If you use CSS to select a monospace font, the problem of varying character length is easily solved.

Inspired by the function ELT(index number, string1, string2, string3,…),I think the following example works as an array example:

set @i := 1;
while @i <= 3
do
  insert into table(val) values (ELT(@i ,'val1','val2','val3'...));
set @i = @i + 1;
end while;

Hope it help.

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

After 7 long hours of searching I finally found the way!! None of the above solutions worked, only one of them pointed towards the issue!

If you are on Win7, then your Firewall blocks the SDK Manager from retrieving the addon list. You will have to add "android.bat" and "java.exe" to the trusted files and bingo! everything will start working!!

You can do this by casting the dict keys and values to list. It can also be be done for items.

Example:

f = {'one': 'police', 'two': 'oranges', 'three': 'car'}
list(f.keys())[0] = 'one'
list(f.keys())[1] = 'two'

list(f.values())[0] = 'police'
list(f.values())[1] = 'oranges'

This is how I solved it for a YearQuarter class I had to create. I created an __init__ which is very tolerant to a wide variety of input.

You use it like this:

>>> from datetime import date
>>> temp1 = YearQuarter(year=2017, month=12)
>>> print temp1
2017-Q4
>>> temp2 = YearQuarter(temp1)
>>> print temp2
2017-Q4
>>> temp3 = YearQuarter((2017, 6))
>>> print temp3
2017-Q2 
>>> temp4 = YearQuarter(date(2017, 1, 18))
>>> print temp4
2017-Q1
>>> temp5 = YearQuarter(year=2017, quarter = 3)
>>> print temp5
2017-Q3

And this is how the __init__ and the rest of the class looks like:

import datetime


class YearQuarter:

    def __init__(self, *args, **kwargs):
        if len(args) == 1:
            [x]     = args

            if isinstance(x, datetime.date):
                self._year      = int(x.year)
                self._quarter   = (int(x.month) + 2) / 3
            elif isinstance(x, tuple):
                year, month     = x

                self._year      = int(year)

                month           = int(month)

                if 1 <= month <= 12:
                    self._quarter   = (month + 2) / 3
                else:
                    raise ValueError

            elif isinstance(x, YearQuarter):
                self._year      = x._year
                self._quarter   = x._quarter

        elif len(args) == 2:
            year, month     = args

            self._year      = int(year)

            month           = int(month)

            if 1 <= month <= 12:
                self._quarter   = (month + 2) / 3
            else:
                raise ValueError

        elif kwargs:

            self._year      = int(kwargs["year"])

            if "quarter" in kwargs:
                quarter     = int(kwargs["quarter"])

                if 1 <= quarter <= 4:
                    self._quarter     = quarter
                else:
                    raise ValueError
            elif "month" in kwargs:
                month   = int(kwargs["month"])

                if 1 <= month <= 12:
                    self._quarter     = (month + 2) / 3
                else:
                    raise ValueError

    def __str__(self):
        return '{0}-Q{1}'.format(self._year, self._quarter)

mysql_fetch_assoc returns an array so you can not echo an array, need to print_r() otherwise particular string $money['money'].

All the download process is too long, just navigate to your project preview and select project view, right click on app folder, then click on new, then create a new image asset. Kindly choose the file path and click next and finish.

important: Reinstall your app.

I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.

Im attempting this now, this is what i came up with;

    placeholder = 1
    while placeholder is not None:
        try:
            #Code
            placeholder = None
        except Exception as e:
            print(str(datetime.time(datetime.now()))[:8] + str(e)) #To log the errors
            placeholder = e
            time.sleep(0.5)
            continue

In first activity u can send intent using startActivityForResult() and then get result from second activity after it finished using setResult.

MainActivity.class

public class MainActivity extends AppCompatActivity {

    private static final int SECOND_ACTIVITY_RESULT_CODE = 0;

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

    // "Go to Second Activity" button click
    public void onButtonClick(View view) {

        // Start the SecondActivity
        Intent intent = new Intent(this, SecondActivity.class);
        // send intent for result 
        startActivityForResult(intent, SECOND_ACTIVITY_RESULT_CODE);
    }

    // This method is called when the second activity finishes
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // check that it is the SecondActivity with an OK result
        if (requestCode == SECOND_ACTIVITY_RESULT_CODE) {
            if (resultCode == RESULT_OK) {

                // get String data from Intent
                String returnString = data.getStringExtra("keyName");

                // set text view with string
                TextView textView = (TextView) findViewById(R.id.textView);
                textView.setText(returnString);
            }
        }
    }
}

SecondActivity.class

public class SecondActivity extends AppCompatActivity {

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

    // "Send text back" button click
    public void onButtonClick(View view) {

        // get the text from the EditText
        EditText editText = (EditText) findViewById(R.id.editText);
        String stringToPassBack = editText.getText().toString();

        // put the String to pass back into an Intent and close this activity
        Intent intent = new Intent();
        intent.putExtra("keyName", stringToPassBack);
        setResult(RESULT_OK, intent);
        finish();
    }
}

The constructor of PetStore will call a constructor of Farm; there's no way you can prevent it. If you do nothing (as you've done), it will call the default constructor (Farm()); if you need to pass arguments, you'll have to specify the base class in the initializer list:

PetStore::PetStore()
    : Farm( neededArgument )
    , idF( 0 )
{
}

(Similarly, the constructor of PetStore will call the constructor of nameF. The constructor of a class always calls the constructors of all of its base classes and all of its members.)

None of the above worked for me. what worked for me is to go to File -> Invalidate Caches / Restart

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

Create an another <tr> just below and add some space or height to content of <td>

I tried ng remove component Comp_Name also ng distroy component but it is not yet supported by angular so the best option for now is to manually remove it from the folder structure.

for Laravel 5.4
for gmail

in .env file

MAIL_DRIVER=mail
MAIL_HOST=mail.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<username>@gmail.com
MAIL_PASSWORD=<password>
MAIL_ENCRYPTION=tls

in config/mail.php

'driver' => env('MAIL_DRIVER', 'mail'),

'from' => [
    'address' => env(
        'MAIL_FROM_ADDRESS', '<username>@gmail.com'
    ),
    'name' => env(
        'MAIL_FROM_NAME', '<from_name>'
    ),
],

You can use type() or isinstance().

>>> type([]) is list
True

Be warned that you can clobber list or any other type by assigning a variable in the current scope of the same name.

>>> the_d = {}
>>> t = lambda x: "aight" if type(x) is dict else "NOPE"
>>> t(the_d) 'aight'
>>> dict = "dude."
>>> t(the_d) 'NOPE'

Above we see that dict gets reassigned to a string, therefore the test:

type({}) is dict

...fails.

To get around this and use type() more cautiously:

>>> import __builtin__
>>> the_d = {}
>>> type({}) is dict
True
>>> dict =""
>>> type({}) is dict
False
>>> type({}) is __builtin__.dict
True

You can do it in a simpler way , like the below:

boolean IsEqualStringandEnum (String str,Enum enum)
{
  if (str.equals(enum.toString()))
     return true;
  else
     return false;
}

with open('writing_file.json', 'w') as w:
    with open('reading_file.json', 'r') as r:
        for line in r:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            w.write(json.dumps(element))

this is the method i use..

var day = value.Date; // a DateTime that will just be whole days
var time = value.TimeOfDay; // a TimeSpan that is the duration into the day

Better way:

encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )

To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI. For example, a user could type "Thyme &time=again" for a variable comment. Not using encodeURIComponent on this variable will give comment=Thyme%20&time=again. Note that the ampersand and the equal sign mark a new key and value pair. So instead of having a POST comment key equal to "Thyme &time=again", you have two POST keys, one equal to "Thyme " and another (time) equal to again.

For application/x-www-form-urlencoded (POST), per http://www.w3.org/TR/html401/interac...m-content-type, spaces are to be replaced by '+', so one may wish to follow a encodeURIComponent replacement with an additional replacement of "%20" with "+".

If one wishes to be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

function fixedEncodeURIComponent (str) {
  return encodeURIComponent(str).replace(/[!'()]/g, escape).replace(/\*/g, "%2A");
}

Change android:stretchColumns value to *.

Value 0 means stretch the first column. Value 1 means stretch the second column and so on.

Value * means stretch all the columns.

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

From http://psoug.org/reference/roles.html, create a procedure on your database for your user to do it:

CREATE OR REPLACE PROCEDURE GRANT_SELECT(to_user in varchar2) AS

  CURSOR ut_cur IS SELECT table_name FROM user_tables;

  RetVal  NUMBER;
  sCursor INT;
  sqlstr  VARCHAR2(250);

BEGIN
    FOR ut_rec IN ut_cur
    LOOP
      sqlstr := 'GRANT SELECT ON '|| ut_rec.table_name || ' TO ' || to_user;
      sCursor := dbms_sql.open_cursor;
      dbms_sql.parse(sCursor,sqlstr, dbms_sql.native);
      RetVal := dbms_sql.execute(sCursor);
      dbms_sql.close_cursor(sCursor);

    END LOOP;
END grant_select;

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

Have you tried passing the Update panel's client id to the __doPostBack function? My team has done this to refresh an update panel and as far as I know it worked.

