doesn't

<?php get_the_category( $id ) ?>

do just that, inside the loop?

For outside:

<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

This is not possible in the requested way because there are numbers with two decimal places which can not be expressed exactly using IEEE floating point numbers (for example 1/10 = 0.1 can not be expressed as a Double or Float). The formatting should always happen as the last step before presenting the result to the user.

I guess you are asking because you want to deal with monetary values. There is no way to do this reliably with floating-point numbers, you shoud consider switching to fixed-point arithmetics. This probably means doing all calculations in "cents" instead of "dollars".

[ ] defines a character class. So every character you set there, will match. [012] will match 0 or 1 or 2 and [0-2] behaves the same.

What you want is groupings to define a or-statement. Use (s|season) for your issue.

Btw. you have to watch out. Metacharacters in normal regex (or inside a grouping) are different from character class. A character class is like a sub-language. [$A] will only match $ or A, nothing else. No escaping here for the dollar.

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

As of Fedora 17 it is possible to easily build (cross-compile) binaries for the win32 and win64 targets. This is realized using the mingw-w64 toolchain: http://mingw-w64.sf.net/. Using this toolchain allows you to build binaries for the following programming languages: C, C++, Objective-C, Objective-C++ and Fortran.

There is also EntityFunctions.TruncateTime or DbFunctions.TruncateTime in EF 6.0

nonatomic/atomic

• nonatomic is much faster than atomic
• always use nonatomic unless you have a very specific requirement for atomic, which should be rare (atomic doesn't guarantee thread safety - only stalls accessing the property when it's simultaneously being set by another thread)

strong/weak/assign

• use strong to retain objects - although the keyword retain is synonymous, it's best to use strong instead
• use weak if you only want a pointer to the object without retaining it - useful for avoid retain cycles (ie. delegates) - it will automatically nil out the pointer when the object is released
• use assign for primatives - exactly like weak except it doesn't nil out the object when released (set by default)

(Optional)

copy

• use it for creating a shallow copy of the object
• good practice to always set immutable properties to copy - because mutable versions can be passed into immutable properties, copy will ensure that you'll always be dealing with an immutable object
• if an immutable object is passed in, it will retain it - if a mutable object is passed in, it will copy it

readonly

• use it to disable setting of the property (prevents code from compiling if there's an infraction)
• you can change what's delivered by the getter by either changing the variable directly via its instance variable, or within the getter method itself

$array[9] = 'Apple';
$array[12] = 'Orange';
$array[5] = 'Peach';

$array = array_values($array);

through this function you can reset your array

$array[0] = 'Apple';
$array[1] = 'Orange';
$array[2] = 'Peach';

SELECT <...> 
FROM A.tableA JOIN B.tableB 

In my case, boolean values in my Python dict were the problem. JSON boolean values are in lowercase ("true", "false") whereas in Python they are in Uppercase ("True", "False"). Couldn't find this solution anywhere online but hope it helps.

The whole code in the document will be:

graph = {'A': ['B', 'C'],
             'B': ['C', 'D'],
             'C': ['D'],
             'D': ['C'],
             'E': ['F'],
             'F': ['C']}
def find_path(graph, start, end, path=[]):
        path = path + [start]
        if start == end:
            return path
        if start not in graph:
            return None
        for node in graph[start]:
            if node not in path:
                newpath = find_path(graph, node, end, path)
                if newpath: return newpath
        return None

After writing it, save the document and press F 5

After that, the code you will run in the Python IDLE shell will be:

find_path(graph, 'A','D')

The answer you should receive in IDLE is

['A', 'B', 'C', 'D'] 

Here all solutions are based on Class Component, but i guess most of the people who learned React recently (like me), at this time using functional Component. So here is the solution based on functional component.

Using useRef hooks of ReactJs and inputRef property of TextField.

    import React, { useRef, Component } from 'react'
    import { TextField, Button } from '@material-ui/core'
    import SendIcon from '@material-ui/icons/Send'

    export default function MultilineTextFields() {
    const valueRef = useRef('') //creating a refernce for TextField Component

    const sendValue = () => {
        return console.log(valueRef.current.value) //on clicking button accesing current value of TextField and outputing it to console 
    }

    return (
        <form noValidate autoComplete='off'>
        <div>
            <TextField
            id='outlined-textarea'
            label='Content'
            placeholder='Write your thoughts'
            multiline
            variant='outlined'
            rows={20}
            inputRef={valueRef}   //connecting inputRef property of TextField to the valueRef
            />
            <Button
            variant='contained'
            color='primary'
            size='small'
            endIcon={<SendIcon />}
            onClick={sendValue}
            >
            Send
            </Button>
        </div>
        </form>
    )
    }

In my case it was simply an error in the web.config.

I had:

<endpoint address="http://localhost/WebService/WebOnlineService.asmx" 

It should have been:

<endpoint address="http://localhost:10593/WebService/WebOnlineService.asmx"

The port number (:10593) was missing from the address.

Emails require tables in order to work properly.

Inky (by foundation for emails) is a templating language that converts simple HTML tags into the complex table HTML required for emails.

Example

<html>

<head></head>

<body>
  <table align="center" class="container">
    <tbody>
      <tr>
        <td>
          <table class="row">
            <tbody>
              <tr>
                <th class="small-12 large-12 columns first last">
                  <table>
                    <tbody>
                      <tr>
                        <th>Put content in me!</th>
                        <th class="expander"></th>
                      </tr>
                    </tbody>
                  </table>
                </th>
              </tr>
            </tbody>
          </table>&zwj;
        </td>
      </tr>
    </tbody>
  </table>
</body>

</html>

Will produce this:

The best way to do this given your setup is to define a constant describing the root path of your site. You can create a file config.php at the root of your application:

<?php

define('SITE_ROOT', dirname(__FILE__));

$file_path = SITE_ROOT . '/Texts/MyInfo.txt';

?>

Then include config.php in each entry point script and reference SITE_ROOT in your code rather than giving a relative path.

Here is an example that sets the image path dynamically (image located somewhere on disc rather than build as resource):

if (File.Exists(imagePath))
{
    // Create image element to set as icon on the menu element
    Image icon = new Image();
    BitmapImage bmImage = new BitmapImage();
    bmImage.BeginInit();
    bmImage.UriSource = new Uri(imagePath, UriKind.Absolute);
    bmImage.EndInit();
    icon.Source = bmImage;
    icon.MaxWidth = 25;
    item.Icon = icon;
}

Reflections on Icons...

First thought, you would think that the Icon property can only contain an image. But it can actually contain anything! I discovered this by accident when I programmatically tried to set the Image property directly to a string with the path to an image. The result was that it did not show the image, but the actual text of the path!

This leads to an alternative to not have to make an image for the icon, but use text with a symbol font instead to display a simple "icon". The following example uses the Wingdings font which contains a "floppydisk" symbol. This symbol is really the character <, which has special meaning in XAML, so we have to use the encoded version < instead. This works like a dream! The following shows a floppydisk symbol as an icon on the menu item:

<MenuItem Name="mnuFileSave" Header="Save" Command="ApplicationCommands.Save">
  <MenuItem.Icon>
    <Label VerticalAlignment="Center" HorizontalAlignment="Center" FontFamily="Wingdings">&lt;</Label>
  </MenuItem.Icon>
</MenuItem>

Ok so i found out the problem :)

ctrl+alt+delete to start task manager, once you get to task manager go to services. find MySQL and right click on it. Then click stop process. That worked for me and i hope it works for you :D

You can just construct a list from the range object:

my_list = list(range(1, 1001))

This is how you do it with generators in python2.x as well. Typically speaking, you probably don't need a list though since you can come by the value of my_list[i] more efficiently (i + 1), and if you just need to iterate over it, you can just fall back on range.

Also note that on python2.x, xrange is still indexable¹. This means that range on python3.x also has the same property²

^{1print xrange(30)[12] works for python2.x}

^{2The analogous statement to 1 in python3.x is print(range(30)[12]) and that works also.}

I had a similar problem with truncated tar files being produced by a cron job and redirecting standard out to a file fixed the issue.

From talking to a colleague, cron creates a pipe and limits the amount of output that can be sent to standard out. I fixed mine by removing -v from my tar command, making it much less verbose and keeping the error output in the same spot as the rest of my cron jobs. If you need the verbose tar output, you'll need to redirect to a file, though.

I used this

:top
cls
type G:\empty.txt
type I:\empty.txt
timeout /T 500
goto top

you need to make county_ID as index for the right frame:

frame_2.join ( frame_1.set_index( [ 'county_ID' ], verify_integrity=True ),
               on=[ 'countyid' ], how='left' )

for your information, in pandas left join breaks when the right frame has non unique values on the joining column. see this bug.

so you need to verify integrity before joining by , verify_integrity=True

With C#6.0 you also have a new way of formatting date when using string interpolation e.g.

$"{DateTime.Now:yyyy-MM-dd HH:mm:ss}"

Can't say its any better, but it is slightly cleaner if including the formatted DateTime in a longer string.

More about string interpolation.

FILE=test

while read CMD; do
    echo "$CMD"
done < "$FILE"

A redirection with < "$FILE" has a few advantages over cat "$FILE" | while .... It avoids a useless use of cat, saving an unnecessary child process. It also avoids a common pitfall where the loop runs in a subshell. In bash, commands in a | pipeline run in subshells, which means variable assignments are lost after the loop ends. Redirection with < doesn't have that problem, so you could use $CMD after the loop or modify other variables inside the loop. It also, again, avoids unnecessary child processes.

