You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

newString = yourString.Substring(0, yourString.length -1);

Never try to set the compiler in the CMakeLists.txt file.

See the CMake FAQ about how to use a different compiler:

https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler

(Note that you are attempting method #3 and the FAQ says "(avoid)"...)

We recommend avoiding the "in the CMakeLists" technique because there are problems with it when a different compiler was used for a first configure, and then the CMakeLists file changes to try setting a different compiler... And because the intent of a CMakeLists file should be to work with multiple compilers, according to the preference of the developer running CMake.

The best method is to set the environment variables CC and CXX before calling CMake for the very first time in a build tree.

After CMake detects what compilers to use, it saves them in the CMakeCache.txt file so that it can still generate proper build systems even if those variables disappear from the environment...

If you ever need to change compilers, you need to start with a fresh build tree.

try this is your activity onCreate:

ScrollView sView = (ScrollView)findViewById(R.id.deal_web_view_holder);
// Hide the Scollbar
sView.setVerticalScrollBarEnabled(false);
sView.setHorizontalScrollBarEnabled(false);

http://developer.android.com/reference/android/view/View.html#setVerticalScrollBarEnabled%28boolean%29

Seems to be fixed in SupportLibrary 25.1.0 :) Edit: It seems to be fixed, that the state of the selection is saved, when rotating the screen.

found one more way to do it using the boto:

from boto.s3.connection import S3Connection, Bucket, Key

conn = S3Connection(AWS_ACCESS_KEY, AWS_SECERET_KEY)

b = Bucket(conn, S3_BUCKET_NAME)

k = Key(b)

k.key = 'images/my-images/'+filename

b.delete_key(k)

This example made everything clear for me:
As you can see setSoTimeout prevent the program to hang! It wait for SO_TIMEOUT time! if it does not get any signal it throw exception! It means that time expired!

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketTimeoutException;

public class SocketTest extends Thread {
  private ServerSocket serverSocket;

  public SocketTest() throws IOException {
    serverSocket = new ServerSocket(8008);
    serverSocket.setSoTimeout(10000);
  }

  public void run() {
    while (true) {
      try {
        System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "...");
        Socket client = serverSocket.accept();

        System.out.println("Just connected to " + client.getRemoteSocketAddress());
        client.close();
      } catch (SocketTimeoutException s) {
        System.out.println("Socket timed out!");
        break;
      } catch (IOException e) {
        e.printStackTrace();
        break;
      }
    }
  }

  public static void main(String[] args) {
    try {
      Thread t = new SocketTest();
      t.start();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

I like Eclipse + PyDev and/or eric, myself. The new version of PyDev has some pretty awesome code completion support.

Since I only use Eclipse for PyDev, I use a slim install of just the Platform Runtime Binary + PyDev + Subclipse.

jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        print("to_id:", dest.get('id', 'null'))

Try it:

>>> getTargetIds(jsonData)
to_id: 1543
to_id: null

Or, if you just want to skip over values missing ids instead of printing 'null':

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        if 'id' in to_id:
            print("to_id:", dest['id'])

So:

>>> getTargetIds(jsonData)
to_id: 1543

Of course in real life, you probably don't want to print each id, but to store them and do something with them, but that's another issue.

Something like this?

<a href="#" onClick="MyWindow=window.open('http://www.google.com','MyWindow','width=600,height=300'); return false;">Click Here</a>

You can implement this way

$resource('http://localhost\\:3000/realmen/:entryId', {entryId: '@entryId'}, {
        UPDATE: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId' },
        ACTION: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId/action' }
    })

RealMen.query() //GET  /realmen/
RealMen.save({entryId: 1},{post data}) // POST /realmen/1
RealMen.delete({entryId: 1}) //DELETE /realmen/1

//any optional method
RealMen.UPDATE({entryId:1}, {post data}) // PUT /realmen/1

//query string
RealMen.query({name:'john'}) //GET /realmen?name=john

Hope it helps

This is the simplest way I found after using reflector. I created an extension method for that:

public static class ProcessExtensions
{
    public static bool IsRunning(this Process process)
    {
        if (process == null) 
            throw new ArgumentNullException("process");

        try
        {
            Process.GetProcessById(process.Id);
        }
        catch (ArgumentException)
        {
            return false;
        }
        return true;
    }
}

The Process.GetProcessById(processId) method calls the ProcessManager.IsProcessRunning(processId) method and throws ArgumentException in case the process does not exist. For some reason the ProcessManager class is internal...

I agree with Chris Pratt. But I think it's better to create the symlink to original Django folder where the admin templates place in:

ln -s /usr/local/lib/python2.7/dist-packages/django/contrib/admin/templates/admin/ templates/django_admin

and as you can see it depends on python version and the folder where the Django installed. So in future or on a production server you might need to change the path.

arrayList.toArray(new Custom[0]);

Laravel 5 gets its enviroment related variables from the .env file located in the root of your project. You just need to set APP_ENV to whatever you want, for example:

APP_ENV=development

This is used to identify the current enviroment. If you want to display errors, you'll need to enable debug mode in the same file:

APP_DEBUG=true

The role of the .env file is to allow you to have different settings depending on which machine you are running your application. So on your production server, the .env file settings would be different from your local development enviroment.

Documenting in detail for future readers:

The short answer is you need to override both the methods. The shouldOverrideUrlLoading(WebView view, String url) method is deprecated in API 24 and the shouldOverrideUrlLoading(WebView view, WebResourceRequest request) method is added in API 24. If you are targeting older versions of android, you need the former method, and if you are targeting 24 (or later, if someone is reading this in distant future) it's advisable to override the latter method as well.

The below is the skeleton on how you would accomplish this:

class CustomWebViewClient extends WebViewClient {

    @SuppressWarnings("deprecation")
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        final Uri uri = Uri.parse(url);
        return handleUri(uri);
    }

    @TargetApi(Build.VERSION_CODES.N)
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        final Uri uri = request.getUrl();
        return handleUri(uri);
    }

    private boolean handleUri(final Uri uri) {
        Log.i(TAG, "Uri =" + uri);
        final String host = uri.getHost();
        final String scheme = uri.getScheme();
        // Based on some condition you need to determine if you are going to load the url 
        // in your web view itself or in a browser. 
        // You can use `host` or `scheme` or any part of the `uri` to decide.
        if (/* any condition */) {
            // Returning false means that you are going to load this url in the webView itself
            return false;
        } else {
            // Returning true means that you need to handle what to do with the url
            // e.g. open web page in a Browser
            final Intent intent = new Intent(Intent.ACTION_VIEW, uri);
            startActivity(intent);
            return true;
        }
    }
}

Just like shouldOverrideUrlLoading, you can come up with a similar approach for shouldInterceptRequest method.

Since PHP 5.4 you can use:

htmlspecialchars($string, ENT_XML1);

You should specify the encoding, such as:

htmlspecialchars($string, ENT_XML1, 'UTF-8');

Update

Note that the above will only convert:

• & to &
• < to <
• > to >

If you want to escape text for use in an attribute enclosed in double quotes:

htmlspecialchars($string, ENT_XML1 | ENT_COMPAT, 'UTF-8');

will convert " to " in addition to &, < and >.

And if your attributes are enclosed in single quotes:

htmlspecialchars($string, ENT_XML1 | ENT_QUOTES, 'UTF-8');

will convert ' to ' in addition to &, <, > and ".

(Of course you can use this even outside of attributes).

See the manual entry for htmlspecialchars.

Try what's below. It will help you...

Fiddle : http://jsfiddle.net/RYh7U/146/

Script :

if(dateCheck("02/05/2013","02/09/2013","02/07/2013"))
    alert("Availed");
else
    alert("Not Availed");

function dateCheck(from,to,check) {

    var fDate,lDate,cDate;
    fDate = Date.parse(from);
    lDate = Date.parse(to);
    cDate = Date.parse(check);

    if((cDate <= lDate && cDate >= fDate)) {
        return true;
    }
    return false;
}

Let's take advantage of new Function. Thus i stops to be a variable of a closure and becomes just a part of the text:

var funcs = [];
for (var i = 0; i < 3; i++) {
    var functionBody = 'console.log("My value: ' + i + '");';
    funcs[i] = new Function(functionBody);
}

for (var j = 0; j < 3; j++) {
    funcs[j]();
}

run(s) of digits

This answer works with any count of digit groups. Example:

$ echo 'Num123that456are7899900contained0018166intext' \
   | sed -En 's/[^0-9]*([0-9]{1,})[^0-9]*/\1 /gp'

123 456 7899900 0018166

Expanded answer.

Is there any way to tell sed to output only captured groups?

Yes. replace all text by the capture group:

$ echo 'Number 123 inside text' \
   | sed 's/[^0-9]*\([0-9]\{1,\}\)[^0-9]*/\1/'

123

s/[^0-9]*                           # several non-digits
         \([0-9]\{1,\}\)            # followed by one or more digits
                        [^0-9]*     # and followed by more non-digits.
                               /\1/ # gets replaced only by the digits.

Or with extended syntax (less backquotes and allow the use of +):

$ echo 'Number 123 in text' \
   | sed -E 's/[^0-9]*([0-9]+)[^0-9]*/\1/'

123

To avoid printing the original text when there is no number, use:

$ echo 'Number xxx in text' \
   | sed -En 's/[^0-9]*([0-9]+)[^0-9]*/\1/p'

• (-n) Do not print the input by default.
• (/p) print only if a replacement was done.

