If there's Lodash in your project, use upperFirst.

Use an interval to check

You can setup an interval to keep checking if the user has scrolled then do something accordingly.

Borrowing from the great John Resig in his article.

Example:

    let didScroll = false;

    window.onscroll = () => didScroll = true;

    setInterval(() => {
        if ( didScroll ) {
            didScroll = false;
            console.log('Someone scrolled me!')
        }
    }, 250);

See live example

We can use params, new feature of the UI-Router:

API Reference / ui.router.state / $stateProvider

params A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.

See the part: "...or defines additional non-url parameters..."

So the state def would be:

$stateProvider
  .state('home', {
    url: "/home",
    templateUrl: 'tpl.html',
    params: { hiddenOne: null, }
  })

Few examples form the doc mentioned above:

// define a parameter's default value
params: {
  param1: { value: "defaultValue" }
}
// shorthand default values
params: {
  param1: "defaultValue",
  param2: "param2Default"
}

// param will be array []
params: {
  param1: { array: true }
}

// handling the default value in url:
params: {
  param1: {
    value: "defaultId",
    squash: true
} }
// squash "defaultValue" to "~"
params: {
  param1: {
    value: "defaultValue",
    squash: "~"
  } }

EXTEND - working example: http://plnkr.co/edit/inFhDmP42AQyeUBmyIVl?p=info

Here is an example of a state definition:

 $stateProvider
  .state('home', {
      url: "/home",
      params : { veryLongParamHome: null, },
      ...
  })
  .state('parent', {
      url: "/parent",
      params : { veryLongParamParent: null, },
      ...
  })
  .state('parent.child', { 
      url: "/child",
      params : { veryLongParamChild: null, },
      ...
  })

This could be a call using ui-sref:

<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
  })">home</a>

<a ui-sref="parent({ 
    veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
  })">parent</a>

<a ui-sref="parent.child({
    veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',  
    veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
  })">parent.child</a>

Check the example here

you can use 'capture.output' like below. This allows you to use the data later:

log <- capture.output({
  test <- CensReg.SMN(cc=cc,x=x,y=y, nu=NULL, type="Normal")
})

test$betas

  return user;
 }


 @RequestMapping(method = RequestMethod.GET,headers="Accept=application/json")
 public List<User> getAllUsers() {
  List<User> users=userShop.getAllUsers();
  return users;
 }


}

In the above example they going to display all user and particular id details now I want to use both id and name,

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

now I want to use both id and name

localhost:8093/plejson/shop/user/11/raju <-----------------like this it means we can use any one in this please help me out.....

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

"Curly Braces" are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another - kind of like how an English dictionary maps a word to its definition.

Python:

dict = {
    "a" : "Apple",
    "b" : "Banana",
}

They are also used to format strings, instead of the old C style using %, like:

ds = ['a', 'b', 'c', 'd']
x = ['has_{} 1'.format(d) for d in ds]

print x

['has_a 1', 'has_b 1', 'has_c 1', 'has_d 1']

They are not used to denote code blocks as they are in many "C-like" languages.

C:

if (condition) {
    // do this
}

Indeed, the compiler doesn't know how to convert this anonymous type (the new { x.ServerName, x.ProcessID, x.Username } part) to a PInfo object.

var dataset = entities.processlists
    .Where(x => x.environmentID == environmentid && x.ProcessName == processname && x.RemoteIP == remoteip && x.CommandLine == commandlinepart)
    .Select(x => new { x.ServerName, x.ProcessID, x.Username }).ToList();

This gives you a list of objects (of anonymous type) you can use afterwards, but you can't return that or pass that to another method.

If your PInfo object has the right properties, it can be like this :

var dataset = entities.processlists
    .Where(x => x.environmentID == environmentid && x.ProcessName == processname && x.RemoteIP == remoteip && x.CommandLine == commandlinepart)
    .Select(x => new PInfo 
                 { 
                      ServerName = x.ServerName, 
                      ProcessID = x.ProcessID, 
                      UserName = x.Username 
                 }).ToList();

Assuming that PInfo has at least those three properties.

Both query allow you to fetch only the wanted columns, but using an existing type (like in the second query) allows you to send this data to other parts of your app.

There are a number of approaches here- and though the position is that typically users should not be restricted when it comes to zooming for accessibility purposes, there may be incidences where is it required:

Render the page at the width of the device, dont scale:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Prevent scaling- and prevent the user from being able to zoom:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

Removing all zooming, all scaling

<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />

I have to set the selection style to UITableViewCellSelectionStyleDefault for custom background color to work. If any other style, the custom background color will be ignored. Tested on iOS 8.

The full code for the cell as follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"MyCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    // This is how you change the background color
    cell.selectionStyle = UITableViewCellSelectionStyleDefault;
    UIView *bgColorView = [[UIView alloc] init];
    bgColorView.backgroundColor = [UIColor redColor];
    [cell setSelectedBackgroundView:bgColorView];

    return cell;
}

$("input[required]").attr("oninvalid", "this.setCustomValidity('Say Somthing!')");

this work if you move to previous or next field by mouse, but by enter key, this is not work !!!

The ffmpeg wiki links back to this page in reference to "How to split video efficiently". I'm not convinced this page answers that question, so I did as @AlcubierreDrive suggested…

echo "Two commands" 
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 -sn test1.mkv
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:30:00 -t 01:00:00 -sn test2.mkv
echo "One command" 
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 \
  -sn test3.mkv -vcodec copy -acodec copy -ss 00:30:00 -t 01:00:00 -sn test4.mkv

Which outputs...

One command  HD 3m30.79 #1 wins  

SD file = 1.35GB DVB transport stream
HD file = 3.14GB DVB transport stream

Conclusion

The single command is better if you are handling HD, it agrees with the manuals comments on using -ss after the input file to do a 'slow seek'. SD files have a negligible difference.

The two command version should be quicker by adding another -ss before the input file for the a 'fast seek' followed by the more accurate slow seek.

You can set a tabindex to the DOM element. This will trigger a blur event when the user click outside the DOM element.

Demo

<div tabindex="1">
    Focus me
</div>

document.querySelector("div").onblur = function(){
   console.log('clicked outside')
}
document.querySelector("div").onfocus = function(){
   console.log('clicked inside')
}

I had a similar issue. Maybe this answer will help you as well.

It looks like you have two different errors going on:

1. Unable to connect to host 127.0.0.1 on port 7055
2. Error: no display specified

The reason for the Unable to connect error is that the version of Selenium Server does not know how to work with the newer version of Firefox. You need to download a newer version of the Selenium Server that supports the newer version of Firefox.

The reason for the Error: no display specified error is that Firefox is being launched, but there is no X server (GUI) running on the remote host. You can use X11 forwarding to run Firefox on the remote host, but display it on your local host. On Mac OS X, you will need to download XQuartz in order to use X11 forwarding.

If a number n is not a prime, it can be factored into two factors a and b:

n = a * b

Now a and b can't be both greater than the square root of n, since then the product a * b would be greater than sqrt(n) * sqrt(n) = n. So in any factorization of n, at least one of the factors must be smaller than the square root of n, and if we can't find any factors less than or equal to the square root, n must be a prime.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Internet Explorer (under version 9) does not natively support rounded corners.

There's an amazing script that will magically add it for you: CSS3 PIE.

I've used it a lot of times, with amazing results.

toolbar = (Toolbar) getView().findViewById(R.id.toolbar);
AppCompatActivity activity = (AppCompatActivity) getActivity();
activity.setSupportActionBar(toolbar);

Dim o
Set o = CreateObject("MSXML2.XMLHTTP")
o.open "GET", "http://www.example.com", False
o.send
' o.responseText now holds the response as a string.

Try following code to get count of files in the folder

string strDocPath = Server.MapPath('Enter your path here'); 
int docCount = Directory.GetFiles(strDocPath, "*", 
SearchOption.TopDirectoryOnly).Length;

Yes, std::sort() with third parameter (function or object) would be easier. An example: http://www.cplusplus.com/reference/algorithm/sort/

First of all create on file and then convert your xml data in array and retrieve that data in json format for ajax success response.

Try as below:

$(document).ready(function () {
    $.ajax({
        type: "POST",
        url: "sample.php",            
        success: function (response) {
            var obj = $.parseJSON(response);
            for(var i=0;i<obj.length;i++){
                // here you can add html through loop
            }                
        }
    });
});  

sample.php

$xml = "YOUR XML FILE PATH";
$json = json_encode((array)simplexml_load_string($xml)),1);
echo $json;

It took me a while to implement the other responses, as I'm using Angular 8 (tested up to 10). I ended up with the following code (heavily inspired by Hasan).

Note that for the name to be set, the header Access-Control-Expose-Headers MUST include Content-Disposition. To set this in django RF:

http_response = HttpResponse(package, content_type='application/javascript')
http_response['Content-Disposition'] = 'attachment; filename="{}"'.format(filename)
http_response['Access-Control-Expose-Headers'] = "Content-Disposition"

In angular:

  // component.ts
  // getFileName not necessary, you can just set this as a string if you wish
  getFileName(response: HttpResponse<Blob>) {
    let filename: string;
    try {
      const contentDisposition: string = response.headers.get('content-disposition');
      const r = /(?:filename=")(.+)(?:")/
      filename = r.exec(contentDisposition)[1];
    }
    catch (e) {
      filename = 'myfile.txt'
    }
    return filename
  }

  
  downloadFile() {
    this._fileService.downloadFile(this.file.uuid)
      .subscribe(
        (response: HttpResponse<Blob>) => {
          let filename: string = this.getFileName(response)
          let binaryData = [];
          binaryData.push(response.body);
          let downloadLink = document.createElement('a');
          downloadLink.href = window.URL.createObjectURL(new Blob(binaryData, { type: 'blob' }));
          downloadLink.setAttribute('download', filename);
          document.body.appendChild(downloadLink);
          downloadLink.click();
        }
      )
  }

  // service.ts
  downloadFile(uuid: string) {
    return this._http.get<Blob>(`${environment.apiUrl}/api/v1/file/${uuid}/package/`, { observe: 'response', responseType: 'blob' as 'json' })
  }

Query Analyzer buffers messages. The PRINT and RAISERROR statements both use this buffer, but the RAISERROR statement has a WITH NOWAIT option. To print a message immediately use the following:

RAISERROR ('Your message', 0, 1) WITH NOWAIT

RAISERROR will only display 400 characters of your message and uses a syntax similar to the C printf function for formatting text.

