There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.

I had the same when following MvcMusicStore Tutorial in Part 4 and replaced the given connection String with this:

add name="MusicStoreEntities" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;database=MvcMusicStore;User ID=sa;password=" providerName="System.Data.SqlClient"/>

It worked for me.

One of your tables has the same column name's which brings a confusion in the query as to which columns of the tables are you referring to. Copy this code and run it.

SELECT 
    v.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount
FROM Vendors AS v
JOIN Invoices AS i ON (v.VendorID = .VendorID)
JOIN InvoiceLineItems AS iL ON (i.InvoiceID = iL.InvoiceID)
WHERE  
    I.InvoiceID IN
        (SELECT iL.InvoiceSequence 
         FROM InvoiceLineItems
         WHERE iL.InvoiceSequence > 1)
ORDER BY 
    V.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount

The sed on macOS Mojave was released in 2005, so one solution is to install the gnu-sed,

brew install gnu-sed

then use gsed will do as you wish,

gsed 's/,/\n/g' file

If you prefer sed, just sudo sh -c 'echo /usr/local/opt/gnu-sed/libexec/gnubin > /etc/paths.d/brew', which is suggested by brew info gnu-sed. Restart your term, then your sed in command line is gsed.

In Simple Words -

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

Here is a link to get clear understanding : MDN Web Docs

'use strict';

angular.module('cloudApp')
  .controller('MenuController', function ($scope, $location, CloudAuth) {
    $scope.menu = [
      {
        'title': 'Dashboard',
        'iconClass': 'fa fa-dashboard',
        'link': '/dashboard',
        'active': true
      },
      {
        'title': 'Devices',
        'iconClass': 'fa fa-star',
        'link': '/devices'
      },
      {
        'title': 'Settings',
        'iconClass': 'fa fa-gears',
        'link': '/settings'
      }
    ];
    $location.path('/dashboard');
    $scope.isLoggedIn = CloudAuth.isLoggedIn;
    $scope.isAdmin = CloudAuth.isAdmin;
    $scope.isActive = function(route) {
      return route === $location.path();
    };
  });

And use the below in the template:

<li role="presentation" ng-class="{active:isActive(menuItem.link)}" ng-repeat="menuItem in menu"><a href="{{menuItem.link}}"><i class="{{menuItem.iconClass}}"></i>&nbsp;&nbsp;{{menuItem.title}}</a></li>

I was looking for a pretty and simple solution and I found this:

this.setState({ [`image${i}`]: image })

Hope this helps

I'm surprised AutoMapper hasn't come up as an answer.

As is clear from all the previous answers, you cannot do the typecast. However, using AutoMapper, in a few lines of code you can have a new SkyfilterClient instantiated based on an existing NetworkClient.

In essence, you would put the following where you are currently doing your typecasting:

using AutoMapper;
...
// somewhere, your network client was declared
var existingNetworkClient = new NetworkClient();
...
// now we want to type-cast, but we can't, so we instantiate using AutoMapper
AutoMapper.Mapper.CreateMap<NetworkClient, SkyfilterClient>();
var skyfilterObject = AutoMapper.Mapper.Map<SkyfilterClient>(existingNetworkClient);

Here's a full-blown example:

  public class Vehicle
  {
    public int NumWheels { get; set; }
    public bool HasMotor { get; set; }
  }

  public class Car: Vehicle
  {
    public string Color { get; set; }
    public string SteeringColumnStyle { get; set; }
  }

  public class CarMaker
  {
    // I am given vehicles that I want to turn into cars...
    public List<Car> Convert(List<Vehicle> vehicles)
    {
      var cars = new List<Car>();
      AutoMapper.Mapper.CreateMap<Vehicle, Car>(); // Declare that we want some automagic to happen
      foreach (var vehicle in vehicles)
      {
        var car = AutoMapper.Mapper.Map<Car>(vehicle);
        // At this point, the car-specific properties (Color and SteeringColumnStyle) are null, because there are no properties in the Vehicle object to map from.
        // However, car's NumWheels and HasMotor properties which exist due to inheritance, are populated by AutoMapper.
        cars.Add(car);
      }
      return cars;
    }
  }

It is a function that has no name. For e.g. in c# you can use

numberCollection.GetMatchingItems<int>(number => number > 5);

to return the numbers that are greater than 5.

number => number > 5

is the lambda part here. It represents a function which takes a parameter (number) and returns a boolean value (number > 5). GetMatchingItems method uses this lambda on all the items in the collection and returns the matching items.

If you have more than this in javascript consider some javascript library, e.g. jquery which takes away a little speed, but gives you more readable code.

Your question's code via jquery:

$("td").hide();

Of course there are other javascript libraries out there, as this comparison on wikipedia shows.

just change the path:

"c:\program files\android\sdk" to "c:\progra~1\android\sdk"
or
"c:\program files (x86)\android\sdk" to "c:\progra~2\android\sdk"

note that the paths should not contain spaces.

Use smem, which is an alternative to ps which calculates the USS and PSS per process. You probably want the PSS.

• USS - Unique Set Size. This is the amount of unshared memory unique to that process (think of it as U for unique memory). It does not include shared memory. Thus this will under-report the amount of memory a process uses, but it is helpful when you want to ignore shared memory.

• PSS - Proportional Set Size. This is what you want. It adds together the unique memory (USS), along with a proportion of its shared memory divided by the number of processes sharing that memory. Thus it will give you an accurate representation of how much actual physical memory is being used per process - with shared memory truly represented as shared. Think of the P being for physical memory.

How this compares to RSS as reported by ps and other utilities:

• RSS - Resident Set Size. This is the amount of shared memory plus unshared memory used by each process. If any processes share memory, this will over-report the amount of memory actually used, because the same shared memory will be counted more than once - appearing again in each other process that shares the same memory. Thus it is fairly unreliable, especially when high-memory processes have a lot of forks - which is common in a server, with things like Apache or PHP (FastCGI/FPM) processes.

Notice: smem can also (optionally) output graphs such as pie charts and the like. IMO you don't need any of that. If you just want to use it from the command line like you might use ps -A v, then you don't need to install the Python and Matplotlib recommended dependency.

What you are looking for are Linked Servers. You can get to them in SSMS from the following location in the tree of the Object Explorer:

Server Objects-->Linked Servers

or you can use sp_addlinkedserver.

You only have to set up one. Once you have that, you can call a table on the other server like so:

select
    *
from
    LocalTable,
    [OtherServerName].[OtherDB].[dbo].[OtherTable]

Note that the owner isn't always dbo, so make sure to replace it with whatever schema you use.

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

josh3736's answer is a good one, but to provide a counterpoint 3 years later:

I recommend using rem units for fonts, if only because it makes it easier for you, the developer, to change sizes. It's true that users very rarely change the default font size in their browsers, and that modern browser zoom will scale up px units. But what if your boss comes to you and says "don't enlarge the images or icons, but make all the fonts bigger". It's much easier to just change the root font size and let all the other fonts scale relative to that, then to change px sizes in dozens or hundreds of css rules.

I think it still makes sense to use px units for some images, or for certain layout elements that should always be the same size regardless of the scale of the design.

Caniuse.com may have said that only 75% of browsers when josh3736 posted his answer in 2012, but as of March 27 they claim 93.78% support. Only IE8 doesn't support it among the browsers they track.

Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.

You can only do this in a loop:

[k for (k, v) in i.iteritems() if v == 0]

Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0} is perfectly legal.

If you want ordering you either need to use a list or a OrderedDict instance instead:

items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0]         # gives 'a'

I think what you are looking for is a utility which enables you to save a complete page opened in your browser into a png file. Most probably you are looking for a utility like commandlineprint2.

After installing the extension, you just need to type the command:

firefox -print http://google.com -printfile ~/foo.png

java 1.6.0_21 or later, or so...

$ java -XX:+PrintFlagsFinal -version 2>&1 | grep MaxHeapSize
uintx MaxHeapSize                         := 12660904960      {product}

It looks like the min(1G) has been removed.

Or on Windows using findstr

C:\>java -XX:+PrintFlagsFinal -version 2>&1 | findstr MaxHeapSize

Inorder to find an app's name (application label), you need to do the following:
(as shown in other answers)

1. Find the APK path of the app whose name you want to find.
2. Using aapt command, find the app label.

But devices don't ship with the aapt binary out-of-the-box.
So you will need to install it first. You can download it from here:
https://github.com/Calsign/APDE/tree/master/APDE/src/main/assets/aapt-binaries

Check this guide for complete steps:
How to find an app name using package name through ADB Android?
(Disclaimer: I am the author of that blog post)

And some times it started with double quotes, most of the times when you call API from dotNetCore 2 for getting file

string string64 = string64.Replace(@"""", string.Empty);
byte[] bytes = Convert.ToBase64String(string64);

<input type="number" name="numericInput" size="2" min="0" maxlength="2" value="0" />

Even I was thinking the same. If you open Activity Monitor you can see that it is downloading something at there on the name of GIT.

