I would say remove them and define a default: branch.

I believe the accepted answer should be: android:background="?attr/selectableItemBackground"

This is the same as @lory105's answer but it uses the support library for maximum compatibility (the android: equivalent is only available for API >= 11)

public boolean equals(Object o) {
        if (o == this)
            return true;
        if (!(o instanceof Set))
            return false;

        Set<String> a = this;
        Set<String> b = o;
        Set<String> thedifference_a_b = new HashSet<String>(a);


        thedifference_a_b.removeAll(b);
        if(thedifference_a_b.isEmpty() == false) return false;

        Set<String> thedifference_b_a = new HashSet<String>(b);
        thedifference_b_a.removeAll(a);

        if(thedifference_b_a.isEmpty() == false) return false;

        return true;
    }

To complement the preexisting, helpful answers with guidance of when to use which approach and a performance comparison.

• Outside of a pipeline^[1], use (PSv3+):

  $objects.Name

  as demonstrated in rageandqq's answer, which is both syntactically simpler and much faster.

  • Accessing a property at the collection level to get its members' values as an array is called member enumeration and is a PSv3+ feature.

  • Alternatively, in PSv2, use the foreach statement, whose output you can also assign directly to a variable:

    $results = foreach ($obj in $objects) { $obj.Name }

  • If collecting all output from a (pipeline) command in memory first is feasible, you can also combine pipelines with member enumeration; e.g.:

     (Get-ChildItem -File | Where-Object Length -lt 1gb).Name
    

  • Tradeoffs:

    • Both the input collection and output array must fit into memory as a whole.
    • If the input collection is itself the result of a command (pipeline) (e.g., (Get-ChildItem).Name), that command must first run to completion before the resulting array's elements can be accessed.

• In a pipeline, in case you must pass the results to another command, notably if the original input doesn't fit into memory as a whole, use:

  $objects | Select-Object -ExpandProperty Name

  • The need for -ExpandProperty is explained in Scott Saad's answer (you need it to get only the property value).
  • You get the usual pipeline benefits of the pipeline's streaming behavior, i.e. one-by-one object processing, which typically produces output right away and keeps memory use constant (unless you ultimately collect the results in memory anyway).
  • Tradeoff:
    • Use of the pipeline is comparatively slow.

For small input collections (arrays), you probably won't notice the difference, and, especially on the command line, sometimes being able to type the command easily is more important.

Here is an easy-to-type alternative, which, however is the slowest approach; it uses simplified ForEach-Object syntax called an operation statement (again, PSv3+): ; e.g., the following PSv3+ solution is easy to append to an existing command:

$objects | % Name      # short for: $objects | ForEach-Object -Process { $_.Name }

The PSv4+ .ForEach() array method, more comprehensively discussed in this article, is yet another, well-performing alternative, but note that it requires collecting all input in memory first, just like member enumeration:

# By property name (string):
$objects.ForEach('Name')

# By script block (more flexibility; like ForEach-Object)
$objects.ForEach({ $_.Name })

• This approach is similar to member enumeration, with the same tradeoffs, except that pipeline logic is not applied; it is marginally slower than member enumeration, though still noticeably faster than the pipeline.

• For extracting a single property value by name (string argument), this solution is on par with member enumeration (though the latter is syntactically simpler).

• The script-block variant ({ ... }) allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).

Note: The .ForEach() array method, like its .Where() sibling (the in-memory equivalent of Where-Object), always returns a collection (an instance of [System.Collections.ObjectModel.Collection[psobject]]), even if only one output object is produced.
By contrast, member enumeration, Select-Object, ForEach-Object and Where-Object return a single output object as-is, without wrapping it in a collection (array).

Comparing the performance of the various approaches

Here are sample timings for the various approaches, based on an input collection of 10,000 objects, averaged across 10 runs; the absolute numbers aren't important and vary based on many factors, but it should give you a sense of relative performance (the timings come from a single-core Windows 10 VM:

Important

• The relative performance varies based on whether the input objects are instances of regular .NET Types (e.g., as output by Get-ChildItem) or [pscustomobject] instances (e.g., as output by Convert-FromCsv).
  The reason is that [pscustomobject] properties are dynamically managed by PowerShell, and it can access them more quickly than the regular properties of a (statically defined) regular .NET type. Both scenarios are covered below.

• The tests use already-in-memory-in-full collections as input, so as to focus on the pure property extraction performance. With a streaming cmdlet / function call as the input, performance differences will generally be much less pronounced, as the time spent inside that call may account for the majority of the time spent.

• For brevity, alias % is used for the ForEach-Object cmdlet.

General conclusions, applicable to both regular .NET type and [pscustomobject] input:

• The member-enumeration ($collection.Name) and foreach ($obj in $collection) solutions are by far the fastest, by a factor of 10 or more faster than the fastest pipeline-based solution.

• Surprisingly, % Name performs much worse than % { $_.Name } - see this GitHub issue.

• PowerShell Core consistently outperforms Windows Powershell here.

Conclusions:

• In PowerShell Core, .ForEach('Name') clearly outperforms .ForEach({ $_.Name }). In Windows PowerShell, curiously, the latter is faster, albeit only marginally so.

Conclusions:

• Note how with [pscustomobject] input .ForEach('Name') by far outperforms the script-block based variant, .ForEach({ $_.Name }).

• Similarly, [pscustomobject] input makes the pipeline-based Select-Object -ExpandProperty Name faster, in Windows PowerShell virtually on par with .ForEach({ $_.Name }), but in PowerShell Core still about 50% slower.

• In short: With the odd exception of % Name, with [pscustomobject] the string-based methods of referencing the properties outperform the scriptblock-based ones.

^{[1] Technically, even a command without |, the pipeline operator, uses a pipeline behind the scenes, but for the purpose of this discussion using the pipeline refers only to commands that do use | and therefore involve multiple commands connected by a pipeline.}

In bash for string comparison, you can use the following technique.

if [ $var OP "val" ]; then
    echo "statements"
fi

Example:

var="something"
if [ $var != "otherthing" ] && [ $var != "everything" ] && [ $var != "allthings" ]; then
    echo "this will be printed"
else
    echo "this will not be printed"
fi

In code, you need to explicitly create a Brush instance:

Fill = new SolidColorBrush(Color.FromArgb(0xff, 0xff, 0x90))

I had the same issue and it was caused by being unable to connect to the database instance. Look for hibernate error HHH000342 in the log above that error, it should give you an idea to where the db connection is failing (incorrect username/pass, url, etc.)

You have to put a g at the end, it stands for "global":

echo dog dog dos | sed -r 's:dog:log:g'
                                     ^

It can be done with simple Makefile:

sleep%:
        sleep $(subst sleep,,$@)
        @echo $@ done.

Use -j option.

$ make -j sleep3 sleep2 sleep1
sleep 3
sleep 2
sleep 1
sleep1 done.
sleep2 done.
sleep3 done.

Without -j option it executes in serial.

$ make -j sleep3 sleep2 sleep1
sleep 3
sleep3 done.
sleep 2
sleep2 done.
sleep 1
sleep1 done.

You can also do dry run with `-n' option.

$ make -j -n sleep3 sleep2 sleep1
sleep 3
sleep 2
sleep 1

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

Remove -ObjC from Other Linker Flags or Please check you imported any .m file instead of .h by mistake.

With Bootstrap 4 .hidden-* classes were completely removed (yes, they were replaced by hidden-*-* but those classes are also gone from v4 alphas).

Starting with v4-beta, you can combine .d-*-none and .d-*-block classes to achieve the same result.

visible-* was removed as well; instead of using explicit .visible-* classes, make the element visible by not hiding it (again, use combinations of .d-none .d-md-block). Here is the working example:

<div class="col d-none d-sm-block">
    <span class="vcard">
        …
    </span>
</div>
<div class="col d-none d-xl-block">
    <div class="d-none d-md-block">
                …
    </div>
    <div class="d-none d-sm-block">
                …
    </div>
</div>

class="hidden-xs" becomes class="d-none d-sm-block" (or d-none d-sm-inline-block) ...

<span class="d-none d-sm-inline">hidden-xs</span>

<span class="d-none d-sm-inline-block">hidden-xs</span>

An example of Bootstrap 4 responsive utilities:

<div class="d-none d-sm-block"> hidden-xs           
  <div class="d-none d-md-block"> visible-md and up (hidden-sm and down)
    <div class="d-none d-lg-block"> visible-lg and up  (hidden-md and down)
      <div class="d-none d-xl-block"> visible-xl </div>
    </div>
  </div>
</div>

<div class="d-sm-none"> eXtra Small <576px </div>
<div class="d-none d-sm-block d-md-none d-lg-none d-xl-none"> SMall =576px </div>
<div class="d-none d-md-block d-lg-none d-xl-none"> MeDium =768px </div>

Suppose you have a timedelta series:

import pandas as pd
from datetime import datetime
z = pd.DataFrame({'a':[datetime.strptime('20150101', '%Y%m%d')],'b':[datetime.strptime('20140601', '%Y%m%d')]})

td_series = (z['a'] - z['b'])

One way to convert this timedelta column or series is to cast it to a Timedelta object (pandas 0.15.0+) and then extract the days from the object:

td_series.astype(pd.Timedelta).apply(lambda l: l.days)

Another way is to cast the series as a timedelta64 in days, and then cast it as an int:

td_series.astype('timedelta64[D]').astype(int)

Thread t1 = new Thread(new Runnable() {
    @Override

new Thread(new Runnable() {
     @Override
     public void run() {
          // code goes here.
     }
}).start();

or

new Thread(() -> {

        myCustomMethod();
    }

    @Override
    public void run() {
        myCustomMethod();
    }
});

List<string> empnames = (from e in emplist select e.Enaame).ToList();

Or

string[] empnames = (from e in emplist select e.Enaame).ToArray();

Etc...

