You need the first and last parentheses. Use something like this:

str.indexOf('('); - it will give you first occurrence

str.lastIndexOf(')'); - last one

So you need a string between,

String searchedString = str.substring(str1.indexOf('('),str1.lastIndexOf(')');

Another way to assign a row number in a query is to use the DCount function.

SELECT *, DCount("[ID]","[mytable]","[ID]<=" & [ID]) AS row_id
FROM [mytable]
WHERE row_id=15

You can use Type.GetType(string), but you'll need to know the full class name including namespace, and if it's not in the current assembly or mscorlib you'll need the assembly name instead. (Ideally, use Assembly.GetType(typeName) instead - I find that easier in terms of getting the assembly reference right!)

For instance:

// "I know String is in the same assembly as Int32..."
Type stringType = typeof(int).Assembly.GetType("System.String");

// "It's in the current assembly"
Type myType = Type.GetType("MyNamespace.MyType");

// "It's in System.Windows.Forms.dll..."
Type formType = Type.GetType ("System.Windows.Forms.Form, " + 
    "System.Windows.Forms, Version=2.0.0.0, Culture=neutral, " + 
    "PublicKeyToken=b77a5c561934e089");

AWGN Similar to Matlab Function

def awgn(sinal):
    regsnr=54
    sigpower=sum([math.pow(abs(sinal[i]),2) for i in range(len(sinal))])
    sigpower=sigpower/len(sinal)
    noisepower=sigpower/(math.pow(10,regsnr/10))
    noise=math.sqrt(noisepower)*(np.random.uniform(-1,1,size=len(sinal)))

As @Graham42 noted, mouse option has changed in version 2.1. Scrolling now requires for you to enter copy mode first. To enable scrolling almost identical to how it was before 2.1 add following to your .tmux.conf.

set-option -g mouse on

# make scrolling with wheels work
bind -n WheelUpPane if-shell -F -t = "#{mouse_any_flag}" "send-keys -M" "if -Ft= '#{pane_in_mode}' 'send-keys -M' 'select-pane -t=; copy-mode -e; send-keys -M'"
bind -n WheelDownPane select-pane -t= \; send-keys -M

This will enable scrolling on hover over a pane and you will be able to scroll that pane line by line.

Sanity testing

Sanity testing is the subset of regression testing and it is performed when we do not have enough time for doing testing.

Sanity testing is the surface level testing where QA engineer verifies that all the menus, functions, commands available in the product and project are working fine.

Example

For example, in a project there are 5 modules: Login Page, Home Page, User's Details Page, New User Creation and Task Creation.

Suppose we have a bug in the login page: the login page's username field accepts usernames which are shorter than 6 alphanumeric characters, and this is against the requirements, as in the requirements it is specified that the username should be at least 6 alphanumeric characters.

Now the bug is reported by the testing team to the developer team to fix it. After the developing team fixes the bug and passes the app to the testing team, the testing team also checks the other modules of the application in order to verify that the bug fix does not affect the functionality of the other modules. But keep one point always in mind: the testing team only checks the extreme functionality of the modules, it does not go deep to test the details because of the short time.

Sanity testing is performed after the build has cleared the smoke tests and has been accepted by QA team for further testing. Sanity testing checks the major functionality with finer details.

Sanity testing is performed when the development team needs to know quickly the state of the product after they have done changes in the code, or there is some controlled code changed in a feature to fix any critical issue, and stringent release time-frame does not allow complete regression testing.

Smoke testing

Smoke Testing is performed after a software build to ascertain that the critical functionalities of the program are working fine. It is executed "before" any detailed functional or regression tests are executed on the software build.

The purpose is to reject a badly broken application, so that the QA team does not waste time installing and testing the software application.

In smoke testing, the test cases chosen cover the most important functionalities or components of the system. The objective is not to perform exhaustive testing, but to verify that the critical functionalities of the system are working fine. For example, typical smoke tests would be:

• verify that the application launches successfully,
• Check that the GUI is responsive

Translate composed UInt32 color Value to CSS in .NET

I know the question applies to 3 input values (red green blue). But there may be the situation where you already have a composed 32bit Value. It looks like you want to send the data to some HTML CSS renderer (because of the #HEX format). Actually CSS wants you to print 6 or at least 3 zero filled hex digits here. so #{0:X06} or #{0:X03} would be required. Due to some strange behaviour, this always prints 8 digits instead of 6.

Solve this by:

String.Format("#{0:X02}{1:X02}{2:X02}", (Value & 0x00FF0000) >> 16, (Value & 0x0000FF00) >> 8, (Value & 0x000000FF) >> 0)

They are both rubbish! XCOPY was older and unreliable, so Microsoft replaced it with ROBOCOPY, which is still rubbish.

http://answers.microsoft.com/en-us/windows/forum/windows_8-files/robocopy-appears-to-be-broken-in-windows-8/9a7634c4-3a9d-4f2d-97ae-093002a638a9

Don't worry though, it is a long-standing tradition that was started by the original COPY command, which to this day, still needs the /B switch to get it to actually copy properly!

The collection.count is deprecated, and will be removed in a future version. Use collection.countDocuments or collection.estimatedDocumentCount instead.

userModel.countDocuments(query).exec((err, count) => {
    if (err) {
        res.send(err);
        return;
    }

    res.json({ count: count });
});

If you have 2 beans of the same class autowired to one class you shoud use @Qualifier (Spring Autowiring @Qualifier example).

But it seems like your problem comes from incorrect Java Syntax.

Your object should start with lower case letter

SuggestionService suggestion;

Your setter should start with lower case as well and object name should be with Upper case

public void setSuggestion(final Suggestion suggestion) {
    this.suggestion = suggestion;
}

In C# you can do something like

 String.Format("hello {0}, your age is {1}.",  "John",  29) 

In JavaScript you could do something like

 var x = "hello {0}, your age is {1}";
 x = x.replace(/\{0\}/g, "John");
 x = x.replace(/\{1\}/g, 29);

Nowadays - using C++11 - you can use enum class for this:

enum class Color { RED, BLUE, WHITE };

AFAII this does exactly what you want.

I had have this sort situations when I copied classes from other packages/projects.

Menu->Project->Clean usually helps.

ANSWER: <embed src="https://YOURDOMAIN.com/PAGE.HTM" style="width:100%; height: 50vw;">

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

May be it's good if you define your background-image in the :after pseudo class. Write like this:

.parent{
    width:300px;
    height:300px;
    position:relative;
    border:1px solid red;
}
.parent:after{
    content:'';
    background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
    width:300px;
    height:300px;
    position:absolute;
    top:0;
    left:0;
    opacity:0.5;
}
.child{
    background:yellow;
    position:relative;
    z-index:1;
}

Check this fiddle

You can just use a CheckBox and set its appearance to Button:

CheckBox checkBox = new System.Windows.Forms.CheckBox(); 
checkBox.Appearance = System.Windows.Forms.Appearance.Button; 

counter[row[11]]+=1

You don't show what data is, but apparently when you loop through its rows, row[11] is turning out to be a list. Lists are mutable objects which means they cannot be used as dictionary keys. Trying to use row[11] as a key causes the defaultdict to complain that it is a mutable, i.e. unhashable, object.

The easiest fix is to change row[11] from a list to a tuple. Either by doing

counter[tuple(row[11])] += 1

or by fixing it in the caller before data is passed to medications_minimum3. A tuple simply an immutable list, so it behaves exactly like a list does except you cannot change it once it is created.

Your include produces output, thereby making it impossible to send a http header later. Two option:

1. Move the output somewhere after the include.
2. Use output buffering, i.e. at the very start of your script, put ob_start(), and at the end, put ob_flush(). This enables PHP to first wait for all the output to be gathered, determine in what order to render it, and outputs it.

I would recommend you learn the second option, as it makes you far more flexible.

var attr, object_information='';

for(attr in object){

      //Get names and values of propertys with style (name : value)
      object_information += attr + ' : ' + object[attr] + '\n'; 

   }


alert(object_information); //Show all Object

Properties can't be changed but antContrib vars (http://ant-contrib.sourceforge.net/tasks/tasks/variable_task.html ) can.

Here is a macro to do a find/replace on a var:

    <macrodef name="replaceVarText">
        <attribute name="varName" />
        <attribute name="from" />
        <attribute name="to" />
        <sequential>
            <local name="replacedText"/>
            <local name="textToReplace"/>
            <local name="fromProp"/>
            <local name="toProp"/>
            <property name="textToReplace" value = "${@{varName}}"/>
            <property name="fromProp" value = "@{from}"/>
            <property name="toProp" value = "@{to}"/>

            <script language="javascript">
                project.setProperty("replacedText",project.getProperty("textToReplace").split(project.getProperty("fromProp")).join(project.getProperty("toProp")));
            </script>
            <ac:var name="@{varName}" value = "${replacedText}"/>
        </sequential>
    </macrodef>

Then call the macro like:

<ac:var name="updatedText" value="${oldText}"/>
<current:replaceVarText varName="updatedText" from="." to="_" />
<echo message="Updated Text will be ${updatedText}"/>

Code above uses javascript split then join, which is faster than regex. "local" properties are passed to JavaScript so no property leakage.

It blocks the thread. If you look in Modules/timemodule.c in the Python source, you'll see that in the call to floatsleep(), the substantive part of the sleep operation is wrapped in a Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS block, allowing other threads to continue to execute while the current one sleeps. You can also test this with a simple python program:

import time
from threading import Thread

class worker(Thread):
    def run(self):
        for x in xrange(0,11):
            print x
            time.sleep(1)

class waiter(Thread):
    def run(self):
        for x in xrange(100,103):
            print x
            time.sleep(5)

def run():
    worker().start()
    waiter().start()

Which will print:

>>> thread_test.run()
0
100
>>> 1
2
3
4
5
101
6
7
8
9
10
102

I can see that your using AppServ, mod_rewrite is disabled by default on that WAMP package (just googled it)

Solution:

Find: C:/AppServ/Apache/conf/httpd.conf file.

and un-comment this line #LoadModule rewrite_module modules/mod_rewrite.so

Restart apache... Simplez

EDIT: This is an extremely primitive answer but I can't delete it because it was accepted. See the answers below for a better solution though

Why not just generate a whitespace string dynamically to insert into the statement.

