Try with below logic

driver.get("http://www.labmultis.info/jpecka.portal-exdrazby/index.php?c1=2&a=s&aa=&ta=1");

List<WebElement> allElements=driver.findElements(By.cssSelector(".list.list-categories li"));

for(WebElement ele :allElements) {
    System.out.println("Name + Number===>"+ele.getText());
    String s=ele.getText();
    s=s.substring(s.indexOf("(")+1, s.indexOf(")"));
    System.out.println("Number==>"+s);
}

====Output======

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

'' encloses single char, while "" encloses a String.

Change

y = 'hello';

-->

y = "hello";

You can do following

FIDDLE

<div id="circle"></div>

CSS

#circle {
    width: 100px;
    height: 100px;
    background: red;
    -moz-border-radius: 50px;
    -webkit-border-radius: 50px;
    border-radius: 50px;
}

The answers by Brandon and fatbotdesigns are both correct, but having implemented the Google docs preview, we found multiple .docx files that couldn't be handled by Google. Switched to the MS Office Online preview and works likes a charm.

My recommendation would be to use the MS Office Preview URL over Google's.

ws2s project is aimed at bring socket to browser-side js. It is a websocket server which transform websocket to socket.

ws2s schematic diagram

code sample:

var socket = new WS2S("wss://ws2s.feling.io/").newSocket()

socket.onReady = () => {
  socket.connect("feling.io", 80)
  socket.send("GET / HTTP/1.1\r\nHost: feling.io\r\nConnection: close\r\n\r\n")
}

socket.onRecv = (data) => {
  console.log('onRecv', data)
}

Just add these two lines to $(document).ready in JS as follow:

$(document).ready(function () {
 $("div.sidebar nav a").removeClass("active");
        $('nav a[href$="'+ window.location.pathname.split("?")[0] +'"]').addClass('active');
});

it is better to use the dollar sign ($) (End with)

$('nav a[href$

instead of (^) (Start with)

$('nav a[href^

because, if you use the (^) sign and you have nested URLs in the navigation menu, (e.g "/account" and "/account/roles")

It will active both of them.

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

According to this helpful list of operators [an operator can be thought of as a mathematical expression] found here, you can tell the batch compiler that you are manipulating variables instead of fixed numbers by using the += operator instead of the + operator.

Hope I Helped!

You are prematurely optimizing. Also, you should really put some thought into whether GET should be used for stuff you're POST-ing, for security reasons.

Please don't mess with view.tintColor or extensions, but simply use this:

UIColor.systemBlue

Construct your client as such

HostnameVerifier hostnameVerifier = HttpsURLConnection.getDefaultHostnameVerifier();
ClientConfig config = new DefaultClientConfig();
SSLContext ctx = SSLContext.getInstance("SSL");
ctx.init(null, myTrustManager, null);
config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new HTTPSProperties(hostnameVerifier, ctx));
Client client = Client.create(config);

For information on setting up your certs, see this nicely answered SO question: Using HTTPS with REST in Java

I think of it as a large array of binary data. The usability of BLOB follows immediately from the limited bandwidth of the DB interface, it is not determined by the DB storage mechanisms. No matter how you store the large piece of data, the only way to store and retrieve is the narrow database interface. The database is a bottleneck of the system. Why to use it as a file server, which can easily be distributed? Normally you do not want to download the BLOB. You just want the DB to store your BLOB urls. Deposite the BLOBs on a separate file server. Then, you reliefe the precious DB connection and provide unlimited bandwidth for large objects. This creates some issue of coherence though.

You just need to use these commands

sudo rm -rf /Library/Java/*
sudo rm -rf /Library/PreferencePanes/Java*
sudo rm -rf /Library/Internet\ Plug-Ins/Java*

Angular 6

You can pass in parameters needed for get call by using params:

this.httpClient.get<any>(url, { params: x });

where x = { property: "123" }.

As for the api function that logs "123":

router.get('/example', (req, res) => {
    console.log(req.query.property);
})

In your case, to fast-forward, run:

$ git merge --ff-only origin/master

This uses the --ff-only option of git merge, as the question specifically asks for "fast-forward".

Here is an excerpt from git-merge(1) that shows more fast-forward options:

--ff, --no-ff, --ff-only
    Specifies how a merge is handled when the merged-in history is already a descendant of the current history.  --ff is the default unless merging an annotated
    (and possibly signed) tag that is not stored in its natural place in the refs/tags/ hierarchy, in which case --no-ff is assumed.

    With --ff, when possible resolve the merge as a fast-forward (only update the branch pointer to match the merged branch; do not create a merge commit). When
    not possible (when the merged-in history is not a descendant of the current history), create a merge commit.

    With --no-ff, create a merge commit in all cases, even when the merge could instead be resolved as a fast-forward.

    With --ff-only, resolve the merge as a fast-forward when possible. When not possible, refuse to merge and exit with a non-zero status.

I fast-forward often enough that it warranted an alias:

$ git config --global alias.ff 'merge --ff-only @{upstream}'

Now I can run this to fast-forward:

$ git ff

Like this:

background-image:url(https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Dore_woodcut_Divine_Comedy_01.jpg/481px-Dore_woodcut_Divine_Comedy_01.jpg);
background-repeat:no-repeat;
background-position: center;
background-size: cover;

background-repeat:no-repeat;_x000D_
background-position: center;_x000D_
background-size: cover;_x000D_
}

Make your variable nullable. Like:

Color? color = null;

or

Nullable<Color> color = null;

Another info: If you want use a Route Constraint, imagine that you want force that parameter has int datatype, then you need use this syntax:

[Route("v1/location/**{deviceOrAppid:int?}**", Name = "AddNewLocation")]

The ? character is put always before the last } character

Change .img-responsive inside bootstrap.css to the following:

.img-responsive {
    display: block;
    max-width: 100%;
    width: 100%;
    height: auto;
}

For some reason adding width: 100% to the mix makes img-responsive work.

You can use the modulus operator like this, no need for jQuery. Just replace the alerts with your code.

var x = 2;
if (x % 2 == 0)
{
  alert('even');
}
else
{
  alert('odd')
}

If you don't know the index beforehand here is a function that will work

def reverse_index(l, index):
    try:
        l.pop(index)
        return l
    except IndexError:
        return False

Based on your replies to everyone else, something like this is what you're looking for.

string file = @"C:\file.txt";
string strToProcess = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
string[] lines = strToProcess.Split(new char[] { '@' }, StringSplitOptions.RemoveEmptyEntries);

using (StreamWriter writer = new StreamWriter(file))
{
    foreach (string line in lines)
    {
        writer.WriteLine(line + "@");
    }
}

The DECLARE GLOBAL TEMPORARY TABLE statement defines a temporary table for the current connection.

These tables do not reside in the system catalogs and are not persistent.

Temporary tables exist only during the connection that declared them and cannot be referenced outside of that connection.

When the connection closes, the rows of the table are deleted, and the in-memory description of the temporary table is dropped.

For your reference http://docs.oracle.com/javadb/10.6.2.1/ref/rrefdeclaretemptable.html

<select id="select">_x000D_
    <optgroup label="select one option">_x000D_
        <option>one</option>  _x000D_
        <option>two</option>  _x000D_
        <option>three</option>  _x000D_
        <option>four</option>  _x000D_
        <option>five</option>_x000D_
    </optgroup>_x000D_
</select>

It all sounded like a lot of hard work to me, when optgroup gives you what you need - at least I think it does.

i have fixed the issue by just downloading the android command line tool from https://www.visualsvn.com/downloads/ download apache comand line tool unzip it on drive go to your android settings/version control/subversion and make sure only command line option is enable set the path of svn.exe as shown below C:\Users\viratsinh.parmar\Apace SVN client\Apache-Subversion-1.8.13\bin\svn.exe

now in your android studio update the project , you will be able to commit now. you can contact me on [email protected]

Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.

You supply a function that takes a date and returns a boolean array:

"$(".selector").datepicker({ beforeShowDay: nationalDays}) 
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], 
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']]; 
function nationalDays(date) { 
    for (i = 0; i < natDays.length; i++) { 
      if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == 
natDays[i][1]) { 
        return [false, natDays[i][2] + '_day']; 
      } 
    } 
  return [true, '']; 
} 

You can use below code for h2 and MySQl

    @Query(value = "SELECT req.CREATED_AT createdAt, req.CREATED_BY createdBy,req.APP_ID appId,req.NOTE_ID noteId,req.MODEL model FROM SUMBITED_REQUESTS  req inner join NOTE note where req.NOTE_ID=note.ID and note.CREATED_BY= :userId "
        ,
         countQuery = "SELECT count(*) FROM SUMBITED_REQUESTS req inner join NOTE note WHERE req.NOTE_ID=note.ID and note.CREATED_BY=:userId",
        nativeQuery = true)
Page<UserRequestsDataMapper> getAllRequestForCreator(@Param("userId") String userId,Pageable pageable);

I liked PostMan, it was the main reason why I kept using Chrome, now I'm good with HttpRequester

The URL file://[servername]/[sharename] should open an explorer window to the shared folder on the network.

I have not used BeuatifulSoup but maybe the following can help in some tiny way.

import re
import urllib2
stuff = urllib2.urlopen(your_url_goes_here).read()  # stuff will contain the *entire* page

# Replace the string Python with your desired regex
results = re.findall('(Python)',stuff)

for i in results:
    print i

I'm not suggesting this is a replacement but maybe you can glean some value in the concept until a direct answer comes along.

