Programs & Examples On #Powergui

You're almost correct, just misplaced a few quotes. Wrapping the whole thing in regular quotes will literally give you the string #demo + {this.state.id} - you need to indicate which are variables and which are string literals. Since anything inside {} is an inline JSX expression, you can do:

href={"#demo" + this.state.id}

This will use the string literal #demo and concatenate it to the value of this.state.id. This can then be applied to all strings. Consider this:

var text = "world";

And this:

{"Hello " + text + " Andrew"}

This will yield:

Hello world Andrew 

You can also use ES6 string interpolation/template literals with ` (backticks) and ${expr} (interpolated expression), which is closer to what you seem to be trying to do:

href={`#demo${this.state.id}`}

This will basically substitute the value of this.state.id, concatenating it to #demo. It is equivalent to doing: "#demo" + this.state.id.

You can also use the command line, Change directory where your folder is located then type the following :

     git init
     git add <folder1> <folder2> <etc.>
     git commit -m "Your message about the commit"
     git remote add origin https://github.com/yourUsername/yourRepository.git
     git push -u origin master
     git push origin master  

I actually found the right command to use.. its called timeout: http://www.ss64.com/nt/timeout.html

And to consume the hidden ID input back on your Edit action method:

[HttpPost]
public ActionResult Edit(FormCollection collection)
{
    ViewModel.ID = Convert.ToInt32(collection["ID"]);
}

It looks like you're using the wrong tool there. Grep isn't that sophisticated, I think you want to step up to awk as the tool for the job:

awk '/blah/ { getline; print $0 }' logfile

If you get any problems let me know, I think its well worth learning a bit of awk, its a great tool :)

p.s. This example doesn't win a 'useless use of cat award' ;) http://porkmail.org/era/unix/award.html

I've needed to do this myself a few times - especially when installing on another machine.

Common questions will give you the location of your folder

Visual Studio Code looks for extensions under your extensions folder .vscode/extensions. Depending on your platform it is located:

Windows %USERPROFILE%\.vscode\extensions
Mac ~/.vscode/extensions
Linux ~/.vscode/extensions

That should show you a list of the extensions.

I've also had success using Visual Studio Code Settings Sync Extension to sync settings to GitHub gist.

In the latest release of Visual Studio Code (May 2016), it is now possible to list the installed extensions on the command line:

code --list-extensions

If the author has a GitHub account, just click the author's username from anywhere in the commit history, and the commits you can see will be filtered down to those by that author:

You can also click the 'n commits' link below their name on the repo's "contributors" page:

Alternatively, you can directly append ?author=<theusername> or ?author=<emailaddress> to the URL. For example, https://github.com/jquery/jquery/commits/master?author=dmethvin or https://github.com/jquery/jquery/commits/[email protected] both give me:

For authors without a GitHub account, only filtering by email address will work, and you will need to manually add ?author=<emailaddress> to the URL - the author's name will not be clickable from the commits list.

You can also get the list of commits by a particular author from the command line using

git log --author=[your git name]

Example:

git log --author=Prem

Solution is :-

1. Restart
2. Go to advanced menu and then click on 'e'(edit the boot parameters)
3. Go down to the line which starts with linux and press End
4. Press space
5. Add the following at the end -> kernel.panic=1
6. Press F10 to restart

This basically forces your PC to restart because by default it does not restart after a kernel panic.

I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)

For example:

$('.btnName').click(function() {
 top.$('#panel').toggle(function() {
   $(this).animate({ 
     // style change
   }, 500);
   },
   function() {
   $(this).animate({ 
     // style change back
   }, 500);
 });

There are actually two place where where mac os x serves website by default:

~/Sites --> http://localhost/~user/

TFS users: If you are using source control that requires you to warn it before your rename files/folders then look at this answer instead which covers the extra steps required.

To rename a project's folder, file (.*proj) and display name in Visual Studio:

• Close the solution.
• Rename the folder(s) outside Visual Studio. (Rename in TFS if using source control)
• Open the solution, ignoring the warnings (answer "no" if asked to load a project from source control).
• Go through all the unavailable projects and...
  • Open the properties window for the project (highlight the project and press Alt+Enter or F4, or right-click > properties).
  • Set the property 'File Path' to the new location.
    • If the property is not editable (as in Visual Studio 2012), then open the .sln file directly in another editor such as Notepad++ and update the paths there instead. (You may need to check-out the solution first in TFS, etc.)
  • Reload the project - right-click > reload project.
  • Change the display name of the project, by highlighting it and pressing F2, or right-click > rename.

Note: Other suggested solutions that involve removing and then re-adding the project to the solution will break project references.

If you perform these steps then you might also consider renaming the following to match:

1. Assembly
2. Default/Root Namespace
3. Namespace of existing files (use the refactor tools in Visual Studio or ReSharper's inconsistent namespaces tool)

Also consider modifying the values of the following assembly attributes:

1. AssemblyProductAttribute
2. AssemblyDescriptionAttribute
3. AssemblyTitleAttribute

This will help you...

DataTable dt = new DataTable();         
dt.DefaultView.Sort = "Column_name desc";
dt = dt.DefaultView.ToTable();

1. Open your favorite text editor
2. Create a new file named whatever.h
3. Put your function prototypes in it

DONE.

Example whatever.h

#ifndef WHATEVER_H_INCLUDED
#define WHATEVER_H_INCLUDED
int f(int a);
#endif

Note: include guards (preprocessor commands) added thanks to luke. They avoid including the same header file twice in the same compilation. Another possibility (also mentioned on the comments) is to add #pragma once but it is not guaranteed to be supported on every compiler.

Example whatever.c

#include "whatever.h"

int f(int a) { return a + 1; }

And then you can include "whatever.h" into any other .c file, and link it with whatever.c's object file.

Like this:

sample.c

#include "whatever.h"

int main(int argc, char **argv)
{
    printf("%d\n", f(2)); /* prints 3 */
    return 0;
}

To compile it (if you use GCC):

$ gcc -c whatever.c -o whatever.o
$ gcc -c sample.c -o sample.o

To link the files to create an executable file:

$ gcc sample.o whatever.o -o sample

You can test sample:

$ ./sample
3
$

Use profiler module. It gives a very detailed profile.

import profile
profile.run('main()')

it outputs something like:

        1    0.000    0.000    0.047    0.047 profile:0(main())
        1    0.000    0.000    0.000    0.000 two_sum.py:2(twoSum)

I've found it very informative.

Here is a different view or solution for the original problem. Here I show that we have an option to write a code that will process only a valid subset of values with an option to detect and handle caseses when the exception was thrown.

    @Test
    public void getClasses() {

        String[] classNames = {"java.lang.Object", "java.lang.Integer", "java.lang.Foo"};
        List<Class> classes =
                Stream.of(classNames)
                        .map(className -> {
                            try {
                                return Class.forName(className);
                            } catch (ClassNotFoundException e) {
                                // log the error
                                return null;
                            }
                        })
                        .filter(c -> c != null)
                        .collect(Collectors.toList());

        if (classes.size() != classNames.length) {
            // add your error handling here if needed or process only the resulting list
            System.out.println("Did not process all class names");
        }

        classes.forEach(System.out::println);
    }

Just wanted to focus on the last part of the question; How source map files are created? by listing the build tools I know that can create source maps.

1. Grunt: using plugin grunt-contrib-uglify
2. Gulp: using plugin gulp-uglify
3. Google closure: using parameter --create_source_map

For me, an issue where json_encode would return null encoding of an entity was because my jsonSerialize implementation fetched entire objects for related entities; I solved the issue by making sure that I fetched the ID of the related/associated entity and called ->toArray() when there were more than one entity associated with the object to be json serialized. Note, I'm speaking about cases where one implements JsonSerializable on entities.

I just got that problem when converting from % formatting to .format().

Previous code:

"SET !TIMEOUT_STEP %{USER_TIMEOUT_STEP}d" % {'USER_TIMEOUT_STEP' = 3}

Problematic syntax:

"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format('USER_TIMEOUT_STEP' = 3)

The problem is that format is a function that needs parameters. They cannot be strings. That is one of worst python error messages I've ever seen.

Corrected code:

"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format(USER_TIMEOUT_STEP = 3)

You can specify both max post size and max file size limit in php.ini

post_max_size = 64M
upload_max_filesize = 64M

I wrote the following procedure for concatenation of several array:

  static public byte[] concat(byte[]... bufs) {
    if (bufs.length == 0)
        return null;
    if (bufs.length == 1)
        return bufs[0];
    for (int i = 0; i < bufs.length - 1; i++) {
        byte[] res = Arrays.copyOf(bufs[i], bufs[i].length+bufs[i + 1].length);
        System.arraycopy(bufs[i + 1], 0, res, bufs[i].length, bufs[i + 1].length);
        bufs[i + 1] = res;
    }
    return bufs[bufs.length - 1];
}

It uses Arrays.copyOf

You simply select dates that are higher than the current time minus 1 day.

SELECT * FROM news WHERE date >= now() - INTERVAL 1 DAY;

This is an answer to @craq :

I just compiled the file from C source and set it to be executable with chmod. There were no warning or error messages from gcc.

I'm a bit surprised that you had to 'set it to executable' -- my gcc always sets the executable flag itself. This suggests to me that gcc didn't expect this to be the final executable file, or that it didn't expect it to be executable on this system.

Now I've tried to just create the object file, like so:

$ gcc -c -o hello hello.c
$ chmod +x hello

(hello.c is a typical "Hello World" program.) But my error message is a bit different:

$ ./hello
bash: ./hello: cannot execute binary file: Exec format error`

On the other hand, this way, the output of the file command is identical to yours:

$ file hello
hello: ELF 64-bit LSB  relocatable, x86-64, version 1 (SYSV), not stripped

Whereas if I compile correctly, its output is much longer.

