I've found out that the container id can be found in /proc/self/cgroup

So you can get the id with :

cat /proc/self/cgroup | grep -o  -e "docker-.*.scope" | head -n 1 | sed "s/docker-\(.*\).scope/\\1/"

I ran into the same problem. One issue might be OpenCV is created for Python 2.7, not 3 (not all python 2.7 libraries will work in python 3 or greater). I also don't believe you can download OpenCV directly through PyCharm's package installer. I have found luck following the instructions: OpenCV Python. Specifically:

1. Downloading and installing OpenCV from SourceForge
2. Copying the cv2.pyd file from the download (opencv\build\python\2.7\x64) into Python's site-packages folder (something like: C:\Python27\Lib\site-packages)
3. In PyCharm, open the python Console (Tools>Python Console) and type:import cv2, and assuming no errors print cv2.__version__

Alternatively, I have had luck using this package opencv-python, which you can straightforwardly install using pip with pip install opencv-python

Good luck!

Everyone seems to want to tell you what you should be doing rather than just answering the question.

The problem is that you're running the module as '__main__' by passing the mod1.py as an argument to the interpreter.

From PEP 328:

Relative imports use a module's __name__ attribute to determine that module's position in the package hierarchy. If the module's name does not contain any package information (e.g. it is set to '__main__') then relative imports are resolved as if the module were a top level module, regardless of where the module is actually located on the file system.

In Python 2.6, they're adding the ability to reference modules relative to the main module. PEP 366 describes the change.

Update: According to Nick Coghlan, the recommended alternative is to run the module inside the package using the -m switch.

The following code is working fine. Run the code snippet what it does.

Shorter way is do it as follows:

private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};

I was able to get all errors via the below code:

ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
error_reporting(-1);

Try this:

function funcName() {
    alert("test");
}

var run = setInterval(funcName, 10000)

If you don't intend to have any telephone numbers on your page, then <meta name="format-detection" content="telephone=no"> will work just fine. But rhetorically speaking, what if you intend to use a mix of phone and non-phone numbers?

Assuming you're just hard-coding numbers into your HTML, the "insert stuff in the middle of your digits" hacks will work. But they are of little to no use for dynamic pages, such as using PHP to output numerical data from a query.

As an example, I was generating a list of city populations. Some of the populations were large enough to cause Mobile Safari to turn them into phone number links. Fortunately, all I had to do was use PHP number_format() around the array output to insert "thousands" commas:

<?php echo number_format($row["population"]) ?>

This formatting was enough to convince Mobile Safari that there was a somewhat more specific purpose for the number, so it didn't default my larger numbers into telephone links anymore. The same would hold true for the suggestion by @davidcondrey of using <a href="tel:18001234567">1-800-123-4567</a> to specify a purpose to the number.

Bottom line is that Safari Mobile apparently does pay attention to semantics. Given that HTML5 is built around semantic markup, and search engines are relying on semantic markup, I intend to use it as much as I can.

Alternate solution to doing shallow clone (git clone --depth=1 <URL>) would be, if remote side supports it, to use --remote option of git archive:

$ git archive --format=tar --remote=<repository URL> HEAD | tar xf -

Or, if remote repository in question is browse-able using some web interface like gitweb or GitHub, then there is a chance that it has 'snapshot' feature, and you can download latest version (without versioning information) from web interface.

You need to have the pointer to point somewhere to use it.

Try this code:

char word[64];
scanf("%s", word);

This creates a character array of lenth 64 and reads input to it. Note that if the input is longer than 64 bytes the word array overflows and your program becomes unreliable.

As Jens pointed out, it would be better to not use scanf for reading strings. This would be safe solution.

char word[64]
fgets(word, 63, stdin);
word[63] = 0;

string toBeSearched = "code : ";
string code = myString.Substring(myString.IndexOf(toBeSearched) + toBeSearched.Length);

Something like this?

Perhaps you should handle the case of missing code :...

string toBeSearched = "code : ";
int ix = myString.IndexOf(toBeSearched);

if (ix != -1) 
{
    string code = myString.Substring(ix + toBeSearched.Length);
    // do something here
}

This looks like a CSV file, so you could use the python csv module to read it. For example:

import csv

crimefile = open(fileName, 'r')
reader = csv.reader(crimefile)
allRows = [row for row in reader]

Using the csv module allows you to specify how things like quotes and newlines are handled. See the documentation I linked to above.

A Possible Gotcha

Recommended Sanity Check - Make sure to add the form-control class to your inputs.

If you have bootstrap css loaded on your page, but your inputs don't have the
class="form-control" then placeholder CSS selector won't apply to them.

Example markup from the docs:

I know this didn't apply to the OP's markup but as I missed this at first and spent a little bit of effort trying to debug it, I'm posting this answer to help others.

A gcc spec file can do the job, however all users on the machine will be affected.

See here

I prefer onKeyUp since it only fires when the key is released. onKeyDown, on the other hand, will fire multiple times if for some reason the user presses and holds the key. For example, when listening for "pressing" the Enter key to make a network request, you don't want that to fire multiple times since it can be expensive.

// handler could be passed as a prop
<input type="text" onKeyUp={handleKeyPress} />

handleKeyPress(e) {
if (e.key === 'Enter') {
  // do whatever
}

}

Also, stay away from keyCode since it will be deprecated some time.

Learning to use smart pointers is in my opinion one of the most important steps to become a competent C++ programmer. As you know whenever you new an object at some point you want to delete it.

One issue that arise is that with exceptions it can be very hard to make sure a object is always released just once in all possible execution paths.

This is the reason for RAII: http://en.wikipedia.org/wiki/RAII

Making a helper class with purpose of making sure that an object always deleted once in all execution paths.

Example of a class like this is: std::auto_ptr

But sometimes you like to share objects with other. It should only be deleted when none uses it anymore.

In order to help with that reference counting strategies have been developed but you still need to remember addref and release ref manually. In essence this is the same problem as new/delete.

That's why boost has developed boost::shared_ptr, it's reference counting smart pointer so you can share objects and not leak memory unintentionally.

With the addition of C++ tr1 this is now added to the c++ standard as well but its named std::tr1::shared_ptr<>.

I recommend using the standard shared pointer if possible. ptr_list, ptr_dequeue and so are IIRC specialized containers for pointer types. I ignore them for now.

So we can start from your example:

std::vector<gate*> G; 
G.push_back(new ANDgate);  
G.push_back(new ORgate); 
for(unsigned i=0;i<G.size();++i) 
{ 
  G[i]->Run(); 
} 

The problem here is now that whenever G goes out scope we leak the 2 objects added to G. Let's rewrite it to use std::tr1::shared_ptr

// Remember to include <memory> for shared_ptr
// First do an alias for std::tr1::shared_ptr<gate> so we don't have to 
// type that in every place. Call it gate_ptr. This is what typedef does.
typedef std::tr1::shared_ptr<gate> gate_ptr;    
// gate_ptr is now our "smart" pointer. So let's make a vector out of it.
std::vector<gate_ptr> G; 
// these smart_ptrs can't be implicitly created from gate* we have to be explicit about it
// gate_ptr (new ANDgate), it's a good thing:
G.push_back(gate_ptr (new ANDgate));  
G.push_back(gate_ptr (new ORgate)); 
for(unsigned i=0;i<G.size();++i) 
{ 
   G[i]->Run(); 
} 

When G goes out of scope the memory is automatically reclaimed.

As an exercise which I plagued newcomers in my team with is asking them to write their own smart pointer class. Then after you are done discard the class immedietly and never use it again. Hopefully you acquired crucial knowledge on how a smart pointer works under the hood. There's no magic really.

As @Ian explained, the problem is that jQuery's click() is not the same as the native one.

Therefore, consider using vanilla-js instead of jQuery:

var a = document.createElement('a');
a.href = "img.png";
a.download = "output.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

Demo

Use count(*)

declare 
   cnt integer;
begin
  SELECT count(*) INTO cnt
  FROM people
  WHERE person_id = my_person_id;

IF cnt > 0 THEN
  -- Do something
END IF;

Edit (for the downvoter who didn't read the statement and others who might be doing something similar)

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)

Because of that where clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

The singular form dtype is used to check the data type for a single column. And the plural form dtypes is for data frame which returns data types for all columns. Essentially:

For a single column:

dataframe.column.dtype

For all columns:

dataframe.dtypes

Example:

import pandas as pd
df = pd.DataFrame({'A': [1,2,3], 'B': [True, False, False], 'C': ['a', 'b', 'c']})

df.A.dtype
# dtype('int64')
df.B.dtype
# dtype('bool')
df.C.dtype
# dtype('O')

df.dtypes
#A     int64
#B      bool
#C    object
#dtype: object

This answer is a modification to mangu23 answer
I only added a for loop to avoid repetition and to easily add more fragments without boilerplate code.

We first need a list of the fragments that should be displayed

public class MainActivity extends AppCompatActivity{
    //...
    List<Fragment> fragmentList = new ArrayList<>();
}

Then we need to fill it with our fragments

@Override
protected void onCreate(Bundle savedInstanceState) {
    //...
    HomeFragment homeFragment = new HomeFragment();
    MessagesFragment messagesFragment = new MessagesFragment();
    UserFragment userFragment = new UserFragment();
    FavoriteFragment favoriteFragment = new FavoriteFragment();
    MapFragment mapFragment = new MapFragment();

    fragmentList.add(homeFragment);
    fragmentList.add(messagesFragment);
    fragmentList.add(userFragment);
    fragmentList.add(favoriteFragment);
    fragmentList.add(mapFragment);
}

And we need a way to know which fragment were selected from the list, so we need getFragmentIndex function

private int getFragmentIndex(Fragment fragment) {
    int index = -1;
    for (int i = 0; i < fragmentList.size(); i++) {
        if (fragment.hashCode() == fragmentList.get(i).hashCode()){
            return i;
        }
    }
    return index;
}

And finally, the displayFragment method will like this:

private void displayFragment(Fragment fragment) {
        int index = getFragmentIndex(fragment);
        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
        if (fragment.isAdded()) { // if the fragment is already in container
            transaction.show(fragment);
        } else { // fragment needs to be added to frame container
            transaction.add(R.id.placeholder, fragment);
        }
        // hiding the other fragments
        for (int i = 0; i < fragmentList.size(); i++) {
            if (fragmentList.get(i).isAdded() && i != index) {
                transaction.hide(fragmentList.get(i));
            }
        }
        transaction.commit();
    }

In this way, we can call displayFragment(homeFragment) for example.
This will automatically show the HomeFragment and hide any other fragment in the list.
This solution allows you to append more fragments to the fragmentList without having to repeat the if statements in the old displayFragment version.
I hope someone will find this useful.

