As with everything in git there are multiple ways of doing it. The two commands you used are one way of doing it. Another thing you could have done is simply stash them with git stash -u. The -u makes sure that newly added files (untracked) are also included.

The handy thing about git stash -u is that

1. it is probably the simplest (only?) single command to accomplish your goal
2. if you change your mind afterwards you get all your work back with git stash pop (it's like deleting an email in gmail where you can just undo if you change your mind afterwards)

As of your other question git reset --hard won't remove the untracked files so you would still need the git clean -f. But a git stash -u might be the most convenient.

TL;DR version: remote-tracking branch origin/master used to exist, but does not now, so local branch source is tracking something that does not exist, which is suspicious at best—it means a different Git feature is unable to do anything for you—and Git is warning you about it. You have been getting along just fine without having the "upstream tracking" feature work as intended, so it's up to you whether to change anything.

For another take on upstream settings, see Why do I have to "git push --set-upstream origin <branch>"?

This warning is a new thing in Git, appearing first in Git 1.8.5. The release notes contain just one short bullet-item about it:

• "git branch -v -v" (and "git status") did not distinguish among a branch that is not based on any other branch, a branch that is in sync with its upstream branch, and a branch that is configured with an upstream branch that no longer exists.

To describe what it means, you first need to know about "remotes", "remote-tracking branches", and how Git handles "tracking an upstream". (Remote-tracking branches is a terribly flawed term—I've started using remote-tracking names instead, which I think is a slight improvement. Below, though, I'll use "remote-tracking branch" for consistency with Git documentation.)

Each "remote" is simply a name, like origin or octopress in this case. Their purpose is to record things like the full URL of the places from which you git fetch or git pull updates. When you use git fetch remote,¹ Git goes to that remote (using the saved URL) and brings over the appropriate set of updates. It also records the updates, using "remote-tracking branches".

A "remote-tracking branch" (or remote-tracking name) is simply a recording of a branch name as-last-seen on some "remote". Each remote is itself a Git repository, so it has branches. The branches on remote "origin" are recorded in your local repository under remotes/origin/. The text you showed says that there's a branch named source on origin, and branches named 2.1, linklog, and so on on octopress.

(A "normal" or "local" branch, of course, is just a branch-name that you have created in your own repository.)

Last, you can set up a (local) branch to "track" a "remote-tracking branch". Once local branch L is set to track remote-tracking branch R, Git will call R its "upstream" and tell you whether you're "ahead" and/or "behind" the upstream (in terms of commits). It's normal (even recommend-able) for the local branch and remote-tracking branches to use the same name (except for the remote prefix part), like source and origin/source, but that's not actually necessary.

And in this case, that's not happening. You have a local branch source tracking a remote-tracking branch origin/master.

You're not supposed to need to know the exact mechanics of how Git sets up a local branch to track a remote one, but they are relevant below, so I'll show how this works. We start with your local branch name, source. There are two configuration entries using this name, spelled branch.source.remote and branch.source.merge. From the output you showed, it's clear that these are both set, so that you'd see the following if you ran the given commands:

$ git config --get branch.source.remote
origin
$ git config --get branch.source.merge
refs/heads/master

Putting these together,² this tells Git that your branch source tracks your "remote-tracking branch", origin/master.

But now look at the output of git branch -a, which shows all the local and remote-tracking branch names in your repository. The remote-tracking names are listed under remotes/ ... and there is no remotes/origin/master. Presumably there was, at one time, but it's gone now.

Git is telling you that you can remove the tracking information with --unset-upstream. This will clear out both branch.source.origin and branch.source.merge, and stop the warning.

It seems fairly likely that what you want, though, is to switch from tracking origin/master, to tracking something else: probably origin/source, but maybe one of the octopress/ names.

You can do this with git branch --set-upstream-to,³ e.g.:

$ git branch --set-upstream-to=origin/source

(assuming you're still on branch "source", and that origin/source is the upstream you want—there is no way for me to tell which one, if any, you actually want, though).

(See also How do you make an existing Git branch track a remote branch?)

I think the way you got here is that when you first did a git clone, the thing you cloned-from had a branch master. You also had a branch master, which was set to track origin/master (this is a normal, standard setup for git). This meant you had branch.master.remote and branch.master.merge set, to origin and refs/heads/master. But then your origin remote changed its name from master to source. To match, I believe you also changed your local name from master to source. This changed the names of your settings, from branch.master.remote to branch.source.remote and from branch.master.merge to branch.source.merge ... but it left the old values, so branch.source.merge was now wrong.

It was at this point that the "upstream" linkage broke, but in Git versions older than 1.8.5, Git never noticed the broken setting. Now that you have 1.8.5, it's pointing this out.

That covers most of the questions, but not the "do I need to fix it" one. It's likely that you have been working around the broken-ness for years now, by doing git pull remote branch (e.g., git pull origin source). If you keep doing that, it will keep working around the problem—so, no, you don't need to fix it. If you like, you can use --unset-upstream to remove the upstream and stop the complaints, and not have local branch source marked as having any upstream at all.

The point of having an upstream is to make various operations more convenient. For instance, git fetch followed by git merge will generally "do the right thing" if the upstream is set correctly, and git status after git fetch will tell you whether your repo matches the upstream one, for that branch.

If you want the convenience, re-set the upstream.

¹git pull uses git fetch, and as of Git 1.8.4, this (finally!) also updates the "remote-tracking branch" information. In older versions of Git, the updates did not get recorded in remote-tracking branches with git pull, only with git fetch. Since your Git must be at least version 1.8.5 this is not an issue for you.

²Well, this plus a configuration line I'm deliberately ignoring that is found under remote.origin.fetch. Git has to map the "merge" name to figure out that the full local name for the remote-branch is refs/remotes/origin/master. The mapping almost always works just like this, though, so it's predictable that master goes to origin/master.

³Or, with git config. If you just want to set the upstream to origin/source the only part that has to change is branch.source.merge, and git config branch.source.merge refs/heads/source would do it. But --set-upstream-to says what you want done, rather than making you go do it yourself manually, so that's a "better way".

Yes, just delete the branch by running git push origin :branchname. To fix a new issue later, branch off from master again.

Combination of Dasha's and MMT solutions:

  Ext.getCmp('yourGridId').getView().ds.reload();

It is very useful when you want to perform an "ordered update".

MS SQL does not allow you to use ORDER BY with UPDATE, but with help of CTE you can do it that way:

WITH cte AS
(
    SELECT TOP(5000) message_compressed, message, exception_compressed, exception
    FROM logs
    WHERE Id >= 5519694 
    ORDER BY Id
)
UPDATE  cte
SET     message_compressed = COMPRESS(message), exception_compressed = COMPRESS(exception)

Look here for more info: How to update and order by using ms sql

This should also work and is a closer answer to what is asked in the question:

for i in range(len(x)):
    if valeur.item(i) <= 0.6:
        print ("this works")
    else:   
        print ("valeur is too high")

I use a percentage method to achieve

        border: 3px solid rgb(1, 1, 1);
        border-top-left-radius: 100% 200%;
        border-top-right-radius: 100% 200%;

In .NET you don't find only C#. You can find Visual Basic for example. If a job requires .NET knowledge, probably it need a programmer who knows the entire set of languages provided by the .NET framework.

protected void TestSubmit_ServerClick(object sender, EventArgs e)
{
  using (StreamWriter _testData = new StreamWriter(Server.MapPath("~/data.txt"), true))
 {
  _testData.WriteLine(TextBox1.Text); // Write the file.
 }         
}

Server.MapPath takes a virtual path and returns an absolute one. "~" is used to resolve to the application root.

If you want an argument that might appeal to a boss: Think about what a URL is. URLs are public. People copy and paste them. They share them, they put them on advertisements. Nothing prevents someone (knowingly or not) from mailing that URL around for other people to use. If your API key is in that URL, everybody has it.

The basic difference between Linear Regression and Logistic Regression is : Linear Regression is used to predict a continuous or numerical value but when we are looking for predicting a value that is categorical Logistic Regression come into picture.

Logistic Regression is used for binary classification.

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

You ignore case when you treat the data, not when you retrieve/store it. If you want to store everything in lowercase use String#toLowerCase, in uppercase use String#toUpperCase.

Then when you have to actually treat it, you may use out of the bow methods, like String#equalsIgnoreCase(java.lang.String). If nothing exists in the Java API that fulfill your needs, then you'll have to write your own logic.

I disagree with @Patrick's answer which, by quoting this doc, implicitly links OP's problem (Database is locked) to this:

Switching to another database backend. At a certain point SQLite becomes too "lite" for real-world applications, and these sorts of concurrency errors indicate you've reached that point.

This is a bit "too easy" to incriminate SQlite for this problem (which is very powerful when correctly used; it's not only a toy for small databases, fun fact: An SQLite database is limited in size to 140 terabytes).

Unless you have a very busy server with thousands of connections at the same second, the reason for this Database is locked error is probably more a bad use of the API, than a problem inherent to SQlite which would be "too light". Here are more informations about Implementation Limits for SQLite.

Now the solution:

I had the same problem when I was using two scripts using the same database at the same time:

• one was accessing the DB with write operations
• the other was accessing the DB in read-only

Solution: always do cursor.close() as soon as possible after having done a (even read-only) query.

Here are more details.

Although I don't know about asp.net mvc, but this is what we should do in a normal .net website. It should work for asp.net mvc also.

YourSessionClass obj=Session["key"] as YourSessionClass;
if(obj==null){
obj=new YourSessionClass();
Session["key"]=obj;
}

You would put this inside a method for easy access. HTH

document.ondomcontentready=function(){} should do the trick, but it doesn't have full browser compatibility.

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

Be careful, d is the list.

for (var i = 0; i < result.d.length; i++) { 
    alert(result.d[i].employeename);
}

Angular 2 Beta

This answer is for those who use Javascript for angularJS v.2.0 Beta.

To use ngModel in your view you should tell the angular's compiler that you are using a directive called ngModel.

How?

To use ngModel there are two libraries in angular2 Beta, and they are ng.common.FORM_DIRECTIVES and ng.common.NgModel.