$ gcc -o hello hello.c
$ file hello
hello: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=131bb123a67dd3089d23d5aaaa65a79c4c6a0ef7, not stripped

What I am saying is: I suspect it has something to do with the way you compile and link your code. Maybe you can shed some light on how you do that?

You can use this and then you can add just a class form from bootstrap. ^{(does not matter which version)}

<div class="form-group">
 <label >Begin voorverkoop periode</label>
 <input type="date" name="bday" max="3000-12-31" 
        min="1000-01-01" class="form-control">
</div>
<div class="form-group">
 <label >Einde voorverkoop periode</label>
 <input type="date" name="bday" min="1000-01-01"
        max="3000-12-31" class="form-control">
</div>

Use the getTime method to get the time in total milliseconds since 1970-01-01, and subtract those:

var time = new Date().getTime() - new Date("2013-02-20T12:01:04.753Z").getTime();

if you want get all values from form in simple array you may be do something like this.

function getValues(form) {
    var listvalues = new Array();
    var datastring = $("#" + form).serializeArray();
    var data = "{";
    for (var x = 0; x < datastring.length; x++) {
        if (data == "{") {
            data += "\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
        else {
            data += ",\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
    }
    data += "}";
    data = JSON.parse(data);
    listvalues.push(data);
    return listvalues;
};

We use maven2 in all our projects and it speeds up development tenfold (combined with a nice continuous integration platform).

The only feature of maven2 that has caused us a lot of headaches in the past is the transitive dependency mechanism. In a Utopian world it would be the end-all solution to all dependency issues but in practice it tends to send you straight to dependency hell.

Our main problem came from the fact that various components in the default maven2 repository depend on different versions of the same library (i.e component1 and component2 both require a logging framework but component1 requires v1 and component2 requires v2).

To solve this we simply have our own local repository containing all the libraries we need. This allows us to ensure that all libraries we use that have their own dependencies depend on the same versions of other libraries.

If your textbox is a Required field and have some regex pattern to match and has minlength and maxlength

TestBox code

<input type="text" name="myfieldname" ng-pattern="/^[ A-Za-z0-9_@./#&+-]*$/" ng-minlength="3" ng-maxlength="50" class="classname" ng-model="model.myfieldmodel">

Ng-Class to Add

ng-class="{ 'err' :  myform.myfieldname.$invalid || (myform.myfieldname.$touched && !model.myfieldmodel.length) }"

It's good practise to extend from a baseController and implement some base functions implement a function to check if the user instance is null like this if the user form the Userinterface then there is no user logged in

/**

*/
class BaseController extends AbstractController
{

    /**
     * @return User

     */
    protected function getUser(): ?User
    {
        return parent::getUser();
    }

    /**
     * @return bool
     */
    protected function isUserLoggedIn(): bool
    {
        return $this->getUser() instanceof User;
    }
}

I was using a duplicate Foreign Key Name.

Renaming the FK name solved my problem.

Clarification:

Both tables had a constraint called PK1, FK1, etc. Renaming them/making the names unique solved the problem.

XMLBeans works great if you have a schema for your XML. It creates Java objects for the schema and creates easy to use parse methods.

Couldn't you just pass the a name attribute and wrap it in a form?

<form id="form" action="do_stuff.php" method="post">
    <select id="select_catalog" name="select_catalog_query">
    <?php <<<INSERT THE SELECT OPTION LOOP>>> ?>

Sounds like you really want a Dictionary<int, string> or possibly a switch statement...

You can do it with the conditional operator though:

userType = user.Type == 0 ? "Admin"
         : user.Type == 1 ? "User"
         : user.Type == 2 ? "Employee"
         : "The default you didn't specify";

While you could put that in one line, I'd strongly urge you not to.

I would normally only do this for different conditions though - not just several different possible values, which is better handled in a map.

If its in a landscape then you will be needing more width and less height! That's just what all websites have.

Lets go with a basic first then the rest!

The basic CSS:

By CSS you can do this,

#body {
width: 100%;
height: 100%;
}

Here you are using a div with id body, as:

<body>
  <div id="body>
    all the text would go here!
  </div>
</body>

Then you can have a web page with 100% height and width.

What if he tries to resize the window?

The issues pops up, what if he tries to resize the window? Then all the elements inside #body would try to mess up the UI. For that you can write this:

#body {
height: 100%;
width: 100%;
}

And just add min-height max-height min-width and max-width.

This way, the page element would stay at the place they were at the page load.

Using JavaScript:

Using JavaScript, you can control the UI, use jQuery as:

$('#body').css('min-height', '100%');

And all other remaining CSS properties, and JS will take care of the User Interface when the user is trying to resize the window.

How to not add scroll to the web page:

If you are not trying to add a scroll, then you can use this JS

$('#body').css('min-height', screen.height); // or anyother like window.height

This way, the document will get a new height whenever the user would load the page.

Second option is better, because when users would have different screen resolutions they would want a CSS or Style sheet created for their own screen. Not for others!

Tip: So try using JS to find current Screen size and edit the page! :)

I usually lose track of all of my -20001-type error codes, so I try to consolidate all my application errors into a nice package like such:

SET SERVEROUTPUT ON

CREATE OR REPLACE PACKAGE errors AS
  invalid_foo_err EXCEPTION;
  invalid_foo_num NUMBER := -20123;
  invalid_foo_msg VARCHAR2(32767) := 'Invalid Foo!';
  PRAGMA EXCEPTION_INIT(invalid_foo_err, -20123);  -- can't use var >:O

  illegal_bar_err EXCEPTION;
  illegal_bar_num NUMBER := -20156;
  illegal_bar_msg VARCHAR2(32767) := 'Illegal Bar!';
  PRAGMA EXCEPTION_INIT(illegal_bar_err, -20156);  -- can't use var >:O

  PROCEDURE raise_err(p_err NUMBER, p_msg VARCHAR2 DEFAULT NULL);
END;
/

CREATE OR REPLACE PACKAGE BODY errors AS
  unknown_err EXCEPTION;
  unknown_num NUMBER := -20001;
  unknown_msg VARCHAR2(32767) := 'Unknown Error Specified!';

  PROCEDURE raise_err(p_err NUMBER, p_msg VARCHAR2 DEFAULT NULL) AS
    v_msg VARCHAR2(32767);
  BEGIN
    IF p_err = unknown_num THEN
      v_msg := unknown_msg;
    ELSIF p_err = invalid_foo_num THEN
      v_msg := invalid_foo_msg;
    ELSIF p_err = illegal_bar_num THEN
      v_msg := illegal_bar_msg;
    ELSE
      raise_err(unknown_num, 'USR' || p_err || ': ' || p_msg);
    END IF;

    IF p_msg IS NOT NULL THEN
      v_msg := v_msg || ' - '||p_msg;
    END IF;

    RAISE_APPLICATION_ERROR(p_err, v_msg);
  END;
END;
/

Then call errors.raise_err(errors.invalid_foo_num, 'optional extra text') to use it, like such:

BEGIN
  BEGIN
    errors.raise_err(errors.invalid_foo_num, 'Insufficient Foo-age!');
  EXCEPTION
    WHEN errors.invalid_foo_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(errors.illegal_bar_num, 'Insufficient Bar-age!');
  EXCEPTION
    WHEN errors.illegal_bar_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(-10000, 'This Doesn''t Exist!!');
  EXCEPTION
    WHEN OTHERS THEN
      dbms_output.put_line(SQLERRM);
  END;
END;
/

produces this output:

ORA-20123: Invalid Foo! - Insufficient Foo-age!
ORA-20156: Illegal Bar! - Insufficient Bar-age!
ORA-20001: Unknown Error Specified! - USR-10000: This Doesn't Exist!!

• Declare: SET @a = 1;

• Usage: INSERT INTO `t` (`c`) VALUES (@a);

There are several options.

The easiest is likely the exec plugin.

You can also generate a jar containing all the dependencies using the assembly plugin.

Lastly, you can generate a file with the classpath in it using the dependency:classpath goal.

In my case, I used lnmp to install php with version 5.4.45. But maybe because I installed php5-dev after lnmp (which I guess is not necessary if you installed lnmp), my phpize and php-config both point to older version tools than php.
I solved this by change the soft link of /etc/alternatives/phpize and /etc/alternatives/php-config to /usr/local/php/bin/phpize and /usr/local/php/bin/php-config.
Hopes this is helpful.

I have edited the "Best answer" code, though I found a useful thing that was missing. This is will also track the ip of a user if they are using a Proxy or simply if the server has nginx installed as a proxy reverser.

I added this code to his script at the top of the function:

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

Afther that I edited his code.

Find the line that says the following:

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

and replace it with this:

$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $adresseip. $vst_id;

This will work.

Here is the full code if anything happens:

<?php

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

Haven't tested this on the Sql script yet.

Maybe something like this...

try

    // ...
}
catch (WebException ex)
{
    if (ex.Status == WebExceptionStatus.ProtocolError)
    {
        var response = ex.Response as HttpWebResponse;
        if (response != null)
        {
            Console.WriteLine("HTTP Status Code: " + (int)response.StatusCode);
        }
        else
        {
            // no http status code available
        }
    }
    else
    {
        // no http status code available

Create a class which extends HttpServlet and put @WebServlet annotation on it containing the desired URL the servlet should listen on.

@WebServlet("/yourServletURL")
public class YourServlet extends HttpServlet {}

And just let <form action> point to this URL. I would also recommend to use POST method for non-idempotent requests. You should make sure that you have specified the name attribute of the HTML form input fields (<input>, <select>, <textarea> and <button>). This represents the HTTP request parameter name. Finally, you also need to make sure that the input fields of interest are enclosed inside the desired form and thus not outside.

