This is the best you can do, as far as I know...

var keys = [];
for (var k in h)keys.push(k);

The hostname regex of smink does not observe the limitation on the length of individual labels within a hostname. Each label within a valid hostname may be no more than 63 octets long.

ValidHostnameRegex="^([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])\
(\.([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9]))*$"

Note that the backslash at the end of the first line (above) is Unix shell syntax for splitting the long line. It's not a part of the regular expression itself.

Here's just the regular expression alone on a single line:

^([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])(\.([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9]))*$

You should also check separately that the total length of the hostname must not exceed 255 characters. For more information, please consult RFC-952 and RFC-1123.

Looking at the error stack trace, it seems your timer is still active. Try to cancel the timer upon closing the form (i.e. in the form's OnClose() method). This looks like the cleanest solution.

Creating ad-hoc distribution profiles

The instructions that Apple provides are here, but here is how I created a general provisioning profile that will work with multiple apps, and added a beta tester.

My setup:

• Xcode 3.2.1
• iPhone SDK 3.1.3

Before you get started, make sure that..

• You can run the app on your own iPhone through Xcode.

Step A: Add devices to the Provisioning Portal

1. Send an email to each beta tester with the following message:

   To get my app on onto your iPhone I need some information about your phone. Guess what, there is an app for that!

   Click on the below link and install and then run the app.

   http://itunes.apple.com/app/ad-hoc-helper/id285691333?mt=8

   This app will create an email. Please send it to me.

2. Collect all the UDIDs from your testers.

3. Go to the Provisioning Portal.

4. Go to the section Devices.

5. Click on the button Add Devices and add the devices previously collected.

Step B: Create a new provisioning profile

1. Start the Mac OS utility program Keychain Access.

2. In its main menu, select Keychain Access / Certificate Assistant / Request a Certificate From a Certificate Authority...

3. The dialog that pops up should aready have your email and name it it.

4. Select the radio button Saved to disk and Continue.

5. Save the file to disk.

6. Go back to the Provisioning Portal.

7. Go to the section Certificates.

8. Go to the tab Distribution.

9. Click the button Request Certificate.

10. Upload the file you created with Keychain Access: CertificateSigningRequest.certSigningRequest.

11. Click the button Aprove.

12. Refresh your browser until the status reads Issued.

13. Click the Download button and save the file distribution_identify.cer.

14. Doubleclick the file to add it to the Keychain.

15. Backup the certificate by selecting its private key and the File / Export Items....

16. Go back to the Provisioning Portal again.

17. Go to the section Provisioning.

18. Go to the tab Distribution.

19. Click the button New Profile.

20. Select the radio button Ad hoc.

21. Enter a profile name, I named mine Evertsson Common Ad Hoc.

22. Select the app id. I have a common app id to use for multiple apps: Evertsson Common.

23. Select the devices, in my case my own and my tester's.

24. Submit.

25. Refresh the browser until the status field reads Active.

26. Click the button Download and save the file to disk.

27. Doubleclick the file to add it to Xcode.

Step C: Build the app for distribution

1. Open your project in Xcode.

2. Open the Project Info pane: In Groups & Files select the topmost item and press Cmd+I.

3. Go to the tab Configuration.

4. Select the configuration Release.

5. Click the button Duplicate and name it Distribution.

6. Close the Project Info pane.

7. Open the Target Info pane: In Groups & Files expand Targets, select your target and press Cmd+I.

8. Go to the tab Build.

9. Select the Configuration named Distribution.

10. Find the section Code Signing.

11. Set the value of Code Signing Identity / Any iPhone OS Device to iPhone Distribution.

12. Close the Target Info pane.

13. In the main window select the Active Configuration to Distribution.

14. Create a new file from the file template Code Signing / Entitlements.

15. Name it Entitlements.plist.

16. In this file, uncheck the checkbox get-task-allow.

17. Bring up the Target Info pane, and find the section Code Signing again.

18. After Code Signing Entitlements enter the file name Entitlements.plist.

19. Save, clean, and build the project.

20. In Groups & Files find the folder MyApp / Products and expand it.

21. Right click the app and select Reveal in Finder.

22. Zip the .app file and the .mobileprovision file and send the archive to your tester.

    Here is my app. To install it onto your phone:

    1. Unzip the archive file.

    2. Open iTunes.

    3. Drag both files into iTunes and drop them on the Library group.

    4. Sync your phone to install the app.

Done! Phew. This worked for me. So far I've only added one tester.

I used the actual answer to this post (url) and writing the output into a file.

package test;

import java.net.*;
import java.io.*;

public class PDFTest {
    public static void main(String[] args) throws Exception {
    try {
        URL oracle = new URL("http://www.fetagracollege.org");
        BufferedReader in = new BufferedReader(new InputStreamReader(oracle.openStream()));

        String fileName = "D:\\a_01\\output.txt";

        PrintWriter writer = new PrintWriter(fileName, "UTF-8");
        OutputStream outputStream = new FileOutputStream(fileName);
        String inputLine;

        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
            writer.println(inputLine);
        }
        in.close();
        } catch(Exception e) {

        }

    }
}

You can directly call

getFragmentManager() 

to get the fragment manager.

or

In your fragment,

Create field :

private FragmentActivity myContext;

override onAttach method of your fragment :

@Override
public void onAttach(Activity activity) {
    myContext=(FragmentActivity) activity;
    super.onAttach(activity);
}

When you need to get Support fragment manager call :

FragmentManager fragManager = myContext.getSupportFragmentManager(); //If using fragments from support v4

or

FragmentManager fragManager = myContext.getFragmentManager();

You are done.

As far as your question goes: no, if activating from .ini is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap, yum install php-soap). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).

In general, the double-dash --switches are designed to be used when recompiling PHP from scratch.

You would download the PHP source package (as a compressed .tgz tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script

./configure --prefix ...

The configure command used by your PHP may be shown with phpinfo(). Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap will then enable SOAP in addition to everything else.

That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype, gd, libjpeg, XML, expat, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg installed might not be enough, and you might need libjpeg-dev also).

I have to keep a separate virtual machine with everything installed for my recompilation purposes.

Just so others who have configured their apps like mine benefit from what I went through...

None of the above solutions worked for me because I have a ./config directory just under my project base with 2 files:

application.properties
application-dev.properties

In application.properties I have:

spring.profiles.active = dev  # set my default profile to 'dev'

In application-dev.properties I have:

server_host = localhost
server_port = 8080

This is so when I run my fat jar from the CLI the *.properties files will be read from the ./config dir and all is good.

Well, it turns out that these properties files completely override the webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT setting in @SpringBootTest in my Spock specs. No matter what I tried, even with webEnvironment set to RANDOM_PORT Spring would always startup the embedded Tomcat container on port 8080 (or whatever value I'd set in my ./config/*.properties files).

The ONLY way I was able to overcome this was by adding an explicit properties = "server_port=0" to the @SpringBootTest annotation in my Spock integration specs:

@SpringBootTest (webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "server_port=0")

Then, and only then did Spring finally start to spin up Tomcat on a random port. IMHO this is a Spring testing framework bug, but I'm sure they'll have their own opinion on this.

Hope this helped someone.

The composer documentation states that:

After adding the autoload field, you have to re-run install to re-generate the vendor/autoload.php file.

Assuming your "src" dir resides at the same level as "vendor" dir:

• src
  • AppName
• vendor
• composer.json

the following config is absolutely correct:

{
    "autoload": {
        "psr-0": {"AppName": "src/"}
    }
}

but you must re-update/install dependencies to make it work for you, i.e. run:

php composer.phar update

This command will get the latest versions of the dependencies and update the file "vendor/composer/autoload_namespaces.php" to match your configuration.

Also as noted by @Dom, you can use composer dump-autoload to update the autoloader without having to go through an update.

After hours of struggling, I solved it by including the following within app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Let's illustrate what's happening here:

Python 3.1.2 (r312:79147, Sep 27 2010, 09:45:41) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Foo:
...     def __init__(self, x=[]):
...         x.append(1)
... 
>>> Foo.__init__.__defaults__
([],)
>>> f = Foo()
>>> Foo.__init__.__defaults__
([1],)
>>> f2 = Foo()
>>> Foo.__init__.__defaults__
([1, 1],)

You can see that the default arguments are stored in a tuple which is an attribute of the function in question. This actually has nothing to do with the class in question and goes for any function. In python 2, the attribute will be func.func_defaults.

As other posters have pointed out, you probably want to use None as a sentinel value and give each instance it's own list.

I think this solution uses less code and is easy to understand even for newbie.

For string field in struct, you can use pointer and reassigning the string to that pointer will be straightforward and simpler.

Define definition of struct:

typedef struct {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} Patient;

Initialize variable with type of that struct:

Patient patient;
patient.number = 12345;
patient.address = "123/123 some road Rd.";
patient.birthdate = "2020/12/12";
patient.gender = "M";

It is that simple. Hope this answer helps many developers.

I found this question because I wanted to pose a question why there is a performance impact if one uses nested functions. I ran tests for the following functions using Python 3.2.5 on a Windows Notebook with a Quad Core 2.5 GHz Intel i5-2530M processor

def square0(x):
    return x*x

def square1(x):
    def dummy(y):
        return y*y
    return x*x

def square2(x):
    def dummy1(y):
        return y*y
    def dummy2(y):
        return y*y
    return x*x

def square5(x):
    def dummy1(y):
        return y*y
    def dummy2(y):
        return y*y
    def dummy3(y):
        return y*y
    def dummy4(y):
        return y*y
    def dummy5(y):
        return y*y
    return x*x

I measured the following 20 times, also for square1, square2, and square5:

s=0
for i in range(10**6):
    s+=square0(i)

and got the following results

>>> 
m = mean, s = standard deviation, m0 = mean of first testcase
[m-3s,m+3s] is a 0.997 confidence interval if normal distributed

square? m     s       m/m0  [m-3s ,m+3s ]
square0 0.387 0.01515 1.000 [0.342,0.433]
square1 0.460 0.01422 1.188 [0.417,0.503]
square2 0.552 0.01803 1.425 [0.498,0.606]
square5 0.766 0.01654 1.979 [0.717,0.816]
>>> 

square0 has no nested function, square1 has one nested function, square2 has two nested functions and square5 has five nested functions. The nested functions are only declared but not called.

So if you have defined 5 nested funtions in a function that you don't call then the execution time of the function is twice of the function without a nested function. I think should be cautious when using nested functions.

The Python file for the whole test that generates this output can be found at ideone.

In short, phpunit supresses STDOUT. It writes to STDERR by default, unless you add --verbose or --debug . You can do one of those things:

• print your debug output to STDERR instead
• var_dump your debug as usual but add --verbose to the phpunit command line
• var_dump your debug as usual but add a line ob_flush(); beneath it
• use the correct commands in phpunit for testing exactly what you're trying to test here

Obviously, the last thing is the Good Thing to do, and the rest are quick temporary hacks.

Simply add these to your ggplot:

+ scale_x_continuous(expand = c(0, 0), limits = c(0, NA)) + 
  scale_y_continuous(expand = c(0, 0), limits = c(0, NA))

Example

df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for


p + scale_x_continuous(expand = c(0, 0), limits = c(0,NA)) + 
  scale_y_continuous(expand = c(0, 0), limits = c(0, NA))

Lastly, take great care not to unintentionally exclude data off your chart. For example, a position = 'dodge' could cause a bar to get left off the chart entirely (e.g. if its value is zero and you start the axis at zero), so you may not see it and may not even know it's there. I recommend plotting data in full first, inspect, then use the above tip to improve the plot's aesthetics.

