Programs & Examples On #Itemcommand

-Filter only accepts a single string. -Include accepts multiple values, but qualifies the -Path argument. The trick is to append \* to the end of the path, and then use -Include to select multiple extensions. BTW, quoting strings is unnecessary in cmdlet arguments unless they contain spaces or shell special characters.

Get-ChildItem $originalPath\* -Include *.gif, *.jpg, *.xls*, *.doc*, *.pdf*, *.wav*, .ppt*

Note that this will work regardless of whether $originalPath ends in a backslash, because multiple consecutive backslashes are interpreted as a single path separator. For example, try:

Get-ChildItem C:\\\\\Windows

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

Resolution

To work around this problem, use one of the following methods:

• For Response.End, call the HttpContext.Current.ApplicationInstance.CompleteRequest() method instead of Response.End to bypass the code execution to the Application_EndRequest event.

• For Response.Redirect, use an overload, Response.Redirect(String url, bool endResponse) that passes false for the endResponse parameter to suppress the internal call to Response.End. For example: Response.Redirect ("nextpage.aspx", false); If you use this workaround, the code that follows Response.Redirect is executed.

• For Server.Transfer, use the Server.Execute method instead.

Symptoms

If you use the Response.End, Response.Redirect, or Server.Transfer method, a ThreadAbortException exception occurs. You can use a try-catch statement to catch this exception.

Cause

The Response.End method ends the page execution and shifts the execution to the Application_EndRequest event in the application's event pipeline. The line of code that follows Response.End is not executed.

This problem occurs in the Response.Redirect and Server.Transfer methods because both methods call Response.End internally.

Status

This behavior is by design.

Source: PRB: ThreadAbortException Occurs If You Use Response.End, Response.Redirect, or Server.Transfer

You could try something like this:

...Binding="{Binding RelativeSource={RelativeSource FindAncestor, 
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...

No need to create overload methods, just use one single method with params as shown below

// Call params method with one to four integer constant parameters.
//
int sum0 = addTwoEach();
int sum1 = addTwoEach(1);
int sum2 = addTwoEach(1, 2);
int sum3 = addTwoEach(3, 3, 3);
int sum4 = addTwoEach(2, 2, 2, 2);

Simple and straightforward:

1) Create your recaptcha fields normally with this:

<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>

2) Load the script with this:

<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>

3) Now call this to iterate over the fields and create the recaptchas:

<script type="text/javascript">
  var CaptchaCallback = function() {
    jQuery('.g-recaptcha').each(function(index, el) {
        grecaptcha.render(el, {
            'sitekey' : jQuery(el).attr('data-sitekey')
            ,'theme' : jQuery(el).attr('data-theme')
            ,'size' : jQuery(el).attr('data-size')
            ,'tabindex' : jQuery(el).attr('data-tabindex')
            ,'callback' : jQuery(el).attr('data-callback')
            ,'expired-callback' : jQuery(el).attr('data-expired-callback')
            ,'error-callback' : jQuery(el).attr('data-error-callback')
        });
    });
  };
</script>

If you set the value of a variable inside the function, python understands it as creating a local variable with that name. This local variable masks the global variable.

In your case, Var1 is considered as a local variable, and it's used before being set, thus the error.

To solve this problem, you can explicitly say it's a global by putting global Var1 in you function.

Var1 = 1
Var2 = 0
def function():
    global Var1
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    Var1 =- 1
function()

I had the same problem. It was caused because I compiled the Boost with the Visual C++ 2010(v100) and I tried to use the library with the Visual Studio 2012 (v110) by mistake.

So, I changed the configurations (in Visual Studio 2012) going to Project properties -> General -> Plataform Toolset and change the value from Visual Studio 2012 (v110) to Visual Studio 2010 (v100).

WIth the Help of @excray's comment, I manage to figure it out the answer, What we need to do is actually write a simple for loop to iterate over the two arrays that represent the train data and test data.

First implement a simple lambda function to hold formula for the cosine calculation:

cosine_function = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

And then just write a simple for loop to iterate over the to vector, logic is for every "For each vector in trainVectorizerArray, you have to find the cosine similarity with the vector in testVectorizerArray."

from sklearn.feature_extraction.text import CountVectorizer
from sklearn.feature_extraction.text import TfidfTransformer
from nltk.corpus import stopwords
import numpy as np
import numpy.linalg as LA

train_set = ["The sky is blue.", "The sun is bright."] #Documents
test_set = ["The sun in the sky is bright."] #Query
stopWords = stopwords.words('english')

vectorizer = CountVectorizer(stop_words = stopWords)
#print vectorizer
transformer = TfidfTransformer()
#print transformer

trainVectorizerArray = vectorizer.fit_transform(train_set).toarray()
testVectorizerArray = vectorizer.transform(test_set).toarray()
print 'Fit Vectorizer to train set', trainVectorizerArray
print 'Transform Vectorizer to test set', testVectorizerArray
cx = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

for vector in trainVectorizerArray:
    print vector
    for testV in testVectorizerArray:
        print testV
        cosine = cx(vector, testV)
        print cosine

transformer.fit(trainVectorizerArray)
print
print transformer.transform(trainVectorizerArray).toarray()

transformer.fit(testVectorizerArray)
print 
tfidf = transformer.transform(testVectorizerArray)
print tfidf.todense()

Here is the output:

Fit Vectorizer to train set [[1 0 1 0]
 [0 1 0 1]]
Transform Vectorizer to test set [[0 1 1 1]]
[1 0 1 0]
[0 1 1 1]
0.408
[0 1 0 1]
[0 1 1 1]
0.816

[[ 0.70710678  0.          0.70710678  0.        ]
 [ 0.          0.70710678  0.          0.70710678]]

[[ 0.          0.57735027  0.57735027  0.57735027]]

As far as find BlueBearr response the best (while I,m running my batch script with eg. SYSTEM rights) I have to add something to it. Because in my Windows language version (Polish) line that is to be catched by "%%a %%b"=="User Name:" gets REALLY COMPLICATED (it contains some diacritic characters in my language) I skip first 7 lines and operate on the 8th.

@for /f "SKIP= 7 TOKENS=3,4 DELIMS=\ " %%G in ('tasklist /FI "IMAGENAME eq explorer.exe" /FO LIST /V') do @IF %%G==%COMPUTERNAME% set _currdomain_user=%%H

$r = array("arr1","arr2");

to echo a single array element you should write:

echo $r[0];
echo $r[1];

output would be: arr1 arr2

try out like this

body {
   background: #fff url("!--MIZO-PRO--!") no-repeat center 15px top 15px/100px;
     }


/* 100px is the background size */

You could create a copy of the array and then multiply each element with -1.
As an effect the before largest elements would become the smallest.
The indeces of the n smallest elements in the copy are the n greatest elements in the original.

As far as I know keys and values of a HashMap are not mixed when you represent them as arrays:

hashmap.values().toArray()

and

hashmap.keySet().toArray()

So the following code (since java 8) should work as expected:

public Object getKeyByFirstValue(Object value) {
    int keyNumber =  Arrays.asList(hashmap.values().toArray()).indexOf(value);
    return hashmap.keySet().toArray()[keyNumber];
}

However, (WARNING!) it works 2-3 times slower than iteration.

For your case, you can directly use JPA methods. That is like bellow:

Containing: select ... like %:username%

List<User> findByUsernameContainingIgnoreCase(String username);

here, IgnoreCase will help you to search item with ignoring the case.

Here are some related methods:

1. Like findByFirstnameLike

   … where x.firstname like ?1

2. StartingWith findByFirstnameStartingWith

   … where x.firstname like ?1 (parameter bound with appended %)

3. EndingWith findByFirstnameEndingWith

   … where x.firstname like ?1 (parameter bound with prepended %)

4. Containing findByFirstnameContaining

   … where x.firstname like ?1 (parameter bound wrapped in %)

Hope this will help you :)

In October 2014 the Docker team introduced docker exec command: https://docs.docker.com/engine/reference/commandline/exec/

So now you can run any command in a running container just knowing its ID (or name):

docker exec -it <container_id_or_name> echo "Hello from container!"

