Hi @daniel.lozynski. Access-Control-Allow-Origin is one of the worst problems web developers face when working with APIs, and I've been working on solutions for a long time.

One way to get rid of Access-Control-Allow-Origin is to use proxies. Of course, proxies sometimes have their own problems.

1. One of their problems is that it slows down your requests.
2. The next problem is that some of these proxies make a small number of requests to you during the day and sometimes leave you with an too many requests error. Of course, this problem is eliminated by switching between proxies.

However, these are all temporary problems and only occur to you during development.

Below is a list of the best proxies I have ever found.

1. https://cors-anywhere.herokuapp.com/
2. https://cors-proxy.htmldriven.com/?url=
3. https://thingproxy.freeboard.io/fetch/
4. https://thingproxy.freeboard.io
5. http://thingproxy.freeboard.io
6. http://www.whateverorigin.org/get?url=
7. http://alloworigin.com/get?url=
8. https://api.allorigins.win/get?url=
9. https://yacdn.org/proxy/

But how to use these proxies?

You can easily equip the API with a proxy and get rid of Access-Control-Allow-Origin by adding any of these addresses before your IP address.

Consider a few examples below:

• https://cors-anywhere.herokuapp.com/http://example.com/posts
• https://thingproxy.freeboard.io/fetch/http://example.com/blog/posts
• https://yacdn.org/proxy/http://example.com/blog/posts

Important:

Use of proxies is limited to online APIs. And you can not use proxies in local APIs. In the following, I will tell you to answer for local APIs as well...

So what do I think is the best solution?

I recently came across a very good Chrome extension that has not had those two proxy problems for me so far and I am very happy with it since I used it.

But the only problem with using this plugin is that you can no longer debug your project on your mobile phone with IP address. This is because this plugin only creates a proxy on your browser and no longer affects data transmission over cable by IP.

You can find and install this plugin from this link.

Allow CORS: Access-Control-Allow-Origin

You can just install this extension on your Chrome browser and have fun...!

Using this plugin is very, very simple and you just need to install it and then activate it. However, if you have a problem with it, on the page of this plugin in 'Chrome Extensions', there is a YouTube video that will completely solve your problems by watching it.

Because my favorite browser is to develop Chrome, I did not look for solutions for other extensions. So if you use Chrome, this plugin will be very useful for you as well.

Here's what I get.

I'm using Visual Studio Code and its Terminal to execute the 'npm' commands.

Visual Studio Code (not as administrator)
PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator)
Run this command after I've run something like 'ng serve'

PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator - closing and opening the IDE)
If I have already executed other commands that would impact node modules I decided to try closing Visual Studio Code first, opening it up as Administrator then running the command:

PS g:\labs\myproject> npm install bootstrap@3

Result I get then is: + [email protected]
added 115 packages and updated 1 package in 24.685s

This is not a permanent solution since I don't want to continue closing down VS Code every time I want to execute an npm command, but it did resolve the issue to a point.

Yes,

Commons library provides a built-in FixedSizeList which does not support the add, remove and clear methods (but the set method is allowed because it does not modify the List's size). In other words, if you try to call one of these methods, your list still retain the same size.

To create your fixed size list, just call

List<YourType> fixed = FixedSizeList.decorate(Arrays.asList(new YourType[100]));

You can use unmodifiableList if you want an unmodifiable view of the specified list, or read-only access to internal lists.

List<YourType> unmodifiable = java.util.Collections.unmodifiableList(internalList);

select from_unixtime(unix_timestamp(current_date, 'yyyyMMdd'),'yyyy-MM-dd');

current_date - current date

yyyyMMdd - my systems current date format;

yyyy-MM-dd - if you wish to change the format to a diff one.

Double is a wrapper class,

The Double class wraps a value of the primitive type double in an object. An object of type Double contains a single field whose type is double.

In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double.

The double data type,

The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is 4.94065645841246544e-324d to 1.79769313486231570e+308d (positive or negative). For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.

Check each datatype with their ranges : Java's Primitive Data Types.

Important Note : If you'r thinking to use double for precise values, you need to re-think before using it. Java Traps: double

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

You can drop in and out of the PHP context using the <?php and ?> tags. For example...

<?php
$array = array(1, 2, 3, 4);
?>

<table>
<thead><tr><th>Number</th></tr></thead>
<tbody>
<?php foreach ($array as $num) : ?>
<tr><td><?= htmlspecialchars($num) ?></td></tr>
<?php endforeach ?>
</tbody>
</table>

This code works well with very few requirements on external libraries and shows a basic use of int **array.

This answer shows that each array is dynamically sized, as well as how to assign a dynamically sized leaf array into the dynamically sized branch array.

This program takes arguments from STDIN in the following format:

2 2   
3 1 5 4
5 1 2 8 9 3
0 1
1 3

Code for program below...

#include <iostream>

int main()
{
    int **array_of_arrays;

    int num_arrays, num_queries;
    num_arrays = num_queries = 0;
    std::cin >> num_arrays >> num_queries;
    //std::cout << num_arrays << " " << num_queries;

    //Process the Arrays
    array_of_arrays = new int*[num_arrays];
    int size_current_array = 0;

    for (int i = 0; i < num_arrays; i++)
    {
        std::cin >> size_current_array;
        int *tmp_array = new int[size_current_array];
        for (int j = 0; j < size_current_array; j++)
        {
            int tmp = 0;
            std::cin >> tmp;
            tmp_array[j] = tmp;
        }
        array_of_arrays[i] = tmp_array;
    }


    //Process the Queries
    int x, y;
    x = y = 0;
    for (int q = 0; q < num_queries; q++)
    {
        std::cin >> x >> y;
        //std::cout << "Current x & y: " << x << ", " << y << "\n";
        std::cout << array_of_arrays[x][y] << "\n";
    }

    return 0;
}

It's a very simple implementation of int main and relies solely on std::cin and std::cout. Barebones, but good enough to show how to work with simple multidimensional arrays.

This is one alternative for achieving the same but it avoids race condition caused by having two distinct "check ..and.. create" operations.

package main

import (
    "fmt"
    "os"
)

func main()  {
    if err := ensureDir("/test-dir"); err != nil {
        fmt.Println("Directory creation failed with error: " + err.Error())
        os.Exit(1)
    }
    // Proceed forward
}

func ensureDir(dirName string) error {

    err := os.MkdirAll(dirName, os.ModeDir)

    if err == nil || os.IsExist(err) {
        return nil
    } else {
        return err
    }
}

on server console:

$ mysql -u root -p -e "SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';" 

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

I always include the js files in the head of the html document and them in the action just call the javascript function. Something like this:

action="javascript:checkout()"

You try this?

Don't forget include the script reference in the html head.

I don't know cause of that works in firefox. Regards.

You can also manually tag the column with a contrasts attribute, which seems to be respected by the regression functions:

contrasts(df$factorcol) <- contr.treatment(levels(df$factorcol),
   base=which(levels(df$factorcol) == 'RefLevel'))

Another intuitive solution could be:

class Post
{
    public $title;
    public $date;
}

$posts = array();

$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';

$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';

foreach ($posts as $post) {
  echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}

Swift Version: Swift 5.1
Mostly, you can set height in tableView delegate like this:

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
   return UIView(frame: CGRect(x: 0, y: 0, width: view.width, height: CGFloat.leastNormalMagnitude))
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
   return CGFloat.leastNormalMagnitude
}

Sometimes when you created UITableView with Xib or Storyboard, the answer of up does not work. you can try the second solution:

let headerView = UIView(frame: CGRect(x: 0, y: 0, width: 0, height: CGFloat.leastNormalMagnitude))
self.tableView.tableHeaderView = headerView

Hope it works for you!

It seems that, according to the HTML5 spec, the value property of the textarea element should return '\r\n' for a newline:

The element's value is defined to be the element's raw value with the following transformation applied:

Replace every occurrence of a "CR" (U+000D) character not followed by a "LF" (U+000A) character, and every occurrence of a "LF" (U+000A) character not preceded by a "CR" (U+000D) character, by a two-character string consisting of a U+000D CARRIAGE RETURN "CRLF" (U+000A) character pair.

Following the link to 'value' makes it clear that it refers to the value property accessed in javascript:

Form controls have a value and a checkedness. (The latter is only used by input elements.) These are used to describe how the user interacts with the control.

However, in all five major browsers (using Windows, 11/27/2015), if '\r\n' is written to a textarea, the '\r' is stripped. (To test: var e=document.createElement('textarea'); e.value='\r\n'; alert(e.value=='\n');) This is true of IE since v9. Before that, IE was returning '\r\n' and converting both '\r' and '\n' to '\r\n' (which is the HTML5 spec). So... I'm confused.

To be safe, it's usually enough to use '\r?\n' in regular expressions instead of just '\n', but if the newline sequence must be known, a test like the above can be performed in the app.

I dug deeper into this and found the best solutions are here.

http://blog.notdot.net/2010/07/Getting-unicode-right-in-Python

In my case I solved "UnicodeEncodeError: 'charmap' codec can't encode character "

original code:

print("Process lines, file_name command_line %s\n"% command_line))

New code:

print("Process lines, file_name command_line %s\n"% command_line.encode('utf-8'))  

change the opacity of the parent element with the border and this will re organize the stacked elements. This worked miraculously for me after hours of research and failed attempts. It was as simple as adding an opacity of 0.99 to re organize this paint process of browsers. Check out http://philipwalton.com/articles/what-no-one-told-you-about-z-index/

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

On my pc I need to do the following:

Scope defines the area, where functions, variables and such are available. The availability of a variable for example is defined within its the context, let's say the function, file, or object, they are defined in. We usually call these local variables.

The lexical part means that you can derive the scope from reading the source code.

Lexical scope is also known as static scope.

Dynamic scope defines global variables that can be called or referenced from anywhere after being defined. Sometimes they are called global variables, even though global variables in most programmin languages are of lexical scope. This means, it can be derived from reading the code that the variable is available in this context. Maybe one has to follow a uses or includes clause to find the instatiation or definition, but the code/compiler knows about the variable in this place.

