim str1 as String= "â, ??î or ôu? n?i?++$-?!??4?od;/?'®;?:?)///1!@#"

Dim extendedAscii As Encoding = Encoding.GetEncoding("ISO-8859-1", 
                                                New EncoderReplacementFallback(String.empty),
                                                New DecoderReplacementFallback())

Dim extendedAsciiBytes() As Byte = extendedAscii.GetBytes(str1)

Dim str2 As String = extendedAscii.GetString(extendedAsciiBytes)

console.WriteLine(str2)
'Output : â, ??î or ôu ni++$-!??4od;/';:)///1!@#$%^yz:

Here's a working fiddle for the code

Replace the encoding as per the requirement, rest should remain the same.

For a quick, clean solution that doesn't require you to name columns, you can use a prepared statement as described here: https://stackoverflow.com/a/23964285/292677

If you need a complex solution so you can do this often, you can use this procedure:

DELIMITER $$

CREATE PROCEDURE `duplicateRows`(_schemaName text, _tableName text, _whereClause text, _omitColumns text)
SQL SECURITY INVOKER
BEGIN
  SELECT IF(TRIM(_omitColumns) <> '', CONCAT('id', ',', TRIM(_omitColumns)), 'id') INTO @omitColumns;

  SELECT GROUP_CONCAT(COLUMN_NAME) FROM information_schema.columns 
  WHERE table_schema = _schemaName AND table_name = _tableName AND FIND_IN_SET(COLUMN_NAME,@omitColumns) = 0 ORDER BY ORDINAL_POSITION INTO @columns;

  SET @sql = CONCAT('INSERT INTO ', _tableName, '(', @columns, ')',
  'SELECT ', @columns, 
  ' FROM ', _schemaName, '.', _tableName, ' ',  _whereClause);

  PREPARE stmt1 FROM @sql;
  EXECUTE stmt1;
END

You can run it with:

CALL duplicateRows('database', 'table', 'WHERE condition = optional', 'omit_columns_optional');

Examples

duplicateRows('acl', 'users', 'WHERE id = 200'); -- will duplicate the row for the user with id 200
duplicateRows('acl', 'users', 'WHERE id = 200', 'created_ts'); -- same as above but will not copy the created_ts column value    
duplicateRows('acl', 'users', 'WHERE id = 200', 'created_ts,updated_ts'); -- same as above but also omits the updated_ts column
duplicateRows('acl', 'users'); -- will duplicate all records in the table

DISCLAIMER: This solution is only for someone who will be repeatedly duplicating rows in many tables, often. It could be dangerous in the hands of a rogue user.

I came up with the following which takes account of rubbish passed in and file_get_contents failing....

function get_lonlat(  $addr  ) {
    try {
            $coordinates = @file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($addr) . '&sensor=true');
            $e=json_decode($coordinates);
            // call to google api failed so has ZERO_RESULTS -- i.e. rubbish address...
            if ( isset($e->status)) { if ( $e->status == 'ZERO_RESULTS' ) {echo '1:'; $err_res=true; } else {echo '2:'; $err_res=false; } } else { echo '3:'; $err_res=false; }
            // $coordinates is false if file_get_contents has failed so create a blank array with Longitude/Latitude.
            if ( $coordinates == false   ||  $err_res ==  true  ) {
                $a = array( 'lat'=>0,'lng'=>0);
                $coordinates  = new stdClass();
                foreach (  $a  as $key => $value)
                {
                    $coordinates->$key = $value;
                }
            } else {
                // call to google ok so just return longitude/latitude.
                $coordinates = $e;

                $coordinates  =  $coordinates->results[0]->geometry->location;
            }

            return $coordinates;
    }
    catch (Exception $e) {
    }

then to get the cords: where $pc is the postcode or address.... $address = get_lonlat( $pc ); $l1 = $address->lat; $l2 = $address->lng;

As per the official documentation of the jquery sortable UI: http://api.jqueryui.com/sortable/#method-toArray

In update event. use:

var sortedIDs = $( ".selector" ).sortable( "toArray" );

and if you alert or console this var (sortedIDs). You'll get your sequence. Please choose as the "Right Answer" if it is a right one.

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

Trivial (but working) solution:

echo -e "---------------------------- [UP]\r$PROC_NAME "

Working with just one selector:

select {
    width: 268px;
    padding: 5px;
    font-size: 16px;
    line-height: 1;
    border: 0;
    border-radius: 5px;
    height: 34px;
    background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right #ddd;
    -webkit-appearance: none;
    background-position-x: 244px;

Kotlin's @Transientannotation also does the trick apparently.

data class Json(
    @field:SerializedName("serialized_field_1") val field1: String,
    @field:SerializedName("serialized_field_2") val field2: String,
    @Transient val field3: String
)

Output:

{"serialized_field_1":"VALUE1","serialized_field_2":"VALUE2"}

To set the use of scientific notation in your entire R session, you can use the scipen option. From the documentation (?options):

‘scipen’: integer.  A penalty to be applied when deciding to print
          numeric values in fixed or exponential notation.  Positive
          values bias towards fixed and negative towards scientific
          notation: fixed notation will be preferred unless it is more
          than ‘scipen’ digits wider.

So in essence this value determines how likely it is that scientific notation will be triggered. So to prevent scientific notation, simply use a large positive value like 999:

options(scipen=999)

Performance wise, it should not make any difference. The explicit join syntax seems cleaner to me as it clearly defines relationships between tables in the from clause and does not clutter up the where clause.

Negative top margins can achieve this effect, but they would need to be customized for each page. For instance, this markup...

<div class="product">
<h2>Greatest Product Ever</h2>
<p class="desc">This paragraph appears in the source code directly after the heading and will appear in the search results.</p>
<p class="sidenote">Note: This information appears in HTML after the product description appearing below.</p>
</div>

...and this CSS...

