In Mysql 5.7+ you can execute

select current_timestamp(6)

for more details

If you need to remove unbreakable spaces too, you can upgrade your code like this :

st.replaceAll("[\\s|\\u00A0]+", "");

PSH> $cred = Get-Credential

PSH> $cred | Export-CliXml c:\temp\cred.clixml

PSH> $cred2 = Import-CliXml c:\temp\cred.clixml

That hashes it against your SID and the machine's SID, so the file is useless on any other machine, or in anyone else's hands.

I think that the handling of a dialog should be the responsibility of the view, and the view needs to have code to support that.

If you change the ViewModel - View interaction to handle dialogs then the ViewModel is dependant on that implementation. The simplest way to deal with this problem is to make the View responsible for performing the task. If that means showing a dialog then fine, but could also be a status message in the status bar etc.

My point is that the whole point of the MVVM pattern is to separate business logic from the GUI, so you shouldn't be mixing GUI logic (to display a dialog) in the business layer (the ViewModel).

You can't have cells of arbitrarily different widths, this is generally a standard behaviour of tables from any space, e.g. Excel, otherwise it's no longer a table but just a list of text.

You can however have cells span multiple columns, such as:

<table>
    <tr>
        <td>25</td>
        <td>50</td>
        <td>25</td>
    </tr>
    <tr>
        <td colspan="2">75</td>
        <td>20</td>
    </tr>
</table>

As an aside, you should avoid using style attributes like border and bgcolor and prefer CSS for those.

This explicitly prints 0 if installed else 1 using only awk:

dpkg-query -W -f '${Status}\n' 'PKG' 2>&1|awk '/ok installed/{print 0;exit}{print 1}'

or if you prefer the other way around where 1 means installed and 0 otherwise:

dpkg-query -W -f '${Status}\n' 'PKG' 2>&1|awk '/ok installed/{print 1;exit}{print 0}'

** replace PKG with your package name

Convenience function:

installed() {
    return $(dpkg-query -W -f '${Status}\n' "${1}" 2>&1|awk '/ok installed/{print 0;exit}{print 1}')
}

Step1: add permission on android manifest.xml

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

Step2: onCreate() method

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, MY_PERMISSIONS_REQUEST_READ_MEDIA);
    } else {
        readDataExternal();
    }

Step3: override onRequestPermissionsResult method to get callback

 @Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_MEDIA:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                readDataExternal();
            }
            break;

        default:
            break;
    }
}

Note: readDataExternal() is method to get data from external storage.

Thanks.

I think this method my solve your problem:

public static void attachFragment ( int fragmentHolderLayoutId, Fragment fragment, Context context, String tag ) {


    FragmentManager manager = ( (AppCompatActivity) context ).getSupportFragmentManager ();
    FragmentTransaction ft = manager.beginTransaction ();

    if (manager.findFragmentByTag ( tag ) == null) { // No fragment in backStack with same tag..
        ft.add ( fragmentHolderLayoutId, fragment, tag );
        ft.addToBackStack ( tag );
        ft.commit ();
    }
    else {
        ft.show ( manager.findFragmentByTag ( tag ) ).commit ();
    }
}

Use declare

There is no need on using prefixes like on other answers, neither arrays. Use just declare, double quotes, and parameter expansion.

I often use the following trick to parse argument lists contanining one to n arguments formatted as key=value otherkey=othervalue etc=etc, Like:

# brace expansion just to exemplify
for variable in {one=foo,two=bar,ninja=tip}
do
  declare "${variable%=*}=${variable#*=}"
done
echo $one $two $ninja 
# foo bar tip

But expanding the argv list like

for v in "$@"; do declare "${v%=*}=${v#*=}"; done

Extra tips

# parse argv's leading key=value parameters
for v in "$@"; do
  case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
done
# consume argv's leading key=value parameters
while (( $# )); do
  case "$v" in ?*=?*) declare "${v%=*}=${v#*=}";; *) break;; esac
  shift
done

If you want to split a dataframe according to values of some variable, I'd suggest using daply() from the plyr package.

library(plyr)
x <- daply(df, .(splitting_variable), function(x)return(x))

Now, x is an array of dataframes. To access one of the dataframes, you can index it with the name of the level of the splitting variable.

x$Level1
#or
x[["Level1"]]

I'd be sure that there aren't other more clever ways to deal with your data before splitting it up into many dataframes though.

To reiterate a prior solution and to stress the pure CSS implementation here is my answer.

A Pure CSS solution is needed in cases where you are sourcing content from another site, and thus you have no control over the HTML that is delivered. In my case I am trying to remove branding of licensed source content so that the licencee does not have to advertise for the company they are buying the content from. Therefore, I'm removing their logo while keeping everything else. I should note that this is within my client's contract to do so.

{ /* image size is 204x30 */
     width:0;
     height:0;

     padding-bottom:15px;

}

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

If you were using SQL 2012 or above you could use the CONCAT function:

SELECT CONCAT(field1, field2, field3) FROM table1

NULL fields won't break your concatenation.

@bummi - Thanks for the comment - edited my answer to correspond to it.

This answer seems good.
however, it lead me towards an error as it resulted with
Configuration 'xyz' could not be found in project ...
error in build.
It is requierd not only to updated build configurations, but also serve ones.

So just to leave no confusions:

1. --env is not supported in angular 6
2. --env got changed into --configuration || -c (and is now more powerful)
3. to manage various envs, in addition to adding new environment file, it is now required to do some changes in angular.json file:
   • add new configuration in the build { ... "build": "configurations": ... property
   • new build configuration may contain only fileReplacements part, (but more options are available)
   • add new configuration in the serve { ... "serve": "configurations": ... property
   • new serve configuration shall contain of browserTarget="your-project-name:build:staging"

The following is my configuration:

cmake_minimum_required(VERSION 2.8)
set(Boost_INCLUDE_DIR /usr/local/src/boost_1_46_1)
set(Boost_LIBRARY_DIR /usr/local/src/boost_1_46_1/stage/lib)
find_package(Boost COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})

add_executable(main main.cpp)
target_link_libraries( main ${Boost_LIBRARIES} )

This is an excellent article : http://www.daniweb.com/software-development/computer-science/threads/13488/time-complexity-of-algorithm

The below answer is copied from above (in case the excellent link goes bust)

The most common metric for calculating time complexity is Big O notation. This removes all constant factors so that the running time can be estimated in relation to N as N approaches infinity. In general you can think of it like this:

statement;

Is constant. The running time of the statement will not change in relation to N.

for ( i = 0; i < N; i++ )
     statement;

Is linear. The running time of the loop is directly proportional to N. When N doubles, so does the running time.

for ( i = 0; i < N; i++ ) {
  for ( j = 0; j < N; j++ )
    statement;
}

Is quadratic. The running time of the two loops is proportional to the square of N. When N doubles, the running time increases by N * N.

while ( low <= high ) {
  mid = ( low + high ) / 2;
  if ( target < list[mid] )
    high = mid - 1;
  else if ( target > list[mid] )
    low = mid + 1;
  else break;
}

Is logarithmic. The running time of the algorithm is proportional to the number of times N can be divided by 2. This is because the algorithm divides the working area in half with each iteration.

void quicksort ( int list[], int left, int right )
{
  int pivot = partition ( list, left, right );
  quicksort ( list, left, pivot - 1 );
  quicksort ( list, pivot + 1, right );
}

Is N * log ( N ). The running time consists of N loops (iterative or recursive) that are logarithmic, thus the algorithm is a combination of linear and logarithmic.

In general, doing something with every item in one dimension is linear, doing something with every item in two dimensions is quadratic, and dividing the working area in half is logarithmic. There are other Big O measures such as cubic, exponential, and square root, but they're not nearly as common. Big O notation is described as O ( <type> ) where <type> is the measure. The quicksort algorithm would be described as O ( N * log ( N ) ).

Note that none of this has taken into account best, average, and worst case measures. Each would have its own Big O notation. Also note that this is a VERY simplistic explanation. Big O is the most common, but it's also more complex that I've shown. There are also other notations such as big omega, little o, and big theta. You probably won't encounter them outside of an algorithm analysis course. ;)

Another easy way to execute a ps script from batch is to simply incorporate it between the ECHO and the Redirection characters,(> and >>), example:

@echo off
set WD=%~dp0
ECHO New-Item -Path . -Name "Test.txt" -ItemType "file" -Value "This is a text string." -Force > "%WD%PSHELLFILE.ps1"
ECHO add-content -path "./Test.txt" -value "`r`nThe End" >> "%WD%PSHELLFILE.ps1"
powershell.exe -ExecutionPolicy Bypass -File "%WD%PSHELLFILE.ps1"
del "%WD%PSHELLFILE.ps1"

Last line deletes the created temp file.

You could use /* begin comment and end it with */

Or you can simply use // across each line (not recommended)

/*
Here is an article you could of read that tells you all about how to comment
on multiple lines too!:

[http://java.sun.com/docs/codeconv/html/CodeConventions.doc4.html][1]
*/

The way I like to do this is using the %x literal, which makes it easy (and readable!) to use quotes in a command, like so:

directorylist = %x[find . -name '*test.rb' | sort]

Which, in this case, will populate file list with all test files under the current directory, which you can process as expected:

directorylist.each do |filename|
  filename.chomp!
  # work with file
end

Try using BindingExpression.UpdateTarget()

Let me offer a more extensive answer considering things that you haven't mentioned as yet but will find useful.

For your current problem the answer is

$("div[id^='editDialog']");

The caret (^) is taken from regular expressions and means starts with.

Solution 1

// Select elems where 'attribute' ends with 'Dialog'
$("[attribute$='Dialog']"); 

// Selects all divs where attribute is NOT equal to value    
$("div[attribute!='value']"); 

// Select all elements that have an attribute whose value is like
$("[attribute*='value']"); 

// Select all elements that have an attribute whose value has the word foobar
$("[attribute~='foobar']"); 

// Select all elements that have an attribute whose value starts with 'foo' and ends
//  with 'bar'
$("[attribute^='foo'][attribute$='bar']");

attribute in the code above can be changed to any attribute that an element may have, such as href, name, id or src.

Solution 2

Use classes

// Matches all items that have the class 'classname'
$(".className");

// Matches all divs that have the class 'classname'
$("div.className");

Solution 3

List them (also noted in previous answers)

$("#id1,#id2,#id3");

Solution 4

For when you improve, regular expression (Never actually used these, solution one has always been sufficient, but you never know!

// Matches all elements whose id takes the form editDialog-{one_or_more_integers}
$('div').filter(function () {this.id.match(/editDialog\-\d+/)});

[I understand this is an old thread, just adding some more detail] The two answers by Mark and Jon Hanna sum up the differences, albeit it may interest some that

Guid.NewGuid()

Eventually calls CoCreateGuid (a COM call to Ole32) (reference here) and the actual work is done by UuidCreate.