And to match several numbers (and also print them):

$ echo 'N 123 in 456 text' \
  | sed -En 's/[^0-9]*([0-9]+)[^0-9]*/\1 /gp'

123 456

That works for any count of digit runs:

$ str='Test Num(s) 123 456 7899900 contained as0018166df in text'
$ echo "$str" \
   | sed -En 's/[^0-9]*([0-9]{1,})[^0-9]*/\1 /gp'

123 456 7899900 0018166

Which is very similar to the grep command:

$ str='Test Num(s) 123 456 7899900 contained as0018166df in text'
$ echo "$str" | grep -Po '\d+'
123
456
7899900
0018166

About \d

and pattern: /([\d]+)/

Sed does not recognize the '\d' (shortcut) syntax. The ascii equivalent used above [0-9] is not exactly equivalent. The only alternative solution is to use a character class: '[[:digit:]]`.

The selected answer use such "character classes" to build a solution:

$ str='This is a sample 123 text and some 987 numbers'
$ echo "$str" | sed -rn 's/[^[:digit:]]*([[:digit:]]+)[^[:digit:]]+([[:digit:]]+)[^[:digit:]]*/\1 \2/p'

That solution only works for (exactly) two runs of digits.

Of course, as the answer is being executed inside the shell, we can define a couple of variables to make such answer shorter:

$ str='This is a sample 123 text and some 987 numbers'
$ d=[[:digit:]]     D=[^[:digit:]]
$ echo "$str" | sed -rn "s/$D*($d+)$D+($d+)$D*/\1 \2/p"

But, as has been already explained, using a s/…/…/gp command is better:

$ str='This is 75577 a sam33ple 123 text and some 987 numbers'
$ d=[[:digit:]]     D=[^[:digit:]]
$ echo "$str" | sed -rn "s/$D*($d+)$D*/\1 /gp"
75577 33 123 987

That will cover both repeated runs of digits and writing a short(er) command.

I also used @Ori Drori's answer and managed to get it to work. As your React code grows, so will the bundles compiled that the client browser will have to download on first time access. This imposes a user experience issue if you don't handle it well.

What I added to @Ori answer was to add and execute the onload function in the index.html on onload attribute of the body tag, so that the loader disappear after everything has been fully loaded in the browse, see the snippet below:

<html>
  <head>
     <style>
       .loader:empty {
          position: absolute;
          top: calc(50% - 4em);
          left: calc(50% - 4em);
          width: 6em;
          height: 6em;
          border: 1.1em solid rgba(0, 0, 0, 0.2);
          border-left: 1.1em solid #000000;
          border-radius: 50%;
          animation: load8 1.1s infinite linear;
        }
        @keyframes load8 {
          0% {
           transform: rotate(0deg);
          }
          100% {
           transform: rotate(360deg);
          }
        }
     </style>
     <script>
       function onLoad() {
         var loader = document.getElementById("cpay_loader");loader.className = "";}
     </script>
   </head>
   <body onload="onLoad();">
     more html here.....
   </body>
</html>

Here's the exact definition of UsedRange (MSDN reference) :

Every Worksheet object has a UsedRange property that returns a Range object representing the area of a worksheet that is being used. The UsedRange property represents the area described by the farthest upper-left and farthest lower-right nonempty cells in a worksheet and includes all cells in between.

So basically, what that line does is :

1. .UsedRange -> "Draws" a box around the outer-most cells with content inside.
2. .Columns -> Selects the entire columns of those cells
3. .Count -> Returns an integer corresponding to how many columns there are (in this selection)
4. - 8 -> Subtracts 8 from the previous integer.

I assume VBA calculates the UsedRange by finding the non-empty cells with lowest and highest index values.

Most likely, you're getting an error because the number of lines in your range is smaller than 3, and therefore the number returned is negative.

I would just like to throw the idea of annotation : @getter and @setter. With @getter, you should be able to obj = class.field but not class.field = obj. With @setter, vice versa. With @getter and @setter you should be able to do both. This would preserve encapsulation and reduce the time by not calling trivial methods at runtime.

Per https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding and http://en.wikipedia.org/wiki/Basic_access_authentication , here is how to do Basic auth with a header instead of putting the username and password in the URL. Note that this still doesn't hide the username or password from anyone with access to the network or this JS code (e.g. a user executing it in a browser):

$.ajax({
  type: 'POST',
  url: http://theappurl.com/api/v1/method/,
  data: {},
  crossDomain: true,
  beforeSend: function(xhr) {
    xhr.setRequestHeader('Authorization', 'Basic ' + btoa(unescape(encodeURIComponent(YOUR_USERNAME + ':' + YOUR_PASSWORD))))
  }
});

Following the example of the Andrzej Doyle's answer, I think the better solution is to use org.apache.commons.lang3.StringUtils.stripAccents():

package bla.bla.utility;

import org.apache.commons.lang3.StringUtils;

public class UriUtility {
    public static String normalizeUri(String s) {
        String r = StringUtils.stripAccents(s);
        r = r.replace(" ", "_");
        r = r.replaceAll("[^\\.A-Za-z0-9_]", "");
        return r;
    }
}

Try something like:

$post_data="dispnumber=567567567&extension=6";
$url="http://xxxxxxxx.xxx/xx/xx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch);

echo $result;

Need to set the foreign key option as on delete cascade... in tables which contains foreign key columns.... It need to set at the time of table creation or add later using ALTER table

I would choose the second as you don't have to do a copy of the memory and the Iterator works faster. So you save memory and time.

You can declare the array in C++ in these type of ways. If you know the array size then you should declare the array for: integer: int myArray[array_size]; Double: double myArray[array_size]; Char and string : char myStringArray[array_size]; The difference between char and string is as follows

char myCharArray[6]={'a','b','c','d','e','f'};
char myStringArray[6]="abcdef";

If you don't know the size of array then you should leave the array blank like following.

integer: int myArray[array_size];

Double: double myArray[array_size];

try this

counter = 0

def increment():
  global counter
  counter += 1

increment()

Checkout this, This is from PHP MANUAL, This may help you.

If you're using PHP_CLI SAPI and getting error "Maximum execution time of N seconds exceeded" where N is an integer value, try to call set_time_limit(0) every M seconds or every iteration. For example:

<?php

require_once('db.php');

$stmt = $db->query($sql);

while ($row = $stmt->fetchRow()) {
    set_time_limit(0);
    // your code here
}

?>

Yes there is retainAll check out this

Set<Type> intersection = new HashSet<Type>(s1);
intersection.retainAll(s2);

You can use the split() function, which returns a list, to separate them.

letters = 'QH QD JC KD JS'

letters_list = letters.split()

Printing letters_list would now format it like this:

['QH', 'QD', 'JC', 'KD', 'JS']

Now you have a list that you can work with, just like you would with any other list. For example accessing elements based on indexes:

print(letters_list[2])

This would print the third element of your list, which is 'JC'

package newpckg;

import java.util.Date;
import java.text.ParseException;
import java.text.SimpleDateFormat;

public class StrangeDate {

    public static void main(String[] args) {

        // string containing date in one format
        // String strDate = "2012-05-20T09:00:00.000Z";
        String strDate = "2012-05-20T09:00:00.000Z";

        try {
            // create SimpleDateFormat object with source string date format
            SimpleDateFormat sdfSource = new SimpleDateFormat(
                    "yyyy-MM-dd'T'hh:mm:ss'.000Z'");

            // parse the string into Date object
            Date date = sdfSource.parse(strDate);

            // create SimpleDateFormat object with desired date format
            SimpleDateFormat sdfDestination = new SimpleDateFormat(
                    "dd/MM/yyyy, ha");

            // parse the date into another format
            strDate = sdfDestination.format(date);

            System.out
                    .println("Date is converted from yyyy-MM-dd'T'hh:mm:ss'.000Z' format to dd/MM/yyyy, ha");
            System.out.println("Converted date is : " + strDate.toLowerCase());

        } catch (ParseException pe) {
            System.out.println("Parse Exception : " + pe);
        }
    }
}

If you want to access your page's global variables, you can do so:

@{
    ViewData["Title"] = "Home Page";

    var LoadingButtons = Model.ToDictionary(person => person, person => false);

    string GetLoadingState (string person) => LoadingButtons[person] ? "is-loading" : string.Empty;
}

I have tried like this .Please review and update me whether it is right approach or not.

#/bin/sh
function pause(){
   read -p "$*"
}

file="./apptest.properties"


if [ -f "$file" ]
then
    echo "$file found."

dbUser=`sed '/^\#/d' $file | grep 'db.uat.user'  | tail -n 1 | cut -d "=" -f2- | sed 's/^[[:space:]]*//;s/[[:space:]]*$//'`
dbPass=`sed '/^\#/d' $file | grep 'db.uat.passwd'  | tail -n 1 | cut -d "=" -f2- | sed 's/^[[:space:]]*//;s/[[:space:]]*$//'`

echo database user = $dbUser
echo database pass = $dbPass

else
    echo "$file not found."
fi

Ultimately, the filter that is displayed in the Browse window is set by the browser. You can specify all of the filters you want in the Accept attribute, but you have no guarantee that your user's browser will adhere to it.

Your best bet is to do some kind of filtering in the back end on the server.

All you need is a <clear /> tag. Here's an example:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

I got really tired of going through answers only to find it did not work as expected.

Solution

Make a vbs script to run a hidden batch file which launches the powershell script. Seems silly to make 3 files for this task but atleast the total size is less than 2KB and it runs perfect from tasker or manually (you dont see anything).

scriptName.vbs

Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Users\leathan\Documents\scriptName.bat" & Chr(34), 0
Set WinScriptHost = Nothing

scriptName.bat

powershell.exe -ExecutionPolicy Bypass C:\Users\leathan\Documents\scriptName.ps1

scriptName.ps1

Your magical code here.

It seems that you have forgotten to add your state server address in the config file.

 <sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />

I found that @Column(columnDefinition="serial") works perfect but only for PostgreSQL. For me this was perfect solution, because second entity is "ugly" option.