__doPostBack(UpdatePanelClientID, '**Some String**');

First, it depends on your version of R. If you've passed 2.11, you can use aggreggate with multiple results functions(summary, by instance, or your own function). If not, you can use the answer made by Justin.

None of the answers they gave you was exhaustive. The problem lies in the Multidex. You must add the library in the app gradle :

implementation 'com.android.support:multidex:1.0.3'

After, add in the defaultConfig of the app gradle :

multiDexEnabled true

Your Application must be of the Multidex type.. You must write it in the manifest :

android:name=".MyApplication"

"MyApplication" must be either the Multidex class, or it must extend it.

I'm thinking unload is called all but at hard exist in 4.7. But, if you are playing around with older versions of .Net, try doing this in your loading method:

e.Handled = true;

I don't think older versions will unload until loading is handled. Just posting because I see others still asking this question, and haven't seen this proposed as a solution. I only touch .Net a few times a year, and ran into this a few years back. But, I wonder if it's as simple as unload not being called until loading has finished. Seems like it works for me, but again in newer .Net it seems to always call unload even if loading isn't marked as handled.

This error also occurs if you use four-space instead of two-space indentation.

e.g., the following would throw the error:

fields:
    - metadata: {}
        name: colName
        nullable: true

whereas changing indentation to two-spaces would fix it:

fields:
  - metadata: {}
    name: colName
    nullable: true

I had to tweak the Chrome launcher on macosx and added below script. Saved it as below;

/Applications/Google\ Chrome.app/Contents/MacOS/Chrome.command

#!/bin/sh
RealBin="Google Chrome"
AppDir="$(dirname "$0")"
exec "$AppDir/$RealBin" --ignore-certificate-errors "$@"

When I start Chrome with this script self-signed certificates are working without a problem. But don't browse the web with the browser launched with this script you will not be warned about invalid certificates!

Python is dynamic language so the IDE can do only so much in terms of code intelligence and syntax checking but I personally recommend Komode IDE, it's pretty slick on OS/X and Windows. I've experienced high cpu use with Linux but not sure if it's caused by my VirtualBox environment.

You can also try Eclipse with PyDev plugin. It's heavier so performance might become a problem though.

There is an add in the Datejs library.

And here are the JavaScript date methods. kennebec wisely mentioned getHours() and setHours();

You can use Scripting.FileSystemObject to do that thing. From the Reference:

The ReadLine method allows a script to read individual lines in a text file. To use this method, open the text file, and then set up a Do Loop that continues until the AtEndOfStream property is True. (This simply means that you have reached the end of the file.) Within the Do Loop, call the ReadLine method, store the contents of the first line in a variable, and then perform some action. When the script loops around, it will automatically drop down a line and read the second line of the file into the variable. This will continue until each line has been read (or until the script specifically exits the loop).

And a quick example:

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\FSO\ServerList.txt", 1)
Do Until objFile.AtEndOfStream
 strLine = objFile.ReadLine
 MsgBox strLine
Loop
objFile.Close

you can try typescript's For :

selectChildren(data , $event){
   let parentChecked : boolean = data.checked;
   for(let o of this.hierarchicalData){
      for(let child of o){
         child.checked = parentChecked;
      }
   }
}

Maven does this because your dependency is in a SNAPSHOT version and maven has no way to detect any changes made to that snapshot version in the repository. Release your artifact and change the version in pom.xml to that version and maven will no longer fetch the metadata file.

You can try using the following code to solve your problem:

 <activity
     android:name=".DonateNow"
     android:label="@string/title_activity_donate_now"
     android:screenOrientation="portrait"
     android:theme="@style/AppTheme"
     android:windowSoftInputMode="stateVisible|adjustPan">
 </activity>

just simply (PowerShell V5)

Get-ChildItem "C:\temp" -Recurse -File | Where CreationTime -lt  (Get-Date).AddDays(-15)  | Remove-Item -Force

Use Intellij plugin Sketch It!.

Here's a solution that is flexible and allows dups:

class String
  # generate a random string of length n using current string as the source of characters
  def random(n)
    return "" if n <= 0
    (chars * (n / length + 1)).shuffle[0..n-1].join  
  end
end

Example:

"ATCG".random(8) => "CGTGAAGA"

You can also allow a certain character to appear more frequently:

"AAAAATCG".random(10) => "CTGAAAAAGC"

Explanation: The method above takes the chars of a given string and generates a big enough array. It then shuffles it, takes the first n items, then joins them.

Something the other answers are missing is that it must be understood that Authentication and Authorization in the context of RFC 2616 refers ONLY to the HTTP Authentication protocol of RFC 2617. Authentication by schemes outside of RFC2617 is not supported in HTTP status codes and are not considered when deciding whether to use 401 or 403.

Brief and Terse

Unauthorized indicates that the client is not RFC2617 authenticated and the server is initiating the authentication process. Forbidden indicates either that the client is RFC2617 authenticated and does not have authorization or that the server does not support RFC2617 for the requested resource.

Meaning if you have your own roll-your-own login process and never use HTTP Authentication, 403 is always the proper response and 401 should never be used.

Detailed and In-Depth

From RFC2616

10.4.2 401 Unauthorized

The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8).

and

10.4.4 403 Forbidden The server understood the request but is refusing to fulfil it. Authorization will not help and the request SHOULD NOT be repeated.

The first thing to keep in mind is that "Authentication" and "Authorization" in the context of this document refer specifically to the HTTP Authentication protocols from RFC 2617. They do not refer to any roll-your-own authentication protocols you may have created using login pages, etc. I will use "login" to refer to authentication and authorization by methods other than RFC2617

So the real difference is not what the problem is or even if there is a solution. The difference is what the server expects the client to do next.

401 indicates that the resource can not be provided, but the server is REQUESTING that the client log in through HTTP Authentication and has sent reply headers to initiate the process. Possibly there are authorizations that will permit access to the resource, possibly there are not, but let's give it a try and see what happens.

403 indicates that the resource can not be provided and there is, for the current user, no way to solve this through RFC2617 and no point in trying. This may be because it is known that no level of authentication is sufficient (for instance because of an IP blacklist), but it may be because the user is already authenticated and does not have authority. The RFC2617 model is one-user, one-credentials so the case where the user may have a second set of credentials that could be authorized may be ignored. It neither suggests nor implies that some sort of login page or other non-RFC2617 authentication protocol may or may not help - that is outside the RFC2616 standards and definition.

Edit: RFC2616 is obsolete, see RFC7231 and RFC7235.

    cursor = fileSQLiteAdapter.queueAll();

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do 
            {
                String name = cursor.getString(cursor.getColumnIndex(FileSQLiteAdapter.KEY_CONTENT1));
                fileName.add(name);
            } while (cursor.moveToNext());
        }
        cursor.close();
    }

    fileSQLiteAdapter.close();

    return fileName;
}

Insert all n elements from an array to BST takes O(n logn). n elemnts in an array can be inserted to a heap in O(n) time. Which gives heap a definite advantage

If you have a Date (or Datetime) column, look at http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format

 SELECT DATE_FORMAT(datecolumn,'%d/%m/%Y') FROM ...

Should do the job for MySQL, for SqlServer I'm sure there is an analog function. If you have a VARCHAR column, you might have at first to convert it to a date, see STR_TO_DATE for MySQL.

It is only required if you aren't using the default values for version and encoding (which you are in that example).

bool is a fundamental datatype in C++. Converting true to an integer type will yield 1, and converting false will yield 0 (4.5/4 and 4.7/4). In C, until C99, there was no bool datatype, and people did stuff like

enum bool {
    false, true
};

So did the Windows API. Starting with C99, we have _Bool as a basic data type. Including stdbool.h will typedef #define that to bool and provide the constants true and false. They didn't make bool a basic data-type (and thus a keyword) because of compatibility issues with existing code.

Check out the opensource Forge project. It provides a JavaScript TLS implementation, along with some Flash to handle the actual cross-domain requests:

http://github.com/digitalbazaar/forge/blob/master/README

In short, Forge will enable you to make XmlHttpRequests from a web page loaded over http to an https site. You will need to provide a Flash cross-domain policy file via your server to enable the cross-domain requests. Check out the blog posts at the end of the README to get a more in-depth explanation for how it works.

However, I should mention that Forge is better suited for requests between two different https-domains. The reason is that there's a potential MiTM attack. If you load the JavaScript and Flash from a non-secure site it could be compromised. The most secure use is to load it from a secure site and then use it to access other sites (secure or otherwise).

