Programs & Examples On #Initializer list

This gives error:

int len;
scanf("%d",&len);
char str[len]="";

This also gives error:

int len=5;
char str[len]="";

But this works fine:

int len=5;
char str[len]; //so the problem lies with assignment not declaration

You need to put value in the following way:

str[0]='a';
str[1]='b'; //like that; and not like str="ab";

1. How can I do what I want to do (that is, initialize an array in a constructor (not assigning elements in the body)). Is it even possible?

Yes. It's using a struct that contains an array. You say you already know about that, but then I don't understand the question. That way, you do initialize an array in the constructor, without assignments in the body. This is what boost::array does.

Does the C++03 standard say anything special about initializing aggregates (including arrays) in ctor initializers? Or the invalidness of the above code is a corollary of some other rules?

A mem-initializer uses direct initialization. And the rules of clause 8 forbid this kind of thing. I'm not exactly sure about the following case, but some compilers do allow it.

struct A {
  char foo[6];
  A():foo("hello") { } /* valid? */
};

See this GCC PR for further details.

Do C++0x initializer lists solve the problem?

Yes, they do. However your syntax is invalid, I think. You have to use braces directly to fire off list initialization

struct A {
  int foo[3];
  A():foo{1, 2, 3} { }
  A():foo({1, 2, 3}) { } /* invalid */
};

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

scanf("%s",str) scans only until it finds a whitespace character. With the input "A 1", it will scan only the first character, hence s2 points at the garbage that happened to be in str, since that array wasn't initialised.

You may try below code...

$(document).ready(function(){_x000D_
    $('form').find('input[type=text],textarea,select').filter(':visible:first').focus();_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>_x000D_
<form>_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
    _x000D_
<input type="submit" />_x000D_
</form>

All of the rules concerning the encoding of URIs (which contains URNs and URLs) are specified in the RFC1738 and the RFC3986, here's a TL;DR of these long and boring documents:

Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a URI under certain circumstances. The characters allowed in a URI are either reserved or unreserved. Reserved characters are those characters that sometimes have special meaning, but they are not the only characters that needs encoding.

There are 66 unreserved characters that doesn't need any encoding: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_.~

There are 18 reserved characters which needs to be encoded: !*'();:@&=+$,/?#[], and all the other characters must be encoded.

To percent-encode a character, simply concatenate "%" and its ASCII value in hexadecimal. The php functions "urlencode" and "rawurlencode" do this job for you.

The guide by Ani Menon (thx!) almost worked for me on windows 10, i just had to get a newer winutils.exe off that git (currently hadoop-2.8.1): https://github.com/steveloughran/winutils

def find_idx(str, ch):
    yield [i for i, c in enumerate(str) if c == ch]

for idx in find_idx('babak karchini is a beginner in python ', 'i'):
    print(idx)

output:

[11, 13, 15, 23, 29]

What you have is on the right track.

def dosomething( thelist ):
    for element in thelist:
        print element

dosomething( ['1','2','3'] )
alist = ['red','green','blue']
dosomething( alist )  

Produces the output:

1
2
3
red
green
blue

A couple of things to note given your comment above: unlike in C-family languages, you often don't need to bother with tracking the index while iterating over a list, unless the index itself is important. If you really do need the index, though, you can use enumerate(list) to get index,element pairs, rather than doing the x in range(len(thelist)) dance.

EDIT:

So which am I supposed to use? The proper 4 letter extension suggested by the creator, or the 3 letter extension found in the wild west of the internet?

This question could be:

1. A request for advice; or

2. A natural expression of that particular emotion which is experienced, while one is observing that some official recommendation is being disregarded—prominently, or even predominantly.

People differ in their predilection for following:

1. Official advice; or

2. The preponderance of practice.

Of course, I am unlikely to influence you, regarding which of these two paths you prefer to take!

In what follows (and, in the spirit of science), I merely make an hypothesis, about what (merely as a matter of fact) led the majority of people to use the 3-letter extension. And, I focus on efficient causes.

By this, I do not intend moral exhortation. As you may recall, the fact that something is, does not imply that it should be.

Whatever your personal inclination, be it to follow one path or the other, I do not object.

(End of edit.)

The suggestion, that this preference (in real life usage) was caused by a 8.3 character DOS-ish limitation, IMO is a red herring (erroneous and misleading).

As of August, 2016, the Google search counts for YML and YAML were approximately 6,000,000 and 4,100,000 (to two digits of precision). Furthermore, the "YAML" count was unfairly high because it included mention of the language by name, beyond its use as an extension.

As of July, 2018, the Google's search counts for YML and YAML were approximately 8,100,000 and 4,100,000 (again, to two digits of precision). So, in the last two years, YML has essentially doubled in popularity, but YAML has stayed the same.

Another cultural measure is websites which attempt to explain file extensions. For example, on the FilExt website (as of July, 2018), the page for YAML results in: "Ooops! The FILEXT.com database does not have any information on file extension .YAML."

Whereas, it has an entry for YML, which gives: "YAML...uses a text file and organizes it into a format which is Human-readable. 'database.yml' is a typical example when YAML is used by Ruby on Rails to connect to a database."

As of November, 2014, Wikipedia's article on extension YML still stated that ".yml" is "the file extension for the YAML file format" (emphasis added). Its YAML article lists both extensions, without expressing a preference.

The extension ".yml" is sufficiently clear, is more brief (thus easier to type and recognize), and is much more common.

Of course, both of these extensions could be viewed as abbreviations of a long, possible extension, ".yamlaintmarkuplanguage". But programmers (and users) don't want to type all of that!

Instead, we programmers (and users) want to type as little as possible, and still yet be unambiguous and clear. And we want to see what kind of file it is, as quickly as possible, without reading a longer word. Typing just how many characters accomplishes both of these goals? Isn't the answer three (3)? In other words, YML?

Wikipedia's Category:Filename_extensions page lists entries for .a, .o and .Z. Somehow, it missed .c and .h (used by the C language). These example single-letter extensions help us to see that extensions should be as long as necessary, but no longer (to half-quote Albert Einstein).

Instead, notice that, in general, few extensions start with "Y". Commonly, on the other hand, the letter X is used for a great variety of meanings including "cross," "extensible," "extreme," "variable," etc. (e.g. in XML). So starting with "Y" already conveys much information (in terms of information theory), whereas starting with "X" does not.

Linguistically speaking, therefore, the acronym "XML" has (in a way) only two informative letters ("M" and "L"). "YML", instead, has three informative letters ("M", "L" and "Y"). Indeed, the existing set of acronyms beginning with Y seems extremely small. By implication, this is why a four letter YAML file extension feels greatly overspecified.

Perhaps this is why we see in practice that the "linguistic" pressure (in natural use) to lengthen the abbreviation in question to four (4) characters is weak, and the "linguistic" pressure to shorten this abbreviation to three (3) characters is strong.

Purely as a result, probably, of these factors (and not as an official endorsement), I would note that the YAML.org website's latest news item (from November, 2011) is all about a project written in JavaScript, JS-YAML, which, itself, internally prefers to use the extension ".yml".

The above-mentioned factors may have been the main ones; nevertheless, all the factors (known or unknown) have resulted in the abbreviated, three (3) character extension becoming the one in predominant use for YAML—despite the inventors' preference.

".YML" seems to be the de facto standard. Yet the same inventors were perceptive and correct, about the world's need for a human-readable data language. And we should thank them for providing it.

Here is what I would use instead, to gracefully handle errors from the script:

"C:\<a long path here>\matlab.exe" -nodisplay -nosplash -nodesktop -r "try, run('C:\<a long path here>\mfile.m'), catch, exit, end, exit"

If you want more verbosity:

"C:\<a long path here>\matlab.exe" -nodisplay -nosplash -nodesktop -r "try, run('C:\<a long path here>\mfile.m'), catch me, fprintf('%s / %s\n',me.identifier,me.message), end, exit"

I found the original reference here. Since original link is now gone, here is the link to an alternate newreader still alive today:

• exit matlab when running batch m file

For those coming across this and looking for performance, it looks like #delete and #tr are about the same in speed and 2-4x faster than gsub.

text = "Here is a string with / some forwa/rd slashes"
tr = Benchmark.measure { 10000.times { text.tr('/', '') } }
# tr.total => 0.01
delete = Benchmark.measure { 10000.times { text.delete('/') } }
# delete.total => 0.01
gsub = Benchmark.measure { 10000.times { text.gsub('/', '') } }
# gsub.total => 0.02 - 0.04

>>> l = range(1,10)

>>> l[:2] + l[3:]

Here is another way to express the object property.

foreach ($obj as $key=>$value) {
    echo "$key => $obj[$key]\n";
}

Use dict.has_key() if (and only if) your code is required to be runnable by Python versions earlier than 2.3 (when key in dict was introduced).

Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit.

You need to set the Identity seed to that value:

CREATE TABLE orders
(
 id int IDENTITY(9586,1)
)

To alter an existing table:

ALTER TABLE orders ALTER COLUMN Id INT IDENTITY (9586, 1);

More info on CREATE TABLE (Transact-SQL) IDENTITY (Property)

convert the NULL values with empty string by wrapping it in COALESCE

"UPDATE table SET data = CONCAT(COALESCE(`data`,''), 'a')"

OR

Use CONCAT_WS instead:

"UPDATE table SET data = CONCAT_WS(',',data, 'a')"

I had been facing a similar issue, unfortunately after implementing all the solutions above, I came to the following conclusion.

1. My inner elements had a fragile CSS structure and implementing a position relative / absolute play, was completely breaking the page design.
2. CSS is not my strong suit.

I wrote this simple scrolling js, that accounts for the offset caused due to the header and relocated the div about 125 pixels below. Please use it as you see fit.

The HTML

<div id="#anchor"></div> <!-- #anchor here is the anchor tag which is on your URL -->

The JavaScript

 $(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
&& location.hostname == this.hostname) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 125 //offsets for fixed header
        }, 1000);
        return false;
      }
    }
  });
  //Executed on page load with URL containing an anchor tag.
  if($(location.href.split("#")[1])) {
      var target = $('#'+location.href.split("#")[1]);
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 125 //offset height of header here too.
        }, 1000);
        return false;
      }
    }
});

Maybe I am missing something here, but did you allocate any memory for that PString before you accessed it?

