I've ran into the same problem recently. After finding the correct path to the pyuic4 file using the file finder I've ran:

C:\Users\ricckli.qgis2\python\plugins\qgis2leaf>C:\OSGeo4W64\bin\pyuic4 -o ui_q gis2leaf.py ui_qgis2leaf.ui

As you can see my ui file was placed in this folder...

QT Creator was installed separately and the pyuic4 file was placed there with the OSGEO4W installer

Print a unicode character in Python:

Print a unicode character directly from python interpreter:

el@apollo:~$ python
Python 2.7.3
>>> print u'\u2713'
?

Unicode character u'\u2713' is a checkmark. The interpreter prints the checkmark on the screen.

Print a unicode character from a python script:

Put this in test.py:

#!/usr/bin/python
print("here is your checkmark: " + u'\u2713');

Run it like this:

el@apollo:~$ python test.py
here is your checkmark: ?

If it doesn't show a checkmark for you, then the problem could be elsewhere, like the terminal settings or something you are doing with stream redirection.

Store unicode characters in a file:

Save this to file: foo.py:

#!/usr/bin/python -tt
# -*- coding: utf-8 -*-
import codecs
import sys 
UTF8Writer = codecs.getwriter('utf8')
sys.stdout = UTF8Writer(sys.stdout)
print(u'e with obfuscation: é')

Run it and pipe output to file:

python foo.py > tmp.txt

Open tmp.txt and look inside, you see this:

el@apollo:~$ cat tmp.txt 
e with obfuscation: é

Thus you have saved unicode e with a obfuscation mark on it to a file.

I believe for databases which support listagg function, you can do:

select id, issue, customfield, parentkey, listagg(stingvalue, ',') within group (order by id)
from jira.customfieldvalue
where customfield = 12534 and issue = 19602
group by id, issue, customfield, parentkey

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

An alternative solution can be found in a comment to this request for enhancement. It uses the getClassContext() method of a custom SecurityManager and seems to be faster than the stack trace method.

The following program tests the speed of the different suggested methods (the most interesting bit is in the inner class SecurityManagerMethod):

/**
 * Test the speed of various methods for getting the caller class name
 */
public class TestGetCallerClassName {

  /**
   * Abstract class for testing different methods of getting the caller class name
   */
  private static abstract class GetCallerClassNameMethod {
      public abstract String getCallerClassName(int callStackDepth);
      public abstract String getMethodName();
  }

  /**
   * Uses the internal Reflection class
   */
  private static class ReflectionMethod extends GetCallerClassNameMethod {
      public String getCallerClassName(int callStackDepth) {
          return sun.reflect.Reflection.getCallerClass(callStackDepth).getName();
      }

      public String getMethodName() {
          return "Reflection";
      }
  }

  /**
   * Get a stack trace from the current thread
   */
  private static class ThreadStackTraceMethod extends GetCallerClassNameMethod {
      public String  getCallerClassName(int callStackDepth) {
          return Thread.currentThread().getStackTrace()[callStackDepth].getClassName();
      }

      public String getMethodName() {
          return "Current Thread StackTrace";
      }
  }

  /**
   * Get a stack trace from a new Throwable
   */
  private static class ThrowableStackTraceMethod extends GetCallerClassNameMethod {

      public String getCallerClassName(int callStackDepth) {
          return new Throwable().getStackTrace()[callStackDepth].getClassName();
      }

      public String getMethodName() {
          return "Throwable StackTrace";
      }
  }

  /**
   * Use the SecurityManager.getClassContext()
   */
  private static class SecurityManagerMethod extends GetCallerClassNameMethod {
      public String  getCallerClassName(int callStackDepth) {
          return mySecurityManager.getCallerClassName(callStackDepth);
      }

      public String getMethodName() {
          return "SecurityManager";
      }

      /** 
       * A custom security manager that exposes the getClassContext() information
       */
      static class MySecurityManager extends SecurityManager {
          public String getCallerClassName(int callStackDepth) {
              return getClassContext()[callStackDepth].getName();
          }
      }

      private final static MySecurityManager mySecurityManager =
          new MySecurityManager();
  }

  /**
   * Test all four methods
   */
  public static void main(String[] args) {
      testMethod(new ReflectionMethod());
      testMethod(new ThreadStackTraceMethod());
      testMethod(new ThrowableStackTraceMethod());
      testMethod(new SecurityManagerMethod());
  }

  private static void testMethod(GetCallerClassNameMethod method) {
      long startTime = System.nanoTime();
      String className = null;
      for (int i = 0; i < 1000000; i++) {
          className = method.getCallerClassName(2);
      }
      printElapsedTime(method.getMethodName(), startTime);
  }

  private static void printElapsedTime(String title, long startTime) {
      System.out.println(title + ": " + ((double)(System.nanoTime() - startTime))/1000000 + " ms.");
  }
}

An example of the output from my 2.4 GHz Intel Core 2 Duo MacBook running Java 1.6.0_17:

Reflection: 10.195 ms.
Current Thread StackTrace: 5886.964 ms.
Throwable StackTrace: 4700.073 ms.
SecurityManager: 1046.804 ms.

The internal Reflection method is much faster than the others. Getting a stack trace from a newly created Throwable is faster than getting it from the current Thread. And among the non-internal ways of finding the caller class the custom SecurityManager seems to be the fastest.

Update

As lyomi points out in this comment the sun.reflect.Reflection.getCallerClass() method has been disabled by default in Java 7 update 40 and removed completely in Java 8. Read more about this in this issue in the Java bug database.

Update 2

As zammbi has found, Oracle was forced to back out of the change that removed the sun.reflect.Reflection.getCallerClass(). It is still available in Java 8 (but it is deprecated).

Update 3

3 years after: Update on timing with current JVM.

If you want to pause then use java.util.concurrent.TimeUnit:

TimeUnit.SECONDS.sleep(1);

To sleep for one second or

TimeUnit.MINUTES.sleep(1);

To sleep for a minute.

As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this is an issue then don't use sleep.

Further, sleep isn't very flexible when it comes to control.

For running a task every second or at a one second delay I would strongly recommend a ScheduledExecutorService and either scheduleAtFixedRate or scheduleWithFixedDelay.

For example, to run the method myTask every second (Java 8):

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

And in Java 7:

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            myTask();
        }
    }, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

'use strict'
var fs = require("fs");

/***
 * implementation of readFileSync
 */
var data = fs.readFileSync('input.txt');
console.log(data.toString());
console.log("Program Ended");

/***
 * implementation of readFile 
 */
fs.readFile('input.txt', function (err, data) {
    if (err) return console.error(err);
   console.log(data.toString());
});

console.log("Program Ended");

For better understanding run the above code and compare the results..

You may need to double-check your SSH identities file. You may be guiding BitBucket to look at a different/incorrect private key to the equivalent public key that you have saved on BitBucket.

Check it with tail ~/.ssh/config - you will see something similar to:

Host bitbucket.org
 HostName bitbucket.org
 IdentityFile ~/.ssh/personal-bitbucket-ssh-key

Remember, that adding additional identities (such as work and home) can be done with the ssh-add command, for example:

ssh-keygen -t rsa -C "companyName" -f "companyName"
ssh-add ~/.ssh/companyName

Once you have confirmed which private key is being looked at locally, you can then take your public equivalent, in this case:

cat ~/.ssh/personal-bitbucket-ssh-key.pub | pbcopy

And paste that cipher onto BitBucket. Your git pushes will now (provided you are using the SSH clone as aforementioned answers have pointed out) be allowed without a password, as your device is a recognised friendly.

Hopefully this helps clear it up for someone.

Because this is just how Python works - keywords such as class and def are not declarations. Instead, they are real live statements which are executed. If they were not executed your module would be .. empty :-)

Anyway, the idiomatic approach is:

# stuff to run always here such as class/def
def main():
    pass

if __name__ == "__main__":
   # stuff only to run when not called via 'import' here
   main()

See What is if __name__ == "__main__" for?

It does require source control over the module being imported, however.

Happy coding.

Another option is the openxlsx-package. It doesn't depend on java and can read, edit and write Excel-files. From the description from the package:

openxlsx simplifies the the process of writing and styling Excel xlsx files from R and removes the dependency on Java

Example usage:

library(openxlsx)

# read data from an Excel file or Workbook object into a data.frame
df <- read.xlsx('name-of-your-excel-file.xlsx')

# for writing a data.frame or list of data.frames to an xlsx file
write.xlsx(df, 'name-of-your-excel-file.xlsx')

Besides these two basic functions, the openxlsx-package has a host of other functions for manipulating Excel-files.

For example, with the writeDataTable-function you can create formatted tables in an Excel-file.

Very simple answer to this use this: \d*

I followed the link to RFC1034 and read most of it and was surprised to see this:

The labels must follow the rules for ARPANET host names. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen. There are also some restrictions on the length. Labels must be 63 characters or less.

For clarification, a domain names are made up of labels which are separated by dots ".". This spec must be outdated because it doesn't mention the use of underscores. I can understand the confusion if anybody stumbles over this spec without knowing it is obsolete. It is obsolete, isn't it?

I followed the link to RFC2181 and read some of it. Especially where it pertains to the issue of what is an authoritative, or canonical, name and the issue of what makes a valid DNS label.

As posted earlier it states there's only a length restriction then to sum it up it reads:

(about names and valid labels)

These are already adequately specified, however the specifications seem to be sometimes ignored. We seek to reinforce the existing specifications.

Kind of leaves me wondering if "a length only restriction" is "adequate". Are we going to start seeing domain names like @#$%!! soon? Isn't the internet screwed up enough?

Calendar has a set() method that can set the year, month, and day-of-month in one call:

myCal.set( theYear, theMonth, theDay );

With the Androidx library and Material Components Theme you can override the getTheme() method:

import androidx.fragment.app.DialogFragment

class RoundedDialog: DialogFragment() {

    override fun getTheme() = R.style.RoundedCornersDialog

    //....

}

with:

<style name="RoundedCornersDialog" parent="@style/Theme.MaterialComponents.Dialog">
    <item name="dialogCornerRadius">16dp</item>
</style>

Or you can use the MaterialAlertDialogBuilder included in the Material Components Library:

import androidx.fragment.app.DialogFragment
import com.google.android.material.dialog.MaterialAlertDialogBuilder

class RoundedAlertDialog : DialogFragment() {

    //...