Maybe you'll also want decimal separator? Here is a function I just made:

function formatFloat(num,casasDec,sepDecimal,sepMilhar) {
    if (num < 0)
    {
        num = -num;
        sinal = -1;
    } else
        sinal = 1;
    var resposta = "";
    var part = "";
    if (num != Math.floor(num)) // decimal values present
    {
        part = Math.round((num-Math.floor(num))*Math.pow(10,casasDec)).toString(); // transforms decimal part into integer (rounded)
        while (part.length < casasDec)
            part = '0'+part;
        if (casasDec > 0)
        {
            resposta = sepDecimal+part;
            num = Math.floor(num);
        } else
            num = Math.round(num);
    } // end of decimal part
    while (num > 0) // integer part
    {
        part = (num - Math.floor(num/1000)*1000).toString(); // part = three less significant digits
        num = Math.floor(num/1000);
        if (num > 0)
            while (part.length < 3) // 123.023.123  if sepMilhar = '.'
                part = '0'+part; // 023
        resposta = part+resposta;
        if (num > 0)
            resposta = sepMilhar+resposta;
    }
    if (sinal < 0)
        resposta = '-'+resposta;
    return resposta;
}

jQuery also has an excellent implementation that's incredibly easy to use. Here's how you could implement this functionality across browsers:

$(document).keypress(function(e){
    var checkWebkitandIE=(e.which==26 ? 1 : 0);
    var checkMoz=(e.which==122 && e.ctrlKey ? 1 : 0);

    if (checkWebkitandIE || checkMoz) $("body").append("<p>ctrl+z detected!</p>");
});

Tested in IE7,Firefox 3.6.3 & Chrome 4.1.249.1064

Another way of doing this is to use the keydown event and track the event.keyCode. However, since jQuery normalizes keyCode and charCode using event.which, their spec recommends using event.which in a variety of situations:

$(document).keydown(function(e){
if (e.keyCode==90 && e.ctrlKey)
    $("body").append("<p>ctrl+z detected!</p>");
});

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

Using the latest Markdown, you should be able to use the following syntax:

[](){:name='anchorName'}

This should create the following HTML:

<a name="anchorName"></a>

If you wanted the anchor to have text, simply add the anchor text within the square brackets:

[Some Text](){:name='anchorName'}

A couple years late, but here is a solution that retrieves both inline styling and external styling:

function css(a) {
    var sheets = document.styleSheets, o = {};
    for (var i in sheets) {
        var rules = sheets[i].rules || sheets[i].cssRules;
        for (var r in rules) {
            if (a.is(rules[r].selectorText)) {
                o = $.extend(o, css2json(rules[r].style), css2json(a.attr('style')));
            }
        }
    }
    return o;
}

function css2json(css) {
    var s = {};
    if (!css) return s;
    if (css instanceof CSSStyleDeclaration) {
        for (var i in css) {
            if ((css[i]).toLowerCase) {
                s[(css[i]).toLowerCase()] = (css[css[i]]);
            }
        }
    } else if (typeof css == "string") {
        css = css.split("; ");
        for (var i in css) {
            var l = css[i].split(": ");
            s[l[0].toLowerCase()] = (l[1]);
        }
    }
    return s;
}

Pass a jQuery object into css() and it will return an object, which you can then plug back into jQuery's $().css(), ex:

var style = css($("#elementToGetAllCSS"));
$("#elementToPutStyleInto").css(style);

When you run Python interactively the local __name__ variable is assigned a value of __main__. Likewise, when you execute a Python module from the command line, rather than importing it into another module, its __name__ attribute is assigned a value of __main__, rather than the actual name of the module. In this way, modules can look at their own __name__ value to determine for themselves how they are being used, whether as support for another program or as the main application executed from the command line. Thus, the following idiom is quite common in Python modules:

if __name__ == '__main__':
    # Do something appropriate here, like calling a
    # main() function defined elsewhere in this module.
    main()
else:
    # Do nothing. This module has been imported by another
    # module that wants to make use of the functions,
    # classes and other useful bits it has defined.

Htaccess is a configuration file of apache which is used to make changes in the configuration on a directory basis. Htaccess file is used to do changes in functions and features of the apache server. Htaccess is used to rewrite the URL. It is used to make site address protected. Also to restrict IP addresses so on particular IP address site will not be opened

I had a similar problem, simply running a trivial ruby script that just required the gem i wanted...got that error message. When I changed the incantation from:

Seemed to work.

could you try doing JSON.stringify(obj);

Like this

 var stringify = JSON.stringify(obj);
fs.writeFileSync('./data.json', stringify , 'utf-8'); 

simply change <div> to <tbody>

  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>

In the service project do the following:

1. In the solution explorer double click your services .cs file. It should bring up a screen that is all gray and talks about dragging stuff from the toolbox.
2. Then right click on the gray area and select add installer. This will add an installer project file to your project.
3. Then you will have 2 components on the design view of the ProjectInstaller.cs (serviceProcessInstaller1 and serviceInstaller1). You should then setup the properties as you need such as service name and user that it should run as.

Now you need to make a setup project. The best thing to do is use the setup wizard.

1. Right click on your solution and add a new project: Add > New Project > Setup and Deployment Projects > Setup Wizard

   a. This could vary slightly for different versions of Visual Studio. b. Visual Studio 2010 it is located in: Install Templates > Other Project Types > Setup and Deployment > Visual Studio Installer

2. On the second step select "Create a Setup for a Windows Application."

3. On the 3rd step, select "Primary output from..."

4. Click through to Finish.

Next edit your installer to make sure the correct output is included.

1. Right click on the setup project in your Solution Explorer.
2. Select View > Custom Actions. (In VS2008 it might be View > Editor > Custom Actions)
3. Right-click on the Install action in the Custom Actions tree and select 'Add Custom Action...'
4. In the "Select Item in Project" dialog, select Application Folder and click OK.
5. Click OK to select "Primary output from..." option. A new node should be created.
6. Repeat steps 4 - 5 for commit, rollback and uninstall actions.

You can edit the installer output name by right clicking the Installer project in your solution and select Properties. Change the 'Output file name:' to whatever you want. By selecting the installer project as well and looking at the properties windows, you can edit the Product Name, Title, Manufacturer, etc...

Next build your installer and it will produce an MSI and a setup.exe. Choose whichever you want to use to deploy your service.

$("selector").css("border-bottom-color", "#fff");

1. construct your jQuery object which provides callable methods first. In this case, say you got an #mydiv, then $("#mydiv")
2. call the .css() method provided by jQuery to modify specified object's css property values.

This would be the Unicode solution

String s = "A função, Ãugent";
String r = s.replaceAll("\\P{InBasic_Latin}", "");

\p{InBasic_Latin} is the Unicode block that contains all letters in the Unicode range U+0000..U+007F (see regular-expression.info)

\P{InBasic_Latin} is the negated \p{InBasic_Latin}

This is because of the combination of two things:

• tsconfig not having any files section. From http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

  If no "files" property is present in a tsconfig.json, the compiler defaults to including all files in the containing directory and subdirectories. When a "files" property is specified, only those files are included.

• Including typescript as an npm dependency : node_modules/typescript/ This means that all of typescript gets included .... there is an implicitly included lib.d.ts in your project anyways (http://basarat.gitbook.io/typescript/content/docs/types/lib.d.ts.html) and its conflicting with the one that ships with the NPM version of typescript.

Fix

Either list files or include explicitly https://basarat.gitbook.io/typescript/docs/project/files.html

You should have a look into JSON-P - that was a perfect solution for me when I had that problem:

https://en.wikipedia.org/wiki/JSONP

You basically define a javascript file that loads all your data and another javascript file that processes and displays it. That gets rid of the ugly scrollbar of iframes.

While my answer is not as performant as others, my focus was more on not hard coding in base numbers and allowing the program to figure out the rest.
For example...
Instead of:
number = [1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1],
numeral = ['M', 'CM', 'D', 'CD', 'C', 'XC', 'L', 'XL', 'X', 'IX', 'V', 'IV', 'I']

I used:

base = ['I', 'X', 'C', 'M']; pivot = ['V', 'L', 'D'];

function basicRomanNumerals(num){
let base = ['I', 'X', 'C', 'M'];
let pivot = ['V', 'L', 'D'];
return String(num).split('').reverse().map(function(num, idx){
    let distance = +num - 5;
    let is1AwayFromNext = Math.abs(+num - 10) === 1;
    if(Math.abs(distance)=== 1 || is1AwayFromNext){
        if(is1AwayFromNext){
            return base[idx]+""+base[idx+1];
        }else if ( distance < 0 ){
            return base[idx]+""+pivot[idx];
        }else{
            return pivot[idx]+""+base[idx];
        }
    }else if(distance === 0){
        return pivot[idx];
    }else if(distance > 1){
        return pivot[idx]+""+base[idx].repeat(+num-5);
    }else{
        return base[idx].repeat(+num);
    }
}).reverse().join('');

A working example:

$qb = $this->createQueryBuilder('a');
$query=$qb->getQuery();
// SHOW SQL: 
echo $query->getSQL(); 
// Show Parameters: 
echo $query->getParameters();

You can also do it with print instead of write:

with open('test.txt', 'a') as f:
    print('appended text', file=f)

If test.txt doesn't exist, it will be created...

Quentin's answer clearly states that i tag should not be used to define icons.

But, Holly suggested that span has no meaning in itself and voted in favor of i instead of span tag.

Few suggested to use img as it's semantic and contains alt tag. But, we should not also use img because even empty src sends a request to server. Read here

I think, the correct way would be,

<span class="icon-fb" role="img" aria-label="facebook"></span>

This solves the issue of no alt tag in span and makes it accessible to vision-impaired users. It's semantic and not misusing ( hacking ) any tag.

next:

select * from foo where id = (select min(id) from foo where id > 4)

previous:

select * from foo where id = (select max(id) from foo where id < 4)

Clean and Simple:

$('#signup').submit(function(event) {

      alert(this.action);
});

You are trying to concatenate a string and an integer.
You need to cast @ID as a string.
try:

SET @sql=@sql+' AND Emp_Id_Pk=' + CAST(@ID AS NVARCHAR(10))

You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.

Most common way:

console.log(object);

However I must mention JSON.stringify which is useful to dump variables in non-browser scripts:

console.log( JSON.stringify(object) );

The JSON.stringify function also supports built-in prettification as pointed out by Simon Zyx.

Example:

var obj = {x: 1, y: 2, z: 3};

console.log( JSON.stringify(obj, null, 2) ); // spacing level = 2

The above snippet will print:

{
  "x": 1,
  "y": 2,
  "z": 3
}

On caniuse.com you can view the browsers that support natively the JSON.stringify function: http://caniuse.com/json

You can also use the Douglas Crockford library to add JSON.stringify support on old browsers: https://github.com/douglascrockford/JSON-js

Docs for JSON.stringify: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

I hope this helps :-)

I hope this code will work fine. You can have a try.

// Include this.                
using System.Net.Mail;

string fromAddress = "[email protected]";
string mailPassword = "*****";       // Mail id password from where mail will be sent.
string messageBody = "Write the body of the message here.";


// Create smtp connection.
SmtpClient client = new SmtpClient();
client.Port = 587;//outgoing port for the mail.
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential(fromAddress, mailPassword);


// Fill the mail form.
var send_mail = new MailMessage();

send_mail.IsBodyHtml = true;
//address from where mail will be sent.
send_mail.From = new MailAddress("[email protected]");
//address to which mail will be sent.           
send_mail.To.Add(new MailAddress("[email protected]");
//subject of the mail.
send_mail.Subject = "put any subject here";

send_mail.Body = messageBody;
client.Send(send_mail);

In Windows, with Wireshark 2.0.4, running as Administrator did not solve this for me. What did was restarting the NetGroup Packet Filter Driver (npf) service:

1. Open a Command Prompt with administrative privileges.
2. Execute the command sc query npf and verify if the service is running.
3. Execute the command sc stop npf followed by the command sc start npf.
4. Open WireShark and press F5.

