Check target framework in the projects.

In my case "You must add a reference to assembly" actually meant, that caller and reference projects didn't have the same target framework. The caller project had .Net 4.5 , but referenced library had target 4.6.1.

I am sure, that MS compiler can be smarter and log more meaningful error message. I've added a suggestion to https://github.com/dotnet/roslyn/issues/14756

You can use dbeaver to do this. It allows you to export the ER diagram as png/svg etc.

DBeaver - https://dbeaver.io/

Double click on a schema (eg, Schemas->public->Tables) and open the "ER Diagram" tab (next to "Properties" tab)

Assuming you're using Python's logging module, you can pass the string formatting arguments as arguments to the .debug() method rather than doing the formatting yourself:

log.debug("some debug info: %s", some_info)

which avoids doing the formatting unless the logger actually logs something.

I ran into this trying to integrate React Native into an existing swift project using cocoapods. The FB docs (at time of writing) did not specify that npm install react-native wouldn't work without first having a package.json file. Per the RN docs set your entry point: (index.js) as index.ios.js

You are almost always better off using an options hash.

def ldap_get(base_dn, filter, options = {})
  options[:scope] ||= LDAP::LDAP_SCOPE_SUBTREE
  ...
end

ldap_get(base_dn, filter, :attrs => X)

Use Mach-OView for viewing all the Symbols in dylib

That depends on what you mean. If you just want to get rid of them, do this:
(Update: Apparently you want to keep digits as well, use the second lines in that case)

String alphaOnly = input.replaceAll("[^a-zA-Z]+","");
String alphaAndDigits = input.replaceAll("[^a-zA-Z0-9]+","");

or the equivalent:

String alphaOnly = input.replaceAll("[^\\p{Alpha}]+","");
String alphaAndDigits = input.replaceAll("[^\\p{Alpha}\\p{Digit}]+","");

(All of these can be significantly improved by precompiling the regex pattern and storing it in a constant)

Or, with Guava:

private static final CharMatcher ALNUM =
  CharMatcher.inRange('a', 'z').or(CharMatcher.inRange('A', 'Z'))
  .or(CharMatcher.inRange('0', '9')).precomputed();
// ...
String alphaAndDigits = ALNUM.retainFrom(input);

But if you want to turn accented characters into something sensible that's still ascii, look at these questions:

• Converting Java String to ASCII
• Java change áéouú to aeouu
• n ? n ñ ? n ? ? ? ¨ ? ? ? ? ? --> n or Remove diacritical marks from unicode chars

The solution below was the best format I found.

log_format postdata escape=json '$remote_addr - $remote_user [$time_local] '
                       '"$request" $status $bytes_sent '
                       '"$http_referer" "$http_user_agent" "$request_body"';
server {
        listen 80;

        server_name api.some.com;

        location / {
         access_log  /var/log/nginx/postdata.log  postdata;
         proxy_pass      http://127.0.0.1:8080;
        }

}

For this input

curl -d '{"key1":"value1", "key2":"value2"}' -H "Content-Type: application/json" -X POST http://api.deprod.com/postEndpoint

Generate that great result

201.23.89.149 -  [22/Aug/2019:15:58:40 +0000] "POST /postEndpoint HTTP/1.1" 200 265 "" "curl/7.64.0" "{\"key1\":\"value1\", \"key2\":\"value2\"}"

In SQLite this is simpler. I think there are similar implementations for MySQL, MSSql and Orable

CREATE TABLE Beatles (id integer, name string );
INSERT INTO Beatles VALUES (1, "Paul");
INSERT INTO Beatles VALUES (2, "John");
INSERT INTO Beatles VALUES (3, "Ringo");
INSERT INTO Beatles VALUES (4, "George");
SELECT GROUP_CONCAT(name, ',') FROM Beatles;

Another point to add.

Overloading More than one method with Same name. Same or different return type. Different no of parameters or Different type of parameters. In Same Class or Derived class.

int Add(int num1, int num2) int Add(int num1, int num2, int num3) double Add(int num1, int num2) double Add(double num1, double num2)

Can be possible in same class or derived class. Generally prefers in same class. E.g. Console.WriteLine() has 19 overloaded methods.

Can overload class constructors, methods.

Can consider as Compile Time (static / Early Binding) polymorphism.

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

Overriding cannot be possible in same class. Can Override class methods, properties, indexers, events.

Has some limitations like The overridden base method must be virtual, abstract, or override. You cannot use the new, static, or virtual modifiers to modify an override method.

InnoDB supports RENAME TABLE statement to move table from one database to another. To use it programmatically and rename database with large number of tables, I wrote a couple of procedures to get the job done. You can check it out here - SQL script @Gist

To use it simply call the renameDatabase procedure.

CALL renameDatabase('old_name', 'new_name');

Tested on MariaDB and should work ideally on all RDBMS using InnoDB transactional engine.

This works in Mavericks.

It basically means that the application wants to perform some "naming operations" (e.g. JNDI or LDAP lookups), and it didn't have sufficient information available to be able to create a connection to the directory server. As the docs for the exception state,

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

And if you dutifully have a look at the javadocs for InitialContext, they describe quite well how the initial context is constructed, and what your options are for supplying the address/credentials/etc.

If you have a go at creating the context and get stuck somewhere else, please post back explaining what you've done so far and where you're running aground.

numpy.random.seed(0)
numpy.random.randint(10, size=5)

This produces the following output: array([5, 0, 3, 3, 7]) Again,if we run the same code we will get the same result.

Now if we change the seed value 0 to 1 or others:

numpy.random.seed(1)
numpy.random.randint(10, size=5)

This produces the following output: array([5 8 9 5 0]) but now the output not the same like above.

In a nutshell, the syntax for Bower version numbers (and NPM's) is called SemVer, which is short for 'Semantic Versioning'. You can find documentation for the detailed syntax of SemVer as used in Bower and NPM on the API for the semver parser within Node/npm. You can learn more about the underlying spec (which does not mention ~ or other syntax details) at semver.org.

There's a super-handy visual semver calculator you can play with, making all of this much easier to grok and test.

SemVer isn't just a syntax! It has some pretty interesting things to say about the right ways to publish API's, which will help to understand what the syntax means. Crucially:

Once you identify your public API, you communicate changes to it with specific increments to your version number. Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes not affecting the API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version.

So, your specific question about ~ relates to that Major.Minor.Patch schema. (As does the related caret operator ^.) You can use ~ to narrow the range of versions you're willing to accept to either:

• subsequent patch-level changes to the same minor version ("bug fixes not affecting the API"), or:
• subsequent minor-level changes to the same major version ("backwards compatible API additions/changes")

For example: to indicate you'll take any subsequent patch-level changes on the 1.2.x tree, starting with 1.2.0, but less than 1.3.0, you could use:

"angular": "~1.2"
  or:
"angular": "~1.2.0"

This also gets you the same results as using the .x syntax:

"angular": "1.2.x"

But, you can use the tilde/~ syntax to be even more specific: if you're only willing to accept patch-level changes starting with 1.2.4, but still less than 1.3.0, you'd use:

"angular": "~1.2.4"

Moving left, towards the major version, if you use...

"angular": "~1"

... it's the same as...

"angular": "1.x"
  or:
"angular": "^1.0.0"

...and matches any minor- or patch-level changes above 1.0.0, and less than 2.0:

Note that last variation above: it's called a 'caret range'. The caret looks an awful lot like a >, so you'd be excused for thinking it means "any version greater than 1.0.0". (I've certainly slipped on that.) Nope!

Caret ranges are basically used to say that you care only about the left-most significant digit - usually the major version - and that you'll permit any minor- or patch-level changes that don't affect that left-most digit. Yet, unlike a tilde range that specifies a major version, caret ranges let you specify a precise minor/patch starting point. So, while ^1.0.0 === ~1, a caret range such as ^1.2.3 lets you say you'll take any changes >=1.2.3 && <2.0.0. You couldn't do that with a tilde range.

That all seems confusing at first, when you look at it up-close. But zoom out for a sec, and think about it this way: the caret simply lets you say that you're most concerned about whatever significant digit is left-most. The tilde lets you say you're most concerned about whichever digit is right-most. The rest is detail.

It's the expressive power of the tilde and the caret that explains why people use them much more than the simpler .x syntax: they simply let you do more. That's why you'll see the tilde used often even where .x would serve. As an example, see npm itself: its own package.json file includes lots of dependencies in ~2.4.0 format, rather than the 2.4.x format it could use. By sticking to ~, the syntax is consistent all the way down a list of 70+ versioned dependencies, regardless of which beginning patch number is acceptable.

Anyway, there's still more to SemVer, but I won't try to detail it all here. Check it out on the node semver package's readme. And be sure to use the semantic versioning calculator while you're practicing and trying to get your head around how SemVer works.

RE: Non-Consecutive Version Numbers: OP's final question seems to be about specifying non-consecutive version numbers/ranges (if I have edited it fairly). Yes, you can do that, using the common double-pipe "or" operator: ||. Like so:

"angular": "1.2 <= 1.2.9 || >2.0.0"

You can write a for loop for this... %)

for x in *
do
        if [ "$x" != "exclude_criteria" ]
        then
                rm -f $x;
        fi
done;

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):

VARCHAR(65535) However, note that the limit is lower if you use a multi-byte character set:

VARCHAR(21844) CHARACTER SET utf8

You need to give the user table an alias the second time you join to it

e.g.

SELECT article . * , section.title, category.title, user.name, u2.name 
FROM article 
INNER JOIN section ON article.section_id = section.id 
INNER JOIN category ON article.category_id = category.id 
INNER JOIN user ON article.author_id = user.id 
LEFT JOIN user u2 ON article.modified_by = u2.id 
WHERE article.id = '1'

Use the builtin type function to get the type, then you can use the __module__ property to find out where it was defined:

>>> import numpy as np
a = np.array([1, 2, 3])
>>> type(a)
<type 'numpy.ndarray'>
>>> type(a).__module__
'numpy'
>>> type(a).__module__ == np.__name__
True

I think it is so it can keep consistency with the available options used when settings multiple css styles in one function call through the use of an object, for example...

$(".element").css( { marginLeft : "200px", marginRight : "200px" } );

as you can see the property are not specified as strings. JQuery also supports using string if you still wanted to use the dash, or for properties that perhaps cannot be set without the dash, so the following still works...

$(".element").css( { "margin-left" : "200px", "margin-right" : "200px" } );

without the quotes here, the javascript would not parse correctly as property names cannot have a dash in them.

EDIT: It would appear that JQuery is not actually making the distinction itsleft, instead it is just passing the property specified for the DOM to care about, most likely with style[propertyName];

Here's a C implementation based on Agoston's Computer Graphics and Geometric Modeling: Implementation and Algorithms p. 304, with H ? [0, 360] and S,V ? [0, 1].

