I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

Java - its independence is not only from the operating system, but also from the vendor.

Therefore, you should be able to deploy your application on different application servers. JPA is implemented in any Java EE- compliant application server and it allows to swap application servers, but then the implementation is also changing. A Hibernate application may be easier to deploy on a different application server.

The "14" and "6" in those driver names refer to the JVM they were written for. If you're still using JDK 1.4 I'd say you have a serious problem and need to upgrade. JDK 1.4 is long past its useful support life. It didn't even have generics! JDK 6 u21 is the current production standard from Oracle/Sun. I'd recommend switching to it if you haven't already.

You don't need jquery, just use yourstring.length. See reference here and also here.

Update:

To support unicode strings, length need to be computed as following:

[...""].length

or create an auxiliary function

function uniLen(s) {
    return [...s].length
}

I had the same problem.
The cause for me was that the Command option in Configuration Properties | Debugging had been reset to its default value.

This might be caused due to different reasons, some user have mentioned other possibilities and I add my case:

I got this error when using multi-threading (both std::pthread and std::thread) and the error occurred because I forgot to lock a variable which multi threads may change at the same time. this error comes randomly in some runs but not all because ... you know accident between to threads is random.

That variable in my case was a global std::vector which I tried to push_back() something into it in a function called by threads.. and then I used a std::mutex and never got this error again.

may help some

Do you want to know if a type is the same type as int64_t or do you want to know if something is 64 bits? Based on your proposed solution, I think you're asking about the latter. In that case, I would do something like

template<typename T>
bool is_64bits() { return sizeof(T) * CHAR_BIT == 64; } // or >= 64

To apply to an entire list, use

ul.space_list li { margin-bottom: 1em; }

Then, in the html:

<ul class=space_list>
<li>A</li>
<li>B</li>
</ul>

from subprocess import call

def cp_dir(source, target):
    call(['cp', '-a', source, target]) # Linux

cp_dir('/a/b/c/', '/x/y/z/')

It works for me. Basically, it executes shell command cp.

td:nth-of-type(n) { padding-right: 10px;}

it will adjust auto space between all td

Width:100% and text-align:center would work in my experience

<p style="display:block; line-height: 70px; width:100%; text-align:center; margin:0 auto;"><button type="submit" class="btn">Confirm</button></p>

I had the same issue and I solved it by installing latest npm version:

npm install -g npm@latest

and then change the webpack.config.js file to solve

- configuration.resolve.extensions[0] should not be empty.

now resolve extension should look like:

resolve: {
    extensions: [ '.js', '.jsx']
},

then run npm start.

Refer this:

@RequestMapping(value="download", method=RequestMethod.GET)

// Get your file stream from wherever.
InputStream myStream = someClass.returnFile();

// Set the content type and attachment header.
response.addHeader("Content-disposition", "attachment;filename=myfilename.txt");
response.setContentType("txt/plain");

// Copy the stream to the response's output stream.
IOUtils.copy(myStream, response.getOutputStream());
response.flushBuffer();
}

You can get the second method to achieve the same effect by:

var mySecondDiv = $('<div></div>');
$(mySecondDiv).find('div').attr('id', 'mySecondDiv');
$('#myDiv').append(mySecondDiv);

Luca mentioned that html() just inserts hte HTML which results in faster performance.

In some occassions though, you would opt for the second option, consider:

// Clumsy string concat, error prone
$('#myDiv').html("<div style='width:'" + myWidth + "'px'>Lorem ipsum</div>");

// Isn't this a lot cleaner? (though longer)
var newDiv = $('<div></div>');
$(newDiv).find('div').css('width', myWidth);
$('#myDiv').append(newDiv);

$("input").on("keydown",function search(e) {
    if(e.keyCode == 13) {
        alert($(this).val());
    }
});

jsFiddle example : http://jsfiddle.net/NH8K2/1/

In Python 2.x - .items() returned a list of (key, value) pairs. In Python 3.x, .items() is now an itemview object, which behaves different - so it has to be iterated over, or materialised... So, list(dict.items()) is required for what was dict.items() in Python 2.x.

Python 2.7 also has a bit of a back-port for key handling, in that you have viewkeys, viewitems and viewvalues methods, the most useful being viewkeys which behaves more like a set (which you'd expect from a dict).

Simple example:

common_keys = list(dict_a.viewkeys() & dict_b.viewkeys())

Will give you a list of the common keys, but again, in Python 3.x - just use .keys() instead.

Python 3.x has generally been made to be more "lazy" - i.e. map is now effectively itertools.imap, zip is itertools.izip, etc.

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

When doing recursive replacement, the path and filename need to be included:

Get-ChildItem -Recurse | ForEach {  (Get-Content $_.PSPath | 
ForEach {$ -creplace "old", "new"}) | Set-Content $_.PSPath }

This wil replace all "old" with "new" case-sensitive in all the files of your folders of your current directory.

The select module helps you determine where the next useful input is.

However, you're almost always happier with separate threads. One does a blocking read the stdin, another does wherever it is you don't want blocked.

Async means asynchronous and you should use that most of the time. You should never call sync on main thread cause it will lock up your UI until the task is completed. You Here is a better way to do this in Swift:

runThisInMainThread { () -> Void in
    // Run your code like this:
    self.doStuff()
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

I figured it out from the PostgreSQL docs, the exact syntax is:

ALTER TABLE the_table ADD CONSTRAINT constraint_name UNIQUE (thecolumn);

Thanks Fred.

You can use a background image to accomplish this;

From MDN - Background Size: Contain:

This keyword specifies that the background image should be scaled to be as large as possible while ensuring both its dimensions are less than or equal to the corresponding dimensions of the background positioning area.

Demo

CSS:

#im {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-image: url("path/to/img");
    background-repeat: no-repeat;
    background-size: contain;
}

HTML:

<div id="wrapper">
    <div id="im">
    </div>
</div>

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

From axios docs you have baseURL and url

baseURL will be prepended to url when making requests. So you can define baseURL as http://127.0.0.1:8000 and make your requests to /url

 // `url` is the server URL that will be used for the request
 url: '/user',

 // `baseURL` will be prepended to `url` unless `url` is absolute.
 // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
 // to methods of that instance.
 baseURL: 'https://some-domain.com/api/',

Using guava:

List<String> stringList=Lists.transform(list,new Function<Object,String>(){
    @Override
    public String apply(Object arg0) {
        if(arg0!=null)
            return arg0.toString();
        else
            return "null";
    }
});

If there are multiple commits, you can use git rebase -i to squash two commits into one.

If there are only two commits you want to merge, and they are the "most recent two", the following commands can be used to combine the two commits into one:

git reset --soft "HEAD^"
git commit --amend

There are several ways to try to prevent line breaks, and the phrase “a newer construct” might refer to more than one way—that’s actually the most reasonable interpretation. They probably mostly think of the CSS declaration white-space:nowrap and possibly the no-break space character. The different ways are not equivalent, far from that, both in theory and especially in practice, though in some given case, different ways might produce the same result.

There is probably nothing real to be gained by switching from the HTML attribute to the somewhat clumsier CSS way, and you would surely lose when style sheets are disabled. But even the nowrap attribute does no work in all situations. In general, what works most widely is the nobr markup, which has never made its way to any specifications but is alive and kicking: <td><nobr>...</nobr></td>.

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments["<host>"], arguments["<port>"])

You don't need ng-checked when you use ng-model. If you're performing CRUD on your HTML Form, just create a model for CREATE mode that is consistent with your EDIT mode during the data-binding:

CREATE Mode: Model with default values only

$scope.dataModel = {
   isItemSelected: true,
   isApproved: true,
   somethingElse: "Your default value"
}

EDIT Mode: Model from database

$scope.dataModel = getFromDatabaseWithSameStructure()

Then whether EDIT or CREATE mode, you can consistently make use of your ng-model to sync with your database.

Country Data NPM Package.

If you're using node or NPM in general, you should take a look at the thorough Country Data package.

Since you're trying to get the Country from a phone number, you face two major obstacles:

1. Parsing the phone number to get the Country code.

2. Handling situations where a Country code can belong to more than one Country. e.g. Country Code of "+1" belongs to the United States and Canada.

However, the Country Data package will allow you to do something like this:

var CountryDataLookup = require('country-data').lookup;

lookup.countries({countryCallingCodes: '+1'})

And these are the returning objects:

[ { alpha2: 'CA',
    alpha3: 'CAN',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'CAD' ],
    ioc: 'CAN',
    languages: [ 'eng', 'fra' ],
    name: 'Canada',
    status: 'assigned' },
  { alpha2: 'UM',
    alpha3: 'UMI',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'USD' ],
    ioc: '',
    languages: [ 'eng' ],
    name: 'United States Minor Outlying Islands',
    status: 'assigned' },
  { alpha2: 'US',
    alpha3: 'USA',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'USD' ],
    ioc: 'USA',
    languages: [ 'eng' ],
    name: 'United States',
    status: 'assigned' } ]

AutoScroll is really the solution! You just have to set AutoScrollMargin to 0, 1000 or something like this, then use it to scroll down and add buttons and items there!

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()

What is saying is that your list is a List of unespecified objects. That is that Java does not know what kind of objects are inside the list. Then when you want to iterate the list you have to cast every element, to be able to access the properties of that element (in this case, String).

In general is a better idea to parametrize the collections, so you don't have conversion problems, you will only be able to add elements of the parametrized type and your editor will offer you the appropiate methods to select.

private static List<String> list = new ArrayList<String>();

You're looking for the MemoryStream.Write method.

For example, the following code will write the contents of a byte[] array into a memory stream:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream();
stream.Write(myByteArray, 0, myByteArray.Length);

Alternatively, you could create a new, non-resizable MemoryStream object based on the byte array:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream(myByteArray);

Sometimes simple escaping is not possible with the characters you've listed. For example, using a backslash to escape a bracket isn't going to work in the left hand side of a substitution string in sed, namely

sed -e 's/foo\(bar/something_else/'

I tend to just use a simple character class definition instead, so the above expression becomes

sed -e 's/foo[(]bar/something_else/'

which I find works for most regexp implementations.

BTW Character classes are pretty vanilla regexp components so they tend to work in most situations where you need escaped characters in regexps.

