In MVC 5 I found that temporarily commenting out references to an Entity Framework model, and recompiling the project side stepped this error when scaffolding. Once I finish scaffolding I uncomment the code.

public Guid CreatedById { get; private set; }
// Commented out so I can scaffold: 
// public virtual UserBase CreatedBy { get; private set; }

The easiest solution is to override SaveChanges on your entities class. You can catch the DbEntityValidationException, unwrap the actual errors and create a new DbEntityValidationException with the improved message.

1. Create a partial class next to your SomethingSomething.Context.cs file.
2. Use the code at the bottom of this post.
3. That's it. Your implementation will automatically use the overriden SaveChanges without any refactor work.

Your exception message will now look like this:

System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The validation errors are: The field PhoneNumber must be a string or array type with a maximum length of '12'; The LastName field is required.

You can drop the overridden SaveChanges in any class that inherits from DbContext:

public partial class SomethingSomethingEntities
{
    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException ex)
        {
            // Retrieve the error messages as a list of strings.
            var errorMessages = ex.EntityValidationErrors
                    .SelectMany(x => x.ValidationErrors)
                    .Select(x => x.ErrorMessage);
    
            // Join the list to a single string.
            var fullErrorMessage = string.Join("; ", errorMessages);
    
            // Combine the original exception message with the new one.
            var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
    
            // Throw a new DbEntityValidationException with the improved exception message.
            throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
        }
    }
}

The DbEntityValidationException also contains the entities that caused the validation errors. So if you require even more information, you can change the above code to output information about these entities.

m0nhawk's answer didn't work for me on Windows 10 - it required elevated command prompt and refused to emit a file.

This worked and didn't require elevation:

reg export HKEY_CURRENT_USER\Software\SimonTatham\PuTTY putty.reg

You can just creates files with the name of the word to print, uses findstr which can print in color, and then erases the file. Try this example:

@echo off
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
  set "DEL=%%a"
)

call :ColorText 0a "green"
call :ColorText 0C "red"
call :ColorText 0b "cyan"
echo(
call :ColorText 19 "blue"
call :ColorText 2F "white"
call :ColorText 4e "yellow"

goto :eof

:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof

Run color /? to get a list of colors.

Fuel UX combobox has all the features you would expect.

I also experienced that for example:

This code doesnt work and get the intended block error.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
return self.title

However, when i press tab before typing return self.title statement, the code works.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
    return self.title

Hope, this will help others.

Won't days * 24 * 60 * 60 * 1000 suffice?

This is the way to convert a entity to XML File and then compress it:

private  void downloadFile(EntityXML xml) {

string nameDownloadXml = "File_1.xml";
string nameDownloadZip = "File_1.zip";

var serializer = new XmlSerializer(typeof(EntityXML));

Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("content-disposition", "attachment;filename=" + nameDownloadZip);

using (var memoryStream = new MemoryStream())
{
    using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
    {
        var demoFile = archive.CreateEntry(nameDownloadXml);
        using (var entryStream = demoFile.Open())
        using (StreamWriter writer = new StreamWriter(entryStream, System.Text.Encoding.UTF8))
        {
            serializer.Serialize(writer, xml);
        }
    }

    using (var fileStream = Response.OutputStream)
    {
        memoryStream.Seek(0, SeekOrigin.Begin);
        memoryStream.CopyTo(fileStream);
    }
}

Response.End();

}

BindingResult is used for validation..

Example:-

 public @ResponseBody String nutzer(@ModelAttribute(value="nutzer") Nutzer nutzer, BindingResult ergebnis){
        String ergebnisText;
        if(!ergebnis.hasErrors()){
            nutzerList.add(nutzer);
            ergebnisText = "Anzahl: " + nutzerList.size();
        }else{
            ergebnisText = "Error!!!!!!!!!!!";
        }
        return ergebnisText;
    }

the _T convention is used to indicate the program should use the character set defined for the application (Unicode, ASCII, MBCS, etc.). You can surround your strings with _T( ) to have them stored in the correct format.

 cout << _T( "There are " ) << argc << _T( " arguments:" ) << endl;

If this is your first push, then you might not care about the history on the remote. You could then do a "force push" to skip checks that git does to prevent you from overwriting any existing, or differing, work on remote. Use with extreme care!

just change the

git push **-u** origin master

change it like this!

git push -f origin master

public static function recursiveDelete($dir)
{
    foreach (new \DirectoryIterator($dir) as $fileInfo) {

                recursiveDelete($fileInfo->getPathname());
            } else {
                unlink($fileInfo->getPathname());
            }

#This creates the main window of an application
window = tk.Tk()
window.title("Join")
window.geometry("300x300")
window.configure(background='grey')

path = "Aaron.jpg"

#Creates a Tkinter-compatible photo image, which can be used everywhere Tkinter expects an image object.
img = ImageTk.PhotoImage(Image.open(path))

#The Label widget is a standard Tkinter widget used to display a text or image on the screen.
panel = tk.Label(window, image = img)

#The Pack geometry manager packs widgets in rows or columns.
panel.pack(side = "bottom", fill = "both", expand = "yes")

#Start the GUI
window.mainloop()

NOTE: The recommended way to do string formatting in Python is to use format(), as outlined in the accepted answer. I'm preserving this answer as an example of the C-style syntax that's also supported.

# NOTE: format() is a better choice!
string1 = "go"
string2 = "now"
string3 = "great"

s = """
I will %s there
I will go %s
%s
""" % (string1, string2, string3)

print(s)

Some reading:

• String formatting
• PEP 3101 -- Advanced String Formatting

The above - findByBookIdRegion() did not work for me. The following works with the latest release of String Data JPA:

I used conda install python-graphviz then conda install pydot and then conda install pydot plus and then it worked.

So:

conda install python-graphviz
conda install pydot
conda install pydotplus

i have been searching for ages and finally i put everything together to find my solution. Folks say, you cannot fade-in/-out the background-image- id of the html-background. Thats definitely wrong as you can figure out by implementing the below mentioned demo

CSS:

html, body

height: 100%;   /* ges Hoehe der Seite -> weitere Hoehenangaben werden relativ hierzu ausgewertet */
overflow: hidden;   /*  hide scrollbars */
opacity: 1.0;
-webkit-transition: background 1.5s linear;
-moz-transition: background 1.5s linear;
-o-transition: background 1.5s linear;
-ms-transition: background 1.5s linear;
transition: background 1.5s linear;

Changing body's background-image can now easily be done using JavaScript:

switch (dummy)

case 1:

$(document.body).css({"background-image": "url("+URL_of_pic_One+")"});
waitAWhile();

case 2:
$(document.body).css({"background-image": "url("+URL_of_pic_Two+")"});
waitAWhile();

YUI has by far the best stylesheet utility I have seen out there. I encourage you to check it out, but here's a taste:

// style element or locally sourced link element
var sheet = YAHOO.util.StyleSheet(YAHOO.util.Selector.query('style',null,true));

sheet = YAHOO.util.StyleSheet(YAHOO.util.Dom.get('local'));


// OR the id of a style element or locally sourced link element
sheet = YAHOO.util.StyleSheet('local');


// OR string of css text
var css = ".moduleX .alert { background: #fcc; font-weight: bold; } " +
          ".moduleX .warn  { background: #eec; } " +
          ".hide_messages .moduleX .alert, " +
          ".hide_messages .moduleX .warn { display: none; }";

sheet = new YAHOO.util.StyleSheet(css);

There are obviously other much simpler ways of changing styles on the fly such as those suggested here. If they make sense for your problem, they might be best, but there are definitely reasons why modifying css is a better solution. The most obvious case is when you need to modify a large number of elements. The other major case is if you need your style changes to involve the cascade. Using the dom to modify an element will always have a higher priority. Its the sledgehammer approach and is equivalent to using the style attribute directly on the html element. That is not always the desired effect.

