Simple using html like this downloads the file mentioned using static keyword

<a href="{% static 'bt.docx' %}" class="btn btn-secondary px-4 py-2 btn-sm">Download CV</a>

You can load the project without setting the value of attribute UseIIS to true. Simply follow the below steps:

In the mywebproject.csproj file--

Delete the tag < IISUrl>http://localhost/MyWebApp/< /IISUrl> and save the file. The application will automatically assign the default port to it.

If you get this error in PowerShell, it's most likely because you're using Resolve-Path to resolve a remote path, e.g.

 Resolve-Path \\server\share\path

In this case, Resolve-Path returns an object that, when converted to a string, doesn't return a valid path. It returns PowerShell's internal path:

> [string](Resolve-Path \\server\share\path)
Microsoft.PowerShell.Core\FileSystem::\\server\share\path

The solution is to use the ProviderPath property on the object returned by Resolve-Path:

> Resolve-Path \\server\share\path | Select-Object -ExpandProperty PRoviderPath
\\server\share\path
> (Resolve-Path \\server\share\path).ProviderPath
\\server\share\path

The issue I was facing was I have a project that is dependent on a library project. In order to build I was following these steps:

msbuild.exe myproject.vbproj /T:Rebuild
msbuild.exe myproject.vbproj /T:Package

That of course meant I was missing my library's dll files in bin and most importantly in the package zip file. I found this works perfectly:

msbuild.exe myproject.vbproj /T:Rebuild;Package

I have no idea why this work or why it didn't in the first place. But hope that helps.

I had problems with this following:

https://google-developer-training.github.io/android-developer-fundamentals-course-concepts-v2/appendix/appendix-utilities/appendix-utilities.html

on Android Studio version: 3.3.2

until I killed the .idea/workspace.xml file.

$ cp -rv Testcopysource/ TestCopyDest
$ rm TestCopyDest/.idea/workspace.xml
$ stdio.sh & # Run Android Studio on Linux

Prior to doing that Android Studio would still point to the original source folder and all renames were applied to the original source files (within Testcopysource in my example above).

You need to change

  <activity
        android:name=".YOUR ACTIVITY"
        android:theme="@style/AppTheme.NoActionBar" />
</application>`

these lines in the manifest.It will perfectly work for me.

Step to run in different simulator without any code repo :-

First create a .app by building your project(under project folder in Xcode) and paste it in a appropriate location (See pic for more clarity)

1. Download Xcode
2. Create a demo project and Start simulator in which you want to run the app.
3. Copy the .app file in particular location(ex :- Desktop).
4. cd Desktop and Run the command (xcrun simctl install booted appName.app),
5. App will be installed in the particular booted simulator.

You can make this bit more cleaner by using:

$http.get(url)
    .then(function (response) {
        console.log('get',response)
    })
    .catch(function (data) {
        // Handle error here
    });

Similar to @this.lau_ answer, different approach.

In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).

Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.

This worked for me:

export class Hero{
   id: number;
   name: string;

   public Hero(i: number, n: string){
     this.id = 0;
     this.name = '';
   }
 }

and make sure you initialize as well selectedHero

selectedHero: Hero = new Hero();

While numpy arrays and pandas may be preferrable, this function imitates the behavior of zip(*args) when called as unzip(args).

Allows for generators, like the result from zip in Python 3, to be passed as args as it iterates through values.

def unzip(items, cls=list, ocls=tuple):
    """Zip function in reverse.

    :param items: Zipped-like iterable.
    :type  items: iterable

    :param cls: Container factory. Callable that returns iterable containers,
        with a callable append attribute, to store the unzipped items. Defaults
        to ``list``.
    :type  cls: callable, optional

    :param ocls: Outer container factory. Callable that returns iterable
        containers. with a callable append attribute, to store the inner
        containers (see ``cls``). Defaults to ``tuple``.
    :type  ocls: callable, optional

    :returns: Unzipped items in instances returned from ``cls``, in an instance
        returned from ``ocls``.
    """
    # iter() will return the same iterator passed to it whenever possible.
    items = iter(items)

    try:
        i = next(items)
    except StopIteration:
        return ocls()

    unzipped = ocls(cls([v]) for v in i)

    for i in items:
        for c, v in zip(unzipped, i):
            c.append(v)

    return unzipped

To use list cointainers, simply run unzip(zipped), as

unzip(zip(["a","b","c"],[1,2,3])) == (["a","b","c"],[1,2,3])

To use deques, or other any container sporting append, pass a factory function.

from collections import deque

unzip([("a",1),("b",2)], deque, list) == [deque(["a","b"]),deque([1,2])]

(Decorate cls and/or main_cls to micro manage container initialization, as briefly shown in the final assert statement above.)

Grokking lookaround rapidly.
How to distinguish lookahead and lookbehind? Take 2 minutes tour with me:

(?=) - positive lookahead
(?<=) - positive lookbehind

Suppose

    A  B  C #in a line

Now, we ask B, Where are you?
B has two solutions to declare it location:

One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.

As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.

Your quotes around the 0 make it a string, which is evaluated as true.

Remove the quotes and it should work.

if (0) console.log("ha") 

Your additional threads must be initiated from the same app that is called by the WSGI server.

The example below creates a background thread that executes every 5 seconds and manipulates data structures that are also available to Flask routed functions.

import threading
import atexit
from flask import Flask

POOL_TIME = 5 #Seconds

# variables that are accessible from anywhere
commonDataStruct = {}
# lock to control access to variable
dataLock = threading.Lock()
# thread handler
yourThread = threading.Thread()

def create_app():
    app = Flask(__name__)

    def interrupt():
        global yourThread
        yourThread.cancel()

    def doStuff():
        global commonDataStruct
        global yourThread
        with dataLock:
        # Do your stuff with commonDataStruct Here

        # Set the next thread to happen
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()   

    def doStuffStart():
        # Do initialisation stuff here
        global yourThread
        # Create your thread
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()

    # Initiate
    doStuffStart()
    # When you kill Flask (SIGTERM), clear the trigger for the next thread
    atexit.register(interrupt)
    return app

app = create_app()          

Call it from Gunicorn with something like this:

gunicorn -b 0.0.0.0:5000 --log-config log.conf --pid=app.pid myfile:app

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

As per Apple's documentation:

(void)beginAppearanceTransition:(BOOL)isAppearing animated:(BOOL)animated;

Description:
Tells a child controller its appearance is about to change. If you are implementing a custom container controller, use this method to tell the child that its views are about to appear or disappear. Do not invoke viewWillAppear:, viewWillDisappear:, viewDidAppear:, or viewDidDisappear: directly.

(void)endAppearanceTransition;

Description:

Tells a child controller its appearance has changed. If you are implementing a custom container controller, use this method to tell the child that the view transition is complete.

Sample code:

(void)applicationDidEnterBackground:(UIApplication *)application
{

    [self.window.rootViewController beginAppearanceTransition: NO animated: NO];  // I commented this line

    [self.window.rootViewController endAppearanceTransition]; // I commented this line

}

Question: How I fixed?

Ans: I found this piece of lines in application. This lines made my app not recieving any ViewWillAppear notification's. When I commented these lines it's working fine.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

For me this was the issue. This whole block was missing from the section.

Unnamed namespaces are a utility to make an identifier translation unit local. They behave as if you would choose a unique name per translation unit for a namespace:

namespace unique { /* empty */ }
using namespace unique;
namespace unique { /* namespace body. stuff in here */ }

The extra step using the empty body is important, so you can already refer within the namespace body to identifiers like ::name that are defined in that namespace, since the using directive already took place.

This means you can have free functions called (for example) help that can exist in multiple translation units, and they won't clash at link time. The effect is almost identical to using the static keyword used in C which you can put in in the declaration of identifiers. Unnamed namespaces are a superior alternative, being able to even make a type translation unit local.

namespace { int a1; }
static int a2;

Both a's are translation unit local and won't clash at link time. But the difference is that the a1 in the anonymous namespace gets a unique name.

Read the excellent article at comeau-computing Why is an unnamed namespace used instead of static? (Archive.org mirror).

Make sure the real source file is saved as UTF-8 (You may even want to try the non-recommended BOM Chars with UTF-8 to make sure).

Also in case of HTML, make sure you have declared the correct encoding using meta tags:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

If it's a CMS (as you've tagged your question with Joomla) you may need to configure appropriate settings for the encoding.

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

This diagram will be faster to read next time. Maybe someone else will find that helpful too. This is clearly explained the difference between.

If you're looking to use the standard construct of element = element1 || element2 where JavaScript will return the first one that is truthy, you could do exactly that:

element = $('#someParentElement .somethingToBeFound') || $('#someParentElement .somethingElseToBeFound');

which would return the first element that is actually found. But a better way would probably be to use the jQuery selector comma construct (which returns an array of found elements) in this fashion:

element = $('#someParentElement').find('.somethingToBeFound, .somethingElseToBeFound')[0];

which will return the first found element.