Please note that the use of RAISERROR with the WITH NOWAIT option will flush the message buffer, so all previously buffered information will be output also.

In JSP, you'd normally like to use JSTL <fmt:formatDate> for this. You can of course also throw in a scriptlet with SimpleDateFormat, but scriptlets are strongly discouraged since 2003.

Assuming that ${bean.date} returns java.util.Date, here's how you can use it:

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
...
<fmt:formatDate value="${bean.date}" pattern="yyyy-MM-dd HH:mm:ss" />

If you're actually using a java.util.Calendar, then you can invoke its getTime() method to get a java.util.Date out of it that <fmt:formatDate> accepts:

<fmt:formatDate value="${bean.calendar.time}" pattern="yyyy-MM-dd HH:mm:ss" />

Or, if you're actually holding the date in a java.lang.String (this indicates a serious design mistake in the model; you should really fix your model to store dates as java.util.Date instead of as java.lang.String!), here's how you can convert from one date string format e.g. MM/dd/yyyy to another date string format e.g. yyyy-MM-dd with help of JSTL <fmt:parseDate>.

<fmt:parseDate pattern="MM/dd/yyyy" value="${bean.dateString}" var="parsedDate" />
<fmt:formatDate value="${parsedDate}" pattern="yyyy-MM-dd" />

You can make recursive call if sub directories exists

import java.io.File;

class DeleteDir {
public static void main(String args[]) {
deleteDirectory(new File(args[0]));
}

static public boolean deleteDirectory(File path) {
if( path.exists() ) {
  File[] files = path.listFiles();
  for(int i=0; i<files.length; i++) {
     if(files[i].isDirectory()) {
       deleteDirectory(files[i]);
     }
     else {
       files[i].delete();
     }
  }
}
return( path.delete() );
}
}

Why so complicated?

Let's assume you store the number of days to add in a variable called days_to_add.

Then this short one should do it:

calc_date = new Date(Date.now() +(days_to_add * 86400000));

With Date.now() you get the actual unix timestamp as milliseconds and then you add as many milliseconds as you want to add days to. One day is 24h60min60s*1000ms = 86400000 ms or 864E5.

HTML or Jsp Page         
<input type="text" name="1UserName">
<input type="text" name="2Password">
<Input type="text" name="3MobileNo">
<input type="text" name="4country">
and so on...
in java Code 

 SortedSet ss = new TreeSet();
 Enumeration<String> enm=request.getParameterNames();
while(enm.hasMoreElements())
{
    String pname = enm.nextElement();
    ss.add(pname);
}
Iterator i=ss.iterator();
while(i.hasNext())
{
    String param=(String)i.next();
    String value=request.getParameter(param);
}

One of the way you can achieve this is:

1. Create an executable Jar file
2. Create a batch file to run the above jar and launch the desktop java application.
3. Use Batch2Exe converter and covert to batch file to Exe.
4. During above conversion, you can change the icon to that of your choice.(must of valid .ico file)
5. Place the short cut for the above exe on desktop.

Now your java program can be opened in a fancy way just like any other MSWindows apps.! :)

At one point I needed to accurately push log events from Cygwin to the Windows Event log. I wanted the messages in WEVL to be custom, have the correct exit code, details, priorities, message, etc. So I created a little Bash script to take care of this. Here it is on GitHub, logit.sh.

Some excerpts:

usage: logit.sh [-h] [-p] [-i=n] [-s] <description>
example: logit.sh -p error -i 501 -s myscript.sh "failed to run the mount command"

Here is the temporary file contents part:

LGT_TEMP_FILE="$(mktemp --suffix .cmd)"
cat<<EOF>$LGT_TEMP_FILE
    @echo off
    set LGT_EXITCODE="$LGT_ID"
    exit /b %LGT_ID%
EOF
unix2dos "$LGT_TEMP_FILE"

Here is a function to to create events in WEVL:

__create_event () {
    local cmd="eventcreate /ID $LGT_ID /L Application /SO $LGT_SOURCE /T $LGT_PRIORITY /D "
    if [[ "$1" == *';'* ]]; then
        local IFS=';'
        for i in "$1"; do
            $cmd "$i" &>/dev/null
        done
    else
        $cmd "$LGT_DESC" &>/dev/null
    fi
}

Executing the batch script and calling on __create_event:

cmd /c "$(cygpath -wa "$LGT_TEMP_FILE")"
__create_event

For my windows folks I discovered a way to change ReactJS port to run on any port you want.Before running the server go to

 node_modules/react-scripts/scripts/start.js

In it, search for the line below and change the port number to your desired port

 var DEFAULT_PORT = process.env.PORT || *4000*;

And you are good to go.

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

is it too late?

I personally agree with Beatrice Len, I used paramiko maybe is an extra step for windows, but I have an example project git hub, feel free to clone or ask me.

Yes we can, "Anonymous classes enable you to make your code more concise. They enable you to declare and instantiate a class at the same time. They are like local classes except that they do not have a name"->>Java Doc

I had a similar problem... Android Emulator doesn't open. You need to discover the reason of this... You could run your emulator from the command line. For this you could copy and paste your command line from "Run" or "AVD" Android Studio console. For example:

"{path}\android-sdk\tools\emulator.exe -avd Default_Nexus_5 -netspeed full -netdelay none"

When you launch it from a command line terminal, It give you a message with the error. In my case it was useful for discover the problem:

..\android-sdk\tools>emulator: ERROR: x86 emulation currently requires hardware acceleration! Please ensure Intel HAXM is properly installed and usable. CPU acceleration status: HAX kernel module is not installed!

• I needed to activate GPU acceleration with a tool to enable it on my machine. I solved it installing from SDK Manager the tool HAXM...

• I had another problem... For example i had assigned a bad url for skin path of my virtual device... To solve it I have configured my virtual device with a valid skin from my platform sdk: '{path}\android-sdk\platforms\android-{number}\skins{SCREEN_SIZE}'

Now it is opening fine.

Update 8/8/2019:

For newer version of Android SDK, emulator path should be:

"{path}\android-sdk\emulator\emulator.exe"

reference (thank you @CoolMind)

You can achieve fall through like c++ by the goto keyword.

EX:

switch(num)
{
   case 1:
      goto case 3;
   case 2:
      goto case 3;
   case 3:
      //do something
      break;
   case 4:
      //do something else
      break;
   case default:

Your problem is in your php file. When you use jquery serialize() method you are sending a string, so you can not treat it like an array. Make a var_dump($_post) and you will see what I am talking about.

Tkinter supports a mechanism called protocol handlers. Here, the term protocol refers to the interaction between the application and the window manager. The most commonly used protocol is called WM_DELETE_WINDOW, and is used to define what happens when the user explicitly closes a window using the window manager.

You can use the protocol method to install a handler for this protocol (the widget must be a Tk or Toplevel widget):

Here you have a concrete example:

import tkinter as tk
from tkinter import messagebox

root = tk.Tk()

def on_closing():
    if messagebox.askokcancel("Quit", "Do you want to quit?"):
        root.destroy()

root.protocol("WM_DELETE_WINDOW", on_closing)
root.mainloop()

Format your string like so:

[#                    ] 1%\r

Note the \r character. It is the so-called carriage return that will move the cursor back to the beginning of the line.

Finally, make sure you use

System.out.print()

and not

System.out.println()

select * from Table1 left join Table2 on Table1.id = Table2.id

In the first query Left join compares left-sided table table1 to right-sided table table2.

In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.

select * from Table2 right join Table1 on Table1.id = Table2.id

In the first query Right join compares right-sided table table1 to left-sided table table2.

In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.

Both queries will give the same result because the order of table declaration in query are different like you are declaring table1 and table2 in left and right respectively in first left join query, and also declaring table1 and table2 in right and left respectively in second right join query.

This is the reason why you are getting the same result in both queries. So if you want different result then execute this two queries respectively,

select * from Table1 left join Table2 on Table1.id = Table2.id

select * from Table1 right join Table2 on Table1.id = Table2.id

javatuples is a dedicated project for tuples in Java.

Unit<A> (1 element)

page-break-inside: avoid; gave me trouble using wkhtmltopdf.

To avoid breaks in the text add display: table; to the CSS of the text-containing div.

I hope this works for you too. Thanks JohnS.

I think this is the simplest way to get the result you want from a formData FormData object:

const jsonData = {};

for(const [key, value] of formData) {
    jsonData[key] = value;
}

Comparator is a functional interface, and Integer::max complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int values and returns an int - just as you'd expect a Comparator<Integer> to (again, squinting to ignore the Integer/int difference).

However, I wouldn't expect it to do the right thing, given that Integer.max doesn't comply with the semantics of Comparator.compare. And indeed it doesn't really work in general. For example, make one small change:

for (int i = 1; i <= 20; i++)
    list.add(-i);

... and now the max value is -20 and the min value is -1.

Instead, both calls should use Integer::compare:

System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

Best way to do this without blocking the UI thread is to use Async and Await introduced in .net 4.5.
You can paste this in your code just change the Browser to your webbrowser name. This way, your thread awaits the page to load, if it doesnt on time, it stops waiting and your code continues to run:

private async Task PageLoad(int TimeOut)
    {
        TaskCompletionSource<bool> PageLoaded = null;
        PageLoaded = new TaskCompletionSource<bool>();
        int TimeElapsed = 0;
        Browser.DocumentCompleted += (s, e) =>
        {
            if (Browser.ReadyState != WebBrowserReadyState.Complete) return;
            if (PageLoaded.Task.IsCompleted) return; PageLoaded.SetResult(true);
        };
        //
        while (PageLoaded.Task.Status != TaskStatus.RanToCompletion)
        {
            await Task.Delay(10);//interval of 10 ms worked good for me
            TimeElapsed++;
            if (TimeElapsed >= TimeOut * 100) PageLoaded.TrySetResult(true);
        }
    }

And you can use it like this, with in an async method, or in a button click event, just make it async:

private async void Button1_Click(object sender, EventArgs e)
{
   Browser.Navigate("www.example.com");
   await PageLoad(10);//await for page to load, timeout 10 seconds.
   //your code will run after the page loaded or timeout.
}

Another way of getting the first row and preserving the index:

x = df.first('d') # Returns the first day. '3d' gives first three days.