Since April 2018, Google made some changes to the Autoplay Policy. You not only need to add the autoplay=1 as a query param, but also add allow='autoplay' as an iframe's attribute

So you will have to do something like this:

<iframe src="https://www.youtube.com/embed/VIDEO_ID?autoplay=1" allow='autoplay'></iframe>

there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

[later] you might also want to check out Albert van der Horst's ciasdis: http://home.hccnet.nl/a.w.m.van.der.horst/forthassembler.html. it can be hard to understand, but has some interesting features you won't likely find anywhere else.

fname = "feed.txt"
feed = open(fname, 'r')

num_lines = len(feed.splitlines())
num_words = 0
num_chars = 0

for line in lines:
    num_words += len(line.split())

If you use read_excel() on a file opened using the function open(), make sure to add rb to the open function to avoid encoding errors

This is nothing to do with android as it is java based so you could use

private String getDateTime() { 
   DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
   Date date = new Date(); 
   return dateFormat.format(date); 
}

@MIP is right, but with newer versions of Safari, you will need to add sandbox attribute(HTML5) to give redirect access to the iFrame. There are a few specific values that can be added with a space between them.

Your Activity ( Example ) :

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;

public class Layout extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        Slice mySlice = new Slice(getApplicationContext());
        mySlice.setBackgroundColor(Color.WHITE);
        setContentView(mySlice, new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    }
}

Working Example :

Another absolutely simple Calculate function you may interested in ..

private Path Calculate(Point A, Point B, Point C) {
    Path Pencil = new Path();
    Pencil.moveTo(A.x, A.y);
    Pencil.lineTo(B.x, B.y);
    Pencil.lineTo(C.x, C.y);
    return Pencil;
}

Update: If you are using CLion 2020.2, then it already supports Makefiles. If you are using an older version, read on.

Even though currently only CMake is supported, you can instruct CMake to call make with your custom Makefile. Edit your CMakeLists.txt adding one of these two commands:

• add_custom_target
• add_custom_command

When you tell CLion to run your program, it will try to find an executable with the same name of the target in the directory pointed by PROJECT_BINARY_DIR. So as long as your make generates the file where CLion expects, there will be no problem.

Here is a working example:

Tell CLion to pass its $(PROJECT_BINARY_DIR) to make

This is the sample CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.4)
project(mytest)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

add_custom_target(mytest COMMAND make -C ${mytest_SOURCE_DIR}
                         CLION_EXE_DIR=${PROJECT_BINARY_DIR})

Tell make to generate the executable in CLion's directory

This is the sample Makefile:

all:
    echo Compiling $(CLION_EXE_DIR)/$@ ...
    g++ mytest.cpp -o $(CLION_EXE_DIR)/mytest

That is all, you may also want to change your program's working directory so it executes as it is when you run make from inside your directory. For this edit: Run -> Edit Configurations ... -> mytest -> Working directory

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:

Go to view and press "Switch to scale mode" which will adjust the virtual screen when you adjust the application.

You will get an error if you try to close/disconnect outside of the method. The best solution is to close the connection in both callbacks in the method. The dummy code is here.

const newTodo = new Todo({text:'cook dinner'});

newTodo.save().then((docs) => {
  console.log('todo saved',docs);
  mongoose.connection.close();
},(e) => {
  console.log('unable to save');
});

To do it by using f-string and with control of the number of trailing digits:

print(f'A number -> {my_number:>20.5f}')

Here are my random 5 cents ...

$random=function($a, $b) {
    return(
        substr(str_shuffle(('\\`)/|@'.
        password_hash(mt_rand(0,999999),
        PASSWORD_DEFAULT).'!*^&~(')),
        $a, $b)
    );
};

echo($random(0,5));

PHP's new password_hash() (* >= PHP 5.5) function is doing the job for generation of decently long set of uppercase and lowercase characters and numbers.

Two concat. strings before and after password_hash within $random function are suitable for change.

Paramteres for $random() *($a,$b) are actually substr() parameters. :)

NOTE: this doesn't need to be a function, it can be normal variable as well .. as one nasty singleliner, like this:

$random=(substr(str_shuffle(('\\`)/|@'.password_hash(mt_rand(0,999999), PASSWORD_DEFAULT).'!*^&~(')), 0, 5));

echo($random);

I like the fixed precision of senderle's decimal version, so here's a sort of hybrid of that with joctee's answer above (did you know you could take logs with non-integer bases?):

from math import log
def human_readable_bytes(x):
    # hybrid of https://stackoverflow.com/a/10171475/2595465
    #      with https://stackoverflow.com/a/5414105/2595465
    if x == 0: return '0'
    magnitude = int(log(abs(x),10.24))
    if magnitude > 16:
        format_str = '%iP'
        denominator_mag = 15
    else:
        float_fmt = '%2.1f' if magnitude % 3 == 1 else '%1.2f'
        illion = (magnitude + 1) // 3
        format_str = float_fmt + ['', 'K', 'M', 'G', 'T', 'P'][illion]
    return (format_str % (x * 1.0 / (1024 ** illion))).lstrip('0')

It is very simple:

1. To check the current status of any file in the current dir, whether it is staged or not:

   git status

2. Staging any files:

   git add . for all files in the current directory

   git add <filename> for specific file

3. Unstaging the file:

   git restore --staged <filename>

My main reason for having code like:

try
{
    //Some code
}
catch (Exception e)
{
    throw;
}

is so I can have a breakpoint in the catch, that has an instantiated exception object. I do this a lot while developing/debugging. Of course, the compiler gives me a warning on all the unused e's, and ideally they should be removed before a release build.

They are nice during debugging though.

    listname.extend(element)

multiple_appends(mylist, 4, 5, "string", False)
print(mylist)

OUTPUT:

[1, 2, 3, 4, 5, 'string', False]

Here is how I figured it out. I am behind corporate firewall too.

Go to Chrome or your Internet Settings by clicking the wrench in Chrome --> Settings --> Under the Hood --> Network --> Change Proxy Settings

Click on LAN Settings and then Advanced. Copy the proxy server address and port.

Mostly the connection refused link occurs when trying to download SDK packages through Eclipse.

Navigate to the SDK Manager.exe and double click on it. Once it starts click on Tools --> Options and then enter the proxy server address and the Port #

Check the checkbox force https:// to http:// That's it your SDK Manager will now be able to download packages from google remote site without any issue even from behind a firewall.

I am on Windows by the way. Tried everything and this works great.

The size is four bytes because the enum is stored as an int. With only 12 values, you really only need 4 bits, but 32 bit machines process 32 bit quantities more efficiently than smaller quantities.

0 0 0 0  January
0 0 0 1  February
0 0 1 0  March
0 0 1 1  April
0 1 0 0  May
0 1 0 1  June
0 1 1 0  July
0 1 1 1  August
1 0 0 0  September
1 0 0 1  October
1 0 1 0  November
1 0 1 1  December
1 1 0 0  ** unused **
1 1 0 1  ** unused **
1 1 1 0  ** unused **
1 1 1 1  ** unused **

Without enums, you might be tempted to use raw integers to represent the months. That would work and be efficient, but it would make your code hard to read. With enums, you get efficient storage and readability.

The easy method that will work even in corrupted setup environment is :

To download ez_setup.py and run it using command line

python ez_setup.py

The best way to do it I think is:

if(val != true){
//do something
} 

This will be true if val is false, NaN, or undefined.

The solution below was the best format I found.

log_format postdata escape=json '$remote_addr - $remote_user [$time_local] '
                       '"$request" $status $bytes_sent '
                       '"$http_referer" "$http_user_agent" "$request_body"';
server {
        listen 80;

        server_name api.some.com;

        location / {
         access_log  /var/log/nginx/postdata.log  postdata;
         proxy_pass      http://127.0.0.1:8080;
        }

}

For this input

curl -d '{"key1":"value1", "key2":"value2"}' -H "Content-Type: application/json" -X POST http://api.deprod.com/postEndpoint

Generate that great result

201.23.89.149 -  [22/Aug/2019:15:58:40 +0000] "POST /postEndpoint HTTP/1.1" 200 265 "" "curl/7.64.0" "{\"key1\":\"value1\", \"key2\":\"value2\"}"

File -> Spreadsheet Settings -> (Tab) Calculation -> Recalculation (3 Options)
- On change
- On change and every minute
- On change and every hour
This affects how often NOW, TODAY, RAND, and RANDBETWEEN are updated.

but.. .. it updates only, if the functions arguments (their ranges, cells) are affected by that.
  

from my example
I use google spreadsheet to find out the age of a person. I have his birthday date in the format (dd.mm.yyyy) -> it's the used format here in Switzerland.