SELECT * FROM news WHERE date > DATEADD(d,-1,GETDATE())

If you have the need to keep the environment variables in a script you can put your command in a here document like this. Especially if you have lots of variables to set things look tidy this way.

# prepare a script e.g. for running maven
runmaven=/tmp/runmaven$$
# create the script with a here document 
cat << EOF > $runmaven
#!/bin/bash
# run the maven clean with environment variables set
export ANT_HOME=/usr/share/ant
export MAKEFLAGS=-j4
mvn clean install
EOF
# make the script executable
chmod +x $runmaven
# run it
sudo $runmaven
# remove it or comment out to keep
rm $runmaven

Have you looked in firebug if POST or GET?.

check the console display.

Put in the test script:

console.log(data);

You can see the response from the server, if it shows something.

I recently created a component called SwipeableView as subclass of UIView, written in Swift 5.1 . It support all 4 direction, has several customisation options and can animate and interpolate different attributes and items ( such as layout constraints, background/tint color, affine transform, alpha channel and view center, all of them demoed with the respective show case ). It also supports the swiping coordination with the inner scroll view if set or auto detected. Should be pretty easy and straightforward to be used ( I hope )

This one worked for me.

window.open("data:application/octet-stream;charset=utf-16le;base64,"+data64);

This one worked too

 let a = document.createElement("a");
 a.href = "data:application/octet-stream;base64,"+data64;
 a.download = "documentName.pdf"
 a.click();

I think that you can just catch org.openqa.selenium.NoSuchElementException that will be thrown by driver.findElement if there's no such element:

import org.openqa.selenium.NoSuchElementException;

....

public static void assertLinkNotPresent(WebDriver driver, String text) {
    try {
        driver.findElement(By.linkText(text));
        fail("Link with text <" + text + "> is present");
    } catch (NoSuchElementException ex) { 
        /* do nothing, link is not present, assert is passed */ 
    }
}

What's the default superuser username/password for postgres after a new install?:

CAUTION The answer about changing the UNIX password for "postgres" through "$ sudo passwd postgres" is not preferred, and can even be DANGEROUS!

This is why: By default, the UNIX account "postgres" is locked, which means it cannot be logged in using a password. If you use "sudo passwd postgres", the account is immediately unlocked. Worse, if you set the password to something weak, like "postgres", then you are exposed to a great security danger. For example, there are a number of bots out there trying the username/password combo "postgres/postgres" to log into your UNIX system.

What you should do is follow Chris James's answer:

sudo -u postgres psql postgres

# \password postgres

Enter new password: 

To explain it a little bit...

I think Microsoft guide for ASP.NET Identity is a good start.

https://docs.microsoft.com/en-us/aspnet/identity/overview/features-api/account-confirmation-and-password-recovery-with-aspnet-identity

Note:

If you do not use AccountController and wan't to reset your password, use Request.GetOwinContext().GetUserManager<ApplicationUserManager>();. If you dont have the same OwinContext you need to create a new DataProtectorTokenProvider like the one OwinContext uses. By default look at App_Start -> IdentityConfig.cs. Should look something like new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));.

Could be created like this:

Without Owin:

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));
    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

With Owin:

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

The DpapiDataProtectionProvider and DataProtectorTokenProvider needs to be created with the same name for a password reset to work. Using Owin for creating the password reset token and then creating a new DpapiDataProtectionProvider with another name won't work.

Code that I use for ASP.NET Identity:

Web.Config:

<add key="AllowedHosts" value="example.com,example2.com" />

    {
        Body = body,

Here buddy. This function will match your date with any specific date and will be able to tell whether they match or not. You can also modify the components to match your requirements.

- (BOOL)isSameDay:(NSDate*)date1 otherDay:(NSDate*)date2 {
NSCalendar* calendar = [NSCalendar currentCalendar];

unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit;
NSDateComponents* comp1 = [calendar components:unitFlags fromDate:date1];
NSDateComponents* comp2 = [calendar components:unitFlags fromDate:date2];

return [comp1 day]   == [comp2 day] &&
[comp1 month] == [comp2 month] &&
[comp1 year]  == [comp2 year];}

I'll right simple example show you the right way to use wait and notify in Java. So I'll create two class named ThreadA & ThreadB. ThreadA will call ThreadB.

public class ThreadA {
    public static void main(String[] args){
        ThreadB b = new ThreadB();//<----Create Instance for seconde class
        b.start();//<--------------------Launch thread

        synchronized(b){
            try{
                System.out.println("Waiting for b to complete...");
                b.wait();//<-------------WAIT until the finish thread for class B finish
            }catch(InterruptedException e){
                e.printStackTrace();
            }

            System.out.println("Total is: " + b.total);
        }
    }
} 

and for Class ThreadB:

class ThreadB extends Thread{
    int total;
    @Override
    public void run(){
        synchronized(this){
            for(int i=0; i<100 ; i++){
                total += i;
            }
            notify();//<----------------Notify the class wich wait until my    finish 
//and tell that I'm finish
            }
        }
    }

I really struggled to find a way to read a binary file into a byte array in C++ that would output the same hex values I see in a hex editor. After much trial and error, this seems to be the fastest way to do so without extra casts. By default it loads the entire file into memory, but only prints the first 1000 bytes.

string Filename = "BinaryFile.bin";
FILE* pFile;
pFile = fopen(Filename.c_str(), "rb");
fseek(pFile, 0L, SEEK_END);
size_t size = ftell(pFile);
fseek(pFile, 0L, SEEK_SET);
uint8_t* ByteArray;
ByteArray = new uint8_t[size];
if (pFile != NULL)
{
    int counter = 0;
    do {
        ByteArray[counter] = fgetc(pFile);
        counter++;
    } while (counter <= size);
    fclose(pFile);
}
for (size_t i = 0; i < 800; i++) {
    printf("%02X ", ByteArray[i]);
}

If you are doing ES2015 or doing type script and ES5 then you can use arrow functions in your code and you don't face that error and this refers to your desired scope in your instance.

this.name = 'test'
myObject.doSomething(data => {
  console.log(this.name)  // this should print out 'test'
});

As an explanation: In ES2015 arrow functions capture this from their defining scope. Normal function definitions don't do that.

From https://spark.apache.org/docs/1.5.1/api/java/org/apache/spark/sql/DataFrame.html, use join:

Inner equi-join with another DataFrame using the given column.

PersonDf.join(ProfileDf,$"personId")

OR

PersonDf.join(ProfileDf,PersonDf("personId") === ProfileDf("personId"))

Update:

You can also save the DFs as temp table using df.registerTempTable("tableName") and you can write sql queries using sqlContext.

Detecting and Correcting the ObjectID Error

I stumbled into this problem when trying to delete an item using mongoose and got the same error. After looking over the return string, I found there were some extra spaces inside the returned string which caused the error for me. So, I applied a few of the answers provided here to detect the erroneous id then remove the extra spaces from the string. Here is the code that worked for me to finally resolve the issue.

const mongoose = require("mongoose");
mongoose.set('useFindAndModify', false);  //was set due to DeprecationWarning: Mongoose: `findOneAndUpdate()` and `findOneAndDelete()` without the `useFindAndModify`



app.post("/delete", function(req, res){
  let checkedItem = req.body.deleteItem;
  if (!mongoose.Types.ObjectId.isValid(checkedItem)) {
    checkedItem = checkedItem.replace(/\s/g, '');
  }

  Item.findByIdAndRemove(checkedItem, function(err) {
    if (!err) {
      console.log("Successfully Deleted " + checkedItem);
        res.redirect("/");
      }
    });
});

This worked for me and I assume if other items start to appear in the return string they can be removed in a similar way.

I hope this helps.

I created my own little lazy Math-Object for degree (MathD), hope it helps:

//helper
/**
 * converts degree to radians
 * @param degree
 * @returns {number}
 */
var toRadians = function (degree) {
    return degree * (Math.PI / 180);
};

/**
 * Converts radian to degree
 * @param radians
 * @returns {number}
 */
var toDegree = function (radians) {
    return radians * (180 / Math.PI);
}

/**
 * Rounds a number mathematical correct to the number of decimals
 * @param number
 * @param decimals (optional, default: 5)
 * @returns {number}
 */
var roundNumber = function(number, decimals) {
    decimals = decimals || 5;
    return Math.round(number * Math.pow(10, decimals)) / Math.pow(10, decimals);
}
//the object
var MathD = {
    sin: function(number){
        return roundNumber(Math.sin(toRadians(number)));
    },
    cos: function(number){
        return roundNumber(Math.cos(toRadians(number)));
    },
    tan: function(number){
        return roundNumber(Math.tan(toRadians(number)));
    },
    asin: function(number){
        return roundNumber(toDegree(Math.asin(number)));
    },
    acos: function(number){
       return roundNumber(toDegree(Math.acos(number)));
   },
   atan: function(number){
       return roundNumber(toDegree(Math.atan(number)));
   }
};

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

I'm giving you the fiddle_demo

The Java Date and Calendar classes are considered by many to be poorly designed. You should take a look at Joda Time, a library commonly used in lieu of Java's built-in date libraries.

The equivalent of DateTime.Now in Joda Time is:

DateTime dt = new DateTime();

Update

As noted in the comments, the latest versions of Joda Time have a DateTime.now() method, so:

DateTime dt = DateTime.now();

cp -r ls -A | grep -v "Excluded_File_or_folder" ../$target_location -v

You could just add a few COUNTIF statements together:

=COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree")

This will give you the result you need.

EDIT

Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND condition the right way. Here's an alternative that should give you the correct results, which you were pretty close to in the first place:

=SUM(COUNTIFS(A1:A196,{"yes","no"},J1:J196,"agree"))

That's not possible. localhost always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.

If you want to access it e.g. in a browser, connect to it using the local IP instead:

http://192.168.180.1:8000

This is just an example of course, you can find out the actual IP by issuing an ifconfig command on a shell in the guest operating system.

