Encoding and decoding can solve this in Python 3:

Client Side:

>>> host='127.0.0.1'
>>> port=1337
>>> import socket
>>> s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
>>> s.connect((host,port))
>>> st='connection done'
>>> byt=st.encode()
>>> s.send(byt)
15
>>>

Server Side:

>>> host=''
>>> port=1337
>>> import socket
>>> s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
>>> s.bind((host,port))
>>> s.listen(1)
>>> conn ,addr=s.accept()
>>> data=conn.recv(2000)
>>> data.decode()
'connection done'
>>>

here is my soln to define the remote and local port and then write out to a file the received data, put this all in a class of your choice with the correct imports

    static UdpClient sendClient = new UdpClient();
    static int localPort = 49999;
    static int remotePort = 49000;
    static IPEndPoint localEP = new IPEndPoint(IPAddress.Any, localPort);
    static IPEndPoint remoteEP = new IPEndPoint(IPAddress.Parse("127.0.0.1"), remotePort);
    static string logPath = System.AppDomain.CurrentDomain.BaseDirectory + "/recvd.txt";
    static System.IO.StreamWriter fw = new System.IO.StreamWriter(logPath, true);


    private static void initStuff()
    {
      
        fw.AutoFlush = true;
        sendClient.ExclusiveAddressUse = false;
        sendClient.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
        sendClient.Client.Bind(localEP);
        sendClient.BeginReceive(DataReceived, sendClient);
    }

    private static void DataReceived(IAsyncResult ar)
    {
        UdpClient c = (UdpClient)ar.AsyncState;
        IPEndPoint receivedIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
        Byte[] receivedBytes = c.EndReceive(ar, ref receivedIpEndPoint);
        fw.WriteLine(DateTime.Now.ToString("HH:mm:ss.ff tt") +  " (" + receivedBytes.Length + " bytes)");

        c.BeginReceive(DataReceived, ar.AsyncState);
    }


    static void Main(string[] args)
    {
        initStuff();
        byte[] emptyByte = {};
        sendClient.Send(emptyByte, emptyByte.Length, remoteEP);
    }

I tried the code posted by larsmans above but, there are a couple of problems:

1) The code as is will throw the error as mentioned by mauguerra 2) If you change the code to the following:

...
    d1 = d1.strftime("%Y-%m-%d")
    d2 = d2.strftime("%Y-%m-%d")
    return abs((d2 - d1).days)

This will convert your datetime objects to strings but, two things

1) Trying to do d2 - d1 will fail as you cannot use the minus operator on strings and 2) If you read the first line of the above answer it stated, you want to use the - operator on two datetime objects but, you just converted them to strings

What I found is that you literally only need the following:

import datetime

end_date = datetime.datetime.utcnow()
start_date = end_date - datetime.timedelta(days=8)
difference_in_days = abs((end_date - start_date).days)

print difference_in_days

I would recommend using an actual anchor element, and set it as block.

<div class="divBox">
    <a href="#">Link</a>
</div>

.divBox
{
    width: 300px;
    height: 100px;
}
.divBox a
{
    width: 100%;
    height: 100%;
    display: block;
}

This will set the anchor to the same dimensions of the parent div.

You just have to refer your original list to be the one that the Collectors.toList() returns.

Here's a demo:

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class Reference {

  public static void main(String[] args) {
    List<Integer> list = Arrays.asList(1, 2, 3, 4, 5);
    System.out.println(list);

    // Just collect even numbers and start referring the new list as the original one.
    list = list.stream()
               .filter(n -> n % 2 == 0)
               .collect(Collectors.toList());
    System.out.println(list);
  }
}

And here's how you can add the newly created elements to your original list in just one line.

List<Integer> list = ...;
// add even numbers from the list to the list again.
list.addAll(list.stream()
                .filter(n -> n % 2 == 0)
                .collect(Collectors.toList())
);

That's what this Functional Programming Paradigm provides.

Use Enum.GetValues to retrieve an array of all values. Then select a random array item.

static Random _R = new Random ();
static T RandomEnumValue<T> ()
{
    var v = Enum.GetValues (typeof (T));
    return (T) v.GetValue (_R.Next(v.Length));
}

Test:

for (int i = 0; i < 10; i++) {
    var value = RandomEnumValue<System.DayOfWeek> ();
    Console.WriteLine (value.ToString ());
}

->

Tuesday
Saturday
Wednesday
Monday
Friday
Saturday
Saturday
Saturday

I believe you are using Bootstrap 3. If so, please try this code, here is the bootply

From the documentation:

It is necessary to keep in mind that the browsers do not know how to correctly show this error.

I suspect this is what's happening, if you inspect the HTTP to-and-fro using tools such as Firebug or Live HTTP Headers (both Firefox extensions) you'll be able to see what's really going on.

in my magento2 website ,show exactly the same error when click a product,

my solution is to go to edit the value of Search Engine Optimization - URL Key of this product,

make sure that there are only alphabet,number and - in URL Key, such as 100-washed-cotton-duvet-cover-set, deleting all other special characters ,such as % .

As @filoxo said, you can use document.querySelectorAll.

If you know that there is only one element with the class you are looking for, or you are interested only in the first one, you can use:

document.querySelector('.class1.class2');

BTW, while .class1.class2 indicates an element with both classes, .class1 .class2 (notice the whitespace) indicates an hierarchy - and element with class class2 which is inside en element with class class1:

<div class='class1'>
  <div>
    <div class='class2'>
      :
      :

And if you want to force retrieving a direct child, use > sign (.class1 > .class2):

<div class='class1'>
  <div class='class2'>
    :
    :

For entire information about selectors:

Here is a non jQuery solution that worked for me.

<div style="background:cyan; width:100px; height:100px;" onclick="if (event.srcElement==this) {console.log('outer');}">
    <a style="background:red" onclick="console.log('inner');">Click me</a>

Use this script: https://github.com/ricardobranco777/docker-volumes.sh

This does preserve data in volumes.

Example usage:

# Stop the container   
docker stop $CONTAINER

# Create a new image   
docker commit $CONTAINER $CONTAINER

# Save image
docker save -o $CONTAINER.tar $CONTAINER

# Save the volumes (use ".tar.gz" if you want compression)
docker-volumes.sh $CONTAINER save $CONTAINER-volumes.tar

# Copy image and volumes to another host
scp $CONTAINER.tar $CONTAINER-volumes.tar $USER@$HOST:

# On the other host:
docker load -i $CONTAINER.tar
docker create --name $CONTAINER [<PREVIOUS CONTAINER OPTIONS>] $CONTAINER

# Load the volumes
docker-volumes.sh $CONTAINER load $CONTAINER-volumes.tar

# Start container
docker start $CONTAINER

Use json_encode() if your server side scripting lang is PHP, json_encode() escapes the newline & other unexpected tokens for you (if not using PHP look for similar function for your scripting language)

then use $.parseJSON() in your JavaScript, done!

The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.

public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
    T returnObject = default(T);
    if (string.IsNullOrEmpty(XmlFilename)) return default(T);

    try
    {
        StreamReader xmlStream = new StreamReader(XmlFilename);
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        returnObject = (T)serializer.Deserialize(xmlStream);
    }
    catch (Exception ex)
    {
        ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
    }
    return returnObject;
}

Then you'd call it like this:

MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);

It's a lambda expression.

It means that, from the listOfCars, arg0 is one of the items of that list. With that item he is going to do, hence the ->, whatever is inside of the brackets.

In this example, he's going to return a list of cars that fit the condition

Car.SEDAN == ((Car)arg0).getStyle();

In C++11 you can. A note beforehand: Don't new the array, there's no need for that.

First, string[] strArray is a syntax error, that should either be string* strArray or string strArray[]. And I assume that it's just for the sake of the example that you don't pass any size parameter.

#include <string>

void foo(std::string* strArray, unsigned size){
  // do stuff...
}

template<class T>
using alias = T;

int main(){
  foo(alias<std::string[]>{"hi", "there"}, 2);
}

Note that it would be better if you didn't need to pass the array size as an extra parameter, and thankfully there is a way: Templates!

template<unsigned N>
void foo(int const (&arr)[N]){
  // ...
}

Note that this will only match stack arrays, like int x[5] = .... Or temporary ones, created by the use of alias above.

int main(){
  foo(alias<int[]>{1, 2, 3});
}

The best way for me was using vector with categories in order I need as limits parameter to scale_x_discrete. I think it is pretty simple and straightforward solution.

ggplot(mtcars, aes(factor(cyl))) + 
  geom_bar() + 
  scale_x_discrete(limits=c(8,4,6))

Last time I had a look at this, (and admittedly it was a while back) the biggest difference I noticed was in the garbage collection.

IIRC:

• The server heap VM has a differnt number of generations than the Client VM, and a different garbage collection algorithm. This may not be true anymore
• The server VM will allocate memory and not release it to the OS
• The server VM will use more sophisticated optimisation algorithms, and hence have bigger time and memory requirements for optimisation

If you can compare two java VMs, one client, one server using the jvisualvm tool, you should see a difference in the frequency and effect of the garbage collection, as well as in the number of generations.

I had a pair of screenshots that showed the difference really well, but I can't reproduce as I have a 64 bit JVM which only implements the server VM. (And I can't be bothered to download and wrangle the 32 bit version on my system as well.)

This doesn't seem to be the case anymore, having tried running some code on windows with both server and client VMs, I seem to get the same generation model for both...

LD_LIBRARY_PATH is the default library path which is accessed to check for available dynamic and shared libraries. It is specific to linux distributions.

It is similar to environment variable PATH in windows that linker checks for possible implementations during linking time.

import psutil

for p in psutil.process_iter(attrs=['pid', 'name']):
    if "itunes.exe" in (p.info['name']).lower():
        print("yes", (p.info['name']).lower())

for python 3.7

import psutil

for p in psutil.process_iter(attrs=['pid', 'name']):
    if p.info['name'] == "itunes.exe":
        print("yes", (p.info['name']))

This works for python 3.8 & psutil 5.7.0, windows

Other solutions mix regex syntaxes. To use perl/PCRE patterns for both search and replace, and only process matching files, this works quite well:

grep -rlIZPi 'match1' | xargs -0r perl -pi -e 's/match2/replace/gi;'

match1 and match2 are usually identical but match1 can be simplified to remove more advanced features that are only relevant to the substitution, e.g. capturing groups.

Translation: grep recursively and list matching filenames, each separated by nul to protect any special characters; pipe any filenames to xargs which is expecting a nul-separated list; if any filenames are received, pass them to perl to perform the actual substitutions.

For case-sensitive matching, drop the i flag from grep and the i pattern modifier from the s/// expression, but not the i flag from perl itself. Remove the I flag from grep to include binary files.

The padding inside a table-divider (TD) is a padding property applied to the cell itself.

CSS

td, th {padding:0}

The spacing in-between the table-dividers is a space between cell borders of the TABLE. To make it effective, you have to specify if your table cells borders will 'collapse' or be 'separated'.

CSS

table, td, th {border-collapse:separate}
table {border-spacing:6px}

    public get totalSeconds(): number {
        return this._millis / MILLIS_PER_SECOND;
    }

    public get totalMilliseconds(): number {
        return this._millis;
    }

    public add(ts: TimeSpan): TimeSpan {
        const result = this._millis + ts.totalMilliseconds;
        return new TimeSpan(result);
    }

    public subtract(ts: TimeSpan): TimeSpan {
        const result = this._millis - ts.totalMilliseconds;
        return new TimeSpan(result);
    }
}

How to use

Create a new TimeSpan object

    const ts = TimeSpan.zero;

    const milliseconds = 10000; // 1 second

    // by using the constructor
    const ts1 = new TimeSpan(milliseconds);

    // or as an alternative you can use the static factory method
    const ts2 = TimeSpan.fromMilliseconds(milliseconds);

    const seconds = 86400; // 1 day
    const ts = TimeSpan.fromSeconds(seconds);

    const minutes = 1440; // 1 day
    const ts = TimeSpan.fromMinutes(minutes);

    const hours = 24; // 1 day
    const ts = TimeSpan.fromHours(hours);

    const days = 1; // 1 day
    const ts = TimeSpan.fromDays(days);

    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const ts = TimeSpan.fromTime(hours, minutes, seconds);

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime(days, hours, minutes, seconds, milliseconds);

    const ts = TimeSpan.maxValue;

    const ts = TimeSpan.minValue;

    const ts = TimeSpan.minValue;

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.add(ts2);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.subtract(ts2);

    console.log(ts.days);               // 0
    console.log(ts.hours);              // 23
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime2(days, hours, minutes, seconds, milliseconds);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 1
    console.log(ts.seconds);            // 1
    console.log(ts.milliseconds);           // 1

    console.log(ts.totalDays)           // 1.0423726967592593;
    console.log(ts.totalHours)          // 25.016944722222224;
    console.log(ts.totalMinutes)            // 1501.0166833333333;
    console.log(ts.totalSeconds)            // 90061.001;
    console.log(ts.totalMilliseconds);      // 90061001;

DEMO.