=ARRAYFORMULA(IF(ISTEXT(K4:K), IF(TODAY() - DATE(YEAR(TODAY()), MONTH(REGEXREPLACE(K4:K, "[.]", "/")), DAY(REGEXREPLACE(K4:K, "[.]", "/"))) > 0, YEAR(TODAY()) - YEAR(REGEXREPLACE(K4:K, "[.]", "/")) + 1, YEAR(TODAY()) - YEAR(REGEXREPLACE(K4:K, "[.]", "/"))), IF(LEN(K4:K) > 0, IF(TODAY() - DATE(YEAR(TODAY()), MONTH(K4:K), DAY(K4:K)) > 0, YEAR(TODAY()) - YEAR(K4:K) + 1, YEAR(TODAY()) - YEAR(K4:K)), "")))

I'm using TODAY() and I did the recalculation settings described above. -> but no automatically refresh. :-(
It updates only, if I change some value inside the ranges where the function is looking for.

So I wrote a Google Script (Tools -> Script Editor..) for that purpose.

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheetMaster = ss.getSheetByName("Master"); 
  var sortRange = sheetMaster.getRange(firstRow, firstColumn, lastRow, lastColumn);  

  sortRange.getCell(1, 2).setValue(sortRange.getCell(1, 2).getValue());
}

You need to set numbers for firstRow, firstColumn, lastRow, lastColumn

The Script get active when the spreadsheets open, writes the content of one cell into the same cell again. That's enough to trigger the TODAY() function.

Look for more information on that link from Edward Moffett. Force google sheet formula to recalculate

On CYGwin, you can install this as a typical package in the first screen. Look for

libssl-devel

The easiest solution I found, is given on python.org devguide:

sudo apt-get build-dep python3.6

If that package is not available for your system, try reducing the minor version until you find a package that is available in your system’s package manager.

I tried explaining details, on my blog.

Here's a nice way of doing that.

    static bool IsPrime(int n)
    {
        if (n > 1)
        {
            return Enumerable.Range(1, n).Where(x => n%x == 0)
                             .SequenceEqual(new[] {1, n});
        }

        return false;
    }

And a quick way of writing your program will be:

        for (;;)
        {
            Console.Write("Accept number: ");
            int n = int.Parse(Console.ReadLine());
            if (IsPrime(n))
            {
                Console.WriteLine("{0} is a prime number",n);
            }
            else
            {
                Console.WriteLine("{0} is not a prime number",n);
            }
        }

just see how DataInputStream.readInt() is implemented;

    int ch1 = in.read();
    int ch2 = in.read();
    int ch3 = in.read();
    int ch4 = in.read();
    if ((ch1 | ch2 | ch3 | ch4) < 0)
        throw new EOFException();
    return ((ch1 << 24) + (ch2 << 16) + (ch3 << 8) + (ch4 << 0));

If you want just A-Z:

randomAZ(n: number): string {
      return Array(n)
        .fill(null)
        .map(() => Math.random()*100%25 + 'A'.charCodeAt(0))
        .map(a => String.fromCharCode(a))
        .join('')
 }

Try using string.Contains () combined with EndsWith.

var results = from c in db.Customers
              where c.FullName.Contains (FirstName) && c.FullName.EndsWith (LastName)
              select c;

I had the same issue where my firewall was configured properly, TCP/IP was enabled in SQL Server Configuration Manager but I still could not access my SQL database from outside the computer hosting it. I found the solution was SQL Server Browser was disabled by default in Services (and no option was available to enable it in SQL Server Configuration Manager).

I enabled it by Control Panel > Administrative Tools > Services then double click on SQL Server Browser. In the General tab set the startup type to Automatic using the drop down list. Then go back into SQL Server Configuration Manager and check that the SQL Server Browser is enabled. Hope this helps.

Converting a varchar value into an int fails when the value includes a decimal point to prevent loss of data.

If you convert to a decimal or float value first, then convert to int, the conversion works.

Either example below will return 7082:

SELECT CONVERT(int, CONVERT(decimal(12,7), '7082.7758172'));
SELECT CAST(CAST('7082.7758172' as float) as int);

Be aware that converting to a float value may result, in rare circumstances, in a loss of precision. I would tend towards using a decimal value, however you'll need to specify precision and scale values that make sense for the varchar data you're converting.

If you are using mysql client you can set up the resultFormat per session e.g.

mysql -h localhost -u root --resutl-format=json

or

mysql -h localhost -u root --vertical

Check out the full list of arguments here.

For those very beginners who has spend few hours for this commit (with comment and no verify) with no further issue

git commit -m "Some comments" --no-verify

Answers = Answers.GroupBy(a => a.id).Select(x => x.First());

This will select each unique object by email

You can also use following Node.js module to do it with ease:

https://www.npmjs.com/package/mssql-to-csv

var mssqlExport = require('mssql-to-csv')

    // All config options supported by https://www.npmjs.com/package/mssql 
    var dbconfig = {
        user: 'username',
        password: 'pass',
        server: 'servername',
        database: 'dbname',
        requestTimeout: 320000,
        pool: {
            max: 20,
            min: 12,
            idleTimeoutMillis: 30000
        }
    };

    var options = {
        ignoreList: ["sysdiagrams"], // tables to ignore 
        tables: [],                  // empty to export all the tables 
        outputDirectory: 'somedir',
        log: true
    };

    mssqlExport(dbconfig, options).then(function(){
        console.log("All done successfully!");
        process.exit(0);
    }).catch(function(err){
        console.log(err.toString());
        process.exit(-1);
   });

You can use .delay() before an animation, like this:

$("#myElem").show().delay(5000).fadeOut();

If it's not an animation, use setTimeout() directly, like this:

$("#myElem").show();
setTimeout(function() { $("#myElem").hide(); }, 5000);

You do the second because .hide() wouldn't normally be on the animation (fx) queue without a duration, it's just an instant effect.

Or, another option is to use .delay() and .queue() yourself, like this:

$("#myElem").show().delay(5000).queue(function(n) {
  $(this).hide(); n();
});

Rotate the x axis labels with angle equal or smaller than 90 degrees using base graphics. Code adapted from the R FAQ:

par(mar = c(7, 4, 2, 2) + 0.2) #add room for the rotated labels

#use mtcars dataset to produce a barplot with qsec colum information
mtcars = mtcars[with(mtcars, order(-qsec)), ] #order mtcars data set by column "qsec"

end_point = 0.5 + nrow(mtcars) + nrow(mtcars) - 1 #this is the line which does the trick (together with barplot "space = 1" parameter)

barplot(mtcars$qsec, col = "grey50", 
        main = "",
        ylab = "mtcars - qsec", ylim = c(0,5 + max(mtcars$qsec)),
        xlab = "",
        space = 1)
#rotate 60 degrees (srt = 60)
text(seq(1.5, end_point, by = 2), par("usr")[3]-0.25, 
     srt = 60, adj = 1, xpd = TRUE,
     labels = paste(rownames(mtcars)), cex = 0.65)

If you end up with a SecurityException (and the call does not work), You should consider requesting the user permission to make a call as this is considered a dangerous permission:

ActivityCompat.requestPermissions(
    activity,
    new String[] {Manifest.permission.CALL_PHONE},
    1
);

Note this has nothing to do with the manifest permission (that you must have as well)

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

Note that some zip programs have trouble unzipping a CRX like sathish described - if this is the case, try using 7-Zip - http://www.7-zip.org/

You can do this in 2 steps:

1: Change the input type(In your EditText field) in the layout file to android:inputType="number"

2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());

Actually got the same problem. For me worked this easy way:

Adding the data to a Datatable and sort it:

dt.DefaultView.Sort = "columnname";
dt = dt.DefaultView.ToTable();

If you use Material Design in your app then use this

<com.google.android.material.card.MaterialCardView
            android:layout_width="75dp"
            android:layout_height="75dp"
            app:cardCornerRadius="50dp"
            app:strokeWidth="1dp"
            app:strokeColor="@color/black">
            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:id="@+id/circular_image"
                android:scaleType="fitCenter"
                android:src="@drawable/your_img" />
        </com.google.android.material.card.MaterialCardView>

You can't. At the time of writing, the only HTML form element that's designed to be multi-line is <textarea>.

Install a handler for SIGALRM, then use alarm() or ualarm() before a regular blocking recv(). If the alarm goes off, the recv() will return an error with errno set to EINTR.

Replace /res/ with /lib/ in your custom layout nampespace.

xmlns:android="http://schemas.android.com/apk/res/android"

in your case, would be:

xmlns:yourApp="http://schemas.android.com/apk/lib/com.yourAppPackege.yourClass"

I hope it helps.