PString * initializeString() {
    PString *str;
    str = (PString *) malloc(sizeof(PString));
    str->length = &length;
    return str;
}

If you just want a file without revision information use

svn export <URL>

I was not actually able to render an image without borders or axis data based on any of the code snippets here (even the one accepted at the answer). After digging through some API documentation, I landed on this code to render my image

plt.axis('off')
plt.tick_params(axis='both', left='off', top='off', right='off', bottom='off', labelleft='off', labeltop='off', labelright='off', labelbottom='off')
plt.savefig('foo.png', dpi=100, bbox_inches='tight', pad_inches=0.0)

I used the tick_params call to basically shut down any extra information that might be rendered and I have a perfect graph in my output file.

I see there isn't an answer for users of Tornado:

key = self.request.query_arguments.get("key", None)

This method must work inside an handler that is derived from:

tornado.web.RequestHandler

None is the answer this method will return when the requested key can't be found. This saves you some exception handling.

De-structuring Assignment in ES6 would help here.For Ex:

let [arg1, arg2] = new Promise((resolve, reject) => {
    resolve([argument1, argument2]);
});

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

PasswordAuthentication and ChallengeResponseAuthentication default set to NO in rhel7.

There's a library called Zeta Long Paths that provides a .NET API to work with long paths.

Here's a good article that covers this issue for both .NET and PowerShell: ".NET, PowerShell Path too Long Exception and a .NET PowerShell Robocopy Clone"

Using data.frame instead of cbind should be helpful

x <- data.frame(col1=c(10, 20), col2=c("[]", "[]"), col3=c("[[1,2]]","[[1,3]]"))
x
  col1 col2    col3
1   10   [] [[1,2]]
2   20   [] [[1,3]]

sapply(x, class) # looking into x to see the class of each element
     col1      col2      col3 
"numeric"  "factor"  "factor" 

As you can see elements from col1 are numeric as you wish.

data.frame can have variables of different class: numeric, factor and character but matrix doesn't, once you put a character element into a matrix all the other will become into this class no matter what clase they were before.

Yes, an instance variable will be initialized to a default value. For a local variable, you need to initialize before use:

public class Main {

    int instaceVariable; // An instance variable will be initialized to the default value

    public static void main(String[] args) {
        int localVariable = 0; // A local variable needs to be initialized before use
    }
}

You would certainly benefit from using a responsive framework for your project. It would save you a good amount of headaches. However, seeing the structure of your HTML I would do the following:

Please check the example: http://jsfiddle.net/xLA4q/

HTML:

<div class="nav-content-wrapper">
 <div class="left-nav">asdasdasd ads asd ads asd ad asdasd ad ad a ad</div>
 <div class="content">asd as dad ads ads ads ad ads das ad sad</div>
</div>

CSS:

.nav-content-wrapper{position:relative; overflow:auto; display:block;height:300px;}
.left-nav{float:left;width:30%;height:inherit;}
.content{float:left;width:70%;height:inherit;}

Composition API

Template refs section tells how this has been unified:

• within template, use ref="myEl"; :ref= with a v-for
• within script, have a const myEl = ref(null) and expose it from setup

The reference carries the DOM element from mounting onwards.

I wanted to return all the states to the previous state (without reloading) including the elements added by jquery. The above implementation not gonna works. and I did as follows.

// Set initial HTML description
var defaultHTML;
function DefaultSave() {
  defaultHTML = document.body.innerHTML;
}
// Restore HTML description to initial state
function HTMLRestore() {
  document.body.innerHTML = defaultHTML;
}



DefaultSave()
<input type="button" value="Restore" onclick="HTMLRestore()">

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

Decide a width and check how many characters one line could hold, and then for each key pressed you call a function that looks something like:

function changeHeight()
{
var chars_per_row = 100;
var pixles_per_row = 16;
this.style.height = Math.round((this.value.length / chars_per_row) * pixles_per_row) + 'px';
}

Havn't tested the code.

Override ui-page class in your css:

.ui-page {
    background: url("image.gif");
    background-repeat: repeat;
}

As for the negation, if you want to know if an element hasn't a class you can simply do as Mark said.

if (!currentPage.parent().hasClass('home')) { do what you want }

A POSIX compliant one using the s command:

sed '/CLIENTSCRIPT="foo"/s/.*/&\
CLIENTSCRIPT2="hello"/' file

You can only get the URI arguments with JavaScript.

// get query arguments
var $_GET = {},
    args = location.search.substr(1).split(/&/);
for (var i=0; i<args.length; ++i) {
    var tmp = args[i].split(/=/);
    if (tmp[0] != "") {
        $_GET[decodeURIComponent(tmp[0])] = decodeURIComponent(tmp.slice(1).join("").replace("+", " "));
    }
}

SELECT pid, cid, pname, name1, name2 
FROM customer1 c1, product p 
WHERE p.cid=c1.cid 
UNION SELECT pid, cid, pname, name1, name2 
FROM customer2 c2, product p 
WHERE p.cid=c2.cid;

I extended python's random.shuffle() to take a second arg:

def shuffle_together(x, y):
    assert len(x) == len(y)

    for i in reversed(xrange(1, len(x))):
        # pick an element in x[:i+1] with which to exchange x[i]
        j = int(random.random() * (i+1))
        x[i], x[j] = x[j], x[i]
        y[i], y[j] = y[j], y[i]

That way I can be sure that the shuffling happens in-place, and the function is not all too long or complicated.

Another option

>>> a = ['red', 'blue', 'green', 'red']
>>> b = 'red'
>>> offset = 0;
>>> indices = list()
>>> for i in range(a.count(b)):
...     indices.append(a.index(b,offset))
...     offset = indices[-1]+1
... 
>>> indices
[0, 3]
>>> 

You have to do two things:

• be sure to have imported right appcompat-v7 library in your project structure -> dependencies
• change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

how about this?

fun <- function(x, ...){
  y=NULL
  parms=list(...)
  for (name in names(parms) ) {
    assign(name, parms[[name]])
  }
  print(is.null(y))
}

Then try:

> fun(1,y=4)
[1] FALSE
> fun(1)
[1] TRUE

Cross-browser solution to checking CSS values without DOM manipulation:

function get_style_rule_value(selector, style)
{
 for (var i = 0; i < document.styleSheets.length; i++)
 {
  var mysheet = document.styleSheets[i];
  var myrules = mysheet.cssRules ? mysheet.cssRules : mysheet.rules;

  for (var j = 0; j < myrules.length; j++)
  {
   if (myrules[j].selectorText && myrules[j].selectorText.toLowerCase() === selector)
   {
    return myrules[j].style[style];
   }
  }
 }
};

Usage:

get_style_rule_value('.chart-color', 'backgroundColor')

Sanitized version (forces selector input to lowercase, and allows for use case without leading ".")

function get_style_rule_value(selector, style)
{
 var selector_compare=selector.toLowerCase();
 var selector_compare2= selector_compare.substr(0,1)==='.' ?  selector_compare.substr(1) : '.'+selector_compare;

 for (var i = 0; i < document.styleSheets.length; i++)
 {
  var mysheet = document.styleSheets[i];
  var myrules = mysheet.cssRules ? mysheet.cssRules : mysheet.rules;

  for (var j = 0; j < myrules.length; j++)
  {
    if (myrules[j].selectorText)
    {
     var check = myrules[j].selectorText.toLowerCase();
     switch (check)
     {
      case selector_compare  :
      case selector_compare2 : return myrules[j].style[style];
     }
    }
   }
  }
 }

I saw this post at least twice, because the accepted answer is hard to remeber for me(I rarely use z or j flags and they are seems not platform independant).

The standard never says clearly the exact data length of size_t, so I suggest you should first check the length size_t on your platform then select one of them:

if sizeof(size_t) == 4 use PRIu32
if sizeof(size_t) == 8 use PRIu64

And I suggest using stdint types instead of raw data types for consistancy.

If it's fixed layout you can do like that:

public void onClick(View v) {
   ViewGroup parent = (ViewGroup) IdNumber.this.getParent();
   EditText firstName = (EditText) parent.findViewById(R.id.display_name);
   firstName.setText("Some Text");
}

If you want find the EditText in flexible layout, I will help you later. Hope this help.

Create a new folder, given a parent folder's path:

        string pathToNewFolder = System.IO.Path.Combine(parentFolderPath, "NewSubFolder");
        DirectoryInfo directory = Directory.CreateDirectory(pathToNewFolder); 
       // Will create if does not already exist (otherwise will ignore)

• path to new folder given
• directory information variable so you can continue to manipulate it as you please.

It is because you use a relative path.

The easy way to fix this is by using the __DIR__ magic constant, like:

require_once(__DIR__."/initcontrols/config.php");

From the PHP doc:

The directory of the file. If used inside an include, the directory of the included file is returned

Go to magento/var/report and open the file with the Error log record number name i.e 673618173351 in your case. In that file you can find the complete description of the error.

For log files like system.log and exception.log, go to magento/var/log/.

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.

I'm seeing this in a VS2017 environment. My build script calls VsDevCmd.bat first, and to solve this problem I set the VCTargetsPath environment variable after VsDevCmd and before calling MSBuild:

set VCTargetsPath=%VCIDEInstallDir%VCTargets

In Visual Studio 2017, unchecked the ContextSwitchDeadlock option by:

Fastest way

public static byte[] GetBytes(string text)
{
    return System.Text.ASCIIEncoding.UTF8.GetBytes(text);

EDIT as Makotosan commented this is now the best way:

Encoding.UTF8.GetBytes(text)

You could create triggers to solve this. Here is a tutorial to do so (archived link).

Setting constraints and rules in the database is better than writing special code to handle the same task since it will prevent another developer from writing a different query that bypasses all of the special code and could leave your database with poor data integrity.

For a long time I was copying info to another table using a script since MySQL didn’t support triggers at the time. I have now found this trigger to be more effective at keeping track of everything.

This trigger will copy an old value to a history table if it is changed when someone edits a row. Editor ID and last mod are stored in the original table every time someone edits that row; the time corresponds to when it was changed to its current form.

DROP TRIGGER IF EXISTS history_trigger $$

Another solution would be to keep an Revision field and update this field on save. You could decide that the max is the newest revision, or that 0 is the most recent row. That's up to you.

I have used all of Sam's recommendations above, but I found that the VM command line options are no longer supported as described. (I received an error when used)

As an alternative, I was able to reduce gradle dramatically by adding the following line to the "gradle.properties" file

org.gradle.jvmargs=-Xms512m -Xmx1024m

As of A.S. ver 1.3, the file is located in the same folder level as "gradle.build".

The above configuration is a "memory stack" of 512 meg, and "memory heap" of 1024 meg.

I tested this on a small project, using settings where both memory sizes were set to 256 meg. It limited the JVM sizes as expected. In all my tests, I restarted A.S. to force the JVM to restart.

