Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

I am in the same situation pointed out by malcook in his comment: unfortunately the answer by Thierry does not work with ggplot2 version 0.9.3.1.

png("figure_%d.png")
set.seed(2014)
library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100),
    x = rnorm(500, mean = rep(1:5, 100)),
    y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

Here it is the first figure:

and the second figure:

As we can see the colors do not stay fixed, for example E switches from magenta to blu.

As suggested by malcook in his comment and by hadley in his comment the code which uses limits works properly:

ggplot(subdata, aes(x = x, y = y, colour = fCategory)) +       
    geom_point() + 
    scale_colour_discrete(drop=TRUE,
        limits = levels(dataset$fCategory))

gives the following figure, which is correct:

I have observed on Windows 2008 the Windows Error Reporting crash dumps get staged in the folder:

C:\Users\All Users\Microsoft\Windows\WER\ReportQueue

Which, starting with Windows Vista, is an alias for:

C:\ProgramData\Microsoft\Windows\WER\ReportQueue

db.query('select * from login',(err, results, fields)=>{
    if(err){
        console.log('error in fetching data')
    }
    var string=JSON.stringify(results);
    console.log(string);
    var json =  JSON.parse(string);
   // to get one value here is the option
    console.log(json[0].name);
})

You have to do this to echo it:

echo $row['note'];

(The data is coming as an array)

I've done it before, I just used:

down.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            return true;
        }
    });

Per documentation:

public void setOnLongClickListener (View.OnLongClickListener l)

Since: API Level 1 Register a callback to be invoked when this view is clicked and held. If this view is not long clickable, it becomes long clickable.

Notice that it requires to return a boolean, this should work.

As I said in comments - you should always use parameters in your query - NEVER EVER concatenate together your SQL statements yourself.

Also: I would recommend to separate the click event handler from the actual code to insert the data.

So I would rewrite your code to be something like

In your web page's code-behind file (yourpage.aspx.cs)

private void button1_Click(object sender, EventArgs e)
{
      string connectionString = "Data Source=DELL-PC;initial catalog=AdventureWorks2008R2 ; User ID=sa;Password=sqlpass;Integrated Security=SSPI;";

      InsertData(connectionString,
                 textBox1.Text.Trim(),  -- first name
                 textBox2.Text.Trim(),  -- last name
                 textBox3.Text.Trim(),  -- user name
                 textBox4.Text.Trim(),  -- password
                 Convert.ToInt32(comboBox1.Text),  -- age
                 comboBox2.Text.Trim(), -- gender
                 textBox7.Text.Trim() );  -- contact
}

In some other code (e.g. a databaselayer.cs):

private void InsertData(string connectionString, string firstName, string lastname, string username, string password
                        int Age, string gender, string contact)
{
    // define INSERT query with parameters
    string query = "INSERT INTO dbo.regist (FirstName, Lastname, Username, Password, Age, Gender,Contact) " + 
                   "VALUES (@FirstName, @Lastname, @Username, @Password, @Age, @Gender, @Contact) ";

    // create connection and command
    using(SqlConnection cn = new SqlConnection(connectionString))
    using(SqlCommand cmd = new SqlCommand(query, cn))
    {
        // define parameters and their values
        cmd.Parameters.Add("@FirstName", SqlDbType.VarChar, 50).Value = firstName;
        cmd.Parameters.Add("@Lastname", SqlDbType.VarChar, 50).Value = lastName;
        cmd.Parameters.Add("@Username", SqlDbType.VarChar, 50).Value = userName;
        cmd.Parameters.Add("@Password", SqlDbType.VarChar, 50).Value = password;
        cmd.Parameters.Add("@Age", SqlDbType.Int).Value = age;
        cmd.Parameters.Add("@Gender", SqlDbType.VarChar, 50).Value = gender;
        cmd.Parameters.Add("@Contact", SqlDbType.VarChar, 50).Value = contact;

        // open connection, execute INSERT, close connection
        cn.Open();
        cmd.ExecuteNonQuery();
        cn.Close();
    }
}

Code like this:

• is not vulnerable to SQL injection attacks
• performs much better on SQL Server (since the query is parsed once into an execution plan, then cached and reused later on)
• separates the event handler (code-behind file) from your actual database code (putting things where they belong - helping to avoid "overweight" code-behinds with tons of spaghetti code, doing everything from handling UI events to database access - NOT a good design!)

Math.min uses a simple comparison to do its thing. The only advantage to not using Math.min is to save the extra function calls, but that is a negligible saving.

If you have more than just three numbers, having a minimum method for any number of doubles might be valuable and would look something like:

public static double min(double ... numbers) {
    double min = numbers[0];
    for (int i=1 ; i<numbers.length ; i++) {
        min = (min <= numbers[i]) ? min : numbers[i];
    }
    return min;
}

For three numbers this is the functional equivalent of Math.min(a, Math.min(b, c)); but you save one method invocation.

Warning - this could potentially overwrite files.

git init     
git remote add origin PATH/TO/REPO     
git fetch     
git checkout -t origin/master -f

Modified from @cmcginty's answer - without the -f it didn't work for me

Enclose your text in
--Here-- with the space you want in new line. save it in a String variable then pass it in Html.fromHtml().

One can also use the command line utilities included in poppler-utils package:

sudo apt-get install poppler-utils
pdftoppm --help
pdftocairo --help

Example:

pdftocairo -png mypage.pdf mypage.png

git revert doesn't take a filename parameter. Do you want git checkout?

Simplest of all solutions:

filtered_df = df[df['name'].notnull()]

Thus, it filters out only rows that doesn't have NaN values in 'name' column.

For multiple columns:

filtered_df = df[df[['name', 'country', 'region']].notnull().all(1)]

You have to roll your own. E.g.,

You can't reference an alias except in ORDER BY because SELECT is the second last clause that's evaluated. Two workarounds:

SELECT BalanceDue FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices
) AS x
WHERE BalanceDue > 0;

Or just repeat the expression:

SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
WHERE  (InvoiceTotal - PaymentTotal - CreditTotal)  > 0;

I prefer the latter. If the expression is extremely complex (or costly to calculate) you should probably consider a computed column (and perhaps persisted) instead, especially if a lot of queries refer to this same expression.

PS your fears seem unfounded. In this simple example at least, SQL Server is smart enough to only perform the calculation once, even though you've referenced it twice. Go ahead and compare the plans; you'll see they're identical. If you have a more complex case where you see the expression evaluated multiple times, please post the more complex query and the plans.

Here are 5 example queries that all yield the exact same execution plan:

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE LEN(name) + column_id > 30;

SELECT x FROM (
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE column_id + LEN(name) > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE LEN(name) + column_id > 30;

Resulting plan for all five queries:

In PHP there is a pretty good function utf8_encode() to solve this issue.

echo utf8_encode("Résumé");

//will output Résumé instead of R?sum?

Use the method .rdd like this:

rdd = df.rdd

David's answer is correct, but if it's still a little abstract, here are two examples:

1. You might want to zero all freed pointers to catch memory problems earlier. C-style you'd do:

   void freeAndZero(void** ptr)
   {
       free(*ptr);
       *ptr = 0;
   }
   
   void* ptr = malloc(...);
   
   ...
   
   freeAndZero(&ptr);
   

   In C++ to do the same, you might do:

   template<class T> void freeAndZero(T* &ptr)
   {
       delete ptr;
       ptr = 0;
   }
   
   int* ptr = new int;
   
   ...
   
   freeAndZero(ptr);
   

2. When dealing with linked-lists - often simply represented as pointers to a next node:

   struct Node
   {
       value_t value;
       Node* next;
   };
   

   In this case, when you insert to the empty list you necessarily must change the incoming pointer because the result is not the NULL pointer anymore. This is a case where you modify an external pointer from a function, so it would have a reference to pointer in its signature:

   void insert(Node* &list)
   {
       ...
       if(!list) list = new Node(...);
       ...
   }
   

There's an example in this question.

C2DM: your app-users must have the gmail account.

MQTT: when your connection reached to 1024, it will stop work because of it used "select model " of linux.

There is a free push service and api for android, you can try it: http://push-notification.org

The dig utility is pretty convenient to use. The order of the arguments don't really matter.I'll show you some easy examples.
To get all root name servers use

# dig

To get a TXT record of a specific host use

# dig example.com txt
# dig host.example.com txt

To query a specific name server just add @nameserver.tld

# dig host.example.com txt @a.iana-servers.net

The SPF RFC4408 says that SPF records can be stored as SPF or TXT. However nearly all use only TXT records at the moment. So you are pretty safe if you only fetch TXT records.

I made a SPF checker for visualising the SPF records of a domain. It might help you to understand SPF records better. You can find it here: http://spf.myisp.ch

May be useful for java and jstl.

1. Initialize variable with localized message.
2. After that it is possible to use it in jstl toLowerCase function.
3. Transform with CSS.

In JSP

1.

<fmt:message key="some.key" var="item"/>

2.

<div class="content">
  <a href="#">${fn:toLowerCase(item)}</a>
</div>

In CSS

3.

.content {
  text-transform:capitalize;

you can save the path of the image in the database or save the image itself as a BLOB ( binary - array of bytes)..it depends on the case you got,if your application is a web application,then saving the path of the image is much better.but if you got a client based application that connects to a centralized database,then you must save it as binary.

I had this same issue then i corrected the Engine name as Innodb in both parent and child tables and corrected the reference field name FOREIGN KEY (c_id) REFERENCES x9o_parent_table(c_id)
then it works fine and the tables are installed correctly. This will be use full for someone.

0 */1 * * * “At minute 0 past every hour.”

