I'm turning my comment to an answer, so it can be accepted and this question no longer remains unanswered.

The most likely cause of this is a malformed response, which includes characters before the initial <?xml …>. So please have a look at the document as transferred over HTTP, and fix this on the server side.

Another solution would be to save all commit logs to a file

git log > branch.log

Now branch.log will have all commit ids since beginning.. scroll down and take the first commit (this will be difficult in terminal) using the first commit

git reset --soft

all commits will be squashed

Try:

Excel.Application oXL;
Excel._Workbook oWB;
Excel._Worksheet oSheet;
Excel.Range oRng;

oXL = new Excel.Application();
oXL.Visible = true;
oWB = (Excel._Workbook)(oXL.Workbooks.Add(Missing.Value));

oSheet = (Excel._Worksheet)oWB.Worksheets;
oSheet.Activate();

oSheet.Cells[3, 9] = "Some Text"

I slightly modified your stored procedure (to use SCOPE_IDENTITY) and it looks like this:

CREATE PROCEDURE usp_InsertContract
    @ContractNumber varchar(7),
    @NewId int OUTPUT
AS
BEGIN
    INSERT INTO [dbo].[Contracts] (ContractNumber)
    VALUES (@ContractNumber)

    SELECT @NewId = SCOPE_IDENTITY()
END

I tried this and it works just fine (with that modified stored procedure):

// define connection and command, in using blocks to ensure disposal
using(SqlConnection conn = new SqlConnection(pvConnectionString ))
using(SqlCommand cmd = new SqlCommand("dbo.usp_InsertContract", conn))
{
    cmd.CommandType = CommandType.StoredProcedure;

    // set up the parameters
    cmd.Parameters.Add("@ContractNumber", SqlDbType.VarChar, 7);
    cmd.Parameters.Add("@NewId", SqlDbType.Int).Direction = ParameterDirection.Output;

    // set parameter values
    cmd.Parameters["@ContractNumber"].Value = contractNumber;

    // open connection and execute stored procedure
    conn.Open();
    cmd.ExecuteNonQuery();

    // read output value from @NewId
    int contractID = Convert.ToInt32(cmd.Parameters["@NewId"].Value);
    conn.Close();
}

Does this work in your environment, too? I can't say why your original code won't work - but when I do this here, VS2010 and SQL Server 2008 R2, it just works flawlessly....

If you don't get back a value - then I suspect your table Contracts might not really have a column with the IDENTITY property on it.

This does it:

Do
   c = c + 1
Loop While Cells(c, "A").Value <> ""

'prints the last empty row
Debug.Print c

Please take note before down voting, this solution is for Gimp using a graphical interface, and not for ImageMagick using a command line, but it worked perfectly fine for me as an alternative, and that is why I found it needful to share here.

Follow these simple steps to extract images in any format from PDF documents

1. Download GIMP Image Manipulation Program
2. Open the Program after installation
3. Open the PDF document that you want to extract Images
4. Select only the pages of the PDF document that you would want to extract images from. N/B: If you need only the cover images, select only the first page.
5. Click open after selecting the pages that you want to extract images from
6. Click on File menu when GIMP when the pages open
7. Select Export as in the File menu
8. Select your preferred file type by extension (say png) below the dialog box that pops up.
9. Click on Export to export your image to your desired location.
10. You can then check your file explorer for the exported image.

That's all.

I hope this helps

ModelMapper is another library worth checking out. ModelMapper's design is different from other libraries in that it:

• Automatically maps object models by intelligently matching source and destination properties
• Provides a refactoring safe mapping API that uses actual code to map fields and methods rather than using strings
• Utilizes convention based configuration for simple handling of custom scenarios

Check out the ModelMapper site for more info:

I think that your reasoning is sound. But in practice I have found that it is far more common to omit the === comparison. I think that there are three reasons for that:

1. It does not usually add to the meaning of the expression - that's in cases where the value is known to be boolean anyway.
2. Because there is a great deal of type-uncertainty in JavaScript, forcing a type check tends to bite you when you get an unexpected undefined or null value. Often you just want your test to fail in such cases. (Though I try to balance this view with the "fail fast" motto).
3. JavaScript programmers like to play fast-and-loose with types - especially in boolean expressions - because we can.

Consider this example:

var someString = getInput();
var normalized = someString && trim(someString);  
// trim() removes leading and trailing whitespace

if (normalized) {
    submitInput(normalized);
}

I think that this kind of code is not uncommon. It handles cases where getInput() returns undefined, null, or an empty string. Due to the two boolean evaluations submitInput() is only called if the given input is a string that contains non-whitespace characters.

In JavaScript && returns its first argument if it is falsy or its second argument if the first argument is truthy; so normalized will be undefined if someString was undefined and so forth. That means that none of the inputs to the boolean expressions above are actually boolean values.

I know that a lot of programmers who are accustomed to strong type-checking cringe when seeing code like this. But note applying strong typing would likely require explicit checks for null or undefined values, which would clutter up the code. In JavaScript that is not needed.

If someone uses jquery, he can do it like this :

var click_count = 0;
$( "canvas" ).bind( "click", function( event ) {
    //do whatever you want
    click_count++;
    if ( click_count == 50 ) {
        //remove the event
        $( this ).unbind( event );
    }
});

Hope that it can help someone. Note that the answer given by @user113716 work nicely :)

Just encountered the same problem after IntelliJ update. My fix: right click on the project, then maven -> reimport.

Try running this as a TSQL Script

SELECT 1
RETURN
SELECT 2
SELECT 3

The return ends the execution.

RETURN (Transact-SQL)

Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements that follow RETURN are not executed.

From the friendly Wikipedia:

The stdlib.h and stddef.h header files define a datatype called size_t which is used to represent the size of an object. Library functions that take sizes expect them to be of type size_t, and the sizeof operator evaluates to size_t.

The actual type of size_t is platform-dependent; a common mistake is to assume size_t is the same as unsigned int, which can lead to programming errors, particularly as 64-bit architectures become more prevalent.

Also, check Why size_t matters

Perhaps you could try using the DateTime.FromOADate method to convert between Excel and .net.

I faced the same issue and spent almost 15-16 tiring hours to clean, rebuild, invalidate-cache, upgrade Idea from 16.3 to 17.2, all in vain. We have a Maven managed project and the build used to be successful but just couldn't navigate between declaration/implementations as Idea couldn't see the files.

After endlessly trying to fix this, it finally dawned to me that it's the IDEA settings causing all the headache. This is what I did (Windows system):

1. Exit IDE
2. Recursively delete all .iml files from project directory del /s /q "C:\Dev\trunk\*.iml"
3. Find and delete all .idea folders
4. Delete contents of the caches, index, and LocalHistory folders under <user_home>\.IntelliJIdea2017.2\system
5. Open Idea and import project ....

VOILAAAAAAAAAAAA...!! I hope this helps a poor soul in pain

For Logging your request and response you need an interceptor and also for setting the header you need an interceptor, Here's the solution for adding both the interceptor at once using retrofit 2.1

 public OkHttpClient getHeader(final String authorizationValue ) {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient okClient = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .addNetworkInterceptor(
                        new Interceptor() {
                            @Override
                            public Response intercept(Interceptor.Chain chain) throws IOException {
                                Request request = null;
                                if (authorizationValue != null) {
                                    Log.d("--Authorization-- ", authorizationValue);

                                    Request original = chain.request();
                                    // Request customization: add request headers
                                    Request.Builder requestBuilder = original.newBuilder()
                                            .addHeader("Authorization", authorizationValue);

                                    request = requestBuilder.build();
                                }
                                return chain.proceed(request);
                            }
                        })
                .build();
        return okClient;

    }

Now in your retrofit object add this header in the client

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(url)
                .client(getHeader(authorizationValue))
                .addConverterFactory(GsonConverterFactory.create())
                .build();

I modified the code as follow:

ViewModel

using System.Collections.Generic;
using ContosoUniversity.Models;

namespace ContosoUniversity.ViewModels
{
    public class InstructorIndexData
    {
     public PagedList.IPagedList<Instructor> Instructors { get; set; }
     public PagedList.IPagedList<Course> Courses { get; set; }
     public PagedList.IPagedList<Enrollment> Enrollments { get; set; }
    }
}

Controller

public ActionResult Index(int? id, int? courseID,int? InstructorPage,int? CoursePage,int? EnrollmentPage)
{
 int instructPageNumber = (InstructorPage?? 1);
 int CoursePageNumber = (CoursePage?? 1);
 int EnrollmentPageNumber = (EnrollmentPage?? 1);
 var viewModel = new InstructorIndexData();
 viewModel.Instructors = db.Instructors
    .Include(i => i.OfficeAssignment)
    .Include(i => i.Courses.Select(c => c.Department))
    .OrderBy(i => i.LastName).ToPagedList(instructPageNumber,5);

 if (id != null)
 {
    ViewBag.InstructorID = id.Value;
    viewModel.Courses = viewModel.Instructors.Where(
        i => i.ID == id.Value).Single().Courses.ToPagedList(CoursePageNumber,5);
 }

 if (courseID != null)
 {
    ViewBag.CourseID = courseID.Value;
    viewModel.Enrollments = viewModel.Courses.Where(
        x => x.CourseID == courseID).Single().Enrollments.ToPagedList(EnrollmentPageNumber,5);
 }

 return View(viewModel);
}

View

<div>
   Page @(Model.Instructors.PageCount < Model.Instructors.PageNumber ? 0 : Model.Instructors.PageNumber) of @Model.Instructors.PageCount

   @Html.PagedListPager(Model.Instructors, page => Url.Action("Index", new {InstructorPage=page}))

There seems no way to have google maps api key free without credit card. To test the functionality of google map you can use it while leaving the api key field "EMPTY". It will show a message saying "For Development Purpose Only". And that way you can test google map functionality without putting billing information for google map api key.