In dynamic scoping, by contrast, you search in the local function first, then you search in the function that called the local function, then you search in the function that called that function, and so on, up the call stack. "Dynamic" refers to change, in that the call stack can be different every time a given function is called, and so the function might hit different variables depending on where it is called from. (see here)

To see an interesting example for dynamic scope see here.

For further details see here and here.

Some examples in Delphi/Object Pascal

Delphi has lexical scope.

unit Main;
uses aUnit;  // makes available all variables in interface section of aUnit

interface

  var aGlobal: string; // global in the scope of all units that use Main;
  type 
    TmyClass = class
      strict private aPrivateVar: Integer; // only known by objects of this class type
                                    // lexical: within class definition, 
                                    // reserved word private   
      public aPublicVar: double;    // known to everyboday that has access to a 
                                    // object of this class type
    end;

implementation

  var aLocalGlobal: string; // known to all functions following 
                            // the definition in this unit    

end.

The closest Delphi gets to dynamic scope is the RegisterClass()/GetClass() function pair. For its use see here.

Let's say that the time RegisterClass([TmyClass]) is called to register a certain class cannot be predicted by reading the code (it gets called in a button click method called by the user), code calling GetClass('TmyClass') will get a result or not. The call to RegisterClass() does not have to be in the lexical scope of the unit using GetClass();

Another possibility for dynamic scope are anonymous methods (closures) in Delphi 2009, as they know the variables of their calling function. It does not follow the calling path from there recursively and therefore is not fully dynamic.

All you need to do is :

arr.join('');

FIDDLE

What you are describing is actually what FontAwesome is doing already. They apply the FontAwesome font-family to the ::before pseudo element of any element that has a class that starts with "icon-".

[class^="icon-"]:before,
[class*=" icon-"]:before {
  font-family: FontAwesome;
  font-weight: normal;
  font-style: normal;
  display: inline-block;
  text-decoration: inherit;
}

Then they use the pseudo element ::before to place the icon in the element with the class. I just went to http://fortawesome.github.com/Font-Awesome/ and inspected the code to find this:

.icon-cut:before {
  content: "\f0c4";
}

So if you are looking to add the icon again, you could use the ::after element to achieve this. Or for your second part of your question, you could use the ::after pseudo element to insert the bullet character to look like a list item. Then use absolute positioning to place it to the left, or something similar.

i:after{ content: '\2022';}

Since none of the above worked for me, so I wrote my own recursive function. Call Function copyTree(dir1, dir2) to merge directories. Run on multi-platforms Linux and Windows.

def forceMergeFlatDir(srcDir, dstDir):
    if not os.path.exists(dstDir):
        os.makedirs(dstDir)
    for item in os.listdir(srcDir):
        srcFile = os.path.join(srcDir, item)
        dstFile = os.path.join(dstDir, item)
        forceCopyFile(srcFile, dstFile)

def forceCopyFile (sfile, dfile):
    if os.path.isfile(sfile):
        shutil.copy2(sfile, dfile)

def isAFlatDir(sDir):
    for item in os.listdir(sDir):
        sItem = os.path.join(sDir, item)
        if os.path.isdir(sItem):
            return False
    return True


def copyTree(src, dst):
    for item in os.listdir(src):
        s = os.path.join(src, item)
        d = os.path.join(dst, item)
        if os.path.isfile(s):
            if not os.path.exists(dst):
                os.makedirs(dst)
            forceCopyFile(s,d)
        if os.path.isdir(s):
            isRecursive = not isAFlatDir(s)
            if isRecursive:
                copyTree(s, d)
            else:
                forceMergeFlatDir(s, d)

Extending upon Mustafa's answer.

A) Install http://phantomjs.org/ and then

B) install the phantom node module https://github.com/amir20/phantomjs-node

C) Here is an example of rendering a pdf

var phantom = require('phantom');   

phantom.create().then(function(ph) {
    ph.createPage().then(function(page) {
        page.open("http://www.google.com").then(function(status) {
            page.render('google.pdf').then(function() {
                console.log('Page Rendered');
                ph.exit();
            });
        });
    });
});

Output of the PDF:

EDIT: Silent printing that PDF

java -jar pdfbox-app-2.0.2.jar PrintPDF -silentPrint C:\print_mypdf.pdf

You have to add this line just before loop

    MyFile = Dir
Loop

Best of both worlds [@DiddiZ, @Chalkos]: this one mainly builds upon @Chalkos method, but fixes a bug (ifst.next()), and improves initial checks (taken from @DiddiZ) as well as removes the need to copy the first collection (just removes items from a copy of the second collection).

Not requiring a hashing function or sorting, and enabling an early exist on un-equality, this is the most efficient implementation yet. That is unless you have a collection length in the thousands or more, and a very simple hashing function.

public static <T> boolean isCollectionMatch(Collection<T> one, Collection<T> two) {
    if (one == two)
        return true;

    // If either list is null, return whether the other is empty
    if (one == null)
        return two.isEmpty();
    if (two == null)
        return one.isEmpty();

    // If lengths are not equal, they can't possibly match
    if (one.size() != two.size())
        return false;

    // copy the second list, so it can be modified
    final List<T> ctwo = new ArrayList<>(two);

    for (T itm : one) {
        Iterator<T> it = ctwo.iterator();
        boolean gotEq = false;
        while (it.hasNext()) {
            if (itm.equals(it.next())) {
                it.remove();
                gotEq = true;
                break;
            }
        }
        if (!gotEq) return false;
    }
    // All elements in one were found in two, and they're the same size.
    return true;
}

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

The WebSocket connection starts its life with an HTTP or HTTPS handshake. When the page is accessed through HTTP, you can use WS or WSS (WebSocket secure: WS over TLS) . However, when your page is loaded through HTTPS, you can only use WSS - browsers don't allow to "downgrade" security.

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

This is a method that uses a FileUpload control in asp.net:

byte[] buffer = new byte[fu.FileContent.Length];
Stream s = fu.FileContent;
s.Read(buffer, 0, buffer.Length);
//Then save 'buffer' to the varbinary column in your db where you want to store the image.

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

Set the buttonTint property. For example, android:buttonTint="#99FF33".

My app is compiled on API LEVEL 29, but debugging on real device on API LEVEL 28.I got the warning source code does not match the bytecode in AndroidStudio.I fixed it thought these steps:

1. Go to Preferences>Instant Run: uncheck the instant run

2. Go to Build>Clean Build

3. Re-RUN the app

Now, the debug runs normal.

I find I rarely have need to use getCanonicalPath() but, if given a File with a filename that is in DOS 8.3 format on Windows, such as the java.io.tmpdir System property returns, then this method will return the "full" filename.

Form1:

    private void button1_Click(object sender, EventArgs e)
    {
        Form2 frm = new Form2(this);
        frm.Show();
    }

Form2:

public partial class Form2 : Form
{
    Form opener;

    public Form2(Form parentForm)
    {
        InitializeComponent();
        opener = parentForm;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        opener.Close();
        this.Close();
    }
}

Some Improvements in Sudheesh B Nair's answer, i have noticed it will wait for handler even while pressing back twice immediately, so cancel handler as shown below. I have cancled toast also to prevent it to display after app exit.

 boolean doubleBackToExitPressedOnce = false;
        Handler myHandler;
        Runnable myRunnable;
        Toast myToast;

    @Override
        public void onBackPressed() {
            if (doubleBackToExitPressedOnce) {
                myHandler.removeCallbacks(myRunnable);
                myToast.cancel();
                super.onBackPressed();
                return;
            }

            this.doubleBackToExitPressedOnce = true;
            myToast = Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_SHORT);
            myToast.show();

            myHandler = new Handler();

            myRunnable = new Runnable() {

                @Override
                public void run() {
                    doubleBackToExitPressedOnce = false;
                }
            };
            myHandler.postDelayed(myRunnable, 2000);
        }

On Ubuntu 18.04, I intalled gradle with:

sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle

And Ready.

I needed to know this and came here, before I remembered the Environment class.

In case anyone else had this issue, just use this: Environment.CurrentDirectory.

Example:

Dim dataDirectory As String = String.Format("{0}\Data\", Environment.CurrentDirectory)

When run from Visual Studio in debug mode yeilds:

C:\Development\solution folder\application folder\bin\debug

This is the exact behaviour I needed, and its simple and straightforward enough.

The answer is no, but for me I did the following

the script: myExport

#! \bin\bash
export $1

an alias in my .bashrc

alias myExport='source myExport' 

Still you source it, but maybe in this way it is more useable and it is interesting for someone else.

var str = "Text\",\"Text\",\"Text";
var newstr = str.Replace("\",\"", ";");

May be this helps

List<String> l = Arrays.asList("+","-");

Apple cares about security and as you know it is not possible to install any application on a real iOS device. Apple has several legal ways to do it:

• When you need to test/debug an app on a real device the Development Provisioning Profile allows you to do it
• When you publish an app you send a Distribution Provisioning Profile^[About] and Apple after review reassign it by they own key

Development Provisioning Profile is stored on device and contains:

• Application ID - application which are going to run
• List of Development certificates - who can debug the app
• List of devices - which devices can run this app

Xcode by default take cares about

We can get MAC address in Ubuntu by this ways in php

$ipconfig =   shell_exec ("ifconfig -a | grep -Po 'HWaddr \K.*$'");  
    // display mac address   
 echo $ipconfig;

Just replace:

return d.age - d1.age;

By:

return ((Integer)d.age).compareTo(d1.age);

Or invert to reverse the list:

return ((Integer)d1.age).compareTo(d.age);

EDIT:

Fixed the "memory problem".
Indeed, the better solution is change the age field in the Dog class to Integer, because there many benefits, like the null possibility...

I've added the <%% literal tag delimiter as an answer to this because of its obscurity. This will tell erb not to interpret the <% part of the tag which is necessary for js apps like displaying chart.js tooltips etc.

