Programs & Examples On #Nptl

Generally if something works on various computers but fails on only one computer, then there's something wrong with that computer. Here are a few things to check:
(1) Are you running the same stuff on that computer -- OS including patches, etc.
(2) Does the computer report problems? Where to look depends on the OS, but it looks like you're using linux, so check syslog
(3) Run hardware diagnostics, e.g. the ones recommended here. Start with memory and disk checks in particular.

If you can't turn up any issues, then search for a similar issue in the bug parade for whichever VM you're using. Unfortunately if you're already on the latest version of the VM, then you won't necessarily find a fix.

Finally, one more option is simply to try another VM -- e.g. OpenJDK or JRockit, instead of Oracle's standard.

Those do both mean non-breaking space, yes.   is another synonym, in hex.

I do not know where you have used your methods that you put on your question but I could get the desired result if I use, on my ViewController class (in which I want to change the back button), on viewDidLoad() function, the following line:

self.navigationController?.navigationBar.backItem?.title = "Anything Else"

The result will be:

Before

After

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

Rebasing can be a real headache. You have to resolve the merge conflicts and continue rebasing. For example you can use the merge tool (which differs depending on your settings)

git mergetool

Then add your changes and go on

git rebase --continue

Good luck

do you want to write code for that or just use command-line feature 'command redirection' as follows:

app.exe >> output.txt

as demonstrated here: http://discomoose.org/2006/05/01/output-redirection-to-a-file-from-the-windows-command-line/ (Archived at archive.org)

EDIT: link dead, here's another example: http://pcsupport.about.com/od/commandlinereference/a/redirect-command-output-to-file.htm

env VAR=value myScript args ...

Canonical's releases use the user 'ubuntu' by default for anyone landing here with a ubuntu image that is coming up with the same problem.

@Jon: Jon, are you saying using multiple where clauses e.g.

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" 
            where r.Field<string>("UserName") != "YYYY"
            select r;

is more restictive than using

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" && r.Field<string>("UserName") != "YYYY"
            select r;

I think they are equivalent as far as the result goes.

However, I haven't tested, if using multiple where in the first example cause in 2 subqueries, i.e. .Where(r=>r.UserName!="XXXX").Where(r=>r.UserName!="YYYY) or the LINQ translator is smart enought to execute .Where(r=>r.UserName!="XXXX" && r.UsernName!="YYYY")

Just change it into

AlertDialog.Builder alert_Categoryitem = 
    new AlertDialog.Builder(YourActivity.this);

Instead of

AlertDialog.Builder alert_Categoryitem = 
    new AlertDialog.Builder(getApplicationContext());

$scope.$watch('age + name', function () {
  //called when name or age changed
});

@ts-expect-error

TS 3.9 introduces a new magic comment. @ts-expect-error will:

• have same functionality as @ts-ignore
• trigger an error, if actually no compiler error has been suppressed (= indicates useless flag)

if (false) {
  // @ts-expect-error: Let's ignore a single compiler error like this unreachable code 
  console.log("hello"); // compiles
}

// If @ts-expect-error didn't suppress anything at all, we now get a nice warning 
let flag = true;
// ...
if (flag) {
  // @ts-expect-error
  // ^~~~~~~~~~~~~~~^ error: "Unused '@ts-expect-error' directive.(2578)"
  console.log("hello"); 
}

Alternatives

@ts-ignore and @ts-expect-error can be used for all sorts of compiler errors. For type issues (like in OP), I recommend one of the following alternatives due to narrower error suppression scope:

? Use any type

// type assertion for single expression
delete ($ as any).summernote.options.keyMap.pc.TAB;

// new variable assignment for multiple usages
const $$: any = $
delete $$.summernote.options.keyMap.pc.TAB;
delete $$.summernote.options.keyMap.mac.TAB;

? Augment JQueryStatic interface

// ./global.d.ts
interface JQueryStatic {
  summernote: any;
}

// ./main.ts
delete $.summernote.options.keyMap.pc.TAB; // works

In other cases, shorthand module declarations or module augmentations for modules with no/extendable types are handy utilities. A viable strategy is also to keep not migrated code in .js and use --allowJs with checkJs: false.

You can use Spacers if all you want is a little bit of spacing between items in a row. The example below centers 2 Text widgets within a row with some spacing between them.

Spacer creates an adjustable, empty spacer that can be used to tune the spacing between widgets in a Flex container, like Row or Column.

In a row, if we want to put space between two widgets such that it occupies all remaining space.

    widget = Row (
    children: <Widget>[
      Spacer(flex: 20),
      Text(
        "Item #1",
      ),
      Spacer(),  // Defaults to flex: 1
      Text(
        "Item #2",
      ),
      Spacer(flex: 20),
    ]
  );

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

select @DateCreated, DATEDIFF(WEEK, @DateCreated, GETDATE())

Use a line algorithm to connect point A with point C, and in an outer loop, let point A wander towards point B with the same line algorithm and with the wandering coordinates, repeat drawing that line. You can probably also include a z delta with which is also incremented iteratively. For the line algorithm, just calculate two or three slopes for the delta change of each coordinate and set one slope to 1 after changing the two others proportionally so they are below 1. This is very important for drawing closed geometrical areas between connected mesh particles. Take a look at the Qt Elastic Nodes example and now imagine drawing triangles between the nodes after stretching this over a skeleton. As long as it will remain online

2019 Update (just for reference):

Starting with .NET Core 3.0, this feature is supported out of the box. To take advantage of the single-file executable publishing, just add the following line to the project configuration file:

<PropertyGroup>
  <PublishSingleFile>true</PublishSingleFile>
</PropertyGroup>

Now, dotnet publish should produce a single .exe file without using any external tool.

More documentation for this feature is available at https://github.com/dotnet/designs/blob/master/accepted/single-file/design.md.

Using java 8:

public static <T> List<T> removeDuplicates(List<T> list) {
    return list.stream().collect(Collectors.toSet()).stream().collect(Collectors.toList());
}

If you go to Windows, Preferences then select General, Editors, Text editors, you can set colors on that property page (and there's a link for setting MORE colors - General, Appearance, Colors and fonts).

That's with an Eclipse 3.3 build anyway.

add one ArrayList to second ArrayList as:

Arraylist1.addAll(Arraylist2);

EDIT : if you want to Create new ArrayList from two existing ArrayList then do as:

ArrayList<String> arraylist3=new ArrayList<String>();

arraylist3.addAll(Arraylist1); // add first arraylist

arraylist3.addAll(Arraylist2); // add Second arraylist

One way to do this is to pull your field into the rows section of the pivot table from the Filter section. Then group the values that you want to keep into a group, using the group option on the menu. After that is completed, drag your field back into the Filters section. The grouping will remain and you can check or uncheck one box to remove lots of values.

Well it's a very confusing kind of bug. There could be many reasons:

1. You are not mentioning the permissions in right place. Like right above application.
2. You are not using small letters.
3. In some case you also have to add Network state permission.
4. One which was my case there are some blank lines in manifest lines. Like there might be a blank line between permission tag and application line. Remove them and you are done. Hope it will help

tldr; both HTTP/1.1 and HTTP/2 headers are case-insensitive.

According to RFC 7230 (HTTP/1.1):

Each header field consists of a case-insensitive field name followed by a colon (":"), optional leading whitespace, the field value, and optional trailing whitespace.

https://tools.ietf.org/html/rfc7230#section-3.2

Also, RFC 7540 (HTTP/2):

Just as in HTTP/1.x, header field names are strings of ASCII
characters that are compared in a case-insensitive fashion.

https://tools.ietf.org/html/rfc7540#section-8.1.2

I got the same problem, the height of my menu bar provided by bootstrap was too big, actually i downloaded some wrong bootstrap, finally get rid of it by downloading the orignal bootstrap from this site.. http://getbootstrap.com/2.3.2/ want to use bootstrap in yii( netbeans) follow this tutorial, https://www.youtube.com/watch?v=XH_qG8gphaw... The voice is not present but the steps are slow you can easily understand and implement them. Thanks

I like...

@data = `cat /var/tmp/somefile`;

It's not as glamorous as others, but, it works all the same. And...

$todays_data = '/var/tmp/somefile' ;
open INFILE, "$todays_data" ; 
@data = <INFILE> ; 
close INFILE ;

Cheers.

It's best if you worked with DataSets and/or DataTables. Once you have that, ideally straight from your stored procedure with proper column names for headers, you can use the following method:

ws.Cells.LoadFromDataTable(<DATATABLE HERE>, true, OfficeOpenXml.Table.TableStyles.Light8);

.. which will produce a beautiful excelsheet with a nice table!

Now to serve your file, assuming you have an ExcelPackage object as in your code above called pck..

Response.Clear();

Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", "attachment;filename=" + sFilename);

Response.BinaryWrite(pck.GetAsByteArray());
Response.End();

how to club the 4 query's as a single query

show below query

1. total number of cases pending + 2.cases filed during this month ( base on sysdate) + total number of cases (1+2) + no. cases disposed where nse= disposed + no. of cases pending (other than nse <> disposed)

nsc = nature of case

report is taken on 06th of every month

( monthly report will be counted from 05th previous month to 05th present of present month)

You can use org.apache.commons.math.util.MathUtils from apache common

double round = MathUtils.round(double1, 2, BigDecimal.ROUND_HALF_DOWN);

You should probably set the property dt.Columns["columnName"].ReadOnly = false; before.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

I found this solution in this article

.parent-element {
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  transform-style: preserve-3d;
}

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

It work like a charm if the height of element is not fixed.