This is how I did it

import requests
from PIL import Image
from io import BytesIO

url = 'your_url'
files = {'file': ("C:/Users/shadow/Downloads/black.jpeg", open('C:/Users/shadow/Downloads/black.jpeg', 'rb'),'image/jpg')}
response = requests.post(url, files=files)

img = Image.open(BytesIO(response.content))
img.show()

Yes, there is a problem with pointers. Very likely you're using one that's not initialized properly, but it's also possible that you're messing up your memory management with double frees or some such.

To avoid uninitialized pointers as local variables, try declaring them as late as possible, preferably (and this isn't always possible) when they can be initialized with a meaningful value. Convince yourself that they will have a value before they're being used, by examining the code. If you have difficulty with that, initialize them to a null pointer constant (usually written as NULL or 0) and check them.

To avoid uninitialized pointers as member values, make sure they're initialized properly in the constructor, and handled properly in copy constructors and assignment operators. Don't rely on an init function for memory management, although you can for other initialization.

If your class doesn't need copy constructors or assignment operators, you can declare them as private member functions and never define them. That will cause a compiler error if they're explicitly or implicitly used.

Use smart pointers when applicable. The big advantage here is that, if you stick to them and use them consistently, you can completely avoid writing delete and nothing will be double-deleted.

Use C++ strings and container classes whenever possible, instead of C-style strings and arrays. Consider using .at(i) rather than [i], because that will force bounds checking. See if your compiler or library can be set to check bounds on [i], at least in debug mode. Segmentation faults can be caused by buffer overruns that write garbage over perfectly good pointers.

Doing those things will considerably reduce the likelihood of segmentation faults and other memory problems. They will doubtless fail to fix everything, and that's why you should use valgrind now and then when you don't have problems, and valgrind and gdb when you do.

the issue happened with me, I resolved by removing the scope tag only and built successfully.

Adding a 100% to the width and height attributes of its iframe has always worked for me. For example

<iframe width="100%" height="100%" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.co.in/maps?f=q&amp;source=s_q&amp;hl=en&amp;geocode=+&amp;q=surat&amp;ie=UTF8&amp;hq=&amp;hnear=Surat,+Gujarat&amp;ll=21.195,72.819444&amp;spn=0.36299,0.676346&amp;t=m&amp;z=11&amp;output=embed"></iframe><br />

Since Java 1.5 you can use the String.format method. For example, to do the same thing as your example:

String format = String.format("%0%d", digits);
String result = String.format(format, num);
return result;

In this case, you're creating the format string using the width specified in digits, then applying it directly to the number. The format for this example is converted as follows:

%% --> %
0  --> 0
%d --> <value of digits>
d  --> d

So if digits is equal to 5, the format string becomes %05d which specifies an integer with a width of 5 printing leading zeroes. See the java docs for String.format for more information on the conversion specifiers.

this error occur when you change your php version: it's very simple to suppress this error message

To suppress the DEPRECATED Error message, just add below code into your index.php file:

init_set('display_errors',False);

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

To lock the screen by code you have to use the actual rotation of the screen (0, 90, 180, 270) and you have to know the natural position of it, in a smartphone the natural position will be portrait and in a tablet, it will be landscape.

Here's the code (lock and unlock methods), it has been tested in some devices (smartphones and tablets) and it works great.

public static void lockScreenOrientation(Activity activity)
{   
    WindowManager windowManager =  (WindowManager) activity.getSystemService(Context.WINDOW_SERVICE);   
    Configuration configuration = activity.getResources().getConfiguration();   
    int rotation = windowManager.getDefaultDisplay().getRotation(); 

    // Search for the natural position of the device    
    if(configuration.orientation == Configuration.ORIENTATION_LANDSCAPE &&  
       (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) ||  
       configuration.orientation == Configuration.ORIENTATION_PORTRAIT &&   
       (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270))   
    {   
        // Natural position is Landscape    
        switch (rotation)   
        {   
            case Surface.ROTATION_0:    
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);    
                break;      
            case Surface.ROTATION_90:   
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT); 
            break;      
            case Surface.ROTATION_180: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE); 
                break;          
            case Surface.ROTATION_270: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
                break;
        }
    }
    else
    {
        // Natural position is Portrait
        switch (rotation) 
        {
            case Surface.ROTATION_0: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
            break;   
            case Surface.ROTATION_90: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
            break;   
            case Surface.ROTATION_180: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT); 
                break;          
            case Surface.ROTATION_270: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE); 
                break;
        }
    }
}

public static void unlockScreenOrientation(Activity activity)
{
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
}

I had some problems to find this option in newer versions, so for Mysql Workbench 6.3, go to schemas and enter in your connection:

Go to Tools -> Data Export

Click on Advanced Options

Scroll down and uncheck extended-inserts

Then export the data you want and you will see the result file as this:

Same problem with VS 2012 Pro with a disk publish target. Project used to publish correctly but started doing this issue where it failed to copy the files to the destination folder.

Solution was to edit the publish profile, change the mode from Release (Any CPU) to debug then back to Release (Any CPU). Doing this causes the PublishProfiles\projname.pubxml.user file to be rewritten (as described above). Looks like it added the LastUsedBuild,LastUsedPlatform and TimeStampOfAssociatedLegacyPublishXmlFile elements under the propertygroup node. After the publish is complete, it adds another ItemGroup with individual files and publish times.

if you're receiving the error in parameter, so keep any or any[] type of input like below

getOptionLabel={(option: any) => option!.name}

 <Autocomplete
    options={tests}
    getOptionLabel={(option: any) => option!.name}
    ....
  />

Since Java 7 you can use java.util.Objects.equals(Object a, Object b):

These utilities include null-safe or null-tolerant methods

Long id1 = null;
Long id2 = 0l;
Objects.equals(id1, id2));

StringBuilder sb = new StringBuilder(name);
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));  
return sb.toString();

Here's an example that puts the Now() value in column A.

Sub move()
    Dim i As Integer
    Dim sh1 As Worksheet
    Dim sh2 As Worksheet
    Dim nextRow As Long
    Dim copyRange As Range
    Dim destRange As Range

    Application.ScreenUpdating = False

        Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
        Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
        Set copyRange = sh1.Range("A1:A5")

        i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4

        Set destRange = sh2.Range("B" & i)

        destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
        destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")

        copyRange.Clear

    Application.ScreenUpdating = True

End Sub

There are better ways of getting the last row in column B than using a While loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3 have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

I am almost sure you are not actually getting it installed correctly. Since you are trying to install it globally, you will need to run it with sudo:

sudo npm install -g bower

@Jon's answer is great and will get you where you need to go. So why is your code printing out what it is. The answer: You're not writing out the contents of your list, but the String representation of your list itself, by an implicit call to Lists.verbList.ToString(). Object.ToString() defines the default behavior you're seeing here.

I can recommend Ninject. It's incredibly fast and easy to use but only if you don't need XML configuration, else you should use Windsor.

This, from a posting in my blog a few months ago, has gone from being an idea that I thought was cool to one of the best little hacks I've coughed up in recent memory. I quote it in full here:

==================

I spend a lot of time in bash. For the uninitiated, bash is a system that you'll find on most unix machines and, thankfully, some windows and every Mac out there. At first blush, it's no more than a command-line interface, and therefore off the radar of most users who see such things as an anachronism they'd rather forget.

I do nearly everything in bash. I READ MY EMAIL FROM A COMMAND LINE, which is why I eschew marked-up email. I navigate directories, edit files, engage in my daily source code checkout and delivery, search for files, search inside files, reboot my machine, and even occasionally browse web pages from the command line. bash is the heart and soul of my digital existence.

The trouble is that I tend to have about 6 bash windows open at a time. At work today, I had one running a web server, another fiddling with my database, a third, fourth, and fifth editing different files, while a sixth was grinding away through my machine trying to record the names of every file on the system. Why? Because it's handy to be able to search through such an archive if you want to know where to find an object by filename.

When you do this, you end up with lots of windows in your control bar named simply, "bash." This is fine if you only have one of them, but its agony when you have 6 or more.... and two dozen other things going on. I have three monitors under the simultaneous command of one keyboard/mouse pair and I still feel the need for more. Each of those windows has several bash terminals open.

So I've plunked this together. First, place these lines in your .bash_profile:

  export PROMPT_COMMAND='export TRIM=`~/bin/trim.pl`'
  export PS1="\[\e]0;\$TRIM\a\]\$TRIM> "
  trap 'CMD=`history|~/bin/hist.pl`;echo -en "\e]0;$TRIM> $CMD\007"' DEBUG

I went through and wrote dozens of paragraphs on how this all works and exactly why it is set up the way it is, but you're not really interested. Trust me. There is an entire chapter of a book in why I did "CMD=...; echo..." on that third line. Many people (including bluehost, where my other domain is hosted) are still using and old version of bash with major bugs in how it handles traps, so we're stuck with this. You can remove the CMD and replace it with $BASH_COMMAND if you are current on your bash version and feel like doing the research.

Anyway, the first script I use is here. It creates a nice prompt that contains your machine name and directory, chopped down to a reasonable length:

                       ============trim.pl===========
  #!/usr/bin/perl

  #It seems that my cygwin box doesn't have HOSTNAME available in the 
  #environment - at least not to scripts - so I'm getting it elsewhere.
  open (IN, "/usr/bin/hostname|");
  $hostname = <IN>;
  close (IN);
  $hostname =~ /^([A-Za-z0-9-]*)/;
  $host_short = $1;

  $preamble = "..." if (length($ENV{"PWD"})>37);

  $ENV{"PWD"} =~ /(.{1,37}$)/;
  $path_short = $1;

  print "$host_short: $preamble$path_short";

                        ==============================

There's a warning at the top of this blog post that you should read now before you start asking stupid questions like, "Why didn't you just use the HOSTNAME environment variable via @ENV?" Simple: Because that doesn't work for all the systems I tried it on.

