1. https://pypi.python.org/pypi/openpyxl download zip file and unzip it on local system.
2. go to openpyxl folder where setup.py is present.
3. open command prompt under the same path.
4. Run a command: python setup.py install
5. It will install openpyxl.

You can use this javascript plugin

It can get a large list of information for you about mobiles and desktop machines including the uuid for example

var uuid = new DeviceUUID().get();

You did not assign the "linux" to the question but you mentioned "Linux top". And thus this might be helpful:

Use the small Linux tool threadcpu to identify the most cpu using threads. It calls jstack to get the thread name. And with "sort -n" in pipe you get the list of threads ordered by cpu usage.

More details can be found here: http://www.tuxad.com/blog/archives/2018/10/01/threadcpu_-_show_cpu_usage_of_threads/index.html

And if you still need more details then create a thread dump or run strace on the thread.

PHP comes with two native functions to show which config file is loaded :

• php_ini_loaded_file return the loaded ini file
• php_ini_scanned_files return a list of .ini files parsed from the additional ini dir

Depending on your setup, Apache and CLI might use different ini files. Here are the two solutions :

Apache :

Just add the following in a php file and open it in your browser

print php_ini_loaded_file();
print_r(php_ini_scanned_files());

CLI :

Copy-paste in your terminal :

php -r 'print php_ini_loaded_file(); print_r(php_ini_scanned_files());'

IMHO, there is not much difference in case of web application if you look at it from the angle of responsibility assignment. However, keep the clarity in the layer. Keep anything purely for the presentation purpose in the presentation layer, like the control and code specific to the web controls. Just keep your entities in the business layer and all features (like add, edit, delete) etc in the business layer. However rendering them onto the browser to be handled in the presentation layer. For .Net, the ASP.NET MVC pattern is very good in terms of keeping the layers separated. Look into the MVC pattern.

A good documentation about WebEngines especially webKit and its developers you can read at: WebKit

Also when I hit the post(Config.getURL("login"), values) the app seems to pause for a while (seems weird - thought the idea behind a service was that it runs on a different thread!)

No you have to create a thread yourself, a Local service runs in the UI thread by default.

Have you looked at easygui?

import easygui

easygui.msgbox("This is a message!", title="simple gui")

First, create the new branch you would like to set as your default, for example:

$>git branch main

Next, push that branch to the origin:

$>git push origin main

Now when you login to your GitHub account, you can go to your repository and choose Settings>Default Branch and choose "main."

Then, if you so choose, you can delete the master branch:

$>git push origin :master

In Command Prompt, you can use the command telnet.. For Example, to connect to IP 192.168.10.1 with port 80,

telnet 192.168.10.1 80

To enable telnet in Windows 7 and above click. From the linked article, enable telnet through control panel -> programs and features -> windows features -> telnet client, or just run this in an admin prompt:

dism /online /Enable-Feature /FeatureName:TelnetClient

this.print(false);

I tried this in Chrome, Firefox and IE. It works only in Firefox and IE, it uses the default printer (with default print settings) and only works when I render a PDF (I use Foxit Reader with Safe Reading Mode disabled). Chrome shows the print dialog, also the other browsers when I render an HTML page.

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

In my case, this jQuery JavaScript solved the problem

jQuery(function() {
            jQuery("form.myform").submit(function(event) {
               event.preventDefault();
               return false;
            });
}

Here comes another vote in favor of PHPKB knowledge base software. We came to know about PHPKB from this post on StackOverflow and bought it as recommended by Julien and Ricardo. I am glad to inform that it was a right decision. Although we had to get certain features customized according to our needs but their support team exceeded our expectations. So, I just thought of sharing the news here. We are fully satisfied with PHPKB knowledge base software.

There is no need to use angular http, you can get with js native functions

// you will ned this function to fetch the image blob._x000D_
async function getImage(url, fileName) {_x000D_
     // on the first then you will return blob from response_x000D_
    return await fetch(url).then(r => r.blob())_x000D_
    .then((blob) => { // on the second, you just create a file from that blob, getting the type and name that intend to inform_x000D_
         _x000D_
        return new File([blob], fileName+'.'+   blob.type.split('/')[1]) ;_x000D_
    });_x000D_
}_x000D_
_x000D_
// example url_x000D_
var url = 'https://img.freepik.com/vetores-gratis/icone-realista-quebrado-vidro-fosco_1284-12125.jpg';_x000D_
_x000D_
// calling the function_x000D_
getImage(url, 'your-name-image').then(function(file) {_x000D_
_x000D_
    // with file reader you will transform the file in a data url file;_x000D_
    var reader = new FileReader();_x000D_
    reader.readAsDataURL(file);_x000D_
    reader.onloadend = () => {_x000D_
    _x000D_
    // just putting the data url to img element_x000D_
        document.querySelector('#image').src = reader.result ;_x000D_
    }_x000D_
})

<img src="" id="image"/>

Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes. Quoting from the documentation for __dict__

A dictionary or other mapping object used to store an object's (writable) attributes.

Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:

def func():
    pass

func.temp = 1

print(func.__dict__)

class TempClass:
    a = 1
    def temp_function(self):
        pass

print(TempClass.__dict__)

will output

{'temp': 1}
{'__module__': '__main__', 
 'a': 1, 
 'temp_function': <function TempClass.temp_function at 0x10a3a2950>, 
 '__dict__': <attribute '__dict__' of 'TempClass' objects>, 
 '__weakref__': <attribute '__weakref__' of 'TempClass' objects>, 
 '__doc__': None}

Google changed their policies last month regarding auto-play inside Chrome. Please see this announcement.

They do, however, allow auto-play if you are embedding a video and it is muted. You can add the muted property and it should allow the video to start playing.

<video autoplay controls muted>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
  Your browser does not support the video tag.
</video>

Transposing the columns like that is a job for zip:

>>> a = [['a', 'b', 'c'], ['aaaaaaaaaa', 'b', 'c'], ['a', 'bbbbbbbbbb', 'c']]
>>> list(zip(*a))
[('a', 'aaaaaaaaaa', 'a'), ('b', 'b', 'bbbbbbbbbb'), ('c', 'c', 'c')]

To find the required length of each column, you can use max:

>>> trans_a = zip(*a)
>>> [max(len(c) for c in b) for b in trans_a]
[10, 10, 1]

Which you can use, with suitable padding, to construct strings to pass to print:

>>> col_lenghts = [max(len(c) for c in b) for b in trans_a]
>>> padding = ' ' # You might want more
>>> padding.join(s.ljust(l) for s,l in zip(a[0], col_lenghts))
'a          b          c'

you need switch into another branch and try the same.

git branch -d

length of string ==how many bits that string having, size==size of those bits, In strings both are same if the editor allocates size of character is 1 byte

My 2 cents for golfers:

b="1,2,3,4".split`,`.map(x=>+x)

backquote is string litteral so we can omit the parenthesis (because of the nature of split function) but it is equivalent to split(','). The string is now an array, we just have to map each value with a function returning the integer of the string so x=>+x (which is even shorter than the Number function (5 chars instead of 6)) is equivalent to :

function(x){return parseInt(x,10)}// version from techfoobar
(x)=>{return parseInt(x)}         // lambda are shorter and parseInt default is 10
(x)=>{return +x}                  // diff. with parseInt in SO but + is better in this case
x=>+x                             // no multiple args, just 1 function call

I hope it is a bit more clear.

If we have this variables:

var counter int = 5
var message string  = "Hello"
var factor float32 = 4.2
var enabled bool = false

1: fmt.Printf %T format : to use this feature you should import "fmt"

fmt.Printf("%T \n",factor )   // factor type: float32

2: reflect.TypeOf function : to use this feature you should import "reflect"

fmt.Println(reflect.TypeOf(enabled)) // enabled type:  bool

3: reflect.ValueOf(X).Kind() : to use this feature you should import "reflect"

fmt.Println(reflect.ValueOf(counter).Kind()) // counter type:  int

You can try this library. This is a wrapper for android default snackbar. https://github.com/ChathuraHettiarachchi/CSnackBar

Snackbar.with(this,null)
    .type(Type.SUCCESS)
    .message("Profile updated successfully!")
    .duration(Duration.SHORT)
    .show();

This contains multiple types of snackbar and even a customview intergrated snackbar

something like this

try 
{
  ...
}
catch (FooException e) 
{
  throw e;
}
catch (Exception e)
{
  ...
}

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

HTTP version 1.1 added a special HTTP method, CONNECT - intended to create the SSL tunnel, including the necessary protocol handshake and cryptographic setup.
The regular requests thereafter all get sent wrapped in the SSL tunnel, headers and body inclusive.

Adding another "Same symptoms, but different solution" response, just in case somebody is having the same problem, but none of the common solutions are working.

In my case, I had an app that started development prior to the instruction of asset catalogs and the flexibility in icon naming conventions, but was first submitted to the store after the transition. To resolve the issue I had to:

1. Delete all the "icon related" lines from the Info.plist
2. Switch back to "Don't use asset catalogs" for both AppIcons and LaunchImages
3. Switch back to asset catalogs for AppIcons and LaunchImages
4. Re-drag&drop the image files into the appropriate locations.

Starting from Bootstrap v4 you can simply add the following to your div class attribute: mt-2 (margin top 2)

<div class="mt-2 col-md-12">
        This will have a two-point top margin!
</div>

More examples are given in the docs: Bootstrap v4 docs

What kind of problem do you get with jregex? It worked well for me under java5 and java6.

Jregex does the job well (even if the last version is from 2002), unless you want to wait for javaSE 7.

npm install typescript@">=3.1.1 <3.3.0" --save-dev --save-exact
rm -rf node_modules
npm install

For me, classpath entry in .classpath file isn't pointing to the right location. After modifying it to <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/> fixed the issue

Use --build-arg with each argument.

If you are passing two argument then add --build-arg with each argument like:

docker build \
-t essearch/ess-elasticsearch:1.7.6 \
--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .

Suresh, you don't need use anything in your codes. What you need is just something like this:

.others {_x000D_
    color:black_x000D_
}

<select id="select">_x000D_
    <option style="color:gray" value="null">select one option</option>_x000D_
    <option value="1" class="others">one</option>_x000D_
    <option value="2" class="others">two</option>_x000D_
</select>

But as you can see, because your first item in options is the first thing that your select control shows, you can not see its assigned color. While if you open the select list and see the opened items, you will see you could assign a gray color to the first option. So you need something else in jQuery.

$(document).ready(function() {
   $('#select').css('color','gray');
   $('#select').change(function() {
      var current = $('#select').val();
      if (current != 'null') {
          $('#select').css('color','black');
      } else {
          $('#select').css('color','gray');
      }
   }); 
});

This is my code in jsFiddle.

Please add: CFLAGS="-lrt" and LDFLAGS="-lrt"

If you want to keep summing the digits until you get a single-digit number (one of my favorite characteristics of numbers divisible by 9) you can do:

def digital_root(n):
    x = sum(int(digit) for digit in str(n))
    if x < 10:
        return x
    else:
        return digital_root(x)

Which actually turns out to be pretty fast itself...

%timeit digital_root(12312658419614961365)

10000 loops, best of 3: 22.6 µs per loop

Why not in one line?

$('.offer').click(function(){
    $(this).find(':checkbox').attr('checked', !$(this).find(':checkbox').attr('checked'));
});

You can use the filter function to apply more complicated regex matching.

