You can also check if a particular docker container is running or not using following command:

docker inspect postgres | grep "Running"

This command will check if for example my postgres container is running or not and will return output as "Running": true

Hope this helps.

1. clusterIP : IP accessible inside cluster (across nodes within d cluster).

nodeA : pod1 => clusterIP1, pod2 => clusterIP2
nodeB : pod3 => clusterIP3.

pod3 can talk to pod1 via their clusterIP network.

2. nodeport : to make pods accessible from outside the cluster via nodeIP:nodeport, it will create/keep clusterIP above as its clusterIP network.

nodeA => nodeIPA : nodeportX
nodeB => nodeIPB : nodeportX

you might access service on pod1 either via nodeIPA:nodeportX OR nodeIPB:nodeportX. Either way will work because kube-proxy (which is installed in each node) will receive your request and distribute it [redirect it(iptables term)] across nodes using clusterIP network.

3. Load balancer

basically just putting LB in front, so that inbound traffic is distributed to nodeIPA:nodeportX and nodeIPB:nodeportX then continue with the process flow number 2 above.

If you add double paranthesis to the ngModel reference you get a two-way binding to your model property. That property can then be read and used in the event handler. In my view that is the most clean approach.

<input type="checkbox" [(ngModel)]="myModel.property" (ngModelChange)="processChange()" />

something like this would probably work

class MyClass:
    def __init__(self,x,y,z):
       self.x = x
       self.y = y
       self.z = z
    def __iter__(self): #overridding this to return tuples of (key,value)
       return iter([('x',self.x),('y',self.y),('z',self.z)])

dict(MyClass(5,6,7)) # because dict knows how to deal with tuples of (key,value)

From your post, I understand that you cannot set the width to your li.

How about this?

ul {
  border:2px solid red;
  display:inline-block;
}

li {
  display:inline;
  padding:0 30%; /* try adjusting the side % to give a feel of center aligned.*/
}

<ul>
    <li>Hello</li>
    <li>Hezkdhkfskdhfkllo</li>
    <li>Hello</li>
</ul>

Here's a demo. http://codepen.io/anon/pen/HhBwx

You need to make sure the IIS Management Console is installed.

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

Use getApplicationContext() if you need something tied to a Context that itself will have global scope.

If you use Activity, then the new Activity instance will have a reference, which has an implicit reference to the old Activity, and the old Activity cannot be garbage collected.

SQLite doesn't support removing or modifying columns, apparently. But do remember that column data types aren't rigid in SQLite, either.

On some level Chris Pietschmann is correct. SQL isn't Turing complete (at least without stored procedures) yet people will list that as a language, TeX is Turing complete but most people regard it as a markup language.

Having said that: if you are just applying for jobs, not arguing formal logic, I would just list them all as technologies. Things like .NET aren't languages but would probably be listed as well.

Here's a reasonably sized bash script solution

#!/bin/bash
(
IFS=$'\n'
    for y in $(ls $1)
      do
         mv $1/`echo $y | sed 's/ /\\ /g'` $1/`echo "$y" | sed 's/ /_/g'`
      done
)

Your syntax is slightly wrong. Say:

*/15 * * * * command
  |
  |--> `*/15` would imply every 15 minutes.

* indicates that the cron expression matches for all values of the field.

/ describes increments of ranges.

Maybe not a direct answer to the question, but a recent addition to the official documentation describes how jQuery can be used to disable transitions entirely just by:

$.support.transition = false

Setting the .collapsing CSS transitions to none as mentioned in the accepted answer removed the animation. But this — in Firefox and Chromium for me — creates an unwanted visual issue on collapse of the navbar.

For instance, visit the Bootstrap navbar example and add the CSS from the accepted answer:

.collapsing {
     -webkit-transition: none;
     transition: none;
}

What I currently see is when the navbar collapses, the bottom border of the navbar momentarily becomes two pixels instead of one, then disconcertingly jumps back to one. Using jQuery, this artifact doesn't appear.

I get the same error in Chrome after pasting code copied from jsfiddle.

If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

If you are installing PHP 7.1.14 on windows server 2008 rc2 Enterprise, only thing worked for me is to install microsoft Visual C++ 2015 Redistributable Update 3 from https://www.microsoft.com/en-us/download/details.aspx?id=53587

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

This will give you the current fragment class name -->

String fr_name = getSupportFragmentManager().findFragmentById(R.id.fragment_container).getClass().getSimpleName();

Update to the latest release

Since this commit, this is is fixed in the development version of Tomcat. And now in released versions 9.0.13, 8.5.35, and 7.0.92.

From the 9.0.13 changelog:

Ignore an attribute named source on Context elements provided by StandardContext. This is to suppress warnings generated by the Eclipse / Tomcat integration provided by Eclipse. Based on a patch by mdfst13. (markt)

There are similar entries in the 7.0.92 and 8.5.35 changelogs.

The effect of this change is to suppress a warning when a source attribute is declared on a Context element in either server.xml or a context.xml. Since those are the two places that Eclipse puts such an attribute, that fixes this particular issue.

TL;DR: update to the latest Tomcat version in its branch, e.g. 9.0.13 or newer.

Just to point out that if you throw a checked exception in a code and the catch is few levels above, you need to declare the exception in the signature of each method between you and the catch. So, encapsulation is broken because all functions in the path of throw must know about details of that exception.

The conventional way of handling this doesn't play well with ES6. You can do this instead:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);

  this.delete(clickedElement.data('id'));
});

Note that the event target will be the clicked element, which may not be the element you want (it could be a child that received the event). To get the actual element:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);
  const targetElement = clickedElement.closest('.delete');

  this.delete(targetElement.data('id'));
});

Before actually using GUI dialogues, consider using console prompts. Quite often you can get away with simple "y/n?" prompts, which in bash you achieve via the read command..

read -p "Do something? ";
if [ $REPLY == "y" ]; then
    echo yay;
fi

If console prompt's just won't cut it, Zenity is really easy to use, for example:

      zenity --error --text="Testing..."
      zenity --question --text="Continue?"

This only works on Linux/Gnome (or rather, it'll only be installed by default on such systems). The read method will work on pretty much any platform (including headless machines, or via SSH)

If you need anything more complex than what read or Zenity provides, "change to C++" is really the best method (although I'd recommend Python/Ruby over C++ for such shell-script-replacement tasks)

I want to do simple interface for some strange game, the progress bar for health or something is the example for what I want. Variable "HEALTH" is 34, so make progress bar filled in 34/100

As a command-line script, it'd use Python:

$ export HEALTH=34
$ python -c "import os; print '*' * int(os.environ.get('HEALTH', 0))"
**********************************

Or to normalise the values between 1 and 78 (so you don't get line-wrapping on a standard terminal size):

$ python -c "import os; print '*' * int((int(os.environ.get('HEALTH', 0)) / 100.0) * 78)"

Zenity also has a Progress Dialog,

#!/bin/sh
(
echo "10" ; sleep 1
echo "# Updating mail logs" ; sleep 1
echo "20" ; sleep 1
echo "# Resetting cron jobs" ; sleep 1
echo "50" ; sleep 1
echo "This line will just be ignored" ; sleep 1
echo "75" ; sleep 1
echo "# Rebooting system" ; sleep 1
echo "100" ; sleep 1
) |
zenity --progress \
  --title="Update System Logs" \
  --text="Scanning mail logs..." \
  --percentage=0

if [ "$?" = -1 ] ; then
        zenity --error \
          --text="Update canceled."
fi

As I said before, if Zenity cannot do what you need, look into writing your game-thing as a "proper" script in Python/Ruby/Perl/C++/etc as it sounds like you're pushing the bounds of what a shell-script can do..

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

In 4.0 version of the .Net framework the ServicePointManager.SecurityProtocol only offered two options to set:

• Ssl3: Secure Socket Layer (SSL) 3.0 security protocol.
• Tls: Transport Layer Security (TLS) 1.0 security protocol

In the next release of the framework the SecurityProtocolType enumerator got extended with the newer Tls protocols, so if your application can use th 4.5 version you can also use:

• Tls11: Specifies the Transport Layer Security (TLS) 1.1 security protocol
• Tls12: Specifies the Transport Layer Security (TLS) 1.2 security protocol.

So if you are on .Net 4.5 change your line

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

to

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

so that the ServicePointManager will create streams that support Tls12 connections.

Do notice that the enumeration values can be used as flags so you can combine multiple protocols with a logical OR

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | 
                                       SecurityProtocolType.Tls11 |
                                       SecurityProtocolType.Tls12;

Note
Try to keep the number of protocols you support as low as possible and up-to-date with today security standards. Ssll3 is no longer deemed secure and the usage of Tls1.0 SecurityProtocolType.Tls is in decline.

What finally cleared this up for me was a comment showing that:

git checkout main
git merge --squash feature

is the equivalent of doing:

git checkout feature
git diff main > feature.patch
git checkout main
patch -p1 < feature.patch
git add .

When I want to merge a feature branch with 105(!!) commits and have them all squashed into one, I don't want to git rebase -i origin/master because I need to separately resolve merge conflicts for each of the intermediate commits (or at least the ones which git can't figure out itself). Using git merge --squash gets me the result I want, of a single commit for merging an entire feature branch. And, I only need to do at most one manual conflict resolution.

Firstly add a div with id.

<div id="my_map_add" style="width:100%;height:300px;"></div>

<script type="text/javascript">
function my_map_add() {
var myMapCenter = new google.maps.LatLng(28.5383866, 77.34916609);
var myMapProp = {center:myMapCenter, zoom:12, scrollwheel:false, draggable:false, mapTypeId:google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("my_map_add"),myMapProp);
var marker = new google.maps.Marker({position:myMapCenter});
marker.setMap(map);
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=your_key&callback=my_map_add"></script>

Event.preventDefault- stops browser default behaviour. Now comes what is browser default behaviour. Assume you have a anchor tag and it has got a href attribute and this anchor tag is nested inside a div tag which has got a click event. Default behaviour of anchor tag is when clicked on the anchor tag it should navigate, but what event.preventDefault does is it stops the navigation in this case. But it never stops the bubbling of event or escalation of event i.e

<div class="container">
 <a href="#" class="element">Click Me!</a>
</div>

$('.container').on('click', function(e) {
 console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  console.log('element was clicked');
});

The result will be

"element was clicked"

"container was clicked"

Now event.StopPropation it stops bubbling of event or escalation of event. Now with above example

$('.container').on('click', function(e) {
  console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  e.stopPropagation(); // Now the event won't bubble up
 console.log('element was clicked');
});

Result will be

"element was clicked"

Baron Schwartz blogs that due to race conditions, this 'check before write' is a bad practice. He advocates a try/catch pattern with a reconnect in the catch. Here is the pseudo code he recommends:

function query_database(connection, sql, retries=1)
   while true
      try
         result=connection.execute(sql)
         return result
      catch InactiveConnectionException e
         if retries > 0 then
            retries = retries - 1
            connection.reconnect()
         else
            throw e
         end
      end
   end
end

Since I am new to stackoverflow and have lesser reputation to comment on others' answers, I am putting the solution suggested by Chris Salij with some modification which worked for me.

