Try using Math.abs:

variableAbs = Math.abs(variable);

For square root use:

variableSqRt = Math.sqrt(variable);

You'll want something like this to increase the message size quotas, in the App.config or Web.config file:

<bindings>
    <basicHttpBinding>
        <binding name="basicHttp" allowCookies="true"
                 maxReceivedMessageSize="20000000" 
                 maxBufferSize="20000000"
                 maxBufferPoolSize="20000000">
            <readerQuotas maxDepth="32" 
                 maxArrayLength="200000000"
                 maxStringContentLength="200000000"/>
        </binding>
    </basicHttpBinding>
</bindings>

And use the binding name in your endpoint configuration e.g.

...
bindingConfiguration="basicHttp"
...

The justification for the values is simple, they are sufficiently large to accommodate most messages. You can tune that number to fit your needs. The low default value is basically there to prevent DOS type attacks. Making it 20000000 would allow for a distributed DOS attack to be effective, the default size of 64k would require a very large number of clients to overpower most servers these days.

I would rather not use any outside frameworks like log4j.net.

Why? Log4net would probably address most of your requirements. For example check this class: RollingFileAppender.

Log4net is well documented and there are thousand of resources and use cases on the web.

New answer to an old question:

Method 1:

Step 1: You have to put /show after the URL you are working on:

http://jsfiddle.net/<fiddle_id>/show/ 

It shows the output with a result header.

Step 2: Right click the bottom frame and select View Frame Source. That's it. You got the html code with online JS links, CSS.

Just Save it.

For Example: http://jsfiddle.net/YRafQ/20/show/ for the site http://jsfiddle.net/YRafQ/20/

Note: View Frame Source and not View Page Source

Method 2:

You can use this code: view-source:http://fiddle.jshell.net/<fiddle_id>/show/light/

For Example: For my fiddle_id: YRafQ/20

view-source:http://fiddle.jshell.net/YRafQ/20/show/light/

try this

var json = [{
    "id" : "1", 
    "msg"   : "hi",
    "tid" : "2013-05-05 23:35",
    "fromWho": "[email protected]"
},
{
    "id" : "2", 
    "msg"   : "there",
    "tid" : "2013-05-05 23:45",
    "fromWho": "[email protected]"
}];

json.forEach((item) => {
  console.log('ID: ' + item.id);
  console.log('MSG: ' + item.msg);
  console.log('TID: ' + item.tid);
  console.log('FROMWHO: ' + item.fromWho);
});

Best and most generic way to control the music is to create a mother Activity in which you override startActivity(Intent intent) - in it you put shouldPlay=true, and onBackPressed() - in it you put shouldPlay = true. onStop - in it you put a conditional mediaPlayer.stop with shouldPlay as condition

Then, just extend the mother activity to all other activities, and no code duplicating is needed.

You may use this in shell:

wget -r --no-parent http://abc.tamu.edu/projects/tzivi/repository/revisions/2/raw/tzivi/

The Parameters are:

-r     //recursive Download

and

--no-parent // Don´t download something from the parent directory

If you don't want to download the entire content, you may use:

-l1 just download the directory (tzivi in your case)

-l2 download the directory and all level 1 subfolders ('tzivi/something' but not 'tivizi/somthing/foo')  

And so on. If you insert no -l option, wget will use -l 5 automatically.

If you insert a -l 0 you´ll download the whole Internet, because wget will follow every link it finds.

The compiler actually adds an argument to non-static methods. It adds a this pointer/reference. This is also the reason why a static method can not use this, because there is no object.

Unless I'm misunderstanding, you lost your .ssh directory containing your private key on your local machine and so you want to remove the public key which was on a server and which allowed key-based login.

In that case, it will be stored in the .ssh/authorized_keys file in your home directory on the server. You can just edit this file with a text editor and delete the relevant line if you can identify it (even easier if it's the only entry!).

I hope that key wasn't your only method of access to the server and you have some other way of logging in and editing the file. You can either manually add a new public key to authorised_keys file or use ssh-copy-id. Either way, you'll need password authentication set up for your account on the server, or some other identity or access method to get to the authorized_keys file on the server.

ssh-add adds identities to your SSH agent which handles management of your identities locally and "the connection to the agent is forwarded over SSH remote logins, and the user can thus use the privileges given by the identities anywhere in the network in a secure way." (man page), so I don't think it's what you want in this case. It doesn't have any way to get your public key onto a server without you having access to said server via an SSH login as far as I know.

You will need these imports...

import javax.servlet.*;
import javax.servlet.http.*;

And, if you're using Maven, you'll also need this in the dependencies block of the pom.xml file in your project's base directory.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Then the above-listed fix by Jason will work:

@ResponseBody
    public ResponseEntity<Boolean> saveData(HttpServletRequest request,
        HttpServletResponse response, Model model){
        String jsonString = request.getParameter("json");
    }

To perform a linear regression between two vectors x and y follow these steps:

[p,err] = polyfit(x,y,1);   % First order polynomial
y_fit = polyval(p,x,err);   % Values on a line
y_dif = y - y_fit;          % y value difference (residuals)
SSdif = sum(y_dif.^2);      % Sum square of difference
SStot = (length(y)-1)*var(y);   % Sum square of y taken from variance
rsq = 1-SSdif/SStot;        % Correlation 'r' value. If 1.0 the correlelation is perfect

For x=[10;200;7;150] and y=[0.001;0.45;0.0007;0.2] I get rsq = 0.9181.

First, there is no particularly good reason to use fdopen if fopen is an option and open is the other possible choice. You shouldn't have used open to open the file in the first place if you want a FILE *. So including fdopen in that list is incorrect and confusing because it isn't very much like the others. I will now proceed to ignore it because the important distinction here is between a C standard FILE * and an OS-specific file descriptor.

There are four main reasons to use fopen instead of open.

1. fopen provides you with buffering IO that may turn out to be a lot faster than what you're doing with open.
2. fopen does line ending translation if the file is not opened in binary mode, which can be very helpful if your program is ever ported to a non-Unix environment (though the world appears to be converging on LF-only (except IETF text-based networking protocols like SMTP and HTTP and such)).
3. A FILE * gives you the ability to use fscanf and other stdio functions.
4. Your code may someday need to be ported to some other platform that only supports ANSI C and does not support the open function.

In my opinion the line ending translation more often gets in your way than helps you, and the parsing of fscanf is so weak that you inevitably end up tossing it out in favor of something more useful.

And most platforms that support C have an open function.

That leaves the buffering question. In places where you are mainly reading or writing a file sequentially, the buffering support is really helpful and a big speed improvement. But it can lead to some interesting problems in which data does not end up in the file when you expect it to be there. You have to remember to fclose or fflush at the appropriate times.

If you're doing seeks (aka fsetpos or fseek the second of which is slightly trickier to use in a standards compliant way), the usefulness of buffering quickly goes down.

Of course, my bias is that I tend to work with sockets a whole lot, and there the fact that you really want to be doing non-blocking IO (which FILE * totally fails to support in any reasonable way) with no buffering at all and often have complex parsing requirements really color my perceptions.

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

This is more or less a summary of three answers (by Sara Inés Calderón, klaxon and Gothburz), but as they all added something important, I consider it worth joining the solutions and adding some more explanation.

Considering your example, you can do calculations in your template using:

{{ 100 * (count/total) }}

However, this may result in a whole lot of decimal places, so using filters is a good way to go:

{{ 100 * (count/total) | number }}

By default, the number filter will leave up to three fractional digits, this is where the fractionSize argument comes in quite handy ({{ 100 * (count/total) | number:fractionSize }}), which in your case would be:

{{ 100 * (count/total) | number:0 }}

This will also round the result already:

angular.module('numberFilterExample', [])_x000D_
  .controller('ExampleController', ['$scope',_x000D_
    function($scope) {_x000D_
      $scope.val = 1234.56789;_x000D_
    }_x000D_
  ]);

<html lang="en">_x000D_
  <head>  _x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_

    <table ng-controller="ExampleController">_x000D_
      <tr>_x000D_
        <td>No formatting:</td>_x000D_
        <td>_x000D_
          <span>{{ val }}</span>_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>3 Decimal places:</td>_x000D_
        <td>_x000D_
          <span>{{ val | number }}</span> (default)_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>2 Decimal places:</td>_x000D_
        <td><span>{{ val | number:2 }}</span></td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>No fractions: </td>_x000D_
        <td><span>{{ val | number:0 }}</span> (rounded)</td>_x000D_
      </tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

Last thing to mention, if you rely on an external data source, it probably is good practise to provide a proper fallback value (otherwise you may see NaN or nothing on your site):

{{ (100 * (count/total) | number:0) || 0 }}

Sidenote: Depending on your specifications, you may even be able to be more precise with your fallbacks/define fallbacks on lower levels already (e.g. {{(100 * (count || 10)/ (total || 100) | number:2)}}). Though, this may not not always make sense..

here is how you can do it through list comprehension, but this will waste a little bit of your computer's memory as line.strip() has been called twice.

     with open('textfile.txt') as file:
lines =[
            line.strip()
            for line in file
             if line.strip() != '']
print("number of lines =  {}".format(len(lines)))

if your array is built from a database query, you can change the key directly from the mysql statement:

instead of

"select ´id´ from ´tablename´..."

use something like:

"select ´id´ **as NEWNAME** from ´tablename´..."

xmlns - xml namespace. It's just a method to avoid element name conflicts. For example:

<config xmlns:rnc="URI1" xmlns:bsc="URI2">
  <rnc:node>
      <rnc:rncId>5</rnc:rncId>
  </rnc:node>

  <bsc:node>
      <bsc:cId>5</bsc:cId>
  </bsc:node>
</config>

Two different node elements in one xml file. Without namespaces this file would not be valid.

