Several answers here use range. xrange is generally better as it returns a generator, rather than a fully-instantiated list. Where memory and or iterables of widely-varying lengths can be an issue, xrange is superior.

This is a very old question, but unfortunately this issue is still relevant and requires a solution.

The (suprisingly simple) solution I've come up with is to "hide" the actual file input field and wrap it with a LABEL tag (can be based on Bootstrap and HTML5, for enhancement).

See here:Example code here

This way, the real file input field is invisible and all you see is the customized "button" which is actually a modified LABEL element. When you click on this LABEL element, the window for selecting a file comes up and the file you choose will go into the real file input field.

On top of that, you can manipulate the look and behaviour as you wish (for example: get the name of the selected file from the file input file, after selected, and show it somewhere. The LABEL element doesn't do that automatically, of course. I usually just put it inside the LABEL, as its text content).

Beware though! The manipulation of the look and behaviour of this is limited to whatever you can imagine and think of.    ;-)  ;-)

You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.

Let's say you're making some kind of dashboard widget. As part of this, you want it to display the unread message count in your email box. So you make a little thread that will:

1. Connect to the mail server and ask how many unread messages you have.
2. Signal the GUI with the updated count.
3. Sleep for a little while.

When your widget starts up, it would create this thread, designate it a daemon, and start it. Because it's a daemon, you don't have to think about it; when your widget exits, the thread will stop automatically.

It actually depends on what is being used to print the result. Usually, the result is the same, just as you say -

Historically carriage return is supposed to do about what the home button does: return the caret to the start of the line.

\n is supposed to give you a new line but not move the caret.

If you think about old printers, you're pretty much thinking how the original authors of the character sets were thinking. It's a different operation moving the paper feeder and moving the caret. These two characters express that difference.

I had the same:

Error opening registry key 'Software\JavaSoft\Java Runtime Environment

Clearing Windows\SysWOW64 doesn't help for Win7

In my case it installing JDK8 offline helped (from link)

When indicating HTTP Basic Authentication we return something like:

WWW-Authenticate: Basic realm="myRealm"

Whereas Basic is the scheme and the remainder is very much dependent on that scheme. In this case realm just provides the browser a literal that can be displayed to the user when prompting for the user id and password.

You're obviously not using Basic however since there is no point having session expiry when Basic Auth is used. I assume you're using some form of Forms based authentication.

From recollection, Windows Challenge Response uses a different scheme and different arguments.

The trick is that it's up to the browser to determine what schemes it supports and how it responds to them.

My gut feel if you are using forms based authentication is to stay with the 200 + relogin page but add a custom header that the browser will ignore but your AJAX can identify.

For a really good User + AJAX experience, get the script to hang on to the AJAX request that found the session expired, fire off a relogin request via a popup, and on success, resubmit the original AJAX request and carry on as normal.

Avoid the cheat that just gets the script to hit the site every 5 mins to keep the session alive cause that just defeats the point of session expiry.

The other alternative is burn the AJAX request but that's a poor user experience.

Have you considered lsof (list open files)?

A simple way of binding a variable to an input (two-way binding) is to just directly access the input element in the getter and setter:

var variable = function(element){                    
                   return {
                       get : function () { return element.value;},
                       set : function (value) { element.value = value;} 
                   }
               };

In HTML:

<input id="an-input" />
<input id="another-input" />

And to use:

var myVar = new variable(document.getElementById("an-input"));
myVar.set(10);

// and another example:
var myVar2 = new variable(document.getElementById("another-input"));
myVar.set(myVar2.get());

var variable = function(element){

                return function () {
                    if(arguments.length > 0)                        
                        element.value = arguments[0];                                           

                    else return element.value;                                                  
                }

        }

To use:

var v1 = new variable(document.getElementById("an-input"));
v1(10); // sets value to 20.
console.log(v1()); // reads value.

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

From "Fixing LINQ Error: Sequence contains no elements":

When you get the LINQ error "Sequence contains no elements", this is usually because you are using the First() or Single() command rather than FirstOrDefault() and SingleOrDefault().

This can also be caused by the following commands:

• FirstAsync()
• SingleAsync()
• Last()
• LastAsync()
• Max()
• Min()
• Average()
• Aggregate()

The parameters to main represent the command line parameters provided to the program when it was started. The argc parameter represents the number of command line arguments, and char *argv[] is an array of strings (character pointers) representing the individual arguments provided on the command line.

IrishChieftain didn't really address the question, so here's my take:

eval() is supposed to be used for data that is not known at run time. Whether that be user input (dangerous) or other sources.

In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.

Abstract:

The reason why you are getting this error message is because you are trying to call a method on an int type of a variable. This would work if would have called len() function on a list type of a variable. Let's examin the two cases:

Fail:

num = 10

print(len(num))

The above will produce an error similar to yours due to calling len() function on an int type of a variable;

Success:

data = [0, 4, 8, 9, 12]

print(len(data))

The above will work since you are calling a function on a list type of a variable;

public static class GlobalVariables
{
    // readonly variable
    public static string Foo
    {
        get
        {
            return "foo";
        }
    }

    // read-write variable
    public static string Bar
    {
        get
        {
            return HttpContext.Current.Application["Bar"] as string;
        }
        set
        {
            HttpContext.Current.Application["Bar"] = value;
        }
    }
}

To include png and jpg, you need to specify the Bounding Box explicitly.

\includegraphics[bb=0 0 1280 960]{images/some_image.png}

Where 1280 and 960 are respectively width and height.

You will need to read the bytes from that File into a byte[] and put that object into your JSONObject.

You should also have a look at the following posts :

• ByteArray in JSON
• Binary Data in JSON String. Something better than Base64
• BSON library for java

Hope this helps.

File Path Seems to be an issue here please make sure that file exists in the correct directory or give the absolute path to make sure that you are pointing to a correct file. Please log the file.getAbsolutePath() to verify that file is correct.

The problem is with your line

x=np.array ([x0*n])

Here you define x as a single-item array of -200.0. You could do this:

x=np.array ([x0,]*n)

or this:

x=np.zeros((n,)) + x0

Note: your imports are quite confused. You import numpy modules three times in the header, and then later import pylab (that already contains all numpy modules). If you want to go easy, with one single

from pylab import *

line in the top you could use all the modules you need.

This is a convention defined in RFC 2045 - Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies.

1. Private [subtype] values (starting with "X-") may be defined bilaterally between two cooperating agents without outside registration or standardization. Such values cannot be registered or standardized.

2. New standard values should be registered with IANA as described in RFC 2048.

A similar restriction applies to the top-level type. From the same source,

If another top-level type is to be used for any reason, it must be given a name starting with "X-" to indicate its non-standard status and to avoid a potential conflict with a future official name.

(Note that per RFC 2045, "[m]atching of media type and subtype is ALWAYS case-insensitive", so there's no difference between the interpretation of 'X-' and 'x-'.)

So it's fair to guess that "application/x-foo" was used before the IANA defined "application/foo". And it still might be used by folks who aren't aware of the IANA token assignment.

As Chris Hanson said MIME types are controlled by the IANA. This is detailed in RFC 2048 - Multipurpose Internet Mail Extensions (MIME) Part Four: Registration Procedures. According to RFC 3778, which is cited by the IANA as the definition for "application/pdf",

The application/pdf media type was first registered in 1993 by Paul Lindner for use by the gopher protocol; the registration was subsequently updated in 1994 by Steve Zilles.

The type "application/pdf" has been around for well over a decade. So it seems to me that wherever "application/x-pdf" has been used in new apps, the decision may not have been deliberate.

I use something like this to load properties file.

        final ResourceBundle bundle = ResourceBundle
                .getBundle("properties/errormessages");

        for (final Enumeration<String> keys = bundle.getKeys(); keys
                .hasMoreElements();) {
            final String key = keys.nextElement();
            final String value = bundle.getString(key);
            prop.put(key, value);
        }

There is also some more detail on the use of <mvc:annotation-driven /> in the Spring docs. In a nutshell, <mvc:annotation-driven /> gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.

Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven /> enables the use of the @Transaction annotation, <task:annotation-driven /> is required for @Scheduled et al...

If you are working in Visual studio. You can try this fix

1. Unload your project from visual studio
2. Go to your project home directory and Open "csproj" file.

3. Add TypeScriptExperimentalDecorators to this section as shown in image

   

   4. Reload the project in Visual studio.

The get method of the HashMap is returning an Object, but the variable current is expected to take a ArrayList:

ArrayList current = new ArrayList();
// ...
current = dictMap.get(dictCode);

For the above code to work, the Object must be cast to an ArrayList:

ArrayList current = new ArrayList();
// ...
current = (ArrayList)dictMap.get(dictCode);

However, probably the better way would be to use generic collection objects in the first place:

HashMap<String, ArrayList<Object>> dictMap =
    new HashMap<String, ArrayList<Object>>();

// Populate the HashMap.

ArrayList<Object> current = new ArrayList<Object>();      
if(dictMap.containsKey(dictCode)) {
    current = dictMap.get(dictCode);   
}

The above code is assuming that the ArrayList has a list of Objects, and that should be changed as necessary.

