I vote for:

await Promise.all([someCall(), anotherCall()]);

Be aware of the moment you call functions, it may cause unexpected result:

// Supposing anotherCall() will trigger a request to create a new User

if (callFirst) {
  await someCall();
} else {
  await Promise.all([someCall(), anotherCall()]); // --> create new User here
}

But following always triggers request to create new User

// Supposing anotherCall() will trigger a request to create a new User

const someResult = someCall();
const anotherResult = anotherCall(); // ->> This always creates new User

if (callFirst) {
  await someCall();
} else {
  const finalResult = [await someResult, await anotherResult]
}

Swift 4.1 introduces new -Osize optimization mode.

In Swift 4.1 the compiler now supports a new optimization mode which enables dedicated optimizations to reduce code size.

The Swift compiler comes with powerful optimizations. When compiling with -O the compiler tries to transform the code so that it executes with maximum performance. However, this improvement in runtime performance can sometimes come with a tradeoff of increased code size. With the new -Osize optimization mode the user has the choice to compile for minimal code size rather than for maximum speed.

To enable the size optimization mode on the command line, use -Osize instead of -O.

The simplest I've found is using background jobs in the shell:

for d in /main/files/*; do
    rsync -a "$d" remote:/main/files/ &
done

Beware it doesn't limit the amount of jobs! If you're network-bound this is not really a problem but if you're waiting for spinning rust this will be thrashing the disk.

You could add

while [ $(jobs | wc -l | xargs) -gt 10 ]; do sleep 1; done

inside the loop for a primitive form of job control.

Suspended. The session is waiting for an event, such as I/O, to complete.

After some additional searching (new search terms inspired by gbn's answer and u07ch's comment on KMike's answer) I found this, which completed successfully in 2 seconds:

ALTER DATABASE <dbname> SET OFFLINE WITH ROLLBACK IMMEDIATE

(Update)

When this still fails with the following error, you can fix it as inspired by this blog post:

ALTER DATABASE failed because a lock could not be placed on database 'dbname' Try again later.

you can run the following command to find out who is keeping a lock on your database:

EXEC sp_who2

And use whatever SPID you find in the following command:

KILL <SPID>

Then run the ALTER DATABASE command again. It should now work.

json = " { \"success\" : false, \"errors\": { \"text\" : \"??????!\" } }";            
return new MemoryStream(Encoding.UTF8.GetBytes(json));

If you want this to work in IE 8 and below, use

<!--[if lte IE 8]>

lte meaning "Less than or equal".

For more on conditional comments, see e.g. the quirksmode.org page.

In PostgreSQL, you can do:

SELECT  *
FROM    (
        VALUES
        (1, 2),
        (3, 4)
        ) AS q (col1, col2)

In other systems, just use UNION ALL:

SELECT  1 AS col1, 2 AS col2
-- FROM    dual
-- uncomment the line above if in Oracle
UNION ALL
SELECT  3 AS col1, 3 AS col2
-- FROM    dual
-- uncomment the line above if in Oracle

In Oracle, SQL Server and PostgreSQL, you also can generate recordsets of arbitrary number of rows (providable with an external variable):

SELECT  level
FROM    dual
CONNECT BY
        level <= :n

in Oracle,

WITH    q (l) AS
        (
        SELECT  1
        UNION ALL
        SELECT  l + 1
        FROM    q
        WHERE   l < @n
        )
SELECT  l
FROM    q
-- OPTION (MAXRECURSION 0)
-- uncomment line above if @n >= 100

in SQL Server,

SELECT  l
FROM    generate_series(1, $n) l

in PostgreSQL.

It is purely a string:

startInfo.Arguments = "-sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"

Of course, when arguments contain whitespaces you'll have to escape them using \" \", like:

"... -ss \"My MyAdHocTestCert.cer\""

See MSDN for this.

T-SQL doesn't support arrays that I'm aware of.

What's your table structure? You could probably design a query that does this instead:

select
month,
sum(sales)
from sales_table
group by month
order by month

.newLine() is the best if your system property line.separator is proper . and sometime you don't want to change the property runtime . So alternative solution is appending \n

Based on Abraham Mayowa Oluwasina answer provided above is the correct one. MacOS Catalina, .bash_profile is no longer apple's default shell and it won't persist your path variables instead use .zprofile instead.

In root directory,

touch .zprofile
open -e .zprofile

Add the following in file,

export ANDROID_HOME=/Users/<username>/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/platform-tools

Save and exit

To activate

source ~/. zprofile

echo $ANDROID_HOME

Example:

#pragma warning(suppress:0000)  // (suppress one error in the next line)

This pragma is valid for C++ starting with Visual Studio 2005.
https://msdn.microsoft.com/en-us/library/2c8f766e(v=vs.80).aspx

The pragma is NOT valid for C# through Visual Studio 2005 through Visual Studio 2015.
Error: "Expected disable or restore".
(I guess they never got around to implementing suppress ...)
https://msdn.microsoft.com/en-us/library/441722ys(v=vs.140).aspx

C# needs a different format. It would look like this (but not work):

#pragma warning suppress 0642  // (suppress one error in the next line)

Instead of suppress, you have to disable and enable:

if (condition)
#pragma warning disable 0642
    ;  // Empty statement HERE provokes Warning: "Possible mistaken empty statement" (CS0642)
#pragma warning restore 0642
else

That is SO ugly, I think it is smarter to just re-style it:

if (condition)
{
    // Do nothing (because blah blah blah).
}
else

There are many ways to do this, one is reject

noEmptyCities = cities.reject { |c| c.empty? }

You can also use reject!, which will modify cities in place. It will either return cities as its return value if it rejected something, or nil if no rejections are made. That can be a gotcha if you're not careful (thanks to ninja08 for pointing this out in the comments).

This is my second time encounter this problem. first time according the alphazero's recommendation it worked. but in the second time I set to 1.6 it don't work it just like 'CACHE' this error after clean and rebuild.

Try to switch off 'Build Automatically' as Rollin_s said -> error still here!

So I removed the problem project (already set to 1.6) from Package Explorer and import it again -> it start a rebuild and no error this time

Hope this help someone

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).

Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?

Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -

// Error.h
class Error {
public:
  static Error& NOT_FOUND;
  static Error& UNKNOWN;
  static Error& NONE; // singleton object that represents null

public:
  static vector<shared_ptr<Error>> _instances;
  static Error& NewInstance(const string& name, bool isNull = false);

private:
  bool _isNull;
  Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
  Error() {};
  Error(const Error& src) {};
  Error& operator=(const Error& src) {};

public:
  operator Error*() { return _isNull ? nullptr : this; }
};

// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
  shared_ptr<Error> pNewInst(new Error(name, isNull)).
  Error::_instances.push_back(pNewInst);
  return *pNewInst.get();
}

Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");

// Main.cpp
#include "Error.h"

Error& getError() {
  return Error::UNKNOWN;
}

// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
  return Error::NONE;
}

int main(void) {
  if(getError() != Error::NONE) {
    return EXIT_FAILURE;
  }

  // Edit: To see the overload of "Error*()" in Error.h actually working
  if(getErrorNone() != nullptr) {
    return EXIT_FAILURE;
  }
}

container class has 15px left & right padding, so if you want to remove this padding, use following, because row class has -15px left & right margin.

<div class="container">
  <div class="row">
     <img class='img-responsive' src="#" alt="" />
  </div>
</div>

Codepen: http://codepen.io/m-dehghani/pen/jqeKgv

cls

$exactadminfile = "C:\temp\files\admin" #First folder to check the file

$userfile = "C:\temp\files\user" #Second folder to check the file

$filenames=Get-Content "C:\temp\files\files-to-watch.txt" #Reading the names of the files to test the existance in one of the above locations

foreach ($filename in $filenames) {
  if (!(Test-Path $exactadminfile\$filename) -and !(Test-Path $userfile\$filename)) { #if the file is not there in either of the folder
    Write-Warning "$filename absent from both locations"
  } else {
    Write-Host " $filename  File is there in one or both Locations" #if file exists there at both locations or at least in one location
  }
}

Note that there is an unrelated issue in your code but that could bite you later: you should return res.json() or you will not catch any error occurring in JSON parsing or your own function processing data.

Back to your error: You cannot have a TypeError: failed to fetch with a successful request. You probably have another request (check your "network" panel to see all of them) that breaks and causes this error to be logged. Also, maybe check "Preserve log" to be sure the panel is not cleared by any indelicate redirection. Sometimes I happen to have a persistent "console" panel, and a cleared "network" panel that leads me to have error in console which is actually unrelated to the visible requests. You should check that.

Or you (but that would be vicious) actually have a hardcoded console.log('TypeError: failed to fetch') in your final .catch ;) and the error is in reality in your .then() but it's hard to believe.

<ImageButton android:src="@drawable/image_btn_src" ... />

Another reason could be; you are accessing your application through nginx using proxy but you did not add gunicorn.sock file for proxy with gunicorn.

You need to add a proxy file path in nginx configuration.

location / {
        include proxy_params;
        proxy_pass http://unix:/home/username/myproject/gunicorn.sock;
    }

Here is a nice tutorial with step by step implementation of this

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04#configure-nginx-to-proxy-pass-to-gunicorn

Note: if you did not created anyname.sock file you have to create if first, either use above or any other method or tutorial to create it.