I found this tip useful.

https://stackoverflow.com/a/21916507/563735

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

Right. In most, if not all implementations of C, the array identifier can be implicitly casted to a pointer to the first element (i.e. the first element's address). What you're doing here is comparing those addresses, which is obviously wrong.

Instead, you need to iterate over both arrays, checking each element against each other. If you get to the end of both without a failure, they're equal.

You need to change the directory permission so that web server process can change the directory.

• To change ownership of the directory, use chown:

  chown -R user-id:group-id /path/to/the/directory
  

• To see which user own the web server process (change httpd accordingly):

  ps aux | grep httpd | grep -v grep
  

  OR

  ps -efl | grep httpd | grep -v grep
  

Assuming you are calling activity two from activity one using an Intent.
You can pass the data with the intent.putExtra(),

Take this for your reference. Sending arrays with Intent.putExtra

Hope that's what you want.

Wikipedia is built on MediaWiki, and here's the MediaWiki API.

"Casting" is different than conversion. In this case, window.location.hash will auto-convert a number to a string. But to avoid a TypeScript compile error, you can do the string conversion yourself:

window.location.hash = ""+page_number; 
window.location.hash = String(page_number); 

These conversions are ideal if you don't want an error to be thrown when page_number is null or undefined. Whereas page_number.toString() and page_number.toLocaleString() will throw when page_number is null or undefined.

When you only need to cast, not convert, this is how to cast to a string in TypeScript:

window.location.hash = <string>page_number; 
// or 
window.location.hash = page_number as string;

The <string> or as string cast annotations tell the TypeScript compiler to treat page_number as a string at compile time; it doesn't convert at run time.

However, the compiler will complain that you can't assign a number to a string. You would have to first cast to <any>, then to <string>:

window.location.hash = <string><any>page_number;
// or
window.location.hash = page_number as any as string;

So it's easier to just convert, which handles the type at run time and compile time:

window.location.hash = String(page_number); 

(Thanks to @RuslanPolutsygan for catching the string-number casting issue.)

Your conversion data is response[25] and follow the below steps.

var i = parseFloat(response[25]).toFixed(2)
console.log(i)//-6527.34

Most of the time spinner.setSelection(i); //i is 0 to (size-1) of adapter's size doesn't work. If you just call spinner.setSelection(i);

It depends on your logic.

If view is fully loaded and you want to call it from interface I suggest you to call

spinner.setAdapter(spinner_no_of_hospitals.getAdapter());
spinner.setSelection(i); // i is 0 or within adapter size

Or if you want to change between activity/fragment lifecycle, call like this

spinner.post(new Runnable() {
  @Override public void run() {
    spinner.setSelection(i);
  }
});

There are two main scenarios

You haven't pushed the commit yet

If the problem was extra files you commited (and you don't want those on repository), you can remove them using git rm and then commiting with --amend

git rm <pathToFile>

You can also remove entire directories with -r, or even combine with other Bash commands

git rm -r <pathToDirectory>
git rm $(find -name '*.class')

After removing the files, you can commit, with --amend option

git commit --amend -C HEAD # the -C option is to use the same commit message

This will rewrite your recent local commit removing the extra files, so, these files will never be sent on push and also will be removed from your local .git repository by GC.

You already pushed the commit

You can apply the same solution of the other scenario and then doing git push with the -f option, but it is not recommended since it overwrites the remote history with a divergent change (it can mess your repository).

Instead, you have to do the commit without --amend (remember this about -amend`: That option rewrites the history on the last commit).

Super simple in-place assignment: df['new'] = 0

For in-place modification, perform direct assignment. This assignment is broadcasted by pandas for each row.

df = pd.DataFrame('x', index=range(4), columns=list('ABC'))
df

   A  B  C
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x

df['new'] = 'y'
# Same as,
# df.loc[:, 'new'] = 'y'
df

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

Note for object columns

If you want to add an column of empty lists, here is my advice:

• Consider not doing this. object columns are bad news in terms of performance. Rethink how your data is structured.
• Consider storing your data in a sparse data structure. More information: sparse data structures

• If you must store a column of lists, ensure not to copy the same reference multiple times.

  # Wrong
  df['new'] = [[]] * len(df)
  # Right
  df['new'] = [[] for _ in range(len(df))]
  

Generating a copy: df.assign(new=0)

If you need a copy instead, use DataFrame.assign:

df.assign(new='y')

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

And, if you need to assign multiple such columns with the same value, this is as simple as,

c = ['new1', 'new2', ...]
df.assign(**dict.fromkeys(c, 'y'))

   A  B  C new1 new2
0  x  x  x    y    y
1  x  x  x    y    y
2  x  x  x    y    y
3  x  x  x    y    y

Multiple column assignment

Finally, if you need to assign multiple columns with different values, you can use assign with a dictionary.

c = {'new1': 'w', 'new2': 'y', 'new3': 'z'}
df.assign(**c)

   A  B  C new1 new2 new3
0  x  x  x    w    y    z
1  x  x  x    w    y    z
2  x  x  x    w    y    z
3  x  x  x    w    y    z

You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.

this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick); 

I hope it helps.

A Mocha test case example:

describe('Check version of node', function () {
    it('Should test version assert', async function () {

            var version = process.version;
            var check = parseFloat(version.substr(1,version.length)) > 12.0;
            console.log("version: "+version);
            console.log("check: " +check);         
            assert.equal(check, true);
    });});

You can do this also:

Let’s say df is your dataframe. Then df.shape gives you the shape of your dataframe i.e (row,col)

Thus, assign the below command to get the required

 row = df.shape[0], col = df.shape[1]

How do I check if an element exists

if ($("#mydiv").length){  }

If it is 0, it will evaluate to false, anything more than that true.

There is no need for a greater than, less than comparison.

When making many plots, it makes sense to set it globally (relevant part is the second line, three lines together are a working example):

For all Kotlin Users

You can create an Extension like following:

fun FragmentActivity.showCustomToast(message : String,color : Int) {
 val toastView = findViewById<TextView>(R.id.toast_view)
 toastView.text = message
 toastView.visibility = View.VISIBLE
 toastView.setBackgroundColor(color)

 // create a daemon thread
 val timer = Timer("schedule", true)

 // schedule a single event
 timer.schedule(2000) {
    runOnUiThread { toastView.visibility = View.GONE }
 }
}

Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

I've created a simple to use library (ss-search) which is designed to handle objects, but could also work in your case:

search(windowArray.map(x => ({ key: x }), ["key"], "SEARCH_TEXT").map(x => x.key)

The advantage of using this search function is that it will normalize the text before executing the search to return more accurate results.

I'm working with loading images for this answer and I want them to be scaled to the device's width. I find that, for older phones with versions less than API 19 (KitKat), the behavior for Brian's answer isn't quite as I like it. It puts a lot of whitespace around some images on older phones, but works on my newer one. Here is my alternative, with help from this answer: Can Android's WebView automatically resize huge images? The layout algorithm SINGLE_COLUMN is deprecated, but it works and I feel like it is appropriate for working with older webviews.

WebSettings settings = webView.getSettings();

// Image set to width of device. (Must be done differently for API < 19 (kitkat))
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    if (!settings.getLayoutAlgorithm().equals(WebSettings.LayoutAlgorithm.SINGLE_COLUMN))
        settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
} else {
    if (!settings.getLoadWithOverviewMode()) settings.setLoadWithOverviewMode(true);
    if (!settings.getUseWideViewPort()) settings.setUseWideViewPort(true);
}

The code is correct. The problem must lie somewhere else. Try the minimalistic example from the std::getline documentation.

main ()
{
    std::string name;

    std::cout << "Please, enter your full name: ";
    std::getline (std::cin,name);
    std::cout << "Hello, " << name << "!\n";

    return 0;
}

If you see this error when running tests, make sure you have imported the module the pipe belongs to, e.g.:

    beforeEach(async(() => {
        TestBed.configureTestingModule({
            imports: [CustomPipeModule],
            declarations: [...],
            providers: [...],
            ...
        }).compileComponents();
    }));

Your code actually works on FF, it doesn't work on Chrome.

This works on FF and Chrome.