You can use list ?? Enumerable.Empty<Friend>(), or have FindFriends return Enumerable.Empty<Friend>()

Try this:

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

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

I had the same problem but also listed in the error log was this: CSSMERR_TP_CERT_NOT_VALID_YET

Looking at the certificate in KeyChain showed a similar message. The problem was due to my Mac's system clock being set incorrectly. As soon as I set the correct region/time, the certificate was marked as valid and I could build and run my app on the iPhone

In /System/Library/Frameworks/JavaVM.framework/Versions you'll see all the installed JDKs. There is a symbolic link named CurrentJDK pointing the active JDK.

Adding to the above mentioned benefits of swap(). That clear() does not guarantee deallocation of memory. You can use swap() as follows:

std::vector<T>().swap(myvector);

If you’re trying to delete a very large number of files at one time (I deleted a directory with 485,000+ today), you will probably run into this error:

/bin/rm: Argument list too long.

The problem is that when you type something like rm -rf *, the * is replaced with a list of every matching file, like “rm -rf file1 file2 file3 file4” and so on. There is a relatively small buffer of memory allocated to storing this list of arguments and if it is filled up, the shell will not execute the program.

To get around this problem, a lot of people will use the find command to find every file and pass them one-by-one to the “rm” command like this:

find . -type f -exec rm -v {} \;

My problem is that I needed to delete 500,000 files and it was taking way too long.

I stumbled upon a much faster way of deleting files – the “find” command has a “-delete” flag built right in! Here’s what I ended up using:

find . -type f -delete

Using this method, I was deleting files at a rate of about 2000 files/second – much faster!

You can also show the filenames as you’re deleting them:

find . -type f -print -delete

…or even show how many files will be deleted, then time how long it takes to delete them:

root@devel# ls -1 | wc -l && time find . -type f -delete
100000
real    0m3.660s
user    0m0.036s
sys     0m0.552s

Keep a reference to the timer somewhere, and use:

timer.cancel();
timer.purge();

to stop whatever it's doing. You could put this code inside the task you're performing with a static int to count the number of times you've gone around, e.g.

private static int count = 0;
public static void run() {
     count++;
     if (count >= 6) {
         timer.cancel();
         timer.purge();
         return;
     }

     ... perform task here ....

}

In most cases you want simple ArrayList - an implementation of List

Before JDK version 7

List<String> list = new ArrayList<String>();

JDK 7 and later you can use the diamond operator

List<String> list = new ArrayList<>();

I am running CentOS 5.6 as my development environment and the following worked for me.

You can set the ReadOnly property to true.

Quoth the link:

When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.

Change it to:

  std::string s;
  std::string* pS = &s;
  myfunc(pS);

EDIT:

This is called ref-to-pointer and you cannot pass temporary address as a reference to function. ( unless it is const reference).

Though, I have shown std::string* pS = &s; (pointer to a local variable), its typical usage would be : when you want the callee to change the pointer itself, not the object to which it points. For example, a function that allocates memory and assigns the address of the memory block it allocated to its argument must take a reference to a pointer, or a pointer to pointer:

void myfunc(string*& val)
{
//val is valid even after function call
   val = new std::string("Test");

}

I would use the Underscore.js library that has a list of useful functions.

without

without_.without(array, *values)

Returns a copy of the array with all instances of the values removed.

_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);
// => [2, 3, 4]

Example

var res = "deleteMe";

$scope.nodes = [
  {
    name: "Node-1-1"
  },
  {
    name: "Node-1-2"
  },
  {
    name: "deleteMe"
  }
];
    
$scope.newNodes = _.without($scope.nodes, _.findWhere($scope.nodes, {
  name: res
}));

See Demo in JSFiddle.

filter

var evens = _.filter([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });

// => [2, 4, 6]

Example

$scope.newNodes = _.filter($scope.nodes, function(node) {
  return !(node.name == res);
});

See Demo in Fiddle.

Consider the following simple Python script:

import time
import sys

for i in range(5):
    print(i),
    #sys.stdout.flush()
    time.sleep(1)

This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not see any output until the script completes, and then all at once you will see 0 1 2 3 4 printed to the screen.

This is because the output is being buffered, and unless you flush sys.stdout after each print you won't see the output immediately. Remove the comment from the sys.stdout.flush() line to see the difference.

When the JVM loads classes, or otherwise sees a literal string, or some code interns a string, it adds the string to a mostly-hidden lookup table that has one copy of each such string. If another copy is added, the runtime arranges it so that all the literals refer to the same string object. This is called "interning". If you say something like

String s = "test";
return (s == "test");

it'll return true, because the first and second "test" are actually the same object. Comparing interned strings this way can be much, much faster than String.equals, as there's a single reference comparison rather than a bunch of char comparisons.

You can add a string to the pool by calling String.intern(), which will give you back the pooled version of the string (which could be the same string you're interning, but you'd be crazy to rely on that -- you often can't be sure exactly what code has been loaded and run up til now and interned the same string). The pooled version (the string returned from intern) will be equal to any identical literal. For example:

String s1 = "test";
String s2 = new String("test");  // "new String" guarantees a different object

System.out.println(s1 == s2);  // should print "false"

s2 = s2.intern();
System.out.println(s1 == s2);  // should print "true"

I'm not sure, but I think the second parameter is a red herring.

Both .Rows and .Columns take two optional parameters: RowIndex and ColumnIndex. Try to use ColumnIndex, e.g. Rows(ColumnIndex:=2), generates an error for both .Rows and .Columns.

My feeling it's inherited in some sense from the Cells(RowIndex,ColumnIndex) Property but only the first parameter is appropriate.

You can simply do this

$data += array($category => $question);

If your're running on php 5.4+

$data += [$category => $question];

This is in the feature backlog for Compose but it doesn't look like work has been started yet. Github issue.

my friend by this u are not getting height of image stored in db.but you are getting view height.for getting height of image u have to create bitmap from db,s image.and than u can fetch height and width of imageview

If none of the other options works, then this could be an issue with the version of the JDK itself, just uninstall the current jdk and install the latest version.

I too faced this issue, after trying everything I upgraded to latest JDK, then this issue was resolved finally.

There are two totally conflicting answers with large number of votes one is 160px@1024 the other is 180px@1024. So witch one?

I ran some experiments and I think that it is 180px@1024 so drbarnard is correct.

I downloaded iTunes U icon from the App Store it's 175x175px I upscaled it in photoshop to 1024px and put two shapes on it, one with 160px radius and one with 180px.

As you can see below the shape (thin gray line) with 160px (the 1st one) is a bit off whereas the one with 180px looks just fine.

This is what I do now in PhotoShop:

1. I create a canvas sized 1026x1026px with a 180px mask for main design Smart Object.
2. I duplicate the main Smart Object 5 times and resize them to 1024px, 144px, 114px, 72px and 57px.
3. I put a "New layered Based Slice" on each Smart Objects and I rename slices according to their size (e.g. icon-72px).
4. When I save the artwork I select "All User Slices" and BANG! I have all icons necessary for my app.

If you don't want to use the standard dictionary method (looping through the list incrementing the proper dict. key), you can try this:

>>> from itertools import groupby
>>> myList = words.split() # ['apple', 'banana', 'apple', 'strawberry', 'banana', 'lemon']
>>> [(k, len(list(g))) for k, g in groupby(sorted(myList))]
[('apple', 2), ('banana', 2), ('lemon', 1), ('strawberry', 1)]

It runs in O(n log n) time.

I know this is an old post, but figured I'd share my two cents. @Neji is correct in that you can use sessionStorage.getItem('label'), and sessionStorage.setItem('label', 'value') (although he had the setItem parameters backwards, not a big deal). I much more prefer the following, I think it's more succinct:

var val = sessionStorage.myValue

in place of getItem and

sessionStorage.myValue = 'value'

in place of setItem.

Also, it should be noted that in order to store JavaScript objects, they must be stringified to set them, and parsed to get them, like so:

sessionStorage.myObject = JSON.stringify(myObject); //will set object to the stringified myObject
var myObject = JSON.parse(sessionStorage.myObject); //will parse JSON string back to object

The reason is that sessionStorage stores everything as a string, so if you just say sessionStorage.object = myObject all you get is [object Object], which doesn't help you too much.

I implemented this in the following way after receiving a NullPointerException from the accepted answer.

In my FXML:

<Button onMouseClicked="#onMouseClickedCancelBtn" text="Cancel">

In my Controller class:

@FXML public void onMouseClickedCancelBtn(InputEvent e) {
    final Node source = (Node) e.getSource();
    final Stage stage = (Stage) source.getScene().getWindow();
    stage.close();
}

I personally didn't find any of these answers helpful. What worked in my case was giving the element float:none and position:relative. After that the element centered itself in the <td>.

There is too much data to be displayed on the screen, therefore a summary is displayed instead.

If you want to output the data anyway (it won't probably fit on a screen and does not look very well):

print paramdata.values

converts the dataframe to its numpy-array matrix representation.

paramdata.columns

stores the respective column names and

paramdata.index

stores the respective index (row names).

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

I know this is an old question, but I've found another answer that worked better for me and it doesn't seem to appear in any of the answers.