<script src="https://maps.googleapis.com/maps/api/js?key=&callback=initMap" async defer></script>

You can use something like componentDidUpdate

componentDidUpdate() {
  var elem = testNode //your ref to the element say testNode in your case; 
  elem.scrollTop = elem.scrollHeight;
};

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

change it to:

$(function () {

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

    });  
});

and it will work.

C version of @Nayfe code, generating SHA1 hash from file:

#include <stdio.h>
#include <openssl/sha.h>

static const int K_READ_BUF_SIZE = { 1024 * 16 };
unsigned char* calculateSHA1(char *filename)
{
    if (!filename) {
        return NULL;
    }

    FILE *fp = fopen(filename, "rb");
    if (fp == NULL) {
        return NULL;
    }

    unsigned char* sha1_digest = malloc(sizeof(char)*SHA_DIGEST_LENGTH);
    SHA_CTX context;

    if(!SHA1_Init(&context))
        return NULL;

    unsigned char buf[K_READ_BUF_SIZE];
    while (!feof(fp))
    {
        size_t total_read = fread(buf, 1, sizeof(buf), fp);
        if(!SHA1_Update(&context, buf, total_read))
        {
            return NULL;
        }
    }
    fclose(fp);

    if(!SHA1_Final(sha1_digest, &context))
        return NULL;

    return sha1_digest;
}

It can be used as follows:

unsigned char *sha1digest = calculateSHA1("/tmp/file1");

The res variable contains the sha1 hash.

You can print it on the screen using the following for-loop:

char *sha1hash = (char *)malloc(sizeof(char) * 41);
sha1hash[41] = '\0';
int i;
for (i = 0; i < SHA_DIGEST_LENGTH; i++)
{
    sprintf(&sha1hash[i*2], "%02x", sha1digest[i]);
}
printf("SHA1 HASH: %s\n", sha1hash);

Use pass for no-op:

if x == 0:
  pass
else:
  print "x not equal 0"

And here's another example:

def f():
  pass

Or:

class c:
  pass

First Check that is image exists? if yes then simply Call unlink(your file path) function to remove you file otherwise show message to the user.

              if (file_exists($filePath)) 
               {
                 unlink($filePath);
                  echo "File Successfully Delete."; 
              }
              else
              {
               echo "File does not exists"; 
              }

The report might want to access a DataSource or DataView where the AD user (or AD group) has insuficcient access rights.

Make sure you check out the following URLs:

Then choose Folder Settings

(or the appropriate individual DataSource or DataSet) and select Security. The user group needs to have the Browser permission.

I would use the shebang #!/usr/bin/python (first line of code) with the serial number of Python at the end ;)

Then run the Python file as a script, e.g., ./main.py from the command line, rather than python main.py.

It is the same when you want to run Python from a Linux command line.

Old question, but hopefully this'll help someone else.

In my case I was using a toolchain on Ubuntu 12.04 that was built on Ubuntu 10.04 (requires GCC 4.1 to build). As most of the libraries have moved to multiarch dirs, it couldn't find ld.so. So, make a symlink for it.

Check required path:

$ readelf -a arm-linux-gnueabi-gcc | grep interpreter:
      [Requesting program interpreter: /lib/ld-linux-x86-64.so.2]

Create symlink:

$ sudo ln -s /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /lib/ld-linux-x86-64.so.2

If you're on 32bit, it'll be i386-linux-gnu and not x86_64-linux-gnu.

Try the following:

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost.*$ [NC] 
RewriteRule \.(gif|jpg)$ - [F]

Returns 403, if you access images directly, but allows them to be displayed on site.

Note: It is possible that when you open some page with image and then copy that image's path into the address bar you can see that image, it is only because of the browser's cache, in fact that image has not been loaded from the server (from Davo, full comment below).

Just like any other text file, .js files have specific encodings they are saved in. This message means you are saving the .js file with a non-UTF8 encoding (probably ASCII), and so your non-ASCII characters never even make it to the disk.

That is, the problem is not at the level of HTML or <meta charset> or Content-Type headers, but instead a very basic issue of how your text file is saved to disk.

To fix this, you'll need to change the encoding that Dreamweaver saves files in. It looks like this page outlines how to do so; choose UTF8 without saving a Byte Order Mark (BOM). This Super User answer (to a somewhat-related question) even includes screenshots.

I had the same problem, so I wrote this. It works rather well. Looks great if you mix it with some CSS transitions.

function toggle_visibility(id) {
   var e = document.getElementById("mjwelcome");
   if(e.style.height == '')
      e.style.height = '0px';
   else
      e.style.height = '';
}

This is an old, answered, question, but @Alexandre asked "Why would anyone want to do this?", and I thought that I might provide an example usage that I am considering this afternoon.

Legacy code. Uses naked pointers Obj*obj with a delete obj at the end.

Unfortunately I need sometimes, not often, to keep the object alive longer.

I am considering making it a reference counted smart pointer. But there would be lots of code to change, if I was to use ref_cnt_ptr<Obj> everywhere. And if you mix naked Obj* and ref_cnt_ptr, you can get the object implicitly deleted when the last ref_cnt_ptr goes away, even though there are Obj* still alive.

So I am thinking about creating an explicit_delete_ref_cnt_ptr. I.e. a reference counted pointer where the delete is only done in an explicit delete routine. Using it in the one place where the existing code knows the lifetime of the object, as well as in my new code that keeps the object alive longer.

Incrementing and decrementing the reference count as explicit_delete_ref_cnt_ptr get manipulated.

But NOT freeing when the reference count is seen to be zero in the explicit_delete_ref_cnt_ptr destructor.

Only freeing when the reference count is seen to be zero in an explicit delete-like operation. E.g. in something like:

template<typename T> class explicit_delete_ref_cnt_ptr { 
 private: 
   T* ptr;
   int rc;
   ...
 public: 
   void delete_if_rc0() {
      if( this->ptr ) {
        this->rc--;
        if( this->rc == 0 ) {
           delete this->ptr;
        }
        this->ptr = 0;
      }
    }
 };

OK, something like that. It's a bit unusual to have a reference counted pointer type not automatically delete the object pointed to in the rc'ed ptr destructor. But it seems like this might make mixing naked pointers and rc'ed pointers a bit safer.

But so far no need for delete this.

But then it occurred to me: if the object pointed to, the pointee, knows that it is being reference counted, e.g. if the count is inside the object (or in some other table), then the routine delete_if_rc0 could be a method of the pointee object, not the (smart) pointer.

class Pointee { 
 private: 
   int rc;
   ...
 public: 
   void delete_if_rc0() {
        this->rc--;
        if( this->rc == 0 ) {
           delete this;
        }
      }
    }
 };

Actually, it doesn't need to be a member method at all, but could be a free function:

map<void*,int> keepalive_map;
template<typename T>
void delete_if_rc0(T*ptr) {
        void* tptr = (void*)ptr;
        if( keepalive_map[tptr] == 1 ) {
           delete ptr;
        }
};

(BTW, I know the code is not quite right - it becomes less readable if I add all the details, so I am leaving it like this.)

Use the stopPropagation method:

event.stopPropagation();

check Robocopy:

For a new path to be added to PATH environment variable in MacOS just create a new file under /etc/paths.d directory and add write path to be set in the file. Restart the terminal. You can check with echo $PATH at the prompt to confirm if the path was added to the environment variable.

For example: to add a new path /usr/local/sbin to the PATH variable:

cd /etc/paths.d
sudo vi newfile

Add the path to the newfile and save it.

Restart the terminal and type echo $PATH to confirm

plt.subplots() is a function that returns a tuple containing a figure and axes object(s). Thus when using fig, ax = plt.subplots() you unpack this tuple into the variables fig and ax. Having fig is useful if you want to change figure-level attributes or save the figure as an image file later (e.g. with fig.savefig('yourfilename.png')). You certainly don't have to use the returned figure object but many people do use it later so it's common to see. Also, all axes objects (the objects that have plotting methods), have a parent figure object anyway, thus:

fig, ax = plt.subplots()

is more concise than this:

fig = plt.figure()
ax = fig.add_subplot(111)

Thanks Oleg Vaskevich. Using a WeakReference of the FragmentActivity solved the problem. My code looks as follows now:

public class MyFragmentActivity extends FragmentActivity implements OnFriendAddedListener {

    private static WeakReference<MyFragmentActivity> wrActivity = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        wrActivity = new WeakReference<MyFragmentActivity>(this);
        ...

    private class onFriendAddedAsyncTask extends AsyncTask<String, Void, String> {

        @Override
        protected void onPreExecute() {
            FragmentManager fm = getSupportFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();
            DummyFragment dummyFragment = DummyFragment.newInstance();
            ft.add(R.id.dummy_fragment_layout, dummyFragment);
            ft.commit();
        }

        @Override
        protected void onPostExecute(String result) {
            final Activity activity = wrActivity.get();
            if (activity != null && !activity.isFinishing()) {
                FragmentManager fm = activity.getSupportFragmentManager();
                FragmentTransaction ft = fm.beginTransaction();
                DummyFragment dummyFragment = (DummyFragment) fm.findFragmentById(R.id.dummy_fragment_layout);
                ft.remove(dummyFragment);
                ft.commitAllowingStateLoss();
            }
        }

Just add the line below to the <TextInput>

These all look a bit more complicated than they need to be. My code is very simple and fast:

def fibonacci(x):

    List = []
    f = 1
    List.append(f)
    List.append(f) #because the fibonacci sequence has two 1's at first
    while f<=x:
        f = List[-1] + List[-2]   #says that f = the sum of the last two f's in the series
        List.append(f)
    else:
        List.remove(List[-1])  #because the code lists the fibonacci number one past x. Not necessary, but defines the code better
        for i in range(0, len(List)):
        print List[i]  #prints it in series form instead of list form. Also not necessary

Use !=. See comparison operators. For comparing object identities, you can use the keyword is and its negation is not.

e.g.