You Can Use

string txt = "                   i am a string                                    ";
txt = txt.TrimStart().TrimEnd();

Output is "i am a string"

I know this is not the OP's problem, but I ran into the same error with an entirely different basis, so I just wanted to drop it here in case anyone else has the same. This is Windows-specific, and I assume does not affect Linux users.

I had a LibreOffice doc file, call it final report.odt. I later changed its case to Final Report.odt. In Windows, this doesn't even count as a rename. final report.odt, Final Report.odt, FiNaL RePoRt.oDt are all the same. In Linux, these are all distinct.

When I eventually went to git rm "Final Report.odt" and got the "pathspec did not match any files" error. Only when I use the original casing at the time the file was added -- git rm "final report.odt" -- did it work.

Lesson learned: to change the case I should have instead done:

git mv "final report.odt" temp.odt
git mv temp.odt "Final Report.odt"

Again, that wasn't the problem for the OP here; and wouldn't affect a Linux user, as his posts shows he clearly is. I'm just including it for others who may have this problem in Windows git and stumble onto this question.

For your own specific server or different pages & image button you could use something like this (PHP only)

<a href="http://www.facebook.com/sharer/sharer.php?u=http://'.$_SERVER['SERVER_NAME'].'" target="_blank"><img src="http://i.stack.imgur.com/rffGp.png" /></a>

I cannot share the snippet with this but you will get the idea...

That's not possible.

The alternative is using reflection:

 Class.forName("SomeClass").getMethod("someMethod").invoke(null);

Arrays.asList(array);    

Example:

 List<String> stooges = Arrays.asList("Larry", "Moe", "Curly");

See Arrays.asList class documentation.

By far the simplest command for this is:

git show --name-only

As it lists just the files in the last commit and doesn't give you the entire guts

An example of the output being:

For me it was changing.

To what computed returns so;

this.$store.state.name = response.data;

In your mobile device,make sure you have enabled the following buttons.

If column is not NOT NULL (nullable).

You just put NULL instead of value in INSERT statement.

There's no major problem with while(true) with break statements, however some may think its slightly lowers the code readability. Try to give variables meaningful names, evaluate expressions in the proper place.

For your example, it seems much clearer to do something like:

do {
   input = get_input();
   valid = check_input_validity(input);    
} while(! valid)

This is especially true if the do while loop gets long -- you know exactly where the check to see if there's an extra iteration is occurring. All variables/functions have appropriate names at the level of abstraction. The while(true) statement does is tell you that processing isn't in the place you thought.

Maybe you want different output on the second time through the loop. Something like

input = get_input();
while(input_is_not_valid(input)) {
    disp_msg_invalid_input();
    input = get_input();
}

seems more readable to me then

do {
    input = get_input();
    if (input_is_valid(input)) {
        break;
    }
    disp_msg_invalid_input();
} while(true);

Again, with a trivial example both are quite readable; but if the loop became very large or deeply nested (which means you probably should already have refactored), the first style may be a bit clearer.

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

I assume you want to know the performance difference between the following:

WHERE foo IN ('a', 'b', 'c')
WHERE foo = 'a' OR foo = 'b' OR foo = 'c'

According to the manual for MySQL if the values are constant IN sorts the list and then uses a binary search. I would imagine that OR evaluates them one by one in no particular order. So IN is faster in some circumstances.

The best way to know is to profile both on your database with your specific data to see which is faster.

I tried both on a MySQL with 1000000 rows. When the column is indexed there is no discernable difference in performance - both are nearly instant. When the column is not indexed I got these results:

SELECT COUNT(*) FROM t_inner WHERE val IN (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000);
1 row fetched in 0.0032 (1.2679 seconds)

SELECT COUNT(*) FROM t_inner WHERE val = 1000 OR val = 2000 OR val = 3000 OR val = 4000 OR val = 5000 OR val = 6000 OR val = 7000 OR val = 8000 OR val = 9000;
1 row fetched in 0.0026 (1.7385 seconds)

So in this case the method using OR is about 30% slower. Adding more terms makes the difference larger. Results may vary on other databases and on other data.

It's not possible, sorry. If really needed, you could use a jQuery plugin to have a custom alert.

I got this problem, and tried many ways to solve it. Finally, it turned out that make clean and make again solved it. The reason is: I got the source code together with object files compiled previously with an old gcc version. When my newer gcc version wants to link that old object files, it can't resolve some function in there. It happens to me several times that the source code distributors do not clean up before packing, so a make clean saved the day.

Yet another try - Using event lambda expressions

As form initializes a single event handler can be assigned to all controls of type RadioButton in a group box, and use .tabIndex or .tag property to identify what option is checked when it changes.

This way you can subscribe to any of the events of each radio button in one go

int priceOption = 0;
foreach (RadioButton rbtn in grp_PriceOpt.Controls.OfType<RadioButton>())
{
    rbtn.CheckedChanged += (o, e) =>
    {
        var button = (RadioButton)o;
        if (button.Checked)
        {
            priceOption = button.TabIndex;
        }
    };
}

As events are assigned to radio buttons only, no type checking of sender is implemented.

Also notice as we loop all buttons this could be a perfect moment to assign data properties, change text etc.

function date_conversion(start_date){
    var formattedDate = new Date(start_date);
    var d = formattedDate.getDate();
    var m =  formattedDate.getMonth();
    var month;
    m += 1;  // JavaScript months are 0-11
    switch (m) {
        case 1: {

I was having similar issues connecting to OpenSUSE 13.1 MySQL database with LibreOffice. Update LibreOffice to latest stable "Still" package, then make sure the database is accessible using a tool such as phpMyAdmin. Make sure your user is linked to localhost and not "%" (any). This worked for me, I am able to add data thru LibreOffice.

Side note - LibreOffice Base will not supply "native connection" via MySQL on first attempt, you will need to use the back button, then try again to see the options.

Hope this helps.

If you don`t want to create a manifest just to run the jar file, you can reference the main-class directly from the command line when you run the jar file.

java -jar Predit.jar -classpath your.package.name.Test

This sets the which main-class to run in the jar file.

Just use Hour and Minute properties

var date = DateTime.Now;
date.Hour;
date.Minute;

Or you can easily zero the seconds using

var zeroSecondDate = date.AddSeconds(-date.Second);

You need to escape < and &. Escaping > too doesn't hurt:

function magic(input) {
    input = input.replace(/&/g, '&');
    input = input.replace(/</g, '&lt;');
    input = input.replace(/>/g, '&gt;');
    return input;
}

Or you let the DOM engine do the dirty work for you (using jQuery because I'm lazy):

function magic(input) {
    return $('<span>').text(input).html();
}

What this does is creating a dummy element, assigning your string as its textContent (i.e. no HTML-specific characters have side effects since it's just text) and then you retrieve the HTML content of that element - which is the text but with special characters converted to HTML entities in cases where it's necessary.

You can get the icons from the android sdk they are in this folder

Assuming you are using ssh to connect rsync, what about to send a ssh command before:

if it already exists, nothing happens

When using forms,we can use 'return false' to prevent submitting.

function checkForm() {
    // return true to submit, return false to prevent submitting
}
<form onsubmit="return checkForm()">
    ...
</form>

var x = y !== undefined ? y : 1;

Note that var x = y || 1; would assign 1 for any case where y is falsy (e.g. false, 0, ""), which may be why it "didn't work" for you. Also, if y is a global variable, if it's truly not defined you may run into an error unless you access it as window.y.

As vol7ron suggests in the comments, you can also use typeof to avoid the need to refer to global vars as window.<name>:

var x = typeof y != "undefined" ? y : 1;

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

I think it has changed again.

For posting this works in Xcode 8.2.

NotificationCenter.default.post(Notification(name:.UIApplicationWillResignActive)

I have tried almost all of the ways as in answers given. But neither DateTime nor date_create gave me correct answers in all my test cases. Specially test with February & March dates or December & January dates.

So, I came-up with mixed solution.

public static function getMonthsDaysDiff($fromDate, $toDate, $includingEnding = false){
    $d1=new DateTime($fromDate);
    $d2=new DateTime($toDate);
    if($includingEnding === true){
        $d2 = $d2->modify('+1 day');
    }
    $diff = $d2->diff($d1);
    $months = (($diff->format('%y') * 12) + $diff->format('%m'));

    $lastSameDate = $d1->modify("+$months month");
    $days = date_diff(
        date_create($d2->format('Y-m-d')),
        date_create($lastSameDate->format('Y-m-d'))
    )->format('%a');

    $return = ['months' => $months,
        'days' => $days];
}

I know, performance wise this quite expensive. And you can extend it to get Years as well.