In my case it was Avast Antivirus interfering with the connection. Actions to disable this feature: Avast -> Settings-> Components -> Mail Shield (Customize) -> SSL scanning -> uncheck "Scan SSL connections".

In CurrentGame component you need to change initial state because you are trying use loop for participants but this property is undefined that's why you get error.,

getInitialState: function(){
    return {
       data: {
          participants: [] 
       }
    };
},

also, as player in .map is Object you should get properties from it

this.props.data.participants.map(function(player) {
   return <li key={player.championId}>{player.summonerName}</li>
   // -------------------^^^^^^^^^^^---------^^^^^^^^^^^^^^
})

Example

I've used a DOS command line to do this. Two lines, actually. The first one to make the "current directory" the folder where the file is - or the root folder of a group of folders where the file can be. The second line does the search.

CD C:\TheFolder
C:\TheFolder>FINDSTR /L /S /I /N /C:"TheString" *.PRG

You can find details about the parameters at this link.

Hope it helps!

Expression you are looking for may be:

...
return any( isinstance(e, list) for e in my_list )

Testing:

>>> my_list = [1,2]
>>> any( isinstance(e, list) for e in my_list )
False
>>> my_list = [1,2, [3,4,5]]
>>> any( isinstance(e, list) for e in my_list )
True
>>> 

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

In our databases we use an enum that ensures we pass it either TRUE or FALSE. If you do it either of the first two ways it is too easy to either start adding new meaning to the integer without going through a proper design, or ending up with that char field having Y, y, N, n, T, t, F, f values and having to remember which section of code uses which table and which version of true it is using.

I think you've got one major problem here: there's no monotonically increasing "counter" to guarantee that a given row has happened later in time than another. Take this example:

timestamp   lives_remaining   user_id   trans_id
10:00       4                 3         5
10:00       5                 3         6
10:00       3                 3         1
10:00       2                 3         2

You cannot determine from this data which is the most recent entry. Is it the second one or the last one? There is no sort or max() function you can apply to any of this data to give you the correct answer.

Increasing the resolution of the timestamp would be a huge help. Since the database engine serializes requests, with sufficient resolution you can guarantee that no two timestamps will be the same.

Alternatively, use a trans_id that won't roll over for a very, very long time. Having a trans_id that rolls over means you can't tell (for the same timestamp) whether trans_id 6 is more recent than trans_id 1 unless you do some complicated math.

I believe Twitter Bootstrap has a class called clearfix that you can use to clear the floating.

<ul class="nav nav-tabs span2 clearfix">

Well, in my case I had to test a Phone Number with the help of regex, and I was getting the same error,

Invalid regular expression: /+923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/: Nothing to repeat'

So, what was the error in my case was that + operator after the / in the start of the regex. So enclosing the + operator with square brackets [+], and again sending the request, worked like a charm.

Following will work:

/[+]923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/

This answer may be helpful for those, who got the same type of error, but their chances of getting the error from this point of view, as mine! Cheers :)

You can reload using /etc/init.d/nginx reload and sudo service nginx reload

If nginx -t throws some error then it won't reload

so use && to run both at a same time

like

nginx -t && /etc/init.d/nginx reload

In my case everything was set up correctly but still the InfoPlist.strings file was not found.

The only thing that really worked was, to remove and add the InfoPlist.strings files again to the project.

Elegant solution for finding a value (http://betamode.de/2013/10/17/laravel-4-eloquent-check-if-there-is-a-model-with-certain-key-value-pair-in-a-collection/) can be adapted:

$desired_object_key = $food->array_search(24, $food->lists('id'));
if ($desired_object_key !== false) {
   $desired_object = $food[$desired_object_key];
}

The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods. The transaction is rolled back on any error, or if it is disposed without first being committed. Try/Catch error handling is used to handle any errors when attempting to commit or roll back the transaction.

private static void ExecuteSqlTransaction(string connectionString)
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();

        SqlCommand command = connection.CreateCommand();
        SqlTransaction transaction;

        // Start a local transaction.
        transaction = connection.BeginTransaction("SampleTransaction");

        // Must assign both transaction object and connection 
        // to Command object for a pending local transaction
        command.Connection = connection;
        command.Transaction = transaction;

        try
        {
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
            command.ExecuteNonQuery();
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
            command.ExecuteNonQuery();

            // Attempt to commit the transaction.
            transaction.Commit();
            Console.WriteLine("Both records are written to database.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Commit Exception Type: {0}", ex.GetType());
            Console.WriteLine("  Message: {0}", ex.Message);

            // Attempt to roll back the transaction. 
            try
            {
                transaction.Rollback();
            }
            catch (Exception ex2)
            {
                // This catch block will handle any errors that may have occurred

Just do a simple .keys()

...     "1": "a", 
...     "3": "b", 
...     "8": {
...         "12": "c",

... }
>>> 
>>> dct.keys()
['1', '8', '3']
>>> for key in dct.keys(): print key
...
1
8
3
>>>

If you need a sorted list:

keylist = dct.keys()
keylist.sort()

Try this formula (it will return value from A1 as is if it's not a date):

=TEXT(A1,"mm-yyyy")

Or this formula (it's more strict, it will return #VALUE error if A1 is not date):

=TEXT(MONTH(A1),"00")&"-"&YEAR(A1)

My team encountered the same issue in machines with Windows.. then managed to resolve it in two ways:

a) Set enviroment variable (even in Windows system preferences)

JAVA_TOOL_OPTIONS
-Dfile.encoding=UTF8

b) Introduce following snippet to your pom.xml:

 -Dfile.encoding=UTF-8 

WITHIN

 <jvmArguments>
 -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8001
 -Dfile.encoding=UTF-8
 </jvmArguments>

Most of these packages are relying on the reflect package to make such things possible.

fmt.Sprintf() is using -> func (p *pp) printArg(arg interface{}, verb rune) of standard lib

Go to line 638 -> https://golang.org/src/fmt/print.go

Reflection:

https://golang.org/pkg/reflect/

Example code:

https://github.com/donutloop/toolkit/blob/master/debugutil/prettysprint.go

What is the return type of the round() method in the snippet?

If this is the Math.round() method, it returns a Long when the input param is Double.

So, you will have to cast the return value:

int a = (int) Math.round(doubleVar);

Allowed default size of URI is 8177 characters in GET request. Simple code in python for such testing.

#!/usr/bin/env python2

import sys
import socket

if __name__ == "__main__":
    string = sys.argv[1]
    buf_get = "x" * int(string)
    buf_size = 1024
    request = "HEAD %s HTTP/1.1\nHost:localhost\n\n" % buf_get
    print "===>", request

    sock_http = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock_http.connect(("localhost", 80))
    sock_http.send(request)
    while True:
       print "==>", sock_http.recv(buf_size)
       if not sock_http.recv(buf_size):
           break
    sock_http.close()

On 8178 characters you will get such message: HTTP/1.1 414 Request-URI Too Large

I had a similar but different problem and still unable to work when I use $('#myModal'). I was able to get it working when I use $(window).

My other problem is that I found that the show event would not fire if I stored my modal div html content in a javascript variable like.

var content="<div id='myModal' ...";
$(content).modal();
$(window).on('show.bs.modal', function (e) {
  alert('show test');
});

the event never fired because it didn't occur

my fix was to include the divs in the html body

<body>
    <div id='myModal'>
       ...
    </div>
    <script>
        $('#myModal).modal();
        $(window).on('show.bs.modal', function (e) {
            alert('show test');
        });
    </script>
</body>

Whenever you type cast integer to char it will return the ascii value of that int (once go through the ascii table for better understanding)

    int a=68;
    char b=(char)a;

    System.out.println(b);//it will return ascii value of 68

    //output- D

As David Olsson has said, you can use HTML in your string resources:

<resource>
    <string name="my_string">A string with <i>actual</i> <b>formatting</b>!</string>
</resources>

Then if you use getText(R.string.my_string) rather than getString(R.string.my_string) you get back a CharSequence rather than a String that contains the formatting embedded.

Sample to execute an SQL string within the stored procedure:

(I'm using this to compare the number of entries on each table as first check for a regression test, within a cursor loop)

select @SqlQuery1 = N'select @CountResult1 = (select isnull(count(*),0) from ' + @DatabaseFirst+'.dbo.'+@ObjectName + ')'

execute sp_executesql    @SqlQuery1 , N'@CountResult1 int OUTPUT',     @CountResult1 = @CountResult1 output;

Using the -e check will check for files and this includes directories.

if [ -e ${FILE_PATH_AND_NAME} ]
then
    echo "The file or directory exists."
fi

Eventually found the FontForge Windows installer package and opened the PDF through the installed program. Worked a treat, so happy.

We can't use "PHP in between JavaScript", because PHP runs on the server and JavaScript - on the client.

However we can generate JavaScript code as well as HTML, using all PHP features, including the escaping from HTML one.

But now you can do much more:

a = "cruel world"

a.scan(/\w+/)        #=> ["cruel", "world"]

a.scan(/.../)        #=> ["cru", "el ", "wor"]

a.scan(/(...)/)      #=> [["cru"], ["el "], ["wor"]]

a.scan(/(..)(..)/)   #=> [["cr", "ue"], ["l ", "wo"]]

Here is a simple one-line solution

((int) ((value + 0.005f) * 100)) / 100f

You mean, like this:

grep -o '.\{0,20\}test_pattern.\{0,20\}' file

?

That will print up to twenty characters on either side of test_pattern. The \{0,20\} notation is like *, but specifies zero to twenty repetitions instead of zero or more.The -o says to show only the match itself, rather than the entire line.

