To take input " long int " and output " long int " in C is :

long int n;
scanf("%ld", &n);
printf("%ld", n);

To take input " long long int " and output " long long int " in C is :

long long int n;
scanf("%lld", &n);
printf("%lld", n);

Hope you've cleared..

It's very simple.

You can call it from anywhere in APP.

$out = new \Symfony\Component\Console\Output\ConsoleOutput();
$out->writeln("Hello from Terminal");

You may find it more readable to reverse your logic and use an else statement with an empty if.

if($some_variable === 'uk' || $another_variable === 'in'){}

else {
    // This occurs when neither of the above are true
}

Since the release PHP 7.1+, is not more possible to assign a value for an array as follow:

$foo = ""; 
$foo['key'] = $foo2; 

because as of PHP 7.1.0, applying the empty index operator on a string throws a fatal error. Formerly, the string was silently converted to an array.

It's all in your error message - seems like unclean shutdown was detected. See http://docs.mongodb.org/manual/tutorial/recover-data-following-unexpected-shutdown/ for detailed information.

In my expirience, usually it helps to run mongod.exe with --repair option ro repair DB.

Just use

If @searchType is null means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR @SearchType is NULL

If @searchType is an empty string means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR @SearchType = ''

If @searchType is null or an empty string means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR Coalesce(@SearchType,'') = ''

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

When you double-quote a path, you're stopping the tilde expansion. So there are a few ways to do this:

cd ~/"My Code"
cd ~/'My Code'

The tilde is not quoted here, so tilde expansion will still be run.

cd "$HOME/My Code"

You can expand environment variables inside double-quoted strings; this is basically what the tilde expansion is doing

cd ~/My\ Code

You can also escape special characters (such as space) with a backslash.

Split on tab, but then remove all blank matches.

text = "hi\tthere\t\t\tmy main man"
print [splits for splits in text.split("\t") if splits is not ""]

Outputs:

['hi', 'there', 'my main man']

// Parent layout
LinearLayout parentLayout = (LinearLayout)findViewById(R.id.layout);

// Layout inflater
LayoutInflater layoutInflater = getLayoutInflater();
View view;

for (int i = 1; i < 101; i++){
    // Add the text layout to the parent layout
    view = layoutInflater.inflate(R.layout.text_layout, parentLayout, false);

    // In order to get the view we have to use the new view with text_layout in it
    TextView textView = (TextView)view.findViewById(R.id.text);
    textView.setText("Row " + i);

    // Add the text view to the parent layout
    parentLayout.addView(textView);
}

I use max function:

max(None, '')  #Returns blank
max("Hello",'') #Returns Hello

Works like a charm ;) Just put your string in the first parameter of the function.

Height and width are zero because view has not been created by the time you are requesting it's height and width . One simplest solution is

view.post(new Runnable() {
        @Override
        public void run() {
            view.getHeight(); //height is ready
            view.getWidth(); //width is ready
        }
    });

This method is good as compared to other methods as it is short and crisp.

look at it is informative [Qualified identifiers

A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.

The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

Simple code to check pointer aliasing:

int main () {
    int a = 10, b = 20;
    int *p1, *p2, *p3, *p4;

    p1 = &a;
    p2 = &a;
    if(p1 == p2){
        std::cout<<"p1 and p2 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p1 and p2 do not alias each other"<<std::endl;
    }
    //------------------------
    p3 = &a;
    p4 = &b;
    if(p3 == p4){
        std::cout<<"p3 and p4 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p3 and p4 do not alias each other"<<std::endl;
    }
    return 0;
}

Output:

p1 and p2 alias each other
p3 and p4 do not alias each other

Solved the problem, when moved the folder with the image in src folder. Then I turned to the image (project created through "create-react-app")

update YourTable
    set YourColumn = replace(YourColumn, '@domain2', '@domain1')
    where charindex('@domain2', YourColumn) <> 0

Since an array has a fixed size that is allocated when created, your only option is to create a new array without the element you want to remove.

If the element you want to remove is the last array item, this becomes easy to implement using Arrays.copy:

int a[] = { 1, 2, 3};
a = Arrays.copyOf(a, 2);

After running the above code, a will now point to a new array containing only 1, 2.

Otherwise if the element you want to delete is not the last one, you need to create a new array at size-1 and copy all the items to it except the one you want to delete.

The approach above is not efficient. If you need to manage a mutable list of items in memory, better use a List. Specifically LinkedList will remove an item from the list in O(1) (fastest theoretically possible).

Define a function like:

fetchRestaurants(callback) {
    fetch(`http://www.restaurants.com`)
       .then(response => response.json())
       .then(json => callback(null, json.restaurants))
       .catch(error => callback(error, null))
}

Then use it like this:

fetchRestaurants((error, restaurants) => {
    if (error) 
        console.log(error)
    else 
        console.log(restaurants[0])

});

SecurityContext will be deprecated in Symfony 3.0

Prior to Symfony 2.6 you would use SecurityContext.
SecurityContext will be deprecated in Symfony 3.0 in favour of the AuthorizationChecker.

For Symfony 2.6+ & Symfony 3.0 use AuthorizationChecker.

Symfony 2.6 (and below)

// Get our Security Context Object - [deprecated in 3.0]
$security_context = $this->get('security.context');
# e.g: $security_context->isGranted('ROLE_ADMIN');

// Get our Token (representing the currently logged in user)
$security_token = $security_context->getToken();
# e.g: $security_token->getUser();
# e.g: $security_token->isAuthenticated();
# [Careful]             ^ "Anonymous users are technically authenticated"

// Get our user from that security_token
$user = $security_token->getUser();
# e.g: $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();

// Check for Roles on the $security_context
$isRoleAdmin = $security_context->isGranted('ROLE_ADMIN');
# e.g: (bool) true/false

Symfony 3.0+ (and from Symfony 2.6+)

security.context becomes security.authorization_checker.
We now get our token from security.token_storage instead of the security.context

// [New 3.0] Get our "authorization_checker" Object
$auth_checker = $this->get('security.authorization_checker');
# e.g: $auth_checker->isGranted('ROLE_ADMIN');

// Get our Token (representing the currently logged in user)
// [New 3.0] Get the `token_storage` object (instead of calling upon `security.context`)
$token = $this->get('security.token_storage')->getToken();
# e.g: $token->getUser();
# e.g: $token->isAuthenticated();
# [Careful]            ^ "Anonymous users are technically authenticated"

// Get our user from that token
$user = $token->getUser();
# e.g (w/ FOSUserBundle): $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();

// [New 3.0] Check for Roles on the $auth_checker
$isRoleAdmin = $auth_checker->isGranted('ROLE_ADMIN');
// e.g: (bool) true/false

How to do this in twig?: Symfony 2: How do I check if a user is not logged in inside a template?

This is what is recommended as the right solution:

The right solution (credits go to Dan, CommonsWare and NeTeInStEiN) Track visibility of your application by yourself using Activity.onPause, Activity.onResume methods. Store "visibility" status in some other class. Good choices are your own implementation of the Application or a Service (there are also a few variations of this solution if you'd like to check activity visibility from the service).

Example Implement custom Application class (note the isActivityVisible() static method):

public class MyApplication extends Application {

  public static boolean isActivityVisible() {
    return activityVisible;
  }  

  public static void activityResumed() {
    activityVisible = true;
  }

  public static void activityPaused() {
    activityVisible = false;
  }

  private static boolean activityVisible;
}

Register your application class in AndroidManifest.xml:

<application
    android:name="your.app.package.MyApplication"
    android:icon="@drawable/icon"
    android:label="@string/app_name" >

Add onPause and onResume to every Activity in the project (you may create a common ancestor for your Activities if you'd like to, but if your activity is already extended from MapActivity/ListActivity etc. you still need to write the following by hand):

@Override
protected void onResume() {
  super.onResume();
  MyApplication.activityResumed();
}

@Override
protected void onPause() {
  super.onPause();
  MyApplication.activityPaused();
}

In your finish() method, you want to use isActivityVisible() to check if the activity is visible or not. There you can also check if the user has selected an option or not. Continue when both conditions are met.

The source also mentions two wrong solutions...so avoid doing that.

Yes, you can use numpy for that.

import numpy as np
a = arange(3,dtype=float)

a[0] = np.nan
a[1] = np.inf
a[2] = -np.inf

a # is now [nan,inf,-inf]

np.isnan(a[0]) # True
np.isinf(a[1]) # True
np.isinf(a[2]) # True

Here is an example:

public class TextViewMarquee extends Activity {
    private TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv = (TextView) this.findViewById(R.id.mywidget);  
        tv.setSelected(true);  // Set focus to the textview
    }
}

The xml file with the textview:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView
        android:id="@+id/mywidget"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:singleLine="true"
        android:ellipsize="marquee"
        android:fadingEdge="horizontal"
        android:marqueeRepeatLimit="marquee_forever"
        android:scrollHorizontally="true"
        android:textColor="#ff4500"
        android:text="Simple application that shows how to use marquee, with a long text" />
</RelativeLayout>

Check out the implode() function as an alternative. This will convert the array into a list. The first param is how you want the items separated. Here I have used a comma with a space after it.

$invite = implode(', ', $_POST['invite']);
echo $invite;

Hi I know this was asked a while ago but I've just figured this out and it might help someone else. Not sure if this is exactly what you're looking for but this is how I call a stored proc and view the output using SQL Developer.
In SQL Developer when viewing the proc, right click and choose 'Run' or select Ctrl+F11 to bring up the Run PL/SQL window. This creates a template with the input and output params which you need to modify. My proc returns a sys_refcursor. The tricky part for me was declaring a row type that is exactly equivalent to the select stmt / sys_refcursor being returned by the proc:

DECLARE
  P_CAE_SEC_ID_N NUMBER;
  P_FM_SEC_CODE_C VARCHAR2(200);
  P_PAGE_INDEX NUMBER;
  P_PAGE_SIZE NUMBER;
  v_Return sys_refcursor;
  type t_row is record (CAE_SEC_ID NUMBER,FM_SEC_CODE VARCHAR2(7),rownum number, v_total_count number);
  v_rec t_row;

BEGIN
  P_CAE_SEC_ID_N := NULL;
  P_FM_SEC_CODE_C := NULL;
  P_PAGE_INDEX := 0;
  P_PAGE_SIZE := 25;

  CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
    P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
    P_FM_SEC_CODE_C => P_FM_SEC_CODE_C,
    P_PAGE_INDEX => P_PAGE_INDEX,
    P_PAGE_SIZE => P_PAGE_SIZE,
    P_FOF_SEC_REFCUR => v_Return
  );
  -- Modify the code to output the variable
  -- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
  loop
    fetch v_Return into v_rec;
    exit when v_Return%notfound;
    DBMS_OUTPUT.PUT_LINE('sec_id = ' || v_rec.CAE_SEC_ID || 'sec code = ' ||v_rec.FM_SEC_CODE);
  end loop;

END;

This problem can generally occur when you do not enable two step verification for the gmail account (which can be done here) you are using to send an email. So first, enable two step verification, you can find plenty of resources for enabling two step verification. After you enable it, then you have to create an app password. And use the app password in your .env file. When you are done with it, your .env file will look something like.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>
MAIL_ENCRYPTION=tls

and your mail.php

<?php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.gmail.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => ['address' => '<<your email>>', 'name' => '<<any name>>'],
    'encryption' => env('MAIL_ENCRYPTION', 'tls'),
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,

];

After doing so, run php artisan config:cache and php artisan config:clear, then check, email should work.