I use that from time to time to find either an active element in a list or some default element if there is no active element. For example:

element = $('ul#someList').find('li.active, li:first')[0] 

which will return any li with a class of active or, should there be none, will just return the last li.

Either will work. There are potential performance penalties, though, as the || will stop processing as soon as it finds something truthy whereas the array approach will try to find all elements even if it has found one already. Then again, using the || construct could potentially have performance issues if it has to go through several selectors before finding the one it will return, because it has to call the main jQuery object for each one (I really don't know if this is a performance hit or not, it just seems logical that it could be). In general, though, I use the array approach when the selector is a rather long string.

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

$( "img.photo" ).load(function() {

    $(".parrentDiv").css('height',$("img.photo").height());
    // very simple

}); 

How do I change Android Studio editor's background color?

Changing Editor's Background

Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there

IDE will display a dialog like this, Press 'No'

Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?

Changing IDE's Theme

Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there

Press OK. Android Studio will ask you to restart the IDE.

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

I also get an EXC_BAD_ACCESS problem.The value in objc_getAssociatedObject() and objc_setAssociatedObject() should be an Object. And the objc_AssociationPolicy should match the Object.

For the record, I think this is more of what he was looking for…

    UIBarButtonItem *l_backButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRewind target:self action:@selector(backToRootView:)];

    self.navigationItem.leftBarButtonItem = l_backButton;


    - (void) backToRootView:(id)sender {

        // Perform some custom code

        [self.navigationController popToRootViewControllerAnimated:YES];
    }

If you're using Tensorflow 2 try the following:

config = tf.compat.v1.ConfigProto()
config.gpu_options.allow_growth = True
session = tf.compat.v1.Session(config=config)

I'd define that I want a maximum number of non-] characters between [ and ]. These need to be escaped with backslashes (and in Java, these need to be escaped again), and the definition of non-] is a character class, thus inside [ and ] (i.e. [^\\]]). The result:

FOO\\[([^\\]]+)\\]

For those of you who faced this issue while creating a controller through the context menu, reopening Visual Studio as an administrator fixed it.

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

VI is always available and will run on the most crippled, single user mode, broken graphics, no keymap, slow link machine - so it's worth knowing how to edit simple files in it just for sysadmin tasks.

Emacs is a complete user interface in an editor. The idea is that you fire up Emacs when you start the machine and never leave it. It's possible to have thousands of sessions present.

Whether learning the capabilities of Emacs are worth it compared to using a GUI editor/IDE and using something like python/awk/etc for extra tasks is up to you.

THis could be another way to browse through the directory structures and provide depth results.

find . -type d  | awk '{print "echo -n \""$0"  \";ls -l "$0" | grep -v total | wc -l" }' | sh 

restarting the adb server as root worked for me. see:

I have found the answer by @Slauma here very useful for speeding things up. I used the same sort of pattern for both inserts and updates - and performance rocketed.

TLDR; Pandas groupby.agg has a new, easier syntax for specifying (1) aggregations on multiple columns, and (2) multiple aggregations on a column. So, to do this for pandas >= 0.25, use

df.groupby('dummy').agg(Mean=('returns', 'mean'), Sum=('returns', 'sum'))

           Mean       Sum
dummy                    
1      0.036901  0.369012

OR

df.groupby('dummy')['returns'].agg(Mean='mean', Sum='sum')

           Mean       Sum
dummy                    
1      0.036901  0.369012

Pandas >= 0.25: Named Aggregation

Pandas has changed the behavior of GroupBy.agg in favour of a more intuitive syntax for specifying named aggregations. See the 0.25 docs section on Enhancements as well as relevant GitHub issues GH18366 and GH26512.

From the documentation,

To support column-specific aggregation with control over the output column names, pandas accepts the special syntax in GroupBy.agg(), known as “named aggregation”, where

• The keywords are the output column names
• The values are tuples whose first element is the column to select and the second element is the aggregation to apply to that column. Pandas provides the pandas.NamedAgg namedtuple with the fields ['column', 'aggfunc'] to make it clearer what the arguments are. As usual, the aggregation can be a callable or a string alias.

You can now pass a tuple via keyword arguments. The tuples follow the format of (<colName>, <aggFunc>).

import pandas as pd

pd.__version__                                                                                                                            
# '0.25.0.dev0+840.g989f912ee'

# Setup
df = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                   'height': [9.1, 6.0, 9.5, 34.0],
                   'weight': [7.9, 7.5, 9.9, 198.0]
})

df.groupby('kind').agg(
    max_height=('height', 'max'), min_weight=('weight', 'min'),)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

Alternatively, you can use pd.NamedAgg (essentially a namedtuple) which makes things more explicit.

df.groupby('kind').agg(
    max_height=pd.NamedAgg(column='height', aggfunc='max'), 
    min_weight=pd.NamedAgg(column='weight', aggfunc='min')
)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

It is even simpler for Series, just pass the aggfunc to a keyword argument.

df.groupby('kind')['height'].agg(max_height='max', min_height='min')    

      max_height  min_height
kind                        
cat          9.5         9.1
dog         34.0         6.0       

Lastly, if your column names aren't valid python identifiers, use a dictionary with unpacking:

df.groupby('kind')['height'].agg(**{'max height': 'max', ...})

Pandas < 0.25

In more recent versions of pandas leading upto 0.24, if using a dictionary for specifying column names for the aggregation output, you will get a FutureWarning:

df.groupby('dummy').agg({'returns': {'Mean': 'mean', 'Sum': 'sum'}})
# FutureWarning: using a dict with renaming is deprecated and will be removed 
# in a future version

Using a dictionary for renaming columns is deprecated in v0.20. On more recent versions of pandas, this can be specified more simply by passing a list of tuples. If specifying the functions this way, all functions for that column need to be specified as tuples of (name, function) pairs.

df.groupby("dummy").agg({'returns': [('op1', 'sum'), ('op2', 'mean')]})

        returns          
            op1       op2
dummy                    
1      0.328953  0.032895

Or,

df.groupby("dummy")['returns'].agg([('op1', 'sum'), ('op2', 'mean')])

            op1       op2
dummy                    
1      0.328953  0.032895

DotNetCoders has a starter article on it: http://www.dotnetcoders.com/web/Articles/ShowArticle.aspx?article=50. They talk about how to set up the switches in the configuration file and how to write the code, but it is pretty old (2002).

There's another article on CodeProject: A Treatise on Using Debug and Trace classes, including Exception Handling, but it's the same age.

CodeGuru has another article on custom TraceListeners: Implementing a Custom TraceListener

The git-cache-meta mentioned in SO question "git - how to recover the file permissions git thinks the file should be?" (and the git FAQ) is the more staightforward approach.

The idea is to store in a .git_cache_meta file the permissions of the files and directories.
It is a separate file not versioned directly in the Git repo.

That is why the usage for it is:

$ git bundle create mybundle.bdl master; git-cache-meta --store
$ scp mybundle.bdl .git_cache_meta machine2: 
#then on machine2:
$ git init; git pull mybundle.bdl master; git-cache-meta --apply

So you:

• bundle your repo and save the associated file permissions.
• copy those two files on the remote server
• restore the repo there, and apply the permission

@tredder solution with editing applicationHost.config is the one that works if you have several different applications located within virtual directories on IIS.

My case is:

• I do have API project and APP project, under the same domain, placed in different virtual directories
• Root page XXX doesn't seem to propagate ASPNETCORE_ENVIRONMENT variable to its children in virtual directories and...
• ...I'm unable to set the variables inside the virtual directory as @NickAb described (got error The request is not supported. (Exception from HRESULT: 0x80070032) during saving changes in Configuration Editor):

• Going into applicationHost.config and manually creating nodes like this:

  <location path="XXX/app"> <system.webServer> <aspNetCore> <environmentVariables> <clear /> <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" /> </environmentVariables> </aspNetCore> </system.webServer> </location> <location path="XXX/api"> <system.webServer> <aspNetCore> <environmentVariables> <clear /> <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" /> </environmentVariables> </aspNetCore> </system.webServer> </location>

and restarting the IIS did the job.

How about custom module based .htaccess script (like its used in CodeIgniter)? I tried and it worked good in CodeIgniter apps. Any ideas to use it on other apps?

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

Yes DOK has the right answer ... either pre-sort the results before you write the HTML (assuming it's dynamic and you are responsible for the output), or you write javascript.

The Javascript Sort method will be your friend here. Simply pull the values out of the select list, then sort it, and put them back :-)

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
    string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with foreach or for any GridView event like OnRowDataBound.

Here you can input multiple values for DataKeyNames by separating with comma ,. For example, DataKeyNames="ProductID,ItemID,OrderID".