I needed to convert a single column of strings of form nn.n% to float. I needed to remove the % from the element in each row. The attend data frame has two columns.

attend.iloc[:,1:2]=attend.iloc[:,1:2].applymap(lambda x: float(x[:-1]))

Its an extenstion to the original answer. In my case it takes a dataframe and applies a function to each value in a specific column. The function removes the last character and converts the remaining string to float.

Using the Intl object (or via toLocaleString) is somewhat problematic, but it can be made precise using the formatToParts method and manually putting the parts in order, e.g.

function formatDate(date = new Date()) {_x000D_
  let {day, month, year} = new Intl.DateTimeFormat('en', {_x000D_
    day:'2-digit',_x000D_
    month: 'short',_x000D_
    year: 'numeric'_x000D_
  }).formatToParts(date).reduce((acc, part) => {_x000D_
    if (part.type != 'literal') {_x000D_
      acc[part.type] = part.value;_x000D_
    }_x000D_
    return acc;_x000D_
  }, Object.create(null));_x000D_
  return `${day}-${month}-${year}`;_x000D_
}_x000D_
_x000D_
console.log(formatDate());

Using reduce on the array returned by formatToParts trims out the literals and creates an object with named properties that is then assigned to variables and finally formatted.

This function doesn't always work nicely for languages other than English though as the short month name may have punctuation.

If you try it on CellContentClick Event

Use:

dataGridView1.EndEdit();  //Stop editing of cell.
MessageBox.Show("0 = " + dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString());

In Target>Build Setting>Product name field you can edit that field here.

bootstrap comes with clas btn-lg http://getbootstrap.com/components/#btn-dropdowns-sizing

<div class="btn btn-default btn-block">
  Active
</div>

but if you want to have the button of the width of your column / container add btn-block

<div class="btn btn-default btn-lg">
      Active
    </div>

However this will expand to 100% so make surt ethat you will wrap your button in certain amount of columns e.g. then you know its always stays 3 columns until xs screen

<div class="col-sm-3">
             <div class="btn btn-default btn-block">
          Active
            </div>
        </div>

An alternative approach:

If

• your YAML structure has well defined fields to be used by your app
• AND you may freely add additional fields that won't mess up with your app

then

• at any level you may add a new block text field named like "Description" or "Comment" or "Notes" or whatever

Example:

Instead of

# This comment
# is too long

use

Description: >
  This comment
  is too long

or

Comment: >
    This comment is also too long
    and newlines survive from parsing!

More advantages:

1. If the comments become large and complex and have a repeating pattern, you may promote them from plain text blocks to objects
2. Your app may -in the future- read or update those comments

Starting in SQL Server 2017 the STRING_AGG function is available which simplifies the logic considerably:

select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA

See SQL Fiddle with Demo

In SQL Server you can use FOR XML PATH to get the result:

select distinct t1.FieldA,
  STUFF((SELECT distinct '' + t2.FieldB
         from yourtable t2
         where t1.FieldA = t2.FieldA
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,0,'') data
from yourtable t1;

See SQL Fiddle with Demo

The following SQL statements are nearly equivalent:

SELECT COLUMN_NAME
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE table_name = 'tbl_name'
  [AND table_schema = 'db_name']
  [AND column_name LIKE 'wild']

SHOW COLUMNS
FROM tbl_name
[FROM db_name]
[LIKE 'wild']

Reference: INFORMATION_SCHEMA COLUMNS

From this wikipedia entry:

The JDK is a subset of what is loosely defined as a software development kit (SDK) in the general sense. In the descriptions which accompany their recent releases for Java SE, EE, and ME, Sun acknowledge that under their terminology, the JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.

The "extra software" seems to be Glassfish, MySQL, and NetBeans. This page gives a comparison of the various packages you can get for the Java EE SDK.

TableA LEFT OUTER JOIN TableB is equivalent to TableB RIGHT OUTER JOIN Table A.

In Oracle, (+) denotes the "optional" table in the JOIN. So in your first query, it's a P LEFT OUTER JOIN S. In your second query, it's S RIGHT OUTER JOIN P. They're functionally equivalent.

In the terminology, RIGHT or LEFT specify which side of the join always has a record, and the other side might be null. So in a P LEFT OUTER JOIN S, P will always have a record because it's on the LEFT, but S could be null.

See this example from java2s.com for additional explanation.

To clarify, I guess I'm saying that terminology doesn't matter, as it's only there to help visualize. What matters is that you understand the concept of how it works.

RIGHT vs LEFT

I've seen some confusion about what matters in determining RIGHT vs LEFT in implicit join syntax.

LEFT OUTER JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT *
FROM A, B
WHERE B.column(+) = A.column

All I did is swap sides of the terms in the WHERE clause, but they're still functionally equivalent. (See higher up in my answer for more info about that.) The placement of the (+) determines RIGHT or LEFT. (Specifically, if the (+) is on the right, it's a LEFT JOIN. If (+) is on the left, it's a RIGHT JOIN.)

Types of JOIN

The two styles of JOIN are implicit JOINs and explicit JOINs. They are different styles of writing JOINs, but they are functionally equivalent.

See this SO question.

Implicit JOINs simply list all tables together. The join conditions are specified in a WHERE clause.

Implicit JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

Explicit JOINs associate join conditions with a specific table's inclusion instead of in a WHERE clause.

Explicit JOIN

SELECT *
FROM A
LEFT OUTER JOIN B ON A.column = B.column

These Implicit JOINs can be more difficult to read and comprehend, and they also have a few limitations since the join conditions are mixed in other WHERE conditions. As such, implicit JOINs are generally recommended against in favor of explicit syntax.

What about this solution? It does not rely on knowledge of @staticmethod decorator implementation. Inner class StaticMethod plays as a container of static initialization functions.

class Klass(object):

    class StaticMethod:
        @staticmethod  # use as decorator
        def _stat_func():
            return 42

    _ANS = StaticMethod._stat_func()  # call the staticmethod

    def method(self):
        ret = self.StaticMethod._stat_func() + Klass._ANS
        return ret

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

Use this style attribute for no word wrapping:

white-space: nowrap;

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Ironically, I have what you want, but want something closer to what you had.

I am loading things in dynamically and asynchronously, but with an load callback like so (using dojo and xmlhtpprequest)

  dojo.xhrGet({
    url: 'getCode.php',
    handleAs: "javascript",
    content : {
    module : 'my.js'
  },
  load: function() {
    myFunc1('blarg');
  },
  error: function(errorMessage) {
    console.error(errorMessage);
  }
});

For a more detailed explanation, see here

The problem is that somewhere along the line the code gets evaled, and if there's anything wrong with your code, the console.error(errorMessage); statement will indicate the line where eval() is, not the actual error. This is SUCH a big problem that I am actually trying to convert back to <script> statements (see here.

You can have some JAR library compiled in Java 7, and you have only Java 6 as Java Runtime. It could happen with some new libraries.

I've just set up a quick benchmarking exercise:

Function             time to run 1 million iterations
--------------------------------------------
(int) "123":                0.55029
intval("123"):              1.0115  (183%)

(int) "0":                  0.42461
intval("0"):                0.95683 (225%)

(int) int:                  0.1502
intval(int):                0.65716 (438%)

(int) array("a", "b"):      0.91264
intval(array("a", "b")):    1.47681 (162%)

(int) "hello":              0.42208
intval("hello"):            0.93678 (222%)

On average, calling intval() is two and a half times slower, and the difference is the greatest if your input already is an integer.

I'd be interested to know why though.

Update: I've run the tests again, this time with coercion (0 + $var)

Addendum: I've just come across a slightly unexpected behaviour which you should be aware of when choosing one of these methods:

$x = "11";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11)

$x = "0x11";
(int) $x;      // int(0)
intval($x);    // int(0)
$x + 0;        // int(17) !

$x = "011";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11) (not 9)

_{Tested using PHP 5.3.1}

Here's how I'd do it:

^[^h]*(h(?!ede)[^h]*)*$

Accurate and more efficient than the other answers. It implements Friedl's "unrolling-the-loop" efficiency technique and requires much less backtracking.

If your columns should not contain NULL values, you need to define the columns as NOT NULL as well, otherwise the passed in NULL will be used instead of the default and not produce an error.