Guid.Empty is meant to be used to check if a Guid contains all zeroes. This could also be done via comparing the value of the Guid in question with new Guid()

So, if you need a unique identifier, the answer is Guid.NewGuid()

Consider using more_itertools.unzip:

>>> from more_itertools import unzip
>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> [list(x) for x in unzip(original)]
[['a', 'b', 'c', 'd'], [1, 2, 3, 4]]     

Disclaimer: I first wrote this and then stumbled upon this question. I thought this solution wasn't yet posted, and saw that tlwhitec did post a similar answer. Still I'm posting this because I hope it's a useful and thorough explanation.

Short answer:

This seems quite a portable solution, as it works on quite some shells (see comment).
This way you can get a real newline into a variable.

The benefit of this solution is that you don't have to use newlines in your source code, so you can indent your code any way you want, and the solution still works. This makes it robust. It's also portable.

# Robust way to put a real newline in a variable (bash, dash, ksh, zsh; indentation-resistant).
nl="$(printf '\nq')"
nl=${nl%q}

Longer answer:

Explanation of the above solution:

The newline would normally lost due to command substitution, but to prevent that, we add a 'q' and remove it afterwards. (The reason for the double quotes is explained further below.)

We can prove that the variable contains an actual newline character (0x0A):

printf '%s' "$nl" | hexdump -C
00000000  0a  |.|
00000001

(Note that the '%s' was needed, otherwise printf will translate a literal '\n' string into an actual 0x0A character, meaning we would prove nothing.)

Of course, instead of the solution proposed in this answer, one could use this as well (but...):

nl='
'

... but that's less robust and can be easily damaged by accidentally indenting the code, or by forgetting to dedent it afterwards, which makes it inconvenient to use in (indented) functions, whereas the earlier solution is robust.

Now, as for the double quotes:
The reason for the double quotes " surrounding the command substitution as in nl="$(printf '\nq')" is that you can then even prefix the variable assignment with the local keyword or builtin (such as in functions), and it will still work on all shells, whereas otherwise the dash shell would have trouble, in the sense that dash would otherwise lose the 'q' and you'd end up with an empty 'nl' variable (again, due to command substitution).
That issue is better illustrated with another example:

dash_trouble_example() {
    e=$(echo hello world) # Not using 'local'.
    echo "$e" # Fine. Outputs 'hello world' in all shells.

    local e=$(echo hello world) # But now, when using 'local' without double quotes ...:
    echo "$e" # ... oops, outputs just 'hello' in dash,
              # ... but 'hello world' in bash and zsh.

    local f="$(echo hello world)" # Finally, using 'local' and surrounding with double quotes.
    echo "$f" # Solved. Outputs 'hello world' in dash, zsh, and bash.

    # So back to our newline example, if we want to use 'local', we need
    # double quotes to surround the command substitution:
    # (If we didn't use double quotes here, then in dash the 'nl' variable
    # would be empty.)
    local nl="$(printf '\nq')"
    nl=${nl%q}
}

Practical example of the above solution:

# Parsing lines in a for loop by setting IFS to a real newline character:

nl="$(printf '\nq')"
nl=${nl%q}

IFS=$nl

for i in $(printf '%b' 'this is line 1\nthis is line 2'); do
    echo "i=$i"
done

# Desired output:
# i=this is line 1
# i=this is line 2

# Exercise:
# Try running this example without the IFS=$nl assignment, and predict the outcome.

Call this function when ready to validate what ever. I used a textbox here

In my HTML:

<input type="button" value="Check IT!" onclick="check(document.getElementById('inputboxToValidate').value);" />

In my JavaScript code:

function check(num){
    var onlynumbers = true
    for (var i = 0; i < (num.length - 1); i++) {
        if (num.substr(i, 1) != "0" || num.substr(i, 1) != "1" || num.substr(i, 1) != "2" || num.substr(i, 1) != "3" || num.substr(i, 1) != "4" || num.substr(i, 1) != "5" || num.substr(i, 1) != "6" || num.substr(i, 1) != "7" || num.substr(i, 1) != "8" || num.substr(i, 1) != "9") {
            alert("please make sure that only numbers have been entered in the Quantaty box");
            onlynumbers = false
        }
    }
    if (onlynumbers == true) {

        //Execute Code
    }
}

You can get it using the :selected selector, like this:

$("#my_select").change(function() {
  var id = $(this).children(":selected").attr("id");
});

Thanks for some great answers. Nothing original to add, but here are some progressive rewrites of qneill's answer using some useful Python facilities. I hope you agree they simplify and clarify the code.

        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc))


def qneill_decode(key, enc):

enumerate()-- pair the items in a list with their index

iterate over the characters in a string

def encode_enumerate(key, clear):

build lists using a list comprehension

def encode_comprehension(key, clear):

Often in Python there's no need for list indexes at all. Eliminate loop index variables entirely using zip and cycle:

from itertools import cycle


def encode_zip_cycle(key, clear):
    enc = [chr((ord(clear_char) + ord(key_char)) % 256)
                for clear_char, key_char in zip(clear, cycle(key))]
    return base64.urlsafe_b64encode("".join(enc))


def decode_zip_cycle(key, enc):
    enc = base64.urlsafe_b64decode(enc)
    dec = [chr((256 + ord(enc_char) - ord(key_char)) % 256)
                for enc_char, key_char in zip(enc, cycle(key))]
    return "".join(dec)

and some tests...

msg = 'The quick brown fox jumps over the lazy dog.'
key = 'jMG6JV3QdtRh3EhCHWUi'
print('cleartext: {0}'.format(msg))
print('ciphertext: {0}'.format(encode_zip_cycle(key, msg)))

git clone https://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts

instead of:

You want to use a JFileChooser object. It will open and be modal, and block in the thread that opened it until you choose a file.

Open:

JFileChooser fileChooser = new JFileChooser();
if (fileChooser.showOpenDialog(modalToComponent) == JFileChooser.APPROVE_OPTION) {
  File file = fileChooser.getSelectedFile();
  // load from file
}

Save:

JFileChooser fileChooser = new JFileChooser();
if (fileChooser.showSaveDialog(modalToComponent) == JFileChooser.APPROVE_OPTION) {
  File file = fileChooser.getSelectedFile();
  // save to file
}

There are more options you can set to set the file name extension filter, or the current directory. See the API for the javax.swing.JFileChooser for details. There is also a page for "How to Use File Choosers" on Oracle's site:

The first argument to nonrecursivecountcells() doesn't have a variable name. You try to reference it as grid in the function body, so you probably want to call it grid.

Apps can’t be deleted if they are part of a Game Center group, in an app bundle, or currently displayed on a store. You’ll want to remove the app from sale or from the group if you want to delete it.

Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;

Here is an overview in a table format in order to show the differences between Pool.apply, Pool.apply_async, Pool.map and Pool.map_async. When choosing one, you have to take multi-args, concurrency, blocking, and ordering into account:

                  | Multi-args   Concurrence    Blocking     Ordered-results
---------------------------------------------------------------------
Pool.map          | no           yes            yes          yes
Pool.map_async    | no           yes            no           yes
Pool.apply        | yes          no             yes          no
Pool.apply_async  | yes          yes            no           no
Pool.starmap      | yes          yes            yes          yes
Pool.starmap_async| yes          yes            no           no

Notes:

• Pool.imap and Pool.imap_async – lazier version of map and map_async.

• Pool.starmap method, very much similar to map method besides it acceptance of multiple arguments.

• Async methods submit all the processes at once and retrieve the results once they are finished. Use get method to obtain the results.

• Pool.map(or Pool.apply)methods are very much similar to Python built-in map(or apply). They block the main process until all the processes complete and return the result.

Examples:

map

Is called for a list of jobs in one time

results = pool.map(func, [1, 2, 3])

apply

Can only be called for one job

for x, y in [[1, 1], [2, 2]]:
    results.append(pool.apply(func, (x, y)))

def collect_result(result):
    results.append(result)

map_async

Is called for a list of jobs in one time

pool.map_async(func, jobs, callback=collect_result)

apply_async

Can only be called for one job and executes a job in the background in parallel

for x, y in [[1, 1], [2, 2]]:
    pool.apply_async(worker, (x, y), callback=collect_result)

starmap

Is a variant of pool.map which support multiple arguments

pool.starmap(func, [(1, 1), (2, 1), (3, 1)])

starmap_async

A combination of starmap() and map_async() that iterates over iterable of iterables and calls func with the iterables unpacked. Returns a result object.

pool.starmap_async(calculate_worker, [(1, 1), (2, 1), (3, 1)], callback=collect_result)

JSON-js - JSON in JavaScript.

To convert an object to a string, use JSON.stringify:

var json_text = JSON.stringify(your_object, null, 2);

To convert a JSON string to object, use JSON.parse:

var your_object = JSON.parse(json_text);

It was recently recommended by John Resig:

...PLEASE start migrating your JSON-using applications over to Crockford's json2.js. It is fully compatible with the ECMAScript 5 specification and gracefully degrades if a native (faster!) implementation exists.

In fact, I just landed a change in jQuery yesterday that utilizes the JSON.parse method if it exists, now that it has been completely specified.

I tend to trust what he says on JavaScript matters :)

All modern browsers (and many older ones which aren't ancient) support the JSON object natively. The current version of Crockford's JSON library will only define JSON.stringify and JSON.parse if they're not already defined, leaving any browser native implementation intact.

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

Just add a new datafile for the existing tablespace

ALTER TABLESPACE LEGAL_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;

To find out the location and size of your data files:

SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA';

I think what BrandonS wants is not the position of the mouse relative to the root element, but rather the position of some descendant element.

For that, there is the TransformToAncestor method:

Point relativePoint = myVisual.TransformToAncestor(rootVisual)
                              .Transform(new Point(0, 0));

Where myVisual is the element that was just double-clicked, and rootVisual is Application.Current.MainWindow or whatever you want the position relative to.

I had this same problem on RHEL6. It turns out that the mysql.ini file in /etc/php.d only had a module name but needed a full path name. On my RHEL6 system the entry that works is:

; Enable mysql extension module

extension=/usr/lib64/php/modules/mysql.so

After modifying the file, I restarted apache and everything worked.

Solution posted by Denys S. in the question post:

I quite messed it up with c to c++ conversion (basically env variable stuff), but I got it working with the following code for C++:

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

jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){

    jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
    jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
    jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
    jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);

    const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
    printf("%s\n", str);

    return (*env)->NewStringUTF(env, str);
}

And next code for java methods:

    public class MainActivity extends Activity {
    private static String LIB_NAME = "thelib";

    static {
        System.loadLibrary(LIB_NAME);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = (TextView) findViewById(R.id.textview);
        tv.setText(this.getJniString());
    }

    // please, let me live even though I used this dark programming technique
    public String messageMe(String text) {
        System.out.println(text);
        return text;
    }

    public native String getJniString();
}

here is my solution!

The way to get the selection of the spinner is:

  spinner1.getSelectedItemPosition();

Documentation reference: http://developer.android.com/reference/android/widget/AdapterView.html#getSelectedItemPosition()

However, in your code, the one place you are referencing it is within your setOnItemSelectedListener(). It is not necessary to poll the spinner, because the onItemSelected method gets passed the position as the "position" variable.

