Programs & Examples On #Authenticode

What I did was peculiar but somehow it fixed the problem. Pick any project and perform a fake edit of the build.properties file (e.g., add and remove a space and then save the file). Clean and rebuild the projects in your workspace.

Hope this solve some of your problems.

Python lists translate to JSON arrays. What it is giving you is a perfectly valid JSON string that could be used in a Javascript application. To get what you expected, you would need to use a dict:

>>> json.dumps({'apple': 'cat', 'banana':'dog', 'pear':'fish'})
'{"pear": "fish", "apple": "cat", "banana": "dog"}'

Select A.ARIDNR,A.LIEFNR
from Table A
join Table B
on A.ARIDNR = B.ARIDNR
and A.LIEFNR<> B.LIEFNR
group by A.ARIDNR,A.LIEFNR

As (Bourne) shell variables cannot contain dots you can replace them by underscores. Read every line, translate . in the key to _ and evaluate.

#/bin/sh

file="./app.properties"

if [ -f "$file" ]
then
  echo "$file found."

  while IFS='=' read -r key value
  do
    key=$(echo $key | tr '.' '_')
    eval ${key}=\${value}
  done < "$file"

  echo "User Id       = " ${db_uat_user}
  echo "user password = " ${db_uat_passwd}
else
  echo "$file not found."
fi

Note that the above only translates . to _, if you have a more complex format you may want to use additional translations. I recently had to parse a full Ant properties file with lots of nasty characters, and there I had to use:

key=$(echo $key | tr .-/ _ | tr -cd 'A-Za-z0-9_')

Try this on the PowerShell command line:

. .\MyFunctions.ps1
A1

The dot operator is used for script include.

This one is working perfect

QColorDialog *dialog = new QColorDialog(this);
QColor color=  dialog->getColor();
QVariant variant= color;
QString colcode = variant.toString();
ui->label->setStyleSheet("QLabel { background-color :"+colcode+" ; color : blue; }");

getColor() method returns the selected color. You can change label color using stylesheet

I imagine that you define your image something like this:

<img id="image_portrait" src="" alt="chef etat"  width="120" height="135"  />

You can simply load/update image for this tag and chage/set atts (width,height):

var imagelink;
var height;
var width;
$("#image_portrait").attr("src", imagelink);
$("#image_portrait").attr("width", width);
$("#image_portrait").attr("height", height);

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

In the end I changed the following css entry in bootstrap.css

textarea:focus,
input[type="text"]:focus,
input[type="password"]:focus,
input[type="datetime"]:focus,
input[type="datetime-local"]:focus,
input[type="date"]:focus,
input[type="month"]:focus,
input[type="time"]:focus,
input[type="week"]:focus,
input[type="number"]:focus,
input[type="email"]:focus,
input[type="url"]:focus,
input[type="search"]:focus,
input[type="tel"]:focus,
input[type="color"]:focus,
.uneditable-input:focus {   
  border-color: rgba(126, 239, 104, 0.8);
  box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(126, 239, 104, 0.6);
  outline: 0 none;
}

The real problem of why you are getting the error is not that there is anything wrong with your code: you can use either iloc, loc, or apply, or *=, another of them could have worked.

The real problem that you have is due to how you created the df DataFrame. Most likely you created your df as a slice of another DataFrame without using .copy(). The correct way to create your df as a slice of another DataFrame is df = original_df.loc[some slicing].copy().

The problem is already stated in the error message you got " SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead"
You will get the same message in the most current version of pandas too.

Whenever you receive this kind of error message, you should always check how you created your DataFrame. Chances are you forgot the .copy()

Try this approach:

SELECT TOP @offset a.*
FROM (select top @limit b.*, COUNT(*) OVER() totalrows 
        from TABLENAME b order by id asc) a
ORDER BY id desc;

I often need to run an X command on a server that is running many X servers, so the ps based answers do not work. Naturally, $DISPLAY has to be set appropriately. To check that that is valid, use xset q in some fragment like:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

EDIT

Some people find that xset can pause for a annoying amount of time before deciding that $DISPLAY is not pointing at a valid X server (often when tcp/ip is the transport). The fix of course is to use timeout to keep the pause amenable, 1 second say.

if ! timeout 1s xset q &>/dev/null; then
    ?

here is simple solution for that problem, no needs for that 'cat walk' on keyboard, i mean regex :)) enjoy ^-^

user = input('Input: ') # user = 'foobar12345'
int_list, str_list = [], []

for item in user:
 try:
    item = int(item)  # searching for integers in your string
  except:
    str_list.append(item)
    string = ''.join(str_list)
  else:  # if there are integers i will add it to int_list but as str, because join function only can work with str
    int_list.append(str(item))
    integer = int(''.join(int_list))  # if you want it to be string just do z = ''.join(int_list)

final = [string, integer]  # you can also add it to dictionary d = {string: integer}
print(final)

If you want to open a windows file explorer, you should call explorer.exe

Call Shell("explorer.exe" & " " & "P:\Engineering", vbNormalFocus)

Equivalent syxntax

Shell "explorer.exe" & " " & "P:\Engineering", vbNormalFocus

SELECT * FROM tableName WHERE columnName LIKE "%#%" OR columnName LIKE "%$%" OR (etc.)

Completely untested, but this should work:

View positiveButton = findViewById(R.id.positiveButton);
RelativeLayout.LayoutParams layoutParams = 
    (RelativeLayout.LayoutParams)positiveButton.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
positiveButton.setLayoutParams(layoutParams);

add android:configChanges="orientation|screenSize" inside your activity in your manifest

I can think of a cheeky way to do it, I don't think this will be the best option but it will work.

Create the header as a separate table then place the other in a div and set a max size, then allow the scroll to come in by using overflow.

table {_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
.scroll {_x000D_
  max-height: 60px;_x000D_
  overflow: auto;_x000D_
}

<table border="1">_x000D_
  <tr>_x000D_
  <th>head1</th>_x000D_
  <th>head2</th>_x000D_
  <th>head3</th>_x000D_
  <th>head4</th>_x000D_
  </tr>_x000D_
</table>_x000D_
<div class="scroll">_x000D_
  <table>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>More Text</td><td>More Text</td><td>More Text</td><td>More Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td></tr>_x000D_
  </table>_x000D_
</div>

Since some of the functions depend on other libraries like GEOS and proj4 you might want to get their versions too. Then use:

SELECT PostGIS_full_version();

cwait is a general solution for limiting concurrent executions of any functions that return promises.

In your case the code could be something like:

var Promise = require('bluebird');
var cwait = require('cwait');

// Allow max. 10 concurrent file reads.
var queue = new cwait.TaskQueue(Promise, 10);
var read = queue.wrap(Promise.promisify(batchingReadFile));

Promise.map(files, function(filename) {
    console.log(filename);
    return(read(filename));
})

This error happened to me because I had @@model instead of @model... copy & paste error in my case. Changing to @model fixed it for me.

You can implement a SoapExtension that logs the full request and response to a log file. You can then enable the SoapExtension in the web.config, which makes it easy to turn on/off for debugging purposes. Here is an example that I have found and modified for my own use, in my case the logging was done by log4net but you can replace the log methods with your own.

public class SoapLoggerExtension : SoapExtension
{
    private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
    private Stream oldStream;
    private Stream newStream;

    public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
    {
        return null;
    }

    public override object GetInitializer(Type serviceType)
    {
        return null;
    }

    public override void Initialize(object initializer)
    {

    }

    public override System.IO.Stream ChainStream(System.IO.Stream stream)
    {
        oldStream = stream;
        newStream = new MemoryStream();
        return newStream;
    }

    public override void ProcessMessage(SoapMessage message)
    {

        switch (message.Stage)
        {
            case SoapMessageStage.BeforeSerialize:
                break;
            case SoapMessageStage.AfterSerialize:
                Log(message, "AfterSerialize");
                    CopyStream(newStream, oldStream);
                    newStream.Position = 0;
                break;
                case SoapMessageStage.BeforeDeserialize:
                    CopyStream(oldStream, newStream);
                    Log(message, "BeforeDeserialize");
                break;
            case SoapMessageStage.AfterDeserialize:
                break;
        }
    }

    public void Log(SoapMessage message, string stage)
    {

        newStream.Position = 0;
        string contents = (message is SoapServerMessage) ? "SoapRequest " : "SoapResponse ";
        contents += stage + ";";

        StreamReader reader = new StreamReader(newStream);

        contents += reader.ReadToEnd();

        newStream.Position = 0;

        log.Debug(contents);
    }

    void ReturnStream()
    {
        CopyAndReverse(newStream, oldStream);
    }

    void ReceiveStream()
    {
        CopyAndReverse(newStream, oldStream);
    }

    public void ReverseIncomingStream()
    {
        ReverseStream(newStream);
    }

    public void ReverseOutgoingStream()
    {
        ReverseStream(newStream);
    }

    public void ReverseStream(Stream stream)
    {
        TextReader tr = new StreamReader(stream);
        string str = tr.ReadToEnd();
        char[] data = str.ToCharArray();
        Array.Reverse(data);
        string strReversed = new string(data);

        TextWriter tw = new StreamWriter(stream);

        TextWriter tw = new StreamWriter(to);

        string str = tr.ReadToEnd();
        char[] data = str.ToCharArray();
        Array.Reverse(data);
        string strReversed = new string(data);
        tw.Write(strReversed);
        tw.Flush();
    }

    private void CopyStream(Stream fromStream, Stream toStream)
    {
        try
        {
            StreamReader sr = new StreamReader(fromStream);
            StreamWriter sw = new StreamWriter(toStream);
            sw.WriteLine(sr.ReadToEnd());
            sw.Flush();
        }
        catch (Exception ex)
        {
            string message = String.Format("CopyStream failed because: {0}", ex.Message);
            log.Error(message, ex);

[AttributeUsage(AttributeTargets.Method)]
public class SoapLoggerExtensionAttribute : SoapExtensionAttribute
{
    private int priority = 1; 

    public override int Priority
    {
        get { return priority; }

    }

    public override System.Type ExtensionType
    {
        get { return typeof (SoapLoggerExtension); }

}

You then add the following section to your web.config where YourNamespace and YourAssembly point to the class and assembly of your SoapExtension:

    <add type="YourNamespace.SoapLoggerExtension, YourAssembly" 
       priority="1" group="0" />

</webServices>

Exchange Access Token for Mobile Number and Country Code (Server Side OR Client Side)

You can get the mobile number with your access_token with this API https://graph.accountkit.com/v1.1/me/?access_token=xxxxxxxxxxxx. Maybe, once you have the mobile number and the id, you can work with it to verify the user with your server & database.

xxxxxxxxxx above is the Access Token

Example Response :

{
   "id": "61940819992708",
   "phone": {
      "number": "+91XX82923912",
      "country_prefix": "91",
      "national_number": "XX82923912"
   }
}

Exchange Auth Code for Access Token (Server Side)

If you have an Auth Code instead, you can first get the Access Token with this API - https://graph.accountkit.com/v1.1/access_token?grant_type=authorization_code&code=xxxxxxxxxx&access_token=AA|yyyyyyyyyy|zzzzzzzzzz

xxxxxxxxxx, yyyyyyyyyy and zzzzzzzzzz above are the Auth Code, App ID and App Secret respectively.