Here's an example which would just match the first three divs:

$('div')_x000D_
  .filter(function() {_x000D_
    return this.id.match(/abc+d/);_x000D_
  })_x000D_
  .html("Matched!");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>

You should call srand() before calling rand to initialize the random number generator.

Either call it with a specific seed, and you will always get the same pseudo-random sequence

#include <stdlib.h>

int main ()
{
  srand ( 123 );
  int random_number = rand();
  return 0;
}

or call it with a changing sources, ie the time function

#include <stdlib.h>
#include <time.h>

int main ()
{
  srand ( time(NULL) );
  int random_number = rand();
  return 0;
}

In response to Moon's Comment rand() generates a random number with an equal probability between 0 and RAND_MAX (a macro pre-defined in stdlib.h)

You can then map this value to a smaller range, e.g.

int random_value = rand(); //between 0 and RAND_MAX

//you can mod the result
int N = 33;
int rand_capped = random_value % N;  //between 0 and 32
int S = 50;
int rand_range = rand_capped + S; //between 50 and 82

//you can convert it to a float
float unit_random = random_value / (float) RAND_MAX; //between 0 and 1 (floating point)

This might be sufficient for most uses, but its worth pointing out that in the first case using the mod operator introduces a slight bias if N does not divide evenly into RAND_MAX+1.

Random number generators are interesting and complex, it is widely said that the rand() generator in the C standard library is not a great quality random number generator, read (http://en.wikipedia.org/wiki/Random_number_generation for a definition of quality).

http://en.wikipedia.org/wiki/Mersenne_twister (source http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html ) is a popular high quality random number generator.

Also, I am not aware of arc4rand() or random() so I cannot comment.

This worked for me

setInterval(ajax_query, 10000);

function ajax_query(){
   //Call ajax here
}

Credit must be given to IronRazerz in a response to TextBox watermark (CueBanner) which goes away when user types in single line TextBox (not for RichTextBox).

You will need to declare the following in your class:

private const int CB_SETCUEBANNER = 0x1703;

[System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
private static extern int SendMessage(IntPtr hWnd, int msg, int wParam, [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.LPWStr)]string lParam);

Then you can use it with something like:

SendMessage(this.comboBox1.Handle, CB_SETCUEBANNER, 0, "Please select an item...");

This is assuming the Combo Box's DropDownStyle is set to DropDownList, as is the original poster's question.

This should result in something like the following:

body{
  margin:0;
  background:url('image.png') no-repeat 50% 50% fixed;
  background-size: cover;
}

The m_ prefix is often used for member variables - I think its main advantage is that it helps create a clear distinction between a public property and the private member variable backing it:

int m_something

public int Something => this.m_something; 

It can help to have a consistent naming convention for backing variables, and the m_ prefix is one way of doing that - one that works in case-insensitive languages.

How useful this is depends on the languages and the tools that you're using. Modern IDEs with strong refactor tools and intellisense have less need for conventions like this, and it's certainly not the only way of doing this, but it's worth being aware of the practice in any case.

df <- data.frame(a = 1:2, b = letters[1:2]) 
df[rep(seq_len(nrow(df)), each = 2), ]

function distRandom(){
  do{
    x=random(DISTRIBUTION_DOMAIN);
  }while(random(DISTRIBUTION_RANGE)>=distributionFunction(x));
  return x;
}

%...% operators

%>% has no builtin meaning but the user (or a package) is free to define operators of the form %whatever% in any way they like. For example, this function will return a string consisting of its left argument followed by a comma and space and then it's right argument.

"%,%" <- function(x, y) paste0(x, ", ", y)

# test run

"Hello" %,% "World"
## [1] "Hello, World"

The base of R provides %*% (matrix mulitiplication), %/% (integer division), %in% (is lhs a component of the rhs?), %o% (outer product) and %x% (kronecker product). It is not clear whether %% falls in this category or not but it represents modulo.

expm The R package, expm, defines a matrix power operator %^%. For an example see Matrix power in R .

operators The operators R package has defined a large number of such operators such as %!in% (for not %in%). See http://cran.r-project.org/web/packages/operators/operators.pdf

igraph This package defines %--% , %->% and %<-% to select edges.

lubridate This package defines %m+% and %m-% to add and subtract months and %--% to define an interval. igraph also defines %--% .

Pipes

magrittr In the case of %>% the magrittr R package has defined it as discussed in the magrittr vignette. See http://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html

magittr has also defined a number of other such operators too. See the Additional Pipe Operators section of the prior link which discusses %T>%, %<>% and %$% and http://cran.r-project.org/web/packages/magrittr/magrittr.pdf for even more details.

dplyr The dplyr R package used to define a %.% operator which is similar; however, it has been deprecated and dplyr now recommends that users use %>% which dplyr imports from magrittr and makes available to the dplyr user. As David Arenburg has mentioned in the comments this SO question discusses the differences between it and magrittr's %>% : Differences between %.% (dplyr) and %>% (magrittr)

pipeR The R package, pipeR, defines a %>>% operator that is similar to magrittr's %>% and can be used as an alternative to it. See http://renkun.me/pipeR-tutorial/

The pipeR package also has defined a number of other such operators too. See: http://cran.r-project.org/web/packages/pipeR/pipeR.pdf

postlogic The postlogic package defined %if% and %unless% operators.

wrapr The R package, wrapr, defines a dot pipe %.>% that is an explicit version of %>% in that it does not do implicit insertion of arguments but only substitutes explicit uses of dot on the right hand side. This can be considered as another alternative to %>%. See https://winvector.github.io/wrapr/articles/dot_pipe.html

Bizarro pipe. This is not really a pipe but rather some clever base syntax to work in a way similar to pipes without actually using pipes. It is discussed in http://www.win-vector.com/blog/2017/01/using-the-bizarro-pipe-to-debug-magrittr-pipelines-in-r/ The idea is that instead of writing:

1:8 %>% sum %>% sqrt
## [1] 6

one writes the following. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.) . We follow that with a semicolon.

1:8 ->.; sum(.) ->.; sqrt(.)
## [1] 6

Update Added info on expm package and simplified example at top. Added postlogic package.

All these keywords try, catch and throw are related to the exception handling concept in java. An exception is an event that occurs during the execution of programs. Exception disrupts the normal flow of an application. Exception handling is a mechanism used to handle the exception so that the normal flow of application can be maintained. Try-catch block is used to handle the exception. In a try block, we write the code which may throw an exception and in catch block we write code to handle that exception. Throw keyword is used to explicitly throw an exception. Generally, throw keyword is used to throw user defined exceptions.

If you are using SQL Server try Linked Server

Refering to Andrie's answer, suggesting to use plyr::rbind.fill(): Combined with t() you have something like cbind.fill() (which is not part of plyr) that will construct your data frame with consideration of identical case numbers.

The documentation for writelines() states:

writelines() does not add line separators

So you'll need to add them yourself. For example:

    line_list.append(new_line + "\n")

whenever you append a new item to line_list.

With gawk , you can use match function:

    x="hey there how are you"
    echo "$x" |awk --re-interval '{match($0,/(.{4})how(.{4})/,a);print a[1],a[2]}'
    ere   are

If you are ok with perl, more flexible solution : Following will print three characters before the pattern followed by actual pattern and then 5 character after the pattern.

echo hey there how are you |perl -lne 'print "$1$2$3" if /(.{3})(there)(.{5})/'
ey there how

This can also be applied to words instead of just characters.Following will print one word before the actual matching string.

echo hey there how are you |perl -lne 'print $1 if /(\w+) there/'
hey

Following will print one word after the pattern:

echo hey there how are you |perl -lne 'print $2 if /(\w+) there (\w+)/'
how

Following will print one word before the pattern , then the actual word and then one word after the pattern:

echo hey there how are you |perl -lne 'print "$1$2$3" if /(\w+)( there )(\w+)/'
hey there how

<View style={{flexDirection:'row'}}> 
   <Text style={{ flex: number }}> You miss fdddddd dddddddd 
     You miss fdd
   </Text>
</View>

{ flex: aNumber } is all you need!

Just set 'flex' to a number that suit for you. And then the text will wrap.

Here is a sample using pysftp and a private key.

import pysftp

def upload_file(file_path):

    private_key = "~/.ssh/your-key.pem"  # can use password keyword in Connection instead
    srv = pysftp.Connection(host="your-host", username="user-name", private_key=private_key)
    srv.chdir('/var/web/public_files/media/uploads')  # change directory on remote server
    srv.put(file_path)  # To download a file, replace put with get
    srv.close()  # Close connection

pysftp is an easy to use sftp module that utilizes paramiko and pycrypto. It provides a simple interface to sftp.. Other things that you can do with pysftp which are quite useful:

data = srv.listdir()  # Get the directory and file listing in a list
srv.get(file_path)  # Download a file from remote server
srv.execute('pwd') # Execute a command on the server

More commands and about PySFTP here.

When you don’t define any constructor in your class, compiler defines default one for you, however when you declare any constructor (in your example you have already defined a parameterized constructor), compiler doesn’t do it for you.

Since you have defined a constructor in class code, compiler didn’t create default one. While creating object you are invoking default one, which doesn’t exist in class code. Then the code gives an compilation error.

In my case, I named an Entity of my Core Data Model the same as an Object. So: I defined an object "Event.h" and at the same time I had this entity called "Event". I ended up renaming the entity.

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

The java 8 way:

StringJoiner sj1 = new StringJoiner(", ");
String joined = sj1.add("one").add("two").toString();
// one, two
System.out.println(joined);


StringJoiner sj2 = new StringJoiner(", ","{", "}");
String joined2 = sj2.add("Jake").add("John").add("Carl").toString();
// {Jake, John, Carl}
System.out.println(joined2);

Topics are for the publisher-subscriber model, while queues are for point-to-point.

Use lastIndexOf. Like:

string var = var.lastIndexOf(',');

Now has a new nuget package, try use it: https://www.nuget.org/packages/Oracle.ManagedDataAccess.EntityFramework/

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

1. git reset --soft <commit>

2. git checkout <branch>

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

From git docs:

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

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

Adam has already suggested database profiles.

You could check the SQLNET.ORA file. There's an EXPIRE_TIME parameter but this is for detecting lost connections, rather than terminating existing ones.

Given it happens overnight, it sounds more like an idle timeout, which could be down to a firewall between the app server and database server. Setting the EXPIRE_TIME may stop that happening (as there'll be check every 10 minutes to check the client is alive).

Or possibly the database is being shutdown and restarted and that is killing the connections.

Alternatively, you should be able to configure tomcat with a validationQuery so that it will automatically restart the connection without a tomcat restart

EOF is just a macro with a value (usually -1). You have to test something against EOF, such as the result of a getchar() call.

One way to test for the end of a stream is with the feof function.

if (feof(stdin))

Note, that the 'end of stream' state will only be set after a failed read.

In your example you should probably check the return value of scanf and if this indicates that no fields were read, then check for end-of-file.

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

Are you sure you want to filter the Collection itself, rather than an iterator?

see org.apache.commons.collections.iterators.FilterIterator

or using version 4 of apache commons org.apache.commons.collections4.iterators.FilterIterator

text-align: center will center it horizontally as for vertically put it in a span and give it a css of margin:auto 0; (you will probably also have to give the span a display: block property)

nchar requires more space than nvarchar.

eg,

A nchar(100) will always store 100 characters even if you only enter 5, the remaining 95 chars will be padded with spaces. Storing 5 characters in a nvarchar(100) will save 5 characters.

