This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

Here's a fix for LoaderException errors you're likely to find if one of the types sublasses a type in another assembly:

// Setup event handler to resolve assemblies
AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(CurrentDomain_ReflectionOnlyAssemblyResolve);

Assembly a = System.Reflection.Assembly.ReflectionOnlyLoadFrom(filename);
a.GetTypes();
// process types here

// method later in the class:
static Assembly CurrentDomain_ReflectionOnlyAssemblyResolve(object sender, ResolveEventArgs args)
{
    return System.Reflection.Assembly.ReflectionOnlyLoad(args.Name);
}

That should help with loading types defined in other assemblies.

Hope that helps!

Let me just add to the answers above, that optimizing images, and serving responsive images helps page loading times dramatically since >90% of web traffic are images. You might want to pre-process images using JS / Node modules such as imagemin and related plug-ins, ideally during the build process with Grunt or Gulp.

Optimizing images means processing finding an ideal image type, and selecting optimal compression to achieve a balance between image quality and file size.

Serving responsive images translates into creating several sizes and formats of each image automatically and using srcset in your HTML allows you to serve optimal image set (that is, the ideal format and dimensions, thus optimal file size) for every single browser).

Image processing automation during the build process means incorporating it up once, and presenting optimized images further on, requiring minimum extra time.

Some great read on responsive images, minification in general, imagemin node module and using srcset.

May this could helpful for some people. I had a naughty error: undefined reference to symbol '_ZN5boost6system15system_categoryEv' //usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0: error adding symbols: DSO missing from command line There were some issue of cmakeList.txt and somehow I was missing to explicitly include the "system" and "filesystem" libraries. So, I wrote these lines in CMakeLists.txt

These lines are written at the beginning before creating the executable of the project, as at this stage we don't need to link boost library to our project executable.

reinterpret_cast cannot be used for this conversion, the code will not compile. According to C++03 standard section 5.2.10-1:

Conversions that can be performed explicitly using reinterpret_cast are listed below. No other conversion can be performed explicitly using reinterpret_cast.

This conversion is not listed in that section. Even this is invalid:

long l = reinterpret_cast<long>(i)

static_cast is the one which has to be used here. See this and this SO questions.

I used the following code to apply some external CSS:

infowindow.open(map, marker);

I use the file *nix command to convert a unknown charset file in a utf-8 file

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

\\. is the simple answer. Here is simple code for your help.

while (line != null) {
    //             
    String[] words = line.split("\\.");
    wr = "";
    mean = "";
    if (words.length > 2) {
        wr = words[0] + words[1];
        mean = words[2];

    } else {
        wr = words[0];
        mean = words[1];
    }
}

It depends on the context. For the content, it is < and &, and ]]> (though a string of three instead of one character).

For attribute values, it is <, &, ", and '.

For CDATA, it is ]]>.

Hey... it worked for me!

• For your cookies, see this answer.
• For PHP's own session cookie (PHPSESSID, by default), see @richie's answer

The setcookie() and setrawcookie() functions, introduced the httponly parameter, back in the dark ages of PHP 5.2.0, making this nice and easy. Simply set the 7th parameter to true, as per the syntax

Function syntax simplified for brevity

setcookie(    $name, $value, $expire, $path, $domain, $secure, $httponly )
setrawcookie( $name, $value, $expire, $path, $domain, $secure, $httponly )

In PHP < 8, specify NULL for parameters you wish to remain as default.

In PHP >= 8 you can benefit from using named parameters. See this question about named params.

setcookie( $name, $value, httponly:true )

It is also possible using the older, lower-level header() function:

header( "Set-Cookie: name=value; httpOnly" );

You may also want to consider if you should be setting the secure parameter.

This sounds like modifying the __builtin__ name space. To do it:

import __builtin__
__builtin__.foo = 'some-value'

Do not use the __builtins__ directly (notice the extra "s") - apparently this can be a dictionary or a module. Thanks to ??O????? for pointing this out, more can be found here.

Now foo is available for use everywhere.

I don't recommend doing this generally, but the use of this is up to the programmer.

Assigning to it must be done as above, just setting foo = 'some-other-value' will only set it in the current namespace.

You can use my package mahotas on Python 3. It is numpy-based rather than PIL based.

The caret character works, however the next line should not start with double quotes. e.g. this will not work:

C:\ ^
"SampleText" ..

Start next line without double quotes (not a valid example, just to illustrate)

UPDATE or DELETE a record isn't allowed in Hive, but INSERT INTO is acceptable.
A snippet from Hadoop: The Definitive Guide(3rd edition):

Updates, transactions, and indexes are mainstays of traditional databases. Yet, until recently, these features have not been considered a part of Hive's feature set. This is because Hive was built to operate over HDFS data using MapReduce, where full-table scans are the norm and a table update is achieved by transforming the data into a new table. For a data warehousing application that runs over large portions of the dataset, this works well.

Hive doesn't support updates (or deletes), but it does support INSERT INTO, so it is possible to add new rows to an existing table.

There are a few options:

• Nest the AsyncTask class within your Activity class. Assuming you don't use the same task in multiple activities, this is the easiest way. All your code stays the same, you just move the existing task class to be a nested class inside your activity's class.

  public class MyActivity extends Activity {
      // existing Activity code
      ...
  
      private class MyAsyncTask extends AsyncTask<String, Void, String> {
          // existing AsyncTask code
          ...
      }
  }
  

• Create a custom constructor for your AsyncTask that takes a reference to your Activity. You would instantiate the task with something like new MyAsyncTask(this).execute(param1, param2).

  public class MyAsyncTask extends AsyncTask<String, Void, String> {
      private Activity activity;
  
      public MyAsyncTask(Activity activity) {
          this.activity = activity;
      }
  
      // existing AsyncTask code
      ...
  }
  

Here is a PHP based parser that parses HTML using some ungodly regex. As the author of this project, I can tell you it is possible to parse HTML with regex, but not efficient. If you need a server-side solution (as I did for my wp-Typography WordPress plugin), this works.

Either Collections.emptyMap(), or if type inference doesn't work in your case,
Collections.<String, String>emptyMap()

For my particular case it was due to the fact that the Origin ALB behind my CloudFront Behavior had a DEFAULT ACM certificate which was pointing to a different domain name.

To fix this I had to:

1. Go to the ALB
2. Under the Listeners tab, selected my Listener and then Edit
3. Under the Default SSL Certificate, choose the correct Origin Certificate.

Ok, try this:

Get the image with the transparent circle - http://i39.tinypic.com/15s97vd.png Put that image in a html element and change that element's background color via css. This way you get the logo with the circle in the color defined in the stylesheet.

The html

<div class="badassColorChangingLogo">
    <img src="http://i39.tinypic.com/15s97vd.png" /> 
    Or download the image and change the path to the downloaded image in your machine
</div>

The css

div.badassColorChangingLogo{
    background-color:white;
}
div.badassColorChangingLogo:hover{
    background-color:blue;
}

Keep in mind that this wont work on non-alpha capable browsers like ie6, and ie7. for ie you can use a js fix. Google ddbelated png fix and you can get the script.

You start by writing a class that derives from Attribute:

public class MyCustomAttribute: Attribute
{
    public string SomeProperty { get; set; }
}

Then you could decorate anything (class, method, property, ...) with this attribute:

[MyCustomAttribute(SomeProperty = "foo bar")]
public class Foo
{

}

and finally you would use reflection to fetch it:

var customAttributes = (MyCustomAttribute[])typeof(Foo).GetCustomAttributes(typeof(MyCustomAttribute), true);
if (customAttributes.Length > 0)
{
    var myAttribute = customAttributes[0];
    string value = myAttribute.SomeProperty;
    // TODO: Do something with the value
}

You could limit the target types to which this custom attribute could be applied using the AttributeUsage attribute:

/// <summary>
/// This attribute can only be applied to classes
/// </summary>
[AttributeUsage(AttributeTargets.Class)]
public class MyCustomAttribute : Attribute

Important things to know about attributes:

• Attributes are metadata.
• They are baked into the assembly at compile-time which has very serious implications of how you could set their properties. Only constant (known at compile time) values are accepted
• The only way to make any sense and usage of custom attributes is to use Reflection. So if you don't use reflection at runtime to fetch them and decorate something with a custom attribute don't expect much to happen.
• The time of creation of the attributes is non-deterministic. They are instantiated by the CLR and you have absolutely no control over it.

Why not use margin? you can apply all kinds off margins to an element. Not just the whole margin around it.

You should use css classes since this is referencing more than one element and you can use id's for those that you want to be different specifically

i.e:

<style>
.box { height: 50px; background: #0F0; width: 100%; margin-top: 10px; }
#first { margin-top: 20px; }
#second { background: #00F; }
h1.box { background: #F00; margin-bottom: 50px;  }
</style>

<h1 class="box">Hello World</h1>
<div class="box" id="first"></div>
<div class="box" id="second"></div>?

You can return multiple value inside a xml data type in "case" expression, then extract them, also "else" block is available

SELECT 
xmlcol.value('(value1)[1]', 'NVARCHAR(MAX)') AS value1,
xmlcol.value('(value2)[1]', 'NVARCHAR(MAX)') AS value2
FROM
(SELECT CASE
WHEN <condition 1> THEN

ELSE
CAST((SELECT a3 AS value1, b3 AS value2 FOR XML PATH('')) AS XML)
END AS xmlcol
FROM <table>) AS tmp

A couple problems, you aren't delaying by much (.sleep is milliseconds, not seconds), and you're attempting to print in your catch statement. Your code should look more like:

if (i==1) {
    try {
        System.out.println("Scanning...");
        Thread.sleep(1000); // 1 second
    } catch (InterruptedException ex) {
        // handle error
    }
}

  static Point Cartesian(double x, double y);

Bootstrap 3 now has Responsive tables out of the box. Hooray! :)

You can check it here: https://getbootstrap.com/docs/3.3/css/#tables-responsive

Add a <div class="table-responsive"> surrounding your table and you should be good to go:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

To make it work on all layouts you can do this:

.table-responsive
{
    overflow-x: auto;
}

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

From this link you can try different diagrams.