So you could change that line to:

TestProjectActivity.this.number = position + 1;

If that does not fix the problem, please post the error message generated when your app crashes.

Update: 04/2018: Note that Vincenty distance is deprecated since GeoPy version 1.13 - you should use geopy.distance.distance() instead!

The answers above are based on the Haversine formula, which assumes the earth is a sphere, which results in errors of up to about 0.5% (according to help(geopy.distance)). Vincenty distance uses more accurate ellipsoidal models such as WGS-84, and is implemented in geopy. For example,

import geopy.distance

coords_1 = (52.2296756, 21.0122287)
coords_2 = (52.406374, 16.9251681)

print geopy.distance.vincenty(coords_1, coords_2).km

will print the distance of 279.352901604 kilometers using the default ellipsoid WGS-84. (You can also choose .miles or one of several other distance units).

Though its really long back this question was posted, I wish to answer as it might help others. This can be done easily by means of JOINKEYS in a SINGLE step. Here goes the pseudo code:

• Code JOINKEYS PAIRED(implicit) and get both the records via reformatting filed. If there is NO match from either of files then append/prefix some special character say '$'
• Compare via IFTHEN for '$', if exists then it doesnt have a paired record, it'll be written into unpaired file and rest to paired file.

Please do get back incase of any questions.

Following code prints names of classes in specified namespace defined in current assembly.
As other guys pointed out, a namespace can be scattered between different modules, so you need to get a list of assemblies first.

string nspace = "...";

var q = from t in Assembly.GetExecutingAssembly().GetTypes()
        where t.IsClass && t.Namespace == nspace
        select t;
q.ToList().ForEach(t => Console.WriteLine(t.Name));

Code it like this:

PreparedStatement pstmt = con.prepareStatement(
    "SELECT * FROM analysis WHERE notes like ?");
pstmt.setString(1, notes + "%");`

Make sure that you DO NOT include the quotes ' ' like below as they will cause an exception.

pstmt.setString(1,"'%"+ notes + "%'");

i agree with you about alternative solutions which you mentioned above

1. Use POST instead of GET;
2. Transform the List into a JSON string and pass it to the service.

and its true that you can't add List to MultiValuedMap because of its impl class MultivaluedMapImpl have capability to accept String Key and String Value. which is shown in following figure

still you want to do that things than try following code.

Controller Class

package net.yogesh.test;

import java.util.List;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;

import com.google.gson.Gson;

@Path("test")
public class TestController {
       @Path("testMethod")
       @GET
       @Produces("application/text")
       public String save(
               @QueryParam("list") List<String> list) {

           return  new Gson().toJson(list) ;
       }
}

Client Class

public class Client {
    public static void main(String[] args) {
        String op = doGet("http://localhost:8080/JerseyTest/rest/test/testMethod");
        System.out.println(op);
    }

    private static String doGet(String url){
        List<String> list = new ArrayList<String>();
        list = Arrays.asList(new String[]{"string1,string2,string3"});

        MultivaluedMap<String, String> params = new MultivaluedMapImpl();
        String lst = (list.toString()).substring(1, list.toString().length()-1);
        params.add("list", lst);

        ClientConfig config = new DefaultClientConfig();
        com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config);
        WebResource resource = client.resource(url);

        ClientResponse response = resource.queryParams(params).type("application/x-www-form-urlencoded").get(ClientResponse.class);
        String en = response.getEntity(String.class);
        return en;
    }
}

hope this'll help you.

To execute your command directly from within C#, you would use the SqlCommand class.

Quick sample code using paramaterized SQL (to avoid injection attacks) might look like this:

string queryString = "SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName, tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = @tPatSName";
string connectionString = "Server=.\PDATA_SQLEXPRESS;Database=;User Id=sa;Password=2BeChanged!;";

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand command = new SqlCommand(queryString, connection);
    command.Parameters.AddWithValue("@tPatSName", "Your-Parm-Value");
    connection.Open();
    SqlDataReader reader = command.ExecuteReader();
    try
    {
        while (reader.Read())
        {
            Console.WriteLine(String.Format("{0}, {1}",
            reader["tPatCulIntPatIDPk"], reader["tPatSFirstname"]));// etc
        }
    }
    finally
    {
        // Always call Close when done reading.
        reader.Close();
    }
}

in swift 5 we do like, Use typealias for the completion. Typlealias nothing just use to clean the code.

typealias response = (Bool,Any?)->()


static func postCall(_ url : String, param : [String : Any],completion : @escaping response){
    Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: [:]).responseJSON { (response) in

        switch response.result {
           case .success(let JSON):
               print("\n\n Success value and JSON: \(JSON)")

           case .failure(let error):
               print("\n\n Request failed with error: \(error)")

           }
    }
}

Yes, you can use the native javascript Date() object and its methods.

For instance you can create a function like:

function formatDate(date) {
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return (date.getMonth()+1) + "/" + date.getDate() + "/" + date.getFullYear() + "  " + strTime;
}

var d = new Date();
var e = formatDate(d);

alert(e);

And display also the am / pm and the correct time.

Remember to use getFullYear() method and not getYear() because it has been deprecated.

DEMO http://jsfiddle.net/a_incarnati/kqo10jLb/4/

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

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

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

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

  public static bool isnull(object T)
  {
      return T == null ? true : false;
  }

use:

isnull(object.check.it)

Conditional use:

isnull(object.check.it) ? DoWhenItsTrue : DoWhenItsFalse;

Update (another way) updated 08/31/2017 and 01/25/2021. Thanks for the comment.

public static bool IsNull(object T)
{
    return (bool)T ? true : false;
}

Demostration

And for the records, you have my code on Github, go check it out: https://github.com/j0rt3g4/ValidateNull PS: This one is especially for you Chayim Friedman, don't use beta software assuming that is all true. Wait for final versions or use your own environment to test, before assuming true beta software without any sort of documentation or demonstration from your end.

I had this same problem with a datalist I"m dynamically binding, adding EnableViewState="false" quieted the error message. I figure if I'm binding programmatically, then the control is being populated on each post back, the view state doesn't have to be maintained if it may or may not change on each call back, that's why I'm dynamically binding it, lol.

While correct that this will work:

TimeSpan time = TimeSpan.Parse("07:35");

And if you are using it for validation...

TimeSpan time;
if (!TimeSpan.TryParse("07:35", out time))
{
    // handle validation error
}

Consider that TimeSpan is primarily intended to work with elapsed time, rather than time-of-day. It will accept values larger than 24 hours, and will accept negative values also.

If you need to validate that the input string is a valid time-of-day (>= 00:00 and < 24:00), then you should consider this instead:

DateTime dt;
if (!DateTime.TryParseExact("07:35", "HH:mm", CultureInfo.InvariantCulture, 
                                              DateTimeStyles.None, out dt))
{
    // handle validation error
}
TimeSpan time = dt.TimeOfDay;

As an added benefit, this will also parse 12-hour formatted times when an AM or PM is included, as long as you provide the appropriate format string, such as "h:mm tt".

Another nice way to put your logic in data is something like this:

# Initialization.
CAR_TYPES = {
  foo_type: ['honda', 'acura', 'mercedes'],
  bar_type: ['toyota', 'lexus']
  # More...
}
@type_for_name = {}
CAR_TYPES.each { |type, names| names.each { |name| @type_for_name[type] = name } }

case @type_for_name[car]
when :foo_type
  # do foo things
when :bar_type
  # do bar things
end

Adding some information here that I experienced:

fragment.isVisible is only working (true/false) when you replaceFragment() otherwise if you work with addFragment(), isVisible always returns true whether the fragment is in behind of some other fragment.

git checkout <target_branch>
git checkout <source_branch> <file_path>

android:imeActionLabel="Done" 
android:singleLine="true"

In the XML file works just fine. But this will also cause the editText to keep typing in a single line which you may not want. So adding following to your code will make sure that you won't end up typing everything on a single line.

mainText.setHorizontallyScrolling(false);
mainText.setMaxLines("Maximum integer value that you want to provide");

Just install the updated versions of all of them.

apt-get install -y gnupg2 gnupg gnupg1

To be short, use:

write-output "your text" | out-file -append -encoding utf8 "filename"

One more way is::

Write a method in your adapter lets say public void callBack(){}.

Now while creating an object for adapter in activity override this method. Override method will be called when you call the method in adapter.

Myadapter adapter = new Myadapter() {
  @Override
  public void callBack() {
    // dosomething
  }
};

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

maybe

string = document.location.href;
arrayOfStrings = string.toString().split('/');

assuming you want the current url

This works for me:

git rm -r --cached --ignore-unmatch folder_name

--ignore-unmatch is important here, without that option git will exit with error on the first file not in the index.

Raymond Chen has a few ideas:

https://devblogs.microsoft.com/oldnewthing/20050128-00/?p=36573

Quoted here in full because MSDN archives tend to be somewhat unreliable:

The easy way is to use the %CD% pseudo-variable. It expands to the current working directory.

set OLDDIR=%CD%
.. do stuff ..
chdir /d %OLDDIR% &rem restore current directory

(Of course, directory save/restore could more easily have been done with pushd/popd, but that's not the point here.)

The %CD% trick is handy even from the command line. For example, I often find myself in a directory where there's a file that I want to operate on but... oh, I need to chdir to some other directory in order to perform that operation.

set _=%CD%\curfile.txt
cd ... some other directory ...
somecommand args %_% args

(I like to use %_% as my scratch environment variable.)

Type SET /? to see the other pseudo-variables provided by the command processor.

Also the comments in the article are well worth scanning for example this one (via the WayBack Machine, since comments are gone from older articles):

http://blogs.msdn.com/oldnewthing/archive/2005/01/28/362565.aspx#362741

This covers the use of %~dp0:

If you want to know where the batch file lives: %~dp0

%0 is the name of the batch file. ~dp gives you the drive and path of the specified argument.

Inspired by this very post, I now use a handy function,
reproduce(<mydata>) when I need to post to StackOverflow.

QUICK INSTRUCTIONS

If myData is the name of your object to reproduce, run the following in R:

install.packages("devtools")
library(devtools)
source_url("https://raw.github.com/rsaporta/pubR/gitbranch/reproduce.R")

reproduce(myData)

Details:

This function is an intelligent wrapper to dput and does the following:

• Automatically samples a large data set (based on size and class. Sample size can be adjusted)
• Creates a dput output
• Allows you to specify which columns to export
• Appends to the front of it objName <- ... so that it can be easily copy+pasted, but...
• If working on a mac, the output is automagically copied to the clipboard, so that you can simply run it and then paste it to your question.

The source is available here:

• Github - pubR/reproduce.R

Example:

# sample data
DF <- data.frame(id=rep(LETTERS, each=4)[1:100], replicate(100, sample(1001, 100)), Class=sample(c("Yes", "No"), 100, TRUE))

DF is about 100 x 102. I want to sample 10 rows and a few specific columns

reproduce(DF, cols=c("id", "X1", "X73", "Class"))  # I could also specify the column number. 

