just add /FORCE as linker flag and you're all set.

for instance, if you're working on CMakeLists.txt. Then add following line:

SET(CMAKE_EXE_LINKER_FLAGS  "/FORCE")

            if (isMultipart) {
                // Create a factory for disk-based file items
                FileItemFactory factory = new DiskFileItemFactory();

                // Create a new file upload handler
                ServletFileUpload upload = new ServletFileUpload(factory);

                    // Parse the request
                    List items = upload.parseRequest(request);
                    Iterator iterator = items.iterator();
                    while (iterator.hasNext()) {
                        FileItem item = (FileItem) iterator.next();
                        if (!item.isFormField()) {
                            String fileName = item.getName();    
                            String root = getServletContext().getRealPath("/");
                            File path = new File(root + "/uploads");
                            if (!path.exists()) {
                                boolean status = path.mkdirs();
                            }

                            File uploadedFile = new File(path + "/" + fileName);
                            System.out.println(uploadedFile.getAbsolutePath());
                            item.write(uploadedFile);
                        }
                    }
                } catch (FileUploadException e) {

This error occurred for me when I mistakenly added a comment following a line continuation character in VB.Net. I removed the comment and the problem went away.

<maven.compiler.release> (not source & target)

Several of the other Answers show <maven.compiler.source> & <maven.compiler.target>. Both of these are now supplanted by the simpler single element: <maven.compiler.release>.

<maven.compiler.release>15</maven.compiler.release>

So this:

  <!--old-school-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>15</maven.compiler.source>
    <maven.compiler.target>15</maven.compiler.target>
  </properties>

…becomes:

  <!--modern-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.release>15</maven.compiler.release>
  </properties>

See Question, “maven.compiler.release” as an replacement for source and target?

From http://en.wikipedia.org/wiki/CDATA:

Since it is useful to be able to use less-than signs (<) and ampersands (&) in web page scripts, and to a lesser extent styles, without having to remember to escape them, it is common to use CDATA markers around the text of inline and elements in XHTML documents. But so that the document can also be parsed by HTML parsers, which do not recognise the CDATA markers, the CDATA markers are usually commented-out, as in this JavaScript example:

<script type="text/javascript">
//<![CDATA[
document.write("<");
//]]>
</script>

Use the span tag

<style>
    .redText
    {
        color:red;
    }
    .blackText
    {
        color:black;
        font-weight:bold;
    }
</style>

<span class="redText">My Name is:</span>&nbsp;<span class="blackText">Tintincute</span>

It's also a good idea to avoid inline styling. Use a custom CSS class instead.

Cron does not load the user's profile when running a task and you have to include the profile in your shell script explicitly.

Example documentation

I had difficulty with this problem as well. I code mainly in Actionscript 3.0 which is base coding for the Adobe Flash Platform, but there are simularities in the Languages:

The solution I came up with is the following:

//Code for Rounding to the nearest 0.05
var r:Number = Math.random() * 10;  // NUMBER - Input Your Number here
var n:int = r * 10;   // INTEGER - Shift Decimal 2 places to right
var f:int = Math.round(r * 10 - n) * 5;// INTEGER - Test 1 or 0 then convert to 5
var d:Number = (n + (f / 10)) / 10; //  NUMBER - Re-assemble the number

trace("ORG No: " + r);
trace("NEW No: " + d);

Thats pretty much it. Note the use of 'Numbers' and 'Integers' and the way they are processed.

Good Luck!

the easiest way is to use position:absolute on both elements. You can absolutely position relative to the page, or you can absolutely position relative to a container div by setting the container div to position:relative

<div id="container" style="position:relative;">
    <div id="div1" style="position:absolute; top:0; left:0;"></div>
    <div id="div2" style="position:absolute; top:0; left:0;"></div>
</div>

This is my solution to the problem

const _ = require('lodash');

var objects = [{ 'x': 1, 'y': 2, 'z':3, a:{b:1, c:2, d:{n:0}}, p:[1, 2, 3]  }, { 'x': 2, 'y': 1, z:3, a:{b:2, c:2,d:{n:1}}, p:[1,3], m:3  }];

const diffFn=(a,b, path='')=>_.reduce(a, function(result, value, key) {

    if(_.isObjectLike(value)){
      if(_.isEqual(value, b[key])){
        return result;
      }else{

return result.concat(diffFn(value, b[key], path?(`${path}.${key}`):key))
      }
    }else{
return _.isEqual(value, b[key]) ?
        result : result.concat(path?(`${path}.${key}`):key);
    }
    
}, []);

const diffKeys1=diffFn(objects[0], objects[1])
const diffKeys2=diffFn(objects[1], objects[0])
const diffKeys=_.union(diffKeys1, diffKeys2)
const res={};

_.forEach(diffKeys, (key)=>_.assign(res, {[key]:{ old: _.get(objects[0], key), new:_.get(objects[1], key)} }))

res
/*
Returns
{
  x: { old: 1, new: 2 },
  y: { old: 2, new: 1 },
  'a.b': { old: 1, new: 2 },
  'a.d.n': { old: 0, new: 1 },
  'p.1': { old: 2, new: 3 },
  'p.2': { old: 3, new: undefined },
  m: { old: undefined, new: 3 }
}
*/

Several people seem to have the same problem. The issue is that the IDE only displays the preview if editing a layout file in the res/layout* directory of an Android project.

In particular, it won't show if editing a file in build/res/layout* since those are not source directory but output directory. In your case, you are editing a file in the build/ directory...

The Resource folder is set automatically, and can be viewed (and changed) in Project Structure > Modules > [Module name] > Android > Resources directory.

Unless you want to do something more complicated, feeding data from a HTML form into Flask is pretty easy.

• Create a view that accepts a POST request (my_form_post).
• Access the form elements in the dictionary request.form.

templates/my-form.html:

<form method="POST">
    <input name="text">
    <input type="submit">
</form>

from flask import Flask, request, render_template

app = Flask(__name__)

@app.route('/')
def my_form():
    return render_template('my-form.html')

@app.route('/', methods=['POST'])
def my_form_post():
    text = request.form['text']
    processed_text = text.upper()
    return processed_text

This is the Flask documentation about accessing request data.

If you need more complicated forms that need validation then you can take a look at WTForms and how to integrate them with Flask.

Note: unless you have any other restrictions, you don't really need JavaScript at all to send your data (although you can use it).

I managed to solved this by adding FcgidBusyTimeout . Just in case if anyone have similar issue with me.

Here is my settings on my apache.conf:

<VirtualHost *:80>
.......
<IfModule mod_fcgid.c>
FcgidBusyTimeout 3600
</IfModule>
</VirtualHost>

Command to install GCC and Development Tools on a CentOS / RHEL 7 server

Type the following yum command as root user:

yum group install "Development Tools"

OR

sudo yum group install "Development Tools"

If above command failed, try:

yum groupinstall "Development Tools"

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

simple solution from my end is to keep another Table with border and insert your table in the outer table.

<table border="1">
<tr>
    <td>
        <table border="0">
            <tr>
                <td>one</td>
                <td>two</td>
            </tr>
            <tr>
                <td>one</td>
                <td>two</td>
            </tr>
        </table>
    </td>
</tr>

</table>

When installing a tool globally it's to be used by a user as a command line utility anywhere, including outside of node projects. Global installs for a node project are bad because they make deployment more difficult.

npm 5.2+

The npx utility bundled with npm 5.2 solves this problem. With it you can invoke locally installed utilities like globally installed utilities (but you must begin the command with npx). For example, if you want to invoke a locally installed eslint, you can do:

npx eslint .

npm < 5.2

When used in a script field of your package.json, npm searches node_modules for the tool as well as globally installed modules, so the local install is sufficient.

So, if you are happy with (in your package.json):

"devDependencies": {
    "gulp": "3.5.2"
}
"scripts": {
    "test": "gulp test"
}

etc. and running with npm run test then you shouldn't need the global install at all.

Both methods are useful for getting people set up with your project since sudo isn't needed. It also means that gulp will be updated when the version is bumped in the package.json, so everyone will be using the same version of gulp when developing with your project.

Addendum:

It appears that gulp has some unusual behaviour when used globally. When used as a global install, gulp looks for a locally installed gulp to pass control to. Therefore a gulp global install requires a gulp local install to work. The answer above still stands though. Local installs are always preferable to global installs.

If you think about it, a body XRay scan (at the medical center) too needs this kind of measurement for estimating size of tumors. So they place a 1 Dollar Coin on the body, to do a comparative measurement.

Even newspaper is printed with some marks on the corners.

You need a reference to measure. May be you can get your person to wear a cap which has a few bright green circles. Once you recognize the size of the circle you can comparatively measure the remaining.