Edit: After the comment below, just thought I'd mention the fact that you also have to consider the difference between finite state automata and non-finite state automata when looking at the behaviour of regexp evaluation.

You might like to look at "the shiny ball book" aka Effective Perl (sanitised Amazon link), specifically the chapter on regular expressions, to get a feel for then difference in regexp engine evaluation types.

Not all the world's a PCRE!

Anyway, regexp's are so clunky compared to SNOBOL! Now that was an interesting programming course! Along with the one on Simula.

Ah the joys of studying at UNSW in the late '70's! (-:

std::fill(a.begin(),a.end(),0);

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length.

double sum = 0.0;
int length = 0;

for( double number : numbers ) {
    sum += number;
    length++;
}

return sum/length;

Variance is calculated similarly. Standard deviation is simply the square root of the variance:

double stddev = Math.sqrt( variance );

Function RemoveCharacter(ByVal stringToCleanUp, ByVal characterToRemove)
  ' replace the target with nothing
  ' Replace() returns a new String and does not modify the current one
  Return stringToCleanUp.Replace(characterToRemove, "")
End Function

There are two ways to capture network traffic directly from an Android emulator:

1. Copy and run an ARM-compatible tcpdump binary on the emulator, writing output to the SD card, perhaps (e.g. tcpdump -s0 -w /sdcard/emulator.cap).

2. Run emulator -tcpdump emulator.cap -avd my_avd to write all the emulator's traffic to a local file on your PC

In both cases you can then analyse the pcap file with tcpdump or Wireshark as normal.

for example String.

String str= "abc";//a object of string is created
str  = str + "def";// a new object of string is created and assigned to str

Since you did not provide an attribute for the 'item' value, I am assuming a class is being used:

<div class='item1'>
  <span>This is my name</span>
</div>

alert($(".item span").text());

Make sure you wait for the DOM to load to use your code, in jQuery you use the ready() function for that:

<html>
 <head>
  <title>jQuery test</title>
  <!-- script that inserts jquery goes here -->
  <script type='text/javascript'>
    $(document).ready(function() { alert($(".item span").text()); });
  </script>
</head>
<body>
 <div class='item1'>
   <span>This is my name</span>
 </div>
</body>

SELECT *

WHERE pw='correct'

Which parameter between (data / json / files) should be used,it's actually depends on a request header named ContentType(usually check this through developer tools of your browser),

when the Content-Type is application/x-www-form-urlencoded, code should be:

requests.post(url, data=jsonObj)

when the Content-Type is application/json, your code is supposed to be one of below:

requests.post(url, json=jsonObj)

requests.post(url, data=jsonstr, headers={"Content-Type":"application/json"})

when the Content-Type is multipart/form-data, it's used to upload files, so your code should be:

requests.post(url, files=xxxx)

java.lang.String class has method substring not substr , thats the error in your program.

Moreover you can do this in one single line if you are ok in using regular expression.

a.replaceAll("\\s+","");

#FFFFEEE is not a correct color code. Try with #FFFFEE instead.

Actually you have 2 problems here: First is that you don't have ssh installed, second is that you don't know how to deploy

Install SSH

It seems that ssh is not installed on your computer.

You can install openssh from here : http://openssh.en.softonic.com/download

Generate your key

Than you will have to geneate your ssh-key. There's a good tutorial about this here:

https://help.github.com/articles/generating-ssh-keys#platform-windows

Deploy

To deploy, you just have to push your code over git. Something like this:

git push fort master

If you get permission denied, be sure that you have put your public_key in the dashboard in the git tab.

SSH

The ssh command gives you access to your remote node. You should have received a password by email and now that you have ssh installed, you should be asked for a password when trying to connect. just input that password. If you want to use your private ssh key to connect to your server rather then typing that password, you can follow this : http://fortrabbit.com/docs/how-to/ssh-sftp/enable-public-key-authentication

Runtime is somewhat opposite to design-time and compile-time/link-time. Historically it comes from slow mainframe environment where machine-time was expensive.

I got this error message when I entered a number (999999) that was out of the range I'd set for the form.

<input type="number" ng-model="clipInMovieModel" id="clipInMovie" min="1" max="10000">

The other respondents are correct in describing the double leading and trailing underscores as a naming convention for "special" or "magic" methods.

While you can call these methods directly ([10, 20].__len__() for example), the presence of the underscores is a hint that these methods are intended to be invoked indirectly (len([10, 20]) for example). Most python operators have an associated "magic" method (for example, a[x] is the usual way of invoking a.__getitem__(x)).

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html

• std::sample, sampling from a range?

Container Improvements

• try_emplace and insert_or_assign

  • gives better guarantees in some cases where spurious move/copy would be bad

• Splicing for map<>, unordered_map<>, set<>, and unordered_set<>

  • Move nodes between containers cheaply.
  • Merge whole containers cheaply.

• non-const .data() for string.

• non-member std::size, std::empty, std::data

  • like std::begin/end

• Minimal incomplete type support in containers

• Contiguous iterator "concept"

• constexpr iterators

• The emplace family of functions now returns a reference to the created object.

• unique_ptr<T[]> fixes and other unique_ptr tweaks.
• weak_from_this and some fixed to shared from this

Other std datatype improvements:

• {} construction of std::tuple and other improvements
• TriviallyCopyable reference_wrapper, can be performance boost

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Further reference:

• papers grouped by year; not all accepted

• https://isocpp.org/files/papers/p0636r0.html

  • Should be updated to "Modifications to existing features" here.

I always thought this was one of the better articles on the subject. It includes the following example that I think makes it clear and includes the frequently overlooked @@trancount which is needed for reliable nested transactions

PRINT 'BEFORE TRY'
BEGIN TRY
    BEGIN TRAN
     PRINT 'First Statement in the TRY block'
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(1, 'Account1',  10000)
     UPDATE dbo.Account SET Balance = Balance + CAST('TEN THOUSAND' AS MONEY) WHERE AccountId = 1
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(2, 'Account2',  20000)
     PRINT 'Last Statement in the TRY block'
    COMMIT TRAN
END TRY
BEGIN CATCH
    PRINT 'In CATCH Block'
    IF(@@TRANCOUNT > 0)
        ROLLBACK TRAN;

    THROW; -- raise error to the client
END CATCH
PRINT 'After END CATCH'
SELECT * FROM dbo.Account WITH(NOLOCK)
GO

The way you tried first is actually directly possible with numpy:

import numpy
myArray = numpy.array([10,20,30,40,50,60,70,80,90])
myInt = 10
newArray = myArray/myInt

If you do such operations with long lists and especially in any sort of scientific computing project, I would really advise using numpy.

On Windows 64bits it´s works:

1. Download opencv-3.0 (beta), MinGW (command line tool);
2. Add above respective bin folder to PATH var;
3. Create an folder "release" (could be any name) into ;
4. Into created folder, open prompt terminal and exec the below commands;

5. Copy and Past this command

   cmake -G "MinGW Makefiles" -D CMAKE_CXX_COMPILER=mingw32-g++.exe -D WITH_IPP=OFF MAKE_MAKE_PROGRAM=mingw32-make.exe ..\

6. Execute this command mingw32-make

7. Execute this command mingw32-make install

DONE

According to nginx documentation

there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else

So you could define something like

location ~ (dir1|file2\.php) { 
    # empty
}

location / {
    rewrite ^/(.*) http://example.com/$1 permanent; 
}

You can check for yourself.

In this fiddle, I ran a test to demonstrate the blocking nature of await, as opposed to Promise.all which will start all of the promises and while one is waiting it will go on with the others.

Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.

On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.

Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.

If I understand what you're trying to do correctly, then I don't think this is possible with CSS while keeping the children absolutely positioned.

Absolutely positioned elements are completely removed from the document flow, and thus their dimensions cannot alter the dimensions of their parents.

If you really had to achieve this affect while keeping the children as position: absolute, you could do so with JavaScript by finding the height of the absolutely positioned children after they have rendered, and using that to set the height of the parent.

Alternatively, just use float: left/float:right and margins to get the same positioning effect while keeping the children in the document flow, you can then use overflow: hidden on the parent (or any other clearfix technique) to cause its height to expand to that of its children.

article {
    position: relative;
    overflow: hidden;
}

.one {
    position: relative;
    float: left;
    margin-top: 10px;
    margin-left: 10px;
    background: red;
    width: 30px;
    height: 30px;
}

.two {
    position: relative;
    float: right;
    margin-top: 10px;
    margin-right: 10px;
    background: blue;
    width: 30px;
    height: 30px;
}

position: absolute will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static.

Have your four divs nested inside the target div, give the target div position: relative, and use position: absolute on the others.

Structure your HTML similar to this:

<div id="container">
  <div class="top left"></div>
  <div class="top right"></div>
  <div class="bottom left"></div>
  <div class="bottom right"></div>
</div>

And this CSS should work:

#container {
  position: relative;
}

#container > * {
  position: absolute;
}

.left {
  left: 0;
}

.right {
  right: 0;
}

.top {
  top: 0;
}

.bottom {
  bottom: 0;
}

...

The empty string is false as a rule.

Apparently the empty string is not respected as empty in all browsers and the presence of the checked attribute is taken to mean checked. So the entire attribute must either be present or omitted.

do you like it

print(fr"\{''}")

or how about this

print(r"\ "[0])

You can just subtract the vectors and then innerproduct.

Following your example,

a = numpy.array((xa, ya, za))
b = numpy.array((xb, yb, zb))

tmp = a - b
sum_squared = numpy.dot(tmp.T, tmp)
result = numpy.sqrt(sum_squared)

Between execution of left != null and queue.add(left) another thread could have changed the value of left to null.

To work around this you have several options. Here are some:

1. Use a local variable with smart cast:

    val node = left
    if (node != null) {
        queue.add(node)
    }
   

2. Use a safe call such as one of the following:

    left?.let { node -> queue.add(node) }
    left?.let { queue.add(it) }
    left?.let(queue::add)
   

3. Use the Elvis operator with return to return early from the enclosing function:

    queue.add(left ?: return)
   

   Note that break and continue can be used similarly for checks within loops.