In version 1.1.1:

• Ctrl+H
• Check the regular exp icon .*
• Search: ><
• Replace: >\n<

<a [routerLink]="" (click)="openSite(SiteUrl)">{{SiteUrl}}</a>

and in your Component.ts

openSite(siteUrl) {
   window.open("//" + siteUrl, '_blank');
}

Use OrderedDicts: http://docs.python.org/2/library/collections.html#collections.OrderedDict

>>> x = OrderedDict((("a", "1"), ("c", '3'), ("b", "2")))
>>> x["d"] = 4
>>> x.keys().index("d")
3
>>> x.keys().index("c")
1

For those using Python 3

>>> list(x.keys()).index("c")
1

According to the UI dialog documentation, the dialog plugin generates something like this:

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   </div>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

Just a reminder: Implicit type var in multiple declaration is not allowed. There might be the following compilation errors.

var Foo = 0, Bar = 0;

Implicitly-typed variables cannot have multiple declarators

Similarly,

var Foo, Bar;

Implicitly-typed variables must be initialized

You may also try standard sql un-pivoting method by using a sequence of logic with the following code.. The following code has 3 steps:

1. create multiple copies for each row using cross join (also creating subject column in this case)
2. create column "marks" and fill in relevant values using case expression ( ex: if subject is science then pick value from science column)

3. remove any null combinations ( if exists, table expression can be fully avoided if there are strictly no null values in base table)

    select *
    from 
    (
       select name, subject,
       case subject
       when 'Maths' then maths
       when 'Science' then science
       when 'English' then english
       end as Marks
   from studentmarks
   Cross Join (values('Maths'),('Science'),('English')) AS Subjct(Subject)
   )as D
   where marks is not null;
   

In my case, the issue was new sites had an implicit deny of all IP addresses unless an explicit allow was created. To fix: Under the site in Features View: Under the IIS Section > IP Address and Domain Restrictions > Edit Feature Settings > Set 'Access for unspecified clients:' to 'Allow'

To be precise, a block ends when it encounter a non-empty line indented at most the same level with the start. This non empty line is not part of that block For example, the following print ends two blocks at the same time:

def foo():
    if bar:
        print "bar"

print "baz" # ends the if and foo at the same time

The indentation level is less-than-or-equal to both the def and the if, hence it ends them both.

Lines with no statement, no matter the indentation, does not matter

def foo():
    print "The line below has no indentation"

    print "Still part of foo"

But the statement that marks the end of the block must be indented at the same level as any existing indentation. The following, then, is an error:

def foo():
    print "Still correct"
   print "Error because there is no block at this indentation"

Generally, if you're used to curly braces language, just indent the code like them and you'll be fine.

BTW, the "standard" way of indenting is with spaces only, but of course tab only is possible, but please don't mix them both.

This is a simple way to identify the application related storage paths of a particular app.

Steps:

1. Have the android device connected to your mac or android emulator open
2. Open the terminal
3. adb shell
4. find .

The "find ." command will list all the files with their paths in the terminal.

./apex/com.android.media.swcodec
./apex/com.android.media.swcodec/etc
./apex/com.android.media.swcodec/etc/init.rc
./apex/com.android.media.swcodec/etc/seccomp_policy
./apex/com.android.media.swcodec/etc/seccomp_policy/mediaswcodec.policy
./apex/com.android.media.swcodec/etc/ld.config.txt
./apex/com.android.media.swcodec/etc/media_codecs.xml
./apex/com.android.media.swcodec/apex_manifest.json
./apex/com.android.media.swcodec/lib
./apex/com.android.media.swcodec/lib/[email protected]

.....

After this, just search for your app with the bundle identifier and you can use adb pull command to download the files to your local directory.

GROUP BY col1, col2, col3

All the above answers are correct. But you can achieve this in just one line. Please try following declaration and you will get all the comma separated values in a String list.

private @Value("#{T(java.util.Arrays).asList(projectProperties['my.list.of.strings'])}") List<String> myList;

And also you need to have the following line defined in your xml configuration.

<util:properties id="projectProperties" location="/project.properties"/>

just replace the path and file name of your properties file. And you are good to go. :)

Hope this helps you. Cheers.

You can access the delegate like this:

MainClass *appDelegate = (MainClass *)[[UIApplication sharedApplication] delegate];

Replace MainClass with the name of your application class.

Then, provided you have a property for the other view controller, you can call something like:

[appDelegate.viewController someMethod];

Just in case you don't want to use stored proc, here's a simple query version

select * 
  from information_schema.columns 
 where table_name = 'aspnet_Membership'
 order by ordinal_position

It displays the current location of the file or directory that you are currently in. for example; if your batch file was in the desktop directory, then "%~dp0" would display the desktop directory. if you wanted it to display the current directory with the current file name you could type "%~dp0%~n0%~x0".

The angular way is shown in the angular docs :)

https://docs.angularjs.org/api/ng/directive/ngReadonly

Here is the example they use:

<body>
    Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
    <input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>

Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).

So basically in your case you would want to do something like below or check out this working example.

<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>

You can use parameter from reCaptcha. By default it uses normal value on data-size, You just have to use compact to fit this on small devices or some-kind small width layouts.

example:

<div class="g-recaptcha" data-size="compact"></div>

You don't need align="center" and float:left. Remove both of these. margin: 0 auto is sufficient.

Add a View:

1. Right-Click View Folder
2. Click Add -> View
3. Click Create a strongly-typed view
4. Select your User class
5. Select List as the Scaffold template

Add a controller and action method to call the view:

public ActionResult Index()
{
    var users = DataContext.GetUsers();
    return View(users);
}

This should be consistent with how Q does it:

if(!Promise.allSettled) {
    Promise.allSettled = function (promises) {
        return Promise.all(promises.map(p => Promise.resolve(p).then(v => ({
            state: 'fulfilled',
            value: v,
        }), r => ({
            state: 'rejected',
            reason: r,
        }))));
    };
}

No need to activate or selection sheets or cells if you're using VBA. You can access it all directly. The code:

Dim rng As Range
For Each rng In Sheets("Feuil2").Range("A1:A333")
    Sheets("Classeur2.csv").Cells(rng.Value, rng.Offset(, 1).Value) = "1"
Next rng

is producing the same result as Joe's code.

If you need to switch sheets for some reasons, use Application.ScreenUpdating = False at the beginning of your macro (and Application.ScreenUpdating=True at the end). This will remove the screenflickering - and speed up the execution.

The negation pseudo-class seems to be what you are looking for.

table:not(.dojoxGrid) {color:red;}

It's not supported by = IE8 though.

I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).

e.g. (from the doc)

     System.out.println("<< Response: " + response.getStatusLine());
     System.out.println(EntityUtils.toString(response.getEntity()));

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

    // process headers using request interceptor
    final Map<String, String> sendHeaders = new HashMap<String, String>();
    if ((headers != null) && (headers.size() > 0)) {
        sendHeaders.putAll(headers);
    }
    if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
        sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
    }
    // request gzip encoding for response
    sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);

    if (sendHeaders.size() > 0) {
        client.addRequestInterceptor(new HttpRequestInterceptor() {

            public void process(final HttpRequest request, final HttpContext context) throws HttpException,
                IOException {
                for (String key : sendHeaders.keySet()) {
                    if (!request.containsHeader(key)) {
                        request.addHeader(key, sendHeaders.get(key));
                    }
                }
            }
        });
    }

    //.... code omitted ....//

}

Very late to the party, but A simple solution is using VBA to create a custom function.

Add the function to VBA in the WorkBook, Worksheet, or a VBA Module

Function LastSegment(S, C)
    LastSegment = Right(S, Len(S) - InStrRev(S, C))
End Function

Then the cell formula

=lastsegment(B1,"/")

in a cell and the string to be searched in cell B1 will populate the cell with the text trailing the last "/" from cell B1. No length limit, no obscure formulas. Only downside I can think is the need for a macro-enabled workbook.

Any user VBA Function can be called this way to return a value to a cell formula, including as a parameter to a builtin Excel function.

If you are going to use the function heavily you'll want to check for the case when the character is not in the string, then string is blank, etc.

Switch the alloc type:

GCHandle handle = GCHandle.Alloc(a, GCHandleType.Normal);

You can use javascript for this provblem. It's retrieve link from browser history.

<script>_x000D_
function goBack() {_x000D_
  window.history.back();_x000D_
}_x000D_
</script>

<button onclick="goBack()">Go Back</button>

I got confused by the answer to this question, so I created a test case in MySQL, hope this helps

The problem with the accepted answer is that it now depends on the caller for the object to be properly validated. I would either remove the RangeAttribute and do the range validation inside the Validate method or I would create a custom attribute subclassing RangeAttribute that takes the name of the required property as an argument on the constructor.

For example:

[AttributeUsage(AttributeTargets.Property, AllowMultiple = false)]
class RangeIfTrueAttribute : RangeAttribute
{
    private readonly string _NameOfBoolProp;

    public RangeIfTrueAttribute(string nameOfBoolProp, int min, int max) : base(min, max)
    {
        _NameOfBoolProp = nameOfBoolProp;
    }

    public RangeIfTrueAttribute(string nameOfBoolProp, double min, double max) : base(min, max)
    {
        _NameOfBoolProp = nameOfBoolProp;
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        var property = validationContext.ObjectType.GetProperty(_NameOfBoolProp);
        if (property == null)
            return new ValidationResult($"{_NameOfBoolProp} not found");

        var boolVal = property.GetValue(validationContext.ObjectInstance, null);

        if (boolVal == null || boolVal.GetType() != typeof(bool))
            return new ValidationResult($"{_NameOfBoolProp} not boolean");

        if ((bool)boolVal)
        {
            return base.IsValid(value, validationContext);
        }
        return null;
    }
}

For anyone who may be interested, another approach is using @media queries to scale the buttons on different viewport widths..