There are some additional improvements that could be made:

• Add IFS= so that read won't trim leading and trailing whitespace from each line.
• Add -r to read to prevent from backslashes from being interpreted as escape sequences.
• Lower case CMD and FILE. The bash convention is only environmental and internal shell variables are uppercase.
• Use printf in place of echo which is safer if $cmd is a string like -n, which echo would interpret as a flag.

file=test

while IFS= read -r cmd; do
    printf '%s\n' "$cmd"
done < "$file"

A Java ClassCastException is an Exception that can occur when you try to improperly convert a class from one type to another.

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class ClassCastExceptionExample {

  public ClassCastExceptionExample() {

    List list = new ArrayList();
    list.add("one");
    list.add("two");
    Iterator it = list.iterator();
    while (it.hasNext()) {
        // intentionally throw a ClassCastException by trying to cast a String to an
        // Integer (technically this is casting an Object to an Integer, where the Object 
        // is really a reference to a String:
        Integer i = (Integer)it.next();
    }
  }
 public static void main(String[] args) {
  new ClassCastExceptionExample();
 }
}

If you try to run this Java program you’ll see that it will throw the following ClassCastException:

Exception in thread "main" java.lang.ClassCastException: java.lang.String
at ClassCastExceptionExample  (ClassCastExceptionExample.java:15)
at ClassCastExceptionExample.main  (ClassCastExceptionExample.java:19)

The reason an exception is thrown here is that when I’m creating my list object, the object I store in the list is the String “one,” but then later when I try to get this object out I intentionally make a mistake by trying to cast it to an Integer. Because a String cannot be directly cast to an Integer — an Integer is not a type of String — a ClassCastException is thrown.

(solved my problem) File -> Project structures -> Modules -> Add (small plus sign) -> Import Module -> Add the path contains the files (e.g. src/mymodule) -> Create Module from existing sources -> Next -> next -> Finish. You should see a file with .iml in the directory where you cannot imoport; that should do the trick

SMS Push uses SMS as a carrier, WAP uses download via WAP.

Other Way is:

String[] parts = selectedFilePath.split("/");
    final String fileName = parts[parts.length-1];

You may need to handle javax.persistence.RollbackException

There is one common answer I haven't see here yet, which is the Window Function. It is an alternative to the correlated sub-query, if your DB supports it.

SELECT sensorID,timestamp,sensorField1,sensorField2 
FROM (
    SELECT sensorID,timestamp,sensorField1,sensorField2
        , ROW_NUMBER() OVER(
            PARTITION BY sensorID
            ORDER BY timestamp
        ) AS rn
    FROM sensorTable s1
WHERE rn = 1
ORDER BY sensorID, timestamp;

I acually use this more than correlated sub-queries. Feel free to bust me in the comments over effeciancy, I'm not too sure how it stacks up in that regard.

ls -ltrh /proc | grep YOUR-PID-HERE

For example, my Google Chrome's PID is 11583:

ls -l /proc | grep 11583
dr-xr-xr-x  7 adam       adam                     0 2011-04-20 16:34 11583

SOLVED
After banging my head on the wall for a couple days with this issue, it was looking like the problem had something to do with the content type negotiation between the client and server. I dug deeper into that using Fiddler to check the request details coming from the client app, here's a screenshot of the raw request as captured by fiddler:

What's obviously missing there is the Content-Type header, even though I was setting it as seen in the code sample in my original post. I thought it was strange that the Content-Type never came through even though I was setting it, so I had another look at my other (working) code calling a different Web API service, the only difference was that I happened to be setting the req.ContentType property prior to writing to the request body in that case. I made that change to this new code and that did it, the Content-Type was now showing up and I got the expected success response from the web service. The new code from my .NET client now looks like this:

req.Method = "POST"
req.ContentType = "application/json"
lstrPagingJSON = JsonSerializer(Of Paging)(lPaging)
bytData = Encoding.UTF8.GetBytes(lstrPagingJSON)
req.ContentLength = bytData.Length
reqStream = req.GetRequestStream()
reqStream.Write(bytData, 0, bytData.Length)
reqStream.Close()
'// Content-Type was being set here, causing the problem
'req.ContentType = "application/json"

That's all it was, the ContentType property just needed to be set prior to writing to the request body

I believe this behavior is because once content is written to the body it is streamed to the service endpoint being called, any other attributes pertaining to the request need to be set prior to that. Please correct me if I'm wrong or if this needs more detail.

Most of the cases like getting query string or form parameters are covered in answers above.

When working with raw data, like a raw JSON string in the body that you would like to give as an argument to json_decode(), the method Request::getContent() can be used.

$content = $request->getContent();

Additional useful informations on HTTP requests in Symfony can be found on the HttpFoundation package's documentation.

Both tools are meant to work with text and there are tasks both tools can be used for.

For me the rule to separate them is: Use sed to automate tasks you would do otherwise in a text editor manually. That's why it is called stream editor. (You can use the same commands to edit text in vim). Use awk if you want to analyze text, meaning counting fields, calculate totals, extract and reorganize structures etc.

Also you should not forget about grep. Use grep if you only want to search/extract something in a text (file)

I had the same probem a while ago, before starting using Symfony framework.

1. Just use a function __() which has arameters pageId (or objectId, objectTable described in #2), target language and an optional parameter of fallback (default) language. The default language could be set in some global config in order to have an easier way to change it later.

2. For storing the content in database i used following structure: (pageId, language, content, variables).

   • pageId would be a FK to your page you want to translate. if you have other objects, like news, galleries or whatever, just split it into 2 fields objectId, objectTable.

   • language - obviously it would store the ISO language string EN_en, LT_lt, EN_us etc.

   • content - the text you want to translate together with the wildcards for variable replacing. Example "Hello mr. %%name%%. Your account balance is %%balance%%."

   • variables - the json encoded variables. PHP provides functions to quickly parse these. Example "name: Laurynas, balance: 15.23".

   • you mentioned also slug field. you could freely add it to this table just to have a quick way to search for it.

3. Your database calls must be reduced to minimum with caching the translations. It must be stored in PHP array, because it is the fastest structure in PHP language. How you will make this caching is up to you. From my experience you should have a folder for each language supported and an array for each pageId. The cache should be rebuilt after you update the translation. ONLY the changed array should be regenerated.

4. i think i answered that in #2

5. your idea is perfectly logical. this one is pretty simple and i think will not make you any problems.

URLs should be translated using the stored slugs in the translation table.

Final words

it is always good to research the best practices, but do not reinvent the wheel. just take and use the components from well known frameworks and use them.

take a look at Symfony translation component. It could be a good code base for you.

You can have a static field to store this kind of state. Or put it to the resource Bundle and restore from there on onCreate(Bundle savedInstanceState). Just make sure you entirely understand Android app managed lifecycle (e.g. why login() gets called on keyboard orientation change).

I would use an <a></a> tag then set the href='path'. Afterwards, place an image in between the <a> elements so that I can have a visual to see it. If you wanted to, you could create a function that will change the href so that it won't just be the same link but be dynamic.

Give the <a> tag an id as well if you want to access it with javascript.

Starting with the HTML Version:

<a href="mp3/tupac_shakur-how-do-you-want-it.mp3" download id="mp3Anchor">
     <img src="some image that you want" alt="some description" width="100px" height="100px" />
</a>

Now with JavaScript:

*Create a small json file*;

const array = [
     "mp3/tupac_shakur-how-do-you-want-it.mp3",
     "mp3/spice_one-born-to-die.mp3",
     "mp3/captain_planet_theme_song.mp3",
     "mp3/tenchu-intro.mp3",
     "mp3/resident_evil_nemesis-intro-theme.mp3"
];

//load this function on window
window.addEventListener("load", downloadList);

//now create a function that will change the content of the href with every click
function downloadList() {
     var changeHref=document.getElementById("mp3Anchor");

     var j = -1;

     changeHref.addEventListener("click", ()=> {

           if(j < array.length-1) {
               j +=1;
               changeHref.href=""+array[j];
          }
           else {
               alert("No more content to download");
          }
}

For @atari2600, this is what the answer would look like using ToLookup in lambda syntax:

var x = listOfCustomObjects
    .GroupBy(o => o.PropertyName)
    .ToLookup(customObject => customObject);

Basically, it takes the IGrouping and materializes it for you into a dictionary of lists, with the values of PropertyName as the key.

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

BufferedImage in = ImageIO.read(img);

BufferedImage newImage = new BufferedImage(
    in.getWidth(), in.getHeight(), BufferedImage.TYPE_INT_ARGB);

Graphics2D g = newImage.createGraphics();
g.drawImage(in, 0, 0, null);
g.dispose();

System.out.println("I\nam\na\nboy");

System.out.println("I am a boy".replaceAll("\\s+","\n"));

System.out.println("I am a boy".replaceAll("\\s+",System.getProperty("line.separator"))); // portable way

In addition to what Salaryman said, take a look at the classes in PEAR, there are HTTP request classes there that you can use even if you do not have the cURL extension installed in your PHP distribution.

there are two columns in the a table ID and name where names are repeating with different IDs so for that you may use this query: . .

DELETE FROM dbo.tbl1
WHERE id NOT IN (
     Select MIN(Id) AS namecount FROM tbl1
     GROUP BY Name
)

This should fulfill your requirements.