$(document).ready(function() {
        // Solution for disabling the submit temporarily for all the submit buttons.
        // Avoids double form submit.
        // Doing it directly on the submit click made the form not to submit in Chrome.
        // This works in FF and Chrome.
        $('form').on('submit', function(e){
          //console.log('submit2', e, $(this).find('[clicked=true]'));
          var submit = $(this).find('[clicked=true]')[0];
          if (!submit.hasAttribute('disabled'))
          {
            submit.setAttribute('disabled', true);
            setTimeout(function(){
              submit.removeAttribute('disabled');
            }, 1000);
          }
          submit.removeAttribute('clicked');
          e.preventDefault();
        });
        $('[type=submit]').on('click touchstart', function(){
          this.setAttribute('clicked', true);
        });
      });
    </script>

Tnx @Raj_89 , Your trick was very good , can be better , only by use extra style , that make it on other dom objects , exactly like a common select option tag in html ...

select{
 position:absolute;
}

u can see result here : http://jsfiddle.net/aTzc2/

You'd need to wrap the two headings in a div tag, and have that div tag use a style that does clear: both. e.g:

<div style="clear: both">
    <h2 style="float: left">Heading 1</h2>
    <h3 style="float: right">Heading 2</h3>
</div>
<hr />

Having the hr after the div tag will ensure that it is pushed beneath both headers.

Or something very similar to that. Hope this helps.

It looks like what you really want is:

function xmlEntities($string) {
    $translationTable = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES);

    foreach ($translationTable as $char => $entity) {
        $from[] = $entity;
        $to[] = '&#'.ord($char).';';
    }
    return str_replace($from, $to, $string);
}

It replaces the named-entities with their number-equivalent.

With yield you can easily describe the breakpoints between multiple tasks in a single function. That's all, there is nothing special about it.

$closure = function ($injected1, $injected2, ...){
    $returned = array();
    //task1 on $injected1
    $returned[] = $returned1;
//I need a breakpoint here!!!!!!!!!!!!!!!!!!!!!!!!!
    //task2 on $injected2
    $returned[] = $returned2;
    //...
    return $returned;
};
$returned = $closure($injected1, $injected2, ...);

If task1 and task2 are highly related, but you need a breakpoint between them to do something else:

• free memory between processing database rows
• run other tasks which provide dependency to the next task, but which are unrelated by understanding the current code
• doing async calls and wait for the results
• and so on ...

then generators are the best solution, because you don't have to split up your code into many closures or mix it with other code, or use callbacks, etc... You just use yield to add a breakpoint, and you can continue from that breakpoint if you are ready.

Add breakpoint without generators:

$closure1 = function ($injected1){
    //task1 on $injected1
    return $returned1;
};
$closure2 = function ($injected2){
    //task2 on $injected2
    return $returned1;
};
//...
$returned1 = $closure1($injected1);
//breakpoint between task1 and task2
$returned2 = $closure2($injected2);
//...

Add breakpoint with generators

$closure = function (){
    $injected1 = yield;
    //task1 on $injected1
    $injected2 = (yield($returned1));
    //task2 on $injected2
    $injected3 = (yield($returned2));
    //...
    yield($returnedN);
};
$generator = $closure();
$returned1 = $generator->send($injected1);
//breakpoint between task1 and task2
$returned2 = $generator->send($injected2);
//...
$returnedN = $generator->send($injectedN);

note: It is easy to make mistake with generators, so always write unit tests before you implement them! note2: Using generators in an infinite loop is like writing a closure which has infinite length...

if you want get all values from form in simple array you may be do something like this.

function getValues(form) {
    var listvalues = new Array();
    var datastring = $("#" + form).serializeArray();
    var data = "{";
    for (var x = 0; x < datastring.length; x++) {
        if (data == "{") {
            data += "\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
        else {
            data += ",\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
    }
    data += "}";
    data = JSON.parse(data);
    listvalues.push(data);
    return listvalues;
};

mystring.replace (" ", "_")

if you assign this value to any variable, it will work

s = mystring.replace (" ", "_")

by default mystring wont have this

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

You need to add a '/' after the dir name

<exclude name="WEB-INF/" />

Just a little hint from my side for uploading HTML5 canvas image data:

I am working on a project for a print-shop and had some problems due to uploading images to the server that came from an HTML5 canvas element. I was struggling for at least an hour and I did not get it to save the image correctly on my server.

Once I set the contentType option of my jQuery ajax call to application/x-www-form-urlencoded everything went the right way and the base64-encoded data was interpreted correctly and successfully saved as an image.

Maybe that helps someone!

Same as C, you would do

#include <time.h>
#include <stdlib.h>
...
srand(time(NULL));
int r = rand() % 74;

(assuming you meant including 0 but excluding 74, which is what your Java example does)

Edit: Feel free to substitute random() or arc4random() for rand() (which is, as others have pointed out, quite sucky).

You can also do this:

NSNumber *number = @([dictionary[@"id"] intValue]]);

Have fun!

Byte[] Content = new BinaryReader(file.InputStream).ReadBytes(file.ContentLength);

just try to push it to your branch again. This will ask your username and password again, so you can feed in the changed password. So that your new password will be stored again in the cache.

Some dtype are not supported by specific OpenCV functions. For example inputs of dtype np.uint32 create this error. Try to convert the input to a supported dtype (e.g. np.int32 or np.float32)

It will depend of your php version. Check it running:

php -version

Now, according to your current version, run:

sudo apt-get install php7.2-mysql

Below is the fully qualified pattern for email validation.

<input type="text" pattern="/^[_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]*\.([a-z]{2,4})$/" ng-model="emailid" name="emailid"/>

<div ng-message="pattern">Please enter valid email address</div>

It depends on whether you are using JPA or Hibernate.

From the JPA 2.0 spec, the defaults are:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

And in hibernate, all is Lazy

UPDATE:

The latest version of Hibernate aligns with the above JPA defaults.

Another, perhaps simpler, solution is to add your override template directory to the DIRS entry of the TEMPLATES setting in settings.py. (I think this setting is new in Django 1.8. It may have been called TEMPLATE_DIRS in previous Django versions.)

Like so:

TEMPLATES = [
   {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        # allow overriding templates from other installed apps                                                                                                
        'DIRS': ['my_app/templates'],
        'APP_DIRS': True,
}]

Then put your override template files under my_app/templates. So the overridden password reset template would be my_app/templates/registration/password_reset_form.html

For latest browser, like Chrome, you can use the File API as in this tutorial:

window.requestFileSystem  = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.PERSISTENT, 5*1024*1024 /*5MB*/, saveFile, errorHandler);

d = {'Date': list(yourDict.keys()),'Date_Values': list(yourDict.values())}
df = pandas.DataFrame(data=d)

If you don't encapsulate yourDict.keys() inside of list() , then you will end up with all of your keys and values being placed in every row of every column. Like this:

Date \ 0 (2012-06-08, 2012-06-09, 2012-06-10, 2012-06-1...
1 (2012-06-08, 2012-06-09, 2012-06-10, 2012-06-1...
2 (2012-06-08, 2012-06-09, 2012-06-10, 2012-06-1...
3 (2012-06-08, 2012-06-09, 2012-06-10, 2012-06-1...
4 (2012-06-08, 2012-06-09, 2012-06-10, 2012-06-1...

But by adding list() then the result looks like this:

Date Date_Values 0 2012-06-08 388 1 2012-06-09 388 2 2012-06-10 388 3 2012-06-11 389 4 2012-06-12 389 ...

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}

Please find example below, it might help you

for testing you can use any tool like RestClient (http://code.google.com/p/rest-client/)

In a php section before the HTML section, use sprinf() to create a constant string from the variables:

$mystuff = sprinf("My name is %s and my mother's name is %s","Suzy","Caroline");

Then in the HTML section you can do whatever you like, such as:

<p>$mystuff</p> 

If that is the entire line, it very well might be because you are missing a ; at the end of the line.

It would be helpful if you can provide a code snippet of your maven-war-plugin. Looks like the web.xml is at right place, still you can try and give the location explicitly

<plugin>            
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-war-plugin</artifactId>
  <configuration>
    <webXml>src\main\webapp\WEB-INF\web.xml</webXml>        
  </configuration>
</plugin>

You want strtol or strtoul. See also the Unix man page

I have a crossplatform solution without any additional modules. I was looking for something like a try catch block I could use both in the cmd.exe and in the bash.

The solution is command1 || command2 which seems to work in both enviroments same. So the solution for the OP is:

"scripts": {
  "start-watch": "nodemon run-babel index.js",
  "wp-server": "webpack-dev-server",
  // first command is for the cmd.exe, second one is for the bash
  "dev": "(start npm run start-watch && start npm run wp-server) || (npm run start-watch & npm run wp-server)",
  "start": "npm run dev"
}

Then simple npm start (and npm run dev) will work on all platforms!

You can't really talk about slowness based on the data you provided in a question. And I don't think you should even worry too much about performance at this stage of developement. It's called premature optimization.

