You can use the WooCommerce Layered Nav widget, which allows you to use different sets of attributes as filters for products. Here's the "official" description:

Shows a custom attribute in a widget which lets you narrow down the list of products when viewing product categories.

If you look into plugins/woocommerce/widgets/widget-layered_nav.php, you can see the way it operates with the attributes in order to set filters. The URL then looks like this:

http://yoursite.com/shop/?filtering=1&filter_min-kvadratura=181&filter_max-kvadratura=108&filter_obem-ohlajdane=111

... and the digits are actually the id-s of the different attribute values, that you want to set.

This worked for me:

   Espresso.onView(ViewMatchers.withId(R.id.radiobutton)).check(ViewAssertions.matches(isChecked()))

This also involves iterating, but this is much better than concatenating strings as they are very very costly.

public String openFileToString(String fileName)
{
    StringBuilder s = new StringBuilder(_bytes.length);

    for(int i = 0; i < _bytes.length; i++)
    {
        s.append((char)_bytes[i]);
    }

    return s.toString();    
}

I know this is a little bit of necromancy, but you should use the Android AccountManager. It's purpose-built for this scenario. It's a little bit cumbersome but one of the things it does is invalidate the local credentials if the SIM card changes, so if somebody swipes your phone and throws a new SIM in it, your credentials won't be compromised.

This also gives the user a quick and easy way to access (and potentially delete) the stored credentials for any account they have on the device, all from one place.

SampleSyncAdapter is an example that makes use of stored account credentials.

Sometimes, the methods in the other answers don't work. In my case, I'm generating a signature with my RSA private key and the result is NSData. I found that this seems to work:

Objective-C

NSData *signature;
NSString *signatureString = [signature base64EncodedStringWithOptions:0];

Swift

let signatureString = signature.base64EncodedStringWithOptions(nil)

For a script working with Python 2 (tested versions 2.7.3 and 2.6.8) and Python 3 (3.2.3 and 3.3.2+) try:

    from urllib.request import urlopen
except ImportError:

You may find useful this modification of date object, which is smaller than any library and is easily extendable to support different formats:

NOTE:

• It uses Object.keys() which is undefined in older browsers so you may need implement polyfill from given link.

CODE

Date.prototype.format = function(format) {
    // set default format if function argument not provided
    format = format || 'YYYY-MM-DD hh:mm';

    var zeropad = function(number, length) {
            number = number.toString();
            length = length || 2;
            while(number.length < length)
                number = '0' + number;
            return number;
        },
        // here you can define your formats
        formats = {
            YYYY: this.getFullYear(),
            MM: zeropad(this.getMonth() + 1),
            DD: zeropad(this.getDate()),
            hh: zeropad(this.getHours()),
            mm: zeropad(this.getMinutes())
        },
        pattern = '(' + Object.keys(formats).join(')|(') + ')';

    return format.replace(new RegExp(pattern, 'g'), function(match) {
        return formats[match];
    });
};

USE

var now = new Date;
console.log(now.format());
// outputs: 2015-02-09 11:47
var yesterday = new Date('2015-02-08');
console.log(yesterday.format('hh:mm YYYY/MM/DD'));
// outputs: 00:00 2015/02/08

I got a similar error with '/' operand while processing images. I discovered the folder included a text file created by the 'XnView' image viewer. So, this kind of error occurs when some object is not the kind of object expected.

I had a similar issue, I was sending a POST request (using RESTClient plugin for Firefox) with data in the request body and was receiving the same message.

In my case this happened because I was trying to use HTTPS protocol in a local tomcat instance where HTTPS was not configured.

event.key === "Backspace"

More recent and much cleaner: use event.key. No more arbitrary number codes!

note.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace") {
        // Do something
    }
});

android:inputType="number" or android:inputType="phone". You can keep this. You will get the keyboard containing numbers. For further details on different types of keyboard, check this link.

I think it is possible only if you create your own soft keyboard. Or try this android:inputType="number|textVisiblePassword. But it still shows other characters. Besides you can keep android:digits="0123456789" to allow only numbers in your edittext. Or if you still want the same as in image, try combining two or more features with | separator and check your luck, but as per my knowledge you have to create your own keypad to get exactly like that..

Another reason why you might get errors like "relation already exists" is if the DROP command did not execute correctly.

One reason this can happen is if there are other sessions connected to the database which you need to close first.

If the service is running via brew, you can stop it using the following command:

brew services stop mongodb

It depends which style from the div you need. Is this a background style which was defined in CSS or background style which was added through javascript(inline) to the current node?

In case of CSS style, you should use computed style. Like you do in getStyle().

With inline style you should use node.style reference: x.style.backgroundColor;

Also notice, that you pick the style by using camelCase/non hyphen reference, so not background-color, but backgroundColor;

This kind of thing is not easy. Here is a method that calls a static method:

public static Object callStaticMethod(

    final Class<?> clazz,

    final String methodName,
    // optional method parameters
    final Object... parameters) throws Exception{
    for(final Method method : clazz.getMethods()){
        if(method.getName().equals(methodName)){
            final Class<?>[] paramTypes = method.getParameterTypes();
            if(parameters.length != paramTypes.length){
                continue;
            }
            boolean compatible = true;
            for(int i = 0; i < paramTypes.length; i++){
                final Class<?> paramType = paramTypes[i];
                final Object param = parameters[i];
                if(param != null && !paramType.isInstance(param)){
                    compatible = false;
                    break;
                }

            }
            if(compatible){
                return method.invoke(/* static invocation */null,

            }

}

Update: Wait, I just saw the gwt tag on the question. You can't use reflection in GWT

Your data may not be what you expect -- it seems you're expecting, but not getting, floats.

A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:

for i in range(0,N):
    w=f[i].split()
    l1=w[1:8]
    l2=w[8:15]
    try:
      list1=[float(x) for x in l1]
      list2=[float(x) for x in l2]
    except ValueError, e:
      # report the error in some way that is helpful -- maybe print out i
    result=stats.ttest_ind(list1,list2)
    print result[1]

Angularjs 1.1.4 has now introduced the ng-animate directive to help animating different elements, in particular ng-view.

You can also watch the video about this new featue

UPDATE as of angularjs 1.2, the way animations work has changed drastically, most of it is now controlled with CSS, without having to setup javascript callbacks, etc.. You can check the updated tutorial on Year Of Moo. @dfsq pointed out in the comments a nice set of examples.

/etc/services is only advisory, it's a listing of well-known ports. It doesn't mean that anything is actually running on that port or that the named service will run on that port.

In PostgreSQL's case it's typical to use port 5432 if it is available. If it isn't, most installers will choose the next free port, usually 5433.

You can see what is actually running using the netstat tool (available on OS X, Windows, and Linux, with command line syntax varying across all three).

This is further complicated on Mac OS X systems by the horrible mess of different PostgreSQL packages - Apple's ancient version of PostgreSQL built in to the OS, Postgres.app, Homebrew, Macports, the EnterpriseDB installer, etc etc.

What ends up happening is that the user installs Pg and starts a server from one packaging, but uses the psql and libpq client from a different packaging. Typically this occurs when they're running Postgres.app or homebrew Pg and connecting with the psql that shipped with the OS. Not only do these sometimes have different default ports, but the Pg that shipped with Mac OS X has a different default unix socket path, so even if the server is running on the same port it won't be listening to the same unix socket.

Most Mac users work around this by just using tcp/ip with psql -h localhost. You can also specify a port if required, eg psql -h localhost -p 5433. You might have multiple PostgreSQL instances running so make sure you're connecting to the right one by using select version() and SHOW data_directory;.

You can also specify a unix socket directory; check the unix_socket_directories setting of the PostgreSQL instance you wish to connect to and specify that with psql -h, e.g.psql -h /tmp.

A cleaner solution is to correct your system PATH so that the psql and libpq associated with the PostgreSQL you are actually running is what's found first on the PATH. The details of that depend on your Mac OS X version and which Pg packages you have installed. I don't use Mac and can't offer much more detail on that side without spending more time than is currently available.

The var_dump function displays structured information about variables/expressions including its type and value. Arrays are explored recursively with values indented to show structure. It also shows which array values and object properties are references.

The print_r() displays information about a variable in a way that's readable by humans. array values will be presented in a format that shows keys and elements. Similar notation is used for objects.

Example:

$obj = (object) array('qualitypoint', 'technologies', 'India');

var_dump($obj) will display below output in the screen.

object(stdClass)#1 (3) {
 [0]=> string(12) "qualitypoint"
 [1]=> string(12) "technologies"
 [2]=> string(5) "India"
}

And, print_r($obj) will display below output in the screen.

stdClass Object ( 
 [0] => qualitypoint
 [1] => technologies
 [2] => India
)

If you want to temporarily get rid of these console errors (like I did) you can install the extension here: https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd/reviews?hl=en

I left a review asking for a fix. You can also do a bug report via the extension (after you install it) here. Instructions for doing so are here: https://support.google.com/chromecast/answer/3187017?hl=en

I hope Google gets on this. I need my console to show my errors, etc. Not theirs.

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

I was experiencing this problem on Samsung devices (fine on others). like zyamys suggested in his/her comment, I added the manifest.permission line but in addition to rather than instead of the original line, so:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.Manifest.permission.READ_PHONE_STATE" />

I'm targeting API 22, so don't need to explicitly ask for permissions.

A better idea,

if you want to put the error message just beneath the text field, you can do like this

.row.spacer20top
  .col-sm-6.form-group
    = f.label :first_name, "*Your First Name:"
    = f.text_field :first_name, :required => true, class: "form-control"
    = f.error_message_for(:first_name)

What is error_message_for?
--> Well, this is a beautiful hack to do some cool stuff

Note: Bootstrap variables used here

If your row length is a compile time constant, C++11 allows

auto arr2d = new int [nrows][CONSTANT];

See this answer. Compilers like gcc that allow variable-length arrays as an extension to C++ can use new as shown here to get fully runtime-variable array dimension functionality like C99 allows, but portable ISO C++ is limited to only the first dimension being variable.

Another efficient option is to do the 2d indexing manually into a big 1d array, as another answer shows, allowing the same compiler optimizations as a real 2D array (e.g. proving or checking that arrays don't alias each other / overlap).