I was able to correct the flaw by changing the file below:

C:\Windows\System32\inetsrv\config\applicationHost.config

<application path="/Bonobo.Git.Server" applicationPool="ASP.NET v4.0">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\Bonobo.Git.Server" />
</application>

For:

<application path="/">

</application>

I found myself requiring this functionality often enough that I packaged it into a library called std-pour. It should let you execute a command and view the output in real time. To install simply:

npm install std-pour

Then it's simple enough to execute a command and see the output in realtime:

const { pour } = require('std-pour');
pour('ping', ['8.8.8.8', '-c', '4']).then(code => console.log(`Error Code: ${code}`));

It's promised based so you can chain multiple commands. It's even function signature-compatible with child_process.spawn so it should be a drop in replacement anywhere you're using it.

private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

public static long GetCurrentUnixTimestampMillis()
{
    DateTime localDateTime, univDateTime;
    localDateTime = DateTime.Now;          
    univDateTime = localDateTime.ToUniversalTime();
    return (long)(univDateTime - UnixEpoch).TotalMilliseconds;
} 

I didn't have the same problem but similar. Below code solves your problem too, of course if you don't mind performance issue. Before implement that kind of solution to your system I recommend you to redesign your structure if you can. Sending variable structure response is over-engineering. I believe a response structure represents a contract between a request and resource and it should't be depend requests.(you can make un-wanted fields null, I do). In some cases we have to implement this design, if you believe you are in that cases here is the play link and code I use.

type User2 struct {
    ID       int    `groups:"id" json:"id,omitempty"`
    Username string `groups:"username" json:"username,omitempty"`
    Nickname string `groups:"nickname" json:"nickname,omitempty"`
}

type User struct {
    ID       int    `groups:"private,public" json:"id,omitempty"`
    Username string `groups:"private" json:"username,omitempty"`
    Nickname string `groups:"public" json:"nickname,omitempty"`
}

var (
    tagName = "groups"
)

//OmitFields sets fields nil by checking their tag group value and access control tags(acTags)
func OmitFields(obj interface{}, acTags []string) {
    //nilV := reflect.Value{}
    sv := reflect.ValueOf(obj).Elem()
    st := sv.Type()
    if sv.Kind() == reflect.Struct {
        for i := 0; i < st.NumField(); i++ {
            fieldVal := sv.Field(i)
            if fieldVal.CanSet() {
                tagStr := st.Field(i).Tag.Get(tagName)
                if len(tagStr) == 0 {
                    continue
                }
                tagList := strings.Split(strings.Replace(tagStr, " ", "", -1), ",")
                //fmt.Println(tagList)
                // ContainsCommonItem checks whether there is at least one common item in arrays
                if !ContainsCommonItem(tagList, acTags) {
                    fieldVal.Set(reflect.Zero(fieldVal.Type()))
                }
            }
        }
    }
}

//ContainsCommonItem checks if arrays have at least one equal item
func ContainsCommonItem(arr1 []string, arr2 []string) bool {
    for i := 0; i < len(arr1); i++ {
        for j := 0; j < len(arr2); j++ {
            if arr1[i] == arr2[j] {
                return true
            }
        }
    }
    return false
}
func main() {
    u := User{ID: 1, Username: "very secret", Nickname: "hinzir"}
    //assume authenticated user doesn't has permission to access private fields
    OmitFields(&u, []string{"public"}) 
    bytes, _ := json.Marshal(&u)
    fmt.Println(string(bytes))


    u2 := User2{ID: 1, Username: "very secret", Nickname: "hinzir"}
    //you want to filter fields by field names
    OmitFields(&u2, []string{"id", "nickname"}) 
    bytes, _ = json.Marshal(&u2)
    fmt.Println(string(bytes))

}

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

I think some concepts from "Advanced Unix Programming" by Marc Rochkind were helpful in understanding the different roles of fork()/exec(), especially for someone used to the Windows CreateProcess() model:

A program is a collection of instructions and data that is kept in a regular file on disk. (from 1.1.2 Programs, Processes, and Threads)

.

In order to run a program, the kernel is first asked to create a new process, which is an environment in which a program executes. (also from 1.1.2 Programs, Processes, and Threads)

.

It’s impossible to understand the exec or fork system calls without fully understanding the distinction between a process and a program. If these terms are new to you, you may want to go back and review Section 1.1.2. If you’re ready to proceed now, we’ll summarize the distinction in one sentence: A process is an execution environment that consists of instruction, user-data, and system-data segments, as well as lots of other resources acquired at runtime, whereas a program is a file containing instructions and data that are used to initialize the instruction and user-data segments of a process. (from 5.3 exec System Calls)

Once you understand the distinction between a program and a process, the behavior of fork() and exec() function can be summarized as:

• fork() creates a duplicate of the current process
• exec() replaces the program in the current process with another program

(this is essentially a simplified 'for dummies' version of paxdiablo's much more detailed answer)

Here's a one-liner using LINQ and avoiding any run-time evaluation of select strings:

someDataTable.Rows.Cast<DataRow>().Where(
    r => r.ItemArray[0] == someValue).ToList().ForEach(r => r.Delete());

If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 then rename the ComponentModelCache folder.

You could simply add a click listener on the map inside the function that creates the InfoWindow

google.maps.event.addListener(marker, 'click', function() {
    var infoWindow = createInfoWindowForMarker(marker);
    infoWindow.open(map, marker);
    google.maps.event.addListener(map, 'click', function() {
        infoWindow.close();
    });
});

with this solution:

for(int i = dtPerson.Rows.Count-1; i >= 0; i--) 
{ 
    DataRow dr = dtPerson.Rows[i]; 
    if (dr["name"] == "Joe")
        dr.Delete();
} 

if you are going to use the datatable after deleting the row, you will get an error. So what you can do is: replace dr.Delete(); with dtPerson.Rows.Remove(dr);

// to string
String text = textField.getText();

// to JTextField
textField.setText(text);

You can also create a new text field: new JTextField(text)

Note that this is not conversion. You have two objects, where one has a property of the type of the other one, and you just set/get it.

Reference: javadocs of JTextField

Try:

git stash
git checkout -b new-branch
git stash apply

git clone git@server:Example/proyect.git

There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.

If you have a long running background work you should specify this by using the correct Task Option.

You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

If you give the following command you'll get the list of activities including commits, merges.

git reflog

Your last commit should probably be at 'HEAD@{0}'. You can check the same with your commit message. To go to that point, use the command

git reset --hard 'HEAD@{0}'

Your merge will be reverted. If in case you have new files left, discard those changes from the merge.

You can also use any(), map() like so:

if any(map(l.startswith, x)):
    pass # Do something

Or alternatively, using a generator expression:

if any(l.startswith(s) for s in x)
    pass # Do something

The compiler doesn't know it's an array, it's trusting the programmer. Deleting a pointer to a single int with delete [] would result in undefined behavior. Your second main() example is unsafe, even if it doesn't immediately crash.

The compiler does have to keep track of how many objects need to be deleted somehow. It may do this by over-allocating enough to store the array size. For more details, see the C++ Super FAQ.

Realised that I was using OpenJDK when I saw this error. Fixed it once I installed the Oracle JDK instead.

If it is a windows form Datagrid, you could use the below code to format the datetime for a column

dataGrid.Columns[2].DefaultCellStyle.Format = "MM/dd/yyyy HH:mm:ss";

EDIT :

Apart from this, if you need the datetime in AM/PM format, you could use the below code

dataGrid.Columns[2].DefaultCellStyle.Format = "MM/dd/yyyy hh:mm:ss tt";

Angular version 6 "0.6.8" rxjs version 6 "^6.0.0"

this solution is for :

  "@angular-devkit/core": "0.6.8",
  "rxjs": "^6.0.0"

as we all know angular is being developed every day so there are lots of changes every day and this solution is for angular 6 and rxjs 6
first to work with http yo should import it from : after all you have to declare the HttpModule in app.module.ts

import { Http } from '@angular/http';

and you have to add HttpModule to Ngmodule -> imports

  imports: [
    HttpModule,
    BrowserModule,
    FormsModule,
    RouterModule.forRoot(appRoutes)
  ],

second to work with map you should first import pipe :

import { pipe } from 'rxjs';

third you need the map function import from :

import { map } from 'rxjs/operators';

you have to use map inside pipe like this exemple :

 constructor(public http:Http){  }

    getusersGET(){
        return this.http.get('http://jsonplaceholder.typicode.com/users').pipe(
         map(res => res.json()  )  );
    }

that works perfectly good luck !

For primitives, if you want to avoid boxing, Guava has helpers for primitive arrays e.g. Ints.indexOf(int[] array, int target)

<style>
form div {
    width: 400px;   
    border: 1px solid black;
} 

form input[type='submit']  {
    display: inline-block;
    width: 70px;
}

div.submitWrapper  {
   text-align: center;    
}    
</style>
<form>

<div class='submitWrapper'>    
<input type='submit' name='submit' value='Submit'> 
 </div>

If you are using Lodash library below is the way to set a dynamic variable in the angular scope.

To set the value in the angular scope.

_.set($scope, the_string, 'life.meaning')

To get the value from the angular scope.

_.get($scope, 'life.meaning')

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

1. you can work with this website for generate favin.ico
2. I recommend use .ico format because the png don't work with method 1 and ico could have more detail!
3. both method work with all browser but when it's automatically work what you want type a code for it? so i think method 1 is better.

Use the SQLite keyword default

db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" 
    + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
    + KEY_NAME + " TEXT NOT NULL, "
    + KEY_WORKED + " INTEGER, "
    + KEY_NOTE + " INTEGER DEFAULT 0);");

This link is useful: http://www.sqlite.org/lang_createtable.html

Confirmed.