Hopefully, this will save others dealing with this issue from getting those "Get yourself a better computer" responses. :-)

I'm using gcc as a preprocessor (for html files.) It does just what you want. It expands "#--" directives, then outputs a readable file. (NONE of the other C/HTML preprocessors I've tried do this- they concatenate lines, choke on special characters, etc.) Asuming you have gcc installed, the command line is:

gcc -E -x c -P -C -traditional-cpp code_before.cpp > code_after.cpp

(Doesn't have to be 'cpp'.) There's an excellent description of this usage at http://www.cs.tut.fi/~jkorpela/html/cpre.html.

The "-traditional-cpp" preserves whitespace & tabs.

Here's my interpretation as a Function Instead:

'#######################################################################
'# LoopThroughFiles
'# Function to Loop through files in current directory and return filenames
'# Usage: LoopThroughFiles ActiveWorkbook.Path, "txt" 'inputDirectoryToScanForFile
'# https://stackoverflow.com/questions/10380312/loop-through-files-in-a-folder-using-vba
'#######################################################################
Function LoopThroughFiles(inputDirectoryToScanForFile, filenameCriteria) As String

    Dim StrFile As String
    'Debug.Print "in LoopThroughFiles. inputDirectoryToScanForFile: ", inputDirectoryToScanForFile

    StrFile = Dir(inputDirectoryToScanForFile & "\*" & filenameCriteria)
    Do While Len(StrFile) > 0
        Debug.Print StrFile
        StrFile = Dir

    Loop

End Function

You may also need to make database containing table active

use [dbname]

otherwise you may get error (even if you specify database i.e. dbname.table )

FAILED Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Unable to alter partition. Unable to alter partitions because table or database does not exist.

I used your idea, and found the difference and then just divided by 365 days. Worked a treat.

Then I shifted my cell properties to not display decimals.

Yes; functions (and methods) are first class objects in Python. The following works:

def foo(f):
    print "Running parameter f()."
    f()

def bar():
    print "In bar()."

foo(bar)

Outputs:

Running parameter f().
In bar().

These sorts of questions are trivial to answer using the Python interpreter or, for more features, the IPython shell.

You can use this in event:

google.maps.event.addListener(marker, 'click', function() {  
    // this = marker
    var marker_map = this.getMap();
    this.info.open(marker_map);
    // this.info.open(marker_map, this);
    // Note: If you call open() without passing a marker, the InfoWindow will use the position specified upon construction through the InfoWindowOptions object literal.
});

when you manually open the IP address (via the RUN command or mapping a network drive), your PC will send your credentials over the pipe and the file server will receive authorization from the DC.

When ASP.Net tries, then it is going to try to use the IIS worker user (unless impersonation is turned on which will list a few other issues). Traditionally, the IIS worker user does not have authorization to work across servers (or even in other folders on the web server).

In my case the database was restored and it already had the user used for the connection. I had to drop the user in the database and recreate the user-mapping for the login.

1. Drop the user

   DROP USER [MyUser]
   

It might fail if the user owns any schemas. Those has to assigned to dbo before dropping the user. Get the schemas owned by the user using first query below and then alter the owner of those schemas using second query (HangFire is the schema obtained from previous query).

select * from information_schema.schemata where schema_owner = 'MyUser'
ALTER AUTHORIZATION ON SCHEMA::[HangFire] TO [dbo]     

2. Update user mapping for the user. In management studio go to Security-> Login -> Open the user -> Go to user mapping tab -> Enable the database and grant appropriate role.

Here's what I found during debug.

This won't directly solve your problem as you want to switch on your own user-defined types, but for the benefit of others who only want to switch on built-in types, you can use the TypeCode enumeration:

switch (Type.GetTypeCode(node.GetType()))
{
    case TypeCode.Decimal:
        // Handle Decimal
        break;

    case TypeCode.Int32:
        // Handle Int32
        break;
     ...
}

Find the stable version of the hibernate plugin (Zip or URL for auto update) in the below URL. http://www.jboss.org/tools/download

Do not install everything though. You just need:

1. The entire All JBoss Tools 3.2.0 section
2. Hibernate Tools (HT) from Application Development
3. HT from Data Services
4. JBoss Maven Hibernate Configurator from Maven Support and
5. HT from Web and Java EE Development

That's all!

In 2013, you will be probably using the latest versions of Eclipse and Hibernate. For Eclipse-4.2.2. and JBoss Tools 4.0 you need:

1. From the Abridged JBoss Tools 4.0, the JBoss Hibenate Tools section
2. Hibernate Tools (HT) from Application Development
3. HT from JBoss Data Services
4. JBoss Maven Hibernate Configurator from Maven Support and
5. HT from Web and Java EE Development

Then you are ready to go!

If you are in an ATL/MFC environment, You can use the ATL conversion macro:

#include <atlbase.h>
#include <atlconv.h>

. . .

string myStr("My string");
CA2W unicodeStr(myStr);

You can then use unicodeStr as an LPCWSTR. The memory for the unicode string is created on the stack and released then the destructor for unicodeStr executes.

I made my own way based on Caitlin Morris's answer for fetching all folowers and followings on Instagram. Just copy this code, paste in browser console and wait for a few seconds.

You need to use browser console from instagram.com tab to make it works.

let username = 'USERNAME'
let followers = [], followings = []
try {
  let res = await fetch(`https://www.instagram.com/${username}/?__a=1`)

  res = await res.json()
  let userId = res.graphql.user.id

  let after = null, has_next = true
  while (has_next) {
    await fetch(`https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=` + encodeURIComponent(JSON.stringify({
      id: userId,
      include_reel: true,
      fetch_mutual: true,
      first: 50,
      after: after
    }))).then(res => res.json()).then(res => {
      has_next = res.data.user.edge_followed_by.page_info.has_next_page
      after = res.data.user.edge_followed_by.page_info.end_cursor
      followers = followers.concat(res.data.user.edge_followed_by.edges.map(({node}) => {
        return {
          username: node.username,
          full_name: node.full_name
        }
      }))
    })
  }
  console.log('Followers', followers)

  has_next = true
  after = null
  while (has_next) {
    await fetch(`https://www.instagram.com/graphql/query/?query_hash=d04b0a864b4b54837c0d870b0e77e076&variables=` + encodeURIComponent(JSON.stringify({
      id: userId,
      include_reel: true,
      fetch_mutual: true,
      first: 50,
      after: after
    }))).then(res => res.json()).then(res => {
      has_next = res.data.user.edge_follow.page_info.has_next_page
      after = res.data.user.edge_follow.page_info.end_cursor
      followings = followings.concat(res.data.user.edge_follow.edges.map(({node}) => {

    })
  }
  console.log('Followings', followings)

I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.

Here's an example call, using Quandl-api download in csv

example:

https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31

They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).

There is no linguistic support to do what you're asking for.

You can reflectively access the members of a type at run-time using reflection (e.g. with Class.getDeclaredFields() to get an array of Field), but depending on what you're trying to do, this may not be the best solution.

Example

Here's a simple example to show only some of what reflection is capable of doing.

import java.lang.reflect.*;

public class DumpFields {
    public static void main(String[] args) {
        inspect(String.class);
    }
    static <T> void inspect(Class<T> klazz) {
        Field[] fields = klazz.getDeclaredFields();
        System.out.printf("%d fields:%n", fields.length);
        for (Field field : fields) {
            System.out.printf("%s %s %s%n",
                Modifier.toString(field.getModifiers()),
                field.getType().getSimpleName(),
                field.getName()
            );
        }
    }
}

The above snippet uses reflection to inspect all the declared fields of class String; it produces the following output:

7 fields:
private final char[] value
private final int offset
private final int count
private int hash
private static final long serialVersionUID
private static final ObjectStreamField[] serialPersistentFields
public static final Comparator CASE_INSENSITIVE_ORDER

Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection

These are excerpts from the book:

Given a Class object, you can obtain Constructor, Method, and Field instances representing the constructors, methods and fields of the class. [They] let you manipulate their underlying counterparts reflectively. This power, however, comes at a price:

• You lose all the benefits of compile-time checking.
• The code required to perform reflective access is clumsy and verbose.
• Performance suffers.

As a rule, objects should not be accessed reflectively in normal applications at runtime.

There are a few sophisticated applications that require reflection. Examples include [...omitted on purpose...] If you have any doubts as to whether your application falls into one of these categories, it probably doesn't.

Is this not good enough:

<input type="password" ng-model="passwd1" />
<input type="password" ng-model="passwd2" />
<label ng-show="passwd1 != passwd2">Passwords do not match...</label>
<button ng-disabled="passwd1 != passwd2">Save</button>

Simple, and works just fine for me.

An intuitive script: dplyr::select_if(~!all(is.na(.))). It literally keeps only not-all-elements-missing columns. (to delete all-element-missing columns).

> df <- data.frame( id = 1:10 , nas = rep( NA , 10 ) , vals = sample( c( 1:3 , NA ) , 10 , repl = TRUE ) )

> df %>% glimpse()
Observations: 10
Variables: 3
$ id   <int> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
$ nas  <lgl> NA, NA, NA, NA, NA, NA, NA, NA, NA, NA
$ vals <int> NA, 1, 1, NA, 1, 1, 1, 2, 3, NA

> df %>% select_if(~!all(is.na(.))) 
   id vals
1   1   NA
2   2    1
3   3    1
4   4   NA
5   5    1
6   6    1
7   7    1
8   8    2
9   9    3
10 10   NA

For anyone else finding this - its worth noting that you can set the key value in the input name. Thanks to the answer in POSTing Form Fields with same Name Attribute you also can interplay strings or integers without quoting.

The answers assume that you don't mind the key value coming back for PHP however you can set name=[yourval] (string or int) which then allows you to refer to an existing record.

if you want to delete the whole table, you must follow the next SQL instruction

Delete  FROM TABLE Where PRIMARY_KEY_ is Not NULL;

There were a few ways I found to do this:

• Firefox: Add Exception -> Get Certificat -> View -> Details -> Export...
• KeyMan (http://www.alphaworks.ibm.com/tech/keyman) You can get SSL cert directly from the File -> Import menu
• InstallCert (Code by Andreas Sterbenz)

    java InstallCert [host]:[port] 
    keytool -exportcert -keystore jssecacerts -storepass changeit -file output.cert
    keytool -importcert -keystore [DESTINATION_KEYSTORE] -file output.cert

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

It's Varargs :)

The varargs short for variable-length arguments is a feature that allows the method to accept variable number of arguments (zero or more). With varargs it has become simple to create methods that need to take a variable number of arguments. The feature of variable argument has been added in Java 5.