Example Response

{
   "id": "619XX819992708",
   "access_token": "EMAWdcsi711meGS2qQpNk4XBTwUBIDtqYAKoZBbBZAEZCZAXyWVbqvKUyKgDZBniZBFwKVyoVGHXnquCcikBqc9ROF2qAxLRrqBYAvXknwND3dhHU0iLZCRwBNHNlyQZD",
   "token_refresh_interval_sec": XX92000
}

Note - This is preferred on the server-side since the API requires the APP Secret which is not meant to be shared for security reasons.

Good Luck.

As already mentioned, array_unique() could be used, but only when dealing with simple data. The objects are not so simple to handle.

When php tries to merge the arrays, it tries to compare the values of the array members. If a member is an object, it cannot get its value and uses the spl hash instead. Read more about spl_object_hash here.

Simply told if you have two objects, instances of the very same class and if one of them is not a reference to the other one - you will end up having two objects, no matter the value of their properties.

To be sure that you don't have any duplicates within the merged array, Imho you should handle the case on your own.

Also if you are going to merge multidimensional arrays, consider using array_merge_recursive() over array_merge().

Besides the solution of using an additional list and calling addAll to insert the new items after the iteration (as e.g. the solution by user Nat), you can also use concurrent collections like the CopyOnWriteArrayList.

The "snapshot" style iterator method uses a reference to the state of the array at the point that the iterator was created. This array never changes during the lifetime of the iterator, so interference is impossible and the iterator is guaranteed not to throw ConcurrentModificationException.

With this special collection (usually used for concurrent access) it is possible to manipulate the underlying list while iterating over it. However, the iterator will not reflect the changes.

Is this better than the other solution? Probably not, I don't know the overhead introduced by the Copy-On-Write approach.

In current versions of Mac Catalina

1. go to packages tab --> Settings View ---> Install Packages/Themes ---> +Install button --> add "platformio-ide-terminal"

2. control ~ to get the terminal

Another formula option is to use REPLACE function to replace the first n characters with nothing, e.g. if n = 4

=REPLACE(A1,1,4,"")

The reason for the issue is wrong or typo in the Bucket/Key name. Do check if the bucket or key name you are providing does exists.

df.apply(pd.value_counts).fillna(0)

value_counts - Returns object containing counts of unique values

apply - count frequency in every column. If you set axis=1, you get frequency in every row

fillna(0) - make output more fancy. Changed NaN to 0

This works:

any(c.isalpha() for c in 'string')

Seen a lot of the answers, but the correct one is to provide the full options for the header function call as per the php manual

void header ( string $string [, bool $replace = true [, int $http_response_code ]] )

If you invoke with

header('HTTP/1.0 403 Forbidden', true, 403);

the normal behavior of HTTP 403 as configured with Apache or any other server would follow.

In my case, I was able to find the problem by temporarily catching the exception, descending into causes as needed (based on how deep the IllegalAnnotationException was), and calling getErrors() on it.

    try {
        // in my case, this was what gave me an exception
        endpoint.publish("/MyWebServicePort");
    // I got a WebServiceException caused by another exception, which was caused by the IllegalAnnotationsException
    } catch (WebServiceException e) {
        // Incidentally, I need to call getCause().getCause() on it, and cast to IllegalAnnotationsException before calling getErrors()
        System.err.println(((com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException)e.getCause().getCause()).getErrors());
    }

After some investigation about file dates I solved the same issue (which is a randomly recurrent trouble on my Kepler) by simply deleting the following file in my local workspace: .metadata.plugins\org.eclipse.jdt.core\variablesAndContainers.dat

with negligible impact on the workspace restoring.

I hope it can help someone else...

To start, I would suggest to test whether there is a problem between your application and its dependencies using dependency walker

JWT (JSON Web Tokens)- It is just a token format. JWT tokens are JSON encoded data structures contains information about issuer, subject (claims), expiration time etc. It is signed for tamper proof and authenticity and it can be encrypted to protect the token information using symmetric or asymmetric approach. JWT is simpler than SAML 1.1/2.0 and supported by all devices and it is more powerful than SWT(Simple Web Token).

OAuth2 - OAuth2 solve a problem that user wants to access the data using client software like browse based web apps, native mobile apps or desktop apps. OAuth2 is just for authorization, client software can be authorized to access the resources on-behalf of end user using access token.

OpenID Connect - OpenID Connect builds on top of OAuth2 and add authentication. OpenID Connect add some constraint to OAuth2 like UserInfo Endpoint, ID Token, discovery and dynamic registration of OpenID Connect providers and session management. JWT is the mandatory format for the token.

CSRF protection - You don't need implement the CSRF protection if you do not store token in the browser's cookie.

By default, div elements are displayed as block elements, so they have 100% width, making centering them meaningless. As suggested by Arief, you must specify a width and you can then use auto when specifying margin in order to center a div.

Alternatively, you could also force display: inline, but then you'd have something that pretty much behaves like a span instead of a div, so that doesn't make a lot of sense.

After mounting on drive, use shutil.unpack_archive. It works with almost all archive formats (e.g., “zip”, “tar”, “gztar”, “bztar”, “xztar”) and it's simple:

import shutil
shutil.unpack_archive("filename", "path_to_extract")

Manually:

int strlen(string s)
{
    int len = 0;

    while (s[len])
        len++;

    return len;
}

1.

JSON.stringify(o);

Item: {"a":"1", "b":"2"}

2.

var o = {a:1, b:2};
var b=[]; Object.keys(o).forEach(function(k){b.push(k+":"+o[k]);});
b="{"+b.join(', ')+"}";
console.log('Item: ' + b);

Item: {a:1, b:2}

This will work for the MacOS for Firefox and Chrome:

// opens the default browser tab with the first webpage
driver.get("the url 1");
thread.sleep(2000);

// opens the second tab
driver.findElement(By.cssSelector("Body")).sendKeys(Keys.COMMAND + "t");
driver.get("the url 2");
Thread.sleep(2000);

// comes back to the first tab
driver.findElement(By.cssSelector("Body")).sendKeys(Keys.COMMAND, Keys.SHIFT, "{");

UPDATE test SET a = CONCAT(a, "more text")

In the Manifest, you can set the screenOrientation to landscape. It would look something like this in the XML:

<activity android:name="MyActivity"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation|screenSize">
...
</activity>

Where MyActivity is the one you want to stay in landscape.

The android:configChanges=... line prevents onResume(), onPause() from being called when the screen is rotated. Without this line, the rotation will stay as you requested but the calls will still be made.

Note: keyboardHidden and orientation are required for < Android 3.2 (API level 13), and all three options are required 3.2 or above, not just orientation.

you can use simple code its work for transaction

Fragment newFragment = new MainCategoryFragment();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_frame_NavButtom, newFragment);
ft.commit(); 

contentCompressionResistancePriority – The view with the lowest value gets truncated when there is not enough space to fit everything’s intrinsicContentSize

contentHuggingPriority – The view with the lowest value gets expanded beyond its intrinsicContentSize when there is leftover space to fill

This command works for me:

./mysql -u root -p

(PS: I'm working on mac through terminal)

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

If you want an ANSI SQL-92 version:

select view_definition from information_schema.views where table_name = 'view_name';

Package name is your android app id .

String appId = BuildConfig.APPLICATION_ID

Or

https://play.google.com/store/apps/details?id=com.whatsapp

App Id = com.whatsapp

I had a problem like this whereby I had specified the width of my Window, but had the height set to Auto. The child DockPanel had it's VerticalAlignment set to Top and the Window had it's VerticalContentAlignment set to Top, yet the Window would still be much taller than the contents.

Using Snoop, I discovered that the ContentPresenter within the Window (part of the Window, not something I had put there) has it's VerticalAlignment set to Stretch and can't be changed without retemplating the entire Window!

After a lot of frustration, I discovered the SizeToContent property - you can use this to specify whether you want the Window to size vertically, horizontally or both, according to the size of the contents - everything is sizing nicely now, I just can't believe it took me so long to find that property!

If you were using AppCompatActivity and have gone down the path of not using it, because you wanted to not get the automatic ActionBar that it provides, because you want to separate out the Toolbar, because of your Material Design needs and CoordinatorLayout or AppBarLayout, then, consider this:

You can still use the AppCompatActivity, you don't need to stop using it just so that you can use a <android.support.v7.widget.Toolbar> in your xml. Just turn off the action bar style as follows:

First, derive a style from one of the NoActionBar themes that you like in your styles.xml, I used Theme.AppCompat.Light.NoActionBar like so:

<style name="SuperCoolAppBarActivity" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/primary</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/primary_dark</item>
    ...
    ...
</style>

In your App's manifest, choose the child style theme you just defined, like so:

    <activity
        android:name=".activity.YourSuperCoolActivity"
        android:label="@string/super_cool"
        android:theme="@style/SuperCoolAppBarActivity">
    </activity>

In your Activity Xml, if the toolbar is defined like so:

...
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        />
...

Then, and this is the important part, you set the support Action bar to the AppCompatActivity that you're extending, so that the toolbar in your xml, becomes the action bar. I feel that this is a better way, because you can simply do the many things that ActionBar allows, like menus, automatic activity title, item selection handling, etc. without resorting to adding custom click handlers, etc.

In your Activity's onCreate override, do the following:

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_super_cool);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

    setSupportActionBar(toolbar);
    //Your toolbar is now an action bar and you can use it like you always do, for example:
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
} 

Let video muted first to ensure autoplay in ios, then unmute it if you want.

<video autoplay loop muted playsinline>
  <source src="video.mp4?123" type="video/mp4">
</video>

<script type="text/javascript">
$(function () {
  if (!navigator.userAgent.match(/(iPod|iPhone|iPad)/)) {
    $("video").prop('muted', false);
  }
});
</script>

If you want to get new line characters used in current OS like \r\n for Windows, you can get them by

• System.getProperty("line.separator");
• since Java7 System.lineSeparator()
• or as mentioned by Stewart generate them via String.format("%n");

You can also use PrintStream and its println method which will add OS dependent line separator at the end of your string automatically

PrintStream fileStream = new PrintStream(new File("file.txt"));
fileStream.println("your data");
//         ^^^^^^^ will add OS line separator after data 

(BTW System.out is also instance of PrintStream).

$.getJSON(url,function(json){
if ( json.length == 0 ) 
{
console.log("NO !")
}
});

<div style="display:table;width:100%"  >
<div style="display:table-cell;width:49%" id="div1">
content
</div>

<!-- space between divs - display table-cell -->
<div style="display:table-cell;width:1%" id="separated"></div>
<!-- //space between divs - display table-cell -->

<div style="display:table-cell;width:50%" id="div2">
content
</div>
</div>

Angular CLI 1.7 introduced ng update.

ng update

A new Angular CLI command to help simplify keeping your projects up to date with the latest versions. Packages can define logic which will be applied to your projects to ensure usage of latest features as well as making changes to reduce or eliminate the impact related to breaking changes.