Actually ng.common.FORM_DIRECTIVES is nothing but group of directives which are useful when you are creating a form. It includes NgModel directive also.

app.myApp = ng.core.Component({
    selector: 'my-app',
    templateUrl: 'App/Pages/myApp.html',
    directives: [ng.common.NgModel] // specify all your directives here
}).Class({
    constructor: function () {
        this.myVar = {};
        this.myVar.text = "Testing";
    },

});

Below approach of frame handling : When no id or name is given incase of nested frame

WebElement element =driver.findElement(By.xpath(".//*[@id='block-block19']//iframe"));
driver.switchTo().frame(element);
driver.findElement(By.xpath(".//[@id='carousel']/li/div/div[3]/a")).click();

ls | shuf -n 10 # ten random files

You can do something like this

var now = moment();
var time = now.hour() + ':' + now.minutes() + ':' + now.seconds();
time = time + ((now.hour()) >= 12 ? ' PM' : ' AM');

I usually use a dictionary, not a list to return JSON content.

import json

from django.http import HttpResponse

response_data = {}
response_data['result'] = 'error'
response_data['message'] = 'Some error message'

Pre-Django 1.7 you'd return it like this:

return HttpResponse(json.dumps(response_data), content_type="application/json")

For Django 1.7+, use JsonResponse as shown in this SO answer like so :

from django.http import JsonResponse
return JsonResponse({'foo':'bar'})

The overall winner between using the np.sum, np.min, and all seems to be np.min in terms of speed for large arrays:

N = 1000000
def func_sum(x):
    my_list = np.random.randn(N)
    return np.sum(my_list < x )==0

def func_min(x):
    my_list = np.random.randn(N)
    return np.min(my_list) >= x

def func_all(x):
    my_list = np.random.randn(N)
    return all(i >= x for i in my_list)

(i need to put the np.array definition inside the function, otherwise the np.min function remembers the value and does not do the computation again when testing for speed with timeit)

The performance of "all" depends very much on when the first element that does not satisfy the criteria is found, the np.sum needs to do a bit of operations, the np.min is the lightest in terms of computations in the general case.

When the criteria is almost immediately met and the all loop exits fast, the all function is winning just slightly over np.min:

>>> %timeit func_sum(10)
10 loops, best of 3: 36.1 ms per loop

>>> %timeit func_min(10)
10 loops, best of 3: 35.1 ms per loop

>>> %timeit func_all(10)
10 loops, best of 3: 35 ms per loop

But when "all" needs to go through all the points, it is definitely much worse, and the np.min wins:

>>> %timeit func_sum(-10)
10 loops, best of 3: 36.2 ms per loop

>>> %timeit func_min(-10)
10 loops, best of 3: 35.2 ms per loop

>>> %timeit func_all(-10)
10 loops, best of 3: 230 ms per loop

But using

np.sum(my_list<x)

can be very useful is one wants to know how many values are below x.

Can you not bind the datagridview to an empty collection (instead of null). That do the trick?

Another option to transform the static method into a static Func or Action. For instance.

Original code:

    class Math
    {
        public static int Add(int x, int y)
        {
            return x + y;
        }

You want to "mock" the Add method, but you can't. Change the above code to this:

        public static Func<int, int, int> Add = (x, y) =>
        {
            return x + y;
        };

Existing client code doesn't have to change (maybe recompile), but source stays the same.

Now, from the unit-test, to change the behavior of the method, just reassign an in-line function to it:

    [TestMethod]
    public static void MyTest()
    {
        Math.Add = (x, y) =>
        {
            return 11;
        };

Put whatever logic you want in the method, or just return some hard-coded value, depending on what you're trying to do.

This may not necessarily be something you can do each time, but in practice, I found this technique works just fine.

[edit] I suggest that you add the following Cleanup code to your Unit Test class:

    [TestCleanup]
    public void Cleanup()
    {
        typeof(Math).TypeInitializer.Invoke(null, null);
    }

Add a separate line for each static class. What this does is, after the unit test is done running, it resets all the static fields back to their original value. That way other unit tests in the same project will start out with the correct defaults as opposed your mocked version.

Include jQuery and use this code to get HTML of other website. Replace example.com with your website.

This method involves an external server fetching the sites HTML & sending it to you. :)

I think width: -moz-calc(25% - 1em); is what you are looking for. And you may want to give this Link a look for any further assistance

This will get you the drives on the machine:

System.IO.DriveInfo.GetDrives()

These two methods will get you the bad characters to check:

System.IO.Path.GetInvalidFileNameChars();
System.IO.Path.GetInvalidPathChars();

git grep

Here is the syntax using git grep combining multiple patterns using Boolean expressions:

git grep -e pattern1 --and -e pattern2 --and -e pattern3

^{The above command will print lines matching all the patterns at once.}

If the files aren't under version control, add --no-index param.

Search files in the current directory that is not managed by Git.

Check man git-grep for help.

Adding a class with a width of 90% to your input element and adding the following input-icon class to your span would achieve what you want I think.

.input { width: 90%; }
.input-icon {
    display: inline-block;
    height: 22px;
    width: 22px;
    line-height: 22px;
    text-align: center;
    color: #000;
    font-size: 12px;
    font-weight: bold;
    margin-left: 4px;
}

EDIT Per dan's suggestion, it would not be wise to use .input as the class name, some more specific would be advised. I was simply using .input as a generic placeholder for your css

Here you be able to get date like "2020-03-11T20:16:17" and return "11/Mar/2020 - 20:16"

 private String transformLocalDateTimeBrazillianUTC(String dateJson) throws  ParseException {
    String localDateTimeFormat = "yyyy-MM-dd'T'HH:mm:ss";
    SimpleDateFormat formatInput = new SimpleDateFormat(localDateTimeFormat);

    //Here is will set the time zone
    formatInput.setTimeZone(TimeZone.getTimeZone("UTC-03"));

    String brazilianFormat = "dd/MMM/yyyy - HH:mm";
    SimpleDateFormat formatOutput = new SimpleDateFormat(brazilianFormat);
    Date date = formatInput.parse(dateJson);
    return formatOutput.format(date);
}

this is what worked for me (yes I was having the same problem) were is says something like java -Xmx3G -Xms3G put java -Xmx1024M so the run.bat should look like java -Xmx1024M -jar craftbukkit.jar -o false PAUSE

Exception in thread "main" java.lang.NoClassDefFoundError  

One of the places java tries to find your .class file is your current directory. So if your .class file is in C:\java, you should change your current directory to that.

To change your directory, type the following command at the prompt and press Enter:

cd c:\java  

This . tells java that your classpath is your local directory.

Executing your program using this command should correct the problem:
java -classpath . HelloWorld  

I suggest you add separate overloaded method and add them to your projects Utility/Utilities class.

To check for Collection be empty or null

public static boolean isEmpty(Collection obj) {
    return obj == null || obj.isEmpty();
}

or use Apache Commons CollectionUtils.isEmpty()

To check if Map is empty or null

public static boolean isEmpty(Map<?, ?> value) {
    return value == null || value.isEmpty();
}

or use Apache Commons MapUtils.isEmpty()

To check for String empty or null

public static boolean isEmpty(String string) {
    return string == null || string.trim().isEmpty();
}

or use Apache Commons StringUtils.isBlank()

To check an object is null is easy but to verify if it's empty is tricky as object can have many private or inherited variables and nested objects which should all be empty. For that All need to be verified or some isEmpty() method be in all objects which would verify the objects emptiness.

What you can do too is usingtype() Example:

if type(inNumber) == int : print "This number is an int"
elif type(inNumber) == float : print "This number is a float"

as I learned while working with react.

• props are used by a component to get data from external environment i.e another component ( pure, functional or class) or a general class or javascript/typescript code

• states are used to manage the internal environment of a component means the data changes inside the component

You could search all the option values until it finds the correct one.

var defaultVal = "Country";
$("#select").find("option").each(function () {

    if ($(this).val() == defaultVal) {

        $(this).prop("selected", "selected");
    }
});

Update 03-Oct-19

new script that displays 10second countdown then launches chrome/chromiumn in fullscreen kiosk mode.

more updates to chrome required script update to allow autoplaying video with audio. Note --overscroll-history-navigation=0 isn't working currently will need to disable this flag by going to chrome://flags/#overscroll-history-navigation in your browser and setting to disabled.

@echo off
echo Countdown to application launch...
timeout /t 10
"C:\Program Files (x86)\chrome-win32\chrome.exe" --chrome --kiosk http://localhost/xxxx --incognito --disable-pinch --no-user-gesture-required --overscroll-history-navigation=0
exit

might need to set chrome://flags/#autoplay-policy if running an older version of chrome (60 below)

Update 11-May-16

There have been many updates to chrome since I posted this and have had to alter the script alot to keep it working as I needed.

Couple of issues with newer versions of chrome:

• built in pinch to zoom
• Chrome restore error always showing after forced shutdown
• auto update popup

Because of the restore error switched out to incognito mode as this launches a clear version all the time and does not save what the user was viewing and so if it crashes there is nothing to restore. Also the auto up in newer versions of chrome being a pain to try and disable I switched out to use chromium as it does not auto update and still gives all the modern features of chrome. Note make sure you download the top version of chromium this comes with all audio and video codecs as the basic version of chromium does not support all codecs.

Chromium download link

@echo off

echo Step 1 of 2: Waiting a few seconds before starting the Kiosk...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Step 2 of 5: Waiting a few more seconds before starting the browser...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Final 'invisible' step: Starting the browser, Finally...

"C:\Program Files (x86)\Google\Chromium\chrome.exe" --chrome --kiosk http://127.0.0.1/xxxx --incognito --disable-pinch --overscroll-history-navigation=0

exit

Outdated

I use this for exhibitions to lock down screens. I think its what your looking for.

• Start chrome and go to www.google.com drag and drop the url out onto the desktop
• rename it to something handy for this example google_homepage
• drop this now into your c directory, click on my computer c: and drop this file in there
• start chrome again go to settings and under on start up select open a specific page and set your home page here.

Next part is the script that I use to start close and restart chrome again in kiosk mode. The locations is where I have chrome installed so it might be abit different for you depending on your install.

Open your text editor of choice or just notepad and past the below code in, make sure its in the same format/order as below. Save it to your desktop as what ever you like so for this example chrome_startup_script.txt next right click it and rename, remove the txt from the end and put in bat instead. double click this to launch the script to see if its working correctly.

A command line box should appear and run through the script, chrome will start and then close down the reason to do this is to remove any error reports such as if the pc crashed, when chrome starts again without this it would show the yellow error bar at the top saying chrome did not shut down properly would you like to restore it. After a few seconds chrome should start again and in kiosk mode and will point to what ever homepage you have set.

@echo off
echo Step 1 of 5: Waiting a few seconds before starting the Kiosk...
"C:\windows\system32\ping" -n 31 -w 1000 127.0.0.1 >NUL
echo Step 2 of 5: Starting browser as a pre-start to delete error messages...
"C:\google_homepage.url"
echo Step 3 of 5: Waiting a few seconds before killing the browser task...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Step 4 of 5: Killing the browser task gracefully to avoid session restore...
Taskkill /IM chrome.exe
echo Step 5 of 5: Waiting a few seconds before restarting the browser...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Final 'invisible' step: Starting the browser, Finally...
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk --overscroll-history-navigation=0"
exit

Note: The number after the -n of the ping is the amount of seconds (minus one second) to wait before starting the link (or application in the next line)

Finally if this is all working then you can drag and drop the .bat file into the startup folder in windows and this script will launch each time windows starts.

Update:

With recent versions of chrome they have really got into enabling touch gestures, this means that swiping left or right on a touchscreen will cause the browser to go forward or backward in history. To prevent this we need to disable the history navigation on the back and forward buttons to do that add the following --overscroll-history-navigation=0 to the end of the script.