A call to saveAndFlush on the entity is also necessary, and save won't be enough to populate the value from the DB.

Great article i found what worked best for me was to add a % to the size

.wrap {
margin-top:5%;
margin-bottom:5%;
height:100%;
display:block;}

Use ClassLoader#getResource() instead if its URI represents a valid local disk file system path.

URL resource = classLoader.getResource("resource.ext");
File file = new File(resource.toURI());
FileInputStream input = new FileInputStream(file);
// ...

If it doesn't (e.g. JAR), then your best bet is to copy it into a temporary file.

Path temp = Files.createTempFile("resource-", ".ext");
Files.copy(classLoader.getResourceAsStream("resource.ext"), temp, StandardCopyOption.REPLACE_EXISTING);
FileInputStream input = new FileInputStream(temp.toFile());
// ...

That said, I really don't see any benefit of doing so, or it must be required by a poor helper class/method which requires FileInputStream instead of InputStream. If you can, just fix the API to ask for an InputStream instead. If it's a 3rd party one, by all means report it as a bug. I'd in this specific case also put question marks around the remainder of that API.

Something like the standard Collection.toArray(T[]) should do what you need (note that ArrayList implements Collection):

TypeA[] array = a.toArray(new TypeA[a.size()]);

On a side note, you should consider defining a to be of type List<TypeA> rather than ArrayList<TypeA>, this avoid some implementation specific definition that may not really be applicable for your application.

Also, please see this question about the use of a.size() instead of 0 as the size of the array passed to a.toArray(TypeA[])

If you are developing for Windows, the com0com project might be, what you are looking for.

It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one.

EDIT:

As Thomas pointed out the project lacks of a signed driver, which is especially problematic on certain Windows version (e.g. Windows 7 x64).

There are a couple of unofficial com0com versions around that do contain a signed driver. One recent verion (3.0.0.0) can be downloaded e.g. from here.

If you are on .NET 4.0 use a Tuple:

lookup = new Dictionary<Tuple<TypeA, TypeB, TypeC>, string>();

If not you can define a Tuple and use that as the key. The Tuple needs to override GetHashCode, Equals and IEquatable:

struct Tuple<T, U, W> : IEquatable<Tuple<T,U,W>>
{
    readonly T first;
    readonly U second;
    readonly W third;

    public Tuple(T first, U second, W third)
    {
        this.first = first;
        this.second = second;
        this.third = third;
    }

    public T First { get { return first; } }
    public U Second { get { return second; } }
    public W Third { get { return third; } }

    public override int GetHashCode()
    {
        return first.GetHashCode() ^ second.GetHashCode() ^ third.GetHashCode();
    }

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
        {
            return false;
        }
        return Equals((Tuple<T, U, W>)obj);
    }

    public bool Equals(Tuple<T, U, W> other)
    {
        return other.first.Equals(first) && other.second.Equals(second) && other.third.Equals(third);
    }
}

This did the trick for me

You need to use overflow option like below:

.nav{
    max-height: 300px;
    overflow-y: scroll; 
}

Change the height according to amount of items you need to show

WARNING: There are reports that this will not work on iOS 6. This might only work on older versions of the OS. Evidently at least one dev has had their app rejected for using this trick (see the comments). Use at your own risk. Using an image (see answer above) might be a safer solution.

This can be done without adding in your own image files using sekr1t button type 101 to get the correct shape. For me the trick was figuring out that I could use initWithCustomView to create the BarButtonItem. I personally needed this for a dynamic navbar rather than a toolbar, but I tested it with a toolbar and the code is nearly the same:

// create button
UIButton* backButton = [UIButton buttonWithType:101]; // left-pointing shape!
[backButton addTarget:self action:@selector(backAction) forControlEvents:UIControlEventTouchUpInside];
[backButton setTitle:@"Back" forState:UIControlStateNormal];

// create button item -- possible because UIButton subclasses UIView!
UIBarButtonItem* backItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];

// add to toolbar, or to a navbar (you should only have one of these!)
[toolbar setItems:[NSArray arrayWithObject:backItem]];
navItem.leftBarButtonItem = backItem;

If you're doing this on a toolbar you'll have to tweak how you set the items, but that depends on the rest of your code and I leave that as an exercise for the reader. :P This sample worked for me (compiled & run).

Blah blah, read the HIG, don't use undocumented features, and all that. There's only six supported button types and this isn't one of them.

In Python 3, raw_input() doesn't exist which was already mentioned by Sven.

In Python 2, the input() function evaluates your input.

Example:

name = input("what is your name ?")
what is your name ?harsha

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    name = input("what is your name ?")
  File "<string>", line 1, in <module>
NameError: name 'harsha' is not defined

In the example above, Python 2.x is trying to evaluate harsha as a variable rather than a string. To avoid that, we can use double quotes around our input like "harsha":

>>> name = input("what is your name?")
what is your name?"harsha"
>>> print(name)
harsha

raw_input()

The raw_input()` function doesn't evaluate, it will just read whatever you enter.

Example:

name = raw_input("what is your name ?")
what is your name ?harsha
>>> name
'harsha'

Example:

 name = eval(raw_input("what is your name?"))
what is your name?harsha

Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    name = eval(raw_input("what is your name?"))
  File "<string>", line 1, in <module>
NameError: name 'harsha' is not defined

In example above, I was just trying to evaluate the user input with the eval function.

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

With:

Calendar cal = Calendar.getInstance();

Then cal have the current date and time.
You also could get the current Date and Time for timezone with:

Calendar cal2 = Calendar.getInstance(TimeZone.getTimeZone("GMT-2"));

You could ask cal.get(Calendar.DATE); or other Calendar constant about others details.
Date and Timestamp are deprecated in Java. Calendar class it isn't.

Swift Solution

Follow these steps:

1. Set the height constraint for the table from the storyboard.

2. Drag the height constraint from the storyboard and create @IBOutlet for it in the view controller file.

   @IBOutlet var tableHeight: NSLayoutConstraint!
   

3. Then you can change the height for the table dynamicaly using this code:

   override func viewWillLayoutSubviews() {
       super.updateViewConstraints()
       self.tableHeight?.constant = self.table.contentSize.height
   }
   

If the last row is cut off, try to call viewWillLayoutSubviews() in willDisplay cell function:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    self.viewWillLayoutSubviews()
}

One needs to understand what a JOIN or a series of JOINs does to a set of data. With strae's post, a pe_id of 1 joined with corresponding order and items on pe_id = 1 will give you the following data to "select" from:

[ table people portion ] [ table orders portion ] [ table items portion ]

| people.pe_id | people.pe_name | orders.ord_id | orders.pe_id | orders.ord_title | item.item_id | item.ord_id | item.pe_id | item.title |

| 1 | Foo | 1 | 1 | First order | 1 | 1 | 1 | Apple |
| 1 | Foo | 1 | 1 | First order | 2 | 1 | 1 | Pear |

The joins essentially come up with a cartesian product of all the tables. You basically have that data set to select from and that's why you need a distinct count on orders.ord_id and items.item_id. Otherwise both counts will result in 2 - because you effectively have 2 rows to select from.

NetBeans 7 has nice support for HTML5. Previously I was a heavy user of Eclipse, but spend more time with NetBeans to play with HTML5 and Servlet.

To pass the source element in Angular 5 :

<input #myInput type="text" (change)="someFunction(myInput)">

Yes, it's doable due to jQuery's noconflict mode. http://blog.nemikor.com/2009/10/03/using-multiple-versions-of-jquery/

<!-- load jQuery 1.1.3 -->
<script type="text/javascript" src="http://example.com/jquery-1.1.3.js"></script>
<script type="text/javascript">
var jQuery_1_1_3 = $.noConflict(true);
</script>

<!-- load jQuery 1.3.2 -->
<script type="text/javascript" src="http://example.com/jquery-1.3.2.js"></script>
<script type="text/javascript">
var jQuery_1_3_2 = $.noConflict(true);
</script>

Then, instead of $('#selector').function();, you'd do jQuery_1_3_2('#selector').function(); or jQuery_1_1_3('#selector').function();.

If you are using autolayout, set the vertical contentHuggingPriority to 1000, either in code or IB. In IB you may then have to remove a height constraint by setting it's priority to 1 and then deleting it.

Here is an easy solution.. I messed with this for awhile. I should point out, this is a specific set of instructions using Android Studio and the AVD Emulator.

1) Start the Emulator and run your app.

2) While the app is still running, open the Android Device Monitor. (its in the toolbar next to the AVD and SDK manager icons)

3) Click the File Explorer tab in the Device Monitor. There should be a lot of folders.

4) Navigate the following path: Data > Data > Your Package Name > files > Default.Realm (or whatever you named it)

Ex. If you are using one of the realm example projects, the path would be something like Data>Data>io.realm.examples.realmgridview>files>default.realm

5) Highlight the file, click the Floppy Disk icon in the upper right area "pull a file from the device"

6) Save it off to whereever you want and done.

I have also faced similar issue try this hope it helps someone As I'm using windows so followed the steps as given below Open command prompt as an administrator and then go to this path

C:\Users\%username%\AppData\Roaming\npm\

Look for the file ng.ps1 in this folder (dir) and then delete it (del ng.ps1)

You can also clear npm cache after this though it should work without this step as well. Hope it helps as it worked for me.

This way you can execute an action when all images inside body or any other container (that depends of your selection) are loaded. PURE JQUERY, no pluggins needed.

var counter = 0;
var size = $('img').length;

$("img").load(function() { // many or just one image(w) inside body or any other container
    counter += 1;
    counter === size && $('body').css('background-color', '#fffaaa'); // any action
}).each(function() {
  this.complete && $(this).load();        
});

How about:

using (ModelName context = new ModelName())
{
    var ptx = (from r in context.TableName select r);
}

ModelName is the class auto-generated by the designer, which inherits from ObjectContext.