Or you can create a transparent 1 inch circle which will superimpose on the face, move the camera toward/away the face, aim your superimposed circle on that bright green circle on the cap. Then on your photo will be as per scale.

You can simply do:

"123456".Select(q => new string(q,1)).ToArray();

to have an enumerable of integers, as per comment request, you can:

"123456".Select(q => int.Parse(new string(q,1))).ToArray();

It is a little weak since it assumes the string actually contains numbers.

Please note, the way that build parameters are accessed inside pipeline scripts (pipeline plugin) has changed. This approach:

getBinding().hasVariable("MY_PARAM")

Is not working anymore. Please try this instead:

def myBool = env.getEnvironment().containsKey("MY_BOOL") ? Boolean.parseBoolean("$env.MY_BOOL") : false

The error message should tell you which application is already using the port - in my case it was explorer.exe, so it was just a case of restarting explorer from task manager.

What should happen if there are more than 1 longest string (think '12', and '01')?

Try that to get the longest element

max_length,longest_element = max([(len(x),x) for x in ('a','b','aa')])

And then regular foreach

for st in mylist:
    if len(st)==max_length:...

Works for me on a mysql database also:

Entity\Entity_name:
    type: entity
    table: table_name
    fields: 
        field_name:
            type: integer
            nullable: true
            options:
                default: 1

ExecuteScalar(); will work, but an output parameter would be a superior solution.

As mentioned by @jerry you can add services with the below command.

update-rc.d <service> defaults
update-rc.d <service> start 20 3 4 5
update-rc.d -f <service>  remove

To validate them check the above commands you can check /etc/rc*.d/ directory where service start with "k" means it will not execute during the boot and service start with "S" will start during the boot.

# for runlevel symlinks:
ls /etc/rc*.d/

In the below screenshot you can see apache2 starting in runlevel2(S02apache2) and stopping in runlevel1(K01apache2)

You can also check the service status with the below command where "+" means service is in running state "-" is in stopped.

service --status-all

OR

install sysv-rc-conf utility.

apt-get install sysv-rc-conf
example
sysv-rc-conf --level 2345 apach22 on
man sysv-rc-conf

Adding my solution for Net Framework and NetCore.

I used this for my Net Framework implementation:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( typeof( DescriptionAttribute ), false );

        // return description
        return attributes.Any() ? ( (DescriptionAttribute)attributes.ElementAt( 0 ) ).Description : "Description Not Found";
    }
}

This doesn't work for NetCore so I modified it to do this:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( false );

        // Description is in a hidden Attribute class called DisplayAttribute
        // Not to be confused with DisplayNameAttribute
        dynamic displayAttribute = null;

        if (attributes.Any())
        {
            displayAttribute = attributes.ElementAt( 0 );
        }

        // return description
        return displayAttribute?.Description ?? "Description Not Found";
    }
}

Enumeration Example:

public enum ExportTypes
{
    [Display( Name = "csv", Description = "text/csv" )]
    CSV = 0
}

Sample Usage for either static added:

var myDescription = myEnum.Description();

Use the xattr command. You can inspect the extended attributes:

$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine

and use the -d option to delete one extended attribute:

$ xattr -d com.apple.quarantine s.7z
$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms

you can also use the -c option to remove all extended attributes:

$ xattr -c s.7z
$ xattr s.7z

xattr -h will show you the command line options, and xattr has a man page.

You can compare both approaches for the same data:

def myGeneratorList(n):
    for i in range(n):
        yield i

def myIterableList(n):
    ll = n*[None]
    for i in range(n):
        ll[i] = i
    return ll

# Same values
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)
for i1, i2 in zip(ll1, ll2):
    print("{} {}".format(i1, i2))

# Generator can only be read once
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)

print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))

# Generator can be read several times if converted into iterable
ll1 = list(myGeneratorList(10))
ll2 = myIterableList(10)

print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))

Besides, if you check the memory footprint, the generator takes much less memory as it doesn't need to store all the values in memory at the same time.

This is the simplest way to do it. Allows for group authorities, as well as user authorities.

-- Postgres syntax

create table users (
  user_id serial primary key,
  enabled boolean not null default true,
  password text not null,
  username citext not null unique
);

create index on users (username);

create table groups (
  group_id serial primary key,
  name citext not null unique
);

create table authorities (
  authority_id serial primary key,
  authority citext not null unique
);

create table user_authorities (
  user_id int references users,
  authority_id int references authorities,
  primary key (user_id, authority_id)
);

create table group_users (
  group_id int references groups,
  user_id int referenecs users,
  primary key (group_id, user_id)
);

create table group_authorities (
  group_id int references groups,
  authority_id int references authorities,
  primary key (group_id, authority_id)
);

Then in META-INF/applicationContext-security.xml

<beans:bean class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" id="passwordEncoder" />

<authentication-manager>
    <authentication-provider>

        <jdbc-user-service
                data-source-ref="dataSource"

                users-by-username-query="select username, password, enabled from users where username=?"

                authorities-by-username-query="select users.username, authorities.authority from users join user_authorities using(user_id) join authorities using(authority_id) where users.username=?"

                group-authorities-by-username-query="select groups.id, groups.name, authorities.authority from users join group_users using(user_id) join groups using(group_id) join group_authorities using(group_id) join authorities using(authority_id) where users.username=?"

                />

          <password-encoder ref="passwordEncoder" />

    </authentication-provider>
</authentication-manager>

SELECT IF((
     SELECT count(*) FROM gdata_calendars 
     WHERE `group` =  ? AND id = ?)
,1,0);

API 11 added a setRotation() method to all views.

If you don't want to add a new dependency just to do this (like HTMLEntities) and you're already using Hpricot, it can both escape and unescape for you. It handles much more than CGI:

Hpricot.uxs "foo bär"
=> "foo bär"

You can either branch gh-pages to run your code or try this extension (Chrome, Firefox): https://github.com/ryt/githtml

If what you need are tests, you could embed your JS files into: http://jsperf.com/

Below applies to all tags with the following two classes

.abc.xyz {  
  width: 200px !important;
}

applies to div tags with the following two classes

div.abc.xyz {  
  width: 200px !important;
}

If you wanted to modify this using jQuery

$(document).ready(function() {
  $("div.abc.xyz").width("200px");
});

try below approach, very simple easy to implement

Prior to running python, type cd in the commmand line, and it will tell you the directory you are currently in. When python runs, it can only access files in this directory. hello.py needs to be in this directory, so you can move hello.py from its existing location to this folder as you would move any other file in Windows or you can change directories and run python in the directory hello.py is.

Edit: Python cannot access the files in the subdirectory unless a path to it provided. You can access files in any directory by providing the path. python C:\Python27\Projects\hello.p

Because Convert.ToInt32 rounds:

Return Value: rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.

...while the cast truncates:

When you convert from a double or float value to an integral type, the value is truncated.

Update: See Jeppe Stig Nielsen's comment below for additional differences (which however do not come into play if score is a real number as is the case here).

Oracle syntax from the 11g Documentation:

CASE { simple_case_expression | searched_case_expression }
     [ else_clause ]
     END

simple_case_expression

expr { WHEN comparison_expr THEN return_expr }...

searched_case_expression

{ WHEN condition THEN return_expr }...

else_clause

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD your certificate, then RUN update-ca-certificates. This way you will have a consistent state each time you start a container from this new image.

# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates

Let's say a docker build against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID, the container started by that command will have your certificate info. Simple and reproducible.

You can simply replace all \n with <br/> tag so that when page is displayed then it breaks line.

While @Jared's answer for incrementing works for 0.5 step size, it fails for other step sizes due to rounding issues:

# [11.0,11.1,11.2,11.299999999999999, ...   16.79999999999998, 16.899999999999977]

Instead I needed something like this myself, working not just for 0.5:

# Example 11->16 step 0.5
s = 11
e = 16
step = 0.5
my_list = [round(num, 2) for num in np.linspace(s,e,(e-s)*int(1/step)+1).tolist()]
# [11.0, 11.5, 12.0, 12.5, 13.0, 13.5, 14.0, 14.5, 15.0, 15.5, 16.0]

# Example 0->1 step 0.1
s = 0
e = 1
step = 0.1
my_list = [round(num, 2) for num in np.linspace(s,e,(e-s)*int(1/step)+1).tolist()]
# [0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0]

I normally differentiate these two via this diagram:

Use PrimaryKeyJoinColumn

Use JoinColumn

Whilst the listed answer is correct, may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly.

In my case this amounted to defining my column as:

`tag` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ''

This is in my opinion preferential to adjusting your queries.