To get a list of the words that appear more than once together with how often they occur, use a combination of GROUP BY and HAVING:

SELECT word, COUNT(*) AS cnt
FROM words
GROUP BY word
HAVING cnt > 1

To find the number of words in the above result set, use that as a subquery and count the rows in an outer query:

SELECT COUNT(*)
FROM
(
    SELECT NULL
    FROM words
    GROUP BY word
    HAVING COUNT(*) > 1
) T1

Yes, in MS SQL Server, you can create scheduled jobs. In SQL Management Studio, navigate to the server, then expand the SQL Server Agent item, and finally the Jobs folder to view, edit, add scheduled jobs.

You can get the coordinate of the target element and set the scroll position to it. But this is so complicated.

Here is a lazier way to do that:

function jump(h){
    var url = location.href;               //Save down the URL without hash.
    location.href = "#"+h;                 //Go to the target element.
    history.replaceState(null,null,url);   //Don't like hashes. Changing it back.
}

This uses replaceState to manipulate the url. If you also want support for IE, then you will have to do it the complicated way:

function jump(h){
    var top = document.getElementById(h).offsetTop; //Getting Y of target element
    window.scrollTo(0, top);                        //Go there directly or some transition
}?

Demo: http://jsfiddle.net/DerekL/rEpPA/
Another one w/ transition: http://jsfiddle.net/DerekL/x3edvp4t/

You can also use .scrollIntoView:

document.getElementById(h).scrollIntoView();   //Even IE6 supports this

_{(Well I lied. It's not complicated at all.)}

I recommend using React.createRef() and ref=this.elementRef to get the DOM element reference instead of ReactDOM.findDOMNode(this). This way you can get the reference to the DOM element as an instance variable.

import React, { Component } from 'react';
import ReactDOM from 'react-dom';

class MenuItem extends Component {

  constructor(props) {
    super(props);

    this.elementRef = React.createRef();
  }

  handleNVFocus = event => {
      console.log('Focused: ' + this.props.menuItem.caption.toUpperCase());
  }
    
  componentDidMount() {
    this.elementRef.addEventListener('nv-focus', this.handleNVFocus);
  }

  componentWillUnmount() {
    this.elementRef.removeEventListener('nv-focus', this.handleNVFocus);
  }

  render() {
    return (
      <element ref={this.elementRef} />
    )
  }

}

export default MenuItem;

try this.

filename = Path.ChangeExtension(".blah") 

in you Case:

myfile= c:/my documents/my images/cars/a.jpg;
string extension = Path.GetExtension(myffile);
filename = Path.ChangeExtension(myfile,".blah") 

You should look this post too:

http://msdn.microsoft.com/en-us/library/system.io.path.changeextension.aspx

var d = new Date(xiYear, xiMonth, xiDate);
d.setTime( d.getTime() + d.getTimezoneOffset()*60*1000 );

This answer is tailored specifically to the original question, and will not give the answer you necessarily expect. In particular, some people will want to subtract the timezone offset instead of add it. Remember though that the whole point of this solution is to hack javascript's date object for a particular deserialization, not to be correct in all cases.

You could use this one-liner:

data = (data[:75] + '..') if len(data) > 75 else data

In my case the issue resolved on commenting the tomcat dependencies exclusion from spring-boot-starte-web

     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <!-- <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions> -->
    </dependency> 

Try this code:

import android.os.Handler;
...
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        // Do something after 5s = 5000ms
        buttons[inew][jnew].setBackgroundColor(Color.BLACK);
    }
}, 5000);

The keyword global is only useful to change or create global variables in a local context, although creating global variables is seldom considered a good solution.

def bob():
    me = "locally defined"    # Defined only in local context
    print(me)

bob()
print(me)     # Asking for a global variable

The above will give you:

locally defined
Traceback (most recent call last):
  File "file.py", line 9, in <module>
    print(me)
NameError: name 'me' is not defined

While if you use the global statement, the variable will become available "outside" the scope of the function, effectively becoming a global variable.

def bob():
    global me
    me = "locally defined"   # Defined locally but declared as global
    print(me)

bob()
print(me)     # Asking for a global variable

So the above code will give you:

locally defined
locally defined

In addition, due to the nature of python, you could also use global to declare functions, classes or other objects in a local context. Although I would advise against it since it causes nightmares if something goes wrong or needs debugging.

3 steps:

1. Download your custom font on Goole Fonts and down load .css file ex: Download http://fonts.googleapis.com/css?family=Open+Sans:400italic,600italic,400,600,300 and save as example.css
2. Open file you download (example.css). Now you must download all font-face file and save them on fonts directory.
3. Edit example.css: replace all font-face file to your .css download

Ex:

@font-face {_x000D_
  font-family: 'Open Sans';_x000D_
  font-style: italic;_x000D_
  font-weight: 400;_x000D_
  src: local('Open Sans Italic'), local('OpenSans-Italic'), url(http://fonts.gstatic.com/s/opensans/v14/xjAJXh38I15wypJXxuGMBvZraR2Tg8w2lzm7kLNL0-w.woff2) format('woff2');_x000D_
  unicode-range: U+0460-052F, U+20B4, U+2DE0-2DFF, U+A640-A69F;_x000D_
}

Look at src: -> url. Download http://fonts.gstatic.com/s/opensans/v14/xjAJXh38I15wypJXxuGMBvZraR2Tg8w2lzm7kLNL0-w.woff2 and save to fonts directory. After that change url to all your downloaded file. Now it will be look like

@font-face {_x000D_
  font-family: 'Open Sans';_x000D_
  font-style: italic;_x000D_
  font-weight: 400;_x000D_
  src: local('Open Sans Italic'), local('OpenSans-Italic'), url(fonts/xjAJXh38I15wypJXxuGMBvZraR2Tg8w2lzm7kLNL0-w.woff2) format('woff2');_x000D_
  unicode-range: U+0460-052F, U+20B4, U+2DE0-2DFF, U+A640-A69F;_x000D_
}

** Download all fonts contain .css file Hope it will help u

As a reference:

def toBinary(n):
    return ''.join(str(1 & int(n) >> i) for i in range(64)[::-1])

This function can convert a positive integer as large as 18446744073709551615, represented as string '1111111111111111111111111111111111111111111111111111111111111111'.

It can be modified to serve a much larger integer, though it may not be as handy as "{0:b}".format() or bin().

I had the exact same problem and it was driving me crazy (Windows 10 and VS Code 1.49.1)

Other answers talk about installing Selenium, but it's clear to me that you've already did that, but you still get the ImportError: No module named 'selenium'.

So, what's going on?

Two things:

1. You installed Selenium in this folder /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg
2. But you're probably running a version of Python, in which you didn't install Selenium. For instance: /Library/Python/3.8/site-packages... you won't find Selenium installed here and that's why the module isn't found.

The solution? You have to install selenium in the same directory to the Python version you're using or change the interpreter to match the directory where Selenium is installed.

In VS Code you change the interpreter here (at the bottom left corner of the screen)

Ready! Now your Python interpreter should find the module.

from django.contrib import admin

urlpatterns = [

When running this command:

ALTER TABLE MYTABLENAME MODIFY CONSTRAINT MYCONSTRAINTNAME_FK ENABLE;

I got this error:

ORA-02270: no matching unique or primary key for this column-list
02270. 00000 -  "no matching unique or primary key for this column-list"
*Cause:    A REFERENCES clause in a CREATE/ALTER TABLE statement
          gives a column-list for which there is no matching unique or primary
          key constraint in the referenced table.
*Action:   Find the correct column names using the ALL_CONS_COLUMNS

The referenced table has a primary key constraint with matching type. The root cause of this error, in my case, was that the primary key constraint was disabled.

// iterate through key-value gracefully
const obj = { a: 5, b: 7, c: 9 };
for (const [key, value] of Object.entries(obj)) {
  console.log(`${key} ${value}`); // "a 5", "b 7", "c 9"
}

Refer MDN

The IFRAME element may be a security risk if your site is embedded inside an IFRAME on hostile site. Google "clickjacking" for more details. Note that it does not matter if you use <iframe> or not. The only real protection from this attack is to add HTTP header X-Frame-Options: DENY and hope that the browser knows its job.

In addition, IFRAME element may be a security risk if any page on your site contains an XSS vulnerability which can be exploited. In that case the attacker can expand the XSS attack to any page within the same domain that can be persuaded to load within an <iframe> on the page with XSS vulnerability. This is because content from the same origin (same domain) is allowed to access the parent content DOM (practically execute JavaScript in the "host" document). The only real protection methods from this attack is to add HTTP header X-Frame-Options: DENY and/or always correctly encode all user submitted data (that is, never have an XSS vulnerability on your site - easier said than done).

That's the technical side of the issue. In addition, there's the issue of user interface. If you teach your users to trust that URL bar is supposed to not change when they click links (e.g. your site uses a big iframe with all the actual content), then the users will not notice anything in the future either in case of actual security vulnerability. For example, you could have an XSS vulnerability within your site that allows the attacker to load content from hostile source within your iframe. Nobody could tell the difference because the URL bar still looks identical to previous behavior (never changes) and the content "looks" valid even though it's from hostile domain requesting user credentials.

If somebody claims that using an <iframe> element on your site is dangerous and causes a security risk, he does not understand what <iframe> element does, or he is speaking about possibility of <iframe> related vulnerabilities in browsers. Security of <iframe src="..."> tag is equal to <img src="..." or <a href="..."> as long there are no vulnerabilities in the browser. And if there's a suitable vulnerability, it might be possible to trigger it even without using <iframe>, <img> or <a> element, so it's not worth considering for this issue.

However, be warned that content from <iframe> can initiate top level navigation by default. That is, content within the <iframe> is allowed to automatically open a link over current page location (the new location will be visible in the address bar). The only way to avoid that is to add sandbox attribute without value allow-top-navigation. For example, <iframe sandbox="allow-forms allow-scripts" ...>. Unfortunately, sandbox also disables all plugins, always. For example, Youtube content cannot be sandboxed because Flash player is still required to view all Youtube content. No browser supports using plugins and disallowing top level navigation at the same time.

Note that X-Frame-Options: DENY also protects from rendering performance side-channel attack that can read content cross-origin (also known as "Pixel perfect Timing Attacks").

Empty array for empty collections and null for everything else.

Don't use MD5 as it is insecure. I would recommend using SHA or bcrypt with a salt:

SHA256('".$password."')

http://en.wikipedia.org/wiki/Salt_(cryptography)

& is a character; & is a HTML character entity for that character.

<br> is an element. Elements don't get character entities.

In contrast to many answers here, \n or 
 are not equivalent to <br>. The former denotes a line break in text documents. The latter is intended to denote a line break in HTML documents and is doing that by virtue of its default CSS:

br:before { content: "\A"; white-space: pre-line }

A textual line break can be rendered as an HTML line break or can be treated as whitespace, depending on the CSS white-space property.

Question is good, but the answer is : it depends on that.

If the other webpage doesn't contain any form or text, for example you can use the CURL method to pickup the exact content and after then showing on your page. YOu can do it without using an iframe.

But, if the page what you want to embed contains for example a form it will not work correctly , because the form handling is on that site.