Note that exec command works only on already running container. If the container is currently stopped, you need to first run it with the following command:

docker run -it -d shykes/pybuilder /bin/bash

The most important thing here is the -d option, which stands for detached. It means that the command you initially provided to the container (/bin/bash) will be run in the background and the container will not stop immediately.

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

foreach ($array as $value => $name) {
     echo '<option value="' . htmlentities($value) . '"' . (($_GET['sel'] === $value) ? ' selected="selected"') . '>' . htmlentities($name) . '</option>';
}

This is fairly neat, and, I think, self-explanatory.

I would strongly recommend field access and NOT annotations on the getters (property access) if you want to do anything more in the setters than just setting the value (e.g. Encryption or calculation).

The problem with the property access is that the setters are also called when the object is loaded. This has worked for me fine for many month until we wanted to introduce encryption. In our use case we wanted to encrypt a field in the setter and decrypt it in the getter. The problem now with property access was that when Hibernate loaded the object it was also calling the setter to populate the field and thus was encrypting the encrypted value again. This post also mentions this: Java Hibernate: Different property set function behavior depending on who is calling it

This has cause me headaches until I remembered the difference between field access and property access. Now I have moved all my annotations from property access to field access and it works fine now.

According to this: http://www.vistax64.com/vista-installation-setup/33219-regsvr32-error-0x80004005.html

A thing you have to understand first: you have no files.
A file is a subject of a filesystem, but you are making your request using HTTP protocol which supports no files but URLs.

So, you have to request an unexisting file using your browser and see the response code. if it's not 404, you are unable to use any wrappers to see if a file exists and you have to request your cdn using some other protocol, FTP for example

Much like above, using CALL, EXIT /B, SETLOCAL & ENDLOCAL you can implement functions with local variables and return values.

example:

@echo off

set x=xxxxx
call :fun 10
echo "%x%"
echo "%y%"
exit /b

:fun
setlocal
set /a y=%1 + 1
endlocal & set x=%y%
exit /b

This will print:

"11"
""

The y variable never leaves the local scope, but because of the way CMD resolves a single line at a time, you can extract the value into the x variable in the parent scope.

Your app is expecting to find a file at /home/embah/node/nodeapp/config/config.json but that file does not exist (which is what ENOENT means). So you either need to create the expected directory structure or else configure your application such that it looks in the correct directory for config.json.

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

In addition to above I had to remove C:\Users\%USERNAME%\AppData\Roaming\npm also. This helped.

You can use Ra-Ajax and have an iframe wrapped inside e.g. a Window control. Though in general terms I don't encourage people to use iframes (for anything)

Another alternative is to load the HTML on the server and send it directly into the Window as the content of a Label or something. Check out how this Ajax RSS parser is loading the RSS items in the source which can be downloaded here (Open Source - LGPL)

(Disclaimer; I work with Ra-Ajax...)

Not a solution worked for me, this is really unbearable, there's a file libpods.a(which was red coloured) I removed it and everything working fine! Cheers to me ;)

The OP states that each plot element overwrites the previous one rather than being combined into a single plot. This can happen even with one of the many suggestions made by other answers. If you select several lines and run them together, say:

plt.plot(<X>, <Y>)
plt.plot(<X>, <Z>)

the plot elements will typically be rendered together, one layer on top of the other. But if you execute the code line-by-line, each plot will overwrite the previous one.

This perhaps is what happened to the OP. It just happened to me: I had set up a new key binding to execute code by a single key press (on spyder), but my key binding was executing only the current line. The solution was to select lines by whole blocks or to run the whole file.

Step1: on click of the radio button it calls function populate data, with event (an object that has event details such as name of the element, value etc..);

Step2: I extracted the value through event.target.value and then simple switch will give me freedom to add custom text.

According to the documentation, in Sublime 2, the data directory should be on these locations:

• Windows: %APPDATA%\Sublime Text 2
• OS X: ~/Library/Application Support/Sublime Text 2
• Linux: ~/.config/sublime-text-2

This information is available here: http://docs.sublimetext.info/en/sublime-text-2/basic_concepts.html#the-data-directory

For Sublime 3, the locations are the following:

• Windows: %APPDATA%\Sublime Text 3
• OS X: ~/Library/Application Support/Sublime Text 3
• Linux: ~/.config/sublime-text-3

This information is available here:http://docs.sublimetext.info/en/sublime-text-3/basic_concepts.html#the-data-directory

If I understand correctly, you want to know how to convert bytes encoded as a hex string to its form as an ASCII text, like "537461636B" would be converted to "Stack", in such case then the following code should solve your problem.

Have not run any benchmarks but I assume it is not the peak of efficiency.

static char ByteToAscii(const char *input) {
  char singleChar, out;
  memcpy(&singleChar, input, 2);
  sprintf(&out, "%c", (int)strtol(&singleChar, NULL, 16));
  return out;
}

int HexStringToAscii(const char *input, unsigned int length,
                            char **output) {
  int mIndex, sIndex = 0;
  char buffer[length];
  for (mIndex = 0; mIndex < length; mIndex++) {
    sIndex = mIndex * 2;
    char b = ByteToAscii(&input[sIndex]);
    memcpy(&buffer[mIndex], &b, 1);
  }
  *output = strdup(buffer);
  return 0;
}

1. You can use a struct to read write into a file. You do not need to cast it as a `char*. Struct size will also be preserved. (This point is not closest to the topic but guess it: behaving on hard memory is often similar to RAM one.)

2. To move (to & from) a single string field you must use strncpy and a transient string buffer '\0' terminating. Somewhere you must remember the length of the record string field.

3. To move other fields you can use the dot notation, ex.: NodeB->one=intvar; floatvar2=(NodeA->insidebisnode_subvar).myfl;

   struct mynode {
       int one;
       int two;
       char txt3[3];
       struct{char txt2[6];}txt2fi;
       struct insidenode{
           char txt[8];
           long int myl;
           void * mypointer;
           size_t myst;
           long long myll;
            } insidenode_subvar;
       struct insidebisnode{
           float myfl;
            } insidebisnode_subvar;
   } mynode_subvar;
   
   typedef struct mynode* Node;
   
   ...(main)
   Node NodeA=malloc...
   Node NodeB=malloc...
   

4. You can embed each string into a structs that fit it, to evade point-2 and behave like Cobol: NodeB->txt2fi=NodeA->txt2fi ...but you will still need of a transient string plus one strncpy as mentioned at point-2 for scanf, printf otherwise an operator longer input (shorter), would have not be truncated (by spaces padded).

5. (NodeB->insidenode_subvar).mypointer=(NodeA->insidenode_subvar).mypointer will create a pointer alias.
6. NodeB.txt3=NodeA.txt3 causes the compiler to reject: error: incompatible types when assigning to type ‘char[3]’ from type ‘char *’

7. point-4 works only because NodeB->txt2fi & NodeA->txt2fi belong to the same typedef !!

   A correct and simple answer to this topic I found at In C, why can't I assign a string to a char array after it's declared? "Arrays (also of chars) are second-class citizens in C"!!!

Just hold cursor over member you interested in, and see tooltip - it will show memeber's type:

The precise meaning of these terms is going to depend a lot on what language/system/universe you are talking about.

In HTML/XML, an attribute is the part of a tag with an equals sign and a value, and property doesn't mean anything, for example.

So we need more information about what domain you're discussing.

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='bodb' AND TABLE_NAME='abc';

works for getting all column names

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

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

CREATE EXTENSION dblink;

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

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

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

CREATE EXTENSION dblink SCHEMA extensions;

See:

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

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

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

The magic variables %n contains the arguments used to invoke the file: %0 is the path to the bat-file itself, %1 is the first argument after, %2 is the second and so on.

Since the arguments are often file paths, there is some additional syntax to extract parts of the path. ~d is drive, ~p is the path (without drive), ~n is the file name. They can be combined so ~dp is drive+path.