Configuration information for ng update can be found here

1.7 to 6 update

CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.

npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1

UPDATED 30/04/2017:

1.0 Update

You should now follow the Angular CLI migration guide

UPDATED 04/03/2017:

RC Update

You should follow the Angular CLI RC migration guide

UPDATED 20/02/2017:

Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update

The pull request here states the following:

BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.

The angular-cli CHANGELOG.md states the following:

BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.

UPDATED 17/02/2017:

Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -

Global package:

npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init

ORIGINAL ANSWER

You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.

Here they are:

Updating angular-cli

To update angular-cli to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

Local project package:

rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init

Running ng init will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).

Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.

I also faced a similar issue. The reason was that I had the changes done in the .aspx page but not the designer page and hence I got the mentioned error. When the reference was created in the designer page I was able to build the solution.

My issue was I was instatiating the player completely from start but I used an iframe instead of a wrapper div.

A reliable way to construct a File instance on a resource retrieved from a jar is it to copy the resource as a stream into a temporary File (the temp file will be deleted when the JVM exits):

public static File getResourceAsFile(String resourcePath) {
    try {
        InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
        if (in == null) {
            return null;
        }

        File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
        tempFile.deleteOnExit();

        try (FileOutputStream out = new FileOutputStream(tempFile)) {
            //copy stream
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = in.read(buffer)) != -1) {
                out.write(buffer, 0, bytesRead);
            }
        }
        return tempFile;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

You can't do it with pure html/javascript. This is because you have a seperate connection to the webserver to retrieve a separate file (the image) and a normal webserver will serve the file with content headers set so that the browser reading the content type will decide that the type can be handled internally.

The way to force the browser not to handle the file internally is to change the headers (content-disposition prefereably, or content-type) so the browser will not try to handle the file internally. You can either do this by writing a script on the webserver that dynamically sets the headers (i.e. download.php) or by configuring the webserver to return different headers for the file you want to download. You can do this on a per-directory basis on the webserver, which would allow you to get away without writing any php or javascript - simply have all your download images in that one location.

Not doing the correct level of normalization. You want to make sure that data is not duplicated, and that you are splitting data into different as needed. You also need to make sure you are not following normalization too far as that will hurt performance.

This doesn't work for me, I want to to like jquery slideUp / slideDown function, I tried this code, but it only move the content wich stay at the same place after animation end, the view should have a 0dp height at start of slideDown and the view height (with wrap_content) after the end of the animation.

If you get this error in CollectionView try to create CustomCell file and Custom xib also.

add this code in ViewDidLoad() at mainVC.

    let nib = UINib(nibName: "CustomnibName", bundle: nil)
    self.collectionView.register(nib, forCellWithReuseIdentifier: "cell")

DELETE FROM blob
WHERE NOT EXISTS (
    SELECT *
    FROM files
    WHERE id=blob.id
)

For UIViewController just load your view again -

func rightButtonAction() {
        if isEditProfile {
           print("Submit Clicked, Call Update profile API")
            isEditProfile = false
            self.viewWillAppear(true)
        } else {
            print("Edit Clicked, Call Edit profile API")
            isEditProfile = true
            self.viewWillAppear(true)
        }
    }

I am loading my view controller on profile edit and view profile. According to the Bool value isEditProfile updating the view in viewWillAppear method.

If you're not religious about keeping your HTML valid then I can see use cases where having the same ID on multiple elements may be useful.

One example is testing. Often we identify elements to test against by finding all elements with a particular class. However, if we find ourselves adding classes purely for testing purposes, then I would contend that that's wrong. Classes are for styling, not identification.

If IDs are for identification, why must it be that only one element can have a particular identifier? Particularly in today's frontend world, with reusable components, if we don't want to use classes for identification, then we need to use IDs. But, if we use multiples of a component, we'll have multiple elements with the same ID.

I'm saying that's OK. If that's anathema to you, that's fine, I understand your view. Let's agree to disagree and move on.

If you want a solution that actually finds all IDs of the same name though, then it's this:

function getElementsById(id) {
    const elementsWithId = []
    const allElements = document.getElementsByTagName('*')
    for(let key in allElements) {
        if(allElements.hasOwnProperty(key)) {
            const element = allElements[key]
            if(element.id === id) {
                elementsWithId.push(element)
            }        
        }
    }
    return elementsWithId
}

EDIT, ES6 FTW:

function getElementsById(id) {
    return [...document.getElementsByTagName('*')].filter(element => element.id === id)
}

In a Firebird database the AFTER myOtherColumn does not work but you can try re-positioning the column using:

ALTER TABLE name ALTER column POSITION new_position

I guess it may work in other cases as well.

You can download the complete folder under Clone or Download options (Git URL or Download Zip)

1. There is a button of Download Zip

2. By using command you can download the complete folder on your machine but for that you need git on your machine. You can find the Git url uner

   git clone https://github.com/url

<td style = "display:none" >
<p> Content display none </p>
</td>

or

<td style="visibility:hidden"> Your content is hidden </td>

Notice that: 2 those ways are differnce. You should try it to check the result.

In my case, I installed the Windows SDK 10586 via Visual Studio 2015 -> Modify, then the following paths are installed.

C:\Program Files (x86)\Windows Kits\10\bin\arm64\rc.exe

C:\Program Files (x86)\Windows Kits\10\bin\x64\rc.exe

C:\Program Files (x86)\Windows Kits\10\bin\x86\rc.exe

In SQL Server 2008,2012,2014 you can insert multiple rows using a single SQL INSERT statement.

 INSERT INTO TableName ( Column1, Column2 ) VALUES
    ( Value1, Value2 ), ( Value1, Value2 )

Another way

INSERT INTO TableName (Column1, Column2 )
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2

I like using delay() to get this done, here's an example:

jQuery(element).animate({ backgroundColor: "#FCFCD8" },1).delay(1000).animate({ backgroundColor: "#EFEAEA" }, 1500);

This can be called by a function, with "element" being the element class/name/etc. The element will instantly appear with the #FCFCD8 background, hold for a second, then fade into #EFEAEA.

This is similar to https://superuser.com/questions/477628/export-all-regular-expression-matches-in-textpad-or-notepad-as-a-list.

I hope you are trying to extract :
"Performance"
"Maintenance"
"System Stability"

Here is the way - Step 1/3: Open Search->Find->Replace Tab , select Regular Expression Radio button. Enter in Find what : (\"[a-zA-Z0-9\s]+\") and in Replace with : \n\1 and click Replace All buttton.

Step 2/3: After first step your keywords will be in next lines.(as shown in next image). Now go to Mark tab and enter the same regex expression in Find what: Field. Put check mark on Bookmark Line. Then Click Mark All.

Step 3/3 : Goto Search -> Bookmarks -> Remove unmarked lines.

So you have the final result as below

The default strategy for @Column(name="TestName") will be test_name, this is correct behavior!

If you have a column named TestName in your database you should change Column annotation to @Column(name="testname").

This works because database does not care if you name your column TestName or testname (column names are case insensitive!!).

But beware, the same does not apply for database name and table names, that are case sensitive on Unix systems but case in sensitive on Windows systems (the fact that probably kept a lot of people awake at night, working on windows but deploying on linux :))

The single star * unpacks the sequence/collection into positional arguments, so you can do this:

def sum(a, b):
    return a + b

values = (1, 2)

s = sum(*values)

This will unpack the tuple so that it actually executes as:

s = sum(1, 2)

The double star ** does the same, only using a dictionary and thus named arguments:

values = { 'a': 1, 'b': 2 }
s = sum(**values)

You can also combine:

def sum(a, b, c, d):
    return a + b + c + d

values1 = (1, 2)
values2 = { 'c': 10, 'd': 15 }
s = sum(*values1, **values2)

will execute as:

s = sum(1, 2, c=10, d=15)

Also see section 4.7.4 - Unpacking Argument Lists of the Python documentation.

Additionally you can define functions to take *x and **y arguments, this allows a function to accept any number of positional and/or named arguments that aren't specifically named in the declaration.

Example:

def sum(*values):
    s = 0
    for v in values:
        s = s + v
    return s

s = sum(1, 2, 3, 4, 5)

or with **:

def get_a(**values):
    return values['a']

s = get_a(a=1, b=2)      # returns 1

this can allow you to specify a large number of optional parameters without having to declare them.

And again, you can combine:

def sum(*values, **options):
    s = 0
    for i in values:
        s = s + i
    if "neg" in options:
        if options["neg"]:
            s = -s
    return s

s = sum(1, 2, 3, 4, 5)            # returns 15
s = sum(1, 2, 3, 4, 5, neg=True)  # returns -15
s = sum(1, 2, 3, 4, 5, neg=False) # returns 15

Regarding 3rd definition:

var foo = function foo() { return 5; }

Heres an example which shows how to use possibility of recursive call:

a = function b(i) { 
  if (i>10) {
    return i;
  }
  else {
    return b(++i);
  }
}

console.log(a(5));  // outputs 11
console.log(a(10)); // outputs 11
console.log(a(11)); // outputs 11
console.log(a(15)); // outputs 15

Edit: more interesting example with closures:

a = function(c) {
 return function b(i){
  if (i>c) {
   return i;
  }
  return b(++i);
 }
}
d = a(5);
console.log(d(3)); // outputs 6
console.log(d(8)); // outputs 8

Semicolon should be at the end of the class definition rather than after the name:

class WordGame
{
};

Run this in SSMS, it shows how line breaks in the SQL itself become part of string values that span lines :

PRINT 'Line 1
Line 2
Line 3'
PRINT ''

PRINT 'How long is a blank line feed?'
PRINT LEN('
')
PRINT ''

PRINT 'What are the ASCII values?'
PRINT ASCII(SUBSTRING('
',1,1))
PRINT ASCII(SUBSTRING('
',2,1))

Result :
Line 1
Line 2
Line 3

How long is a blank line feed?
2

What are the ASCII values?
13
10

Or if you'd rather specify your string on one line (almost!) you could employ REPLACE() like this (optionally use CHAR(13)+CHAR(10) as the replacement) :

PRINT REPLACE('Line 1`Line 2`Line 3','`','
')

Place your pointer on the dock button and long click it (some seconds) or right & left mouse click depending on the browser version.