Here are some examples of various HTML form input fields:

<form action="${pageContext.request.contextPath}/yourServletURL" method="post">
    <p>Normal text field.        
    <input type="text" name="name" /></p>

    <p>Secret text field.        
    <input type="password" name="pass" /></p>

    <p>Single-selection radiobuttons.        
    <input type="radio" name="gender" value="M" /> Male
    <input type="radio" name="gender" value="F" /> Female</p>

    <p>Single-selection checkbox.
    <input type="checkbox" name="agree" /> Agree?</p>

    <p>Multi-selection checkboxes.
    <input type="checkbox" name="role" value="USER" /> User
    <input type="checkbox" name="role" value="ADMIN" /> Admin</p>

    <p>Single-selection dropdown.
    <select name="countryCode">
        <option value="NL">Netherlands</option>
        <option value="US">United States</option>
    </select></p>

    <p>Multi-selection listbox.
    <select name="animalId" multiple="true" size="2">
        <option value="1">Cat</option>
        <option value="2">Dog</option>
    </select></p>

    <p>Text area.
    <textarea name="message"></textarea></p>

    <p>Submit button.
    <input type="submit" name="submit" value="submit" /></p>
</form>

Create a doPost() method in your servlet which grabs the submitted input values as request parameters keyed by the input field's name (not id!). You can use request.getParameter() to get submitted value from single-value fields and request.getParameterValues() to get submitted values from multi-value fields.

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String name = request.getParameter("name");
    String pass = request.getParameter("pass");
    String gender = request.getParameter("gender");
    boolean agree = request.getParameter("agree") != null;
    String[] roles = request.getParameterValues("role");
    String countryCode = request.getParameter("countryCode");
    String[] animalIds = request.getParameterValues("animalId");
    String message = request.getParameter("message");
    boolean submitButtonPressed = request.getParameter("submit") != null;
    // ...
}

Do if necessary some validation and finally persist it in the DB the usual JDBC/DAO way.

User user = new User(name, pass, roles);
userDAO.save(user);

The command line flags -N or --LINE-NUMBERS causes a line number to be displayed at the beginning of each line in the display.

You can also toggle line numbers without quitting less by typing -N<return>. It it possible to toggle any of less's command line options in this way.

@John Woo's answer helped me solve a similar problem. I've improved upon his answer by setting the correct ordering as well. This has worked for me:

SELECT  a.*, c.*
FROM users a 
    INNER JOIN payments c
        ON a.id = c.user_ID
    INNER JOIN (
        SELECT user_ID, MAX(date) as maxDate FROM
        (
            SELECT user_ID, date
            FROM payments
            ORDER BY date DESC
        ) d
        GROUP BY user_ID
    ) b ON c.user_ID = b.user_ID AND
           c.date = b.maxDate
WHERE a.package = 1

I'm not sure how efficient this is, though.

Here is one liner for the same,

$pic_square = $userdb[array_search($uid,array_column($userdb, 'uid'))]['pic_square'];

I came across the same error message and I have tried three ways mentioned above. I listed the results as a complementary reference to others.

1. Change the PYTHON_SPARK and PYTHON_DRIVER_SPARK value in spark-env.sh does not work for me.
2. Change the value inside python script using os.environ["PYSPARK_PYTHON"]="/usr/bin/python3.5" os.environ["PYSPARK_DRIVER_PYTHON"]="/usr/bin/python3.5" does not work for me.
3. Change the value in ~/.bashrc works like a charm~

Recently i encounter this issue and try all of the above method but none of them works for me.

Here is another Trick for to solve this error is

i just delete the eclipse configuration file and eclipse start working.. i don't know why but it works.

Maybe this helps someone else.

I believe once database rules are written accurately, it will be enough to protect your data. Moreover, there are guidelines that one can follow to structure your database accordingly. For example, making a UID node under users, and putting all under information under it. After that, you will need to implement a simple database rule as below

  "rules": {
    "users": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
      }
    }
  }
}

No other user will be able to read other users' data, moreover, domain policy will restrict requests coming from other domains. One can read more about it on Firebase Security rules

In my case, it was because my publishing profile (Publish to local IIS site) was somehow set to Release Configuration, despite the fact that the global build configuration was set to Debug. Modified the publishing profile to Debug configuration solved the issue for me.

You could also use Format$(Now(), "Short Date") or whatever date format you want. Be aware, this function will return the Date as a string, so using Date() is a better approach.

To prevent JUnit from instantiating your test base class just make it

public abstract class MyTestBaseClass { ... whatever... }

(@Ignore reports it as ignored which I reserve for temporarily ignored tests.)

There seems to be a really easy solution when dealing with data type issues.

Basically, at the end of Excel connection string, add ;IMEX=1;"

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\YOURSERVER\shared\Client Projects\FOLDER\Data\FILE.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";

This will resolve data type issues such as columns where values are mixed with text and numbers.

To get to connection property, right click on Excel connection manager below control flow and hit properties. It'll be to the right under solution explorer. Hope that helps.

... Or instead of treating the commas as garbage to be filtered out, we could treat the overall string as a localized formatting of the float, and use the localization services:

from locale import atof, setlocale, LC_NUMERIC
setlocale(LC_NUMERIC, '') # set to your default locale; for me this is
# 'English_Canada.1252'. Or you could explicitly specify a locale in which floats
# are formatted the way that you describe, if that's not how your locale works :)
atof('123,456') # 123456.0
# To demonstrate, let's explicitly try a locale in which the comma is a
# decimal point:
setlocale(LC_NUMERIC, 'French_Canada.1252')
atof('123,456') # 123.456

Simple example of how to use it

 <?php  
     if(!isset($_POST) || empty($_POST)) { 
     ?> 
        <form name="form1" method="post" action=""> 
          <input type="text" name="textfield"><br /> 
          <input type="submit" name="Submit" value="submit"> 
        </form> 
   <?php  
        } else { 
        $example = file_get_contents("php://input");
        echo $example;  }  
   ?>

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

When doing;

a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')

...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

Your other example though;

a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

should work well if you just have the permission on a.txt. You may want to use a raw (r-prefixed) string though, to make sure your path does not contain any escape characters like \n that will be translated to special characters.

a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

For those looking for an inline example, here is one:

<audio controls style="width: 200px;">
   <source src="http://somewhere.mp3" type="audio/mpeg">
</audio>

It doesn't seem to respect a "height" setting, at least not awesomely. But you can always "customize" the controls but creating your own controls (instead of using the built-in ones) or using somebody's widget that similarly creates its own :)

There's a lot of buggy code here and regex solutions are very slow. I found a solution that works up to 20x faster than the regex counterpart and is elegantly simple:

    /*
    *   @param      string      parameter to return the value of.
    *   @return     string      value of chosen parameter, if found.
    */
    function get_param(return_this)
    {
        return_this = return_this.replace(/\?/ig, "").replace(/=/ig, ""); // Globally replace illegal chars.

        var url = window.location.href;                                   // Get the URL.
        var parameters = url.substring(url.indexOf("?") + 1).split("&");  // Split by "param=value".
        var params = [];                                                  // Array to store individual values.

        for(var i = 0; i < parameters.length; i++)
            if(parameters[i].search(return_this + "=") != -1)
                return parameters[i].substring(parameters[i].indexOf("=") + 1).split("+");

        return "Parameter not found";
    }

console.log(get_param("parameterName"));

Regex is not the be-all and end-all solution, for this type of problem simple string manipulation can work a huge amount more efficiently. Code source.

All md- prefixes are now mat- prefixes as of time of writing this!

Put this in your html head:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Import in our module:

import { MatIconModule } from '@angular/material';

Use in your code:

<mat-icon>face</mat-icon>

Here is the latest documentation:

https://material.angular.io/components/icon/overview

You can try the following code snippet

httpResponseMessage.Content.Headers.Add("Content-Type", "application/octet-stream");

Hope it will work for you.

In my case, it was because I was only catching specific types of exceptions:

try
  {
    get-item -Force -LiteralPath $Path -ErrorAction Stop

    #if file exists
    if ($Path -like '\\*') {$fileType = 'n'}  #Network
    elseif ($Path -like '?:\*') {$fileType = 'l'} #Local
    else {$fileType = 'u'} #Unknown File Type

  }
catch [System.UnauthorizedAccessException] {$fileType = 'i'} #Inaccessible
catch [System.Management.Automation.ItemNotFoundException]{$fileType = 'x'} #Doesn't Exist

Added these to handle additional the exception causing the terminating error, as well as unexpected exceptions

catch [System.Management.Automation.DriveNotFoundException]{$fileType = 'x'} #Doesn't Exist
catch {$fileType='u'} #Unknown

For MySql:

UPDATE table1 JOIN table2 
    ON table1.id = table2.id
SET table1.name = table2.name,
    table1.`desc` = table2.`desc`

For Sql Server:

UPDATE   table1
SET table1.name = table2.name,
    table1.[desc] = table2.[desc]
FROM table1 JOIN table2 
   ON table1.id = table2.id

If you are using Visual Studio 2017, 2019, you can:

1. open the main .gitignore (update or remove anothers .gitignore files in others projects in the solution)
2. paste the below code:

[core]
 autocrlf = false
[filter "lfs"]
 required = true
 clean = git-lfs clean -- %f
 smudge = git-lfs smudge -- %f
 process = git-lfs filter-process

If you want to keep your forEach syntax, this is a way to keep it efficient (although not as good as a regular for loop). Check immediately for a variable that knows if you want to break out of the loop.

This example uses a anonymous function for creating a function scope around the forEach which you need to store the done information.

(function(){_x000D_
    var element = document.getElementById('printed-result');_x000D_
    var done = false;_x000D_
    [1,2,3,4].forEach(function(item){_x000D_
        if(done){ return; }_x000D_
        var text = document.createTextNode(item);_x000D_
        element.appendChild(text);_x000D_
        if (item === 2){_x000D_
          done = true;_x000D_
          return;_x000D_
        }_x000D_
    });_x000D_
})();

<div id="printed-result"></div>

My two cents.

It's hard to infer what you're looking for from the question, but my best guess is as follows.