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        return MaterialAlertDialogBuilder(requireActivity(), R.style.MaterialAlertDialog_rounded)
                .setTitle("Test")
                .setMessage("Message")
                .setPositiveButton("OK", null)
                .create()
    }

}

with:

<style name="MaterialAlertDialog_rounded" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="shapeAppearanceOverlay">@style/DialogCorners</item>
</style>

<style name="DialogCorners">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">16dp</item>
</style>

If you don't need a DialogFragment just use the MaterialAlertDialogBuilder.

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

Following solution is better than bootbox.js, because

• It can do everything bootbox.js can do;
• The use syntax is simpler
• It allows you to elegantly control the color of your message using "error", "warning" or "info"
• Bootbox is 986 lines long, mine only 110 lines long

Rather simple:

Key = i.ToString("D2");

D stands for "decimal number", 2 for the number of digits to print.

dialog.setCanceledOnTouchOutside(true); 

to close dialog on touch outside.

And if you don't want to close on touch outside, use the code below:

dialog.setCanceledOnTouchOutside(false);

I had to manage a scenario where the percentage of duplicates being provided in the new data records was very high, and so many thousands of database calls were being made to check for duplicates (so the CPU sent a lot of time at 100%). In the end I decided to keep the last 100,000 records cached in memory. This way I could check for duplicates against the cached records which was extremely fast when compared to a LINQ query against the SQL database, and then write any genuinely new records to the database (as well as add them to the data cache, which I also sorted and trimmed to keep its length manageable).

Note that the raw data was a CSV file that contained many individual records that had to be parsed. The records in each consecutive file (which came at a rate of about 1 every 5 minutes) overlapped considerably, hence the high percentage of duplicates.

In short, if you have timestamped raw data coming in, pretty much in order, then using a memory cache might help with the record duplication check.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

You can use Oracle.ManagedDataAccess NuGet package too (.NET >= 4.0, database >= 10g Release 2).

You cannot change the default but there is a codeless workaround.

Select the whole sheet and change the font size on your data to something small, like 10 or 12. When you zoom in to view the data you will find that the drop down box entries are now visible.

To emphasize, the issue is not so much with the size of the font in the drop down, it is the relative size between drop down and data display font sizes.

You also can Redirect within the Route as follows. This is for handle invalid routes.

<Route path='*' render={() => 
     (
       <Redirect to="/error"/>
     )
}/>

Here is a solution that creates a section that is expandable using somewhat material design, bootstrap 4.5/5 alpha and entirely non-javascript.

Style for head section

<style>
[data-toggle="collapse"] .fa:before {
    content: "\f077";
}

[data-toggle="collapse"].collapsed .fa:before {
    content: "\f078";
}
</style>

Body html

<div class="pt-3 pb-3" style="border-top: 1px solid #eeeeee; border-bottom: 1px solid #eeeeee; cursor: pointer;">
<a href="#expandId" class="text-dark float-right collapsed" data-toggle="collapse" role="button" aria-expanded="false" aria-controls="expandId">
    <i class="fa" aria-hidden="false"></i>
</a>
<a href="#expandId" class="text-dark collapsed" data-toggle="collapse" role="button" aria-expanded="false" aria-controls="expandId">Expand Header</a>
<div class="collapse" id="expandId">
    CONTENT GOES IN HERE
</div>

You may have more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in your application. Try setting a breakpoint on the setLocations method of the superclass and see if it's called more than once at application startup. If there is more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer, you might need to look at configuring the ignoreUnresolvablePlaceholders property so that your application will start up cleanly.

synchronized is a keyword in Java which is used to make happens before relationship in multithreading environment to avoid memory inconsistency and thread interference error.

If you define your function to take argument of std::vector<int>& arr and integer value, then you can use push_back inside that function:

void do_something(int el, std::vector<int>& arr)
{
    arr.push_back(el);
    //....
}

usage:

std::vector<int> arr;
do_something(1, arr); 

>>> dict(zip(keys, values))
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

To get the values use

sorted(data.values())

To get the matching keys, use a key function

sorted(data, key=data.get)

To get a list of tuples ordered by value

sorted(data.items(), key=lambda x:x[1])

Related: see the discussion here: Dictionaries are ordered in Python 3.6+

php.ini probably needs to read: extension=ext\php_sqlsrv_53_nts.dll

Or move the file to same directory as the php executable. This is what I did to my php5 install this week to get odbc_pdo working. :P

Additionally, that doesn't look like proper phpinfo() output. If you make a file with contents
<? phpinfo(); ?> and visit that page, the HTML output should show several sections, including one with loaded modules. (Edited to add: like shown in the screenshot of the above accepted answer)

In my case:

-console.log()  // works
-console.error() // works
-app.use(logger('dev')) // Morgan is NOT logging requests that look like "GET /myURL 304 9.072 ms - -"

FIX: I was using Visual Studio code, and I had to add this to my Launch Config

"outputCapture": "std"

Suggestion, in case you are running from an IDE, run directly from the command line to make sure the IDE is not causing the problem.

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

Install

If you use homebrew (which I recommend), you can install selenium using:

brew install selenium-server-standalone

Running

updated -port port_number

To run selenium, do: selenium-server -port 4444

For more options: selenium-server -help

Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).

Anyways, if you're already planning on using MSYS2, there's no need for that installer.

1. Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).

2. After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).

3. Install a toolchain

   a) for 32-bit:

   pacman -S mingw-w64-i686-gcc
   

   b) for 64-bit:

   pacman -S mingw-w64-x86_64-gcc
   

4. install any libraries/tools you may need. You can search the repositories by doing

   pacman -Ss name_of_something_i_want_to_install
   

   e.g.

   pacman -Ss gsl
   

   and install using

   pacman -S package_name_of_something_i_want_to_install
   

   e.g.

   pacman -S mingw-w64-x86_64-gsl
   

   and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!

5. Open a MinGW-w64 shell:

   a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"

   b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"

6. Verify that the compiler is working by doing

   gcc -v
   

If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin or <MSYS2 root>/mingw64/bin to your PATH.

You can use the CSS property max-width and use it with ch unit.
And, as this is a <span>, use a display: inline-block; (or block).

Here is an example:

<span style="
  display:inline-block;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  max-width: 13ch;">
Lorem ipsum dolor sit amet
</span>

Which outputs:

Lorem ipsum...

<span style="_x000D_
  display:inline-block;_x000D_
  white-space: nowrap;_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
  max-width: 13ch;">_x000D_
Lorem ipsum dolor sit amet_x000D_
</span>

You want:

java -cp myJar.jar myClass

The Documentation gives the following example:

C:> java -classpath C:\java\MyClasses\myclasses.jar utility.myapp.Cool

You'll need to join twice:

SELECT home.*, away.*, g.network, g.date_start 
FROM game AS g
INNER JOIN team AS home
  ON home.importid = g.home
INNER JOIN team AS away
  ON away.importid = g.away
ORDER BY g.date_start DESC 
LIMIT 7

Same way as @loonis suggested to use TransactionTemplate one may use this helper component (Kotlin):

@Component
class TransactionalUtils {
    /**
     * Execute any [block] of code (even private methods)
     * as if it was effectively [Transactional]
     */
    @Transactional
    fun <R> executeAsTransactional(block: () -> R): R {
        return block()
    }
}

Usage:

@Service
class SomeService(private val transactionalUtils: TransactionalUtils) {

    fun foo() {
        transactionalUtils.executeAsTransactional { transactionalFoo() }
    }

    private fun transactionalFoo() {
        println("This method is executed within transaction")
    }
}

Don't know whether TransactionTemplate reuse existing transaction or not but this code definitely do.

if you want to use str outside looop also; declare it outside. otherwise, 2nd version is fine.

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

Source: http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

Use the following

1.) Choose the image you want to set in your title bar.
2.) Convert it to ".ico" format. (You can use the following link online) http://image.online-convert.com/convert-to-ico
3.) Save the file as "favicon.ico" in the same folder as your .html file
4.) Add this inside your head tag <link rel="shortcut icon" href="favicon.ico"/>

You can find out what Git does with a file by seeing what it does when you add it to the index. The index is like a pre-commit. With the index committed, you can use git checkout to bring everything that was in the index back into the working directory. So, what does Git do when you add a symbolic link to the index?

To find out, first, make a symbolic link:

$ ln -s /path/referenced/by/symlink symlink

Git doesn't know about this file yet. git ls-files lets you inspect your index (-s prints stat-like output):

$ git ls-files -s ./symlink
[nothing]

Now, add the contents of the symbolic link to the Git object store by adding it to the index. When you add a file to the index, Git stores its contents in the Git object store.

$ git add ./symlink

So, what was added?

$ git ls-files -s ./symlink
120000 1596f9db1b9610f238b78dd168ae33faa2dec15c 0       symlink

The hash is a reference to the packed object that was created in the Git object store. You can examine this object if you look in .git/objects/15/96f9db1b9610f238b78dd168ae33faa2dec15c in the root of your repository. This is the file that Git stores in the repository, that you can later check out. If you examine this file, you'll see it is very small. It does not store the contents of the linked file. To confirm this, print the contents of the packed repository object with git cat-file:

$ git cat-file -p 1596f9db1b9610f238b78dd168ae33faa2dec15c
/path/referenced/by/symlink

(Note 120000 is the mode listed in ls-files output. It would be something like 100644 for a regular file.)

But what does Git do with this object when you check it out from the repository and into your filesystem? It depends on the core.symlinks config. From man git-config:

core.symlinks

If false, symbolic links are checked out as small plain files that contain the link text.

So, with a symbolic link in the repository, upon checkout you either get a text file with a reference to a full filesystem path, or a proper symbolic link, depending on the value of the core.symlinks config.

Either way, the data referenced by the symlink is not stored in the repository.

Another way-too-complicated workaround, with the benefit of not having to re-install the application as the previous workaround required. This requires that you have access to the msi (or a setup.exe with the msi embedded).

If you have Visual Studio 2012 (or possibly other editions) and install the free "InstallShield LE", then you can create a new setup project using InstallShield.

One of the configuration options in the "Organize your Setup" step is called "Upgrade Paths". Open the properties for Upgrade Paths, and in the left pane right click "Upgrade Paths" and select "New Upgrade Path" ... now browse to the msi (or setup.exe containing the msi) and click "open". The upgrade code will be populated for you in the settings page in the right pane which you should now see.