1 == 1 #  -> True
1 != 1 #  -> False
[] is [] #-> False (distinct objects)
a = b = []; a is b # -> True (same object)

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

this is what it worked for me:

select * from table
where column
BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
 AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

Please, note that I had to change STR_TO_DATE(column, '%d/%m/%Y') from previous solutions, as it was taking ages to load

Bit reversal in pseudo code

source -> byte to be reversed b00101100 destination -> reversed, also needs to be of unsigned type so sign bit is not propogated down

copy into temp so original is unaffected, also needs to be of unsigned type so that sign bit is not shifted in automaticaly

bytecopy = b0010110

LOOP8: //do this 8 times test if bytecopy is < 0 (negative)

    set bit8 (msb) of reversed = reversed | b10000000 

else do not set bit8

shift bytecopy left 1 place
bytecopy = bytecopy << 1 = b0101100 result

shift result right 1 place
reversed = reversed >> 1 = b00000000
8 times no then up^ LOOP8
8 times yes then done.

Write-Back is a more complex one and requires a complicated Cache Coherence Protocol(MOESI) but it is worth it as it makes the system fast and efficient.

The only benefit of Write-Through is that it makes the implementation extremely simple and no complicated cache coherency protocol is required.

I had a simmilar problem, but all the suggestions didn't help.

However, the problem was the *.png itself. It had no alpha channel. Somehow Xcode ignores all png files without alpha channel during the deploy process.

After searching constantly, this is the solution that worked for me which entails unsetting/removing the Upstream

git branch --unset-upstream

Perhaps appending DateTime.Now.Ticks instead, is a tiny bit faster since you won't be creating 3 strings and the ticks value will always be unique also.

Here's a solution using simpler functions and no hacks:

all.equal(a, as.integer(a))

What's more, you can test a whole vector at once, if you wish. Here's a function:

testInteger <- function(x){
  test <- all.equal(x, as.integer(x), check.attributes = FALSE)
  if(test == TRUE){ return(TRUE) }
  else { return(FALSE) }
}

You can change it to use *apply in the case of vectors, matrices, etc.

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

Do this instead:

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

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

docker rmi -f $(docker images -a|awk 'NR > 1 && $2 == "" {print $3}')

That's true, element in Set are not ordered, by definition of the Set Collection. So they can't be access by an index.

But why don't we have a get(object) method, not by providing the index as parameter, but an object that is equal to the one we are looking for? By this way, we can access the data of the element inside the Set, just by knowing its attributes used by the equal method.

What I have observed is: if you use openssl to generate certificates, it captures both the text part and the base64 certificate part in the crt file. The strict pem format says (wiki definition) that the file should start and end with BEGIN and END.

.pem – (Privacy Enhanced Mail) Base64 encoded DER certificate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"

So for some libraries (I encountered this in java) that expect strict pem format, the generated crt would fail the validation as an 'invalid pem format'.

Even if you copy or grep the lines with BEGIN/END CERTIFICATE, and paste it in a cert.pem file, it should work.

Here is what I do, not very clean, but works for me, basically it filters the text starting from BEGIN line:

grep -A 1000 BEGIN cert.crt > cert.pem

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

Overload less than operator, then sort. This is an example I found off the web...

public:
  int m_iData;
  string m_strSomeOtherData;
  bool operator<(const MyData &rhs) const { return m_iData < rhs.m_iData; }
};

one fast and simple way is to make the div as

Gulp doesn't offer any kind of util for that, but you can use one of the many command args parsers. I like yargs. Should be:

var argv = require('yargs').argv;

gulp.task('my-task', function() {
    return gulp.src(argv.a == 1 ? options.SCSS_SOURCE : options.OTHER_SOURCE)
        .pipe(sass({style:'nested'}))
        .pipe(autoprefixer('last 10 version'))
        .pipe(concat('style.css'))
        .pipe(gulp.dest(options.SCSS_DEST));
});

You can also combine it with gulp-if to conditionally pipe the stream, very useful for dev vs. prod building:

var argv = require('yargs').argv,
    gulpif = require('gulp-if'),
    rename = require('gulp-rename'),
    uglify = require('gulp-uglify');

gulp.task('my-js-task', function() {
  gulp.src('src/**/*.js')
    .pipe(concat('out.js'))
    .pipe(gulpif(argv.production, uglify()))
    .pipe(gulpif(argv.production, rename({suffix: '.min'})))
    .pipe(gulp.dest('dist/'));
});

And call with gulp my-js-task or gulp my-js-task --production.

Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.

I use this alert

<div class="alert alert-error hidden" id="successfulSave">
  <span>
    <p>Success! Result Saved.</p>
  </span>
</div>

repeatedly on a page each time a user updates a result successfully:

$('#successfulSave').removeClass('hidden');

to re-hide it, I call

$('#successfulSave').addClass('hidden');

Just to add to the solution presented, in my case I wanted to fetch multiple data from Firebase for a list of products. Here is how I did it:

useEffect(() => {
  const fn = p => firebase.firestore().doc(`products/${p.id}`).get();
  const actions = data.occasion.products.map(fn);
  const results = Promise.all(actions);
  results.then(data => {
    const newProducts = [];
    data.forEach(p => {
      newProducts.push({ id: p.id, ...p.data() });
    });
    setProducts(newProducts);
  });
}, [data]);

Here's a good reference on the different formatting you can use with regard to the date:

http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc38151.1510/html/iqrefbb/Convert.htm

instead of just table name, you can also write a query for getting only selected column data.

COPY (select id,name from tablename) TO 'filepath/aa.csv' DELIMITER ',' CSV HEADER;

with admin privilege

\COPY (select id,name from tablename) TO 'filepath/aa.csv' DELIMITER ',' CSV HEADER;

Console.Read() takes a character and returns the ascii value of that character.So if you want to take the symbol that was entered by the user instead of its ascii value (ex:if input is 5 then symbol = 5, ascii value is 53), you have to parse it using int.parse() but it raises a compilation error because the return value of Console.Read() is already int type. So you can get the work done by using Console.ReadLine() instead of Console.Read() as follows.

int userInput = int.parse(Console.ReadLine());

here, the output of the Console.ReadLine() would be a string containing a number such as "53".By passing it to the int.Parse() we can convert it to int type.

Did you check the Spring Boot reference docs?

By default Spring Boot will serve static content from a folder called /static (or /public or /resources or /META-INF/resources) in the classpath or from the root of the ServletContext.

You can also compare your project with the guide Serving Web Content with Spring MVC, or check out the source code of the spring-boot-sample-web-ui project.

The easiest solution is to override SaveChanges on your entities class. You can catch the DbEntityValidationException, unwrap the actual errors and create a new DbEntityValidationException with the improved message.

1. Create a partial class next to your SomethingSomething.Context.cs file.
2. Use the code at the bottom of this post.
3. That's it. Your implementation will automatically use the overriden SaveChanges without any refactor work.

Your exception message will now look like this:

System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The validation errors are: The field PhoneNumber must be a string or array type with a maximum length of '12'; The LastName field is required.

You can drop the overridden SaveChanges in any class that inherits from DbContext:

public partial class SomethingSomethingEntities
{
    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException ex)
        {
            // Retrieve the error messages as a list of strings.
            var errorMessages = ex.EntityValidationErrors
                    .SelectMany(x => x.ValidationErrors)
                    .Select(x => x.ErrorMessage);
    
            // Join the list to a single string.
            var fullErrorMessage = string.Join("; ", errorMessages);
    
            // Combine the original exception message with the new one.
            var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
    
            // Throw a new DbEntityValidationException with the improved exception message.
            throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
        }
    }
}

The DbEntityValidationException also contains the entities that caused the validation errors. So if you require even more information, you can change the above code to output information about these entities.

You can use dictionary.map like this:

let myKeys: [String] = myDictionary.map{String($0.key) }

The explanation: Map iterates through the myDictionary and accepts each key and value pair as $0. From here you can get $0.key or $0.value. Inside the trailing closure {}, you can transform each element and return that element. Since you want $0 and you want it as a string then you convert using String($0.key). You collect the transformed elements to an array of strings.

This is how you do it in your $(document).ready() function with FontAwesome Icons:

 $( ".owl-prev").html('<i class="fa fa-chevron-left"></i>');
 $( ".owl-next").html('<i class="fa fa-chevron-right"></i>');

Dictionary<int,string> comboSource = new Dictionary<int,string>();
comboSource.Add(1, "Sunday");
comboSource.Add(2, "Monday");

Aftr adding values to Dictionary, use this as combobox datasource:

comboBox1.DataSource = new BindingSource(comboSource, null);
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";

This works:

inputValue = Math.Round(inputValue, 2);

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

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

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

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

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

then this is what you want:

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

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

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

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

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

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

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

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

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

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

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

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

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

TL;DR

Error #1064 means that MySQL can't understand your command. To fix it:

• Read the error message. It tells you exactly where in your command MySQL got confused.

• Examine your command. If you use a programming language to create your command, use echo, console.log(), or its equivalent to show the entire command so you can see it.

• Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.

• Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).

1. Aaaagh!! What does #1064 mean?

   Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.

   As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.

   • What is this "syntax" of which you speak? Is it witchcraft?

     Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.

     For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):

     This sentence contains syntax error a.

   • What does that have to do with MySQL?

     Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.

     It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.

2. How do I fix it?

   Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…

   • Read the message!

     MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:

     UPDATE my_table WHERE id=101 SET name='foo'
     

     That command yields the following error message:

     ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1

     MySQL is telling us that everything seemed fine up to the word WHERE, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE at that point.