/test.html#alert('heello')

test.html
<button onClick="eval(document.location.hash.substring(1))">do it</button>

I deleted and re-installed the Android SDK Platform-Tools 23 23.0.0. This solved the problem. Yesterday i had done a complete update of the SDK using SDK Manager, deleting some parts that i believed i no longer needed and downloading updates. Perhaps this was the source of the problem.

Note: please see an alternative to git rebase -i in the comments below—

git reset --soft HEAD^

First, remove the commit on your local repository. You can do this using git rebase -i. For example, if it's your last commit, you can do git rebase -i HEAD~2 and delete the second line within the editor window that pops up.

Then, force push to GitHub by using git push origin +branchName --force

See Git Magic Chapter 5: Lessons of History - And Then Some for more information (i.e. if you want to remove older commits).

Oh, and if your working tree is dirty, you have to do a git stash first, and then a git stash apply after.

Try this in the .htaccess of the external root folder :

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

And if it only concerns .js scripts you should wrap the above code inside this:

<FilesMatch "\.(js)$">
...
</FilesMatch>

What is the real difference between one-to-many and many-to-one relationship?

There are conceptual differences between these terms that should help you visualize the data and also possible differences in the generated schema that should be fully understood. Mostly the difference is one of perspective though.

In a one-to-many relationship, the local table has one row that may be associated with many rows in another table. In the example from SQL for beginners, one Customer may be associated to many Orders.

In the opposite many-to-one relationship, the local table may have many rows that are associated with one row in another table. In our example, many Orders may be associated to one Customer. This conceptual difference is important for mental representation.

In addition, the schema which supports the relationship may be represented differently in the Customer and Order tables. For example, if the customer has columns id and name:

id,name
1,Bill Smith
2,Jim Kenshaw

Then for a Order to be associated with a Customer, many SQL implementations add to the Order table a column which stores the id of the associated Customer (in this schema customer_id:

id,date,amount,customer_id
10,20160620,12.34,1
11,20160620,7.58,1
12,20160621,158.01,2

In the above data rows, if we look at the customer_id id column, we see that Bill Smith (customer-id #1) has 2 orders associated with him: one for $12.34 and one for $7.58. Jim Kenshaw (customer-id #2) has only 1 order for $158.01.

What is important to realize is that typically the one-to-many relationship doesn't actually add any columns to the table that is the "one". The Customer has no extra columns which describe the relationship with Order. In fact the Customer might also have a one-to-many relationship with ShippingAddress and SalesCall tables and yet have no additional columns added to the Customer table.

However, for a many-to-one relationship to be described, often an id column is added to the "many" table which is a foreign-key to the "one" table -- in this case a customer_id column is added to the Order. To associated order #10 for $12.34 to Bill Smith, we assign the customer_id column to Bill Smith's id 1.

However, it is also possible for there to be another table that describes the Customer and Order relationship, so that no additional fields need to be added to the Order table. Instead of adding a customer_id field to the Order table, there could be Customer_Order table that contains keys for both the Customer and Order.

customer_id,order_id
1,10
1,11
2,12

In this case, the one-to-many and many-to-one is all conceptual since there are no schema changes between them. Which mechanism depends on your schema and SQL implementation.

Hope this helps.

First of all, you lack parentheses to call GetType. What you see is the MethodInfo describing the GetType method on [DayOfWeek]. To actually call GetType, you should do:

$a.GetType();
$b.GetType();

You should see that $a is a [DayOfWeek], and $b is a custom object generated by the Select-Object cmdlet to capture only the DayOfWeek property of a data object. Hence, it's an object with a DayOfWeek property only:

C:\> $b.DayOfWeek -eq $a
True

Its is a new line

The %pdb magic command is good to use as well. Just say %pdb on and subsequently the pdb debugger will run on all exceptions, no matter how deep in the call stack. Very handy.

If you have a particular line that you want to debug, just raise an exception there (often you already are!) or use the %debug magic command that other folks have been suggesting.

It looks like SyndFeed is not using generics.

You could either have an unsafe cast and a warning suppression:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = (List<SyndEntry>) sf.getEntries();

or call Collections.checkedList - although you'll still need to suppress the warning:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = Collections.checkedList(sf.getEntries(), SyndEntry.class);

Why nobody mentioned docker-compose! I 've just been using it for one week, and I cannot survive without it. All you need is writing a yml which takes only several minutes of studying, and then you are ready to go. It can boot images, containers (which are needed in so-called services) and let you review logs just like you use with docker native commands. Git it a try:

docker-compose up -d
docker-compose down --rmi 'local'

Before I used docker-compose, I wrote my own shell script, then I had to customize the script whenever needed especially when application architecture changed. Now I don't have to do this anymore, thanks to docker-compose.

try this code in here...this is done using javascript onKeyUp() function...

<script>
function toCount(entrance,exit,text,characters) {  
var entranceObj=document.getElementById(entrance);  
var exitObj=document.getElementById(exit);  
var length=characters - entranceObj.value.length;  
if(length <= 0) {  
length=0;  
text='<span class="disable"> '+text+' <\/span>';  
entranceObj.value=entranceObj.value.substr(0,characters);  
}  
exitObj.innerHTML = text.replace("{CHAR}",length);  
}

You can't inject content from another site (domain) using AJAX. The reason an iFrame is suited for these kinds of things is that you can specify the source to be from another domain.

All of the answers in this question helped me but I thought I'd add some additional information for posterity.

It turned out that I had a test dependency on gwt-test-utils which brought in the gwt-dev package. Unfortunately gwt-dev contains a full copy of Jetty, JSP, JSTL, etc. which was ahead of the proper packages on the classpath. So even though I had proper dependencies on the JSTL 1.2 it would loading the 1.0 version internal to gwt-dev. Grumble.

The solution for me was to not run with test scope so I don't pick up the gwt-test-utils package at runtime. Removing the gwt-dev package from the classpath in some other manner would also have fixed the problem.

Try:

rm -rf node_modules && npm install

Wiping node_modules first, often tends to fix a lot of weird, package related issues like that in Node.

Kindly find my answer it is in one line code:

#include <stdio.h> int main(void){ int c = 12388884; printf("length of integer is: %d",printf("%d",c)); return 0; }

that is simple and smart! Upvote if you like this!

Looks like most of the answers on this thread have not kept up. iOS Safari on iPads have fullscreen support now and it's very easy to implement using javascript.

Here's my full article on how to implement fullscreen capability on your web app.

You can write a for loop for this... %)

for x in *
do
        if [ "$x" != "exclude_criteria" ]
        then
                rm -f $x;
        fi
done;

If find and xarg versions on your system doesn't support -print0 and -0 switches (for example AIX find and xargs) you can use this terribly looking code:

 find . -name "*foo*" | sed -e "s/'/\\\'/g" -e 's/"/\\"/g' -e 's/ /\\ /g' | xargs cp /your/dest

Here sed will take care of escaping the spaces and quotes for xargs.

Tested on AIX 5.3

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

Either you can Downgrade to JRE 1.7.49

Step to fix:-

• Go to Lib folder of Liferay Tomcat .

• Replace :- ecj-3.7.2.jar with ecj-4.4.2.

• Restart the Server

I think this way should be faster; cause it doesn't split string and join it again; just using regex.

var str = text.replace(/(^\w{1})|(\s{1}\w{1})/g, match => match.toUpperCase());

Explanation:

1. (^\w{1}): match first char of string
2. |: or
3. (\s{1}\w{1}): match one char that came after one space
4. g: match all
5. match => match.toUpperCase(): replace with can take function, so; replace match with upper case match

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

Old topic, but never clearly answered. I've been working on similar as well, and found the solution:

The pipe (|) in this code sample from Austin isn't the delimiter, but to pipe the ForEach-Object, so if you want to use it as delimiter, you need to do this:

Import-Csv H:\Programs\scripts\SomeText.csv -delimiter "|" |`
ForEach-Object {
    $Name += $_.Name
    $Phone += $_."Phone Number"
}

Spent a good 15 minutes on this myself before I understood what was going on. Hope the answer helps the next person reading this avoid the wasted minutes! (Sorry for expanding on your comment Austin)

Under iterm2's Preferences > Profile > Keys, you click the + below Key Mappings and record a new shortcut. For Action, select Send Escape Sequence and type b or f for backwards and forwards respectively.

When I tried to record one for (Ctrl+?), I noticed in the Keyboard Shortcut field that the arrow never showed up. Turns out I had to disable the default mac's System Preferences > Keyboard > Shortcuts > Mission Control shorcuts first to get things to work, as they'll override iterm2's default shortcuts. Should be true for the standard terminal app, too.

For someone from internet, there was a similar question https://stackoverflow.com/a/35848666/906265 I do provide the modified answer from it here as well:

ruby -I. main.rb

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

If your numbers are always 4 digits long:

=RIGHT(A1,LEN(A1)-5) //'0001 Baseball' returns Baseball

If the numbers are variable (i.e. could be more or less than 4 digits) then:

=RIGHT(A1,LEN(A1)-FIND(" ",A1,1)) //'123456 Baseball’ returns Baseball

I would recommend using the commons-dbcp library. There are numerous examples listed on how to use it, here is the link to the move simple one. The usage is very simple:

 BasicDataSource ds = new BasicDataSource();
 ds.setDriverClassName("oracle.jdbc.driver.OracleDriver")
 ds.setUsername("scott");
 ds.setPassword("tiger");
 ds.setUrl(connectURI);
 ...
 Connection conn = ds.getConnection();

You only need to create the data source once, so make sure you read the documentation if you do not know how to do that. If you are not aware of how to properly write JDBC statements so you do not leak resources, you also might want to read this Wikipedia page.