So if you want them all to start on the 50th character...

String key = "Name =";
String space = "";
for(int i; i<(50-key.length); i++)
{space = space + " ";}
String value = "Bob\n";
System.out.println(key+space+value);

Put all of that in a loop and initialize/set the "key" and "value" variables before each iteration and you're golden. I would also use the StringBuilder class too which is more efficient.

Using a text editor, check for ^M (control-M, or carriage return) at the end of each line. You will need to remove them first, then append the additional text at the end of the line.

sed -i 's|^M||g' ips.txt
sed -i 's|$|:80|g' ips.txt

This is not the exact answer to this question, but those who are not able to find setting popup. Their is two ways to open setting pop up.

My solution handles quotes, overriding field and string separators, etc. It is short and sweet.

    public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')
    {
        bool bolQuote = false;
        StringBuilder bld = new StringBuilder();
        List<string> retAry = new List<string>();

        foreach (char c in r.ToCharArray())
            if ((c == fieldSep && !bolQuote))
            {
                retAry.Add(bld.ToString());
                bld.Clear();
            }
            else
                if (c == stringSep)
                    bolQuote = !bolQuote;
                else
                    bld.Append(c);

        return retAry.ToArray();
    }

In my case, I was using a special character in my app file path. I closed the Android Studio and removed the ' character from my app file path. Everything worked fine when I reopned the project.

you need to include the Wordpress loop in your search.php this is example

search.php template file:

<?php get_header(); ?>
<?php
$s=get_search_query();
$args = array(
                's' =>$s
            );
    // The Query
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) {
        _e("<h2 style='font-weight:bold;color:#000'>Search Results for: ".get_query_var('s')."</h2>");
        while ( $the_query->have_posts() ) {
           $the_query->the_post();
                 ?>
                    <li>
                        <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                    </li>
                 <?php
        }
    }else{
?>
        <h2 style='font-weight:bold;color:#000'>Nothing Found</h2>
        <div class="alert alert-info">
          <p>Sorry, but nothing matched your search criteria. Please try again with some different keywords.</p>
        </div>
<?php } ?>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Use Invoke-RestMethod to consume REST-APIs. Save the JSON to a string and use that as the body, ex:

$JSON = @'
{"@type":"login",
 "username":"[email protected]",
 "password":"yyy"
}
'@

$response = Invoke-RestMethod -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you use Powershell 3, I know there have been some issues with Invoke-RestMethod, but you should be able to use Invoke-WebRequest as a replacement:

$response = Invoke-WebRequest -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you don't want to write your own JSON every time, you can use a hashtable and use PowerShell to convert it to JSON before posting it. Ex.

$JSON = @{
    "@type" = "login"
    "username" = "[email protected]"
    "password" = "yyy"
} | ConvertTo-Json

I solved a similar problem, where I wanted to find a book by its isbnCode not by your id(primary key).

@Entity
public class Book implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;
    private String isbnCode;

...

In the repository the method was created like @kamalveer singh mentioned. Note that the method name is findBy+fieldName (in my case: findByisbnCode):

@Repository
public interface BookRepository extends JpaRepository<Book, Integer> {

    Book findByisbnCode(String isbnCode);
}

Then, implemented the method in the service:

@Service
public class BookService {

    @Autowired
    private BookRepository repo;
    
    
    public Book findByIsbnCode(String isbnCode) {
        Book obj = repo.findByisbnCode(isbnCode);
        return obj; 
    }
}

There's no built-in option for this (and I don't think it's all that useful either), but it is possible to do this in git, with the help of an "external diff" script.

Here's a pretty crappy one; it will be up to you to fix up the output the way you would like it.

#! /bin/sh
#
# run this with:
#    GIT_EXTERNAL_DIFF=<name of script> git diff ...
#
case $# in
1) "unmerged file $@, can't show you line numbers"; exit 1;;
7) ;;
*) echo "I don't know what to do, help!"; exit 1;;
esac

path=$1
old_file=$2
old_hex=$3
old_mode=$4
new_file=$5
new_hex=$6
new_mode=$7

printf '%s: ' $path
diff $old_file $new_file | grep -v '^[<>-]'

For details on "external diff" see the description of GIT_EXTERNAL_DIFF in the git manual page (around line 700, pretty close to the end).

Populate the text box values in the Page Init event as opposed to using the Postback.

protected void Page_Init(object sender, EventArgs e)
{
    DropDownTitle();
}

Am I getting it because the act of calling it via e.extractAll("th") also passes in self as an argument?

Yes, that's precisely it. If you like, the first parameter is the object name, e that you are calling it with.

And if so, by removing the self in the call, would I be making it some kind of class method that can be called like Extractor.extractAll("th")?

Not quite. A classmethod needs the @classmethod decorator, and that accepts the class as the first paramater (usually referenced as cls). The only sort of method that is given no automatic parameter at all is known as a staticmethod, and that again needs a decorator (unsurprisingly, it's @staticmethod). A classmethod is used when it's an operation that needs to refer to the class itself: perhaps instantiating objects of the class; a staticmethod is used when the code belongs in the class logically, but requires no access to class or instance.

But yes, both staticmethods and classmethods can be called by referencing the classname as you describe: Extractor.extractAll("th").

Another simple solution is to use map() as follows:

tensor_shape = map(int, my_tensor.shape)

This converts all the Dimension objects to int

You can use this command

$ git rev-list HEAD

You can also use the head Unix command to show the latest n HEAD commits like

$ git rev-list HEAD | head - 2

If the sent_at field is not there when its not set then:

db.emails.count({sent_at: {$exists: false}})

If its there and null, or not there at all:

db.emails.count({sent_at: null})

Refer here for querying and null

you can not do it in this way

Use the following instead

typedef struct
{
   int id;
   char* name;
}employee;

employee emp = {
.id = 0, 
.name = "none"
};

You can use macro to define and initialize your instances. this will make easiier to you each time you want to define new instance and initialize it.

typedef struct
{
   int id;
   char* name;
}employee;

#define INIT_EMPLOYEE(X) employee X = {.id = 0, .name ="none"}

and in your code when you need to define new instance with employee type, you just call this macro like:

INIT_EMPLOYEE(emp);

This question will get moved but you can do the following

which javac

or

cd /
find . -name 'javac'

In addition to everything else that has been said, you can call DefaultIfEmpty() before you call Single(). This will ensure that your sequence contains something and thereby averts the InvalidOperationException "Sequence contains no elements". For example:

BlogPost post = (from p in dc.BlogPosts
                 where p.BlogPostID == ID
                 select p).DefaultIfEmpty().Single();

This is the way to dynamically set the value

var jsonVariable = {};
for (var i = 1; i < 3; i++) {
    var jsonKey = i + 'name';
    jsonVariable[jsonKey] = 'name' + i;
}

Every class file starts with the hex value 0xCAFEBABE to identify it as valid JVM bytecode.

An short and easy way to change color of option menu index icon is:

<!-- android:textColorSecondary is the color of the menu overflow icon (three vertical dots) -->
<item name="android:textColorSecondary">@color/optionMenuIconColor</item>

Add above line of code into style.xml (custom theme) file, Hope you get answer,Thanks.

To create the regex from a string, you have to use JavaScript's RegExp object.

If you also want to match/replace more than one time, then you must add the g (global match) flag. Here's an example:

var stringToGoIntoTheRegex = "abc";
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

In the general case, escape the string before using as regex:

Not every string is a valid regex, though: there are some speciall characters, like ( or [. To work around this issue, simply escape the string before turning it into a regex. A utility function for that goes in the sample below:

function escapeRegExp(stringToGoIntoTheRegex) {
    return stringToGoIntoTheRegex.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}

var stringToGoIntoTheRegex = escapeRegExp("abc"); // this is the only change from above
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

Note: the regex in the question uses the s modifier, which didn't exist at the time of the question, but does exist -- a s (dotall) flag/modifier in JavaScript -- today.

Both std::string and std::vector<T> have constructors initializing the object to be empty. You could use std::vector<unsigned char>() but I'd remove the initializer.

The generic Returns<T> method can handle this situation nicely.

_mock.Setup(x => x.DoSomething(It.IsAny<string>())).Returns<string>(x => x);

Or if the method requires multiple inputs, specify them like so:

_mock.Setup(x => x.DoSomething(It.IsAny<string>(), It.IsAny<int>())).Returns((string x, int y) => x);

There are also the rows and cells members;

var t = document.getElementById("tbl");
for (var r = 0; r < t.rows.length; r++) {
    for (var c = 0; c < t.rows[r].cells.length; c++) {
        alert(t.rows[r].cells[c].innerHTML)
    }
}

Here is a simple programe to capture a image from using laptop default camera.I hope that this will be very easy method for all.

import cv2

video = cv2.VideoCapture(0) 
# 2. Variable
a = 0
# 3. While loop
while True:
    a = a + 1
    # 4.Create a frame object
    check, frame = video.read()
    # Converting to grayscale
    #gray = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    # 5.show the frame!
    cv2.imshow("Capturing",frame)
    # 6.for playing 
    key = cv2.waitKey(1)
    if key == ord('q'):
        break
# 7. image saving
showPic = cv2.imwrite("filename.jpg",frame)
print(showPic)
# 8. shutdown the camera
video.release()
cv2.destroyAllWindows

This is a simpler way using iloc to select which columns to sum:

df['f']=df.iloc[:,0:2].sum(axis=1)
df['g']=df.iloc[:,[0,1]].sum(axis=1)
df['h']=df.iloc[:,[0,3]].sum(axis=1)

Produces:

   a  b   c  d   e  f  g   h
0  1  2  dd  5   8  3  3   6
1  2  3  ee  9  14  5  5  11
2  3  4  ff  1   8  7  7   4

I can't find a way to combine a range and specific columns that works e.g. something like:

df['i']=df.iloc[:,[[0:2],3]].sum(axis=1)
df['i']=df.iloc[:,[0:2,3]].sum(axis=1)

That's a good question, but I think you just misunderstand what you read.