First Program with comments

#include <stdio.h>

int main(){
    int *ptr;             //Create a pointer that points to random memory address

    *ptr = 20;            //Dereference that pointer, 
                          // and assign a value to random memory address.
                          //Depending on external (not inside your program) state
                          // this will either crash or SILENTLY CORRUPT another 
                          // data structure in your program.  

    printf("%d", *ptr);   //Print contents of same random memory address
                          // May or may not crash, depending on who owns this address

    return 0;             
}

Second Program with comments

#include <stdio.h>

int main(){
    int *ptr;              //Create pointer to random memory address

    int q = 50;            //Create local variable with contents int 50

    ptr = &q;              //Update address targeted by above created pointer to point
                           // to local variable your program properly created

    printf("%d", *ptr);    //Happily print the contents of said local variable (q)
    return 0;
}

The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.

Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.

“In computer programming, a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code. This allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.” - Wikipedia

Callback in C using Function Pointer

In C, callback is implemented using Function Pointer. Function Pointer - as the name suggests, is a pointer to a function.

For example, int (*ptrFunc) ();

Here, ptrFunc is a pointer to a function that takes no arguments and returns an integer. DO NOT forget to put in the parenthesis, otherwise the compiler will assume that ptrFunc is a normal function name, which takes nothing and returns a pointer to an integer.

Here is some code to demonstrate the function pointer.

#include<stdio.h>
int func(int, int);
int main(void)
{
    int result1,result2;
    /* declaring a pointer to a function which takes
       two int arguments and returns an integer as result */
    int (*ptrFunc)(int,int);

    /* assigning ptrFunc to func's address */                    
    ptrFunc=func;

    /* calling func() through explicit dereference */
    result1 = (*ptrFunc)(10,20);

    /* calling func() through implicit dereference */        
    result2 = ptrFunc(10,20);            
    printf("result1 = %d result2 = %d\n",result1,result2);
    return 0;
}

int func(int x, int y)
{
    return x+y;
}

Now let us try to understand the concept of Callback in C using function pointer.

The complete program has three files: callback.c, reg_callback.h and reg_callback.c.

/* callback.c */
#include<stdio.h>
#include"reg_callback.h"

/* callback function definition goes here */
void my_callback(void)
{
    printf("inside my_callback\n");
}

int main(void)
{
    /* initialize function pointer to
    my_callback */
    callback ptr_my_callback=my_callback;                        
    printf("This is a program demonstrating function callback\n");
    /* register our callback function */
    register_callback(ptr_my_callback);                          
    printf("back inside main program\n");
    return 0;
}

/* reg_callback.h */
typedef void (*callback)(void);
void register_callback(callback ptr_reg_callback);


/* reg_callback.c */
#include<stdio.h>
#include"reg_callback.h"

/* registration goes here */
void register_callback(callback ptr_reg_callback)
{
    printf("inside register_callback\n");
    /* calling our callback function my_callback */
    (*ptr_reg_callback)();                               
}

If we run this program, the output will be

This is a program demonstrating function callback inside register_callback inside my_callback back inside main program

The higher layer function calls a lower layer function as a normal call and the callback mechanism allows the lower layer function to call the higher layer function through a pointer to a callback function.

Callback in Java Using Interface

Java does not have the concept of function pointer It implements Callback mechanism through its Interface mechanism Here instead of a function pointer, we declare an Interface having a method which will be called when the callee finishes its task

Let me demonstrate it through an example:

The Callback Interface

public interface Callback
{
    public void notify(Result result);
}

The Caller or the Higher Level Class

public Class Caller implements Callback
{
Callee ce = new Callee(this); //pass self to the callee

//Other functionality
//Call the Asynctask
ce.doAsynctask();

public void notify(Result result){
//Got the result after the callee has finished the task
//Can do whatever i want with the result
}
}

The Callee or the lower layer function

public Class Callee {
Callback cb;
Callee(Callback cb){
this.cb = cb;
}

doAsynctask(){
//do the long running task
//get the result
cb.notify(result);//after the task is completed, notify the caller
}
}

Callback Using EventListener pattern

• List item

This pattern is used to notify 0 to n numbers of Observers/Listeners that a particular task has finished

• List item

The difference between Callback mechanism and EventListener/Observer mechanism is that in callback, the callee notifies the single caller, whereas in Eventlisener/Observer, the callee can notify anyone who is interested in that event (the notification may go to some other parts of the application which has not triggered the task)

Let me explain it through an example.

The Event Interface

public interface Events {

public void clickEvent();
public void longClickEvent();
}

Class Widget

package com.som_itsolutions.training.java.exampleeventlistener;

import java.util.ArrayList;
import java.util.Iterator;

public class Widget implements Events{

    ArrayList<OnClickEventListener> mClickEventListener = new ArrayList<OnClickEventListener>(); 
    ArrayList<OnLongClickEventListener> mLongClickEventListener = new ArrayList<OnLongClickEventListener>();

    @Override
    public void clickEvent() {
        // TODO Auto-generated method stub
        Iterator<OnClickEventListener> it = mClickEventListener.iterator();
                while(it.hasNext()){
                    OnClickEventListener li = it.next();
                    li.onClick(this);
                }   
    }
    @Override
    public void longClickEvent() {
        // TODO Auto-generated method stub
        Iterator<OnLongClickEventListener> it = mLongClickEventListener.iterator();
        while(it.hasNext()){
            OnLongClickEventListener li = it.next();
            li.onLongClick(this);
        }

    }

    public interface OnClickEventListener
    {
        public void onClick (Widget source);
    }

    public interface OnLongClickEventListener
    {
        public void onLongClick (Widget source);
    }

    public void setOnClickEventListner(OnClickEventListener li){
        mClickEventListener.add(li);
    }
    public void setOnLongClickEventListner(OnLongClickEventListener li){
        mLongClickEventListener.add(li);
    }
}

Class Button

public class Button extends Widget{
private String mButtonText;
public Button (){
} 
public String getButtonText() {
return mButtonText;
}
public void setButtonText(String buttonText) {
this.mButtonText = buttonText;
}
}

Class Checkbox

public class CheckBox extends Widget{
private boolean checked;
public CheckBox() {
checked = false;
}
public boolean isChecked(){
return (checked == true);
}
public void setCheck(boolean checked){
this.checked = checked;
}
}

Activity Class

package com.som_itsolutions.training.java.exampleeventlistener;

public class Activity implements Widget.OnClickEventListener
{
    public Button mButton;
    public CheckBox mCheckBox;
    private static Activity mActivityHandler;
    public static Activity getActivityHandle(){
        return mActivityHandler;
    }
    public Activity ()
    {
        mActivityHandler = this;
        mButton = new Button();
        mButton.setOnClickEventListner(this);
        mCheckBox = new CheckBox();
        mCheckBox.setOnClickEventListner(this);
        } 
    public void onClick (Widget source)
    {
        if(source == mButton){
            mButton.setButtonText("Thank you for clicking me...");
            System.out.println(((Button) mButton).getButtonText());
        }
        if(source == mCheckBox){
            if(mCheckBox.isChecked()==false){
                mCheckBox.setCheck(true);
                System.out.println("The checkbox is checked...");
            }
            else{
                mCheckBox.setCheck(false);
                System.out.println("The checkbox is not checked...");
            }       
        }
    }
    public void doSomeWork(Widget source){
        source.clickEvent();
    }   
}

Other Class

public class OtherClass implements Widget.OnClickEventListener{
Button mButton;
public OtherClass(){
mButton = Activity.getActivityHandle().mButton;
mButton.setOnClickEventListner(this);//interested in the click event                        //of the button
}
@Override
public void onClick(Widget source) {
if(source == mButton){
System.out.println("Other Class has also received the event notification...");
}
}

Main Class

public class Main {
public static void main(String[] args) {
// TODO Auto-generated method stub
Activity a = new Activity();
OtherClass o = new OtherClass();
a.doSomeWork(a.mButton);
a.doSomeWork(a.mCheckBox);
}
}

As you can see from the above code, that we have an interface called events which basically lists all the events that may happen for our application. The Widget class is the base class for all the UI components like Button, Checkbox. These UI components are the objects that actually receive the events from the framework code. Widget class implements the Events interface and also it has two nested interfaces namely OnClickEventListener & OnLongClickEventListener

These two interfaces are responsible for listening to events that may occur on the Widget derived UI components like Button or Checkbox. So if we compare this example with the earlier Callback example using Java Interface, these two interfaces work as the Callback interface. So the higher level code (Here Activity) implements these two interfaces. And whenever an event occurs to a widget, the higher level code (or the method of these interfaces implemented in the higher level code, which is here Activity) will be called.

Now let me discuss the basic difference between Callback and Eventlistener pattern. As we have mentioned that using Callback, the Callee can notify only a single Caller. But in the case of EventListener pattern, any other part or class of the Application can register for the events that may occur on the Button or Checkbox. The example of this kind of class is the OtherClass. If you see the code of the OtherClass, you will find that it has registered itself as a listener to the ClickEvent that may occur in the Button defined in the Activity. Interesting part is that, besides the Activity ( the Caller), this OtherClass will also be notified whenever the click event occurs on the Button.

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

First of all, note you are not using the variable correctly:

if [ "pass_tc11" != "" ]; then
#     ^
#     missing $

Anyway, to check if a variable is empty or not you can use -z --> the string is empty:

if [ ! -z "$pass_tc11" ]; then
   echo "hi, I am not empty"
fi

or -n --> the length is non-zero:

if [ -n "$pass_tc11" ]; then
   echo "hi, I am not empty"
fi

From man test:

-z STRING

the length of STRING is zero

-n STRING

the length of STRING is nonzero

Samples:

$ [ ! -z "$var" ] && echo "yes"
$

$ var=""
$ [ ! -z "$var" ] && echo "yes"
$

$ var="a"
$ [ ! -z "$var" ] && echo "yes"
yes

$ var="a"
$ [ -n "$var" ] && echo "yes"
yes

def function(a):
    if a == '1':
        print ('1a')
    elif a == '2':
        print ('2a')
    else:
        print ('3a')

If you're using a WebView you'll have to intercept the clicks yourself if you don't want the default Android behaviour.

You can monitor events in a WebView using a WebViewClient. The method you want is shouldOverrideUrlLoading(). This allows you to perform your own action when a particular URL is selected.

You set the WebViewClient of your WebView using the setWebViewClient() method.