Create a layout xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="5dip"
    android:paddingBottom="5dip"
    android:paddingStart="10dip"
    android:paddingEnd="10dip">

<ImageView
    android:id="@+id/shoe_select_icon"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_gravity="center_vertical"
    android:scaleType="fitXY" />

<TextView
    android:id="@+id/shoe_select_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:textSize="20sp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"/>

</LinearLayout>

Create a ListPopupWindow and a map with the content:

ListPopupWindow popupWindow;
List<HashMap<String, Object>> data = new ArrayList<>();
HashMap<String, Object> map = new HashMap<>();
    map.put(TITLE, getString(R.string.left));
    map.put(ICON, R.drawable.left);
    data.add(map);
    map = new HashMap<>();
    map.put(TITLE, getString(R.string.right));
    map.put(ICON, R.drawable.right);
    data.add(map);

Then on click, display the menu using this function:

private void showListMenu(final View anchor) {
    popupWindow = new ListPopupWindow(this);

    ListAdapter adapter = new SimpleAdapter(
            this,
            data,
            R.layout.shoe_select,
            new String[] {TITLE, ICON}, // These are just the keys that the data uses (constant strings)
            new int[] {R.id.shoe_select_text, R.id.shoe_select_icon}); // The view ids to map the data to

    popupWindow.setAnchorView(anchor);
    popupWindow.setAdapter(adapter);
    popupWindow.setWidth(400);
    popupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            switch (position){
                case 0:
                    devicesAdapter.setSelectedLeftPosition(devicesList.getChildAdapterPosition(anchor));
                    break;
                case 1:
                    devicesAdapter.setSelectedRightPosition(devicesList.getChildAdapterPosition(anchor));
                    break;
                default:
                    break;
            }
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    devicesAdapter.notifyDataSetChanged();
                }
            });
            popupWindow.dismiss();
        }
    });
    popupWindow.show();
}

import data  from './data.json';
export class AppComponent  {
    json:any = data;
}

Every interface is implicitly abstract.
This modifier is obsolete and should not be used in new programs.

[The Java Language Specification - 9.1.1.1 abstract Interfaces]

Also note that interface member methods are implicitly public abstract.
[The Java Language Specification - 9.2 Interface Members]

Why are those modifiers implicit? There is no other modifier (not even the 'no modifier'-modifier) that would be useful here, so you don't explicitly have to type it.

dispatch_async(dispatch_get_global_queue(QOS_CLASS_BACKGROUND, 0), {
    // Conversion into base64 string
    self.uploadImageString =  uploadPhotoDataJPEG.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.EncodingEndLineWithCarriageReturn)
})

function setMarkers(map,locations){

for (var i = 0; i < locations.length; i++)
 {  

 var loan = locations[i][0];
 var lat = locations[i][1];
 var long = locations[i][2];
 var add =  locations[i][3];

 latlngset = new google.maps.LatLng(lat, long);

 var marker = new google.maps.Marker({  
          map: map, title: loan , position: latlngset  
 });
 map.setCenter(marker.getPosition());


 marker.content = "<h3>Loan Number: " + loan +  '</h3>' + "Address: " + add;


 google.maps.events.addListener(marker,'click', function(map,marker){
          map.infowindow.setContent(marker.content);
          map.infowindow.open(map,marker);

 });

 }
}

Then move var infowindow = new google.maps.InfoWindow() to the initialize() function:

function initialize() {

    var myOptions = {
      center: new google.maps.LatLng(33.890542, 151.274856),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("default"),
        myOptions);
    map.infowindow = new google.maps.InfoWindow();

    setMarkers(map,locations)

  }

         bool breakInnerLoop=false
        for(int i=0;i<=10;i++)
        {
          for(int J=0;i<=10;i++)
          {
              if(i<=j)
                {
                    breakInnerLoop=true;
                    break;
                }
          }
            if(breakInnerLoop)
            {
            continue
            }
        }

You can use option:selected to get the chosen option of the select element, then the text() method:

$("select option:selected").text();

Here's an example:

console.log($("select option:selected").text());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
<select>_x000D_
    <option value="1">Volvo</option>_x000D_
    <option value="2" selected="selected">Saab</option>_x000D_
    <option value="3">Mercedes</option>_x000D_
</select>

Use regular expression:

String s="your1string2contain3with4number";
int i=Integer.parseInt(s.replaceAll("[\\D]", ""))

output: i=1234;

If you need first number combination then you should try below code:

String s="abc123xyz456";
int i=((Number)NumberFormat.getInstance().parse(s)).intValue()

output: i=123;

There are a few possibilities:

1. Your workstation doesn't have the root CA cert used to sign your server's cert. How exactly you fix that depends on what OS you're running and what release, etc. (I suspect this is not related)
2. Your cert isn't installed properly. If your SSL cert requires an intermediate cert to be presented and you didn't set that up, you can get these warnings.
3. Are you sure you've enabled SSL on port 443?

For starters, to eliminate (3), what happens if you telnet to that port?

Assuming it's not (3), then depending on your needs you may be fine with ignoring these errors and just passing --no-certificate-check. You probably want to use a regular browser (which generally will bundle the root certs directly) and see if things are happy.

If you want to manually verify the cert, post more details from the openssl s_client output. Or use openssl x509 -text -in /path/to/cert to print it out to your terminal.

Your HttpServletRequest object has a getParameter(String paramName) method that can be used to get parameter values. http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.html#getParameter(java.lang.String)

Use the display property

a{
    display: block;
}

This will make the link to display in new line

If you want to remove list styling, use

li{
    list-style: none;
}

Eclipse itself will add the @Override annotation when you tell it to "generate unimplemented methods" during creation of a class that implements an interface.

init() return none value solved perfectly

class Solve:
def __init__(self,w,d):
    self.value=w
    self.unit=d
def __str__(self):
    return str("my speed is "+str(self.value)+" "+str(self.unit))
ob=Solve(21,'kmh')
print (ob)

output: my speed is 21 kmh

You can define multiple routes with and without parameter:

@RouteConfig([
    { path: '/user/:id', component: User, name: 'User' },
    { path: '/user', component: User, name: 'Usernew' }
])

and handle the optional parameter in your component:

constructor(params: RouteParams) {
    var paramId = params.get("id");

    if (paramId) {
        ...
    }
}

If you are using a client like MySQL Workbench, right click the desired table from where a foreign key is to be deleted, then select the foreign key tab and delete the indexes.

Then you can run the query like this:

alter table table_name drop foreign_key_col_name;

package lecture3;

import java.util.Scanner;

public class divisibleBy2and5 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("Enter an integer number:");
        Scanner input = new Scanner(System.in);
        int x;
        x = input.nextInt();
         if (x % 2==0){
             System.out.println("The integer number you entered is divisible by 2");
         }
         else{
             System.out.println("The integer number you entered is not divisible by 2");
             if(x % 5==0){
                 System.out.println("The integer number you entered is divisible by 5");
             } 
             else{
                 System.out.println("The interger number you entered is not divisible by 5");
             }
        }

    }
}

For those using Python-3

Using traceback module and exception.__traceback__ one can extract the stack-trace as follows:

• grab the current stack-trace using traceback.extract_stack()
• remove the last three elements (as those are entries in the stack that got me to my debug function)
• append the __traceback__ from the exception object using traceback.extract_tb()
• format the whole thing using traceback.format_list()

import traceback
def exception_to_string(excp):
   stack = traceback.extract_stack()[:-3] + traceback.extract_tb(excp.__traceback__)  # add limit=?? 
   pretty = traceback.format_list(stack)
   return ''.join(pretty) + '\n  {} {}'.format(excp.__class__,excp)

A simple demonstration:

def foo():
    try:
        something_invalid()
    except Exception as e:
        print(exception_to_string(e))

def bar():
    return foo()

We get the following output when we call bar():

  File "./test.py", line 57, in <module>
    bar()
  File "./test.py", line 55, in bar
    return foo()
  File "./test.py", line 50, in foo
    something_invalid()

  <class 'NameError'> name 'something_invalid' is not defined

Python does not have these operators, but if you really need them you can write a function having the same functionality.

def PreIncrement(name, local={}):
    #Equivalent to ++name
    if name in local:
        local[name]+=1
        return local[name]
    globals()[name]+=1
    return globals()[name]

def PostIncrement(name, local={}):
    #Equivalent to name++
    if name in local:
        local[name]+=1
        return local[name]-1
    globals()[name]+=1
    return globals()[name]-1

Usage:

x = 1
y = PreIncrement('x') #y and x are both 2
a = 1
b = PostIncrement('a') #b is 1 and a is 2

Inside a function you have to add locals() as a second argument if you want to change local variable, otherwise it will try to change global.

x = 1
def test():
    x = 10
    y = PreIncrement('x') #y will be 2, local x will be still 10 and global x will be changed to 2
    z = PreIncrement('x', locals()) #z will be 11, local x will be 11 and global x will be unaltered
test()

Also with these functions you can do:

x = 1
print(PreIncrement('x'))   #print(x+=1) is illegal!

But in my opinion following approach is much clearer:

x = 1
x+=1
print(x)

Decrement operators:

def PreDecrement(name, local={}):
    #Equivalent to --name
    if name in local:
        local[name]-=1
        return local[name]
    globals()[name]-=1
    return globals()[name]

def PostDecrement(name, local={}):
    #Equivalent to name--
    if name in local:
        local[name]-=1
        return local[name]+1
    globals()[name]-=1
    return globals()[name]+1

I used these functions in my module translating javascript to python.