Install PDO

The ./config --with-pdo-mysql is something you have to put on only if you compile your own PHP code. If you install it with package managers, you just have to use the command line given by Jany Hartikainen: sudo apt-get install php5-mysql and also sudo apt-get install pdo-mysql

Compatibility with mysql_

Apart from the fact mysql_ is really discouraged, they are both independent. If you use PDO mysql_ is not implicated, and if you use mysql_ PDO is not required.

If you turn off PDO without changing any line in your code, you won't have a problem. But since you started to connect and write queries with PDO, you have to keep it and give up mysql_.

Several years ago the MySQL team published a script to migrate to MySQLi. I don't know if it can be customised, but it's official.

From the manual:

SET NAMES indicates what character set the client will use to send SQL statements to the server.

More elaborately, (and once again, gratuitously lifted from the manual):

SET NAMES indicates what character set the client will use to send SQL statements to the server. Thus, SET NAMES 'cp1251' tells the server, “future incoming messages from this client are in character set cp1251.” It also specifies the character set that the server should use for sending results back to the client. (For example, it indicates what character set to use for column values if you use a SELECT statement.)

Trying to get an autoplaying video to loop by calling play() when it ends, the timeout workaround did not work for me (however long the timeout is).

But I discovered that by cloning/replacing the video with jQuery when it ended, it would loop properly.

For example:

<div class="container">
  <video autoplay>
    <source src="video.mp4" type="video/mp4">
  </video>
</div>

and

$(document).ready(function(){
  function bindReplay($video) {
    $video.on('ended', function(e){
      $video.remove();
      $video = $video.clone();
      bindReplay($video);
      $('.container').append($video);
    });
  }
  var $video = $('.container video');
  bindReplay($video);
});

I'm using Chrome 54.0.2840.59 (64-bit) / OS X 10.11.6

I would use Pandas with col number

f = pd.read_csv("test.csv", usecols=[0,1,3,4])

f.to_csv("test.csv", index=False)

The simplest by far will be Simple http://simple.sourceforge.net, you only need to annotate a single object like so

@Root
public class Entry {

   @Attribute
   private String a
   @Attribute
   private int b;
   @Element
   private Date c;

   public String getSomething() {
      return a;
   }
} 

@Root
public class Configuration {

   @ElementList(inline=true)
   private List<Entry> entries;

   public List<Entry> getEntries() { 
      return entries;
   }
}

Then all you have to do to read the whole file is specify the location and it will parse and populate the annotated POJO's. This will do all the type conversions and validation. You can also annotate for persister callbacks if required. Reading it can be done like so.

Serializer serializer = new Persister();
Configuration configuraiton = serializer.read(Configuration.class, fileLocation);

function datesEqual(a, b)
{
   return (!(a>b || b>a))
}

You could switch the onClick event handler on the button to an onSubmit handler on the form:

render : function() {
      return (
        <form onSubmit={this.handleLogin}>
          <input type="text" name="email" placeholder="Email" />
          <input type="password" name="password" placeholder="Password" />
          <button type="submit">Login</button>
        </form>
      );
    },

Then you can make use of FormData to parse the form (and construct a JSON object from its entries if you want).

handleLogin: function(e) {
   const formData = new FormData(e.target)
   const user = {}

   e.preventDefault()

   for (let entry of formData.entries()) {
       user[entry[0]] = entry[1]
   }

   // Do what you will with the user object here
}

Idle Timeout is if no action has been asked from your web app, it the process will drop and release everything from memory

Recycle is a forced action on the application where your processed is closed and started again, for memory leaking purposes and system health

The negative impact of both is usually the use of your Session and Application state is lost if you mess with Recycle to a faster time.(logged in users etc will be logged out, if they where about to "check out" all would have been lost" that's why recycle is at such a large time out value, idle timeout doesn't matter because nobody is logged in anyway and figure 20 minutes an no action they are not still "shopping"

The positive would be get rid of the idle time out as your website will respond faster on its "first" response if its not a highly active site where a user would have to wait for it to load if you have 1 user every 20 minutes lets say. So a website that get his less then 1 time in 20 minutes actually you would want to increase this value as the website has to load up again from scratch for each user. but if you set this to 0 over a long time, any memory leaks in code could over a certain amount of time, entirely take over the server.

I do this using associative arrays since bash 4 and setting IFS to a value that can be defined manually.

The purpose of this approach is to have arrays as values of associative array keys.

In order to set IFS back to default just unset it.

• unset IFS

This is an example:

#!/bin/bash

set -euo pipefail

# used as value in asscciative array
test=(
  "x3:x4:x5"
)
# associative array
declare -A wow=(
  ["1"]=$test
  ["2"]=$test
)
echo "default IFS"
for w in ${wow[@]}; do
  echo "  $w"
done

IFS=:
echo "IFS=:"
for w in ${wow[@]}; do
  for t in $w; do
    echo "  $t"
  done
done
echo -e "\n or\n"
for w in ${!wow[@]}
do
  echo "  $w"
  for t in ${wow[$w]}
  do
    echo "    $t"
  done
done

unset IFS
unset w
unset t
unset wow
unset test

The output of the script below is:

default IFS
  x3:x4:x5
  x3:x4:x5
IFS=:
  x3
  x4
  x5
  x3
  x4
  x5

 or

  1
    x3
    x4
    x5
  2
    x3
    x4
    x5

I tried the following code in pom.xml and it worked for me

<build>

1. Install Java 7u21 from here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u21-oth-JPR

2. set these variables:

   export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home"
   export PATH=$JAVA_HOME/bin:$PATH
   

3. Run your app and fun :)

(Minor update: put variable value in quote)

This is the only one that actually worked for me in all the browsers

let newTab = window.open(); newTab.location.href = url;

Dont use spaces:

SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%
PAUSE

Do you need to retrieve the object even after the application shutting donw or just during it's running ?

You can store it into a database.
Or Simply create a custom Application class.

public class MyApplication extends Application {

    private static Object mMyObject;
    // static getter & setter
    ...
}

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application ... android:name=".MyApplication">
        <activity ... />
        ...
    </application>
    ...
</manifest>

And then from every activities do :

((MyApplication) getApplication).getMyObject();

Not really the best way but it works.

Try http://php.net/manual/en/curl.examples-basic.php :)

<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

As the documentation says:

The basic idea behind the cURL functions is that you initialize a cURL session using the curl_init(), then you can set all your options for the transfer via the curl_setopt(), then you can execute the session with the curl_exec() and then you finish off your session using the curl_close().

If there are no typos in the question, you got the conditions wrong:

You said this:

IF cells (i,"A") contains the text 'Miami'

...but your code says:

If Cells(i, "A") <> "Miami"

--> <> means that the value of the cell is not equal to "Miami", so you're not checking what you think you are checking.

I guess you want this instead:

If Cells(i, "A") like "*Miami*"

EDIT:

Sorry, but I can't really help you more. As I already said in a comment, I'm no Excel VBA expert.
Normally I would open Excel now and try your code myself, but I don't even have Excel on any of my machines at home (I use OpenOffice).

Just one general thing: can you identify the row that does not work?
Maybe this helps someone else to answer the question.

Does it ever execute (or at least try to execute) the Cells(i, "C").Value = "BA" line?
Or is the If Cells(i, "A") like "*Miami*" stuff already False?
If yes, try checking just one cell and see if that works.

Change var data = 'id='+ id & 'name='+ name; as below,

use this instead.....

var data = "id="+ id + "&name=" + name;

this will going to work fine:)

I know the question is about GCC, but I thought it might be useful to have some information about compilers other compilers as well.

GCC's noinline function attribute is pretty popular with other compilers as well. It is supported by at least:

• Clang (check with __has_attribute(noinline))
• Intel C/C++ Compiler (their documentation is terrible, but I'm certain it works on 16.0+)
• Oracle Solaris Studio back to at least 12.2
• ARM C/C++ Compiler back to at least 4.1
• IBM XL C/C++ back to at least 10.1
• TI 8.0+ (or 7.3+ with --gcc, which will define __TI_GNU_ATTRIBUTE_SUPPORT__)

Additionally, MSVC supports __declspec(noinline) back to Visual Studio 7.1. Intel probably supports it too (they try to be compatible with both GCC and MSVC), but I haven't bothered to verify that. The syntax is basically the same:

__declspec(noinline)
static void foo(void) { }

PGI 10.2+ (and probably older) supports a noinline pragma which applies to the next function:

#pragma noinline
static void foo(void) { }

TI 6.0+ supports a FUNC_CANNOT_INLINE pragma which (annoyingly) works differently in C and C++. In C++, it's similar to PGI's:

#pragma FUNC_CANNOT_INLINE;
static void foo(void) { }

In C, however, the function name is required:

#pragma FUNC_CANNOT_INLINE(foo);
static void foo(void) { }

Cray 6.4+ (and possibly earlier) takes a similar approach, requiring the function name:

#pragma _CRI inline_never foo
static void foo(void) { }

Oracle Developer Studio also supports a pragma which takes the function name, going back to at least Forte Developer 6, but note that it needs to come after the declaration, even in recent versions:

static void foo(void);
#pragma no_inline(foo)

Depending on how dedicated you are, you could create a macro that would work everywhere, but you would need to have the function name as well as the declaration as arguments.

If, OTOH, you're okay with something that just works for most people, you can get away with something which is a little more aesthetically pleasing and doesn't require repeating yourself. That's the approach I've taken for Hedley, where the current version of HEDLEY_NEVER_INLINE looks like:

#if \
  HEDLEY_GNUC_HAS_ATTRIBUTE(noinline,4,0,0) || \
  HEDLEY_INTEL_VERSION_CHECK(16,0,0) || \
  HEDLEY_SUNPRO_VERSION_CHECK(5,11,0) || \
  HEDLEY_ARM_VERSION_CHECK(4,1,0) || \
  HEDLEY_IBM_VERSION_CHECK(10,1,0) || \
  HEDLEY_TI_VERSION_CHECK(8,0,0) || \
  (HEDLEY_TI_VERSION_CHECK(7,3,0) && defined(__TI_GNU_ATTRIBUTE_SUPPORT__))
#  define HEDLEY_NEVER_INLINE __attribute__((__noinline__))
#elif HEDLEY_MSVC_VERSION_CHECK(13,10,0)
#  define HEDLEY_NEVER_INLINE __declspec(noinline)
#elif HEDLEY_PGI_VERSION_CHECK(10,2,0)
#  define HEDLEY_NEVER_INLINE _Pragma("noinline")
#elif HEDLEY_TI_VERSION_CHECK(6,0,0)
#  define HEDLEY_NEVER_INLINE _Pragma("FUNC_CANNOT_INLINE;")
#else
#  define HEDLEY_NEVER_INLINE HEDLEY_INLINE
#endif

If you don't want to use Hedley (it's a single public domain / CC0 header) you can convert the version checking macros without too much effort, but more than I'm willing to put in ?.