Gives the following output:

This is what the sample looks like: 

    id  X1 X73 Class

Notice also that the entirety of the output is in a nice single, long line, not a tall paragraph of chopped up lines. This makes it easier to read on SO questions posts and also easier to copy+paste.

Update Oct 2013:

You can now specify how many lines of text output will take up (ie, what you will paste into StackOverflow). Use the lines.out=n argument for this. Example:

reproduce(DF, cols=c(1:3, 17, 23), lines.out=7) yields:

Now in FileZilla, create a new Account 1. Host is the FTP Address - e.g. ftp.somewhere.com 2. Protocol is "SFTP-SSH File Transfer Protocol" 3. User ID is your Bluehost User Id 4. Password is your Bluehost Password 5. Click "Connect" to establish a connection with Directory Listing!

This resolve the issue with 3.10 for me. And I'm glad to have the Secure Access for all of my future file transfers. It should prevent security issues in the future.

Use the built-in localized formats

If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk, HH nor hh. I suggest that you use something like this:

    DateTimeFormatter defaultTimeFormatter
            = DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
    System.out.format("%s: %s%n",
            Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));

The point is that it gives different output in different default locales. For example:

en_SS: 12:00 AM
fr_BL: 00:00
ps_AF: 0:00
es_CO: 12:00 a.m.

The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.

I furthermore suggest that you don’t use SimpleDateFormat. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.

Four pattern letters for hour: H, h, k and K

Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):

  Symbol  Meaning                     Presentation      Examples
  ------  -------                     ------------      -------
   h       clock-hour-of-am-pm (1-12)  number            12
   K       hour-of-am-pm (0-11)        number            0
   k       clock-hour-of-day (1-24)    number            24
   H       hour-of-day (0-23)          number            0

In practice H and h are used. As far as I know k and K are not (they may just have been included for the sake of completeness). But let’s just see them all in action:

    DateTimeFormatter timeFormatter
            = DateTimeFormatter.ofPattern("hh:mm a  HH:mm  kk:mm  KK:mm a", Locale.ENGLISH);
    System.out.println(LocalTime.of(0, 0).format(timeFormatter));
    System.out.println(LocalTime.of(1, 15).format(timeFormatter));
    System.out.println(LocalTime.of(11, 25).format(timeFormatter));
    System.out.println(LocalTime.of(12, 35).format(timeFormatter));
    System.out.println(LocalTime.of(13, 40).format(timeFormatter));

12:00 AM  00:00  24:00  00:00 AM
01:15 AM  01:15  01:15  01:15 AM
11:25 AM  11:25  11:25  11:25 AM
12:35 PM  12:35  12:35  00:35 PM
01:40 PM  13:40  13:40  01:40 PM

If you don’t want the leading zero, just specify one pattern letter, that is h instead of hh or H instead of HH. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.

In simply words, somehow the following is happening:

render() {
    return (
        <MyComponent /> // MyComponent is undefined.
    );
}

It may not necessarily be related with some incorrect import or export:

render() {
    // MyComponent may be undefined here, for example.
    const MyComponent = this.wizards[this.currentStep];

    return (
        <MyComponent />
    );
}

Most browsers don't display the custom message passed to confirm().

With this method, you can show a popup with a custom message if your user changed the value of any <input> field.

You can apply this only to some links, or even other HTML elements in your page. Just add a custom class to all the links that need confirmation and apply use the following code:

$(document).ready(function() {_x000D_
  let unsaved = false;_x000D_
  // detect changes in all input fields and set the 'unsaved' flag_x000D_
  $(":input").change(() => unsaved = true);_x000D_
  // trigger popup on click_x000D_
  $('.dangerous-link').click(function() {_x000D_
    if (unsaved && !window.confirm("Are you sure you want to nuke the world?")) {_x000D_
      return; // user didn't confirm_x000D_
    }_x000D_
    // either there are no unsaved changes or the user confirmed_x000D_
    window.location.href = $(this).data('destination');_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<input type="text" placeholder="Nuclear code here" />_x000D_
<a data-destination="https://en.wikipedia.org/wiki/Boom" class="dangerous-link">_x000D_
    Launch nuke!_x000D_
</a>

Try changing the input value in the example to get a preview of how it works.

x += 5 is not exactly the same as saying x = x + 5 in Python.

Note here:

In [1]: x = [2, 3, 4]    
In [2]: y = x    
In [3]: x += 7, 8, 9    
In [4]: x
Out[4]: [2, 3, 4, 7, 8, 9]    
In [5]: y
Out[5]: [2, 3, 4, 7, 8, 9]    
In [6]: x += [44, 55]    
In [7]: x
Out[7]: [2, 3, 4, 7, 8, 9, 44, 55]    
In [8]: y
Out[8]: [2, 3, 4, 7, 8, 9, 44, 55]    
In [9]: x = x + [33, 22]    
In [10]: x
Out[10]: [2, 3, 4, 7, 8, 9, 44, 55, 33, 22]    
In [11]: y
Out[11]: [2, 3, 4, 7, 8, 9, 44, 55]

See for reference: Why does += behave unexpectedly on lists?

It's significantly easier to do this in Angular 6 than it was in previous versions, even when the checkbox information is populated asynchronously from an API.

The first thing to realise is that thanks to Angular 6's keyvalue pipe we don't need to have to use FormArray anymore, and can instead nest a FormGroup.

First, pass FormBuilder into the constructor

constructor(
    private _formBuilder: FormBuilder,
) { }

Then initialise our form.

ngOnInit() {

    this.form = this._formBuilder.group({
        'checkboxes': this._formBuilder.group({}),
    });

}

When our checkbox options data is available, iterate it and we can push it directly into the nested FormGroup as a named FormControl, without having to rely on number indexed lookup arrays.

const checkboxes = <FormGroup>this.form.get('checkboxes');
options.forEach((option: any) => {
    checkboxes.addControl(option.title, new FormControl(true));
});

Finally, in the template we just need to iterate the keyvalue of the checkboxes: no additional let index = i, and the checkboxes will automatically be in alphabetical order: much cleaner.

<form [formGroup]="form">

    <h3>Options</h3>

    <div formGroupName="checkboxes">

        <ul>
            <li *ngFor="let item of form.get('checkboxes').value | keyvalue">
                <label>
                    <input type="checkbox" [formControlName]="item.key" [value]="item.value" /> {{ item.key }}
                </label>
            </li>
        </ul>

    </div>

</form>

If you are looking to copy all the text files in one folder to merge and copy to another folder, you can do this to achieve that:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace HowToCopyTextFiles
{
  class Program
  {
    static void Main(string[] args)
    {
      string mydocpath=Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);     
      StringBuilder sb = new StringBuilder();
      foreach (string txtName in Directory.GetFiles(@"D:\Links","*.txt"))
      {
        using (StreamReader sr = new StreamReader(txtName))
        {
          sb.AppendLine(txtName.ToString());
          sb.AppendLine("= = = = = =");
          sb.Append(sr.ReadToEnd());
          sb.AppendLine();
          sb.AppendLine();   
        }
      }
      using (StreamWriter outfile=new StreamWriter(mydocpath + @"\AllTxtFiles.txt"))
      {    
        outfile.Write(sb.ToString());
      }   
    }
  }
}

document.getElementById('Id').value='new value';

Update April 2019

Changelong for JAXB releases is at https://javaee.github.io/jaxb-v2/doc/user-guide/ch02.html

excerpts:

    4.1. Changes between 2.3.0.1 and 2.4.0

         JAXB RI is now JPMS modularized:

            All modules have native module descriptor.

            Removed jaxb-core module, which caused split package issue on JPMS.

            RI binary bundle now has single jar per dependency instead of shaded fat jars.

            Removed runtime class weaving optimization.

    4.2. Changes between 2.3.0 and 2.3.0.1

          Removed legacy technology dependencies:

            com.sun.xml.bind:jaxb1-impl

            net.java.dev.msv:msv-core

            net.java.dev.msv:xsdlib

            com.sun.xml.bind.jaxb:isorelax

    4.3. Changes between 2.2.11 and 2.3.0

          Adopt Java SE 9:

            JAXB api can now be loaded as a module.

            JAXB RI is able to run on Java SE 9 from the classpath.

            Addes support for java.util.ServiceLoader mechanism.

            Security fixes

Maven coordinates for JAXB artifacts

jakarta.xml.bind:jakarta.xml.bind-api: API classes for JAXB. Required to compile against JAXB.

org.glassfish.jaxb:jaxb-runtime: Implementation of JAXB, runtime used for serialization and deserialization java objects to/from xml.

JAXB fat-jar bundles:

com.sun.xml.bind:jaxb-impl: JAXB runtime fat jar.

In contrast to org.glassfish.jaxb artifacts, these jars have all dependency classes included inside. These artifacts does not contain JPMS module descriptors. In Maven projects org.glassfish.jaxb artifacts are supposed to be used instead.

Original Answer

Following Which artifacts should I use for JAXB RI in my Maven project? in Maven, you can use a profile like:

<profile>
    <id>java-9</id>
    <activation>
        <jdk>9</jdk>
    </activation>
    <dependencies>
        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>javax.activation</groupId>
            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>
    </dependencies>
</profile> 

Dependency tree shows:

[INFO] +- org.glassfish.jaxb:jaxb-runtime:jar:2.3.0:compile
[INFO] |  +- org.glassfish.jaxb:jaxb-core:jar:2.3.0:compile

To use this in Eclipse, say Oxygen.3a Release (4.7.3a) or later, Ctrl-Alt-P, or right-click on the project, Maven, then select the profile.

I solved my 'foreign key constraint fails' issues by adding the following code to the start of the SQL code (this was for importing values to a table)

SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT;
SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS;
SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION;
SET NAMES utf8;
SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO';
SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0; 

Then adding this code to the end of the file

SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;
SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT;
SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS;
SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION;
SET SQL_NOTES=@OLD_SQL_NOTES;

While it looks like your setup is correct, there are a few things to check:

1. The output of env - specifically PATH.
2. command -v java tells you what?
3. Is there a java executable in $JAVA_HOME\bin and does it have the execute bit set? If not chmod a+x java it.

I trust you have source'd your .profile after adding/changing the JAVA_HOME and PATH?

Also, you can help yourself in future maintenance of your JDK installation by writing this instead:

export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=$JAVA_HOME/bin:$PATH

Then you only need to update one env variable when you setup the JDK installation.

Finally, you may need to run hash -r to clear the Bash program cache. Other shells may need a similar command.

See creating a registry key.

This problem can occur not only due to permissions, but also due to event source key missing because it wasn't registered successfully (you need admin privileges to do it - if you just open Visual Studio as usual and run the program normally it won't be enough). Make sure that your event source "MyApp" is actually registered, i.e. that it appears in the registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application.

From MSDN EventLog.CreateEventSource():

To create an event source in Windows Vista and later or Windows Server 2003, you must have administrative privileges.