This should work for MVC3 & MVC4

 @Html.TextBoxFor(m => m.Age, new { @Value = "12" }) 

If you want it to be a hidden field

 @Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" }) 

cell.Text = "your firstline<br style=\"mso-data-placement:same-cell;\">your secondline";

If you are getting the text from DB then:

cell.Text = textfromDB.Replace("\n", "<br style=\"mso-data-placement:same-cell;\">");

Use fgets and strtol,

A pointer to the first character following the integer representation in s is stored in the object pointed by p, if *p is different to \n then you have a bad input.

#include <stdio.h>
#include <stdlib.h>

int main(void) 
{
    char *p, s[100];
    long n;

    while (fgets(s, sizeof(s), stdin)) {
        n = strtol(s, &p, 10);
        if (p == s || *p != '\n') {
            printf("Please enter an integer: ");
        } else break;
    }
    printf("You entered: %ld\n", n);
    return 0;
}

You'll want to listen for escape's keyCode (27) from the React SyntheticKeyBoardEvent onKeyDown:

const EscapeListen = React.createClass({
  handleKeyDown: function(e) {
    if (e.keyCode === 27) {
      console.log('You pressed the escape key!')
    }
  },

  render: function() {
    return (
      <input type='text'
             onKeyDown={this.handleKeyDown} />
    )
  }
})

Brad Colthurst's CodePen posted in the question's comments is helpful for finding key codes for other keys.

fstreams are not slower than C streams, per se, but they use more CPU (especially if buffering is not properly configured). When a CPU saturates, it limits the I/O rate.

At least the MSVC 2015 implementation copies 1 char at a time to the output buffer when a stream buffer is not set (see streambuf::xsputn). So make sure to set a stream buffer (>0).

I can get a write speed of 1500MB/s (the full speed of my M.2 SSD) with fstream using this code:

#include <iostream>
#include <fstream>
#include <chrono>
#include <memory>

I tried this code on other platforms (Ubuntu, FreeBSD) and noticed no I/O rate differences, but a CPU usage difference of about 8:1 (fstream used 8 times more CPU). So one can imagine, had I a faster disk, the fstream write would slow down sooner than the stdio version.

$mail -> CharSet = "UTF-8";
$mail = new PHPMailer();

line $mail -> CharSet = "UTF-8"; must be after $mail = new PHPMailer(); and with no spaces!

try this

$mail = new PHPMailer();
$mail->CharSet = "UTF-8";

I have expanded the solution and combined it with another that I found to replace/update/remove the querystring parameters based on the users input and taking the urls anchor into consideration.

Not supplying a value will remove the parameter, supplying one will add/update the parameter. If no URL is supplied, it will be grabbed from window.location

function UpdateQueryString(key, value, url) {
    if (!url) url = window.location.href;
    var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi"),
        hash;

    if (re.test(url)) {
        if (typeof value !== 'undefined' && value !== null) {
            return url.replace(re, '$1' + key + "=" + value + '$2$3');
        } 
        else {
            hash = url.split('#');
            url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            return url;
        }
    }
    else {
        if (typeof value !== 'undefined' && value !== null) {
            var separator = url.indexOf('?') !== -1 ? '&' : '?';
            hash = url.split('#');
            url = hash[0] + separator + key + '=' + value;
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            return url;
        }
        else {
            return url;
        }
    }
}

Update

There was a bug when removing the first parameter in the querystring, I have reworked the regex and test to include a fix.

Second Update

As suggested by @JarónBarends - Tweak value check to check against undefined and null to allow setting 0 values

Third Update

There was a bug where removing a querystring variable directly before a hashtag would lose the hashtag symbol which has been fixed

Fourth Update

Thanks @rooby for pointing out a regex optimization in the first RegExp object. Set initial regex to ([?&]) due to issue with using (\?|&) found by @YonatanKarni

Fifth Update

Removing declaring hash var in if/else statement

I recommend using the middle index, as it can be calculated easily.

You can calculate it by rounding (array.length / 2).

Just in case someone is having trouble where they have blank spaces either in the date values or in cells, you will have to handle those bits. Sometimes an empty space is not handled by trim function coming from html it's like "$nbsp;". If you don't handle these, your sorting will not work properly and will break where ever there is a blank space.

I got this bit of code from jquery extensions here too and changed it a little bit to suit my requirement. You should do the same:) cheers!

function trim(str) {
    str = str.replace(/^\s+/, '');
    for (var i = str.length - 1; i >= 0; i--) {
        if (/\S/.test(str.charAt(i))) {
            str = str.substring(0, i + 1);
            break;
        }
    }
    return str;
}

Even though the question is too old, but I would like to share the solution that worked for me because I already checked everything when it comes to this error. It was a pain, I spent two days trying and at the end the solution was:

update the M2e plugin in eclipse

clean and build again

Some extra information about .NET Core (after reading erdomke's post about setting a private field to supply the content-type on a request that doesn't have content)...

After debugging my code, I can't see the private field to set via reflection - so I thought I'd try to recreate the problem.

I have tried the following code using .Net 4.6:

HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Get, @"myUrl");
httpRequest.Content = new StringContent(string.Empty, Encoding.UTF8, "application/json");

HttpClient client = new HttpClient();
Task<HttpResponseMessage> response =  client.SendAsync(httpRequest);  //I know I should have used async/await here!
var result = response.Result;

And, as expected, I get an aggregate exception with the content "Cannot send a content-body with this verb-type."

However, if i do the same thing with .NET Core (1.1) - I don't get an exception. My request was quite happily answered by my server application, and the content-type was picked up.

I was pleasantly surprised about that, and I hope it helps someone!

One of the best well-documented example I found.

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

I have written this article about the ICommand interface.

The idea - creating a universal command that takes two delegates: one is called when ICommand.Execute (object param) is invoked, the second checks the status of whether you can execute the command (ICommand.CanExecute (object param)).

Requires the method to switching event CanExecuteChanged. It is called from the user interface elements for switching the state CanExecute() command.

public class ModelCommand : ICommand
{
    #region Constructors

    public ModelCommand(Action<object> execute)
        : this(execute, null) { }

    public ModelCommand(Action<object> execute, Predicate<object> canExecute)
    {
        _execute = execute;
        _canExecute = canExecute;
    }

    #endregion

    #region ICommand Members

    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        return _canExecute != null ? _canExecute(parameter) : true;
    }

    public void Execute(object parameter)
    {
        if (_execute != null)
            _execute(parameter);
    }

    public void OnCanExecuteChanged()
    {
        CanExecuteChanged(this, EventArgs.Empty);
    }

    #endregion

    private readonly Action<object> _execute = null;
    private readonly Predicate<object> _canExecute = null;
}

Below code(jQuery.isEmptyObject(anyObject) function is already provided) works perfectly fine, no need to write one of your own.

   // works for any Object Including JSON(key value pair) or Array.
  //  var arr = [];
  //  var jsonObj = {};
    if (jQuery.isEmptyObject(anyObjectIncludingJSON))
    {
       console.log("Empty Object");
    }

I'm not a java expert but I solve your problem like this:

@FunctionalInterface
public interface AutoCompleteCallable<T> {
  String call(T model) throws Exception;
}

I define the parameter in my special Interface

public <T> void initialize(List<T> entries, AutoCompleteCallable getSearchText) {.......
//call here
String value = getSearchText.call(item);
...
}

Finally, I implement getSearchText method while calling initialize method.

initialize(getMessageContactModelList(), new AutoCompleteCallable() {
          @Override
          public String call(Object model) throws Exception {
            return "custom string" + ((xxxModel)model.getTitle());
          }
        })

You can also try

db.Courses.Include("Modules.Chapters").Single(c => c.Id == id);

For AWS importing an existing public key,

1. Export from the .pem doing this... (on linux)

   openssl rsa -in ./AWSGeneratedKey.pem -pubout -out PublicKey.pub
   

This will produce a file which if you open in a text editor looking something like this...

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAn/8y3uYCQxSXZ58OYceG

PPgWq78db+gU3QsePeo2Ki5sonkcyQQQlCkL35Asbv8khvk90gist4kijPnVBCuv
cwIDAQAB
-----END PUBLIC KEY-----

2. However AWS will NOT accept this file.

   You have to strip off the -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY----- from the file. Save it and import and it should work in AWS.

Every time I've wanted a sleep in the middle of my function, I refactored to use a setTimeout().

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

After insuring that the string "strOutput" has a correct XML structure, you can do this:

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");

You can convert it to datetime, and then use DATEADD(DAY, -30, date).

See here.

edit

I suspect many people are finding this question because they want to substract from current date (as is the title of the question, but not what OP intended). The comment of munyul below answers that question more specifically. Since comments are considered ethereal (may be deleted at any given point), I'll repeat it here:

DATEADD(DAY, -30, GETDATE())

Here's one approach that uses a keylistener,but uses the keyChar (instead of the keyCode):

http://edenti.deis.unibo.it/utils/Java-tips/Validating%20numerical%20input%20in%20a%20JTextField.txt

 keyText.addKeyListener(new KeyAdapter() {
    public void keyTyped(KeyEvent e) {
      char c = e.getKeyChar();
      if (!((c >= '0') && (c <= '9') ||
         (c == KeyEvent.VK_BACK_SPACE) ||
         (c == KeyEvent.VK_DELETE))) {
        getToolkit().beep();
        e.consume();
      }
    }
  });

Another approach (which personally I find almost as over-complicated as Swing's JTree model) is to use Formatted Text Fields:

http://docs.oracle.com/javase/tutorial/uiswing/components/formattedtextfield.html

You can start with a blank tuple with something like t = (). You can add with +, but you have to add another tuple. If you want to add a single element, make it a singleton: t = t + (element,). You can add a tuple of multiple elements with or without that trailing comma.

>>> t = ()
>>> t = t + (1,)
>>> t
(1,)
>>> t = t + (2,)
>>> t
(1, 2)
>>> t = t + (3, 4, 5)
>>> t
(1, 2, 3, 4, 5)
>>> t = t + (6, 7, 8,)
>>> t
(1, 2, 3, 4, 5, 6, 7, 8)

Sending the same cookie value with ; expires appended will not destroy the cookie.

Invalidate the cookie by setting an empty value and include an expires field as well:

Set-Cookie: token=deleted; path=/; expires=Thu, 01 Jan 1970 00:00:00 GMT

Note that you cannot force all browsers to delete a cookie. The client can configure the browser in such a way that the cookie persists, even if it's expired. Setting the value as described above would solve this problem.