Iv'e fixed/improved Tomalak's answer with:

• Make an Array only if needed.
• If there's another equation symbol in the value it gets inside the value
• It now uses the location.search value instead of a url.
• Empty search string results in an empty object.

Code:

function getSearchObject() {
    if (location.search === "") return {};

    var o = {},
        nvPairs = location.search.substr(1).replace(/\+/g, " ").split("&");

    nvPairs.forEach( function (pair) {
        var e = pair.indexOf('=');
        var n = decodeURIComponent(e < 0 ? pair : pair.substr(0,e)),
            v = (e < 0 || e + 1 == pair.length) 
                ? null : 
                decodeURIComponent(pair.substr(e + 1,pair.length - e));
        if (!(n in o))
            o[n] = v;
        else if (o[n] instanceof Array)
            o[n].push(v);
        else
            o[n] = [o[n] , v];
    });
    return o;
}

private static void generateFile(String stringToWrite, String outputFile) {
    try {       
        FileWriter writer = new FileWriter(outputFile);
        writer.append(stringToWrite);
        writer.flush();
        writer.close();
        log.debug("New File is generated ==>"+outputFile);
    } catch (Exception exp) {
        log.error("Exception in generateFile ", exp);
    }
}

If you really need to get it back into an array I find it easiest to convert the array to a list, expand the list then convert it back to an array.

        string[] myArray = new string[1] {"Element One"};
        // Convert it to a list
        List<string> resizeList = myArray.ToList();
        // Add some elements
        resizeList.Add("Element Two");
        // Back to an array
        myArray = resizeList.ToArray();
        // myArray has grown to two elements.

This way added by Sebastiano was OK, but it's necessary, when you run tests from i.e. IntelliJ IDE to add:

 try {
    // clearing app data
    Runtime runtime = Runtime.getRuntime();
    runtime.exec("adb shell pm clear YOUR_APP_PACKAGE_GOES HERE");

}

instead of only "pm package..."

and more important: add it before driver.setCapability(App_package, package_name).

i like to use a littly tiny library called class-transformer.

it can handle nested-objects, map strings to date-objects and handle different json-property-names a lot more.

Maybe worth a look.

import { Type, plainToClass, Expose } from "class-transformer";
import 'reflect-metadata';

export class Employee{
    @Expose({ name: "uid" })
    id: number;

    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;

    @Type(() => Permission)
    permissions: Permission[] = [];
    typeOfEmployee: string;
    note: string;

    @Type(() => Date)
    lastUpdate: Date;
}

export class Permission {
  type : string;
}

let json:string = {
    "uid": 123,
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 1,
    "username": "<anystring>",
    "permissions": [
      {'type' : 'read'},
      {'type' : 'write'}
    ],
    "lastUpdate": "2020-05-08"
}

