Programs & Examples On #Test framework

Use this code on button click in activity and When return back to another activity just finish previous activity by setting flag in intent then put only one Activity in the Stack and destroy the previous one.

  Intent i=new Intent("this","YourClassName.Class");
  i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
  startActivity(i);

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

To clear the whole thing use the reset_session method in a controller.

reset_session

Here's the documentation on this method: http://api.rubyonrails.org/classes/ActionController/Base.html#M000668

Resets the session by clearing out all the objects stored within and initializing a new session object.

Good luck!

Indeed this problem is to be fixed under Preferences -> Java -> Installed JREs. If the desired JRE is apparent in the list - just select it, and that's it.

Otherwise it has to be installed on your computer first so you could add it with "Add" -> Standard VM -> Directory, in the pop-up browser window choose its path - something like "program files\Java\Jre#" -> "ok". And now you can select it from the list.

In Angular 8 we can do like this:

import { Injectable } from '@angular/core';
import { YourModel} from '../models/<yourModel>.model';
import { UserService } from './user.service';
import { Observable, of } from 'rxjs';
import { map, catchError } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})

export class GlobalDataService {

  private me: <YourModel>;

  private meObservable: Observable<User>;

  constructor(private yourModalService: <yourModalService>, private http: HttpClient) {

  }

  ngOnInit() {

  }


  getYourModel(): Observable<YourModel> {

    if (this.me) {
      return of(this.me);
    } else if (this.meObservable) {
      return this.meObservable;
    }
    else {
      this.meObservable = this.yourModalService.getCall<yourModel>() // Your http call
      .pipe(
        map(data => {
          this.me = data;
          return data;
        })
      );
      return this.meObservable;
    }
  }
}

You can call it like this:

this.globalDataService.getYourModel().subscribe(yourModel => {


});

The above code will cache the result of remote API at first call so that it can be used on further requests to that method.

I used the following lines of code to start zsh in the current directory in Win7.

Windows Registry Editor Version 5.00

note that i used %V instead of %L or %1 (since both didn't work for me)

not sure if my code is efficeient, anyone care to comment?

from math import isqrt

def isPrime(n):
    if n >= 2: # cheating the 2, is 2 even prime?

            if n % i == 0:
                return False
    return True

You need to handle the AppDomain.AssemblyResolve or AppDomain.ReflectionOnlyAssemblyResolve events (depending on which load you're doing) in case the referenced assembly is not in the GAC or on the CLR's probing path.

AppDomain.AssemblyResolve

AppDomain.ReflectionOnlyAssemblyResolve

Here is a generic function for it. Keep the RNG creation outside the high frequency code.

public static Random RNG = new Random();

public static T RandomEnum<T>()
{  
    Type type = typeof(T);
    Array values = Enum.GetValues(type);
    lock(RNG)
    {
        object value= values.GetValue(RNG.Next(values.Length));
        return (T)Convert.ChangeType(value, type);
    }
}

Usage example:

System.Windows.Forms.Keys randomKey = RandomEnum<System.Windows.Forms.Keys>();

I love jtbandes answer, but since it is pretty long, I will add my own compact answer:

==, ===, eql?, equal?
are 4 comparators, ie. 4 ways to compare 2 objects, in Ruby.
As, in Ruby, all comparators (and most operators) are actually method-calls, you can change, overwrite, and define the semantics of these comparing methods yourself. However, it is important to understand, when Ruby's internal language constructs use which comparator:

== (value comparison)
Ruby uses :== everywhere to compare the values of 2 objects, eg. Hash-values:

{a: 'z'}  ==  {a: 'Z'}    # => false
{a: 1}    ==  {a: 1.0}    # => true

=== (case comparison)
Ruby uses :=== in case/when constructs. The following code snippets are logically identical:

case foo
  when bar;  p 'do something'
end

if bar === foo
  p 'do something'
end

eql? (Hash-key comparison)
Ruby uses :eql? (in combination with the method hash) to compare Hash-keys. In most classes :eql? is identical with :==.
Knowledge about :eql? is only important, when you want to create your own special classes:

class Equ
  attr_accessor :val
  alias_method  :initialize, :val=
  def hash()           self.val % 2             end
  def eql?(other)      self.hash == other.hash  end
end

h = {Equ.new(3) => 3,  Equ.new(8) => 8,  Equ.new(15) => 15}    #3 entries, but 2 are :eql?
h.size            # => 2
h[Equ.new(27)]    # => 15

Note: The commonly used Ruby-class Set also relies on Hash-key-comparison.

equal? (object identity comparison)
Ruby uses :equal? to check if two objects are identical. This method (of class BasicObject) is not supposed to be overwritten.

obj = obj2 = 'a'
obj.equal? obj2       # => true
obj.equal? obj.dup    # => false

Here is a jQuery version based off of Holf's version and works with Chrome and Firefox whereas his version seems to only work with Chrome. It's a little strange to add something to the body to do this but if someone has a better option I'm all for it.

var exportFileName = "export-" + filename;
$('<a></a>', {
    "download": exportFileName,
    "href": "data:," + JSON.stringify(exportData, null,5),
    "id": "exportDataID"
}).appendTo("body")[0].click().remove();

Real solution for it case:

android:layout_weight="1" for TextView, and your button move to right!

There are a few ways that a file path can be represented. You should use the System.IO.Path class to get the separators for the OS, since it can vary between UNIX and Windows. Also, most (or all if I'm not mistaken) .NET libraries accept either a '\' or a '/' as a path separator, regardless of OS. For this reason, I'd use the Path class to split your paths. Try something like the following:

string originalPath = "\\server\\folderName1\\another\ name\\something\\another folder\\";
string[] filesArray = originalPath.Split(Path.AltDirectorySeparatorChar,
                              Path.DirectorySeparatorChar);

This should work regardless of the number of folders or the names.

Try this one. (LINK)

There is several escaping options with same result:

body { width: ~"calc(100% - 250px - 1.5em)"; }
body { width: calc(~"100% - 250px - 1.5em"); }
body { width: calc(100% ~"-" 250px ~"-" 1.5em); }

You can use XDocument.Parse(string) instead of Load(string).

you need to join the two tables:

for instance you want to copy the value of name from tableA into tableB where they have the same ID

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 
WHERE t2.name = 'Joe'

UPDATE 1

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 

UPDATE 2

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.name = t2.name
SET t1.value = t2.value

Ctrl+A , Ctrl+Shift+U

should do the trick!

Edit: Ctrl+U is the shortcut to be used to convert capital letters to lowercase (reverse scenario)

How about:

if (regexMatcher.find()) {
    resultString = regexMatcher.replaceAll(
            String.valueOf(3 * Integer.parseInt(regexMatcher.group(1))));
}

To get the first match, use #find(). After that, you can use #group(1) to refer to this first match, and replace all matches by the first maches value multiplied by 3.

And in case you want to replace each match with that match's value multiplied by 3:

    Pattern p = Pattern.compile("(\\d{1,2})");
    Matcher m = p.matcher("12 54 1 65");
    StringBuffer s = new StringBuffer();
    while (m.find())
        m.appendReplacement(s, String.valueOf(3 * Integer.parseInt(m.group(1))));
    System.out.println(s.toString());

You may want to look through Matcher's documentation, where this and a lot more stuff is covered in detail.

Firebug as Firefox (FF) extension is currently (as per 01/2017) the only way to debug direct javascript responses from AJAX calls. Unfortunately, it's development is discontinued. And since Firefox 50, the Firebug also cannot be installed anymore due to compatability issues :-( They kind of emulated FF developer tools UI to recall Firebug UI in some way.

Unfortunatelly, FF native developer tools are not able to debug javascript returned directly by AJAX calls. Same applies to Chrome devel. tools.

I must have disabled upgrades of FF due to this issue, since I badly need to debug JS from XHR calls on current project. So not good news here - let's hope the feature to debug direct JS responses will be incorporated into FF/Chrome developer tools soon.

You cannot use next() in this scenario, if you look at the documentation it says:
Next() Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling that matches the selector.

so if the second DIV was in the same TD then you could code:

// Won't work in your case
$(obj).next().filter('.class');

$(obj).parents('table').find('.class')

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

Use the sed delete command with a range address. For example:

sed 1,100d file.txt # Print file.txt omitting lines 1-100.

Alternatively, if you want to only print a known range, use the print command with the -n flag:

sed -n 201,300p file.txt # Print lines 201-300 from file.txt

This solution should work reliably on all Unix systems, regardless of the presence of GNU utilities.

I came here because currently the WordPress table block doesn't support the colspan parameter and i thought i will replace it using CSS. This was my solution, assuming that the columns are the same width:

table {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
table td {_x000D_
  width: 50%;_x000D_
  background: #dbdbdb;_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
table tr:nth-child(2n+1) {_x000D_
  position:relative;_x000D_
  display:block;_x000D_
  height:20px;_x000D_
  background:green;_x000D_
}_x000D_
_x000D_
table tr:nth-child(2n+1) td {_x000D_
  position:absolute;_x000D_
  left:0;_x000D_
  right:-100%;_x000D_
  width: auto;_x000D_
  top:0;_x000D_
  bottom:0;_x000D_
  background:red;_x000D_
  text-align:center;_x000D_
}

<table>_x000D_
    <tr>_x000D_
        <td>row</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td>cell</td>_x000D_
        <td>cell</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td>row</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td>cell</td>_x000D_
        <td>cell</td>_x000D_
    </tr>_x000D_
</table>

Just so it be noted: If the requirement to preserve the elements order is relaxed it is much more efficient to replace the element being removed with the last element.