You can even extend the file module and even set the owner,group & permission through it. (Ref: Ansible file documentation)

- name: Creates directory
  file:
    path: /src/www
    state: directory
    owner: www-data
    group: www-data
    mode: 0775

Even, you can create the directories recursively:

- name: Creates directory
  file:

This way, it will create both directories, if they didn't exist.

I think this post by Jeff Attwood addresses your question perfectly. It takes you through the differences between newlines on Dos, Mac and Unix, and then explains the history of CR (Carriage return) and LF (Line feed).

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

you would call the function like this:

add(3,5)

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

Which would set the variable answer equal to 11 in this case.

Here's a subquery for you!

List<int> IdsToFind = new List<int>() {2, 3, 4};

db.Users
.Where(u => SqlMethods.Like(u.LastName, "%fra%"))
.Where(u =>
    db.CompanyRolesToUsers
    .Where(crtu => IdsToFind.Contains(crtu.CompanyRoleId))
    .Select(crtu =>  crtu.UserId)
    .Contains(u.Id)
)

Regarding this portion of the question:

predicateAnd = predicateAnd.And(c => c.LastName.Contains(
                                TextBoxLastName.Text.Trim()));

I strongly recommend extracting the string from the textbox before authoring the query.

string searchString = TextBoxLastName.Text.Trim();
predicateAnd = predicateAnd.And(c => c.LastName.Contains( searchString));

You want to maintain good control over what gets sent to the database. In the original code, one possible reading is that an untrimmed string gets sent into the database for trimming - which is not good work for the database to be doing.

Been struggling with this for the past days and found a solution that works really well. The soft keyboard is hidden when a touch is done anywhere outside the EditText.

Code posted here: hide default keyboard on click in android

I've had the same problem using Android Studio and managed to get around by selecting No Filters in the select box in the top right corner of LogCat. By doing this I started receiving everything Android logs in the background into LogCat including my missing Log calls.

Because ... it (MILLISECONDS) is a static field (hiding in an enumeration, but that's what it is) ... however it is being invoked upon an instance of the given type (but see below as this isn't really true¹).

javac will "accept" that, but it should really be MyUnits.MILLISECONDS (or non-prefixed in the applicable scope).

¹ Actually, javac "rewrites" the code to the preferred form -- if m happened to be null it would not throw an NPE at run-time -- it is never actually invoked upon the instance).

Happy coding.

I'm not really seeing how the question title fits in with the rest :-) More accurate and specialized titles increase the likely hood the question/answers can benefit other programmers.

(Make sure to install react-router using npm!)

To use react-router, you do the following:

1. Create a file with routes defined using Route, IndexRoute components

2. Inject the Router (with 'r'!) component as the top-level component for your app, passing the routes defined in the routes file and a type of history (hashHistory, browserHistory)

3. Add {this.props.children} to make sure new pages will be rendered there
4. Use the Link component to change pages

Step 1 routes.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

/**
 * Import all page components here
 */
import App from './components/App';
import MainPage from './components/MainPage';
import SomePage from './components/SomePage';
import SomeOtherPage from './components/SomeOtherPage';

/**
 * All routes go here.
 * Don't forget to import the components above after adding new route.
 */
export default (
  <Route path="/" component={App}>
    <IndexRoute component={MainPage} />
    <Route path="/some/where" component={SomePage} />
    <Route path="/some/otherpage" component={SomeOtherPage} />
  </Route>
);

Step 2 entry point (where you do your DOM injection)

// You can choose your kind of history here (e.g. browserHistory)
import { Router, hashHistory as history } from 'react-router';
// Your routes.js file
import routes from './routes';

ReactDOM.render(
  <Router routes={routes} history={history} />,
  document.getElementById('your-app')
);

Step 3 The App component (props.children)

In the render for your App component, add {this.props.children}:

render() {
  return (
    <div>
      <header>
        This is my website!
      </header>

      <main>
        {this.props.children}
      </main>

      <footer>
        Your copyright message
      </footer>
    </div>
  );
}

Step 4 Use Link for navigation

Anywhere in your component render function's return JSX value, use the Link component:

import { Link } from 'react-router';
(...)
<Link to="/some/where">Click me</Link>

Use overflow-y:auto for displaying scroll automatically when the content exceeds the divs set height.

See this demo

One issue which doesn't seem to have been mentioned is that this error can crop up due to a problem with the code that has nothing to do with indentation.

For example, take the following script:

def add_one(x):
    try:
        return x + 1
add_one(5)

This returns an IndentationError: unexpected unindent when the problem is of course a missing except: statement.

My point: check the code above where the unexpected (un)indent is reported!

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.

After many years of success with the answers above, I have found this not to work again - but I did find a working solution for subplots at

https://jdhao.github.io/2017/06/03/change-aspect-ratio-in-mpl

With full credit of course to the author above (who can perhaps rather post here), the relevant lines are:

ratio = 1.0
xleft, xright = ax.get_xlim()
ybottom, ytop = ax.get_ylim()
ax.set_aspect(abs((xright-xleft)/(ybottom-ytop))*ratio)

The link also has a crystal clear explanation of the different coordinate systems used by matplotlib.

Thanks for all great answers received - especially @Yann's which will remain the winner.

In my case, I have double-clicked a Visual 2013 sln file and Visual 2012 opened (instead of Visual 2013). Trying to compile with Visual 2012, a project that has the Platform Toolset set to "v120" showed the error above mentioned. However, reopening the sln with Visual 2013, the Platform Toolset was set to "Visual Studio 2013 (v120)" - please note the complete name this time -, actually did the job for me. The project compiles well now.

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

It will depend on what are you plotting.

import matplotlib.pyplot as plt

 x=['long_text_for_a_label_a',
    'long_text_for_a_label_b',
    'long_text_for_a_label_c']
y=[1,2,3]
myplot = plt.plot(x,y)
for item in myplot.axes.get_xticklabels():
    item.set_rotation(90)

For pandas and seaborn that give you an Axes object:

df = pd.DataFrame(x,y)
#pandas
myplot = df.plot.bar()
#seaborn 
myplotsns =sns.barplot(y='0',  x=df.index, data=df)
# you can get xticklabels without .axes cause the object are already a 
# isntance of it
for item in myplot.get_xticklabels():
    item.set_rotation(90)

If you need to rotate labels you may need change the font size too, you can use font_scale=1.0 to do that.

XSD:
XSD (XML Schema Definition) specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
Xml:
XML was designed to describe data.It is independent from software as well as hardware.
It enhances the following things.
-Data sharing.
-Platform independent.
-Increasing the availability of Data.

Differences:

1. XSD is based and written on XML.

2. XSD defines elements and structures that can appear in the document, while XML does not.

3. XSD ensures that the data is properly interpreted, while XML does not.

4. An XSD document is validated as XML, but the opposite may not always be true.

5. XSD is better at catching errors than XML.

An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.
for eg:
A date that is expressed as 1/12/2010 can either mean January 12 or December 1st. Declaring a date data type in an XSD document, ensures that it follows the format dictated by XSD.

The NetBeans documentation merely states a hierarchy for FileEncodingQuery (FEQ), suggesting that you can set encoding on a per-file basis:

• NetBeans wiki article "DevFaqI18nFileEncodingQueryObject": Project Encoding vs. File Encoding - What are the precedence rules used in NetBeans 6.x?

Just for reference, this is the wiki-page regarding project-wide settings:

• NetBeans wiki article "FaqI18nProjectEncoding": How do I set or modify the character encoding for a project?

If none of the above is working, you are probably working on EDI trasaction where you need to validate your result against an HIPPA schema or any other complex xsd for that matter. The requirement is that, say there 8 REF segments and any of them have to appear in any order and also not all are required, means to say you may have them in following order 1st REF, 3rd REF , 2nd REF, 9th REF. Under default situation EDI receive will fail, beacause default complex type is

<xs:sequence>
  <xs:element.../>
</xs:sequence>

The situation is even complex when you are calling your element by refrence and then that element in its original spot is quite complex itself. for example:

<xs:element>
<xs:complexType>
<xs:sequence>
<element name="REF1"  ref= "REF1_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF2"  ref= "REF2_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF3"  ref= "REF3_Mycustomelment" minOccurs="0" maxOccurs="1">
</xs:sequence>
</xs:complexType>
</xs:element>

Solution:

Here simply replacing "sequence" with "all" or using "choice" with min/max combinations won't work!

First thing replace "xs:sequence" with "<xs:all>" Now,You need to make some changes where you are Referring the element from, There go to:

<xs:annotation>
  <xs:appinfo>
    <b:recordinfo structure="delimited" field.........Biztalk/2003">

***Now in the above segment add trigger point in the end like this trigger_field="REF01_...complete name.." trigger_value = "38" Do the same for other REF segments where trigger value will be different like say "18", "XX" , "YY" etc..so that your record info now looks like:b:recordinfo structure="delimited" field.........Biztalk/2003" trigger_field="REF01_...complete name.." trigger_value="38">

This will make each element unique, reason being All REF segements (above example) have same structure like REF01, REF02, REF03. And during validation the structure validation is ok but it doesn't let the values repeat because it tries to look for remaining values in first REF itself. Adding triggers will make them all unique and they will pass in any order and situational cases (like use 5 out 9 and not all 9/9).

Hope it helps you, for I spent almost 20 hrs on this.