.product { width: 400px; }
.desc { margin-top: 5em; }
.sidenote { margin-top: -7em; }

...would allow you to pull the second paragraph above the first.

Of course, you'll have to manually tweak your CSS for different description lengths so that the intro paragraph jumps up the appropriate amount, but if you have limited control over the other parts and full control over markup and CSS then this might be an option.

No one seems to be doing it like this:

createEventLinkButton.Attributes.Add("onClick", " if (this.innerHTML == 'Please Wait') { return false; } else {  this.innerHTML='Please Wait'; }");

This seems to be the only way that works.

You could use GROUP_CONCAT aggregated function to get all years into a single column, grouped by id and ordered by rate:

SELECT   id, GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
FROM     yourtable
GROUP BY id

Result:

-----------------------------------------------------------
|  ID | GROUPED_YEAR                                      |
-----------------------------------------------------------
| p01 | 2006,2003,2008,2001,2007,2009,2002,2004,2005,2000 |
| p02 | 2001,2004,2002,2003,2000,2006,2007                |
-----------------------------------------------------------

And then you could use FIND_IN_SET, that returns the position of the first argument inside the second one, eg.

SELECT FIND_IN_SET('2006', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
1

SELECT FIND_IN_SET('2009', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
6

Using a combination of GROUP_CONCAT and FIND_IN_SET, and filtering by the position returned by find_in_set, you could then use this query that returns only the first 5 years for every id:

SELECT
  yourtable.*
FROM
  yourtable INNER JOIN (
    SELECT
      id,
      GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
    FROM
      yourtable
    GROUP BY id) group_max
  ON yourtable.id = group_max.id
     AND FIND_IN_SET(year, grouped_year) BETWEEN 1 AND 5
ORDER BY
  yourtable.id, yourtable.year DESC;

Please see fiddle here.

Please note that if more than one row can have the same rate, you should consider using GROUP_CONCAT(DISTINCT rate ORDER BY rate) on the rate column instead of the year column.

The maximum length of the string returned by GROUP_CONCAT is limited, so this works well if you need to select a few records for every group.

one of the way to execute cmd from java !

public void executeCmd() {
    String anyCommand="your command";
    try {
        Process process = Runtime.getRuntime().exec("cmd /c start cmd.exe /K " + anyCommand);

    } catch (IOException e) {
        e.printStackTrace();
    }
}

Basically, the first model you are using is called as document-based storage. You should have a look at popular NoSQL document-based database like MongoDB and CouchDB. Basically, in document based db's, you store data in json files and then you can query on these json files.

The Second model is the popular relational database structure.

If you want to use relational database like MySql then i would suggest you to only use second model. There is no point in using MySql and storing data as in the first model.

To answer your second question, there is no way to query name like 'foo' if you use first model.

I solved this by adding library to the library console below my project:

• Right click and then add library
• add JAVA DB DRIVER.

My project is working !

I would recommend

Java Puzzlers: Traps, Pitfalls, and Corner Cases Book by Joshua Bloch and Neal Gafter

There is a briefly explanation how to check if number is odd. First try is something similar what @AseemYadav tried:

public static boolean isOdd(int i) {
     return i % 2 == 1;
}

but as was mentioned in book:

when the remainder operation returns a nonzero result, it has the same sign as its left operand

so generally when we have negative odd number then instead of 1 we'll get -1 as result of i%2. So we can use @Camilo solution or just do:

public static boolean isOdd(int i) {
     return i % 2 != 0;
}

but generally the fastest solution is using AND operator like @lucasmo write above:

public static boolean isOdd(int i) {
     return (i & 1) != 0;
}

@Edit It also worth to point Math.floorMod(int x, int y); which deals good with negative the dividend but also can return -1 if the divisor is negative

Just add the line: sql_mode = "NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

inside file: /etc/mysql/mysql.conf.d/mysqld.cnf

then sudo service mysql restart

We can catch all the clicks. The idea is to reset focus on an element outside the iFrame after each click:

    <input type="text" style="position:fixed;top:-1000px;left:-1000px">
    <div id="message"></div>
    <iframe id="iframe" src="//example.com"></iframe>
    <script>
        focus();
        addEventListener('blur', function() {
            if(document.activeElement = document.getElementById('iframe')) {
                message.innerHTML += 'Clicked';
                setTimeout(function () {
                    document.querySelector("input").focus();
                    message.innerHTML += ' - Reset focus,';
                }, 1000);
            }  
        });
    </script>

The default pager is stdout. The stdout has the column limitation, so the output would be wrapped. You could set other tools as pager to format the output. There are two methods. One is to limit the column, the other is to processed it in vim.

The first method:

?  ~  echo $COLUMNS
179

VI shows newlines (LF character, code x0A) by showing the subsequent text on the next line.

Use the -b switch for binary mode. Eg vi -b filename or vim -b filename --.

It will then show CR characters (x0D), which are not normally used in Unix style files, as the characters ^M.

Rather than using aliases, I prefer creating git-XXX scripts so I can source control them more easily (our devs all have a certain source controlled dir on their path for this type of thing).

This script (called git-setpush) will set the config value for remote.origin.push value to something that will only push the current branch:

#!/bin/bash -eu

CURRENT_BRANCH=$(git branch | grep '^\*' | cut -d" " -f2)
NEW_PUSH_REF=HEAD:refs/for/$CURRENT_BRANCH

echo "setting remote.origin.push to $NEW_PUSH_REF"
git config remote.origin.push $NEW_PUSH_REF

note, as we're using Gerrit, it sets the target to refs/for/XXX to push into a review branch. It also assumes origin is your remote name.