Update (Fixed broken link)

Everything about ERB can now be found here: https://puppet.com/docs/puppet/5.3/lang_template_erb.html#tags

At the time the compiler encounters the call to swapCase in main(), it does not know about the function swapCase, so it reports an error. You can either move the definition of swapCase above main, or declare swap case above main:

void swapCase(char* name);

Also, the 32 in swapCase causes the reader to pause and wonder. The comment helps! In this context, it would add clarity to write

if ('A' <= name[i] && name[i] <= 'Z')
    name[i] += 'a' - 'A';
else if ('a' <= name[i] && name[i] <= 'z')
    name[i] += 'A' - 'a';

The construction in my if-tests is a matter of personal style. Yours were just fine. The main thing is the way to modify name[i] -- using the difference in 'a' vs. 'A' makes it more obvious what is going on, and nobody has to wonder if the '32' is actually correct.

Good luck learning!

Not the answer to the original question but when trying to resolve a similar issue, I found that the Mac OS X update to Maverics screwed up the java install (the cacert actually). Remove sudo rm -rf /Library/Java/JavaVirtualMachines/*.jdk and reinstall from http://www.oracle.com/technetwork/java/javase/downloads/index.html

@Warren and @DCookie have covered the solution, one thing to emphasise is the use of tnsping. You can use this to prove your TNSNames is correct before attempting to connect.

Once you have set up tnsnames correctly you could use ODBC or try TOra which will use your native oracle connection. TOra or something similar (TOAD, SQL*Plus etc) will prove invaluable in debugging and improving your SQL.

Last but not least when you eventually connect with ASP.net remember that you can use the Oracle data connection libraries. See Oracle.com for a host of resources.

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

Your Javascript:

function UserAction() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
         if (this.readyState == 4 && this.status == 200) {
             alert(this.responseText);
         }
    };
    xhttp.open("POST", "Your Rest URL Here", true);
    xhttp.setRequestHeader("Content-type", "application/json");
    xhttp.send("Your JSON Data Here");
}

Your Button action::

<button type="submit" onclick="UserAction()">Search</button>

For more info go through the following link (Updated 2017/01/11)

Your first example is effectively what you need:

<TextBlock Text="{Binding CelsiusTemp, StringFormat={}{0}°C}" />

I happen to be stuck with an FTP server (Rackspace Cloud Sites virtual server) that doesn't seem to support MLSD. Yet I need several fields of file information, such as size and timestamp, not just the filename, so I have to use the DIR command. On this server, the output of DIR looks very much like the OP's. In case it helps anyone, here's a little Python class that parses a line of such output to obtain the filename, size and timestamp.

import datetime

class FtpDir:
    def parse_dir_line(self, line):
        words = line.split()
        self.filename = words[8]
        self.size = int(words[4])
        t = words[7].split(':')
        ts = words[5] + '-' + words[6] + '-' + datetime.datetime.now().strftime('%Y') + ' ' + t[0] + ':' + t[1]
        self.timestamp = datetime.datetime.strptime(ts, '%b-%d-%Y %H:%M')

Not very portable, I know, but easy to extend or modify to deal with various different FTP servers.

This is simple program showing append('t') to the list.
n=['f','g','h','i','k']

for i in range(1):
    temp=[]
    temp.append(n[-2:])
    temp.append('t')
    print(temp)

Output: [['i', 'k'], 't']

var option_user_selection = document.getElementById("maincourse").options[document.getElementById("maincourse").selectedIndex ].text

If the action of each combination is static, you could build a two-dimensional array:

var data = [
  [1,2,3,4,5],
  [6,7,8,9,10],
  [11,12,13,14,15],
  [16,17,18,19,20],
  [21,22,23,24,25]
];

The numbers in above example can be anything, such as string, array, etc. Fetching the value is now a one-liner (assuming sliders have a value range of [0,5):

var info = data[firstSliderValue][secondSliderValue];

Use the -ss option:

ffmpeg -ss 01:23:45 -i input -vframes 1 -q:v 2 output.jpg

• For JPEG output use -q:v to control output quality. Full range is a linear scale of 1-31 where a lower value results in a higher quality. 2-5 is a good range to try.

• The select filter provides an alternative method for more complex needs such as selecting only certain frame types, or 1 per 100, etc.

• Placing -ss before the input will be faster. See FFmpeg Wiki: Seeking and this excerpt from the ffmpeg cli tool documentation:

-ss position (input/output)

When used as an input option (before -i), seeks in this input file to position. Note the in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. When transcoding and -accurate_seek is enabled (the default), this extra segment between the seek point and position will be decoded and discarded. When doing stream copy or when -noaccurate_seek is used, it will be preserved.

When used as an output option (before an output filename), decodes but discards input until the timestamps reach position.

position may be either in seconds or in hh:mm:ss[.xxx] form.

Keep in mind that you're NEVER zooming in on a UIImage. EVER.

Instead, you're zooming in and out on the view that displays the UIImage.

In this particular case, you chould choose to create a custom UIView with custom drawing to display the image, a UIImageView which displays the image for you, or a UIWebView which will need some additional HTML to back it up.

In all cases, you'll need to implement touchesBegan, touchesMoved, and the like to determine what the user is trying to do (zoom, pan, etc.).

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

You can use something like this:

printf("%.2f", number);

If you need to use the string for something other than printing out, use the NumberFormat class:

NumberFormat formatter = new DecimalFormatter("#.##");
String s = formatter.format(3.14159265); // Creates a string containing "3.14"

You can do:

select concat('drop table if exists ', table_name, ' cascade;')
  from information_schema.tables;

Then run the generated queries. They will drop every single table on the current database.

Here is some help on drop table command.

I had issues with some of the above solutions, with getting the correct "bounding_box" or new size of the image. Therefore here is my version

def rotation(image, angleInDegrees):
    h, w = image.shape[:2]
    img_c = (w / 2, h / 2)

    rot = cv2.getRotationMatrix2D(img_c, angleInDegrees, 1)

    rad = math.radians(angleInDegrees)
    sin = math.sin(rad)
    cos = math.cos(rad)
    b_w = int((h * abs(sin)) + (w * abs(cos)))
    b_h = int((h * abs(cos)) + (w * abs(sin)))

    rot[0, 2] += ((b_w / 2) - img_c[0])
    rot[1, 2] += ((b_h / 2) - img_c[1])

    outImg = cv2.warpAffine(image, rot, (b_w, b_h), flags=cv2.INTER_LINEAR)
    return outImg

try this

<iframe name="myIframe" id="myIframe" width="400px" height="400px" runat="server"></iframe>

Expose this iframe in the master page's codebehind:

public HtmlControl iframe
{
get
{
return this.myIframe;
}
}

Add the MasterType directive for the content page to strongly typed Master Page.

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits=_Default" Title="Untitled Page" %>
<%@ MasterType VirtualPath="~/MasterPage.master" %>

In code behind

protected void Page_Load(object sender, EventArgs e)
{
this.Master.iframe.Attributes.Add("src", "some.aspx");
}

Your forms are automatically put into $scope as an object. It can be accessed via $scope[formName]

Below is an example that will work with your original setup and without having to pass the form itself as a parameter in ng-submit.

var controller = function($scope) {

    $scope.login = {
        submit: function() {
            if($scope.loginform.$invalid) return false;

        }
    }

};

Working example: http://plnkr.co/edit/BEWnrP?p=preview

The function below will return the x86 Program Files directory in all of these three Windows configurations:

• 32 bit Windows
• 32 bit program running on 64 bit Windows
• 64 bit program running on 64 bit windows

static string ProgramFilesx86()
{
    if( 8 == IntPtr.Size 
        || (!String.IsNullOrEmpty(Environment.GetEnvironmentVariable("PROCESSOR_ARCHITEW6432"))))
    {
        return Environment.GetEnvironmentVariable("ProgramFiles(x86)");
    }

    return Environment.GetEnvironmentVariable("ProgramFiles");
}

The only way to do explicit scaling in CSS is to use tricks such as found here.

IE6 only, you could also use filters (check out PNGFix). But applying them automatically to the page will need javascript, though that javascript could be embedded in the CSS file.

If you are going to require javascript, then you might want to just have javascript fill in the missing value for the height by inspecting the image once the content has loaded. (Sorry I do not have a reference for this technique).

Finally, and pardon me for this soapbox, you might want to eschew IE6 support in this matter. You could add _width: auto after your width: 75px rule, so that IE6 at least renders the image reasonably, even if it is the wrong size.

I recommend the last solution simply because IE6 is on the way out: 20% and going down almost a percent a month. Also, I note that your site is recreational and in the UK. Both of these help the demographic lean to be away from IE6: IE6 usage drops nearly 40% during weekends (no citation sorry), and UK has a much lower IE6 demographic (again no citation, sorry).

Good luck!

I had this same problem when using a key of 4096 bits:

$ ssh-keygen -t rsa -C "GitLab" -b 4096
$ ssh -vT git@gitlabhost
...
debug1: Offering public key: /home/user/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password
debug1: Trying private key: /home/user/.ssh/id_dsa
debug1: Trying private key: /home/user/.ssh/id_ecdsa
debug1: Next authentication method: password
git@gitlabhost's password:
Connection closed by host

But with the 2048 bit key (the default size), ssh connects to gitlab without prompting for a password (after adding the new pub key to the user's gitlab ssh keys)

$ ssh-keygen -t rsa -C "GitLab"
$ ssh -vT git@gitlabhost
Welcome to GitLab, Joe User!

You can achieve this by setting content mode of image view to UIViewContentModeScaleAspectFill.

Then use following method method to get the resized uiimage object.