#include <math.h>

typedef struct {
    double r;       // ? [0, 1]
    double g;       // ? [0, 1]
    double b;       // ? [0, 1]
} rgb;

typedef struct {
    double h;       // ? [0, 360]
    double s;       // ? [0, 1]
    double v;       // ? [0, 1]
} hsv;

rgb hsv2rgb(hsv HSV)
{
    rgb RGB;
    double H = HSV.h, S = HSV.s, V = HSV.v,
            P, Q, T,
            fract;

    (H == 360.)?(H = 0.):(H /= 60.);
    fract = H - floor(H);

    P = V*(1. - S);
    Q = V*(1. - S*fract);
    T = V*(1. - S*(1. - fract));

    if      (0. <= H && H < 1.)
        RGB = (rgb){.r = V, .g = T, .b = P};
    else if (1. <= H && H < 2.)
        RGB = (rgb){.r = Q, .g = V, .b = P};
    else if (2. <= H && H < 3.)
        RGB = (rgb){.r = P, .g = V, .b = T};
    else if (3. <= H && H < 4.)
        RGB = (rgb){.r = P, .g = Q, .b = V};
    else if (4. <= H && H < 5.)
        RGB = (rgb){.r = T, .g = P, .b = V};
    else if (5. <= H && H < 6.)
        RGB = (rgb){.r = V, .g = P, .b = Q};
    else
        RGB = (rgb){.r = 0., .g = 0., .b = 0.};

    return RGB;
}

In a pure Javascript way, you can submit the form after preventing default.

This is because HTMLFormElement.submit() never calls the onSubmit(). So we're relying on that specification oddity to submit the form as if it doesn't have a custom onsubmit handler here.

var submitHandler = (event) => {
  event.preventDefault()
  console.log('You should only see this once')
  document.getElementById('formId').submit()
}

See this fiddle for a synchronous request.

Waiting for an async request to finish up is just as easy:

var submitHandler = (event) => {
  event.preventDefault()
  console.log('before')
  setTimeout(function() {
    console.log('done')
    document.getElementById('formId').submit()
  }, 1400);
  console.log('after')
}

You can check out my fiddle for an example of an asynchronous request.

And if you are down with promises:

var submitHandler = (event) => {
  event.preventDefault()
  console.log('Before')
    new Promise((res, rej) => {
      setTimeout(function() {
        console.log('done')
        res()
      }, 1400);
    }).then(() => {
      document.getElementById('bob').submit()
    })
  console.log('After')
}

And here's that request.

A very important place where it is REQUIRED to use the key => value pair in foreach loop is to be mentioned. Suppose you would want to add a new/sub-element to an existing item (in another key) in the $features array. You should do the following:

foreach($features as $key => $feature) {
    $features[$key]['new_key'] = 'new value';  
} 

Instead of this:

foreach($features as $feature) {
    $feature['new_key'] = 'new value';  
} 

The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer.

While in the second (which doesn't work for this purpose) you are assigning the sub-value in the array to a temporary variable $feature which is unset after each loop iteration.

I had the same problem - i wanted to pass a parameter to another page by clicking a hyperlink and get the value to go to the next page (without using GET because the parameter is stored in the URL).

to those who don't understand why you would want to do this the answer is you dont want the user to see sensitive information or you dont want someone editing the GET.

well after scouring the internet it seemed it wasnt possible to make a normal hyperlink using the POST method.

And then i had a eureka moment!!!! why not just use CSS to make the submit button look like a normal hyperlink??? ...and put the value i want to pass in a hidden field

i tried it and it works. you can see an exaple here http://paulyouthed.com/test/css-button-that-looks-like-hyperlink.php

the basic code for the form is:

    <form enctype="multipart/form-data" action="page-to-pass-to.php" method="post">
                        <input type="hidden" name="post-variable-name" value="value-you-want-pass"/>
                        <input type="submit" name="whatever" value="text-to-display" id="hyperlink-style-button"/>
                </form>

the basic css is:

    #hyperlink-style-button{
      background:none;
      border:0;
      color:#666;
      text-decoration:underline;
    }

    #hyperlink-style-button:hover{
      background:none;
      border:0;
      color:#666;
      text-decoration:none;
      cursor:pointer;
      cursor:hand;
    }

One alternate way if file contains strings without spaces with 1string each line:

fileItemString=$(cat  filename |tr "\n" " ")

fileItemArray=($fileItemString)

Check:

Print whole Array:

${fileItemArray[*]}

Length=${#fileItemArray[@]}

you have to initialize it "by hand" :

char* c = new char[length];
for(int i = 0;i<length;i++)
    c[i]='\0';

 $('input[type="radio"]').change(function(){
      if($("input[name='group']:checked")){
      $(div).show();
    }
  });

Solution to the problem

as mentioned by Uberfuzzy [ real cause of problem ]

If you look at the PHP constant [PATH_SEPARATOR][1], you will see it being ":" for you.

If you break apart your string ".:/usr/share/pear:/usr/share/php" using that character, you will get 3 parts

• . (this means the current directory your code is in)
• /usr/share/pear
• /usr/share/ph

Any attempts to include()/require() things, will look in these directories, in this order.

It is showing you that in the error message to let you know where it could NOT find the file you were trying to require()

That was the cause of error.

Now coming to solution

1. Step 1 : Find you php.ini file using command php --ini ( in my case : /etc/php5/cli/php.ini )
2. Step 2 : find include_path in vi using esc then press /include_path then enter
3. Step 3 : uncomment that line if commented and include your server directory, your path should look like this include_path = ".:/usr/share/php:/var/www/<directory>/"
4. Step 4 : Restart apache sudo service apache2 restart

This is it. Hope it helps.

(Tested for pandas 1.0.5)

           'C':['big','small','big','small','small']
         })

You need to provide a valid strict weak ordering comparison for the type stored in the queue, Person in this case. The default is to use std::less<T>, which resolves to something equivalent to operator<. This relies on it's own stored type having one. So if you were to implement

bool operator<(const Person& lhs, const Person& rhs); 

it should work without any further changes. The implementation could be

bool operator<(const Person& lhs, const Person& rhs)
{
  return lhs.age < rhs.age;
}

If the the type does not have a natural "less than" comparison, it would make more sense to provide your own predicate, instead of the default std::less<Person>. For example,

struct LessThanByAge
{
  bool operator()(const Person& lhs, const Person& rhs) const
  {
    return lhs.age < rhs.age;
  }
};

then instantiate the queue like this:

std::priority_queue<Person, std::vector<Person>, LessThanByAge> pq;

Concerning the use of std::greater<Person> as comparator, this would use the equivalent of operator> and have the effect of creating a queue with the priority inverted WRT the default case. It would require the presence of an operator> that can operate on two Person instances.

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

I got this error because I found out that I referenced jQuery twice.

The first time: on the master page (_Layout.cshtml) in ASP.NET MVC, and then again on one current page so I commented out the one on the master page.

If you are using ASP.NET MVC this snippet could help you

@*@Scripts.Render("~/bundles/jquery")*@//comment this line 
@Scripts.Render("~/bundles/bootstrap")
@RenderSection("scripts", required: false)

and in the current page I added these lines

<script src="~/scripts/jquery-1.10.2.js"></script>

<!-- #region datatables files -->
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.12/css/jquery.dataTables.min.css" />
<script src="//cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
<!-- #endregion -->

Hope this help you even if don't use ASP.NET MVC

On Cygwin -mcmodel=medium is already default and doesn't help. To me adding -Wl,--image-base -Wl,0x10000000 to GCC linker did fixed the error.

I believe this would work. It takes const char*'s as a parameter.

//params find and replace cannot be NULL
void FindAndReplace( std::string& source, const char* find, const char* replace )
{
   //ASSERT(find != NULL);
   //ASSERT(replace != NULL);
   size_t findLen = strlen(find);
   size_t replaceLen = strlen(replace);
   size_t pos = 0;

   //search for the next occurrence of find within source
   while ((pos = source.find(find, pos)) != std::string::npos)
   {
      //replace the found string with the replacement
      source.replace( pos, findLen, replace );

      //the next line keeps you from searching your replace string, 
      //so your could replace "hello" with "hello world" 
      //and not have it blow chunks.
      pos += replaceLen; 
   }
}

Thanks , but i found an alternative solution using ffmpeg:

def save():
    os.system("ffmpeg -r 1 -i img%01d.png -vcodec mpeg4 -y movie.mp4")

But thank you for your help :)

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

• NOLOCK is local to the table (or views etc)
• READ UNCOMMITTED is per session/connection

As for guidelines... a random search from StackOverflow and the electric interweb...

• Is the NOLOCK (Sql Server hint) bad practice?
• When is it appropriate to use NOLOCK?
• Get rid of those NOLOCK hints…

With the command:

sudo apt-get remove --purge mysql\*

you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).

You can list all installed mysql packages with the command:

sudo dpkg -l | grep -i mysql

For more cleanup of the package cache, you can use the command:

sudo apt-get clean

Also, remember to use the command:

sudo updatedb

Otherwise the "locate" command will display old data.

To install mysql again, use the following command:

sudo apt-get install libmysqlclient-dev mysql-client

This will install the mysql client, libmysql and its headers files.

To install the mysql server, use the command:

sudo apt-get install mysql-server

Enqueue means to add an element, dequeue to remove an element.

var stackInput= []; // First stack
var stackOutput= []; // Second stack

// For enqueue, just push the item into the first stack
function enqueue(stackInput, item) {
  return stackInput.push(item);
}

function dequeue(stackInput, stackOutput) {
  // Reverse the stack such that the first element of the output stack is the
  // last element of the input stack. After that, pop the top of the output to
  // get the first element that was ever pushed into the input stack
  if (stackOutput.length <= 0) {
    while(stackInput.length > 0) {
      var elementToOutput = stackInput.pop();
      stackOutput.push(elementToOutput);
    }
  }

  return stackOutput.pop();
}

I was trying to access my web pages on specific port number and tried much things, but I've found the port was filtered by firewall. Just added a bypass rule and everything was done.

Check you proxy settings in TortoiseSVN->Settings->Network.

Maybe they are configured differently than in your web browser.

The maximum SqlDbType.VarChar size is 2147483647.

If you would use a generic oledb connection instead of sql, I found here there is also a LongVarChar datatype. Its max size is 2147483647.

cmd.Parameters.Add("@blah", OleDbType.LongVarChar, -1).Value = "very big string";

The best way to do it is to put the Django admin templates inside your project. So your templates would be in templates/admin while the stock Django admin templates would be in say template/django_admin. Then, you can do something like the following:

templates/admin/change_form.html

{% extends 'django_admin/change_form.html' %}

Your stuff here

If you're worried about keeping the stock templates up to date, you can include them with svn externals or similar.

