NetBeans has a built-in profiler.

in my case this worked perfectly

<img  style="border-radius: 50%;height: 50px;width: 80px;"  src="<?php echo asset("storage/TeacherImages/{$studydata->teacher->profilePic}")?>">

this code is used to display image from folder

Use ==:

pip install django_modeltranslation==0.4.0-beta2

Here is a plotrix solution:

set.seed(0815)
x <- 1:10
F <- runif(10,1,2) 
L <- runif(10,0,1)
U <- runif(10,2,3)

require(plotrix)
plotCI(x, F, ui=U, li=L)

And here is a ggplot solution:

set.seed(0815)
df <- data.frame(x =1:10,
                 F =runif(10,1,2),
                 L =runif(10,0,1),
                 U =runif(10,2,3))

require(ggplot2)
ggplot(df, aes(x = x, y = F)) +
  geom_point(size = 4) +
  geom_errorbar(aes(ymax = U, ymin = L))

UPDATE: Here is a base solution to your edits:

set.seed(1234)
x <- rnorm(20)
df <- data.frame(x = x,
                 y = x + rnorm(20))

plot(y ~ x, data = df)

# model
mod <- lm(y ~ x, data = df)

# predicts + interval
newx <- seq(min(df$x), max(df$x), length.out=100)
preds <- predict(mod, newdata = data.frame(x=newx), 
                 interval = 'confidence')

# plot
plot(y ~ x, data = df, type = 'n')
# add fill
polygon(c(rev(newx), newx), c(rev(preds[ ,3]), preds[ ,2]), col = 'grey80', border = NA)
# model
abline(mod)
# intervals
lines(newx, preds[ ,3], lty = 'dashed', col = 'red')
lines(newx, preds[ ,2], lty = 'dashed', col = 'red')

Find the folder containing the shared library libopencv_core.so.2.4 using the following command line.

sudo find / -name "libopencv_core.so.2.4*"

Then I got the result:

 /usr/local/lib/libopencv_core.so.2.4.

Create a file called /etc/ld.so.conf.d/opencv.conf and write to it the path to the folder where the binary is stored.For example, I wrote /usr/local/lib/ to my opencv.conf file. Run the command line as follows.

sudo ldconfig -v

Try to run the command again.

There are two ways to go about this. You can either use the IDE to generate a WSDL, or you can do it via the command line.

1. To create it via the IDE:

In the solution explorer pane, right click on the project that you would like to add the Service to:

Then, you can enter the path to your service WSDL and hit go:

2. To create it via the command line:

Open a VS 2010 Command Prompt (Programs -> Visual Studio 2010 -> Visual Studio Tools)
Then execute:

WSDL /verbose C:\path\to\wsdl

WSDL.exe will then output a .cs file for your consumption.

If you have other dependencies that you received with the file, such as xsd's, add those to the argument list:

WSDL /verbose C:\path\to\wsdl C:\path\to\some\xsd C:\path\to\some\xsd

If you need VB output, use /language:VB in addition to the /verbose.

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

myHash.each{|item|..} is returning you array object for item iterative variable like the following :--

[:company_name, "MyCompany"]
[:street, "Mainstreet"]
[:postcode, "1234"]
[:city, "MyCity"]
[:free_seats, "3"]

You should do this:--

def format
  output = Hash.new
  myHash.each do |k, v|
    output[k] = cleanup(v)
  end
  output
end

New version - psql 12 - will support --csv.

psql - devel

--csv

Switches to CSV (Comma-Separated Values) output mode. This is equivalent to \pset format csv.

---

csv_fieldsep

Specifies the field separator to be used in CSV output format. If the separator character appears in a field's value, that field is output within double quotes, following standard CSV rules. The default is a comma.

Usage:

psql -c "SELECT * FROM pg_catalog.pg_tables" --csv  postgres

psql -c "SELECT * FROM pg_catalog.pg_tables" --csv -P csv_fieldsep='^'  postgres

psql -c "SELECT * FROM pg_catalog.pg_tables" --csv  postgres > output.csv

Use max width and max height. It will keep the aspect ratio

#container img 
{
 max-width: 250px;
 max-height: 250px;
}

1 open /etc/sudoers

type sudo vi /etc/sudoers. This will open your file in edit mode.

2 Add/Modify linux user

Look for the entry for Linux user. Modify as below if found or add a new line.

<USERNAME> ALL=(ALL) NOPASSWD: ALL

3 Save and Exit from edit mode

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

Are these servers virtualized? On another post I've read about a SQL server running sometimes very slowly because of lack of sufficient memory. This in turn was caused by a so-called memory balloon that the virtualizer used to limit the amount of memory used by that virtual server. It was hard to find because the pressure on physical memory had nothing to do with the SQL server itself.

Another common cause for a temporary performance degradation might be a virus scanner. When a new virus definition is installed, all other processes will suffer and run very slow. Check out any other automatic update process, this might also take a lot of resources quite unexpectedly. Good luck with it!

if you want pressed image button then image should be change from normal to pressed

But I best way will be to customize the RadioButton and use them in a group. I have see an example of that. Sorry I did not remember that link.

but if you want to avoid that. You need to add this to your selector.xml

Once Done. Just got to your code and add this

public void onClick ( View v ) {
    myImageButton.setSelected ( true ) ;
 }

You will see the result. But you have to mange the states which button was recently press. So that you can set

  myOLDImageButton.setSelected ( false ) ;

I suggest you to put all button reference in a array.