Mocking final/static classes/methods is possible with Mockito v2 only.

add this in your gradle file:

testImplementation 'org.mockito:mockito-inline:2.13.0'

This is not possible with Mockito v1, from the Mockito FAQ:

What are the limitations of Mockito

• Needs java 1.5+

• Cannot mock final classes

...

I came up with a solution that even I can understand... by using the 'Contains' method you can chain as many WHERE's as you like. If the WHERE is an empty string, it's ignored (or evaluated as a select all). Here is my example of joining 2 tables in LINQ, applying multiple where clauses and populating a model class to be returned to the view. (this is a select all).

public ActionResult Index()
    {
        string AssetGroupCode = "";
        string StatusCode = "";
        string SearchString = "";

        var mdl = from a in _db.Assets
                  join t in _db.Tags on a.ASSETID equals t.ASSETID
                  where a.ASSETGROUPCODE.Contains(AssetGroupCode)
                  && a.STATUSCODE.Contains(StatusCode)
                  && (
                  a.PO.Contains(SearchString)
                  || a.MODEL.Contains(SearchString)
                  || a.USERNAME.Contains(SearchString)
                  || a.LOCATION.Contains(SearchString)
                  || t.TAGNUMBER.Contains(SearchString)
                  || t.SERIALNUMBER.Contains(SearchString)
                  )
                  select new AssetListView
                  {
                      AssetId = a.ASSETID,
                      TagId = t.TAGID,
                      PO = a.PO,
                      Model = a.MODEL,
                      UserName = a.USERNAME,
                      Location = a.LOCATION,
                      Tag = t.TAGNUMBER,
                      SerialNum = t.SERIALNUMBER
                  };


        return View(mdl);
    }

res.json forces the argument to JSON. res.send will take an non-json object or non-json array and send another type. For example:

This will return a JSON number.

res.json(100)

This will return a status code and issue a warning to use sendStatus.

res.send(100)

If your argument is not a JSON object or array (null,undefined,boolean,string), and you want to ensure it is sent as JSON, use res.json.

I use following extension methods for epoch conversion

public static int GetEpochSeconds(this DateTime date)
    {
        TimeSpan t = DateTime.UtcNow - new DateTime(1970, 1, 1);
        return (int)t.TotalSeconds;
    }

public static DateTime FromEpochSeconds(this DateTime date, long EpochSeconds)
    {
        var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
        return epoch.AddSeconds(EpochSeconds);

    }

It can also be done using backtracking by maintaining a visited array.

void foo(vector<vector<int> > &s,vector<int> &data,int go,int k,vector<int> &vis,int tot)
{

    vis[go]=1;
    data.push_back(go);
    if(data.size()==k)
    {
        s.push_back(data);
        vis[go]=0;
    data.pop_back();
        return;
    }

    for(int i=go+1;i<=tot;++i)
    {
       if(!vis[i])
       {
           foo(s,data,i,k,vis,tot);
       }
    }
    vis[go]=0;
    data.pop_back();
}


vector<vector<int> > Solution::combine(int n, int k) {
   vector<int> data;
   vector<int> vis(n+1,0);
   vector<vector<int> > sol;
   for(int i=1;i<=n;++i)
   {
       for(int i=1;i<=n;++i) vis[i]=0;
   foo(sol,data,i,k,vis,n);
   }
   return sol;

}

Walltearer's solution is excellent, particularly if enclosed in a 'pre' tag:

<pre>
<?php debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS); ?>
</pre>

- which sets out the calls on separate lines, neatly numbered

Let's say you have a path with a file in this format:

/dirA/dirB/dirC/filename.file

Now you only want the path which includes four "/". Type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-4 -d"/"

and your output will be

/dirA/dirB/dirC

The advantage of using cut is that you can also cut out the uppest directory as well as the file (in this example), so if you type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-3 -d"/"

your output would be

/dirA/dirB

Though you can do the same from the other side of the string, it would not make that much sense in this case as typing

$ echo "/dirA/dirB/dirC/filename.file" | cut -f2-4 -d"/"

results in

dirA/dirB/dirC

In some other cases the last case might also be helpful. Mind that there is no "/" at the beginning of the last output.

There is a simple way using Linq GroupBy Method.

var duplicateValues = dt.AsEnumerable() 

        .GroupBy(row => row[0]) 

        .Where(group => (group.Count() == 1 || group.Count() > 1)) 

        .Select(g => g.Key); 



foreach (var d in duplicateValues)

        Console.WriteLine(d);

Try this.. layout_shadow.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#CABBBBBB"/>
            <corners android:radius="2dp" />
        </shape>
    </item>

    <item
        android:left="0dp"
        android:right="0dp"
        android:top="0dp"
        android:bottom="2dp">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white"/>
            <corners android:radius="2dp" />
        </shape>
    </item>
</layer-list>

Apply to your layout like this

 android:background="@drawable/layout_shadow"

I would say everything probably works except that the column idx doesn't actually exist in the table you're selecting from. Maybe you meant to select from @Practitioner:

WHILE (@i <= (SELECT MAX(idx) FROM @Practitioner))

because that's defined in the code above like that:

DECLARE @Practitioner TABLE (
    idx smallint Primary Key IDENTITY(1,1)
    , PractitionerId int
)

You can use os.stat(path) call

http://docs.python.org/library/os.html#os.stat

Personally, I'd go for the function approach

def get_parent_dir(directory):
    import os
    return os.path.dirname(directory)

current_dirs_parent = get_parent_dir(os.getcwd())

Use the keys() iterator to iterate over all the properties, and call get() for each.

Iterator<String> iter = json.keys();
while (iter.hasNext()) {
    String key = iter.next();
    try {
        Object value = json.get(key);
    } catch (JSONException e) {
        // Something went wrong!
    }
}

This is a copy/pastable function to be used based on the previous responses.

  /**
     * @param context
     * @return the Screen height in DP
     */
    public static float getHeightDp(Context context) {
        DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
        float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
        return dpHeight;
    }

    /**
     * @param context
     * @return the screnn width in dp
     */
    public static float getWidthDp(Context context) {
        DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
        float dpWidth = displayMetrics.widthPixels / displayMetrics.density;
        return dpWidth;
    }

hasOwnProperty() is a nice property to validate object keys. Example:

var obj = {a:1, b:2};

obj.hasOwnProperty('a') // true

When I want to tidy up an array like this I use:

["Kathmandu", "Pokhara", "", "Dharan", "Butwal"] - ["", nil]

This will remove all blank or nil elements.

Populate the text box values in the Page Init event as opposed to using the Postback.

protected void Page_Init(object sender, EventArgs e)
{
    DropDownTitle();
}

From my experience, there is at least one clear advantage when using event.preventDefault() over using return false. Suppose you are capturing the click event on an anchor tag, otherwise which it would be a big problem if the user were to be navigated away from the current page. If your click handler uses return false to prevent browser navigation, it opens the possibility that the interpreter will not reach the return statement and the browser will proceed to execute the anchor tag's default behavior.

$('a').click(function (e) {
  // custom handling here

  // oops...runtime error...where oh where will the href take me?

  return false;
});

The benefit to using event.preventDefault() is that you can add this as the first line in the handler, thereby guaranteeing that the anchor's default behavior will not fire, regardless if the last line of the function is not reached (eg. runtime error).

$('a').click(function (e) {
  e.preventDefault();

  // custom handling here

  // oops...runtime error, but at least the user isn't navigated away.
});

I think this is the best approach. Using generic ArrayAdapter class and extends your own Object adapter is as simple as follows:

public abstract class GenericArrayAdapter<T> extends ArrayAdapter<T> {

  // Vars
  private LayoutInflater mInflater;

  public GenericArrayAdapter(Context context, ArrayList<T> objects) {
    super(context, 0, objects);
    init(context);
  }

  // Headers
  public abstract void drawText(TextView textView, T object);

  private void init(Context context) {
    this.mInflater = LayoutInflater.from(context);
  }

  @Override public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder vh;
    if (convertView == null) {
      convertView = mInflater.inflate(android.R.layout.simple_list_item_1, parent, false);
      vh = new ViewHolder(convertView);
      convertView.setTag(vh);
    } else {
      vh = (ViewHolder) convertView.getTag();
    }

    drawText(vh.textView, getItem(position));

    return convertView;
  }

  static class ViewHolder {

    TextView textView;

    private ViewHolder(View rootView) {
      textView = (TextView) rootView.findViewById(android.R.id.text1);
    }
  }
}

and here your adapter (example):

public class SizeArrayAdapter extends GenericArrayAdapter<Size> {

  public SizeArrayAdapter(Context context, ArrayList<Size> objects) {
    super(context, objects);
  }

  @Override public void drawText(TextView textView, Size object) {
    textView.setText(object.getName());
  }

}

and finally, how to initialize it:

ArrayList<Size> sizes = getArguments().getParcelableArrayList(Constants.ARG_PRODUCT_SIZES);
SizeArrayAdapter sizeArrayAdapter = new SizeArrayAdapter(getActivity(), sizes);
listView.setAdapter(sizeArrayAdapter);

I've created a Gist with TextView layout gravity customizable ArrayAdapter:

https://gist.github.com/m3n0R/8822803

You cannot have two TIMESTAMP column with the same default value of CURRENT_TIMESTAMP on your table. Please refer to this link: http://www.mysqltutorial.org/mysql-timestamp.aspx

You should check the download attribute and the window.URL method because the download attribute doesn't seem to like data URI. This example by Google is pretty much what you are trying to do.

You could do this two different ways. One is by using "as"

has_many :tasks, :as => :jobs

or

def jobs
     self.tasks
end

Obviously the first one would be the best way to handle it.

The APK file is in the /workspace/PROJECT_FOLDER/bin directory. To install the APK file in a real device:

1. Connect your real device with a PC/laptop.

2. Go to sdk/tools/ using a terminal or command prompt.

3. adb install <FILE PATH OF .APK FILE>

That's it...

The easiest way is to use lubridate:

library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)

This function automatically returns objects of class POSIXct and will work with either factors or characters.

I use Composer-Setup.exe and it works fine. Just in case you need to know where is the composer.phar (to use with PhpStorm) :

C:\ProgramData\ComposerSetup\bin\composer.phar

List<Integer> figureTypes = new ArrayList<Integer>(
                           Arrays.asList(
                                 1,
                                 2
                            ));

List<Integer> figureTypes2 = new ArrayList<Integer>(
                           Arrays.asList(
                                 1,
                                 2));

assertTrue(figureTypes .equals(figureTypes2 ));

If all your values are unique, you can make a reverse dictionary:

PIXO_reverse = {v: k for k, v in PIX0.items()}

Result:

>>> PIXO_reverse

{'320x240': 'QVGA', '640x480': 'VGA', '800x600': 'SVGA'}

Now you can use the same logic as before.

It sounds like you have installed SQL Server 2005 Express Edition, which does not include SSIS or the Business Intelligence Development Studio.

BIDS is only provided with the (not free) Standard, Enterprise and Developer Editions.

EDIT

This information was correct for SQL Server 2005. Since SQL Server 2014, Developer Edition has been free. BIDS has been replaced by SQL Server Data Tools, a free plugin for Visual Studio (including the free Visual Studio Community Edition).