There are many valid answers. Adding one more to the bunch. from sklearn.cross_validation import train_test_split

#gets a random 80% of the entire set
X_train = X.sample(frac=0.8, random_state=1)
#gets the left out portion of the dataset
X_test = X.loc[~df_model.index.isin(X_train.index)]

f = open(fname,'r')
lines = f.readlines()[1:]
f.close()

The official Jenkins documentation only mentions single line commands like the following:

// Declarative //

and (see)

pipeline {
    /* insert Declarative Pipeline here */
}

The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:

/* a standalone multiline comment
   spanning two lines */
println "hello" /* a multiline comment starting
                   at the end of a statement */
println 1 /* one */ + 2 /* two */

or

/**
 * such a nice comment
 */

use the String.Trim() function.

string foo = "   hello ";
string bar = foo.Trim();

Console.WriteLine(bar); // writes "hello"

You can use System.in to read from the standard input. It works just like entering it from a keyboard. The OS handles going from file to standard input.

class MyProg {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Printing the file passed in:");
        while(sc.hasNextLine()) System.out.println(sc.nextLine());
    }
}

You can to use Count Lines of Code (CLOC)

On Settings -> External Tools add a new tool

• Name: Count Lines of Code
• Group: Statistics
• Program: path/to/cloc
• Parameters: $ProjectFileDir$ or $FileParentDir$

Use git rm foo to stage the file for deletion. (This will also delete the file from the file system, if it hadn't been previously deleted. It can, of course, be restored from git, since it was previously checked in.)

To stage the file for deletion without deleting it from the file system, use git rm --cached foo

You can simply use the "Replace" function in SQL Server.

like this ::

select REPLACE('this is a test message','"','')

note: second parameter here is "double quotes" inside two single quotes and third parameter is simply a combination of two single quotes. The idea here is to replace the double quotes with a blank.

Very simple and easy to execute !

Yes, but unless you expect to have millions of rows, not using a string-based key because it's slower is usually "premature optimization." After all, strings are stored as big numbers while numeric keys are usually stored as smaller numbers.

One thing to watch out for, though, is if you have clustered indices on a any key and are doing large numbers of inserts that are non-sequential in the index. Every line written will cause the index to re-write. if you're doing batch inserts, this can really slow the process down.

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

The question may be getting old, but I've struggled with the same issue just now.

After deleting passwords with resetroot.bat, as instructed by Nedshed, you can choose another password by going to http://localhost/security/index.php

In your code j is Already json data and j['places'] is list not dict.

 r = requests.get('http://api.zippopotam.us/us/ma/belmont')
 j = r.json()

 print j['state']
 for each in j['places']:
    print each['latitude']

Try marginTop in place of margin-top, eg:

$("#ActionBox").css("marginTop", foo);

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

brainsandwich and underscore_d gave very good ideas. Since to fill is to change content, for_each(), the simplest among the STL algorithms, should also fill the bill:

std::vector<int> v(10);
std::for_each(v.begin(), v.end(), [i=0] (int& x) mutable {x = i++;});    

The generalized capture [i=o] imparts the lambda expression with an invariant and initializes it to a known state (in this case 0). the keyword mutable allows this state to be updated each time lambda is called.

It takes only a slight modification to get a sequence of squares:

std::vector<int> v(10);
std::for_each(v.begin(), v.end(), [i=0] (int& x) mutable {x = i*i; i++;});

To generate R-like seq is no more difficult, but note that in R, the numeric mode is actually double, so there really isn't a need to parametrize the type. Just use double.

Use sapply and is.na<-

> dat <- data.frame(a=c(1, Inf), b=c(Inf, 3), d=c("a","b"))
> is.na(dat) <- sapply(dat, is.infinite)
> dat
   a  b d
1  1 NA a
2 NA  3 b

Or you can use (giving credit to @mnel, whose edit this is),

> is.na(dat) <- do.call(cbind,lapply(dat, is.infinite))

which is significantly faster.

If at all possible, its always a good idea to create your XML using the XML classes rather than string manipulation - one of the benefits being that the classes will automatically escape characters as needed.

If you just want to log the list of elements, you can use the list toString() method which already concatenates all the list elements.

find . -size +10000k -exec ls -sd {} +

If your version of find won't accept the + notation (which acts rather like xargs does), then you might use (GNU find and xargs, so find probably supports + anyway):

find . -size +10000k -print0 | xargs -0 ls -sd

or you might replace the + with \; (and live with the relative inefficiency of this), or you might live with problems caused by spaces in names and use the portable:

find . -size +10000k -print | xargs ls -sd

The -d on the ls commands ensures that if a directory is ever found (unlikely, but...), then the directory information will be printed, not the files in the directory. And, if you're looking for files more than 1 MB (as a now-deleted comment suggested), you need to adjust the +10000k to 1000k or maybe +1024k, or +2048 (for 512-byte blocks, the default unit for -size). This will list the size and then the file name. You could avoid the need for -d by adding -type f to the find command, of course.

Try using fetchone:

cursor.execute("SELECT COUNT(*) from result where server_state='2' AND name LIKE '"+digest+"_"+charset+"_%'")
result=cursor.fetchone()

result will hold a tuple with one element, the value of COUNT(*). So to find the number of rows:

number_of_rows=result[0]

Or, if you'd rather do it in one fell swoop:

cursor.execute("SELECT COUNT(*) from result where server_state='2' AND name LIKE '"+digest+"_"+charset+"_%'")
(number_of_rows,)=cursor.fetchone()

PS. It's also good practice to use parametrized arguments whenever possible, because it can automatically quote arguments for you when needed, and protect against sql injection.

The correct syntax for parametrized arguments depends on your python/database adapter (e.g. mysqldb, psycopg2 or sqlite3). It would look something like

cursor.execute("SELECT COUNT(*) from result where server_state= %s AND name LIKE %s",[2,digest+"_"+charset+"_%"])
(number_of_rows,)=cursor.fetchone()

If your data is in wide format matplot is made for this and often forgotten about:

 dat <- matrix(runif(40,1,20),ncol=4) # make data
 matplot(dat, type = c("b"),pch=1,col = 1:4) #plot
 legend("topleft", legend = 1:4, col=1:4, pch=1) # optional legend

There is also the added bonus for those unfamiliar with things like ggplot that most of the plotting paramters such as pch etc. are the same using matplot() as plot().

EDIT: I experimented some, and discovered thing are a bit subtler than I thought. Here's what I now think is an accurate answer.

&s is not an lvalue so you cannot create a reference to it unless the type of the reference is reference to const. So for example, you cannot do

string * &r = &s;

but you can do

string * const &r = &s;

If you put a similar declaration in the function header, it will work.

void myfunc(string * const &a) { ... }

There is another issue, namely, temporaries. The rule is that you can get a reference to a temporary only if it is const. So in this case one might argue that &s is a temporary, and so must be declared const in the function prototype. From a practical point of view it makes no difference in this case. (It's either an rvalue or a temporary. Either way, the same rule applies.) However, strictly speaking, I think it is not a temporary but an rvalue. I wonder if there is a way to distinguish between the two. (Perhaps it is simply defined that all temporaries are rvalues, and all non-lvalues are temporaries. I'm not an expert on the standard.)

That being said, your problem is probably at a higher level. Why do you want a reference to the address of s? If you want a reference to a pointer to s, you need to define a pointer as in

string *p = &s;
myfunc(p);

If you want a reference to s or a pointer to s, do the straightforward thing.

Using 400 status codes for any other purpose than indicating that the request is malformed is just plain wrong.

If the request payload contains a byte-sequence that could not be parsed as application/json (if the server expects that dataformat), the appropriate status code is 415:

The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method.

If the request payload is syntactically correct but semantically incorrect, the non-standard 422 response code may be used, or the standard 403 status code:

The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated.

Just reading the file into an array, one line per element, is trivial:

open my $handle, '<', $path_to_file;
chomp(my @lines = <$handle>);
close $handle;

Now the lines of the file are in the array @lines.

If you want to make sure there is error handling for open and close, do something like this (in the snipped below, we open the file in UTF-8 mode, too):

my $handle;
unless (open $handle, "<:encoding(utf8)", $path_to_file) {
   print STDERR "Could not open file '$path_to_file': $!\n";
   # we return 'undefined', we could also 'die' or 'croak'
   return undef
}
chomp(my @lines = <$handle>);
unless (close $handle) {
   # what does it mean if close yields an error and you are just reading?
   print STDERR "Don't care error while closing '$path_to_file': $!\n";
} 

For %d part refer to this How does this program work? and for decimal places use %.2f

This is what solved my problem. ^M is a carriage return, and it can be easily avoided in a Perl script.

while(<INPUTFILE>)
{
     chomp;
     chop($_) if ($_ =~ m/\r$/);
}

The example below is based on your comments. It uses a List of keywords, which will be searched in a given String using word boundaries. It uses StringUtils from Apache Commons Lang to build the regular expression and print the matched groups.

String text = "I will come and meet you at the woods 123woods and all the woods";

List<String> tokens = new ArrayList<String>();
tokens.add("123woods");
tokens.add("woods");

String patternString = "\\b(" + StringUtils.join(tokens, "|") + ")\\b";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(text);

while (matcher.find()) {
    System.out.println(matcher.group(1));
}

If you are looking for more performance, you could have a look at StringSearch: high-performance pattern matching algorithms in Java.

Add this to your .pro file

I also had an issue with this problem simply copy and pasting DATETIME fields from SQL Management Studio to Excel for manipulation. Excel has the correct value of the DATETIME (even if the formatting is applied after the paste), but by default doesn't have a built in format to show the SQL DATETIME. Here's the fix:

Right click the cell, and choose Format Cells. Choose Custom. In the Type: input field enter

yyyy-mm-dd hh:mm:ss.000

Reference: http://office.microsoft.com/en-us/excel-help/create-a-custom-number-format-HP010342372.aspx

If you want to send your data inside the body, then you have to make a POST or PUT instead of GET.