Invoke it after checking out a branch with

git checkout your-branch
git setpush

It could obviously be adapted to also do the checkout, but I like scripts to do one thing and do it well

Small tip for you. Microsoft frequently has 'launch parties' or 'launch events' in which they frequently distribute licensed, not for resale copies, of that product. I've gotten the last two versions of VS (2005 and 2008) by attending my local .NET user group chapter during those days.

It looks like Microsoft invaded brains of all other respondents and made them write as complicated solutions as possible. Here is the simplest way without any additional functions/declare statements:

SELECT geography::Point(LATITUDE_1, LONGITUDE_1, 4326).STDistance(geography::Point(LATITUDE_2, LONGITUDE_2, 4326))

Simply substitute your data instead of LATITUDE_1, LONGITUDE_1, LATITUDE_2, LONGITUDE_2 e.g.:

SELECT geography::Point(53.429108, -2.500953, 4326).STDistance(geography::Point(c.Latitude, c.Longitude, 4326))
from coordinates c

Use the following

Make sure you don't put a space between the semi-colon and the new folder location that you are adding to the path.

For example it should look like...

{last path entry};C:\Python27;C:\Python27\Scripts;

...not...

{last path entry}; C:\Python27; C:\Python27\Scripts;

I would like to mention a PRETTY COOL feature that has been included since iOS 10, which is:

For now, UIRefreshControl is directly supported in each of UICollectionView, UITableView and UIScrollView!

Each one of these views have refreshControl instance property, which means that there is no longer a need to add it as a subview in your scroll view, all you have to do is:

@IBOutlet weak var collectionView: UICollectionView!

override func viewDidLoad() {
    super.viewDidLoad()

    let refreshControl = UIRefreshControl()
    refreshControl.addTarget(self, action: #selector(doSomething), for: .valueChanged)

    // this is the replacement of implementing: "collectionView.addSubview(refreshControl)"
    collectionView.refreshControl = refreshControl
}

func doSomething(refreshControl: UIRefreshControl) {
    print("Hello World!")

    // somewhere in your code you might need to call:
    refreshControl.endRefreshing()
}

Personally, I find it more natural to treat it as a property for scroll view more than add it as a subview, especially because the only appropriate view to be as a superview for a UIRefreshControl is a scrollview, i.e the functionality of using UIRefreshControl is only useful when working with a scroll view; That's why this approach should be more obvious to setup the refresh control view.

However, you still have the option of using the addSubview based on the iOS version:

if #available(iOS 10.0, *) {
  collectionView.refreshControl = refreshControl
} else {
  collectionView.addSubview(refreshControl)
}

If you want to analyze a file uploaded by the user, the Flask quickstart shows how to get files from users and access them. Get the file from request.files and pass it to the summary function.

from flask import request, jsonify
from werkzeug import secure_filename

@app.route('/summary', methods=['GET', 'POST'])
def summary():
    if request.method == 'POST':
        csv = request.files['data']
        return jsonify(
            summary=make_summary(csv),
            csv_name=secure_filename(csv.filename)
        )

    return render_template('submit_data.html')

Replace the 'data' key for request.files with the name of the file input in your HTML form.

I spent a lot of time to use SerialPort class and has concluded to use SerialPort.BaseStream class instead. You can see source code: SerialPort-source and SerialPort.BaseStream-source for deep understanding. I created and use code that shown below.

• The core function public int Recv(byte[] buffer, int maxLen) has name and works like "well known" socket's recv().

• It means that

  • in one hand it has timeout for no any data and throws TimeoutException.
  • In other hand, when any data has received,
    • it receives data either until maxLen bytes
    • or short timeout (theoretical 6 ms) in UART data flow

.

public class Uart : SerialPort

    {
        private int _receiveTimeout;

        public int ReceiveTimeout { get => _receiveTimeout; set => _receiveTimeout = value; }

        static private string ComPortName = "";

        /// <summary>
        /// It builds PortName using ComPortNum parameter and opens SerialPort.
        /// </summary>
        /// <param name="ComPortNum"></param>
        public Uart(int ComPortNum) : base()
        {
            base.BaudRate = 115200; // default value           
            _receiveTimeout = 2000;
            ComPortName = "COM" + ComPortNum;

            try
            {
                base.PortName = ComPortName;
                base.Open();
            }
            catch (UnauthorizedAccessException ex)
            {

            int TimeOutSpan = 2;
            // counts delay in TimeOutSpan-s after end of data to break receive
            int EndOfDataCnt;

            int totalReceived = 0;

            BaseStream.ReadTimeout = TimeOutSpan;
            //causes (2+1)*TimeOutSpan delay after end of data in UART stream
            EndOfDataCnt = 2;
            while (_tickCount < TimeOutCnt && EndOfDataCnt > 0)
            {

                    justReceived = 0; 
                    justReceived = base.BaseStream.Read(buffer, totalReceived, maxLen - totalReceived);
                    totalReceived += justReceived;

                    if (totalReceived >= maxLen)
                        break;
                }
                catch (TimeoutException)
                {

                    totalReceived = -1;
                    base.Close();
                    Console.WriteLine("Recv exception: " + ex);
                    break;
                }

            } //while
            if (totalReceived == 0)
            {              
                throw new TimeoutException();
            }
            else
            {               
                return totalReceived;
            }
        } // Recv()            
    } // Uart

You need something like:

    URL resource = this.getClass().getResource("/path/to/resource.res");
    File is = null;
    try {
        is = new File(resource.toURI());
    } catch (URISyntaxException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    try {
        FileInputStream input = new FileInputStream(is);
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

But it will work only within your IDE, not in runnable JAR. I had same problem explained here.