- (UIImage*)setProfileImage:(UIImage *)imageToResize onImageView:(UIImageView *)imageView
{
    CGFloat width = imageToResize.size.width;
    CGFloat height = imageToResize.size.height;
    float scaleFactor;
    if(width > height)
    {
        scaleFactor = imageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = imageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), NO, 0.0);
    [imageToResize drawInRect:CGRectMake(0, 0, width * scaleFactor, height * scaleFactor)];
    UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return resizedImage;
}

Edited Here (Swift Version)

func setProfileImage(imageToResize: UIImage, onImageView: UIImageView) -> UIImage
{
    let width = imageToResize.size.width
    let height = imageToResize.size.height

    var scaleFactor: CGFloat

    if(width > height)
    {
        scaleFactor = onImageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = onImageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), false, 0.0)
    imageToResize.drawInRect(CGRectMake(0, 0, width * scaleFactor, height * scaleFactor))
    let resizedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return resizedImage;
}

I made this powershell script to unblock all files on a share on my server

Get-ChildItem "\\ServerName\e$\MyDirectory\" -Recurse -File | % {
       Unblock-File -Path $_.FullName
}

Click on the New file menu, and chose file select language Objective. At that time it automatically generates a "Objective-C Bridging Header" file that is used to define some class name.

"Objective-C Bridging Header" under "Swift Compiler - Code Generation".

add this to your activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if ((keyCode == KeyEvent.KEYCODE_BACK))
    {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}

I want to add another solution: In my case, I need to use a Enum group in a drop down button list items. So they might have space, i.e. more user friendly descriptions needed:

  public enum CancelReasonsEnum
{
    [Description("In rush")]
    InRush,
    [Description("Need more coffee")]
    NeedMoreCoffee,
    [Description("Call me back in 5 minutes!")]
    In5Minutes
}

In a helper class (HelperMethods) I created the following method:

 public static List<string> GetListOfDescription<T>() where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null : Enum.GetValues(t).Cast<Enum>().Select(x => x.GetDescription()).ToList();
    }

When you call this helper you will get the list of item descriptions.

 List<string> items = HelperMethods.GetListOfDescription<CancelReasonEnum>();

ADDITION: In any case, if you want to implement this method you need :GetDescription extension for enum. This is what I use.

 public static string GetDescription(this Enum value)
    {
        Type type = value.GetType();
        string name = Enum.GetName(type, value);
        if (name != null)
        {
            FieldInfo field = type.GetField(name);
            if (field != null)
            {
                DescriptionAttribute attr =Attribute.GetCustomAttribute(field,typeof(DescriptionAttribute)) as DescriptionAttribute;
                if (attr != null)
                {
                    return attr.Description;
                }
            }
        }
        return null;
        /* how to use
            MyEnum x = MyEnum.NeedMoreCoffee;
            string description = x.GetDescription();
        */

    }

Just set the expiration date to one hour ago, if you want to "remove" the cookie, like this:

setcookie ("TestCookie", "", time() - 3600);

or

setcookie ("TestCookie", "", time() - 3600, "/~rasmus/", "example.com", 1);

Source: http://www.php.net/manual/en/function.setcookie.php

You should use the filter_input() function for all globals which a visitor can enter/manipulate, like this:

$visitors_ip = filter_input(INPUT_COOKIE, 'id');

You can read more about it here: http://www.php.net/manual/en/function.filter-input.php and here: http://www.w3schools.com/php/func_filter_input.asp

      return 0 == nameComparisonResult?o1.getAge()-o2.getAge():nameComparisonResult;

   }
 }

Here is another way to reproduce this error in Python2.7 with numpy:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate(a,b)   #note the lack of tuple format for a and b
print(c) 

The np.concatenate method produces an error:

TypeError: only length-1 arrays can be converted to Python scalars

If you read the documentation around numpy.concatenate, then you see it expects a tuple of numpy array objects. So surrounding the variables with parens fixed it:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate((a,b))  #surround a and b with parens, packaging them as a tuple
print(c) 

Then it prints:

[1 2 3 4 5 6]

What's going on here?

That error is a case of bubble-up implementation - it is caused by duck-typing philosophy of python. This is a cryptic low-level error python guts puke up when it receives some unexpected variable types, tries to run off and do something, gets part way through, the pukes, attempts remedial action, fails, then tells you that "you can't reformulate the subspace responders when the wind blows from the east on Tuesday".

In more sensible languages like C++ or Java, it would have told you: "you can't use a TypeA where TypeB was expected". But Python does it's best to soldier on, does something undefined, fails, and then hands you back an unhelpful error. The fact we have to be discussing this is one of the reasons I don't like Python, or its duck-typing philosophy.

You mention that you are doing this because IE doesn't support SVG.

The good news is that IE does support vector graphics. Okay, so it's in the form of a language called VML which only IE supports, rather than SVG, but it is there, and you can use it.

Google Maps, among others, will detect the browser capabilities to determine whether to serve SVG or VML.

Then there's the Raphael library, which is a Javascript browswer-based graphics library, which supports either SVG or VML, again depending on the browser.

Another one which may help: SVGWeb.

All of which means that you can support your IE users without having to resort to bitmap graphics.

See also the top answer to this question, for example: XSL Transform SVG to VML

Google have restricted write access to the external sdcard. From API 19 there is a framework called Storage Access Framework which allows you the set up "contracts" to allow write access.

TL;DR:

• pip install -Iv (i.e. pip install -Iv MySQL_python==1.2.2)

First, I see two issues with what you're trying to do. Since you already have an installed version, you should either uninstall the current existing driver or use pip install -I MySQL_python==1.2.2

However, you'll soon find out that this doesn't work. If you look at pip's installation log, or if you do a pip install -Iv MySQL_python==1.2.2 you'll find that the PyPI URL link does not work for MySQL_python v1.2.2. You can verify this here: http://pypi.python.org/pypi/MySQL-python/1.2.2

The download link 404s and the fallback URL links are re-directing infinitely due to sourceforge.net's recent upgrade and PyPI's stale URL.

So to properly install the driver, you can follow these steps:

pip uninstall MySQL_python
pip install -Iv http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz/download

Wikipedia says:

Method overriding, in object oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

In detail, when you have an object foo that has a void hello() function:

class foo {
    virtual void hello(); // Code : printf("Hello!");
}

A child of foo, will also have a hello() function:

class bar : foo {
    // no functions in here but yet, you can call
    // bar.hello()
}

However, you may want to print "Hello Bar!" when hello() function is being called from a bar object. You can do this using override

class bar : foo {
    virtual void hello() override; // Code : printf("Hello Bar!");
}

I faced the same issue, spent too much calories searching for the right fix until I decided to settle down with file reading:

Properties configProps = new Properties();
InputStream iStream = new ClassPathResource("myapp-test.properties").getInputStream();
InputStream iStream = getConfigFile();
configProps.load(iStream);

A little variation on classes. Initialize it with hashtables.

class Point { $x; $y }

$a = [Point[]] (@{ x=1; y=2 },@{ x=3; y=4 })

$a

x y        
- -          
1 2
3 4

$a.gettype()

In newer version of windows the Certuil has [CertificateStoreName] where we can give the store name. In earlier version windows this was not possible.

Installing *.pfx certificate: certutil -f -p "" -enterprise -importpfx root ""

Installing *.cer certificate: certutil -addstore -enterprise -f -v root ""

For more details below command can be executed in windows cmd. C:>certutil -importpfx -? Usage: CertUtil [Options] -importPFX [CertificateStoreName] PFXFile [Modifiers]

You've gotten some answers, and most of them are correct, but miss what (I think) is probably the point here.

My guess is that you have a makefile you're trying to use to create an executable. In case you're not familiar with them, makefiles list dependencies between files. For a really simple case, it might have something like:

myprogram.exe: myprogram.o
    $(CC) -o myprogram.exe myprogram.o

myprogram.o: myprogram.cpp
    $(CC) -c myprogram.cpp

The first line says that myprogram.exe depends on myprogram.o. The second line tells how to create myprogram.exe from myprogram.o. The third and fourth lines say myprogram.o depends on myprogram.cpp, and how to create myprogram.o from myprogram.cpp` respectively.

My guess is that in your case, you have a makefile like the one above that was created for gcc. The problem you're running into is that you're using it with MS VC instead of gcc. As it happens, MS VC uses ".obj" as the extension for its object files instead of ".o".

That means when make (or its equivalent built into the IDE in your case) tries to build the program, it looks at those lines to try to figure out how to build myprogram.exe. To do that, it sees that it needs to build myprogram.o, so it looks for the rule that tells it how to build myprogram.o. That says it should compile the .cpp file, so it does that.

Then things break down -- the VC++ compiler produces myprogram.obj instead of myprogram.o as the object file, so when it tries to go to the next step to produce myprogram.exe from myprogram.o, it finds that its attempt at creating myprogram.o simply failed. It did what the rule said to do, but that didn't produce myprogram.o as promised. It doesn't know what to do, so it quits and give you an error message.

The cure for that specific problem is probably pretty simple: edit the make file so all the object files have an extension of .obj instead of .o. There's room for a lot of question whether that will fix everything though -- that may be all you need, or it may simply lead to other (probably more difficult) problems.

You could use https://github.com/jankroken/commandline , here's how to do that:

To make this example work, I must make assumptions about what the arguments means - just picking something here...

-r opt1 => replyAddress=opt1
-S opt2 arg1 arg2 arg3 arg4 => subjects=[opt2,arg1,arg2,arg3,arg4]
--test = test=true (default false)
-A opt3 => address=opt3

this can then be set up this way:

public class MyProgramOptions {
  private String replyAddress;
  private String address;
  private List<String> subjects;
  private boolean test = false;

  @ShortSwitch("r")
  @LongSwitch("replyAddress") // if you also want a long variant. This can be skipped
  @SingleArgument
  public void setReplyAddress(String replyAddress) {
    this.replyAddress = replyAddress;
  }

  @ShortSwitch("S")
  @AllAvailableArguments
  public void setSubjects(List<String> subjects) {
    this.subjects = subjects;
  }

  @LongSwitch("test")
  @Toggle(true)
  public void setTest(boolean test) {
    this.test = test;
  }

  @ShortSwitch("A")
  @SingleArgument
  public void setAddress(String address) {
    this.address = address;
  }

  // getters...
}

and then in the main method, you can just do:

public final static void main(String[] args) {
  try {
    MyProgramOptions options = CommandLineParser.parse(MyProgramOptions.class, args, OptionStyle.SIMPLE);

    // and then you can pass options to your application logic...