If you look at the WebView sample in the SDK there's an example which does just what you want. It's as simple as:

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}

rem out the @ECHO OFF and call your batch file redirectin ALL output to a log file..

c:> yourbatch.bat (optional parameters) > yourlogfile.txt 2>&1

found at http://www.robvanderwoude.com/battech_debugging.php

IT WORKS!! don't forget the 2>&1...

WIZ

There is actually a Synchronous function for this:

http://nodejs.org/api/fs.html#fs_fs_readfilesync_filename_encoding

Asynchronous

fs.readFile(filename, [encoding], [callback])

Asynchronously reads the entire contents of a file. Example:

fs.readFile('/etc/passwd', function (err, data) {
  if (err) throw err;
  console.log(data);
});

The callback is passed two arguments (err, data), where data is the contents of the file.

If no encoding is specified, then the raw buffer is returned.

SYNCHRONOUS

fs.readFileSync(filename, [encoding])

Synchronous version of fs.readFile. Returns the contents of the file named filename.

If encoding is specified then this function returns a string. Otherwise it returns a buffer.

var text = fs.readFileSync('test.md','utf8')
console.log (text)

For anyone else arriving here from Google search on how to do a string replacement on all columns (for example, if one has multiple columns like the OP's 'range' column): Pandas has a built in replace method available on a dataframe object.

df.replace(',', '-', regex=True)

Source: Docs

In my case this worked for python 2.7:

data = read_csv(filename, encoding = "ISO-8859-1", dtype={'name_of_colum': unicode}, low_memory=False) 

And for python 3, only:

data = read_csv(filename, encoding = "ISO-8859-1", low_memory=False) 

Check this.

This is a port of Mozilla Universal Charset Detector and you can use it like this...

With the React Devtools installed you can run this from the browser console:

__REACT_DEVTOOLS_GLOBAL_HOOK__.renderers.forEach(r => console.log(`${r.rendererPackageName}: ${r.version}`))

Which outputs something like:

react-dom: 16.12.0

Just for the record, in C++, if you can use either (i.e.) you don't care about the ordering of operations (you just want to increment or decrement and use it later) the prefix operator is more efficient since it doesn't have to create a temporary copy of the object. Unfortunately, most people use posfix (var++) instead of prefix (++var), just because that is what we learned initially. (I was asked about this in an interview). Not sure if this is true in C#, but I assume it would be.

Something like this will work

arr = ["A", "B", "C", "B", "A"]
arr.inject(Hash.new(0)) { |h,e| h[e] += 1; h }.
    select { |k,v| v > 1 }.
    collect { |x| x.first }

That is, put all values to a hash where key is the element of array and value is number of occurences. Then select all elements which occur more than once. Easy.

Just Add a primary key to the table. That's it. Problem solved.

ALTER TABLE <TABLE_NAME>
ADD CONSTRAINT <CONSTRAINT_NAME> PRIMARY KEY(<COLUMN_NAME>)

try

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({  

 url: 'api.php',                        
 data: 'id1='+q+'',                                                         
 dataType: 'json',
 success: function(data)          
  {

    id = data[0];              
   vname = data[1];
   printWithAjax();
}
      });



}//end of the for statement

I tried out the accepted answer but I still had a problem with the content alignment. Adding a ":before" selector as shown below fixed the issue:

// LESS HELPER
.clearfix()
{
    &:after, &:before{
       content: " "; /* Older browser do not support empty content */
       visibility: hidden;
       display: block;
       height: 0;
       clear: both;
    }
}

LESS above will compile to CSS below:

clearfix:after,
clearfix:before {
  content: " ";
  /* Older browser do not support empty content */
  visibility: hidden;
  display: block;
  height: 0;
  clear: both;
}

OK. We have official document now. It talked all I have mentioned, in a better way.

Read more detailed here.

Yes, the main difference is surfaceView can be updated on the background thread. However, there are more you might care.

• surfaceView has dedicate surface buffer while all the view shares one surface buffer that is allocated by ViewRoot. In another word, surfaceView cost more resources.

• surfaceView cannot be hardware accelerated (as of JB4.2) while 95% operations on normal View are HW accelerated using openGL ES.

• More work should be done to create your customized surfaceView. You need to listener to the surfaceCreated/Destroy Event, create an render thread, more importantly, synchronized the render thread and main thread. However, to customize the View, all you need to do is override onDraw method.

• The timing to update is different. Normal view update mechanism is constraint or controlled by the framework:You call view.invalidate in the UI thread or view.postInvalid in other thread to indicate to the framework that the view should be updated. However, the view won't be updated immediately but wait until next VSYNC event arrived. The easy approach to understand VSYNC is to consider it is as a timer that fire up every 16ms for a 60fps screen. In Android, all the normal view update (and display actually but I won't talk it today), is synchronized with VSYNC to achieve better smoothness. Now,back to the surfaceView, you can render it anytime as you wish. However, I can hardly tell if it is an advantage, since the display is also synchronized with VSYNC, as stated previously.

calls/sets object variables. Ex:

$obj = new StdClass;
$obj->foo = 'bar';
var_dump($obj);

=> Sets key/value pairs for arrays. Ex:

$array = array(

);
var_dump($array);

Visibility : Hidden Vs Collapsed

Consider following code which only shows three Labels and has second Label visibility as Collapsed:

 <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">
    <StackPanel.Resources>
        <Style TargetType="Label">
            <Setter Property="Height" Value="30" />
            <Setter Property="Margin" Value="0"/>
            <Setter Property="BorderBrush" Value="Black"/>
            <Setter Property="BorderThickness" Value="1" />
        </Style>
    </StackPanel.Resources>
    <Label Width="50" Content="First"/>
    <Label Width="50" Content="Second" Visibility="Collapsed"/>
    <Label Width="50" Content="Third"/>
</StackPanel>

Output Collapsed:

Now change the second Label visibility to Hiddden.

<Label Width="50" Content="Second" Visibility="Hidden"/>

Output Hidden:

As simple as that.

In oracle, generally speaking, there are number of facts that I will mention in following section:

• Each database can have many Schema/User (Logical division).
• Each database can have many tablespaces (Logical division).
• A schema is the set of objects (tables, indexes, views, etc) that belong to a user.
• In Oracle, a user can be considered the same as a schema.
• A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group all of an application’s objects to simplify some administrative operations. You may have a tablespace for application data and an additional one for application indexes.

Therefore, your question, "to see all tablespaces and datafiles belong to SCOTT" is s bit wrong.

However, there are some DBA views encompass information about all database objects, regardless of the owner. Only users with DBA privileges can access these views: DBA_DATA_FILES, DBA_TABLESPACES, DBA_FREE_SPACE, DBA_SEGMENTS.

So, connect to your DB as sysdba and run query through these helpful views. For example this query can help you to find all tablespaces and their data files that objects of your user are located:

SELECT DISTINCT sgm.TABLESPACE_NAME , dtf.FILE_NAME
FROM DBA_SEGMENTS sgm
JOIN DBA_DATA_FILES dtf ON (sgm.TABLESPACE_NAME = dtf.TABLESPACE_NAME)
WHERE sgm.OWNER = 'SCOTT'

}

Not sure if there's a drawback, but this seems quite concise:

arr.slice(-1)[0] 

or

arr.slice(-1).pop()

Both will return undefined if the array is empty.

If you need deep support, you can use an old school technique:

textarea {
    max-width: /* desired fixed width */ px;
    min-width: /* desired fixed width */ px;
    min-height: /* desired fixed height */ px;
    max-height: /* desired fixed height */ px;
}

Rename it to .zip, then extract it.

In cases where I don't care whether the variable is undef or equal to '', I usually summarize it as:

$name = "" unless defined $name;
if($name ne '') {
  # do something with $name
}

There's two area sizes to consider, the window and the html. If the html width, for example, is greater than window width then a scroll bar may be present on the user interface. So it's a matter of reading the window proportions and the html proportions and doing the basic math.

As for displaying an arrow overlaid atop the page, that's done with a simple classlist toggle, e.g. .hidden{display:none}

Here's a crossbrowser method for getting these proportions. (credit W3 Schools)

|| document.body.clientWidth;

var h = window.innerHeight || document.documentElement.clientHeight ||
document.body.clientHeight; ```

The questioner actually asked about int16 (etc) rather than (ugly) int16_t (etc).

There are no standard headers - nor any in Linux's /usr/include/ folder that define them without the "_t".

$provide service

They are technically the same thing, it's actually a different notation of using the provider function of the $provide service.

• If you're using a class: you could use the service notation.
• If you're using an object: you could use the factory notation.

The only difference between the service and the factory notation is that the service is new-ed and the factory is not. But for everything else they both look, smell and behave the same. Again, it's just a shorthand for the $provide.provider function.

// Factory

angular.module('myApp').factory('myFactory', function() {

  var _myPrivateValue = 123;

  return {
    privateValue: function() { return _myPrivateValue; }
  };

});

// Service

function MyService() {
  this._myPrivateValue = 123;
}

MyService.prototype.privateValue = function() {
  return this._myPrivateValue;
};

angular.module('myApp').service('MyService', MyService);

Here is a method you can use:

    public static void RemoveAllByValue<K, V>(this Dictionary<K, V> dictionary, V value)
    {
        foreach (var key in dictionary.Where(
                kvp => EqualityComparer<V>.Default.Equals(kvp.Value, value)).
                Select(x => x.Key).ToArray())
            dictionary.Remove(key);
    }

Here are two examples of how to generate graphs in separate windows (frames), and, an example of how to generate graphs and save them into separate graphics files.

Okay, first the on-screen example. Notice that we use a separate instance of plt.figure(), for each graph, with plt.plot(). At the end, we have to call plt.show() to put it all on the screen.

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )

plt.show()

Another way to do this, is to use plt.show(block=False) inside the loop:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )
    plt.show( block=False )

Now, let's generate the graphs and instead, write them each to a file. Here we replace plt.show(), with plt.savefig( filename ). The difference from the previous example is that we don't have to account for ''blocking'' at each graph. Note also, that we number the file names. Here we use %03d so that we can conveniently have them in number order afterwards.

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )
    plt.savefig('myfilename%03d.png'%(n))

below solution worked for me in case of required number is float. Solution:

table=sorted(table,key=lambda x: float(x[5]))
for row in table[:]:
    Ntable.add_row(row)

I think You ask for Boolean algebra which describes the output of various operations performed on boolean variables. Just look at the article on Wikipedia.

The default dbpath for mongodb is /data/db.

There is no default config file, so you will either need to specify this when starting mongod with:

 mongod --config /etc/mongodb.conf

.. or use a packaged install of MongoDB (such as for Redhat or Debian/Ubuntu) which will include a config file path in the service definition.