If you want to do something to each row in a DataFrame object, use map. This will allow you to perform further calculations on each row. It's the equivalent of looping across the entire dataset from 0 to len(dataset)-1.

Note that this will return a PipelinedRDD, not a DataFrame.

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

Very easy, trial and error. Go to the cell you want the month in. Type the Month, go to the next cell and type the year, something weird will come up but then go to your number section click on the little arrow in the right bottom and highlight text and it will change to the year you originally typed

You can add atom beauty package for formatting text in atom..

file --> setting --> Install

then you type atom-beautify in search area.

then click Package button.. select atom beuty and install it.

next you can format your text using (Alt + ctrl + b) or right click and select beautify editor contents

From VS:

1. Open Team Explorer
2. Click Source Control Explorer
3. In the nav bar of the tool window there is a drop down labeled "Workspaces".
4. Extend it and click on the "Workspaces..." option (yeah, a bit un-intuitive)
5. The "Manage Workspaces" window comes up. Click edit and you can add / remove / edit your workspace

From VS on a different machine

You don't need VS to be on the same machine as the enlistment as you can edit remote enlistments! In the dialog that comes up when you press the "Workspaces..." item there is a check box stating "Show Remote Workspaces" - just tick that and you'll get a list of all your enlistments:

From the command line

Call "tf workspace" from a developer command prompt. It will bring up the "Manage Workspaces" directly!

Your best option is to call System.gc() which simply is a hint to the garbage collector that you want it to do a collection. There is no way to force and immediate collection though as the garbage collector is non-deterministic.

use Date function directly. Hope it works

It's not entirely clear what you mean by "the filepath of the file that is currently running within the process". sys.argv[0] usually contains the location of the script that was invoked by the Python interpreter. Check the sys documentation for more details.

As @Tim and @Pat Notz have pointed out, the __file__ attribute provides access to

the file from which the module was loaded, if it was loaded from a file

This worked for me:

git log
`git reset --hard <089810b5be5e907ad9e3b01f>`
git pull
git status

I need to do the same thing for a project I am currently working on. Here is how I solved things:

/* Prompt user for input */
printf("Enter a number: ");

/* Read user input */
char input[255]; //Of course, you can choose a different input size
fgets(input, sizeof(input), stdin);

/* Strip trailing newline */
size_t ln = strlen(input) - 1;
if( input[ln] == '\n' ) input[ln] = '\0';

/* Ensure that input is a number */
for( size_t i = 0; i < ln; i++){
    if( !isdigit(input[i]) ){
        fprintf(stderr, "%c is not a number. Try again.\n", input[i]);
        getInput(); //Assuming this is the name of the function you are using
        return;
    }
}

Guys I found the issue

I just tried by adding the qualifier name in employee service finally it solved my issue.

@Service("employeeService")

public class EmployeeServiceImpl implements EmployeeService{

}

As explained in other answers it converts the variable to a number. Specially useful when d can be either a number or a string that evaluates to a number.

Example (using the addMonths function in the question):

addMonths(34,1,true);
addMonths("34",1,true);

then the +d will evaluate to a number in all cases. Thus avoiding the need to check for the type and take different code paths depending on whether d is a number, a function or a string that can be converted to a number.

I had the same problem, Oracle config in default affects letter register. In exact my Scheme_Name was written all Capital letters. You can see your Scheme_Name on "Other Users" tab, if you are using Oracle S

• .exe - the 'normal' executable

• .vshost.exe - a special version of the executable to aid debuging; see MSDN for details

• .pdb - the Program Data Base with debug symbols

• .vshost.exe.manifest - a kind of configuration file containing mostly dependencies on libraries

I am using Linux raspi 4.19.118+ #1311 via ssh Powershell on Win 10 Pro 1909 with German keyboard. nano shortcut Goto Line with "Crtl + Shift + -" was not working Solution: Step 1 - Do Current Position with "Crtl + C" Step 2 - Goto Line with "Crtl + Shift + -" IS working!

I dont know what effects it. But now its working without step 1!

Alternatively you can use img2pdf to convert images to pdf. Install it on Debian or Ubuntu with:

sudo apt install img2pdf

Convert one or more images to pdf:

img2pdf img.jpg -o output.pdf

It uses a different mechanism than imagemagick to embed the image into the pdf. When possible Img2pdf embeds the image directly into the pdf, without decoding and recoding the image.

Things you can add to declarations: [] in modules

• Pipe
• Directive
• Component

Pro Tip: The error message explains it - Please add a @Pipe/@Directive/@Component annotation.

If you're doing programatic customisation, don't hard code the system font. Use UIFont systemFontOfSize:, UIFont boldSystemFontOfSize: and UIFont italicSystemFontOfSize (Apple documentation).

This has become especially relevant since iOS 7, which changed the system font to Helvetica Neue.

This has become super especially relevant since iOS 9, which changed the system font again to San Francisco.

You can use the following code to check if the file can be opened with exclusive access (that is, it is not opened by another application). If the file isn't closed, you could wait a few moments and check again until the file is closed and you can safely copy it.

You should still check if File.Copy fails, because another application may open the file between the moment you check the file and the moment you copy it.

public static bool IsFileClosed(string filename)
{
    try
    {
        using (var inputStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None))
        {
            return true;
        }
    }
    catch (IOException)
    {
        return false;
    }
}

In combination with the above answer, you want to ask jq for raw output, so your last filter should be eg.:

     cat input.json | jq -r 'keys'

From jq help:

     -r     output raw strings, not JSON texts;

You can add a callback function to your DatePicker to tell it to blur the input field before showing the DatePicker.

$('.selector').datepicker({
   beforeShow: function(){$('input').blur();}
});

Note: The iOS keyboard will appear for a fraction of a second and then hide.

You can also compare two different files in two different revisions, like this:

git diff <revision_1>:<file_1> <revision_2>:<file_2>

I wanted a text field that only allowed integers. Here's what I ended up with (using info from here and elsewhere):

Create integer number formatter (in UIApplicationDelegate so it can be reused):

@property (nonatomic, retain) NSNumberFormatter *integerNumberFormatter;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Create and configure an NSNumberFormatter for integers
    integerNumberFormatter = [[NSNumberFormatter alloc] init];
    [integerNumberFormatter setMaximumFractionDigits:0];

    return YES;
}

Use filter in UITextFieldDelegate:

@interface MyTableViewController : UITableViewController <UITextFieldDelegate> {
    ictAppDelegate *appDelegate;
}

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    // Make sure the proposed string is a number
    NSNumberFormatter *inf = [appDelegate integerNumberFormatter];
    NSString* proposedString = [textField.text stringByReplacingCharactersInRange:range withString:string];
    NSNumber *proposedNumber = [inf numberFromString:proposedString];
    if (proposedNumber) {
        // Make sure the proposed number is an integer
        NSString *integerString = [inf stringFromNumber:proposedNumber];
        if ([integerString isEqualToString:proposedString]) {
            // proposed string is an integer
            return YES;
        }
    }

    // Warn the user we're rejecting the change
    AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
    return NO;
}

private void _MenuExit_Click(object sender, RoutedEventArgs e)
{
   System.Windows.Application.Current.MainWindow.Close();
}

//Override the onClose method in the Application Main window

                                          MessageBoxButton.OKCancel);
    if (result == MessageBoxResult.Cancel)
    {
       e.Cancel = true;
    }
    base.OnClosing(e);
}

    mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
        @Override
        public void onMyLocationChange(Location location) {

                CameraUpdate center=CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
                CameraUpdate zoom=CameraUpdateFactory.zoomTo(11);
                mMap.moveCamera(center);
                mMap.animateCamera(zoom);

        }

After building the code, If we remove any line (For Example: In my case when I remove one Commented line this error was occur...) in debugging mode then the "Non-static method requires a target" error will occur.

Again, I tried to send the same request. This time code working properly. And I get the response properly in Postman.

I hope it will use to someone...

You can use .empty(), like this:

$("#foo").empty();

From the docs:

Remove all child nodes of the set of matched elements from the DOM.

I might be late. Simply add a new field ID in the table with type AutoNumber. This will generate unique IDs and can utilize in Access too

You would use the WITH ADMIN OPTION option in the GRANT statement

GRANT CREATE SESSION TO <<username>> WITH ADMIN OPTION

You'd obviously figure it out after a while but just posting this so that it might help someone. This could also happen when your file path contains any whitespace appended or prepended to it.

While it might be possible to use numpy alone to do this, the operation is not built-in. That said, you can use scikit-image (which is built on numpy) to do this kind of image manipulation.

Scikit-Image rescaling documentation is here.