For more information on generics, The Java Tutorials has a lesson on generics.

I'm not really sure what 'tag' is, but branch is a fairly common source control concept.

Basically, a branch is a way to work on changes to the code without affecting trunk. Say you want to add a new feature that's fairly complicated. You want to be able to check in changes as you make them, but don't want it to affect trunk until you're done with the feature.

First you'd create a branch. This is basically a copy of trunk as-of the time you made the branch. You'd then do all your work in the branch. Any changes made in the branch don't affect trunk, so trunk is still usable, allowing others to continue working there (like doing bugfixes or small enhancements). Once your feature is done you'd integrate the branch back into trunk. This would move all your changes from the branch to trunk.

There are a number of patterns people use for branches. If you have a product with multiple major versions being supported at once, usually each version would be a branch. Where I work we have a QA branch and a Production branch. Before releasing our code to QA we integrate changes to the QA branch, then deploy from there. When releasing to production we integrate from the QA branch to the Production branch, so we know the code running in production is identical to what QA tested.

Here's the Wikipedia entry on branches, since they probably explain things better than I can. :)

For me none of above worked. However, I solved problem with installing libssl-dev.

sudo apt-get install libssl-dev

This might work if you have same error message as in my case:

fatal error: openssl/opensslv.h: No such file or directory ... .... command 'x86_64-linux-gnu-gcc' failed with exit status 1

You should be strongly typing your views. Then you can do this:

public class YourViewModel {
    public bool ConditionaValue { get; set; }
}

In your view, you can create a checkbox that will bind to this boolean value:

@Html.CheckBoxFor(x => x.ConditionalValue)

If it is checked, the model property will be true.

For your immediate problem though.. you need to name your checkbox to be the same name as your action method parameters.. and they should be bool..

Try:

div{_x000D_
-webkit-box-shadow:0px 1px 1px #de1dde;_x000D_
 -moz-box-shadow:0px 1px 1px #de1dde;_x000D_
 box-shadow:0px 1px 1px #de1dde;_x000D_
  }

<div>wefwefwef</div>

It generally adds a 1px blurred shadow 1px from the bottom of the box

box-shadow: [horizontal offset] [vertical offset] [blur radius] [color];

One of the simplest way is to use flatten(), like this example :

 import numpy as np

 batch_y =train_output.iloc[sample, :]
 batch_y = np.array(batch_y).flatten()

My array it was like this :

    0
0   6
1   6
2   5
3   4
4   3
.
.
.

After using flatten():

array([6, 6, 5, ..., 5, 3, 6])

It's also the solution of errors of this type :

Cannot feed value of shape (100, 1) for Tensor 'input/Y:0', which has shape '(?,)' 

To compare strings with wildcards use

if [[ "$stringA" == *$stringB* ]]; then
  # Do something here
else
  # Do Something here
fi

Python has more than one way to do strings. The following string syntax would allow you to use double quotes:

'''what"ever'''

As of git version 2.13, git supports conditional configuration includes. In this example we clone Company A's repos in ~/company_a directory, and Company B's repos in ~/company_b.

In your .gitconfig you can put something like this.

[includeIf "gitdir:~/company_a/"]
  path = .gitconfig-company_a
[includeIf "gitdir:~/company_b/"]
  path = .gitconfig-company_b

Example contents of .gitconfig-company_a

[user]
name = John Smith
email = [email protected]

Example contents of .gitconfig-company_b

[user]
name = John Smith
email = [email protected]

The free version of TightVnc viewer (I have TightVnc Viewer 1.5.4 8/3/2011) build does not support this. What you need is RealVNC but VNC Enterprise Edition 4.2 or the Personal Edition. Unfortunately this is not free and you have to pay for a license.

From the RealVNC website [releasenote] http://www.realvnc.com/products/enterprise/4.2/release-notes.html

VNC Viewer: Full-screen mode can span monitors on a multi-monitor system.

In many environments (e.g. Heroku), and as a convention, you can set the environment variable PORT to tell your web server what port to listen on.

So process.env.PORT || 3000 means: whatever is in the environment variable PORT, or 3000 if there's nothing there.

So you pass that to app.listen, or to app.set('port', ...), and that makes your server able to accept a "what port to listen on" parameter from the environment.

If you pass 3000 hard-coded to app.listen(), you're always listening on port 3000, which might be just for you, or not, depending on your requirements and the requirements of the environment in which you're running your server.

Some practical uses for the [Serializable] attribute:

• Saving object state using binary serialisation; you can very easily 'save' entire object instances in your application to a file or network stream and then recreate them by deserialising - check out the BinaryFormatter class in System.Runtime.Serialization.Formatters.Binary
• Writing classes whose object instances can be stored on the clipboard using Clipboard.SetData() - nonserialisable classes cannot be placed on the clipboard.
• Writing classes which are compatible with .NET Remoting; generally, any class instance you pass between application domains (except those which extend from MarshalByRefObject) must be serialisable.

These are the most common usage cases that I have come across.

If you are having this problem for a React Native app, in addition to above mentioned steps, make sure you have the local.properties file in the android directory(AppName/android) of your app which points to your 'sdk' directory:

sdk.dir=/PATH_TO_SDK/

In SSMS, you can't print new line with select, just using PRINT instead

DECLARE @text NVARCHAR(100)
SET @text = concat(N'This is line 1.', CHAR(10), N'This is line 2.')
PRINT @text

If you look in the ISAPI And CGI Restrictions, and everything is already set to Allowed, then make sure that the ASP.NET v4.0.30319 handlers are even in the list. In my case they were not. This can be easy to overlook.

I added one for 32 %windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll and another for 64 bit %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll. You can name them both the same ASP.NET v4.0.30319.

If the iframe was not on a different domain, you could do something like this:

document.getElementById(FrameID).contentDocument.location.reload(true);

But since the iframe is on a different domain, you will be denied access to the iframe's contentDocument property by the same-origin policy.

But you can hackishly force the cross-domain iframe to reload if your code is running on the iframe's parent page, by setting it's src attribute to itself. Like this:

// hackishly force iframe to reload
var iframe = document.getElementById(FrameId);
iframe.src = iframe.src;

If you are trying to reload the iframe from another iframe, you are out of luck, that is not possible.

This is an addendum to the accepted answer by AndreyT, with Nyan's comment on mismatched array sizes. I disagree with their automatic setting of the fifth element to zero. It should likely be 5 --the number after 1,2,3,4. So I would suggest a wrapper to memcpy() to produce a compile-time error when we try to copy arrays of different sizes:

#define Memcpy(a,b) do {                    /* copy arrays */       \
    ASSERT(sizeof(a) == sizeof(b) &&        /* a static assert */   \
           sizeof(a) != sizeof((a) + 0));   /* no pointers */       \
    memcpy((a), (b), sizeof (b));           /* & unnecesary */      \
    } while (0)                             /* no return value */

This macro will generate a compile-time error if your array is of length 1. Which is perhaps a feature.

Because we are using a macro, the C99 compound literal seems to need an extra pair of parentheses:

Memcpy(myarray, ((int[]) { 1, 2, 3, 4 }));

Here ASSERT() is a 'static assert'. If you don't already have your own, I use the following on a number of platforms:

#define CONCAT_TOKENS(a, b) a ## b
#define EXPAND_THEN_CONCAT(a,b) CONCAT_TOKENS(a, b)
#define ASSERT(e) enum {EXPAND_THEN_CONCAT(ASSERT_line_,__LINE__) = 1/!!(e)}
#define ASSERTM(e,m) /* version of ASSERT() with message */ \
    enum{EXPAND_THEN_CONCAT(m##_ASSERT_line_,__LINE__)=1/!!(e)}

I don't think you can use braces.

According to the Bash manual about case in Conditional Constructs.

Each pattern undergoes tilde expansion, parameter expansion, command substitution, and arithmetic expansion.

Nothing about Brace Expansion unfortunately.

So you'd have to do something like this:

case $1 in
    req*)
        ...
        ;;
    met*|meet*)
        ...
        ;;
    *)
        # You should have a default one too.

To read a particular date from range EJ_PAYDATES_2021 (index is next to the last "1")

=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,1,1)  // Jan
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,2,1)  // Feb
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,3,1)  // Mar

This allows reading a particular element of a range [0] etc from another spreadsheet file. Target file need not be open. Range in the above example is named EJ_PAYDATES_2021, with one element for each month contained within that range.

Took me a while to parse this out, but it works, and is the answer to the question asked above.

Just posted my finished code for a similar project. It copies files of certain extensions in my code its pdf tif and tiff you can change them to whatever you want copied or delete the if statements if you only need 1 or 2 types. When a file is created or modified it gets the archive attribute this code also looks for that attribute and only copies it if it exists and then removes it after its copied so you dont copy unneeded files. It also has a log setup in it so that you will see a log of what time and day evetrything was transfered from the last time you ran the script.