However, I'd suggest that you'd include Tag_ID column in the Tags table. It's usually a good practice that every table has an ID column.

window.location.reload() // without passing true as argument

works for me.

double a = 1.000001;
double b = 0.000001;

System.out.println( a.compareTo(b) );

Returns:

• -1 : 'a' is numerically less than 'b'.

• 0 : 'a' is equal to 'b'.

• 1 : 'a' is greater than 'b'.

When using SQLite:

REPLACE into table (id, name, age) values(1, "A", 19)

Provided that id is the primary key. Or else it just inserts another row. See INSERT (SQLite).

A slightly simplified answer:

public class Book
{
    private final String title;

    public Book(String title)
    {
      this.title = title;
    }

    public Book()
    {
      this("Default Title");
    }

    ...
}

Use following to call function of a frame in parent page

parent.document.getElementById('frameid').contentWindow.somefunction()

For +300k concurrent connection:

Set these variables in /etc/sysctl.conf:

fs.file-max = 10000000 
fs.nr_open = 10000000

Also, change these variables in /etc/security/limits.conf:

* soft nofile 10000000
* hard nofile 10000000
root soft nofile 10000000
root hard nofile 10000000

And finally, increase TCP buffers in /etc/sysctl.conf, too:

net.ipv4.tcp_mem = 786432 1697152 1945728
net.ipv4.tcp_rmem = 4096 4096 16777216
net.ipv4.tcp_wmem = 4096 4096 16777216

for more information please refer to this.

If you don't want to change your pattern you can use the Group Index and Length properties of a matched group.

var text = "example-123-example";
var pattern = @"-(\d+)-";
var regex = new RegEx(pattern);
var match = regex.Match(text);

var firstPart = text.Substring(0,match.Groups[1].Index);    
var secondPart = text.Substring(match.Groups[1].Index + match.Groups[1].Length);
var fullReplace = firstPart + "AA" + secondPart;

As it stands, there is no 'autocomplete off' attribute in CSS. However, html has an easy code for this:

<input type="text" id="foo" value="bar" autocomplete="off" />

If you're looking for a site-wide effector, an easy one would be to simply have a js function to run through all 'input' s and add this tag, or look for the corresponding css class / id.

The autocomplete attribute works fine in Chrome and Firefox (!), but see also Is there a W3C valid way to disable autocomplete in a HTML form?

Alternatively to Martin's answer, you could also add the INTO part at the end of the query to make the query more readable:

SELECT Id, dateCreated FROM products INTO iId, dCreate

You must extend the regional options like this (code split on multiple lines for readability):

var options = $.extend(
    {},                                  // empty object
    $.datepicker.regional["fr"],         // fr regional
    { dateFormat: "d MM, y" /*, ... */ } // your custom options
);
$("#datepicker").datepicker(options);

The order of parameters is important because of the way jQuery.extend works. Two incorrect examples:

/*
 * This overwrites the global variable itself instead of creating a
 * customized copy of french regional settings
 */
$.extend($.datepicker.regional["fr"], { dateFormat: "d MM, y"});

/*
 * The desired dateFormat is overwritten by french regional 
 * settings' date format
 */
$.extend({ dateFormat: "d MM, y"}, $.datepicker.regional["fr"]);

PS: you also need to load the jQuery UI i18n files:

<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/i18n/jquery-ui-i18n.min.js">
</script>

In order to sort a list of tuples (<word>, <count>), for count in descending order and word in alphabetical order:

data = [
('betty', 1),
('bought', 1),
('a', 1),
('bit', 1),
('of', 1),
('butter', 2),
('but', 1),
('the', 1),
('was', 1),
('bitter', 1)]

I use this method:

sorted(data, key=lambda tup:(-tup[1], tup[0]))

and it gives me the result:

[('butter', 2),
('a', 1),
('betty', 1),
('bit', 1),
('bitter', 1),
('bought', 1),
('but', 1),
('of', 1),
('the', 1),
('was', 1)]

use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)
{
 //do stuffs to change 
}

If you want to upload a folder or a file to Github

1- Create a repository on the Github

2- make: git remote add origin "Your Link" as it is described on the Github

3- Then use git push -u origin master.

4- You have to enter your username and Password.

5- After the authentication, the transfer will start

Give it a try: http://convertwebpage.com — this is a web-application that can convert web-pages into images (jpg, png) or into pdf and has some options.

you have to add fulltext index on specific fields you want to search.

ALTER TABLE news ADD FULLTEXT(headline, story);

where "news" is your table and "headline, story" fields you wont to enable for fulltext search

Auction.auctions = Auction.auctions.filter(function(el) {
  return --el["seconds"] > 0;
});

If you want to pass data to form2 from form1 without passing like new form(sting "data");

Do like that in form 1

using (Form2 form2= new Form2())
{
   form2.ReturnValue1 = "lalala";
   form2.ShowDialog();
}

in form 2 add

public string ReturnValue1 { get; set; }

private void form2_Load(object sender, EventArgs e)
{
   MessageBox.Show(ReturnValue1);
}

Also you can use value in form1 like this if you want to swap something in form1

just in form1

textbox.Text =form2.ReturnValue1

Did you check NULLIF? http://msdn.microsoft.com/en-us/library/ms177562.aspx

Please ignore all the invalidate(), invalidateViews(), requestLayout(), ... answers to this question.

The right thing to do (and luckily also marked as right answer) is to call notifyDataSetChanged() on your Adapter.

Troubleshooting

If calling notifyDataSetChanged() doesn't work all the layout methods won't help either. Believe me the ListView was properly updated. If you fail to find the difference you need to check where the data in your adapter comes from.

If this is just a collection you're keeping in memory check that you actually deleted from or added the item(s) to the collection before calling the notifyDataSetChanged().

If you're working with a database or service backend you'll have to call the method to retrieve the information again (or manipulate the in memory data) before calling the notifyDataSetChanged().

The thing is this notifyDataSetChanged only works if the dataset has changed. So that is the place to look if you don't find changes coming through. Debug if needed.

ArrayAdapter vs BaseAdapter

I did find that working with an adapter that lets you manage the collection, like a BaseAdapter works better. Some adapters like the ArrayAdapter already manage their own collection making it harder to get to the proper collection for updates. It's really just an needless extra layer of difficulty in most cases.

UI Thread

It is true that this has to be called from the UI thread. Other answers have examples on how to achieve this. However this is only required if you're working on this information from outside the UI thread. That is from a service or a non UI thread. In simple cases you'll be updating your data from a button click or another activity/fragment. So still within the UI thread. No need to always pop that runOnUiTrhead in.

Quick Example Project

Can be found at https://github.com/hanscappelle/so-2250770.git. Just clone and open the project in Android Studio (gradle). This project has a MainAcitivity building a ListView with all random data. This list can be refreshed using the action menu.

The adapter implementation I created for this example ModelObject exposes the data collection

public class MyListAdapter extends BaseAdapter {

    /**
     * this is our own collection of data, can be anything we 
     * want it to be as long as we get the abstract methods 
     * implemented using this data and work on this data 
     * (see getter) you should be fine
     */
    private List<ModelObject> mData;

    /**
     * our ctor for this adapter, we'll accept all the things 
     * we need here
     *
     * @param mData
     */
    public MyListAdapter(final Context context, final List<ModelObject> mData) {
        this.mData = mData;
        this.mContext = context;
    }

    public List<ModelObject> getData() {
        return mData;
    }

    // implement all abstract methods here
}

Code from the MainActivity

public class MainActivity extends Activity {

    private MyListAdapter mAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView list = (ListView) findViewById(R.id.list);

        // create some dummy data here
        List<ModelObject> objects = getRandomData();
        // and put it into an adapter for the list
        mAdapter = new MyListAdapter(this, objects);
        list.setAdapter(mAdapter);

        // mAdapter is available in the helper methods below and the 
        // data will be updated based on action menu interactions

        // you could also keep the reference to the android ListView 
        // object instead and use the {@link ListView#getAdapter()} 
        // method instead. However you would have to cast that adapter 
        // to your own instance every time
    }

    /**
     * helper to show what happens when all data is new
     */
    private void reloadAllData(){
        // get new modified random data
        List<ModelObject> objects = getRandomData();
        // update data in our adapter
        mAdapter.getData().clear();
        mAdapter.getData().addAll(objects);
        // fire the event
        mAdapter.notifyDataSetChanged();
    }

    /**
     * helper to show how only changing properties of data 
     * elements also works
     */
    private void scrambleChecked(){
        Random random = new Random();
        // update data in our adapter, iterate all objects and 
        // resetting the checked option
        for( ModelObject mo : mAdapter.getData()) {
            mo.setChecked(random.nextBoolean());
        }
        // fire the event
        mAdapter.notifyDataSetChanged();
    }
}

More Information

Another nice post about the power of listViews is found here: http://www.vogella.com/articles/AndroidListView/article.html

Or use this for different types of errors

function isError(val) {
  return (!!val && typeof val === 'object')
    && ((Object.prototype.toString.call(val) === '[object Error]')
      || (typeof val.message === 'string' && typeof val.name === 'string'))
}

I have a simple solution on handling home button press. Here is my code, it can be useful:

public class LifeCycleActivity extends Activity {


boolean activitySwitchFlag = false;

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        activitySwitchFlag = true;
        // activity switch stuff..
        return true;
    }
    return false;
}

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override 
public void onPause(){
    super.onPause();
    Log.v("TAG", "onPause" );
    if(activitySwitchFlag)
        Log.v("TAG", "activity switch");
    else
        Log.v("TAG", "home button");
    activitySwitchFlag = false;
}

public void gotoNext(View view){
    activitySwitchFlag = true;
    startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}

}

As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..