For example, you could do the following with your image:

from skimage.transform import resize
bottle_resized = resize(bottle, (140, 54))

This will take care of things like interpolation, anti-aliasing, etc. for you.

TL;DR

if (a) b else c

^ is what you can use instead of the ternary operator expression a ? b : c which Kotlin syntax does not allow.

In Kotlin, many control statements, such as if, when, and even try, can be used as expressions. As a result, these statements can have a result which may be assigned to a variable, be returned from a function, etc.

Syntactically, there's no need for ternary operator

As a result of Kotlin's expressions, the language does not really need the ternary operator.

if (a) b else c

is what you can use instead of the ternary operator expression a ? b : c.

I think the idea is that the former expression is more readable since everybody knows what ifelse does, whereas ? : is rather unclear if you're not familiar with the syntax already.

Nevertheless, I have to admit that I often miss the more convenient ternary operator.

Other Alternatives

when

You might also see when constructs used in Kotlin when conditions are checked. It's also a way to express if-else cascades in an alternative way. The following corresponds to the OTs example.

when(a) {
    true -> b
    false -> c
}

Extensions

As many good examples (Kotlin Ternary Conditional Operator) in the other answers show, extensions can also help with solving your use case.

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

There was a time when adding strings into an array and finalising the string by using join was the fastest/best method. These days browsers have highly optimised string routines and it is recommended that + and += methods are fastest/best

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);     
    radioGroup.setOnClickListener(v -> {
                        // get selected radio button from radioGroup
                        int selectedId = radioGroup.getCheckedRadioButtonId();
                        // find the radiobutton by returned id
                        radioButton =  findViewById(selectedId);
                        String slectedValue=radioButton.getText()          
        });

Templates. I think that is Smarty syntax.

The simple way to get a date x days in the future is to increment the date:

function addDays(dateObj, numDays) {
  return dateObj.setDate(dateObj.getDate() + numDays);
}

Note that this modifies the supplied date object, e.g.

function addDays(dateObj, numDays) {
   dateObj.setDate(dateObj.getDate() + numDays);
   return dateObj;
}

var now = new Date();
var tomorrow = addDays(new Date(), 1);
var nextWeek = addDays(new Date(), 7);

alert(
    'Today: ' + now +
    '\nTomorrow: ' + tomorrow +
    '\nNext week: ' + nextWeek
);

I don't know jQuery, but I do know that if you get the select element, it contains an 'options' object.

var myOpts = document.getElementById('yourselect').options;
alert(myOpts[0].value) //=> Value of the first option

I almost always use curly-braces; however, in some cases where I'm writing tests, I do keyword packing/unpacking, and in these cases dict() is much more maintainable, as I don't need to change:

a=1,
b=2,

to:

'a': 1,
'b': 2,

It also helps in some circumstances where I think I might want to turn it into a namedtuple or class instance at a later time.

In the implementation itself, because of my obsession with optimisation, and when I don't see a particularly huge maintainability benefit, I'll always favour curly-braces.

In tests and the implementation, I would never use dict() if there is a chance that the keys added then, or in the future, would either:

• Not always be a string
• Not only contain digits, ASCII letters and underscores
• Start with an integer (dict(1foo=2) raises a SyntaxError)

The only "big" difference between POST & GET (when using them with AJAX) is since GET is URL provided, they are limited in ther length (since URL arent infinite in length).

String current = elements[i];
if (i != elements.length - 1) {
   String next = elements[i+1];
}

This makes sure you don't get an ArrayIndexOutOfBoundsException for the last element (there is no 'next' there). The other option is to iterate to i < elements.length - 1. It depends on your requirements.

If I want to create JavaScript Object from string generated by for loop then I would JSON to Object approach. I would generate JSON string by iterating for loop and then use any popular JavaScript Framework to evaluate JSON to Object.

I have used Prototype JavaScript Framework. I have two array with keys and values. I iterate through for loop and generate valid JSON string. I use evalJSON() function to convert JSON string to JavaScript object.

Here is example code. Tryout on your FireBug Console

var key = ["color", "size", "fabric"];
var value = ["Black", "XL", "Cotton"];

var json = "{ ";
for(var i = 0; i < key.length; i++) {
    (i + 1) == key.length ? json += "\"" + key[i] + "\" : \"" + value[i] + "\"" : json += "\"" + key[i] + "\" : \"" + value[i] + "\",";
}
json += " }";
var obj = json.evalJSON(true);
console.log(obj);

if (checkbox.checked && columnname != a && columnname != b && columnname != c)
    {
      "statement 1"
    }
else if (columnname != a && columnname != b && columnname != c 
        && columnname != A2)
    {
      "statement 1"
    }

is one way to simplify a little.

For me it worked like I had images in icons folder under src and I wrote below code.

new ImageIcon(getClass().getResource("/icons/rsz_measurment_01.png"));

In modern browsers you can build on top of @Sushil's answer with pure JavaScript and the DOM:

function validateEmail(value) {
  var input = document.createElement('input');

  input.type = 'email';
  input.required = true;
  input.value = value;

  return typeof input.checkValidity === 'function' ? input.checkValidity() : /\S+@\S+\.\S+/.test(value);
}

I've put together an example in the fiddle http://jsfiddle.net/boldewyn/2b6d5/. Combined with feature detection and the bare-bones validation from Squirtle's Answer, it frees you from the regular expression massacre and does not bork on old browsers.

Do you have your date variable stored as a String or a Date type?

In which case you will need to do something like

DateTime myDate = null;

DateTime.TryParse(myString,myDate);

or

Convert.ToDateTime(myString);

You can then call ToString("dd-MM-yyyy") on your date variable

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

There's a nice jQuery number plugin: https://github.com/teamdf/jquery-number

It allows you to change any number in the format you like, with options for decimal digits and separator characters for decimal and thousand:

$.number(12345.4556, 2);          // -> 12,345.46
$.number(12345.4556, 3, ',', ' ') // -> 12 345,456

You can use it inside input fields directly, which is nicer, using same options like above:

$("input").number(true, 2);

Or you can apply to a whole set of DOM elements using selector:

$('span.number').number(true, 2);

Use mouseup and keyup

$(":input").bind('keyup mouseup', function () {
    alert("changed");            
});

I think this should be a comment or an edit to ThinkingMedia's answer on this very question (Check free disk space for current partition in bash), but I am not allowed to comment (not enough rep) and my edit has been rejected (reason: "this should be a comment or an answer"). So please, powers of the SO universe, don't damn me for repeating and fixing someone else's "answer". But someone on the internet was wrong!™ and they wouldn't let me fix it.

The code

  df --output=avail -h "$PWD" | sed '1d;s/[^0-9]//g'

has a substantial flaw: Yes, it will output 50G free as 50 -- but it will also output 5.0M free as 50 or 3.4G free as 34 or 15K free as 15.

To create a script with the purpose of checking for a certain amount of free disk space you have to know the unit you're checking against. Remove it (as sed does in the example above) the numbers don't make sense anymore.

If you actually want it to work, you will have to do something like:

FREE=`df -k --output=avail "$PWD" | tail -n1`   # df -k not df -h
if [[ $FREE -lt 10485760 ]]; then               # 10G = 10*1024*1024k
     # less than 10GBs free!
fi;

Also for an installer to df -k $INSTALL_TARGET_DIRECTORY might make more sense than df -k "$PWD". Finally, please note that the --output flag is not available in every version of df / linux.

Here is an example:

$.ajax({
        type: "post",
        url: "ajax/example.php",
        data: 'page=' + btn_page,
        success: function (data) {
            var a = data; // This line shows error.
            $.ajax({
                type: "post",
                url: "example.php",
                data: 'page=' + a,
                success: function (data) {

                }
            });
        }
    });

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

There are some cool answers here (errator esp.), but for something analogous to split in other languages -- which is what I took the original question to mean -- I settled on this:

IN="[email protected];[email protected]"
declare -a a="(${IN/;/ })";

Now ${a[0]}, ${a[1]}, etc, are as you would expect. Use ${#a[*]} for number of terms. Or to iterate, of course:

for i in ${a[*]}; do echo $i; done

IMPORTANT NOTE:

This works in cases where there are no spaces to worry about, which solved my problem, but may not solve yours. Go with the $IFS solution(s) in that case.

$ readlink -m FILE
/path/to/FILE

This is better than readlink -e FILE or realpath, because it works even if the file doesn't exist.

C++ has two kinds of enum:

1. enum classes
2. Plain enums

Here are a couple of examples on how to declare them:

 enum class Color { red, green, blue }; // enum class
 enum Animal { dog, cat, bird, human }; // plain enum 

What is the difference between the two?