Demo: http://bootply.com/93706

Alternatively, you may also use the CSS3 Flexible Box Model. It's a great way to create flexible layouts that can also be applied to center content like so:

#parent {
    -webkit-box-align:center;
    -webkit-box-pack:center;
    display:-webkit-box;
}

Since you may have more than one legends in a plot, a way to selectively remove just one of the titles without leaving an empty space is to set the name argument of the scale_ function to NULL, i.e.

scale_fill_discrete(name = NULL)

(kudos to @pascal for a comment on another thread)

That is because you are not fully qualifying your cells object. Try this

With Worksheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

Notice the DOT before Cells?

Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.

Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.

As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').

Similar question is private final static attribute vs private final attribute

Hope it helps

Try this.

<asp:Button id="myButton" runat="server" style="display:none" Text="Click Me" />

<script type="text/javascript">
    function ShowButton() {
        var buttonID = '<%= myButton.ClientID %>';
        var button = document.getElementById(buttonID);
        if(button) { button.style.display = 'inherit'; }
    }
</script>

Don't use server-side code to do this because that would require a postback. Instead of using Visibility="false", you can just set a CSS property that hides the button. Then, in javascript, switch that property back whenever you want to show the button again.

The ClientID is used because it can be different from the server ID if the button is inside a Naming Container control. These include Panels of various sorts.

On OS X you can use:

ls -lead

The e option shows ACLs. And ACLs are very important to knowing what the exact permissions on your system are.

Another way to do something similar is with flexbox on a wrapper element, i.e.,

 .row {_x000D_
        display: flex;_x000D_
        justify-content: space-between;_x000D_
    }

  <div class="row">_x000D_
        <div>Left</div>_x000D_
        <div>Right</div>_x000D_
    </div>_x000D_
_x000D_
   

A react js solution

 handleChange: function(e) {
    if (e.key == 'Enter') {
      console.log('test');
    }


 <div>
    <Input type="text"
       ref = "input"
       placeholder="hiya"
       onKeyPress={this.handleChange}
    />
 </div>

Check this example of post the array of different types

function PostArray() {
    var myObj = [
        { 'fstName': 'name 1', 'lastName': 'last name 1', 'age': 32 }
      , { 'fstName': 'name 2', 'lastName': 'last name 1', 'age': 33 }
    ];

    var postData = JSON.stringify({ lst: myObj });
    console.log(postData);

    $.ajax({
        type: "POST",
        url: urlWebMethods + "/getNames",
        data: postData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response.d);
        },
        failure: function (msg) {
            alert(msg.d);
        }
    });
}

If using a WebMethod in C# you can retrieve the data like this

[WebMethod]
    public static string getNames(IEnumerable<object> lst)
    {
        string names = "";
        try
        {
            foreach (object item in lst)
            {
                Type myType = item.GetType();
                IList<PropertyInfo> props = new List<PropertyInfo>(myType.GetProperties());

                foreach (PropertyInfo prop in props)
                {
                    if(prop.Name == "Values")
                    {
                        Dictionary<string, object> dic = item as Dictionary<string, object>;
                        names += dic["fstName"];
                    }
                }
            }
        }
        catch (Exception ex)
        {
             names = "-1";
        }
        return names;
    }

Example in POST an array of objects with $.ajax to C# WebMethod

You can tell your users to add your From address to their contacts when they complete their order, which, if they do so, will help a lot.

Otherwise, I would try to get a log from some of your users. Sometimes they have details about why it was flagged as spam in the headers of the message, which you could use to tweak the text.

Other things you can try:

• Put your site name or address in the subject
• Keep all links in the message pointing to your domain (and not email.com)
• Put an address or other contact information in the email

Integrating SearchView with RecyclerView

1) Add SearchView Item in Menu

SearchView can be added as actionView in menu using

app:useActionClass = "android.support.v7.widget.SearchView" .

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
    android:id="@+id/searchBar"
    app:showAsAction="always"
    app:actionViewClass="android.support.v7.widget.SearchView"
    />
</menu>

2) Implement SearchView.OnQueryTextListener in your Activity

SearchView.OnQueryTextListener has two abstract methods. So your activity skeleton would now look like this after implementing SearchView text listener.

YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{

   public boolean onQueryTextSubmit(String query)

   public boolean onQueryTextChange(String newText) 

}

3) Set up SerchView Hint text, listener etc

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);

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

    SearchView searchView = (SearchView) searchItem.getActionView();
    searchView.setQueryHint("Search People");
    searchView.setOnQueryTextListener(this);
    searchView.setIconified(false);

    return true;
}

4) Implement SearchView.OnQueryTextListener

This is how you can implement abstract methods of the listener.

@Override
public boolean onQueryTextSubmit(String query) {

    // This method can be used when a query is submitted eg. creating search history using SQLite DB

    Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {

    adapter.filter(newText);
    return true;
}

5) Write a filter method in your RecyclerView Adapter.

You can come up with your own logic based on your requirement. Here is the sample code snippet to show the list of Name which contains the text typed in the SearchView.

public void filter(String queryText)
{
    list.clear();

    if(queryText.isEmpty())
    {
        list.addAll(copyList);
    }
    else
    {

        for(String name: copyList)
        {
            if(name.toLowerCase().contains(queryText.toLowerCase()))
            {
                list.add(name);
            }
        }

    }

    notifyDataSetChanged();
}

In your particular example perhaps you do not have to perform any checks at all. Is that possible that New-Object return null? I have never seen that. The command should fail in case of a problem and the rest of the code in the example will not be executed. So why should we do that checks at all?

Only in the code like below we need some checks (explicit comparison with $null is the best):

# we just try to get a new object
$ie = $null
try {
    $ie = New-Object -ComObject InternetExplorer.Application
}
catch {
    Write-Warning $_
}

# check and continuation
if ($ie -ne $null) {
    ...
}

I just installed Jest as global, ran jest myFileToTest.spec.js, and it worked.

You can also use

cd %localhost%

to set the directory to the folder the batch file was opened from. Your script would look like this:

@echo off
cd %localhost%
echo .> dblank.txt

Make sure you set the directory before you use the command to create the text file.

Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:

• pods — a way to group containers together
• replication controllers — a way to handle the lifecycle of containers
• labels — a way to find and query containers, and
• services — a set of containers performing a common function.

So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.

With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.

Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).

When asked, I tend to say:

1. Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).

2. If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.

3. Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.

I think this is better solution. Unlike simply selecting in onclick event, it doesn't prevent selecting/editing text with mouse. It works with major rendering engines including IE8.

$('input').on('focus', function (e) {
    $(this)
        .one('mouseup', function () {
            $(this).select();
            return false;
        })
        .select();
});

You are trying to min-max scale the values of audio between -1 and +1 and image between 0 and 255.

Using sklearn.preprocessing.minmax_scale, should easily solve your problem.

e.g.:

audio_scaled = minmax_scale(audio, feature_range=(-1,1))

and

shape = image.shape
image_scaled = minmax_scale(image.ravel(), feature_range=(0,255)).reshape(shape)

note: Not to be confused with the operation that scales the norm (length) of a vector to a certain value (usually 1), which is also commonly referred to as normalization.

I used a simpler solution found partly here:
How to sort details with Date and time in sql server ?

Call GoogleMap.setMyLocationEnabled(true) in your Activity, and add this 2 lines code in the Manifest:

Using CSS3: http://www.w3schools.com/cssref/sel_nth-child.asp

If that's not an option for any reason, you could try giving the list items classes:

<ul>
<li class="one"></li>
<li class="two"></li>
<li class="three"></li>
...
</ul>

Then in your css:

li.one{display:none}/*hide first li*/
li.three{display:none}/*hide third li*/

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

Show names and mount point destinations of volumes used by a container:

docker container inspect \

This is compatible with Docker 1.13.

You can use javascript to access elements on the page and modify their contents. So for example you might have a page with some HTML markup like so:

<div id="MyEdit">
    This text will change
</div>

You can use javascript to change the content like so...

document.getElementById("MyEdit").innerHTML = "My new text!";?

Here is a working example

You can also look at using the JQuery javascript library for DOM manipulation, it has some great features to make things like this very easy.

For example, with JQuery, you could do this to acheive the same result...

$("#MyEdit").html("My new text!");

Here is a working example of the JQuery version

Based on this example you provided in your post. The following JQuery would work for you:

var x = "hello wolrd";
$("p").html(x);

Here is the working version

Using a P tag like this however is not recommended. You would ideally want to use an element with a unique ID so you can ensure you are selecting the correct one with JQuery.

The key is the sql query, which you will set up as a string:

$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";

Note that there are a lot of ways to specify NOT. Another one that works just as well is:

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA != 'x' AND columbB != 'y'";

Here is a full example of how to use it:

$link = mysql_connect($dbHost,$dbUser,$dbPass) or die("Unable to connect to database");
mysql_select_db("$dbName") or die("Unable to select database $dbName");
$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";
$result=mysql_query($sqlquery);

while ($row = mysql_fetch_assoc($result) {
//do stuff
}

You can do whatever you would like within the above while loop. Access each field of the table as an element of the $row array which means that $row['field1'] will give you the value for field1 on the current row, and $row['field2'] will give you the value for field2.