0 */2 * * * “At minute 0 past every 2nd hour.”

This is the proper way to set cronjobs for every hr.

It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:

• ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

• EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

  • If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL values, this foreign will be set to null and if you call SaveChanges this NULL value for the childEntity will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE statement. No DELETE statement occurs.

  • If the relationship is required (the FK doesn't allow NULL values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges - the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.

  • If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL) EF will mark the childEntity as Deleted as well. If you call SaveChanges a SQL DELETE statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)

You shouldn't have to set height: 100% at any point if you want your container to fill the page. Chances are, your problem is rooted in the fact that you haven't cleared the floats in the container's children. There are quite a few ways to solve this problem, mainly adding overflow: hidden to the container.

#container { overflow: hidden; }

Should be enough to solve whatever height problem you're having.

The only way I able to get this to work was by doing this on the presenting view controller:

    func didTapButton() {
    self.definesPresentationContext = true
    self.modalTransitionStyle = .crossDissolve
    let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "YourViewController") as! YourViewController
    let navController = UINavigationController(rootViewController: yourVC)
    navController.modalPresentationStyle = .overCurrentContext
    navController.modalTransitionStyle = .crossDissolve
    self.present(navController, animated: true, completion: nil)
}

As of Mac OS X Lion 10.7, Terminal includes exactly this functionality as a Service. As with most Services, these are disabled by default, so you'll need to enable this to make it appear in the Services menu.

System Preferences > Keyboard > Shortcuts > Services

Enable New Terminal at Folder. There's also New Terminal Tab at Folder, which will create a tab in the frontmost Terminal window (if any, else it will create a new window). These Services work in all applications, not just Finder, and they operate on folders as well as absolute pathnames selected in text.

You can even assign command keys to them.

Services appear in the Services submenu of each application menu, and within the contextual menu (Control-Click or Right-Click on a folder or pathname).

The New Terminal at Folder service will become active when you select a folder in Finder. You cannot simply have the folder open and run the service "in place". Go back to the parent folder, select the relevant folder, then activate the service via the Services menu or context menu.

In addition, Lion Terminal will open a new terminal window if you drag a folder (or pathname) onto the Terminal application icon, and you can also drag to the tab bar of an existing window to create a new tab.

Finally, if you drag a folder or pathname onto a tab (in the tab bar) and the foreground process is the shell, it will automatically execute a "cd" command. (Dragging into the terminal view within the tab merely inserts the pathname on its own, as in older versions of Terminal.)

You can also do this from the command line or a shell script:

open -a Terminal /path/to/folder

This is the command-line equivalent of dragging a folder/pathname onto the Terminal application icon.

On a related note, Lion Terminal also has new Services for looking up man pages: Open man page in Terminal displays the selected man page topic in a new terminal window, and Search man Pages in Terminal performs "apropos" on the selected text. The former also understands man page references ("open(2)"), man page command line arguments ("2 open") and man page URLs ("x-man-page://2/open").

For me I wanted a regex which supports a strings as preceding. Basically, the motive is to support some foreign countries postal format as it should be an alphanumeric with spaces allowed.

1. ABC123
2. ABC 123
3. ABC123(space)
4. ABC 123 (space)

So I ended up by writing custom regex as below.

/^([a-z]+[\s]*[0-9]+[\s]*)+$/i

Here, I gave * in [\s]* as it is not mandatory to have a space. A postal code may or may not contains space in my case.

just as a .crt file is in .pem format, a .key file is also stored in .pem format. Assuming that the cert is the only thing in the .crt file (there may be root certs in there), you can just change the name to .pem. The same goes for a .key file. Which means of course that you can rename the .pem file to .key.

Which makes gtrig's answer the correct one. I just thought I'd explain why.

Many suggestions here, most along the lines of git checkout $revision -- $file. A couple of obscure alternatives:

git show $revision:$file > $file

And also, I use this a lot just to see a particular version temporarily:

git show $revision:$file

or

git show $revision:$file | vim -R -

(OBS: $file needs to be prefixed with ./ if it is a relative path for git show $revision:$file to work)

And the even more weird:

git archive $revision $file | tar -x0 > $file

Either != or ne will work, but you need to get the accessor syntax and nested quotes sorted out.

<c:if test="${content.contentType.name ne 'MCE'}">
    <%-- snip --%>
</c:if>

Isn't the point of arrays to be efficient? If you're just iterating through values, I think a cursor on a temporary (or permanent) table makes more sense than seeking commas, no? Also cleaner. Lookup "mysql DECLARE CURSOR".

For random access a temporary table with numerically indexed primary key. Unfortunately the fastest access you'll get is a hash table, not true random access.

Use java -cp myjar.jar com.mypackage.myClass.

1. If the class is not in a package then simply java -cp myjar.jar myClass.

2. If you are not within the directory where myJar.jar is located, then you can do:

   1. On Unix or Linux platforms:

      java -cp /location_of_jar/myjar.jar com.mypackage.myClass

   2. On Windows:

      java -cp c:\location_of_jar\myjar.jar com.mypackage.myClass

The variable mean_data is a nested list, in Python accessing a nested list cannot be done by multi-dimensional slicing, i.e.: mean_data[1,2], instead one would write mean_data[1][2].

This is becausemean_data[2] is a list. Further indexing is done recursively - since mean_data[2] is a list, mean_data[2][0] is the first index of that list.

Additionally, mean_data[:][0] does not work because mean_data[:] returns mean_data.

The solution is to replace the array ,or import the original data, as follows:

mean_data = np.array(mean_data)

numpy arrays (like MATLAB arrays and unlike nested lists) support multi-dimensional slicing with tuples.

The standard way to see if a file exists is with the Test-Path cmdlet.

Test-Path -path $filename

If you're using Python 3 then you must install as follows:

sudo apt-get update
sudo apt-get install python3-tk

Tkinter for Python 2 (python-tk) is different from Python 3's (python3-tk).

Replace the whitespace characters, and then convert it(using the intval function or by regular typecasting)

intval(str_replace(" ", "", $b))

I would have rather commented but I don't have a high enough rep.

As far as I am aware, for positive arguments and a divisor which is a power of 2, this is the fastest way (tested in CUDA):

//example y=8
q = (x >> 3) + !!(x & 7);

For generic positive arguments only, I tend to do it like so:

q = x/y + !!(x % y);

(Not cross-browser tested), but this is my answer:

  height: 40px;
  line-height: 40px; /* adjust line height to align vertically*/
  padding:0;
  border-radius: 50%;
}

• vertical center via the line-height property
• padding becomes useless and must be reset
• border-radius independant of the button size

Loads n scripts one by one (useful if for example 2nd file needs the 1st one):

(function self(a,cb,i){
    i = i || 0; 
    cb = cb || function(){};    
    if(i==a.length)return cb();
    $.getScript(a[i++],self.bind(0,a,cb,i));                    
})(['list','of','script','urls'],function(){console.log('done')});

"pull-left" is what you need, it looks like you are using Bootstrap 2, I am not sure if that is available, consider bootstrap 3, unless ofcourse it is a huge rework! ... for Bootstrap 3 but you need to make sure you have 12 columns in each row as well, otherwise you will have issues.

No, you're creating an array, but there's a big difference:

char *string = "Some CONSTANT string";
printf("%c\n", string[1]);//prints o
string[1] = 'v';//INVALID!!

The array is created in a read only part of memory, so you can't edit the value through the pointer, whereas:

char string[] = "Some string";

creates the same, read only, constant string, and copies it to the stack array. That's why:

string[1] = 'v';

Is valid in the latter case.
If you write:

char string[] = {"some", " string"};

the compiler should complain, because you're constructing an array of char arrays (or char pointers), and assigning it to an array of chars. Those types don't match up. Either write:

char string[] = {'s','o','m', 'e', ' ', 's', 't','r','i','n','g', '\o'};
//this is a bit silly, because it's the same as char string[] = "some string";
//or
char *string[] = {"some", " string"};//array of pointers to CONSTANT strings
//or
char string[][10] = {"some", " string"};

Where the last version gives you an array of strings (arrays of chars) that you actually can edit...

//Class Name
public class ClassName {
//Make it runnable
public static void main(String args[]) throws MalformedURLException{
//Get the URL
URL img = this.getClass().getResource("src/Name.gif");
//Make it to a Icon
Icon icon = new ImageIcon(img);
//Make a new JLabel that shows "icon"
JLabel Gif = new JLabel(icon);

//Make a new Window
JFrame main = new JFrame("gif");
//adds the JLabel to the Window
main.getContentPane().add(Gif);
//Shows where and how big the Window is
main.setBounds(x, y, H, W);
//set the Default Close Operation to Exit everything on Close
main.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Open the Window
main.setVisible(true);
   }
}

There is no button type cancel https://www.w3schools.com/jsref/prop_pushbutton_type.asp

The magical Xcode Organizer isn't that magical about symbolicating my app. I got no symbols at all for the crash reports that I got back from Apple from a failed app submission.

I tried using the command-line, putting the crash report in the same folder as the .app file (that I submitted to the store) and the .dSYM file:

$ symbolicatecrash "My App_date_blahblah-iPhone.crash" "My App.app"

This only provided symbols for my app and not the core foundation code, but it was better than the number dump that Organizer is giving me and was enough for me to find and fix the crash that my app had. If anyone knows how to extend this to get Foundation symbols it would be appreciated.

In my case, it was that the app had defaulted to a Wearable target device.

I removed the reference to Wearable in my Manifest, and the problem was solved.