• enum classes - enumerator names are local to the enum and their values do not implicitly convert to other types (like another enum or int)

• Plain enums - where enumerator names are in the same scope as the enum and their values implicitly convert to integers and other types

Example:

enum Color { red, green, blue };                    // plain enum 
enum Card { red_card, green_card, yellow_card };    // another plain enum 
enum class Animal { dog, deer, cat, bird, human };  // enum class
enum class Mammal { kangaroo, deer, human };        // another enum class

void fun() {

    // examples of bad use of plain enums:
    Color color = Color::red;
    Card card = Card::green_card;

    int num = color;    // no problem

    if (color == Card::red_card) // no problem (bad)
        cout << "bad" << endl;

    if (card == Color::green)   // no problem (bad)
        cout << "bad" << endl;

    // examples of good use of enum classes (safe)
    Animal a = Animal::deer;
    Mammal m = Mammal::deer;

    int num2 = a;   // error
    if (m == a)         // error (good)
        cout << "bad" << endl;

    if (a == Mammal::deer) // error (good)
        cout << "bad" << endl;

}

Conclusion:

enum classes should be preferred because they cause fewer surprises that could potentially lead to bugs.

This error occurs when you're trying to target an element that is wrapped in a condition.

So, here if I use ngIf in place of [hidden], it will give me TypeError: Cannot read property 'nativeElement' of undefined

So use [hidden], class.show or class.hide in place of *ngIf.

<button (click)="displayMap()" class="btn btn-primary">Display Map</button>

   <div [hidden]="!display">
      <div #mapContainer id="map">Content to render when condition is true.</div>
   </div>

One way to achieve this is

>>> pd.DataFrame(np.array([[2, 3, 4]]), columns=['A', 'B', 'C']).append(df, ignore_index=True)
Out[330]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

Generally, it's easiest to append dataframes, not series. In your case, since you want the new row to be "on top" (with starting id), and there is no function pd.prepend(), I first create the new dataframe and then append your old one.

ignore_index will ignore the old ongoing index in your dataframe and ensure that the first row actually starts with index 1 instead of restarting with index 0.

Typical Disclaimer: Cetero censeo ... appending rows is a quite inefficient operation. If you care about performance and can somehow ensure to first create a dataframe with the correct (longer) index and then just inserting the additional row into the dataframe, you should definitely do that. See:

>>> index = np.array([0, 1, 2])
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[0:1] = [list(s1), list(s2)]
>>> df2
Out[336]: 
     A    B    C
0    5    6    7
1    7    8    9
2  NaN  NaN  NaN
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[1:] = [list(s1), list(s2)]

So far, we have what you had as df:

>>> df2
Out[339]: 
     A    B    C
0  NaN  NaN  NaN
1    5    6    7
2    7    8    9

But now you can easily insert the row as follows. Since the space was preallocated, this is more efficient.

>>> df2.loc[0] = np.array([2, 3, 4])
>>> df2
Out[341]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

If you want to retrieve POST data:

first_name = request.form.get("firstname")

If you want to retrieve GET (query string) data:

first_name = request.args.get("firstname")

Or if you don't care/know whether the value is in the query string or in the post data:

first_name = request.values.get("firstname") 

request.values is a CombinedMultiDict that combines Dicts from request.form and request.args.

You have a ; at the end of the if. Change:

  if (fp == NULL);
  return 0;

to

  if (fp == NULL) 
    return 0;

The MyKey class (@Embeddable) should not have any relationships like @ManyToOne

If you look at the documentation for the built-in errors, you'll see that most Exception classes assign their first argument as a message attribute. Not all of them do though.

Notably,EnvironmentError (with subclasses IOError and OSError) has a first argument of errno, second of strerror. There is no message... strerror is roughly analogous to what would normally be a message.

More generally, subclasses of Exception can do whatever they want. They may or may not have a message attribute. Future built-in Exceptions may not have a message attribute. Any Exception subclass imported from third-party libraries or user code may not have a message attribute.

I think the proper way of handling this is to identify the specific Exception subclasses you want to catch, and then catch only those instead of everything with an except Exception, then utilize whatever attributes that specific subclass defines however you want.

If you must print something, I think that printing the caught Exception itself is most likely to do what you want, whether it has a message attribute or not.

You could also check for the message attribute if you wanted, like this, but I wouldn't really suggest it as it just seems messy:

try:
    pass
except Exception as e:
    # Just print(e) is cleaner and more likely what you want,
    # but if you insist on printing message specifically whenever possible...
    if hasattr(e, 'message'):
        print(e.message)
    else:
        print(e)

The real trick is: Use a Backslash at the end of the target path where to copy the file. The /Y is for overwriting existing files, if you want no warnings.

Example:

xcopy /Y "C:\file\from\here.txt" "C:\file\to\here\"

_mkdir will also do the job.

_mkdir("D:\\test");

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

What about element.tagName?

See also tagName docs on MDN.

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

I don't know if you even need to wrap it. Won't this work?

SELECT COUNT(*), SUM(DATEDIFF(now(),availables.updated_at))
FROM availables
INNER JOIN rooms    ON availables.room_id=rooms.id
WHERE availables.bookdate BETWEEN '2009-06-25' 
  AND date_add('2009-06-25', INTERVAL 4 DAY)
  AND rooms.hostel_id = 5094
GROUP BY availables.bookdate);

If your goal is to return both result sets then you'll need to store it some place temporarily.

Simply using an outer directory for the output, solved the problem for me.

sudo tar czf ./../31OCT18.tar.gz ./

you can set PYTHONPATH, by os.environ['PATHPYTHON']=/some/path, then you need to call os.system('python') to restart the python shell to make the newly added path effective.

Is your type really arbitrary? If you know it is just going to be a int float or string you could just do

 if val.dtype == float and np.isnan(val):

assuming it is wrapped in numpy , it will always have a dtype and only float and complex can be NaN

If you want to style the output of a data frame in a jupyter notebook cell, you can set the display style on a per-dataframe basis:

df = pd.DataFrame({'A': np.random.randn(4)*1e7})
df.style.format("{:.1f}")

See the documentation here.

The existing answers posted either rely on the CLI utility flock or do not properly secure the lock file. The flock utility is not available on all non-Linux systems (i.e. FreeBSD), and does not work properly on NFS.

In my early days of system administration and system development, I was told that a safe and relatively portable method of creating a lock file was to create a temp file using mkemp(3) or mkemp(1), write identifying information to the temp file (i.e. PID), then hard link the temp file to the lock file. If the link was successful, then you have successfully obtained the lock.

When using locks in shell scripts, I typically place an obtain_lock() function in a shared profile and then source it from the scripts. Below is an example of my lock function:

obtain_lock()
{
  LOCK="${1}"
  LOCKDIR="$(dirname "${LOCK}")"
  LOCKFILE="$(basename "${LOCK}")"

  # create temp lock file
  TMPLOCK=$(mktemp -p "${LOCKDIR}" "${LOCKFILE}XXXXXX" 2> /dev/null)
  if test "x${TMPLOCK}" == "x";then
     echo "unable to create temporary file with mktemp" 1>&2
     return 1
  fi
  echo "$$" > "${TMPLOCK}"

  # attempt to obtain lock file
  ln "${TMPLOCK}" "${LOCK}" 2> /dev/null
  if test $? -ne 0;then
     rm -f "${TMPLOCK}"
     echo "unable to obtain lockfile" 1>&2
     if test -f "${LOCK}";then
        echo "current lock information held by: $(cat "${LOCK}")" 1>&2
     fi
     return 2
  fi
  rm -f "${TMPLOCK}"

  return 0;
};

The following is an example of how to use the lock function:

#!/bin/sh

. /path/to/locking/profile.sh
PROG_LOCKFILE="/tmp/myprog.lock"

clean_up()
{
  rm -f "${PROG_LOCKFILE}"
}

obtain_lock "${PROG_LOCKFILE}"
if test $? -ne 0;then
   exit 1
fi
trap clean_up SIGHUP SIGINT SIGTERM

# bulk of script

clean_up
exit 0
# end of script

Remember to call clean_up at any exit points in your script.

I've used the above in both Linux and FreeBSD environments.

Check this out... I just got this working and it seems exactly what you are trying to do as well.