Otherwise, you can use an array of pointers to arrays to allow 2D syntax like contiguous 2D arrays, even though it's not an efficient single large allocation. You can initialize it using a loop, like this:

int** a = new int*[rowCount];
for(int i = 0; i < rowCount; ++i)
    a[i] = new int[colCount];

The above, for colCount= 5 and rowCount = 4, would produce the following:

Don't forget to delete each row separately with a loop, before deleting the array of pointers. Example in another answer.

Here is how to do it in Unity:

(Modified answer from @markmuetz so be sure to upvote his answer)

int[,] rawNodes = new int[,]
{
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 },
    { 0, 0, 0, 0, 0, 0 }
};

private void Start()
{
    int rowLength = rawNodes.GetLength(0);
    int colLength = rawNodes.GetLength(1);
    string arrayString = "";
    for (int i = 0; i < rowLength; i++)
    {
        for (int j = 0; j < colLength; j++)
        {
            arrayString += string.Format("{0} ", rawNodes[i, j]);
        }
        arrayString += System.Environment.NewLine + System.Environment.NewLine;
    }

    Debug.Log(arrayString);
}

To get substring

1. find position of "sp"

2. cut string with array-logical

And in my case it was simple: I used 'Add WCF Service' wizard in Visual Studio, which automatically created corresponding sections in app.config. Then I went on reading How to: Host a WCF Service in a Managed Application. The problem was: I didn't need to specify the url to run the web service.

Replace:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))

With:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService))

And the error is gone.

Generic idea: if you provide base address as a param and specify it in config, you get this error. Most probably, that's not the only way to get the error, thou.

If you are using the latest versions of macOS, then you cannot use ~/.bash_profile to export your environment variable since the bash shell is deprecated in the latest version of macOS.

• Run /usr/libexec/java_home in your terminal and you will get things like /Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home
• Add export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home to .zshrc

Another solution I found was this, if you have multiple classes and are dealing with radio buttons while clicking on the label.

$('.btn').on('click', function(e) {
    e.preventDefault();

    // Hack - Stop Double click on Radio Buttons
    if (e.target.tagName != 'INPUT') {
        // Not a input, check to see if we have a radio
        $(this).find('input').attr('checked', 'checked').change();
    }
});

I just encountered this issue and would recommend csvsql (releases) for bulk imports to Postgres. To perform a bulk insert you'd simply createdb and then use csvsql, which connects to your database and creates individual tables for an entire folder of CSVs.

$ createdb test 
$ csvsql --db postgresql:///test --insert examples/*.csv

As of right now that feature is not supported, however if this is something that bothers you an alternative would be in your package.json...

"scripts": {
  "start": "ng serve --host foo.bar --port 80"
}

This way you can simply run npm start

Another option if you want to do this across multiple projects is to create an alias, which you can potentially name ngserve which will execute your above command.

The simplest solution to call your function with delay is:

function executeWithDelay(anotherFunction) {
    setTimeout(anotherFunction, delayInMilliseconds);
}

Alternatively, if you want to solely obtain the current directory of the current NodeJS script, you could try something simple like this. Note that this will not work in the Node CLI itself:

var fs = require('fs'),
    path = require('path');

var dirString = path.dirname(fs.realpathSync(__filename));

// output example: "/Users/jb/workspace/abtest"
console.log('directory to start walking...', dirString);

Your attempts to construct different strings using concatenation will fail as it's being performed at compile-time. Both of those maps have a single pair; each pair will have "foo" and "barbar" as the key/value, both using the same string reference.

Assuming you really want to compare the sets of values without any reference to keys, it's just a case of:

Set<String> values1 = new HashSet<>(map1.values());
Set<String> values2 = new HashSet<>(map2.values());
boolean equal = values1.equals(values2);

It's possible that comparing map1.values() with map2.values() would work - but it's also possible that the order in which they're returned would be used in the equality comparison, which isn't what you want.

Note that using a set has its own problems - because the above code would deem a map of {"a":"0", "b":"0"} and {"c":"0"} to be equal... the value sets are equal, after all.

If you could provide a stricter definition of what you want, it'll be easier to make sure we give you the right answer.

Root cause: Corrupted user profile of user account used to start database

The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:

SQLSVCACCOUNT:                 NT AUTHORITY\SYSTEM

According to the link provided by @royki:

The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.

This would explain why other respondents had success after changing to different accounts:

• bmjjr suggests changing to "NT AUTHORITY\NETWORK SERVICE"
• comments to @bmjjr indicate different accounts "I used NT AUTHORITY\LOCAL SERVICE. That helped too"
• @Julio Nobre had success with "NT Authority\System "

Fix: reset the corrupt user profile

To fix the user profile that's causing the error, follow the steps listed KB947215.

The main steps from KB947215 are summarized as follows:-

1. Open regedit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

3. Navigate to the SID for the corrupted profile

   To find the SID, click on each SID GUID, review the value for the ProfileImagePath value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:

The main system account SIDs of interest are:

SID          Name               Also Known As
S-1-5-18     Local System       NT AUTHORITY\SYSTEM
S-1-5-19     LocalService       NT AUTHORITY\LOCAL SERVICE
S-1-5-20     NetworkService     NT AUTHORITY\NETWORK SERVICE

For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

4. If there are two entries (e.g. with a .bak) at the end for the SID in question, or the SID in question ends in .bak, ensure to follow carefully the steps in the KB947215 article.
5. Reset the values for RefCount and State to be 0.
6. Reboot.
7. Retry the SQL Server installation.

Extremely fast

I analyse current solutions and propose 2 new (F and G presented in details section) one which are extremely fast for small and medium arrays

Performance

Today 2020.11.13 I perform tests on MacOs HighSierra 10.13.6 on Chrome v86, Safari v13.1.2 and Firefox v82 for chosen solutions

Results

For all browsers

• solutions based on while-pop-unshift (F,G) are (extremely) fastest on all browsers for small and medium size arrays. For arrays with 50000 elements this solutions slows down on Chrome
• solutions C,D for arrays 500000 breaks: "RangeError: Maximum call stack size exceeded
• solution (E) is slowest

Details

I perform 2 tests cases:

• when arrays have 10 elements - you can run it HERE
• when arrays have 10k elements - you can run it HERE

Below snippet presents differences between solutions A, B, C, D, E, F(my), G(my), H, I

The keyboard seems to pop up when the EditText gains focus. To prevent this, set focusable to false:

<EditText
    ...
    android:focusable="false"
    ... />

This behavior can vary on different manufacturers' Android OS flavors, but on the devices I've tested I have found this to to be sufficient. If the keyboard still pops up, using hints instead of text seems to help as well:

myEditText.setText("My text");    // instead of this...
myEditText.setHint("My text");    // try this

Once you've done this, your on click listener should work as desired:

myEditText.setOnClickListener(new OnClickListener() {...});

Probably, the easiest way to achieve this is to simply add the reference to the assembly and then (manually) patch the textual representation of the reference in the corresponding Visual Studio project file (extension .csproj) such that it becomes relative.

I've done this plenty of times in VS 2005 without any problems.

Using the chronic gem:

class MyModel < ActiveRecord::Base
  validate :valid_date?

  def valid_date?
    unless Chronic.parse(from_date)
      errors.add(:from_date, "is missing or invalid")
    end
  end

end

Quick fix that worked for me:

Right click on project->"Open Module Settings"->Build Tools Version change to: 22.0.1

After searching a lot I find out that it is possible to create a new folder from the web interface, but it would require you to have at least one file within the folder when creating it.

When using the normal way of creating new files through the web interface, you can type in the folder into the file name to create the file within that new directory.

For example, if I would like to create the file filename.md in a series of sub-folders, I can do this (taken from the GitHub blog):

So Soumyaansh's Revo Uninstaller Pro fix worked for me :) ( After 2 days of troubleshooting other options {screams internally 😀} ).

I did run into the an issue with his method though, "Could not find a suitable SDK to target" even though I selected to install Visual Studio with custom settings and selected the SDK I wanted to install. You may need to download the Windows 10 Standalone SDK to resolved this, in order to develop UWP apps if you see this same error after reinstalling Visual Studio.

To do this

1. Uninstall any Windows 10 SDKs that me on the system (the naming schem for them looks like Windows 10 SDK (WINDOWS_VERSION_NUMBER_HERE) -> Windows 10 SDK (14393) etc . . .). If there are no SDKs on your system go to step 2!
2. All that's left is to download the SDKs you want by Checking out the SDK Archive for all available SDKs and you should be good to go in developing for the UWP!

I wrote a tutorial about this a while ago.

The most important point is the "Site URL":

Site URL: http://localhost/app_name/

Where the folder structure is something like:

app_name
¦   index.php
¦
+---canvas
¦   ¦   index.php
¦   ¦
¦   +---css
¦           main.css
¦           reset.css
¦
+---src
        facebook.php
        fb_ca_chain_bundle.crt

EDIT:
Kavya: how does the FB server recognize my localhost even without an IP or port??

I don't think this has anything to do with Facebook, I guess since the iframe src parameter is loaded from client-side it'll treat your local URL as if you put it directly on your browser.

For example have a file on your online server with content (e.g. online.php):

<iframe src="http://localhost/test.php" width="100%" height="100%">
    <p>Not supported!</p>
</iframe>

And on your localhost root directory, have the file test.php:

<?php echo "Hello from Localhost!"; ?>

Now visit http://your_domain.com/online.php you will see your localhost file's content!

This is why realtime subscriptions and deauthorize callbacks (just to mention) won't work with localhost URLs! because Facebook will ping (send http requests) to these URLs but obviously Facebook server won't translate those URLs to yours!

Oracle's error message should be somewhat longer. It usually looks like this:

ORA-00001: unique constraint (TABLE_UK1) violated

The name in parentheses is the constrait name. It tells you which constraint was violated.