For me, it looks like you're trying to send the query with uri parameters, which is not related to GET, you can also put these parameters on POST, PUT and so on.

The query is an optional part, separated by a question mark ("?"), that contains additional identification information that is not hierarchical in nature. The query string syntax is not generically defined, but it is commonly organized as a sequence of = pairs, with the pairs separated by a semicolon or an ampersand.

For example:

curl http://server:5050/a/c/getName?param0=foo&param1=bar

CSS3 offers a way to do it with the @font-face rule.

http://www.w3.org/TR/css3-webfonts/#the-font-face-rule

http://www.css3.info/preview/web-fonts-with-font-face/

Here is a number of different ways which will work in browsers that don't support the @font-face rule.

You get and format like this

for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
     set dow=%%i
     set month=%%j
     set day=%%k
     set year=%%l
)
set datestr=%month%_%day%_%year%
echo datestr is %datestr%

Note: Above only works on US locale. It assumes the output of echo %date% looks like this: Thu 02/13/21. If you have different Windows locale settings, you will need to modify the script based on your configuration.

Using tee with option -a (--append) allows you to append to multiple files at once and also to use sudo (very useful when appending to protected files). Besides that, it is interesting if you need to use other shells besides bash, as not all shells support the > and >> operators

echo "hello world" | sudo tee -a output.txt

This thread has good answers about tee

Here you go:

SELECT Field1, COUNT(Field1)
  FROM Table1 
 GROUP BY Field1
HAVING COUNT(Field1) > 1
ORDER BY Field1 desc

I'm a little out of touch with the details of how MySQL deals with nulls, but here's two things to try:

SELECT * FROM match WHERE id NOT IN 
    ( SELECT id FROM email WHERE id IS NOT NULL) ;

SELECT
    m.*
FROM
    match m
    LEFT OUTER JOIN email e ON
        m.id = e.id
        AND e.id IS NOT NULL
WHERE
    e.id IS NULL

The second query looks counter intuitive, but it does the join condition and then the where condition. This is the case where joins and where clauses are not equivalent.

For win7 chrome can be found at:

C:\Users\[UserName]\AppData\Local\Google\Chrome\Application\chrome.exe

For VS2017 click the little down arrow next to the run in debug/release mode button to find the "browse with..." option.

Whilst not a description of the differences, below are a couple of things to think about when choosing the correct method.

• GET requests can get cached by the browser which can be a problem (or benefit) when using ajax.
• GET requests expose parameters to users (POST does as well but they are less visible).
• POST can pass much more information to the server and can be of almost any length.

Just use padding to wrap it like this:

Column(
  children: <Widget>[
  Padding(
    padding: EdgeInsets.all(8.0),
    child: Text('Hello World!'),
  ),
  Padding(
    padding: EdgeInsets.all(8.0),
    child: Text('Hello World2!'),
  )
]);

You can also use Container(padding...) or SizeBox(height: x.x). The last one is the most common but it will depents of how you want to manage the space of your widgets, I like to use padding if the space is part of the widget indeed and use sizebox for lists for example.

There are windows installers for MySQLdb avaialable for both 32 and 64 bit, supporting Python from 2.6 to 3.4. Check here.

The And operator evaluates both sides, where AndAlso evaluates the right side if and only if the left side is true.

An example:

If mystring IsNot Nothing And mystring.Contains("Foo") Then
  ' bla bla
End If

The above throws an exception if mystring = Nothing

If mystring IsNot Nothing AndAlso mystring.Contains("Foo") Then
  ' bla bla
End If

This one does not throw an exception.

So if you come from the C# world, you should use AndAlso like you would use &&.

can you Try this and tell me what happens ?? :

JAVA :

ImageView imgFavorite = (ImageView) findViewById(R.id.favorite_icon);
imgFavorite.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(YourActivityName.this,
                "The favorite list would appear on clicking this icon",
                Toast.LENGTH_LONG).show();
    }
});

or you should add this :

imgFavorite.setClickable(true); 

KOTLIN :

imgFavorite.setOnClickListener { view ->
    Toast.makeText(this@YourActivityName, R.string.toast_favorite_list_would_appear, Toast.LENGTH_LONG).show()
}
// either you make your imageView clickable programmatically
imgFavorite.clickable = true

// or via xml on your layout file
<ImageView .... android:clickable="true" />

Use:

//REVENUE_YEAR[starts-with(.,'2552')]/../REGION/text() 

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

Here is complete article about streaming android camera video to a webpage.

Android Streaming Live Camera Video to Web Page

1. Used libstreaming on android app
2. On server side Wowza Media Engine is used to decode the video stream
3. Finally jWplayer is used to play the video on a webpage.

Assume I have a variable named file that contains a file. Then I could use file.write("hello\talex").

1. file.write("hello means I'm starting to write to this file.
2. \t means a tab
3. alex") is the rest I'm writing

You could also do this

#include <comdef.h>

BSTR bs = SysAllocString("Hello");
std::wstring myString = _bstr_t(bs, false); // will take over ownership, so no need to free

or std::string if you prefer

EDIT: if your original string contains multiple embedded \0 this approach will not work.

Use the DateTime.ToUniversalTime method.

I had many users controls but one refused to show in the Toolbox, even though I rebuilt the solution and it was checked in the Choose Items... dialog.

Solution:

1. From Solution Explorer I Right-Clicked the offending user control file and selected Exclude From Project
2. Rebuild the solution
3. Right-Click the user control and select Include in Project (assuming you have the Show All Files enabled in the Solution Explorer)

Note this also requires you have the AutoToolboxPopulate option enabled. As @DaveF answer suggests.

Alternate Solution: I'm not sure if this works, and I couldn't try it since I already resolved my issue, but if you unchecked the user control from the Choose Items... dialog, hit OK, then opened it back up and checked the user control. That might also work.

The answer of @PeterOlson may be worked back in the day but it looks like Object.create is changed. I would go for the copy-constructor way like @user166390 said in the comments.
The reason I necromanced this post is because I needed such implementation.

Nowadays we can use Object.assign (credits to @SayanPal solution) & ES6 syntax:

class Person {
  constructor(obj) {
    obj && Object.assign(this, obj);
  }

  getFullName() {
    return `${this.lastName} ${this.firstName}`;
  }
}

Usage:

const newPerson = new Person(person1)
newPerson.getFullName() // -> Freeman Gordon

ES5 answer below

function Person(obj) {
    for(var prop in obj){
        // for safety you can use the hasOwnProperty function
        this[prop] = obj[prop];
    }
}

Usage:

var newPerson = new Person(person1);
console.log(newPerson.getFullName()); // -> Freeman Gordon

Using a shorter version, 1.5 liner:

function Person(){
    if(arguments[0]) for(var prop in arguments[0]) this[prop] = arguments[0][prop];
}

The easiest way to find the best fit in R is to code the model as:

lm.1 <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + ...)

After using step down AIC regression

lm.s <- step(lm.1)

Just how you've done it. assertTrue(boolean) also has an overload assertTrue(String, boolean) where the String is the message in case of failure; you can use that if you want to print that such-and-such wasn't greater than so-and-so.

You could also add hamcrest-all as a dependency to use matchers. See https://code.google.com/p/hamcrest/wiki/Tutorial:

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.*;

assertThat("timestamp",
           Long.parseLong(previousTokenValues[1]),
           greaterThan(Long.parseLong(currentTokenValues[1])));

That gives an error like:

java.lang.AssertionError: timestamp
Expected: a value greater than <456L>
     but: <123L> was less than <456L>

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

None of the other current answers will actually "merge" the files, as if you were using the merge command. (At best they'll require you to manually pick diffs.) If you actually want to take advantage of merging using the information from a common ancestor, you can follow a procedure based on one found in the "Advanced Merging" section of the git Reference Manual.

For this protocol, I'm assuming you're wanting to merge the file 'path/to/file.txt' from origin/master into HEAD - modify as appropriate. (You don't have to be in the top directory of your repository, but it helps.)

# Find the merge base SHA1 (the common ancestor) for the two commits:
git merge-base HEAD origin/master

# Get the contents of the files at each stage
git show <merge-base SHA1>:path/to/file.txt > ./file.common.txt
git show HEAD:path/to/file.txt > ./file.ours.txt
git show origin/master:path/to/file.txt > ./file.theirs.txt

# You can pre-edit any of the files (e.g. run a formatter on it), if you want.

# Merge the files
git merge-file -p ./file.ours.txt ./file.common.txt ./file.theirs.txt > ./file.merged.txt

# Resolve merge conflicts in ./file.merged.txt
# Copy the merged version to the destination
# Clean up the intermediate files

git merge-file should use all of your default merge settings for formatting and the like.

Also note that if your "ours" is the working copy version and you don't want to be overly cautious, you can operate directly on the file:

git merge-base HEAD origin/master
git show <merge-base SHA1>:path/to/file.txt > ./file.common.txt
git show origin/master:path/to/file.txt > ./file.theirs.txt
git merge-file path/to/file.txt ./file.common.txt ./file.theirs.txt

<html>
    <head>
        <script>
        function callme(field) {
            alert("field:" + field.value);
        }
        </script>
    </head>
    <body>
        <form name="f1">
            <input type="text" onkeyup="callme(this);" name="text1">
        </form>
    </body>
</html>

It looks like you can use the onkeyup to get the new value of the HTML input control. Hope it helps.