Today, there is a ::marker option. so,

li::marker {
  content: "\2605";
}

merge into x as target using y as Source on target.ID = Source.ID
when not matched by target then insert
when matched then update
when not matched by source and target.ID is not null then
update whatevercolumn = 'isdeleted' ;

you'd use any of these:

JSTL c:forEach varStatus properties

Property Getter Description

• current getCurrent() The item (from the collection) for the current round of iteration.

• index getIndex() The zero-based index for the current round of iteration.

• count getCount() The one-based count for the current round of iteration

• first isFirst() Flag indicating whether the current round is the first pass through the iteration

• last isLast() Flag indicating whether the current round is the last pass through the iteration

• begin getBegin() The value of the begin attribute

• end getEnd() The value of the end attribute

• step getStep() The value of the step attribute

You have to define a path in the "Project compiler output" field in

File > Project Structure... > Project > Project compiler output

This path will be used to store all project compilation results.

Better solution is to introduce another interface for async operations. New interface must inherit from original interface.

Example:

interface IIO
{
    void DoOperation();
}

interface IIOAsync : IIO
{
    Task DoOperationAsync();
}


class ClsAsync : IIOAsync
{
    public void DoOperation()
    {
        DoOperationAsync().GetAwaiter().GetResult();
    }

    public async Task DoOperationAsync()
    {
        //just an async code demo
        await Task.Delay(1000);
    }
}


class Program
{
    static void Main(string[] args)
    {
        IIOAsync asAsync = new ClsAsync();
        IIO asSync = asAsync;

        Console.WriteLine(DateTime.Now.Second);

        asAsync.DoOperation();
        Console.WriteLine("After call to sync func using Async iface: {0}", 
            DateTime.Now.Second);

        asAsync.DoOperationAsync().GetAwaiter().GetResult();
        Console.WriteLine("After call to async func using Async iface: {0}", 
            DateTime.Now.Second);

        asSync.DoOperation();
        Console.WriteLine("After call to sync func using Sync iface: {0}", 
            DateTime.Now.Second);

        Console.ReadKey(true);
    }
}

P.S. Redesign your async operations so they return Task instead of void, unless you really must return void.

Once you have the source trees, e.g.

diff -ENwbur repos1/ repos2/ 

Even better

diff -ENwbur repos1/ repos2/  | kompare -o -

and have a crack at it in a good gui tool :)

• -Ewb ignore the bulk of whitespace changes
• -N detect new files
• -u unified
• -r recurse

Explanation from the Preshing on Programming blog:

It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:

 with open('output.txt', 'w') as f:
     f.write('Hi there!')

The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.

var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));

var d = new Date(res);
var month = d.getMonth() + 1;
var day = d.getDate();

var output = d.getFullYear() + '/' +
    (month < 10 ? '0' : '') + month + '/' +
    (day < 10 ? '0' : '') + day;

$('#txtEndDate').val(output);

Unless you write your own Homescreen launcher or use an existing one from Goolge Play, there's "no way" to resize icons.

Well, "no way" does not mean its impossible:

• As said, you can write your own launcher as discussed in Stackoverflow.
• You can resize elements on the home screen, but these elements are AppWidgets. Since API level 14 they can be resized and user can - in limits - change the size. But that are Widgets not Shortcuts for launching icons.

I think I have an Idea on how to deal with this. Updating is the same as deleting and replacing at the exact position. So I first remove the item from that position using the code below:

public void removeItem(int position){
    mData.remove(position);
    notifyItemRemoved(position);
    notifyItemRangeChanged(position, mData.size());
}

and then I would add the item at that particular position as shown below:

public void addItem(int position, Landscape landscape){
    mData.add(position, landscape);
    notifyItemInserted(position);
    notifyItemRangeChanged(position, mData.size());
}

I'm trying to implement this now. I would give you a feedback when I'm through!

Sliding the space bar only works if you gave more then one input language selected.

In that case the space bar will also indicate the selected language and show arrows to indicate Sliding will change selection.

This is easy fast and changes the dictionary at the same time.

First response seems the mist accurate.

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1

Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.

DataGridView1.Columns[0].Width=100;// The id column 
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining 
//space

The issue may happen while fetching dependencies from a remote repository. In my case, the repository did not need any authentication and it has been resolved by removing the servers section in the settings.xml file:

<servers>
    <server>
      <id>SomeRepo</id>
      <username>SomeUN</username>
      <password>SomePW</password>
    </server>
</servers>

ps: I guess your target is mvn clean install instead of maven install clean

I got a solution in python, I modified the webdriver class bassed on PersistenBrowser class that I found.

https://github.com/axelPalmerin/personal/commit/fabddb38a39f378aa113b0cb8d33391d5f91dca5

replace the webdriver module /usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py

Ej. to use:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

runDriver = sys.argv[1]
sessionId = sys.argv[2]

def setBrowser():
    if eval(runDriver):
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                     desired_capabilities=DesiredCapabilities.CHROME,
                     )
    else:
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                             desired_capabilities=DesiredCapabilities.CHROME,
                             session_id=sessionId)

    url = webdriver.command_executor._url
    session_id = webdriver.session_id
    print url
    print session_id
    return webdriver

As well as a conditional comment could also use CSS Browser Selector http://rafael.adm.br/css_browser_selector/ as this will allow you to target specific browsers. You can then set your CSS as

.ie .actual-form table {
    width: 100%
    }

This will also allow you to target specific browsers within your main stylesheet without the need for conditional comments.