Here's how to do it:

var myVideo = document.getElementById("my-video")    
myVideo.controls = false;

The FailedPreconditionError arises because the program is attempting to read a variable (named "Variable_1") before it has been initialized. In TensorFlow, all variables must be explicitly initialized, by running their "initializer" operations. For convenience, you can run all of the variable initializers in the current session by executing the following statement before your training loop:

tf.initialize_all_variables().run()

Note that this answer assumes that, as in the question, you are using tf.InteractiveSession, which allows you to run operations without specifying a session. For non-interactive uses, it is more common to use tf.Session, and initialize as follows:

init_op = tf.initialize_all_variables()

sess = tf.Session()
sess.run(init_op)

filter(lambda x: x.n == 5, myList)

If you're not too worried in accuracy after days, you can simply do the maths

function timeSince(when) { // this ignores months
    var obj = {};
    obj._milliseconds = (new Date()).valueOf() - when.valueOf();
    obj.milliseconds = obj._milliseconds % 1000;
    obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
    obj.seconds = obj._seconds % 60;
    obj._minutes = (obj._seconds - obj.seconds) / 60;
    obj.minutes = obj._minutes % 60;
    obj._hours = (obj._minutes - obj.minutes) / 60;
    obj.hours = obj._hours % 24;
    obj._days = (obj._hours - obj.hours) / 24;
    obj.days = obj._days % 365;
    // finally
    obj.years = (obj._days - obj.days) / 365;
    return obj;
}

then timeSince(pastDate); and use the properties as you like.

Otherwise you can use .getUTC* to calculate it, but note it may be slightly slower to calculate

function timeSince(then) {
    var now = new Date(), obj = {};
    obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
    obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
    obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
    obj.hours = now.getUTCHours() - then.getUTCHours();
    obj.days = now.getUTCDate() - then.getUTCDate();
    obj.months = now.getUTCMonth() - then.getUTCMonth();
    obj.years = now.getUTCFullYear() - then.getUTCFullYear();
    // fix negatives
    if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
    if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
    if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
    if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
    if (obj.days < 0) { // months have different lengths
        --obj.months;
        now.setUTCMonth(now.getUTCMonth() + 1);
        now.setUTCDate(0);
        obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
    }
    if (obj.months < 0)  --obj.years, obj.months = (obj.months + 12) % 12;
    return obj;
}

To see both the normal distribution and your actual data you should plot your data as a histogram, then draw the probability density function over this. See the example on https://docs.scipy.org/doc/numpy-1.15.0/reference/generated/numpy.random.normal.html for exactly how to do this.

Look at jQuery Toggle

HTML:

<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>

jQuery:

jQuery(document).ready(function(){
    jQuery('#hideshow').live('click', function(event) {        
         jQuery('#content').toggle('show');
    });
});

For versions of jQuery 1.7 and newer use

jQuery(document).ready(function(){
    jQuery('#hideshow').on('click', function(event) {        
        jQuery('#content').toggle('show');
    });
});

For reference, kindly check this demo

Java 1.8 (as well as Groovy and Scala) has a thing called "Interface Defender Methods", which are interfaces with pre-defined default method bodies. By implementing multiple interfaces that use defender methods, you could effectively, in a way, extend the behavior of two interface objects.

Also, in Groovy, using the @Delegate annotation, you can extend behavior of two or more classes (with caveats when those classes contain methods of the same name). This code proves it:

class Photo {
    int width
    int height
}    
class Selection {
    @Delegate Photo photo    
    String title
    String caption
}    
def photo = new Photo(width: 640, height: 480)
def selection = new Selection(title: "Groovy", caption: "Groovy", photo: photo)
assert selection.title == "Groovy"
assert selection.caption == "Groovy"    
assert selection.width == 640
assert selection.height == 480

I used this:

HTMLDatetoIsoDate(htmlDate){
  let year = Number(htmlDate.toString().substring(0, 4))
  let month = Number(htmlDate.toString().substring(5, 7))
  let day = Number(htmlDate.toString().substring(8, 10))
  return new Date(year, month - 1, day)
}

isoDateToHtmlDate(isoDate){
  let date = new Date(isoDate);
  let dtString = ''
  let monthString = ''
  if (date.getDate() < 10) {
    dtString = '0' + date.getDate();
  } else {
    dtString = String(date.getDate())
  }
  if (date.getMonth()+1 < 10) {
    monthString = '0' + Number(date.getMonth()+1);
  } else {
    monthString = String(date.getMonth()+1);
  }
  return date.getFullYear()+'-' + monthString + '-'+dtString
}

I collaborated with one of my coworkers to start the PyRestTest framework for this reason: https://github.com/svanoort/pyresttest

Although you can work with the tests in Python, the normal test format is in YAML.

Sample test suite for a basic REST app -- verifies that APIs respond correctly, checking HTTP status codes, though you can make it examine response bodies as well:

New answer to old question

None of the existing answers to this old question address the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD. The fix is to use xs:simpleContent first. Details follow...

Your XML,

<price currency="euros">20000.00</price>

will be valid against either of the following corrected XSDs:

Locally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency">
            <xs:simpleType>
              <xs:restriction base="xs:string">
                <xs:enumeration value="pounds" />
                <xs:enumeration value="euros" />
                <xs:enumeration value="dollars" />
              </xs:restriction>
            </xs:simpleType>
          </xs:attribute>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Globally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType name="currencyType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="pounds" />
      <xs:enumeration value="euros" />
      <xs:enumeration value="dollars" />
    </xs:restriction>
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency" type="currencyType"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Notes

• As commented by @Paul, these do change the content type of price from xs:string to xs:decimal, but this is not strictly necessary and was not the real problem.
• As answered by @user998692, you could separate out the definition of currency, and you could change to xs:decimal, but this too was not the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD; xs:simpleContent is needed first.

A related matter (that wasn't asked but may have confused other answers):

How could price be restricted given that it has an attribute?

In this case, a separate, global definition of priceType would be needed; it is not possible to do this with only local type definitions.

How to restrict element content when element has attribute

      <xs:maxInclusive value="99999.99"/>  
    </xs:restriction>  
  </xs:simpleType>

  <xs:element name="price">

                <xs:enumeration value="dollars" />
              </xs:restriction>

Why would you want to do this?

IMHO you should store the date as default type and if needed fetch it transforming to desired format.

You could get away with specifying column's format but with a view. I don't know other methods.

Edited:

Seriously, in my opinion, you should create a view on that a table with date type. I'm talking about something like this:

create table sample_table ( id serial primary key, timestamp date); 

and than

create view v_example_table as select id, to_char(date, 'yyyymmmm');

And use v_example_table in your application.

The problem, as stated in your logs, is 2 dependencies trying to use different versions of 3rd dependency. Add one of the following to the app-gradle file:

androidTestCompile 'com.google.code.findbugs:jsr305:2.0.1'
androidTestCompile 'com.google.code.findbugs:jsr305:1.3.9'

Size of the boolean in java is virtual machine dependent. but Any Java object is aligned to an 8 bytes granularity. A Boolean has 8 bytes of header, plus 1 byte of payload, for a total of 9 bytes of information. The JVM then rounds it up to the next multiple of 8. so the one instance of java.lang.Boolean takes up 16 bytes of memory.

If you example class is instantiated on the stack, the contents of uninitialized scalar members is random and undefined.

For a global instance, uninitialized scalar members will be zeroed.

For members which are themselves instances of classes, their default constructors will be called, so your string object will get initialized.

• int *ptr; //uninitialized pointer (or zeroed if global)
• string name; //constructor called, initialized with empty string
• string *pname; //uninitialized pointer (or zeroed if global)
• string &rname; //compilation error if you fail to initialize this
• const string &crname; //compilation error if you fail to initialize this
• int age; //scalar value, uninitialized and random (or zeroed if global)

You would use a service for that in Angular. A service is a function you register with Angular, and that functions job is to return an object which will live until the browser is closed/refreshed. So it's a good place to store state in, and to synchronize that state with the server asynchronously as that state changes.

Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-).

The Java tutorial says:

Terminology: Nested classes are divided into two categories: static and non-static. Nested classes that are declared static are simply called static nested classes. Non-static nested classes are called inner classes.

In common parlance, the terms "nested" and "inner" are used interchangeably by most programmers, but I'll use the correct term "nested class" which covers both inner and static.

Classes can be nested ad infinitum, e.g. class A can contain class B which contains class C which contains class D, etc. However, more than one level of class nesting is rare, as it is generally bad design.

There are three reasons you might create a nested class:

• organization: sometimes it seems most sensible to sort a class into the namespace of another class, especially when it won't be used in any other context
• access: nested classes have special access to the variables/fields of their containing classes (precisely which variables/fields depends on the kind of nested class, whether inner or static).
• convenience: having to create a new file for every new type is bothersome, again, especially when the type will only be used in one context

There are four kinds of nested class in Java. In brief, they are:

• static class: declared as a static member of another class
• inner class: declared as an instance member of another class
• local inner class: declared inside an instance method of another class
• anonymous inner class: like a local inner class, but written as an expression which returns a one-off object

Let me elaborate in more details.

Static Classes

Static classes are the easiest kind to understand because they have nothing to do with instances of the containing class.

A static class is a class declared as a static member of another class. Just like other static members, such a class is really just a hanger on that uses the containing class as its namespace, e.g. the class Goat declared as a static member of class Rhino in the package pizza is known by the name pizza.Rhino.Goat.

package pizza;

public class Rhino {

    ...

    public static class Goat {
        ...
    }
}

Frankly, static classes are a pretty worthless feature because classes are already divided into namespaces by packages. The only real conceivable reason to create a static class is that such a class has access to its containing class's private static members, but I find this to be a pretty lame justification for the static class feature to exist.

Inner Classes

An inner class is a class declared as a non-static member of another class:

package pizza;

public class Rhino {

    public class Goat {
        ...
    }

    private void jerry() {
        Goat g = new Goat();
    }
}

Like with a static class, the inner class is known as qualified by its containing class name, pizza.Rhino.Goat, but inside the containing class, it can be known by its simple name. However, every instance of an inner class is tied to a particular instance of its containing class: above, the Goat created in jerry, is implicitly tied to the Rhino instance this in jerry. Otherwise, we make the associated Rhino instance explicit when we instantiate Goat:

Rhino rhino = new Rhino();
Rhino.Goat goat = rhino.new Goat();

(Notice you refer to the inner type as just Goat in the weird new syntax: Java infers the containing type from the rhino part. And, yes new rhino.Goat() would have made more sense to me too.)