If we assume you have a DataFrame where some column is 'Category' and contains integers (or otherwise unique identifiers) for categories, then we can do the following.

Call the DataFrame dfrm, and assume that for each row, dfrm['Category'] is some value in the set of integers from 1 to N. Then,

for elem in dfrm['Category'].unique():
    dfrm[str(elem)] = dfrm['Category'] == elem

Now there will be a new indicator column for each category that is True/False depending on whether the data in that row are in that category.

If you want to control the category names, you could make a dictionary, such as

cat_names = {1:'Some_Treatment', 2:'Full_Treatment', 3:'Control'}
for elem in dfrm['Category'].unique():
    dfrm[cat_names[elem]] = dfrm['Category'] == elem

to result in having columns with specified names, rather than just string conversion of the category values. In fact, for some types, str() may not produce anything useful for you.

Merger two image png and jpg/png [Image Masking]

//URL or Local path
$src_url = '1.png';
$dest_url = '2.jpg';
$src = imagecreatefrompng($src_url);
$dest1 = imagecreatefromjpeg($dest_url);

//if you want to make same size
list($width, $height) = getimagesize($dest_url);
list($newWidth, $newHeight) = getimagesize($src_url);
$dest = imagecreatetruecolor($newWidth, $newHeight);

imagecopyresampled($dest, $dest1, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

list($src_w, $src_h) = getimagesize($src_url);

//merger with same size

imagecopymerge_alpha

function imagecopymerge_alpha($dst_im, $src_im, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct)
    {
        $cut = imagecreatetruecolor($src_w, $src_h);
        imagecopy($cut, $dst_im, 0, 0, $dst_x, $dst_y, $src_w, $src_h);
        imagecopy($cut, $src_im, 0, 0, $src_x, $src_y, $src_w, $src_h);
        imagecopymerge($dst_im, $cut, $dst_x, $dst_y, 0, 0, $src_w, $src_h, $pct);
    }

Try this:

var keys = [];
for (var key in dictionary) {
  if (dictionary.hasOwnProperty(key)) {
    keys.push(key);
  }
}

hasOwnProperty is needed because it's possible to insert keys into the prototype object of dictionary. But you typically don't want those keys included in your list.

For example, if you do this:

Object.prototype.c = 3;
var dictionary = {a: 1, b: 2};

and then do a for...in loop over dictionary, you'll get a and b, but you'll also get c.

try it like this:

  <div id="divContainer">
    <div class="divImageHolder">
    IMG HERE
    </div>
    <div class="divImageHolder">
    IMG HERE
    </div>
    <div class="divImageHolder">
    IMG HERE
    </div>
    <br class="clear" />
    </div>

    <style type="text/css">
    #divContainer { margin: 0 auto; width: 800px; }
    .divImageHolder { float:left; }
    .clear { clear:both; }
    </style>

When I saw the same error, I tried to resolve it like:

   __block CGFloat docHeight = 0.0;


    [self evaluateJavaScript:@"document.height" completionHandler:^(id height, NSError *error) {
        //height
        NSLog(@"=========>document.height:@%@",height);
        docHeight = [height floatValue];
    }];

and its working fine

Just add "__block" before Variable.

If you go one level up in running the script in the command line of your bash shell, the issue will be resolved. To do this, use cd .. command to change the working directory in which your script will be running. The result should look like this:

[username@localhost myProgram]$

rather than this:

[username@localhost app]$

Once you are there, instead of running the script in the following format:

python3 mymodule.py

Change it to this:

python3 app/mymodule.py

This process can be repeated once again one level up depending on the structure of your Tree diagram. Please also include the compilation command line that is giving you that mentioned error message.

This problem occurred to me when using nested try- catch and using the $ex->getPrevious() function for logging exception .mabye your code has endless loop. So you first need to check the code and increase the size of the memory if necessary

 try {
        //get latest product data and latest stock from api
        $latestStocksInfo = Product::getLatestProductWithStockFromApi();
    } catch (\Exception $error) {
        try {
            $latestStocksInfo = Product::getLatestProductWithStockFromDb();
        } catch (\Exception $ex) {
            /*log exception */
            Log::channel('report')->error(['message'=>$ex->getMessage(),'file'=>$ex->getFile(),'line'=>$ex->getLine(),'Previous'=>$ex->getPrevious()]);///------------->>>>>>>> this problem when use 
            Log::channel('report')->error(['message'=>$ex->getMessage(),'file'=>$ex->getFile(),'line'=>$ex->getLine()]);///------------->>>>>>>> this code is ok 
        }
        Log::channel('report')->error(['message'=>$error->getMessage(),'file'=>$error->getFile(),'line'=>$error->getLine()]);

        /***log exception ***/
    }

This can also help you by showing full details of the error on a client's browser.

<system.web>
    <customErrors mode="Off"/>
</system.web>
<system.webServer>
    <httpErrors errorMode="Detailed" />

If anyone is looking for a simple solution in Laravel 5.3:

1. Let default timestamps() be saved as is i.e. '2016-11-14 12:19:49'

2. In your views, format the field as below (or as required):

   date('F d, Y', strtotime($list->created_at))
   

It worked for me very well for me.

This is not really CPU friendly, but :

Math.round(number*100)/100

works as expected.

When everything sounded so complicated, this command worked for me:

keytool -genkey -alias foo -keystore cacerts -dname cn=test -storepass changeit -keypass changeit

When a developer is in trouble, I believe a simple working solution snippet is more than enough for him. Later he could diagnose the root cause and basic understanding related to the issue.

The declaration and definition of insertLike are different

In your header file:

void insertLike(const char sentence[], const int lengthTo, const int length, const char writeTo[]);

In your 'function file':

void insertLike(const char sentence[], const int lengthTo, const int length,char writeTo[]);

C++ allows function overloading, where you can have multiple functions/methods with the same name, as long as they have different arguments. The argument types are part of the function's signature.

In this case, insertLike which takes const char* as its fourth parameter and insertLike which takes char * as its fourth parameter are different functions.

Incase their is local uncommitted changes and avoid merge conflict while pulling.

Checks if the given address is a valid web page address.

Description

You can do this using jQuery's .scrollTop() and .offset() method

Check out my sample and this jsFiddle Demonstration

Sample

$(function() {
    $(document).scrollTop( $("#header").offset().top );  
});

More Information

• jsFiddle Demonstration
• jQuery.scrollTop()
• jQuery.offset()

First method you can try this

$department->department_name = $request->department_name;
$department->status = $request->status;
$department->save();

Another way to insert records into the database with create function

$department = new Department;           
// Another Way to insert records
$department->create($request->all());

return redirect('admin/departments');

You need to set the filledby in Department model

namespace App;

use Illuminate\Database\Eloquent\Model;

class Department extends Model
{
    protected $fillable = ['department_name','status'];
} 

For Groovy script in the Jenkinsfile using the $BUILD_NUMBER it works.

Of course you can use multiple versions of Java under Windows. And different applications can use different Java versions. How is your application started? Usually you will have a batch file where there is something like

java ...

This will search the Java executable using the PATH variable. So if Java 5 is first on the PATH, you will have problems running a Java 6 application. You should then modify the batch file to use a certain Java version e.g. by defining a environment variable JAVA6HOME with the value C:\java\java6 (if Java 6 is installed in this directory) and change the batch file calling

%JAVA6HOME%\bin\java ...

The simple and fastest way to count spaces

 String fav="foo hello me hi";
for( int i=0; i<fav.length(); i++ ) {
        if(fav.charAt(i) == ' ' ) {
            counter++;
        }
    }

Why don't you create service and put logic in onCreate(). In this case even if you press back button service will keep on executing. and once you enter into application it will not call onCreate() again. Rather it will call onStart()

Beej's famous network programming guide gives a nice explanation:

In some documentation, you'll see mention of a mystical "PF_INET". This is a weird etherial beast that is rarely seen in nature, but I might as well clarify it a bit here. Once a long time ago, it was thought that maybe a address family (what the "AF" in "AF_INET" stands for) might support several protocols that were referenced by their protocol family (what the "PF" in "PF_INET" stands for).
That didn't happen. Oh well. So the correct thing to do is to use AF_INET in your struct sockaddr_in and PF_INET in your call to socket(). But practically speaking, you can use AF_INET everywhere. And, since that's what W. Richard Stevens does in his book, that's what I'll do here.

I just discovered that LNK2019 occurs during compilation in Visual Studio 2015 if forgetting to provide a definition for a declared function inside a class.

The linker error was highly cryptic, but I narrowed it down to what was missing by reading through the error and provided the definition outside the class to clear this up.

It is the container of the Grid that is imposing on its width. In this case, that's a ListBoxItem, which is left-aligned by default. You can set it to stretch as follows:

<ListBox>
    <!-- other XAML omitted, you just need to add the following bit -->
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalAlignment" Value="Stretch"/>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

Simply put, in the first case, you are assigning multiple names to a list. Only one copy of list is created in memory and all names refer to that location. So changing the list using any of the names will actually modify the list in memory.

In the second case, multiple copies of same value are created in memory. So each copy is independent of one another.

This is how I do it...

public class ThreadA {
    public ThreadA(object[] args) {
        ...
    }
    public void Run() {
        while (true) {
            Thread.sleep(1000); // wait 1 second for something to happen.
            doStuff();
            if(conditionToExitReceived) // what im waiting for...
                break;
        }
        //perform cleanup if there is any...
    }
}

Then to run this in its own thread... ( I do it this way because I also want to send args to the thread)

private void FireThread(){
    Thread thread = new Thread(new ThreadStart(this.startThread));
    thread.start();
}
private void (startThread){
    new ThreadA(args).Run();
}

The thread is created by calling "FireThread()"

The newly created thread will run until its condition to stop is met, then it dies...

You can signal the "main" with delegates, to tell it when the thread has died.. so you can then start the second one...