2 functions. One to select the table and copy it to the clipboard, and the second writes it to excel en masse. Just call write_to_excel() and put in your table id (or modify it to take it as an argument).

  function selectElementContents(el) {
        var body = document.body, range, sel;
        if (document.createRange && window.getSelection) {
            range = document.createRange();
            sel = window.getSelection();
            sel.removeAllRanges();
            try {
                range.selectNodeContents(el);
                sel.addRange(range);
            } catch (e) {
                range.selectNode(el);
                sel.addRange(range);
            }
        } else if (body.createTextRange) {
            range = body.createTextRange();
            range.moveToElementText(el);
            range.select();
        }
        range.execCommand("Copy");
    }

function write_to_excel() 
{
var tableID = "AllItems";
selectElementContents( document.getElementById(tableID) );

var excel = new ActiveXObject("Excel.Application");
// excel.Application.Visible = true; 
var wb=excel.WorkBooks.Add();
var ws=wb.Sheets("Sheet1");
ws.Cells(1,1).Select;
ws.Paste;
ws.DrawingObjects.Delete;
ws.Range("A1").Select
 excel.Application.Visible = true; 
}

flex-grow - This defines the ability for a flex item to grow if necessary. It accepts a unitless value that serves as a proportion. It dictates what amount of the available space inside the flex container the item should take up.

If all items have flex-grow set to 1, the remaining space in the container will be distributed equally to all children. If one of the children has a value of 2, the remaining space would take up twice as much space as the others (or it will try to, at least). See more here

  display: flex;_x000D_

Import cars data

import pandas as pd

cars = pd.read_csv('cars.csv', index_col = 0)

Here is how the cars.csv file looks.

Print out drives_right column as Series:

print(cars.loc[:,"drives_right"])

    US      True
    AUS    False
    JAP    False
    IN     False
    RU      True
    MOR     True
    EG      True
    Name: drives_right, dtype: bool

The single bracket version gives a Pandas Series, the double bracket version gives a Pandas DataFrame.

Print out drives_right column as DataFrame

print(cars.loc[:,["drives_right"]])

         drives_right
    US           True
    AUS         False
    JAP         False
    IN          False
    RU           True
    MOR          True
    EG           True

Adding a Series to another Series creates a DataFrame.

You could make your own plugins.

jQuery.fn.visible = function() {
    return this.css('visibility', 'visible');
};

jQuery.fn.invisible = function() {
    return this.css('visibility', 'hidden');
};

jQuery.fn.visibilityToggle = function() {
    return this.css('visibility', function(i, visibility) {
        return (visibility == 'visible') ? 'hidden' : 'visible';
    });
};

If you want to overload the original jQuery toggle(), which I don't recommend...

!(function($) {
    var toggle = $.fn.toggle;
    $.fn.toggle = function() {
        var args = $.makeArray(arguments),
            lastArg = args.pop();

        if (lastArg == 'visibility') {
            return this.visibilityToggle();
        }

        return toggle.apply(this, arguments);
    };
})(jQuery);

jsFiddle.

In case any one stumbles upon this as I just have...

Find First blank cell in a column(I'm using column D but didn't want to include D1)

NextFree = Range("D2:D" & Rows.Count).Cells.SpecialCells(xlCellTypeBlanks).Row
Range("D" & NextFree).Select

NextFree is just a name, you could use sausages if you wanted.

To hide both letter e and minus sign - just go for:

onkeydown="return event.keyCode !== 69 && event.keyCode !== 189"

Use jQuery:

$("li").find("p").html()

should work.

The CSS table model is based on the HTML table model http://www.w3.org/TR/CSS21/tables.html

A table is divided into ROWS, and each row contains one or more cells. Cells are children of ROWS, they are NEVER children of columns.

"display: table-column" does NOT provide a mechanism for making columnar layouts (e.g. newspaper pages with multiple columns, where content can flow from one column to the next).

Rather, "table-column" ONLY sets attributes that apply to corresponding cells within the rows of a table. E.g. "The background color of the first cell in each row is green" can be described.

The table itself is always structured the same way it is in HTML.

In HTML (observe that "td"s are inside "tr"s, NOT inside "col"s):

<table ..>
  <col .. />
  <col .. />
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
</table>

Corresponding HTML using CSS table properties (Note that the "column" divs do not contain any contents -- the standard does not allow for contents directly in columns):

.mytable {_x000D_
  display: table;_x000D_
}_x000D_
.myrow {_x000D_
  display: table-row;_x000D_
}_x000D_
.mycell {_x000D_
  display: table-cell;_x000D_
}_x000D_
.column1 {_x000D_
  display: table-column;_x000D_
  background-color: green;_x000D_
}_x000D_
.column2 {_x000D_
  display: table-column;_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 1</div>_x000D_
    <div class="mycell">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 2</div>_x000D_
    <div class="mycell">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

OPTIONAL: both "rows" and "columns" can be styled by assigning multiple classes to each row and cell as follows. This approach gives maximum flexibility in specifying various sets of cells, or individual cells, to be styled:

//Useful css declarations, depending on what you want to affect, include:_x000D_
_x000D_
/* all cells (that have "class=mycell") */_x000D_
.mycell {_x000D_
}_x000D_
_x000D_
/* class row1, wherever it is used */_x000D_
.row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 (if you've put "class=mycell" on each cell) */_x000D_
.row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 */_x000D_
.row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows */_x000D_
.cell1 {_x000D_
}_x000D_
_x000D_
/* row1 inside class mytable (so can have different tables with different styles) */_x000D_
.mytable .row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 of a mytable */_x000D_
.mytable .row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 of a mytable */_x000D_
.mytable .row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows of a mytable */_x000D_
.mytable .cell1 {_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow row1">_x000D_
    <div class="mycell cell1">contents of first cell in row 1</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow row2">_x000D_
    <div class="mycell cell1">contents of first cell in row 2</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

In today's flexible designs, which use <div> for multiple purposes, it is wise to put some class on each div, to help refer to it. Here, what used to be <tr> in HTML became class myrow, and <td> became class mycell. This convention is what makes the above CSS selectors useful.

PERFORMANCE NOTE: putting class names on each cell, and using the above multi-class selectors, is better performance than using selectors ending with *, such as .row1 * or even .row1 > *. The reason is that selectors are matched last first, so when matching elements are being sought, .row1 * first does *, which matches all elements, and then checks all the ancestors of each element, to find if any ancestor has class row1. This might be slow in a complex document on a slow device. .row1 > * is better, because only the immediate parent is examined. But it is much better still to immediately eliminate most elements, via .row1 .cell1. (.row1 > .cell1 is an even tighter spec, but it is the first step of the search that makes the biggest difference, so it usually isn't worth the clutter, and the extra thought process as to whether it will always be a direct child, of adding the child selector >.)

The key point to take away re performance is that the last item in a selector should be as specific as possible, and should never be *.

Reading the R language documentation, as.integer has more to do with how the number is stored than if it is practically equivalent to an integer. is.integer tests if the number is declared as an integer. You can declare an integer by putting a L after it.

> is.integer(66L)
[1] TRUE
> is.integer(66)
[1] FALSE

Also functions like round will return a declared integer, which is what you are doing with x==round(x). The problem with this approach is what you consider to be practically an integer. The example uses less precision for testing equivalence.

> is.wholenumber(1+2^-50)
[1] TRUE
> check.integer(1+2^-50)
[1] FALSE

So depending on your application you could get into trouble that way.

js

var el = document.getElementById("el");
el.scrollTop = el.scrollHeight - el.scrollTop;

$('#my_select option:selected').attr('id');

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

In case you have an object logged:

• Right click on the object in console and click Store as a global variable
• the output will be something like temp1
• type in console copy(temp1)
• paste to your favorite text editor

It might be smart to also just create a new list if the current list item meets the desired criteria.

so:

for item in originalList:
   if (item != badValue):
        newList.append(item)

and to avoid having to re-code the entire project with the new lists name:

originalList[:] = newList

note, from Python documentation:

copy.copy(x) Return a shallow copy of x.

copy.deepcopy(x) Return a deep copy of x.

Should be probably changed to

firstName = firstName.trim().replaceAll("\\.", "");

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

My solution is just compilation of best ideas in thread, with a little improvement. I use both dedicated procedure (@Tomasz Borowiec) to facilitate reuse, and exception handling (@Tobias Twardon) to reduce code and to get rid of redundant table name in procedure.

By 'the wiz' I'm assuming you're talking about the 'SQL Server Import and Export Wizard'. (I'm also pretty new so I don't understand most questions, much less most answers, but I think I get this one). If so couldn't you take the spreadsheet, or a copy of it, delete the columns you don't want imported and then use the wizard?

I've always found the ability to do what I need with it and I'm only on SQL Server 2000 (not sure how other versions differ).

Edit: In fact I'm looking at it now and I seem to be able to choose which columns I want to map to which rows in an existing table. On the 'Select Source Tables and Views' screen I check the datasheet I'm using, select the 'Destination' then click the 'Edit...' button. From there you can choose the Excel column and the table column to map it to.

winpty works as long as you don't specify volumes to be mounted such as ".:/mountpoint" or "${pwd}:/mountpoint"

The best workaround I have found is to use the git-bash plugin inside Visual Code Studio and use the terminal to start and stop containers or docker-compose.