Got it working! I should have been building a JSONArray of JSONObjects and then add the array to a final "Addresses" JSONObject. Observe the following:

JSONObject json      = new JSONObject();
JSONArray  addresses = new JSONArray();
JSONObject address;
try
{
   int count = 15;

   for (int i=0 ; i<count ; i++)
   {
       address = new JSONObject();
       address.put("CustomerName"     , "Decepticons" + i);
       address.put("AccountId"        , "1999" + i);
       address.put("SiteId"           , "1888" + i);
       address.put("Number"            , "7" + i);
       address.put("Building"          , "StarScream Skyscraper" + i);
       address.put("Street"            , "Devestator Avenue" + i);
       address.put("City"              , "Megatron City" + i);
       address.put("ZipCode"          , "ZZ00 XX1" + i);
       address.put("Country"           , "CyberTron" + i);
       addresses.add(address);
   }
   json.put("Addresses", addresses);
}
catch (JSONException jse)
{ 

}
response.setContentType("application/json");
response.getWriter().write(json.toString());

This worked and returned valid and parse-able JSON. Hopefully this helps someone else in the future. Thanks for your help Marcel

Merge the changes from BranchA to BranchB. When you are on BranchB execute git merge BranchA

Form 2 is ok, and form 3 is also recommended.
Redundancy between name and id is caused by the need to keep compatibility, on html 5 some elements (as img, form, iframe and such) will lose their "name" attribute, and it's recommended to use just their id to reference them from now on :)

This is the correct way to make a pure call. No CSS.

<div style='background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABwAAAAFCAYAAABW1IzHAAAAHklEQVQokWNgGPaAkZHxPyMj439sYrSQo51PBgsAALa0ECF30JSdAAAAAElFTkSuQmCC)repeat-x center;'></div>

I had a similar problem, here's my solution:

1. Right click on your project and select Properties.
2. Select Java Build Path from the menu on the left.
3. Select the Order and Export tab.
4. From the list make sure the libraries or external jars you added to your project are checked.
5. Finally, clean your project & run.

Did you try a iFrame injection?

It injects the iFrame in the document and deletes itself (it is supposed to be then in the HTML DOM)

<iframe src="header.html" onload="this.before((this.contentDocument.body||this.contentDocument).children[0]);this.remove()"></iframe>

Expanding on @Sanbor's answer, the most efficient way to do this is to read the original file as a stream, and then also stream each chunk into a new file, and then lastly replace the original file with the new file.

async function findAndReplaceFile(regexFindPattern, replaceValue, originalFile) {
  const updatedFile = `${originalFile}.updated`;

  return new Promise((resolve, reject) => {
    const readStream = fs.createReadStream(originalFile, { encoding: 'utf8', autoClose: true });
    const writeStream = fs.createWriteStream(updatedFile, { encoding: 'utf8', autoClose: true });

    // For each chunk, do the find & replace, and write it to the new file stream
    readStream.on('data', (chunk) => {
      chunk = chunk.toString().replace(regexFindPattern, replaceValue);
      writeStream.write(chunk);
    });

    // Once we've finished reading the original file...
    readStream.on('end', () => {
      writeStream.end(); // emits 'finish' event, executes below statement
    });

    // Replace the original file with the updated file
    writeStream.on('finish', async () => {
      try {
        await _renameFile(originalFile, updatedFile);
        resolve();
      } catch (error) {
        reject(`Error: Error renaming ${originalFile} to ${updatedFile} => ${error.message}`);
      }
    });

    readStream.on('error', (error) => reject(`Error: Error reading ${originalFile} => ${error.message}`));
    writeStream.on('error', (error) => reject(`Error: Error writing to ${updatedFile} => ${error.message}`));
  });
}

async function _renameFile(oldPath, newPath) {
  return new Promise((resolve, reject) => {
    fs.rename(oldPath, newPath, (error) => {
      if (error) {
        reject(error);
      } else {
        resolve();
      }
    });
  });
}

// Testing it...
(async () => {
  try {
    await findAndReplaceFile(/"some regex"/g, "someReplaceValue", "someFilePath");
  } catch(error) {
    console.log(error);
  }
})()

If I've understood your question correctly, then you are looking for the mouseup event, rather than the click event:

$("#message_link").mouseup(function() {
    //Do stuff here
});

The mouseup event fires when the mouse button is released, and does not take into account whether the mouse button was pressed on that element, whereas click takes into account both mousedown and mouseup.

However, click should work fine, because it won't actually fire until the mouse button is released.

you can use inner join :

DELETE 
    ps 
FROM 
    posts ps INNER JOIN 
         (SELECT 
           distinct id 
         FROM 
             posts 
         GROUP BY id  
      HAVING COUNT(id) > 1 ) dubids on dubids.id = ps.id  

If you don't get any direct answer to this you could always run Fiddler on a windows machine and configure your browser on the Mac to use the windows machine as a proxy server. Not very satisfactory and requires a second machine (although it could be virtual).

Swift 2.0

Pass info using userInfo which is a optional Dictionary of type [NSObject : AnyObject]?

  let imageDataDict:[String: UIImage] = ["image": image]

  // Post a notification
  NSNotificationCenter.defaultCenter().postNotificationName(notificationName, object: nil, userInfo: imageDataDict)

 // Register to receive notification in your class
 NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: notificationName, object: nil)

 // handle notification
 func showSpinningWheel(notification: NSNotification) { 

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
 }

Swift 3.0 version and above

The userInfo now takes [AnyHashable:Any]? as an argument, which we provide as a dictionary literal in Swift

  let imageDataDict:[String: UIImage] = ["image": image]

  // post a notification
  NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
  // `default` is now a property, not a method call

 // Register to receive notification in your class
 NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

 // handle notification
 // For swift 4.0 and above put @objc attribute in front of function Definition  
 func showSpinningWheel(_ notification: NSNotification) {

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
 }

NOTE: Notification “names” are no longer strings, but are of type Notification.Name, hence why we are using NSNotification.Name(rawValue:"notificationName") and we can extend Notification.Name with our own custom notifications.

extension Notification.Name {
static let myNotification = Notification.Name("myNotification")
}

// and post notification like this
NotificationCenter.default.post(name: .myNotification, object: nil)

"Requery" is indeed what you what you want to run, but you could do that in Form A's "On Got Focus" event. If you have code in your Form_Load, perhaps you can move it to Form_Got_Focus.

Login with windows authentication mode and fist of all make sure that the sa authentication is enabled in the server, I am using SQL Server Management Studio, so I will show you how to do this there.

Right click on the server and click on Properties.

Now go to the Security section and select the option SQL Server and Windows Authentication mode

Once that is done, click OK. And then enable the sa login.

Go to your server, click on Security and then Logins, right click on sa and then click on Properties.

Now go tot Status and then select Enabled under Login. Then, click OK.

Now we can restart the SQLExpress, or the SQL you are using. Go to Services and Select the SQL Server and then click on Restart. Now open the SQL Server Management Studio and you should be able to login as sa user.

Every input has a form property which points to the form the input belongs to, so simply:

function doSomething(element) {
  var form = element.form;
}

I believe the normal answer is that it should be passed by value if you need to make a copy of it in your function. Pass it by const reference otherwise.

Here is a good discussion: http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/

As "Character Types" in the documentation points out, varchar(n), char(n), and text are all stored the same way. The only difference is extra cycles are needed to check the length, if one is given, and the extra space and time required if padding is needed for char(n).

However, when you only need to store a single character, there is a slight performance advantage to using the special type "char" (keep the double-quotes — they're part of the type name). You get faster access to the field, and there is no overhead to store the length.

I just made a table of 1,000,000 random "char" chosen from the lower-case alphabet. A query to get a frequency distribution (select count(*), field ... group by field) takes about 650 milliseconds, vs about 760 on the same data using a text field.

To fully understand this, you must grasp the following concepts:

Arrays are not pointers!

First of all (And it's been preached enough), arrays are not pointers. Instead, in most uses, they 'decay' to the address to their first element, which can be assigned to a pointer:

int a[] = {1, 2, 3};

int *p = a; // p now points to a[0]

I assume it works this way so that the array's contents can be accessed without copying all of them. That's just a behavior of array types and is not meant to imply that they are same thing.

Multidimensional arrays

Multidimensional arrays are just a way to 'partition' memory in a way that the compiler/machine can understand and operate on.

For instance, int a[4][3][5] = an array containing 4*3*5 (60) 'chunks' of integer-sized memory.

The advantage over using int a[4][3][5] vs plain int b[60] is that they're now 'partitioned' (Easier to work with their 'chunks', if needed), and the program can now perform bound checking.

In fact, int a[4][3][5] is stored exactly like int b[60] in memory - The only difference is that the program now manages it as if they're separate entities of certain sizes (Specifically, four groups of three groups of five).

Keep in mind: Both int a[4][3][5] and int b[60] are the same in memory, and the only difference is how they're handled by the application/compiler

{
  {1, 2, 3, 4, 5}
  {6, 7, 8, 9, 10}
  {11, 12, 13, 14, 15}
}
{
  {16, 17, 18, 19, 20}
  {21, 22, 23, 24, 25}
  {26, 27, 28, 29, 30}
}
{
  {31, 32, 33, 34, 35}
  {36, 37, 38, 39, 40}
  {41, 42, 43, 44, 45}
}
{
  {46, 47, 48, 49, 50}
  {51, 52, 53, 54, 55}
  {56, 57, 58, 59, 60}
}

From this, you can clearly see that each "partition" is just an array that the program keeps track of.

Syntax

Now, arrays are syntactically different from pointers. Specifically, this means the compiler/machine will treat them differently. This may seem like a no brainer, but take a look at this:

int a[3][3];

printf("%p %p", a, a[0]);

The above example prints the same memory address twice, like this:

0x7eb5a3b4 0x7eb5a3b4

However, only one can be assigned to a pointer so directly:

int *p1 = a[0]; // RIGHT !

int *p2 = a; // WRONG !

Why can't a be assigned to a pointer but a[0] can?

This, simply, is a consequence of multidimensional arrays, and I'll explain why:

At the level of 'a', we still see that we have another 'dimension' to look forward to. At the level of 'a[0]', however, we're already in the top dimension, so as far as the program is concerned we're just looking at a normal array.

You may be asking:

Why does it matter if the array is multidimensional in regards to making a pointer for it?

It's best to think this way:

A 'decay' from a multidimensional array is not just an address, but an address with partition data (AKA it still understands that its underlying data is made of other arrays), which consists of boundaries set by the array beyond the first dimension.

This 'partition' logic cannot exist within a pointer unless we specify it:

int a[4][5][95][8];

int (*p)[5][95][8];

p = a; // p = *a[0] // p = a+0

Otherwise, the meaning of the array's sorting properties are lost.