Note that if the column(s) could have NULL values, those will not be found using either of the above syntaxes. You will need to add clauses to include NULL values:

$sqlquery = "SELECT field1, field2 FROM table WHERE (NOT columnA = 'x' OR columnA IS NULL) AND (NOT columbB = 'y' OR columnB IS NULL)";

puts adds a new line to the end of each argument if there is not one already.

print does not add a new line.

For example:

puts [[1,2,3], [4,5,nil]] Would return:

1
2
3
4
5

Whereas print [[1,2,3], [4,5,nil]] would return:

[[1,2,3], [4,5,nil]]

Notice how puts does not output the nil value whereas print does.

According to the official default HTML stylesheet, there is no defined default link color. However, you can find out the default your browser uses by either taking a screenshot and using the pipette tool in any decent graphic editor or using the developer tools of your browser (select an a element, look for computed values>color).

.pyc contain the compiled bytecode of Python source files. The Python interpreter loads .pyc files before .py files, so if they're present, it can save some time by not having to re-compile the Python source code. You can get rid of them if you want, but they don't cause problems, they're not big, and they may save some time when running programs.

This looks for sequences of an uppercase letter followed by one or more lowercase letters. Consecutive uppercase letters will not match, as only one is allowed at a time, and it must be followed by a lowercase one.

>>> dict(zip([1, 2, 3, 4], ['a', 'b', 'c', 'd']))
{1: 'a', 2: 'b', 3: 'c', 4: 'd'}

If they are not the same size, zip will truncate the longer one.

It turned out that all I needed to do was change the 'path' to:

"C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem; C:\Program Files (x86)\Java; C:\Program Files (x86)\Java\jdk1.6.0_14\bin"

that did it :)

A quick definition of the "permanent generation":

"The permanent generation is used to hold reflective data of the VM itself such as class objects and method objects. These reflective objects are allocated directly into the permanent generation, and it is sized independently from the other generations." [ref]

In other words, this is where class definitions go (and this explains why you may get the message OutOfMemoryError: PermGen space if an application loads a large number of classes and/or on redeployment).

Note that PermSize is additional to the -Xmx value set by the user on the JVM options. But MaxPermSize allows for the JVM to be able to grow the PermSize to the amount specified. Initially when the VM is loaded, the MaxPermSize will still be the default value (32mb for -client and 64mb for -server) but will not actually take up that amount until it is needed. On the other hand, if you were to set BOTH PermSize and MaxPermSize to 256mb, you would notice that the overall heap has increased by 256mb additional to the -Xmx setting.

Each elapsed event will fire in the same thread unless a previous Elapsed is still running.

So it handles the collision for you

try putting this in a console

static void Main(string[] args)
{
    Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);
    var timer = new Timer(1000);
    timer.Elapsed += timer_Elapsed;
    timer.Start();
    Console.ReadLine();
}

static void timer_Elapsed(object sender, ElapsedEventArgs e)
{
    Thread.Sleep(2000);
    Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);
}

you will get something like this

10
6
12
6
12

where 10 is the calling thread and 6 and 12 are firing from the bg elapsed event. If you remove the Thread.Sleep(2000); you will get something like this

10
6
6
6
6

Since there are no collisions.

But this still leaves u with a problem. if u are firing the event every 5 seconds and it takes 10 seconds to edit u need some locking to skip some edits.

While I agree that the constant need to sort a map is probably a smell, I think the following code is the easiest way to do it without using a different data structure.

public class MapUtilities {

public static <K, V extends Comparable<V>> List<Entry<K, V>> sortByValue(Map<K, V> map) {
    List<Entry<K, V>> entries = new ArrayList<Entry<K, V>>(map.entrySet());
    Collections.sort(entries, new ByValue<K, V>());
    return entries;
}

private static class ByValue<K, V extends Comparable<V>> implements Comparator<Entry<K, V>> {
    public int compare(Entry<K, V> o1, Entry<K, V> o2) {
        return o1.getValue().compareTo(o2.getValue());
    }
}

}

And here is an embarrassingly incomplete unit test:

public class MapUtilitiesTest extends TestCase {
public void testSorting() {
    HashMap<String, Integer> map = new HashMap<String, Integer>();
    map.put("One", 1);
    map.put("Two", 2);
    map.put("Three", 3);

    List<Map.Entry<String, Integer>> sorted = MapUtilities.sortByValue(map);
    assertEquals("First", "One", sorted.get(0).getKey());
    assertEquals("Second", "Two", sorted.get(1).getKey());
    assertEquals("Third", "Three", sorted.get(2).getKey());
}

}

The result is a sorted list of Map.Entry objects, from which you can obtain the keys and values.

As mentioned above, put gem: --no-document in your gem file. However, the system-wide gemrc will not always necessarily go into /etc/gemrc. If you are using RVM, or you have Ruby installed under /usr/local/bin, it needs to go in a different location. You can find this location by running irb and typing...

require 'rubygems'
Gem::ConfigFile::SYSTEM_WIDE_CONFIG_FILE

See the original post on this over here.

Avoid using Xcode to rename files in a folder reference. If you rename a file using Xcode, it will be marked for commit. If you later delete it before the commit, you will end up with this error.

For Xcode 9.1 and Swift 4:

1. Import StoreKit:

import StoreKit

2.Conform the protocol

SKStoreProductViewControllerDelegate

3.Implement the protocol

func openStoreProductWithiTunesItemIdentifier(identifier: String) {
    let storeViewController = SKStoreProductViewController()
    storeViewController.delegate = self

    let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier]
    storeViewController.loadProduct(withParameters: parameters) { [weak self] (loaded, error) -> Void in

        if loaded {
            // Parent class of self is UIViewContorller
            self?.present(storeViewController, animated: true, completion: nil)
        }
    }   
}

3.1

func productViewControllerDidFinish(_ viewController: SKStoreProductViewController) {
    viewController.dismiss(animated: true, completion: nil)
}

4. How to use:

openStoreProductWithiTunesItemIdentifier(identifier: "here_put_your_App_id")

Note:

It is very important to enter the exact ID of your APP. Because this cause error (not show the error log, but nothing works fine because of this)

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's a reliable solution. My apologies for length - C#'s introspection API makes this suprisingly difficult.

/// <summary>
/// Test if a type implements IList of T, and if so, determine T.
/// </summary>
public static bool TryListOfWhat(Type type, out Type innerType)
{
    Contract.Requires(type != null);

    var interfaceTest = new Func<Type, Type>(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IList<>) ? i.GetGenericArguments().Single() : null);

    innerType = interfaceTest(type);
    if (innerType != null)
    {
        return true;
    }

    foreach (var i in type.GetInterfaces())
    {
        innerType = interfaceTest(i);
        if (innerType != null)
        {
            return true;
        }
    }

    return false;
}

Example usage:

    object value = new ObservableCollection<int>();
Type innerType;
TryListOfWhat(value.GetType(), out innerType).Dump();
innerType.Dump();

Returns

True
typeof(Int32)

The PDF/pdflib extension documentation in PHP is sparse (something that has been noted in bugs.php.net) - I reccommend you use the Zend library.

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit.

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article, for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.

Another approach to solve this is to use the following module.

node_extra_ca_certs_mozilla_bundle

This module can work without any code modification by generating a PEM file that includes all root and intermediate certificates trusted by Mozilla. You can use the following environment variable (Works with Nodejs v7.3+),

NODE_EXTRA_CA_CERTS

To generate the PEM file to use with the above environment variable. You can install the module using:

npm install --save node_extra_ca_certs_mozilla_bundle

and then launch your node script with an environment variable.

NODE_EXTRA_CA_CERTS=node_modules/node_extra_ca_certs_mozilla_bundle/ca_bundle/ca_intermediate_root_bundle.pem node your_script.js

Other ways to use the generated PEM file are available at:

https://github.com/arvind-agarwal/node_extra_ca_certs_mozilla_bundle

NOTE: I am the author of the above module.

def mymap = [name:"Gromit", id:1234]
def x = mymap.find{ it.key == "likes" }?.value
if(x)
    println "x value: ${x}"

println x.getClass().name

?. checks for null and does not create an exception in Groovy. If the key does not exist, the result will be a org.codehaus.groovy.runtime.NullObject.

In case anyone still looking for a solution. This worked for me.

Python adds the folder containing the script you launch to the PYTHONPATH, so if you run

python application/app2/some_folder/some_file.py

Only the folder application/app2/some_folder is added to the path (not the base dir that you're executing the command in). Instead, run your file as a module and add a __init__.py in your some_folder directory.

python -m application.app2.some_folder.some_file

This will add the base dir to the python path, and then classes will be accessible via a non-relative import.

Simple way to access the Url Try this Code

 $.ajax({
     type: "POST",
      url: '/Controller/Search', 
     data: "{queryString:'" + searchVal + "'}",
     contentType: "application/json; charset=utf-8",
     dataType: "html",
     success: function (data) {
     alert("here" + data.d.toString());
    });

var total = 0;
$.each(someArray,function() {
    total += parseInt(this, 10);
});

both are fine.

text/xxx means that in case the program does not understand xxx it makes sense to show the file to the user as plain text. application/xxx means that it is pointless to show it.

Here is a resource you can edit and use Download Source Code or see live demo here http://purpledesign.in/blog/pop-out-a-form-using-jquery-and-javascript/

Add a Button or link to your page like this

<p><a href="#inline">click to open</a></p>

“#inline” here should be the “id” of the that will contain the form.