I got openCV installed smoothly in my mac by:

$ brew link --overwrite --dry-run opencv // to force linking
$ pip3 install opencv-contrib-python

I got it at windows 10 using:

c:\> pip3 install opencv-python
c:\> pip3 install opencv-contrib-python

Then I got it tested by

$ python3

About the server can deliver to the clients the root cert or not, extracted from the RFC-5246 'The Transport Layer Security (TLS) Protocol Version 1.2' doc it says:

certificate_list
This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the
assumption that the remote end must already possess it in order to validate it in any case.

About the term 'MAY', extracted from the RFC-2119 "Best Current Practice" says:

5.MAY
This word, or the adjective "OPTIONAL", mean that an item is truly optional. One vendor may choose to include the item because a
particular marketplace requires it or because the vendor feels that
it enhances the product while another vendor may omit the same item.
An implementation which does not include a particular option MUST be
prepared to interoperate with another implementation which does
include the option, though perhaps with reduced functionality. In the same vein an implementation which does include a particular option
MUST be prepared to interoperate with another implementation which
does not include the option (except, of course, for the feature the
option provides.)

In conclusion, the root may be at the certification path delivered by the server in the handshake.

A practical use.
Think about, not in navigator user terms, but on a transfer tool at a server in a militarized zone with limited internet access.
The server, playing the client role at the transfer, receives all the certs path from the server.
All the certs in the chain should be checked to be trusted, root included.
The only way to check this is the root be included at the certs path in transfer time, being matched against a previously declared as 'trusted' local copy of them.

You should bear in mind that a-z, A-Z, 0-9, ., _ and - are not the only valid characters in the start of an email address.

Gmail, for example, lets you put a "+" sign in the address to "fake" a different email (e.g. [email protected] will also get email sent to [email protected]).

micky.o'[email protected] would not appreciate your code stopping them entering their address ... apostrophes are perfectly valid in email addresses.

The Closure "check" of a valid email address mentioned above is, as it states itself, quite naïve:

http://code.google.com/p/closure-library/source/browse/trunk/closure/goog/format/emailaddress.js#198

I recommend being very open in your client side code, and then much more heavyweight like sending an email with a link to really check that it's "valid" (as in - syntactically valid for their provider, and also not misspelled).

Something like this:

var pattern = /[^@]+@[-a-z\.]\.[a-z\.]{2,6}/

Bearing in mind that theoretically you can have two @ signs in an email address, and I haven't even included characters beyond latin1 in the domain names!

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

Inversion of Control, (or IoC), is about getting freedom (You get married, you lost freedom and you are being controlled. You divorced, you have just implemented Inversion of Control. That's what we called, "decoupled". Good computer system discourages some very close relationship.) more flexibility (The kitchen in your office only serves clean tap water, that is your only choice when you want to drink. Your boss implemented Inversion of Control by setting up a new coffee machine. Now you get the flexibility of choosing either tap water or coffee.) and less dependency (Your partner has a job, you don't have a job, you financially depend on your partner, so you are controlled. You find a job, you have implemented Inversion of Control. Good computer system encourages in-dependency.)

When you use a desktop computer, you have slaved (or say, controlled). You have to sit before a screen and look at it. Using the keyboard to type and using the mouse to navigate. And a badly written software can slave you even more. If you replace your desktop with a laptop, then you somewhat inverted control. You can easily take it and move around. So now you can control where you are with your computer, instead of your computer controlling it.

By implementing Inversion of Control, a software/object consumer gets more controls/options over the software/objects, instead of being controlled or having fewer options.

With the above ideas in mind. We still miss a key part of IoC. In the scenario of IoC, the software/object consumer is a sophisticated framework. That means the code you created is not called by yourself. Now let's explain why this way works better for a web application.

Suppose your code is a group of workers. They need to build a car. These workers need a place and tools (a software framework) to build the car. A traditional software framework will be like a garage with many tools. So the workers need to make a plan themselves and use the tools to build the car. Building a car is not an easy business, it will be really hard for the workers to plan and cooperate properly. A modern software framework will be like a modern car factory with all the facilities and managers in place. The workers do not have to make any plan, the managers (part of the framework, they are the smartest people and made the most sophisticated plan) will help coordinate so that the workers know when to do their job (framework calls your code). The workers just need to be flexible enough to use any tools the managers give to them (by using Dependency Injection).

Although the workers give the control of managing the project on the top level to the managers (the framework). But it is good to have some professionals help out. This is the concept of IoC truly come from.

Modern Web applications with an MVC architecture depends on the framework to do URL Routing and put Controllers in place for the framework to call.

Dependency Injection and Inversion of Control are related. Dependency Injection is at the micro level and Inversion of Control is at the macro level. You have to eat every bite (implement DI) in order to finish a meal (implement IoC).

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

Install pip

Download get-pip. Remember to save it as "get-pip.py"

Now go to the download folder. Right click on get-pip.py then open with python.exe.

You can add system variable by

(by doing this you can use pip and easy_install without specifying path)

1 Clicking on Properties of My Computer

2 Then chose Advanced System Settings

3 Click on Advanced Tab

4 Click on Environment Variables

5 From System Variables >>> select variable path.

6 Click edit then add the following lines at the end of it

 ;c:\Python27;c:\Python27\Scripts

(please dont copy this, just go to your python directory and copy the paths similar to this)

NB:- you have to do this once only.

Install beautifulsoup4

Open cmd and type

pip install beautifulsoup4

The verbose option is handy, but if you want to see everything that curl does (including the HTTP body that is transmitted, and not just the headers), I suggest using one of the below options:

• --trace-ascii - # stdout
• --trace-ascii output_file.txt # file

This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...

It seems a lot of different libraries and what not have seem to come and go over the previous years. However as of April 2016, this solution worked well for me. Strings easily replaced by ints.

TL/DR; Copy this if that's what you came here for:

    //outputfilename will be something like: "C:/MyFolder/MyFile.txt"
    void WriteDictionaryAsJson(Dictionary<string, List<string>> myDict, string outputfilename)
    {
        DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(Dictionary<string, List<string>>));
        MemoryStream ms = new MemoryStream();
        js.WriteObject(ms, myDict); //Does the serialization.

        StreamWriter streamwriter = new StreamWriter(outputfilename);
        streamwriter.AutoFlush = true; // Without this, I've run into issues with the stream being "full"...this solves that problem.

        ms.Position = 0; //ms contains our data in json format, so let's start from the beginning
        StreamReader sr = new StreamReader(ms); //Read all of our memory
        streamwriter.WriteLine(sr.ReadToEnd()); // and write it out.

        ms.Close(); //Shutdown everything since we're done.
        streamwriter.Close();
        sr.Close();
    }

Two import points. First, be sure to add System.Runtime.Serliazation as a reference in your project inside Visual Studio's Solution Explorer. Second, add this line,

using System.Runtime.Serialization.Json;

at the top of the file with the rest of your usings, so the DataContractJsonSerializer class can be found. This blog post has more information on this method of serialization.

Data Format (Input / Output)

My data is a dictionary with 3 strings, each pointing to a list of strings. The lists of strings have lengths 3, 4, and 1. The data looks like this:

StringKeyofDictionary1 => ["abc","def","ghi"]
StringKeyofDictionary2 => ["String01","String02","String03","String04"]
Stringkey3 => ["someString"]

The output written to file will be on one line, here is the formatted output:

 [{
     "Key": "StringKeyofDictionary1",
     "Value": ["abc",
     "def",
     "ghi"]
 },
 {
     "Key": "StringKeyofDictionary2",
     "Value": ["String01",
     "String02",
     "String03",
     "String04",
 ]
 },
 {
     "Key": "Stringkey3",
     "Value": ["SomeString"]
 }]

This is based off of "default locale"'s answer but it will remove invalid column names prior to setting ordinal. This is because if you accidentally send an invalid column name then it would fail and if you put a check to prevent it from failing then the index would be wrong since it would skip indices wherever an invalid column name was passed in.

public static class DataTableExtensions
{
    /// <summary>
    /// SetOrdinal of DataTable columns based on the index of the columnNames array. Removes invalid column names first.
    /// </summary>
    /// <param name="table"></param>
    /// <param name="columnNames"></param>
    /// <remarks> http://stackoverflow.com/questions/3757997/how-to-change-datatable-colums-order</remarks>
    public static void SetColumnsOrder(this DataTable dtbl, params String[] columnNames)
    {
        List<string> listColNames = columnNames.ToList();

        //Remove invalid column names.
        foreach (string colName in columnNames)
        {
            if (!dtbl.Columns.Contains(colName))
            {
                listColNames.Remove(colName);
            }
        }

        foreach (string colName in listColNames)
        {
            dtbl.Columns[colName].SetOrdinal(listColNames.IndexOf(colName));
        }
}

If you want folding an all your editors, I found you can enable Folding in

Preferences > Editors > Structured Text Editors

Enable Folding

To make everything writable by the owner, read/execute by the group, and world executable:

chmod -R 0755

To make everything wide open:

chmod -R 0777

The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:

CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X  int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

I just want to add some remarks to the great answer by Fredrik.

The Java Language Specification in Section 4.3.1 states

An object is a class instance or an array.

So array has indeed a very special role in Java. I do wonder why.