The second way isn't valid XML; did you mean <numbers>[3,2,1]</numbers>?

If so, then the first one is preferred because all you need to get the array elements is some XML manipulation. On the second one you first need to get the value of the <numbers> element via XML manipulation, then somehow parse the [3,2,1] text using something else.

Or if you really want some compact format, you can consider using JSON (which "natively" supports arrays). But that depends on your application requirements.

I think you may be getting tripped up on the sheet protection. I streamlined your code a little and am explicitly setting references to the workbook and worksheet objects. In your example, you explicitly refer to the workbook and sheet when you're setting the TxtRng object, but not when you unprotect the sheet.

Try this:

Sub varchanger()

    Dim wb As Workbook
    Dim ws As Worksheet
    Dim TxtRng  As Range

    Set wb = ActiveWorkbook
    Set ws = wb.Sheets("Sheet1")
    'or ws.Unprotect Password:="yourpass"
    ws.Unprotect

    Set TxtRng = ws.Range("A1")
    TxtRng.Value = "SubTotal"
    'http://stackoverflow.com/questions/8253776/worksheet-protection-set-using-ws-protect-but-doesnt-unprotect-using-the-menu
    ' or ws.Protect Password:="yourpass"
    ws.Protect

End Sub

If I run the sub with ws.Unprotect commented out, I get a run-time error 1004. (Assuming I've protected the sheet and have the range locked.) Uncommenting the line allows the code to run fine.

NOTES:

1. I'm re-setting sheet protection after writing to the range. I'm assuming you want to do this if you had the sheet protected in the first place. If you are re-setting protection later after further processing, you'll need to remove that line.
2. I removed the error handler. The Excel error message gives you a lot more detail than Err.number. You can put it back in once you get your code working and display whatever you want. Obviously you can use Err.Description as well.
3. The Cells(1, 1) notation can cause a huge amount of grief. Be careful using it. Range("A1") is a lot easier for humans to parse and tends to prevent forehead-slapping mistakes.

You have missed one style ".btn-primary:active:focus" which causes that still during btn click default bootstrap color show up for a second. This works in my code:

.btn-primary, .btn-primary:hover, .btn-primary:active, .btn-primary:visited, .btn-primary:focus, .btn-primary:active:focus {
background-color: #8064A2;}

String extends Object, which means an Object. Object o = a; If you really want to get as Object, you may do like below.

String s = "Hi";

Object a =s;

I had the same problem on Visual Studio Code. For various reasons several python versions are installed on my computer. I was thus able to easily solve the problem by switching python interpreter.

If like me you have several versions of python on you machine, in Visual Studio Code, you can easily change the interpreter by clicking on the bottom left corner where it says Python...

I think you can do something like this..

EDIT : Changed the code to work irrespective of the caret postion

First part of the code is to get the caret position.

Ref: How to get the caret column (not pixels) position in a textarea, in characters, from the start?

function getCaret(el) { 
    if (el.selectionStart) { 
        return el.selectionStart; 
    } else if (document.selection) { 
        el.focus();
        var r = document.selection.createRange(); 
        if (r == null) { 
            return 0;
        }
        var re = el.createTextRange(), rc = re.duplicate();
        re.moveToBookmark(r.getBookmark());
        rc.setEndPoint('EndToStart', re);
        return rc.text.length;
    }  
    return 0; 
}

And then replacing the textarea value accordingly when Shift + Enter together , submit the form if Enter is pressed alone.

$('textarea').keyup(function (event) {
    if (event.keyCode == 13) {
        var content = this.value;  
        var caret = getCaret(this);          
        if(event.shiftKey){
            this.value = content.substring(0, caret - 1) + "\n" + content.substring(caret, content.length);
            event.stopPropagation();
        } else {
            this.value = content.substring(0, caret - 1) + content.substring(caret, content.length);
            $('form').submit();
        }
    }
});

Here is a demo

In Laravel 8 the way routes are specified has changed:

Route::resource('homes', HomeController::class)->names('home.index');

The error message means that it cannot locate your python executable or binary.

In many cases, it's installed at c:\python27. if it's not installed yet, you can install it with npm install --global windows-build-tools, which will only work if it hasn't been installed yet.

Adding it to the environment variables does not always work. A better alternative, is to just set it in the npm config.

npm config set python c:\python27\python.exe

Not a for each exactly, but you can do nested SQL

SELECT 
    distinct a.ID, 
    a.col2, 
    (SELECT 
        SUM(b.size) 
    FROM 
        tableb b 
    WHERE 
        b.id = a.col3)
FROM
    tablea a

If you want exactly one byte, uint8_t defined in cstdint would be the most expressive.

This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive. (Your code tries to reused the connection just as the server is closing it because it has been idle for too long.) You should basically just retry the operation over a new connection. (I'm surprised your library doesn't do this automatically.)

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

I've tried different cases and only when owner was set to nginx (chown -R nginx:nginx "/var/www/myfolder") - it started to work as expected.

I wrote an informative blog article about this topic: How to Extract IPv4 and IPv6 IP Addresses from Plain Text Using Regex.

In the article there's a detailed guide of the most common different patterns for IPs, often required to be extracted and isolated from plain text using regular expressions.
This guide is based on CodVerter's IP Extractor source code tool for handling IP addresses extraction and detection when necessary.

If you wish to validate and capture IPv4 Address this pattern can do the job:

\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b

or to validate and capture IPv4 Address with Prefix ("slash notation"):

\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?/[0-9]{1,2})\b

or to capture subnet mask or wildcard mask:

(255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)

or to filter out subnet mask addresses you do it with regex negative lookahead:

\b((?!(255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)))(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b

For IPv6 validation you can go to the article link I have added at the top of this answer.
Here is an example for capturing all the common patterns (taken from CodVerter`s IP Extractor Help Sample):

If you wish you can test the IPv4 regex here.

If you want to add a column to your table which is automatically updated to half of some other column, you can do that with a trigger.

But I think the already proposed answer are a better way to do this.

Dry coded trigger :

CREATE TRIGGER halfcolumn_insert AFTER INSERT ON table
  FOR EACH ROW BEGIN
    UPDATE table SET calculated = value / 2 WHERE id = NEW.id;
  END;
CREATE TRIGGER halfcolumn_update AFTER UPDATE ON table
  FOR EACH ROW BEGIN
    UPDATE table SET calculated = value / 2 WHERE id = NEW.id;
  END;

I don't think you can make only one trigger, since the event we must respond to are different.

Give this a try:

html, body,_x000D_
#left, #right {_x000D_
  height: 100%_x000D_
}_x000D_
_x000D_
#left {_x000D_
  float: left;_x000D_
  width: 25%;_x000D_
}_x000D_
#right {_x000D_
  width: 75%;_x000D_
}

<html>_x000D_
  <body>_x000D_
    <div id="left">_x000D_
      Content_x000D_
    </div>_x000D_
    <div id="right">_x000D_
      Content_x000D_
    </div>_x000D_
  </body>_x000D_
</html>

In ASP.NET web api 2 , CORS support has been added . Please check the link [ http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api ]

Have a look at the mainpage command.

Also, have a look this answer to another thread: How to include custom files in Doxygen. It states that there are three extensions which doxygen classes as additional documentation files: .dox, .txt and .doc. Files with these extensions do not appear in the file index but can be used to include additional information into your final documentation - very useful for documentation that is necessary but that is not really appropriate to include with your source code (for example, an FAQ)

So I would recommend having a mainpage.dox (or similarly named) file in your project directory to introduce you SDK. Note that inside this file you need to put one or more C/C++ style comment blocks.

This is useful to check the status of autocommit;

select @@autocommit;

If you are looking to do an exact match, use the following syntax: (param)?.

Eg.

<Route path={`my/(exact)?/path`} component={MyComponent} />

The nice thing about this is that you'll have props.match to play with, and you don't need to worry about checking the value of the optional parameter:

{ props: { match: { "0": "exact" } } }

Like this:

var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";

another solution is catching onClick event and for aggregate data to js function you can

.hmtl.erb

<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>

.js

// handle my-class click
$('a.my-class').on('click', function () {
  var link = $(this);
  var array = link.data('array');
});

I used numpy library and it works fine for me. Its just a single line and easy to understand. The input needs to be in a single size separated by space and the reshape converts the list into shape you want. Here (2,2) resizes the list of 4 elements into 2*2 matrix. Be careful in giving equal number of elements in the input corresponding to the dimension of the matrix.

import numpy as np
a=np.array(list(map(int,input().strip().split(' ')))).reshape(2,2)

print(a)

Input

array([[1, 2],
       [3, 4]])

Output

Or, you can install the GNU version of sed in your Mac, called gsed, and use it using the standard Linux syntax.

For that, install gsed using ports (if you don't have it, get it at http://www.macports.org/) by running sudo port install gsed. Then, you can run sed -i 's/old_link/new_link/g' *

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?

The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)

I also had same error but with codeigniter application. I changed

• my base URL in config.php to my localhost path

• in htaccess I changed RewriteBase /"my folder name in htdocs"

  and I able to login to my application.

Hope it might help.

I tested all the answers about this topic. And nothing worked here… but I found another solution.

Go to pom -> overview and add these to your properties:

Name: “maven.compiler.target” Value: “1.8”

and

Name: “maven.compiler.source” Value: “1.8”

Now do a maven update.