Syntax of varargs

A vararg is secified by three ellipsis (three dots) after the data type, its general form is

return_type method_name(data_type ... variableName){
}  

Need for varargs

Prior to Java 5, in case there was a need of variable number of arguments, there were two ways to handle it

If the max number of arguments, a method can take was small and known, then overloaded versions of the method could be created. If the maximum number of arguments a method could take was large or/and unknown then the approach was to put those arguments in an array and pass them to a method which takes array as a parameter. These 2 approaches were error-prone - constructing an array of parameters every time and difficult to maintain - as the addition of new argument may result in writing a new overloaded method.

Advantages of varargs

Offers a much simpler option. Less code as no need to write overloaded methods.

Example of varargs

public class VarargsExample {
 public void displayData(String ... values){
  System.out.println("Number of arguments passed " + values.length);
  for(String s : values){
   System.out.println(s + " ");
  }
 }

 public static void main(String[] args) {
  VarargsExample vObj = new VarargsExample();
  // four args
  vObj.displayData("var", "args", "are", "passed");
  //three args
  vObj.displayData("Three", "args", "passed");
  // no-arg
  vObj.displayData();
 }
}
Output

Number of arguments passed 4
var 
args 
are 
passed 
Number of arguments passed 3
Three 
args 
passed 
Number of arguments passed 0

It can be seen from the program that length is used here to find the number of arguments passed to the method. It is possible because varargs are implicitly passed as an array. Whatever arguments are passed as varargs are stored in an array which is referred by the name given to varargs. In this program array name is values. Also note that method is called with different number of argument, first call with four arguments, then three arguments and then with zero arguments. All these calls are handled by the same method which takes varargs.

Restriction with varargs

It is possible to have other parameters with varargs parameter in a method, however in that case, varargs parameter must be the last parameter declared by the method.

void displayValues(int a, int b, int … values) // OK
   void displayValues(int a, int b, int … values, int c) // compiler error

Another restriction with varargs is that there must be only one varargs parameter.

void displayValues(int a, int b, int … values, int … moreValues) // Compiler error

Overloading varargs Methods

It is possible to overload a method that takes varargs parameter. Varargs method can be overloaded by -

Types of its vararg parameter can be different. By adding other parameters. Example of overloading varargs method

public class OverloadingVarargsExp {
 // Method which has string vararg parameter
 public void displayData(String ... values){
  System.out.println("Number of arguments passed " + values.length);
  for(String s : values){
   System.out.println(s + " ");
  }
 }

 // Method which has int vararg parameter
 public void displayData(int ... values){
  System.out.println("Number of arguments passed " + values.length);
  for(int i : values){
   System.out.println(i + " ");
  }
 }

 // Method with int vararg and one more string parameter
 public void displayData(String a, int ... values){
  System.out.println(" a " + a);
  System.out.println("Number of arguments passed " + values.length);
  for(int i : values){
   System.out.println(i + " ");
  }
 }

 public static void main(String[] args) {
  OverloadingVarargsExp vObj = new OverloadingVarargsExp();
  // four string args
  vObj.displayData("var", "args", "are", "passed");

  // two int args
  vObj.displayData(10, 20);

  // One String param and two int args
  vObj.displayData("Test", 20, 30);
 }
}
Output

Number of arguments passed 4
var 
args 
are 
passed 

Number of arguments passed 2
10 
20

 a Test
Number of arguments passed 2
20 
30 

Varargs and overloading ambiguity

In some cases call may be ambiguous while we have overloaded varargs method. Let's see an example

public class OverloadingVarargsExp {
 // Method which has string vararg parameter
 public void displayData(String ... values){
  System.out.println("Number of arguments passed " + values.length);
  for(String s : values){
   System.out.println(s + " ");
  }
 }

 // Method which has int vararg parameter
 public void displayData(int ... values){
  System.out.println("Number of arguments passed " + values.length);
  for(int i : values){
   System.out.println(i + " ");
  }
 }

 public static void main(String[] args) {
  OverloadingVarargsExp vObj = new OverloadingVarargsExp();
  // four string args
  vObj.displayData("var", "args", "are", "passed");

  // two int args
  vObj.displayData(10, 20);

  // This call is ambiguous
  vObj.displayData();
 }
}

In this program when we make a call to displayData() method without any parameter it throws error, because compiler is not sure whether this method call is for displayData(String ... values) or displayData(int ... values)

Same way if we have overloaded methods where one has the vararg method of one type and another method has one parameter and vararg parameter of the same type, then also we have the ambiguity - As Exp - displayData(int ... values) and displayData(int a, int ... values)

These two overloaded methods will always have ambiguity.

Use

"$filepath"_newstap.sh

or

${filepath}_newstap.sh

or

$filepath\_newstap.sh

_ is a valid character in identifiers. Dot is not, so the shell tried to interpolate $filepath_newstap.

You can use set -u to make the shell exit with an error when you reference an undefined variable.

It can be due to a number of reasons happening when configuring the listener. Best way is to log and see the actual error. You can do this by adding a logging.properties file to the root of your classpath with the following contents:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

To print those numbers in C do the following:

printf("%d", addNumbers(a,b));

I don't know about JSON.NET, but it works fine with JavaScriptSerializer from System.Web.Extensions.dll (.NET 3.5 SP1):

    public PositionType positionType { get; set; }
    public Ref reference { get; set; }
    public List<SubObject> objects { get; set; }
}
static class Program
{

    const string json = @"{
  ""displayFieldName"" : ""OBJECT_NAME"",

    static void Main()
    {
        JavaScriptSerializer ser = new JavaScriptSerializer();
        Foo foo = ser.Deserialize<Foo>(json);
    }


}

Edit:

Json.NET works using the same JSON and classes.

Foo foo = JsonConvert.DeserializeObject<Foo>(json);

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C
double              D
float               F
int                 I
long                J
short               S 
class or interface  Lclassname;

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

Use the "MMMM" format specifier:

string month = dateTime.ToString("MMMM");

You can use String.Format, see the code [via How-to Geek]:

decimal moneyvalue = 1921.39m;
string html = String.Format("Order Total: {0:C}", moneyvalue);
Console.WriteLine(html);
// Output: $1,921.39

Use System.Windows.Forms.Timer.

private Timer timer1; 
public void InitTimer()
{
    timer1 = new Timer();
    timer1.Tick += new EventHandler(timer1_Tick);
    timer1.Interval = 2000; // in miliseconds
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    isonline();
}

You can call InitTimer() in Form1_Load().

The actual answer is "use mutation observers" (as outlined in this question: Determining if a HTML element has been added to the DOM dynamically), however support (specifically on IE) is limited (http://caniuse.com/mutationobserver).

So the actual ACTUAL answer is "Use mutation observers.... eventually. But go with Jose Faeti's answer for now" :)

Use the boolean() XPath function

The boolean function converts its argument to a boolean as follows:

• a number is true if and only if it is neither positive or negative zero nor NaN

• a node-set is true if and only if it is non-empty

• a string is true if and only if its length is non-zero

• an object of a type other than the four basic types is converted to a boolean in a way that is dependent on that type

If there is an AttachedXml in the CreditReport of primary Consumer, then it will return true().

boolean(/mc:Consumers
          /mc:Consumer[@subjectIdentifier='Primary']
            //mc:CreditReport/mc:AttachedXml)

You want to replace it, not strip it:

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

In python 3.6.3 with pandas 0.22.0 you can also use concat as long as you set as index the columns you want to use for the joining

pd.concat(
    (iDF.set_index('name') for iDF in [df1, df2, df3]),
    axis=1, join='inner'
).reset_index()

where df1, df2, and df3 are defined as in John Galt's answer

import pandas as pd
df1 = pd.DataFrame(np.array([
    ['a', 5, 9],
    ['b', 4, 61],
    ['c', 24, 9]]),
    columns=['name', 'attr11', 'attr12']
)
df2 = pd.DataFrame(np.array([
    ['a', 5, 19],
    ['b', 14, 16],
    ['c', 4, 9]]),
    columns=['name', 'attr21', 'attr22']
)
df3 = pd.DataFrame(np.array([
    ['a', 15, 49],
    ['b', 4, 36],
    ['c', 14, 9]]),
    columns=['name', 'attr31', 'attr32']
)

NSDate *currentDate = [NSDate date];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setHour:10];

A simpler solution on recent versions of tmux (tested on 1.9) you can now do :

tmux detach -a

-a is for all other client on this session except the current one

You can alias it in your .[bash|zsh]rc

alias takeover="tmux detach -a"

Workflow: You can connect to your session normally, and if you are bothered by another session that forced down your tmux window size you can simply call takeover.

As your data already in varchar, you have to convert it into date first:

select convert(varchar(10), cast(ts as date), 101) from <your table>

In case anyone is running in a Spring Boot app, and you want to read the response body of a RestTemplate (which is why I want to read a stream twice), there is a clean(er) way of doing this.

First of all, you need to use Spring's StreamUtils to copy the stream to a String:

String text = StreamUtils.copyToString(response.getBody(), Charset.defaultCharset()))

But that's not all. You also need to use a request factory that can buffer the stream for you, like so:

ClientHttpRequestFactory factory = new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory());
RestTemplate restTemplate = new RestTemplate(factory);

Or, if you're using the factory bean, then (this is Kotlin but nevertheless):

@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
fun createRestTemplate(): RestTemplate = RestTemplateBuilder()
  .requestFactory { BufferingClientHttpRequestFactory(SimpleClientHttpRequestFactory()) }
  .additionalInterceptors(loggingInterceptor)
  .build()

Source: https://objectpartners.com/2018/03/01/log-your-resttemplate-request-and-response-without-destroying-the-body/

public void listFilesForFolder(final File folder) {
    for (final File fileEntry : folder.listFiles()) {
        if (fileEntry.isDirectory()) {
            listFilesForFolder(fileEntry);
        } else {
            System.out.println(fileEntry.getName());
        }
    }
}

final File folder = new File("/home/you/Desktop");
listFilesForFolder(folder);

Files.walk API is available from Java 8.

try (Stream<Path> paths = Files.walk(Paths.get("/home/you/Desktop"))) {
    paths
        .filter(Files::isRegularFile)
        .forEach(System.out::println);
} 

The example uses try-with-resources pattern recommended in API guide. It ensures that no matter circumstances the stream will be closed.

You can use this extension known as Project Manager

In this the projects are saved in a file projects.json, just save the project and by pressing Shift + Alt + P you can see the list of all your saved projects, from there you can easily switch your projects.