If you don't pass in any value to these fields (which requires you to specify the fields that you do want to use), the defaults will be used:

INSERT INTO 
  table1 (field1, field3) 
VALUES   (5,10)

This worked for me:

conda create -n tensorflow python=3.5
activate tensorflow
conda install -c conda-forge tensorflow

Open Anaconda Navigator.

Change the dropdown of "Applications on" from "root" to "tensorflow"

see screenshot

Launch Spyder

Run a little code to validate you're good to go:

import tensorflow as tf
node1 = tf.constant(3, tf.float32)
node2 = tf.constant(4) # also tf.float32 implicitly
print(node1, node2)

or

hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

You can use a scanner instead of try-catch:

Scanner scanner = new Scanner(line).useDelimiter("\n");
if(scanner.hasNextInt()){
    System.out.println("yes, it's an int");
}

There are two reasons I see to use cte's.

To use a calculated value in the where clause. This seems a little cleaner to me than a derived table.

Suppose there are two tables - Questions and Answers joined together by Questions.ID = Answers.Question_Id (and quiz id)

WITH CTE AS
(
    Select Question_Text,
           (SELECT Count(*) FROM Answers A WHERE A.Question_ID = Q.ID) AS Number_Of_Answers
    FROM Questions Q
)
SELECT * FROM CTE
WHERE Number_Of_Answers > 0

Here's another example where I want to get a list of questions and answers. I want the Answers to be grouped with the questions in the results.

WITH cte AS
(
    SELECT [Quiz_ID] 
      ,[ID] AS Question_Id
      ,null AS Answer_Id
          ,[Question_Text]
          ,null AS Answer
          ,1 AS Is_Question
    FROM [Questions]

    UNION ALL

    SELECT Q.[Quiz_ID]
      ,[Question_ID]
      ,A.[ID] AS  Answer_Id
      ,Q.Question_Text
          ,[Answer]
          ,0 AS Is_Question
        FROM [Answers] A INNER JOIN [Questions] Q ON Q.Quiz_ID = A.Quiz_ID AND Q.Id = A.Question_Id
)
SELECT 
    Quiz_Id,
    Question_Id,
    Is_Question,
    (CASE WHEN Answer IS NULL THEN Question_Text ELSE Answer END) as Name
FROM cte    
GROUP BY Quiz_Id, Question_Id, Answer_id, Question_Text, Answer, Is_Question 
order by Quiz_Id, Question_Id, Is_Question Desc, Name

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

Pythonic way to get text from Span tags:

driver.find_element_by_xpath("//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel clear')]").text

A superfast XML Method, if you want to use a stored procedure and pass the comma separated list of Department IDs :

Declare @XMLList xml
SET @XMLList=cast('<i>'+replace(@DepartmentIDs,',','</i><i>')+'</i>' as xml)
SELECT x.i.value('.','varchar(5)') from @XMLList.nodes('i') x(i))

If you're trying to check if someone is 18 years of age, using timedelta will not work correctly on some edge cases because of leap years. For example, someone born on January 1, 2000, will turn 18 exactly 6575 days later on January 1, 2018 (5 leap years included), but someone born on January 1, 2001, will turn 18 exactly 6574 days later on January 1, 2019 (4 leap years included). Thus, you if someone is exactly 6574 days old, you can't determine if they are 17 or 18 without knowing a little more information about their birthdate.

The correct way to do this is to calculate the age directly from the dates, by subtracting the two years, and then subtracting one if the current month/day precedes the birth month/day.

On a single click the event was processed twice by both jquery instances. One closed and one opened the toggle.

Take a look at Blaze-Persistence Entity Views which works on top of JPA and provides first class DTO support. You can project anything to attributes within Entity Views and it will even reuse existing join nodes for associations if possible.

Here is an example mapping

@EntityView(Order.class)
interface OrderSummary {
  Integer getId();
  @Mapping("SUM(orderPositions.price * orderPositions.amount * orderPositions.tax)")
  BigDecimal getOrderAmount();
  @Mapping("COUNT(orderPositions)")
  Long getItemCount();
}

Fetching this will generate a JPQL/HQL query similar to this

SELECT
  o.id,
  SUM(p.price * p.amount * p.tax),
  COUNT(p.id)
FROM
  Order o
LEFT JOIN
  o.orderPositions p
GROUP BY
  o.id

Here is a blog post about custom subquery providers which might be interesting to you as well: https://blazebit.com/blog/2017/entity-view-mapping-subqueries.html

This line:

layout = (LinearLayout) findViewById(R.id.statsviewlayout);

Looks for the "statsviewlayout" id in your current 'contentview'. Now you've set that here:

setContentView(new GraphTemperature(getApplicationContext()));

And i'm guessing that new "graphTemperature" does not set anything with that id.

It's a common mistake to think you can just find any view with findViewById. You can only find a view that is in the XML (or appointed by code and given an id).

The nullpointer will be thrown because the layout you're looking for isn't found, so

layout.addView(buyButton);

Throws that exception.

addition: Now if you want to get that view from an XML, you should use an inflater:

layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);

assuming that you have your linearlayout in a file called "yourXMLYouWantToLoad.xml"

Install sshpass using, apt-get install sshpass then edit the script and put your linux machines IPs, usernames and password in respective order. After that run that script. Thats it ! This script will install VLC in all systems.

#!/bin/bash
SCRIPT="cd Desktop; pwd;  echo -e 'PASSWORD' | sudo -S apt-get install vlc"
HOSTS=("192.168.1.121" "192.168.1.122" "192.168.1.123")
USERNAMES=("username1" "username2" "username3")
PASSWORDS=("password1" "password2" "password3")
for i in ${!HOSTS[*]} ; do
     echo ${HOSTS[i]}
     SCR=${SCRIPT/PASSWORD/${PASSWORDS[i]}}
     sshpass -p ${PASSWORDS[i]} ssh -l ${USERNAMES[i]} ${HOSTS[i]} "${SCR}"
done

I'm sure neither of these options were available in C# when you asked the question but nowadays you can do it like the following:

// Return with ternary conditional operator.
private bool CheckAll()
{
    return (your_condition) ? true : false;
}

// Alternatively as an expression bodied method.
private bool CheckAll() => (your_condition) ? true : false;

I had a similar problem with a nested dictionary with some numpy.ndarrays in it.

def jsonify(data):
    json_data = dict()
    for key, value in data.iteritems():
        if isinstance(value, list): # for lists
            value = [ jsonify(item) if isinstance(item, dict) else item for item in value ]
        if isinstance(value, dict): # for nested lists
            value = jsonify(value)
        if isinstance(key, int): # if key is integer: > to string
            key = str(key)
        if type(value).__module__=='numpy': # if value is numpy.*: > to python list
            value = value.tolist()
        json_data[key] = value
    return json_data

Here is a good starting point.

HTML:

<div class="containing-table">
    <div class="centre-align">
        <div class="content"></div>
    </div>
</div>

CSS:

.containing-table {
    display: table;
    width: 100%;
    height: 400px; /* for demo only */
    border: 1px dotted blue;
}
.centre-align {
    padding: 10px;
    border: 1px dashed gray;
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}
.content {
    width: 50px;
    height: 50px;
    background-color: red;
    display: inline-block;
    vertical-align: top; /* Removes the extra white space below the baseline */
}

See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/

.containing-table establishes the width and height context for .centre-align (the table-cell).

You can apply text-align and vertical-align to alter .centre-align as needed.

Note that .content needs to use display: inline-block if it is to be centered horizontally using the text-align property.

Mergesort is the best you can do here.

Another reason to avoid the single statement version (single var) is debugging. If an exception is thrown in any of the assignment lines the stack trace shows only the one line.

If you had 10 variables defined with the comma syntax you have no way to directly know which one was the culprit.

The individual statement version does not suffer from this ambiguity.

You can do the following:

Assuming your container div has a class "yellow".

.yellow div {
    // Apply margin to every child in this container
    margin: 10px;
}

.yellow div:first-child, .yellow div:nth-child(3n+1) {
    // Remove the margin on the left side on the very first and then every fourth element (for example)
    margin-left: 0;
}

.yellow div:last-child {
    // Remove the right side margin on the last element
    margin-right: 0;
}

The number 3n+1 equals every fourth element outputted and will clearly only work if you know how many will be displayed in a row, but it should illustrate the example. More details regarding nth-child here.