The best option for me and it works and simple

git pull --rebase

then

git push

best of luck

The following worked, but only after I upgraded PSEXEC to 2.1 from Microsoft.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] "LocalAccountTokenFilterPolicy"=dword:00000001 See: http://forum.sysinternals.com/topic10924.html

I had a slightly older version that didn't work. I used it to do some USMT work via Dell kace, worked a treat :)

You can get access to the options array of a selected object by going document.getElementById("cars").options where 'cars' is the select object.

Once you have that you can call option[i].setAttribute('selected', 'selected'); to select an option.

I agree with every one else that you are better off doing this server side though.

You can use jQuery to make it easy and clear

JSFiddle DEMO

<textarea id="ta" max="10"></textarea>

<script>
$("#ta").keypress(function(e){

    var k = e.which==0 ? e.keyCode : e.which;
    //alert(k);
    if(k==8 || k==37 || k==39 || k==46) return true;

    var text      = $(this).val();
    var maxlength = $(this).attr("max");

    if(text.length >= maxlength) {
        return false;   
    }
    return true;
});
</script>

It is tested in Firefox, Google Chrome and Opera

Select your project and select the "Deployment Descriptor" option and then choose "Generate Deployment Descriptor stub"

you can set the dataset to grid as follows:

//assuming your dataset object is ds

datagridview1.datasource= ds;
datagridview1.datamember= tablename.ToString();

tablename is the name of the table, which you want to show on the grid.

I hope, it helps.

B.R.

Just give a try using subset

nrow(subset(data,condition))

Example

nrow(subset(myData,sCode == "CA"))

On Windows (msys) using Docker Toolbox/Machine, I had to add an extra / before /bin/bash to indicate that it was a *nix filepath.

So, docker run --rm -it <image>:latest //bin/bash

Your calculation is correct for DATE types, but if your values are timestamps, you should probably use EXTRACT (or DATE_PART) to be sure to get only the difference in full days;

EXTRACT(DAY FROM MAX(joindate)-MIN(joindate)) AS DateDifference

An SQLfiddle to test with. Note the timestamp difference being 1 second less than 2 full days.

Use the xattr command. You can inspect the extended attributes:

$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine

and use the -d option to delete one extended attribute:

$ xattr -d com.apple.quarantine s.7z
$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms

you can also use the -c option to remove all extended attributes:

$ xattr -c s.7z
$ xattr s.7z

xattr -h will show you the command line options, and xattr has a man page.

On git version 2.17.1, there isn't a built-in flag to achieve this purpose.

Here's an example command to filter out the filename and line numbers from an unified diff:

git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? @@@)' | paste -s -d':'

For example, the unified diff:

$ git diff --unified=0
diff --cc foobar
index b436f31,df63c58..0000000
--- a/foobar
+++ b/foobar
@@@ -1,2 -1,2 +1,6 @@@ Line abov
++<<<<<<< HEAD
 +bar
++=======
+ foo
++>>>>>>> Commit message

Will result in:

? git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? @@@)' | paste -s -d':'
foobar:1

To match the output of commands in common grep match results:

$ git diff --unified=0 | grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? )| @@@.*' | sed -e '0~3{s/ @@@[ ]\?//}' | sed '2~3 s/$/\n1/g' | sed "N;N;N;s/\n/:/g"
foobar:1:1:Line abov

1. grep -Po '^diff --cc \K.*|^@@@( -[0-9]+,[0-9]+){2} \+\K[0-9]+(?=(,[0-9]+)? ): Match filename from diff --cc <filename> OR Match line number from @@@ <from-file-range> <from-file-range> <to-file-range> OR Match remaining text after @@@.
2. sed -e '0~3{s/ @@@[ ]\?//}': Remove @@@[ ]\? from every 3rd line to get the optional 1 line context before ++<<<<<<< HEAD.
3. sed '2~3 s/$/\n1/g': Add \n1 every 3 lines between the 2nd and 3rd line for the column number.
4. sed "N;N;N;s/\n/:/g": Join every 3 lines with a :.

An input type="image" only defines that image as the submit button and not as an input that can carry over a value to the server.

Try subprocess.call. It saves the return value of the program that was used.

According to my ping manual, it returns 0 on success, 2 when pings were sent but no reply was received and any other value indicates an error.

# typo error in import
import subprocess

for ping in range(1,10):
    address = "127.0.0." + str(ping)
    res = subprocess.call(['ping', '-c', '3', address])
    if res == 0:
        print "ping to", address, "OK"
    elif res == 2:
        print "no response from", address
    else:
        print "ping to", address, "failed!"

go get will install the package in the first directory listed at GOPATH (an environment variable which might contain a colon separated list of directories). You can use go get -u to update existing packages.

You can also use go get -u all to update all packages in your GOPATH

For larger projects, it might be reasonable to create different GOPATHs for each project, so that updating a library in project A wont cause issues in project B.

Type go help gopath to find out more about the GOPATH environment variable.

From an anonymous block? I'd like to now more about the situation where you think that to be required, because with subquery factoring clauses and inline views it's pretty rare that you need to resort to PL/SQL for anything other than the most complex situations.

If you can use a named procedure then use pipelined functions. Here's an example pulled from the documentation:

CREATE PACKAGE pkg1 AS
  TYPE numset_t IS TABLE OF NUMBER;
  FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED;
END pkg1;
/

CREATE PACKAGE BODY pkg1 AS
-- FUNCTION f1 returns a collection of elements (1,2,3,... x)
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED IS
  BEGIN
    FOR i IN 1..x LOOP
      PIPE ROW(i);
    END LOOP;
    RETURN;
  END;
END pkg1;
/

-- pipelined function is used in FROM clause of SELECT statement
SELECT * FROM TABLE(pkg1.f1(5));

Try to use jquery-transport-xdr jQuery plugin for CORS requests in IE8/9.

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

Use this regex (?<!\\)' for searching an unescaped apostrophe. It finds an apostrophe that not preceded by a backslash.

But I wanted to point out that the opinion expressed in the accepted answer is somewhat outdated. According to more recent discussions (django bugs #7634 and #12785), auto_now and auto_now_add are not going anywhere, and even if you go to the original discussion, you'll find strong arguments against the RY (as in DRY) in custom save methods.

A better solution has been offered (custom field types), but didn't gain enough momentum to make it into django. You can write your own in three lines (it's Jacob Kaplan-Moss' suggestion).

from django.db import models
from django.utils import timezone


class AutoDateTimeField(models.DateTimeField):
    def pre_save(self, model_instance, add):
        return timezone.now()

#usage
created_at = models.DateField(default=timezone.now)
updated_at = models.AutoDateTimeField(default=timezone.now)

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Do you want to change database?

What about (1 << (8*sizeof(int)-2)) - 1 + (1 << (8*sizeof(int)-2)). This is the same as 2^(8*sizeof(int)-2) - 1 + 2^(8*sizeof(int)-2).

If sizeof(int) = 4 => 2^(8*4-2) - 1 + 2^(8*4-2) = 2^30 - 1 + 20^30 = (2^32)/2 - 1 [max signed int of 4 bytes].

You can't use 2*(1 << (8*sizeof(int)-2)) - 1 because it will overflow, but (1 << (8*sizeof(int)-2)) - 1 + (1 << (8*sizeof(int)-2)) works.

this is a known problem with CSS resizing, unless all images have the same proportion, you have no way to do this via CSS.

The best approach would be to have a container, and resize one of the dimensions (always the same) of the images. In my example I resized the width.

If the container has a specified dimension (in my example the width), when telling the image to have the width at 100%, it will make it the full width of the container. The auto at the height will make the image have the height proportional to the new width.

Ex:

HTML:

<div class="container">
<img src="something.png" />
</div>

<div class="container">
<img src="something2.png" />
</div>

CSS:

.container {
    width: 200px;
    height: 120px;
}

/* resize images */
.container img {
    width: 100%;
    height: auto;
}

#include <stdio.h>
#include <string.h>
char isNumber(char *text)
{
    int j;
    j = strlen(text);
    while(j--)
    {
        if(text[j] > 47 && text[j] < 58)
            continue;

        return 0;
    }
    return 1;
}
int main(){
    char tmp[16];
    scanf("%s", tmp);

    if(isNumber(tmp))
        return printf("is a number\n");

    return printf("is not a number\n");
}

You can also check its stringfied value, which could also work with non Ascii

char isNumber(char *text)
{
    int j;
    j = strlen(text);
    while(j--)
    {
        if(text[j] >= '0' && text[j] <= '9')
            continue;

        return 0;
    }
    return 1;
}

In general, this happens when you insert strings to columns with incompatible encoding/collation.

I got this error when I had TRIGGERs, which inherit server's collation for some reason. And mysql's default is (at least on Ubuntu) latin-1 with swedish collation. Even though I had database and all tables set to UTF-8, I had yet to set my.cnf:

/etc/mysql/my.cnf :

[mysqld]
character-set-server=utf8
default-character-set=utf8

And this must list all triggers with utf8-*:

select TRIGGER_SCHEMA, TRIGGER_NAME, CHARACTER_SET_CLIENT, COLLATION_CONNECTION, DATABASE_COLLATION from information_schema.TRIGGERS

And some of variables listed by this should also have utf-8-* (no latin-1 or other encoding):

show variables like 'char%';

Request timed out means that the local host did not receive a response from the destination host, but it was able to reach it. Destination host unreachable means that there was no valid route to the requested host.

Here, as the Text widget does not have a property that allows us to define a border, we should wrap it with a widget that allows us to define a border. There are several solutions.
But the best solution is the use of BoxDecoration in the Container widget.

Why choose to use BoxDecoration ?
Because BoxDecoration offers more customization like the possibility to define :
First, the border and also define:

• border Color
• border width
• border radius
• shape
• and more ...