Now for the really cool bit. Remember line 3 of the .bash_profile addition?

  trap 'CMD=`history|~/bin/hist.pl`;echo -en "\e]0;$TRIM> $CMD\007"' DEBUG

It's dumping the trim.pl script output in the same container as before, printing to both the command prompt and the window title, but this time it's adding the command that you just typed! This is why you don't want to be doing all of this in your .bashrc: any script you run (on my machine, man is one of them) will trigger this thing on every line. man's output gets seriously garbled by what we're doing here. We're not exactly playing nice with the terminal.

To grab the command you just typed, we take the bash's history and dice it up a bit:

                        ===========hist.pl============
#!/usr/bin/perl

while (<STDIN>)
{
        $line = $_
}

chomp $line;
$line =~ /^.{27}(.*)/;
print $1;
                        ==============================

So now, I have a bazillion windows going and they say things like:

  castro: /home/ronb blog
  Ron-D630: /C/ronb/rails/depot script/server
  Ron-D630: /C/ronb/rails/depot mysql -u ron -p
  Ron-D630: /C/ronb/rails/depot find . > /C/ronb/system.map
  Ron-D630: /C/ronb/rails/depot vi app/views/cart.html.erb
  Ron-D630: /C/perforce/depot/ p4 protect
  Ron-D630: /C/perforce/depot/ p4 sync -f
  Ron-D630: /C/perforce/depot/

From the happy little bar at the bottom of the screen, I can now tell which is which at a moment's glance. And because we've set PS1, as soon as a command finishes executing, the command name is replaced by just the output of trim.pl again.

UPDATE (same day): This stuff (the .bash_profile entries) laid all kinds of hell on me when I tried it in my .bashrc. Your .bashrc is executed by non-interactive scripts whenever you invoke bash as a language. I hit this when I was trying to use man. All sorts of garbage (the complete text of my .bashrc, plus escape charecters) showed up at the top of the man page. I would suggest testing this gem with a quick 'man man' invocation at the command line once you get it all together.

I guess it's time for me to pull the custom garbage out of my .bashrc and put it where it belongs...

Incedentally, I found myself typing 'man trap' at one point in this process.

In case someone is looking I reposted my answer from: SelectListItem selected = true not working in view

After searching myself for answer to this problem - I had some hints along the way but this is the resulting solution for me. It is an extension Method. I am using MVC 5 C# 4.52 is the target. The code below sets the Selection to the First Item in the List because that is what I needed, you might desire simply to pass a string and skip enumerating - but I also wanted to make sure I had something returned to my SelectList from the DB)

Extension Method:

public static class SelectListextensions {

public static System.Web.Mvc.SelectList SetSelectedValue

(this System.Web.Mvc.SelectList list, string value) { if (value != null) { var selected = list.Where(x => x.Text == value).FirstOrDefault(); selected.Selected = true;
} return list; }
}

And for those who like the complete low down (like me) here is the usage. The object Category has a field defined as Name - this is the field that will show up as Text in the drop down. You can see that test for the Text property in the code above.

Example Code:

SelectList categorylist = new SelectList(dbContext.Categories, "Id", "Name");

SetSelectedItemValue(categorylist);

select list function:

private SelectList SetSelectedItemValue(SelectList source) { Category category = new Category();

SelectListItem firstItem = new SelectListItem();

int selectListCount = -1;

if (source != null && source.Items != null)
{
    System.Collections.IEnumerator cenum = source.Items.GetEnumerator();

    while (cenum.MoveNext())
    {
        if (selectListCount == -1)
        {
            selectListCount = 0;
        }

        selectListCount += 1;

        category = (Category)cenum.Current;

        source.SetSelectedValue(category.Name);

        break;
    }
    if (selectListCount > 0)
    {
        foreach (SelectListItem item in source.Items)
        {
            if (item.Value == cenum.Current.ToString())
            {
                item.Selected = true;

                break;
            }
        }
    }
}
return source;

}

You can make this a Generic All Inclusive function / Extension - but it is working as is for me

You don't need the assignment, list.append(x) will always append x to a and therefore there's no need te redefine a.

a = []
for i in range(5):    
    a.append(i)
print(a)

is all you need. This works because lists are mutable.

Also see the docs on data structures.

You can get the names from the schema by doing

spark_df.schema.names

Printing the schema can be useful to visualize it as well

spark_df.printSchema()

<style>
a{
cursor: default;
}
</style>

In the above code [cursor:default] is used. Default is the usual arrow cursor that appears.

And if you use [cursor: pointer] then you can access to the hand like cursor that appears when you hover over a link.

To know more about cursors and their appearance click the below link: https://www.w3schools.com/cssref/pr_class_cursor.asp

1. return None or return can be used to exit out of a function or program, both does the same thing
2. quit() function can be used, although use of this function is discouraged for making real world applications and should be used only in interpreter.

    import site
    
    def func():
        print("Hi")
        quit()
        print("Bye")

3. exit() function can be used, similar to quit() but the use is discouraged for making real world applications.

import site
    
    def func():
        print("Hi")
        exit()
        print("Bye")

4. sys.exit([arg]) function can be used and need to import sys module for that, this function can be used for real world applications unlike the other two functions.

import sys 
  height = 150
  
if height < 165: # in cm 
      
    # exits the program 
    sys.exit("Height less than 165")     
else: 
    print("You ride the rollercoaster.") 

5. os._exit(n) function can be used to exit from a process, and need to import os module for that.

I have been successfull at impersonating users in another domain, but only with a trust set up between the 2 domains.

var token = IntPtr.Zero;
var result = LogonUser(userID, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token);
if (result)
{
    return WindowsIdentity.Impersonate(token);
}

Typing brew install cmake as you did installs cmake. Now you can type cmake and use it.

If typing cmake doesn’t work make sure /usr/local/bin is your PATH. You can see it with echo $PATH. If you don’t see /usr/local/bin in it add the following to your ~/.bashrc:

export PATH="/usr/local/bin:$PATH"

Then reload your shell session and try again.

(all the above assumes Homebrew is installed in its default location, /usr/local. If not you’ll have to replace /usr/local with $(brew --prefix) in the export line)

As @DSM points out, you can do this more directly using the vectorised string methods:

df['Date'].str[-4:].astype(int)

Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):

df['Date'].str.extract('(?P<year>\d{4})').astype(int)

An alternative slightly more flexible way, might be to use apply (or equivalently map) to do this:

df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
             #  converts the last 4 characters of the string to an integer

The lambda function, is taking the input from the Date and converting it to a year.
You could (and perhaps should) write this more verbosely as:

def convert_to_year(date_in_some_format):
    date_as_string = str(date_in_some_format)  # cast to string
    year_as_string = date_in_some_format[-4:] # last four characters
    return int(year_as_string)

df['Date'] = df['Date'].apply(convert_to_year)

Perhaps 'Year' is a better name for this column...

If using function onclick DIV and then want to disable click it again you can use this :

for (var i=0;i<document.getElementsByClassName('ads').length;i++){
    document.getElementsByClassName('ads')[i].onclick = false;
}

Example :
HTML

<div id='mybutton'>Click Me</div>

Javascript

document.getElementById('mybutton').onclick = function () {
    alert('You clicked');
    this.onclick = false;
}

There is an express version on SSMS that has considerably fewer features but still has the basics.

Use the * command to handle multiple files at a time:

git reset HEAD *.prj
git reset HEAD *.bmp
git reset HEAD *gdb*

etc.

You can create static class inside your controller like this :

    @Controller
    public class HomeController {
        @Autowired
        private LoginServiceConfiguration loginServiceConfiguration;

        @RequestMapping(value = "/view", method = RequestMethod.GET)
        public ModelAndView display(HttpServletRequest req) {
            ModelAndView mav = new ModelAndView("home");
            mav.addObject("loginAction", loginServiceConfiguration.loginAction());
            return mav;
        }


        @Configuration
        public static class LoginServiceConfiguration {

            @Bean(name = "loginActionBean")
            @Scope("prototype")
            public LoginAction loginAction() {
                return new LoginAction();
            }
        }
}

UPDATED 2020 TRY THIS WAY

python manage.py runserver yourIp:8000

ALLOWED_HOSTS = ["*"]

Try accessing the placeholder attribute of the input and change its value like the following:

$('#some_input_id').attr('placeholder','New Text Here');

Can also clear the placeholder if required like:

$('#some_input_id').attr('placeholder','');

OpenFileDialog fdlg = new OpenFileDialog();
fdlg.Title = "C# Corner Open File Dialog" ;
fdlg.InitialDirectory = @"c:\" ;
fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*" ;
fdlg.FilterIndex = 2 ;
fdlg.RestoreDirectory = true ;
if(fdlg.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fdlg.FileName ;
}

In this code you can put your address in a text box.

Have you tried solution from jQuery UI docs? https://api.jqueryui.com/dialog/#method-open

As it say you can do like this...

In CSS:

.no-titlebar .ui-dialog-titlebar {
  display: none;
}

In JS:

$( "#dialog" ).dialog({
  dialogClass: "no-titlebar"
});

class A:
  pass

a = A()
str(a.__class__)

The sample code above (when input in the interactive interpreter) will produce '__main__.A' as opposed to 'A' which is produced if the __name__ attribute is invoked. By simply passing the result of A.__class__ to the str constructor the parsing is handled for you. However, you could also use the following code if you want something more explicit.

"{0}.{1}".format(a.__class__.__module__,a.__class__.__name__)

This behavior can be preferable if you have classes with the same name defined in separate modules.

The sample code provided above was tested in Python 2.7.5.