%~dp0 is therefore pretty useful in a bat: it is the folder in which the executing bat file resides.

You can also get other kinds of meta info about the file: ~t is the timestamp, ~z is the size.

Look here for a reference for all command line commands. The tilde-magic codes are described under for.

According to this perlmonk's thread:

$string =~ s/^\s+|\s+$//g;

genrsa has been replaced by genpkey & when run manually in a terminal it will prompt for a password:

openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096

However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell script:

get_passwd() {
    local passwd=
    echo -ne "Enter passwd for private key: ? "; read -s passwd
    openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}

Don't know about git, but in Mercurial I'd just pipe the output of hg log to some sed/perl/whatever script to search for whatever it is you're looking for. You can customize the output of hg log using a template or a style to make it easier to search on, if you wish.

This will include all named branches in the repo. Mercurial does not have something like dangling blobs afaik.

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

I would recommend reading a book on C++ before you go any further, as it would be helpful to get a firmer footing. Accelerated C++ by Koenig and Moo is excellent.

To get the executable path use GetModuleFileName:

TCHAR buffer[MAX_PATH] = { 0 };
GetModuleFileName( NULL, buffer, MAX_PATH );

Here's a C++ function that gets the directory without the file name:

#include <windows.h>
#include <string>
#include <iostream>

wstring ExePath() {
    TCHAR buffer[MAX_PATH] = { 0 };
    GetModuleFileName( NULL, buffer, MAX_PATH );
    std::wstring::size_type pos = std::wstring(buffer).find_last_of(L"\\/");
    return std::wstring(buffer).substr(0, pos);
}

int main() {
    std::cout << "my directory is " << ExePath() << "\n";
}

Have you considered simply using System.Drawing namespace? For example:

System.Drawing.Color color = System.Drawing.Color.FromArgb(red, green, blue);
float hue = color.GetHue();
float saturation = color.GetSaturation();
float lightness = color.GetBrightness();

Note that it's not exactly what you've asked for (see differences between HSL and HSV and the Color class does not have a conversion back from HSL/HSV but the latter is reasonably easy to add.

The right way is to execute npm update. It's a really powerful command, it updates the missing packages and also checks if a newer version of package already installed can be used.

Read Intro to NPM to understand what you can do with npm.

I found this post more relevant in this scenario:

WITH upsert AS (
     UPDATE spider_count SET tally=tally+1 
     WHERE date='today' AND spider='Googlebot' 
     RETURNING *
)
INSERT INTO spider_count (spider, tally) 
SELECT 'Googlebot', 1 
WHERE NOT EXISTS (SELECT * FROM upsert)

You are triggering the event before the event is even bound.

Just move the triggering of the event to after attaching the event.

$(document).ready(function() {
  $("#checkbox_div input:radio").click(function() {

    alert("clicked");

   });

  $("input:radio:first").prop("checked", true).trigger("click");

});

Unfortunately, you can only turn on all invisible (whitespace) characters at the same time. I suggest you file an enhancement request but I doubt they will pick it up.

The text component in Eclipse is very complicated as it is and they are not keen on making them even worse.

[UPDATE] This has been fixed in Eclipse 3.7: Go to Window > Preferences > General > Editors > Text Editors

Clean your maven cache and rerun:

mvn dependency:purge-local-repository

This is just my personal opinion and folks from web API team can probably articulate it better but here is my 2c.

First of all, I think it is not a question of one over another. You can use them both depending on what you want to do in your action method but in order to understand the real power of IHttpActionResult, you will probably need to step outside those convenient helper methods of ApiController such as Ok, NotFound, etc.

Basically, I think a class implementing IHttpActionResult as a factory of HttpResponseMessage. With that mind set, it now becomes an object that need to be returned and a factory that produces it. In general programming sense, you can create the object yourself in certain cases and in certain cases, you need a factory to do that. Same here.

If you want to return a response which needs to be constructed through a complex logic, say lots of response headers, etc, you can abstract all those logic into an action result class implementing IHttpActionResult and use it in multiple action methods to return response.

Another advantage of using IHttpActionResult as return type is that it makes ASP.NET Web API action method similar to MVC. You can return any action result without getting caught in media formatters.

Of course, as noted by Darrel, you can chain action results and create a powerful micro-pipeline similar to message handlers themselves in the API pipeline. This you will need depending on the complexity of your action method.

Long story short - it is not IHttpActionResult versus HttpResponseMessage. Basically, it is how you want to create the response. Do it yourself or through a factory.

Easiest solution:

class OuterClass:
    outer_var = 1
    class InnerClass:
        def __init__(self):
            self.inner_var = OuterClass.outer_var

It requires you to be explicit, but doesn't take much effort.

This is good for shallow cloning. The object spread is a standard part of ECMAScript 2018.

For deep cloning you'll need a different solution.

const clone = {...original} to shallow clone

const newobj = {...original, prop: newOne} to immutably add another prop to the original and store as a new object.

Another approach to this would put a span element with a display:block style inside the p element each time you need the content to break. It would only be useful when your p content is static.

<p>this is a not-dynamic text and I want to put<span style="display:block">the following words in the next line</span>and these other words in a third one</p>

It would output:

This is a not-dynamic text and I want to put

the following words in the next line

and these others in a third one

This allows you to change your text line-breaks in different viewports without JS.

In DBeaver (or other editors) the script file you're working can prompt to save as UTF8 and that will change the char:

For me, it wasn't just getting the javadoc window to open, but also getting the complete javadoc to present. You may still get a sparse javadoc that is based solely on the method signature if you are importing libraries from a Maven repository and do not tell Idea to include the javadocs in the download. Be sure to tick the "JavaDocs" option in the "Download Library From Maven Repository" dialog, which can be found under Project Structure -> Projtect Settings -> Libraries.

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

The h1:first-child selector means

Select the first child of its parent
if and only if it's an h1 element.

The :first-child of the container here is the ul, and as such cannot satisfy h1:first-child.

There is CSS3's :first-of-type for your case:

.detail_container h1:first-of-type
{
    color: blue;
} 

But with browser compatibility woes and whatnot, you're better off giving the first h1 a class, then targeting that class:

.detail_container h1.first
{
    color: blue;
}

I used this code to produce your desired output. Is this what you were after?

reflect.DeepEqual is often incorrectly used to compare two like structs, as in your question.

cmp.Equal is a better tool for comparing structs.

To see why reflection is ill-advised, let's look at the documentation:

Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal.

....

numbers, bools, strings, and channels - are deeply equal if they are equal using Go's == operator.

If we compare two time.Time values of the same UTC time, t1 == t2 will be false if their metadata timezone is different.

go-cmp looks for the Equal() method and uses that to correctly compare times.

Example:

m1 := map[string]int{
    "a": 1,
    "b": 2,
}
m2 := map[string]int{
    "a": 1,
    "b": 2,
}
fmt.Println(cmp.Equal(m1, m2)) // will result in true

None of the answers here worked for me unfortunately.

I ended up using Custom Model Binding and used a third-party Sanitizer.

See my self-answered question here.

I realize you're looking for a "deep" copy of an array, but if you just have a single level array you can use this:

Copying a native JS Array is easy. Use the Array.slice() method which creates a copy of part/all of the array.

var foo = ['a','b','c','d','e'];
var bar = foo.slice();

now foo and bar are 5 member arrays of 'a','b','c','d','e'

of course bar is a copy, not a reference... so if you did this next...

bar.push('f');
alert('foo:' + foo.join(', '));
alert('bar:' + bar.join(', '));

you would now get:

foo:a, b, c, d, e
bar:a, b, c, d, e, f

Use Node.js's built-in copy function

It provides both async and sync version:

const fs = require('fs');

// File "destination.txt" will be created or overwritten by default.
fs.copyFile('source.txt', 'destination.txt', (err) => {
  if (err) 
      throw err;
  console.log('source.txt was copied to destination.txt');
});

fs.copyFileSync(src, dest[, mode])

I have found that from version 1.8.4 on, the libraries can be found in ~/Arduino/Libraries. Hope this helps anyone else.