The part that drops down is set to either:

1. The height needed to show all entries, or
2. The height needed to show x entries (with scrollbars to see remaining), where x is
   • 20 in Firefox & Chrome
   • 30 in IE 6, 7, 8
   • 16 for Opera 10
   • 14 for Opera 11
   • 22 for Safari 4
   • 18 for Safari 5
   • 11 in IE 5.0, 5.5
3. In IE/Edge, if there are no options, a stupidly high list of 11 blanks entries.

For (3) above you can see the results in this JSFiddle

I wish there was one place to get all of the info about developing your own OS. The closest to come to that is OS Dev Wiki and Forums. They offer a ton of good information regarding the setup, development, and device hardware information.

Also there are some great tutorials at BoneFide, I've used the getting started tutorial by Bran, and am now looking at a more recent one based on his called Roll your own toy UNIX-clone OS.

I second checking out: "Operating Systems : Design and Implementation"

And if you want to develop on Windows, check out jolson's blog post.

Edit: For development on windows using Visual Studio, check out BrokenThorn's guide or OSDev's wiki.

It's quite simple, use Long.valueOf(String s);

For example:

String s;
long l;

Scanner sc=new Scanner(System.in);
s=sc.next();
l=Long.valueOf(s);
System.out.print(l);

You're done!!!

As distributionUrl is still pointing to older version, upgrade wrapper using:

gradle wrapper --gradle-version 5.1.1

Note: Use gradle and not gradlew

add JAVA_HOME to the file:

/etc/environment

for it to be available to the entire system (you would need to restart Ubuntu though)

If the array element is not integer you can use something like below :

$skus  = array('LDRES10','LDRES12','LDRES11');   //sample data

if(!empty($skus)){     
    $sql = "SELECT * FROM `products` WHERE `prodCode` IN ('" . implode("','", $skus) . "') "      
}

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

Before Clustering

After Clustering

I hope this is what you were looking for & this will solve your problem :)

Try something like

find . \( -type f -name \*_peaks.bed -print \) -or \( -type d -and \( -name tmp -or -name scripts \) -and -prune \)

and don't be too surprised if I got it a bit wrong. If the goal is an exec (instead of print), just substitute it in place.

Take a look at the JavaDoc for RestTemplate.

There is the corresponding getForObject methods that are the HTTP GET equivalents of postForObject, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.

Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange methods allow you to provide an HttpEntity object representing the details of the request (including headers). The execute methods allow you to specify a RequestCallback from which you can add the headers upon its invocation.

If anyone looking for a drop-in, zero-config and zero-dependencies library for the above use-case, try pace.js (http://github.hubspot.com/pace/docs/welcome/).

It automatically hooks to events (ajax, readyState, history pushstate, js event loop etc) and show a customizable loader.

Worked well with our react/relay projects (handles navigation changes using react-router, relay requests) (Not affliated; had used pace.js for our projects and it worked great)

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

string ToHex(const string& s, bool upper_case /* = true */)
{
    ostringstream ret;

    for (string::size_type i = 0; i < s.length(); ++i)
        ret << std::hex << std::setfill('0') << std::setw(2) << (upper_case ? std::uppercase : std::nouppercase) << (int)s[i];

    return ret.str();
}

int FromHex(const string &s) { return strtoul(s.c_str(), NULL, 16); }

At the time of writing, setting display:none on the element didn't work for me. Setting the element's width and height to 0 did not work either. So the element has to be at least 1px in width for this to work.

The following example worked in Chrome and Firefox:

    const str = 'Copy me';
    const el = document.createElement("input");
    // Does not work:
    // dummy.style.display = "none";
    el.style.height = '0px';
    // Does not work:
    // el.style.width = '0px';
    el.style.width = '1px';
    document.body.appendChild(el);
    el.value = str;
    el.select();
    document.execCommand("copy");
    document.body.removeChild(el);

I'd like to add that I can see why the browsers are trying to prevent this hackish approach. It's better to openly show the content you are going copy into the user's browser. But sometimes there are design requirements, we can't change.

import UIKit

class DynamicSizeScrollView: UIScrollView {

    var maxHeight: CGFloat = UIScreen.main.bounds.size.height
    var maxWidth: CGFloat = UIScreen.main.bounds.size.width

    override func layoutSubviews() {
        super.layoutSubviews()
        if !__CGSizeEqualToSize(bounds.size,self.intrinsicContentSize){
            self.invalidateIntrinsicContentSize()
        }
    }

    override var intrinsicContentSize: CGSize {
        let height = min(contentSize.height, maxHeight)
        let width = min(contentSize.height, maxWidth)
        return CGSize(width: width, height: height)
    }

}

Linkage determines whether identifiers that have identical names refer to the same object, function, or other entity, even if those identifiers appear in different translation units. The linkage of an identifier depends on how it was declared. There are three types of linkages:

1. Internal linkage : identifiers can only be seen within a translation unit.
2. External linkage : identifiers can be seen (and referred to) in other translation units.
3. No linkage : identifiers can only be seen in the scope in which they are defined. Linkage does not affect scoping

C++ only : You can also have linkage between C++ and non-C++ code fragments, which is called language linkage.

Use Enumerable.Contains function:

var result =
    !(compareString.Contains(firstString) || compareString.Contains(secondString));

Simple answer

If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080

If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.

If you are trying to check the type of an object after you parse a JSON string, I suggest checking the constructor attribute:

obj.constructor == Array || obj.constructor == String || obj.constructor == Object

This will be a much faster check than typeof or instanceof.

If a JSON library does not return objects constructed with these functions, I would be very suspiciouse of it.

it's very simple getting a name:

$('[name=elementname]');

Resource:

http://www.electrictoolbox.com/jquery-form-elements-by-name/ (google search: get element by name jQuery - first result)

I just come across this brilliantly simple solution if you are using .Net 4.5 (not supported this easily in lower versions) and you can use jQuery to make things really simple and painless.

Uploading Multiple Files Using jQuery and Generic Handler in ASP.Net 4.5

Of course there is the commercial version for classic ASP which can be found at ASP Uploader

Try this:

$Wsdl = 'http://xxxx.xxx.xx/webservice3.asmx?WSDL';
libxml_disable_entity_loader(false); //adding this worked for me
$Client = new SoapClient($Wsdl);
//Code...

As all said, you cannot use onLoad event on a DIV instead but it before body tag.

but in case you have one footer file and include it in many pages. it's better to check first if the div you want is on that page displayed, so the code doesn't executed in the pages that doesn't contain that DIV to make it load faster and save some time for your application.

so you will need to give that DIV an ID and do:

var myElem = document.getElementById('myElementId');
if (myElem !== null){ put your code here}

Short answer - Deleted .m2 folder in {user.home}. E.g. in windows 10 user home is C:\Users\user1. Re-build your project using mvn clean package. Only those dependencies would remain, which are required by the projects.

Long Answer - .m2 folder is just like a normal folder and the content of the folder is built from different projects. I think there is no way to figure out automatically that which library is "old". In fact old is a vague word. There could be so many reasons when a previous version of a library is used in a project, hence determining which one is unused is not possible.

All you could do, is to delete the .m2 folder and re-build all of your projects and then the folder would automatically build with all the required library.

If you are concern about only a particular version of a library to be used in all the projects; it is important that the project's pom should also update to latest version. i.e. if different POMs refer different versions of the library, all will get downloaded in .m2.

The question is already answered but I think I've found the solution that is simpler and more relevant to the question title, here it is:

var cli = new WebClient();
cli.Headers[HttpRequestHeader.ContentType] = "application/json";
string response = cli.UploadString("http://some/address", "{some:\"json data\"}");

PS: In the most of .net implementations, but not in all WebClient is IDisposable, so of cource it is better to do 'using' or 'Dispose' on it. However in this particular case it is not really necessary.

xcopy.exe is the solution here. It's built into Windows.

        List<Student> list = query.getResultList();
        return CollectionUtils.isEmpty(list) ? null : list;
    }

}

Assuming maven project: Properties file should be in src/main/resources/database folder

jdbc.properties file

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url

jdbc.password=Your password

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true

ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.

Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.

public interface ServiceMarker {

}

Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker

public interface RepositoryMarker {

}

a.b.c.entities.Student

//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {

    private LocalDateTime fromDate;
    private LocalDateTime toDate;

    //getters setters

}

a.b.c.converters

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {

        if (dateTime == null) {
            return null;
        }
        return Timestamp.valueOf(dateTime);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {

        if (timestamp == null) {
            return null;
        }    
        return timestamp.toLocalDateTime();
    }

It's the response code a SIP User Agent Server (UAS) will send to the client after the client sends a CANCEL request for the original unanswered INVITE request (yet to receive a final response).

Here is a nice CANCEL SIP Call Flow illustration.

$? is the exit status of the most recently-executed command; by convention, 0 means success and anything else indicates failure. That line is testing whether the grep command succeeded.

The grep manpage states:

The exit status is 0 if selected lines are found, and 1 if not found. If an error occurred the exit status is 2. (Note: POSIX error handling code should check for '2' or greater.)

So in this case it's checking whether any ERROR lines were found.

I know this is not really an answer to the question, but it might be worth knowing for someone searching this post. It is also possible to install a Maven repository proxy like nexus.

Your maven would be configured to contact the local Nexus proxy, and Nexus would then retrieve (and cache) the artifacts. It can be configured through a web interface and has support for (http) proxies).