So what does this gain us? Well, the inner class instance has access to the instance members of the containing class instance. These enclosing instance members are referred to inside the inner class via just their simple names, not via this (this in the inner class refers to the inner class instance, not the associated containing class instance):

public class Rhino {

    private String barry;

    public class Goat {
        public void colin() {
            System.out.println(barry);
        }
    }
}

In the inner class, you can refer to this of the containing class as Rhino.this, and you can use this to refer to its members, e.g. Rhino.this.barry.

Local Inner Classes

A local inner class is a class declared in the body of a method. Such a class is only known within its containing method, so it can only be instantiated and have its members accessed within its containing method. The gain is that a local inner class instance is tied to and can access the final local variables of its containing method. When the instance uses a final local of its containing method, the variable retains the value it held at the time of the instance's creation, even if the variable has gone out of scope (this is effectively Java's crude, limited version of closures).

Because a local inner class is neither the member of a class or package, it is not declared with an access level. (Be clear, however, that its own members have access levels like in a normal class.)

If a local inner class is declared in an instance method, an instantiation of the inner class is tied to the instance held by the containing method's this at the time of the instance's creation, and so the containing class's instance members are accessible like in an instance inner class. A local inner class is instantiated simply via its name, e.g. local inner class Cat is instantiated as new Cat(), not new this.Cat() as you might expect.

Anonymous Inner Classes

An anonymous inner class is a syntactically convenient way of writing a local inner class. Most commonly, a local inner class is instantiated at most just once each time its containing method is run. It would be nice, then, if we could combine the local inner class definition and its single instantiation into one convenient syntax form, and it would also be nice if we didn't have to think up a name for the class (the fewer unhelpful names your code contains, the better). An anonymous inner class allows both these things:

new *ParentClassName*(*constructorArgs*) {*members*}

This is an expression returning a new instance of an unnamed class which extends ParentClassName. You cannot supply your own constructor; rather, one is implicitly supplied which simply calls the super constructor, so the arguments supplied must fit the super constructor. (If the parent contains multiple constructors, the “simplest” one is called, “simplest” as determined by a rather complex set of rules not worth bothering to learn in detail--just pay attention to what NetBeans or Eclipse tell you.)

Alternatively, you can specify an interface to implement:

new *InterfaceName*() {*members*}

Such a declaration creates a new instance of an unnamed class which extends Object and implements InterfaceName. Again, you cannot supply your own constructor; in this case, Java implicitly supplies a no-arg, do-nothing constructor (so there will never be constructor arguments in this case).

Even though you can't give an anonymous inner class a constructor, you can still do any setup you want using an initializer block (a {} block placed outside any method).

Be clear that an anonymous inner class is simply a less flexible way of creating a local inner class with one instance. If you want a local inner class which implements multiple interfaces or which implements interfaces while extending some class other than Object or which specifies its own constructor, you're stuck creating a regular named local inner class.

To my opinion the best option to route to css & js use the following code:

<link rel="stylesheet" type="text/css" href="{{ URL::to('route/to/css') }}">

So if you have css file called main.css inside of css folder in public folder it should be the following:

<link rel="stylesheet" type="text/css" href="{{ URL::to('css/main.css') }}">

Place button widget in xml like below

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"
/>

After that initialise and handle on click listener in Activity like below ..

In Activity On Create method :

Button button =(Button) findViewById(R.id.button); 
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       Intent intent = new 
            Intent(CurrentActivity.this,DesiredActivity.class);
            startActivity(intent);
    }
});

Adding to @Dima's answer, if you're using maven to build your package, you can tell it to set your WAR file name to ROOT in pom.xml:

<build>
    <finalName>ROOT</finalName>
</build>

By default, tomcat will deploy ROOT.war webapp into root context (/).

An easy way to do this is using the pandas library like this.

import pandas as pd
fields = ['star_name', 'ra']

df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print df.keys()
# See content in 'star_name'
print df.star_name

The problem here was the skipinitialspace which remove the spaces in the header. So ' star_name' becomes 'star_name'

Here is an alternate way to add a custom separator line to a UITableView by making a CALayer for the image and using that as the separator line.

// make a CALayer for the image for the separator line

CALayer *separator = [CALayer layer];
separator.contents = (id)[UIImage imageNamed:@"myImage.png"].CGImage;
separator.frame = CGRectMake(0, 54, self.view.frame.size.width, 2);
[cell.layer addSublayer:separator];

You can determine it by checking if permission rationale is to be shown inside the onRequestPermissionsResult() callback method. And if you find any permission set to never ask again, you can request users to grant permissions from the settings.

My full implementation would be like below. It works for both single or multiple permissions requests. Use the following or directly use my library.

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if(permissions.length == 0){
        return;
    }
    boolean allPermissionsGranted = true;
    if(grantResults.length>0){
        for(int grantResult: grantResults){
            if(grantResult != PackageManager.PERMISSION_GRANTED){
                allPermissionsGranted = false;
                break;
            }
        }
    }
    if(!allPermissionsGranted){
        boolean somePermissionsForeverDenied = false;
        for(String permission: permissions){
            if(ActivityCompat.shouldShowRequestPermissionRationale(this, permission)){
                //denied
                Log.e("denied", permission);
            }else{
                if(ActivityCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED){
                    //allowed
                    Log.e("allowed", permission);
                } else{
                    //set to never ask again
                    Log.e("set to never ask again", permission);
                    somePermissionsForeverDenied = true;
                }
            }
        }
        if(somePermissionsForeverDenied){
            final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
            alertDialogBuilder.setTitle("Permissions Required")
                    .setMessage("You have forcefully denied some of the required permissions " +
                            "for this action. Please open settings, go to permissions and allow them.")
                    .setPositiveButton("Settings", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS,
                                    Uri.fromParts("package", getPackageName(), null));
                            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            startActivity(intent);
                        }
                    })
                    .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                        }
                    })
                    .setCancelable(false)
                    .create()
                    .show();
        }
    } else {
        switch (requestCode) {
            //act according to the request code used while requesting the permission(s).
        }
    }
}

You don't need the AND keyword. Here's the correct syntax of the UPDATE statement:

UPDATE 
    shop_category 
SET 
    name = 'Secolul XVI - XVIII', 
    name_eng = '16th to 18th centuries' 
WHERE 
    category_id = 4768

The following example will make it clear:

let contactJSON = '{"name":"John Doe","age":"11"}';
let contact = JSON.parse(contactJSON);
console.log(contact.name + ", " + contact.age);

// Output: John Doe, 11

Just put quotes around the Environment variable (as you have done) :
if "%DevEnvDir%" == "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\"
but it's the way you put opening bracket without a space that is confusing it.

Works for me...

C:\if "%gtk_basepath%" == "C:\Program Files\GtkSharp\2.12\" (echo yes)
yes

R.id.button is not part of R.layout.activity_main. How should the activity find it in the content view?

The layout that contains the button is displayed by the Fragment, so you have to get the Button there, in the Fragment.

In my case I made small changes, when i search the value in tabelview select (didSelectRowAtIndexPath) the cell its return the index of the cell so im get problem in move one viewControler to another.By using this method i found a solution to redirect to a new viewControler

let indexPath = tableView.indexPathForSelectedRow!
let currentCellValue = tableView.cellForRow(at: indexPath!)! as UITableViewCell
let textLabelText = currentCellValue.textLabel!.text
print(textLabelText) 

Look into using the ToString() method with a specified format.

Initially my repo said "Already up to date."

If I get your question correctly, you could do something like this.

>>> import matplotlib.pyplot as plt
>>> testList =[(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08),

 (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]
>>> from math import log

which would give you something like

Or as a line plot,

>>> plt.plot(*zip(*testList2))
>>> plt.show()

EDIT - If you want to add a title and labels for the axis, you could do something like

>>> plt.scatter(*zip(*testList2))
>>> plt.title('Random Figure')
>>> plt.xlabel('X-Axis')

I had a similar problem and in my case, the issue was different (I am using Django templates).

The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.

I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.

For those who don't want to remember the syntax everytime here is a simple encapsulation:

public class FileDialogFilter : List<string>
{
    public string Explanation { get; }

    public FileDialogFilter(string explanation, params string[] extensions)
    {
        Explanation = explanation;
        AddRange(extensions);
    }

    public string GetFileDialogRepresentation()
    {
        if (!this.Any())
        {
            throw new ArgumentException("No file extension is defined.");
        }

        StringBuilder builder = new StringBuilder();

        builder.Append(Explanation);

        builder.Append(" (");
        builder.Append(String.Join(", ", this));
        builder.Append(")");

        builder.Append("|");
        builder.Append(String.Join(";", this));

        return builder.ToString();
    }
}

public class FileDialogFilterCollection : List<FileDialogFilter>
{
    public string GetFileDialogRepresentation()
    {
        return String.Join("|", this.Select(filter => filter.GetFileDialogRepresentation()));
    }
}

Usage:

FileDialogFilter filterImage = new FileDialogFilter("Image Files", "*.jpeg", "*.bmp");
FileDialogFilter filterOffice = new FileDialogFilter("Office Files", "*.doc", "*.xls", "*.ppt");

FileDialogFilterCollection filters = new FileDialogFilterCollection
{
    filterImage,
    filterOffice
};

OpenFileDialog fileDialog = new OpenFileDialog
{
    Filter = filters.GetFileDialogRepresentation()
};

fileDialog.ShowDialog();

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
    INNER JOIN server2.database.dbo.server2table ON .....

use split

Split a file into fixed-size pieces, creates output files containing consecutive sections of INPUT (standard input if none is given or INPUT is `-')

Syntax split [options] [INPUT [PREFIX]]

If jar file is like executable spring boot jar file then scope of all dependencies must be compile to include all jar files.

But if jar file used in other packages or applications then it does not need to include all dependencies in jar file because these packages or applications can provide other dependencies themselves.