In short slug help get rid of those ugly looking urls with valid-urls for examples in an ecommerec site instead of showing the url as www.myecom.com/product/5432156 i can show it like www.myecom.com/product/iphone11 with the help of slug

@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.

movieClipName.addEventListener(MouseEvent.CLICK, callLink);

  var url:String = "http://site";
  var request:URLRequest = new URLRequest(url);
  try {
    navigateToURL(request, '_blank');
  } catch (e:Error) {
    trace("Error occurred!");
  }

In my experience, I often encounter the following situations;

1. If you work in a corporate company, contact the network and security team. Because in requests made to external services, it may be necessary to give permission for the relevant endpoint.

2. Another issue is that the SSL certificate may have expired on the server where your application is running.

Self Answer (pretty much summary of other's comments and answers):

• In RStudio, Esc works, on windows, Mac, and ubuntu (and I would guess on other linux distributions as well).

• If the process is ran in say ubuntu shell (and this is not R specific), for example using:

  Rscript my_file.R
  

  Ctrl + c kills the process

  Ctrl + z suspends the process

• Within R shell, Ctrl + C kills helps you escape it

After a long struggle, I found the solution.

Solution: Add a reference to System.Net.Http.Formatting.dll. This assembly is also available in the C:\Program Files\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies folder.

The method ReadAsAsync is an extension method declared in the class HttpContentExtensions, which is in the namespace System.Net.Http in the library System.Net.Http.Formatting.

Reflector came to rescue!

Can be done without the constants (like 3600000 ms is 1h)

public static Date addMinutesToDate(Date date, int minutes) {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        calendar.add(Calendar.MINUTE, minutes);
        return calendar.getTime();
    }

public static Date addHoursToDate(Date date, int hours) {
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(date);
    calendar.add(Calendar.HOUR_OF_DAY, hours);
    return calendar.getTime();
}

example of usage:

System.out.println(new Date());
System.out.println(addMinutesToDate(new Date(), 5));

There are a few issues in your code

• <div [formGroup]="form"> outside of a <form> tag
• <form [formGroup]="form"> but the name of the property containing the FormGroup is loginForm therefore it should be <form [formGroup]="loginForm">
• [formControlName]="dob" which passes the value of the property dob which doesn't exist. What you need is to pass the string dob like [formControlName]="'dob'" or simpler formControlName="dob"

Plunker example

Because it is a query, only percent escaped characters work, means %0A gives you a line break. For example,

<a href="mailto:[email protected]?Subject=TEST&body=Hi there,%0A%0AHow are you?%0A%0AThanks">email to me</a>

How can I change where Vagrant looks for its virtual hard drive?

the virtual-machine state is stored in a predefined VirtualBox folder. Copying the corresponding machine (folder) besides your vagrant-project to your other host should preserve your virtual machine state.

Swift

Specific font

Setting a specific font in Swift is done like this:

let myFont = UIFont(name: "Helvetica", size: 17)

If you don't know the name, you can get a list of the available font names like this:

print(UIFont.familyNames())

Or an even more detailed list like this:

for familyName in UIFont.familyNames() {
    print(UIFont.fontNamesForFamilyName(familyName))
}

But the system font changes from version to version of iOS. So it would be better to get the system font dynamically.

System font

let myFont = UIFont.systemFontOfSize(17)

But we have the size hard-coded in. What if the user's eyes are bad and they want to make the font larger? Of course, you could make a setting in your app for the user to change the font size, but this would be annoying if the user had to do this separately for every single app on their phone. It would be easier to just make one change in the general settings...

Dynamic font

let myFont = UIFont.preferredFont(forTextStyle: .body)

Ah, now we have the system font at the user's chosen size for the Text Style we are working with. This is the recommended way of setting the font. See Supporting Dynamic Type for more info on this.

You can do this without moment.js

A way to do this in native Javascript code :

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

firstDay = moment(firstDay).format(yourFormat);
lastDay = moment(lastDay).format(yourFormat);

Hai Vu answer works great, just one comment:

In case you are using the global in other module and you want to set the global dynamically, pay attention to import the other modules after you set the global variables, for example:

# settings.py
def init(arg):
    global myList
    myList = []
    mylist.append(arg)


# subfile.py
import settings

def print():
    settings.myList[0]


# main.py
import settings
settings.init("1st")     # global init before used in other imported modules
                         # Or else they will be undefined

import subfile    
subfile.print()          # global usage

You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.

In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.

sudo yum remove kubeadm kubectl kubelet kubernetes-cni kube*


# on debian base

You have to merge your files first. Do a git status to see what are the files that need to be merged (means you need to resolve the conflicts first). Once this is done, do git add file_merged and do your pull again.

Convert.ToInt32 allows null value, it doesn't throw any errors Int.parse does not allow null value, it throws an ArgumentNullException error.

You should install as described here:

pip install image

No, it won't work.

document.getElementById() method accepts only one argument.

However, you may always set classes to the elements and use getElementsByClassName() instead. Another option for modern browsers is to use querySelectorAll() method:

document.querySelectorAll("#myCircle1, #myCircle2, #myCircle3, #myCircle4");

Just adding some addition aspects. Need for setting seed: In the academic world, if one claims that his algorithm achieves, say 98.05% performance in one simulation, others need to be able to reproduce it.

?set.seed

Going through the help file of this function, these are some interesting facts:

(1) set.seed() returns NULL, invisible

(2) "Initially, there is no seed; a new one is created from the current time and the process ID when one is required. Hence different sessions will give different simulation results, by default. However, the seed might be restored from a previous session if a previously saved workspace is restored.", this is why you would want to call set.seed() with same integer values the next time you want a same sequence of random sequence.

This may also be caused by using the xDebug bookmarks when debugging the page. Just stop debugger (remove cookie) and it will go back to normal.

The task above can be completed in two simple steps.

STEP 1:

CREATE table new_table_name AS(Select * from old_table_name);

The query above creates a duplicate of a table (with contents as well).

To get the structure, delete the contents of the table using.

STEP 2:

DELETE * FROM new_table_name.

Hope this solves your problem. And thanks to the earlier posts. Gave me a lot of insight.

I found that even though it worked on my dev box, the assembly wasn't added to the project. Search for Microsoft.Web.Infrastructure in NuGet and install it from there. Then, make sure it has Copy Local selected.

I think it's better to avoid the situation. It's cleaner and clearer to write:

a = None

    a = 42

Use the Len function

import React, {Component} from 'react';
import {
     AppRegistry, StyleSheet, View, Text, Image
     ToastAndroid
} from 'react-native';
import * as Progress from 'react-native-progress';

export default class RNClass extends Component{
     constructor(props){
          super(props);

          this.state= {
               uri: this.props.uri,
               loading:false
          }
     }

     renderLoadingView(){
          return(
               <View style={{justifyContent:'center',alignItems:'center',flex:1}}>
                    <Progress.Circle size={30} indeterminate={true} />
                    <Text>
                        Loading Data...
                    </Text>
               </View>
          );
     }

     renderLoadedView(){
          return(
               <View>

               </View>
          );
     }

     fetchData(){
          fetch(this.state.uri)
               .then((response) => response.json())
               .then((result)=>{

               })
               .done();

               this.setState({
                         loading:true
               });
               this.renderLoadedView();
     }

     componentDidMount(){
          this.fetchData();
     }

     render(){
          if(!this.state.loading){
               return(
                    this.renderLoadingView()
               );
          }

          else{

               return(
                    this.renderLoadedView()
               );
          }
     }
}

var style = StyleSheet.create({

});

private static byte[] charArrayToByteArray(char[] c_array) {
        byte[] b_array = new byte[c_array.length];
        for(int i= 0; i < c_array.length; i++) {
            b_array[i] = (byte)(0xFF & (int)c_array[i]);

I pasted your code into test project, added about 20 items and I get usable scroll bars, no problem, and they work as expected. When I only add a couple items (such that scrolling is unnecessary) I get no usable scrollbar. Could this be the case? that you are not adding enough items?

If you remove the ScrollViewer.VerticalScrollBarVisibility="Visible" then the scroll bars only appear when you have need of them.

So I found that if you are compiling from Visual Studios you just have to exclude the included .cpp file from the final build (that which you are extending from):

Visual Studios: .cpp file > right click > properties > configuration properties > general > excluded from build > yes

I believe you can also exclude the file when compiling from the command line.

This works for me

TestService.ReconstitutionClient _serv = new TestService.TestClient();

using (OperationContextScope contextScope = new OperationContextScope(_serv.InnerChannel))
{
   HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();

   requestMessage.Headers["apiKey"] = ConfigurationManager.AppSettings["apikey"]; 
   OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = 
      requestMessage;
   _serv.Method(Testarg);
}

  width: 100%    !important;

Quote_Month (Worksheet!$D:$D) contains a formula (=TEXT(Worksheet!$E:$E,"mmm-yy"))to convert a date/time number from another column into a text based month reference.