This can be an advantage, especially in a company setting, as artefacts are locally available and can be downloaded fast, and you are not that dependent on the availability of external Maven repositories anymore.

To link back to the question; with Nexus there is a nice GUI for the proxy configuration, and it needs to be done on one place only, and not for every developer.

you forgot to add add alpha1 in module area

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

use maven repository in project area that's it

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

You should apply a "clearfix" to clear the parent element. Next thing, the h4 for the header title, extend all the way across the header, so after you apply clearfix, it will push down the child element causing the header div to have a larger height.

Here is a fix, just replace it with your code.

  <div class="panel-heading clearfix">
     <b>Panel header</b>
       <div class="btn-group pull-right">
        <a href="#" class="btn btn-default btn-sm">## Lock</a>
        <a href="#" class="btn btn-default btn-sm">## Delete</a>
        <a href="#" class="btn btn-default btn-sm">## Move</a>
      </div>
   </div>

Editted on 12/22/2015 - added .clearfix to heading div

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

My privilege prevents me making my comment on the first post so it will have to go here.

Consideration should be taken into account of 2038 unix bug when setting 20 years in advance from the current date which is suggest as the correct answer above.

Your cookie on January 19, 2018 + (20 years) could well hit 2038 problem depending on the browser and or versions you end up running on.

Had the same issue. Not sure if these are the same steps for Windows as I'm using an OS X device but you can try:

1. Reboot your phone into recovery mode.
2. Connect it to your computer.

3. Open the terminal and type:

   cd ~/.android
   adb push adbkey.pub /data/misc/adb/adb_keys
   

4. All done! Just adb shell reboot and feel the power!

The only (easy) way to get cross-domain data using AJAX is to use a server side language as the proxy as Andy E noted. Here's a small sample how to implement that using jQuery:

The jQuery part:

$.ajax({
    url: 'proxy.php',
    type: 'POST',
    data: {
        address: 'http://www.google.com'
    },
    success: function(response) {
        // response now contains full HTML of google.com
    }
});

And the PHP (proxy.php):

echo file_get_contents($_POST['address']);

Simple as that. Just be aware of what you can or cannot do with the scraped data.

I was facing exactly the same problem. With Windows Vista I could not reproduce the problem but on Ubuntu I reproduced the 'connection reset'-Error constantly.

I found http://forums.oracle.com/forums/thread.jspa?threadID=941911&tstart=0&messageID=3793101

According to a user on that forum:

I opened a ticket with Oracle and this is what they told me.

java.security.SecureRandom is a standard API provided by sun. Among various methods offered by this class void nextBytes(byte[]) is one. This method is used for generating random bytes. Oracle 11g JDBC drivers use this API to generate random number during login. Users using Linux have been encountering SQLException("Io exception: Connection reset").

The problem is two fold

1. The JVM tries to list all the files in the /tmp (or alternate tmp directory set by -Djava.io.tmpdir) when SecureRandom.nextBytes(byte[]) is invoked. If the number of files is large the method takes a long time to respond and hence cause the server to timeout

2. The method void nextBytes(byte[]) uses /dev/random on Linux and on some machines which lack the random number generating hardware the operation slows down to the extent of bringing the whole login process to a halt. Ultimately the the user encounters SQLException("Io exception: Connection reset")

Users upgrading to 11g can encounter this issue if the underlying OS is Linux which is running on a faulty hardware.

Cause The cause of this has not yet been determined exactly. It could either be a problem in your hardware or the fact that for some reason the software cannot read from dev/random

Solution Change the setup for your application, so you add the next parameter to the java command:

-Djava.security.egd=file:/dev/../dev/urandom

We made this change in our java.security file and it has gotten rid of the error.

which solved my problem.

As you stated, package names are usually in the form of 'com.organizationName.appName' - all lowercase and no spaces. It sounds like the package name that you entered when uploading the app was different from the one declared in the AndroidManifest.

You need to add this value to the form data that is submitted to the server. You can use

<input type="hidden" value="1" name="profile_viewer_uid" id="profile_viewer_uid">

inside your form tag.

find -type f -print0 | xargs -0 ls -t

Drawback: Works only to a certain amount of files. If you have extremly large amounts of files you need something more complicated

If you are trying to use below example

Example: { value1: "value1" }

And add conditionalData dynamically based on some condition, Try

let dataToWrite: any = {value1: "value1"};

if(conditionalData)
   dataToWrite["conditionalData"] = conditionalData

There is no CREATE TABLE IF NOT EXISTS... but you can write a simple procedure for that, something like:

CREATE OR REPLACE FUNCTION prc_create_sch_foo_table() RETURNS VOID AS $$
BEGIN

EXECUTE 'CREATE TABLE /* IF NOT EXISTS add for PostgreSQL 9.1+ */ sch.foo (
                    id serial NOT NULL, 
                    demo_column varchar NOT NULL, 
                    demo_column2 varchar NOT NULL,
                    CONSTRAINT pk_sch_foo PRIMARY KEY (id));
                   CREATE INDEX /* IF NOT EXISTS add for PostgreSQL 9.5+ */ idx_sch_foo_demo_column ON sch.foo(demo_column);
                   CREATE INDEX /* IF NOT EXISTS add for PostgreSQL 9.5+ */ idx_sch_foo_demo_column2 ON sch.foo(demo_column2);'
               WHERE NOT EXISTS(SELECT * FROM information_schema.tables 
                        WHERE table_schema = 'sch' 
                            AND table_name = 'foo');

         EXCEPTION WHEN null_value_not_allowed THEN
           WHEN duplicate_table THEN
           WHEN others THEN RAISE EXCEPTION '% %', SQLSTATE, SQLERRM;

END; $$ LANGUAGE plpgsql;

Here's a simple and working method I found elsewhere:

string hexString = "7FF";
int hexNumber;
sscanf(hexString.c_str(), "%x", &hexNumber);

Please note that you might prefer using unsigned long integer/long integer, to receive the value. Another note, the c_str() function just converts the std::string to const char* .

So if you have a const char* ready, just go ahead with using that variable name directly, as shown below [I am also showing the usage of the unsigned long variable for a larger hex number. Do not confuse it with the case of having const char* instead of string]:

const char *hexString = "7FFEA5"; //Just to show the conversion of a bigger hex number
unsigned long hexNumber; //In case your hex number is going to be sufficiently big.
sscanf(hexString, "%x", &hexNumber);

This works just perfectly fine (provided you use appropriate data types per your need).

Simplest Solution

After scouring different solutions on SO, I found the following to be the simplest and cleanest solution for populating a Spinner with custom Objects. Here's the full implementation:

User.java

public class User{
    public int ID;
    public String name;

    @Override
    public String toString() {
        return this.name; // What to display in the Spinner list.
    }
}    

res/layout/spinner.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:textSize="14sp"
    android:textColor="#FFFFFF"
    android:spinnerMode="dialog" />

res/layout/your_activity_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

    <Spinner android:id="@+id/user" />

</LinearLayout>

In Your Activity

List<User> users = User.all(); // This example assumes you're getting all Users but adjust it for your Class and needs.
ArrayAdapter userAdapter = new ArrayAdapter(this, R.layout.spinner, users);

Spinner userSpinner = (Spinner) findViewById(R.id.user);
userSpinner.setAdapter(userAdapter);
userSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        // Get the value selected by the user
        // e.g. to store it as a field or immediately call a method
        User user = (User) parent.getSelectedItem();
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
    }
});

There is not 'goto' in the Java world. The main reason was developers realized that complex codes which had goto would lead to making the code really pathetic and it would be almost impossible to enhance or maintain the code.

However this code could be modified a little and using the concept of continue and break we could make the code work.

    import java.util.*;

public class Factorial 
{
    public static void main(String[] args) 
    {
        int x = 1;
        int factValue = 1;
        Scanner userInput = new Scanner(System.in);
        restart: while(true){
        System.out.println("Please enter a nonzero, nonnegative value to be factorialized.");
        int factInput = userInput.nextInt();

        while(factInput<=0)
        {
            System.out.println("Enter a nonzero, nonnegative value to be factorialized.");
            factInput = userInput.nextInt();
        }

        if(x<1)//This is another way of doing what the above while loop does, I just wanted to have some fun.
        {
            System.out.println("The number you entered is not valid. Please try again.");
            continue restart;
        }
        while(x<=factInput)
        {
            factValue*=x;
            x++;
        }
        System.out.println(factInput+"! = "+factValue);
        userInput.close();
        break restart;
}
    }
}

Vladimir's answer is perfect, but anyone like me who is looking for swift solution

This Solution is Worked for swift version 4.2

var i = 0
    func animation(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        myImageView.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: .easeInEaseOut)
        transition.type = .fade
        myImageView.layer.add(transition, forKey: nil)
        i += 1
    }

You can call this method from anywhere. It will change the image to next one(image) with animation.

For Swift Version 4.0 Use bellow solution

var i = 0
    func animationVersion4(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        uiImage.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionFade
        uiImage.layer.add(transition, forKey: nil)
        i += 1
    }

To expand on Solomon Rutzky's answer, if you are looking for a piece of data that shows up in a range (i.e. more than once but less than 5x), you can use

having count(*) > 1 and count(*) < 5

And you can use whatever qualifiers you desire in there - they don't have to match, it's all just included in the 'having' statement. https://webcheatsheet.com/sql/interactive_sql_tutorial/sql_having.php

[float(i) for i in lst]

to be precise, it creates a new list with float values. Unlike the map approach it will work in py3k.

