Programs & Examples On #Statechart

In my experience using the 'switch' statement is the standard way to handle multiple possible states. Although I am surpirsed that you are passing in a transition value to the per-state processing. I thought the whole point of a state machine was that each state performed a single action. Then the next action/input determines which new state to transition into. So I would have expected each state processing function to immediately perform whatever is fixed for entering state and then afterwards decide if transition is needed to another state.

I'm using IIS Express, rather than IIS.

The problem was in the applicationhost.config file located in: {solution_folder}\.vs\config\applicationhost.config.

One of the application pool entries had a managedRuntimeVersion value of "v2.0". I changed it to "v4.0", and it worked properly.

I'm fairly sure the root cause was one of the NuGet packages I had installed recently.

    <system.applicationHost>
       <applicationPools>
          <add name="BadAppPool1" managedRuntimeVersion="v2.0" managedPipelineMode="Integrated" CLRConfigFile="%IIS_USER_HOME%\config\aspnet.config" autoStart="true" />
       </applicationPools>
    </system.applicationHost>

A closure is a block of code that can be referenced (and passed around) with access to the variables of the enclosing scope.

Since Java 1.1, anonymous inner class have provided this facility in a highly verbose manner. They also have a restriction of only being able to use final (and definitely assigned) local variables. (Note, even non-final local variables are in scope, but cannot be used.)

Java SE 8 is intended to have a more concise version of this for single-method interfaces*, called "lambdas". Lambdas have much the same restrictions as anonymous inner classes, although some details vary randomly.

Lambdas are being developed under Project Lambda and JSR 335.

*Originally the design was more flexible allowing Single Abstract Methods (SAM) types. Unfortunately the new design is less flexible, but does attempt to justify allowing implementation within interfaces.

you don't need to create a hidden field for all checkboxes just copy my code. it will change the value of checkbox if not checked the value will assign 0 and if checkbox checked then assign value into 1

$("form").submit(function () {

    var this_master = $(this);

    this_master.find('input[type="checkbox"]').each( function () {
        var checkbox_this = $(this);


        if( checkbox_this.is(":checked") == true ) {
            checkbox_this.attr('value','1');
        } else {
            checkbox_this.prop('checked',true);
            //DONT' ITS JUST CHECK THE CHECKBOX TO SUBMIT FORM DATA    
            checkbox_this.attr('value','0');
        }
    })
})

See whether the below query will help

SELECT *
FROM MY_TABLE
WHERE CHARINDEX('.',MY_FIELD) = 0 AND CHARINDEX(',',MY_FIELD) = 0       
AND ISNUMERIC(MY_FIELD) = 1 AND CONVERT(FLOAT,MY_FIELD) / 2147483647 <= 1

you should check the radiobutton in the radiogroup like this:

radiogroup.check(IdOfYourButton)

Of course you first have to set an Id to your radiobuttons

EDIT: i forgot, radioButton.getId() works as well, thx Ramesh

EDIT2:

android:checkedButton="@+id/my_radiobtn"

works in radiogroup xml

If you want insert into specify column:

INSERT INTO table (time)
(SELECT time FROM 
    dblink('dbname=dbtest', 'SELECT time FROM tblB') AS t(time integer) 
    WHERE time > 1000
);

Use this in your conda prompt:

python -m pip install xgboost

The iframe always keeps the parent page, you should use this to detect in which page you are in the iframe:

Html code:

<iframe id="iframe" frameborder="0" scrolling="no" onload="resizeIframe(this)" width="100%" src="www.google.com"></iframe>

Js:

    function resizeIframe(obj) {
        alert(obj.contentWindow.location.pathname);
    }

It is stored in the heap referenced by the class definition. If you think about it, it has nothing to do with stack because there is no scope.

Use ALTER:

ALTER TABLE `tbl_Country` DROP COLUMN `column_name`;

Now in the year of 2020. fix this issue by my side with mac: pip install jupyterlab instead pip install jupyter. there will be an warning before successfully installed keywords: enter image description here

you can see the path with jupyterlab then you just need to start jupyter notebook by following in path:

jupyter-lab

notebook will automatic loaded by your default browser.

Just install php5-cgi in debian

sudo apt-get install php5-cgi

in Centos

sudo yum install php5-cgi

I have created the batch file and put it to the Cygwin's /bin directory. This script was developed so it allows to install/uninstall the registry entries for opening selected folders and drives in Cygwin. For details see the link http://with-love-from-siberia.blogspot.com/2013/12/cygwin-here.html.

update: This solution does the same as early suggestions but all manipulations with Windows Registry are hidden within the script.

Perform the command to install

cyghere.bat /install

Perform the command to uninstall

cyghere.bat /uninstall

This is not a direct answer to the question. Rather it answers this question: "How do I choose a specific function output from many possible options?".

If you are able to write the function (ie, it is not in a library you cannot modify), then add an input argument that indicates what you want out of the function. Make it a named argument with a default value so in the "common case" you don't even have to specify it.

    def fancy_function( arg1, arg2, return_type=1 ):
        ret_val = None
        if( 1 == return_type ):
            ret_val = arg1 + arg2
        elif( 2 == return_type ):
            ret_val = [ arg1, arg2, arg1 * arg2 ]
        else:
            ret_val = ( arg1, arg2, arg1 + arg2, arg1 * arg2 ) 
        return( ret_val )

This method gives the function "advanced warning" regarding the desired output. Consequently it can skip unneeded processing and only do the work necessary to get your desired output. Also because Python does dynamic typing, the return type can change. Notice how the example returns a scalar, a list or a tuple... whatever you like!

command > file >&1

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

glob.glob or os.listdir will do it.

If you want to avoid those IDesignTimeDbContextFactory thing: Just make sure that you don't use any Seed method in your startup. I was using a static seed method in my startup and it was causing this error for me.

You can use something like the following:

DECLARE db_cursor CURSOR FOR  
SELECT name 
FROM master.dbo.sysdatabases 
WHERE name IN ("TB2","TB1")  -- use these databases

OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @name   


WHILE @@FETCH_STATUS = 0   
BEGIN   

       DELETE FROM @name WHERE PersonID ='2'

       FETCH NEXT FROM db_cursor INTO @name   
END  

Also, linear congruential PRNGs tend to produce more randomness on the higher bits that on the lower bits, so to cap the result don't use modulo, but instead use something like:

j = 1 + (int) (10.0 * (rand() / (RAND_MAX + 1.0)));

(This one is from "Numerical Recipes in C", ch.7)

PHP has some nice built in functions for getting geographic location. Maybe have a look here: http://php.net/manual/en/ref.geoip.php

According to php manual, "This extension requires the GeoIP C library version 1.4.0 or higher to be installed. You can grab the latest version from » http://www.maxmind.com/app/c and compile it yourself."

Non-blocking: This function won't wait while on the stack.

Asynchronous: Work may continue on behalf of the function call after that call has left the stack

I believe that the "problem" with all of the above is that it depends upon a certain implementation convention either of docker itself or its implementation and how that interacts with cgroups and /proc, and not via a committed, public, API, protocol or convention as part of the OCI specs.

Hence these solutions are "brittle" and likely to break when least expected when implementations change, or conventions are overridden by user configuration.

container and image ids should be injected into the r/t environment by the component that initiated the container instance, if for no other reason than to permit code running therein to use that information to uniquely identify themselves for logging/tracing etc...

just my $0.02, YMMV...

For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.

For enabling headers in Ubuntu:

sudo a2enmod headers

For php server to accept request from different origin use:

Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

The web host is not really playing foul. It's not strictly according to the rules - but compared with some some of the amazing inventions intended to prevent spam, its not a particularly bad one.

If you really do want to send mail from '@gmail.com' why not just use the gmail SMTP service? If you can't reconfigure the server where PHP is running, then there are lots of email wrapper tools out there which allow you to specify a custom SMTP relay phpmailer springs to mind.

C.

Yes, you will need the mysql c++ connector library. Read on below, where I explain how to get the example given by mysql developers to work.

Note(and solution): IDE: I tried using Visual Studio 2010, but just a few sconds ago got this all to work, it seems like I missed it in the manual, but it suggests to use Visual Studio 2008. I downloaded and installed VS2008 Express for c++, followed the steps in chapter 5 of manual and errors are gone! It works. I'm happy, problem solved. Except for the one on how to get it to work on newer versions of visual studio. You should try the mysql for visual studio addon which maybe will get vs2010 or higher to connect successfully. It can be downloaded from mysql website

Whilst trying to get the example mentioned above to work, I find myself here from difficulties due to changes to the mysql dev website. I apologise for writing this as an answer, since I can't comment yet, and will edit this as I discover what to do and find the solution, so that future developers can be helped.(Since this has gotten so big it wouldn't have fitted as a comment anyways, haha)

@hd1 link to "an example" no longer works. Following the link, one will end up at the page which gives you link to the main manual. The main manual is a good reference, but seems to be quite old and outdated, and difficult for new developers, since we have no experience especially if we missing a certain file, and then what to add.

@hd1's link has moved, and can be found with a quick search by removing the url components, keeping just the article name, here it is anyways: http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-examples-complete-example-1.html

Getting 7.5 MySQL Connector/C++ Complete Example 1 to work

Downloads:

-Get the mysql c++ connector, even though it is bigger choose the installer package, not the zip.

-Get the boost libraries from boost.org, since boost is used in connection.h and mysql_connection.h from the mysql c++ connector

Now proceed:

-Install the connector to your c drive, then go to your mysql server install folder/lib and copy all libmysql files, and paste in your connector install folder/lib/opt

-Extract the boost library to your c drive

Next:

It is alright to copy the code as it is from the example(linked above, and ofcourse into a new c++ project). You will notice errors:

-First: change

cout << "(" << __FUNCTION__ << ") on line " »
 << __LINE__ << endl;

to

cout << "(" << __FUNCTION__ << ") on line " << __LINE__ << endl;

Not sure what that tiny double arrow is for, but I don't think it is part of c++

-Second: Fix other errors of them by reading Chapter 5 of the sql manual, note my paragraph regarding chapter 5 below

[Note 1]: Chapter 5 Building MySQL Connector/C++ Windows Applications with Microsoft Visual Studio If you follow this chapter, using latest c++ connecter, you will likely see that what is in your connector folder and what is shown in the images are quite different. Whether you look in the mysql server installation include and lib folders or in the mysql c++ connector folders' include and lib folders, it will not match perfectly unless they update the manual, or you had a magic download, but for me they don't match with a connector download initiated March 2014.