If you already have the jquery object in a variable, you can also just treat it as a normal indexed array, without the use of jquery:

var all_rows = $("tr");
for(var i=0; i < all_rows.length; i++){
   var row = all_rows[i];
   //additionally, you can use it again in a jquery selector
   $(row).css("background-color","black");
}

Although the above example is not useful in any way, it is representing how you can treat objects created by jquery as indexed arrays.

NOVEMBER 2018, have tried everything above with no success.

Below is the solution that worked finally. Unfortunately it's not using SSL, but it works!!!

var fromAddress = new MailAddress([email protected], "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");

const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
{
    Host = "aspmx.l.google.com",
    Port = 25,
    EnableSsl = false
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

A script I wrote for my GitBash. Accomplishes the following:

• By default pulls from origin for all branches that are setup to track origin, allows you to specify a different remote if desired.
• If your current branch is in a dirty state then it stashes your changes and will attempt to restore these changes at the end.
• For each local branch that is set up to track a remote branch will:
  • git checkout branch
  • git pull origin
• Finally, will return you to your original branch and restore state.

** I use this but have not tested thoroughly, use at own risk. See an example of this script in a .bash_alias file here.

    # Do a pull on all branches that are tracking a remote branches, will from origin by default.
    # If current branch is dirty, will stash changes and reply after pull.
    # Usage: pullall [remoteName]
    alias pullall=pullAll
    function pullAll (){
     # if -h then show help
     if [[ $1 == '-h' ]]
    then
      echo "Description: Pulls new changes from upstream on all branches that are tracking remotes."
      echo 
      echo "Usage: "
      echo "- Default: pullall"
      echo "- Specify upstream to pull from: pullall [upstreamName]"
      echo "- Help: pull-all -h"
    else

     # default remote to origin
     remote="origin"
     if [ $1 != "" ]
     then
       remote=$1
     fi

     # list all branches that are tracking remote
     # git branch -vv : list branches with their upstreams
     # grep origin : keep only items that have upstream of origin
     # sed "s/^.."... : remove leading *
     # sed "s/^"..... : remove leading white spaces
     # cut -d" "..... : cut on spaces, take first item
     # cut -d splits on space, -f1 grabs first item
     branches=($(git branch -vv | grep $remote | sed "s/^[ *]*//" | sed "s/^[ /t]*//" | cut -d" " -f1))

     # get starting branch name
     startingBranch=$(git rev-parse --abbrev-ref HEAD)

     # get starting stash size
     startingStashSize=$(git stash list | wc -l)

     echo "Saving starting branch state: $startingBranch"
     git stash

     # get the new stash size
     newStashSize=$(git stash list | wc -l)

     # for each branch in the array of remote tracking branches
     for branch in ${branches[*]}
     do
       echo "Switching to $branch"
       git checkout $branch

       echo "Pulling $remote"
       git pull $remote

     done

     echo "Switching back to $startingBranch"
     git checkout $startingBranch

     # compare before and after stash size to see if anything was stashed
     if [ "$startingStashSize" -lt "$newStashSize" ]
     then
       echo "Restoring branch state"
       git stash pop
     fi
    fi
    }

You can change your UI culture to anything you want, but you should change the number separator like this:

CultureInfo info = new CultureInfo("fa-IR");
info.NumberFormat.NumberDecimalSeparator = ".";
Thread.CurrentThread.CurrentCulture = info;
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

With this, your strings converts like this: "12.49" instead of "12,49" or "12/49"

If you want to use a class:

from datetime import datetime,timedelta

class MyThread(): 

    def __init__(self, name, timeLimit):        
        self.name = name
        self.timeLimit = timeLimit
    def run(self): 
        # get the start time
        startTime = datetime.now()
    
        while True:
           # stop if the time limit is reached :
           if((datetime.now()-startTime)>self.timeLimit):
               break
           print('A')

mt = MyThread('aThread',timedelta(microseconds=20000))
mt.run()

You can get the instance of the controller from the FXMLLoader after initialization via getController(), but you need to instantiate an FXMLLoader instead of using the static methods then.

I'd pass the stage after calling load() directly to the controller afterwards:

FXMLLoader loader = new FXMLLoader(getClass().getResource("MyGui.fxml"));
Parent root = (Parent)loader.load();
MyController controller = (MyController)loader.getController();
controller.setStageAndSetupListeners(stage); // or what you want to do

If the order of the execution is not important and you need both some javascript AND some codebehind to be fired on an asp element, heres what you can do.

What you can take away from my example: I have a div covering the ASP control that I want both javascript and codebehind to be ran from. The div's onClick method AND the calendar's OnSelectionChanged event both get fired this way.

In this example, i am using an ASP Calendar control, and im controlling it from both javascript and codebehind:

Front end code:

        <div onclick="showHideModal();">
            <asp:Calendar 
                OnSelectionChanged="DatepickerDateChange" ID="DatepickerCalendar" runat="server" 
                BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" 
                Font-Size="8pt" ShowGridLines="true" BackColor="#B8C9E1" BorderColor="#003E51" Width="100%"> 
                <OtherMonthDayStyle ForeColor="#6C5D34"> </OtherMonthDayStyle> 
                <DayHeaderStyle  ForeColor="black" BackColor="#D19000"> </DayHeaderStyle>
                <TitleStyle BackColor="#B8C9E1" ForeColor="Black"> </TitleStyle> 
                <DayStyle BackColor="White"> </DayStyle> 
                <SelectedDayStyle BackColor="#003E51" Font-Bold="True"> </SelectedDayStyle> 
            </asp:Calendar>
        </div>

Codebehind:

        protected void DatepickerDateChange(object sender, EventArgs e)
        {
            if (toFromPicked.Value == "MainContent_fromDate")
            {
                fromDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
            else
            {
                toDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
        }

If you are using homebrew and homebrew services, you can probably just do:

brew services stop postgresql
brew upgrade postgresql
brew postgresql-upgrade-database
brew services start postgresql

I think this might not work completely if you are using advanced postgres features, but it worked perfectly for me.