You could do this with an INSTEAD OF INSERT trigger on the table, that checks for the existance of the row and then updates/inserts depending on whether it exists already. There is an example of how to do this for SQL Server 2000+ on MSDN here:

CREATE TRIGGER IO_Trig_INS_Employee ON Employee
INSTEAD OF INSERT
AS
BEGIN
SET NOCOUNT ON
-- Check for duplicate Person. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT P.SSN
      FROM Person P, inserted I
      WHERE P.SSN = I.SSN))
   INSERT INTO Person
      SELECT SSN,Name,Address,Birthdate
      FROM inserted
ELSE
-- Log attempt to insert duplicate Person row in PersonDuplicates table.
   INSERT INTO PersonDuplicates
      SELECT SSN,Name,Address,Birthdate,SUSER_SNAME(),GETDATE()
      FROM inserted
-- Check for duplicate Employee. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT E.SSN
      FROM EmployeeTable E, inserted
      WHERE E.SSN = inserted.SSN))
   INSERT INTO EmployeeTable
      SELECT EmployeeID,SSN, Department, Salary
      FROM inserted
ELSE
--If duplicate, change to UPDATE so that there will not
--be a duplicate key violation error.
   UPDATE EmployeeTable
      SET EmployeeID = I.EmployeeID,
          Department = I.Department,
          Salary = I.Salary
   FROM EmployeeTable E, inserted I
   WHERE E.SSN = I.SSN
END

Try this, you can create an extension method like this:

    public static string ContentToString(this HttpContent httpContent)
    {
        var readAsStringAsync = httpContent.ReadAsStringAsync();
        return readAsStringAsync.Result;
    }

and then, simple call the extension method:

txtBlock.Text = response.Content.ContentToString();

I hope this help you ;-)

First, I wouldn't use document.body. Instead add an empty container:

index.html:

<html>
    <head></head>
    <body>
        <div id="app"></div>
    </body>
</html>

Then opt to only render your <App /> element:

main.js:

var App = require('./App.js');
ReactDOM.render(<App />, document.getElementById('app'));

Within App.js you can import your other components and ignore your DOM render code completely:

App.js:

var SampleComponent = require('./SampleComponent.js');

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component!</h1>
                <SampleComponent name="SomeName" />
            </div>
        );
    }
});

SampleComponent.js:

var SampleComponent = React.createClass({
    render: function() {
        return (
            <div>
                <h1>Sample Component!</h1>
            </div>
        );
    }
});

Then you can programmatically interact with any number of components by importing them into the necessary component files using require.

This is really similar to another question. How should I load files into my Java application?

How should I load my files into my Java Application?

You do not want to load your files in by:

C:\your\project\file.txt

this is bad!

You should use getResourceAsStream.

InputStream inputStream = YourClass.class.getResourceAsStream(“file.txt”);

And also you should use File.separator; which is the system-dependent name-separator character, represented as a string for convenience.

To return just the names of the registered submodules, you can use this command:

grep path .gitmodules | sed 's/.*= //'

Think of it as git submodule --list which doesn't exist.

In VueJS 3 with createApp() you can use app.config.globalProperties

Like this:

const app = createApp(App);

app.config.globalProperties.foo = 'bar';

app.use(store).use(router).mount('#app');

and call your variable like this:

app.component('child-component', {
  mounted() {
    console.log(this.foo) // 'bar'
  }
})

IsNullOrWhiteSpace is a convenience method that is similar to the following code, except that it offers superior performance:

return String.IsNullOrEmpty(value) || value.Trim().Length == 0;

White-space characters are defined by the Unicode standard. The IsNullOrWhiteSpace method interprets any character that returns a value of true when it is passed to the Char.IsWhiteSpace method as a white-space character.

If you program in Lua, you are out of luck here. Lua is THE one programming language that just happens to be notoriously infamous because its authors never implemented "the" split function in the standard library, and instead wrote 16 screenfulls of explanations and lame excuses as to why they didn't and wouldn't, interspersed with numerous half-working examples that are virtually guaranteed to work for almost everyone but break in your corner case. This is just Lua state of the art, and everyone who programs in Lua simply ends up clenching their teeth and iterating over characters. There are lots of solutions in existence that are sometimes better, but exactly zero solutions that are reliably better.

It hides the intention of the code.

It's two single tilde operators, so it does a bitwise complement (bitwise not) twice. The operations take out each other, so the only remaining effect is the conversion that is done before the first operator is applied, i.e. converting the value to an integer number.

Some use it as a faster alternative to Math.floor, but the speed difference is not that dramatic, and in most cases it's just micro optimisation. Unless you have a piece of code that really needs to be optimised, you should use code that descibes what it does instead of code that uses a side effect of a non-operation.

Update 2011-08:

With optimisation of the JavaScript engine in browsers, the performance for operators and functions change. With current browsers, using ~~ instead of Math.floor is somewhat faster in some browsers, and not faster at all in some browsers. If you really need that extra bit of performance, you would need to write different optimised code for each browser.

See: tilde vs floor

Why use GROUP BY at all?

SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players

This will do it for you:

function inArray(needle, haystack) {
    var length = haystack.length;
    for(var i = 0; i < length; i++) {
        if(haystack[i] == needle)
            return true;
    }
    return false;
}

I found it in Stack Overflow question JavaScript equivalent of PHP's in_array().

Do you want to make the label (except for the text) transparent? Windows Forms (I assume WinForms - is this true) doesn't really support transparency. The easiest way, sometimes, is Label's Backcolor to Transparent.

label1.BackColor = System.Drawing.Color.Transparent;

You will run into problems though, as WinForms really doesn't properly support transparency. Otherwise, see here:

Setting the parent of a usercontrol prevents it from being transparent

Good luck!

If x is constant, the following parameter expansion performs substring extraction:

b=${a:12:5}

where 12 is the offset (zero-based) and 5 is the length

If the underscores around the digits are the only ones in the input, you can strip off the prefix and suffix (respectively) in two steps:

tmp=${a#*_}   # remove prefix ending in "_"
b=${tmp%_*}   # remove suffix starting with "_"

If there are other underscores, it's probably feasible anyway, albeit more tricky. If anyone knows how to perform both expansions in a single expression, I'd like to know too.

Both solutions presented are pure bash, with no process spawning involved, hence very fast.

echo `date +%s`/86400 | bc

new Date(Date.now() + (-1*new Date().getTimezoneOffset()*60000)).toISOString()

SELECT col1, col2, IF( action = 2 AND state = 0, 1, 0 ) AS state from tbl1;

OR

SELECT col1, col2, (case when (action = 2 and state = 0) then 1 else 0 end) as state from tbl1;

both results will same....

Here is a different solution, that also allows the replacement of a single group in multiple matches. It uses stacks to reverse the execution order, so the string operation can be safely executed.

private static void demo () {

    final String sourceString = "hello world!";

    final String regex = "(hello) (world)(!)";
    final Pattern pattern = Pattern.compile(regex);

    String result = replaceTextOfMatchGroup(sourceString, pattern, 2, world -> world.toUpperCase());
    System.out.println(result);  // output: hello WORLD!
}

public static String replaceTextOfMatchGroup(String sourceString, Pattern pattern, int groupToReplace, Function<String,String> replaceStrategy) {
    Stack<Integer> startPositions = new Stack<>();
    Stack<Integer> endPositions = new Stack<>();
    Matcher matcher = pattern.matcher(sourceString);

    while (matcher.find()) {
        startPositions.push(matcher.start(groupToReplace));
        endPositions.push(matcher.end(groupToReplace));
    }
    StringBuilder sb = new StringBuilder(sourceString);
    while (! startPositions.isEmpty()) {
        int start = startPositions.pop();
        int end = endPositions.pop();
        if (start >= 0 && end >= 0) {
            sb.replace(start, end, replaceStrategy.apply(sourceString.substring(start, end)));
        }
    }
    return sb.toString();       
}

There's no problem. I would even remove the CreateNewOrUpdateExisting from the source and use map[key] = value directly in your code, because this this is much more readable, because developers would usually know what map[key] = value means.

Assuming you have a JSON hash hanging around somewhere, to automatically convert it into something like WarHog's version, wrap your JSON hash contents in %q{hsh} tags.

This seems to automatically add all the necessary escaped text like in WarHog's answer.

Something along the lines of this?

<asp:TextBox id="txtUsername" runat="server" />

<asp:RegularExpressionValidator
    id="RegularExpressionValidator1"
    runat="server"
    ErrorMessage="Field not valid!"
    ControlToValidate="txtUsername"
    ValidationExpression="[0-9a-zA-Z]{6,}" />

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

Bootstrap Version 3.x

As always, read Bootstrap's great documentation:

3.x Docs: https://getbootstrap.com/docs/3.3/css/#grid-nesting

Make sure the parent level row is inside of a .container element. Whenever you'd like to nest rows, just open up a new .row inside of your column.

Here's a simple layout to work from:

<div class="container">
    <div class="row">
        <div class="col-xs-6">
            <div class="big-box">image</div>
        </div>
        <div class="col-xs-6">
            <div class="row">
                <div class="col-xs-6"><div class="mini-box">1</div></div>
                <div class="col-xs-6"><div class="mini-box">2</div></div>
                <div class="col-xs-6"><div class="mini-box">3</div></div>
                <div class="col-xs-6"><div class="mini-box">4</div></div>

Which will look like this (with a little bit of added styling):

Array.isArray(obj), does not give very helpful results. I've created a prototype method of Object, that seems to correctly determine whether and object is an array or not.

The only edge case that I know of where it fails is when item in the array is set to undefined.

Object.prototype.isArrayLike = function()
{
    var length = this.length || Object.keys(this).length;
    if (length === 0 || this.constructor.name === "String")
        return false;
    for (i = 0; i < length; i++)
    {
        if (typeof this[i] === "undefined")
            return false;
    }
    return true;
};

var arr = ['aaa', 'bbb', 'ccc', 'ddd'];
var arr1 = {"0":'aaa', "1":'bbb', 2:'ccc', 3:'ddd'};
var arr2 = {"0":'aaa', "a":'bbb', 2:'ccc', 3:'ddd'};
var arr3 = "qwerty";
var arr4 = [];
var arr5 = {0:'aaa', 1:'bbb', 2:'ccc', 3:'ddd'};

console.log("arrayLike:" + arr.isArrayLike());
console.log("Array.isArray(arr):" + Array.isArray(arr));
// arrayLike: true
// Array.isArray(arr): true
console.log("arrayLike1:" + arr1.isArrayLike());
console.log("Array.isArray(arr1):" + Array.isArray(arr1));
// arrayLike1: true
// Array.isArray(arr1): false
console.log("arrayLike2:" + arr2.isArrayLike());
console.log("Array.isArray(arr2):" + Array.isArray(arr2));
// arrayLike2: false
// Array.isArray(arr2): false
console.log("arrayLike3:" + arr3.isArrayLike());
console.log("Array.isArray(arr3):" + Array.isArray(arr3));
// arrayLike3: false
// Array.isArray(arr3): false
console.log("arrayLike4:" + arr4.isArrayLike());
console.log("Array.isArray(arr4):" + Array.isArray(arr4));
// arrayLike4: false
// Array.isArray(arr4): true
console.log("arrayLike5:" + arr5.isArrayLike());
console.log("Array.isArray(arr5):" + Array.isArray(arr5));
// arrayLike5: false
// Array.isArray(arr5): true

It can be used to use features which will appear in newer versions while having an older release of Python.