<uses-library android:name="com.google.android.wearable" android:required="true" />

import sys
for x in range(10000):
    print "HAPPY >> %s <<\r" % str(x),
    sys.stdout.flush()

I combined two solutions and it works fine for me.

window.addEventListener("orientationchange", function() {                   
    if (window.matchMedia("(orientation: portrait)").matches) {
       alert("PORTRAIT")
     }
    if (window.matchMedia("(orientation: landscape)").matches) {
      alert("LANSCAPE")
     }
}, false);

go Setting -> General and change url in WordPress Address (URL) and Site Address (URL)

enter your pc name or your ip address in place of localhost

before : http://localhost/wordpress-test

after : http://your-pc-name/wordpress-test

...and that's it..you can access wordpress from any pc in your LAN...!!!

If you have a compiler that supports C99 compound literals:

#define IS_BIG_ENDIAN (!*(unsigned char *)&(uint16_t){1})

or:

#define IS_BIG_ENDIAN (!(union { uint16_t u16; unsigned char c; }){ .u16 = 1 }.c)

In general though, you should try to write code that does not depend on the endianness of the host platform.

Example of host-endianness-independent implementation of ntohl():

uint32_t ntohl(uint32_t n)
{
    unsigned char *np = (unsigned char *)&n;

    return ((uint32_t)np[0] << 24) |
        ((uint32_t)np[1] << 16) |
        ((uint32_t)np[2] << 8) |
        (uint32_t)np[3];
}

The original post requested for code which prints some rows (if they are true for some condition) plus the following row. My implementation would be this:

text = """1 sfasdf
asdfasdf
2 sfasdf
asdfgadfg
1 asfasdf
sdfasdgf
"""

text = text.splitlines()
rows_to_print = {}

for line in range(len(text)):
    if text[line][0] == '1':
        rows_to_print = rows_to_print | {line, line + 1}

rows_to_print = sorted(list(rows_to_print))

for i in rows_to_print:
    print(text[i])

I faced mostly the same issue. Im my case uuid is stored as BINARY(16) and has NOT NULL UNIQUE constraints. And i faced with the issue when the same UUID was generated for every row, and UNIQUE constraint does not allow this. So this query does not work:

UNHEX(REPLACE(uuid(), '-', ''))

But for me it worked, when i used such a query with nested inner select:

UNHEX(REPLACE((SELECT uuid()), '-', ''))

Then is produced unique result for every entry.

You could use strcmp():

/* strcmp example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char szKey[] = "apple";
  char szInput[80];
  do {
     printf ("Guess my favourite fruit? ");
     gets (szInput);
  } while (strcmp (szKey,szInput) != 0);
  puts ("Correct answer!");
  return 0;
}

You want to do

git fetch --prune origin
git reset --hard origin/master
git clean -f -d

This makes your local repo exactly like your remote repo.

Remember to replace origin and master with the remote and branch that you want to synchronize with.

On Ubuntu 16.04 php7 is now the default, so if you follow the top answers and are still having this issue, check your php version.

php --version

If your default php version is php7, but you followed an answer using php5 packages, you can use the following command to set the default version of php to php5.6:

sudo update-alternatives --set php $(which php5.6)

I solved this problem on my Galaxy S4 phone by replacing context.startActivity(addAccountIntent); with startActivity(new Intent(Settings.ACTION_ADD_ACCOUNT));

Use Mach-OView for viewing all the Symbols in dylib

https://sourceforge.net/projects/machoview/

The easy way and fast way to do this is:

three = [sum(i) for i in zip(first,second)] # [7,9,11,13,15]

Alternatively, you can use numpy sum:

from numpy import sum
three = sum([first,second], axis=0) # array([7,9,11,13,15])

import threading 

# global variable x 
x = 0

def increment(): 
    """ 
    function to increment global variable x 
    """
    global x 
    x += 1

def thread_task(): 
    """ 
    task for thread 
    calls increment function 100000 times. 
    """
    for _ in range(100000): 
        increment() 

def main_task(): 
    global x 
    # setting global variable x as 0 
    x = 0

    # creating threads 
    t1 = threading.Thread(target=thread_task) 
    t2 = threading.Thread(target=thread_task) 

    # start threads 
    t1.start() 
    t2.start() 

    # wait until threads finish their job 
    t1.join() 
    t2.join() 

if __name__ == "__main__": 
    for i in range(10): 
        main_task() 
        print("Iteration {0}: x = {1}".format(i,x))

It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:

When location matches the last part of the directive’s value: it is better to use the root directive instead:

which would yield:

server {
  listen        8080;
  server_name   www.mysite.com mysite.com;
  error_log     /home/www-data/logs/nginx_www.error.log;
  error_page    404    /404.html;

  location /public/doc/ {
    autoindex on;
    root  /home/www-data/mysite;
  } 

  location = /404.html {
    root /home/www-data/mysite/static/html;
  }       
}

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

Yesterday Date can be calculated as:-

let now = new Date();
    var defaultDate = now - 1000 * 60 * 60 * 24 * 1;
    defaultDate = new Date(defaultDate);

getArguments() is returning null because "Its doesn't get anything"

Try this code to handle this situation

if(getArguments()!=null)
{
int myInt = getArguments().getInt(key, defaultValue);
}

Here is an example of using the loop:

echo off
cls

:begin

set /P M=Input text to encode md5, press ENTER to exit: 
if %M%==%M1% goto end

echo.|set /p ="%M%" | openssl md5

set M1=%M%
Goto begin

This is the simple batch i use when i need to encrypt any message into md5 hash on Windows(openssl required), and the program would loyally repeat itself except given Ctrl+C or empty input.

Try This url with valid userid and access token:

https://graph.facebook.com/{userid}/photos?limit=20&access_token={access_token}

Every form of the query string retrievable from flask request object as described in O'Reilly Flask Web Devleopment:

From O'Reilly Flask Web Development, and as stated by Manan Gouhari earlier, first you need to import request:

from flask import request

request is an object exposed by Flask as a context variable named (you guessed it) request. As its name suggests, it contains all the information that the client included in the HTTP request. This object has many attributes and methods that you can retrieve and call, respectively.

You have quite a few request attributes which contain the query string from which to choose. Here I will list every attribute that contains in any way the query string, as well as a description from the O'Reilly book of that attribute.

First there is args which is "a dictionary with all the arguments passed in the query string of the URL." So if you want the query string parsed into a dictionary, you'd do something like this:

from flask import request

@app.route('/'):
    queryStringDict = request.args

(As others have pointed out, you can also use .get('<arg_name>') to get a specific value from the dictionary)

Then, there is the form attribute, which does not contain the query string, but which is included in part of another attribute that does include the query string which I will list momentarily. First, though, form is "A dictionary with all the form fields submitted with the request." I say that to say this: there is another dictionary attribute available in the flask request object called values. values is "A dictionary that combines the values in form and args." Retrieving that would look something like this:

from flask import request

@app.route('/'):
    formFieldsAndQueryStringDict = request.values

(Again, use .get('<arg_name>') to get a specific item out of the dictionary)

Another option is query_string which is "The query string portion of the URL, as a raw binary value." Example of that:

from flask import request

@app.route('/'):
    queryStringRaw = request.query_string

Then as an added bonus there is full_path which is "The path and query string portions of the URL." Por ejemplo:

from flask import request

@app.route('/'):
    pathWithQueryString = request.full_path

And finally, url, "The complete URL requested by the client" (which includes the query string):

from flask import request

@app.route('/'):
    pathWithQueryString = request.url

Happy hacking :)

In my case I was using ClassName.

getComputedStyle( document.getElementsByClassName(this_id)) //error

It will also work without 2nd argument " ".

Here is my complete running code :

function changeFontSize(target) {

  var minmax = document.getElementById("minmax");

  var computedStyle = window.getComputedStyle
        ? getComputedStyle(minmax) // Standards
        : minmax.currentStyle;     // Old IE

  var fontSize;

  if (computedStyle) { // This will be true on nearly all browsers
      fontSize = parseFloat(computedStyle && computedStyle.fontSize);

      if (target == "sizePlus") {
        if(fontSize<20){
        fontSize += 5;
        }

      } else if (target == "sizeMinus") {
        if(fontSize>15){
        fontSize -= 5;
        }
      }
      minmax.style.fontSize = fontSize + "px";
  }
}


onclick= "changeFontSize(this.id)"

Asp:Hyperlink http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.hyperlink.aspx

For a simple two- (or one) liner this code can be:

checkboxes = document.getElementsByName("NameOfCheckboxes");
selectedCboxes = Array.prototype.slice.call(checkboxes).filter(ch => ch.checked==true);

Here the Array.prototype.slice.call() part converts the object NodeList of all the checkboxes holding that name ("NameOfCheckboxes") into a new array, on which you then use the filter method. You can then also, for example, extract the values of the checkboxes by adding a .map(ch => ch.value) on the end of line 2. The => is javascript's arrow function notation.

I am looking for a way to create a select without repeating the conditional query.

I'm assuming that you don't want to repeat Foo-stuff+bar. You could put your calculation into a derived table:

SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END 
FROM (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable) AS a

A common table expression would work just as well:

WITH a AS (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable)
SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END    
FROM a

Also, each part of your switch should return the same datatype, so you may have to cast one or more cases.

xsv is more than a viewer. I recommend it for most CSV task on the command line, especially when dealing with large datasets.