One could argue that current implementation array is/was important for a better performance. But than it is an internal structure, which should not be exposed.

They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

I agree with Fredrik, that a smart compiler optimazation would have been the better choice. This would also solve the problem, that even if you use a property for arrays, you have not solved the problem for strings and other (immutable) collection types, because, e.g., string is based on a char array as you can see on the class definition of String:

public final class String implements java.io.Serializable, Comparable<String>, CharSequence {           
    private final char value[]; // ...

And I do not agree with that it would be even more confusing, because array does inherit all methods from java.lang.Object.

As an engineer I really do not like the answer "Because it has been always this way." and wished there would be a better answer. But in this case it seems to be.

tl;dr

In my opinion, it is a design flaw of Java and should not have implemented this way.

"Core Java" is Sun's term, used to refer to Java SE, the standard edition and a set of related technologies, like the Java VM, CORBA, et cetera. This is mostly to differentiate from, say, Java ME or Java EE.

Also note that they're talking about a set of libraries rather than the programming language. That is, the underlying way you write Java doesn't change, regardless of the libraries you're using.

Use std::bitset

#include <bitset>
#include <iostream>

int main()
{
    int temp = 0x5E;
    std::bitset<sizeof(int)*CHAR_BITS>   bits(temp);

    // 0 -> bit 1
    // 2 -> bit 3
    std::cout << bits[2] << std::endl;
}

What you need are character classes. In that, you've only to worry about the ], \ and - characters (and ^ if you're placing it straight after the beginning of the character class "[" ).

Syntax: [characters] where characters is a list with characters.

Example:

var cleanString = dirtyString.replace(/[|&;$%@"<>()+,]/g, "");

The best one by far is

bool(re.search('ba[rzd]', 'foobarrrr'))

Returns True

I am a beginner myself and I honestly couldn't find a satisfactory answer that I could understand or implement.

So here's an external link that I really helped me achieved what I wanted. It's very straight forward and easy to follow as well.

http://www.helloandroid.com/tutorials/how-display-custom-dialog-your-android-application

THIS WHAT I TRIED TO ACHIEVE WITH THE CODE:

I have a MainActivity that hosts a Fragment. I wanted a dialog to appear on top of the layout to ask for user input and then process the input accordingly. See a screenshot

Here's what the onCreateView of my fragment looks

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_home_activity, container, false);

    Button addTransactionBtn = rootView.findViewById(R.id.addTransactionBtn);

    addTransactionBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Dialog dialog = new Dialog(getActivity());
            dialog.setContentView(R.layout.dialog_trans);
            dialog.setTitle("Add an Expense");
            dialog.setCancelable(true);

            dialog.show();

        }
    });

I hope it will help you

Let me know if there's any confusion. :)

One options will be to show the selected option above (or below) the select list like following:

HTML

<div id="selText"><span>&nbsp;</span></div><br/>
<select size="4" id="mySelect" style="width:65px;color:#f98ad3;">
    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>

JavaScript

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"   
  type="text/javascript"></script> 
<script type="text/javascript">
$(document).ready(function(){        
    $("select#mySelect").change(function(){
      //$("#selText").html($($(this).children("option:selected")[0]).text());
       var txt = $($(this).children("option:selected")[0]).text();
       $("<span>" + txt + "<br/></span>").appendTo($("#selText span:last"));
    });
});
</script>

PS:- Set height of div#selText otherwise it will keep shifting select list downward.

You can delete a specific query parameter by using:

delete $location.$$search.nameOfParameter;

Or you can clear all the query params by setting search to an empty object:

$location.$$search = {};

I resolve similar problem with:

document.getElementById("xyz").style.padding = "10px 0 0 0";

Hope that helps.

You don't really need to have parenthesis. You can sort directly:

SELECT *, 1 AS RN FROM TABLE_A
UNION ALL 
SELECT *, 2 AS RN FROM TABLE_B
ORDER BY RN, COLUMN_1

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
    xmlDoc.async = false;_x000D_
    xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Postal Code_x000D_
console.log(xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue);

For example,

package main

import "fmt"

func CToGoString(c []byte) string {
    n := -1
    for i, b := range c {
        if b == 0 {
            break
        }
        n = i
    }
    return string(c[:n+1])
}

func main() {
    c := [100]byte{'a', 'b', 'c'}
    fmt.Println("C: ", len(c), c[:4])
    g := CToGoString(c[:])
    fmt.Println("Go:", len(g), g)
}

Output:

C:  100 [97 98 99 0]
Go: 3 abc

There are two obvious issues with the set literal syntax:

my_set = {'foo', 'bar', 'baz'}

1. It's not available before Python 2.7

2. There's no way to express an empty set using that syntax (using {} creates an empty dict)

Those may or may not be important to you.

The section of the docs outlining this syntax is here.

you can use more_itertools package.

import more_itertools

lst = range(1, 7)
for i, j in more_itertools.chunked(lst, 2):
    print(f'{i} + {j} = {i+j}')

I have an operation of transposition of bits that needs to be done, on 192 or 256 bits every interrupt, that happens every 50 microseconds.

It happens by a fixed map(hardware constraints). Using C, it took around 10 microseconds to make. When I translated this to Assembler, taking into account the specific features of this map, specific register caching, and using bit oriented operations; it took less than 3.5 microsecond to perform.

To go directly to that folder, you can use the Set-Location cmdlet or cd alias:

Set-Location "Q:\My Test Folder"

The Jenkinsfile is written in groovy which uses the Java (and C) form of comments:

/* this
   is a
   multi-line comment */

// this is a single line comment

Here's your bulletproof solution:

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
    <td width="35%" align="center" valign="top">
      CONTENT GOES HERE
    </td>
    <td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
  </tr>
</table>

Just Try it out, Looks a bit messy, but It works Even with the new Firefox Update for Yahoo mail. (doesn't center the email because replace the main table by a div)

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

Another thing on linux is:

send does not allow to operate on non-socket fd. Thus, for example to write on usb port, write is necessary.

Have a look at this one. It is the Ternary operator in C#.

bool BooleanValue = (num % 3 != 0) ? true : false;

This is just to show the principle; you can return True or False (or even integer or string) depending on the outcome of something on the left side of the question mark. Nice operator, this.

Three alternatives together:

      public bool test1()
        {
            int num = 21;
            bool BooleanValue = (num % 3 != 0) ? true : false;
            return BooleanValue;
        }

        public bool test2()
        {
            int num = 20;
            bool test = (num % 3 != 0);
            return test;
        }

Even Shorter:

public bool test3()
{
    int num = 20;
    return (bool)(num % 3 != 0);
}

(function() { var d = new Date(); return new Date(d - d % 86400000); })()

Converting from HTML to text using a DOMDocument is a viable solution. Consider HTML2Text, which requires PHP5:

• http://www.howtocreate.co.uk/php/html2texthowto.html
• http://www.howtocreate.co.uk/php/
• http://www.howtocreate.co.uk/jslibs/termsOfUse.html

Regarding UTF-8, the write-up on the "howto" page states:

PHP's own support for unicode is quite poor, and it does not always handle utf-8 correctly. Although the html2text script uses unicode-safe methods (without needing the mbstring module), it cannot always cope with PHP's own handling of encodings. PHP does not really understand unicode or encodings like utf-8, and uses the base encoding of the system, which tends to be one of the ISO-8859 family. As a result, what may look to you like a valid character in your text editor, in either utf-8 or single-byte, may well be misinterpreted by PHP. So even though you think you are feeding a valid character into html2text, you may well not be.

The author provides several approaches to solving this and states that version 2 of HTML2Text (using DOMDocument) has UTF-8 support.

Note the restrictions for commercial use.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

In Win 7, navigate to the directory where your text files are. On the command prompt use:

copy *.txt combined.txt

Where combined.txt is the name of the newly created text file.

Given that it is a dictionary you access it by using the keys. Getting the dictionary stored under "Apple", do the following:

>>> mydict["Apple"]
{'American': '16', 'Mexican': 10, 'Chinese': 5}

And getting how many of them are American (16), do like this:

>>> mydict["Apple"]["American"]
'16'

Platform-independent way (starting from c++11) is:

#include <thread>

std::this_thread::get_id();

If you want the GUI to behave as if you clicked the X close button then you need to dispatch a window closing event to the Window. The ExitAction from Closing An Application allows you to add this functionality to a menu item or any component that uses Actions easily.

frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));

I see that a few important reasons for doing as few new's as possible are missed:

Operator new has a non-deterministic execution time

Calling new may or may not cause the OS to allocate a new physical page to your process this can be quite slow if you do it often. Or it may already have a suitable memory location ready, we don't know. If your program needs to have consistent and predictable execution time (like in a real-time system or game/physics simulation) you need to avoid new in your time critical loops.

Operator new is an implicit thread synchronization

Yes you heard me, your OS needs to make sure your page tables are consistent and as such calling new will cause your thread to acquire an implicit mutex lock. If you are consistently calling new from many threads you are actually serialising your threads (I've done this with 32 CPUs, each hitting on new to get a few hundred bytes each, ouch! that was a royal p.i.t.a. to debug)

The rest such as slow, fragmentation, error prone, etc have already been mentioned by other answers.

yes, it was introduced in 1993.