I'd say like letiagoalves said, but you might have more than one checkbox question in your form, so I'd recommend to do like this:

  var limit = 3;
    $('input.single-checkbox').on('change', function(evt) {
        if($('input.single-checkbox').siblings('input.single-checkbox:checked').length > limit) {
            this.checked = false;
        }
    });

Probably a silly suggestion compared to others:

if(!preg_match("/^[a-zA-Z0-9]$/",$string)){
    $sortedString=preg_replace("/^[a-zA-Z0-9]+$/","",$string);
}

Starting from Python 3.1, you can use importlib :

import importlib  
foobar = importlib.import_module("foo-bar")

( https://docs.python.org/3/library/importlib.html )

I have solved this problem by adding a UIControl to the navigationBar on the left side .

UIControl *leftBarItemControl = [[UIControl alloc] initWithFrame:CGRectMake(0, 0, 90, 44)];
[leftBarItemControl addTarget:self action:@selector(onLeftItemClick:) forControlEvents:UIControlEventTouchUpInside];
self.leftItemControl = leftBarItemControl;
[self.navigationController.navigationBar addSubview:leftBarItemControl];
[self.navigationController.navigationBar bringSubviewToFront:leftBarItemControl];

And you need to remember to remove it when view will disappear:

- (void) viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    if (self.leftItemControl) {
        [self.leftItemControl removeFromSuperview];
    }    
}

That's all!

Had the issue too. (I'm running ubuntu 18.04)

What I did:

dpkg -l | grep -i nvidia

Then sudo apt-get remove --purge nvidia-381 (and every duplicate version, in my case I had 381, 384 and 387)

Then sudo ubuntu-drivers devices to list what's available

And I choose sudo apt install nvidia-driver-430

After that, nvidia-smi gave the correct output (no need to reboot). But I suppose you can reboot when in doubt.

I also followed this installation to reinstall cuda+cudnn.

Two ways I know of:

export class SomeComponent implements OnInit
{
    public localVar:any;

    ngOnInit(){
        this.http.get(Path).map(res => res.json()).subscribe(res => this.localVar = res);
    }
}

This will assign your result into local variable once information is returned just like in a promise. Then you just do {{ localVar }}

Another Way is to get a observable as a localVariable.

export class SomeComponent
{
    public localVar:any;

    constructor()
    {
        this.localVar = this.http.get(path).map(res => res.json());
    }
}

This way you're exposing a observable at which point you can do in your html is to use AsyncPipe {{ localVar | async }}

Please try it out and let me know if it works. Also, since angular 2 is pretty new, feel free to comment if something is wrong.

Hope it helps

hi the fastest (but not prettiest way) i found is

while (cleantext.indexOf("  ") != -1)
  cleantext = StringUtils.replace(cleantext, "  ", " ");

this is running pretty fast on android in opposite to an regex

The solution that work for is were add the next dependency to my pom.xml file.

An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...).

A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.

Some reasons you might want to use a setup.exe:

• Windows Installer only allows one MSI to be installing at a time. This means that it is difficult to have an MSI install other MSIs (e.g. dependencies like the .NET framework or C++ runtime). Since a setup.exe is not an MSI, it can be used to install several MSIs in sequence.
• You might want more precise control over how the installation is managed. An MSI has very specific rules about how it manages the installations, including installing, upgrading, and uninstalling. A setup.exe gives complete control over the software configuration process. This should only be done if you really need the extra control since it is a lot of work, and it can be tricky to get it right.

Should you instead be setting the identity insert to on within the stored procedure? It looks like you're setting it to on only when changing the stored procedure, not when actually calling it. Try:

ALTER procedure [dbo].[spInsertDeletedIntoTBLContent]
@ContentID int, 

SET IDENTITY_INSERT tbl_content ON

...insert command...

SET IDENTITY_INSERT tbl_content OFF
GO

Adding more info to the accepted answer, you can refer to my blog to see a running version of the code, using AWS Signature version 4.

Will summarize here:

As soon as the user selects a file to be uploaded, do the followings: 1. Make a call to the web server to initiate a service to generate required params

2. In this service, make a call to AWS IAM service to get temporary cred

3. Once you have the cred, create a bucket policy (base 64 encoded string). Then sign the bucket policy with the temporary secret access key to generate final signature

4. send the necessary parameters back to the UI

5. Once this is received, create a html form object, set the required params and POST it.

If you want to move down at the end of the page (so you don't need to scroll down to bottom) , you can use:

$('body').animate({ scrollTop: $(document).height() });

Just add -d32 to VM arguments in the "Edit launch configuration properties".