Hi url should be calling a function which in return will give response

If sometimes a link! will not work. so create a temporary object and take all values from the writable object then change the value and assign it to the writable object. it should perfectly.

var globalObject = {
    name:"a",
    age:20
}
function() {
    let localObject = {
    name:'a',
    age:21
    }
    this.globalObject = localObject;
}

This works with Browser and Hash history.

this.props.history.goBack();

One thing with patterns: don't generalize. They have all cases when they're useful, and when they fail.

Singleton can be nasty when you have to test the code. You're generally stuck with one instance of the class, and can choose between opening up a door in constructor or some method to reset the state and so on.

Other problem is that the Singleton in fact is nothing more than a global variable in disguise. When you have too much global shared state over your program, things tend to go back, we all know it.

It may make dependency tracking harder. When everything depends on your Singleton, it's harder to change it, split to two, etc. You're generally stuck with it. This also hampers flexibility. Investigate some Dependency Injection framework to try to alleviate this issue.

If you are using the official mysql docker container, there is a simple solution:

Add the following line to your docker-compose service:

command: --default-authentication-plugin=mysql_native_password

Example configuration:

mysql:
     image: mysql:8
     networks:
       - net_internal
     volumes:
       - mysql_data:/var/lib/mysql
     environment:
       - MYSQL_ROOT_PASSWORD=root
       - MYSQL_DATABASE=db
     command: --default-authentication-plugin=mysql_native_password

If "validation failure" means that there is some client error in the request, then use HTTP 400 (Bad Request). For instance if the URI is supposed to have an ISO-8601 date and you find that it's in the wrong format or refers to February 31st, then you would return an HTTP 400. Ditto if you expect well-formed XML in an entity body and it fails to parse.

(1/2016): Over the last five years WebDAV's more specific HTTP 422 (Unprocessable Entity) has become a very reasonable alternative to HTTP 400. See for instance its use in JSON API. But do note that HTTP 422 has not made it into HTTP 1.1, RFC-7231.

Richardson and Ruby's RESTful Web Services contains a very helpful appendix on when to use the various HTTP response codes. They say:

400 (“Bad Request”)
Importance: High.
This is the generic client-side error status, used when no other 4xx error code is appropriate. It’s commonly used when the client submits a representation along with a PUT or POST request, and the representation is in the right format, but it doesn’t make any sense. (p. 381)

and:

401 (“Unauthorized”)
Importance: High.
The client tried to operate on a protected resource without providing the proper authentication credentials. It may have provided the wrong credentials, or none at all. The credentials may be a username and password, an API key, or an authentication token—whatever the service in question is expecting. It’s common for a client to make a request for a URI and accept a 401 just so it knows what kind of credentials to send and in what format. [...]

For casting varchar fields/values to number format can be little hack used:

SELECT (`PROD_CODE` * 1) AS `PROD_CODE` FROM PRODUCT`

This works in 2020!

As others said create "MANIFEST.in" where your setup.py is located.

Next in manifest include/exclude all the necessary things. Be careful here regarding the syntax. Ex: lets say we have template folder to be included in the source package.

in manifest file do this :

recursive-include template *

Make sure you leave space between dir-name and pattern for files/dirs like above. Dont do like this like we do in .gitignore

recursive-include template/* [this won't work]

Other option is to use include. There are bunch of options. Look up here at their docs for Manifest.in

And the final important step, include this param in your setup.py and you are good to go!

   setup(
    ...
    include_package_data=True,
    ......
)

Hope that helps! Happy Coding!

I'll probably get flamed for this, but what is the point of testing for existence if you are just going to delete it? One of my major pet peeves is an app throwing an error dialog with something like "Could not delete file, it does not exist!"

On Error Resume Next
aFile = "c:\file_to_delete.txt"
Kill aFile
On Error Goto 0
return Len(Dir$(aFile)) > 0 ' Make sure it actually got deleted.

If the file doesn't exist in the first place, mission accomplished!

If you have a mysql timestamp, something like 2013-09-29 22:27:10 you can do this

 select * from table WHERE MONTH(FROM_UNIXTIME(UNIX_TIMESTAMP(time)))=9;

Convert to unix, then use the unix time functions to extract the month, in this case 9 for september.

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

After Pulling hair for a long time,I finally found an issue.I've selected wrong certificate while creating Provisioning Profile,By selecting right one,It helped for me.In your case,If it is multiple then You have to try and select one by one to get this issue solved.

I tried the above answer - using page.html#ID_name it gave me a 404 page doesn't exist error.

Then instead of using .html, I simply put a slash / before the # and that worked fine. So my example on the sending page between the link tags looks like:

<a href= "http://my website.com/target-page/#El_Chorro">El Chorro</a>

Just use / instead of .html.

How I update my deviceToken

First when I login I send the first device token under the user collection and the current logged in user.

After that, I just override onNewToken(token:String) in my FirebaseMessagingService() and just update that value if a new token is generated for that user

class MyFirebaseMessagingService: FirebaseMessagingService() {
    override fun onMessageReceived(p0: RemoteMessage) {
        super.onMessageReceived(p0)
    }

    override fun onNewToken(token: String) {
    super.onNewToken(token)
    val currentUser= FirebaseAuth.getInstance().currentUser?.uid
    if(currentUser != null){
        FirebaseFirestore.getInstance().collection("user").document(currentUser).update("deviceToken",token)
    }
 }
} 

Each time your app opens it will check for a new token, if the user is not yet signed in it will not update the token, if the user is already logged in you can check for a newToken

You need to slightly modify your compare function and use functools.cmp_to_key to pass it to sorted. Example code:

import functools

lst = [list(range(i, i+5)) for i in range(5, 1, -1)]

def fitness(item):
    return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
    return fitness(item1) - fitness(item2)

sorted(lst, key=functools.cmp_to_key(compare))

Output:

[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]

Works :)

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

I use AutoMapper for this. It works like this:

Mapper.CreateMap(typeof(Person), typeof(Person));
Mapper.Map(a, b);

Now person a has all the properties of person b.

As an aside, AutoMapper works for differing objects as well. For more information, check it out at http://automapper.org

Update: I use this syntax now (simplistically - really the CreateMaps are in AutoMapper profiles):

Mapper.CreateMap<Person, Person>;
Mapper.Map(a, b);

Note that you don't have to do a CreateMap to map one object of the same type to another, but if you don't, AutoMapper will create a shallow copy, meaning to the lay man that if you change one object, the other changes also.

Below is a class which will accomplish the very basics of what you want to do when reading data from a MySQL database into a JTable in Java.

import java.awt.*;

In the NetBeans IDE which you are using - you will need to add the MySQL JDBC Driver in Project Properties as I display here:

Otherwise the code will throw an SQLException stating that the driver cannot be found.

Now in my example, yourdb is the name of the database and animals is the name of the table that I am performing a query against.

Here is what will be output:

Parting note:

You stated that you were a novice and needed some help understanding some of the basic classes and concepts of Java. I will list a few here, but remember you can always browse the docs on Oracle's site.

• ArrayList
• Vector
• Try-with-resources statement

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

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

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

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

XOR behaves like Austin explained, as an exclusive OR, either A or B but not both and neither yields false.

There are 16 possible logical operators for two inputs since the truth table consists of 4 combinations there are 16 possible ways to arrange two boolean parameters and the corresponding output.

They all have names according to this wikipedia article

In the first line of your JS code:

select.addEventListener('change', getSelection(this), false);

you're invoking getSelection by placing (this) behind the function reference. That is most likely not what you want, because you're now passing the return value of that call to addEventListener, instead of a reference to the actual function itself.

In a function invoked by addEventListener the value for this will automatically be set to the object the listener is attached to, productLineSelect in this case.

If that is what you want, you can just pass the function reference and this will in this example be select in invocations from addEventListener:

select.addEventListener('change', getSelection, false);

If that is not what you want, you'd best bind your value for this to the function you're passing to addEventListener:

var thisArg = { custom: 'object' };
select.addEventListener('change', getSelection.bind(thisArg), false);

The .bind part is also a call, but this call just returns the same function we're calling bind on, with the value for this inside that function scope fixed to thisArg, effectively overriding the dynamic nature of this-binding.

To get to your actual question: "How to pass parameters to function in addEventListener?"

You would have to use an additional function definition:

var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}, false);

Now we pass the event object, a reference to the value of this inside the callback of addEventListener, a variable defined and initialised inside that callback, and a variable from outside the entire addEventListener call to your own getSelection function.

We also might again have an object of our choice to be this inside the outer callback:

var thisArg = { custom: 'object' };
var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}.bind(thisArg), false);

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

This is not a bug in either implementation. There is no requirement to escape U+00B0. To quote the RFC:

2.5. Strings

The representation of strings is similar to conventions used in the C family of programming languages. A string begins and ends with quotation marks. All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).

Any character may be escaped.

Escaping everything inflates the size of the data (all code points can be represented in four or fewer bytes in all Unicode transformation formats; whereas encoding them all makes them six or twelve bytes).

It is more likely that you have a text transcoding bug somewhere in your code and escaping everything in the ASCII subset masks the problem. It is a requirement of the JSON spec that all data use a Unicode encoding.

You can try this.

import React from 'react';
import RippleButton from '../../Components/RippleButton/rippleButton.jsx';

class HtmlComponents extends React.Component {

    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }

    rippleClickFunction(){
        //do stuff. 
        // foo==bar
    }

    render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

Yhe only concern is you have to bind the context to the function

You can try,

 <?php

     if (isset($_POST["mail"])) {
            echo "Yes, mail is set";    
        }else{  
            echo "N0, mail is not set";
        }
  ?>

If it is something to do with the data in your database, why not utilize database isolation locking to achieve?

#y.x should work. And it's convenient too. You can make a page with different kinds of output. You can give a certain element an id, but give it different classes depending on the look you want.

You can use the following to refresh the page by clicking the back button:

window.addEventListener('popstate', () => {
  location.reload();
}, false);

SMH, a lot of hours wasted on this due to lack of proper documentation and not everyone uses IIS... If anyone else is still stuck on this issue I hope this helps.

Solution: Trusted Self Signed SSL CERT for localhost on Windows 10

Note: If you only need the SSL cert follow the Certification Creation section

Stack: Azure Function App(Node.js), React.js - Windows 10

Certification Creation

Step 1 - Create Certificate: OpenPowershell and run the following:

New-SelfSignedCertificate -NotBefore (Get-Date) -NotAfter (Get-Date).AddYears(5) `
-Subject "CN=localhost" -KeyAlgorithm "RSA" -KeyLength 2048 `
-HashAlgorithm "SHA256" -CertStoreLocation "Cert:\CurrentUser\My" `
-FriendlyName "HTTPS Development Certificate" `
-TextExtension @("2.5.29.19={text}","2.5.29.17={text}DNS=localhost")

Step 2 - Copy Certificate: Open Certificate Manager by pressing the windows key and search for "manage user certificates". Navigate to Personal -> Certificates and copy the localhost cert to Trusted Root Certification Authorities -> Certificates

Personal -> Certificates

Trusted Root Certification Authorities -> Certificates

(Friendly Name will be HTTPS Development Certificate)

Step 3. Export Certificate right click cert -> All Tasks -> Export which will launch the Certificate Export Wizard: Certificate Export Wizard

• Click next
• Select Yes, export the private Key Export private key
• Select the following format Personal Information Exchange - PKCS #12 and leave the first and last checkboxes selected. Export format
• Select a password; enter something simple if you like ex. "1111" Enter password
• Save file to a location you will remember ex. Desktop or Sites (you can name the file development.pfx) Save file

Step 4. Restart Chrome

Azure Function App (Server) - SSL Locally with .PFX

In this case we will run an Azure Function App with the SSL cert.