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

None of these answers mention the colClasses argument which is another way to specify the variable classes in read.csv.

 stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "numeric") # all variables to numeric

or you can specify which columns to convert:

stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = c("PTS" = "numeric", "MP" = "numeric") # specific columns to numeric

Note that if a variable can't be converted to numeric then it will be converted to factor as default which makes it more difficult to convert to number. Therefore, it can be advisable just to read all variables in as 'character' colClasses = "character" and then convert the specific columns to numeric once the csv is read in:

stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "character")
point <- as.numeric(stuckey$PTS)
time <- as.numeric(stuckey$MP)

If you want to add item to the beginning of the collection you can use prepend:

$item->prepend($product, 'key');

A rather roundabout way, just for completeness:

 for /f "delims=" %i in ('type CON') do set inp=%i

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

I am using rails 4.0 and ran into the same problem

Here is my solution that passed test

add to Gemfile

gem 'bootstrap-sass'

run

bundle install

then add to app/assets/javascripts/application.js

//= require bootstrap

Then the dropdown should work

By the way, Chris's solution also work for me.

But I think it is less conform to the asset pipeline idea

This worked for me:

mv xyz.war ./tmp
cd tmp
jar -xvf xyz.war
rm -rf WEB-INF/lib/zookeeper-3.4.10.jar
rm -rf xyz.war
jar -cvf xyz.war *
mv xyz.war ../
cd ..

I know this is an old question, but as long as the dates are >= 01-Jan-1753 I use:

DATEDIFF(MONTH, DATEADD(DAY,-DAY(@Start)+1,@Start),DATEADD(DAY,-DAY(@Start)+1,@End))

Is this even possible?
You are combining two integers. They both have the range -2,147,483,648 to 2,147,483,647 but you will only take the positives. That makes 2147483647^2 = 4,61169E+18 combinations. Since each combination has to be unique AND result in an integer, you'll need some kind of magical integer that can contain this amount of numbers.

Or is my logic flawed?

On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.

EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .

None of the Win32 ports of Unix which that I could find on the Internet are satistactory, because they all have one or more of these shortcomings:

• No support for Windows PATHEXT variable. (Which defines the list of extensions implicitely added to each command before scanning the path, and in which order.) (I use a lot of tcl scripts, and no publicly available which tool could find them.)
• No support for cmd.exe code pages, which makes them display paths with non-ascii characters incorrectly. (I'm very sensitive to that, with the ç in my first name :-))
• No support for the distinct search rules in cmd.exe and the PowerShell command line. (No publicly available tool will find .ps1 scripts in a PowerShell window, but not in a cmd window!)

So I eventually wrote my own which, that suports all the above correctly.

Available there: http://jf.larvoire.free.fr/progs/which.exe

You also can use itemgetter operator:

from operator import itemgetter
my_tuples = [('c','r'), (2, 3), ('e'), (True, False),('text','sample')]
map(itemgetter(0), my_tuples)

You had better make new project with any name , then use appcompat_v7 that program make new .

Right Click Project-> properties->Android

In the section library Add and choose library appcompat.

Google Guava Libraries collection provides such function:

Iterator<String> it = Iterators.forArray(array);

One should prefere Guava over the Apache Collection (which seems to be abandoned).

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams> and you are passing var model = tm.Name.ToList(); name list. You have to pass list of Teams.

You have to pass following model

var model = new List<Teams>();

model.Add(new Teams { Name =  new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name =  new List<string>(){"John","XYZ"} });
return View(model);

The pythonic way of doing this is using subprocess.Popen

subprocess.Popen takes a list where the first element is the command to be run followed by any command line arguments.

As an example:

import subprocess

args = ['echo', 'Hello!']
subprocess.Popen(args) // same as running `echo Hello!` on cmd line

args2 = ['echo', '-v', '"Hello Again"']
subprocess.Popen(args2) // same as running 'echo -v "Hello Again!"` on cmd line

It seems that you'll need two fields, a choice list for the currency and a number field for the value.

A common technique in such case is to use a div or span for the display (form fields offscreen), and on click switch to the form elements for editing.

If

(1) you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()

    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    @RenderSection("scripts", required: false)
</html>

(2) you have Contacts.cshtml

@section Scripts{
    <script type="text/javascript" src="~/lib/contacts.js"></script>

}
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

(3) you have About.cshtml

<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

On you layout page, if required is set to false "@RenderSection("scripts", required: false)", When page renders and user is on about page, the contacts.js doesn't render.

    <html>
        <body><div>About<div>             
        </body>
        <script type="text/javascript" src="~/lib/layout.js"></script>
    </html>

if required is set to true "@RenderSection("scripts", required: true)", When page renders and user is on ABOUT page, the contacts.js STILL gets rendered.

<html>
    <body><div>About<div>             
    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    <script type="text/javascript" src="~/lib/contacts.js"></script>
</html>

IN SHORT, when set to true, whether you need it or not on other pages, it will get rendered anyhow. If set to false, it will render only when the child page is rendered.

Double perValue = 96.57;

Solved my purpose.

For Windows 10: Go to the Sql Management Studio Icon, or Short Cut in the menu: Right Click > Select Open File Location

Hold Shift and right Click the shortcut, or ssms.exe file that is in the folder. Holding shift will give you an extra option "Run as different user":

This will pop up a login box and you can type the credentials you would like your session to run under.

NetBeans, Context-Click

In NetBeans 8 with a Maven-driven project, merely context-click on the jar file list item of the dependency in which you are interested. Choose Download Sources. Wait a moment and NetBeans will automatically download and install the source code, if available.

Similarly you can choose Download Javadoc to get the doc locally installed. Then you can context-click some code in the editor and choose to see the JavaDoc.

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

you can use nawk

$ nawk '/-X/{print}' file

Short answer: You can't.

Long answer: You can use the INFORMATION_SCHEMA to get the table definitions and use this to generate the necessary UPDATE statements dynamically. For example you could start with this:

SELECT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = 'your_schema'

I'd try to avoid doing this though if at all possible.

Another trick for getting sequential pieces (beyond the seq solution already mentioned) is to use a short logical vector and use vector recycling:

foo[ c( rep(FALSE, 5), TRUE ) ]

Don't use cat as some have mentioned here. cat is a program while echo and printf are bash (shell) builtins. Launching a program or another script (also mentioned above) means to create a new process with all its costs. Using builtins, writing functions is quite cheap, because there is no need to create (execute) a process (-environment).

The opener asks "is there any standard tool to output (pipe) to stderr", the short answer is : NO ... why? ... redirecting pipes is an elementary concept in systems like unix (Linux...) and bash (sh) builds up on these concepts.

I agree with the opener that redirecting with notations like this: &2>1 is not very pleasant for modern programmers, but that's bash. Bash was not intended to write huge and robust programs, it is intended to help the admins to get there work with less keypresses ;-)

And at least, you can place the redirection anywhere in the line:

$ echo This message >&2 goes to stderr 
This message goes to stderr

You can either

1) Declare printMenu(), getUserchoice() and input as static

OR

2) If you want to design it better, move the logic from your main into a separate instance method. And then from the main create a new instance of your class and call your instance method(s)

I've found that you cannot set a gradient with background-color.

This works:

background:linear-gradient(to right, rgba(255,0,0,0), rgba(255,255,255,1));

This doesn't:

background-color:linear-gradient(to right, rgba(255,0,0,0), rgba(255,255,255,1));

What is the difference between c++ and visaul c++?

Visual C++ is an IDE. There's also C++Builder from Embarcadero. (Used to be Borland.) There are also a few other C++ IDE's.

I know that c++ has the portability and all so if you know c++ how is it related to visual c++?

C++ is as portable as the libraries that you use in your C++ application. VC++ has some specialized libraries to use with Windows, so if you use those libraries in your C++ application, you're stuck with Windows. But a simple "Hello, World" application that just uses the console as output can be compiled on Windows, Linux, VMS, AS/400, Smartphones, FreeBSD, MS-DOS, CP80 and almost any other system for which you can find a C++ compiler. Injteresting fact: at http://nethack.org/ you can download the C sourcecode for an almost antique game, where you have to walk through a bunch of mazes, kick some monsters around, find treasures and steal some valuable amulet and bring that amulet back out. (It's also a game where you can encounter your characters from previous, failed attempts to get that amulet. :-) The sourcecode of NetHack is a fine example of how portable C (C++) code can be.

Is visual c++ mostly for online apps?

No. But it can be used for online apps. Actually, C# is used more often for server-side web applications while C++ (VC++) is used for all kinds of (server) components that your application will be depending upon.

Would visual basic be better for desktop applications?

Or Embarcadero Delphi. Delphi and Basic are languages that are easier to learn than C++ and both have very good IDE's to develop GUI applications with. Unfortunately, Visual Basic is now running on .NET only, while there are still many developers who need to create WIN32 applications. Those developers often have to choose between Delphi or C++ or else convince management to move to .NET development.

You can avoid the unpleasant looking try/catch or regex by using the Scanner class:

String input = "123";
Scanner sc = new Scanner(input);
if (sc.hasNextInt())
    System.out.println("an int: " + sc.nextInt());
else {
    //handle the bad input
}

for line in f

reads all file to a memory, and that can be a problem.

My offer is to change the original source by replacing stripping and checking for empty line. Because if it is not last line - You will receive at least newline character in it ('\n'). And '.strip()' removes it. But in last line of a file You will receive truely empty line, without any characters. So the following loop will not give You false EOF, and You do not waste a memory:

with open("blablabla.txt", "r") as fl_in:
   while True:
      line = fl_in.readline()

        if not line:
            break

      line = line.strip()
      # do what You want

I think this can help

function myFormatDateFunction(date, format) {
     ...
}

jQuery('input[type="date"]')                                             
    .each(function(){                                                              
        Object.defineProperty(this,'value',{                                         
          get: function() {                                   
            return myFormatDateFunction(this.valueAsDate, 'dd.mm.yyyy');      
          },                                                                         
          configurable: true,                                                        
          enumerable : true                                                          
        });                                                                          
      });                                                                                

In my specific case I seemed to have been missing the dependency

Magic:

$ git svn clone http://svn/repo/here/trunk

Git and SVN operate very differently. You need to learn Git, and if you want to track changes from SVN upstream, you need to learn git-svn. The git-svn main page has a good examples section:

$ git svn --help

In Python:

• Instance methods: require the self argument.
• Class methods: take the class as a first argument.
• Static methods: do not require either the instance (self) or the class (cls) argument.