If you use custom Makefiles, you can double click on the .includes file and add it there.

you can do this:

<div class="picture1">&nbsp;</div>

and put this into your css file:

div.picture1 {
   width:100px; /*width of your image*/
   height:100px; /*height of your image*/
   background-image:url('yourimage.file');
   margin:0; /* If you want no margin */
   padding:0; /*if your want to padding */
}

otherwise, just use them as plain

You need to run your script after the element exists. Move the <input type="hidden" name="checkyear" id="checkyear" value=""> to the beginning.

Since div's by default are block elements - meaning they will occupy full available width, try using -

display:inline-block;

The div is now rendered inline i.e. does not disrupt flow of elements, but will still be treated as a block element.

I find this technique easier than wrestling with floats.

See this tutorial for more - http://learnlayout.com/inline-block.html. I would recommend even the previous articles that lead up to that one. (No, I did not write it)

I'm not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

This also works in Silverlight 5 (perhaps earlier as well but i haven't tested it). I used the relative source like this and it worked fine.

RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=telerik:RadGridView}"

In my situation it was related to Web Site/Web Application type of the project. We recently moved to MVC and had to change it to Web Application.

So, the solution was simple: select your web-site in Solution Explorer and remove it from the solution, then right click on the solution and select Add -> Existing Project (not Web Site), recompile the web-site.

The way I do is go to http://getbootstrap.com/customize/ and only check "grid system" to download. There are bootstrap-theme.css and bootstrap.css in downloaded files, and I only need the latter.

In this way, I can use the grid system of Bootstrap, with everything else from Material UI.

Nice shorthand for Multiple variable assignments

{% set label_cls, field_cls = "col-md-7", "col-md-3" %}

Finally, I got the mistake and the reason was I need to stringify the JSON data I was sending. I have to set the content type and datatype in XHR object. So the correct version is here:

$.ajax({
  type: 'POST',
  url: "http://localhost:8080/project/server/rest/subjects",
  data: JSON.stringify({
    "subject:title":"Test Name",
    "subject:description":"Creating test subject to check POST method API",
    "sub:tags": ["facebook:work", "facebook:likes"],
    "sampleSize" : 10,
    "values": ["science", "machine-learning"]
  }),
  error: function(e) {
    console.log(e);
  },
  dataType: "json",
  contentType: "application/json"
});

May be it will help someone else.

Here is the codepen demo showing the solution:

• Demo - Fill remaining vertical space with CSS using display:flex

Important highlights:

• all containers from html, body, ... .container, should have the height set to 100%
• introducing flex to ANY of the flex items will trigger calculation of the items sizes based on flex distribution:
  • if only one cell is set to flex, for example: flex: 1 then this flex item will occupy the remaining of the space
  • if there are more than one with the flex property, the calculation will be more complicated. For example, if the item 1 is set to flex: 1 and the item 2 is se to flex: 2 then the item 2 will take twice more of the remaining space
    • NOT TRUE: the item 2 will be twice larger than the item 1
    • check more about the concept of the remaining space: https://developer.mozilla.org/en-US/docs/Web/CSS/flex-grow
• Main Size Property
  • depends on the value of the flex-direction property
  • in our case height is just a preferred size
  • it will be overwritten in the presence of flex property: https://www.w3.org/TR/css-flexbox-1/#propdef-flex
    • When a box is a flex item, flex is consulted instead of the main size property to determine the main size of the box
  • min-* and max-* will be respected

All the parameters after ? can be accessed using $_GET array. So,

echo $_GET['email'];

will extract the emails from urls.

Like Rubanov wrote for C#, i write it for Java, and it is:

    public void waitForPageLoaded() {
    ExpectedCondition<Boolean> expectation = new
            ExpectedCondition<Boolean>() {
                public Boolean apply(WebDriver driver) {
                    return (((JavascriptExecutor) driver).executeScript("return document.readyState").toString().equals("complete")&&((Boolean)((JavascriptExecutor)driver).executeScript("return jQuery.active == 0")));
                }
            };
    try {
        Thread.sleep(100);
        WebDriverWait waitForLoad = new WebDriverWait(driver, 30);
        waitForLoad.until(expectation);
    } catch (Throwable error) {
        Assert.fail("Timeout waiting for Page Load Request to complete.");
    }
}

KEEPING THE DIRECTORY NAME

The subdirectory-filter (or the shorter command git subtree) works good but did not work for me since they remove the directory name from the commit info. In my scenario I just want to merge parts of one repository into another and retain the history WITH full path name.

My solution was to use the tree-filter and to simply remove the unwanted files and directories from a temporary clone of the source repository, then pull from that clone into my target repository in 5 simple steps.

# 1. clone the source
git clone ssh://<user>@<source-repo url>
cd <source-repo>
# 2. remove the stuff we want to exclude
git filter-branch --tree-filter "rm -rf <files to exclude>" --prune-empty HEAD
# 3. move to target repo and create a merge branch (for safety)
cd <path to target-repo>
git checkout -b <merge branch>
# 4. Add the source-repo as remote 
git remote add source-repo <path to source-repo>
# 5. fetch it
git pull source-repo master
# 6. check that you got it right (better safe than sorry, right?)
gitk

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

First, it depends on your version of R. If you've passed 2.11, you can use aggreggate with multiple results functions(summary, by instance, or your own function). If not, you can use the answer made by Justin.

There're two kind of Django "projects" that I have in my ~/projects/ directory, both have a bit different structure.:

• Stand-alone websites
• Pluggable applications

Stand-alone website

Mostly private projects, but doesn't have to be. It usually looks like this:

~/projects/project_name/

docs/               # documentation
scripts/
  manage.py         # installed to PATH via setup.py
project_name/       # project dir (the one which django-admin.py creates)
  apps/             # project-specific applications
    accounts/       # most frequent app, with custom user model
    __init__.py
    ...
  settings/         # settings for different environments, see below
    __init__.py
    production.py
    development.py
    ...
        
  __init__.py       # contains project version
  urls.py
  wsgi.py
static/             # site-specific static files
templates/          # site-specific templates
tests/              # site-specific tests (mostly in-browser ones)
tmp/                # excluded from git
setup.py
requirements.txt
requirements_dev.txt
pytest.ini
...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

setup.py

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn't care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It's really just a matter of taste.

The same applies for locale, although sometimes it's convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It's used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I've created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate
export DJANGO_SETTINGS_MODULE=project_name.settings.production
git pull
pip install -r requirements.txt

# Update database, static files, locales
manage.py syncdb  --noinput
manage.py migrate
manage.py collectstatic --noinput
manage.py makemessages -a
manage.py compilemessages

# restart wsgi
touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I've used it for one project only and I'm still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven't used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I've taken example below from django-forme

~/projects/django-app/

docs/
app/
tests/
example_project/
LICENCE
MANIFEST.in
README.md
setup.py
pytest.ini
tox.ini
.travis.yml
...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn't matter. It is important to provide README and setup.py, so package is easily installed through pip.

Use Pre-request script tab to write javascript to get and save the date into a variable:

const dateNow= new Date();
pm.environment.set('currentDate', dateNow.toISOString());

and then use it in the request body as follows:

"currentDate": "{{currentDate}}"

OR

.section:hover > div {
  background-color: #0CF;
}

NOTE Parent element state can only affect a child's element state so you can use:

.image:hover + .layer {
  background-color: #0CF;
}
.image:hover {
  background-color: #0CF;
}

but you can not use

.layer:hover + .image {
  background-color: #0CF;
}

Keep in mind the actual fragmentation that occurs when DELETE+INSERT is issued opposed to a correctly implemented UPDATE will make great difference by time.

Thats why, for instance, REPLACE INTO that MySQL implements is discouraged as opposed to using the INSERT INTO ... ON DUPLICATE KEY UPDATE ... syntax.

You may want to try using the inttypes.h library that gives you types such as int32_t, int64_t, uint64_t etc. You can then use its macros such as:

uint64_t x;
uint32_t y;

printf("x: %"PRId64", y: %"PRId32"\n", x, y);

This is "guaranteed" to not give you the same trouble as long, unsigned long long etc, since you don't have to guess how many bits are in each data type.

Try this

if($("input:radio[name=postage]").is(":checked")){
  //Code to append goes here
}

I will just repeat what @Ivo Bosticky said which can be overlooked. Put these lines at the VERY start of the py file.

import matplotlib
matplotlib.use('Agg') 

Or one would get error

*/usr/lib/pymodules/python2.7/matplotlib/__init__.py:923: UserWarning:  This call to   matplotlib.use() has no effect
because the the backend has already been chosen;
matplotlib.use() must be called *before* pylab, matplotlib.pyplot,*

This will resolve all Display issue

I have a perfect solution for this problem. After doing following simple steps you will be able to Import your source codes in Eclipse!

First of all, the reason why you can not Import your project into Eclipse workstation is that you do not have .project and .classpath file.

Now we know why this happens, so all we need to do is to create .project and .classpath file inside the project file. Here is how you do it:

First create .classpath file:

1. create a new txt file and name it as .classpath

2. copy paste following codes and save it:

   <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> </classpath>

Then create .project file:

1. create a new txt file and name it as .project

2. copy paste following codes:

   <?xml version="1.0" encoding="UTF-8"?> <projectDescription> <name>HereIsTheProjectName</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>org.eclipse.jdt.core.javanature</nature> </natures> </projectDescription>

3. you have to change the name field to your project name. you can do this in line 3 by changing HereIsTheProjectName to your own project name. then save it.

That is all, Enjoy!!

I had using solution all this way in this thread, and it's easy working with plugin Android Drawable Importer

If u using Android Studio on MacOS, just try this step to get in:

• Click bar menu Android Studio then choose Preferences or tap button Command + ,
• Then choose Plugins
• Click Browse repositories
• Write in the search coloumn Android Drawable Importer
• Click Install button
• And then dialog Restart is showing, just restart it Android Studio

After ur success installing the plugin, to work it this plugin just click create New menu and then choose Batch Drawable Import. Then click plus button a.k.a Add button, and go choose your file to make drawable. And then just click ok and ok the drawable has make it all of them.

If u confused with my word, just see the image tutorial from learningmechine.

In TestNG, you use dependsOnMethods and/or dependsOnGroups:

@Test(groups = "a")
public void f1() {}

@Test(groups = "a")
public void f2() {}

@Test(dependsOnGroups = "a")
public void g() {}

In this case, g() will only run after f1() and f2() have completed and succeeded.

You will find a lot of examples in the documentation: http://testng.org/doc/documentation-main.html#test-groups

Thanks it working

here i am done with this by qty field is zero means it shown that cells are in red color

        int count = 0;

        foreach (DataGridViewRow row in ItemDg.Rows)
        {
            int qtyEntered = Convert.ToInt16(row.Cells[1].Value);
            if (qtyEntered <= 0)
            {
                ItemDg[0, count].Style.BackColor = Color.Red;//to color the row
                ItemDg[1, count].Style.BackColor = Color.Red;

                ItemDg[0, count].ReadOnly = true;//qty should not be enter for 0 inventory                       
            }
            ItemDg[0, count].Value = "0";//assign a default value to quantity enter
            count++;
        }

    }

Everyone else's method doesn't account for whitespaces. Obviously nobody really considers a whitespace a special character.