You could do it something like this:

    $.each(data, function(idx, obj){

    //Outer .each loop is for traversing the JSON rows
    tblSomething += '<tr>';

    //Inner .each loop is for traversing JSON columns
    $.each(obj, function(key, value){
    tblSomething += '<td>' + value + '</td>';

    tblSomething += '</tr>';
    });

    tblSomething += '</tbody>';

    $('#tblSomething').html(tblSomething);
    },
    error: function(jqXHR, textStatus, errorThrown){
    alert('Hey, something went wrong because: ' + errorThrown);
    }
    });


    });
    </script>


    <table id = "tblSomething" class = "table table-hover"></table>

You're really close. Try using a large row number with End(xlUp)

Function ultimaFilaBlanco(col As String) As Long

        Dim lastRow As Long
        With ActiveSheet
            lastRow = ActiveSheet.Cells(1048576, col).End(xlUp).row
        End With

        ultimaFilaBlanco = lastRow

End Function

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

Comment space too small, so here is some more information for you on the use of static final. As I said in my comment to the Andrzej's answer, only primitive and String are compiled directly into the code as literals. To demonstrate this, try the following:

You can see this in action by creating three classes (in separate files):

public class DisplayValue {
    private String value;

    public DisplayValue(String value) {
        this.value = value;
    }

    public String toString() {
        return value;
    }
}

public class Constants {
    public static final int INT_VALUE = 0;
    public static final DisplayValue VALUE = new DisplayValue("A");
}

public class Test {
    public static void main(String[] args) {
        System.out.println("Int   = " + Constants.INT_VALUE);
        System.out.println("Value = " + Constants.VALUE);
    }
}

Compile these and run Test, which prints:

Int    = 0
Value  = A

Now, change Constants to have a different value for each and just compile class Constants. When you execute Test again (without recompiling the class file) it still prints the old value for INT_VALUE but not VALUE. For example:

public class Constants {
    public static final int INT_VALUE = 2;
    public static final DisplayValue VALUE = new DisplayValue("X");
}

Run Test without recompiling Test.java:

Int    = 0
Value  = X

Note that any other type used with static final is kept as a reference.

Similar to C/C++ #if/#endif, a constant literal or one defined through static final with primitives, used in a regular Java if condition and evaluates to false will cause the compiler to strip the byte code for the statements within the if block (they will not be generated).

private static final boolean DEBUG = false;

if (DEBUG) {
    ...code here...
}

The code at "...code here..." would not be compiled into the byte code. But if you changed DEBUG to true then it would be.

If you want to dump all tables from all databases and with no data (only database and table structures) you may use:

mysqldump -P port -h hostname_or_ip -u username -p --no-data --all-databases > db_backup.sql

This will produce a .sql file that you can load onto a mysql server to create a fresh database. Use cases for this are not many in a production environment, but I do this on a weekly basis to reset servers which are linked to demo websites, so whatever the users do during the week, on sunday nights everything rolls back to "new" :)

Try this

$('#checkbox1').click(function() {
        if (!this.checked) {
            var sure = confirm("Are you sure?");
            this.checked = sure;
            $('#textbox1').val(sure.toString());
        }
    });

declare class member
static int i = 0;

mNotificationManager.notify(++i, mBuilder.build());

A common idiom is to use the comma operator which evaluates both operands, and returns the second operand. Thus:

for(int i = 0; i != 5; ++i,++j) 
    do_something(i,j);

But is it really a comma operator?

Now having wrote that, a commenter suggested it was actually some special syntactic sugar in the for statement, and not a comma operator at all. I checked that in GCC as follows:

int i=0;
int a=5;
int x=0;

for(i; i<5; x=i++,a++){
    printf("i=%d a=%d x=%d\n",i,a,x);
}

I was expecting x to pick up the original value of a, so it should have displayed 5,6,7.. for x. What I got was this

i=0 a=5 x=0
i=1 a=6 x=0
i=2 a=7 x=1
i=3 a=8 x=2
i=4 a=9 x=3

However, if I bracketed the expression to force the parser into really seeing a comma operator, I get this

int main(){
    int i=0;
    int a=5;
    int x=0;

    for(i=0; i<5; x=(i++,a++)){
        printf("i=%d a=%d x=%d\n",i,a,x);
    }
}

i=0 a=5 x=0
i=1 a=6 x=5
i=2 a=7 x=6
i=3 a=8 x=7
i=4 a=9 x=8

Initially I thought that this showed it wasn't behaving as a comma operator at all, but as it turns out, this is simply a precedence issue - the comma operator has the lowest possible precedence, so the expression x=i++,a++ is effectively parsed as (x=i++),a++

Thanks for all the comments, it was an interesting learning experience, and I've been using C for many years!

I had this issue with AOSP (clang).

Add external\libcxx\include to includes and _LIBCPP_COMPILER_CLANG to symbols

This has nothing to do with a malformed upload. The HTTP error clearly specifies 401 unauthorized, and tells you the CSRF token is invalid. Try sending a valid CSRF token with the upload.

The error message points to a problem with your Java version. Do you have a JDK installed?

Try adding the following (noting the new line):

/!\ make sure, that the -vm option occurs before the -vmargs command. Everything after -vmargs is passed directly to the JVM.

-vm 
c:/wherever/java/jdk1.6.0_21/jre/bin/server/jvm.dll
-vmargs... 

...to your eclipse.ini file, pointing to the JDK you want to use, and check that the required Java version is at least as new as your JDK. This is the path for a Windows system. More on paths can be found here (scroll down).

If you don't know where the eclipse.ini file is: regularly it is in the folder of your eclipse.exe.

Edit2: @KadoLakatt: the reason why installing the latest Java Version worked for you is because Eclipse checks the standard path for a JVM if it doesn't find a -vm entry (see here). However I'd not recommend that, since you might be wrong guessing the JVM used. If you update Java (automatically?) you might run into problems in your Eclipse wondering what you might have changed. Better set it to a specific folder in your eclipse.ini to be certain.

I think the lightsail as the name suggest is light weight and meant for initial development. For production sites and apps with high volume it simply becomes unavailable and hangs....It is just a sandbox to play with things. Further lack of support reduces its reliability. There should be an option to migrate to EC2, when u fully develop your apps or sites..So that with same minimum configuration you can migrate to scalable EC2..

You need to change your Ajax call to

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    contentType: "json",
    processData: false,
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

change the dataType to contentType and add the processData option.

To retrieve the JSON payload from your controller, use:

dd(json_decode($request->getContent(), true));

instead of

dd($request->all());

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),
               write_csv(data, "readr_file.csv"),
               fwrite(data, "datatable_file.csv"),
               times = 10, unit = "s")

## Unit: seconds
##                                              expr        min         lq       mean     median         uq        max neval
##  write.csv(data, "baseR_file.csv", row.names = F) 13.8066424 13.8248250 13.9118324 13.8776993 13.9269675 14.3241311    10
##                 write_csv(data, "readr_file.csv")  3.6742610  3.7999409  3.8572456  3.8690681  3.8991995  4.0637453    10

If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test using a standard user account. So it will hit the url but because of having no write permission file won't be saved.. This method is working fine for me as i am using this method for a cronjob. Thanks.

sthx

Andy Hayden mentioned the correct function (to_sql). In this answer, I'll give a complete example, which I tested with Python 3.5 but should also work for Python 2.7 (and Python 3.x):

First, let's create the dataframe:

# Create dataframe
import pandas as pd
import numpy as np

np.random.seed(0)
number_of_samples = 10
frame = pd.DataFrame({
    'feature1': np.random.random(number_of_samples),
    'feature2': np.random.random(number_of_samples),
    'class':    np.random.binomial(2, 0.1, size=number_of_samples),
    },columns=['feature1','feature2','class'])

print(frame)

Which gives:

   feature1  feature2  class
0  0.548814  0.791725      1
1  0.715189  0.528895      0
2  0.602763  0.568045      0
3  0.544883  0.925597      0
4  0.423655  0.071036      0
5  0.645894  0.087129      0
6  0.437587  0.020218      0
7  0.891773  0.832620      1
8  0.963663  0.778157      0
9  0.383442  0.870012      0

To import this dataframe into a MySQL table:

# Import dataframe into MySQL
import sqlalchemy
database_username = 'ENTER USERNAME'
database_password = 'ENTER USERNAME PASSWORD'
database_ip       = 'ENTER DATABASE IP'
database_name     = 'ENTER DATABASE NAME'
database_connection = sqlalchemy.create_engine('mysql+mysqlconnector://{0}:{1}@{2}/{3}'.
                                               format(database_username, database_password, 
                                                      database_ip, database_name))
frame.to_sql(con=database_connection, name='table_name_for_df', if_exists='replace')

One trick is that MySQLdb doesn't work with Python 3.x. So instead we use mysqlconnector, which may be installed as follows:

pip install mysql-connector==2.1.4  # version avoids Protobuf error

Output:

Note that to_sql creates the table as well as the columns if they do not already exist in the database.

I have found that the 65536 limit still applies to pivot tables, even in Excel 2007.

Just use window.open():

window.open('Prosjektplan.pdf')

Anyway, what guys are saying on comments is true. You better use <a target="_blank"> instead of click events.

To late for the original asker of the question, but with SQL Server 2008 R2 this is now possible:

Set the property "Pagebreak" on the tablix or table or other element to force a new tab, and then set the property "Pagename" on both the element before the pagebreak and the element after the pagebreak. These names will appear on the tabs when the report is exported to Excel.

See if this helps: Back to CSV - Convert CSV text to Objects; via JSON

This is a blog post published in November 2008 that includes C# code to provide a solution.

From the intro on the blog post:

As Json is easier to read and write then Xml. It follows that CSV (comma seperated values) is easier to read and write then Json. CSV also has tools such as Excel and others that make it easy to work with and create. So if you ever want to create a config or data file for your next app, here is some code to convert CSV to JSON to POCO objects

very simple

$('#label-ID').text("label value which you want to set");

Ok, solved it myself;

def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'ls /badDir'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout\nerr> $serr"

displays:

out> err> ls: cannot access /badDir: No such file or directory

When creating an array like that, its size must be constant. If you want a dynamically sized array, you need to allocate memory for it on the heap and you'll also need to free it with delete when you're done:

//allocate the array
int** arr = new int*[row];
for(int i = 0; i < row; i++)
    arr[i] = new int[col];

// use the array

//deallocate the array
for(int i = 0; i < row; i++)
    delete[] arr[i];
delete[] arr;

If you want a fixed size, then they must be declared const:

const int row = 8;
const int col = 8;
int arr[row][col];

Also,

int [row][col];

doesn't even provide a variable name.