• copy the exported development.pfx file to your azure functions project root
• from cmd.exe run the following to start your functions app func start --useHttps --cert development.pfx --password 1111" (If you used a different password and filename don't forget to update the values in this script)
• Update your package.json scripts to start your functions app:

React App (Client) - Run with local SSL

Install openssl locally, this will be used to convert the development.pfx to a cert.pem and server.key. Source - Convert pfx to pem file

1. open your react app project root and create a cert folder. (project-root/cert)
2. create a copy of the development.pfx file in the cert folder. (project-root /cert/development.pfx)
3. open command prompt from the cert directory and run the following:
4. convert development.pfx to cert.pem: openssl pkcs12 -in development.pfx -out cert.pem -nodes
5. extract private key from development.pfx to key.pem: openssl pkcs12 -in development.pfx -nocerts -out key.pem
6. remove password from the extracted private key: openssl rsa -in key.pem -out server.key
7. update your .env.development.local file by adding the following lines:

SSL_CRT_FILE=cert.pem
SSL_KEY_FILE=server.key

8. start your react app npm start

The Abstract Factory pattern is used in various places. E.g., DatagramSocketImplFactory, PreferencesFactory. There are many more---search the Javadoc for interfaces which have the word "Factory" in their name.

Also there are quite a few instances of the Factory pattern, too.

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

Consider this as your select list:

<select onchange="var optionVal = $(this).find(':selected').val(); doSomething(optionVal)">

                                <option value="mostSeen">Most Seen</option>
                                <option value="newst">Newest</option>
                                <option value="mostSell">Most Sell</option>
                                <option value="mostCheap">Most Cheap</option>
                                <option value="mostExpensive">Most Expensive</option>

                            </select>

then you check selected option like this:

function doSomething(param) {

    if ($(param.selected)) {
        alert(param + ' is selected!');
    }

}

You shouldn't be using an item defined in the Layout XML in order to create more instances of it. You should either create it in a separate XML and inflate it or create the TableRow programmaticaly. If creating them programmaticaly, should be something like this:

    public void init(){
    TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);


    for (int i = 0; i <2; i++) {

        TableRow row= new TableRow(this);
        TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
        row.setLayoutParams(lp);
        checkBox = new CheckBox(this);
        tv = new TextView(this);
        addBtn = new ImageButton(this);
        addBtn.setImageResource(R.drawable.add);
        minusBtn = new ImageButton(this);
        minusBtn.setImageResource(R.drawable.minus);
        qty = new TextView(this);
        checkBox.setText("hello");
        qty.setText("10");
        row.addView(checkBox);
        row.addView(minusBtn);
        row.addView(qty);
        row.addView(addBtn);
        ll.addView(row,i);
    }
}

In VueJS you can loop through an array like this : const array1 = ['a', 'b', 'c'];

Array.from(array1).forEach(element => 
 console.log(element)
      );

in my case I want to loop through files and add their types to another array:

 Array.from(files).forEach((file) => {
       if(this.mediaTypes.image.includes(file.type)) {
            this.media.images.push(file)
             console.log(this.media.images)
       }
   }

git remote add => ADDS a new remote.

git remote set-url => UPDATES existing remote.

1. The remote name that comes after add is a new remote name that did not exist prior to that command.
2. The remote name that comes after set-url should already exist as a remote name to your repository.

git remote add myupstream someurl => myupstream remote name did not exist now creating it with this command.

git remote set-url upstream someurl => upstream remote name already exist i'm just changing it's url.

git remote add myupstream https://github.com/nodejs/node => **ADD** If you don't already have upstream
git remote set-url upstream https://github.com/nodejs/node # => **UPDATE** url for upstream

<section [ngClass]="{'class1': expression1, 'class2': expression2, 
'class3': expression3}">

Don't forget to add single quotes around class names.

Could also simply implement a validation rule and apply it to the TextBox:

  <TextBox>
    <TextBox.Text>
      <Binding Path="OnyDigitInput" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged">
        <Binding.ValidationRules>
          <conv:OnlyDigitsValidationRule />
        </Binding.ValidationRules>
      </Binding>
    </TextBox.Text>

With the implementation of the rule as follow (using the same Regex as proposed in other answers):

public class OnlyDigitsValidationRule : ValidationRule
{
    public override ValidationResult Validate(object value, CultureInfo cultureInfo)
    {
        var validationResult = new ValidationResult(true, null);

        if(value != null)
        {
            if (!string.IsNullOrEmpty(value.ToString()))
            {
                var regex = new Regex("[^0-9.-]+"); //regex that matches disallowed text
                var parsingOk = !regex.IsMatch(value.ToString());
                if (!parsingOk)
                {
                    validationResult = new ValidationResult(false, "Illegal Characters, Please Enter Numeric Value");
                }
            }
        }

        return validationResult;
    }
}

Use the iconv command.

To make sure the file is in Windows-1252, open it in Notepad (under Windows), then click Save As. Notepad suggests current encoding as the default; if it's Windows-1252 (or any 1-byte codepage, for that matter), it would say "ANSI".

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

You can add references to your model through command line in the following manner:

rails g migration add_column_to_tester user_id:integer

This will generate a migration file like :

class AddColumnToTesters < ActiveRecord::Migration
  def change
    add_column :testers, :user_id, :integer
  end
end

This works fine every time i use it..

Take a look at this code,

CREATE PROCEDURE Test

AS
    DECLARE @tab table (no int, name varchar(30))

    insert @tab  select eno,ename from emp  

    select * from @tab
RETURN

The reason your code doesn't work is because the count function is asynchronous, it doesn't synchronously return a value.

Here's an example of usage:

userModel.count({}, function( err, count){
    console.log( "Number of users:", count );
})

netstat on Solaris will not tell you this, nor will older versions of lsof, but if you download and build/install a newer version of lsof, this can tell you that.

$ lsof -v

With this you can use the -i option:

$ lsof -i:22

Which shows you exactly what you're asking for.

I had a problem yesterday with a crashed Jetty (Java) process, which only left 2 files in its /proc/[PID] directory (psinfo & usage).

pfiles failed to find the process (because the date it needed was not there)

lsof found it for me.

Had the same issue. Turns out I was using " instead of '.

use @import url('within single quotes'); like this

not @import url("within double quotes"); like this

For Unix like users (Linux/MacOs X), instead of removing ~/.gradle/caches/, in command line do :

$ cd path_to_you_project
$ touch build.gradle

Then ask Android Studio to build APK, it will reset gradle cache itself.

Since C++11, there's a safe alternative to new[] and delete[] which is zero-overhead unlike std::vector:

std::unique_ptr<int[]> array(new int[size]);

In C++14:

auto array = std::make_unique<int[]>(size);

Both of the above rely on the same header file, #include <memory>

Try by changing X[:,3] to X.iloc[:,3] in label encoder

In Mvc 4 you can use AcceptVerbsAttribute, I think this is a very clean solution

[AcceptVerbs(WebRequestMethods.Http.Get, WebRequestMethods.Http.Post)]
public IHttpActionResult Login()
{
   // Login logic
}

I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

This may be OLD, but here is the best answer:

    float dist = (float) Math.sqrt(
            Math.pow(x1 - x2, 2) +
            Math.pow(y1 - y2, 2) );

As found on the mailing list archive,

• http://osdir.com/ml/gnu.make.windows/2004-03/msg00063.html
• http://osdir.com/ml/gnu.make.general/2005-10/msg00064.html

one can use the filter function.

For example

ifeq ($(GCC_MINOR),$(filter $(GCC_MINOR),4 5))

filter X, A B will return those of A,B that are equal to X. Note, while this is not relevant in the above example, this is a XOR operation. I.e. if you instead have something like:

ifeq (4, $(filter 4, $(VAR1) $(VAR2)))

And then do e.g. make VAR1=4 VAR2=4, the filter will return 4 4, which is not equal to 4.

A variation that performs an OR operation instead is:

ifneq (,$(filter $(GCC_MINOR),4 5))

where a negative comparison against an empty string is used instead (filter will return en empty string if GCC_MINOR doesn't match the arguments). Using the VAR1/VAR2 example it would look like this:

ifneq (, $(filter 4, $(VAR1) $(VAR2)))

The downside to those methods is that you have to be sure that these arguments will always be single words. For example, if VAR1 is 4 foo, the filter result is still 4, and the ifneq expression is still true. If VAR1 is 4 5, the filter result is 4 5 and the ifneq expression is true.

One easy alternative is to just put the same operation in both the ifeq and else ifeq branch, e.g. like this:

ifeq ($(GCC_MINOR),4)
    @echo Supported version
else ifeq ($(GCC_MINOR),5)
    @echo Supported version
else
    @echo Unsupported version
endif

To remove a record.

 var db = firebase.database();                   
 var ref = db.ref(); 
 var survey=db.ref(path+'/'+path);    //Eg path is company/employee                
 survey.child(key).remove();          //Eg key is employee id

X returns (value +3), while Y returns (value*2)

Given a value of 4, this means (4+3) * (4*2) = 7 * 8 = 56.

Although functions are not limited in scope (which means that you can safely 'nest' function definitions), this particular example is prone to errors:

1) You can't call y() before calling x(), because function y() won't actually be defined until x() has executed once.

2) Calling x() twice will cause PHP to redeclare function y(), leading to a fatal error:

Fatal error: Cannot redeclare y()

The solution to both would be to split the code, so that both functions are declared independent of each other:

function x ($y) 
{
  return($y+3);
}

function y ($z)
{
  return ($z*2);
}

This is also a lot more readable.

You just need to specify which columns you're inserting directly into:

INSERT INTO [dbo].[rLicenses] ([Name]) VALUES ('test')

Views can be picky like that.

I had this same problem, and after some searching around, I found Reggie (https://github.com/mbrevoort/node-reggie). It looks pretty solid. It allows for lightweight publishing of NPM modules to private servers. Not perfect (no authentication upon installation), and it's still really young, but I tested it locally, and it seems to do what it says it should do.

That is... (and this just from their docs)

npm install -g reggie
reggie-server -d ~/.reggie

then cd into your module directory and...

reggie -u http://<host:port> publish 
reggie -u http://127.0.0.1:8080 publish 

finally, you can install packages from reggie just by using that url either in a direct npm install command, or from within a package.json... like so

npm install http://<host:port>/package/<name>/<version>
npm install http://<host:port>/package/foo/1.0.0

or..

dependencies: {
    "foo": "http://<host:port>/package/foo/1.0.0"
}

IF you need to softly suppress the delete and backspace keys in your Web app, so that when they are editing / deleting items the page does not get redirected unexpectedly, you can use this code:

window.addEventListener('keydown', function(e) {
  var key = e.keyCode || e.which;
  if (key == 8 /*BACKSPACE*/ || key == 46/*DELETE*/) {
    var len=window.location.href.length;
    if(window.location.href[len-1]!='#') window.location.href += "#";
  }
},false);

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

import java.util.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public static String get_match(String s, String p) {
    // returns first match of p in s for first group in regular expression 
    Matcher m = Pattern.compile(p).matcher(s);
    return m.find() ? m.group(1) : "";
}

get_match("FOO[BAR]", "\\[(.*?)\\]")  // returns "BAR"

public static List<String> get_matches(String s, String p) {
    // returns all matches of p in s for first group in regular expression 
    List<String> matches = new ArrayList<String>();
    Matcher m = Pattern.compile(p).matcher(s);
    while(m.find()) {
        matches.add(m.group(1));
    }
    return matches;
}

get_matches("FOO[BAR] FOO[CAT]", "\\[(.*?)\\]")) // returns [BAR, CAT]

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

If it might spare some time I was looking to get:

In case someone is still wondering how to do this without jQuery.