Use this method to detect special characters not including whitespaces:

import re

def detect_special_characer(pass_string): 
  regex= re.compile('[@_!#$%^&*()<>?/\|}{~:]') 
  if(regex.search(pass_string) == None): 
    res = False
  else: 
    res = True
  return(res)

If you want to create anonymous array with some values so you can use this syntax.

var arr = new Array(50).fill().map((d,i)=>++i)
console.log(arr)

You can also check run time. Put one breakpoint in code and inside (lldb) console write

(lldb) po [yourObject class]

Like this..

its awful oracle installer:

[INS-13001]

I got it as I used MY_PC as NETBIOS name instead of MYPC (Underscore is bad for it..)

Can be an historical reason.. but message is obscure.

This is simple program showing append('t') to the list.
n=['f','g','h','i','k']

for i in range(1):
    temp=[]
    temp.append(n[-2:])
    temp.append('t')
    print(temp)

Output: [['i', 'k'], 't']

Using a regular expression to remove text which could cause a SQL injection sounds like the SQL statement is being sent to the database via a Statement rather than a PreparedStatement.

One of the easiest ways to prevent an SQL injection in the first place is to use a PreparedStatement, which accepts data to substitute into a SQL statement using placeholders, which does not rely on string concatenations to create an SQL statement to send to the database.

For more information, Using Prepared Statements from The Java Tutorials would be a good place to start.

Both these work for me. Maybe post a complete example?

With Spark 2.4+, if you want to load a csv from a local directory, then you can use 2 sessions and load that into hive. The first session should be created with master() config as "local[*]" and the second session with "yarn" and Hive enabled.

The below one worked for me.

import org.apache.log4j.{Level, Logger}
import org.apache.spark._
import org.apache.spark.rdd._
import org.apache.spark.sql._

object testCSV { 

  def main(args: Array[String]) {
    Logger.getLogger("org").setLevel(Level.ERROR)
    val spark_local = SparkSession.builder().appName("CSV local files reader").master("local[*]").getOrCreate()

    import spark_local.implicits._
    spark_local.sql("SET").show(100,false)
    val local_path="/tmp/data/spend_diversity.csv"  // Local file
    val df_local = spark_local.read.format("csv").option("inferSchema","true").load("file://"+local_path) // "file://" is mandatory
    df_local.show(false)

    val spark = SparkSession.builder().appName("CSV HDFS").config("spark.sql.warehouse.dir", "/apps/hive/warehouse").enableHiveSupport().getOrCreate()

    import spark.implicits._
    spark.sql("SET").show(100,false)
    val df = df_local
    df.createOrReplaceTempView("lcsv")
    spark.sql(" drop table if exists work.local_csv ")
    spark.sql(" create table work.local_csv as select * from lcsv ")

   }

When ran with spark2-submit --master "yarn" --conf spark.ui.enabled=false testCSV.jar it went fine and created the table in hive.

OK, first of all I'm not sure how it works when you create a div using (document.createElement('div')), so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?

If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?

Here's the code for my example:

HTML

<a href="#new">Click</a> 
<div id="new">
    Fade in ... 
</div>

CSS

#new {
    width: 100px;
    height: 100px;
    border: 1px solid #000000;
    opacity: 0;    
}


#new:target {
    -webkit-transition: opacity 2.0s ease-in;
       -moz-transition: opacity 2.0s ease-in;
         -o-transition: opacity 2.0s ease-in;
                                  opacity: 1;
}

... and here's a jsFiddle

Here is my solution for those who use hook; If you are listing items in your grid and want to remove the selected item, you can use this solution.

var list = data.filter(form => form.id !== selectedRowDataId);
setData(list);

Brief

conda is both a command line tool, and a python package.

Miniconda installer = Python + conda

Anaconda installer = Python + conda + meta package anaconda

meta Python pkg anaconda = about 160 Python pkgs for daily use in data science

Anaconda installer = Miniconda installer + conda install anaconda

Detail

1. conda is a python manager and an environment manager, which makes it possible to

   • install package with conda install flake8
   • create an environment with any version of Python with conda create -n myenv python=3.6

2. Miniconda installer = Python + conda

   conda, the package manager and environment manager, is a Python package. So Python is installed. Cause conda distribute Python interpreter with its own libraries/dependencies but not the existing ones on your operating system, other minimal dependencies like openssl, ncurses, sqlite, etc are installed as well.

   Basically, Miniconda is just conda and its minimal dependencies. And the environment where conda is installed is the "base" environment, which is previously called "root" environment.

3. Anaconda installer = Python + conda + meta package anaconda

4. meta Python package anaconda = about 160 Python pkgs for daily use in data science

   Meta packages, are packages that do NOT contain actual softwares and simply depend on other packages to be installed.

   Download an anaconda meta package from Anaconda Cloud and extract the content from it. The actual 160+ packages to be installed are listed in info/recipe/meta.yaml.

   The pre-installed packages from meta pkg anaconda are mainly for web scraping and data science. Like requests, beautifulsoup, numpy, nltk, etc.

   If you have a Miniconda installed, conda install anaconda will make it same as an Anaconda installation, except that the installation folder names are different.

5. Miniconda2 v.s. Miniconda. Anaconda2 v.s. Anaconda.

   2 means the bundled Python interpreter for conda in the "base" environment is Python 2, but not Python 3.

Another way of doing this in plain bash is making use of the rev command like this:

cat file | rev | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Basically, you reverse the lines of the file, then split them with cut using space as the delimiter, take the first field that cut produces and then you reverse the token again, use tr -d to delete unwanted chars and tr again to replace newline chars with ,

Also, you can avoid the first cat by doing:

rev < file | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Here is a link please use this to make the div in the center if position is absolute.

HTML:

<div class="bar"></div>

CSS:

.bar{
  width:200px;
  border-top:4px solid red;
  position:absolute;
  margin-left:auto;
  margin-right:auto;
  left:0;
  right:0;
}

Example jsfiddle

In Xcode 7 - 13,

when you change storyboard IDs and you get errors like this,

just CLEAN your project (CMD+SHIFT+K)

All the other answers are correct, however, you might have problems if you're trying to check directory in a user's home directory. Make sure you expand the relative path before checking:

File.exists? '~/exists'
=> false
File.directory? '~/exists'
=> false
File.exists? File.expand_path('~/exists')
=> true

I had the same problem and I found out that if you add the URL param ?v=3 you won't get the warning message anymore:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>

Reproduction online

As pointed out in the comments by @Zia Ul Rehman Mughal

Turns out specifying this means you are referring to old frozen version 3.0 not the latest version. Frozen old versions are not updated with bug fixes or anything. But this is good to mention though. https://developers.google.com/maps/documentation/javascript/versions#the-frozen-version

Update 07-Jun-2016

This solution doesn't work anymore.

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Use Ajax to send request to the PHP script ,check that required field are not empty or incorrect using js also keep a record of mail send by whom from your server.

function sendMail() is good for doing that.

Check for any error caught while mailing from your script and take appropriate action.
For resolving it for example if the mail address is incorrect or mail is not send due to server problem or it's in queue in such condition report it to user immediately and prevent multi sending same email again and again. Get response from your script Using jQuery GET and POST

$.get(URL,callback); $.post(URL,callback);

I ran into this problem today and wanted to share my solution. In my case, the solution was to delete the Child items before getting the Parent from the database.

Previously I was doing it like in the code below. I will then get the same error listed in this question.

var Parent = GetParent(parentId);
var children = Parent.Children;
foreach (var c in children )
{
     Context.Children.Remove(c);
}
Context.SaveChanges();

What worked for me, is to get the children items first, using the parentId (foreign key) and then delete those items. Then I can get the Parent from the database and at that point, it should not have any children items anymore and I can add new children items.

var children = GetChildren(parentId);
foreach (var c in children )
{
     Context.Children.Remove(c);
}
Context.SaveChanges();

var Parent = GetParent(parentId);
Parent.Children = //assign new entities/items here

It is common to use the MAC address is associated with the network card.

The address is available in Java 6 through through the following API:

Java 6 Docs for Hardware Address

I haven't used it in Java, but for other network identification applications it has been helpful.

I tried to give a simple explanation in my blogpost.

UTF-32

requires 32 bits (4 bytes) to encode any character. For example, in order to represent the "A" character code-point using this scheme, you'll need to write 65 in 32-bit binary number:

00000000 00000000 00000000 01000001 (Big Endian)

If you take a closer look, you'll note that the most-right seven bits are actually the same bits when using the ASCII scheme. But since UTF-32 is fixed width scheme, we must attach three additional bytes. Meaning that if we have two files that only contain the "A" character, one is ASCII-encoded and the other is UTF-32 encoded, their size will be 1 byte and 4 bytes correspondingly.

UTF-16

Many people think that as UTF-32 uses fixed width 32 bit to represent a code-point, UTF-16 is fixed width 16 bits. WRONG!

In UTF-16 the code point maybe represented either in 16 bits, OR 32 bits. So this scheme is variable length encoding system. What is the advantage over the UTF-32? At least for ASCII, the size of files won't be 4 times the original (but still twice), so we're still not ASCII backward compatible.

Since 7-bits are enough to represent the "A" character, we can now use 2 bytes instead of 4 like the UTF-32. It'll look like:

00000000 01000001

UTF-8

You guessed right.. In UTF-8 the code point maybe represented using either 32, 16, 24 or 8 bits, and as the UTF-16 system, this one is also variable length encoding system.

Finally we can represent "A" in the same way we represent it using ASCII encoding system:

01001101

A small example where UTF-16 is actually better than UTF-8:

Consider the Chinese letter "?" - its UTF-8 encoding is:

11101000 10101010 10011110

While its UTF-16 encoding is shorter:

10001010 10011110

In order to understand the representation and how it's interpreted, visit the original post.

If you don't mind leaving pure C# and going for WinApi calls, then you might want to consider the PathIsDirectoryEmpty() function. According to the MSDN, the function:

Returns TRUE if pszPath is an empty directory. Returns FALSE if pszPath is not a directory, or if it contains at least one file other than "." or "..".

That seems to be a function which does exactly what you want, so it is probably well optimised for that task (although I haven't tested that).

To call it from C#, the pinvoke.net site should help you. (Unfortunately, it doesn't describe this certain function yet, but you should be able to find some functions with similar arguments and return type there and use them as the basis for your call. If you look again into the MSDN, it says that the DLL to import from is shlwapi.dll)

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

First of all, input element shouldn't have a closing tag (from http://www.w3.org/TR/html401/interact/forms.html#edef-INPUT : End tag: forbidden ).

Second thing, you need the after(), not append() function.

I was tinkering around when moving our applications to HTML5 with RESTful apis in the backend. The solution that I came up with was:

1. Client is issued with a token with a session time of 30 mins (or whatever the usual server side session time) upon successful login.
2. A client-side timer is created to call a service to renew the token before its expiring time. The new token will replace the existing in future calls.

As you can see, this reduces the frequent refresh token requests. If user closes the browser/app before the renew token call is triggered, the previous token will expire in time and user will have to re-login.

A more complicated strategy can be implemented to cater for user inactivity (e.g. neglected an opened browser tab). In that case, the renew token call should include the expected expiring time which should not exceed the defined session time. The application will have to keep track of the last user interaction accordingly.

I don't like the idea of setting long expiration hence this approach may not work well with native applications requiring less frequent authentication.

You need to specify the source dir

File> Project Structure > Modules

click the directory and click the Sources button

It's weird because usually it's done automatically. Maybe it's better if you recreate the project again.

The OP's solution is nearly there, there are just a few things to make it more Pythonic.

For one, there's no need to get the length of the list. Empty lists in Python evaluate to False in an if check. Just simply say

if list:

Additionally, it's a very Bad Idea to assign to variables that overlap with reserved words. "list" is a reserved word in Python.