I've used Geocoder, a good Python library that supports multiple providers, including Google, Geonames, and OpenStreetMaps, to mention just a few. I've tried using the GeoPy library, and it often gets timeouts. Developing your own code for GeoNames is not the best use of your time and you may end up getting unstable code. Geocoder is very simple to use in my experience, and has good enough documentation. Below is some sample code for looking up city by latitude and longitude, or finding latitude/longitude by city name.

import geocoder

g = geocoder.osm([53.5343609, -113.5065084], method='reverse')
print g.json['city'] # Prints Edmonton

g = geocoder.osm('Edmonton, Canada')
print g.json['lat'], g.json['lng'] # Prints 53.5343609, -113.5065084

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

The object stored at d[a] has not been set to anything. Thus, d[a] evaluates to undefined. You can't assign a property to undefined :). You need to assign an object or array to d[a]:

d[a] = [];
d[a]["greeting"] = b;

In order to receive actual data stored in the table, you should use one of fetch...() functions or use the cursor as an iterator (i.e. "for row in cursor"...). This is described in the documentation:

cursor.execute("select user_id, user_name from users where user_id < 100")
rows = cursor.fetchall()
for row in rows:
    print row.user_id, row.user_name

Attach the function to the onchange method of the input type file /onchange="validateimg(this)"/

   function validateimg(ctrl) { 
        var fileUpload = ctrl;
        var regex = new RegExp("([a-zA-Z0-9\s_\\.\-:])+(.jpg|.png|.gif)$");
        if (regex.test(fileUpload.value.toLowerCase())) {
            if (typeof (fileUpload.files) != "undefined") {
                var reader = new FileReader();
                reader.readAsDataURL(fileUpload.files[0]);
                reader.onload = function (e) {
                    var image = new Image();
                    image.src = e.target.result;
                    image.onload = function () {
                        var height = this.height;
                        var width = this.width;
                        if (height < 1100 || width < 750) {
                            alert("At least you can upload a 1100*750 photo size.");
                            return false;
                        }else{
                            alert("Uploaded image has valid Height and Width.");
                            return true;
                        }
                    };
                }
            } else {
                alert("This browser does not support HTML5.");
                return false;
            }
        } else {
            alert("Please select a valid Image file.");
            return false;
        }
    }

To bring the existing answers together with an important clarification:

As stated, the problem with NAME=sam echo "$NAME" is that $NAME gets expanded by the current shell before assignment NAME=sam takes effect.

Solutions that preserve the original semantics (of the (ineffective) solution attempt NAME=sam echo "$NAME"):

Use either eval^[1] (as in the question itself), or printenv (as added by Aaron McDaid to heemayl's answer), or bash -c (from Ljm Dullaart's answer), in descending order of efficiency:

NAME=sam eval 'echo "$NAME"'  # use `eval` only if you fully control the command string
NAME=sam printenv NAME
NAME=sam bash -c 'echo "$NAME"'

^{printenv is not a POSIX utility, but it is available on both Linux and macOS/BSD.}

What this style of invocation (<var>=<name> cmd ...) does is to define NAME:

• as an environment variable
• that is only defined for the command being invoked.

In other words: NAME only exists for the command being invoked, and has no effect on the current shell (if no variable named NAME existed before, there will be none after; a preexisting NAME variable remains unchanged).

POSIX defines the rules for this kind of invocation in its Command Search and Execution chapter.

The following solutions work very differently (from heemayl's answer):

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

While they produce the same output, they instead define:

• a shell variable NAME (only) rather than an environment variable
  • if echo were a command that relied on environment variable NAME, it wouldn't be defined (or potentially defined differently from earlier).
• that lives on after the command.

Note that every environment variable is also exposed as a shell variable, but the inverse is not true: shell variables are only visible to the current shell and its subshells, but not to child processes, such as external utilities and (non-sourced) scripts (unless they're marked as environment variables with export or declare -x).

^{[1] Technically, bash is in violation of POSIX here (as is zsh): Since eval is a special shell built-in, the preceding NAME=sam assignment should cause the the variable $NAME to remain in scope after the command finishes, but that's not what happens.
However, when you run bash in POSIX compatibility mode, it is compliant.
dash and ksh are always compliant.
The exact rules are complicated, and some aspects are left up to the implementations to decide; again, see Command Search and Execution.
Also, the usual disclaimer applies: Use eval only on input you fully control or implicitly trust.}

No, how you are doing it is correct.

I chopped all my hair off with that issue. I couldn't make the examples above working, so I ended like :

function foo(blabla){
    var func = new Function(blabla);
    func();
}
// to call it, I just pass the js function I wanted as a string in the new one...
foo("alert('test')");

And that's working like a charm ... for what I needed at least. Hope it might help some.

find . -mindepth 1 -maxdepth 1 -type d -printf "%P\n"

You can find the commit id related to each commit in the commits section of GitHub/BitBucket/Gitlab. Its very simple, suppose your commit id is 5889575 then if you want to go back to this part in your code then you simply need to type

git checkout 5889575 .

This will take you to that point of time in your code.

Just adding this for multiple filters attaching to Q object, if someone might be looking to it. If a Q object is provided, it must precede the definition of any keyword arguments. Otherwise its an invalid query. You should be careful when doing it.

an example would be

from django.db.models import Q
User.objects.filter(Q(income__gte=5000) | Q(income__isnull=True),category='income')

Here the OR condition and a filter with category of income is taken into account

public function getLastMonth() {
    $now = new DateTime();
    $lastMonth = $now->sub(new DateInterval('P1M'));
    return $lastMonth->format('Ym');
}

try to show popup like this

new Handler().postDelayed(new Runnable(){

    public void run() {
       popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);
    }

}, 200L);

SELECT *
FROM tbl_name
WHERE coalesce(id_field,'unik_null_value') 
IN ('value1', 'value2', 'value3', 'unik_null_value')

So that you eliminate the null from the check. Given a null value in id_field, the coalesce function would instead of null return 'unik_null_value', and by adding 'unik_null_value to the IN-list, the query would return posts where id_field is value1-3 or null.

Here is a short solution.

$handle = curl_init($uri);
curl_setopt($handle,  CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($handle,CURLOPT_HTTPHEADER,array ("Accept: application/rdf+xml"));
curl_setopt($handle, CURLOPT_NOBODY, true);
curl_exec($handle);
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
if($httpCode == 200||$httpCode == 303) 
{
    echo "you might get a reply";
}
curl_close($handle);

In your case, you can change application/rdf+xml to whatever you use.

A very convenient way is readr::read_delim-family. Taking the example from here: Importing csv with multiple separators into R you can do it as follows:

txt <- 'OBJECTID,District_N,ZONE_CODE,COUNT,AREA,SUM
1,Bagamoyo,1,"136,227","8,514,187,500.000000000000000","352,678.813105723350000"
2,Bariadi,2,"88,350","5,521,875,000.000000000000000","526,307.288878142830000"
3,Chunya,3,"483,059","30,191,187,500.000000000000000","352,444.699742995200000"'

require(readr)
read_csv(txt) # = read_delim(txt, delim = ",")

Which results in the expected result:

# A tibble: 3 × 6
  OBJECTID District_N ZONE_CODE  COUNT        AREA      SUM
     <int>      <chr>     <int>  <dbl>       <dbl>    <dbl>
1        1   Bagamoyo         1 136227  8514187500 352678.8
2        2    Bariadi         2  88350  5521875000 526307.3
3        3     Chunya         3 483059 30191187500 352444.7

Example: Read json from file

/* test.json */
{
   "appDesc": {
      "description": "SomeDescription",
      "message": "SomeMessage"
   },
   "appName": {
      "description": "Home",
      "message": "Welcome",
      "imp":["awesome","best","good"]
   }
}


void readJson()
   {
      QString val;
      QFile file;
      file.setFileName("test.json");
      file.open(QIODevice::ReadOnly | QIODevice::Text);
      val = file.readAll();
      file.close();
      qWarning() << val;
      QJsonDocument d = QJsonDocument::fromJson(val.toUtf8());
      QJsonObject sett2 = d.object();
      QJsonValue value = sett2.value(QString("appName"));
      qWarning() << value;
      QJsonObject item = value.toObject();
      qWarning() << tr("QJsonObject of description: ") << item;

      /* in case of string value get value and convert into string*/
      qWarning() << tr("QJsonObject[appName] of description: ") << item["description"];
      QJsonValue subobj = item["description"];
      qWarning() << subobj.toString();

      /* in case of array get array and convert into string*/
      qWarning() << tr("QJsonObject[appName] of value: ") << item["imp"];
      QJsonArray test = item["imp"].toArray();
      qWarning() << test[1].toString();
   }

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

Example: Read json from string

Assign json to string as below and use the readJson() function shown before:

val =   
'  {
       "appDesc": {
          "description": "SomeDescription",
          "message": "SomeMessage"
       },
       "appName": {
          "description": "Home",
          "message": "Welcome",
          "imp":["awesome","best","good"]
       }
    }';

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

In Ubuntu you can apply this way,

to save file at some location (temporary) and then open and send it to API

      path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
      path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
      data={} #can be anything u want to pass along with File
      file1 = open(path12, 'rb')
      header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
       res= requests.post(url,data,header)

I just discovered that LNK2019 occurs during compilation in Visual Studio 2015 if forgetting to provide a definition for a declared function inside a class.

The linker error was highly cryptic, but I narrowed it down to what was missing by reading through the error and provided the definition outside the class to clear this up.

If you define

    #!/bin/bash
        fun1(){
          echo "Fun1 from file1 $1"
        }
fun1 Hello
. file2 
fun1 Hello
exit 0

in file1(chmod 750 file1) and file2

   fun1(){
      echo "Fun1 from file2 $1"
    }
    fun2(){
      echo "Fun1 from file1 $1"
    }

and run ./file2 you'll get Fun1 from file1 Hello Fun1 from file2 Hello Surprise!!! You overwrite fun1 in file1 with fun1 from file2... So as not to do so you must

declare -f pr_fun1=$fun1
. file2
unset -f fun1
fun1=$pr_fun1
unset -f pr_fun1
fun1 Hello

it's save your previous definition for fun1 and restore it with the previous name deleting not needed imported one. Every time you import functions from another file you may remember two aspects:

1. you may overwrite existing ones with the same names(if that the thing you want you must preserve them as described above)
2. import all content of import file(functions and global variables too) Be careful! It's dangerous procedure

I would just do

var list = new List<string> { "hello" };

• cd /usr/local
• git status
• Discard all the changes (unless you actually want to try to commit to Homebrew - you probably don't)
• git status til it's clean
• brew update

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

My which pip shows the following path:

$ which pip
/home/kmario23/anaconda3/bin/pip

So, whatever package I install using pip install <package-name> will have to be reflected in the list of packages when the list is exported using:

$ conda list --export > conda_list.txt

But, I don't. So, instead I used the following command as suggested by several others:

# get environment name by
$ conda-env list

# get list of all installed packages by (conda, pip, etc.,)
$ conda-env export -n <my-environment-name> > all_packages.yml
# if you haven't created any specific env, then just use 'root'

Now, I can see all the packages in my all-packages.yml file.

The only solution that worked for me and $.each was definitely causing the error. so i used for loop and it's not throwing error anymore.

Example code

     $.ajax({
            type: 'GET',
            url: 'https://example.com/api',
            data: { get_param: 'value' },
            success: function (data) {
                for (var i = 0; i < data.length; ++i) {
                    console.log(data[i].NameGerman);
                }
            }
        });

There is an alternative to repeating the CONCAT expression or using subqueries. You can make use of the HAVING clause, which recognizes column aliases.

SELECT 
  neededfield, CONCAT(firstname, ' ', lastname) AS firstlast 
FROM
  users 
HAVING firstlast = "Bob Michael Jones"

Here is a working SQL Fiddle.