You can set the row height by code

dataGridView.RowTemplate.Height = 35;

or by property panel

try something like

background: url(bgimage.jpg) no-repeat;
background-size: 100%;

You should never add credentials to a container unless you're OK broadcasting the creds to whomever can download the image. In particular, doing and ADD creds and later RUN rm creds is not secure because the creds file remains in the final image in an intermediate filesystem layer. It's easy for anyone with access to the image to extract it.

The typical solution I've seen when you need creds to checkout dependencies and such is to use one container to build another. I.e., typically you have some build environment in your base container and you need to invoke that to build your app container. So the simple solution is to add your app source and then RUN the build commands. This is insecure if you need creds in that RUN. Instead what you do is put your source into a local directory, run (as in docker run) the container to perform the build step with the local source directory mounted as volume and the creds either injected or mounted as another volume. Once the build step is complete you build your final container by simply ADDing the local source directory which now contains the built artifacts.

I'm hoping Docker adds some features to simplify all this!

Update: looks like the method going forward will be to have nested builds. In short, the dockerfile would describe a first container that is used to build the run-time environment and then a second nested container build that can assemble all the pieces into the final container. This way the build-time stuff isn't in the second container. This of a Java app where you need the JDK for building the app but only the JRE for running it. There are a number of proposals being discussed, best to start from https://github.com/docker/docker/issues/7115 and follow some of the links for alternate proposals.

What is the difference between the list methods append and extend?

• append adds its argument as a single element to the end of a list. The length of the list itself will increase by one.
• extend iterates over its argument adding each element to the list, extending the list. The length of the list will increase by however many elements were in the iterable argument.

append

The list.append method appends an object to the end of the list.

my_list.append(object) 

Whatever the object is, whether a number, a string, another list, or something else, it gets added onto the end of my_list as a single entry on the list.

>>> my_list
['foo', 'bar']
>>> my_list.append('baz')
>>> my_list
['foo', 'bar', 'baz']

So keep in mind that a list is an object. If you append another list onto a list, the first list will be a single object at the end of the list (which may not be what you want):

>>> another_list = [1, 2, 3]
>>> my_list.append(another_list)
>>> my_list
['foo', 'bar', 'baz', [1, 2, 3]]
                     #^^^^^^^^^--- single item at the end of the list.

extend

The list.extend method extends a list by appending elements from an iterable:

my_list.extend(iterable)

So with extend, each element of the iterable gets appended onto the list. For example:

>>> my_list
['foo', 'bar']
>>> another_list = [1, 2, 3]
>>> my_list.extend(another_list)
>>> my_list
['foo', 'bar', 1, 2, 3]

Keep in mind that a string is an iterable, so if you extend a list with a string, you'll append each character as you iterate over the string (which may not be what you want):

>>> my_list.extend('baz')
>>> my_list
['foo', 'bar', 1, 2, 3, 'b', 'a', 'z']

Operator Overload, __add__ (+) and __iadd__ (+=)

Both + and += operators are defined for list. They are semantically similar to extend.

my_list + another_list creates a third list in memory, so you can return the result of it, but it requires that the second iterable be a list.

my_list += another_list modifies the list in-place (it is the in-place operator, and lists are mutable objects, as we've seen) so it does not create a new list. It also works like extend, in that the second iterable can be any kind of iterable.

Don't get confused - my_list = my_list + another_list is not equivalent to += - it gives you a brand new list assigned to my_list.

Time Complexity

Append has constant time complexity, O(1).

Extend has time complexity, O(k).

Iterating through the multiple calls to append adds to the complexity, making it equivalent to that of extend, and since extend's iteration is implemented in C, it will always be faster if you intend to append successive items from an iterable onto a list.

Performance

You may wonder what is more performant, since append can be used to achieve the same outcome as extend. The following functions do the same thing:

def append(alist, iterable):
    for item in iterable:
        alist.append(item)

def extend(alist, iterable):
    alist.extend(iterable)

So let's time them:

import timeit

>>> min(timeit.repeat(lambda: append([], "abcdefghijklmnopqrstuvwxyz")))
2.867846965789795
>>> min(timeit.repeat(lambda: extend([], "abcdefghijklmnopqrstuvwxyz")))
0.8060121536254883

Addressing a comment on timings

A commenter said:

Perfect answer, I just miss the timing of comparing adding only one element

Do the semantically correct thing. If you want to append all elements in an iterable, use extend. If you're just adding one element, use append.

Ok, so let's create an experiment to see how this works out in time:

def append_one(a_list, element):
    a_list.append(element)

def extend_one(a_list, element):
    """creating a new list is semantically the most direct
    way to create an iterable to give to extend"""
    a_list.extend([element])

import timeit

And we see that going out of our way to create an iterable just to use extend is a (minor) waste of time:

>>> min(timeit.repeat(lambda: append_one([], 0)))
0.2082819009956438
>>> min(timeit.repeat(lambda: extend_one([], 0)))
0.2397019260097295

We learn from this that there's nothing gained from using extend when we have only one element to append.

Also, these timings are not that important. I am just showing them to make the point that, in Python, doing the semantically correct thing is doing things the Right Way™.

It's conceivable that you might test timings on two comparable operations and get an ambiguous or inverse result. Just focus on doing the semantically correct thing.

Conclusion

We see that extend is semantically clearer, and that it can run much faster than append, when you intend to append each element in an iterable to a list.

If you only have a single element (not in an iterable) to add to the list, use append.

String is immutable and it goes to the string pool. Once written, it cannot be overwritten.

char[] is an array which you should overwrite once you used the password and this is how it should be done:

char[] passw = request.getPassword().toCharArray()
if (comparePasswords(dbPassword, passw) {
 allowUser = true;
 cleanPassword(passw);
 cleanPassword(dbPassword);
 passw=null;
}

private static void cleanPassword (char[] pass) {

Arrays.fill(pass, '0');
}

One scenario where the attacker could use it is a crashdump - when the JVM crashes and generates a memory dump - you will be able to see the password.

That is not necessarily a malicious external attacker. This could be a support user that has access to the server for monitoring purposes. He could peek into a crashdump and find the passwords.

Easiest way to blanket remove a character from string is to Trim it

cl = cl.Trim(' ');

Removes all of the spaces in a string

Use the global flag:

var name = name.replace(/[^a-zA-Z ]/g, "");
                                    ^

If you don't want to remove numbers, add it to the class:

var name = name.replace(/[^a-zA-Z0-9 ]/g, "");

If your attachments are

@attachments = Job.find(1).attachments

This will be array of attachment objects

Use select method to filter based on file_type.

@logos = @attachments.select { |attachment| attachment.file_type == 'logo' }
@images = @attachments.select { |attachment| attachment.file_type == 'image' }

This will not trigger any db query.

Databases are isolated in PostgreSQL; when you connect to a PostgreSQL server you connect to just one database, you can't copy data from one database to another using a SQL query.

If you come from MySQL: what MySQL calls (loosely) "databases" are "schemas" in PostgreSQL - sort of namespaces. A PostgreSQL database can have many schemas, each one with its tables and views, and you can copy from one schema to another with the schema.table syntax.

If you really have two distinct PostgreSQL databases, the common way of transferring data from one to another would be to export your tables (with pg_dump -t ) to a file, and import them into the other database (with psql).

If you really need to get data from a distinct PostgreSQL database, another option - mentioned in Grant Johnson's answer - is dblink, which is an additional module (in contrib/).

Update:

Postgres introduced "foreign data wrapper" in 9.1 (which was released after the question was asked). Foreign data wrappers allow the creation of foreign tables through the Postgres FDW which makes it possible to access a remote table (on a different server and database) as if it was a local table.

Maybe you're not using the latest version of a JSON for Java Library.

json-simple has not been updated for a long time, while JSON-Java was updated 2 month ago.

JSON-Java can be found on GitHub, here is the link to its repo: https://github.com/douglascrockford/JSON-java

After switching the library, you can refer to my sample code down below:

public static void main(String[] args) {
    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";

    JSONObject jsonObject = new JSONObject(JSON);
    JSONObject getSth = jsonObject.getJSONObject("LanguageLevels");
    Object level = getSth.get("2");

    System.out.println(level);
}

And as JSON-Java open-sourced, you can read the code and its document, they will guide you through.

Hope that it helps.

I am surprised that there's no concise answer yet, although such an expand/collapse animation is very easy to achieve with just 2 lines of code:

together with

Like this:

void * p = (void *)0x28ff44;

Or if you want it as a char *:

char * p = (char *)0x28ff44;

...etc.

If you're pointing to something you really, really aren't meant to change, add a const:

const void * p = (const void *)0x28ff44;
const char * p = (const char *)0x28ff44;

...since I figure this must be some kind of "well-known address" and those are typically (though by no means always) read-only.

Additionally, DataContractSerializer will serialize items marked as [Serializable] and will also serialize unmarked types in .NET 3.5 SP1 and later, to allow support for serializing anonymous types.

So, it depends on how you've decorated your class as to how to keep a member from serializing:

• If you used [DataContract], then remove the [DataMember] for the property.
• If you used [Serializable], then add [NonSerialized] in front of the field for the property.
• If you haven't decorated your class, then you should add [IgnoreDataMember] to the property.

FILE *f = fopen("file.txt", "r");

If its just about detecting whether or not you're dealing with an Object, I could think of

Object.getPrototypeOf( obj ) === Object.prototype

However, this would probably fail for non-object primitive values. Actually there is nothing wrong with invoking .toString() to retreive the [[cclass]] property. You can even create a nice syntax like

var type = Function.prototype.call.bind( Object.prototype.toString );

and then use it like

if( type( obj ) === '[object Object]' ) { }

It might not be the fastest operation but I don't think the performance leak there is too big.