            SSLContext ctx = null;
            TrustManager[] trustAllCerts = new X509TrustManager[]{new X509TrustManager(){
                public X509Certificate[] getAcceptedIssuers(){return null;}
                public void checkClientTrusted(X509Certificate[] certs, String authType){}
                public void checkServerTrusted(X509Certificate[] certs, String authType){}
            }};
            try {
                ctx = SSLContext.getInstance("SSL");
                ctx.init(null, trustAllCerts, null);
            } catch (NoSuchAlgorithmException | KeyManagementException e) {
                LOGGER.info("Error loading ssl context {}", e.getMessage());
            }

            SSLContext.setDefault(ctx);

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

Also something important to add here, in order to set default values for arrays and objects we must use the default function for props:

propE: {
      type: Object,
      // Object or array defaults must be returned from
      // a factory function
      default: function () {
        return { message: 'hello' }
      }
    },

You can also use try...except:

try:
    int(string[0])
    # do your stuff
except:
    pass # or do your stuff

You are missing the ? in the second URL (Also, it should be URL-encoded to be %3F).

Also, I believe that the remaining & need to be URL, not HTML-encoded. Change &second=12&third=5 to %26second=12%26third=5 and everything should just work.

This:

&u=http://www.foobar.com/first=12&sec=25&position=2

should be:

&u=http://www.foobar.com/%3Ffirst=12%26sec=25%26position=2

No, you can not import a class with the use keyword. You have to use include/require statement. Even if you use a PHP auto loader, still autoloader will have to use either include or require internally.

The Purpose of use keyword:

Consider a case where you have two classes with the same name; you'll find it strange, but when you are working with a big MVC structure, it happens. So if you have two classes with the same name, put them in different namespaces. Now consider when your auto loader is loading both classes (does by require), and you are about to use object of class. In this case, the compiler will get confused which class object to load among two. To help the compiler make a decision, you can use the use statement so that it can make a decision which one is going to be used on.

Nowadays major frameworks do use include or require via composer and psr

1) composer

2) PSR-4 autoloader

Going through them may help you further. You can also use an alias to address an exact class. Suppose you've got two classes with the same name, say Mailer with two different namespaces:

namespace SMTP;
class Mailer{}

and

namespace Mailgun;
class Mailer{}

And if you want to use both Mailer classes at the same time then you can use an alias.

use SMTP\Mailer as SMTPMailer;
use Mailgun\Mailer as MailgunMailer;

Later in your code if you want to access those class objects then you can do the following:

$smtp_mailer = new SMTPMailer;
$mailgun_mailer = new MailgunMailer;

It will reference the original class.

Some may get confused that then of there are not Similar class names then there is no use of use keyword. Well, you can use __autoload($class) function which will be called automatically when use statement gets executed with the class to be used as an argument and this can help you to load the class at run-time on the fly as and when needed.

Refer this answer to know more about class autoloader.

Quite late indeed but here it is

sed 's/.//3g'

Or

awk NF=1 FPAT=..

Or

perl -pe '$_=unpack a2'

Nope, no difference. It's just syntactic sugar. Arrays.asList(..) creates an additional list.

This works just fine for me:

INSERT INTO table VALUES ('', NULLIF('$date',''))

(first '' increments id field)

$(element).on("click mousedown mouseup focus blur keydown change",function(e){
     console.log(e);
});

That will get you a lot (but not all) of the information on if an event is fired... other than manually coding it like this, I can't think of any other way to do that.

Your variable size is declared as: float size;

You can't use a floating point variable as the size of an array - it needs to be an integer value.

You could cast it to convert to an integer:

float *temp = new float[(int)size];

Your other problem is likely because you're writing outside of the bounds of the array:

   float *temp = new float[size];

    //Getting input from the user
    for (int x = 1; x <= size; x++){
        cout << "Enter temperature " << x << ": ";

        // cin >> temp[x];
        // This should be:
        cin >> temp[x - 1];
    }

Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

a csv-file is just like any other file a stream of characters. the getline reads from the file up to a delimiter however in your case the delimiter for the last item is not ' ' as you assume

getline(file, genero, ' ') ; 

it is newline \n

so change that line to

getline(file, genero); // \n is default delimiter

Based on Compiling Sources Using A Different JDK, you will have to set the fork to true in your pom.xml file.

If you are storing keys/values as strings, then this will work:

HashMap<String, String> newMap = new HashMap<String, String>();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");

The question is what gets populated in the HashMap (key & value)

For a combobox (http://en.wikipedia.org/wiki/Combo_box) which allows free text input and has a dropdown listbox I used a AutoCompleteTextView as suggested by vbence.

I used the onClickListener to display the dropdown list box when the user selects the control.

I believe this resembles this kind of a combobox best.

private static final String[] STUFF = new String[] { "Thing 1", "Thing 2" };

public void onCreate(Bundle b) {
    final AutoCompleteTextView view = 
        (AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView);

    view.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
                view.showDropDown();
        }
    });

    final ArrayAdapter<String> adapter = new ArrayAdapter<String>(
        this, 
        android.R.layout.simple_dropdown_item_1line,
        STUFF
    );
    view.setAdapter(adapter);
}

I was able to fix this by toggling on/off "Game Center" entitlement in Xcode 5 :-)

You can use the JAVA 7 Files api

Path myDirectoryPath = Paths.get("path to my directory");
List<Path> subDirectories = Files.find(
                    myDirectoryPath ,
                    Integer.MAX_VALUE,
                    (filePath, fileAttr) -> fileAttr.isDirectory() && !filePath.equals(myDirectoryPath )
            ).collect(Collectors.toList());

If you want a specific value you can call map with the value you want before collecting the data.

In addition to the other answers on this question and its duplicates, here's a good way to get source code for a package function without needing to know which package it's in. e.g. say if we want the source for randomForest::rfcv():

To view/edit it in a pop-up window:

edit(getAnywhere('rfcv'), file='source_rfcv.r')

View(getAnywhere('rfcv'), file='source_rfcv.r')

Note that edit() opens a text editor (of user's choice), whereas View() invokes a spreadsheet-style data viewer.

• View() is great for browsing (multi-columnar) data, but usually terrible for code of anything other than toy length.
• so when only want to view code, edit() is IMO actually far better than View(), since with edit() you can collapse/hide/dummy out all the arg-parsing/checking/default/error-message logic which can take up to 70% of an R function, and just get to the part where the function actually operationally does something(!), what type(s) of objects its return type is, whether and how it recurses, etc.

To redirect to a separate file (so you can bring up the code in your favorite IDE/editor/process it with grep/etc.):

capture.output(getAnywhere('rfcv'), file='source_rfcv.r')

No formulas required. This works on as many columns as you need, but will only compare columns in the same worksheet:

NOTE: remove any duplicates from the individual columns first!

1. Select the columns to compare
2. click Conditional Formatting
3. click Highlight Cells Rules
4. click Duplicate Values (the defaults should be OK)

5. Duplicates are now highlighted in red

   • Bonus tip, you can filter each row by colour to either leave the unique values in the column, or leave just the duplicates.

You can find some demos and plugins here.

Here is how to get the Guid's programmatically! You can then use these guids/filepaths with an above answer to add the reference!

Reference: http://www.vbaexpress.com/kb/getarticle.php?kb_id=278

Sub ListReferencePaths()
'Lists path and GUID (Globally Unique Identifier) for each referenced library.
'Select a reference in Tools > References, then run this code to get GUID etc.
    Dim rw As Long, ref
    With ThisWorkbook.Sheets(1)
        .Cells.Clear
        rw = 1
        .Range("A" & rw & ":D" & rw) = Array("Reference","Version","GUID","Path")
        For Each ref In ThisWorkbook.VBProject.References
            rw = rw + 1
            .Range("A" & rw & ":D" & rw) = Array(ref.Description, _
                   "v." & ref.Major & "." & ref.Minor, ref.GUID, ref.FullPath)
        Next ref
        .Range("A:D").Columns.AutoFit
    End With
End Sub

Here is the same code but printing to the terminal if you don't want to dedicate a worksheet to the output.

Sub ListReferencePaths() 
 'Macro purpose:  To determine full path and Globally Unique Identifier (GUID)
 'to each referenced library.  Select the reference in the Tools\References

One option is using Object.keys():

Object.keys(driversCounter)

It works fine for modern browsers (however, Internet Explorer supports it starting from version 9 only).

To add compatible support you can copy the code snippet provided in MDN.

use <textarea></textarea> instead of leaving a space between the opening and closing tags as <textarea> </textarea>

In case you are uploading an sql file on cpanel, then try and replace root with your cpanel username in your sql file.

in the case above you could write

CREATE DEFINER = control_panel_username@localhost FUNCTION fnc_calcWalkedDistance

then upload the file. Hope it helps

The NoReverseMatch error is saying that Django cannot find a matching url pattern for the url you've provided in any of your installed app's urls.

The NoReverseMatch exception is raised by django.core.urlresolvers when a matching URL in your URLconf cannot be identified based on the parameters supplied.

To start debugging it, you need to start by disecting the error message given to you.

• NoReverseMatch at /my_url/

  This is the url that is currently being rendered, it is this url that your application is currently trying to access but it contains a url that cannot be matched

• Reverse for 'my_url_name'

  This is the name of the url that it cannot find

• with arguments '()' and

  These are the non-keyword arguments its providing to the url

• keyword arguments '{}' not found.

  These are the keyword arguments its providing to the url

• n pattern(s) tried: []

  These are the patterns that it was able to find in your urls.py files that it tried to match against

Start by locating the code in your source relevant to the url that is currently being rendered - the url, the view, and any templates involved. In most cases, this will be the part of the code you're currently developing.

Once you've done this, read through the code in the order that django would be following until you reach the line of code that is trying to construct a url for your my_url_name. Again, this is probably in a place you've recently changed.

Now that you've discovered where the error is occuring, use the other parts of the error message to work out the issue.

The url name

• Are there any typos?
• Have you provided the url you're trying to access the given name?
• If you have set app_name in the app's urls.py (e.g. app_name = 'my_app') or if you included the app with a namespace (e.g. include('myapp.urls', namespace='myapp'), then you need to include the namespace when reversing, e.g. {% url 'myapp:my_url_name' %} or reverse('myapp:my_url_name').

Arguments and Keyword Arguments

The arguments and keyword arguments are used to match against any capture groups that are present within the given url which can be identified by the surrounding () brackets in the url pattern.

Assuming the url you're matching requires additional arguments, take a look in the error message and first take a look if the value for the given arguments look to be correct.

If they aren't correct:

• The value is missing or an empty string

  This generally means that the value you're passing in doesn't contain the value you expect it to be. Take a look where you assign the value for it, set breakpoints, and you'll need to figure out why this value doesn't get passed through correctly.

• The keyword argument has a typo

  Correct this either in the url pattern, or in the url you're constructing.

If they are correct:

• Debug the regex

  You can use a website such as regexr to quickly test whether your pattern matches the url you think you're creating, Copy the url pattern into the regex field at the top, and then use the text area to include any urls that you think it should match against.

  Common Mistakes:

  • Matching against the . wild card character or any other regex characters

    Remember to escape the specific characters with a \ prefix

  • Only matching against lower/upper case characters

    Try using either a-Z or \w instead of a-z or A-Z

• Check that pattern you're matching is included within the patterns tried

  If it isn't here then its possible that you have forgotten to include your app within the INSTALLED_APPS setting (or the ordering of the apps within INSTALLED_APPS may need looking at)

Django Version

In Django 1.10, the ability to reverse a url by its python path was removed. The named path should be used instead.