If you want to add a single unit of time and you expect that other fields to be incremented as well, you can safely use add method. See example below:

SimpleDateFormat simpleDateFormat1 = new SimpleDateFormat("yyyy-MM-dd");
Calendar cal = Calendar.getInstance();
cal.set(1970,Calendar.DECEMBER,31);
System.out.println(simpleDateFormat1.format(cal.getTime()));
cal.add(Calendar.DATE, 1);
System.out.println(simpleDateFormat1.format(cal.getTime()));
cal.add(Calendar.DATE, -1);
System.out.println(simpleDateFormat1.format(cal.getTime()));

Will Print:

1970-12-31
1971-01-01
1970-12-31

This is a common problem with people getting started. Whenever you update your UI elements from a thread other than the main thread, you need to use:

this.Dispatcher.Invoke(() =>
{
    ...// your code here.
});

You can also use control.Dispatcher.CheckAccess() to check whether the current thread owns the control. If it does own it, your code looks as normal. Otherwise, use above pattern.

If you are using the SQL Expression Style approach there is another way to construct the count statement if you already have your table object.

Preparations to get the table object. There are also different ways.

import sqlalchemy

database_engine = sqlalchemy.create_engine("connection string")

# Populate existing database via reflection into sqlalchemy objects
database_metadata = sqlalchemy.MetaData()
database_metadata.reflect(bind=database_engine)

table_object = database_metadata.tables.get("table_name") # This is just for illustration how to get the table_object                    

Issuing the count query on the table_object

query = table_object.count()
# This will produce something like, where id is a primary key column in "table_name" automatically selected by sqlalchemy
# 'SELECT count(table_name.id) AS tbl_row_count FROM table_name'

count_result = database_engine.scalar(query)

try adjusting the order in which your script runs. Place the script tag below the element it is trying to affect. Or leave it up at the top and wrap it in a $(document).ready() EDIT: and include the right file.

Remark: not too easy way, but workable and it has its own unique pros.

If one want to clone only HEAD revision of a repository and only HEADs of all the its submodules (i.e. to checkout "trunk"), then one can use following Lua script. Sometimes simple command git submodule update --init --recursive --remote --no-fetch --depth=1 can result in an unrecoverable git error. In this case one need to clean up subdirectory of .git/modules directory and clone submodule manually using git clone --separate-git-dir command. The only complexity is to find out URL, path of .git directory of submodule and path of submodule in superproject tree.

Remark: the script is only tested against https://github.com/boostorg/boost.git repository. Its peculiarities: all the submodules hosted on the same host and .gitmodules contains only relative URLs.

-- mkdir boost ; cd boost ; lua ../git-submodules-clone-HEAD.lua https://github.com/boostorg/boost.git .
local module_url = arg[1] or 'https://github.com/boostorg/boost.git'
local module = arg[2] or module_url:match('.+/([_%d%a]+)%.git')
local branch = arg[3] or 'master'
function execute(command)
    print('# ' .. command)
    return os.execute(command)
end
-- execute('rm -rf ' .. module)
if not execute('git clone --single-branch --branch master --depth=1 ' .. module_url .. ' ' .. module) then
    io.stderr:write('can\'t clone repository from ' .. module_url .. ' to ' .. module .. '\n')
    return 1
end
-- cd $module ; git submodule update --init --recursive --remote --no-fetch --depth=1
execute('mkdir -p ' .. module .. '/.git/modules')
assert(io.input(module .. '/.gitmodules'))
local lines = {}
for line in io.lines() do
    table.insert(lines, line)
end
local submodule
local path
local submodule_url
for _, line in ipairs(lines) do
    local submodule_ = line:match('^%[submodule %"([_%d%a]-)%"%]$')
    if submodule_ then
        submodule = submodule_
        path = nil
        submodule_url = nil
    else
        local path_ = line:match('^%s*path = (.+)$')
        if path_ then
            path = path_
        else
            submodule_url = line:match('^%s*url = (.+)$')
        end
        if submodule and path and submodule_url then
            -- execute('rm -rf ' .. path)
            local git_dir = module .. '/.git/modules/' .. path:match('^.-/(.+)$')
            -- execute('rm -rf ' .. git_dir)
            execute('mkdir -p $(dirname "' .. git_dir .. '")')
            if not execute('git clone --depth=1 --single-branch --branch=' .. branch .. ' --separate-git-dir ' .. git_dir .. ' ' .. module_url .. '/' .. submodule_url .. ' ' .. module .. '/' .. path) then
                io.stderr:write('can\'t clone submodule ' .. submodule .. '\n')
                return 1
            end
            path = nil
            submodule_url = nil
        end
    end
end

I'm late to the party, but searching for the correct way to do it I came across this page it was one of the top Google search returns, so I will like to share my view on the problem, which I consider it to be up to date at the time of writing this post (beginning of 2017). From PHP 7.1.0 the mcrypt_decrypt and mcrypt_encrypt is going to be deprecated, so building future proof code should use openssl_encrypt and openssl_decrypt

You can do something like:

$string_to_encrypt="Test";
$password="password";
$encrypted_string=openssl_encrypt($string_to_encrypt,"AES-128-ECB",$password);
$decrypted_string=openssl_decrypt($encrypted_string,"AES-128-ECB",$password);

Important: This uses ECB mode, which isn't secure. If you want a simple solution without taking a crash course in cryptography engineering, don't write it yourself, just use a library.

You can use any other chipper methods as well, depending on your security need. To find out the available chipper methods please see the openssl_get_cipher_methods function.

Probably you change configuration file in "httpd-ssl.conf"

<VirtualHost _default_:443>
DocumentRoot "D:/Server/xServer"
ServerName xyz.abc.com
SSLCertificateFile "conf/ssl.crt/xyz.crt"
SSLCertificateKeyFile "conf/ssl.key/sftaps.in.key"
</VirtualHost>

May be you change certificate name or something in Apache folder.

#UBUNTU20

if you are opening this file as root, then type

root# visudo

the file will be opened, go to the line where you want to add/modifiy anything simply without any insert or i button pressed.

press ctrl + O
press ctrl + x
press enter

Java

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

Just a slight addition to the above solution if you are having problem with downloaded file's name...

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.Name + "\"");

This will return the exact file name even if it contains spaces or other characters.

By searching for my userid in the registry, I found

HKEY_CURRENT_USER\Volatile Environment\Username

Reliable, working example that I've been using for years:

function camelize(text) {
    text = text.replace(/[-_\s.]+(.)?/g, (_, c) => c ? c.toUpperCase() : '');
    return text.substr(0, 1).toLowerCase() + text.substr(1);
}

Case-changing characters:

• hyphen -
• underscore _
• period .
• space

I found a workaround that is quite satisfactory. I installed Anaconda Python and this now works out of the box for me.

In simple terms you need to build your payload into a key array

payload = {'key1': 'value1', 'key2': 'value2'}

Then send the payload directly to the action

this.$store.dispatch('yourAction', payload)

No change in your action

yourAction: ({commit}, payload) => {
  commit('YOUR_MUTATION',  payload )
},

In your mutation call the values with the key

'YOUR_MUTATION' (state,  payload ){
  state.state1 = payload.key1
  state.state2 =  payload.key2
},

Each call to nextLine() moves onto the next line, so when you are actually at the last readable line and the while check passes inspection, the next call to nextLine() will return EOF.

Perhaps you could do one of the following instead:

If fileReader is of type Scanner:

while ((line = fileReader.hasNextLine()) != null) {
    String line = fileReader.nextLine(); 
    System.out.println(line);
}

If fileReader is of type BufferedReader:

String line;
while ((line = fileReader.readLine()) != null) {
    System.out.println(line);
}

So you're reading the current line in the while condition and saving the line in a string for later use.

Beginning each new line with two white spaces will avoid the auto-remove perpetrated by Outlook.

var lineString = "  line 1\r\n";
linestring += "  line 2";

Will correctly display:

line 1
line 2

It's a little clumsy feeling to use, but it does the job without a lot of extra effort being spent on it.

You can get what you want using this:

SUBSTR('ABCD1234EFGH',REGEXP_INSTR ('ABCD1234EFGH', '[[:digit:]]'),REGEXP_COUNT ('ABCD1234EFGH', '[[:digit:]]'))

Sample Query:

SELECT SUBSTR('003Preliminary Examination Plan  ',REGEXP_INSTR ('003Preliminary Examination Plan  ', '[[:digit:]]'),REGEXP_COUNT ('003Preliminary Examination Plan  ', '[[:digit:]]')) SAMPLE1,
SUBSTR('Coordination005',REGEXP_INSTR ('Coordination005', '[[:digit:]]'),REGEXP_COUNT ('Coordination005', '[[:digit:]]')) SAMPLE2,
SUBSTR('Balance1000sheet',REGEXP_INSTR ('Balance1000sheet', '[[:digit:]]'),REGEXP_COUNT ('Balance1000sheet', '[[:digit:]]')) SAMPLE3 FROM DUAL

EDIT: This is the answer for inazaruk and electrichead... I had run into a similar issue to them and found out the following...

There is a long-standing bug for this problem here: http://code.google.com/p/android/issues/detail?id=6191

Looks like it started around Android 2.1 and has been present in all of the Android 2.x releases since. I'm not sure if it is still a problem in Android 3.x or 4.x though.

Anyway, this StackOverflow post explains how to workaround the problem correctly (it doesn't look relevant by the URL but I promise it is)

Why does keyboard-slide crash my app?

In Kotlin you can use extension

fun Context.getMyDrawable(id : Int) : Drawable?{

    return  ContextCompat.getDrawable(this, id)
}

then use like

context.getMyDrawable(R.drawable.my_icon)

For MS SQL Server 2012 and above

USE [master];

DECLARE @kill varchar(8000) = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), session_id) + ';'  
FROM sys.dm_exec_sessions
WHERE database_id  = db_id('MyDB')

EXEC(@kill);

For MS SQL Server 2000, 2005, 2008

USE master;

DECLARE @kill varchar(8000); SET @kill = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'  
FROM master..sysprocesses  
WHERE dbid = db_id('MyDB')

EXEC(@kill); 

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

In order to have a popop with Chrome 14+, you need to do the following :

jQuery(window).bind('beforeunload', function(){
    return 'my text';
});

The user will be asked if he want to stay or leave.

The other thing this does is push the function invocation to the bottom of the stack, preventing a stack overflow if you are recursively calling a function. This has the effect of a while loop but lets the JavaScript engine fire other asynchronous timers.

As well as escaping quotes with backslashes, also see SO question 2911073 which explains how you could alternatively use double-quoting in a @-prefixed string:

string msg = @"I want to learn ""c#""";

Just a thought, but just decided to create a counter variable and store the array size in position [0]. I deleted most of the code I had in the function but you'll see after exiting the loop, prime[0] is assigned the final value of 'a'. I tried using vectors but VS Express 2013 didn't like that very much. Also make note that 'a' starts at one to avoid overwriting [0] and it's initialized in the beginning to avoid errors. I'm no expert, just thought I'd share.

int prime[] = {0};
int primes(int x, int y){
    using namespace std; int a = 1;
    for (int i = x; i <= y; i++){prime[a] = i; a++; }
    prime[0] = a; return 0;
}

Try this:

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
     geom_bar(position = 'dodge', stat='identity') +
     geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

With numpy :

im = Image.open('image.gif')
im_matrix = np.array(im)
print(im_matrix[0][0])

Give RGB vector of the pixel in position (0,0)

The problem I had was that although the source data was correctly formatted as 'date' dd/mm/yyyy, the pivot table placed (for example) 22/05/2019 between 16/05/2019 and 17/05/2019. This data was visible in the pivot table, but in the wrong place. In addition, the Pivot chart refused to show that data for that date even though the 'Date' filter allowed it to be selected.