I've got the same error on a fully updated Windows Vista Family 64bit with a .NET application that I've compiled to 32 bit only - the program is installed in the programx86 folder on 64 bit machines. It fails with this error message even with 2007 access database provider installed, with/wiothout the SP2 of the same installed, IIS installed and app pool set for 32bit app support... yes I've tried every solution everywhere and still no success.

I switched my app to ACE OLE DB.12.0 because JET4.0 was failing on 64bit machines - and it's no better :-/ The most promising thread I've found was this:

http://ellisweb.net/2010/01/connecting-to-excel-and-access-files-using-net-on-a-64-bit-server/

but when you try to install the 64 bit "2010 Office System Driver Beta: Data Connectivity Components" it tells you that you can't install the 64 bit version without uninstalling all 32bit office applications... and installing the 32 bit version of 2010 Office System Driver Beta: Data Connectivity Components doesn't solve the initial problem, even with "Microsoft.ACE.OLEDB.12.0" as provider instead of "Microsoft.ACE.OLEDB.14.0" which that page (and others) recommend.

My next attempt will be to follow this post:

The issue is due to the wrong flavor of OLEDB32.DLL and OLEDB32r.DLL being registered on the server. If the 64 bit versions are registered, they need to be unregistered, and then the 32 bit versions registered instead. To fix this, unregister the versions located in %Program Files%/Common Files/System/OLE DB. Then register the versions at the same path but in the %Program Files (x86)% directory.

Has anyone else had so much trouble with both JET4.0 and OLEDB ACE providers on 64 bit machines? Has anyone found a solution if none of the others work?

The methods above work great. If you're using apache commons (org.apache.commons.math.random) check out RandomData. It has a method: nextLong(long lower, long upper)

http://commons.apache.org/math/userguide/random.html

http://commons.apache.org/math/api-1.1/org/apache/commons/math/random/RandomData.html#nextLong(long,%20long)

AFAIK, the only way this could be done is by using the state=directory option. While template module supports most of copy options, which in turn supports most file options, you can not use something like state=directory with it. Moreover, it would be quite confusing (would it mean that {{project_root}}/conf/code.conf is a directory ? or would it mean that {{project_root}}/conf/ should be created first.

So I don't think this is possible right now without adding a previous file task.

- file: 
    path: "{{project_root}}/conf"
    state: directory
    recurse: yes

   return /MSIE\s/.test(navigator.userAgent) && parseFloat(navigator.appVersion.split("MSIE")[1]) < 10;

        cmd.ExecuteNonQuery();
        cnn.Close();
        return true;
    }
    catch (Exception) {
        return false;
    }
    finally {
        cmd.Dispose();
        cnn = null;
        cmd = null; 
    }
}

Cryptography deals with numbers and strings. Basically every digital thing in the entire universe are numbers. When I say numbers, its 0 & 1. You know what they are, binary. The images you see on screen, the music that you listen through your earphone, everything are binaries. But our ears and eyes will not understand binaries right? Only brain could understand that, and even if it could understand binaries, it can’t enjoy binaries. So we convert the binaries to human understandable formats such as mp3,jpg,etc. Let’s term the process as Encoding. It’s two way process and can be easily decoded back to its original form.

Hashing

Hashing is another cryptography technique in which a data once converted to some other form can never be recovered back. In Layman’s term, there is no process called de-hashing. There are many hash functions to do the job such as sha-512, md5 and so on.

If the original value cannot be recovered, then where do we use this? Passwords! When you set up a password for your mobile or PC, a hash of your password is created and stored in a secure place. When you make a login attempt next time, the entered string is again hashed with the same algorithm (hash function) and the output is matched with the stored value. If it’s the same, you get logged in. Otherwise you are thrown out.

Credits: wikimedia By applying hash to the password, we can ensure that an attacker will never get our password even if he steal the stored password file. The attacker will have the hash of the password. He can probably find a list of most commonly used passwords and apply sha-512 to each of it and compare it with the value in his hand. It is called the dictionary attack. But how long would he do this? If your password is random enough, do you think this method of cracking would work? All the passwords in the databases of Facebook, Google and Amazon are hashed, or at least they are supposed to be hashed.

Then there is Encryption

Encryption lies in between hashing and encoding. Encoding is a two way process and should not be used to provide security. Encryption is also a two way process, but original data can be retrieved if and only if the encryption key is known. If you don’t know how encryption works, don’t worry, we will discuss the basics here. That would be enough to understand the basics of SSL. So, there are two types of Encryption namely Symmetric and Asymmetric encryption.

Symmetric Key Encryption

I am trying to keep things as simple as I could. So, let’s understand the symmetric encryption by means of a shift algorithm. This algorithm is used to encrypt alphabets by shifting the letters to either left or right. Let’s take a string CRYPTO and consider a number +3. Then, the encrypted format of CRYPTO will be FUBSWR. That means each letter is shifted to right by 3 places. Here, the word CRYPTO is called Plaintext, the output FUBSWR is called the Ciphertext, the value +3 is called the Encryption key (symmetric key) and the whole process is a cipher. This is one of the oldest and basic symmetric key encryption algorithm and its first usage was reported during the time of Julius Caesar. So, it was named after him and it is the famous Caesar Cipher. Anyone who knows the encryption key and can apply the reverse of Caesar’s algorithm and retrieve the original Plaintext. Hence it is called a Symmetric Encryption.

Asymmetric Key Encryption

We know that, in Symmetric encryption same key is used for both encryption and decryption. Once that key is stolen, all the data is gone. That’s a huge risk and we need more complex technique. In 1976, Whitfield Diffie and Martin Hellman first published the concept of Asymmetric encryption and the algorithm was known as Diffie–Hellman key exchange. Then in 1978, Ron Rivest, Adi Shamir and Leonard Adleman of MIT published the RSA algorithm. These can be considered as the foundation of Asymmetric cryptography.

As compared to Symmetric encryption, in Asymmetric encryption, there will be two keys instead of one. One is called the Public key, and the other one is the Private key. Theoretically, during initiation we can generate the Public-Private key pair to our machine. Private key should be kept in a safe place and it should never be shared with anyone. Public key, as the name indicates, can be shared with anyone who wish to send encrypted text to you. Now, those who have your public key can encrypt the secret data with it. If the key pair were generated using RSA algorithm, then they should use the same algorithm while encrypting the data. Usually the algorithm will be specified in the public key. The encrypted data can only be decrypted with the private key which is owned by you.

The error is because difference in datatypes of y_pred and y_true. y_true might be dataframe and y_pred is arraylist. If you convert both to arrays, then issue will get resolved.

I do tend to use static classes for factories. For example, this is the logging class in one of my projects:

public static class Log
{
   private static readonly ILoggerFactory _loggerFactory =
      IoC.Resolve<ILoggerFactory>();

   public static ILogger For<T>(T instance)
   {
      return For(typeof(T));
   }

   public static ILogger For(Type type)
   {
      return _loggerFactory.GetLoggerFor(type);
   }
}

You might have even noticed that IoC is called with a static accessor. Most of the time for me, if you can call static methods on a class, that's all you can do so I mark the class as static for extra clarity.

This has to be done during your exe4j configuration. In the fourth step of Exe4j wizard which is Executable Info select> Advanced options select 32-bit or 64-bit. This worked well for me. or else install both JDK tool-kits x64 and x32 in your machine.