Just follow that chapter 5,

-But for c/c++, General, Additional Include Directories include the "include" folder from the connector you installed, not server install folder

-While doing the above, also include your boost folder see note 2 below

-And for the Linker, General.. etc use the opt folder from connector/lib/opt

*[Note 2]*A second include needs to happen, you need to include from the boost library variant.hpp, this is done the same as above, add the main folder you extracted from the boost zip download, not boost or lib or the subfolder "variant" found in boostmainfolder/boost.. Just the main folder as the second include

Next:

What is next I think is the Static Build, well it is what I did anyways. Follow it.

Then build/compile. LNK errors show up(Edit: Gone after changing ide to visual studio 2008). I think it is because I should build connector myself(if you do this in visual studio 2010 then link errors should disappear), but been working on trying to get this to work since Thursday, will see if I have the motivation to see this through after a good night sleep(and did and now finished :) ).

The return type must be the same as, or a subtype of, the return type declared in the original overridden method in the superclass.

There is an extension for that, but I have no usage experience yet:

http://ipython.scipy.org/ipython/ipython/attachment/ticket/154/ipy_autoreload.py

Hi i tried this it is working.

$("#change_align").css({"margin-top":"-39px","margin-right":"0px","margin-bottom":"0px","margin-left":"719px"});

Setting the Hadoop_Home environment variable in system properties didn't work for me. But this did:

• Set the Hadoop_Home in the Eclipse Run Configurations environment tab.
• Follow the 'Windows Environment Setup' from here

In my opinion the simpliest way to get column number is:
Sub Sample() ColName = ActiveCell.Column MsgBox ColName End Sub

Decide a width and check how many characters one line could hold, and then for each key pressed you call a function that looks something like:

function changeHeight()
{
var chars_per_row = 100;
var pixles_per_row = 16;
this.style.height = Math.round((this.value.length / chars_per_row) * pixles_per_row) + 'px';
}

Havn't tested the code.

While waiting for read() or write() to/from a file descriptor return, the process will be put in a special kind of sleep, known as "D" or "Disk Sleep". This is special, because the process can not be killed or interrupted while in such a state. A process waiting for a return from ioctl() would also be put to sleep in this manner.

An exception to this is when a file (such as a terminal or other character device) is opened in O_NONBLOCK mode, passed when its assumed that a device (such as a modem) will need time to initialize. However, you indicated block devices in your question. Also, I have never tried an ioctl() that is likely to block on a fd opened in non blocking mode (at least not knowingly).

How another process is chosen depends entirely on the scheduler you are using, as well as what other processes might have done to modify their weights within that scheduler.

Some user space programs under certain circumstances have been known to remain in this state forever, until rebooted. These are typically grouped in with other "zombies", but the term would not be correct as they are not technically defunct.

htaccess files affect the directory they are placed in and all sub-directories, that is an htaccess file located in your root directory (yoursite.com) would affect yoursite.com/content, yoursite.com/content/contents, etc.

MySQL uses CONCAT() to concatenate strings

SELECT * FROM tableOne 
LEFT JOIN tableTwo
ON tableTwo.query = CONCAT('category_id=', tableOne.category_id)

Why don't you just do

for s in l :
    print s
print "done"

?

xhr.getResponseHeader('Set-Cookie');

It won't work for me.

I use this

function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i=0; i<ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1);
        if (c.indexOf(name) != -1) return c.substring(name.length,c.length);
    }
    return "";
} 

success: function(output, status, xhr) {
    alert(getCookie("MyCookie"));
},

Use JSON.stringify() and JSON.parse() as suggested by no! This prevents the maybe rare but possible problem of a member name which includes the delimiter (e.g. member name three|||bars).

This is what I did:

Basically, think of the detached HEAD as a new branch, without name. You can commit into this branch just like any other branch. Once you are done committing, you want to push it to the remote.

So the first thing you need to do is give this detached HEAD a name. You can easily do it like, while being on this detached HEAD:

git checkout -b some-new-branch

Now you can push it to remote like any other branch.

In my case, I also wanted to fast-forward this branch to master along with the commits I made in the detached HEAD (now some-new-branch). All I did was

git checkout master

git pull # To make sure my local copy of master is up to date

git checkout some-new-branch

git merge master // This added current state of master to my changes

Of course, I merged it later to master.

That's about it.

This work for me

from flask import Flask
from flask import Response

app = Flask(__name__)

@app.route("/")
def home():
    return Response(headers={'Access-Control-Allow-Origin':'*'})

if __name__ == "__main__":
    app.run()

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

One more thing to check is that you have spelled the named instance correctly!

After that, i called it in Kotlin as follows :-

    val builder = AlertDialog.Builder(mContext)
    val viewGroup: ViewGroup = findViewById(android.R.id.content)
    val dialogView: View = 
    LayoutInflater.from(mContext).inflate(R.layout.subdomain_bottom_sheet, 
    viewGroup, false)
    val alertDialog: AlertDialog = builder.create()
    alertDialog.setView(dialogView,0,0,0,0)
    alertDialog.show()
    val windowParam = WindowManager.LayoutParams()
    windowParam.copyFrom(alertDialog.window!!.attributes)
    windowParam.width = AppConstant.getDisplayMetricsWidth(mContext) - 100
    windowParam.height = WindowManager.LayoutParams.WRAP_CONTENT
    windowParam.gravity = Gravity.CENTER
    alertDialog.window!!.attributes = windowParam
    
   
    alertDialog.window!!.setBackgroundDrawable
    (ColorDrawable(Color.TRANSPARENT))

Where last line is very important. Missing that would cause a color(mostly white) to show behind the corners.

Just an important note. If you have HTML comment and your uncomment doesn't work
(Maybe it's a PHP file), so don't mark all the comment but just put your cursor at the end or at the beginning of the comment (before ) and try again (Ctrl+/).

Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.

SSLContextBuilder sslcontextbuilder = SSLContexts.custom();

sslcontextbuilder.loadTrustMaterial(
            new File("C:\\path to\\truststore.jks"), //path to jks file
            "password".toCharArray(), //enters in the truststore password for use
            new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
            );

SSLContext sslcontext = sslcontextbuilder.build(); //load trust store

SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory 



try { 
        HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert

        System.out.println("Executing request " + httpget.getRequestLine());

        CloseableHttpResponse response = httpclient.execute(httpget);
        try {
            HttpEntity entity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());

            EntityUtils.consume(entity);
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

Either attribute can be applied to View's (visual control) horizontal or vertical size. It's used to set a View or Layouts size based on either it's contents or the size of it's parent layout rather than explicitly specifying a dimension.

fill_parent (deprecated and renamed MATCH_PARENT in API Level 8 and higher)

Setting the layout of a widget to fill_parent will force it to expand to take up as much space as is available within the layout element it's been placed in. It's roughly equivalent of setting the dockstyle of a Windows Form Control to Fill.

Setting a top level layout or control to fill_parent will force it to take up the whole screen.

wrap_content

Setting a View's size to wrap_content will force it to expand only far enough to contain the values (or child controls) it contains. For controls -- like text boxes (TextView) or images (ImageView) -- this will wrap the text or image being shown. For layout elements it will resize the layout to fit the controls / layouts added as its children.

It's roughly the equivalent of setting a Windows Form Control's Autosize property to True.

Online Documentation

There's some details in the Android code documentation here.

As I'm not very fond of using the new keyword or other constructor like calls on singletons, I would prefer to use a static getter called inst for example:

// the singleton class
class Dao {
    // singleton boilerplate
        Dao._internal() {}
        static final Dao _singleton = new Dao._internal();
        static get inst => _singleton;

    // business logic
        void greet() => print("Hello from singleton");
}

example usage:

Dao.inst.greet();       // call a method

// Dao x = new Dao();   // compiler error: Method not found: 'Dao'

// verify that there only exists one and only one instance
assert(identical(Dao.inst, Dao.inst));

Create an object holding following properties with an appropriate name.

1. message
2. timestamp
3. count
4. version

and use this as a value in your map.

Also consider overriding the equals() and hashCode() method accordingly if you do not want object equality to be used for comparison (e.g. when inserting values into your map).

Based on the solution from bluefeet here is a stored procedure that uses dynamic sql to generate the transposed table. It requires that all the fields are numeric except for the transposed column (the column that will be the header in the resulting table):

I was looking for a similar thing. Chrome only... In my case the wrapper div needed to know if the input field was autofilled. So I could give it extra css just like Chrome does on the input field when it autofills it. By looking at all the answers above my combined solution was the following:

/* 
 * make a function to use it in multiple places
 */
var checkAutoFill = function(){
    $('input:-webkit-autofill').each(function(){
        $(this).closest('.input-wrapper').addClass('autofilled');
    });
}

/* 
 * Put it on the 'input' event 
 * (happens on every change in an input field)
 */
$('html').on('input', function() {
    $('.input-wrapper').removeClass('autofilled');
    checkAutoFill();
});

/*
 * trigger it also inside a timeOut event 
 * (happens after chrome auto-filled fields on page-load)
 */
setTimeout(function(){ 
    checkAutoFill();
}, 0);

The html for this to work would be

<div class="input-wrapper">
    <input type="text" name="firstname">
</div>

Incorrect:

  empId: 123

Um, anybody heard of Zend Guard, which does exactly what this person is asking. It encodes/obfuscates PHP code into "machine code".

In addition to what @ckal suggested, it is critical to give each renamed Configuration.cs its own namespace. If you do not, EF will attempt to apply migrations to the wrong context.

Here are the specific steps that work well for me.