Sure there's an entity for tabs:

	

(The tab is ASCII character 9, or Unicode U+0009.)

However, just like literal tabs (ones you type in to your text editor), all tab characters are treated as whitespace by HTML parsers and collapsed into a single space except those within a <pre> block, where literal tabs will be rendered as 8 spaces in a monospace font.

jQuery's .show() and .hide() functions are probably your best bet.

if you're connecting to a postgres database, the following works:

result = cursor.execute(query)

if result.returns_rows:
    # we got rows!
    return [{k:v for k,v in zip(result.keys(), r)} for r in result.rows]
else:
    return None

mailx -a /path/to/file email@address

You might go into interactive mode (it will prompt you with "Subject: " and then a blank line), enter a subject, then enter a body and hit Ctrl+D (EOT) to finish.

ComponentWillReceiveProps() is going to be deprecated in the future due to bugs and inconsistencies. An alternative solution for re-rendering a component on props change is to use ComponentDidUpdate() and ShouldComponentUpdate().

ComponentDidUpdate() is called whenever the component updates AND if ShouldComponentUpdate() returns true (If ShouldComponentUpdate() is not defined it returns true by default).

shouldComponentUpdate(nextProps){
    return nextProps.changedProp !== this.state.changedProp;
}

componentDidUpdate(props){
    // Desired operations: ex setting state
}

This same behavior can be accomplished using only the ComponentDidUpdate() method by including the conditional statement inside of it.

componentDidUpdate(prevProps){
    if(prevProps.changedProp !== this.props.changedProp){
        this.setState({          
            changedProp: this.props.changedProp
        });
    }
}

If one attempts to set the state without a conditional or without defining ShouldComponentUpdate() the component will infinitely re-render

Happened to me today.

My issue was that I had too many tabs open (I didn't know they were open) with source code on them.

If you close all the tabs, maybe you will unconfuse IntelliJ into indexing the dependencies correctly

$('select').val()  // Get's the value

$('select option:selected').val() ; // Get's the value

$('select').find('option:selected').val() ; // Get's the value

$('select option:selected').text()  // Gets you the text of the selected option

I have created a user specific ssh-config, so my user automatically logs in with the correct credentials and key.

First I needed to generate an key-pair

ssh-keygen -t rsa -b 4096 -C "[email protected]"

and saved it to e.g ~/.ssh/id_my_domain. Note that this is also the keypair (private and public) I've connected to my Github account, so mine is stored in~/.ssh/id_github_com.

I have then created (or altered) a file called ~/.ssh/config with an entry:

Host github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_github_com

On another server, the "ssh-url" is [email protected]:username/private-repo.git and the entry for this server would have been:

Host domain.com
    HostName domain.com
    User admin
    IdentityFile ~/.ssh/id_domain_com

Just to clarify that you need ensure that the User, Host and HostName is set correctly.

Now I can just browse into the go path and then go get <package>, e.g go get main where the file main/main.go includes the package (from last example above) domain.com:username/private-repo.git.

Brother this piece of code is not a solution just change it to

<script type="text/javascript" language="javascript">
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
    function EndRequestHandler(sender, args){
        if (args.get_error() != undefined){
            **alert(args.get_error().message.substr(args.get_error().name.length + 2));**
            args.set_errorHandled(true);
        }
    }
</script>

and you will see the error is there but you are just not throwing it on UI.

New to the python world!
I need a System Time independent Stopwatch so I did translate my old C++ class into Python:

from ctypes.wintypes import DWORD
import win32api
import datetime

class Stopwatch:

    def __init__(self):
        self.Restart()

    def Restart(self):
        self.__ulStartTicks = DWORD(win32api.GetTickCount()).value

    def ElapsedMilliSecs(self):
        return DWORD(DWORD(win32api.GetTickCount()).value-DWORD(self.__ulStartTicks).value).value

    def ElapsedTime(self):
        return datetime.timedelta(milliseconds=self.ElapsedMilliSecs())

This has no 49 days run over issue due to DWORD math but NOTICE that GetTickCount has about 15 milliseconds granularity so do not use this class if your need 1-100 milliseconds elapsed time ranges.

Any improvement or feedback is welcome!

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

create shake.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" 
        android:toXDelta="10" 
            android:duration="1000" 
                android:interpolator="@anim/cycle" />

and cycle.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="4" />

now add animation on your code

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);

If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value

Seems you need to use JToggleButton :

JToggleButton tb = new JToggleButton("push me");
tb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        JToggleButton btn =  (JToggleButton) e.getSource();
        btn.setText(btn.isSelected() ? "pushed" : "push me");
    }
});

If we just do x.append(y), y gets referenced into x such that any changes made to y will affect appended x as well. So if we need to insert only elements, we should do following:

x = [1,2,3] y = [4,5,6] x.append(y[:])

This is how I have achieved it using purely CSS and HTML (no JavaScript/images etc.).

It gracefully degrades in most browsers (I do need to add in a fix for lack of last-of-type in < IE9).

Do you understand the concept of casting? Casting is the process of type conversion, which is in Java very common because its a statically typed language. Some examples:

Cast the String "1" to an int -> no problem

Cast the String "abc" to an int -> raises a ClassCastException

Or think of a class diagram with Animal.class, Dog.class and Cat.class

Animal a = new Dog();
Dog d = (Dog) a; // No problem, the type animal can be casted to a dog, because its a dog.
Cat c = (Dog) a; // Raises class cast exception; you can't cast a dog to a cat.

//for update

(from x in dataBase.Customers
         where x.Name == "Test"
         select x).ToList().ForEach(xx => xx.Name="New Name");

//for delete

dataBase.Customers.RemoveAll(x=>x.Name=="Name");

For concatenating it's:

input[name="Sex"][value="M"] {}

And for taking union it's:

input[name="Sex"], input[value="M"] {}

No. There is no way you can edit the result grid. The result grid is mainly for displaying purposes of the query you executed.

This for the reason that anybody can execute complex queries. Hopefully for the next release they will include this kind of functionality.

I Hope that answer your question.

Try the following to see if you have the proper repository installed:

# yum search java | grep 'java-'

This is going to return a list of available packages that have java in the title. Specifically we are interested in the java- anything, as the jdk will typically be in 'java-version#' type format... Anyhow, if you have to install a repo look at Dag Wieers repo:

http://dag.wieers.com/rpm/FAQ.php#B

After you've got it installed try yum search again... This time you'll have a bunch of java stuff.

# yum search java | grep 'java-'

This will return the list of the available java packages. You can install one like this:

# yum install java-1.7.0-openjdk.x86_64

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

Yes, quite straight forward:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set(ByVal value As String)
        _name = value
    End Set
End Property

As a slight improvement over the other answers, you can do the mkdir and chmod as a single operation using mkdir's -m switch.

$ mkdir -m 700 ${HOME}/.ssh

Usage

From a Linux system

$ mkdir --help
Usage: mkdir [OPTION]... DIRECTORY...
Create the DIRECTORY(ies), if they do not already exist.

Mandatory arguments to long options are mandatory for short options too.
  -m, --mode=MODE   set file mode (as in chmod), not a=rwx - umask
...

SELECT CONVERT(NVARCHAR(10), PaymentDate, 120) [Month], SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY CONVERT(NVARCHAR(10), PaymentDate, 120)
ORDER BY [Month]

You could also try:

SELECT DATEPART(Year, PaymentDate) Year, DATEPART(Month, PaymentDate) Month, SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY DATEPART(Year, PaymentDate), DATEPART(Month, PaymentDate)
ORDER BY Year, Month

According to new Swift 2.0 we should use do try catch. The code would look like this:

var badumSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("BadumTss", ofType: "mp3"))
var audioPlayer = AVAudioPlayer()
 do {
     player = try AVAudioPlayer(contentsOfURL: badumSound)
 } catch {
     print("No sound found by URL:\(badumSound)")
 }
 player.prepareToPlay()

Good working example here: http://jsfiddle.net/MrTest/t4NXD/62/

Plus:

• has nice fade in / fade out animation
• will pause on :hover
• will prevent running multiple actions (finish run animation before starting second)
• will prevent going broken when in the tab ( browser stops scripts in the tabs)

Tested and working!