You can prefix the size requirement with - to left-justify:

sys.stdout.write("%-6s %-50s %-25s\n" % (code, name, industry))

To stop that Html5 popup/balloon in Web-kit browser use following CSS

::-webkit-validation-bubble-message { display: none; }

You can initialize an array by writing actual values it holds in curly braces on the right hand side like:

String[] strArr = { "one", "two", "three"};
int[] numArr = { 1, 2, 3};

In the same manner two-dimensional array or array-of-arrays holds an array as a value, so:

String strArrayOfArrays = { {"a", "b", "c"}, {"one", "two", "three"} };

Your example shows exactly that

double m[][] = {
    {0*0,1*0,2*0,3*0},
    {0*1,1*1,2*1,3*1},
    {0*2,1*2,2*2,3*2},
    {0*3,1*3,2*3,3*3}
};

But also the multiplication of number will also be performed and its the same as:

double m[][] = { {0, 0, 0, 0}, {0, 1, 2, 3}, {0, 2, 4, 6}, {0, 3, 6, 9} };

Your code loops until it reads a single word, then exits. So if you give it multiple words it will read the first and exit, while if you give it an empty input, it will loop forever. In any case, it will only print random garbage from uninitialized memory. This is apparently not what you want, but what do you want? If you just want to read and print the first word (if it exists), use if:

if (scanf("%15s", word) == 1)
    printf("%s\n", word);

If you want to loop as long as you can read a word, use while:

while (scanf("%15s", word) == 1)
    printf("%s\n", word);

Also, as others have noted, you need to give the word array a size that is big enough for your scanf:

char word[16];

Others have suggested testing for EOF instead of checking how many items scanf matched. That's fine for this case, where scanf can't fail to match unless there's an EOF, but is not so good in other cases (such as trying to read integers), where scanf might match nothing without reaching EOF (if the input isn't a number) and return 0.

edit

Looks like you changed your question to match my code which works fine when I run it -- loops reading words until EOF is reached and then exits. So something else is going on with your code, perhaps related to how you are feeding it input as suggested by David

You are most likely pushing a string 'NULL' to the table, rather then an actual NULL, but other things may be going on as well, an illustration:

mysql> CREATE TABLE date_test (pdd DATE NOT NULL);

mysql> INSERT INTO date_test VALUES (NULL);

C#

using System.Text.RegularExpressions;
...    
Regex.Match(
    input: "Check This String",
    pattern: "Regex Pattern",
    options: RegexOptions.IgnoreCase)

specifically: options: RegexOptions.IgnoreCase

You could store the last insert id in a variable :

INSERT INTO table1 (title,userid) VALUES ('test', 1); 
SET @last_id_in_table1 = LAST_INSERT_ID();
INSERT INTO table2 (parentid,otherid,userid) VALUES (@last_id_in_table1, 4, 1);    

Or get the max id frm table1

INSERT INTO table1 (title,userid) VALUES ('test', 1); 
INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(), 4, 1); 
SELECT MAX(id) FROM table1;   

This version is 26% shorter than yours but functions identically, even for redundant/ambiguous values (returns the first match, as yours does). However, it is probably twice as slow as yours, because it creates a list from the dict twice.

key = dict_obj.keys()[dict_obj.values().index(value)]

Or if you prefer brevity over readability you can save one more character with

key = list(dict_obj)[dict_obj.values().index(value)]

And if you prefer efficiency, @PaulMcGuire's approach is better. If there are lots of keys that share the same value it's more efficient not to instantiate that list of keys with a list comprehension and instead use use a generator:

key = (key for key, value in dict_obj.items() if value == 'value').next()

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

If you don't want a terminal window to pop up when you run your program, use pythonw.exe;
Otherwise, use python.exe

Regarding the syntax error: print is now a function in 3.x
So use instead:

print("a")

Here is the process that I ended up using. The main tool I used was Inkscape which was able to convert text alright.

• used Adobe Acrobat Pro actions with JavaScript to split-up the PDF sheets
• ran Inkscape Portable 0.48.5 from Windows Cmd to convert to SVG
• made some manual edits to a particular SVG XML attribute I was having issues with by using Windows Cmd and Windows PowerShell

Separate Pages: Adobe Acrobat Pro with JavaScript

Using Adobe Acrobat Pro Actions (formerly Batch Processing) create a custom action to separate PDF pages into separate files. Alternatively you may be able to split up PDFs with GhostScript

Acrobat JavaScript Action to split pages

/* Extract Pages to Folder */

var re = /.*\/|\.pdf$/ig;
var filename = this.path.replace(re,"");

{
    for ( var i = 0;  i < this.numPages; i++ )
    this.extractPages
     ({
        nStart: i,
        nEnd: i,
        cPath : filename + "_s" + ("000000" + (i+1)).slice (-3) + ".pdf"
    });
};

Cleanup attributes: Windows Cmd and PowerShell

I realize it is not best practice to manually brute force edit SVG or XML tags or attributes due to potential variations and should use an XML parser instead. However I had a simple issue where the stroke width on one drawing was very small, and on another the font family was being incorrectly identified, so I basically modified the previous Windows Cmd batch script to do a simple find and replace. The only changes were to the search string definitions and changing to call a PowerShell command. The PowerShell command will perform a find and replace and save the modified file with an added suffix. I did find some other references that could be better used to parse or modify the resultant SVG files if some other minor cleanup is needed to be performed.

Modifications to manually find and replace SVG XML data

:: setup file search and save string
set "_work_x1=svg"
set "_work_x2=svg"
set "_work_s2=_mod"
set "_work_file_str=*.%_work_x1%"

powershell -Command "(Get-Content '%~n1.%_work_x1%') | ForEach-Object {$_ -replace 'stroke-width:0.06', 'stroke-width:1'} | ForEach-Object {$_ -replace 'font-family:Times Roman','font-family:Times New Roman'} | Set-Content '%~n1%_work_s2%.%_work_x2%'"

Hope this might help someone

I met the same problem. I found the answer in the website:http://www.17ext.com.
First,delete the JRE System Libraries. Then,import JRE System Libraries again.

I don't know why.However it fixed my problem,hope it can help you.

You need to follow the installation instructions and not just download the files into your Python27 directory. It has to be installed in the site-packages directory properly, which the directions tell you how to do.

For ASP.NET MVC if you want to make an exception for leaving the page via submitting a particular form:

Set a form id:

@using (Html.BeginForm("Create", "MgtJob", FormMethod.Post, new { id = "createjob" }))
{
  // Your code
}



<script type="text/javascript">

  // Without submit form
   $(window).bind('beforeunload', function () {
        if ($('input').val() !== '') {
            return "It looks like you have input you haven't submitted."
        }
    });

    // this will call before submit; and it will unbind beforeunload
    $(function () {
        $("#createjob").submit(function (event) {
            $(window).unbind("beforeunload");
        });
    });

</script>

request.user.get_username() will return a string of the users email.

request.user.username will return a method.

I have seen errors on standard functions if there was a reference to a totally different library missing.

In the VBA editor launch the Compile command from the menu and then check the References dialog to see if there is anything missing and if so try to add these libraries.

In general it seems to be good practice to compile the complete VBA code and then saving the document before distribution.

If you restart service then it will work

$ service sshd restart

then check

$ ssh localhost

It will work

Use LINQ Aggregate method to convert array of integers to a comma separated string

var intArray = new []{1,2,3,4};
string concatedString = intArray.Aggregate((a, b) =>Convert.ToString(a) + "," +Convert.ToString( b));
Response.Write(concatedString);

output will be

1,2,3,4

This is one of the solution you can use if you have not .net 4 installed.

To clear only certain parameters, you can use:

[:param1, :param2, :param3].each { |k| session.delete(k) }

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".")¹ returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath() in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

• Server.MapPath(".")¹ returns D:\WebApps\shop\products
• Server.MapPath("..") returns D:\WebApps\shop
• Server.MapPath("~") returns D:\WebApps\shop
• Server.MapPath("/") returns C:\Inetpub\wwwroot
• Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward slash (/) or backward slash (\), the MapPath() returns a path as if Path was a full, virtual path.

If Path doesn't start with a slash, the MapPath() returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

1. Server.MapPath(null) and Server.MapPath("") will produce this effect too.

I have had the same problem.

In my case, since I have the original repository in my local machine, I have made a copy in a new folder without any hidden file (.git, .gitignore).

Finally I have added the .gitignore file to the new created folder.

Then I have created and added the new repository from the local path (in my case using GitHub Desktop).

The While statement will not execute until after form1 is closed - as it is outside the main message loop.

Remove it and change the first bit of code to:

private void button1_Click_1(object sender, EventArgs e)  
{  
    if (richTextBox1.Text != null)  
    {  
        this.Visible=false;
        Form2 form2 = new Form2();
        form2.show();
    }  
    else MessageBox.Show("Insert Attributes First !");  

}

This is not the best way to achieve what you are looking to do though. Instead consider the Wizard design pattern.

Alternatively you could implement a custom ApplicationContext that handles the lifetime of both forms. An example to implement a splash screen is here, which should set you on the right path.

http://www.codeproject.com/KB/cs/applicationcontextsplash.aspx?display=Print

Give your ul an id,

<ul id='yourUlId' class="subforums" style="display: none; overflow-x: visible; overflow-y: visible; ">

then do

var yourUl = document.getElementById("yourUlId");
yourUl.style.display = yourUl.style.display === 'none' ? '' : 'none';

IF you're using jQuery, this becomes:

var $yourUl = $("#yourUlId"); 
$yourUl.css("display", $yourUl.css("display") === 'none' ? '' : 'none');

Finally, you specifically said that you wanted to manipulate this css property, and not simply show or hide the underlying element. Nonetheless I'll mention that with jQuery

$("#yourUlId").toggle();

will alternate between showing or hiding this element.

@ResponseBody
@RequestMapping(value="/get-text", produces="text/plain")
public String myMethod() {
     return "Response!";
}

• You see that @ResponseBody ?

It's telling that the method returns some text and not to interpret it as a view etc.

• You see that produces="text/plain" ?

It's just a good practice as it tells what will be returned from the method :)

I've create this answer after referring above all comments & answers. This will resolve the dropdown population error even it get disabled.

Step 01

Html.DropDownList("Types", Model.Types, new {@readonly="readonly"})

Step 02 This is css pointerevent remove code.