If Migrations are messed up and you want to create a new "baseline":

1. Delete any existing .cs files in the Migrations folder
2. In SSMS, delete the __MigrationHistory system table.

Creating the initial migration:

1. In Package Manager Console:

   Enable-Migrations -EnableAutomaticMigrations -ContextTypeName
   NamespaceOfContext.ContextA -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextA
   

2. In Solution Explorer: Rename Migrations.Configuration.cs to Migrations.ConfigurationA.cs. This should automatically rename the constructor if using Visual Studio. Make sure it does. Edit ConfigurationA.cs: Change the namespace to NamespaceOfContext.Migrations.MigrationsA

3. Enable-Migrations -EnableAutomaticMigrations -ContextTypeName
   NamespaceOfContext.ContextB -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextB
   

4. In Solution Explorer: Rename Migrations.Configuration.cs to Migrations.ConfigurationB.cs. Again, make sure the constructor is also renamed appropriately. Edit ConfigurationB.cs: Change the namespace to NamespaceOfContext.Migrations.MigrationsB

5. add-migration InitialBSchema -IgnoreChanges -ConfigurationTypeName
   ConfigurationB -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextB 
   

6. Update-Database -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

7. add-migration InitialSurveySchema -IgnoreChanges -ConfigurationTypeName
   ConfigurationA -ProjectName ProjectContextIsInIfNotMainOne -StartupProjectName
   NameOfMainProject  -ConnectionStringName ContextA 
   

8. Update-Database -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

Steps to create migration scripts in Package Manager Console:

1. Run command

   Add-Migration MYMIGRATION -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

   or -

   Add-Migration MYMIGRATION -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

   It is OK to re-run this command until changes are applied to the DB.

2. Either run the scripts against the desired local database, or run Update-Database without -Script to apply locally:

   Update-Database -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

   or -

   Update-Database -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

I have found a 2nd solution.

1. Press "Debug" button in the popup.
2. Press Ctrl+Pause|Break twice.
3. Hit the play button to continue.
4. Save the file after completion.

Hope this helps someone.

your model just have getter and setter in androidX. else not find your model in view and show this bug

public class User {

String name;

public String getName() {
    return name;
}
public User(String name) {
    this.name = name;
}

}

A sort-of-canonical definition is "when two threads access the same location in memory at the same time, and at least one of the accesses is a write." In the situation the "reader" thread may get the old value or the new value, depending on which thread "wins the race." This is not always a bug—in fact, some really hairy low-level algorithms do this on purpose—but it should generally be avoided. @Steve Gury give's a good example of when it might be a problem.

msgbox ("Message goes here",0+16,"Title goes here")

if the user is supposed to make a decision the variable can be added like this.

variable=msgbox ("Message goes here",0+16,"Title goes here")

The numbers in the middle vary what the message box looks like. Here is the list

0 - ok button only

1 - ok and cancel

2 - abort, retry and ignore

3 - yes no and cancel

4 - yes and no

5 - retry and cancel

TO CHANGE THE SYMBOL (RIGHT NUMBER)

16 - critical message icon

32 - warning icon

48 - warning message

64 - info message

DEFAULT BUTTON

0 = vbDefaultButton1 - First button is default

256 = vbDefaultButton2 - Second button is default

512 = vbDefaultButton3 - Third button is default

768 = vbDefaultButton4 - Fourth button is default

SYSTEM MODAL

4096 = System modal, alert will be on top of all applications

Note: There are some extra numbers. You just have to add them to the numbers already there like

msgbox("Hello World", 0+16+0+4096)

I would use a color wheel and given a random position you could add the golden angle (137,5 degrees)

http://en.wikipedia.org/wiki/Golden_angle

in order to get different colours each time that do not overlap.

Adjusting the brightness for the color wheel you could get also different bright/dark color combinations.

I've found this blog post that explains really well the problem and the solution using the golden ratio.

http://martin.ankerl.com/2009/12/09/how-to-create-random-colors-programmatically/

UPDATE: I've just found this other approach:

It's called RYB(red, yellow, blue) method and it's described in this paper:

http://threekings.tk/mirror/ryb_TR.pdf

as "Paint Inspired Color Compositing".

The algorithm generates the colors and each new color is chosen to maximize its euclidian distance to the previously selected ones.

Here you can find a a good implementation in javascript:

http://afriggeri.github.com/RYB/

UPDATE 2:

The Sciences Po Medialb have just released a tool called "I want Hue" that generate color palettes for data scientists. Using different color spaces and generating the palettes by using k-means clustering or force vectors ( repulsion graphs) The results from those methods are very good, they show the theory and an implementation in their web page.

http://tools.medialab.sciences-po.fr/iwanthue/index.php

With accordance with the answer by daveraja, here is a bash script which will solve the purpose.

Consider a situation if you are using C-shell and you want to execute a command without leaving the C-shell context/window as follows,

Command to be executed: Search exact word 'Testing' in current directory recursively only in *.h, *.c files

grep -nrs --color -w --include="*.{h,c}" Testing ./

Solution 1: Enter into bash from C-shell and execute the command

bash
grep -nrs --color -w --include="*.{h,c}" Testing ./
exit

Solution 2: Write the intended command into a text file and execute it using bash

echo 'grep -nrs --color -w --include="*.{h,c}" Testing ./' > tmp_file.txt
bash tmp_file.txt

Solution 3: Run command on the same line using bash

bash -c 'grep -nrs --color -w --include="*.{h,c}" Testing ./'

Solution 4: Create a sciprt (one-time) and use it for all future commands

alias ebash './execute_command_on_bash.sh'
ebash grep -nrs --color -w --include="*.{h,c}" Testing ./

The script is as follows,

#!/bin/bash

  exit 0
else
  echo "Something is wrong"
  echo "Last command in your tmp file should be removing itself"

 select convert_tz(now(),@@session.time_zone,'+05:30')

replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994

to format into desired time format, eg:

 select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p') 

you will get similar to this -> Dec 17 2014 10:39:56 AM

In NumPy it is quite simple

import numpy as np
P=2.45
S=[22, 33, 45.6, 21.6, 51.8]
SP = P*np.array(S)

I recommend taking a look at the NumPy tutorial for an explanation of the full capabilities of NumPy's arrays:

https://scipy.github.io/old-wiki/pages/Tentative_NumPy_Tutorial

I/O bound refers to a condition in which the time it takes to complete a computation is determined principally by the period spent waiting for input/output operations to be completed.

This is the opposite of a task being CPU bound. This circumstance arises when the rate at which data is requested is slower than the rate it is consumed or, in other words, more time is spent requesting data than processing it.

I used a form with a single submit button. Point the "action" attribute to the ID of the element that needs to be navigated to. Worked for me with just "#top" without needing to define an ID in my stylesheet:

<form action="#top">
    <button type="submit">Back to Top</button>
</form>

Maybe a couple extra lines than is desirable but it's a button, at least. I find this the most concise and descriptive way to go about it.

aca definis los anchos

 float[] anchoDeColumnas= new float[] {10f, 20f, 30f, 10f};

aca se los insertas a la tabla que tiene las columnas

table.setWidths(anchoDeColumnas);

In the picture you can see. In the set script options, choose the last option: Types of data to script you click at the right side and you choose what you want. This is the option you should choose to export a schema and data

Here is some simple pseudo code, push is O(n), pop / peek is O(1):

Qpush = Qinstance()
Qpop = Qinstance()

def stack.push(item):
    Qpush.add(item)
    while Qpop.peek() != null: //transfer Qpop into Qpush
        Qpush.add(Qpop.remove()) 
    swap = Qpush
    Qpush = Qpop
    Qpop = swap

def stack.pop():
    return Qpop.remove()

def stack.peek():
    return Qpop.peek()

I like Eclipse + PyDev and/or eric, myself. The new version of PyDev has some pretty awesome code completion support.

Since I only use Eclipse for PyDev, I use a slim install of just the Platform Runtime Binary + PyDev + Subclipse.

You should have to use Date.ParseExact or Date.TryParseExact with correct format string.

 Dim edate = "10/12/2009"
 Dim expenddt As Date = Date.ParseExact(edate, "dd/MM/yyyy", 
            System.Globalization.DateTimeFormatInfo.InvariantInfo)

OR

 Dim format() = {"dd/MM/yyyy", "d/M/yyyy", "dd-MM-yyyy"}
 Dim expenddt As Date = Date.ParseExact(edate, format,  
     System.Globalization.DateTimeFormatInfo.InvariantInfo, 
     Globalization.DateTimeStyles.None)

OR

Dim format() = {"dd/MM/yyyy", "d/M/yyyy", "dd-MM-yyyy"}
Dim expenddt As Date
Date.TryParseExact(edate, format, 
    System.Globalization.DateTimeFormatInfo.InvariantInfo, 
    Globalization.DateTimeStyles.None, expenddt)

I just ran into the same issue for Ubuntu 13.04. These commands removed Postgres 9.1:

sudo apt-get purge postgresql
sudo apt-get autoremove postgresql

It occurs to me that perhaps only the second command is necessary, but from there I was able to install Postgres 9.2 (sudo apt-get install postgresql-9.2).

An alternative version of the ordinal function could be as follows:

function toCardinal(num) {
    var ones = num % 10;
    var tens = num % 100;

    if (tens < 11 || tens > 13) {
        switch (ones) {
            case 1:
                return num + "st";
            case 2:
                return num + "nd";
            case 3:
                return num + "rd";
        }
    }

    return num + "th";
}

The variables are named more explicitly, uses camel case convention, and might be faster.

This is how I got client certification working and checking that a specific Root CA had issued it as well as it being a specific certificate.

First I edited <src>\.vs\config\applicationhost.config and made this change: <section name="access" overrideModeDefault="Allow" />

This allows me to edit <system.webServer> in web.config and add the following lines which will require a client certification in IIS Express. Note: I edited this for development purposes, do not allow overrides in production.