So let's change that to

some_list = get_list()
if some_list:

A really important point that a lot of solutions here miss is that all Python functions/methods return None by default. Try the following below.

def does_nothing():
    pass

foo = does_nothing()
print foo

Unless you need to return None to terminate a function early, it's unnecessary to explicitly return None. Quite succinctly, just return the first entry, should it exist.

some_list = get_list()
if some_list:
    return list[0]

And finally, perhaps this was implied, but just to be explicit (because explicit is better than implicit), you should not have your function get the list from another function; just pass it in as a parameter. So, the final result would be

def get_first_item(some_list): 
    if some_list:
        return list[0]

my_list = get_list()
first_item = get_first_item(my_list)

As I said, the OP was nearly there, and just a few touches give it the Python flavor you're looking for.

If you're using display:table-row etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:

<tr style="width:100%">
    <td>Type</td>
    <td style="float:right">Name</td>
</tr>

Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table, thead, tbody, etc.)

Instead, add an outer element with display:table, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats with table elements. It'll cause so many headaches.

markup:

<div class="view-table">
    <div class="view-row">
        <div class="view-type">Type</div>
        <div class="view-name">Name</div>                
    </div>
</div>

CSS:

.view-table
{
    display:table;
    width:100%;
}
.view-row,
{
    display:table-row;
}
.view-row > div
{
    display: table-cell;
}
.view-name 
{
    text-align:right;
}

By pid:

pgrep [pid] >/dev/null

By name:

pgrep -u [user] -x [name] >/dev/null

"-x" means "exact match".

I have nothing against gotos in general, but I can think of several reasons why you wouldn't want to use them for a loop like you mentioned:

• It does not limit scope hence any temp variables you use inside won't be freed until later.
• It does not limit scope hence it could lead to bugs.
• It does not limit scope hence you cannot re-use the same variable names later in future code in the same scope.
• It does not limit scope hence you have the chance of skipping over a variable declaration.
• People are not accustomed to it and it will make your code harder to read.
• Nested loops of this type can lead to spaghetti code, normals loops will not lead to spaghetti code.

window load will wait for all resources to be loaded.

document ready waits for the document to be initialized.

unload well, waits till the document is being unloaded.

the order is: document ready, window load, ... ... ... ... window unload.

always use document ready unless you need to wait for your images to load.

shorthand for document ready:

$(function(){
    // yay!
});

Try using ,

$('#points').val(request.responseText);

Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons

• Add the package to your pubspec.yaml file (within your Flutter project) to use it
• Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.
• Run the package
• Voila! The default launcher icons have now been replaced with your custom icon

I'm hoping to add a video to the GitHub README to demonstrate it

Video showing how to run the tool can be found here.

If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.

Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.

Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.

Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project

The _id field is always present unless you explicitly exclude it. Do so using the - syntax:

exports.someValue = function(req, res, next) {
    //query with mongoose
    var query = dbSchemas.SomeValue.find({}).select('name -_id');

    query.exec(function (err, someValue) {
        if (err) return next(err);
        res.send(someValue);
    });
};

Or explicitly via an object:

exports.someValue = function(req, res, next) {
    //query with mongoose
    var query = dbSchemas.SomeValue.find({}).select({ "name": 1, "_id": 0});

    query.exec(function (err, someValue) {
        if (err) return next(err);
        res.send(someValue);
    });
};

Try this.

// Directory
$directory = "/dir";

// Returns array of files
$files = scandir($directory);

// Count number of files and store them to variable..
$num_files = count($files)-2;

Not counting the '.' and '..'.

There are two ways :

1. using .htaccess : Options -Indexes

2. create blank index.html

When you call the wait() of the "object"(expecting the object lock is acquired),intern this will release the lock on that object and help's the other threads to have lock on this "object", in this scenario there will be more than 1 thread waiting for the "resource/object"(considering the other threads also issued the wait on the same above object and down the way there will be a thread that fill the resource/object and invokes notify/notifyAll).

Here when you issue the notify of the same object(from the same/other side of the process/code),this will release a blocked and waiting single thread (not all the waiting threads -- this released thread will be picked by JVM Thread Scheduler and all the lock obtaining process on the object is same as regular).

If you have Only one thread that will be sharing/working on this object , it is ok to use the notify() method alone in your wait-notify implementation.

if you are in situation where more than one thread read's and writes on resources/object based on your business logic,then you should go for notifyAll()

now i am looking how exactly the jvm is identifying and breaking the waiting thread when we issue notify() on a object ...

Some browsers repeat the thead element on each page, as they are supposed to. Others need some help: Add this to your CSS:

thead {display: table-header-group;}
tfoot {display: table-header-group;}

Opera 7.5 and IE 5 won't repeat headers no matter what you try.

Somebody asked me to post a link to the framework! that I presented at Open World 2012. This is the full blog post that demonstrates how to architect a solution with external tables.

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm("Index", "Company", FormMethod.Get))
{
    <p>
        Find by Name: @Html.TextBox("SearchString", ViewBag.CurrentFilter as string)
        <input type="submit" value="Search" />
        <input type="button" value="Clear" onclick="location.href='@Url.Action("Index","Company")'"/>
    </p>
}

In the above example you can see that If I specifically need a button to do some action, I have to do it with @Url.Action whereas if I just want a link I will use @Html.ActionLink. The point is when you have to use some element(HTML) with action url is used.

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

if you state a.redLink{color:red;} then to keep this on hover and such add a.redLink:hover{color:red;} This will make sure no other hover states will change the color of your links

The model (@Model) only exists while the page is being constructed. Once the page is rendered in the browser, all that exists is HTML, JavaScript and CSS.

What you will want to do is put the PostID in a hidden field. As the PostID value is fixed, there actually is no need for JavaScript. A simple @HtmlHiddenFor will suffice.

However, you will want to change your foreach loop to a for loop. The final solution will look something like this:

for (int i = 0 ; i < Model.Post; i++)
{
    <br/>
    <b>Posted by :</b> @Model.Post[i].Username <br/>
    <span>@Model.Post[i].Content</span> <br/>
    if(Model.loginuser == Model.username)
    {
        @Html.HiddenFor(model => model.Post[i].PostID)
        @Html.TextAreaFor(model => model.addcomment.Content)
        <button type="submit">Add Comment</button>
    }
}

Most easiest plugin for pagination.

https://www.npmjs.com/package/mongoose-paginate-v2

Add plugin to a schema and then use model paginate method:

var mongoose         = require('mongoose');
var mongoosePaginate = require('mongoose-paginate-v2');

var mySchema = new mongoose.Schema({ 
    /* your schema definition */ 
});

mySchema.plugin(mongoosePaginate);

var myModel = mongoose.model('SampleModel',  mySchema); 

myModel.paginate().then({}) // Usage

In my case, the reason was the following:

• my injectable service A extended another class B
• B had a constructor which required an argument
• I hadn't defined any constructor in A

As a consequence, when trying to create an object A, the default constructor failed. I have no idea why this wasn't a compile error.

I got it fixed by simply adding a constructor in A, which correctly called B's constructor.

<a href="{{ url()->previous() }}" class="btn btn-warning"><i class="fa fa-angle-left"></i> Continue Shopping</a>

This worked in Laravel 5.8

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

While there is a maven command you can execute to do this, it's easier to just delete the files manually from the repository.

Like this on windows Documents and Settings\your username\.m2 or $HOME/.m2 on Linux

Or if you like to mix outputs (stdout & stderr) in one single file you may want to use:

command > merged-output.txt 2>&1

A PowerShell script based on @Mithrl's answer

# export_env.ps1
$Date = Get-Date
$DateStr = '{0:dd-MM-yyyy}' -f $Date

mkdir -Force $PWD\env_exports | Out-Null

regedit /e "$PWD\env_exports\user_env_variables[$DateStr].reg" "HKEY_CURRENT_USER\Environment"
regedit /e "$PWD\env_exports\global_env_variables[$DateStr].reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

For SQL Server 2012, or later, an easier solution is to use FORMAT ()^{Documentation}.
EG:

SELECT Format(1234567.8, '##,##0') 

Results in: 1,234,568

pycron is close match on Windows. The following entries are supported:

1    Minute (0-59)
2    Hour (2-24)
3    Day of month (1-31)
4    Month (1-12, Jan, Feb, etc)
5    Day of week (0-6) 0 = Sunday, 1 = Monday etc or Sun, Mon, etc)
6    User that the command will run as
7    Command to execute

These issue arise generally due to mismatch between @ngx-translate/core version and Angular .Before installing check compatible version of corresponding ngx_trnalsate/Core, @ngx-translate/http-loader and Angular at https://www.npmjs.com/package/@ngx-translate/core

Eg: For Angular 6.X versions,

npm install @ngx-translate/core@10 @ngx-translate/http-loader@3 rxjs --save

Like as above, follow below command and rest of code part is common for all versions(Note: Version can obtain from( https://www.npmjs.com/package/@ngx-translate/core)

npm install @ngx-translate/core@version @ngx-translate/http-loader@version rxjs --save

Do your child forms really need to be Forms? Could they be user controls instead? This way, they could easily raise events for the main form to handle and you could better encapsulate their logic into a single class (at least, logically, they are after all classes already).

@Lars: You are right here. This was something I did in my very beginning days and have not had to do it since, that is why I first suggested raising an event, but my other method would really break any semblance of encapsulation.

@Rob: Yup, sounds about right :). 0/2 on this one...

On the windows platform, I met that problem too The solution for me is just add

C:\Windows\System32

to the PATH

and restart the computer.

In bash, I used this libreoffice command to convert all my xlsx files in the current directory:

for i   in *.xlsx; do  libreoffice --headless --convert-to csv "$i" ; done

It takes care of spaces in the filename.

Tried again some years later, and it didn't work. This thread gives some tips, but the quickiest solution was to run as root (or running a sudo libreoffice). Not elegant, but quick.

Use the command scalc.exe in Windows

For me

grep -b "searchsomething" *.log

worked as I wanted

std::stringstream::str() is the method you are looking for.

With std::stringstream:

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::stringstream ss;
    ss << NumericValue;
    return ss.str();
}

std::stringstream is a more generic tool. You can use the more specialized class std::ostringstream for this specific job.

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::ostringstream oss;
    oss << NumericValue;
    return oss.str();
}

If you are working with std::wstring type of strings, you must prefer std::wstringstream or std::wostringstream instead.

template <class T>
std::wstring YourClass::NumericToString(const T & NumericValue)
{
    std::wostringstream woss;
    woss << NumericValue;
    return woss.str();
}

if you want the character type of your string could be run-time selectable, you should also make it a template variable.

template <class CharType, class NumType>
std::basic_string<CharType> YourClass::NumericToString(const NumType & NumericValue)
{
    std::basic_ostringstream<CharType> oss;
    oss << NumericValue;
    return oss.str();
}

For all the methods above, you must include the following two header files.

#include <string>
#include <sstream>

Note that, the argument NumericValue in the examples above can also be passed as std::string or std::wstring to be used with the std::ostringstream and std::wostringstream instances respectively. It is not necessary for the NumericValue to be a numeric value.

I suggest to use a container for each img p like this:

<div class="image123">
    <div style="float:left;margin-right:5px;">
        <img src="/images/tv.gif" height="200" width="200"  />
        <p style="text-align:center;">This is image 1</p>
    </div>
    <div style="float:left;margin-right:5px;">
        <img class="middle-img" src="/images/tv.gif/" height="200" width="200" />
        <p style="text-align:center;">This is image 2</p>
    </div>
    <div style="float:left;margin-right:5px;">
        <img src="/images/tv.gif/" height="200" width="200" />
        <p style="text-align:center;">This is image 3</p>
    </div>
</div>

Then apply float:left to each container. I add and 5px margin right so there is a space between each image. Also alway close your elements. Maybe in html img tag is not important to close but in XHTML is.

fiddle

Also a friendly advice. Try to avoid inline styles as much as possible. Take a look here:

html

<div class="image123">
    <div>
        <img src="/images/tv.gif" />
        <p>This is image 1</p>
    </div>
    <div>
        <img class="middle-img" src="/images/tv.gif/" />
        <p>This is image 2</p>
    </div>
    <div>
        <img src="/images/tv.gif/" />
        <p>This is image 3</p>
    </div>
</div>

css

div{
    float:left;
    margin-right:5px;
}

div > img{
   height:200px;
    width:200px;
}

p{
    text-align:center;
}

It's generally recommended that you use linked style sheets because:

• They can be cached by browsers for performance
• Generally a lot easier to maintain for a development perspective

To achieve it, you have to modify the background-color of the element.