Mike Nereson has this to say on his blog at:

http://blog.codehangover.com/load-multiple-contexts-into-spring/

There are a couple of ways to do this.

1. web.xml contextConfigLocation

Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value>
          applicationContext1.xml
          applicationContext2.xml
      </param-value>
  </context-param>

  <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>

The above uses carriage returns. Alternatively, yo could just put in a space.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value> applicationContext1.xml applicationContext2.xml </param-value>
  </context-param>

  <listener>
      <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
  </listener>

2. applicationContext.xml import resource

Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.

In applicationContext.xml you might have…

  <!-- hibernate configuration and mappings -->
  <import resource="applicationContext-hibernate.xml"/>

  <!-- ldap -->
  <import resource="applicationContext-ldap.xml"/>

  <!-- aspects -->
  <import resource="applicationContext-aspects.xml"/>

Which strategy should you use?

1. I always prefer to load up via web.xml.

Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay loosely coupled, so that in the future I can extract a package or vertical layer and move it to its own module.

2. If you are loading contexts into a non-web application, I would use the import resource.

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

It's the same origin policy, you have to use a JSON-P interface or a proxy running on the same host.

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

According to PEP8, long lines should be placed in parentheses. When using parentheses, the lines can be broken up without using backslashes. You should also try to put the line break after boolean operators.

Further to this, if you're using a code style check such as pycodestyle, the next logical line needs to have different indentation to your code block.

For example:

if (abcdefghijklmnopqrstuvwxyz > some_other_long_identifier and
        here_is_another_long_identifier != and_finally_another_long_name):
    # ... your code here ...
    pass

Open up Xcode, and accept the new user agreement. This was happening because a new version of Xcode was downloaded and the new agreement was not accepted.

Generally, when you create an index on a table, database will automatically use that index while searching for data in that table. You don't need to do anything about that.

However, in MSSQL, you can specify an index hint which can specify that a particular index should be used to execute this query. More information about this can be found here.

Index hint is also seems to be available for MySQL. Thanks to Tudor Constantine.

• First convert string to java.util.Date using date formatter
• Use getTime() to obtain count of millisecs from date

I do not believe there is a way to do this strictly with CSS. The reason is your "important" qualifier to the question: forcing the parent element to expand with the contents of its child.

My guess is that you will have to use some bits of JavaScript to find the height of the child, and make adjustments.

So, with this HTML:

<div class="parentElement">  
  <div class="childElement">  
    ...Some Contents...  
  </div>  
</div>  

This CSS:

.parentElement {  
  position:relative;
  width:960px;
}
.childElement {
  position:absolute;
  top:50%;
  left:50%;
}

This jQuery might be useful:

$('.childElement').each(function(){
  // determine the real dimensions of the element: http://api.jquery.com/outerWidth/
  var x = $(this).outerWidth();
  var y = $(this).outerHeight();
  // adjust parent dimensions to fit child
  if($(this).parent().height() < y) {
    $(this).parent().css({height: y + 'px'});
  }
  // offset the child element using negative margins to "center" in both axes
  $(this).css({marginTop: 0-(y/2)+'px', marginLeft: 0-(x/2)+'px'});
});

Remember to load the jQ properly, either in the body below the affected elements, or in the head inside of $(document).ready(...).

 $('.checkbox').attr('checked',true);

will not work with from jQuery 1.6.

Instead use

$('.checkbox').prop('checked',true);
$('.checkbox').prop('checked',false);

This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

<LimitExcept OPTIONS>
    AuthType Basic
    AuthName <AUTH_NAME>
    Require valid-user
    AuthUserFile <FILE_PATH>
</LimitExcept>

This is really just an expansion of BBB's answer which lead to to get my experiment working.

This script will simply create a file /tmp/testfile when you click on the button that says "Open Script".

This requires 3 files.

1. The actual HTML Website with a button.
2. A php script which executes the script
3. A Script

The File Tree:

root@test:/var/www/html# tree testscript/
testscript/
+-- index.html
+-- testexec.php
+-- test.sh

1. The main WebPage:

root@test:/var/www/html# cat testscript/index.html
<form action="/testscript/testexec.php">
    <input type="submit" value="Open Script">
</form>

2. The PHP Page that runs the script and redirects back to the main page:

root@test:/var/www/html# cat testscript/testexec.php
<?php
shell_exec("/var/www/html/testscript/test.sh");
header('Location: http://192.168.1.222/testscript/index.html?success=true');
?>

3. The Script :

root@test:/var/www/html# cat testscript/test.sh

#!/bin/bash

touch /tmp/testfile

This is the better way that I use to create submit without loading in a form.

You can use some CSS to stylise the iframe the way you want.

A php result will be loaded into the iframe.

<form method="post" action="test.php" target="view">
  <input type="text" name="anyname" palceholder="Enter your name"/>
  <input type="submit" name="submit" value="submit"/>
  </form>
<iframe name="view" frameborder="0" style="width:100%">
  </iframe>

The CSS below stops users from being able to select text.

-webkit-user-select: none; /* Safari */        
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* IE10+/Edge */
user-select: none; /* Standard */

To target IE9 downwards the html attribute unselectable must be used instead:

<p unselectable="on">Test Text</p>

I also had this problem: ie., csv files (comma delimited, double quote delimited strings) with LF in quoted strings. These were downloaded Square files. I did a data import but instead of importing as text files, imported as "from HTML". This time it ignored the LF's in the quoted strings.

Java is a kind of object-oriented programming, not a procedure programming. So every thing in your code should be manipulating an object.

public static void main is only the entry of your program. It does not involve any object behind.

So what is coding with an object? It is simple, you need to create a particular object/instance, call their methods to change their states, or do other specific function within that object.

e.g. just like

private ReportHandler rh = new ReportHandler();
rh.<function declare in your Report Handler class>

So when you declare a static method, it doesn't associate with your object/instance of your object. And it is also violate with your O-O programming.

static method is usually be called when that function is not related to any object behind.

Simply check if there is a protocol (delineated by "://") and add "http://" if there isn't.

if (false === strpos($url, '://')) {
    $url = 'http://' . $url;
}

Note: This may be a simple and straightforward solution, but Jack's answer using parse_url is almost as simple and much more robust. You should probably use that one.

Basically destroy runs any callbacks on the model while delete doesn't.

From the Rails API:

• ActiveRecord::Persistence.delete

  Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can't be persisted). Returns the frozen instance.

  The row is simply removed with an SQL DELETE statement on the record's primary key, and no callbacks are executed.

  To enforce the object's before_destroy and after_destroy callbacks or any :dependent association options, use #destroy.

• ActiveRecord::Persistence.destroy

  Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can't be persisted).

  There's a series of callbacks associated with destroy. If the before_destroy callback return false the action is cancelled and destroy returns false. See ActiveRecord::Callbacks for further details.

I used the below connection string on the Advanced tab of MySQL Migration Tool Kit to connect to SQL Server 2008 instance:

jdbc:jtds:sqlserver://"sql_server_ip_address":1433/<db_name>;Instance=<sqlserver_instanceName>;user=sa;password=PASSWORD;namedPipe=true;charset=utf-8;domain= 

Usually the parameter has "systemName\instanceName". But in the above, do not add "systemName\" (use only InstanceName).

To check what the instanceName should be, go to services.msc and check the DisplayName of the MSSQL instance. It shows similar to MSSQL$instanceName.

Hope this help in MSSQL connectivity from mysql migration toolKit.

All you need to know about relative file paths:

Starting with "/" returns to the root directory and starts there

Starting with "../" moves one directory backward and starts there

Starting with "../../" moves two directories backward and starts there (and so on...)

To move forward, just start with the first subdirectory and keep moving forward

Is there any command in Linux through which i can know if the process is in hang state.

There is no command, but once I had to do a very dumb hack to accomplish something similar. I wrote a Perl script which periodically (every 30 seconds in my case):

• run ps to find list of PIDs of the watched processes (along with exec time, etc)
• loop over the PIDs
• start gdb attaching to the process using its PID, dumping stack trace from it using thread apply all where, detaching from the process
• a process was declared hung if:
  • its stack trace didn't change and time didn't change after 3 checks
  • its stack trace didn't change and time was indicating 100% CPU load after 3 checks
• hung process was killed to give a chance for a monitoring application to restart the hung instance.

But that was very very very very crude hack, done to reach an about-to-be-missed deadline and it was removed a few days later, after a fix for the buggy application was finally installed.

Otherwise, as all other responders absolutely correctly commented, there is no way to find whether the process hung or not: simply because the hang might occur for way to many reasons, often bound to the application logic.

The only way is for application itself being capable of indicating whether it is alive or not. Simplest way might be for example a periodic log message "I'm alive".

In SQL Developer you can right-click on the package body then select RUN. The 'Run PL/SQL' window will let you edit the PL/SQL Block. Clicking OK will give you a window pane titled 'Output Variables - Log' with an output variables tab. You can select your output variables on the left and the result is shown on the right side. Very handy and fast.

I've used Rapid with T-SQL and I think there was something similiar to this.

Writing your own delcare-begin-end script where you loop through the cursor, as with DCookie's example, is always a good exercise to do every now and then. It will work with anything and you will know that your code works.

With me it helped changing the compiler compliance level. For unknown reasons it was set to 1.6 and I changed it to 1.8.

Once at project level right click on project > Properties > Java Compiler, while in Eclipse click on menu Window > Preferences > Java > Compiler.