<style type="text/css">_x000D_
    #Types {_x000D_
        pointer-events:none;_x000D_
    }_x000D_
</style>

Tested & Proven

As mentioned elsewhere, you can just iterate over the array and it will produce all results in order across all dimensions. However, if you want to know the indices as well, then how about using this - http://blogs.msdn.com/b/ericlippert/archive/2010/06/28/computing-a-cartesian-product-with-linq.aspx

then doing something like:

var dimensionLengthRanges = Enumerable.Range(0, myArray.Rank).Select(x => Enumerable.Range(0, myArray.GetLength(x)));
var indicesCombinations = dimensionLengthRanges.CartesianProduct();

foreach (var indices in indicesCombinations)
{
    Console.WriteLine("[{0}] = {1}", string.Join(",", indices), myArray.GetValue(indices.ToArray()));
}

in laravel used decimal column type for migration

$table->decimal('latitude', 10, 8);
$table->decimal('longitude', 11, 8);

for more information see available column type

"Initialized from the environment variable PYTHONPATH, plus an installation-dependent default"

-- http://docs.python.org/library/sys.html#sys.path

There is a system function called ISNUMERIC for SQL 2008 and up. An example:

SELECT myCol
FROM mTable
WHERE ISNUMERIC(myCol)<> 1;

I did a couple of quick tests and also looked further into the docs:

ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.

Which means it is fairly predictable for example

-9879210433 would pass but 987921-0433 does not. $9879210433 would pass but 9879210$433 does not.

So using this information you can weed out based on the list of valid currency symbols and + & - characters.

I know this post is very old but I could not find anything that would do this. So I finally put this together from all the forums.

This will remove All line breaks from the left and right, and removes any blank lines. Then Trim it all to look good. Alter as you see fit. I also made one that removes All Line Breaks, if interested. TY

Option 1

localhost/web is equal to localhost:80/web OR to 127.0.0.1:80/web

Option 2

localhost:8080/web is equal to localhost:8080/web OR to 127.0.0.1:8080/web

To check the size of all of the directories within a directory, you can use:

du -h --max-depth=1

In Intent, you can directly put Uri. You don't need to convert the Uri to string and convert back again to Uri.

Look at this simple approach.

// put uri to intent 
intent.setData(imageUri);

And to get Uri back from intent:

// Get Uri from Intent
Uri imageUri=getIntent().getData();

I am using Android Studio 4 developing a Fluter/Dart application. There does not seem to be a Sync project with gradle button or file menu item, there is no clean or rebuild either.

I fixed the problem by removing the .idea folder. The suggestion included removing .gradle as well, but it did not exist.

Add classpath com.google.gms:google-services:3.0.0 dependencies at project level build.gradle

Refer the sample block from project level build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {

        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

To run a command as root, and pass it the password at the command prompt, you could do it as so:

import subprocess
from getpass import getpass

ls = "sudo -S ls -al".split()
cmd = subprocess.run(
    ls, stdout=subprocess.PIPE, input=getpass("password: "), encoding="ascii",
)
print(cmd.stdout)

For your example, probably something like this:

import subprocess
from getpass import getpass

restart_apache = "sudo /usr/sbin/apache2ctl restart".split()
proc = subprocess.run(
    restart_apache,
    stdout=subprocess.PIPE,
    input=getpass("password: "),
    encoding="ascii",
)

First, have you compiled the class using the command line javac compiler? Second, it seems that your main method has an incorrect signature - it should be taking in an array of String objects, rather than just one:

public static void main(String[] args){

Once you've changed your code to take in an array of String objects, then you need to make sure that you're printing an element of the array, rather than array itself:

System.out.println(args[0])

If you want to print the whole list of command line arguments, you'd need to use a loop, e.g.

for(int i = 0; i < args.length; i++){
    System.out.print(args[i]);
}
System.out.println();

The question is quite old, but what about:

- hosts: 'localhost'
  tasks:
    - debug:
        msg: "{{ ( a | default({})).get('nested', {}).get('var','bar') }}"

It looks less cumbersome to me...

What about normal encoded white-space character?

 

There is another way to pass multiple ranges to a function, which I think feels much cleaner for the user. When you call your function in the spreadsheet you wrap each set of ranges in brackets, for example: calculateIt( (A1,A3), (B6,B9) )

The above call assumes your two Sessions are in A1 and A3, and your two Customers are in B6 and B9.

To make this work, your function needs to loop through each of the Areas in the input ranges. For example:

Function calculateIt(Sessions As Range, Customers As Range) As Single

    ' check we passed the same number of areas
    If (Sessions.Areas.Count <> Customers.Areas.Count) Then
        calculateIt = CVErr(xlErrNA)
        Exit Function
    End If

    Dim mySession, myCustomers As Range

    ' run through each area and calculate
    For a = 1 To Sessions.Areas.Count

        Set mySession = Sessions.Areas(a)
        Set myCustomers = Customers.Areas(a)

        ' calculate them...
    Next a

End Function

The nice thing is, if you have both your inputs as a contiguous range, you can call this function just as you would a normal one, e.g. calculateIt(A1:A3, B6:B9).

Hope that helps :)

Automatically entering the password for the rsync command is difficult. My simple solution to avoid the problem is to mount the folder to be backed up. Then use a local rsync command to backup the mounted folder.

mount -t cifs //server/source/ /mnt/source-tmp -o username=Username,password=password
rsync -a /mnt/source-tmp /media/destination/
umount /mnt/source-tmp

This error is coming because while calling the service, it is not getting the WSDL file of your service.

Just check whether WSDL file of your service is there--> run server and from browser run axis 2 apps on local host and check the deployed services and click on your service, then it shows WSDL file of your service.....or check the service path in your client file.

I hope it may help you to resolve the problem.

This worked for me and allow to use an headless browser, you just need to call the method passing your proxy.

def setProxy(proxy):
        options = Options()
        options.headless = True

        options.add_argument("--disable-dev-shm-usage")
        options.add_argument("--no-sandbox")
        prox = Proxy()
        prox.proxy_type = ProxyType.MANUAL
        prox.http_proxy = proxy
        prox.ssl_proxy = proxy
        capabilities = webdriver.DesiredCapabilities.CHROME
        prox.add_to_capabilities(capabilities)
        return webdriver.Chrome(desired_capabilities=capabilities, options=options, executable_path=DRIVER_PATH)

One good example of when to use something like this is with Java Simple Serial Connector, accessing serial ports. Typically you'll write something to the port, and asyncronously, on another thread, the device will respond on a SerialPortEventListener. Typically, you'll want to pause after writing to the port to wait for the response. Handling the thread locks for this scenario manually is extremely tricky, but using Countdownlatch is easy. Before you go thinking you can do it another way, be careful about race conditions you never thought of!!

Pseudocode:

CountDownLatch latch;
void writeData() { 
   latch = new CountDownLatch(1);
   serialPort.writeBytes(sb.toString().getBytes())
   try {
      latch.await(4, TimeUnit.SECONDS);
    } catch (InterruptedException e) {
   }
}
class SerialPortReader implements SerialPortEventListener {
    public void serialEvent(SerialPortEvent event) {
        if(event.isRXCHAR()){//If data is available
            byte buffer[] = serialPort.readBytes(event.getEventValue());
            latch.countDown();
         }
     }
}

You can launch any command line program using the Process class, and set the StandardOutput property of the Process instance with a stream reader you create (either based on a string or a memory location). After the process completes, you can then do whatever diff you need to on that stream.

There are 3 different ways you may wish to set this up:

1. Thrower inside of Catcher
2. Catcher inside of Thrower
3. Thrower and Catcher inside of another class in this example Test

THE WORKING GITHUB EXAMPLE I AM CITING Defaults to Option 3, to try the others simply uncomment the "Optional" code block of the class you want to be main, and set that class as the ${Main-Class} variable in the build.xml file:

4 Things needed on throwing side code:

import java.util.*;//import of java.util.event

//Declaration of the event's interface type, OR import of the interface,
//OR declared somewhere else in the package
interface ThrowListener {
    public void Catch();
}
/*_____________________________________________________________*/class Thrower {
//list of catchers & corresponding function to add/remove them in the list
    List<ThrowListener> listeners = new ArrayList<ThrowListener>();
    public void addThrowListener(ThrowListener toAdd){ listeners.add(toAdd); }
    //Set of functions that Throw Events.
        public void Throw(){ for (ThrowListener hl : listeners) hl.Catch();
            System.out.println("Something thrown");
        }
////Optional: 2 things to send events to a class that is a member of the current class
. . . go to github link to see this code . . .
}

2 Things needed in a class file to receive events from a class

/*_______________________________________________________________*/class Catcher
implements ThrowListener {//implement added to class
//Set of @Override functions that Catch Events
    @Override public void Catch() {
        System.out.println("I caught something!!");
    }
////Optional: 2 things to receive events from a class that is a member of the current class
. . . go to github link to see this code . . .
}

I think this way is better

const index = projects.findIndex(project => project.value==='jquery-ui');
projects[index].desc = "updated desc";

Whenever you see this:

try:
    y = 1 / x
except ZeroDivisionError:
    pass
else:
    return y

Or even this:

try:
    return 1 / x
except ZeroDivisionError:
    return None

Consider this instead:

import contextlib
with contextlib.suppress(ZeroDivisionError):
    return 1 / x

I am using Swift from Google Colab. Here's how to check it in Colab.

The result is 5.0-dev

You can also try this:

<a href="" onclick="if (confirm('Delete selected item?')){return true;}else{event.stopPropagation(); event.preventDefault();};" title="Link Title">
    Link Text
</a>

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

According to the sqlite docs about table creation, using the create table as select produces a new table without constraints and without primary key.

However, the documentation also says that primary keys and unique indexes are logically equivalent (see constraints section):

In most cases, UNIQUE and PRIMARY KEY constraints are implemented by creating a unique index in the database. (The exceptions are INTEGER PRIMARY KEY and PRIMARY KEYs on WITHOUT ROWID tables.) Hence, the following schemas are logically equivalent:

CREATE TABLE t1(a, b UNIQUE);

CREATE TABLE t1(a, b PRIMARY KEY);

CREATE TABLE t1(a, b);
CREATE UNIQUE INDEX t1b ON t1(b); 

So, even if you cannot alter your table definition through SQL alter syntax, you can get the same primary key effect through the use an unique index.