Ways to create a (semi-) transparent color:

• The CSS color name transparent creates a completely transparent color.

  Usage:

    .transparent{
      background-color: transparent;
    }
  

• Using rgba or hsla color functions, that allow you to add the alpha channel (opacity) to the rgb and hsl functions. Their alpha values range from 0 - 1.

  Usage:

    .semi-transparent-yellow{
      background-color: rgba(255, 255, 0, 0.5);
    }
    .transparent{
      background-color:  hsla(0, 0%, 0%, 0);
    }
  

• Besides the already mentioned solutions, you can also use the HEX format with alpha value (#RRGGBBAA or #RGBA notation).

  That's pretty new (contained by CSS Color Module Level 4), but already implemented in larger browsers (sorry, no IE).

  This differs from the other solutions, as this treats the alpha channel (opacity) as a hexadecimal value as well, making it range from 0 - 255 (FF).

  Usage:

    .semi-transparent-yellow{
      background-color: #FFFF0080;
    }
    .transparent{
      background-color: #0000;
    }
  

You can try them out as well:

• transparent:

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: transparent;
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `transparent`
</div>

• rgba():

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: rgba(0, 255, 0, 0.3);
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `rgba()`
</div>

• #RRGGBBAA:

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: #FF000060
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `#RRGGBBAA`
</div>

what about having the image be something selected by the user? Use a input:file tag and then after they select the image, show it on the clientside webpage? That is doable for most things. Right now i am trying to get it working for IE, but as with all microsoft products, it is a cluster fork().

As pointed out by others, your problem is that you have not declared an array

Below I've tried to recreate your program so that it works as you intended. I tried to leave as much as possible as it was (such as leaving your array as a variant)

Public Sub Testprog()
    '"test()" is an array, "test" is not
    Dim test() As Variant
    'I am assuming that iCounter is the array size
    Dim iCounter As Integer

    '"On Error Resume Next" just makes us skip over a section that throws the error
    On Error Resume Next

    'if test() has not been assigned a UBound or LBound yet, calling either will throw an error
    '   without an LBound and UBound an array won't hold anything (we will assign them later)

    'Array size can be determined by (UBound(test) - LBound(test)) + 1
    If (UBound(test) - LBound(test)) + 1 > 0 Then
        iCounter = (UBound(test) - LBound(test)) + 1

        'So that we don't run the code that deals with UBound(test) throwing an error
        Exit Sub
    End If

    'All the code below here will run if UBound(test)/LBound(test) threw an error
    iCounter = 0

    'This makes LBound(test) = 0
    '   and UBound(test) = iCounter where iCounter is 0
    '   Which gives us one element at test(0)
    ReDim Preserve test(0 To iCounter)

    test(iCounter) = "test"
End Sub

here is your method

public int lastDigit(int number)
{
    //your code goes here. 
    int last =number%10;
    return last;
}

This a terrible thing! It costs my a few hours! this is my table rows :

private String USER_ID = "user_id";
private String REMEMBER_UN = "remember_un";
private String REMEMBER_PWD = "remember_pwd";
private String HEAD_URL = "head_url";
private String USER_NAME = "user_name";
private String USER_PPU = "user_ppu";
private String CURRENT_TIME = "current_time";

Cursor c = db.rawQuery("SELECT * FROM " + TABLE +" ORDER BY " + CURRENT_TIME + " DESC",null);

Every time when I update the table , I will update the CURRENT_TIME for sort. But I found that it is not work.The result is not sorted what I want. Finally, I found that, the column "current_time" is the default row of sqlite.

The solution is, rename the column "cur_time" instead of "current_time".

You can put in this directory your Xampp control panel shortcut it will work fine (it will automatically start after windows startup) as @wajahat-hashmi answered above:

C:\Users\User-Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

About aditional windows script or programs that we need to run automatically...

I needed to create some additional scripts to initialize some windows services. If someone has the same need you can put in that same directory, they will all run right after windows startup.

For me, Xampp auto start and other scripts and shortcuts worked fine in windows 8.1, I think it will work fine in any windows version.

I hope it works well for anyone who has the same need.

You can also try Word Extractor tool. Word Extractor can be used with any file in your computer to separate the strings that contain human text / words from binary code (exe applications, DLLs).

I want to alert('test'); in an input type text but it should not execute the alert(alert prompt).

<input type="text" value="<script>alert('test');</script>" />

Produces:

You can do this programatically via JavaScript. First obtain a reference to the input element, then set the value attribute.

var inputElement = document.querySelector("input");
inputElement.value = "<script>alert('test');<\/script>";

If you've just inserted a record into the Customers table and you need the value of the recently populated ID field, you can use the SCOPE_IDENTITY function. This is only useful when the INSERT has occurred within the same scope as the call to SCOPE_IDENTITY.

INSERT INTO Customers(ID, FirstName, LastName)
Values
(23, 'Bob', 'Smith')

SET @mostRecentId = SCOPE_IDENTITY()

This may or may not be useful for you, but it's a good technique to be aware of. It will also work with auto-generated columns.

Disabling content filtering

The easiest solution is going to the config.js and setting:

config.allowedContent = true;

(Remember to clear browser's cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features.

Configuring content filtering

You can also configure CKEditor's content filter more precisely to allow only these element, classes, styles and attributes which you need. This solution is much better, because CKEditor will still remove a lot of crappy HTML which browsers produce when copying and pasting content, but it will not strip the content you want.

For example, you can extend the default CKEditor's configuration to accept all div classes:

config.extraAllowedContent = 'div(*)';

Or some Bootstrap stuff:

config.extraAllowedContent = 'div(col-md-*,container-fluid,row)';

Or you can allow description lists with optional dir attributes for dt and dd elements:

config.extraAllowedContent = 'dl; dt dd[dir]';

These were just very basic examples. You can write all kind of rules - requiring attributes, classes or styles, matching only special elements, matching all elements. You can also disallow stuff and totally redefine CKEditor's rules. Read more about:

• Content filtering in CKEditor – why do you need content filter.
• Advanced Content Filter – in deep description of the filtering mechanism.
• Allowed content rules – how to write allowed content rules.

As stated from David Cournapeau, use figure().

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.figure()
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("first.ps")


plt.figure()
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

Or subplot(121) / subplot(122) for the same plot, different position.

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.subplot(121)
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")

plt.subplot(122)
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

The code below works for trusting self-signed certificates. You have to use the TrustSelfSignedStrategy when creating your client:

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
        sslsf).build();

HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
} finally {
    response.close();
}

I did not include the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER on purpose: The point was to allow testing with self signed certificates so you don't have to acquire a proper certificate from a certification authority. You can easily create a self-signed certificate with the correct host name, so do that instead of adding the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER flag.

You should not rely on a hash code being equal to a specific value. Just that it will return consistent results within the same execution. The API docs say the following :

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.

EDIT Since the javadoc for String.hashCode() specifies how a String's hash code is computed, any violation of this would violate the public API specification.

Duplicated id for pairs name and city:

select s.id, t.* 
from [stuff] s
join (
    select name, city, count(*) as qty
    from [stuff]
    group by name, city
    having count(*) > 1
) t on s.name = t.name and s.city = t.city

When you open the file you want to write to, open it with a specific encoding that can handle all the characters.

with open('filename', 'w', encoding='utf-8') as f:
    print(r['body'], file=f)

I ran speed tests on some of these answers for a long string and a short string. Clive Paterson's code won by a good bit, presumably because the others are taking into account serialization options. Here are my results:

And here is the test code:

public static void Main(string[] args)
{
    var testStr1 = "Apple Banana";
    var testStr2 = @"\\some\long\path\with\lots\of\things\to\escape\some\long\path\t\with\lots\of\n\things\to\escape\some\long\path\with\lots\of\""things\to\escape\some\long\path\with\lots""\of\things\to\escape";

    foreach (var testStr in new[] { testStr1, testStr2 })
    {
        var results = new Dictionary<string,List<long>>();

        for (var n = 0; n < 10; n++)
        {
            var count = 1000 * 1000;

            var sw = Stopwatch.StartNew();
            for (var i = 0; i < count; i++)
            {
                var s = System.Web.HttpUtility.JavaScriptStringEncode(testStr);
            }
            var t = sw.ElapsedMilliseconds;
            results.GetOrCreate("System.Web.HttpUtility.JavaScriptStringEncode").Add(t);

            sw = Stopwatch.StartNew();
            for (var i = 0; i < count; i++)
            {
                var s = System.Web.Helpers.Json.Encode(testStr);
            }
            t = sw.ElapsedMilliseconds;
            results.GetOrCreate("System.Web.Helpers.Json.Encode").Add(t);

            sw = Stopwatch.StartNew();
            for (var i = 0; i < count; i++)
            {
                var s = Newtonsoft.Json.JsonConvert.ToString(testStr);
            }
            t = sw.ElapsedMilliseconds;

            sw = Stopwatch.StartNew();

            results.GetOrCreate("Clive Paterson").Add(t);
        }

        Console.WriteLine(testStr);
        foreach (var result in results)
        {
            Console.WriteLine(result.Key + ": " + Math.Round(result.Value.Skip(1).Average()) + "ms");
        }
        Console.WriteLine();

You can use GNU awk:

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

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

You've used text-decoration none in the wrong selector. You need to check which tag do you need for decoration none.

You may use this code

.boxhead h2 a{text-decoration: none;}

OR

.boxhead a{text-decoration: none !important;}

OR

a{text-decoration: none !important;}

Try this:

var frm = document.getElementById('search-theme-form') || null;
if(frm) {
   frm.action = 'whatever_you_need.ext' 
}

With momentjs "fromNow" method, This allows you to work with formatted date, ie: 03/15/1968

var dob = document.getElementByID("dob"); var age = moment(dob.value).fromNow(true).replace(" years", "");

//fromNow(true) => suffix "ago" is not displayed //but we still have to get rid of "years";

As a prototype version

String.prototype.getAge = function() {
return moment(this.valueOf()).fromNow(true).replace(" years", "");

}

I used the following query to retrieve the information of constraints in the SQL Server 2012, and works perfectly. I hope it would be useful for you.

    ,CASE WHEN clmns.is_nullable = 0 THEN 'NO' ELSE 'YES' END AS [Column Nullable]
    ,CASE WHEN clmns.is_identity = 0 THEN 'NO' ELSE 'YES' END AS [Column IS IDENTITY]

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E

All You have to do is git push origin master, where origin is the default name (alias) of Your remote repository and master is the remote branch You want to push Your changes to.

You may also want to check these out:

1. http://gitimmersion.com/
2. http://progit.org/book/

The problem is that the execution policy is set on a per user basis. You'll need to run the following command in your application every time you run it to enable it to work:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned

There probably is a way to set this for the ASP.NET user as well, but this way means that you're not opening up your whole system, just your application.

Have you tried: getElementbyId('ID_OF_ID').innerHTML?

Small change to the recursion to so you can for example find the child tab control of a tab control.

    public static DependencyObject FindInVisualTreeDown(DependencyObject obj, Type type)
    {

        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild(obj, i);

                if (child.GetType() == type)
                {
                    return child;
                }

                DependencyObject childReturn = FindInVisualTreeDown(child, type);
                if (childReturn != null)
                {
                    return childReturn;

When installing Wamperserver 3 on windows 10, it now gives a nice big warning during the install telling you it won't work unless you install many of these packages.

It worked for me after I followed the instructions and then restart the computer and reinstalled.

--- Installation of Wampserver --- BEFORE proceeding with the installation of Wampserver, you must ensure that certain elements are installed on your system, otherwise Wampserver will absolutely not run, and in addition, the installation will be faulty and you need to remove Wampserver BEFORE installing the elements that were missing. Make sure you are "up to date" in the redistributable packages VC9, VC10, VC11, VC13 , VC14 and VC15 See --- Visual C++ Packages below.