You can do it also in more 'object way' and still easy-to-read:

$('#content ul').append(
    $('<li>').append(
        $('<a>').attr('href','/user/messages').append(
            $('<span>').attr('class', 'tab').append("Message center")
)));    

You don't have to fight with quotes then, but must keep trace of braces :)

If you response is like {'customer':{'first_name':'John','last_name':'Cena'}}

var d = JSON.parse(response);
alert(d.customer.first_name); // contains "John"

Thanks,

If you're able to extract the loop code into a function, a return statement can be used to exit the outermost loop at any time.

def foo():
    for x in range(10):
        for y in range(10):
            print(x*y)
            if x*y > 50:
                return
foo()

If it's hard to extract that function you could use an inner function, as @bjd2385 suggests, e.g.

def your_outer_func():
    ...
    def inner_func():
        for x in range(10):
            for y in range(10):
                print(x*y)
                if x*y > 50:
                    return
    inner_func()
    ...

jQuery makes it easy to set any attributes for an element - just use the .attr() method:

$(document).ready(function() {
    $("input").attr({
       "max" : 10,        // substitute your own
       "min" : 2          // values (or variables) here
    });
});

The document ready handler is not required if your script block appears after the element(s) you want to manipulate.

Using a selector of "input" will set the attributes for all inputs though, so really you should have some way to identify the input in question. If you gave it an id you could say:

$("#idHere").attr(...

...or with a class:

$(".classHere").attr(...

Launch image and Slash image size for Google Play Store app submission

1. High-res icon. PFB the table for required sizes 32-bit PNG (with alpha), Dimensions: 512px by 512px, Maximum file size: 1024KB

Required Launch Icon And Splash Image size

2. At least 2 screenshots are required overall (Max 8 screenshots per type, Types include "Phone", "7-inch tablet" and "10-inch tablet”). JPEG or 24-bit PNG (no alpha), Minimum dimension: 320px, Maximum dimension: 3840px, Sample sizes: 320 x 480, 480 x 800, 480 x 854,1280 x 720, 1280 x 800 24 bit PNG or JPEG

Step 1: Create a class AppStatus in your project(you can give any other name also). Then please paste the given below lines into your code:

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.util.Log;


public class AppStatus {

    private static AppStatus instance = new AppStatus();
    static Context context;
    ConnectivityManager connectivityManager;
    NetworkInfo wifiInfo, mobileInfo;
    boolean connected = false;

    public static AppStatus getInstance(Context ctx) {
        context = ctx.getApplicationContext();
        return instance;
    }

    public boolean isOnline() {
        try {
            connectivityManager = (ConnectivityManager) context
                        .getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        connected = networkInfo != null && networkInfo.isAvailable() &&
                networkInfo.isConnected();
        return connected;


        } catch (Exception e) {
            System.out.println("CheckConnectivity Exception: " + e.getMessage());
            Log.v("connectivity", e.toString());
        }
        return connected;
    }
}

Step 2: Now to check if the your device has network connectivity then just add this code snippet where ever you want to check ...

if (AppStatus.getInstance(this).isOnline()) {

    Toast.makeText(this,"You are online!!!!",8000).show();

} else {

    Toast.makeText(this,"You are not online!!!!",8000).show();
    Log.v("Home", "############################You are not online!!!!");    
}

This works perfect for me

{
    test: /\.(js|jsx)$/,
    loader: 'babel-loader',

    }
},

You can't style a disabled checkbox directly because it's controlled by the browser / OS.

However you can be clever and replace the checkbox with a label that simulates a checkbox using pure CSS. You need to have an adjacent label that you can use to style a new "pseudo checkbox". Essentially you're completely redrawing the thing but it gives you complete control over how it looks in any state.

I've thrown up a basic example so that you can see it in action: http://jsfiddle.net/JohnSReid/pr9Lx5th/3/

To prevent the flex items from shrinking, set the flex shrink factor to 0:

The flex shrink factor determines how much the flex item will shrink relative to the rest of the flex items in the flex container when negative free space is distributed. When omitted, it is set to 1.

pack_forget and grid_forget will only remove widgets from view, it doesn't destroy them. If you don't plan on re-using the widgets, your only real choice is to destroy them with the destroy method.

To do that you have two choices: destroy each one individually, or destroy the frame which will cause all of its children to be destroyed. The latter is generally the easiest and most effective.

Since you claim you don't want to destroy the container frame, create a secondary frame. Have this secondary frame be the container for all the widgets you want to delete, and then put this one frame inside the parent you do not want to destroy. Then, it's just a matter of destroying this one frame and all of the interior widgets will be destroyed along with it.

The equivalence would be

for i in (0...array.size)
end

or

(0...array.size).each do |i|
end

or

i = 0
while i < array.size do
   array[i]
   i = i + 1 # where you may freely set i to any value
end

Instead of inserting the below many times into each page...

<div class="device-xs visible-xs"></div>
<div class="device-sm visible-sm"></div>
<div class="device-md visible-md"></div>
<div class="device-lg visible-lg"></div>

Just use JavaScript to dynamically insert it into every page (note that I have updated it to work with Bootstrap 3 with .visible-*-block:

// Make it easy to detect screen sizes
var bootstrapSizes = ["xs", "sm", "md", "lg"];
for (var i = 0; i < bootstrapSizes.length; i++) {
    $("<div />", {
        class: 'device-' + bootstrapSizes[i] + ' visible-' + bootstrapSizes[i] + '-block'
    }).appendTo("body");
}

I had the same problem with SQL Server 2008 R2 and when I checked "SQL Server Configuration Manager" My SQL Server instance had Stopped. Right Clicking and Starting the Instance solved the issue.

Have you tried using the value in MB ?

php_value memory_limit 2048M

Also try editing this value in php.ini not Apache.

Use the second parameter of json_decode to make it return an array:

$result = json_decode($data, true);

The commit should be present in your local, check by using git log.

If the commit is not present then try git fetch to update the local with the latest remote.

if The wampserver Version 2.5 then change apache configuration as

httpd.conf (apache configuration file): From

#LoadModule rewrite_module modules/mod_rewrite.so** 

To ,delete the #

LoadModule rewrite_module modules/mod_rewrite.so** 

this working fine to me

Deleting the file will also remove the content. See remove file.

Everything in the java.lang package is implicitly imported (including String) and you do not need to do so yourself. This is simply a feature of the Java language. ArrayList and HashMap are however in the java.util package, which is not implicitly imported.

The package java.lang mostly includes essential features, such a class version of primitives, basic exceptions and the Object class. This being integral to most programs, forcing people to import them is redundant and thus the contents of this package are implicitly imported.

Please note that newer versions of MPL have a shortcut for this task. An example is shown in the other answer to this question: https://stackoverflow.com/a/11386056/42346

The code below is for illustrative purposes and may not necessarily be optimized.

    y1 = np.cos(x)
    y2 = (x**2)
    y3 = (x**3)
    yn = (y1,y2,y3)
    COLORS = ('b','g','k')

    for i,y in enumerate(yn):
        ax = fig.add_subplot(len(yn),1,i+1)

        ax.plot(x, y, ls='solid', color=COLORS[i]) 

        if i != len(yn) - 1:
            # all but last 
            ax.set_xticklabels( () )

Change it to http://lvh.me:24448/HomePage.aspx

The Qt documentations has an Image Viewer example which demonstrates handling resizing images inside a QLabel. The basic idea is to use QScrollArea as a container for the QLabel and if needed use label.setScaledContents(bool) and scrollarea.setWidgetResizable(bool) to fill available space and/or ensure QLabel inside is resizable. Additionally, to resize QLabel while honoring aspect ratio use:

label.setPixmap(pixmap.scaled(width, height, Qt::KeepAspectRatio, Qt::FastTransformation));

The width and height can be set based on scrollarea.width() and scrollarea.height(). In this way there is no need to subclass QLabel.

As pointed out by others, Python 3's int does not have a maximum size, but if you just need something that's guaranteed to be higher than any other int value, then you can use the float value for Infinity, which you can get with float("inf").

For single value the datetime.strptime method is the fastest

import arrow
from datetime import datetime
import pandas as pd

l = ['24052010']

%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.86 µs ± 56.5 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
305 µs ± 6.32 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
46 µs ± 978 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

For a list of values the pandas pd.to_datetime is the fastest

l = ['24052010'] * 1000

%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.32 ms ± 89.6 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
1.76 ms ± 27.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
44.5 ms ± 522 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

For ISO8601 datetime format the ciso8601 is a rocket

import ciso8601

l = ['2010-05-24'] * 1000

%timeit _ = list(map(lambda x: ciso8601.parse_datetime(x).date(), l))
241 µs ± 3.24 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Seeing the answers I have nothing else to add but one more thing:

in your test.html file you have written

link rel="stylesheet" type="css/text" href="test.css"/

see where you have written

type="css/text"

there you need to change into

type="text/css"

so it will look like that

link rel="stylesheet" type="text/css" href="test.css"/

and in this case the CSS file will be linked to HTML file

data.userID = "10";

The short answer is you DON'T do this in CSS. Internet Explorer has support for something called CSS Expressions, but this isn't standard and is definitely not supported by other browsers like FireFox for instance.

You'd be better off doing this in JavaScript.