You can use OR by adding + in Sumproduct. See this

=SUMPRODUCT((Quote_Value)*(Salesman="JBloggs")*(Days_To_Close<=90)*((Quote_Month="Cond1")+(Quote_Month="Cond2")+(Quote_Month="Cond3")))

ScreenShot

By using docker-compose:

Assuming that you have following directory layout:

$MYAPP_ROOT/docker-compose.yml
           /Docker/init.sql
           /Docker/db.Dockerfile

File: docker-compose.yml

version: "3.3"
services:
  db:
    build:
      context: ./Docker
      dockerfile: db.Dockerfile
    volumes:
      - ./var/pgdata:/var/lib/postgresql/data
    ports:
      - "5432:5432"

File: Docker/init.sql

CREATE USER myUser;

CREATE DATABASE myApp_dev;
GRANT ALL PRIVILEGES ON DATABASE myApp_dev TO myUser;

CREATE DATABASE myApp_test;
GRANT ALL PRIVILEGES ON DATABASE myApp_test TO myUser;

File: Docker/db.Dockerfile

FROM postgres:11.5-alpine
COPY init.sql /docker-entrypoint-initdb.d/

Composing and starting services:

docker-compose -f docker-compose.yml up --no-start
docker-compose -f docker-compose.yml start

sed doesn't recognize \d, use [[:digit:]] instead. You will also need to escape the + or use the -r switch (-E on OS X).

Note that [0-9] works as well for Arabic-Hindu numerals.

Sounds like you're overthinking it. You've observed the difference between childNodes and children, which is that childNodes contains all nodes, including text nodes consisting entirely of whitespace, while children is a collection of just the child nodes that are elements. That's really all there is to it.

There is nothing unpredictable about either collection, although there are a couple of issues to be aware of:

• IE <= 8 do not include white space-only text nodes in childNodes while other browsers do
• IE <= 8 includes comment nodes within children while other browsers only have elements

children, firstElementChild and friends are just conveniences, presenting a filtered view of the DOM restricted to just elements.

We do it this way...

String.prototype.getValueByKey = function (k) {
    var p = new RegExp('\\b' + k + '\\b', 'gi');
    return this.search(p) != -1 ? decodeURIComponent(this.substr(this.search(p) + k.length + 1).substr(0, this.substr(this.search(p) + k.length + 1).search(/(&|;|$)/))) : "";
};

The following code will help you to get the element of the mouse pointer. The resulted elements will display in the console.

document.addEventListener('mousemove', function(e) {
    console.log(document.elementFromPoint(e.pageX, e.pageY)); 
})

You can do this with the scp command, which uses the ssh protocol to copy files across machines. It extends the syntax of cp to allow references to other systems:

scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file

Copy something from this machine to some other machine:

scp /path/to/local/file username@hostname:/path/to/remote/file

Copy something from another machine to this machine:

scp username@hostname:/path/to/remote/file /path/to/local/file

Copy with a port number specified:

scp -P 1234 username@hostname:/path/to/remote/file /path/to/local/file

Add the outerheight to the top and you have the bottom, relative to the parent element:

var $el = $('#bottom');  //record the elem so you don't crawl the DOM everytime  
var bottom = $el.position().top + $el.outerHeight(true); // passing "true" will also include the top and bottom margin

With absolutely positioned elements or when positioning relative to the document, you will need to instead evaluate using offset:

var bottom = $el.offset().top + $el.outerHeight(true);

As pointed out by trnelson this does not work 100% of the time. To use this method for positioned elements, you also must account for offset. For an example see the following code.

var bottom = $el.position().top + $el.offset().top + $el.outerHeight(true);

React uses the className attribute, like the DOM.

If you use the development build, and look at the console, there's a warning. You can see this on the jsfiddle.

Warning: Unknown DOM property class. Did you mean className?

$('html, body').animate({scrollTop:1200},'50');

You can do this!

This works for me:

start: function(event, ui) {
        var start_pos = ui.item.index();
        ui.item.data('start_pos', start_pos);
    },
update: function (event, ui) {
        var start_pos = ui.item.data('start_pos');
        var end_pos = ui.item.index();
        //$('#sortable li').removeClass('highlights');
    }

Uri myUri = Uri.parse("http://www.google.com");

Here's the doc http://developer.android.com/reference/android/net/Uri.html#parse%28java.lang.String%29

Using Bootstrap, the correct way is to use the offset class. Use math to determine the left offset. Example: You want a button full width on mobile, but 1/3 width and centered on tablet, desktop, large desktop.

So out of 12 "bootstrap" columns, you're using 4 to offset, 4 for the button, then 4 is blank to the right.

See if that works!

Implementation with Guzzle library:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$httpClient = new Client();

$response = $httpClient->post(
    'https://postman-echo.com/post',
    [
        RequestOptions::BODY => 'POST raw request content',
        RequestOptions::HEADERS => [
            'Content-Type' => 'application/x-www-form-urlencoded',
        ],
    ]
);

echo(
    $response->getBody()->getContents()
);

PHP CURL extension:

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
    CURLOPT_URL => 'https://postman-echo.com/post',
    CURLOPT_RETURNTRANSFER => true,

    /**
     * Specify POST method
     */
    CURLOPT_POST => true,

    /**
     * Specify request content
     */
    CURLOPT_POSTFIELDS => 'POST raw request content',
]);

$response = curl_exec($curlHandler);

curl_close($curlHandler);

echo($response);

Source code

target.Value will give you a Variant type

target.Value2 will give you a Variant type as well but a Date is coerced to a Double

target.Text attempts to coerce to a String and will fail if the underlying Variant is not coercable to a String type

The safest thing to do is something like

Dim v As Variant
v = target.Value 'but if you don't want to handle date types use Value2

And check the type of the variant using VBA.VarType(v) before you attempt an explicit coercion.

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

None of these answers worked for me, when all I had was a list of directories. Then I stumbled upon the solution! You have to add -r to --files-from because -a will not be recursive in this scenario (who knew?!).

rsync -aruRP --files-from=directory.list . ../new/location

Create the symlink to latest version

 ln -s -f /usr/local/bin/python3.8 /usr/local/bin/python

Close and open a new terminal

and try

 python --version

List<String> stringList = getMyListOfStrings();
StringJoiner sj = new StringJoiner(" ");
stringList.stream().forEach(e -> sj.add(e));
String spaceSeparated = sj.toString()

You pass to the new StringJoiner the char sequence you want to be used as separator. If you want to do a CSV: new StringJoiner(", ");

I think the most efficient way is to wrap the touchableOpacity with a view and add the prop pointerEvents with a style condition.

<View style={this.state.disabled && commonStyles.buttonDisabled}        
      pointerEvents={this.state.disabled ? "none" : "auto"}>
  <TouchableOpacity
    style={styles.connectButton}>
  <Text style={styles.connectButtonText}">CONNECT </Text>
  </TouchableOpacity>
</View>

CSS:

buttonDisabled: {
    opacity: 0.7
  }

Php has a super sexy function for this, just pass the array to it:

$json = json_encode($var);

$.ajax({
url:"Example.php",
type:"POST",
dataType : "json",
success:function(msg){
    console.info(msg);
}
});

simples :)

You might have 10,000 users total, but that's not the same as concurrent users. In this context, concurrent scripts being run.

For example, if your visitor visits index.php, and it makes a database query to get some user details, that request might live for 250ms. You can limit how long those MySQL connections live even further by opening and closing them only when you are querying, instead of leaving it open for the duration of the script.

While it is hard to make any type of formula to predict how many connections would be open at a time, I'd venture the following:

You probably won't have more than 500 active users at any given time with a user base of 10,000 users. Of those 500 concurrent users, there will probably at most be 10-20 concurrent requests being made at a time.

That means, you are really only establishing about 10-20 concurrent requests.

As others mentioned, you have nothing to worry about in that department.

You can annotate a class or a method with SuppressWarnings

@java.lang.SuppressWarnings("squid:S00112")

squid:S00112 in this case is a Sonar issue ID. You can find this ID in the Sonar UI. Go to Issues Drilldown. Find an issue you want to suppress warnings on. In the red issue box in your code is there a Rule link with a definition of a given issue. Once you click that you will see the ID at the top of the page.

ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;

script/runner and rake tasks are perfectly fine to run as cron jobs.