__init__ is a special function and without overriding __new__ it will always be given the instance of the class as its first argument.

An example using the builtin classmethod and staticmethod decorators:

import sys

class Num:
    max = sys.maxint

    def __init__(self,num):
        self.n = num

    def getn(self):
        return self.n

    @staticmethod
    def getone():
        return 1

    @classmethod
    def getmax(cls):
        return cls.max

myObj = Num(3)
# with the appropriate decorator these should work fine
myObj.getone()
myObj.getmax()
myObj.getn()

That said, I would try to use @classmethod/@staticmethod sparingly. If you find yourself creating objects that consist of nothing but staticmethods the more pythonic thing to do would be to create a new module of related functions.

First, you can always grab the current time by

var currentTime = new Date();

Then you could check out this "pretty date" example at http://www.zachleat.com/Lib/jquery/humane.js

If that doesn't work for you, just google "javascript pretty date" and you'll find dozens of example scripts.

Good luck.

Unfortunately, there is no really simple solution. You can try something like that:

Stream s1, s2;
byte[] buffer = new byte[4096];
int bytesRead = 0;
while (bytesRead = s1.Read(buffer, 0, buffer.Length) > 0) s2.Write(buffer, 0, bytesRead);
s1.Close(); s2.Close();

But the problem with that that different implementation of the Stream class might behave differently if there is nothing to read. A stream reading a file from a local harddrive will probably block until the read operaition has read enough data from the disk to fill the buffer and only return less data if it reaches the end of file. On the other hand, a stream reading from the network might return less data even though there are more data left to be received.

Always check the documentation of the specific stream class you are using before using a generic solution.

For Bootstrap 2 Auto adjust model height dynamically

  //Auto adjust modal height on open 
  $('#modal').on('shown',function(){
     var offset = 0;
     $(this).find('.modal-body').attr('style','max-height:'+($(window).height()-offset)+'px !important;');
  });

Here is a solution that defines a git alias, so you will be able use it like that :

git rblame -M -n -L '/REGEX/,+1' FILE

Output example :

00000000 18 (Not Committed Yet 2013-08-19 13:04:52 +0000 728) fooREGEXbar
15227b97 18 (User1 2013-07-11 18:51:26 +0000 728) fooREGEX
1748695d 23 (User2 2013-03-19 21:09:09 +0000 741) REGEXbar

You can define the alias in your .gitconfig or simply run the following command

git config alias.rblame !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); echo $line; done' dumb_param

This is an ugly one-liner, so here is a de-obfuscated equivalent bash function :

git-rblame () {
    local commit line
    while line=$(git blame "$@" $commit 2>/dev/null); do
        commit="${line:0:8}^"
        if [ "00000000^" == "$commit" ]; then
            commit=$(git rev-parse HEAD)
        fi
        echo $line
    done
}

The pickaxe solution ( git log --pickaxe-regex -S'REGEX' ) will only give you line additions/deletions, not the other alterations of the line containing the regular expression.

A limitation of this solution is that git blame only returns the 1st REGEX match, so if multiple matches exist the recursion may "jump" to follow another line. Be sure to check the full history output to spot those "jumps" and then fix your REGEX to ignore the parasite lines.

Finally, here is an alternate version that run git show on each commit to get the full diff :

git config alias.rblameshow !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); git show $commit; done' dumb_param

Logical nullish assignment, ES2020+ solution

New operators are currently being added to the browsers, ??=, ||=, and &&=. This post will focus on ??=.

This checks if left side is undefined or null, short-circuiting if already defined. If not, the right-side is assigned to the left-side variable.

Comparing Methods

// Using ??=
name ??= "Dave"

// Previously, ES2020
name = name ?? "Dave"

// Before that (not equivalent, but commonly used)
name = name || "Dave" // name ||= "Dave"

Basic Examples

let a       // undefined
let b = null
let c = false

a ??= true  // true
b ??= true  // true
c ??= true  // false

// Equivalent to
a = a ?? true

Object/Array Examples

let x = ["foo"]
let y = { foo: "fizz" }

x[0] ??= "bar"  // "foo"
x[1] ??= "bar"  // "bar"

y.foo ??= "buzz"  // "fizz"
y.bar ??= "buzz"  // "buzz"

x  // Array [ "foo", "bar" ]
y  // Object { foo: "fizz", bar: "buzz" }

While other answers were usable, this really helped me, so I am putting it also here.

From the documentation:

Instead of specifying a context, you can pass a single Dockerfile in the URL or pipe the file in via STDIN. To pipe a Dockerfile from STDIN:

$ docker build - < Dockerfile

With Powershell on Windows, you can run:

Get-Content Dockerfile | docker build -

When the build is done, run command:

docker image ls

You will see something like this:

REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE
<none>                     <none>              123456789        39 seconds ago      422MB

Copy your actual IMAGE ID and then run

docker run 123456789

Where the number at the end is the actual Image ID from previous step

If you do not want to remember the image id, you can tag your image by

docker tag 123456789 pavel/pavel-build

Which will tag your image as pavel/pavel-build

GridView does not act as column names, as that's it's datasource property to know those things.

If you still need to know the index given a column name, then you can create a helper method to do this as the gridview Header normally contains this information.

int GetColumnIndexByName(GridViewRow row, string columnName)
{
    int columnIndex = 0;
    foreach (DataControlFieldCell cell in row.Cells)
    {
        if (cell.ContainingField is BoundField)
            if (((BoundField)cell.ContainingField).DataField.Equals(columnName))
                break;
        columnIndex++; // keep adding 1 while we don't have the correct name
    }
    return columnIndex;
}

remember that the code above will use a BoundField... then use it like:

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int index = GetColumnIndexByName(e.Row, "myDataField");
        string columnValue = e.Row.Cells[index].Text;
    }
}

I would strongly suggest that you use the TemplateField to have your own controls, then it's easier to grab those controls like:

<asp:GridView ID="gv" runat="server">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

and then use

string columnValue = ((Label)e.Row.FindControl("lblName")).Text;

The error:

is occurring because the current SDK version is incompatible with Java 9.

So, to solve it, you can downgrade your java version to Java 8, or with a workaround, you can export the following option on your terminal:

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

And to make it stick, you can export the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add as an environment permanently on Windows.

Then, you can type the flutter or sdkmanager command:

Flutter:

flutter doctor --android-licenses

sdkmanager:

sdkmanager --licenses

and type Y when needed to accept the licenses.

ps. This doesn't work for Java 11/11+, which doesn't have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

You could also use wp_list_categories();

wp_list_categories( array('taxonomy' => 'product_cat', 'title_li'  => '') );

You can't do that because you can not know the salt at a precise time. Below, a code who works in theory (not tested for the syntaxe)

<?php
$password1 = $_POST['password'];
$salt      = 'hello_1m_@_SaLT';
$hashed    = hash('sha256', $password1 . $salt);
?>

When you insert :

$qry="INSERT INTO member VALUES('$username', '$hashed')";

And for retrieving user :

$qry="SELECT * FROM member WHERE username='$username' AND password='$hashed'";

  }

For the current Spring-Boot Version 1.5.3 the parameter is

spring.resources.static-locations

Update I configured

`spring.resources.static-locations=file:/opt/x/y/z/static``

and expected to get my index.html living in this folder when calling

http://<host>/index.html

This did not work. I had to include the folder name in the URL:

http://<host>/static/index.html

Thanks for the pointers.

I don't know, whether this is the best approach to the problem or not, but here is how I got it to work. I referenced the Microsoft XML, v2.6 dll in my VBA, and then the following code snippet, gives me the required values

Dim objXML As MSXML2.DOMDocument

Set objXML = New MSXML2.DOMDocument

If Not objXML.loadXML(strXML) Then  'strXML is the string with XML'
    Err.Raise objXML.parseError.ErrorCode, , objXML.parseError.reason
End If
 
Dim point As IXMLDOMNode
Set point = objXML.firstChild

Debug.Print point.selectSingleNode("X").Text
Debug.Print point.selectSingleNode("Y").Text

One way, which seems reliable (though tested only in Firefox and Chrome) is to use JavaScript to listen for the animationend (or its camelCased, and prefixed, sibling animationEnd) event, and apply a short-lived (in the demo 0.01 second) animation to the element-type you plan to add. This, of course, is not an onCreate event, but approximates (in compliant browsers) an onInsertion type of event; the following is a proof-of-concept:

$(document).on('webkitAnimationEnd animationend MSAnimationEnd oanimationend', function(e){
    var eTarget = e.target;
    console.log(eTarget.tagName.toLowerCase() + ' added to ' + eTarget.parentNode.tagName.toLowerCase());
    $(eTarget).draggable(); // or whatever other method you'd prefer
});

With the following HTML:

<div class="wrapper">
    <button class="add">add a div element</button>
</div>

And (abbreviated, prefixed-versions-removed though present in the Fiddle, below) CSS:

/* vendor-prefixed alternatives removed for brevity */
@keyframes added {
    0% {
        color: #fff;
    }
}

div {
    color: #000;
    /* vendor-prefixed properties removed for brevity */
    animation: added 0.01s linear;
    animation-iteration-count: 1;
}

JS Fiddle demo.

Obviously the CSS can be adjusted to suit the placement of the relevant elements, as well as the selector used in the jQuery (it should really be as close to the point of insertion as possible).

Documentation of the event-names:

Mozilla   |  animationend
Microsoft |  MSAnimationEnd
Opera     |  oanimationend
Webkit    |  webkitAnimationEnd
W3C       |  animationend

log4j does not support this directly.

As you do not want a configuration file, you most likely use programmatic configuration. I would suggest that you look into scanning all the system properties, and explicitly program what you want based on this.

This script works only on the path names. It does not require any of the files to exist. If the paths passed are not absolute, the behavior is a bit unusual, but it should work as expected if both paths are relative.