Good Luck

As the file object reads the file, it uses a pointer to keep track of where it is. If you read part of the file, then go back to it later it will pick up where you left off. If you read the whole file, and go back to the same file object, it will be like reading an empty file because the pointer is at the end of the file and there is nothing left to read. You can use file.tell() to see where in the file the pointer is and file.seek to set the pointer. For example:

>>> file = open('myfile.txt')
>>> file.tell()
0
>>> file.readline()
'one\n'
>>> file.tell()
4L
>>> file.readline()
'2\n'
>>> file.tell()
6L
>>> file.seek(4)
>>> file.readline()
'2\n'

Also, you should know that file.readlines() reads the whole file and stores it as a list. That's useful to know because you can replace:

for line in file.readlines():
    #do stuff
file.seek(0)
for line in file.readlines():
    #do more stuff

with:

lines = file.readlines()
for each_line in lines:
    #do stuff
for each_line in lines:
    #do more stuff

You can also iterate over a file, one line at a time, without holding the whole file in memory (this can be very useful for very large files) by doing:

for line in file:
    #do stuff

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

To get this to work I had to combine many of the above answers, to anyone who this might help here is my much simpler process.

If you have Windows 10 just start typing "edit environmental..." and it'll pop up right away. Click path and Edit… then paste the ;C:\Program Files\Git\bin\git.exe;C:\Program Files\Git\cmd at the end of the path already there, don't forget the ; to separate your new github path from the current path.

You do not need the guid but if you want to know how to find it open bash, type git --man-path

I don't think Ansible provides this feature, which it should. Here's something that you can do:

hosts: "{{ variable_host | default('web') }}"

and you can pass variable_host from either command-line or from a vars file, e.g.:

ansible-playbook server.yml --extra-vars "variable_host=newtarget(s)"

Node has its own built in GUI debugger as of version 6.3 (using Chrome's DevTools)

Simply pass the inspector flag and you'll be provided with a URL to the inspector:

node --inspect server.js

You can also break on the first line by passing --inspect-brk instead.

The default value is indeed false.

However you can't use a local variable is it's not been assigned first.

You can use the default keyword to verify:

bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }

Try this, you will know the difference between change and modify,

ALTER TABLE table_name CHANGE curr_column_name new_column_name new_column_datatype [constraints]

ALTER TABLE table_name MODIFY column_name new_column_datatype [constraints]

• You can change name and datatype of the particular column using CHANGE.
• You can modify the particular column datatype using MODIFY. You cannot change the name of the column using this statement.

Hope, I explained well in detail.

In Python 2, raw_input() returns a string, and input() tries to run the input as a Python expression.

Since getting a string was almost always what you wanted, Python 3 does that with input(). As Sven says, if you ever want the old behaviour, eval(input()) works.

I know this is tagged html/css only, but you can't do that with css only. Easiest way will be using some jQuery.

var fixmeTop = $('.fixme').offset().top;       // get initial position of the element

$(window).scroll(function() {                  // assign scroll event listener

    var currentScroll = $(window).scrollTop(); // get current position

    if (currentScroll >= fixmeTop) {           // apply position: fixed if you
        $('.fixme').css({                      // scroll to that element or below it
            position: 'fixed',
            top: '0',
            left: '0'
        });
    } else {                                   // apply position: static
        $('.fixme').css({                      // if you scroll above it
            position: 'static'
        });
    }

});

Try this command:

find / -name file.look

In the Coursera course, an Introduction to R Programming, this skill was tested. They gave all the students 332 separate csv files and asked them to programmatically combined several of the files to calculate the mean value of the pollutant.

This was my solution:

  # create your empty dataframe so you can append to it.
  combined_df <- data.frame(Date=as.Date(character()),
                    Sulfate=double(),
                    Nitrate=double(),
                    ID=integer())
  # for loop for the range of documents to combine
  for(i in min(id): max(id)) {
    # using sprintf to add on leading zeros as the file names had leading zeros
    read <- read.csv(paste(getwd(),"/",directory, "/",sprintf("%03d", i),".csv", sep=""))
    # in your loop, add the files that you read to the combined_df
    combined_df <- rbind(combined_df, read)
  }

Try absolute positioning:

<div style="position:relative;width:100%;">
    <div id="help" style="
    position:absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    z-index:1;">
        <img src="/portfolio/space_1_header.png" border="0" style="width:100%;">
    </div>
</div>

Just to present an alternative way to fix this problem (if you don't really care about supporting IE):

A soft coded solution would be to use display: table (no support in IE7) along with table-layout: fixed (to ensure equal width columns).

In case you cannot change the declaration for whatever reason, you can do:

Out of curiosity, I found a box with a GNU version of sed (v4.1.5) and tested the (uncached) performance of two approaches suggested so far, using an 11M line text file:

$ wc -l input
11771722 input

$ time head -1000 input > output; time tail -n +1000 input > input.tmp; time cp input.tmp input; time rm input.tmp

For this test, at least, it looks like sed is slower than the tail approach (27 sec vs ~14 sec).

Adding to other answers already given above. If case insensivity is of any importance to you, then use Jackson. Gson does not support case insensitivity for key names, while jackson does.

for deleting Empty folders

i wanted to delete an empty directory(folder) i created, git can not delete it, after some research i learned Git doesn't track empty directories. If you have an empty directory in your working tree you should simply removed it with

rm -r folderName

There is no need to involve Git.

You're calling writer.close(); after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.

public void writeToFile(){
    String file_text= pedStatusText + "     " + gatesStatus + "     " + DrawBridgeStatusText;
    try {
        writer.write(file_text);
        writer.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

And add a method cleanUp to close the stream.

public void cleanUp() {
     writer.close();
}

This means that you have the responsibility to make sure that you're calling cleanUp when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.

EDIT: You can create a new stream each time you want to write to the file, by moving writer into the writeToFile() method..

 public void writeToFile() {
    FileWriter writer = new FileWriter("status.txt", true);
    // ... Write to the file.

    writer.close();
 }

I have been trying to add environment variables. My goal was to store some user information to system variables such that I can use those variables for future solutions, as an alternative to config files. However, the method described in the code below did not help me at all.

import os
os.environ["variable_1"] = "value_1"
os.environ["variable_2"] = "value_2"
# To Verify above code
os.environ.get("variable_1")
os.environ.get("variable_2")

This simple code block works well, however, these variables exist inside the respective processes such that you will not find them in the environment variables tab of windows system settings. Pretty much above code did not serve my purpose. This problem is discussed here: variable save problem

os.environ.putenv(key, value)

Another unsuccessful attempt. So, finally, I managed to save variable successfully inside the window environment register by mimicking the windows shell commands wrapped inside the system class of os package. The following code describes this successful attempt.

os.system("SETX {0} {1} /M".format(key, value))

I hope this will be helpful for some of you.

re.sub is definitely what you are looking for. And so you know, you don't need the anchors and the wildcards.

re.sub(r"(?i)interfaceOpDataFile", "interfaceOpDataFile %s" % filein, line)

will do the same thing--matching the first substring that looks like "interfaceOpDataFile" and replacing it.

I prefer a popup.

$shell = new-object -comobject "WScript.Shell"

If $choice equals 6, the answer was Yes If $choice equals 7, the answer was No

I have heard this argument too - from people who forgot to put an index on their foreign keys and then complained that certain operations were slow (because constraint checking could take advantage of any index). So to sum up: There is no good reason not to use foreign keys. All modern databases support cascaded deletes, so...

For those scripting tmux, there is a command called rename-window so e.g.

tmux rename-window -t <window> <newname>

As suggested by others this happens due to service client mismatch.

I ran into the same problem, when was debugging got to know that there is a mismatch in the binding. Instead of WSHTTPBinding I was referring to BasicHttpBinding. In my case I am referring both BasicHttp and WsHttp. I was dynamically assigning the binding based on the reference. So check your service constructor as shown below

You can do summary(santa$Believe) and you will get the count for TRUE and FALSE

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

root.mainloop()

I would say that a scrollBottom as a direct opposite of scrollTop should be:

var scrollBottom = $(document).height() - $(window).height() - $(window).scrollTop();

Here is a small ugly test that works for me:

// SCROLLTESTER START //
$('<h1 id="st" style="position: fixed; right: 25px; bottom: 25px;"></h1>').insertAfter('body');

$(window).scroll(function () {
  var st = $(window).scrollTop();
  var scrollBottom = $(document).height() - $(window).height() - $(window).scrollTop();

  $('#st').replaceWith('<h1 id="st" style="position: fixed; right: 25px; bottom: 25px;">scrollTop: ' + st + '<br>scrollBottom: ' + scrollBottom + '</h1>');
});
// SCROLLTESTER END //

Your assignment has an extra $:

export PATH=$PATH:${PWD}:/foo/bar

You can tell Git what to do with your index (set of files that will become the next commit) and working directory when performing git reset by using one of the parameters:

--soft: Only commits will be reseted, while Index and the working directory are not altered.

--mixed: This will reset the index to match the HEAD, while working directory will not be touched. All the changes will stay in the working directory and appear as modified.

--hard: It resets everything (commits, index, working directory) to match the HEAD.

In your case, I would use git reset --soft to keep your modified changes in Index and working directory. Be sure to check this out for a more detailed explanation.

SELECT height/10.0 AS HeightDecimal FROM dbo.whatever;

If you want a specific precision scale, then say so:

SELECT CONVERT(DECIMAL(16,4), height/10.0) AS HeightDecimal
  FROM dbo.whatever;

Now you can use nameof:

public static void Output<T>(IEnumerable<T> dataSource) where T : class
{
    string dataSourceName = typeof(T).Name;
    switch (dataSourceName)
    {
        case nameof(CustomerDetails):
            var t = 123;
            break;
        default:
            Console.WriteLine("Test");
    }
}

nameof(CustomerDetails) is basically identical to the string literal "CustomerDetails", but with a compile-time check that it refers to some symbol (to prevent a typo).

nameof appeared in C# 6.0, so after this question was asked.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

@Joao Marcos solution works for me but I had to modify the code to make it work on IE, below if what the code looks like

       downloadFile(url,filename) {
        var that = this;
        const extension =  url.split('/').pop().split('?')[0].split('.').pop();

        var req = new XMLHttpRequest();
        req.open("GET", url, true);
        req.responseType = "blob";
        req.onload = function (event) {
            const fileName = `${filename}.${extension}`;
            const blob = req.response;

            if (window.navigator.msSaveBlob) { // IE
                window.navigator.msSaveOrOpenBlob(blob, fileName);
            } 
            const link = document.createElement('a');
            link.href = window.URL.createObjectURL(blob);                
            link.download = fileName;
            link.click();
            URL.revokeObjectURL(link.href);

        };

        req.send();
    },

When you loop in an array like you did, your for variable(in this example i) is current element of your array.