SET @table = 'the_table';
SELECT GROUP_CONCAT(IF(COLUMN_NAME IN ('id'), 0, CONCAT("\`", COLUMN_NAME, "\`"))) FROM INFORMATION_SCHEMA.COLUMNS
                  WHERE TABLE_SCHEMA = DATABASE() AND TABLE_NAME = @table INTO @columns;
SET @s = CONCAT('INSERT INTO ', @table, ' SELECT ', @columns,' FROM ', @table, ' WHERE id=1');
PREPARE stmt FROM @s;
EXECUTE stmt;

If both are not going to be modified (no adding/deleting items - modifying existing ones is fine as long as you pay heed to threading issues), you can simply pass around data.begin() + 100000 and data.begin() + 101000, and pretend that they are the begin() and end() of a smaller vector.

Or, since vector storage is guaranteed to be contiguous, you can simply pass around a 1000 item array:

T *arrayOfT = &data[0] + 100000;
size_t arrayOfTLength = 1000;

Both these techniques take constant time, but require that the length of data doesn't increase, triggering a reallocation.

I tried Alexanders answer but got this error in Python3:

TypeError: 'float' object cannot be interpreted as an integer

This is because the division operator in Python3 is returning a float. This works for me:

>>> x = "qwertyui"
>>> chunks, chunk_size = len(x), len(x)//4
>>> [ x[i:i+chunk_size] for i in range(0, chunks, chunk_size) ]
['qw', 'er', 'ty', 'ui']

Notice the // at the end of line 2, to ensure truncation to an integer.

A few comments on the accepted answer:

The + means "1 or more". I don't think you need to repeat \s. I think you can simply write '/\s+/'.

Also, if you want to remove whitespace first and last in the string, add trim.

With these modifications, the code would be:

$string = preg_replace('/\s+/', ' ', trim($string));

You can achieve this by adding this simple php code block

<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
      the_content();
      endwhile; else: ?>
      <p>!Sorry no posts here</p>
<?php endif; ?>

Basically run it with:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1044

The application, at launch, will wait until you connect from another source.

grep '^[0-9]\{1,16\}' | wc -l

Gives the counts with exact match count with limit

I had a similar issue when performing a file download through Javascript. Adding the download attribute made no difference but adding target='_blank' did - I no longer get the 'Resource interpreted as Document...' console message.

Here's my nicely simple code:

var link = document.createElement('a');
link.target = '_blank';
link.href = url;
document.body.appendChild(link); // Required for Firefox
link.click();
link.remove(); 

I haven't tried it with direct HTML but would expect it to work.

Note I discovered that Firefox requires the link to be appended to the document whereas Chrome will work without it.

The following line:

string getusername = command.ExecuteScalar();

... will try to implicitly convert the result to string, like below:

string getusername = (string)command.ExecuteScalar();

The regular casting operator will fail if the object is null. Try using the as-operator, like this:

string getusername = command.ExecuteScalar() as string;

Ivo's answer is good, but I prefer to not match on \w because there's no need to capitalize 0-9 and A-Z. We can ignore those and only match on a-z.

'your string'.replace(/\b[a-z]/g, match => match.toUpperCase())
// => 'Your String'

It's the same output, but I think clearer in terms of self-documenting code.

That means you must install simplejson. On newer versions of python, it was included by default into python's distribution, and renamed to json. So if you are on python 2.6+ you should change all instances of simplejson to json.

For a quick fix you could also edit the file and change the line:

import simplejson

to:

import json as simplejson

and hopefully things will work.

More recent versions have a different syntax:

var table = $('#example').DataTable();

// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
    table.search(this.value).draw();
});

Note that this example uses the variable table assigned when datatables is first initialised. If you don't have this variable available, simply use:

var table = $('#example').dataTable().api();

// #myInput is a <input type="text"> element
$('#myInput').on('keyup change', function () {
    table.search(this.value).draw();
});

Since: DataTables 1.10

A one liner would be :

str=str[::-1].replace(".",".-",1)[::-1]

It sounds like you answered your own question. get_class will get you the class name. It is procedural and maybe that is what is causing the confusion. Take a look at the php documentation for get_class

Here is their example:

 <?php

 class foo 
 {
     function name()
     {
         echo "My name is " , get_class($this) , "\n";
     }
 }

 // create an object
 $bar = new foo();

 // external call
 echo "Its name is " , get_class($bar) , "\n"; // It's name is foo

 // internal call
 $bar->name(); // My name is foo

To make it more like your example you could do something like:

 <?php

 class MyClass
 {
       public static function getClass()
       {
            return get_class();
       }
 }

Now you can do:

 $className = MyClass::getClass();

This is somewhat limited, however, because if my class is extended it will still return 'MyClass'. We can use get_called_class instead, which relies on Late Static Binding, a relatively new feature, and requires PHP >= 5.3.

<?php

class MyClass
{
    public static function getClass()
    {
        return get_called_class();
    }

    public static function getDefiningClass()
    {
        return get_class();
    }
}

class MyExtendedClass extends MyClass {}

$className = MyClass::getClass(); // 'MyClass'
$className = MyExtendedClass::getClass(); // 'MyExtendedClass'
$className = MyExtendedClass::getDefiningClass(); // 'MyClass'

One thing that should be considered is licensing.

Notepad++ is free (as in speech and as in beer) for perpetual use, released under the GPL license, whereas Sublime Text 2 requires a license.

To quote the Sublime Text 2 website:

..a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

The same is now true of Sublime Text 3, and a paid upgrade will be needed for future versions.

Upgrade Policy A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade.

This licensing requirement is still correct as of Dec 2019.

All you need is to make an ajax request to your pythoncode. You can do this with jquery http://api.jquery.com/jQuery.ajax/, or use just javascript

$.ajax({
  type: "POST",
  url: "~/pythoncode.py",
  data: { param: text}
}).done(function( o ) {
   // do something
});

I think this is actually what you're looking for:

.my_container ul
{
    list-style: initial;
    margin: initial;
    padding: 0 0 0 40px;
}

.my_container li
{
    display: list-item;
}

You can use this, it is pretty cool:

import dataconverters.commas as commas
filename = 'test.csv'
with open(filename) as f:
      records, metadata = commas.parse(f)
      for row in records:
            print 'this is row in dictionary:'+rowenter code here

It's easy enough to "roll your own" version of a dictionary that allows "duplicate key" entries. Here is a rough simple implementation. You might want to consider adding support for basically most (if not all) on IDictionary<T>.

public class MultiMap<TKey,TValue>
{
    private readonly Dictionary<TKey,IList<TValue>> storage;

    public MultiMap()
    {
        storage = new Dictionary<TKey,IList<TValue>>();
    }

    public void Add(TKey key, TValue value)
    {
        if (!storage.ContainsKey(key)) storage.Add(key, new List<TValue>());
        storage[key].Add(value);
    }

    public IEnumerable<TKey> Keys
    {
        get { return storage.Keys; }
    }

    public bool ContainsKey(TKey key)
    {
        return storage.ContainsKey(key);
    }

    public IList<TValue> this[TKey key]
    {
        get
        {
            if (!storage.ContainsKey(key))
                throw new KeyNotFoundException(
                    string.Format(
                        "The given key {0} was not found in the collection.", key));
            return storage[key];
        }
    }
}

A quick example on how to use it:

const string key = "supported_encodings";
var map = new MultiMap<string,Encoding>();
map.Add(key, Encoding.ASCII);
map.Add(key, Encoding.UTF8);
map.Add(key, Encoding.Unicode);

foreach (var existingKey in map.Keys)
{
    var values = map[existingKey];
    Console.WriteLine(string.Join(",", values));
}

After changing the context root in project properties you have to remove your web application from Tomcat (using Add and Remove... on the context menu of the server), redeploy, then re-add your application and redeploy. It worked for me.

If you are struck you have another choice: select the Tomcat server in the Servers view. Double clicking on that server (or selecting Open in the context menu) brings a multipage editor where there is a Modules page. Here you can change the root context of your module (called Path on this page).

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

This error message appears if the Windows service launcher has quit immediately after being started. This problem usually happens because the license key has not been correctly deployed(license.txt file in the license folder). If service is not strtign with correct key, just put incorrect key and try to start. Once started, place the correct key, it will work.

%~dp0 expands to current directory path of the running batch file.

To get clear understanding, let's create a batch file in a directory.

C:\script\test.bat

with contents:

@echo off
echo %~dp0

When you run it from command prompt, you will see this result:

C:\script\

As the other answers state, you need to select an active scheme to something that is not a simulator, i.e. a device that's connected to your mac.

If you have no device connected to the mac then selecting "Generic IOS Device" works also.

                encodeURIComponent(json[key]);
        }).join('&');

npm i moment-timezone

If you are working with devtools try to save the files with:

devtools::use_data(x, internal = TRUE)

Then, delete all files saved previously.

From doc:

internal If FALSE, saves each object in individual .rda files in the data directory. These are available whenever the package is loaded. If TRUE, stores all objects in a single R/sysdata.rda file. These objects are only available within the package.

create your own style overriding android:Theme

Then use it in manifest like this:

    android:theme="@style/noAnimationStyle">

In Kotlin you must use MutableList or ArrayList.