TO collect all item of an array and return a json object

collectData: function (arrayElements) {

        var main = [];

        for (var i = 0; i < arrayElements.length; i++) {
            var data = {};
            this.e = arrayElements[i];            
            data.text = arrayElements[i].text;
            data.val = arrayElements[i].value;
            main[i] = data;
        }
        return main;
    },

TO parse the same data we go through like this

dummyParse: function (json) {       
        var o = JSON.parse(json); //conerted the string into JSON object        
        $.each(o, function () {
            inner = this;
            $.each(inner, function (index) {
                alert(this.text)
            });
        });

}

Just set the style:

var menu = document.createElement("select");
menu.style.width = "100px";

Or if you like, you can use jQuery:

$(menu).css("width", "100px");

Assuming you are referring to Django's Auth User, in your view:

def game(request):
  user = request.user

  gta = Game.objects.create(name="gta", owner=user)

'<option value="' + col + '"'+ (col === "screwdriver" ? " selected " : "") +'>Very roomy</option>';

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

If you are developing an OSGi system I would recommend you to download the "bundlefied" version from Springsource Enterprise Bundle Repository.

Otherwise its ok to use a regular jar-file containing the javax.persistence package

When you pass a string to the filter function, the string is interpreted as SQL. Count is a SQL keyword and using count as a variable confuses the parser. This is a small bug (you can file a JIRA ticket if you want to).

You can easily avoid this by using a column expression instead of a String:

df.groupBy("x").count()
  .filter($"count" >= 2)
  .show()

From the link Jweede posted:

exception socket.timeout:

This exception is raised when a timeout occurs on a socket
which has had timeouts enabled via a prior call to settimeout().
The accompanying value is a string whose value is currently
always “timed out”.

Here are the demo server and client programs for the socket module from the python docs

# Echo server program
import socket

HOST = ''                 # Symbolic name meaning all available interfaces
PORT = 50007              # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
    data = conn.recv(1024)
    if not data: break
    conn.send(data)
conn.close()

And the client:

# Echo client program
import socket

HOST = 'daring.cwi.nl'    # The remote host
PORT = 50007              # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
s.send('Hello, world')
data = s.recv(1024)
s.close()
print 'Received', repr(data)

On the docs example page I pulled these from, there are more complex examples that employ this idea, but here is the simple answer:

Assuming you're writing the client program, just put all your code that uses the socket when it is at risk of being dropped, inside a try block...

try:
    s.connect((HOST, PORT))
    s.send("Hello, World!")
    ...
except socket.timeout:
    # whatever you need to do when the connection is dropped

• Short version of (correct) tzaman answer will be (for fresh SVN)

  svn switch ^/branches/v1p2p3
  

• --relocate switch is deprecated anyway, when it needed you'll have to use svn relocate command

• Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)

On Windows, the caret character (^) must be escaped:

svn switch ^^/branches/v1p2p3

Here is another way:

df['rnd'] = np.random.rand(len(df)) df = df.sort_values(by='rnd', inplace=True).drop('rnd', axis=1)

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

Another cause of "TCP ACKed Unseen" is the number of packets that may get dropped in a capture. If I run an unfiltered capture for all traffic on a busy interface, I will sometimes see a large number of 'dropped' packets after stopping tshark.

On the last capture I did when I saw this, I had 2893204 packets captured, but once I hit Ctrl-C, I got a 87581 packets dropped message. Thats a 3% loss, so when wireshark opens the capture, its likely to be missing packets and report "unseen" packets.

As I mentioned, I captured a really busy interface with no capture filter, so tshark had to sort all packets, when I use a capture filter to remove some of the noise, I no longer get the error.

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

In short, @classmethod turns a normal method to a factory method.

Let's explore it with an example:

class PythonBook:
    def __init__(self, name, author):
        self.name = name
        self.author = author
    def __repr__(self):
        return f'Book: {self.name}, Author: {self.author}'

Without a @classmethod,you should labor to create instances one by one and they are scattered.

book1 = PythonBook('Learning Python', 'Mark Lutz')
In [20]: book1
Out[20]: Book: Learning Python, Author: Mark Lutz
book2 = PythonBook('Python Think', 'Allen B Dowey')
In [22]: book2
Out[22]: Book: Python Think, Author: Allen B Dowey

As for example with @classmethod

class PythonBook:
    def __init__(self, name, author):
        self.name = name
        self.author = author
    def __repr__(self):
        return f'Book: {self.name}, Author: {self.author}'
    @classmethod
    def book1(cls):
        return cls('Learning Python', 'Mark Lutz')
    @classmethod
    def book2(cls):
        return cls('Python Think', 'Allen B Dowey')

Test it:

In [31]: PythonBook.book1()
Out[31]: Book: Learning Python, Author: Mark Lutz
In [32]: PythonBook.book2()
Out[32]: Book: Python Think, Author: Allen B Dowey

See? Instances are successfully created inside a class definition and they are collected together.

In conclusion, @classmethod decorator convert a conventional method to a factory method,Using classmethods makes it possible to add as many alternative constructors as necessary.

If you don't want it using position fixed, and following you annoyingly on mobile, this seems to be working for me so far.

html {
    min-height: 100%;
    position: relative;
}

#site-footer {
    position: absolute;
    bottom: 0;
    left: 0;
    width: 100%;
    padding: 6px 2px;
    background: #32383e;
}

Just set the html to min-height: 100%; and position: relative;, then position: absolute; bottom: 0; left: 0; on the footer. I then made sure the footer was the last element in the body.

Let me know if this doesn't work for anyone else, and why. I know these tedious style hacks can behave strangely among various circumstances I'd not thought of.

I fully agree with the vector way when implementing a dynamic array. However, bear in mind that STL provides you with a host of containers that cater to different runtime requirements.You should choose one with care. E.g: For fast insertion at back you have the choice between a vector and a deque.

And I almost forgot, with great power comes great responsibility :-) Since vectors are flexible in size, they often reallocate automagically to adjust for adding elements.So beware about iterator invalidation (yes, it applies as well to pointers). However, as long as you are using operator[] for accessing the individual elements you are safe.

The answer to this may depend largely on the UUID version.

Many UUID generators use a version 4 random number. However, many of these use Pseudo a Random Number Generator to generate them.

If a poorly seeded PRNG with a small period is used to generate the UUID I would say it's not very safe at all. Some random number generators also have poor variance. i.e. favouring certain numbers more often than others. This isn't going to work well.

Therefore, it's only as safe as the algorithms used to generate it.

On the flip side, if you know the answer to these questions then I think a version 4 uuid should be very safe to use. In fact I'm using it to identify blocks on a network block file system and so far have not had a clash.

In my case, the PRNG I'm using is a mersenne twister and I'm being careful with the way it's seeded which is from multiple sources including /dev/urandom. Mersenne twister has a period of 2^19937 - 1. It's going to be a very very long time before I see a repeat uuid.

So pick a good library or generate it yourself and make sure you use a decent PRNG algorithm.

Once I updated my Java version to 8 as suggested by browser. However I had selected to uninstall previous Java 6 version I have been used for coding my projects. When I enter the command in "java -version" in cmd it showed 1.8 and I could not start eclipse IDE run on Java 1.6.

When I installed Java 8 update for the browser it had changed the "PATH" System variable appending "C:\ProgramData\Oracle\Java\javapath" to the beginning. Newly added path pointed to Java vesion 8. So I removed that path from "PATH" System variable and everything worked fine. :)

I normally test by running the job i created like this:

It is easier to use two terminals to do this.

run job:

#./jobname.sh

go to:

#/var/log and run 

run the following:

#tailf /var/log/cron

This allows me to see the cron logs update in real time. You can also review the log after you run it, I prefer watching in real time.

Here is an example of a simple cron job. Running a yum update...

#!/bin/bash
YUM=/usr/bin/yum
$YUM -y -R 120 -d 0 -e 0 update yum
$YUM -y -R 10 -e 0 -d 0 update

Here is the breakdown:

First command will update yum itself and next will apply system updates.

-R 120 : Sets the maximum amount of time yum will wait before performing a command

-e 0 : Sets the error level to 0 (range 0 - 10). 0 means print only critical errors about which you must be told.

-d 0 : Sets the debugging level to 0 - turns up or down the amount of things that are printed. (range: 0 - 10).

-y : Assume yes; assume that the answer to any question which would be asked is yes

After I built the cron job I ran the below command to make my job executable.

#chmod +x /etc/cron.daily/jobname.sh 

Hope this helps, Dorlack

the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)

=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679

So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)

You can define a Multi-module project structure, then you can set the configuration for sonar in one properties file in the root folder of your project, (Way #1)

The "overhead" with cursors is merely part of the API. Cursors are how parts of the RDBMS work under the hood. Often CREATE TABLE and INSERT have SELECT statements, and the implementation is the obvious internal cursor implementation.

Using higher-level "set-based operators" bundles the cursor results into a single result set, meaning less API back-and-forth.

Cursors predate modern languages that provide first-class collections. Old C, COBOL, Fortran, etc., had to process rows one at a time because there was no notion of "collection" that could be used widely. Java, C#, Python, etc., have first-class list structures to contain result sets.

The Slow Issue

In some circles, the relational joins are a mystery, and folks will write nested cursors rather than a simple join. I've seen truly epic nested loop operations written out as lots and lots of cursors. Defeating an RDBMS optimization. And running really slowly.

Simple SQL rewrites to replace nested cursor loops with joins and a single, flat cursor loop can make programs run in 100th the time. [They thought I was the god of optimization. All I did was replace nested loops with joins. Still used cursors.]

This confusion often leads to an indictment of cursors. However, it isn't the cursor, it's the misuse of the cursor that's the problem.

The Size Issue

For really epic result sets (i.e., dumping a table to a file), cursors are essential. The set-based operations can't materialize really large result sets as a single collection in memory.

Alternatives

I try to use an ORM layer as much as possible. But that has two purposes. First, the cursors are managed by the ORM component. Second, the SQL is separated from the application into a configuration file. It's not that the cursors are bad. It's that coding all those opens, closes and fetches is not value-add programming.

An short and easy way to change color of option menu index icon is:

<!-- android:textColorSecondary is the color of the menu overflow icon (three vertical dots) -->
<item name="android:textColorSecondary">@color/optionMenuIconColor</item>

Add above line of code into style.xml (custom theme) file, Hope you get answer,Thanks.

Your class's constructor method should be called __construct(), not __constructor():

public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}

Why do people keep confusing php and javascript?

PHP is SERVER SIDE
JAVASCRIPT (like onclick) is CLIENT SIDE

You will have to use just javascript to redirect. Otherwise if you want PHP involved you can use an AJAX call to log a hit or whatever you like to send back a URL or additional detail.