This should work in pretty much any browser...

function getByClass (className, parent) {
  parent || (parent=document);
  var descendants=parent.getElementsByTagName('*'), i=-1, e, result=[];
  while (e=descendants[++i]) {
    ((' '+(e['class']||e.className)+' ').indexOf(' '+className+' ') > -1) && result.push(e);
  }
  return result;
}

You should be able to use it like this:

function replaceInClass (className, content) {
  var nodes = getByClass(className), i=-1, node;
  while (node=nodes[++i]) node.innerHTML = content;
}

As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability:

/// <summary>
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// </summary>
/// <param name="url">The URL helper.</param>
/// <param name="actionName">The name of the action method.</param>
/// <param name="controllerName">The name of the controller.</param>
/// <param name="routeValues">The route values.</param>
/// <returns>The absolute URL.</returns>
public static string AbsoluteAction(this UrlHelper url,
    string actionName, string controllerName, object routeValues = null)
{
    string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

    return url.Action(actionName, controllerName, routeValues, scheme);
}

You can then simply use it like that in your view:

@Url.AbsoluteAction("Action", "Controller")

This can also be done in CSS, for more customisability:

.hoverable {
  position: relative;
}

.hoverable>.hoverable__tooltip {
  display: none;
}

.hoverable:hover>.hoverable__tooltip {
  display: inline;
  position: absolute;
  top: 1em;
  left: 1em;
  background: #888;
  border: 1px solid black;
}

<div class="hoverable">
  <span class="hoverable__main">Main text</span>
  <span class="hoverable__tooltip">Hover text</span>
</div>

(Obviously, styling can be improved)

Only thing i found is the BetterSource extension for Safari this will show you the manipulated source of the document only downside is nothing remotely like it for Firefox

String file = "/path/to/your/file.txt";

try {

    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
    String line;
    // Uncomment the line below if you want to skip the fist line (e.g if headers)
    // line = br.readLine();

    while ((line = br.readLine()) != null) {

        // do something with line

    }
    br.close();

} catch (IOException e) {
    System.out.println("ERROR: unable to read file " + file);
    e.printStackTrace();   
}

var arr3 = new arraylist();
for(int i=0, j=0, k=0; i<arr1.size()+arr2.size(); i++){
    if(i&1)
        arr3.add(arr1[j++]);
    else
        arr3.add(arr2[k++]);
}

as you say, "the names and numbers beside each other".

You can write a directive to listen the change event on the input and reset the value to the min value if it is too low. StackBlitz

@HostListener('change') onChange() {
  const min = +this.elementRef.nativeElement.getAttribute('min');

  if (this.valueIsLessThanMin(min, +this.elementRef.nativeElement.value)) {
    this.renderer2.setProperty(
      this.elementRef.nativeElement,
      'value',
      min + ''
    );
  }
}

Also listen for the ngModelChange event to do the same when the form value is set.

@HostListener('ngModelChange', ['$event'])
onModelChange(value: number) {
  const min = +this.elementRef.nativeElement.getAttribute('min');
  if (this.valueIsLessThanMin(min, value)) {
    const formControl = this.formControlName
      ? this.formControlName.control
      : this.formControlDirective.control;

    if (formControl) {
      if (formControl.updateOn === 'change') {
        console.warn(
          `minValueDirective: form control ${this.formControlName.name} is set to update on change
          this can cause issues with min update values.`
        );
      }
      formControl.reset(min);
    }
  }
}

Full code:

import {
  Directive,
  ElementRef,
  HostListener,
  Optional,
  Renderer2,
  Self
} from "@angular/core";
import { FormControlDirective, FormControlName } from "@angular/forms";

@Directive({
  // tslint:disable-next-line: directive-selector
  selector: "input[minValue][min][type=number]"
})
export class MinValueDirective {
  @HostListener("change") onChange() {
    const min = +this.elementRef.nativeElement.getAttribute("min");

    if (this.valueIsLessThanMin(min, +this.elementRef.nativeElement.value)) {
      this.renderer2.setProperty(
        this.elementRef.nativeElement,
        "value",
        min + ""
      );
    }
  }

  // if input is a form control validate on model change
  @HostListener("ngModelChange", ["$event"])
  onModelChange(value: number) {
    const min = +this.elementRef.nativeElement.getAttribute("min");
    if (this.valueIsLessThanMin(min, value)) {
      const formControl = this.formControlName
        ? this.formControlName.control
        : this.formControlDirective.control;

      if (formControl) {
        if (formControl.updateOn === "change") {
          console.warn(
            `minValueDirective: form control ${
              this.formControlName.name
            } is set to update on change
              this can cause issues with min update values.`
          );
        }
        formControl.reset(min);
      }
    }
  }

  constructor(
    private elementRef: ElementRef<HTMLInputElement>,
    private renderer2: Renderer2,
    @Optional() @Self() private formControlName: FormControlName,
    @Optional() @Self() private formControlDirective: FormControlDirective
  ) {}

  private valueIsLessThanMin(min: any, value: number): boolean {
    return typeof min === "number" && value && value < min;
  }
}

Make sure to use this with the form control set to updateOn blur or the user won't be able to enter a +1 digit number if the first digit is below the min value.

 this.formGroup = this.formBuilder.group({
    test: [
      null,
      {
        updateOn: 'blur',
        validators: [Validators.min(5)]
      }
    ]
  });

For Windows, if directory is not empty, and you have read-only files or you get errors like

• Access is denied
• The process cannot access the file because it is being used by another process

Try this, os.system('rmdir /S /Q "{}"'.format(directory))

It's equivalent for rm -rf in Linux/Mac.

If you are using Toolbar, I was facing the same issue. I solved by following these two steps

1. In the AndroidManifest.xml

<activity android:name=".activity.SecondActivity" android:parentActivityName=".activity.MainActivity"/>

2. In the SecondActivity, add these...

Toolbar toolbar = findViewById(R.id.second_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

The correct way to do this is:

String[] stockArr = stock_list.toArray(new String[stock_list.size()]);

I'd like to add to the other great answers here and explain how you could have used the Javadocs to answer your question.

The Javadoc for toArray() (no arguments) is here. As you can see, this method returns an Object[] and not String[] which is an array of the runtime type of your list:

public Object[] toArray()

Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.

Right below that method, though, is the Javadoc for toArray(T[] a). As you can see, this method returns a T[] where T is the type of the array you pass in. At first this seems like what you're looking for, but it's unclear exactly why you're passing in an array (are you adding to it, using it for just the type, etc). The documentation makes it clear that the purpose of the passed array is essentially to define the type of array to return (which is exactly your use case):

public <T> T[] toArray(T[] a)

Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection. If the collection fits in the specified array with room to spare (i.e., the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

This implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). Then, it iterates over the collection, storing each object reference in the next consecutive element of the array, starting with element 0. If the array is larger than the collection, a null is stored in the first location after the end of the collection.

Of course, an understanding of generics (as described in the other answers) is required to really understand the difference between these two methods. Nevertheless, if you first go to the Javadocs, you will usually find your answer and then see for yourself what else you need to learn (if you really do).

Also note that reading the Javadocs here helps you to understand what the structure of the array you pass in should be. Though it may not really practically matter, you should not pass in an empty array like this:

String [] stockArr = stockList.toArray(new String[0]);  

Because, from the doc, this implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). There's no need for the extra overhead in creating a new array when you could easily pass in the size.

As is usually the case, the Javadocs provide you with a wealth of information and direction.

Hey wait a minute, what's reflection?

Here is the simplest way given

 <script type="text/javascript">

        $(document).ready(function () {
            $("#chk_selall").change("click", function () {

                if (this.checked)
                {
                    //do something
                }
                if (!this.checked)
                {
                    //do something

                }

            });

        });

    </script>

Instead of using local imports, you may import the entire module instead of the particular object. Then, in your app module, call mod_login.mod_login

app.py

from flask import Flask
import mod_login

# ...

do_stuff_with(mod_login.mod_login)

mod_login.py

from app import app

mod_login = something

I had similar problem (in bash terminal command was working correctly but zsh showed command not found error)

Solution:

just paste whatever you were earlier pasting in ~/.bashrc to:

~/.zshrc

No, you can only get to the interior color of a cell by using a Macro. I am afraid. It's really easy to do (cell.interior.color) so unless you have a requirement that restricts you from using VBA, I say go for it.

The CLSID you describe is for the Microsoft.Office.Interop.Excel.ApplicationClass. This class basically launches excel.exe through InprocServer32. If you don't have it installed then it will return the error message you received above.

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

what about this?

top -c -p <PID>

The string $chain is in the same character encoding as the characters in the array - it's possible, even likely, that the $first_name string is in a different encoding, and so those characters don't match. You might want to try using the multibyte string functions instead.

Try mb_convert_encoding. You might also want to try using HTML_ENTITIES as the to_encoding parameter, then you don't need to worry about how the characters will get converted - it will be very predictable.

Assuming your input to this script is in UTF-8, probably not a bad place to start...

$first_name = mb_convert_encoding($first_name, "HTML-ENTITIES", "UTF-8"); 

If you can't just use filter join but need to perform some operations on the array's entry:

{% for entry in array %}
User {{ entry.attribute1 }} has id {{ entry.attribute2 }}
{% if not loop.last %}, {% endif %}

In the list of arguments, each entry must be on its own. Using

output = subprocess.check_output(["ping", "-c","2", "-W","2", "1.1.1.1"])

should fix your problem.

A much simpler alternative is to get the information from the connection object itself. For example:

IDbConnection connection = new SqlConnection(connectionString);
var dbName = connection.Database;

Similarly you can get the server name as well from the connection object.

DbConnection connection = new SqlConnection(connectionString);
var server = connection.DataSource;

I rather use Virtualenv to install such packages rather than the entire system, saves time and effort rather than building from source.

I use virtualenvwrapper

Windows user can download

pip install virtualenvwrapper-win

Linux follow

pip install opencv-python

The canvas element provides a toDataURL method which returns a data: URL that includes the base64-encoded image data in a given format. For example:

var jpegUrl = canvas.toDataURL("image/jpeg");
var pngUrl = canvas.toDataURL(); // PNG is the default

Although the return value is not just the base64 encoded binary data, it's a simple matter to trim off the scheme and the file type to get just the data you want.

The toDataURL method will fail if the browser thinks you've drawn to the canvas any data that was loaded from a different origin, so this approach will only work if your image files are loaded from the same server as the HTML page whose script is performing this operation.

For more information see the MDN docs on the canvas API, which includes details on toDataURL, and the Wikipedia article on the data: URI scheme, which includes details on the format of the URI you'll receive from this call.

With AngularJS :

angular.element('#Element')[0].focus();

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

...and when I got one how to process it (do I need to use Fourier Transform like it was instructed in the above post)?