HTML

<textarea id="description"></textarea>

Javascript

const textarea = document.getElementById('description');

textarea.addEventListener('keypress', (e) => {
    e.keyCode === 13 && !e.shiftKey && e.preventDefault(); 
})

Vanilla JS

var textarea = document.getElementById('description');

textarea.addEventListener('keypress', function(e) {
    if(e.keyCode === 13 && !e.shiftKey) {
      e.preventDefault();
    }
})

1. type git add . && git commit -am and enter
2. type historyand enter
3. remember the number for the above command, say the number is 543
4. From now on, for every commit type !543 "your comment here" i.e. exclamatory mark+number and a space and your comment.

result_array() returns Associative Array type data. Returning pure array is slightly faster than returning an array of objects. result() is recursive in that it returns an std class object where as result_array() just returns a pure array, so result_array() would be choice regarding performance.

Since the username and password is added in config.inc.php, you need to change:

$cfg['Servers'][$i]['auth_type'] = 'cookie';

TO:

$cfg['Servers'][$i]['auth_type'] = 'config';

And save the file.

You will then need to restart WAMP after making the above changes.

You have to edit the PHP configuration file. Find the line

error_reporting = E_ALL

and replace it with:

error_reporting = E_ALL ^ E_DEPRECATED

If you don't have access to the configuration file you can add this line to the PHP WordPress file (maybe headers.php):

error_reporting(E_ALL ^ E_DEPRECATED);

This question helped me a lot but didn't get me all the way in understanding what needs to happen. This blog post did an amazing job of walking me through it.

Here are the important bits all in one place:

• As pointed out above, you MUST sign your 1.1 API requests. If you are doing something like getting public statuses, you'll want an application key rather than a user key. The full link to the page you want is: https://dev.twitter.com/apps
• You must hash ALL the parameters, both the oauth ones AND the get parameters (or POST parameters) together.
• You must SORT the parameters before reducing them to the url encoded form that gets hashed.
• You must encode some things multiple times - for example, you create a query string from the parameters' url-encoded values, and then you url encode THAT and concatenate with the method type and the url.

I sympathize with all the headaches, so here's some code to wrap it all up:

$token = 'YOUR TOKEN';
$token_secret = 'TOKEN SECRET';
$consumer_key = 'YOUR KEY';
$consumer_secret = 'KEY SECRET';

$host = 'api.twitter.com';
$method = 'GET';
$path = '/1.1/statuses/user_timeline.json'; // api call path

$query = array( // query parameters
    'screen_name' => 'twitterapi',
    'count' => '2'
);

$oauth = array(
    'oauth_consumer_key' => $consumer_key,
    'oauth_token' => $token,
    'oauth_nonce' => (string)mt_rand(), // a stronger nonce is recommended
    'oauth_timestamp' => time(),
    'oauth_signature_method' => 'HMAC-SHA1',
    'oauth_version' => '1.0'
);

$oauth = array_map("rawurlencode", $oauth); // must be encoded before sorting
$query = array_map("rawurlencode", $query);

$arr = array_merge($oauth, $query); // combine the values THEN sort

asort($arr); // secondary sort (value)
ksort($arr); // primary sort (key)

// http_build_query automatically encodes, but our parameters
// are already encoded, and must be by this point, so we undo
// the encoding step
$querystring = urldecode(http_build_query($arr, '', '&'));

$url = "https://$host$path";

// mash everything together for the text to hash
$base_string = $method."&".rawurlencode($url)."&".rawurlencode($querystring);

// same with the key
$key = rawurlencode($consumer_secret)."&".rawurlencode($token_secret);

// generate the hash
$signature = rawurlencode(base64_encode(hash_hmac('sha1', $base_string, $key, true)));

// this time we're using a normal GET query, and we're only encoding the query params
// (without the oauth params)
$url .= "?".http_build_query($query);

$oauth['oauth_signature'] = $signature; // don't want to abandon all that work!
ksort($oauth); // probably not necessary, but twitter's demo does it

// also not necessary, but twitter's demo does this too
function add_quotes($str) { return '"'.$str.'"'; }
$oauth = array_map("add_quotes", $oauth);

// this is the full value of the Authorization line
$auth = "OAuth " . urldecode(http_build_query($oauth, '', ', '));

// if you're doing post, you need to skip the GET building above
// and instead supply query parameters to CURLOPT_POSTFIELDS
$options = array( CURLOPT_HTTPHEADER => array("Authorization: $auth"),
                  //CURLOPT_POSTFIELDS => $postfields,
                  CURLOPT_HEADER => false,
                  CURLOPT_URL => $url,
                  CURLOPT_RETURNTRANSFER => true,
                  CURLOPT_SSL_VERIFYPEER => false);

// do our business
$feed = curl_init();
curl_setopt_array($feed, $options);
$json = curl_exec($feed);
curl_close($feed);

$twitter_data = json_decode($json);

Swift 4.2+ String to Double

You should use the new type initializers to convert between String and numeric types (Double, Float, Int). It'll return an Optional type (Double?) which will have the correct value or nil if the String was not a number.

Note: The NSString doubleValue property is not recommended because it returns 0 if the value cannot be converted (i.e.: bad user input).

let lessPrecisePI = Float("3.14")

let morePrecisePI = Double("3.1415926536")
let invalidNumber = Float("alphabet") // nil, not a valid number

Unwrap the values to use them using if/let

if let cost = Double(textField.text!) {
    print("The user entered a value price of \(cost)")
} else {
    print("Not a valid number: \(textField.text!)")
}

You can convert formatted numbers and currency using the NumberFormatter class.

let formatter = NumberFormatter()
formatter.locale = Locale.current // USA: Locale(identifier: "en_US")
formatter.numberStyle = .decimal
let number = formatter.number(from: "9,999.99")

Currency formats

let usLocale = Locale(identifier: "en_US")
let frenchLocale = Locale(identifier: "fr_FR")
let germanLocale = Locale(identifier: "de_DE")
let englishUKLocale = Locale(identifier: "en_GB") // United Kingdom
formatter.numberStyle = .currency

formatter.locale = usLocale
let usCurrency = formatter.number(from: "$9,999.99")

formatter.locale = frenchLocale
let frenchCurrency = formatter.number(from: "9999,99€")
// Note: "9 999,99€" fails with grouping separator
// Note: "9999,99 €" fails with a space before the €

formatter.locale = germanLocale
let germanCurrency = formatter.number(from: "9999,99€")
// Note: "9.999,99€" fails with grouping separator

formatter.locale = englishUKLocale
let englishUKCurrency = formatter.number(from: "£9,999.99")

Read more on my blog post about converting String to Double types (and currency).

Suppose your function enters data in columns A and B and you want to a custom Userform to appear if the user selects a cell in column C. One way to do this is to use the SelectionChange event:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim clickRng As Range
    Dim lastRow As Long

    lastRow = Range("A1").End(xlDown).Row
    Set clickRng = Range("C1:C" & lastRow) //Dynamically set cells that can be clicked based on data in column A

    If Not Intersect(Target, clickRng) Is Nothing Then
        MyUserForm.Show //Launch custom userform
    End If

End Sub

Note that the userform will appear when a user selects any cell in Column C and you might want to populate each cell in Column C with something like "select cell to launch form" to make it obvious that the user needs to perform an action (having a button naturally suggests that it should be clicked)

I did the same as @Moesio Above but in Kotlin it could be done this way:

class A<T : SomeClass>() {

    var someClassType : T

    init(){
    this.someClassType = (javaClass.genericSuperclass as ParameterizedType).actualTypeArguments[0] as Class<T>
    }

}

I tried all the different things mentioned here to get the index of the . character in a filename that ends with .[0-9][0-9]*, e.g. srcfile.1, srcfile.12, etc. Nothing worked. Finally, the following worked: int dotIndex = inputfilename.lastIndexOf(".");

Weird! This is with java -version:

openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-0ubuntu1.16.10.2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

Also, the official Java doc page for regex (from which there is a quote in one of the answers above) does not seem to specify how to look for the . character. Because \., \\., and [.] did not work for me, and I don't see any other options specified apart from these.

You might be using the wrong approach. Just because one thread that simulates a car finishes before another car-simulation thread doesn't mean that the first thread should win the simulated race.

It depends a lot on your application, but it might be better to have one thread that computes the state of all cars at small time intervals until the race is complete. Or, if you prefer to use multiple threads, you might have each car record the "simulated" time it took to complete the race, and choose the winner as the one with shortest time.

One line of code using jQuery:

$('td:nth-child(2)').hide();

// If your table has header(th), use this:
//$('td:nth-child(2),th:nth-child(2)').hide();

for 1.0.4:

io.sockets.on('connection', function (socket) {
  var socketId = socket.id;
  var clientIp = socket.request.connection.remoteAddress;

  console.log(clientIp);
});

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))
    ax = fig.add_subplot(111)
    bp = ax.boxplot(data_plot)
    fig.savefig(file_name, bbox_inches='tight')
    plt.close()

typename and class are interchangeable in the basic case of specifying a template:

template<class T>
class Foo
{
};

and

template<typename T>
class Foo
{
};

are equivalent.

Having said that, there are specific cases where there is a difference between typename and class.

The first one is in the case of dependent types. typename is used to declare when you are referencing a nested type that depends on another template parameter, such as the typedef in this example:

template<typename param_t>
class Foo
{
    typedef typename param_t::baz sub_t;
};

The second one you actually show in your question, though you might not realize it:

template < template < typename, typename > class Container, typename Type >

When specifying a template template, the class keyword MUST be used as above -- it is not interchangeable with typename in this case (note: since C++17 both keywords are allowed in this case).

You also must use class when explicitly instantiating a template:

template class Foo<int>;

I'm sure that there are other cases that I've missed, but the bottom line is: these two keywords are not equivalent, and these are some common cases where you need to use one or the other.

Simply convert boolean field to integer and do a sum. This will work on postgresql :

select sum(myCol::int) from <table name>

Hope that helps!

PDFClown might help, but I would not recommend it for a big or heavy use application.

You should use POST for partial updates.

To update fields for customer 123, make a POST to /customer/123.

If you want to update just the status, you could also PUT to /customer/123/status.

Generally, GET requests should not have any side effects, and PUT is for writing/replacing the entire resource.

This follows directly from HTTP, as seen here: http://en.wikipedia.org/wiki/HTTP_PUT#Request_methods

Check this cool version out. The idea is to implement both String and ErrorType protocols and use the error's rawValue.

enum UserValidationError: String, Error {
  case noFirstNameProvided = "Please insert your first name."
  case noLastNameProvided = "Please insert your last name."
  case noAgeProvided = "Please insert your age."
  case noEmailProvided = "Please insert your email."
}

Usage:

do {
  try User.define(firstName,
                  lastName: lastName,
                  age: age,
                  email: email,
                  gender: gender,
                  location: location,
                  phone: phone)
}
catch let error as User.UserValidationError {
  print(error.rawValue)
  return
}

You can implement your OTF font using @font-face like:

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWeb.otf") format("opentype");
}

@font-face {
    font-family: GraublauWeb;
    font-weight: bold;
    src: url("path/GraublauWebBold.otf") format("opentype");
}

// Edit: OTF now works in most browsers, see comments

However if you want to support a wide variety of browsers i would recommend you to switch to WOFF and TTF font types. WOFF type is implemented by every major desktop browser, while the TTF type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf")  format("truetype");
}

If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:

@font-face {
    font-family: GraublauWeb;
    src: url("webfont.eot"); /* IE9 Compat Modes */
    src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
         url("webfont.woff") format("woff"), /* Modern Browsers */
         url("webfont.ttf")  format("truetype"), /* Safari, Android, iOS */
         url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}

You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:

EOT Browser Support

WOFF Browser Support

TTF Browser Support

I see users in comments wondering how to disable cell editing while allowing row deletion : I managed to do this by setting all columns individually to read only, instead of the DataGrid itself.