<div id="inline">
 <h2>Send us a Message</h2>
 <form id="contact" name="contact" action="#" method="post">
 <label for="email">Your E-mail</label>
 <input type="email" id="email" name="email" class="txt">
 <br>
 <label for="msg">Enter a Message</label>
 <textarea id="msg" name="msg" class="txtarea"></textarea>
<button id="send">Send E-mail</button>
 </form>
</div>

Include these script to listen of the event of click. If you have an action defined in your form you can use “preventDefault()” method

<script type="text/javascript">
 $(document).ready(function() {
$(".modalbox").fancybox();
$("#contact").submit(function() { return false; });
$("#send").on("click", function(){
var emailval = $("#email").val();
var msgval = $("#msg").val();
var msglen = msgval.length;
var mailvalid = validateEmail(emailval);
if(mailvalid == false) {
$("#email").addClass("error");
}
else if(mailvalid == true){
 $("#email").removeClass("error");
 }

 if(msglen < 4) {
 $("#msg").addClass("error");
 }
 else if(msglen >= 4){
 $("#msg").removeClass("error");
 }

 if(mailvalid == true && msglen >= 4) {
 // if both validate we attempt to send the e-mail
 // first we hide the submit btn so the user doesnt click twice
 $("#send").replaceWith("<em>sending...</em>");
 //This will post it to the php page
 $.ajax({
 type: 'POST',
 url: 'sendmessage.php',
 data: $("#contact").serialize(),
 success: function(data) {
 if(data == "true") {
 $("#contact").fadeOut("fast", function(){
//Display a message on successful posting for 1 sec
 $(this).before("<p><strong>Success! Your feedback has been sent, thanks :)</strong></p>");
 setTimeout("$.fancybox.close()", 1000);
 });
 }
 }
 });
 }
 });
 });
</script>

You can add anything you want to do in your PHP file.

Following is working for me on dotnet 1.0.1:

./ourView.cshtml

@Html.Partial(
  "_ourPartial.cshtml",
  new ViewDataDictionary(this.Vi??ewData) {
    {
      "hi", "hello" 
    } 
  }
);

./_ourPartial.cshtml

<h1>@this.ViewData["hi"]</h1>

Since the aggregates string can be longer than 4000 bytes, you can't use the LISTAGG function. You could potentially create a user-defined aggregate function that returns a CLOB rather than a VARCHAR2. There is an example of a user-defined aggregate that returns a CLOB in the original askTom discussion that Tim links to from that first discussion.

I put commit .gitignore, which is a courtesy to other who may build my project that the following files are derived and should be ignored.

I usually do a hybrid. I like to make makefile generate the .gitignore file since the makefile will know all the files associated with the project -derived or otherwise. Then have a top level project .gitignore that you check in, which would ignore the generated .gitignore files created by the makefile for the various sub directories.

So in my project, I might have a bin sub directory with all the built executables. Then, I'll have my makefile generate a .gitignore for that bin directory. And in the top directory .gitignore that lists bin/.gitignore. The top one is the one I check in.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

simply insert new line where necessary

sql="
SELECT c1, c2
from Table1, Table2
where ...
"

shell will be looking for the closing quotation mark

show variables where Variable_name='hostname'; 

That could help you !!

Assuming they always exist and are not part of your data, this will work:

declare @string varchar(8000) = '23;chair,red [$3]'
select substring(@string, charindex(';', @string) + 1, charindex(' [', @string) - charindex(';', @string) - 1)

The best I've seen is Zend Guard.

As documented here create-react-app will only import environment variables beginning with REACT_APP_, so the PUBLIC_URL, I believe, as mentioned by @redbmk, comes from the homepage setting in the package.json file.

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

In Simple Words -

The export statement is used when creating JavaScript modules to export functions, objects, or primitive values from the module so they can be used by other programs with the import statement.

The answers given so far are not ideal because they require a lot of needless work resolving merge conflicts, or they make too many assumptions which are frequently false. This is how to do it perfectly. The link is to my own site.

How to Commit to a Different Branch in git

You have uncommited changes on my_branch that you want to commit to master, without committing all the changes from my_branch.

Example

git merge master
git stash -u
git checkout master
git stash apply
git reset
git add example.js
git commit
git checkout .
git clean -f -d
git checkout my_branch
git merge master
git stash pop

Explanation

Start by merging master into your branch, since you'll have to do that eventually anyway, and now is the best time to resolve any conflicts.

The -u option (aka --include-untracked) in git stash -u prevents you from losing untracked files when you later do git clean -f -d within master.

After git checkout master it is important that you do NOT git stash pop, because you will need this stash later. If you pop the stash created in my_branch and then do git stash in master, you will cause needless merge conflicts when you later apply that stash in my_branch.

git reset unstages everything resulting from git stash apply. For example, files that have been modified in the stash but do not exist in master get staged as "deleted by us" conflicts.

git checkout . and git clean -f -d discard everything that isn't committed: all changes to tracked files, and all untracked files and directories. They are already saved in the stash and if left in master would cause needless merge conflicts when switching back to my_branch.

The last git stash pop will be based on the original my_branch, and so will not cause any merge conflicts. However, if your stash contains untracked files which you have committed to master, git will complain that it "Could not restore untracked files from stash". To resolve this conflict, delete those files from your working tree, then git stash pop, git add ., and git reset.

Simple printf() function from O'Reilly's Python Cookbook.

import sys
def printf(format, *args):
    sys.stdout.write(format % args)

Example output:

i = 7
pi = 3.14159265359
printf("hi there, i=%d, pi=%.2f\n", i, pi)
# hi there, i=7, pi=3.14

Here's how I did it:

table.getSelectionModel().addListSelectionListener(new ListSelectionListener(){
        public void valueChanged(ListSelectionEvent event) {
            // do some actions here, for example
            // print first column value from selected row
            System.out.println(table.getValueAt(table.getSelectedRow(), 0).toString());
        }
    });

This code reacts on mouse click and item selection from keyboard.

One line answer. You can use filter function to get result.

var array = [_x000D_
    { name:"string 1", value:"this", other: "that" },_x000D_
    { name:"string 2", value:"this", other: "that" }_x000D_
];_x000D_
_x000D_
console.log(array.filter(function(arr){return arr.name == 'string 1'})[0]);

Try \r\n in place of \n

The difference between \n and \r\n

It should be noted that this is applicable to line returns in emails. For other scenarios, please refer to rokjarc's answer.

If you have short strings you should be able to create a few LIKE patterns ('[^a-zA-Z0-9]', '[^a-zA-Z0-9][^a-zA-Z0-9]', ...) to match strings of different length. Otherwise you should use CLR user defined function and a proper regular expression - Regular Expressions Make Pattern Matching And Data Extraction Easier.

Use the builtin function zip():

In Python 3:

z = list(zip(x,y))

In Python 2:

z = zip(x,y)

@media only screen and (max-width: 1026px) { 
  #fadeshow1 { 
    display: none; 
  } 
}

Any time the screen is less than 1026 pixels wide, anything inside the { } will apply.

Some browsers don't support media queries. You can get round this using a javascript library like Respond.JS

<script>
    $(document).ready(function(){
        $('#connectBtn').click(function(e){
            e.preventDefault();
        })
    });
</script>

This will prevent the default action.

I had a case that I used DBMS where I had to fulfill a db connection form.

I put SID into the Database field and in the dropdown, next to the field, I had had 'Service Name' value instead of 'SID' value.
(normally I don't use Oracle database so I've not been aware of the difference)

That was the reason I got the error message.

For PowerShell in Windows

I was having trouble with PoSH and the Start-SshAgent / Add-SshKey commands, so I whipped up a quick script that might help some folks out. This is intended to be added to your PowerShell profile which you can edit by executing notepad $PROFILE

if ($(Get-Process ssh-agent) -eq $null)
{
    $ExecutionContext.InvokeCommand.ExpandString($(ssh-agent -c).Replace("setenv", "set"));
}

It will detect if the ssh-agent is running or not and only execute if there is no agent running already. Please note that $ExecutionContext.InvokeCommand.ExpandString is a pretty dangerous command so you may not want to use this solution if you are using an untrusted copy of ssh-agent.

I got the same problem and I just added the content of ~/.ssh/id_rsa.pub to my account in GitHub. After that just try again git push origin master, it should work.