Let's see how the methods of MutableList work:

var listNumbers: MutableList<Int> = mutableListOf(10, 15, 20)
// Result: 10, 15, 20

listNumbers.add(1000)
// Result: 10, 15, 20, 1000

listNumbers.add(1, 250)
// Result: 10, 250, 15, 20, 1000

listNumbers.removeAt(0)
// Result: 250, 15, 20, 1000

listNumbers.remove(20)
// Result: 250, 15, 1000

for (i in listNumbers) { 
    println(i) 
}

Let's see how the methods of ArrayList work:

var arrayNumbers: ArrayList<Int> = arrayListOf(1, 2, 3, 4, 5)
// Result: 1, 2, 3, 4, 5

arrayNumbers.add(20)
// Result: 1, 2, 3, 4, 5, 20

arrayNumbers.remove(1)
// Result: 2, 3, 4, 5, 20

arrayNumbers.clear()
// Result: Empty

for (j in arrayNumbers) { 
    println(j) 
}

I've found this one useful. Because if the recursion it can print nested tables too. It doesn't give the prettiest formatting in the output but for such a simple function it's hard to beat for debugging.

function dump(o)
   if type(o) == 'table' then
      local s = '{ '
      for k,v in pairs(o) do
         if type(k) ~= 'number' then k = '"'..k..'"' end
         s = s .. '['..k..'] = ' .. dump(v) .. ','
      end
      return s .. '} '
   else
      return tostring(o)
   end
end

e.g.

local people = {
   {
      name = "Fred",
      address = "16 Long Street",
      phone = "123456"
   },

   {
      name = "Wilma",
      address = "16 Long Street",
      phone = "123456"
   },

   {
      name = "Barney",
      address = "17 Long Street",
      phone = "123457"
   }

}

print("People:", dump(people))

Produces the following output:

People: { [1] = { ["address"] = 16 Long Street,["phone"] = 123456,["name"] = Fred,} ,[2] = { ["address"] = 16 Long Street,["phone"] = 123456,["name"] = Wilma,} ,[3] = { ["address"] = 17 Long Street,["phone"] = 123457,["name"] = Barney,} ,}

You can convert the dates into UNIX timestamps and compare the difference between them in seconds.

$today_date=date("Y-m-d");
$entered_date=$_POST['date'];
$dateTimestamp1 = strtotime($today_date);
$dateTimestamp2 = strtotime($entered_date);
$diff= $dateTimestamp1-$dateTimestamp2;
//echo $diff;
if ($diff<=0)
   {
     echo "Enter a valid date";
   }

My first impulse was to google for "php math" and I discovered that there's a core math library function called "round()" that likely is what you want.

If you are trying to determine the width of a mix of text nodes and elements inside a given element, you need to wrap all the contents with wrapInner(), calculate the width, and then unwrap the contents.

*Note: You will also need to extend jQuery to add an unwrapInner() function since it is not provided by default.

$.fn.extend({
  unwrapInner: function(selector) {
      return this.each(function() {
          var t = this,
              c = $(t).children(selector);
          if (c.length === 1) {
              c.contents().appendTo(t);
              c.remove();
          }
      });
  },
  textWidth: function() {
    var self = $(this);
    $(this).wrapInner('<span id="text-width-calc"></span>');
    var width = $(this).find('#text-width-calc').width();
    $(this).unwrapInner();
    return width;
  }
});

You can try this instead


var myu = document.getElementById('myu').value;
var myp = document.getElementById('myp').value;
window.opener.location.href='myurl.php?myu='+ myu +'&myp='+ myp;

Note: Do not use this method to pass sensitive information like username, password.

resoverall is a sqlalchemy ResultProxy object. You can read more about it in the sqlalchemy docs, the latter explains basic usage of working with Engines and Connections. Important here is that resoverall is dict like.

Pandas likes dict like objects to create its data structures, see the online docs

Good luck with sqlalchemy and pandas.

I got this error when one of my properties that was required for the constructor was not public. Make sure all the parameters in the constructor go to properties that are public if this is the case:

using statements namespace someNamespace

public class ExampleClass {

  //Properties - one is not visible to the class calling the constructor
  public string Property1 { get; set; }
  string Property2 { get; set; }

   //Constructor
   public ExampleClass(string property1, string property2)
  {
     this.Property1 = property1;
     this.Property2 = property2;  //this caused that error for me
  }
}

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

Here's a Ruby gem that implements the Largest Remainder method: https://github.com/jethroo/lare_round

To use:

a =  Array.new(3){ BigDecimal('0.3334') }
# => [#<BigDecimal:887b6c8,'0.3334E0',9(18)>, #<BigDecimal:887b600,'0.3334E0',9(18)>, #<BigDecimal:887b4c0,'0.3334E0',9(18)>]
a = LareRound.round(a,2)
# => [#<BigDecimal:8867330,'0.34E0',9(36)>, #<BigDecimal:8867290,'0.33E0',9(36)>, #<BigDecimal:88671f0,'0.33E0',9(36)>]
a.reduce(:+).to_f
# => 1.0

Finding all possible paths is a hard problem, since there are exponential number of simple paths. Even finding the kth shortest path [or longest path] are NP-Hard.

One possible solution to find all paths [or all paths up to a certain length] from s to t is BFS, without keeping a visited set, or for the weighted version - you might want to use uniform cost search

Note that also in every graph which has cycles [it is not a DAG] there might be infinite number of paths between s to t.

from bower help, save option has a capital S

!- Adding this for reference, don't know how outdated the information might be, but it tells about a few simple solutions that don't require the use of any scripting

After searching for this myself i came across this page but also these pages:

http://nadeausoftware.com/articles/2007/05/stop_spammer_email_harvesters_obfuscating_email_addresses

try reversing the emailadress

Example plain HTML:

<bdo dir="rtl">moc.elpmaxe@nosrep</bdo>
Result : [email protected]

The same effect using CSS

CSS:
.reverse { unicode-bidi:bidi-override; direction:rtl; }
HTML:
<span class="reverse">moc.elpmaxe@nosrep</span>
Result : [email protected]

Combining this with any of earlier mentioned methods may even make it more effective

At the bottom of the Sublime window, you'll see something representing your tab/space setting.

You'll then get a dropdown with a bunch of options. The options you care about are:

• Convert Indentation to Spaces
• Convert Indentation to Tabs

Apply your desired setting to the entire document.

Hope this helps.

Try this

$.trim($("#spa").val()).length > 0

It will not treat any white space if any as a correct value

Faced with the same problem, I was able to solve it using only vanilla JS, but in an ugly way. To be more accurate, in a non-procedural way. I removed all my function parameters and return values and replaced them with global variables, and now the functions only serve as containers for lines of code - they're no longer logical units.

In my case, I also had the added complication of needing many confirmations (as a parser works through a text). My solution was to put everything up to the first confirmation in a JS function that ends by painting my custom popup on the screen, and then terminating.

Then the buttons in my popup call another function that uses the answer and then continues working (parsing) as usual up to the next confirmation, when it again paints the screen and then terminates. This second function is called as often as needed.

Both functions also recognize when the work is done - they do a little cleanup and then finish for good. The result is that I have complete control of the popups; the price I paid is in elegance.

In VS 2010:

Tools > Settings > Expert Settings

Then:

Tools > Options > Show all settings > Text editor > C# > General > Check Line Numbers (checkbox)

Or you can do it that manner:

for key in my_dict:
     print key, my_dict[key]

Short answer No. CSS is not specific to brands.

Below are the articles to implement for iOS using media only.

https://css-tricks.com/snippets/css/media-queries-for-standard-devices/

http://stephen.io/mediaqueries/

Infact you can use PHP, Javascript to detect the iOS browser and according to that you can call CSS file. For instance

http://www.kevinleary.net/php-detect-ios-mobile-users/

Running commands periodically without cron is possible when we go with while.

As a command:

while true ; do command ; sleep 100 ; done &
[ ex: # while true;  do echo `date` ; sleep 2 ; done & ]

Example:

while true
do echo "Hello World"
sleep 100
done &

Do not forget the last & as it will put your loop in the background. But you need to find the process id with command "ps -ef | grep your_script" then you need to kill it. So kindly add the '&' when you running the script.

# ./while_check.sh &

Here is the same loop as a script. Create file "while_check.sh" and put this in it:

#!/bin/bash
while true; do 
    echo "Hello World" # Substitute this line for whatever command you want.
    sleep 100
done

Then run it by typing bash ./while_check.sh &

You should note that putting generated metadata under version control (let it be git or any other scm), is not a very good idea if there are more than one developer working on the codebase. Two developers may have a totally different project or classpath setup. Just as a heads up in case you intends to share the code at some time...

Here's how I solved it. This works if you also use this for editing.

@Html.TextBoxFor(m => m.Age, new { Value = Model.Age.ToString() ?? "0" })

You can use Local storage.

local storage is same as session. the data will be removed when you close the browser.

<script> 
localStorage.setItem('lastname','Smith');

alert(localStorage.getItem('lastname'));
</script>

Edit: @Naveen comment below is correct. You can use session storage instead. (https://www.w3schools.com/jsref/prop_win_sessionstorage.asp) Thanks.

<script> 
sessionStorage.setItem('lastname','Smith');

alert(sessionStorage.getItem('lastname'));
</script>

Dynamic function names and namespaces

Just to add a point about dynamic function names when using namespaces.

If you're using namespaces, the following won't work except if your function is in the global namespace:

namespace greetings;

function hello()
{
    // do something
}

$myvar = "hello";
$myvar(); // interpreted as "\hello();"

What to do?