If you want a "tap" then I think you are interested in amplitude more than frequency. So Fourier transforms probably aren't useful for your particular goal. You probably want to make a running measurement of the short-term (say 10 ms) amplitude of the input, and detect when it suddenly increases by a certain delta. You would need to tune the parameters of:

• what is the "short-term" amplitude measurement
• what is the delta increase you look for
• how quickly the delta change must occur

Although I said you're not interested in frequency, you might want to do some filtering first, to filter out especially low and high frequency components. That might help you avoid some "false positives". You could do that with an FIR or IIR digital filter; Fourier isn't necessary.

import requests
# assume sending two files
url = "put ur url here"
f1 = open("file 1 path", 'rb')
f2 = open("file 2 path", 'rb')
response = requests.post(url,files={"file1 name": f1, "file2 name":f2})
print(response)

There isn't any graph api for this, you need to use facebook xmpp chat api to send the message, good news is: I have made a php class which is too easy to use,call a function and message will be sent, its open source, check it out: facebook message api php the description says its a closed source but the it was made open source later, see the first comment, you can clone from github. It's a open source now.

You can update the angular with command 'ng update --all'. It will take time but make sure your all components are up to date.

The break keyword in C++ only terminates the most-nested enclosing iteration or switch statement. Thus, you couldn't break out of the while (true) loop directly within the switch statement; however you could use the following code, which I think is an excellent pattern for this type of problem:

for (; msg->state != DONE; msg = next_message()) {
    switch (msg->state) {
    case MSGTYPE:
        //...
        break;

    //...
    }
}

If you needed to do something when msg->state equals DONE (such as run a cleanup routine), then place that code immediately after the for loop; i.e. if you currently have:

while (true) {
    switch (msg->state) {
    case MSGTYPE:
        //... 
        break;

    //...

    case DONE:
        do_cleanup();
        break;
    }

    if (msg->state == DONE)
        break;

    msg = next_message();
}

Then use instead:

for (; msg->state != DONE; msg = next_message()) {
    switch (msg->state) {
    case MSGTYPE:
        //...
        break;

    //...
    }
}

assert(msg->state == DONE);
do_cleanup();

Every answer uses .next() or uses .beforeFirst() and then .next(). But why not this:

result.first();

So You just set the pointer to the first record and go from there. It's available since java 1.2 and I just wanted to mention this for anyone whose ResultSet exists of one specific record.

My problem was running out of memory. Digital ocean has great instruction for adding swap memory for Ubuntu: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

This solved the issue and enabled me to restart the Mysql that otherwise would not start.

Here is my layout:

    <HorizontalScrollView
        android:id="@+id/horizontalScrollView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/padding" >

       <LinearLayout
        android:id="@+id/shapeLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" >
        </LinearLayout>
    </HorizontalScrollView>

And I populate it in the code with dynamic check-boxes.

If you are using a SpringBoot application it's as simple as

ScheduledProcess

@Log
@Component
public class ScheduledProcess {

    @Scheduled(fixedRate = 5000)
    public void run() {
        log.info("this runs every 5 seconds..");
    }

}

Application.class

@SpringBootApplication
// ADD THIS ANNOTATION TO YOUR APPLICATION CLASS
@EnableScheduling
public class SchedulingTasksApplication {

    public static void main(String[] args) {
        SpringApplication.run(SchedulingTasksApplication.class);
    }
}

There is no memory limit imposed by Python. However, you will get a MemoryError if you run out of RAM. You say you have 20301 elements in the list. This seems too small to cause a memory error for simple data types (e.g. int), but if each element itself is an object that takes up a lot of memory, you may well be running out of memory.

The IndexError however is probably caused because your ListTemp has got only 19767 elements (indexed 0 to 19766), and you are trying to access past the last element.

It is hard to say what you can do to avoid hitting the limit without knowing exactly what it is that you are trying to do. Using numpy might help. It looks like you are storing a huge amount of data. It may be that you don't need to store all of it at every stage. But it is impossible to say without knowing.

This visualization can help us to find out difference between concept of element and tag (each indent means contain):

- element

        - content:

            - text 

            - other elements 

            - or empty

        - and its markup

            - tags (start or end tag)

                - element name

                - angle brackets < >

                - or attributes (just for start tag)

                - or slash / 

"If you're going to use apostrophes, 
       ^

For that simple reason, I always use double quotes on the outside. Always

Speaking of fluff, what good is streamlining your string literals with ' if you're going to have to use escape characters to represent apostrophes? Does it offend coders to read novels? I can't imagine how painful high school English class was for you!

As mentioned in the accepted answer

import os
dir = os.path.dirname(__file__)
filename = os.path.join(dir, '/relative/path/to/file/you/want')

I just want to add that

the latter string can't begin with the backslash , infact no string should include a backslash

It should be something like

import os
dir = os.path.dirname(__file__)
filename = os.path.join(dir, 'relative','path','to','file','you','want')

The accepted answer can be misleading in some cases , please refer to this link for details

The quick and dirty way I use to export mysql output to a file is

$ mysql <database_name> --tee=<file_path>

and then use the exported output (which you can find in <file_path>) wherever I want.

Note that this is the only way you have in order to avoid databases running using the secure-file-priv option, which prevents the usage of INTO OUTFILE suggested in the previous answers:

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

How about using direct axios API?

axios({
  method: 'post',
  url: baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
  headers: {}, 
  data: {
    foo: 'bar', // This is the body part
  }
});

Given the, most than probable similarities in performance, use whatever feel more correct and readable to the piece of code you're using.

I feel an operation that describes an addition, being the presence of the key already a really rare exception is best represented with the add. Semantically it makes more sense.

The dict[key] = value represents better a substitution. If I see that code I half expect the key to already be in the dictionary anyway.

There are a few problems here.

First of all, there is no such thing as <button type="cancel">, so it is treated as just a <button>. This means that your form will be submitted, instead of the button taking you elsewhere.

Second, javascript: is only needed in href or action attributes, where a URL is expected, to designate JavaScript code. Inside onclick, where JavaScript is already expected, it merely acts as a label and serves no real purpose.

Finally, it's just generally better design to have a cancel link rather than a cancel button. So you can just do this:

<a href="http://stackoverflow.com/">Cancel</a>

With CSS you can even make it look the same as a button, but with this HTML there is absolutely no confusion as to what it is supposed to do.

A bit late to the party, but I had to solve this for myself recently, though slightly different, it might still help someone with similar circumstances to my own.

I'm using xampp on a laptop to run a purely local website app on windows. (A very specific environment I know). In this instance, I use a html link to a php file and run:

shell_exec('cd C:\path\to\file');
shell_exec('start .');

This opens a local Windows explorer window.

Josh is correct but he left out one variation:

ALTER ROLE <role_name> IN DATABASE <db_name> SET search_path TO schema1,schema2;

Set the search path for the user, in one particular database.

You could do something like this:

htmlComponent.ts

htmlVariable: string = "<b>Some html.</b>"; //this is html in TypeScript code that you need to display

htmlComponent.html

<div [innerHtml]="htmlVariable"></div> //this is how you display html code from TypeScript in your html

nelek's answer is the best one posted so far, but it relies on setting the css value: white-space: pre, which might be undesirable.

I'd like to offer a different solution, which tries to tackle the real question that should've been asked here:

"How to insert untrusted text into a DOM element?"

If you trust the text, why not just use innerHTML?

domElement.innerHTML = trustedText.replace(/\r/g, '').replace(/\n/g, '<br>');

should be sufficient for all the reasonable cases.

If you decided you should use .textContent instead of .innerHTML, it means you don't trust the text that you're about to insert, right? This is a reasonable concern.

For example, you have a form where the user can create a post, and after posting it, the post text is stored in your database, and later on appended to pages whenever other users visit the relevant page.

If you use innerHTML here, you get a security breach. i.e., a user can post something like

[script]alert(1);[/script]

(try to imagine that [] are <>, apparently stack overflow is appending text in unsafe ways!)

which won't trigger an alert if you use innerHTML, but it should give you an idea why using innerHTML can have issues. a smarter user would post

[img src="invalid_src" onerror="alert(1)"]

which would trigger an alert for every other user that visits the page. Now we have a problem. An even smarter user would put display: none on that img style, and make it post the current user's cookies to a cross domain site. Congratulations, all your user login details are now exposed on the internet.

So, the important thing to understand is, using innerHTML isn't wrong, it's perfect if you're just using it to build templates using only your own trusted developer code. The real question should've been "how do I append untrusted user text that has newlines to my HTML document".

This raises a question: which strategy do we use for newlines? do we use [br] elements? [p]s or [div]s?

Here is a short function that solves the problem:

function insertUntrustedText(domElement, untrustedText, newlineStrategy) {
    domElement.innerHTML = '';
    var lines = untrustedText.replace(/\r/g, '').split('\n');
    var linesLength = lines.length;
    if(newlineStrategy === 'br') {
        for(var i = 0; i < linesLength; i++) {
            domElement.appendChild(document.createTextNode(lines[i]));
            domElement.appendChild(document.createElement('br'));
        }
    }
    else {
        for(var i = 0; i < linesLength; i++) {
            var lineElement = document.createElement(newlineStrategy);
            lineElement.textContent = lines[i];
            domElement.appendChild(lineElement);
        }
    }
}

You can basically throw this somewhere in your common_functions.js file and then just fire and forget whenever you need to append any user/api/etc -> untrusted text (i.e. not-written-by-your-own-developer-team) to your html pages.

usage example:

insertUntrustedText(document.querySelector('.myTextParent'), 'line1\nline2\r\nline3', 'br');

the parameter newlineStrategy accepts only valid dom element tags, so if you want [br] newlines, pass 'br', if you want each line in a [p] element, pass 'p', etc.

The simpler solution will be to user pyftpd library. This library allows you to spin Python FTP server in one line. It doesn’t come installed by default though, but we can install it using simple apt command

apt-get install python-pyftpdlib

now from the directory you want to serve just run the pythod module

python -m pyftpdlib -p 21 

$year = date("Y");   
$month = date("m");   
$filename = "../".$year;   
$filename2 = "../".$year."/".$month;

if(file_exists($filename)){
    if(file_exists($filename2)==false){
        mkdir($filename2,0777);
    }
}else{
    mkdir($filename,0777);
}

let cooridinate = CLLocationCoordinate2D(latitude: 12.9767415 , longitude: 77.6903967)
let  spanDegree = MKCoordinateSpan(latitudeDelta: 0.2,longitudeDelta: 0.2)
let region = MKCoordinateRegion(center: cooridinate , span: spanDegree)
mapView.setRegion(region, animated: true)

This usually has to do with a selector not being used properly. Check and make sure that you are using the jQuery selectors like intended. For example I had this problem when creating a click method:

$("[editButton]").click(function () {
    this.css("color", "red");
});

Because I was not using the correct selector method $(this) for jQuery it gave me the same error.