Knowing how to write a preset dictionary is useful to know as well:

cmap =  {'US':'USA','GB':'Great Britain'}

# Explicitly:
# -----------
def cxlate(country):
    try:
        ret = cmap[country]
    except KeyError:
        ret = '?'
    return ret

present = 'US' # this one is in the dict
missing = 'RU' # this one is not

print cxlate(present) # == USA
print cxlate(missing) # == ?

# or, much more simply as suggested below:

print cmap.get(present,'?') # == USA
print cmap.get(missing,'?') # == ?

# with country codes, you might prefer to return the original on failure:

print cmap.get(present,present) # == USA
print cmap.get(missing,missing) # == RU

I wanted to display the login page without the layout and this works pretty good for me.(this is the _ViewStart.cshtml file) You need to set the ViewBag.Title in the Controller.

@{
    if (! (ViewContext.ViewBag.Title == "Login"))
    {
        Layout = "~/Views/Shared/_Layout.cshtml";        
    } 
}

I know it's a little bit late but I hope this helps some body.

check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js

Also, if you have Toad for Oracle, you can highlight the statement and press CTRL + F9 and you'll get a nice view of column and their datatypes.

A way to replace it with a java 8 stream:

public static void main(String[] args) throws IOException
{
    String test = "ab19198zxncvl1308j10923.";
    StringBuilder result = new StringBuilder();

    test.chars().mapToObj( i-> (char)i ).filter( c -> Character.isDigit(c) || c == '.' ).forEach( c -> result.append(c) );

    System.out.println( result ); //returns 19198.130810923.
}

Just thinking you might be feel unfamiliar of the sequence From->Where->Select, as in sql script, it is like Select->From->Where.

But you may not know that inside Sql Engine, it is also parse in the sequence of 'From->Where->Select', To validate it, you can try a simple script

select id as i from table where i=3

and it will not work, the reason is engine will parse Where before Select, so it won't know alias i in the where. To make this work, you can try

select * from (select id as i from table) as t where i = 3

In python "else if" is spelled "elif".
Also, you need a colon after the elif and the else.

Simple answer to a simple question. I had the same problem, when I first started (in the last couple of weeks).

So your code should read:

def function(a):
    if a == '1':
        print('1a')
    elif a == '2':
        print('2a')
    else:
        print('3a')

function(input('input:'))

Content is what is passed as children. View is the template of the current component.

The view is initialized before the content and ngAfterViewInit() is therefore called before ngAfterContentInit().

** ngAfterViewInit() is called when the bindings of the children directives (or components) have been checked for the first time. Hence its perfect for accessing and manipulating DOM with Angular 2 components. As @Günter Zöchbauer mentioned before is correct @ViewChild() hence runs fine inside it.

Example:

@Component({
    selector: 'widget-three',
    template: `<input #input1 type="text">`
})
export class WidgetThree{
    @ViewChild('input1') input1;

    constructor(private renderer:Renderer){}

    ngAfterViewInit(){
        this.renderer.invokeElementMethod(
            this.input1.nativeElement,
            'focus',
            []
        )
    }
}

For bash and other Bourne-like shells:

java com.myserver.Program "$@"

Just do git checkout path/to/file-I-want-to-bring-back.txt

Note that COLUMNS is:

1. NOT an environment variable. It is an ordinary bash parameter that is set by bash itself.
2. Set automatically upon receipt of a SIGWINCH signal.

That second point usually means that your COLUMNS variable will only be set in your interactive shell, not in a bash script.

If your script's stdin is connected to your terminal you can manually look up the width of your terminal by asking your terminal:

tput cols

And to use this in your SVN command:

svn diff "$@" --diff-cmd /usr/bin/diff -x "-y -w -p -W $(tput cols)"

(Note: you should quote "$@" and stay away from eval ;-))

try to put the path in the system variables instead of putting in user variables in environment variables.

There's an excellent module for flow control in node.js called asyncblock. If wrapping the code in a function is OK for your case, the following sample may be considered:

var asyncblock = require('asyncblock');
var exec = require('child_process').exec;

asyncblock(function (flow) {
    exec('node -v', flow.add());
    result = flow.wait();
    console.log(result);    // There'll be trailing \n in the output

    // Some other jobs
    console.log('More results like if it were sync...');
});

This is the solution for mobile safari:

-webkit-appearance: none;

as suggested here: Remove textarea inner shadow on Mobile Safari (iPhone)

I'm not sure if you're going to get any huge gains for reasons Jon Skeet pointed out. However, you could try and benchmark the TypeConvert.ConvertTo method and see how it compares to using your current method.

ImageConverter converter = new ImageConverter();
byte[] imgArray = (byte[])converter.ConvertTo(imageIn, typeof(byte[]));

But the real answer is: other than the ORDER BY clause, the sort order will by arbitrary and not guaranteed.

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

for the remote access.

The documentation is quite sketchy as far as definitive resolutions go. After some research, here's the solution I came to: Android splash screen image sizes to fit all devices

It's basically guided towards splash screens, but it's perfectly applicable to images that should occupy full screen.

Do not use strtok() in normal code, strtok() uses static variables which have some problems. There are some use cases on embedded microcontrollers where static variables make sense but avoid them in most other cases. strtok() behaves unexpected when more than 1 thread uses it, when it is used in a interrupt or when there are some other circumstances where more than one input is processed between successive calls to strtok(). Consider this example:

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

//Splits the input by the / character and prints the content in between
//the / character. The input string will be changed
void printContent(char *input)
{
    char *p = strtok(input, "/");
    while(p)
    {
        printf("%s, ",p);
        p = strtok(NULL, "/");
    }
}

int main(void)
{
    char buffer[] = "abc/def/ghi:ABC/DEF/GHI";
    char *p = strtok(buffer, ":");
    while(p)
    {
        printContent(p);
        puts(""); //print newline
        p = strtok(NULL, ":");
    }
    return 0;
}

You may expect the output:

abc, def, ghi,
ABC, DEF, GHI,

But you will get

abc, def, ghi,

This is because you call strtok() in printContent() resting the internal state of strtok() generated in main(). After returning, the content of strtok() is empty and the next call to strtok() returns NULL.

What you should do instead

You could use strtok_r() when you use a POSIX system, this versions does not need static variables. If your library does not provide strtok_r() you can write your own version of it. This should not be hard and Stackoverflow is not a coding service, you can write it on your own.

Since -f caused another problem, I developed another solution.

• Create a base image in the parent folder
• Added the required files.
• Used this image as a base image for the project which in a descendant folder.

The -f flag does not solved my problem because my onbuild image looks for a file in a folder and had to call like this:

-f foo/bar/Dockerfile foo/bar

instead of

-f foo/bar/Dockerfile .

Also note that this is only solution for some cases as -f flag

This is a revised solution that will also work for modal windows rendered using a Grails template, where you can have the same modal template called multiple times (with different values) in the same body. This thread helped me immensely, so I thought I'd share it in case other Grails users found their way here.

For those who are curious, the accepted solution didn't work for me because I am rendering a table; each row has a button that opens a modal window with more details about the record. This led to multiple printSection divs being created and printed on top of each other. Therefore I had to revise the js to clean up the div after it was done printing.

CSS

I added this CSS directly to my modal gsp, but adding it to the parent has the same effect.

<style type="text/css">
   @media screen {
        #printSection {
           display: none;
        }
   }

   @media print {
        body > *:not(#printSection) {
           display: none;
        }
        #printSection, #printSection * {
            visibility: visible;
        }
        #printSection {
            position:absolute;
            left:0;
            top:0;
        }
   }
</style>

Adding it to the site-wide CSS killed the print functionality in other parts of the site. I got this from ComFreak's accepted answer (based on Bennett McElwee answer), but it is revised using ':not' functionality from fanfavorite's answer on Print <div id=printarea></div> only? . I opted for 'display' rather than 'visibility' because my invisible body content was creating extra blank pages, which was unacceptable to my users.

js

And this to my javascript, revised from ComFreak's accepted answer to this question.

function printDiv(div) {    
    // Create and insert new print section
    var elem = document.getElementById(div);
    var domClone = elem.cloneNode(true);
    var $printSection = document.createElement("div");
    $printSection.id = "printSection";
    $printSection.appendChild(domClone);
    document.body.insertBefore($printSection, document.body.firstChild);

    window.print(); 

    // Clean up print section for future use
    var oldElem = document.getElementById("printSection");
    if (oldElem != null) { oldElem.parentNode.removeChild(oldElem); } 
                          //oldElem.remove() not supported by IE

    return true;
}

I had no need for appending elements, so I removed that aspect and changed the function to specifically print a div.

HTML (gsp)

And the modal template. This prints the modal header & body and excludes the footer, where the buttons were located.

<div class="modal-content">
    <div id="print-me"> <!-- This is the div that is cloned and printed -->
        <div class="modal-header">
            <!-- HEADER CONTENT -->
        </div>
        <div class="modal-body">
             <!-- BODY CONTENT -->
        </div>
    </div>
    <div class="modal-footer">
                                 <!-- This is where I specify the div to print -->
        <button type="button" class="btn btn-default" onclick="printDiv('print-me')">Print</button>
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    </div>
</div>

I hope that helps someone!

Tensorflow 2.0 Compatible Answer: In Tensorflow Version >= 2.0, the command for Initializing all the Variables if we use Graph Mode, to fix the FailedPreconditionError is shown below:

tf.compat.v1.global_variables_initializer

This is just a shortcut for variables_initializer(global_variables())

It returns an Op that initializes global variables in the graph.