If you're still unable to track down the problem, then feel free to ask a new question that includes what you've tried, what you've researched (You can link to this question), and then include the relevant code to the issue - the url that you're matching, any relevant url patterns, the part of the error message that shows what django tried to match, and possibly the INSTALLED_APPS setting if applicable.

Or you can simply do

ant jar

in your cloned volley git project. You should now see volley.jar in the volley projects bin folder. Copy this to you Android Studio's app\libs folder. Then add following under dependencies section of Module level build.gradle file -

compile files('libs/volley.jar')

And you should be good import and use the library classes in your project,

This gives you the root folder:

System.AppDomain.CurrentDomain.BaseDirectory

You can navigate from here using .. or ./ etc.. , Appending .. takes you to folder where .sln file can be found

For .NET framework (thanks to Adiono comment)

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"..\\..\\"))

For .NET core here is a way to do it (thanks to nopara73 comment)

Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, "..\\..\\..\\")) ;

The following simple code worked for me.

[imageView setContentMode:UIViewContentModeScaleAspectFill];
[imageView setClipsToBounds:YES];

Since PostgreSQL 9.1, installation of additional modules is simple. Registered extensions like dblink can be installed with CREATE EXTENSION:

CREATE EXTENSION dblink;

Installs into your default schema, which is public by default. Make sure your search_path is set properly before you run the command. The schema must be visible to all roles who have to work with it. See:

• How does the search_path influence identifier resolution and the "current schema"

Alternatively, you can install to any schema of your choice with:

CREATE EXTENSION dblink SCHEMA extensions;

See:

• Best way to install hstore on multiple schemas in a Postgres database?

Run once per database. Or run it in the standard system database template1 to add it to every newly created DB automatically. Details in the manual.

You need to have the files providing the module installed on the server first. For Debian and derivatives this would be the package postgresql-contrib-9.1 - for PostgreSQL 9.1, obviously. Since Postgres 10, there is just a postgresql-contrib metapackage.

Forget it, this is not doable.

No matter what you try it will not work. All a user needs to do to discover your code and it's location is to look in the net tab in firebug or use fiddler to see what requests are being made.

Disabling and Enabling the Developer options and debug mode on the Android phone settings fixed the issue.

$d="05/Feb/2010:14:00:01";
$dr= date_create_from_format('d/M/Y:H:i:s', $d);
echo $dr->format('Y-m-d H:i:s');

here you get date string, give format specifier in ->format() according to format needed

An easy and usable way to solve this problem

getGetSuppor(filter): Observale<any[]> {
   return this.https.get<any[]>('/api/callCenter/getSupport' + '?' + this.toQueryString(filter));
}

private toQueryString(query): string {
   var parts = [];
   for (var property in query) {
     var value = query[propery];
     if (value != null && value != undefined)
        parts.push(encodeURIComponent(propery) + '=' + encodeURIComponent(value))
   }
   
   return parts.join('&');
}

For Python 3:

import urllib.request, urllib.error

url = 'http://www.google.com/asdfsf'
try:
    conn = urllib.request.urlopen(url)
except urllib.error.HTTPError as e:
    # Return code error (e.g. 404, 501, ...)
    # ...
    print('HTTPError: {}'.format(e.code))
except urllib.error.URLError as e:
    # Not an HTTP-specific error (e.g. connection refused)
    # ...
    print('URLError: {}'.format(e.reason))
else:
    # 200
    # ...
    print('good')

String temp = passwordSalt;
byte[] byteSalt = temp.getBytes();
int start = 32;
for (int i = 0; i < byteData.length; i ++)
{
    byteData[start + i] = byteSalt[i];
}

The problem with your code here is that the variable i that is being used to index the arrays is going past both the byteSalt array and the byteData array. So, Make sure that byteData is dimensioned to be at least the maximum length of the passwordSalt string plus 32. What will correct it is replacing the following line:

for (int i = 0; i < byteData.length; i ++)

with:

for (int i = 0; i < byteSalt.length; i ++)

I found this one more helpful and simple

DECLARE @StartTime datetime,@EndTime datetime   
SELECT @StartTime=GETDATE() 
--Your Query to be run goes here--  
SELECT @EndTime=GETDATE()   
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in milliseconds]   

For those looking for a quick, easy solution - if you have a relatively consistent set of block content setting a min-height on the div that is a bit bigger than the largest block can be easier to implement.

.align-box {
    min-height: 400px;
}

Personally I used this in my HTML head tag:

<link rel="shortcut icon" href="#" />

There's no error here. You're printing a function, and that's what functions look like.

To actually call the function, you have to put parens after that. You're already doing that above. If you want to print the result of calling the function, just have the function return the value, and put the print there. For example:

print test.sort_word_list()

On the other hand, if you want the function to mutate the object's state, and then print the state some other way, that's fine too.

Now, your code seems to work in some places, but not others; let's look at why:

• parser sets a variable called word_list, and you later print test.word_list, so that works.
• sort_word_list sets a variable called sorted_word_list, and you later print test.sort_word_list—that is, the function, not the variable. So, you see the bound method. (Also, as Jon Clements points out, even if you fix this, you're going to print None, because that's what sort returns.)
• num_words sets a variable called num_words, and you again print the function—but in this case, the variable has the same name as the function, meaning that you're actually replacing the function with its output, so it works. This is probably not what you want to do, however.

(There are cases where, at first glance, that seems like it might be a good idea—you only want to compute something once, and then access it over and over again without constantly recomputing that. But this isn't the way to do it. Either use a @property, or use a memoization decorator.)

To get the smallest or largest item in a list, use the built-in min and max functions:

 lo = min(L)
 hi = max(L)  

As with sort, you can pass in a "key" argument that is used to map the list items before they are compared:

 lo = min(L, key=int)
 hi = max(L, key=int)

http://effbot.org/zone/python-list.htm

Looks like you could use the max function if you map it correctly for strings and use that as the comparison. I would recommend just finding the max once though of course, not for each element in the list.

Using CentOS7, logs are available using the command journalctl -u docker. Answering distinctly, because @sabin's answer might be accurate for older versions of CentOS but was not true for me.

systemd has its own logging system called the journal. The logs for the docker daemon can be viewed using journalctl -u docker

Assuming those methods are in one of the libs it looks like an ordering problem.

When linking libraries into an executable they are done in the order they are declared.
Also the linker will only take the methods/functions required to resolve currently outstanding dependencies. If a subsequent library then uses methods/functions that were not originally required by the objects you will have missing dependencies.

How it works:

• Take all the object files and combine them into an executable
• Resolve any dependencies among object files.
• For-each library in order:
  • Check unresolved dependencies and see if the lib resolves them.
  • If so load required part into the executable.

Example:

Objects requires:

• Open
• Close
• BatchRead
• BatchWrite

Lib 1 provides:

• Open
• Close
• read
• write

Lib 2 provides

• BatchRead (but uses lib1:read)
• BatchWrite (but uses lib1:write)

If linked like this:

gcc -o plop plop.o -l1 -l2

Then the linker will fail to resolve the read and write symbols.

But if I link the application like this:

gcc -o plop plop.o -l2 -l1

Then it will link correctly. As l2 resolves the BatchRead and BatchWrite dependencies but also adds two new ones (read and write). When we link with l1 next all four dependencies are resolved.

Your question is not particularly clear, but in case you want to send POST data to a url without using a form, you can use either fsockopen or curl.

Here's a pretty good walkthrough of both

From here.

the SQL standard requires that HAVING must reference only columns in the GROUP BY clause or columns used in aggregate functions

as opposed to the WHERE clause which is applied to database rows

I know that this has already been answered, but I wanted to share an answer that I gave to someone who asked a very similar question on a C/C++ Facebook group.

Arrays don't have assignment operator functions*. This means that you cannot simply assign a char array to a string literal. Why? Because the array itself doesn't have any assignment operator. (*It's a const pointer which can't be changed.)

arrays are simply an area of contiguous allocated memory and the name of the array is actually a pointer to the first element of the array. (Quote from https://www.quora.com/Can-we-copy-an-array-using-an-assignment-operator)

To copy a string literal (such as "Hello world" or "abcd") to your char array, you must manually copy all char elements of the string literal onto the array.

char s[100]; This will initialize an empty array of length 100.

Now to copy your string literal onto this array, use strcpy

strcpy(s, "abcd"); This will copy the contents from the string literal "abcd" and copy it to the s[100] array.

Here's a great example of what it's doing:

int i = 0; //start at 0
do {
    s[i] = ("Hello World")[i]; //assign s[i] to the string literal index i
} while(s[i++]); //continue the loop until the last char is null

You should obviously use strcpy instead of this custom string literal copier, but it's a good example that explains how strcpy fundamentally works.

Hope this helps!

2017 I know... but someone is facing this problem during their code maintenance.

This error happened when I tried:

maskedbox.Mask = "#.###"
maskedbox.Text = "12345678"

To fix that, just set PromptInclude property to "false".

If your file is strictly text, I prefer to use the java.util.Scanner class.

You can create a Scanner out of a file by:

Scanner fileIn = new Scanner(new File(thePathToYourFile));

Then, you can read text from the file using the methods:

fileIn.nextLine(); // Reads one line from the file
fileIn.next(); // Reads one word from the file

And, you can check if there is any more text left with:

fileIn.hasNext(); // Returns true if there is another word in the file
fileIn.hasNextLine(); // Returns true if there is another line to read from the file

Once you have read the text, and saved it into a String, you can print the string to the command line with:

System.out.print(aString);
System.out.println(aString);

The posted link contains the full specification for the Scanner class. It will be helpful to assist you with what ever else you may want to do.

After creating a second project in the workspace in eclipse, I had this problem. I believe it is because I created it with a different SDK version and this ovewrote the android-support-v7-appcompat library.

I tried to clean everything up but to no avail. Ultimately, the suggestion above to edit project.properties and change target=android-21 and set my project to Android 5.0, fixed it.

Using Swift 3 (Xcode 8.3)

 func deviceName() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let str = withUnsafePointer(to: &systemInfo.machine.0) { ptr in

Note: According to official dev forum answer, it is safe to use tuples in this way. Memory alignment for the big Int8 tuple will be the same as if it were a big Int8 array. ie: contiguous and not-padded.

New .NET 5 Solution:

In .NET 5, a new class has been introduced called JsonContent, which derives from HttpContent. See in Microsoft docs

This class has a static method called Create(), which takes an object as a parameter.

Usage:

var myObject = new
{
    foo = "Hello",
    bar = "World",
};

JsonContent content = JsonContent.Create(myObject);

HttpResponseMessage response = await _httpClient.PostAsync("https://...", content);

The first code line, Option Explicit means (in simple terms) that all of your variables have to be explicitly declared by Dim statements. They can be any type, including object, integer, string, or even a variant.

This line: Dim envFrmwrkPath As Range is declaring the variable envFrmwrkPath of type Range. This means that you can only set it to a range.

This line: Set envFrmwrkPath = ActiveSheet.Range("D6").Value is attempting to set the Range type variable to a specific Value that is in cell D6. This could be a integer or a string for example (depends on what you have in that cell) but it's not a range.