So simply enough, check your selectors!

You can control client cache with HTTP headers. This works in any web framework.

You can set the directives these headers to have fine grained control over how and when to enable|disable cache:

• Cache-Control
• Surrogate-Control
• Expires
• ETag (very good one)
• Pragma (if you want to support old browsers)

Good caching is good, but very complex, in all computer systems. Take a look at https://helmetjs.github.io/docs/nocache/#the-headers for more information.

jQuery's empty() function does just that:

$('#masterdiv').empty();

clears the master div.

$('#masterdiv div').empty();

clears all the child divs, but leaves the master intact.

Here I have an example of Bootstrap 3 popover showing an image with the tittle above it when the mouse hovers over some text. I've put in some inline styling that you may want to take out or change.....

I was also facing same issue. I had Jdk1.7.0.79. Then I updated it with Jdk8.0.120. Then the problem solved. After successful completion of upgraded jdk. Go to project->clean. It will rebuild the project and all red alert will be eliminated.

In my experience, /var/www/ directory directive prevents subfolder virtualhost directives. So if you had tried all suggestions and still not working and you are using virtualhosts try this ;

1 - Be sure that you have AllowOverride All directive in /etc/apache2/sites-available/example.com.conf

2 - Check /var/www/ Directory directives in /etc/apache2/apache2.conf (possibly at line 164), which looks like ;

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

If there is an AllowOverride None directive change it to AllowOverride All or just escape line

In addition: if you show links in listview in fragment, do not create it like this

adapter = new ListAdapter(getActivity().getApplicationContext(),mStrings);

instead call

adapter = new ListAdapter(getActivity(),mStrings);

adapter works fine in both cases, but links work only in last one.

you can:

use integer;

it is explained by Michael Ratanapintha or else use manually:

$a=3.7;
$b=2.1;

$c=int(int($a)/int($b));

notice, 'int' is not casting. this is function for converting number to integer form. this is because Perl 5 does not have separate integer division. exception is when you 'use integer'. Then you will lose real division.

Use pd.to_numeric with errors='coerce'

# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

0    1
1    2
2    3
3    4
4    .
dtype: object

pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
dtype: float64

If you need the NaNs filled in, use Series.fillna.

pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')

0    1
1    2
2    3
3    4
4    0
dtype: float64

Note, downcast='infer' will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.

From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use

pd.__version__
# '0.24.1'

pd.to_numeric(s, errors='coerce').astype('Int32')

0      1
1      2
2      3
3      4
4    NaN
dtype: Int32

There are other options to choose from as well, read the docs for more.

Extension for DataFrames

If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply.

# Setup.
np.random.seed(0)
df = pd.DataFrame({
    'A' : np.random.choice(10, 5), 
    'C' : np.random.choice(10, 5), 
    'B' : ['1', '###', '...', 50, '234'], 
    'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df

   A    B  C    D
0  5    1  9   23
1  0  ###  3    1
2  3  ...  5  ...
3  3   50  2  268
4  7  234  4   $$

df.dtypes

A     int64
B    object
C     int64
D    object
dtype: object

df2 = df.apply(pd.to_numeric, errors='coerce')
df2

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

df2.dtypes

A      int64
B    float64
C      int64
D    float64
dtype: object

You can also do this with DataFrame.transform; although my tests indicate this is marginally slower:

df.transform(pd.to_numeric, errors='coerce')

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN

If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric on the non-numeric columns only.

df.dtypes.eq(object)

A    False
B     True
C    False
D     True
dtype: bool

cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')

df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
#     df[c] = pd.to_numeric(df[c], errors='coerce')

df

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

Applying pd.to_numeric along the columns (i.e., axis=0, the default) should be slightly faster for long DataFrames.

from msdn: public void Save (string filename); which is quite surprising to me because we dont just have to pass in the filename, we have to pass the filename along with the path for example: MyDirectory/MyImage.jpeg, here MyImage.jpeg does not actually exist yet, but our file will be saved with this name.

Another important point here is that if you are using Save() in a web application then use Server.MapPath() along with it which basically just returns the physical path for the virtual path which is passed in. Something like: image.Save(Server.MapPath("~/images/im111.jpeg"));

In case anyone wants an alternative method...

If it is the last subdirectory in the path, you can use this one-liner:

cd "c:\directory\subdirectory\filename.exe\..\.." && dir /ad /b /s

This would return the following:

c:\directory\subdirectory

The .... drops back to the previous directory. /ad shows only directories /b is a bare format listing /s includes all subdirectories. This is used to get the full path of the directory to print.

when a derived class object is assigned to a base class object, additional attributes of a derived class object are sliced off (discard) form the base class object.

class Base { 
int x;
 };

class Derived : public Base { 
 int z; 
 };

 int main() 
{
Derived d;
Base b = d; // Object Slicing,  z of d is sliced off
}

I had the same problem. I installed Eclipse 3.7 into a new folder, and created a new workspace. I launch Eclipse with a -data argument to reference the new workspace.

When I attempt to connect to the marketplace to get the SVN and Maven plugins, I get the same issues described in OP.

After a few more tries, I cleared the proxy settings for SOCKS protocol, and I was able to connect to the marketplace.

So the solution for me was to configure the manual settings for HTTP and HTTPS proxy, clear the settings for SOCKS, and restart Eclipse.

You can not change the length of an array, but you can change the values the index holds by copying new values and store them to a existing index number. 1=mike , 2=jeff // 10 = george 11 goes to 1 overwriting mike .

Object[] array = new Object[10];
int count = -1;

public void myFunction(String string) {
    count++;
    if(count == array.length) { 
        count = 0;  // overwrite first
    }
    array[count] = string;    
}

This is how I did it:

let fs = require('fs');
let path = require('path');

Then:

let filePath = // Your file path

let fileList = []
    var walkSync = function(filePath, filelist)
    {
        let files = fs.readdirSync(filePath);
        filelist = filelist || [];
        files.forEach(function(file)
        {
            if (fs.statSync(path.join(filePath, file)).isDirectory())
            {
                filelist = walkSync(path.join(filePath, file), filelist);
            }
            else
            {
                filelist.push(path.join(filePath, file));
            }
        });

        // Ignore hidden files
        filelist = filelist.filter(item => !(/(^|\/)\.[^\/\.]/g).test(item));

        return filelist;
    };

Then call the method:

This.walkSync(filePath, fileList)

var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; ++i) {
  // ...
}

Please make sure your python or python3 can see xlrd installation. I had a situation where python3.5 and python3.7 were installed in two different locations. While xlrd was installed with python3.5, I was using python3 (from python3.7 dir) to run my script and got the same error reported above. When I used the correct python (viz. python3.5 dir) to run my script, I was able to read the excel spread sheet without a problem.

My solution is using lookup and generate password automatically.

---
- hosts: 'all'
  remote_user: root
  gather_facts: no
  vars:
    deploy_user: deploy
    deploy_password: "{{ lookup('password', '/tmp/password chars=ascii_letters') }}"

  tasks:
    - name: Create deploy user
      user:
        name: "{{ deploy_user }}"
        password: "{{ deploy_password | password_hash('sha512') }}"

To expand on the @PostConstruct suggestion in other answers, this really is the best solution, in my opinion.

• It keeps your code decoupled from the Spring API (@PostConstruct is in javax.*)
• It explicitly annotates your init method as something that needs to be called to initialize the bean
• You don't need to remember to add the init-method attribute to your spring bean definition, spring will automatically call the method (assuming you register the annotation-config option somewhere else in the context, anyway).

Scala lists are immutable by default. You cannot "add" an element, but you can form a new list by appending the new element in front. Since it is a new list, you need to reassign the reference (so you can't use a val).

var dm  = List[String]()
var dk = List[Map[String,AnyRef]]()

.....

dm = "text" :: dm
dk = Map(1 -> "ok") :: dk

The operator :: creates the new list. You can also use the shorter syntax:

dm ::= "text" 
dk ::= Map(1 -> "ok")

NB: In scala don't use the type Object but Any, AnyRef or AnyVal.

I'd probably use all.equal and which to get the information you want. It's not recommended to use all.equal in an if...else block for some reason, so we wrap it in isTRUE(). See ?all.equal for more:

foo <- function(A,B){
  if (!isTRUE(all.equal(A,B))){
    mismatches <- paste(which(A != B), collapse = ",")
    stop("error the A and B does not match at the following columns: ", mismatches )
  } else {
    message("Yahtzee!")
  }
}

And in use:

> foo(A,A)
Yahtzee!
> foo(A,B)
Yahtzee!
> foo(A,C)
Error in foo(A, C) : 
  error the A and B does not match at the following columns: 2,4

cd /tmp
find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n'

A short explanation:

• find finds files (quite obviously)

• . is the current directory, which after the cd is /tmp (IMHO this is more flexible than having /tmp directly in the find command. You have only one place, the cd, to change, if you want more actions to take place in this folder)

• -maxdepth 1 and -mindepth 1 make sure that find only looks in the current directory and doesn't include . itself in the result

• -type d looks only for directories

• -printf '%f\n prints only the found folder's name (plus a newline) for each hit.

Et voilà!

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

You could use "Test Mail Server Tool" to test email sending on your machine or localhost. Google and Download "Test Mail Server Tool" and set it up.

Then in your settings.py:

EMAIL_BACKEND= 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25

From shell:

from django.core.mail import send_mail
send_mail('subject','message','sender email',['receipient email'],    fail_silently=False)

If you need to pass a variable along with the 'this' keyword, the below code works:

var status = 'Active';
var anchorHTML = '<a href ="#" onClick = "DisplayActiveStatus(this,\'' + status + '\')">' + data+ '</a>';

They should be pretty much the same. The difference isn't going to matter. I would go with sprintf since it requires less code.

For a repository setting solution, that can be redistributed to all developers, check out the text attribute in the .gitattributes file. This way, developers dont have to manually set their own line endings on the repository, and because different repositories can have different line ending styles, global core.autocrlf is not the best, at least in my opinion.