First of all, you should install SignalR.Host.Self on the server application and SignalR.Client on your client application by nuget :

PM> Install-Package SignalR.Hosting.Self -Version 0.5.2

PM> Install-Package Microsoft.AspNet.SignalR.Client

Then add the following code to your projects ;)

(run the projects as administrator)

Server console app:

using System;
using SignalR.Hubs;

namespace SignalR.Hosting.Self.Samples {
    class Program {
        static void Main(string[] args) {
            string url = "http://127.0.0.1:8088/";
            var server = new Server(url);

            // Map the default hub url (/signalr)
            server.MapHubs();

            // Start the server
            server.Start();

            Console.WriteLine("Server running on {0}", url);

            // Keep going until somebody hits 'x'
            while (true) {
                ConsoleKeyInfo ki = Console.ReadKey(true);
                if (ki.Key == ConsoleKey.X) {
                    break;
                }
            }
        }

        [HubName("CustomHub")]
        public class MyHub : Hub {
            public string Send(string message) {
                return message;
            }

            public void DoSomething(string param) {
                Clients.addMessage(param);
            }
        }
    }
}

Client console app:

using System;
using SignalR.Client.Hubs;

namespace SignalRConsoleApp {
    internal class Program {
        private static void Main(string[] args) {
            //Set connection
            var connection = new HubConnection("http://127.0.0.1:8088/");
            //Make proxy to hub based on hub name on server
            var myHub = connection.CreateHubProxy("CustomHub");
            //Start connection

            connection.Start().ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error opening the connection:{0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine("Connected");
                }

            }).Wait();

            myHub.Invoke<string>("Send", "HELLO World ").ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error calling send: {0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine(task.Result);
                }
            });

            myHub.On<string>("addMessage", param => {
                Console.WriteLine(param);
            });

            myHub.Invoke<string>("DoSomething", "I'm doing something!!!").Wait();


            Console.Read();
            connection.Stop();
        }
    }
}

One advantage that the aforementioned copy-webpack-plugin brings that hasn't been explained before is that all the other methods mentioned here still bundle the resources into your bundle files (and require you to "require" or "import" them somewhere). If I just want to move some images around or some template partials, I don't want to clutter up my javascript bundle file with useless references to them, I just want the files emitted in the right place. I haven't found any other way to do this in webpack. Admittedly it's not what webpack originally was designed for, but it's definitely a current use case. (@BreakDS I hope this answers your question - it's only a benefit if you want it)

Have you tried the uncurl package (https://github.com/spulec/uncurl)? You can install it via pip, pip install uncurl. Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },
    cookies={},
)

If you need proxy support you can do this:

  if needProxy == False:
    returnCode, urlReturnResponse = urllib.urlretrieve( myUrl, fullJpegPathAndName )
  else:
    proxy_support = urllib2.ProxyHandler({"https":myHttpProxyAddress})
    opener = urllib2.build_opener(proxy_support)
    urllib2.install_opener(opener)
    urlReader = urllib2.urlopen( myUrl ).read() 
    with open( fullJpegPathAndName, "w" ) as f:
      f.write( urlReader )

Additional musings. You said insmod crashes. Insmod loads modules. The modules are built in another compile operation from building the kernel. Kernel and modules have to be built from the same headers and so forth. Are all the modules built during the kernel build, or are they "existing"?

The other idea, and something I know little about, is svn externals, which (if used) can affect what is checked out to your project. Look and see if this is any different when exporting.

Because the SCHEDULER_ADMIN role is a powerful role allowing a grantee to execute code as any user, you should consider granting individual Scheduler system privileges instead. Object and system privileges are granted using regular SQL grant syntax. An example is if the database administrator issues the following statement:

GRANT CREATE JOB TO scott;

After this statement is executed, scott can create jobs, schedules, or programs in his schema.

AHHH!!! This looks so wrong it hurts my head. Try something more like this...

<?php
include('db.php');

$result = mysql_query('SELECT `id`, `name`, `description`, `icon` FROM `staff` ORDER BY `id` DESC LIMIT 20') or die(mysql_error());
$rows = array();
while($row = mysql_fetch_assoc($result)){
    $rows[] = $row;
}

echo json_encode($rows);
?>

• When iterating over mysql_num_rows you should use < not <=. You should also cache this value (save it to a variable) instead of having it re-count every loop. Who knows what it's doing under the hood... (might be efficient, I'm not really sure)
• You don't need to copy out each value explicitly like that... you're just making this harder on yourself. If the query is returning more values than you've listed there, list only the ones you want in your SQL.
• mysql_fetch_array returns the values both by key and by int. You not using the indices, so don't fetch em.

If this really is a problem with json_encode, then might I suggest replacing the body of the loop with something like

$rows[] = array_map('htmlentities',$row);

Perhpas there are some special chars in there that are mucking things up...

In my case, I messed up the connectionString property in a publish profile, trying to access the wrong database (Initial Catalog). Entity Framework then complains that the entities do not match the database, and rightly so.

I'd prefer mapping after making sure the value is available

private String getStringIfObjectIsPresent(Optional<Object> object) {
   Object ob = object.orElseThrow(MyCustomException::new);
    // do your mapping with ob
   String result = your-map-function(ob);
  return result;
}

or one liner

private String getStringIfObjectIsPresent(Optional<Object> object) {
   return your-map-function(object.orElseThrow(MyCustomException::new));
}

UPDATE 2017-12-13

You can now download the extension directly from the marketplace.

As of Visual Studio Code 1.7.1 dragging or opening the extension does not work any more. In order to install it manually you need to:

• open the extensions sidebar
• click on the ellipsis in the right upper corner
• choose Install from VSIX

Old Method

According to the documentation it is possible to download an extension directly:

An extension's direct download URL is in the form:

https://${publisher}.gallery.vsassets.io/_apis/public/gallery/publisher/${publisher}/extension/${extension name}/${version}/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage

This means that in order to download the extension you need to know

• the publisher name
• the version
• the extension name

You can find all this information in the URL.

Example

Here's an example for downloading an installing the C# v1.3.0 extension:

Publisher, Extension and Version

You can find the publisher and the extension names on the extension's homepage inside its URL:

https://marketplace.visualstudio.com/items?itemName=ms-vscode.csharp

Here the publisher is ms-vscode and the extension name is csharp.

The version can be found on the right side in the More Info area.

To download it you need to create a link from the template above:

https://ms-vscode.gallery.vsassets.io/_apis/public/gallery/publisher/ms-vscode/extension/csharp/1.3.0/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage

All packages will have the same name Microsoft.VisualStudio.Services.VSIXPackage, so you'll need to rename it after downloading if you want to know what package it was later.

Installation

In order to install the extension

• Rename the file and give it the *.vsix extension
• Open Visual Studio Code, go to menu File → Open File... or Ctrl + O and select the .vsix file
• If everything went fine, you should see this message at the top of the window:

Extension was successfully installed. Restart to enable it.

An updated version of the correct answer for .NET 4.5 would be.

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxImage.Question) 
    == MessageBoxResult.Yes)  
{
// If yes
}
else  
{
// If no
}

Additionally, if you wanted to bind the button to a command in a view model you could use the following. This is compatible with MvvmLite:

public RelayCommand ShowPopUpCommand
{
   get
   {
   return _showPopUpCommand ??
      (_showPopUpCommand = new RelayCommand(
         () =>
               {
                // Put if statement here
               }
      }));
   }
}

You have several options depending on what you're looking for. Workbook.Path returns the path of a saved workbook. Application.Path returns the path to the Excel executable. CurDir returns the current working path, this probably defaults to your My Documents folder or similar.

You can also use the windows scripting shell object's .CurrentDirectory property.

Set wshell = CreateObject("WScript.Shell")
Debug.Print wshell.CurrentDirectory

But that should get the same result as just

Debug.Print CurDir

git bash is a shell where:

• the running process is sh.exe (packaged with msysgit, as share/WinGit/Git Bash.vbs)
• git is a known command
• $HOME is defined

See "Fix msysGit Portable $HOME location":

On a Windows 64:

C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"

This differs from git-cmd.bat, which provides git commands in a plain DOS command prompt.

A tool like GitHub for Windows (G4W) provides different shell for git (including a PowerShell one)

Update April 2015:

Note: the git bash in msysgit/Git for windows 1.9.5 is an old one:

GNU bash, version 3.1.20(4)-release (i686-pc-msys)
Copyright (C) 2005 Free Software Foundation, Inc.

But with the phasing out of msysgit (Q4 2015) and the new Git For Windows (Q2 2015), you now have Git for Windows 2.3.5.
It has a much more recent bash, based on the 64bits msys2 project, an independent rewrite of MSYS, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. msys2 comes with its own installer too.

The git bash is now (with the new Git For Windows):

GNU bash, version 4.3.33(3)-release (x86_64-pc-msys)
Copyright (C) 2013 Free Software Foundation, Inc.

Original answer (June 2013) More precisely, from msygit wiki:

Historically, Git on Windows was only officially supported using Cygwin.
To help make a native Windows version, this project was started, based on the mingw fork.

To make the milky 'soup' of project names more clear, we say like this:

• msysGit - is the name of this project, a build environment for Git for Windows, which releases the official binaries
• MinGW - is a minimalist development environment for native Microsoft Windows applications.
  It is really a very thin compile-time layer over the Microsoft Runtime; MinGW programs are therefore real Windows programs, with no concept of Unix-style paths or POSIX niceties such as a fork() call
• MSYS - is a Bourne Shell command line interpreter system, is used by MinGW (and others), was forked in the past from Cygwin
• Cygwin - a Linux like environment, which was used in the past to build Git for Windows, nowadays has no relation to msysGit

So, your two lines description about "git bash" are:

"Git bash" is a msys shell included in "Git for Windows", and is a slimmed-down version of Cygwin (an old version at that), whose only purpose is to provide enough of a POSIX layer to run a bash.

Reminder:

msysGit is the development environment to compile Git for Windows. It is complete, in the sense that you just need to install msysGit, and then you can build Git. Without installing any 3rd-party software.

msysGit is not Git for Windows; that is an installer which installs Git -- and only Git.

See more in "Difference between msysgit and Cygwin + git?".