I'm assuming you want the value stored in a variable. Try something like this:

Dim MyVariableName As Integer
MyVariableName = ActiveSheet.Range("D6").Value

This assumes you have a number (like 5) in cell D6. Now your variable will have the value.

For simplicity sake of learning, you can remove or comment out the Option Explicit line and VBA will try to determine the type of variables at run time.

Try this to get through this part of your code

Dim envFrmwrkPath As String
Dim ApplicationName As String
Dim TestIterationName As String

In a Spring project you can use

UriComponentsBuilder.fromHttpRequest(new ServletServerHttpRequest(request)).build().toUriString()

You can use it to avoid defining global variables. This gives you an alternative for other designs. 3 designs presenting a solution to a problem.

A) Using functions without globals

def calculate_salary(employee, list_with_all_employees):
    x = _calculate_tax(list_with_all_employees)

    # some other calculations done to x
    pass

    y = # something 

    return y

def _calculate_tax(list_with_all_employees):
    return 1.23456 # return something

B) Using functions with globals

_list_with_all_employees = None

def calculate_salary(employee, list_with_all_employees):

    global _list_with_all_employees
    _list_with_all_employees = list_with_all_employees

    x = _calculate_tax()

    # some other calculations done to x
    pass

    y = # something

    return y

def _calculate_tax():
    return 1.23456 # return something based on the _list_with_all_employees var

C) Using functions inside another function

def calculate_salary(employee, list_with_all_employees):

    def _calculate_tax():
        return 1.23456 # return something based on the list_with_a--Lemployees var

    x = _calculate_tax()

    # some other calculations done to x
    pass
    y = # something 

    return y

Solution C) allows to use variables in the scope of the outer function without having the need to declare them in the inner function. Might be useful in some situations.

Extension of @Vincent 's answer:

For lm() generated models:

summary(fit)$coefficients[,4]   ##P-values 
summary(fit)$r.squared          ##R squared values

For gls() generated models:

summary(fit)$tTable[,4]         ##P-values
##R-squared values are not generated b/c gls uses max-likelihood not Sums of Squares

To isolate an individual p-value itself, you'd add a row number to the code:

For example to access the p-value of the intercept in both model summaries:

summary(fit)$coefficients[1,4]
summary(fit)$tTable[1,4]  

• Note, you can replace the column number with the column name in each of the above instances:

  summary(fit)$coefficients[1,"Pr(>|t|)"]  ##lm 
  summary(fit)$tTable[1,"p-value"]         ##gls 
  

If you're still unsure of how to access a value form the summary table use str() to figure out the structure of the summary table:

str(summary(fit))

If you want to use the upstream version:

rm -rf <submodule dir>
git submodule init
git submodule update

Here is my variant to have 'one statement to truncate 'em all'.

First, I am using a separate database named 'util' for my helper stored procedures. The code of my stored procedure to truncate all tables is:

DROP PROCEDURE IF EXISTS trunctables;
DELIMITER ;;
CREATE  PROCEDURE trunctables(theDb varchar(64))
BEGIN
    declare tname varchar(64);
    declare tcursor CURSOR FOR 
    SELECT table_name FROM information_schema.tables WHERE table_type <> 'VIEW' AND table_schema = theDb;
    SET FOREIGN_KEY_CHECKS = 0; 
    OPEN tcursor;
    l1: LOOP
        FETCH tcursor INTO tname;
        if tname = NULL then leave l1; end if;
        set @sql = CONCAT('truncate `', theDB, '`.`', tname, '`');
        PREPARE stmt from @sql;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;
    END LOOP l1;
    CLOSE tcursor;
    SET FOREIGN_KEY_CHECKS = 1; 
END ;;
DELIMITER ;

Once you have this stored procedure in your util database, you can call it like

call util.trunctables('nameofdatabase');

which is now exactly one statement :-)

Use (on Linux): cd android ./gradlew assemblyRelease|assemblyDebug

An unsigned APK is generated for each case (for debug or testing)

NOTE: On Windows, replace gradle executable for gradlew.bat

You can create an object of key/value pairs and jQuery will do the rest for you:

$.ajax({
    ...
    data : { foo : 'bar', bar : 'foo' },
    ...
});

This way the data will be properly encoded automatically. If you do want to concoct you own string then make sure to use encodeURIComponent(): https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/encodeURIComponent

Your current code is not working because the string is not concocted properly:

'id='+ id  & 'name='+ name

should be:

'id='+ encodeURIComponent(id) + '&name='+ encodeURIComponent(name)

The reason is because a FileStream is returned from your method to create a file. You should return the FileStream into a variable or call the close method directly from it after the File.Create.

It is a best practice to let the using block help you implement the IDispose pattern for a task like this. Perhaps what might work better would be:

if(!File.Exists(myPath)){
   using(FileStream fs = File.Create(myPath))
   using(StreamWriter writer = new StreamWriter(fs)){
      // do your work here
   }
}

The params parameter modifier gives callers a shortcut syntax for passing multiple arguments to a method. There are two ways to call a method with a params parameter:

1) Calling with an array of the parameter type, in which case the params keyword has no effect and the array is passed directly to the method:

object[] array = new[] { "1", "2" };

// Foo receives the 'array' argument directly.
Foo( array );

2) Or, calling with an extended list of arguments, in which case the compiler will automatically wrap the list of arguments in a temporary array and pass that to the method:

// Foo receives a temporary array containing the list of arguments.
Foo( "1", "2" );

// This is equivalent to:
object[] temp = new[] { "1", "2" );
Foo( temp );

In order to pass in an object array to a method with a "params object[]" parameter, you can either:

1) Create a wrapper array manually and pass that directly to the method, as mentioned by lassevk:

Foo( new object[] { array } );  // Equivalent to calling convention 1.

2) Or, cast the argument to object, as mentioned by Adam, in which case the compiler will create the wrapper array for you:

Foo( (object)array );  // Equivalent to calling convention 2.

However, if the goal of the method is to process multiple object arrays, it may be easier to declare it with an explicit "params object[][]" parameter. This would allow you to pass multiple arrays as arguments:

void Foo( params object[][] arrays ) {
  foreach( object[] array in arrays ) {
    // process array
  }
}

...
Foo( new[] { "1", "2" }, new[] { "3", "4" } );

// Equivalent to:
object[][] arrays = new[] {
  new[] { "1", "2" },
  new[] { "3", "4" }
};
Foo( arrays );

Edit: Raymond Chen describes this behavior and how it relates to the C# specification in a new post.

Your [hidden] will work but you need to check the css:

<input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden" />

And the css:

[hidden] {
  display: none !important;
}

That should work as you want.

Like Jaanus told:

Calling this (-selectRowAtIndexPath:animated:scrollPosition:) method does not cause the delegate to receive a tableView:willSelectRowAtIndexPath: or tableView:didSelectRowAtIndexPath: message, nor will it send UITableViewSelectionDidChangeNotification notifications to observers.

So you just have to call the delegate method yourself.

For example:

Swift 3 version:

let indexPath = IndexPath(row: 0, section: 0);
self.tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)
self.tableView(self.tableView, didSelectRowAt: indexPath)

ObjectiveC version:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView selectRowAtIndexPath:indexPath 
                            animated:YES 
                      scrollPosition:UITableViewScrollPositionNone];
[self tableView:self.tableView didSelectRowAtIndexPath:indexPath];

Swift 2.3 version:

 let indexPath = NSIndexPath(forRow: 0, inSection: 0);
 self.tableView.selectRowAtIndexPath(indexPath, animated: false, scrollPosition: UITableViewScrollPosition.None)
 self.tableView(self.tableView, didSelectRowAtIndexPath: indexPath)

For bootstrap datetimepicker, assign decade value as follow:

$(".years").datetimepicker({
    format: "yyyy",
    startView: 'decade',
    minView: 'decade',
    viewSelect: 'decade',
    autoclose: true,
});

Using jQuery it's quite trivial. v2.0 uses the table class on all tables.

$('.table > tbody > tr').click(function() {
    // row was clicked
});

There's some good answers here already, but I thought I might mention that pdftk might be useful for this task. Instead of producing one PDF directly, you could produce each PDF you need and then combine them together as a post-process with pdftk. This could even be done from within your program using a system() or ShellExecute() call.

for image write this

<input type=file accept="image/*">

For other, You can use the accept attribute on your form to suggest to the browser to restrict certain types. However, you'll want to re-validate in your server-side code to make sure. Never trust what the client sends you

You can also do a simple check using function,

$scope.isNullOrEmptyOrUndefined = function (value) {
    return !value;
}

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.

Option #1 (Markdown code-blocks)

Discord supports Markdown and uses highlight.js to highlight code-blocks. Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.

To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).

```language
message
```

Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).

Option #2 (Embeds)

Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

(Embed Cheat-sheet)

Sure you can use isinstance, but be aware that this is not how Python works. Python is a duck typed language. You should not explicitly check your types. A TypeError will be raised if the incorrect type was passed.

So just assume it is an int. Don't bother checking.

A workaround of mine is to manipulate a model variable just for the ng-class toggling:

For example, I want to toggle class according to the state of my list:

1) Whenever my list is empty, I update my model:

$scope.extract = function(removeItemId) {
    $scope.list= jQuery.grep($scope.list, function(item){return item.id != removeItemId});
    if (!$scope.list.length) {
        $scope.liststate = "empty";
    }
}

2) Whenever my list is not empty, I set another state

$scope.extract = function(item) {
    $scope.list.push(item);
    $scope.liststate = "notempty";
}

3) When my list is not ever touched, I want to give another class (this is where the page is initiated):

$scope.liststate = "init";

3) I use this additional model on my ng-class:

ng-class="{'bg-empty': liststate == 'empty', 'bg-notempty': liststate == 'notempty', 'bg-init': liststate = 'init'}"

To stop further execution when command fails:

command || exit 0

To continue execution when command fails:

command || true

Here is the simplest solution.

Before I start, I must tell you dropdown select box will automatically expand in almost all the browsers except IE6. So, I would do a browser check (i.e., IE6) and write the following only to that browser. Here it goes. First check for the browser.

The code will magically expands the dropdown select box. The only problem with the solution is onmouseover the dropdown will be expanded to 420px, and because the overflow = hidden we are hiding the expanded dropdown size and showing it as 170px; so, the arrow at the right side of the ddl will be hidden and cannot be seen. but the select box will be expanded to 420px; which is what we really want. Just try the code below for yourself and use it if you like it.

.ctrDropDown
{
    width:420px; <%--this is the actual width of the dropdown list--%>
}
.ctrDropDownClick
{
    width:420px; <%-- this the width of the dropdown select box.--%>
}

<div style="width:170px; overflow:hidden;">
<asp:DropDownList runat="server" ID="ddlApplication" onmouseout = "this.className='ctrDropDown';" onmouseover ="this.className='ctrDropDownClick';" class="ctrDropDown" onBlur="this.className='ctrDropDown';" onMouseDown="this.className='ctrDropDownClick';" onChange="this.className='ctrDropDown';"></asp:DropDownList>
</div>

The above is the IE6 CSS. The common CSS for all other browsers should be as below.