Try Base64 encoding/decoding your binary data. Also look into CDATA sections

To change to a directory with spaces on the name you just have to type like this:

cd My\ Documents

Hit enter and you will be good

More or less this page has answers but all are not at one place. I was dealing with the same issue and spent quite a good time on it. Now i have a better understanding and i would like to share it here:

I Enabling Swagger ui with Spring websecurity:

If you have enabled Spring Websecurity by default it will block all the requests to your application and returns 401. However for the swagger ui to load in the browser swagger-ui.html makes several calls to collect data. The best way to debug is open swagger-ui.html in a browser(like google chrome) and use developer options('F12' key ). You can see several calls made when the page loads and if the swagger-ui is not loading completely probably some of them are failing.

you may need to tell Spring websecurity to ignore authentication for several swagger path patterns. I am using swagger-ui 2.9.2 and in my case below are the patterns that i had to ignore:

However if you are using a different version your's might change. you may have to figure out yours with developer option in your browser as i said before.

@Configuration

II Enabling swagger ui with interceptor

Generally you may not want to intercept requests that are made by swagger-ui.html. To exclude several patterns of swagger below is the code:

Most of the cases pattern for web security and interceptor will be same.

@Configuration
@EnableWebMvc
public class RetrieveCiamInterceptorConfiguration implements WebMvcConfigurer {

@Autowired
RetrieveInterceptor validationInterceptor;

@Override
public void addInterceptors(InterceptorRegistry registry) {

    registry.addInterceptor(validationInterceptor).addPathPatterns("/**")
    .excludePathPatterns("/v2/api-docs", "/configuration/ui", 
            "/swagger-resources/**", "/configuration/**", "/swagger-ui.html"
            , "/webjars/**", "/csrf", "/");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
      .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
      .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

}

Since you may have to enable @EnableWebMvc to add interceptors you may also have to add resource handlers to swagger similar to i have done in the above code snippet.

!apt install unzip

then use unzip to extract your files:

!unzip  source.zip -d destination.zip

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
    System.out.println(LocalDate.parse("08/16/2011", dateFormatter));

Output:

2011-08-16

I am contributing the modern answer. The answer by Bohemian is correct and was a good answer when it was written 6 years ago. Now the notoriously troublesome SimpleDateFormat class is long outdated and we have so much better in java.time, the modern Java date and time API. I warmly recommend you use this instead of the old date-time classes.

What went wrong in your code?

When I parse 08/16/2011 using your snippet, I get Sun Jan 16 00:08:00 CET 2011. Since lowercase mm is for minutes, I get 00:08:00 (8 minutes past midnight), and since uppercase DD is for day of year, I get 16 January.

In java.time too format pattern strings are case sensitive, and we needed to use uppercase MM for month and lowercase dd for day of month.

Question: Can I use java.time with my Java version?

Yes, java.time works nicely on Java 6 and later and on both older and newer Android devices.

• In Java 8 and later and on new Android devices (from API level 26, I’m told) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the new classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

Use a ContentProvider and load you data using a 'CursorLoader'. With this architecture your data will be automatically reloaded on database changes. Use third-party frameworks for your ContentProvider - you don't really want to implement it by yourself...

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

If your string (In your case the variable text) could be null this would make a big Difference:

1-string.IsNullOrEmpty(text.Trim()) --> EXCEPTION since your calling a mthode of a null object

2-string.IsNullOrWhiteSpace(text) This would work fine since the null issue is beeing checked internally

To provide the same behaviour using the 1st Option you would have to check somehow if its not null first then use the trim() method

if ((text != null) && string.IsNullOrEmpty(text.Trim())) { ... }

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

one of the ways I used it :

protected List<Field> getFieldsWithJsonView(Class sourceClass, Class jsonViewName){
    List<Field> fields = new ArrayList<>();
    for (Field field : sourceClass.getDeclaredFields()) {
        JsonView jsonViewAnnotation = field.getDeclaredAnnotation(JsonView.class);
        if(jsonViewAnnotation!=null){
            boolean jsonViewPresent = false;
            Class[] viewNames = jsonViewAnnotation.value();
            if(jsonViewName!=null && Arrays.asList(viewNames).contains(jsonViewName) ){
                fields.add(field);
            }
        }
    }
    return fields;
}    

You can get the path programmatically:

using System.Configuration;  // Add a reference to System.Configuration.dll
...
var path = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal).FilePath;

Using ES6 features

function checkIfDuplicateExists(w){
    return new Set(w).size !== w.length 
}

console.log(
    checkIfDuplicateExists(["a", "b", "c", "a"])
// true
);

console.log(
    checkIfDuplicateExists(["a", "b", "c"]))
//false

Globally install Composer on OS X 10.11 El Capitan

This command will NOT work in OS X 10.11:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/bin --filename=composer 

Instead, let's write to the /usr/local/bin path for the user:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Now we can access the composer command globally, just like before.

If you are in Javascript already, couldn't you just use Date.Parse() to validate a date instead of using regEx.

RegEx for date is actually unwieldy and hard to get right especially with leap years and all.

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

Depends on what you mean by "html." The most complex case would be complete web pages. That's also the easiest to handle, since you can use a text-mode web browser. See the Wikipedia article listing web browsers, including text mode browsers. Lynx is probably the best known, but one of the others may be better for your needs.

Delete(postion);

Here is a sample project for a soft keyboard.

https://developer.android.com/guide/topics/text/creating-input-method.html

Your's should be in the same lines with a different layout.

Edit: If you need the keyboard only in your application, its very simple! Create a linear layout with vertical orientation, and create 3 linear layouts inside it with horizontal orientation. Then place the buttons of each row in each of those horizontal linear layouts, and assign the weight property to the buttons. Use android:layout_weight=1 for all of them, so they get equally spaced.

This will solve. If you didn't get what was expected, please post the code here, and we are here to help you!

Check out Android Documentation Managing Virtual Devices

there is a way to do this. you have to create a Bitmap and a Canvas and call view.draw(canvas);

here is the code:

public static Bitmap loadBitmapFromView(View v) {
    Bitmap b = Bitmap.createBitmap( v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888);                
    Canvas c = new Canvas(b);
    v.layout(v.getLeft(), v.getTop(), v.getRight(), v.getBottom());
    v.draw(c);
    return b;
}

if the view wasn't displayed before the size of it will be zero. Its possible to measure it like this:

if (v.getMeasuredHeight() <= 0) {
    v.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    Bitmap b = Bitmap.createBitmap(v.getMeasuredWidth(), v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    v.draw(c);
    return b;
}

EDIT: according to this post, Passing WRAP_CONTENT as value to makeMeasureSpec() doesn't to do any good (although for some view classes it does work), and the recommended method is:

// Either this
int specWidth = MeasureSpec.makeMeasureSpec(parentWidth, MeasureSpec.AT_MOST);
// Or this
int specWidth = MeasureSpec.makeMeasureSpec(0 /* any */, MeasureSpec.UNSPECIFIED);
view.measure(specWidth, specWidth);
int questionWidth = view.getMeasuredWidth();

The two syntaxes for stubbing are roughly equivalent. However, you can always use doReturn/when for stubbing; but there are cases where you can't use when/thenReturn. Stubbing void methods is one such. Others include use with Mockito spies, and stubbing the same method more than once.

One thing that when/thenReturn gives you, that doReturn/when doesn't, is type-checking of the value that you're returning, at compile time. However, I believe this is of almost no value - if you've got the type wrong, you'll find out as soon as you run your test.

I strongly recommend only using doReturn/when. There is no point in learning two syntaxes when one will do.

You may wish to refer to my answer at Forming Mockito "grammars" - a more detailed answer to a very closely related question.

You can do it using foreach loop.

          $arrayVal = array(1,2,3,1,2,3,1,2,3,4,4,5,6,4,5,6,88);
          $set_array = array();
          foreach ($array as $value) {
            $set_array[$value]++;
          }
           print_r($set_array);

Output :-

  Array( [1] => 3
             [2] => 3
             [3] => 3
             [4] => 3
             [5] => 2
             [6] => 2
             [88] => 1
            )

I had the same problem, what I did was add a new ComboBox with just the value in the same index then the first one, and then when I change the principal combo the index in the second one change at same time, then I take the value of the second combo and use it.

This is the code:

public Form1()
{
    eventos = cliente.GetEventsTypes(usuario);

    foreach (EventNo no in eventos)
    {
        cboEventos.Items.Add(no.eventno.ToString() + "--" +no.description.ToString());
        cboEventos2.Items.Add(no.eventno.ToString());
    }
}

private void lista_SelectedIndexChanged(object sender, EventArgs e)
{
    lista2.Items.Add(lista.SelectedItem.ToString());
}

private void cboEventos_SelectedIndexChanged(object sender, EventArgs e)
{
    cboEventos2.SelectedIndex = cboEventos.SelectedIndex;
}

Here is a quickly hacked up version of this using SVG I just did. Works well for me on my iPhone. Also works in a desktop browser using normal mouse events.

Use:

$date = date('m/d/Y h:i:s a', time());

It works.

A JavaScript function must first be made that holds what you want to be done:

function print() { console.log("Hello World!") }

and then that function must be called in the onClick method from inside an element:

<a onClick="print()"> ... </a>

You can learn more about modal interactions directly from the Bootstrap 3 documentation found here: http://getbootstrap.com/javascript/#modals

Your modal bind is also incorrect. It should be something like this, where "myModal" = ID of element:

$('#myModal').modal(options)

In other words, if you truly want to keep what you already have, put a "#" in front GSCCModal and see if that works.

It is also not very wise to have an onClick bound to a div element; something like a button would be more suitable.

Hope this helps!

For @return tag use {{field1: Number, field2: String}}, see: http://wiki.servoy.com/display/public/DOCS/Annotating+JavaScript+using+JSDoc

• Add the jar file to your WEB-INF/lib folder.
• Right-click your project in Eclipse, and go to "Build Path > Configure Build Path"
• Add the "Web App Libraries" library

This will ensure all WEB-INF/lib jars are included on the classpath.

In C# Predicates are simply delegates that return booleans. They're useful (in my experience) when you're searching through a collection of objects and want something specific.