console.log(plainToClass(Employee, json));

```

Take a look at CBFG and the Android port of the loading/rendering code. You should be able to drop the code into your project and use it straight away.

Whitespace just means characters which are used for spacing, and have an "empty" representation. In the context of python, it means tabs and spaces (it probably also includes exotic unicode spaces, but don't use them). The definitive reference is here: http://docs.python.org/2/reference/lexical_analysis.html#indentation

I'm not sure exactly how to use it.

Put it at the front of the line you want to indent. If you mix spaces and tabs, you'll likely see funky results, so stick with one or the other. (The python community usually follows PEP8 style, which prescribes indentation of four spaces).

You need to create a new indent level after each colon:

for x in range(0, 50):
    print x
    print 2*x

print x

In this code, the first two print statements are "inside" the body of the for statement because they are indented more than the line containing the for. The third print is outside because it is indented less than the previous (nonblank) line.

If you don't indent/unindent consistently, you will get indentation errors. In addition, all compound statements (i.e. those with a colon) can have the body supplied on the same line, so no indentation is required, but the body must be composed of a single statement.

Finally, certain statements, like lambda feature a colon, but cannot have a multiline block as the body.

I would counsel against using if ($hash{$key}) since it will not do what you expect if the key exists but its value is zero or empty.

Git pull is actually a combo tool: it runs git fetch (getting the changes) and git merge (merging them with your current copy)

Are you sure you are on the correct branch?

text.setTextColor(getResource().getColor(R.color.black)) you have create black color in color.xml.

OR

text.setTextColor(Color.parseColor("#000000")) here type desired hexcode

OR

text.setTextColor(Color.BLACK) you can use static color fields

The code creates an anonymous function, and then immediately runs it. Similar to:

var temp = function() {
  // init part
}
temp();

The purpose of this construction is to create a scope for the code inside the function. You can declare varaibles and functions inside the scope, and those will be local to that scope. That way they don't clutter up the global scope, which minimizes the risk for conflicts with other scripts.

Try this: jdbc:oracle:thin:@oracle.hostserver2.mydomain.ca:1522/ABCD

For an app created with create-react-app I managed to see the version:

1. Open Chrome Dev Tools / Firefox Dev Tools,
2. Search and open main.XXXXXXXX.js file where XXXXXXXX is a builds hash /could be different,
3. Optional: format source by clicking on the {} to show the formatted source,
4. Search as text inside the source for react-dom,
5. in Chrome was found: "react-dom": "^16.4.0",
6. in Firefox was found: 'react-dom': '^16.4.0'

The app was deployed without source map.

If you're attempting to do this in a .NET Standard library, here's a simple solution, with all of the risks of just returning true in your handler. I leave safety up to you.

var handler = new HttpClientHandler();
handler.ClientCertificateOptions = ClientCertificateOption.Manual;
handler.ServerCertificateCustomValidationCallback = 
    (httpRequestMessage, cert, cetChain, policyErrors) =>
{
    return true;
};

var client = new HttpClient(handler);

In bootstrap 4.3.1 I can change the background color of the toggler icon to white via the css code.

.navbar-toggler{
  background-color:white;
  }

And in my opinion the so changed icon looks fine as well on light as on dark background.

If you got a Apache Maven project, it's easy to use this package in your project. Just specify it in your pom.xml:

<project>
...

    <properties>
        <version.commons-io>2.4</version.commons-io>
    </properties>

    <dependencies>
        <dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>${version.commons-io}</version>
        </dependency>
    </dependencies>

...
</project>

On Debian 7 Wheezy, I had to do:

pip install --upgrade dnspython

even if python-dns package was installed.

Update 2019/04/16: It seems copy/paste is now officially supported in Windows build >= 17643. Take a look at Rich Turner's answer. This can be enabled through the same settings menu described below by clicking the checkbox next to "Use Ctrl+Shift+C/V as Copy/Paste".

Another solution would be to enable "QuickEdit Mode" and then you can paste by right-clicking in the terminal.

To enable QuickEdit Mode, right-click on the toolbar (or simply click on the icon in the upper left corner), select Properties, and in the Options tab, click the checkbox next to QuickEdit Mode.

With this mode enabled, you can also copy text in the terminal by clicking and dragging. Once a selection is made, you can press Enter or right-click to copy.

First of all, two things that we need to understand,

Client

• It makes request to a specific server

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handles the request of the client and makes replica of its own which is private to client only who send request and this raplica of server runs on different thread.

Now at client side, how to access all the methods of server?

• Server sends response with IBinder Object. So, IBinder object is our handler which accesses all the methods of Service by using (.) operator.

.

MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder binder) {
        Log.d("ServiceConnection","connected");
        myService = binder;
    }
    //binder comes from server to communicate with method's of 

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
}

Now how to call method which lies in service

myservice.serviceMethod();

Here myService is object and serviceMethod is method in service. and by this way communication is established between client and server.

I downloaded and installed the JDK 1.7 from Oracle. In the console / in Terminal Java 7 works fine.

When I start a Java program (like Eclipse) via the GUI, I get:

To open "Eclipse.app" you need a Java SE 6 runtime. Would you like to install one now?

Because I did not want to install old Java version, I used the following workaround:

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

Credits to monkehWorks.

int keyIndex = Array.FindIndex(words, w => w.IsKey);

That actually gets you the integer index and not the object, regardless of what custom class you have created

Too bad we're kind of forced to tell the compiler the obvious:

Subclass(): base() {}
Subclass(int x): base(x) {}
Subclass(int x,y): base(x,y) {}

I only need to do 3 constructors in 12 subclasses, so it's no big deal, but I'm not too fond of repeating that on every subclass, after being used to not having to write it for so long. I'm sure there's a valid reason for it, but I don't think I've ever encountered a problem that requires this kind of restriction.

In addition, if you are using Tern eclipse IDE or IBM Node.js Tools for Eclipse, you may need to disable JSHint and other libraries that you don't want.

To disable this, Project Properties > Tern > Modules > JSHint or any other library that you don't want.

It should just be

this way:

   SELECT * FROM table1 USE INDEX (col1_index,col2_index)
    WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM table1 IGNORE INDEX (col3_index)
WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM t1 USE INDEX (i1) IGNORE INDEX (i2) USE INDEX (i2);

And many more ways check this

Do I need to explicitly specify?

• No, no Need to specify explicitly.
• DB engine should automatically select the index to use based on query execution plans it builds from @Tudor Constantin answer.
• The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index. from @niktrl answer

I just developed a javascript library called JIC to solve that problem. It allows you to compress jpg and png on the client side 100% with javascript and no external libraries required!

You can try the demo here : http://makeitsolutions.com/labs/jic and get the sources here : https://github.com/brunobar79/J-I-C

Since this question is still getting a lot of attention, I decided to answer it by copying this answer from Code Review.SE:

You're following the same philosophy as the bubble sort, which is very, very, very slow. Have you tried this?:

• Sort your unordered array with quicksort. Quicksort is much faster than bubble sort (I know, you are not sorting, but the algorithm you follow is almost the same as bubble sort to traverse the array).

• Then start removing duplicates (repeated values will be next to each other). In a for loop you could have two indices: source and destination. (On each loop you copy source to destination unless they are the same, and increment both by 1). Every time you find a duplicate you increment source (and don't perform the copy). @morgano

I have a more general answer; but I believe it is useful for counting the columns for all tables in a DB:

SELECT table_name, count(*)
FROM information_schema.columns
GROUP BY table_name;

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

One is a column (aka Series), while the other is a DataFrame:

In [1]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])

In [2]: df
Out[2]:
   a  b
0  1  2
1  3  4

The column 'b' (aka Series):

In [3]: df['b']
Out[3]:
0    2
1    4
Name: b, dtype: int64

The subdataframe with columns (position) in [1]:

In [4]: df[[1]]
Out[4]:
   b
0  2
1  4

Note: it's preferable (and less ambiguous) to specify whether you're talking about the column name e.g. ['b'] or the integer location, since sometimes you can have columns named as integers:

In [5]: df.iloc[:, [1]]
Out[5]:
   b
0  2
1  4

In [6]: df.loc[:, ['b']]
Out[6]:
   b
0  2
1  4

In [7]: df.loc[:, 'b']
Out[7]:
0    2
1    4
Name: b, dtype: int64

this is a sample of one of my app how i handle

 //searching for the Edit Text in the view    
    final EditText myEditText =(EditText)view.findViewById(R.id.myEditText);
        myEditText.setOnKeyListener(new View.OnKeyListener() {
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                 if (event.getAction() == KeyEvent.ACTION_DOWN)
                      if ((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) ||
                             (keyCode == KeyEvent.KEYCODE_ENTER)) {
                                //do something
                                //true because you handle the event
                                return true;
                               }
                       return false;
                       }
        });

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

One thing not mentioned in other answers is checking the text size. It is often needed to make sure the text fits the image (e.g. shorten the text if oversized) or to determine location to draw the text (e.g. aligned text top center). Pillow/PIL offers two methods to check the text size, one via ImageFont and one via ImageDraw. As shown below, the font doesn't handle multiple lined, while ImageDraw does.

In [28]: im = Image.new(mode='RGB',size=(240,240))                                                            
In [29]: font = ImageFont.truetype('arial')
In [30]: draw = ImageDraw.Draw(im)
In [31]: t1 = 'hello world!'
In [32]: t2 = 'hello \nworld!'
In [33]: font.getsize(t1), font.getsize(t2) # the height is the same
Out[33]: ((52, 10), (60, 10)) 
In [35]: draw.textsize(t1, font), draw.textsize(t2, font)  # handles multi-lined text
Out[35]: ((52, 10), (27, 24)) 

I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.

However, I fortunately came across the following:

Rahul's blog

which informs that servicemodelreg also needs to be run:

Run Visual Studio 2008 Command Prompt as “Administrator”. Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. Run this command servicemodelreg –i.

Some googling led me to the following post:

http://www.developerweb.net/forum/showthread.php?t=3434

The code provided in the post is in C, but it shouldn't be too hard to rewrite it to Java.

I originally asked this question I was looking for a Chrome (or FireFox) solution, but I stumbled across this feature in Internet Explorer developer tools. Pretty much what I'm looking for (except for the javascript)

Result:

To stop a service, you have to find service name using:

adb shell dumpsys activity services <your package>

for example: adb shell dumpsys activity services com.xyz.something

This will list services running for your package.
Output should be similar to:

ServiceRecord{xxxxx u0 com.xyz.something.beta/xyz.something.abc.XYZService}

Now select your service and run:

adb shell am stopservice <service_name> 

For example:

adb shell am stopservice com.xyz.something.beta/xyz.something.abc.XYZService

similarly, to start service:

adb shell am startservice <service_name>

To access service, your service(in AndroidManifest.xml) should set exported="true"

<!-- Service declared in manifest -->
<service
    android:name=".YourServiceName"
    android:exported="true"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="com.your.package.name.YourServiceName"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</service>

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_

The best practice is definitely to avoid loops or recursions in Matlab.

Between sum(A(:)) and sum(sum(A)). In my experience, arrays in Matlab seems to be stored in a continuous block in memory as stacked column vectors. So the shape of A does not quite matter in sum(). (One can test reshape() and check if reshaping is fast in Matlab. If it is, then we have a reason to believe that the shape of an array is not directly related to the way the data is stored and manipulated.)