FYI, it looks like the syntax for retrieving the values has changed according to:

http://freemarker.sourceforge.net/docs/ref_builtins_hash.html

<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

return RedirectToAction("ProductImageManager","Index", new   { id=id   });

Here is an invalid parameters order, should be an action first

I know this is a late entry but even in 2016 I am surprised by the complete lack of IE support for flex (currently 11 is the only one to support it and its majorly buggy at that http://caniuse.com/#feat=flexbox) which from a business perspective is not great! So I think until IE is shut down the best solution and most cross-browser friendly one surely must be a JS/Jquery one?

Most sites already use Jquery and a very simple example (for my code) is:

$('#auto_height_item').height($(window).height() - $('#header').height());

You can obviously replace window and header and let the basic math do the work. Personally I'm still not convinced about flex yet...

Erland Sommarskog has maintained the authoritative answer to this question for the last 16 years: Arrays and Lists in SQL Server.

There are at least a dozen ways to pass an array or list to a query; each has their own unique pros and cons.

• Table-Valued Parameters. SQL Server 2008 and higher only, and probably the closest to a universal "best" approach.
• The Iterative Method. Pass a delimited string and loop through it.
• Using the CLR. SQL Server 2005 and higher from .NET languages only.
• XML. Very good for inserting many rows; may be overkill for SELECTs.
• Table of Numbers. Higher performance/complexity than simple iterative method.
• Fixed-length Elements. Fixed length improves speed over the delimited string
• Function of Numbers. Variations of Table of Numbers and fixed-length where the number are generated in a function rather than taken from a table.
• Recursive Common Table Expression (CTE). SQL Server 2005 and higher, still not too complex and higher performance than iterative method.
• Dynamic SQL. Can be slow and has security implications.
• Passing the List as Many Parameters. Tedious and error prone, but simple.
• Really Slow Methods. Methods that uses charindex, patindex or LIKE.

I really can't recommend enough to read the article to learn about the tradeoffs among all these options.

To remove disabled attribute use,

 $("#elementID").removeAttr('disabled');

and to add disabled attribute use,

$("#elementID").prop("disabled", true);

Enjoy :)

You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.

this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick); 

I hope it helps.

you can make a jQuery onChange event to get the text from the combobox when the user select one of them:

<script>    
     $( "select" )
     .change(function () {
     var str = "";
     $( "select option:selected" ).each(function() {
     str += $( this ).text() + " ";
     });
     $('#EvaluationName').val(str);
     })
     .change();
 </script>

When you select an option, it will save the text in an Input hidde

  <input type="hidden" id="EvaluationName" name="EvaluationName" value="<?= $Evaluation ?>" />

After that, when you submit the form, just catch up the value of the input

$Evaluation = $_REQUEST['EvaluationName'];

Then you can do wathever you want with the text, for instance save it in a session variable and send it to other page. etc.

Inherit the tableview delegate and datasource. Implement delegates what you need.

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
    }

And Finally implement this delegate

     func tableView(_ tableView: UITableView, didSelectRowAt  
     indexPath: IndexPath) {
     print("row selected : \(indexPath.row)")
  }

In order to avoid hardcoding schema in JPA Entity Java Classes we used orm.xml mapping file in Java EE application deployed in OracleApplicationServer10 (OC4J,Orion). It lays in model.jar/META-INF/ as well as persistence.xml. Mapping file orm.xml is referenced from peresistence.xml with tag

...
  <persistence-unit name="MySchemaPU"  transaction-type="JTA">
    <provider>
     <mapping-file>META-INF/orm.xml</mapping-file>
...

File orm.xml content is cited below:

<?xml version="1.0" encoding="UTF-8"?>

You may have accidentally cloned the repository in https instead of ssh. I've made this mistake numerous times on github. Make sure that you copy the ssh link in the first place when cloning, instead of the https link.

What if you set the timezone of the role you are using?

ALTER ROLE my_db_user IN DATABASE my_database
    SET "TimeZone" TO 'UTC';

Will this be of any use?

About "can it be that 0 errors and IsValid == false": here's MVC source code from https://github.com/Microsoft/referencesource/blob/master/System.Web/ModelBinding/ModelStateDictionary.cs#L37-L41

public bool IsValid {
    get {
        return Values.All(modelState => modelState.Errors.Count == 0);
    }
}

Now, it looks like it can't be. Well, that's for ASP.NET MVC v1.

You can use this code to see the last modified date of a file.

DateTime dt = File.GetLastWriteTime(path);

And this code to see the creation time.

DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");

Git will even determine that it is binary if you have one super-long line in your text file. I broke up a long String, turning it into several source code lines, and suddenly the file went from being 'binary' to a text file that I could see (in SmartGit).

So don't keep typing too far to the right without hitting 'Enter' in your editor - otherwise later on Git will think you have created a binary file.

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

INSERTING

REFRESHING THE TABLE

Try This

public static string PreciseDecimalValue(double Value, int DigitsAfterDecimal)
        {
            string PreciseDecimalFormat = "{0:0.0}";

            for (int count = 2; count <= DigitsAfterDecimal; count++)
            {
                PreciseDecimalFormat = PreciseDecimalFormat.Insert(PreciseDecimalFormat.LastIndexOf('}'), "0");
            }
            return String.Format(PreciseDecimalFormat, Value);
        }

What you want to do is -

strtemp = ";".join(l)

The first line adds a ; to the end of MySpace so that while splitting, it does not give out MySpaceApple This will join l into one string and then you can just-

l1 = strtemp.split(";")

This works because strtemp is a string which has .split()

The best way is to:

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/php-mcrypt-5.3.3-3.el6.x86_64.rpm
yum localinstall php-mcrypt-5.3.3-3.el6.x86_64.rpm

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/libmcrypt-2.5.8-9.el6.x86_64.rpm
yum localinstall libmcrypt-2.5.8-9.el6.x86_64.rpm

or go to: http://dl.fedoraproject.org/pub/epel/6/x86_64/ to match your version check from your info.php that is ok -- done!

Since don't know which version of automake you can use DESTDIR environment variable.
See Makefile to be sure.

For example:

 export DESTDIR="$HOME/Software/LocalInstall" && make -j4 install

The accept attribute specifies a comma-separated list of content types (MIME types) that the target of the form will process correctly. Unfortunately this attribute is ignored by all the major browsers, so it does not affect the browser's file dialog in any way.

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

I've used ZetaHtmlTidy in the past to load random websites and then hit against various parts of the content with xpath (eg /html/body//p[@class='textblock']). It worked well but there were some exceptional sites that it had problems with, so I don't know if it's the absolute best solution.

Add this line before main function:

void swapCase (char* name);

int main()
{
   ...
   swapCase(name);    // swapCase prototype should be known at this point
   ...
}

This is called forward declaration: compiler needs to know function prototype when function call is compiled.

Long press on Google play application

It's not possible to default values in Java. My preferred way to deal with this is to overload the method so you might have something like:

public class MyClass
{
  public int doSomething(int arg1, int arg2)
  {
    ...
  }

  public int doSomething()
  {
    return doSomething(<default value>, <default value>);
  }
}

Following works for me

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Thanks @muhqu for his great answer. In my case not all changes files had permissions changed which prevented the command to work.

$ git diff -p -R --no-ext-diff --no-color | grep -E "^(diff|(old|new) mode)" --color=never
diff --git b/file1 a/file1
diff --git b/file2 a/file2
old mode 100755
new mode 100644
$ git diff -p -R --no-ext-diff --no-color | grep -E "^(diff|(old|new) mode)" --color=never | git apply
warning: file1 has type 100644, expected 100755

The patch would then stop and files would be left untouched.

In case some people have similar problem I solved this by tweaking the command to grep only files with permission changed:

grep -E "^old mode (100644|100755)" -B1 -A1

or for the git alias

git config --global --add alias.permission-reset '!git diff -p -R --no-ext-diff --no-color | grep -E "^old mode (100644|100755)" -B1 -A1 --color=never | git apply'

Right click on the class->select Refactor->Rename

The solution was simply that the URI was malformed (because the location of my project was over a "\\" UNC path). This issue was fixed when I used a local workspace.

I updated the content size to disable vertical scrolling, and the ability to scroll still remained. Then I figured out that I needed to disable vertical bounce too, to disable completly the scroll.

Maybe there are people with this problem too.

One way is by using document.getElementByID, as below -

<body>
  <h1>Adding 'a' and 'b'</h1>

  a: <input type="number" name="a" id="a"><br> b: <input type="number" name="b" id="b"><br>
  <button onclick="add(document.getElementById('a').value,document.getElementById('b').value)">Add</button>

  <script>
    function add(a, b) {
      var sum = parseInt(a, 10) + parseInt(b, 10);
      alert(sum);
    }
  </script>
</body>

try this:

for (char c: string.toCharArray()){
  if (((int)c)>127){
    return false;
  } 
}
return true;

If you can construct the vector after you've gotten the array and array size, you can just say:

std::vector<ValueType> vec(a, a + n);

...assuming a is your array and n is the number of elements it contains. Otherwise, std::copy() w/resize() will do the trick.