For example if your ar is [1,5,10], the i value in each iteration is 1, 5, and 10. And because your array length is 3, the maximum index you can use is 2. so when i = 5 you get IndexError. You should change your code into something like this:

for i in ar:
    theSum = theSum + i

Or if you want to use indexes, you should create a range from 0 ro array length - 1.

for i in range(len(ar)):
    theSum = theSum + ar[i]

You don't even have to set a specific width for the cells, table-layout: fixed suffices to spread the cells evenly.

ul {_x000D_
    width: 100%;_x000D_
    display: table;_x000D_
    table-layout: fixed;_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
    display: table-cell;_x000D_
    text-align: center;_x000D_
    border: 1px solid hotpink;_x000D_
    vertical-align: middle;_x000D_
    word-wrap: break-word;_x000D_
}

<ul>_x000D_
  <li>foo<br>foo</li>_x000D_
  <li>barbarbarbarbar</li>_x000D_
  <li>baz</li>_x000D_
</ul>

Note that for table-layout to work the table styled element must have a width set (100% in my example).

Always check with your business domain expert. If that's you, look for an industry standard. If, for example, the domain in question is a natural person's family name (surname) then for a UK business I'd go to the UK Govtalk data standards catalogue for person information and discover that a family name will be between 1 and 35 characters.

if you already deployed the code or can't change any configuration, you could remove all temp files from wsdl:

rm /tmp/wsdl-*

Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other. -- http://docs.angularjs.org/api/ng.directive:ngApp

As usual, create an SSH key and paste the public key to GitHub. Add the private key to ssh-agent. (I assume this is what you have done.)

To check everything is correct, use ssh -T [email protected]

Next, don't forget to modify the remote point as follows:

git remote set-url origin [email protected]:username/your-repository.git

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

In Kotlin you can create extension property:

inline var TextView.underline: Boolean
    set(visible) {
        paintFlags = if (visible) paintFlags or Paint.UNDERLINE_TEXT_FLAG
        else paintFlags and Paint.UNDERLINE_TEXT_FLAG.inv()
    }
    get() = paintFlags and Paint.UNDERLINE_TEXT_FLAG == Paint.UNDERLINE_TEXT_FLAG

And use:

textView.underline = true

Here are instructions for users with the newer Python 3.5 (Google brought me here, I suspect other 3.5 users might end up here as well):

I just successfully installed Pygame 1.9.2a0-cp35 on Windows and it runs with Python 3.5.1.

• Install Python, and remember the install location
• Go here and download pygame-1.9.2a0-cp35-none-win32.whl
• Move the downloaded .whl file to your python35/Scripts directory
• Open a command prompt in the Scripts directory (Shift-Right click in the directory > Open a command window here)

• Enter the command:

  pip3 install pygame-1.9.2a0-cp35-none-win32.whl

• If you get an error in the last step, try:

  python -m pip install pygame-1.9.2a0-cp35-none-win32.whl

And that should do it. Tested as working on Windows 10 64bit.

Try this:

textView.setTextColor(getResources().getColor(R.color.errorColor, null));

Returns numeric rows

I found the solution with following query and works for me:

SELECT * FROM myTable WHERE col1 > 0;

This query return rows having only greater than zero number column that col1

Returns non numeric rows

if you want to check column not numeric try this one with the trick (!col1 > 0):

SELECT * FROM myTable WHERE !col1 > 0;

I believe referencing this.state inside of setState() is discouraged (State Updates May Be Asynchronous).

The docs recommend using setState() with a callback function so that prevState is passed in at runtime when the update occurs. So this is how it would look:

Using Array.prototype.filter without ES6

removeItem : function(index) {
  this.setState(function(prevState){
    return { data : prevState.data.filter(function(val, i) {
      return i !== index;
    })};
  });
}

Using Array.prototype.filter with ES6 Arrow Functions

removeItem(index) {
  this.setState((prevState) => ({
    data: prevState.data.filter((_, i) => i !== index)
  }));
}

Using immutability-helper

import update from 'immutability-helper'
...
removeItem(index) {
  this.setState((prevState) => ({
    data: update(prevState.data, {$splice: [[index, 1]]})
  }))
}

Using Spread

function removeItem(index) {
  this.setState((prevState) => ({
    data: [...prevState.data.slice(0,index), ...prevState.data.slice(index+1)]
  }))
}

Note that in each instance, regardless of the technique used, this.setState() is passed a callback, not an object reference to the old this.state;

I liked Mithun's code, but I tweaked it a bit to make it give more reasonable answers.

Here is the Complete solution

#First Datasource (DB1)
db1.datasource.url: url
db1.datasource.username:user
db1.datasource.password:password

#Second Datasource (DB2)
db2.datasource.url:url
db2.datasource.username:user
db2.datasource.password:password

Since we are going to get access two different databases (db1, db2), we need to configure each data source configuration separately like:

public class DB1_DataSource {
@Autowired
private Environment env;
@Bean
@Primary
public LocalContainerEntityManagerFactoryBean db1EntityManager() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(db1Datasource());
    em.setPersistenceUnitName("db1EntityManager");
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<string, object=""> properties = new HashMap<>();
    properties.put("hibernate.dialect",
            env.getProperty("hibernate.dialect"));
    properties.put("hibernate.show-sql",
            env.getProperty("jdbc.show-sql"));
    em.setJpaPropertyMap(properties);
    return em;
}

@Primary
@Bean
public DataSource db1Datasource() {

    DriverManagerDataSource dataSource
            = new DriverManagerDataSource();
    dataSource.setDriverClassName(
            env.getProperty("jdbc.driver-class-name"));
    dataSource.setUrl(env.getProperty("db1.datasource.url"));
    dataSource.setUsername(env.getProperty("db1.datasource.username"));
    dataSource.setPassword(env.getProperty("db1.datasource.password"));

    return dataSource;
}

@Primary
@Bean
public PlatformTransactionManager db1TransactionManager() {

    JpaTransactionManager transactionManager
            = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(
            db1EntityManager().getObject());
    return transactionManager;
}
}

Second Datasource :

public class DB2_DataSource {

@Autowired
private Environment env;

@Bean
public LocalContainerEntityManagerFactoryBean db2EntityManager() {
    LocalContainerEntityManagerFactoryBean em
            = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(db2Datasource());
    em.setPersistenceUnitName("db2EntityManager");
    HibernateJpaVendorAdapter vendorAdapter
            = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<string, object=""> properties = new HashMap<>();
    properties.put("hibernate.dialect",
            env.getProperty("hibernate.dialect"));
    properties.put("hibernate.show-sql",
            env.getProperty("jdbc.show-sql"));
    em.setJpaPropertyMap(properties);
    return em;
}

@Bean
public DataSource db2Datasource() {
    DriverManagerDataSource dataSource
            = new DriverManagerDataSource();
    dataSource.setDriverClassName(
            env.getProperty("jdbc.driver-class-name"));
    dataSource.setUrl(env.getProperty("db2.datasource.url"));
    dataSource.setUsername(env.getProperty("db2.datasource.username"));
    dataSource.setPassword(env.getProperty("db2.datasource.password"));

    return dataSource;
}

@Bean
public PlatformTransactionManager db2TransactionManager() {
    JpaTransactionManager transactionManager
            = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(
            db2EntityManager().getObject());
    return transactionManager;
}
}

Here you can find the complete Example on my blog : Spring Boot with Multiple DataSource Configuration

You can use error_log to send to your servers error log file (or an optional other file if you'd like)

In the absense of cache control directives that specify otherwise, a 301 redirect defaults to being cached without any expiry date.

That is, it will remain cached for as long as the browser's cache can accommodate it. It will be removed from the cache if you manually clear the cache, or if the cache entries are purged to make room for new ones.

You can verify this at least in Firefox by going to about:cache and finding it under disk cache. It works this way in other browsers including Chrome and the Chromium based Edge, though they don't have an about:cache for inspecting the cache.

In all browsers it is still possible to override this default behavior using caching directives, as described below:

If you don't want the redirect to be cached

This indefinite caching is only the default caching by these browsers in the absence of headers that specify otherwise. The logic is that you are specifying a "permanent" redirect and not giving them any other caching instructions, so they'll treat it as if you wanted it indefinitely cached.

The browsers still honor the Cache-Control and Expires headers like with any other response, if they are specified.

You can add headers such as Cache-Control: max-age=3600 or Expires: Thu, 01 Dec 2014 16:00:00 GMT to your 301 redirects. You could even add Cache-Control: no-cache so it won't be cached permanently by the browser or Cache-Control: no-store so it can't even be stored in temporary storage by the browser.

Though, if you don't want your redirect to be permanent, it may be a better option to use a 302 or 307 redirect. Issuing a 301 redirect but marking it as non-cacheable is going against the spirit of what a 301 redirect is for, even though it is technically valid. YMMV, and you may find edge cases where it makes sense for a "permanent" redirect to have a time limit. Note that 302 and 307 redirects aren't cached by default by browsers.