You can use a transformation for your data frame:

df = pd.DataFrame(my_data condition)

transforming True/False in 1/0

df = df*1

This works perfectly for me:

import subprocess
try:
    #prints results and merges stdout and std
    result = subprocess.check_output("echo %USERNAME%", stderr=subprocess.STDOUT, shell=True)
    print result
    #causes error and merges stdout and stderr
    result = subprocess.check_output("copy testfds", stderr=subprocess.STDOUT, shell=True)
except subprocess.CalledProcessError, ex: # error code <> 0 
    print "--------error------"
    print ex.cmd
    print ex.message
    print ex.returncode
    print ex.output # contains stdout and stderr together 

It's the '+' operator at the beginning of the line that trips things up (not just that you are using two '+' operators consecutively). The '+' operator can be used at the end of lines, but not at the beginning.

This works:

ggplot(combined.data, aes(x = region, y = expression, fill = species)) +
geom_boxplot() 

The does not:

ggplot(combined.data, aes(x = region, y = expression, fill = species))
+ geom_boxplot() 

*Error in + geom_boxplot():
invalid argument to unary operator*

You also can't use two '+' operators, which in this case you've done. But to fix this, you'll have to selectively remove those at the beginning of lines.

If you start having to mentally count off the parameters in the signature and match them to the call, then it is time to refactor!

We can migrate the logic to various methods foe Java 7, Java 8 and Java 9:

public static List<Date> getDatesRangeJava7(Date startDate, Date endDate) {
    List<Date> datesInRange = new ArrayList<>();
    Calendar startCalendar = new GregorianCalendar();
    startCalendar.setTime(startDate);
    Calendar endCalendar = new GregorianCalendar();
    endCalendar.setTime(endDate);
    while (startCalendar.before(endCalendar)) {
        Date result = startCalendar.getTime();
        datesInRange.add(result);
        startCalendar.add(Calendar.DATE, 1);
    }
    return datesInRange;
}

public static List<LocalDate> getDatesRangeJava8(LocalDate startDate, LocalDate endDate) {
    int numOfDays = (int) ChronoUnit.DAYS.between(startDate, endDate);
    return IntStream.range(0, numOfDays)
            .mapToObj(startDate::plusDays)
            .collect(Collectors.toList());
}

public static List<LocalDate> getDatesRangeJava9(LocalDate startDate, LocalDate endDate) {
    return startDate.datesUntil(endDate).collect(Collectors.toList());
}

Then we can invoke these methods as:

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date startDate = formatter.parse("2010-12-20");
Date endDate = formatter.parse("2010-12-26");
List<Date> dateRangeList = getDatesRangeJava7(startDate, endDate);
System.out.println(dateRangeList);

LocalDate startLocalDate = startDate.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
LocalDate endLocalDate = endDate.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
List<LocalDate> dateRangeList8 = getDatesRangeJava8(startLocalDate, endLocalDate);
System.out.println(dateRangeList8);
List<LocalDate> dateRangeList9 = getDatesRangeJava8(startLocalDate, endLocalDate);
System.out.println(dateRangeList9);

The output would be:

[Mon Dec 20 00:00:00 IST 2010, Tue Dec 21 00:00:00 IST 2010, Wed Dec 22 00:00:00 IST 2010, Thu Dec 23 00:00:00 IST 2010, Fri Dec 24 00:00:00 IST 2010, Sat Dec 25 00:00:00 IST 2010]

So the doctors here that are saying "You say that hurts? Then don't do that!" are probably right. But if you really want to, here's one way of passing arguments to a unittest test:

import sys
import unittest

class MyTest(unittest.TestCase):
    USERNAME = "jemima"
    PASSWORD = "password"

    def test_logins_or_something(self):
        print('username : {}'.format(self.USERNAME))
        print('password : {}'.format(self.PASSWORD))


if __name__ == "__main__":
    if len(sys.argv) > 1:
        MyTest.USERNAME = sys.argv.pop()
        MyTest.PASSWORD = sys.argv.pop()
    unittest.main()

that will let you run with:

python mytests.py ausername apassword

You need the argv.pops so your command line params don't mess with unittest's own...

[update] The other thing you might want to look into is using environment variables:

import os
import unittest

class MyTest(unittest.TestCase):
    USERNAME = "jemima"
    PASSWORD = "password"

    def test_logins_or_something(self):
        print('username : {}'.format(self.USERNAME))
        print('password : {}'.format(self.PASSWORD))


if __name__ == "__main__":
    MyTest.USERNAME = os.environ.get('TEST_USERNAME', MyTest.USERNAME)            
    MyTest.PASSWORD = os.environ.get('TEST_PASSWORD', MyTest.PASSWORD)
    unittest.main()

That will let you run with:

TEST_USERNAME=ausername TEST_PASSWORD=apassword python mytests.py

and it has the advantage that you're not messing with unittest's own argument parsing. downside is it won't work quite like that on Windows...

Three basic rules:

1. Set pointer to NULL after free
2. Check for NULL before freeing.
3. Initialise pointer to NULL in the start.

Combination of these three works quite well.

In addition to Lorenzo Marcon's answer:

Using preg_replace to select everything except style attribute:

$html = preg_replace('/(<p.+?)style=".+?"(>.+?)/i', "$1$2", $html);

The following code exhibits various examples related to getting/putting of values from input/select fields using JavaScript.