I've recently run into them in using 3rd party web controls (like treeviews) so when I need to find a node within a tree, I use the .Find() method and pass a predicate that will return the specific node I'm looking for. In your example, if 'a' mod 2 is 0, the delegate will return true. Granted, when I'm looking for a node in a treeview, I compare it's name, text and value properties for a match. When the delegate finds a match, it returns the specific node I was looking for.

Presumably you mean heap from a memory allocation point of view, not from a data structure point of view (the term has multiple meanings).

A very simple explanation is that the heap is the portion of memory where dynamically allocated memory resides (i.e. memory allocated via malloc). Memory allocated from the heap will remain allocated until one of the following occurs:

1. The memory is free'd
2. The program terminates

If all references to allocated memory are lost (e.g. you don't store a pointer to it anymore), you have what is called a memory leak. This is where the memory has still been allocated, but you have no easy way of accessing it anymore. Leaked memory cannot be reclaimed for future memory allocations, but when the program ends the memory will be free'd up by the operating system.

Contrast this with stack memory which is where local variables (those defined within a method) live. Memory allocated on the stack generally only lives until the function returns (there are some exceptions to this, e.g. static local variables).

You can find more information about the heap in this article.

Is sku just a property of the Product model? If so:

$products = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();

foreach ($products as $product ) {
  // Access $product->sku here...
}

Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

In case of Java 8 we can also use IntStream to reverse the array of integers as:

int[] sample = new int[]{1,2,3,4,5};
int size = sample.length;
int[] reverseSample = IntStream.range(0,size).map(i -> sample[size-i-1])
                      .toArray(); //Output: [5, 4, 3, 2, 1]

Let's finally take a look at the source of the problem

The checkboxes are rendered using images (one may set custom ones via CSS). Here is an (unchecked) checkbox in FireFox, highlighted with DOM inspector:

And here's the same unstyled checkbox in Chrome:

You can see the margin (orange); padding is not present (would be shown green). So what's this pseudo-margin on the right and on the bottom of the checkbox? These are parts of the image used for the checkbox. That's why using just vertical-align: middle doesn't really suffice and that's the source of the cross-browser problems.

So what can we do about this?

One obvious option is – replace the images! Fortunately, one can do this via CSS and replace those with external images, base64 (in-CSS) images, in-CSS svg or just pseudo-elements. It's a robust (cross-browser!) approach, and here's an example of such adjustment stolen from this question:

.checkbox-custom {_x000D_
  opacity: 0;_x000D_
  position: absolute;_x000D_
}_x000D_
.checkbox-custom,_x000D_
.checkbox-custom-label {_x000D_
  display: inline-block;_x000D_
  vertical-align: middle;_x000D_
  margin: 5px;_x000D_
  cursor: pointer;_x000D_
}_x000D_
.checkbox-custom + .checkbox-custom-label:before {_x000D_

Ok, still what about no-custom-images-or-pseudo-elements solution?

TL;DR: looks like this won't work, use custom checkbox instead

First, let's notice that if in other browsers those pseudo-margins inside checkbox icon were arbitrary, there were no consistent solution. To build one, we have to explore the anatomy of such images in existing browsers.

So what browsers do have the pseudo-margins in checkboxes? I've checked out Chrome 75, Vivaldi 2.5 (Chromium-based), FireFox 54 (don't ask why such outdated), IE 11, Edge 42, Safari ?? (borrowed one for a minute, forgot to check out the version). Only Chrome and Vivaldi has such pseudo-margins (I suspect all Chromium-based browsers as well, like Opera).

What's the size of those pseudo-margins? To figure this out one can use a zoomed checkbox:

input {_x000D_
  zoom: 10;_x000D_
  box-shadow: 0 0 1px inset #999;_x000D_
}

<input type=checkbox>

my result is ~7% of width/height and hence 0.9-1.0px in absolute units. The accuracy may be questioned, though: try different values of zoom for the checkbox. In my tests in both Chrome and Vivaldi the relative size of the pseudo-margin is very different at zoom values 10, 20 and at values 11-19 (??):

scale seems to be more consistent:

input {_x000D_
  transform: scale(10) translate(50%, 50%);_x000D_
  box-shadow: 0 0 1px inset #999;_x000D_
}

<input type=checkbox>

so probably ~14% and 2px are the correct values.

Now that we know (?) the size of the pseudo-margin, let's note this is not enough. Are the sizes of the checkbox icons the same for all browsers? Alas! Here's what DOM inspector shows for unstyled checkboxes:

• FireFox: 13.3px
• Chromium-based: 12.8px for the whole thing, hence 12.8 (100% - 14%) = 11px for what is visually perceived as checkbox
• IE 11, Edge: 13px
• Safari: n/a (these should be compared on the same screen, I believe)

Now before we discuss any solutions or tricks, let's ask: what is a correct alignment? What are we trying to achieve? To certain point it's a matter of taste, but basically I can think of the following "nice" alignments' aspects:

text and checkbox on the same baseline (I deliberately don't adjust checkbox size here):

or have same middle line in terms of lowercase letters:

or same middle line in terms of capital letters (it's easier to see the difference for different font size):

and also we have to decide whether the size of the checkbox should be equal to the height of a lowercase letter, a capital letter or something else (bigger, smaller or between lowercase and capital).

For this discussion let's call an alignment nice if the checkbox is on the same baseline as the text and has the size of a capital letter (a highly arguable choice):

Now what tools do we have to:

1. adjust checkbox size
2. recognize Chromium with its pseudo-margined checkbox and set specific styles
3. adjust checkbox/label vertical alignment

?

1. Regarding the checkbox size adjustment: there are width, height, size, zoom, scale (have I missed something?). zoom and scale don't allow to set absolute size, so they may help only with adjusting to text size, not set cross-browser size (unless we can write browser-specific rules). size doesn't work with Chrome (did it work with old IE? anyway, it's not that interesting). width and height work in Chrome and other browsers, so we can set a common size, but again, in Chrome it sets the size of the whole image, not the checkbox itself. Note: it is minimum(width, height) which defines a checkbox's size (if width ? height, the area outside checkbox square is added to "pseudo-margin").

   An unfortunate thing is, the pseudo-margins in Chrome checkbox are not set to zero for any width and heights, as far as I can see.

2. I'm afraid there's no reliable CSS-only method these days.

3. Let's consider vertical alignment. vertical-align can't give consistent results when set to middle or baseline because of the Chrome's pseudo-margin, the only real option to get the same "coordinate system" for all the browsers is to align label and input to the top:

   

   (on the picture: vertical-align: top, bottom and bottom without box-shadow)

So what result do we get from this?

input[type="checkbox"] {_x000D_
    height: 0.95em;_x000D_
    width: 0.95em;_x000D_
}_x000D_
label, input {_x000D_
    vertical-align: top;_x000D_
}

<label><input type="checkbox">label</label>

The snippet above works with Chrome (Chromium-based browsers), but other browsers require a smaller size of the checkbox. It seems to be impossible to adjust both the size and vertical alignment in a way that works around Chromium's checkbox image quirk. My final suggestion is: use custom checkboxes instead – and you'll avoid frustration :)

The 00947 message indicates that the record which you are trying to send to Oracle lacks one or more of the columns which was included at the time the table was created. The 00913 message indicates that the record which you are trying to send to Oracle includes more columns than were included at the time the table was created. You just need to check the number of columns and its type in both the tables ie the tables that are involved in the sql.

For me setting the execution policy to Unrestricted did not work. I had to repair the vs2013 installation by going into Control Panel. Repairing the installation worked for me.

This works for me and you don't need the inline script:

Javascript:

    $(document).ready(function() {
    $('.showme').bind('click', function() {

        var id=$(this).attr("id");
        var num=$(this).attr("class");
        var poststr="request="+num+"&moreinfo="+id;
        $.ajax({
              url:"testme.php",
              cache:0,
              data:poststr,
              success:function(result){
                     document.getElementById("stuff").innerHTML=result;
               }
        }); 
    });
 });

HTML:

    <div class='request_1 showme' id='rating_1'>More stuff 1</div>
    <div class='request_2 showme' id='rating_2'>More stuff 2</div>
    <div class='request_3 showme' id='rating_3'>More stuff 3</div>

    <div id="stuff">Here is some stuff that will update when the links above are clicked</div>

The request is sent to testme.php:

    header("Cache-Control: no-cache");
    header("Pragma: nocache");

    $request_id = preg_replace("/[^0-9]/","",$_REQUEST['request']);
    $request_moreinfo = preg_replace("/[^0-9]/","",$_REQUEST['moreinfo']);

    if($request_id=="1")
    {
        echo "show 1";
    }
    elseif($request_id=="2")
    {
        echo "show 2";
    }
    else
    {
        echo "show 3";
    }

Python 3.x for large (but not too large) DataFrames

Maybe because I have an older version of pandas but on Jupyter notebook this work for me

import pandas as pd
from IPython.core.display import HTML

df=pd.read_pickle('Data1')
display(HTML(df.to_html()))

You can use sklearn.utils.shuffle() (requires sklearn 0.16.1 or higher to support Pandas data frames):

# Generate data
import pandas as pd
df = pd.DataFrame({'A':range(5), 'B':range(5)})
print('df: {0}'.format(df))

# Shuffle Pandas data frame
import sklearn.utils
df = sklearn.utils.shuffle(df)
print('\n\ndf: {0}'.format(df))

outputs:

df:    A  B
0  0  0
1  1  1
2  2  2
3  3  3
4  4  4


df:    A  B
1  1  1
0  0  0
3  3  3
4  4  4
2  2  2

Then you can use df.reset_index() to reset the index column, if needs to be:

df = df.reset_index(drop=True)
print('\n\ndf: {0}'.format(df)

outputs:

df:    A  B
0  1  1
1  0  0
2  4  4
3  2  2
4  3  3

this.myService.getConfig().subscribe(
  (res) => console.log(res),
  (err) => console.log(err),
  () => console.log('done!')
);

Not sure how to apply that to your file on your server, but typically, the regex to match the beginning of a string would be :

^CTR

The ^ means beginning of string / line

Easy enough:

sudo aptitude install python3-pip
pip-3.2 install --user pkg

If you want Python 3.3, which isn't the default as of Ubuntu 12.10:

sudo aptitude install python3-pip python3.3
python3.3 -m pip.runner install --user pkg

It looks like you can download just the grid now on Bootstrap 4s new download features.

this way is a bit more flexible than using all():

my_list = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
all_zeros = False if False in [x[2] == 0 for x in my_list] else True
any_zeros = True if True in [x[2] == 0 for x in my_list] else False

or more succinctly:

all_zeros = not False in [x[2] == 0 for x in my_list]
any_zeros = 0 in [x[2] for x in my_list]

Compatibility Guide for JDK 8 says that in Java 8 the command line flag MaxPermSize has been removed. The reason is that the permanent generation was removed from the hotspot heap and was moved to native memory. So in order to remove this message edit MAVEN_OPTS Environment User Variable:

Java 7

MAVEN_OPTS -Xmx512m -XX:MaxPermSize=128m

Java 8

MAVEN_OPTS -Xmx512m

This is the shorter version: Basically I try to get the difference between the post timestamp with the Date() now.