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

if you don't want or need a typed object try:

using Newtonsoft.Json;
// ...   
dynamic json  = JsonConvert.DeserializeObject(str);

or try for a typed object try:

Foo json  = JsonConvert.DeserializeObject<Foo>(str)

A 'button' is just that, a button, to which you can add additional functionality using Javascript. A 'submit' input type has the default functionality of submitting the form it's placed in (though, of course, you can still add additional functionality using Javascript).

I needed an iframe that would embed a portion of an external page with a vertical scroll bar, cropping out the navigation menus on the top and left of the page. I was able to do it with some simple HTML and CSS.

HTML

<div id="container">
    <iframe id="embed" src="http://www.example.com"></iframe>
</div>

CSS

div#container
{
    width:840px;
    height:317px;
    overflow:scroll;     /* if you don't want a scrollbar, set to hidden */
    overflow-x:hidden;   /* hides horizontal scrollbar on newer browsers */

    /* resize and min-height are optional, allows user to resize viewable area */
    -webkit-resize:vertical; 
    -moz-resize:vertical;
    resize:vertical;
    min-height:317px;
}

iframe#embed
{
    width:1000px;       /* set this to approximate width of entire page you're embedding */
    height:2000px;      /* determines where the bottom of the page cuts off */
    margin-left:-183px; /* clipping left side of page */
    margin-top:-244px;  /* clipping top of page */
    overflow:hidden;

    /* resize seems to inherit in at least Firefox */
    -webkit-resize:none;
    -moz-resize:none;
    resize:none;
}

ArrayList<Matrices> list = new ArrayList<Matrices>();
list.add( new Matrices(1,1,10) );
list.add( new Matrices(1,2,20) );

You could simply have just done:

var varAppend = "?single";
window.location.href = window.location.href.replace(".com",".com" + varAppend);

Unlike the other answers provided, there is no needless conditional check. If you design your project properly, you'll let the interface make the decision making and calling that statement whenever an event has been triggered.

Since there will only be one ".com" in your url, it will just replace .com with .com?single. I just added varAppend just in case you want to make it easier to modify the code in the future with different kinds of url variables.

One other note: The .replace works by adding to the href since href returns a string containing the full url address information.

Use this simple line:

int x = int.Parse(Console.ReadLine());

You can also create your own middleware function like

app.use( function(req, res, next) {
  // your code 
  next();
})

It contains three parameters req, res, next
You can also use it for authentication and validation of input params to keep your controller clean.

next() is used for go to next middleware or route.
You can send the response from middleware

i uses Js function replace simply.

<Text>{item.excerpt.rendered.replace(/<\/?[^>]+(>|$)/g, "")}</Text>

A bit simpler one-liner:

import os
from itertools import product, chain

chain.from_iterable([[os.sep.join(w) for w in product([i[0]], i[2])] for i in os.walk(dir)])

Think of REST as an architectural "class" while RESTful is the well known "instance" of that class.

Please mind the ""; we are not dealing with "real" programming objects here.

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

If you want to copy all contents of source directory recursively then you need to pass recursive option as true and try catch is documented way by fs-extra for sync

As fs-extra is complete replacement of fs so you don't need to import the base module

const fs = require('fs-extra');
let sourceDir = '/tmp/src_dir';
let destDir = '/tmp/dest_dir';
try {
  fs.copySync(sourceDir, destDir, { recursive: true })
  console.log('success!')
} catch (err) {
  console.error(err)
}

Desired capabilities comes in handy while doing remote or parallel execution using selenium grid. We will be parametrizing the browser details and passing in to selenium server using desired capabilities class.

Another usage is, test automation using Appium as shown below

// Created object of DesiredCapabilities class. 
DesiredCapabilities capabilities = new DesiredCapabilities(); 
// Set android deviceName desired capability. Set your device name. 
capabilities.setCapability("deviceName", "your Device Name"); 
// Set BROWSER_NAME desired capability. 
capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome"); 
// Set android VERSION desired capability. Set your mobile device's OS version. 
capabilities.setCapability(CapabilityType.VERSION, "5.1"); 
// Set android platformName desired capability. It's Android in our case here. 
capabilities.setCapability("platformName", "Android"); 

You can use jQuery to get text in textbox (work well for me), check in image detail

Code:

$(document.evaluate( "xpath" ,document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue).val()

Example: 
$(document.evaluate( "//*[@id='mail']" ,document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue).val()

Inject this above query to your code. Image detail:

If you wanna find a string in a vector:

    struct isEqual
{
    isEqual(const std::string& s): m_s(s)
    {}

    bool operator()(OIDV* l)
    {
        return l->oid == m_s;
    }

    std::string m_s;
};
struct OIDV
{
    string oid;
//else
};
VecOidv::iterator itFind=find_if(vecOidv.begin(),vecOidv.end(),isEqual(szTmp));

 WHERE cast(timestamp as date) = '2012-05-05'

=ROUND((TODAY()-A1)/365,0) will provide number of years between date in cell A1 and today's date

You need read.csv("C:/somedirectory/some/file.csv") and in general it doesn't hurt to actually look at the help page including its example section at the bottom.

This will return number of occurance of N

select ColumnName, LEN(ColumnName)- LEN(REPLACE(ColumnName, 'N', '')) from Table

After generating ctags, you can also use the following in vim:

:tag <f_name>

Above will take you to function definition.

Maybe this is what you are looking for. To check if a file exist and is not a link.

Try this command:

file="/usr/mda" 
[ -f $file ] && [ ! -L $file ] && echo "$file exists and is not a symlink"

Following command will remote origin current fork is referring to

git remote -v

For adding a remote path,

git remote add origin path_name

placing the WIFI as the first adapter [MTDesktop, AllowALL] and the LAN WIRED [MTServer,AllowAll] as the second adapter. In the Guest machine I disable the First Adapter in Adapter Settings. I can then ping internal, external whatever.

git apply --reverse --reject example.patch

When you created a patch file with the branch names reversed:

ie. git diff feature_branch..master instead of git diff master..feature_branch

LayoutParams lparams = new LayoutParams(
   LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
TextView tv=new TextView(this);
tv.setLayoutParams(lparams);
tv.setText("test");
this.m_vwJokeLayout.addView(tv);

You can change lparams according to your needs

echo $(date +%d/%h/%y) date_today
echo " The other date is 1970/01/01"
TODAY_DATE="1970-01-01"
BEFORE_DATE=$(date +%d%h%y)
echo "THE DIFFERNS IS " $(( ($(date -d $BEFORE_DATE +%s) - $(date -d $TODAY_DATE +%s)) )) SECOUND

use it to get your date today and your sec since the date you want. if you want it with days just divide it with 86400

echo $(date +%d/%h/%y) date_today
echo " The other date is 1970/01/01"
TODAY_DATE="1970-01-01"
BEFORE_DATE=$(date +%d%h%y)
echo "THE DIFFERNS IS " $(( ($(date -d $BEFORE_DATE +%s) - $(date -d $TODAY_DATE +%s))/ 86400)) SECOUND

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

string strHeader = Request.Headers["XYZComponent"]
bool bHeader = Boolean.TryParse(strHeader, out bHeader ) && bHeader;

if "true" than true
if "false" or anything else ("fooBar") than false

or

string strHeader = Request.Headers["XYZComponent"]
bool b;
bool? bHeader = Boolean.TryParse(strHeader, out b) ? b : default(bool?);

if "true" than true
if "false" than false
else ("fooBar") than null

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

I was attempting something similar, and the RoboSpice example helped me work it out:

HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");

HttpEntity<String> request = new HttpEntity<>(input, createHeader());

String url = "http://awesomesite.org";
Uri.Builder uriBuilder = Uri.parse(url).buildUpon();
uriBuilder.appendQueryParameter(key, value);
uriBuilder.appendQueryParameter(key, value);
...

String url = uriBuilder.build().toString();

HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, request , String.class);

// The letter "t" is usually letter "i"//

    for(t=0;t<x[t];t++)
    {

         printf(" %2d          || %7d \n ",t,x[t]);
    }

Another method that worked for me on Windows 7 that did not require administrative privileges:

Click on the Start menu, search for "environment," click "Edit environment variables for your account."