I've a PHP library which helps to insert array into MySQL Database. By using this you can create update and delete. Your array key value should be same as the table column value. Just using a single line code for the create operation

DB::create($db, 'YOUR_TABLE_NAME', $dataArray);

where $db is your Database connection.

Similarly, You can use this for update and delete. Select operation will be available soon. Github link to download : https://github.com/pairavanvvl/crud

Restarting the Visual Studio worked for me. Also try restarting Visual Studio normally (Not Run as Administrator). Try Restarting the System and repeat above step.

Update: React 16.0 introduced portals through ReactDOM.createPortal link

Update: next versions of React (Fiber: probably 16 or 17) will include a method to create portals: ReactDOM.unstable_createPortal() link

Use portals

Dan Abramov answer first part is fine, but involves a lot of boilerplate. As he said, you can also use portals. I'll expand a bit on that idea.

The advantage of a portal is that the popup and the button remain very close into the React tree, with very simple parent/child communication using props: you can easily handle async actions with portals, or let the parent customize the portal.

What is a portal?

A portal permits you to render directly inside document.body an element that is deeply nested in your React tree.

The idea is that for example you render into body the following React tree:

<div className="layout">
  <div className="outside-portal">
    <Portal>
      <div className="inside-portal">
        PortalContent
      </div>
    </Portal>
  </div>
</div>

And you get as output:

<body>
  <div class="layout">
    <div class="outside-portal">
    </div>
  </div>
  <div class="inside-portal">
    PortalContent
  </div>
</body>

The inside-portal node has been translated inside <body>, instead of its normal, deeply-nested place.

When to use a portal

A portal is particularly helpful for displaying elements that should go on top of your existing React components: popups, dropdowns, suggestions, hotspots

Why use a portal

No z-index problems anymore: a portal permits you to render to <body>. If you want to display a popup or dropdown, this is a really nice idea if you don't want to have to fight against z-index problems. The portal elements get added do document.body in mount order, which means that unless you play with z-index, the default behavior will be to stack portals on top of each others, in mounting order. In practice, it means that you can safely open a popup from inside another popup, and be sure that the 2nd popup will be displayed on top of the first, without having to even think about z-index.

In practice

Most simple: use local React state: if you think, for a simple delete confirmation popup, it's not worth to have the Redux boilerplate, then you can use a portal and it greatly simplifies your code. For such a use case, where the interaction is very local and is actually quite an implementation detail, do you really care about hot-reloading, time-traveling, action logging and all the benefits Redux brings you? Personally, I don't and use local state in this case. The code becomes as simple as:

class DeleteButton extends React.Component {
  static propTypes = {
    onDelete: PropTypes.func.isRequired,
  };

  state = { confirmationPopup: false };

  open = () => {
    this.setState({ confirmationPopup: true });
  };

  close = () => {
    this.setState({ confirmationPopup: false });
  };

  render() {
    return (
      <div className="delete-button">
        <div onClick={() => this.open()}>Delete</div>
        {this.state.confirmationPopup && (
          <Portal>
            <DeleteConfirmationPopup
              onCancel={() => this.close()}
              onConfirm={() => {
                this.close();
                this.props.onDelete();
              }}
            />
          </Portal>
        )}
      </div>
    );
  }
}

Simple: you can still use Redux state: if you really want to, you can still use connect to choose whether or not the DeleteConfirmationPopup is shown or not. As the portal remains deeply nested in your React tree, it is very simple to customize the behavior of this portal because your parent can pass props to the portal. If you don't use portals, you usually have to render your popups at the top of your React tree for z-index reasons, and usually have to think about things like "how do I customize the generic DeleteConfirmationPopup I built according to the use case". And usually you'll find quite hacky solutions to this problem, like dispatching an action that contains nested confirm/cancel actions, a translation bundle key, or even worse, a render function (or something else unserializable). You don't have to do that with portals, and can just pass regular props, since DeleteConfirmationPopup is just a child of the DeleteButton

Conclusion

Portals are very useful to simplify your code. I couldn't do without them anymore.

Note that portal implementations can also help you with other useful features like:

• Accessibility
• Espace shortcuts to close the portal
• Handle outside click (close portal or not)
• Handle link click (close portal or not)
• React Context made available in portal tree

react-portal or react-modal are nice for popups, modals, and overlays that should be full-screen, generally centered in the middle of the screen.

react-tether is unknown to most React developers, yet it's one of the most useful tools you can find out there. Tether permits you to create portals, but will position automatically the portal, relative to a given target. This is perfect for tooltips, dropdowns, hotspots, helpboxes... If you have ever had any problem with position absolute/relative and z-index, or your dropdown going outside of your viewport, Tether will solve all that for you.

You can, for example, easily implement onboarding hotspots, that expands to a tooltip once clicked:

Real production code here. Can't be any simpler :)

<MenuHotspots.contacts>
  <ContactButton/>
</MenuHotspots.contacts>

Edit: just discovered react-gateway which permits to render portals into the node of your choice (not necessarily body)

Edit: it seems react-popper can be a decent alternative to react-tether. PopperJS is a library that only computes an appropriate position for an element, without touching the DOM directly, letting the user choose where and when he wants to put the DOM node, while Tether appends directly to the body.

Edit: there's also react-slot-fill which is interesting and can help solve similar problems by allowing to render an element to a reserved element slot that you put anywhere you want in your tree

STATICFILES_DIRS: You can keep the static files for your project here e.g. the ones used by your templates.

STATIC_ROOT: leave this empty, when you do manage.py collectstatic, it will search for all the static files on your system and move them here. Your static file server is supposed to be mapped to this folder wherever it is located. Check it after running collectstatic and you'll find the directory structure django has built.

--------Edit----------------

As pointed out by @DarkCygnus, STATIC_ROOT should point at a directory on your filesystem, the folder should be empty since it will be populated by Django.

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

or

STATIC_ROOT = '/opt/web/project/static_files'

--------End Edit -----------------

STATIC_URL: '/static/' is usually fine, it's just a prefix for static files.

The answers above are still using the old Python 3.4 style coroutines. Here is what you would write if you got Python 3.5+.

aiohttp supports http proxy now

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
            'http://python.org',
            'https://google.com',
            'http://yifei.me'
        ]
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:
            print(html[:100])

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Pass a returnUrl parameter (url encoded) to the change and login actions and inside redirect to this given returnUrl. Your login action might look something like this:

public ActionResult Login(string returnUrl) 
{
    // Do something...
    return Redirect(returnUrl);
}

Improving the first answer just get rid of the padding and add line-height and vertical-align:

.numberCircle {
   border-radius: 50%;       

   width: 36px;
   height: 36px;
   line-height: 36px;
   vertical-align:middle;

   background: #fff;
   border: 2px solid #666;
   color: #666;

   text-align: center;
   font: 32px Arial, sans-serif;
}

If you're pointing the config at a domain (eg fabrikam.com), do an NSLOOKUP to ensure all the responding IPs are valid, and can be connected to on port 389:

NSLOOKUP fabrikam.com

Test-NetConnection <IP returned from NSLOOKUP> -port 389

Here is the answer for those of you looking like I did all over the web trying to find out how to do this task. Uploading a photo to a server with the file name stored in a mysql database and other form data you want in your Database. Please let me know if it helped.

Firstly the form you need:

    <form method="post" action="addMember.php" enctype="multipart/form-data">
    <p>
              Please Enter the Band Members Name.
            </p>
            <p>
              Band Member or Affiliates Name:
            </p>
            <input type="text" name="nameMember"/>
            <p>
              Please Enter the Band Members Position. Example:Drums.
            </p>
            <p>
              Band Position:
            </p>
            <input type="text" name="bandMember"/>
            <p>
              Please Upload a Photo of the Member in gif or jpeg format. The file name should be named after the Members name. If the same file name is uploaded twice it will be overwritten! Maxium size of File is 35kb.
            </p>
            <p>
              Photo:
            </p>
            <input type="hidden" name="size" value="350000">
            <input type="file" name="photo"> 
            <p>
              Please Enter any other information about the band member here.
            </p>
            <p>
              Other Member Information:
            </p>
<textarea rows="10" cols="35" name="aboutMember">
</textarea>
            <p>
              Please Enter any other Bands the Member has been in.
            </p>
            <p>
              Other Bands:
            </p>
            <input type="text" name="otherBands" size=30 />
            <br/>
            <br/>
            <input TYPE="submit" name="upload" title="Add data to the Database" value="Add Member"/>
          </form>

Then this code processes you data from the form:

   <?php

// This is the directory where images will be saved
$target = "your directory";
$target = $target . basename( $_FILES['photo']['name']);

// This gets all the other information from the form
$name=$_POST['nameMember'];
$bandMember=$_POST['bandMember'];
$pic=($_FILES['photo']['name']);
$about=$_POST['aboutMember'];
$bands=$_POST['otherBands'];


// Connects to your Database
mysqli_connect("yourhost", "username", "password") or die(mysqli_error()) ;
mysqli_select_db("dbName") or die(mysqli_error()) ;

// Writes the information to the database
mysqli_query("INSERT INTO tableName (nameMember,bandMember,photo,aboutMember,otherBands)
VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;

// Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{

// Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {

// Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

Swift 4

enum ImageFormat {
    case png
    case jpeg(CGFloat)
}

extension UIImage {
    func base64(format: ImageFormat) -> String? {
        var imageData: Data?

        switch format {
        case .png: imageData = UIImagePNGRepresentation(self)
        case .jpeg(let compression): imageData = UIImageJPEGRepresentation(self, compression)
        }

        return imageData?.base64EncodedString()
    }
}

extension String {
    func imageFromBase64() -> UIImage? {
        guard let data = Data(base64Encoded: self) else { return nil }

        return UIImage(data: data)
    }
}

final: final is a keyword. The variable decleared as final should be initialized only once and cannot be changed. Java classes declared as final cannot be extended. Methods declared as final cannot be overridden.

finally: finally is a block. The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is useful for more than just exception handling - it allows the programmer to avoid having cleanup code accidentally bypassed by a return, continue, or break. Putting cleanup code in a finally block is always a good practice, even when no exceptions are anticipated.

finalize: finalize is a method. Before an object is garbage collected, the runtime system calls its finalize() method. You can write system resources release code in finalize() method before getting garbage collected.