So you must either run the event source registration code as an admin (also, check if the source already exists before - see the above MSDN example) or you can manually add the key to the registry:

1. create a regkey HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\MyApp;
2. inside, create a string value EventMessageFile and set its value to e.g. C:\Windows\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll

Try to create script with ADD command and specification of working directory Like this("script" is the name of script and /root/script.sh is where you want it in the container, it can be different path:

ADD script.sh /root/script.sh

In this case ADD has to come before CMD, if you have one BTW it's cool way to import scripts to any location in container from host machine

In CMD place [./script]

It should automatically execute your script

You can also specify WORKDIR as /root, then you'l be automatically placed in root, upon starting a container

Code:

var select = function(dropdown, selectedValue) {
    var options = $(dropdown).find("option");
    var matches = $.grep(options,
        function(n) { return $(n).text() == selectedValue; });
    $(matches).attr("selected", "selected");
};

Example:

select("#dropdown", "B");

One more reason to occurrence of these errors is unexpected whitespace like similar characters with-in code, the code lines seems to be perfect, but they contains some specific characters which are similar to break line or whitespace or tab but they not get parsed by the parser. I face this issue when I try to put some code from webpage to the code editor by simply copy paste, I saw this error with array definition. everything was looking right in array definition. I can't sort out right error, finally I define this array in single line, then error was gone. then again I try to make that definition multiple like but manually adding break(Enter) for each array element and saved the file this time no parsing error by editor and also no error while running it. For Example I faced issue with this snippet which was on one blog, actually can't post those snippets ,cause stack overflow already knows the problem with code.

then after solving it my working snippet is, which looks similar with one which shows parsing error

syntax error, unexpected ''auth'' (T_CONSTANT_ENCAPSED_STRING), expecting ']'

    public $aliases = [
        'csrf'=> \CodeIgniter\Filters\CSRF::class,
        'toolbar'=> \CodeIgniter\Filters\DebugToolbar::class,
        'honeypot'=> \CodeIgniter\Filters\Honeypot::class,
        'auth' => \App\Filters\Auth::class,
];

Tab is [HT], or character number 9, in the unicode library.

My guess would be to check that the mysqli extension is enabled in your PHP configuration. More info would be great (eg. OS, AMP stack, etc.).

Check in your php.ini configuration for mysqli and make sure there is no ';' in front of the extension. The one enabled on my setup is php_mysqli_libmysql.dll.

DataSet resembles database. DataTable resembles database table, and DataRow resembles a record in a table. If you want to add filtering or sorting options, you then do so with a DataView object, and convert it back to a separate DataTable object.

If you're using database to store your data, then you first load a database table to a DataSet object in memory. You can load multiple database tables to one DataSet, and select specific table to read from the DataSet through DataTable object. Subsequently, you read a specific row of data from your DataTable through DataRow. Following codes demonstrate the steps:

SqlCeDataAdapter da = new SqlCeDataAdapter();
DataSet ds = new DataSet();
DataTable dt = new DataTable();

da.SelectCommand = new SqlCommand(@"SELECT * FROM FooTable", connString);
da.Fill(ds, "FooTable");
dt = ds.Tables["FooTable"];

foreach (DataRow dr in dt.Rows)
{
    MessageBox.Show(dr["Column1"].ToString());
}

To read a specific cell in a row:

int rowNum // row number
string columnName = "DepartureTime";  // database table column name
dt.Rows[rowNum][columnName].ToString();

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);

Use this function which suits every situation.

CREATE FUNCTION dbo.fnNumPadLeft (@input INT, @pad tinyint)
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @NumStr VARCHAR(250)

    SET @NumStr = LTRIM(@input)

    IF(@pad > LEN(@NumStr))
        SET @NumStr = REPLICATE('0', @Pad - LEN(@NumStr)) + @NumStr;

    RETURN @NumStr;
END

Sample output

SELECT [dbo].[fnNumPadLeft] (2016,10) -- returns 0000002016
SELECT [dbo].[fnNumPadLeft] (2016,5) -- returns 02016
SELECT [dbo].[fnNumPadLeft] (2016,2) -- returns 2016
SELECT [dbo].[fnNumPadLeft] (2016,0) -- returns 2016 

Did you try formatting the entire column as a date column? Something like this:

Range rg = (Excel.Range)worksheetobject.Cells[1,1];
rg.EntireColumn.NumberFormat = "MM/DD/YYYY";

The other thing you could try would be putting a single tick before the string expression before loading the text into the Excel cell (not sure if that matters or not, but it works when typing text directly into a cell).

Just use memcpy.

If the destination isn't big enough, strncpy won't null terminate. if the destination is huge compared to the source, strncpy just fills the destination with nulls after the string. strncpy is pointless, and unsuitable for copying strings.

strncpy is like memcpy except it fills the destination with nulls once it sees one in the source. It's absolutely useless for string operations. It's for fixed with 0 padded records.

Eric Sink from SourceGear wrote series of articles on differences between distributed and nondistributed version controls systems. He compares pros and cons of most popular version control systems. Very interesting reading.

In rare cases (e.g., after a heavy transaction is commited) a running CHECKPOINT system process holding a FILE lock on the database file prevents transition to MULTI_USER mode.

You should accept Mike Gossland's answer, but it can be improved a little. Try this in Git Bash:

 ls -1F /bin | grep '\*$' | grep -v '\.dll\*$' | sed 's/\*$\|\.exe//g'

Explanation:

List on 1 line, decorated with trailing * for executables, all files in bin. Keep only those with the trailing *s, but NOT ending with .dll*, then replace all ending asterisks or ".exe" with nothing.

This gives you a clean list of all the GitBash commands.

I ended up using the following.

Regarding Firefox comment(s): Generally, Firefox will not show any text placeholder for inputs type date. But as this is a Cordova/PhoneGap question this should be of no concern (Unless you want to develop against FirefoxOS).

input[type="date"]:not(.has-value):before{_x000D_
  color: lightgray;_x000D_
  content: attr(placeholder);_x000D_
}

<input type="date" placeholder="MY PLACEHOLDER" onchange="this.className=(this.value!=''?'has-value':'')">

After trying all of this solutions, I still had different problems. So what I found the simplest way was to create a python file: config.py, with a dictionary containing the file's absolute path and import it into the script. something like

import config as cfg 
import pandas as pd 
pd.read_csv(cfg.paths['myfilepath'])

where config.py has inside:

paths = {'myfilepath': 'home/docs/...'}

It is not automatic but it is a good solution when you have to work in different directory or different machines.

To test a scenario with a void method like

void testMeWell() throws SomeException {..}

to not throw an exception:

Junit5

assertDoesNotThrow(() -> {
    testMeWell();
});

This will list Everything (including sub directories) from the directory you specify, in order, and with the attributes. I have spent days looking for something to do this, and I took parts from this entire discussion, and a little of my own, and put it together. ENJOY!!

A PDB file contains information used by the debugger. It is not required to run your application and it does not need to be included in your released version.

You can disable pdb files from being created in Visual Studio. If you are building from the command line or a script then omit the /Debug switch.

I found it easier to edit the project file directly e.g. YourApp.csproj.

You can do this by modifying ApplicationIcon property element:

<ApplicationIcon>..\Path\To\Application.ico</ApplicationIcon>

Also, if you create an MSI installer for your application e.g. using WiX, you can use the same icon again for display in Add/Remove Programs. See tip 5 here.

My solution was creating a project with Use legacy support library option checked. after the project creation is successfully completed, just delete the src folder in the app directory and copy the src folder from your main project. Finally, Sync project with Gradle files.

If you are using Postegres and Rails 4+, then you have the option of using column type CITEXT, which will allow case insensitive queries without having to write out the query logic.

The migration:

def change
  enable_extension :citext
  change_column :products, :name, :citext
  add_index :products, :name, unique: true # If you want to index the product names
end

And to test it out you should expect the following:

Product.create! name: 'jOgGers'
=> #<Product id: 1, name: "jOgGers">

Product.find_by(name: 'joggers')
=> #<Product id: 1, name: "jOgGers">

Product.find_by(name: 'JOGGERS')
=> #<Product id: 1, name: "jOgGers">

Have you tried the GNU make documentation? It has a whole section about conditionals with examples.

ok just to answer the original question:

you can get the padding as a usable integer like this:

var padding = parseInt($("myId").css("padding-top").replace("ems",""));

If you have defined another measurement like px just replace "ems" with "px". parseInt interprets the stringpart as a wrong value so its important to replace it with ... nothing.

For Visual Studio 2019 you may not find Project -> Add Reference option. Use Project -> Add Project Reference. Then in dialog window navigate to Browse tab and use Browse to find and attach your dll.

Rename File using VB SCript.

1. Create Folder Source and Archive in D : Drive. [You can choose other drive but make change in code from D:\Source to C:\Source in case you create folder in C: Drive]
2. Save files in Source folder to be renamed.
3. Save below code and save it as .vbs e.g ChangeFileName.vbs

4. Run file and the file will be renamed with existing file name and current date

   Option Explicit

The accepted answer is the correct way to do this in most cases. However, there are some situations where you want to set the cookie header manually. Normally if you set a "Cookie" header it is ignored, but that's because HttpClientHandler defaults to using its CookieContainer property for cookies. If you disable that then by setting UseCookies to false you can set cookie headers manually and they will appear in the request, e.g.

var baseAddress = new Uri("http://example.com");
using (var handler = new HttpClientHandler { UseCookies = false })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
    var message = new HttpRequestMessage(HttpMethod.Get, "/test");
    message.Headers.Add("Cookie", "cookie1=value1; cookie2=value2");
    var result = await client.SendAsync(message);
    result.EnsureSuccessStatusCode();
}

Yes, div can take as many classes as you need. Use space to separate one from another.

Edit #2 ( 7/2/2017)

If you install the angular cli right now, you'd probably have the new name of angular cli which is @angular/cli, so you need to uninstall it using

npm uninstall -g @angular/cli

and follow the code above. I'm still getting upvotes for this so I updated my answer for those who want to use the older version for some reasons.

Edit #1

If you really want to create a new project with previous version of Angular using the cli, try to downgrade the angular-cli before the final release. Something like:

npm uninstall -g angular-cli
npm cache clean
npm install -g [email protected]

Initial

You can change the version of the angular in the package.json . I'm guessing you want to use older version of angular but I suggest you use the latest version. Using:

ng new app-name

will always use the latest version of angular.

You could put the text into a div (or other container) with a width of 50%.

Yea, java is Garbage collected, it will delete the memory for you.

Works - Add Spacing To Table

#options table {

This is the updated code for findOneAndUpdate. It works.

db.collection.findOneAndUpdate(    
  { age: 17 },      
  { $set: { name: "Naomi" } },

     returnNewDocument: true
  }

Map<K,V> is an interface, HashMap<K,V> is a class that implements Map.

you can do

Map<Key,Value> map = new HashMap<Key,Value>();

Here you have a link to the documentation of each one: Map, HashMap.

Try this:

item.shipping!==undefined

AppDomain.CurrentDomain.BaseDirectory is probably the most useful for accessing files whose location is relative to the application install directory.

In an ASP.NET application, this will be the application root directory, not the bin subfolder - which is probably what you usually want. In a client application, it will be the directory containing the main executable.