In case you need to split a string from your JSON, the string has the \n special character replaced with \\n.

Split string by newline:

Result.split('\n');

Split string received in JSON, where special character \n was replaced with \\n during JSON.stringify(in javascript) or json.json_encode(in PHP). So, if you have your string in a AJAX response, it was processed for transportation. and if it is not decoded, it will sill have the \n replaced with \\n** and you need to use:

Result.split('\\n');

Note that the debugger tools from your browser might not show this aspect as you was expecting, but you can see that splitting by \\n resulted in 2 entries as I need in my case:

There's nothing in the BCL to do this for you, but there are two great libraries for .NET which do support the functionality.

• SharpZipLib
• DotNetZip

I've used both and can say that the two are very complete and have well-designed APIs, so it's mainly a matter of personal preference.

I'm not sure whether they explicitly support adding Folders rather than just individual files to zip files, but it should be quite easy to create something that recursively iterated over a directory and its sub-directories using the DirectoryInfo and FileInfo classes.

$date = '2014-02-25';
date('D', strtotime($date));

In case the file your variable holds doesn't actually exist the FOR approach won't work. One trick you could use, if you know the length of the extension, is taking a substring:

%var:~0,-4%

the -4 means that the last 4 digits (presumably .ext) will be truncated.

The first thing you should do is to determine whether you want to keep the local changes before you delete the commit message.

Use git log to show current commit messages, then find the commit_id before the commit that you want to delete, not the commit you want to delete.

If you want to keep the locally changed files, and just delete commit message:

git reset --soft commit_id

If you want to delete all locally changed files and the commit message:

git reset --hard commit_id

That's the difference of soft and hard

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

I found this to be the easiest way to change it server side.

For me what did the trick was running the command

git config auto.crlf false

inside the folder of the project, I wanted it specifically for one project.

That command changed the file in path {project_name}/.git/config (fyi .git is a hidden folder) by adding the lines

[auto]
    crlf = false

at the end of the file. I suppose changing the file does the same trick as well.

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

In AngularJS you can redirect your form (on submit) to other page by using window.location.href=''; like below:

postData(email){
    if (email=='undefined') {
      this.Utils.showToast('Invalid Email');
    } else {
      var origin = 'Dubai';
      this.download.postEmail(email, origin).then(data => { 
           ...
      });
      window.location.href = "https://www.thesoftdesign.com/";      
    }
  }

Simply try this:

window.location.href = "https://www.thesoftdesign.com/"; 

I fix without .row

<div class="col col-33 left" ng-repeat="photo in photos">
   Content here...
</div>

and css

.left {
  float: left;
}

from zipfile import ZipFile
ZipFile("YOURZIP.zip").extractall("YOUR_DESTINATION_DIRECTORY")

The directory where you will extract your files doesn't need to exist before, you name it at this moment

YOURZIP.zip is the name of the zip if your project is in the same directory. If not, use the PATH i.e : C://....//YOURZIP.zip

Think to escape the / by an other / in the PATH If you have a permission denied try to launch your ide (i.e: Anaconda) as administrator

YOUR_DESTINATION_DIRECTORY will be created in the same directory than your project

the above approach didn't work for me on Android Studio 3.0. It still shows the background. I just made an empty background file

<?xml version="1.0" encoding="utf-8"?>
<vector
android:height="108dp"
android:width="108dp"
android:viewportHeight="108"
android:viewportWidth="108"
xmlns:android="http://schemas.android.com/apk/res/android">
</vector>

This worked except the full bleed layers

First, do not use DataOutputStream unless it’s really necessary. Second:

Socket socket = new Socket("host", port);
OutputStream socketOutputStream = socket.getOutputStream();
socketOutputStream.write(message);

Of course this lacks any error checking but this should get you going. The JDK API Javadoc is your friend and can help you a lot.

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

This error means that for whatever reason the client cannot connect to the port on the computer running server script. This can be caused by few things, like lack of routing to the destination, but since you can ping the server, it should not be the case. The other reason might be that you have a firewall somewhere between your client and the server - it could be on server itself or on the client. Given your network addressing, I assume both server and client are on the same LAN, so there shouldn't be any router/firewall involved that could block the traffic. In this case, I'd try the following:

• check if you really have that port listening on the server (this should tell you if your code does what you think it should): based on your OS, but on linux you could do something like netstat -ntulp
• check from the server, if you're accepting the connections to the server: again based on your OS, but telnet LISTENING_IP LISTENING_PORT should do the job
• check if you can access the port of the server from the client, but not using the code: just us the telnet (or appropriate command for your OS) from the client

and then let us know the findings.

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

Why not perform a clone and then delete the .git directory so that you just have a bare working copy?

Edit: Or in fact why use clone at all? It's a bit confusing when you say that you want a git repo but without a .git directory. If you mean that you just want a copy of some state of the tree then why not do cp -R in the shell instead of the git clone and then delete the .git afterwards.

My job recently tasked me with logging all the tracebacks/exceptions from our application. I tried numerous techniques that others had posted online such as the one above but settled on a different approach. Overriding traceback.print_exception.

I have a write up at http://www.bbarrows.com/ That would be much easier to read but Ill paste it in here as well.

When tasked with logging all the exceptions that our software might encounter in the wild I tried a number of different techniques to log our python exception tracebacks. At first I thought that the python system exception hook, sys.excepthook would be the perfect place to insert the logging code. I was trying something similar to:

import traceback
import StringIO
import logging
import os, sys

def my_excepthook(excType, excValue, traceback, logger=logger):
    logger.error("Logging an uncaught exception",
                 exc_info=(excType, excValue, traceback))

sys.excepthook = my_excepthook  

This worked for the main thread but I soon found that the my sys.excepthook would not exist across any new threads my process started. This is a huge issue because most everything happens in threads in this project.

After googling and reading plenty of documentation the most helpful information I found was from the Python Issue tracker.

The first post on the thread shows a working example of the sys.excepthook NOT persisting across threads (as shown below). Apparently this is expected behavior.

import sys, threading

def log_exception(*args):
    print 'got exception %s' % (args,)
sys.excepthook = log_exception

def foo():
    a = 1 / 0

threading.Thread(target=foo).start()

The messages on this Python Issue thread really result in 2 suggested hacks. Either subclass Thread and wrap the run method in our own try except block in order to catch and log exceptions or monkey patch threading.Thread.run to run in your own try except block and log the exceptions.

The first method of subclassing Thread seems to me to be less elegant in your code as you would have to import and use your custom Thread class EVERYWHERE you wanted to have a logging thread. This ended up being a hassle because I had to search our entire code base and replace all normal Threads with this custom Thread. However, it was clear as to what this Thread was doing and would be easier for someone to diagnose and debug if something went wrong with the custom logging code. A custome logging thread might look like this:

class TracebackLoggingThread(threading.Thread):
    def run(self):
        try:
            super(TracebackLoggingThread, self).run()
        except (KeyboardInterrupt, SystemExit):
            raise
        except Exception, e:
            logger = logging.getLogger('')
            logger.exception("Logging an uncaught exception")

The second method of monkey patching threading.Thread.run is nice because I could just run it once right after __main__ and instrument my logging code in all exceptions. Monkey patching can be annoying to debug though as it changes the expected functionality of something. The suggested patch from the Python Issue tracker was:

def installThreadExcepthook():
    """
    Workaround for sys.excepthook thread bug
    From
http://spyced.blogspot.com/2007/06/workaround-for-sysexcepthook-bug.html

    Call once from __main__ before creating any threads.
    If using psyco, call psyco.cannotcompile(threading.Thread.run)
    since this replaces a new-style class method.
    """
    init_old = threading.Thread.__init__
    def init(self, *args, **kwargs):
        init_old(self, *args, **kwargs)
        run_old = self.run
        def run_with_except_hook(*args, **kw):
            try:
                run_old(*args, **kw)
            except (KeyboardInterrupt, SystemExit):
                raise
            except:
                sys.excepthook(*sys.exc_info())
        self.run = run_with_except_hook
    threading.Thread.__init__ = init

It was not until I started testing my exception logging I realized that I was going about it all wrong.

To test I had placed a

raise Exception("Test")

somewhere in my code. However, wrapping a a method that called this method was a try except block that printed out the traceback and swallowed the exception. This was very frustrating because I saw the traceback bring printed to STDOUT but not being logged. It was I then decided that a much easier method of logging the tracebacks was just to monkey patch the method that all python code uses to print the tracebacks themselves, traceback.print_exception. I ended up with something similar to the following:

def add_custom_print_exception():
    old_print_exception = traceback.print_exception
    def custom_print_exception(etype, value, tb, limit=None, file=None):
        tb_output = StringIO.StringIO()
        traceback.print_tb(tb, limit, tb_output)
        logger = logging.getLogger('customLogger')
        logger.error(tb_output.getvalue())
        tb_output.close()
        old_print_exception(etype, value, tb, limit=None, file=None)
    traceback.print_exception = custom_print_exception

This code writes the traceback to a String Buffer and logs it to logging ERROR. I have a custom logging handler set up the 'customLogger' logger which takes the ERROR level logs and send them home for analysis.

If you're using a self hosted site like me, the way to avoid this problem (as described above) is to stipulate on both the host and client side that the wsHttpBinding security mode = NONE.

When creating the binding, both on the client and the host, you can use this code:

 Dim binding as System.ServiceModel.WSHttpBinding 
 binding= New System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None)

or

 System.ServiceModel.WSHttpBinding binding
 binding = new System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None);

Yes - a bit of a misfeature of the queue class, IMHO. This is what I do:

#include <queue>
using namespace std;;

int main() {
    queue <int> q1;
    // stuff
    q1 = queue<int>();  
}

You can use view.setZ(float) starting from API level 21. Here you can find more info.

I'd like to ask why you are trying to detect when the content of the textbox changed in real time?

An alternative would be to set a timer (via setIntval?) and compare last saved value to the current one and then reset a timer. This would guarantee catching ANY change, whether caused by keys, mouse, some other input device you didn't consider, or even JavaScript changing the value (another possiblity nobody mentioned) from a different part of the app.