Since this is a Python 3 project, you only need to delete __pycache__ directories -- all .pyc/.pyo files are inside them.

find . -type d -name __pycache__ -exec rm -r {} \+

or its simpler form,

find . -type d -name __pycache__ -delete

which didn't work for me for some reason (files were deleted but directories weren't), so I'm including both for the sake of completeness.

Alternatively, if you're doing this in a directory that's under revision control, you can tell the RCS to ignore __pycache__ folders recursively. Then, at the required moment, just clean up all the ignored files. This will likely be more convenient because there'll probably be more to clean up than just __pycache__.

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

just use a Button with android:drawableRight properties like this:

<Button android:id="@+id/btnNovaCompra" android:layout_width="wrap_content"
        android:text="@string/btn_novaCompra"
        android:gravity="center"
        android:drawableRight="@drawable/shoppingcart"
        android:layout_height="wrap_content"/>

One method to do this is to add:

pointer-events: none;

to the element, you want to disable hover on.

(Note: this also disables javascript events on that element too, click events will actually fall through to the element behind ).

Browser Support ( 98.12% as of Jan 1, 2021 )

This seems to be much cleaner

/**
 * This allows you to disable hover events for any elements
*/
.disabled {
  pointer-events: none;  /* <----------- */
  opacity: 0.2;
}

.button {
  border-radius: 30px;
  padding: 10px 15px;
  border: 2px solid #000;
  color: #FFF;
  background: #2D2D2D;
  text-shadow: 1px 1px 0px #000;
  cursor: pointer;
  display: inline-block;
  margin: 10px;
}

.button-red:hover {
  background: red;
}

.button-green:hover {
  background:green;  
}

<div class="button button-red">I'm a red button hover over me</div>

<br />

<div class="button button-green">I'm a green button hover over me</div>

<br />

<div class="button button-red disabled">I'm a disabled red button</div>

<br />

<div class="button button-green disabled">I'm a disabled green button</div>

the mySql blob class has the following function :

blob.getBytes

use it like this:

//(assuming you have a ResultSet named RS)
Blob blob = rs.getBlob("SomeDatabaseField");

int blobLength = (int) blob.length();  
byte[] blobAsBytes = blob.getBytes(1, blobLength);

//release the blob and free up memory. (since JDBC 4.0)
blob.free();

My 2 cents.

This is a loaded question imho. A rule of thumb I use to is see how this function will be called. If the caller is something I have control over then , its ok to assume that it will be called with the right parameters and with proper initialization.

On the other hand if its some client I don't control then it is a good idea to do thorough error checking.

Your code contains two problems:

• The equality operator in JavaScript is ==, not =.
• jQuery.text() joins all text nodes of matched elements into a single string. If you have two successive elements, of which the first contains 'some' and the second contains 'Text', then your code will incorrectly think that there exists an element that contains 'someText'.

I suggest the following instead:

if ($('#field > div.field-item:contains("someText")').length > 0) {
    $("#somediv").addClass("thisClass");
}

just pass the columnName as parameter of YEAR

SELECT YEAR(ASOFDATE) from PSASOFDATE;

another is to use DATE_FORMAT

SELECT DATE_FORMAT(ASOFDATE, '%Y') from PSASOFDATE;

I bet the value is varchar with the format MM/dd/YYYY, it that's the case,

SELECT YEAR(STR_TO_DATE('11/15/2012', '%m/%d/%Y'));

Here are some reference for you:

Primary & foreign key Constraint.

Primary Key: A primary key is a field or combination of fields that uniquely identify a record in a table, so that an individual record can be located without confusion.

Foreign Key: A foreign key (sometimes called a referencing key) is a key used to link two tables together. Typically you take the primary key field from one table and insert it into the other table where it becomes a foreign key (it remains a primary key in the original table).

Index, on the other hand, is an attribute that you can apply on some columns so that the data retrieval done on those columns can be speed up.

Use javax.servlet.http.HttpServletResponse class

Example:

javax.servlet.http.HttpServletResponse.SC_UNAUTHORIZED //401
javax.servlet.http.HttpServletResponse.SC_INTERNAL_SERVER_ERROR //500

import subprocess
output = str(subprocess.Popen("ntpq -p",shell = True,stdout = subprocess.PIPE, 
stderr = subprocess.STDOUT).communicate()[0])

This is one line solution

I assume you are using TCP sockets for the client-server interaction? One way to send different types of data to the server and have it be able to differentiate between the two is to dedicate the first byte (or more if you have more than 256 types of messages) as some kind of identifier. If the first byte is one, then it is message A, if its 2, then its message B. One easy way to send this over the socket is to use DataOutputStream/DataInputStream:

Client:

Socket socket = ...; // Create and connect the socket
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

// Send first message
dOut.writeByte(1);
dOut.writeUTF("This is the first type of message.");
dOut.flush(); // Send off the data

// Send the second message
dOut.writeByte(2);
dOut.writeUTF("This is the second type of message.");
dOut.flush(); // Send off the data

// Send the third message
dOut.writeByte(3);
dOut.writeUTF("This is the third type of message (Part 1).");
dOut.writeUTF("This is the third type of message (Part 2).");
dOut.flush(); // Send off the data

// Send the exit message
dOut.writeByte(-1);
dOut.flush();

dOut.close();

Server:

Socket socket = ... // Set up receive socket
DataInputStream dIn = new DataInputStream(socket.getInputStream());

boolean done = false;
while(!done) {
  byte messageType = dIn.readByte();

  switch(messageType)
  {
  case 1: // Type A
    System.out.println("Message A: " + dIn.readUTF());
    break;
  case 2: // Type B
    System.out.println("Message B: " + dIn.readUTF());
    break;
  case 3: // Type C
    System.out.println("Message C [1]: " + dIn.readUTF());
    System.out.println("Message C [2]: " + dIn.readUTF());
    break;
  default:
    done = true;
  }
}

dIn.close();

Obviously, you can send all kinds of data, not just bytes and strings (UTF).

Note that writeUTF writes a modified UTF-8 format, preceded by a length indicator of an unsigned two byte encoded integer giving you 2^16 - 1 = 65535 bytes to send. This makes it possible for readUTF to find the end of the encoded string. If you decide on your own record structure then you should make sure that the end and type of the record is either known or detectable.

One of the above answer states to convert XML String to bytes which is not needed. Instead you can can use InputSource and supply it with StringReader.

String xmlStr = "<message>HELLO!</message>";
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(xmlStr)));
System.out.println(doc.getFirstChild().getNodeValue());

[.\n] does not work because . has no special meaning inside of [], it just means a literal .. (.|\n) would be a way to specify "any character, including a newline". If you want to match all newlines, you would need to add \r as well to include Windows and classic Mac OS style line endings: (.|[\r\n]).

That turns out to be somewhat cumbersome, as well as slow, (see KrisWebDev's answer for details), so a better approach would be to match all whitespace characters and all non-whitespace characters, with [\s\S], which will match everything, and is faster and simpler.

In general, you shouldn't try to use a regexp to match the actual HTML tags. See, for instance, these questions for more information on why.

Instead, try actually searching the DOM for the tag you need (using jQuery makes this easier, but you can always do document.getElementsByTagName("pre") with the standard DOM), and then search the text content of those results with a regexp if you need to match against the contents.

Most of the editors take some kind of shortcut to comment out blocks of code. The default editors use something like command or control and single quote to comment out selected lines of code. In RStudio it's Command or Control+/. Check in your editor.

It's still commenting line by line, but they also uncomment selected lines as well. For the Mac RGUI it's command-option ' (I'm imagining windows is control option). For Rstudio it's just Command or Control + Shift + C again.

These shortcuts will likely change over time as editors get updated and different software becomes the most popular R editors. You'll have to look it up for whatever software you have.

I'm going to expand your question a bit and also include the compile function.

• compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link' attribute is ignored if the 'compile' attribute is defined.)

• link function - normally use for registering listener callbacks (i.e., $watch expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>, the link function is executed after the <li> template (tElement) has been cloned (into an iElement) for that particular <li> element. A $watch allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.

• controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
  
  For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this (rather than on $scope), please see 'this' vs $scope in AngularJS controllers.

In general, you can put methods, $watches, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.

For UUID4 I make it that there are approximately as many IDs as there are grains of sand in a cube-shaped box with sides 360,000km long. That's a box with sides ~2 1/2 times longer than Jupiter's diameter.

Working so someone can tell me if I've messed up units:

• volume of grain of sand 0.00947mm^3 (Guardian)
• UUID4 has 122 random bits -> 5.3e36 possible values (wikipedia)
• volume of that many grains of sand = 5.0191e34 mm^3 or 5.0191e+25m^3
• side length of cubic box with that volume = 3.69E8m or 369,000km
• diameter of Jupiter: 139,820km (google)

Edit: The bitset stuff below is maybe an interesting read, but the answer itself is a bit dated. Some of this functionality is changing around in 2.x. Also Slawek points out in another answer that the terms query is an easy way to DRY up the search in this case. Refactored at the end for current best practices. —nz

You'll probably want a Bool Query (or more likely Filter alongside another query), with a should clause.

The bool query has three main properties: must, should, and must_not. Each of these accepts another query, or array of queries. The clause names are fairly self-explanatory; in your case, the should clause may specify a list filters, a match against any one of which will return the document you're looking for.

From the docs:

In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

Here's an example of what that Bool query might look like in isolation:

{
  "bool": {
    "should": [
      { "term": { "tag": "c" }},
      { "term": { "tag": "d" }}
    ]
  }
}

And here's another example of that Bool query as a filter within a more general-purpose Filtered Query:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "bool": {
        "should": [
          { "term": { "tag": "c" }},
          { "term": { "tag": "d" }}
        ]
      }
    }
  }
}

Whether you use Bool as a query (e.g., to influence the score of matches), or as a filter (e.g., to reduce the hits that are then being scored or post-filtered) is subjective, depending on your requirements.

It is generally preferable to use Bool in favor of an Or Filter, unless you have a reason to use And/Or/Not (such reasons do exist). The Elasticsearch blog has more information about the different implementations of each, and good examples of when you might prefer Bool over And/Or/Not, and vice-versa.

Elasticsearch blog: All About Elasticsearch Filter Bitsets

Update with a refactored query...

Now, with all of that out of the way, the terms query is a DRYer version of all of the above. It does the right thing with respect to the type of query under the hood, it behaves the same as the bool + should using the minimum_should_match options, and overall is a bit more terse.