For example unsetting this attribute on a given path [. - text] will force git not to touch line endings when checking in and checking out. In my opinion, this is the best behavior, as most modern text editors can handle both type of line endings. Also, if you as a developer still want to do line ending conversion when checking in, you can still set the path to match certain files or set the eol attribute (in .gitattributes) on your repository.

Also check out this related post, which describes .gitattributes file and text attribute in more detail: What's the best CRLF (carriage return, line feed) handling strategy with Git?

You code is correct. replace items with .items as below

<script>
  var n = $(".items").css("left");
  if(n == -900){
    $(".items span").fadeOut("slow");
  }
</script>

I had same issue along with https://stackoverflow.com/a/57245058/8968137 and both solved after fixing the google-services.json

white-space: nowrap is the correct solution but it will prevent any break in a line. If you only want to prevent line breaks between two elements it gets a bit more complicated:

<p>
    <span class="text">Some text</span>
    <span class="icon"></span>
</p>

To prevent breaks between the spans but to allow breaks between "Some" and "text" can be done by:

p {
    white-space: nowrap;
}

.text {
    white-space: normal;
}

That's good enough for Firefox. In Chrome you additionally need to replace the whitespace between the spans with an  . (Removing the whitespace doesn't work.)

Recently I found that mistake happened not only in case when you forgot to import FormsModule in your module. In my case problem was in this code:

<input type="text" class="form-control" id="firstName"
                   formControlName="firstName" placeholder="Enter First Name"
                   value={{user.firstName}} [(ngModel)]="user.firstName">

I fix it with change formControlName -> name

<input type="text" class="form-control" id="firstName"
                   name="firstName" placeholder="Enter First Name"
                   value={{user.firstName}} [(ngModel)]="user.firstName">

This is an additional way to find out the number of CPU cores (and a lot of other information), but this code requires an additional dependence:

Native Operating System and Hardware Information https://github.com/oshi/oshi

SystemInfo systemInfo = new SystemInfo();
HardwareAbstractionLayer hardwareAbstractionLayer = systemInfo.getHardware();
CentralProcessor centralProcessor = hardwareAbstractionLayer.getProcessor();

Get the number of logical CPUs available for processing:

centralProcessor.getLogicalProcessorCount();

Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:

All non-alphanumeric characters other than \, -, ^ (at the start) and the terminating ] are non-special in character classes, but it does no harm if they are escaped.

For more info about Java regular expressions, see the docs.

Yes, you can do this in PHP e.g. in

Silex or Symfony3

using subrequest

$postParams = array(
    'email' => $request->get('email'),
    'agree_terms' => $request->get('agree_terms'),
);

$subRequest = Request::create('/register', 'POST', $postParams);
return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);

Change your ref into: ref='title' and delete name='title' Then delete var title = this.title and write:

console.log(this.refs.title.value)

Also you should add .bind(this) to this.onSubmit

(It worked in my case which was quite similar, but instead of onClick I had onSubmit={...} and it was put in form ( <form onSubmit={...} ></form>))

I had a similar incident with stopping a log shipping secondary server. After the command to remove the server from log shipping and stopped the log shipping from primary server the database on secondary server got stuck in restoring status after the command

RESTORE DATABASE <database name> WITH RECOVERY

The database messages:

RESTORE DATABASE successfully processed 0 pages in 18.530 seconds (0.000 MB/sec).

The database was usable again after those 18 seconds.

User Animated Scrolling

Here's an example of how to programmatically scroll a <div> horizontally, without JQuery. To scroll vertically, you would replace JavaScript's writes to scrollLeft with scrollTop, instead.

In addition, here are functions for scrolling a <div> fully to the left and right. The only thing we change here is we make a check to see if the full extension of the scroll has been utilised before making a recursive call to scroll again.

Set the aspectRatio property of the chart to 0 did the trick for me...

This can be achieved by using grep to see if the variable in question matches an extended regular expression.

Test integer 1120:

yournumber=1120
if echo "$yournumber" | grep -qE '^[0-9]+$'; then
    echo "Valid number."
else
    echo "Error: not a number."
fi

Output: Valid number.

Test non-integer 1120a:

yournumber=1120a
if echo "$yournumber" | grep -qE '^[0-9]+$'; then
    echo "Valid number."
else
    echo "Error: not a number."
fi

Output: Error: not a number.

Explanation

• The grep, the -E switch allows us to use extended regular expression '^[0-9]+$'. This regular expression means the variable should only [] contain the numbers 0-9 zero through nine from the ^ beginning to the $ end of the variable and should have at least + one character.
• The grep, the -q quiet switch turns off any output whether or not it finds anything.
• if checks the exit status of grep. Exit status 0 means success and anything greater means an error. The grep command has an exit status of 0 if it finds a match and 1 when it doesn't;

So putting it all together, in the if test, we echo the variable $yournumber and | pipe it to grep which with the -q switch silently matches the -E extended regular expression '^[0-9]+$' expression. The exit status of grep will be 0 if grep successfully found a match and 1 if it didn't. If succeeded to match, we echo "Valid number.". If it failed to match, we echo "Error: not a number.".

For Floats or Doubles

We can just change the regular expression from '^[0-9]+$' to '^[0-9]*\.?[0-9]+$' for floats or doubles.

Test float 1120.01:

yournumber=1120.01
if echo "$yournumber" | grep -qE '^[0-9]*\.?[0-9]+$'; then
    echo "Valid number."
else
    echo "Error: not a number."
fi

Output: Valid number.

Test float 11.20.01:

yournumber=11.20.01
if echo "$yournumber" | grep -qE '^[0-9]*\.?[0-9]+$'; then
    echo "Valid number."
else
    echo "Error: not a number."
fi

Output: Error: not a number.

For Negatives

To allow negative integers, just change the regular expression from '^[0-9]+$' to '^\-?[0-9]+$'.

To allow negative floats or doubles, just change the regular expression from '^[0-9]*\.?[0-9]+$' to '^\-?[0-9]*\.?[0-9]+$'.

(I was going to leave this as a comment on @jldupont's answer, but I don't have enough reputation.)

I've seen answers like @jldupont's answer in other places as well. FWIW, I think it's important to note that this:

except Exception as e:
    print(e)

will print the error output to sys.stdout by default. A more appropriate approach to error handling in general would be:

except Exception as e:
    print(e, file=sys.stderr)

(Note that you have to import sys for this to work.) This way, the error is printed to STDERR instead of STDOUT, which allows for the proper output parsing/redirection/etc. I understand that the question was strictly about 'printing an error', but it seems important to point out the best practice here rather than leave out this detail that could lead to non-standard code for anyone who doesn't eventually learn better.

I haven't used the traceback module as in Cat Plus Plus's answer, and maybe that's the best way, but I thought I'd throw this out there.

It's pretty easy to write one:

Object.map = function(o, f, ctx) {
    ctx = ctx || this;
    var result = {};
    Object.keys(o).forEach(function(k) {
        result[k] = f.call(ctx, o[k], k, o); 
    });
    return result;
}

with example code:

> o = { a: 1, b: 2, c: 3 };
> r = Object.map(o, function(v, k, o) {
     return v * v;
  });
> r
{ a : 1, b: 4, c: 9 }

NB: this version also allows you to (optionally) set the this context for the callback, just like the Array method.

EDIT - changed to remove use of Object.prototype, to ensure that it doesn't clash with any existing property named map on the object.

I may be quite late to the party, but we can create custom foldr using simple lambda calculus and curried function. Here is my implementation of foldr in python.

Maybe you are out of inodes. Try df -i

                     2591792  136322 2455470    6% /home
/dev/sdb1            1887488 1887488       0  100% /data

Disk used 6% but inode table full.

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

I had something similar when passing a script to a function with invoke-command. I ran the command in single quotes instead of double quotes, because it then becomes a string literal. 'Set-Mailbox $sourceUser -LitigationHoldEnabled $false -ElcProcessingDisabled $true';

You don't need to calculate anything, and probably shouldn't:

<!DOCTYPE html>
<head>
<style type="text/css">
    body {background: blue; height:100%;}
    header {background: red; height: 20px; width:100%}
    h1 {font-size:1.2em; margin:0; padding:0; 
        height: 30px; font-weight: bold; background:yellow}
    .theCalcDiv {background-color:green; padding-bottom: 100%}
</style>
</head>
<body>
<header>Some nav stuff here</header>
<h1>This is the heading</h1>
<div class="theCalcDiv">This blocks needs to have a CSS calc() height of 100% - the height of the other elements.
</div>

I stuck it all together for brevity.

The old syntax, with just listing the tables, and using the WHERE clause to specify the join criteria, is being deprecated in most modern databases.

It's not just for show, the old syntax has the possibility of being ambiguous when you use both INNER and OUTER joins in the same query.

Let me give you an example.

Let's suppose you have 3 tables in your system:

Company
Department
Employee

Each table contain numerous rows, linked together. You got multiple companies, and each company can have multiple departments, and each department can have multiple employees.

Ok, so now you want to do the following:

List all the companies, and include all their departments, and all their employees. Note that some companies don't have any departments yet, but make sure you include them as well. Make sure you only retrieve departments that have employees, but always list all companies.

So you do this:

SELECT * -- for simplicity
FROM Company, Department, Employee
WHERE Company.ID *= Department.CompanyID
  AND Department.ID = Employee.DepartmentID

Note that the last one there is an inner join, in order to fulfill the criteria that you only want departments with people.

Ok, so what happens now. Well, the problem is, it depends on the database engine, the query optimizer, indexes, and table statistics. Let me explain.

If the query optimizer determines that the way to do this is to first take a company, then find the departments, and then do an inner join with employees, you're not going to get any companies that don't have departments.

The reason for this is that the WHERE clause determines which rows end up in the final result, not individual parts of the rows.

And in this case, due to the left join, the Department.ID column will be NULL, and thus when it comes to the INNER JOIN to Employee, there's no way to fulfill that constraint for the Employee row, and so it won't appear.

On the other hand, if the query optimizer decides to tackle the department-employee join first, and then do a left join with the companies, you will see them.

So the old syntax is ambiguous. There's no way to specify what you want, without dealing with query hints, and some databases have no way at all.

Enter the new syntax, with this you can choose.

For instance, if you want all companies, as the problem description stated, this is what you would write:

SELECT *
FROM Company
     LEFT JOIN (
         Department INNER JOIN Employee ON Department.ID = Employee.DepartmentID
     ) ON Company.ID = Department.CompanyID

Here you specify that you want the department-employee join to be done as one join, and then left join the results of that with the companies.