I was going through some details related to tuple and list, and what I understood is:

• Tuples are Heterogeneous collection data type
• Tuple has Fixed length (per tuple type)
• Tuple are Always finite

So for appending new item to a tuple, need to cast it to list, and do append() operation on it, then again cast it back to tuple.

But personally what I felt about the Question is, if Tuples are supposed to be finite, fixed length items and if we are using those data types in our application logics then there should not be a scenario to appending new items OR updating an item value in it. So instead of list of tuples it should be list of list itself, Am I right on this?

Utilizing the fact that you can do set operations on arrays by doing &(intersection), -(difference), and |(union).

Obviously I didn't implement the MultiSet to spec, but this should get you started:

class MultiSet
  attr_accessor :set
  def initialize(set)
    @set = set
  end
  # intersection
  def &(other)
    @set & other.set
  end
  # difference
  def -(other)
    @set - other.set
  end
  # union
  def |(other)
    @set | other.set
  end
end

x = MultiSet.new([1,1,2,2,3,4,5,6])
y = MultiSet.new([1,3,5,6])

p x - y # [2,2,4]
p x & y # [1,3,5,6]
p x | y # [1,2,3,4,5,6]

Ternary expressions are very useful in JS, especially React. Here's a simplified answer to the many good, detailed ones provided.

condition ? expressionIfTrue : expressionIfFalse

Think of expressionIfTrue as the OG if statement rendering true;
think of expressionIfFalse as the else statement.

Example:

var x = 1;
(x == 1) ? y=x : y=z;

this checked the value of x, the first y=(value) returned if true, the second return after the colon : returned y=(value) if false.

Just add the following code after the final message you give using PHP code

Print'window.location.assign("index.php")

In Swift:

override func drawRect(dirtyRect: NSRect) {

    NSColor.greenColor().setFill()
    NSRectFill(dirtyRect)

    super.drawRect(dirtyRect)
}

If you need more than one location, you need more than one task. One copy task can copy only from one location (including multiple files) to another one on the node.

- copy: src=/file1 dest=/destination/file1
- copy: src=/file2 dest=/destination/file2

# copy each file over that matches the given pattern
- copy: src={{ item }} dest=/destination/
  with_fileglob:
    - /files/*

System.Text.ASCIIEncoding.Unicode.GetByteCount(yourString);

Or

System.Text.ASCIIEncoding.ASCII.GetByteCount(yourString);

The following can be used to retreive an environment parameter:

println System.getenv("MY_PARAM") 

<div class = "solTitle"> <a href = "#"  id = "solution0" onClick = "openSolution();">Solution0 </a></div> <br>

<div class= "solTitle"> <a href = "#"  id = "solution1" onClick = "openSolution();">Solution1 </a></div> <br>



$(document).ready(function(){
    $('.solTitle a').click(function(e) {
        e.preventDefault();
        alert('here in');
         var divId = 'summary' +$(this).attr('id');

        document.getElementById(divId).className = ''; /* or $('#'+divid).removeAttr('class'); */

    });
 });

I changed few things:

1. remove the onclick attr and bind click event inside the document.ready
2. changed solTitle to be an ID to a CLASS: id cant be repeated

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

While the accepted answer isn't technically wrong, it doesn't answer the original question nor the follow up question in the comments, which was what I came here looking for. But I figured it out, so here goes.

If you want to find all Posts that have Users (and only the ones that have users) where the SQL would look like this:

SELECT * FROM posts INNER JOIN users ON posts.user_id = users.id

Which is semantically the same thing as the OP's original SQL:

SELECT * FROM posts, users WHERE posts.user_id = users.id

then this is what you want:

Posts.findAll({
  include: [{
    model: User,
    required: true
   }]
}).then(posts => {
  /* ... */
});

Setting required to true is the key to producing an inner join. If you want a left outer join (where you get all Posts, regardless of whether there's a user linked) then change required to false, or leave it off since that's the default:

Posts.findAll({
  include: [{
    model: User,
//  required: false
   }]
}).then(posts => {
  /* ... */
});

If you want to find all Posts belonging to users whose birth year is in 1984, you'd want:

Posts.findAll({
  include: [{
    model: User,
    where: {year_birth: 1984}
   }]
}).then(posts => {
  /* ... */
});

Note that required is true by default as soon as you add a where clause in.

If you want all Posts, regardless of whether there's a user attached but if there is a user then only the ones born in 1984, then add the required field back in:

Posts.findAll({
  include: [{
    model: User,
    where: {year_birth: 1984}
    required: false,
   }]
}).then(posts => {
  /* ... */
});

If you want all Posts where the name is "Sunshine" and only if it belongs to a user that was born in 1984, you'd do this:

Posts.findAll({
  where: {name: "Sunshine"},
  include: [{
    model: User,
    where: {year_birth: 1984}
   }]
}).then(posts => {
  /* ... */
});

If you want all Posts where the name is "Sunshine" and only if it belongs to a user that was born in the same year that matches the post_year attribute on the post, you'd do this:

Posts.findAll({
  where: {name: "Sunshine"},
  include: [{
    model: User,
    where: ["year_birth = post_year"]
   }]
}).then(posts => {
  /* ... */
});

I know, it doesn't make sense that somebody would make a post the year they were born, but it's just an example - go with it. :)

I figured this out (mostly) from this doc:

• http://docs.sequelizejs.com/en/latest/docs/models-usage/#eager-loading

You can add a new Primary Key column to an existing table, which can have sequence numbers, using command:

ALTER TABLE mydb.mytable ADD pk_columnName INT IDENTITY 

Native JS solution:

 document.querySelector('input[name=gender][value=Female]').checked = true;

http://jsfiddle.net/jzQvH/75/

HTML:

<input type='radio' name='gender' value='Male'> Male
<input type='radio' name='gender' value='Female'>Female

Make sure you have added all your changes to the staging area before running

git mv oldFolderName newFoldername

git fails with error

fatal: bad source, source=oldFolderName/somepath/somefile.foo, destination=newFolderName/somepath/somefile.foo

if there are any unadded files, so I just found out.

def printProgressBar(value,label):
    n_bar = 40 #size of progress bar
    max = 100
    j= value/max
    sys.stdout.write('\r')
    bar = '¦' * int(n_bar * j)
    bar = bar + '-' * int(n_bar * (1-j))

    sys.stdout.write(f"{label.ljust(10)} | [{bar:{n_bar}s}] {int(100 * j)}% ")
    sys.stdout.flush()

call:

printProgressBar(30,"IP")

IP | [¦¦¦¦¦¦¦¦¦¦¦¦----------------------------] 30%

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

This topic really helped me, so I'd like to share my improvements. All credits go to the nixda, this is based on his answer.

For those who need to convert multiple csv's in a folder, just modify the directory. Outputfilenames will be identical to input, just with another extension.

Take care of the cleanup in the end, if you like to keep the original csv's you might not want to remove these.

Can be easily modifed to save the xlsx in another directory.

$workingdir = "C:\data\*.csv"
$csv = dir -path $workingdir
foreach($inputCSV in $csv){
$outputXLSX = $inputCSV.DirectoryName + "\" + $inputCSV.Basename + ".xlsx"
### Create a new Excel Workbook with one empty sheet
$excel = New-Object -ComObject excel.application 
$excel.DisplayAlerts = $False

### Build the QueryTables.Add command
### QueryTables does the same as when clicking "Data » From Text" in Excel

I found that this answer was causing some crashes on Android versions 9 and 10. I think it's a good approach but when I was looking at some Android code I found out it was missing a constructor. The answer is quite old so at the time there probably was no need for it. When I added the missing constructor and called it from the creator the crash was fixed.

So here is the edited code:

public class CustomView extends LinearLayout {

    private int stateToSave;

    ...

    @Override
    public Parcelable onSaveInstanceState() {
        Parcelable superState = super.onSaveInstanceState();
        SavedState ss = new SavedState(superState);

        // your custom state
        ss.stateToSave = this.stateToSave;

        return ss;
    }

    @Override
    protected void dispatchSaveInstanceState(SparseArray<Parcelable> container)
    {
        dispatchFreezeSelfOnly(container);
    }

    @Override
    public void onRestoreInstanceState(Parcelable state) {
        SavedState ss = (SavedState) state;
        super.onRestoreInstanceState(ss.getSuperState());

        // your custom state
        this.stateToSave = ss.stateToSave;
    }

    @Override
    protected void dispatchRestoreInstanceState(SparseArray<Parcelable> container)
    {
        dispatchThawSelfOnly(container);
    }

    static class SavedState extends BaseSavedState {
        int stateToSave;

        SavedState(Parcelable superState) {
            super(superState);
        }

        private SavedState(Parcel in) {
            super(in);
            this.stateToSave = in.readInt();
        }

        // This was the missing constructor
        @RequiresApi(Build.VERSION_CODES.N)
        SavedState(Parcel in, ClassLoader loader)
        {
            super(in, loader);
            this.stateToSave = in.readInt();
        }

        @Override
        public void writeToParcel(Parcel out, int flags) {
            super.writeToParcel(out, flags);
            out.writeInt(this.stateToSave);
        }    
        
        public static final Creator<SavedState> CREATOR =
            new ClassLoaderCreator<SavedState>() {
          
            // This was also missing
            @Override
            public SavedState createFromParcel(Parcel in, ClassLoader loader)
            {
                return Build.VERSION.SDK_INT >= Build.VERSION_CODES.N ? new SavedState(in, loader) : new SavedState(in);
            }

            @Override
            public SavedState createFromParcel(Parcel in) {
                return new SavedState(in, null);
            }

            @Override
            public SavedState[] newArray(int size) {
                return new SavedState[size];
            }
        };
    }
}

In my case it was a button, and apparently, with buttons, this is only a problem in Firefox. Solution found here:

button::-moz-focus-inner {
  border: 0;
}

This works with express for me:

app.get("*",(req,res,next) => {
    if (req.headers["x-forwarded-proto"]) {
        res.redirect("https://" + req.headers.host + req.url)
    }
    if (!res.headersSent) {
        next()
    }
})

Put this before all HTTP handlers.