In a VSTO 2005 application, it will be the directory containing the VSTO managed assemblies for your application, not, say, the path to the Excel executable.

The others may return different directories depending on your environment - for example see @Vimvq1987's answer.

CodeBase is the place where a file was found and can be a URL beginning with http://. In which case Location will probably be the assembly download cache. CodeBase is not guaranteed to be set for assemblies in the GAC.

UPDATE These days (.NET Core, .NET Standard 1.3+ or .NET Framework 4.6+) it's better to use AppContext.BaseDirectory rather than AppDomain.CurrentDomain.BaseDirectory. Both are equivalent, but multiple AppDomains are no longer supported.

If you want to create a "desired" Guid you can do

var tempGuid = Guid.Parse("<guidValue>");

where <guidValue> would be something like 1A3B944E-3632-467B-A53A-206305310BAE.

Now the class is this

 <img src="img/img5.jpg" width="200px" class="rounded-circle float-right">

As others have said, you can use the dependency:analyze goal to find which dependencies are used and declared, used and undeclared, or unused and declared. You may also find dependency:analyze-dep-mgt useful to look for mismatches in your dependencyManagement section.

You can simply remove unwanted direct dependencies from your POM, but if they are introduced by third-party jars, you can use the <exclusions> tags in a dependency to exclude the third-party jars (see the section titled Dependency Exclusions for details and some discussion). Here is an example excluding commons-logging from the Spring dependency:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring</artifactId>
  <version>2.5.5</version>
  <exclusions>
    <exclusion>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </exclusion>
  </exclusions> 
</dependency>

Add this to your code:

.child { width: 100%; }

We know that a block-level child is supposed to occupy the full width of the parent.

Chrome understands this.

IE11, for whatever reason, wants an explicit request.

Using flex-basis: 100% or flex: 1 also works.

.parent {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  width: 400px;_x000D_
  border: 1px solid red;_x000D_
  align-items: center;_x000D_
}_x000D_
.child {_x000D_
  border: 1px solid blue;_x000D_
  width: calc(100% - 2px);       /* NEW; used calc to adjust for parent borders */_x000D_
}

<div class="parent">_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_
</div>

Note: Sometimes it will be necessary to sort through the various levels of the HTML structure to pinpoint which container gets the width: 100%. CSS wrap text not working in IE

You said that you can’t use HTML comments because the CMS filters them out. So I assume that you really want to hide this content and you don’t need to display it ever.

In that case, you shouldn’t use CSS (only), as you’d only play on the presentation level, not affecting the content level. Your content should also be hidden for user-agents ignoring the CSS (people using text browsers, feed readers, screen readers; bots; etc.).

In HTML5 there is the global hidden attribute:

When specified on an element, it indicates that the element is not yet, or is no longer, directly relevant to the page's current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user. User agents should not render elements that have the hidden attribute specified.

Example (using the small element here, because it’s an "attribution"):

<small hidden>Thanks to John Doe for this idea.</small>

As a fallback (for user-agents that don’t know the hidden attribute), you can specify in your CSS:

[hidden] {display:none;}

An general element for plain text could be the script element used as "data block":

<script type="text/plain" hidden>
Thanks to John Doe for this idea.
</script>

Alternatively, you could also use data-* attributes on existing elements (resp. on new div elements if you want to group some elements for the attribution):

<p data-attribution="Thanks to John Doe for this idea!">This is some visible example content …</p>

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

Simply place this line in your Model:

public $timestamps = false;

And that's it!

Example:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    public $timestamps = false;

    //
}

To disable timestamps for one operation (e.g. in a controller):

$post->content = 'Your content'; 
$post->timestamps = false; // Will not modify the timestamps on save
$post->save();

To disable timestamps for all of your Models, create a new BaseModel file:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BaseModel extends Model
{
    public $timestamps = false;

    //
}

Then extend each one of your Models with the BaseModel, like so:

<?php

namespace App;

class Post extends BaseModel
{
    //
}

As of currently (September 2014) I would recommend using NSInteger/CGFloat when interacting with iOS API's etc if you are also building your app for arm64. This is because you will likely get unexpected results when you use the float, long and int types.

EXAMPLE: FLOAT/DOUBLE vs CGFLOAT

As an example we take the UITableView delegate method tableView:heightForRowAtIndexPath:.

In a 32-bit only application it will work fine if it is written like this:

-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 44;
}

float is a 32-bit value and the 44 you are returning is a 32-bit value. However, if we compile/run this same piece of code in a 64-bit arm64 architecture the 44 will be a 64-bit value. Returning a 64-bit value when a 32-bit value is expected will give an unexpected row height.

You can solve this issue by using the CGFloat type

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 44;
}

This type represents a 32-bit float in a 32-bit environment and a 64-bit double in a 64-bit environment. Therefore when using this type the method will always receive the expected type regardless of compile/runtime environment.

The same is true for methods that expect integers. Such methods will expect a 32-bit int value in a 32-bit environment and a 64-bit long in a 64-bit environment. You can solve this case by using the type NSInteger which serves as an int or a long based on the compile/runtime environemnt.

Take a look at JQuery view engine and just load the array into a dropdown:

$.ajax({
    url:'suggest.html',
    type:'POST',
    data: 'q=' + str,
    dataType: 'json',
    success: function( json ) {
          // Assumption is that API returned something like:["North","West","South","East"];
          $('#myselect').view(json);
    }
});

I don't think it's possible to do it in the way you are trying to do it.

Indication of the accepted data format is usually done through adding the extension to the resource name. So, if you have resource like

/resources/resource

and GET /resources/resource returns its HTML representation, to indicate that you want its XML representation instead, you can use following pattern:

/resources/resource.xml

You have to do the accepted content type determination magic on the server side, then.

Or use Javascript as James suggests.

Make sure that the database is created. I got the same error when I applied the migration to the wrong project in the solution. When I applied the migration to the right project, it created the database and that solved the error.

Under "Settings -> Editor -> General -> Auto Import" there are several options regarding automatic imports. Only unambiguous imports may be added automatically; this is one of the options.

I usually use a function to validate my post and it is an answer for this question too so let me post it.

to call my function I will use the 2 array like this

validatePost(['username', 'password', 'any other field'], $_POST))

then my function will look like this

 function validatePost($requiredFields, $post)
    {
        $validation = [];

        foreach($requiredFields as $required => $key)
        {
            if(!array_key_exists($key, $post))
            {
                $validation['required'][] = $key;
            }
        }

        return $validation;
    }

this will output this

"required": [ "username", "password", "any other field" ]

so what this function does is validate and return all the missing fields of the post request.

Most probably, you didn't install any SQL Server Engine service. If no SQL Server engine is installed, no service will appear in the SQL Server Configuration Manager tool. Consider that the packages SQLManagementStudio_Architecture_Language.exe and SQLEXPR_Architecture_Language.exe, available in the Microsoft site contain, respectively only the Management Studio GUI Tools and the SQL Server engine.

If you want to have a full featured SQL Server installation, with the database engine and Management Studio, download the installer file of SQL Server with Advanced Services. Moreover, to have a sample database in order to perform some local tests, use the Adventure Works database.

Considering the package of SQL Server with Advanced Services, at the beginning at the installation you should see something like this (the screenshot below is about SQL Server 2008 Express, but the feature selection is very similar). The checkbox next to "Database Engine Services" must be checked. In the next steps, you will be able to configure the instance settings and other options.

Execute again the installation process and select the database engine services in the feature selection step. At the end of the installation, you should be able to see the SQL Server services in the SQL Server Configuration Manager.

From PythonTR - Python Programcilari Dernegi, e-kitap, örnek:

Process p = new Process();   // Create new object
p.StartInfo.UseShellExecute = false;  // Do not use shell
p.StartInfo.RedirectStandardOutput = true;   // Redirect output
p.StartInfo.FileName = "c:\\python26\\python.exe";   // Path of our Python compiler
p.StartInfo.Arguments = "c:\\python26\\Hello_C_Python.py";   // Path of the .py to be executed

I was able to achieve the desired result by using Alt + Shift + up/down and then typing the desired comment characters and additional character.

You can try it by adding  

Webpack does support multiple output paths.

Set the output paths as the entry key. And use the name as output template.

webpack config:

entry: {
    'module/a/index': 'module/a/index.js',
    'module/b/index': 'module/b/index.js',
},
output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].js'
}

generated:

+-- module
    +-- a
    ¦   +-- index.js
    +-- b
        +-- index.js

At the time of this writing, there is no official support for TensorFlow with Python 3.6 on Windows. The recommendation is to build TensorFlow yourself.

Some people have already done this and provide *.whl files that you can directly install with pip. These are unofficial, so use at your own risk:

• http://www.lfd.uci.edu/%7Egohlke/pythonlibs/#tensorflow

You can simply download them and install them with pip install <filename>.whl.

See also this GitHub comment.

There are probably some commands to resolve it, but I would start by looking in your .git/config file for references to that branch, and removing them.

setState is asynchronous. You can see in this documentation by Reactjs

• https://reactjs.org/docs/faq-state.html#why-is-setstate-giving-me-the-wrong-valuejs
• https://reactjs.org/docs/faq-state.html#when-is-setstate-asynchronous

React intentionally “waits” until all components call setState() in their event handlers before starting to re-render. This boosts performance by avoiding unnecessary re-renders.

However, you might still be wondering why React doesn’t just update this.state immediately without re-rendering.

The reason is this would break the consistency between props and state, causing issues that are very hard to debug.

You can still perform functions if it is dependent on the change of the state value:

Option 1: Using callback function with setState

this.setState({
   value: newValue
},()=>{
   // It is an callback function.
   // Here you can access the update value
   console.log(this.state.value)
})

Option 2: using componentDidUpdate This function will be called whenever the state of that particular class changes.

componentDidUpdate(prevProps, prevState){
    //Here you can check if value of your desired variable is same or not.
    if(this.state.value !== prevState.value){
        // this part will execute if your desired variable updates
    }
}

Javascript in a browser only really has a couple of effective scopes: function scope and global scope.

If a variable isn't in function scope, it's in global scope. And global variables are generally bad, so this is a construct to keep a library's variables to itself.

System.out.println(char1+""+char2+char3)

or

String s = char1+""+char2+char3;

You can accomplish this by playing with the opacity of the image and setting the background color of the image to black. By making the image transparent, it will appear darker.

<div class="image">
    <img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
</div> 

CSS:

.image { position: relative; border: 1px solid black; width: 200px; height: 200px; background: black; }
.image img { max-width: 100%; max-height: 100%; }
.image img:hover { opacity: .5 }

You might need to set the browser-specific opacity too to make this work in other browsers too.

The big thing to get your head around is that the File class tries to represent a view of what Sun like to call "hierarchical pathnames" (basically a path like c:/foo.txt or /usr/muggins). This is why you create files in terms of paths. The operations you are describing are all operations upon this "pathname".

• getPath() fetches the path that the File was created with (../foo.txt)
• getAbsolutePath() fetches the path that the File was created with, but includes information about the current directory if the path is relative (/usr/bobstuff/../foo.txt)
• getCanonicalPath() attempts to fetch a unique representation of the absolute path to the file. This eliminates indirection from ".." and "." references (/usr/foo.txt).