You should grab a copy of Erica Sadun's mdhelper command line utility (OS X binary & source). It supports listing and extracting the contents of iPhone/iPod Touch backups, including address book & SMS databases, and other application metadata and settings.

I think these could be helpful for you .

Using a SELECT statement with a simple CASE expression

Within a SELECT statement, a simple CASE expression allows for only an equality check; no other comparisons are made. The following example uses the CASE expression to change the display of product line categories to make them more understandable.

USE AdventureWorks2012;
GO
SELECT   ProductNumber, Category =
      CASE ProductLine
         WHEN 'R' THEN 'Road'
         WHEN 'M' THEN 'Mountain'
         WHEN 'T' THEN 'Touring'
         WHEN 'S' THEN 'Other sale items'
         ELSE 'Not for sale'
      END,
   Name
FROM Production.Product
ORDER BY ProductNumber;
GO

Using a SELECT statement with a searched CASE expression

Within a SELECT statement, the searched CASE expression allows for values to be replaced in the result set based on comparison values. The following example displays the list price as a text comment based on the price range for a product.

USE AdventureWorks2012;
GO
SELECT   ProductNumber, Name, "Price Range" = 
      CASE 
         WHEN ListPrice =  0 THEN 'Mfg item - not for resale'
         WHEN ListPrice < 50 THEN 'Under $50'
         WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
         WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
         ELSE 'Over $1000'
      END
FROM Production.Product
ORDER BY ProductNumber ;
GO

Using CASE in an ORDER BY clause

The following examples uses the CASE expression in an ORDER BY clause to determine the sort order of the rows based on a given column value. In the first example, the value in the SalariedFlag column of the HumanResources.Employee table is evaluated. Employees that have the SalariedFlag set to 1 are returned in order by the BusinessEntityID in descending order. Employees that have the SalariedFlag set to 0 are returned in order by the BusinessEntityID in ascending order. In the second example, the result set is ordered by the column TerritoryName when the column CountryRegionName is equal to 'United States' and by CountryRegionName for all other rows.

SELECT BusinessEntityID, SalariedFlag
FROM HumanResources.Employee
ORDER BY CASE SalariedFlag WHEN 1 THEN BusinessEntityID END DESC
        ,CASE WHEN SalariedFlag = 0 THEN BusinessEntityID END;
GO


SELECT BusinessEntityID, LastName, TerritoryName, CountryRegionName
FROM Sales.vSalesPerson
WHERE TerritoryName IS NOT NULL
ORDER BY CASE CountryRegionName WHEN 'United States' THEN TerritoryName
         ELSE CountryRegionName END;

Using CASE in an UPDATE statement

The following example uses the CASE expression in an UPDATE statement to determine the value that is set for the column VacationHours for employees with SalariedFlag set to 0. When subtracting 10 hours from VacationHours results in a negative value, VacationHours is increased by 40 hours; otherwise, VacationHours is increased by 20 hours. The OUTPUT clause is used to display the before and after vacation values.

USE AdventureWorks2012;
GO
UPDATE HumanResources.Employee
SET VacationHours = 
    ( CASE
         WHEN ((VacationHours - 10.00) < 0) THEN VacationHours + 40
         ELSE (VacationHours + 20.00)
       END
    )
OUTPUT Deleted.BusinessEntityID, Deleted.VacationHours AS BeforeValue, 
       Inserted.VacationHours AS AfterValue
WHERE SalariedFlag = 0; 

Using CASE in a HAVING clause

The following example uses the CASE expression in a HAVING clause to restrict the rows returned by the SELECT statement. The statement returns the the maximum hourly rate for each job title in the HumanResources.Employee table. The HAVING clause restricts the titles to those that are held by men with a maximum pay rate greater than 40 dollars or women with a maximum pay rate greater than 42 dollars.

USE AdventureWorks2012;
GO
SELECT JobTitle, MAX(ph1.Rate)AS MaximumRate
FROM HumanResources.Employee AS e
JOIN HumanResources.EmployeePayHistory AS ph1 ON e.BusinessEntityID = ph1.BusinessEntityID
GROUP BY JobTitle
HAVING (MAX(CASE WHEN Gender = 'M' 
        THEN ph1.Rate 
        ELSE NULL END) > 40.00
     OR MAX(CASE WHEN Gender  = 'F' 
        THEN ph1.Rate  
        ELSE NULL END) > 42.00)
ORDER BY MaximumRate DESC;

Its usually better to whitelist characters you allow, rather than to blacklist characters you don't allow. both from a security standpoint, and from an ease of implementation standpoint.

If you do go down the blacklist route, here is an example, but be warned, the syntax is not simple.

http://groups.google.com/group/regex/browse_thread/thread/0795c1b958561a07

If you want to whitelist all the accent characters, perhaps using unicode ranges would help? Check out this link.

For some purposes, HtmlUtils:

import org.springframework.web.util.HtmlUtils;
[...]
HtmlUtils.htmlEscapeDecimal("&"); //gives &
HtmlUtils.htmlEscape("&"); //gives &

Use setExtendedState(int state), where state would be JFrame.MAXIMIZED_BOTH.

Wrap the "set" statement to mean "set if not set" and put it naked above the while loop.

You are correct, the language does not provide what you're looking for in exactly that syntax, but that's because there are programming paradigms like the one I just suggested so you don't need the syntax you are proposing.

1. mvn install

You can write code below in command line or if you're using eclipse builtin maven right click on project -> Run As -> run configurations... -> in left panel right click on Maven Build -> new configuration -> write the code in Goals & in base directory :${project_loc:NameOfYourProject} -> Run

mvn install:install-file
   -Dfile=<path-to-file>
   -DgroupId=<group-id>
   -DartifactId=<artifact-id>
   -Dversion=<version>
   -Dpackaging=<packaging>
   -DgeneratePom=true

Where each refers to:

< path-to-file >: the path to the file to load e.g -> c:\kaptcha-2.3.jar

< group-id >: the group that the file should be registered under e.g -> com.google.code

< artifact-id >: the artifact name for the file e.g -> kaptcha

< version >: the version of the file e.g -> 2.3

< packaging >: the packaging of the file e.g. -> jar

2.After installed, just declares jar in pom.xml.

 <dependency>
      <groupId>com.google.code</groupId>
      <artifactId>kaptcha</artifactId>
      <version>2.3</version>
 </dependency>

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

calling a function is simple ..

 myFunction();

so your code will be something like..

 $(function(){
     $('#elementID').click(function(){
         myFuntion();  //this will call your function
    });
 });

  $(function(){
     $('#elementID').click( myFuntion );

 });

or with some condition

if(something){
   myFunction();  //this will call your function
}

html, body {
    height: 100%;
    width: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    padding-top: 50px;
    display: table-cell;
}

div {
    margin: auto;
}

This will center align objects and then also center align the items within them to center align multiple objects with different widths.

Example picture

I am showing with an example of adding random color. You can write this way

var r = Math.floor(Math.random() * 255);
var g = Math.floor(Math.random() * 255);
var b = Math.floor(Math.random() * 255);
var col = "rgb(" + r + "," + g + "," + b + ")";
parent.childNodes[1].style.color = col;

The property is expected as a string

Simplest way to solve:

view()->share('title', 'My Title Here');

Or using view Facade:

use View;

...

View::share('title', 'My Title Here');

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.

When you want to edit something in Angular you need to insert an ngModel in your html

try this in your sample:

    <input type="text" name="abc" class="color" ng-model="myStyle.color">

You don't need to watch the change at all!

ChangeDetectorRef.detectChanges() is usually the most focused way of doing this. ApplicationRef.tick() is usually too much of a sledgehammer approach.