In the window that opens, select "PATH" under "User variables for username" and click the "Edit..." button. Add your new path to the end of the existing Path, separated by a semi-colon (%PATH%;C:\Python27;...;C:\NewPath). Click OK on all the windows, open a new CMD window, and test the new variable.

class EnumHelpers {

    static getNamesAndValues<T extends number>(e: any) {
        return EnumHelpers.getNames(e).map(n => ({ name: n, value: e[n] as T }));
    }

    static getNames(e: any) {
        return EnumHelpers.getObjValues(e).filter(v => typeof v === 'string') as string[];
    }

    static getValues<T extends number>(e: any) {
        return EnumHelpers.getObjValues(e).filter(v => typeof v === 'number') as T[];
    }

    static getSelectList<T extends number, U>(e: any, stringConverter: (arg: U) => string) {
        const selectList = new Map<T, string>();
        this.getValues(e).forEach(val => selectList.set(val as T, stringConverter(val as unknown as U)));
        return selectList;
    }

    static getSelectListAsArray<T extends number, U>(e: any, stringConverter: (arg: U) => string) {
        return Array.from(this.getSelectList(e, stringConverter), value => ({ value: value[0] as T, presentation: value[1] }));
    }

    private static getObjValues(e: any): (number | string)[] {
        return Object.keys(e).map(k => e[k]);
    }
}

This is what I use:

import os, sys
sys.path.append(os.path.join(os.path.dirname(__file__), "lib"))

sed will need to read the data too to count the lines. The only way a shortcut would be possible would there to be context/order in the file to operate on. For example if there were log lines prepended with a fixed width time/date etc. you could use the look unix utility to binary search through the files for particular dates/times

Connection object is for illustration only. The DataAdapter is the key bit:

Dim strSql As String = "SELECT EmpCode,EmpID,EmpName FROM dbo.Employee"
Dim dtb As New DataTable
Using cnn As New SqlConnection(connectionString)
  cnn.Open()
  Using dad As New SqlDataAdapter(strSql, cnn)
    dad.Fill(dtb)
  End Using
  cnn.Close()
End Using

To get size of emf file without EMF Image Reader you can use code:

Dimension getImageDimForEmf(final String path) throws IOException {

    ImageInputStream inputStream = new FileImageInputStream(new File(path));

    inputStream.setByteOrder(ByteOrder.LITTLE_ENDIAN);

    // Skip magic number and file size
    inputStream.skipBytes(6*4);

    int left   = inputStream.readInt();
    int top    = inputStream.readInt();
    int right  = inputStream.readInt();
    int bottom = inputStream.readInt();

    // Skip other headers
    inputStream.skipBytes(30);

    int deviceSizeInPixelX = inputStream.readInt();
    int deviceSizeInPixelY = inputStream.readInt();

    int deviceSizeInMlmX = inputStream.readInt();
    int deviceSizeInMlmY = inputStream.readInt();

    int widthInPixel = (int) Math.round(0.5 + ((right - left + 1.0) * deviceSizeInPixelX / deviceSizeInMlmX) / 100.0);
    int heightInPixel = (int) Math.round(0.5 + ((bottom-top + 1.0) * deviceSizeInPixelY / deviceSizeInMlmY) / 100.0);

    inputStream.close();

    return new Dimension(widthInPixel, heightInPixel);
}

In LINQ you could do something like:

foreach (var data in from DataRow row in dataTable.Rows
                     from DataColumn col in dataTable.Columns
                          where
                              row[col] != null
                          select row[col])
{
    // do something with data
}

None of the answers worked for me because all my HTML was in a single line.

Basically you need first to break each line with the following command that substitutes >< with the same characters but with a line break in the middle.

:%s/></>\r</g

Then the command

gg=G

will indent the file.

Looping through all the files in the folder is relatively easy:

files = dir('*.csv');
for file = files'
    csv = load(file.name);
    % Do some stuff

To avoid the fact that destroy_all instantiates all the records and destroys them one at a time, you can use it directly from the model class.

So instead of :

u = User.find_by_name('JohnBoy')
u.usage_indexes.destroy_all

You can do :

u = User.find_by_name('JohnBoy')
UsageIndex.destroy_all "user_id = #{u.id}"

The result is one query to destroy all the associated records

There's nothing wrong with your code, the following works fine for me when I have the file.txt in the user.dir directory.

import java.io.File;
import java.util.Scanner;

public class testme {
    public static void main(String[] args) {
        System.out.println(System.getProperty("user.dir"));
        File file = new File("file.txt");
        try {
            Scanner scanner = new Scanner(file);
        } catch (Exception e) {
        System.out.println(e);
        }
    }
}

Don't trust Eclipse with where it says the file is. Go out to the actual filesystem with Windows Explorer or equivalent and check.

Based on your edit, I think we need to see your import statements as well.

You can use the formula INDIRECT().

This basically takes a string and treats it as a reference. In your case, you would use:

=INDIRECT("'"&A5&"'!G7")

The double quotes are to show that what's inside are strings, and only A5 here is a reference.

For having a language at Visual Studio Ui , basically the language package of that language must be installed during the installation.

You can not select a language in options -> environment -> international settings that didn't installed.

If the language that you want to select in above path is not appearing than you have to modify your visual studio by re-executing installer and selecting Language Packages tab and check your language that you want to have.

And than at Visual Studio toolbar just click Tools --> Options --> Environment --> International Settings and than select your language from dropdown list.

Yes it is simple to do.

Sub CompactRepair()
  Dim control As Office.CommandBarControl

Basically it just finds the "Compact and repair" menuitem and clicks it, programatically.

is the preferred, pythonic version. Use of has_key() is discouraged, and this method has been removed in Python 3.

There is probably a way (or three) to do this... however, I see one issue with your goal: how do you know when all the files have been uploaded? To rephrase in a way that makes more sense... how do you know what "all" means? According to the documentation, init gets called at the initialization of the Dropzone itself, and then you set up the complete event handler to do something when each file that's uploaded is complete. But, what mechanism is the user given to allow the program to know when he's dropped all the files he's intended to drop? If you are assuming that he/she will do a batch drop (i.e., drop onto the Dropzone 2-whatever number of files, at once, in one drop action), then the following code could/possibly should work:

Dropzone.options.filedrop = {
    maxFilesize: 4096,
    init: function () {
        var totalFiles = 0,
            completeFiles = 0;
        this.on("addedfile", function (file) {
            totalFiles += 1;
        });
        this.on("removed file", function (file) {
            totalFiles -= 1;
        });
        this.on("complete", function (file) {
            completeFiles += 1;
            if (completeFiles === totalFiles) {
                doSomething();
            }
        });
    }
};

Basically, you watch any time someone adds/removes files from the Dropzone, and keep a count in closure variables. Then, when each file download is complete, you increment the completeFiles progress counter var, and see if it now equals the totalCount you'd been watching and updating as the user placed things in the Dropzone. (Note: never used the plug-in/JS lib., so this is best guess as to what you could do to get what you want.)

for iTunes 12 and above (Yosemite) double click on IPA then browse your iOS device, on applist you will see the app, click the install on item.

Can you try this?

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE CAST(Submission_date AS DATE) = CAST(GETDATE() AS DATE)

T-SQL doesn't really have the "implied" casting like C# does - you need to explicitly use CAST (or CONVERT).

Also, use GETDATE() or CURRENT_TIMESTAMP to get the "now" date and time.

Update: since you're working against SQL Server 2000 - none of those approaches so far work. Try this instead:

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE DATEADD(dd, 0, DATEDIFF(dd, 0, submission_date)) = DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))

On your solution explorer window, right click to References, select Add Reference, go to .NET tab, find and add Microsoft.CSharp.

Alternatively add the Microsoft.CSharp NuGet package.

Install-Package Microsoft.CSharp

Alternatively there's the application called LiveReload...

I'm afraid that's not possible. the rgba format you know is the only one.

The question is a few months old but for other people looking --

A simpler way to import a large file is to make a sub directory 'upload' in your folder c:/wamp/apps/phpmyadmin3.5.2 and edit this line in the config.inc.php file in the same directory to include the folder name $cfg['UploadDir'] = 'upload';

Then place the incoming .sql file in the folder /upload.

Working from inside the phpmyadmin console, go to the new database and import. You will now see an additional option to upload files from that folder. Chose the correct file and be a little patient. It works.

If you still get a time out error try adding $cfg['ExecTimeLimit'] = 0; to the same config.inc.php file.

I have had difficulty importing an .sql file where the user name was root and the password differed from my the root password on my new server. I simply took off the password before I exported the .sql file and the import worked smoothly.

You can use ng-value-true to tell angular that your ng-model is a string.