Get the Method Names:

var getMethodNames = function (obj) {
    return (Object.getOwnPropertyNames(obj).filter(function (key) {
        return obj[key] && (typeof obj[key] === "function");
    }));
};

Or, Get the Methods:

var getMethods     = function (obj) {
    return (Object.getOwnPropertyNames(obj).filter(function (key) {
        return obj[key] && (typeof obj[key] === "function");
    })).map(function (key) {
        return obj[key];
    });
};

SELECT last_value, increment_by from "other_schema".id_seq;

for adding a seq to a column where the schema is not public try this.

nextval('"other_schema".id_seq'::regclass)

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

which means that cacerts keystore isn't password protected

That's a false assumption. If you read more carefully, you'll find that the listing was provided without verifying the integrity of the keystore because you didn't provide the password. The listing doesn't require a password, but your keystore definitely has a password, as indicated by:

In order to verify its integrity, you must provide your keystore password.

Java's default cacerts password is "changeit", unless you're on a Mac, where it's "changeme" up to a certain point. Apparently as of Mountain Lion (based on comments and another answer here), the password for Mac is now also "changeit", probably because Oracle is now handling distribution for the Mac JVM as well.

this is an .htaccess file that forward almost all to index.php

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_URI} !-l
RewriteCond %{REQUEST_FILENAME} !\.(ico|css|png|jpg|gif|js)$ [NC]
# otherwise forward it to index.php
RewriteRule . index.php

then is up to you parse $_SERVER["REQUEST_URI"] and route to picture.php or whatever

We can download a specified branch by using following magical command:

git clone -b < branch name > <remote_repo url> 

I assume this is a one-off data scrubbing exercise. Once done, ensure you add database constraints to prevent bad data in the future e.g.

ALTER TABLE Customer ADD
   CONSTRAINT customer_names__whitespace
      CHECK (
             Names NOT LIKE ' %'
             AND Names NOT LIKE '% '
             AND Names NOT LIKE '%  %'
            );

Also consider disallowing other characters (tab, carriage return, line feed, etc) that may cause problems.

It may also be a good time to split those Names into family_name, first_name, etc :)

Check if have not set a open_basedir in php.ini or .htaccess of domain what you use. That will jail you in directory of your domain and php will get only access to execute inside this directory.

I suppose you have imported math.h with #include <math.h>

So the only other reason I can see is a missing linking information. You must link your code with the -lm option.

If you're simply trying to compile one file with gcc, just add -lm to your command line, otherwise, give some informations about your building process.

Convert it Like

string s = System.DBNull.value.ToString();

Just a minor addition: The speed difference between memcpy() and std::copy() can vary quite a bit depending on if optimizations are enabled or disabled. With g++ 6.2.0 and without optimizations memcpy() clearly wins:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy            17 ns         17 ns   40867738
bm_stdcopy           62 ns         62 ns   11176219
bm_stdcopy_n         72 ns         72 ns    9481749

When optimizations are enabled (-O3), everything looks pretty much the same again:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy             3 ns          3 ns  274527617
bm_stdcopy            3 ns          3 ns  272663990
bm_stdcopy_n          3 ns          3 ns  274732792

The bigger the array the less noticeable the effect gets, but even at N=1000 memcpy() is about twice as fast when optimizations aren't enabled.

Source code (requires Google Benchmark):

#include <string.h>
#include <algorithm>
#include <vector>
#include <benchmark/benchmark.h>

constexpr int N = 10;

void bm_memcpy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    memcpy(r.data(), a.data(), N * sizeof(int));
  }
}

void bm_stdcopy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy(a.begin(), a.end(), r.begin());
  }
}

  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy_n(a.begin(), N, r.begin());

Summary : Use an external script (batch file) that a) stops the server and b) Unlocks the .jar file before running maven-clean.

Steps:

1. Bind the maven-antrun-plugin:run goal to the pre-clean phase of mvn clean. See how to do this here

2. See how to use the antrun plugin to run an external batch file in Windows here : sblundy's answer to "Starting external process". Let's call this file unlock_handles.bat

3. Use the Sysinternals handle utility download link in the pre_clean.bat to a) stop the Tomcat server and b) unlock the .jar file. handle -c and handle -p would be useful here.

Whew! That's a bit of work, but it will reliably automate the process for you so that you do need to do it manually yourself each time!

OK, here's a rough, proof-of-concept version of unlock_handles.bat for you to try out:

REM "Use handle.exe to figure out the process id and handle ids, parse the output, then close the handle (again using handle.exe)"

cd "C:\Users\Nikolay_Tkachev\workspace\HHSystem\UI\target"
"c:/Program Files/Process Explorer/handle.exe" -p java.exe "C:\Users\Nikolay_Tkachev\workspace\HHSystem\UI\target" > handles.txt

@echo "O====== Going to unlock all the below file handles! =======O"
FOR /F "tokens=1-26 delims=: " %a in (handles.txt) DO @echo %h
FOR /F "tokens=1-26 delims=: " %a in (handles.txt) DO handle -p %c -c %f -y

Of course, you have to change the path to Sysinternals' handle.exe before giving this a try.

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

}

is not called every time it is called only when app is in forground

there is one override method this method is called every time , no matter what app is in foreground or in background or killed but this method is available with this firebase api version

this is the version u have to import from gradle

compile 'com.google.firebase:firebase-messaging:10.2.1'

this is the method

@Override
public void handleIntent(Intent intent) {
    super.handleIntent(intent);

    // you can get ur data here 
    //intent.getExtras().get("your_data_key") 


}

with previous firebase api this method was not there so in that case fire base handle itself when app is in background .... now u have this method what ever u want to do ... u can do it here in this method .....

if you are using previous version than default activity will start in that case u can get data same way

if(getIntent().getExtras() != null && getIntent().getExtras().get("your_data_key") != null) {
String strNotificaiton = getIntent().getExtras().get("your_data_key").toString();

// do what ever u want .... }

generally this is the structure from server we get in notification

{
    "notification": {
        "body": "Cool offers. Get them before expiring!",
        "title": "Flat 80% discount",
        "icon": "appicon",
        "click_action": "activity name" //optional if required.....
    },
    "data": {
        "product_id": 11,
        "product_details": "details.....",
        "other_info": "......."
    }
}

it's up to u how u want to give that data key or u want give notification anything u can give ....... what ever u will give here with same key u will get that data .........

there are few cases if u r not sending click action in that case when u will click on notification default activity will open , but if u want to open your specific activity when app is in background u can call your activity from this on handleIntent method because this is called every time

You can easily reach them by using the Run window and entering:

shell:startup

and

shell:common startup

The output is what you would hope for:

$text="abc1234567890";

// truncate to 4 chars

echo substr(str_pad($text,4),0,4);

This avoids the problem of truncating a 4 char string to 10 chars .. (i.e. source is smaller than the required)

As long as you know the directory where your C++ libraries could be found at run time, this should be simple. I can clearly see that this is the case in your code. Your myDll.dll would be present inside myLibFolder directory inside temporary folder of the current user.

string str = Path.GetTempPath() + "..\\myLibFolder\\myDLL.dll"; 

Now you can continue using the DllImport statement using a const string as shown below:

[DllImport("myDLL.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int DLLFunction(int Number1, int Number2);

Just at run time before you call the DLLFunction function (present in C++ library) add this line of code in C# code:

string assemblyProbeDirectory = Path.GetTempPath() + "..\\myLibFolder\\myDLL.dll"; 
Directory.SetCurrentDirectory(assemblyProbeDirectory);

This simply instructs the CLR to look for the unmanaged C++ libraries at the directory path which you obtained at run time of your program. Directory.SetCurrentDirectory call sets the application's current working directory to the specified directory. If your myDLL.dll is present at path represented by assemblyProbeDirectory path then it will get loaded and the desired function will get called through p/invoke.

Five options:

• Use the free jsonutils web tool without installing anything.

• If you have Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class.

• Use the free jsonclassgenerator.exe

• The web tool app.quicktype.io does not require installing anything.

• The web tool json2csharp also does not require installing anything.

Pros and Cons:

• jsonclassgenerator converts to PascalCase but the others do not.

• app.quicktype.io has some logic to recognize dictionaries and handle JSON properties whose names are invalid c# identifiers.

When you have related tables you often have one-to-many or many-to-many relationships. So when you join to TableB each record in TableA many have multiple records in TableB. This is normal and expected.

Now at times you only need certain columns and those are all the same for all the records, then you would need to do some sort of group by or distinct to remove the duplicates. Let's look at an example:

TableA
Id Field1
1  test
2  another test

TableB
ID Field2 field3
1  Test1  something
1  test1  More something
2  Test2  Anything

So when you join them and select all the files you get:

select * 
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1        b.id   b.field2  b.field3
1    test            1      Test1     something
1    test            1      Test1     More something
2    another test 2  2      Test2     Anything

These are not duplicates because the values of Field3 are different even though there are repeated values in the earlier fields. Now when you only select certain columns the same number of records are being joined together but since the columns with the different information is not being displayed they look like duplicates.

select a.Id, a.Field1,  b.field2
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1       b.field2  
1    test           Test1     
1    test           Test1 
2    another test   Test2

This appears to be duplicates but it is not because of the multiple records in TableB.

You normally fix this by using aggregates and group by, by using distinct or by filtering in the where clause to remove duplicates. How you solve this depends on exactly what your business rule is and how your database is designed and what kind of data is in there.

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

CREATE OR REPLACE PROCEDURE insert_into (

InputStream raw = context.getAssets().open("filename.ext");

Reader is = new BufferedReader(new InputStreamReader(raw, "UTF8"));

It makes it clear that the method accepts null values, and that if you override the method, you should also accept null values.

It also serves as a hint for code analyzers like FindBugs. For example, if such a method dereferences its argument without checking for null first, FindBugs will emit a warning.

On your MainForm make a function to set the textbox the checks the InvokeRequired

public void AppendTextBox(string value)
{
    if (InvokeRequired)
    {
        this.Invoke(new Action<string>(AppendTextBox), new object[] {value});
        return;
    }
    ActiveForm.Text += value;
}

although in your static method you can't just call.