While most answers are a copy of SolutionYogi's answer, they all miss an important check to see if 'cell' is not null which will return an error if clicking on the headers. So, here is the answer with the check included:

function addRowHandlers() {
  var table = document.getElementById("tableId");
  var rows = table.getElementsByTagName("tr");
  for (i = 0; i < rows.length; i++) {
    var currentRow = table.rows[i];
    var createClickHandler = function(row) {
      return function() {
        var cell = row.getElementsByTagName("td")[0];
        // check if not null
        if(!cell) return; // no errors! 
        var id = cell.innerHTML;
        alert("id:" + id);
      };
    };
    currentRow.onclick = createClickHandler(currentRow);
  }
}

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:

plt.axes[0].get_lines()[0].set_color('black')

The default location for python.exe should be here: c:\users\xxx\anaconda3 One solution to find where it is, is to open the Anaconda Prompt then execute:

> where python

This will return the absolute path of locations of python eg:

(base) C:\>where python
C:\Users\Chad\Anaconda3\python.exe
C:\ProgramData\Miniconda2\python.exe
C:\dev\Python27\python.exe
C:\dev\Python34\python.exe

If you are not bothered about the location of the text present, then you could use Driver.PageSource property as below:

Driver.PageSource.Contains("expected message");

to disable back function of the back button:

window.addEventListener('popstate', function (event) {
  history.pushState(null, document.title, location.href);
});

This is a simple way to call notification by using default vibrate and sound from system.

private void sendNotification(String message, String tick, String title, boolean sound, boolean vibrate, int iconID) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    Notification notification = new Notification();

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);

    if (sound) {
        notification.defaults |= Notification.DEFAULT_SOUND;
    }

    if (vibrate) {
        notification.defaults |= Notification.DEFAULT_VIBRATE;
    }

    notificationBuilder.setDefaults(notification.defaults);
    notificationBuilder.setSmallIcon(iconID)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setTicker(tick)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

Add vibrate permission if you are going to use it:

<uses-permission android:name="android.permission.VIBRATE"/>

Good luck,'.

Here's how

String details = "Hello \"world\"!";
details = details.replace("\"","\\\"");
System.out.println(details);               // Hello \"world\"!

Note that strings are immutable, thus it is not sufficient to simply do details.replace("\"","\\\""). You must reassign the variable details to the resulting string.

Using

details = details.replaceAll("\"","&quote;");

instead, results in

Hello &quote;world&quote;!

This and the next steps are described in a blog entry.

I found that that when I have two Get methods, one parameterless and one with a complex type as a parameter that I got the same error. I solved this by adding a dummy parameter of type int, named Id, as my first parameter, followed by my complex type parameter. I then added the complex type parameter to the route template. The following worked for me.

First get:

public IEnumerable<SearchItem> Get()
{
...
}

Second get:

public IEnumerable<SearchItem> Get(int id, [FromUri] List<string> layers)
{
...
}

WebApiConfig:

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}/{layers}",
    defaults: new { id = RouteParameter.Optional, layers RouteParameter.Optional }
);

Tha is because getColumnDimensionByColumn receives the column index (an integer starting from 0), not a string.

The same goes for setCellValueByColumnAndRow

You can create a dynamic table rows as below:

var tbl = document.createElement('table');
tbl.style.width = '100%';

for (var i = 0; i < files.length; i++) {

        tr = document.createElement('tr');

        var td1 = document.createElement('td');
        var td2 = document.createElement('td');
        var td3 = document.createElement('td');

        ::::: // As many <td> you want

        td1.appendChild(document.createTextNode());
        td2.appendChild(document.createTextNode());
        td3.appendChild(document.createTextNode();

        tr.appendChild(td1);
        tr.appendChild(td2);
        tr.appendChild(td3);

        tbl.appendChild(tr);
}

I would recommend using my own script, which solves this problem. It also has options to change the encoding of the file names, and to convert combining diacriticals to precomposed characters, a problem I always have when I copy files from my Mac.

You could do something like this if you wanted

package main

import "fmt"

type Pair struct {
    a, b interface{}
}

func main() {
    p1 := Pair{"finished", 42}
    p2 := Pair{6.1, "hello"}
    fmt.Println("p1=", p1, "p2=", p2)
    fmt.Println("p1.b", p1.b)
    // But to use the values you'll need a type assertion
    s := p1.a.(string) + " now"
    fmt.Println("p1.a", s)
}

However I think what you have already is perfectly idiomatic and the struct describes your data perfectly which is a big advantage over using plain tuples.

With swift syntax this worked for me :

    let leftImageView = UIImageView()
    leftImageView.image = UIImage(named: "email")

    let leftView = UIView()
    leftView.addSubview(leftImageView)

    leftView.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
    leftImageView.frame = CGRect(x: 10, y: 10, width: 20, height: 20)
    userNameTextField.leftViewMode = .always
    userNameTextField.leftView = leftView

$elapsed = '2592000';
// Time in the past
$time_past = '2014-07-16 11:35:33';
$time_past = strtotime($time_past);

// Add a month to that time
$time_past = $time_past + $elapsed;

// Time NOW
$time_now = time();

// Check if its been a month since time past
if($time_past > $time_now){
    echo 'Hasnt been a month';    
}else{
    echo 'Been longer than a month';
}

We have a similar situation at work, where the production machines have no access to the Internet; therefore everything has to be managed offline and off-host.

Here is what I tried with varied amounts of success:

1. basket which is a small utility that you run on your internet-connected host. Instead of trying to install a package, it will instead download it, and everything else it requires to be installed into a directory. You then move this directory onto your target machine. Pros: very easy and simple to use, no server headaches; no ports to configure. Cons: there aren't any real showstoppers, but the biggest one is that it doesn't respect any version pinning you may have; it will always download the latest version of a package.

2. Run a local pypi server. Used pypiserver and devpi. pypiserver is super simple to install and setup; devpi takes a bit more finagling. They both do the same thing - act as a proxy/cache for the real pypi and as a local pypi server for any home-grown packages. localshop is a new one that wasn't around when I was looking, it also has the same idea. So how it works is your internet-restricted machine will connect to these servers, they are then connected to the Internet so that they can cache and proxy the actual repository.

The problem with the second approach is that although you get maximum compatibility and access to the entire repository of Python packages, you still need to make sure any/all dependencies are installed on your target machines (for example, any headers for database drivers and a build toolchain). Further, these solutions do not cater for non-pypi repositories (for example, packages that are hosted on github).

We got very far with the second option though, so I would definitely recommend it.

Eventually, getting tired of having to deal with compatibility issues and libraries, we migrated the entire circus of servers to commercially supported docker containers.

This means that we ship everything pre-configured, nothing actually needs to be installed on the production machines and it has been the most headache-free solution for us.

We replaced the pypi repositories with a local docker image server.

In Java 8, it's now as simple as:

movieItems.sort(Comparator.comparing(Movie::getDate));

"all" is a default setting, even though Behaviour->Build (Incremental build) tab has no variable. I solved as

1. Go to Project Properties > C/C++ Build > Behaviour Tab.
2. Leave Build (Incremental Build) Checked.
3. Enter "test" in the text box next to Build (Incremental Build).
4. Build Project. You will see error message.
5. Go back to Build (Incremental Build) and delete "test".
6. Build Project.

DateAdd(m,1,reference_dt)

will add a month to the column value

If you are using this path to access parts of the projects which are not code (for example an upload directory, or a SQLite database) then it might be better to turn the path into a parameter, like this:

parameters:
    database_path: '%kernel.root_dir%/../var/sqlite3.db'

This parameter can be injected everywhere you need it, so you don't have to mess around with paths in your code any more. Also, the parameter can be overridden at deployment time. Finally, every maintaining programmer will have a better idea what you are using it for.

Update: Fixed kernel.root_dir constant usage.

As far as I'm concerned the best solution is using GetValueOrDefault() method.

v2 = v1.GetValueOrDefault();

Try putting the z-index of your datepicker css a lot higher (eg z-index: 1000). The datepicker is probably shown under your original content. I had the same problem and this helped me out.

You could do:

var matchingDog = AllDogs.FirstOrDefault(dog => dog.Id == "2"));

This will return the matching dog, else it will return null.

You can then set the property like follows:

if (matchingDog != null)
    matchingDog.Name = "New Dog Name";

String text = readFileAsString("textfile.txt");
text = text.replace("\n", "").replace("\r", "");

Using the return codes from net start and net stop seems like the best method to me. Try a look at this: Net Start return codes.

What you want is Themes. They're important for a lot more than the AppBar color.

Put it inside your <footer> by all means, but the most fitting element is the small element.

The HTML5 spec for this says:

Small print typically features disclaimers, caveats, legal restrictions, or copyrights. Small print is also sometimes used for attribution, or for satisfying licensing requirements.

I think the easiest solution is to set android:animateLayoutChanges="true" to your LinearLayout and then just show/hide view by seting its visibility. Works like a charm, but you have no controll on the animation duration

clone() was designed with several mistakes (see this question), so it's best to avoid it.

From Effective Java 2nd Edition, Item 11: Override clone judiciously

Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.

This book also describes the many advantages copy constructors have over Cloneable/clone.

• They don't rely on a risk-prone extralinguistic object creation mechanism
• They don't demand unenforceable adherence to thinly documented conventions
• They don't conflict with the proper use of final fields
• They don't throw unnecessary checked exceptions
• They don't require casts.

All standard collections have copy constructors. Use them.