I could only get ng-true-value working if I added the extra quotes like so (as shown in the official Angular docs - https://docs.angularjs.org/api/ng/input/input%5Bcheckbox%5D)

ng-true-value="'1'"

Too late, just in case some one is looking for another way:

void Main()
{
    string jsonString = @"{
  'Stores': [
    'Lambton Quay',
    'Willis Street'
  ],
  'Manufacturers': [
    {
      'Name': 'Acme Co',
      'Products': [
        {
          'Name': 'Anvil',
          'Price': 50
        }
      ]
    },
    {
      'Name': 'Contoso',
      'Products': [
        {
          'Name': 'Elbow Grease',
          'Price': 99.95
        },
        {
          'Name': 'Headlight Fluid',
          'Price': 4
        }
      ]
    }
  ]
}";

    Product product = new Product();
    //Serializing to Object
    Product obj = JObject.Parse(jsonString).SelectToken("$.Manufacturers[?(@.Name == 'Acme Co' && @.Name != 'Contoso')]").ToObject<Product>();

    Console.WriteLine(obj);
}


public class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
}

Share Any File as below ( Kotlin ) :
first create a folder named xml in the res folder and create a new XML Resource File named provider_paths.xml and put the below code inside it :

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path
        name="files"
        path="."/>

    <external-path
        name="external_files"
        path="."/>
</paths>

now go to the manifests folder and open the AndroidManifest.xml and then put the below code inside the <application> tag :

<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
    android:name="android.support.FILE_PROVIDER_PATHS"
    android:resource="@xml/provider_paths" /> // provider_paths.xml file path in this example
</provider>

now you put the below code in the setOnLongClickListener :

share_btn.setOnClickListener {
    try {
        val file = File("pathOfFile")
        if(file.exists()) {
            val uri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", file)
            val intent = Intent(Intent.ACTION_SEND)
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
            intent.setType("*/*")
            intent.putExtra(Intent.EXTRA_STREAM, uri)
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent)
        }
    } catch (e: java.lang.Exception) {
        e.printStackTrace()
        toast("Error")
    }
}

A working jQuery validate example:

   $(function () {
        $('input[type=file]').on('change', function() {
            var $el = $(this);
            var files = this.files;
            var image = new Image();
            image.onload = function() {
                $el
                    .attr('data-upload-width', this.naturalWidth)
                    .attr('data-upload-height', this.naturalHeight);
            }

            image.src = URL.createObjectURL(files[0]);
        });

        jQuery.validator.unobtrusive.adapters.add('imageminwidth', ['imageminwidth'], function (options) {
            var params = {
                imageminwidth: options.params.imageminwidth.split(',')
            };

            options.rules['imageminwidth'] = params;
            if (options.message) {
                options.messages['imageminwidth'] = options.message;
            }
        });

        jQuery.validator.addMethod("imageminwidth", function (value, element, param) {
            var $el = $(element);
            if(!element.files && element.files[0]) return true;
            return parseInt($el.attr('data-upload-width')) >=  parseInt(param["imageminwidth"][0]);
        });

    } (jQuery));

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

In my case I tried all the tips suggested but the error remained. I solved changing with a more recent version and writing that in the pom.xml. After this everything is now ok.

The most clean and modern way to use singletons in Android is just to use the Dependency Injection framework called Dagger 2. Here you have an explanation of possible scopes you can use. Singleton is one of these scopes. Dependency Injection is not that easy but you shall invest a bit of your time to understand it. It also makes testing easier.

You need something like:

    URL resource = this.getClass().getResource("/path/to/resource.res");
    File is = null;
    try {
        is = new File(resource.toURI());
    } catch (URISyntaxException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    try {
        FileInputStream input = new FileInputStream(is);
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

But it will work only within your IDE, not in runnable JAR. I had same problem explained here.

public function index() {

    $user = $this->session->userdata("username");
    $file_path = "./images/" . $user . '/';

    if (isset($_FILES['multipleUpload'])) {

        if (!is_dir('images/' . $user)) {
            mkdir('./images/' . $user, 0777, TRUE);
        }

        $files = $_FILES;
        $cpt = count($_FILES ['multipleUpload'] ['name']);

        for ($i = 0; $i < $cpt; $i ++) {

            $name = time().$files ['multipleUpload'] ['name'] [$i];
            $_FILES ['multipleUpload'] ['name'] = $name;
            $_FILES ['multipleUpload'] ['type'] = $files ['multipleUpload'] ['type'] [$i];
            $_FILES ['multipleUpload'] ['tmp_name'] = $files ['multipleUpload'] ['tmp_name'] [$i];
            $_FILES ['multipleUpload'] ['error'] = $files ['multipleUpload'] ['error'] [$i];
            $_FILES ['multipleUpload'] ['size'] = $files ['multipleUpload'] ['size'] [$i];

            $this->upload->initialize($this->set_upload_options($file_path));
            if(!($this->upload->do_upload('multipleUpload')) || $files ['multipleUpload'] ['error'] [$i] !=0)
            {
                print_r($this->upload->display_errors());
            }
            else
            {
                $this->load->model('uploadModel','um');
                $this->um->insertRecord($user,$name);
            }
        }
    } else {
        $this->load->view('uploadForm');
    }
}

public function set_upload_options($file_path) {
    // upload an image options
    $config = array();
    $config ['upload_path'] = $file_path;
    $config ['allowed_types'] = 'gif|jpg|png';
    return $config;
}

If you want all the dependencies in a single file at the end within two steps. Add this to your build.gradle.kts in the root of your project:

project.rootProject.allprojects {
    apply(plugin="project-report")

    this.task("allDependencies", DependencyReportTask::class) {
        evaluationDependsOnChildren()
        this.setRenderer(AsciiDependencyReportRenderer())
    }

}

Then apply:

./gradlew allDependencies | grep '\-\-\-' | grep -Po '\w+.*$' | awk -F ' ' '{ print $1 }' | sort | grep -v '\{' | grep -v '\[' | uniq | grep '.\+:.\+:.\+'

This will give you all the dependencies in your project and sub-projects along with all the 3rd party dependencies.

If you want to get this done in a programmatic way, then you'll need a custom renderer of the dependencies - you can start by extending the AsciiDependencyReportRenderer that prints an ascii graph of the dependencies by default.

I've had issues with using SELECT last_insert_rowid() in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.

Here's where they state that in the doco:

If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.

That's from sqlite.org doco

Just another bit. in some case i found no result on all_tab_privs! i found it indeed on dba_tab_privs. I think so that this last table is better to check for any grant available on an object (in case of impact analysis). The statement becomes:

    select * from dba_tab_privs where table_name = 'sequence_name';

There are multiple options to set variables in Hive.

If you're looking to set Hive variable from inside the Hive shell, you can set it using hivevar. You can set string or integer datatypes. There are no problems with them.

SET hivevar:which_date=20200808;
select ${which_date};

If you're planning to set variables from shell script and want to pass those variables into your Hive script (HQL) file, you can use --hivevar option while calling hive or beeline command.

# shell script will invoke script like this
beeline --hivevar tablename=testtable -f select.hql

-- select.hql file
select * from <dbname>.${tablename};

Use

window.history.replaceState({}, document.title, updatedUri);

To update Url without reloading the page

 var url = window.location.href;
 var urlParts = url.split('?');
 if (urlParts.length > 0) {
     var baseUrl = urlParts[0];
     var queryString = urlParts[1];

     //update queryString in here...I have added a new string at the end in this example
     var updatedQueryString = queryString + 'this_is_the_new_url' 

     var updatedUri = baseUrl + '?' + updatedQueryString;
     window.history.replaceState({}, document.title, updatedUri);
 }

To remove Query string without reloading the page

var url = window.location.href;
if (url.indexOf("?") > 0) {
     var updatedUri = url.substring(0, url.indexOf("?"));
     window.history.replaceState({}, document.title, updatedUri);
}

(Just assumption, less info of Exception stacktrace)

I think, this line, incercari.setText(valIncercari); throws Exception because valIncercari is int

So it should be,

incercari.setText(valIncercari+"");

Or

incercari.setText(Integer.toString(valIncercari));

A quick one-liner.

list_a = [5,4,3,2,1]
list_b = [1,1.5,1.75,2,3,3.5,3.75,4,5]

Say you want list a to match list b.

orderedList =  sorted(list_a, key=lambda x: list_b.index(x))

This is helpful when needing to order a smaller list to values in larger. Assuming that the larger list contains all values in the smaller list, it can be done.

Left Shift

x = x * 2^value (normal operation)

x << value (bit-wise operation)

x = x * 16 (which is the same as 2^4)

The left shift equivalent would be x = x << 4

Right Shift

x = x / 2^value (normal arithmetic operation)

x >> value (bit-wise operation)

x = x / 8 (which is the same as 2^3)

The right shift equivalent would be x = x >> 3

Renaming a worksheet manually in Excel, you hit a limit of 31 chars, so I'd suggest that that's a hard limit.

Here is some code that will manage your MongoDB connections.

var MongoClient = require('mongodb').MongoClient;
var url = require("../config.json")["MongoDBURL"]

var option = {
  db:{
    numberOfRetries : 5
  },
  server: {
    auto_reconnect: true,
    poolSize : 40,
    socketOptions: {
        connectTimeoutMS: 500
    }
  },
  replSet: {},
  mongos: {}
};

function MongoPool(){}

var p_db;

function initPool(cb){
  MongoClient.connect(url, option, function(err, db) {
    if (err) throw err;

    p_db = db;
    if(cb && typeof(cb) == 'function')
        cb(p_db);
  });
  return MongoPool;
}

MongoPool.initPool = initPool;

function getInstance(cb){
  if(!p_db){
    initPool(cb)
  }
  else{
    if(cb && typeof(cb) == 'function')
      cb(p_db);
  }
}
MongoPool.getInstance = getInstance;

module.exports = MongoPool;

When you start the server, call initPool

require("mongo-pool").initPool();

Then in any other module you can do the following:

var MongoPool = require("mongo-pool");
MongoPool.getInstance(function (db){
    // Query your MongoDB database.
});

This is based on MongoDB documentation. Take a look at it.