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

for Bootstrap 4, this should work for you

 $('.modal').remove();
 $('.modal-backdrop').remove();

I used the following code, it's working!

using System.Data.OleDb;
using System.IO;
using System.Text.RegularExpressions;

private void btopen_Click(object sender, EventArgs e)
{
   try
   {
     OpenFileDialog openFileDialog1 = new OpenFileDialog();  //create openfileDialog Object
     openFileDialog1.Filter = "XML Files (*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb) |*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb";//open file format define Excel Files(.xls)|*.xls| Excel Files(.xlsx)|*.xlsx| 
     openFileDialog1.FilterIndex = 3;

     openFileDialog1.Multiselect = false;        //not allow multiline selection at the file selection level
     openFileDialog1.Title = "Open Text File-R13";   //define the name of openfileDialog
     openFileDialog1.InitialDirectory = @"Desktop"; //define the initial directory

     if (openFileDialog1.ShowDialog() == DialogResult.OK)        //executing when file open
     {
       string pathName = openFileDialog1.FileName;
       fileName = System.IO.Path.GetFileNameWithoutExtension(openFileDialog1.FileName);
       DataTable tbContainer = new DataTable();
       string strConn = string.Empty;
       string sheetName = fileName;

       FileInfo file = new FileInfo(pathName);
       if (!file.Exists) { throw new Exception("Error, file doesn't exists!"); }
       string extension = file.Extension;
       switch (extension)
       {
          case ".xls":
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
          case ".xlsx":
                   strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pathName + ";Extended Properties='Excel 12.0;HDR=Yes;IMEX=1;'";
                   break;
          default:
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
         }
         OleDbConnection cnnxls = new OleDbConnection(strConn);
         OleDbDataAdapter oda = new OleDbDataAdapter(string.Format("select * from [{0}$]", sheetName), cnnxls);
         oda.Fill(tbContainer);

         dtGrid.DataSource = tbContainer;
       }

     }
     catch (Exception)
     {
        MessageBox.Show("Error!");
     }
  }

In here:

    if (ValidationUtils.isNullOrEmpty(lastName)) {
        registrationErrors.add(ValidationErrors.LAST_NAME);
    }
    if (!ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do

    if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.

Yes, there is a way. Its called custom fonts in CSS.Your CSS needs to be modified, and you need to upload those fonts to your website.

The CSS required for this is:

@font-face {
     font-family: Thonburi-Bold;
     src: url('pathway/Thonburi-Bold.otf'); 
}

This will get you the drives on the machine:

System.IO.DriveInfo.GetDrives()

These two methods will get you the bad characters to check:

System.IO.Path.GetInvalidFileNameChars();
System.IO.Path.GetInvalidPathChars();

The basic principle of centering a page is to have a body CSS and main_container CSS. It should look something like this:

body {
     margin: 0;
     padding: 0;
     text-align: center;
}
#main_container {
     margin: 0 auto;
     text-align: left;
}

sudo apt-get install python3-dev
sudo apt-get install libmysqlclient-dev
sudo apt-get install zlib1g-dev
sudo pip3 install mysqlclient

that worked for me!

Even though you got this working, I recently had a similar encounter and no SO or Google searching was of any help as they all dealt with basic permission issues wheres the solution below is somewhat of an off setting that you wouldn't even think to check in most situations.

One thing to check for with permission denied that I recently found having issues with rsync myself where permissions were exactly the same on both servers including the owner and group but rsync transfers worked one way on one server but not the other way.

It turned out the server with problems that I was getting permission denied from had SELinux enabled which in turn overrides POSIX permissions on files/folders. So even though the folder in question could have been 777 with root running, the command SELinux was enabled and would in turn overwrite those permissions which produced a "permission denied"-error from rsync.

You can run the command getenforce to see if SELinux is enabled on the machine.

In my situation I ended up just disabling SELINUX completely because it wasn't needed and already disabled on the server that was working fine and just caused problems being enabled. To disable, open /etc/selinux/config and set SELINUX=disabled. To temporarily disable you can run the command setenforce 0 which will set SELinux into a permissive state rather then enforcing state which causes it to print warnings instead of enforcing.

It's nice to have something to distinguish private vs. public variables, but I don't like '_' in general coding. If I can help it in new code, I avoid their use.

You might want to check https://github.com/Thor1Khan/mongo.git it uses a minimal workaround the 32 bit atomic operations on 64 bits operands (could use assembly but it doesn't seem to be mandatory here) Only digital bugs were harmed before committing

You don't have to use jQuery. Plain JavaScript will do. I wouldn't recommend any library that ports XML standards onto JavaScript, and I was frustrated that no other solution existed for this so I wrote my own library.

I adapted regex to work with JSON.

First, stringify the JSON object. Then, you need to store the starts and lengths of the matched substrings. For example:

"matched".search("ch") // yields 3

For a JSON string, this works exactly the same (unless you are searching explicitly for commas and curly brackets in which case I'd recommend some prior transform of your JSON object before performing regex (i.e. think :, {, }).

Next, you need to reconstruct the JSON object. The algorithm I authored does this by detecting JSON syntax by recursively going backwards from the match index. For instance, the pseudo code might look as follows:

find the next key preceding the match index, call this theKey
then find the number of all occurrences of this key preceding theKey, call this theNumber
using the number of occurrences of all keys with same name as theKey up to position of theKey, traverse the object until keys named theKey has been discovered theNumber times
return this object called parentChain

With this information, it is possible to use regex to filter a JSON object to return the key, the value, and the parent object chain.

You can see the library and code I authored at http://json.spiritway.co/

You can also try to reset visual studio setting

1. Open Visual Studio Command Prompt

2. Enter command Devenv /ResetSettings

It will remove already saved TFS account and ask for credentials

used the following snippet and it worked fine..

.smallText .bmv-disclaimer {
   height: 40px;

Follow the below code.

Add this to your TS file.

declare this, top of your class.

declare var google;

declare the view child for Map and the input.

@ViewChild('mapElement', {static: true}) mapNativeElement: ElementRef;
@ViewChild('autoCompleteInput', {static: true}) inputNativeElement: any;

this method is run on ngOnInit() event or ngAfterViewInit() event.

autoComplete() {
    const map = new google.maps.Map(this.mapNativeElement.nativeElement, {
      center: {lat: -33.8688, lng: 151.2093},
      zoom: 7
    });

    const infowindow = new google.maps.InfoWindow();
    const infowindowContent = document.getElementById('infowindow-content');

    infowindow.setContent(infowindowContent);

    const marker = new google.maps.Marker({
      map: map,
      anchorPoint: new google.maps.Point(0, -29)
    });
    const autocomplete = new google.maps.places.Autocomplete(this.inputNativeElement.nativeElement as HTMLInputElement);
    autocomplete.addListener('place_changed', () => {
      infowindow.close();
      marker.setVisible(false);
      const place = autocomplete.getPlace();

      let cus_location = {
        lat: place.geometry.location.lat(),

      console.log('place data :................', cus_location); 
      localStorage.setItem('LOC_DATA', this.helper.encryptData(cus_location));

      if (!place.geometry) {
        // User entered the name of a Place that was not suggested and
        // pressed the Enter key, or the Place Details request failed.
        window.alert('No details available for input: ' + place.name );
        return;
      }

      if (place.geometry.viewport) {
        map.fitBounds(place.geometry.viewport);
      } else {
        map.setCenter(place.geometry.location);
        map.setZoom(17);  // Why 17? Because it looks good.
      }

      marker.setPosition(place.geometry.location);
      marker.setVisible(true);
      let address = '';
      if (place.address_components) {
        address = [

          (place.address_components[2] && place.address_components[2].short_name || '')
        ].join(' ');
      }

      if(infowindowContent){
        infowindowContent.children['place-icon'].src = place.icon;
        infowindowContent.children['place-name'].textContent = place.name;
        infowindowContent.children['place-address'].textContent = address;
      } 

      infowindow.open(map, marker);
    });

  }

calling the method on ngAfterViewInit.

ngAfterViewInit(): void {
    this.autoComplete();
  }

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

What if you specified the default value to return, instead of using default(T)?

public static T GetQueryString<T>(string key, T defaultValue) {...}

It makes calling it easier too:

var intValue = GetQueryString("intParm", Int32.MinValue);
var strValue = GetQueryString("strParm", "");
var dtmValue = GetQueryString("dtmPatm", DateTime.Now); // eg use today's date if not specified

The downside being you need magic values to denote invalid/missing querystring values.

A slight variation on andrew.fox answer, as the string to decode might not be a correct base64 encoded string:

using System;

namespace Service.Support
{
    public static class Base64
    {
        public static string ToBase64(this System.Text.Encoding encoding, string text)
        {

            {
                return null;
            }

            byte[] textAsBytes = encoding.GetBytes(text);
            return Convert.ToBase64String(textAsBytes);
        }

        public static bool TryParseBase64(this System.Text.Encoding encoding, string encodedText, out string decodedText)
        {
            if (encodedText == null)
            {
                decodedText = null;
                return false;
            }

            try
            {
                byte[] textAsBytes = Convert.FromBase64String(encodedText);
                decodedText = encoding.GetString(textAsBytes);
                return true;
            }
            catch (Exception)
            {

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {_x000D_
  var bd = $('<div class="modal-backdrop"></div>');_x000D_
  bd.appendTo(document.body);_x000D_
  setTimeout(function() {_x000D_
    bd.remove();_x000D_
  }, 2000);_x000D_
});

Here is my recursive approach:

function visit(object) {
    if (isIterable(object)) {
        forEachIn(object, function (accessor, child) {
            visit(child);
        });
    }
    else {
        var value = object;
        console.log(value);
    }
}

function forEachIn(iterable, functionRef) {
    for (var accessor in iterable) {
        functionRef(accessor, iterable[accessor]);
    }
}

function isIterable(element) {
    return isArray(element) || isObject(element);
}

function isArray(element) {
    return element.constructor == Array;
}

function isObject(element) {
    return element.constructor == Object;
}

The accepted answer detects digits but does not detect formated numbers, e.g. 2,000, nor decimals, e.g. 4.8. For such use -?\\d+(,\\d+)*?\\.?\\d+?:

Pattern p = Pattern.compile("-?\\d+(,\\d+)*?\\.?\\d+?");
List<String> numbers = new ArrayList<String>();
Matcher m = p.matcher("Government has distributed 4.8 million textbooks to 2,000 schools");
while (m.find()) {  
    numbers.add(m.group());
}   
System.out.println(numbers);

Output: [4.8, 2,000]

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

The regex will attempt to find a result, if there is none, it move to the next alternative. If no result is found, none of the 4 formats where present.