Note: to check the dbpath and command-line options for a running mongod, connect via the mongo shell and run:

db.serverCmdLineOpts()

In particular, if a custom dbpath is set it will be the value of:

db.serverCmdLineOpts().parsed.dbpath           // MongoDB 2.4 and older
db.serverCmdLineOpts().parsed.storage.dbPath   // MongoDB 2.6+

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

when you use lxml all simple:

tree = lxml.html.fromstring(html)
i_need_element = tree.xpath('//a[@class="shared-components"]/@href')

but when use BeautifulSoup BS4 all simple too:

• first remove "//" and "@"
• second - add star before "="

try this magic:

soup = BeautifulSoup(html, "lxml")
i_need_element = soup.select ('a[class*="shared-components"]')

as you see, this does not support sub-tag, so i remove "/@href" part

I'm pretty sure the code is not using the System.Net.Http.HttpContent class, but instead Microsoft.Http.HttpContent. Microsoft.Http was the WCF REST Starter Kit, which never made it out preview before being placed in the .NET Framework. You can still find it here: http://aspnet.codeplex.com/releases/view/24644

I would not recommend basing new code on it.

NULL is not guaranteed to be 0 -- its exact value is architecture-dependent. Most major architectures define it to (void*)0.

'\0' will always equal 0, because that is how byte 0 is encoded in a character literal.

I don't remember whether C compilers are required to use ASCII -- if not, '0' might not always equal 48. Regardless, it's unlikely you'll ever encounter a system which uses an alternative character set like EBCDIC unless you're working on very obscure systems.

The sizes of the various types will differ on 64-bit systems, but the integer values will be the same.

Some commenters have expressed doubt that NULL be equal to 0, but not be zero. Here is an example program, along with expected output on such a system:

#include <stdio.h>

int main () {
    size_t ii;
    int *ptr = NULL;
    unsigned long *null_value = (unsigned long *)&ptr;
    if (NULL == 0) {
        printf ("NULL == 0\n"); }
    printf ("NULL = 0x");
    for (ii = 0; ii < sizeof (ptr); ii++) {
        printf ("%02X", null_value[ii]); }
    printf ("\n");
    return 0;
}

That program could print:

NULL == 0
NULL = 0x00000001

Not an official name per se, but I've heard vertical ellipsis referred to as "snowman" in SAS community.

I am also adding an answer that augments this a little bit because I came to this entry when searching for an answer, and this had almost what I needed, but I needed a bit more, which I got via @MrFlik 's answer and the R lazyeval vignettes.

I wanted to make a function that could take a dataframe and a vector of column names (as strings) that I want to be converted from a string to a Date object. I couldn't figure out how to make as.Date() take an argument that is a string and convert it to a column, so I did it as shown below.

Below is how I did this via SE mutate (mutate_()) and the .dots argument. Criticisms that make this better are welcome.

library(dplyr)

dat <- data.frame(a="leave alone",
                  dt="2015-08-03 00:00:00",
                  dt2="2015-01-20 00:00:00")

# This function takes a dataframe and list of column names
# that have strings that need to be
# converted to dates in the data frame
convertSelectDates <- function(df, dtnames=character(0)) {
    for (col in dtnames) {
        varval <- sprintf("as.Date(%s)", col)
        df <- df %>% mutate_(.dots= setNames(list(varval), col))
    }
    return(df)
}

dat <- convertSelectDates(dat, c("dt", "dt2"))
dat %>% str

Another reason why many prefer hyphens in CSS id and class names is functionality.

Using keyboard shortcuts like option + left/right (or ctrl+left/right on Windows) to traverse code word by word stops the cursor at each dash, allowing you to precisely traverse the id or class name using keyboard shortcuts. Underscores and camelCase do not get detected and the cursor will drift right over them as if it were all one single word.

Response with RxJS

Say Like something in Angular

size$: Observable<number> = fromEvent(window, 'resize').pipe(
            debounceTime(250),
            throttleTime(300),
            mergeMap(() => of(document.body.clientHeight)),
            distinctUntilChanged(),
            startWith(document.body.clientHeight),
          );

If manual subscription desired (Or Not Angular)

this.size$.subscribe((g) => {
      console.log('clientHeight', g);
    })

Since my intial startWith Value might be incorrect (dispatch for correction)

window.dispatchEvent(new Event('resize'));

In say Angular (I could..)

<div class="iframe-container"  [style.height.px]="size$ | async" >..

Use GMT time zone to get an instance of the Calendar, set the time using the set method of Calendar class. The GMT timezone has 0 offset (not really important) and daylight saving time flag set to false.

    final Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));

    cal.set(Calendar.YEAR, 2011);
    cal.set(Calendar.MONTH, 9);
    cal.set(Calendar.DAY_OF_MONTH, 29);
    cal.set(Calendar.HOUR, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);

    cal.set(Calendar.YEAR, 2011);
    cal.set(Calendar.MONTH, 12);
    cal.set(Calendar.DAY_OF_MONTH, 21);
    cal.set(Calendar.HOUR, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    final Date endDate = cal.getTime();

    System.out.println((endDate.getTime() - startDate.getTime()) % (1000l * 60l * 60l * 24l));

By Timestamp, I presume you mean java.sql.Timestamp. You will notice that this class has a constructor that accepts a long argument. You can parse this using the DateFormat class:

DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("23/09/2007");
long time = date.getTime();
new Timestamp(time);

this is commonly known as nesting iterators into other iterators I think

What did the trick for me was to do cd src from my project directoy, and then use the php artisan command, since my artisan file was in the src folder. Here is my project structure:

project
|__ config
|__ src
    |__ app
    |__ ..
    |__ artisan  // hello there!
    |__ ...
|__ ...

I had similar problem and in my opinion best option is to use just a little bit of javascript or jquery.

You can get wanted divs to be same height by getting highest div value and applying that value to all other divs. If you have many divs and many solutions i suggest to write little advance js code to find out which of all divs is the highest and then use it's value.

With jquery and 2 divs it's very simple, here is example code:

$('.smaller-div').css('height',$('.higher-div').css('height'));

And for the end, there is 1 last thing. Their padding (top and bottom) must be the same ! If one have larger padding you need to eliminate padding difference.

I did this.

<div>
    <mat-select [(ngModel)]="selected">
        <mat-option *ngFor="let option of options" 
            [value]="option.id === selected.id ? selected : option">
            {{ option.name }}
        </mat-option>
    </mat-select>
</div>

Normally you can do [value]="option", unless you get your options from some database?? I think either the delay of getting the data causes it not to work, or the objects gotten are different in some way even though they are the same?? Weirdly enough it's most likely the later one, as I also tried [value]="option === selected ? selected : option" and it didn't work.

Use this.finishAffinity(); on that button instead of finish(); If it does not work then you can also try by adding android:noHistory="true" in your manifest and then finish your activity by uisng finish(); or finishAffinity();

Hope it helps....:)

It says that the file C:\wamp\www\mysite\php\includes\dbconn.inc doesn't exist, so the error is, you're missing the file.

You can USE PyPDF2 package

#install pyDF2
pip install PyPDF2

# importing all the required modules
import PyPDF2

# creating an object 
file = open('example.pdf', 'rb')

# creating a pdf reader object
fileReader = PyPDF2.PdfFileReader(file)

# print the number of pages in pdf file
print(fileReader.numPages)

Follow this Documentation http://pythonhosted.org/PyPDF2/

You're close... but use: if (Value1.StartsWith("abc"))

Alt+? / ?

You can find here all shortcuts

https://code.visualstudio.com/docs/customization/keybindings

You can install directly from the repository (note the type="source"):

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")

Sounds like you probably want a simple method like this:

public String getValueOrDefault(String value, String defaultValue) {
    return isNotNullOrEmpty(value) ? value : defaultValue;
}

Then:

String result = getValueOrDefault(System.getProperty("XYZ"), "default");

At this point, you don't need temp... you've effectively used the method parameter as a way of initializing the temporary variable.

If you really want temp and you don't want an extra method, you can do it in one statement, but I really wouldn't:

public class Test {
    public static void main(String[] args) {
        String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
        System.out.println("result: " + result);
        System.out.println("temp: " + temp);
    }

    private static boolean isNotNullOrEmpty(String str) {
        return str != null && !str.isEmpty();
    }
}

Just to expand on the answer(s) above, in my case, I required sending a yes/no against a single ID serialized to my backend catch.

I set the checkbox elements to contain the ID of a particular database column, aka (default checked):

(Laravel Blade)

<div class="checkbox">
    <label>
        <input type="checkbox" value="{{ $heading->id }}" checked> {{ $heading->name }}
    </label>
</div>

When I did my submission, I grabbed the data with:

(jQuery)

let form = $('#formID input[type="checkbox"]').map(function() {
                return { id: this.value, value: this.checked ? 1 : 0 };
           }).get();

var data = JSON.stringify(form);
$.post( "/your/endpoint", data );

The integer math solution that Ian provided is nice, but suffers from an integer overflow bug. Assuming the variables are all int, the solution could be rewritten to use long math and avoid the bug:

int pageCount = (-1L + records + recordsPerPage) / recordsPerPage;

If records is a long, the bug remains. The modulus solution does not have the bug.

Using CSS only:

#blockContainer {
display: -webkit-box;
display: -moz-box;
display: box;

-webkit-box-orient: vertical;
-moz-box-orient: vertical;
box-orient: vertical;
}
#blockA {
-webkit-box-ordinal-group: 2;
-moz-box-ordinal-group: 2;
box-ordinal-group: 2;
}
#blockB {
-webkit-box-ordinal-group: 3;
-moz-box-ordinal-group: 3;
box-ordinal-group: 3;

}

<div id="blockContainer">
 <div id="blockA">Block A</div>
 <div id="blockB">Block B</div>
 <div id="blockC">Block C</div>
</div>

Move temporarily .gitignore to .gitignore.bck

I know this is an old thread but I just wanted to add a little as the marked solution didn't solve the problem for me (although I tried many times).

The only way I could actually stop git form tracking the folder was to do the following:

1. Make a backup of the local folder and put in a safe place.
2. Delete the folder from your local repo
3. Make sure cache is cleared git rm -r --cached your_folder/
4. Add your_folder/ to .gitignore
5. Commit changes
6. Add the backup back into your repo

You should now see that the folder is no longer tracked.

Don't ask me why just clearing the cache didn't work for me, I am not a Git super wizard but this is how I solved the issue.