--- Do not install Wampserver OVER an existing version, follow the advice: - Install a new version of Wampserver: http://forum.wampserver.com/read.php?2,123606 If you install Wampserver over an existing version, not only it will not work, but you risk losing your existing databases.

--- Install Wampserver in a folder at the root of a disk, for example C:\wamp or D:\wamp. Take an installation path that does not include spaces or diacritics; Therefore, no installation in c: \ Program Files\ or C: \ Program Files (x86\ We must BEFORE installing, disable or close some applications: - Close Skype or force not to use port 80 Item No. 04 of the Wampserver TROUBLESHOOTING TIPS:http://forum.wampserver.com/read.php?2,134915 - Disable IIS Item No. 08 of the Wampserver TROUBLESHOOTING TIPS:http://forum.wampserver.com/read.php?2,134915 If these prerequisites are not in place, Press the Cancel button to cancel the installation, then apply the prerequisites and restart the installation. This program requires Administrator privileges to function properly. It will be launched with the "Run as administrator" option. If you do not want a program to have this option, cancel the installation.

--- Visual C++ Packages --- The MSVC runtime libraries VC9, VC10, VC11 are required for Wampserver 2.4, 2.5 and 3.0, even if you use only Apache and PHP versions with VC11. Runtimes VC13, VC14 is required for PHP 7 and Apache 2.4.17 or more

Because this compatibility the version number of the Redistributable is 14.1x.xx and after you install the Redistributable VC2017, VC2015 is removed but you can still use VC14.

If you have a 64-bit Windows, you must install both 32 and 64bit versions of each VisualC++ package, even if you do not use Wampserver 64 bit To verify that all VC ++ packages are installed and with the latest versions, you can use the tool: http://wampserver.aviatechno.net/files/tools/check_vcredist.exe and you will find all the packages on http://wampserver.aviatechno.net/ in section Visual C++ Redistribuable Packages You must install each package "as an administrator", so right-click the exe file and then run as Administrator. Do not use a previously loaded tool. Make a new download to make sure you are using the correct version.

Warning: Sometimes Microsoft may update the VC ++ package by breaking the download links and without redirect to the new. If the case happens to you, remember that item number 20 below will be updated and the page http://wampserver.aviatechno.net/ section Visual C++ Redistribuable Packages is up to date.

Two important pitfalls

which were ignored by other answers so far:

1. Trailing newline removal from command expansion
2. NUL character removal

Trailing newline removal from command expansion

This is a problem for the:

value="$(cat config.txt)"

type solutions, but not for read based solutions.

Command expansion removes trailing newlines:

S="$(printf "a\n")"
printf "$S" | od -tx1

Outputs:

0000000 61
0000001

This breaks the naive method of reading from files:

FILE="$(mktemp)"
printf "a\n\n" > "$FILE"
S="$(<"$FILE")"
printf "$S" | od -tx1
rm "$FILE"

POSIX workaround: append an extra char to the command expansion and remove it later:

S="$(cat $FILE; printf a)"
S="${S%a}"
printf "$S" | od -tx1

Outputs:

0000000 61 0a 0a
0000003

Almost POSIX workaround: ASCII encode. See below.

NUL character removal

There is no sane Bash way to store NUL characters in variables.

This affects both expansion and read solutions, and I don't know any good workaround for it.

Example:

printf "a\0b" | od -tx1
S="$(printf "a\0b")"
printf "$S" | od -tx1

Outputs:

0000000 61 00 62
0000003

0000000 61 62
0000002

Ha, our NUL is gone!

Workarounds:

• ASCII encode. See below.

• use bash extension $"" literals:

  S=$"a\0b"
  printf "$S" | od -tx1
  

  Only works for literals, so not useful for reading from files.

Workaround for the pitfalls

Store an uuencode base64 encoded version of the file in the variable, and decode before every usage:

FILE="$(mktemp)"
printf "a\0\n" > "$FILE"
S="$(uuencode -m "$FILE" /dev/stdout)"
uudecode -o /dev/stdout <(printf "$S") | od -tx1
rm "$FILE"

Output:

0000000 61 00 0a
0000003

uuencode and udecode are POSIX 7 but not in Ubuntu 12.04 by default (sharutils package)... I don't see a POSIX 7 alternative for the bash process <() substitution extension except writing to another file...

Of course, this is slow and inconvenient, so I guess the real answer is: don't use Bash if the input file may contain NUL characters.

Just for the records the analogous java version:

Tuple2<String, String> sc[] = sparkConf.getAll();
for (int i = 0; i < sc.length; i++) {
    System.out.println(sc[i]);
}

if setting height to 100% doesn't work, try min-height=100% for div. You still have to set the html tag.

html {
    height: 100%;
    margin: 0px;
    padding: 0px;
    position: relative;
}

#fullHeight{

    width: 450px;
    **min-height: 100%;**
    background-color: blue;

}

On Android the color can be declared in the following format

#AARRGGBB

AA - is the bit that’s of most interest to us, it stands for alpha channel

RR GG BB - red, green & blue channels respectively

Now in order to add transparency to our color we need to prepend it with hexadecimal value representing the alpha (transparency).

For example if you want to set 80% transparency value to black color (#000000) you need to prepend it with CC, as a result we end up with the following color resource #CC000000.

You can read about it in more detail on my blog https://androidexplained.github.io/android/ui/2020/10/12/hex-color-code-transparency.html

I've tried to summarize the various answers here, updated for PowerShell 5:

• If you're only using PowerShell 3 or higher, use $PSCommandPath

• If want compatibility with older versions, insert the shim:

  if ($PSCommandPath -eq $null) { function GetPSCommandPath() { return $MyInvocation.PSCommandPath; } $PSCommandPath = GetPSCommandPath; }

  This adds $PSCommandPath if it doesn't already exist.

  The shim code can be executed anywhere (top-level or inside a function), though $PSCommandPath variable is subject to normal scoping rules (eg, if you put the shim in a function, the variable is scoped to that function only).

Details

There's 4 different methods used in various answers, so I wrote this script to demonstrate each (plus $PSCommandPath):

function PSCommandPath() { return $PSCommandPath; }
function ScriptName() { return $MyInvocation.ScriptName; }
function MyCommandName() { return $MyInvocation.MyCommand.Name; }
function MyCommandDefinition() {
    # Begin of MyCommandDefinition()
    # Note: ouput of this script shows the contents of this function, not the execution result
    return $MyInvocation.MyCommand.Definition;
    # End of MyCommandDefinition()
}
function MyInvocationPSCommandPath() { return $MyInvocation.PSCommandPath; }

Write-Host "";
Write-Host "PSVersion: $($PSVersionTable.PSVersion)";
Write-Host "";
Write-Host "`$PSCommandPath:";
Write-Host " *   Direct: $PSCommandPath";
Write-Host " * Function: $(PSCommandPath)";
Write-Host "";
Write-Host "`$MyInvocation.ScriptName:";
Write-Host " *   Direct: $($MyInvocation.ScriptName)";
Write-Host " * Function: $(ScriptName)";
Write-Host "";
Write-Host "`$MyInvocation.MyCommand.Name:";
Write-Host " *   Direct: $($MyInvocation.MyCommand.Name)";
Write-Host " * Function: $(MyCommandName)";
Write-Host "";
Write-Host "`$MyInvocation.MyCommand.Definition:";
Write-Host " *   Direct: $($MyInvocation.MyCommand.Definition)";
Write-Host " * Function: $(MyCommandDefinition)";
Write-Host "";
Write-Host "`$MyInvocation.PSCommandPath:";
Write-Host " *   Direct: $($MyInvocation.PSCommandPath)";
Write-Host " * Function: $(MyInvocationPSCommandPath)";
Write-Host "";

Output:

PS C:\> .\Test\test.ps1

PSVersion: 5.1.19035.1

$PSCommandPath:
 *   Direct: C:\Test\test.ps1
 * Function: C:\Test\test.ps1

$MyInvocation.ScriptName:
 *   Direct:
 * Function: C:\Test\test.ps1

$MyInvocation.MyCommand.Name:
 *   Direct: test.ps1
 * Function: MyCommandName

$MyInvocation.MyCommand.Definition:
 *   Direct: C:\Test\test.ps1
 * Function:
    # Begin of MyCommandDefinition()
    # Note this is the contents of the MyCommandDefinition() function, not the execution results
    return $MyInvocation.MyCommand.Definition;
    # End of MyCommandDefinition()


$MyInvocation.PSCommandPath:
 *   Direct:
 * Function: C:\Test\test.ps1

Notes:

• Executed from C:\, but actual script is C:\Test\test.ps1.
• No method tells you the passed invocation path (.\Test\test.ps1)
• $PSCommandPath is the only reliable way, but was introduced in PowerShell 3
• For versions prior to 3, no single method works both inside and outside of a function

If I understand correctly, you want to get the String of an Editable object, right? If yes, try using toString().

Hi using the following code its working...

onclick="window.open('privacy_policy.php','','width=1200,height=800,scrollbars=yes');

Previously i Entered like

onclick="window.open('privacy_policy.php','Window title','width=1200,height=800,scrollbars=yes');

Means Microsoft does not allow you to enter window name it should be blank in window.open function...

Thanks, Nilesh Pangul

2019 answer:

Some time has passed and I changed my approach now when building forms. I've done thousands of them till today and got really tired of typing id for every label/input pair, so this was flushed down the toilet. When you dive input right into the label, things work the same way, no ids necessary. I also took advantage of flexbox being, well, very flexible.

HTML:

<label>
  Short label <input type="text" name="dummy1" />
</label>

<label>
  Somehow longer label <input type="text" name="dummy2" />
</label>

<label>
  Very long label for testing purposes <input type="text" name="dummy3" />
</label>

CSS:

label {
  display: flex;
  flex-direction: row;
  justify-content: flex-end;
  text-align: right;
  width: 400px;
  line-height: 26px;
  margin-bottom: 10px;
}

input {
  height: 20px;
  flex: 0 0 200px;
  margin-left: 10px;
}

Fiddle DEMO

Original answer:

Use label instead of span. It's meant to be paired with inputs and preserves some additional functionality (clicking label focuses the input).

This might be exactly what you want:

HTML:

<label for="dummy1">title for dummy1:</label>
<input id="dummy1" name="dummy1" value="dummy1">

<label for="dummy2">longer title for dummy2:</label>
<input id="dummy2" name="dummy2" value="dummy2">

<label for="dummy3">even longer title for dummy3:</label>
<input id="dummy3" name="dummy3" value="dummy3">

CSS:

label {
    width:180px;
    clear:left;
    text-align:right;
    padding-right:10px;
}

input, label {
    float:left;
}

Reloading existing classes with existing data is likely to break things.

You can load new code into new class loaders relatively easily:

ClassLoader loader = URLClassLoader.newInstance(
    new URL[] { yourURL },
    getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();

Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans, etc).

If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.

Of course debugging systems can do fancier things, but are more hacky and less reliable.

It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.

The

Declaring Constants and Variables section of The Swift Programming Language documentation specifies the following:

You declare constants with the let keyword and variables with the var keyword.

Make sure to understand how this works for Reference types. Unlike Value Types, the object's underlying properties can change despite an instance of a reference type being declared as a constant. See the Classes are Reference Types section of the documentation, and look at the example where they change the frameRate property.

I have same error. Problem was that branch was deleted, released. But in PhpStorm I still could see it in remote branches. I could checkout as local branch. And then doing git pull was giving this error.

So need to check if this brnach really exists remotely.

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

I would install Microsoft Network Monitor, configure the tool so it would only see HTTP packets (filter the port) and start capturing packets.

There is no block comment in VB.NET.

You need to use a ' in front of every line you want to comment out.

In Visual Studio you can use the keyboard shortcuts that will comment/uncomment the selected lines for you:

Ctrl + K, C to comment

Ctrl + K, U to uncomment

It occurs when you don't specify the no of parameters the __init__() or any other method looking for.