List<Double> original = // some list
List<Double> copy = new ArrayList<Double>(original);

CORS angular js + restEasy on POST

Well finally I came to this workaround: The reason it worked with IE is because IE sends directly a POST instead of first a preflight request to ask for permission. But I still don't know why the filter wasn't able to manage an OPTIONS request and sends by default headers that aren't described in the filter (seems like an override for that only case ... maybe a restEasy thing ...)

So I created an OPTIONS path in my rest service that rewrites the reponse and includes the headers in the response using response header

I'm still looking for the clean way to do it if anybody faced this before.

Check the ExcelPackage project, it uses the Office Open XML file format of Excel 2007, it's lightweight and open source...

The tables you are looking for are probably in a different schema. There are a couple of options. You can either click on Other Users in the tree under your connection, or right click on the connection and select Schema Browser and then select the desired schema.

Another alternative is to use a lambda:

ent.bind("<Return>", (lambda event: name_of_function()))

Full code:

from tkinter import *
from tkinter.messagebox import showinfo

def reply(name):
    showinfo(title="Reply", message = "Hello %s!" % name)


top = Tk()
top.title("Echo")
top.iconbitmap("Iconshock-Folder-Gallery.ico")

Label(top, text="Enter your name:").pack(side=TOP)
ent = Entry(top)
ent.bind("<Return>", (lambda event: reply(ent.get())))
ent.pack(side=TOP)
btn = Button(top,text="Submit", command=(lambda: reply(ent.get())))
btn.pack(side=LEFT)

top.mainloop()

As you can see, creating a lambda function with an unused variable "event" solves the problem.

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

To clear the SQL window you can use:

clear screen;

which can also be shortened to

cl scr;

You can use CSS3 filters. They are relatively easy to implement, though are only supported on webkit at the minute. Samsung Galaxy 2's browser should support though, as I think that's a webkit browser?

Here's a similar answer using using a => style function:

var data = [1,2,3,4];
data.forEach( (item, i, self) => self[i] = item + 10 );

gives the result:

[11,12,13,14]

The self parameter isn't strictly necessary with the arrow style function, so

data.forEach( (item,i) => data[i] = item + 10);

also works.

I would suggest you to write extension, something like below.

public static class WriteToConsoleExtension
{
   // Extension to all types
   public static void WriteToConsole(this object instance, 
                                     string format, 
                                     params object[] data)
   {
       Console.WriteLine(format, data);
   }
}

class Program
{
    static void Main(string[] args)
    {
        Program p = new Program();
        // Usage of extension
        p.WriteToConsole("Test {0}, {1}", DateTime.Now, 1);
    }
}

Hope this helps (and not too late :) )

You can get around that limit by using subst if you need to.

Joining the party late, but just as a complement, I ran into some problems with Seaborn not so long ago, because CoLab installed a version with !pip that wasn't updated. In my specific case, I couldn't use Scatterplot, for example. The answer to this is below:

To install the module, all you need is:

!pip install seaborn

To upgrade it to the most updated version:

!pip install --upgrade seaborn

If you want to install a specific version

!pip install seaborn==0.9.0

I believe all the rules common to pip apply normally, so that pretty much should work.

This is an interesting question and touches on a very basic concept in Bourne shell and subshell. Here I provide a solution that is different from the previous solutions by doing some kind of filtering. I will give an example that may be useful in real life. This is a fragment for checking that downloaded files conform to a known checksum. The checksum file look like the following (Showing just 3 lines):

49174 36326 dna_align_feature.txt.gz
54757     1 dna.txt.gz
55409  9971 exon_transcript.txt.gz

The shell script:

#!/bin/sh

.....

failcnt=0 # this variable is only valid in the parent shell
#variable xx captures all the outputs from the while loop
xx=$(cat ${checkfile} | while read -r line; do
    num1=$(echo $line | awk '{print $1}')
    num2=$(echo $line | awk '{print $2}')
    fname=$(echo $line | awk '{print $3}')
    if [ -f "$fname" ]; then
        res=$(sum $fname)
        filegood=$(sum $fname | awk -v na=$num1 -v nb=$num2 -v fn=$fname '{ if (na == $1 && nb == $2) { print "TRUE"; } else { print "FALSE"; }}')
        if [ "$filegood" = "FALSE" ]; then
            failcnt=$(expr $failcnt + 1) # only in subshell
            echo "$fname BAD $failcnt"
        fi
    fi
done | tail -1) # I am only interested in the final result
# you can capture a whole bunch of texts and do further filtering
failcnt=${xx#* BAD } # I am only interested in the number
# this variable is in the parent shell
echo failcnt $failcnt
if [ $failcnt -gt 0 ]; then
    echo $failcnt files failed
else
    echo download successful
fi

The parent and subshell communicate through the echo command. You can pick some easy to parse text for the parent shell. This method does not break your normal way of thinking, just that you have to do some post processing. You can use grep, sed, awk, and more for doing so.

I edit cybergen answer for make viewpager to change height depending on selected item The class is the same of cybergen's, but I added a Vector of integers that is all viewpager's child views heights and we can access it when page change to update height

This is the class:

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.viewpager.widget.ViewPager;

import java.util.Vector;

public class WrapContentHeightViewPager extends ViewPager {
    private Vector<Integer> heights = new Vector<>();

    public WrapContentHeightViewPager(@NonNull Context context) {
        super(context);
    }

    public WrapContentHeightViewPager(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        for(int i=0;i<getChildCount();i++) {
            View view = getChildAt(i);
            if (view != null) {
                view.measure(widthMeasureSpec, heightMeasureSpec);
                heights.add(measureHeight(heightMeasureSpec, view));
            }
        }
        setMeasuredDimension(getMeasuredWidth(), measureHeight(heightMeasureSpec, getChildAt(0)));
    }

    public int getHeightAt(int position){
        return heights.get(position);
    }

    private int measureHeight(int measureSpec, View view) {
        int result = 0;
        int specMode = MeasureSpec.getMode(measureSpec);
        int specSize = MeasureSpec.getSize(measureSpec);

        if (specMode == MeasureSpec.EXACTLY) {
            result = specSize;
        } else {
            if (view != null) {
                result = view.getMeasuredHeight();
            }
            if (specMode == MeasureSpec.AT_MOST) {
                result = Math.min(result, specSize);
            }
        }
        return result;
    }
}

Then in your activity add an OnPageChangeListener

WrapContentHeightViewPager viewPager = findViewById(R.id.my_viewpager);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
     @Override
     public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}
     @Override
     public void onPageSelected(int position) {
         LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) viewPager.getLayoutParams();
         params.height = viewPager.getHeightAt(position);
         viewPager.setLayoutParams(params);
     }
     @Override
     public void onPageScrollStateChanged(int state) {}
});

And here is xml:

<com.example.example.WrapContentHeightViewPager
    android:id="@+id/my_viewpager"
    android:fillViewport="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Please correct my English if necessary

try this out let me know what happens.

Form:

<form action="form.php" method="post"> 
Search: <input type="text" name="term" /><br /> 
<input type="submit" value="Submit" /> 
</form> 

Form.php:

$term = mysql_real_escape_string($_REQUEST['term']);    

$sql = "SELECT * FROM liam WHERE Description LIKE '%".$term."%'";
$r_query = mysql_query($sql);

while ($row = mysql_fetch_array($r_query)){ 
echo 'Primary key: ' .$row['PRIMARYKEY']; 
echo '<br /> Code: ' .$row['Code']; 
echo '<br /> Description: '.$row['Description']; 
echo '<br /> Category: '.$row['Category']; 
echo '<br /> Cut Size: '.$row['CutSize'];  
} 

Edit: Cleaned it up a little more.

Final Cut (my test file):

<?php
$db_hostname = 'localhost';
$db_username = 'demo';
$db_password = 'demo';
$db_database = 'demo';

// Database Connection String
$con = mysql_connect($db_hostname,$db_username,$db_password);
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db($db_database, $con);
?>

Got the same issue where IIS express complained about http://localhost:50418/ and none of above solutions worked for me..

Went to projektFolder --> .vs --> config --> applicationhost.xml

In the tag <sites> I found that my web app had two bindnings registered.

<site name="myApp.Web" id="2">
    <application path="/" applicationPool="Clr4IntegratedAppPool">
        <virtualDirectory path="/" physicalPath="C:\git\myApp\myApp.Web" />
    </application>
    <bindings>
        <binding protocol="https" bindingInformation="*:44332:localhost" />
        <binding protocol="http" bindingInformation="*:50418:localhost" />
    </bindings>
</site>

Removing the binding pointing to *:50418:localhost solved the issue.

Using VS2017 and IISExpress v10.

CASE WHEN is the better option

SELECT 
  CASE WHEN COLUMN1 = COLUMN2 
    THEN '1' 
    ELSE '0' 
  END 
  AS MyDesiredResult
FROM Table1
INNER JOIN Table2 ON Table1.PrimaryKey = Table2.ForeignKey

A (somewhat) different way:

reduce(lambda acc, x: acc + (1 if x > 5 else 0), j, 0)

I develop on Windows and Mac/Linux at the same time and I avoid this ^M-error by simply running my scripts as I do in Windows:

$ php ./my_script

No need to change line endings.

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

TCP

I will not send data anymore until i get an acknowledgment.

this process is slow

It is used for security purpose

example: web, sending mail, receiving mail etc

UDP

Here i have no headache with acknowledgment.

this process is faster but here data can be lost .

example : video streaming , online games etc

TCP + UDP = SMTP(example : mobile,telephone)