There is a simple work around. The alert only comes up when you have a large amount of data in your clipboard. Just copy a random cell before you close the workbook and it won't show up anymore!

terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:

import io

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage


def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos = set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
                                  password=password,
                                  caching=caching,
                                  check_extractable=True):
        interpreter.process_page(page)



    fp.close()
    device.close()
    text = retstr.getvalue()
    retstr.close()
    return text

I'm a PHP developer and to be able to work on my development environment with a certificate, I was able to do the same by finding the real SSL HTTPS/HTTP Certificate and deleting it.

The steps are :

1. In the address bar, type "chrome://net-internals/#hsts".
2. Type the domain name in the text field below "Delete domain".
3. Click the "Delete" button.
4. Type the domain name in the text field below "Query domain".
5. Click the "Query" button.
6. Your response should be "Not found".

You can find more information at : http://classically.me/blogs/how-clear-hsts-settings-major-browsers

Although this solution is not the best, Chrome currently does not have any good solution for the moment. I have escalated this situation with their support team to help improve user experience.

Edit : you have to repeat the steps every time you will go on the production site.

Possible repeated question from How to overcome the CORS issue in ReactJS

CORS works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. This must be configured in the server to allow cross domain.

You can temporary solve this issue by a chrome plugin called CORS.

You can also use Json.NET.

return JsonConvert.SerializeObject(jsonResult.Data);

I had run into the same issue while I was dealing with large dataset. One thing I've noticed was the NoSuchElementException is thrown when the Scanner reaches the endOfFile, where it is not going to affect our data.

Here, I've placed my code in try block and catch block handles the exception. You can also leave it empty, if you don't want to perform any task.

For the above question, because you are using file.next() both in the condition and in the while loop you can handle the exception as

while(!file.next().equals(treasure)){
    try{
        file.next(); //stack trace error here
       }catch(NoSuchElementException e) {  }
}

This worked perfectly for me, if there are any corner cases for my approach, do let me know through comments.

If copying to/from your desktop machine, use WinSCP, or if on Linux, Nautilus supports SCP via the Connect To Server option.

scp can only copy files to a machine running sshd, hence you need to run the client software on the remote machine from the one you are running scp on.

If copying on the command line, use:

# copy from local machine to remote machine
scp localfile user@host:/path/to/whereyouwant/thefile

or

# copy from remote machine to local machine
scp user@host:/path/to/remotefile localfile

Not sure if anyone post this. Found this solution simple to use!. The SoftKeyboard class is on gist.github.com. But while keyboard popup/hide event callback we need a handler to properly do things on UI:

/*
Somewhere else in your code
*/
RelativeLayout mainLayout = findViewById(R.layout.main_layout); // You must use your root layout
InputMethodManager im = (InputMethodManager) getSystemService(Service.INPUT_METHOD_SERVICE);

/*
Instantiate and pass a callback
*/
SoftKeyboard softKeyboard;
softKeyboard = new SoftKeyboard(mainLayout, im);
softKeyboard.setSoftKeyboardCallback(new SoftKeyboard.SoftKeyboardChanged()
{

    @Override
    public void onSoftKeyboardHide() 
    {
        // Code here
        new Handler(Looper.getMainLooper()).post(new Runnable() {
                @Override
                public void run() {
                    // Code here will run in UI thread
                    ...
                }
            });
    }

    @Override
    public void onSoftKeyboardShow() 
    {
        // Code here
        new Handler(Looper.getMainLooper()).post(new Runnable() {
                @Override
                public void run() {
                    // Code here will run in UI thread
                    ...
                }
            });

    }   
});

forEach: If you want to perform an action on the elements of an Array and it is same as you use for loop. The result of this method does not give us an output buy just loop through the elements.

map: If you want to perform an action on the elements of an array and also you want to store the output of your action into an Array. This is similar to for loop within a function that returns the result after each iteration.

Hope this helps.

To get the last element of an array, use:

$lastElement = array_slice($array, -1)[0];

Benchmark

I iterated 1,000 times, grabbing the last element of small and large arrays that contained 100 and 50,000 elements, respectively.

Method: $array[count($array)-1];
Small array (s): 0.000319957733154
Large array (s): 0.000526905059814
Note: Fastest!  count() must access an internal length property.
Note: This method only works if the array is naturally-keyed (0, 1, 2, ...).

Method: array_slice($array, -1)[0];
Small array (s): 0.00145292282104
Large array (s): 0.499367952347

Method: array_pop((array_slice($array, -1, 1)));
Small array (s): 0.00162816047668
Large array (s): 0.513121843338

Method: end($array);
Small array (s): 0.0028350353241
Large array (s): 4.81077480316
Note: Slowest...

I used PHP Version 5.5.32.

You might also find it useful to know generally what these data types are used for:

• :string - is for small data types such as a title. (Should you choose string or text?)
• :text - is for longer pieces of textual data, such as a paragraph of information
• :binary - is for storing data such as images, audio, or movies.
• :boolean - is for storing true or false values.
• :date - store only the date
• :datetime - store the date and time into a column.
• :time - is for time only
• :timestamp - for storing date and time into a column.(What's the difference between datetime and timestamp?)
• :decimal - is for decimals (example of how to use decimals).
• :float - is for decimals. (What's the difference between decimal and float?)
• :integer - is for whole numbers.
• :primary_key - unique key that can uniquely identify each row in a table

There's also references used to create associations. But, I'm not sure this is an actual data type.

New Rails 4 datatypes available in PostgreSQL:

• :hstore - storing key/value pairs within a single value (learn more about this new data type)
• :array - an arrangement of numbers or strings in a particular row (learn more about it and see examples)
• :cidr_address - used for IPv4 or IPv6 host addresses
• :inet_address - used for IPv4 or IPv6 host addresses, same as cidr_address but it also accepts values with nonzero bits to the right of the netmask
• :mac_address - used for MAC host addresses

Learn more about the address datatypes here and here.

Also, here's the official guide on migrations: http://edgeguides.rubyonrails.org/migrations.html

If you want the month year unique pair, using apply is pretty sleek.

df['mnth_yr'] = df['date_column'].apply(lambda x: x.strftime('%B-%Y')) 

Outputs month-year in one column.

Don't forget to first change the format to date-time before, I generally forget.

df['date_column'] = pd.to_datetime(df['date_column'])

DECLARE @id INT 
SET @id = 0 
UPDATE cartemp
SET @id = CarmasterID = @id + 1 
GO

<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>


$id = implode(',',$_POST['id']);
echo $id

you cannot echo an array because it will just print out Array. If you wanna print out an array use print_r.

print_r($_POST['id']);

There is a new official design library, just add this to your build.gradle: for details visit android developers page

compile 'com.android.support:design:27.0.0'

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.

In case of entity framework FK in dependent must also be its PK so in your case you should use:

public class Boo
{
    [Key, ForeignKey("Foo")]
    public string BooId{get;set;}
    public Foo Foo{get;set;}
}

Or fluent mapping

modelBuilder.Entity<Foo>()
            .HasOptional(f => f.Boo)
            .WithRequired(s => s.Foo);

The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options value as a default.

As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.

Mathematica or Maple will allow you to give as many decimal places as your heart desires.

EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.

On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin (usually 2e-308).

Compare these two analyses.

x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1)  #Should throw an error

x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2)  #ok

In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.

As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr package.

mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")

These are slower and more memory intensive to use than regular (double precision) numeric vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.

Use Path.GetFileNameWithoutExtension. Path is in System.IO namespace.

var express = require('express');    
var app = express();
    app.set('port', Config.port || 8881);
    var server = app.listen(app.get('port'), function() {
        console.log('Express server listening on port ' + server.address().port); 
    });

This is how simply I sort from previous examples:

if my array is items:

0: {id: 14, auctionID: 76, userID: 1, amount: 39}
1: {id: 1086, auctionID: 76, userID: 1, amount: 55}
2: {id: 1087, auctionID: 76, userID: 1, amount: 55}

I thought simply calling items.sort() would sort it it, but there was two problems: 1. Was sorting them strings 2. Was sorting them first key

This is how I modified the sort function:

for(amount in items){
if(item.hasOwnProperty(amount)){

i.sort((a, b) => a.amount - b.amount);
}
}

This is the snippet to store environment variable and access it.

node {
   withEnv(["ENABLE_TESTS=true", "DISABLE_SQL=false"]) {
      stage('Select Jenkinsfile') {
          echo "Enable test?: ${env.DEVOPS_SKIP_TESTS}
          customStep script: this
      }
   }
}

Note: The value of environment variable is coming as a String. If you want to use it as a boolean then you have to parse it using Boolean.parse(env.DISABLE_SQL).

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

This is even more frustrating because now (.net 5) MS have marked many (all) of their methods that take a string instead of a Uri as obsolete.

Anyway, probably a better way to manipulate relative Uris is to give it what it wants:

var requestUri = new Uri("x://x").MakeRelativeUri(
   new UriBuilder("x://x") { Path = path, Query = query }.Uri);

You can use the other answers to actually build the query string.

Assuming the first answer is referring to the C-like syntax (char *)(0x135700 +0xec1a04f) then the answer to do rwatch *0x135700+0xec1a04f is incorrect. The correct syntax is rwatch *(0x135700+0xec1a04f).

The lack of ()s there caused me a great deal of pain trying to use watchpoints myself.

I had same trouble and did as mentioned above.

• Put the plist in dropbox.
• Over the download file button, below an image of the document with mouse right button select the copy link action. This link is already something like https://dl.dropboxusercontent.com/s/xyz123/app.plist?stuff=stuff with many params.
• Remove the parameters (kept only address between https and .plist)
• Browse for url encode online, selected one of those links, copy, paste, execute, then the resulting text copied and pasted into the html where I have the itms-services link. By the way I have this html in two different locations, one of those is where the ipa is located.
• Make sure the plist includes absolute references to the ipa file.

Both pages worked successfully for installing the app in iphones with ios 7.1

But, now iphones with ios 7.0x can't install the app.

I created a new question: upgraded adhoc app deployment doesnt work on ios previous to 7.1

Both issues are tightly related, and also bonded by the lack of official references.

I created my own functions which work really nicely:

def writeDict(dict, filename, sep):
    with open(filename, "a") as f:
        for i in dict.keys():            
            f.write(i + " " + sep.join([str(x) for x in dict[i]]) + "\n")

It will store the keyname first, followed by all values. Note that in this case my dict contains integers so that's why it converts to int. This is most likely the part you need to change for your situation.

def readDict(filename, sep):
    with open(filename, "r") as f:
        dict = {}
        for line in f:
            values = line.split(sep)
            dict[values[0]] = {int(x) for x in values[1:len(values)]}
        return(dict)

foreach($shipmentarr as $index=>$val){    
    $additionalService = array();

    foreach($additionalService[$index] as $key => $value) {

        array_push($additionalService,$value);

    }
}

I believe this error message is due to a "zombie transaction".