Observable values can be retrieved from any locations. The source sequence is first pushed onto a special observer that is able to emit elsewhere. This is achieved with the Subject class from the Reactive Extensions (RxJS).

var subject = new Rx.AsyncSubject();  // store-last-value method

Store value onto the observer.

subject.next(value); // store value
subject.complete(); // publish only when sequence is completed

To retrieve the value from elsewhere, subscribe to the observer like so:

subject.subscribe({
  next: (response) => {
      //do stuff. The property name "response" references the value
  }
});

Subjects are both Observables and Observers. There are other Subject types such as BehaviourSubject and ReplaySubject for other usage scenarios.

Don't forget to import RxJS.

var Rx = require('rxjs');

in your shell script (or .bashrc) you may use somthing like:

umask 022

umask is a command that determines the settings of a mask that controls how file permissions are set for newly created files.

auto is not a valid value for padding property, the only thing you can do is take out padding: 0; from the * declaration, else simply assign padding to respective property block.

If you remove padding: 0; from * {} than browser will apply default styles to your elements which will give you unexpected cross browser positioning offsets by few pixels, so it is better to assign padding: 0; using * and than if you want to override the padding, simply use another rule like

.container p {
   padding: 5px;
}

I typically see a 30% speed improvement for compute-intensive code on x86-64 compared to x86. This is most likely due to the fact that we have 16 x 64 bit general purpose registers and 16 x SSE registers instead of 8 x 32 bit general purpose registers and 8 x SSE registers. This is with the Intel ICC compiler (11.1) on an x86-64 Linux - results with other compilers (e.g. gcc), or with other operating systems (e.g. Windows), may be different of course.

Did you set the CSS:

html, body
{
    height: 100%;
}

You need this to be able to make the div take up all the space. :)

A MemoryStream can be helpful for this. You could put it in an extension method:

public static class ImageExtensions
{
    public static byte[] ToByteArray(this Image image, ImageFormat format)
    {
        using(MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, format);
            return ms.ToArray();
        }
    }
}

You could just use it like:

var image = new Bitmap(10, 10);
// Draw your image
byte[] arr = image.ToByteArray(ImageFormat.Bmp);

I partially disagree with prestomanifto's answer in regards to the ImageConverter. Do not use ImageConverter. There's nothing technically wrong with it, but simply the fact that it uses boxing/unboxing from object tells me it's code from the old dark places of the .NET framework and its not ideal to use with image processing (it's overkill for converting to a byte[] at least), especially when you consider the following.

I took a look at the ImageConverter code used by the .Net framework, and internally it uses code almost identical to the one I provided above. It creates a new MemoryStream, saves the Bitmap in whatever format it was in when you provided it, and returns the array. Skip the extra overhead of creating an ImageConverter class by using MemoryStream

Have you tried?

var isoDateTimeFormat = CultureInfo.InvariantCulture.DateTimeFormat;

// "2013-10-10T22:10:00"
 dateValue.ToString(isoDateTimeFormat.SortableDateTimePattern); 

// "2013-10-10 22:10:00Z"    
dateValue.ToString(isoDateTimeFormat.UniversalSortableDateTimePattern)

Also try using parameters when you store the c# datetime value in the mySql database, this might help.

I got the error when I just changing some svn settings and not anything in the code. Just cleaning the projects fixed the error.

See https://bootstrap.themes.guide/how-to-customize-bootstrap.html

1. For simple CSS Overrides, you can add a custom.css below the bootstrap.css

   <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
   <link rel="stylesheet" type="text/css" href="css/custom.css">
   

2. For more extensive changes, SASS is the recommended method.

   • create your own custom.scss
   • import Bootstrap after the changes in custom.scss

   • For example, let’s change the body background-color to light-gray #eeeeee, and change the blue primary contextual color to Bootstrap's $purple variable...

     /* custom.scss */    
     
     /* import the necessary Bootstrap files */
     @import "bootstrap/functions";
     @import "bootstrap/variables";
     
     /* -------begin customization-------- */   
     
     /* simply assign the value */ 
     $body-bg: #eeeeee;
     
     /* or, use an existing variable */
     $theme-colors: (
       primary: $purple
     );
     /* -------end customization-------- */  
     
     /* finally, import Bootstrap to set the changes! */
     @import "bootstrap";
     

Using a single Awk:

... | awk -F '[/:]' '{print $5}'

That is, using as field separator either / or :, the username is always in field 5.

To store it in a variable:

username=$(... | awk -F '[/:]' '{print $5}')

A more flexible implementation with sed that doesn't require username to be field 5:

... | sed -e s/:.*// -e s?.*/??

That is, delete everything from : and beyond, and then delete everything up until the last /. sed is probably faster too than awk, so this alternative is definitely better.

In my case:

sudo -E add-apt-repository ppa:linuxuprising/java

sudo apt-get update

sudo apt install  oracle-java12-installer

that works fine

hit git init using terminal/cmd in your desired folder. It'll do the job.

Well you seem to have mistaken them both for what they do.

$(window).height() gets you an unit-less pixel value of the height of the (browser) window aka viewport. With respect to the web browsers the viewport here is visible portion of the canvas(which often is smaller than the document being rendered).

$(document).height() returns an unit-less pixel value of the height of the document being rendered. However, if the actual document’s body height is less than the viewport height then it will return the viewport height instead.

Hope that clears things a little.

• utf8 is MySQL's older, flawed implementation of UTF-8 which is in the process of being deprecated.
• utf8mb4 is what they named their fixed UTF-8 implementation, and is what you should use right now.

In their flawed version, only characters in the first 64k character plane - the basic multilingual plane - work, with other characters considered invalid. The code point values within that plane - 0 to 65535 (some of which are reserved for special reasons) can be represented by multi-byte encodings in UTF-8 of up to 3 bytes, and MySQL's early version of UTF-8 arbitrarily decided to set that as a limit. At no point was this limitation a correct interpretation of the UTF-8 rules, because at no point was UTF-8 defined as only allowing up to 3 bytes per character. In fact, the earliest definitions of UTF-8 defined it as having up to 6 bytes (since revised to 4). MySQL's original version was always arbitrarily crippled.

Back when MySQL released this, the consequences of this limitation weren't too bad as most Unicode characters were in that first plane. Since then, more and more newly defined character ranges have been added to Unicode with values outside that first plane. Unicode itself defines 17 planes, though so far only 7 of these are used.

In an effort not to break old code making any particular assumptions, MySQL retained the broken implementation and called the newer, fixed version utf8mb4. This has led to some confusion with the name being misinterpreted as if it's some kind of extension to UTF-8 or alternative form of UTF-8, rather than MySQL's implementation of the true UTF-8.

Future versions of MySQL will eventually phase out the older version, and for now it can be considered deprecated. For the foreseeable future you need to use utf8mb4 to ensure correct UTF-8 encoding. After sufficient time has passed, the current utf8 will be removed, and at some future date utf8 will rise again, this time referring to the fixed version, though utf8mb4 will continue to unambiguously refer to the fixed version.

Thought this would be helpful for others with the same issue, as I've seen a few on here - I ran into this, but found I loaded slick.js AFTER my main.js (which was calling the slick() function). swapped the two and it works great

I had this exact same problem with Xampp portable on Windows 10 Home. I went through all the suggestions and none worked. I did get it working with Windows Firewall Settings and an error on my part.

My pen drive was labelled Drive E on my laptop and Drive F on my Desktop. Once I corrected that using disk partition and changed the drive letter to E for my desktop to windows asked for access for the firewall and everything clicked.

The steps to correct the drive letter were: 1. Hit the windows key and type Partition, "create and format harddisks partitions" should be at the top, hit enter 2. Find the drive you are looking for at the top panel and click on it. 3. Right click on it and select change drive letter and path, click okay 4. Now try to start xampp control panel and start Apache and Mysql 5. if you get the windows firewall click allow.

I can't say this will work but it did for me and is what I added to this discussion. I also think it might have been just the firewall did not allow the oither drive letter.

One of the aspects of .NET I like the most are generics. Even if you write procedural code in F#, you will still benefit from type inference. It makes writing generic code easy.

In C#, you write concrete code by default, and you have to put in some extra work to write generic code.

In F#, you write generic code by default. After spending over a year of programming in both F# and C#, I find that library code I write in F# is both more concise and more generic than the code I write in C#, and is therefore also more reusable. I miss many opportunities to write generic code in C#, probably because I'm blinded by the mandatory type annotations.

There are however situations where using C# is preferable, depending on one's taste and programming style.

• C# does not impose an order of declaration among types, and it's not sensitive to the order in which files are compiled.
• C# has some implicit conversions that F# cannot afford because of type inference.

Here is class structure of UIDevice

+ (UIDevice *)currentDevice;

@property(nonatomic,readonly,strong) NSString    *name;              // e.g. "My iPhone"
@property(nonatomic,readonly,strong) NSString    *model;             // e.g. @"iPhone", @"iPod touch"
@property(nonatomic,readonly,strong) NSString    *localizedModel;    // localized version of model
@property(nonatomic,readonly,strong) NSString    *systemName;        // e.g. @"iOS"
@property(nonatomic,readonly,strong) NSString    *systemVersion;

I would rather use Last() from LINQ to do it.

rows = rows.Remove(rows.Last());

or

rows = rows.Remove(rows.LastOrDefault());

The way I fix this problem is:

1. create a link from adb file(drag 'adb' with holding alt then drop to any directory and select 'link here')
2. use #sudo cp adb /bin (copy link from 1 to /bin)

I've done this several times and it works 100%(tested on Ubuntu 12.04 32/64bit).

Forms in C# are classes that inherit the Form base class.

You can show a popup by creating an instance of the class and calling ShowDialog().

I tried deleting .git/indexbut didn't work, I end up uninstalling go and removing all folders that has go name in it, and then installing go again, and it workerd!

You don`t have to setup variable, you can just set if it is moving in data-attribute

$youtubeSlider.find('a')
    .on('mousedown', function (e) {
        $(this).data('moving', false);
    })
    .on('mousemove', function (e) {
        $(this).data('moving', true);
    })
    .on('mouseup', function (e) {
        if (!$(this).data('moving')) {
            // Open link
        }
    });

$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);

Note: only work for your example.

int converts by truncation, as has been mentioned by others. This can result in the answer being one different than expected. One way around this is to check if the result is 'close enough' to an integer and adjust accordingly, otherwise the usual conversion. This is assuming you don't get too much roundoff and calculation error, which is a separate issue. For example:

def toint(f):
    trunc = int(f)
    diff = f - trunc

    # trunc is one too low
    if abs(f - trunc - 1) < 0.00001:
        return trunc + 1
    # trunc is one too high
    if abs(f - trunc + 1) < 0.00001:
        return trunc - 1
    # trunc is the right value
    return trunc

This function will adjust for off-by-one errors for near integers. The mpmath library does something similar for floating point numbers that are close to integers.

I think your statement should look like:

SELECT id, 
   client,
   project,
   task,
   description, 
   time,
   date  
  INTO OUTFILE '/path/to/file.csv'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM ts

Mainly without the FIELDS ESCAPED BY '""' option, OPTIONALLY ENCLOSED BY '"' will do the trick for description fields etc and your numbers will be treated as numbers in Excel (not strings comprising of numerics)

Also try calling:

SET NAMES utf8;

before your outfile select, that might help getting the character encodings inline (all UTF8)

Let us know how you get on.

Swiftmailer is another easy-to-use script that automatically protects against email injection and makes attachments a breeze. I also strongly discourage using PHP's built-in mail() function.