  } catch
    ...
  }
}

I suggest using ES5 array methods:

["myCircle1","myCircle2","myCircle3","myCircle4"] // Array of IDs
.map(document.getElementById, document)           // Array of elements
.forEach(doStuff);

Then doStuff will be called once for each element, and will receive 3 arguments: the element, the index of the element inside the array of elements, and the array of elements.

The problem is not in your code but in your json:

{"Compemployes":[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]}

this represents an object which contains a property Compemployes which is a list of Employee. In that case you should create that object like:

class EmployeList{
    private List<Employe> compemployes;
    (with getter an setter)
}

and to deserialize the json simply do:

EmployeList employeList = mapper.readValue(jsonString,EmployeList.class);

If your json should directly represent a list of employees it should look like:

[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]

Last remark:

List<Employee> list2 = mapper.readValue(jsonString, 
TypeFactory.collectionType(List.class, Employee.class));

TypeFactory.collectionType is deprecated you should now use something like:

List<Employee> list = mapper.readValue(jsonString,
TypeFactory.defaultInstance().constructCollectionType(List.class,  
   Employee.class));

thought I would add this for any future peeps. It will always make sure that its monday if needed, can also be used to always ensure sunday. For me I always need monday, but local is dependant on the machine being used, and this is an easy fix:

var begin = moment().isoWeekday(1).startOf('week');
var begin2 = moment().startOf('week');
// could check to see if day 1 = Sunday  then add 1 day
// my mac on bst still treats day 1 as sunday    

var firstDay = moment().startOf('week').format('dddd') === 'Sunday' ?     
moment().startOf('week').add('d',1).format('dddd DD-MM-YYYY') : 
moment().startOf('week').format('dddd DD-MM-YYYY');

document.body.innerHTML = '<b>could be monday or sunday depending on client: </b><br />' + 
begin.format('dddd DD-MM-YYYY') + 
'<br /><br /> <b>should be monday:</b> <br>' + firstDay + 
'<br><br> <b>could also be sunday or monday </b><br> ' + 
begin2.format('dddd DD-MM-YYYY');

var a = [];
a.length > 0

I would just check the length. You could potentially wrap it in a helper method if you like.

There are two different types of export, named and default. You can have multiple named exports per module but only one default export. Each type corresponds to one of the above. Source: MDN

Named Export

export class NamedExport1 { }

export class NamedExport2 { }

// Import class
import { NamedExport1 } from 'path-to-file'
import { NamedExport2 } from 'path-to-file'

// OR you can import all at once
import * as namedExports from 'path-to-file'

Default Export

export default class DefaultExport1 { }

// Import class
import DefaultExport1 from 'path-to-file' // No curly braces - {}

// You can use a different name for the default import

import Foo from 'path-to-file' // This will assign any default export to Foo.

In WAMP 3.1.4 x64 I solved updating the file C:\wamp64\alias\phpmyadmin.conf from this:

I have the almost the same situation as yours; that if the screen width is less than the my specified width it should hide the div. This is the jquery code I used that worked for me.

$(window).resize(function() {

  if ($(this).width() < 1024) {

    $('.divIWantedToHide').hide();

  } else {

    $('.divIWantedToHide').show();

    }

});

eventcreate2 allows you to create custom logs, where eventcreate does not.

1. In your terminal, navigate to the repo you want to make the changes in.
2. Execute git config --list to check current username & email in your local repo.
3. Change username & email as desired. Make it a global change or specific to the local repo:
   git config [--global] user.name "Full Name"
git config [--global] user.email "[email protected]"
   
   Per repo basis you could also edit .git/config manually instead.
4. Done!

When performing step 2 if you see credential.helper=manager you need to open the credential manager of your computer (Win or Mac) and update the credentials there

I would use it at every opportunity. See When do you use Java's @Override annotation and why?

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

None of the solutions work if you are using Jenkins build!! When pom is run inside Jenkins build server.. these solutions will fail, as Jenkins run pom will try to download these files from enterprise repository.

Copy jars under src/main/resources/lib (create lib folder). These will be part of your project and go all the way to deployment server. In deployment server, make sure your startup scripts contain src/main/resources/lib/* in classpath. Viola.

Personally I would suggest this is an error as opposed to a setting that needs adjusting. In my code it was because I had a class that had the same name as a library within one of my controllers and it seemed to trip it up.

Output errors and see where this is being triggered.

Adding also Kotlin version with:

• getting text from resources (strings.xml)
• getting color from resources (colors.xml)
• "fetching HEX" moved as extension

fun getMulticolorSpanned(): Spanned {
    // Get text from resources
    val text: String = getString(R.string.your_text_from_resources)

    // Get color from resources and parse it to HEX (RGB) value
    val warningHexColor = getHexFromColors(R.color.your_error_color)

    // Use above string & color in HTML
    val html = "<string>$text<span style=\"color:#$warningHexColor;\">*</span></string>"

    // Parse HTML (base on API version)
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY)
    } else {
        Html.fromHtml(html)
    }
}

And Kotlin extension (with removing alpha):

fun Context.getHexFromColors(
    colorRes: Int
): String {
    val labelColor: Int = ContextCompat.getColor(this, colorRes)
    return String.format("%X", labelColor).substring(2)
}

You should be able to use the Application class in the same way as Winform apps do. Probably the easiest way to start a new project is to do what Marc suggested: create a new Winform project, and then change it in the options to a console application

I created a simplified version using Array.prototype.includes(). My technique is similar to @Kunle Babatunde.

const isVowel = (char) => ["a", "e", "i", "o", "u"].includes(char);_x000D_
_x000D_
console.log(isVowel("o"), isVowel("s"));

Thanks to @LyphTEC that gave a very interesting way to open an Office file in edit mode!

It gave me the idea to change the function _DispEx that is called when the user clicks on a file into a document library. By hacking the original function we can them be able to open a dialog (for Firefox/Chrome) and ask the user if he/she wants to readonly or edit the file:

See below the JavaScript code I used. My code is for Excel files, but it could be modified to work with Word documents too:

    /**
 * fix problem with Excel documents on Firefox/Chrome (see https://blog.kodono.info/wordpress/2017/02/09/how-to-open-an-excel-document-from-sharepoint-files-into-chromefirefox-in-readonlyedit-mode/)
 * @param  {HTMLElement} p the <A> element
 * @param  {HTMLEvent} a the click event
 * @param  {Boolean} h TRUE
 * @param  {Boolean} e FALSE
 * @param  {Boolean} g FALSE
 * @param  {Strin} k the ActiveX command (e.g. "SharePoint.OpenDocuments.3")
 * @param  {Number} c 0
 * @param  {String} o the activeX command, here we look at "SharePoint.OpenDocuments"
 * @param  {String} m
 * @param  {String} b the replacement URL to the xslviewer

ADb used to work fine for me for a week. But now suddenly today it says the machine actively refused connection.

fix:

step 1: go check you phone's IP Adress once again, it keeps changing.
step 2: If it changed. Just use that new IP to connect.

Hope it helped someone :)

to store this unstructured data

As you said, MongoDB is best suitable to store unstructured data. And this can organize your data into document format. These RDBMS altenatives called NoSQL data stores (MongoDB, CouchDB, Voldemort) are very useful for applications that scales massively and require faster data access from these big data stores.

And the implementation of these databases are simpler than the regular RDBMS. Since these are simple key-valued or document style binary objects directly serialized into disk. These data stores don't enforce the ACID properties, and any schemas. This doesn't provide any transaction abilities. So this can scale big and we can achieve faster access (both read and write).

But in contrast, RDBM enforces ACID and schemas on datas. If you wanted to work with structured data you can go ahead with RDBM.

I would choose MySQL for creating forums for this kind of stuff. Because this is not going to scale big. And this is a very simple (common) application which has structured relations among the data.

You can import svg and it use it like a image

System.in.read() is a read input method for System.in class which is "Standard Input file" or 0 in conventional OS.

0 is, by definition, a magic number. EXIT_SUCCESS is almost universally equal to 0, happily enough. So why not just return/exit 0?

exit(EXIT_SUCCESS); is abundantly clear in meaning.

exit(0); on the other hand, is counterintuitive in some ways. Someone not familiar with shell behavior might assume that 0 == false == bad, just like every other usage of 0 in C. But no - in this one special case, 0 == success == good. For most experienced devs, not going to be a problem. But why trip up the new guy for absolutely no reason?

tl;dr - if there's a defined constant for your magic number, there's almost never a reason not to used the constant in the first place. It's more searchable, often clearer, etc. and it doesn't cost you anything.

Brightness and contrast can be adjusted using alpha (a) and beta (ß), respectively. The expression can be written as

OpenCV already implements this as cv2.convertScaleAbs(), just provide user defined alpha and beta values

import cv2

image = cv2.imread('1.jpg')

alpha = 1.5 # Contrast control (1.0-3.0)
beta = 0 # Brightness control (0-100)

adjusted = cv2.convertScaleAbs(image, alpha=alpha, beta=beta)

cv2.imshow('original', image)
cv2.imshow('adjusted', adjusted)
cv2.waitKey()

Before -> After

Note: For automatic brightness/contrast adjustment take a look at automatic contrast and brightness adjustment of a color photo

Configure NLog via XML, but Programmatically

What? Did you know that you can specify the NLog XML directly to NLog from your app, as opposed to having NLog read it from the config file? Well, you can. Let's say that you have a distributed app and you want to use the same configuration everywhere. You could keep a config file in each location and maintain it separately, you could maintain one in a central location and push it out to the satellite locations, or you could probably do a lot of other things. Or, you could store your XML in a database, get it at app startup, and configure NLog directly with that XML (maybe checking back periodically to see if it had changed).

  string xml = @"<nlog>
                   <targets>
                     <target name='console' type='Console' layout='${message}' />
                   </targets>

                   <rules>
                     <logger name='*' minlevel='Error' writeTo='console' />
                   </rules>
                 </nlog>";

  StringReader sr = new StringReader(xml);
  XmlReader xr = XmlReader.Create(sr);
  XmlLoggingConfiguration config = new XmlLoggingConfiguration(xr, null);
  LogManager.Configuration = config;
  //NLog is now configured just as if the XML above had been in NLog.config or app.config

  logger.Trace("Hello - Trace"); //Won't log
  logger.Debug("Hello - Debug"); //Won't log
  logger.Info("Hello - Info");   //Won't log
  logger.Warn("Hello - Warn");   //Won't log
  logger.Error("Hello - Error"); //Will log
  logger.Fatal("Hello - Fatal"); //Will log

  //Now let's change the config (the root logging level) ...
  string xml2 = @"<nlog>
                  <targets>
                     <target name='console' type='Console' layout='${message}' />
                   </targets>

                   <rules>
                     <logger name='*' minlevel='Trace' writeTo='console' />
                   </rules>
                 </nlog>";

  StringReader sr2 = new StringReader(xml2);
  XmlReader xr2 = XmlReader.Create(sr2);
  XmlLoggingConfiguration config2 = new XmlLoggingConfiguration(xr2, null);
  LogManager.Configuration = config2;

  logger.Trace("Hello - Trace"); //Will log
  logger.Debug("Hello - Debug"); //Will log
  logger.Info("Hello - Info");   //Will log
  logger.Warn("Hello - Warn");   //Will log
  logger.Error("Hello - Error"); //Will log
  logger.Fatal("Hello - Fatal"); //Will log

I'm not sure how robust this is, but this example provides a useful starting point for people that might want to try configuring like this.