Also, any table (except those created without the rowid syntax) have an inner integer column known as "rowid". According to the docs, you can use this inner column to retrieve/modify record tables.

Note This answer only applies to version 2.x of Vue. Version 3 has lifted this restriction.

You have two root elements in your template.

<div class="form-group">
  ...
</div>
<div class="col-md-6">
  ...
</div>

And you need one.

<div>
    <div class="form-group">
      ...
    </div>

    <div class="col-md-6">
      ...
    </div>
</div>

Essentially in Vue you must have only one root element in your templates.

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

oldDate is not in the format of the SimpleDateFormat you are using to parse it.

Try this format: dd-MMM-yyyy - It matches what you're trying to parse.

A slight deviation from the original question however may prove useful for future people landing here wanting to DROP and CREATE an index, i.e. in a deployment script.

You can bypass the exists check simply by adding the following to your create statement:

CREATE INDEX IX_IndexName
ON dbo.TableName
WITH (DROP_EXISTING = ON);

Read more here: CREATE INDEX (Transact-SQL) - DROP_EXISTING Clause

N.B. As mentioned in the comments, the index must already exist for this clause to work without throwing an error.

That doesn't work because the second parameter should be a mapped entity and of course Integer is not a persistent class (since it doesn't have the @Entity annotation on it).

for you you should do the following:

Query q = em.createNativeQuery("select id from users where username = :username");
q.setParameter("username", "lt");
List<BigDecimal> values = q.getResultList();

or if you want to use HQL you can do something like this:

Query q = em.createQuery("select new Integer(id) from users where username = :username");
q.setParameter("username", "lt");
List<Integer> values = q.getResultList();

Regards.

You can make a .png image and then use one of the following snippets between the <head> tags of your static HTML documents:

<link rel="icon" type="image/png" href="/favicon.png"/>
<link rel="icon" type="image/png" href="https://example.com/favicon.png"/>

create table payment(
    user_id int(11),
    account int(11) not null,
    zip int(11) not null,
    dt date not null
);

insert into payment values
(1,123,55555,'2009-12-12'),
(1,123,66666,'2009-12-12'),
(1,123,77777,'2009-12-13'),
(2,456,77777,'2009-12-14'),
(2,456,77777,'2009-12-14'),
(2,789,77777,'2009-12-14'),
(2,789,77777,'2009-12-14');

select foo.user_id, foo.cnt from
(select user_id,count(account) as cnt, dt from payment group by account, dt) foo
where foo.cnt > 1;

If the code should be simple, then you probably asking for C example based on traditional BSD sockets. Solutions like boost::asio are imho quite complicated when it comes to short and simple "hello world" example.

To compile examples you mentioned you must make simple fixes, because you are compiling under C++ compiler. I'm referring to following files:
http://www.linuxhowtos.org/data/6/server.c
http://www.linuxhowtos.org/data/6/client.c
from: http://www.linuxhowtos.org/C_C++/socket.htm

1. Add following includes to both files:

   #include <cstdlib>
   #include <cstring>
   #include <unistd.h>
   

2. In client.c, change the line:

   if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

   to:

   if (connect(sockfd,(const sockaddr*)&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

As you can see in C++ an explicit cast is needed.

$('.clickable').on('click', function() {//on parent click
    $(this).removeClass('spot').addClass('grown');//use remove/add Class here because it needs to perform the same action every time, you don't want a toggle
}).children('.close_button').on('click', function(e) {//on close click
    e.stopPropagation();//stops click from triggering on parent
    $(this).parent().toggleClass('spot grown');//since this only appears when .grown is present, toggling will work great instead of add/remove Class and save some space
});

This way it's much easier to maintain.

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

I've being going round in circles with Firefox 43, El Capitan and WHM/cPanel SSL installation continually getting the Untrusted site error - I didn't buy the certificate it was handed over to me to install as the last guy walked out the door.

Although Marcelo's solution seems to be working great, you may not need to download the font at all! Just link to it remotely.

E.g the font is hosted on example.com, do

@font-face {
  font-family: "Font Name";
  font-style: normal;
  src: url(http://example.com/webfonts/font-name.woff);
}

You may easily figure out the direct url to the font by looking into css code from example.com and see how they linked the file.

I have all of my .ts files inside a src folder that is a sibling of my tsconfig.json. I was getting this error when my include looked like this (it was working before, some dependency upgrade caused the error showing up):

"include": [

],

changing it to this fixed the problem for me:

"include": [
    "**/*"
],

You could convert it to a string and use the replace method to replace the integer part with zero, then convert the result back to a number :

var number = 123.123812,
    decimals = +number.toString().replace(/^[^\.]+/,'0');

Try out this step: https://www.eclipse.org/forums/index.php/t/636348/

Go to

• Activate CDT GCC Built-in Compiler Settings
• Deactivate Use global provider shared between projects
• Add the command line argument -std=c++11.

Here's in javascript: (For example, the future date is New Year's Day)

DEMO (updates every second)

var dateFuture = new Date(new Date().getFullYear() +1, 0, 1);
var dateNow = new Date();

var seconds = Math.floor((dateFuture - (dateNow))/1000);
var minutes = Math.floor(seconds/60);
var hours = Math.floor(minutes/60);
var days = Math.floor(hours/24);

hours = hours-(days*24);
minutes = minutes-(days*24*60)-(hours*60);
seconds = seconds-(days*24*60*60)-(hours*60*60)-(minutes*60);

If you want to check if some string is present in another string, use something like String.contains

If you want to check if some pattern is present in a string, append and prepend the pattern with '.*'. The result will accept strings that contain the pattern.

Example: Suppose you have some regex a(b|c) that checks if a string matches ab or ac
.*(a(b|c)).* will check if a string contains a ab or ac.

A disadvantage of this method is that it will not give you the location of the match.

I was able to call my callback function at minimum of 250ms using audio tag and handling its ontimeupdate event. Its called 3-4 times in a second. Its better than one second lagging setTimeout

What everyone here is missing is Java's guarantee of definite assignment for final member variables.

For a class C with final member variable V, every possible execution path through every constructor of C must assign V exactly once - failing to assign V or assigning V two or more times will result in an error.

C#'s readonly keyword has no such guarantee - the compiler is more than happy to leave readonly members unassigned or allow you to assign them multiple times within a constructor.

So, final and readonly (at least with respect to member variables) are definitely not equivalent - final is much more strict.

Did you just try

$('#datebox li a').on('click', function(){
    //$('#datebox').val($(this).text());
    alert($(this).text());
});

It works for me :)

It is possible, just overwrite the Recaptcha Ajax callbacks. Working jsfiddle: http://jsfiddle.net/Vanit/Qu6kn/

You don't even need a proxy div because with the overwrites the DOM code won't execute. Call Recaptcha.reload() whenever you want to trigger the callbacks again.

function doSomething(challenge){
    $(':input[name=recaptcha_challenge_field]').val(challenge);
    $('img.recaptcha').attr('src', '//www.google.com/recaptcha/api/image?c='+challenge);
}

//Called on Recaptcha.reload()
Recaptcha.finish_reload = function(challenge,b,c){
    doSomething(challenge);
}

//Called on page load
Recaptcha.challenge_callback = function(){
    doSomething(RecaptchaState.challenge)
}

Recaptcha.create("YOUR_PUBLIC_KEY");

Python's *.py file is just a text file in which you write some lines of code. When you try to execute this file using say "python filename.py"

This command invokes Python Virtual Machine. Python Virtual Machine has 2 components: "compiler" and "interpreter". Interpreter cannot directly read the text in *.py file, so this text is first converted into a byte code which is targeted to the PVM (not hardware but PVM). PVM executes this byte code. *.pyc file is also generated, as part of running it which performs your import operation on file in shell or in some other file.

If this *.pyc file is already generated then every next time you run/execute your *.py file, system directly loads your *.pyc file which won't need any compilation(This will save you some machine cycles of processor).

Once the *.pyc file is generated, there is no need of *.py file, unless you edit it.

Put this line at the top of your source

# -*- coding: utf-8 -*-

If your editor uses a different encoding, substitute for utf-8

Then you can include utf-8 characters directly in the source

There's also the function tags, a bit more flexible:

Various browsers have various limits for maximum connections per host name; you can find the exact numbers at http://www.browserscope.org/?category=network and here is an interesting article about connection limitations from web performance expert Steve Souders http://www.stevesouders.com/blog/2008/03/20/roundup-on-parallel-connections/

The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.

There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.

The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.

This is why I like to use ALTER TABLE in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).

javascript function for client side validation (using jQuery)...

function CheckBoxRequired_ClientValidate(sender, e)
{
    e.IsValid = jQuery(".AcceptedAgreement input:checkbox").is(':checked');
}

code-behind for server side validation...

protected void CheckBoxRequired_ServerValidate(object sender, ServerValidateEventArgs e)
{
    e.IsValid = MyCheckBox.Checked;
}

ASP.Net code for the checkbox & validator...

<asp:CheckBox runat="server" ID="MyCheckBox" CssClass="AcceptedAgreement" />
<asp:CustomValidator runat="server" ID="CheckBoxRequired" EnableClientScript="true"
    OnServerValidate="CheckBoxRequired_ServerValidate"
    ClientValidationFunction="CheckBoxRequired_ClientValidate">You must select this box to proceed.</asp:CustomValidator>

and finally, in your postback - whether from a button or whatever...

if (Page.IsValid)
{
    // your code here...
}

You can set the caret position using TextBox.CaretIndex. If the only thing you need is to set the cursor at the end, you can simply pass the string's length, eg:

txtBox.CaretIndex=txtBox.Text.Length;

You need to set the caret index at the length, not length-1, because this would put the caret before the last character.

I have a large file in excel dealing with purchase and sale of mutual fund units. Number of rows in a worksheet exceeds 4000. I have no experience with VBA and would like to work with basic excel. Taking the cue from the solutions suggested above, I tried to solve the problem ( to insert blank rows automatically) in the following manner:

1. I sorted my file according to control fields
2. I added a column to the file
3. I used the "IF" function to determine when there is a change in the control data .
4. If there is a change the result will indicate "yes", otherwise "no"
5. Then I filtered the data to group all "yes" items
6. I copied mutual fund names, folio number etc (no financial data)
7. Then I removed the filter and sorted the file again. The result is a row added at the desired place. (It is not entirely a blank row, because if it is fully blank, sorting will not place the row at the desired place.)
8. After sorting, you can easily delete all values to get a completely blank row.