WindowsFormsApplication1.Form1.AppendTextBox("hi. ");

you have to have a static reference to the Form1 somewhere, but this isn't really recommended or necessary, can you just make your SampleFunction not static if so then you can just call

AppendTextBox("hi. ");

It will append on a differnt thread and get marshalled to the UI using the Invoke call if required.

Full Sample

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        new Thread(SampleFunction).Start();
    }

    public void AppendTextBox(string value)
    {
        if (InvokeRequired)
        {
            this.Invoke(new Action<string>(AppendTextBox), new object[] {value});
            return;
        }
        textBox1.Text += value;
    }

    void SampleFunction()
    {
        // Gets executed on a seperate thread and 
        // doesn't block the UI while sleeping
        for(int i = 0; i<5; i++)
        {
            AppendTextBox("hi.  ");
            Thread.Sleep(1000);
        }
    }
}

Easily done in Bootstrap 3 like so:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

Use this code:

 HttpContext.Current.Server.MapPath("~")

Detailed Reference:

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

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

An example:

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

C:\Inetpub\wwwroot

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

D:\WebApps\shop

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

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

then:

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

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

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

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

Footnotes

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

Also make sure the aspx page has AutoEventWireup="true" and not AutoEventWireup="false"

Since I have to store various types of content in my blob field/column, I am suppose to update my code like this:

echo "data: $mime" $result['$data']";

where: mime can be an image of any kind, text, word document, text document, PDF document, etc... content datatype is blob in database.

I used Brendan Bullen's answer as a starting point for a similar issue I had which was to retrive the value of a specific field in a JSON string. However, like I commented on his answer, it is not entirely accurate. If your left boundary isn't just a space like in the original question, then the discrepancy increases.

Corrected solution:

SUBSTRING(
    sentence,
    LOCATE(' ', sentence) + 1,
    LOCATE(' ', sentence, (LOCATE(' ', sentence) + 1)) - LOCATE(' ', sentence) - 1
)

The two differences are the +1 in the SUBSTRING index parameter and the -1 in the length parameter.

For a more general solution to "find the first occurence of a string between two provided boundaries":

SUBSTRING(
    haystack,
    LOCATE('<leftBoundary>', haystack) + CHAR_LENGTH('<leftBoundary>'),
    LOCATE(
        '<rightBoundary>',
        haystack,
        LOCATE('<leftBoundary>', haystack) + CHAR_LENGTH('<leftBoundary>')
    )
    - (LOCATE('<leftBoundary>', haystack) + CHAR_LENGTH('<leftBoundary>'))
)

You can attach event to element when dynamically created using jQuery(html, attributes).

As of jQuery 1.8, any jQuery instance method (a method of jQuery.fn) can be used as a property of the object passed to the second parameter:

function handleDynamicElementEvent(event) {_x000D_
  console.log(event.type, this.value)_x000D_
}_x000D_
// create and attach event to dynamic element_x000D_
jQuery("<select>", {_x000D_
    html: $.map(Array(3), function(_, index) {_x000D_
      return new Option(index, index)_x000D_
    }),_x000D_
    on: {_x000D_
      change: handleDynamicElementEvent_x000D_
    }_x000D_
  })_x000D_
  .appendTo("body");

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">_x000D_
</script>

Here goes:

char str[] = "This is the end";
char input[100];

printf("%s\n", str);
printf("%c\n", *str);

scanf("%99s", input);

I use the FALLBACK option in the HTML5 cache manifest to check if my html5 app is online or offline by:

FALLBACK:
/online.txt /offline.txt

In the html page i use javascript tot read the contents of the online/offline txt file:

<script>$.get( "urlto/online.txt", function( data ) {
$( ".result" ).html( data );
alert( data );
});</script>

When offline the script will read the contents of the offline.txt. Based on the text in the files you can detect if the webpage is online of offline.

I added a \n in the middle of my string and it looked okay.

Its called Longest Common Substring problem. Here I present a simple, easy to understand but inefficient solution. It will take a long time to produce correct output for large strings, as the complexity of this algorithm is O(N^2).

def longestSubstringFinder(string1, string2):
    answer = ""
    len1, len2 = len(string1), len(string2)
    for i in range(len1):
        match = ""
        for j in range(len2):
            if (i + j < len1 and string1[i + j] == string2[j]):
                match += string2[j]
            else:
                if (len(match) > len(answer)): answer = match
                match = ""
    return answer

print longestSubstringFinder("apple pie available", "apple pies")
print longestSubstringFinder("apples", "appleses")
print longestSubstringFinder("bapples", "cappleses")

Output

apple pie
apples
apples

Run it through an XSLT identity transform with <xsl:output indent="no"> and <xsl:strip-space elements="*"/>

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="no" />
    <xsl:strip-space elements="*"/>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

It will remove any of the non-significant whitespace and produce the expected output that you posted.

Mongoose 4.4 added a method called insertMany

Shortcut for validating an array of documents and inserting them into MongoDB if they're all valid. This function is faster than .create() because it only sends one operation to the server, rather than one for each document.

Quoting vkarpov15 from issue #723:

The tradeoffs are that insertMany() doesn't trigger pre-save hooks, but it should have better performance because it only makes 1 round-trip to the database rather than 1 for each document.

The method's signature is identical to create:

Model.insertMany([ ... ], (err, docs) => {
  ...
})

Or, with promises:

Model.insertMany([ ... ]).then((docs) => {
  ...
}).catch((err) => {
  ...
})

I had the same problem. My solution was to make all vectors numeric.

MOV can do same thing as LEA [label], but MOV instruction contain the effective address inside the instruction itself as an immediate constant (calculated in advance by the assembler). LEA uses PC-relative to calculate the effective address during the execution of the instruction.

Rails 5 comes with an or method. (link to documentation)

This method accepts an ActiveRecord::Relation object. eg:

User.where(first_name: 'James').or(User.where(last_name: 'Scott'))

Try this one

$('<div></div>').appendTo('body')
  .html('<div><h6>Yes or No?</h6></div>')
  .dialog({
      modal: true, title: 'message', zIndex: 10000, autoOpen: true,
      width: 'auto', resizable: false,
      buttons: {
          Yes: function () {
              doFunctionForYes();
              $(this).dialog("close");
          },
          No: function () {
              doFunctionForNo();
              $(this).dialog("close");
          }
      },
      close: function (event, ui) {
          $(this).remove();
      }
});

Fiddle

One option is to use a numbers/tally table to drive an iterative process via a pseudo-set based query.

The general idea of char replacement can be demonstrated with a simple character map table approach:

create table charMap (srcChar char(1), replaceChar char(1))
insert charMap values ('a', 'z')
insert charMap values ('b', 'y')


create table testChar(srcChar char(1))
insert testChar values ('1')
insert testChar values ('a')
insert testChar values ('2')
insert testChar values ('b')

select 
coalesce(charMap.replaceChar, testChar.srcChar) as charData
from testChar left join charMap on testChar.srcChar = charMap.srcChar

Then you can bring in the tally table approach to do the lookup on each character position in the string.

create table tally (i int)
declare @i int
set @i = 1
while @i <= 256 begin
    insert tally values (@i)
    set @i = @i + 1
end

create table testData (testString char(10))
insert testData values ('123a456')
insert testData values ('123ab456')
insert testData values ('123b456')

select
    i,
    SUBSTRING(testString, i, 1) as srcChar,
    coalesce(charMap.replaceChar, SUBSTRING(testString, i, 1)) as charData
from testData cross join tally
    left join charMap on SUBSTRING(testString, i, 1) = charMap.srcChar
where i <= LEN(testString)

I use the combo of these two

    Private Sub sendData(ByVal zpl As String)
    Dim ns As System.Net.Sockets.NetworkStream = Nothing
    Dim socket As System.Net.Sockets.Socket = Nothing
    Dim printerIP As Net.IPEndPoint = Nothing
    Dim toSend As Byte()

    Try
        If printerIP Is Nothing Then
            'set the IP address
            printerIP = New Net.IPEndPoint(IPAddress.Parse(IP_ADDRESS), 9100)
        End If

        'Create a TCP socket
        socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
        'Connect to the printer based on the IP address
        socket.Connect(printerIP)
        'create a new network stream based on the socket connection
        ns = New NetworkStream(socket)

        'convert the zpl command to a byte array
        toSend = System.Text.Encoding.ASCII.GetBytes(zpl)

        'send the zpl byte array over the networkstream to the connected printer
        ns.Write(toSend, 0, toSend.Length)

    Catch ex As Exception
        MessageBox.Show(ex.Message, "Cable Printer", MessageBoxButtons.OKCancel, MessageBoxIcon.Error)
    Finally
        'close the networkstream and then the socket
        If Not ns Is Nothing Then
            ns.Close()
        End If

        If Not socket Is Nothing Then
            socket.Close()
        End If
    End Try
End Sub

Link function only gets called once, so it would not directly do what you are expecting. You need to use angular $watch to watch a model variable.

This watch needs to be setup in the link function.

If you use isolated scope for directive then the scope would be

scope :{typeId:'@' }

In your link function then you add a watch like

link: function(scope, element, attrs) {
    scope.$watch("typeId",function(newValue,oldValue) {
        //This gets called when data changes.
    });
 }

If you are not using isolated scope use watch on some_prop

Useful Python XML parsers:

1. Minidom - functional but limited
2. ElementTree - decent performance, more functionality
3. lxml - high-performance in most cases, high functionality including real xpath support

Any of those is better than trying to update the XML file as strings of text.

What that means to you:

Open your file with an XML parser of your choice, find the node you're interested in, replace the value, serialize the file back out.

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.