At the very core, the file extension you use makes no difference as to how perl interprets those files.

However, putting modules in .pm files following a certain directory structure that follows the package name provides a convenience. So, if you have a module Example::Plot::FourD and you put it in a directory Example/Plot/FourD.pm in a path in your @INC, then use and require will do the right thing when given the package name as in use Example::Plot::FourD.

The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with 1; unless you're sure it'll return true otherwise. But it's better just to put the 1;, in case you add more statements.

If EXPR is a bareword, the require assumes a ".pm" extension and replaces "::" with "/" in the filename for you, to make it easy to load standard modules. This form of loading of modules does not risk altering your namespace.

All use does is to figure out the filename from the package name provided, require it in a BEGIN block and invoke import on the package. There is nothing preventing you from not using use but taking those steps manually.

For example, below I put the Example::Plot::FourD package in a file called t.pl, loaded it in a script in file s.pl.

C:\Temp> cat t.pl
package Example::Plot::FourD;

use strict; use warnings;

sub new { bless {} => shift }

sub something { print "something\n" }

"Example::Plot::FourD"

C:\Temp> cat s.pl
#!/usr/bin/perl
use strict; use warnings;

BEGIN {
    require 't.pl';
}

my $p = Example::Plot::FourD->new;
$p->something;


C:\Temp> s
something

This example shows that module files do not have to end in 1, any true value will do.

use absolute path where the image actually exists (e.g) '/home/artitra/pictures/filename.jpg'

or create static folder inside your project directory like this

| templates
   - static/
         - images/
              - yourimagename.jpg

then do this

app = Flask(__name__, static_url_path='/static')

then you can access your image like this in index.html

src ="/static/images/yourimage.jpg" 

in img tag

Add this library into build.gradle

A PendingIntent is a token that you give to a foreign application (e.g. NotificationManager, AlarmManager, Home Screen AppWidgetManager, or other 3rd party applications), which allows the foreign application to use your application's permissions to execute a predefined piece of code.

If you give the foreign application an Intent, it will execute your Intent with its own permissions. But if you give the foreign application a PendingIntent, that application will execute your Intent using your application's permission.

In order to do this, you need to have a small program that displays a messagebox and run that from your batch file.

You could open a console window that displays a prompt though, but getting a GUI message box using cmd.exe and friends only is not possible, AFAIK.

A wrapper class is a class that "wraps" around something else, just like its name.

The more formal definition of it would be a class that implements the Adapter Pattern. This allows you to modify one set of APIs into a more usable, readable form. For example, in C#, if you want to use the native Windows API, it helps to wrap it into a class that conforms to the .NET design guidelines.

@SchizoDuckie's answer is very elegant and lightweight, but due to Webkit's lack of implementation for scrollHeight (see here), does not work on Webkit-based browsers (Safari, Chrome, various and sundry mobile platforms).

For this basic idea to work on Webkit along with Gecko and Trident browsers, one need only replace

<body onload='parent.resizeIframe(document.body.scrollHeight)'>

with

<body onload='parent.resizeIframe(document.body.offsetHeight)'>

So long as everything is on the same domain, this works quite well.

adekbadek commented on Nov 11, 2015 It should be mentioned that you don't have to put the images in Images.xcassets - you just put them in the project root and then just require('./myimage.png') as @anback wrote Look at this SO answer and the pull it references

The best bet is to use the numpy library.

from numpy import ndarray

a = ndarray((5,),int)

It doesn't always need to be toolkit-dependent or one doesn't always need use the FontMetrics approach since it requires one to first obtain a graphics object which is absent in a web container or in a headless enviroment.

I have tested this in a web servlet and it does calculate the text width.

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

...

String text = "Hello World";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);     
Font font = new Font("Tahoma", Font.PLAIN, 12);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());

Add the necessary values to these dimensions to create any required margin.

converting object id to string(using toString() method) will do the job.

You can use the ESCAPE keyword with LIKE. Simply prepend the desired character (e.g. '!') to each of the existing % signs in the string and then add ESCAPE '!' (or your character of choice) to the end of the query.

For example:

SELECT *
FROM prices
WHERE discount LIKE '%80!% off%'
ESCAPE '!'

This will make the database treat 80% as an actual part of the string to search for and not 80(wildcard).

MSDN Docs for LIKE

How about:

import java.io.File;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;

public class Demo {

    public static void main(String[] args) throws Exception {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document document = db.parse(new File("input.xml"));
        NodeList nodeList = document.getElementsByTagName("Item");
        for(int x=0,size= nodeList.getLength(); x<size; x++) {
            System.out.println(nodeList.item(x).getAttributes().getNamedItem("name").getNodeValue());
        }
    }
}

Run it through a fairly simple regex: [^a-zA-Z]

And then check it's length separately:

if(string.Length > 7)

Take a look at the Cookie Plugin for jQuery.

I don't know if anything changed in the appcompat library but it's fairly trivial, no need for reflection.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

// loop through all toolbar children right after setting support 
// action bar because the text view has no id assigned

// also make sure that the activity has some title here
// because calling setText() with an empty string actually
// removes the text view from the toolbar

TextView toolbarTitle = null;
for (int i = 0; i < toolbar.getChildCount(); ++i) {
    View child = toolbar.getChildAt(i);

    // assuming that the title is the first instance of TextView
    // you can also check if the title string matches
    if (child instanceof TextView) {
        toolbarTitle = (TextView)child;
        break;
    }
}

One option would be

const styleElement = getComputedStyle(document.getElementById("myDiv"));
console.log(styleElement.height);

Simply You Can Use It

    $sql="select * from tbl_publication where id='5'";
    $result=mysql_query($sql);
    $res=mysql_fetch_array($result);
    //Getting File Name From DB
    $pdfname = $res1['pdfname'];
    //pdf is directory where file exist
    unlink("pdf/".$pdfname);

You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container's value type) must be both copy constructible and assignable. Arrays are neither.

You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x:

std::vector<std::array<double, 4> >

(You'll want to replace std::array with std::tr1::array to use the template included in C++ TR1, or boost::array to use the template from the Boost libraries. Alternatively, you can write your own; it's quite straightforward.)

To answer your question:

If we can have inner private class then why can't we have outer private class...?

You can, the distinction is that the inner class is at the "class" access level, whereas the "outer" class is at the "package" access level. From the Oracle Tutorials:

If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes — you will learn about them in a later lesson.)

Thus, package-private (declaring no modifier) is the effect you would expect from declaring an "outer" class private, the syntax is just different.

Nuru answer actually works, only thing is remove this line frame = cv2.flip(frame,0) under if ret==True: loop which will output the video file without flipping

For apache-tomcat-8.5.28 version just do this,

catalina.bat jpda start

As the default settings already configured for us in catalina.bat as

if not "%JPDA_OPTS%" == "" goto gotJpdaOpts set JPDA_OPTS=-agentlib:jdwp=transport=%JPDA_TRANSPORT%,address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%

So no need of any other config. And when you execute command catalina.bat jpda start, you can see debug port 8000 is opened.

Another option would be to add engine='python' to the command pandas.read_csv(filename, sep='\t', engine='python')

The following complete example will read an existing server.xml file from the current directory, append a new Server and re-write the file to server.xml. It does not work without an existing .xml file, so you will need to modify the code to handle that case.

import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;

public class AddXmlNode {
    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse("server.xml");
        Element root = document.getDocumentElement();

        Collection<Server> servers = new ArrayList<Server>();
        servers.add(new Server());

        for (Server server : servers) {
            // server elements
            Element newServer = document.createElement("server");

            Element name = document.createElement("name");
            name.appendChild(document.createTextNode(server.getName()));
            newServer.appendChild(name);

            Element port = document.createElement("port");
            port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
            newServer.appendChild(port);

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StreamResult result = new StreamResult("server.xml");
        transformer.transform(source, result);
    }

    public static class Server {
        public String getName() { return "foo"; }
        public Integer getPort() { return 12345; }
    }
}

Example server.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
  <server>
    <name>something</name>
    <port>port</port>
  </server>
</Servers>

The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml and then just appends a new Server element and re-writes the file.

TemplateBinding - More limiting than using regular Binding

• More efficient than a Binding but it has less functionality
• Only works inside a ControlTemplate's visual tree
• Doesn't work with properties on Freezables
• Doesn't work within a ControlTemplate's Trigger
• Provides a shortcut in setting properties(not as verbose),e.g. {TemplateBinding targetProperty}

Regular Binding - Does not have above limitations of TemplateBinding

• Respects Parent Properties
• Resets Target Values to clear out any explicitly set values
• Example: <Ellipse Fill="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Background}"/>

If I'm not mistaken you're looking for the FolderBrowserDialog (hence the naming):

var dialog = new System.Windows.Forms.FolderBrowserDialog();
System.Windows.Forms.DialogResult result = dialog.ShowDialog();

Also see this SO thread: Open directory dialog

If your project does not use stdafx.h, you can put the following lines as the first lines in your .cpp file and the compiler warning should go away -- at least it did for me in Visual Studio C++ 2008.