To use:

• Download Swiftmailer, and place the lib folder in your project
• Include the main file using require_once 'lib/swift_required.php';

Now add the code when you need to mail:

// Create the message
$message = Swift_Message::newInstance()
    ->setSubject('Your subject')
    ->setFrom(array('[email protected]' => 'Web Master'))
    ->setTo(array('[email protected]'))
    ->setBody('Here is the message itself')
    ->attach(Swift_Attachment::fromPath('myPDF.pdf'));

//send the message          
$mailer->send($message);

More information and options can be found in the Swiftmailer Docs.

Try this:

sudo apt-get install -y curl

I was working on an app that was upgraded to iOS 8 and location services stopped working. You'll probably get and error in the Debug area like so:

Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.

I did the least intrusive procedure. First add NSLocationAlwaysUsageDescription entry to your info.plist:

Notice I didn't fill out the value for this key. This still works, and I'm not concerned because this is a in house app. Also, there is already a title asking to use location services, so I didn't want to do anything redundant.

Next I created a conditional for iOS 8:

if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [_locationManager requestAlwaysAuthorization];
}

After this the locationManager:didChangeAuthorizationStatus: method is call:

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:  (CLAuthorizationStatus)status
{
    [self gotoCurrenLocation];
}

And now everything works fine. As always, check out the documentation.

If you need a Swift Implementation of this follow the directions on the accepted answer and then in you UITableViewController implement the following methods:

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    return tableView.dequeueReusableCell(withIdentifier: "CustomHeader")
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 75
}

**Add elements in Final arraylist,**
**This will Help you sure**

import java.util.ArrayList;
import java.util.List;

public class NonDuplicateList {

public static void main(String[] args) {

    List<String> l1 = new ArrayList<String>();
    l1.add("1");l1.add("2");l1.add("3");l1.add("4");l1.add("5");l1.add("6");
    List<String> l2 = new ArrayList<String>();
    l2.add("1");l2.add("7");l2.add("8");l2.add("9");l2.add("10");l2.add("3");
    List<String> l3 = new ArrayList<String>();
    l3.addAll(l1);
    l3.addAll(l2);
    for (int i = 0; i < l3.size(); i++) {
        for (int j=i+1; j < l3.size(); j++) {
             if(l3.get(i) == l3.get(j)) {
                 l3.remove(j);
            }
        }
    }
    System.out.println(l3);
}

}

Output : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

If you want to avoid new dependencies you could make your own smart objects. Of course only if you want to do more that just get it's size.

MyNeatObj = function (obj) {
  var length = null;

  this.size = function () {
    if (length === null) {
      length = 0;
      for (var key in obj) length++;
    }
    return length;
  }
}

var thingy = new MyNeatObj(originalObj);
thingy.size();

Go to File > Project Structure > Select Module > Properties you will landing to this screen

Select Build Tools Version same as version selected in Compile Sdk Version.

Hope this will resolve your issue.

Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.

Gantt chart for this ques will be:

| P3 | P2 | P4 | P5 | P1 |

1    4    5    7   11   14

Average waiting time=(0+2+2+3+3)/5=2

Average Turnaround time=(3+3+4+7+6)/5=4.6

I know that this is an old question, but the ignore-unresolvable property was not working for me and I didn't know why.

The problem was that I needed an external resource (something like location="file:${CATALINA_HOME}/conf/db-override.properties") and the ignore-unresolvable="true" does not do the job in this case.

What one needs to do for ignoring a missing external resource is:

ignore-resource-not-found="true"

Just in case anyone else bumps into this.

Enable Remote Access (Grant) Home / Tutorials / Mysql / Enable Remote Access (Grant) If you try to connect to your mysql server from remote machine, and run into error like below, this article is for you.

ERROR 1130 (HY000): Host ‘1.2.3.4’ is not allowed to connect to this MySQL server

Change mysql config

Start with editing mysql config file

vim /etc/mysql/my.cnf

Comment out following lines.

#bind-address           = 127.0.0.1
#skip-networking

If you do not find skip-networking line, add it and comment out it.

Restart mysql server.

~ /etc/init.d/mysql restart

Change GRANT privilege

You may be surprised to see even after above change you are not getting remote access or getting access but not able to all databases.

By default, mysql username and password you are using is allowed to access mysql-server locally. So need to update privilege.

Run a command like below to access from all machines. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

Run a command like below to give access from specific IP. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

You can replace 1.2.3.4 with your IP. You can run above command many times to GRANT access from multiple IPs.

You can also specify a separate USERNAME & PASSWORD for remote access.

You can check final outcome by:

SELECT * from information_schema.user_privileges where grantee like "'USERNAME'%";

Finally, you may also need to run:

mysql> FLUSH PRIVILEGES;

Test Connection

From terminal/command-line:

mysql -h HOST -u USERNAME -pPASSWORD

If you get a mysql shell, don’t forget to run show databases; to check if you have right privileges from remote machines.

Bonus-Tip: Revoke Access

If you accidentally grant access to a user, then better have revoking option handy.

Following will revoke all options for USERNAME from all machines:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'%';
Following will revoke all options for USERNAME from particular IP:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'1.2.3.4';
Its better to check information_schema.user_privileges table after running REVOKE command.

If you see USAGE privilege after running REVOKE command, its fine. It is as good as no privilege at all. I am not sure if it can be revoked.

merge is used to bring two (or more) branches together.

a little example:

# on branch A:
# create new branch B
$ git checkout -b B
# hack hack
$ git commit -am "commit on branch B"

# create new branch C from A
$ git checkout -b C A
# hack hack
$ git commit -am "commit on branch C"

# go back to branch A
$ git checkout A
# hack hack
$ git commit -am "commit on branch A"

so now there are three separate branches (namely A B and C) with different heads

to get the changes from B and C back to A, checkout A (already done in this example) and then use the merge command:

# create an octopus merge
$ git merge B C

your history will then look something like this:

…-o-o-x-------A
      |\     /|
      | B---/ |
       \     /
        C---/

if you want to merge across repository/computer borders, have a look at git pull command, e.g. from the pc with branch A (this example will create two new commits):

# pull branch B
$ git pull ssh://host/… B
# pull branch C
$ git pull ssh://host/… C

You might have already received a response but this might help others since I experienced the same issue recently and this is what I did:

1. Provided a path entry to powershell. For me the path was C:\Windows\System32\WindowsPowerShell\v1.0

2. Then I opened cmd prompt with administrative privileges and copied this

   @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

into the cmd prompt.

3. Next, choco install nodejs
4. Restart and everything worked fine. Try opening cmd without admin privileges and run npm -v Cheers.

One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:

import math
import numpy
import scipy
import sympy

print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False

Use a Linux Live cd/usb and boot an that to be able to directly connect to your wifi hardware or use linux as the main OS with direct access to the wifi card and then use windows as a guest os, I know that this maybe not the ideal way but it will work.

This is the solution for mobile safari:

Google Chrome Developer Tools has (a currently experimental) feature called CSS Overview which will allow you to find unused CSS rules.

To enable it follow these steps:

1. Open up DevTools (Command+Option+I on Mac; Control+Shift+I on Windows)
2. Head over to DevTool Settings (Function+F1 on Mac; F1 on Windows)
3. Click open the Experiments section
4. Enable the CSS Overview option

Given this file:

$ cat words.txt
line1 word1 word2
line2 word3 word4
line3 word5 word6

If you just want one word at a time (ignoring the meaning of spaces vs line breaks in the file):

with open('words.txt','r') as f:
    for line in f:
        for word in line.split():
           print(word)    

Prints:

line1
word1
word2
line2
...
word6 

Similarly, if you want to flatten the file into a single flat list of words in the file, you might do something like this:

with open('words.txt') as f:
    flat_list=[word for line in f for word in line.split()]

>>> flat_list
['line1', 'word1', 'word2', 'line2', 'word3', 'word4', 'line3', 'word5', 'word6']

Which can create the same output as the first example with print '\n'.join(flat_list)...

Or, if you want a nested list of the words in each line of the file (for example, to create a matrix of rows and columns from a file):

with open('words.txt') as f:
    matrix=[line.split() for line in f]

>>> matrix
[['line1', 'word1', 'word2'], ['line2', 'word3', 'word4'], ['line3', 'word5', 'word6']]

If you want a regex solution, which would allow you to filter wordN vs lineN type words in the example file:

import re
with open("words.txt") as f:
    for line in f:
        for word in re.findall(r'\bword\d+', line):
            # wordN by wordN with no lineN

Or, if you want that to be a line by line generator with a regex:

 with open("words.txt") as f:
     (word for line in f for word in re.findall(r'\w+', line))

You could also check my md5 implementation. It should be approx. the same as the other posted above. Unfortunately, the performance is limited by the inner loop which is impossible to optimize more.

Use Object.keys()... it's the way to go.

I just got this error again today as I updated my machine (with updates for PHP) running Ubuntu 14.04. The distribution config file /etc/php5/fpm/pool.d/www.conf is fine and doesn't require any changes currently.

I found the following errors:

dmesg | grep php

The strange thing was that I have 2 sites running that utilize PHP-FPM on this machine one was running fine and the other (a Tiny Tiny RSS installation) gave me a 502, where both have been running fine before.

I compared both configuration files and found that fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; was missing for the affected site.

Both configuration files now contain the following block and are running fine again:

I know it's been a little over two years... but I was looking for a way to do this, and wasn't overly happy with the solution posted (it works fine, but I wanted a little more information as the import happens). When combining all the SQL files in to one, you don't get any sort of progress updates.

So I kept digging for an answer and thought this might be a good place to post what I found for future people looking for the same answer. Here's a command line in Windows that will import multiple SQL files from a folder. You run this from the command line while in the directory where mysql.exe is located.

for /f %f in ('dir /b <dir>\<mask>') do mysql --user=<user> --password=<password> <dbname> < <dir>\%f

With some assumed values (as an example):

for /f %f in ('dir /b c:\sqlbackup\*.sql') do mysql --user=mylogin --password=mypass mydb < c:\sqlbackup\%f

If you had two sets of SQL backups in the folder, you could change the *.sql to something more specific (like mydb_*.sql).

All those settings are necessary to choose which tags you are interested in, but in order to display these tags in a list, you also need to select the right Eclipse perspective. I finally discovered that the "Markers" tab containing the "Task" list is only available under the "Java EE" perspective... Hope this helps! :-)

Update 2016-05-27

As of React v15, support for SVG in React is (close to?) 100% parity with current browser support for SVG (source). You just need to apply some syntax transformations to make it JSX compatible, like you already have to do for HTML (class ? className, style="color: purple" ? style={{color: 'purple'}}). For any namespaced (colon-separated) attribute, e.g. xlink:href, remove the : and capitalize the second part of the attribute, e.g. xlinkHref. Here’s an example of an svg with <defs>, <use>, and inline styles:

function SvgWithXlink (props) {
    return (
        <svg
            width="100%"
            height="100%"
            xmlns="http://www.w3.org/2000/svg"
            xmlnsXlink="http://www.w3.org/1999/xlink"
        >
            <style>
                { `.classA { fill:${props.fill} }` }
            </style>
            <defs>
                <g id="Port">
                    <circle style={{fill:'inherit'}} r="10"/>
                </g>
            </defs>

            <text y="15">black</text>
            <use x="70" y="10" xlinkHref="#Port" />
            <text y="35">{ props.fill }</text>
            <use x="70" y="30" xlinkHref="#Port" className="classA"/>
            <text y="55">blue</text>
            <use x="0" y="50" xlinkHref="#Port" style={{fill:'blue'}}/>
        </svg>
    );
}

Working codepen demo

For more details on specific support, check the docs’ list of supported SVG attributes. And here’s the (now closed) GitHub issue that tracked support for namespaced SVG attributes.