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

if you are making a RecyclerView and using an adapter, what worked for me was:

@Override
public void onBindViewHolder(ADAPTERVIEWHOLDER holder, int position) {
    MODEL model = LIST.get(position);
    holder.TEXTVIEW.setText(service.getTitle());
    holder.TEXTVIEW.setText(service.getDesc());

    Context context = holder.IMAGEVIEW.getContext();
    Picasso.with(context).load(model.getImage()).into(holder.IMAGEVIEW);
}

For an IIS MVC 5 / Angular CLI ( Yes, I am well aware your problem is with Angular JS ) project with API I did the following:

That should fix your issues for both MVC and WebAPI without having to do all the other run around. I then created an HttpInterceptor in the Angular CLI project that automatically added in the the relevant header information. Hope this helps someone out in a similar situation.

What really worked to me: (source: oracle documentation "reading url")

 import java.net.*;
 import java.io.*;

 public class UrlTextfile {
public static void main(String[] args) throws Exception {

    URL oracle = new URL("http://yoursite.com/yourfile.txt");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(oracle.openStream()));

    String inputLine;
    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);
    in.close();
}
 }

Have you tried moving DEL %FILE%.txt% to after @echo %FILE% deleted. >> results.txt so that it looks like this?

@echo %FILE% deleted. >> results.txt
DEL %FILE%.txt

I ran this on MacOS /Applications/Python\ 3.6/Install\ Certificates.command

It is Yoda condition writing in different manner

In java

String myString = null;
if (myString.equals("foobar")) { /* ... */ } //Will give u null pointer

yoda condition

String myString = null;
if ("foobar".equals(myString)) { /* ... */ } // will be false 

Depends what you mean by a pattern. If you're thinking Person/Company/Transaction/Product and such, then yes - there are a lot of generic database schemas already available.

If you're thinking Factory, Singleton... then no - you don't need any of these as they're too low level for DB programming.

If you're thinking database object naming, then it's under the category of conventions, not design per se.

BTW, S.Lott, one-to-many and many-to-many relationships aren't "patterns". They're the basic building blocks of the relational model.

lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")...]

msg = filter(lambda x : x != "8", lst)

print msg

EDIT: For anyone who came across this post, just for understanding the above removes any elements from the list which are equal to 8.

Supposing we use the above example the first element ("aaaaa8") would not be equal to 8 and so it would be dropped.

To make this (kinda work?) with how the intent of the question was we could perform something similar to this

msg = filter(lambda x: x != "8", map(lambda y: list(y), lst))

• I am not in an interpreter at the moment so of course mileage may vary, we may have to index so we do list(y[0]) would be the only modification to the above for this explanation purposes.

What this does is split each element of list up into an array of characters so ("aaaa8") would become ["a", "a", "a", "a", "8"].

This would result in a data type that looks like this

msg = [["a", "a", "a", "a"], ["b", "b"]...]

So finally to wrap that up we would have to map it to bring them all back into the same type roughly

msg = list(map(lambda q: ''.join(q), filter(lambda x: x != "8", map(lambda y: list(y[0]), lst))))

I would absolutely not recommend it, but if you were really wanting to play with map and filter, that would be how I think you could do it with a single line.

What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud

and

https://github.com/melardev/ApiAspCoreEcommerce

here is how the class looks like(go to my repo for full code):

public class StatusCodeAndDtoWrapper : ObjectResult
{



    public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
    {
        StatusCode = statusCode;
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
    {
        StatusCode = statusCode;
        if (dto.FullMessages == null)
            dto.FullMessages = new List<string>(1);
        dto.FullMessages.Add(message);
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
    {
        StatusCode = statusCode;
        dto.FullMessages = messages;
    }
}

Notice the base(dto) you replace dto by your object and you should be good to go.

java.lang does not contain a class called StringUtils. Several third-party libs do, such as Apache Commons Lang or the Spring framework. Make sure you have the relevant jar in your project classpath and import the correct class.

Aahh got it... I got it working :)

Thanks Christopher, your suggesion is correct.

But, finding "Default SMTP Virtual Server" was tricky ;)

Even if you use IIS7 to deploy your web site, you have to open IIS6 Manager to configure SMTP server (why?).

I configured SMTP server as follows to make things work:

1. Open IIS6 Manager using Control Panel --> Administrative Tools.
2. Open SMTP Virtual Server properties.
3. On General tab, Set IP address of the Web server instead of "All Unassigned".
4. In Access tab, click on Relay button, this will open Relay Restrictions dialog.
5. In relay computers list, add the loopback IP address i.e 127.0.0.1 and IP address of the Web server, so that they can pass/relay emails through the SMTP server.

In Selenium Python it is:

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.ui import Select

def get_selected_value_from_drop_down(self):
    try:
        select = Select(WebDriverWait(self.driver, 20).until(EC.element_to_be_clickable((By.ID, 'data_configuration_edit_data_object_tab_details_lb_use_for_match'))))
        return select.first_selected_option.get_attribute("value")
    except NoSuchElementException, e:
        print "Element not found "
        print e

if you use jquery on you website, you can use something like this your console

$.post(_x000D_
    'dom/data-home.php',_x000D_
    {_x000D_
    type : "home", id : "0"_x000D_
    },function(data){_x000D_
        console.log(data)_x000D_
    })

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>

Java SE 6 or Java EE 5 provides a method to do this now so there is no need for extra libraries.

The method is DatatypeConverter.parseHexBinary

In this case it can be used as follows:

String str = "9B7D2C34A366BF890C730641E6CECF6F";
byte[] bytes = DatatypeConverter.parseHexBinary(str);

The class also provides type conversions for many other formats that are generally used in XML.

I would do the folowing:

Declare separetly the enum, in it´s own file:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { this.value = value; }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

Declare a new JPA entity named Right

@Entity
public class Right{
    @Id
    private Integer id;
    //FIElDS

    // constructor
    public Right(RightEnum rightEnum){
          this.id = rightEnum.getValue();
    }

    public Right getInstance(RightEnum rightEnum){
          return new Right(rightEnum);
    }


}

You will also need a converter for receiving this values (JPA 2.1 only and there´s a problem I´ll not discuss here with these enum´s to be directly persisted using the converter, so it will be a one way road only)

import mypackage.RightEnum;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

/**
 * 
 * 
 */
@Converter(autoApply = true)
public class RightEnumConverter implements AttributeConverter<RightEnum, Integer>{

    @Override //this method shoudn´t be used, but I implemented anyway, just in case
    public Integer convertToDatabaseColumn(RightEnum attribute) {
        return attribute.getValue();
    }

    @Override
    public RightEnum convertToEntityAttribute(Integer dbData) {
        return RightEnum.valueOf(dbData);
    }

}

The Authority entity:

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;

  // the **Entity** to map : 
  private Right right;

  // the **Enum** to map (not to be persisted or updated) : 
  @Column(name="COLUMN1", insertable = false, updatable = false)
  @Convert(converter = RightEnumConverter.class)
  private RightEnum rightEnum;

}

By doing this way, you can´t set directly to the enum field. However, you can set the Right field in Authority using

autorithy.setRight( Right.getInstance( RightEnum.READ ) );//for example

And if you need to compare, you can use:

authority.getRight().equals( RightEnum.READ ); //for example

Which is pretty cool, I think. It´s not totally correct, since the converter it´s not intended to be use with enum´s. Actually, the documentation says to never use it for this purpose, you should use the @Enumerated annotation instead. The problem is that there are only two enum types: ORDINAL or STRING, but the ORDINAL is tricky and not safe.

However, if it doesn´t satisfy you, you can do something a little more hacky and simpler (or not).

Let´s see.

The RightEnum:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { 
            try {
                  this.value= value;
                  final Field field = this.getClass().getSuperclass().getDeclaredField("ordinal");
                  field.setAccessible(true);
                  field.set(this, value);
             } catch (Exception e) {//or use more multicatch if you use JDK 1.7+
                  throw new RuntimeException(e);
            }
      }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

and the Authority entity

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;


  // the **Enum** to map (to be persisted or updated) : 
  @Column(name="COLUMN1")
  @Enumerated(EnumType.ORDINAL)
  private RightEnum rightEnum;

}

In this second idea, its not a perfect situation since we hack the ordinal attribute, but it´s a much smaller coding.

I think that the JPA specification should include the EnumType.ID where the enum value field should be annotated with some kind of @EnumId annotation.