You can't change a DateTime value - it's immutable. However, you can change the variable to have a new value. The easiest way of doing that to change just the time is to create a TimeSpan with the relevant time, and use the DateTime.Date property:

DateTime s = ...;
TimeSpan ts = new TimeSpan(10, 30, 0);
s = s.Date + ts;

s will now be the same date, but at 10.30am.

Note that DateTime disregards daylight saving time transitions, representing "naive" Gregorian time in both directions (see Remarks section in the DateTime docs). The only exceptions are .Now and .Today: they retrieve current system time which reflects these events as they occur.

This is the kind of thing which motivated me to start the Noda Time project, which is now production-ready. Its ZonedDateTime type is made "aware" by linking it to a tz database entry.

This is what worked for me.

<!DOCTYPE html> 
<form action="desired Link">
  <button>  <img src="desired image URL"/>
  </button>
</form>
<style> 

</style>

Open tmux configuration file with the following command:

vim ~/.tmux.conf

In the configuration file add the following line:

set -g history-limit 5000

Log out and log in again, start a new tmux windows and your limit is 5000 now.

Place a breakpoint on the ending brace of main(). It will get tripped even with multiple return statements. The only downside is that a call to exit() won't be caught.

If you're not debugging, follow the advice in Zoidberg's answer and start your program with Ctrl+F5 instead of just F5.

If you already have your parameters set like $_POST['eg'] for example and you don't wish to change it, simply do it like this:

$_POST = json_decode(file_get_contents('php://input'), true);

This will save you the hassle of changing all $_POST to something else and allow you to still make normal post requests if you wish to take this line out.

String dateStart = "01/14/2015 08:29:58";
String dateStop = "01/15/2015 11:31:48";

//HH converts hour in 24 hours format (0-23), day calculation
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");

Date d1 = null;
Date d2 = null;

d1 = format.parse(dateStart);
d2 = format.parse(dateStop);

//in milliseconds
long diff = d2.getTime() - d1.getTime();

long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);

System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");

sp_lock

When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:

SELECT object_name(16003073)

EDIT :

There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/

If you want to do it on your local machine instead of in the context of SQL server then I would use the following. It is what we use at my company.

$ServerName = "_ServerName_"
$DatabaseName = "_DatabaseName_"
$Query = "SELECT * FROM Table WHERE Column = ''"

#Timeout parameters
$QueryTimeout = 120
$ConnectionTimeout = 30

#Action of connecting to the Database and executing the query and returning results if there were any.
$conn=New-Object System.Data.SqlClient.SQLConnection
$ConnectionString = "Server={0};Database={1};Integrated Security=True;Connect Timeout={2}" -f $ServerName,$DatabaseName,$ConnectionTimeout
$conn.ConnectionString=$ConnectionString
$conn.Open()
$cmd=New-Object system.Data.SqlClient.SqlCommand($Query,$conn)
$cmd.CommandTimeout=$QueryTimeout
$ds=New-Object system.Data.DataSet
$da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
[void]$da.fill($ds)
$conn.Close()
$ds.Tables

Just fill in the $ServerName, $DatabaseName and the $Query variables and you should be good to go.

I am not sure how we originally found this out, but there is something very similar here.

In Swift 3 and later you can:

let url = URL(string: "http://www.thisismylink.com/postName.php")!
var request = URLRequest(url: url)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
let parameters: [String: Any] = [
    "id": 13,
    "name": "Jack & Jill"
]
request.httpBody = parameters.percentEncoded()

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, 
        let response = response as? HTTPURLResponse, 
        error == nil else {                                              // check for fundamental networking error
        print("error", error ?? "Unknown error")
        return
    }

    guard (200 ... 299) ~= response.statusCode else {                    // check for http errors
        print("statusCode should be 2xx, but is \(response.statusCode)")
        print("response = \(response)")
        return
    }

    let responseString = String(data: data, encoding: .utf8)
    print("responseString = \(responseString)")
}

task.resume()

Where:

extension Dictionary {
    func percentEncoded() -> Data? {
        return map { key, value in
            let escapedKey = "\(key)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
            let escapedValue = "\(value)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
            return escapedKey + "=" + escapedValue
        }
        .joined(separator: "&")
        .data(using: .utf8)
    }
}

extension CharacterSet { 
    static let urlQueryValueAllowed: CharacterSet = {
        let generalDelimitersToEncode = ":#[]@" // does not include "?" or "/" due to RFC 3986 - Section 3.4
        let subDelimitersToEncode = "!$&'()*+,;="

        var allowed = CharacterSet.urlQueryAllowed
        allowed.remove(charactersIn: "\(generalDelimitersToEncode)\(subDelimitersToEncode)")
        return allowed
    }()
}

This checks for both fundamental networking errors as well as high-level HTTP errors. This also properly percent escapes the parameters of the query.

Note, I used a name of Jack & Jill, to illustrate the proper x-www-form-urlencoded result of name=Jack%20%26%20Jill, which is “percent encoded” (i.e. the space is replaced with %20 and the & in the value is replaced with %26).

See previous revision of this answer for Swift 2 rendition.

Method 1: Download ojdbc.jar

add ojdbc6.jar to deployment assembly. Right click on project->properties->select deployment assembly->click on 'Add' ->select 'Archives from File System'->browse to the folder where ojdbc6.jar is saved.->add the jar->click finish->Apply/OK.

Method 2:

if you want to add ojdbc.jar to your maven dependencies you follow this link: http://www.mkyong.com/maven/how-to-add-oracle-jdbc-driver-in-your-maven-local-repository/ . . Even if you're using a maven project it is not necessary to add ojdbc to maven dependencies(method 2), method 1 (adding directly to deployment assembly) works just fine.

I know it's been a while, but I thought i would update the answer since there are new (faster and simpler) ways to solve this problem. Since ECMAscript 5.1 yo can use the isArray() method avaiable in the Array class.

Yo can see it's documentation in MDN here.

I think you shouldn't have a compatibility problem nowadays, but just in case, if you add this to your code you should be always safe that Array.isArray() is polyfilled:

if (!Array.isArray) {
  Array.isArray = function(arg) {
    return Object.prototype.toString.call(arg) === '[object Array]';
  };
}

Another way for the default sound

builder.setDefaults(Notification.DEFAULT_SOUND);

I had a similar error but for me it was react-router. Solved it by installing types for it.

npm install --save @types/react-router

Error:

(6,30): error TS7016: Could not find a declaration file for module 'react-router'. '\node_modules\react-router\index.js' implicitly has an 'any' type.

If you would like to disable it site wide you can instead edit tsconfig.json and set noImplicitAny to false.

xcopy src dest /I

REM This assumes dest is a folder and will create it, if it doesnt exists

For testing on both laptops on the same wireless and across the internet you could use a service like http://localhost.run/ or https://ngrok.com/

I found that the hostname was not visible to other containers when using docker run. This turns out to be a known issue (perhaps more a known feature), with part of the discussion being:

We should probably add a warning to the docs about using hostname. I think it is rarely useful.

The correct way of assigning a hostname - in terms of container networking - is to define an alias like so:

services:
  some-service:
    networks:
      some-network:
        aliases:
          - alias1
          - alias2

Unfortunately this still doesn't work with docker run. The workaround is to assign the container a name:

docker-compose run --name alias1 some-service

And alias1 can then be pinged from the other containers.

UPDATE: As @grilix points out, you should use docker-compose run --use-aliases to make the defined aliases available.

The is related to the ini configuration setting allow_url_fopen.

You should be aware that enable that option may make some bugs in your code exploitable.

For instance, this failure to validate input may turn into a full-fledged remote code execution vulnerability:

copy($_GET["file"], "."); 

You probably want something like this overload of String.Join:

String.Join<T> Method (String, IEnumerable<T>)

Docs:

http://msdn.microsoft.com/en-us/library/dd992421.aspx

In your example, you'd use

String.Join("", Client);

In looking at the "Web Forms : input placeholder" section of HTML5 Cross Browser Polyfills, one I saw was jQuery-html5-placeholder.

I tried the demo out with IE9, and it looks like it wraps your <input> with a span and overlays a label with the placeholder text.

<label>Text:
  <span style="position: relative;">
    <input id="placeholder1314588474481" name="text" maxLength="6" type="text" placeholder="Hi Mom">
    <label style="font: 0.75em/normal sans-serif; left: 5px; top: 3px; width: 147px; height: 15px; color: rgb(186, 186, 186); position: absolute; overflow-x: hidden; font-size-adjust: none; font-stretch: normal;" for="placeholder1314588474481">Hi Mom</label>
  </span>
</label>

There are also other shims there, but I didn't look at them all. One of them, Placeholders.js, advertises itself as "No dependencies (so no need to include jQuery, unlike most placeholder polyfill scripts)."

Edit: For those more interested in "how" that "what", How to create an advanced HTML5 placeholder polyfill which walks through the process of creating a jQuery plugin that does this.

Also, see keep placeholder on focus in IE10 for comments on how placeholder text disappears on focus with IE10, which differs from Firefox and Chrome. Not sure if there is a solution for this problem.

I have provide two methods for doing so for minutes as well as for years and hours if you want to see more examples:

import datetime
print(datetime.datetime.now())
print(datetime.datetime.now() - datetime.timedelta(minutes = 15))
print(datetime.datetime.now() + datetime.timedelta(minutes = -15))
print(datetime.timedelta(hours = 5))
print(datetime.datetime.now() + datetime.timedelta(days = 3))
print(datetime.datetime.now() + datetime.timedelta(days = -9))
print(datetime.datetime.now() - datetime.timedelta(days = 9))

I get the following results:

2016-06-03 16:04:03.706615
2016-06-03 15:49:03.706622
2016-06-03 15:49:03.706642
5:00:00
2016-06-06 16:04:03.706665
2016-05-25 16:04:03.706676
2016-05-25 16:04:03.706687
2016-06-03
16:04:03.706716

This is the method that I would use.