To use ChangeDetectorRef.detectChanges(), you'll need this at the top of your component:

import {  ChangeDetectorRef } from '@angular/core';

... then, usually you alias that when you inject it in your constructor like this:

constructor( private cdr: ChangeDetectorRef ) { ... }

Then, in the appropriate place, you call it like this:

this.cdr.detectChanges();

Where you call ChangeDetectorRef.detectChanges() can be highly significant. You need to completely understand the life cycle and exactly how your application is functioning and rendering its components. There's no substitute here for completely doing your homework and making sure you understand the Angular lifecycle inside out. Then, once you understand that, you can use ChangeDetectorRef.detectChanges() appropriately (sometimes it's very easy to understand where you should use it, other times it can be very complex).

Python has two kinds of sorts: a sort method (or "member function") and a sort function. The sort method operates on the contents of the object named -- think of it as an action that the object is taking to re-order itself. The sort function is an operation over the data represented by an object and returns a new object with the same contents in a sorted order.

Given a list of integers named l the list itself will be reordered if we call l.sort():

>>> l = [1, 5, 2341, 467, 213, 123]
>>> l.sort()
>>> l
[1, 5, 123, 213, 467, 2341]

This method has no return value. But what if we try to assign the result of l.sort()?

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = l.sort()
>>> print(r)
None

r now equals actually nothing. This is one of those weird, somewhat annoying details that a programmer is likely to forget about after a period of absence from Python (which is why I am writing this, so I don't forget again).

The function sorted(), on the other hand, will not do anything to the contents of l, but will return a new, sorted list with the same contents as l:

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = sorted(l)
>>> l
[1, 5, 2341, 467, 213, 123]
>>> r
[1, 5, 123, 213, 467, 2341]

Be aware that the returned value is not a deep copy, so be cautious about side-effecty operations over elements contained within the list as usual:

>>> spam = [8, 2, 4, 7]
>>> eggs = [3, 1, 4, 5]
>>> l = [spam, eggs]
>>> r = sorted(l)
>>> l
[[8, 2, 4, 7], [3, 1, 4, 5]]
>>> r
[[3, 1, 4, 5], [8, 2, 4, 7]]
>>> spam.sort()
>>> eggs.sort()
>>> l
[[2, 4, 7, 8], [1, 3, 4, 5]]
>>> r
[[1, 3, 4, 5], [2, 4, 7, 8]]

Most important

Keep in mind that relative URLs are resolved from the URL of your stylesheet.

So it will work if folder images is inside the stylesheets folder.

From you description you would need to change it to either

url("../images/plaid.jpg")

or

url("/images/plaid.jpg") 

Additional 1

Also you cannot have no selector..

CSS is applied through selectors..

Additional 2

You should use either the shorthand background to pass multiple values like this

background: url("../images/plaid.jpg") no-repeat;

or the verbose syntax of specifying each property on its own

background-image: url("../images/plaid.jpg");
background-repeat:no-repeat;

PowerShell one-liner to create a file in C:\Temp to fill disk C: leaving only 10 MB:

[io.file]::Create("C:\temp\bigblob.txt").SetLength((gwmi Win32_LogicalDisk -Filter "DeviceID='C:'").FreeSpace - 10MB).Close

Honestly this is bad advice from npm. An installation can run arbitrary scripts and running it with sudo can be extremely dangerous! You could do sudo npm install -g less to install it globally, but instead I would recommend updating your npm settings:

#~/.npmrc
prefix=~/.npm_modules

Then you can update your path:

#~/.bashrc or ~/.zshrc, etc.
export PATH=$PATH:$HOME/.npm_modules/bin

Then you don't require root permissions to perform the installation and you can still use the binary.

This would only apply to your user, however. If you want the entire system to be able to use the module you would have to tell everyone to add your path. More complicated and robust solutions would include adding a folder with node modules / binaries that a group could install to and adding that to everyone's path.

In case you using lookup to set default read from environment you have also set the second parameter of default to true:

- set_facts:
    ansible_ssh_user: "{{ lookup('env', 'SSH_USER') | default('foo', true) }}"

You can also concatenate multiple default definitions:

- set_facts:
    ansible_ssh_user: "{{ some_var.split('-')[1] | default(lookup('env','USER'), true) | default('foo') }}"

You should set your RecyclerView LayoutManager to Gridlayout mode. Just change your code when you want to set your RecyclerView LayoutManager:

recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), numberOfColumns));

This code creates a nice vertical scrollbar for me in Firefox and Chrome:

#answerform {
  position: absolute;
  border: 5px solid gray;
  padding: 5px;
  background: white;
  width: 300px;
  height: 400px;
  overflow-y: scroll;
}

<div id='answerform'>
  badger<br><br>badger<br><br>badger<br><br>badger<br><br>badger<br><br> mushroom
  <br><br>mushroom<br><br> a badger<br><br>badger<br><br>badger<br><br>badger<br><br>badger<br><br>
</div>

Here is a JS fiddle demo proving the above works.

Actually you can take advantage of the built-in Location service, which owns a "Back" API.

Here (in TypeScript):

import {Component} from '@angular/core';
import {Location} from '@angular/common';

@Component({
  // component's declarations here
})
class SomeComponent {

  constructor(private _location: Location) 
  {}

  backClicked() {
    this._location.back();
  }
}

Edit: As mentioned by @charith.arumapperuma Location should be imported from @angular/common so the import {Location} from '@angular/common'; line is important.

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

Here are the steps to pull a specific or any branch,

1.clone the master(you need to provide username and password)

       git clone <url>

2. the above command will clone the repository and you will be master branch now

       git checkout <branch which is present in the remote repository(origin)>

3. The above command will checkout to the branch you want to pull and will be set to automatically track that branch

4.If for some reason it does not work like that, after checking out to that branch in your local system, just run the below command

       git pull origin <branch>

For anyone else arriving here from Google search on how to do a string replacement on all columns (for example, if one has multiple columns like the OP's 'range' column): Pandas has a built in replace method available on a dataframe object.

df.replace(',', '-', regex=True)

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

your table:

q1 | q2 | q3 | q4 | q5

you can also do

ALTER TABLE yourtable ADD q6 VARCHAR( 255 ) after q5

>>> a = 147.234
>>> a % 1
0.23400000000000887
>>> a // 1
147.0
>>>

If you want the integer part as an integer and not a float, use int(a//1) instead. To obtain the tuple in a single passage: (int(a//1), a%1)

EDIT: Remember that the decimal part of a float number is approximate, so if you want to represent it as a human would do, you need to use the decimal library

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

type NumberArray = Array<{id: number, text: string}>;

const arr: NumberArray = [
    {id: 0, text: 'Number 0'},
    {id: 1, text: 'Number 1'},
    {id: 2, text: 'Number 2'},
    {id: 3, text: 'Number 3 '},
    {id: 4, text: 'Number 4 '},
    {id: 5, text: 'Number 5 '},
];

There are two separate things here:

1. object lifetime
2. storage duration

For example:

{
    vector<MyObject> v;
    // do some stuff, push some objects onto v
    v.clear(); // 1
    // maybe do some more stuff
} // 2

At 1, you clear v: this destroys all the objects it was storing. Each gets its destructor called, if your wrote one, and anything owned by that MyObject is now released. However, vector v has the right to keep the raw storage around in case you want it later.

If you decide to push some more things into it between 1 and 2, this saves time as it can reuse the old memory.

At 2, the vector v goes out of scope: any objects you pushed into it since 1 will be destroyed (as if you'd explicitly called clear again), but now the underlying storage is also released (v won't be around to reuse it any more).

If I change the example so v becomes a pointer to a dynamically-allocated vector, you need to explicitly delete it, as the pointer going out of scope at 2 doesn't do that for you. It's better to use something like std::unique_ptr in that case, but if you don't and v is leaked, the storage it allocated will be leaked as well. As above, you need to make sure v is deleted, and calling clear isn't sufficient.

A single-quoted string does not have variables within it interpreted. A double-quoted string does.

Also, a double-quoted string can contain apostrophes without backslashes, while a single-quoted string can contain unescaped quotation marks.

The single-quoted strings are faster at runtime because they do not need to be parsed.