For production follow a guide like this to set up the IIS:

https://medium.com/@hafizmohammedg/configuring-client-certificates-on-iis-95aef4174ddb

web.config:

<security>
  <access sslFlags="Ssl,SslNegotiateCert,SslRequireCert" />
</security>

API Controller:

[RequireSpecificCert]
public class ValuesController : ApiController
{
    // GET api/values
    public IHttpActionResult Get()
    {
        return Ok("It works!");
    }
}

Attribute:

public class RequireSpecificCertAttribute : AuthorizationFilterAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        if (actionContext.Request.RequestUri.Scheme != Uri.UriSchemeHttps)
        {
            actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
            {
                ReasonPhrase = "HTTPS Required"
            };
        }
        else
        {
            X509Certificate2 cert = actionContext.Request.GetClientCertificate();
            if (cert == null)
            {
                actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                {
                    ReasonPhrase = "Client Certificate Required"
                };

            }
            else
            {
                X509Chain chain = new X509Chain();

                //Needed because the error "The revocation function was unable to check revocation for the certificate" happened to me otherwise
                chain.ChainPolicy = new X509ChainPolicy()
                {
                    RevocationMode = X509RevocationMode.NoCheck,
                };
                try
                {
                    var chainBuilt = chain.Build(cert);
                    Debug.WriteLine(string.Format("Chain building status: {0}", chainBuilt));

                    var validCert = CheckCertificate(chain, cert);

                    if (chainBuilt == false || validCert == false)
                    {
                        actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                        {
                            ReasonPhrase = "Client Certificate not valid"
                        };
                        foreach (X509ChainStatus chainStatus in chain.ChainStatus)
                        {
                            Debug.WriteLine(string.Format("Chain error: {0} {1}", chainStatus.Status, chainStatus.StatusInformation));
                        }
                    }
                }
                catch (Exception ex)
                {
                    Debug.WriteLine(ex.ToString());
                }
            }

            base.OnAuthorization(actionContext);
        }
    }

    private bool CheckCertificate(X509Chain chain, X509Certificate2 cert)
    {
        var rootThumbprint = WebConfigurationManager.AppSettings["rootThumbprint"].ToUpper().Replace(" ", string.Empty);

        var clientThumbprint = WebConfigurationManager.AppSettings["clientThumbprint"].ToUpper().Replace(" ", string.Empty);

        //Check that the certificate have been issued by a specific Root Certificate
        var validRoot = chain.ChainElements.Cast<X509ChainElement>().Any(x => x.Certificate.Thumbprint.Equals(rootThumbprint, StringComparison.InvariantCultureIgnoreCase));

        //Check that the certificate thumbprint matches our expected thumbprint
        var validCert = cert.Thumbprint.Equals(clientThumbprint, StringComparison.InvariantCultureIgnoreCase);

        return validRoot && validCert;
    }
}

Can then call the API with client certification like this, tested from another web project.

[RoutePrefix("api/certificatetest")]
public class CertificateTestController : ApiController
{

    public IHttpActionResult Get()
    {
        var handler = new WebRequestHandler();
        handler.ClientCertificateOptions = ClientCertificateOption.Manual;
        handler.ClientCertificates.Add(GetClientCert());
        handler.UseProxy = false;
        var client = new HttpClient(handler);
        var result = client.GetAsync("https://localhost:44331/api/values").GetAwaiter().GetResult();
        var resultString = result.Content.ReadAsStringAsync().GetAwaiter().GetResult();
        return Ok(resultString);
    }

    private static X509Certificate GetClientCert()
    {
        X509Store store = null;
        try
        {
            store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadOnly);

            var certificateSerialNumber= "?81 c6 62 0a 73 c7 b1 aa 41 06 a3 ce 62 83 ae 25".ToUpper().Replace(" ", string.Empty);

            //Does not work for some reason, could be culture related
            //var certs = store.Certificates.Find(X509FindType.FindBySerialNumber, certificateSerialNumber, true);

            //if (certs.Count == 1)
            //{
            //    var cert = certs[0];
            //    return cert;
            //}

            var cert = store.Certificates.Cast<X509Certificate>().FirstOrDefault(x => x.GetSerialNumberString().Equals(certificateSerialNumber, StringComparison.InvariantCultureIgnoreCase));

            return cert;
        }
        finally
        {
            store?.Close();
        }
    }
}

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:

12 << 2

48

Actual binary value of 12 is "00 1100" when we execute the above statement Left shift ( 2 places shifted left) returns the value 48 its binary value is "11 0000".

48 >> 2

12

The binary value of 48 is "11 0000", after executing above statement Right shift ( 2 places shifted right) returns the value 12 its binary value is "00 1100".

See this section on the MediaWiki docs

These are the key parameters.

prop=revisions&rvprop=content&rvsection=0

rvsection = 0 specifies to only return the lead section.

See this example.

http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&rvsection=0&titles=pizza

To get the HTML, you can use similarly use action=parse http://en.wikipedia.org/w/api.php?action=parse&section=0&prop=text&page=pizza

Note, that you'll have to strip out any templates or infoboxes.

another way to do this is by going through the intermediate table. I'd express this within the Django ORM like this:

UserZone = User.zones.through

# for a single zone
users_in_zone = User.objects.filter(
  id__in=UserZone.objects.filter(zone=zone1).values('user'))

# for multiple zones
users_in_zones = User.objects.filter(
  id__in=UserZone.objects.filter(zone__in=[zone1, zone2, zone3]).values('user'))

it would be nice if it didn't need the .values('user') specified, but Django (version 3.0.7) seems to need it.

the above code will end up generating SQL that looks something like:

SELECT * FROM users WHERE id IN (SELECT user_id FROM userzones WHERE zone_id IN (1,2,3))

which is nice because it doesn't have any intermediate joins that could cause duplicate users to be returned

The difference between starting an Activity from a Fragment and an Activity is how you get the context, because in both cases it has to be an activity.

From an activity: The context is the current activity (this)

Intent intent = new Intent(this, NewActivity.class);
startActivity(intent);

From a fragment: The context is the parent activity (getActivity()). Notice, that the fragment itself can start the activity via startActivity(), this is not necessary to be done from the activity.

Intent intent = new Intent(getActivity(), NewActivity.class);
startActivity(intent);

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

Use sleep like so:

sleep 2

That'll sleep for 2 seconds.

Be careful to give an argument. If you just run sleep, the process will sleep forever. (This is useful when you want a thread to sleep until it's woken.)

If anybody is looking for a quick and easy way to add a gradient to a view:

extension UIView {
    
    func addGradient(colors: [UIColor] = [.blue, .white], locations: [NSNumber] = [0, 2], startPoint: CGPoint = CGPoint(x: 0.0, y: 1.0), endPoint: CGPoint = CGPoint(x: 1.0, y: 1.0), type: CAGradientLayerType = .axial){
        
        let gradient = CAGradientLayer()
        
        gradient.frame.size = self.frame.size
        gradient.frame.origin = CGPoint(x: 0.0, y: 0.0)

        // Iterates through the colors array and casts the individual elements to cgColor
        // Alternatively, one could use a CGColor Array in the first place or do this cast in a for-loop
        gradient.colors = colors.map{ $0.cgColor }
        
        gradient.locations = locations
        gradient.startPoint = startPoint
        gradient.endPoint = endPoint
        
        // Insert the new layer at the bottom-most position
        // This way we won't cover any other elements
        self.layer.insertSublayer(gradient, at: 0)
    }
}

Examples on how to use the extension:

// Testing
view.addGradient()
        
// Two Colors
view.addGradient(colors: [.init(rgb: 0x75BBDB), .black], locations: [0, 3])
        
// Full Blown
view.addGradient(colors: [.init(rgb: 0x75BBDB), .black], locations: [0, 3], startPoint: CGPoint(x: 0.0, y: 1.5), endPoint: CGPoint(x: 1.0, y: 2.0), type: .axial)

Optionally, use the following to input hex numbers .init(rgb: 0x75BBDB)

extension UIColor {
   convenience init(red: Int, green: Int, blue: Int) {
       self.init(red: CGFloat(red) / 255.0, green: CGFloat(green) / 255.0, blue: CGFloat(blue) / 255.0, alpha: 1.0)
   }

   convenience init(rgb: Int) {
       self.init(
           red: (rgb >> 16) & 0xFF,
           green: (rgb >> 8) & 0xFF,
           blue: rgb & 0xFF
       )
   }
}

Try:

If myString like "*A*" Then

If you just want to change the legend title, you can do the following:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=True
)

g._legend.set_title("New Title")

Here's a video that will show you, step-by-step, how to export data to Excel. It's a great solution for 'one-off' problems where you need to export to Excel:
Ad-Hoc Reporting

The easy way is to change the extension to .command or no extension.

But that will open the Terminal, and you will have to close it. If you don't want to see any output, you can use Automator to create a Mac Application that you can double click, add to the dock, etc.

1. Open Automator application
2. Choose "Application" type
3. Type "run" in the Actions search box
4. Double click "Run Shell Script"
5. Click the Run button in upper right corner to test it.
6. File > Save to create the Application.

Are you tied to this library? Google Gson is very popular. I have myself not used it with Generics but their front page says Gson considers support for Generics very important.

You can use JsonBuilder for that.

Example Code:

import groovy.json.JsonBuilder

class Person {
    String name
    String address
}

def o = new Person( name: 'John Doe', address: 'Texas' )

println new JsonBuilder( o ).toPrettyString()

Consider using INTERSECT like this:

SELECT contactid WHERE flag = 'Volunteer' 
INTERSECT
SELECT contactid WHERE flag = 'Uploaded'

I think it it the most logistic solution.

Use the MemoryStream class, calling Encoding.GetBytes to turn your string into an array of bytes first.

Do you subsequently need a TextReader on the stream? If so, you could supply a StringReader directly, and bypass the MemoryStream and Encoding steps.

If you are already using Fabric/Firebase Crashlytics you can call

CommonUtils.isRooted(context)

This is the current implementation of that method:

public static boolean isRooted(Context context) {
    boolean isEmulator = isEmulator(context);
    String buildTags = Build.TAGS;
    if(!isEmulator && buildTags != null && buildTags.contains("test-keys")) {
        return true;
    } else {
        File file = new File("/system/app/Superuser.apk");
        if(file.exists()) {
            return true;
        } else {
            file = new File("/system/xbin/su");
            return !isEmulator && file.exists();
        }
    }
}

Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.