Here's that last query refactored a bit:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "terms": {
        "tag": [ "c", "d" ],
        "minimum_should_match": 1
      }
    }
  }
}

Since Java 10 it is possible to use

Map.copyOf

for creating a shallow copy, which is also immutable. (Here is its Javadoc). For a deep copy, as mentioned in this answer you, need some kind of value mapper to make a safe copy of values. You don't need to copy keys though, since they must be immutable.

I just did this for fun

    >>> s = 'a,b,c,d'
    >>> [item[::-1] for item in s[::-1].split(',', 1)][::-1]
    ['a,b,c', 'd']

Caution: Refer to the first comment in below where this answer can go wrong.

Also you can use HRTime package. It has a class StopWatch.

Since Node v11.0.0 fs promises are available natively without promisify:

const fs = require('fs').promises;
async function loadMonoCounter() {
    const data = await fs.readFile("monolitic.txt", "binary");
    return new Buffer(data);
}

The indexes capable of placing a unique key constraint on a table are PRIMARY and UNIQUE indexes.

To remove the unique key constraint on a column but keep the index, you could remove and recreate the index with type INDEX.

Note that it is a good idea for all tables to have an index marked PRIMARY.

With this, you can perform some code in the get or set scope.

private string _myProperty;
public string myProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

You also can use automatic properties:

public string myProperty
{
    get;
    set;
}

And .Net Framework will manage for you. It was create because it is a good pratice and make it easy to do.

You also can control the visibility of these scopes, for sample:

public string myProperty
{
    get;
    private set;
}

public string myProperty2
{
    get;
    protected set;
}

public string myProperty3
{
    get; 
}

Update

Now in C# you can initialize the value of a property. For sample:

public int Property { get; set; } = 1;

If also can define it and make it readonly, without a set.

public int Property { get; } = 1;

And finally, you can define an arrow function.

public int Property => GetValue();

The fix for me was to put "log4j.properties" into the "src" folder.

From Increase MySQL connection limit:-

MySQL’s default configuration sets the maximum simultaneous connections to 100. If you need to increase it, you can do it fairly easily:

For MySQL 3.x:

# vi /etc/my.cnf
set-variable = max_connections = 250

For MySQL 4.x and 5.x:

# vi /etc/my.cnf
max_connections = 250

Restart MySQL once you’ve made the changes and verify with:

echo "show variables like 'max_connections';" | mysql

EDIT:-(From comments)

The maximum concurrent connection can be maximum range: 4,294,967,295. Check MYSQL docs

Since .NET Framework 4.5 and .NET Standard 1.0 you should use WebUtility.UrlEncode. Advantages over alternatives:

1. It is part of .NET Framework 4.5+, .NET Core 1.0+, .NET Standard 1.0+, UWP 10.0+ and all Xamarin platforms as well. HttpUtility, while being available in .NET Framework earlier (.NET Framework 1.1+), becomes available on other platforms much later (.NET Core 2.0+, .NET Standard 2.0+) and it still unavailable in UWP (see related question).

2. In .NET Framework, it resides in System.dll, so it does not require any additional references, unlike HttpUtility.

3. It properly escapes characters for URLs, unlike Uri.EscapeUriString (see comments to drweb86's answer).

4. It does not have any limits on the length of the string, unlike Uri.EscapeDataString (see related question), so it can be used for POST requests, for example.

Short answer: classmaps are static while PSR autoloading is dynamic.

If you don't want to use classmaps, use PSR autoloading instead.

Just add a >NUL at the end of the lines producing the messages.

For example,

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >NUL

go to FileZilla and select which folder you will be give 777 permission, then right click set permission 777 and select check box, then ok.

Andres Ilich has it right. Just in case someone misses his comment...

A.) If you only have one line of text:

div_x000D_
{_x000D_
  height: 200px;_x000D_
  line-height: 200px; /* <-- this is what you must define */_x000D_
}

<div>vertically centered text</div>

B.) If you have multiple lines of text:

div_x000D_
{_x000D_
  height: 200px;_x000D_
  line-height: 200px;_x000D_
}_x000D_
_x000D_
span_x000D_
{_x000D_
  display: inline-block;_x000D_
  vertical-align: middle;_x000D_
  line-height: 18px; /* <-- adjust this */_x000D_
}

<div><span>vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text vertically centered text</span></div>

Just to rule out the possibility you aren't actually trying to see the fragment on a GET/POST and actually want to know how to access that part of a URI object you have within your server-side code, it is under Uri.Fragment (MSDN docs).

You just have to write this:

 private PowerManager.WakeLock wl;

    protected void onCreate(Bundle savedInstanceState) {
               super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
            wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "DoNjfdhotDimScreen");
    }//End of onCreate

            @Override
        protected void onPause() {
            super.onPause();
            wl.release();
        }//End of onPause

        @Override
        protected void onResume() {
            super.onResume();
            wl.acquire();
        }//End of onResume

and then add permission in the manifest file

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

Now your activity will always be awake. You can do other things like w1.release() as per your requirement.

For me the following works good. Just add it. You can edit it as per your requirement. This is just a nice trick I use.

text-shadow : 0 0 0 #your-font-color;

foreach (EMyEnum val in Enum.GetValues(typeof(EMyEnum)))
{
   Console.WriteLine(val);
}

Try using BindingExpression.UpdateTarget()

true, this option is not available in any version of MS ppt.Now the solution is that You put your different sized slide in other file and put a hyperlink in first file.

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.

Here is one breakdown:

Front-end tier -> User Interface layer usually consisting of a mix of HTML, Javascript, CSS, Flash, and various server-side code like ASP.Net, classic ASP, PHP, etc. Think of this as being closest to the user in terms of code.

Middleware, middle-tier -> One tier back, generally referred to as the "plumbing" part of a system. Java and C# are common languages for writing this part that could be viewed as the glue between the UI and the data and can be webservices or WCF components or other SOA components possibly.

Back-end tier -> Databases and other data stores are generally at this level. Oracle, MS-SQL, MySQL, SAP, and various off-the-shelf pieces of software come to mind for this piece of software that is the final processing of the data.

Overlap can exist between any of these as you could have everything poured into one layer like an ASP.Net website that uses the built-in AJAX functionality that generates Javascript while the code behind may contain database commands making the code behind contain both middle and back-end tiers. Alternatively, one could use VBScript to act as all the layers using ADO objects and merging all three tiers into one.

Similarly, taking middleware and either front or back-end can be combined in some cases.

Bottlenecks generally have a few different levels to them:

1) Database or back-end processing -> This can vary from payroll or sales or other tasks where the throughput to the database is bogging things down.

2) Middleware bottlenecks -> This would be where some web service may be hitting capacity but the front and back ends have bandwidth to handle more traffic. Alternatively, there may be some server that is part of a system that isn't quite the UI part or the raw data that can be a bottleneck using something like Biztalk or MSMQ.

3) Front-end bottlenecks -> This could client or server-side issues. For example, if you took a low-end PC and had it load a web page that consisted of a lot of data being downloaded, the client could be where the bottleneck is. Similarly, the server could be queuing up requests if it is getting hammered with requests like what Amazon.com or other high-traffic websites may get at times.

Some of this is subject to interpretation, so it isn't perfect by any means and YMMV.

EDIT: Something to consider is that some systems can have multiple front-ends or back-ends. For example, a content management system will likely have a way for site visitors to view the content that is a front-end but what about how content editors are able to change the data on the site? The ability to pull up this data could be seen as front-end since it is a UI component or it could be seen as a back-end since it is used by internal users rather than the general public viewing the site. Thus, there is something to be said for context here.

Map does not supports duplicate keys. you can use collection as value against same key.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value.

Documentation

you can use any kind of List or Set implementation according to your requirement.

If your values might be also duplicate you can go with ArrayList or LinkedList, in case values are unique you can use HashSet or TreeSet etc.

Also In google guava collection library Multimap is available, it is a collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values. You can visualize the contents of a multimap either as a map from keys to nonempty collections of values:

a ? 1, 2
b ? 3  

Example -

ListMultimap<String, String> multimap = ArrayListMultimap.create();
multimap.put("a", "1");
multimap.put("a", "2");
multimap.put("c", "3");

You might want to modify your jQuery code a bit to '#demolist li a' so it specifically selects the text that is in the link rather than the text that is in the li element. That would allow you to have a sub-menu without causing issues. Also since your are specifically selecting the a tag you can access it with $(this).text();.

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

A simple way of generating a printable report from a Datagridview is to place the datagridview on a Panel object. It is possible to draw a bitmap of the panel.

Here's how I do it.

'create the bitmap with the dimentions of the Panel Dim bmp As New Bitmap(Panel1.Width, Panel1.Height)

'draw the Panel to the bitmap "bmp" Panel1.DrawToBitmap(bmp, Panel1.ClientRectangle)

I create a multi page tiff by "breaking my datagridview items into pages. this is how i detect the start of a new page:

'i add the rows to my datagrid one at a time and then check if the scrollbar is active. 'if the scrollbar is active i save the row to a variable and then i remove it from the 'datagridview and roll back my counter integer by one(thus the next run will include this 'row.

Private Function VScrollBarVisible() As Boolean
    Dim ctrl As New Control
    For Each ctrl In DataGridView_Results.Controls
        If ctrl.GetType() Is GetType(VScrollBar) Then
            If ctrl.Visible = True Then
                Return True
            Else
                Return False
            End If
        End If
    Next
    Return Nothing
End Function

I hope this helps

def dupe(str1):
    s=set(str1)

    return "".join(s)
str1='geeksforgeeks'
a=dupe(str1)
print(a)

works well if order is not important.

Try using TempData:

public ActionResult Create(FormCollection collection) {
  ...
  TempData["notice"] = "Successfully registered";
  return RedirectToAction("Index");
  ...
}

Then, in your Index view, or master page, etc., you can do this:

<% if (TempData["notice"] != null) { %>
  <p><%= Html.Encode(TempData["notice"]) %></p>
<% } %>

Or, in a Razor view:

@if (TempData["notice"] != null) {
  <p>@TempData["notice"]</p>
}

Quote from MSDN (page no longer exists as of 2014, archived copy here):

An action method can store data in the controller's TempDataDictionary object before it calls the controller's RedirectToAction method to invoke the next action. The TempData property value is stored in session state. Any action method that is called after the TempDataDictionary value is set can get values from the object and then process or display them. The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request.