For example:

class Dog:
    def __init__(self):
        print("IN INIT METHOD")

    def __unicode__(self,):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")

obj=Dog("JIMMY",1,2,3,"WOOF")

When you run the above programme, it gives you an error like that:

TypeError: __init__() takes 1 positional argument but 6 were given

How we can get rid of this thing?

Just pass the parameters, what __init__() method looking for

class Dog:
    def __init__(self, dogname, dob_d, dob_m, dob_y, dogSpeakText):
        self.name_of_dog = dogname
        self.date_of_birth = dob_d
        self.month_of_birth = dob_m
        self.year_of_birth = dob_y
        self.sound_it_make = dogSpeakText

    def __unicode__(self, ):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")


obj = Dog("JIMMY", 1, 2, 3, "WOOF")
print(id(obj))

If you check the API for List you'll notice it says:

Interface List<E>

Being an interface means it cannot be instantiated (no new List() is possible).

If you check that link, you'll find some classes that implement List:

All Known Implementing Classes:

AbstractList, AbstractSequentialList, ArrayList, AttributeList, CopyOnWriteArrayList, LinkedList, RoleList, RoleUnresolvedList, Stack, Vector

Those can be instantiated. Use their links to know more about them, I.E: to know which fits better your needs.

The 3 most commonly used ones probably are:

 List<String> supplierNames1 = new ArrayList<String>();
 List<String> supplierNames2 = new LinkedList<String>();
 List<String> supplierNames3 = new Vector<String>();

Bonus:
You can also instantiate it with values, in an easier way, using the Arrays class, as follows:

List<String> supplierNames = Arrays.asList("sup1", "sup2", "sup3");
System.out.println(supplierNames.get(1));

But note you are not allowed to add more elements to that list, as it's fixed-size.

Create a BufferedImage from file and make it TYPE_INT_RGB

import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class Main{
    public static void main(String args[]){
        try{
            BufferedImage img = new BufferedImage( 
                500, 500, BufferedImage.TYPE_INT_RGB );
            File f = new File("MyFile.png");
            int r = 5;
            int g = 25; 
            int b = 255;
            int col = (r << 16) | (g << 8) | b;
            for(int x = 0; x < 500; x++){
                for(int y = 20; y < 300; y++){
                    img.setRGB(x, y, col);
                }
            }
            ImageIO.write(img, "PNG", f); 
        }
        catch(Exception e){ 
            e.printStackTrace();
        }
    }
}

This paints a big blue streak across the top.

If you want it ARGB, do it like this:

    try{
        BufferedImage img = new BufferedImage( 
            500, 500, BufferedImage.TYPE_INT_ARGB );
        File f = new File("MyFile.png");
        int r = 255;
        int g = 10;
        int b = 57;
        int alpha = 255;
        int col = (alpha << 24) | (r << 16) | (g << 8) | b;
        for(int x = 0; x < 500; x++){
            for(int y = 20; y < 30; y++){
                img.setRGB(x, y, col);
            }
        }
        ImageIO.write(img, "PNG", f);
    }
    catch(Exception e){
        e.printStackTrace();
    }

Open up MyFile.png, it has a red streak across the top.

ADD <new column name> <data type> NOT NULL
GO
ALTER TABLE <table name> 
ADD CONSTRAINT <constraint name> DEFAULT <default value> FOR <new column name>
GO

Enclose <img> in <a> tag.

<a href="http://www.google.com.pk"><img src="smiley.gif"></a>

it will open link on same tab, and if you want to open link on new tab then use target="_blank"

<a href="http://www.google.com.pk" target="_blank"><img src="smiley.gif"></a>

Many of these answers do work, but I have found the easiest way by far is to send data through ViewData or ViewBag and let JSON.Net serialize it.

I use this technique when Javascript is needed for HTML generation before the page load or when AJAX overhead needs to be avoided:

In the controller:

public ActionResult MyController()
{
    var addresses = myAddressesGetter();
    ViewData["addresses"] = addresses ;
    return View();
}

In the view:

@section scripts {
<script type="text/javascript">
    var MyjavascriptAddresses: @Html.Raw(JsonConvert.SerializeObject(ViewData["addresses"])),
</script>
}

You can always rely on JSON.NET whereas some browsers have poor JSON deserialization support. Another benefit over some methods in that you can see the Javascript using your browser's View --> Source, since it is simply text generated server-side.

Note that In most situations, Web API a more elegant way to get JSON to the client.

All the info you'll ever need. Google is your friend.

Use uname -s to query the system name.

• Mac: Darwin

• Linux: various, LINUX for most

It's simple, get the character you want, and convert it to int.

String name = "admin";
int ascii = name.charAt(0);

Use following to call function of a frame in parent page

parent.document.getElementById('frameid').contentWindow.somefunction()

Here is a more concise way to achieve the "less insecure" method proposed by CoolAJ86

request({
  url: url,
  agentOptions: {
    rejectUnauthorized: false
  }
}, function (err, resp, body) {
  // ...
});

If you are having 112 columns in one single table and you would like to insert data from source table, you could do as

create table employees as select * from source_employees where employee_id=100;

Or from sqlplus do as

copy from source_schema/password insert employees using select * from 
source_employees where employee_id=100;

This alternative example stores the local time as Integer to save the 20 bytes. The work is done in the field default, Update-trigger, and View. strftime must use '%s' (single-quotes) because "%s" (double-quotes) threw a 'Not Constant' error on me.

Create Table Demo (
   idDemo    Integer    Not Null Primary Key AutoIncrement
  ,DemoValue Text       Not Null Unique
  ,DatTimIns Integer(4) Not Null Default (strftime('%s', DateTime('Now', 'localtime'))) -- get Now/UTC, convert to local, convert to string/Unix Time, store as Integer(4)
  ,DatTimUpd Integer(4)     Null
);

Create Trigger trgDemoUpd After Update On Demo Begin
  Update Demo Set
    DatTimUpd  =                          strftime('%s', DateTime('Now', 'localtime'))  -- same as DatTimIns
  Where idDemo = new.idDemo;
End;

Create View If Not Exists vewDemo As Select -- convert Unix-Times to DateTimes so not every single query needs to do so
   idDemo
  ,DemoValue
  ,DateTime(DatTimIns, 'unixepoch') As DatTimIns -- convert Integer(4) (treating it as Unix-Time)
  ,DateTime(DatTimUpd, 'unixepoch') As DatTimUpd --   to YYYY-MM-DD HH:MM:SS
From Demo;

Insert Into Demo (DemoValue) Values ('One');                      -- activate the field Default
-- WAIT a few seconds --    
Insert Into Demo (DemoValue) Values ('Two');                      -- same thing but with
Insert Into Demo (DemoValue) Values ('Thr');                      --   later time values

Update Demo Set DemoValue = DemoValue || ' Upd' Where idDemo = 1; -- activate the Update-trigger

Select * From    Demo;                                            -- display raw audit values

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

Encoding options for SHA256's 256 bits:

1. Base64: 6 bits per char = CHAR(44) including padding character
2. Hex: 4 bits per char = CHAR(64)
3. Binary: 8 bits per byte = BINARY(32)

IIS automatically defined .ttf as application/octet-stream which seems to work fine and fontshop recommends .woff to be defined as application/octet-stream

Its more than just setting the connection to null. That may be what the documentation says, but that is not the truth for mysql. The connection will stay around for a bit longer (Ive heard 60s, but never tested it)

If you want to here the full explanation see this comment on the connections https://www.php.net/manual/en/pdo.connections.php#114822

To force the close the connection you have to do something like

$this->connection = new PDO();
$this->connection->query('KILL CONNECTION_ID()');
$this->connection = null;

MyClass.class.getDeclaredConstructor(String.class).newInstance("HERESMYARG");

or

obj.getClass().getDeclaredConstructor(String.class).newInstance("HERESMYARG");

I will say no.

But the only proof that I have is personal experience and the fact that documentation on line continuation doesn't have anything else in it.

There are several ways to do it. The simplest is using \t in your text. However, it's possible that \t doesn't work in some situations, like PdfReport nuget package.

Short answer: You can't.

Long answer:

Due to the way generics is implemented in Java, the generic type T is not kept at runtime. Still, you can use a private data member:

public class Foo<T> 
{
    private Class<T> type;

    public Foo(Class<T> type) { this.type = type; } 
}

Usage example:

Foo<Integer> test = new Foo<Integer>(Integer.class);

Strings are immutable in Python, which means once a string is created, you cannot alter the contents of the strings. If at all, you need to change it, a new instance of the string will be created with the alterations.

Having that in mind, we have so many ways to solve this

1. Using str.replace,

   >>> "it is icy".replace("i", "")
   't s cy'
   

2. Using str.translate,

   >>> "it is icy".translate(None, "i")
   't s cy'
   

3. Using Regular Expression,

   >>> import re
   >>> re.sub(r'i', "", "it is icy")
   't s cy'
   

4. Using comprehension as a filter,

   >>> "".join([char for char in "it is icy" if char != "i"])
   't s cy'
   

5. Using filter function

   >>> "".join(filter(lambda char: char != "i", "it is icy"))
   't s cy'
   

Timing comparison

def findreplace(m_string, char):
    m_string = list(m_string)
    for k in m_string:
        if k == char:
            del(m_string[m_string.index(k)])
    return "".join(m_string)

def replace(m_string, char):
    return m_string.replace("i", "")

def translate(m_string, char):
    return m_string.translate(None, "i")

from timeit import timeit

print timeit("findreplace('it is icy','i')", "from __main__ import findreplace")
print timeit("replace('it is icy','i')", "from __main__ import replace")
print timeit("translate('it is icy','i')", "from __main__ import translate")

Result

1.64474582672
0.29278588295
0.311302900314

str.replace and str.translate methods are 8 and 5 times faster than the accepted answer.

Note: Comprehension method and filter methods are expected to be slower, for this case, since they have to create list and then they have to be traversed again to construct a string. And re is a bit overkill for a single character replacement. So, they all are excluded from the timing comparison.

In my case, I use below command:

git diff <branch name> -- <path + file name>

This command can help you compare same file in two different branches

Search for MySql.Data package, when you find it click on Install

Here is the sample controller which connects to MySql database using the mysql package. We mainly make use of MySqlConnection connection object.

 public class HomeController : Controller
{
    public ActionResult Index()
    {
        List<employeemodel> employees = new List<employeemodel>();
        string constr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            string query = "SELECT EmployeeId, Name, Country FROM Employees";
            using (MySqlCommand cmd = new MySqlCommand(query))
            {
                cmd.Connection = con;
               con.Open();
                using (MySqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        employees.Add(new EmployeeModel
                        {
                            EmployeeId = Convert.ToInt32(sdr["EmployeeId"]),
                            Name = sdr["Name"].ToString(),
                            Country = sdr["Country"].ToString()
                        });
                    }
                }
                con.Close();
            }
        }

        return View(employees);
    }
}

This one works well on Red Hat Linux (RHEL), macOS, BSD and some AIXes:

ps -T $$ | awk 'NR==2{print $NF}' 

alternatively, the following one should also work if pstree is available,

pstree | egrep $$ | awk 'NR==2{print $NF}'

1. Check if compatible Mysql for your PHP version is correctly installed. (eg. mysql-installer-community-5.5.40.1.msi for PHP 5.2.10, apache 2.2 and phpMyAdmin 3.5.2)
2. In your php\php.ini set your loadable php extensions path (eg. extension_dir = "C:\php\ext") (https://drive.google.com/open?id=1DDZd06SLHSmoFrdmWkmZuXt4DMOPIi_A)
3. (In your php\php.ini) check if extension=php_mysqli.dll is uncommented (https://drive.google.com/open?id=17DUt1oECwOdol8K5GaW3tdPWlVRSYfQ9)
4. Set your php folder (eg."C:\php") and php\ext folder (eg."C:\php\ext") as your runtime environment variable path (https://drive.google.com/open?id=1zCRRjh1Jem_LymGsgMmYxFc8Z9dUamKK)
5. Restart apache service (https://drive.google.com/open?id=1kJF5kxPSrj3LdKWJcJTos9ecKFx0ORAW)

As discussed, there are several ways to search:

/pattern
?pattern
* (and g*, which I sometimes use in macros)
# (and g#)

plus, navigating prev/next with N and n.