// MARK: - UPDATE Time Stamp
static func updateTimeStampPost(postTimeStamp: Date?, _ completion: (_ finalString: String?) -> Void) {
    // date in the current state
    let date = Date()
    let dateComponentFormatter = DateComponentsFormatter()

    // change the styling date, wether second minute or hour
    dateComponentFormatter.unitsStyle = .abbreviated
    dateComponentFormatter.allowedUnits = [.second, .minute, .hour, .day, .weekOfMonth]
    dateComponentFormatter.maximumUnitCount = 1

    // return the date new format as a string in the completion
    completion(dateComponentFormatter.string(from: postTimeStamp!, to: date))
}

I found this article

  /// <summary>
    /// Creates a new Image containing the same image only rotated
    /// </summary>
    /// <param name=""image"">The <see cref=""System.Drawing.Image"/"> to rotate

    public static Bitmap RotateImage(Image image, PointF offset, float angle)
    {
        if (image == null)
            throw new ArgumentNullException("image");

        //create a new empty bitmap to hold rotated image
        Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
        rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);

        //make a graphics object from the empty bitmap
        Graphics g = Graphics.FromImage(rotatedBmp);

        //Put the rotation point in the center of the image
        g.TranslateTransform(offset.X, offset.Y);

        //rotate the image
        g.RotateTransform(angle);

        //move the image back
        g.TranslateTransform(-offset.X, -offset.Y);

        //draw passed in image onto graphics object
        g.DrawImage(image, new PointF(0, 0));

        return rotatedBmp;
    }

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

Yes, SQL Server 2012 supports multiple inserts - that feature was introduced in SQL Server 2008.

That makes me wonder if you have Management Studio 2012, but you're really connected to a SQL Server 2005 instance ...

What version of the SQL Server engine do you get from SELECT @@VERSION ??

String [] obj = (from c in db.Contacts
                           where c.FirstName.StartsWith(prefixText)
                           select c.FirstName).ToArray();
            return obj;

StartsWith() and EndsWith() can help you a lot here. If you want to find data in between the field, then Contains() can be used.

Um, shouldn't the destructor be calling delete, rather than delete[]?

Depending on how much spacing you need, this might help. That's the only thing remotely related to letter-spacing in the TextView.

Edit: please see @JerabekJakub's response below for an updated, better method to do this starting with api 21 (Lollipop)

My Solution on Windows:

1. Right click at directory to push and select "Git Bash Here".
2. ssh-keygen -t rsa (Press enter for all values)
3. Check terminal for: Your public key has been saved in /c/Users/<your_user_name_here>/.ssh/id_rsa.pub
4. Copy public key from specified file.
5. Go to your GitHub profile => Settings => SSH and GPG keys => New SSH key => Paste your SSH key there => Save

I had been using the method in Jon Skeet's answer, but another one occurred to me using Concat. The Concat method performed slightly better in a limited test, but it's a hassle and I'll probably just stick with Contains, or maybe I'll write a helper method to do this for me. Either way, here's another option if anyone is interested:

The Method

// Given an array of id's
var ids = new Guid[] { ... };

// and a DataContext
var dc = new MyDataContext();

// start the queryable
var query = (
    from thing in dc.Things
    where thing.Id == ids[ 0 ]
    select thing 
);

// then, for each other id
for( var i = 1; i < ids.Count(); i++ ) {
    // select that thing and concat to queryable
    query.Concat(
        from thing in dc.Things
        where thing.Id == ids[ i ]
        select thing
    );
}

Performance Test

This was not remotely scientific. I imagine your database structure and the number of IDs involved in the list would have a significant impact.

I set up a test where I did 100 trials each of Concat and Contains where each trial involved selecting 25 rows specified by a randomized list of primary keys. I've run this about a dozen times, and most times the Concat method comes out 5 - 10% faster, although one time the Contains method won by just a smidgen.

Use ioutil.ReadFile:

func ReadFile(filename string) ([]byte, error)

ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.

You will get a []byte instead of a string. It can be converted if really necessary:

s := string(buf)

Here's a different approach. Create a custom Exception annotated with @ResponseStatus, like the following one.

@ResponseStatus(code = HttpStatus.NOT_FOUND, reason = "Not Found")
public class NotFoundException extends Exception {

    public NotFoundException() {
    }
}

And throw it when needed.

@RequestMapping(value = "/matches/{matchId}", produces = "application/json")
@ResponseBody
public String match(@PathVariable String matchId) {
    String json = matchService.getMatchJson(matchId);
    if (json == null) {
        throw new NotFoundException();
    }
    return json;
}

Check out the Spring documentation here: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-ann-annotated-exceptions.

We have had some fun with the following, interesting to share so:

class RepeatFunction:
    def __init__(self,n=1): self.n = n
    def __call__(self,Func):
        for i in xrange(self.n):
            Func()
        return Func


#----usage
k = 0

@RepeatFunction(7)                       #decorator for repeating function
def Job():
    global k
    print k
    k += 1

print '---------'
Job()

Results:

0
1
2
3
4
5
6
---------
7

Instead of manipulating the CMAKE_CXX_FLAGS strings directly (which could be done more nicely using string(APPEND CMAKE_CXX_FLAGS_DEBUG " -g3") btw), you can use add_compiler_options:

add_compile_options(
  "-Wall" "-Wpedantic" "-Wextra" "-fexceptions"
  "$<$<CONFIG:DEBUG>:-O0;-g3;-ggdb>"
)

This would add the specified warnings to all build types, but only the given debugging flags to the DEBUG build. Note that compile options are stored as a CMake list, which is just a string separating its elements by semicolons ;.

If you use eclipse, maybe PyUML. Haven't used it, though.

If you cannot shell out thousands of dollars for a decent Mac then there is an option to run OSX and XCode in the cloud:

A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:

.clear {     height: 50px;     width: 25px; } 

Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both; attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:

.clear {     clear: both; } 

I changed the "debug" to "info" and it worked. Here is what I did:

Before:

log4j.rootLogger=debug, stdout, R

After:

log4j.rootLogger=info, stdout, R 

You have two way for your question :

1- Use Update Command in your Trigger.

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;
    IF UPDATE (QtyToRepair) 
    BEGIN
        UPDATE SCHEDULE 
        SET modified = GETDATE()
           , ModifiedUser = SUSER_NAME()
           , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S INNER JOIN Inserted I 
        ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END 
END

2- Use Join between Inserted table and deleted table

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;    

    UPDATE SCHEDULE 
    SET modified = GETDATE()
       , ModifiedUser = SUSER_NAME()
       , ModifiedHost = HOST_NAME()
    FROM SCHEDULE S 
    INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
    INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber                  
    WHERE S.QtyToRepair <> I.QtyToRepair
    AND D.QtyToRepair <> I.QtyToRepair
END

When you use update command for table SCHEDULE and Set QtyToRepair Column to new value, if new value equal to old value in one or multi row, solution 1 update all updated row in Schedule table but solution 2 update only schedule rows that old value not equal to new value.

Left Click on the WAMP icon the system try -> PHP -> PHP Extensions -> Enable php_curl

For setting value in hidden field do in the following way:

@Html.HiddenFor(model => model.title, 
                new { id= "natureOfVisitField", Value = @Model.title})

It will work

The "netstat --programs" command will give you the process information, assuming you're the root user. Then you will have to kill the "offending" process which may well start up again just to annoy you.

Depending on what you're actually trying to achieve, solutions to that problem will vary based on the processes holding those ports. For example, you may need to disable services (assuming they're unneeded) or configure them to use a different port (if you do need them but you need that port more).

Update MyTable
Set Value = (
                Select Min( T2.Value )
                From MyTable As T2
                Where T2.Id <> MyTable.Id
                    And T2.Name = MyTable.Name
                )
Where ( Value Is Null Or Value = '' )
    And Exists  (
                Select 1
                From MyTable As T3
                Where T3.Id <> MyTable.Id
                    And T3.Name = MyTable.Name
                )

Try to login via the terminal using the following command:

mysql -u root -p

It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:

database_password: "0000"

A DIV is by default a BLOCK display element, meaning it sits on its own line. If you add the CSS property display:inline it will behave the way you want. But perhaps you should be considering a SPAN instead?

In Java side, the date is usually represented by the (poorly designed, but that aside) java.util.Date. It is basically backed by the Epoch time in flavor of a long, also known as a timestamp. It contains information about both the date and time parts. In Java, the precision is in milliseconds.

In SQL side, there are several standard date and time types, DATE, TIME and TIMESTAMP (at some DB's also called DATETIME), which are represented in JDBC as java.sql.Date, java.sql.Time and java.sql.Timestamp, all subclasses of java.util.Date. The precision is DB dependent, often in milliseconds like Java, but it can also be in seconds.

In contrary to java.util.Date, the java.sql.Date contains only information about the date part (year, month, day). The Time contains only information about the time part (hours, minutes, seconds) and the Timestamp contains information about the both parts, like as java.util.Date does.

The normal practice to store a timestamp in the DB (thus, java.util.Date in Java side and java.sql.Timestamp in JDBC side) is to use PreparedStatement#setTimestamp().

java.util.Date date = getItSomehow();
Timestamp timestamp = new Timestamp(date.getTime());
preparedStatement = connection.prepareStatement("SELECT * FROM tbl WHERE ts > ?");
preparedStatement.setTimestamp(1, timestamp);

The normal practice to obtain a timestamp from the DB is to use ResultSet#getTimestamp().

Timestamp timestamp = resultSet.getTimestamp("ts");
java.util.Date date = timestamp; // You can just upcast.