I just downloaded Git 2.7.0 and added an alias to the .bashrc for editing files with VS Code:

alias code='/c/Program\ Files\ \(x86\)/Microsoft\ VS\ Code/bin/code.cmd'

Should also work with other Editors...

Try this in your .htaccess:

.htaccess

ErrorDocument 404 http://example.com/404/
ErrorDocument 500 http://example.com/500/
# or map them to one error document:
# ErrorDocument 404 /pages/errors/error_redirect.php
# ErrorDocument 500 /pages/errors/error_redirect.php

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} ^/404/$
RewriteRule ^(.*)$ /pages/errors/404.php [L]

RewriteCond %{REQUEST_URI} ^/500/$
RewriteRule ^(.*)$ /pages/errors/500.php [L]

# or map them to one error document:
#RewriteCond %{REQUEST_URI} ^/404/$ [OR]
#RewriteCond %{REQUEST_URI} ^/500/$
#RewriteRule ^(.*)$ /pages/errors/error_redirect.php [L]

The ErrorDocument redirects all 404s to a specific URL, all 500s to another url (replace with your domain).

The Rewrite rules map that URL to your actual 404.php script. The RewriteCond regular expressions can be made more generic if you want, but I think you have to explicitly define all ErrorDocument codes you want to override.

Local Redirect:

Change .htaccess ErrorDocument to a file that exists (must exist, or you'll get an error):

ErrorDocument 404 /pages/errors/404_redirect.php

404_redirect.php

<?php
   header('Location: /404/');
   exit;
?>

Redirect based on error number

Looks like you'll need to specify an ErrorDocument line in .htaccess for every error you want to redirect (see: Apache ErrorDocument and Apache Custom Error). The .htaccess example above has multiple examples in it. You can use the following as the generic redirect script to replace 404_redirect.php above.

error_redirect.php

<?php
   $error_url = $_SERVER["REDIRECT_STATUS"] . '/';
   $error_path = $error_url . '.php';

   if ( ! file_exists($error_path)) {
      // this is the default error if a specific error page is not found
      $error_url = '404/';
   }

   header('Location: ' . $error_url);
   exit;
?>

I believe it means 'anything but a whitespace character'.

Just add layout_weight="1" to in your linearLayout which having Buttons.

Edit :- let me make it simple

follow something like below, tags name may not be correct, it is just an Idea

<LL>// Top Parrent LinearLayout
   <LL1 height="fill_parent" weight="1" "other tags as requirement"> <TV /><Butons /></LL1> // this layout will fill your screen.
   <LL2 height="wrap_content" weight="1"  orientation="Horizontal" "other tags as requirement"> <BT1 /><BT2/ ></LL2> // this layout gonna take lower part of button height of your screen

<LL/> TOP PARENT CLOSED

In Java, you really want to use Integer.toString to convert an integer to its corresponding String value. If you are dealing with just the digits 0-9, then you could use something like this:

private static final char[] DIGITS =
    {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

private static char getDigit(int digitValue) {
   assertInRange(digitValue, 0, 9);
   return DIGITS[digitValue];
}

Or, equivalently:

private static int ASCII_ZERO = 0x30;

private static char getDigit(int digitValue) {
  assertInRange(digitValue, 0, 9);
  return ((char) (digitValue + ASCII_ZERO));
}

1. Select the block of code that you want indented.

2. Right-click (or, on Mac, Ctrl-click).

3. Structure → Re-indent

Have you tried the exec command within the Runtime class?

Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug")

Runtime - Java Documentation

for Atom Users, Packages ->whitspace -> remove trailing whitespaces this worked for me

for multiple scripts, use this

var loadScript = function(src) {
  var tag = document.createElement('script');
  tag.async = false;
  tag.src = src;
  document.getElementsByTagName('body').appendChild(tag);
}
loadScript('//cdnjs.com/some/library.js')
loadScript('//cdnjs.com/some/other/library.js')

The good solution for this error please run this command

composer install --ignore-platform-reqs

This is an old thread, but I have just encountered this situation and discovered a neat way around it. I was trying to run a setup.exe, but the focus was returning to the next line of the script without waiting for the setup.exe to finish. I tried the above solutions with no luck.

In the end, piping the command through more did the trick.

setup.exe {arguments} | more

users=("kamal" "jamal" "rahim" "karim" "sadia")
index=()
t=-1

for i in ${users[@]}; do
  t=$(( t + 1 ))
  if [ $t -eq 0 ]; then
    for j in ${!users[@]}; do
      index[$j]=$j
    done
  fi
  echo "${index[$t]} is $i"
done

Intent intent=new Intent(String) is defined for parameter task, whereas you are passing parameter componentname into this, use instead:

Intent i = new Intent(Settings.this, com.scytec.datamobile.vd.gui.android.AppPreferenceActivity.class);
                    startActivity(i);

In this statement replace ActivityName by Name of Class of Activity, this code resides in.

In my case is a cookie-related issue, I had many cookies with value extremely big, and that was causing the problem.

You can replicate this issue here on stackoverflow.com, just open the console and type this:

[ ...Array(5) ].forEach((i, idx) => {
    document.cookie = `stackoverflow_cookie${idx}=${'a'.repeat(4000)}`;
});

What is that?