Note I say attempts - in forming a Canonical Path, the VM can throw an IOException. This usually occurs because it is performing some filesystem operations, any one of which could fail.

HTTP Servers tend to reject old browsers and systems.

The page Tech Blog (wh): Most Common User Agents reflects the user-agent property of your current browser in section "Your user agent is:", which can be applied to set the request property "User-Agent" of a java.net.URLConnection or the system property "http.agent".

Instead of early binding the reference, there's an open source project called NetOffice that abstracts this from your project, making life much easier. That way you don't have to rely on your users having a specific version of Office installed.

This is for Larave 5.2.x and greater. If you want to have an option to serve some content over HTTPS and others over HTTP here is a solution that worked for me. You may wonder, why would someone want to serve only some content over HTTPS? Why not serve everything over HTTPS?

Although, it's totally fine to serve the whole site over HTTPS, severing everything over HTTPS has an additional overhead on your server. Remember encryption doesn't come cheap. The slight overhead also has an impact on your app response time. You could argue that commodity hardware is cheap and the impact is negligible but I digress :) I don't like the idea of serving marketing content big pages with images etc over https. So here it goes. It's similar to what others have suggest above using middleware but it's a full solution that allows you to toggle back and forth between HTTP/HTTPS.

First create a middleware.

php artisan make:middleware ForceSSL

This is what your middleware should look like.

<?php

namespace App\Http\Middleware;

use Closure;

class ForceSSL
{

    public function handle($request, Closure $next)
    {

        if (!$request->secure()) {
            return redirect()->secure($request->getRequestUri());
        }

        return $next($request);
    }
}

Note that I'm not filtering based on environment because I have HTTPS setup for both local dev and production so there is not need to.

Add the following to your routeMiddleware \App\Http\Kernel.php so that you can pick and choose which route group should force SSL.

    protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'forceSSL' => \App\Http\Middleware\ForceSSL::class,
];

Next, I'd like to secure two basic groups login/signup etc and everything else behind Auth middleware.

Route::group(array('middleware' => 'forceSSL'), function() {
/*user auth*/
Route::get('login', 'AuthController@showLogin');
Route::post('login', 'AuthController@doLogin');

// Password reset routes...
Route::get('password/reset/{token}', 'Auth\PasswordController@getReset');
Route::post('password/reset', 'Auth\PasswordController@postReset');

//other routes like signup etc

});


Route::group(['middleware' => ['auth','forceSSL']], function()
 {
Route::get('dashboard', function(){
    return view('app.dashboard');
});
Route::get('logout', 'AuthController@doLogout');

//other routes for your application
});

Confirm that your middlewares are applied to your routes properly from console.

php artisan route:list

Now you have secured all the forms or sensitive areas of your application, the key now is to use your view template to define your secure and public (non https) links.

Based on the example above you would render your secure links as follows -

<a href="{{secure_url('/login')}}">Login</a>
<a href="{{secure_url('/signup')}}">SignUp</a>

Non secure links can be rendered as

<a href="{{url('/aboutus',[],false)}}">About US</a></li>
<a href="{{url('/promotion',[],false)}}">Get the deal now!</a></li>

What this does is renders a fully qualified URL such as https://yourhost/login and http://yourhost/aboutus

If you were not render fully qualified URL with http and use a relative link url('/aboutus') then https would persists after a user visits a secure site.

Hope this helps!

Some might encounter this error either locally or on the server:

syntax error var data = new google.visualization.DataTable(<?=$jsonTable?>);

This means that their environment does not support short tags the solution is to use this instead:

<?php echo $jsonTable; ?>

And everything should work fine!

As @0x499602d2 already pointed out, const only ensures that a value cannot be changed after initialization where as constexpr (introduced in C++11) guarantees the variable is a compile time constant.
Consider the following example(from LearnCpp.com):

cout << "Enter your age: ";
int age;
cin >> age;

const int myAge{age};        // works
constexpr int someAge{age};  // error: age can only be resolved at runtime

Size of some float types may exceed the size of int. This example shows a safe conversion of any float type to int using the int safeFloatToInt(const FloatType &num); function:

#include <iostream>
#include <limits>
using namespace std;

template <class FloatType>
int safeFloatToInt(const FloatType &num) {
   //check if float fits into integer
   if ( numeric_limits<int>::digits < numeric_limits<FloatType>::digits) {
      // check if float is smaller than max int
      if( (num < static_cast<FloatType>( numeric_limits<int>::max())) &&
          (num > static_cast<FloatType>( numeric_limits<int>::min())) ) {
         return static_cast<int>(num); //safe to cast
      } else {
        cerr << "Unsafe conversion of value:" << num << endl;
        //NaN is not defined for int return the largest int value
        return numeric_limits<int>::max();
      }
   } else {
      //It is safe to cast
      return static_cast<int>(num);
   }
}
int main(){
   double a=2251799813685240.0;
   float b=43.0;
   double c=23333.0;
   //unsafe cast
   cout << safeFloatToInt(a) << endl;
   cout << safeFloatToInt(b) << endl;
   cout << safeFloatToInt(c) << endl;
   return 0;
}

Result:

Unsafe conversion of value:2.2518e+15
2147483647
43
23333

This solution works fine :

$("body")   .on('click'     ,'[data-toggle="popover"]', function(e) { 
    e.stopPropagation();
});

$("body")   .on('click'     ,'.popover' , function(e) { 
     e.stopPropagation();
});

$("body")   .on('click'  , function(e) {
        $('[data-toggle="popover"]').popover('hide');
});

I've created a video tutorial for this. Just check:

Connect to Amazon EC2 file directory using FileZilla and SFTP, Video Tutorial

Summary of above video tutorial:

1. Edit (Preferences) > Settings > Connection > SFTP, Click "Add key file”
2. Browse to the location of your .pem file and select it.
3. A message box will appear asking your permission to convert the file into ppk format. Click Yes, then give the file a name and store it somewhere.
4. If the new file is shown in the list of Keyfiles, then continue to the next step. If not, then click "Add keyfile..." and select the converted file.

5. File > Site Manager Add a new site with the following parameters:

   Host: Your public DNS name of your EC2 instance, or the public IP address of the server.

   Protocol: SFTP

   Logon Type: Normal

   User: From the docs: "For Amazon Linux, the default user name is ec2-user. For RHEL5, the user name is often root but might be ec2-user. For Ubuntu, the user name is ubuntu. For SUSE Linux, the user name is root. For Debian, the user name is admin. Otherwise, check with your AMI provider."

   Press Connect Button - If saving of passwords has been disabled, you will be prompted that the logon type will be changed to 'Ask for password'. Say 'OK' and when connecting, at the password prompt push 'OK' without entering a password to proceed past the dialog.

   Note: FileZilla automatically figures out which key to use. You do not need to specify the key after importing it as described above.

If you use Cyberduck follow this.

Check this post if you have any permission issues.

If you're doing this in your erb view (for Rails), be mindful of the <% and <%= differences. What you'd want is:

<% (1..x).each do |i| %>
  Code to display using <%= stuff %> that you want to display    
<% end %>

For plain Ruby, you can refer to: http://www.tutorialspoint.com/ruby/ruby_loops.htm

Another way of getting the results

SELECT * from table WHERE SUBSTRING(tester, 1, 8)  <> 'username' or tester is null

try to drop the firewall on your laptop and see if there is difference. Maybe Your laptop is firewall blocking some broadcasts that prevents local network name resolution.

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

I solved it this way:

• Settings ->
• Apps ->
• All Apps ->
• Google Play Store ->
• Delete Cache ->
• Force Stop ->
• Google Services Framework ->
• Delete Data ->
• Force Stop

Then restart your device. Now enjoy...

It's 100% working.

The behaviour should depend on how the browser is set up to handle various MIME types. In this case the MIME type is application/pdf. If you want to force the browser to download the file you can try forcing a different MIME type on the PDF files. I recommend against this as it should be the users choice what will happen when they open a PDF file.

This is the same as the other answers, but uses only one label and puts the usage first, which additionally makes it serve as a kind of documentation commend of the script which is also usually placed at the top:

@echo off
:: add other test for the arguments here...
if not [%1]==[] goto main
:: --------------------------
echo This command does something.
echo.
echo %0 param%%1 param%%2
echo       param%%1 the file to operate on
echo       param%%1 another file

:: --------------------------
exit /B 1

:main
:: --------------------------
echo do something with all arguments (%%* == %*) here...

However, if you don't have to use cmd/batch, use bash on WSL or powershell, they have more sane syntax and less arcane features.

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.

1. [ChildActionOnly] allowing restricted access via code in View

2. State Information implementation for specific page URL. Example: Payment Page URL (paying only once) razor syntax allows to call specific actions conditional

I just planned to share some knowledge.

Deadlocks A set of threads/processes is deadlocked, if each thread/process in the set is waiting for an event that only another process in the set can cause.

The important thing here is another process is also in the same set. that means another process also blocked and no one can proceed.

Deadlocks occur when processes are granted exclusive access to resources.

These four conditions should be satisfied to have a deadlock.

1. Mutual exclusion condition (Each resource is assigned to 1 process)
2. Hold and wait condition (Process holding resources and at the same time it can ask other resources).
3. No preemption condition (Previously granted resources can not forcibly be taken away) #This condition depends on the application
4. Circular wait condition (Must be a circular chain of 2 or more processes and each is waiting for resource held by the next member of the chain) # It will happen dynamically

If we found these conditions then we can say there may be occurred a situation like a deadlock.

LiveLock

Each thread/process is repeating the same state again and again but doesn't progress further. Something similar to a deadlock since the process can not enter the critical section. However in a deadlock, processes are wait without doing anything but in livelock, the processes are trying to proceed but processes are repeated to the same state again and again.

(In a deadlocked computation there is no possible execution sequence which succeeds. but In a livelocked computation, there are successful computations, but there are one or more execution sequences in which no process enters its critical section.)

Difference from deadlock and livelock

When deadlock happens, No execution will happen. but in livelock, some executions will happen but those executions are not enough to enter the critical section.

So I made this ..kind of game.. based on this post (using msvcr library and Python 3.7).

The following is the "main function" of the game, that is detecting the keys pressed:

# Requiered libraries - - - -
import msvcrt
# - - - - - - - - - - - - - -


def _secret_key(self):
    # Get the key pressed by the user and check if he/she wins.

    bk = chr(10) + "-"*25 + chr(10)

    while True:

        print(bk + "Press any key(s)" + bk)
        #asks the user to type any key(s)

        kp = str(msvcrt.getch()).replace("b'", "").replace("'", "")
        # Store key's value.

        if r'\xe0' in kp:
            kp += str(msvcrt.getch()).replace("b'", "").replace("'", "")
            # Refactor the variable in case of multi press.

        if kp == r'\xe0\x8a':
            # If user pressed the secret key, the game ends.
            # \x8a is CTRL+F12, that's the secret key.

            print(bk + "CONGRATULATIONS YOU PRESSED THE SECRET KEYS!\a" + bk)
            print("Press any key to exit the game")
            msvcrt.getch()
            break
        else:
            print("    You pressed:'", kp + "', that's not the secret key(s)\n")
            if self.select_continue() == "n":
                if self.secondary_options():
                    self._main_menu()
                break

If you want the full source code of the porgram you can see it or download it from here:

The Secret Key Game (GitHub)

(note: the secret keypress is: Ctrl+F12)

I hope you can serve as an example and help for those who come to consult this information.