Additionally, let's say you only want departments that contains the letter X in their name. Again, with old style joins, you risk losing the company as well, if it doesn't have any departments with an X in its name, but with the new syntax, you can do this:

SELECT *
FROM Company
     LEFT JOIN (
         Department INNER JOIN Employee ON Department.ID = Employee.DepartmentID
     ) ON Company.ID = Department.CompanyID AND Department.Name LIKE '%X%'

This extra clause is used for the joining, but is not a filter for the entire row. So the row might appear with company information, but might have NULLs in all the department and employee columns for that row, because there is no department with an X in its name for that company. This is hard with the old syntax.

This is why, amongst other vendors, Microsoft has deprecated the old outer join syntax, but not the old inner join syntax, since SQL Server 2005 and upwards. The only way to talk to a database running on Microsoft SQL Server 2005 or 2008, using the old style outer join syntax, is to set that database in 8.0 compatibility mode (aka SQL Server 2000).

Additionally, the old way, by throwing a bunch of tables at the query optimizer, with a bunch of WHERE clauses, was akin to saying "here you are, do the best you can". With the new syntax, the query optimizer has less work to do in order to figure out what parts goes together.

So there you have it.

LEFT and INNER JOIN is the wave of the future.

Some people hilighted some goods points (and some of my thoughts):

• It could looklikes insane to unable random accesser (indexer) but to me it appears fine. You only have to think that there is many methods on multi-threaded collections that could fail like Indexer and Delete. You could also define failure (fallback) action for write accessor like "fail" or simply "add at the end".
• It is not because it is a multithreaded collection that it will always be used in a multithreaded context. Or it could also be used by only one writer and one reader.
• Another way to be able to use indexer in a safe manner could be to wrap actions into a lock of the collection using its root (if made public).
• For many people, making a rootLock visible goes agaist "Good practice". I'm not 100% sure about this point because if it is hidden you remove a lot of flexibility to the user. We always have to remember that programming multithread is not for anybody. We can't prevent every kind of wrong usage.
• Microsoft will have to do some work and define some new standard to introduce proper usage of Multithreaded collection. First the IEnumerator should not have a moveNext but should have a GetNext that return true or false and get an out paramter of type T (this way the iteration would not be blocking anymore). Also, Microsoft already use "using" internally in the foreach but sometimes use the IEnumerator directly without wrapping it with "using" (a bug in collection view and probably at more places) - Wrapping usage of IEnumerator is a recommended pratice by Microsoft. This bug remove good potential for safe iterator... Iterator that lock collection in constructor and unlock on its Dispose method - for a blocking foreach method.

That is not an answer. This is only comments that do not really fit to a specific place.

... My conclusion, Microsoft has to make some deep changes to the "foreach" to make MultiThreaded collection easier to use. Also it has to follow there own rules of IEnumerator usage. Until that, we can write a MultiThreadList easily that would use a blocking iterator but that will not follow "IList". Instead, you will have to define own "IListPersonnal" interface that could fail on "insert", "remove" and random accessor (indexer) without exception. But who will want to use it if it is not standard ?

I was just wondering why we can't call await from within a constructor directly.

I believe the short answer is simply: Because the .Net team has not programmed this feature.

I believe with the right syntax this could be implemented and shouldn't be too confusing or error prone. I think Stephen Cleary's blog post and several other answers here have implicitly pointed out that there is no fundamental reason against it, and more than that - solved that lack with workarounds. The existence of these relatively simple workarounds is probably one of the reasons why this feature has not (yet) been implemented.

well since we use functions to handle an onchange event, we can do it like this:

class Form extends Component {
 constructor(props) {
  super(props);
  this.handlePasswordChange = this.handlePasswordChange.bind(this);
  this.state = { password: '' }
 }

 aForceChange() {
  // something happened and a passwordChange
  // needs to be triggered!!

  // simple, just call the onChange handler
  this.handlePasswordChange('my password');
 }

 handlePasswordChange(value) {
 // do something
 }

 render() {
  return (
   <input type="text" value={this.state.password} onChange={changeEvent => this.handlePasswordChange(changeEvent.target.value)} />
  );
 }
}

If you specify the option 'openany' in the \documentclass declaration each chapter in the book (I'm guessing you're using the book class as chapters open on the next page in reports and articles don't have chapters) will open on a new page, not necessarily the next odd-numbered page.

Of course, that's not quite what you want. I think you want to set openany for chapters in the appendix. 'fraid I don't know how to do that, I suspect that you need to roll up your sleeves and wrestle with TeX itself

In my cases, I solved the problem when using the labs() instead of abs().

In Swift 4.1 and Xcode 9.4.1

In iOS 11 this single line is enough:

detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]//Set your view here

See the complete code:

//In viewDidLoad
if #available(iOS 11.0, *) {
        detailsSubView.clipsToBounds = false
        detailsSubView.layer.cornerRadius = 10
        detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
} else {
      //For lower versions
}

But for lower versions

let rectShape = CAShapeLayer()
    rectShape.bounds = detailsSubView.frame
    rectShape.position = detailsSubView.center
    rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    detailsSubView.layer.mask = rectShape

Complete code is.

if #available(iOS 11.0, *) {
    detailsSubView.clipsToBounds = false
    detailsSubView.layer.cornerRadius = 10
    detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
} else {
    let rectShape = CAShapeLayer()
    rectShape.bounds = detailsSubView.frame
    rectShape.position = detailsSubView.center
    rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    detailsSubView.layer.mask = rectShape
}

If you are using AutoResizing in storyboard write this code in viewDidLayoutSubviews().

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if #available(iOS 11.0, *) {
        detailsSubView.clipsToBounds = false
        detailsSubView.layer.cornerRadius = 10
        detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
    } else {
        let rectShape = CAShapeLayer()
        rectShape.bounds = detailsSubView.frame
        rectShape.position = detailsSubView.center
        rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
        detailsSubView.layer.mask = rectShape
    }
}

Executive summary: it's 64 bits, or larger.

unsigned long long is the same as unsigned long long int. Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits. There was no long long in C89, but apparently even MSVC supports it, so it's quite portable.

In the current C++ standard (issued in 2003), there is no long long, though many compilers support it as an extension. The upcoming C++0x standard will support it and its size will be the same as in C, so at least 64 bits.

You can get the exact size, in bytes (8 bits on typical platforms) with the expression sizeof(unsigned long long). If you want exactly 64 bits, use uint64_t, which is defined in the header <stdint.h> along with a bunch of related types (available in C99, C++11 and some current C++ compilers).

setTimeout(callback,t) is used to run callback after at least t millisecond. The actual delay depends on many external factors like OS timer granularity and system load.

So, there is a possibility that it will be called slightly after the set time, but will never be called before.

A timer can't span more than 24.8 days.

Another solution without you having to manually mess around with the Unicode characters can be found in Making Font Awesome awesome - Using icons without i-tags (disclaimer: I wrote this article).

In a nutshell, you can create a new class like this:

.icon::before {
    display: inline-block;
    margin-right: .5em;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    transform: translate(0, 0);
}

And then use it with any icon, for example:

<a class="icon fa-car" href="#">This is a link</a>

I suggest getting comfortable with Git before trying to use git-svn constantly, i.e. keeping SVN as the centralized repo and using Git locally.

However, for a simple migration with all the history, here are the few simple steps:

Initialize the local repo:

mkdir project
cd project
git svn init http://svn.url

Mark how far back you want to start importing revisions:

git svn fetch -r42

(or just "git svn fetch" for all revs)

Actually fetch everything since then:

git svn rebase

You can check the result of the import with Gitk. I'm not sure if this works on Windows, it works on OSX and Linux:

gitk

When you've got your SVN repo cloned locally, you may want to push it to a centralized Git repo for easier collaboration.

First create your empty remote repo (maybe on GitHub?):

git remote add origin [email protected]:user/project-name.git

Then, optionally sync your main branch so the pull operation will automatically merge the remote master with your local master, when both contain new stuff:

git config branch.master.remote origin
git config branch.master.merge refs/heads/master

After that, you may be interested in trying out my very own git_remote_branch tool, which helps dealing with remote branches:

First explanatory post: "Git remote branches"

Follow-up for the most recent version: "Time to git collaborating with git_remote_branch"

C++17 (N4659) includes a proposal Refining Expression Evaluation Order for Idiomatic C++ which defines a stricter order of expression evaluation.

In particular, the following sentence

8.18 Assignment and compound assignment operators:
....

In all cases, the assignment is sequenced after the value computation of the right and left operands, and before the value computation of the assignment expression. The right operand is sequenced before the left operand.

together with the following clarification

An expression X is said to be sequenced before an expression Y if every value computation and every side effect associated with the expression X is sequenced before every value computation and every side effect associated with the expression Y.

make several cases of previously undefined behavior valid, including the one in question:

a[++i] = i;

However several other similar cases still lead to undefined behavior.

In N4140:

i = i++ + 1; // the behavior is undefined

But in N4659

i = i++ + 1; // the value of i is incremented
i = i++ + i; // the behavior is undefined

Of course, using a C++17 compliant compiler does not necessarily mean that one should start writing such expressions.

Simple answer NO.

However you can achieve something similar by running the following version using bind variables:

SELECT * FROM Employees WHERE EmployeeID = :EmpIDVar 

Once you run the query above in SQL Developer you will be prompted to enter value for the bind variable EmployeeID.

Missing images will either just display nothing, or display a [ ? ] style box when their source cannot be found. Instead you may want to replace that with a "missing image" graphic that you are sure exists so there is better visual feedback that something is wrong. Or, you might want to hide it entirely. This is possible, because images that a browser can't find fire off an "error" JavaScript event we can watch for.

    //Replace source
    $('img').error(function(){
            $(this).attr('src', 'missing.png');
    });

   //Or, hide them
   $("img").error(function(){
           $(this).hide();
   });

Additionally, you may wish to trigger some kind of Ajax action to send an email to a site admin when this occurs.

When i need to copy data from filtered table i use range.SpecialCells(xlCellTypeVisible).copy. Where the range is range of all data (without a filter).