Based on KMier's answer, addresses the comment that this method poses a problem when the field to be padded is not a field, but the outcome of a (possibly complicated) function; the entire function has to be repeated.

Also, this allows for padding a field to the maximum length of its contents.

WITH
cte AS (
  SELECT 'foo' AS value_to_be_padded
  UNION SELECT 'foobar'
),
cte_max AS (
  SELECT MAX(LEN(value_to_be_padded)) AS max_len
)
SELECT
  CONCAT(SPACE(max_len - LEN(value_to_be_padded)), value_to_be_padded AS left_padded,
  CONCAT(value_to_be_padded, SPACE(max_len - LEN(value_to_be_padded)) AS right_padded;

There is no need to compute trigonometric functions. The simple code in C language is:

#include <math.h>
#define PIV2 M_PI+M_PI
#define C360 360.0000000000000000000
double difangrad(double x, double y)
{
double arg;

arg = fmod(y-x, PIV2);
if (arg < 0 )  arg  = arg + PIV2;
if (arg > M_PI) arg  = arg - PIV2;

return (-arg);
}
double difangdeg(double x, double y)
{
double arg;
arg = fmod(y-x, C360);
if (arg < 0 )  arg  = arg + C360;
if (arg > 180) arg  = arg - C360;
return (-arg);
}

let dif = a - b , in radians

dif = difangrad(a,b);

let dif = a - b , in degrees

dif = difangdeg(a,b);

difangdeg(180.000000 , -180.000000) = 0.000000
difangdeg(-180.000000 , 180.000000) = -0.000000
difangdeg(359.000000 , 1.000000) = -2.000000
difangdeg(1.000000 , 359.000000) = 2.000000

No sin, no cos, no tan,.... only geometry!!!!

Try this for Java programmatically:

myEditText(new InputFilter[] {new InputFilter.LengthFilter(CUSTOM_MAX_LEN)});

Another shorthand to (@maudulus's answer) to remove {maxFractionDigits} since it's optional.

You can use {{numberExample | number : '1.2'}}

Ink-Jet is right. More specifically, an .o (.obj) -- or object file is a single source file compiled in to machine code (I'm not sure if the "machine code" is the same or similar to an executable machine code). Ultimately, it's an intermediate between an executable program and plain-text source file.

The linker uses the o files to assemble the file executable.

Wikipedia may have more detailed information. I'm not sure how much info you'd like or need.

1. Use the 'jet' colormap for a transition between blue and red.
2. Use pcolor() with the vmin, vmax parameters.

2020 answer

CSS Filter works on all current browsers

To change any SVGs color

1. Add the SVG image using an <img> tag.

<img src="dotted-arrow.svg" class="filter-green"/>

2. To filter to a specific color, use the following Codepen(Click Here to open codepen) to convert a hex color code to a CSS filter:

For example, output for #00EE00 is

filter: invert(42%) sepia(93%) saturate(1352%) hue-rotate(87deg) brightness(119%) contrast(119%);

3. Add the CSS filter into this class.

    .filter-green{
        filter: invert(48%) sepia(79%) saturate(2476%) hue-rotate(86deg) brightness(118%) contrast(119%);
    }

I believe this is a more easy approach:

public class HibernateProxyTypeAdapter implements JsonSerializer<HibernateProxy>{

    public JsonElement serialize(HibernateProxy object_,
        Type type_,
        JsonSerializationContext context_) {
        return new GsonBuilder().create().toJsonTree(initializeAndUnproxy(object_)).getAsJsonObject();
        // that will convert enum object to its ordinal value and convert it to json element

    }

    public static <T> T initializeAndUnproxy(T entity) {
        if (entity == null) {
            throw new 
               NullPointerException("Entity passed for initialization is null");
        }

        Hibernate.initialize(entity);
        if (entity instanceof HibernateProxy) {
            entity = (T) ((HibernateProxy) entity).getHibernateLazyInitializer()
                    .getImplementation();
        }
        return entity;
    }
}

And then you will be able to call it like this:

Gson gson = new GsonBuilder()
        .registerTypeHierarchyAdapter(HibernateProxy.class, new HibernateProxyTypeAdapter())
        .create();

This way all the hibernate objects will be converted automatically.

You can use

text_Rate.setText(""+sdRate);

let dt = new Date('2013-03-10T02:00:00Z');
let dd = dt.getDate();
let mm = dt.getMonth() + 1;
let yyyy = dt.getFullYear();

if (dd<10) {
    dd = '0' + dd;
}
if (mm<10) {
    mm = '0' + mm;
}
return yyyy + '-' + mm + '-' + dd;

Simple method:

public boolean isBlank(String value) {
    return (value == null || value.equals("") || value.equals("null") || value.trim().equals(""));
}


public boolean isOnlyNumber(String value) {
    boolean ret = false;
    if (!isBlank(value)) {
        ret = value.matches("^[0-9]+$");
    }
    return ret;
}

This will do it with border-collapse

table{
    border-collapse:collapse;
}

One you convert your image to gray-scale you cannot got back. You have gone from three channel to one, when you try to go back all three numbers will be the same. So the short answer is no you cannot go back. The reason your backtorgb function this throwing that error is because it needs to be in the format:

CvtColor(input, output, CV_GRAY2BGR)

OpenCV use BGR not RGB, so if you fix the ordering it should work, though your image will still be gray.

What is actually the most robust and elegant automated solution for deserializing JSON to TypeScript runtime class instances?

Using property decorators with ReflectDecorators to record runtime-accessible type information that can be used during a deserialization process provides a surprisingly clean and widely adaptable approach, that also fits into existing code beautifully. It is also fully automatable, and works for nested objects as well.

An implementation of this idea is TypedJSON, which I created precisely for this task:

@JsonObject
class Foo {
    @JsonMember
    name: string;

    getName(): string { return this.name };
}

var foo = TypedJSON.parse('{"name": "John Doe"}', Foo);

foo instanceof Foo; // true
foo.getName(); // "John Doe"

You can do this go to Settings > Storage, clicking on the setting menu icon in the top right hand corner and selecting "USB computer connection". I then changed the storage mode to "Camera (PTP)". Done try re installing the driver from device manager.

I need context for using arrayAdapter IN fragment, when I was using getActivity error occurs but when i replace it with getContext it works for me

listView LV=getView().findViewById(R.id.listOFsensors);
LV.setAdapter(new ArrayAdapter<String>(getContext(),android.R.layout.simple_list_item_1 ,listSensorType));

As gluecks pointed out, no more SqlStudio.bin in Microsoft SQL Server Management Studio 18. I also found this UserSettings.xml in C:\Users\userName\AppData\Roaming\Microsoft\SQL Server Management Studio\18.0. But removing the <Element> containing the credential seems not working, it comes right back on the xml file, if I close and re-open it again.

Turns out, you need to close the SQL Server Management Studio first, then edit the UserSettings.xml file in your favorite editor, e.g. Visual Studio Code. I guess it's cached somewhere in SSMS besides this xml file?! And it's not on Control Panel\All Control Panel Items\Credential Manager\Windows Credentials.

Here is what I just did right now:

import java.sql.*;
import java.util.logging.Level;
import java.util.logging.Logger;

import com.sun.javafx.runtime.VersionInfo;  

public class ConnectToMySql {
public static ConnectBean dataBean = new ConnectBean();

public static void main(String args[]) {
    getData();
    }



public static void getData () {

    try {
        Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mynewpage", 
 "root", "root");
        
 // here mynewpage is database name, root is username and password
    
Statement stmt = con.createStatement();
        System.out.println("stmt  " + stmt);
        ResultSet rs = stmt.executeQuery("select * from carsData");
        System.out.println("rs  " + rs);
        int count = 1;
        while (rs.next()) {
            String vehicleType = rs.getString("VHCL_TYPE");
            System.out.println(count  +": " + vehicleType);
            count++;

        }

        con.close();
    } catch (Exception e) {
        Logger lgr = Logger.getLogger(VersionInfo.class.getName());
        lgr.log(Level.SEVERE, e.getMessage(), e);

        System.out.println(e.getMessage());
    }
    
    
}

}

The Above code will get you the first column of the table you have.

This is the table which you might need to create in your MySQL database

CREATE TABLE
carsData
(
    VHCL_TYPE CHARACTER(10) NOT NULL,
);

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

You can create a small class to hold the key and value, and then store objects of that class in the collection.

Class KeyValue:

Public key As String
Public value As String
Public Sub Init(k As String, v As String)
    key = k
    value = v
End Sub

Then to use it:

Public Sub Test()
    Dim col As Collection, kv As KeyValue
    Set col = New Collection
    Store col, "first key", "first string"
    Store col, "second key", "second string"
    Store col, "third key", "third string"
    For Each kv In col
        Debug.Print kv.key, kv.value
    Next kv
End Sub

Private Sub Store(col As Collection, k As String, v As String)
    If (Contains(col, k)) Then
        Set kv = col(k)
        kv.value = v
    Else
        Set kv = New KeyValue
        kv.Init k, v
        col.Add kv, k
    End If
End Sub

Private Function Contains(col As Collection, key As String) As Boolean
    On Error GoTo NotFound
    Dim itm As Object
    Set itm = col(key)
    Contains = True
MyExit:
    Exit Function
NotFound:
    Contains = False
    Resume MyExit
End Function

This is of course similar to the Dictionary suggestion, except without any external dependencies. The class can be made more complex as needed if you want to store more information.

try like below...

CASE 
WHEN currate.currentrate is null THEN 1
ELSE currate.currentrate
END as currentrate

Why would you do a while True and then break out of this loop while you can also just put your requirements in the while statement since all you want is to stop once you have the age?

age = None
while age is None:
    input_value = input("Please enter your age: ")
    try:
        # try and convert the string input to a number
        age = int(input_value)
    except ValueError:
        # tell the user off
        print("{input} is not a number, please enter a number only".format(input=input_value))
if age >= 18:
    print("You are able to vote in the United States!")
else:
    print("You are not able to vote in the United States.")

This would result in the following:

Please enter your age: *potato*
potato is not a number, please enter a number only
Please enter your age: *5*
You are not able to vote in the United States.

this will work since age will never have a value that will not make sense and the code follows the logic of your "business process"

01. Integer can be null. But int cannot be null.

Integer value1 = null; //OK

int value2 = null      //Error

02. Only can pass Wrapper Classes type values to any collection class.

(Wrapper Classes - Boolean,Character,Byte,Short,Integer,Long,Float,Double)

List<Integer> element = new ArrayList<>();
int valueInt = 10;
Integer  valueInteger = new Integer(value);
element.add(valueInteger);

But normally we add primitive values to collection class? Is point 02 correct?