If the variance of the input is statistically distributed (e.g. normal, log-normal, etc.) then reservoir sampling is a reasonable way of estimating percentiles/medians from an arbitrarily long stream of numbers.

int n = 0;  // Running count of elements observed so far  
#define SIZE 10000
int reservoir[SIZE];  

while(streamHasData())
{
  int x = readNumberFromStream();

  if (n < SIZE)
  {
       reservoir[n++] = x;
  }         
  else 
  {
      int p = random(++n); // Choose a random number 0 >= p < n
      if (p < SIZE)
      {
           reservoir[p] = x;
      }
  }
}

"reservoir" is then a running, uniform (fair), sample of all input - regardless of size. Finding the median (or any percentile) is then a straight-forward matter of sorting the reservoir and polling the interesting point.

Since the reservoir is fixed size, the sort can be considered to be effectively O(1) - and this method runs with both constant time and memory consumption.

Personally, for me, the best solution for a similar issue was:

HTML

<input type="radio" name="selectAll" value="true" />
<input type="radio" name="selectAll" value="false" />

JQuery

var $selectAll = $( "input:radio[name=selectAll]" );
    $selectAll.on( "change", function() {
         console.log( "selectAll: " + $(this).val() );
         // or
         alert( "selectAll: " + $(this).val() );
    });

*The event "click" can work in place of "change" as well.

Hope this helps!

Because you are choosing jre dir. and not JDK dir. JDK dir. is for instance (depending on update and whether it's 64 bit or 32 bit): C:\Program Files (x86)\Java\jdk1.7.0_45 In my case it's 32 bit JDK 1.7 update 45

Instead of any Array you can load your data in DataTable like:

using System.Data;

DataTable dt = new DataTable();
using (var con = new SqlConnection("Data Source=local;Initial Catalog=Test;Integrated Security=True"))
{
    using (var command = new SqlCommand("SELECT col1,col2" +
    {
        con.Open();
        using (SqlDataReader dr = command.ExecuteReader())
        {
            dt.Load(dr);
        }
    }
}

You can also use SqlDataAdapater to fill your DataTable like

SqlDataAdapter da = new SqlDataAdapter(command);
da.Fill(dt);

Later you can iterate each row and compare like:

foreach (DataRow dr in dt.Rows)
{
    if (dr.Field<string>("col1") == "yourvalue") //your condition
    {
    }
}

TypeScript has Map. You can use like:

public myMap = new Map<K,V>([
[k1, v1],
[k2, v2]
]);

myMap.get(key); // returns value
myMap.set(key, value); // import a new data
myMap.has(key); // check data

You can use URLConnection with setDoOutput(true), getOutputStream() (for sending data), and getInputStream() (for receiving). Sun has an example for exactly this.

In my case this was happening a lot in my development and test environments. After trying all of the above solutions without any success I found that I was able to fix this problem by deleting all session cookies. The web developer extension makes this very easy to do. I mostly use Firefox for testing and development, but this also happened while testing in Chrome. The fix also worked in Chrome.

I haven't had to do this yet in the production environment and have not received any reports of people not being able to log in. This also only seemed to happen after making the session cookies to be secure. It never happened in the past when they were not secure.

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Result:

"Hello, this is Mike"

The difference is an iframe is able to "float" within content in a page, that is you can create an html page and position an iframe within it. This allows you to have a page and place another document directly in it. A frameset allows you to split the screen into different pages (horizontally and vertically) and display different documents in each part.

Memory mapping has a potential for a huge speed advantage compared to traditional IO. It lets the operating system read the data from the source file as the pages in the memory mapped file are touched. This works by creating faulting pages, which the OS detects and then the OS loads the corresponding data from the file automatically.

This works the same way as the paging mechanism and is usually optimized for high speed I/O by reading data on system page boundaries and sizes (usually 4K) - a size for which most file system caches are optimized to.

It looks like you would do something like this:

boost::shared_mutex _access;
void reader()
{
  // get shared access
  boost::shared_lock<boost::shared_mutex> lock(_access);

  // now we have shared access
}

void writer()
{
  // get upgradable access
  boost::upgrade_lock<boost::shared_mutex> lock(_access);

  // get exclusive access
  boost::upgrade_to_unique_lock<boost::shared_mutex> uniqueLock(lock);
  // now we have exclusive access
}

I figured it out. The problem was that there were still some pages in the project that hadn't been converted to use "namespaces" as needed in a web application project. I guess I thought that it wouldn't compile if there were still any of those pages around, but if the page didn't reference anything from outside itself it didn't appear to squawk. So when it was saying that it didn't inherit from "System.Web.UI.Page" that was because it couldn't actually find the class "BasePage" at run time because the page itself was not in the WebApplication namespace. I went through all my pages one by one and made sure that they were properly added to the WebApplication namespace and now it not only compiles without issue, it also displays normally. yay!

what a trial converting from website to web application project can be!

Is your SQL Server in 'mixed mode authentication' ? This is necessary to login with a SQL server account instead of a Windows login.

You can verify this by checking the properties of the server and then SECURITY, it should be in 'SQL Server and Windows Authentication Mode'

This problem occurs if the user tries to log in with credentials that cannot be validated. This problem can occur in the following scenarios:

Scenario 1: The login may be a SQL Server login but the server only accepts Windows Authentication.

Scenario 2: You are trying to connect by using SQL Server Authentication but the login used does not exist on SQL Server.

Scenario 3: The login may use Windows Authentication but the login is an unrecognized Windows principal. An unrecognized Windows principal means that Windows can't verify the login. This might be because the Windows login is from an untrusted domain.

It's also possible the user put in incorrect information.

To hide errors only from users but displaying logs errors in apache log

error_reporting(E_ALL);
ini_set('display_errors', 0);

1 - Displaying error only in log
2 - hide from users

Most elegant solution: works for any @DATE

DAY(DATEADD(DD,-1,DATEADD(MM,DATEDIFF(MM,-1,@DATE),0)))

Throw it in a function or just use it inline. This answers the original question without all the extra junk in the other answers.

examples for dates from other answers:

SELECT DAY(DATEADD(DD,-1,DATEADD(MM,DATEDIFF(MM,-1,'1/31/2009'),0))) Returns 31

SELECT DAY(DATEADD(DD,-1,DATEADD(MM,DATEDIFF(MM,-1,'2404-feb-15'),0))) Returns 29

SELECT DAY(DATEADD(DD,-1,DATEADD(MM,DATEDIFF(MM,-1,'2011-12-22'),0))) Returns 31

just add android:gravity="right" in your Liner Layout.

var emailRegex = /^[A-Z0-9_'%=+!`#~$*?^{}&|-]+([\.][A-Z0-9_'%=+!`#~$*?^{}&|-]+)*@[A-Z0-9-]+(\.[A-Z0-9-]+)+$/i;
if(emailRegex.test('yoursamplemail'))
alert('valid');
else
alert('invalid');

Tip #2

Can't you use the classical 2> redirection operator.

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) 2> $NULL
if(!$?){
   'foo'
}

I don't like errors so I avoid them at all costs.

You can you use subprocess to achieve this.

import subprocess

#This command could have multiple commands separated by a new line \n
some_command = "export PATH=$PATH://server.sample.mo/app/bin \n customupload abc.txt"

p = subprocess.Popen(some_command, stdout=subprocess.PIPE, shell=True)

(output, err) = p.communicate()  

#This makes the wait possible
p_status = p.wait()

#This will give you the output of the command being executed
print "Command output: " + output

iOS 10 update

The ban on autoplay has been lifted as of iOS 10 - but with some restrictions (e.g. A can be autoplayed if there is no audio track).

To see a full list of these restrictions, see the official docs: https://webkit.org/blog/6784/new-video-policies-for-ios/

iOS 9 and before

As of iOS 6.1, it is no longer possible to auto-play videos on the iPad.

My assumption as to why they've disabled the auto-play feature?

Well, as many device owners have data usage/bandwidth limits on their devices, I think Apple felt that the user themselves should decide when they initiate bandwidth usage.

After a bit of research I found the following extract in the Apple documentation in regard to auto-play on iOS devices to confirm my assumption:

"Apple has made the decision to disable the automatic playing of video on iOS devices, through both script and attribute implementations.

In Safari, on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and auto-play are disabled. No data is loaded until the user initiates it." - Apple documentation.

Here is a separate warning featured on the Safari HTML5 Reference page about why embedded media cannot be played in Safari on iOS:

Warning: To prevent unsolicited downloads over cellular networks at the user’s expense, embedded media cannot be played automatically in Safari on iOS—the user always initiates playback. A controller is automatically supplied on iPhone or iPod touch once playback in initiated, but for iPad you must either set the controls attribute or provide a controller using JavaScript.

What this means (in terms of code) is that Javascript's play() and load() methods are inactive until the user initiates playback, unless the play() or load() method is triggered by user action (e.g. a click event).

Basically, a user-initiated play button works, but an onLoad="play()" event does not.

For example, this would play the movie:

<input type="button" value="Play" onclick="document.myMovie.play()">

Whereas the following would do nothing on iOS:

<body onload="document.myMovie.play()">

For people that come here that are just trying to get the repository but don't care about the protocol (ssh / https), you might just want to use https instead of ssh (if it's supported).

So for example you use

git clone https://github.com/%REPOSITORYFOLDER%/%REPOSITORYNAME%.git

instead of

git clone [email protected]:%REPOSITORYFOLDER%/%REPOSITORYNAME%.git

Right. So I've finally got to the bottom of the problem: it was a botched in-place OTA upgrade.

My suspicions intensified after my Garmin Fenix 2 wasn't able to connect via bluetooth and after googling "Marshmallow upgrade issues". Anyway, a "Factory reset" fixed the issue.

Surprisingly, the reset did not return the phone to the original Kitkat; instead, the wipe process picked up the OTA downloaded 6.0 upgrade package and ran with it, resulting (I guess) in a "cleaner" upgrade.

Of course, this meant that the phone lost all the apps that I'd installed. But, freshly installed apps, including mine, work without any changes (i.e. there is backward compatibility). Whew!

Use the <button> tag instead. <button> labels are vertically centered by default.

Try to save the file before, then it will indent.

You have to use:

abs() for int
fabs() for double
fabsf() for float

Above function will also work but you can also try something like this.

    if(a<0)
    {
         a=-a;
    }

When to use each

@staticmethod function is nothing more than a function defined inside a class. It is callable without instantiating the class first. It’s definition is immutable via inheritance.