<DataGrid IsReadOnly="False">
    <DataGrid.Columns>
        <DataGridTextColumn IsReadOnly="True"/>
        <DataGridTextColumn IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>

Here is my config file. It took some wrestling but now it is working. I am using windows server, msysgit and beyond compare 3 (apparently an x86 version). Youll notice that I dont need to specify any arguments, and I use "path" instead of "cmd".

[user]
        name = PeteW
        email = [email protected]
[diff]
        tool = bc3
[difftool]
        prompt = false
[difftool "bc3"]
        path = /c/Program Files (x86)/Beyond Compare 3/BComp.exe
[merge]
        tool = bc3
[mergetool]
        prompt = false
        keepBackup = false
[mergetool "bc3"]
        path = /c/Program Files (x86)/Beyond Compare 3/BComp.exe
        trustExitCode = true
[alias]
        dt = difftool
        mt = mergetool

From the @param wiki page:

Parameters With Properties

If a parameter is expected to have a particular property, you can document that immediately after the @param tag for that parameter, like so:

 /**
  * @param userInfo Information about the user.
  * @param userInfo.name The name of the user.
  * @param userInfo.email The email of the user.
  */
 function logIn(userInfo) {
        doLogIn(userInfo.name, userInfo.email);
 }

There used to be a @config tag which immediately followed the corresponding @param, but it appears to have been deprecated (example here).

You can include this directly in your buttun. It works very well. I hope it'll be useful for you. onclick="setTimeout('location.href = ../../dashboard.xhtml;', 7000);"

I think you could create a separate css class that you can use in these cases:

.disable-transition {
  -webkit-transition: none;
  -moz-transition: none;
  -o-transition: color 0 ease-in;
  -ms-transition: none;
  transition: none;
}

Then in jQuery you would toggle the class like so:

$('#<your-element>').addClass('disable-transition');

Well, I guess if you need to remove an element you will make a copy of the array despising the element to be excluded.

// inserting some items
void* element_2_remove = getElement2BRemove();

for (int i = 0; i < vector->size; i++){
       if(vector[i]!=element_2_remove) copy2TempVector(vector[i]);
       }

free(vector->items);
free(vector);
fillFromTempVector(vector);
//

Assume that getElement2BRemove(), copy2TempVector( void* ...) and fillFromTempVector(...) are auxiliary methods to handle the temp vector.

I just want to add that this nearly identical post provides the very useful alternative of using an echo pipe if no force or quiet switch is available. For instance, I think it's the only way to bypass the Y/N prompt in this example.

Echo y|NETDOM COMPUTERNAME WorkComp /Add:Work-Comp

In a general sense you should first look at your command switches for /f, /q, or some variant thereof (for example, Netdom RenameComputer uses /Force, not /f). If there is no switch available, then use an echo pipe.

Parent-Child communication in VueJS

Given a root Vue instance is accessible by all descendants via this.$root, a parent component can access child components via the this.$children array, and a child component can access it's parent via this.$parent, your first instinct might be to access these components directly.

The VueJS documentation warns against this specifically for two very good reasons:

• It tightly couples the parent to the child (and vice versa)
• You can't rely on the parent's state, given that it can be modified by a child component.

The solution is to use Vue's custom event interface

The event interface implemented by Vue allows you to communicate up and down the component tree. Leveraging the custom event interface gives you access to four methods:

1. $on() - allows you to declare a listener on your Vue instance with which to listen to events
2. $emit() - allows you to trigger events on the same instance (self)

Example using $on() and $emit():

const events = new Vue({}),_x000D_
    parentComponent = new Vue({_x000D_
      el: '#parent',_x000D_
      ready() {_x000D_
        events.$on('eventGreet', () => {_x000D_
          this.parentMsg = `I heard the greeting event from Child component ${++this.counter} times..`;_x000D_
        });_x000D_
      },_x000D_
      data: {_x000D_
        parentMsg: 'I am listening for an event..',_x000D_
        counter: 0_x000D_
      }_x000D_
    }),_x000D_
    childComponent = new Vue({_x000D_
      el: '#child',_x000D_
      methods: {_x000D_
      greet: function () {_x000D_
        events.$emit('eventGreet');_x000D_
        this.childMsg = `I am firing greeting event ${++this.counter} times..`;_x000D_
      }_x000D_
    },_x000D_
    data: {_x000D_
      childMsg: 'I am getting ready to fire an event.',_x000D_
      counter: 0_x000D_
    }_x000D_

Answer taken from the original post: Communicating between components in VueJS

I use Spring Boot, my solution to the problem was

"src/main/resources/myfile.extension"

Hope it helps someone.

If start time is a datetime type then you can use something like

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime >= '2012-03-08 00:00:00.000' 
AND StartTime <= '2012-03-08 01:00:00.000'

Obviously you would want to use your own values for the times but this should give you everything in that 1 hour period inclusive of both the upper and lower limit.

You can use the GETDATE() function to get todays current date.

Python implementation of the solution. Get the set of the array - This ensures we have unique elements only. Then keep checking until the value is not present in the set - Print the next value as output and return it.

def solution(A):
# write your code in Python 3.6
    a = set(A)
    i = 1
    while True:
        if i in A:
            i+=1
        else:
            return i
    return i
    pass

Best way would be to declare Boolean variable within the code block and return it at end of code, like this:

public boolean Test(){
    boolean booleanFlag= true; 
    if (A>B)
    {booleanFlag= true;}
    else 
    {booleanFlag = false;}
    return booleanFlag;

}

I find this the best way.

You can use canvas’ context.translate & context.rotate to do rotate your image

Here’s a function to draw an image that is rotated by the specified degrees:

function drawRotated(degrees){
    context.clearRect(0,0,canvas.width,canvas.height);

    // save the unrotated context of the canvas so we can restore it later
    // the alternative is to untranslate & unrotate after drawing
    context.save();

    // move to the center of the canvas
    context.translate(canvas.width/2,canvas.height/2);

    // rotate the canvas to the specified degrees
    context.rotate(degrees*Math.PI/180);

    // draw the image
    // since the context is rotated, the image will be rotated also
    context.drawImage(image,-image.width/2,-image.width/2);

    // we’re done with the rotating so restore the unrotated context
    context.restore();
}

Try changing matplotlib backend editing matplotlibrc file located in [python install dir]/matplotlib/mpl-data/matplotlibrc changing The backend parameter from backend: TkAgg to something other like backend: Qt4Aggas described here: http://matplotlib.org/faq/usage_faq.html#what-is-a-backend

You can check if the row exists, and then INSERT or UPDATE, but this guarantees you will be performing two SQL operations instead of one:

1. check if row exists
2. insert or update row

A better solution is to always UPDATE first, and if no rows were updated, then do an INSERT, like so:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'

if @@ROWCOUNT = 0
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')

This will either take one SQL operations, or two SQL operations, depending on whether the row already exists.

But if performance is really an issue, then you need to figure out if the operations are more likely to be INSERT's or UPDATE's. If UPDATE's are more common, do the above. If INSERT's are more common, you can do that in reverse, but you have to add error handling.

BEGIN TRY
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')
END TRY
BEGIN CATCH
  update table1 
  set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
  where id = 'val1'
END CATCH

To be really certain if you need to do an UPDATE or INSERT, you have to do two operations within a single TRANSACTION. Theoretically, right after the first UPDATE or INSERT (or even the EXISTS check), but before the next INSERT/UPDATE statement, the database could have changed, causing the second statement to fail anyway. This is exceedingly rare, and the overhead for transactions may not be worth it.

Alternately, you can use a single SQL operation called MERGE to perform either an INSERT or an UPDATE, but that's also probably overkill for this one-row operation.

Consider reading about SQL transaction statements, race conditions, SQL MERGE statement.

As suggested by Alan, function 'mapply' applies a function to multiple Multiple Lists or Vector Arguments:

mapply(myfun, arg1, arg2)

See man page: https://stat.ethz.ch/R-manual/R-devel/library/base/html/mapply.html

You can simply pass the functions as a list:

In [20]: df.groupby("dummy").agg({"returns": [np.mean, np.sum]})
Out[20]:         
           mean       sum
dummy                    
1      0.036901  0.369012

or as a dictionary:

In [21]: df.groupby('dummy').agg({'returns':
                                  {'Mean': np.mean, 'Sum': np.sum}})
Out[21]: 
        returns          
           Mean       Sum
dummy                    
1      0.036901  0.369012

Best practice is to use an interface to specify the contract and an abstract class as just one implementation thereof. That abstract class can fill in a lot of the boilerplate so you can create an implementation by just overriding what you need to or want to without forcing you to use a particular implementation.

Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-

bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait

Then when this is triggered, as -

subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')

This will be printed only after all the background processes are done.

You can use

$objWorksheet->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
$objWorksheet->getActiveSheet()->getColumnDimension('A')->setWidth(100);

or define auto-size:

$objWorksheet->getRowDimension('1')->setRowHeight(-1);

Bootstrap 4 define a CSS style for the HTML built-in horizontal divider <hr />, so just use it.

You can also customize margin with spacing utilities: mt for margin top, mb for margin bottom and my for margin top and bottom. The integer represent spacing 1 for small margin and 5 for huge margin. Here is an example:

<hr class="mt-2 mb-3"/>
<!-- OR -->
<hr class="my-3"/>
<!-- It's like -->
<hr class="mt-3 mb-3"/>

I used to be using just a div with border-top like:

<div class="border-top my-3"></div>

but it's a silly method to make the work done, and you can have some issues. So just use <hr />.

You can use the % character to 'escape' characters that aren't allowed in URLs. See [RFC 1738].

The easiest way is to create an UIImageView subclass (I have tried it and it's working perfectly on iPhone 7 and XCode 8):

class CIRoundedImageView: UIImageView {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func awakeFromNib() {

        self.layoutIfNeeded()
        layer.cornerRadius = self.frame.height / 2.0
        layer.masksToBounds = true
    }
}

and then you can also set a border:

imageView.layer.borderWidth = 2.0

imageView.layer.borderColor = UIColor.blackColor().CGColor

As the key is needed, the accepted solution doesn't work.

This:

end($array);
return array(key($array) => array_pop($array));

will return exactly as the example in the question.

A solution for me:

$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
   WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {        
   #Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference 

Or use try-catch

try { 

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)

} 
catch {

}

Depending on how it's being used, it might be necessary and even handy. http://php.net/manual/en/language.operators.logical.php

// "||" has a greater precedence than "or"

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

But in most cases it seems like more of a developer taste thing, like every occurrence of this that I've seen in CodeIgniter framework like @Sarfraz has mentioned.

extern "C" doesn't really change the way that the compiler reads the code. If your code is in a .c file, it will be compiled as C, if it is in a .cpp file, it will be compiled as C++ (unless you do something strange to your configuration).

What extern "C" does is affect linkage. C++ functions, when compiled, have their names mangled -- this is what makes overloading possible. The function name gets modified based on the types and number of parameters, so that two functions with the same name will have different symbol names.

Code inside an extern "C" is still C++ code. There are limitations on what you can do in an extern "C" block, but they're all about linkage. You can't define any new symbols that can't be built with C linkage. That means no classes or templates, for example.

extern "C" blocks nest nicely. There's also extern "C++" if you find yourself hopelessly trapped inside of extern "C" regions, but it isn't such a good idea from a cleanliness perspective.

Now, specifically regarding your numbered questions:

Regarding #1: __cplusplus will stay defined inside of extern "C" blocks. This doesn't matter, though, since the blocks should nest neatly.

Regarding #2: __cplusplus will be defined for any compilation unit that is being run through the C++ compiler. Generally, that means .cpp files and any files being included by that .cpp file. The same .h (or .hh or .hpp or what-have-you) could be interpreted as C or C++ at different times, if different compilation units include them. If you want the prototypes in the .h file to refer to C symbol names, then they must have extern "C" when being interpreted as C++, and they should not have extern "C" when being interpreted as C -- hence the #ifdef __cplusplus checking.