Working Javascript & jQuery Demo

 <select id="Ultra" onchange="run()">  <!--Call run() function-->
     <option value="0">Select</option>
     <option value="8">text1</option>
     <option value="5">text2</option>
     <option value="4">text3</option>
</select><br><br>
TextBox1<br>
<input type="text" id="srt" placeholder="get value on option select"><br>
TextBox2<br>
<input type="text" id="rtt"  placeholder="Write Something !" onkeyup="up()">

The following script is getting the value of the selected option and putting it in text box 1

<script>
    function run() {
        document.getElementById("srt").value = document.getElementById("Ultra").value;
    }
</script>

The following script is getting a value from a text box 2 and alerting with its value

<script>
    function up() {
        //if (document.getElementById("srt").value != "") {
            var dop = document.getElementById("srt").value;
        //}
        alert(dop);
    }
</script>

The following script is calling a function from a function

<script>
    function up() {
        var dop = document.getElementById("srt").value;
        pop(dop); // Calling function pop
    }

    function pop(val) {
        alert(val);
    }?
</script>

O(1) does not necessarily mean "quickly". It means that the time it takes is constant, and not based on the size of the input to the function. Constant could be fast or slow. O(n) means that the time the function takes will change in direct proportion to the size of the input to the function, denoted by n. Again, it could be fast or slow, but it will get slower as the size of n increases.

• the simplest way to do that is using encoding/json package

just for example:

package main
import (
    "fmt"
    "encoding/json"
)

type MyAddress struct {
    House string
    School string
}
type Student struct {
    Id int64
    Name string
    Scores float32
    Address MyAddress
    Labels []string
}

func Test() {

    dict := make(map[string]interface{})
    dict["id"] = 201902181425       // int
    dict["name"] = "jackytse"       // string
    dict["scores"] = 123.456        // float
    dict["address"] = map[string]string{"house":"my house", "school":"my school"}   // map
    dict["labels"] = []string{"aries", "warmhearted", "frank"}      // slice

    jsonbody, err := json.Marshal(dict)
    if err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    student := Student{}
    if err := json.Unmarshal(jsonbody, &student); err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    fmt.Printf("%#v\n", student)
}

func main() {
    Test()
}

For Older browsers, you need to add this line on top of HTML doc

As Umesh Patil answer have comment say that there is problem. I try to edit answer and get reject. And get suggest to post new answer. This code should solve problem they have (Shashi Roy, Gaven, John Higgins).

<html> 
<head>  
<script type="text/javascript">
function CheckColors(val){
 var element=document.getElementById('othercolor');
 if(val=='others')
   element.style.display='block';
 else  
   element.style.display='none';
}

</script> 
</head>
<body>
  <select name="color" onchange='CheckColors(this.value);'> 
    <option>pick a color</option>  
    <option value="red">RED</option>
    <option value="blue">BLUE</option>
    <option value="others">others</option>
  </select>
<input type="text" name="othercolor" id="othercolor" style='display:none;'/>
</body>
</html>

I like doing something like this:

Message::select('*')
->from(DB::raw("( SELECT * FROM `messages`
                  WHERE `to_id` = ".Auth::id()." AND `isseen` = 0
                  GROUP BY `from_id` asc) as `sub`"))
->count();

It's not very elegant, but it's simple.

In my case with Android Studio 1.1.0 path was this

/Users/wzbozon/Library/Android/sdk/platform-tools

Add the following to ~/.bash_profile

export PATH=~/Library/Android/sdk/tools:$PATH
export PATH=~/Library/Android/sdk/platform-tools:$PATH

Two problems:

1. Your function does not return anything; a function that does not explicitly return anything returns None (which is falsy)

2. True is always True - you are not checking the result of your function

.

def check(fname, txt):
    with open(fname) as dataf:
        return any(txt in line for line in dataf)

if check('example.txt', 'blabla'):
    print "true"
else:
    print "false"

Use this:

    public void ShowAllPostBackData()
    {
        if (IsPostBack)
        {
            string[] keys = Request.Form.AllKeys;
            Literal ctlAllPostbackData = new Literal();
            ctlAllPostbackData.Text = "<div class='well well-lg' style='border:1px solid black;z-index:99999;position:absolute;'><h3>All postback data:</h3><br />";
            for (int i = 0; i < keys.Length; i++)
            {
                ctlAllPostbackData.Text += "<b>" + keys[i] + "</b>: " + Request[keys[i]] + "<br />";
            }
            ctlAllPostbackData.Text += "</div>";
            this.Controls.Add(ctlAllPostbackData);
        }
    }

I could be wrong, but I believe since you are inheriting from foo, you have to call a base constructor. Since you explicitly defined the foo constructor to require (int, int) now you need to pass that up the chain.

public bar(int a, int b) : base(a, b)
{
     c = a * b;
}

This will initialize foo's variables first and then you can use them in bar. Also, to avoid confusion I would recommend not naming parameters the exact same as the instance variables. Try p_a or something instead, so you won't accidentally be handling the wrong variable.

A string is one string, a string[] is a string array. It means it's a variable with multiple strings in it.

Although you can convert a string to a string[] (create a string array with one element in it), it's probably a sign that you're trying to do something which you shouldn't do.

add float: left property to the image.

#rb-menu-com li .submenu div img {
    border:1px solid #fff;
    float:left;
}

You can use statement body in lamba expression for IEnumerable collections. try this one:

Obj[] myArray = objects.AsEnumerable().Select(o =>
{
    var someLocalVar = o.someVar;

    return new Obj() 
    { 
        Var1 = someLocalVar,
        Var2 = o.var2 
    };
}).ToArray();

Notice:
Think carefully when using this method, because this way, you will have all query result in memory, that may have unwanted side effects on the rest of your code.