Look for possible areas where the transacton is being committed twice (or rolled back twice, or rolled back and committed, etc.). Does the .Net code commit the transaction after the SP has already committed it? Does the .Net code roll it back on encountering an error, then attempt to roll it back again in a catch (or finally) clause?

It's possible an error condition was never being hit on the old server, and thus the faulty "double rollback" code was never hit. Maybe now you have a situation where there is some configuration error on the new server, and now the faulty code is getting hit via exception handling.

Can you debug into the error code? Do you have a stack trace?

Also, to use your new namespaced class you can also do

var jenine:com.newnamespace.subspace.Jenine = com.newnamespace.subspace.Jenine()

Just the same way as you would do in normal Java code.

for (Map.Entry<String, String> entry : countries.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    // ...
}

However, scriptlets (raw Java code in JSP files, those <% %> things) are considered a poor practice. I recommend to install JSTL (just drop the JAR file in /WEB-INF/lib and declare the needed taglibs in top of JSP). It has a <c:forEach> tag which can iterate over among others Maps. Every iteration will give you a Map.Entry back which in turn has getKey() and getValue() methods.

Here's a basic example:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach items="${map}" var="entry">
    Key = ${entry.key}, value = ${entry.value}<br>
</c:forEach>

Thus your particular issue can be solved as follows:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<select name="country">
    <c:forEach items="${countries}" var="country">
        <option value="${country.key}">${country.value}</option>
    </c:forEach>
</select>

You need a Servlet or a ServletContextListener to place the ${countries} in the desired scope. If this list is supposed to be request-based, then use the Servlet's doGet():

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    Map<String, String> countries = MainUtils.getCountries();
    request.setAttribute("countries", countries);
    request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);
}

Or if this list is supposed to be an application-wide constant, then use ServletContextListener's contextInitialized() so that it will be loaded only once and kept in memory:

public void contextInitialized(ServletContextEvent event) {
    Map<String, String> countries = MainUtils.getCountries();
    event.getServletContext().setAttribute("countries", countries);
}

In both cases the countries will be available in EL by ${countries}.

Hope this helps.

As the message error says, you need to Increase the length of your column to fit the length of the data you are trying to insert (0000-00-00)

EDIT 1:

Following your comment, I run a test table:

mysql> create table testDate(id int(2) not null auto_increment, pdd date default null, primary key(id));
Query OK, 0 rows affected (0.20 sec)

Insertion:

mysql> insert into testDate values(1,'0000-00-00');
Query OK, 1 row affected (0.06 sec)

EDIT 2:

So, aparently you want to insert a NULL value to pdd field as your comment states ? You can do that in 2 ways like this:

Method 1:

mysql> insert into testDate values(2,'');
Query OK, 1 row affected, 1 warning (0.06 sec)

Method 2:

mysql> insert into testDate values(3,NULL);
Query OK, 1 row affected (0.07 sec)

EDIT 3:

You failed to change the default value of pdd field. Here is the syntax how to do it (in my case, I set it to NULL in the start, now I will change it to NOT NULL)

mysql> alter table testDate modify pdd date not null;
Query OK, 3 rows affected, 1 warning (0.60 sec)
Records: 3  Duplicates: 0  Warnings: 1

I faced a similar kind of issue where my task was to push a message to SQS within a particular timeout. I used the trivial logic of executing it via another thread and waiting on its future object by specifying the timeout. This would give me a TIMEOUT exception in case of timeouts.

final Future<ISendMessageResult> future = 
timeoutHelperThreadPool.getExecutor().submit(() -> {
  return getQueueStore().sendMessage(request).get();
});
try {
  sendMessageResult = future.get(200, TimeUnit.MILLISECONDS);
  logger.info("SQS_PUSH_SUCCESSFUL");
  return true;

} catch (final TimeoutException e) {
  logger.error("SQS_PUSH_TIMEOUT_EXCEPTION");
}

But there are cases where you can't stop the code being executed by another thread and you get true negatives in that case.

For example - In my case, my request reached SQS and while the message was being pushed, my code logic encountered the specified timeout. Now in reality my message was pushed into the Queue but my main thread assumed it to be failed because of the TIMEOUT exception. This is a type of problem which can be avoided rather than being solved. Like in my case I avoided it by providing a timeout which would suffice in nearly all of the cases.

If the code you want to interrupt is within you application and is not something like an API call then you can simply use

future.cancel(true)

However do remember that java docs says that it does guarantee that the execution will be blocked.

"Attempts to cancel execution of this task. This attempt will fail if the task has already completed, has already been cancelled,or could not be cancelled for some other reason. If successful,and this task has not started when cancel is called,this task should never run. If the task has already started,then the mayInterruptIfRunning parameter determines whether the thread executing this task should be interrupted inan attempt to stop the task."

EDIT: This is bad advice. Use "o", as above. "s" does the wrong thing.

I always use this:

dateTime.ToUniversalTime().ToString("s");

This is correct if your schema looks like this:

<xs:element name="startdate" type="xs:dateTime"/>

Which would result in:

<startdate>2002-05-30T09:00:00</startdate>

You can get more information here: http://www.w3schools.com/xml/schema_dtypes_date.asp

I use following in one of my common header in the project that covers all bases:

#define _USE_MATH_DEFINES
#include <cmath>

#ifndef M_PI
#define M_PI (3.14159265358979323846)
#endif

#ifndef M_PIl
#define M_PIl (3.14159265358979323846264338327950288)
#endif

On a side note, all of below compilers define M_PI and M_PIl constants if you include <cmath>. There is no need to add `#define _USE_MATH_DEFINES which is only required for VC++.

x86 GCC 4.4+
ARM GCC 4.5+
x86 Clang 3.0+

You are looking for the jQuery extend method. This will allow you to add other members to your already created JS object.

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

You cannot put primitive types into collections. However, you can declare them using their corresponding object wrappers and still add the primitive values, as long as the boxing allows you.

I encountered this issue while importing some of the files from the Add Health data into R (see: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/21600?archive=ICPSR&q=21600 ) For example, the following command to read the DS12 data file in tab separated .tsv format will generate the following error:

ds12 <- read.table("21600-0012-Data.tsv", sep="\t", comment.char="", 
quote = "\"", header=TRUE)

Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, 
na.strings,  : line 2390 did not have 1851 elements

It appears there is a slight formatting issue with some of the files that causes R to reject the file. At least part of the issue appears to be the occasional use of double quotes instead of an apostrophe that causes an uneven number of double quote characters in a line.

After fiddling, I've identified three possible solutions:

1. Open the file in a text editor and search/replace all instances of a quote character " with nothing. In other words, delete all double quotes. For this tab-delimited data, this meant only that some verbatim excerpts of comments from subjects were no longer in quotes which was a non-issue for my data analysis.

2. With data stored on ICPSR (see link above) or other archives another solution is to download the data in a new format. A good option in this case is to download the Stata version of the DS12 and then open it using the read.dta command as follows:

   library(foreign)
   ds12 <- read.dta("21600-0012-Data.dta")
   

3. A related solution/hack is to open the .tsv file in Excel and re-save it as a tab separated text file. This seems to clean up whatever formatting issue makes R unhappy.

None of these are ideal in that they don't quite solve the problem in R with the original .tsv file but data wrangling often requires the use of multiple programs and formats.

The answer here is not clear, so I wanted to add more detail.

Using the link provided above, I performed the following step.

In my XML config manager I changed the "Provider" to SQLOLEDB.1 rather than SQLNCLI.1. This got me past this error.

This information is available at the link the OP posted in the Answer.

The link the got me there: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/fab0e3bf-4adf-4f17-b9f6-7b7f9db6523c/

The Literal meaning of instance is "an example or single occurrence of something." which is very closer to the Instance in Java terminology.

Java follows dynamic loading, which is not like C language where the all code is copied into the RAM at runtime. Lets capture this with an example.

   class A
    {
    int x=0;
    public static void main(String [] args)    
     {
    int y=0;
    y=y+1;
    x=x+1;
     }   

    }

Let us compile and run this code.

step 1: javac A.class (.class file is generated which is byte code)

step 2: java A (.class file is converted into executable code)

During the step 2,The main method and the static elements are loaded into the RAM for execution. In the above scenario, No issue until the line y=y+1. But whenever x=x+1 is executed, the run time error will be thrown as the JVM does not know what the x is which is declared outside the main method(non-static).

So If by some means the content of .class file is available in the memory for CPU to execute, there is no more issue.

This is done through creating the Object and the keyword NEW does this Job.

"The concept of reserving memory in the RAM for the contents of hard disk (here .class file) at runtime is called Instance "

The Object is also called the instance of the class.

For HTTP things, the current choice should be: Requests- HTTP for Humans

My simplest solution to this.

iframe {
    margin:auto;
    display:block;
}

On Linux, just run below command at terminal:

$ curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

After do this, close the current terminal and open it again. And then, run below command to check yarn current version:

$ yarn --version

Consider it as an array of arrays and this will work for sure.

int mat[][] = { {10, 20, 30, 40, 50, 60, 70, 80, 90},
                {15, 25, 35, 45},
                {27, 29, 37, 48},
                {32, 33, 39, 50, 51, 89},
              };


    for(int i=0; i<mat.length; i++) {
        for(int j=0; j<mat[i].length; j++) {
            System.out.println("Values at arr["+i+"]["+j+"] is "+mat[i][j]);
        }
    }

Another interesting solution to luch an exeternal application with a WinForm container is the follow:

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);


private void Form1_Load(object sender, EventArgs e)
{
    ProcessStartInfo psi = new ProcessStartInfo("notepad.exe");
    psi.WindowStyle = ProcessWindowStyle.Minimized;
    Process p = Process.Start(psi);
    Thread.Sleep(500);
    SetParent(p.MainWindowHandle, panel1.Handle);
    CenterToScreen();
    psi.WindowStyle = ProcessWindowStyle.Normal;
}

The step to ProcessWindowStyle.Minimized from ProcessWindowStyle.Normal remove the annoying delay.