I'd stay away from memcpy() unless you can be sure that the values are plain-old data (POD) types.

Also, worth noting that none of these really avoids the for loop--it's just a question of whether you have to see it in your code or not. O(n) runtime performance is unavoidable for copying the values.

Finally, note that C-style arrays are perfectly valid containers for most STL algorithms--the raw pointer is equivalent to begin(), and (ptr + n) is equivalent to end().

A fast and small recap about paths

Absolute paths

http://website.com/assets/image.jpg
IF the image is not on your domain - go look there for image

//website.com/assets/image.jpg
image loaded using http or https protocols

Relative paths

(For internal use if the image is on the same server)

image.jpg
image in the same place as the document calling the image!

./image.jpg
Same as above, image in the same place as the document calling the image!

/assets/image.jpg
Similar to Absolute Paths, just omitting the protocol and domain name
Go search my image starting from my root folder /, than into assets/

assets/image.jpg
this time assets is in the same place as the document, so go into assets for the image

../assets/image.jpg
From where the document is, go one folder back ../ and go into assets

../../image.jpg
go two folders back, there's my image!

../../assets/image.jpg
go two folders back ../../ and than go into assets

As hinted in this question, you have to "open" the lower-level artist API, by storing the figure and axis objects passed by the matplotlib functions you call (the fig, ax and cax variables below). You can then replace the default x- and y-axis ticks using set_xticklabels/set_yticklabels:

from sklearn.metrics import confusion_matrix

labels = ['business', 'health']
cm = confusion_matrix(y_test, pred, labels)
print(cm)
fig = plt.figure()
ax = fig.add_subplot(111)
cax = ax.matshow(cm)
plt.title('Confusion matrix of the classifier')
fig.colorbar(cax)
ax.set_xticklabels([''] + labels)
ax.set_yticklabels([''] + labels)
plt.xlabel('Predicted')
plt.ylabel('True')
plt.show()

Note that I passed the labels list to the confusion_matrix function to make sure it's properly sorted, matching the ticks.

This results in the following figure:

try to clean the eclipse project

If you are actually running into a performance problem I would suggest wrapping the calls that add/remove properties to/from the object with a function that also increments/decrements an appropriately named (size?) property.

You only need to calculate the initial number of properties once and move on from there. If there isn't an actual performance problem, don't bother. Just wrap that bit of code in a function getNumberOfProperties(object) and be done with it.

I just been for 3 days looking for a jquery UI and CSS solution, I merge some code I saw, fix a little, and finally (along the other codes) I could make it work!

Here is a cool way of ensuring zoom in and zoom out with mouse scroll-wheel in the Eclipse Editor. This one takes inspiration from the solution above from naveed ahmad which was not working for me.

1) First download Autohotkey from http://www.autohotkey.com/ and install it, then run it.

2) Then download tarlog-plugins from https://code.google.com/p/tarlog-plugins/downloads/list

3) Put the downloaded .jar file in the eclipse/plugins folder.

4) Restart Eclipse.

5) Add the following Autohotkey script, save it then reload it (right click on Autohotkey icon in taskbar and click "Reload this script")

; Ctrl + MouseWheel zooming in Eclipse Editor.
; Requires Tarlog plugins (https://code.google.com/p/tarlog-plugins/).
#IfWinActive ahk_class SWT_Window0
^WheelUp:: Send ^{NumpadAdd}
^WheelDown:: Send ^{NumpadSub}
#IfWinActive

And you should be done. You can now zoom in or zoom out with ctrl+mousewheel up and ctrl+mousewheel down. The only caveat is that Autohotkey must be running for this solution to work so ensure that it starts with Windows or run it just before firing Eclipse up. Works fine in Eclipse Kepler and Luna.

Shorter:

   Split(stringval,":")(0)

Using ES6 features, you could do something like:

const uniqueAges = [...new Set( array.map(obj => obj.age)) ];

If you do not want variables to be replaced, you need to surround EOL with single quotes.

cat >/tmp/myconfig.conf <<'EOL'
line 1, ${kernel}
line 2, 
line 3, ${distro}
line 4 line
... 
EOL

Previous example:

$ cat /tmp/myconfig.conf 
line 1, ${kernel}
line 2, 
line 3, ${distro}
line 4 line
... 

You could use componentDidMount and componentWillUnmount methods:

import React, { Component } from 'react';
import ReactDOM from 'react-dom';

class MovieItem extends Component
{
    _handleNVEvent = event => {
        ...
    };

    componentDidMount() {
        ReactDOM.findDOMNode(this).addEventListener('nv-event', this._handleNVEvent);
    }

    componentWillUnmount() {
        ReactDOM.findDOMNode(this).removeEventListener('nv-event', this._handleNVEvent);
    }

    [...]

}

export default MovieItem;

I needed real multithreading in Node.js and what worked for me was the threads package. It spawns another process having it's own Node.js message loop, so they don't block each other. The setup is easy and the documentation get's you up and running fast. Your main program and the workers can communicate in both ways and worker "threads" can be killed if needed.

Since multithreading and Node.js is a complicated and widely discussed topic it was quite difficult to find a package that works for my specific requirement. For the record these did not work for me:

• tiny-worker allowed spawning workers, but they seemed to share the same message loop (but it might be I did something wrong - threads had more documentation giving me confidence it really used multiple processes, so I kept going until it worked)
• webworker-threads didn't allow require-ing modules in workers which I needed

And for those asking why I needed real multi-threading: For an application involving the Raspberry Pi and interrupts. One thread is handling those interrupts and another takes care of storing the data (and more).

The use of CultureInfo class worked for me, I hope help you.

    string value = "1200.00";
    CultureInfo culture = new CultureInfo("en-US");
    decimal result = Convert.ToDecimal(value, culture);

Instead of a functor as Mehrdad proposed, you could use a Lambda function.

sort(numbers.begin(), numbers.end(), [](const int a, const int b) {return a > b; });

SELECT firstName, Lastname, MAX(id) as max WHERE YOUR_CONDITIONS_HERE HAVING id=max(id) 

You have to correctly override method equals() from class Object

Edit: I think that my first response was misunderstood probably because I was not too precise. So I decided to to add more explanations.

Why do you have to override equals()? Well, because this is in the domain of a developer to decide what does it mean for two objects to be equal. Reference equality is not enough for most of the cases.

For example, imagine that you have a HashMap whose keys are of type Person. Each person has name and address. Now, you want to find detailed bean using the key. The problem is, that you usually are not able to create an instance with the same reference as the one in the map. What you do is to create another instance of class Person. Clearly, operator == will not work here and you have to use equals().

But now, we come to another problem. Let's imagine that your collection is very large and you want to execute a search. The naive implementation would compare your key object with every instance in a map using equals(). That, however, would be very expansive. And here comes the hashCode(). As others pointed out, hashcode is a single number that does not have to be unique. The important requirement is that whenever equals() gives true for two objects, hashCode() must return the same value for both of them. The inverse implication does not hold, which is a good thing, because hashcode separates our keys into kind of buckets. We have a small number of instances of class Person in a single bucket. When we execute a search, the algorithm can jump right away to a correct bucket and only now execute equals for each instance. The implementation for hashCode() therefore must distribute objects as evenly as possible across buckets.

There is one more point. Some collections require a proper implementation of a hashCode() method in classes that are used as keys not only for performance reasons. The examples are: HashSet and LinkedHashSet. If they don’t override hashCode(), the default Object hashCode() method will allow multiple objects that you might consider "meaningfully equal" to be added to your "no duplicates allowed" set.

Some of the collections that use hashCode()

• HashSet
• LinkedHashSet
• HashMap

Have a look at those two classes from apache commons that will allow you to implement equals() and hashCode() easily

• EqualsBuilder
• HashCodeBuilder

Try enclosing your date into a character string.

 select * 
 from dbo.March2010 A
 where A.Date >= '2010-04-01';

index.php

$url = 'http://[host]/test.php';
$json = json_encode(['name' => 'Jhonn', 'phone' => '128000000000']);

$options = ['http' => [
    'method' => 'POST',
    'header' => 'Content-type:application/json',
    'content' => $json
]];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

test.php

$raw = file_get_contents('php://input');
$data = json_decode($raw, true);
echo $data['name']; // Jhonn

If you have the options -H and -n available (man grep is your friend):

$ cat file
foo
bar
foobar

$ grep -H foo file
file:foo
file:foobar

$ grep -Hn foo file
file:1:foo
file:3:foobar

Options:

-H, --with-filename

Print the file name for each match. This is the default when there is more than one file to search.

-n, --line-number

Prefix each line of output with the 1-based line number within its input file. (-n is specified by POSIX.)