Previous answer

You can do a simple SVG embed without having to use dangerouslySetInnerHTML by just stripping the namespace attributes. For example, this works:

        render: function() {
            return (
                <svg viewBox="0 0 120 120">
                    <circle cx="60" cy="60" r="50"/>
                </svg>
            );
        }

At which point you can think about adding props like fill, or whatever else might be useful to configure.

Why not use parseFloat?

var someNumber = 123.456;
someNumber = parseFloat(someNumber.toFixed(2));
alert(typeof(someNumber));
//alerts number

It's the response code a SIP User Agent Server (UAS) will send to the client after the client sends a CANCEL request for the original unanswered INVITE request (yet to receive a final response).

Here is a nice CANCEL SIP Call Flow illustration.

you can use not(expression) function

or

expression != true()

Here's a short-and-sweet version using the "DO" statement:

DO $$ 
    BEGIN
        BEGIN
            ALTER TABLE <table_name> ADD COLUMN <column_name> <column_type>;
        EXCEPTION

        END;

You can't pass these as parameters, you'll need to do variable substitution in the string on the client side, but this is a self contained query that only emits a message if the column already exists, adds if it doesn't and will continue to fail on other errors (like an invalid data type).

I don't recommend doing ANY of these methods if these are random strings coming from external sources. No matter what method you use (client-side or server-side dynamic strings executed as queries), it would be a recipe for disaster as it opens you to SQL injection attacks.

I found a jfiddle that might help here: http://jsfiddle.net/jaredwilli/SfJ8c/

Ive refactored the code to make it simpler for this.

// In your controller
var w = angular.element($window);
$scope.$watch(
  function () {
    return $window.innerWidth;
  },
  function (value) {
    $scope.windowWidth = value;
  },
  true
);

w.bind('resize', function(){
  $scope.$apply();
});

You can then reference to windowWidth from the html

<span ng-bind="windowWidth"></span>

No, it's not possible, browsers have their own ways to implement tooltip. All you can do is to create some div that behaves like an HTML tooltip (mostly it's just 'show on hover') with Javascript, and then style it the way you want.

With this, you wouldn't have to worry about browser's zooming in or out, since the text inside the tooltip div is an actual HTML, it would scale accordingly.

You are making complex a very easy thing. You can add this in your CSS:

.capitalize {
    text-transform: capitalize;
}

In JavaScript, you can add the class to an element

 document.getElementById("element").className = "capitalize";

Content is what is passed as children. View is the template of the current component.

The view is initialized before the content and ngAfterViewInit() is therefore called before ngAfterContentInit().

** ngAfterViewInit() is called when the bindings of the children directives (or components) have been checked for the first time. Hence its perfect for accessing and manipulating DOM with Angular 2 components. As @Günter Zöchbauer mentioned before is correct @ViewChild() hence runs fine inside it.

Example:

@Component({
    selector: 'widget-three',
    template: `<input #input1 type="text">`
})
export class WidgetThree{
    @ViewChild('input1') input1;

    constructor(private renderer:Renderer){}

    ngAfterViewInit(){
        this.renderer.invokeElementMethod(
            this.input1.nativeElement,
            'focus',
            []
        )
    }
}

If you run your commands in a shell you can write something like "java -cp" and add any directories you want separated by ":" if java doesnt find something in one directory it will go try and find them in the other directories, that is what I do.

I just had this issue and solved it by editing mail.php under config folder. Usually when using shared hosting, they hosting company allows you to create an email such as

[email protected]

. So go to email settings under you shared hosting cpanel and add new email. Take that email and password and set it in the

mail.php.

It should work!

Unless your app is the default input method editor (IME) or is the app that currently has focus, your app cannot access clipboard data on Android 10 or higher. https://developer.android.com/about/versions/10/privacy/changes#clipboard-data

Sequences have a method index(value) which returns index of first occurrence - in your case this would be verts.index(value).

You can run it on verts[::-1] to find out the last index. Here, this would be len(verts) - 1 - verts[::-1].index(value)

Try to use .trim() first, before .equals(), or create a new String var that has these things.

I had a similar problem. My solution was to switch off the antivirus software (Avast), download the .iso file, mount it (double click in the Windows Explorer on the .iso file), and then run it from the PowerShell with admin rights with the following switches:

.\vs_community.exe /NoWeb /NoRefresh

This way you don't have to go offline or remove your existing installation.

Visual Studio Commmunity 2017 - dumpbin.exe became available once I installed the C++ profiling tools in Modify menu from the Visual Studio Installer.

This post is quite old. Most answers talk about Hibernate criteria, not JPA criteria. JPA 2.1 added CriteriaDelete/CriteriaUpdate, and EntityGraph that controls what exactly to fetch. Criteria API is better since Java is OO. That is why JPA is created. When JPQL is compiled, it will be translated to AST tree(OO model) before translated to SQL.

I'm very glad you asked! I was just working on explaining this very thing in our wikibook (which is obviously incomplete). We're working with Python novices, and had to help a few through exactly what you're asking!

Command-line Python in Windows:

1. Save your python code file somewhere, using "Save" or "Save as" in your editor. Lets call it 'first.py' in some folder, like "pyscripts" that you make on your Desktop.

2. Open a prompt (a Windows 'cmd' shell that is a text interface into the computer):

   start > run > "cmd" (in the little box). OK.

3. Navigate to where your python file is, using the commands 'cd' (change directory) and 'dir' (to show files in the directory, to verify your head). For our example something like,

   > cd C:\Documents and Settings\Gregg\Desktop\pyscripts

4. try:

   > python first.py

If you get this message:

'python' is not recognized as an internal or external command, operable program or batch file.

then python (the interpreter program that can translate Python into 'computer instructions') isn't on your path (see Putting Python in Your Path below). Then try calling it like this (assuming Python2.6, installed in the usual location):

> C:\Python26\python.exe first.py

(Advanced users: instead of first.py, you could write out first.py's full path of C:\Documents and Settings\Gregg\Desktop\pyscripts\first.py)

Putting Python In Your Path

Windows

In order to run programs, your operating system looks in various places, and tries to match the name of the program / command you typed with some programs along the way.

In windows:

control panel > system > advanced > |Environmental Variables| > system variables -> Path

this needs to include: C:\Python26; (or equivalent). If you put it at the front, it will be the first place looked. You can also add it at the end, which is possibly saner.

Then restart your prompt, and try typing 'python'. If it all worked, you should get a ">>>" prompt.

Do I really have to create an NSString for "Wrong"?

No, why not just do:

if([statusString isEqualToString:@"Wrong"]){
    //doSomething;
}

Using @"" simply creates a string literal, which is a valid NSString.

Also, can I compare the value of a UILabel.text to a string without assigning the label value to a string?

Yes, you can do something like:

UILabel *label = ...;
if([someString isEqualToString:label.text]) {
    // Do stuff here 
}

When you're running npm install in the project's root, it installs all of the npm dependencies into the project's node_modules directory.

If you take a look at the project's node_modules directory, you should see a directory called http-server, which holds the http-server package, and a .bin folder, which holds the executable binaries from the installed dependencies. The .bin directory should have the http-server binary (or a link to it).

So in your case, you should be able to start the http-server by running the following from your project's root directory (instead of npm start):

./node_modules/.bin/http-server -a localhost -p 8000 -c-1

This should have the same effect as running npm start.

If you're running a Bash shell, you can simplify this by adding the ./node_modules/.bin folder to your $PATH environment variable:

export PATH=./node_modules/.bin:$PATH

This will put this folder on your path, and you should be able to simply run

http-server -a localhost -p 8000 -c-1

This package uses recast in order to create an AST and then the parameter names are gathered from their, this allows it to support pattern matching, default arguments, arrow functions and other ES6 features.

How about importing the username and password from a file external to the script? That way even if someone got hold of the script, they wouldn't automatically get the password.

What's the default superuser username/password for postgres after a new install?:

CAUTION The answer about changing the UNIX password for "postgres" through "$ sudo passwd postgres" is not preferred, and can even be DANGEROUS!

This is why: By default, the UNIX account "postgres" is locked, which means it cannot be logged in using a password. If you use "sudo passwd postgres", the account is immediately unlocked. Worse, if you set the password to something weak, like "postgres", then you are exposed to a great security danger. For example, there are a number of bots out there trying the username/password combo "postgres/postgres" to log into your UNIX system.

What you should do is follow Chris James's answer:

sudo -u postgres psql postgres

# \password postgres

Enter new password: 

To explain it a little bit...

Shameless plug I know, but you might want to consider a jQuery plugin that I wrote:

https://github.com/benmajor/jQuery-Mobile-Events

It does not require jQuery Mobile, only jQuery.

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

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

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

or similar line in your shell configuration file.

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

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

python setup.py install --user

for Python 2.6+.

You can place each image side-by-side by writing the markdown for each image on the same line.

![alt-text-1](image1.png "title-1") ![alt-text-2](image2.png "title-2")

As long as the images aren't too large, they will display inline as demonstrated by this screen shot of a README file from GitHub:

Or you can use

<select [(ngModel)]="Answers[''+question.Name+'']" ng-options="option for option in question.Options">
        </select>

Quick Answer:

In a single line, the curl command would be:

a) If sending form data:

curl -X PUT -H "Content-Type: multipart/form-data;" -F "key1=val1" "YOUR_URI"

b) If sending raw data as json:

curl -X PUT -H "Content-Type: application/json" -d '{"key1":"value"}' "YOUR_URI"

c) If sending a file with a POST request:

curl -X POST "YOUR_URI" -F 'file=@/file-path.csv'

Alternative solution:

You can use the POSTMAN app from Chrome Store to get the equivalent cURL request. This is especially useful when writing more complicated requests.

For the request with other formats or for different clients like java, PHP, you can check out POSTMAN/comment below.

One possibility when ready stops working is that you have javascript code somewhere that is throwing an exception in a $(document).ready(...) or $(...) call, which is stopping processing of the rest of the ready blocks. Identify a single page on which this is occurring and examine it for possible errors in other places.

It is very simple. For example : in you JS controller use this:

$scope.inputngmodel.$valid = false;

or

$scope.inputngmodel.$invalid = true;

or

$scope.formname.inputngmodel.$valid = false;

or

$scope.formname.inputngmodel.$invalid = true;

All works for me for different requirement. Hit up if this solve your problem.

I've got the same error. I have been trying to fixing this by setting higher permission to account running SQL Client service, however it didnt help. The problem was that I run MS Sql Management studio just within my account. So, next time... assure that you are running it as Run as Administrator, if using Win7 with UAC enabled.