     Messages that say ...near '' at line... simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.

   • Examine the actual text of your command!

     Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:

     $result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
     

     If you write this this in two lines

     $query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
     $result = $mysqli->query($query);
     

     then you can add echo $query; or var_dump($query) to see that the query actually says

     UPDATE userSET name='foo' WHERE id=101
     

     Often you'll see your error immediately and be able to fix it.

   • Obey orders!

     MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.

     I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE command. The very first thing on the page is the command's grammar (this is true for every command):

     UPDATE [LOW_PRIORITY] [IGNORE] table_reference
         SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
         [WHERE where_condition]
         [ORDER BY ...]
         [LIMIT row_count]
     

     The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [ and ] are optional; vertical bars | indicate alternatives; and ellipses ... denote either an omission for brevity, or that the preceding clause may be repeated.

     We already know that the parser believed everything in our command was okay prior to the WHERE keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference must be followed by the SET keyword: whereas in our command it was actually followed by the WHERE keyword. This explains why the parser reports that a problem was encountered at that point.

   A note of reservation

   Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.

   I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:

   UPDATE my_table SET where='foo'
   

   Again, the parser does not expect to encounter WHERE at this point and so will raise a similar syntax error—but you hadn't intended for that where to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:

   If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.

   [ deletia ]

   The identifier quote character is the backtick (“`”):

   mysql> SELECT * FROM `select` WHERE `select`.id > 100;

   If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:

   mysql> CREATE TABLE "test" (col INT);
   ERROR 1064: You have an error in your SQL syntax...
   mysql> SET sql_mode='ANSI_QUOTES';
   mysql> CREATE TABLE "test" (col INT);
   Query OK, 0 rows affected (0.00 sec)

You can list the attributes of a object with dir() in the shell:

>>> dir(object())
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Of course, there is also the inspect module: http://docs.python.org/library/inspect.html#module-inspect

You can not put

$connection = sqlite_open("[path]/data/users.sqlite", 0666);

outside the class construction. You have to put that line inside a function or the constructor but you can not place it where you have now.

you can put your elements into an array and hash at the same time.

var value = [1,2,3];
ahash = {"one": value};
array.push(value);

array can be used to get values by their order and hash could be used to get values by their key. just be be carryfull when you remove and add elements.

Some solution is first to copy() the file (as mentioned above) and when the destination file exists - unlink() file from previous localization. Additionally you can validate the MD5 checksum before unlinking to be sure

l.insert(index, obj) doesn't actually return anything. It just updates the list.

As ATO said, you can do b = a[:index] + [obj] + a[index:]. However, another way is:

a = [1, 2, 4]
b = a[:]
b.insert(2, 3)

You need to give a function to be called after the time delay as the second argument to after:

after(delay_ms, callback=None, *args)

Registers an alarm callback that is called after a given time.

So what you really want to do is this:

tiles_letter = ['a', 'b', 'c', 'd', 'e']

def add_letter():
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles


root.after(0, add_letter)  # add_letter will run as soon as the mainloop starts.
root.mainloop()

You also need to schedule the function to be called again by repeating the call to after inside the callback function, since after only executes the given function once. This is also noted in the documentation:

The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself

Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter to make sure the list isn't empty, and just return if it is:

def add_letter():
    if not tiles_letter:
        return
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles

We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups.

$ rpm -qf /bin/kafka-consumer-groups
confluent-kafka-2.11-1.1.1-1.noarch

For example:

$ kafka-consumer-groups --describe --group logstash | grep -E "TOPIC|filebeat"
Note: This will not show information about old Zookeeper-based consumers.

Random Tip

NOTE: We use an alias that overloads kafka-consumer-groups like so in our /etc/profile.d/kafka.sh:

alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\"  kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"

I will answer this question in terms of AngularFire, Firebase's library for Angular.

1. Tl;dr: superpowers. :-)

2. AngularFire's three-way data binding. Angular binds the view and the $scope, i.e., what your users do in the view automagically updates in the local variables, and when your JavaScript updates a local variable the view automagically updates. With Firebase the cloud database also updates automagically. You don't need to write $http.get or $http.put requests, the data just updates.

3. Five-way data binding, and seven-way, nine-way, etc. I made a tic-tac-toe game using AngularFire. Two players can play together, with the two views updating the two $scopes and the cloud database. You could make a game with three or more players, all sharing one Firebase database.

4. AngularFire's OAuth2 library makes authorization easy with Facebook, GitHub, Google, Twitter, tokens, and passwords.

5. Double security. You can set up your Angular routes to require authorization, and set up rules in Firebase about who can read and write data.

6. There's no back end. You don't need to make a server with Node and Express. Running your own server can be a lot of work, require knowing about security, require that someone do something if the server goes down, etc.

7. Fast. If your server is in San Francisco and the client is in San Jose, fine. But for a client in Bangalore connecting to your server will be slower. Firebase is deployed around the world for fast connections everywhere.

You could do this

WITH V(A,B) AS (VALUES 
     (2555,111111259)    
    ,(2724,111111261)     
    ,(2021,111111263)    
    ,(2017,111111264)    

    )
SELECT COUNT(*) FROM NEW TABLE (
    UPDATE table
    SET id =     (SELECT B FROM V WHERE ID = A)
    WHERE EXISTS (SELECT B FROM V WHERE ID = A)
) 

Note, does not works on column organized tables. Use MERGE in that case

setInterval()

setInterval is a time interval based code execution method that has the native ability to repeatedly run specified script when the interval is reached. It should not be nested into its callback function by the script author to make it loop, since it loops by default. It will keep firing at the interval unless you call clearInterval().

if you want to loop code for animations or clocks Then use setInterval.

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setInterval(doStuff, 5000);

setTimeout()

setTimeout is a time based code execution method that will execute script only one time when the interval is reached, and not repeat again unless you gear it to loop the script by nesting the setTimeout object inside of the function it calls to run. If geared to loop, it will keep firing at the interval unless you call clearTimeout().

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setTimeout(doStuff, 5000);

if you want something to happen one time after some seconds Then use setTimeout... because it only executes one time when the interval is reached.

Values $_GET are always strings – that's what GET paramters come as. Therefore, is_int($_GET[...]) is always false.

You can test if a string consists only of digits(i.e. could be interpreted as a number) with is_numeric.

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

Use Random class from dart:math:

import 'dart:math';

main() {
  var rng = new Random();
  for (var i = 0; i < 10; i++) {
    print(rng.nextInt(100));
  }
}

This code was tested with the Dart VM and dart2js, as of the time of this writing.

The easiest way to import the exact numbers is to add a decimal after the numbers in your l1 and l2. Python interprets this decimal point as instructions from you to include the exact number. If you need to restrict it to some decimal place, you should be able to create a print command that limits the output, something simple like:

print variable_example[:13]

Would restrict it to the tenth decimal place, assuming your data has two integers left of the decimal.

Using

<a href="foo.html"><div class="xyz"></div></a>

works in browsers, even though it violates current HTML specifications. It is permitted according to HTML5 drafts.

When you say that it does not work, you should explain exactly what you did (including jsfiddle code is a good idea), what you expected, and how the behavior different from your expectations.

It is unclear what you mean by “all the content in that div is in the css”, but I suppose it means that the content is really empty in HTML markup and you have CSS like

.xyz:before { content: "Hello world"; }

The entire block is then clickable, with the content text looking like link text there. Isn’t this what you expected?

Edit your code in any linux environment then you won't face this problem. If edit in windows notepad any space take it as ^M.

With 'Enter' is better use ReadLine() or Read(2), because key 'Enter' generate 2 symbols. If user enter any text next Pause() also wil be skipped even with Read(2). So ReadLine() is better:

Sub Pause()
    WScript.Echo ("Press Enter to continue")
    z = WScript.StdIn.ReadLine()
End Sub

For those having the percentages in a pandas Series, here is my implemantation of the Largest remainder method (as in Varun Vohra's answer), where you can even select the decimals to which you want to round.

import numpy as np

def largestRemainderMethod(pd_series, decimals=1):

    floor_series = ((10**decimals * pd_series).astype(np.int)).apply(np.floor)
    diff = 100 * (10**decimals) - floor_series.sum().astype(np.int)
    series_decimals = pd_series - floor_series / (10**decimals)
    series_sorted_by_decimals = series_decimals.sort_values(ascending=False)

    for i in range(0, len(series_sorted_by_decimals)):
        if i < diff:
            series_sorted_by_decimals.iloc[[i]] = 1
        else:
            series_sorted_by_decimals.iloc[[i]] = 0

    out_series = ((floor_series + series_sorted_by_decimals) / (10**decimals)).sort_values(ascending=False)

    return out_series

I already have used Reportlab in one project.

For a (left outer) join of a table Bar with a table Foo on Foo.Foo_Id = Bar.Foo_Id in lambda notation:

var qry = Foo.GroupJoin(
          Bar, 
          foo => foo.Foo_Id,
          bar => bar.Foo_Id,
          (x,y) => new { Foo = x, Bars = y })
       .SelectMany(
           x => x.Bars.DefaultIfEmpty(),
           (x,y) => new { Foo=x.Foo, Bar=y});

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

With using pathlib module, indentation isn't needed.

import pathlib
pathlib.Path("output.txt").write_text("Purchase Amount: {}" .format(TotalAmount))

As of python 3.6, f-strings is available.

pathlib.Path("output.txt").write_text(f"Purchase Amount: {TotalAmount}")

If you should need to replace the handle with something else entirely, rather than just restyling it:

You can specify custom handle elements by creating and appending the elements and adding the ui-slider-handle class before initialization.