Extend HttpServletRequestWrapper, override the header getters to return the parameters as well:

public class AddParamsToHeader extends HttpServletRequestWrapper {
    public AddParamsToHeader(HttpServletRequest request) {
        super(request);
    }

    public String getHeader(String name) {
        String header = super.getHeader(name);
        return (header != null) ? header : super.getParameter(name); // Note: you can't use getParameterValues() here.
    }

    public Enumeration getHeaderNames() {
        List<String> names = Collections.list(super.getHeaderNames());
        names.addAll(Collections.list(super.getParameterNames()));
        return Collections.enumeration(names);
    }
}

..and wrap the original request with it:

chain.doFilter(new AddParamsToHeader((HttpServletRequest) request), response);

That said, I personally find this a bad idea. Rather give it direct access to the parameters or pass the parameters to it.

You can simply use this one line code to resize your image in visual basic .net

Public Shared Function ResizeImage(ByVal InputImage As Image) As Image
        Return New Bitmap(InputImage, New Size(64, 64))

Where;

1. "InputImage" is the image you want to resize.
2. "64 X 64" is the required size you may change it as your needs i.e 32X32 etc.

Open a command prompt as admin and run this command:

bcdedit /set {current} hypervisorlaunchtype off

After a reboot, Hyper-V is still installed but the Hypervisor is no longer running. Now you can use VMware without any issues.

If you need Hyper-V again, open a command prompt as admin and run this command:

bcdedit /set {current} hypervisorlaunchtype auto

I had a similar issue for setting proxy server on a container.

The solution I'm using is an entrypoint script, and another script for environment variables configuration. Using RUN, you assure the configuration script runs on build, and ENTRYPOINT when you run the container.

--build-arg is used on command line to set proxy user and password.

As I need the same environment variables on container startup, I used a file to "persist" it from build to run.

The entrypoint script looks like:

#!/bin/bash
# Load the script of environment variables
. /root/configproxy.sh
# Run the main container command
exec "$@"

configproxy.sh

#!/bin/bash

function start_config {
read u p < /root/proxy_credentials

export HTTP_PROXY=http://$u:[email protected]:8080
export HTTPS_PROXY=https://$u:[email protected]:8080

/bin/cat <<EOF > /etc/apt/apt.conf 
Acquire::http::proxy "http://$u:[email protected]:8080";
Acquire::https::proxy "https://$u:[email protected]:8080";
EOF
}

if [ -s "/root/proxy_credentials" ]
then
start_config
fi

And in the Dockerfile, configure:

# Base Image
FROM ubuntu:18.04

ARG user
ARG pass

USER root

# -z the length of STRING is zero
# [] are an alias for test command
# if $user is not empty, write credentials file
RUN if [ ! -z "$user" ]; then echo "${user} ${pass}">/root/proxy_credentials ; fi

#copy bash scripts
COPY configproxy.sh /root
COPY startup.sh .

RUN ["/bin/bash", "-c", ". /root/configproxy.sh"]

# Install dependencies and tools
#RUN apt-get update -y && \
#    apt-get install -yqq --no-install-recommends \
#    vim iputils-ping

ENTRYPOINT ["./startup.sh"]
CMD ["sh", "-c", "bash"]

Build without proxy settings

docker build -t img01 -f Dockerfile . 

Build with proxy settings

docker build -t img01 --build-arg user=<USER> --build-arg pass=<PASS> -f Dockerfile . 

Take a look here.

Because you defined the struct as consisting of char arrays, the two strings are the structure and freeing the struct is sufficient, nor is there a way to free the struct but keep the arrays. For that case you would want to do something like struct { char *firstName, *lastName; }, but then you need to allocate memory for the names separately and handle the question of when to free that memory.

Aside: Is there a reason you want to keep the names after the struct has been freed?

I had a similar kind of scenario, but in my case string is not a 1st level attribute. It is inside an object. In here I couldn't find a suitable answer for it. So I thought to share my solution with you all(Hope this will help anyone with a similar kind of problem).

Parent Collection 

{
"Child":
{
"name":"Random Name",
"Age:"09"
}
}

Ex: If we need to get only collections that having child's name's length is higher than 10 characters.

 db.getCollection('Parent').find({$where: function() { 
for (var field in this.Child.name) { 
    if (this.Child.name.length > 10) 
        return true;

}
}})

Sometimes You just open too much applications in Windows and make the gradle have no enough memory to start the daemon process.So when you come across with this situation,you can just close some applications such as Chrome and so on. Then restart your android studio.

I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.

The example is available here http://plnkr.co/edit/EsW7mV?p=preview

Here goes the code:

app.controller('MainCtrl', function($scope) {

  $scope.updateTodo = function(indx) {
    console.log(indx);
  };

  $scope.cancelEdit = function(value) {
    console.log('Canceled editing', value);
  };

  $scope.todos = [
    {id:123, title: 'Lord of the things'},
    {id:321, title: 'Hoovering heights'},
    {id:231, title: 'Watership brown'}
  ];
});

// On esc event
app.directive('onEsc', function() {
  return function(scope, elm, attr) {
    elm.bind('keydown', function(e) {
      if (e.keyCode === 27) {
        scope.$apply(attr.onEsc);
      }
    });
  };
});

// On enter event
app.directive('onEnter', function() {
  return function(scope, elm, attr) {
    elm.bind('keypress', function(e) {
      if (e.keyCode === 13) {
        scope.$apply(attr.onEnter);
      }
    });
  };
});

// Inline edit directive
app.directive('inlineEdit', function($timeout) {
  return {
    scope: {
      model: '=inlineEdit',
      handleSave: '&onSave',
      handleCancel: '&onCancel'
    },
    link: function(scope, elm, attr) {
      var previousValue;

      scope.edit = function() {
        scope.editMode = true;
        previousValue = scope.model;

        $timeout(function() {
          elm.find('input')[0].focus();
        }, 0, false);
      };
      scope.save = function() {
        scope.editMode = false;
        scope.handleSave({value: scope.model});
      };
      scope.cancel = function() {
        scope.editMode = false;
        scope.model = previousValue;
        scope.handleCancel({value: scope.model});
      };
    },
    templateUrl: 'inline-edit.html'
  };
});

Directive template:

<div>
  <input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
  <button ng-click="cancel()" ng-show="editMode">cancel</button>
  <button ng-click="save()" ng-show="editMode">save</button>
  <span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
    <span ng-hide="editMode" ng-click="edit()">{{model}}</span>
    <a ng-show="showEdit" ng-click="edit()">edit</a>
  </span>
</div>

To use it just add water:

<div ng-repeat="todo in todos" 
     inline-edit="todo.title" 
     on-save="updateTodo($index)" 
     on-cancel="cancelEdit(todo.title)"></div>

UPDATE:

Another option is to use the readymade Xeditable for AngularJS:

http://vitalets.github.io/angular-xeditable/

$percentage = 50;
$totalWidth = 350;

$new_width = ($percentage / 100) * $totalWidth;

Mesos and Kubernetes can both be used to manage a cluster of machines and abstract away the hardware.

Mesos, by design, doesn't provide you with a scheduler (to decide where and when to run processes and what to do if the process fails), you can use something like Marathon or Chronos, or write your own.

Kubernetes will do scheduling for you out of the box, and can be used as a scheduler for Mesos (please correct me if I'm wrong here!) which is where you can use them together. Mesos can have multiple schedulers sharing the same cluster, so in theory you could run kubernetes and chronos together on the same hardware.

Super simplistically: if you want control over how your containers are scheduled, go for Mesos, otherwise Kubernetes rocks.

If you closed the project, you can open it again easily by going to the top bar (alt) > ?Project > Open Project Top menu > Project > Open Project You will get a menu where you can open closed projects that can be preventing you from opening these projects through the File menu. The window that lets you open any closed projects after you go through the menu listed previously

Command mvnw uses Maven that is by default downloaded to ~/.m2/wrapper on the first use.

URL with Maven is specified in each project at .mvn/wrapper/maven-wrapper.properties:

distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.3.9/apache-maven-3.3.9-bin.zip

To update or change Maven version invoke the following (remember about --non-recursive for multi-module projects):

./mvnw io.takari:maven:wrapper -Dmaven=3.3.9 

or just modify .mvn/wrapper/maven-wrapper.properties manually.

To generate wrapper from scratch using Maven (you need to have it already in PATH run:

mvn io.takari:maven:wrapper -Dmaven=3.3.9 

In today's date this solution works for me:

/**
 * A generic confirmation for risky actions.
 * Usage: Add attributes: ng-really-message="Are you sure"? ng-really-click="takeAction()" function
 */
angular.module('app').directive('ngReallyClick', [function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            element.bind('click', function() {
                var message = attrs.ngReallyMessage;
                if (message && confirm(message)) {
                    scope.$apply(attrs.ngReallyClick);
                }
            });
        }
    }
}]);

Had this problem on windows 10, eclipse Neon Release (4.6.0) and MSYS2 installed. Eclipse kept complaining that "Program 'g++' not found in PATH” and "Program 'gcc' not found in PATH”, yet it was compiling and running my C++ code. From the command prompt, I could run g++.

Solution was to define the C++ Environmental variable for eclipse called 'PATH' to point to windows variable called 'path' also $(Path). Menus: Preferences>>C/C++>>Build>>Environment

Looks like eclipse is case sensitive with the name of this environmental, while windows doesn't care about the case.

visibility:hidden preserves the space; display:none doesn't.

2.39KB minified. One file. https://github.com/rhroyston/clock-js

Current Time is

var str = clock.month;
var m = str.charAt(0).toUpperCase() + str.slice(1,3); //gets you abbreviated month
clock.weekday + ' ' + clock.time + ' ' + clock.day + ' ' + m + ' ' + clock.year; //"tuesday 5:50 PM 3 May 2016"

Piecing things together from here and other places, this is what I came up with that works on unbuntu 12.04 and centOS6

Create an file in /etc/rsyslog.d/ that ends in .conf and add the following text

local6.*        /var/log/my-logfile

Restart rsyslog, reloading did NOT seem to work for the new log files. Maybe it only reloads existing conf files?

sudo restart rsyslog

Then you can use this test program to make sure it actually works.

• A ref variable needs to be initialized before passing it in.
• An out variable needs to be set in your function implementation
• out parameters can be thought of as additional return variables (not input)
• ref parameters can be thought of as both input and output variables.