If you previously issued a 301 redirect but want to un-do that

If people still have the cached 301 redirect in their browser they will continue to be taken to the target page regardless of whether the source page still has the redirect in place. Your options for fixing this include:

• A simple solution is to issue another redirect back again.

  If the browser is directed back to a same URL a second time during a redirect, it should fetch it from the origin again instead of redirecting again from cache, in an attempt to avoid a redirect loop. Comments on this answer indicate this now works in all major browsers - but there may be some minor browsers where it doesn't.

• If you don't have control over the site where the previous redirect target went to, then you are out of luck. Try and beg the site owner to redirect back to you.

Prevention is better than cure - avoid a 301 redirect if you are not sure you want to permanently de-commission the old URL.

This error will also occur when using pdsh to hosts which are not contained in your "known_hosts" file.

I was able to correct this by SSH'ing into each host manually and accepting the question "Do you want to add this to known hosts".

But how do I run this? I tried typing: sudo chkconfig.install which doesn't work.

I'm not sure where you got this package or what it contains; A url of download would be helpful. Without being able to look at the contents of chkconfig.install; I'm surprised to find a unix tool like chkconfig to be bundled in a zip archive, maybe it is still yet to be uncompressed, a tar.gz? but maybe it is a shell script?

I should suggest editing it and seeing what you are executing.

sh chkconfig.install or ./chkconfig.install ; which might work....but my suggestion would be to learn to use update-rc.d as the other answers have suggested but do not speak directly to the question...which is pretty hard to answer without being able to look at the data yourself.

The existing answers had a few problems for me:

1. I needed to insert text (e.g. 'Good Day John Doe') with html formatting where you would normally type your message.
2. At least on my machine, Outlook adds 2 blank lines above the signature where you should start typing. These should obviously be removed (replaced with custom HTML).

The code below does the job. Please note the following:

1. The 'From' parameter allows you to choose the account (since there could be different default signatures for different email accounts)
2. The 'Recipients' parameter expects an array of emails, and it will 'Resolve' the added email (i.e. find it in contacts, as if you had typed it in the 'To' box)
3. Late binding is used, so no references are required

'Opens an outlook email with the provided email body and default signature
'Parameters:
'  from: Email address of Account to send from.  Wildcards are supported e.g. *@example.com
'  recipients: Array of recipients.  Recipient can be a Contact name or email address
'  subject: Email subject

        'Ensure we are sending with the correct account (to insert the correct signature)

        .htmlBody = Replace(.htmlBody, "<o:p>&nbsp;</o:p>", "")
        'Insert the html at the start of the 'body' tag
        Dim bodyTagEnd As Long: bodyTagEnd = InStr(InStr(1, .htmlBody, "<body"), .htmlBody, ">")
        .htmlBody = Left(.htmlBody, bodyTagEnd) & htmlBody & Right(.htmlBody, Len(.htmlBody) - bodyTagEnd)
    End With
    Set oApp = Nothing
End Sub

Use as follows:

CreateMail from:="*@contoso.com", _
    recipients:= Array("[email protected]", "Jane Doe", "[email protected]"), _
    subject:= "Test Email", _
    htmlBody:= "<p>Good Day All</p><p>Hello <b>World!</b></p>"

Result:

if you getting this type of error so I suggest you used to stored proc data as usual list then binding the other controls because I also get this error so I solved it like this ex:-

repeater.DataSource = data.SPBinsReport().Tolist();
repeater.DataBind();

try like this

//Write a javascript method to bind click event of each "li" item

    function BindClickEvent()
    {
    var selector = '.nav li';
    //Removes click event of each li
    $(selector ).unbind('click');
    //Add click event
    $(selector ).bind('click', function()
    {
        $(selector).removeClass('active');
        $(this).addClass('active');
    });

    }

//first call this method when first time when page load

    $( document ).ready(function() {
         BindClickEvent();
    });

//Call BindClickEvent method from server side

    protected void Page_Load(object sender, EventArgs e)
    {
        ScriptManager.RegisterStartupScript(Page,GetType(), Guid.NewGuid().ToString(),"BindClickEvent();",true);
    }

In this context, I suppose it could be interpreted as

do
...
while cmd  != 'e' 

Given three tasks - FeedCat(), SellHouse() and BuyCar(), there are two interesting cases: either they all complete synchronously (for some reason, perhaps caching or an error), or they don't.

Let's say we have, from the question:

Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();
    // what here?
}

Now, a simple approach would be:

Task.WhenAll(x, y, z);

but ... that isn't convenient for processing the results; we'd typically want to await that:

async Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    await Task.WhenAll(x, y, z);
    // presumably we want to do something with the results...
    return DoWhatever(x.Result, y.Result, z.Result);
}

but this does lots of overhead and allocates various arrays (including the params Task[] array) and lists (internally). It works, but it isn't great IMO. In many ways it is simpler to use an async operation and just await each in turn:

async Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    // do something with the results...
    return DoWhatever(await x, await y, await z);
}

Contrary to some of the comments above, using await instead of Task.WhenAll makes no difference to how the tasks run (concurrently, sequentially, etc). At the highest level, Task.WhenAll predates good compiler support for async/await, and was useful when those things didn't exist. It is also useful when you have an arbitrary array of tasks, rather than 3 discreet tasks.

But: we still have the problem that async/await generates a lot of compiler noise for the continuation. If it is likely that the tasks might actually complete synchronously, then we can optimize this by building in a synchronous path with an asynchronous fallback:

Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    if(x.Status == TaskStatus.RanToCompletion &&
       y.Status == TaskStatus.RanToCompletion &&
       z.Status == TaskStatus.RanToCompletion)
        return Task.FromResult(
          DoWhatever(a.Result, b.Result, c.Result));
       // we can safely access .Result, as they are known
       // to be ran-to-completion

    return Awaited(x, y, z);
}

async Task Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
    return DoWhatever(await x, await y, await z);
}

This "sync path with async fallback" approach is increasingly common especially in high performance code where synchronous completions are relatively frequent. Note it won't help at all if the completion is always genuinely asynchronous.

Additional things that apply here:

1. with recent C#, a common pattern is for the async fallback method is commonly implemented as a local function:

   Task<string> DoTheThings() {
       async Task<string> Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
           return DoWhatever(await a, await b, await c);
       }
       Task<Cat> x = FeedCat();
       Task<House> y = SellHouse();
       Task<Tesla> z = BuyCar();
   
       if(x.Status == TaskStatus.RanToCompletion &&
          y.Status == TaskStatus.RanToCompletion &&
          z.Status == TaskStatus.RanToCompletion)
           return Task.FromResult(
             DoWhatever(a.Result, b.Result, c.Result));
          // we can safely access .Result, as they are known
          // to be ran-to-completion
   
       return Awaited(x, y, z);
   }
   

2. prefer ValueTask<T> to Task<T> if there is a good chance of things ever completely synchronously with many different return values:

   ValueTask<string> DoTheThings() {
       async ValueTask<string> Awaited(ValueTask<Cat> a, Task<House> b, Task<Tesla> c) {
           return DoWhatever(await a, await b, await c);
       }
       ValueTask<Cat> x = FeedCat();
       ValueTask<House> y = SellHouse();
       ValueTask<Tesla> z = BuyCar();
   
       if(x.IsCompletedSuccessfully &&
          y.IsCompletedSuccessfully &&
          z.IsCompletedSuccessfully)
           return new ValueTask<string>(
             DoWhatever(a.Result, b.Result, c.Result));
          // we can safely access .Result, as they are known
          // to be ran-to-completion
   
       return Awaited(x, y, z);
   }
   

3. if possible, prefer IsCompletedSuccessfully to Status == TaskStatus.RanToCompletion; this now exists in .NET Core for Task, and everywhere for ValueTask<T>

Read this for detail :

// 1 define a function pointer and initialize to NULL

int (TMyClass::*pt2ConstMember)(float, char, char) const = NULL;

// C++

class TMyClass
{
public:
   int DoIt(float a, char b, char c){ cout << "TMyClass::DoIt"<< endl; return a+b+c;};
   int DoMore(float a, char b, char c) const
         { cout << "TMyClass::DoMore" << endl; return a-b+c; };

   /* more of TMyClass */
};
pt2ConstMember = &TMyClass::DoIt; // note: <pt2Member> may also legally point to &DoMore

// Calling Function using Function Pointer

(*this.*pt2ConstMember)(12, 'a', 'b');

You can also use the transform property, with required value in scale:

input[type=radio]{transform:scale(2);}

It is simple. Use trim-redux package and write like this in componentDidMount or other place and kill it in componentWillUnmount.

componentDidMount() {
  this.tm = setTimeout(function() {
    setStore({ age: 20 });
  }, 3000);
}

componentWillUnmount() {
  clearTimeout(this.tm);
}

The answers here got me close, but in 2016, I was able to write the following LINQ:

List<ObjectType> objectList = similarTypeList.Select(o =>
    new ObjectType
    {
        PropertyOne = o.PropertyOne,
        PropertyTwo = o.PropertyTwo,
        PropertyThree = o.PropertyThree
    }).ToList();

Use Arrays.equals() if you want to compare the actual content of arrays that contain primitive types values (like byte).

System.out.println(Arrays.equals(aa, bb));

Use Arrays.deepEquals for comparison of arrays that contain objects.

I think that you have a mismatched config for 'fetch' and 'push' so this has caused default fetch/push to not round trip properly. Fortunately you have fetched the branches that you subsequently deleted so you should be able to recreate them with an explicit push.

git push origin origin/contact_page:contact_page origin/new_pictures:new_pictures

according the documentation, this should do it...

Use port number 22 (for sftp) instead of 21 (normal ftp). Solved this problem for me.