List<Integer> element = new ArrayList<>();
element.add(5);

Yes 02 is correct, beacouse autoboxing.

Autoboxing is the automatic conversion that the java compiler makes between the primitive type and their corresponding wrapper class.

Then 5 convert as Integer value by autoboxing.

That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"

Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.

If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.

Update: In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4().

If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL:

uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')

Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:

uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')

A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.

Reading and printing the content of a text file (.txt) in Python3

Consider this as the content of text file with the name world.txt:

Hello World! This is an example of Content of the Text file we are about to read and print
using python!

First we will open this file by doing this:

file= open("world.txt", 'r')

Now we will get the content of file in a variable using .read() like this:

content_of_file= file.read()

Finally we will just print the content_of_file variable using print command.

print(content_of_file)

Output:

Hello World! This is an example of Content of the Text file we are about to read and print using python!

There is a very easy trick. Set padding of that div to a positive number and margin to negativ

#wrapper {
     background: url(xxx.jpeg);
     padding-left: 10px;
     margin-left: -10px;
}

You can get some information :

From Martin Fowler about Mock and Stub

Fake objects actually have working implementations, but usually take some shortcut which makes them not suitable for production

Stubs provide canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test. Stubs may also record information about calls, such as an email gateway stub that remembers the messages it 'sent', or maybe only how many messages it 'sent'.

Mocks are what we are talking about here: objects pre-programmed with expectations which form a specification of the calls they are expected to receive.

From xunitpattern:

Fake: We acquire or build a very lightweight implementation of the same functionality as provided by a component that the SUT depends on and instruct the SUT to use it instead of the real.

Stub : This implementation is configured to respond to calls from the SUT with the values (or exceptions) that will exercise the Untested Code (see Production Bugs on page X) within the SUT. A key indication for using a Test Stub is having Untested Code caused by the inability to control the indirect inputs of the SUT

Mock Object that implements the same interface as an object on which the SUT (System Under Test) depends. We can use a Mock Object as an observation point when we need to do Behavior Verification to avoid having an Untested Requirement (see Production Bugs on page X) caused by an inability to observe side-effects of invoking methods on the SUT.

Personally

I try to simplify by using : Mock and Stub. I use Mock when it's an object that returns a value that is set to the tested class. I use Stub to mimic an Interface or Abstract class to be tested. In fact, it doesn't really matter what you call it, they are all classes that aren't used in production, and are used as utility classes for testing.

Swift 3 For check Empty String best way

if !string.isEmpty{

// do stuff

}

Seems like there's a bug with applyFromArray right now that won't accept color, but this worked for me:

$objPHPExcel
    ->getActiveSheet()
    ->getStyle('A1')
    ->getFill()
    ->getStartColor()
    ->setRGB('FF0000');

If you want to add CSS on a:hover to not all the tag, but the some of the tag, best way to do that is by using class. Give the class to all the tags which you want to give style - see the example below.

<style>
a.change_hover_color:hover { 
    color: white !important;
}
</style>

<a class="change_hover_color">FACEBOOK</a>
<a class="change_hover_color">GOOGLE</a>

This worked for me:

mycomponent.component.ts:

action(event): void {
  event.stopPropagation();
}

mycomponent.component.html:

<button mat-icon-button (click)="action($event);false">Click me !<button/>

You could also try GSON library. Its quite powerful it can create JSON from collections, custom objects and works also vice versa. Its released under Apache Licence 2.0 so you can use it also commercially.

http://code.google.com/p/google-gson/

A reason for this problem (which is even harder to detect than the issue with char* str = "some string" - which others have explained) is when you are using constexpr.

constexpr char* str = "some string";

It seems that it would behave similar to const char* str, and so would not cause a warning, as it occurs before char*, but it instead behaves as char* const str.

Constant pointer, and pointer to a constant. The difference between const char* str, and char* const str can be explained as follows.

1. const char* str : Declare str to be a pointer to a const char. This means that the data to which this pointer is pointing to it constant. The pointer can be modified, but any attempt to modify the data would throw a compilation error.
   1. str++ ; : VALID. We are modifying the pointer, and not the data being pointed to.
   2. *str = 'a'; : INVALID. We are trying to modify the data being pointed to.
2. char* const str : Declare str to be a const pointer to char. This means that point is now constant, but the data being pointed too is not. The pointer cannot be modified but we can modify the data using the pointer.
   1. str++ ; : INVALID. We are trying to modify the pointer variable, which is a constant.
   2. *str = 'a'; : VALID. We are trying to modify the data being pointed to. In our case this will not cause a compilation error, but will cause a runtime error, as the string will most probably will go into a read only section of the compiled binary. This statement would make sense if we had dynamically allocated memory, eg. char* const str = new char[5];.
3. const char* const str : Declare str to be a const pointer to a const char. In this case we can neither modify the pointer, nor the data being pointed to.
   1. str++ ; : INVALID. We are trying to modify the pointer variable, which is a constant.
   2. *str = 'a'; : INVALID. We are trying to modify the data pointed by this pointer, which is also constant.

In my case the issue was that I was expecting constexpr char* str to behave as const char* str, and not char* const str, since visually it seems closer to the former.

Also, the warning generated for constexpr char* str = "some string" is slightly different from char* str = "some string".

1. Compiler warning for constexpr char* str = "some string": ISO C++11 does not allow conversion from string literal to 'char *const'
2. Compiler warning for char* str = "some string": ISO C++11 does not allow conversion from string literal to 'char *'.

Tip

You can use C gibberish ? English converter to convert C declarations to easily understandable English statements, and vice versa. This is a C only tool, and thus wont support things (like constexpr) which are exclusive to C++.

When you are using second approach you are initializing arraylist with its predefined values. Like generally we do ArrayList listofStrings = new ArrayList<>(); Let's say you have an array with values, now you want to convert this array into arraylist.

you need to first get the list from the array using Arrays utils. Because the ArrayList is concrete type that implement List interface. It is not guaranteed that method asList, will return this type of implementation.

List<String>  listofOptions = (List<String>) Arrays.asList(options);

then you can user constructoru of an arraylist to instantiate with predefined values.

ArrayList<String> arrlistofOptions = new ArrayList<String>(list);

So your second approach is working that you have passed values which will intantiate arraylist with the list elements.

More over

ArrayList that is returned from Arrays.asList is not an actual arraylist, it is just a wrapper which doesnt allows any modification in the list. If you try to add or remove over Arrays.asList it will give you

UnsupportedOperationException

What about a simple while loop?

while times > 0:
    do_something()
    times -= 1

You already have the variable; why not use it?

An easy way to do this is to user "select" and realize you can get a list of all columns for the dataframe, df, with df.columns

drop_list = ['a column', 'another column', ...]

df.select([column for column in df.columns if column not in drop_list])

No, because the commit message is related with the commit SHA / hash, and if we change it the commit SHA is also changed. The way I used is to create a comment on that commit. I can't think the other way.

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get<ResponseOrders >(this.baseUrl,{
       params
    }).pipe(
       map(res => res.results || []),
       catchError(error => _throwError(error.message || error))
    );
} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

Here is how I would do it in Java:

int seconds = (int) (milliseconds / 1000) % 60 ;
int minutes = (int) ((milliseconds / (1000*60)) % 60);
int hours   = (int) ((milliseconds / (1000*60*60)) % 24);

To find the fastest way to read a file line by line you will have to do some benchmarking. I have done some small tests on my computer but you cannot expect that my results apply to your environment.

Using StreamReader.ReadLine

This is basically your method. For some reason you set the buffer size to the smallest possible value (128). Increasing this will in general increase performance. The default size is 1,024 and other good choices are 512 (the sector size in Windows) or 4,096 (the cluster size in NTFS). You will have to run a benchmark to determine an optimal buffer size. A bigger buffer is - if not faster - at least not slower than a smaller buffer.

const Int32 BufferSize = 128;
using (var fileStream = File.OpenRead(fileName))
  using (var streamReader = new StreamReader(fileStream, Encoding.UTF8, true, BufferSize)) {
    String line;
    while ((line = streamReader.ReadLine()) != null)
      // Process line
  }

The FileStream constructor allows you to specify FileOptions. For example, if you are reading a large file sequentially from beginning to end, you may benefit from FileOptions.SequentialScan. Again, benchmarking is the best thing you can do.

Using File.ReadLines

This is very much like your own solution except that it is implemented using a StreamReader with a fixed buffer size of 1,024. On my computer this results in slightly better performance compared to your code with the buffer size of 128. However, you can get the same performance increase by using a larger buffer size. This method is implemented using an iterator block and does not consume memory for all lines.

var lines = File.ReadLines(fileName);
foreach (var line in lines)
  // Process line

Using File.ReadAllLines

This is very much like the previous method except that this method grows a list of strings used to create the returned array of lines so the memory requirements are higher. However, it returns String[] and not an IEnumerable<String> allowing you to randomly access the lines.

var lines = File.ReadAllLines(fileName);
for (var i = 0; i < lines.Length; i += 1) {
  var line = lines[i];
  // Process line
}

Using String.Split

This method is considerably slower, at least on big files (tested on a 511 KB file), probably due to how String.Split is implemented. It also allocates an array for all the lines increasing the memory required compared to your solution.

using (var streamReader = File.OpenText(fileName)) {
  var lines = streamReader.ReadToEnd().Split("\r\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
  foreach (var line in lines)
    // Process line
}

My suggestion is to use File.ReadLines because it is clean and efficient. If you require special sharing options (for example you use FileShare.ReadWrite), you can use your own code but you should increase the buffer size.

There is one more ability to achieve a desired results: command trap. It can be used to clean-up purposes for example.

Well, it's fairly simple to do.

On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.

Here's the code:

private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            myCanvas.Width = e.NewSize.Width;
            myCanvas.Height = e.NewSize.Height;

            double xChange = 1, yChange = 1;

            if (e.PreviousSize.Width != 0)
            xChange = (e.NewSize.Width/e.PreviousSize.Width);

            if (e.PreviousSize.Height != 0)
            yChange = (e.NewSize.Height / e.PreviousSize.Height);

            foreach (FrameworkElement fe in myCanvas.Children )
            {   
                /*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */            
                if (fe is Grid == false)
                {
                    fe.Height = fe.ActualHeight * yChange;
                    fe.Width = fe.ActualWidth * xChange;

                    Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
                    Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);

                }
            }
        }

The Path.GetFileNameWithoutExtension method gives you the filename you pass as an argument without the extension, as should be obvious from the name.