In xml:

<ImageView  
 android:clickable="true"  
 android:onClick="imageClick"  
 android:src="@drawable/myImage">  
 </ImageView>  

In code

 public class Test extends Activity {  
  ........  
  ........  
 public void imageClick(View view) {  
  //Implement image click function  
 }  

I did it with an ajax post and then returned using a data url:

$(document).ready(function () {
    var exportClick = function () {
        $.ajax({
           url: "/api/test.php",
           type: "POST",
           dataType: "text",
           data: {
              action: "getCSV",
              filter: "name = 'smith'",
           },
           success: function(data) {
              var w = window.open('data:text/csv;charset=utf-8,' + encodeURIComponent(data));
              w.focus();
           },
           error: function () {
              alert('Problem getting data');
           },
        });
    }
});

Example of using a function() in bash:

#!/bin/bash
# file.sh: a sample shell script to demonstrate the concept of Bash shell functions
# define usage function
usage(){
    echo "Usage: $0 filename"
    exit 1
}

# define is_file_exists function
# $f -> store argument passed to the script
is_file_exists(){
    local f="$1"
    [[ -f "$f" ]] && return 0 || return 1
}
# invoke  usage
# call usage() function if filename not supplied
[[ $# -eq 0 ]] && usage

# Invoke is_file_exits
if ( is_file_exists "$1" )
then
 echo "File found: $1"
else
 echo "File not found: $1"

Quick answer:
A child scope normally prototypically inherits from its parent scope, but not always. One exception to this rule is a directive with scope: { ... } -- this creates an "isolate" scope that does not prototypically inherit. This construct is often used when creating a "reusable component" directive.

As for the nuances, scope inheritance is normally straightfoward... until you need 2-way data binding (i.e., form elements, ng-model) in the child scope. Ng-repeat, ng-switch, and ng-include can trip you up if you try to bind to a primitive (e.g., number, string, boolean) in the parent scope from inside the child scope. It doesn't work the way most people expect it should work. The child scope gets its own property that hides/shadows the parent property of the same name. Your workarounds are

1. define objects in the parent for your model, then reference a property of that object in the child: parentObj.someProp
2. use $parent.parentScopeProperty (not always possible, but easier than 1. where possible)
3. define a function on the parent scope, and call it from the child (not always possible)

New AngularJS developers often do not realize that ng-repeat, ng-switch, ng-view, ng-include and ng-if all create new child scopes, so the problem often shows up when these directives are involved. (See this example for a quick illustration of the problem.)

This issue with primitives can be easily avoided by following the "best practice" of always have a '.' in your ng-models – watch 3 minutes worth. Misko demonstrates the primitive binding issue with ng-switch.

Having a '.' in your models will ensure that prototypal inheritance is in play. So, use

<input type="text" ng-model="someObj.prop1">

<!--rather than
<input type="text" ng-model="prop1">`
-->

JavaScript Prototypal Inheritance

Also placed on the AngularJS wiki: https://github.com/angular/angular.js/wiki/Understanding-Scopes

It is important to first have a solid understanding of prototypal inheritance, especially if you are coming from a server-side background and you are more familiar with class-ical inheritance. So let's review that first.

Suppose parentScope has properties aString, aNumber, anArray, anObject, and aFunction. If childScope prototypically inherits from parentScope, we have:

(Note that to save space, I show the anArray object as a single blue object with its three values, rather than an single blue object with three separate gray literals.)

If we try to access a property defined on the parentScope from the child scope, JavaScript will first look in the child scope, not find the property, then look in the inherited scope, and find the property. (If it didn't find the property in the parentScope, it would continue up the prototype chain... all the way up to the root scope). So, these are all true:

childScope.aString === 'parent string'
childScope.anArray[1] === 20
childScope.anObject.property1 === 'parent prop1'
childScope.aFunction() === 'parent output'

Suppose we then do this:

childScope.aString = 'child string'

The prototype chain is not consulted, and a new aString property is added to the childScope. This new property hides/shadows the parentScope property with the same name. This will become very important when we discuss ng-repeat and ng-include below.

Suppose we then do this:

childScope.anArray[1] = '22'
childScope.anObject.property1 = 'child prop1'

The prototype chain is consulted because the objects (anArray and anObject) are not found in the childScope. The objects are found in the parentScope, and the property values are updated on the original objects. No new properties are added to the childScope; no new objects are created. (Note that in JavaScript arrays and functions are also objects.)

Suppose we then do this:

childScope.anArray = [100, 555]
childScope.anObject = { name: 'Mark', country: 'USA' }

The prototype chain is not consulted, and child scope gets two new object properties that hide/shadow the parentScope object properties with the same names.

Takeaways:

• If we read childScope.propertyX, and childScope has propertyX, then the prototype chain is not consulted.
• If we set childScope.propertyX, the prototype chain is not consulted.

One last scenario:

delete childScope.anArray
childScope.anArray[1] === 22  // true

We deleted the childScope property first, then when we try to access the property again, the prototype chain is consulted.

Angular Scope Inheritance

The contenders:

• The following create new scopes, and inherit prototypically: ng-repeat, ng-include, ng-switch, ng-controller, directive with scope: true, directive with transclude: true.
• The following creates a new scope which does not inherit prototypically: directive with scope: { ... }. This creates an "isolate" scope instead.

Note, by default, directives do not create new scope -- i.e., the default is scope: false.

ng-include

Suppose we have in our controller:

$scope.myPrimitive = 50;
$scope.myObject    = {aNumber: 11};

And in our HTML:

<script type="text/ng-template" id="/tpl1.html">
<input ng-model="myPrimitive">
</script>
<div ng-include src="'/tpl1.html'"></div>

<script type="text/ng-template" id="/tpl2.html">
<input ng-model="myObject.aNumber">
</script>
<div ng-include src="'/tpl2.html'"></div>

Each ng-include generates a new child scope, which prototypically inherits from the parent scope.

Typing (say, "77") into the first input textbox causes the child scope to get a new myPrimitive scope property that hides/shadows the parent scope property of the same name. This is probably not what you want/expect.

Typing (say, "99") into the second input textbox does not result in a new child property. Because tpl2.html binds the model to an object property, prototypal inheritance kicks in when the ngModel looks for object myObject -- it finds it in the parent scope.

We can rewrite the first template to use $parent, if we don't want to change our model from a primitive to an object:

<input ng-model="$parent.myPrimitive">

Typing (say, "22") into this input textbox does not result in a new child property. The model is now bound to a property of the parent scope (because $parent is a child scope property that references the parent scope).

For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via scope properties $parent, $$childHead and $$childTail. I normally don't show these scope properties in the diagrams.

For scenarios where form elements are not involved, another solution is to define a function on the parent scope to modify the primitive. Then ensure the child always calls this function, which will be available to the child scope due to prototypal inheritance. E.g.,

// in the parent scope
$scope.setMyPrimitive = function(value) {
     $scope.myPrimitive = value;
}

Here is a sample fiddle that uses this "parent function" approach. (The fiddle was written as part of this answer: https://stackoverflow.com/a/14104318/215945.)

See also https://stackoverflow.com/a/13782671/215945 and https://github.com/angular/angular.js/issues/1267.

ng-switch

ng-switch scope inheritance works just like ng-include. So if you need 2-way data binding to a primitive in the parent scope, use $parent, or change the model to be an object and then bind to a property of that object. This will avoid child scope hiding/shadowing of parent scope properties.

See also AngularJS, bind scope of a switch-case?

ng-repeat

Ng-repeat works a little differently. Suppose we have in our controller:

$scope.myArrayOfPrimitives = [ 11, 22 ];
$scope.myArrayOfObjects    = [{num: 101}, {num: 202}]

And in our HTML:

<ul><li ng-repeat="num in myArrayOfPrimitives">
       <input ng-model="num">
    </li>
<ul>
<ul><li ng-repeat="obj in myArrayOfObjects">
       <input ng-model="obj.num">
    </li>
<ul>

For each item/iteration, ng-repeat creates a new scope, which prototypically inherits from the parent scope, but it also assigns the item's value to a new property on the new child scope. (The name of the new property is the loop variable's name.) Here's what the Angular source code for ng-repeat actually is:

childScope = scope.$new();  // child scope prototypically inherits from parent scope
...
childScope[valueIdent] = value;  // creates a new childScope property

If item is a primitive (as in myArrayOfPrimitives), essentially a copy of the value is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence child scope num) does not change the array the parent scope references. So in the first ng-repeat above, each child scope gets a num property that is independent of the myArrayOfPrimitives array:

This ng-repeat will not work (like you want/expect it to). Typing into the textboxes changes the values in the gray boxes, which are only visible in the child scopes. What we want is for the inputs to affect the myArrayOfPrimitives array, not a child scope primitive property. To accomplish this, we need to change the model to be an array of objects.

So, if item is an object, a reference to the original object (not a copy) is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence obj.num) does change the object the parent scope references. So in the second ng-repeat above, we have:

(I colored one line gray just so that it is clear where it is going.)

This works as expected. Typing into the textboxes changes the values in the gray boxes, which are visible to both the child and parent scopes.

ng-controller

Nesting controllers using ng-controller results in normal prototypal inheritance, just like ng-include and ng-switch, so the same techniques apply. However, "it is considered bad form for two controllers to share information via $scope inheritance" -- http://onehungrymind.com/angularjs-sticky-notes-pt-1-architecture/ A service should be used to share data between controllers instead.

(If you really want to share data via controllers scope inheritance, there is nothing you need to do. The child scope will have access to all of the parent scope properties. See also Controller load order differs when loading or navigating)

directives

1. default (scope: false) - the directive does not create a new scope, so there is no inheritance here. This is easy, but also dangerous because, e.g., a directive might think it is creating a new property on the scope, when in fact it is clobbering an existing property. This is not a good choice for writing directives that are intended as reusable components.
2. scope: true - the directive creates a new child scope that prototypically inherits from the parent scope. If more than one directive (on the same DOM element) requests a new scope, only one new child scope is created. Since we have "normal" prototypal inheritance, this is like ng-include and ng-switch, so be wary of 2-way data binding to parent scope primitives, and child scope hiding/shadowing of parent scope properties.
3. scope: { ... } - the directive creates a new isolate/isolated scope. It does not prototypically inherit. This is usually your best choice when creating reusable components, since the directive cannot accidentally read or modify the parent scope. However, such directives often need access to a few parent scope properties. The object hash is used to set up two-way binding (using '=') or one-way binding (using '@') between the parent scope and the isolate scope. There is also '&' to bind to parent scope expressions. So, these all create local scope properties that are derived from the parent scope. Note that attributes are used to help set up the binding -- you can't just reference parent scope property names in the object hash, you have to use an attribute. E.g., this won't work if you want to bind to parent property parentProp in the isolated scope: <div my-directive> and scope: { localProp: '@parentProp' }. An attribute must be used to specify each parent property that the directive wants to bind to: <div my-directive the-Parent-Prop=parentProp> and scope: { localProp: '@theParentProp' }.
   Isolate scope's __proto__ references Object. Isolate scope's $parent references the parent scope, so although it is isolated and doesn't inherit prototypically from the parent scope, it is still a child scope.
   For the picture below we have
   <my-directive interpolated="{{parentProp1}}" twowayBinding="parentProp2"> and
   scope: { interpolatedProp: '@interpolated', twowayBindingProp: '=twowayBinding' }
   Also, assume the directive does this in its linking function: scope.someIsolateProp = "I'm isolated"
   
   For more information on isolate scopes see http://onehungrymind.com/angularjs-sticky-notes-pt-2-isolated-scope/
4. transclude: true - the directive creates a new "transcluded" child scope, which prototypically inherits from the parent scope. The transcluded and the isolated scope (if any) are siblings -- the $parent property of each scope references the same parent scope. When a transcluded and an isolate scope both exist, isolate scope property $$nextSibling will reference the transcluded scope. I'm not aware of any nuances with the transcluded scope.
   For the picture below, assume the same directive as above with this addition: transclude: true
   

This fiddle has a showScope() function that can be used to examine an isolate and transcluded scope. See the instructions in the comments in the fiddle.