Calling conventions defines how parameters are passed in the registers when calling or being called by other program. And the best source of these convention is in the form of ABI standards defined for each these hardware. For ease of compilation, the same ABI is also used by userspace and kernel program. Linux/Freebsd follow the same ABI for x86-64 and another set for 32-bit. But x86-64 ABI for Windows is different from Linux/FreeBSD. And generally ABI does not differentiate system call vs normal "functions calls". Ie, here is a particular example of x86_64 calling conventions and it is the same for both Linux userspace and kernel: http://eli.thegreenplace.net/2011/09/06/stack-frame-layout-on-x86-64/ (note the sequence a,b,c,d,e,f of parameters):

Performance is one of the reasons for these ABI (eg, passing parameters via registers instead of saving into memory stacks)

For ARM there is various ABI:

ARM64 convention:

For Linux on PowerPC:

And for embedded there is the PPC EABI:

This document is good overview of all the different conventions:

I want to add a point that you can also (and should if what you are writing is complex) add a test variable to rollback if you are in test mode. Then you can execute the whole thing at once. Often I also add code to see the before and after results of various operations especially if it is a complex script.

Example below:

USE AdventureWorks;
GO
DECLARE @TEST INT = 1--1 is test mode, use zero when you are ready to execute
BEGIN TRANSACTION;

BEGIN TRY
     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
        END    
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;

     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
            IF @@TRANCOUNT > 0
                ROLLBACK TRANSACTION;
        END    
END TRY

BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0 AND @TEST = 0
    COMMIT TRANSACTION;

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

Here is another alternative using Guava

List<Object> lst ...    
List<String> ls = Lists.transform(lst, Functions.toStringFunction());

Here is an example of iterating over a pd.DataFrame grouped by the column atable. For this sample, "create" statements for an SQL database are generated within the for loop:

import pandas as pd

df1 = pd.DataFrame({
    'atable':     ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
    'column':     ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
    'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
    'is_null':    ['No', 'No', 'Yes', 'No', 'Yes'],
})

df1_grouped = df1.groupby('atable')

# iterate over each group
for group_name, df_group in df1_grouped:
    print('\nCREATE TABLE {}('.format(group_name))

    for row_index, row in df_group.iterrows():
        col = row['column']
        column_type = row['column_type']
        is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
        print('\t{} {} {},'.format(col, column_type, is_null))

    print(");")

On my side it was coming from an error in my settings.xml file. I had a bad tag. Just removed it, refreshed and i was good to go.

I use this code:

bool AlmostEqual(double v1, double v2)
    {
        return (std::fabs(v1 - v2) < std::fabs(std::min(v1, v2)) * std::numeric_limits<double>::epsilon());
    }

When you don't want to write IEqualityComparer you can try something like following.

 class Program
{

    private static void Main(string[] args)
    {

        var items = new List<Item>();
        items.Add(new Item {Id = 1, Name = "Item1"});
        items.Add(new Item {Id = 2, Name = "Item2"});
        items.Add(new Item {Id = 3, Name = "Item3"});

        //Duplicate item
        items.Add(new Item {Id = 4, Name = "Item4"});
        //Duplicate item
        items.Add(new Item {Id = 2, Name = "Item2"});

        items.Add(new Item {Id = 3, Name = "Item3"});

        var res = items.Select(i => new {i.Id, i.Name})
            .Distinct().Select(x => new Item {Id = x.Id, Name = x.Name}).ToList();

        // now res contains distinct records
    }



}


public class Item
{
    public int Id { get; set; }

    public string Name { get; set; }
}

set height: auto; If you want to have minimum height to x then you can write

height:auto;
min-height:30px;
height:auto !important;        /* for IE as it does not support min-height */
height:30px;                   /* for IE as it does not support min-height */

C# is a programming language.

.Net is a framework used for building applications on Windows.

.Net framework is not limited to C#. Different languages can target .Net framework and build applications using that framework. Examples are F# or VB.Net

I think you need to explicitly pass the data attribute. One way to do this is to use the data = $('#your-form-id').serialize();

This post may be helpful. Post with jquery and ajax

The __pycache__ folder and *.pyc files are totally unnecessary to the developer. To hide these files from the explorer view, we need to edit the settings.json for VSCode. Add the folder and the files as shown below:

"files.exclude": {
  ...
  ...
  "**/*.pyc": {"when": "$(basename).py"}, 
  "**/__pycache__": true,
  ...
  ...
}

You can download the needed packages from here and use pip install "Abc.whl" from the directory where you have downloaded the file.

Just write:

private static double balance = 0;

and you could also write those like that:

private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

You can capture a screenshot from Android Studio as shown in the image below.

Sometime we need to compile one single file out of thousand files to fix the problem. In such a case, One can create same folder structure like class path, decompile the file into java or copy java file from source code. Make required changes, compile one particular file into class with all dependency/classes in place and finally replace the class file. Finally restart the container. Once war is exploded file will not be replaced.

I'd like to ask why you are trying to detect when the content of the textbox changed in real time?

An alternative would be to set a timer (via setIntval?) and compare last saved value to the current one and then reset a timer. This would guarantee catching ANY change, whether caused by keys, mouse, some other input device you didn't consider, or even JavaScript changing the value (another possiblity nobody mentioned) from a different part of the app.

oops! just found myself: just add this line on any element you need

   -webkit-appearance: none;

You will need to go to Project->Clean...,then build your project. This will work, even when your source code does not contain any main method to run as an executable program. The .class files will appear in the bin folder of your project, in your workspace.

You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).

Match it against a regular expression.

Re: IsNumeric() clause in MySQL??
Posted by: kevinclark ()
Date: August 08, 2005 01:01PM

I agree. Here is a function I created for MySQL 5:

CREATE FUNCTION IsNumeric (sIn varchar(1024)) RETURNS tinyint
RETURN sIn REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';

This allows for an optional plus/minus sign at the beginning, one optional decimal point, and the rest numeric digits.

I would recommend that start using mysqli_() and stop using mysql_()

Check the following page: LINK

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: mysqli_affected_rows() PDOStatement::rowCount()

Try and use mysqli_() Or PDO

Another possibility is to use regular expressions which is what Perl is famous for:

if ($mystring =~ /s1\.domain\.com/) {
   print qq("$mystring" contains "s1.domain.com"\n);
}

The backslashes are needed because a . can match any character. You can get around this by using the \Q and \E operators.

my $substring = "s1.domain.com";
    if ($mystring =~ /\Q$substring\E/) {
   print qq("$mystring" contains "$substring"\n);
}

Or, you can do as eugene y stated and use the index function. Just a word of warning: Index returns a -1 when it can't find a match instead of an undef or 0.

Thus, this is an error:

my $substring = "s1.domain.com";
if (not index($mystring, $substr)) {
    print qq("$mystring" doesn't contains "$substring"\n";
} 

This will be wrong if s1.domain.com is at the beginning of your string. I've personally been burned on this more than once.

If the source code will not have issues with LF to be replaced by CRLF, No debugging is required by following simple codes outputs.

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;
str = str.replace(regex, "$11$2");
console.log(str);

Or if you're sure there won't be any other digits in the string:

var str   = 'asd-0.testing';
var regex = /\d/;
str = str.replace(regex, "1");
console.log(str);

Deparse tells us this is what is being executed:

$find = 'start (.*) end';
$replace = "foo \cA bar";
$var = 'start middle end';
$var =~ s/$find/$replace/;

However,

 /$find/foo \1 bar/

Is interpreted as :

$var =~ s/$find/foo $1 bar/;

Unfortunately it appears there is no easy way to do this.

You can do it with a string eval, but thats dangerous.

The most sane solution that works for me was this:

$find = "start (.*) end"; 
$replace = 'foo \1 bar';

$var = "start middle end"; 

sub repl { 
    my $find = shift; 
    my $replace = shift; 
    my $var = shift;

    # Capture first 
    my @items = ( $var =~ $find ); 
    $var =~ s/$find/$replace/; 
    for( reverse 0 .. $#items ){ 
        my $n = $_ + 1; 
        #  Many More Rules can go here, ie: \g matchers  and \{ } 
        $var =~ s/\\$n/${items[$_]}/g ;
        $var =~ s/\$$n/${items[$_]}/g ;
    }
    return $var; 
}

print repl $find, $replace, $var; 

A rebuttal against the ee technique:

As I said in my answer, I avoid evals for a reason.

$find="start (.*) end";
$replace='do{ print "I am a dirty little hacker" while 1; "foo $1 bar" }';

$var = "start middle end";
$var =~ s/$find/$replace/ee;

print "var: $var\n";

this code does exactly what you think it does.

If your substitution string is in a web application, you just opened the door to arbitrary code execution.

Good Job.

Also, it WON'T work with taints turned on for this very reason.

$find="start (.*) end";
$replace='"' . $ARGV[0] . '"';

$var = "start middle end";
$var =~ s/$find/$replace/ee;

print "var: $var\n"


$ perl /tmp/re.pl  'foo $1 bar'
var: foo middle bar
$ perl -T /tmp/re.pl 'foo $1 bar' 
Insecure dependency in eval while running with -T switch at /tmp/re.pl line 10.