In my case, I had to:

1. From the Pivot Chart,open the 'Date' Filter menu.

2. select the 'Sort Oldest to Newest' option.

3. Bingo! The Pivot chart now shows the missing date data.

run the following command by creating a virtual enviroment using python 3 and run

pip3 install opencv-python

to check it has installed correctly run

python3 -c "import cv2"

Try:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 

<SeekBar 
    android:id="@+id/seekBar1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:rotation="270" 
    /> 

</RelativeLayout> 

You can combine the check and cast into one statement:

let touch = object.anyObject() as UITouch
if let picker = touch.view as? UIPickerView {
    ...
}

Then you can use picker within the if block.

I have a more useful version if you are interested. I lifted a bit of code from here a website where the link is no longer active. I modifyied it to allow for an array of tables into the stored procedure and it populates the drop, truncate, add statements before executing all of them. This gives you control to decide which tables need truncating.

Considering that XML data comes from a table 'table' and is stored in a column 'field': use the XML methods, extract values with xml.value(), project nodes with xml.nodes(), use CROSS APPLY to join:

SELECT 
    p.value('(./firstName)[1]', 'VARCHAR(8000)') AS firstName,
    p.value('(./lastName)[1]', 'VARCHAR(8000)') AS lastName
FROM table 
    CROSS APPLY field.nodes('/person') t(p)

You can ditch the nodes() and cross apply if each field contains exactly one element 'person'. If the XML is a variable you select FROM @variable.nodes(...) and you don't need the cross apply.

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your build.gradle.

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Gradle 1.7+, Android gradle plugin 0.6.+ are required.

Note, that only try with resources require minSdkVersion 19. Other features works on previous platforms.

Use compareTo(BigDecimal.ZERO) instead of equals():

if (price.compareTo(BigDecimal.ZERO) == 0) // see below

Comparing with the BigDecimal constant BigDecimal.ZERO avoids having to construct a new BigDecimal(0) every execution.

FYI, BigDecimal also has constants BigDecimal.ONE and BigDecimal.TEN for your convenience.

Note!

The reason you can't use BigDecimal#equals() is that it takes scale into consideration:

new BigDecimal("0").equals(BigDecimal.ZERO) // true
new BigDecimal("0.00").equals(BigDecimal.ZERO) // false!

so it's unsuitable for a purely numeric comparison. However, BigDecimal.compareTo() doesn't consider scale when comparing:

new BigDecimal("0").compareTo(BigDecimal.ZERO) == 0 // true
new BigDecimal("0.00").compareTo(BigDecimal.ZERO) == 0 // true

The issue with the null connection is related to the findBT() function. you must change the device name from "MattsBlueTooth" to your device name as well as confirm the UUID for your service/device. Use something like BLEScanner app to confrim both on Android.

One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.

For example:

background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.

Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:

background_label.image = background_image

My advice is to use a library. There are several available at pypi.org.

I use this one, it it works good: https://pypi.python.org/pypi/asjson

ul.menu li a:before, ul.menu li .item:before, ul.menu li .separator:before {
  content: "\2022";
  font-family: FontAwesome;
  margin-right: 10px;
  display: inline;
  vertical-align: middle;
  font-size: 1.6em;
  font-weight: normal;
}

Is present in your site's CSS, looks like it's coming from a compiled CSS file from within your application. Perhaps from a plugin. Changing the name of the "menu" class you are using should resolve the issue.

Do not use this return `${ pre }_${ new Date().getTime()}`;. It's better to have the array index instead of that because, even though it's not ideal, that way you will at least get some consistency among the list components, with the new Date function you will get constant inconsistency. That means every new iteration of the function will lead to a new truly unique key.

The unique key doesn't mean that it needs to be globally unique, it means that it needs to be unique in the context of the component, so it doesn't run useless re-renders all the time. You won't feel the problem associated with new Date initially, but you will feel it, for example, if you need to get back to the already rendered list and React starts getting all confused because it doesn't know which component changed and which didn't, resulting in memory leaks, because, you guessed it, according to your Date key, every component changed.

Now to my answer. Let's say you are rendering a list of YouTube videos. Use the video id (arqTu9Ay4Ig) as a unique ID. That way, if that ID doesn't change, the component will stay the same, but if it does, React will recognize that it's a new Video and change it accordingly.

It doesn't have to be that strict, the little more relaxed variant is to use the title, like Erez Hochman already pointed out, or a combination of the attributes of the component (title plus category), so you can tell React to check if they have changed or not.

You might need to convert the decimal to money (or decimal(8,2)) to get that exact formatting. The convert method can take a third parameter that controls the formatting style:

convert(varchar, cast(price as money))       12345.67
convert(varchar, cast(price as money), 0)    12345.67
convert(varchar, cast(price as money), 1)    12,345.67

Here is a quick fix:

All the pros will probably hate me for this answer. But I got the same error on a server: Fatal error: Uncaught Error: Call to undefined function mysql_connect() that was using PHP 7. Did not have time to rewrite all the mysql code so a quick, temporary fix if anyone needs it is in CPANEL to look for PHP Configuration and change the version for that account to something like PHP 5.4 instead of PHP 7. Then the code worked fine without the above error.

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

As others have suggested, you are not clearly explaining your problem, what you are trying to do, or what your expectations are as to what this function is actually supposed to do.

If I have understood correctly, then you are expecting this function to refresh the page for you (you actually use the term "reloads the browser").

But this function is not intended to reload the browser.

All the function does, is to add (push) a new "state" onto the browser history, so that in future, the user will be able to return to this state that the web-page is now in.

Normally, this is used in conjunction with AJAX calls (which refresh only a part of the page).

For example, if a user does a search "CATS" in one of your search boxes, and the results of the search (presumably cute pictures of cats) are loaded back via AJAX, into the lower-right of your page -- then your page state will not be changed. In other words, in the near future, when the user decides that he wants to go back to his search for "CATS", he won't be able to, because the state doesn't exist in his history. He will only be able to click back to your blank search box.

Hence the need for the function

history.pushState({},"Results for `Cats`",'url.html?s=cats');

It is intended as a way to allow the programmer to specifically define his search into the user's history trail. That's all it is intended to do.

When the function is working properly, the only thing you should expect to see, is the address in your browser's address-bar change to whatever you specify in your URL.

If you already understand this, then sorry for this long preamble. But it sounds from the way you pose the question, that you have not.

As an aside, I have also found some contradictions between the way that the function is described in the documentation, and the way it works in reality. I find that it is not a good idea to use blank or empty values as parameters.

See my answer to this SO question. So I would recommend putting a description in your second parameter. From memory, this is the description that the user sees in the drop-down, when he clicks-and-holds his mouse over "back" button.

TL;DR:

• Use random_int() and the given random_str() below.
• If you don't have random_int(), use random_compat.

Explanation:

Since you are generating a password, you need to ensure that the password you generate is unpredictable, and the only way to ensure this property is present in your implementation is to use a cryptographically secure pseudorandom number generator (CSPRNG).

The requirement for a CSPRNG can be relaxed for the general case of random strings, but not when security is involved.

The simple, secure, and correct answer to password generation in PHP is to use RandomLib and don't reinvent the wheel. This library has been audited by industry security experts, as well as myself.

For developers who prefer inventing your own solution, PHP 7.0.0 will provide random_int() for this purpose. If you're still on PHP 5.x, we wrote a PHP 5 polyfill for random_int() so you can use the new API before PHP 7 is released. Using our random_int() polyfill is probably safer than writing your own implementation.

With a secure random integer generator on hand, generating a secure random string is easier than pie:

<?php
/**
 * Generate a random string, using a cryptographically secure 
 * pseudorandom number generator (random_int)
 * 
 * For PHP 7, random_int is a PHP core function
 * For PHP 5.x, depends on https://github.com/paragonie/random_compat
 * 
 * @param int $length      How many characters do we want?
 * @param string $keyspace A string of all possible characters
 *                         to select from
 * @return string
 */
function random_str(
    $length,
    $keyspace = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
) {
    $str = '';
    $max = mb_strlen($keyspace, '8bit') - 1;
    if ($max < 1) {
        throw new Exception('$keyspace must be at least two characters long');
    }
    for ($i = 0; $i < $length; ++$i) {
        $str .= $keyspace[random_int(0, $max)];
    }
    return $str;
}

For those using Altap Salamander (2 panels file manager) : in the Options of the Copy popup, just specify the file names or masks. Easy.

With version 3 of PowerShell you can chain the replace calls together:

 (Get-Content $sourceFile) | ForEach-Object {
    $_.replace('something1', 'something1').replace('somethingElse1', 'somethingElse2')
 } | Set-Content $destinationFile

For the record, I am testing two codes: That simply try to convert from a string to a number and if it fail then assign number to zero.

        if (!Int32.TryParse(txt,out tmpint)) {
            tmpint = 0;
        }

and:

        try {
            tmpint = Convert.ToInt32(txt);
        } catch (Exception) {
            tmpint = 0;
        }

For c#, the best option is to use tryparse because try&Catch alternative thrown the exception

A first chance exception of type 'System.FormatException' occurred in mscorlib.dll

That it is painful slow and undesirable, however, the code does not stop unless Debug's exception are settled for stop with it.

You simply need to do a SUBSTR on the string in col3....

    Select col1, col2, REPLACE(substr(col3, instr(col3, 'Client Name'), 
    (instr(col3, '|', instr(col3, 'Client Name')  -
    instr(col3, 'Client Name'))
    ),
'Client Name = ',
'')
    from Table01 

And yes, that is a bad DB design for the reasons stated in the original issue

Are you committing the cell before pressing the button (pressing Enter)? The contents of the cell must be stored before it can be used to name a sheet.