For example

>>> from __future__ import print_function

will allow you to use print as a function:

>>> print('# of entries', len(dictionary), file=sys.stderr)

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

You can fill your data table like the below code.I am also fetching the connections at runtime using a predefined XML file that has all the connection.

  public static DataTable Execute_Query(string connection, string query)
    {
        Logger.Info("Execute Query has been called for connection " + connection);
        connection = "Data Source=" + Connections.run_singlevalue(connection, "server") + ";Initial Catalog=" + Connections.run_singlevalue(connection, "database") + ";User ID=" + Connections.run_singlevalue(connection, "username") + ";Password=" + Connections.run_singlevalue(connection, "password") + ";Connection Timeout=30;";
        DataTable dt = new DataTable();
        try
        {
            using (SqlConnection con = new SqlConnection(connection))
            {
                using (SqlCommand cmd = new SqlCommand(query, con))
                {
                    con.Open();
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        da.SelectCommand.CommandTimeout = 1800;
                        da.Fill(dt);
                    }
                    con.Close();
                }
            }
            Logger.Info("Execute Query success");
            return dt;
        }
        catch (Exception ex)
        {
            Console.Write(ex.Message);
            return null;
        }
    }   

I learned this shortcut from working at the network deployment position. It helped me so much, I figured I will share this secret with everyone. So far, I have not able to find an easier way online that I know of.

For example a network 192.115.103.64 /27, what is the range?

just remember that subnet mask is 0, 128, 192, 224, 240, 248, 252, 254, 255

255.255.255.255 11111111.11111111.11111111.11111111 /32

255.255.255.254 11111111.11111111.11111111.11111110 /31

255.255.255.252 11111111.11111111.11111111.11111100 /30

255.255.255.248 11111111.11111111.11111111.11111000 /29

255.255.255.240 11111111.11111111.11111111.11110000 /28

255.255.255.224 11111111.11111111.11111111.11100000 /27

255.255.255.192 11111111.11111111.11111111.11000000 /26

255.255.255.128 11111111.11111111.11111111.10000000 /25

255.255.255.0 11111111.11111111.11111111.00000000 /24

from /27 we know that (11111111.11111111.11111111.11100000). Counting from the left, it is the third number from the last octet, which equal 255.255.255.224 subnet mask. (Don't count 0, 0 is /24) so 128, 192, 224..etc

Here where the math comes in:

use the subnet mask - subnet mask of the previous listed subnet mask in this case 224-192=32

We know 192.115.103.64 is the network: 64 + 32 = 96 (the next network for /27)

which means we have .0 .32. 64. 96. 128. 160. 192. 224. (Can't use 256 because it is .255)

Here is the range 64 -- 96.

network is 64.

first host is 65.(first network +1)

Last host is 94. (broadcast -1)

broadcast is 95. (last network -1)

In System.Web.Mvc.Html ( in System.Web.Mvc.dll ) the begin form is defined like:- Details

BeginForm ( this HtmlHelper htmlHelper, string actionName, string
controllerName, object routeValues, FormMethod method, object htmlAttributes)

Means you should use like this :

Html.BeginForm( string actionName, string controllerName,object routeValues, FormMethod method, object htmlAttributes)

So, it worked in MVC 4

@using (Html.BeginForm(null, null, new { @id = string.Empty }, FormMethod.Post,
    new { @id = "signupform" }))
{
    <input id="TRAINER_LIST" name="TRAINER_LIST" type="hidden" value="">
    <input type="submit" value="Create" id="btnSubmit" />
}

Another easy way to do it without using if/else condition (works for both positive and negative numbers):

int n = 8;
List<String> messages = Arrays.asList("even", "odd");

System.out.println(messages.get(Math.abs(n%2)));

For an Odd no., the expression will return '1' as remainder, giving

messages.get(1) = 'odd' and hence printing 'odd'

else, 'even' is printed when the expression comes up with result '0'

Sticky session means that when a request comes into a site from a client all further requests go to the same server initial client request accessed. I believe that session affinity is a synonym for sticky session.

Based on @danijels's answer, dynamically create a class in VB.NET:

Imports System.Reflection
Imports System.Reflection.Emit

Public Class ObjectBuilder

Public Property myType As Object
Public Property myObject As Object

Public Sub New(fields As List(Of Field))
    myType = CompileResultType(fields)
    myObject = Activator.CreateInstance(myType)
End Sub

Public Shared Function CompileResultType(fields As List(Of Field)) As Type
    Dim tb As TypeBuilder = GetTypeBuilder()
    Dim constructor As ConstructorBuilder = tb.DefineDefaultConstructor(MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.RTSpecialName)

    For Each field In fields
        CreateProperty(tb, field.Name, field.Type)
    Next

    Dim objectType As Type = tb.CreateType()
    Return objectType
End Function

Private Shared Function GetTypeBuilder() As TypeBuilder
    Dim typeSignature = "MyDynamicType"
    Dim an = New AssemblyName(typeSignature)
    Dim assemblyBuilder As AssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(an, AssemblyBuilderAccess.Run)
    Dim moduleBuilder As ModuleBuilder = assemblyBuilder.DefineDynamicModule("MainModule")
    Dim tb As TypeBuilder = moduleBuilder.DefineType(typeSignature, TypeAttributes.[Public] Or TypeAttributes.[Class] Or TypeAttributes.AutoClass Or TypeAttributes.AnsiClass Or TypeAttributes.BeforeFieldInit Or TypeAttributes.AutoLayout, Nothing)
    Return tb
End Function

Private Shared Sub CreateProperty(tb As TypeBuilder, propertyName As String, propertyType As Type)
    Dim fieldBuilder As FieldBuilder = tb.DefineField("_" & propertyName, propertyType, FieldAttributes.[Private])

    Dim propertyBuilder As PropertyBuilder = tb.DefineProperty(propertyName, PropertyAttributes.HasDefault, propertyType, Nothing)
    Dim getPropMthdBldr As MethodBuilder = tb.DefineMethod("get_" & propertyName, MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.HideBySig, propertyType, Type.EmptyTypes)
    Dim getIl As ILGenerator = getPropMthdBldr.GetILGenerator()

    getIl.Emit(OpCodes.Ldarg_0)
    getIl.Emit(OpCodes.Ldfld, fieldBuilder)
    getIl.Emit(OpCodes.Ret)

    Dim setPropMthdBldr As MethodBuilder = tb.DefineMethod("set_" & propertyName, MethodAttributes.[Public] Or MethodAttributes.SpecialName Or MethodAttributes.HideBySig, Nothing, {propertyType})

    Dim setIl As ILGenerator = setPropMthdBldr.GetILGenerator()
    Dim modifyProperty As Label = setIl.DefineLabel()
    Dim exitSet As Label = setIl.DefineLabel()

    setIl.MarkLabel(modifyProperty)

Can be as easy as:

var ms = new MemoryStream(imageData);
System.Drawing.Image image = Image.FromStream(ms);

image.Save("c:\\image.jpg");

Testing it out:

byte[] imageData;

// Create the byte array.
var originalImage = Image.FromFile(@"C:\original.jpg");
using (var ms = new MemoryStream())
{
    originalImage.Save(ms, ImageFormat.Jpeg);
    imageData = ms.ToArray();
}

// Convert back to image.
using (var ms = new MemoryStream(imageData))
{
    Image image = Image.FromStream(ms);
    image.Save(@"C:\newImage.jpg");
}

>>> text=u'abcd'
>>> str(text)
'abcd'

If the string only contains ascii characters.

if you lost a "!" in your code ,like this code below, you'll also get this error.

import UIKit

class MemeDetailViewController : UIViewController {

    @IBOutlet weak var memeImage: UIImageView!

    var meme:Meme! // lost"!"

    override func viewWillAppear(animated: Bool) {

        super.viewWillAppear(animated)
        self.memeImage!.image = meme.memedImage
    }

    override func viewDidDisappear(animated: Bool) {
        super.viewDidDisappear(animated)
    }

}

SequenceEqual can be faster. Namely in the case where almost all of the time, both arrays have indeed the same length and are not the same object.

It's still not the same functionality as the OP's function, as it won't silently compare null values.

You don't say what system you're using, but as you already have some answers that may or may not work for Windows, I'll answer for POSIX systems.

In POSIX, keyboard input comes through something called a terminal interface, which by default buffers lines of input until Return/Enter is hit, so as to deal properly with backspace. You can change that with the tcsetattr call:

#include <termios.h>

struct termios info;
tcgetattr(0, &info);          /* get current terminal attirbutes; 0 is the file descriptor for stdin */
info.c_lflag &= ~ICANON;      /* disable canonical mode */
info.c_cc[VMIN] = 1;          /* wait until at least one keystroke available */
info.c_cc[VTIME] = 0;         /* no timeout */
tcsetattr(0, TCSANOW, &info); /* set immediately */

Now when you read from stdin (with getchar(), or any other way), it will return characters immediately, without waiting for a Return/Enter. In addition, backspace will no longer 'work' -- instead of erasing the last character, you'll read an actual backspace character in the input.

Also, you'll want to make sure to restore canonical mode before your program exits, or the non-canonical handling may cause odd effects with your shell or whoever invoked your program.

override is a C++11 keyword which means that a method is an "override" from a method from a base class. Consider this example:

   class Foo
   {
   public:
        virtual void func1();
   }

   class Bar : public Foo
   {
   public:
        void func1() override;
   }

If B::func1() signature doesn't equal A::func1() signature a compilation error will be generated because B::func1() does not override A::func1(), it will define a new method called func1() instead.

Your problem is that you are relying on the browser to resize your images. Browsers have notoriously poor image scaling algorithms, which will cause the ugly pixelization.

You should resize your images in a graphics program first before you use them on the webpage.

Also, you have a spelling mistake: it should say moz-crisp-edges; however, that won't help you in your case (because that resizing algorithm won't give you a high quality resize: https://developer.mozilla.org/En/CSS/Image-rendering)

It can be treated as defensive programming approach from the compiler - the variables must be assigned before it can be used.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

In my case, I was looking for a solution that allows one of the navbar items to be right aligned. In order to do this, you must add style="width:100%;" to the <ul class="navbar-nav"> and then add the ml-auto class to your navbar item.

Example from the guide:

\newcommand{\example}[2][YYY]{Mandatory arg: #2;
                                 Optional arg: #1.}

This defines \example to be a command with two arguments, 
referred to as #1 and #2 in the {<definition>}--nothing new so far. 
But by adding a second optional argument to this \newcommand 
(the [YYY]) the first argument (#1) of the newly defined 
command \example is made optional with its default value being YYY.

Thus the usage of \example is either:

   \example{BBB}
which prints:
Mandatory arg: BBB; Optional arg: YYY.
or:
   \example[XXX]{AAA}
which prints:
Mandatory arg: AAA; Optional arg: XXX.

Splaysort is an obscure sorting method based on splay trees, a type of adaptive binary tree. Splaysort is good not only for partially sorted data, but also partially reverse-sorted data, or indeed any data that has any kind of pre-existing order. It is O(nlogn) in the general case, and O(n) in the case where the data is sorted in some way (forward, reverse, organ-pipe, etc.).