.ctrDropDown
{
    width:170px; <%--this is the actual width of the dropdown list--%>
}
.ctrDropDownClick
{
    width:auto; <%-- this the width of the dropdown select box.--%>
}

If you're getting source in Content Use the following method

try
{
    var response = restClient.Execute<List<EmpModel>>(restRequest);

    var jsonContent = response.Content;

    var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);

    foreach (EmpModel item in data)
    {
        listPassingData?.Add(item);
    }
}
catch (Exception ex)
{
    Console.WriteLine($"Data get mathod problem {ex} ");
}

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

If you are binding a List

List<Student> student = new List<Student>();

dataGridView1.DataSource = student.ToList();
student .Add(new Student());

//Reset the Datasource
dataGridView1.DataSource = null;
dataGridView1.DataSource = student;

If you are binding DataTable

DataTable table = new DataTable();

 DataRow newRow = table.NewRow();

// Add the row to the rows collection.
table.Rows.Add(newRow);

I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).

e.g. (from the doc)

     System.out.println("<< Response: " + response.getStatusLine());
     System.out.println(EntityUtils.toString(response.getEntity()));

If you will still use JCrop, you will need only this php functions to crop the file:

$img_src = imagecreatefromjpeg($src);
$img_dest = imagecreatetruecolor($new_w,$new_h);
imagecopyresampled($img_dest,$img_src,0,0,$x,$y,$new_w,$new_h,$w,$h);
imagejpeg($img_dest,$dest);

client side:

jQuery(function($){

    $('#target').Jcrop({
    onChange:   showCoords,
    onSelect:   showCoords,
    onRelease:  clearCoords
    });

});

var x,y,w,h; //these variables are necessary to crop
function showCoords(c)
{
    x = c.x;
    y = c.y;
    w = c.w;
    h = c.h;
};
function clearCoords()
{
    x=y=w=h=0;
}

Setup 1: compile your own glibc without dedicated GCC and use it

Since it seems impossible to do just with symbol versioning hacks, let's go one step further and compile glibc ourselves.

This setup might work and is quick as it does not recompile the whole GCC toolchain, just glibc.

But it is not reliable as it uses host C runtime objects such as crt1.o, crti.o, and crtn.o provided by glibc. This is mentioned at: https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location Those objects do early setup that glibc relies on, so I wouldn't be surprised if things crashed in wonderful and awesomely subtle ways.

For a more reliable setup, see Setup 2 below.

Build glibc and install locally:

export glibc_install="$(pwd)/glibc/build/install"

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28
mkdir build
cd build
../configure --prefix "$glibc_install"
make -j `nproc`
make install -j `nproc`

Setup 1: verify the build

test_glibc.c

#define _GNU_SOURCE
#include <assert.h>
#include <gnu/libc-version.h>
#include <stdatomic.h>
#include <stdio.h>
#include <threads.h>

atomic_int acnt;
int cnt;

int f(void* thr_data) {
    for(int n = 0; n < 1000; ++n) {
        ++cnt;
        ++acnt;
    }
    return 0;
}

int main(int argc, char **argv) {
    /* Basic library version check. */
    printf("gnu_get_libc_version() = %s\n", gnu_get_libc_version());

    /* Exercise thrd_create from -pthread,
     * which is not present in glibc 2.27 in Ubuntu 18.04.
     * https://stackoverflow.com/questions/56810/how-do-i-start-threads-in-plain-c/52453291#52453291 */
    thrd_t thr[10];
    for(int n = 0; n < 10; ++n)
        thrd_create(&thr[n], f, NULL);
    for(int n = 0; n < 10; ++n)
        thrd_join(thr[n], NULL);
    printf("The atomic counter is %u\n", acnt);
    printf("The non-atomic counter is %u\n", cnt);
}

Compile and run with test_glibc.sh:

#!/usr/bin/env bash
set -eux
gcc \
  -L "${glibc_install}/lib" \
  -I "${glibc_install}/include" \
  -Wl,--rpath="${glibc_install}/lib" \
  -Wl,--dynamic-linker="${glibc_install}/lib/ld-linux-x86-64.so.2" \
  -std=c11 \
  -o test_glibc.out \
  -v \
  test_glibc.c \
  -pthread \
;
ldd ./test_glibc.out
./test_glibc.out

The program outputs the expected:

gnu_get_libc_version() = 2.28
The atomic counter is 10000
The non-atomic counter is 8674

Command adapted from https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location but --sysroot made it fail with:

cannot find /home/ciro/glibc/build/install/lib/libc.so.6 inside /home/ciro/glibc/build/install

so I removed it.

ldd output confirms that the ldd and libraries that we've just built are actually being used as expected:

+ ldd test_glibc.out
        linux-vdso.so.1 (0x00007ffe4bfd3000)
        libpthread.so.0 => /home/ciro/glibc/build/install/lib/libpthread.so.0 (0x00007fc12ed92000)
        libc.so.6 => /home/ciro/glibc/build/install/lib/libc.so.6 (0x00007fc12e9dc000)
        /home/ciro/glibc/build/install/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007fc12f1b3000)

The gcc compilation debug output shows that my host runtime objects were used, which is bad as mentioned previously, but I don't know how to work around it, e.g. it contains:

COLLECT_GCC_OPTIONS=/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/crt1.o

Setup 1: modify glibc

Now let's modify glibc with:

diff --git a/nptl/thrd_create.c b/nptl/thrd_create.c
index 113ba0d93e..b00f088abb 100644
--- a/nptl/thrd_create.c
+++ b/nptl/thrd_create.c
@@ -16,11 +16,14 @@
    License along with the GNU C Library; if not, see
    <http://www.gnu.org/licenses/>.  */

+#include <stdio.h>
+
 #include "thrd_priv.h"

 int
 thrd_create (thrd_t *thr, thrd_start_t func, void *arg)
 {
+  puts("hacked");
   _Static_assert (sizeof (thr) == sizeof (pthread_t),
                   "sizeof (thr) != sizeof (pthread_t)");

Then recompile and re-install glibc, and recompile and re-run our program:

cd glibc/build
make -j `nproc`
make -j `nproc` install
./test_glibc.sh

and we see hacked printed a few times as expected.

This further confirms that we actually used the glibc that we compiled and not the host one.

Tested on Ubuntu 18.04.

Setup 2: crosstool-NG pristine setup

This is an alternative to setup 1, and it is the most correct setup I've achieved far: everything is correct as far as I can observe, including the C runtime objects such as crt1.o, crti.o, and crtn.o.

In this setup, we will compile a full dedicated GCC toolchain that uses the glibc that we want.

The only downside to this method is that the build will take longer. But I wouldn't risk a production setup with anything less.

crosstool-NG is a set of scripts that downloads and compiles everything from source for us, including GCC, glibc and binutils.

Yes the GCC build system is so bad that we need a separate project for that.

This setup is only not perfect because crosstool-NG does not support building the executables without extra -Wl flags, which feels weird since we've built GCC itself. But everything seems to work, so this is only an inconvenience.

Get crosstool-NG and configure it:

git clone https://github.com/crosstool-ng/crosstool-ng
cd crosstool-ng
git checkout a6580b8e8b55345a5a342b5bd96e42c83e640ac5
export CT_PREFIX="$(pwd)/.build/install"
export PATH="/usr/lib/ccache:${PATH}"
./bootstrap
./configure --enable-local
make -j `nproc`
./ct-ng x86_64-unknown-linux-gnu
./ct-ng menuconfig

The only mandatory option that I can see, is making it match your host kernel version to use the correct kernel headers. Find your host kernel version with:

uname -a

which shows me:

4.15.0-34-generic

so in menuconfig I do:

• Operating System
  • Version of linux

so I select:

4.14.71

which is the first equal or older version. It has to be older since the kernel is backwards compatible.

Now you can build with:

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

and now wait for about thirty minutes to two hours for compilation.

Setup 2: optional configurations

The .config that we generated with ./ct-ng x86_64-unknown-linux-gnu has:

CT_GLIBC_V_2_27=y

To change that, in menuconfig do:

• C-library
• Version of glibc

save the .config, and continue with the build.

Or, if you want to use your own glibc source, e.g. to use glibc from the latest git, proceed like this:

• Paths and misc options
  • Try features marked as EXPERIMENTAL: set to true
• C-library
  • Source of glibc
    • Custom location: say yes
    • Custom location
      • Custom source location: point to a directory containing your glibc source

where glibc was cloned as:

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28

Setup 2: test it out

Once you have built he toolchain that you want, test it out with:

#!/usr/bin/env bash
set -eux
install_dir="${CT_PREFIX}/x86_64-unknown-linux-gnu"
PATH="${PATH}:${install_dir}/bin" \
  x86_64-unknown-linux-gnu-gcc \
  -Wl,--dynamic-linker="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib/ld-linux-x86-64.so.2" \
  -Wl,--rpath="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib" \
  -v \
  -o test_glibc.out \
  test_glibc.c \
  -pthread \
;
ldd test_glibc.out
./test_glibc.out

Everything seems to work as in Setup 1, except that now the correct runtime objects were used:

COLLECT_GCC_OPTIONS=/home/ciro/crosstool-ng/.build/install/x86_64-unknown-linux-gnu/bin/../x86_64-unknown-linux-gnu/sysroot/usr/lib/../lib64/crt1.o

Setup 2: failed efficient glibc recompilation attempt

It does not seem possible with crosstool-NG, as explained below.

If you just re-build;

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

then your changes to the custom glibc source location are taken into account, but it builds everything from scratch, making it unusable for iterative development.

If we do:

./ct-ng list-steps

it gives a nice overview of the build steps:

Available build steps, in order:
  - companion_tools_for_build
  - companion_libs_for_build
  - binutils_for_build
  - companion_tools_for_host
  - companion_libs_for_host
  - binutils_for_host
  - cc_core_pass_1
  - kernel_headers
  - libc_start_files
  - cc_core_pass_2
  - libc
  - cc_for_build
  - cc_for_host
  - libc_post_cc
  - companion_libs_for_target
  - binutils_for_target
  - debug
  - test_suite
  - finish
Use "<step>" as action to execute only that step.
Use "+<step>" as action to execute up to that step.
Use "<step>+" as action to execute from that step onward.

therefore, we see that there are glibc steps intertwined with several GCC steps, most notably libc_start_files comes before cc_core_pass_2, which is likely the most expensive step together with cc_core_pass_1.

In order to build just one step, you must first set the "Save intermediate steps" in .config option for the intial build:

• Paths and misc options
  • Debug crosstool-NG
    • Save intermediate steps

and then you can try:

env -u LD_LIBRARY_PATH time ./ct-ng libc+ -j`nproc`

but unfortunately, the + required as mentioned at: https://github.com/crosstool-ng/crosstool-ng/issues/1033#issuecomment-424877536

Note however that restarting at an intermediate step resets the installation directory to the state it had during that step. I.e., you will have a rebuilt libc - but no final compiler built with this libc (and hence, no compiler libraries like libstdc++ either).

and basically still makes the rebuild too slow to be feasible for development, and I don't see how to overcome this without patching crosstool-NG.

Furthermore, starting from the libc step didn't seem to copy over the source again from Custom source location, further making this method unusable.

Bonus: stdlibc++

A bonus if you're also interested in the C++ standard library: How to edit and re-build the GCC libstdc++ C++ standard library source?