It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.

The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

How about instead of using an if inside the event, you unbind the event when the select class is applied? I'm guessing you add the class inside your code somewhere, so unbinding the event there would look like this:

$(element).addClass( 'selected' ).unbind( 'hover' );

The only downside is that if you ever remove the selected class from the element, you have to subscribe it to the hover event again.

If you are trying to generate thumbnails, you must first resize the image using imagecopyresampled();. You must resize the image so that the size of the smaller side of the image is equal to the corresponding side of the thumb.

For example, if your source image is 1280x800px and your thumb is 200x150px, you must resize your image to 240x150px and then crop it to 200x150px. This is so that the aspect ratio of the image won't change.

Here's a general formula for creating thumbnails:

$image = imagecreatefromjpeg($_GET['src']);
$filename = 'images/cropped_whatever.jpg';

$thumb_width = 200;
$thumb_height = 150;

$width = imagesx($image);
$height = imagesy($image);

$original_aspect = $width / $height;
$thumb_aspect = $thumb_width / $thumb_height;

if ( $original_aspect >= $thumb_aspect )
{
   // If image is wider than thumbnail (in aspect ratio sense)
   $new_height = $thumb_height;
   $new_width = $width / ($height / $thumb_height);
}
else
{
   // If the thumbnail is wider than the image
   $new_width = $thumb_width;
   $new_height = $height / ($width / $thumb_width);
}

$thumb = imagecreatetruecolor( $thumb_width, $thumb_height );

// Resize and crop
imagecopyresampled($thumb,
                   $image,
                   0 - ($new_width - $thumb_width) / 2, // Center the image horizontally
                   0 - ($new_height - $thumb_height) / 2, // Center the image vertically
                   0, 0,
                   $new_width, $new_height,
                   $width, $height);
imagejpeg($thumb, $filename, 80);

Haven't tested this but it should work.

EDIT

Now tested and working.

ForGetMethod and passing two parameter :

          Client client = Client.create();
           WebResource webResource1 = client
                        .resource("http://localhost:10102/NewsTickerServices/AddGroup/"
                                + userN + "/" + groupName);

                ClientResponse response1 = webResource1.get(ClientResponse.class);
                System.out.println("responser is" + response1);

GetMethod passing one parameter and Getting a Respone of List :

       Client client = Client.create();

        WebResource webResource1 = client
                    .resource("http://localhost:10102/NewsTickerServices/GetAssignedUser/"+grpName);

    for (int i =0;i<jsonArr2.length();i++){

        Assignedlist.add(jsonArr2.getString(i));    
    }

In Above It Returns a List which we are accepting as a List and then converting it to Json Array and then Json Array to List .

If Post Request passing Json Object as Parameter :

   Client client = Client.create();
    WebResource webResource = client
            .resource("http://localhost:10102/NewsTickerServices/CreateJUser");
    // value added

    ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).post(ClientResponse.class,mapper.writeValueAsString(user));

    if (response.getStatus() == 500) {

        context.addMessage(null, new FacesMessage("User already exist "));
    }

df.dropna(subset=['columnName1', 'columnName2'])

Apart from the methods mentioned earlier. You can also use the command del to remove multiple variables

del variable1,variable2

Breaking news: I've added another answer that uses an Observable rather than an EventEmitter. I recommend that answer over this one. And actually, using an EventEmitter in a service is bad practice.

Original answer: (don't do this)

Put the EventEmitter into a service, which allows the ObservingComponent to directly subscribe (and unsubscribe) to the event:

import {EventEmitter} from 'angular2/core';

export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emit(number) {
    this.navchange.emit(number);
  }
  subscribe(component, callback) {
    // set 'this' to component when callback is called
    return this.navchange.subscribe(data => call.callback(component, data));
  }
}

@Component({
  selector: 'obs-comp',
  template: 'obs component, index: {{index}}'
})
export class ObservingComponent {
  item: number;
  subscription: any;
  constructor(private navService:NavService) {
   this.subscription = this.navService.subscribe(this, this.selectedNavItem);
  }
  selectedNavItem(item: number) {
    console.log('item index changed!', item);
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">item 1 (click me)</div>
  `,
})
export class Navigation {
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emit(item);
  }
}

If you try the Plunker, there are a few things I don't like about this approach:

• ObservingComponent needs to unsubscribe when it is destroyed
• we have to pass the component to subscribe() so that the proper this is set when the callback is called

Update: An alternative that solves the 2nd bullet is to have the ObservingComponent directly subscribe to the navchange EventEmitter property:

constructor(private navService:NavService) {
   this.subscription = this.navService.navchange.subscribe(data =>
     this.selectedNavItem(data));
}

If we subscribe directly, then we wouldn't need the subscribe() method on the NavService.

To make the NavService slightly more encapsulated, you could add a getNavChangeEmitter() method and use that:

getNavChangeEmitter() { return this.navchange; }  // in NavService

constructor(private navService:NavService) {  // in ObservingComponent
   this.subscription = this.navService.getNavChangeEmitter().subscribe(data =>
     this.selectedNavItem(data));
}

If you want to round a number, you can obtain different results depending on: how you use the Math.Round() function (if for a round-up or round-down), you're working with doubles and/or floats numbers, and you apply the midpoint rounding. Especially, when using with operations inside of it or the variable to round comes from an operation. Let's say, you want to multiply these two numbers: 0.75 * 0.95 = 0.7125. Right? Not in C#

Let's see what happens if you want to round to the 3rd decimal:

double result = 0.75d * 0.95d; // result = 0.71249999999999991
double result = 0.75f * 0.95f; // result = 0.71249997615814209

result = Math.Round(result, 3, MidpointRounding.ToEven); // result = 0.712. Ok
result = Math.Round(result, 3, MidpointRounding.AwayFromZero); // result = 0.712. Should be 0.713

As you see, the first Round() is correct if you want to round down the midpoint. But the second Round() it's wrong if you want to round up.

This applies to negative numbers:

double result = -0.75 * 0.95;  //result = -0.71249999999999991
result = Math.Round(result, 3, MidpointRounding.ToEven); // result = -0.712. Ok
result = Math.Round(result, 3, MidpointRounding.AwayFromZero); // result = -0.712. Should be -0.713

So, IMHO, you should create your own wrap function for Math.Round() that fit your requirements. I created a function in which, the parameter 'roundUp=true' means to round to next greater number. That is: 0.7125 rounds to 0.713 and -0.7125 rounds to -0.712 (because -0.712 > -0.713). This is the function I created and works for any number of decimals:

double Redondea(double value, int precision, bool roundUp = true)
{
    if ((decimal)value == 0.0m)
        return 0.0;

    double corrector = 1 / Math.Pow(10, precision + 2);

    if ((decimal)value < 0.0m)
    {
        if (roundUp)
            return Math.Round(value, precision, MidpointRounding.ToEven);
        else
            return Math.Round(value - corrector, precision, MidpointRounding.AwayFromZero);
    }
    else
    {
        if (roundUp)
            return Math.Round(value + corrector, precision, MidpointRounding.AwayFromZero);
        else
            return Math.Round(value, precision, MidpointRounding.ToEven);
    }
}

The variable 'corrector' is for fixing the inaccuracy of operating with floating or double numbers.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

Not sure, but it looks like you have a syntax error in your code. Try:

$.ajax({
  type: 'POST',
  url: url,
  data: postedData,
  dataType: 'json',
  success: callback
});

You had extra brackets next to $.ajax which were not needed. If you still get the error, then the jQuery script file is not loaded.

Can do this thru a plug-in like Java applet or Flash, then have the Javascript call a function in the applet or vice versa (OR have the JS call a function in Flash or other plugin ) and return the IP. This might not be the IP used by the browser for getting the page contents. Also if there are images, css, js -> browser could have made multiple connections. I think most browsers only use the first IP they get from the DNS call (that connected successfully, not sure what happens if one node goes down after few resources are got and still to get others - timers/ ajax that add html that refer to other resources).

If java applet would have to be signed, make a connection to the window.location (got from javascript, in case applet is generic and can be used on any page on any server) else just back to home server and use java.net.Address to get IP.

The <!-- --> is only for HTML commenting and the PHP will still run anyway...

Therefore the best thing I would do is also to comment out the PHP...

To represent a unicode string as a string of bytes is known as encoding. Use u'...'.encode(encoding).

Example:

    >>> u'æøå'.encode('utf8')
    '\xc3\x83\xc2\xa6\xc3\x83\xc2\xb8\xc3\x83\xc2\xa5'
    >>> u'æøå'.encode('latin1')
    '\xc3\xa6\xc3\xb8\xc3\xa5'
    >>> u'æøå'.encode('ascii')
    UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: 
    ordinal not in range(128)

You typically encode a unicode string whenever you need to use it for IO, for instance transfer it over the network, or save it to a disk file.

To convert a string of bytes to a unicode string is known as decoding. Use unicode('...', encoding) or '...'.decode(encoding).

Example:

   >>> u'æøå'
   u'\xc3\xa6\xc3\xb8\xc3\xa5' # the interpreter prints the unicode object like so
   >>> unicode('\xc3\xa6\xc3\xb8\xc3\xa5', 'latin1')
   u'\xc3\xa6\xc3\xb8\xc3\xa5'
   >>> '\xc3\xa6\xc3\xb8\xc3\xa5'.decode('latin1')
   u'\xc3\xa6\xc3\xb8\xc3\xa5'

You typically decode a string of bytes whenever you receive string data from the network or from a disk file.

I believe there are some changes in unicode handling in python 3, so the above is probably not correct for python 3.

Some good links:

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
• Unicode HOWTO

The Array index only accepts a long value.

You declared iCounter as an integer. You should declare it as a long.

I got a similar error, the problem stopped when I checked my "Linker -> Input -> Additional Dependencies" list in the project properties. I was missing a semi colon ";" just before "%(AdditionalDependencies)". I also had the same entry in twice. You should edit this list separately for Debug and Release.