-H is a GNU extension, but -n is specified by POSIX

To use for..of loop on array and retrieve index you can you use array1.indexOf(element) which will return the index value of an element in the loop. You can return both the index and the value using this method.

array1 = ['a', 'b', 'c']
for (element of array1) {
    console.log(array1.indexOf(element), element) // 0 a 1 b 2 c
}

http://jaywcjlove.github.io/hotkeys/

hotkeys('ctrl+a,ctrl+b,r,f', function(event,handler){
    switch(handler.key){
        case "ctrl+a":alert('you pressed ctrl+a!');break;
        case "ctrl+b":alert('you pressed ctrl+b!');break;
        case "r":alert('you pressed r!');break;

    }
});

hotkeys understands the following modifiers: ?, shift, option, ?, alt, ctrl, control, command, and ?.

The following special keys can be used for shortcuts: backspace, tab, clear, enter, return, esc, escape, space, up, down, left, right, home, end, pageup, pagedown, del, delete and f1 through f19.

This can be one of the solution. But your present solution is good enough. You can also add new variables and still keep it clean, which cannot be done with present code.

private static final int INDEX_OF_STRING_PARAM = 0;
private static final int INDEX_OF_INT_PARAM = 1;

public static Object[] myMethod() {
    Object[] values = new Object[2];
    values[INDEX_OF_STRING_PARAM] = "value";
    values[INDEX_OF_INT_PARAM] = 12;
    return values;
}

I always use store.proxy.reader.jsonData or store.proxy.reader.rawData

For example - this return the items nested into a root node called 'data':

var some_store = Ext.data.StoreManager.lookup('some_store_id');
Ext.each(some_store.proxy.reader.rawData.data, function(obj, i){
   console.info(obj);
});

This only works immediately after a store read-operation (while not been manipulated yet).

Taken from above:

from scipy.stats import norm

0.9750021048517795
>>> norm.cdf(-1.96)

For a two-tailed test:

Import numpy as np
z = 1.96
p_value = 2 * norm.cdf(-np.abs(z))
0.04999579029644087

I'm new with Android and the project appcompat_v7 always be created when I create new Android application project makes me so uncomfortable.

This is just a walk around. Choose Project Properties -> Android then at Library box just remove appcompat_v7_x and add appcompat_v7. Now you can delete appcompat_v7_x.

Uncheck Create Activity in create project wizard doesn't work, because when creating activity by wizard the appcompat_v7_x appear again. My ADT's version is v22.6.2-1085508.
I'm sorry if my English is bad.

This is how I got it working with loading remote content that needs to be refreshed:

$(document).ready(function () {
    var loadingContent = '<div class="modal-header"><h1>Processing...</h1></div><div class="modal-body"><div class="progress progress-striped active"><div class="bar" style="width: 100%;"></div></div></div>';

    // This is need so the content gets replaced correctly.
    $("#myModal").on("show.bs.modal", function (e) {
        $(this).find(".modal-content").html(loadingContent);        
        var link = $(e.relatedTarget);
        $(this).find(".modal-content").load(link.attr("href"));
    });    

    $("#myModal2").on("hide.bs.modal", function (e) {
        $(this).removeData('bs.modal');
    });
});

Basically, just replace the modal content while it's loading with a loading message. The content will then be replaced once it's finished loading.

I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.

Finally i have found a solution with javascript here is the link bellow :-

EDIT (after comment): the below will solve the coding issue, but is highly not recommended to use this approach because a linear regression model is a very poor classifier, which will very likely not separate the classes correctly.

Read the well written answer below by @desertnaut, explaining why this error is an hint of something wrong in the machine learning approach rather than something you have to 'fix'.

@Martin Konecny's answer provides the correct answer, but - as he mentions - it only works if the actual script is not invoked through a symlink residing in a different directory.

This answer covers that case: a solution that also works when the script is invoked through a symlink or even a chain of symlinks:

Linux / GNU readlink solution:

If your script needs to run on Linux only or you know that GNU readlink is in the $PATH, use readlink -f, which conveniently resolves a symlink to its ultimate target:

 scriptDir=$(dirname -- "$(readlink -f -- "$BASH_SOURCE")")

^{Note that GNU readlink has 3 related options for resolving a symlink to its ultimate target's full path: -f (--canonicalize), -e (--canonicalize-existing), and -m (--canonicalize-missing) - see man readlink.
Since the target by definition exists in this scenario, any of the 3 options can be used; I've chosen -f here, because it is the most well-known one.}

Multi-(Unix-like-)platform solution (including platforms with a POSIX-only set of utilities):

If your script must run on any platform that:

• has a readlink utility, but lacks the -f option (in the GNU sense of resolving a symlink to its ultimate target) - e.g., macOS.

  • macOS uses an older version of the BSD implementation of readlink; note that recent versions of FreeBSD/PC-BSD do support -f.

• does not even have readlink, but has POSIX-compatible utilities - e.g., HP-UX (thanks, @Charles Duffy).

The following solution, inspired by https://stackoverflow.com/a/1116890/45375, defines helper shell function, rreadlink(), which resolves a given symlink to its ultimate target in a loop - this function is in effect a POSIX-compliant implementation of GNU readlink's -e option, which is similar to the -f option, except that the ultimate target must exist.

Note: The function is a bash function, and is POSIX-compliant only in the sense that only POSIX utilities with POSIX-compliant options are used. For a version of this function that is itself written in POSIX-compliant shell code (for /bin/sh), see here.

• If readlink is available, it is used (without options) - true on most modern platforms.

• Otherwise, the output from ls -l is parsed, which is the only POSIX-compliant way to determine a symlink's target.
  Caveat: this will break if a filename or path contains the literal substring -> - which is unlikely, however.
  (Note that platforms that lack readlink may still provide other, non-POSIX methods for resolving a symlink; e.g., @Charles Duffy mentions HP-UX's find utility supporting the %l format char. with its -printf primary; in the interest of brevity the function does NOT try to detect such cases.)

• An installable utility (script) form of the function below (with additional functionality) can be found as rreadlink in the npm registry; on Linux and macOS, install it with [sudo] npm install -g rreadlink; on other platforms (assuming they have bash), follow the manual installation instructions.

If the argument is a symlink, the ultimate target's canonical path is returned; otherwise, the argument's own canonical path is returned.

  while :; do # Resolve potential symlinks until the ultimate target is found.

      fname=$(command basename -- "$target") # Extract filename.

      if [[ -L $fname ]]; then
        # Extract [next] target path, which is defined
        # relative to the symlink's own directory.
        if [[ -n $readlinkexe ]]; then # Use `readlink`.

        else # `readlink` utility not available.
          # Parse `ls -l` output, which, unfortunately, is the only POSIX-compliant 
          # way to determine a symlink's target. Hypothetically, this can break with
          # filenames containig literal ' -> ' and embedded newlines.
          target=$(command ls -l -- "$fname")
          target=${target#* -> }
        fi
        continue # Resolve [next] symlink target.
      fi
      break # Ultimate target reached.
  done
  targetDir=$(command pwd -P) # Get canonical dir. path
  # Output the ultimate target's canonical path.
  # Note that we manually resolve paths ending in /. and /.. to make sure we
  # have a normalized path.
  if [[ $fname == '.' ]]; then
    command printf '%s\n' "${targetDir%/}"
  elif  [[ $fname == '..' ]]; then
    # Caveat: something like /var/.. will resolve to /private (assuming
    # /var@ -> /private/var), i.e. the '..' is applied AFTER canonicalization.
    command printf '%s\n' "$(command dirname -- "${targetDir}")"
  else
    command printf '%s\n' "${targetDir%/}/$fname"
  fi
)

# Determine ultimate script dir. using the helper function.
# Note that the helper function returns a canonical path.
scriptDir=$(dirname -- "$(rreadlink "$BASH_SOURCE")")

If you have installed VS2012 as well, the old cvtres file will no longer work.

Try removing the file (I simply renamed):
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\BIN\cvtres.exe

You can also debug using the /VERBOSE linker option in order to get more information regarding the linker error. There you should see an error message that the invoke to cvtres fails.

You would need to use Javascript for this. You can set the style of the background-image for the body like so.

var body = document.getElementsByTagName('body')[0];
body.style.backgroundImage = 'url(http://localhost/background.png)';

Just make sure you replace the URL with the actual URL.

I was getting the same error while connecting my "hr" user of ORCLPDB which is a pluggable database.

First, get hostname and port number by typing a command lsnrctl status on windows command prompt. In my case, it was 127.0.0.1 with port number as 1521

Second, enter the below command with your hostname and port number:

sqlplus username/password@HostName:Port Number/PluggableDatabaseName.

For example:

sqlplus hr/[email protected]:1521/ORCLPDB.

My try is combined solution.

string = string.replace(',', '.').replace(/[^\d\.]/g, "").replace(/\./, "x").replace(/\./g, "").replace(/x/, ".");
string = Math.round( parseFloat(string) * 100) / 100;

First line solution from here: regex replacing multiple periods in floating number . It replaces comma "," with dot "." ; Replaces first comma with x; Removes all dots and replaces x back to dot.

Second line cleans numbers after dot.

Try this:

var src = DateTime.Now;
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);

I would not advise hacking browser-specific things manually with JS. Either use a javascript library like "prototype" or "jquery", which will handle all the specific issues transparently.

Or use these libs to determine the browser type if you really must.