You Can use Follow code Textbox Keypress Event:

Private Sub txtbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtbox1.KeyPress
    Try
        If Val(txtbox1.text) < 10 Then
            If Char.IsLetterOrDigit(e.KeyChar) = False And Char.IsControl(e.KeyChar) = False Then
                e.Handled = True
            End If
        Else
            e.Handled = True
        End If
    Catch ex As Exception
        ShowException(ex.Message, MESSAGEBOX_TITLE, ex)
    End Try
End Sub

This code allow numbers only and you can enter only number between 1 to 10.

You can use the :not filter selector:

$('foo:not(".someClass")')

Or not() method:

$('foo').not(".someClass")

For me, the only way on SQL 2008 R2 was this :

EXEC sp_configure 'Show Advanced Options', 1    
RECONFIGURE **WITH OVERRIDE**    
EXEC sp_configure 'xp_cmdshell', 1    
RECONFIGURE **WITH OVERRIDE**

The problem is in this line:

with pattern.findall(row) as f:

You are using the with statement. It requires an object with __enter__ and __exit__ methods. But pattern.findall returns a list, with tries to store the __exit__ method, but it can't find it, and raises an error. Just use

f = pattern.findall(row)

instead.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

sed -n '16224,16482p' < dump.sql

Content-Type: application/json is just the content header. The content header is just information about the type of returned data, ex::JSON,image(png,jpg,etc..),html.

Keep in mind, that JSON in JavaScript is an array or object. If you want to see all the data, use console.log instead of alert:

alert(response.text); // Will alert "[object Object]" string
console.log(response.text); // Will log all data objects

If you want to alert the original JSON content as a string, then add single quotation marks ('):

echo "'" . json_encode(array('text' => 'omrele')) . "'";
// alert(response.text) will alert {"text":"omrele"}

Do not use double quotes. It will confuse JavaScript, because JSON uses double quotes on each value and key:

echo '<script>var returndata=';
echo '"' . json_encode(array('text' => 'omrele')) . '"';
echo ';</script>';

// It will return the wrong JavaScript code:
<script>var returndata="{"text":"omrele"}";</script>

Here's the calling order:

1. app.config()
2. app.run()
3. directive's compile functions (if they are found in the dom)
4. app.controller()
5. directive's link functions (again, if found)

Here's a simple demo where you can watch each one executing (and experiment if you'd like).

From Angular's module docs:

Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.

Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.

One situation where run blocks are used is during authentications.

From the documentation:

In order to execute a command and have it not hang your PHP script while
it runs, the program you run must not output back to PHP. To do this,
redirect both stdout and stderr to /dev/null, then background it.

> /dev/null 2>&1 &

In order to execute a command and have
it spawned off as another process that
is not dependent on the Apache thread
to keep running (will not die if
somebody cancels the page) run this:

exec('bash -c "exec nohup setsid your_command > /dev/null 2>&1 &"');

I got this error when I tried to set a column as unique when there was already duplicate data in the column OR if you try to add a column and set it as unique when there is already data in the table.

I had a table with 5 rows and I tried to add a unique column and it failed because all 5 of those rows would be empty and thus not unique.

I created the column without the unique index set, then populated the data then set it as unique and everything worked.

The keys are not shuffled or renumbered. The unset() key is simply removed and the others remain.

$a = array(1,2,3,4,5);
unset($a[2]);
print_r($a);

Array
(
    [0] => 1
    [1] => 2
    [3] => 4
    [4] => 5
)

Setting export SSL_CERT_FILE=/path/file.crt should do the job.

your problem might not be related to any local or global scope for that matter just the server delay between the "success" function executing and the time you are trying to take out data from your variable.

chances are you are trying to print the contents of the variable before the ajax "success" function fires.

If you want one line:

list_of_dict = [{} for i in range(list_len)]

declare @interval tinyint
set @interval = 30
select dateadd(minute,(datediff(minute,0,[DateInsert])/@interval)*@interval,0), sum(Value_Transaction)
from Transactions
group by dateadd(minute,(datediff(minute,0,[DateInsert])/@interval)*@interval,0)

--ORACLE SQL EXAMPLE
SELECT
SYSDATE
,TO_DATE(SUBSTR(LAST_DAY(ADD_MONTHS(SYSDATE, -1)),1,10),'YYYY-MM-DD')
FROM DUAL

The legacy solution, before 1.6, was to use .attr and handle the returned value as a bool. The main problem is that the returned type of .attr has changed to string, and therefore the comparison with == true is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).

With 1.6 .prop was introduced, which returns a bool.

Nevertheless, I suggest to use .is(), as the returned type is intrinsically bool, like:

$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');

Furthermore .is() is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last'), .is(':visible'), ... please see documentation on selectors).

Another option is to use a ToggleButton with null background and a custom button.

Bellow an example that includes a selector to the text color as well.

<ToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:button="@drawable/toggle_selector"
    android:background="@null"
    android:paddingLeft="10dp"
    android:layout_centerHorizontal="true"
    android:gravity="center"
    android:textColor="@drawable/toggle_text"
    android:textOn="My on state"
    android:textOff="My off state" />

toggle_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:state_checked="true"
        android:drawable="@drawable/state_on" />

    <item
        android:drawable="@drawable/state_off" />

</selector>

toggle_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:state_checked="true"
        android:color="@color/app_color" />

    <item
        android:color="@android:color/darker_gray" />

</selector>

The need for pointers in C language is described here

The basic idea is that many limitations in the language (like using arrays, strings and modifying multiple variables in functions) could be removed by manipulating with the memory location of the data. To overcome these limitations, pointers were introduced in C.

Further, it is also seen that using pointers, you can run your code faster and save memory in cases where you are passing big data types (like a structure with many fields) to a function. Making a copy of such data types before passing would take time and would consume memory. This is another reason why programmers prefer pointers for big data types.

PS: Please refer the link provided for detailed explanation with sample code.

Regex for remove white space

\s+

var str = "Visit Microsoft!";
var res = str.replace(/\s+/g, "");
console.log(res);

or

[ ]+

var str = "Visit Microsoft!";
var res = str.replace(/[ ]+/g, "");
console.log(res);

Remove all white space at begin of string

^[ ]+

var str = "    Visit Microsoft!";
var res = str.replace(/^[ ]+/g, "");
console.log(res);

remove all white space at end of string

[ ]+$

var str = "Visit Microsoft!      ";
var res = str.replace(/[ ]+$/g, "");
console.log(res);

Without using any libraries:

std::string YourClass::Uppercase(const std::string & Text)
{
    std::string UppperCaseString;
    UppperCaseString.reserve(Text.size());
    for (std::string::const_iterator it=Text.begin(); it<Text.end(); ++it)
    {
        UppperCaseString.push_back(((0x60 < *it) && (*it < 0x7B)) ? (*it - static_cast<char>(0x20)) : *it);
    }
    return UppperCaseString;
}

I'd suggest following a few debugging steps.

First run the query directly against the DB. Confirm it is bringing results back. Even with something as simple as this you can find you've made a mistake, or the table is empty, or somesuch oddity.

If the above is ok, then try looping and echoing out the contents of $row just directly into the HTML to see what you've getting back in the mysql_query - see if it matches what you got directly in the DB.

If your data is output onto the page, then look at what's going wrong in your HTML formatting.

However, if nothing is output from $row, then figure out why the mysql_query isn't working e.g. does the user have permission to query that DB, do you have an open DB connection, can the webserver connect to the DB etc [something on these lines can often be a gotcha]

Changing your query slightly to

$sql = mysql_query("SELECT username FROM users") or die(mysql_error());  

may help to highlight any errors: php manual

I prefer going the long route. These are the checks I follow to avoid using a try-except clause -

1. check if variable is not None
2. then check if its a dataframe and
3. make sure its not empty

Here, DATA is the suspect variable -

DATA is not None and isinstance(DATA, pd.DataFrame) and not DATA.empty

intent.getAction().equals(SMS_RECEIVED)

I have tried it out successfully.

Well, by IP is faster.

Basically, when you call by server name, it is converted to original IP.

But it would be difficult to memorize an IP, for this reason the domain name was created.

Personally I use http://localhost instead of http://127.0.0.1 or http://username.

Here's some succinct Powershell code to apply new permissions to a folder by modifying it's existing ACL (Access Control List).

# Get the ACL for an existing folder
$existingAcl = Get-Acl -Path 'C:\DemoFolder'

# Set the permissions that you want to apply to the folder
$permissions = $env:username, 'Read,Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow'

# Create a new FileSystemAccessRule object
$rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permissions

# Modify the existing ACL to include the new rule
$existingAcl.SetAccessRule($rule)

# Apply the modified access rule to the folder
$existingAcl | Set-Acl -Path 'C:\DemoFolder'

Each of the values in the $permissions variable list pertain to the parameters of this constructor for the FileSystemAccessRule class.