My original suggestion was

s12 := fmt.Sprint(s1,s2)

But above answer using bytes.Buffer - WriteString() is the most efficient way.

My initial suggestion uses reflection and a type switch. See (p *pp) doPrint and (p *pp) printArg
There is no universal Stringer() interface for basic types, as I had naively thought.

At least though, Sprint() internally uses a bytes.Buffer. Thus

`s12 := fmt.Sprint(s1,s2,s3,s4,...,s1000)`

is acceptable in terms of memory allocations.

=> Sprint() concatenation can be used for quick debug output.
=> Otherwise use bytes.Buffer ... WriteString

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

For those who are looking for a tiny and smart solution:

String.prototype.toDate = function(format)
{
  var normalized      = this.replace(/[^a-zA-Z0-9]/g, '-');
  var normalizedFormat= format.toLowerCase().replace(/[^a-zA-Z0-9]/g, '-');
  var formatItems     = normalizedFormat.split('-');
  var dateItems       = normalized.split('-');

  var monthIndex  = formatItems.indexOf("mm");
  var dayIndex    = formatItems.indexOf("dd");
  var yearIndex   = formatItems.indexOf("yyyy");
  var hourIndex     = formatItems.indexOf("hh");
  var minutesIndex  = formatItems.indexOf("ii");
  var secondsIndex  = formatItems.indexOf("ss");

  var today = new Date();

  var year  = yearIndex>-1  ? dateItems[yearIndex]    : today.getFullYear();
  var month = monthIndex>-1 ? dateItems[monthIndex]-1 : today.getMonth()-1;
  var day   = dayIndex>-1   ? dateItems[dayIndex]     : today.getDate();

  var hour    = hourIndex>-1      ? dateItems[hourIndex]    : today.getHours();
  var minute  = minutesIndex>-1   ? dateItems[minutesIndex] : today.getMinutes();
  var second  = secondsIndex>-1   ? dateItems[secondsIndex] : today.getSeconds();

  return new Date(year,month,day,hour,minute,second);
};

Example:

"22/03/2016 14:03:01".toDate("dd/mm/yyyy hh:ii:ss");
"2016-03-29 18:30:00".toDate("yyyy-mm-dd hh:ii:ss");

Note that apart from rows and columns there is a number of channels and type. When it is clear what type is, the channels can act as an extra dimension as in CV_8UC3 so you would address a matrix as

uchar a = M.at<Vec3b>(y, x)[i];

So the size in terms of elements of elementary type is M.rows * M.cols * M.cn

To find the max element one can use

Mat src;
double minVal, maxVal;
minMaxLoc(src, &minVal, &maxVal);

I see this is a fairly old question, but this looks like one of those times when something's been written without knowledge of a language feature. The collections library exists to fulfill these purposes.

from collections import Counter
letter_counter = Counter()
for letter in 'The quick brown fox jumps over the lazy dog':
    letter_counter[letter] += 1

>>> letter_counter
Counter({' ': 8, 'o': 4, 'e': 3, 'h': 2, 'r': 2, 'u': 2, 'T': 1, 'a': 1, 'c': 1, 'b': 1, 'd': 1, 'g': 1, 'f': 1, 'i': 1, 'k': 1, 'j': 1, 'm': 1, 'l': 1, 'n': 1, 'q': 1, 'p': 1, 's': 1, 't': 1, 'w': 1, 'v': 1, 'y': 1, 'x': 1, 'z': 1})

In this example the spaces are being counted, obviously, but whether or not you want those filtered is up to you.

As for the dict.get(a_key, default_value), there have been several answers to this particular question -- this method returns the value of the key, or the default_value you supply. The first argument is the key you're looking for, the second argument is the default for when that key is not present.

Building on top of Mike Causer's answer I've made this function which takes into consideration multiple params with the same key (foo=bar&foo=baz) and also comma-separated parameters (foo=bar,baz,bin). It also lets you search for a certain query key.

function getQueryParams(queryKey) {
    var queryString = window.location.search;
    var query = {};
    var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
    for (var i = 0; i < pairs.length; i++) {
        var pair = pairs[i].split('=');
        var key = decodeURIComponent(pair[0]);
        var value = decodeURIComponent(pair[1] || '');
        // Se possui uma vírgula no valor, converter em um array
        value = (value.indexOf(',') === -1 ? value : value.split(','));

        // Se a key já existe, tratar ela como um array
        if (query[key]) {
            if (query[key].constructor === Array) {
                // Array.concat() faz merge se o valor inserido for um array
                query[key] = query[key].concat(value);
            } else {
                // Se não for um array, criar um array contendo o valor anterior e o novo valor
                query[key] = [query[key], value];
            }
        } else {
            query[key] = value;
        }
    }

    if (typeof queryKey === 'undefined') {
        return query;
    } else {
        return query[queryKey];
    }
}

Example input: foo.html?foo=bar&foo=baz&foo=bez,boz,buz&bar=1,2,3

Example output

{
    foo: ["bar","baz","bez","boz","buz"],
    bar: ["1","2","3"]
}

There's a great article on Mozilla's MDN docs that describes exactly this issue:

The "Unicode Problem" Since DOMStrings are 16-bit-encoded strings, in most browsers calling window.btoa on a Unicode string will cause a Character Out Of Range exception if a character exceeds the range of a 8-bit byte (0x00~0xFF). There are two possible methods to solve this problem:

• the first one is to escape the whole string (with UTF-8, see encodeURIComponent) and then encode it;
• the second one is to convert the UTF-16 DOMString to an UTF-8 array of characters and then encode it.

A note on previous solutions: the MDN article originally suggested using unescape and escape to solve the Character Out Of Range exception problem, but they have since been deprecated. Some other answers here have suggested working around this with decodeURIComponent and encodeURIComponent, this has proven to be unreliable and unpredictable. The most recent update to this answer uses modern JavaScript functions to improve speed and modernize code.

If you're trying to save yourself some time, you could also consider using a library:

• js-base64 (NPM, great for Node.js)
• base64-js

Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    // first we use encodeURIComponent to get percent-encoded UTF-8,
    // then we convert the percent encodings into raw bytes which
    // can be fed into btoa.
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g,
        function toSolidBytes(match, p1) {
            return String.fromCharCode('0x' + p1);
    }));
}

b64EncodeUnicode('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n'); // "Cg=="

Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    // Going backwards: from bytestream, to percent-encoding, to original string.
    return decodeURIComponent(atob(str).split('').map(function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
    }).join(''));
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
b64DecodeUnicode('Cg=='); // "\n"

The pre-2018 solution (functional, and though likely better support for older browsers, not up to date)

Here is the the current recommendation, direct from MDN, with some additional TypeScript compatibility via @MA-Maddin:

// Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g, function(match, p1) {
        return String.fromCharCode(parseInt(p1, 16))
    }))
}

b64EncodeUnicode('? à la mode') // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n') // "Cg=="

// Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    return decodeURIComponent(Array.prototype.map.call(atob(str), function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2)
    }).join(''))
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU=') // "? à la mode"
b64DecodeUnicode('Cg==') // "\n"

The original solution (deprecated)

This used escape and unescape (which are now deprecated, though this still works in all modern browsers):

function utf8_to_b64( str ) {
    return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
    return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

And one last thing: I first encountered this problem when calling the GitHub API. To get this to work on (Mobile) Safari properly, I actually had to strip all white space from the base64 source before I could even decode the source. Whether or not this is still relevant in 2017, I don't know:

function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(escape(window.atob( str )));
}

This works with Bootstrap 3 FYI

$('#myModal').on('hidden.bs.modal', function () {
  $(this).removeData('bs.modal');
});

XML Element is a XML Node but with additional elements like attributes.

<a>Lorem Ipsum</a>  //This is a node

<a id="sample">Lorem Ipsum</a>  //This is an element

Try this -

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

Alternatively,

1. you could also declare in your manifest file's activity -

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main"
          android:label="@string/app_name"
          android:windowSoftInputMode="stateHidden"
          >

2. If you have already been using android:windowSoftInputMode for a value like adjustResize or adjustPan, you can combine two values like:

<activity
        ...
        android:windowSoftInputMode="stateHidden|adjustPan"
        ...
        >

This will hide the keyboard whenever appropriate but pan the activity view in case the keyboard has to be shown.

If you don't know that you will get an array of dictionaries or single dictionary in the response from server you need to check whether the result contains an array or not.
In my case always receiving an array of dictionaries except once. So, to handle that I used the below code for swift 3.

if let str = strDict["item"] as? Array<Any>

Here as? Array checks whether the obtained value is array (of dictionary items). In else case you can handle if it is single dictionary item which is not kept inside an array.

Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.

In your case:

w_ (array, std::end(array))

• array will get us a pointer to the beginning of the array (didn't catch it's name),
• std::end(array) will get us an iterator to the end of the array.

ssh-keygen -R hostname

This deletes the offending key from the known_hosts

The man page entry reads:

-R hostname Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).

Use .length to count number of characters, and $.trim() function to remove spaces, and replace(/ /g,'') to replace multiple spaces with just one. Here is an example:

   var str = "      Hel  lo       ";
   console.log(str.length); 
   console.log($.trim(str).length); 
   console.log(str.replace(/ /g,'').length); 

Output:

20
7
5

Source: How to count number of characters in a string with JQuery

A possibly simpler alternative to editing the ssh config file (as suggested in all other answers), is to configure an individual repository to use a different (e.g. non-default) ssh key.

Inside the repository for which you want to use a different key, run:

git config core.sshCommand 'ssh -i ~/.ssh/id_rsa_anotheraccount'

If your key is passhprase-protected and you don't want to type your password every time, you have to add it to the ssh-agent. Here's how to do it for ubuntu and here for macOS.