Gustavo Niemeyer's answer is great. But in Windows, runtime proc is mostly in another dir, like this:

"C:\Users\XXX\AppData\Local\Temp"

If you use relative file path, like "/config/api.yaml", this will use your project path where your code exists.

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

Your should also separate the javascript from the HTML.
HTML:

<a href="#" id="function-click"><img title="next page" alt="next page" src="/themes/me/img/arrn.png"></a>

javascript:

myLink = document.getElementById('function-click');
myLink.onclick = ShowOld(2367,146986,2);

Just make sure the last line in the ShowOld function is:

return false;

as this will stop the link from opening in the browser.

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

This might be overkill - but be careful doing anything which relies on the extension of PHP files being .php - what if someone comes along later and adds handlers for .php4 or even .html so they're handled by PHP. You might be better off serving files out of those directories from a different instance of Apache or something, which only serves static content.

Your problem is the dependency of spring batch spring-boot-starter-batch that has a spring-boot-starter-jdbc transitive maven dependency.

Spring Batch is a framework for building reliable and fault tolerance enterprise batch jobs. It supports many features like restarting a failed batch, recording the status of the batch execution and so on. In order to achieve that Spring Batch uses a database schema to store the status of the registered jobs, the auto-configuration already provides you the basic configuration of the required data source and it is this configuration that requires the relational database configuration.

To solve this you must include some database driver like mysql, h2, etc. to configure the url.

Update: Just for getting start you can configure your application.yml like below:

spring:
  datasource:
    driver-class-name: org.h2.Driver
    url: jdbc:h2:mem:localhost;DB_CLOSE_ON_EXIT=FALSE
    username: admin
    password:

and of course in your pom.xml include the h2 dirver like this:

The motivation, because you can not use mongo for this purpose, is that the usage of mongo is provided only for item readers and writers and not for managing the internal database of Spring Batch that is an internal schema, not a business schema. The query is plain SQL query and the internal abstraction relies on a relational database. It is necessary to have a database with ACID capability because every batch reads and writes a chunk of work and saves that information in order to restart the job. A NoSql solution is not suitable for this.

At the end you have configured a relational database in order to prepare Spring Batch for internal capability, the internal abstraction does not rely on mongo only on jdbc. Then mongo can be used but for the business side of the batch via item reader/writer.

I hope that this can help you to clear your doubts.

I implemented maxlength behaviour on textarea recently, and run into problem described in this question: Chrome counts characters wrong in textarea with maxlength attribute.

So all implementations listed here will work little buggy. To solve this issue I add .replace(/(\r\n|\n|\r)/g, "11") before .length. And kept it in mind when cuting string.

I ended with something like this:

var maxlength = el.attr("maxlength");
var val = el.val();
var length = val.length;
var realLength = val.replace(/(\r\n|\n|\r)/g, "11").length;
if (realLength > maxlength) {
    el.val(val.slice(0, maxlength - (realLength - length)));
}

Don't sure if it solves problem completely, but it works for me for now.

public static <T> void copyAvalableFields(@NotNull T source, @NotNull T target) throws IllegalAccessException {
    Field[] fields = source.getClass().getDeclaredFields();
    for (Field field : fields) {
        if (!Modifier.isStatic(field.getModifiers())
                && !Modifier.isFinal(field.getModifiers())) {
            field.set(target, field.get(source));
        }
    }
}

We read all the fields of the class. Filter non-static and non-final fields from the result. But there may be an error accessing non-public fields. For example, if this function is in the same class, and the class being copied does not contain public fields, an access error will occur. The solution may be to place this function in the same package or change access to public or in this code inside the loop call field.setAccessible (true); what will make the fields available

The Newest MySQL Versions have the new BIT data type in which you can specify the number of bits in the field, for example BIT(1) to use as Boolean type, because it can be only 0 or 1.

There are a plethora of ways in which this can be done. The problem is how to make R aware of the locations of the variables you wish to divide.

Assuming

d <- read.table(text = "263807.0    1582
196190.5    1016
586689.0    3479
")
names(d) <- c("min", "count2.freq")
> d
       min count2.freq
1 263807.0        1582
2 196190.5        1016
3 586689.0        3479

My preferred way

To add the desired division as a third variable I would use transform()

> d <- transform(d, new = min / count2.freq)
> d
       min count2.freq      new
1 263807.0        1582 166.7554
2 196190.5        1016 193.1009
3 586689.0        3479 168.6373

The basic R way

If doing this in a function (i.e. you are programming) then best to avoid the sugar shown above and index. In that case any of these would do what you want

## 1. via `[` and character indexes
d[, "new"] <- d[, "min"] / d[, "count2.freq"]

## 2. via `[` with numeric indices
d[, 3] <- d[, 1] / d[, 2]

## 3. via `$`
d$new <- d$min / d$count2.freq

All of these can be used at the prompt too, but which is easier to read:

d <- transform(d, new = min / count2.freq)

or

d$new <- d$min / d$count2.freq ## or any of the above examples

Hopefully you think like I do and the first version is better ;-)

The reason we don't use the syntactic sugar of tranform() et al when programming is because of how they do their evaluation (look for the named variables). At the top level (at the prompt, working interactively) transform() et al work just fine. But buried in function calls or within a call to one of the apply() family of functions they can and often do break.

Likewise, be careful using numeric indices (## 2. above); if you change the ordering of your data, you will select the wrong variables.

The preferred way if you don't need replacement

If you are just wanting to do the division (rather than insert the result back into the data frame, then use with(), which allows us to isolate the simple expression you wish to evaluate

> with(d, min / count2.freq)
[1] 166.7554 193.1009 168.6373

This is again much cleaner code than the equivalent

> d$min / d$count2.freq
[1] 166.7554 193.1009 168.6373

as it explicitly states that "using d, execute the code min / count2.freq. Your preference may be different to mine, so I have shown all options.

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

If you have an element that does not have a specific selector and you still want to check if it is a descendant of another element, you can use jQuery.contains()

jQuery.contains( container, contained )
Description: Check to see if a DOM element is a descendant of another DOM element.

You can pass the parent element and the element that you want to check to that function and it returns if the latter is a descendant of the first.

Use the Count(*) analytic function OVER PARTITION BY NULL This will count the total # of rows

In your Manifest file, for each Activity that you want to lock the screen rotation add: if you want to lock it in horizontal mode:

<activity
        ...
        ...
        android:screenOrientation="landscape">

or if you want to lock it in vertical mode:

<activity
            ...
            ...
            android:screenOrientation="portrait">

>>> "{:.1f}".format(45.34531)
'45.3'

Or use the builtin round:

>>> round(45.34531, 1)
45.299999999999997

If you are using Node/Chrome. The following snippet will get you extension which meets the following requirements.

• err instanceof Error
• err instanceof CustomErrorType
• console.log() returns [CustomErrorType] when created with a message
• console.log() returns [CustomErrorType: message] when created without a message
• throw/stack provides the information at the point the error was created.
• Works optimally in Node.JS, and Chrome.
• Will pass instanceof checks in Chrome, Safari, Firefox and IE 8+, but will not have a valid stack outside of Chrome/Safari. I'm OK with that because I can debug in chrome, but code which requires specific error types will still function cross browser. If you need Node only you can easily remove the if statements and you're good to go.

Snippet

var CustomErrorType = function(message) {
    if (Object.defineProperty) {
        Object.defineProperty(this, "message", {
            value : message || "",
            enumerable : false
        });
    } else {
        this.message = message;
    }

    if (Error.captureStackTrace) {
        Error.captureStackTrace(this, CustomErrorType);
    }
}

CustomErrorType.prototype = new Error();
CustomErrorType.prototype.name = "CustomErrorType";

Usage

var err = new CustomErrorType("foo");

Output

var err = new CustomErrorType("foo");
console.log(err);
console.log(err.stack);

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

I wrote my own library to achieve the intended behaviour in ios Maps app. It is a protocol oriented solution. So you don't need to inherit any base class instead create a sheet controller and configure as you wish. It also supports inner navigation/presentation with or without UINavigationController.

See below link for more details.

It worked for me:

CGFloat boldTextFontSize = 17.0f;

myLabel.text = [NSString stringWithFormat:@"%@ 2012/10/14 %@",@"Updated:",@"21:59 PM"];

NSRange range1 = [myLabel.text rangeOfString:@"Updated:"];
NSRange range2 = [myLabel.text rangeOfString:@"21:59 PM"];

NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:myLabel.text];

[attributedText setAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:boldTextFontSize]}
                        range:range1];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:boldTextFontSize]}
                        range:range2];

myLabel.attributedText = attributedText;

A Structure which contain a reference to itself. A common occurrence of this in a structure which describes a node for a link list. Each node needs a reference to the next node in the chain.

struct node
{
       int data;
       struct node *next; // <-self reference
};

You should put it in the <head>. I typically put style references above JS and I order my JS from top to bottom if some of them are dependent on others, but I beleive all of the references are loaded before the page is rendered.

This is a corner image

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

        android:drawable="@drawable/img_main_blue"
        android:bottom="5dp"
        android:left="5dp"
        android:right="5dp"

        <shape

</layer-list>

If it's an NSMutableString (which I would recommend since you're changing it dynamically), you can use:

[myString deleteCharactersInRange:NSMakeRange([myRequestString length]-1, 1)];

The most correct way is to use HttpContext.Current.Server.MapPath("~/App_Data");. This means you can only retrieve the path from a method where the HttpContext is available. It makes sense: the App_Data directory is a web project folder structure [1].

If you need the path to ~/App_Data from a class where you don't have access to the HttpContext you can always inject a provider interface using your IoC container:

public interface IAppDataPathProvider
{
    string GetAppDataPath();
}

Implement it using your HttpApplication:

public class AppDataPathProvider : IAppDataPathProvider
{
    public string GetAppDataPath()
    {
        return MyHttpApplication.GetAppDataPath();
    }
}

Where MyHttpApplication.GetAppDataPath looks like:

public class MyHttpApplication : HttpApplication
{
    // of course you can fetch&store the value at Application_Start
    public static string GetAppDataPath()
    {
        return HttpContext.Current.Server.MapPath("~/App_Data");
    }
}

I had the same problem, made all the workarounds you advised: still the same error. I updated Eclipse via "Help / Check for updates" and now everything is ok. This update brought a completely new version of the Android SDK Manager.