I am creating 5 cookies with a string of length or value of 4000 bytes; then reload the page and you will see the same issue.

I tried it on google.com and you'll get the error but they automatically clear the cookies for you, which is a nice fallback to start fresh.

Add keyword static to class declaration:

// this is a non-generic static class
public static class LinqHelper
{
}

The answer was surprisingly simple. I had to add a Content-Type header in the POST request with a value of application/json. Without this header Jersey did not know what to do with the request body (in spite of the @Consumes(MediaType.APPLICATION_JSON) annotation)!

Named export

In TS you can export with the export keyword. It then can be imported via import {name} from "./mydir";. This is called a named export. A file can export multiple named exports. Also the names of the imports have to match the exports. For example:

// foo.js file
export class foo{}
export class bar{}

// main.js file in same dir
import {foo, bar} from "./foo";

The following alternative syntax is also valid:

// foo.js file
function foo() {};
function bar() {};
export {foo, bar};

// main.js file in same dir
import {foo, bar} from './foo'

Default export

We can also use a default export. There can only be one default export per file. When importing a default export we omit the square brackets in the import statement. We can also choose our own name for our import.

// foo.js file
export default class foo{}

// main.js file in same directory
import abc from "./foo";

It's just JavaScript

Modules and their associated keyword like import, export, and export default are JavaScript constructs, not typescript. However typescript added the exporting and importing of interfaces and type aliases to it.

You would need to have an instance of ClassA within ClassB or have ClassB inherit ClassA

class ClassA {
    public function getName() {
      echo $this->name;
    }
}

class ClassB extends ClassA {
    public function getName() {
      parent::getName();
    }
}

Without inheritance or an instance method, you'd need ClassA to have a static method

class ClassA {
  public static function getName() {
    echo "Rawkode";
  }
}

--- other file ---

echo ClassA::getName();

If you're just looking to call the method from an instance of the class:

class ClassA {
  public function getName() {
    echo "Rawkode";
  }
}

--- other file ---

$a = new ClassA();
echo $a->getName();

Regardless of the solution you choose, require 'ClassA.php is needed.

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

You can use

 =Format(Fields!myField.Value,"F2") 

If is a package then you can get the source for that with:

    select text from all_source where name = 'PADCAMPAIGN' 
    and type = 'PACKAGE BODY'
    order by line;

Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.

Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use

    select text from all_source where name = 'pAdCampaign' 
    and type = 'PACKAGE BODY'
    order by line;

Every WP install has a readme.html file.

So just type www.yourdomain.com/readme.html

I faced this problem when building my project with Jenkins. First, it could not find ant.bat, which was fixed by adding the path to ant.bat to the system environment variable path. Then ant could not find the jdk directory. This was fixed by right-clicking on my computer > properties > advanced > environment variables and creating a new environment variable called JAVA_HOME and assigning it a value of C:\Program Files\Java\jdk1.7.0_21. Don't create this environment variable in User Variables. Create it under System Variables only.
In both cases, I had to restart the system.

In the manifest you can add:

android:noHistory="true"

<activity
android:name=".ActivityName"
android:noHistory="true" />

You can also call

finish()

immediately after calling startActivity(..)

You could pass somevar by value(not by reference) via a javascript feature known as closure:

var someVar='origin';
func = function(v){
    console.log(v);
}
document.addEventListener('click',function(someVar){
   return function(){func(someVar)}
}(someVar));
someVar='changed'

Or you could write a common wrap function such as wrapEventCallback:

function wrapEventCallback(callback){
    var args = Array.prototype.slice.call(arguments, 1);
    return function(e){
        callback.apply(this, args)
    }
}
var someVar='origin';
func = function(v){
    console.log(v);
}
document.addEventListener('click',wrapEventCallback(func,someVar))
someVar='changed'

Here wrapEventCallback(func,var1,var2) is like:

func.bind(null, var1,var2)

import java.io.FileInputStream; import java.io.ByteArrayOutputStream;

public class FileHashStream { // write a new method that will provide a new Byte array, and where this generally reads from an input stream

public static byte[] read(InputStream is) throws Exception
{
    String path = /* type in the absolute path for the 'commons-codec-1.10-bin.zip' */;

    // must need a Byte buffer

    byte[] buf = new byte[1024 * 16]

    // we will use 16 kilobytes

    int len = 0;

    // we need a new input stream

    FileInputStream is = new FileInputStream(path);

    // use the buffer to update our "MessageDigest" instance

    while(true)
    {
        len = is.read(buf);
        if(len < 0) break;
        md.update(buf, 0, len);
    }

    // close the input stream

    is.close();

    // call the "digest" method for obtaining the final hash-result

    byte[] ret = md.digest();

    System.out.println("Length of Hash: " + ret.length);

    for(byte b : ret)
    {
        System.out.println(b + ", ");
    }

    String compare = "49276d206b696c6c696e6720796f757220627261696e206c696b65206120706f69736f6e6f7573206d757368726f6f6d";

    String verification = Hex.encodeHexString(ret);

    System.out.println();

    System.out.println("===")

    System.out.println(verification);

    System.out.println("Equals? " + verification.equals(compare));

}

}

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

Use column selection. Column selection is one of the unique features of Sublime2; it is used to give you multiple matched cursors (tutorial here). To get multiple cursors, do one of the following:

Mouse:

• Hold down the shift (Windows/Linux) or option key (Mac) while selecting a region with the mouse.