Its great advantage over insertion sort is that it doesn't revert to O(n^2) behaviour when the data isn't sorted at all, so you don't need to be absolutely sure that the data is partially sorted before using it.

Its disadvantage is the extra space overhead of the splay tree structure it needs, as well as the time required to build and destroy the splay tree. But depending on the size of data and amount of pre-sortedness that you expect, the overhead may be worth it for the increase in speed.

A paper on splaysort was published in Software--Practice & Experience.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {

            }
        }
        return result;

    public class ItemInfoNode {

        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

I tried to return string from controller but why control returning to error block not in success of ajax

var sownum="aa";
$.ajax({
    type : "POST",
    contentType : 'application/json; charset=utf-8',
    dataType : "JSON",
    url : 'updateSowDetails.html?sownum=' + sownum,
    success : function() {
        alert("Wrong username");
    },
    error : function(request, status, error) {

        var val = request.responseText;
        alert("error"+val);
    }
});

I have created this function for iOS following the answer given by chmike

+ (NSArray *)intersectionPointsOfCircleWithCenter:(CGPoint)center withRadius:(float)radius toLinePoint1:(CGPoint)p1 andLinePoint2:(CGPoint)p2
{
    NSMutableArray *intersectionPoints = [NSMutableArray array];

    float Ax = p1.x;
    float Ay = p1.y;
    float Bx = p2.x;
    float By = p2.y;
    float Cx = center.x;
    float Cy = center.y;
    float R = radius;


    // compute the euclidean distance between A and B
    float LAB = sqrt( pow(Bx-Ax, 2)+pow(By-Ay, 2) );

    // compute the direction vector D from A to B
    float Dx = (Bx-Ax)/LAB;
    float Dy = (By-Ay)/LAB;

    // Now the line equation is x = Dx*t + Ax, y = Dy*t + Ay with 0 <= t <= 1.

    // compute the value t of the closest point to the circle center (Cx, Cy)
    float t = Dx*(Cx-Ax) + Dy*(Cy-Ay);

    // This is the projection of C on the line from A to B.

        float dt = sqrt( pow(R, 2) - pow(LEC,2) );

        // compute first intersection point
        float Fx = (t-dt)*Dx + Ax;
        float Fy = (t-dt)*Dy + Ay;

        // compute second intersection point
        float Gx = (t+dt)*Dx + Ax;
        float Gy = (t+dt)*Dy + Ay;

        [intersectionPoints addObject:[NSValue valueWithCGPoint:CGPointMake(Fx, Fy)]];

I am using mysql-5.7.12-osx10.11-x86_64.dmg in Mac OSX

The installation process automatically sets up a temporary password for root user. You should save the password. The password can not be recovered.

Follow the instruction

1. Go to cd /usr/local/mysql/bin/
2. Enter the temporary password (which would look something like, "tsO07JF1=>3")
3. You should get mysql> prompt.
4. Run, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('{YOUR_PASSWORD}'); If you wish to set your password: "root" then the command would be, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');
5. Run ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
6. Run exit
7. Run ./mysql -u root -p
8. Type your password. In my case I would type, "root" (without quote)
9. That's all.

For convenience, you should add "/usr/local/mysql/bin" to your PATH

Now from anywhere you can type ./mysql -u root -p and then type the password and you will get mysql> prompt.

Hope it helps.

There's a headers parameter in the config object you pass to $http for per-call headers:

$http({method: 'GET', url: 'www.google.com/someapi', headers: {
    'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

Or with the shortcut method:

$http.get('www.google.com/someapi', {
    headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

The list of the valid parameters is available in the $http service documentation.

Here is step-by-step instruction for Tomcat configuration in IntellijIdea:

1) Create IntellijIdea project via WebApplication template. Idea should be Ultimate version, not Community edition

2) Go to Run-Edit configutaion and set up Tomcat location folder, so Idea will know about your tomcat server

3) Go to Deployment tab and select Artifact. Apply

4) In src folder put your servlet (you can try my example for testing purpose)

5) Go to web.xml file and link your's servlet like this

6) In web folder put your's .jsp files (for example hey.jsp)

7) Now you can start you app via IntellijIdea. Run(Shift+F10) and enjoy your app in browser:

- to jsp files: http://localhost:8080/hey.jsp (or index.jsp by default)

- to servlets via virtual link you set in web.xml : http://localhost:8080/st

http://www.w3schools.com/cssref/css3_pr_animation-keyframes.asp

it is actually a browser issue... use -webkit- for chrome

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

Simple! The folder named .. is the parent folder, so you can make the path to the file you need as such

var foobar = require('../config/dev/foobar.json');

If you needed to go up two levels, you would write ../../ etc

Some more details about this in this SO answer and it's comments

From the Metaprogramming Ruby book,

The require() method is quite similar to load(), but it’s meant for a different purpose. You use load() to execute code, and you use require() to import libraries.

I had the same problem, changing my gmail password fixed the issue, and also don't forget to enable less secure app on on your gmail account

Note: This approach modifies your package.json on the fly, use it if you have no alternative.

I had to pass command line arguments to my scripts which were something like:

"scripts": {
    "start": "npm run build && npm run watch",
    "watch": "concurrently  \"npm run watch-ts\" \"npm run watch-node\"",
    ...
}

So, this means I start my app with npm run start.

Now if I want to pass some arguments, I would start with maybe:

npm run start -- --config=someConfig

What this does is: npm run build && npm run watch -- --config=someConfig. Problem with this is, it always appends the arguments to the end of the script. This means all the chained scripts don't get these arguments(Args maybe or may not be required by all, but that's a different story.). Further when the linked scripts are called then those scripts won't get the passed arguments. i.e. The watch script won't get the passed arguments.

The production usage of my app is as an .exe, so passing the arguments in the exe works fine but if want to do this during development, it gets problamatic.

I couldn't find any proper way to achieve this, so this is what I have tried.

I have created a javascript file: start-script.js at the parent level of the application, I have a "default.package.json" and instead of maintaining "package.json", I maintain "default.package.json". The purpose of start-script.json is to read default.package.json, extract the scripts and look for npm run scriptname then append the passed arguments to these scripts. After this, it will create a new package.json and copy the data from default.package.json with modified scripts and then call npm run start.

const fs = require('fs');
const { spawn } = require('child_process');

// open default.package.json
const defaultPackage = fs.readFileSync('./default.package.json');
try {
    const packageOb = JSON.parse(defaultPackage);
    // loop over the scripts present in this object, edit them with flags
    if ('scripts' in packageOb && process.argv.length > 2) {

        const passedFlags = ` -- ${process.argv.slice(2).join(' ')}`;
        // assuming the script names have words, : or -, modify the regex if required.
        const regexPattern = /(npm run [\w:-]*)/g;
        const scriptsWithFlags = Object.entries(packageOb.scripts).reduce((acc, [key, value]) => {
            const patternMatches = value.match(regexPattern);
            // loop over all the matched strings and attach the desired flags.
            if (patternMatches) {
                for (let eachMatchedPattern of patternMatches) {
                    const startIndex = value.indexOf(eachMatchedPattern);
                    const endIndex = startIndex + eachMatchedPattern.length;
                    // save the string which doen't fall in this matched pattern range.
                    value = value.slice(0, startIndex) + eachMatchedPattern + passedFlags + value.slice(endIndex);
                }
            }
            acc[key] = value;
            return acc;
        }, {});
        packageOb.scripts = scriptsWithFlags;
    }

    const modifiedJSON = JSON.stringify(packageOb, null, 4);
    fs.writeFileSync('./package.json', modifiedJSON);

    // now run your npm start script
    let cmd = 'npm';
    // check if this works in your OS
    if (process.platform === 'win32') {
        cmd = 'npm.cmd';    // https://github.com/nodejs/node/issues/3675
    }
    spawn(cmd, ['run', 'start'], { stdio: 'inherit' });

} catch(e) {
    console.log('Error while parsing default.package.json', e);
}

Now, instead of doing npm run start, I do node start-script.js --c=somethis --r=somethingElse

The initial run looks fine, but haven't tested thoroughly. Use it, if you like for you app development.

If its SQL Server you can do it on the column properties within design view

Try this?:

ALTER TABLE dbo.TableName 
  ADD CONSTRAINT DF_TableName_ColumnName
    DEFAULT '01/01/2000' FOR ColumnName

You will get output from column value 9 to 26 as you have mentioned OFFSET as 8

This esc behavior is IE only by the way. Instead of using jQuery use good old javascript for creating the element and it works.

var element = document.createElement('input');
element.type = 'text';
element.value = 100;
document.getElementsByTagName('body')[0].appendChild(element);

http://jsfiddle.net/gGrf9/

If you want to extend this functionality to other browsers then I would use jQuery's data object to store the default. Then set it when user presses escape.

//store default value for all elements on page. set new default on blur
$('input').each( function() {
    $(this).data('default', $(this).val());
    $(this).blur( function() { $(this).data('default', $(this).val()); });
});

$('input').keyup( function(e) {
    if (e.keyCode == 27) { $(this).val($(this).data('default')); }
});

while || true is preferred one, but you can also do

var=$(echo $(exit 1)) # it shouldn't fail

I know this is a bit old, but in case another beginner is going through this, I'll share some code that covers a bit more of the basic operations, here is another example that also includes the option to cancel the process and also report to the user the status of the process. I'm going to add on top of the code given by Alex Aza in the solution above

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted;  //Tell the user how the process went
    backgroundWorker1.WorkerReportsProgress = true;
    backgroundWorker1.WorkerSupportsCancellation = true; //Allow for the process to be cancelled
}

//Start Process
private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

//Cancel Process
private void button2_Click(object sender, EventArgs e)
{
    //Check if background worker is doing anything and send a cancellation if it is
    if (backgroundWorker1.IsBusy)
    {
        backgroundWorker1.CancelAsync();
    }

}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);

        //Check if there is a request to cancel the process
        if (backgroundWorker1.CancellationPending)
        {
            e.Cancel = true;
            backgroundWorker1.ReportProgress(0);
            return;
        }
    }
    //If the process exits the loop, ensure that progress is set to 100%
    //Remember in the loop we set i < 100 so in theory the process will complete at 99%
    backgroundWorker1.ReportProgress(100);
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled)
    {
         lblStatus.Text = "Process was cancelled";
    }
    else if (e.Error != null)
    {
         lblStatus.Text = "There was an error running the process. The thread aborted";
    }
    else
    {
       lblStatus.Text = "Process was completed";
    }
}

IOS 10 Update:

I had a problem with building the fatlib with iphoneos10.0 because the regular expression in the script only expects 9.x and lower and returns 0.0 for ios 10.0

to fix this just replace

SDK_VERSION=$(echo ${SDK_NAME} | grep -o '.\{3\}$')

with

SDK_VERSION=$(echo ${SDK_NAME} | grep -o '[\\.0-9]\{3,4\}$')

What kind of field is this? The IN operator cannot be used with a single field, but is meant to be used in subqueries or with predefined lists:

-- subquery
SELECT a FROM x WHERE x.b NOT IN (SELECT b FROM y);
-- predefined list
SELECT a FROM x WHERE x.b NOT IN (1, 2, 3, 6);

If you are searching a string, go for the LIKE operator (but this will be slow):

-- Finds all rows where a does not contain "text"
SELECT * FROM x WHERE x.a NOT LIKE '%text%';

If you restrict it so that the string you are searching for has to start with the given string, it can use indices (if there is an index on that field) and be reasonably fast:

-- Finds all rows where a does not start with "text"
SELECT * FROM x WHERE x.a NOT LIKE 'text%';

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

Solution for naughty LOLLIPOP

**

hello i had rly big problem with having that darker than was my color... so this is solution to avoid that shadow behind status bar from solution with TranslucentStatus...

so in all of your java activity you need this:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    }

and at your styles.xml you need to set background color (this color will be your status bar color):

<style name="AppCompat" parent="Theme.AppCompat">
    <item name="android:colorBackground">@color/YOUR_STATUS_BAR_COLOR</item>
</style>

and at all your layouts you need to add layout which will be your background:

<LinearLayout
    android:background="@color/YOUR_BACKGROUND_COLOR"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    />

of course if you would like use @color/just name... you need to set that at colors.xml:

<color name="YOUR_STATUS_BAR_COLOR">#cf031c</color>
<color name="YOUR_BACKGROUND_COLOR">#383838</color>

here is whole process how we did done that: Whats the right approach to create or change color of a status bar?