There is a pull request here. But you can simply do train, test = next(iter(StratifiedKFold(...))) and use the train and test indices if you want.

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

Instead using border use box-shadow:

  box-shadow: 
    2px 0 0 0 #888, 
    0 2px 0 0 #888, 
    2px 2px 0 0 #888,   /* Just to fix the corner */
    2px 0 0 0 #888 inset, 
    0 2px 0 0 #888 inset;

A silly hack I did was to set the height of the element to zero but overflow:visible; combining this with pointer-events:none; seems to cover all the bases.

.overlay {
    height:0px;
    overflow:visible;
    pointer-events:none;
    background:none !important;
}

I would do this slightly different by applying both the UNPIVOT and the PIVOT functions to get the final result. The unpivot takes the values from both the totalcount and totalamount columns and places them into one column with multiple rows. You can then pivot on those results.:

select chardate,
  Australia_totalcount as [Australia # of Transactions], 
  Australia_totalamount as [Australia Total $ Amount],
  Austria_totalcount as [Austria # of Transactions], 
  Austria_totalamount as [Austria Total $ Amount]
from
(
  select 
    numericmonth, 
    chardate,
    country +'_'+col col, 
    value
  from
  (
    select numericmonth, 
      country, 
      chardate,
      cast(totalcount as numeric(10, 2)) totalcount,
      cast(totalamount as numeric(10, 2)) totalamount
    from mytransactions
  ) src
  unpivot
  (
    value
    for col in (totalcount, totalamount)
  ) unpiv
) s
pivot
(
  sum(value)
  for col in (Australia_totalcount, Australia_totalamount,
              Austria_totalcount, Austria_totalamount)
) piv
order by numericmonth

If you have an unknown number of country names, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @colsName AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(country +'_'+c.col) 
                      from mytransactions
                      cross apply 
                      (
                        select 'TotalCount' col
                        union all
                        select 'TotalAmount'
                      ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @colsName 
    = STUFF((SELECT distinct ', ' + QUOTENAME(country +'_'+c.col) 
               +' as ['
               + country + case when c.col = 'TotalCount' then ' # of Transactions]' else 'Total $ Amount]' end
             from mytransactions
             cross apply 
             (
                select 'TotalCount' col
                union all
                select 'TotalAmount'
             ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query 
  = 'SELECT chardate, ' + @colsName + ' 
     from 
     (
      select 
        numericmonth, 
        chardate,
        country +''_''+col col,

     pivot 
     (

       for col in (' + @cols + ')
     ) p 
     order by numericmonth'

execute(@query)

New line depends on your OS:

DOS & Windows: \r\n 0D0A (hex), 13,10 (decimal)
Unix & Mac OS X: \n, 0A, 10
Macintosh (OS 9): \r, 0D, 13

More details here: https://ccrma.stanford.edu/~craig/utility/flip/

When in doubt, use any freeware hex viewer/editor to see how a file encodes its new line.

For me, I use following guide to help me remember: 0D0A = \r\n = CR,LF = carriage return, line feed

I do tend to use static classes for factories. For example, this is the logging class in one of my projects:

public static class Log
{
   private static readonly ILoggerFactory _loggerFactory =
      IoC.Resolve<ILoggerFactory>();

   public static ILogger For<T>(T instance)
   {
      return For(typeof(T));
   }

   public static ILogger For(Type type)
   {
      return _loggerFactory.GetLoggerFor(type);
   }
}

You might have even noticed that IoC is called with a static accessor. Most of the time for me, if you can call static methods on a class, that's all you can do so I mark the class as static for extra clarity.

And remember to use parenthesis!

Keep in mind that & operator takes a precedence over operators such as > or < etc. That is why

4 < 5 & 6 > 4

evaluates to False. Therefore if you're using pd.loc, you need to put brackets around your logical statements, otherwise you get an error. That's why do:

df.loc[(df['A'] > 10) & (df['B'] < 15)]

instead of

df.loc[df['A'] > 10 & df['B'] < 15]

which would result in

TypeError: cannot compare a dtyped [float64] array with a scalar of type [bool]

For me, removing WebDAV from my server caused the application to return a 503 Service Unavailable Error message when using PUT or DELETE, so I re-installed it back again. I also tried completely removing .NET Framework 4.5 and reinstalling it and also tried re-registering as suggested but to no avail.

I was able to fix this by disabling WebDAV for the individual application pool, this stopped the 'bad module' error when using PUT or DELETE.

Disable WebDAV for Individual App Pool:

1. Click the affected application pool
2. Find WebDAV Authoring Tools in the list
3. Click to open it
4. Click Disable WebDAV in the top right.

Ta daaaa!

I still left the remove items in my web.config file.

 <system.webServer>
    <modules>
      <remove name="WebDAVModule"/>
    </modules>
    <handlers>
      <remove name="WebDAV" />
    </handlers>
 <system.webServer>

This link is where I found the instructions but it's not very clear.

Change the code to:

public abstract class clsAbstractTable {
  protected String TAG;
  public abstract void init();
}

public class clsContactGroups extends clsAbstractTable {
  public String doSomething() {
    return TAG + "<something else>";
  }
}

That way, all of the classes who inherit this class will have this variable. You can do 200 subclasses and still each one of them will have this variable.

Side note: do not use CAPS as variable name; common wisdom is that all caps identifiers refer to constants, i.e. non-changeable pieces of data.

It looks like someone might have revoked the permissions on sys.configurations for the public role. Or denied access to this view to this particular user. Or the user has been created after the public role was removed from the sys.configurations tables.

When using Jest 21.2.1, I can see code coverage at the command line and create a coverage directory by passing --coverage to the Jest script. Below are some examples:

I tend to install Jest locally, in which case the command might look like this:

npx jest --coverage

I assume (though haven't confirmed), that this would also work if I installed Jest globally:

jest --coverage

The very sparse docs are here

When I navigated into the coverage/lcov-report directory I found an index.html file that could be loaded into a browser. It included the information printed at the command line, plus additional information and some graphical output.

import urllib
resource = urllib.urlopen("http://www.digimouth.com/news/media/2011/09/google-logo.jpg")
output = open("file01.jpg","wb")
output.write(resource.read())
output.close()

file01.jpg will contain your image.

Either your data is bad, or it's not structured the way you think it is. Possibly both.

To prove/disprove this hypothesis, run this query:

SELECT * from
(
    SELECT count(*) as c, Supplier_Item.SKU
    FROM Supplier_Item
    INNER JOIN orderdetails
        ON Supplier_Item.sku = orderdetails.sku
    INNER JOIN Supplier
        ON Supplier_item.supplierID = Supplier.SupplierID
    GROUP BY Supplier_Item.SKU
) x
WHERE c > 1
ORDER BY c DESC

If this returns just a few rows, then your data is bad. If it returns lots of rows, then your data is not structured the way you think it is. (If it returns zero rows, I'm wrong.)

I'm guessing that you have orders containing the same SKU multiple times (two separate line items, both ordering the same SKU).

I use these lines in .htaccess file; which I place in root folder

RewriteEngine on

RewriteRule ^(.*)$ index.php/$1 [QSA,L]

I think one should use singleton pattern to avoid having to create instances of the HttpClient and closing it all the time. If you are using .Net 4.0 you could use a sample code as below. for more information on singleton pattern check here.

class HttpClientSingletonWrapper : HttpClient
{
    private static readonly Lazy<HttpClientSingletonWrapper> Lazy= new Lazy<HttpClientSingletonWrapper>(()=>new HttpClientSingletonWrapper()); 

    public static HttpClientSingletonWrapper Instance {get { return Lazy.Value; }}

    private HttpClientSingletonWrapper()
    {
    }
}

Use the code as below.

var client = HttpClientSingletonWrapper.Instance;

i've been researching for that too but unfortunately the facebook device auth is still on experimental and they didn't give new keys (partner) to use the device auth.

You can find the working example here: http://oauth-device-demo.appspot.com/ Just look at the website source and you can have the appID that works with it.

The other one is twitter PIN oauth it's working and publicly available (i'm using it) https://dev.twitter.com/docs/auth/pin-based-authorization

Instead of a List<UserRole>, you can let your Model contain a SelectList<UserRole>. Also add a property SelectedUserRoleId to store... well... the selected UserRole's Id value.

Fill up the SelectList, then in your View use:

@Html.DropDownListFor(x => x.SelectedUserRoleId, x.UserRole)

and you should be fine.

See also http://msdn.microsoft.com/en-us/library/system.web.mvc.selectlist(v=vs.108).aspx.