This works for me:

File file  = new File("c:\\myjar.jar");

URL url = file.toURL();  
URL[] urls = new URL[]{url};

ClassLoader cl = new URLClassLoader(urls);
Class cls = cl.loadClass("com.mypackage.myclass");

I dont think youre returning json object from server. just a string.

you need the dataType of the return object to be json

Colspan:

<table>
   <tr>
      <td> Row 1 Col 1</td>
      <td> Row 1 Col 2</td>
</tr>
<tr>
      <td colspan=2> Row 2 Long Col</td>
</tr>
</table>

You can use array_column for that.

$search_value = '5465';
$search_key   = 'uid';
$user = array_search($search_value, array_column($userdb, $search_key));

print_r($userdb[$user]);

5465 is the user ID you want to search, uid is the key that contains user ID and $userdb is the array that is defined in the question.

If you have something like this:

var json = [ {a:b, c:d}, {e:f, g:h, ...}, {..}, ... ]

then, you can do:

alert(json.length)

Returning a list from apply is a dangerous operation as the resulting object is not guaranteed to be either a Series or a DataFrame. And exceptions might be raised in certain cases. Let's walk through a simple example:

df = pd.DataFrame(data=np.random.randint(0, 5, (5,3)),
                  columns=['a', 'b', 'c'])
df
   a  b  c
0  4  0  0
1  2  0  1
2  2  2  2
3  1  2  2
4  3  0  0

There are three possible outcomes with returning a list from apply

1) If the length of the returned list is not equal to the number of columns, then a Series of lists is returned.

df.apply(lambda x: list(range(2)), axis=1)  # returns a Series
0    [0, 1]
1    [0, 1]
2    [0, 1]
3    [0, 1]
4    [0, 1]
dtype: object

2) When the length of the returned list is equal to the number of columns then a DataFrame is returned and each column gets the corresponding value in the list.

df.apply(lambda x: list(range(3)), axis=1) # returns a DataFrame
   a  b  c
0  0  1  2
1  0  1  2
2  0  1  2
3  0  1  2
4  0  1  2

3) If the length of the returned list equals the number of columns for the first row but has at least one row where the list has a different number of elements than number of columns a ValueError is raised.

i = 0
def f(x):
    global i
    if i == 0:
        i += 1
        return list(range(3))
    return list(range(4))

df.apply(f, axis=1) 
ValueError: Shape of passed values is (5, 4), indices imply (5, 3)

Answering the problem without apply

Using apply with axis=1 is very slow. It is possible to get much better performance (especially on larger datasets) with basic iterative methods.

Create larger dataframe

df1 = df.sample(100000, replace=True).reset_index(drop=True)

Timings

# apply is slow with axis=1
%timeit df1.apply(lambda x: mylist[x['col_1']: x['col_2']+1], axis=1)
2.59 s ± 76.8 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

# zip - similar to @Thomas
%timeit [mylist[v1:v2+1] for v1, v2 in zip(df1.col_1, df1.col_2)]  
29.5 ms ± 534 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

@Thomas answer

%timeit list(map(get_sublist, df1['col_1'],df1['col_2']))

I spent a lot of time to use SerialPort class and has concluded to use SerialPort.BaseStream class instead. You can see source code: SerialPort-source and SerialPort.BaseStream-source for deep understanding. I created and use code that shown below.

• The core function public int Recv(byte[] buffer, int maxLen) has name and works like "well known" socket's recv().

• It means that

  • in one hand it has timeout for no any data and throws TimeoutException.
  • In other hand, when any data has received,
    • it receives data either until maxLen bytes
    • or short timeout (theoretical 6 ms) in UART data flow

.

public class Uart : SerialPort

    {
        private int _receiveTimeout;

        public int ReceiveTimeout { get => _receiveTimeout; set => _receiveTimeout = value; }

        static private string ComPortName = "";

        /// <summary>
        /// It builds PortName using ComPortNum parameter and opens SerialPort.
        /// </summary>
        /// <param name="ComPortNum"></param>
        public Uart(int ComPortNum) : base()
        {
            base.BaudRate = 115200; // default value           
            _receiveTimeout = 2000;
            ComPortName = "COM" + ComPortNum;

            try
            {
                base.PortName = ComPortName;
                base.Open();
            }
            catch (UnauthorizedAccessException ex)
            {
                Console.WriteLine("Error: Port {0} is in use", ComPortName);
            }
            catch (Exception ex)
            {
                Console.WriteLine("Uart exception: " + ex);

@Travis solution is right, but it loses milliseconds when a Date is generated. I have added a line to include the milliseconds into the date:

If you don't need this precision, use the Travis solution because it will be faster.

extension Date {

    func toMillis() -> Int64! {
        return Int64(self.timeIntervalSince1970 * 1000)
    }

    init(millis: Int64) {
        self = Date(timeIntervalSince1970: TimeInterval(millis / 1000))
        self.addTimeInterval(TimeInterval(Double(millis % 1000) / 1000 ))
    }

}

Chrome 56 is not accepting this kind of patterns (Chrome 56 is accpeting 11.11. an additional .) with type number, use type as text as progress.

I use div instead of tables and am able to target classes within the main class, as below:

CSS

.main {
    .width: 800px;
    .margin: 0 auto;
    .text-align: center;
}
.main .table {
    width: 80%;
}
.main .row {
   / ***something ***/
}
.main .column {
    font-size: 14px;
    display: inline-block;
}
.main .left {
    width: 140px;
    margin-right: 5px;
    font-size: 12px;
}
.main .right {
    width: auto;
    margin-right: 20px;
    color: #fff;
    font-size: 13px;
    font-weight: normal;
}

HTML

<div class="main">
    <div class="table">
        <div class="row">
            <div class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

If you want to style a particular "cell" exclusively you can use another sub-class or the id of the div e.g:

.main #red { color: red; }

<div class="main">
    <div class="table">
        <div class="row">
            <div id="red" class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

I was using the following:

from module import Foo

foo_instance = Foo()

but to get rid of circular reference I did the following and it worked:

import module.foo

foo_instance = foo.Foo()

XML Schema requires that the xml namespace be declared and imported before using xml:lang (and other xml namespace values) RELAX NG predeclares the xml namespace, as in XML, so no additional declaration is needed.

You would use the Console class

char[] password = console.readPassword("Enter password");  
Arrays.fill(password, ' ');

By executing readPassword echoing is disabled. Also after the password is validated it is best to overwrite any values in the array.

If you run this from an ide it will fail, please see this explanation for a thorough answer: Explained

I think the point of those different types of logging is if you want your app to basically self filter its own logs. So Verbose could be to log absolutely everything of importance in your app, then the debug level would log a subset of the verbose logs, and then Info level will log a subset of the debug logs. When you get down to the Error logs, then you just want to log any sort of errors that may have occured. There is also a debug level called Fatal for when something really hits the fan in your app.

In general, you're right, it's basically arbitrary, and it's up to you to define what is considered a debug log versus informational, versus and error, etc. etc.

Try the 'requests' module, it's much simpler.

#pip install requests for installation

import requests

url = 'https://www.google.com/'
r = requests.get(url)
r.text

more info here > http://docs.python-requests.org/en/master/

Another option is to rely on good old fashion equals method. As long as the argument in the when mock equals the argument in the code being tested, then Mockito will match the mock.

Here is an example.

public class MyPojo {

    public MyPojo( String someField ) {
        this.someField = someField;
    }

    private String someField;

    @Override
    public boolean equals( Object o ) {
        if ( this == o ) return true;
        if ( o == null || getClass() != o.getClass() ) return false;
        MyPojo myPojo = ( MyPojo ) o;
        return someField.equals( myPojo.someField );
    }

}

then, assuming you know what the value for someField will be, you can mock it like this.

when(fooDao.getBar(new MyPojo(expectedSomeField))).thenReturn(myFoo);

pros: This is more explicit then any matchers. As a reviewer of code, I keep an eye open for any in the code junior developers write, as it glances over their code's logic to generate the appropriate object being passed.

con: Sometimes the field being passed to the object is a random ID. For this case you cannot easily construct the expected argument object in your mock code.

Another possible approach is to use Mockito's Answer object that can be used with the when method. Answer lets you intercept the actual call and inspect the input argument and return a mock object. In the example below I am using any to catch any request to the method being mocked. But then in the Answer lambda, I can further inspect the Bazo argument... maybe to verify that a proper ID was passed to it. I prefer this over any by itself so that at least some inspection is done on the argument.

    Bar mockBar = //generate mock Bar.

    when(fooDao.getBar(any(Bazo.class))
    .thenAnswer(  ( InvocationOnMock invocationOnMock) -> {
        Bazo actualBazo = invocationOnMock.getArgument( 0 );

        //inspect the actualBazo here and thrw exception if it does not meet your testing requirements.
        return mockBar;
    } );

So to sum it all up, I like relying on equals (where the expected argument and actual argument should be equal to each other) and if equals is not possible (due to not being able to predict the actual argument's state), I'll resort to Answer to inspect the argument.

According to Microsoft: To serve the Swagger UI at the app's root (http://localhost:/), set the RoutePrefix property to an empty string:

app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
c.RoutePrefix = string.Empty;
});

Want to format it automatically when you save the file???

then Goto Window > Preferences > Java > Editor > Save Actions

and configure your save actions.

Along with saving, you can format, Organize imports,add modifier ‘final’ where possible etc

No longer

now append is a method in JavaScript

MDN documentation on append method

Quoting MDN

The ParentNode.append method inserts a set of Node objects or DOMString objects after the last child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.

This is not supported by IE and Edge but supported by Chrome(54+), Firefox(49+) and Opera(39+).

The JavaScript's append is similar to jQuery's append.