Try this:

function createcodes() {

    $('.authors-list tr').each(function () {
        //processing this row
        //how to process each cell(table td) where there is checkbox
        $(this).find('td input:checked').each(function () {

             // it is checked, your code here...
        });
    });
}

If the number of the set would be within 32, 64 or a machine native primitive size, then you can do it with a simple bit manipulation.

template<typename T>
void combo(const T& c, int k)
{
    int n = c.size();
    int combo = (1 << k) - 1;       // k bit sets
    while (combo < 1<<n) {

        pretty_print(c, combo);

        int x = combo & -combo;
        int y = combo + x;
        int z = (combo & ~y);
        combo = z / x;
        combo >>= 1;
        combo |= y;
    }
}

this example calls pretty_print() function by the dictionary order.

For example. You want to have 6C3 and assuming the current 'combo' is 010110. Obviously the next combo MUST be 011001. 011001 is : 010000 | 001000 | 000001

010000 : deleted continuously 1s of LSB side. 001000 : set 1 on the next of continuously 1s of LSB side. 000001 : shifted continuously 1s of LSB to the right and remove LSB bit.

int x = combo & -combo;

this obtains the lowest 1.

int y = combo + x;

this eliminates continuously 1s of LSB side and set 1 on the next of it (in the above case, 010000 | 001000)

int z = (combo & ~y)

this gives you the continuously 1s of LSB side (000110).

combo = z / x;
combo >> =1;

this is for 'shifted continuously 1s of LSB to the right and remove LSB bit'.

So the final job is to OR y to the above.

combo |= y;

Some simple concrete example :

#include <bits/stdc++.h>

using namespace std;

template<typename T>
void pretty_print(const T& c, int combo)
{
    int n = c.size();
    for (int i = 0; i < n; ++i) {
        if ((combo >> i) & 1)
            cout << c[i] << ' ';
    }
    cout << endl;
}

template<typename T>
void combo(const T& c, int k)
{
    int n = c.size();
    int combo = (1 << k) - 1;       // k bit sets
    while (combo < 1<<n) {

        pretty_print(c, combo);

        int x = combo & -combo;

In the above example they going to display all user and particular id details now I want to use both id and name,

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

now I want to use both id and name

localhost:8093/plejson/shop/user/11/raju <-----------------like this it means we can use any one in this please help me out.....

You can easily do it with below code:

Note: The second argument in RegExp is 'g' which is the global search flag. The global search flag makes the RegExp search for a pattern throughout the string, creating an array of all occurrences it can find matching the given pattern. Below code only works if the time is in HH:MM:SS format i.e. 24 hour time format.

var regex = new RegExp(':', 'g'),
    timeStr1 = '5:50:55',
    timeStr2 = '6:17:05';
if(parseInt(timeStr1.replace(regex, ''), 10) < parseInt(timeStr2.replace(regex, ''), 10)){
  console.log('timeStr1 is smaller then timeStr2');
} else {
  console.log('timeStr2 is smaller then timeStr1');
}

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

You can find the last date of any month by this code:

var now = DateTime.Now;
var startOfMonth = new DateTime(now.Year, now.Month, 1);
var DaysInMonth = DateTime.DaysInMonth(now.Year, now.Month);
var lastDay = new DateTime(now.Year, now.Month, DaysInMonth);

To add a new cookie, use HttpServletResponse.addCookie(Cookie). The Cookie is pretty much a key value pair taking a name and value as strings on construction.

Sample to execute an SQL string within the stored procedure:

(I'm using this to compare the number of entries on each table as first check for a regression test, within a cursor loop)

select @SqlQuery1 = N'select @CountResult1 = (select isnull(count(*),0) from ' + @DatabaseFirst+'.dbo.'+@ObjectName + ')'

execute sp_executesql    @SqlQuery1 , N'@CountResult1 int OUTPUT',     @CountResult1 = @CountResult1 output;

Simply replace image/jpeg with application/octet-stream. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.

A simple JavaScript solution would be:

//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element, 

Another method is to use a blob: URI:

var img = document.images[0];
img.onclick = function() {
    // atob to base64_decode the data-URI
    var image_data = atob(img.src.split(',')[1]);
    // Use typed arrays to convert the binary data to a Blob
    var arraybuffer = new ArrayBuffer(image_data.length);
    var view = new Uint8Array(arraybuffer);
    for (var i=0; i<image_data.length; i++) {
        view[i] = image_data.charCodeAt(i) & 0xff;
    }
    try {
        // This is the recommended method:
        var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
    } catch (e) {
        // The BlobBuilder API has been deprecated in favour of Blob, but older
        // browsers don't know about the Blob constructor
        // IE10 also supports BlobBuilder, but since the `Blob` constructor
        //  also works, there's no need to add `MSBlobBuilder`.
        var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
        bb.append(arraybuffer);
        var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
    }

    // Use the URL object to create a temporary URL
    var url = (window.webkitURL || window.URL).createObjectURL(blob);
    location.href = url; // <-- Download!
};

If you're working in a large multi-module project, with several different application.properties files, then try adding your value to the parent project's property file.

If you are unsure which is your parent project, check your project's pom.xml file, for a <parent> tag.

This solved the issue for me.

If you want to do this from outside the script:

Python 2

from modulefinder import ModuleFinder
finder = ModuleFinder()
finder.run_script("myscript.py")
for name, mod in finder.modules.iteritems():
    print name

Python 3

from modulefinder import ModuleFinder
finder = ModuleFinder()
finder.run_script("myscript.py")
for name, mod in finder.modules.items():
    print(name)

This will print all modules loaded by myscript.py.

First, implement the MyData.equals(Object o) and MyData.hashCode() methods. Once you implemented the equals method, you can iterate over the lists as follows:

if(ListA == null && ListB == null)
    return false;
if(ListA == null && ListB != null)
    return true;
if(ListA != null && ListB == null)
    return true;
int max = ListA.size() > ListB.size() ? ListA.size() : ListB.size();
for(int i = 0; i < max; i++) {
    myData1 = ListA.get(i);
    myData2 = ListB.get(i);
    if(!myData1.equals(myData2)) {
        return true;
    }
}
return false;

Had the same problem. found some videos on Youtube. So here is an even simpler suggestion. This is all the code you need:

#include <QDebug>

int main(int argc, char *argv[])  
{
   qDebug() <<"Hello World"<< endl;
   return 0;
}

The above code comes from Qt5 Tutorial: Building a simple Console application by

Dominique Thiebaut

I was also facing the same error. The reason for this is that there is no smtp server on your environment. For creating a fake smtp server I used this fake-smtp.jar file for creating a virtual server and listening to all the requests. If you are facing the same error, I recommend you to use this jar and run it after extracting and then try to run your application.

Download latest version of fake smtp

Security Notice: Basing the cookie off an MD5 hash of deterministic data is a bad idea; it's better to use a random token derived from a CSPRNG. See ircmaxell's answer to this question for a more secure approach.

Usually I do something like this:

1. User logs in with 'keep me logged in'
2. Create session
3. Create a cookie called SOMETHING containing: md5(salt+username+ip+salt) and a cookie called somethingElse containing id
4. Store cookie in database
5. User does stuff and leaves ----
6. User returns, check for somethingElse cookie, if it exists, get the old hash from the database for that user, check of the contents of cookie SOMETHING match with the hash from the database, which should also match with a newly calculated hash (for the ip) thus: cookieHash==databaseHash==md5(salt+username+ip+salt), if they do, goto 2, if they don't goto 1

Off course you can use different cookie names etc. also you can change the content of the cookie a bit, just make sure it isn't to easily created. You can for example also create a user_salt when the user is created and also put that in the cookie.

Also you could use sha1 instead of md5 (or pretty much any algorithm)

@bogatron has it right, you can use where, it's worth noting that you can do this natively in pandas:

df1 = df.where(pd.notnull(df), None)

Note: this changes the dtype of all columns to object.

Example:

In [1]: df = pd.DataFrame([1, np.nan])

In [2]: df
Out[2]: 
    0
0   1
1 NaN

In [3]: df1 = df.where(pd.notnull(df), None)

In [4]: df1
Out[4]: 
      0
0     1
1  None

Note: what you cannot do recast the DataFrames dtype to allow all datatypes types, using astype, and then the DataFrame fillna method:

df1 = df.astype(object).replace(np.nan, 'None')

Unfortunately neither this, nor using replace, works with None see this (closed) issue.

As an aside, it's worth noting that for most use cases you don't need to replace NaN with None, see this question about the difference between NaN and None in pandas.

However, in this specific case it seems you do (at least at the time of this answer).

vitaminwater's answer is working for me.

If your textview's text is bouncing up and down during edit, after setting [textView setScrollEnabled:NO];, set Size Inspector > Scroll View > Content Insets > Never.

Hope it helps.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload
[default] Attempting graceful shutdown of VM...

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

In case if you need a matrix with predefined numbers you can use the following code:

def matrix(rows, cols, start=0):
    return [[c + start + r * cols for c in range(cols)] for r in range(rows)]


assert matrix(2, 3, 1) == [[1, 2, 3], [4, 5, 6]]

To convert the data to a MySQL database, you can use the Bullzip Access to MySQL program. It's free and easy to use.

http://www.bullzip.com/products/a2m/info.php

create keystore file through command line

keytool -genkey -alias key_file_name.keystore -keyalg RSA -validity 1000000000000000 -keystore key_file_name.keystore

export apk through Eclipse, right click on Android project Android Tools > Export Signed Application Package, then give keystore location & password.

this will crate signed apk at the same time apk will be zipaligned. And installable.