As such, there is no reason sum(sum(A)) should be faster. It would be slower if Matlab actually creates a row vector recording the sum of each column of A first and then sum over the columns. But I think sum(sum(A)) is very wide-spread amongst users. It is likely that they hard-code sum(sum(A)) to be a single loop, the same to sum(A(:)).

Below I offer some testing results. In each test, A=rand(size) and size is specified in the displayed texts.

In my experience, both timers are only meaningful up to .1s. So if you have similar experience with Matlab timers, none of the tests can discern sum(A(:)) and sum(sum(A)).

They seem equivalent. Either one is good. But sum(sum(A)) requires that you know the dimension of your array is 2.

For Jquery chosen if you send the attribute to function and need to update-select option

$('#yourElement option[value="'+yourValue+'"]').attr('selected', 'selected');
$('#editLocationCity').chosen().change();
$('#editLocationCity').trigger('liszt:updated');

If you want to access a property from inside a class you should:

private $classNumber = 8;

use the following

It will return a true or false

theObject instanceof Object

I know this is an old post. But here is how I have done it:

    public Form1(string myFile)
    {
        InitializeComponent();
        this.Show();
        if (myFile != null)
        {
            OpenFile(myFile);
        }
    }

    private void OpenFile(string myFile = null)
    {
            MessageBox.Show(myFile);
    }

The following worked for me:

var form_enabled = true;
$().ready(function(){
       // allow the user to submit the form only once each time the page loads
       $('#form_id').on('submit', function(){
               if (form_enabled) {
                       form_enabled = false;
                       return true;
               }

               return false;
        });
});

This cancels the submit event if the user tries to submit the form multiple times (by clicking a submit button, pressing Enter, etc.)

Using Apache Commons IOUtils you can do this nicely via

List<String> lines = IOUtils.readLines(new StringReader(string));

It's not doing anything clever, but it's nice and compact. It'll handle streams as well, and you can get a LineIterator too if you prefer.

This is how we can do it with the new useState hook. Method - Pass the state changer function as a props to the child component and do whatever you want to do with the function

import React, {useState} from 'react';

const ParentComponent = () => {
  const[state, setState]=useState('');
  
  return(
    <ChildConmponent stateChanger={setState} />
  )
}


const ChildConmponent = ({stateChanger, ...rest}) => {
  return(
    <button onClick={() => stateChanger('New data')}></button>
  )
}

None of the existing answers worked for me, but this approach did.

The problem

I was seeing lots of cells say #REF!. These are cells in a sheet that I copied from another Google Sheet doc using "Copy to > Existing Worksheet". If I press Enter in any cell, it recalculates correctly, But I don't want to do that for millions of cells.

My answer

I ran this recalcSheet() script. It takes almost 0.5 seconds per cell, which is very slow but is faster than manually fixing each cell.

function recalcSheet(){  
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet()
  var sheet = spreadsheet.getSheetByName("put_your_sheet_name_here");  // https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#getsheetbynamename
  // var range = sheet.getSelection().getActiveRange();
  // var range = sheet.getRange('A6:D6');
  var range = sheet.getDataRange();  
  recalcRange(range, spreadsheet);
}

function recalcRange(range, spreadsheet){
  // following structure of https://stackoverflow.com/a/52123839/470749
  Logger.log('Range: ' + range.getA1Notation());
  var numRows = range.getNumRows();
  var numCols = range.getNumColumns();
  var startRow = range.getRow();
  var startCol = range.getColumn();
  Logger.log('row: ' + startRow);
  Logger.log('col: ' + startCol);
  Logger.log('numRows: ' + numRows);
  Logger.log('numCols: ' + numCols);

  for (var r = 1; r <= numRows; r+=1) {
    for (var c = 1; c <= numCols; c+=1) {
      var originalFormula = range.getCell(r, c).getFormula(); // https://developers.google.com/apps-script/reference/spreadsheet/range#getFormula()
      Logger.log(`r,c ${r}, ${c}; originalFormula: ${originalFormula}`);
      if(originalFormula){
        range.getCell(r, c).setFormula('');
        //SpreadsheetApp.flush(); // https://webapps.stackexchange.com/a/35970/27487
        range.getCell(r, c).setFormula(originalFormula);
      }
    }
  }
  spreadsheet.toast('Each cell in the range has been recalculated.', "Finished!"); // https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#toast(String)
}

I have found an elegant solution that would cover most of your bases. I wrote about it initially here and answered another similar StackOverflow question here which references it.

FYI this solution also includes hardcoded fallback tags in case Javascript isn't picked up by the crawler. I haven't explicitly outlined it, but it is worth mentioning that you should be activating HTML5 mode for proper URL support.

Also note: these aren't the complete files, just the important parts of those that are relevant. If you need help writing the boilerplate for directives, services, etc. that can be found elsewhere. Anyway, here goes...

app.js

This is where you provide the custom metadata for each of your routes (title, description, etc.)

$routeProvider
   .when('/', {
       templateUrl: 'views/homepage.html',
       controller: 'HomepageCtrl',
       metadata: {
           title: 'The Base Page Title',
           description: 'The Base Page Description' }
   })
   .when('/about', {
       templateUrl: 'views/about.html',
       controller: 'AboutCtrl',
       metadata: {
           title: 'The About Page Title',
           description: 'The About Page Description' }
   })

metadata-service.js (service)

Sets the custom metadata options or use defaults as fallbacks.

var self = this;

// Set custom options or use provided fallback (default) options
self.loadMetadata = function(metadata) {
  self.title = document.title = metadata.title || 'Fallback Title';
  self.description = metadata.description || 'Fallback Description';
  self.url = metadata.url || $location.absUrl();
  self.image = metadata.image || 'fallbackimage.jpg';
  self.ogpType = metadata.ogpType || 'website';
  self.twitterCard = metadata.twitterCard || 'summary_large_image';
  self.twitterSite = metadata.twitterSite || '@fallback_handle';
};

// Route change handler, sets the route's defined metadata
$rootScope.$on('$routeChangeSuccess', function (event, newRoute) {
  self.loadMetadata(newRoute.metadata);
});

metaproperty.js (directive)

Packages the metadata service results for the view.

return {
  restrict: 'A',
  scope: {
    metaproperty: '@'
  },
  link: function postLink(scope, element, attrs) {
    scope.default = element.attr('content');
    scope.metadata = metadataService;

    // Watch for metadata changes and set content
    scope.$watch('metadata', function (newVal, oldVal) {
      setContent(newVal);
    }, true);

    // Set the content attribute with new metadataService value or back to the default
    function setContent(metadata) {
      var content = metadata[scope.metaproperty] || scope.default;
      element.attr('content', content);
    }

    setContent(scope.metadata);
  }
};

index.html

Complete with the hardcoded fallback tags mentioned earlier, for crawlers that can't pick up any Javascript.

<head>
  <title>Fallback Title</title>
  <meta name="description" metaproperty="description" content="Fallback Description">

  <!-- Open Graph Protocol Tags -->
  <meta property="og:url" content="fallbackurl.com" metaproperty="url">
  <meta property="og:title" content="Fallback Title" metaproperty="title">
  <meta property="og:description" content="Fallback Description" metaproperty="description">
  <meta property="og:type" content="website" metaproperty="ogpType">
  <meta property="og:image" content="fallbackimage.jpg" metaproperty="image">

  <!-- Twitter Card Tags -->
  <meta name="twitter:card" content="summary_large_image" metaproperty="twitterCard">
  <meta name="twitter:title" content="Fallback Title" metaproperty="title">
  <meta name="twitter:description" content="Fallback Description" metaproperty="description">
  <meta name="twitter:site" content="@fallback_handle" metaproperty="twitterSite">
  <meta name="twitter:image:src" content="fallbackimage.jpg" metaproperty="image">
</head>

This should help dramatically with most search engine use cases. If you want fully dynamic rendering for social network crawlers (which are iffy on Javascript support), you'll still have to use one of the pre-rendering services mentioned in some of the other answers.

Hope this helps!

I have just used dompdf and the code was a little different but it worked.

Here it is:

require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);

$html =
      '<html><body>'.
      '<p>Put your html here, or generate it with your favourite '.
      'templating system.</p>'.
      '</body></html>';

    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $output = $dompdf->output();
    file_put_contents('Brochure.pdf', $output);

Only difference here is that all of the files in the include directory are included.

Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.

In a different thread Justin suggests that the fastest way is to use strtok()

 $url = strtok($url, '?');

See his full answer with speed tests as well here: https://stackoverflow.com/a/1251650/452515

Run: npm link typescript if you installed globally

But if you have not installed typescript try this command: npm install typescript

You can use the :nth-child selector for that

li:nth-child(3n) {
 /* your rules here */
}

You can try this:

select * FROM table where (concat(first_name, ' ', last_name)) = $search_term;

I have had the same problem, but think I've got it under control now.

Are you using eclipse or command line or ??

When I use the command line, I think I did "seam clean" or "seam undeploy" or maybe even "seam restart" followed by "seam explode". I probably tried all of these at one time or another never bothering to look up what each one does.

The idea is to remove the deployed war file from TWO places

1. $JBOSS_HOME/server/default/deploy
2. $PROJECT_HOME/exploded_archives

I'm pretty sure "seam undeploy" removes the 1st and "seam clean" removes the 2nd.

When I use eclipse (I use the free one), I first turn off "Project/Build Automatically" Then when I am ready to deploy I do either Project/Build Project or Project/Build All depending on what I've changed. When I change xhtml, Build Project is sufficient. When I change java source Build All works. It's possible these do the same things and the difference is in my imagination, but some combination of this stuff will work for you.

You have to watch the output though. Occasionally the app does not get cleaned or undeployed. This would result in not seeing your change. Sometimes I shut down the server first and then rebuild/clean/deploy the project.

Hope this helps.

Install the ASP.NET AJAX Control Toolkit

1. Download the ZIP file AjaxControlToolkit-Framework3.5SP1-DllOnly.zip from the ASP.NET AJAX Control Toolkit Releases page of the CodePlex web site.

2. Copy the contents of this zip file directly into the bin directory of your web site.

Update web.config

3. Put this in your web.config under the <controls> section:

   <?xml version="1.0"?>
   <configuration>
       ...
       <system.web>
           ...
           <pages>
               ...
               <controls>
                   ...
                   <add tagPrefix="ajaxtoolkit"
                       namespace="AjaxControlToolkit"
                       assembly="AjaxControlToolKit"/>
               </controls>
           </pages>
           ...
       </system.web>
       ...
   </configuration>
   

Setup Visual Studio

4. Right-click on the Toolbox and select "Add Tab", and add a tab called "AJAX Control Toolkit"

5. Inside that tab, right-click on the Toolbox and select "Choose Items..."

6. When the "Choose Toolbox Items" dialog appears, click the "Browse..." button. Navigate to your project's "bin" folder. Inside that folder, select "AjaxControlToolkit.dll" and click OK. Click OK again to close the Choose Items Dialog.

You can now use the controls in your web sites!

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

To complement my own answer mentioned by TSamper,

• a rebase is quite often a good idea to do before a merge, because the idea is that you integrate in your branch Y the work of the branch B upon which you will merge.
  But again, before merging, you resolve any conflict in your branch (i.e.: "rebase", as in "replay my work in my branch starting from a recent point from the branch B).
  If done correctly, the subsequent merge from your branch to branch B can be fast-forward.

• a merge directly impacts the destination branch B, which means the merges better be trivial, otherwise that branch B can be long to get back to a stable state (time for you solve all the conflicts)

the point of merging after a rebase?

In the case that I describe, I rebase B onto my branch, just to have the opportunity to replay my work from a more recent point from B, but while staying into my branch.
In this case, a merge is still needed to bring my "replayed" work onto B.

The other scenario (described in Git Ready for instance), is to bring your work directly in B through a rebase (which does conserve all your nice commits, or even give you the opportunity to re-order them through an interactive rebase).
In that case (where you rebase while being in the B branch), you are right: no further merge is needed:

A Git tree at default when we have not merged nor rebased

we get by rebasing:

That second scenario is all about: how do I get new-feature back into master.