Note: For :first-child to work in IE8 and earlier, a <!DOCTYPE> must be declared.

Note2: The :nth-child() selector is supported in all major browsers, except IE8 and earlier.

In my case, for jboss 6.3 I had to change JAVA_OPTS in file jboss-eap-6.3\bin\standalone.conf.bat and set following values -Xmx8g -Xms8g -Xmn3080m for jvm to take 8gb space.

In PHP.js, $_COOKIE is a function ;-)

function $_COOKIE(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
    if (c.indexOf(nameEQ) == 0) return decodeURIComponent(c.substring(nameEQ.length,c.length).replace(/\+/g, '%20'));
    }
    return null;
}

This is fairly easy to answer from the internet. Set system properties http.proxyHost and http.proxyPort. You can do this with System.setProperty(), or from the command line with the -D syntax.

Yes, something like this:

SELECT
    id,
    action_heading,
    CASE
        WHEN action_type = 'Income' THEN action_amount
        ELSE NULL
    END AS income_amt,
    CASE
        WHEN action_type = 'Expense' THEN action_amount
        ELSE NULL
    END AS expense_amt

FROM tbl_transaction;

As other answers have pointed out, MySQL also has the IF() function to do this using less verbose syntax. I generally try to avoid this because it is a MySQL-specific extension to SQL that isn't generally supported elsewhere. CASE is standard SQL and is much more portable across different database engines, and I prefer to write portable queries as much as possible, only using engine-specific extensions when the portable alternative is considerably slower or less convenient.

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

Matlab and Scilab languages offer a simpler and more elegant syntax than Python for the question you're asking, so I think the best you can do is to mimic Matlab/Scilab by using the Numpy package in Python. By doing this the solution to your problem is very concise and elegant:

from numpy import *
property_a = array([545., 656., 5.4, 33.])
property_b = array([ 1.2,  1.3, 2.3, 0.3])
good_objects = [True, False, False, True]
good_indices = [0, 3]
property_asel = property_a[good_objects]
property_bsel = property_b[good_indices]

Numpy tries to mimic Matlab/Scilab but it comes at a cost: you need to declare every list with the keyword "array", something which will overload your script (this problem doesn't exist with Matlab/Scilab). Note that this solution is restricted to arrays of number, which is the case in your example.

this.dtOptions = {
    order: [],
    columnDefs: [ {
        'targets': [0], /* column index [0,1,2,3]*/
        'orderable': false, /* true or false */
    }],
    ........ rest all stuff .....
}

The above worked fine for me.

(I am using Angular version 7, angular-datatables version 6.0.0 and bootstrap version 4)

The whole creating and dispatching events works, but since you are using the onchange attribute, your life can be a little simpler:

http://jsfiddle.net/xwywvd1a/3/

var selEl = document.getElementById("sel");
selEl.options[1].selected = true;
selEl.onchange();

If you use the browser's event API (addEventListener, IE's AttachEvent, etc), then you will need to create and dispatch events as others have pointed out already.

filenames must sort correctly to combine correctly!

file1.bin file2.bin ... file10.bin wont work properly

file01.bin file02.bin ... file10.bin will work properly

c:>for %i in (file*.bin) do type %i >> onebinary.bin

Works for ascii or binary files.

First create a table in the database with same numbers of columns that are in the csv file.

Then use following query

LOAD DATA INFILE 'D:/Projects/testImport.csv' INTO TABLE cardinfo
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'

Personally, I would fix this in the .htaccess file. You should have access to that.

Define your CSS URL as such:

url(/image_dir/image.png);

In your .htacess file, put:

Options +FollowSymLinks
RewriteEngine On
RewriteRule ^image_dir/(.*) subdir/images/$1

or

RewriteRule ^image_dir/(.*) images/$1

depending on the site.

I had the same problem with Firefox 30 + Selenium 2.49 + Ubuntu 15.04.

It worked fine with Ubuntu 14 but after upgrade to 15.04 I got same RANDR warning and problem at starting Firefox using Xfvb.

After adding +extension RANDR it worked again.

Try MtPutty, you can automate the ssh login in it. Its a great tool especially if you need to login to multiple servers many times. Try it here

Another tool worth trying is TeraTerm. Its really easy to use for the ssh automation stuff. You can get it here. But my favorite one is always MtPutty.

In this case I might just simply avoid regular expressions altogether and go with something like:

if (StringToTest.IndexOf("ab") < 0)
  //do stuff

This is likely also going to be much faster (a quick test vs regexes above showed this method to take about 25% of the time of the regex method). In general, if I know the exact string I'm looking for, I've found regexes are overkill. Since you know you don't want "ab", it's a simple matter to test if the string contains that string, without using regex.

Call me overly cautious, but I like to make mine more portable because it's unsafe to assume that files will always be in the same place on every computer. Personally I have the code look up the file path first. I use Linux so mine would look like this:

import os, sys
from subprocess import Popen, PIPE
try:
    path = Popen("find / -name 'file' -type f", shell=True, stdout=PIPE).stdout.read().splitlines()[0]
    if not sys.path.__contains__(path):
        sys.path.append(path)
except IndexError:
    raise RuntimeError("You must have FILE to run this program!")

That is of course unless you plan to package these together. But if that's the case you don't really need two separate files anyway.

Phil Haak has an example that I think is a bit more stable when dealing with paths with crazy "\" style directory separators. It also safely handles path concatenation. It comes for free in System.IO

var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);

However, you could also try "AppDomain.CurrentDomain.BaseDirector" instead of "Server.MapPath".

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

Sublime CodeFormatter has formatting support for PHP, JavaScript/JSON/JSONP, HTML, CSS, Python. Although I haven't used CodeFormatter for very long, I have been impressed with it's JS, HTML, and CSS "beautifying" capabilities. I haven't tried using it with PHP (I don't do any PHP development) or Python (which I have no experience with) but both languages have many options in the .sublime-settings file.

One note however, the settings aren't very easy to find. On Windows you will need to go to your %AppData%\Roaming\Sublime Text #\Packages\CodeFormatter\CodeFormatter.sublime-settings. As I don't have a Mac I'm not sure where the settings file is on OS X.

As for a shortcut key, I added this key binding to my "Key Bindings - User" file:

{
    "keys": ["ctrl+k", "ctrl+d"],
    "command": "code_formatter"
}

I use Ctrl + K, Ctrl + D because that's what Visual Studio uses for formatting. You can change it, of course, just remember that what you choose might conflict with some other feature's keyboard shortcut.

Update:

It seems as if the developers of Sublime Text CodeFormatter have made it easier to access the .sublime-settings file. If you install CodeFormatter with the Package Control plugin, you can access the settings via the Preferences -> Package Settings -> CodeFormatter -> Settings - Default and override those settings using the Preferences -> Package Settings -> CodeFormatter -> Settings - User menu item.

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

Try using flexbox. As an example, the following code shows the CSS for the container div inside which the contents needs to be centered aligned:

.absolute-center {
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;

    -ms-flex-align: center;
    -webkit-align-items: center;

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

Demo: https://material.angularjs.org/latest/demo/

There is another way to accomplish that (described in more details in Stephen Walther's Pager example

Essentially, you create a link in the view:

Html.ActionLink("Next page", "Index", routeData)

In routeData you can specify name/value pairs (e.g., routeData["page"] = 5), and in the controller Index function corresponding parameters receive the value. That is,

public ViewResult Index(int? page)

will have page passed as 5. I have to admit, it's quite unusual that string ("page") automagically becomes a variable - but that's how MVC works in other languages as well...

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

In Linux/CygWin a handy script I use at times is:

#Extract the jar (war or ear)
cd dir1
jar xvf jar-file1
for i in `ls *.class`
do
 javap $i > ${i}.txt #list the functions/variables etc
done

cd dir2
jar xvf jar-file2
for i in `ls *.class`
do
 javap $i > ${i}.txt #list the functions/variables etc
done

diff -r dir1 dir2 #diff recursively

Could do this, but then the user has to separate the numbers by a space:

#include "stdio.h"

int main()
{
    int minx, x, y, z;

    printf("Enter four ints: ");
    scanf( "%i %i %i %i", &minx, &x, &y, &z);

    printf("You wrote: %i %i %i %i", minx, x, y, z);
}

I accidentally ran our (largeish) application on a 64bit VM rather than a 32bit VM and didn't notice until some external libraries (called by JNI) started failing.