Example:

Sub copy()
     'source worksheet
     dim ws as Worksheet
     set ws = Application.Worksheets("Data")' set you source worksheet here
     dim data_end_row_number as Integer
     data_end_row_number = ws.Range("B3").End(XlDown).Row.Number
    'enable filter
    ws.Range("B2:F2").AutoFilter Field:=2, Criteria1:="hockey", VisibleDropDown:=True
    ws.Range("B3:F" & data_end_row_number).SpecialCells(xlCellTypeVisible).Copy
    Application.Worksheets("Hoky").Range("B3").Paste
    'You have to add headers to Hoky worksheet
end sub

One of the most beautiful ways in my opinion (since it is now commonly available) is using behaviours.

It requires:

• nuget dependency: Microsoft.Xaml.Behaviors.Wpf
• if you already have behaviours built in you might have to follow this guide on Microsofts blog.

xaml code:

xmlns:Interactions="http://schemas.microsoft.com/xaml/behaviors"

AND

<Hyperlink NavigateUri="{Binding Path=Link}">
    <Interactions:Interaction.Behaviors>
        <behaviours:HyperlinkOpenBehaviour ConfirmNavigation="True"/>
    </Interactions:Interaction.Behaviors>
    <Hyperlink.Inlines>
        <Run Text="{Binding Path=Link}"/>
    </Hyperlink.Inlines>
</Hyperlink>

behaviour code:

using System.Windows;
using System.Windows.Documents;
using System.Windows.Navigation;
using Microsoft.Xaml.Behaviors;

namespace YourNameSpace
{
    public class HyperlinkOpenBehaviour : Behavior<Hyperlink>
    {
        public static readonly DependencyProperty ConfirmNavigationProperty = DependencyProperty.Register(
            nameof(ConfirmNavigation), typeof(bool), typeof(HyperlinkOpenBehaviour), new PropertyMetadata(default(bool)));

        public bool ConfirmNavigation
        {
            get { return (bool) GetValue(ConfirmNavigationProperty); }
            set { SetValue(ConfirmNavigationProperty, value); }
        }

        /// <inheritdoc />
        protected override void OnAttached()
        {
            this.AssociatedObject.RequestNavigate += NavigationRequested;
            this.AssociatedObject.Unloaded += AssociatedObjectOnUnloaded;
            base.OnAttached();
        }

        private void AssociatedObjectOnUnloaded(object sender, RoutedEventArgs e)
        {
            this.AssociatedObject.Unloaded -= AssociatedObjectOnUnloaded;
            this.AssociatedObject.RequestNavigate -= NavigationRequested;
        }

        private void NavigationRequested(object sender, RequestNavigateEventArgs e)
        {
            if (!ConfirmNavigation || MessageBox.Show("Are you sure?", "Question", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)
            {
                OpenUrl();
            }

            e.Handled = true;
        }

        private void OpenUrl()
        {
//          Process.Start(new ProcessStartInfo(AssociatedObject.NavigateUri.AbsoluteUri));
            MessageBox.Show($"Opening {AssociatedObject.NavigateUri}");
        }

        /// <inheritdoc />
        protected override void OnDetaching()
        {
            this.AssociatedObject.RequestNavigate -= NavigationRequested;
            base.OnDetaching();
        }
    }
}

I my case, I was using syncthing. It created a duplicate that I was not aware of and my compilation was failing.

views.py

from django.contrib import messages 

def view_name(request):
    if request.method == 'POST':
        form = form_class(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
        else:
            messages.error(request, "Error")
return render(request, 'page.html', {'form':form_class()})

If you want to show the errors of the form other than that not valid just put {{form.as_p}} like what I did below

page.html

<html>
    <head>
        <script>
            {% if messages %}
                {% for message in messages %}
                    alert('{{message}}')
                {% endfor %}
            {% endif %}
        </script>
    </head>
    <body>
        {{form.as_p}}
    </body>
</html> 

I get this one all the time. It means that the user started to download a file, and then it either failed, or they cancelled it.

To reproduce the exception try do this yourself - however I'm unaware of any ways to prevent it (except for handling this specific exception only).

You need to decide what the best way forward is depending on your app.

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

In Powershell 3.0 and above there is both a Invoke-WebRequest and Invoke-RestMethod. Curl is actually an alias of Invoke-WebRequest in PoSH. I think using native Powershell would be much more appropriate than curl, but it's up to you :).

Invoke-WebRequest MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849901.aspx?f=255&MSPPError=-2147217396

Invoke-RestMethod MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849971.aspx?f=255&MSPPError=-2147217396

Note: If your issue is, "innodb index is marked as corrupted"! Then, the simple solution can be, just remove the indexes and add them again. That can solve pretty quickly without losing any records nor restarting or moving table contents into a temporary table and back.

To define a 3 column grid you could use the customizer or download the source set your less variables and recompile.

To learn more about the grid and the columns / gutter widths, please also read:

• Bootstrap 3 - Set Container Width to 940px Maximum for Desktops?
• Why does Bootstrap 3 force the container width to certain sizes?
• Bootstrap 3 Gutter Size
• Reduce the gutter (default 30px) on smaller devices in Bootstrap3?

In you case with a container of 960px consider the medium grid (see also: http://getbootstrap.com/css/#grid). This grid will have a max container width of 970px. When setting @grid-columns:3; and setting @grid-gutter-width:15px; in variables.less you will get:

15px | 1st column (298.33) | 15px | 2nd column (298.33) |15px | 3th column (298.33) | 15px

Oracle has announced fix for Windows XP installation error

Oracle has decided to fix Windows XP installation. As of the JRE 8u25 release in 10/15/2014 the code of the installer has been changes so that installation on Windows XP is again possible.

However, this does not mean that Oracle is continuing to support Windows XP. They make no guarantee about current and future releases of JRE8 being compatible with Windows XP. It looks like it's a run at your own risk kind of thing.

See the Oracle blog post here.

You can get the latest JRE8 right off the Oracle downloads site.

You need to take out your suffix rule (%.o: %.c) in favour of a big-bang rule. Something like this:

LIBS  = -lkernel32 -luser32 -lgdi32 -lopengl32
CFLAGS = -Wall

OBJ = 64bitmath.o    \
      monotone.o     \
      node_sort.o    \
      planesweep.o   \
      triangulate.o  \
      prim_combine.o \
      welding.o      \
      test.o         \
      main.o

SRCS = $(OBJ:%.o=%.c)

test: $(SRCS)
    gcc -o $@  $(CFLAGS) $(LIBS) $(SRCS)

If you're going to experiment with GCC's whole-program optimization, make sure that you add the appropriate flag to CFLAGS, above.

On reading through the docs for those flags, I see notes about link-time optimization as well; you should investigate those too.

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

Yes, I think performance-wise you might find a difference as bitwise left and right shift operations can be performed with a complexity of o(1) with a huge data set.

For example, calculating the power of 2 ^ n:

int value = 1;
while (exponent<n)
    {
       // Print out current power of 2
        value = value *2; // Equivalent machine level left shift bit wise operation
        exponent++;
         }
    }

Similar code with a bitwise left shift operation would be like:

value = 1 << n;

Moreover, performing a bit-wise operation is like exacting a replica of user level mathematical operations (which is the final machine level instructions processed by the microcontroller and processor).

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

Create database which gave error as Unknown database, Login to mysql shell:

sudo mysql -u root -p
create database db_name;

Now try restoring database using .sql file, -p flag will ask for a sql user's password once command is executed.

sudo mysql -u root -p db_name < db_name.sql

There's a lot more to abstract classes than default method implementations (such as private state), but as of Java 8, whenever you have the choice of either, you should go with the defender (aka. default) method in the interface.

The constraint on the default method is that it can be implemented only in the terms of calls to other interface methods, with no reference to a particular implementation's state. So the main use case is higher-level and convenience methods.

The good thing about this new feature is that, where before you were forced to use an abstract class for the convenience methods, thus constraining the implementor to single inheritance, now you can have a really clean design with just the interface and a minimum of implementation effort forced on the programmer.

The original motivation to introduce default methods to Java 8 was the desire to extend the Collections Framework interfaces with lambda-oriented methods without breaking any existing implementations. Although this is more relevant to the authors of public libraries, you may find the same feature useful in your project as well. You've got one centralized place where to add new convenience and you don't have to rely on how the rest of the type hierarchy looks.

I agree with shadow. You could use the onmouseover and onmouseout event to change the CSS via JavaScript.

And don't say people need to have JavaScript activated. It's only a style issue, so it doesn't matter if there are some visitors without JavaScript ;) Although most of Web 2.0 works with JavaScript. See Facebook for example (lots of JavaScript) or Myspace.

Is Java smart enough to skip checking bool2 and bool2 if bool1 was evaluated to false?

Its not a matter of being smart, its a requirement specified in the language. Otherwise you couldn't write expressions like.

if(s != null && s.length() > 0)

or

if(s == null || s.length() == 0)

BTW if you use & and | it will always evaluate both sides of the expression.

Use the following will help

keytool -import -v -trustcacerts -alias keyAlias -file server.cer -keystore cacerts.jks -keypass changeit

weak_ptr is also good to check the correct deletion of an object - especially in unit tests. Typical use case might look like this:

std::weak_ptr<X> weak_x{ shared_x };
shared_x.reset();
BOOST_CHECK(weak_x.lock());
... //do something that should remove all other copies of shared_x and hence destroy x
BOOST_CHECK(!weak_x.lock());

If you want to define a 3D matrix containing all zeros, you write

A = zeros(8,4,20);

All ones uses ones, all NaN's uses NaN, all false uses false instead of zeros.

If you have an existing 2D matrix, you can assign an element in the "3rd dimension" and the matrix is augmented to contain the new element. All other new matrix elements that have to be added to do that are set to zero.

For example

B = magic(3); %# creates a 3x3 magic square
B(2,1,2) = 1; %# and you have a 3x3x2 array

I have wondered about this in the past and came to the conclusion that it was not actually a valid test case for my code. I don't think your application code can actually tell the difference between somebody declining notifications the first time or later disabling it from the iPhone notification settings. It is true that the user experience is different but that is hidden inside the call to registerForRemoteNotificationTypes.

Calling unregisterForRemoteNotifications does not completely remove the application from the notifications settings - though it does remove the contents of the settings for that application. So this still will not cause the dialog to be presented a second time to the user the next time the app runs (at least not on v3.1.3 that I am currently testing with). But as I say above you probably should not be worrying about that.