Also note the use of parenthesis around *p: int (*p)[5][95][8] - That's to specify that we're making a pointer with these bounds, not an array of pointers with these bounds: int *p[5][95][8]

Conclusion

Let's review:

• Arrays decay to addresses if they have no other purpose in the used context
• Multidimensional arrays are just arrays of arrays - Hence, the 'decayed' address will carry the burden of "I have sub dimensions"
• Dimension data cannot exist in a pointer unless you give it to it.

In brief: multidimensional arrays decay to addresses that carry the ability to understand their contents.

Whether to use a datepicker or not I think depends on how long ago the dates are. If they are typically in the current month, and almost never more than a few months old, and you know that Javascript will be around, a datepicker is good. If the dates are not recent (say, a birthdate) I think this is the best option:

Note that this is different from Patrick McElhaney's answer in that the year is a text box, not a dropdown. Selecting a number from a drop down box that is hundreds of elements long is very annoying for the user.

// Example
function ourRandomRange(ourMin, ourMax) {
    return Math.floor(Math.random() * (ourMax - ourMin + 1)) + ourMin;
}

ourRandomRange(1, 9);

// Only change code below this line.
function randomRange(myMin, myMax) {
    var a = Math.floor(Math.random() * (myMax - myMin + 1)) + myMin;
    return a; // Change this line
}

// Change these values to test your function
var myRandom = randomRange(5, 15);

1. You can also achieve this using the backreference technique

   sed -i.bak 's/\(.*\)/\1:80/' foo.txt
   

2. You can also use with awk like this

   awk '{print $0":80"}' foo.txt > tmp && mv tmp foo.txt

You can calculate with Dates.

var birthdate = new Date("1990/1/1");
var cur = new Date();
var diff = cur-birthdate; // This is the difference in milliseconds
var age = Math.floor(diff/31557600000); // Divide by 1000*60*60*24*365.25

function getKeyByValue(object, value) {
  return Object.keys(object).find(key => object[key] === value);
}

ES6, no prototype mutations or external libraries.

Example,

function getKeyByValue(object, value) {_x000D_
  return Object.keys(object).find(key => object[key] === value);_x000D_
}_x000D_
_x000D_
_x000D_
const map = {"first" : "1", "second" : "2"};_x000D_
console.log(getKeyByValue(map,"2"));

NOTE: Doesn't work on newer versions of jQuery.

Since you are using jQuery please use it's seralize function to serialize data and then pass it into the data parameter of ajax call:

info[0] = 'hi';
info[1] = 'hello';

var data_to_send = $.serialize(info);

$.ajax({
    type: "POST",
    url: "index.php",
    data: data_to_send,
    success: function(msg){
        $('.answer').html(msg);
    }
});

For single color foreground color

label.setForeground(Color.RED)

For multiple foreground colors in the same label:

(I would probably put two labels next to each other using a GridLayout or something, but here goes...)

You could use html in your label text as follows:

frame.add(new JLabel("<html>Text color: <font color='red'>red</font></html>"));

which produces:

.fa-file-o {
    position: absolute;
    left: 50px;
    top: 15px;
    color: #ffffff
}

<div>
 <span class="fa fa-file-o"></span>
 <input type="button" name="" value="IMPORT FILE"/>
</div>

They are parts of the Observer design pattern. Usually one or more obervers get informed about changes in one observable. It's a notifcation that "something" happened, where you as a programmer can define what "something" means.

When using this pattern, you decouple the both entities from each another - the observers become pluggable.

Your result will vary depending on what kind of terminal or console program you're on, but yes, on most \b is a nondestructive backspace. It moves the cursor backward, but doesn't erase what's there.

So for the hello worl part, the code outputs

hello worl
          ^

...(where ^ shows where the cursor is) Then it outputs two \b characters which moves the cursor backward two places without erasing (on your terminal):

hello worl
        ^

Note the cursor is now on the r. Then it outputs d, which overwrites the r and gives us:

hello wodl
         ^

Finally, it outputs \n, which is a non-destructive newline (again, on most terminals, including apparently yours), so the l is left unchanged and the cursor is moved to the beginning of the next line.

I am using Bootstrap v3.3.4 and using the code:

 $('.datepicker').datepicker({
    dateFormat: 'dd-mm-yy'
 });

Output is: 16-07-2015

Note: only need "yy" for full year.

The paths to readlink are different between my system and yours. Please try specifying the full path:

If you want to change MSSQL server language, you can use the following QUERY:

EXEC sp_configure 'default language', 'British English';

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

This worked for me

sudo apt install openjdk-8-jre-headless

If you want to first take mean on the combination of ['cluster', 'org'] and then take mean on cluster groups, you can use:

In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
            .groupby('cluster')['time'].mean())
Out[59]:
cluster
1          15
2          54
3           6
Name: time, dtype: int64

If you want the mean of cluster groups only, then you can use:

In [58]: df.groupby(['cluster']).mean()
Out[58]:
              time
cluster
1        12.333333
2        54.000000
3         6.000000

You can also use groupby on ['cluster', 'org'] and then use mean():

In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
               time
cluster org
1       a    438886
        c        23
2       d      9874
        h        34
3       w         6

No, Java doesn't have something like C#'s ref and out keywords for passing by reference.

You can only pass by value in Java. Even references are passed by value. See Jon Skeet's page about parameter passing in Java for more details.

To do something similar to ref or out you would have to wrap your parameters inside another object and pass that object reference in as a parameter.

The IServiceCollection interface is used for building a dependency injection container. After it's fully built, it gets composed to an IServiceProvider instance which you can use to resolve services. You can inject an IServiceProvider into any class. The IApplicationBuilder and HttpContext classes can provide the service provider as well, via their ApplicationServices or RequestServices properties respectively.

IServiceProvider defines a GetService(Type type) method to resolve a service:

var service = (IFooService)serviceProvider.GetService(typeof(IFooService));

There are also several convenience extension methods available, such as serviceProvider.GetService<IFooService>() (add a using for Microsoft.Extensions.DependencyInjection).

Resolving services inside the startup class

Injecting dependencies

The runtime's hosting service provider can inject certain services into the constructor of the Startup class, such as IConfiguration, IWebHostEnvironment (IHostingEnvironment in pre-3.0 versions), ILoggerFactory and IServiceProvider. Note that the latter is an instance built by the hosting layer and contains only the essential services for starting up an application.

The ConfigureServices() method does not allow injecting services, it only accepts an IServiceCollection argument. This makes sense because ConfigureServices() is where you register the services required by your application. However you can use services injected in the startup's constructor here, for example:

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

public IConfiguration Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    // Use Configuration here
}

Any services registered in ConfigureServices() can then be injected into the Configure() method; you can add an arbitrary number of services after the IApplicationBuilder parameter:

public void ConfigureServices(IServiceCollection services)
{
    services.AddScoped<IFooService>();
}

public void Configure(IApplicationBuilder app, IFooService fooService)
{
    fooService.Bar();
}

Manually resolving dependencies

If you need to manually resolve services, you should preferably use the ApplicationServices provided by IApplicationBuilder in the Configure() method:

public void Configure(IApplicationBuilder app)
{
    var serviceProvider = app.ApplicationServices;
    var hostingEnv = serviceProvider.GetService<IHostingEnvironment>();
}

It is possible to pass and directly use an IServiceProvider in the constructor of your Startup class, but as above this will contain a limited subset of services, and thus has limited utility:

public Startup(IServiceProvider serviceProvider)
{
    var hostingEnv = serviceProvider.GetService<IWebHostEnvironment>();
}

If you must resolve services in the ConfigureServices() method, a different approach is required. You can build an intermediate IServiceProvider from the IServiceCollection instance which contains the services which have been registered up to that point:

public void ConfigureServices(IServiceCollection services)
{
    services.AddSingleton<IFooService, FooService>();

    // Build the intermediate service provider
    var sp = services.BuildServiceProvider();

    // This will succeed.
    var fooService = sp.GetService<IFooService>();
    // This will fail (return null), as IBarService hasn't been registered yet.
    var barService = sp.GetService<IBarService>();
}

Please note: Generally you should avoid resolving services inside the ConfigureServices() method, as this is actually the place where you're configuring the application services. Sometimes you just need access to an IOptions<MyOptions> instance. You can accomplish this by binding the values from the IConfiguration instance to an instance of MyOptions (which is essentially what the options framework does):

public void ConfigureServices(IServiceCollection services)
{
    var myOptions = new MyOptions();
    Configuration.GetSection("SomeSection").Bind(myOptions);
}

Manually resolving services (aka Service Locator) is generally considered an anti-pattern. While it has its use-cases (for frameworks and/or infrastructure layers), you should avoid it as much as possible.

Jai is correct that you should use INSERT ... ON DUPLICATE KEY UPDATE.

Note that you do not need to include datenum in the update clause since it's the unique key, so it should not change. You do need to include all of the other columns from your table. You can use the VALUES() function to make sure the proper values are used when updating the other columns.

Here is your update re-written using the proper INSERT ... ON DUPLICATE KEY UPDATE syntax for MySQL:

INSERT INTO AggregatedData (datenum,Timestamp)
VALUES ("734152.979166667","2010-01-14 23:30:00.000")
ON DUPLICATE KEY UPDATE 
  Timestamp=VALUES(Timestamp)

With the help of spark-csv we can write to a CSV file.

val dfsql = sqlContext.sql("select * from tablename")
dfsql.write.format("com.databricks.spark.csv").option("header","true").save("output.csv")`

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

Below is a sample snippet code to lock a file until it's process is done by JVM.

 public static void main(String[] args) throws InterruptedException {
    File file = new File(FILE_FULL_PATH_NAME);
    RandomAccessFile in = null;
    try {
        in = new RandomAccessFile(file, "rw");
        FileLock lock = in.getChannel().lock();
        try {

            while (in.read() != -1) {
                System.out.println(in.readLine());
            }
        } finally {
            lock.release();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }finally {
        try {
            in.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

A table-cell can legitimately contain block-level elements so it's not, inherently, a faux-pas. Browser implentation, of course, leaves this a speculative-theoretical position. It may cause layout problems and bugs.

Though as tables were used for layout -and sometimes still are- I imagine that most browsers will render the content properly. Even IE.