The code snippet in the linked proposed duplicate reads user input.

ECHO A current build of Test Harness exists.
set /p delBuild=Delete preexisting build [y/n]?: 

The user can type as many letters as they want, and it will go into the delBuild variable.

This can be done without the use of hidden field. You have to take benefit of the JQuerys ability to make custom attributes on run time.

('#selector').autocomplete({
    source: url,
    select: function (event, ui) {
        $("#txtAllowSearch").val(ui.item.label); // display the selected text
        $("#txtAllowSearch").attr('item_id',ui.item.value); // save selected id to hidden input
    }
});

$('#button').click(function() {
    alert($("#txtAllowSearch").attr('item_id')); // get the id from the hidden input
}); 

I used this below if this is what you are thinking. It it worked well for me.

<?php
    include $_SERVER['DOCUMENT_ROOT']."/head_lib.php";
?>

What I was trying to do was pulla file called /head_lib.php from the root folder. It would not pull anything to build the webpage. The header, footer and other key features in sub directories would never show up. Until I did above it worked like a champ.

Regex isn't needed, nor is plugins

if (isNaN($('#Field').val() / 1) == false) {

Good post, the line

props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

is mandatory if the SMTP server uses SSL Authentication, like the GMail SMTP server does. However if the server uses Plaintext Authentication over TLS, it should not be present, because Java Mail will complain about the initial connection being plaintext.

Also make sure you are using the latest version of Java Mail. Recently I used some old Java Mail jars from a previous project and could not make the code work, because the login process was failing. After I have upgraded to the latest version of Java Mail, the reason of the error became clear: it was a javax.net.ssl.SSLHandshakeException, which was not thrown up in the old version of the lib.

The text inside $type is substituted directly into the insert string, therefore MySQL gets this:

... VALUES(testing, 'john', 'whatever')

Notice that there are no quotes around testing, you need to put these in like so:

$type = 'testing';
mysql_query("INSERT INTO contents (type, reporter, description) VALUES('$type', 'john', 'whatever')");

I also recommend you read up on SQL injection, as this sort of parameter passing is prone to hacking attempts if you do not sanitize the data being used:

• MySQL - SQL Injection Prevention

You basically need to do this:

• include the target hash into the link pointing to the other page (href="other_page.html#section")
• in your ready handler clear the hard jump scroll normally dictated by the hash and as soon as possible scroll the page back to the top and call jump() - you'll need to do this asynchronously
• in jump() if no event is given, make location.hash the target
• also this technique might not catch the jump in time, so you'll better hide the html,body right away and show it back once you scrolled it back to zero

This is your code with the above added:

var jump=function(e)
{
   if (e){
       e.preventDefault();
       var target = $(this).attr("href");
   }else{
       var target = location.hash;
   }

   $('html,body').animate(
   {
       scrollTop: $(target).offset().top
   },2000,function()
   {
       location.hash = target;
   });

}

$('html, body').hide();

$(document).ready(function()
{
    $('a[href^=#]').bind("click", jump);

    if (location.hash){
        setTimeout(function(){
            $('html, body').scrollTop(0).show();
            jump();
        }, 0);
    }else{
        $('html, body').show();
    }
});

Verified working in Chrome/Safari, Firefox and Opera. I don't know about IE though.

In Managed C++, static class syntax is:-

public ref class BitParser abstract sealed
{
    public:
        static bool GetBitAt(...)
        {
            ...
        }
}

... better late than never...

This works for deleting all the directories and files within a directory.

#include <iostream>
#include <cstring>
#include <cstdlib>
using namespace std;
int main()
{
    cout << "Enter the DirectoryName to Delete : ";
    string directoryName;
    cin >> directoryName;
    string a = "rmdir /s /q " + directoryName;
    system(a.c_str());
    return 0;
}

For Swift:

AVPlayer:

let player = AVPlayer(URL: NSURL(string: "http://www.sample.com/movie.mov"))
if (player.rate != 0 && player.error == nil) {
   println("playing")
}

Update:
player.rate > 0 condition changed to player.rate != 0 because if video is playing in reverse it can be negative thanks to Julian for pointing out.
Note: This might look same as above(Maz's) answer but in Swift '!player.error' was giving me a compiler error so you have to check for error using 'player.error == nil' in Swift.(because error property is not of 'Bool' type)

AVAudioPlayer:

if let theAudioPlayer =  appDelegate.audioPlayer {
   if (theAudioPlayer.playing) {
       // playing
   }
}

AVQueuePlayer:

if let theAudioQueuePlayer =  appDelegate.audioPlayerQueue {
   if (theAudioQueuePlayer.rate != 0 && theAudioQueuePlayer.error == nil) {
       // playing
   }
}

You reference a Linux distribution, so you need to install the readline development libraries

On Debian based platforms, like Ubuntu, you can run:

sudo apt-get install libreadline-dev 

and that should install the correct headers in the correct places,.

If you use a platform with yum, like SUSE, then the command should be:

yum install readline-devel

b1 = (Button) findViewById(R.id.click_me);
        b1.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                Intent i = new Intent(MainActivity.this, SecondActivity.class);
                startActivity(i);

            }
        });

I had the same problem as you. I have solved it in the next steps. In the command line you have to type just

1. "svn cleanup"--> run ,than
2. "svn update" --> run

and you have to check it ,that your App. is working without any failures or not, and if everything is ok, you can commit your changes.

The element cannot directly inherit from <body> tag. You can try to put it in a <dir style="padding-left:0px;"></dir> tag.

Using with hooks :

This answer would be helpful if your content dimension changes after loading.

onreadystatechange : Occurs when the load state of the data that belongs to an element or a HTML document changes. The onreadystatechange event is fired on a HTML document when the load state of the page's content has changed.

import {useState, useEffect, useRef} from 'react';
const ref = useRef();
useEffect(() => {
    document.onreadystatechange = () => {
      console.log(ref.current.clientHeight);
    };
  }, []);

I was trying to work with a youtube video player embedding whose dimensions may change after loading.

Wow, you have a huge misunderstanding how asp.net works.

This line of code

System.Diagnostics.Process.Start("help/AdminTutorial.html");

Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.

A very easy solution would be to change the href attribute of the link in you page_load method.

Your aspx code:

<a href="#" runat="server" id="myLink">Tutorial</a>

Your codebehind / cs code of page_load:

...
if (userinfo.user == "Admin")
{
  myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else 
{
  myLink.Attributes["href"] = "help/otherSite.html";
}
...

Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.

In Access VBA I've used this to turn off all the dialogs when running a bunch of updates:

DoCmd.SetWarnings False

After running all the updates, the last step in my VBA script is:

DoCmd.SetWarnings True

Hope this helps.

The update statement in all versions of SQL looks like:

update table
    set col1 = expr1,
        col2 = expr2,
        . . .
        coln = exprn
    where some condition

So, the answer is that you separate the assignments using commas and don't repeat the set statement.

I will add another answer which is the fastest one possible ?(yes, even more than the accepted answer), BUT it will not work for every single case. HOWEVER, it WILL work for every conceivable scenario:

You can simply use String as intermediate. Note, this WILL give you the correct result even though it seems like using String might yield the wrong results AS LONG AS YOU KNOW YOU'RE WORKING WITH "NORMAL" STRINGS. This is a method to increase effectiveness and make the code simpler which in return must use some assumptions on the data strings it operates on.

Con of using this method: If you're working with some ASCII characters like these symbols in the beginning of the ASCII table, the following lines might fail, but let's face it - you probably will never use them anyway.

Pro of using this method: Remember that most people usually work with some normal strings without any unusual characters and then the method is the simplest and fastest way to go.

from Long to byte[]:

byte[] arr = String.valueOf(longVar).getBytes();

from byte[] to Long:

long longVar = Long.valueOf(new String(byteArr)).longValue();

You can also use Dot(.) for local key i.e;

Data Source=.\SQLEXPRESS;Initial Catalog=master;Integrated Security=True

If you have the default server instance i.e. MSSQLSERVER, then just use dot for Data Source.

Data Source=.;Initial Catalog=master;Integrated Security=True

For me the problem was that changing the value for this field didn`t work:

$('#cardNumber').val(maskNumber);

None of the solutions above worked for me so I investigated further and found:

According to DOM Level 2 Event Specification: The change event occurs when a control loses the input focus and its value has been modified since gaining focus. That means that change event is designed to fire on change by user interaction. Programmatic changes do not cause this event to be fired.

The solution was to add the trigger function and cause it to trigger change event like this:

$('#cardNumber').val(maskNumber).trigger('change');

To make this complete: while others now solved your problem :) I would like to give you a piece of good advice: don't reinvent the wheel.

size_t forward_length = strlen(forward);

sp_help will give you a whole bunch of information about a table including the columns, keys and constraints. For example, running

exec sp_help 'Address' 

will give you information about Address.

You can calculate the number of minutes and hours from the number of seconds by simple division:

seconds = 12345
minutes = seconds // 60
hours = minutes // 60

print "%02d:%02d:%02d" % (hours, minutes % 60, seconds % 60)
print "%02d:%02d" % (minutes, seconds % 60)

Here // is Python's integer division.

This is the best one I've found.

IsisCode gives you a good solution. Another one is to position border div inside parent div. Check this example http://jsfiddle.net/A2tu9/

UPD: You can also use pseudo element :after (:before), in this case HTML will not be polluted with extra markup:

.my-div {
    position: relative;
    padding: 4px;
    ...
}
.my-div:after {
    content: '';
    position: absolute;
    top: -3px;
    left: -3px;
    bottom: -3px;
    right: -3px;
    border: 1px #888 solid;
}

Demo: http://jsfiddle.net/A2tu9/191/

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

From ping /?:

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet (IPv4-only).
    -i TTL         Time To Live.
    -v TOS         Type Of Service (IPv4-only. This setting has been deprecated
                   and has no effect on the type of service field in the IP Header).
    -r count       Record route for count hops (IPv4-only).
    -s count       Timestamp for count hops (IPv4-only).
    -j host-list   Loose source route along host-list (IPv4-only).
    -k host-list   Strict source route along host-list (IPv4-only).
    -w timeout     Timeout in milliseconds to wait for each reply.
    -R             Use routing header to test reverse route also (IPv6-only).
    -S srcaddr     Source address to use.
    -4             Force using IPv4.
    -6             Force using IPv6.