An example :

   Container(
     child:Text(' Hello Word '),
     decoration: BoxDecoration(
          color: Colors.yellow,
          border: Border.all(
                color: Colors.red ,
                width: 2.0 ,
              ),
          borderRadius: BorderRadius.circular(15),
            ),
          ),

Output :

Use preg_grep

$array = preg_grep(
    '/(my\n+string\n+)/i',
    array( 'file' , 'my string  => name', 'this')
);

The only solution I have found is not to set the index to a previous frame and wait (then OpenCV stops reading frames, anyway), but to initialize the capture one more time. So, it looks like this:

cap = cv2.VideoCapture(camera_url)
while True:
    ret, frame = cap.read()

    if not ret:
        cap = cv.VideoCapture(camera_url)
        continue

    # do your processing here

And it works perfectly!

It seems that you need to pass a flag "-l, --log-file"

Usage: kibana [options]

Kibana is an open source (Apache Licensed), browser based analytics and search dashboard for Elasticsearch.

Options:

    -h, --help                 output usage information
    -V, --version              output the version number
    -e, --elasticsearch <uri>  Elasticsearch instance
    -c, --config <path>        Path to the config file
    -p, --port <port>          The port to bind to
    -q, --quiet                Turns off logging
    -H, --host <host>          The host to bind to
    -l, --log-file <path>      The file to log to
    --plugins <path>           Path to scan for plugins

If you use the init script to run as a service, maybe you will need to customize it.

if(frm.product.value=="F"){
    var select = document.getElementsByName('val')[0];
    select.remove(0);
    select.remove(1);
}

Use the following expression:

^[a-zA-Z0-9]*$

ie:

using System.Text.RegularExpressions;

Regex r = new Regex("^[a-zA-Z0-9]*$");
if (r.IsMatch(SomeString)) {
  ...
}

I changed the port. It's worked for me. You can write another port. Example 3355

The _t data types are typedef types in the stdint.h header, while int is an in built fundamental data type. This make the _t available only if stdint.h exists. int on the other hand is guaranteed to exist.

I had the same problem. But i discover that my hd is full.

$ sudo cat /var/log/upstart/mysql.log
/proc/self/fd/9: ERROR: The partition with /var/lib/mysql is too full!

So, I run

$ df -h

And I got the message

/dev/xvda1      7.8G  7.4G     0 100% /

Then I found out which folder was full by running the following command on the terminal

$ cd /var/www
$ for i in *; do echo $i; find $i |wc -l; done

This give me the number of files on each folder on /var/www. I logged into the folder with most files, and deleted some backup files, and i continued deleting useless files and cache files.

then I run $ sudo /etc/init.d/mysql start and it work again

I have an elegant solution to this problem. If you have multiple dataset, identifying which dataset was clicked gets tricky. The _datasetIndex always returns zero. But this should do the trick. It will get you the label and the dataset label as well. Please note ** this.getElementAtEvent** is without the s in getElement

options: {
   onClick: function (e, items) {
    var firstPoint = this.getElementAtEvent(e)[0];
    if (firstPoint) {
      var label = firstPoint._model.label;
      var val = firstPoint._model.datasetLabel;
      console.log(label+" - "+val);
    }
    
  }
}

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.

There are several ways to soften the pain:

JSF EL offers a shorthand to ${pageContext.request} in flavor of #{request}:

<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>

You can if necessary use <c:set> tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:

<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>

JSF 2.x offers the <h:link> which can take a view ID relative to the context root in outcome and it will append the context path and FacesServlet mapping automatically:

<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>

HTML offers the <base> tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>.

<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>

(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring(), see also this answer)

This should end up in the generated HTML something like as

<base href="http://example.com/webname/" />

Note that the <base> tag has a caveat: it makes all jump anchors in the page like <a href="#top"> relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a> or <h:link value="top" fragment="top" />.

If SQL Server Service is running as Local System, than make sure that the folder containing databases should have FULL CONTROL PERMISSION for the Local System account.

This worked for me.

Print all args without the filename:

for i in range(1, len(sys.argv)):
print(sys.argv[i])

I had a similar problem, and after spending so much time and lots of searching about this issue the only trick worked for me:

1. Please Install the Required SDKs as shown in this figure

Configure Required SDKs

2. If You have already installed it, so you must have to update the following SDKs:
   • Android SDK Tool (update it to latest version)
   • Android SDK Platform-tools (update it to latest version)
   • Android SDK Build-tools (update it to latest version)
   • Android Support Repository under Extra folder (update it to latest version)
3. You Must have at least Installed the Same version Android API as the installed Android SDK Build-tools & Android SDK Platform-tools version as shown in the Configure Required SDKs figure above.

Note: Local Maven repository for Support Libraries which is listed as the SDK requirement in the official docs of React-native is now named as Android Support Repository in the SDK Manager .

@Override  
public boolean onInterceptTouchEvent(MotionEvent ev) {
    switch (ev.getAction()) {     
    case MotionEvent.ACTION_DOWN:         
        // if we can scroll pass the event to the superclass      
        if (mScrollable) return super.onInterceptTouchEvent(ev);      
        // only continue to handle the touch event if scrolling enabled    
        return mScrollable; // mScrollable is always false at this point     
        default:          
            return super.onInterceptTouchEvent(ev);      
            }
    }

If Foo is the class enclose this method

class Foo{
  public ArrayList<Integer> myNumbers()    {
     //code code code
  }
}

then

new Foo().myNumbers();

I have a new solution hide the column on client side using css or javascript or jquery.

.col0
{
  display: none;
}

And in the aspx file where you add the column you should specify the CSS properties:

<asp:BoundField HeaderText="Address Key" DataField="Address_Id" ItemStyle-CssClass="col0" HeaderStyle-CssClass="col0" > </asp:BoundField>

Use the onsubmit event to execute JavaScript code when the form is submitted. You can then return false or call the passed event's preventDefault method to disable the form submission.

For example:

<script>
function doSomething() {
    alert('Form submitted!');
    return false;
}
</script>

<form onsubmit="return doSomething();" class="my-form">
    <input type="submit" value="Submit">
</form>

This works, but it's best not to litter your HTML with JavaScript, just as you shouldn't write lots of inline CSS rules. Many Javascript frameworks facilitate this separation of concerns. In jQuery you bind an event using JavaScript code like so:

<script>
$('.my-form').on('submit', function () {
    alert('Form submitted!');
    return false;
});
</script>

<form class="my-form">
    <input type="submit" value="Submit">
</form>

I know this is very old question but I had the same requirement and just discovered that after c#6 you can use static in using for classes to import.

I hope this helps someone....

With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. Some examples:

pygame.draw.rect draws filled rectangular shapes or outlines. The arguments are the target Surface (i.s. the display), the color, the rectangle and the optional outline width. The rectangle argument is a tuple with the 4 components (x, y, width, height), where (x, y) is the upper left point of the rectangle. Alternatively, the argument can be a pygame.Rect object:

pygame.draw.rect(window, color, (x, y, width, height))

rectangle = pygame.Rect(x, y, width, height)
pygame.draw.rect(window, color, rectangle)

pygame.draw.circle draws filled circles or outlines. The arguments are the target Surface (i.s. the display), the color, the center, the radius and the optional outline width. The center argument is a tuple with the 2 components (x, y):

pygame.draw.circle(window, color, (x, y), radius)

pygame.draw.polygon draws filled polygons or contours. The arguments are the target Surface (i.s. the display), the color, a list of points and the optional contour width. Each point is a tuple with the 2 components (x, y):

pygame.draw.polygon(window, color, [(x1, y1), (x2, y2), (x3, y3)])

Minimal example:

import pygame

pygame.init()

window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((255, 255, 255))

    pygame.draw.rect(window, (0, 0, 255), (20, 20, 160, 160))
    pygame.draw.circle(window, (255, 0, 0), (100, 100), 80)
    pygame.draw.polygon(window, (255, 255, 0), 
        [(100, 20), (100 + 0.8660 * 80, 140), (100 - 0.8660 * 80, 140)])

    pygame.display.flip()

pygame.quit()
exit()

This is what I came up with to easily view all data values:

var dataItems = "";_x000D_
$.each(data, function (index, itemData) {_x000D_
    dataItems += index + ": " + itemData + "\n";_x000D_
});_x000D_
console.log(dataItems);

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

There is an implementation in my TypeScript utilities based on JavaScript GUID generators.

Here is the code:

class Guid {_x000D_
  static newGuid() {_x000D_
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {_x000D_
      var r = Math.random() * 16 | 0,_x000D_
        v = c == 'x' ? r : (r & 0x3 | 0x8);_x000D_
      return v.toString(16);_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// Example of a bunch of GUIDs_x000D_
for (var i = 0; i < 100; i++) {_x000D_
  var id = Guid.newGuid();_x000D_
  console.log(id);_x000D_
}

Please note the following:

C# GUIDs are guaranteed to be unique. This solution is very likely to be unique. There is a huge gap between "very likely" and "guaranteed" and you don't want to fall through this gap.

JavaScript-generated GUIDs are great to use as a temporary key that you use while waiting for a server to respond, but I wouldn't necessarily trust them as the primary key in a database. If you are going to rely on a JavaScript-generated GUID, I would be tempted to check a register each time a GUID is created to ensure you haven't got a duplicate (an issue that has come up in the Chrome browser in some cases).

Well, I figured it out. Apparently there is a builtin (?) function called rand:

rand(n + 1)

If someone answers with a more detailed answer, I'll mark that as the correct answer.

In Ruby IO module documentation, I suppose.