Here's one very important thing you must remember when running cron jobs. They probably won't be called from the root directory of your app. This means all your requires for files (as opposed to libraries) should be done with the explicit path: e.g. File.dirname(__FILE__) + "/other_file". This also means you have to know how to explicitly call them from another directory :-)

Check if your code supports being run from another directory with

# from ~
/path/to/ruby /path/to/app/script/runner -e development "MyClass.class_method"
/path/to/ruby /path/to/rake -f /path/to/app/Rakefile rake:task RAILS_ENV=development

Also, cron jobs probably don't run as you, so don't depend on any shortcut you put in .bashrc. But that's just a standard cron tip ;-)

$startinfo = new-object System.Diagnostics.ProcessStartInfo 
$startinfo.FileName = "explorer.exe"
$startinfo.WorkingDirectory = 'D:\foldername'

[System.Diagnostics.Process]::Start($startinfo)

Hope this helps

Use JSONP.

jQuery:

$.ajax({
     url:"testserver.php",
     dataType: 'jsonp', // Notice! JSONP <-- P (lowercase)
     success:function(json){
         // do stuff with json (in this case an array)
         alert("Success");
     },
     error:function(){
         alert("Error");
     }      
});

PHP:

<?php
$arr = array("element1","element2",array("element31","element32"));
$arr['name'] = "response";
echo $_GET['callback']."(".json_encode($arr).");";
?>

The echo might be wrong, it's been a while since I've used php. In any case you need to output callbackName('jsonString') notice the quotes. jQuery will pass it's own callback name, so you need to get that from the GET params.

And as Stefan Kendall posted, $.getJSON() is a shorthand method, but then you need to append 'callback=?' to the url as GET parameter (yes, value is ?, jQuery replaces this with its own generated callback method).

See this example: https://jsfiddle.net/pqhdce2L/

Sadly, they want us to use a tag to let their browser know what to do. Look at this documentation, it tell us to use:

<meta http-equiv="X-UA-Compatible" content="IE=edge" >

and it should do.

There is no show event in js - you need to bind your button either to the click event:

$('#id').on('click', function (e) {

     //your awesome code here

})

Mind that if your button is inside a form, you may prefer to bind the whole form to the submit event.

Be careful if you are working on localhost ! If you store your cookie in js like this:

document.cookie = "key=value;domain=localhost"

It might not be accessible to your subdomain, like sub.localhost. In order to solve this issue you need to use Virtual Host. For exemple you can configure your virtual host with ServerName localhost.com then you will be able to store your cookie on your domain and subdomain like this:

document.cookie = "key=value;domain=localhost.com"

In my case, I went for

MySQL install Uninstall only the MySQL Server Install again

Make sure the Path is the same for example (if your installer warns you of a conflict): C:\Program Files...etc... C:\Program Files...etc...

If they are the same, it should work fine.

==========================================================

==========================================================

Ctrl-w f .......... open file under cursor in new window

btn-group-justified and btn-group only work for static content but not on dynamically created buttons, and fixed with of button in css is not practical as it stay on the same width even all content are short.

My solution: put the same class to group of buttons then loop to all of them, get the width of the longest button and apply it to all

var bwidth=0
$("button.btnGroup").each(function(i,v){
    if($(v).width()>bwidth) bwidth=$(v).width();
});
$("button.btnGroup").width(bwidth);

If you are trying to compare two algorithms, do at least two benchmarks for each, alternating the order. i.e.:

for(i=1..n)
  alg1();
for(i=1..n)
  alg2();
for(i=1..n)
  alg2();
for(i=1..n)
  alg1();

I have found some noticeable differences (5-10% sometimes) in the runtime of the same algorithm in different passes..

Also, make sure that n is very large, so that the runtime of each loop is at the very least 10 seconds or so. The more iterations, the more significant figures in your benchmark time and the more reliable that data is.

After trying everything here twice in different order, I reinstalled everything and before doing cordova platform add android I went to templates/gradle and ran gradlew.bat. After this completed, I was able to add the android platform without any problem.

mongoose.connect(`mongodb://localhost/${dbname}`, {
        useNewUrlParser: true,
        useCreateIndex: true,
        useFindAndModify: true,
        useUnifiedTopology: true
    })
        .then((connection) => {
            mongoose.connection.db.dropDatabase();
        });

To delete a complete database, just pass the name... This one is working perfectly fine on version 4.4

NoClassDefFound error is a nebulous error and is often hiding a more serious issue. It is not the same as ClassNotFoundException (which is thrown when the class is just plain not there).

NoClassDefFound may indicate the class is not there, as the javadocs indicate, but it is typically thrown when, after the classloader has loaded the bytes for the class and calls "defineClass" on them. Also carefully check your full stack trace for other clues or possible "cause" Exceptions (though your particular backtrace shows none).

The first place to look when you get a NoClassDefFoundError is in the static bits of your class i.e. any initialization that takes place during the defining of the class. If this fails it will throw a NoClassDefFoundError - it's supposed to throw an ExceptionInInitializerError and indicate the details of the problem but in my experience, these are rare. It will only do the ExceptionInInitializerError the first time it tries to define the class, after that it will just throw NoClassDefFound. So look at earlier logs.

I would thus suggest looking at the code in that HibernateTransactionInterceptor line and seeing what it is requiring. It seems that it is unable to define the class SpringFactory. So maybe check the initialization code in that class, that might help. If you can debug it, stop it at the last line above (17) and debug into so you can try find the exact line that is causing the exception. Also check higher up in the log, if you very lucky there might be an ExceptionInInitializerError.

Not quite as pretty as the JQuery example by Marco but with prototype (i may be missing a more elegant solution) it would be:

function sort_select(select) {
  var options = $A(select.options).sortBy(function(o) { return o.innerHTML });
  select.innerHTML = "";
  options.each(function(o) { select.insert(o); } );
}

And then just pass it a select element:

sort_select( $('category-select') );

return 1 << $a << $b << $c >= 1 << 2;

I had almost the same problem, but with the following variation:

1. I've imported a ready-to-use maven project into Eclipse IDE from PC1 (project was working there perfectly) to another PC2
2. when was trying to run the project on PC 2 got the same error "Could not find or load main class"
3. I've checked PATH variable (it had many values in my case) and added JAVA_HOME variable (in my case it was JAVA_HOME = C:\Program Files\Java\jdk1.7.0_03) After restarting Ecplise it still didn't work
4. I've tried to run simple HelloWorld.java on PC2 (in another project) - it worked
5. So I've added HelloWorld class to the imported recently project, executed it there and - huh - my main class in that project started to run normally also.

That's quite odd behavour, I cannot completely understand it. Hope It'll help somebody. too.

As seen on this example from Twitter, add this before the line that includes the responsive styles declarations:

<style> 
    body {
        padding-top: 60px;
    }
</style>

Like so:

<link href="Z/bootstrap/css/bootstrap.min.css" rel="stylesheet" />
<style type="text/css">
    body {
        padding-top: 60px;
    }
</style>
<link href="Z/bootstrap/css/bootstrap-responsive.min.css" rel="stylesheet" />

You can do more than just fall through in C#, but you must utilize the "dreaded" goto statement. For example:

switch (whatever)
{
  case 2:
    Result.Write( "Subscribe" );
    break;
  case 1:
    Result.Write( "Un" );
    goto case 2;
}

WKWebView: I find this question to be the best place to let people know that they should start using WKWebview as UIWebView is now deprecated.

Objective C

WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.frame];
webView.navigationDelegate = self;
NSURL *nsurl=[NSURL URLWithString:@"https://www.example.com/document.pdf"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
[self.view addSubview:webView];

Swift

let myURLString = "https://www.example.com/document.pdf"
let url = NSURL(string: myURLString)
let request = NSURLRequest(URL: url!)  
let webView = WKWebView(frame: self.view.frame)
webView.navigationDelegate = self
webView.loadRequest(request)
view.addSubview(webView)

I haven't copied this code directly from Xcode, so it might, it might contain some syntax error. Please check while using it.

You can increase security in authentication process by using JWT (JSON Web Tokens) and SSL/HTTPS.

The Basic Auth / Session ID can be stolen via:

• MITM attack (Man-In-The-Middle) - without SSL/HTTPS
• An intruder gaining access to a user's computer
• XSS

By using JWT you're encrypting the user's authentication details and storing in the client, and sending it along with every request to the API, where the server/API validates the token. It can't be decrypted/read without the private key (which the server/API stores secretly) Read update.

The new (more secure) flow would be:

Login

• User logs in and sends login credentials to API (over SSL/HTTPS)
• API receives login credentials
• If valid:
  • Register a new session in the database Read update
  • Encrypt User ID, Session ID, IP address, timestamp, etc. in a JWT with a private key.
• API sends the JWT token back to the client (over SSL/HTTPS)
• Client receives the JWT token and stores in localStorage/cookie

Every request to API

• User sends a HTTP request to API (over SSL/HTTPS) with the stored JWT token in the HTTP header
• API reads HTTP header and decrypts JWT token with its private key
• API validates the JWT token, matches the IP address from the HTTP request with the one in the JWT token and checks if session has expired
• If valid:
  • Return response with requested content
• If invalid:
  • Throw exception (403 / 401)
  • Flag intrusion in the system
  • Send a warning email to the user.