SQL Server default port is 1434.

To allow remote access I had to release those ports on my firewall:

Protocol  |   Port
---------------------
UDP       |   1050
TCP       |   1050
TCP       |   1433
UDP       |   1434

http://php.net/manual/en/language.types.array.php

<?php
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];
?>

Standard arrays can be used that way.

Are you sure that the data stored in the database is actually a question mark? I would tend to suspect from the sample data that the problem is one of character set conversion where ? is being used as the replacement character when the character can't be represented in the client character set. Possibly, the database is actually storing Microsoft "smart quote" characters rather than simple apostrophes.

What does the DUMP function show is actually stored in the database?

SELECT column_name,
       dump(column_name,1016)
  FROM your_table
 WHERE <<predicate that returns just the sample data you posted>>

What application are you using to view the data? What is the client's NLS_LANG set to?

What is the database and national character set? Is the data stored in a VARCHAR2 column? Or NVARCHAR2?

SELECT parameter, value
  FROM v$nls_parameters
 WHERE parameter LIKE '%CHARACTERSET';

If all the problem characters are stored in the database as 0x19 (decimal 25), your REPLACE would need to be something like

UPDATE table_name
   SET column1 = REPLACE(column1, chr(25), q'[']'),
       column2 = REPLACE(column2, chr(25), q'[']'),
       ...
       columnN = REPLACE(columnN, chr(25), q'[']')
 WHERE INSTR(column1,chr(25)) > 0
    OR INSTR(column2,chr(25)) > 0 
    ...
    OR INSTR(columnN,chr(25)) > 0

String.prototype.padStart() and String.prototype.padEnd() are currently TC39 candidate proposals: see github.com/tc39/proposal-string-pad-start-end (only available in Firefox as of April 2016; a polyfill is available).

You can use this code to find HyperLink in GridView. Use of e.Row.Cells[0].Controls[0] to find First position of control in GridView.

protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{    
  if(e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRowView v = (DataRowView)e.Row.DataItem;           

        if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
        {
            HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
            if (link != null)
            {                    
                    link.Text = "Edit";
            }               
        }       

    }
}

Laravel 5.8

{{ request()->a }}

Why did it take a lot of valgrind investigation to find this out! Just prove it to yourself with some simple code e.g.

std::vector<std::string> vec;

{
      std::string obj("hello world");
      vec.push_pack(obj);
}

std::cout << vec[0] << std::endl;  

If "hello world" is printed, the object must have been copied

A rather new project is the xml-coreutils package featuring xml-cat, xml-cp, xml-cut, xml-grep, ...

http://xml-coreutils.sourceforge.net/contents.html

I came up with such solution, works great for me:

msbuild /t:ResolveReferences;_WPPCopyWebApplication /p:BuildingProject=true;OutDir=C:\Temp\build\ Test.csproj

The secret sauce is _WPPCopyWebApplication target.

Your response is almost certainly a string. You need to make sure it gets converted to a number:

document.getElementById("points").value= new Number(request.responseText);

You might take a closer look at your responseText. It sound like you are getting a string that contains quotes. If you are getting JSON data via AJAX, you might have more consistent results running it through JSON.parse().

document.getElementById("points").value= new Number(JSON.parse(request.responseText));

You can use this.setResizable(false); or frameObject.setResizable(false);

Try iterator function

For example you can return first element

x = [['a',1],['b',2],['a',1]]

_.uniq(x,false,function(i){  

   return i[0]   //'a','b'

})

=> [['a',1],['b',2]]

I know this post is old, sorry for that.

You can also type 10x for cols and x2 for rows, if you want to have only one attribute.

[textarea* your-message x3 class:form-control] <!-- only rows -->
[textarea* your-message 10x class:form-control] <!-- only columns -->
[textarea* your-message 10x3 class:form-control] <!-- both -->

Regular expressions:

var numberPattern = /\d+/g;

'something102asdfkj1948948'.match( numberPattern )

This would return an Array with two elements inside, '102' and '1948948'. Operate as you wish. If it doesn't match any it will return null.

To concatenate them:

'something102asdfkj1948948'.match( numberPattern ).join('')

Assuming you're not dealing with complex decimals, this should suffice I suppose.

My solution via generator function is:

def divisor(num):
    for x in range(1, num + 1):
        if num % x == 0:
            yield x
    while True:
        yield None

Put your parameters in a hash table and pass them like this:

$postParams = @{username='me';moredata='qwerty'}
Invoke-WebRequest -Uri http://example.com/foobar -Method POST -Body $postParams

Postgres documentation describes the differences between UUIDs. A couple of them:

V3:

uuid_generate_v3(namespace uuid, name text) - This function generates a version 3 UUID in the given namespace using the specified input name.

V4:

uuid_generate_v4 - This function generates a version 4 UUID, which is derived entirely from random numbers.

Try this:

DELIMITER $$
CREATE TRIGGER occupy_trig
AFTER INSERT ON `OccupiedRoom` FOR EACH ROW
begin
       DECLARE id_exists Boolean;
       -- Check BookingRequest table
       SELECT 1
       INTO @id_exists
       FROM BookingRequest
       WHERE BookingRequest.idRequest= NEW.idRequest;

       IF @id_exists = 1
       THEN
           UPDATE BookingRequest
           SET status = '1'
           WHERE idRequest = NEW.idRequest;
        END IF;

DELIMITER ;

This is what worked for me:

import json
import requests
url = 'http://xxx.com'
payload = {'param': '1', 'data': '2', 'field': '4'}
headers = {'content-type': 'application/json'}
r = requests.post(url, data = json.dumps(payload), headers = headers)

If you're using a support library, you'll want to do something like this:

FragmentManager manager = getSupportFragmentManager();
Fragment fragment = manager.findFragmentById(R.id.my_fragment);
fragment.myMethod();

Setup a ts project as following steps:

• install typescript yarn global add typescript
• create a package.json: run yarn init or setting defaults yarn init -yp
• create a tsconfig.json: run tsc --init
• (*optional) add tslint.json

The project structure seems like:

¦  package.json
¦  tsconfig.json
¦  tslint.json
¦  yarn.lock
¦
+-dist
¦      index.js
¦
+-src
       index.ts

You can make use of df.as_matrix() function and create Numpy-array and pass it.

Y = df.pop()
X = df.as_matrix()
x_train, x_test, y_train, y_test = train_test_split(X, Y, test_size = 0.2)
model.fit(x_train, y_train)
model.test(x_test)

You have to first convert it into datetime, then to date.

Try this, it might be helpful:

Select Convert(DATETIME, LEFT(20130101, 8))

then convert to date.

$str = preg_replace('/[\s]+/', ' ', $str);

In my case ( XCode 7 and iOS 9 ), I use UINavigationController "hidden", so Ihave to add UINavigationControllerDelegate to present camera or roll and it work like it is supposed to! And pickerControllerDelegate.self doesn't display error either!

JavaScript is always synchronous and single-threaded. If you're executing a JavaScript block of code on a page then no other JavaScript on that page will currently be executed.

JavaScript is only asynchronous in the sense that it can make, for example, Ajax calls. The Ajax call will stop executing and other code will be able to execute until the call returns (successfully or otherwise), at which point the callback will run synchronously. No other code will be running at this point. It won't interrupt any other code that's currently running.

JavaScript timers operate with this same kind of callback.

Describing JavaScript as asynchronous is perhaps misleading. It's more accurate to say that JavaScript is synchronous and single-threaded with various callback mechanisms.

jQuery has an option on Ajax calls to make them synchronously (with the async: false option). Beginners might be tempted to use this incorrectly because it allows a more traditional programming model that one might be more used to. The reason it's problematic is that this option will block all JavaScript on the page until it finishes, including all event handlers and timers.

If your YAML file looks like this:

# tree format
treeroot:
    branch1:
        name: Node 1
        branch1-1:
            name: Node 1-1
    branch2:
        name: Node 2
        branch2-1:
            name: Node 2-1

And you've installed PyYAML like this:

pip install PyYAML

And the Python code looks like this:

import yaml
with open('tree.yaml') as f:
    # use safe_load instead load
    dataMap = yaml.safe_load(f)

The variable dataMap now contains a dictionary with the tree data. If you print dataMap using PrettyPrint, you will get something like:

{
    'treeroot': {
        'branch1': {
            'branch1-1': {
                'name': 'Node 1-1'
            },
            'name': 'Node 1'
        },
        'branch2': {
            'branch2-1': {
                'name': 'Node 2-1'
            },
            'name': 'Node 2'
        }
    }
}

So, now we have seen how to get data into our Python program. Saving data is just as easy:

with open('newtree.yaml', "w") as f:
    yaml.dump(dataMap, f)

You have a dictionary, and now you have to convert it to a Python object:

class Struct:
    def __init__(self, **entries): 
        self.__dict__.update(entries)

Then you can use:

>>> args = your YAML dictionary
>>> s = Struct(**args)
>>> s
<__main__.Struct instance at 0x01D6A738>
>>> s...

and follow "Convert Python dict to object".