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

Here's how I do it using a DataTable. This is a working piece of TEST code.

using (SqlConnection con = new SqlConnection(connStr))
{
    con.Open();

    // Create a table with some rows. 
    DataTable table = MakeTable();

    // Get a reference to a single row in the table. 
    DataRow[] rowArray = table.Select();

    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(con))
    {
        bulkCopy.DestinationTableName = "dbo.CarlosBulkTestTable";

        try
        {
            // Write the array of rows to the destination.
            bulkCopy.WriteToServer(rowArray);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

    }

}//using

You can join to the same table on the fields that would be duplicated and then anti-join on the id field. Select the id field from the first table alias (tn1) and then use the array_agg function on the id field of the second table alias. Finally, for the array_agg function to work properly, you will group the results by the tn1.id field. This will produce a result set that contains the the id of a record and an array of all the id's that fit the join conditions.

select tn1.id,
       array_agg(tn2.id) as duplicate_entries, 
from table_name tn1 join table_name tn2 on 
    tn1.year = tn2.year 
    and tn1.sid = tn2.sid 
    and tn1.user_id = tn2.user_id 
    and tn1.cid = tn2.cid
    and tn1.id <> tn2.id
group by tn1.id;

Obviously, id's that will be in the duplicate_entries array for one id, will also have their own entries in the result set. You will have to use this result set to decide which id you want to become the source of 'truth.' The one record that shouldn't get deleted. Maybe you could do something like this:

with dupe_set as (
select tn1.id,
       array_agg(tn2.id) as duplicate_entries, 
from table_name tn1 join table_name tn2 on 
    tn1.year = tn2.year 
    and tn1.sid = tn2.sid 
    and tn1.user_id = tn2.user_id 
    and tn1.cid = tn2.cid
    and tn1.id <> tn2.id
group by tn1.id
order by tn1.id asc)
select ds.id from dupe_set ds where not exists 
 (select de from unnest(ds.duplicate_entries) as de where de < ds.id)

Selects the lowest number ID's that have duplicates (assuming the ID is increasing int PK). These would be the ID's that you would keep around.

If you can't change the datatype on the table itself to use varchar(max), then change your query to this:

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR(MAX), [CastleType]) = 'foo'

SyncToy is a free application from Microsoft with a "Preview" mode for comparing two paths. For example:

You can then choose one of three modes ("Synchronize", "Echo" and "Contribute") to resolve the differences.

Lastly, it comes with SyncToyCmd for creating and synchronizing folder pairs from the CLI or a Scheduled Task.

As of Node.js 14.3.0 the top-level await is supported.

I needed this for something as simple as redirecting all http traffic from the default apache home page on my server to one served over https.

Since I'm still quite green when it comes to configuring apache, I prefer to avoid using mod_rewrite directly and instead went for something simpler like this:

<VirtualHost *:80>
  <Location "/">
     Redirect permanent "https://%{HTTP_HOST}%{REQUEST_URI}"
  </Location>
</VirtualHost>

<VirtualHost *:443>
  DocumentRoot "/var/www/html"
  SSLEngine on
  ...
</VirtualHost>

I like this because it allowed me to use apache variables and that way I didn't have to specify the actual host name since it's just an IP address without an associated domain name.

Simple like a piece of CAKE!

You can define a new column type like (L in this case) while maintaining the current alignment (c, r or l):

\documentclass{article}
\usepackage{array}
\newcolumntype{L}{>{\centering\arraybackslash}m{3cm}}

\begin{document}

\begin{table}
    \begin{tabular}{|c|L|L|}
        \hline
        Title 1 & Title 2 & Title 3 \\
        \hline 
        one-liner & multi-line and centered & \multicolumn{1}{m{3cm}|}{multi-line piece of text to show case a multi-line and justified cell}   \\
        \hline
        apple & orange & banana \\
        \hline
        apple & orange & banana \\
        \hline
    \end{tabular}
\end{table}
\end{document}

The literal 0 has two meanings in C++.
On the one hand, it is an integer with the value 0.
On the other hand, it is a null-pointer constant.

As your setval function can accept either an int or a char*, the compiler can not decide which overload you meant.

The easiest solution is to just cast the 0 to the right type.
Another option is to ensure the int overload is preferred, for example by making the other one a template:

class huge
{
 private:
  unsigned char data[BYTES];
 public:
  void setval(unsigned int);
  template <class T> void setval(const T *); // not implemented
  template <> void setval(const char*);
};

You can find <div> by id, look at it's style.display property and toggle it from none to block and vice versa.

function showDiv(Div) {_x000D_
    var x = document.getElementById(Div);_x000D_
    if(x.style.display=="none") {_x000D_
        x.style.display = "block";_x000D_
    } else {_x000D_
        x.style.display = "none";_x000D_
    }_x000D_
}

<div id="welcomeDiv" style="display:none;" class="answer_list">WELCOME</div>_x000D_
<input type="button" name="answer" value="Show Div" onclick="showDiv('welcomeDiv')" />

The division operator is /, not \

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

The following reads a file passed as an argument line by line:

while IFS= read -r line; do
    echo "Text read from file: $line"
done < my_filename.txt

This is the standard form for reading lines from a file in a loop. Explanation:

• IFS= (or IFS='') prevents leading/trailing whitespace from being trimmed.
• -r prevents backslash escapes from being interpreted.

Or you can put it in a bash file helper script, example contents:

#!/bin/bash
while IFS= read -r line; do
    echo "Text read from file: $line"
done < "$1"

If the above is saved to a script with filename readfile, it can be run as follows:

chmod +x readfile
./readfile filename.txt

If the file isn’t a standard POSIX text file (= not terminated by a newline character), the loop can be modified to handle trailing partial lines:

while IFS= read -r line || [[ -n "$line" ]]; do
    echo "Text read from file: $line"
done < "$1"

Here, || [[ -n $line ]] prevents the last line from being ignored if it doesn't end with a \n (since read returns a non-zero exit code when it encounters EOF).

If the commands inside the loop also read from standard input, the file descriptor used by read can be chanced to something else (avoid the standard file descriptors), e.g.:

while IFS= read -r -u3 line; do
    echo "Text read from file: $line"
done 3< "$1"

(Non-Bash shells might not know read -u3; use read <&3 instead.)

for specific tag name

$ docker images  --filter reference='<REPOSITORY>:TAG'

for "like clause" tagname:my_image_tag --> start my_ima*

$ docker images  --filter reference='<REPOSITORY>:my_ima*'

if you want to someting "the image" for example delete all images tag started "my_ima" try this

docker rmi -f $(docker images -q  --filter reference='myreponame:my_ima*')

I got it to work with

@Html.EditorFor(model => model.Foo) 

and then making a file at Views/Shared/EditorTemplates/Boolean.cshtml with the following:

@model bool?

@Html.CheckBox("", Model.GetValueOrDefault())

A simple workaround:

config.js

export default
{
  // my json here...
}

then...

import config from '../config.js'

does not allow import of existing .json files, but does a job.

See the git-pull man page:

git pull [options] [<repository> [<refspec>...]]

and in the examples section:

Merge into the current branch the remote branch next:

$ git pull origin next

So I imagine you want to do something like:

git pull origin dev

To set it up so that it does this by default while you're on the dev branch:

git branch --set-upstream-to dev origin/dev

I had enough success just catchig socket.timeout and socket.error; although socket.error can be raised for lots of reasons. Be careful.

import socket
import logging

hostname='google.com'
port=443

try:
    sock = socket.create_connection((hostname, port), timeout=3)

except socket.timeout as err:
    logging.error(err)

except socket.error as err:
    logging.error(err)

Jerry's answer is great. However, it doesn't handle large responses. A simple change to handle this:

memset(response, 0, sizeof(response));
total = sizeof(response)-1;
received = 0;
do {
    printf("RESPONSE: %s\n", response);
    // HANDLE RESPONSE CHUCK HERE BY, FOR EXAMPLE, SAVING TO A FILE.
    memset(response, 0, sizeof(response));
    bytes = recv(sockfd, response, 1024, 0);
    if (bytes < 0)
        printf("ERROR reading response from socket");
    if (bytes == 0)
        break;
    received+=bytes;
} while (1); 

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

intutils.ToFloat32

// ToFloat32 converts a int num to a float32 num
func ToFloat32(in int) float32 {
    return float32(in)
}

// ToFloat64 converts a int num to a float64 num
func ToFloat64(in int) float64 {
    return float64(in)
}

You also can use:

element.addEventListener("click", function(){
    // call execute function here...
}, false);

Another solution I've just found here How to render a scaled SVG to a QImage?

from PySide.QtSvg import *
from PySide.QtGui import *


def convertSvgToPng(svgFilepath,pngFilepath,width):
    r=QSvgRenderer(svgFilepath)
    height=r.defaultSize().height()*width/r.defaultSize().width()
    i=QImage(width,height,QImage.Format_ARGB32)
    p=QPainter(i)
    r.render(p)
    i.save(pngFilepath)
    p.end()

PySide is easily installed from a binary package in Windows (and I use it for other things so is easy for me).

However, I noticed a few problems when converting country flags from Wikimedia, so perhaps not the most robust svg parser/renderer.

If your components are global you can simply do:

var nameOfComponent = "SomeComponent";_x000D_
React.createElement(window[nameOfComponent], {});

This one works for me, I first try to get UTC time, and then add or subtract hours according to the timezone you'd like to set.

today = datetime.utcnow()

ES6

With the new class and extend keywords it’s now much easier:

class CustomError extends Error {
  constructor(message) {
    super(message);
    //something
  }
}

In addition to install the build tools and restart the update manager I also had to restart Eclipse to make this work.

I'd like to point out that one issues is what if the same resources are in multiple jar files. Let's say you want to read /org/node/foo.txt, but not from one file, but from each and every jar file.

I have run into this same issue several times before. I was hoping in JDK 7 that someone would write a classpath filesystem, but alas not yet.

Spring has the Resource class which allows you to load classpath resources quite nicely.

I wrote a little prototype to solve this very problem of reading resources form multiple jar files. The prototype does not handle every edge case, but it does handle looking for resources in directories that are in the jar files.

I have used Stack Overflow for quite sometime. This is the second answer that I remember answering a question so forgive me if I go too long (it is my nature).

This is a prototype resource reader. The prototype is devoid of robust error checking.

I have two prototype jar files that I have setup.

 <pre>
         <dependency>
              <groupId>invoke</groupId>
              <artifactId>invoke</artifactId>
              <version>1.0-SNAPSHOT</version>
          </dependency>

          <dependency>
               <groupId>node</groupId>
               <artifactId>node</artifactId>
               <version>1.0-SNAPSHOT</version>
          </dependency>

The jar files each have a file under /org/node/ called resource.txt.

This is just a prototype of what a handler would look like with classpath:// I also have a resource.foo.txt in my local resources for this project.

It picks them all up and prints them out.

   

    package com.foo;

    import java.io.File;
    import java.io.FileReader;

You can see a fuller example here with the sample output.