A better way to do this is to pop up a dialog box and get the name you wish to use.

set value in check box like this :

<input id="responsable" name="checkResp" value="true" type="checkbox" />

change checkResp to nullable property in Your model like this :

public Nullable<bool> checkResp{ get; set; }

use ? before checkResp like :

public ActionResult Index( string responsables, bool ? checkResp)
{
 ......
}

I was looking for a way to mimic the CTRL+Shift+End, so dotNET solution is great, except with my Excel 2010 I need to add a set if I want to avoid an error:

Function GetLastCell(sh As Worksheet) As Range
  Set GetLastCell = sh.Cells(1, 1).SpecialCells(xlLastCell)
End Function

and how to check this for yourself:

Sub test()
  Dim ws As Worksheet, r As Range
  Set ws = ActiveWorkbook.Sheets("Sheet1")
  Set r = GetLastCell(ws)
  MsgBox r.Column & "-" & r.Row
End Sub

For those looking to create custom back buttons as well as have their title removed please use the following piece of code within the view controller that's pushing the new one:

self.navigationController?.navigationBar.backIndicatorImage = UIImage(named: "close")
self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "close")
self.navigationItem?.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)

For a more universal use, do the following:

1. Create a universal function as follows:

   func addCustomizedBackBtn(navigationController: UINavigationController?, navigationItem: UINavigationItem?) {
       navigationController?.navigationBar.backIndicatorImage = UIImage(named: "close")
       navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "close")
       navigationItem?.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
   }
   

2. Then use it in the view controllers as follows:

   addCustomizedBackBtn(navigationController: self.navigationController, navigationItem: self.navigationItem)
   

well the only thing that will work is

python -m pip install pip==

you can and should run it under IDE terminal (mine was pycharm)

If you want to convert a python datetime to seconds since epoch you should do it explicitly:

>>> import datetime
>>> datetime.datetime(2012, 04, 01, 0, 0).strftime('%s')
'1333234800'
>>> (datetime.datetime(2012, 04, 01, 0, 0) - datetime.datetime(1970, 1, 1)).total_seconds()
1333238400.0

In Python 3.3+ you can use timestamp() instead:

>>> import datetime
>>> datetime.datetime(2012, 4, 1, 0, 0).timestamp()
1333234800.0

Here is a little lib to load javascript and CSS files dynamically:

https://github.com/todotresde/javascript-loader

I guess is usefull to load css and js files in order and dynamically.

Support to extend to load any lib you want, and not just the main file, you can use it to load custom files.

I.E.:

<html>
<head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="scripts/javascript-loader.js" type="text/javascript" charset="utf-8" ></script>    
    <script type="text/javascript">
        $(function() {

            registerLib("threejs", test);

            function test(){
                console.log(THREE);
            }

            registerLib("tinymce", draw);

            function draw(){
                tinymce.init({selector:'textarea'});
            }

        }); 
    </script>
</head>
<body>
    <textarea>Your content here.</textarea>
</body>

I think one of the easiest ways to achieve this is to replace "continue" with "break" statement,i.e.

for ii in range(200):
 for jj in range(200, 400):
    ...block0...
    if something:
        break
 ...block1...       

For example, here is the easy code to see how exactly it goes on:

for i in range(10):
    print("doing outer loop")
    print("i=",i)
    for p in range(10):
        print("doing inner loop")
        print("p=",p)
        if p==3:
            print("breaking from inner loop")
            break
    print("doing some code in outer loop")

in case if someone using the codeigniter framework, the problem may be caused by the csrf protection config enabled.

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

For a simple and effective PDF viewer, when you require only limited functionality, you can now (iOS 4.0+) use the QuickLook framework:

First, you need to link against QuickLook.framework and #import <QuickLook/QuickLook.h>;

Afterwards, in either viewDidLoad or any of the lazy initialization methods:

QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];

No, I think you are thinking of stack space. Heap space is occupied by objects. The way to increase it is -Xmx256m, replacing the 256 with the amount you need on the command line.

I set up Visual Studio Code as a default to open .txt file. And next I did use simple command: git config --global core.editor "'C:\Users\UserName\AppData\Local\Code\app-0.7.10\Code.exe\'". And everything works pretty well.

Try using "uname". For example, in Linux: "uname -a".

According to the manual page, uname conforms to SVr4 and POSIX, so it should be available on Mac OS X and Cygwin too, but I can't confirm that.

BTW: $OSTYPE is also set to linux-gnu here :)

Getting the first line is trivially easy. For the last line, presuming you know an approximate upper bound on the line length, os.lseek some amount from SEEK_END find the second to last line ending and then readline() the last line.

I added a mMap.setOnMarkerClickListener(this); in the onMapReady(GoogleMap googleMap) method. So every time you click a marker it displays the text name in the toast method.

public class DemoMapActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener,OnMapReadyCallback, GoogleMap.OnMarkerClickListener {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_places);
    Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    double lat=0.34924212701428;
    double lng=32.616554024713;
    String venue = "Capital Shoppers City";
    LatLng location = new LatLng(lat, lng);
    mMap.addMarker(new MarkerOptions().position(location).title(venue)).setTag(0);
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLng(location);
    CameraUpdate zoom = CameraUpdateFactory.zoomTo(16);
    mMap.moveCamera(cameraUpdate);
    mMap.animateCamera(zoom);
    mMap.setOnMarkerClickListener(this);
}

@Override
public boolean onMarkerClick(final Marker marker) {
    // Retrieve the data from the marker.
    Integer clickCount = (Integer) marker.getTag();

    // Check if a click count was set, then display the click count.
    if (clickCount != null) {
        clickCount = clickCount + 1;
        marker.setTag(clickCount);
        Toast.makeText(this,
                       marker.getTitle() +
                       " has been clicked ",
                       Toast.LENGTH_SHORT).show();
    }
    // Return false to indicate that we have not consumed the event and that we wish
    // for the default behavior to occur (which is for the camera to move such that the
    // marker is centered and for the marker's info window to open, if it has one).
    return false;
}

}

After spending some time on the issue, trying solutions that didn't work, I run into this blog. It suggests to wrap the service initialization code in a try/catch block, like this, and adding EventLog

using System;
using System.Diagnostics;
using System.ServiceProcess;

namespace WindowsService
{
    static class Program
    {
        static void Main()
        {
            try
            {
                ServiceBase[] ServicesToRun;
                ServicesToRun = new ServiceBase[] 
                { 
                    new Service1() 
                };
                ServiceBase.Run(ServicesToRun);
            }
            catch (Exception ex)
            {
                EventLog.WriteEntry("Application", ex.ToString(), EventLogEntryType.Error);
            }
        }
    }
}

Then, uninstall the old service, redeploy the service with these modifications. Start the service and check out the Event Viewer/Application logs. You'll see what the real problem is, which is the underlying reason for the timeout.

It's difficult to tell what you're actually trying to do and if this is what you really need but you might also use a callback:

function myFunction(value1,callback)
{
     //Do stuff and 

     if(typeof callback == 'function'){
        callback(somevalue2,somevalue3);
    }
}


myFunction("1", function(value2, value3){
    if(value2 && value3)
    {
    //Do some stuff
    }
});

If you want to stick with Jquery's .load() method, add something unique to the URL like a JavaScript timestamp. "+new Date().getTime()". Notice I had to add an "&time=" so it does not alter your pid variable.

$('#searchButton').click(function() {
$('#inquiry').load('/portal/?f=searchBilling&pid=' + $('#query').val()+'&time='+new Date().getTime());            
});

First set in the following path Tools->Options->Text Editor->All Languages->Tabs if still didn't work modify as mentioned below Go to Edit->Advanced->Set Indentation ->Spaces

 #header {
        top:0;
        width:100%;
        position:fixed;
        background-color:#FFF;
    }

    #content {
        position:static;
        margin-top:100px;
    }

Dangling Pointer

If any pointer is pointing the memory address of any variable but after some variable has deleted from that memory location while pointer is still pointing such memory location. Such pointer is known as dangling pointer and this problem is known as dangling pointer problem.

#include<stdio.h>

  int *call();

  void main(){

      int *ptr;
      ptr=call();

      fflush(stdin);
      printf("%d",*ptr);

   }

 int * call(){

   int x=25;
   ++x;
   return &x;
 }

Output: Garbage value

Note: In some compiler you may get warning message returning address of local variable or temporary

Explanation: variable x is local variable. Its scope and lifetime is within the function call hence after returning address of x variable x became dead and pointer is still pointing ptr is still pointing to that location.

Solution of this problem: Make the variable x is as static variable. In other word we can say a pointer whose pointing object has been deleted is called dangling pointer.

Memory Leak

In computer science, a memory leak occurs when a computer program incorrectly manages memory allocations. As per simple we have allocated the memory and not Free other language term say not release it call memory leak it is fatal to application and unexpected crash.

Should you want to resort to using a plug-in, malihu-custom-scrollbar-plugin, could do the job. It performs an actual scroll, not just a jump. You can even specify the speed/momentum of scroll. It also lets you set up a menu (list of links to scroll to), which have their CSS changed based on whether the anchors-to-scroll-to are in viewport, and other useful features.

There are demo on the author's site and let our company site serve as a real-world example too.

If you've tried everything mentioned here and it didn't work, make sure you also have added angular material to your project. If not, just run the following command in the terminal to add it:

ng add @angular/material

After it successfully gets added, wait for the project to get refreshed, and the error will be automatically gone.

iOS 9 forces connections that are using HTTPS to be TLS 1.2 to avoid recent vulnerabilities. In iOS 8 even unencrypted HTTP connections were supported, so that older versions of TLS didn't make any problems either. As a workaround, you can add this code snippet to your Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

To prevent lagging, you need to not only set the text properties in the onItemSelected listener, but also in the Activity's onCreate method (but it's a little tricky).

Specifically, you need to put this in onCreate after setting the adapter:

spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);

And then put this in onItemSelected:

((TextView) view).setTextColor(backgroundColor);

Here is a full example:

@Override  
protected void onCreate(Bundle savedInstanceState)
{  
    Spinner spinner = (Spinner) findViewById(R.id.spinner); 

    //Set the choices on the spinner by setting the adapter.  
    spinner.setAdapter(new SpinnerAdapter(toolbar.getContext(), new String[]{"Overview", "Story", "Specifications", "Poll", "Video"}, accentColor, backgroundColor));

    //Set the text color of the Spinner's selected view (not a drop down list view) 
    spinner.setSelection(0, true);
    View v = spinner.getSelectedView();
    ((TextView)v).setTextColor(backgroundColor);

    //Set the listener for when each option is clicked.  
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {  

        @Override  
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
        {  
           //Change the selected item's text color  
           ((TextView) view).setTextColor(backgroundColor);
        }  

        @Override  
        public void onNothingSelected(AdapterView<?> parent)
        {  
        }  
    });  

}  

For more details, see my question.

When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String and &str:

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    owned_string.push_str(borrowed_string);
    println!("{}", owned_string);
}

Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String and String, as &String can be dereferenced as &str.

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    owned_string.push_str(&another_owned_string);
    println!("{}", owned_string);
}

After this, another_owned_string is untouched (note no mut qualifier). There's another variant that consumes the String but doesn't require it to be mutable. This is an implementation of the Add trait that takes a String as the left-hand side and a &str as the right-hand side:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let new_owned_string = owned_string + borrowed_string;
    println!("{}", new_owned_string);
}

Note that owned_string is no longer accessible after the call to +.

What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!:

fn main() {
    let borrowed_string: &str = "hello ";
    let another_borrowed_string: &str = "world";
    
    let together = format!("{}{}", borrowed_string, another_borrowed_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{borrowed_string}{another_borrowed_string}");

    println!("{}", together);
}

Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String, we can use the fact that String also can be formatted:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    let together = format!("{}{}", owned_string, another_owned_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{owned_string}{another_owned_string}");
    println!("{}", together);
}

You don't have to use format! though. You can clone one string and append the other string to the new string:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let together = owned_string.clone() + borrowed_string;
    println!("{}", together);
}

Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!