Stateless means there is no memory of the past. Every transaction is performed as if it were being done for the very first time.

Stateful means that there is memory of the past. Previous transactions are remembered and may affect the current transaction.

Stateless:

// The state is derived by what is passed into the function

function int addOne(int number)
{
    return number + 1;
}

Stateful:

// The state is maintained by the function

private int _number = 0; //initially zero

function int addOne()
{
   _number++;
   return _number;
}

A very useful solution to this issue which doesn't require from you to do the indexOf is using Apache Commons libraries.

 StringUtils.substringBetween(s, "(", ")");

This method will allow you even handle even if there multiple occurrences of the closing string which wont be easy by looking for indexOf closing string.

You can download this library from here: https://mvnrepository.com/artifact/org.apache.commons/commons-lang3/3.4

It's a simple problem. When you are running from terminal, you are running the php file from terminal as a privileged user. When you go to the php from your web browser, the php script is being run as the web server user which does not have permissions to execute files in your home directory. In Ubuntu, the www-data user is the apache web server user. If you're on ubuntu you would have to do the following: chown yourusername:www-data /home/testuser/testscript chmod g+x /home/testuser/testscript

what the above does is transfers user ownership of the file to you, and gives the webserver group ownership of it. the next command gives the group executable permission to the file. Now the next time you go ahead and do it from the browser, it should work.

I got the same error while following an old tutorial with (not old enough) AngularJS 1.4.3. By far the simplest solution is to edit angular.js source from

function $ControllerProvider() {
  var controllers = {},
      globals = false;

to

function $ControllerProvider() {
  var controllers = {},
      globals = true;

and just follow the tutorial as-is, and the deprecated global functions just work as controllers.

That is a "set subtraction" operation. Use the set data structure for that.

In Python 2.7:

x = {1,2,3,4,5,6,7,8,9,0}
y = {1,3,5,7,9}
print x - y

Output:

>>> print x - y
set([0, 8, 2, 4, 6])

I found it easier in following links:

In http://www.remondo.net/visitor-pattern-example-csharp/ I found an example that shows an mock example that shows what is benefit of visitor pattern. Here you have different container classes for Pill:

namespace DesignPatterns
{
    public class BlisterPack
    {
        // Pairs so x2
        public int TabletPairs { get; set; }
    }

    public class Bottle
    {
        // Unsigned
        public uint Items { get; set; }
    }

    public class Jar
    {
        // Signed
        public int Pieces { get; set; }
    }
}

As you see in above, You BilsterPack contain pairs of Pills' so you need to multiply number of pair's by 2. Also you may notice that Bottle use unit which is different datatype and need to be cast.

So in main method you may calculate pill count using following code:

foreach (var item in packageList)
{
    if (item.GetType() == typeof (BlisterPack))
    {
        pillCount += ((BlisterPack) item).TabletPairs * 2;
    }
    else if (item.GetType() == typeof (Bottle))
    {
        pillCount += (int) ((Bottle) item).Items;
    }
    else if (item.GetType() == typeof (Jar))
    {
        pillCount += ((Jar) item).Pieces;
    }
}

Notice that above code violate Single Responsibility Principle. That means you must change main method code if you add new type of container. Also making switch longer is bad practice.

So by introducing following code:

public class PillCountVisitor : IVisitor
{
    public int Count { get; private set; }

    #region IVisitor Members

    public void Visit(BlisterPack blisterPack)
    {
        Count += blisterPack.TabletPairs * 2;
    }

    public void Visit(Bottle bottle)
    {
        Count += (int)bottle.Items;
    }

    public void Visit(Jar jar)
    {
        Count += jar.Pieces;
    }

    #endregion
}

You moved responsibility of counting number of Pills to class called PillCountVisitor (And we removed switch case statement). That mean's whenever you need to add new type of pill container you should change only PillCountVisitor class. Also notice IVisitor interface is general for using in another scenarios.

By adding Accept method to pill container class:

public class BlisterPack : IAcceptor
{
    public int TabletPairs { get; set; }

    #region IAcceptor Members

    public void Accept(IVisitor visitor)
    {
        visitor.Visit(this);
    }

    #endregion
}

we allow visitor to visit pill container classes.

At the end we calculate pill count using following code:

var visitor = new PillCountVisitor();

foreach (IAcceptor item in packageList)
{
    item.Accept(visitor);
}

That mean's: Every pill container allow the PillCountVisitor visitor to see their pills count. He know how to count your pill's.

At the visitor.Count has the value of pills.

In http://butunclebob.com/ArticleS.UncleBob.IuseVisitor you see real scenario in which you can not use polymorphism (the answer) to follow Single Responsibility Principle. In fact in:

public class HourlyEmployee extends Employee {
  public String reportQtdHoursAndPay() {
    //generate the line for this hourly employee
  }
}

the reportQtdHoursAndPay method is for reporting and representation and this violate the Single Responsibility Principle. So it is better to use visitor pattern to overcome the problem.

For those using anaconda Python:

conda update anaconda

You could use a StringReader and convert the reader to an input stream using the solution in this other stackoverflow post.

You can achieve this with: EventTarget.dispatchEvent(event) and by passing in a new KeyboardEvent as the event.

For example: element.dispatchEvent(new KeyboardEvent('keypress', {'key': 'a'}))

Working example:

// get the element in question_x000D_
const input = document.getElementsByTagName("input")[0];_x000D_
_x000D_
// focus on the input element_x000D_
input.focus();_x000D_
_x000D_
// add event listeners to the input element_x000D_
input.addEventListener('keypress', (event) => {_x000D_
  console.log("You have pressed key: ", event.key);_x000D_
});_x000D_
_x000D_
input.addEventListener('keydown', (event) => {_x000D_
  console.log(`key: ${event.key} has been pressed down`);_x000D_
});_x000D_
_x000D_
input.addEventListener('keyup', (event) => {_x000D_
  console.log(`key: ${event.key} has been released`);_x000D_
});_x000D_
_x000D_
// dispatch keyboard events_x000D_
input.dispatchEvent(new KeyboardEvent('keypress',  {'key':'h'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keydown',  {'key':'e'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keyup', {'key':'y'}));

Consider calling osql.exe (the command line tool for SQL Server) passing as parameter a text file written for each line with the call to the stored procedure.

SQL Server provides some assemblies that could be of use with the name SMO that have seamless integration with PowerShell. Here is an article on that.

http://www.databasejournal.com/features/mssql/article.php/3696731

There are API methods to execute stored procedures that I think are worth being investigated. Here a startup example:

http://www.eggheadcafe.com/software/aspnet/29974894/smo-running-a-stored-pro.aspx

Well, what I do on every project is a mix of the options above.

First, add the jsr310 dependency:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

Important detail: put this dependency on the top of your depedencies list. I already see a project where the Localdate error persists even with this dependency on the pom.xml. But changing the order of the depedency the error was gone.

On your /src/main/resources/application.yml file, setup the write-dates-as-timestamps property:

spring:
  jackson:
    serialization:
      write-dates-as-timestamps: false

And create a ObjectMapper bean as this:

@Configuration
public class WebConfigurer {

    @Bean
    @Primary
    public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
        ObjectMapper objectMapper = builder.build();
        objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        return objectMapper;
    }

}

Following this configuration, the conversion always work on Spring Boot 1.5.x without any error.

Bonus: Spring AMQP Queue configuration

Working with Spring AMQP, pay attention if you have a new instance of Jackson2JsonMessageConverter (common thing when creating a SimpleRabbitListenerContainerFactory). You need to pass the ObjectMapper bean to it, like:

Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter(objectMapper);

Otherwise, you will receive the same error.

1) Delete the pod folder and .xcworkspace file 2) Open the folder in terminal 3) Type "pod install"

Without custom helpers I recommend either ?.Any() ?? false or ?.Any() == true which are relatively concise and only need to specify the sequence once.

When I want to treat a missing collection like an empty one, I use the following extension method:

public static IEnumerable<T> OrEmpty<T>(this IEnumerable<T> sequence)
{
    return sequence ?? Enumerable.Empty<T>();
}

This function can be combined with all LINQ methods and foreach, not just .Any(), which is why I prefer it over the more specialized helper functions people are proposing here.

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

add @PrimaryKey(autoGenerate = true)

@Entity
public class User {

    @PrimaryKey(autoGenerate = true)
    private int id;

    @ColumnInfo(name = "full_name")
    private String name;

    @ColumnInfo(name = "phone")
    private String phone;

    public User(){
    }

    //type-1
    public User(String name, String phone) {
        this.name = name;
        this.phone = phone;
    }

    //type-2
    public User(int id, String name, String phone) {
        this.id = id;
        this.name = name;
        this.phone = phone;
    }

}

while storing data

 //type-1
 db.userDao().InsertAll(new User(sName,sPhone)); 

 //type-2
 db.userDao().InsertAll(new User(0,sName,sPhone)); 

type-1

If you are not passing value for primary key, by default it will 0 or null.

type-2

Put null or zero for the id while creating object (my case user object)

If the field type is long or int (or its TypeConverter converts it to a long or int), Insert methods treat 0 as not-set while inserting the item.

If the field's type is Integer or Long (Object) (or its TypeConverter converts it to an Integer or a Long), Insert methods treat null as not-set while inserting the item.

I've read through all the answers and I'd like to add one more that I think wins out because of its simplicity. Unlike the accepted answer this does not require recursion. It also does not require referencing a FileSystemObject.