Here's the strsplit solution if s is a vector:

> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"

Following are the steps to push Docker Image to Private Repository of DockerHub

1- First check Docker Images using command

docker images

2- Check Docker Tag command Help

docker tag help

3- Now Tag a name to your created Image

docker tag localImgName:tagName DockerHubUser\Private-repoName:tagName(tag name is optional. Default name is latest)

4- Before pushing Image to DockerHub Private Repo, first login to DockerHub using command

docker login [provide dockerHub username and Password to login]

5- Now push Docker Image to your private Repo using command

docker push [options] ImgName[:tag] e.g docker push DockerHubUser\Private-repoName:tagName

6- Now navigate to the DockerHub Private Repo and you will see Docker image is pushed on your private Repository with name written as TagName in previous steps

Wouldn't it be significantly more readable to do a positive match and reject those strings - rather than match the negative to find strings to accept?

There's an approach using the Microsoft Templating approach that's currently under proposal for inclusion into jQuery core. There's more power in using the templating so for the simplest scenario it may not be the best option. For more details see Scott Gu's post outlining the features.

First include the templating js file, available from github.

<script src="Scripts/jquery.tmpl.js" type="text/javascript" />

Next set-up a template

<script id="templateOptionItem" type="text/html">
    <option value=\'{{= Value}}\'>{{= Text}}</option>
</script>

Then with your data call the .render() method

var someData = [
    { Text: "one", Value: "1" },
    { Text: "two", Value: "2" },
    { Text: "three", Value: "3"}];

$("#templateOptionItem").render(someData).appendTo("#mySelect");

I've blogged this approach in more detail.

If you want to pursue a "simple" solution, you might find this class I put together useful:

http://www.architectshack.com/TextFileEncodingDetector.ashx

It does the BOM detection automatically first, and then tries to differentiate between Unicode encodings without BOM, vs some other default encoding (generally Windows-1252, incorrectly labelled as Encoding.ASCII in .Net).

As noted above, a "heavier" solution involving NCharDet or MLang may be more appropriate, and as I note on the overview page of this class, the best is to provide some form of interactivity with the user if at all possible, because there simply is no 100% detection rate possible!

         * Simple class to handle text file encoding woes (in a primarily English-speaking tech 
         *      world).
         * 
         *  - This code is fully managed, no shady calls to MLang (the unmanaged codepage
         *      detection library originally developed for Internet Explorer).
         * 
         *  - This class does NOT try to detect arbitrary codepages/charsets, it really only
         *      aims to differentiate between some of the most common variants of Unicode 
         *      encoding, and a "default" (western / ascii-based) encoding alternative provided
         *      by the caller.
         *      
         *  - As there is no "Reliable" way to distinguish between UTF-8 (without BOM) and 
         *      Windows-1252 (in .Net, also incorrectly called "ASCII") encodings, we use a 
         *      heuristic - so the more of the file we can sample the better the guess. If you 
         *      are going to read the whole file into memory at some point, then best to pass 
         *      in the whole byte byte array directly. Otherwise, decide how to trade off 
         *      reliability against performance / memory usage.
         *      
         *  - The UTF-8 detection heuristic only works for western text, as it relies on 
         *      the presence of UTF-8 encoded accented and other characters found in the upper 
         *      ranges of the Latin-1 and (particularly) Windows-1252 codepages.
         *  
         *  - For more general detection routines, see existing projects / resources:
         *    - MLang - Microsoft library originally for IE6, available in Windows XP and later APIs now (I think?)
         *      - MLang .Net bindings: http://www.codeproject.com/KB/recipes/DetectEncoding.aspx
         *    - CharDet - Mozilla browser's detection routines
         *      - Ported to Java then .Net: http://www.conceptdevelopment.net/Localization/NCharDet/

I took the liberty of putting together a jsFiddle illustrating the functionality of building a custom form using jQuery. Here it is...

EDIT: Updated the jsFiddle to include remove buttons for each field.

EDIT: As per the request in the last comment, code from the jsFiddle is below.

EDIT: As per Abhishek's comment, I have updated the jsFiddle (and code below) to cater for scenarios where duplicate field IDs might arise.

HTML:

<fieldset id="buildyourform">
    <legend>Build your own form!</legend>
</fieldset>
<input type="button" value="Preview form" class="add" id="preview" />
<input type="button" value="Add a field" class="add" id="add" />

JavaScript:

$(document).ready(function() {
    $("#add").click(function() {
        var lastField = $("#buildyourform div:last");
        var intId = (lastField && lastField.length && lastField.data("idx") + 1) || 1;
        var fieldWrapper = $("<div class=\"fieldwrapper\" id=\"field" + intId + "\"/>");
        fieldWrapper.data("idx", intId);
        var fName = $("<input type=\"text\" class=\"fieldname\" />");
        var fType = $("<select class=\"fieldtype\"><option value=\"checkbox\">Checked</option><option value=\"textbox\">Text</option><option value=\"textarea\">Paragraph</option></select>");
        var removeButton = $("<input type=\"button\" class=\"remove\" value=\"-\" />");
        removeButton.click(function() {
            $(this).parent().remove();
        });
        fieldWrapper.append(fName);
        fieldWrapper.append(fType);
        fieldWrapper.append(removeButton);
        $("#buildyourform").append(fieldWrapper);
    });
    $("#preview").click(function() {
        $("#yourform").remove();
        var fieldSet = $("<fieldset id=\"yourform\"><legend>Your Form</legend></fieldset>");
        $("#buildyourform div").each(function() {
            var id = "input" + $(this).attr("id").replace("field","");
            var label = $("<label for=\"" + id + "\">" + $(this).find("input.fieldname").first().val() + "</label>");
            var input;
            switch ($(this).find("select.fieldtype").first().val()) {

Inside the input tag you can add autoFocus={true} for anyone using jsx/react.

<input
 type="email"
 name="email"
 onChange={e => setEmail(e.target.value)}
 value={email}
 placeholder={"Email..."}
 autoFocus={true}
/>

use DateTime.Now

try this:

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

There are multiple solution for this Lazy Initialisation issue -

1) Change the association Fetch type from LAZY to EAGER but this is not a good practice because this will degrade the performance.

2) Use FetchType.LAZY on associated Object and also use Transactional annotation in your service layer method so that session will remain open and when you will call topicById.getComments(), child object(comments) will get loaded.

3) Also, please try to use DTO object instead of entity in controller layer. In your case, session is closed at controller layer. SO better to convert entity to DTO in service layer.

The currently chosen best answer is too fuzzy to be reliable.

This feels to me like a fairly safe way to do it:

(Javascript: using jQuery to write it simpler)

$('#form1').submit(doubleSubmit);

function doubleSubmit(e1) {
    e1.preventDefault();
    e1.stopPropagation();
    var post_form1 = $.post($(this).action, $(this).serialize());

    post_form1.done(function(result) {
            // would be nice to show some feedback about the first result here
            $('#form2').submit();
        });
};

Post the first form without changing page, wait for the process to complete. Then post the second form. The second post will change the page, but you might want to have some similar code also for the second form, getting a second deferred object (post_form2?).

I didn't test the code, though.

Python is a case-sensitive language. All Python keywords are lowercase. Use if, not If.

Also, don't put a colon after the call to print(). Also, indent the print() and exit() calls, as Python uses indentation rather than brackets to represent code blocks.

And also, proceed = "y" or "Y" won't do what you want. Use proceed = "y" and if answer.lower() == proceed:, or something similar.

There's also the fact that your program will exit as long as the input value is not the single character "y" or "Y", which contradicts the prompting of "N" for the alternate case. Instead of your else clause there, use elif answer.lower() == info_incorrect:, with info_incorrect = "n" somewhere beforehand. Then just reprompt for the response or something if the input value was something else.

I'd recommend going through the tutorial in the Python documentation if you're having this much trouble the way you're learning now. http://docs.python.org/tutorial/index.html

A dictionary probably isn't what you should be using in this case. A more full featured library would be a better alternative. Probably a real database. The easiest would be sqlite. You can keep the whole thing in memory by passing in the string ':memory:' instead of a filename.

If you do want to continue down this path, you can do it with the extra attributes in the key or the value. However a dictionary can't be the key to a another dictionary, but a tuple can. The docs explain what's allowable. It must be an immutable object, which includes strings, numbers and tuples that contain only strings and numbers (and more tuples containing only those types recursively...).

You could do your first example with d = {('apple', 'red') : 4}, but it'll be very hard to query for what you want. You'd need to do something like this:

#find all apples
apples = [d[key] for key in d.keys() if key[0] == 'apple']

#find all red items
red = [d[key] for key in d.keys() if key[1] == 'red']

#the red apple
redapples = d[('apple', 'red')]

SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

Another approach would be to deserialize into a java.util.Map, and then just modify the Java Map as wanted. This separates the Java-side data handling from the data transport mechanism (JSON), which is how I prefer to organize my code: using JSON for data transport, not as a replacement data structure.

Using DateTime:

$given = new DateTime("2014-12-12 14:18:00");
echo $given->format("Y-m-d H:i:s e") . "\n"; // 2014-12-12 14:18:00 Asia/Bangkok

$given->setTimezone(new DateTimeZone("UTC"));
echo $given->format("Y-m-d H:i:s e") . "\n"; // 2014-12-12 07:18:00 UTC

I use JQuery so I can use the readonly attribute on checkboxes.

//This will make all read-only check boxes truly read-only
$('input[type="checkbox"][readonly]').on("click.readonly", function(event){event.preventDefault();}).css("opacity", "0.5");

If you want the checkbox to be editable again then you need to do the following for the specific checkbox.

$('specific checkbox').off('.readonly').removeAttr("readonly").css("opacity", "1")

I want to show you my implementation: ReadyCLI

Advantages:

• for lazy programmers: a very small number of classes to learn, just see the two small examples on the README in the repository and you are already at 90% of learning; just start coding your CLI/Parser without any other knowledge; ReadyCLI allows coding CLIs in the most natural way;
• it is designed with Developer Experience in mind; it largely uses the Builder design pattern and functional interfaces for Lambda Expressions, to allow a very quick coding;
• it supports Options, Flags and Sub-Commands;
• it allows to parse arguments from command-line and to build more complex and interactive CLIs;
• a CLI can be started on Standard I/O just as easily as on any other I/O interface, such as sockets;
• it gives great support for documentation of commands.

I developed this project as I needed new features (options, flag, sub-commands) and that could be used in the simplest possible way in my projects.

For a popular alternative to colors that doesn't mess with the built-in methods of the String object, I recommend checking out cli-color.

Includes both colors and chainable styles such as bold, italic, and underline.

For a comparison of various modules in this category, see here.