• Python does not have to instantiate a bound-method for object.
• It eases the readability of the code: seeing @staticmethod, we know that the method does not depend on the state of object itself;

@classmethod function also callable without instantiating the class, but its definition follows Sub class, not Parent class, via inheritance, can be overridden by subclass. That’s because the first argument for @classmethod function must always be cls (class).

• Factory methods, that are used to create an instance for a class using for example some sort of pre-processing.
• Static methods calling static methods: if you split a static methods in several static methods, you shouldn't hard-code the class name but use class methods

here is good link to this topic.

for your example:

{'profiles': [{'name':'john', 'age': 44}, {'name':'Alex','age':11}]}

you will have to do something of this effect:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

this returns the array object.

Then iterating will be as follows:

    int size = the_json_array.length();
    ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
    for (int i = 0; i < size; i++) {
        JSONObject another_json_object = the_json_array.getJSONObject(i);
            //Blah blah blah...
            arrays.add(another_json_object);
    }

//Finally
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

//The end...

You will have to determine if the data is an array (simply checking that charAt(0) starts with [ character).

Hope this helps.

Doing the same with python 3.x, where raw_input() doesn't exist:

def ask(question, default = None):
    hasDefault = default is not None
    prompt = (question 
               + " [" + ["y", "Y"][hasDefault and default] + "/" 
               + ["n", "N"][hasDefault and not default] + "] ")

    while True:
        sys.stdout.write(prompt)
        choice = input().strip().lower()
        if choice == '':
            if default is not None:
                return default
        else:
            if "yes".startswith(choice):
                return True
            if "no".startswith(choice):
                return False

        sys.stdout.write("Please respond with 'yes' or 'no' "
                             "(or 'y' or 'n').\n")

If you're trying to open a scala/sbt project, the sbt version set in /project/build.properties must match the sbt version installed on your system or intellij won't detect your project's modules properly.

Once that's done, you can just delete the idea folder and restart as the other answers suggest.

You can parse the date using the Date constructor, then spit out the individual time components:

function convert(str) {_x000D_
  var date = new Date(str),_x000D_
    mnth = ("0" + (date.getMonth() + 1)).slice(-2),_x000D_
    day = ("0" + date.getDate()).slice(-2);_x000D_
  return [date.getFullYear(), mnth, day].join("-");_x000D_
}_x000D_
_x000D_
console.log(convert("Thu Jun 09 2011 00:00:00 GMT+0530 (India Standard Time)"))_x000D_
//-> "2011-06-08"

As you can see from the result though, this will parse the date into the local time zone. If you want to keep the date based on the original time zone, the easiest approach is to split the string and extract the parts you need:

function convert(str) {_x000D_
  var mnths = {_x000D_
      Jan: "01",_x000D_
      Feb: "02",_x000D_
      Mar: "03",_x000D_
      Apr: "04",_x000D_
      May: "05",_x000D_
      Jun: "06",_x000D_
      Jul: "07",_x000D_
      Aug: "08",_x000D_
      Sep: "09",_x000D_
      Oct: "10",_x000D_
      Nov: "11",_x000D_
      Dec: "12"_x000D_
    },_x000D_
    date = str.split(" ");_x000D_
_x000D_
  return [date[3], mnths[date[1]], date[2]].join("-");_x000D_
}_x000D_
_x000D_
console.log(convert("Thu Jun 09 2011 00:00:00 GMT+0530 (India Standard Time)"))_x000D_
//-> "2011-06-09"

Try This,

alter session set "_convert_set_to_join"= true;

The other alternative is to rewrite the SQL query manually [replacing the minus operator with a NOT IN subquery] evidences about 30% improvement in execution time .

 select * 
   from A 
    where (col1,col2,?) not in 
   (select col1,col2,? from B) 
   union all 
   select * from B 
  where (col1,col2,?) not in 
  (select col1,col2,? from A); 

I have referred from this post click here

These answers didn't work for me. I had to use the following:

import subprocess
p = subprocess.Popen(["pwd"], stdout=subprocess.PIPE)
out = p.stdout.read()
print out

Or as a function (using shell=True was required for me on Python 2.6.7 and check_output was not added until 2.7, making it unusable here):

def system_call(command):
    p = subprocess.Popen([command], stdout=subprocess.PIPE, shell=True)
    return p.stdout.read()

This code sample can be used to change date format. Here I want to change from yyyy-MM-dd to dd-MM-yyyy. Here pos is position of column.

The problem is that you do not have bzip2 installed. The tar program relies upon this external program to do compression. For installing bzip2, it depends on the system you are using. For example, with Ubuntu that would be on Ubuntu

sudo apt-get install bzip2

The GNU tar program does not know how to compress an existing file such as user-logs.tar (bzip2 does that). The tar program can use external compression programs gzip, bzip2, xz by opening a pipe to those programs, sending a tar archive via the pipe to the compression utility, which compresses the data which it reads from tar and writes the result to the filename which the tar program specifies.

Alternatively, the tar and compression utility could be the same program. BSD tar does its compression using lib archive (they're not really distinct except in name).

You could use the 'isActive' prop like so:

const { router } = this.context;
if (router.isActive('/login')) {
    router.push('/');
}

isActive will return a true or false.

Tested with react-router 2.7

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

If you're open to using AWK:

awk '/textstring/ {print FNR}' textfile

In this case, FNR is the line number. AWK is a great tool when you're looking at grep|cut, or any time you're looking to take grep output and manipulate it.

As someone more experienced with Oracle DB, I was concerned about this limit too. I carried out a performance test for a query with ~10'000 parameters in an IN-list, fetching prime numbers up to 100'000 from a table with the first 100'000 integers by actually listing all the prime numbers as query parameters.

My results indicate that you need not worry about overloading the query plan optimizer or getting plans without index usage, since it will transform the query to use = ANY({...}::integer[]) where it can leverage indices as expected:

-- prepare statement, runs instantaneous:
PREPARE hugeplan (integer, integer, integer, ...) AS
SELECT *
FROM primes
WHERE n IN ($1, $2, $3, ..., $9592);

-- fetch the prime numbers:
EXECUTE hugeplan(2, 3, 5, ..., 99991);

-- EXPLAIN ANALYZE output for the EXECUTE:
"Index Scan using n_idx on primes  (cost=0.42..9750.77 rows=9592 width=5) (actual time=0.024..15.268 rows=9592 loops=1)"
"  Index Cond: (n = ANY ('{2,3,5,7, (...)"
"Execution time: 16.063 ms"

-- setup, should you care:
CREATE TABLE public.primes
(
  n integer NOT NULL,
  prime boolean,
  CONSTRAINT n_idx PRIMARY KEY (n)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE public.primes
  OWNER TO postgres;

INSERT INTO public.primes
SELECT generate_series(1,100000);

However, this (rather old) thread on the pgsql-hackers mailing list indicates that there is still a non-negligible cost in planning such queries, so take my word with a grain of salt.

You'll want to use the WHERE EXISTS syntax instead.

SELECT *
FROM table1
WHERE EXISTS (SELECT *
              FROM table2
              WHERE Lead_Key = @Lead_Key
                        AND table1.CM_PLAN_ID = table2.CM_PLAN_ID
                        AND table1.Individual_ID = table2.Individual_ID)

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

Give the textbox an id of "txtValue" and change the input button declaration to the following:

<input type="button" value="submit" onclick="verifyorder(document.getElementById('txtValue').value)" />

read will return bytes. At least for Python 3, if you want to return a string, you have to decode using the right encoding:

import boto3

s3 = boto3.resource('s3')

obj = s3.Object(bucket, key)
obj.get()['Body'].read().decode('utf-8') 

I Feel Eclipse IDE is more suitable for android applications rather than other IDEs. Because its providing us more than five perspectives which will make our project flexible and ease.You may try Eclipse ides starts with 3.6 and above will provide you better performance.

Eclipse_jee_indigo
Eclipse_java_indigo
Eclipse_classic

The above eclipses are belongs to the version3.7.2 which are all latest and supports all kind of access.

You could use %in% like this:

df[, !(colnames(df) %in% c("x","bar","foo"))]

I've refactored @Academy of Programmer's answer to shorter code and altered it so that it only hits https:// URLs:

    public static string GetExternalIPAddress()
    {
        string result = string.Empty;

        string[] checkIPUrl =
        {
            "https://ipinfo.io/ip",
            "https://checkip.amazonaws.com/",
            "https://api.ipify.org",
            "https://icanhazip.com",
            "https://wtfismyip.com/text"
        };

        using (var client = new WebClient())
        {
            client.Headers["User-Agent"] = "Mozilla/4.0 (Compatible; Windows NT 5.1; MSIE 6.0) " +
                "(compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

            foreach (var url in checkIPUrl)
            {
                try
                {
                    result = client.DownloadString(url);
                }
                catch
                {
                }

                if (!string.IsNullOrEmpty(result))
                    break;
            }
        }

        return result.Replace("\n", "").Trim();
    }
}

From other post:

    find /c "string" file >NUL
    if %errorlevel% equ 1 goto notfound
        echo found
    goto done
    :notfound
        echo notfound
    goto done
    :done

Use the /i switch when you want case insensitive checking:

    find /i /c "string" file >NUL

Or something like: if not found write to file.

    find /c "%%P" file.txt  || ( echo %%P >> newfile.txt )

Or something like: if found write to file.

    find /c "%%P" file.txt  && ( echo %%P >> newfile.txt )

Or something like:

    find /c "%%P" file.txt  && ( echo found ) || ( echo not found )

That's because you have the Date in American format in line[i] and UK format in the FormatString.

11/20/2011
M / d/yyyy

I'm guessing you might need to change the FormatString to:

"M/d/yyyy h:mm"

This is the best way IMO. No need for properties, or readonly:

public static class Constants
{
   public const string SomeConstant = "Some value";
}

You can do it using xml as well:

<field name="acmeOne" type="string" column="acmeOne" length="36">
    <options>
        <option name="comment">Your SQL field comment goes here.</option>
        <option name="default">Default Value</option>
    </options>
</field>

In linux you can use this commande :

for exemple i want to delete "*.py~" so my command should be ==>

find . -name "*.py~" -exec rm -f {} \;

I was facing a problem like this, and had the idea of simply changing the innerHTML of the problematic object's children.

adiv.innerHTML = "<div...> the original html that js uses </div>";

Seems dirty, but it saved my life, as it works!