Thanks to Larry's script, which worked perfectly well in IE10, this is what I've used:

$('#' + id)[0].innerHTML = result;
$('#' + id + " script").each(function() { this.text = this.text || $(this).text();} );

Two typical problems:

1. Missing the ProjectInstaller class (as @MiguelAngelo has pointed)
2. The command prompt must “Run as Administrator”

Use conditional comments in HTML, like this:

<!--[if IE 8]>
<style>...</style>
<![endif]-->

See here: http://www.quirksmode.org/css/condcom.html

You can test for IE versions reliably and also be sure other browsers won't be confused.

you can also skip creating dictionary altogether. i used below approach to same problem .

 mappedItems: {};
 items.forEach(item => {     
        if (mappedItems[item.key]) {
           mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount});
        } else {
          mappedItems[item.key] = [];
          mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount}));
        }
    });

Try this:

^[1-9]\d*$

Here is Demo

keyboard

• sudo pip install keyboard
• https://github.com/boppreh/keyboard

Take full control of your keyboard with this small Python library. Hook global events, register hotkeys, simulate key presses and much more.

Global event hook on all keyboards (captures keys regardless of focus). Listen and sends keyboard events. Works with Windows and Linux (requires sudo), with experimental OS X support (thanks @glitchassassin!). Pure Python, no C modules to be compiled. Zero dependencies. Trivial to install and deploy, just copy the files. Python 2 and 3. Complex hotkey support (e.g. Ctrl+Shift+M, Ctrl+Space) with controllable timeout. Includes high level API (e.g. record and play, add_abbreviation). Maps keys as they actually are in your layout, with full internationalization support (e.g. Ctrl+ç). Events automatically captured in separate thread, doesn't block main program. Tested and documented. Doesn't break accented dead keys (I'm looking at you, pyHook). Mouse support available via project mouse (pip install mouse).

From README.md:

import keyboard

keyboard.press_and_release('shift+s, space')

keyboard.write('The quick brown fox jumps over the lazy dog.')

# Press PAGE UP then PAGE DOWN to type "foobar".
keyboard.add_hotkey('page up, page down', lambda: keyboard.write('foobar'))

# Blocks until you press esc.
keyboard.wait('esc')

# Record events until 'esc' is pressed.
recorded = keyboard.record(until='esc')
# Then replay back at three times the speed.
keyboard.play(recorded, speed_factor=3)

# Type @@ then press space to replace with abbreviation.
keyboard.add_abbreviation('@@', '[email protected]')
# Block forever.
keyboard.wait()

Another way hasn't been given yet:

try:
    1/0
except Exception, e:
    print e.message

Output:

integer division or modulo by zero

args[0] might actually not be a message.

str(e) might return the string with surrounding quotes and possibly with the leading u if unicode:

'integer division or modulo by zero'

repr(e) gives the full exception representation which is not probably what you want:

"ZeroDivisionError('integer division or modulo by zero',)"

edit

My bad !!! It seems that BaseException.message has been deprecated from 2.6, finally, it definitely seems that there is still not a standardized way to display exception messages. So I guess the best is to do deal with e.args and str(e) depending on your needs (and possibly e.message if the lib you are using is relying on that mechanism).

For instance, with pygraphviz, e.message is the only way to display correctly the exception, using str(e) will surround the message with u''.

But with MySQLdb, the proper way to retrieve the message is e.args[1]: e.message is empty, and str(e) will display '(ERR_CODE, "ERR_MSG")'

Official Notice: success and error have been deprecated, please use the standard then method instead.

Deprecation Notice: The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. If $httpProvider.useLegacyPromiseExtensions is set to false then these methods will throw $http/legacy error.

File objects have a .readlines() method which will give you a list of the contents of the file, one line per list item. After that, you can just use normal list slicing techniques.

http://docs.python.org/library/stdtypes.html#file.readlines

If you use Python 3, you can use the python module img2pdf

install it using pip3 install img2pdf and then you can use it in a script using import img2pdf

sample code

import os
import img2pdf

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert([i for i in os.listdir('path/to/imageDir') if i.endswith(".jpg")]))

or (If you get any error with previous approach due to some path issue)

# convert all files matching a glob
import glob
with open("name.pdf","wb") as f:
    f.write(img2pdf.convert(glob.glob("/path/to/*.jpg")))

Only the OR part is tricky, but with a general boolean expression containing NOT OR AND the only nice solution is this:

REM if A == B OR C == C then yes

(call :strequ A B || call :strequ C C) && echo yes
exit /b

:strequ
if "%1" == "%2" exit /b 0
exit /b 1

With this matcher function you can get desirable behavior without component re-rendering. When url.length equals to 0, there's no optional parameters, with url.length equals to 1, there's 1 optional parameter. id - is the name of optional parameter.

  const routes: Routes = [
  {
    matcher: (segments) => {
      if (segments.length <= 1) {
        return {
          consumed: segments,
          posParams: {
            id: new UrlSegment(segments[0]?.path || '', {}),
          },
        };
      }
      return null;
    },
    pathMatch: 'prefix',
    component: UserComponent,
  }]

you can also make it overflow: auto and give a maximum fixed height and width that way, when the text or whatever is in there, overflows it'll show only the required scrollbar

I would suggest the following for Java8+.

/**
 * Creates a File if the file does not exist, or returns a
 * reference to the File if it already exists.
 */
private File createOrRetrieve(final String target) throws IOException{

    final Path path = Paths.get(target);

    if(Files.notExists(path)){
        LOG.info("Target file \"" + target + "\" will be created.");
        return Files.createFile(Files.createDirectories(path)).toFile();
    }
    LOG.info("Target file \"" + target + "\" will be retrieved.");
    return path.toFile();
}

/**
 * Deletes the target if it exists then creates a new empty file.
 */
private File createOrReplaceFileAndDirectories(final String target) throws IOException{

    final Path path = Paths.get(target);
    // Create only if it does not exist already
    Files.walk(path)
        .filter(p -> Files.exists(p))
        .sorted(Comparator.reverseOrder())
        .peek(p -> LOG.info("Deleted existing file or directory \"" + p + "\"."))
        .forEach(p -> {
            try{
                Files.createFile(Files.createDirectories(p));
            }
            catch(IOException e){
                throw new IllegalStateException(e);
            }
        });

    LOG.info("Target file \"" + target + "\" will be created.");

    return Files.createFile(
        Files.createDirectories(path)
    ).toFile();
}

Create an interface to define the 'indexer' interface

Then create your object with that index.

Note: this will still have same issues other answers have described with respect to enforcing the type of each item - but that's often exactly what you want.

You can make the generic type parameter whatever you need : ObjectIndexer< Dog | Cat>

// this should be global somewhere, or you may already be 
// using a library that provides such a type
export interface ObjectIndexer<T> {
  [id: string]: T;
}

interface ISomeObject extends ObjectIndexer<string>
{
    firstKey:   string;
    secondKey:  string;
    thirdKey:   string;
}

let someObject: ISomeObject = {
    firstKey:   'firstValue',
    secondKey:  'secondValue',
    thirdKey:   'thirdValue'
};

let key: string = 'secondKey';

let secondValue: string = someObject[key];

Typescript Playground

You can even use this in a generic constraint when defining a generic type:

export class SmartFormGroup<T extends IndexableObject<any>> extends FormGroup

Then T inside the class can be indexed :-)

This is a dynamic solution which works with all value types including objects :

class Session extends Map {
  set(id, value) {
    if (typeof value === 'object') value = JSON.stringify(value);
    sessionStorage.setItem(id, value);
  }

  get(id) {
    const value = sessionStorage.getItem(id);
    try {
      return JSON.parse(value);
    } catch (e) {
      return value;
    }
  }
}

Then :

const session = new Session();

session.set('name', {first: 'Ahmed', last : 'Toumi'});
session.get('name');

check your dependencies versions, you must have compatible versions put attention specially to com.google packages, must have same version like:

compile 'com.google.android.gms:play-services:8.3.0'
compile 'com.google.android.gms:play-services-maps:8.3.0'

Both are 8.3.0, if you have another version compilation will throw that exception.

Here's the complete answer for the future reader. Note that this is only possible in Laravel 5+.

First of all you'll need the doctrine/dbal package:

composer require doctrine/dbal

Now in your migration you can do this to make the column nullable:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

You may be wondering how to revert this operation. Sadly this syntax is not supported:

// Sadly does not work :'(
$table->integer('user_id')->unsigned()->change();

This is the correct syntax to revert the migration:

$table->integer('user_id')->unsigned()->nullable(false)->change();

Or, if you prefer, you can write a raw query:

public function down()
{
    /* Make user_id un-nullable */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
}

Hopefully you'll find this answer useful. :)

Here is a generic wrapper which can be used to convert a binary function to multi-parameters function. The benefit of this solution is that it is very generic and can be applied to any binary functions. You just need to do it once and then you can apply it any where.

To demo the idea, I use simple recursion to implement. It can be of course implemented with more elegant way that benefits from R's good support for functional paradigm.

fold_left <- function(f) {
return(function(...) {
    args <- list(...)
    return(function(...){
    iter <- function(result,rest) {
        if (length(rest) == 0) {
            return(result)
        } else {
            return(iter(f(result, rest[[1]], ...), rest[-1]))
        }
    }
    return(iter(args[[1]], args[-1]))
    })
})}

Then you can simply wrap any binary functions with it and call with positional parameters (usually data.frames) in the first parentheses and named parameters in the second parentheses (such as by = or suffix =). If no named parameters, leave second parentheses empty.

merge_all <- fold_left(merge)
merge_all(df1, df2, df3, df4, df5)(by.x = c("var1", "var2"), by.y = c("var1", "var2"))

left_join_all <- fold_left(left_join)
left_join_all(df1, df2, df3, df4, df5)(c("var1", "var2"))
left_join_all(df1, df2, df3, df4, df5)()

Open your cmd (command prompt) and run Python commmands from there. (on Windows go to run or search and type cmd) It should look like this:

python yourprogram.py 

This will execute your code in cmd and it will be left open. However to use python command, Python has to be properly installed so cmd recognizes it as a command. Checkout proper installation and variable registration for your OS if this does not happen

imagemagick@6 works for me!

brew unlink imagemagick
brew install imagemagick@6 && brew link imagemagick@6 --force

See this thread

You could put a _ViewStart.cshtml file inside the /Views/Public folder which would override the default one in the /Views folder and specify the desired layout:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

By analogy you could put another _ViewStart.cshtml file inside the /Views/Staff folder with:

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

You could also specify which layout should be used when returning a view inside a controller action but that's per action:

return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);

Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.

UPDATE:

As requested in the comments section here's an example of an action filter which would choose a master page:

public class LayoutInjecterAttribute : ActionFilterAttribute
{
    private readonly string _masterName;
    public LayoutInjecterAttribute(string masterName)
    {
        _masterName = masterName;
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        var result = filterContext.Result as ViewResult;
        if (result != null)
        {
            result.MasterName = _masterName;
        }
    }
}

and then decorate a controller or an action with this custom attribute specifying the layout you want:

[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
    return View();
}