However, the more careful technique is sane, safe, secure, and doesn't fail taint. ( Be assured tho, the string it emits is still tainted, so you don't lose any security. )

1800 INFORMATION is more or less correct, but there are a few issues I wanted to correct.

boost::shared_mutex _access;
void reader()
{
  boost::shared_lock< boost::shared_mutex > lock(_access);
  // do work here, without anyone having exclusive access
}

void conditional_writer()
{
  boost::upgrade_lock< boost::shared_mutex > lock(_access);
  // do work here, without anyone having exclusive access

  if (something) {
    boost::upgrade_to_unique_lock< boost::shared_mutex > uniqueLock(lock);
    // do work here, but now you have exclusive access
  }

  // do more work here, without anyone having exclusive access
}

void unconditional_writer()
{
  boost::unique_lock< boost::shared_mutex > lock(_access);
  // do work here, with exclusive access
}

Also Note, unlike a shared_lock, only a single thread can acquire an upgrade_lock at one time, even when it isn't upgraded (which I thought was awkward when I ran into it). So, if all your readers are conditional writers, you need to find another solution.

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

Short answer:

ALTER SCHEMA new_schema TRANSFER old_schema.table_name

I can confirm that the data in the table remains intact, which is probably quite important :)

Long answer as per MSDN docs,

ALTER SCHEMA schema_name 
   TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]

If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.

It's perfect time to try zsh, an (almost) bash superset, with many additional nice features including floating point math. Here is what your example would be like in zsh:

% IMG_WIDTH=1080
% IMG2_WIDTH=640
% result=$((IMG_WIDTH*1.0/IMG2_WIDTH))
% echo $result
1.6875

This post may help you: bash - Worth switching to zsh for casual use?

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

Your declaration is int ttTreeInsert(int value);

However, your definition/implementation is

ttTree::ttTreeInsert(int value)
{
}

Notice that the return type int is missing in the implementation. Instead it should be

int ttTree::ttTreeInsert(int value)
{
    return 1; // or some valid int
}

You can union the queries as long as the columns match.

SELECT name,
       games,
       goals
FROM   tblMadrid
WHERE  id = 1
UNION ALL
SELECT name,
       games,
       goals
FROM   tblBarcelona
WHERE  id = 2 

Unfortunately, there is no guaranteed way to do it at time of selection.

Some browsers support the accept attribute for input tags. This is a good start, but cannot be relied upon completely.

<input type="file" name="pic" id="pic" accept="image/gif, image/jpeg" />

You can use a cfinput and run a validation to check the file extension at submission, but not the mime-type. This is better, but still not fool-proof. Files on OSX often have no file extensions or users could maliciously mislabel the file types.

ColdFusion's cffile can check the mime-type using the contentType property of the result (cffile.contentType), but that can only be done after the upload. This is your best bet, but is still not 100% safe as mime-types could still be wrong.

Try to set

this.MinimumSize = new Size(140, 480);
this.MaximumSize = new Size(140, 480);

try doing str.replace(/[^\w]/); It will replace all the non-alphabets and numbers from your string!

Edit 1: str.replace(/[^\w]/g, ' ')

It will be increasing because you have a need for temporary storage space, possibly due to a cartesian product or a large sort operation.

The dynamic performance view V$TEMPSEG_USAGE will help diagnose the cause.

    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Iterate through the last row and populate it with the entries from values()
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(NewData) + 1 Then lastRow.Cells(1, col) = NewData(col - 1)
    Next col
End Sub

New Data in Horizontal Range:

Sub AddDataRow(tableName As String, NewData As Range)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last table row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Copy NewData to new table record
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    lastRow.Value = NewData.Value
End Sub

Try this:

(select * from T1 minus select * from T2) -- all rows that are in T1 but not in T2
union all
(select * from T2 minus select * from T1)  -- all rows that are in T2 but not in T1
;

No external tool. No performance issues with union all.

I prefer not to check session variable in code instead use FormAuthentication. They have inbuilt functionlity to redirect to given LoginPage specified in web.config.

However if you want to explicitly check the session you can check for NULL value for any of the variable you created in session earlier as Pranay answered.

You can create Login.aspx page and write your message there , when session expires FormAuthentication automatically redirect to loginUrl given in FormAuthentication section

<authentication mode="Forms">
  <forms loginUrl="Login.aspx" protection="All" timeout="30">
  </forms>
</authentication>

The thing is that you can't give seperate page for Login and SessionExpire , so you have to show/hide some section on Login.aspx to act it both ways.

There is another way to redirect to sessionexpire page after timeout without changing formauthentication->loginurl , see the below link for this : http://www.schnieds.com/2009/07/aspnet-session-expiration-redirect.html

I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange!

Say, for example, that you have a number of websites that use the same PayPal account to handle your payments, or say that you have a number of sections in one website that perform different purchasing tasks, and require different return-addresses when the payment is completed. If I put a button on my page as described above in the 'Sample form using PHP for direct payments' section, you can see that there is a line there:

input type="hidden" name="return" value="https://www.yoursite.com/checkout_complete.php"

where you set the individual return value. Why does it have to be set generally, in the profile section as well?!?!

Also, because you can only set one value in the Profile Section, it means (AFAIK) that you cannot use the Auto Return on a site with multiple actions.

Comments please??

Use arbitrary, extensible object, and then serialize it to JSON:

import json

class Object(object):
    pass

response = Object()
response.debug = []
response.result = Object()

# Any manipulations with the object:
response.debug.append("Debug string here")
response.result.body = "404 Not Found"
response.result.code = 404

# Proper JSON output, with nice formatting:
print(json.dumps(response, indent=4, default=lambda x: x.__dict__))

Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used

This is what I did:

1. Change project and solution name in Visual Studio
2. Close the project and open the folder containing the project (The Visual studio solution name is already changed).
3. Change the old project folder names to the new project name
4. Open the .sln file and the change the project folder names manually from old to new folder names.
5. Save the .sln file in the text editor
6. Open the project again with Visual Studio and the solution is ready to modify

When you create an initialization of the ResourceBundle, you can do this way also.

For testing and development I have created a properties file under \src with the name prp.properties.

Use this way:

ResourceBundle rb = ResourceBundle.getBundle("prp");

Naming convention and stuff:

I've figure it out the solution to my problem:

• Step 1: from within the vSphere client, while connected to vCenter1, select the VM and then from "File" menu select "Export"->"Export OVF Template" (Note: make sure the VM is Powered Off otherwise this feature is not available - it will be gray). This action will allow you to save on your machine/laptop the VM (as an .vmdk, .ovf and a .mf file).
• Step 2: Connect to the vCenter2 with your vSphere client and from "File" menu select "Deploy OVF Template..." and then select the location where the VM was saved in the previous step.

That was all!
Thanks!

Below function allow to groupBy (and sum values - what OP need) of arbitrary fields. In solution we define cmp function to compare two object according to grouped fields. In let w=... we create copy of subset object x fields. In y[sumBy]=+y[sumBy]+(+x[sumBy]) we use '+' to cast string to number.

function groupBy(data, fields, sumBy='Value') {
  let r=[], cmp= (x,y) => fields.reduce((a,b)=> a && x[b]==y[b], true);
  data.forEach(x=> {
    let y=r.find(z=>cmp(x,z));
    let w= [...fields,sumBy].reduce((a,b) => (a[b]=x[b],a), {})
    y ? y[sumBy]=+y[sumBy]+(+x[sumBy]) : r.push(w);
  });
  return r;

If you go thru this IBM link on java, it says that on 32 bit windows the recommended heap size is 1.5 GB and the Maximum heap size is 1.8 GB. So your jvm does not gets initialized for -Xmx2G and above.

Also if you go thru this SO answer, clearly the DLL bindings are an issue for memory reservation changing which is no trivial task. Hence what may be recommended is that you go for 64-bit Windows and a 64-bit JVM. while it will chew up more RAM, you will have much more contiguous virtual address space.

This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

var mytextvalue = document.getElementById("mytext").value;
console.log(mytextvalue == ''); // true
console.log(mytextvalue == null); // false

and changing the console.log to alert, I still get the desired output in IE6.

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

Put the date in single quotes and move the parenthesis (after the 'yes') to the end:

INSERT INTO custorder 
  VALUES ('Kevin', 'yes' , STR_TO_DATE('1-01-2012', '%d-%m-%Y') ) ;
                        ^                                     ^
---parenthesis removed--|                and added here ------|

But you can always use dates without STR_TO_DATE() function, just use the (Y-m-d) '20120101' or '2012-01-01' format. Check the MySQL docs: Date and Time Literals

INSERT INTO custorder 
  VALUES ('Kevin', 'yes', '2012-01-01') ;

Some "front ends", with the "Use Booleans" option enabled, will treat all TINYINT(1) columns as Boolean, and vice versa.