For decimal values you can use DecimalFormat

import java.text.*;

public class DecimalFormatDemo {

   static public void customFormat(String pattern, double value ) {
      DecimalFormat myFormatter = new DecimalFormat(pattern);
      String output = myFormatter.format(value);
      System.out.println(value + "  " + pattern + "  " + output);
   }

   static public void main(String[] args) {

      customFormat("###,###.###", 123456.789);
      customFormat("###.##", 123456.789);
      customFormat("000000.000", 123.78);
      customFormat("$###,###.###", 12345.67);  
   }
}

and output will be:

123456.789  ###,###.###   123,456.789
123456.789  ###.##        123456.79
123.78      000000.000    000123.780
12345.67    $###,###.###  $12,345.67

You can get IP Genymotion Virtual Device Manager,then use the command like this

adb connect your ip

Old question, but I had this issue as well, so after assigning the Text property, calling Refresh() will update the text.

Label1.Text = "Du har nu lånat filmen:" + test;
Refresh();

There is a package random_word could implement this request very conveniently:

 $ pip install random-word

from random_word import RandomWords
r = RandomWords()

# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()

You can also use this node module called js-xlsx

1) Install module
npm install xlsx

2) Import module + code snippet

var XLSX = require('xlsx')
var workbook = XLSX.readFile('Master.xlsx');
var sheet_name_list = workbook.SheetNames;
var xlData = XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list[0]]);
console.log(xlData);

WebRupee is a web API for the Indian currency symbol. It provides a simple, cross browser method for using the Rrupee symbol on your webpage, blog or anywhere on the web.

Here is a method for printing the Indian currency symbol:

<html>
<head>
    <link rel="stylesheet" type="text/css" href="http://cdn.webrupee.com/font">
    <script src=http://cdn.webrupee.com/js type=”text/javascript”></script>
</head>
<body>
    Rupee Symbol: <span class="WebRupee">Rs.</span> 200

This means if somebody copies text from your site and pastes it somewhere else, he will see Rs and not some other or blank character.

You can now also use the new Rupee unicode symbol — U+20B9 INDIAN RUPEE SIGN. It can be used in this manner:

<span class="WebRupee">&#x20B9;</span> 500

Just include the following script and it will update all the "Rs" / "Rs." for you:

<script src="http://cdn.webrupee.com/js" type="text/javascript"></script>

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

faster way will require additional space .

For example:

1. put all items in one list into a HashSet ( you have to implement the hash function by yourself to use object.getAttributeSame() )

2. Go through the other list and check if any item is in the HashSet.

In this way each object is visited at most once. and HashSet is fast enough to check or insert any object in O(1).

Try this more succinct code:

Sub LoopOverEachColumn()
    Dim WS As Worksheet
    For Each WS In ThisWorkbook.Worksheets
        ResizeColumns WS
    Next WS
End Sub

Private Sub ResizeColumns(WS As Worksheet)
    Dim StrSize As String
    Dim ColIter As Long
    StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
    For ColIter = 1 To 15
        WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
    Next ColIter
End Sub

If you want additional columns, just change 1 to 15 to 1 to X where X is the column index of the column you want, and append the column size you want to StrSize.

For example, if you want P:P to have a width of 25, just add ;25 to StrSize and change ColIter... to ColIter = 1 to 16.

Hope this helps.

Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:

+!+[] + [+[]] // "10"

-~[] + [+[]] // "10"

//========== Explanation ==========\\

+!+[] : +[] Converts to 0. !0 converts to true. +true converts to 1. -~[] = -(-1) which is 1

[+[]] : +[] Converts to 0. [0] is an array with a single element 0.

Then JS evaluates the 1 + [0], thus Number + Array expression. Then the ECMA specification works: + operator converts both operands to a string by calling the toString()/valueOf() functions from the base Object prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.

Some examples:

1 + {} //    "1[object Object]"
1 + [] //    "1"
1 + new Date() //    "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"

There's a nice exception that two Objects addition results in NaN:

[] + []   //    ""
[1] + [2] //    "12"
{} + {}   //    NaN
{a:1} + {b:2}     //    NaN
[1, {}] + [2, {}] //    "1,[object Object]2,[object Object]"

  private File convertMultiPartToFile(MultipartFile file ) throws IOException
    {
        File convFile = new File( file.getOriginalFilename() );
        FileOutputStream fos = new FileOutputStream( convFile );
        fos.write( file.getBytes() );
        fos.close();
        return convFile;
    }

Don'y forget that if you are mixing grouped (ie. SUM) fields and non-grouped fields, you need to GROUP BY one of the non-grouped fields.

Try this:

SELECT SUM(something) AS fieldname
FROM tablename
ORDER BY fieldname

OR this:

SELECT Field1, SUM(something) AS Field2
FROM tablename
GROUP BY Field1
ORDER BY Field2

And you can always do a derived query like this:

SELECT
   f1, f2
FROM
    (
        SELECT SUM(x+y) as f1, foo as F2
        FROM tablename 
        GROUP BY f2
    ) as table1
ORDER BY 
    f1

Many possibilities!

This is the only comprehensive and reliable way I've found to do this.

Assume you want to merge "tag_1.0" into "mybranch".

    $git checkout tag_1.0 (will create a headless branch)
    $git branch -D tagbranch (make sure this branch doesn't already exist locally)
    $git checkout -b tagbranch
    $git merge -s ours mybranch
    $git commit -am "updated mybranch with tag_1.0"
    $git checkout mybranch
    $git merge tagbranch

$string = '9,[email protected],8';
$array = explode(',', $string);

For more complicated situations, you may need to use preg_split.

Open IIS manager, select Application Pools, select the application pool you are using, click on Advanced Settings in the right-hand menu. Under General, set "Enable 32-Bit Applications" to "True".

I use printf, is shorter as it doesn't need flags to do the work:

printf "\rMy static $myvars composed text"

First Convert the date to float (which displays the numeric), then ROUND the numeric to 0 decimal points, then convert that to datetime.

convert(datetime,round(convert(float,orderdate,101),0) ,101)

No, there is no other way than

def dictMinus(dct, val):
   copy = dct.copy()
   del copy[val]
   return copy

However, often creating copies of only slightly altered dictionaries is probably not a good idea because it will result in comparatively large memory demands. It is usually better to log the old dictionary(if even necessary) and then modify it.

It looks like you are trying to use (almost) straight up C code here. Go has a few differences.

• First off, you can't initialize arrays and slices as const. The term const has a different meaning in Go, as it does in C. The list should be defined as var instead.
• Secondly, as a style rule, Go prefers basenameOpts as opposed to basename_opts.
• There is no char type in Go. You probably want byte (or rune if you intend to allow unicode codepoints).
• The declaration of the list must have the assignment operator in this case. E.g.: var x = foo.
• Go's parser requires that each element in a list declaration ends with a comma. This includes the last element. The reason for this is because Go automatically inserts semi-colons where needed. And this requires somewhat stricter syntax in order to work.

For example:

type opt struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}

var basenameOpts = []opt { 
    opt {
        shortnm: 'a', 
        longnm: "multiple", 
        needArg: false, 
        help: "Usage for a",
    },
    opt {
        shortnm: 'b', 
        longnm: "b-option", 
        needArg: false, 
        help: "Usage for b",
    },
}

An alternative is to declare the list with its type and then use an init function to fill it up. This is mostly useful if you intend to use values returned by functions in the data structure. init functions are run when the program is being initialized and are guaranteed to finish before main is executed. You can have multiple init functions in a package, or even in the same source file.

    type opt struct {
        shortnm      byte
        longnm, help string
        needArg      bool
    }

    var basenameOpts []opt

    func init() { 
        basenameOpts = []opt{
            opt {
                shortnm: 'a', 
                longnm: "multiple", 
                needArg: false, 
                help: "Usage for a",
            },
            opt {
                shortnm: 'b', 
                longnm: "b-option", 
                needArg: false, 
               help: "Usage for b",
            },
        }
    }

Since you are new to Go, I strongly recommend reading through the language specification. It is pretty short and very clearly written. It will clear a lot of these little idiosyncrasies up for you.

For streaming protocols such as TCP, you can pretty much set your buffer to any size. That said, common values that are powers of 2 such as 4096 or 8192 are recommended.

If there is more data then what your buffer, it will simply be saved in the kernel for your next call to recv.

Yes, you can keep growing your buffer. You can do a recv into the middle of the buffer starting at offset idx, you would do:

recv(socket, recv_buffer + idx, recv_buffer_size - idx, 0);

your validation should be occur before your event suppose you are going to submit your form.

anyway if you want this on onchange, so here is code.

function valid(id)
{
    var textVal=document.getElementById(id).value;
    if (!textVal.match(/\S/)) 
    {
        alert("Field is blank");
        return false;
    } 
    else 
    {
        return true;
    }
 }

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

Probably you are looking for JavaScript™ for Acrobat® API Reference.

This reference should be the most complete. But, as @Orbling said, not all PDF viewers might support all of the API.

EDIT:

It turns out there are newer versions of the reference in Acrobat SDK (thanks to @jss).

Acrobat Developer Center contains links to different versions of documentation. Current version of JavaScript reference from Acrobat DC SDK is available there too.

"You should always use GridFS for storing files larger than 16MB" - When should I use GridFS?

MongoDB BSON documents are capped at 16 MB. So if the total size of your array of files is less than that, you may store them directly in your document using the BinData data type.

Videos, images, PDFs, spreadsheets, etc. - it doesn't matter, they are all treated the same. It's up to your application to return an appropriate content type header to display them.

Check out the GridFS documentation for more details.

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Use <location> configuration tag, and <allow users="?"/> to allow anonymous only or <allow users="*"/> for all:

            <allow users="?"/>

      </system.web>
   </location>
</configuration>

The easiest way to have different configurations for different environments is to use spring profiles. See externalised configuration.

This gives you a lot of flexibility. I am using it in my projects and it is extremely helpful. In your case you would have 3 profiles: 'local', 'jenkins', and 'openshift'

You then have 3 profile specific property files: application-local.properties, application-jenkins.properties, and application-openshift.properties

There you can set the properties for the regarding environment. When you run the app you have to specify the profile to activate like this: -Dspring.profiles.active=jenkins

Edit

According to the spring doc you can set the system environment variable SPRING_PROFILES_ACTIVE to activate profiles and don't need to pass it as a parameter.

is there any way to pass active profile option for web app at run time ?

No. Spring determines the active profiles as one of the first steps, when building the application context. The active profiles are then used to decide which property files are read and which beans are instantiated. Once the application is started this cannot be changed.