You've got "Bad Status" its because the target file cannot find or not present, like for example you call README file which is not in the current directory.

This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...

The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.

I don't know if Boost has more specific functions, but you can do it with the standard library.

Given std::vector<double> v, this is the naive way:

#include <numeric>

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

double sq_sum = std::inner_product(v.begin(), v.end(), v.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size() - mean * mean);

This is susceptible to overflow or underflow for huge or tiny values. A slightly better way to calculate the standard deviation is:

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

std::vector<double> diff(v.size());
std::transform(v.begin(), v.end(), diff.begin(),
               std::bind2nd(std::minus<double>(), mean));
double sq_sum = std::inner_product(diff.begin(), diff.end(), diff.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size());

UPDATE for C++11:

The call to std::transform can be written using a lambda function instead of std::minus and std::bind2nd(now deprecated):

std::transform(v.begin(), v.end(), diff.begin(), [mean](double x) { return x - mean; });

Loop through divs every 10 seconds.

$(function () {

    var counter = 0,
        divs = $('#div1, #div2, #div3');

    function showDiv () {
        divs.hide() // hide all divs
            .filter(function (index) { return index == counter % 3; }) // figure out correct div to show
            .show('fast'); // and show it

        counter++;
    }; // function to loop through divs and show correct div

    showDiv(); // show first div    

    setInterval(function () {
        showDiv(); // show next div
    }, 10 * 1000); // do this every 10 seconds    

});

@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the + operator fails for strings in EL (which is correct), then just do:

<c:out value="abc${test}" />

Or if abc is to obtained from another scoped variable named ${resp}, then do:

<c:out value="${resp}${test}" />

You can expire Redis hashes in ease, Eg using python

import redis
conn = redis.Redis('localhost')
conn.hmset("hashed_user", {'name': 'robert', 'age': 32})
conn.expire("hashed_user", 10)

This will expire all child keys in hash hashed_user after 10 seconds

same from redis-cli,

127.0.0.1:6379> HMSET testt username wlc password P1pp0 age 34
OK
127.0.0.1:6379> hgetall testt
1) "username"
2) "wlc"
3) "password"
4) "P1pp0"
5) "age"
6) "34"
127.0.0.1:6379> expire testt 10
(integer) 1
127.0.0.1:6379> hgetall testt
1) "username"
2) "wlc"
3) "password"
4) "P1pp0"
5) "age"
6) "34"

after 10 seconds

You could use a cross-over ethernet cable - http://en.wikipedia.org/wiki/Ethernet_crossover_cable

Assuming your RPi is a DCHP Client, then best to run a simple DHCP server on your notebook to assign the RPi an IP address.

Another good option for handling this kind of option is the pprint module, which (among other things) pretty prints long lists with one element per line:

You can use finds null separated output option with read to iterate over directory structures safely.

#!/bin/bash
find . -type f -print0 | while IFS= read -r -d $'\0' file; 
  do echo "$file" ;
done

So for your case

#!/bin/bash
find . -maxdepth 1 -type f  -print0 | while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done

additionally

#!/bin/bash
while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done < <(find . -maxdepth 1 -type f  -print0)

will run the while loop in the current scope of the script ( process ) and allow the output of find to be used in setting variables if needed

    listItem.remove(position);
    ItemAdapter.notifyDataSetChanged();

}

The correct syntax is mysql> SET @@global.group_concat_max_len = integer;
If you do not have the privileges to do this on the server where your database resides then use a query like:
mySQL="SET @@session.group_concat_max_len = 10000;"or a different value.
Next line:
SET objRS = objConn.Execute(mySQL)  your variables may be different.
then
mySQL="SELECT GROUP_CONCAT(......);" etc
I use the last version since I do not have the privileges to change the default value of 1024 globally (using cPanel).
Hope this helps.

In my case, IntelliJ was simply in power safe mode

I'm going to assume you are using Web Site Projects. These automatically crawl their project directory and throw everything into source control. There's no way to stop them.

However, don't despair. Web Application Projects don't exhibit this strange and rather unexpected (imho: moronic) behavior. WAP is an addon on for VS2005 and comes direct with VS2008.

As an alternative to changing your projects to WAP, you might consider moving the Assets folder out of Source control and into a TFS Document Library. Only do this IF the project itself doesn't directly use the assets files.

wxLua has three sleep functions:

local wx = require 'wx'
wx.wxSleep(12)   -- sleeps for 12 seconds
wx.wxMilliSleep(1200)   -- sleeps for 1200 milliseconds
wx.wxMicroSleep(1200)   -- sleeps for 1200 microseconds (if the system supports such resolution)

public class X { static {
  System.out.println("Main not required to print this");
  System.exit(0);
}}

Run from the cmdline with java X.

You may choose to store the whole form as a JSON string.

Not sure about your requirement, but this approach would work in some circumstances.

In latest version (1.0RC) of TypeScript, you can use enums like this:

enum States {
    New,
    Active,
    Disabled
} 

// this will show message '0' which is number representation of enum member
alert(States.Active); 

// this will show message 'Disabled' as string representation of enum member
alert(States[States.Disabled]);

Update 1

To get number value of enum member from string value, you can use this:

var str = "Active";
// this will show message '1'
alert(States[str]);

Update 2

In latest TypeScript 2.4, there was introduced string enums, like this:

enum ActionType {
    AddUser = "ADD_USER",
    DeleteUser = "DELETE_USER",
    RenameUser = "RENAME_USER",

    // Aliases
    RemoveUser = DeleteUser,
}

For more info about TypeScript 2.4, read blog on MSDN.

In ES6 you can use Array.prototype.find(predicate, thisArg?) like so:

array.find(x => x.name === 'string 1')

http://exploringjs.com/es6/ch_arrays.html#_searching-for-array-elements https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find

To then replace said object (and use another cool ES6 method fill) you could do something like:

let obj = array.find(x => x.name === 'string 1');
let index = array.indexOf(obj);
array.fill(obj.name='some new string', index, index++);

If you're dealing with optional Strings, this works:

(string ?? "").isEmpty

The ?? nil coalescing operator returns the left side if it's non-nil, otherwise it returns the right side.

You can also use it like this to return a default value:

(string ?? "").isEmpty ? "Default" : string!

Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup

$("#div").html($("#input").val());

You can do it less code like below :

f = pd.DataFrame({'col1':[1,2,3,4,5], 'col2':list('abcab'),'col3':list('ababb')})

f['col1'] =f['col1'].astype('category').cat.codes
f['col2'] =f['col2'].astype('category').cat.codes
f['col3'] =f['col3'].astype('category').cat.codes

f

Had the same issue but mine was working for weeks before this. Realised I had changed my password on the server.

Remember to update your password if you've got the option selected 'Run whether user is logged on or not'

$('#modal').modal('hide'); and its variants did not work for me unless I had data-dismiss="modal" as an attribute on the Cancel button. Like you, my needs were to possibly close / possibly-not close based on some additional logic so clicking a link with data-dismiss="modal" outright would not do. I ended up having a hidden button with data-dismiss="modal" that I could programmatically invoke the click handler from, so

<a id="hidden-cancel" class="hide" data-dismiss="modal"></a>
<a class="close btn">Cancel</a>

and then inside the click handlers for cancel when you need to close the modal you can have

$('#hidden-cancel').click();

let VC1 = self.storyboard!.instantiateViewController(withIdentifier: "MyViewController") as! MyViewController
let navController = UINavigationController(rootViewController: VC1)
self.present(navController, animated:true, completion: nil)

If you want to search deleted record (Soft Deleted Record), do't user Eloquent Model Query. Instead use Db::table query e.g Instead of using Below:

$stu = Student::where('rollNum', '=', $rollNum . '-' . $nursery)->first();

Use:

$stu = DB::table('students')->where('rollNum', '=', $newRollNo)->first();

.. ELSE a.Country ...

I suppose

You can pass an array as the first AutoFilter argument and use the xlFilterValues operator.

This will display PDF, DOC and DOCX filetypes.

Criteria1:=Array(".pdf", ".doc", ".docx"), Operator:=xlFilterValues

One pragmatic tip: you can search easily for the static_cast keyword in your source code if you plan to tidy up the project.

try

el.css('margin-left',mrg+'px');

i had same issue and also a problem file icon in intellij, so i removed the .idea folder and re import project solved my issue.

The proper way of checking if array key exists is function array_key_exists()

The difference is that when you have $_POST['variable'] = null it means that key exists and was send but value was null

The other option is isset() which which will check if array key exists and if it was set

The last option is to use empty() which will check if array key exists if is set and if value is not considered empty.

Examples:

$arr = [
  'a' => null,
  'b' => '',
  'c' => 1
];

array_key_exists('a', $arr); // true
isset($arr['a']); // false
empty($arr['a']); // true


array_key_exists('b', $arr); // true
isset($arr['b']); // true
empty($arr['b']); // true


array_key_exists('c', $arr); // true
isset($arr['c']); // true
empty($arr['c']); // false

Regarding your question

The proper way to check if value was send is to use array_key_exists() with check of request method

if ($_SERVER['REQUEST_METHOD'] == 'POST' && array_key_exists('fromPerson', $_POST)    
{
   // logic
}

But there are some cases depends on your logic where isset() and empty() can be good as well.

You do know that DataRow is the row of a DataTable correct?

What you currently have already loop through each row. You just have to keep track of how many rows there are in order to get the current row.

int i = 0;
int index = 0;
foreach (DataRow row in dt.Rows) 
{
index = i;
// do stuff
i++;
} 

char sep = '\n'  /1\
; int i = 68    /1  \
; while (i  ---      1\
                       \
                       /1/1/1                               /1\
                                                            /1\
                                                            /1\
                                                            /1\
                                                            /1\
                            /           1\
                           /            1 \
                          /             1  \
                         /              1   \
                         /1            /1    \
                          /1          /1      \
                           /1        /1        /1/1> 0) std::cout \
                              <<i<<                               sep;

For larger numbers, C++20 introduces some more advanced looping features. First to catch i we can build an inverse loop-de-loop and deflect it onto the std::ostream. However, the speed of i is implementation-defined, so we can use the new C++20 speed operator <<i<< to speed it up. We must also catch it by building wall, if we don't, i leaves the scope and de referencing it causes undefined behavior. To specify the separator, we can use:

 std::cout \
           sep

and there we have a for loop from 67 to 1.