This allows you to, in the application, use TRUE and FALSE rather than 1 and 0.

This doesn't affect the database at all, since it's implemented in the application.

There is not really a BOOLEAN type in MySQL. BOOLEAN is just a synonym for TINYINT(1), and TRUE and FALSE are synonyms for 1 and 0.

If the conversion is done in the compiler, there will be no difference in performance in the application. Otherwise, the difference still won't be noticeable.

You should use whichever method allows you to code more efficiently, though not using the feature may reduce dependency on that particular "front end" vendor.

In Java:

package somepackage;
class SomeClass {}

In C++:

namespace somenamespace {
    class SomeClass {}
}

And using them, Java:

import somepackage;

And C++:

using namespace somenamespace;

Also, full names are "somepackge.SomeClass" for Java and "somenamespace::SomeClass" for C++. Using those conventions, you can organize like you are used to in Java, including making matching folder names for namespaces. The folder->package and file->class requirements aren't there though, so you can name your folders and classes independently off packages and namespaces.

Ref and event bus both has issues when your control render is affected by v-if. So, I decided to go with a simpler method.

The idea is using an array as a queue to send methods that needs to be called to the child component. Once the component got mounted, it will process this queue. It watches the queue to execute new methods.

(Borrowing some code from Desmond Lua's answer)

Parent component code:

import ChildComponent from './components/ChildComponent'

new Vue({
  el: '#app',
  data: {
    item: {},
    childMethodsQueue: [],
  },
  template: `
  <div>
     <ChildComponent :item="item" :methods-queue="childMethodsQueue" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.childMethodsQueue.push({name: ChildComponent.methods.save.name, params: {}})
    }
  },
  components: { ChildComponent },
})

This is code for ChildComponent

<template>
 ...
</template>

<script>
export default {
  name: 'ChildComponent',
  props: {
    methodsQueue: { type: Array },
  },
  watch: {
    methodsQueue: function () {
      this.processMethodsQueue()
    },
  },
  mounted() {
    this.processMethodsQueue()
  },
  methods: {
    save() {
        console.log("Child saved...")
    },
    processMethodsQueue() {
      if (!this.methodsQueue) return
      let len = this.methodsQueue.length
      for (let i = 0; i < len; i++) {
        let method = this.methodsQueue.shift()
        this[method.name](method.params)
      }
    },
  },
}
</script>

And there is a lot of room for improvement like moving processMethodsQueue to a mixin...

LD_LIBRARY_PATH is Linux specific and is an environment variable pointing to directories where the dynamic loader should look for shared libraries.

Try to add the directory where your .dll is in the PATH variable. Windows will automatically look in the directories listet in this environment variable. LD_LIBRARY_PATH probably won't solve the problem (unless the JVM uses it - I do not know about that).

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

thanks to @??s???? K and Terry ... it helps me a lot and works perfectly

From Activity you send data with intent as:

Bundle bundle = new Bundle(); 
bundle.putString("edttext", "From Activity"); 
// set Fragmentclass Arguments
Fragmentclass fragobj = new Fragmentclass();
fragobj.setArguments(bundle);

and in Fragment onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // get arguments
    String strtext = getArguments().getString("edttext");    
    return inflater.inflate(R.layout.fragment, container, false);
}

Just had the same issue, for those having the same one it may be that you put the library on the modulepath rather than the classpath while adding it to your project

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.

There are two ways to interpret the input data; either -128 is the lowest value, and 127 is the highest (i.e. true signed data), or 0 is the lowest value, 127 is somewhere in the middle, and the next "higher" number is -128, with -1 being the "highest" value (that is, the most significant bit already got misinterpreted as a sign bit in a two's complement notation.

Assuming you mean the latter, the formally correct way is

signed char in = ...
unsigned char out = (in < 0)?(in + 256):in;

which at least gcc properly recognizes as a no-op.

X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

You can use native javascript function

var obj = {a:1,b:2};

Object.keys(obj).forEach(function(key){
    console.log(key, obj[el])
})

or create an object prototype foreach, but it usually causes issues with other frameworks

if (!Object.prototype.forEach) {
  Object.defineProperty(Object.prototype, 'forEach', {
    value: function (callback, thisArg) {
      if (this == null) {
        throw new TypeError('Not an object');
      }
      thisArg = thisArg || window;
      for (var key in this) {
        if (this.hasOwnProperty(key)) {
          callback.call(thisArg, this[key], key, this);
        }
      }
    }
  });
}

var obj = {a:1,b:2};

obj.forEach(function(key, value){
    console.log(key, value)
})

In Kotlin we can get application context in fragment using this

requireActivity().application

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:

import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()

In your solution

from matplotlib import*

This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as

from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()

Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.

I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()

In addition to the answers here you might want to make sure that the documentation is downloaded. To do that go to SDK Manager

and then the SDK Tools tab and make sure Documentation for Android SDK is installed.

If it isn't check the box and click Apply.

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

This boils down to two distinct steps:

1. Figure out when your condition is true, and hence compute a vector of booleans, or, as I prefer, their indices by wrapping it into which()
2. Create an updated data.frame by excluding the indices from the previous step.

Here is an example:

R> set.seed(42)
R> DF <- data.frame(sub=rep(1:4, each=4), day=sample(1:4, 16, replace=TRUE))
R> DF
   sub day
1    1   4
2    1   4
3    1   2
4    1   4
5    2   3
6    2   3
7    2   3
8    2   1
9    3   3
10   3   3
11   3   2
12   3   3
13   4   4
14   4   2
15   4   2
16   4   4
R> ind <- which(with( DF, sub==2 & day==3 ))
R> ind
[1] 5 6 7
R> DF <- DF[ -ind, ]
R> table(DF)
   day
sub 1 2 3 4
  1 0 1 0 3
  2 1 0 0 0
  3 0 1 3 0
  4 0 2 0 2
R> 

And we see that sub==2 has only one entry remaining with day==1.

Edit The compound condition can be done with an 'or' as follows:

ind <- which(with( DF, (sub==1 & day==2) | (sub=3 & day=4) ))

and here is a new full example

R> set.seed(1)
R> DF <- data.frame(sub=rep(1:4, each=5), day=sample(1:4, 20, replace=TRUE))
R> table(DF)
   day
sub 1 2 3 4
  1 1 2 1 1
  2 1 0 2 2
  3 2 1 1 1
  4 0 2 1 2
R> ind <- which(with( DF, (sub==1 & day==2) | (sub==3 & day==4) ))
R> ind
[1]  1  2 15
R> DF <- DF[-ind, ]
R> table(DF)
   day
sub 1 2 3 4
  1 1 0 1 1
  2 1 0 2 2
  3 2 1 1 0
  4 0 2 1 2

I was just trying to fix same error, I finally fixed it, so I will copy to you part of the code, maybe it helps you.

<input type="text" name="usu" id="usu" value="<?php echo $usu;?>" ></input>
<input type="text" name="pass" id="pass" value="<?php echo $varpass;?>"></input>  

those are the inputs I wanted to clean after pressing my button.

And here php code:

$query= "INSERT INTO usuarios (tipo, usuario, password) VALUES ('".$vartipo."', '".$usu."', '".$varpass."')";


        if (!mysqli_query($conexion,$query)){

            die('Error: ' . mysqli_error($conexion));
        }

        else{


            $usu = '';  
            $varpass= '';   

            $result = '<div class="result_ok">El usuario se ha registrado con éxito! <div>';        


        }

$usu = '';
$varpass= '';

those are the lines that cleans the inputs :D

from Jackson 2.7.x+ there is a way to annotate the member variable itself:

 @JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY)
 private List<String> newsletters;

More info here: Jackson @JsonFormat

We can make transparent in dis way also.

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

None of the above worked for me.

Here's my solution- works great:

$dropTarget.droppable({
    drop: function( event, ui ) {

    // Get mouse position relative to drop target: 
    var dropPositionX = event.pageX - $(this).offset().left;
    var dropPositionY = event.pageY - $(this).offset().top;
    // Get mouse offset relative to dragged item:
    var dragItemOffsetX = event.offsetX;
    var dragItemOffsetY = event.offsetY;
    // Get position of dragged item relative to drop target:
    var dragItemPositionX = dropPositionX-dragItemOffsetX;
    var dragItemPositionY = dropPositionY-dragItemOffsetY;

    alert('DROPPED IT AT ' + dragItemPositionX + ', ' + dragItemPositionY);