I know this isn't the best way to do it, but right click the button in question, events, key, key typed. This is a simple way to do it, but reacts to any key

I figured it out now. Here's the correct answer

CREATE PROCEDURE checkUser 
(
   brugernavn1 varchar(64),
   password varchar(64)
) 
BEGIN 
   SELECT COUNT(*) FROM bruger 
   WHERE bruger.brugernavn=brugernavn1 
   AND bruger.pass=password; 
END; 

@ points to a global var in mysql. The above syntax is correct.

I'd say @Wim is right. You should use ToString() for logfiles - assuming a technical audience - and Message, if at all, to display to the user. One could argue that even that is not suitable for a user, for every exception type and occurance out there (think of ArgumentExceptions, etc.).

Also, in addition to the StackTrace, ToString() will include information you will not get otherwise. For example the output of fusion, if enabled to include log messages in exception "messages".

Some exception types even include additional information (for example from custom properties) in ToString(), but not in the Message.

In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:

module tb;

byte b [4];

initial begin
    foreach (b[i]) b[i] = 1 << i;
    foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
    $finish;
end

endmodule

This prints out:

Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000

This is similar in concept to Marty's reg [7:0] a [0:3];. However, byte is a 2-state data type (0 and 1), but reg is 4-state (01xz). Using byte also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i]) loop syntax.

The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.

For those that just used a standard form submit (non-AJAX), there's another way to fire some Javascript/JQuery code upon completion of your action.

First, create a string property on your Model.

public class MyModel 
{
    public string JavascriptToRun { get; set;}
}

Now, bind to your new model property in the Javascript of your view:

<script type="text/javascript">
     @Model.JavascriptToRun
</script>

Now, also in your view, create a Javascript function that does whatever you need to do:

<script type="text/javascript">
     @Model.JavascriptToRun

     function ShowErrorPopup() {
          alert('Sorry, we could not process your order.');
     }

</script>

Finally, in your controller action, you need to call this new Javascript function:

[HttpPost]
public ActionResult PurchaseCart(MyModel model)
{
    // Do something useful
    ...

    if (success == false)
    {
        model.JavascriptToRun= "ShowErrorPopup()";
        return View(model);
    }
    else
        return RedirectToAction("Success");
}

You can convert both the values to lower case and compare.

Here is an example:

If LCase(Range("J6").Value) = LCase("Tawi") Then
   Range("J6").Value = "Tawi-Tawi"
End If

If you are trying to make more than just one folder on the root of the sdcard, ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"

then instead of folder.mkdir() you would use folder.mkdirs()

I've made this mistake in the past & I took forever to figure it out.

Change this code:

setTimeout(function(){this.setState({timePassed: true})}, 1000);

to the following:

setTimeout(()=>{this.setState({timePassed: true})}, 1000); 

How about checking with python code:

from tensorflow.python.platform import build_info as tf_build_info

print(tf_build_info.cudnn_version_number)
# 7 in v1.10.0

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)
            {
                var freshModel = GetModel(id);
                return View(freshModel);
            }

            // TODO: save selected answer in database
            // TODO: get next question based on selected answer (hard coded to 999 for now)

            var nextQuestionId = 999;
            return RedirectToAction("Index", "Home", new {id = nextQuestionId});
        }

        private QuizModel GetModel(int? questionId)
        {
            // just a stub, in lieu of a database

            var model = new QuizModel
            {
                QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
                QuestionId = 1,
                Responses = new List<Response>
                                                {
                                                    new Response
                                                        {
                                                            ChildQuestionId = 2,
                                                            ResponseId = 1,
                                                            ResponseDisplayText = "Red"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 3,
                                                            ResponseId = 2,
                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 4,
                                                            ResponseId = 3,
                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

For others like me who had a different but similar issue where the animation was not occurring at all:

From what I could find it may be something in my browser setting which preferred less motion for accessibility purposes. I could not find any setting in my browser, but I was able to get the animation working by downloading a local copy of bootstrap and commenting out this section of the CSS file:

@media (prefers-reduced-motion: reduce) {
  .collapsing {
    -webkit-transition: none;
    transition: none;
  }
}

If you need the URL till hostname and not the path use Apache's Common Lib StringUtil, and from URL extract the substring till third indexOf /.

public static String getURL(HttpServletRequest request){
   String fullURL = request.getRequestURL().toString();
   return fullURL.substring(0,StringUtils.ordinalIndexOf(fullURL, "/", 3)); 
}

Example: If fullURL is https://example.com/path/after/url/ then Output will be https://example.com

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"

You could also try to include md5-hash-sums or similar do determine whether there are any differences at all. Then, only compare files which have different hashes...

If you are using the Git Bash shell, you can use the following trick:

> webpage.html

This is actually the same as:

echo "" > webpage.html

Then, you can use git add webpage.html to stage the file.

Maybe you can just generate the sample of indices and then collect the items from your list.

randIndex = random.sample(range(len(mylist)), sample_size)
randIndex.sort()
rand = [mylist[i] for i in randIndex]

That code should work, but you need to include the localization in your page (it isn't included by default). Try putting this in your <head> tag, somewhere after you include jQuery and jQueryUI:

<script type="text/javascript"
        src="https://raw.githubusercontent.com/jquery/jquery-ui/master/ui/i18n/datepicker-fr.js">
</script>

I can't find where this is documented on the jQueryUI site, but if you view the source of this demo you'll see that this is how they do it. Also, please note that including this JS file will set the datepicker defaults to French, so if you want only some datepickers to be in French, you'll have to set the default back to English.

You can find all languages here at github: https://github.com/jquery/jquery-ui/tree/master/ui/i18n

A method of an object that needs to use a "sleep" method such as the following:

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function () {
    this.DoSomething1(arg1);
    sleep(500);
    this.DoSomething2(arg1);
}

Can almost be translated to:

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function (arg1) {
    var self = this;
    self.DoSomething1(arg1);
    setTimeout(function () {
        self.DoSomething2(arg1);
    }, 500);
}

The difference is that the operation of "SomeMethod" returns before the operation "DoSomething2" is executed. The caller of "SomeMethod" cannot depend on this. Since the "Sleep" method does not exists, I use the later method and design my code accordingly.

I hope this helps.

int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                    LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);        
imageView.setImageResource(id);        
someLinearLayout.addView(imageView); 

I was not able to clone a repository due to have logged on with other credentials.

To switch to another user, I >>desperate<< did:

git config --global --unset user.name
git config --global --unset user.email
git config --global --unset credential.helper

after, instead using ssh link, I used HTTPS link. It asked for credentials and it worked fine FOR ME!

app.factory('persistObject', function () {

        var persistObject = [];

        function set(objectName, data) {
            persistObject[objectName] = data;
        }
        function get(objectName) {
            return persistObject[objectName];
        }

        return {
            set: set,
            get: get
        }
    });

Fill it with data like this

persistObject.set('objectName', data); 

Get the object data like this

persistObject.get('objectName'); 

If you have a group of radio buttons sharing the same name attribute and upon submit or some event you want to check if one of these radio buttons was checked, you can do this simply by the following code :

$(document).ready(function(){
  $('#submit_button').click(function() {
    if (!$("input[name='name']:checked").val()) {
       alert('Nothing is checked!');
        return false;
    }
    else {
      alert('One of the radio buttons is checked!');
    }
  });
});

I think there may be problem that you haven't added click listener for ok positive button.

dlgAlert.setPositiveButton("Ok",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
          //dismiss the dialog  
        }
    });

Here's something which might be useful. Selecting the entire column based on a row containing data, in this case i am using 5th row:

Dim lColumn As Long

lColumn = ActiveSheet.Cells(5, Columns.Count).End(xlToLeft).Column
MsgBox ("The last used column is: " & lColumn)

cat foo.txt | strings -n 8 > bar.txt

will do the job.

pip show <package name> will provide the location for Windows and macOS, and I'm guessing any system. :)

For example:

> pip show cvxopt
Name: cvxopt
Version: 1.2.0
...
Location: /usr/local/lib/python2.7/site-packages

inside onstart command put START_STICKY... This service won't kill unless it is doing too much task and kernel wants to kill it for it...

@Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            Log.i("LocalService", "Received start id " + startId + ": " + intent);
            // We want this service to continue running until it is explicitly
            // stopped, so return sticky.
            return START_STICKY;
        }

Workspaces can only be open in one copy of eclipse at once. Further, you took away your own write access from the looks of it. All the users in question have to have the 'admin' group for what you did to even work a little.

...is there at least an easy way to check if it has a particular method other than simply checking if an error occurs when the method is called

While "Easier to ask for forgiveness than permission" is certainly the Pythonic way, you may be looking for:

d={'foo':'bar', 'spam':'eggs'}
if 'get' in dir(d):
    d.get('foo')
# OUT: 'bar'

Project Rebuild solved my problem.

In Android studio in the toolbar.. Build>Rebuild Project.

In Bash:

tail -1 ${filepath}_newstap.sh

Instead of using the windows load event use the ready event on the document.

$(document).ready(function(){[...]});

This should fire when everything in the DOM is ready to go, including media content fully loaded.