To change transparency on an svg code the simplest way is to open it on any text editor and look for the style attributes. It depends on the svg creator the way the styles are displayed. As i am an Inkscape user the usual way it set the style values is through a style tag just as if it were html but using svg native attributes like fill, stroke, stroke-width, opacity and so on. opacity affects the whole svg object, or path or group in which its stated and fill-opacity, stroke-opacity will affect just the fill and the stroke transparency. That said, I have also used and tasted to just use fill and instead of using#fff use instead the rgba standard like this rgba(255, 255, 255, 1) just as in css. This works fine for must modern browsers.

Keep in mind that if you intend to further reedit your svg the best practice, in my experience, is to always keep an untouched version at hand. Inkscape is more flexible with hand changed svgs but Illustrator and CorelDraw may have issues importing and edited svg.

Notice that in the last example the fill-opacity has been removed as rgba standard covers both color and alpha channel.

Alter table table_name modify table_name.column_name data_type AUTO_INCREMENT;

eg:

Alter table avion modify avion.av int AUTO_INCREMENT;

If you want to remove all - you can use:

.replace(new RegExp('-', 'g'),"")

Using forward declarations instead of a full #includes is possible only when you are not intending on using the type itself (in this file's scope) but a pointer or reference to it.

To use the type itself, the compiler must know its size - hence its full declaration must be seen - hence a full #include is needed.

However, the size of a pointer or reference is known to the compiler, regardless of the size of the pointee, so a forward declaration is sufficient - it declares a type identifier name.

Interestingly, when using pointer or reference to class or struct types, the compiler can handle incomplete types saving you the need to forward declare the pointee types as well:

// header.h

// Look Ma! No forward declarations!
typedef class A* APtr; // class A is an incomplete type - no fwd. decl. anywhere
typedef class A& ARef;

typedef struct B* BPtr; // struct B is an incomplete type - no fwd. decl. anywhere
typedef struct B& BRef;

// Using the name without the class/struct specifier requires fwd. decl. the type itself.    
class C;         // fwd. decl. type
typedef C* CPtr; // no class/struct specifier 
typedef C& CRef; // no class/struct specifier 

struct D;        // fwd. decl. type
typedef D* DPtr; // no class/struct specifier 
typedef D& DRef; // no class/struct specifier 

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

usually i don't use for loop in R, but here is my solution using for loops and two packages : plyr and dostats

plyr is on cran and you can download dostats on https://github.com/halpo/dostats (may be using install_github from Hadley devtools package)

Assuming that i have your first two data.frame (Df.1 and Df.2) in csv files, you can do something like this.

require(plyr)
require(dostats)

files <- list.files(pattern = ".csv")


for (i in seq_along(files)) {

    assign(paste("Df", i, sep = "."), read.csv(files[i]))

    assign(paste(paste("Df", i, sep = ""), "summary", sep = "."), 
           ldply(get(paste("Df", i, sep = ".")), dostats, sum, min, mean, median, max))

}

Here is the output

R> Df1.summary
  .id sum min   mean median max
1   A  34   4 5.6667    5.5   8
2   B  22   1 3.6667    3.0   9
R> Df2.summary
  .id sum min   mean median max
1   A  21   1 3.5000    3.5   6
2   B  16   1 2.6667    2.5   5

Here is how I did mine: if you use npx create-react-app to set up you react, you need to import the image from its folder in the Component where you want to use it. It's just the way you import other modules from their folders.

So, you need to write:

import myImage from './imageFolder/imageName'

Then in your JSX, you can have something like this: <image src = {myImage} />

See it in the screenshot below:

There is also this way of specifying the viewmodel:

using Wpf = System.Windows;

public partial class App : Wpf.Application //your skeleton app already has this.
{
    protected override void OnStartup( Wpf.StartupEventArgs e ) //you need to add this.
    {
        base.OnStartup( e );
        MainWindow = new MainView();
        MainWindow.DataContext = new MainViewModel( e.Args );
        MainWindow.Show();
    }
}

<Rant>

All of the solutions previously proposed require that MainViewModel must have a parameterless constructor.

Microsoft is under the impression that systems can be built using parameterless constructors. If you are also under that impression, go ahead and use some of the other solutions.

For those that know that constructors must have parameters, and therefore the instantiation of objects cannot be left in the hands of magic frameworks, the proper way of specifying the viewmodel is the one I showed above.

</Rant>

You could use

Character.isWhitespace(c)

or any of the other available methods in the Character class.

  if (c == ' ')

also works.

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

If you don't want to duplicate code, and like me you just want to show stats, in your view model, you could just pass in the models you want to get data from like so:

public class GameViewModel
{
    public virtual Ship Ship { get; set; }
    public virtual GamePlayer GamePlayer { get; set; }     
}

Then, in your controller just run your queries on the respective models, pass them to the view model and return it, example:

GameViewModel PlayerStats = new GameViewModel();

GamePlayer currentPlayer = (from c in db.GamePlayer [more queries]).FirstOrDefault();

[code to check if results]

//pass current player into custom view model
PlayerStats.GamePlayer = currentPlayer;

Like I said, you should only really do this if you want to display stats from the relevant tables, and there's no other part of the CRUD process happening, for security reasons other people have mentioned above.

something like....

SELECT f.*
      ,a1.city as from
      ,a2.city as to
FROM flights f
INNER JOIN airports a1
ON f.fairport = a1. code
INNER JOIN airports a2
ON f.tairport = a2. code

I was also facing the same issue, tried all the solutions mentioned in the answer but none seemed to work. Turned out that during the checkin of code to TFS. TFS did not checkin the Resx file it only checked in the designer file. So all other developers were facing this issue while running on their machines. Checking in the resx file manually did the trick

You have to define the text color in the layout *simple_list_item_1* that defines the layout of each of your items.

You set the background color of the LinearLayout and not of the ListView. The background color of the child items of the LinearLayout are transparent by default (in most cases).

And you set the black text color for the TextView that is not part of your ListView. It is an own item (child item of the LinearLayout) here.

numpy.ndarray can contain any type of element, e.g. int, float, string etc. Check the type an do a conversion if neccessary.

I have a scenario where I use the BannerViewController written by Apple to display my ads and a ScrollViewController embedded in the BannerViewController.

To prevent the navigation bar from hiding my content, I had to make two changes.

1) Modify BannerViewController.m

- (void)viewDidLoad
{
   [super viewDidLoad];
   float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
   if (systemVersion >= 7.0) {
      self.edgesForExtendedLayout = UIRectEdgeNone;
   }
}

2) Modify my ScrollViewContoller

- (void)viewDidLoad
{
    [super viewDidLoad];
    float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 7.0) {
        self.edgesForExtendedLayout = UIRectEdgeBottom;
    }
}

Now the ads show up correctly at the bottom of the view instead of being covered by the Navigation bar and the content on the top is not cut off.

You could do this

<?php include("Includes/styles.inc"); ?>

And then in this include file, have a link to the your css file(s).

This post has helped me a lot, and after a few iterations, this is what we use.

The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.

You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.

What you'll get:

• A plain and simple 'logThis' function that will display strings and objects along with current date and time for each line
• A dedicated window on top of everything else. (show it only when needed)
• Can be used inside '.catch' to see relevant errors from promises.
• No change of default console.log behavior
• Messages will appear in the console as well.

function logThis(message) {
  // if we pass an Error object, message.stack will have all the details, otherwise give us a string
  if (typeof message === 'object') {
    message = message.stack || objToString(message);
  }

  console.log(message);

  // create the message line with current time
  var today = new Date();
  var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
  var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
  var dateTime = date + ' ' + time + ' ';

  //insert line
  document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}

function objToString(obj) {
  var str = 'Object: ';
  for (var p in obj) {
    if (obj.hasOwnProperty(p)) {
      str += p + '::' + obj[p] + ',\n';
    }
  }
  return str;
}

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

#logWindow {
  overflow: auto;
  position: absolute;
  width: 90%;
  height: 90%;
  top: 5%;
  left: 5%;
  right: 5%;
  bottom: 5%;
  background-color: rgba(0, 0, 0, 0.5);
  z-index: 20;
}

<div id="logWindow">
  <pre id="logger"></pre>
</div>

Thanks this answer too, JSON.stringify() didn't work for this.

I think the answer is a mix of your question and this answer here: https://stackoverflow.com/a/15931345/734687 So I would try the following code:

1. change ACTION_VIEW to ACTION_SENDTO
2. set the Uri as you did
3. set the package to whatsapp

Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

I looked into the Whatsapp manifest and saw that ACTION_SEND is registered to the activity ContactPicker, so that will not help you. However ACTION_SENDTO is registered to the activity com.whatsapp.Conversation which sounds more adequate for your problem.

Whatsapp can work as a replacement for sending SMS, so it should work like SMS. When you do not specify the desired application (via setPackage) Android displays the application picker. Thererfor you should just look at the code for sending SMS via intent and then provide the additional package information.

Uri uri = Uri.parse("smsto:" + smsNumber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra("sms_body", smsText);  
i.setPackage("com.whatsapp");  
startActivity(i);

First try just to replace the intent ACTION_SEND to ACTION_SENDTO . If this does not work than provide the additional extra sms_body. If this does not work than try to change the uri.

Update I tried to solve this myself and was not able to find a solution. Whatsapp is opening the chat history, but doesn't take the text and send it. It seems that this functionality is just not implemented.

Alternative solution that doesn't use position absolute:
I see a lot of position absolute answers. I couldn't use position absolute without breaking something else. So for those that couldn't as well, here is what I did:
https://stackoverflow.com/a/58622840/6546317 (posted in response to another question).

The solution only focuses on vertically centering because my children elements were already horizontally centered but same could be applied if you couldn't horizontally center them in another way.