Function FileNameFromPath(strFullPath As String) As String

    FileNameFromPath = Right(strFullPath, Len(strFullPath) - InStrRev(strFullPath, "\"))

End Function

http://vba-tutorial.com/parsing-a-file-string-into-path-filename-and-extension/ has this code plus other functions for parsing out the file path, extension and even the filename without the extension.

It may be useful to you to simply increase the number of results that get displayed

In the mongo shell > DBQuery.shellBatchSize = 3000

and then you can select all the results out of the terminal in one go and paste into a text file.

It is what I am going to do :)

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

An Error "indicates serious problems that a reasonable application should not try to catch."

while

An Exception "indicates conditions that a reasonable application might want to catch."

Error along with RuntimeException & their subclasses are unchecked exceptions. All other Exception classes are checked exceptions.

Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException, ParseException, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller

On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything is in order, but they do occur. Examples include ArrayIndexOutOfBoundException, ClassCastException, etc. Many applications will use try-catch or throws clause for RuntimeExceptions & their subclasses but from the language perspective it is not required to do so. Do note that recovery from a RuntimeException is generally possible but the guys who designed the class/exception deemed it unnecessary for the end programmer to check for such exceptions.

Errors are also unchecked exception & the programmer is not required to do anything with these. In fact it is a bad idea to use a try-catch clause for Errors. Most often, recovery from an Error is not possible & the program should be allowed to terminate. Examples include OutOfMemoryError, StackOverflowError, etc.

Do note that although Errors are unchecked exceptions, we shouldn't try to deal with them, but it is ok to deal with RuntimeExceptions(also unchecked exceptions) in code. Checked exceptions should be handled by the code.

One of the usage of nameof keyword is for setting Binding in wpf programmatically.

to set Binding you have to set Path with string, and with nameof keyword, it's possible to use Refactor option.

For example, if you have IsEnable dependency property in your UserControl and you want to bind it to IsEnable of some CheckBox in your UserControl, you can use these two codes:

CheckBox chk = new CheckBox();
Binding bnd = new Binding ("IsEnable") { Source = this };
chk.SetBinding(IsEnabledProperty, bnd);

and

CheckBox chk = new CheckBox();
Binding bnd = new Binding (nameof (IsEnable)) { Source = this };
chk.SetBinding(IsEnabledProperty, bnd);

It's obvious the first code can't refactor but the secend one...

You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.

public String getJSON(String url, int timeout) {
    HttpURLConnection c = null;
    try {
        URL u = new URL(url);
        c = (HttpURLConnection) u.openConnection();
        c.setRequestMethod("GET");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
            case 200:
            case 201:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line+"\n");
                }
                br.close();
                return sb.toString();
        }

    } catch (MalformedURLException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } finally {
       if (c != null) {
          try {
              c.disconnect();
          } catch (Exception ex) {
             Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
          }
       }
    }
    return null;
}

And then you can use returned string with Google Gson to map JSON to object of specified class, like this:

String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);

There is a sample of AuthMsg class:

public class AuthMsg {
    private int code;
    private String message;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
}

JSON returned by http://localhost/authmanager.php must look like this:

{"code":1,"message":"Logged in"}

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

The only thing that worked for me was uninstalling R entirely (make sure to remove it from the Programs files as well), and install it, but unselect Message Translations during the installation process. When I installed R, and subsequently RCmdr, it finally came up in English.

I just had a quick look at your example, but if i understood it the right way you're trying to add 404 routes to dynamic segments. I had the same issue a couple of days ago, found #458 and #1103 and ended up with a hand made check within the render function:

if (!place) return <NotFound />;

hope that helps!

I have had problems with @JodaStephen's implementation on JBoss EAP 6. So, I rewrote the conversion following Oracle's Java Tutorial in http://docs.oracle.com/javase/tutorial/datetime/iso/legacy.html.

    Date input = new Date();
    GregorianCalendar gregorianCalendar = (GregorianCalendar) Calendar.getInstance();
    gregorianCalendar.setTime(input);
    ZonedDateTime zonedDateTime = gregorianCalendar.toZonedDateTime();
    zonedDateTime.toLocalDate();

try as this code.

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: "username="+username+"&email="+email+"&password="+password+"&passconf="+passconf,

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

i think this will work definitely..

you can also use .serialize() function for sending data via jquery Ajax..

i.e: data : $("#registerSubmit").serialize()

Thanks.

You can check this way too

<c:if test="${theBooleanVariable ne true}">It's false!</c:if>

Since id is an attribute don't create an id element, just do this:

myPara.setAttribute("id", "id_you_like");

I think the problem is that you're adding a new entry to the database, but not the data structure that the datagrid represents. You're only querying the database for data in the load event, so if the database changes after that you're not going to know about it.

To solve the problem you need to either re-query the database after each insert, or add the item to tables(0) data structure in addition to the Access table after each insert.

I had a similar problem, I wanted to change the format, but I also wanted the flexibility of being able to change the format in the blade template engine too.

I, therefore, set my model up as the following:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

\Carbon\Carbon::setToStringFormat('d-m-Y');

class User extends Model
{
    protected $dates = [
        'from_date',
    ];
}

The setToStringFormat will set all the dates to use this format for this model.
The advantage of this for me is that I could have the format that I wanted without the mutator, because with the mutator, the attribute is returned as a string meaning that in the blade template I would have to write something like this if I wanted to change the format in the template:

{{ date('Y', strtotime($user->from_date)) }}

Which isn't very clean.

Instead, the attribute is still returned as a Carbon instance, however it is first returned in the desired format.
That means that in the template I could write the following, cleaner, code:

{{ $user->from_date->format('Y') }}

In addition to being able to reformat the Carbon instance, I can also call various Carbon methods on the attribute in the template.

There is probably an oversight to this approach; I'm going to wager it is not a good idea to specify the string format at the top of the model in case it affects other scripts. From what I have seen so far, that has not happened. It has only changed the default Carbon for that model only.

In this instance, it might be a good set the Carbon format back to what it was originally at the bottom of the model script. This is a bodged idea, but it would work for each model to have its own format.
Contrary, if you are having the same format for each model then in your AppServiceProvider instead. That would just keep the code neater and easier to maintain.

iframe is also vulnerable to Cross Frame Scripting:

• https://www.owasp.org/index.php/Cross_Frame_Scripting

PHP is converting null and an empty string automatically to a zero. That happens with modulo as well. Therefor will the code

$number % 2 == 0 or !($number & 1)

with value $number = '' or $number = null result in true. I test it therefor somewhat more extended:

function testEven($pArg){
    if(is_int($pArg) === true){
        $p = ($pArg % 2);
        if($p === 0){
            print "The input '".$pArg."' is even.<br>";
        }else{
            print "The input '".$pArg."' is odd.<br>";
        }
    }else{
        print "The input '".$pArg."' is not a number.<br>";
    }
}

The print is there for testing purposes, hence in practice it becomes:
function testEven($pArg){
    if(is_int($pArg)=== true){
        return $pArg%2;
    }
    return false;
}

This function returns 1 for any odd number, 0 for any even number and false when it is not a number. I always write === true or === false to let myself (and other programmers) know that the test is as intended.

The answer to that can be quite broad.

Essentially, the major difference for me that usually influences my decisions on which to use is that with a SQLDataReader, you are "streaming" data from the database. With a SQLDataAdapter, you are extracting the data from the database into an object that can itself be queried further, as well as performing CRUD operations on.

Obviously with a stream of data SQLDataReader is MUCH faster, but you can only process one record at a time. With a SQLDataAdapter, you have a complete collection of the matching rows to your query from the database to work with/pass through your code.

WARNING: If you are using a SQLDataReader, ALWAYS, ALWAYS, ALWAYS make sure that you write proper code to close the connection since you are keeping the connection open with the SQLDataReader. Failure to do this, or proper error handling to close the connection in case of an error in processing the results will CRIPPLE your application with connection leaks.

Pardon my VB, but this is the minimum amount of code you should have when using a SqlDataReader:

Using cn As New SqlConnection("..."), _
      cmd As New SqlCommand("...", cn)

    cn.Open()
    Using rdr As SqlDataReader = cmd.ExecuteReader()
        While rdr.Read()
            ''# ...
        End While
    End Using
End Using     

equivalent C#:

using (var cn = new SqlConnection("..."))
using (var cmd = new SqlCommand("..."))
{
    cn.Open();
    using(var rdr = cmd.ExecuteReader())
    {
        while(rdr.Read())
        {
            //...
        }
    }
}

This can happen with symlinks sometimes. If you experience this issue and you know you are in an existing directory, but your symlink may have changed, you can use this command:

cd $(pwd)

Bill Horst's - Converting SQL to LINQ is a very good resource for this task (as well as LINQPad).

LINQ Tools has a decent list of tools as well but I do not believe there is anything else out there that can do what Linqer did.

Generally speaking, LINQ is a higher-level querying language than SQL which can cause translation loss when trying to convert SQL to LINQ. For one, LINQ emits shaped results and SQL flat result sets. The issue here is that an automatic translation from SQL to LINQ will often have to perform more transliteration than translation - generating examples of how NOT to write LINQ queries. For this reason, there are few (if any) tools that will be able to reliably convert SQL to LINQ. Analogous to learning C# 4 by first converting VB6 to C# 4 and then studying the resulting conversion.

for (int i = 0; i < list.size(); i++) {
        if (i < list.size() - 1) {
            if (list.get(i) > list.get(i + 1)) {
                int j = list.get(i);
                list.remove(i);
                list.add(i, list.get(i));
                list.remove(i + 1);
                list.add(j);
                i = -1;
            }
        }
    }

Using Private API you can get user phone number on the following way:

extern NSString* CTSettingCopyMyPhoneNumber();


+(NSString *) phoneNumber {
NSString *phone = CTSettingCopyMyPhoneNumber();

return phone;
}

Also include CoreTelephony.framework to your project.