DECLARE 
    @DateFrom DATETIME = GETDATE(),
    @DateTo DATETIME = DATEADD(HOUR, -1, GETDATE() + 2); -- Add 2 days and minus one hour


-- Dates spaced a day apart 

WITH MyDates (MyDate)
AS (
    SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(DAY, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
    , CONVERT(DATE, MyDates.MyDate) AS [MyDate in DATE format]
FROM 
    MyDates;

Here is a similar example, but this time the dates are spaced one hour apart to further aid understanding of how the query works:

-- Alternative example with dates spaced an hour apart

WITH MyDates (MyDate)
AS (SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(HOUR, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
FROM 
    MyDates;

As you can see, the query is fast, accurate and versatile.

Here is a complete sample:

I'm missing the translation call tr in the answers.

One of the simplest solutions, which allows for later internationalization:

if (QMessageBox::Yes == QMessageBox::question(this,
                                              tr("title"),
                                              tr("Message/Question")))
{
    // do stuff
}

It is generally a good Qt habit to put code-level Strings within a tr("Your String") call.

(QMessagebox as above works within any QWidget method)

EDIT:

you can use QMesssageBox outside a QWidget context, see @TobySpeight's answer.

If you're even outside a QObject context, replace tr with qApp->translate("context", "String") - you'll need to #include <QApplication>

The Kotlin way by using builtin Extension function on File

Write: yourFile.writeText(textFromEditText)
Read: yourFile.readText()

As already mentioned in the answer by robertc, Chrome blocks certain functionality, like the geo location with local files. An easier alternative to setting up an own web server would be to just start Chrome with the parameter --allow-file-access-from-files. Then you can use the geo location, provided you didn't turn it off in your settings.

Any one can try this command to truncate any file in linux system

This will surely work in any format :

truncate -s 0 file.txt

use "path" for windows else it gives the error as: positional arguments not allowed

You can use the SYS_GUID() function to generate a GUID in your insert statement:

insert into mytable (guid_col, data) values (sys_guid(), 'xxx');

The preferred datatype for storing GUIDs is RAW(16).

As Gopinath answer:

 select sys_guid() from dual
 union all
 select sys_guid() from dual
 union all 
 select sys_guid() from dual

You get

88FDC68C75DDF955E040449808B55601
88FDC68C75DEF955E040449808B55601
88FDC68C75DFF955E040449808B55601

As Tony Andrews says, differs only at one character

88FDC68C75DDF955E040449808B55601
88FDC68C75DEF955E040449808B55601

I hope these answers are little bit old, just change the input type in resource layout file will solve your problem. For example:

<EditText
        android:id="@+id/notesInput"
        android:hint="Notes"
        android:inputType="textMultiLine"
/>

Using Java 8

With Java 8 you can simply convert your list to a stream allowing you to write:

import java.util.List;
import java.util.stream.Collectors;

List<Sample> list = new ArrayList<Sample>();
List<Sample> result = list.stream()
    .filter(a -> Objects.equals(a.value3, "three"))
    .collect(Collectors.toList());

Note that

• a -> Objects.equals(a.value3, "three") is a lambda expression
• result is a List with a Sample type
• It's very fast, no cast at every iteration
• If your filter logic gets heavier, you can do list.parallelStream() instead of list.stream() (read this)

Apache Commons

If you can't use Java 8, you can use Apache Commons library and write:

import org.apache.commons.collections.CollectionUtils;
import org.apache.commons.collections.Predicate;

Collection result = CollectionUtils.select(list, new Predicate() {
     public boolean evaluate(Object a) {
         return Objects.equals(((Sample) a).value3, "three");
     }
 });

// If you need the results as a typed array:
Sample[] resultTyped = (Sample[]) result.toArray(new Sample[result.size()]);

Note that:

• There is a cast from Object to Sample at each iteration
• If you need your results to be typed as Sample[], you need extra code (as shown in my sample)

Bonus: A nice blog article talking about how to find element in list.

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

The awnser of @Alireza is totally correct, but you must notice that when using this code

var res = from element in list
          group element by element.F1
              into groups
              select groups.OrderBy(p => p.F2).First();

which is simillar to this code because you ordering the list and then do the grouping so you are getting the first row of groups

var res = (from element in list)
          .OrderBy(x => x.F2)
          .GroupBy(x => x.F1)
          .Select()

Now if you want to do something more complex like take the same grouping result but take the first element of F2 and the last element of F3 or something more custom you can do it by studing the code bellow

 var res = (from element in list)
          .GroupBy(x => x.F1)
          .Select(y => new
           {
             F1 = y.FirstOrDefault().F1;
             F2 = y.First().F2;
             F3 = y.Last().F3;
           });

So you will get something like

   F1            F2             F3 
 -----------------------------------
   Nima          1990           12
   John          2001           2
   Sara          2010           4

Use this. Works fine

input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
input.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

EDIT

kotlin version

fun EditText.onlyNumbers() {
    inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL or
        InputType.TYPE_NUMBER_FLAG_SIGNED
    keyListener = DigitsKeyListener.getInstance("0123456789")
}

try like this

vars_prompt:
 - name: "user_password"    
   prompt: "Enter a password for the user"    
   private: yes    
   encrypt: "md5_crypt" #need to have python-passlib installed in local machine before we can use it    
   confirm: yes    
   salt_size: 7

 - name: "add new user" user: name="{{user_name}}" comment="{{description_user}}" password="{{user_password}}" home="{{home_dir}}" shell="/bin/bash"

This is not a direct answer, but very useful if you don't have access to how java starts: you can set the environment variable JAVA_TOOLS_OPTIONS to -Dfile.encoding="UTF-8" and every time the jvm starts it will pick up that option.

Expanding on @Kiran's answer, which I agree is more succinct and Pythonic, this adds codecs to support the reading and writing of UTF-8:

import codecs 

from tempfile import mkstemp
from shutil import move
from os import remove


def replace(source_file_path, pattern, substring):
    fh, target_file_path = mkstemp()

    with codecs.open(target_file_path, 'w', 'utf-8') as target_file:
        with codecs.open(source_file_path, 'r', 'utf-8') as source_file:
            for line in source_file:
                target_file.write(line.replace(pattern, substring))
    remove(source_file_path)
    move(target_file_path, source_file_path)

If you want to add html content to your email, url encode your html code for the message body and include it in your mailto link code, but trouble is you can't set the type of the email from this link from plaintext to html, the client using the link needs their mail client to send html emails by default. In case you want to test here is the code for a simple mailto link, with an image wrapped in a link (angular style urls added for visibility):

<a href="mailto:?body=%3Ca%20href%3D%22{{ scope.url }}%22%3E%3Cimg%20src%3D%22{{ scope.url }}%22%20width%3D%22300%22%20%2F%3E%3C%2Fa%3E">

The html tags are url encoded.

There is no way to do so, as JavaScript does not have an access to computer name, file system and other local info. Security is the main purpose.

By using pandas we can read excel easily.

import pandas as pd 
from pandas import ExcelWriter
from pandas import ExcelFile 

DataF=pd.read_excel("Test.xlsx",sheet_name='Sheet1')

print("Column headings:")
print(DataF.columns)

If you use anaconda navigator on windows, you can go too enviornments and scroll over the enviornments, the root enviorment will indicate where it is installed. It can help if you want to use this enviorment when you need to connect this to other applications, where you want to integrate some python code.

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

In addition to Dee Jee solution, After trying out his solution, My error never went.

I noticed(after two days of head scratch) that the browser has cached the files improperly.

• My browser wasn't able to load the preview of the cached files and status code from express was 301.
• In the networks tab of the browser dev tools, I get that those files are server from disk cache.

Solution

Remove the cached files. By clearing the browser history in a span of 1 hour, so that all the cached files get deleted.

Every time you start a session (applies to PHP version 5.2.54), session_start() creates a new session id.

Here is the fix that worked for me.

File1.php

session_id('mySessionID'); //SET id first before calling  session start
session_start();

$name = "Nitin Hurkadli";
$_SESSION['username'] = $name;

File2.php

session_id('mySessionID'); 
session_start();

$name = $_SESSION['username'];
echo "Hello  " . $name;

Following @armod's update about exceptions being added right on client objects. I'll show how you can see all exceptions defined for your client class.

Exceptions are generated dynamically when you create your client with session.create_client() or boto3.client(). Internally it calls method botocore.errorfactory.ClientExceptionsFactory._create_client_exceptions() and fills client.exceptions field with constructed exception classes.

All class names are available in client.exceptions._code_to_exception dictionary, so you can list all types with following snippet:

client = boto3.client('s3')

for ex_code in client.exceptions._code_to_exception:
    print(ex_code)

Hope it helps.

To start:

Pros:

• It is the unique way of implementing a variable number of nested loops (and the only elegant way of implementing a big constant number of nested loops).

Cons:

• Recursive methods will often throw a StackOverflowException when processing big sets. Recursive loops don't have this problem though.

Note: If you have broad knowledge already about rebase then use below one liner for fast rebase. Solution: Assuming you are on your working branch and you are the only person working on it.

git fetch && git rebase origin/master

Resolve any conflicts, test your code, commit and push new changes to remote branch.

                            ~:   For noobs   :~

The following steps might help anyone who are new to git rebase and wanted to do it without hassle

Step 1: Assuming that there are no commits and changes to be made on YourBranch at this point. We are visiting YourBranch.

git checkout YourBranch
git pull --rebase

What happened? Pulls all changes made by other developers working on your branch and rebases your changes on top of it.

Step 2: Resolve any conflicts that presents.

Step 3:

git checkout master
git pull --rebase

What happened? Pulls all the latest changes from remote master and rebases local master on remote master. I always keep remote master clean and release ready! And, prefer only to work on master or branches locally. I recommend in doing this until you gets a hand on git changes or commits. Note: This step is not needed if you are not maintaining local master, instead you can do a fetch and rebase remote master directly on local branch directly. As I mentioned in single step in the start.

Step 4: Resolve any conflicts that presents.

Step 5:

git checkout YourBranch
git rebase master

What happened? Rebase on master happens

Step 6: Resolve any conflicts, if there are conflicts. Use git rebase --continue to continue rebase after adding the resolved conflicts. At any time you can use git rebase --abort to abort the rebase.

Step 7:

git push --force-with-lease 

What happened? Pushing changes to your remote YourBranch. --force-with-lease will make sure whether there are any other incoming changes for YourBranch from other developers while you rebasing. This is super useful rather than force push. In case any incoming changes then fetch them to update your local YourBranch before pushing changes.