Just write the "include" command :

import os

def include(filename):
    if os.path.exists(filename): 
        execfile(filename)


include('myfile.py')

@Deleet :

@bfieck remark is correct, for python 2 and 3 compatibility, you need either :

Python 2 and 3: alternative 1

from past.builtins import execfile

execfile('myfile.py')

Python 2 and 3: alternative 2

exec(compile(open('myfile.py').read()))

In this simple way

char str [10] = "IAmCute";
printf ("%c",str[4]);

Try this:

            DataTable dt = new DataTable();
            int sum = 0;
            foreach (DataRow dr in dt.Rows)
            {
                foreach (DataColumn dc in dt.Columns)
                {
                    sum += (int)dr[dc];
                }
            } 

I agree with using frameworks for things like this, just because its easier. I hacked this up real quick, just fades an image out and then switches, also will not work in older versions of IE. But as you can see the code for the actual fade is much longer than the JQuery implementation posted by KARASZI István.

function changeImage() {
    var img = document.getElementById("img");
    img.src = images[x];
    x++;        
    if(x >= images.length) {
        x = 0;
    } 
    fadeImg(img, 100, true);
    setTimeout("changeImage()", 30000);
}

function fadeImg(el, val, fade) {
    if(fade === true) {
        val--;
    } else {
        val ++;
    }       
    if(val > 0 && val < 100) {
        el.style.opacity = val / 100;
        setTimeout(function(){ fadeImg(el, val, fade); }, 10);
    }
}

var images = [], x = 0;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
images[2] = "image3.jpg";
setTimeout("changeImage()", 30000);

Or use some JavaScript to change the name of the select and set it to disabled. This way the select is still submitted, but using a name you aren't checking.

Just add extra data to the Intent you use to call your activity.

In the caller activity :

Intent i = new Intent(this, TheNextActivity.class);
i.putExtra("id", id);
startActivity(i);

Inside the onCreate() of the activity you call :

Bundle b = getIntent().getExtras();
int id = b.getInt("id");

Per the MySQL docs DECLARE works only at the start of a BEGIN...END block as in a stored program.

As of Android version 4.0 official APIs and intents are available to interact with the available calendar providers.

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

In .Net Core You can use

return new ForbidResult();

instead of

return Unauthorized();

which has the advantage to redirecting to the default unauthorized page (Account/AccessDenied) rather than giving a straight 401

to change the default location modify your startup.cs

services.AddAuthentication(options =>...)
            .AddOpenIdConnect(options =>...)
            .AddCookie(options =>
            {
                options.AccessDeniedPath = "/path/unauthorized";

            })

You can use some methods of the DateTime class, which might be handy; namely, DateTime::createFromFormat() in conjunction with DateTime::getLastErrors().

$test_date = '03/22/2010';

$date = DateTime::createFromFormat('m/d/Y', $test_date);
$date_errors = DateTime::getLastErrors();
if ($date_errors['warning_count'] + $date_errors['error_count'] > 0) {
    $errors[] = 'Some useful error message goes here.';
}

This even allows us to see what actually caused the date parsing warnings/errors (look at the warnings and errors arrays in $date_errors).

This is a good summary I found:

The Carriage Return (CR) character (0x0D, \r) moves the cursor to the beginning of the line without advancing to the next line. This character is used as a new line character in Commodore and Early Macintosh operating systems (OS-9 and earlier).

The Line Feed (LF) character (0x0A, \n) moves the cursor down to the next line without returning to the beginning of the line. This character is used as a new line character in UNIX based systems (Linux, Mac OSX, etc)

The End of Line (EOL) sequence (0x0D 0x0A, \r\n) is actually two ASCII characters, a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as a new line character in most other non-Unix operating systems including Microsoft Windows, Symbian OS and others.

The thing is that decimal numbers defaults to double. And since double doesn't fit into float you have to tell explicitely you intentionally define a float. So go with:

float b = 3.6f;

There isn't a plain CSS method for this. You might have to go with JavaScript + Regex to pop in a span.

Ideally, there would be a pseudo-element for first-word, but you're out of luck as that doesn't appear to work. We do have :first-letter and :first-line.

You might be able to use a combination of :after or :before to get at it without using a span.

For PHP >= 5.3.0 use this:

$hostname = gethostname();

For PHP < 5.3.0 but >= 4.2.0 use this:

$hostname = php_uname('n');

For PHP < 4.2.0 use this:

$hostname = getenv('HOSTNAME'); 
if(!$hostname) $hostname = trim(`hostname`); 
if(!$hostname) $hostname = exec('echo $HOSTNAME');
if(!$hostname) $hostname = preg_replace('#^\w+\s+(\w+).*$#', '$1', exec('uname -a')); 

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

This is a cURL function that can send or retrieve data. It should work with any PHP app that supports OAuth:

    function jwt_request($token, $post) {

       header('Content-Type: application/json'); // Specify the type of data
       $ch = curl_init('https://APPURL.com/api/json.php'); // Initialise cURL
       $post = json_encode($post); // Encode the data array into a JSON string
       $authorization = "Authorization: Bearer ".$token; // Prepare the authorisation token
       curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization )); // Inject the token into the header
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       curl_setopt($ch, CURLOPT_POST, 1); // Specify the request method as POST
       curl_setopt($ch, CURLOPT_POSTFIELDS, $post); // Set the posted fields
       curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // This will follow any redirects
       $result = curl_exec($ch); // Execute the cURL statement
       curl_close($ch); // Close the cURL connection
       return json_decode($result); // Return the received data

    }

Use it within one-way or two-way requests:

$token = "080042cad6356ad5dc0a720c18b53b8e53d4c274"; // Get your token from a cookie or database
$post = array('some_trigger'=>'...','some_values'=>'...'); // Array of data with a trigger
$request = jwt_request($token,$post); // Send or retrieve data

Why do you have the brackets around digit? It should be

NSLog("%@", digit);

You're also missing an = in the first line...

NSString *digit = [[sender titlelabel] text];

1. You can use the FindIndex() method to find the index of item.
2. Create a new list item.
3. Override indexed item with the new item.

List<Class1> list = new List<Class1>();

int index = list.FindIndex(item => item.Number == textBox6.Text);

Class1 newItem = new Class1();
newItem.Prob1 = "SomeValue";

list[index] = newItem;

Read SVNBook | Client Credentials.

With modern SVN you can just run svn auth to display the list of cached credentials. Don't forget to make sure that you run up-to-date SVN client version because svn auth was introduced in version 1.9. The last line will specify the path to credential store which by default is %APPDATA%\Subversion\auth on Windows and ~/.subversion/auth/ on Unix-like systems.

PS C:\Users\MyUser> svn auth
------------------------------------------------------------------------
Credential kind: svn.simple
Authentication realm: <https://svn.example.local:443> VisualSVN Server
Password cache: wincrypt
Password: [not shown]
Username: user

Credentials cache in 'C:\Users\MyUser\AppData\Roaming\Subversion' contains 5 credentials

You can use this sql statement to get the history for any date:

SELECT * FROM V$SQL V where  to_date(v.FIRST_LOAD_TIME,'YYYY-MM-DD hh24:mi:ss') > sysdate - 60

You need to either put the code below the HTML or load if using the document load event:

<input type="text" id="goal-input" name="goal" />
<script type="text/javascript">
$(function(){
    $("#goal-input").focus();
});
</script>

Update:

Switching divs doesn't trigger the document load event since everything already have been loaded. You need to focus it when you switch div:

if (goal) {
      step1.fadeOut('fast', function() {
          step1.hide();
          step2.fadeIn('fast', function() {  
              $("#name").focus();
          });
      });
}

Since I had everything being forwarded to index.php anyway I thought I would try setting the headers in PHP instead of the .htaccess file and it worked! YAY! Here's what I added to index.php for anyone else having this problem.

// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
    // should do a check here to match $_SERVER['HTTP_ORIGIN'] to a
    // whitelist of safe domains
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");         

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

}

credit goes to slashingweapon for his answer on this question

Because I'm using Slim I added this route so that OPTIONS requests get a HTTP 200 response

// return HTTP 200 for HTTP OPTIONS requests
$app->map('/:x+', function($x) {
    http_response_code(200);
})->via('OPTIONS');

If you are using the excellent

VSCode for Mac, 2020

simply tap Apple-Shift-N (as in "new window")

You can take a look at InterpolatedUnivariateSpline

Here an example using it:

import matplotlib.pyplot as plt
import numpy as np
from scipy.interpolate import InterpolatedUnivariateSpline

# given values
xi = np.array([0.2, 0.5, 0.7, 0.9])
yi = np.array([0.3, -0.1, 0.2, 0.1])
# positions to inter/extrapolate
x = np.linspace(0, 1, 50)
# spline order: 1 linear, 2 quadratic, 3 cubic ... 
order = 1
# do inter/extrapolation
s = InterpolatedUnivariateSpline(xi, yi, k=order)
y = s(x)

# example showing the interpolation for linear, quadratic and cubic interpolation
plt.figure()
plt.plot(xi, yi)
for order in range(1, 4):
    s = InterpolatedUnivariateSpline(xi, yi, k=order)
    y = s(x)
    plt.plot(x, y)
plt.show()

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

DECLARE @FDate DATETIME='05-05-2019' /*This is first date*/
 GETDATE()/*This is Current date*/
SELECT (DATEDIFF(DAY,(@LastDate),GETDATE())) As DifferenceDays/*this query will return no of days between firstdate & Current date*/

check this one out.

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">

<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">

<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

it should end up like this in the $_POST[] array (PHP format for easy visualization)

$_POST[] = array(
    'firstname'=>'value',
    'lastname'=>'value',
    'email'=>'value',
    'address'=>'value',
    'tree' => array(
        'tree1'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree2'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree3'=>array(
            'fruit'=>'value',
            'height'=>'value'
        )
    )
)

min-width and max-width properties do not work the way you expect for table cells. From spec:

In CSS 2.1, the effect of 'min-width' and 'max-width' on tables, inline tables, table cells, table columns, and column groups is undefined.

This hasn't changed in CSS3.

If you only need to prevent line-breaks on space characters, you can use   entities between words:

No line break

instead of

<span style="white-space:nowrap">No line break</span>

If you set up a click binding in Knockout the event is passed as the second parameter. You can use the event to obtain the element that the click occurred on and perform whatever action you want.

Here is a fiddle that demonstrates: http://jsfiddle.net/jearles/xSKyR/

Alternatively, you could create your own custom binding, which will receive the element it is bound to as the first parameter. On init you could attach your own click event handler to do any actions you wish.

http://knockoutjs.com/documentation/custom-bindings.html

HTML

<div>
    <button data-bind="click: clickMe">Click Me!</button>
</div>

Js

var ViewModel = function() {
    var self = this;
    self.clickMe = function(data,event) {

      var target = event.target || event.srcElement;

      if (target.nodeType == 3) // defeat Safari bug
        target = target.parentNode;

      target.parentNode.innerHTML = "something";
    }
}

ko.applyBindings(new ViewModel());

First, to describe dynamic cast in C terms, we have to represent classes in C. Classes with virtual functions use a "VTABLE" of pointers to the virtual functions. Comments are C++. Feel free to reformat and fix compile errors...