Updated 30.07.15:

JWT payload/claims can actually be read without the private key (secret) and it's not secure to store it in localStorage. I'm sorry about these false statements. However they seem to be working on a JWE standard (JSON Web Encryption).

I implemented this by storing claims (userID, exp) in a JWT, signed it with a private key (secret) the API/backend only knows about and stored it as a secure HttpOnly cookie on the client. That way it cannot be read via XSS and cannot be manipulated, otherwise the JWT fails signature verification. Also by using a secure HttpOnly cookie, you're making sure that the cookie is sent only via HTTP requests (not accessible to script) and only sent via secure connection (HTTPS).

Updated 17.07.16:

JWTs are by nature stateless. That means they invalidate/expire themselves. By adding the SessionID in the token's claims you're making it stateful, because its validity doesn't now only depend on signature verification and expiry date, it also depends on the session state on the server. However the upside is you can invalidate tokens/sessions easily, which you couldn't before with stateless JWTs.

You need to import PIL (Pillow) for this. Suppose you have an image of size 1200, 1600. We will crop image from 400, 400 to 800, 800

from PIL import Image
img = Image.open("ImageName.jpg")
area = (400, 400, 800, 800)
cropped_img = img.crop(area)
cropped_img.show()

EDIT: This answer (and most of the others) are obsolete; see Devpool's answer instead.

Originally, there were no config options to make "git diff --ignore-submodules" and "git status --ignore-submodules" the global default (but see also Setting git default flags on commands). An alternative is to set a default ignore config option on each individual submodule you want to ignore (for both git diff and git status), either in the .git/config file (local only) or .gitmodules (will be versioned by git). For example:

[submodule "foobar"]
    url = [email protected]:foo/bar.git
    ignore = untracked

ignore = untracked to ignore just untracked files, ignore = dirty to also ignore modified files, and ignore = all to ignore also commits. There's apparently no way to wildcard it for all submodules.

This is my solution for your reference:

struct Foo
{
    Foo(){}//used to make compiler happy!
    Foo(int x){/*...*/}
};

struct Bar
{
    Foo foo[3];

    Bar()
    {
        //initialize foo array here:
        for(int i=0;i<3;++i)
        {
            foo[i]=Foo(4+i);
        }
    }
};

For just a boolean match result or for a count of occurrences, you could use:

use 5.014; use strict; use warnings;
my @foo=('hello', 'world', 'foo', 'bar', 'hello world', 'HeLlo');
my $patterns=join(',',@foo);
for my $str (qw(quux world hello hEllO)) {
    my $count=map {m/^$str$/i} @foo;
    if ($count) {
        print "I found '$str' $count time(s) in '$patterns'\n";
    } else {
        print "I could not find '$str' in the pattern list\n"
    };
}

Output:

I could not find 'quux' in the pattern list
I found 'world' 1 time(s) in 'hello,world,foo,bar,hello world,HeLlo'
I found 'hello' 2 time(s) in 'hello,world,foo,bar,hello world,HeLlo'
I found 'hEllO' 2 time(s) in 'hello,world,foo,bar,hello world,HeLlo'

Does not require to use a module.
Of course it's less "expandable" and versatile as some code above.
I use this for interactive user answers to match against a predefined set of case unsensitive answers.

Best description i've encounter so far is available on Oracle website.

Java SE's API provides the core functionality of the Java programming language. It defines everything from the basic types and objects of the Java programming language to high-level classes that are used for networking, security, database access, graphical user interface (GUI) development, and XML parsing.

The Java EE platform is built on top of the Java SE platform. The Java EE platform provides an API and runtime environment for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.

If you consider developing application using for example Spring Framework you will use both API's and would have to learn key concept of JavaServer Pages and related technologies like for ex.: JSP, JPA, JDBC, Dependency Injection etc.

From the mysql documentation version: 8.0.18:

A superuser account 'root'@'localhost' is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command: shell> sudo grep 'temporary password' /var/log/mysqld.log Change the root password as soon as possible by logging in with the generated, temporary password and set a custom password for the superuser account:

shell> mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

Do your trouble shooting in controlled steps:

(1) Does the script looks ok?

DOS E:\trials\SoTrials\SoDbTrials\MySQLScripts
type ansi.sql
show databases

(2) Can you connect to your database (even without specified the host)?

DOS E:\trials\SoTrials\SoDbTrials\MySQLScripts
mysql -u root -p mysql
Enter password: ********
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 9
Server version: 5.0.51b-community-nt MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

(3) Can you source the script? (Hoping for more/better error info)

mysql> source ansi.sql
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ...                |
| test               |
+--------------------+
7 rows in set (0.01 sec)
mysql> quit
Bye

(4) Why does it (still not) work?

DOS E:\trials\SoTrials\SoDbTrials\MySQLScripts
mysql -u root -p mysql < ansi.sql
Enter password: ********
Database
information_schema
...
test

I suspected that the encoding of the script could be the culprit, but I got syntax errors for UTF8 or UTF16 encoded files:

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near '´++
show databases' at line 1

This could be a version thing; so I think you should make sure of the encoding of your script.

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

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

In swift 4.2 I used following code to show and hide code using NSNotification

 @objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo? [UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        let keyboardheight = keyboardSize.height
        print(keyboardheight)
    }
}

You don't need to create a button. The facility exists by default.

Just right click on the arrow buttons on the bottom left hand corner of the Excel window. These are the arrow buttons which if you left click move left or right one worksheet.

If you right-click on these arrows Excel will pop up a dialogue with a list of worksheets from which you can click to set your chosen sheet active.

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

Googling around for Groovy ways to "cast" a String to a Date, I came across this article: http://www.goodercode.com/wp/intercept-method-calls-groovy-type-conversion/

The author uses Groovy metaMethods to allow dynamically extending the behavior of any class' asType method. Here is the code from the website.

class Convert {
    private from
    private to

    private Convert(clazz) { from = clazz }
    static def from(clazz) {
        new Convert(clazz)
    }

    def to(clazz) {
        to = clazz
        return this
    }

    def using(closure) {
        def originalAsType = from.metaClass.getMetaMethod('asType', [] as Class[])
        from.metaClass.asType = { Class clazz ->
            if( clazz == to ) {
                closure.setProperty('value', delegate)
                closure(delegate)
            } else {
                originalAsType.doMethodInvoke(delegate, clazz)
            }
        }
    }
}

They provide a Convert class that wraps the Groovy complexity, making it trivial to add custom as-based type conversion from any type to any other:

Convert.from( String ).to( Date ).using { new java.text.SimpleDateFormat('MM-dd-yyyy').parse(value) }

def christmas = '12-25-2010' as Date

It's a convenient and powerful solution, but I wouldn't recommend it to someone who isn't familiar with the tradeoffs and pitfalls of tinkering with metaClasses.

It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.

Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.

DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj

...

The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.

var DyObjectsList = new List<dynamic>; 
if (condition1) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = true; 
    DyObj.Message = "Message 1"; 
    DyObjectsList .Add(DyObj); 
} 
if (condition2) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = false; 
    DyObj.Message = "Message 2"; 
    DyObjectsList .Add(DyObj); 
} 

your resulting List essentially looks like this

DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj

Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.

However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.

I just had this problem and it seems to be related to permissions somehow. I initially unzipped it to my Program Files folder, in Windows 8. After unzipping it directly to C: the program started normally.

I know this is an old question and I probably won't help, but many Linux distributions(e.g., ubuntu) have a "Live cd/usb" function, so if you really need to run this script, you could try booting your computer into Linux. Just burn a .iso to a flash drive (here's how http://goo.gl/U1wLYA), start your computer with the drive plugged in, and press the F key for boot menu. If you choose "...USB...", you will boot into the OS you just put on the drive.

Correction

Some python3 one-liners that work with any number of bytes.

Decoding hex (with strip, so that it's ok to have a newline on stdin):

$ echo 666f6f0a | python3 -c "import sys, binascii; sys.stdout.buffer.write(binascii.unhexlify(input().strip()))"
foo

Encoding hex:

$ echo foo | python3 -c "import sys, binascii; print(binascii.hexlify(sys.stdin.buffer.read()).decode())"
666f6f0a

copying the jar files will resolve. If by any chance you are copying the code from any tutorials, make sure the class names are spelled in correct case...for example i copied a code from one of the tutorials which had solr in S cap. Eclipse was continiously throwing the error and i also did a bit of googling ...everything was ok and it took 30 mins for me to realise the cap small issue. Am sure this will help someone

Here is what I use when I don't have access to the source string, e.g. for downloaded HTML:

// replace newlines with <br>
public static String replaceNewlinesWithBreaks(String source) {
    return source != null ? source.replaceAll("(?:\n|\r\n)","<br>") : "";
}

For XML you should probably edit that to replace with <br/> instead.