For what it's worth I wrote this to truncate to word boundary without leaving punctuation or whitespace at the end of the string:

function truncateStringToWord(str, length, addEllipsis)_x000D_
{_x000D_
    if(str.length <= length)_x000D_
    {_x000D_
        // provided string already short enough_x000D_
        return(str);_x000D_
    }_x000D_
_x000D_
    // cut string down but keep 1 extra character so we can check if a non-word character exists beyond the boundary_x000D_
    str = str.substr(0, length+1);_x000D_
_x000D_
    // cut any non-whitespace characters off the end of the string_x000D_
    if (/[^\s]+$/.test(str))_x000D_
    {_x000D_
        str = str.replace(/[^\s]+$/, "");_x000D_
    }_x000D_
_x000D_
    // cut any remaining non-word characters_x000D_
    str = str.replace(/[^\w]+$/, "");_x000D_
_x000D_
    var ellipsis = addEllipsis && str.length > 0 ? '&hellip;' : '';_x000D_
_x000D_
    return(str + ellipsis);_x000D_
}_x000D_
_x000D_
var testString = "hi stack overflow, how are you? Spare";_x000D_
var i = testString.length;_x000D_
_x000D_
document.write('<strong>Without ellipsis:</strong><br>');_x000D_
_x000D_
while(i > 0)_x000D_
{_x000D_
  document.write(i+': "'+ truncateStringToWord(testString, i) +'"<br>');_x000D_
  i--;_x000D_
}_x000D_
_x000D_
document.write('<strong>With ellipsis:</strong><br>');_x000D_
_x000D_
i = testString.length;_x000D_
while(i > 0)_x000D_
{_x000D_
  document.write(i+': "'+ truncateStringToWord(testString, i, true) +'"<br>');_x000D_
  i--;_x000D_
}

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

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

Here's a demo:

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

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

You may have forgotten to define the Content-Type header. For example:

  return {
    statusCode: 200,
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ items }),
  }

Use Google Sheets instead of Excel - this feature is built in, so you can use regex right from the find and replace dialog.

To answer your question:

1. Copy the data from Excel and paste into Google Sheets
2. Use the find and replace dialog with regex
3. Copy the data from Google Sheets and paste back into Excel

Doctrine is probably your best bet. Prior to Doctrine, DB_DataObject was essentially the only other utility that was open sourced.

I was also looking for a simple multi select for my company. I wanted something simple, highly customizable and with no big dependencies others than jQuery.

I didn't found one fitting my needs so I decided to code my own.
I use it in production.

Here's some demos and documentation: loudev.com

That's the way to do that: Using OAuth 2.0 for Login.

You may use other authentication methods other then Google's as long as it supports OAuth.

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

You can use Redirect::away($url)

svn co svn://path destination

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

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

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

Take a look at this thread: http://code.google.com/p/chromium/issues/detail?id=4158

The problem is caused by javascript method "window.open(URL, windowName[, windowFeatures])". If the 3rd parameter windowFeatures is specified, then alert box doesn't work in the popup constrained window in Chrome, here is a simplified reduction:

http://go/reductions/4158/test-home-constrained.html

If the 3rd parameter windowFeatures is ignored, then alert box works in the popup in Chrome(the popup is actually opened as a new tab in Chrome), like this:

http://go/reductions/4158/test-home-newtab.html

it doesn't happen in IE7, Firefox3 or Safari3, it's a chrome specific issue.

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

The process can differ depending on where and how the video is being hosted. Knowing that can help to answer the question in more detail.

As an example; this is how you can download videos with blob links on Vimeo.

1. View the source code of the video player iframe
2. Search for mp4
3. Copy link with token query
4. Download before token expires

I'm a bit late .. but i found a simpler solution using auto-focus .. This could be useful for buttons or other when popping a dialog :

<button auto-focus ng-click="func()">ok</button>

That should be fine if you want to press the button onSpace or Enter clicks .

Although this an old post, I am sharing another working example.

"COLUMN COUNT AS WELL AS EACH COLUMN DATATYPE MUST MATCH WHEN 'UNION' OR 'UNION ALL' IS USED"

Let us take an example:

1:

In SQL if we write - SELECT 'column1', 'column2' (NOTE: remember to specify names in quotes) In a result set, it will display empty columns with two headers - column1 and column2

2: I share one simple instance I came across.

I had seven columns with few different datatypes in SQL. I.e. uniqueidentifier, datetime, nvarchar

My task was to retrieve comma separated result set with column header. So that when I export the data to CSV I have comma separated rows with first row as header and has respective column names.

SELECT CONVERT(NVARCHAR(36), 'Event ID') + ', ' + 
'Last Name' + ', ' + 
'First Name' + ', ' + 
'Middle Name' + ', ' + 
CONVERT(NVARCHAR(36), 'Document Type') + ', ' + 
'Event Type' + ', ' + 
CONVERT(VARCHAR(23), 'Last Updated', 126)

UNION ALL

SELECT CONVERT(NVARCHAR(36), inspectionid) + ', ' + 
       individuallastname + ', ' + 
       individualfirstname + ', ' + 
       individualmiddlename + ', ' +
       CONVERT(NVARCHAR(36), documenttype) + ', ' + 
       'I' + ', ' +
       CONVERT(VARCHAR(23), modifiedon, 126)
FROM Inspection

Above, columns 'inspectionid' & 'documenttype' has uniqueidentifer datatype and so applied CONVERT(NVARCHAR(36)). column 'modifiedon' is datetime and so applied CONVERT(NVARCHAR(23), 'modifiedon', 126).

Parallel to above 2nd SELECT query matched 1st SELECT query as per datatype of each column.

I would recommend using Wireshark, which has a "Follow TCP Stream" option that makes it very easy to see the full requests and responses for a particular TCP connection. If you would prefer to use the command line, you can try tcpflow, a tool dedicated to capturing and reconstructing the contents of TCP streams.

Other options would be using an HTTP debugging proxy, like Charles or Fiddler as EricLaw suggests. These have the advantage of having specific support for HTTP to make it easier to deal with various sorts of encodings, and other features like saving requests to replay them or editing requests.

You could also use a tool like Firebug (Firefox), Web Inspector (Safari, Chrome, and other WebKit-based browsers), or Opera Dragonfly, all of which provide some ability to view the request and response headers and bodies (though most of them don't allow you to see the exact byte stream, but instead how the browsers parsed the requests).

And finally, you can always construct requests by hand, using something like telnet, netcat, or socat to connect to port 80 and type the request in manually, or a tool like htty to help easily construct a request and inspect the response.

In case you have the following:

<input type="file" id="fileControl">

then just do:

$("#fileControl").val('');

to reset the file control.

1. You can't spell

The first thing to test is have you spelled the name of the package correctly? Package names are case sensitive in R.

2. You didn't look in the right repository

Next, you should check to see if the package is available. Type

setRepositories()

See also ?setRepositories.

To see which repositories R will look in for your package, and optionally select some additional ones. At the very least, you will usually want CRAN to be selected, and CRAN (extras) if you use Windows, and the Bioc* repositories if you do any [gen/prote/metabol/transcript]omics biological analyses.

To permanently change this, add a line like setRepositories(ind = c(1:6, 8)) to your Rprofile.site file.

3. The package is not in the repositories you selected

Return all the available packages using

ap <- available.packages()

See also Names of R's available packages, ?available.packages.

Since this is a large matrix, you may wish to use the data viewer to examine it. Alternatively, you can quickly check to see if the package is available by testing against the row names.

View(ap)
"foobarbaz" %in% rownames(ap)

Alternatively, the list of available packages can be seen in a browser for CRAN, CRAN (extras), Bioconductor, R-forge, RForge, and github.

Another possible warnings message you may get when interacting with CRAN mirrors is:

Warning: unable to access index for repository

Which may indicate the selected CRAN repository is currently be unavailable. You can select a different mirror with chooseCRANmirror() and try the installation again.

There are several reasons why a package may not be available.

4. You don't want a package

Perhaps you don't really want a package. It is common to be confused about the difference between a package and a library, or a package and a dataset.

A package is a standardized collection of material extending R, e.g. providing code, data, or documentation. A library is a place (directory) where R knows to find packages it can use

To see available datasets, type

data()

5. R or Bioconductor is out of date

It may have a dependency on a more recent version of R (or one of the packages that it imports/depends upon does). Look at

ap["foobarbaz", "Depends"]

and consider updating your R installation to the current version. On Windows, this is most easily done via the installr package.

library(installr)
updateR()

(Of course, you may need to install.packages("installr") first.)

Equivalently for Bioconductor packages, you may need to update your Bioconductor installation.

source("http://bioconductor.org/biocLite.R")
biocLite("BiocUpgrade")

6. The package is out of date

It may have been archived (if it is no longer maintained and no longer passes R CMD check tests).

In this case, you can load an old version of the package using install_version()

library(remotes)
install_version("foobarbaz", "0.1.2")

An alternative is to install from the github CRAN mirror.

library(remotes)
install_github("cran/foobarbaz")

7. There is no Windows/OS X/Linux binary

It may not have a Windows binary due to requiring additional software that CRAN does not have. Additionally, some packages are available only via the sources for some or all platforms. In this case, there may be a version in the CRAN (extras) repository (see setRepositories above).

If the package requires compiling code (e.g. C, C++, FORTRAN) then on Windows install Rtools or on OS X install the developer tools accompanying XCode, and install the source version of the package via:

install.packages("foobarbaz", type = "source")

# Or equivalently, for Bioconductor packages:
source("http://bioconductor.org/biocLite.R")
biocLite("foobarbaz", type = "source")

On CRAN, you can tell if you'll need special tools to build the package from source by looking at the NeedsCompilation flag in the description.

8. The package is on github/Bitbucket/Gitorious

It may have a repository on Github/Bitbucket/Gitorious. These packages require the remotes package to install.

library(remotes)
install_github("packageauthor/foobarbaz")
install_bitbucket("packageauthor/foobarbaz")
install_gitorious("packageauthor/foobarbaz")

(As with installr, you may need to install.packages("remotes") first.)

9. There is no source version of the package

Although the binary version of your package is available, the source version is not. You can turn off this check by setting

options(install.packages.check.source = "no")

as described in this SO answer by imanuelc and the Details section of ?install.packages.

10. The package is in a non-standard repository

Your package is in a non-standard repository (e.g. Rbbg). Assuming that it is reasonably compliant with CRAN standards, you can still download it using install.packages; you just have to specify the repository URL.

install.packages("Rbbg", repos = "http://r.findata.org")

RHIPE on the other hand isn't in a CRAN-like repository and has its own installation instructions.

an alterable way to run an .jar app is create an .bat cmd for it. for example, you have jre10 and jre8 installed on your pc,and jre10 is your default jre. but your jar is specified to work with jre8,following cmd will work:

"C:\Program Files\Java\jre1.8.0_181\bin\java.exe" -jar JabRef-4.3.1.jar

There's now an easy way to do this using dplyr.

dplyr::pull(aframe, a2)

The big downside of your current approach is its inefficiency with large search result sets, as you have to pull down the entire result set from the database each time, even though you only intend to display one page of results.