#ifdef _CRT_SECURE_NO_WARNINGS
#undef _CRT_SECURE_NO_WARNINGS
#endif
#define _CRT_SECURE_NO_WARNINGS 1

It's ok to have comment and blank lines before them.

Try this example:

exec DBMS_LOCK.sleep(5);

This is the whole script:

SELECT TO_CHAR (SYSDATE, 'MM-DD-YYYY HH24:MI:SS') "Start Date / Time" FROM DUAL;

exec DBMS_LOCK.sleep(5);

SELECT TO_CHAR (SYSDATE, 'MM-DD-YYYY HH24:MI:SS') "End Date / Time" FROM DUAL;

replace your image tag with

<img src="http://localhost:6054/wp-content/themes/BLANK-Theme/images/material/images.jpg" alt="the-buzz-img3"  style="width:640px;height:360px" />

use style attribute and make sure there is no css class for image which set image height and width

        the_list = the_list[chunk_size:]
    return result_list

a_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

print split_list(a_list, 3)

result:

I got the same error because the remote SID specified was wrong:

 > sqlplus $DATASOURCE_USERNAME/$DATASOURCE_PASSWORD@$DB_SERVER_URL/$REMOTE_SID 

I queried the system database:

select * from global_name;

and found my remote SID ("XE").

Then I could connect without any problem.

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

npm i -D @angular/material @angular/cdk @angular/animations

With the advent of .NET 4.0 (and higher) with the Stream.CopyTo() methods, I thought I would post an updated approach.

I also think the below version is useful as a clear example of a self-contained class for compressing regular strings to Base64 encoded strings, and vice versa:

public static class StringCompression
{
    /// <summary>
    /// Compresses a string and returns a deflate compressed, Base64 encoded string.
    /// </summary>
    /// <param name="uncompressedString">String to compress</param>
    public static string Compress(string uncompressedString)
    {
        byte[] compressedBytes;

        using (var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString)))
        {
            using (var compressedStream = new MemoryStream())
            { 
                // setting the leaveOpen parameter to true to ensure that compressedStream will not be closed when compressorStream is disposed
                // this allows compressorStream to close and flush its buffers to compressedStream and guarantees that compressedStream.ToArray() can be called afterward
                // although MSDN documentation states that ToArray() can be called on a closed MemoryStream, I don't want to rely on that very odd behavior should it ever change
                using (var compressorStream = new DeflateStream(compressedStream, CompressionLevel.Fastest, true))
                {
                    uncompressedStream.CopyTo(compressorStream);
                }

                // call compressedStream.ToArray() after the enclosing DeflateStream has closed and flushed its buffer to compressedStream
                compressedBytes = compressedStream.ToArray();
            }
        }

        return Convert.ToBase64String(compressedBytes);
    }

    /// <summary>
    /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
    /// </summary>
    /// <param name="compressedString">String to decompress.</param>
    public static string Decompress(string compressedString)
    {
        byte[] decompressedBytes;

        var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

        using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
        {
            using (var decompressedStream = new MemoryStream())
            {
                decompressorStream.CopyTo(decompressedStream);

                decompressedBytes = decompressedStream.ToArray();
            }
        }

        return Encoding.UTF8.GetString(decompressedBytes);
    }

Here’s another approach using the extension methods technique to extend the String class to add string compression and decompression. You can drop the class below into an existing project and then use thusly:

var uncompressedString = "Hello World!";
var compressedString = uncompressedString.Compress();

and

var decompressedString = compressedString.Decompress();

To wit:

public static class Extensions
{
    /// <summary>
    /// Compresses a string and returns a deflate compressed, Base64 encoded string.
    /// </summary>
    /// <param name="uncompressedString">String to compress</param>
    public static string Compress(this string uncompressedString)
    {
        byte[] compressedBytes;

        using (var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString)))
        {
            using (var compressedStream = new MemoryStream())
            { 
                // setting the leaveOpen parameter to true to ensure that compressedStream will not be closed when compressorStream is disposed
                // this allows compressorStream to close and flush its buffers to compressedStream and guarantees that compressedStream.ToArray() can be called afterward
                // although MSDN documentation states that ToArray() can be called on a closed MemoryStream, I don't want to rely on that very odd behavior should it ever change
                using (var compressorStream = new DeflateStream(compressedStream, CompressionLevel.Fastest, true))
                {
                    uncompressedStream.CopyTo(compressorStream);
                }

                // call compressedStream.ToArray() after the enclosing DeflateStream has closed and flushed its buffer to compressedStream
                compressedBytes = compressedStream.ToArray();
            }
        }

        return Convert.ToBase64String(compressedBytes);
    }

    /// <summary>
    /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
    /// </summary>
    /// <param name="compressedString">String to decompress.</param>
    public static string Decompress(this string compressedString)
    {
        byte[] decompressedBytes;

        var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

        using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
        {
            using (var decompressedStream = new MemoryStream())
            {
                decompressorStream.CopyTo(decompressedStream);

                decompressedBytes = decompressedStream.ToArray();
            }
        }

        return Encoding.UTF8.GetString(decompressedBytes);
    }

This will work in all JavaScript implementations:

var keys = [];

for (var key in driversCounter) {
    if (driversCounter.hasOwnProperty(key)) {
        keys.push(key);
    }
}

Like others mentioned before you may use Object.keys, but it may not work in older engines. So you can use the following monkey patch:

if (!Object.keys) {
    Object.keys = function (object) {
        var keys = [];

        for (var key in object) {
            if (object.hasOwnProperty(key)) {
                keys.push(key);
            }
        }
    }
}

It's been a while since this question was asked. As of today (matplotlib 2.2.2) and after some reading and trials, I think the best/proper way is the following:

Matplotlib has a module named ticker that "contains classes to support completely configurable tick locating and formatting". To modify a specific tick from the plot, the following works for me:

import matplotlib.pyplot as plt
import matplotlib.ticker as mticker
import numpy as np 

def update_ticks(x, pos):
    if x == 0:
        return 'Mean'
    elif pos == 6:
        return 'pos is 6'
    else:
        return x

data = np.random.normal(0, 1, 1000)
fig, ax = plt.subplots()
ax.hist(data, bins=25, edgecolor='black')
ax.xaxis.set_major_formatter(mticker.FuncFormatter(update_ticks))
plt.show()

Caveat! x is the value of the tick and pos is its relative position in order in the axis. Notice that pos takes values starting in 1, not in 0 as usual when indexing.

In my case, I was trying to format the y-axis of a histogram with percentage values. mticker has another class named PercentFormatter that can do this easily without the need to define a separate function as before:

import matplotlib.pyplot as plt
import matplotlib.ticker as mticker
import numpy as np 

data = np.random.normal(0, 1, 1000)
fig, ax = plt.subplots()
weights = np.ones_like(data) / len(data)
ax.hist(data, bins=25, weights=weights, edgecolor='black')
ax.yaxis.set_major_formatter(mticker.PercentFormatter(xmax=1.0, decimals=1))
plt.show()

In this case xmax is the data value that corresponds to 100%. Percentages are computed as x / xmax * 100, that's why we fix xmax=1.0. Also, decimals is the number of decimal places to place after the point.

If you want to detect the status of navigation bar wether it is hidden/shown. You can simply use following code to detect -

if self.navigationController?.isNavigationBarHidden{
    print("Show navigation bar")
} else {
    print("hide navigation bar")
}

After the merge, it's safe to delete the branch:

git branch -d branch1

Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).

There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.

If you also want to delete the branch on a remote host, you can do:

git push origin :branch1

This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).

git reflog shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck will be the tool of choice at any case of commit-loss in git.

There is a known bug with specifying default command timeout within the EF connection string.

http://bugs.mysql.com/bug.php?id=56806

Remove the value from the connection string and set it on the data context object itself. This will work if you remove the conflicting value from the connection string.

Entity Framework Core 1.0:

this.context.Database.SetCommandTimeout(180);

Entity Framework 6:

this.context.Database.CommandTimeout = 180;

Entity Framework 5:

((IObjectContextAdapter)this.context).ObjectContext.CommandTimeout = 180;

Entity Framework 4 and below:

this.context.CommandTimeout = 180;

I realize this is a very old thread, but it was very helpful when I had to put together some system documentation for several different servers that were hosting different versions of Sql Server. I ended up creating 4 stored procedures which I am posting here for the benefit of the community. We use Dynamics NAV so the two stored procedures with NAV in the name split the Nav company out of the table name. Enjoy...

AngularStrap doesn't work in IE8 with angularjs version 1.2.9 so not use this if your application needs to support IE8

For my case, my original Android SDK Build-tools version is 24 and Andoid SDK Tools version is 25.1.7. I install Android SDK Build-tools version 23.0.3 by Andoird SDK manager.

Modify these 2 lines to:

buildToolsVersion "23.0.3" compileSdkVersion 24

Then it works!

Semaphore allows multiple threads (up to a set number) to access a shared object. Monitors allow mutually exclusive access to a shared object.

$q->execute();
$table_fields = $q->fetchAll(PDO::FETCH_COLUMN);

Since you are using $.ajax, and not $.getJSON, your return type is plain text. you need to now convert data into a JSON object.

you can either do this by changing your $.ajax to $.getJSON (which is a shorthand for $.ajax, only preconfigured to fetch json).

Or you can parse the data string into JSON after you receive it, like so:

    success: function (data) {
         var obj = $.parseJSON(data);
         console.log(obj);
    },

names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
  print (names)
end

1. You're deleting your table and replacing it with an int
2. You aren't pulling a value from the table

Try:

names = {'John','Joe','Steve'}
for i = 1,3 do
    print(names[i])
end

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.

Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.

However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.