I think this is a better approach. Simple and straight forward.

public function sizeFilter( $bytes )
{
    $label = array( 'B', 'KB', 'MB', 'GB', 'TB', 'PB' );
    for( $i = 0; $bytes >= 1024 && $i < ( count( $label ) -1 ); $bytes /= 1024, $i++ );
    return( round( $bytes, 2 ) . " " . $label[$i] );
}

In response to jt. You are correct, the HTML with just the password is susceptible to the Man in the middle attack. However, you can seed it with a GUID from the server ...

$.post(
  'includes/login.php', 
  { user: username, pass: $.md5(password + GUID) },
   onLogin, 
  'json' );

This would defeat the Man-In-The middle ... in that the server would generate a new GUID for each attempt.

Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:

1. Ctrl-G
2. A1:X50 Enter
3. Delete

Unless you have to do this very often, entering and then triggering the VBAcode is more effort.

And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S to select Goto Special and here select Formulas or Values.

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

Using the TreeMap you can sort the map.

Map<String, String> map = new HashMap<>();        
Map<String, String> treeMap = new TreeMap<>(map);

In fact when you open the pom.xml, you should see 5 tabs in the bottom. Click the pom.xml, and you can type whatever dependencies you want.

In java-8, they introduced the method removeIf which takes a Predicate as parameter.

So it will be easy as:

List<String> list = new ArrayList<>(Arrays.asList("How are you",
                                                  "How you doing",
                                                  "Joe",
                                                  "Mike"));
list.removeIf(s -> !s.contains("How"));

The IN clause describes a set of values, and sets do not have order.

Your solution with a join and then ordering on the display_order column is the most nearly correct solution; anything else is probably a DBMS-specific hack (or is doing some stuff with the OLAP functions in standard SQL). Certainly, the join is the most nearly portable solution (though generating the data with the display_order values may be problematic). Note that you may need to select the ordering columns; that used to be a requirement in standard SQL, though I believe it was relaxed as a rule a while ago (maybe as long ago as SQL-92).

First off, your quoted code is not JSON. Your code is JavaScript object literal notation. JSON is a subset of that designed for easier parsing.

Your code defines an object (data) containing an array (items) of objects (each with an id, name, and type).

You don't need or want jQuery for this, just JavaScript.

Adding an item:

data.items.push(
    {id: "7", name: "Douglas Adams", type: "comedy"}
);

That adds to the end. See below for adding in the middle.

Removing an item:

There are several ways. The splice method is the most versatile:

data.items.splice(1, 3); // Removes three items starting with the 2nd,
                         // ("Witches of Eastwick", "X-Men", "Ordinary People")

splice modifies the original array, and returns an array of the items you removed.

Adding in the middle:

splice actually does both adding and removing. The signature of the splice method is:

removed_items = arrayObject.splice(index, num_to_remove[, add1[, add2[, ...]]]);

• index - the index at which to start making changes
• num_to_remove - starting with that index, remove this many entries
• addN - ...and then insert these elements

So I can add an item in the 3rd position like this:

data.items.splice(2, 0,
    {id: "7", name: "Douglas Adams", type: "comedy"}
);

What that says is: Starting at index 2, remove zero items, and then insert this following item. The result looks like this:

var data = {items: [
    {id: "1", name: "Snatch", type: "crime"},
    {id: "2", name: "Witches of Eastwick", type: "comedy"},
    {id: "7", name: "Douglas Adams", type: "comedy"},     // <== The new item
    {id: "3", name: "X-Men", type: "action"},
    {id: "4", name: "Ordinary People", type: "drama"},
    {id: "5", name: "Billy Elliot", type: "drama"},
    {id: "6", name: "Toy Story", type: "children"}
]};

You can remove some and add some at once:

data.items.splice(1, 3,
    {id: "7", name: "Douglas Adams", type: "comedy"},
    {id: "8", name: "Dick Francis", type: "mystery"}
);

...which means: Starting at index 1, remove three entries, then add these two entries. Which results in:

var data = {items: [
    {id: "1", name: "Snatch", type: "crime"},
    {id: "7", name: "Douglas Adams", type: "comedy"},
    {id: "8", name: "Dick Francis", type: "mystery"},
    {id: "4", name: "Ordinary People", type: "drama"},
    {id: "5", name: "Billy Elliot", type: "drama"},
    {id: "6", name: "Toy Story", type: "children"}
]};

Here is an other example:

<button type="submit" name="submit" style="border: none; background-color: white">

You need to commit or destroy any unsaved changes before you switch branch.

Git won't let you switch branch if it means unsaved changes would be removed.

It is not possible to export an Android library as a jar file. It is possible, however, to export it as aar file. Aar files being the new binary format for Android libraries. There's info about them in Google I/O, the New Build System video.

First, build the library in Android Studio or from command line issuing gradle build from your library's root directory.

This will result in <yourlibroot>/libs/build/yourlib.aar file.

This aar file is a binary representation of your library and can be added to your project instead of the library as a dependency project.

To add aar file as a dependency you have to publish it to the maven central or to your local maven repository, and then refer the aar file in your project's gradle.build file.

However, this step is a bit convoluted. I've found a good explanation how to do so here:

http://www.flexlabs.org/2013/06/using-local-aar-android-library-packages-in-gradle-builds

I added the following Javascript to prevent clicks on disabled links:

$(".nav-tabs a[data-toggle=tab]").on("click", function(e) {
  if ($(this).hasClass("disabled")) {
    e.preventDefault();
    return false;
  }
});

It's bitwise XOR, Java does not have an exponentiation operator, you would have to use Math.pow() instead.

The Composer bin directory is set and stored in bin-dir config variable and can be different depending on your setup. Running the command composer global config bin-dir --absolute will tell you the absolute path to your global composer bin directory. Using this command you can modify your .bash_profile to add it to your PATH exactly how it is configured.

# Add Composer bin-dir to PATH if it is installed.
command -v composer >/dev/null 2>&1 && {
        COMPOSER_BIN_DIR=$(composer global config bin-dir --absolute 2> /dev/null)
        PATH="$PATH:$COMPOSER_BIN_DIR";
}
export PATH

Doesn't log4j just use the application root directory if you don't specify a root directory in your FileAppender's path property? So you should just be able to use:

log4j.appender.file.File=logs/MyLog.log

It's been awhile since I've done Java web development, but this seems to be the most intuitive, and also doesn't collide with other unfortunately named logs writing to the ${catalina.home}/logs directory.

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

The same problem error happened to me when I tried to present a child view controller instead of its UINavigationViewController parent

Try with this:

public static boolean userNameValidation(String name){

return name.matches("(?i)(^[a-z])((?![? .,'-]$)[ .]?[a-z]){3,24}$");
}

You also can use graceful restart the apache server with service apache2 reload or apachectl -k graceful. As the apache doc says:

The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately.

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

This is not supported by Angular CLI and they are in no mood to include it any time soon.

Here is the link to the actual created issue - https://github.com/angular/angular-cli/issues/1776

And a screenshot of the solution from the officials -

I too had same problem but after searching solved this. go to menu --> window-->preferences-->maven-->Installations-->add--> in place of installation home add path to the directory in which you installed maven-->finish-->check the box of newly added content-->apply-->ok. now create new maven project but remember try with different group id and artifact id.

I was getting the read-only problem even when I was selecting the primary key. I eventually figured out it was a casing problem. Apparently the PK column must be cased the same as defined in the table. using: workbench 6.3 on windows

Read-Only

SELECT leadid,firstname,lastname,datecreated FROM lead;

Allowed edit

SELECT LeadID,firstname,lastname,datecreated FROM lead;

Example:

Process process = Process.Start(@"Data\myApp.exe");
int id = process.Id;
Process tempProc = Process.GetProcessById(id);
this.Visible = false;
tempProc.WaitForExit();
this.Visible = true;

Tried to implement jfelectron's solution because it is a "rock-solid solution to these issues that conforms with the 'Android Way' of things" but it took some time to look up and put together all the elements mentioned. Ended up with this slightly different, and I think more elegant, solution posted here in it's entirety.

Uses an IntentService fired from an activity to perform the long running task on a separate thread. The service fires back sticky Broadcast Intents to the activity which update the dialog. The Activity uses showDialog(), onCreateDialog() and onPrepareDialog() to eliminate the need to have persistent data passed in the application object or the savedInstanceState bundle. This should work no matter how your application is interrupted.

Activity Class:

public class TesterActivity extends Activity {
private ProgressDialog mProgressDialog;
private static final int PROGRESS_DIALOG = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button b = (Button) this.findViewById(R.id.test_button);
    b.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            buttonClick();
        }
    });
}

private void buttonClick(){
    clearPriorBroadcast();
    showDialog(PROGRESS_DIALOG);
    Intent svc = new Intent(this, MyService.class);
    startService(svc);
}

protected Dialog onCreateDialog(int id) {
    switch(id) {
    case PROGRESS_DIALOG:
        mProgressDialog = new ProgressDialog(TesterActivity.this);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setMax(MyService.MAX_COUNTER);
        mProgressDialog.setMessage("Processing...");
        return mProgressDialog;
    default:
        return null;
    }
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    switch(id) {
    case PROGRESS_DIALOG:
        // setup a broadcast receiver to receive update events from the long running process
        IntentFilter filter = new IntentFilter();
        filter.addAction(MyService.BG_PROCESS_INTENT);
        registerReceiver(new MyBroadcastReceiver(), filter);
        break;
    }
}

public class MyBroadcastReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.hasExtra(MyService.KEY_COUNTER)){
            int count = intent.getIntExtra(MyService.KEY_COUNTER, 0);
            mProgressDialog.setProgress(count);
            if (count >= MyService.MAX_COUNTER){
                dismissDialog(PROGRESS_DIALOG);
            }
        }
    }
}

/*
 * Sticky broadcasts persist and any prior broadcast will trigger in the 
 * broadcast receiver as soon as it is registered.
 * To clear any prior broadcast this code sends a blank broadcast to clear

 * setup in onPrepareDialog()
 */
private void clearPriorBroadcast(){
    Intent broadcastIntent = new Intent();
    broadcastIntent.setAction(MyService.BG_PROCESS_INTENT);
    sendStickyBroadcast(broadcastIntent);
}}

IntentService Class:

public class MyService extends IntentService {

public static final String BG_PROCESS_INTENT = "com.mindspiker.Tester.MyService.TEST";
public static final String KEY_COUNTER = "counter";
public static final int MAX_COUNTER = 100;

public MyService() {
  super("");
}

@Override
protected void onHandleIntent(Intent intent) {
    for (int i = 0; i <= MAX_COUNTER; i++) {
        Log.e("Service Example", " " + i);
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction(BG_PROCESS_INTENT);
        broadcastIntent.putExtra(KEY_COUNTER, i);
        sendStickyBroadcast(broadcastIntent);
    }
}}

Manifest file entries:

I have also used the SimpleViewPagerIndicator from @JROD. It also crashes as described by @manuelJ.