Summary

There are four types of scopes:

1. normal prototypal scope inheritance -- ng-include, ng-switch, ng-controller, directive with scope: true
2. normal prototypal scope inheritance with a copy/assignment -- ng-repeat. Each iteration of ng-repeat creates a new child scope, and that new child scope always gets a new property.
3. isolate scope -- directive with scope: {...}. This one is not prototypal, but '=', '@', and '&' provide a mechanism to access parent scope properties, via attributes.
4. transcluded scope -- directive with transclude: true. This one is also normal prototypal scope inheritance, but it is also a sibling of any isolate scope.

For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via properties $parent and $$childHead and $$childTail.

Diagrams were generated with graphviz "*.dot" files, which are on github. Tim Caswell's "Learning JavaScript with Object Graphs" was the inspiration for using GraphViz for the diagrams.

public void selectImageAndResize(){    
    int returnVal = jFileChooser.showOpenDialog(this); //open jfilechooser
    if (returnVal == jFileChooser.APPROVE_OPTION) {    //select image
        File file = jFileChooser.getSelectedFile();    //get the image
        BufferedImage bi;
        try {
            //
            //transforms selected file to buffer
            //
            bi=ImageIO.read(file);  
            ImageIcon iconimage = new ImageIcon(bi);

            //
            //get image dimensions
            //
            BufferedImage bi2 = new BufferedImage(iconimage.getIconWidth(), iconimage.getIconHeight(), BufferedImage.TYPE_INT_ARGB); 
            Graphics g = bi.createGraphics();
            iconimage.paintIcon(null, g, 0,0);
            g.dispose();

            //
            //resize image according to jlabel
            //
            BufferedImage resizedimage=resize(bi,jLabel2.getWidth(), jLabel2.getHeight()); 
            ImageIcon resizedicon=new ImageIcon(resizedimage);
            jLabel2.setIcon(resizedicon);
        } catch (Exception ex) {
            System.out.println("problem accessing file"+file.getAbsolutePath());
        }
    }
    else {
        System.out.println("File access cancelled by user.");
    }
}

The difference is pretty subtle and if you dont pay much attention then you will keep it using in a wrong way.

Best way to understand the difference between orElse() and orElseGet() is that orElse() will always be executed if the Optional<T> is null or not, But orElseGet() will only be executed when Optional<T> is null.

The dictionary meaning of orElse is :- execute the part when something is not present, but here it contradicts, see the below example:

    Optional<String> nonEmptyOptional = Optional.of("Vishwa Ratna");
    String value = nonEmptyOptional.orElse(iAmStillExecuted());

    public static String iAmStillExecuted(){
    System.out.println("nonEmptyOptional is not NULL,still I am being executed");
    return "I got executed";
    }

Output: nonEmptyOptional is not NULL,still I am being executed

    Optional<String> emptyOptional = Optional.ofNullable(null);
    String value = emptyOptional.orElse(iAmStillExecuted());
    public static String iAmStillExecuted(){
    System.out.println("emptyOptional is NULL, I am being executed, it is normal as 
    per dictionary");
    return "I got executed";
    }

Output: emptyOptional is NULL, I am being executed, it is normal as per dictionary

For orElseGet() , The method goes as per dictionary meaning, The orElseGet() part will be executed only when the Optional is null.

Remarks: orElseGet() has clearly outperformed orElse() for our particular example.

Hope it clears the doubts of people like me who wants the very basic ground example :)

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt

just change your JDK I installed the JDK of SUN not Oracle and it works for me....

Visual Studio 2008 has some very good JavaScript debugging tools. You can drop a breakpoint in your client side JavaScript code and step through it using the exact same tools as you would the server side code. There is no need to attach to a process or do anything tricky to enable it.

Please take a good look here: http://jquerymobile.com/test/docs/api/methods.html

$.mobile.changePage() is to change from one page to another, and the parameter can be a url or a page object. ( only #result will also work )

$.mobile.page() isn't recommended anymore, please use .trigger( "create"), see also: JQuery Mobile .page() function causes infinite loop?

Important: Create vs. refresh: An important distinction

Note that there is an important difference between the create event and refresh method that some widgets have. The create event is suited for enhancing raw markup that contains one or more widgets. The refresh method that some widgets have should be used on existing (already enhanced) widgets that have been manipulated programmatically and need the UI be updated to match.

For example, if you had a page where you dynamically appended a new unordered list with data-role=listview attribute after page creation, triggering create on a parent element of that list would transform it into a listview styled widget. If more list items were then programmatically added, calling the listview’s refresh method would update just those new list items to the enhanced state and leave the existing list items untouched.

$.mobile.refresh() doesn't exist i guess

So what are you using for your results? A listview? Then you can update it by doing:

$('ul').listview('refresh');

Example: http://operationmobile.com/dont-forget-to-call-refresh-when-adding-items-to-your-jquery-mobile-list/

Otherwise you can do:

$('#result').live("pageinit", function(){ // or pageshow
    // your dom manipulations here
});

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

>>> import matplotlib.pyplot as plt
>>> a = [1,3,5,7]
>>> b = [11,-2,4,19]
>>> plt.pyplot.scatter(a,b)
>>> plt.scatter(a,b)
<matplotlib.collections.PathCollection object at 0x00000000057E2CF8>
>>> plt.show()
>>> c = [1,3,2,1]
>>> plt.errorbar(a,b,yerr=c, linestyle="None")
<Container object of 3 artists>
>>> plt.show()

where a is your x data b is your y data c is your y error if any

note that c is the error in each direction already

dict.items()

Does the trick.

I had the same problem with openCV on Raspberry Pi... don't know if this can solve your problem, but what worked for me was

import time
import cv2


cap = cv2.VideoCapture(0)

cap.set(3,1280)

cap.set(4,1024)

time.sleep(2)

cap.set(15, -8.0)

the time you have to use can be different

The easiest approach which I have used is

var found = arr.find(function(element) {
         return element.name === "k1";
 });

//If you print the found :
console.log(found);
=> Object { name: "k1", value: "abc" }

//If you need the value
console.log(found.value)
=> "abc"

The similar approach can be used to find the values from the JSON Array based on any input data from the JSON.

SOLUTION ONE

$this->db->where('id', '3');
// here we select every column of the table
$q = $this->db->get('my_users_table');
$data = $q->result_array();

echo($data[0]['age']);

SOLUTION TWO

// here we select just the age column
$this->db->select('age');
$this->db->where('id', '3');
$q = $this->db->get('my_users_table');
$data = $q->result_array();

echo($data[0]['age']);

SOLUTION THREE

$this->db->select('age');
$this->db->where('id', '3');
$q = $this->db->get('my_users_table');
// if id is unique, we want to return just one row
$data = array_shift($q->result_array());

echo($data['age']);

SOLUTION FOUR (NO ACTIVE RECORD)

$q = $this->db->query('SELECT age FROM my_users_table WHERE id = ?',array(3));
$data = array_shift($q->result_array());
echo($data['age']);

If you don't want all of your SQL statements to be echoed, but you only want to see the easily identifiable results of your script, do it this way:

set echo on

REM MyFirstTable

set echo off

delete from MyFirstTable;

set echo on

REM MySecondTable

set echo off

delete from MySecondTable;

The output from the above example will look something like this:

-REM MyFirstTable

13 rows deleted.

-REM MySecondTable

27 rows deleted.

Common Table Expressions let you define what are essentially views that last only within the scope of your select, insert, update and delete statements. Depending on what you need to do they can be terribly useful.

$("#message > span").text("your text");

or

$("#message").find("span").text("your text");

or

$("span","#message").text("your text");

or

$("#message > a.close-notify").siblings('span').text("your text");

To upgrade any python package, use pip install <pkg_name> --upgrade.

So in your case it would be pip install tensorflow --upgrade. Just updated to 1.1.0

I would definitely split them. It would be easy to sort the numbers by area code and contry code. But even if you're not going to split, just insert the numbers into the DB in one certain format. e.g. 1-555-555-1212 Your client side will be thankfull for not making it reformat your numbers.

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

It's possibly a 32 - 64 bits mismatch.

If you're running on a 64-bit OS, the Assembly RevitAPI may be compiled as 32-bit and your process as 64-bit or "Any CPU".

Or, the RevitAPI is compiled as 64-bit and your process is compiled as 32-bit or "Any CPU" and running on a 32-bit OS.

if you are working with JTextField then it can be helpfull..

public JTextField display;
String number=e.getActionCommand();

display.setText(display.getText()+number);

ch=number.toCharArray();
for( int i=0; i<ch.length; i++)
    System.out.println("in array a1= "+ch[i]);

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       <whatever>
   else:
       raise

If using bash, there's no need for external commands like sed, basename, rename, expr, etc.

for file in *.html
do
  mv "$file" "${file%.html}.txt"
done

Print lines where the third field is either snow or snowman only:

awk '$3~/^snow(man)?$/' file

After a lot of research, I finally figured this one out.

DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
   // Code you want to be delayed
}

This creates the desired "wait" effect in Swift 3 and Swift 4.

Inspired by a part of this answer.

This worked for me using sed [Edit: comment below points out sed doesn't support \s]

[^ ]

while

[^\s] 

didn't

# Delete everything except space and 'g'
echo "ghai ghai" | sed "s/[^\sg]//g"
gg

echo "ghai ghai" | sed "s/[^ g]//g"
g g

Regarding error: log4j:ERROR Element type "rollingPolicy" must be declared

1. Use a log4j.jar version newer than log4j-1.2.14.jar, which has a log4j.dtd defining rollingPolicy.
2. of course you also need apache-log4j-extras-1.1.jar
3. Check if any other third party jars you are using perhaps have an older version of log4j.jar packed inside. If so, make sure your log4j.jar comes first in the order before the third party containing the older log4j.jar.

Demo :

<connectionStrings>
<add name="myConnectionString" connectionString="server=localhost;database=myDb;uid=myUser;password=myPass;" />
</connectionStrings>

Based on your question:

<connectionStrings>
    <add name="itmall" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
    </connectionStrings>

Refer links:

http://www.connectionstrings.com/store-connection-string-in-webconfig/

Retrive connection string from web.config file:

write the below code in your file where you want;

string connstring=ConfigurationManager.ConnectionStrings["itmall"].ConnectionString;

SqlConnection con = new SqlConnection(connstring);

or you can go in your way like

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["itmall"].ConnectionString);

Note:

The "name" which you gave in web.config file and name which you used in connection string must be same(like "itmall" in this solution.)

Here is PostgreSQL example without trigger if someone need it on PostgreSQL:

CREATE SEQUENCE messages_seq;

 CREATE TABLE IF NOT EXISTS messages (
    id CHAR(20) NOT NULL DEFAULT ('message_' || nextval('messages_seq')),
    name CHAR(30) NOT NULL,
);

ALTER SEQUENCE messages_seq OWNED BY messages.id;

If you have to use the Handler, but you are into another thread, you can use runonuithread to run the handler in UI thread. This will save you from Exceptions thrown asking to call Looper.Prepare()

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                //Do something after 1 second
            }
        }, 1000);
    }
});

Looks quite messy, but this is one of the way.

`CREATE TRIGGER `category_before_ins_tr` BEFORE INSERT ON `category`
  FOR EACH ROW
BEGIN
    **SET @tableId= (SELECT id FROM dummy LIMIT 1);**

END;`;

JsonLint is good for validating and formatting JSON.