If you go through command line for all, some times you may face "Application not installed" error. (Application not installed error can happen not only, when using command line. It can be some other reasons as well)

You are creating a set via set(...) call, and set needs hashable items. You can't have set of lists. Because list's arent hashable.

[[(a,b) for a in range(3)] for b in range(3)] is a list. It's not a hashable type. The __hash__ you saw in dir(...) isn't a method, it's just None.

A list comprehension returns a list, you don't need to explicitly use list there, just use:

>>> [[(a,b) for a in range(3)] for b in range(3)]
[[(0, 0), (1, 0), (2, 0)], [(0, 1), (1, 1), (2, 1)], [(0, 2), (1, 2), (2, 2)]]

Try those:

>>> a = {1, 2, 3}
>>> b= [1, 2, 3]
>>> type(a)
<class 'set'>
>>> type(b)
<class 'list'>
>>> {1, 2, []}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
>>> print([].__hash__)
None
>>> [[],[],[]] #list of lists
[[], [], []]
>>> {[], [], []} #set of lists
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

ubar jar is also known as fat jar i.e. jar with dependencies.
There are three common methods for constructing an uber jar:

1. Unshaded: Unpack all JAR files, then repack them into a single JAR. Works with Java's default class loader. Tools maven-assembly-plugin
2. Shaded: Same as unshaded, but rename (i.e., "shade") all packages of all dependencies. Works with Java's default class loader. Avoids some (not all) dependency version clashes. Tools maven-shade-plugin
3. JAR of JARs: The final JAR file contains the other JAR files embedded within. Avoids dependency version clashes. All resource files are preserved. Tools: Eclipse JAR File Exporter

        return !m[n] * ~arr.indexOf(n, m[n] = ++i);
    });
}

Use Ruby way

Here is a nice explanation of update operation with some examples. Although it is Postgres site, but the SQL queries are valid for the other DBs, too. The following examples are intuitive to understand.

-- Update contact names in an accounts table to match the currently assigned salesmen:

UPDATE accounts SET (contact_first_name, contact_last_name) =
    (SELECT first_name, last_name FROM salesmen
     WHERE salesmen.id = accounts.sales_id);

-- A similar result could be accomplished with a join:

UPDATE accounts SET contact_first_name = first_name,
                    contact_last_name = last_name
  FROM salesmen WHERE salesmen.id = accounts.sales_id;

However, the second query may give unexpected results if salesmen.id is not a unique key, whereas the first query is guaranteed to raise an error if there are multiple id matches. Also, if there is no match for a particular accounts.sales_id entry, the first query will set the corresponding name fields to NULL, whereas the second query will not update that row at all.

Hence for the given example, the most reliable query is like the following.

UPDATE tempDataView SET (marks) =
    (SELECT marks FROM tempData
     WHERE tempDataView.Name = tempData.Name);

Robert Rossney has a good solution. Here's an alternative solution I've used in the past that separates out the "Overlay" from the rest of the content. This solution takes advantage of the attached property Panel.ZIndex to place the "Overlay" on top of everything else. You can either set the Visibility of the "Overlay" in code or use a DataTrigger.

<Grid x:Name="LayoutRoot">

 <Grid x:Name="Overlay" Panel.ZIndex="1000" Visibility="Collapsed">
    <Grid.Background>
      <SolidColorBrush Color="Black" Opacity=".5"/>
    </Grid.Background>

    <!-- Add controls as needed -->
  </Grid>

  <!-- Use whatever layout you need -->
  <ContentControl x:Name="MainContent" />

</Grid>

I was working on a program that required me to check if the user correctly answered how many digits were in a number, so i had to develop a way to check the amount of digits in an integer. It ended up being a relatively easy thing to solve.

double check=0, exponent=1000;

while(check<=1)
{
    check=number/pow(10, exponent);
    exponent--;
}

exponent=exponent+2;
cout<<exponent<<endl;

This ended up being my answer which currently works with numbers with less than 10^1000 digits (can be changed by changing the value of exponent).

P.S. I know this answer is ten years late but I got here on 2020 so other people might use it.

If you click on the title CSS (SCSS) in CodePen (don't change the pre-processor with the gear) it will switch to the compiled CSS view.

For simply checking against Object or Array without additional function call (speed).

isArray()

isArray = function(a) {
    return (!!a) && (a.constructor === Array);
};
console.log(isArray(        )); // false
console.log(isArray(    null)); // false
console.log(isArray(    true)); // false
console.log(isArray(       1)); // false
console.log(isArray(   'str')); // false
console.log(isArray(      {})); // false
console.log(isArray(new Date)); // false
console.log(isArray(      [])); // true

isObject()

isObject = function(a) {
    return (!!a) && (a.constructor === Object);
};
console.log(isObject(        )); // false
console.log(isObject(    null)); // false
console.log(isObject(    true)); // false
console.log(isObject(       1)); // false
console.log(isObject(   'str')); // false
console.log(isObject(      [])); // false
console.log(isObject(new Date)); // false
console.log(isObject(      {})); // true

        method_output = method(self, *method_args, **method_kwargs)

    return _impl

class Foo:
    @wrapper
    def bar(self, word):
        return word

f = Foo()
result = f.bar("kitty")
print(result)

Which will print:

kitty!

For some reason, I couldn't find a general example of how to do this with Queue anywhere (even Python's doc examples don't spawn multiple processes), so here's what I got working after like 10 tries:

def add_helper(queue, arg1, arg2): # the func called in child processes
    ret = arg1 + arg2
    queue.put(ret)

def multi_add(): # spawns child processes
    q = Queue()
    processes = []
    rets = []
    for _ in range(0, 100):
        p = Process(target=add_helper, args=(q, 1, 2))
        processes.append(p)
        p.start()
    for p in processes:
        ret = q.get() # will block
        rets.append(ret)
    for p in processes:
        p.join()
    return rets

Queue is a blocking, thread-safe queue that you can use to store the return values from the child processes. So you have to pass the queue to each process. Something less obvious here is that you have to get() from the queue before you join the Processes or else the queue fills up and blocks everything.

Update for those who are object-oriented (tested in Python 3.4):

from multiprocessing import Process, Queue

class Multiprocessor():

    def __init__(self):
        self.processes = []
        self.queue = Queue()

I was able to get past this by using the Array keyword instead of empty brackets:

const enhancers: Array<any> = [];

Use:

if (typeof devToolsExtension === 'function') {
  enhancers.push(devToolsExtension())
}

Press Ctrl + Shift + P to open the Command Palette.

In an attempt to spot a change somewhere in a particular column (here in "W", i.e. "23"), I modified Peter Alberts' answer to:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Target.Column = 23 Then Exit Sub
    Application.EnableEvents = False             'to prevent endless loop
    On Error GoTo Finalize                       'to re-enable the events
    MsgBox "You changed a cell in column W, row " & Target.Row
    MsgBox "You changed it to: " & Target.Value
Finalize:
    Application.EnableEvents = True
End Sub

You can hit the key q (for quit) and it should take you to the prompt.

If you're using JQuery you can do:

$('#elementid').click();

If you are working with Storyboards, you can click on the controller, switch to the properties tab, and set the title text there.

My issue was that I had overlapping names in the file paths for different types, like this:

<cache-path
    name="cached_files"
    path="." />
<external-cache-path
    name="cached_files"
    path="." />

After I changed the names ("cached_files") to be unique, I got rid of the error. My guess is that those paths are stored in some HashMap or something which does not allow duplicates.

BlobBuilder is obsolete, use Blob constructor instead:

URL.createObjectURL(new Blob([/*whatever content*/] , {type:'text/plain'}));

This returns a blob URL which you can then use in an anchor's href. You can also modify an anchor's download attribute to manipulate the file name:

<a href="/*assign url here*/" id="link" download="whatever.txt">download me</a>

Fiddled. If I recall correctly, there are arbitrary restrictions on trusted non-user initiated downloads; thus we'll stick with a link clicking which is seen as sufficiently user-initiated :)

Update: it's actually pretty trivial to save current document's html! Whenever our interactive link is clicked, we'll update its href with a relevant blob. After executing the click-bound event, that's the download URL that will be navigated to!

$('#link').on('click', function(e){
  this.href = URL.createObjectURL(
    new Blob([document.documentElement.outerHTML] , {type:'text/html'})
  );
});

Fiddled again.

The best way is using the transparent color code

android:background="#00000000"

use the color code #00000000 for making any thing transparent

//BEWARE
//This works ONLY if the server returns 401 first
//The client DOES NOT send credentials on first request
//ONLY after a 401
client.Credentials = new NetworkCredential(userName, passWord); //doesnt work

//So use THIS instead to send credentials RIGHT AWAY
string credentials = Convert.ToBase64String(
    Encoding.ASCII.GetBytes(userName + ":" + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(
    "Basic {0}", credentials);

close() is a webdriver command which closes the browser window which is currently in focus. Despite the familiar name for this method, WebDriver does not implement the AutoCloseable interface.

During the automation process, if there are more than one browser window opened, then the close() command will close only the current browser window which is having focus at that time. The remaining browser windows will not be closed. The following code can be used to close the current browser window:

quit() is a webdriver command which calls the driver.dispose method, which in turn closes all the browser windows and terminates the WebDriver session. If we do not use quit() at the end of program, the WebDriver session will not be closed properly and the files will not be cleared off memory. This may result in memory leak errors.

If the Automation process opens only a single browser window, the close() and quit() commands work in the same way. Both will differ in their functionality when there are more than one browser window opened during Automation.

For Above Ref : click here

Dispose Command Dispose() should call Quit(), and it appears it does. However, it also has the same problem in that any subsequent actions are blocked until PhantomJS is manually closed.

you need to decode the bytes of you want a string:

b = b'1234'
print(b.decode('utf-8'))  # '1234'

I believe this line in the web.config will set the max upload size:

<system.web>

        <httpRuntime maxRequestLength="600000"/>
</system.web>

See the documentation for the print function: print()

The content of end is printed after the thing you want to print. By default it contains a newline ("\n") but it can be changed to something else, like an empty string.

I've just had the same problem.

You only get the text twice in your result if you include a match group (in brackets) and the 'g' (global) modifier. The first item always is the first result, normally OK when using match(reg) on a short string, however when using a construct like:

while ((result = reg.exec(string)) !== null){
    console.log(result);
}

the results are a little different.

Try the following code:

var regEx = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
var result = sample_string.match(regEx);
console.log(JSON.stringify(result));
// ["1 cat","2 fish"]

var reg = new RegExp('[0-9]+ (cat|fish)','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null) {
    console.dir(JSON.stringify(result))
};
// '["1 cat","cat"]'
// '["2 fish","fish"]'

var reg = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null){
    console.dir(JSON.stringify(result))
};
// '["1 cat","1 cat","cat"]'
// '["2 fish","2 fish","fish"]'

The best answer is currently a comment which I can't upvote, so credit to @Mic.

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.