According to his documentation:

SimpleViewPagerIndicator pageIndicator = (SimpleViewPagerIndicator) findViewById(R.id.page_indicator);
pageIndicator.setViewPager(pager);

Make sure you add this line as well:

pageIndicator.notifyDataSetChanged();

It crashes with an array out of bounds exception because the SimpleViewPagerIndicator is not getting instantiated properly and the items are empty. Calling the notifyDataSetChanged results in all the values being set properly or rather reset properly.

You should then get a welcome response from github and will be fine to then push.

What may be happening is that your console is closing before you get a chance to see the output. I would add Console.ReadLine(); after your Console.WriteLine("Hello World"); so your code would look something like this:

static void Main(string[] args)
    {
        Console.WriteLine("Hello World");
        Console.ReadLine();

    }

This way, the console will display "Hello World" and a blinking cursor underneath. The Console.ReadLine(); is the key here, the program waits for the users input before closing the console window.

This is what I have used in the past.

The problem is simple that the PHP-Mail function is not using a well configured SMTP Server.

Nowadays Email-Clients and Servers perform massive checks on the emails sending server, like Reverse-DNS-Lookups, Graylisting and whatevs. All this tests will fail with the php mail() function. If you are using a dynamic ip, its even worse.

Use the PHPMailer-Class and configure it to use smtp-auth along with a well configured, dedicated SMTP Server (either a local one, or a remote one) and your problems are gone.

One of the fundamental principles behind the original C language is that memory is composed of a sequence of bytes, and code need only care about what those bytes mean at the exact moment that they are being used. Modern C allows compilers to impose additional restrictions, but C includes--and C++ retains--the ability to decompose a pointer into a sequence of bytes, assemble any sequence of bytes containing the same values into a pointer, and then use that pointer to access the earlier object.

While that ability can be useful--or even indispensable--in some kinds of applications, a language that includes that ability will be very limited in its ability to support any kind of useful and reliable garbage collection. If a compiler doesn't know everything that has been done with the bits that made up a pointer, it will have no way of knowing whether information sufficient to reconstruct the pointer might exist somewhere in the universe. Since it would be possible for that information to be stored in ways that the computer wouldn't be able to access even if it knew about them (e.g. the bytes making up the pointer might have been shown on the screen long enough for someone to write them down on a piece of paper), it may be literally impossible for a computer to know whether a pointer could possibly be used in the future.

An interesting quirk of many garbage-collected frameworks is that an object reference not defined by the bit patterns contained therein, but by the relationship between the bits held in the object reference and other information held elsewhere. In C and C++, if the bit pattern stored in a pointer identifies an object, that bit pattern will identify that object until the object is explicitly destroyed. In a typical GC system, an object may be represented by a bit pattern 0x1234ABCD at one moment in time, but the next GC cycle might replace all references to 0x1234ABCD with references to 0x4321BABE, whereupon the object would be represented by the latter pattern. Even if one were to display the bit pattern associated with an object reference and then later read it back from the keyboard, there would be no expectation that the same bit pattern would be usable to identify the same object (or any object).

Both

SuperClass.__init__(self, x)

or

super(SubClass,self).__init__( x )

will work (I prefer the 2nd one, as it adheres more to the DRY principle).

Common Query To Check Database Size in SQL Server that supports both Azure and On-Premises-

Method 1 – Using ‘sys.database_files’ System View

SELECT
    DB_NAME() AS [database_name],
    CONCAT(CAST(SUM(
        CAST( (size * 8.0/1024) AS DECIMAL(15,2) )

There's always the hardware route. Purchase two USB to serial converters, and connect them via a NULL modem.

Pro tips: 1) Windows may assign new COM ports to the adapters after every device sleep or reboot. 2) The market leaders in chips for USB to serial are Prolific and FTDI. Both companies are battling knockoffs, and may be blocked in future official Windows drivers. The Linux drivers however work fine with the clones.

Use LINQ .Cast<int>() to convert 2D array to IEnumerable<int>.

LINQPad example:

var arr = new int[,] { 
  { 1, 2, 3 }, 
  { 4, 5, 6 } 
};

IEnumerable<int> values = arr.Cast<int>();
Console.WriteLine(values);

In 2019, it will automatically open a new session, new instance of vs-code. By type

then, type

From the documentation get_or_create:

# get_or_create() a person with similar first names.

p, created = Person.objects.get_or_create(
    first_name='John',
    last_name='Lennon',
    defaults={'birthday': date(1940, 10, 9)},
)

# get_or_create() didn't have to create an object.
>>> created
False

Explanation: Fields to be evaluated for similarity, have to be mentioned outside defaults. Rest of the fields have to be included in defaults. In case CREATE event occurs, all the fields are taken into consideration.

It looks like you need to be returning into a tuple, instead of a single variable, do like this:

customer.source,created = Source.objects.get_or_create(name="Website")

I have wasted a lot of time figuring out what is wrong when I iterate through DOMElements with the code in the accepted answer. This is what worked for me, otherwise every second element disappears from the document:

_getGpxString: function(node) {
          clone = node.cloneNode(true);
          var tmp = document.createElement("div");
          tmp.appendChild(clone);
          return tmp.innerHTML;
        },

This can be due to byte alignment and padding so that the structure comes out to an even number of bytes (or words) on your platform. For example in C on Linux, the following 3 structures:

#include "stdio.h"


struct oneInt {
  int x;
};

struct twoInts {
  int x;
  int y;
};

struct someBits {
  int x:2;
  int y:6;
};


int main (int argc, char** argv) {
  printf("oneInt=%zu\n",sizeof(struct oneInt));
  printf("twoInts=%zu\n",sizeof(struct twoInts));
  printf("someBits=%zu\n",sizeof(struct someBits));
  return 0;
}

Have members who's sizes (in bytes) are 4 bytes (32 bits), 8 bytes (2x 32 bits) and 1 byte (2+6 bits) respectively. The above program (on Linux using gcc) prints the sizes as 4, 8, and 4 - where the last structure is padded so that it is a single word (4 x 8 bit bytes on my 32bit platform).

oneInt=4
twoInts=8
someBits=4

I created a function for a Volley Request. You just need to pass the arguments :

public void callvolly(final String username, final String password){
    RequestQueue MyRequestQueue = Volley.newRequestQueue(this);
    String url = "http://your_url.com/abc.php"; // <----enter your post url here
    StringRequest MyStringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            //This code is executed if the server responds, whether or not the response contains data.
            //The String 'response' contains the server's response.
        }
    }, new Response.ErrorListener() { //Create an error listener to handle errors appropriately.
        @Override
        public void onErrorResponse(VolleyError error) {
            //This code is executed if there is an error.
        }
    }) {
        protected Map<String, String> getParams() {
            Map<String, String> MyData = new HashMap<String, String>();
            MyData.put("username", username);             
            MyData.put("password", password);                
            return MyData;
        }
    };


    MyRequestQueue.add(MyStringRequest);
}

Timezones in PHP at http://www.php.net/manual/en/timezones.php

Here http://www.alteridem.net/2007/08/22/the-yield-statement-in-c/ is very good example:

public static IEnumerable<int> Range( int min, int max )
{
   while ( true )
   {
      if ( min >= max )
      {
         yield break;
      }
      yield return min++;
   }
}

and explanation, that if a yield break statement is hit within a method, execution of that method stops with no return. There are some time situations, when you don't want to give any result, then you can use yield break.

I had this same problem in asp.net mvc, I fixed it by putting this method in my base api controller that all my api controllers inherit from:

    /// <summary>
    /// Get the session from HttpContext.Current, if that is null try to get it from the Request properties.
    /// </summary>
    /// <returns></returns>
    protected HttpContextWrapper GetHttpContextWrapper()
    {
      HttpContextWrapper httpContextWrapper = null;
      if (HttpContext.Current != null)
      {
        httpContextWrapper = new HttpContextWrapper(HttpContext.Current);
      }
      else if (Request.Properties.ContainsKey("MS_HttpContext"))
      {
        httpContextWrapper = (HttpContextWrapper)Request.Properties["MS_HttpContext"];
      }
      return httpContextWrapper;
    }

Then in your api call that you want to access the session you just do:

HttpContextWrapper httpContextWrapper = GetHttpContextWrapper();
var someVariableFromSession = httpContextWrapper.Session["SomeSessionValue"];

I also have this in my Global.asax.cs file like other people have posted, not sure if you still need it using the method above, but here it is just in case:

/// <summary>
/// The following method makes Session available.
/// </summary>
protected void Application_PostAuthorizeRequest()
{
  if (HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath.StartsWith("~/api"))
  {
    HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
  }
}

You could also just make a custom filter attribute that you can stick on your api calls that you need session, then you can use session in your api call like you normally would via HttpContext.Current.Session["SomeValue"]:

  /// <summary>
  /// Filter that gets session context from request if HttpContext.Current is null.
  /// </summary>
  public class RequireSessionAttribute : ActionFilterAttribute
  {
    /// <summary>
    /// Runs before action
    /// </summary>
    /// <param name="actionContext"></param>
    public override void OnActionExecuting(HttpActionContext actionContext)
    {
      if (HttpContext.Current == null)
      {
        if (actionContext.Request.Properties.ContainsKey("MS_HttpContext"))
        {
          HttpContext.Current = ((HttpContextWrapper)actionContext.Request.Properties["MS_HttpContext"]).ApplicationInstance.Context;
        }
      }
    }
  }

Hope this helps.

string minusvalue = TextBox1.Text.ToString();

if (Convert.ToDouble(minusvalue) < 0)
{ 
    // set color of text in TextBox1 to red color and bold.
    TextBox1.ForeColor = Color.Red;
}

You can use global like so:

global._ = require('underscore')

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

This is to how I solved to issue of having multiple inheritance with different variables for initialization and having multiple MixIns with the same function call. I had to explicitly add variables to passed **kwargs and add a MixIn interface to be an endpoint for super calls.

Here A is an extendable base class and B and C are MixIn classes both who provide function f. A and B both expect parameter v in their __init__ and C expects w. The function f takes one parameter y. Q inherits from all three classes. MixInF is the mixin interface for B and C.