Working Example

$('.slider').append('<div class="my-handle ui-slider-handle"><svg height="18" width="14"><path d="M13,9 5,1 A 10,10 0, 0, 0, 5,17z"/></svg></div>');_x000D_
_x000D_
$('.slider').slider({_x000D_
  range: "min",_x000D_
  value: 10_x000D_
});

.slider .ui-state-default {_x000D_
  background: none;_x000D_
}_x000D_
.slider.ui-slider .ui-slider-handle {_x000D_
  width: 14px;_x000D_
  height: 18px;_x000D_
  margin-left: -5px;_x000D_
  top: -4px;_x000D_
  border: none;_x000D_
  background: none;_x000D_
}_x000D_

There are 3 kind of object files.

Relocatable object files

Contain machine code in a form that can be combined with other relocatable object files at link time, in order to form an executable object file.

If you have an a.c source file, to create its object file with GCC you should run: gcc a.c -c

The full process would be: preprocessor (cpp) would run over a.c. Its output (still source) will feed into the compiler (cc1). Its output (assembly) will feed into the assembler (as), which will produce the relocatable object file. That file contains object code and linking (and debugging if -g was used) metadata, and is not directly executable.

Shared object files

Special type of relocatable object file that can be loaded dynamically, either at load time, or at run time. Shared libraries are an example of these kinds of objects.

Executable object files

Contain machine code that can be directly loaded into memory (by the loader, e.g execve) and subsequently executed.

The result of running the linker over multiple relocatable object files is an executable object file. The linker merges all the input object files from the command line, from left-to-right, by merging all the same-type input sections (e.g. .data) to the same-type output section. It uses symbol resolution and relocation.

Bonus read:

When linking against a static library the functions that are referenced in the input objects are copied to the final executable. With dynamic libraries a symbol table is created instead that will enable a dynamic linking with the library's functions/globals. Thus, the result is a partially executable object file, as it depends on the library. If the library doesn't exist, the file can no longer execute).

The linking process can be done as follows: ld a.o -o myexecutable

The command: gcc a.c -o myexecutable will invoke all the commands mentioned at point 1 and at point 3 (cpp -> cc1 -> as -> ld¹)

1: actually is collect2, which is a wrapper over ld.

SQL Server has no setting to control query timeout in the connection string, and as far as I know this is the same for other major databases. But, this doesn't look like the problem you're seeing: I'd expect to see an exception raised

Error: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

if there genuinely was a timeout executing the query.

If this does turn out to be a problem, you can change the default timeout for a SQL Server database as a property of the database itself; use SQL Server Manager for this.

Be sure that the query is exactly the same from your Web application as the one you're running directly. Use a profiler to verify this.

Here is the simple version

 #one
 a = [[0]*10]*10

 #two
row, col = 10, 10
a = [[0]*row]*col

Close, you can use

$('#select_2 option:selected').html()

I wrote this to remove all objects apart from functions from the current environment (Programming language used is R with IDE R-Studio):

    remove_list=c()                             # create a vector

      for(i in 1:NROW(ls())){                   # repeat over all objects in environment
        if(class(get(ls()[i]))!="function"){    # if object is *not* a function
         remove_list=c(remove_list,ls()[i])     # ..add to vector remove_list
         }    
      }

    rm(list=remove_list)                        # remove all objects named in remove_list

Notes-

The argument "list" in rm(list=) must be a character vector.

The name of an object in position i of the current environment is returned from ls()[i] and the object itself from get(ls()[i]). Therefore the class of an object is returned from class(get(ls()[i]))

To use nodemon you must install it globally.

For Windows

npm i -g nodemon

For Mac

sudo npm i -g nodemon

If you don't want to install it globally you can install it locally in your project folder by running command npm i nodemon . It will give error something like this if run locally:

nodemon : The term 'nodemon' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling
of the name, or if a path was included, verify that the path is
correct and try again.

To remove this error open package.json file and add

"scripts": {
     "server": "nodemon server.js"
 },

and after that just run command

npm run server

and your nodemon will start working properly.

Here's how i am calling my modal

<a data-toggle="modal" data-id="190" data-target="#modal-popup">Open</a>

Here's how i am obtaining value in the modal

$('#modal-popup').on('show.bs.modal', function(e) {
    console.log($(e.relatedTarget).data('id')); // 190 will be printed
});

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "scr", "javascript:test();", true);

This for all needs of date-time converting

 <?php
 $newDate = new DateTime('2019-03-27 03:41:41');
 echo $newDate->format('M d, Y, h:i:s a');
 ?>

Run a single test called MyTest:

./gradlew app:testDebug --tests=com.example.MyTest

<meta name="format-detection" content="telephone=no">. This metatag works in the default Safari browser on iOS devices and will only work for telephone numbers that are not wrapped in a telephone link so

1-800-123-4567
<a href="tel:18001234567">1-800-123-4567</a>

the first line will not be formatted as a link if you specify the metatag but the second line will because it's wrapped in a telephone anchor.

You can forego the metatag all-together and use a mixin such as

a[href^=tel]{
    color:inherit;
    text-decoration:inherit;
    font-size:inherit;
    font-style:inherit;
    font-weight:inherit;
}

to maintain intended styling of your telephone numbers, but you must make sure you wrap them in a telephone anchor.

If you want to be extra cautious and protect against the event of a telephone number which is not properly formatted with a wrapping anchor tag you can drill through the DOM and adjust with this script. Adjust the replacement pattern as desired.

$('body').html($('body').html().replace(/^\D?(\d{3})\D?\D?(\d{3})\D?(\d{4})/g, '<a href="tel:+1$1$2$3">($1) $2-$3</a>'));

or even better without jQuery

document.body.innerHTML = document.body.innerHTML.replace(/^\D?(\d{3})\D?\D?(\d{3})\D?(\d{4})/g,'<a href="tel:+1$1$2$3">($1) $2-$3</a>');

Because you have a very simple CORS policy (Allow all requests from XXX domain), you don't need to make it so complicated. Try doing the following first (A very basic implementation of CORS).

If you haven't already, install the CORS nuget package.

Install-Package Microsoft.AspNetCore.Cors

In the ConfigureServices method of your startup.cs, add the CORS services.

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(); // Make sure you call this previous to AddMvc
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}

Then in your Configure method of your startup.cs, add the following :

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    // Make sure you call this before calling app.UseMvc()
    app.UseCors(
        options => options.WithOrigins("http://example.com").AllowAnyMethod()
    );

    app.UseMvc();
}

Now give it a go. Policies are for when you want different policies for different actions (e.g. different hosts or different headers). For your simple example you really don't need it. Start with this simple example and tweak as you need to from there.

You can also do that from inteface builder like this.

I think it's helpful.

Here's my solution:

toolbar.navigationIcon?.mutate()?.let {
  it.setTint(theColor)
  toolbar.navigationIcon = it
}

Or, if you want to use a nice function for it:

fun Toolbar.setNavigationIconColor(@ColorInt color: Int) = navigationIcon?.mutate()?.let {
    it.setTint(color)
    this.navigationIcon = it
}

Usage:

toolbar.setNavitationIconColor(someColor)

Using the canonical function to get the powerset from the the itertools recipe page:

from itertools import chain, combinations

def powerset(iterable):
    """
    powerset([1,2,3]) --> () (1,) (2,) (3,) (1,2) (1,3) (2,3) (1,2,3)
    """
    xs = list(iterable)
    # note we return an iterator rather than a list
    return chain.from_iterable(combinations(xs,n) for n in range(len(xs)+1))

Used like:

>>> list(powerset("abc"))
[(), ('a',), ('b',), ('c',), ('a', 'b'), ('a', 'c'), ('b', 'c'), ('a', 'b', 'c')]

>>> list(powerset(set([1,2,3])))
[(), (1,), (2,), (3,), (1, 2), (1, 3), (2, 3), (1, 2, 3)]

map to sets if you want so you can use union, intersection, etc...:

>>> map(set, powerset(set([1,2,3])))
[set([]), set([1]), set([2]), set([3]), set([1, 2]), set([1, 3]), set([2, 3]), set([1, 2, 3])]

>>> reduce(lambda x,y: x.union(y), map(set, powerset(set([1,2,3]))))
set([1, 2, 3])

I would recommend reading in the line into a string, then splitting it based on the spaces. For this, you can use the getline(...) function. The trick is having a dynamic sized data structure to hold the strings once it's split. Probably the easiest to use would be a vector.

#include <string>
#include <vector>
...
  string rawInput;
  vector<String> numbers;
  while( getline( cin, rawInput, ' ' ) )
  {
    numbers.push_back(rawInput);
  }

So say the input looks like this:

Enter a number, or numbers separated by a space, between 1 and 1000.
10 5 20 1 200 7

You will now have a vector, numbers, that contains the elements: {"10","5","20","1","200","7"}.

Note that these are still strings, so not useful in arithmetic. To convert them to integers, we use a combination of the STL function, atoi(...), and because atoi requires a c-string instead of a c++ style string, we use the string class' c_str() member function.

while(!numbers.empty())
{
  string temp = numbers.pop_back();//removes the last element from the string
  num = atoi( temp.c_str() ); //re-used your 'num' variable from your code

  ...//do stuff
}

Now there's some problems with this code. Yes, it runs, but it is kind of clunky, and it puts the numbers out in reverse order. Lets re-write it so that it is a little more compact:

#include <string>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  num = atoi( rawInput.c_str() );
  ...//do your stuff
}

There's still lots of room for improvement with error handling (right now if you enter a non-number the program will crash), and there's infinitely more ways to actually handle the input to get it in a usable number form (the joys of programming!), but that should give you a comprehensive start. :)

Note: I had the reference pages as links, but I cannot post more than two since I have less than 15 posts :/

Edit: I was a little bit wrong about the atoi behavior; I confused it with Java's string->Integer conversions which throw a Not-A-Number exception when given a string that isn't a number, and then crashes the program if the exception isn't handled. atoi(), on the other hand, returns 0, which is not as helpful because what if 0 is the number they entered? Let's make use of the isdigit(...) function. An important thing to note here is that c++ style strings can be accessed like an array, meaning rawInput[0] is the first character in the string all the way up to rawInput[length - 1].