We can use set methods for this:

c1 = [1, 6, 7, 10, 13, 28, 32, 41, 58, 63]
c2 = [[13, 17, 18, 21, 32], [7, 11, 13, 14, 28], [1, 5, 6, 8, 15, 16]]

   result = [] 
   for li in c2:
       res = set(li) & set(c1)
       result.append(list(res))

   print result

Try wrapping your entire select in brackets, then running a count(*) on that

select count(*)
from
(
   select m.id
   from Monitor as m 
    inner join Monitor_Request as mr 
       on mr.Company_ID=m.Company_id   group by m.Company_id
    having COUNT(m.Monitor_id)>=5
) myNewTable

In C# when debugging threads for example, you can see each thread's ID.

This will be the Ids of the managed threads. ManagedThreadId is a member of Thread so you can get the Id from any Thread object. This will get you the current ManagedThreadID:

Thread.CurrentThread.ManagedThreadId

To get an OS thread by its OS thread ID (not ManagedThreadID), you can try a bit of linq.

int unmanagedId = 2345;
ProcessThread myThread = (from ProcessThread entry in Process.GetCurrentProcess().Threads
   where entry.Id == unmanagedId 
   select entry).First();

It seems there is no way to enumerate the managed threads and no relation between ProcessThread and Thread, so getting a managed thread by its Id is a tough one.

For more details on Managed vs Unmanaged threading, see this MSDN article.

From the Java Tutorial:

A stream is a sequence of data.

A program uses an input stream to read data from a source, one item at a time:

A program uses an output stream to write data to a destination, one item at time:

The data source and data destination pictured above can be anything that holds, generates, or consumes data. Obviously this includes disk files, but a source or destination can also be another program, a peripheral device, a network socket, or an array.

Sample code from oracle tutorial:

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class CopyBytes {
    public static void main(String[] args) throws IOException {

        FileInputStream in = null;
        FileOutputStream out = null;

        try {
            in = new FileInputStream("xanadu.txt");
            out = new FileOutputStream("outagain.txt");
            int c;

            while ((c = in.read()) != -1) {
                out.write(c);
            }
        } finally {
            if (in != null) {
                in.close();
            }
            if (out != null) {
                out.close();
            }
        }
    }
}

This program uses byte streams to copy xanadu.txt file to outagain.txt , by writing one byte at a time

Have a look at this SE question to know more details about advanced Character streams, which are wrappers on top of Byte Streams :

byte stream and character stream

Your comment suggests you're trying to call this from a programming language. If that's the case, can your program fork a child process that calls sleep then does the work?

What about having your program calculate the number of seconds until the desired runtime, and have it call shell_exec("sleep ${secondsToWait) ; myCommandToRun");

public class checkBoxSel {

    public static void main(String[] args) {

         WebDriver driver = new FirefoxDriver();
         EventFiringWebDriver dr = null ;


         dr = new EventFiringWebDriver(driver);
         dr.get("http://www.google.co.in/");

         dr.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

         dr.findElement(By.linkText("Gmail")).click() ;

         Select sel = new Select(driver.findElement(By.tagName("select")));
         sel.selectByValue("fil");

    }

}

I am using GOOGLE LOGIN PAGE to test the seletion option. The above example was to find and select language "Filipino" from the drop down list. I am sure this will solve the problem.

There is a way to create "const" variables in Java, but only for specific classes. Just define a class with final properties and subclass it. Then use the base class where you would want to use "const". Likewise, if you need to use "const" methods, add them to the base class. The compiler will not allow you to modify what it thinks is the final methods of the base class, but it will read and call methods on the subclass.

Another option is to use an array, e.g. void method(SomeClass[] v) { v[0] = ...; } but 1) the array must be initialized before method invoked, 2) still one cannot implement e.g. swap method in this way... This way is used in JDK, e.g. in java.util.concurrent.atomic.AtomicMarkableReference.get(boolean[]).

Building off of user1827356 's answer, you can do the assignment in one pass using df.merge:

df.merge(df.textcol.apply(lambda s: pd.Series({'feature1':s+1, 'feature2':s-1})), 
    left_index=True, right_index=True)

    textcol  feature1  feature2
0  0.772692  1.772692 -0.227308
1  0.857210  1.857210 -0.142790
2  0.065639  1.065639 -0.934361
3  0.819160  1.819160 -0.180840
4  0.088212  1.088212 -0.911788

EDIT: Please be aware of the huge memory consumption and low speed: https://ys-l.github.io/posts/2015/08/28/how-not-to-use-pandas-apply/ !

Try this:

private byte[] Hex2Bin(string hex) 
{
 if ((hex == null) || (hex.Length < 1)) {
  return new byte[0];
 }
 int num = hex.Length / 2;
 byte[] buffer = new byte[num];
 num *= 2;
 for (int i = 0; i < num; i++) {
  int num3 = int.Parse(hex.Substring(i, 2), NumberStyles.HexNumber);
  buffer[i / 2] = (byte) num3;
  i++;
 }
 return buffer;
}

private string Bin2Hex(byte[] binary) 
{
 StringBuilder builder = new StringBuilder();
 foreach(byte num in binary) {
  if (num > 15) {
   builder.AppendFormat("{0:X}", num);
  } else {
   builder.AppendFormat("0{0:X}", num); /////// ?? 15 ???? 0
  }
 }
 return builder.ToString();
}

Did you try df.groupby('id').head(2)

Ouput generated:

>>> df.groupby('id').head(2)
       id  value
id             
1  0   1      1
   1   1      2 
2  3   2      1
   4   2      2
3  7   3      1
4  8   4      1

(Keep in mind that you might need to order/sort before, depending on your data)

EDIT: As mentioned by the questioner, use df.groupby('id').head(2).reset_index(drop=True) to remove the multindex and flatten the results.

>>> df.groupby('id').head(2).reset_index(drop=True)
    id  value
0   1      1
1   1      2
2   2      1
3   2      2
4   3      1
5   4      1

0xE0434352 is the exception code for all .NET exceptions so that won't tell you much. How did you got this exception code? The event log?

Your best bet is to use a debugger to get more information. If the Visual Studio debugger won't help you, then you might need to check out WinDbg with SOS. See here and here for an introduction. Let it break on the exception, and see if you can get more information on the why.

If you suspect it is an issue when loading assemblies you might want to check out the Fusion Log.

It's much better practise to avoid using sys.exit() and instead raise/handle exceptions to allow the program to finish cleanly. If you want to turn off traceback, simply use:

sys.trackbacklimit=0

You can set this at the top of your script to squash all traceback output, but I prefer to use it more sparingly, for example "known errors" where I want the output to be clean, e.g. in the file foo.py:

import sys
from subprocess import *

try:
  check_call([ 'uptime', '--help' ])
except CalledProcessError:
  sys.tracebacklimit=0
  print "Process failed"
  raise

print "This message should never follow an error."

If CalledProcessError is caught, the output will look like this:

[me@test01 dev]$ ./foo.py
usage: uptime [-V]
    -V    display version
Process failed
subprocess.CalledProcessError: Command '['uptime', '--help']' returned non-zero exit status 1

If any other error occurs, we still get the full traceback output.

This is code that I have effectively used before, passing "/" as the strPath parameter.

public static Cookie eraseCookie(String strCookieName, String strPath) {
    Cookie cookie = new Cookie(strCookieName, "");
    cookie.setMaxAge(0);
    cookie.setPath(strPath);

    return cookie;
}

The cleanest way, as far as I know:

1. add your JSP variable to an HTML element's data-* attribute
2. then read this value via Javascript when required

My opinion regarding the current solutions on this SO page: reading "directly" JSP values using java scriplet inside actual javascript code is probably the most disgusting thing you could do. Makes me wanna puke. haha. Seriously, try to not do it.

The HTML part without JSP:

<body data-customvalueone="1st Interpreted Jsp Value" data-customvaluetwo="another Interpreted Jsp Value">
    Here is your regular page main content
</body>

The HTML part when using JSP:

<body data-customvalueone="${beanName.attrName}" data-customvaluetwo="${beanName.scndAttrName}">
    Here is your regular page main content
</body>

The javascript part (using jQuery for simplicity):

<script type="text/JavaScript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.js"></script>
<script type="text/javascript">
    jQuery(function(){
        var valuePassedFromJSP = $("body").attr("data-customvalueone");
        var anotherValuePassedFromJSP = $("body").attr("data-customvaluetwo");

        alert(valuePassedFromJSP + " and " + anotherValuePassedFromJSP + " are the values passed from your JSP page");
});
</script>

And here is the jsFiddle to see this in action http://jsfiddle.net/6wEYw/2/

Resources:

• HTML 5 data-* attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes
• Include javascript into html file Include JavaScript file in HTML won't work as <script .... />
• CSS selectors (also usable when selecting via jQuery) https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Getting_started/Selectors
• Get an HTML element attribute via jQuery http://api.jquery.com/attr/

The first answer is essentially correct, but if you want the very simplest way to accomplish the desired result, here's a stand-alone code example demonstrating how to do it with a semaphore (which is also how dispatch groups work behind the scenes, JFYI):

#include <dispatch/dispatch.h>
#include <stdio.h>

main()
{
        dispatch_queue_t myQ = dispatch_queue_create("my.conQ", DISPATCH_QUEUE_CONCURRENT);
        dispatch_semaphore_t mySem = dispatch_semaphore_create(0);

        dispatch_async(myQ, ^{ printf("Hi I'm block one!\n"); sleep(2); dispatch_semaphore_signal(mySem);});
        dispatch_async(myQ, ^{ printf("Hi I'm block two!\n"); sleep(4); dispatch_semaphore_signal(mySem);});
        dispatch_async(myQ, ^{ dispatch_semaphore_wait(mySem, DISPATCH_TIME_FOREVER); printf("Hi, I'm the final block!\n"); });
        dispatch_main();
}

I don't think that best practice will be passing a variable like req.YOUR_VAR. You might want to consider req.YOUR_APP_NAME.YOUR_VAR or req.mw_params.YOUR_VAR.