In order to only pull down the objects you actually need from the database, you have to use pagination on a QuerySet, not a list. If you do this, Django actually slices the QuerySet before the query is executed, so the SQL query will use OFFSET and LIMIT to only get the records you will actually display. But you can't do this unless you can cram your search into a single query somehow.

Given that all three of your models have title and body fields, why not use model inheritance? Just have all three models inherit from a common ancestor that has title and body, and perform the search as a single query on the ancestor model.

The root directory of a web application has a special significance and certain content can be present on in that folder. It can have a special file called as “Global.asax”. ASP.Net framework uses the content in the global.asax and creates a class at runtime which is inherited from HttpApplication. During the lifetime of an application, ASP.NET maintains a pool of Global.asax derived HttpApplication instances. When an application receives an http request, the ASP.Net page framework assigns one of these instances to process that request. That instance is responsible for managing the entire lifetime of the request it is assigned to and the instance can only be reused after the request has been completed when it is returned to the pool. The instance members in Global.asax cannot be used for sharing data across requests but static member can be. Global.asax can contain the event handlers of HttpApplication object and some other important methods which would execute at various points in a web application

If you'd checked the results of stream.Read, you'd have seen that it hadn't read anything - because you haven't rewound the stream. (You could do this with stream.Position = 0;.) However, it's easier to just call ToArray:

settingsString = LocalEncoding.GetString(stream.ToArray());

(You'll need to change the type of stream from Stream to MemoryStream, but that's okay as it's in the same method where you create it.)

Alternatively - and even more simply - just use StringWriter instead of StreamWriter. You'll need to create a subclass if you want to use UTF-8 instead of UTF-16, but that's pretty easy. See this answer for an example.

I'm concerned by the way you're just catching Exception and assuming that it means something harmless, by the way - without even logging anything. Note that using statements are generally cleaner than writing explicit finally blocks.

This should work

SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;

I have assumed the ** were just for highlighting?

If it is not necessary turn off 'Enable 32-bit Applications' from your respective application pool of your website.

This worked for me on my local machine

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

object[] newarray = new object[oldarray.Length-1];

for(int x=0; x < array.Length; x++)
{
  if(!(array[x] == value_of_array_to_delete))
  // if(!(x == array_index_to_delete))
   {
     newarray[x] = oldarray[x];
   }
}

There is no way to downsize an array after it is created, but you can copy the contents to another array of a lesser size.

STL has a max_elements function. Here is an example: http://www.cplusplus.com/reference/algorithm/max_element/

Well from its description it appears it tries to make the user agent's default style consistent across all browsers rather than stripping away all the default styling as a reset would.

Preserves useful defaults, unlike many CSS resets.

It's actually quite simple. If you declare a variable as static in the scope of a function, its value is preserved between successive calls to that function. So:

int myFun()
{
static int i=5;
i++;
return i;
}
int main()
{
printf("%d", myFun());
printf("%d", myFun());
printf("%d", myFun());
}

will show 678 instead of 666, because it remembers the incremented value.

As for the static members, they preserve their value across instances of the class. So the following code:

struct A
{
static int a;
};
int main()
{
A first;
A second;
first.a = 3;
second.a = 4;
printf("%d", first.a);
}

will print 4, because first.a and second.a are essentially the same variable. As for the initialization, see this question.

if you are windows user, then it's in C:\Users\your_user_name\Envs. You can delete it from there.

Also try in command prompt rmvirtualenv environment name.

I tried with command prompt so it said deleted but it was still existed. So i manually delete it.

You need to add a TraceListener to see them appear on the Console.

TextWriterTraceListener writer = new TextWriterTraceListener(System.Console.Out);
Debug.Listeners.Add(writer);

They also appear in the Visual Studio Output window when in Debug mode.

Adding following to ansible config worked while using ansible ad-hoc commands:

# ssh arguments to use
ssh_args = -o StrictHostKeyChecking=no

config file = /etc/ansible/ansible.cfg

You can use the usual Python package structure to divide your App into multiple modules, see the Flask docs.

However,

Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications.

You can create a sub-component of your app as a Blueprint in a separate file:

simple_page = Blueprint('simple_page', __name__, template_folder='templates')
@simple_page.route('/<page>')
def show(page):
    # stuff

And then use it in the main part:

from yourapplication.simple_page import simple_page

app = Flask(__name__)
app.register_blueprint(simple_page)

Blueprints can also bundle specific resources: templates or static files. Please refer to the Flask docs for all the details.

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Trying using :

imageview.setFitToScreen(true);
imageview.setScaleType(ScaleType.FIT_CENTER);

This will fit your imageview to the screen with the correct ratio.

use isinstance(v, type_name) or type(v) is type_name or type(v) == type_name,

where type_name can be one of the following:

• None
• bool
• int
• float
• complex
• str
• list
• tuple
• set
• dict

and, of course,

• custom types (classes)

As you have mentioned it doesn't change anything.

First, you should redirect both standard input and standard error from the crontab execution like below:

*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py > /tmp/listener.log 2>&1

Then you can view the file /tmp/listener.log to see if the script executed as you expected.

Second, I guess what you mean by change anything is by watching the files created by your program:

f = file('counter', 'r+w')
json_file = file('json_file_create_server.json', 'r+w')

The crontab job above won't create these file in directory /home/souza/Documets/Listener, as the cron job is not executed in this directory, and you use relative path in the program. So to create this file in directory /home/souza/Documets/Listener, the following cron job will do the trick:

*/2 * * * * cd /home/souza/Documets/Listener && /usr/bin/python listener.py > /tmp/listener.log 2>&1

Change to the working directory and execute the script from there, and then you can view the files created in place.

It obtains a reference to the class object with the FQCN (fully qualified class name) oracle.jdbc.driver.OracleDriver.

It doesn't "do" anything in terms of connecting to a database, aside from ensure that the specified class is loaded by the current classloader. There is no fundamental difference between writing

Class<?> driverClass = Class.forName("oracle.jdbc.driver.OracleDriver");
// and
Class<?> stringClass = Class.forName("java.lang.String");

Class.forName("com.example.some.jdbc.driver") calls show up in legacy code that uses JDBC because that is the legacy way of loading a JDBC driver.

From The Java Tutorial:

In previous versions of JDBC, to obtain a connection, you first had to initialize your JDBC driver by calling the method Class.forName. This methods required an object of type java.sql.Driver. Each JDBC driver contains one or more classes that implements the interface java.sql.Driver.
...
Any JDBC 4.0 drivers that are found in your class path are automatically loaded. (However, you must manually load any drivers prior to JDBC 4.0 with the method Class.forName.)

Further reading _{^{(read: questions this is a dup of)}}

• What purpose does Class.forName() serve if you don't use the return value?
• How does Class.forName() work?
• What does 'Class.forName("org.sqlite.JDBC");' do?
• What is the purpose of 'Class.forName("MY_JDBC_DRIVER")'?
• Loading JDBC driver

Another reason for "lost update" can be the next:

• If the static getDerivedStateFromProps is defined then it is rerun in every update process according to official documentation https://reactjs.org/docs/react-component.html#updating.
• so if that state value comes from props at the beginning it is overwrite in every update.

If it is the problem then U can avoid setting the state during update, you should check the state parameter value like this

static getDerivedStateFromProps(props: TimeCorrectionProps, state: TimeCorrectionState): TimeCorrectionState {
   return state ? state : {disable: false, timeCorrection: props.timeCorrection};
}

Another solution is add a initialized property to state, and set it up in the first time (if the state is initialized to non null value.)

If you add: 

Settings.Secure.getString(context.contentResolver,
    Settings.Secure.ANDROID_ID)

Android Lint will give you the following warning:

Using getString to get device identifiers is not recommended. Inspection info: Using these device identifiers is not recommended other than for high value fraud prevention and advanced telephony use-cases. For advertising use-cases, use AdvertisingIdClient$Info#getId and for analytics, use InstanceId#getId.

So, you should avoid using this.

As mentioned in Android Developer documentation :

1: Avoid using hardware identifiers.

In most use cases, you can avoid using hardware identifiers, such as SSAID (Android ID) and IMEI, without limiting required functionality.

2: Only use an Advertising ID for user profiling or ads use cases.

When using an Advertising ID, always respect users' selections regarding ad tracking. Also, ensure that the identifier cannot be connected to personally identifiable information (PII), and avoid bridging Advertising ID resets.

3: Use an Instance ID or a privately stored GUID whenever possible for all other use cases, except for payment fraud prevention and telephony.

For the vast majority of non-ads use cases, an Instance ID or GUID should be sufficient.

4: Use APIs that are appropriate for your use case to minimize privacy risk.

Use the DRM API for high-value content protection and the SafetyNet APIs for abuse protection. The SafetyNet APIs are the easiest way to determine whether a device is genuine without incurring privacy risk.

I created a project to easily initiate a project skeleton from scratch. https://github.com/MacHu-GWU/pygitrepo-project.

And you can create a test project, let's say, learn_creating_py_package.

You can learn what component you should have for different purpose like:

• create virtualenv
• install itself
• run unittest
• run code coverage
• build document
• deploy document
• run unittest in different python version
• deploy to PYPI

The advantage of using pygitrepo is that those tedious are automatically created itself and adapt your package_name, project_name, github_account, document host service, windows or macos or linux.

It is a good place to learn develop a python project like a pro.

Hope this could help.

Thank you.

From your post I gather that you want to compare dates, not arrays. If this is the case, then use the appropriate object: a datetime object.

Please check the documentation for the datetime module. Dates are a tough cookie. Use reliable algorithms.

Try following steps:

1. Type ipconfig (or ifconfig on Linux) at command prompt. This will give you the IP address of your own machine. For example, your machine's IP address is 192.168.1.6. So your broadcast IP address is 192.168.1.255.
2. Ping your broadcast IP address ping 192.168.1.255 (may require -b on Linux)
3. Now type arp -a. You will get the list of all IP addresses on your segment.

Your change should work. However, there are potentially few php.ini configuration files with the 'xampp' stack. Try to identify whether or not there's an 'apache' specific php.ini. One potential location is:

C:\xampp\apache\bin\php.ini

This problem happened because either u install new version of jdk so you have both 32bit version and 64bit

how to solve the problem is just go open computer & go to c then you will see

after that you probably use 32 bit so just chose C:\Program Files and there you will find folder called java

in it

so you have many different version of jdk so easily chose jre7 and to to bin and you will find javaw.exe in it like

now only just take that path copy and go to start type eclipse.ini you will see text file just open it and before -vmargs

write -vm enter path like photo

now just open eclipse again and have fun :D

If you want to retain the last one of the duplicates you could use

 tac a.csv | sort -u -t, -r -k1,1 |tac

Which was my requirement

here

tac will reverse the file line by line