^{It should also be possible to scale this approach to multiple repositories using global git config and conditional includes (see example).}

in my case,

dev@Dev-007:~$ mysql -u root -p
Enter password: 
ERROR 1698 (28000): Access denied for user 'root'@'localhost'

I am sure my password was correct otherwise error code would be ERROR 1045 (28000): Access denied for user

so i relogin using sudo,

dev@Dev-007:~$ sudo mysql -u root -p

this time it worked for me . see the docs

and then change root password,

mysql> alter user 'root'@'%' identified with mysql_native_password by 'me123';
Query OK, 0 rows affected (0.14 sec)

mysql> 

then restart server using sudo /etc/init.d/mysql restart

Just a silly mistake use quote('') in '200px'

 <html>
  <head>    
  </head>

<body >
    <button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px';">Click Me!</button>
    <div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>

Without using "var" variables can only define when set a value. In example:

my_var;

cannot work in global scope or any other scope. It should be with value like:

my_var = "value";

On the other hand you can define a vaiable like;

var my_var;

Its value is undefined ( Its value is not null and it is not equal to null interestingly.).

As the jQuery API says: "Load JSON-encoded data from the server using a GET HTTP request."

So you cannot load a local file with that function. But as you browse the web then you will see that loading a file from filesystem is really difficult in javascript as the following thread says:

Local file access with javascript

Changing only what's after hash - old browsers

document.location.hash = 'lookAtMeNow';

Changing full URL. Chrome, Firefox, IE10+

history.pushState('data to be passed', 'Title of the page', '/test');

The above will add a new entry to the history so you can press Back button to go to the previous state. To change the URL in place without adding a new entry to history use

history.replaceState('data to be passed', 'Title of the page', '/test');

Try running these in the console now!

AX is the 16 lower bits of EAX. AH is the 8 high bits of AX (i.e. the bits 8-15 of EAX) and AL is the least significant byte (bits 0-7) of EAX as well as AX.

Example (Hexadecimal digits):

EAX: 12 34 56 78
AX: 56 78
AH: 56
AL: 78

You can make a list copy of the dict.Values, then you can use the List.ForEach lambda function for iteration, (or a foreach loop, as suggested before).

new List<string>(myDict.Values).ForEach(str =>
{
  //Use str in any other way you need here.
  Console.WriteLine(str);
});

If you want to remove \n from the last element only, use this:

t[-1] = t[-1].strip()

If you want to remove \n from all the elements, use this:

t = map(lambda s: s.strip(), t)

You might also consider removing \n before splitting the line:

line = line.strip()
# split line...

You have to use Appcompat library for that. Which is used like below:

dashboard.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:tools="http://schemas.android.com/tools"
      xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_search"
        android:icon="@android:drawable/ic_menu_search"
        app:showAsAction="always|collapseActionView"
        app:actionViewClass="androidx.appcompat.widget.SearchView"
        android:title="Search"/>
</menu>

Activity file (in Java):

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.dashboard, menu);

     MenuItem searchItem = menu.findItem(R.id.action_search);

    SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = null;
    if (searchItem != null) {
        searchView = (SearchView) searchItem.getActionView();
    }
    if (searchView != null) {
        searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName()));
    }
        return super.onCreateOptionsMenu(menu);
}

Activity file (in Kotlin):

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    menuInflater.inflate(R.menu.menu_search, menu)

    val searchItem: MenuItem? = menu?.findItem(R.id.action_search)
    val searchManager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
    val searchView: SearchView? = searchItem?.actionView as SearchView

    searchView?.setSearchableInfo(searchManager.getSearchableInfo(componentName))
    return super.onCreateOptionsMenu(menu)
}

manifest file:

<meta-data 
      android:name="android.app.default_searchable" 
      android:value="com.apkgetter.SearchResultsActivity" /> 

        <activity
            android:name="com.apkgetter.SearchResultsActivity"
            android:label="@string/app_name"
            android:launchMode="singleTop" >
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
            </intent-filter>

            <meta-data
                android:name="android.app.searchable"
                android:resource="@xml/searchable" />
        </activity>

searchable xml file:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:hint="@string/search_hint"
    android:label="@string/app_name" />

And at last, your SearchResultsActivity class code. for showing result of your search.

you didn't give a value for id. Try this :

INSERT INTO role (id, name, created) VALUES ('example1','Content Coordinator', GETDATE()), ('example2', 'Content Viewer', GETDATE())

Or you can set the auto increment on id field, if you need the id value added automatically.

right click on the pivot table in excel choose wizard click 'back' click 'get data...' in the query window File - Table Definition

then you can create a new or choose a different connection

worked perfectly.

the get data button is next to the tiny button with a red arrow next to the range text input box.

In some cases, when necessary using has been obviously added and studio can't see this namespace, studio restart can save the day.

Some of the other answers are great for removing zeros from existing data, but if you have a working sheet that is constantly changed and want to prevent zeros from ever appearing, I find it's easiest to use conditional formatting to make them invisible. Just select the range of cells you want to apply it to > conditional formatting > new rule.

Change the rule type to "format only cells that contain" Cell value > equal to > 0.

Under "Format" change the text colour to white or whatever your background happens to be, and all cells which contain exactly zero will disappear.

Obviously this also works with any other value you want to make disappear.

Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:

#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"

The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).

If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.

If you want to roll your own, for just the one specific case, you could do something like this:

if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
    ext_program="${1:7}"
else
    ext_program="default program"
fi

As an addendum to akf's answer you could use instanceof checks instead of String equals() calls:

String cname="com.some.vendor.Impl";
try {
  Class c=this.getClass().getClassLoader().loadClass(cname);
  Object o= c.newInstance();
  if(o instanceof Spam) {
    Spam spam=(Spam) o;
    process(spam);
  }
  else if(o instanceof Ham) {
    Ham ham = (Ham) o;
    process(ham);
  }
  /* etcetera */
}
catch(SecurityException se) {
  System.err.printf("Someone trying to game the system?%nOr a rename is in order because this JVM doesn't feel comfortable with: “%s”", cname);
  se.printStackTrace();
}
catch(LinkageError le) {
  System.err.printf("Seems like a bad class to this JVM: “%s”.", cname);
  le.printStackTrace();
}
catch(RuntimeException re) { 
  // runtime exceptions I might have forgotten. Classloaders are wont to produce those.
  re.printStackTrace();
}
catch(Exception e) { 
  e.printStackTrace();
}

Note the liberal hardcoding of some values. Anyways the main points are:

1. Use instanceof rather than equals(). If anything, it will co-operate better when refactoring.
2. Be sure to catch these runtime errors and security ones too.

Export like export default HelloWorld; and import, such as import React from 'react' are part of the ES6 modules system.

A module is a self contained unit that can expose assets to other modules using export, and acquire assets from other modules using import.

In your code:

import React from 'react'; // get the React object from the react module

class HelloWorld extends React.Component {
  render() {
    return <p>Hello, world!</p>;
  }
}

export default HelloWorld; // expose the HelloWorld component to other modules

In ES6 there are two kinds of exports:

Named exports - for example export function func() {} is a named export with the name of func. Named modules can be imported using import { exportName } from 'module';. In this case, the name of the import should be the same as the name of the export. To import the func in the example, you'll have to use import { func } from 'module';. There can be multiple named exports in one module.

Default export - is the value that will be imported from the module, if you use the simple import statement import X from 'module'. X is the name that will be given locally to the variable assigned to contain the value, and it doesn't have to be named like the origin export. There can be only one default export.

A module can contain both named exports and a default export, and they can be imported together using import defaultExport, { namedExport1, namedExport3, etc... } from 'module';.

In my case, I am working on angularv10 with material. I had changed some script files and forgot to remove these empty "" in the scripts array

scripts: [.....bla, bla, etc, ""]

remove these empty""

npm clear-cache --force

close and open vscode

It worked.

For SAPI: php-fpm

There is no need to create a php.info file (it is not a good policy to leave it for the world to read anyway). On the command line:

php-fpm -i | more

Somewhere in its output, it will show this line:

Configuration File (php.ini) Path => /etc

Here is a more complete explanation: https://www.cloudinsidr.com/content/how-to-figure-out-your-php-configuration-parameters-without-info-php/

I got similar error while using in-app-purchase in android. My mistake is I used wrong purchase id while instantiating the purchases.

public static final String PRODUCT_ID_ASTRO_Match = "android.test.product";//wrong id not in play store dev console

Replaced it with:

public static final String PRODUCT_ID_ASTRO_Match = "android.test.purchased";

and it worked.

The cut command is designed for this exact situation. It will "cut" on any delimiter and then you can specify which chunks should be output.

For instance: echo "foo bar <foo> bla 1 2 3.4" | cut -d " " -f 6-7

Will result in output of: 2 3.4

-d sets the delimiter

-f selects the range of 'fields' to output, in this case, it's the 6th through 7th chunks of the original string. You can also specify the range as a list, such as 6,7.

You will need a PDF renderer. There are a few more or less good ones on the market (ICEPdf, pdfrenderer), but without, you will have to rely on external tools. The free PDF renderers also cannot render embedded fonts, and so will only be good for creating thumbnails (what you eventually want).

My favorite external tool is Ghostscript, which can convert PDFs to images with a single command line invocation.

This converts Postscript (and PDF?) files to bmp for us, just as a guide to modify for your needs (Know you need the env vars for gs to work!):

pushd 
setlocal

Set BIN_DIR=C:\Program Files\IKOffice_ACME\bin
Set GS=C:\Program Files\IKOffice_ACME\gs
Set GS_DLL=%GS%\gs8.54\bin\gsdll32.dll
Set GS_LIB=%GS%\gs8.54\lib;%GS%\gs8.54\Resource;%GS%\fonts
Set Path=%Path%;%GS%\gs8.54\bin
Set Path=%Path%;%GS%\gs8.54\lib

call "%GS%\gs8.54\bin\gswin32c.exe" -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE#bmpmono -r600x600 -sOutputFile#%2 -f %1

endlocal
popd

UPDATE: pdfbox is now able to embed fonts, so no need for Ghostscript anymore.