It will help you avoid overwriting other attributes.

res.locals is what you're looking for, the object is scoped to the request.

An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any). Otherwise, this property is identical to app.locals.

This property is useful for exposing request-level information such as the request path name, authenticated user, user settings, and so on.

Starting Webcam Video with different browsers

For Opera 12

window.navigator.getUserMedia(param, function(stream) {
                            video.src =window.URL.createObjectURL(stream);
                        }, videoError );

For Firefox Nightly 18.0

window.navigator.mozGetUserMedia(param, function(stream) {
                            video.mozSrcObject = stream;
                        }, videoError );

For Chrome 22

window.navigator.webkitGetUserMedia(param, function(stream) {
                            video.src =window.webkitURL.createObjectURL(stream);
                        },  videoError );

Stopping Webcam Video with different browsers

For Opera 12

video.pause();
video.src=null;

For Firefox Nightly 18.0

video.pause();
video.mozSrcObject=null;

For Chrome 22

video.pause();
video.src="";

With this the Webcam light go down everytime...

if your invoke shell script like

/home/mike/runme.sh

$0 is full name

 /home/mike/runme.sh

basename $0 will get the base file name

 runme.sh

and you need to put this basic name into a variable like

filename=$(basename $0)

and add your additional text

echo "You are running $filename"

so your scripts like

/home/mike/runme.sh
#!/bin/bash 
filename=$(basename $0)
echo "You are running $filename"

Do the following:

Dim dataTable1 As New DataTable
                dataTable1.Columns.Add("FECHA")
                dataTable1.Columns.Add("TT")
                dataTable1.Columns.Add("DESCRIPCION")
                dataTable1.Columns.Add("No. DOC")
                dataTable1.Columns.Add("DEBE")
                dataTable1.Columns.Add("HABER")
                dataTable1.Columns.Add("SALDO")

For Each line As String In System.IO.File.ReadAllLines(objetos.url)
                    dataTable1.Rows.Add(line.Split(","))
                Next

Swift 3 : Array() can be useful to do this .

Get Key :

let index = 5 // Int Value
Array(myDict)[index].key

Get Value :

Array(myDict)[index].value

^y will copy the character above the cursor.

You need to retrieve and disect the information into what you need.

while($row = mysql_fetch_array($result)) {
 echo "img src='",$row['filename'],"' width='175' height='200' />";
}

Or did you want to just see if a column only has NULL values (and, thus, is probably unused)?

Further clarification of the question might help.

EDIT: Ok.. here's some really rough code to get you going...

SET NOCOUNT ON
DECLARE @TableName Varchar(100)
SET @TableName='YourTableName'
CREATE TABLE #NullColumns (ColumnName Varchar(100), OnlyNulls BIT)
INSERT INTO #NullColumns (ColumnName, OnlyNulls) SELECT c.name, 0 FROM syscolumns c INNER JOIN sysobjects o ON c.id = o.id AND o.name = @TableName AND o.xtype = 'U'
DECLARE @DynamicSQL AS Nvarchar(2000)
DECLARE @ColumnName Varchar(100)
DECLARE @RC INT
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    WHILE @@ROWCOUNT > 0
    BEGIN
        SET @RC=0
        SET @DynamicSQL = 'SELECT TOP 1 1 As HasNonNulls FROM ' + @TableName + ' (nolock) WHERE ''' + @ColumnName + ''' IS NOT NULL'
        EXEC sp_executesql @DynamicSQL
        set @RC=@@rowcount
        IF @RC=1
        BEGIN
            SET @DynamicSQL = 'UPDATE #NullColumns SET OnlyNulls=1 WHERE ColumnName=''' + @ColumnName + ''''
            EXEC sp_executesql @DynamicSQL
        END
        ELSE
        BEGIN
            SET @DynamicSQL = 'DELETE FROM #NullColumns WHERE ColumnName=''' + @ColumnName+ ''''
            EXEC sp_executesql @DynamicSQL
        END
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    END

SELECT * FROM #NullColumns

DROP TABLE #NullColumns
SET NOCOUNT OFF

Yes, there are easier ways, but I have a meeting to go to right now. Good luck!

Found a Fix:

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.

.success { background-color: #cffccc; overflow: scroll; min-width: 100%; }

You can try scroll or auto.

Self-executing anonymous function. It's executed as soon as it is created.

One short and dummy example where this is useful is:

function prepareList(el){
  var list = (function(){
    var l = []; 
    for(var i = 0; i < 9; i++){
     l.push(i);
    }
    return l;
  })();

  return function (el){
    for(var i = 0, l = list.length; i < l; i++){
      if(list[i] == el) return list[i];
    }
    return null;
  }; 
} 

var search = prepareList();
search(2);
search(3);

So instead of creating a list each time, you create it only once (less overhead).

Left, Right and Below tabs were removed from Bootstrap 3, but you can add custom CSS to achieve this..

.tabs-below > .nav-tabs,
.tabs-right > .nav-tabs,

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

Late but wanted to add a new one with more keyframes ... here is an example on CodePen since there was an issue with the built-in code snippets:

Here is a jsfiddle so you can see an example of this working.

<div class='circle'></div>

I don't see why you are grouping here.

Try this:

var maxValue = table.Max(x => x.Status)
var result = table.First(x => x.Status == maxValue);

An alternate approach that would iterate table only once would be this:

var result = table.OrderByDescending(x => x.Status).First();

This is helpful if table is an IEnumerable<T> that is not present in memory or that is calculated on the fly.

Here's a clean solution:

private byte[] downloadUrl(URL toDownload) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

    try {
        byte[] chunk = new byte[4096];
        int bytesRead;
        InputStream stream = toDownload.openStream();

        while ((bytesRead = stream.read(chunk)) > 0) {
            outputStream.write(chunk, 0, bytesRead);
        }

    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }

    return outputStream.toByteArray();
}

try with this code...

 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
         <property name="ignoreUnresolvablePlaceholders" value="true"/>
             <property name="locations">
              <list>                        
                    <value>/social.properties</value>               
              </list>
         </property>         
        </bean>

Two solutions for this:

1. PHP function nl2br():

   e.g.,

   echo nl2br("This\r\nis\n\ra\nstring\r");
   
   // will output
   This<br />
   is<br />
   a<br />
   string<br />
   

2. Wrap the input in <pre></pre> tags.

   See: W3C Wiki - HTML/Elements/pre

There is a simple rule of thumb to tell you when to use == or is.

• == is for value equality. Use it when you would like to know if two objects have the same value.
• is is for reference equality. Use it when you would like to know if two references refer to the same object.

In general, when you are comparing something to a simple type, you are usually checking for value equality, so you should use ==. For example, the intention of your example is probably to check whether x has a value equal to 2 (==), not whether x is literally referring to the same object as 2.

Something else to note: because of the way the CPython reference implementation works, you'll get unexpected and inconsistent results if you mistakenly use is to compare for reference equality on integers:

>>> a = 500
>>> b = 500
>>> a == b
True
>>> a is b
False

That's pretty much what we expected: a and b have the same value, but are distinct entities. But what about this?

>>> c = 200
>>> d = 200
>>> c == d
True
>>> c is d
True

This is inconsistent with the earlier result. What's going on here? It turns out the reference implementation of Python caches integer objects in the range -5..256 as singleton instances for performance reasons. Here's an example demonstrating this:

>>> for i in range(250, 260): a = i; print "%i: %s" % (i, a is int(str(i)));
... 
250: True
251: True
252: True
253: True
254: True
255: True
256: True
257: False
258: False
259: False

This is another obvious reason not to use is: the behavior is left up to implementations when you're erroneously using it for value equality.

You can avoid blocking execution by writing the plot to an array, then displaying the array in a different thread. Here is an example of generating and displaying plots simultaneously using pf.screen from pyformulas 0.2.8:

import pyformulas as pf
import matplotlib.pyplot as plt
import numpy as np
import time

fig = plt.figure()

canvas = np.zeros((480,640))
screen = pf.screen(canvas, 'Sinusoid')

Most distributions have installed the GUI app file-roller which unpacks tar, zip, rpm and many more.

file-roller --extract-here package.rpm

This will extract the contents in the current directory.

You must pip install pyserial first.

There are so many ways to do this, here is some more:

string.Join(Environment.NewLine, dictionary.Select(a => $"{a.Key}: {a.Value}"))

dictionary.Select(a => $"{a.Key}: {a.Value}{Environment.NewLine}")).Aggregate((a,b)=>a+b)

new String(dictionary.SelectMany(a => $"{a.Key}: {a.Value} {Environment.NewLine}").ToArray())

Additionally, you can then use one of these and encapsulate it in an extension method:

public static class DictionaryExtensions
{
    public static string ToReadable<T,V>(this Dictionary<T, V> d){
        return string.Join(Environment.NewLine, d.Select(a => $"{a.Key}: {a.Value}"));
    }   
}

And use it like this: yourDictionary.ToReadable().

use return before calling the function, while you click the submit button, two events(form posting as you used submit button and function call for onclick) will happen, to prevent form posting you have to return false, you have did it, also you have to specify the return i.e, to expect a value from the function,

this is a code:

input type="submit" name="continue" value="submit" onClick="**return** checkform();"

When programming the NODEMCU card with the Arduino IDE, you need to customize it and you must have selected the correct card.

Open Arduino IDE and go to files and click on the preference in the Arduino IDE.

Add the following link to the Additional Manager URLS section: "http://arduino.esp8266.com/stable/package_esp8266com_index.json" and press the OK button.

Then click Tools> Board Manager. Type "ESP8266" in the text box to search and install the ESP8266 software for Arduino IDE.