Also see Browser & version in prototype library?

Or maybe you can use the setInterval function, to call a particular function, after the specified number of milliseconds. Just do a google for the setInterval prototype.I don't quite recollect it.

What is the secret key

The secret key is combined with the header and the payload to create a unique hash. You are only able to verify this hash if you have the secret key.

How to generate the key

You can choose a good, long password. Or you can generate it from a site like this.

Example (but don't use this one now):

8Zz5tw0Ionm3XPZZfN0NOml3z9FMfmpgXwovR9fp6ryDIoGRM8EPHAB6iHsc0fb

To get country code

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

public String makeServiceCall() {
    String response = null;
    String reqUrl = "https://ipinfo.io/country";
    try {
        URL url = new URL(reqUrl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        // read the response
        InputStream in = new BufferedInputStream(conn.getInputStream());
        response = convertStreamToString(in);
    } catch (MalformedURLException e) {
        Log.e(TAG, "MalformedURLException: " + e.getMessage());
    } catch (ProtocolException e) {
        Log.e(TAG, "ProtocolException: " + e.getMessage());
    } catch (IOException e) {
        Log.e(TAG, "IOException: " + e.getMessage());
    } catch (Exception e) {
        Log.e(TAG, "Exception: " + e.getMessage());
    }
    return response;
}

This works because Integer::min resolves to an implementation of the Comparator<Integer> interface.

The method reference of Integer::min resolves to Integer.min(int a, int b), resolved to IntBinaryOperator, and presumably autoboxing occurs somewhere making it a BinaryOperator<Integer>.

And the min() resp max() methods of the Stream<Integer> ask the Comparator<Integer> interface to be implemented.
Now this resolves to the single method Integer compareTo(Integer o1, Integer o2). Which is of type BinaryOperator<Integer>.

And thus the magic has happened as both methods are a BinaryOperator<Integer>.

They don't exist in MySQL do they? Just use a temp table:

CREATE PROCEDURE my_proc () BEGIN 

CREATE TEMPORARY TABLE TempTable (myid int, myfield varchar(100)); 
INSERT INTO TempTable SELECT tblid, tblfield FROM Table1; 

/* Do some more stuff .... */

From MySQL here

"You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.)"

By using jQuery to generate a new image with the image's src, and assigning the load method directly to that, the load method is successfully called when jQuery finishes generating the new image. This is working for me in IE 8, 9 and 10

$('<img />', {
    "src": $("#img").attr("src")
}).load(function(){
    // Do something
});

As suggested by Adam Miller in the comments, I'll add another solution.

The MailMessage(String from, String to) constructor accepts a comma separated list of addresses. So if you happen to have already a comma (',') separated list, the usage is as simple as:

MailMessage Msg = new MailMessage(fromMail, addresses);

In this particular case, we can replace the ';' for ',' and still make use of the constructor.

MailMessage Msg = new MailMessage(fromMail, addresses.replace(";", ","));

Whether you prefer this or the accepted answer it's up to you. Arguably the loop makes the intent clearer, but this is shorter and not obscure. But should you already have a comma separated list, I think this is the way to go.

Personally, I usually go with:

select * 
from   t1
where  date between trunc( :somedate )          -- 00:00:00
            and     trunc( :somedate ) + .99999 -- 23:59:59

Don't use jQuery, just use javascript for correct result:

This includes scrollbar width/height:

var windowWidth = window.innerWidth;_x000D_
var windowHeight = window.innerHeight;_x000D_
_x000D_
alert('viewport width is: '+ windowWidth + ' and viewport height is:' + windowHeight);

This excludes scrollbar width/height:

var widthWithoutScrollbar = document.body.clientWidth;_x000D_
var heightWithoutScrollbar = document.body.clientHeight;_x000D_
_x000D_
alert('viewport width is: '+ widthWithoutScrollbar + ' and viewport height is:' + heightWithoutScrollbar);

Please also make sure to use await and async in you method. You can get this error if your object are not serialized properly.

UPDATE:

All of the above answers won't work for the repeated values, @BenBolker's answer using duplicated() predicate solves this:

full_vector[!full_vector %in% searched_vector | duplicated(full_vector)]

Original Answer: here I write a little function for this:

exclude_val<-function(full_vector,searched_vector){

      found=c()

      for(i in full_vector){  

        if(any(is.element(searched_vector,i))){
          searched_vector[(which(searched_vector==i))[1]]=NA
        }
        else{
          found=c(found,i)
        }
    }

    return(found)
}

so, let's say full_vector=c(1,2,3,4,1) and searched_vector=c(1,2,3).

exclude_val(full_vector,searched_vector) will return (4,1), however above answers will return just (4).

change

public static final String URL = "http://api-Location";

to

public static final String URL = "https://api-Location"

it's happen because i'm using 000webhostapp app

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.

Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.

You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.

You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

There are many tools available

1. google maps API as like all had written
2. use this data "https://simplemaps.com/data/world-cities" download free version and convert excel to JSON with some online converter like "http://beautifytools.com/excel-to-json-converter.php"
3. use IP address which is not good because using IP address of someone may not good users think that you can hack them.

other free and paid tools are available also

If your string is in ISO8601 format and you have Python 3.7+ you can use the following simple code:

import datetime.date

aDate = datetime.date.fromisoformat('2020-10-04')

for dates and

import datetime.datetime

aDateTime = datetime.datetime.fromisoformat('2020-10-04 22:47:00')

for strings containing date and time. If timestamps are included the function datetime.datetime.isoformat() supports the following format

YYYY-MM-DD[*HH[:MM[:SS[.fff[fff]]]][+HH:MM[:SS[.ffffff]]]]

where * matches any single character. See also here and here

Different database systems have different names for the same type of index, so be careful with this. For example, what SQL Server and Sybase call "clustered index" is called in Oracle an "index-organised table".

This disables the script errors and also disables other windows.. such as the NTLM login window or the client certificate accept window. The below will suppress only javascript errors.

// Hides script errors without hiding other dialog boxes.
private void SuppressScriptErrorsOnly(WebBrowser browser)
{
    // Ensure that ScriptErrorsSuppressed is set to false.
    browser.ScriptErrorsSuppressed = false;

    // Handle DocumentCompleted to gain access to the Document object.
    browser.DocumentCompleted +=
        new WebBrowserDocumentCompletedEventHandler(
            browser_DocumentCompleted);
}

private void browser_DocumentCompleted(object sender, 
    WebBrowserDocumentCompletedEventArgs e)
{
    ((WebBrowser)sender).Document.Window.Error += 
        new HtmlElementErrorEventHandler(Window_Error);
}

private void Window_Error(object sender, 
    HtmlElementErrorEventArgs e)
{
    // Ignore the error and suppress the error dialog box. 
    e.Handled = true;
}

It's not totally clear from your question, but I'm assuming you saying that you have a file where each line of that file is a filename. And each filename is something like this:

\u0048\u0065\u006C\u006C\u006F

In other words, the characters in the file of filenames are \, u, 0, 0, 4, 8 and so on.

If so, what you're seeing is expected. Java only translates \uXXXX sequences in string literals in source code (and when reading in stored Properties objects). When you read the contents you file you will have a string consisting of the characters \, u, 0, 0, 4, 8 and so on and not the string Hello.

So you will need to parse that string to extract the 0048, 0065, etc. pieces and then convert them to chars and make a string from those chars and then pass that string to the routine that opens the file.

You can use an anonymous function;

setInterval(function() { funca(10,3); },500);

You need a table variable:

declare @values table
(
    Value varchar(1000)
)

insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')

select blah
from foo
where myField in (select value from @values)

Use the apache commons-lang3 lib

import org.apache.commons.lang3.exception.ExceptionUtils;

//...

String[] ss = ExceptionUtils.getRootCauseStackTrace(e);
logger.error(StringUtils.join(ss, System.lineSeparator()));

JMeter is using java SimpleDateFormat

For UTC with timezone use this

${__time(yyyy-MM-dd'T'hh:mm:ssX)}

When you are defining styles for division which is positioned absolutely, they specifying margins are useless. Because they are no longer inside the regular DOM tree.

You can use float to do the trick.

.divtagABS {
    float: left;
    margin-left: auto;  
    margin-right:auto;
 }

You can create a thread just like this:

 Thread thread = new Thread(new Runnable() {
                    public void run() {

                       }
                    });
                thread.start();

Also, you can use Runnable, Asyntask, Timer, TimerTaks and AlarmManager to excecute Threads.

you need to add 3 dependency ( API+ API implementation + log4j dependency)

maxlenght - input type text

<input type="email" name="email" maxlength="50">

using jQuery:

$("input").attr("maxlength", 50)

maxlenght - input type number

JS

function limit(element, max) {    
    var max_chars = max;
    if(element.value.length > max_chars) {
        element.value = element.value.substr(0, max_chars);
    } 
}

HTML

<input type="number" name="telefono" onkeydown="limit(this, 20);" onkeyup="limit(this, 20);">

I don't know your exact need for this, but if you are also using .NET, couldn't you use Html Agility Pack?

Excerpt:

It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML.