You can also edit/recall your search history by pulling up the search prompt with / and then cycle with C-p/C-n. Even more useful is q/, which takes you to a window where you can navigate the search history.

Also for consideration is the all-important 'hlsearch' (type :hls to enable). This makes it much easier to find multiple instances of your pattern. You might even want make your matches extra bright with something like:

hi Search ctermfg=yellow ctermbg=red guifg=...

But then you might go crazy with constant yellow matches all over your screen. So you’ll often find yourself using :noh. This is so common that a mapping is in order:

nmap <leader>z :noh<CR>

I easily remember this one as z since I used to constantly type /zz<CR> (which is a fast-to-type uncommon occurrence) to clear my highlighting. But the :noh mapping is way better.

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class UserAuthPubKey {
    public static void main(String[] arg) {
        try {
            JSch jsch = new JSch();

            String user = "tjill";
            String host = "192.18.0.246";
            int port = 10022;
            String privateKey = ".ssh/id_rsa";

            jsch.addIdentity(privateKey);
            System.out.println("identity added ");

            Session session = jsch.getSession(user, host, port);
            System.out.println("session created.");

            // disabling StrictHostKeyChecking may help to make connection but makes it insecure

            // session.setConfig(config);

            session.connect();
            System.out.println("session connected.....");

            Channel channel = session.openChannel("sftp");
            channel.setInputStream(System.in);
            channel.setOutputStream(System.out);
            channel.connect();
            System.out.println("shell channel connected....");

            ChannelSftp c = (ChannelSftp) channel;

            String fileName = "test.txt";
            c.put(fileName, "./in/");
            c.exit();
            System.out.println("done");

        } catch (Exception e) {
            System.err.println(e);
        }
    }
}

The ANSI escape sequences you're looking for are the Select Graphic Rendition subset. All of these have the form

\033[XXXm

where XXX is a series of semicolon-separated parameters.

To say, make text red, bold, and underlined (we'll discuss many other options below) in C you might write:

printf("\033[31;1;4mHello\033[0m");

In C++ you'd use

std::cout<<"\033[31;1;4mHello\033[0m";

In Python3 you'd use

print("\033[31;1;4mHello\033[0m")

and in Bash you'd use

echo -e "\033[31;1;4mHello\033[0m"

where the first part makes the text red (31), bold (1), underlined (4) and the last part clears all this (0).

As described in the table below, there are a large number of text properties you can set, such as boldness, font, underlining, &c. (Isn't it silly that StackOverflow doesn't allow you to put proper tables in answers?)

Font Effects

2-bit Colours

You've got this already!

4-bit Colours

The standards implementing terminal colours began with limited (4-bit) options. The table below lists the RGB values of the background and foreground colours used for these by a variety of terminal emulators:

Using the above, you can make red text on a green background (but why?) using:

\033[31;42m

11 Colours (An Interlude)

In their book "Basic Color Terms: Their Universality and Evolution", Brent Berlin and Paul Kay used data collected from twenty different languages from a range of language families to identify eleven possible basic color categories: white, black, red, green, yellow, blue, brown, purple, pink, orange, and gray.

Berlin and Kay found that, in languages with fewer than the maximum eleven color categories, the colors followed a specific evolutionary pattern. This pattern is as follows:

1. All languages contain terms for black (cool colours) and white (bright colours).
2. If a language contains three terms, then it contains a term for red.
3. If a language contains four terms, then it contains a term for either green or yellow (but not both).
4. If a language contains five terms, then it contains terms for both green and yellow.
5. If a language contains six terms, then it contains a term for blue.
6. If a language contains seven terms, then it contains a term for brown.
7. If a language contains eight or more terms, then it contains terms for purple, pink, orange or gray.

This may be why story Beowulf only contains the colours black, white, and red. It may also be why the Bible does not contain the colour blue. Homer's Odyssey contains black almost 200 times and white about 100 times. Red appears 15 times, while yellow and green appear only 10 times. (More information here)

Differences between languages are also interesting: note the profusion of distinct colour words used by English vs. Chinese. However, digging deeper into these languages shows that each uses colour in distinct ways. (More information)

Generally speaking, the naming, use, and grouping of colours in human languages is fascinating. Now, back to the show.

8-bit (256) colours

Technology advanced, and tables of 256 pre-selected colours became available, as shown below.

Using these above, you can make pink text like so:

\033[38;5;206m     #That is, \033[38;5;<FG COLOR>m

And make an early-morning blue background using

\033[48;5;57m      #That is, \033[48;5;<BG COLOR>m

And, of course, you can combine these:

\033[38;5;206;48;5;57m

The 8-bit colours are arranged like so:

0x00-0x07:  standard colors (same as the 4-bit colours)
0x08-0x0F:  high intensity colors
0x10-0xE7:  6 × 6 × 6 cube (216 colors): 16 + 36 × r + 6 × g + b (0 = r, g, b = 5)
0xE8-0xFF:  grayscale from black to white in 24 steps

ALL THE COLOURS

Now we are living in the future, and the full RGB spectrum is available using:

\033[38;2;<r>;<g>;<b>m     #Select RGB foreground color
\033[48;2;<r>;<g>;<b>m     #Select RGB background color

So you can put pinkish text on a brownish background using

\033[38;2;255;82;197;48;2;155;106;0mHello

Support for "true color" terminals is listed here.

Much of the above is drawn from the Wikipedia page "ANSI escape code".

A Handy Script to Remind Yourself

Since I'm often in the position of trying to remember what colours are what, I have a handy script called: ~/bin/ansi_colours:

#!/usr/bin/python

print "\\033[XXm"

for i in range(30,37+1):
    print "\033[%dm%d\t\t\033[%dm%d" % (i,i,i+60,i+60);

print "\033[39m\\033[39m - Reset colour"
print "\\033[2K - Clear Line"
print "\\033[<L>;<C>H OR \\033[<L>;<C>f puts the cursor at line L and column C."
print "\\033[<N>A Move the cursor up N lines"
print "\\033[<N>B Move the cursor down N lines"
print "\\033[<N>C Move the cursor forward N columns"
print "\\033[<N>D Move the cursor backward N columns"
print "\\033[2J Clear the screen, move to (0,0)"
print "\\033[K Erase to end of line"
print "\\033[s Save cursor position"
print "\\033[u Restore cursor position"
print " "
print "\\033[4m  Underline on"
print "\\033[24m Underline off"
print "\\033[1m  Bold on"
print "\\033[21m Bold off"

This prints

1. First Possibility: The encrypted string in the Related Web.config File should be same as entered in the connection string (which is shown above) And also, when you change anything in the "Registry Editor" or regedit.exe (as written at Run), then after any change, close the registry editor and reset your Internet Information Services by typing IISRESET at Run. And then login to your environment.

2. Type Services.msc on run and check:

   1. Status of ASP.NET State Services is started. If not, then right click on it, through Properties, change its Startup type to automatic.

   2. Iris ReportManager Service of that particular bank is Listed as Started or not. If its Running, It will show "IRIS REPORT MANAGER SERVICE" as started in the list. If not, then run it by clicking IRIS.REPORTMANAGER.EXE

   Then Again RESET IIS

OPTIONS request are by no means an AngularJS bug, this is how Cross-Origin Resource Sharing standard mandates browsers to behave. Please refer to this document: https://developer.mozilla.org/en-US/docs/HTTP_access_control, where in the "Overview" section it says:

The Cross-Origin Resource Sharing standard works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. Additionally, for HTTP request methods that can cause side-effects on user data (in particular; for HTTP methods other than GET, or for POST usage with certain MIME types). The specification mandates that browsers "preflight" the request, soliciting supported methods from the server with an HTTP OPTIONS request header, and then, upon "approval" from the server, sending the actual request with the actual HTTP request method. Servers can also notify clients whether "credentials" (including Cookies and HTTP Authentication data) should be sent with requests.

It is very hard to provide a generic solution that would work for all the WWW servers as setup will vary depending on the server itself and HTTP verbs that you intend to support. I would encourage you to get over this excellent article (http://www.html5rocks.com/en/tutorials/cors/) that has much more details on the exact headers that needs to be sent by a server.

You can use react-native-view-overflow plugin for placing a view on top of another. It works like the CSS z-index property.

import ViewOverflow from 'react-native-view-overflow';

      <View style={[styles2.cardContent]}>
        <Text style={styles2.text}>overflow: "visible"</Text>
      </View>

from the API docs:

player.stopVideo()

so in jQuery:

$('#playerID').get(0).stopVideo();

I see one problem with std::make_shared, it doesn't support private/protected constructors

CASE LEN('TestPerson')
    WHEN 0 THEN co.personentered  = co.personentered ELSE co.personentered LIKE '%TestPerson'

Try the following:

... and ( 
    (LEN('TestPerson') = 0 and co.personentered  = co.personentered) or
    (LEN('TestPerson') <> 0 and co.personentered LIKE '%TestPerson') ) and ...

In addition to what jgr208 said, you may have a ~/.profile file already and ~/.bash_profile may not be present, as was the case with me.

In this case, add setterm -blength 0 to the .profile.

If you create a .bash_profile, your .profile will be ignored and anything Windows wrote there will not work.

If you are trying to login with SQL credentials, you can also try changing the LoginMode for SQL Server in the registry to allow both SQL Server and Windows Authentication.

1. Open regedit
2. Go to the SQL instance key (may vary depending on your instance name): Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL14.SQLEXPRESS\MSSQLServer\
3. Set LoginMode to 2

4. Restart SQL service and SQL Server Management Studio and try again.

The default formatting is not very useful, in my opinion. I prefer ISO8601 as it's sortable, relatively compact and widely recognized:

>> require 'time'
=> true
>> Time.now.utc.iso8601
=> "2011-07-28T23:14:04Z"

In Angular 7 works perfect

HTML

<button (click)="scroll(target)">Click to scroll</button>
<div #target>Your target</div>

In component

scroll(el: HTMLElement) {
    el.scrollIntoView({behavior: 'smooth'});
}

modifying the proxy value under

[HKEY_USERS\<your SID>\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

doesnt need to restart ie

I was struggling with this one while using Visual Studio 2019 version 16.5.0.

What solved it finally:

• Close Visual Studio;
• Reopen Visual Studio;
• Make sure you right click the Solution if you have multiple projects and select Rebuild Solution.

Note that I tried doing a Rebuild Solution before and that did not catch the error. So it's important to close VS and reopen it.

It then showed the error that was causing add-migration command to fail with Build failed message.

Just don't set the height property in HighCharts and it will handle it dynamically for you so long as you set a height on the chart's containing element. It can be a fixed number or a even a percent if position is absolute.

Highcharts docs:

By default the height is calculated from the offset height of the containing element

Example: http://jsfiddle.net/wkkAd/149/

#container {
    height:100%;
    width:100%;
    position:absolute;
}

The timer has special functions.

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

if you use StartAsync () or Start (), the thread does not block the user interface element

     namespace UITimer


     {
        using thread = System.Threading;
        public class Timer
        {

        public event Action Tick;
        public event Action AsyncTick;
        public int Interval { get; set; } = 1;
        private bool canceled = false;
        private bool canceling = false;
        public async void Start()
        {
            while(true)
            {

                if (!canceled)
                {

                    }

                    Application.Current.Dispatcher.Invoke(AsyncTick);

=VLOOKUP(LEFT(A4,LEN(A4)-9),$D:$F,3,0)

I use this if my Lookup_Value needs to be truncated because of the format the name is in the Table_Array. E.g. my Lookup_Value is "Eastbay District", but the Table_Array list I have only shows this as "Eastbay". "Eastbay District" minus 9 characters will result in "Eastbay".

I hope this helps!

Demo link: https://github.com/RazvanSebastian/spring_multiple_log_files_demo.git

My solution is based on XML configuration using spring-boot-starter-log4j. The example is a basic example using spring-boot-starter and the two Loggers writes into different log files.