To answer your question #3: functions without prototypes will have C++ linkage if they are in .cpp files and not inside of an extern "C" block. This is fine, though, because if it has no prototype, it can only be called by other functions in the same file, and then you don't generally care what the linkage looks like, because you aren't planning on having that function be called by anything outside the same compilation unit anyway.

For #4, you've got it exactly. If you are including a header for code that has C linkage (such as code that was compiled by a C compiler), then you must extern "C" the header -- that way you will be able to link with the library. (Otherwise, your linker would be looking for functions with names like _Z1hic when you were looking for void h(int, char)

5: This sort of mixing is a common reason to use extern "C", and I don't see anything wrong with doing it this way -- just make sure you understand what you are doing.

If your byte array may contain runs of ASCII characters that you'd like to be able to see, you might prefer BAIS (Byte Array In String) format instead of Base64. The nice thing about BAIS is that if all the bytes happen to be ASCII, they are converted 1-to-1 to a string (e.g. byte array {65,66,67} becomes simply "ABC") Also, BAIS often gives you a smaller file size than Base64 (this isn't guaranteed).

After converting the byte array to a BAIS string, write it to JSON like you would any other string.

Here is a Java class (ported from the original C#) that converts byte arrays to string and back.

import java.io.*;
import java.lang.*;
import java.util.*;

public class ByteArrayInString
{
  // Encodes a byte array to a string with BAIS encoding, which 
  // preserves runs of ASCII characters unchanged.
  //
  // For simplicity, this method's base-64 encoding always encodes groups of 
  // three bytes if possible (as four characters). This decision may 
  // unfortunately cut off the beginning of some ASCII runs.

      else {
        sb.append('\b');
        // Do binary encoding in groups of 3 bytes
        for (;; b = get(bytes,i++)) {

What you have from the server is a string like below:

var data = '[{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}]';

Then you can use JSON.parse function to change it to an object. Then you access the category like below:

var dataObj = JSON.parse(data);

console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie

Developers use different editions of the Java platform to create Java programs that run on desktop computers, web browsers, web servers, mobile information devices (such as feature phones), and embedded devices (such as television set-top boxes).

Java Platform, Standard Edition (Java SE): The Java platform for developing applications, which are stand-alone programs that run on desktops. Java SE is also used to develop applets, which are programs that run in web browsers.

Java Platform, Enterprise Edition (Java EE): The Java platform for developing enterprise-oriented applications and servlets, which are server programs that conform to Java EE’s Servlet API. Java EE is built on top of Java SE.

Java Platform, Micro Edition (Java ME): The Java platform for developing MIDlets, which are programs that run on mobile information devices, and Xlets, which are programs that run on embedded devices.

The HttpServletRequest object provides a map of parameters already. See request.getParameterMap() for more details.

Here are a couple dplyr options that keep non-duplicate rows based on columns id and id2:

library(dplyr)                                        
df %>% distinct(id, id2, .keep_all = TRUE)
df %>% group_by(id, id2) %>% filter(row_number() == 1)
df %>% group_by(id, id2) %>% slice(1)

You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.

$data = array(
    array(
        "title" => "Another title",
        "date"  => "Fri, 17 Jun 2011 08:55:57 +0200"
    ),
    array(
        "title" => "My title",
        "date"  => "Mon, 16 Jun 2010 06:55:57 +0200"
    )
);

function sortFunction( $a, $b ) {
    return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);

I had a very related issue but for higher Java versions:

$ ./gradlew clean assemble

... <other normal Gradle output>

Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'.

I noticed that the task succeeded when running using InteliJ. Adding a file (same level as build.gradle) called .java-version solved my issue:

 # .java-version

I would like to point everybody's attention to pathod

With a config (taken from their examples) of 200:b@100:dr you'll get a connection that randomly drops.

The best option according to me is to have key/value pairs file as it could be read from other scripting languages.

Other thing is I would prefer to have an option for comments in the values file - which can be easy achieved with eol option in for /f command.

Here's the example

values file:

;;;;;; file with example values ;;;;;;;;

;; Will be processed by a .bat file
;; ';' can be used for commenting a line

First_Value=value001

;;Do not let spaces arround the equal sign
;; As this makes the processing much easier
;; and reliable

Second_Value=%First_Value%_test

;;as call set will be used in reading script
;; refering another variables will be possible.

Third_Value=Something

;;; end

Reading script:

@echo off

:::::::::::::::::::::::::::::
set "VALUES_FILE=E:\scripts\example.values"
:::::::::::::::::::::::::::::

FOR /F "usebackq eol=; tokens=* delims=" %%# in (
    "%VALUES_FILE%"
) do (
    call set "%%#"
)

echo %First_Value% -- %Second_Value% -- %Third_Value%

Here is how I defined my structure.

type User struct {
    Username string  `json:"username" bson:"username"`
    Email    string  `json:"email" bson:"email"`
    Password *string `json:"password,omitempty" bson:"password"`
    FullName string  `json:"fullname" bson:"fullname"`
}

And inside my function set user.Password = nil for not to be Marshalled.

            #endif /* !INC_OLE1 */
        #endif /* !MAC */
        #include <commdlg.h>
    #endif /* !NOGDI */
#endif /* WIN32_LEAN_AND_MEAN */

if you want to know what each of the headers actually do, typeing the header names into the search in the MSDN library will usually produce a list of the functions in that header file.

Also, from Microsoft's support page:

To speed the build process, Visual C++ and the Windows Headers provide the following new defines:

VC_EXTRALEAN
WIN32_LEAN_AND_MEAN

You can use them to reduce the size of the Win32 header files.

Finally, if you choose to use either of these preprocessor defines, and something you need is missing, you can just include that specific header file yourself. Typing the name of the function you're after into MSDN will usually produce an entry which will tell you which header to include if you want to use it, at the bottom of the page.

$('.clickable').hover(function(){
      $('.selector').stop(true,true).fadeTo( 400 , 0.0, function() {
        $('.selector').css('background-image',"url('assets/img/pic2.jpg')");
        });
    $('.selector').fadeTo( 400 , 1);
},
function(){
      $('.selector').stop(false,true).fadeTo( 400 , 0.0, function() {

Lets assume you want a data frame with the following schema:

root
 |-- k: string (nullable = true)
 |-- v: integer (nullable = false)

You simply define schema for a data frame and use empty RDD[Row]:

import org.apache.spark.sql.types.{
    StructType, StructField, StringType, IntegerType}
import org.apache.spark.sql.Row

val schema = StructType(
    StructField("k", StringType, true) ::
    StructField("v", IntegerType, false) :: Nil)

// Spark < 2.0
// sqlContext.createDataFrame(sc.emptyRDD[Row], schema) 
spark.createDataFrame(sc.emptyRDD[Row], schema)

PySpark equivalent is almost identical:

from pyspark.sql.types import StructType, StructField, IntegerType, StringType

schema = StructType([
    StructField("k", StringType(), True), StructField("v", IntegerType(), False)
])

# or df = sc.parallelize([]).toDF(schema)

# Spark < 2.0 
# sqlContext.createDataFrame([], schema)
df = spark.createDataFrame([], schema)

Using implicit encoders (Scala only) with Product types like Tuple:

import spark.implicits._

Seq.empty[(String, Int)].toDF("k", "v")

or case class:

case class KV(k: String, v: Int)

Seq.empty[KV].toDF

or

spark.emptyDataset[KV].toDF

The source code for clear():

public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
}

The source code for removeAll()(As defined in AbstractCollection):

public boolean removeAll(Collection<?> c) {
    boolean modified = false;
    Iterator<?> e = iterator();
    while (e.hasNext()) {
        if (c.contains(e.next())) {
            e.remove();
            modified = true;
        }
    }
    return modified;
}

clear() is much faster since it doesn't have to deal with all those extra method calls.

And as Atrey points out, c.contains(..) increases the time complexity of removeAll to O(n²) as opposed to clear's O(n).

public class Test1 {
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("helow");
String where="where task in ";
        where+="(";
    //  where+="'task1'";
        int num[]={1,2,3,4};
        for (int i=0;i<num.length+1;i++) {
            if(i==1){
                where +="'"+i+"'";
            }
            if(i>1 && i<num.length)
                where+=", '"+i+"'";
            if(i==num.length){
                System.out.println("This is last number"+i);
            where+=", '"+i+"')";
            }
        }
        System.out.println(where);  
    }
}

This code recursively flattens out JSON objects.

I included my timing mechanism in the code and it gives me 1ms but I'm not sure if that's the most accurate one.

            function flatten(json, flattened, str_key) {
                for (var key in json) {
                  if (json.hasOwnProperty(key)) {
                    if (json[key] instanceof Object && json[key] != "") {
                      flatten(json[key], flattened, str_key + "." + key);
                    } else {
                      flattened[str_key + "." + key] = json[key];
                    }
                  }
                }
            }

        var flattened = {};
        console.time('flatten'); 
        flatten(new_json, flattened, "");
        console.timeEnd('flatten');

        for (var key in flattened){
          console.log(key + ": " + flattened[key]);
        }

To remove you can use this directly:

getSupportFragmentManager().beginTransaction().remove(fragment).
                            commitAllowingStateLoss();

fragment is the fragment you want to remove.

You might consider writing an iterator instead, which allows you to use normal 'for' loop syntax like '++'. I searched and found a similar question answered here on StackOverflow which gives pointers on making DateTime iterable.

Anything after the "vmargs" is taken to be vm arguments. Just make sure it's before that, which is the last piece in eclipse.ini.

This isn't specific to Android Studio, but a generic behaviour with Intellij's IDEA.

Go to: Preferences > Version Control > GitHub

Also note that you don't need the github integration: the standard git functions should be enough (VCS > Git, Tool Windows > Changes)

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

When I stumble upon this issue, I just pass the objects to the inner class through the constructor. If I need to pass primitives or immutable objects (as in this case), a wrapper class is needed.

Edit: Actually, I don't use an anonymous class at all, but a proper subclass:

public class PriceData {
        private double lastPrice = 0;
        private double price = 0;

        public void setlastPrice(double lastPrice) {
            this.lastPrice = lastPrice;
        }

        public double getLastPrice() {
            return lastPrice;
        }

        public void setPrice(double price) {
            this.price = price;
        }

        public double getPrice() {
            return price;
        }
    }

    public class PriceTimerTask extends TimerTask {
        private PriceData priceData;
        private Price priceObject;

        public PriceTimerTask(PriceData priceData, Price priceObject) {
            this.priceData = priceData;
            this.priceObject = priceObject;
        }

        public void run() {
            priceData.setPrice(priceObject.getNextPrice(lastPrice));
            System.out.println();
            priceData.setLastPrice(priceData.getPrice());

        }
    }

    public static void main(String args[]) {

        int period = 2000;
        int delay = 2000;

        PriceData priceData = new PriceData();
        Price priceObject = new Price();

        Timer timer = new Timer();

        timer.scheduleAtFixedRate(new PriceTimerTask(priceData, priceObject), delay, period);
    }

I initially went into the SDK Manager and updated all that it had set to update.