This method also may be tried by the readers.

Using rcParams you can show grid very easily as follows

plt.rcParams['axes.facecolor'] = 'white'
plt.rcParams['axes.edgecolor'] = 'white'
plt.rcParams['axes.grid'] = True
plt.rcParams['grid.alpha'] = 1
plt.rcParams['grid.color'] = "#cccccc"

If grid is not showing even after changing these parameters then use

plt.grid(True)

before calling

plt.show()

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

You could try:

$(SolutionDir)..\..\

I am assuming that you are asking how to remove ALL the files in the build folder or the bin folder, Rather than selecting each files separately.

You can use this command:

git rm -r -f /build\*

Make sure that you are in the parent directory of the build directory.
This command will, recursively "delete" all the files which are in the bin/ or build/ folders. By the word delete I mean that git will pretend that those files are "deleted" and those files will not be tracked. The git really marks those files to be in delete mode.

Do make sure that you have your .gitignore ready for upcoming commits.
Documentation : git rm

You could also make life easier using a wrapper, e.g. with ADODb:

$myarray=$db->GetCol("SELECT type FROM cars ".
    "WHERE owner=? and selling=0", 
    array($_SESSION['username']));

A good wrapper will do all your escaping for you too, making things easier to read.

What good is scope (private, protected) if you can just use :: to expose anything?

In Ruby, everything is exposed and everything can be modified from anywhere else.

If you're worried about the fact that classes can be changed from outside the "class definition", then Ruby probably isn't for you.

On the other hand, if you're frustrated by Java's classes being locked down, then Ruby is probably what you're looking for.

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

I use a zero-width joiner ‍

Just put that somewhere in the phone number and it works for me. Tested in BrowserStack (and Litmus for emails).

Basics

For controlling "cellpadding" in CSS, you can simply use padding on table cells. E.g. for 10px of "cellpadding":

td { 
    padding: 10px;
}

For "cellspacing", you can apply the border-spacing CSS property to your table. E.g. for 10px of "cellspacing":

table { 
    border-spacing: 10px;
    border-collapse: separate;
}

This property will even allow separate horizontal and vertical spacing, something you couldn't do with old-school "cellspacing".

Issues in IE = 7

This will work in almost all popular browsers except for Internet Explorer up through Internet Explorer 7, where you're almost out of luck. I say "almost" because these browsers still support the border-collapse property, which merges the borders of adjoining table cells. If you're trying to eliminate cellspacing (that is, cellspacing="0") then border-collapse:collapse should have the same effect: no space between table cells. This support is buggy, though, as it does not override an existing cellspacing HTML attribute on the table element.

In short: for non-Internet Explorer 5-7 browsers, border-spacing handles you. For Internet Explorer, if your situation is just right (you want 0 cellspacing and your table doesn't have it defined already), you can use border-collapse:collapse.

table { 
    border-spacing: 0;
    border-collapse: collapse;
}

Note: For a great overview of CSS properties that one can apply to tables and for which browsers, see this fantastic Quirksmode page.

In Bash if you export the variable within a subshell, using parentheses as shown, you avoid leaking the exported variables:

#!/bin/bash

TESTVARIABLE=hellohelloheloo
(
export TESTVARIABLE    
source ./test2.sh
)

The advantage here is that after you run the script from the command line, you won't see a $TESTVARIABLE leaked into your environment:

$ ./test.sh
hellohelloheloo
$ echo $TESTVARIABLE
                            #empty! no leak
$

Use SimpleDateFormat#format(Date):

String start_dt = "2011-01-01";
DateFormat formatter = new SimpleDateFormat("yyyy-MM-DD"); 
Date date = (Date)formatter.parse(start_dt);
SimpleDateFormat newFormat = new SimpleDateFormat("MM-dd-yyyy");
String finalString = newFormat.format(date);

showInLegend is a series-specific option that can hide the series from the legend. If the requirement is to hide the legends completely then it is better to use enabled: false property as shown below:

legend: { enabled: false }

More information about legend is here

Building on Sven's answer, I found using collections.OrderedDict like so helped me accomplish what you want plus allow me to add more items to the dict:

import collections

x=[1,2,20,6,210]
z=collections.OrderedDict.fromkeys(x)
z
OrderedDict([(1, None), (2, None), (20, None), (6, None), (210, None)])

If you want to add items but still treat it like a set you can just do:

z['nextitem']=None

And you can perform an operation like z.keys() on the dict and get the set:

z.keys()
[1, 2, 20, 6, 210]

you can make custom style for switch widget that use color accent as a default when do custom style for it

<style name="switchStyle" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimary</item>    <!-- set your color -->
</style>    

I guess you passed a List or an Array to the Adapter. If you keep the instance of this added collection, you can do a

collection.clear();
listview.getAdapter().notifyDataSetChanged();

this'll work only if you instantiated the adapter with collection and it's the same instance.

Also, depending on the Adapter you extended, you may not be able to do this. SimpleAdapter is used for static data, thus it can't be updated after creation.

PS. not all Adapters have a clear() method. ArrayAdapter does, but ListAdapter or SimpleAdapter don't

I suggest you use CSS instead, seems like you're going to repeat those lines later on. But to answer your question:

<html>
  <head>
  <style type="text/css">
    td.randname {
        padding-left: 5px;
        padding-bottom:3px;
        font-size:35px;
    }
  </style>
  </head>
  <body>
  <table>
  <tr>
  <td class="randname"> <b>Datum:</b><br/>
                            November 2010 </td></tr>
                            </table>
  </body>
</html>

Since FFT is symmetric over it's centre, half the values are just enough.

import numpy as np
import matplotlib.pyplot as plt

fs = 30.0
t = np.arange(0,10,1/fs)
x = np.cos(2*np.pi*10*t)

xF = np.fft.fft(x)
N = len(xF)
xF = xF[0:N/2]
fr = np.linspace(0,fs/2,N/2)

plt.ion()
plt.plot(fr,abs(xF)**2)

I had this issue because a method I was trying to implement required a std::unique_ptr<Queue>(myQueue) as a parameter, but the Queue class is abstract. I solved that by using a QueuePtr(myQueue) constructor like so:

using QueuePtr = std::unique_ptr<Queue>;

and used that in the parameter list instead. This fixes it because the initializer tries to create a copy of Queue when you make a std::unique_ptr of its type, which can't happen.

You need the following permissions in your manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

I see, I'm 10 years too late to the party. I was facing the situation, where from some property I can receive either a file name or a full file path. If there is no path provided, I have to check the file-existence by attaching a "global" directory-path provided by another property.

In my case

var isFileName = System.IO.Path.GetFileName (str) == str;

did the trick. Ok, it's not magic, but perhaps this could save someone a few minutes of figuring out. Since this is merely a string-parsing, so Dir-names with dots may give false positives...

This seems to be the best solution I’ve found to this problem, as long as your browser supports the ::before pseudo element: CSS-Tricks: Centering in the Unknown.

It doesn’t require any extra markup and seems to work extremely well. I couldn’t use the display: table method because table elements don’t obey the max-height property.

In CSS 1 and CSS 2 specifications, padding was available for all elements including <tr>. Yet support of padding for table-row (<tr>) has been removed in CSS 2.1 and CSS 3 specifications. I have never found the reason behind this annoying change which also affect margin property and a few other table elements (header, footer, and columns).

Update: in Feb 2015, this thread on the [email protected] mailing list discussed about adding support of padding and border for table-row. This would apply the standard box model also to table-row and table-column elements. It would permit such examples. The thread seems to suggest that table-row padding support never existed in CSS standards because it would have complicated layout engines. In the 30 September 2014 Editor's Draft of CSS basic box model, padding and border properties exist for all elements including table-row and table-column elements. If it eventually becomes a W3C recommendation, your html+css example may work as intended in browsers at last.

You have probably installed the 32bit drivers will the job is running in 64bit. More info: http://microsoft-ssis.blogspot.com/2014/02/connecting-to-excel-xlsx-in-ssis.html

yes you need to call repaint(); revalidate(); when you call removeAll() then you have to call repaint() and revalidate()

Duplicating my answer from here because I spent some time looking for this:

This is now possible in newer versions of Jenkins, you can do something like this:

#!/usr/bin/env groovy

properties([
  parameters([string(name: 'foo', defaultValue: 'bar', description: 'Fails job if not bar (unstable if bar)')]),
])


stage('Stage 1') {
  node('parent'){
    def ret = sh(
      returnStatus: true, // This is the key bit!
      script: '''if [ "$foo" = bar ]; then exit 2; else exit 1; fi'''
    )
    // ret can be any number/range, does not have to be 2.
    if (ret == 2) {
      currentBuild.result = 'UNSTABLE'
    } else if (ret != 0) {
      currentBuild.result = 'FAILURE'
      // If you do not manually error the status will be set to "failed", but the
      // pipeline will still run the next stage.
      error("Stage 1 failed with exit code ${ret}")
    }
  }
}

The Pipeline Syntax generator shows you this in the advanced tab:

There are many ways to hide all elements which has certain class in javascript one way is to using for loop but here i want to show you other ways to doing it.

1.forEach and querySelectorAll('.classname')

document.querySelectorAll('.classname').forEach(function(el) {
   el.style.display = 'none';
});

2.for...of with getElementsByClassName

for (let element of document.getElementsByClassName("classname")){
   element.style.display="none";
}

3.Array.protoype.forEach getElementsByClassName

Array.prototype.forEach.call(document.getElementsByClassName("classname"), function(el) {
    // Do something amazing below
    el.style.display = 'none';
});

4.[ ].forEach and getElementsByClassName

[].forEach.call(document.getElementsByClassName("classname"), function (el) {
    el.style.display = 'none';
});

i have shown some of the possible ways, there are also more ways to do it, but from above list you can Pick whichever suits and easy for you.

Note: all above methods are supported in modern browsers but may be some of them will not work in old age browsers like internet explorer.