You will be successful when you try to program again by selecting the NodeMCU card after these operations. I hope I could help.

There's a whole page of the Django documentation devoted to this, well indexed from the contents page.

As that page states, you need to do:

my_obj.categories.add(fragmentCategory.objects.get(id=1))

or

my_obj.categories.create(name='val1')

Either use casting as others have already said, or multiply one of the int variables by 1.0:

double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));

Unexpected '='

This can be caused by having invalid characters in a variable name. Variables names must follow these rules:

Variable names follow the same rules as other labels in PHP. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thus: '[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*'

final keyword in the method input parameter is not needed. Java creates a copy of the reference to the object, so putting final on it doesn't make the object final but just the reference, which doesn't make sense

you could try wrapping the items in a dom element like here. with this you dont have to know a lot of css just having a good structure will solve the problem.

To specify current directory, use a "." for your destination directory:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

UPDATE March 2016

By Android Support Library 23.2.1 of a support library version. So all WRAP_CONTENT should work correctly.

Please update version of a library in gradle file.

compile 'com.android.support:recyclerview-v7:23.2.1'

This allows a RecyclerView to size itself based on the size of its contents. This means that previously unavailable scenarios, such as using WRAP_CONTENT for a dimension of the RecyclerView, are now possible.

you’ll be required to call setAutoMeasureEnabled(true)

Fixed bugs related to various measure-spec methods in update

In object-oriented programming, polymorphism refers to a programming language's ability to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes.

All of the existing answers use the deprecated MD5Init(), MD5Update(), and MD5Final().

Instead, use EVP_DigestInit_ex(), EVP_DigestUpdate(), and EVP_DigestFinal_ex(), e.g.

// example.c
//
// gcc example.c -lssl -lcrypto -o example

#include <openssl/evp.h>
#include <stdio.h>
#include <string.h>

void bytes2md5(const char *data, int len, char *md5buf) {
  // Based on https://www.openssl.org/docs/manmaster/man3/EVP_DigestUpdate.html
  EVP_MD_CTX *mdctx = EVP_MD_CTX_new();
  const EVP_MD *md = EVP_md5();
  unsigned char md_value[EVP_MAX_MD_SIZE];
  unsigned int md_len, i;
  EVP_DigestInit_ex(mdctx, md, NULL);
  EVP_DigestUpdate(mdctx, data, len);
  EVP_DigestFinal_ex(mdctx, md_value, &md_len);
  EVP_MD_CTX_free(mdctx);
  for (i = 0; i < md_len; i++) {
    snprintf(&(md5buf[i * 2]), 16 * 2, "%02x", md_value[i]);
  }
}

int main(void) {
  const char *hello = "hello";
  char md5[33]; // 32 characters + null terminator
  bytes2md5(hello, strlen(hello), md5);
  printf("%s\n", md5);
}

To anyone else who tried most of the solutions and still having problems.

My solution is different from the others, which is located at the bottom of this post, but before you try it make sure you have exhausted the following lists. To be sure, I have tried all of them but to no avail.

1. Recompile and redeploy from scratch, don't update the existing app. SO Answer

2. Grant IIS_IUSRS full access to the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files"

   Keep in mind the framework version you are using. If your app is using impersonation, use that identity instead of IIS_IUSRS

3. Delete all contents of the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files".

   Keep in mind the framework version you are using

4. Change the identity of the AppPool that your app is using, from ApplicatonPoolIdentity to NetworkService.

   IIS > Application Pools > Select current app pool > Advance Settings > Identity.

   SO Answer (please restore to default if it doesn't work)

5. Verify IIS Version and AppPool .NET version compatibility with your app. Highly applicable to first time deployments. SO Answer

6. Verify impersonation configuration if applicable. SO Answer

My Solution:

I found out that certain anti-virus softwares are actively blocking compilations of DLLs within the directory "Temporary ASP.NET Files", mine was McAfee, the IT people failed to notify me of the installation.

As per advice by both McAfee experts and Microsoft, you need to exclude the directory "Temporary ASP.NET Files" in the real time scanning.

Sources:

• McAfee Support Forum
• Microsoft Support
• Asp.Net Forum

Don't disable the Anti-Virus because it is only doing its job. Don't manually copy missing DLL files in the directory \Temporary ASP.NET Files{project name} because thats duct taping.

You can use regular expression like this:

import re

print re.search('[a-zA-Z]+',string)

The problem is that POST method is forbidden for Nginx server's static files requests. Here is the workaround:

# Pass 405 as 200 for requested address:

server {
listen       80;
server_name  localhost;

location / {
    root   html;
    index  index.html index.htm;
}

error_page  404     /404.html;
error_page  403     /403.html;

error_page  405     =200 $uri;
}

If using proxy:

# If Nginx is like proxy for Apache:

error_page 405 =200 @405; 

location @405 { 
    root /htdocs; 
    proxy_pass http://localhost:8080; 
}

If using FastCGI:

location ~\.php(.*) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include /etc/nginx/fastcgi_params;
}

Browsers usually use GET, so you can use online tools like ApiTester to test your requests.

css href link is incorrect. Use relative path instead:

<link href="../css/loginstyle.css" rel="stylesheet" type="text/css">

I had the same problem as Daniel, setting the commit address and unsetting the credentials helper also worked for me.

git config --global user.email '<git-commit-address>'
git config --global --unset credential.helper

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

If you are looking for a way to import all your images from the image

// Import all images in image folder
function importAll(r) {
    let images = {};
    r.keys().map((item, index) => { images[item.replace('./', '')] = r(item); });
    return images;
}

const images = importAll(require.context('../images', false, /\.(gif|jpe?g|svg)$/));

Then:

<img src={images['image-01.jpg']}/>

You can find the original thread here: Dynamically import images from a directory using webpack

In order to write into a file in Python, we need to open it in write w, append a or exclusive creation x mode.

We need to be careful with the w mode, as it will overwrite into the file if it already exists. Due to this, all the previous data are erased.

Writing a string or sequence of bytes (for binary files) is done using the write() method. This method returns the number of characters written to the file.

with open('Failed.py','w',encoding = 'utf-8') as f:
   f.write("Write what you want to write in\n")
   f.write("this file\n\n")

This program will create a new file named Failed.py in the current directory if it does not exist. If it does exist, it is overwritten.

We must include the newline characters ourselves to distinguish the different lines.

The best solution is to add to your apache .htaccess file the following line after RewriteEngine On

RewriteRule ^sitemap\.xml$ sitemap.php [L]

and then simply having a file sitemap.php in your root folder that would be normally accessible via http://www.yoursite.com/sitemap.xml, the default URL where all search engines will firstly search.

The file sitemap.php shall start with

<?php
//Saturday, 11 January 2020 @kevin

header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
            http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">

<url>
  <loc>https://www.yoursite.com/</loc>
  <lastmod>2020-01-08T13:06:14+00:00</lastmod>
  <priority>1.00</priority>
</url>


</urlset>

it works :)

the safest way is to put the ! for the regex negation within the [[ ]] like this:

if [[ ! ${STR} =~ YOUR_REGEX ]]; then

otherwise it might fail on certain systems.

You had already identified the accepts parameter as the one you wanted and keyur is right in showing you the correct way to set it, but if you set DataType to "json" then it will automatically set the default value of accepts to the value you want as per the jQuery reference. So all you need is:

jQuery.ajax({
    url: _this.attr('href'),
    dataType: "json"
});

Yes you can...

WITH SET1 AS (SELECT SYSDATE FROM DUAL), -- SET1 initialised
     SET2 AS (SELECT * FROM SET1)        -- SET1 accessed
SELECT * FROM SET2;                      -- SET2 projected

Follow the order in which it should be initialized in Common Table Expressions

do while in an exit control loop. while is an entry control loop.

You can check the total number of arguments which are passed in command line with "$#" Say for Example my shell script name is hello.sh

sh hello.sh hello-world
# I am passing hello-world as argument in command line which will b considered as 1 argument 
if [ $# -eq 1 ] 
then
    echo $1
else
    echo "invalid argument please pass only one argument "
fi

Output will be hello-world

I needed to solve this problem too when Django was displaying Decimal type values in a text field. E.g. when '1' was the value. It would show '1.00000000'. If '1.23' was the value, it would show '1.23000000' (In the case of a 'decimal_places' setting of 8)

Using parseFloat was not an option for me since it is possible it does not return the exact same value. toFixed was not an option since I did not want to round anything, so I created a function:

function removeTrailingZeros(value) {
    value = value.toString();

    # if not containing a dot, we do not need to do anything
    if (value.indexOf('.') === -1) {
        return value;
    }

    # as long as the last character is a 0 or a dot, remove it
    while((value.slice(-1) === '0' || value.slice(-1) === '.') && value.indexOf('.') !== -1) {
        value = value.substr(0, value.length - 1);
    }
    return value;
}

The app can't be run natively, but it could be run on an emulator. You can use ManyMo to embed them in a website and make users add your app to their home screen. This link should be useful for making the app more realistic. Users could then only press the share button and add the app to their home screen. All data will be deleted when the "app" is closed in their iOS devices so you should use the Internet/cloud for storage. It can't access camera or multi touch, but it may be useful.

You can access the delegate like this:

MainClass *appDelegate = (MainClass *)[[UIApplication sharedApplication] delegate];

Replace MainClass with the name of your application class.

Then, provided you have a property for the other view controller, you can call something like:

[appDelegate.viewController someMethod];

A nice code for the push_back and emplace_back is shown here.

http://en.cppreference.com/w/cpp/container/vector/emplace_back

You can see the move operation on push_back and not on emplace_back.

You need to use a date formatting function for example to_char http://www.postgresql.org/docs/current/static/functions-formatting.html