Data serialized on a 32bit platform was read in on the 64bit platform with no issues at all.

What sort of issues are you getting? Do some things work and not others? Have you tried attaching JConsole etc and have a peak around?

If you have a very big VM you may find that GC issues in 64 bit can affect you.

select * into newtable from oldtable

the class is called:

.form-control { border-radius: 0; }

be sure to insert the override after including bootstraps css.

If you ONLY want to remove the radius on select form-controls use

select.form-control { ... }

instead

EDIT: works for me on chrome, firefox, opera, and safari, IE9+ (all running on linux/safari & IE on playonlinux)

There is no shortcut for converting from int[] to List<Integer> as Arrays.asList does not deal with boxing and will just create a List<int[]> which is not what you want. You have to make a utility method.

int[] ints = {1, 2, 3};
List<Integer> intList = new ArrayList<Integer>(ints.length);
for (int i : ints)
{
    intList.add(i);
}

Just for the sake of people who landed here for the same reason I did:

Don't use reserved keywords

I named a function in my class definition delete(), which is a reserved keyword and should not be used as a function name. Renaming it to deletion() (which also made sense semantically in my case) resolved the issue.

For a list of reserved keywords: http://en.cppreference.com/w/cpp/keyword

I quote: "Since they are used by the language, these keywords are not available for re-definition or overloading. "

.NET 5 will be a unified version of all .NET variants coming in November 2020, so there will be no need to choose between variants anymore.

public boolean equalMaps(Map<?, ?> map1, Map<?, ?>map2) {

    if (map1==null || map2==null || map1.size() != map2.size()) {
        return false;
    }

    for (Object key: map1.keySet()) {
        if (!map1.get(key).equals(map2.get(key))) {
            return false;
        }
    }
    return true;
}

Ok, but what about common in almost every language way items[len(items) - 1]? This is IMO the easiest way to get last element, because it does not require anything pythonic knowledge.

In my case, I needed to do a replacement of Localhost to the actual database server IP address

Instead of

 Connection con = DriverManager.getConnection(
 "jdbc:mysql://localhost:3306/DBname", "root", "root");

I needed

 Connection con = DriverManager.getConnection(
 "jdbc:mysql://192.100.0.000:3306/DBname", "root", "root");

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

I had to resort to a clean install of Windows 7 x64 to fix this issue.

I tried all steps/variants in the other answers. No luck. Device Manager would show my 'Android Device / Android Composite ADB Interface' working properly with the 7.0.0.1 driver from Google, but nothing could get 'adb devices' to show my Nexus 4.

I used USBDeview to uninstall every USB device that had connected to my computer except my keyboard and mouse. No luck.

I enabled 'Show hidden devices' in Device Manager and uninstalled anything related to USB. No luck.

I added Google's vendor ID to adb_usb.ini. No luck. I deleted adb_usb.ini and ran 'android update adb'. No luck.

I brought my Nexus 4 to my brother's apartment to confirm it wasn't faulty. Worked on his machine without a hiccup.

I'm glad the clean install worked, because further troubleshooting was going to require swapping motherboards or buying a MacBook.

Boy, that escalated quickly.

In addition to Mark Proctor's answer:

If you want to keep the default styling, but have a conditional coloring on the button, just set the backgroundTint property like so:

android:backgroundTint="@drawable/styles_mybutton"

Create the associated file /res/drawable/styles_mybutton.xml, then use the following template and change the colors as per your tastes:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Disabled state-->
    <item android:state_enabled="false"
        android:color="@android:color/white">
    </item>
    <!-- Default state-->
    <item
        android:color="#cfc">
    </item>
</selector>

Be aware that the child selector is not supported in Internet Explorer 6. (If you use the selector in a jQuery/Prototype/YUI etc selector rather than in a style sheet it still works though)

Find some interesting defintion:

If you want multiple lines consider this:

<textarea rows="2"></textarea>

Specify rows as needed.

Or if the role is not the owner of any db objects one can use:

DROP ROLE IF EXISTS my_user;
CREATE ROLE my_user LOGIN PASSWORD 'my_password';

But only if dropping this user will not make any harm.

This is as good as passing variable arguments by means of a dictionary

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

import pandas as pd

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

df1_grouped = df1.groupby('atable')

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

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

    print(");")

Just pick the columns you want directly....

df[['A','E','I','C']]

To parse the date string using String.replace with backreference:

var milli = "/Date(1245398693390)/".replace(/\/Date\((-?\d+)\)\//, '$1');
var d = new Date(parseInt(milli));

You need to use the doubleValue() method to get the double value from a BigDecimal object.

BigDecimal bd; // the value you get
double d = bd.doubleValue(); // The double you want

You can do it with a table, like this:

<table width="100%">
  <tr>
    <td style="width: 50%">Left Text</td>
    <td style="width: 50%; text-align: right;">Right Text</td>
  </tr>
</table>

Or, you can do it with CSS like this:

<div style="float: left;">
    Left text
</div>
<div style="float: right;">
    Right text
</div>

Odd to say I remember it because it is the opposite of the typewriter I used.
Well if it was normal I had no need to remember it... :-)

^{*Image from Wikipedia}

In the typewriter when you finish to digit the line you use the carriage return lever, that before makes roll the drum, the newline, and after allow you to manually operate the carriage return.

You can listen from this record from freesound.org the sound of the paper feeding in the beginning, and at around -1:03 seconds from the end, after the bell warning for the end of the line sound of the drum that rolls and after the one of the carriage return.

HI Jasper,

you can do this:

<?
sprintf("<a href=\"http://www.whatever.com/%s\">Click Here</a>", $param);
?>

For me, you can't. But if that suits your needs, you could have speed and formatting by copying the whole range at once, instead of looping:

range("B2:B5002").Copy Destination:=Sheets("Output").Cells(startrow, 2)

And, by the way, you can build a custom range string, like Range("B2:B4, B6, B11:B18")

edit: if your source is "sparse", can't you just format the destination at once when the copy is finished ?

in android 3.1.1 we cant find sync project in tools so C:\Users\AndroidStudioProjects\projectname\.idea\libraries remove the files from libraries and sync again

c can be used on lists (and not only on vectors):

# you have
l1 = list(2, 3)
l2 = list(4)

# you want
list(2, 3, 4)
[[1]]
[1] 2

[[2]]
[1] 3

[[3]]
[1] 4

# you can do
c(l1, l2)
[[1]]
[1] 2

[[2]]
[1] 3

[[3]]
[1] 4

If you have a list of lists, you can do it (perhaps) more comfortably with do.call, eg:

do.call(c, list(l1, l2))

Exactly what Kamil said,

element = this.$el

But make sure you don't have fragment instances.

Try this

hasName = name ? 'Y' : 'N';

Just do:

cd /home/user/.ssh/ -> here user will be your username, i.e. /home/jon/ for example.

Then

gedit known_hosts & and delete the contents inside it.

Now ssh again, it should work.

you can use reflect.TypeOf.

• basic type(e.g.: int, string): it will return its name (e.g.: int, string)
• struct: it will return something in the format <package name>.<struct name> (e.g.: main.test)

Determine whether the list of names is different with each query or reused. If it is reused, it belongs to the database.

Even if it is unique with each query, it may be useful to load it to a temporary table (#table syntax) for performance reasons - in that case you will be able to avoid recompilation of a complex query.

If the maximum number of names is fixed, you should use a parametrized query.

However, if none of the above cases applies, I would go with inlining the names in the query as in your approach #1.

You don't need to use complicated coding really!

Greyscale Hover:

-webkit-filter: grayscale(100%);

Greyscale "Hover-out":

-webkit-filter: grayscale(0%);

I simply made my css class have a separate hover class and added in the second greyscale. It's really simple if you really don't like complexity.

git bash is a shell where:

• the running process is sh.exe (packaged with msysgit, as share/WinGit/Git Bash.vbs)
• git is a known command
• $HOME is defined

See "Fix msysGit Portable $HOME location":

On a Windows 64:

C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"

This differs from git-cmd.bat, which provides git commands in a plain DOS command prompt.

A tool like GitHub for Windows (G4W) provides different shell for git (including a PowerShell one)

Update April 2015:

Note: the git bash in msysgit/Git for windows 1.9.5 is an old one:

GNU bash, version 3.1.20(4)-release (i686-pc-msys)
Copyright (C) 2005 Free Software Foundation, Inc.