• IPython NoteBook Of This Code
• Github Repo with code example

class A(object):
    def __init__(self, v, *args, **kwargs):
        print "A:init:v[{0}]".format(v)
        kwargs['v']=v
        super(A, self).__init__(*args, **kwargs)
        self.v = v


class MixInF(object):
    def __init__(self, *args, **kwargs):
        print "IObject:init"
    def f(self, y):
        print "IObject:y[{0}]".format(y)


class B(MixInF):
    def __init__(self, v, *args, **kwargs):
        print "B:init:v[{0}]".format(v)
        kwargs['v']=v
        super(B, self).__init__(*args, **kwargs)
        self.v = v
    def f(self, y):
        print "B:f:v[{0}]:y[{1}]".format(self.v, y)
        super(B, self).f(y)


class C(MixInF):
    def __init__(self, w, *args, **kwargs):
        print "C:init:w[{0}]".format(w)
        kwargs['w']=w
        super(C, self).__init__(*args, **kwargs)
        self.w = w
    def f(self, y):
        print "C:f:w[{0}]:y[{1}]".format(self.w, y)
        super(C, self).f(y)


class Q(C,B,A):
    def __init__(self, v, w):
        super(Q, self).__init__(v=v, w=w)
    def f(self, y):
        print "Q:f:y[{0}]".format(y)

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

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

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

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

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

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

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

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

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

You can use the following in a pipeline:

git branch: 'master',
    credentialsId: '12345-1234-4696-af25-123455',
    url: 'ssh://[email protected]:company/repo.git'

If you're using the ssh url then your credentials must be username + private key. If you're using the https clone url instead of the ssh one, then your credentials should be username + password.

class Test48{
public static void main (String args[]){
Object Obj=new Hello();
//Hello obj=new Hello;
System.out.println(Obj instanceof String);
System.out.println(Obj instanceof Hello);
System.out.println(Obj instanceof Object);
Hello h=null;
System.out.println(h instanceof Hello);
System.out.println(h instanceof Object);
}
}  

You can either use the css property Fixed, or if you need something more fine-tuned then you need to use javascript and track the scrollTop property which defines where the user agent's scrollbar location is (0 being at the top ... and x being at the bottom)

.Fixed
{
    position: fixed;
    top: 20px;
}

or with jQuery:

$('#ParentContainer').scroll(function() { 
    $('#FixedDiv').css('top', $(this).scrollTop());
});

You can use this cool library to make any kind of animated effect on your element: http://daneden.github.io/animate.css/

This worked for me (win10), place before you import keras:

import os
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

In my case I forgot it was packaging conflict jar vs pom. I forgot to write

<packaging>pom</packaging>

In every child pom.xml file

You could use the longer boringer way

<p style="font-size:14px; color:#538b01; font-weight:bold; font-style:italic;">Enter the competition by</p><p style="font-size:14px; color:#ff00; font-weight:bold; font-style:italic;">summer</p> 

you get the point for the rest

You need to add the permissions below to your AndroidMainfest:

<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Use this standalone ApManager class from anywhere as follows:

ApManager.isApOn(YourActivity.this); // check Ap state :boolean
ApManager.configApState(YourActivity.this); // change Ap state :boolean

Hope this will help someone

To be able to use the jobParameters I think you need to define your reader as scope 'step', but I am not sure if you can do it using annotations.

Using xml-config it would go like this:

<bean id="foo-readers" scope="step"
  class="...MyReader">
  <property name="fileName" value="#{jobExecutionContext['fileName']}" />
</bean>

See further at the Spring Batch documentation.

Perhaps it works by using @Scope and defining the step scope in your xml-config:

<bean class="org.springframework.batch.core.scope.StepScope" />

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

This has been possible since the queryset-refactor branch landed pre-1.0. Ticket 4088 exposed the problem. This should work:

Asset.objects.filter(
    desc__contains=filter,
    project__name__contains="Foo").order_by("desc")

The Django Many-to-one documentation has this and other examples of following Foreign Keys using the Model API.

Since some of the answers give here relate to setting up SMTP in general (and not just for @shinod particular issue where it had been working and stopped), I thought it would be helpful if I updated the answer because this is a lot simpler to do now than it used to be :-)

In PHP 4 the PEAR Mail package is typically already installed, and this really simple tutorial shows you the few lines of code that you need to add to your php file http://email.about.com/od/emailprogrammingtips/qt/PHP_Email_SMTP_Authentication.htm

Most hosting companies list the SMTP settings that you'll need. I use JustHost, and they list theirs at https://my.justhost.com/cgi/help/26 (under Outgoing Mail Server)

Set the aspectRatio property of the chart to 0 did the trick for me...

    var ctx = $('#myChart');

    ctx.height(500);

    var myChart = new Chart(ctx, {
        type: 'horizontalBar',
        data: {
            labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
            datasets: [{
                label: '# of Votes',
                data: [12, 19, 3, 5, 2, 3],
                backgroundColor: [
                    'rgba(255, 99, 132, 0.2)',
                    'rgba(54, 162, 235, 0.2)',
                    'rgba(255, 206, 86, 0.2)',
                    'rgba(75, 192, 192, 0.2)',
                    'rgba(153, 102, 255, 0.2)',
                    'rgba(255, 159, 64, 0.2)'
                ],
                borderColor: [
                    'rgba(255,99,132,1)',
                    'rgba(54, 162, 235, 1)',
                    'rgba(255, 206, 86, 1)',
                    'rgba(75, 192, 192, 1)',
                    'rgba(153, 102, 255, 1)',
                    'rgba(255, 159, 64, 1)'

        },
        maintainAspectRatio: false,
        options: {
            scales: {
                yAxes: [{
                    ticks: {
                        beginAtZero:true
                    }
                }]
            }
        }
    });
myChart.aspectRatio = 0;

Use the headers variable in success and error callbacks

From documentation.

$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  })
  .error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

If you are on the same domain, you should be able to retrieve the response headers back. If cross-domain, you will need to add Access-Control-Expose-Headers header on the server.

Access-Control-Expose-Headers: content-type, cache, ...

I have used Dropbox as my Prive or protected svn. Try the link below. http://foyzulkarim.blogspot.com/2012/12/dropbox-as-svn-repository.html

You could have a look at Sheetfu. The following is an example from the README. It gives a super easy syntax to interact with spreadsheets as if it was a database table.

from sheetfu import Table

spreadsheet = SpreadsheetApp('path/to/secret.json').open_by_id('<insert spreadsheet id here>')
data_range = spreadsheet.get_sheet_by_name('people').get_data_range()

table = Table(data_range, backgrounds=True)

for item in table:
    if item.get_field_value('name') == 'foo':
        item.set_field_value('surname', 'bar')              # this set the surname field value
    age = item.get_field_value('age')
    item.set_field_value('age', age + 1)
    item.set_field_background('age', '#ff0000')             # this set the field 'age' to red color

# Every set functions are batched for speed performance.
# To send the batch update of every set requests you made,
# you need to commit the table object as follow.
table.commit()

Disclaimer: I'm the author of this library.

items[node.ind] = items[node.ind]._replace(v=node.v)

(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

One option is to create a script file.

Right click on the database -> Tasks -> Generate Scripts

Then you can select all the stored procedures and generate the script with all the sps. So you can find the reference from there.

Or

-- Search in All Objects
SELECT OBJECT_NAME(OBJECT_ID),
definition
FROM sys.sql_modules
WHERE definition LIKE '%' + 'CreatedDate' + '%'
GO

-- Search in Stored Procedure Only
SELECT DISTINCT OBJECT_NAME(OBJECT_ID),
object_definition(OBJECT_ID)
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%' + 'CreatedDate' + '%'
GO

I had a similar issue when working on Database restore operation on MS SQL Server 2012.

However, for my own scenario, I just needed to see the progress of the DATABASE RESTORE operation in the script window

All I had to do was add the STATS option to the script:

USE master;
GO

ALTER DATABASE mydb SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO
    
RESTORE DATABASE mydb
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_21-08-2020.bak'
    WITH REPLACE,
         STATS = 10,
         RESTART,
    MOVE 'my_db' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\my_db.mdf',
    MOVE 'my_db_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\mydb_log.ldf'
GO
    
ALTER DATABASE mydb SET MULTI_USER;
GO

And then I switched to the Messages tab of the Script window to see the progress of the DATABASE RESTORE operation:

If you want to get more information after the DATABASE RESTORE operation you can use this command suggested by eythort:

SELECT command, percent_complete, start_time FROM sys.dm_exec_requests where command = 'RESTORE DATABASE'

That's all.

I hope this helps

to get the immediate next sibling ,use this

event.source._elementRef.nativeElement.nextElementSibling

IP Version 4 Only ...

Imports System.Net

Module MainLine
    Sub Main()
        Dim hostName As String = Dns.GetHostName
        Console.WriteLine("Host Name: " & hostName & vbNewLine)
        Console.WriteLine("IP Version 4 Address(es):")
        For Each address In Dns.GetHostEntry(hostName).AddressList().
            Where(Function(p) p.AddressFamily = Sockets.AddressFamily.InterNetwork)
            Console.WriteLine(vbTab & address.ToString)
        Next
        Console.ReadKey()
    End Sub
End Module

In Java7+ you can do this in static methods/fields:

MethodHandles.lookup().lookupClass()

RuDrA05's answer is good, When I edit the XML on eclipse it does not work, but when I edit the XML with notepad++ it DOES work.

The same thing is happening if I read a txt file saved with eclipse or notepad++

Maybe is related to the encoding.

I'll try to explain it visually:

You need to do

./configure --with-ssl=openssl --with-libssl-prefix=/usr/local/ssl

Instead of this

./configure --with-ssl=openssl

If your main element has some child elements or text, you could make use of it.

Position your main element relative (or absolute/fixed) and use both :before and :after positioned absolute (in my situation it had to be absolute, don't know about your's).

Now if you want one more pseudo-element, attach an absolute :before to one of the main element's children (if you have only text, put it in a span, now you have an element), which is not relative/absolute/fixed.

This element will start acting like his owner is your main element.

HTML

<div class="circle">
    <span>Some text</span>
</div>

CSS

.circle {
    position: relative; /* or absolute/fixed */
}

.circle:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle:after {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle span {
    /* not relative/absolute/fixed */
}

.circle span:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

You can use System.nanoTime():

long start = System.nanoTime();
// do stuff
long end = System.nanoTime();
long microseconds = (end - start) / 1000;

to get time in nanoseconds but it is a strictly relative measure. It has no absolute meaning. It is only useful for comparing to other nano times to measure how long something took to do.

I got the solution by using comm

comm -23 file1 file2 

will give you the desired output.

The files need to be sorted first anyway.