Set environment variables and use headers to receive them:

You can create new environment variables with RewriteRule lines, as mentioned by OP:

RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

But if you can't get a server-side script to work, how can you then read this environment variable? One solution is to set a header:

Header set TEST_FOOBAR "%{REDIRECT_TEST0}e"

The value accepts format specifiers, including the %{NAME}e specifier for environment variables (don't forget the lowercase e). Sometimes, you'll need to add the REDIRECT_ prefix, but I haven't worked out when the prefix gets added and when it doesn't.

We were able to solve this problem by adding in the Object.Assign polyfill to the files being imported and throwing the error. We would make it the highest import, that way it would be available to the other code to be called in the stack.

import "mdn-polyfills/Object.assign";

os.Mkdir is used to create a single directory. To create a folder path, instead try using:

os.MkdirAll(folderPath, os.ModePerm)

Go documentation

func MkdirAll(path string, perm FileMode) error

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm are used for all directories that MkdirAll creates. If path is already a directory, MkdirAll does nothing and returns nil.

Edit:

Updated to correctly use os.ModePerm instead.
For concatenation of file paths, use package path/filepath as described in @Chris' answer.

var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";

using (var Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true))
    Key.SetValue(appName, 99999, RegistryValueKind.DWord);

According to what I read here (Controlling WebBrowser Control Compatibility:

What Happens if I Set the FEATURE_BROWSER_EMULATION Document Mode Value Higher than the IE Version on the Client?

Obviously, the browser control can only support a document mode that is less than or equal to the IE version installed on the client. Using the FEATURE_BROWSER_EMULATION key works best for enterprise line of business apps where there is a deployed and support version of the browser. In the case you set the value to a browser mode that is a higher version than the browser version installed on the client, the browser control will choose the highest document mode available.

The simplest thing is to put a very high decimal number ...

you may want to see if your app can run under IronPython. If so, you can compile it to an exe http://www.codeplex.com/IronPython

Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!

A slightly other way of iterating through each column of each line of a CSV-file would be

$path = "d:\scratch\export.csv"
$csv = Import-Csv -path $path

foreach($line in $csv)
{ 
    $properties = $line | Get-Member -MemberType Properties
    for($i=0; $i -lt $properties.Count;$i++)
    {
        $column = $properties[$i]
        $columnvalue = $line | Select -ExpandProperty $column.Name

        # doSomething $column.Name $columnvalue 
        # doSomething $i $columnvalue 
    }
} 

so you have the choice: you can use either $column.Name to get the name of the column, or $i to get the number of the column

If you are using hibernate with JPA annotations then this will be useful. In your service class there should be a setter for entity manager with @PersistenceContext. change this to @PersistenceContext(type = PersistenceContextType.EXTENDED). Then you can access lazy property in any where.

On the version posted by sunshinekitty called "Version < 3.0" , you may need to specify apscheduler 2.1.2 . I accidentally had version 3 on my 2.7 install, so I went:

pip uninstall apscheduler
pip install apscheduler==2.1.2

It worked correctly after that. Hope that helps.

Another possible solution, in case a string is an ASCII string, is to maintain an array of 256 boolean elements to denote ASCII character appearance in a string. If a character appeared for the first time, we keep it and append to the result. Otherwise just skip it.

public String removeDuplicates(String input) {
    boolean[] chars = new boolean[256];
    StringBuilder resultStringBuilder = new StringBuilder();
    for (Character c : input.toCharArray()) {
        if (!chars[c]) {
            resultStringBuilder.append(c);
            chars[c] = true;
        }
    }
    return resultStringBuilder.toString();

This approach will also work with Unicode string. You just need to increase chars size.

The trick of appending "*" can be made to work when the new extension is shorter. You need to pad the new extension with blanks, which can only be done by enclosing the destination file name in quotes. For example:

xcopy foo.shtml "foo.html *"

This will copy and rename without prompting.

"That's not a bug, it's a feature!" (I once saw a VW Beetle in the Microsoft parking lot with the vanity plate "FEATURE".) These semantics for rename go all the way back to when I wrote DOS v.1. Characters in the new name are substituted one by one for characters in the old name, unless a wildcard character (? or *) is present in the new name. Without adding the blank(s) to the new name, remaining characters are copied from the old name.

Even after going through many posts, it took several hours to figure out the problem. Here is the detailed approach written in simple language to run python via command line in windows.

1. Download executable file from python.org
Choose the latest version and download Windows-executable installer. Execute the downloaded file and let installation complete.

2. Ensure the file is downloaded in some administrator folder

1. Search file location of Python application.
2. Right click on the .exe file and navigate to its properties. Check if it is of the form, "C:\Users....". If NO, you are good to go and jump to step 3. Otherwise, clone the Python37 or whatever version you downloaded to one of these locations, "C:\", "C:\Program Files", "C:\Program Files (x86)".
   

3. Update the system PATH variable This is the most crucial step and there are two ways to do this:- (Follow the second one preferably)

1. MANUALLY
- Search for 'Edit the system Environment Variables' in the search bar.(WINDOWS 10)
- In the System Properties dialog, navigate to "Environment Variables".
- In the Environment Variables dialog look for "Path" under the System Variables window. (# Ensure to click on Path under bottom window named System Variables and not under user variables)
- Edit the Path Variable by adding location of Python37/ PythonXX folder. I added following line:-
" ;C:\Program Files (x86)\Python37;C:\Program Files (x86)\Python37\Scripts "
- Click Ok and close the dialogs.

2. SCRIPTED
- Open the command prompt and navigate to Python37/XX folder using cd command.
- Write the following statement:-
"python.exe Tools\Scripts\win_add2path.py"

You can now use python in the command prompt:)
1. Using Shell
Type python in cmd and use it.
2. Executing a .py file
Type python filename.py to execute it.

Surprisingly, all other answers only say half the truth or are actually wrong!

• e.stopImmediatePropagation() stops any further handler from being called for this event, no exceptions
• e.stopPropagation() is similar, but does still call all handlers for this phase on this element if not called already

What phase?

E.g. a click event will always first go all the way down the DOM (called “capture phase”), finally reach the origin of the event (“target phase”) and then bubble up again (“bubble phase”). And with addEventListener() you can register multiple handlers for both capture and bubble phase independently. (Target phase calls handlers of both types on the target without distinguishing.)

And this is what the other answers are incorrect about:

• quote: “event.stopPropagation() allows other handlers on the same element to be executed”
  • correction: if stopped in the capture phase, bubble phase handlers will never be reached, also skipping them on the same element
• quote: “event.stopPropagation() [...] is used to stop executions of its corresponding parent handler only”
  • correction: if propagation is stopped in the capture phase, handlers on any children, including the target aren’t called either, not only parents
  • ...and: if propagation is stopped in the bubble phase, all capture phase handlers have already been called, including those on parents

If you go to your android-sdk/tools folder I think you'll find a message :

The adb tool has moved to platform-tools/

If you don't see this directory in your SDK, launch the SDK and AVD Manager (execute the android tool) and install "Android SDK Platform-tools"

Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.

So you should also add C:/android-sdk/platform-tools to you environment path. Also after you modify the PATH variable make sure that you start a new CommandPrompt window.

split_part() does what you want in one step:

SELECT split_part(col, ',', 1) AS col1
     , split_part(col, ',', 2) AS col2
     , split_part(col, ',', 3) AS col3
     , split_part(col, ',', 4) AS col4
FROM   tbl;

Add as many lines as you have items in col (the possible maximum). Columns exceeding data items will be empty strings ('').

driver.find_element_by_id('foo').clear()

cheeky jquery solution if anyone's interested. Just make sure all your cols (el) have a common classname...works responsively too if you bind it to $(window).resize

function equal_cols(el)
{
    var h = 0;
    $(el).each(function(){
        $(this).css({'height':'auto'});
        if($(this).outerHeight() > h)
        {
            h = $(this).outerHeight();
        }
    });
    $(el).each(function(){
        $(this).css({'height':h});
    });
}

Usage

$(document).ready(function(){
   equal_cols('.selector');
});

Note: This post has been edited as per @Chris' comment out that the code was only set the last highest height in the $.each() function

You can add .a file in the linking command:

  gcc yourfiles /path/to/library/libLIBRARY.a

But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are.

When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library types checked you can use -Wl,-Bstatic and -Wl,-Bdynamic. Here is a man page of gnu LD: http://linux.die.net/man/1/ld

To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:

gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3

Assuming that default setting of ld is to use dynamic libraries (it is on Linux).

i use this:

def extend_string(s, l):
    return (s*l)[:l]

You need to have it converted to a Date, where you can then add a number of seconds, and convert it back to a string.

This is an old thread but I was surprised nobody mentioned grep. The -A option allows specifying a number of lines to print after a search match and the -B option includes lines before a match. The following command would output 10 lines before and 10 lines after occurrences of "my search string" in the file "mylogfile.log":

grep -A 10 -B 10 "my search string" mylogfile.log

If there are multiple matches within a large file the output can rapidly get unwieldy. Two helpful options are -n which tells grep to include line numbers and --color which highlights the matched text in the output.

If there is more than file to be searched grep allows multiple files to be listed separated by spaces. Wildcards can also be used. Putting it all together:

grep -A 10 -B 10 -n --color "my search string" *.log someOtherFile.txt

Taken from the NSString reference, you can use :

NSString *theFileName = [[string lastPathComponent] stringByDeletingPathExtension];

The lastPathComponent call will return thefile.ext, and the stringByDeletingPathExtension will remove the extension suffix from the end.

here's working function

function plus_one_day($date){
 $date2 = formatDate4db($date);
 $date1 = str_replace('-', '/', $date2);
 $tomorrow = date('Y-m-d',strtotime($date1 . "+1 days"));
 return $tomorrow; }

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

I couldn't find a direct GDrive/DropBox solution. I'm also surprised there's no lazy solution for a free ftp host. Windows azure offers a ftp server "FTP connector" that's fairly easy to turn on at: https://portal.azure.com

You can get a free 1 GB account by selecting "View All" machine types during your deployment.

In the jQuery world, if you want to select an object from a set of DOM elements, you should use eq().

Examples:

var button = $('button').eq(1);

or

var button = $('button:eq(1)');

In CSS, FontAwesome unicode works only when the correct font family is declared (version 4 or less):

font-family: "FontAwesome";
content: "\f066";

Update - Version 5 has different names:

Free

font-family: "Font Awesome 5 Free"

Pro

font-family: "Font Awesome 5 Pro"

Brands

font-family: "Font Awesome 5 Brands"