My point, by describing the first rebase scenario, is to remind everyone that a rebase can also be used as a preliminary step to that (that being "get new-feature back into master").
You can use rebase to first bring master "in" the new-feature branch: the rebase will replay new-feature commits from the HEAD master, but still in the new-feature branch, effectively moving your branch starting point from an old master commit to HEAD-master.
That allows you to resolve any conflicts in your branch (meaning, in isolation, while allowing master to continue to evolve in parallel if your conflict resolution stage takes too long).
Then you can switch to master and merge new-feature (or rebase new-feature onto master if you want to preserve commits done in your new-feature branch).

So:

• "rebase vs. merge" can be viewed as two ways to import a work on, say, master.
• But "rebase then merge" can be a valid workflow to first resolve conflict in isolation, then bring back your work.

To get min/max value in array, you can use:

var _array = [1,3,2];
Math.max.apply(Math,_array); // 3
Math.min.apply(Math,_array); // 1

Use DateTime.ToString with the specified format MM.dd.yyyy:

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

Here, MM means the month from 01 to 12, dd means the day from 01 to 31 and yyyy means the year as a four-digit number.

What about dir() and vars() now?

Seems doing exactly what is being asked super simply…

Must be called from within the function scope.

But be wary that it will return all local variables so be sure to do it at the very beginning of the function if needed.

Also note that, as pointed out in the comments, this doesn't allow it to be done from outside the scope. So not exactly OP's scenario but still matches the question title. Hence my answer.

The thing I use is this:

In your template an alert area

<div id="alert-area"></div>

Then an jQuery function for showing an alert

function newAlert (type, message) {
    $("#alert-area").append($("<div class='alert-message " + type + " fade in' data-alert><p> " + message + " </p></div>"));
    $(".alert-message").delay(2000).fadeOut("slow", function () { $(this).remove(); });
}
newAlert('success', 'Oh yeah!');

Windows MySQL v5 throws an error but Linux and other versions only raise a warning. This needs to be fixed. WTF?

Also see an attempt to fix this as bug #19498 in the MySQL Bugtracker:

Bryce Nesbitt on April 4 2008 4:36pm:
On MS Windows the "no DEFAULT" rule is an error, while on other platforms it is often a warning. While not a bug, it's possible to get trapped by this if you write code on a lenient platform, and later run it on a strict platform:

Personally, I do view this as a bug. Searching for "BLOB/TEXT column can't have a default value" returns about 2,940 results on Google. Most of them are reports of incompatibilities when trying to install DB scripts that worked on one system but not others.

I am running into the same problem now on a webapp I'm modifying for one of my clients, originally deployed on Linux MySQL v5.0.83-log. I'm running Windows MySQL v5.1.41. Even trying to use the latest version of phpMyAdmin to extract the database, it doesn't report a default for the text column in question. Yet, when I try running an insert on Windows (that works fine on the Linux deployment) I receive an error of no default on ABC column. I try to recreate the table locally with the obvious default (based on a select of unique values for that column) and end up receiving the oh-so-useful BLOB/TEXT column can't have a default value.

Again, not maintaining basic compatability across platforms is unacceptable and is a bug.

How to disable strict mode in MySQL 5 (Windows):

• Edit /my.ini and look for line

  sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
  

• Replace it with

  sql_mode='MYSQL40'
  

• Restart the MySQL service (assuming that it is mysql5)

  net stop mysql5
  net start mysql5
  

If you have root/admin access you might be able to execute

mysql_query("SET @@global.sql_mode='MYSQL40'");

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

I use SwitchToThisWindow to bring the application to the forefront as in this example:

static class Program
{
    [DllImport("User32.dll", SetLastError = true)]
    static extern void SwitchToThisWindow(IntPtr hWnd, bool fAltTab);



    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        bool createdNew;
        int iP;
        Process currentProcess = Process.GetCurrentProcess();
        Mutex m = new Mutex(true, "XYZ", out createdNew);
        if (!createdNew)
        {
            // app is already running...
            Process[] proc = Process.GetProcessesByName("XYZ");

            // switch to other process
            for (iP = 0; iP < proc.Length; iP++)
            {
                if (proc[iP].Id != currentProcess.Id)
                    SwitchToThisWindow(proc[0].MainWindowHandle, true);
            }

            return;
        }

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new form());
        GC.KeepAlive(m);

    }

In @Patrick McMahon's response, the second comment here ( $first_condition is false and $second_condition is true ) is not entirely accurate:

<?php if($first_condition): ?>
  /*$first_condition is true*/
  <div class="first-condition-true">First Condition is true</div>
<?php elseif($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
  <div class="second-condition-true">Second Condition is true</div>
<?php else: ?>
  /*$first_condition and $second_condition are false*/
  <div class="first-and-second-condition-false">Conditions are false</div>
<?php endif; ?>

Elseif fires whether $first_condition is true or false, as do additional elseif statements, if there are multiple.

I am no PHP expert, so I don't know whether that's the correct way to say IF this OR that ELSE that or if there is another/better way to code it in PHP, but this would be an important distinction to those looking for OR conditions versus ELSE conditions.

When you use a string literal the string can be interned, but when you use new String("...") you get a new string object.

In this example both string literals refer the same object:

String a = "abc"; 
String b = "abc";
System.out.println(a == b);  // true

Here, 2 different objects are created and they have different references:

String c = new String("abc");
String d = new String("abc");
System.out.println(c == d);  // false

In general, you should use the string literal notation when possible. It is easier to read and it gives the compiler a chance to optimize your code.

Java with stacks.

public class StackPalindrome {
    public boolean isPalindrome(String s) throws OverFlowException,EmptyStackException{
        boolean isPal=false;
        String pal="";
        char letter;

If we follow the activity template created by Android Studios, it's the AppBarLayout that needs to have an android theme of AppBarOverlay, which you should define in the your styles.xml. That should give you your white color toobar/actionbar color text.

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">  ...

In styles.xml, make sure the following exists:

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

from tkinter import *

window = tk()
window.geometry("300x300")

def close_window (): 

    window.destroy()

button = Button ( text = "Good-bye", command = close_window)
button.pack()

window.mainloop()

for a quick search in VIM, you could use at Vim Control prompt: /This is.*\_.*sentence

if ( 100 < 500 ) {
   //any action
}
else if ( 100 > 500 ){
   //any another action
}

Easy, use space

Should be AND instead of OR

select *
from MyTable
where CAST(Created as time) >= '23:00:00' 
   AND CAST(Created as time) < '07:00:00'

I think it's best to explicitly state where the form posts. If you want to be totally safe, enter the same URL the form is on in the action attribute if you want it to submit back to itself. Although mainstream browsers evaluate "" to the same page, you can't guarantee that non-mainstream browsers will.

And of course, the entire URL including GET data like Juddling points out.

If you'd like to use base graphics, you may have a look at this. An extract:

You can correct this with the res= argument to png, which specifies the number of pixels per inch. The smaller this number, the larger the plot area in inches, and the smaller the text relative to the graph itself.

In the newer apache poi versions:

XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop(BorderStyle.MEDIUM);
style.setBorderBottom(BorderStyle.MEDIUM);
style.setBorderLeft(BorderStyle.MEDIUM);
style.setBorderRight(BorderStyle.MEDIUM);

Try something like this...

<div id="wrapper" style="width:100%; text-align:center">
<img id="yourimage"/>
</div>

WARNING! THIS WILL DELETE THE ENTIRE GIT HISTORY FOR YOUR SUBMODULE. ONLY DO THIS IF YOU CREATED THE SUBMODULE BY ACCIDENT. CERTAINLY NOT WHAT YOU WANT TO DO IN MOST CASES.

In my situation, there was a sub-directory which had a .git directory.

What I do is simply remove that .git directory from my sub-directory.

If you use Width="*" the column will fill to expand the available space.

If you want all columns to divide the grid equally apply this to all columns. If you just want one to fill the remaining space just apply it to that column with the rest being "Auto" or a specific width.

You can also use Width="0.25*" (for example) if you want the column to take up 1/4 of the available width.

A simple solution for selecting 5 random files while avoiding to parse ls. It also works with files containing spaces, newlines and other special characters:

shuf -ezn 5 * | xargs -0 -n1 echo

Replace echo with the command you want to execute for your files.

It uses commas as separators. So you can either set sep="," or just use read.csv:

x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593      9

The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):

State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582

And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table with the default quote argument (but not read.csv):

01,089,24,033,MD,Prince George's County,13,30,1040

You can add the onclick for JavaScript into the div.

<div onclick="location.href='newurl.html';">&nbsp;</div>

EDIT: for new window

<div onclick="window.open('newurl.html','mywindow');" style="cursor: pointer;">&nbsp;</div>

To display a value nicely, you can use the pprint module. The easiest way to dump all variables with it is to do

from pprint import pprint

pprint(globals())
pprint(locals())

If you are running in CGI, a useful debugging feature is the cgitb module, which displays the value of local variables as part of the traceback.

based on S.Lott's top voted answer (Sep 25 '08 at 21:43), but fixed for small files.

def tail(the_file, lines_2find=20):

    return line_list[-lines_2find:]

    #we read at least 21 line breaks from the bottom, block by block for speed
    #21 to ensure we don't get a half line

Hope this is useful.

Your Mac does indeed run a BASH shell, but this is more a question of which implementation of sed you are dealing with. On a Mac sed comes from BSD and is subtly different from the sed you might find on a typical Linux box. I suggest you man sed.

Here's a more complete and flexible example that doesn't omit necessary includes to generate compilation errors:

#include <iostream>
#include <unordered_map>

class Hashtable {
    std::unordered_map<const void *, const void *> htmap;

public:
    void put(const void *key, const void *value) {
            htmap[key] = value;
    }

    const void *get(const void *key) {
            return htmap[key];
    }

};

int main() {
    Hashtable ht;
    ht.put("Bob", "Dylan");
    int one = 1;
    ht.put("one", &one);
    std::cout << (char *)ht.get("Bob") << "; " << *(int *)ht.get("one");
}

Still not particularly useful for keys, unless they are predefined as pointers, because a matching value won't do! (However, since I normally use strings for keys, substituting "string" for "const void *" in the declaration of the key should resolve this problem.)

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.

I had to disable selinux to make this work. Note. The system needs to be rebooted for selinux to take effect.

android:layout_gravity="center"

or

android:gravity="center"

both works for me.

This is very simple you need to keep different names of every radio input group.

      <input type="radio" name="price">Thousand<br>_x000D_
      <input type="radio" name="price">Lakh<br>_x000D_
      <input type="radio" name="price">Crore_x000D_
      _x000D_
      </br><hr>_x000D_
_x000D_
      <input type="radio" name="gender">Male<br>_x000D_
      <input type="radio" name="gender">Female<br>_x000D_
      <input type="radio" name="gender">Other

I had this same notice appear after making some changes. It turned out to be because I had changed between a single $http request to multiple requests using angularjs $q service.

I hadn't wrapped them in an array. e.g.

$q.all(request1, request2).then(...) 

rather than

$q.all([request1, request2]).then(...)

I hope this might save somebody some time.

You could build your form using FormBuilder as it let you more flexible way to configure form.

export class MyComp {
  form: ControlGroup;

  constructor(@Inject()fb: FormBuilder) {  
    this.form = fb.group({  
      foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]  
    });  
  }

Then in your template :

<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div> 

You can also customize ng-invalid CSS class.

As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.

export class MyValidators {
  static regex(pattern: string): Function {
    return (control: Control): {[key: string]: any} => {
      return control.value.match(pattern) ? null : {pattern: true};
    };
  }
}

Hope that it help you.

Yes. Bootstrap uses CSS transitions so it can be done easily without any Javascript. Just use CSS3. Please take a look at