Use border-collapse:seperate; and border-spacing:0; but only use border-right and border-bottom for the tds, with border-top applied to th and border-left applied to only tr td:nth-child(1).

You can then apply border radius to the corner tds (using nth-child to find them)

Try this . Works for subplots too .

axes = plt.gca()
axes.set_xlim([xmin,xmax])
axes.set_ylim([ymin,ymax])

       name='t1'
       id='t1'
       maxlength=10

This is the text box, it has a fixed length of 10 characters, and if you can try but this text box does not contain maximum length 10 character

Combining Günter Zöchbauer's answer with good-old vanilla-JS, here is a directive with two lines of logic that supports (123) 456-7890 format.

Reactive Forms: Plunk

import { Directive, Output, EventEmitter } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[formControlName][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  @Output() rawChange:EventEmitter<string> = new EventEmitter<string>();

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        var y = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(y);
        this.rawChange.emit(rawValue); 
  }
}

Template-driven Forms: Plunk

import { Directive } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[ngModel][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        value = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(value);       
  }
}

After reading the documentation: http://momentjs.com/docs/#/displaying/difference/, you have to consider the diff function like a minus operator.

                   // today < future (31/01/2014)
today.diff(future) // today - future < 0
future.diff(today) // future - today > 0

Therefore, you have to reverse your condition.

If you want to check that all is fine, you can add an extra parameter to the function:

moment().diff(SpecialTo, 'days') // -8 (days)

As RichieHindle pointed out the shortcut for column (block) selection is Alt+Shift+A. The problem I ran into is that the Android SDK on Eclipse uses 3 shortcuts that all start with Alt+Shift+A, so if you type that, you'll be given a choice of continuing with D, S, or R.

To solve this I redefined the column selection as Alt+Shift+A,A (Alt, Shift, A pressed together and then followed by a subsequent A). To do this go to Windows > Preferences then type keys or navigate to General > Keys. Under the Keys enter the filter text of block selection to quickly find the shortcut listing for toggle block selection. Here you can adjust the shortcut for column selection as you wish.

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

You can use the LIKE operator to compare the content of a T-SQL string, e.g.

SELECT * FROM [table] WHERE [field] LIKE '%stringtosearchfor%'.

The percent character '%' is a wild card- in this case it says return any records where [field] at least contains the value "stringtosearchfor".

Found a possible workaround that I don't believe was mentioned.

Here is a good description of the problem: http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api

Basically as long as you use forms/url-encoded/plain text content types you are fine.

$.ajax({
    type: "POST",
    headers: {
        'Accept': 'application/json',
        'Content-Type': 'text/plain'
    },
    dataType: "json",
    url: "http://localhost/endpoint",
    data: JSON.stringify({'DataToPost': 123}),
    success: function (data) {
        alert(JSON.stringify(data));
    }
});     

I use it with ASP.NET WebAPI2. So on the other end:

public static void RegisterWebApi(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    config.Formatters.Clear();
    config.Formatters.Add(new JsonMediaTypeFormatter());

    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/plain"));
}

This way Json formatter gets used when parsing plain text content type.

And don't forget in Web.config:

<system.webServer>
<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Methods" value="GET, POST" />
  </customHeaders>
</httpProtocol>    

Hope this helps.

Note: this answer applies only to Angular components and directives, NOT services.

I had this same issue when ngOnInit (and other lifecycle hooks) were not firing for my components, and most searches led me here.

The issue is that I was using the arrow function syntax (=>) like this:

class MyComponent implements OnInit {
    // Bad: do not use arrow function
    public ngOnInit = () => {
        console.log("ngOnInit");
    }
}

Apparently that does not work in Angular 6. Using non-arrow function syntax fixes the issue:

class MyComponent implements OnInit {
    public ngOnInit() {
        console.log("ngOnInit");
    }
}

You can remove an entry from your map by explicitly assigning it to 'undefined'. As in your case:

myArray["lastname"] = undefined;

The featured (but small and simple) library you can use is JSDialog: js.plus/products/jsdialog

Here is a sample for creating a dialog with Yes and No buttons:

JSDialog.showConfirmDialog(
    "Save document before it will be closed?\nIf you press `No` all unsaved changes will be lost.",
    function(result) {
        // check result here
    },
    "warning",
    "yes|no|cancel"
);

JS Dialog demo screenshot

I did this by putting target="_blank" in the linkbutton

<asp:LinkButton ID="btn" runat="server" CausesValidation="false"  Text="Print" Visible="false" target="_blank"  />

then in the codebehind pageload just set the href attribute:

btn.Attributes("href") = String.Format(ResolveUrl("~/") + "test/TestForm.aspx?formId={0}", formId)

Update: In an effort to answer my own question, here is what I've been able to uncover so far. If anyone else out there has something, I'd still be interested to find out more.

From the Differences Between DTDs and Schema section of the Converting a DTD into a Schema article:

The critical difference between DTDs and XML Schema is that XML Schema utilize an XML-based syntax, whereas DTDs have a unique syntax held over from SGML DTDs. Although DTDs are often criticized because of this need to learn a new syntax, the syntax itself is quite terse. The opposite is true for XML Schema, which are verbose, but also make use of tags and XML so that authors of XML should find the syntax of XML Schema less intimidating.

The goal of DTDs was to retain a level of compatibility with SGML for applications that might want to convert SGML DTDs into XML DTDs. However, in keeping with one of the goals of XML, "terseness in XML markup is of minimal importance," there is no real concern with keeping the syntax brief.

[...]

So what are some of the other differences which might be especially important when we are converting a DTD? Let's take a look.

Typing

The most significant difference between DTDs and XML Schema is the capability to create and use datatypes in Schema in conjunction with element and attribute declarations. In fact, it's such an important difference that one half of the XML Schema Recommendation is devoted to datatyping and XML Schema. We cover datatypes in detail in Part III of this book, "XML Schema Datatypes."

[...]

Occurrence Constraints

Another area where DTDs and Schema differ significantly is with occurrence constraints. If you recall from our previous examples in Chapter 2, "Schema Structure" (or your own work with DTDs), there are three symbols that you can use to limit the number of occurrences of an element: *, + and ?.

[...]

Enumerations

So, let's say we had a element, and we wanted to be able to define a size attribute for the shirt, which allowed users to choose a size: small, medium, or large. Our DTD would look like this:

<!ELEMENT item (shirt)>
<!ELEMENT shirt (#PCDATA)>
<!ATTLIST shirt
    size_value (small | medium | large)>

[...]

But what if we wanted size to be an element? We can't do that with a DTD. DTDs do not provide for enumerations in an element's text content. However, because of datatypes with Schema, when we declared the enumeration in the preceding example, we actually created a simpleType called size_values which we can now use with an element:

<xs:element name="size" type="size_value">

[...]

The program will terminate when the execution flow reaches the end of the main function.

To terminate it before then, you can use the exit(int status) function, where status is a value returned to whatever started the program. 0 normally indicates a non-error state

The usual error is one tries to put Content-Type: {multipart/form-data} into the header of the post request. That will fail, it is best to let Postman do it for you. For example:

Suggestion To Load Via Postman

Fails If In Header

Works

If you are using Vim on Windows, you can get access to the clipboard (MS copy/paste) using:

"*dd -- cut a line (or 3dd to cut three lines)

"*yy -- copy a line (or 3yy to copy three lines)

"*p -- paste line(s) on line after the cursor

"*P -- paste line(s) on line before the cursor

The lets you paste between separate Vim windows or between Vim and PC applications (Notepad, Microsoft Word, etc.).

The answers with the text-transformation:uppercase styling will not send uppercased data to the server on submit - what you might expect. You can do something like this instead:

For your input HTML use onkeydown:

<input name="yourInput" onkeydown="upperCaseF(this)"/>

In your JavaScript:

function upperCaseF(a){
    setTimeout(function(){
        a.value = a.value.toUpperCase();
    }, 1);
}

With upperCaseF() function on every key press down, the value of the input is going to turn into its uppercase form.

I also added a 1ms delay so that the function code block triggers after the keydown event occured.