You can pass multiple arguments.

var elm = document.getElementById('div1');
elm.append(document.createElement('p'),document.createElement('span'),document.createElement('div'));
console.log(elm.innerHTML);

<div id="div1"></div>

Works fine, except if you have spaces or escaped characters. I don't find the way to capture arguments in this case and send to a ssh inside of script.

This could be useful but is so ugly

_command_opts=$( echo "$@" | awk -F\- 'BEGIN { OFS=" -" } { for (i=2;i<=NF;i++) { gsub(/^[a-z] /,"&@",$i) ; gsub(/ $/,"",$i );gsub (/$/,"@",$i) }; print $0 }' | tr '@' \' )

The HttpRequest class represents the request made to the server and has various properties associated with it, such as QueryString.

The ASP.NET run-time parses a request to the server and populates this information for you.

Read HttpRequest Properties for a list of all the potential properties that get populated on you behalf by ASP.NET.

Note: not all properties will be populated, for instance if your request has no query string, then the QueryString will be null/empty. So you should check to see if what you expect to be in the query string is actually there before using it like this:

if (!String.IsNullOrEmpty(Request.QueryString["pID"]))
{
    // Query string value is there so now use it
    int thePID = Convert.ToInt32(Request.QueryString["pID"]);
}

Or you can do the following shortcut :

MAC : Shift + Command + A (Enter Action menu pops up)

And write : Optimize Imports

Explain only shows how the optimizer thinks the query will execute.

To show the real plan, you will need to run the sql once. Then use the same session run the following:

@yoursql 
select * from table(dbms_xplan.display_cursor()) 

This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".

1. Upto my knowledge, Heap space is occupied by instance variables only. If this is correct, then why this error occurred after running fine for sometime as space for instance variables are alloted at the time of object creation.

That means you are creating more objects in your application over a period of time continuously. New objects will be stored in heap memory and that's the reason for growth in heap memory.

Heap not only contains instance variables. It will store all non-primitive data types ( Objects). These objects life time may be short (method block) or long (till the object is referenced in your application)

2. Is there any way to increase the heap space?

Yes. Have a look at this oracle article for more details.

There are two parameters for setting the heap size:

-Xms:, which sets the initial and minimum heap size

-Xmx:, which sets the maximum heap size

3. What changes should I made to my program so that It will grab less heap space?

It depends on your application.

1. Set the maximum heap memory as per your application requirement

2. Don't cause memory leaks in your application

3. If you find memory leaks in your application, find the root cause with help of profiling tools like MAT, Visual VM , jconsole etc. Once you find the root cause, fix the leaks.

Important notes from oracle article

Cause: The detail message Java heap space indicates object could not be allocated in the Java heap. This error does not necessarily imply a memory leak.

Possible reasons:

1. Improper configuration ( not allocating sufficiant memory)
2. Application is unintentionally holding references to objects and this prevents the objects from being garbage collected
3. Applications that make excessive use of finalizers. If a class has a finalize method, then objects of that type do not have their space reclaimed at garbage collection time. If the finalizer thread cannot keep up, with the finalization queue, then the Java heap could fill up and this type of OutOfMemoryError exception would be thrown.

On a different note, use better Garbage collection algorithms ( CMS or G1GC)

Have a look at this question for understanding G1GC

Note that the NSString stringWithContentsOfURL will report a totally different user-agent string than the UIWebView making the same request. So if your server is user-agent aware, and sending back different html depending on who is asking for it, you may not get correct results this way.

Also note that the @"document.body.innerHTML" mentioned above will only display what is in the body tag. If you use @"document.all[0].innerHTML" you will get both head and body. Which is still not the complete contents of the UIWebView, since it will not get back the !doctype or html tags, but it is a lot closer.

You have to read database columnhere. You could have a look on following code snippet

                string connectionString = ConfigurationManager.ConnectionStrings["NameOfYourSqlConnectionString"].ConnectionString;
                using (var _connection = new SqlConnection(connectionString))
                {
                    _connection.Open();

                    using (SqlCommand command = new SqlCommand("SELECT SomeColumnName FROM TableName", _connection))
                    {

                        SqlDataReader sqlDataReader = command.ExecuteReader();
                        if (sqlDataReader.HasRows)
                        {
                            while (sqlDataReader.Read())
                            {
                                string YourFirstDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString(); // Remember Type Casting is required here it has to be according to database column data type
                                string YourSecondDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString();
                                string YourThridDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString();

                            }
                        }
                        sqlDataReader.Close();
                    }
                    _connection.Close();

Having read above that svg is inline by default, I just added the following to the div:

<div style="text-align:center;">

and it did the trick for me.

Purists may not like it (it’s an image, not text) but in my opinion HTML and CSS screwed up over centring, so I think it’s justified.

string constr = @"Data Source=(LocalDB)\v11.0;Initial Catalog=Bank;Integrated Security=True;Pooling=False";
SqlConnection con = new SqlConnection(constr);
DataSet ds = new DataSet();
con.Open();
SqlCommand cmd = new SqlCommand(" UPDATE Account  SET name = Aleesha, CID = 24 Where name =Areeba and CID =11 )";
cmd.ExecuteNonQuery();

I found this page when I was trying to set the backgroundImage attribute of a div, but hadn't wrapped the backgroundImage value with url(). This worked fine:

for (var i=0; i<20; i++) {
  // add a wrapper around an image element
  var wrapper = document.createElement('div');
  wrapper.className = 'image-cell';

  // add the image element
  var img = document.createElement('div');
  img.className = 'image';
  img.style.backgroundImage = 'url(http://via.placeholder.com/350x150)';

  // add the image to its container; add both to the body
  wrapper.appendChild(img);
  document.body.appendChild(wrapper);
}

If one or both of your dates are in the future, then I'm afraid you're SOL if you want to-the-second accuracy. UTC time has leap seconds that aren't known until about 6 months before they happen, so any dates further out than that can be inaccurate by some number of seconds (and in practice, since people don't update their machines that often, you may find that any time in the future is off by some number of seconds).

This gives a good explanation of the theory of designing date/time libraries and why this is so: http://www.boost.org/doc/libs/1_41_0/doc/html/date_time/details.html#date_time.tradeoffs

The same as @Nix with a small change to be strongly typed:

If you don't want to query for it just create an entity, and then delete it.

                Customer customer = new Customer () { Id = id };
                context.Customers.Attach(customer);
                context.Customers.DeleteObject(customer);
                context.SaveChanges();

This works for me in Visual Studio 2015.

I copy all DLL files from a folder located in a library folder on the same level as my solution folder into the targetdirectory of the project being built.

Using a relative path from my project directory and going up the folder structure two steps with..\..\lib

MySolutionFolder
....MyProject
Lib

if $(ConfigurationName) == Debug (
xcopy /Y "$(ProjectDir)..\..\lib\*.dll" "$(TargetDir)"
) ELSE (echo "Not Debug mode, no file copy from lib")

I am reading some data from a file using read. Here I am reading data in a 2d char pointer but the method is the same for the 1d also. Just read character by character and do not worry about the exceptions because the condition in the while loop is handling the exceptions :D

  while ( (n = read(fd, buffer,1)) > 0 )
{   

if(buffer[0] == '\n')
{
  r++;
  char**tempData=(char**)malloc(sizeof(char*)*r);

  for(int a=0;a<r;a++)
  {
    tempData[a]=(char*)malloc(sizeof(char)*BUF_SIZE);
    memset(tempData[a],0,BUF_SIZE);
  }

  for(int a=0;a<r-1;a++)
  {
    strcpy(tempData[a],data[a]);
  }

   data=tempData;

   c=0;
}

else
{
  data[r-1][c]=buffer[0];
  c++;
  buffer[1]='\0';
}

   }

Here are some things that can fix this (in increasing order of difficulty):

• Clean the project (Product > Clean)

• Manually paste in

  @IBOutlet weak var viewName: UIView!
  // or
  @IBAction func viewTapped(_ sender: Any) { }
  

  and control drag to it. (Change type as needed.) Also see this.

• Completely close Xcode and restart your project.

• Delete the Derived Data folder (Go to Xcode > Preferences > Locations and click the gray arrow by the Derived Data folder. Then delete your project folder.)
• Click delete on the class, remove reference (not Move to Trash), and add it back again. (see this answer)

Go to Control Panel>>System and Security>>System>>Advance system settings>>Environment Variables then set variable value of ANDROID_HOME set it like this "C:\Users\username\AppData\Local\Android\sdk" set username as your pc name, then restart your android studio. after that you can create your AVD again than the error will gone than it will start the virtual device.

it means pointer you can use this link to get more info about pointer http://www.cprogramming.com/tutorial/c/lesson6.html

In jQuery:

var html_string = $('html').outerHTML()

In plain Javascript:

var html_string = document.documentElement.outerHTML

If you want to use @Html.DropDownList , follow.

Controller:

var categoryList = context.Categories.Select(c => c.CategoryName).ToList();

ViewBag.CategoryList = categoryList;

View:

@Html.DropDownList("Category", new SelectList(ViewBag.CategoryList), "Choose Category", new { @class = "form-control" })

$("#Category").on("change", function () {
 var q = $("#Category").val();

console.log("val = " + q);
});

The best way is to set up Apache and to set the access through it. Check the svn book for help. If you don't want to use Apache, you can also do minimalistic access control using svnserve.

Like this:

var str = 'Hello, World, etc';
var myarray = str.split(',');

for(var i = 0; i < myarray.length; i++)
{
   console.log(myarray[i]);
}

There is %history magic for printing and saving the input history (and optionally the output).

To store your current session to a file named my_history.py:

>>> %hist -f my_history.py

History IPython stores both the commands you enter, and the results it produces. You can easily go through previous commands with the up- and down-arrow keys, or access your history in more sophisticated ways.

You can use the %history magic function to examine past input and output. Input history from previous sessions is saved in a database, and IPython can be configured to save output history.

Several other magic functions can use your input history, including %edit, %rerun, %recall, %macro, %save and %pastebin. You can use a standard format to refer to lines:

%pastebin 3 18-20 ~1/1-5

This will take line 3 and lines 18 to 20 from the current session, and lines 1-5 from the previous session.