Perhaps this is what you are looking for:

import os
os.chdir(default_path)

For seperating using tabs instead of using println you can use print

ArrayList<String> mylist = new ArrayList<String>();

mylist.add("C Programming");
mylist.add("Java");
mylist.add("C++");
mylist.add("Perl");
mylist.add("Python");

for (String each : mylist)
{       
    System.out.print(each);
    System.out.print("\t");
}

Take a look at the log_errors configuration option in php.ini. It seems to do just what you want to. I think you can use the error_log option to set your own logging file too.

When the log_errors directive is set to On, any errors reported by PHP would be logged to the server log or the file specified with error_log. You can set these options with ini_set too, if you need to.

(Please note that display_errors should be disabled in php.ini if this option is enabled)

If you want repeatable fade animation you can do that by using CABasicAnimation like below :

First create handy UIView extension :

extension UIView {

    enum AnimationKeyPath: String {
        case opacity = "opacity"
    }

    func flash(animation: AnimationKeyPath ,withDuration duration: TimeInterval = 0.5, repeatCount: Float = 5){
        let flash = CABasicAnimation(keyPath: animation.rawValue)
        flash.duration = duration
        flash.fromValue = 1 // alpha
        flash.toValue = 0 // alpha
        flash.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        flash.autoreverses = true
        flash.repeatCount = repeatCount

        layer.add(flash, forKey: nil)
    }
}

How to use it:

    // You can use it with all kind of UIViews e.g. UIButton, UILabel, UIImage, UIImageView, ...
    imageView.flash(animation: .opacity, withDuration: 1, repeatCount: 5)
    titleLabel.flash(animation: .opacity, withDuration: 1, repeatCount: 5)

Event delegation is handling an event that bubbles using an event handler on a container element, but only activating the event handler's behavior if the event happened on an element within the container that matches a given condition. This can simplify handling events on elements within the container.

For instance, suppose you want to handle a click on any table cell in a big table. You could write a loop to hook up a click handler to each cell...or you could hook up a click handler on the table and use event delegation to trigger it only for table cells (and not table headers, or the whitespace within a row around cells, etc.).

It's also useful when you're going to be adding and removing elements from the container, because you don't have to worry about adding and removing event handlers on those elements; just hook the event on the container and handle the event when it bubbles.

Here's a simple example (it's intentionally verbose to allow for inline explanation): Handling a click on any td element in a container table:

// Handle the event on the container_x000D_
document.getElementById("container").addEventListener("click", function(event) {_x000D_
    // Find out if the event targeted or bubbled through a `td` en route to this container element_x000D_
    var element = event.target;_x000D_
    var target;_x000D_
    while (element && !target) {_x000D_
        if (element.matches("td")) {_x000D_
            // Found a `td` within the container!_x000D_
            target = element;_x000D_
        } else {_x000D_
            // Not found_x000D_
            if (element === this) {_x000D_
                // We've reached the container, stop_x000D_
                element = null;_x000D_
            } else {_x000D_
                // Go to the next parent in the ancestry_x000D_
                element = element.parentNode;_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
    if (target) {_x000D_
        console.log("You clicked a td: " + target.textContent);_x000D_
    } else {_x000D_
        console.log("That wasn't a td in the container table");_x000D_
    }_x000D_

Before going into the details of that, let's remind ourselves how DOM events work.

DOM events are dispatched from the document to the target element (the capturing phase), and then bubble from the target element back to the document (the bubbling phase). This graphic in the old DOM3 events spec (now superceded, but the graphic's still valid) shows it really well:

Not all events bubble, but most do, including click.

The comments in the code example above describe how it works. matches checks to see if an element matches a CSS selector, but of course you can check for whether something matches your criteria in other ways if you don't want to use a CSS selector.

That code is written to call out the individual steps verbosely, but on vaguely-modern browsers (and also on IE if you use a polyfill), you can use closest and contains instead of the loop:

var target = event.target.closest("td");
    console.log("You clicked a td: " + target.textContent);
} else {
    console.log("That wasn't a td in the container table");
}

Live Example:

// Handle the event on the container_x000D_
document.getElementById("container").addEventListener("click", function(event) {_x000D_
    var target = event.target.closest("td");_x000D_
    if (target && this.contains(target)) {_x000D_
        console.log("You clicked a td: " + target.textContent);_x000D_
    } else {_x000D_
        console.log("That wasn't a td in the container table");_x000D_
    }_x000D_

closest checks the element you call it on to see if it matches the given CSS selector and, if it does, returns that same element; if not, it checks the parent element to see if it matches, and returns the parent if so; if not, it checks the parent's parent, etc. So it finds the "closest" element in the ancestor list that matches the selector. Since that might go past the container element, the code above uses contains to check that if a matching element was found, it's within the container — since by hooking the event on the container, you've indicated you only want to handle elements within that container.

Going back to our table example, that means that if you have a table within a table cell, it won't match the table cell containing the table:

// Handle the event on the container_x000D_
document.getElementById("container").addEventListener("click", function(event) {_x000D_
    var target = event.target.closest("td");_x000D_
    if (target && this.contains(target)) {_x000D_
        console.log("You clicked a td: " + target.textContent);_x000D_
    } else {_x000D_
        console.log("That wasn't a td in the container table");_x000D_
    }_x000D_

There are certainly some weird characters (e.g. BOM) or some whitespace before the XML preamble (<?xml ...?>)?

The below worked for me..

in Dog.java

public Class Dog{

private String a,b;

public Dog(){} //no args constructor

public Dog(Dog d){ // copy constructor
   this.a=d.a;
   this.b=d.b;
}

}

 -------------------------

 private List<Dog> createCopy(List<Dog> dogs) {
 List<Dog> newDogsList= new ArrayList<>();
 if (CollectionUtils.isNotEmpty(dogs)) {
 dogs.stream().forEach(dog-> newDogsList.add((Dog) SerializationUtils.clone(dog)));
 }
 return newDogsList;
 }

Here the new list which got created from createCopy method is created through SerializationUtils.clone(). So any change made to new list will not affect original list

do this , please note that you will have to define the regex for 'test'!!!

string s = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
string[] parts = (new Regex("")).Split(s);
//just do a count on parts

For me, the problem happened because I first created a new AppID and then created a new app with the bundle identifier of the AppID in iTunes Connect, and then tried to connect my development app with the AppID from within Xcode.

In this case, Xcode assumed that the AppID has already been registered by someone.

To resolve the issue, you first change the bundle identifier in your app (in iTunes Connect's MyApp section) to some temporary values (or if you don't have any, create a dummy AppID such as com.yourcompany.testapp), delete the AppID in Certificates, Identifiers & Profiles page, and try connecting it from within Xcode, not from within Certificates, Identifiers & Profiles, by pushing the fixing issue button in Xcode.

I can recommend JavaScript Utility by Patrick J. O'Neil. It can obfuscate/compact and compress and it seems to be pretty good at these. That said, I never tried integrating it in a build script of any kind.

As for obfuscating vs. minifying - I am not a big fan of the former. It makes debugging impossible (Error at line 1... "wait, there is only one line") and they always take time to unpack. But if you need to... well.

Using this object --> TinyDB--Android-Shared-Preferences-Turbo its very simple. you can save most of the commonly used objects with it like arrays, integer, strings lists etc

Logically.

The presence of a private setter is because you can use auto property:

public int MyProperty { get; set; }

What would you do if you want to make it readonly?

public int MyProperty { get; }

Oh crap!! I can't access it from my own class; I should create it like a normal property:

private int myProperty;
public int MyProperty { get { return myProperty; } }

Hmm... but I lost the "Auto Property" feature...

public int MyProperty { get; private set; }

AHHH.. that is better!!

The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.

This explains the "strange results".

"Better" results can be obtained using the expressions below:

//*[text() = 'qwerty']

The above selects every element in the document that has at least one text-node child with value 'qwerty'.

//*[text() = 'qwerty' and not(text()[2])]

The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.

I have a decent example in jQuery AJAX and ASMX on using the jQuery AJAX call with asmx web services...

There is a line of code to uncommment in order to have it return JSON.

If in the lower right corner it says "2 processes running..." or similar, you may just need to wait for that to finish, since it may take time to download all the jars.

You could use startOf('day') method to compare just the date

Example :

var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());

dateToCompare.startOf('day').isSame(today.startOf('day'));

This answer didn't work for me, but I found the answer myself. No one, however, has posted my question. I'm too lazy to ask it and then answer it, so will just put it here.

This is for the following query:

data = Leaderboard.objects.filter(id=custom_user.id).values(
    'value1',
    'value2',
    'value3')

In template:

{% for dictionary in data %}
  {% for key, value in dictionary.items %}
    <p>{{ key }} : {{ value }}</p>
  {% endfor %}
{% endfor %}

Just type

document.querySelector('video').playbackRate = 1.25;

in JS console of your modern browser.

Sometimes you just need to recreate new device

I believe you're looking for HttpServerUtility.UrlEncode.

System.Web.HttpUtility.UrlEncode(string url)

This question already has a great answer but in the spirit of exploring all possibilities here is another technique to reorder dom elements whilst still allowing them to take up their space, unlike the absolute positioning method.

This method works in all modern browsers and IE9+ (basically any browser that supports display:table) it has a drawback that it can only be used on a max of 3 siblings though.

//the html    
<div class='container'>
    <div class='div1'>1</div>
    <div class='div2'>2</div>
    <div class='div3'>3</div>
</div>

//the css
.container {
   display:table;    
}
.div1 {
    display:table-footer-group;
}
.div2 {
    display:table-header-group;
}
.div3 {
    display:table-row-group;
}

This will reorder the elements from 1,2,3 to 2,3,1. Basically anything with the display set to table-header-group will be positioned at the top and table-footer-group at the bottom. Naturally table-row-group puts an element in the middle.

This method is quick with good support and requires much less css than the flexbox approach so if you are only looking to swap a few items around for a mobile layout for example then dont rule out this technique.