You've an number of options, depending on how you want to play it:

isNaN(val)

Returns true if val is not a number, false if it is. In your case, this is probably what you need.

isFinite(val)

Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity

/^\d+$/.test(val)

Returns true if val, when cast to a String, has only digits (probably not what you need).

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

A simple ddply option:

ddply(test,.(id),function(x) head(x,1))

If speed is an issue, a similar approach could be taken with data.table:

testd <- data.table(test)
setkey(testd,id)
testd[,.SD[1],by = key(testd)]

or this might be considerably faster:

testd[testd[, .I[1], by = key(testd]$V1]

I'd use a static constructor on the class that sets the value of a static readonly array.

public class SomeClass
{
   public readonly MyStruct[] myArray;

   public static SomeClass()
   {
      myArray = { {"foo", "bar"},
                  {"boo", "far"}};
   }
}

Just for fun

class A {
    private a1 = void 0;
    private a2 = void 0;
}

class B extends A {
    private a3 = void 0;
    private a4 = void 0;
}

class C extends B {
    private a5 = void 0;
    private a6 = void 0;
}

class Describer {
    private static FRegEx = new RegExp(/(?:this\.)(.+?(?= ))/g); 
    static describe(val: Function, parent = false): string[] {
        var result = [];
        if (parent) {
            var proto = Object.getPrototypeOf(val.prototype);
            if (proto) {
                result = result.concat(this.describe(proto.constructor, parent));
            } 
        }
        result = result.concat(val.toString().match(this.FRegEx) || []);
        return result;
    }
}

console.log(Describer.describe(A)); // ["this.a1", "this.a2"]
console.log(Describer.describe(B)); // ["this.a3", "this.a4"]
console.log(Describer.describe(C, true)); // ["this.a1", ..., "this.a6"]

Update: If you are using custom constructors, this functionality will break.

    //  TO CHECK WHETHER A FILE IS OPENED 
    //  OR NOT (not for .txt files)

    //  the file we want to check
    String fileName = "C:\\Text.xlsx";
    File file = new File(fileName);

    // try to rename the file with the same name
    File sameFileName = new File(fileName);

    if(file.renameTo(sameFileName)){
        // if the file is renamed
        System.out.println("file is closed");    
    }else{
        // if the file didnt accept the renaming operation
        System.out.println("file is opened");
    }

I think this is a simple answer , this will split child devs 50% each based on the parent width.

 <div style="width: 100%">
        <div style="width: 50%; float: left; display: inline-block;">
            Hello world
        </div>
        <div style="width: 50%; display: inline-block;">
            Hello world
        </div>
    </div>

If you are using Webpack > 3 then you only need to install babel-preset-env, since this preset accounts for es2015, es2016 and es2017.

var path = require('path');
let webpack = require("webpack");

module.exports = {
    entry: {
        app: './app/App.js',
        vendor: ["react","react-dom"]
    },
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, '../public')
    },
    module: {
        rules: [{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            use: {
                loader: 'babel-loader?cacheDirectory=true',
            }
        }]
    }
};

This picks up its configuration from my .babelrc file:

{
    "presets": [
        [
            "env",
            {
                "targets": {
                    "browsers":["last 2 versions"],
                    "node":"current"
                }
            }
        ],["react"]
    ]
}

Yes, it is possible. All you have to do is change your query to something like SELECT i.foo, i.bar FROM ObjectName i WHERE i.id = 10. The result of the query will be a List of array of Object. The first element in each array is the value of i.foo and the second element is the value i.bar. See the relevant section of JPQL reference.

The TextBoxFor is a newer MVC input extension introduced in MVC2.

The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:

appcmd set config -section:system.webServer/httpCompression /-[name='xpress']

Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.

Hope it helps others. Cheers

vec1[i] = vec2[i]

will set the value of vec1[i] to the value of vec2[i]. Nothing is inserted. Your second approach is almost correct. Instead of +i+1 you need just +i

v1.insert(v1.begin()+i, v2[i])

The servlet container loads the servlet during startup or when the first request is made. The loading of the servlet depends on the attribute "load-on-startup" in "web.xml" file. If the attribute has a positive integer(0 to 128) then the servlet is load with the loading of the container otherwise it loads when the first request comes for service.

When the servlet is loaded once it gets request then it is called "Lazy loading".

Seems like you want to move around. Try this:

ActiveSheet.UsedRange.select

results in....

If you want to move that selection 3 rows up then try this

ActiveSheet.UsedRange.offset(-3).select

does this...

You can pass the window to your ViewModel using the CommandParameter. See my Example below.

I've implemented an CloseWindow Method which takes a Windows as parameter and closes it. The window is passed to the ViewModel via CommandParameter. Note that you need to define an x:Name for the window which should be close. In my XAML Window i call this method via Command and pass the window itself as a parameter to the ViewModel using CommandParameter.

Command="{Binding CloseWindowCommand, Mode=OneWay}" 
CommandParameter="{Binding ElementName=TestWindow}"

ViewModel

public RelayCommand<Window> CloseWindowCommand { get; private set; }

public MainViewModel()
{
    this.CloseWindowCommand = new RelayCommand<Window>(this.CloseWindow);
}

private void CloseWindow(Window window)
{
    if (window != null)
    {
       window.Close();
    }
}

View

<Window x:Class="ClientLibTestTool.ErrorView"
        x:Name="TestWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:localization="clr-namespace:ClientLibTestTool.ViewLanguages"
        DataContext="{Binding Main, Source={StaticResource Locator}}"
        Title="{x:Static localization:localization.HeaderErrorView}"
        Height="600" Width="800"
        ResizeMode="NoResize"
        WindowStartupLocation="CenterScreen">
    <Grid> 
        <Button Content="{x:Static localization:localization.ButtonClose}" 
                Height="30" 
                Width="100" 
                Margin="0,0,10,10" 
                IsCancel="True" 
                VerticalAlignment="Bottom" 
                HorizontalAlignment="Right" 
                Command="{Binding CloseWindowCommand, Mode=OneWay}" 
                CommandParameter="{Binding ElementName=TestWindow}"/>
    </Grid>
</Window>

Note that i'm using the MVVM light framework, but the principal applies to every wpf application.

This solution violates of the MVVM pattern, because the view-model shouldn't know anything about the UI Implementation. If you want to strictly follow the MVVM programming paradigm you have to abstract the type of the view with an interface.

MVVM conform solution (Former EDIT2)

the user Crono mentions a valid point in the comment section:

Passing the Window object to the view model breaks the MVVM pattern IMHO, because it forces your vm to know what it's being viewed in.

You can fix this by introducing an interface containing a close method.

Interface:

public interface ICloseable
{
    void Close();
}

Your refactored ViewModel will look like this:

ViewModel

public RelayCommand<ICloseable> CloseWindowCommand { get; private set; }

public MainViewModel()
{
    this.CloseWindowCommand = new RelayCommand<IClosable>(this.CloseWindow);
}

private void CloseWindow(ICloseable window)
{
    if (window != null)
    {
        window.Close();
    }
}

You have to reference and implement the ICloseable interface in your view

View (Code behind)

public partial class MainWindow : Window, ICloseable
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

Answer to the original question: (former EDIT1)

Your Login Button (Added CommandParameter):

<Button Name="btnLogin" IsDefault="True" Content="Login" Command="{Binding ShowLoginCommand}" CommandParameter="{Binding ElementName=LoginWindow}"/>

Your code:

 public RelayCommand<Window> CloseWindowCommand { get; private set; } // the <Window> is important for your solution!

 public MainViewModel() 
 {
     //initialize the CloseWindowCommand. Again, mind the <Window>
     //you don't have to do this in your constructor but it is good practice, thought
     this.CloseWindowCommand = new RelayCommand<Window>(this.CloseWindow);
 }

 public bool CheckLogin(Window loginWindow) //Added loginWindow Parameter
 {
    var user = context.Users.Where(i => i.Username == this.Username).SingleOrDefault();

    if (user == null)
    {
        MessageBox.Show("Unable to Login, incorrect credentials.");
        return false;
    }
    else if (this.Username == user.Username || this.Password.ToString() == user.Password)
    {
        MessageBox.Show("Welcome "+ user.Username + ", you have successfully logged in.");
        this.CloseWindow(loginWindow); //Added call to CloseWindow Method
        return true;
    }
    else
    {
        MessageBox.Show("Unable to Login, incorrect credentials.");
        return false;
    }
 }

 //Added CloseWindow Method
 private void CloseWindow(Window window)
 {
     if (window != null)
     {
         window.Close();
     }
 }

You can do like this

DELETE FROM table WHERE id NOT IN ( 2 )

OR

DELETE FROM table WHERE id <>  2 

As @Frank Schmitt noted, you might want to be careful about the NULL values too. If you want to delete everything which is not 2(including the NULLs) then add OR id IS NULL to the WHERE clause.

As I didn't find what I was looking for, I will share what I actually wanted to achieve when I ended in this question.

Scenario: I have 3 different API's with same possible response and therefore I would like to handle the completion and error handling of the promises in a single function. This is what I did:

1. Create a handler function:

  private handleHttpPromise = (promise: Promise<any>) => {
    promise
      .then((response: any) => {
        // do something with the response
        console.log(response);
      })
      .catch((error) => {
        // do something with the error
        console.log(error);
      });
  };

2. Send your promises to the created handler

  switch (method) {
    case 'get': {
      this.handleHttpPromise(apiService.get(url));
      break;
    }
    case 'post': {
      if (jsonData) {
        this.handleHttpPromise(apiService.post(url, jsonData));
      }
      break;
    }
    // (...)
  }

I have been toying with this as well. I initially had it in my documents folder, but decided that didn't make 'philosophical' sense. I decided to create an Android directory in my home folder and place Eclipse and the Android SKK in there.