• Clicking middle mouse button (or scroll) will select as a column also.

Keyboard:

• Select the desired region.
• Type control+shift+L (Windows/Linux) or command+shift+L (Mac)

You now have multiple lines selected, so you could type a quotation mark at the beginning and end of each line. It would be better to take advantage of Sublime's capabilities, and just type ". When you do this, Sublime automatically quotes the selected text.

Type esc to exit multiple cursor mode.

without looking at your input file, only a guess

awk '{$1=$1}1' OFS=","

redirect to another file and rename as needed

try c_x freeze it can create a good standalone

The Google style guide contains an excellent Python style guide. It includes conventions for readable docstring syntax that offers better guidance than PEP-257. For example:

def square_root(n):
    """Calculate the square root of a number.

    Args:
        n: the number to get the square root of.
    Returns:
        the square root of n.
    Raises:
        TypeError: if n is not a number.
        ValueError: if n is negative.

    """
    pass

I like to extend this to also include type information in the arguments, as described in this Sphinx documentation tutorial. For example:

def add_value(self, value):
    """Add a new value.

       Args:
           value (str): the value to add.
    """
    pass

Check for extra commas in your JSON response. If the last element of an array has a comma, this will break in IE

$('#tblCart tr').click(function () {
        var tr_id = $(this).attr('id'); 
        alert(tr_id );
    });



<table class="table table-striped table-bordered table-hover" id="tblCart" cellspacing="0" align="center" >
                <tr>
                    <th>

                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Price.PriceAmount)
                    </th>
                    <th>

                    </th>
                    <th>
                        @Html.DisplayNameFor(model => model.Subtotal)

                </tr>

               @if (cart != null)
               {
                   foreach (var vm in cart)
                   {
                    <tr id="@vm.Id">
                        <td>

                    </tr>  
                   }
               }
            </table>

For anyone who is looking for a solution to this problem in GitBook. This is how I made it work (in GitBook). You need to tag your header explicitly, like this:

# My Anchored Heading {#my-anchor}

Then link to this anchor like this

[link to my anchored heading](#my-anchor)

Solution, and additional examples, may be found here: https://seadude.gitbooks.io/learn-gitbook/

In Python...

class X( object ):
    def __init__( self ):
        self.attribute
    def getAttr( self ):
        return self.attribute
    def setAttr( self, value ):
        self.attribute= value
    property_name= property( getAttr, setAttr )

A property is a single attribute-like name that wraps a collection of setter, getter (and deleter) functions.

An attribute is usually a single object within another object.

Having said that, however, Python gives you methods like __getattr__ which allow you extend the definition of "attribute".

Bottom Line - they're almost synonymous. Python makes a technical distinction in how they're implemented.

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.

To keep the code clean I have created the following extension method for anyone using Angular 7 and below. This can also be used to extend any other functionality of Reactive Forms.

import { FormArray } from '@angular/forms';

declare module '@angular/forms/src/model' {
  interface FormArray {
    clearArray: () => FormArray;
  }
}

FormArray.prototype.clearArray = function () {
  const _self = this as FormArray;
  _self.controls = [];
  _self.setValue([]);
  _self.updateValueAndValidity();
  return _self;
}

Lots of others have already advised you to rethink your code to make it more testable - good advice and usually simpler than what I'm about to suggest.

If you can't change the code to make it more testable, PowerMock: https://code.google.com/p/powermock/

PowerMock extends Mockito (so you don't have to learn a new mock framework), providing additional functionality. This includes the ability to have a constructor return a mock. Powerful, but a little complicated - so use it judiciously.

You use a different Mock runner. And you need to prepare the class that is going to invoke the constructor. (Note that this is a common gotcha - prepare the class that calls the constructor, not the constructed class)

@RunWith(PowerMockRunner.class)
@PrepareForTest({First.class})

Then in your test set-up, you can use the whenNew method to have the constructor return a mock

whenNew(Second.class).withAnyArguments().thenReturn(mock(Second.class));

Find .xcodeproj file and open it with a text editor

Find fields below and make them like this

CODE_SIGN_IDENTITY = "iPhone Developer"; "CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Developer";

PROVISIONING_PROFILE = "";

PROVISIONING_PROFILE_SPECIFIER = "";

See DateDiff:

DECLARE @startdate date = '2011/1/1'
DECLARE @enddate date = '2011/3/1'
SELECT DATEDIFF(day, @startdate, @enddate)

This is an article about your problem. Adding a thousands-seperator is not built in to JavaScript, so you'll have to write your own function like this (example taken from the linked page):

function addSeperator(nStr){
  nStr += '';
  x = nStr.split('.');
  x1 = x[0];
  x2 = x.length > 1 ? '.' + x[1] : '';
  var rgx = /(\d+)(\d{3})/;
  while (rgx.test(x1)) {
    x1 = x1.replace(rgx, '$1' + ',' + '$2');
  }
  return x1 + x2;
}

I prefer to rely on libraries whenever possible for this sort of operation. This makes me less likely to accidentally omit an important step (like mistake wolfsnipes made above). Some libraries are suggested above, but my favorite for this kind of thing is Google Guava. Guava has a class called Files which works nicely for this task:

// This is where the file goes.