I also added in the SDK version for the version of Android I had on the Droid I had...Version 2.3.4(10)

I don't think that really fixed anything, and after a Android Studio restart as recommended after the SDK installs, I changed the minSdkVersion to 8 in the build.gradle file

I was then able to download the application to my Droid.

defaultConfig {
    applicationId "com.cmcjr.chuck.droid_u"
    minSdkVersion 8
    targetSdkVersion 20
    versionCode 1
    versionName "1.0"
}

This is Android Studio installed on Ubuntu 12.04

If you want to downgrade php version, just simply edit yout .htaccess file. Like you want to downgrade any php version to 5.6, just add this into .htaccess file

<FilesMatch "\.(php4|php5|php7|php3|php2|php|phtml)$">  
etHandler application/x-lsphp56
</FilesMatch>

Correct way (if you are not trying to reset the value of the hidden_field input) is:

f.hidden_field :method, :value => value_of_the_hidden_field_as_it_comes_through_in_your_form

Where :method is the method that when called on the object results in the value you want

So following the example above:

= simple_form_for @movie do |f|
  = f.hidden :title, "some value"
  = f.button :submit

The code used in the example will reset the value (:title) of @movie being passed by the form. If you need to access the value (:title) of a movie, instead of resetting it, do this:

= simple_form_for @movie do |f|
  = f.hidden :title, :value => params[:movie][:title]
  = f.button :submit

Again only use my answer is you do not want to reset the value submitted by the user.

I hope this makes sense.

Elastic Beanstalk can bind a single EC2 keypair to an instance profile. A manual solution to have multiple users ssh into EBS is to add their public keys in authorized_keys file.

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'

We have an app in Google Play and the App Store that will scan barcodes into a web site. The app is called Scan to Web. http://berrywing.com/scantoweb.html

You can even embed a link or button to start the scanner yourself within your web page.

<a href="bwstw://startscanner">Link to start scanner</a>

The developer documentation website for the app covers how to use the app and use JavaScript for processing the barcode scan. http://berrywing.com/scantoweb/#htmlscanbutton

Regarding Chrome, checkout the monitorEvents() via the command line API.

• Open the console via Menu > Tools > JavaScript Console.

• Enter monitorEvents(window);

• View the console flooded with events

   ...
   mousemove MouseEvent {dataTransfer: ...}
   mouseout MouseEvent {dataTransfer: ...}
   mouseover MouseEvent {dataTransfer: ...}
   change Event {clipboardData: ...}
   ...
  

There are other examples in the documentation. I'm guessing this feature was added after the previous answer.

One thing I would add here is that the at function on a dataframe is much faster particularly if you are doing a lot of assignments of individual (not slice) values.

df.at[index, 'col_name'] = x

In my experience I have gotten a 20x speedup. Here is a write up that is Spanish but still gives an impression of what's going on.

I got the same problem also. Here's what I did:

If you're already done granting the user/group the rights to use the profile name.

1. Go to the configuration Wizard of Database Mail
2. Tick Manage profile security
3. On public profiles tab, check your profile name
4. On private profiles tab, select NT AUTHORITY\NETWORK SERVICE for user name and check your profile name
5. Do #4 this time for NT AUTHORITY\SYSTEM user name
6. Click Next until Finish.

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

Try changing this:

new_DF<-dplyr::filter(DF,is.na(Var2)) 

I had this error as well. I triple checked that names were correct.

However I got this error simply because I was not terminating the script tag.

<template>
  <div>
    <p>My Form</p>
    <PageA></PageA>        
  </div>
</template>

<script>
import PageA from "./PageA.vue"

export default {
  name: "MyForm",
  components: {
    PageA
  }
}

Notice there is no </script> at the end.

So be sure to double check this.

This can be caused by the use of a proxy as well. Check if you have proxy definitions in the /etc/environment file:

cat /etc/environment

If you have anything with http_proxy or https_proxy upper or lower case then unset each of them.

For anyone looking for an answer in 2020. This worked for me.

In Views:

 class InstancesView(generic.ListView):
        model = AlarmInstance
        context_object_name = 'settings_context'
        queryset = Group.objects.all()
        template_name = 'insta_list.html'

        @register.filter
        def filter_unknown(self, aVal):
            result = aVal.filter(is_known=False)
            return result

        @register.filter
        def filter_known(self, aVal):
            result = aVal.filter(is_known=True)
            return result

In template:

{% for instance in alarm.qar_alarm_instances|filter_unknown:alarm.qar_alarm_instances %}

In pseudocode:

For each in model.child_object|view_filter:filter_arg

Hope that helps.

You could add google() to repositories block

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://github.com/uPhyca/stetho-realm/raw/master/maven-repo'

        }
        maven {
            url "https://jitpack.io"
        }
        google()
    }
}

Another option altogether is to detach the database via Management Studio. Then simply delete the log file, or rename it and delete later.

Back in Management Studio attach the database again. In the attach window remove the log file from list of files.

The DB attaches and creates a new empty log file. After you check everything is all right, you can delete the renamed log file.

You probably ought not use this for production databases.

sum(case when c.runstatus = 'Succeeded' then 1 else 0 end) as Succeeded, 
sum(case when c.runstatus = 'Failed' then 1 else 0 end) as Failed, 
sum(case when c.runstatus = 'Cancelled' then 1 else 0 end) as Cancelled, 

the issue here is that without the else statement, you are bound to receive a Null when the run status isn't the stated status in the column description. Adding anything to Null will result in Null, and that is the issue with this query.

Good Luck!

So basically you want to convert a String into an Integer right! here is what I mostly use and that is also mentioned in official documentation..

fn main() {

    let char = "23";
    let char : i32 = char.trim().parse().unwrap();
    println!("{}", char + 1);

}

This works for both String and &str Hope this will help too.

Are they the home directories of users in /etc/passwd? Services like postgres, sendmail, apache, etc., create system users that have home directories just like normal users.

Your problem is that excel does not recognize your text strings of "mm/dd/yyyy" as date objects in it's internal memory. Therefore when you create pivottable it doesn't consider these strings to be dates.

You'll need to first convert your dates to actual date values before creating the pivottable. This is a good resource for that: http://office.microsoft.com/en-us/excel-help/convert-dates-stored-as-text-to-dates-HP001162867.aspx

In your spreadsheet I created a second date column in B with the formula =DATEVALUE(A2). Creating a pivot table with this new date column and Count of Sales then sorts correctly in the pivot table (option becomes Sort Oldest to Newest instead of Sort A to Z).

It should be like

params.permit(:id => [])

Also since rails version 4+ you can use:

params.permit(id: [])

In addition to the suggestions in this thread, I wanted to mention that if you need to return dot files as well (.gitignore, etc), with Dir.glob you would need to include a flag as so: Dir.glob("/path/to/dir/*", File::FNM_DOTMATCH) By default, Dir.entries includes dot files, as well as current a parent directories.

For anyone interested, I was curious how the answers here compared to each other in execution time, here was the results against deeply nested hierarchy. The first three results are non-recursive:

       user     system      total        real

 12.178823  19.577409  31.756232 ( 31.767093)

These were generated with the following benchmarking script:

require 'benchmark'
base_dir = "/path/to/dir/"
n = 100
Benchmark.bm do |x|
  x.report("Dir[*]:") do
    i = 0

      def walk_dir(dir, result)
        Dir.entries(dir).each do |file|
          next if file == ".." || file == "."

          path = File.join(dir, file)
          if Dir.exist?(path)
            walk_dir(path, result)
          else
            result << file
          end
        end
      end
      result = Array.new
      walk_dir(base_dir, result)
      i = i + result.length
    end
    puts " (#{i} files stepped over #{n} iterations)"
  end
  x.report("Dir.glob(**/*, File::FNM_DOTMATCH):") do
    i = 0
    n.times do
      i = i + Dir.glob("#{base_dir}**/*", File::FNM_DOTMATCH).select {|f| !File.directory? f}.length
    end
    puts " (#{i} files stepped over #{n} iterations)"
  end
end

The differences in file counts are due to Dir.entries including hidden files by default. Dir.entries ended up taking a bit longer in this case due to needing to rebuild the absolute path of the file to determine if a file was a directory, but even without that it was still taking consistently longer than the other options in the recursive case. This was all using ruby 2.5.1 on OSX.

Maybe an old topic but if someone needs further help with this do the following for example (this puts the text in middle line of image if it has larger height then the text).

HTML:

<div class="row display-table">
    <div class="col-xs-12 col-sm-4 display-cell">
        img
    </div>
    <div class="col-xs-12 col-sm-8 display-cell">
        text
    </div>
</div>

CSS:

.display-table{
    display: table;
    table-layout: fixed;
}

.display-cell{
    display: table-cell;
    vertical-align: middle;
    float: none;
}

The important thing that I missed out on was "float: none;" since it got float left from bootstrap col attributes.

Cheers!

I noticed some issues with this that might be useful for someone just starting, or a somewhat inexperienced user, to know. First...

CD /D "C:\Documents and Settings\%username%\Start Menu\Programs\"

two things one is that a /D after the CD may prove to be useful in making sure the directory is changed but it's not really necessary, second, if you are going to pass this from user to user you have to add, instead of your name, the code %username%, this makes the code usable on any computer, as long as they have your setup.exe file in the same location as you do on your computer. of course making sure of that is more difficult. also...

start \\filer\repo\lab\"software"\"myapp"\setup.exe

the start code here, can be set up like that, but the correct syntax is

start "\\filter\repo\lab\software\myapp\" setup.exe

This will run: setup.exe, located in: \filter\repo\lab...etc.\

Here's how you can fix it on Windows: https://gist.github.com/867550 (created by Fletcher Nichol)

Excerpt:

The Manual Way (Boring)

Download the cacert.pem file from http://curl.haxx.se/ca/cacert.pem. Save this file to C:\RailsInstaller\cacert.pem.

Now make ruby aware of your certificate authority bundle by setting SSL_CERT_FILE. To set this in your current command prompt session, type:

set SSL_CERT_FILE=C:\RailsInstaller\cacert.pem

To make this a permanent setting, add this in your control panel.

Try this

 <head>
 <style type ="text/css" >
   .footer{ 
       position: fixed;     
       text-align: center;    
       bottom: 0px; 
       width: 100%;
   }  
</style>
</head>
<body>
    <div class="footer">All Rights Reserved</div>
</body>

To update component

 @Injectable()
    export class LoginService{
    private isUserLoggedIn: boolean = false;

    public setLoggedInUser(flag) { // you need set header flag true false from other components on basis of your requirements, header component will be visible as per this flag then
    this.isUserLoggedIn= flag;
    }


public getUserLoggedIn(): boolean {
return this.isUserLoggedIn;
}

Login Component ts
            Login Component{
             constructor(public service: LoginService){}

public login(){
service.setLoggedInUser(true);
}
            }
Inside Header component

 Header Component ts
        HeaderComponent {
         constructor(public service: LoginService){}

         public getUserLoggedIn(): boolean { return this.service.getUserLoggedIn()}
        }

template of header component: Check for user sign in here

<button *ngIf="getUserLoggedIn()">Sign Out</button>
<button *ngIf="!getUserLoggedIn()">Sign In</button>

You can use many approach like show hide using ngIf

App Component ts
AppComponent {
 public showHeader: boolean = true;
}
App Component html
<div *ngIf='showHeader'> // you show hide on basis of this ngIf and header component always get visible with it's lifecycle hook ngOnInit() called all the time when it get visible
<app-header></app-header>
</div>
<router-outlet></router-outlet>
<app-footer></app-footer>

You can also use service

@Injectable()
export class AppService {
private showHeader: boolean = false;

public setHeader(flag) { // you need set header flag true false from other components on basis of your requirements, header component will be visible as per this flag then
this.showHeader = flag;
}

public getHeader(): boolean {
return this.showHeader;
}
}

App Component.ts
    AppComponent {
     constructor(public service: AppService){}
    }

App Component.html
    <div *ngIf='service.showHeader'> // you show hide on basis of this ngIf and header component always get visible with it's lifecycle hook ngOnInit() called all the time when it get visible
    <app-header></app-header>
    </div>
    <router-outlet></router-outlet>
    <app-footer></app-footer>

You can use Environment.Exit(0) and Application.Exit.

Environment.Exit(): terminates this process and gives the underlying operating system the specified exit code.