UPDATE

Per remommendation from Dinei, you can use oninput event instead of onkeydown and get rid of setTimeout.

For your input HTML use oninput:

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

The shortest form of safe $apply is:

$timeout(angular.noop)

function page_properties($objPortal) {    
    $objPage->set_page_title($myrow['title']);
}

looks like different names of variables $objPortal vs $objPage

According to updated Apple document (check my answer date):

"... When using the HTTP/2 provider API, maximum payload size is 4096 bytes. Using the legacy binary interface, maximum payload size is 2048 bytes. Apple Push Notification service (APNs) refuses any notification that exceeds the maximum size."

Yes, here's an example:

CREATE TABLE myTable ( col1 int, createdDate datetime DEFAULT(getdate()), updatedDate datetime DEFAULT(getdate()) )

You can INSERT into the table without indicating the createdDate and updatedDate columns:

INSERT INTO myTable (col1) VALUES (1)

Or use the keyword DEFAULT:

INSERT INTO myTable (col1, createdDate, updatedDate) VALUES (1, DEFAULT, DEFAULT)

Then create a trigger for updating the updatedDate column:

CREATE TRIGGER dbo.updateMyTable 
ON dbo.myTable
FOR UPDATE 
AS 
BEGIN 
    IF NOT UPDATE(updatedDate) 
        UPDATE dbo.myTable SET updatedDate=GETDATE() 
        WHERE col1 IN (SELECT col1 FROM inserted) 
END 
GO

Capturing lambdas cannot be converted to function pointers, as this answer pointed out.

However, it is often quite a pain to supply a function pointer to an API that only accepts one. The most often cited method to do so is to provide a function and call a static object with it.

static Callable callable;
static bool wrapper()
{
    return callable();
}

This is tedious. We take this idea further and automate the process of creating wrapper and make life much easier.

#include<type_traits>
#include<utility>

template<typename Callable>
union storage
{
    storage() {}
    std::decay_t<Callable> callable;
};

template<int, typename Callable, typename Ret, typename... Args>
auto fnptr_(Callable&& c, Ret (*)(Args...))
{
    static bool used = false;
    static storage<Callable> s;
    using type = decltype(s.callable);

    if(used)
        s.callable.~type();
    new (&s.callable) type(std::forward<Callable>(c));
    used = true;

    return [](Args... args) -> Ret {
        return Ret(s.callable(std::forward<Args>(args)...));
    };
}

template<typename Fn, int N = 0, typename Callable>
Fn* fnptr(Callable&& c)
{
    return fnptr_<N>(std::forward<Callable>(c), (Fn*)nullptr);
}

And use it as

void foo(void (*fn)())
{
    fn();   
}

int main()
{
    int i = 42;
    auto fn = fnptr<void()>([i]{std::cout << i;});
    foo(fn);  // compiles!
}

Live

This is essentially declaring an anonymous function at each occurrence of fnptr.

Note that invocations of fnptr overwrite the previously written callable given callables of the same type. We remedy this, to a certain degree, with the int parameter N.

std::function<void()> func1, func2;
auto fn1 = fnptr<void(), 1>(func1);
auto fn2 = fnptr<void(), 2>(func2);  // different function

\d means 'digit'. + means, '1 or more times'. So \d+ means one or more digit. It will match 12 and 1.

I came up with this simple and straight-forward (i hope so) code example which should explain itself!

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

/* function header definitions */
char* getString();                     //<- with malloc (good practice)
char * getStringNoMalloc();  //<- without malloc (fails! don't do this!)
void getStringCallByRef(char* reference); //<- callbyref (good practice)

/* the main */
int main(int argc, char*argv[]) {

    //######### calling with malloc
    char * a = getString();
    printf("MALLOC ### a = %s \n", a); 
    free(a);

    //######### calling without malloc
    char * b = getStringNoMalloc();
    printf("NO MALLOC ### b = %s \n", b); //this doesnt work, question to yourself: WHY?
    //HINT: the warning says that a local reference is returned. ??!
    //NO free here!

    //######### call-by-reference
    char c[100];
    getStringCallByRef(c);
    printf("CALLBYREF ### c = %s \n", c);

    return 0;
}

//WITH malloc
char* getString() {

    char * string;
    string = malloc(sizeof(char)*100);

    strcat(string, "bla");
    strcat(string, "/");
    strcat(string, "blub");

    printf("string : '%s'\n", string);

    return string;
}

//WITHOUT malloc (watch how it does not work this time)
char* getStringNoMalloc() {

     char string[100] = {};

     strcat(string, "bla");
     strcat(string, "/");
     strcat(string, "blub");
     //INSIDE this function "string" is OK
     printf("string : '%s'\n", string);

     return string; //but after returning.. it is NULL? :)
}

// ..and the call-by-reference way to do it (prefered)
void getStringCallByRef(char* reference) {

    strcat(reference, "bla");
    strcat(reference, "/");
    strcat(reference, "blub");
    //INSIDE this function "string" is OK
    printf("string : '%s'\n", reference);
    //OUTSIDE it is also OK because we hand over a reference defined in MAIN
    // and not defined in this scope (local), which is destroyed after the function finished
}

When compiling it, you get the [intended] warning:

me@box:~$ gcc -o example.o example.c 
example.c: In function ‘getStringNoMalloc’:
example.c:58:16: warning: function returns address of local variable [-Wreturn-local-addr]
         return string; //but after returning.. it is NULL? :)
            ^~~~~~

...basically what we are discussing here!

running my example yields this output:

me@box:~$ ./example.o 
string : 'bla/blub'
MALLOC ### a = bla/blub 
string : 'bla/blub'
NO MALLOC ### b = (null) 
string : 'bla/blub'
CALLBYREF ### c = bla/blub 

Theory:

This has been answered very nicely by User @phoxis. Basically think about it this way: Everything inbetween { and } is local scope, thus by the C-Standard is "undefined" outside. By using malloc you take memory from the HEAP (programm scope) and not from the STACK (function scope) - thus its 'visible' from outside. The second correct way to do it is call-by-reference. Here you define the var inside the parent-scope, thus it is using the STACK (because the parent scope is the main()).

Summary:

3 Ways to do it, One of them false. C is kind of to clumsy to just have a function return a dynamically sized String. Either you have to malloc and then free it, or you have to call-by-reference. Or use C++ ;)

use FileInputStream's readLine() method to read and parse the returned String to int using Integer.parseInt() method.

Update 2015-01-20:

As per https://pip.pypa.io/en/latest/installing.html the current way is:

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py

I think that should work for any version

Original Answer:

wget http://python-distribute.org/distribute_setup.py
python distribute_setup.py

The bottom is the top + the outerHeight, not the height, as it wouldn't include the margin or padding.

var $bot,
    top,
    bottom;
$bot = $('#bottom');
top = $bot.position().top;
bottom = top + $bot.outerHeight(true); //true is necessary to include the margins

None of the above solutions worked for me (dotnetcore 1.1, VS2017). Here's what fixed it:

1. Add NuGet Package Microsoft.TestPlatform.TestHost
2. Add NuGet Package Microsoft.NET.Test.Sdk

Those are in addition to these packages I installed prior:

• xunit (2.3.0-beta1-build3642)
• xunit.runner.visualstudio (2.3.0-beta1-build1309)

From a quick google search it seems that the problem is a file or url couldn't be found be the HTTPservice.

Here are the links where I found this information:

Yes, you can find that under

Tools - > Options - > Projects and Solutions - > Track Active Item in Solution Explorer

It's off by default (as you've noticed), but once it's on, Solution Explorer will expand folders and highlight the current document as you switch between files.

Just To mention, in CSS 3

:after

should be used like this

::after

From https://developer.mozilla.org/de/docs/Web/CSS/::after :

The ::after notation was introduced in CSS 3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :after introduced in CSS 2.