The generic answer provided by "Joel Coehoorn" is good.

But, this is another way without using those GetConverter... or try/catch blocks... (i'm not sure but this may have better performance in some cases):

public static class StrToNumberExtensions
{
    public static short ToShort(this string s, short defaultValue = 0) => short.TryParse(s, out var v) ? v : defaultValue;
    public static int ToInt(this string s, int defaultValue = 0) => int.TryParse(s, out var v) ? v : defaultValue;
    public static long ToLong(this string s, long defaultValue = 0) => long.TryParse(s, out var v) ? v : defaultValue;
    public static decimal ToDecimal(this string s, decimal defaultValue = 0) => decimal.TryParse(s, out var v) ? v : defaultValue;
    public static float ToFloat(this string s, float defaultValue = 0) => float.TryParse(s, out var v) ? v : defaultValue;
    public static double ToDouble(this string s, double defaultValue = 0) => double.TryParse(s, out var v) ? v : defaultValue;

    public static short? ToshortNullable(this string s, short? defaultValue = null) => short.TryParse(s, out var v) ? v : defaultValue;
    public static int? ToIntNullable(this string s, int? defaultValue = null) => int.TryParse(s, out var v) ? v : defaultValue;
    public static long? ToLongNullable(this string s, long? defaultValue = null) => long.TryParse(s, out var v) ? v : defaultValue;
    public static decimal? ToDecimalNullable(this string s, decimal? defaultValue = null) => decimal.TryParse(s, out var v) ? v : defaultValue;
    public static float? ToFloatNullable(this string s, float? defaultValue = null) => float.TryParse(s, out var v) ? v : defaultValue;
    public static double? ToDoubleNullable(this string s, double? defaultValue = null) => double.TryParse(s, out var v) ? v : defaultValue;
}

Usage is as following:

var x1 = "123".ToInt(); //123
var x2 = "abc".ToInt(); //0
var x3 = "abc".ToIntNullable(); // (int?)null 
int x4 = ((string)null).ToInt(-1); // -1
int x5 = "abc".ToInt(-1); // -1

var y = "19.50".ToDecimal(); //19.50

var z1 = "invalid number string".ToDoubleNullable(); // (double?)null
var z2 = "invalid number string".ToDoubleNullable(0); // (double?)0

In latest IntelliJ versions, you should run it from Analyze->Run Inspection By Name:

Than, pick Unused declaration:

And finally, uncheck the Include test sources:

The div elements are block elements, so by default they take upp the full available width.

One way is to turn them into inline elements:

.label, .text { display: inline; }

This will have the same effect as using span elements instead of div elements.

Another way is to float the elements:

.label, .text { float: left; }

This will change how the width of the elements is decided, so that thwy will only be as wide as their content. It will also make the elements float beside each other, similar to how images flow beside each other.

You can also consider changing the elements. The div element is intended for document divisions, I usually use a label and a span element for a construct like this:

<label>My Label:</label>
<span>My text</span>

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

This thread is old, but I just recently stumbled over the defaultProxy issue and maybe it helps others.

I used the config setting as Andrew suggested. When deploying it, my customer got an error saying, there weren't sufficient rights to set the configuration 'defaultProxy'.

Not knowing why I do not have the right to set this configuration and what to do about it, I just removed it and it still worked. So it seems that in VS2013 this issue is fixed.

And while we're at it:

    WebRequest.DefaultWebProxy.Credentials = new NetworkCredential("ProxyUsername", "ProxyPassword");

uses the default proxy with your credentials. If you want to force not using a proxy just set the DefaultWebProxy to null (though I don't know if one wants that).

Yes, it is called Inline CSS, Here you styling the div using some height, width, and background.

Here the example:

<div style="width:50px;height:50px;background color:red">

You can achieve same using Internal or External CSS

2.Internal CSS:

  <head>
    <style>
    div {
    height:50px;
    width:50px;
    background-color:red;
    foreground-color:white;
    }
    </style>
  </head>
  <body>
    <div></div>
  </body>

3.External CSS:

<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div></div>
</body>

style.css /external css file/

 div {
        height:50px;
        width:50px;
        background-color:red;
    }

It sounds like you want something like the Perl chomp() function.

That's trivial to do in Python:

def chomp(s):
    return s[:-1] if s.endswith('\n') else s

... assuming you're using Python 2.6 or later. Otherwise just use the slightly more verbose:

def chomp(s):
    if s.endwith('\n'):
        return s[:-1]
    else:
        return s

If you want to remove all new lines from the end of a string (in the odd case where one might have multiple trailing newlines for some reason):

def chomps(s):
    return s.rstrip('\n')

Obviously you should never see such a string returned by any normal Python file object's readline() nor readlines() methods.

I've seen people blindly remove the last characters (using s[:-1] slicing) from the results of file readline() and similar functions. This is a bad idea because it can lead to an error on the last line of the file (in the case where a file ends with anything other than a newline).