Yocoder is right,

Inside the DataTemplate, your DataContext is set to the Rule its currently handling..

To access the parents DataContext, you can also consider using a RelativeSource in your binding:

<TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ____Your Parent control here___ }}, Path=DataContext.SelectedRule.Name}" />

More info on RelativeSource can be found here:

http://msdn.microsoft.com/en-us/library/system.windows.data.relativesource.aspx

I get this every time I want to create an application in VC++.

Right-click the project, select Properties then under 'Configuration properties | C/C++ | Code Generation', select "Multi-threaded Debug (/MTd)" for Debug configuration.

Note that this does not change the setting for your Release configuration - you'll need to go to the same location and select "Multi-threaded (/MT)" for Release.

Here's an approach based on the idea of coercing the input to a number or string by adding zero or the null string, and then do a typed equality comparison.

function is_number(x) { return x === x+0;  }
function is_string(x) { return x === x+""; }

For some unfathomable reason, x===x+0 seems to perform better than x===+x.

Are there any cases where this fails?

In the same vein:

function is_boolean(x) { return x === !!x; }

This appears to be mildly faster than either x===true || x===false or typeof x==="boolean" (and much faster than x===Boolean(x)).

Then there's also

function is_regexp(x)  { return x === RegExp(x); }

All these depend on the existence of an "identity" operation particular to each type which can be applied to any value and reliably produce a value of the type in question. I cannot think of such an operation for dates.

For NaN, there is

function is_nan(x) { return x !== x;}

This is basically underscore's version, and as it stands is about four times faster than isNaN(), but the comments in the underscore source mention that "NaN is the only number that does not equal itself" and adds a check for _.isNumber. Why? What other objects would not equal themselves? Also, underscore uses x !== +x--but what difference could the + here make?

Then for the paranoid:

function is_undefined(x) { return x===[][0]; }

or this

function is_undefined(x) { return x===void(0); }

Maybe powershell -Command "Get-AppLockerFileInformation....."

Take a look at powershell /?

I faced the same issue. I rectified it by going to the particular client under the realm respectively therein redirect URL add * after your complete URL.

There is a difference.

When the ^ character appears outside of [] matches the beginning of the line (or string). When the ^ character appears inside the [], it matches any character not appearing inside the [].

Angular no longer supports --env instead you have to use

ng serve -c dev

for development environment and,

ng serve -c prod 

for production.

NOTE: -c or --configuration

For JDK 1.3 or earlier :

-Xnoagent -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For JDK 1.4

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For newer JDK :

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=6006

Please change the port number based on your needs.

From java technotes

From 5.0 onwards the -agentlib:jdwp option is used to load and specify options to the JDWP agent. For releases prior to 5.0, the -Xdebug and -Xrunjdwp options are used (the 5.0 implementation also supports the -Xdebug and -Xrunjdwp options but the newer -agentlib:jdwp option is preferable as the JDWP agent in 5.0 uses the JVM TI interface to the VM rather than the older JVMDI interface)

One more thing to note, from JVM Tool interface documentation:

JVM TI was introduced at JDK 5.0. JVM TI replaces the Java Virtual Machine Profiler Interface (JVMPI) and the Java Virtual Machine Debug Interface (JVMDI) which, as of JDK 6, are no longer provided.

If SESSION_START_DATE_TIME is of type TIMESTAMP you may want to try using the SQL function TO_TIMESTAMP. Here is an example:

     SQL> CREATE TABLE t (ts TIMESTAMP);

     Table created.

     SQL> INSERT INTO t
       2       VALUES (
       3                 TO_TIMESTAMP (
       4                    '1/12/2012 5:03:27.221008 PM'
       5                   ,'mm/dd/yyyy HH:MI:SS.FF AM'
       6                 )
       7              );

     1 row created.

     SQL> SELECT *
       2    FROM t
       3   WHERE ts =
       4            TO_TIMESTAMP (
       5               '1/12/2012 5:03:27.221008 PM'
       6              ,'mm/dd/yyyy HH:MI:SS.FF AM'

There might be some edge case where you have a vector access inside an inline function inside an inline function, where you've gone beyond what the compiler will inline and it will force a function call. That would be so rare as to not be worth worrying about - in general I would agree with litb.

I'm surprised nobody has mentioned this yet - don't worry about performance until it has been proven to be a problem, then benchmark.

First save all IDs and alter them programmatically to the values you wan't, then remove them from database and then insert them again using something similar:

use [Name.Database]
go
set identity_insert [Test] ON
insert into [dbo].[Test]
           ([Id])
     VALUES
           (2)
set identity_insert [Test] OFF

For bulk insert use:

use [Name.Database]
go
set identity_insert [Test] ON
BULK INSERT [Test]
FROM 'C:\Users\Oscar\file.csv'
WITH (FIELDTERMINATOR = ';',
      ROWTERMINATOR = '\n',
      KEEPIDENTITY)
set identity_insert [Test] OFF

Sample data from file.csv:

2;
3;
4;
5;
6;

If you don't set identity_insert to off you will get the following error:

Cannot insert explicit value for identity column in table 'Test' when IDENTITY_INSERT is set to OFF.

Article and Section are both semantic elements of HTML5. Section is block level generic section of a webpage, but relevant to our webpage content. Article is also block level, but article refers to an individual blog post, a comment, of a webpage.

Both Article and Section should include an heading elements h2-h6.

For a blog post, use following syntax for article and section.

<article role="main">
         <h1>Heading 1</h1>
         <p>Article Description</p>
         <section id="sec1">
                <h2>Section Heading</h2>
                <p>Section Description</p>
         </section>
         <section id="sec2">
                <h2>Section Heading</h2>
                <p>Section Description</p>
         </section>
</article>

If you set position to other value than static but your element's z-index still doesn't seem to work, it may be that some parent element has z-index set.

The stacking contexts have hierarchy, and each stacking context is considered in the stacking order of the parent's stacking context.

So with following html

div { border: 2px solid #000; width: 100px; height: 30px; margin: 10px; position: relative; background-color: #FFF; }_x000D_
#el3 { background-color: #F0F; width: 100px; height: 60px; top: -50px; }

<div id="el1" style="z-index: 5"></div>_x000D_
<div id="el2" style="z-index: 3">_x000D_
  <div id="el3" style="z-index: 8"></div>_x000D_
</div>

no matter how big the z-index of el3 will be set, it will always be under el1 because it's parent has lower stacking context. You can imagine stacking order as levels where stacking order of el3 is actually 3.8 which is lower than 5.

If you want to check stacking contexts of parent elements, you can use this:

var el = document.getElementById("#yourElement"); // or use $0 in chrome;
do {
    var styles = window.getComputedStyle(el);
    console.log(styles.zIndex, el);
} while(el.parentElement && (el = el.parentElement));

There is a great article about stacking contexts on MDN

It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult is generic, however you can determine the exact issue catching HttpRequestException and then inspecting InnerException: if it's a WebException then you can check the WebException.Status property, for example WebExceptionStatus.NameResolutionFailure should indicate a DNS resolution problem.

It may happen, there isn't much you can do.

What I'd suggest to always wrap that (network related) code in a loop with a try/catch block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
    using (var client = new HttpClient()) {
        for (int i=1; i <= NumberOfRetries; ++i) {
            try {
                return await client.GetAsync(url); 
            }
            catch (Exception e) when (i < NumberOfRetries) {
                await Task.Delay(DelayOnRetry);
            }
        }
    }
}

Adding or removing constraints during runtime is a heavyweight operation that can affect performance. However, there is a simpler alternative.

For the view you wish to hide, set up a width constraint. Constrain the other views with a leading horizontal gap to that view.

To hide, update the .constant of the width constraint to 0.f. The other views will automatically move left to assume position.

See my other answer here for more details:

How to change label constraints during runtime?

Take a look at the domReady script that allows setting up of multiple functions to execute when the DOM has loaded. It's basically what the Dom ready does in many popular JavaScript libraries, but is lightweight and can be taken and added at the start of your external script file.

Example usage

// add reference to domReady script or place 
// contents of script before here

function codeAddress() {

}

domReady(codeAddress);

I would recommend installing your node.js app as a Windows service, and then set the service to run at startup. That should make it a bit easier to control the startup action by using the Windows Services snapin rather than having to add or remove batch files in the Startup folder.

Another service-related question in Stackoverflow provided a couple of (apprently) really good options. Check out How to install node.js as a Windows Service. node-windows looks really promising to me. As an aside, I used similar tools for Java apps that needed to run as services. It made my life a whole lot easier. Hope this helps.

My variant on printing the parent process:

ps -p $$ | awk '$1 == PP {print $4}' PP=$$

Don't run unnecessary applications when AWK can do it for you.

You get the integer limits in <limits.h> or <climits>. Floating point characteristics are defined in <float.h> for C. In C++, the preferred version is usually std::numeric_limits<double>::max() (for which you #include <limits>).

As to your original question, if you want a larger integer type than long, you should probably consider long long. This isn't officially included in C++98 or C++03, but is part of C99 and C++11, so all reasonably current compilers support it.

This works — it isn't what I'd use, but it 'works'. Let's create a script teredo to set the environment variable TEREDO_WORMS:

#!/bin/ksh
export TEREDO_WORMS=ukelele
exec $SHELL -i

It will be interpreted by the Korn shell, exports the environment variable, and then replaces itself with a new interactive shell.

Before running this script, we have SHELL set in the environment to the C shell, and the environment variable TEREDO_WORMS is not set:

% env | grep SHELL
SHELL=/bin/csh
% env | grep TEREDO
%

When the script is run, you are in a new shell, another interactive C shell, but the environment variable is set:

% teredo
% env | grep TEREDO
TEREDO_WORMS=ukelele
%

When you exit from this shell, the original shell takes over:

% exit
% env | grep TEREDO
%

The environment variable is not set in the original shell's environment. If you use exec teredo to run the command, then the original interactive shell is replaced by the Korn shell that sets the environment, and then that in turn is replaced by a new interactive C shell:

% exec teredo
% env | grep TEREDO
TEREDO_WORMS=ukelele
%

If you type exit (or Control-D), then your shell exits, probably logging you out of that window, or taking you back to the previous level of shell from where the experiments started.

The same mechanism works for Bash or Korn shell. You may find that the prompt after the exit commands appears in funny places.

Note the discussion in the comments. This is not a solution I would recommend, but it does achieve the stated purpose of a single script to set the environment that works with all shells (that accept the -i option to make an interactive shell). You could also add "$@" after the option to relay any other arguments, which might then make the shell usable as a general 'set environment and execute command' tool. You might want to omit the -i if there are other arguments, leading to:

#!/bin/ksh
export TEREDO_WORMS=ukelele
exec $SHELL "${@-'-i'}"

The "${@-'-i'}" bit means 'if the argument list contains at least one argument, use the original argument list; otherwise, substitute -i for the non-existent arguments'.

DECLARE @StartTime datetime
DECLARE @EndTime datetime

 -- Write Your Query


SELECT @EndTime=GETDATE()

--This will return execution time of your query
SELECT DATEDIFF(MS,@StartTime,@EndTime) AS [Duration in millisecs]

Relative Paths

A relative path assumes that the file is on the current server. Using relative paths allows you to construct your site offline and fully test it before uploading it.

For example:

php/webct/itr/index.php

.

Absolute Paths

An absolute path refers to a file on the Internet using its full URL. Absolute paths tell the browser precisely where to go.

For example:

http://www.uvsc.edu/disted/php/webct/itr/index.php

Absolute paths are easier to use and understand. However, it is not good practice on your own website. For one thing, using relative paths allows you to construct your site offline and fully test it before uploading it. If you were to use absolute paths you would have to change your code before uploading it in order to get it to work. This would also be the case if you ever had to move your site or if you changed domain names.