Here it is some code:

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

See more examples in this article, you may need to take a look to impersonation.

In my case, I try to add sudo

sudo nginx -v

Let's look at this with the help of an example. Suppose we have a direct mapped cache and the write back policy is used. So we have a valid bit, a dirty bit, a tag and a data field in a cache line. Suppose we have an operation : write A ( where A is mapped to the first line of the cache).

What happens is that the data(A) from the processor gets written to the first line of the cache. The valid bit and tag bits are set. The dirty bit is set to 1.

Dirty bit simply indicates was the cache line ever written since it was last brought into the cache!

Now suppose another operation is performed : read E(where E is also mapped to the first cache line)

Since we have direct mapped cache, the first line can simply be replaced by the E block which will be brought from memory. But since the block last written into the line (block A) is not yet written into the memory(indicated by the dirty bit), so the cache controller will first issue a write back to the memory to transfer the block A to memory, then it will replace the line with block E by issuing a read operation to the memory. dirty bit is now set to 0.

So write back policy doesnot guarantee that the block will be the same in memory and its associated cache line. However whenever the line is about to be replaced, a write back is performed at first.

A write through policy is just the opposite. According to this, the memory will always have a up-to-date data. That is, if the cache block is written, the memory will also be written accordingly. (no use of dirty bits)

Suppose, for example, that we have a arrays of strings:

String[] strings = {"1", "2", "3"};

With Lambda Expressions ^{[1] [2]} (since Java 8), you can do the next ?:

int[] array = Arrays.asList(strings).stream().mapToInt(Integer::parseInt).toArray();

? This is another way:

int[] array = Arrays.stream(strings).mapToInt(Integer::parseInt).toArray();

There is a constructor for ArrayList which is

ArrayList(Collection<? extends E> c) 

Now, EnumSet extends AbstractCollection so you can just do

ArrayList<Something> all = new ArrayList<Something>(enumSet)

public class Palindromes {
    public static void main(String[] args) {
         String word = "reliefpfpfeiller";
         char[] warray = word.toCharArray(); 
         System.out.println(isPalindrome(warray));       
    }

    public static boolean isPalindrome(char[] word){
        if(word.length%2 == 0){
            for(int i = 0; i < word.length/2-1; i++){
                if(word[i] != word[word.length-i-1]){
                    return false;
                }
            }
        }else{
            for(int i = 0; i < (word.length-1)/2-1; i++){
                if(word[i] != word[word.length-i-1]){
                    return false;
                }
            }
        }
        return true;
    }
}

If you are using version 0.14.0 or higher of the gradle plugin, you should replace "runProguard" with "minifyEnabled" in your build.gradle files.

runProguard was renamed to minifyEnabled in version 0.14.0. For more info, See Android Build System

Create alias in your shell for command with a specified port.

Just set options :

• CURLOPT_HEADER, 0

I met this issue this morning because I used the same executable in DIFFERENT OSes: after compiling my program with gcc -ggdb -Wall test.c -o test in my Mac(10.15.2), I ran gdb with the executable in Ubuntu(16.04) in my VirtualBox.

Fix: recompile with the same command under Ubuntu, then you should be good.

If you are still inside the vi editor, you might be in a different mode from the one you want. Hit ESC a couple of times (until it rings or flashes) and then "i" to enter INSERT mode or "a" to enter APPEND mode (they are the same, just start before or after current character).

If you are back at the command prompt, make sure you can locate the file, then navigate to that directory and perform the mentioned "vi helloWorld.txt". Once you are in the editor, you'll need to check the vi reference to know how to perform the editions you want (you may want to google "vi reference" or "vi cheat sheet").

Once the edition is done, hit ESC again, then type :wq to save your work or :q! to quit without saving.

For quick reference, here you have a text-based cheat sheet.

Another easy way is to use the WC_Product_Factory class and then call function get_product(ID)

http://docs.woothemes.com/wc-apidocs/source-class-WC_Product_Factory.html#16-63

sample:

// assuming the list of product IDs is are stored in an array called IDs;
$_pf = new WC_Product_Factory();  
foreach ($IDs as $id) {

    $_product = $_pf->get_product($id);

    // from here $_product will be a fully functional WC Product object, 
    // you can use all functions as listed in their api
}

You can then use all the function calls as listed in their api: http://docs.woothemes.com/wc-apidocs/class-WC_Product.html

Just using an ALTER TABLE should work. Add the column with the proper type and an IDENTITY flag and it should do the trick

Check out this MSDN article http://msdn.microsoft.com/en-us/library/aa275462(SQL.80).aspx on the ALTER TABLE syntax

You need to add parentheses after a method call, else the compiler will think you're talking about the method itself (a delegate type), whereas you're actually talking about the return value of that method.

string t = obj.getTitle();

Extra Non-Essential Information

Also, have a look at properties. That way you could use title as if it were a variable, while, internally, it works like a function. That way you don't have to write the functions getTitle() and setTitle(string value), but you could do it like this:

public string Title // Note: public fields, methods and properties use PascalCasing
{
    get // This replaces your getTitle method
    {
        return _title; // Where _title is a field somewhere
    }
    set // And this replaces your setTitle method
    {
        _title = value; // value behaves like a method parameter
    }
}

Or you could use auto-implemented properties, which would use this by default:

public string Title { get; set; }

And you wouldn't have to create your own backing field (_title), the compiler would create it itself.

Also, you can change access levels for property accessors (getters and setters):

public string Title { get; private set; }

You use properties as if they were fields, i.e.:

this.Title = "Example";
string local = this.Title;

I don't think that can be done RELIABLY with built in methods on the native Date object. The toLocaleString method gets close, but if I am remembering correctly, it won't work correctly in IE < 10. If you are able to use a library for this task, MomentJS is a really amazing library; and it makes working with dates and times easy. Otherwise, I think you will have to write a basic function to give you the format that you are after.

function formatDate(date) {
    var year = date.getFullYear(),
        month = date.getMonth() + 1, // months are zero indexed
        day = date.getDate(),
        hour = date.getHours(),
        minute = date.getMinutes(),
        second = date.getSeconds(),
        hourFormatted = hour % 12 || 12, // hour returned in 24 hour format
        minuteFormatted = minute < 10 ? "0" + minute : minute,
        morning = hour < 12 ? "am" : "pm";

    return month + "/" + day + "/" + year + " " + hourFormatted + ":" +
            minuteFormatted + morning;
}

When having to fetch multiple collections, you need to:

1. JOIN FETCH one collection
2. Use the Hibernate.initialize for the remaining collections.

So, in your case, you need a first JPQL query like this one:

MyEntity entity = session.createQuery("select e from MyEntity e join fetch e.addreses where e.id 
= :id", MyEntity.class)
.setParameter("id", entityId)
.getSingleResult();

Hibernate.initialize(entity.persons);

This way, you can achieve your goal with 2 SQL queries and avoid a Cartesian Product.

Giving such permission can be dangerous, especially if your web application uses that same username.

Now the web user (and the whole world wide web) also has the permission to create and drop objects within your database. Think SQL Injection!

I recommend granting Execute privileges only to the specific user on the given object as follows:

grant execute on storedProcedureNameNoquotes to myusernameNoquotes

Now the user myusernameNoquotes can execute procedure storedProcedureNameNoquotes without other unnecessary permissions to your valuable data.

I'm using this solution and works in IE8 or greater.

if (typeof Element.prototype.addEventListener === 'undefined') {
    Element.prototype.addEventListener = function (e, callback) {
      e = 'on' + e;
      return this.attachEvent(e, callback);
    };
  }

And then:

<button class="click-me">Say Hello</button>

<script>
  document.querySelectorAll('.click-me')[0].addEventListener('click', function () {
    console.log('Hello');
  });
</script>

This will work both IE8 and Chrome, Firefox, etc.

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Try:

$(document).ready(function() {
    $('#contact-form').validate({submitHandler: function(form) {
         var data = $('#contact-form').serialize();   
         $.post(
              'url_request',
               {data: data},
               function(response){
                  console.log(response);
               }
          );
         }
    });
});

Alternative by terminal with no permission

The pg documentation at NOTES say

The path will be interpreted relative to the working directory of the server process (normally the cluster's data directory), not the client's working directory.

So, gerally, using psql or any client, even in a local server, you have problems ... And, if you're expressing COPY command for other users, eg. at a Github README, the reader will have problems ...

The only way to express relative path with client permissions is using STDIN,

When STDIN or STDOUT is specified, data is transmitted via the connection between the client and the server.

as remembered here:

psql -h remotehost -d remote_mydb -U myuser -c \
   "copy mytable (column1, column2) from STDIN with delimiter as ','" \
   < ./relative_path/file.csv

Consent with @georg-

I would say then why we need lame os.path.join- better to use str.join or unicode.join e.g.

sys.path.append('{0}'.join(os.path.dirname(__file__).split(os.path.sep)[0:-1]).format(os.path.sep))

Or with the power of Java 8 Optional, you also can do such trick:

Optional.ofNullable(boolValue).orElse(false)

:)

You can use the dir step, example:

dir("folder") {
    sh "pwd"
}

The folder can be relative or absolute path.

For npm: you can run:

npm update -g typescript

By default, it will install latest version.

For yarn, you can run:

yarn upgrade typescript

Or you can remove the orginal version, run yarn global remove typescript, and then execute yarn global add typescript, by default it will also install the latest version of typescript.

more details, you can read yarn docs.