You can check out a live demo on codepen: http://codepen.io/thepixelninja/pen/eZVgLx

In Swift 4 and Swift 3, To convert String to URL:

URL(string: String)

or,

URL.init(string: "yourURLString")

And to convert URL to String:

URL.absoluteString

The one below converts the 'contents' of the url to string

String(contentsOf: URL)

This is how I got it to work cross browser using a combination of the methods above (I also needed to insert images dynamically into the dom):

$('#domTarget').html('<img src="" />');

var url = '/some/image/path.png';

$('#domTarget img').load(function(){}).attr('src', url).error(function() {
    if ( isIE ) {
       var thisImg = this;
       setTimeout(function() {
          if ( ! thisImg.complete ) {
             $(thisImg).attr('src', '/web/css/img/picture-broken-url.png');
          }
       },250);
    } else {
       $(this).attr('src', '/web/css/img/picture-broken-url.png');
    }
});

Note: You will need to supply a valid boolean state for the isIE variable.

This seems to work with pywin32 on windows 7

my_thread = threading.Thread()
my_thread.start()
my_thread._Thread__stop()

Also simple and easy:

Start-Sleep 10

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

Since Python is open source you can read the source code.

To find out what file a particular module or function is implemented in you can usually print the __file__ attribute. Alternatively, you may use the inspect module, see the section Retrieving Source Code in the documentation of inspect.

For built-in classes and methods this is not so straightforward since inspect.getfile and inspect.getsource will return a type error stating that the object is built-in. However, many of the built-in types can be found in the Objects sub-directory of the Python source trunk. For example, see here for the implementation of the enumerate class or here for the implementation of the list type.

So Nodejs comes with the default global variable called '__fileName' that holds the current file being executed My advice is to pass the __fileName to a service from any file , so that the retrieval of the fileName is made dynamic

Below, I make use of the fileName string and then split it based on the path.sep. Note path.sep avoids issues with posix file seperators and windows file seperators (issues with '/' and '\'). It is much cleaner. Getting the substring and getting only the last seperated name and subtracting it with the actulal length by 3 speaks for itself.

You can write a service like this (Note this is in typescript , but you can very well write it in js )

export class AppLoggingConstants {

    constructor(){

    }
      // Here make sure the fileName param is actually '__fileName'
    getDefaultMedata(fileName: string, methodName: string) {
        const appName = APP_NAME;
        const actualFileName = fileName.substring(fileName.lastIndexOf(path.sep)+1, fileName.length - 3);
        //const actualFileName = fileName;
     return appName+ ' -- '+actualFileName;
    }


}

export const AppLoggingConstantsInstance = new AppLoggingConstants();

When you shift right 2 bits you drop the 2 least significant bits. So:

x = 00101011

x >> 2

// now (notice the 2 new 0's on the left of the byte)
x = 00001010

This is essentially the same thing as dividing an int by 2, 2 times.

In Java

byte b = (byte) 16;
b = b >> 2;
// prints 4
System.out.println(b);

To simply list the commits waiting to be pushed: (this is the one you will remember)

git cherry -v

Show the commit subjects next to the SHA1s.

If you want rounded corner of UI objects like (UILabel, UIView, UIButton, UIImageView) by storyboard then set clip to bounds true and set User Defined Runtime Attributes Key path as layer.cornerRadius, type = Number and value = 9 (as your requirement)

Watch out for certain headers such as HTTP_X_FORWARDED_FOR that appear to contain a single IP address. They may actually contain multiple addresses (a chain of proxies I assume).

They will appear to be comma delimited - and can be a lot longer than 45 characters total - so check before storing in DB.

It's not at all clear what you're up to. Your function getAll() should return a List<Car>, not a Car. Otherwise, why call it getAll?

If you have

Car[] arrayOfCars

and want a List, you can simply do this:

List<Car> listOfCars = Arrays.asList(arrayOfCars);

Arrays is documented Here.

You may be interested in this question (or this one), which highlights the fact that identifying valid email addresses via regexps is a very hard problem to solve (if at all solvable)

I was working on Azure SQL server .For storing the data i used table values param like

  DECLARE @INTERMEDIATE_TABLE3 TABLE {
   x int;
 }

I discovered the error in writing on the queries

SELECT
      *
    FROM [@INTERMEDIATE_TABLE3]
    WHERE [@INTERMEDIATE_TABLE3].[ConsentDefinitionId] = 3

while quering the colomns ,its okay to wrap it with brabces like [@INTERMEDIATE_TABLE3].[ConsentDefinitionId] but when refering just the table valued param ,there shoul be no params.So it should be used as @INTERMEDIATE_TABLE3

So the code now must be changed to

SELECT
      *
    FROM @INTERMEDIATE_TABLE3
    WHERE [@INTERMEDIATE_TABLE3].[ConsentDefinitionId] =3.

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

Actually this is better way to do that. If height: 100% is used, the content goes off the border, but when it is 95% everything is in order:

div#scrollable {
    overflow-y: scroll;
    height: 95%;
}

HTML5 has a built-in combo box. You create a text input and a datalist. Then you add a list attribute to the input, with a value of the id of the datalist.

Update: As of March 2019 all major browsers (now including Safari 12.1 and iOS Safari 12.3) support datalist to the level needed for this functionality. See caniuse for detailed browser support.

It looks like this:

<input type="text" list="cars" />_x000D_
<datalist id="cars">_x000D_
  <option>Volvo</option>_x000D_
  <option>Saab</option>_x000D_
  <option>Mercedes</option>_x000D_
  <option>Audi</option>_x000D_
</datalist>

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

The differences are listed in the Javadoc for ListIterator

You can

• iterate backwards
• obtain the iterator at any point.
• add a new value at any point.
• set a new value at that point.

I had the same problem. mysql -u root -p worked for me. It later asks you for a password. You should then enter the password that you had set for mysql. The default password could be password, if you did not set one. More info here.

It's funny I spend the day investigating possibility to solve the same case. I found that it not possible doing this way:

// a.ts - module
export interface A {
    x: string | any;
}

// b.ts - module
import {A} from './a';

type SomeOtherType = {
  coolStuff: number
}

interface B extends A {
    x: SomeOtherType;
}

Cause A module may not know about all available types in your application. And it's quite boring port everything from everywhere and doing code like this.

export interface A {
    x: A | B | C | D ... Million Types Later
}

You have to define type later to have autocomplete works well.

So you can cheat a bit:

// a.ts - module
export interface A {
    x: string;
}

Left the some type by default, that allow autocomplete works, when overrides not required.

Then

// b.ts - module
import {A} from './a';

type SomeOtherType = {
  coolStuff: number
}

// @ts-ignore
interface B extends A {
    x: SomeOtherType;
}

Disable stupid exception here using @ts-ignore flag, saying us the we doing something wrong. And funny thing everything works as expected.

In my case I'm reducing the scope vision of type x, its allow me doing code more stricted. For example you have list of 100 properties, and you reduce it to 10, to avoid stupid situations

how about just getting the length of char in your EditText and display it?

something along the line of

tv.setText(s.length() + " / " + String.valueOf(charCounts));

I know that this question is about 6+ years old, but the answer by @Kyle doesn't work.

Using this

setSize(width - (getInsets().left + getInsets().right), height - (getInsets().top + getInsets().bottom));

But this always work in any size:

setSize(width + 14, height + 7);

If you don't want the border to border, and only want the white area, here:

setSize(width + 16, height + 39);

Also this only works on Windows 10, for MacOS users, use @ben's answer.

One more way of getting minutes and hours is by using SimpleDateFormat.

SimpleDateFormat formatMinutes = new SimpleDateFormat("mm")
String getMinutes = formatMinutes.format(new Date())

SimpleDateFormat formatHours = new SimpleDateFormat("HH")
String getHours = formatHours.format(new Date())

The keyword simply pops a frame from the call stack returning the control to the line following the function call.

I would think it could still be quite RESTful to have query arguments that identify the resource on the URL while keeping the content payload confined to the POST body. This would seem to separate the considerations of "What am I sending?" versus "Who am I sending it to?".

describe formatted <table_name>; inside hive shell.

Notice the "Location" value that shows the location of the table.

format supports a percentage floating point precision type:

>>> print "{0:.0%}".format(1./3)
33%

If you don't want integer division, you can import Python3's division from __future__:

>>> from __future__ import division
>>> 1 / 3
0.3333333333333333

# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%

# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%

Try this:

import os
import sys

Zeichen=["a","b","c","d","e","f","g","h"­,"i","j","k","l","m","n","o","p","q­","r","s","­;t","u","v","w","x","y","z"]

Lots of the above helped for me, plus the accepted answer, but since I was on an EC2 instance, I had no idea what my instance name was. Finally, I opened SQLServer Configuration Manager and in the Name column, use whatever is there as your connection server, so in my case, .\EC2SQLEXPRESS and worked great!

Your selector is wrong, you were probably looking for

$('select option:nth-child(1)')

This will work also:

$('select option:first-child')

Check out the DoWorkEventArgs.Argument Property:

...
backgroundWorker1.RunWorkerAsync(yourInt);
...

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    // Do not access the form's BackgroundWorker reference directly.
    // Instead, use the reference provided by the sender parameter.
    BackgroundWorker bw = sender as BackgroundWorker;

    // Extract the argument.
    int arg = (int)e.Argument;

    // Start the time-consuming operation.
    e.Result = TimeConsumingOperation(bw, arg);

    // If the operation was canceled by the user, 
    // set the DoWorkEventArgs.Cancel property to true.
    if (bw.CancellationPending)
    {
        e.Cancel = true;
    }
}

I agree John M has best answer to OP's question. Thought not explictly stated, the apparent purpose is to get a selected file name, whereas other answers return either counts or lists. I would add, however, that the msofiledialogfilepicker might be a better option in this case. ie:

Dim f As object
Set f = Application.FileDialog(msoFileDialogFilePicker)
dim varfile as variant 
f.show
with f
    .allowmultiselect = false
     for each varfile in .selecteditems
        msgbox varfile
     next varfile
end with

Note: the value of varfile will remain the same since multiselect is false (only one item is ever selected). I used its value outside the loop with equal success. It's probably better practice to do it as John M did, however. Also, the folder picker can be used to get a selected folder. I always prefer late binding, but I think the object is native to the default access library, so it may not be necessary here

Nope, BeautifulSoup, by itself, does not support XPath expressions.