Mode |  Meaning
-----+--------------------------------------------------------
"r"  |  Read-only, starts at beginning of file  (default mode).
-----+--------------------------------------------------------
"r+" |  Read-write, starts at beginning of file.
-----+--------------------------------------------------------
"w"  |  Write-only, truncates existing file
     |  to zero length or creates a new file for writing.
-----+--------------------------------------------------------
"w+" |  Read-write, truncates existing file to zero length
     |  or creates a new file for reading and writing.
-----+--------------------------------------------------------
"a"  |  Write-only, starts at end of file if file exists,
     |  otherwise creates a new file for writing.
-----+--------------------------------------------------------
"a+" |  Read-write, starts at end of file if file exists,
     |  otherwise creates a new file for reading and
     |  writing.
-----+--------------------------------------------------------
"b"  |  Binary file mode (may appear with
     |  any of the key letters listed above).
     |  Suppresses EOL <-> CRLF conversion on Windows. And
     |  sets external encoding to ASCII-8BIT unless explicitly

You can use the following:

1. Type Alias (using type keyword, aliasing a function literal)
2. Interface
3. Function Literal

Here is an example of how to use them:

type myCallbackType = (arg1: string, arg2: boolean) => number;

interface myCallbackInterface { (arg1: string, arg2: boolean): number };

class CallbackTest
{
    // ...

    public myCallback2: myCallbackType;
    public myCallback3: myCallbackInterface;
    public myCallback1: (arg1: string, arg2: boolean) => number;

    // ...

}

Use the CREATE TABLE SELECT syntax.

http://dev.mysql.com/doc/refman/5.0/en/create-table-select.html

CREATE TABLE new_tbl SELECT * FROM orig_tbl;

I think the closets thing to "with" is static using, but only works with static's methods or properties. e.g.

using static System.Math;
...
public double Area
{
   get { return PI * Pow(Radius, 2); } // PI == System.Math.PI
}

More Info: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/using-static

JavaScript Pure:

<script type="text/javascript">
document.getElementById("modal").click();
</script>

JQuery:

<script type="text/javascript">
$(document).ready(function(){
    $("#modal").trigger('click'); 
});
</script>

or

<script type="text/javascript">
$(document).ready(function(){
    $("#modal").click(); 
});
</script>

It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;

or

char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);

will print

X
3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';

I have another way to do this... suppose you swap out your message converter to String for your RestTemplate, then you can receive raw JSON. Using the raw JSON, you can then map it into your Generic Collection using a Jackson Object Mapper. Here's how:

Swap out the message converter:

    List<HttpMessageConverter<?>> oldConverters = new ArrayList<HttpMessageConverter<?>>();
    oldConverters.addAll(template.getMessageConverters());

    List<HttpMessageConverter<?>> stringConverter = new ArrayList<HttpMessageConverter<?>>();
    stringConverter.add(new StringHttpMessageConverter());

    template.setMessageConverters(stringConverter);

Then get your JSON response like this:

    ResponseEntity<String> response = template.exchange(uri, HttpMethod.GET, null, String.class);

Process the response like this:

     String body = null;
     List<T> result = new ArrayList<T>();
     ObjectMapper mapper = new ObjectMapper();

     if (response.hasBody()) {
        body = items.getBody();
        try {
            result = mapper.readValue(body, mapper.getTypeFactory().constructCollectionType(List.class, clazz));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            template.setMessageConverters(oldConverters);
        }
        ...

if (grid.selectedKeyNames().length > 0) {
            $('#btnRemoveFromList').show();
        } else {
            $('#btnRemoveFromList').hide();
        }

}

() - calls the method

no parentheses - returns the property

Right click on the service in service.msc and select property.

You will see a folder path under Path to executable like C:\Users\Me\Desktop\project\Tor\Tor\tor.exe

Navigate to C:\Users\Me\Desktop\project\Tor and right click on Tor.

Select property, security, edit and then add. In the text field enter LOCAL SERVICE, click ok and then check the box FULL CONTROL

Click on add again then enter NETWORK SERVICE, click ok, check the box FULL CONTROL

Then click ok (at the bottom)

This is now no longer needed for Java 9, nor for any recent release of Java 6, 7, or 8. Finally! :)

Per JDK-8170157, the unlimited cryptographic policy is now enabled by default.

Specific versions from the JIRA issue:

• Java 9 (10, 11, etc..): Any official release!
• Java 8u161 or later (Available now)
• Java 7u171 or later (Only available through 'My Oracle Support')
• Java 6u181 or later (Only available through 'My Oracle Support')

Note that if for some odd reason the old behavior is needed in Java 9, it can be set using:

Security.setProperty("crypto.policy", "limited");

If you want to use datetime class

$dt = new DateTime();
echo $dt->format('Y-m-d H:i:s');

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

In addition to the anwser of Bill the Lizard:

Most of the backends parse the raw post data. In PHP for example, you will have an array $_POST in which individual variables within the post data will be stored. In this case you have to use an additional header "Content-type: application/x-www-form-urlencoded":

Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
objHTTP.send ("var1=value1&var2=value2&var3=value3")

Otherwise you have to read the raw post data on the variable "$HTTP_RAW_POST_DATA".

http://jsbin.com/qamuyajipo/3/edit?html,output

.circle {
    border: 1px solid red;
    background-color: #FFFFFF;

    -webkit-border-radius: 75px;
    width: 100px;
}

You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:

<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>

</body>
</html>

Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.

Return function is not working in all the cases. I tried this:

<button id="Reset" class="Button-class" onclick="return Reset()">Show result</button>

It didnt work for me.

I tried to return false inside the function and it worked for me.

function Reset()
{
    .
    .
    .
    return false;
}

changing style with jquery

Try This

$('#selector_id').css('display','none');

You can also change multiple attribute in a single query

Try This

$('#replace-div').css({'padding-top': '5px' , 'margin' : '10px'});

You can use this   or

$('select').change(function() {
    var a=$(':selected').text(); // "city1city2choose iofoo"
    var b=$(':selected').val();  // "city1" - selects just first query !
    //but..
    var c=$(':selected').map(function(){ // ["city1","city2","choose io","foo"]
        return $(this).text();
    }); 
    var d=$(':selected').map(function(){ // ["city1","c2","s1","s5"]

private void btnDelete_Click(object sender, EventArgs e)
{
    if (e.ColumIndex == 10)// 10th column the button
    {
        dataGridView1.Rows.Remove(dataGridView1.Rows[e.RowIndex]);
    }                
}

This solution can be delete a row (not selected, clicked row!) via "e" param.

I know this thread is old... but in "modern times".. there is a far superior "include strategy" via clang's @import modules - that is oft-overlooked..

Modules improve access to the API of software libraries by replacing the textual preprocessor inclusion model with a more robust, more efficient semantic model. From the user’s perspective, the code looks only slightly different, because one uses an import declaration rather than a #include preprocessor directive:

@import Darwin; // Like including all of /usr/include. @see /usr/include/module.map

or

@import Foundation;  //  Like #import <Foundation/Foundation.h>
@import ObjectiveC;  //  Like #import <objc/runtime.h>

However, this module import behaves quite differently from the corresponding #include: when the compiler sees the module import above, it loads a binary representation of the module and makes its API available to the application directly. Preprocessor definitions that precede the import declaration have no impact on the API provided... because the module itself was compiled as a separate, standalone module. Additionally, any linker flags required to use the module will automatically be provided when the module is imported. This semantic import model addresses many of the problems of the preprocessor inclusion model.

To enable modules, pass the command-line flag -fmodules aka CLANG_ENABLE_MODULES in Xcode- at compile time. As mentioned above.. this strategy obviates ANY and ALL LDFLAGS. As in, you can REMOVE any "OTHER_LDFLAGS" settings, as well as any "Linking" phases..

I find compile / launch times to "feel" much snappier (or possibly, there's just less of a lag while "linking"?).. and also, provides a great opportunity to purge the now extraneous Project-Prefix.pch file, and corresponding build settings, GCC_INCREASE_PRECOMPILED_HEADER_SHARING, GCC_PRECOMPILE_PREFIX_HEADER, and GCC_PREFIX_HEADER, etc.

Also, while not well-documented… You can create module.maps for your own frameworks and include them in the same convenient fashion. You can take a look at my ObjC-Clang-Modules github repo for some examples of how to implement such miracles.

I have MAC OS X Yosemite, Android Studio 1.0.1, JDK 1.8, and Cordova 4.1.2

When I tried to add the android project:

cordova platforms add android

I received the message: ANDROID_HOME is not set and "android" command not in your PATH

Based in cforcloud's answer... 'Error: the command "android" failed' using cordova and http://developer.android.com/sdk/installing/index.html?pkg=studio I used the following:

export ANDROID_HOME="/Users/<user_name>/Library/Android/sdk"
export ANDROID_TOOLS="/Users/<user_name>/Library/Android/sdk/tools/"
export ANDROID_PLATFORM_TOOLS="/Users/<user_name>/Library/Android/sdk/platform-tools/"
PATH=$PATH:$ANDROID_HOME:$ANDROID_TOOLS:$ANDROID_PLATFORM_TOOLS
echo $PATH

When I tried to create the android project, I received this message:

If you want to connect to SQL server remotly you need to use a software - like Sql Server Management studio.

The computers doesn't need to be on the same network - but they must be able to connect each other using a communication protocol like tcp/ip, and the server must be set up to support incoming connection of the type you choose.

if you want to connect to another computer (to browse files ?) you use other tools, and not sql server (you can map a drive and access it through there ect...)

To Enable SQL connection using tcp/ip read this article:

For Sql Express: express For Sql 2008: 2008

Make sure you enable access through the machine firewall as well.

You might need to install either SSMS or Toad on the machine your using to connect to the server. both you can download from their's company web site.

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

I came up with a mix of defining a class like David's answer, but not requiring a Where class to go with it. It looks something like:

var resultsGroupings = resultsRecords.GroupBy(r => new { r.IdObj1, r.IdObj2, r.IdObj3})
                                    .Select(r => new ResultGrouping {
                                        IdObj1= r.Key.IdObj1,
                                        IdObj2= r.Key.IdObj2,
                                        IdObj3= r.Key.IdObj3,
                                        Results = r.ToArray(),
                                        Count = r.Count()
                                    });



private class ResultGrouping
        {
            public short IdObj1{ get; set; }
            public short IdObj2{ get; set; }
            public int IdObj3{ get; set; }

            public ResultCsvImport[] Results { get; set; }
            public int Count { get; set; }
        }

Where resultRecords is my initial list I'm grouping, and its a List<ResultCsvImport>. Note that the idea here to is that, I'm grouping by 3 columns, IdObj1 and IdObj2 and IdObj3

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

Of course, "Fagner Antunes Dornelles" is correct in its answer. But it seems to me that it is worth checking the registry branch itself in addition, or be sure of the part that is exactly there.