You have to use call_user_func() instead:

// if hello() is in the current namespace
call_user_func(__NAMESPACE__.'\\'.$myvar);

// if hello() is in another namespace
call_user_func('mynamespace\\'.$myvar);

You can reset the plot by doing this:

dev.off()

use:

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

Signed left shift Logically Simple if 1<<11 it will tends to 2048 and 2<<11 will give 4096

In java programming int a = 2 << 11;

// it will result in 4096

2<<11 = 2*(2^11) = 4096

You could also use Django Crispy Forms, it's a great tool to define forms in case you'd like to use some CSS framework like Bootstrap or Foundation. And it's easy to specify classes for your form fields there.

Your form class would like this then:

from django import forms

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Div, Submit, Field
from crispy_forms.bootstrap import FormActions

class SampleClass(forms.Form):
    name = forms.CharField(max_length=30)
    age = forms.IntegerField()
    django_hacker = forms.BooleanField(required=False)

    helper = FormHelper()
    helper.form_class = 'your-form-class'
    helper.layout = Layout(
        Field('name', css_class='name-class'),
        Field('age', css_class='age-class'),
        Field('django_hacker', css-class='hacker-class'),
        FormActions(
            Submit('save_changes', 'Save changes'),
        )
    )

As per the current setup on June, 2017 Here is the downloadable link for Visual C++ 2015 Redistributable package : https://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x64.exe

Hope this will help, who are struggling with the download link.

Note: This is with regards to MySQL Workbench 6.3.9

I had a similar issue where I was creating a numeric color without considering the leading alpha channel. ie. mytext.setTextColor(0xFF0000) (thinking this would be red ). While this is a red color it is also 100% transparent as it = 0x00FF0000; The correct 100% opaque value is 0xFFFF0000 or mytext.setTextcolor(0xFFFF0000).

I like this if you want to get just some parts of the query:

new CriteriaQueryTranslator(
    factory,
    executableCriteria,
    executableCriteria.getEntityOrClassName(), 
    CriteriaQueryTranslator.ROOT_SQL_ALIAS)
        .getWhereCondition();

For instance something like this:

String where = new CriteriaQueryTranslator(
    factory,
    executableCriteria,
    executableCriteria.getEntityOrClassName(), 
    CriteriaQueryTranslator.ROOT_SQL_ALIAS)
        .getWhereCondition();

String sql = "update my_table this_ set this_.status = 0 where " + where;

Most probably the issue happens because of the incompatability of 32 bit and 64 bit excecutables. Suppose if you have installed 32 bit Android Studio by mistake and you will be downloading a 64 bit JDK. In this case 32 bit Android Studio will not be able to pick up the 64 bit JDK. This was the issue I faced. So I followed the below simple steps to make it working,

1. Downloaded 32 bit JDK(you can also download 64 bit Android Studio if you do not want to change the 64 bit JDK)
2. Right click MyComputer > Advanced System Settings > under 'Advanced tab' > Environment variables > Under System Variables > Add JAVA_HOME as key and your jdk(eg:C:\Program Files (x86)\Java\jdk1.7.0_79) location as value.
3. Save it and launch Android Studio. You are good to go now.

Right, click on the project. Go to Maven -> Update Project.

The dependencies will automatically be installed.

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

Consider following code

<ul id="myTask">
  <li>Coding</li>
  <li>Answering</li>
  <li>Getting Paid</li>
</ul>

Now, here goes the difference

// Remove the myTask item when clicked.
$('#myTask').children().click(function () {
  $(this).remove()
});

Now, what if we add a myTask again?

$('#myTask').append('<li>Answer this question on SO</li>');

Clicking this myTask item will not remove it from the list, since it doesn't have any event handlers bound. If instead we'd used .on, the new item would work without any extra effort on our part. Here's how the .on version would look:

$('#myTask').on('click', 'li', function (event) {
  $(event.target).remove()
});

Summary:

The difference between .on() and .click() would be that .click() may not work when the DOM elements associated with the .click() event are added dynamically at a later point while .on() can be used in situations where the DOM elements associated with the .on() call may be generated dynamically at a later point.

I won't write your code but what you looking for is something like a jquery dialog

take a look here

jQuery modal-confirmation

$(function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:140,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  });

<div id="dialog-confirm" title="Empty the recycle bin?">
  <p>
    <span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>
    These items will be permanently deleted and cannot be recovered. Are you sure?
  </p>
</div>

If you are deeply in recursion inside recursive method, throwing and catching exception may be an option.

Unlike Return that returns only one level up, exception would break out of recursive method as well into the code that initially called it, where it can be catched.

Adding one more obnoxious alternative to the list:

perl -pe'$.<=1||last' file
# or 
perl -pe'$.<=1||last' < file
# or
cat file | perl -pe'$.<=1||last'

Static indexes and small list?

Don't forget that if the list is small and the indexes don't change, as in your example, sometimes the best thing is to use sequence unpacking:

_,a1,a2,_,_,a3,_ = a

The performance is much better and you can also save one line of code:

 %timeit _,a1,b1,_,_,c1,_ = a
10000000 loops, best of 3: 154 ns per loop 
%timeit itemgetter(*b)(a)
1000000 loops, best of 3: 753 ns per loop
 %timeit [ a[i] for i in b]
1000000 loops, best of 3: 777 ns per loop
 %timeit map(a.__getitem__, b)
1000000 loops, best of 3: 1.42 µs per loop

it works correctly for me:

git branch | xargs git branch -d

git branch | xargs git branch -D

delete all local branches

window.history.pushState({urlPath:'/page1'},"",'/page1')

Only works after page is loaded, and when you will click on refresh it doesn't mean that there is any real URL.

What you should do here is knowing to which URL you are getting redirected when you reload this page. And on that page you can get the conditions by getting the current URL and making all of your conditions.

using flex

 <View style={{ flexDirection: 'row',}}>
                  <Text style={{fontSize: 12, lineHeight: 30, color:'#9394B3' }}>left</Text>
                  <Text style={{ flex:1, fontSize: 16, lineHeight: 30, color:'#1D2359', textAlign:'right' }}>right</Text>
               </View>

I prefer this (below):

public class User
{
    public int Id { get; set; }
    public int? CountryId { get; set; }
    [ForeignKey("CountryId")]
    public virtual Country Country { get; set; }
}

Because EF was creating 2 foreign keys in the database table: CountryId, and CountryId1, but the code above fixed that.

I really like Paul Butcher's answer to this question (he's the writer of Seven Concurrency Models in Seven Weeks):

Although they’re often confused, parallelism and concurrency are different things. Concurrency is an aspect of the problem domain—your code needs to handle multiple simultaneous (or near simultaneous) events. Parallelism, by contrast, is an aspect of the solution domain—you want to make your program run faster by processing different portions of the problem in parallel. Some approaches are applicable to concurrency, some to parallelism, and some to both. Understand which you’re faced with and choose the right tool for the job.

The example by user11617 is incorrect; it will report that the file exists even in cases where it does not, but there was an error of some other sort.

The signature should be Exists(string) (bool, error). And then, as it happens, the call sites are no better.

The code he wrote would better as:

func Exists(name string) bool {
    _, err := os.Stat(name)
    return !os.IsNotExist(err)
}

But I suggest this instead:

func Exists(name string) (bool, error) {
  _, err := os.Stat(name)
  if os.IsNotExist(err) {
    return false, nil
  }
  return err != nil, err
}

You can use Presentation Mode to temporarily increase the font size.

Note: The location of this menu has changed. It's nearer the top.

Enable Presentation Mode with View -> Enter Presentation Mode

I needed to increase the default font size for presentation mode. To do this, open Settings and typed "presentation mode" in the search bar. Under appearance, scroll down to Presentation Mode, and select your preferred font size.

Because I use it frequently, I mapped "toggle presentation mode" to Ctrl-P. Under "Keymap", right-click on "Toggle Presentation mode" and select "Add keyboard shortcut"

Literally press the Control and P keys and then hit OK to enable this.

If you mean File.separator and File.pathSeparator then:

• File.pathSeparator is used to separate individual file paths in a list of file paths. Consider on windows, the PATH environment variable. You use a ; to separate the file paths so on Windows File.pathSeparator would be ;.

• File.separator is either / or \ that is used to split up the path to a specific file. For example on Windows it is \ or C:\Documents\Test

JSESSIONID cookie is created/sent when session is created. Session is created when your code calls request.getSession() or request.getSession(true) for the first time. If you just want to get the session, but not create it if it doesn't exist, use request.getSession(false) -- this will return you a session or null. In this case, new session is not created, and JSESSIONID cookie is not sent. (This also means that session isn't necessarily created on first request... you and your code are in control when the session is created)

Sessions are per-context:

SRV.7.3 Session Scope

HttpSession objects must be scoped at the application (or servlet context) level. The underlying mechanism, such as the cookie used to establish the session, can be the same for different contexts, but the object referenced, including the attributes in that object, must never be shared between contexts by the container.

(Servlet 2.4 specification)

Update: Every call to JSP page implicitly creates a new session if there is no session yet. This can be turned off with the session='false' page directive, in which case session variable is not available on JSP page at all.

Setting the td height to less than the natural height of its content

Since table cells want to be at least big enough to encase their content, if the content has no apparent height, the cells can be arbitrarily resized.

By resizing the cells, we can control the row height.

One way to do this, is to set the content with an absolute position within the relative cell, and set the height of the cell, and the left and top of the content.

The table-layout property

The second table in the snippet above has table-layout: fixed applied, which causes cells to be given equal width, regardless of their content, within the parent.