For some databases, you can just explicitly insert a NULL into the auto_increment column:

INSERT INTO table_name VALUES (NULL, 'my name', 'my group')

The following page provides a relatively good guide that requires few corrections : https://cv-tricks.com/how-to/installation-of-opencv-4-1-0-in-windows-10-from-source/

On step 8, when you are choosing generator for the project (tool used for building), don't forget to specify x64 in the second field if you need it. If you don't, you will get LNK1112 error, which is a linker error caused if one module is created with the x64 compiler, and another module is created with the x86 compiler.

Next, when choosing flags in step 9, don't forget to tick the "OPENCV_ENABLE_NONFREE", and set the path for flag "OPENCV_EXTRA_MODULES_PATH" flag. The path must be set to "modules" folder in opencv-contrib-python.

So you need both opencv, and opencv-contrib-python in order to use SIFT and SURF.

Not sure where you add the json but if i do it like this with angular it works without the requestBody: angluar:

    const params: HttpParams = new HttpParams().set('str1','val1').set('str2', ;val2;);
    return this.http.post<any>( this.urlMatch,  params , { observe: 'response' } );

java:

@PostMapping(URL_MATCH)
public ResponseEntity<Void> match(Long str1, Long str2) {
  log.debug("found: {} and {}", str1, str2);
}

The delimiter can be a regular expression.

awk -F'[/=]' '{print $3 "\t" $5 "\t" $8}' file

Produces:

tc0001   tomcat7.1    demo.example.com  
tc0001   tomcat7.2    quest.example.com  
tc0001   tomcat7.5    www.example.com

Config is written to .npmrc files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list will allways list the active config.

1. npm builtin config file (/path/to/npm/npmrc)
2. global config file ($PREFIX/etc/npmrc)
3. per-user config file ($HOME/.npmrc)
4. per-project config file (/path/to/my/project/.npmrc)

Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.

getEventListeners(document.querySelector('your-element-selector'));

Detect most browsers with this:

var getBrowser = function(){
  var navigatorObj = navigator.appName,
      userAgentObj = navigator.userAgent,
      matchVersion;
  var match = userAgentObj.match(/(opera|chrome|safari|firefox|msie|trident)\/?\s*(\.?\d+(\.\d+)*)/i);
  if( match && (matchVersion = userAgentObj.match(/version\/([\.\d]+)/i)) !== null) match[2] = matchVersion[1];
  //mobile
  if (navigator.userAgent.match(/iPhone|Android|webOS|iPad/i)) {
    return match ? [match[1], match[2], mobile] : [navigatorObj, navigator.appVersion, mobile];
  }
  // web browser
  return match ? [match[1], match[2]] : [navigatorObj, navigator.appVersion, '-?'];
};

Don't use str() method directly in html instead use with y=x|string()

<div class="row">
    {% for x in range(photo_upload_count) %}
        {% with y=x|string() %}

    <div col-md-4 >
        <div class="col-md-12">
            <div class="card card-primary "  style="border:1px solid #000">
                <div class="card-body">
                    {% if data['profile_photo']!= None: %}
                        <img class="profile-user-img img-responsive" src="{{ data['photo_'+y] }}" width="200px" alt="User profile picture">
                    {% else: %}
                        <img class="profile-user-img img-responsive" src="static/img/user.png" width="200px" alt="User profile picture">
                    {% endif %}
                </div>
                <div class="card-footer text-center">
                    <a href="{{value}}edit_photo/{{ 'photo_'+y }}" class="btn btn-primary">Edit</a>
                </div>
            </div>
        </div>
    </div>
    {% endwith %}
    {% endfor %}
</div>

This is pretty straightforward using the File class.

if(File.Exists(@"C:\test.txt"))
{
    File.Delete(@"C:\test.txt");
}

I was facing the same problem, and I found the solution. There are issues in allocation of MaxPermSize. If you try to allocate more than your machine's free space then it gives this error in my issue. So try to reduce MaxPermSize.

I think it will help you to sort out your issue.

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

For apache look up SymLink or you can solve via the OS with Symbolic Links or on linux set up a library link/etc

My answer is one method specifically to windows 10.

So my method involves mapping a network drive to U:/ (e.g. I use G:/ for Google Drive)

open cmd and type hostname (example result: LAPTOP-G666P000, you could use your ip instead, but using a static hostname for identifying yourself makes more sense if your network stops)

Press Windows_key + E > right click 'This PC' > press N (It's Map Network drive, NOT add a network location)

If you are right clicking the shortcut on the desktop you need to press N then enter

Fill out U: or G: or Z: or whatever you want Example Address: \\LAPTOP-G666P000\c$\Users\username\

Then you can use <a href="file:///u:/2ndFile.html"><button type="submit">Local file</button> like in your question

related: You can also use this method for FTPs, and setup multiple drives for different relative paths on that same network.

related2: I have used http://localhost/c$ etc before on some WAMP/apache servers too before, you can use .htaccess for control/security but I recommend to not do so on a live/production machine -- or any other symlink documentroot example you can google

Your second question is easy, GET has a size limitation of 1-2 kilobytes on both the server and browser side, so any kind of larger amounts of data you'd have to send through POST.

I also had the same problem, I searched for the answers many places. I got many similar answers to change the number of process/service handlers. But I thought, what if I forgot to reset it back?

Then I tried using Thread.sleep() method after each of my connection.close();.

I don't know how, but it's working at least for me.

If any one wants to try it out and figure out how it's working then please go ahead. I would also like to know it as I am a beginner in programming world.

Submitting Form Without Reloading The Page And Get Result Of Submitted Data In The Same Page

1.) IFRAME

When the form is submitted, The action will be executed and target the specific iframe to reload.

index.php

<iframe name="content" style="">
</iframe>
<form action="iframe_content.php" method="post" target="content">
<input type="text" name="Name" value="">
<input type="submit" name="Submit" value="Submit">
</form>

iframe_content.php

<?php
if (isset($_POST['Submit'])){
$Name = $_POST['Name'];
echo $Name;
}
?>

2.) AJAX

Index.php:

   <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/core.js">

You need to set the flags after the project command in your CMakeLists.txt.