// class A { public: int data; virtual int GetData(){return data;} };
typedef struct A { void**vtable; int data;} A;
int AGetData(A*this){ return this->data; }
void * Avtable[] = { (void*)AGetData };
A * newA() { A*res = malloc(sizeof(A)); res->vtable = Avtable; return res; }

// class B : public class A { public: int moredata; virtual int GetData(){return data+1;} }
typedef struct B { void**vtable; int data; int moredata; } B;
int BGetData(B*this){ return this->data + 1; }
void * Bvtable[] = { (void*)BGetData };
B * newB() { B*res = malloc(sizeof(B)); res->vtable = Bvtable; return res; }

// int temp = ptr->GetData();
int temp = ((int(*)())ptr->vtable[0])();

Then a dynamic cast is something like:

// A * ptr = new B();
A * ptr = (A*) newB();
// B * aB = dynamic_cast<B>(ptr);
B * aB = ( ptr->vtable == Bvtable ? (B*) aB : (B*) 0 );

It is worth pointing out that on Safari on the iPhone, at least, inserting basic HTML tags such as <b>, <i>, and <img> (which ideally you shouldn't use in other circumstances anymore anyway, preferring CSS) into the body parameter in the mailto: does appear to work - they are honored within the email client. I haven't done exhaustive testing to see if this is supported by other mobile or desktop browser/email client combos. It's also dubious whether this is really standards-compliant. Might be useful if you are building for that platform, though.

As other responses have noted, you should also use encodeURIComponent on the entire body before embedding it in the mailto: link.

GitLens has a nice Git history browser. Install GitLens from the extensions marketplace, and then run "Show GitLens Explorer" from the command palette.

localeCompare() is slow, so if you don't care about the "correct" ordering of non-English-character strings, try your original method or the cleaner-looking:

str1 < str2 ? -1 : +(str1 > str2)

This is an order of magnitude faster than localeCompare() on my machine.

The + ensures that the answer is always numeric rather than boolean.

2 methods,

1. You can check usage about snippet using help()
2. you can check hidden code for those modules using inspect

1) inspect:

use inpsect module to explore code you want... NOTE: you can able to explore code only for modules (aka) packages you have imported

for eg:

  >>> import randint  
  >>> from inspect import getsource
  >>> getsource(randint) # here i am going to explore code for package called `randint`

2) help():

you can simply use help() command to get help about builtin functions as well its code.

for eg: if you want to see the code for str() , simply type - help(str)

it will return like this,

>>> help(str)
Help on class str in module __builtin__:

class str(basestring)
 |  str(object='') -> string
 |
 |  Return a nice string representation of the object.
 |  If the argument is a string, the return value is the same object.
 |
 |  Method resolution order:
 |      str
 |      basestring
 |      object
 |
 |  Methods defined here:
 |
 |  __add__(...)
 |      x.__add__(y) <==> x+y

 |  __eq__(...)
 |      x.__eq__(y) <==> x==y
 |

In C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning.

To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-* flags if possible.

Instead of stdlib.h, you should try:

#include <string.h>

That's where strcpy and strncpy are defined, at least according to the strcpy(2) man page.

The exit function is defined in stdlib.h, though, so I don't know what's going on there.

I suggest the NavUtils.navigateUpFromSameTask(), it's easy and very simple, you can learn it from the google developer.Wish I could help you!

"Dominant Color" is tricky. What you want to do is compare the distance between each pixel and every other pixel in color space (Euclidean Distance), and then find the pixel whose color is closest to every other color. That pixel is the dominant color. The average color will usually be mud.

I wish I had MathML in here to show you Euclidean Distance. Google it.

I have accomplished the above execution in RGB color space using PHP/GD here: https://gist.github.com/cf23f8bddb307ad4abd8

This however is very computationally expensive. It will crash your system on large images, and will definitely crash your browser if you try it in the client. I have been working on refactoring my execution to: - store results in a lookup table for future use in the iteration over each pixel. - to divide large images into grids of 20px 20px for localized dominance. - to use the euclidean distance between x1y1 and x1y2 to figure out the distance between x1y1 and x1y3.

Please let me know if you make progress on this front. I would be happy to see it. I will do the same.

Canvas is definitely the best way to do this in the client. SVG is not, SVG is vector based. After I get the execution down, the next thing I want to do is get this running in the canvas (maybe with a webworker for each pixel's overall distance calculation).

Another thing to think about is that RGB is not a good color space for doing this in, because the euclidean distance between colors in RGB space is not very close to the visual distance. A better color space for doing this might be LUV, but I have not found a good library for this, or any algorythims for converting RGB to LUV.

An entirely different approach would be to sort your colors in a rainbow, and build a histogram with tolerance to account for varying shades of a color. I have not tried this, because sorting colors in a rainbow is hard, and so are color histograms. I might try this next. Again, let me know if you make any progress here.

Honestly, I have difficulty implementing it because there's barely any tutorials I've searched that displays writing the keys into the files. The accepted answer was "fine". But for me I had to improve it so that both keys gets saved into two separate files. I've written a helper class so y'all just gotta copy and paste it. Hope this helps lol.

I just encountered this problem and contrary to the accepted solution of "your make files are broken" and "host includes should never be included in a cross compile"

The android build includes many host executables used by the SDK to build an android app. In my case the make stopped while building zipalign, which is used to optimize an apk before installing on an android device.

Installing lib32z1-dev solved my problem, under Ubuntu you can install it with the following command:

sudo apt-get install lib32z1-dev

You can try something like this:

$scope.test = "test1,test2";
{{test.split(',')[0]}}

now you will get "test1" while you try {{test.split(',')[0]}}

and you will get "test2" while you try {{test.split(',')[1]}}

here is my plnkr:

Use a UIWebView on iOS 5-.

On iOS 6+ you can use UITextView.attributedString, see https://stackoverflow.com/a/20996085 for how.

There's also an undocumented -[UITextView setContentToHTMLString:] method. Do not use this if you want to submit to AppStore.

In the code of the button that saves the changes to the database eg the update button, add the following lines of code:

MyDataGridView.DataSource = MyTableBindingSource

MyDataGridView.Update()

MyDataGridView.RefreshEdit()

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

@SophieAlpert is right, +1, I just want to provide a modified version of her solution, without jQuery, based on this answer.

var WindowDimensions = React.createClass({
    render: function() {
        return <span>{this.state.width} x {this.state.height}</span>;
    },
    updateDimensions: function() {

    var w = window,
        d = document,
        documentElement = d.documentElement,
        body = d.getElementsByTagName('body')[0],
        width = w.innerWidth || documentElement.clientWidth || body.clientWidth,
        height = w.innerHeight|| documentElement.clientHeight|| body.clientHeight;

        this.setState({width: width, height: height});
        // if you are using ES2015 I'm pretty sure you can do this: this.setState({width, height});
    },
    componentWillMount: function() {
        this.updateDimensions();
    },
    componentDidMount: function() {
        window.addEventListener("resize", this.updateDimensions);
    },
    componentWillUnmount: function() {
        window.removeEventListener("resize", this.updateDimensions);
    }
});

As per https://stackoverflow.com/a/33859341/446250, having internet connection sharing enabled for my ethernet adapter ended up causing this problem for me. Disabling the sharing fixed the problem

For your literal example you'd want to use the adjacent selector (+).

h4 + p {color:red}//any <p> that is immediately preceded by an <h4>

<h4>Some text</h4>
<p>I'm red</p>
<p>I'm not</p>

However, if you wanted to select all successive paragraphs, you'd need to use the general sibling selector (~).

h4 ~ p {color:red}//any <p> that has the same parent as, and comes after an <h4>

<h4>Some text</h4>
<p>I'm red</p>
<p>I am too</p>

It's known to be buggy in IE 7+ unfortunately.

generally . doesn't match newlines, so try ((.|\n)*)<foobar>

First of all, %d is for a int

So %1.16lld makes no sense, because %d is an integer

That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.

What you want to use is the type double, for calculating pi and then using %f or %1.16f.

If you want an explicit check against false (and not undefined, null and others which I assume as you are using !== instead of !=) then yes, you have to use that.

Also, this is the same in a slightly smaller footprint:

if(borrar() !== !1)

fileExists() is a method of FileSystemObject, not a global scope function.

You also have an issue with the delete, DeleteFile() is also a method of FileSystemObject.

Furthermore, it seems you are moving the file and then attempting to deal with the overwrite issue, which is out of order. First you must detect the name collision, so you can choose the rename the file or delete the collision first. I am assuming for some reason you want to keep deleting the new files until you get to the last one, which seemed implied in your question.

So you could use the block:

if NOT fso.FileExists(newname) Then  

    file.move fso.buildpath(OUT_PATH, newname)           

else

    fso.DeleteFile newname
    file.move fso.buildpath(OUT_PATH, newname)  

end if 

Also be careful that your string comparison with the = sign is case sensitive. Use strCmp with vbText compare option for case insensitive string comparison.

A complete pywin32 example using loop or subthread

After working on this on and off for a few days, here is the answer I would have wished to find, using pywin32 to keep it nice and self contained.

This is complete working code for one loop-based and one thread-based solution. It may work on both python 2 and 3, although I've only tested the latest version on 2.7 and Win7. The loop should be good for polling code, and the tread should work with more server-like code. It seems to work nicely with the waitress wsgi server that does not have a standard way to shut down gracefully.

I would also like to note that there seems to be loads of examples out there, like this that are almost useful, but in reality misleading, because they have cut and pasted other examples blindly. I could be wrong. but why create an event if you never wait for it?

That said I still feel I'm on somewhat shaky ground here, especially with regards to how clean the exit from the thread version is, but at least I believe there are nothing misleading here.

To run simply copy the code to a file and follow the instructions.

update:

Use a simple flag to terminate thread. The important bit is that "thread done" prints.
For a more elaborate example exiting from an uncooperative server thread see my post about the waitress wsgi server.