This is an old post, but I had a similar need and this is the solution I came up with. It is a bit of a hack, but it works and could be refined.

require 'erb'
require 'yaml'

doc = <<-EOF
  theme:
  name: default
  css_path: compiled/themes/<%= data['theme']['name'] %>
  layout_path: themes/<%= data['theme']['name'] %>
  image_path: <%= data['theme']['css_path'] %>/images
  recursive_path: <%= data['theme']['image_path'] %>/plus/one/more
EOF

data = YAML::load("---" + doc)

template = ERB.new(data.to_yaml);
str = template.result(binding)
while /<%=.*%>/.match(str) != nil
  str = ERB.new(str).result(binding)
end

puts str

A big downside is that it builds into the yaml document a variable name (in this case, "data") that may or may not exist. Perhaps a better solution would be to use $ and then substitute it with the variable name in Ruby prior to ERB. Also, just tested using hashes2ostruct which allows data.theme.name type notation which is much easier on the eyes. All that is required is to wrap the YAML::load with this

data = hashes2ostruct(YAML::load("---" + doc))

Then your YAML document can look like this

doc = <<-EOF
  theme:
  name: default
  css_path: compiled/themes/<%= data.theme.name %>
  layout_path: themes/<%= data.theme.name %>
  image_path: <%= data.theme.css_path %>/images
  recursive_path: <%= data.theme.image_path %>/plus/one/more
EOF

In Java 8, you could accomplish this by using LocalDate and DateTimeFormatter. From the Javadoc of LocalDate:

LocalDate is an immutable date-time object that represents a date, often viewed as year-month-day.

And the pattern can be constructed using DateTimeFormatter. Here is the Javadoc, and the relevant pattern characters I used:

Symbol - Meaning - Presentation - Examples

y - year-of-era - year - 2004; 04

M/L - month-of-year - number/text - 7; 07; Jul; July; J

d - day-of-month - number - 10

Here is the example:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.time.temporal.ChronoUnit;

public class Java8DateExample {
    public static void main(String[] args) throws IOException {
        final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd MM yyyy");
        final BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        final String firstInput = reader.readLine();
        final String secondInput = reader.readLine();
        final LocalDate firstDate = LocalDate.parse(firstInput, formatter);
        final LocalDate secondDate = LocalDate.parse(secondInput, formatter);
        final long days = ChronoUnit.DAYS.between(firstDate, secondDate);
        System.out.println("Days between: " + days);
    }
}

Example input/output with more recent last:

23 01 1997
27 04 1997
Days between: 94

With more recent first:

27 04 1997
23 01 1997
Days between: -94

Well, you could do it as a method in a simpler way:

public static long betweenDates(Date firstDate, Date secondDate) throws IOException
{
    return ChronoUnit.DAYS.between(firstDate.toInstant(), secondDate.toInstant());
}

In the sample, we are creating two datetime objects, one with current time and another one with 75 seconds added to the current time. Then we will call the method .Subtract() on the second DateTime object. This will return a TimeSpan object. Once we get the TimeSpan object, we can use the properties of TimeSpan to get the actual Hours, Minutes and Seconds.

DateTime startTime = DateTime.Now;

 DateTime endTime = DateTime.Now.AddSeconds( 75 );

 TimeSpan span = endTime.Subtract ( startTime );
 Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
 Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
 Console.WriteLine( "Time Difference (hours): " + span.Hours );
 Console.WriteLine( "Time Difference (days): " + span.Days );

Result:

Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0

If downloading from remote server, here is a simple example:

mysqldump -h my.address.amazonaws.com -u my_username -p db_name > /home/username/db_backup_name.sql

The -p indicates you will enter a password, it does not relate to the db_name. After entering the command you will be prompted for the password. Type it in and press enter.

For finding value use below

if let a = companies["AAPL"] {
   // a is the value
}

For traversing through the dictionary

for (key, value) in companies {
    print(key,"---", value)
}

Finally for searching key by value you firstly add the extension

extension Dictionary where Value: Equatable {
    func findKey(forValue val: Value) -> Key? {
        return first(where: { $1 == val })?.key
    }
}

Then just call

companies.findKey(val : "Apple Inc")

Are you putting this line inside the class declaration? In that case you should remove the JSONDeserializer::.

Assuming you don't want to make it a block element, then you might try:

.title  {
    display: inline-block; /* which allows you to set the height/width; but this isn't cross-browser, particularly as regards IE < 7 */
    line-height: 2em; /* or */
    padding-top: 1em;
    padding-bottom: 1em;
}

But the easiest solution is to simply treat the .title as a block-level element, and using the appropriate heading tags <h1> through <h6>.

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

This error means that for whatever reason the client cannot connect to the port on the computer running server script. This can be caused by few things, like lack of routing to the destination, but since you can ping the server, it should not be the case. The other reason might be that you have a firewall somewhere between your client and the server - it could be on server itself or on the client. Given your network addressing, I assume both server and client are on the same LAN, so there shouldn't be any router/firewall involved that could block the traffic. In this case, I'd try the following:

• check if you really have that port listening on the server (this should tell you if your code does what you think it should): based on your OS, but on linux you could do something like netstat -ntulp
• check from the server, if you're accepting the connections to the server: again based on your OS, but telnet LISTENING_IP LISTENING_PORT should do the job
• check if you can access the port of the server from the client, but not using the code: just us the telnet (or appropriate command for your OS) from the client

and then let us know the findings.

This may help:

ls -l| grep -v '^d'| awk '{total = total + $5} END {print "Total" , total}'

The above command will sum total all the files leaving the directories size.

using System.Windows.Forms;

public class message
{
    static void Main()
    {  
        MessageBox.Show("Hello World!"); 
    }
}

• Unique - Guarantees unique values for the column(or set of columns) included in the index
• Covering - Includes all of the columns that are used in a particular query (or set of queries), allowing the database to use only the index and not actually have to look at the table data to retrieve the results
• Clustered - This is way in which the actual data is ordered on the disk, which means if a query uses the clustered index for looking up the values, it does not have to take the additional step of looking up the actual table row for any data not included in the index.

Of course, as per all other comments here, this simply doesn't work.

I did once construct a simple java applet for a client which forced any capture of of an image to be done via screen capture and you might like to consider a similar technique. It worked, within the limitations, but I still think it was a waste of time.

I found the answer today. Maybe its too late but still I think its a much better one. Check this one https://jsfiddle.net/Amar_newDev/khb2oyru/5/

Try to change the CSS code : <ul> max-width:1%; margin:auto; text-align:left; </ul>

max-width:80% or something like that.

Try experimenting you might find something new.

Assuming exec() function declared in this post https://stackoverflow.com/a/46721603/653539 , sequences together with their last values can be fetched using single query:

select s.sequence_schema, s.sequence_name,
  (select * from exec('select last_value from ' || s.sequence_schema || '.' || s.sequence_name) as e(lv bigint)) last_value
from information_schema.sequences s

You must use an aggregate function on the columns against which you are not grouping. In this example, I arbitrarily picked the Min function. You are combining the rows with the same FruitType value. If I have two rows with the same FruitType value but different Fruit_Id values for example, what should the system do?

Select Min(tblFruit_id) As tblFruit_id
    , tblFruit_FruitType
From tblFruit
Group By tblFruit_FruitType

SQL Fiddle example

Here's what I use. If it fails to pretty print the JSON it just returns the original string. Useful for printing HTTP responses that should contain JSON.

import (
    "encoding/json"
    "bytes"
)

func jsonPrettyPrint(in string) string {
    var out bytes.Buffer
    err := json.Indent(&out, []byte(in), "", "\t")
    if err != nil {
        return in
    }
    return out.String()
}

Follow this:

• start Automator.app
• select Application
• click Show library in the toolbar (if hidden)
• add Run shell script (from the Actions/Utilities)
• copy & paste your script into the window
• test it

• save somewhere (for example you can make an Applications folder in your HOME, you will get an your_name.app)

• go to System Preferences -> Accounts -> Login items

• add this app
• test & done ;)

EDIT:

I've recently earned a "Good answer" badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb's answer, unless, you want interactivity.

With automator solution you can do things like next:

so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on...

The problem is that .click only works for elements already on the page. You have to use something like on if you are wiring up future elements

$("#LangTable").on("click",".deletelanguage", function(){
  alert("success");
});

len(list_name) function takes list as a parameter and it calls list's __len__() function.

 var svg = d3.select("body")
        .append("svg")
        .style("width", 200)
        .style("height", 100)

You can use the DevExpress PdfDocumentProcessor.Print(PdfPrinterSettings) Method.

public void Print(string pdfFilePath)
{
      if (!File.Exists(pdfFilePath))
          throw new FileNotFoundException("No such file exists!", pdfFilePath);

      // Create a Pdf Document Processor instance and load a PDF into it.
      PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor();
      documentProcessor.LoadDocument(pdfFilePath);

      if (documentProcessor != null)
      {
          PrinterSettings settings = new PrinterSettings();

          //var paperSizes = settings.PaperSizes.Cast<PaperSize>().ToList();
          //PaperSize sizeCustom = paperSizes.FirstOrDefault<PaperSize>(size => size.Kind == PaperKind.Custom); // finding paper size

          settings.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 600);

          // Print pdf
          documentProcessor.Print(settings);
      }
}

Assuming AdvancedFormat is a bool, you need to declare and use a BooleanToVisibilityConverter:

<!-- In your resources section of the XAML -->
<BooleanToVisibilityConverter x:Key="BoolToVis" />

<!-- In your Button declaration -->
<Button
 Height="50" Width="50"
 Style="{StaticResource MyButtonStyle}"
 Command="{Binding SmallDisp}" CommandParameter="{Binding}" 
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat, Converter={StaticResource BoolToVis}}"/>

Note the added Converter={StaticResource BoolToVis}.

This is a very common pattern when working with MVVM. In theory you could do the conversion yourself on the ViewModel property (i.e. just make the property itself of type Visibility) though I would prefer not to do that, since now you are messing with the separation of concerns. An item's visbility should really be up to the View.

Also, a good reason to use a controller vs. link function (since they both have access to the scope, element, and attrs) is because you can pass in any available service or dependency into a controller (and in any order), whereas you cannot do that with the link function. Notice the different signatures:

controller: function($scope, $exceptionHandler, $attr, $element, $parse, $myOtherService, someCrazyDependency) {...

vs.

link: function(scope, element, attrs) {... //no services allowed

It's my understanding that the original GetHashCode() returns the memory address of the object, so it's essential to override it if you wish to compare two different objects.

EDITED: That was incorrect, the original GetHashCode() method cannot assure the equality of 2 values. Though objects that are equal return the same hash code.

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

• Refresh your tables.
• Restart the SQL server.
• Look out for the spelling mistakes in Query.