According to caniuse.com, there are no significant compatibility issues regarding the use of table-layout as of Sept 12, 2019.

Or simply apply width to specific cells as in the third table.

These methods allow the cell containing the effectively sizeless content created by applying position: absolute to be given some arbitrary girth.

Much more simply...

I really should have thought of this from the start; we can manipulate block level table cell content in all the usual ways, and without completely destroying the content's natural size with position: absolute, we can leave the table to figure out what the width should be.

jQuery's .bind() fires in the order it was bound:

When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.

Source: http://api.jquery.com/bind/

Because jQuery's other functions (ex. .click()) are shortcuts for .bind('click', handler), I would guess that they are also triggered in the order they are bound.

I am going to give you a simplistic answer that hopefully will help you with VBA in general. The easiest way to learn how VBA works and how to reference and access elements is to record your macro then edit it in the VBA editor. This is how I learned VBA. It is based on visual basic so all the programming conventions of VB apply. Recording the macro lets you see how to access and do things.

you could use something like this:

var result = 0
Sheets("Sheet1").Select
result = Range("A1").Value * Range("B1").Value
Sheets("Sheet2").Select
Range("D1").Value = result

Alternatively you can also reference a cell using Cells(1,1).Value This way you can set variables and increment them as you wish. I think I am just not clear on exactly what you are trying to do but i hope this helps.

Try instead of assigning dom properties (which is slow) just pass your value as a parameter to function that actually create your handler:

render: function() {
...
<a style={showStyle} onClick={this.removeTag(i)}></a>
...
removeTag = (customAttribute) => (event) => {
    this.setState({inputVal: customAttribute});
}

I added env variables for both GEM_HOME and GEM_PATH to the .htaccess file in my public_html directory (an alias to the public directory in the rails app)

They were not needed before so something must have changed on the hosts side. It got this error after touching the restart.txt file to restart the passenger server.

Got GEM_PATH by:

echo $GEM_PATH

Got the GEM_HOME by:

gem env

I got this script from another StackOverflow question/answer:

SELECT SUM(p.rows) FROM sys.partitions AS p
  INNER JOIN sys.tables AS t
  ON p.[object_id] = t.[object_id]
  INNER JOIN sys.schemas AS s
  ON s.[schema_id] = t.[schema_id]
  WHERE t.name = N'YourTableNameHere'
  AND s.name = N'dbo'
  AND p.index_id IN (0,1);

My table has 500 million records and the above returns in less than 1ms. Meanwhile,

SELECT COUNT(id) FROM MyTable

takes a full 39 minutes, 52 seconds!

They yield the exact same number of rows (in my case, exactly 519326012).

I do not know if that would always be the case.

For Swift 3 and Swift 4:

let htmlFile = Bundle.main.path(forResource: "name_resource", ofType: "html")
let html = try! String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
self.webView.loadHTMLString(html, baseURL: nil)

Don't know how I got to this question, but even if it's many years since this has been asked, I would like to add a quick and simple method I follow and it has never let me down:

var num = response_from_a_function_or_something();

var fixedNum = parseFloat(num).toFixed( 2 );

Yes methods are there for using params. Like answers stated above, in your example it's best to use methods since execution is very light.

Only for reference, in a situation where the method is complex and cost is high, you can cache the results like so:

data() {
    return {
        fullNameCache:{}
    };
}

methods: {
    fullName(salut) {
        if (!this.fullNameCache[salut]) {
            this.fullNameCache[salut] = salut + ' ' + this.firstName + ' ' + this.lastName;
        }
        return this.fullNameCache[salut];
    }
}

note: When using this, watchout for memory if dealing with thousands

It should work the way you intended.

$array = array('value-0', 'value-1', 'value-2', 'value-3', 'value-4', 'value-5' /* … */);
$key = 4;
$value = $array[$key];
echo $value; // value-4

But maybe there is no element with the key 4. If you want to get the fiveth item no matter what key it has, you can use array_slice:

$value = array_slice($array, 4, 1);

You can try following way to check Browser version.

    <!DOCTYPE html>
    <html>
    <body>
    <p>What is the name(s) of your browser?</p>
    <button onclick="myFunction()">Try it</button>
    <p id="demo"></p>
    <script>

    function myFunction() { 
     if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 ) 
    {
        alert('Opera');
    }
    else if(navigator.userAgent.indexOf("Chrome") != -1 )
    {
        alert('Chrome');
    }
    else if(navigator.userAgent.indexOf("Safari") != -1)
    {
        alert('Safari');
    }
    else if(navigator.userAgent.indexOf("Firefox") != -1 ) 
    {
         alert('Firefox');
    }
    else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
    {
      alert('IE'); 
    }  
    else 
    {
       alert('unknown');
    }
    }
    </script>

    </body>
    </html>

And if you need to know only IE Browser version then you can follow below code. This code works well for version IE6 to IE11

<!DOCTYPE html>
<html>
<body>

<p>Click on Try button to check IE Browser version.</p>

<button onclick="getInternetExplorerVersion()">Try it</button>

<p id="demo"></p>

<script>
function getInternetExplorerVersion() {
   var ua = window.navigator.userAgent;
        var msie = ua.indexOf("MSIE ");
        var rv = -1;

        if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer, return version number
        {               

            if (isNaN(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))))) {
                //For IE 11 >
                if (navigator.appName == 'Netscape') {
                    var ua = navigator.userAgent;
                    var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
                    if (re.exec(ua) != null) {
                        rv = parseFloat(RegExp.$1);
                        alert(rv);
                    }
                }
                else {
                    alert('otherbrowser');
                }
            }
            else {
                //For < IE11
                alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
            }
            return false;
        }}

I think I have a better answer.

new Timestamp(longEpochTime).toLocalDateTime();

$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";

Just leaving the value of the AI primary key NULL will assign an auto incremented value.

Meanwhile, all the values above will only restrict the values to integer, so i use

/^[1-9][0-9\.]{0,15}$/

to allow float values too.

FYI you can also get this error if EF Migrations tries to run with no Db configured, for example in a Test Project.

Chased this for hours before I figured out that it was erroring on a query, but, not because of the query but because it was when Migrations kicked in to try to create the Db.

null is a special value meaning "no value". null is a special object because typeof null returns 'object'.

On the other hand, undefined means that the variable has not been declared, or has not been given a value.

Consider also .attr()

$("#roommate_but").attr("disabled", true); worked for me.

The easiest way would be to delete the plugins folder. Run this command: cordova prepare But, before you run it, you can check each plugin's version that you think would work for your build on Cordova's plugin repository website, and then you should modify the config.xml file, manually. Use upper carrots, "^" in the version field of the universal modeling language file, "config," to indicate that you want the specified plugin to update to the latest version in the future (the next time you run the command.)

From my experience ten minutes ago this situation can happen where there are more than one category but with a lot of NAs. Taking the Kaggle Houseprice Dataset as example, if you loaded data and run a simple regression,

train.df = read.csv('train.csv')
lm1 = lm(SalePrice ~ ., data = train.df)

you will get same error. I also tried testing the number of levels of each factor, but none of them says it has less than 2 levels.

cols = colnames(train.df)
for (col in cols){
  if(is.factor(train.df[[col]])){
    cat(col, ' has ', length(levels(train.df[[col]])), '\n')
  }
}

So after a long time I used summary(train.df) to see details of each col, and removed some, and it finally worked:

train.df = subset(train.df, select=-c(Id, PoolQC,Fence, MiscFeature, Alley, Utilities))
lm1 = lm(SalePrice ~ ., data = train.df)

and removing any one of them the regression fails to run again with same error (which I have tested myself).

And above attributes generally have 1400+ NAs and 10 useful values, so you might want to remove these garbage attributes, even they have 3 or 4 levels. I guess a function counting how many NAs in each column will help.

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

You can use arrows:

arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)

input[type='checkbox'][disabled][checked] {
width:0px; height:0px;
}
input[type='checkbox'][disabled][checked]:after {
 content:'\e013'; position:absolute; 
 margin-top:-10px;
 opacity: 1 !important;
 margin-left:-5px;
 font-family: 'Glyphicons Halflings';
 font-style: normal;
 font-weight: normal;
}

The most likely reason would be that something else is using port 80. (Often this can be Skype, IIS, etc.)

GNU GetOpt.

A simple example using GetOpt:

// C/C++ Libraries:
#include <string>
#include <iostream>
#include <unistd.h>

// Namespaces:
using namespace std;

int main(int argc, char** argv) {
    int opt;
    bool flagA = false;
    bool flagB = false;

    // Shut GetOpt error messages down (return '?'): 
    opterr = 0;

    // Retrieve the options:
    while ( (opt = getopt(argc, argv, "ab")) != -1 ) {  // for each option...
        switch ( opt ) {
            case 'a':
                    flagA = true;
                break;
            case 'b':
                    flagB = true;
                break;
            case '?':  // unknown option...
                    cerr << "Unknown option: '" << char(optopt) << "'!" << endl;
                break;
        }
    }

    // Debug:
    cout << "flagA = " << flagA << endl;
    cout << "flagB = " << flagB << endl;

    return 0;
}

You can also use optarg if you have options that accept arguments.

JSP is s presentation framework, and is generally not supposed to contain any program logic in it. As skaffman suggested, use pure servlets, or any MVC web framework in order to achieve what you want.

   <script type="text/javascript"> // if site open in iframe then redirect to main site
        $(function(){
             if(window.top.location != window.self.location)
             {
                top.window.location.href = window.self.location;
             }
        });
    </script>