#include <string>
#include <ctype.h>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  bool isNum = true;
  for(int i = 0; i < rawInput.length() && isNum; ++i)
  {
    isNum = isdigit( rawInput[i]);
  }

  if(isNum)
  {
    num = atoi( rawInput.c_str() );
    ...//do your stuff
  }
  else
    cout << rawInput << " is not a number!" << endl;
}

The boolean (true/false or 1/0 respectively) is used as a flag for the for-loop, which steps through each character in the string and checks to see if it is a 0-9 digit. If any character in the string is not a digit, the loop will break during it's next execution when it gets to the condition "&& isNum" (assuming you've covered loops already). Then after the loop, isNum is used to determine whether to do your stuff, or to print the error message.

Use Regex as below.

if (txtNumeric.Text.Length < 0 || !System.Text.RegularExpressions.Regex.IsMatch(txtNumeric.Text, "^[0-9]*$")) {
 MessageBox.show("add content");
} else {
 MessageBox.show("add content");
}

I had a simular need. Here is what I did:

  <script type="text/javascript" language="javascript">
    function convertEnterToTab() {
      if(event.keyCode==13) {
        event.keyCode = 9;
      }
    }
    document.onkeydown = convertEnterToTab;    
  </script>  

You could still use framework 4.0 but you have to include getawaiter for the classes:

MethodName(parameters).ConfigureAwait(false).GetAwaiter().GetResult();

Created a bat file with the below contents, it accepts the input for port number

@ECHO ON
set /p portid=Enter the Port to be killed: 
echo %portid%                                                                              
FOR /F "tokens=5" %%T IN ('netstat -a -n -o ^| findstr %portid% ') DO (
SET /A ProcessId=%%T) &GOTO SkipLine                                                   
:SkipLine                                                                              
echo ProcessId to kill = %ProcessId%
taskkill /f /pid %ProcessId%
PAUSE

Finally click "Enter" to exit.

This code makes a window with the conditions that the user cannot change the dimensions of the Tk() window, and also disables the maximise button.

import tkinter as tk

root = tk.Tk()
root.resizable(width=False, height=False)
root.mainloop()

Within the program you can change the window dimensions with @Carpetsmoker's answer, or by doing this:

root.geometry('{}x{}'.format(<widthpixels>, <heightpixels>))

It should be fairly easy for you to implement that into your code. :)

I hope I'm understanding the problem correctly, but it looks like you don't have a reference back to your DrawFrame object from DrawCircle.

Try this:

Change your constructor signature for DrawCircle to take in a DrawFrame object. Within the constructor, set the class variable "d" to the DrawFrame object you just took in. Now add the getWidth/getHeight methods to DrawFrame as mentioned in previous answers. See if that allows you to get what you're looking for.

Your DrawCircle constructor should be changed to something like:

public DrawCircle(DrawFrame frame)
{
    d = frame;
    w = 400;
    h = 400;
    diBig = 300;
    diSmall = 10;
    maxRad = (diBig/2) - diSmall;
    xSq = 50;
    ySq = 50;
    xPoint = 200;
    yPoint = 200;
}

The last line of code in DrawFrame should look something like:

contentPane.add(new DrawCircle(this));

Then, try using d.getheight(), d.getWidth() and so on within DrawCircle. This assumes you still have those methods available on DrawFrame to access them, of course.

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

Use above code in onResume() to open soft Keyboard

in my case this error resolved by adding permission level to root folder .

i previously only granted permission in 2 place. one in site setting and one in a new folder that has custom permission .

but the user permission to browse the root folder was also required. Note The "Folder setting" in root folder

another time i had similar problem and adding users in the following windows group SQLServerReportServerUser$servername$MSRS10_50.MSSQLSERVER and running IE as Administrator or turning off UAC resolved my problem .

You can also define a class for the bullets you want to show, so in the CSS:

ul {list-style:none; list-style-type:none; list-style-image:none;}

And in the HTML you just define which lists to show:

<ul style="list-style:disc;">

Or you alternatively define a CSS class:

.show-list {list-style:disc;}

Then apply it to the list you want to show:

<ul class="show-list">

All other lists won't show the bullets...

go to control panel -> manage your credentials and delete github credentials if any.

What you do is called a projection. That's when you return only a scalar value that belongs to one entity. You can do this with JPA. See scalar value.

I think in this case, omitting the entity type altogether is possible:

   Query query = em.createNativeQuery(  "select id from users where username = ?");  
   query.setParameter(1, "lt");  
   BigDecimal val = (BigDecimal) query.getSingleResult(); 

Example taken from here.

Try new way to set background transparent

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

In my case I wanted to use a Swift protocol in an Objective-C header file that comes from the same target and for this I needed to use a forward declaration of the Swift protocol to reference it in the Objective-C interface. The same should be valid for using a Swift class in an Objective-C header file. To use forward declaration see the following example from the docs at Include Swift Classes in Objective-C Headers Using Forward Declarations:

// MyObjcClass.h
@class MySwiftClass; // class forward declaration
@protocol MySwiftProtocol; // protocol forward declaration

@interface MyObjcClass : NSObject
- (MySwiftClass *)returnSwiftClassInstance;
- (id <MySwiftProtocol>)returnInstanceAdoptingSwiftProtocol;
// ...
@end

I really recommend you use jquery for the javascript calls and some implementation of JSR311 like jersey for the service layer, which would delegate to your controllers.

This will help you with all the underlying logic of handling the HTTP calls and your data serialization, which is a big help.

//if you want change
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings[key].Value = value;

//if you want add
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings.Add("key", value);

Here's an example of applying dropshadow to some svg using the 'filter' property. If you want to control the opacity of the dropshadow have a look at this example. The slope attribute controls how much opacity to give to the dropshadow.

Relevant bits from the example:

<filter id="dropshadow" height="130%">
  <feGaussianBlur in="SourceAlpha" stdDeviation="3"/> <!-- stdDeviation is how much to blur -->
  <feOffset dx="2" dy="2" result="offsetblur"/> <!-- how much to offset -->
  <feComponentTransfer>
    <feFuncA type="linear" slope="0.5"/> <!-- slope is the opacity of the shadow -->
  </feComponentTransfer>
  <feMerge> 
    <feMergeNode/> <!-- this contains the offset blurred image -->
    <feMergeNode in="SourceGraphic"/> <!-- this contains the element that the filter is applied to -->
  </feMerge>
</filter>
<circle r="10" style="filter:url(#dropshadow)"/>

Box-shadow is defined to work on CSS boxes (read: rectangles), while svg is a bit more expressive than just rectangles. Read the SVG Primer to learn a bit more about what you can do with SVG filters.

Updated answer that covers most cases

curl -H "Access-Control-Request-Method: GET" -H "Origin: http://localhost" --head http://www.example.com/

1. Replace http://www.example.com/ with URL you want to test.
2. If response includes Access-Control-Allow-* then your resource supports CORS.

Rationale for alternative answer

I google this question every now and then and the accepted answer is never what I need. First it prints response body which is a lot of text. Adding --head outputs only headers. Second when testing S3 URLs we need to provide additional header -H "Access-Control-Request-Method: GET".

Hope this will save time.

I think you're running into problems because RedHat uses RPM for managing packages. Debian based systems use DEBs, which are managed with tools like apt.

I faced the same issue with an ASP.NET MVC site when I tried to use LINQ to SQL. I fixed the problem by:

Even simpler one that I just wrote:

    public static string Indent = "    ";

    public static string PrettyPrint(string input)
    {
        var output = new StringBuilder(input.Length * 2);

        }

        return output.ToString();

}

Necessary extensions:

    public static string Repeat(this string str, int count)
    {
        return new StringBuilder().Insert(0, str, count).ToString();
    }

    public static bool IsEscaped(this string str, int index)
    {
        bool escaped = false;
        while (index > 0 && str[--index] == '\\') escaped = !escaped;
        return escaped;
    }

    public static bool IsEscaped(this StringBuilder str, int index)
    {
        return str.ToString().IsEscaped(index);

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;

That's it...

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}

Generally git pull is enough, but I'm not sure what layout you have chosen (or has github chosen for you).

        // Example: Adding a converter to a column (C#)
        Style styleReading = new Style(typeof(TextBlock));
        Setter s = new Setter();
        s.Property = TextBlock.ForegroundProperty;
        Binding b = new Binding();
        b.RelativeSource = RelativeSource.Self;
        b.Path = new PropertyPath(TextBlock.TextProperty);
        b.Converter = new ReadingForegroundSetter();
        s.Value = b;
        styleReading.Setters.Add(s);
        col.ElementStyle = styleReading;

For repeating an action in the future, there is the built in setInterval function that you can use instead of setTimeout.
It has a similar signature, so the transition from one to another is simple:

setInterval(function() {
    // do stuff
}, duration);

The fastest solution if you are not embedding js into your template is:

Put <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script> before your reference to script.js file in your template, then add csrfmiddlewaretoken into your data dictionary:

$.ajax({
            type: 'POST',
            url: somepathname + "do_it/",
            data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
            success: function() {
                console.log("Success!");
            }
        })

If you do embed your js into the template, it's as simple as: data: {csrfmiddlewaretoken: '{{ csrf_token }}'}

Here is another solution to this problem, with a focus on keeping the syntax as close to a standard foreach as possible.