The logic will be:

SELECT * FROM objects WHERE Date LIKE '$_POST[period]-%';

In your case there are 3 extra y axis (4 in total) and the best code that could be used to achieve what you want and deal with other cases is illustrated above:

clear
clc

x = linspace(0,1,10);
N = numel(x);
y = rand(1,N);
y_extra_1 = 5.*rand(1,N)+5;
y_extra_2 = 50.*rand(1,N)+20;
Y = [y;y_extra_1;y_extra_2];

xLimit = [min(x) max(x)];
xWidth = xLimit(2)-xLimit(1);
numberOfExtraPlots = 2;
a = 0.05;
N_ = numberOfExtraPlots+1;

for i=1:N_
    L=1-(numberOfExtraPlots*a)-0.2;
    axesPosition = [(0.1+(numberOfExtraPlots*a)) 0.1 L 0.8];
    if(i==1)
        color = [rand(1),rand(1),rand(1)];
        figure('Units','pixels','Position',[200 200 1200 600])
        axes('Units','normalized','Position',axesPosition,...
            'Color','w','XColor','k','YColor',color,...
            'XLim',xLimit,'YLim',[min(Y(i,:)) max(Y(i,:))],...
            'NextPlot','add');
        plot(x,Y(i,:),'Color',color);
        xlabel('Time (s)');

        ylab = strcat('Values of dataset 0',num2str(i));
        ylabel(ylab)

        numberOfExtraPlots = numberOfExtraPlots - 1;
    else
        color = [rand(1),rand(1),rand(1)];
        axes('Units','normalized','Position',axesPosition,...
            'Color','none','XColor','k','YColor',color,...
            'XLim',xLimit,'YLim',[min(Y(i,:)) max(Y(i,:))],...
            'XTick',[],'XTickLabel',[],'NextPlot','add');
        V = (xWidth*a*(i-1))/L;
        b=xLimit+[V 0];
        x_=linspace(b(1),b(2),10);
        plot(x_,Y(i,:),'Color',color);
        ylab = strcat('Values of dataset 0',num2str(i));
        ylabel(ylab)

        numberOfExtraPlots = numberOfExtraPlots - 1;
    end
end

The code above will produce something like this:

Basically $(this).fadeOut().next().fadeIn(); is what you require

A cleaner way of iterating the lists is:

// initialise the collection
collection = new ArrayList<ArrayList<String>>();
// iterate
for (ArrayList<String> innerList : collection) {
    for (String string : innerList) {
        // do stuff with string
    }
}

While the above responses provide most of the answer it is useful--even this late to the question--to provide the full answer, to wit:

Array sub-expression (see about_arrays)

Forces the value to be an array, even if a singleton or a null, e.g. $a = @(ps | where name -like 'foo')

Hash initializer (see about_hash_tables)

Initializes a hash table with key-value pairs, e.g. $HashArguments = @{ Path = "test.txt"; Destination = "test2.txt"; WhatIf = $true }

Splatting (see about_splatting)

Let's you invoke a cmdlet with parameters from an array or a hash-table rather than the more customary individually enumerated parameters, e.g. using the hash table just above, Copy-Item @HashArguments

Here strings (see about_quoting_rules)

Let's you create strings with easily embedded quotes, typically used for multi-line strings, e.g.:

$data = @"
line one
line two
something "quoted" here
"@

Because this type of question (what does 'x' notation mean in PowerShell?) is so common here on StackOverflow as well as in many reader comments, I put together a lexicon of PowerShell punctuation, just published on Simple-Talk.com. Read all about @ as well as % and # and $_ and ? and more at The Complete Guide to PowerShell Punctuation. Attached to the article is this wallchart that gives you everything on a single sheet:

Your reference image looks like a button. Try (can also be done in Interface Builder):

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(50, 50, 100, 44)];
[button setImage:[UIImage imageNamed:@"img"] forState:UIControlStateNormal];
[button setImageEdgeInsets:UIEdgeInsetsMake(0, -30, 0, 0)];
[button setTitle:@"Abc" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor yellowColor]];
[view addSubview:button];

You can use this:

addedDate = datetime.now().replace(microsecond=0)

To round up an integer division you can use

import static java.lang.Math.abs;

public static long roundUp(long num, long divisor) {
    int sign = (num > 0 ? 1 : -1) * (divisor > 0 ? 1 : -1);
    return sign * (abs(num) + abs(divisor) - 1) / abs(divisor);
}

or if both numbers are positive

public static long roundUp(long num, long divisor) {
    return (num + divisor - 1) / divisor;
}

So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?

This is a good question or problem, but I suspect the answer is NO.

Also, a long int may not be a long long int.

# if __WORDSIZE == 64
typedef long int  int64_t;
# else
__extension__
typedef long long int  int64_t;
# endif

I believe this is libc. I suspect you want to go deeper.

In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:

int:           0
int64_t:       1
long int:      0
long long int: 1

32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long.

Microsoft documents the ranges at Data Type Ranges. The say the long long is equivalent to __int64.

However, the program resulting from a 64-bit GCC compile will output:

int:           0
int64_t:       1
long int:      1
long long int: 0

64-bit Linux uses the LP64 data model. Longs are 64-bit and long long are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64.

There's a ILP64 data model where everything is 64-bit. You have to do some extra work to get a definition for your word32 type. Also see papers like 64-Bit Programming Models: Why LP64?

But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...

Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive:

#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif

// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);

// Try it:
word64 val;
int res = rdrand64_step(&val);

It results in:

error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'

So, ignore LP64 and change it to:

typedef unsigned long long word64;

Then, wander over to a 64-bit ARM IoT gadget that defines LP64 and use NEON:

error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'

my_dict.update(key1='value1', key2='value2')

via dictionary unpacking

Since Python 3.5 you can also use dictionary unpacking for this:

my_dict = { **my_dict, 'key1': 'value1', 'key2': 'value2'}

Note: This creates a new dictionary.

via merge operator or update operator

Since Python 3.9 you can also use the merge operator on dictionaries:

my_dict = my_dict | {'key1': 'value1', 'key2': 'value2'}

Note: This creates a new dictionary.

Or you can use the update operator:

my_dict |= {'key1': 'value1', 'key2': 'value2'}

You could use the SQL%ROWCOUNT Oracle variable:

UPDATE table1
  SET field2 = value2, 
      field3 = value3 
WHERE field1 = value1; 

IF (SQL%ROWCOUNT = 0) THEN 

  INSERT INTO table (field1, field2, field3)
  VALUES (value1, value2, value3);

END IF; 

It would be easier just to determine if your primary key (i.e. field1) has a value and then perform an insert or update accordingly. That is, if you use said values as parameters for a stored procedure.

Correct attribute value for Asp.Net MVC Core to prevent browser caching (including Internet Explorer 11) is:

[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]

as described in Microsoft documentation:

If you want not to strip, but to actually convert latin accented to non-accented characters, take a look at this question: How do I translate 8bit characters into 7bit characters? (i.e. Ü to U)

Here are two extension methods you can use. They ensure any existing classes are preserved and do not duplicate classes being added.

public static void RemoveCssClass(this WebControl control, String css) {
  control.CssClass = String.Join(" ", control.CssClass.Split(' ').Where(x => x != css).ToArray());
}

public static void AddCssClass(this WebControl control, String css) {
  control.RemoveCssClass(css);
  css += " " + control.CssClass;
  control.CssClass = css;
}

Usage: hlCreateNew.AddCssClass("disabled");

Usage: hlCreateNew.RemoveCssClass("disabled");

Had this when I accidentally was calling

mapper.convertValue(...)

instead of

mapper.readValue(...)

So, just make sure you call correct method, since argument are same and IDE can find many things

You'll need to add a reference to System.Configuration in your project's references folder.

You should definitely be using the ConfigurationManager over the obsolete ConfigurationSettings.

If you want a comamnd that both accepts input from pipeline or as paramater, you should try this:

function which($name) {
    if ($name) { $input = $name }
    Get-Command $input | Select-Object -ExpandProperty Path
}

copy-paste the command to your profile (notepad $profile).

Examples:

? echo clang.exe | which
C:\Program Files\LLVM\bin\clang.exe

? which clang.exe
C:\Program Files\LLVM\bin\clang.exe

GO
CREATE TABLE t6(id int IDENTITY);
CREATE TABLE t7(id int IDENTITY(100,1));
GO
CREATE TRIGGER t6ins ON t6 FOR INSERT

BEGIN
   INSERT t7 DEFAULT VALUES
END;
GO
--End of trigger definition

SELECT id FROM t6;
--IDs empty.

SELECT id FROM t7;
--ID is empty.

--Do the following in Session 1
INSERT t6 DEFAULT VALUES;
SELECT @@IDENTITY;
/*Returns the value 100. This was inserted by the trigger.*/

SELECT SCOPE_IDENTITY();
/* Returns the value 1. This was inserted by the 
INSERT statement two statements before this query.*/

SELECT IDENT_CURRENT('t7');
/* Returns value inserted into t7, that is in the trigger.*/

SELECT IDENT_CURRENT('t6');
/* Returns value inserted into t6. This was the INSERT statement four statements before this query.*/

-- Do the following in Session 2.
SELECT @@IDENTITY;
/* Returns NULL because there has been no INSERT action 
up to this point in this session.*/

SELECT SCOPE_IDENTITY();
/* Returns NULL because there has been no INSERT action 
up to this point in this scope in this session.*/

SELECT IDENT_CURRENT('t7');
/* Returns the last value inserted into t7.*/

This could also be a simple syntax error. I had a syntax error which threw on FF but not Chrome as follows:

Never put ListView in ScrollView. ListView itself is scrollable.

if you use EclipseLink: You should be in a JPA transaction to access the Connection

entityManager.getTransaction().begin();
java.sql.Connection connection = entityManager.unwrap(java.sql.Connection.class);
...
entityManager.getTransaction().commit();

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

Since the web.config is XML, you need to escape the five special characters:

& -> & ampersand, U+0026
< -> < left angle bracket, less-than sign, U+003C
> -> > right angle bracket, greater-than sign, U+003E
" -> " quotation mark, U+0022
' -> ' apostrophe, U+0027

+ is not a problem, I suppose.

Duc Filan adds: You should also wrap your password with single quote ':

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

On window

import os
os.system("start \"\" https://example.com")

On macOS

import os
os.system("open \"\" https://example.com")

On Linux

import os
os.system("xdg-open \"\" https://example.com")

Cross-Platform

import webbrowser

webbrowser.open('https://example.com')

Sometimes when using open(filepath) in which filepath actually is not a file would get the same error, so firstly make sure the file you're trying to open exists:

import os
assert os.path.isfile(filepath)

**What's the best way to avoid a fixed size, i.e., to have the embedded website scale responsively to the browser's window size? I'd like to avoid scroll bars within my website. – CGFoX Feb 2 '19 at 15:52

**Is it possible to set width and height to percentages instead of absolute pixels? – CGFoX Mar 16 at 11:53

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

You can do quite a lot with plain css...the css property background-size can be set to a number of things as well as just cover as Ranjith pointed out.