But with the phasing out of msysgit (Q4 2015) and the new Git For Windows (Q2 2015), you now have Git for Windows 2.3.5.
It has a much more recent bash, based on the 64bits msys2 project, an independent rewrite of MSYS, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. msys2 comes with its own installer too.

The git bash is now (with the new Git For Windows):

GNU bash, version 4.3.33(3)-release (x86_64-pc-msys)
Copyright (C) 2013 Free Software Foundation, Inc.

Original answer (June 2013) More precisely, from msygit wiki:

Historically, Git on Windows was only officially supported using Cygwin.
To help make a native Windows version, this project was started, based on the mingw fork.

To make the milky 'soup' of project names more clear, we say like this:

• msysGit - is the name of this project, a build environment for Git for Windows, which releases the official binaries
• MinGW - is a minimalist development environment for native Microsoft Windows applications.
  It is really a very thin compile-time layer over the Microsoft Runtime; MinGW programs are therefore real Windows programs, with no concept of Unix-style paths or POSIX niceties such as a fork() call
• MSYS - is a Bourne Shell command line interpreter system, is used by MinGW (and others), was forked in the past from Cygwin
• Cygwin - a Linux like environment, which was used in the past to build Git for Windows, nowadays has no relation to msysGit

So, your two lines description about "git bash" are:

"Git bash" is a msys shell included in "Git for Windows", and is a slimmed-down version of Cygwin (an old version at that), whose only purpose is to provide enough of a POSIX layer to run a bash.

Reminder:

msysGit is the development environment to compile Git for Windows. It is complete, in the sense that you just need to install msysGit, and then you can build Git. Without installing any 3rd-party software.

msysGit is not Git for Windows; that is an installer which installs Git -- and only Git.

See more in "Difference between msysgit and Cygwin + git?".

Ended up using eclipse.ini fix:

openFile
-vm (Your Java Home JDK here)

For example, -vm C:\Java\JDK\1.6.

Had to also change JRE to JDK:

In Eclipse IDE go to:

1. Window -> Preferences -> Installed JREs
2. Click on Add (to locate new JRE)
3. Select standard JVM -> next
4. Click on Directory to locate JRE home, put JDK_INSTALL_LOCATION and finish.
5. Go to your java project's Properties -> Java build Path -> Libraries -> select JRE -> Edit -> select Workspace default JRE -> finish
6. Do a full workspace cleanup with project -> clean.

1-liner

$end = preg_replace( '%^(.+)/%', '', $url );

// if( ! $end ) no match.

This simply removes everything before the last slash, including it.

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

It turns out that because of a peculiar mixture of javascript frameworks that I needed to initiate the script using an event listener provide by one of the other frameworks.

you just need to put this

Checked this on many complex and obfuscated scripts:

var js = "alert('Hello, World!');" // put your JS code here
var oScript = document.createElement("script");
var oScriptText = document.createTextNode(js);
oScript.appendChild(oScriptText);
document.body.appendChild(oScript);

const args = ['p0', 'p1', 'p2'];
call_me.apply(this, args);

See MDN docs for Function.prototype.apply().

If the environment supports ECMAScript 6, you can use a spread argument instead:

call_me(...args);

There is an extension called Hinterland for jupyter, which automatically displays the drop down menu when typing. There are also some other useful extensions.

If 2016+, here is yet another option to dynamically unpivot data without actually using Dynamic SQL.

Example

Declare @YourTable Table ([ID] varchar(50),[Col1] varchar(50),[Col2] varchar(50))
Insert Into @YourTable Values 
 (1,'A','B')
,(2,'R','C')
,(3,'X','D')

Select A.[ID]
      ,Item  = B.[Key]
      ,Value = B.[Value]
 From  @YourTable A
 Cross Apply ( Select * 
                From  OpenJson((Select A.* For JSON Path,Without_Array_Wrapper )) 
                Where [Key] not in ('ID','Other','Columns','ToExclude')
             ) B

Returns

ID  Item    Value
1   Col1    A
1   Col2    B
2   Col1    R
2   Col2    C
3   Col1    X
3   Col2    D

This happens to me once: I uninstalled the IIS, and the port 80 still was used. Well the problem was that also I had the Report Service of the Sql Server 2012 installed, so I stopped that service and the problems solves.

Use this method:

private Long secondsBetween(Date first, Date second){
    return (second.getTime() - first.getTime())/1000;
}

You can use the function RESHAPE:

B = reshape(A.',1,[]);

You can use the following steps:

Step 1: Create a requirements.txt with list of packages to be installed. If you want to copy packages in a particular environment, do this

pip freeze >> requirements.txt

else store package names in a file named requirements.txt

Step 2: Execute pip command with this file

pip install -r requirements.txt

You should validate your JSON string here.

A valid JSON string must have double quotes around the keys:

JSON.parse({"u1":1000,"u2":1100})       // will be ok

If there are no quotes, it will cause an error:

JSON.parse({u1:1000,u2:1100})    
// error Uncaught SyntaxError: Unexpected token u in JSON at position 2

Using single quotes will also cause an error:

JSON.parse({'u1':1000,'u2':1100})    
// error Uncaught SyntaxError: Unexpected token ' in JSON at position 1

Your form is being submitted already as your button is type submit. Which in most browsers would result in a form submission and loading of the server response rather than executing javascript on the page.

Change the type of the submit button to a button. Also, as this button is given the id submit, it will cause a conflict with Javascript's submit function. Change the id of this button. Try something like

<input type="button" value="Submit" id="btnsubmit" onclick="submitForm()">

Another issue in this instance is that the name of the form contains a - dash. However, Javascript translates - as a minus.

You will need to either use array based notation or use document.getElementById() / document.getElementsByName(). The getElementById() function returns the element instance directly as Id is unique (but it requires an Id to be set). The getElementsByName() returns an array of values that have the same name. In this instance as we have not set an id, we can use the getElementsByName with index 0.

Try the following

function submitForm() {
   // Get the first form with the name
   // Usually the form name is not repeated
   // but duplicate names are possible in HTML
   // Therefore to work around the issue, enforce the correct index
   var frm = document.getElementsByName('contact-form')[0];
   frm.submit(); // Submit the form
   frm.reset();  // Reset all form data
   return false; // Prevent page refresh
}

Essentially Matt Daley/Johnny Mohseni's solution worked for me.

Once 1.3.0-beta1 change was saved, I got a prompt to upgrade dependencies. Upon accepting the request to upgrade, the gradle build status bar at the bottom tracked the packages being synced. When that completed, the build was automatically triggered and completed successfully.

The right way to do this, starting with Spring 4.1, is to use a @TestPropertySource annotation.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:whereever/context.xml")
@TestPropertySource(properties = {"myproperty = foo"})
public class TestWarSpringContext {
    ...    
}

See @TestPropertySource in the Spring docs and Javadocs.

This is a simple example :

List<String> citiesName = Arrays.asList( "Delhi","Mumbai","Chennai","Banglore","Kolkata");
System.out.println("Cities : "+citiesName);
List<String> sortedByName = citiesName.stream()
                .sorted((s1,s2)->s2.compareTo(s1))
                        .collect(Collectors.toList());
System.out.println("Sorted by Name : "+ sortedByName);

It may be possible that your IDE is not getting the jdk 1.8 or upper version to compile the code.

Set the Java version 1.8 for Your_Project > properties > Project Facets > Java version 1.8

I assume you have defined custom adapter for your ListView.

If this is the case then you can assign onClickListener for your button inside the custom adapter's getView() method.

here is the solution:

#wrapper {
    width: 500px;
    border: 1px solid black;
    overflow: auto; /* so the size of the wrapper is alway the size of the longest content */
}
#first {
    float: left;
    width: 300px;
    border: 1px solid red;
}
#second {
    border: 1px solid green;
    margin: 0 0 0 302px; /* considering the border you need to use a margin so the content does not float under the first div*/
}

Ok I realised that you can do this:

1. In Xcode > Window > Devices, select a connected iPhone/iPad/etc top left.
2. View Device Logs
3. All Logs

You probably have a lot of logs there, and to make it easier to find your imported log later, you could just go ahead and delete all logs at this point... unless they mean money to you. Or unless you know the exact point of time the crash happened - it should be written in the file anyway... I'm lazy so I just delete all old logs (this actually took a while).

4. Just drag and drop your file into that list. It worked for me.