See %history? for the Docstring and more examples.

Also, be sure to explore the capabilities of %store magic for lightweight persistence of variables in IPython.

Stores variables, aliases and macros in IPython’s database.

d = {'a': 1, 'b': 2}
%store d  # stores the variable
del d

%store -r d  # Refresh the variable from IPython's database.
>>> d
{'a': 1, 'b': 2}

To autorestore stored variables on startup, specifyc.StoreMagic.autorestore = True in ipython_config.py.

$("a").each(function() {
    if (this.href.indexOf('?') != -1) {
        alert("Contains questionmark");
    }
});

Swift

Easier way to get any elements of date as an optional String.

extension Date {

  // Year 
  var currentYear: String? {
    return getDateComponent(dateFormat: "yy")
    //return getDateComponent(dateFormat: "yyyy")
  }

  // Month 
  var currentMonth: String? {
    return getDateComponent(dateFormat: "M")
    //return getDateComponent(dateFormat: "MM")
    //return getDateComponent(dateFormat: "MMM")
    //return getDateComponent(dateFormat: "MMMM")
  }


  // Day
  var currentDay: String? {
    return getDateComponent(dateFormat: "dd")
    //return getDateComponent(dateFormat: "d")
  }


  func getDateComponent(dateFormat: String) -> String? {
    let format = DateFormatter()
    format.dateFormat = dateFormat
    return format.string(from: self)
  }


}

let today = Date()
print("Current Year - \(today.currentYear)")  // result Current Year - Optional("2017")
print("Current Month - \(today.currentMonth)")  // result Current Month - Optional("7")
print("Current Day - \(today.currentDay)")  // result Current Day - Optional("10")

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

This will be the simplest solution. I tried most of the solutions in the internet but only this helped me.

@print{
    @page :footer {color: #fff }

For me it worked perfectly fine.

The WPF Toolkit is available. It is free from CodePlex.

It can be downloaded here. There is some commentary here.

@jing: "The DirectoryInfo solution is much faster then this (especially for network path)"

I cant confirm this. It seems as if Directory.GetFiles triggers a filesystem or network cache. The first request takes a while, but the following requests are much faster, even if new files were added. In my test I did a Directory.getfiles and a info.GetFiles with the same patterns and both run equally

Atom has a built-in line ending selector package

More details here: https://github.com/atom/line-ending-selector

Edit: Whoops, didn't check your question tags before answering.

Check that you can actually connect to DB (have the driver placed? tested the conn when creating it?).

If so, try runnung those queries with F5

Click on Wamp icon and open Apache/httpd.conf and search "#LoadModule rewrite_module modules/mod_rewrite.so". Remove # as below and save it

LoadModule rewrite_module modules/mod_rewrite.so

and restart all service.

You should be using @RequestParam instead of @ModelAttribute, e.g.

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 @RequestParam String someAttr) {
}

You can even omit @RequestParam altogether if you choose, and Spring will assume that's what it is:

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 String someAttr) {
}

As far as I'm aware in order to format a date value you have to handle it in parameterMap,

$('#listDiv').kendoGrid({
            dataSource: {
                type: 'json',
                serverPaging: true,
                pageSize: 10,
                transport: {
                    read: {
                        url: '@Url.Action("_ListMy", "Placement")',
                        data: refreshGridParams,
                        type: 'POST'
                    },
                    parameterMap: function (options, operation) {
                        if (operation != "read") {
                            var d = new Date(options.StartDate);
                            options.StartDate = kendo.toString(new Date(d), "dd/MM/yyyy");
                            return options;
                        }
                        else { return options; }

                    }
                },
                schema: {
                    model: {
                        id: 'Id',
                        fields: {
                            Id: { type: 'number' },
                            StartDate: { type: 'date', format: 'dd/MM/yyyy' },
                            Area: { type: 'string' },
                            Length: { type: 'string' },
                            Display: { type: 'string' },
                            Status: { type: 'string' },
                            Edit: { type: 'string' }
                        }
                    },
                    data: "Data",
                    total: "Count"
                }
            },
            scrollable: false,
            columns:
                [
                    {
                        field: 'StartDate',
                        title: 'Start Date',
                        format: '{0:dd/MM/yyyy}',
                        width: 100
                    },

If you follow the above example and just renames objects like 'StartDate' then it should work (ignore 'data: refreshGridParams,')

For further details check out below link or just search for kendo grid parameterMap ans see what others have done.

This answer was originally edited into the question by the asker.

The problem was that the batch file WAS throwing a silent error. The final POPD was doing no work and was incorrectly called with no opening PUSHD.

Broken code:

CD /D "C:\Program Files (x86)\Olim, LLC\Collybus DR Upload" CALL CollybusUpload.exe POPD

Correct code:

PUSHD "C:\Program Files (x86)\Olim, LLC\Collybus DR Upload" CALL CollybusUpload.exe POPD

Maven

The Answer by Bhesh Gurung is correct… unless your NetBeans project is Maven based.

Dependency

Under Maven, you add a "dependency". A dependency is a description of a library (its name & version number) you want to use from your code.

Or a dependency could be a description of a library which another library needs ("depends on"). Maven automatically handles this chain, libraries that need other libraries that then need other libraries and so on. For the mathematical-minded, perhaps the phrase "Maven resolves the transitive dependencies" makes sense.

Repository

Maven gets this related-ness information, and the libraries themselves from a Maven repository. A repository is basically an online database and collection of download files (the dependency library).

Easy to Use

Adding a dependency to a Maven-based project is really quite easy. That is the whole point to Maven, to make managing dependent libraries easy and to make building them into your project easy. To get started with adding a dependency, see this Question, Adding dependencies in Maven Netbeans and my Answer with screenshot.

Just fixed this issue. import c2 or import numpy was not working. Uninstalled the most current version of numpy. Tried to install numpy==1.15.2 just like specified above, did not work. Tried numpy==1.19.3 IT worked. I guess not all versions work perfectly with all versions of python and dependencies. So keep uninstalling and install one that works.

It would be a lot more simple just to do this;

name = input("What's your name? ")
age = int(input("How old are you? "))
print ("Hi,{0} you will be 21 in {1} years.".format(name, 21 - age))`

Another way

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")

Also, if you keep a list of values in, say A1 to A3, then you can use

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")

The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.

Process Explorer is an excellent tool for troubleshooting. You can try it for finding the problem of high CPU usage. It gives you an insight into the way your application works.

You can also try Procdump to dump the process and analyze what really happened on the CPU.

Add this permission in Manifest,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

File folder = new File(Environment.getExternalStorageDirectory() + 
                             File.separator + "TollCulator");
boolean success = true;
if (!folder.exists()) {
    success = folder.mkdirs();
}
if (success) {
    // Do something on success
} else {
    // Do something else on failure 
}

when u run the application go too DDMS->File Explorer->mnt folder->sdcard folder->toll-creation folder

Aloha from 2018. Unfortunately, I don't have anything cool or futuristic to share with you.

I did however want to point out to those who have commented that the jQuery load() method isn't working in the present are probably trying to use the method with local files without running a local web server. Doing so will throw the above mentioned "cross origin" error, which specifies that cross origin requests such as that made by the load method are only supported for protocol schemes like http, data, or https. (I'm assuming that you're not making an actual cross-origin request, i.e the header.html file is actually on the same domain as the page you're requesting it from)

So, if the accepted answer above isn't working for you, please make sure you're running a web server. The quickest and simplest way to do that if you're in a rush (and using a Mac, which has Python pre-installed) would be to spin up a simple Python http server. You can see how easy it is to do that here.

I hope this helps!

This has worked for me:

System.out.println((char)27 + "[31mThis text would show up red" + (char)27 + "[0m");

You need the ending "[37m" to return the color to white (or whatever you were using). If you don't it may make everything that follows "red".

I searched for hours, and I tried almost everything suggested.
This worked for almost every entity :

$input = "ažškunrukiš ? àéò ??? ©€ ?? ? ?? ? R?";


echo htmlentities($input, ENT_HTML5  , 'UTF-8');

result :

āžšķūņrūķīš ○ àéò ∀∂∋ ©€ ♣♦ ↠ ↔↛ ↙ ℜ℞rx;

Try this:

function someFunction(username, password) {
      return new Promise((resolve, reject) => {
        // Do something with the params username and password...
        if ( /* everything turned out fine */ ) {
          resolve("Stuff worked!");
        } else {
          reject(Error("It didn't work!"));
        }
      });
    }
    
    someFunction(username, password)
      .then((result) => {
        // Do something...
      })
      .catch((err) => {
        // Handle the error...
      });

I found this:

http://www.robvanderwoude.com/commandlineswitches.php#Acrobat

Open a PDF file with navigation pane active, zoom out to 50%, and search for and highlight the word "batch":

AcroRd32.exe /A "zoom=50&navpanes=1=OpenActions&search=batch" PdfFile

First put this somewhere:

private <T> Iterable<T> iteratorToIterable(final Iterator<T> iterator) {
    return new Iterable<T>() {
        @Override
        public Iterator<T> iterator() {
            return iterator;
        }
    };
}

Or if you have access to Java8, just this:

private <T> Iterable<T> iteratorToIterable(Iterator<T> iterator) {
    return () -> iterator;
}

Then simply iterate over the object's keys and values:

for (String key : iteratorToIterable(object.keys())) {
    JSONObject entry = object.getJSONObject(key);
    // ...

static means that the variable or method marked as such is available at the class level. In other words, you don't need to create an instance of the class to access it.

public class Foo {
    public static void doStuff(){
        // does stuff
    }
}

So, instead of creating an instance of Foo and then calling doStuff like this:

Foo f = new Foo();
f.doStuff();

You just call the method directly against the class, like so:

Foo.doStuff();

Solution using pointers:

#include<stdio.h>
#include<stdlib.h>
#define n 3
struct body
{
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double *mass;
};


int main()
{
    struct body *bodies = (struct body*)malloc(n*sizeof(struct body));
    int a, b;
     for(a = 0; a < n; a++)
     {
            for(b = 0; b < 3; b++)
            {
                bodies[a].p[b] = 0;
                bodies[a].v[b] = 0;
                bodies[a].a[b] = 0;
            }
            bodies[a].mass = 0;
            bodies[a].radius = 1.0;
     }

    return 0;
}

I use this subtle alias:

alias vim='gnome-terminal -- vim'

-x is deprecated now. We need to use -- instead

I know this is a very old topic, but the correct answer is still not here.