For example ("dirty hack"), i need to establish trust in the RMS infrastructure, otherwise when i open Word or Excel documents, i will be prompted for "Active Directory Rights Management Services". Here's how i can add remote trust to me servers in the enterprise infrastructure.

foreach (var strServer in listServer)
{
    try
    {
        RegistryKey regCurrentUser = Registry.CurrentUser.OpenSubKey($"Software\\Classes\\Local Settings\\Software\\Microsoft\\MSIPC\\{strServer}", false);
        if (regCurrentUser == null)
            throw new ApplicationException("Not found registry SubKey ...");
        if (regCurrentUser.GetValueNames().Contains("UserConsent") == false)
            throw new ApplicationException("Not found value in SubKey ...");
    }
    catch (ApplicationException appEx)
    {
        Console.WriteLine(appEx);
        try
        {
            RegistryKey regCurrentUser = Registry.CurrentUser.OpenSubKey($"Software\\Classes\\Local Settings\\Software\\Microsoft\\MSIPC", true);
            RegistryKey newKey = regCurrentUser.CreateSubKey(strServer, true);
            newKey.SetValue("UserConsent", 1, RegistryValueKind.DWord);
        }
        catch(Exception ex)
        {
            Console.WriteLine($"{ex} Pipec kakoito ...");
        }

This problem was caused by an orphaned SQL Login. I ran my favorite sp_fixusers script and the error was resolved. The suggestion above to look at the logs was a good one...and it led me to my answer.

You need to set the Format of the DateTimePicker to Custom and then assign the CustomFormat.

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    DateTimePicker1.Format = DateTimePickerFormat.Custom
    DateTimePicker1.CustomFormat = "dd/MM/yyyy"
End Sub

Building off of Fabio's answer, I created two functions that will probably be useful for anyone stumbling upon this question. With these two functions, you can call insertParam() with a key and value as an argument. It will either add the URL parameter or, if a query param already exists with the same key, it will change that parameter to the new value:

//function to remove query params from a URL
function removeURLParameter(url, parameter) {
    //better to use l.search if you have a location/link object
    var urlparts= url.split('?');   
    if (urlparts.length>=2) {

        var prefix= encodeURIComponent(parameter)+'=';
        var pars= urlparts[1].split(/[&;]/g);

        //reverse iteration as may be destructive
        for (var i= pars.length; i-- > 0;) {    
            //idiom for string.startsWith
            if (pars[i].lastIndexOf(prefix, 0) !== -1) {  
                pars.splice(i, 1);
            }
        }

        url= urlparts[0] + (pars.length > 0 ? '?' + pars.join('&') : "");
        return url;
    } else {
        return url;
    }
}

//function to add/update query params
function insertParam(key, value) {
    if (history.pushState) {
        // var newurl = window.location.protocol + "//" + window.location.host + search.pathname + '?myNewUrlQuery=1';
        var currentUrlWithOutHash = window.location.origin + window.location.pathname + window.location.search;
        var hash = window.location.hash
        //remove any param for the same key
        var currentUrlWithOutHash = removeURLParameter(currentUrlWithOutHash, key);

        //figure out if we need to add the param with a ? or a &
        var queryStart;
        if(currentUrlWithOutHash.indexOf('?') !== -1){
            queryStart = '&';
        } else {
            queryStart = '?';
        }

        var newurl = currentUrlWithOutHash + queryStart + key + '=' + value + hash
        window.history.pushState({path:newurl},'',newurl);
    }
}

The thing about classes, and setting unencumbered global variables equal to some value within the class, is that what your global variable stores is actually the reference to the memory location the value is actually stored.

What you're seeing in your output is indicative of this.

Where you might be able to see the value and use print without issue on the initial global variables you used because of the str method and how print works, you won't be able to do this with lists, because what is stored in the elements within that list is just a reference to the memory location of the value -- read up on aliases, if you'd like to know more.

Additionally, when using lists and losing track of what is an alias and what is not, you might find you're changing the value of the original list element, if you change it in an alias list -- because again, when you set a list element equal to a list or element within a list, the new list only stores the reference to the memory location (it doesn't actually create new memory space specific to that new variable). This is where deepcopy comes in handy!

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

The one exception worth noting is that while you can't delete apps, the folks over at Google Play Developer Support are able to on their end if the app is both unpublished and has 0 lifetime installs. So if your app has 0 lifetime installs, you might be in luck.

First you will need unpublish the app and wait 24 hours (to allow global stats to update and ensure that no last-minute installs happened). Assuming no last-minute installs happen over those 24 hours, you can contact Google Play Developer Support and check to see if they can delete it.

Please note that their requirement for 0 installs is a hard requirement. No exceptions can be made (not even if you installed the app yourself for testing purposes).

var uniq = allvalues.GroupBy(x => x.Id).Select(y=>y.First()).Distinct();

Easy and simple

@Matt Dodges answer put me on the right track. Thanks again for all the answers, which helped a lot of guys in the mean time. Got it working like this:

SELECT *
FROM feeds f
LEFT JOIN artists a ON a.artist_id = (
    SELECT artist_id
    FROM feeds_artists fa 
    WHERE fa.feed_id = f.id
    LIMIT 1
)
WHERE f.id = '13815'

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

This could help you. It is a way to handle the touch outside event:

How to cancel an Dialog themed like Activity when touched outside the window?

By catching the event and doing nothing, I think you can prevent the closing. But what is strange though, is that the default behavior of your activity dialog should be not to close itself when you touch outside.

(PS: the code uses WindowManager.LayoutParams)

If you're trying to just count how many of your cells in a range are not blank try this:

=COUNTA(range)

Example: (assume that it starts from A1 downwards):

---------    
Something 
---------
Something
---------

---------
Something
---------

---------
Something
---------

=COUNTA(A1:A6) returns 4 since there are two blank cells in there.

It will create a table and copy all the data from old table to new table

SELECT * INTO event_log_temp FROM event_log

And you can clear the old table data.

DELETE FROM event_log

If you do "docker attach "container id" you get into the container. To exit from the container without stopping the container you need to enter Ctrl+P+Q

Sounds like you want to use BitmapDrawable

From the documentation:

A Drawable that wraps a bitmap and can be tiled, stretched, or aligned. You can create a BitmapDrawable from a file path, an input stream, through XML inflation, or from a Bitmap object.

The simplest way especially if you don't have a context, if you're using RxAndroid you can do:

AndroidSchedulers.mainThread().scheduleDirect {
    runCodeHere()
}

Following @Anupam's answer on OS X resulted in the following error for me, regardless of permissions I ran it with:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: ...

What eventually worked was to download a newer pip package (9.0.3) from PyPI directly from my browser - https://pypi.org/simple/pip/, extract the contents, and then pip install the package locally:

pip install ./pip-9.0.3/

This fixed my [SSL: TLSV1_ALERT_PROTOCOL_VERSION] errors.

Normal money conversions will preserve individual pennies:

SELECT convert(varchar(30), moneyfield, 1)

The last parameter decides what the output format looks like:

0 (default) No commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 4235.98.

1 Commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 3,510.92.

2 No commas every three digits to the left of the decimal point, and four digits to the right of the decimal point; for example, 4235.9819.

If you want to truncate the pennies, and count in pounds, you can use rounding to the nearest pound, floor to the lowest whole pound, or ceiling to round up the pounds:

SELECT convert(int, round(moneyfield, 0))
SELECT convert(int, floor(moneyfield))
SELECT convert(int, ceiling(moneyfield))

Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!

This is due to the interfering messages that come on to the page. There are multiple frames on the page which communicate with the page using window message event and object. few of them can be third party services like cookieq for managing cookies, or may be cartwire an e-com integration service.

You need to handle the onmessage event to check from where the messages are coming, and then parse the JSON accordingly.

I faced a similar problem, where one of the integration was passing a JSON object and other was passing a string starting with u

This should work:

public static final byte[] intToByteArray(int value) {
    return new byte[] {
            (byte)(value >>> 24),
            (byte)(value >>> 16),
            (byte)(value >>> 8),
            (byte)value};
}

Code taken from here.

Edit An even simpler solution is given in this thread.

I know that is to late, but I want to share my answer. What I did it's save de script's tags in a HTML file, locking up the scripts on my Index file in a div with an id, something like this.

<div id="ScriptsReload"><script src="js/script.js"></script></div>

and when I wanted to refresh I just used.

$("#ScriptsReload").load("html_with_scripts_tags.html", "", function(
    response,
    status,
    request
  ) {

  });

params is for GET-style URL parameters, data is for POST-style body information. It is perfectly legal to provide both types of information in a request, and your request does so too, but you encoded the URL parameters into the URL already.

Your raw post contains JSON data though. requests can handle JSON encoding for you, and it'll set the correct Content-Type header too; all you need to do is pass in the Python object to be encoded as JSON into the json keyword argument.

You could split out the URL parameters as well:

params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

then post your data with:

import requests

url = 'http://192.168.3.45:8080/api/v2/event/log'

data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

requests.post(url, params=params, json=data)

The json keyword is new in requests version 2.4.2; if you still have to use an older version, encode the JSON manually using the json module and post the encoded result as the data key; you will have to explicitly set the Content-Type header in that case:

import requests
import json

headers = {'content-type': 'application/json'}
url = 'http://192.168.3.45:8080/api/v2/event/log'

data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}

requests.post(url, params=params, data=json.dumps(data), headers=headers)