Also, if you're calling include(${QT_USE_FILE}) or add_definitions(${QT_DEFINITIONS}), you should include these set commands after the Qt ones since these would append further flags. If that is the case, you maybe just want to append your flags to the Qt ones, so change to e.g.

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O0 -ggdb")

Just had to do this alter user defined table type in one of my projects. Here are the steps I employed:

1. Find all the SP using the user defined table type.
2. Save a create script for all the SP(s) found.
3. Drop the SP(s).
4. Save a create script for the user defined table you wish to alter. 4.5 Add the additional column or changes you need to the user defined table type.
5. Drop the user defined table type.
6. Run the create script for the user defined table type.
7. Run the create script for the SP(s).
8. Then start modifying the SP(s) accordingly.

You could use KEY unique key (combination of the data) that changes with props, and that component will be rerendered with updated props.

Use option bty = "n" in legend to remove the box around the legend. For example:

legend(1, 5,
       "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
       bty = "n")

Turning the firewall off resolved it for me.

VB Code:

Dim ListItem1 As New ListItem()
ListItem1.Text = "put anything here"
ListItem1.Value = "0"
drpTag.DataBind()
drpTag.Items.Insert(0, ListItem1)

View:

<asp:CompareValidator ID="CompareValidator1" runat="server" ErrorMessage="CompareValidator" ControlToValidate="drpTag" 
  ValueToCompare="0">
</asp:CompareValidator>

Usually, you do not want to add anything to a Request object, it's better to use collection and put() helper:

function store(Request $request) 
{
    // some additional logic or checking
    User::create(array_merge($request->all(), ['index' => 'value']));
}

Or you could union arrays:

User::create($request->all() + ['index' => 'value']);

But, if you really want to add something to a Request object, do this:

$request->request->add(['variable' => 'value']); //add request

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

If you want to extract the hours, minutes and seconds, try this:

String inputDate = "12:00:00";
String[] split = inputDate.split(":");
int hours = Integer.valueOf(split[0]);
int minutes = Integer.valueOf(split[1]);
int seconds = Integer.valueOf(split[2]);

string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) {
    connection.Open();
    bulkCopy.DestinationTableName = "TableName";
    try {
        bulkCopy.WriteToServer(dataTableName);
    } catch (Exception e) {
        Console.Write(e.Message);
    }
}

Please note that the structure of the database table and the table name should be the same or it will throw an exception.

The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.

It looks like you want the return keyword

def check_ping():
    hostname = "taylor"
    response = os.system("ping -c 1 " + hostname)
    # and then check the response...
    if response == 0:
        pingstatus = "Network Active"
    else:
        pingstatus = "Network Error"

    return pingstatus

You need to capture/'receive' the return value of the function(pingstatus) in a variable with something like:

pingstatus = check_ping()

NOTE: ping -c is for Linux, for Windows use ping -n

Some info on python functions:

It's probably worth going through a good introductory tutorial to Python, which will cover all the fundamentals. I recommend investigating Udacity.com and codeacademy.com

There is no tuple type in Go, and you are correct, the multiple values returned by functions do not represent a first-class object.

Nick's answer shows how you can do something similar that handles arbitrary types using interface{}. (I might have used an array rather than a struct to make it indexable like a tuple, but the key idea is the interface{} type)

My other answer shows how you can do something similar that avoids creating a type using anonymous structs.

These techniques have some properties of tuples, but no, they are not tuples.

Isn't this just a question of factoring the number - determining all the factors of the number? You can then decide whether you need all combinations of one or more factors.

So, one possible algorithm would be:

factor(N)
    divisor = first_prime
    list_of_factors = { 1 }
    while (N > 1)
        while (N % divisor == 0)
            add divisor to list_of_factors
            N /= divisor
        divisor = next_prime
    return list_of_factors

It is then up to you to combine the factors to determine the rest of the answer.

update based on Ordering by the order of values in a SQL IN() clause

Solution:

DECLARE @counter int
SET @counter = 0

;WITH q  AS
        (
select * from Products WHERE ID in (SELECT TOP (10) ID FROM Products WHERE  ID IN( 3,2,1) 
ORDER BY ID DESC)
        )
update q set Display= @counter, @counter = @counter + 1

This updates based on descending 3,2,1

Hope helps someone.

DiffUtil can the best choice for updating the data in the RecyclerView Adapter which you can find in the android framework. DiffUtil is a utility class that can calculate the difference between two lists and output a list of update operations that converts the first list into the second one.

Most of the time our list changes completely and we set new list to RecyclerView Adapter. And we call notifyDataSetChanged to update adapter. NotifyDataSetChanged is costly. DiffUtil class solves that problem now. It does its job perfectly!

JOptionPane.showInternalInputDialog probably does what you want. If not, it would be helpful to understand what it is missing.

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

I find it easier to remember to just read it and then write it.

For example:

with open('file') as f:
    data = f.read()
with open('file', 'w') as f:
    f.write('hello')

In Winform App(C#):

static string strFilesLoc = Path.GetFullPath(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), @"..\..\")) + "Resources\\";
    public static string[] GetFontFamily()
            {
                var result = File.ReadAllText(strFilesLoc + "FontFamily.txt").Trim();
                string[] items = result.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
                return items;
            }

In-text file(FontFamily.txt):

.cpp is the recommended extension for C++ as far as I know. Some people even recommend using .hpp for C++ headers, just to differentiate from C.

Although the compiler doesn't care what you do, it's personal preference.

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")