A complete function in DB2 SQL that accounts for the leap year 1900 error:

SELECT
   DAYS(INPUT_DATE)                 
   - DAYS(DATE('1899-12-30'))
   - CASE                       
        WHEN INPUT_DATE < DATE('1900-03-01')  
           THEN 1               
           ELSE 0               
     END

1. Go to your React-native Project -> Android
2. Create a file local.properties
3. Open the file

4. paste your Android SDK path like below

   • in Windows sdk.dir = C:\\Users\\USERNAME\\AppData\\Local\\Android\\sdk
   • in macOS sdk.dir = /Users/USERNAME/Library/Android/sdk
   • in linux sdk.dir = /home/USERNAME/Android/Sdk

Replace USERNAME with your user name

Now, Run the react-native run-android in your terminal.

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.

You're close, but you want name to be an XAttribute rather than XElement:

 XDocument doc = XDocument.Load(spath); 
 XElement root = new XElement("Snippet"); 
 root.Add(new XAttribute("name", "name goes here")); 
 root.Add(new XElement("SnippetCode", "SnippetCode")); 
 doc.Element("Snippets").Add(root); 
 doc.Save(spath); 

Here is a quick and dirty solution which takes uploaded file contents from the HTTP body and writes it to a file. I included a "bare bones" HTML/JS snippet for the file upload.

Web API Method:

[Route("api/myfileupload")]        
[HttpPost]
public string MyFileUpload()
{
    var request = HttpContext.Current.Request;
    var filePath = "C:\\temp\\" + request.Headers["filename"];
    using (var fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
    {
        request.InputStream.CopyTo(fs);
    }
    return "uploaded";
}

HTML File Upload:

<form>
    <input type="file" id="myfile"/>  
    <input type="button" onclick="uploadFile();" value="Upload" />
</form>
<script type="text/javascript">
    function uploadFile() {        
        var xhr = new XMLHttpRequest();                 
        var file = document.getElementById('myfile').files[0];
        xhr.open("POST", "api/myfileupload");
        xhr.setRequestHeader("filename", file.name);
        xhr.send(file);
    }
</script>

In Java, you use constructors to overload classes and allow for multiple input parameters. In python, you can use kwargs to provide similar behavior.

java example: https://beginnersbook.com/2013/05/constructor-overloading/

python example:

class Robot():
    # name is an arg and color is a kwarg
    def __init__(self,name, color='red'):
        self.name = name
        self.color = color

red_robot = Robot('Bob')
blue_robot = Robot('Bob', color='blue')

print("I am a {color} robot named {name}.".format(color=red_robot.color, name=red_robot.name))
print("I am a {color} robot named {name}.".format(color=blue_robot.color, name=blue_robot.name))

>>> I am a red robot named Bob.
>>> I am a blue robot named Bob.

just another way to think about it.

an option that worked for me, define the field in the original form as:

forms.CharField(widget = forms.HiddenInput(), required = False)

then when you override it in the new Class it will keep it's place.

Invoking javap to read the bytecode

The javap command takes class-names without the .class extension. Try

javap -c ClassName

Converting .class files back to .java files

javap will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.

To actually decompile (i.e., do the reverse of javac) you will have to use proper decompiler. See for instance the following related question:

• How do I "decompile" Java class files?

You can first cast object to string and then cast the string to int; for example:

string str_myobject = myobject.ToString();
int int_myobject = int.Parse(str_myobject);

this worked for me.

I had the same problem before and I got the solution for it.

I just added the libraries that had the another version but with the same version of my support:appcompat.

For your error for example :

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0

*The solution is to compile the versions of these libraries like that :

compile 'com.android.support:mediarouter-v7:25.1.1'

-if another library had the same issue and had another version just compile it with your support:appcompat version

This resolved my problem and I hope it resolves yours.

Best wishes :)

The difference between
git push origin <branch>
and
git push --set-upstream origin <branch>
is that they both push just fine to the remote repository, but it's when you pull that you notice the difference.

If you do:
git push origin <branch>
when pulling, you have to do:
git pull origin <branch>

But if you do:
git push --set-upstream origin <branch>
then, when pulling, you only have to do:
git pull

So adding in the --set-upstream allows for not having to specify which branch that you want to pull from every single time that you do git pull.

If you are dealing with a lower level time object (I often just use integers), and don't want to write a custom filter for whatever reason, an approach I use is to pass the strftime function into the template as a variable, where it can be called where you need it.

For example:

import time
context={
    'now':int(time.time()),
    'strftime':time.strftime }  # Note there are no brackets () after strftime
                                # This means we are passing in a function, 
                                # not the result of a function.

self.response.write(jinja2.render_template('sometemplate.html', **context))

Which can then be used within sometemplate.html:

<html>
    <body>
        <p>The time is {{ strftime('%H:%M%:%S',now) }}, and 5 seconds ago it was {{ strftime('%H:%M%:%S',now-5) }}.
    </body>
</html>

You need to include the jQuery library on your page.

You can download jQuery here and host it yourself or you can link from an external source like from Google or Microsoft.

Google's:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>

Microsoft's:

<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.6.2.min.js">

You can also use the java.util.Scanner class.

private static void readFileWithScanner() {
    File file = new File("path/to/your/file/file.txt");

    Scanner scan = null;

    try {
        scan = new Scanner(file);

        while (scan.hasNextLine()) {
            String line = scan.nextLine();
            String[] lineArray = line.split(",");
            // do something with lineArray, such as instantiate an object
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } finally {
        scan.close();
    }
}

It does seem a little cumbersome to ignore files (and folders) in Team Foundation Server. I've found a couple ways to do this (using TFS / Team Explorer / Visual Studio 2008). These methods work with the web site ASP project type, too.

One way is to add a new or existing item to a project (e.g. right click on project, Add Existing Item or drag and drop from Windows explorer into the solution explorer), let TFS process the file(s) or folder, then undo pending changes on the item(s). TFS will unmark them as having a pending add change, and the files will sit quietly in the project and stay out of TFS.

Another way is with the Add Items to Folder command of Source Control Explorer. This launches a small wizard, and on one of the steps you can select items to exclude (although, I think you have to add at least one item to TFS with this method for the wizard to let you continue).

You can even add a forbidden patterns check-in policy (under Team -> Team Project Settings -> Source Control... -> Check-in Policy) to disallow other people on the team from mistakenly checking in certain assets.

this bellow solution worked for me

$result_encr="##Sƒ";

iconv("cp1252", "utf-8//IGNORE", $result_encr);

You can use

window.clipboardData.getData('Text')

to get the content of user's clipboard in IE. However, in other browser you may need to use flash to get the content, since there is no standard interface to access the clipboard. May be you can have try this plugin Zero Clipboard

If it helps...

I use the PHP function number_format() and the Narrow No-break Space ( ). It is often used as an unambiguous thousands separator.

echo number_format(200000, 0, "", " ");

Because IE8 has some problems to render the Narrow No-break Space, I changed it for a SPAN

echo "<span class='number'>".number_format(200000, 0, "", "<span></span>")."</span>";

.number SPAN{
    padding: 0 1px; 
}

There is also:

try:
    del mydict[key]
except KeyError:
    pass

This only does 1 lookup instead of 2. However, except clauses are expensive, so if you end up hitting the except clause frequently, this will probably be less efficient than what you already have.

You can install ANT through macports or homebrew.

But if you want to do without 3rd party package managers, the problem can simply be fixed by downloading the binary release from the apache ANT web site and adding the binary to your system PATH.

For example, on Mountain Lion, in ~/.bash_profile and ~/.bashrc my path was setup like this:

export ANT_HOME="/usr/share/ant"
export PATH=$PATH:$ANT_HOME/bin

So after uncompressing apache-ant-1.9.2-bin.tar.bz2 I moved the resulting directory to /usr/share/ and renamed it ant.

Simple as that, the issue is fixed.

Note Don't forget to sudo chown -R root:wheel /usr/share/ant

Here's a solution that uses more modern syntax and is less verbose than the ones already provided:

const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");

video.addEventListener('play', () => {
  function step() {
    ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
    requestAnimationFrame(step)
  }
  requestAnimationFrame(step);
})

Some useful links:

• MDN Documentation for window.requestAnimationFrame()
• Can I use requestAnimationFrame?

You can try this:

//custom date for example
$d1 = new DateTime("2012-07-08");
$d2 = new DateTime("2012-07-11");
$d3 = new DateTime("2012-07-08");
$d4 = new DateTime("2012-07-15");

//create a date period object
$interval = new DateInterval('P1D');
$daterange = iterator_to_array(new DatePeriod($d1, $interval, $d2));
$daterange1 = iterator_to_array(new DatePeriod($d3, $interval, $d4));
array_map(function($v) use ($daterange1) { if(in_array($v, $daterange1)) print "Bingo!";}, $daterange);

SQL Injection can be done on any input the user can influence that isn't properly escaped before used in a query.

One example would be a get variable like this:

http//www.example.com/user.php?userid=5

Now, if the accompanying PHP code goes something like this:

$query = "SELECT username, password FROM users WHERE userid=" . $_GET['userid'];
// ...

You can easily use SQL injection here too:

http//www.example.com/user.php?userid=5 AND 1=2 UNION SELECT password,username FROM users WHERE usertype='admin'

(of course, the spaces will have to be replaced by %20, but this is more readable. Additionally, this is just an example making some more assumptions, but the idea should be clear.)

In a very general way and to support SQL server here is

SELECT TOP(N) *
FROM tbl_name
ORDER BY tbl_id DESC

and for the performance, it is not bad (less than one second for more than 10,000 records On Server machine)

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

My experience shows that the -o option doesn't work properly and that the go-offline goal is far from sufficient to allow a full offline build:

The solution I could validate includes the use of the --legacy-local-repository maven option rather than the -o (offline) one and the use of the local repository in place of the distribution repository

In addition, I had to copy every maven-metadata-maven2_central.xml files of the local-repo into the maven-metadata.xml form expected by maven.

See the solution I found here.

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {

      @if $pos == right {
        top:$dropdown-width * -0.6;

      }
    }
  }

      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}