You can set custom color using this-

check out this - click hear

XSSFWorkbook workbook = new XSSFWorkbook();

IndexedColorMap colorMap = workbook.getStylesSource().getIndexedColors();
Font tableHeadOneFontStyle = workbook.createFont();
        tableHeadOneFontStyle.setBold( true );
        tableHeadOneFontStyle.setColor( IndexedColors.BLACK.getIndex() );

XSSFCellStyle tableHeaderOneColOneStyle = workbook.createCellStyle();
        tableHeaderOneColOneStyle.setFont( tableHeadOneFontStyle );
        tableHeaderOneColOneStyle
                .setFillForegroundColor( new XSSFColor( new java.awt.Color( 255, 231, 153 ), colorMap ) );
        tableHeaderOneColOneStyle.setFillPattern( FillPatternType.SOLID_FOREGROUND );
        tableHeaderOneColOneStyle = setLeftRightBorderColor( tableHeaderOneColOneStyle );
        tableHeaderOneColOneStyle = alignCenter( tableHeaderOneColOneStyle );

printing a list can also cause this problem (im new in python, so it confused me a bit too):

>>>myList = ['\\']
>>>print myList
['\\']
>>>print ''.join(myList)
\ 

similarly:

>>>myList = ['\&']
>>>print myList
['\\&']
>>>print ''.join(myList)

Max is on he right track with the suggestion to use Windows Scripting for a way to do it without installing any additional executables on the machine. His code will work if you have the IIS SMTP service setup to forward outbound email using the "smart host" setting, or the machine also happens to be running Microsoft Exchange. Otherwise if this is not configured, you will find your emails just piling up in the message queue folder (\inetpub\mailroot\queue). So, unless you can configure this service, you also want to be able to specify the email server you want to use to send the message with. To do that, you can do something like this in your windows script file:

Set objMail = CreateObject("CDO.Message")
Set objConf = CreateObject("CDO.Configuration")
Set objFlds = objConf.Fields
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 'cdoSendUsingPort
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.your-site-url.com" 'your smtp server domain or IP address goes here
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 'default port for email
'uncomment next three lines if you need to use SMTP Authorization
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "your-username"
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "your-password"
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1 'cdoBasic
objFlds.Update
objMail.Configuration = objConf
objMail.FromName = "Your Name"
objMail.From = "[email protected]"
objMail.To = "[email protected]"
objMail.Subject = "Email Subject Text"
objMail.TextBody = "The message of the email..."
objMail.Send
Set objFlds = Nothing
Set objConf = Nothing
Set objMail = Nothing

This is what worked for me:

  new ClassPathXmlApplicationContext("classpath:beans.xml");

yes,the sorting proceed differently. in first scenario, orders based on column1 and in addition to that process further by sorting colmun2 based on column1 .. in second scenario ,it orders completely based on column 1 only... please proceed with a simple example...u will get quickly..

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

As google says:

Paste it into your web page, just before the closing </head> tag.

One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. It is customary to place JavaScript code in the <head> section, and we recommend placing the snippet at the bottom of the <head> section for best performance

For users loading remote data, this will reset the select2 to the placeholder without firing off ajax. Works with v4.0.3:

$("#lstProducts").val("").trigger("change.select2");

Looks like it could be throwing the error on the empty data row, have you tried to just make sure itemDate isn't empty before you run the CDate() function? I think this might be your problem.

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

Since java 7 you can the java.nio package to achieve the same result:

Path dir = ...;
List<File> files = new ArrayList<>();
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir, "*.{java,class,jar}")) {
    for (Path entry: stream) {
        files.add(entry.toFile());
    }
    return files;
} catch (IOException x) {
    throw new RuntimeException(String.format("error reading folder %s: %s",
    dir,
    x.getMessage()),
    x);
}

Browse to its page in the package index, eg. http://www.nuget.org/packages/Newtonsoft.Json/4.0.5

Then follow the install instructions given:

Install-Package Newtonsoft.Json -Version 4.0.5

Alternatively to download the .nupkg file, follow the 'Download' link eg. https://www.nuget.org/api/v2/package/Newtonsoft.Json/4.0.5

Obsolete: install my Chrome extension Nutake which inserts a download link.

Note - Compare Only Date Part:

When we compare two date in javascript. It takes hours, minutes and seconds also into consideration.. So If we only need to compare date only, this is the approach:

var date1= new Date("01/01/2014").setHours(0,0,0,0);

var date2= new Date("01/01/2014").setHours(0,0,0,0);

Now: if date1.valueOf()> date2.valueOf() will work like a charm.

1) WebClient is a managed type, so you don't need a finalizer. The finalizer is needed in the case your users don't Dispose() of your NoGateway class and the native type (which is not collected by the GC) needs to be cleaned up after. In this case, if the user doesn't call Dispose(), the contained WebClient will be disposed by the GC right after the NoGateway does.

2) Indirectly yes, but you shouldn't have to worry about it. Your code is correct as stands and you cannot prevent your users from forgetting to Dispose() very easily.

I had a similar problem, using pip3 and all these things worked for installing matplotlib but not pyplot. This solved it for me:

import matplotlib as plt
from matplotlib import pyplot as pllt

Here is how to do this as of Typescript 2.0: (tsd and typings are being deprecated in favor of the following):

$ npm install --save lodash

# This is the new bit here: 
$ npm install --save-dev @types/lodash

Then, in your .ts file:

Either:

import * as _ from "lodash";

Or (as suggested by @Naitik):

import _ from "lodash";

I'm not positive what the difference is. We use and prefer the first syntax. However, some report that the first syntax doesn't work for them, and someone else has commented that the latter syntax is incompatible with lazy loaded webpack modules. YMMV.

Edit on Feb 27th, 2017:

According to @Koert below, import * as _ from "lodash"; is the only working syntax as of Typescript 2.2.1, lodash 4.17.4, and @types/lodash 4.14.53. He says that the other suggested import syntax gives the error "has no default export".

You could replace all spaces by an empty string, all comas by dots and then parse it.

var str = "110 000,23";
var num = parseFloat(str.replace(/\s/g, "").replace(",", "."));
console.log(num);

I used a regex in the first one to be able to match all spaces, not just the first one.

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

Try

h4{ display:block;}

in your css

http://jsfiddle.net/ZrJP6/

You can only delete with your time field, which is a number.

Delete from <measurement> where time=123456

will work. Remember not to give single quotes or double quotes. Its a number.

Your HTTP client disconnected.

This could have a couple of reasons:

• Responding to the request took too long, the client gave up
• You responded with something the client did not understand
• The end-user actually cancelled the request
• A network error occurred
• ... probably more

You can fairly easily emulate the behavior:

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);

<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

In above html tag we have different attributes like src, alt, width and height.

If you want to get the any attribute value from above html tag you have to pass attribute value in getAttribute() method

Syntax:

getAttribute(attributeValue)
getAttribute(src) you get w3schools.jpg
getAttribute(height) you get 142
getAttribute(width) you get 104 

if your "versionCode" in build.gradle file is less than the eralier version code then, your app wont install. Try to install with same "version code" or more than that.

I had this problem for a different reason. I went to the maven repository https://mvnrepository.com looking for the latest version of spring core, which at the time was 5.0.0.M3/ The repository showed me this entry for my pom.xml:

<!-- https://mvnrepository.com/artifact/org.springframework/spring-core -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>5.0.0.M3</version>
</dependency>

Naive fool that I am, I assumed that the comment was telling me that the jar is located in the default repository.

However, after a lot of head-banging, I saw a note just below the xml saying "Note: this artifact it located at Alfresco Public repository (https://artifacts.alfresco.com/nexus/content/repositories/public/)"

So the comment in the XML is completely misleading. The jar is located in another archive, which was why Maven couldn't find it!

To convert UTC to local time

let UTC = moment.utc()
let local = moment(UTC).local()

Or you want directly get the local time

let local = moment()

var UTC = moment.utc()_x000D_
console.log(UTC.format()); // UTC time_x000D_
_x000D_
var cLocal = UTC.local()_x000D_
console.log(cLocal.format()); // Convert UTC time_x000D_
_x000D_
var local = moment();_x000D_
console.log(local.format()); // Local time

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>

I think the best solution is suggested by @T. Stone, but I don't know why just don't use the DEBUG flag in Django. I Write the below code for my website:

if DEBUG:
    from .local_settings import *

Always the simple solutions are better than complex ones.

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

I'm afraid it can't be done, the pseudo-class selectors can't be set in-line, you'll have to do it on the page or on a stylesheet.

I should mention that technically you should be able to do it according to the CSS spec, but most browsers don't support it

Edit: I just did a quick test with this:

<a href="test.html" style="{color: blue; background: white} 
            :visited {color: green}
            :hover {background: yellow}
            :visited:hover {color: purple}">Test</a>

And it doesn't work in IE7, IE8 beta 2, Firefox or Chrome. Can anyone else test in any other browsers?

If It is simple Session you can apply NULL Check directly Session["emp_num"] != null

But if it's a session of a list Item then You need to apply any one of the following option

Option 1:

if (((List<int>)(Session["emp_num"])) != null && (List<int>)Session["emp_num"])).Count > 0)
 {
 //Your Logic here
 }

Option 2:

List<int> val= Session["emp_num"] as List<int>;  //Get the value from Session.

if (val.FirstOrDefault() != null)
 {
 //Your Logic here
 }

I Just put my view background (color code) as ClipArt og Image background, and it looks like transparent or no background where both have the same color as background.

The short answer is that history.pushState (not History.pushState, which would throw an exception, the window part is optional) will never do what you suggest.

If pages are refreshing, then it is caused by other things that you are doing (for example, you might have code running that goes to a new location in the case of the address bar changing).

history.pushState({urlPath:'/page2.php'},"",'/page2.php') works exactly like it is supposed to in the latest versions of Chrome, IE and Firefox for me and my colleagues.

In fact you can put whatever you like into the function: history.pushState({}, '', 'So long and thanks for all the fish.not a real file').

If you post some more code (with special attention for code nearby the history.pushState and anywhere document.location is used), then we'll be more than happy to help you figure out where exactly this issue is coming from.

If you post more code, I'll update this answer (I have your question favourited) :).

Here is a simple mathed to pass values from a route provider

//Route Provider
$routeProvider.when("/page/:val1/:val2/:val3",{controller:pageCTRL, templateUrl: 'pages.html'});


//Controller
$http.get( 'page.php?val1='+$routeParams.val1 +'&val2='+$routeParams.val2 +'&val3='+$routeParams.val3 , { cache: true})
        .then(function(res){
            //....
        })

Use the setAttribute method:

document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");

But you really should be using data followed with a dash and with its property, like:

<li ... data-icon="base.gif" ...>

And to do it in JS use the dataset property:

document.getElementById('item1').dataset.icon = "base.gif";

The other answer (to date) appear to check for substrings rather than words. Major difference.