Change 1D array into 2D array without using Numpy.

l = [i for i in range(1,21)]
part = 3
new = []
start, end = 0, part


while end <= len(l):
    temp = []
    for i in range(start, end):
        temp.append(l[i])
    new.append(temp)
    start += part
    end += part
print("new values:  ", new)


# for uneven cases
temp = []
while start < len(l):
    temp.append(l[start])
    start += 1
    new.append(temp)
print("new values for uneven cases:   ", new)

onClick={this.handleRemove.bind(this, id)}

Try this small example:

Code:

try {
    Path tmpDir = Files.createTempDirectory("tmpDir");
    System.out.println(tmpDir.toString());
    Files.delete(tmpDir);
} catch (IOException e) {
    e.printStackTrace();
}

Imports:
java.io.IOException
java.nio.file.Files
java.nio.file.Path

Console output on Windows machine:
C:\Users\userName\AppData\Local\Temp\tmpDir2908538301081367877

Comment:
Files.createTempDirectory generates unique ID atomatically - 2908538301081367877.

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

public ActionResult Index()
{
    return View();
}

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

[HttpPost]
public ActionResult AddUser(PersonModel model)
{
    if (model != null)
    {
        return Json("Success");
    }
    else
    {
        return Json("An Error Has occoured");
    }
}

So now when the post happens you can get all the posted data in the model parameter of action.

Update:

For asp.net core, to get JSON data as your action parameter you should add the [FromBody] attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController] attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)

Sometime your code syntax has error, like you use " in ", it must be " ...'...." For help you quickly detect problems, you click Design button, vs try to render, and it will show the line of error

I am getting result to Fragment DashboardLiveWall(calling fragment) from Fragment LiveWallFilterFragment(receiving fragment) Like this...

 LiveWallFilterFragment filterFragment = LiveWallFilterFragment.newInstance(DashboardLiveWall.this ,"");

 getActivity().getSupportFragmentManager().beginTransaction(). 
 add(R.id.frame_container, filterFragment).addToBackStack("").commit();

where

public static LiveWallFilterFragment newInstance(Fragment targetFragment,String anyDummyData) {
        LiveWallFilterFragment fragment = new LiveWallFilterFragment();
        Bundle args = new Bundle();
        args.putString("dummyKey",anyDummyData);
        fragment.setArguments(args);

        if(targetFragment != null)
            fragment.setTargetFragment(targetFragment, KeyConst.LIVE_WALL_FILTER_RESULT);
        return fragment;
    }

setResult back to calling fragment like

private void setResult(boolean flag) {
        if (getTargetFragment() != null) {
            Bundle bundle = new Bundle();
            bundle.putBoolean("isWorkDone", flag);
            Intent mIntent = new Intent();
            mIntent.putExtras(bundle);
            getTargetFragment().onActivityResult(getTargetRequestCode(),
                    Activity.RESULT_OK, mIntent);
        }
    }

onActivityResult

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == KeyConst.LIVE_WALL_FILTER_RESULT) {

                Bundle bundle = data.getExtras();
                if (bundle != null) {

                    boolean isReset = bundle.getBoolean("isWorkDone");
                    if (isReset) {

                    } else {
                    }
                }
            }
        }
    }

A DTO is a dumb object - it just holds properties and has getters and setters, but no other logic of any significance (other than maybe a compare() or equals() implementation).

Typically model classes in MVC (assuming .net MVC here) are DTOs, or collections/aggregates of DTOs

If I understand your question correctly, then you probably want a density estimate along with the histogram:

X <- c(rep(65, times=5), rep(25, times=5), rep(35, times=10), rep(45, times=4))
hist(X, prob=TRUE)            # prob=TRUE for probabilities not counts
lines(density(X))             # add a density estimate with defaults
lines(density(X, adjust=2), lty="dotted")   # add another "smoother" density

Edit a long while later:

Here is a slightly more dressed-up version:

X <- c(rep(65, times=5), rep(25, times=5), rep(35, times=10), rep(45, times=4))
hist(X, prob=TRUE, col="grey")# prob=TRUE for probabilities not counts
lines(density(X), col="blue", lwd=2) # add a density estimate with defaults
lines(density(X, adjust=2), lty="dotted", col="darkgreen", lwd=2) 

along with the graph it produces:

The fundamental idea is that if multiple callers ask for resources which are initially indistinguishable, you can give them pointers to the same resource. This function can be maintained until a caller tries to modify its "copy" of the resource, at which point a true private copy is created to prevent the changes becoming visible to everyone else. All of this happens transparently to the callers. The primary advantage is that if a caller never makes any modifications, no private copy need ever be created.

Also here is an application of a common use of COW:

The COW concept is also used in maintenance of instant snapshot on database servers like Microsoft SQL Server 2005. Instant snapshots preserve a static view of a database by storing a pre-modification copy of data when underlaying data are updated. Instant snapshots are used for testing uses or moment-dependent reports and should not be used to replace backups.

Just run this verbatim.

import nltk
nltk.download('tagsets')
nltk.help.upenn_tagset()

nltk.tag._POS_TAGGER won't work. It will give AttributeError: module 'nltk.tag' has no attribute '_POS_TAGGER'. It's not available in NLTK 3 anymore.

There's also workaround doing disjunction of your array, worked for me as other solutions were hard to implement using some old framework.

select * from tableA where id = 1 or id = 2 or id = 3 ...

But for better perfo, I would use Nikolai Nechai's solution with unions, if possible.

You can do a subquery where you first get the IDs of the top 10 ordered by priority and then update the ones that are on that sub query:

UPDATE  messages 
SET status=10 
WHERE ID in (SELECT TOP (10) Id 
             FROM Table 
             WHERE status=0 
             ORDER BY priority DESC);

marks = raw_input('Enter your Obtain marks:')
outof = raw_input('Enter Out of marks:')
marks = int(marks)
outof = int(outof)
per = marks*100/outof
print 'Your Percentage is:'+str(per)

Note : raw_input() function is used to take input from console and its return string formatted value. So we need to convert into integer otherwise it give error of conversion.

Interestingly, I had the same exact issue and for me the problem was that my connection was timing out. To be able to see more details on my connections, I added $mail->SMTPDebug = 4; to my phpmailer (look up how to capture the debug since the default output function is echo).

Here's the result:

SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is ""
SMTP -> get_lines(): $data is ""
SMTP -> get_lines(): timed-out (10 seconds)
SMTP -> FROM SERVER:
SMTP -> ERROR: DATA not accepted from server: 

The default timeout is set to 10 seconds. If your app can support more, add this line to your phpmailer:

$mail->Timeout = 20;

Here is an implementation, character by character. Should work with "(One Two Three)"

public static string ToInitcap(this string str)
{
    if (string.IsNullOrEmpty(str))
        return str;
    char[] charArray = new char[str.Length];
    bool newWord = true;
    for (int i = 0; i < str.Length; ++i)
    {
        Char currentChar = str[i];
        if (Char.IsLetter(currentChar))
        {
            if (newWord)
            {
                newWord = false;
                currentChar = Char.ToUpper(currentChar);
            }
            else
            {
                currentChar = Char.ToLower(currentChar);
            }
        }
        else if (Char.IsWhiteSpace(currentChar))
        {
            newWord = true;
        }
        charArray[i] = currentChar;
    }
    return new string(charArray);
}

DEMO : http://jsfiddle.net/shfj70qp/

//dd/mm/yyyy 

var date = new Date();
var month = date.getMonth();
var day = date.getDate();
var year = date.getFullYear();

console.log(month+"/"+day+"/"+year);

The danger of the second expression comes if the type of byte1 is char. In that case, some implementations can have it signed char, which will result in sign extension when evaluating.

signed char byte1 = 0x80;
signed char byte2 = 0x10;

unsigned short value1 = ((byte2 << 8) | (byte1 & 0xFF));
unsigned short value2 = ((byte2 << 8) | byte1);

printf("value1=%hu %hx\n", value1, value1);
printf("value2=%hu %hx\n", value2, value2);

will print

value1=4224 1080     right
value2=65408 ff80    wrong!!

I tried it on gcc v3.4.6 on Solaris SPARC 64 bit and the result is the same with byte1 and byte2 declared as char.

TL;DR

The masking is to avoid implicit sign extension.

EDIT: I checked, it's the same behaviour in C++.

EDIT2: As requested explanation of sign extension. Sign extension is a consequence of the way C evaluates expressions. There is a rule in C called promotion rule. C will implicitly cast all small types to int before doing the evaluation. Let's see what happens to our expression:

unsigned short value2 = ((byte2 << 8) | byte1);

byte1 is a variable containing bit pattern 0xFF. If char is unsigned that value is interpreted as 255, if it is signed it is -128. When doing the calculation, C will extend the value to an int size (16 or 32 bits generally). This means that if the variable is unsigned and we will keep the value 255, the bit-pattern of that value as int will be 0x000000FF. If it is signed we want the value -128 which bit pattern is 0xFFFFFFFF. The sign was extended to the size of the tempory used to do the calculation. And thus oring the temporary will yield the wrong result.

On x86 assembly it is done with the movsx instruction (movzx for the zero extend). Other CPU's had other instructions for that (6809 had SEX).