Why do I need to push changes? To rewrite the commit message in remote YourBranch after proper rebase or If there are any conflicts resolved? Then you need to push the changes you resolved in local repo to the remote repo of YourBranch

Yahoooo...! You are succesfully done with rebasing.

You might also be looking into doing:

git checkout master
git merge YourBranch

When and Why? Merge your branch into master if done with changes by you and other co-developers. Which makes YourBranch up-to-date with master when you wanted to work on same branch later.

                            ~:   (?o 3 o)? rebase   :~

Spring boot will look for datasoure properties in application.properties file.

Please define it in application.properties or yml file

application.properties

spring.datasource.url=xxx
spring.datasource.username=xxx
spring.datasource.password=xxx
spring.datasource.driver-class-name=xxx

If you need your own configuration you could set your own profile and use the datasource values while bean creation.

You are comparing two objects for equality. The snippet:

if (obj == this) {     return true; } 

is a quick test that can be read

"If the object I'm comparing myself to is me, return true"

. You usually see this happen in equals methods so they can exit early and avoid other costly comparisons.

You can look in sys.types or use TYPE_ID:

IF TYPE_ID(N'MyType') IS NULL ...

Just a precaution: using type_id won't verify that the type is a table type--just that a type by that name exists. Otherwise gbn's query is probably better.

EventHandler.GetInvocationList().Length > 0

Try this:

import os
import sys

for root, subdirs, files in os.walk(path):

    for file in os.listdir(root):

        filePath = os.path.join(root, file)

        if os.path.isdir(filePath):
            pass

        else:
            f = open (filePath, 'r')
            # Do Stuff

You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:

public class ArrayUtils {
    public static <T> E[] appendToArray(E[] array, E item) {
        E[] result = (E[])new Object[array.length+1];
        result[array.length] = item;
        return result;
    }
}

That's because, it gets returned after validateView();;

Use this:

OnClientClick="var ret = validateView();ShowDiv1(); return ret;"

Given the interface:

public interface IAnything {
  int i;
  void m1();
  void m2();
  void m3();
}

This is how Java actually sees it:

public interface IAnything {
  public static final int i;
  public abstract void m1();
  public abstract void m2();
  public abstract void m3();
}

So you can leave some (or all) of these abstract methods unimplemented, just as you would do in the case of abstract classes extending another abstract class.

When you implement an interface, the rule that all interface methods must be implemented in the derived class, applies only to concrete class implementation (i.e., which isn't abstract itself).

If you indeed plan on creating an abstract class out of it, then there is no rule that says you've to implement all the interface methods (note that in such a case it is mandatory to declare the derived class as abstract)

jQuery.offset needs to be combined with scrollTop and scrollLeft as shown in this diagram:

  var $window = $(window),_x000D_
    scrollLeft = $window.scrollLeft(),_x000D_
    scrollTop = $window.scrollTop(),_x000D_
    offset = $e.offset(),_x000D_
    rect1 = { x1: scrollLeft, y1: scrollTop, x2: scrollLeft + $window.width(), y2: scrollTop + $window.height() },_x000D_
    rect2 = { x1: offset.left, y1: offset.top, x2: offset.left + $e.width(), y2: offset.top + $e.height() };_x000D_
  return {_x000D_
    left: offset.left - scrollLeft,_x000D_
    top: offset.top - scrollTop,_x000D_
    insideViewport: rect1.x1 < rect2.x2 && rect1.x2 > rect2.x1 && rect1.y1 < rect2.y2 && rect1.y2 > rect2.y1_x000D_
  };_x000D_
}_x000D_
$(window).on("load scroll resize", function() {_x000D_
  var viewportOffset = getViewportOffset($("#element"));_x000D_
  $("#log").text("left: " + viewportOffset.left + ", top: " + viewportOffset.top + ", insideViewport: " + viewportOffset.insideViewport);_x000D_
});

When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

In another way,

If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”

There won't be any "merge commit" in fast-forwarding merge.

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

You can't put variable definitions in header files, as these will then be a part of all source file you include the header into.

The #pragma once is just to protect against multiple inclusions in the same source file, not against multiple inclusions in multiple source files.

You could declare the variables as extern in the header file, and then define them in a single source file. Or you could declare the variables as const in the header file and then the compiler and linker will manage it.

There really isn't any easy way to insert multiple spaces inside (or in the middle) of a paragraph. Those suggesting you use CSS are missing the point. You may not always be trying to indent a paragraph from a side but, in fact, trying to put extra spaces in a particular spot of it.

In essence, in this case, the spaces become the content and not the style. I don't know why so many people don't see that. I guess the rigidity with which they try to enforce the separation of style and content rule (HTML was designed to do both from the beginning - there is nothing wrong with occasionally defining style of an unique element using appropriate tags without having to spend a lot more time on creating CSS style sheets and there is absolutely nothing unreadable about it when it's used in moderation. There is also something to be said for being able to do something quickly.) translates to how they can only consider whitespace characters as being used only for style and indentation.

And when there is no graceful way to insert spaces without having to rely on   and   tags, I would argue that the resulting code becomes far more unreadible than if there was an appropriately named tag that would have allowed you to quickly insert a large number of spaces (or if, you know, spaces weren't needlessly consumed in the first place).

As it is though, as was said above, your best bet would be to use   to insert   in the correct place.

TL;DR

If you can use iotop, do so. Else this might help.

Use top, then use these shortcuts:

d 1 = set refresh time from 3 to 1 second

1   = show stats for each cpu, not cumulated

This has to show values > 1.0 wa for at least one core - if there are no diskwaits, there is simply no IO load and no need to look further. Significant loads usually start > 15.0 wa.

x       = highlight current sort column 
< and > = change sort column
R       = reverse sort order

Chose 'S', the process status column. Reverse the sort order so the 'R' (running) processes are shown on top. If you can spot 'D' processes (waiting for disk), you have an indicator what your culprit might be.

The way that worked for me, was to use my external IP Address.

If you don't know what it is, just google What's My IP

Then use your IP address and set this in your domains for the captcha and it should start working ok.

You can do just about any format you want with --pretty=format:

git log -1 --pretty=format:%h 

Above comments are both solid responses, however note that they aren't thread safe. If you are writing to the console with multiple threads, changing colors will add a race condition that can create some strange looking output. It is simple to fix though:

public class ConsoleWriter
{
    private static object _MessageLock= new object();

    public void WriteMessage(string message)
    {
        lock (_MessageLock)
        {
            Console.BackgroundColor = ConsoleColor.Red;
            Console.WriteLine(message);
            Console.ResetColor();
        }
    }
}

@A-312's solution may cause memory problems as it may create a huge array if /xampp/htdocs/WORK contains a lot of files and folders.

If you have PHP 7 then you can use Generators and optimize PHP's memory like this:

function getDirContents($dir) {
    $files = scandir($dir);
    foreach($files as $key => $value){

        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            yield $path;

        } else if($value != "." && $value != "..") {
           yield from getDirContents($path);
           yield $path;
        }
    }
}

foreach(getDirContents('/xampp/htdocs/WORK') as $value) {
    echo $value."\n";
}

yield from

If you need extract the text without the brackets, you can use bash awk

echo " [hola mundo] " | awk -F'[][]' '{print $2}'

result:

hola mundo

EDIT: This answer might be outdated if you're using a recent version of jQueryUI.

For an anchor to trigger the dialog -

<a href="http://ibm.com" class="example">

Here's the script -

$('a.example').click(function(){   //bind handlers
   var url = $(this).attr('href');
   showDialog(url);

   return false;
});

$("#targetDiv").dialog({  //create dialog, but keep it closed
   autoOpen: false,
   height: 300,
   width: 350,
   modal: true
});

function showDialog(url){  //load content and open dialog
    $("#targetDiv").load(url);
    $("#targetDiv").dialog("open");         
}

JObject obj = JObject.Parse(json);
var attributes = obj["parent"]["child"]...["your desired element"].ToList<JToken>(); 

foreach (JToken attribute in attributes)
{   
    JProperty jProperty = attribute.ToObject<JProperty>();
    string propertyName = jProperty.Name;
}

Update 27 Feb 2015: My original answer keeps getting voted up, but now I normally use @bobince's approach instead.

.child { /* This is the item to center... */
  display: inline-block;
}
.parent { /* ...and this is its parent container. */
  text-align: center;
}

My original post for historical purposes:

You might want to try this approach.

<div class="product_container">
    <div class="outer-center">
        <div class="product inner-center">
        </div>
    </div>
    <div class="clear"/>
</div>

Here's the matching style:

.outer-center {
    float: right;
    right: 50%;
    position: relative;
}
.inner-center {
    float: right;
    right: -50%;
    position: relative;
}
.clear {
    clear: both;
}

JSFiddle

The idea here is that you contain the content you want to center in two divs, an outer one and an inner one. You float both divs so that their widths automatically shrink to fit your content. Next, you relatively position the outer div with it's right edge in the center of the container. Lastly, you relatively position the inner div the opposite direction by half of its own width (actually the outer div's width, but they are the same). Ultimately that centers the content in whatever container it's in.

You may need that empty div at the end if you depend on your "product" content to size the height for the "product_container".

The only thing that worked for me was a combination of the above:

First the li in the ul

<li><a onclick="LoadTab2_1()" href="JavaScript:void(0)">All Assigned</a></li>

Then in the LoadTab2_1 I manually switched the tab divs.

$("#tabs-2-1").hide();
    $("#tabs-2-2").show();

This is because the disconnection of the also disconnects the action in the tabs.

You also need to manually do the tab styling when the primary tab changes things.

$("#secTab1").addClass("ui-tabs-active").addClass("ui-state-active").addClass("ui-state-hover").addClass("ui-state-focus");
    $("#secTab1 a").css("color", "#ffffff");

By default, it begins by processing the first target that does not begin with a . aka the default goal; to do that, it may have to process other targets - specifically, ones the first target depends on.

The GNU Make Manual covers all this stuff, and is a surprisingly easy and informative read.

you can simply add id to the button, it is not in the document, but it works.

$().dialog(buttons:[{id:'your button id'....}]);

then in your function just use the

$('#your button id') 

to disable it.