The background-size: cover setting scales the image to cover the entire screen but may mean that some of the image is off screen if the aspect ratio of the screen and image are different.

A good alternative is background-size: contain which resizes the background image to fit the smaller of width and height, ensuring that the whole image is visible but may lead to letterboxing if the aspect ratios are different.

For example:

body {
      background: url(/images/bkgd.png) no-repeat rgb(30,30,30) fixed center center;
      background-size: contain;
     }

The other options that I find less useful are: background-size: length <widthpx> <heightpx> which sets the absolute size of the background image. background-size: percentage <width> <height> background image is a percentage of the window size. (see w3schools.com's page)

I am currently working on an open-source disassembler / decompiler called Assembly Analyzer. It generates source code for methods, displays assembly metadata and resources, and allows you to walk through dependencies.

The project is hosted on CodePlex => http://asmanalyzer.codeplex.com/

For what it's worth here are the step by step instructions for doing this in an Android device. Should be the same for iOS:

1. Open Charles
2. Go to Proxy > Proxy Settings > SSL
3. Check “Enable SSL Proxying”
4. Select “Add location” and enter the host name and port (if needed)
5. Click ok and make sure the option is checked
6. Download the Charles cert from here: Charles cert >
7. Send that file to yourself in an email.
8. Open the email on your device and select the cert
9. In “Name the certificate” enter whatever you want
10. Click OK and you should get a message that the certificate was installed

You should then be able to see the SSL files in Charles. If you want to intercept and change the values you can use the "Map Local" tool which is really awesome:

1. In Charles go to Tools > Map Local
2. Select "Add entry"
3. Enter the values for the file you want to replace
4. In “Local path” select the file you want the app to load instead
5. Click OK
6. Make sure the entry is selected and click OK
7. Run your app
8. You should see in “Notes” that your file loads instead of the live one

If @Maleki's answer isn't working for you, check and see if you have an .editorconfig file in your project folder.

For example the Angular CLI generates one with a new project that looks like this

# Editor configuration, see http://editorconfig.org
root = true

[*]
charset = utf-8
indent_style = space
indent_size = 2
insert_final_newline = true
trim_trailing_whitespace = true

[*.md]
max_line_length = off
trim_trailing_whitespace = false

Changing the indent_size here is required as it seems it will override anything in your .vscode workspace or user settings.

This is the job for style property:

ping -n 11 -w 1000 127.0.0.1 > nul

Update

Beginner's mistake. Ping doesn't wait 1000 ms before or after an request, but inbetween requests. So to wait 10 seconds, you'll have to do 11 pings to have 10 'gaps' of a second inbetween.

MySQL now has support for spatial data types since this question was asked. So the the current accepted answer is not wrong, but if you're looking for additional functionality like finding all points within a given polygon then use POINT data type.

I think the most robust solution that will insure that it is posted in uppercase is to use the oninput method inline like:

<input oninput="this.value = this.value.toUpperCase()" />

EDIT

Some people have been complaining that the cursor jumps to the end when editing the value, so this slightly expanded version should resolve that

<input oninput="let p=this.selectionStart;this.value=this.value.toUpperCase();this.setSelectionRange(p, p);" />

for OS's that support select:

import select

# your code

select.select([], [], [])

There are multiple ways to set profiles for your springboot application.

1. You can add this in your property file:

   spring.profiles.active=dev
   

2. Programmatic way:

   SpringApplication.setAdditionalProfiles("dev");
   

3. Tests make it very easy to specify what profiles are active

   @ActiveProfiles("dev")
   

4. In a Unix environment

   export spring_profiles_active=dev
   

5. JVM System Parameter

   -Dspring.profiles.active=dev
   

Example: Running a springboot jar file with profile.

java -jar -Dspring.profiles.active=dev application.jar

If you happen to be using Mono, then you might be interested to know that Mono 2.8 (to be released later this year) will have a performance counter which reports the physical memory size on all the platforms Mono runs on (including Windows). You would retrieve the value of the counter using this code snippet:

using System;
using System.Diagnostics;

class app
{
   static void Main ()
   {
       var pc = new PerformanceCounter ("Mono Memory", "Total Physical Memory");
       Console.WriteLine ("Physical RAM (bytes): {0}", pc.RawValue);
   }
}

If you are interested in C code which provides the performance counter, it can be found here.

Its mid 2019 and I faced this error after a few years of developing with Django. Baffled me for an entire night! It wasn't allowed host (which should throw a 400), everything else checked out, finally did some error logging only to discover that some missing / or messed up static files manifest (after collectstatic) were screwing with the setup. Long story short, for those who are stumped AND SO HAPPEN ARE USING WHITENOISE OR THE DJANGO STATICFILE BACKEND WITH CACHE (manifest static files) , maybe this is for you.

1. Make sure you setup everything (as I did for the whitenoise backend...django backends read on nonetheless) http://whitenoise.evans.io/en/stable/django.html

2. If error code 500 still shoots you down, take note on your settings.STATICFILES_STORAGE.

Set it to either (for whitenoise backend with compression)

STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'

or (leave as django default)

STATICFILES_STORAGE = django.contrib.staticfiles.storage.StaticFilesStorage

All in all, THE PROBLEM seemed to come from the fact that this whitenoise cache + compression backend -->

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

or the django's own caching backend -->

STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'

...didnt quite work well for me, since my css was referencing some other sources which may be mixed up during collectstatic / backend caching. This issue is also potentially highlighted in http://whitenoise.evans.io/en/stable/django.html#storage-troubleshoot

input width is 10 + 2 times 1 px for border

For a matrix you can use this:

[M,I] = max(A(:))

I is the index of A(:) containing the largest element.

Now, use the ind2sub function to extract the row and column indices of A corresponding to the largest element.

[I_row, I_col] = ind2sub(size(A),I)

source: https://www.mathworks.com/help/matlab/ref/max.html

One con I can think of is if you need really fast access to your data in your view (for example, game animation data like bone positions.) It is very inefficient to keep a layer of separation in this case.

Otherwise, for most other applications which are more data driven than graphics driven, it seems like a logical way to drive a UI.

import sys
userinput = sys.stdin.readline()
betAmount = int(userinput)

print betAmount

This works on my system. I checked int('23\n') would result in 23.

It should be enough to do:

$this->validate($request, [
    'password' => 'sometimes,min:6,confirmed,required_with:password_confirmed',
]);

Make password optional, but if present requires a password_confirmation that matches, also make password required only if password_confirmed is present

Given an array you can use the Array.ConvertAll method:

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below:

int[] myInts = Array.ConvertAll(arr, int.Parse);

A LINQ solution is similar, except you would need the extra ToArray call to get an array:

int[] myInts = arr.Select(int.Parse).ToArray();

What exactly do you mean by "starts my php script"? What kind of PHP script? One to generate an HTML response for an end-user, or one that simply performs some kind of data processing task? If you are familiar with using the tag and how it interacts with PHP, then you should only need to POST to your target PHP script using an button of type "submit". If you are not familiar with forms, take a look here.

Also you can use this

private static final String ALLOWED_URI_CHARS = "@#&=*+-_.,:!?()/~'%";
String urlEncoded = Uri.encode(path, ALLOWED_URI_CHARS);

it's the most simple method

In case your text is compressed inside the blob using DEFLATE algorithm and it's quite large, you can use this function to read it

CREATE OR REPLACE PACKAGE read_gzipped_entity_package AS

FUNCTION read_entity(entity_id IN VARCHAR2)
  RETURN VARCHAR2;

END read_gzipped_entity_package;
/

CREATE OR REPLACE PACKAGE BODY read_gzipped_entity_package IS

FUNCTION read_entity(entity_id IN VARCHAR2) RETURN VARCHAR2
IS
    l_blob              BLOB;
    l_blob_length       NUMBER;
    l_amount            BINARY_INTEGER := 10000; -- must be <= ~32765.
    l_offset            INTEGER := 1;
    l_buffer            RAW(20000);
    l_text_buffer       VARCHAR2(32767);
BEGIN
    -- Get uncompressed BLOB
    SELECT UTL_COMPRESS.LZ_UNCOMPRESS(COMPRESSED_BLOB_COLUMN_NAME)
    INTO   l_blob
    FROM   TABLE_NAME
    WHERE  ID = entity_id;

    -- Figure out how long the BLOB is.
    l_blob_length := DBMS_LOB.GETLENGTH(l_blob);

    -- We'll loop through the BLOB as many times as necessary to
    -- get all its data.
    FOR i IN 1..CEIL(l_blob_length/l_amount) LOOP

        -- Read in the given chunk of the BLOB.
        DBMS_LOB.READ(l_blob
        ,             l_amount
        ,             l_offset
        ,             l_buffer);

        -- The DBMS_LOB.READ procedure dictates that its output be RAW.
        -- This next procedure converts that RAW data to character data.
        l_text_buffer := UTL_RAW.CAST_TO_VARCHAR2(l_buffer);

        -- For the next iteration through the BLOB, bump up your offset
        -- location (i.e., where you start reading from).
        l_offset := l_offset + l_amount;
    END LOOP;
    RETURN l_text_buffer;
EXCEPTION
    WHEN OTHERS THEN
        DBMS_OUTPUT.PUT_LINE('!ERROR: ' || SUBSTR(SQLERRM,1,247));
END;

END read_gzipped_entity_package;
/

Then run select to get text

SELECT read_gzipped_entity_package.read_entity('entity_id') FROM DUAL;

Hope this will help someone.