Example of its use in a function (additional calls removed for clarity):

// remove HTML tags but preserve supported HTML text styling (if there is any)
public static CharSequence getStyledTextFromHtml(String source) {
    return android.text.Html.fromHtml(replaceNewlinesWithBreaks(source));
}

...and a further example:

textView.setText(getStyledTextFromHtml(someString));

Anything that is not stored on an EBS volume that is mounted to the instance will be lost.

For example, if you mount your EBS volume at /mystuff, then anything not in /mystuff will be lost. If you don't mount an ebs volume and save stuff on it, then I believe everything will be lost.

You can create an AMI from your current machine state, which will contain everything in your ephemeral storage. Then, when you launch a new instance based on that AMI it will contain everything as it is now.

Update: to clarify based on comments by mattgmg1990 and glenn bech:

Note that there is a difference between "stop" and "terminate". If you "stop" an instance that is backed by EBS then the information on the root volume will still be in the same state when you "start" the machine again. According to the documentation, "By default, the root device volume and the other Amazon EBS volumes attached when you launch an Amazon EBS-backed instance are automatically deleted when the instance terminates" but you can modify that via configuration.

This one is working for me.

func stringByAddingPercentEncodingForFormData(plusForSpace: Bool=false) -> String? {
    let unreserved = "*-._"
    let allowed = NSMutableCharacterSet.alphanumericCharacterSet()
    allowed.addCharactersInString(unreserved)

    if plusForSpace {
        allowed.addCharactersInString(" ")
    }

    var encoded = stringByAddingPercentEncodingWithAllowedCharacters(allowed)
    if plusForSpace {
        encoded = encoded?.stringByReplacingOccurrencesOfString(" ",
                                                                withString: "+")
    }
    return encoded
}

I found the above function from this link: http://useyourloaf.com/blog/how-to-percent-encode-a-url-string/

You can also use this function with swift extension. Please let me know if there is any issue.

I would suggest you have a look at BackgroundWorker. If you have a loop that large in your WinForm it will block and your app will look like it has hanged.

Look at BackgroundWorker.ReportProgress() to see how to report progress back to the UI thread.

For example:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;
    progressBar1.Value = 0;
    backgroundWorker.RunWorkerAsync();
}

private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);
        backgroundWorker.ReportProgress((j * 100) / 100000);
    }
}

private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // TODO: do something with final calculation.
}

This one did it for me:

var input = $("<input>")
               .attr("type", "hidden")
               .attr("name", "mydata").val("bla");
$('#form1').append(input);

is based on the Daff's answer, but added the NAME attribute to let it show in the form collection and changed VALUE to VAL Also checked the ID of the FORM (form1 in my case)

used the Firefox firebug to check whether the element was inserted.

Hidden elements do get posted back in the form collection, only read-only fields are discarded.

Why bother replicating the effect? Just draw a UIToolbar behind your view.

myView.backgroundColor = [UIColor clearColor];
UIToolbar* bgToolbar = [[UIToolbar alloc] initWithFrame:myView.frame];
bgToolbar.barStyle = UIBarStyleDefault;
[myView.superview insertSubview:bgToolbar belowSubview:myView];

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Tomcat sets a catalina.home system property. You can use this in your log4j properties file. Something like this:

log4j.rootCategory=DEBUG,errorfile

log4j.appender.errorfile.File=${catalina.home}/logs/LogFilename.log

On Debian (including Ubuntu), ${catalina.home} will not work because that points at /usr/share/tomcat6 which has no link to /var/log/tomcat6. Here just use ${catalina.base}.

If your using another container, try to find a similar system property, or define your own. Setting the system property will vary by platform, and container. But for Tomcat on Linux/Unix I would create a setenv.sh in the CATALINA_HOME/bin directory. It would contain:

export JAVA_OPTS="-Dcustom.logging.root=/var/log/webapps"

Then your log4j.properties would be:

log4j.rootCategory=DEBUG,errorfile

log4j.appender.errorfile.File=${custom.logging.root}/LogFilename.log

Actually, you are looking for the AJAX CALL, in which you will replace the URL parameter value with the link of the JSON file to get the JSON values.

$.ajax({
    url: "File.json", //the path of the file is replaced by File.json
    dataType: "json",
    success: function (response) {
        console.log(response); //it will return the json array
    }
});

Assert allows you to assert a condition (post or pre) applies in your code. It's a way of documenting your intentions and having the debugger inform you with a dialog if your intention is not met.

Unlike a breakpoint, the Assert goes with your code and can be used to add additional detail about your intention.

my approach works without a library and with cropped maps. Means it works with just parts from a Mercator image. Maybe it helps somebody: https://stackoverflow.com/a/10401734/730823

I think you are casting in the wrong direction though... if the method returns a list of TestA objects, then it really isn't safe to cast them to TestB.

Basically you are asking the compiler to let you perform TestB operations on a type TestA that does not support them.

I am a new to WPF, but not in .NET.

I have spent five hours trying to add a PNG file to a "WPF Custom Control Library Project" in .NET 3.5 (Visual Studio 2010) and setting it as a background of an image-inherited control.

Nothing relative with URIs worked. I can not imagine why there is no method to get a URI from a resource file, through IntelliSense, maybe as:

Properties.Resources.ResourceManager.GetURI("my_image");

I've tried a lot of URIs and played with ResourceManager, and Assembly's GetManifest methods, but all there were exceptions or NULL values.

Here I pot the code that worked for me:

// Convert the image in resources to a Stream
Stream ms = new MemoryStream()
Properties.Resources.MyImage.Save(ms, ImageFormat.Png);

// Create a BitmapImage with the stream.
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = ms;
bitmap.EndInit();

// Set as source
Source = bitmap;

Got this one:

^[1-9]|[0-9]{2,}$

Someone beats it? :)

To understand sed command, we have to build it step by step.

Here is your original text

user@linux:~$ echo "Here is a String"
Here is a String
user@linux:~$ 

Let's try to remove Here string with substition option in sed

user@linux:~$ echo "Here is a String" | sed 's/Here //'
is a String
user@linux:~$ 

At this point, I believe you would be able to remove String as well

user@linux:~$ echo "Here is a String" | sed 's/String//'
Here is a
user@linux:~$ 

But this is not your desired output.

To combine two sed commands, use -e option

user@linux:~$ echo "Here is a String" | sed -e 's/Here //' -e 's/String//'
is a
user@linux:~$ 

Hope this helps

Actually something like

function scrollTo(prop){
    $('html,body').animate({scrollTop: $("#"+prop).offset().top +
 parseInt($("#"+prop).css('padding-top'),10) },'slow');
}

will work nicely and support padding. You can also support margins easily - for completion see below

function scrollTo(prop){
    $('html,body').animate({scrollTop: $("#"+prop).offset().top 
+ parseInt($("#"+prop).css('padding-top'),10) 
+ parseInt($("#"+prop).css('margin-top'),10) +},'slow');
}

You can upgrade your Java 7 version to 1.7.0_131-b31

For JRE 1.7.0_131-b31 in Oracle site :

TLSv1.2 and TLSv1.1 are now enabled by default on the TLS client end-points. This is similar behavior to what already happens in JDK 8 releases.

Looks like you are running afoul of this rule for updating views from Books Online: "INSERT statements must specify values for any columns in the underlying table that do not allow null values and have no DEFAULT definitions."

Here is my updated code. Checks to see if version exists before saving and saves as the next available version number.

Sub SaveNewVersion()
    Dim fileName As String, index As Long, ext As String
    arr = Split(ActiveWorkbook.Name, ".")
    ext = arr(UBound(arr))

    fileName = ActiveWorkbook.FullName

    If InStr(ActiveWorkbook.Name, "_v") = 0 Then
        fileName = ActiveWorkbook.Path & "\" & Left(ActiveWorkbook.Name, InStr(ActiveWorkbook.Name, ".") - 1) & "_v1." & ext
    End If

   Do Until Len(Dir(fileName)) = 0

        index = CInt(Split(Right(fileName, Len(fileName) - InStr(fileName, "_v") - 1), ".")(0))
        index = index + 1
        fileName = Left(fileName, InStr(fileName, "_v") - 1) & "_v" & index & "." & ext

    'Debug.Print fileName
   Loop

    ActiveWorkbook.SaveAs (fileName)
End Sub

    Workbooks.Open Filename:="Path(Ex: C:\Reports\ClientWiseReport.xls)"ReadOnly:=True


    For Each Sheet In ActiveWorkbook.Sheets

        Sheet.Copy After:=ThisWorkbook.Sheets(1)

    Next Sheet

I think in this case you want something like this:

$(window).resize(resize=function resize(){ some code...}

Now u can call resize() within some other nested functions:

$(window).scroll(function(){ resize();}