With the help of this article, I have created this simple method:

static boolean containsWord(String mainString, String word) {

    Pattern pattern = Pattern.compile("\\b" + word + "\\b", Pattern.CASE_INSENSITIVE); // "\\b" represents any word boundary.
    Matcher matcher = pattern.matcher(mainString);
    return matcher.find();
}

Of course! jQuery is just a library that utilizes javascript after all.

You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.

elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';

Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.

As noted above the problem is in specifying the path to your file. The default path in OS X is your home directory (/Users/macbook represented by ~ in terminal ...you can change or rename the home directory with the advanced options in System Preferences > Users & Groups).

Or you can specify the path from the drive to your file in the filename:

path = "/Users/macbook/Documents/MyPython/"
myFile = path + fileName

You can also catch the File Not Found Error and give another response using try:

try:
    with open(filename) as f:
        sequences = pick_lines(f)
except FileNotFoundError:
    print("File not found. Check the path variable and filename")
    exit()

ArrayList and Vector both implements List interface and maintains insertion order.But there are many differences between ArrayList and Vector classes...

ArrayList -

1. ArrayList is not synchronized.
2. ArrayList increments 50% of current array size if number of element exceeds from its capacity.
3. ArrayList is not a legacy class, it is introduced in JDK 1.2.
4. ArrayList is fast because it is non-synchronized.
5. ArrayList uses Iterator interface to traverse the elements.

Vector -

6. Vector is synchronized.
7. Vector increments 100% means doubles the array size if total number of element exceeds than its capacity.

8. Vector is a legacy class.

9. Vector is slow because it is synchronized i.e. in multithreading environment, it will hold the other threads in runnable or non-runnable state until current thread releases the lock of object.

10. Vector uses Enumeration interface to traverse the elements. But it can use Iterator also.

2. i went to MySQL > Service administration 'wampmysqld64' > install service
3. Then click on wamp icon > Restart all service.

talonmies' answer above is a fine way to abort an application in an assert-style manner.

Occasionally we may wish to report and recover from an error condition in a C++ context as part of a larger application.

Here's a reasonably terse way to do that by throwing a C++ exception derived from std::runtime_error using thrust::system_error:

#include <thrust/system_error.h>
#include <thrust/system/cuda/error.h>
#include <sstream>

void throw_on_cuda_error(cudaError_t code, const char *file, int line)
{
  if(code != cudaSuccess)
  {
    std::stringstream ss;
    ss << file << "(" << line << ")";
    std::string file_and_line;
    ss >> file_and_line;
    throw thrust::system_error(code, thrust::cuda_category(), file_and_line);
  }
}

This will incorporate the filename, line number, and an English language description of the cudaError_t into the thrown exception's .what() member:

#include <iostream>

int main()
{
  try
  {
    // do something crazy
    throw_on_cuda_error(cudaSetDevice(-1), __FILE__, __LINE__);
  }
  catch(thrust::system_error &e)
  {
    std::cerr << "CUDA error after cudaSetDevice: " << e.what() << std::endl;

    // oops, recover
    cudaSetDevice(0);
  }

  return 0;
}

The output:

$ nvcc exception.cu -run
CUDA error after cudaSetDevice: exception.cu(23): invalid device ordinal

A client of some_function can distinguish CUDA errors from other kinds of errors if desired:

try
{
  // call some_function which may throw something
  some_function();
}
catch(thrust::system_error &e)
{
  std::cerr << "CUDA error during some_function: " << e.what() << std::endl;
}
catch(std::bad_alloc &e)
{
  std::cerr << "Bad memory allocation during some_function: " << e.what() << std::endl;
}
catch(std::runtime_error &e)
{
  std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}
catch(...)
{
  std::cerr << "Some other kind of error during some_function" << std::endl;

  // no idea what to do, so just rethrow the exception
  throw;
}

Because thrust::system_error is a std::runtime_error, we can alternatively handle it in the same manner of a broad class of errors if we don't require the precision of the previous example:

try
{
  // call some_function which may throw something
  some_function();
}
catch(std::runtime_error &e)
{
  std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}

I solved this on windows by doing this:

• Open Power shell console
• run dir
• Alt-click and drag over the file/folder name column, then copy
• Paste to notepad++
• run replace with regex: replace (.*) with git mv ".\\\1" ".\\<New_Folder_Here>\"
• copy all text from notepad++ into powershell
• hit enter

Origin is the shortname that acts like an alias for the url of the remote repository.

Let me explain with an example.

Suppose you have a remote repository called amazing-project and then you clone that remote repository to your local machine so that you have a local repository. Then you would have something like what you can see in the diagram below:

Because you cloned the repository. The remote repository and the local repository are linked.

If you run the command git remote -v it will list all the remote repositories that are linked to your local repository. There you will see that in order to push or fetch code from your remote repository you will use the shortname 'origin'.

Now, this may be a bit confusing because in GitHub (or the remote server) the project is called 'amazing-project'. So why does it seem like there are two names for the remote repository?

Well one of the names that we have for our repository is the name it has on GitHub or a remote server somewhere. This can be kind of thought like a project name. And in our case that is 'amazing-project'.

The other name that we have for our repository is the shortname that it has in our local repository that is related to the URL of the repository. It is the shortname we are going to use whenever we want to push or fetch code from that remote repository. And this shortname kind of acts like an alias for the url, it's a way for us to avoid having to use that entire long url in order to push or fetch code. And in our example above it is called origin.

So, what is origin?

Basically origin is the default shortname that Git uses for a remote repository when you clone that remote repository. So it's just the default.

In many cases you will have links to multiple remote repositories in your local repository and each of those will have a different shortname.

So final question, why don't we just use the same name?

I will answer that question with another example. Suppose we have a friend who forks our remote repository so they can help us on our project. And let's assume we want to be able to fetch code from their remote repository. We can use the command git remote add <shortname> <url> in order to add a link to their remote repository in our local repository.

In the above image you can see that I used the shortname friend to refer to my friend's remote repository. You can also see that both of the remote repositories have the same project name amazing-project and that gives us one reason why the remote repository names in the remote server and the shortnames in our local repositories should not be the same!

There is a really helpful video that explains all of this that can be found here.

Don't know what you are doing (helpful to show what you tried that didn't work), but your claim that cex.axis only affects the x-axis is not true:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data = foo, cex.axis = 3)

at least for me with:

Also, cex.axis affects the labelling of tick marks. cex.lab is used to control what R call the axis labels.

plot(Y ~ X, data = foo, cex.lab = 3)

but even that works for both the x- and y-axis.

Following up Jens' comment about using barplot(). Check out the cex.names argument to barplot(), which allows you to control the bar labels:

dat <- rpois(10, 3) names(dat) <- LETTERS[1:10] barplot(dat, cex.names = 3, cex.axis = 2)

As you mention that cex.axis was only affecting the x-axis I presume you had horiz = TRUE in your barplot() call as well? As the bar labels are not drawn with an axis() call, applying Joris' (otherwise very useful) answer with individual axis() calls won't help in this situation with you using barplot()

In my case, I'm trying to access a file that is set to be read-only

And I solved it by disabling read-only and I got it fixed!

Hope it can be helpful for someone experiencing a situation like me.

I think the best approach here is to plan your code so that $items is always an array. The easiest solution is to initialize it at the top of your code with $items=array(). This way it will represent empty array even if you don't assign any value to it.

All other solutions are quite dirty hacks to me.

Try the following steps on Windows 10:

• Search for Visual Studio on the Start window and select "Open file location":

  

• Select "Troubleshoot compatibility" :

  

• Select "troubleshoot program":

  

  • Raise permissions:

  

• Select "Yes, save these settings for this program"

• Select "Close"

Once that is done, Visual Studio should be running as administrator.

I just tried. If you execute the statement to generate your local table, the tool will accept that this column name exists. Just mark the table generation statement in your editor window and click execute.

I found that for extremely large lists of files (>1e6), these answers were too slow. Here is a solution using parallel processing in python. I know, I know, this isn't linux... but nothing else here worked.

(This saved me hours)

# delete files
import os as os
import glob
import multiprocessing as mp

directory = r'your/directory'
os.chdir(directory)


files_names = [i for i in glob.glob('*.{}'.format('pdf'))]

# report errors from pool

def callback_error(result):
    print('error', result)

# delete file using system command
def delete_files(file_name):
     os.system('rm -rf ' + file_name)

pool = mp.Pool(12)  
# or use pool = mp.Pool(mp.cpu_count())


if __name__ == '__main__':
    for file_name in files_names:
        print(file_name)
        pool.apply_async(delete_files,[file_name], error_callback=callback_error)

If error comes for ".settings/language.settings.xml" or any such file you don't need to git.

1. Team -> Commit -> Staged filelist, check if unwanted file exists, -> Right click on each-> remove from index.
2. From UnStaged filelist, check if unwanted file exists, -> Right click on each-> Ignore.

Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.

It looks like you're getting back an array. If it's always going to consist of just one element, you could do this (yes, it's pretty much the same thing as Tomalak's answer):

$.each(result[0], function(key, value){
    console.log(key, value);
});

If you might have more than one element and you'd like to iterate over them all, you could nest $.each():

$.each(result, function(key, value){
    $.each(value, function(key, value){
        console.log(key, value);
    });
});

If the column has the NOT NULL constraint then it won't be possible; but otherwise this is fine:

INSERT INTO MyTable(MyIntColumn) VALUES(NULL);

On a MacBook Pro running Mavericks, sysctl -a | grep hw.cpu will only return some cryptic details. Much more detailed and accessible information is revealed in the machdep.cpu section, ie:

sysctl -a | grep machdep.cpu

In particular, for processors with HyperThreading (HT), you'll see the total enumerated CPU count (logical_per_package) as double that of the physical core count (cores_per_package).

sysctl -a | grep machdep.cpu  | grep per_package

API Sanity Checker — test framework for C/C++ libraries:

An automatic generator of basic unit tests for a shared C/C++ library. It is able to generate reasonable (in most, but unfortunately not all, cases) input data for parameters and compose simple ("sanity" or "shallow"-quality) test cases for every function in the API through the analysis of declarations in header files.

The quality of generated tests allows to check absence of critical errors in simple use cases. The tool is able to build and execute generated tests and detect crashes (segfaults), aborts, all kinds of emitted signals, non-zero program return code and program hanging.

Unique features in comparison with CppUnit, Boost and Google Test:

• Automatic generation of test data and input arguments (even for complex data types)
• Modern and highly reusable specialized types instead of fixtures and templates