An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.

Once you've parsed your document into an lxml tree, you can use the .xpath() method to search for elements.

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen
from lxml import etree

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)

There is also a dedicated lxml.html() module with additional functionality.

Note that in the above example I passed the response object directly to lxml, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests library, you want to set stream=True and pass in the response.raw object after enabling transparent transport decompression:

import lxml.html
import requests

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)

Of possible interest to you is the CSS Selector support; the CSSSelector class translates CSS statements into XPath expressions, making your search for td.empformbody that much easier:

from lxml.cssselect import CSSSelector

td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
    # Do something with these table cells.

Coming full circle: BeautifulSoup itself does have very complete CSS selector support:

for cell in soup.select('table#foobar td.empformbody'):
    # Do something with these table cells.

Make sure your packaging strategy defined in your pom.xml is not "pom". It should be "jar" or anything else. Once you do that, update your project right clicking on it and go to Maven -> Update Project...

XAND I have not heard of.

Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later

//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);

//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);

//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;

Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:

boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) { 
  //14: (###) ###-####
  //eliminate every char except 0-9
  str = str.replaceAll("[^0-9]", "");

  //remove leading 1 if it's there
  if (str.length() == 11) str = str.replaceAll("^1", "");

  isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));

On ASP.net web forms use in the @page AspCompat="true", add the system.windows.forms to you project. At your web.config add:

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="false" />
  </appSettings>

Then you can use:

Clipboard.SetText(CreateDescription());

I prefer to avoid using Ajax.BeginForm helper and do an Ajax call with JQuery. In my experience it is easier to maintain code written like this. So below are the details:

Models

public class ManagePeopleModel
{
    public List<PersonModel> People { get; set; }
    ... any other properties
}

public class PersonModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
    ... any other properties
}

Parent View

This view contains the following things:

• records of people to iterate through
• an empty div that will be populated with a modal when a Person needs to be edited
• some JavaScript handling all ajax calls

@model ManagePeopleModel

<h1>Manage People</h1>

@using(var table = Html.Bootstrap().Begin(new Table()))
{
    foreach(var person in Model.People)
    {
        <tr>
            <td>@person.Id</td>
            <td>@Person.Name</td>
            <td>@person.Age</td>
            <td>@html.Bootstrap().Button().Text("Edit Person").Data(new { @id = person.Id }).Class("btn-trigger-modal")</td>
        </tr>
    }
}

@using (var m = Html.Bootstrap().Begin(new Modal().Id("modal-person")))
{

}

@section Scripts
{
    <script type="text/javascript">
        // Handle "Edit Person" button click.
        // This will make an ajax call, get information for person,
        // put it all in the modal and display it
        $(document).on('click', '.btn-trigger-modal', function(){
            var personId = $(this).data('id');
            $.ajax({
                url: '/[WhateverControllerName]/GetPersonInfo',
                type: 'GET',
                data: { id: personId },
                success: function(data){
                    var m = $('#modal-person');
                    m.find('.modal-content').html(data);
                    m.modal('show');
                }
            });
        });

        // Handle submitting of new information for Person.
        // This will attempt to save new info
        // If save was successful, it will close the Modal and reload page to see updated info
        // Otherwise it will only reload contents of the Modal
        $(document).on('click', '#btn-person-submit', function() {
            var self = $(this);
            $.ajax({
                url: '/[WhateverControllerName]/UpdatePersonInfo',
                type: 'POST',
                data: self.closest('form').serialize(),
                success: function(data) {
                    if(data.success == true) {
                        $('#modal-person').modal('hide');
                        location.reload(false)
                    } else {
                        $('#modal-person').html(data);
                    }
                }
            });
        });
    </script>
}

Partial View

This view contains a modal that will be populated with information about person.

@model PersonModel
@{
    // get modal helper
    var modal = Html.Bootstrap().Misc().GetBuilderFor(new Modal());
}

@modal.Header("Edit Person")
@using (var f = Html.Bootstrap.Begin(new Form()))
{
    using (modal.BeginBody())
    {
        @Html.HiddenFor(x => x.Id)
        @f.ControlGroup().TextBoxFor(x => x.Name)
        @f.ControlGroup().TextBoxFor(x => x.Age)
    }
    using (modal.BeginFooter())
    {
        // if needed, add here @Html.Bootstrap().ValidationSummary()
        @:@Html.Bootstrap().Button().Text("Save").Id("btn-person-submit")
        @Html.Bootstrap().Button().Text("Close").Data(new { dismiss = "modal" })
    }
}

Controller Actions

public ActionResult GetPersonInfo(int id)
{
    var model = db.GetPerson(id); // get your person however you need
    return PartialView("[Partial View Name]", model)
}

public ActionResult UpdatePersonInfo(PersonModel model)
{
    if(ModelState.IsValid)
    {
        db.UpdatePerson(model); // update person however you need
        return Json(new { success = true });
    }
    // else
    return PartialView("[Partial View Name]", model);
}

There are many realizations of hash functions written in JS. For example:

• SHA-1: http://www.webtoolkit.info/javascript-sha1.html
• SHA-256: http://www.webtoolkit.info/javascript-sha256.html
• MD5: http://www.webtoolkit.info/javascript-md5.html

If you don't need security, you can also use base64 which is not hash-function, has not fixed output and could be simply decoded by user, but looks more lightweight and could be used for hide values: http://www.webtoolkit.info/javascript-base64.html

Only need to fill datagrid again like this:

this.XXXTableAdapter.Fill(this.DataSet.XXX);

If you use automaticlly connect from dataGridView this code create automaticlly in Form_Load()

I normally use the HttpPostedFileBase parameter only in Mvc Controllers. When dealing with ApiControllers try checking the HttpContext.Current.Request.Files property for incoming files instead:

[HttpPost]
public string UploadFile()
{
    var file = HttpContext.Current.Request.Files.Count > 0 ?
        HttpContext.Current.Request.Files[0] : null;

    if (file != null && file.ContentLength > 0)
    {
        var fileName = Path.GetFileName(file.FileName);

        var path = Path.Combine(
            HttpContext.Current.Server.MapPath("~/uploads"),
            fileName
        );

        file.SaveAs(path);
    }

    return file != null ? "/uploads/" + file.FileName : null;
}

First create an object of class2 in class1 and then use that object to call any function of class2 for example write this in class1

class2 obj= new class2();
obj.thefunctioname(args);

The regex for uuid is:

\b[0-9a-f]{8}\b-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-\b[0-9a-f]{12}\b

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

I was scratching my head about this for a while too, and since Dave's explanation is a little hard to understand I'll post my (apparently working) code:

private class TabListener<T extends Fragment> implements ActionBar.TabListener {
    private Fragment mFragment;
    private Activity mActivity;
    private final String mTag;
    private final Class<T> mClass;

    public TabListener(Activity activity, String tag, Class<T> clz) {
        mActivity = activity;
        mTag = tag;
        mClass = clz;
        mFragment=mActivity.getFragmentManager().findFragmentByTag(mTag);
    }

    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        if (mFragment == null) {
            mFragment = Fragment.instantiate(mActivity, mClass.getName());
            ft.replace(android.R.id.content, mFragment, mTag);
        } else {
            if (mFragment.isDetached()) {
                ft.attach(mFragment);
            }
        }
    }

    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        if (mFragment != null) {
            ft.detach(mFragment);
        }
    }

    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }
}

As you can see it's pretty much like the Android sample, apart from not detaching in the constructor, and using replace instead of add.

After much headscratching and trial-and-error I found that finding the fragment in the constructor seems to make the double onCreateView problem magically go away (I assume it just ends up being null for onTabSelected when called through the ActionBar.setSelectedNavigationItem() path when saving/restoring state).

I've been having this same problem for over a day now - finally figured it out. Thanks to @Sameh for the hint.

Your service is probably working just fine. Testing POST messages using the address bar of a browser won't work. You need to use Fiddler to test a POST message.

Fiddler instructions... http://www.ehow.com/how_8788176_do-post-using-fiddler.html

I've just created a little example showing how to implement commands in convention over configuration style. However it requires Reflection.Emit() to be available. The supporting code may seem a little weird but once written it can be used many times.

Teaser:

public class SampleViewModel: BaseViewModelStub
{
    public string Name { get; set; }

    [UiCommand]
    public void HelloWorld()
    {
        MessageBox.Show("Hello World!");
    }

    [UiCommand]
    public void Print()
    {
        MessageBox.Show(String.Concat("Hello, ", Name, "!"), "SampleViewModel");
    }

    public bool CanPrint()
    {
        return !String.IsNullOrEmpty(Name);
    }
}

}

UPDATE: now there seem to exist some libraries like http://www.codeproject.com/Articles/101881/Executing-Command-Logic-in-a-View-Model that solve the problem of ICommand boilerplate code.

It may be relevant to see if it's running in PHP via command line as well-

<path-to-php-binary>php -i | grep memcache

In my case this was what helped me. I'm supporting ios6 also.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    self.edgesForExtendedLayout = UIRectEdgeNone;
    self.extendedLayoutIncludesOpaqueBars = NO;
    self.automaticallyAdjustsScrollViewInsets = NO;
}

First, your HTML markup looks like this:

<video id="awesome_video" src="first_video.mp4" autoplay />

Second, your JavaScript code will look like this:

<script type="text/javascript">
  var index = 1,
      playlist = ['first_video.mp4', 'second_video.mp4', 'third_video.mp4'],
      video = document.getElementById('awesome_video');

  video.addEventListener('ended', rotate_video, false);

  function rotate_video() {
    video.setAttribute('src', playlist[index]);
    video.load();
    index++;
    if (index >= playlist.length) { index = 0; }
  }
</script>

And last but not least, your CSS:

#awesome_video { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

This will create a video element on your page that starts playing the first video right away, then iterates through the playlist defined by the JavaScript variable. Your mileage with the CSS may vary depending on the CSS for the rest of the site, but 100% width/height should do it on a basic page.

Other than what Alex and Evan have already stated, I would like to add that a C++ struct is not like a C struct.