carousel.carousel-fade

in the CSS of the following examples:

• http://jsfiddle.net/seemly/ww67B/123/
• http://bootply.com/86170
• http://codepen.io/Rowno/pen/Afykb

R defines a ~ (tilde) operator for use in formulas. Formulas have all sorts of uses, but perhaps the most common is for regression:

library(datasets)
lm( myFormula, data=iris)

help("~") or help("formula") will teach you more.

@Spacedman has covered the basics. Let's discuss how it works.

First, being an operator, note that it is essentially a shortcut to a function (with two arguments):

> `~`(lhs,rhs)
lhs ~ rhs
> lhs ~ rhs
lhs ~ rhs

That can be helpful to know for use in e.g. apply family commands.

Second, you can manipulate the formula as text:

oldform <- as.character(myFormula) # Get components
myFormula <- as.formula( paste( oldform[2], "Sepal.Length", sep="~" ) )

Third, you can manipulate it as a list:

myFormula[[2]]
myFormula[[3]]

Finally, there are some helpful tricks with formulae (see help("formula") for more):

myFormula <- Species ~ . 

For example, the version above is the same as the original version, since the dot means "all variables not yet used." This looks at the data.frame you use in your eventual model call, sees which variables exist in the data.frame but aren't explicitly mentioned in your formula, and replaces the dot with those missing variables.

You can remove an item by one of its properties without using any 3rd party libs like this:

var removeIndex = array.map(item => item.id)
                       .indexOf("abc");

~removeIndex && array.splice(removeIndex, 1);

Manually creating a folder named 'npm' in the displayed path fixed the problem.

More information can be found on Troubleshooting page

https://github.com/jakubgorny47/baku-code/tree/master/c_vector

Here's my implementation. It's basicaly a struct containing pointer to the data, size (in elements), overall allocated space and a size of the type that's being stored in vector to allow use of void pointer.

You can get more information if you run the following command:

netstat -aon | find /i "listening" |find "port"

using the 'Find' command allows you to filter the results. find /i "listening" will display only ports that are 'Listening'. Note, you need the /i to ignore case, otherwise you would type find "LISTENING". | find "port" will limit the results to only those containing the specific port number. Note, on this it will also filter in results that have the port number anywhere in the response string.

Let Spring 3 injection take care of this.

Thanks to tsunade21 the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView anyMethodNameGoesHere(Principal principal) {
        final String loggedInUserName = principal.getName();

 }

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

For some reason the solution mentioned for httpClient above didn't worked for me. At the end I was able to make it work by correctly overriding the method when implementing the custom SSLSocketFactory class.

@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) 
                              throws IOException, UnknownHostException 
    {
    return sslFactory.createSocket(socket, host, port, autoClose);
}

@Override
public Socket createSocket() throws IOException {
    return sslFactory.createSocket();
}

This is how it worked perfectly for me. You can see the full custom class and implementing on the following thread: http://blog.syedgakbar.com/2012/07/21/android-https-and-not-trusted-server-certificate-error/

Here's yet another way to do it, one that reproduces the slight indentation of UITextField's placeholder:

Drag a UITextField right under the UITextView so that their top left corners are aligned. Add your placeholder text to the text field.

In viewDidLoad, add:

[tView setDelegate:self];
tView.contentInset = UIEdgeInsetsMake(-8,-8,0,0);
tView.backgroundColor = [UIColor clearColor];

Then add:

- (void)textViewDidChange:(UITextView *)textView {
    if (textView.text.length == 0) {
        textView.backgroundColor = [UIColor clearColor];            
    } else {
        textView.backgroundColor = [UIColor whiteColor];
    }
}

For me reinstalling and then upgrading the pip worked.

1. Reinstall pip by using below command or following link How do I install pip on macOS or OS X?

   curl https://bootstrap.pypa.io/get-pip.py -o - | python

2. Upgrade pip after it's installed

   pip install -U pip

Using JSTL:

<c:set var="message" value='${requestScope["Error_Message"]}' />

Here var sets the variable name and request.getAttribute is equal to requestScope. But it's not essential. ${Error_Message} will give you the same outcome. It'll search every scope. If you want to do some operation with content you take from Error_Message you have to do it using message. like below one.

<c:out value="${message}"/>

For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors

Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)

instead of using the redirection operator > to create my file

Note: I didn't put any xml parameters in my beans tag and it works

Probably because of optimizations. Excel 2007 can have a maximum of 16 384 columns and 1 048 576 rows. Strange numbers?

14 bits = 16 384, 20 bits = 1 048 576

14 + 20 = 34 bits = more than one 32 bit register can hold.

But they also need to store the format of the cell (text, number etc) and formatting (colors, borders etc). Assuming they use two 32-bit words (64 bit) they use 34 bits for the cell number and have 30 bits for other things.

Why is that important? In memory they don't need to allocate all the memory needed for the whole spreadsheet but only the memory necessary for your data, and every data is tagged with in what cell it is supposed to be in.

Update 2016:

Found a link to Microsoft's specification for Excel 2013 & 2016

Correct way to do in Swift 4, If your frame as screen size is correct then put anywhere otherwise, important to write this in viewDidLayoutSubviews because we can get actual frame in viewDidLayoutSubviews

   override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        UIGraphicsBeginImageContext(view.frame.size)
        UIImage(named: "myImage")?.draw(in: self.view.bounds)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        view.backgroundColor = UIColor.init(patternImage: image!)
    }

Well, first, you need to actually define a function before you can run it (and it doesn't need to be called main). For instance:

class Example(object):
    def run(self):
        print "Hello, world!"

if __name__ == '__main__':
    Example().run()

You don't need to use a class, though - if all you want to do is run some code, just put it inside a function and call the function, or just put it in the if block:

def main():
    print "Hello, world!"

if __name__ == '__main__':
    main()

or

if __name__ == '__main__':
    print "Hello, world!"

Interesting. On my 64-bit (i7 Ubuntu) box:

>>> print type(0x7FFFFFFF)
<type 'int'>
>>> print type(0x7FFFFFFF+1)
<type 'int'>

Guess it steps up to 64 bit ints on a larger machine.

Negatives are your friend here:

SELECT Col1
FROM TABLE
WHERE Col1 like '%[^a-Z0-9]%'

Which says that you want any rows where Col1 consists of any number of characters, then one character not in the set a-Z0-9, and then any number of characters.

If you have a case sensitive collation, it's important that you use a range that includes both upper and lower case A, a, Z and z, which is what I've given (originally I had it the wrong way around. a comes before A. Z comes after z)

Or, to put it another way, you could have written your original WHERE as:

Col1 LIKE '[!@#$%]'

But, as you observed, you'd need to know all of the characters to include in the [].

I think there is an another way to understand it.

For a np.array,if we want eliminate columns we use axis = 1; if we want eliminate rows, we use axis = 0.

np.mean(np.array(np.ones(shape=(3,5,10))),axis = 0).shape # (5,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = 1).shape # (3,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = (0,1)).shape # (10,)

For pandas object, axis = 0 stands for row-wise operation and axis = 1 stands for column-wise operation. This is different from numpy by definition, we can check definitions from numpy.doc and pandas.doc

This code will delete all characters that you enter from string

#include <stdio.h>
#include <string.h>

#define SIZE 1000

char *erase_c(char *p, int ch)
{
    char *ptr;

    while (ptr = strchr(p, ch))
        strcpy(ptr, ptr + 1);

    return p;
}

int main()
{
    char str[SIZE];
    int ch;

    printf("Enter a string\n");
    gets(str);
    printf("Enter the character to delete\n");
    ch = getchar();

    erase_c(str, ch);

    puts(str);

    return 0;
}

input

a man, a plan, a canal Panama

output

 A mn,  pln,  cnl, Pnm!

A bit old question but I found myself needing this also and that the suggestions above were inaduquate - and as such - developed a thin wrapper myself: https://github.com/hofmeister/MatchIt

I just discovered that the Mock library provides an assertRaisesWithMessage() method (in its unittest.TestCase subclass), which will check not only that the expected exception is raised, but also that it is raised with the expected message:

from testcase import TestCase

import mymod

class MyTestCase(TestCase):
    def test1(self):
        self.assertRaisesWithMessage(SomeCoolException,
                                     'expected message',
                                     mymod.myfunc)

Here's a macro based on the one in the link posted by Wael, but improved in the following areas:

• slightly shorter
• slightly faster
• comments :)
• behaves for lines starting with "///"
• can be undone with a single undo

Imports System
Imports EnvDTE
Imports EnvDTE80

Public Module Module1

    Sub DuplicateLine()
        Dim sel As TextSelection = DTE.ActiveDocument.Selection
        sel.StartOfLine(0) '' move to start
        sel.EndOfLine(True) '' select to end
        Dim line As String = sel.Text
        sel.EndOfLine(False) '' move to end
        sel.Insert(ControlChars.NewLine + line, vsInsertFlags.vsInsertFlagsCollapseToEnd)
    End Sub

End Module

Instead of:

input:not(disabled)not:[type="submit"]:focus {}

Use:

input:not([disabled]):not([type="submit"]):focus {}

disabled is an attribute so it needs the brackets, and you seem to have mixed up/missing colons and parentheses on the :not() selector.

Demo: http://jsfiddle.net/HSKPx/

One thing to note: I may be wrong, but I don't think disabled inputs can normally receive focus, so that part may be redundant.

Alternatively, use :enabled

input:enabled:not([type="submit"]):focus { /* styles here */ }

Again, I can't think of a case where disabled input can receive focus, so it seems unnecessary.

Someone has already made a benchmark: jQuery document.createElement equivalent?

$(document.createElement('div')) is the big winner.

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

How to remove a tagged image

1. docker rmi the tag first

2. docker rmi the image.

   # that can be done in one docker rmi call e.g.: # docker rmi <repo:tag> <imageid>

(this works Nov 2016, Docker version 1.12.2)

e.g.

$ docker images

Set that particular column's Visible property = false

dataGridView[ColumnName or Index].Visible = false;

Edit sorry missed the Columns Property dataGridView.Columns[ColumnName or Index].Visible = false;

Using standard java libs, I suggest looking at the HttpUrlConnection class http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html

It can handle most of what curl can do with setting up the connection. What you do with the stream is up to you.

If nobody has pulled your remote repo yet, you can change your branch HEAD and force push it to said remote repo:

git reset --hard HEAD^ 
git push -f 

(or, if you have direct access to the remote repo, you can change its HEAD reference even though it is a bare repo)

Note, as commented by alien-technology in the comments below, on Windows (CMD session), you would need ^^:

git reset --hard HEAD^^
git push -f 

Update since 2011:
Using git push --force-with-lease (that I present here, introduced in 2013 with Git 1.8.5) is safer.

See Schwern's answer for illustration.

What if somebody has already pulled the repo? What would I do then?

Then I would suggest something that doesn't rewrite the history:

• git revert locally your last commit (creating a new commit that reverses what the previous commit did)
• push the 'revert' generated by git revert.

I have seen this and answered on it before:

After further research I have discovered that inline-block is a whitespace dependent method and is dependent on the font setting. In this case 4px is rendered.

To avoid this you could run all your lis together in one line, or block the end tags and begin tags together like this:

<ul>
        <li>
            <div>first</div>
        </li><li>
            <div>first</div>
        </li><li>
            <div>first</div>
        </li><li>
            <div>first</div>
        </li>
</ul>

Example here.

As mentioned by other answers and comments, the best practice for solving this is to add font-size: 0; to the parent element:

ul {
    font-size: 0;
}

ul li {
    font-size: 14px;
    display: inline-block;
}

This is better for HTML readability (avoiding running the tags together etc). The spacing effect is because of the font's spacing setting, so you must reset it for the inlined elements and set it again for the content within.

This is Function which will convert most of the video formats to number of frames there are in the video. It works on Python3 with OpenCV 3+

It supports .mts and normal files like .mp4 and .avi. Tried and Tested on .mts files. Works like a Charm.

I couldn't see it as an answer here so I thought I would mention that I recieved this error using spring 4.2 when I accidentally removed the getter/setter for the class I was expecting to be returned as Json.