In C# you can use the following to replace the single quote with a double quote:

 string sample = "St. Mary's";
 string escapedSample = sample.Replace("'", "''");

And the output will be:

"St. Mary''s"

And, if you are working with Sqlite directly; you can work with object instead of string and catch special things like DBNull:

private static string MySqlEscape(Object usString)
{
    if (usString is DBNull)
    {
        return "";
    }
    string sample = Convert.ToString(usString);
    return sample.Replace("'", "''");
}

Your static method should go from:

public static class SimpleUsing
{
    public static void DoUsing(Action<MyDataContext> action)
    {
        using (MyDataContext db = new MyDataContext())
           action(db);
    }
}

To:

public static class SimpleUsing
{
    public static TResult DoUsing<TResult>(Func<MyDataContext, TResult> action)
    {
        using (MyDataContext db = new MyDataContext())
           return action(db);
    }
}

The algorithm that drives http://www.webqr.com is a JavaScript implementation of https://github.com/LazarSoft/jsqrcode. I haven't tried how reliable it is yet, but that's certainly the easier plug-and-play solution (client- or server-side) out of the two.

Just Open yourApp.jks file with Notepad you will find Keystore & Alias name there!!

What fixed it for me was installing the latest version of node-sass, in this case 4.7.2.

In Rails, the unit folder is meant to hold tests for your models, the functional folder is meant to hold tests for your controllers, and the integration folder is meant to hold tests that involve any number of controllers interacting. Fixtures are a way of organizing test data; they reside in the fixtures folder. The test_helper.rb file holds the default configuration for your tests. u can visit this.

temp2 = temp.substring(i); will always return the empty string "".

Instead, your loop should have the condition i<temp.length(). And temp2 should always be temp.substring(i, i+1);.

Similarly when you're printing out newGuess, you should loop up to newGuess.length but not including. So your condition should be i<newGuess.length.

I exported the following connection from Studio 3T:

mongodb://youn-nosql-grej-test:[email protected]:10255/admin?3t.uriVersion=2&3t.certificatePreference=RootCACert:accept_any&3t.databases=admin&3t.connectionMode=direct&3t.useClientCertPassword=false&3t.connection.name=Grej-Test&readPreference=primary&ssl=true

And I filled it in in the following screens:

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

If you use the matplotlib object-oriented approach, this is a simple task using ax.set_xticklabels() and ax.set_yticklabels():

import matplotlib.pyplot as plt

# Create Figure and Axes instances
fig,ax = plt.subplots(1)

# Make your plot, set your axes labels
ax.plot(sim_1['t'],sim_1['V'],'k')
ax.set_ylabel('V')
ax.set_xlabel('t')

# Turn off tick labels
ax.set_yticklabels([])
ax.set_xticklabels([])

plt.show()

This is a bug in the Android Connector for M2E (m2e-android) that was recently fixed:

https://github.com/rgladwell/m2e-android/commit/2b490f900153cd34fff1cec47fe5aeffabe44d87

This fix has been merged and will be available with the next release. In the meantime you can test the new fix by installing from the following update site:

http://rgladwell.github.com/m2e-android/updates/master/

Static function means that it is associated with class (not a particular instance of class but the class itself) and it can be invoked even when no class instances exist.

Static class means that class contains only static members.

If I understand right, you've made a commit to changed_branch and you want to copy that commit to other_branch? Easy:

git checkout other_branch
git cherry-pick changed_branch

A couple of things wrong here.

1. Do you really want to open and close the connection for every single log entry?

2. Shouldn't you be using SqlCommand instead of SqlDataAdapter?

3. The data adapter (or SqlCommand) needs exactly what the error message tells you it's missing: an active connection. Just because you created a connection object does not magically tell C# that it is the one you want to use (especially if you haven't opened the connection).

I highly recommend a C# / SQL Server tutorial.

The simplest way to install jq and test that it works is through brew and then using the simplest filter that merely formats the JSON

Install

brew is the easiest way to manage packages on a mac:

brew install jq

Need brew? Run the following command:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Failing that: instructions to install and use are on https://brew.sh/

Test

The . filter takes its input and produces it unchanged as output. This is the identity operator. (quote the docs)

echo '{ "name":"John", "age":31, "city":"New York" }' | jq .

The result should appear like so in your terminal:

{
  "name": "John",
  "age": 31,
  "city": "New York"
}

You can also try:

create table new_table as
select * from table1
union
select * from table2

Use the Debug.WriteLine. This will display your message in the Output window immediately. The only restriction is that you must run your test in Debug mode.

[TestMethod]
public void TestMethod1()
{
    Debug.WriteLine("Time {0}", DateTime.Now);
    System.Threading.Thread.Sleep(30000);
    Debug.WriteLine("Time {0}", DateTime.Now);
}

Output

For loops are a bad construct for this.

Using while

var numbers = new List<int>(Enumerable.Range(1, 3));

while (numbers.Count > 0)
{
    numbers.RemoveAt(0);
}

But, if you absolutely must use for

var numbers = new List<int>(Enumerable.Range(1, 3));

for (; numbers.Count > 0;)
{
    numbers.RemoveAt(0);
}

Or, this:

public static class Extensions
{

    public static IList<T> Remove<T>(
        this IList<T> numbers,
        Func<T, bool> predicate)
    {
        numbers.ForEachBackwards(predicate, (n, index) => numbers.RemoveAt(index));
        return numbers;
    }

    public static void ForEachBackwards<T>(
        this IList<T> numbers,
        Func<T, bool> predicate,
        Action<T, int> action)
    {
        for (var i = numbers.Count - 1; i >= 0; i--)
        {
            if (predicate(numbers[i]))
            {
                action(numbers[i], i);
            }
        }
    }
}

Usage:

var numbers = new List<int>(Enumerable.Range(1, 10)).Remove((n) => n > 5);

function splitText(value, index) {
  if (value.length < index) {return value;} 
  return [value.substring(0, index)].concat(splitText(value.substring(index), index));
}
console.log(splitText('this is a testing peace of text',10));
// ["this is a ", "testing pe", "ace of tex", "t"] 

For those who want to split a text into array using the index.

I use >> /dev/null 2>&1 for a silent cronjob. A cronjob will do the job, but not send a report to my email.

As far as I know, don't remove /dev/null. It's useful, especially when you run cPanel, it can be used for throw-away cronjob reports.

Here is an example using css3:

CSS:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    padding: 10px;
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}
.footer {
    position: relative;
    clear:both;
}

HTML:

<div id="wrap">
    body content....
</div>
<footer class="footer">
    footer content....
</footer>

jsfiddle

Update
As @Martin pointed, the ´position: relative´ is not mandatory on the .footer element, the same for clear:both. These properties are only there as an example. So, the minimum css necessary to stick the footer on the bottom should be:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}

Also, there is an excellent article at css-tricks showing different ways to do this: https://css-tricks.com/couple-takes-sticky-footer/

You can use context syntax with this or $(this). This is the same effect as find().

$('select').change(function() {_x000D_
    console.log('Clicked option value => ' + $(this).val());_x000D_
    <!-- undefined console.log('$(this) without explicit :select => ' + $(this).data('id')); -->_x000D_
    <!-- error console.log('this without explicit :select => ' + this.data('id')); -->_x000D_
    console.log(':select & $(this) =>    ' + $(':selected', $(this)).data('id'));_x000D_
    console.log(':select & this =>       ' + $(':selected', this).data('id'));_x000D_
    console.log('option:select & this => ' + $('option:selected', this).data('id'));_x000D_
    console.log('$(this) & find =>       ' + $(this).find(':selected').data('id'));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select>_x000D_
    <option data-id="1">one</option>_x000D_
    <option data-id="2">two</option>_x000D_
    <option data-id="3">three</option>_x000D_
</select>

As a matter of microoptimization, you might opt for find(). If you are more of a code golfer, the context syntax is more brief. It comes down to coding style basically.

Here is a relevant performance comparison.

Its because there is a hidden input with required attribute in the form.

In my case, I had a select box and it is hidden by jquery tokenizer using inline style. If I dont select any token, browser throws the above error on form submission.

So, I fixed it using the below css technique :

  select.download_tag{
     display: block !important;//because otherwise, its throwing error An invalid form control with name='download_tag[0][]' is not focusable.
    //So, instead set opacity
    opacity: 0;
    height: 0px;

 }

Load a page within a page using an iframe. The following should serve as a good starting point.

<body>
  <div>
    <iframe src="page1.html" name="targetframe" allowTransparency="true" scrolling="no" frameborder="0" >
    </iframe>
  </div>

  <br/>

  <div>
    <a href="page2.html" target="targetframe">Link to Page 2</a><br />
    <a href="page3.html" target="targetframe">Link to Page 3</a>
  </div>
</body>

SciPy has the function scipy.special.factorial (formerly scipy.misc.factorial)

>>> import math
>>> import scipy.special
>>> math.factorial(6)
720
>>> scipy.special.factorial(6)
array(720.0)

If you get code behind, use some like this

        MyCustomObject myObject = new MyCustomObject();
        myObject.name='try';
        //OBJECT -> JSON
        var javaScriptSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        string myObjectJson = javaScriptSerializer.Serialize(myObject);
        //return JSON   
        Response.Clear();     
        Response.ContentType = "application/json; charset=utf-8";
        Response.Write(myObjectJson );
        Response.End();

So you return a json object serialized with all attributes of MyCustomObject.

Another place this error can happen in is assigning a value that has a comma outside of a string. For example:

SET totalvalue = (IFNULL(i.subtotal,0) + IFNULL(i.tax,0),0)

In case you want to do it yourself..

List<Integer> commons = new ArrayList<Integer>();

for (Integer igr : group1) {
    if (group2.contains(igr)) {
        commons.add(igr);
    }
}

System.out.println("Common elements are :: -");
for (Integer igr : commons) {
    System.out.println(" "+igr);
}