At first you might be lulled into a false sense of security when blindly stripping final characters off lines you've read. If you use a normal text editor to create your test suite files you'll have a newline silently added to the end of the last line by most of them. To create a valid test file use code something like:

f = open('sometest.txt', 'w')
f.write('some text')
f.close()

... and then if you re-open that file and use the readline() or readlines() file methods on it you'll find that the text is read without the trailing newline.

This failure to account for text files ending in non-newline characters has plagued many UNIX utilities and scripting languages for many years. It's a stupid corner base bug that creeps into code just often enough to be a pest but not often enough for people to learn from it. We could argue that "text" files without the ultimate newline are "corrupt" or non-standard; and that may be valid for some programming specifications.

However, it's all too easy to ignore corner cases in our coding and have that ignorance bite people who are depending on your code later. As my wife says: when it comes to programming ... practice safe hex!

Based on my highly scientific and accurate experiment, it tops out on my machine well before 1,000,000,000 characters. (I'm still running the code below to get a better pinpoint).

UPDATE: After a few hours, I've given up. Final results: Can go a lot bigger than 100,000,000 characters, instantly given System.OutOfMemoryException at 1,000,000,000 characters.

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

'\r' is the carriage return character. The main times it would be useful are:

1. When reading text in binary mode, or which may come from a foreign OS, you'll find (and probably want to discard) it due to CR/LF line-endings from Windows-format text files.

2. When writing to an interactive terminal on stdout or stderr, '\r' can be used to move the cursor back to the beginning of the line, to overwrite it with new contents. This makes a nice primitive progress indicator.

The example code in your post is definitely a wrong way to use '\r'. It assumes a carriage return will precede the newline character at the end of a line entered, which is non-portable and only true on Windows. Instead the code should look for '\n' (newline), and discard any carriage return it finds before the newline. Or, it could use text mode and have the C library handle the translation (but text mode is ugly and probably should not be used).

In my previous implementation I stored a list of child Fragments to be able to access them later, but this turned out to be a wrong implementation causing huge memory leaks.

I end up using instantiateItem(...) method to get current Fragment:

val currentFragment = adapter?.instantiateItem(viewPager, viewPager.currentItem)

Or to get any other Fragment on position:

val position = 0
val myFirstFragment: MyFragment? = (adapter?.instantiateItem(viewPager, position) as? MyFragment)

From documentation:

Create the page for the given position. The adapter is responsible for adding the view to the container given here, although it only must ensure this is done by the time it returns from finishUpdate(ViewGroup).

Create a new Item and go to the last you'll find option to copy from existing, just write your current job name and you will have clone of that project to work with.

I think the easiest route is to include the jQuery javascript library in your webpages, then use JSON as format to pass data between the two.

In your HTML pages, you can request data from the PHP scripts like this:

$.getJSON('http://foo/bar.php', {'num1': 12, 'num2': 27}, function(e) {
    alert('Result from PHP: ' + e.result);
});

In bar.php you can do this:

$num1 = $_GET['num1'];
$num2 = $_GET['num2'];
echo json_encode(array("result" => $num1 * $num2));

This is what's usually called AJAX, and it is useful to give web pages a more dynamic and desktop-like feel (you don't have to refresh the entire page to communicate with PHP).

Other techniques are simpler. As others have suggested, you can simply generate the variable data from your PHP script:

$foo = 123;
echo "<script type=\"text/javascript\">\n";
echo "var foo = ${foo};\n";
echo "alert('value is:' + foo);\n";
echo "</script>\n";

Most web pages nowadays use a combination of the two.

Is this what you are trying to do?

# Our data
text <- c("F.US.CLE.V13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
"F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
"F.US.DL.U13", "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.Z13", "F.US.DL.Z13"
)

#  Split into individual elements by the '.' character
#  Remember to escape it, because '.' by itself matches any single character
elems <- unlist( strsplit( text , "\\." ) )

#  We know the dataframe should have 4 columns, so make a matrix
m <- matrix( elems , ncol = 4 , byrow = TRUE )

#  Coerce to data.frame - head() is just to illustrate the top portion
head( as.data.frame( m ) )
#  V1 V2  V3  V4
#1  F US CLE V13
#2  F US CA6 U13
#3  F US CA6 U13
#4  F US CA6 U13
#5  F US CA6 U13
#6  F US CA6 U13

I don't think you properly understood what you read. If it gets compiled to the correct type, then there is no difference. When I do this:

var i = 42;

The compiler knows it's an int, and generate code as if I had written

int i = 42;

As the post you linked to says, it gets compiled to the same type. It's not a runtime check or anything else requiring extra code. The compiler just figures out what the type must be, and uses that.

You can use:

print(df[df['Value']==df['Value'].max()])

Here is my solution. Lots of solution already posted before me. But I love to share my view here.

const mainStr = 'str1,str2,str3,str4';

const commaAndStringCounter = (str) => {
  const commas = [...str].filter(letter => letter === ',').length;
  const numOfStr = str.split(',').length;

  return `Commas: ${commas}, String: ${numOfStr}`;
}

// Run the code
console.log(commaAndStringCounter(mainStr)); // Output: Commas: 3, String: 4