This sort of construct is useful if you are wanting to make your views look nice and clean in MVC. For example instead of writing this the usual way (which is hard to format nicely):

 <%int i=0;
 foreach (var review in Model.ReviewsList) { %>
    <div id="review_<%=i%>">
        <h3><%:review.Title%></h3>                      
    </div>
    <%i++;
 } %>

You could instead write this:

 <%foreach (var review in Model.ReviewsList.WithIndex()) { %>
    <div id="review_<%=LoopHelper.Index()%>">
        <h3><%:review.Title%></h3>                      
    </div>
 <%} %>

I've written some helper methods to enable this:

public static class LoopHelper {
    public static int Index() {
        return (int)HttpContext.Current.Items["LoopHelper_Index"];
    }       
}

public static class LoopHelperExtensions {
    public static IEnumerable<T> WithIndex<T>(this IEnumerable<T> that) {
        return new EnumerableWithIndex<T>(that);
    }

    public class EnumerableWithIndex<T> : IEnumerable<T> {
        public IEnumerable<T> Enumerable;

        public EnumerableWithIndex(IEnumerable<T> enumerable) {
            Enumerable = enumerable;
        }

        public IEnumerator<T> GetEnumerator() {
            for (int i = 0; i < Enumerable.Count(); i++) {
                HttpContext.Current.Items["LoopHelper_Index"] = i;
                yield return Enumerable.ElementAt(i);
            }
        }

        IEnumerator IEnumerable.GetEnumerator() {
            return GetEnumerator();
        }
    }

In a non-web environment you could use a static instead of HttpContext.Current.Items.

This is essentially a global variable, and so you cannot have more than one WithIndex loop nested, but that is not a major problem in this use case.

You can create a symlink in /usr/local/bin/

sudo ln -s $HOME/.composer/vendor/bin/homestead /usr/local/bin/homestead

there is an important difference between delete and splice:

ORIGINAL ARRAY:

[<1 empty item>, 'one',<3 empty items>, 'five', <3 empty items>,'nine']

AFTER SPLICE (array.splice(1,1)):

[ <4 empty items>, 'five', <3 empty items>, 'nine' ]

AFTER DELETE (delete array[1]):

[ <5 empty items>, 'five', <3 empty items>, 'nine' ]

Hope this helps

This is caused by MySQL having a strict mode set which won’t allow INSERT or UPDATE commands with empty fields where the schema doesn’t have a default value set.

There are a couple of fixes for this.

First ‘fix’ is to assign a default value to your schema. This can be done with a simple ALTER command:

ALTER TABLE `details` CHANGE COLUMN `delivery_address_id` `delivery_address_id` INT(11) NOT NULL DEFAULT 0 ;

However, this may need doing for many tables in your database schema which will become tedious very quickly. The second fix is to remove sql_mode STRICT_TRANS_TABLES on the mysql server.

If you are using a brew installed MySQL you should edit the my.cnf file in the MySQL directory. Change the sql_mode at the bottom:

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
sql_mode=NO_ENGINE_SUBSTITUTION

Save the file and restart Mysql.

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

create an empty modal box on the current page and below is the ajax call you can see how to fetch the content in result from another html page.

 $.ajax({url: "registration.html", success: function(result){
            //alert("success"+result);
              $("#contentBody").html(result);
            $("#myModal").modal('show'); 

        }});

once the call is done you will get the content of the page by the result to then you can insert the code in you modal's content id using.

You can call controller and get the page content and you can show that in your modal.

below is the example of Bootstrap 3 modal in that we are loading content from registration.html page...

You have a lot of pointless jQuery in there, but the $compile service is actually super simple in this case:

.directive( 'test', function ( $compile ) {
  return {
    restrict: 'E',
    scope: { text: '@' },
    template: '<p ng-click="add()">{{text}}</p>',
    controller: function ( $scope, $element ) {
      $scope.add = function () {
        var el = $compile( "<test text='n'></test>" )( $scope );
        $element.parent().append( el );
      };
    }
  };
});

You'll notice I refactored your directive too in order to follow some best practices. Let me know if you have questions about any of those.

The best answer, IMO, is the function provided here:

http://www.jb.man.ac.uk/~slowe/cpp/itoa.html

It mimics the non-ANSI function provided by many libs.

char* itoa(int value, char* result, int base);

It's also lightning fast and optimizes well under -O3, and the reason you're not using c++ string_format() ... or sprintf is that they are too slow, right?

Slightly different problem for me from the answers given above. For me, the HTML markup was fine, but one of my columns in the javascript was missing and didn't match the html.

i.e.

<table id="companies-index-table" class="table table-responsive-sm table-striped">

                            <thead>
                            <tr>
                                <th>Id</th>
                                <th>Name</th>
                                <th>Created at</th>
                                <th>Updated at</th>
                                <th>Count</th>
                            </tr>
                            </thead>
                            <tbody>
                            @foreach($companies as $company)
                                <tr>
                                    <td>{{ $company->id }}</td>
                                    <td>{{ $company->name }}</td>
                                    <td>{{ $company->created_at }}</td>
                                    <td>{{ $company->updated_at }}</td>
                                    <td>{{ $company->count }}</td>
                                </tr>
                            @endforeach
                            </tbody>
                        </table>

My Script:-

<script>
        $(document).ready(function() {
            $('#companies-index-table').DataTable({
                serverSide: true,
                processing: true,
                responsive: true,
                    ajax: "{{ route('admincompanies.datatables') }}",
                columns: [
                    { name: 'id' },
                    { name: 'name' },
                    { name: 'created_at' },
                    { name: 'updated_at' },     <-- I was missing this line so my columns didn't match the thead section.
                    { name: 'count', orderable: false },
                ],
            });
        });
    </script>

How about this? I frequently use the CSS Flexible Box Layout to center something.

<div style="display: flex; justify-content: center;">_x000D_
  <img src="http://icons.iconarchive.com/icons/rokey/popo-emotions/128/big-smile-icon.png" style="width: 40px; height: 40px;" />_x000D_
</div>

Setting the warning level to 2 suppresses this messages. Don't know if it's the best solution as it also suppresses useful warnings.

Use the size() function.

>> size(A,2)

Ans =

   3

The second argument specifies the dimension of which number of elements are required which will be '2' if you want the number of columns.

In a talk about core containers internals in Python at PyCon 2012, Raymond Hettinger is suggesting to use [None] * n to pre-allocate the length you want.

The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.

On Ubuntu 14.04 I installed it from apt-get and it worked fine:

sudo apt-get install python-beautifulsoup

Then just do:

from BeautifulSoup import BeautifulSoup

Had the same problem in Xcode 10.1 and was able to resolve it. In path Project Target > Build Setting > No Common Blocks, I changed it to No.

• If solution contains more than one project, try building them one at a time.
• Try restart Visual Studio.
• Try restart Computer.
• Try "Rebuild all"
• Try "Clean Solution" then remove your "vspscc" files and "vssscc" files and then restart Visual Studio and then "Rebuild All".

Basically your query returns more than one result set. In API Docs uniqueResult() method says that Convenience method to return a single instance that matches the query, or null if the query returns no results

uniqueResult() method yield only single resultset

Never ever mix more languages.

<script type="text/javascript">
    var data = @Json.Encode(Model); // !!!! export data !!!!

    for(var prop in data){
      console.log( prop + " "+ data[prop]);
    }

In case of problem you can also try

@Html.Raw(Json.Encode(Model));

If you want to install a npm module globally, make sure to use the new -g flag, for example:

npm install forever -g

The general recommendations concerning npm module installation since 1.0rc (taken from blog.nodejs.org):

• If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project.
• If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable.

I just recently used this recommendations and it went down pretty smoothly. I installed forever globally (since it is a command line tool) and all my application modules locally.

However, if you want to use some modules globally (i.e. express or mongodb), take this advice (also taken from blog.nodejs.org):

Of course, there are some cases where you want to do both. Coffee-script and Express both are good examples of apps that have a command line interface, as well as a library. In those cases, you can do one of the following:

• Install it in both places. Seriously, are you that short on disk space? It’s fine, really. They’re tiny JavaScript programs.
• Install it globally, and then npm link coffee-script or npm link express (if you’re on a platform that supports symbolic links.) Then you only need to update the global copy to update all the symlinks as well.

The first option is the best in my opinion. Simple, clear, explicit. The second is really handy if you are going to re-use the same library in a bunch of different projects. (More on npm link in a future installment.)

I did not test one of those variations, but they seem to be pretty straightforward.

As shown in How does "not something we can merge" arise?, this error can arise from a typo in the branch name because you are trying to pull a branch that doesn't exist.

If that is not the problem (as in my case), it is likely that you don't have a local copy of the branch that you want to merge. Git requires local knowledge of both branches in order to merge those branches. You can resolve this by checking out the branch to merge and then going back to the branch you want to merge into.

git checkout branch-name
git checkout master
git merge branch-name

This should work, but if you receive an error saying

error: pathspec 'remote-name/branch-name' did not match any file(s) known to git.

you need to fetch the remote (probably, but not necessarily, "origin") before checking out the branch:

git fetch remote-name

A global function that can be reused:

function getCheckedGroupBoxes(groupName) {

    var checkedAry= [];
    $.each($("input[name='" + groupName + "']:checked"), function () {
        checkedAry.push($(this).attr("id"));
    });

     return checkedAry;

}

where the groupName is the name of the group of the checkboxes, in you example :'options[]'

Simply place normal button indide Ajax.BeginForm and on click find parent form and normal submit. Ajax form in Razor:

@using (Ajax.BeginForm("AjaxPost", "Home", ajaxOptions))
    {        
        <div class="form-group">
            <div class="col-md-12">

                <button class="btn btn-primary" role="button" type="button" onclick="submitParentForm($(this))">Submit parent from Jquery</button>
            </div>
        </div>
    }

and Javascript:

function submitParentForm(sender) {
    var $formToSubmit = $(sender).closest('form');

    $formToSubmit.submit();

This link explains where you're going wrong:

[35.12] Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file?

Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.

This offers another solution:

How can I avoid linker errors with my template functions?

However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.

Anomies answer is good, but I felt insecure about this so I decided to add a couple of screenshots.

Step 0: git log

See where you are with git log. Most important, find the commit hash of the first commit you don't want to squash. So only the :

Step 1: git rebase

Execute git rebase -i [your hash], in my case:

$ git rebase -i 2d23ea524936e612fae1ac63c95b705db44d937d

Step 2: pick / squash what you want

In my case, I want to squash everything on the commit that was first in time. The ordering is from first to last, so exactly the other way as in git log. In my case, I want:

Step 3: Adjust message(s)

If you have picked only one commit and squashed the rest, you can adjust one commit message:

That's it. Once you save this (:wq), you're done. Have a look at it with git log.

If you want to ensure that your cleanup process finishes I would add on to Matt J's answer by using a SIG_IGN so that further SIGINT are ignored which will prevent your cleanup from being interrupted.

import signal
import sys

def signal_handler(signum, frame):
    signal.signal(signum, signal.SIG_IGN) # ignore additional signals
    cleanup() # give your process a chance to clean up
    sys.exit(0)

signal.signal(signal.SIGINT, signal_handler) # register the signal with the signal handler first
do_stuff()

Getting one month ago is easy with a single MySQL function:

SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH);

or

SELECT NOW() - INTERVAL 1 MONTH;

Off the top of my head, I can't think of an elegant way to get the first day of last month in MySQL, but this will certainly work:

SELECT CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01');

Put them together and you get a query that solves your problem:

SELECT *
FROM your_table
WHERE t >= CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01')
AND t <= NOW() - INTERVAL 1 MONTH

There is also a way to do this without loops using the DataTable.Compute Method. The following example comes from that page. You can see that the code used is pretty simple.:

private void ComputeBySalesSalesID(DataSet dataSet)
{
    // Presumes a DataTable named "Orders" that has a column named "Total."
    DataTable table;
    table = dataSet.Tables["Orders"];

    // Declare an object variable. 
    object sumObject;
    sumObject = table.Compute("Sum(Total)", "EmpID = 5");
}

I must add that if you do not need to filter the results, you can always pass an empty string:

sumObject = table.Compute("Sum(Total)", "")

Right click the database itself, Tasks -> Generate Scripts...

Then follow the wizard.

For SSMS2008+, if you want to also export the data, on the "Set Scripting Options" step, select the "Advanced" button and change "Types of data to script" from "Schema Only" to "Data Only" or "Schema and Data".

So, it turns out that X11 wasn't actually installed on the centOS. There didn't seem to be any indication anywhere of it not being installed. I did the following command and now firefox opens:

yum groupinstall 'X Window System' 

Hope this answer will help others that are confused :)

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

I hope this helps someone here: I encountered an issue where I needed to use JavaScript to manipulate some dynamically generated elements. After including the code to my external .js file which I had referenced to between the <script> </script> tags at the head section and it was working perfectly, nothing worked again from the script.Tried using developer tool on FF and it returned null value for the variable holding the new element. I decided to move my script tag to the bottom of the html file just before the </body> tag and bingo every part of the script started to respond fine again.

I have faced similar issue when importing on mac.i have python 3.7.3 installed Following steps helped me resolve it:

1. pip3 uninstall dnspython
2. sudo -H pip3 install dnspython

Import dns

Import dns.resolver

I had the same problem. This issue worked for me. In storyboard select your table view and change it from static cells into dynamic cells.

All of these are kinds of indices.

primary: must be unique, is an index, is (likely) the physical index, can be only one per table.

unique: as it says. You can't have more than one row with a tuple of this value. Note that since a unique key can be over more than one column, this doesn't necessarily mean that each individual column in the index is unique, but that each combination of values across these columns is unique.

index: if it's not primary or unique, it doesn't constrain values inserted into the table, but it does allow them to be looked up more efficiently.

fulltext: a more specialized form of indexing that allows full text search. Think of it as (essentially) creating an "index" for each "word" in the specified column.

A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.

A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.

A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :

A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.

An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.

If you're using Visual Studio Code, replace

app.run(debug=True)

with

app.run()

It appears when turning on the internal debugger disables the VS Code debugger.

NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.

For example, you could read your cube directly from a file into an array:

x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))

Sum along the second dimension:

s = x.sum(axis=1)

Find which cells are above a threshold:

(x > 0.5).nonzero()

Remove every even-indexed slice along the third dimension:

x[:, :, ::2]

Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.

Even if you don't have performance problems, learning NumPy is worth the effort.

$badData = 'a:2:{i:0;s:16:"as:45:"d";
Is \n";i:1;s:19:"as:45:"d";
Is \r\n";}';

You can not fix a broken serialize string using the proposed regexes:

$data = preg_replace('!s:(\d+):"(.*?)";!e', "'s:'.strlen('$2').':\"$2\";'", $badData);
var_dump(@unserialize($data)); // Output: bool(false)

// or

$data = preg_replace_callback(
    '/s:(\d+):"(.*?)";/',
    function($m){
        return 's:' . strlen($m[2]) . ':"' . $m[2] . '";';
    },
    $badData
);
var_dump(@unserialize($data)); // Output: bool(false)

You can fix broken serialize string using following regex:

$data = preg_replace_callback(
    '/(?<=^|\{|;)s:(\d+):\"(.*?)\";(?=[asbdiO]\:\d|N;|\}|$)/s',
    function($m){
        return 's:' . strlen($m[2]) . ':"' . $m[2] . '";';
    },
    $badData
);

var_dump(@unserialize($data));

Output

array(2) {
  [0] =>
  string(17) "as:45:"d";
Is \n"
  [1] =>
  string(19) "as:45:"d";
Is \r\n"
}

or

array(2) {
  [0] =>
  string(16) "as:45:"d";
Is \n"
  [1] =>
  string(18) "as:45:"d";
Is \r\n"
}

Using std::copy but without extra trailing separator

An alternative/modified approach using std::copy (as originally used in @JoshuaKravtiz answer) but without including an additional trailing separator after the last element:

#include <algorithm>
#include <iostream>
#include <iterator>
#include <vector>

template <typename T>
void print_contents(const std::vector<T>& v, const char * const separator = " ")
{
    if(!v.empty())
    {
        std::copy(v.begin(),
                  --v.end(),
                  std::ostream_iterator<T>(std::cout, separator));
        std::cout << v.back() << "\n";
    }
}

// example usage
int main() {
    std::vector<int> v{1, 2, 3, 4};
    print_contents(v);      // '1 2 3 4'
    print_contents(v, ":"); // '1:2:3:4'
    v = {};
    print_contents(v);      // ... no std::cout
    v = {1};
    print_contents(v);      // '1'
    return 0;
}

Example usage applied to container of a custom POD type:

// includes and 'print_contents(...)' as above ...

class Foo
{
    int i;
    friend std::ostream& operator<<(std::ostream& out, const Foo& obj);
public:
    Foo(const int i) : i(i) {}
};

std::ostream& operator<<(std::ostream& out, const Foo& obj)
{
    return out << "foo_" << obj.i; 
}

int main() {
    std::vector<Foo> v{1, 2, 3, 4};
    print_contents(v);      // 'foo_1 foo_2 foo_3 foo_4'
    print_contents(v, ":"); // 'foo_1:foo_2:foo_3:foo_4'
    v = {};
    print_contents(v);      // ... no std::cout
    v = {1};
    print_contents(v);      // 'foo_1'
    return 0;
}

Not tested, but something like this:

var now = new Date();
var str = now.getUTCFullYear().toString() + "/" +
          (now.getUTCMonth() + 1).toString() +
          "/" + now.getUTCDate() + " " + now.getUTCHours() +
          ":" + now.getUTCMinutes() + ":" + now.getUTCSeconds();

Of course, you'll need to pad the hours, minutes, and seconds to two digits or you'll sometimes get weird looking times like "2011/12/2 19:2:8."

The following statement appends the value to the element with the id of response

$('#response').append(total);

This makes it look like you are concatenating the strings, but you aren't, you're actually appending them to the element

change that to

$('#response').text(total);

You need to change the drop event so that it replaces the value of the element with the total, you also need to keep track of what the total is, I suggest something like the following

$(function() {
    var data = [];
    var total = 0;

    $( "#draggable1" ).draggable();
    $( "#draggable2" ).draggable();
    $( "#draggable3" ).draggable();

    $("#droppable_box").droppable({
        drop: function(event, ui) {
        var currentId = $(ui.draggable).attr('id');
        data.push($(ui.draggable).attr('id'));

        if(currentId == "draggable1"){
            var myInt1 = parseFloat($('#MealplanCalsPerServing1').val());
        }
        if(currentId == "draggable2"){
            var myInt2 = parseFloat($('#MealplanCalsPerServing2').val());
        }
        if(currentId == "draggable3"){
            var myInt3 = parseFloat($('#MealplanCalsPerServing3').val());
        }
        if ( typeof myInt1 === 'undefined' || !myInt1 ) {
            myInt1 = parseInt(0);
        }
        if ( typeof myInt2 === 'undefined' || !myInt2){
            myInt2 = parseInt(0);
        }
        if ( typeof myInt3 === 'undefined' || !myInt3){
        myInt3 = parseInt(0);
        }
        total += parseFloat(myInt1 + myInt2 + myInt3);
        $('#response').text(total);
        }
    });

    $('#myId').click(function(event) {
        $.post("process.php", ({ id: data }), function(return_data, status) {
            alert(data);
            //alert(total);
        });
    });
});

I moved the var total = 0; statement out of the drop event and changed the assignment statment from this

total = parseFloat(myInt1 + myInt2 + myInt3);

to this

total += parseFloat(myInt1 + myInt2 + myInt3);