In C++, a struct can have methods, inheritance, etc. just like a C++ class.

I formerly voted to close this question as off-topic but actually I changed my mind as this is quite nice visual effect which, unfortunately, is not yet part of support library. It will most likely show up in future update, but there's no time frame announced.

Luckily there are few custom implementations already available:

• https://github.com/traex/RippleEffect
• https://github.com/balysv/material-ripple
• https://github.com/siriscac/RippleView
• https://github.com/ozodrukh/RippleDrawable

including Materlial themed widget sets compatible with older versions of Android:

• https://github.com/keithellis/MaterialWidget

so you can try one of these or google for other "material widgets" or so...

I had the same problem. I tried everything listed on this page. When I re-installed Composer it worked like before. I had a PHP version mismatch that was corrected with a new install establishing the dependencies with the PHP path installed in my system environment variables.

I DO NOT RECOMMEND the composer config -g -- disable-tls true approach.

By the way the way to reverse this is composer config -g -- disable-tls false.

2019 Update

This updates the answers with the latest Fetch API and doesn't need jQuery.

Disclaimer: doesn't work on IE, Opera Mini and older browsers. See caniuse.

Basic Fetch

It could be as simple as:

  fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
                .then(response => console.log(response.text()))

Fetch with Error Handling

After adding error handling, it could look like:

fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
            .then(response => {
                if (response.ok) return response;
                else throw Error(`Server returned ${response.status}: ${response.statusText}`)
            })
            .then(response => console.log(response.text()))
            .catch(err => {
                alert(err);
            });

PHP Code

This is the server-side code in upload.php.

<?php    
    // gets entire POST body
    $data = file_get_contents('php://input');
    // write the data out to the file
    $fp = fopen("path/to/file", "wb");

    fwrite($fp, $data);
    fclose($fp);
?>

In node, the Mongo driver will give you an ISO string, not the object. (ex: Mon Nov 24 2014 01:30:34 GMT-0800 (PST)) So, simply convert it to a js Date by: new Date(ISOString);

Use the Filter() method as shown here - https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/filter-function

If the enum index is 0-based, you can put the names in an array of char*, and index them with the enum value.

I can imagine following advantages of having a class method defined as static one:

• you can call the method just using class name, no need to instantiate it.

remaining advantages are probably marginal if present at all:

• might run a bit faster
• save a bit of memory

That error usually occurs when you try to subtract an interval from DateTime.MinValue or you want to add something to DateTime.MaxValue (or you try to instantiate a date outside this min-max interval). Are you sure you're not assigning MinValue somewhere?

I have just solve this problem in my Mac OS X, it is not about device driver or device cable.

You must enable "developer options" and enable "USB debugging"

For reference, here is a minimal implementation using Java 8 :

@Override
public void start(Stage mainStage) throws Exception {

    Scene scene = new Scene(new Region());
    mainStage.setWidth(640);
    mainStage.setHeight(480);
    mainStage.setScene(scene);

    //this makes all stages close and the app exit when the main stage is closed
    mainStage.setOnCloseRequest(e -> Platform.exit());

    //add real stuff to the scene...
    //open secondary stages... etc...
}

• Creation var div = document.createElement('div');
• Addition document.body.appendChild(div);
• Style manipulation
  • Positioning div.style.left = '32px'; div.style.top = '-16px';
  • Classes div.className = 'ui-modal';
• Modification
  • ID div.id = 'test';
  • contents (using HTML) div.innerHTML = '<span class="msg">Hello world.</span>';
  • contents (using text) div.textContent = 'Hello world.';
• Removal div.parentNode.removeChild(div);
• Accessing
  • by ID div = document.getElementById('test');
  • by tags array = document.getElementsByTagName('div');
  • by class array = document.getElementsByClassName('ui-modal');
  • by CSS selector (single) div = document.querySelector('div #test .ui-modal');
  • by CSS selector (multi) array = document.querySelectorAll('div');
• Relations (text nodes included)
  • children node = div.childNodes[i];
  • sibling node = div.nextSibling;
• Relations (HTML elements only)
  • children element = div.children[i];
  • sibling element = div.nextElementSibling;

This covers the basics of DOM manipulation. Remember, element addition to the body or a body-contained node is required for the newly created node to be visible within the document.

Above answers are good but If you do not want to add string include, you can use the following

ostream& operator<<(ostream& os, string& msg)
{
os<<msg.c_str();

return os;
}

You can find some technical comparison on npmcompare

Comparing browserify vs. grunt vs. gulp vs. webpack

As you can see webpack is very well maintained with a new version coming out every 4 days on average. But Gulp seems to have the biggest community of them all (with over 20K stars on Github) Grunt seems a bit neglected (compared to the others)

So if need to choose one over the other i would go with Gulp

Well Facebook has undergone MANY many changes and it wasn't originally designed to be efficient. It was designed to do it's job. I have absolutely no idea what the code looks like and you probably won't find much info about it (for obvious security and copyright reasons), but just take a look at the API. Look at how often it changes and how much of it doesn't work properly, anymore, or at all.

I think the biggest ace up their sleeve is the Hiphop. http://developers.facebook.com/blog/post/358 You can use HipHop yourself: https://github.com/facebook/hiphop-php/wiki

But if you ask me it's a very ambitious and probably time wasting task. Hiphop only supports so much, it can't simply convert everything to C++. So what does this tell us? Well, it tells us that Facebook is NOT fully taking advantage of the PHP language. It's not using the latest 5.3 and I'm willing to bet there's still a lot that is PHP 4 compatible. Otherwise, they couldn't use HipHop. HipHop IS A GOOD IDEA and needs to grow and expand, but in it's current state it's not really useful for that many people who are building NEW PHP apps.

There's also PHP to JAVA via things like Resin/Quercus. Again, it doesn't support everything...

Another thing to note is that if you use any non-standard PHP module, you aren't going to be able to convert that code to C++ or Java either. However...Let's take a look at PHP modules. They are ARE compiled in C++. So if you can build PHP modules that do things (like parse XML, etc.) then you are basically (minus some interaction) working at the same speed. Of course you can't just make a PHP module for every possible need and your entire app because you would have to recompile and it would be much more difficult to code, etc.

However...There are some handy PHP modules that can help with speed concerns. Though at the end of the day, we have this awesome thing known as "the cloud" and with it, we can scale our applications (PHP included) so it doesn't matter as much anymore. Hardware is becoming cheaper and cheaper. Amazon just lowered it's prices (again) speaking of.

So as long as you code your PHP app around the idea that it will need to one day scale...Then I think you're fine and I'm not really sure I'd even look at Facebook and what they did because when they did it, it was a completely different world and now trying to hold up that infrastructure and maintain it...Well, you get things like HipHop.

Now how is HipHop going to help you? It won't. It can't. You're starting fresh, you can use PHP 5.3. I'd highly recommend looking into PHP 5.3 frameworks and all the new benefits that PHP 5.3 brings to the table along with the SPL libraries and also think about your database too. You're most likely serving up content from a database, so check out MongoDB and other types of databases that are schema-less and document-oriented. They are much much faster and better for the most "common" type of web site/app.

Look at NEW companies like Foursquare and Smugmug and some other companies that are utilizing NEW technology and HOW they are using it. For as successful as Facebook is, I honestly would not look at them for "how" to build an efficient web site/app. I'm not saying they don't have very (very) talented people that work there that are solving (their) problems creatively...I'm also not saying that Facebook isn't a great idea in general and that it's not successful and that you shouldn't get ideas from it....I'm just saying that if you could view their entire source code, you probably wouldn't benefit from it.

Do it like this:

var value = $("#text").val(); // value = 9.61 use $("#text").text() if you are not on select box...
value = value.replace(".", ":"); // value = 9:61
// can then use it as
$("#anothertext").val(value);

Updated to reflect to current version of jQuery. And also there are a lot of answers here that would best fit to any same situation as this. You, as a developer, need to know which is which.

Replace all occurrences

To replace multiple characters at a time use some thing like this: name.replace(/&/g, "-"). Here I am replacing all & chars with -. g means "global"

Note - you may need to add square brackets to avoid an error - title.replace(/[+]/g, " ")

If you don't "care" about the data you can just do something like:

search_params = params[:search].valid_encoding? ? params[:search].gsub(/\W+/, '') : "nothing"

I just used valid_encoding? to get passed it. Mine is a search field, and so i was finding the same weirdness over and over so I used something like: just to have the system not break. Since i don't control the user experience to autovalidate prior to sending this info (like auto feedback to say "dummy up!") I can just take it in, strip it out and return blank results.

If you are working over boot projects and you wanna configure the port you can give the input in the application.properties file like NOTE:properties file should be under src/main/resource

Spring properties

server.port=9999 If you using the CMD then follow this command -Dserver.port=9999 For default port its server.port=0 Make sure no port is using this port number

By using itemStateChanged(ItemListener) you can track selecting and deselecting checkbox (and do whatever you want based on it):

myCheckBox.addItemListener(new ItemListener() {
    @Override
    public void itemStateChanged(ItemEvent e) {
        if(e.getStateChange() == ItemEvent.SELECTED) {//checkbox has been selected
            //do something...
        } else {//checkbox has been deselected
            //do something...
        };
    }
});

Java Swing itemStateChanged docu should help too. By using isSelected() method you can just test if actual is checkbox selected:

if(myCheckBox.isSelected()){_do_something_if_selected_}

You can use Twilio for this. But if you are looking for some tricky workaround you can follow the workaround I have mentioned below.

This is not possible for receiving sms. But this is a tricky method you can use to send sms to number of clients. You can use twitter API. We can follow twitter account from our mobile phone with a sms. We just have to send sms to twitter. Imagine we create a twitter account with the user name of @username. Then we can send sms to 40404 as shown below.

follow @username

Then we start to get tweets which are tweeted in that account.

So after we create a twitter account then we can use Twitter API to post tweets from that account. Then all the clients who have follow that account as I mentioned before start to receiving tweets.

You can learn how to post tweets with twitter API from following link.

Twitter API

Before you start developing you have to get permission to use twitter api. You can get access to twitter api from following link.

Twitter Developer Console

This is not the best solution for your problem.But hope this help.