The accepted answer works with a space, but the user can remove this space - so this answer is not reliable. The answer of Georg works, but is needlessly complex.

To test if the user pressed cancel, just use the following code:

Dim Answer As String = InputBox("Question")
If String.ReferenceEquals(Answer, String.Empty) Then
    'User pressed cancel
Else if Answer = "" Then
    'User pressed ok with an empty string in the box
Else
    'User gave an answer

I'd use RestSharp - https://github.com/restsharp/RestSharp

Create class to deserialize to:

public class MyObject {
    public string Id { get; set; }
    public string Text { get; set; }
    ...
}

And the code to get that object:

RestClient client = new RestClient("http://whatever.com");
RestRequest request = new RestRequest("path/to/object");
request.AddParameter("id", "123");

// The above code will make a request URL of 
// "http://whatever.com/path/to/object?id=123"
// You can pick and choose what you need

var response = client.Execute<MyObject>(request);

MyObject obj = response.Data;

• onSaveInstanceState() is a method used to store data before pausing the activity.
  

Description : Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

• onRestoreInstanceState() is method used to retrieve that data back.
  

Description : This method is called after onStart() when the activity is being re-initialized from a previously saved state, given here in savedInstanceState. Most implementations will simply use onCreate(Bundle) to restore their state, but it is sometimes convenient to do it here after all of the initialization has been done or to allow subclasses to decide whether to use your default implementation. The default implementation of this method performs a restore of any view state that had previously been frozen by onSaveInstanceState(Bundle).

Consider this example here:
You app has 3 edit boxes where user was putting in some info , but he gets a call so if you didn't use the above methods what all he entered will be lost.
So always save the current data in onPause() method of Activity as a bundle & in onResume() method call the onRestoreInstanceState() method .

Please see :

How to use onSavedInstanceState example please

go to your jdk path where you installed your java

For e.g In my PC JDK installed in the following path

"C:\Program Files\Java\jdk1.7.0_17\";

After go to the lib folder e.g "C:\Program Files\Java\jdk1.7.0_17\lib"

in the lib directory there is tool.jar file

Copy this file and past it in the lib forlder of jre7 directory for e.g

"C:\Program Files\Java\jre7\lib"

You declare the variable as extern in a common header:

//globals.h
extern int x;

And define it in an implementation file.

//globals.cpp
int x = 1337;

You can then include the header everywhere you need access to it.

I suggest you also wrap the variable inside a namespace.

This will explain better.

EntityManager em = new JPAUtil().getEntityManager();
Session session = em.unwrap(Session.class);
Criteria c = session.createCriteria(Name.class);

I had the same problem on Windows 7 64-bit Pro. I adjusted network adapters binding using Control panel but nothing changed. Also metrics where showing that Win should use Ethernet adapter as primary, but it didn't.

Then a tried to uninstall Ethernet adapter driver and then install it again (without restart) and then I checked metrics for sure.

After this, Windows started prioritize Ethernet adapter.

Create a seperate xml file in res/drawable folder

 <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="1dp" />
    <solid android:color="@android:color/black" />
</shape>

Connect that xml file (your_file) at the main activity, like this:

DividerItemDecoration divider = new DividerItemDecoration(
    recyclerView.getContext(),
    DividerItemDecoration.VERTICAL
);
divider.setDrawable(ContextCompat.getDrawable(getBaseContext(), R.drawable.your_file));
recyclerView.addItemDecoration(divider);

The problem is that super needs an object as an ancestor:

>>> class oldstyle:
...     def __init__(self): self.os = True

>>> class myclass(oldstyle):
...     def __init__(self): super(myclass, self).__init__()

>>> myclass()
TypeError: must be type, not classobj

On closer examination one finds:

>>> type(myclass)
classobj

But:

>>> class newstyle(object): pass

>>> type(newstyle)
type    

So the solution to your problem would be to inherit from object as well as from HTMLParser. But make sure object comes last in the classes MRO:

>>> class myclass(oldstyle, object):
...     def __init__(self): super(myclass, self).__init__()

>>> myclass().os
True

Your code makes no sense, maybe because it's out of context.

If you mean code like this:

$('a').click(function () {
    callFunction();
    return false;
});

The return false will return false to the click-event. That tells the browser to stop following events, like follow a link. It has nothing to do with the previous function call. Javascript runs from top to bottom more or less, so a line cannot affect a previous line.

I found this question and discussion very helpful and wanted to show the solution I ended up with. It is based on the answer given by @DevangRathod, but I used jQuery and made a couple tweaks to it, so wanted to show a fully commented sample to help anyone else working on something similar. I originally had been using the HTML5 data-list element, but was dissatisfied with that solution since it removes options from the drop down list that don't match text typed in the box. In my application, I wanted the full list to always be available.

Fully functional demo here: https://jsfiddle.net/abru77mm/

HTML:

<!-- 
Most style elements I left to the CSS file, but some are here.
Reason being that I am actually calculating my width dynamically
in my application so when I dynamically formulate this HTML, I
want the width and all the factors (such as padding and border
width and margin) that go into determining the proper widths to
be controlled by one piece of code, so those pieces are done in
the in-line style.  Otherwise I leave the styling to the CSS file.
-->
<div class="data-list-input" style="width:190px;">
  <select class="data-list-input" style="width:190px;">
    <option value="">&lt;Free Form Text&gt;</option>
    <option value="Male">Male</option>
    <option value="Female">Female</option>
    <!-- Note that though the select/option allows for a different
    display and internal value, there is no such distinction in the
    text box, so for all the options (except the "none" option) the
    value and content of the option should be identical. -->
  </select>
  <input class="data-list-input" style="width:160px;padding:4px 6px;border-width:1px;margin:0;" type="text" name="sex" required="required" value="">
</div>

JS:

jQuery(function() {
  //keep the focus on the input box so that the highlighting
  //I'm using doesn't give away the hidden select box to the user
  $('select.data-list-input').focus(function() {
    $(this).siblings('input.data-list-input').focus();
  });
  //when selecting from the select box, put the value in the input box
  $('select.data-list-input').change(function() {
    $(this).siblings('input.data-list-input').val($(this).val());
  });
  //When editing the input box, reset the select box setting to "free
  //form input". This is important to do so that you can reselect the
  //option you had selected if you want to.
  $('input.data-list-input').change(function() {
    $(this).siblings('select.data-list-input').val('');
  });
});

CSS:

div.data-list-input
{
    position: relative;
    height: 20px;
    display: inline-flex;
    padding: 5px 0 5px 0;
}
select.data-list-input
{
    position: absolute;
    top: 5px;
    left: 0px;
    height: 20px;
}
input.data-list-input
{
    position: absolute;
    top: 0px;
    left: 0px;
    height: 20px;
}

Any comments for improvement on my implementation welcome. Hope someone finds this helpful.

I too faced that issue, I was making a silly mistake by repeating the app.use(bodyParser.json()) like below:

app.use(bodyParser.json())
app.use(bodyParser.json({ limit: '50mb' }))

by removing app.use(bodyParser.json()), solved the problem.

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

If you don't need full debugging support, you can now view JavaScript console logs directly within Chrome for iOS at chrome://inspect.

I already answered similar question on here Here is the Link

No both are different.

@Service annotation have use for other purpose and @Controller use for other. Actually Spring @Component, @Service, @Repository and @Controller annotations are used for automatic bean detection using classpath scan in Spring framework, but it doesn't ,mean that all functionalities are same. @Service: It indicates annotated class is a Service component in the business layer.

@Controller: Annotated class indicates that it is a controller components, and mainly used at presentation layer.

The ASPX code will look something like this:

 <asp:RadioButtonList ID="rblist1" runat="server">

    <asp:ListItem Text ="Item1" Value="1" />
    <asp:ListItem Text ="Item2" Value="2" />
    <asp:ListItem Text ="Item3" Value="3" />
    <asp:ListItem Text ="Item4" Value="4" />

    </asp:RadioButtonList>

    <asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />

And the code behind:

protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedValue = rblist1.SelectedValue;
            Response.Write(selectedValue);
        }

I experienced the same errors on a fresh install of VestaCP. I solved the issues by following the instructions on this video.

1. Go to phpmyadmin-fixer and run the appropriate command.
2. Restart Apache, NGINX and MySQL servers.
3. That's it!

const url = 'data:image/png;base6....';
fetch(url)
  .then(res => res.blob())
  .then(blob => {
    const file = new File([blob], "File name",{ type: "image/png" })
  })

Base64 String -> Blob -> File.

Window.Show will show the window, and continue execution -- it's a non-blocking call.

Window.ShowDialog will block the calling thread (kinda ^[1]), and show the dialog. It will also block interaction with the parent/owning window. When the dialog is dismissed (for whatever reason), ShowDialog will return to the caller, and will allow you to access DialogResult (if you want it).

^[1] It will keep the dispatcher pumping by pushing a dispatcher frame onto the WPF dispatcher. This will cause the message pump to keep pumping.

Reload an iframe with jQuery

make a link inside the iframe lets say with id = "reload" then use following code

$('#reload').click(function() {
    document.location.reload();
});

and you are good to go with all browsers.

Reload an iframe with HTML (no Java Script req.)

It have more simpler solution: which works without javaScript in (FF, Webkit)

just make an anchor inSide your iframe

   <a href="#" target="_SELF">Refresh Comments</a>

When you click this anchor it just refresh your iframe

But if you have parameter send to your iframe then do it as following.

  <a id="comnt-limit" href="?id=<?= $page_id?>" target="_SELF">Refresh Comments</a>

do not need any page url because -> target="_SELF" do it for you

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Simple PHP mail script

Using a script like that, you'd POST the contents of your web form to the script, using a function like this:

jQuery.post

And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.