Incrementing a variable can be done like that:

  _my_counter=$[$_my_counter + 1]

Counting the number of occurrence of a pattern in a column can be done with grep

 grep -cE "^([^ ]* ){2}US"

-c count

([^ ]* ) To detect a colonne

{2} the colonne number

US your pattern

In your Manifest you need to reference the name of the style that has the text color item inside it. Right now you are just referencing an empty style. So in your theme.xml do only this style:

<style name="Theme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
</style>

And keep you reference to in the Manifest the same (android:theme="@style/Theme")

EDIT:

theme.xml:

<style name="MyTheme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
    <item name="android:textSize">12dp</item>
</style>

Manifest:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">

Notice I combine the text color and size into the same style. Also, I changed the name of the theme to MyTheme and am now referencing that in the Manifest. And I changed to @android:style/TextAppearance for the parent value.

you are doing it wrong, you have first split the string using space as a delimiter using String.split() and populate the char array with charcters.

or even simpler just use String.charAt() in the loop to populate array like below:

String ini="Hi there";
  char[] array=new  char[ini.length()];

  for(int count=0;count<array.length;count++){
         array[count] = ini.charAt(count);
  System.out.print(" "+array[count]);
  }

or one liner would be

  String ini="Hi there";
  char[] array=ini.toCharArray();

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

This seems to work well for me. Tested on Touchwiz 5.1, LineageOS 7.1, and CyanogenMod 11.

RUn the following query to find if you are running spfile or not:

SELECT DECODE(value, NULL, 'PFILE', 'SPFILE') "Init File Type" 
       FROM sys.v_$parameter WHERE name = 'spfile';

If the result is "SPFILE", then use the following command:

alter system set open_cursors = 4000 scope=both; --4000 is the number of open cursor

if the result is "PFILE", then use the following command:

alter system set open_cursors = 1000 ;

You can read about SPFILE vs PFILE here,

Pandas has now got a much more gentle solution, try it:

df[column].idxmax()

For R code I use

\usepackage{listings}
\lstset{
language=R,
basicstyle=\scriptsize\ttfamily,
commentstyle=\ttfamily\color{gray},
numbers=left,
numberstyle=\ttfamily\color{gray}\footnotesize,
stepnumber=1,
numbersep=5pt,
backgroundcolor=\color{white},
showspaces=false,
showstringspaces=false,
showtabs=false,
frame=single,
tabsize=2,
captionpos=b,
breaklines=true,
breakatwhitespace=false,
title=\lstname,
escapeinside={},
keywordstyle={},
morekeywords={}
}

And it looks exactly like this

This is a good summary I found:

The Carriage Return (CR) character (0x0D, \r) moves the cursor to the beginning of the line without advancing to the next line. This character is used as a new line character in Commodore and Early Macintosh operating systems (OS-9 and earlier).

The Line Feed (LF) character (0x0A, \n) moves the cursor down to the next line without returning to the beginning of the line. This character is used as a new line character in UNIX based systems (Linux, Mac OSX, etc)

The End of Line (EOL) sequence (0x0D 0x0A, \r\n) is actually two ASCII characters, a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as a new line character in most other non-Unix operating systems including Microsoft Windows, Symbian OS and others.

When compiling your program, you need to include dict.c as well, eg:

gcc -o test1 test1.c dict.c

Plus you have a typo in dict.c definition of CreateDictionary, it says CreateDectionary (e instead of i)

A callable piece of code (routine) can be a Sub (called for a side effect/what it does) or a Function (called for its return value) or a mixture of both. As the docs for MsgBox

Displays a message in a dialog box, waits for the user to click a button, and returns a value indicating which button the user clicked.

MsgBox(prompt[, buttons][, title][, helpfile, context])

indicate, this routine is of the third kind.

The syntactical rules of VBScript are simple:

Use parameter list () when calling a (routine as a) Function

If you want to display a message to the user and need to know the user's reponse:

Dim MyVar
MyVar = MsgBox ("Hello World!", 65, "MsgBox Example")
   ' MyVar contains either 1 or 2, depending on which button is clicked.

Don't use parameter list () when calling a (routine as a) Sub

If you want to display a message to the user and are not interested in the response:

MsgBox "Hello World!", 65, "MsgBox Example"

This beautiful simplicity is messed up by:

The design flaw of using () for parameter lists and to force call-by-value semantics

>> Sub S(n) : n = n + 1 : End Sub
>> n = 1
>> S n
>> WScript.Echo n
>> S (n)
>> WScript.Echo n
>>
2
2

S (n) does not mean "call S with n", but "call S with a copy of n's value". Programmers seeing that

>> s = "value"
>> MsgBox(s)

'works' are in for a suprise when they try:

>> MsgBox(s, 65, "MsgBox Example")
>>
Error Number:       1044
Error Description:  Cannot use parentheses when calling a Sub

The compiler's leniency with regard to empty () in a Sub call. The 'pure' Sub Randomize (called for the side effect of setting the random seed) can be called by

Randomize()

although the () can neither mean "give me your return value) nor "pass something by value". A bit more strictness here would force prgrammers to be aware of the difference in

Randomize n

and

Randomize (n)

The Call statement that allows parameter list () in Sub calls:

s = "value" Call MsgBox(s, 65, "MsgBox Example")

which further encourage programmers to use () without thinking.

(Based on What do you mean "cannot use parentheses?")

The Java heap size limits for Windows are:

• maximum possible heap size on 32-bit Java: 1.8 GB
• recommended heap size limit on 32-bit Java: 1.5 GB (or 1.8 GB with /3GB option)

This doesn't help you getting a bigger Java heap, but now you know you can't go beyond these values.

It is rule of thumb that the first layer in your network should be the same shape as your data. For example our data is 28x28 images, and 28 layers of 28 neurons would be infeasible, so it makes more sense to 'flatten' that 28,28 into a 784x1. Instead of wriitng all the code to handle that ourselves, we add the Flatten() layer at the begining, and when the arrays are loaded into the model later, they'll automatically be flattened for us.

var pause_menu = {
    pause_button : { someProperty : "prop1", someOther : "prop2" },
    resume_button : { resumeProp : "prop", resumeProp2 : false },
    quit_button : false
};

then:

pause_menu.pause_button.someProperty //evaluates to "prop1"

etc etc.

I agree with sunetos that you'll have to use the $.ajax function in order to pass request headers. In order to do that, you'll have to write a function for the beforeSend event handler, which is one of the $.ajax() options. Here's a quick sample on how to do that:

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        $.ajax({
          url: 'service.svc/Request',
          type: 'GET',
          dataType: 'json',
          success: function() { alert('hello!'); },
          error: function() { alert('boo!'); },
          beforeSend: setHeader
        });
      });

      function setHeader(xhr) {
        xhr.setRequestHeader('securityCode', 'Foo');
        xhr.setRequestHeader('passkey', 'Bar');
      }
    </script>
  </head>
  <body>
    <h1>Some Text</h1>
  </body>
</html>

If you run the code above and watch the traffic in a tool like Fiddler, you'll see two requests headers passed in:

• securityCode with a value of Foo
• passkey with a value of Bar

The setHeader function could also be inline in the $.ajax options, but I wanted to call it out.

Hope this helps!

Usual python3 log manager works for me with tensorflow==1.11.0:

I was in the same boat. Installed Eclipse, realized need CDT.

sudo apt-get install eclipse eclipse-cdt g++

This just adds the CDT package on top of existing installation - no un-installation etc. required.

To change vector image color you can directly use android:tint="@color/colorAccent"

<ImageView
        android:id="@+id/ivVectorImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_account_circle_black_24dp"
        android:tint="@color/colorAccent" />

To change color programatically

ImageView ivVectorImage = (ImageView) findViewById(R.id.ivVectorImage);
ivVectorImage.setColorFilter(getResources().getColor(R.color.colorPrimary));

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

You should add one rule and add your env:

{
  "rules": {
    "no-console": "off"
  },
  "env": {
    "browser": true
  }
}

you can add other envs.

As to me, you can first(find version.hpp the version variable is in it, if you know where it is(in ubuntu it usually in /usr/include/boost/version.hpp by default install)):

 locate `boost/version.hpp`

Second show it's version by:

 grep BOOST_LIB_VERSION /usr/include/boost/version.hpp

or

  grep BOOST_VERSION /usr/include/boost/version.hpp.

As to me, I have two version boost installed in my system. Output as below:

xy@xy:~$ locate boost/version.hpp |grep boost

/home/xy/boost_install/boost_1_61_0/boost/version.hpp
/home/xy/boost_install/lib/include/boost/version.hpp
/usr/include/boost/version.hpp

xy@xy:~$ grep BOOST_VERSION /usr/include/boost/version.hpp
#ifndef BOOST_VERSION_HPP
#define BOOST_VERSION_HPP
//  BOOST_VERSION % 100 is the patch level
//  BOOST_VERSION / 100 % 1000 is the minor version
//  BOOST_VERSION / 100000 is the major version
#define BOOST_VERSION 105800
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION

# or this way more readable
xy@xy:~$ grep BOOST_LIB_VERSION /usr/include/boost/version.hpp
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_58"

Show local installed version:

xy@xy:~$ grep BOOST_LIB_VERSION /home/xy/boost_install/lib/include/boost/version.hpp
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_61"

If you've checked all the things from the above answers (which are common mistakes) and you're sure that your view is at the location in the exceptions, then you may need to restart Visual Studio.

The argument associated with the %n will be treated as an int* and is filled with the number of total characters printed at that point in the printf.

For Linux and I believe Mac OS X, if you're using gcc, or any compiler that uses glibc, you can use the backtrace() functions in execinfo.h to print a stacktrace and exit gracefully when you get a segmentation fault. Documentation can be found in the libc manual.

Here's an example program that installs a SIGSEGV handler and prints a stacktrace to stderr when it segfaults. The baz() function here causes the segfault that triggers the handler:

#include <stdio.h>
#include <execinfo.h>
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>


void handler(int sig) {
  void *array[10];
  size_t size;

  // get void*'s for all entries on the stack
  size = backtrace(array, 10);

  // print out all the frames to stderr
  fprintf(stderr, "Error: signal %d:\n", sig);
  backtrace_symbols_fd(array, size, STDERR_FILENO);
  exit(1);
}

void baz() {
 int *foo = (int*)-1; // make a bad pointer
  printf("%d\n", *foo);       // causes segfault
}

void bar() { baz(); }
void foo() { bar(); }


int main(int argc, char **argv) {
  signal(SIGSEGV, handler);   // install our handler
  foo(); // this will call foo, bar, and baz.  baz segfaults.
}

Compiling with -g -rdynamic gets you symbol info in your output, which glibc can use to make a nice stacktrace:

$ gcc -g -rdynamic ./test.c -o test

Executing this gets you this output:

$ ./test
Error: signal 11:
./test(handler+0x19)[0x400911]
/lib64/tls/libc.so.6[0x3a9b92e380]
./test(baz+0x14)[0x400962]
./test(bar+0xe)[0x400983]
./test(foo+0xe)[0x400993]
./test(main+0x28)[0x4009bd]
/lib64/tls/libc.so.6(__libc_start_main+0xdb)[0x3a9b91c4bb]
./test[0x40086a]

This shows the load module, offset, and function that each frame in the stack came from. Here you can see the signal handler on top of the stack, and the libc functions before main in addition to main, foo, bar, and baz.

Use git reflog to find the hashes of previously checked out commits.