When using the attribute to restrict the maximum input length for text from a form on a webpage, the StringLength seems to generate the maxlength html attribute (at least in my test with MVC 5). The one to choose then depnds on how you want to alert the user that this is the maximum text length. With the stringlength attribute, the user will simply not be able to type beyond the allowed length. The maxlength attribute doesn't add this html attribute, instead it generates data validation attributes, meaning the user can type beyond the indicated length and that preventing longer input depends on the validation in javascript when he moves to the next field or clicks submit (or if javascript is disabled, server side validation). In this case the user can be notified of the restriction by an error message.

No other "addClass" methods worked for me when adding a class to an 'a' element on menu except this one:

$(function () {
        var url = window.location.pathname,
    urlRegExp = new RegExp(url.replace(/\/$/, '') + "$");  
        $('a').each(function () {
                            if (urlRegExp.test(this.href.replace(/\/$/, ''))) {
                $(this).addClass('active');
            }
        });
    });

This took me four hours to find it.

Sounds like you want a view instead of altering actual table data.

Coalesce(NullIf(rtrim(Address.Country),''),'United States')

This will force your column to be null if it is actually an empty string (or blank string) and then the coalesce will have a null to work with.

There are many ways you can import Text file to the current sheet. Here are three (including the method that you are using above)

1. Using a QueryTable
2. Open the text file in memory and then write to the current sheet and finally applying Text To Columns if required.
3. If you want to use the method that you are currently using then after you open the text file in a new workbook, simply copy it over to the current sheet using Cells.Copy

Using a QueryTable

Here is a simple macro that I recorded. Please amend it to suit your needs.

Sub Sample()
    With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;C:\Sample.txt", Destination:=Range("$A$1") _
        )
        .Name = "Sample"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 437
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = True
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = True
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
End Sub

Open the text file in memory

Sub Sample()
    Dim MyData As String, strData() As String

    Open "C:\Sample.txt" For Binary As #1
    MyData = Space$(LOF(1))
    Get #1, , MyData
    Close #1
    strData() = Split(MyData, vbCrLf)
End Sub

Once you have the data in the array you can export it to the current sheet.

Using the method that you are already using

Sub Sample()
    Dim wbI As Workbook, wbO As Workbook
    Dim wsI As Worksheet

    Set wbI = ThisWorkbook
    Set wsI = wbI.Sheets("Sheet1") '<~~ Sheet where you want to import

    Set wbO = Workbooks.Open("C:\Sample.txt")

    wbO.Sheets(1).Cells.Copy wsI.Cells

    wbO.Close SaveChanges:=False
End Sub

FOLLOWUP

You can use the Application.GetOpenFilename to choose the relevant file. For example...

Sub Sample()
    Dim Ret

    Ret = Application.GetOpenFilename("Prn Files (*.prn), *.prn")

    If Ret <> False Then
        With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;" & Ret, Destination:=Range("$A$1"))

            '~~> Rest of the code

        End With
    End If
End Sub

Array values = Enum.GetValues(typeof(myEnum));

foreach( MyEnum val in values )
{
   Console.WriteLine (String.Format("{0}: {1}", Enum.GetName(typeof(MyEnum), val), val));
}

Or, you can cast the System.Array that is returned:

string[] names = Enum.GetNames(typeof(MyEnum));
MyEnum[] values = (MyEnum[])Enum.GetValues(typeof(MyEnum));

for( int i = 0; i < names.Length; i++ )
{
    print(names[i], values[i]);
}

But, can you be sure that GetValues returns the values in the same order as GetNames returns the names ?

The following worked for me:

Go to project properties. Web tab. Set to Local IIS and set specific page.

I have Windows 7 and Visual Studio 2013.

Just adding that you can pass the link_to method a block:

<%= link_to href: 'http://www.example.com/' do %>
    <%= image_tag 'happyface.png', width: 136, height: 67, alt: 'a face that is unnervingly happy'%>
<% end %>

results in:

<a href="/?href=http%3A%2F%2Fhttp://www.example.com/k%2F">
    <img alt="a face that is unnervingly happy" height="67" src="/assets/happyface.png" width="136">
</a>

This has been a life saver when the designer has given me complex links with fancy css3 roll-over effects.

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

Will make things like 12. accepted. This is not what is commonly accepted but if in case you need to be “flexible”, that is one way to go. And of course [0-9] can be replaced with \d, but I guess it’s more readable this way.

This deeply copies arrays, objects, null and other scalar values, and also deeply copies any properties on non-native functions (which is pretty uncommon but possible). (For efficiency, we do not attempt to copy non-numeric properties on arrays.)

function deepClone (item) {
  if (Array.isArray(item)) {
    var newArr = [];
    for (var i = item.length; i-- > 0;) {
      newArr[i] = deepClone(item[i]);
    }
    return newArr;
  }
  if (typeof item === 'function' && !(/\(\) \{ \[native/).test(item.toString())) {
    var obj;
    eval('obj = '+ item.toString());
    for (var k in item) {
      obj[k] = deepClone(item[k]);
    }
    return obj;
  }
  if (item && typeof item === 'object') {
    var obj = {};
    for (var k in item) {
      obj[k] = deepClone(item[k]);
    }
    return obj;
  }
  return item;
}

Simple solution which worked for me.

1. Install Vim editor for windows.
2. Open VS 2012 project solution using Vim editor and modify the version targetting Visual studio solution 10.
3. Open solution with Visual studio 2010.. and continue with your work ;)

If anyone has similar issue of having a phone with a cracked screen and has a need to access adb:

1. Root your phone (mine was already rooted, so I was blessed at least with that).

If you forgot to enable developers mode and your adb isn't running, then do the following:

1. Reboot your phone into recovery.
2. Connect the phone with a cable.
3. Open terminal.
4. If you type adb devices you should see the device in the list.

5. If so, type:

   adb shell mount /system
   abd shell
   
   echo "persist.service.adb.enable=1" >> default.prop 
   echo "persist.service.debuggable=1" >> default.prop
   echo "persist.sys.usb.config=mtp,adb" >> default.prop
   echo "persist.service.adb.enable=1" >> /system/build.prop 
   echo "persist.service.debuggable=1" >> /system/build.prop
   echo "persist.sys.usb.config=mtp,adb" >> /system/build.prop
   

Now if you are going to reboot into your phone android will tell you "oh your adb is working but please tap on this OK button, so we can trust your PC". And obviously if we can't tap on the phone stay in the recovery mode and do the following (assuming you are not in the adb shell mode, if so first type exit):

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

6. Hurray, it all should be hunky-dory now! Just reboot the phone and you should be able to access adb when the phone is running:

   adb shell reboot

P.S. Was using OS X and Moto X Style that's with the cracked screen.

It is not possible to limit the number of visible elements in the select dropdown (if you use it as dropdown box and not as list).

But you could use javascript/jQuery to replace this selectbox with something else, which just looks like a dropdown box. Then you can handle the height of dropdown as you want.

jNice would be a jQuery plugin which has such features. But there also exists many alternatives for that.

        int i=99;//is what row you want to select and focus
        listViewRamos.FocusedItem = listViewRamos.Items[0];
        listViewRamos.Items[i].Selected = true;
        listViewRamos.Select();
        listViewRamos.EnsureVisible(i);//This is the trick

since strings data types have variable length, it is by default stored as object dtype. If you want to store them as string type, you can do something like this.

df['column'] = df['column'].astype('|S80') #where the max length is set at 80 bytes,

or alternatively

df['column'] = df['column'].astype('|S') # which will by default set the length to the max len it encounters

Check for log4j configuration files in your output (i.e. bin or target/classes) directory or within generated project artifacts (.jar/.war/.ear). If this is on your classpath it gets picked up by log4j.

I assume that you want them sorted by something else also, to get a consistent ordering between all items where AVC is the same. For example by name:

var sortedList = list.OrderBy(x => c.AVC).ThenBy(x => x.Name).ToList();

If the other solutions aren't working, you may want to try importing Glyphicons from an external source, rather than relying on Bootstrap to do everything for you. To do this:

You can either do this in HTML:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">

Or CSS:

@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css")

A comprehensive list of browser versions supporting the async parameter is available here

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

See: Mozilla Developer Network - The X-Frame-Options response header

Here's the important part from the man page:

As the list of files/directories to transfer is built, rsync checks each name to be transferred against the list of include/exclude patterns in turn, and the first matching pattern is acted on: if it is an exclude pattern, then that file is skipped; if it is an include pattern then that filename is not skipped; if no matching pattern is found, then the filename is not skipped.

To summarize:

• Not matching any pattern means a file will be copied!
• The algorithm quits once any pattern matches

Also, something ending with a slash is matching directories (like find -type d would).

Let's pull apart this answer from above.

rsync -zarv  --prune-empty-dirs --include "*/"  --include="*.sh" --exclude="*" "$from" "$to"

1. Don't skip any directories
2. Don't skip any .sh files
3. Skip everything
4. (Implicitly, don't skip anything, but the rule above prevents the default rule from ever happening.)

Finally, the --prune-empty-directories keeps the first rule from making empty directories all over the place.

If you want to change query params without change the route. see below example might help you: current route is : /search & Target route is(without reload page) : /search?query=love

    submit(value: string) {
      this.router.navigate( ['.'],  { queryParams: { query: value } })
        .then(_ => this.search(q));
    }
    search(keyword:any) { 
    //do some activity using }

please note : you can use this.router.navigate( ['search'] instead of this.router.navigate( ['.']

Using a (very) commonly used package is prefered:

im = plt.imread('image.png')