For more information you can look at pyyaml.org and this.

Another solution is to use "ctrl+shift+F". You can change the search location to a local directory rather than a solution or project. This will just take the place of the desktop search and you'll still need to get the latest code, but it will allow you to remain within Visual Studio to do your searching.

For those having a hard time implementing the accepted answer (which requires org.apache.http.entity.mime.MultipartEntity) you may be using org.apache.httpcomponents 4.2.* In this case, you have to explicitly install httpmime dependency, in my case:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpmime</artifactId>
    <version>4.2.5</version>
</dependency>

When you write

df['Date'] = pd.to_datetime(df['Date'], errors='coerce')
df['Date'] = df['Date'].dt.strftime('%m/%d')

It can fixed

SELECT o.*, GROUP_CONCAT(c.name) FROM Orders AS o , Company.c
    WHERE FIND_IN_SET(c.CompanyID , o.attachedCompanyIDs) GROUP BY o.attachedCompanyIDs

Also if you want to do something like ClassB.Run("thing");, make sure the Method Run(); is static or you could call it like this: thing.Run("thing");.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Assuming that "a" and "b" are bean properties

rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"

You may look at JSF EL operators

You need to type result to an array of string const result: string[] = [];.

We can use LIMIT like bellow:

Model::take(20)->get();

Convert datatable to JSON using C#.net

 public static object DataTableToJSON(DataTable table)
    {
        var list = new List<Dictionary<string, object>>();

        foreach (DataRow row in table.Rows)
        {
            var dict = new Dictionary<string, object>();

            foreach (DataColumn col in table.Columns)
            {
                dict[col.ColumnName] = (Convert.ToString(row[col]));
            }
            list.Add(dict);
        }
        JavaScriptSerializer serializer = new JavaScriptSerializer();

        return serializer.Serialize(list);
    }

you can simply use this code:

ggplot(yourdatasetname, aes(Position, fill = Name)) + 
     geom_bar(col = "black", size = 2)

EDIT: It appears that this method is not supported anymore (thx to @FernandoZamperin). Please take a look at the other answers!

Instead of subscribing to a topic you could instead make use of the condition key and send messages to instances, that are not in a group. Your data might look something like this:

{
    "data": {
        "foo": "bar"
    },
    "condition": "!('anytopicyoudontwanttouse' in topics)"
}

See https://firebase.google.com/docs/cloud-messaging/send-message#send_messages_to_topics_2

You could set like this

button.setAllCaps(false);

programmatically

From java.util.Date to XMLGregorianCalendar you can simply do:

import javax.xml.datatype.XMLGregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import java.util.GregorianCalendar;
......
GregorianCalendar gcalendar = new GregorianCalendar();
gcalendar.setTime(yourDate);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(gcalendar);

Code edited after the first comment of @f-puras, by cause i do a mistake.

You can get selected option text by using function .text();

you can call the function like this :

jQuery("select option:selected").text();

Another way:

for %f in (*.mp4) do call ffmpeg -i "%~f" -vcodec copy -acodec copy "%~nf.avi"

I'm working on a Yocto Linux system that has a limited set of available Linux tools. I wanted to kill the process that was using a particular port (1883).

First, to see what ports we are listening to I used the following command:

root@root:~# netstat -lt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 0.0.0.0:hostmon         0.0.0.0:*               LISTEN      
tcp        0      0 localhost.localdomain:domain 0.0.0.0:*               LISTEN      
tcp        0      0 0.0.0.0:9080            0.0.0.0:*               LISTEN      
tcp        0      0 0.0.0.0:1883            0.0.0.0:*               LISTEN      
tcp        0      0 :::hostmon              :::*                    LISTEN      
tcp        0      0 localhost:domain        :::*                    LISTEN      
tcp        0      0 :::ssh                  :::*                    LISTEN      
tcp        0      0 :::1883                 :::*                    LISTEN      

Next, I found the name of the process using port 1883 in the following way:

root@root:~# fuser 1883/tcp
290 
root@root:~# ps | grep 290
  290 mosquitt 25508 S    /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
12141 root      8444 S    grep 290

As we can see above, it's the program /usr/sbin/mosquitto that's using port 1883.

Lastly, I killed the process:

root@root:~# systemctl stop mosquitto

I used systemctl becuase in this case it was a systemd service.

I think it will be easier using syntax-based query:

var entryPoint = (from ep in dbContext.tbl_EntryPoint
                 join e in dbContext.tbl_Entry on ep.EID equals e.EID
                 join t in dbContext.tbl_Title on e.TID equals t.TID
                 where e.OwnerID == user.UID
                 select new {
                     UID = e.OwnerID,
                     TID = e.TID,
                     Title = t.Title,
                     EID = e.EID
                 }).Take(10);

And you should probably add orderby clause, to make sure Top(10) returns correct top ten items.

def xstr(s):
   return s or ""

This is my version of a drop shadow. I was going for a hazy shadow all around the shape and used this answer by Joakim Lundborg as my starting point. What I changed is to add corners to all the shadow items and to increase the radius of the corner for each subsequent shadow item. So here is the xml:

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

            <corners android:radius="8dp" />
        </shape>

You need the n flag. To count words use:

:%s/\i\+/&/gn   

and a particular word:

:%s/the/&/gn        

See count-items documentation section.

If you simply type in:

%s/pattern/pattern/g

then the status line will give you the number of matches in vi as well.

You may try dbForge Data Compare for Oracle, a **free GUI tool for data comparison and synchronization, that can do these actions over all database or partially.

well this method is not a good one, but easy and not suggested. Maybe i should say this is the least effective method and the worse coding practice but, fun to use,

float val=10.0;
String str=val+"";

the empty quotes, add a null string to the variable str, upcasting 'val' to the string type.

TryParse works if your number is less than Int32.MaxValue. This also gives you the opportunity to handle badly formatted strings. Works the same for Int64.MaxValue and Int64.TryParse.

int number;
if(Int32.TryParse(nvarchar, out number))
{
   // etc...
   number.ToString();
}

You have a single quotes conflict, so use:

 echo "A,B,C" | sed "s/,/','/g"

If using bash, you can do too (<<< is a here-string):

sed "s/,/','/g" <<< "A,B,C"

but not

sed "s/,/','/g"  "A,B,C"

because sed expect file(s) as argument(s)

EDIT:

if you use ksh or any other ones :

echo string | sed ...

This worked for me

jQuery(document).ready(function(){ 
        jQuery('input').keyup(function() {
            this.value = this.value.toLocaleUpperCase();
        });
        jQuery('textarea').keyup(function() {
            this.value = this.value.toLocaleUpperCase();
        });
 });

Yup, often called a 'cookie jar' Google should provide many examples:

http://devzone.zend.com/16/php-101-part-10-a-session-in-the-cookie-jar/

http://curl.haxx.se/libcurl/php/examples/cookiejar.html <- good example IMHO

Copying that last one here so it does not go away...

Login to on one page and then get another page passing all cookies from the first page along Written by Mitchell

<?php
/*
This script is an example of using curl in php to log into on one page and 
then get another page passing all cookies from the first page along with you.
If this script was a bit more advanced it might trick the server into 
thinking its netscape and even pass a fake referer, yo look like it surfed 
from a local page.
*/

$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"http://www.myterminal.com/checkpwd.asp");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "UserID=username&password=passwd");

ob_start();      // prevent any output
curl_exec ($ch); // execute the curl command
ob_end_clean();  // stop preventing output

curl_close ($ch);

readdir() does that.

Check http://perldoc.perl.org/functions/readdir.html

opendir(DIR, $some_dir) || die "can't opendir $some_dir: $!";
@dots = grep { /^\./ && -f "$some_dir/$_" } readdir(DIR);
closedir DIR;

Validates such values as: "", "FIR", "FIR ", "FIR LAST"

/^[A-z]*$|^[A-z]+\s[A-z]*$/

If you don't want use external package , Just add the following function in your utilities :

var params=function(req){
  let q=req.url.split('?'),result={};
  if(q.length>=2){
      q[1].split('&').forEach((item)=>{
           try {
             result[item.split('=')[0]]=item.split('=')[1];
           } catch (e) {
             result[item.split('=')[0]]='';
           }
      })
  }
  return result;
}

Then , in createServer call back , add attribute params to request object :

 http.createServer(function(req,res){
     req.params=params(req); // call the function above ;
      /**
       * http://mysite/add?name=Ahmed
       */
     console.log(req.params.name) ; // display : "Ahmed"

})

This can also occur if the read end of the output from your script dies prematurely

ie open.py | otherCommand

if otherCommand exits and open.py tries to write to stdout

I had a bad gawk script that did this lovely to me.

I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.