A shortcut command to get to your last checked out branch (not sure if this work correctly with detached HEAD and intermediate commits though) is git checkout -

As PPK points out here, in IE you can also use

e.cancelBubble = true;

What am I doing incorrectly?

You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.

How can I receive a json object in the controller?

View:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>

var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });

<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>

Controller:

public void PostRawJson(string json)
{
    var order = System.Web.Helpers.Json.Decode(json);
    var orderDate = order.OrderDate;
    var secondOrderId = order.Item[1].Id;
}

General

Single elements of a tuple a can be accessed -in an indexed array-like fashion-

via a[0], a[1], ... depending on the number of elements in the tuple.

Example

If your tuple is a=(3,"a")

• a[0] yields 3,
• a[1] yields "a"

Concrete answer to question

def tup():
  return (3, "hello")

tup() returns a 2-tuple.

In order to "solve"

i = 5 + tup()  # I want to add just the three

you select the 3 by

tup()[0|    #first element

so in total

i = 5 + tup()[0]

Alternatives

Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple

>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

I suppose that 255 in 227./255 is perceived as an integer and divide is always return 0

% ps -o args -C nginx
COMMAND
build/sbin/nginx -c ../test.conf

If nginx was run without the -c option, then you can use the -V option to find out the configure arguments that were set to non-standard values. Among them the most interesting for you are:

--prefix=PATH                      set installation prefix
--sbin-path=PATH                   set nginx binary pathname
--conf-path=PATH                   set nginx.conf pathname

one-liner with streams

Stream.concat(Arrays.stream( array ), Stream.of( newElement )).toArray();

Suppose we have three anchor tags like ,

<a  href="ID=1" class="testClick">Test1.</a>
<br />
<a  href="ID=2" class="testClick">Test2.</a>
<br />
<a  href="ID=3" class="testClick">Test3.</a>

now in script

$(".testClick").click(function () {
        var anchorValue= $(this).attr("href");
        alert(anchorValue);
});

use this keyword instead of className (testClick)

I've gotten the same issue and one of the posted example in the manual worked. A character set must be specified as one of the posters here already mentioned. http://www.php.net/manual/en/function.ob-flush.php#109314

header( 'Content-type: text/html; charset=utf-8' );
echo 'Begin ...<br />';
for( $i = 0 ; $i < 10 ; $i++ )
{
    echo $i . '<br />';
    flush();
    ob_flush();
    sleep(1);
}
echo 'End ...<br />';

If You'd Rather Type A Hostname Instead of IP Address

First Option (Quick Way):

You should be able to navigate to http://my-macbook-pro.local/mywebsite on your iPhone. See https://stackoverflow.com/a/9304094/470749

This approach tends to work because the '.local' domain is a special reserved word.

Second Option:

See http://xip.io/, which is a free service and is super convenient. No config necessary.

Then when you browse to http://mysite.app.192.168.1.130.xip.io (using a browser on your server or on any device on your LAN), it will show the page hosted at 192.168.1.130.

And if you're running Homestead on the machine that exists at that IP, browsing to http://mysite.app.192.168.1.130.xip.io:44300 (with the port in the URL) somehow shows the page hosted on the Homestead Vagrant virtual machine at 192.168.10.10. Pretty amazing.

Third Option (which doesn't depend on a service and is flexible but more complicated and only works if you have a router with DD-WRT on it):

If you have one local server hosting multiple different sites that you'd like to access via different hostnames (via iPhone), you can do this.

1. In your OS, change the name of your computer to something short, meaningful, and easy to remember, such as "RYANDESK".
2. In your DD-WRT router settings:
   1. In Services > Services > Static Leases, set the MAC address of your server to point to a specific IP address, such as 192.168.1.108. Set its hostname to be the same as you named your computer earlier. "Client Lease Time" can be 1440 minutes.
   2. Be sure to press Save and also Apply Settings with every change. ("Save" doesn't seem to automatically apply the settings.) If you get an error, it's probably because the GUI design of DD-WRT is misleading, and you unnecessarily pressed "Add" for Static Leases.
   3. In DHCP Server > User Domain, choose "LAN & WAN". For "LAN Domain", set it to some short string, such as your initials without any punctuation (e.g. "xyz"). Probably avoid using the word "local" since there might be conflicts. Don't use real-world domains such as "com", "org", "net", etc.
3. In Services > Services > DNSMasq, enable DNSMasq and "Local DNS" and configure "Additional DNSMasq Options" to be something like: address=/project1.xyz/project2.xyz/192.168.1.108 (where xyz is whatever you chose in the earlier step, the IP points to the specific machine, and project1 and project2 are whatever hostname you want to point to each of those projects (such as different Nginx configs).
4. Ensure that your HOSTS file doesn't have any entries conflicting with what we've done. If you don't know what a HOSTS file is, you're probably fine.
5. Flush your DNS cache and release and renew your local IP. Switch into and out of Airplane Mode on iPhone to flush DNS cache there too.

6. Now you can browse to http://ryandesk.xyz in your iPhone (or in your desktop browser), and it will resolve to your local server. So hopefully you've set up your Nginx or Apache or whatever to be listening for that hostname.

A transaction isn't needed here, this should suffice:

function add_post($post_data) {
    $this->db->insert('posts',$post_data);
    return $this->db->insert_id();
}

I had a similar problem and none of the solutions above worked, so I went with an old standby that always works:

1. Rename the folder containing the project
2. Make a brand new project with the same name with 2010
3. Diff the two folders and->
4. Copy all source files directly
5. Ignore bin/debug/release etc
6. Diff the .csproj and copy over all lines that are relevant.
7. If the .sln file only has one project, ignore it. If it's complex, then diff it as well.

That almost always works if you've spent 10 minutes at it and can't get it.

Note that for similar problems with older versions (2008, 2005) you can usually get away with just changing the version in the .csproj and either changing the version in the .sln or discarding it, but this doesn't seem to work for 2013.

Using pyautogui

To install

pip install pyautogui

and to find the location of the mouse pointer

import pyautogui
print(pyautogui.position())

This will give the pixel location to which mouse pointer is at.

map isn't particularly pythonic. I would recommend using list comprehensions instead:

map(f, iterable)

is basically equivalent to:

[f(x) for x in iterable]

map on its own can't do a Cartesian product, because the length of its output list is always the same as its input list. You can trivially do a Cartesian product with a list comprehension though:

[(a, b) for a in iterable_a for b in iterable_b]

The syntax is a little confusing -- that's basically equivalent to:

result = []
for a in iterable_a:
    for b in iterable_b:
        result.append((a, b))

if you can use LinqToObjects in your Project

private YourTextBox_TextChanged ( object sender, EventArgs e)
{
   return YourTextBox.Text.Where(c=> c.ToUpper());
}

An if you can't use LINQ (e.g. your project's target FW is .NET Framework 2.0) then

private YourTextBox_TextChanged ( object sender, EventArgs e)
{
   YourTextBox.Text = YourTextBox.Text.ToUpper();
}

Why Text_Changed Event ?

There are few user input events in framework..

1-) OnKeyPressed fires (starts to work) when user presses to a key from keyboard after the key pressed and released

2-) OnKeyDown fires when user presses to a key from keyboard during key presses

3-) OnKeyUp fires when user presses to a key from keyboard and key start to release (user take up his finger from key)

As you see, All three are about keyboard event..So what about if the user copy and paste some data to the textbox?

if you use one of these keyboard events then your code work when and only user uses keyboard..in example if user uses a screen keyboard with mouse click or copy paste the data your code which implemented in keyboard events never fires (never start to work)

so, and Fortunately there is another option to work around : The Text Changed event..

Text Changed event don't care where the data comes from..Even can be a copy-paste, a touchscreen tap (like phones or tablets), a virtual keyboard, a screen keyboard with mouse-clicks (some bank operations use this to much more security, or may be your user would be a disabled person who can't press to a standard keyboard) or a code-injection ;) ..

No Matter !

Text Changed event just care about is there any changes with it's responsibility component area ( here, Your TextBox's Text area) or not..

If there is any change occurs, then your code which implemented under Text changed event works..

well, char * means a pointer point to char, it is different from char array.

char amessage[] = "this is an array";  /* define an array*/
char *pmessage = "this is a pointer"; /* define a pointer*/

And, char ** means a pointer point to a char pointer.

You can look some books about details about pointer and array.

Date is Comparable so just create list of List<Date> and sort it using Collections.sort(). And use Collections.reverseOrder() to get comparator in reverse ordering.

From Java Doc

Returns a comparator that imposes the reverse ordering of the specified comparator. If the specified comparator is null, this method is equivalent to reverseOrder() (in other words, it returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement the Comparable interface).

Use .valid() from the jQuery Validation plugin:

$("#form_id").valid();

Checks whether the selected form is valid or whether all selected elements are valid. validate() needs to be called on the form before checking it using this method.

Where the form with id='form_id' is a form that has already had .validate() called on it.

Try this

link_to "+ Service", my_services_new_path(:account_id => acct.id)

it will pass the account_id as you want.

For more details on link_to use this http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to

try

long diffSeconds = diff / 1000 % 60;  
long diffMinutes = diff / (60 * 1000) % 60; 
long diffHours = diff / (60 * 60 * 1000);

NOTE: this assumes that diff is non-negative.

To add to Alan Wells's elaborate answer here is a quick fix

Run a Local Server

you can serve any folder in your computer with Serve

First, navigate using the command line into the folder you'd like to serve.

Then

npx i -g serve
serve

or if you'd like to test Serve without downloading it

npx serve

and that's it! You can view your files at http://localhost:5000

Please use this on SQL Server 2005:

sp_rename old_table_name , new_table_name

it will give you:

Caution: Changing any part of an object name could break scripts and stored procedures.

but your table name will be changed.

It should be that the particular mvn command execs and does not return, thereby not executing the rest of the commands.

If you have special logic required for the first route only you can do the following:

AppComponent

    loaded = false;

    constructor(private router: Router....) {
       router.events.pipe(filter(e => e instanceof NavigationEnd), take(1))
                    .subscribe((e) => {
                       this.loaded = true;
                       alert('loaded - this fires only once');
                   });

I had a need for this to hide my page footer, which was otherwise appearing at the top of the page. Also if you only want a loader for the first page you can use this.

Perhaps you're looking for the x86_64 ABI?

• www.x86-64.org/documentation/abi.pdf (via Wayback Machine at 2018-11-24)
• Where is the x86-64 System V ABI documented? - https://github.com/hjl-tools/x86-psABI/wiki/X86-psABI is kept up to date (by HJ Lu, one of the ABI maintainers) with links to PDFs of the official current version.

If that's not precisely what you're after, use 'x86_64 abi' in your preferred search engine to find alternative references.

It's very simple. Just Set width of img to 100%

You can simply do this:

System.arraycopy(initialArray, 0, newArray, 0, initialArray.length);

Where $GIT_DIR is the path to the folder to be searched (the git repo path), execute the following in terminal.

find $GIT_DIR -name *.git* -ok rm -Rf {} \;

This will recursively search for any directories or files containing ".git" in the file/directory name within the specified Git directory. This will include .git/ and .gitignore files and any other .git-like assets. The command is interactive and will ask before removing. To proceed with the deletion, simply enter y, then Enter.