So it should be:

li { display: inline; list-style-type: none; }
li::after { content: ", "; }
li:last-child::before { content: "and "; }
li:last-child::after { content: "."; }

If you have installed mongodb community server via homebrew, then you can do:

brew services list

This will list the current services as below:

Name              Status  User          Plist
mongodb-community started thehaystacker /Users/thehaystacker/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist

redis             stopped

Then you can restart mongodb by first stopping and restart:

brew services stop mongodb
brew services start mongodb

:vsp or :sp - splits vim into two instance but you cannot use :shell in only one of them.

Why not display another tab of the terminal not another tab of vim. If you like the idea you can try it: Ctrl-shift-t. and move between them with Ctrl - pageup and Ctrl - pagedown

If you want just a few shell commands you can make any shell command in vim using !

For example :!./a.out.

VB 6 provides a Clipboard object that makes all of this extremely simple and convenient, but unfortunately that's not available from VBA.

If it were me, I'd go the API route. There's no reason to be scared of calling native APIs; the language provides you with the ability to do that for a reason.

However, a simpler alternative is to use the DataObject class, which is part of the Forms library. I would only recommend going this route if you are already using functionality from the Forms library in your app. Adding a reference to this library only to use the clipboard seems a bit silly.

For example, to place some text on the clipboard, you could use the following code:

Dim clipboard As MSForms.DataObject
Set clipboard = New MSForms.DataObject
clipboard.SetText "A string value"
clipboard.PutInClipboard

Or, to copy text from the clipboard into a string variable:

Dim clipboard As MSForms.DataObject
Dim strContents As String

Set clipboard = New MSForms.DataObject
clipboard.GetFromClipboard
strContents = clipboard.GetText

use this for target path for uploading

<?php
$file_name = $_FILES["csvFile"]["name"];
$target_path = $dir = plugin_dir_path( __FILE__ )."\\upload\\". $file_name;
echo $target_path;
move_uploaded_file($_FILES["csvFile"]["tmp_name"],$target_path. $file_name);
?>

Address already in use means that the port you are trying to allocate for your current execution is already occupied/allocated to some other process.

If you are a developer and if you are working on an application which require lots of testing, you might have an instance of your same application running in background (may be you forgot to stop it properly)

So if you encounter this error, just see which application/process is using the port.

In linux try using netstat -tulpn. This command will list down a process list with all running processes.

Check if an application is using your port. If that application or process is another important one then you might want to use another port which is not used by any process/application.

Anyway you can stop the process which uses your port and let your application take it.

If you are in linux environment try,

• Use netstat -tulpn to display the processes
• kill <pid> This will terminate the process

If you are using windows,

• Use netstat -a -o -n to check for the port usages
• Use taskkill /F /PID <pid> to kill that process

in an actual SQL query, you just add a newline

INSERT INTO table (text) VALUES ('hi this is some text
and this is a linefeed.
and another');

Of course there is an automated way called serialization and deserialization and you can define it with specific annotations (@JsonSerialize,@JsonDeserialize) as mentioned by pb2q as well.

You can use both java.util.Date and java.util.Calendar ... and probably JodaTime as well.

The @JsonFormat annotations not worked for me as I wanted (it has adjusted the timezone to different value) during deserialization (the serialization worked perfect):

@JsonFormat(locale = "hu", shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm", timezone = "CET")

@JsonFormat(locale = "hu", shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm", timezone = "Europe/Budapest")

You need to use custom serializer and custom deserializer instead of the @JsonFormat annotation if you want predicted result. I have found real good tutorial and solution here http://www.baeldung.com/jackson-serialize-dates

There are examples for Date fields but I needed for Calendar fields so here is my implementation:

The serializer class:

public class CustomCalendarSerializer extends JsonSerializer<Calendar> {

    public static final SimpleDateFormat FORMATTER = new SimpleDateFormat("yyyy-MM-dd HH:mm");
    public static final Locale LOCALE_HUNGARIAN = new Locale("hu", "HU");
    public static final TimeZone LOCAL_TIME_ZONE = TimeZone.getTimeZone("Europe/Budapest");

    @Override
    public void serialize(Calendar value, JsonGenerator gen, SerializerProvider arg2)
            throws IOException, JsonProcessingException {
        if (value == null) {
            gen.writeNull();
        } else {
            gen.writeString(FORMATTER.format(value.getTime()));
        }
    }
}

The deserializer class:

public class CustomCalendarDeserializer extends JsonDeserializer<Calendar> {

    @Override
    public Calendar deserialize(JsonParser jsonparser, DeserializationContext context)
            throws IOException, JsonProcessingException {
        String dateAsString = jsonparser.getText();
        try {
            Date date = CustomCalendarSerializer.FORMATTER.parse(dateAsString);
            Calendar calendar = Calendar.getInstance(
                CustomCalendarSerializer.LOCAL_TIME_ZONE, 
                CustomCalendarSerializer.LOCALE_HUNGARIAN
            );
            calendar.setTime(date);
            return calendar;
        } catch (ParseException e) {
            throw new RuntimeException(e);
        }
    }
}

and the usage of the above classes:

public class CalendarEntry {

    @JsonSerialize(using = CustomCalendarSerializer.class)
    @JsonDeserialize(using = CustomCalendarDeserializer.class)
    private Calendar calendar;

    // ... additional things ...
}

Using this implementation the execution of the serialization and deserialization process consecutively results the origin value.

Only using the @JsonFormat annotation the deserialization gives different result I think because of the library internal timezone default setup what you can not change with annotation parameters (that was my experience with Jackson library 2.5.3 and 2.6.3 version as well).

Swift3:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController("LoginViewController") as UIViewController
self.navigationController?.pushViewController(vc, animated: true)

Try this out. You just confused nib with storyboard representation.

<li>s don't have a value - only form inputs do. In fact, you're not supposed to even include the value attribute in the HTML for <li>s.

You can rely on .innerHTML instead:

getPaging(this.innerHTML)

Or maybe the id:

getPaging(this.id);

However, it's easier (and better practice) to add the click handlers from JavaScript code, and not include them in the HTML. Seeing as you're already using jQuery, this can easily be done by changing your HTML to:

<li class="clickMe">1</li>
<li class="clickMe">2</li>

And use the following JavaScript:

$(function () {
    $('.clickMe').click(function () {
        var str = $(this).text();
        $('#loading-content').load('dataSearch.php?' + str, hideLoader);
    });
});

This will add the same click handler to all your <li class="clickMe">s, without requiring you to duplicate your onclick="getPaging(this.value)" code for each of them.

I face the same issue. I am using docker version:17.09.0-ce.

I follow below steps:

1. Create Dockerfile and added commands for creating docker image
2. Go to directory where we have created Dockfile
3. execute below command $ sudo docker build -t ubuntu-test:latest .

It resolved issue and image created successsfully.

Note: build command depend on docker version as well as which build option we are using. :)

This can also occur if your stored procedure encounters a compile failure after opening a transaction (e.g. table not found, invalid column name).

I found i had to use 2 stored procedures a "worker" one and a wrapper one with try/catch both with logic similar to that outlined by Remus Rusanu. The worker catch is used to handle the "normal" failures and the wrapper catch to handle compile failure errors.

Errors Unaffected by a TRY…CATCH Construct

The following types of errors are not handled by a CATCH block when they occur at the same level of execution as the TRY…CATCH construct:

• Compile errors, such as syntax errors, that prevent a batch from running.
• Errors that occur during statement-level recompilation, such as object name resolution errors that occur after compilation because of deferred name resolution.

Hopefully this helps someone else save a few hours of debugging...

It's not valid XHTML to have to have nested forms. However, you can use multiple submit buttons and use a serverside script to run different codes depending on which button the users has clicked.

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

1. Enable External option in Unity ? Preferences ? Packages ? Repository
2. Switch to Hidden Meta Files in Editor ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Editor ? Project Settings ? Editor ? Asset Serialization Mode
4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.

More information about keeping Unity Project under source control you can find in this post.

I use the following implementation of round in asm for x86 architecture and MS VS specific C++:

__forceinline int Round(const double v)
{
    int r;
    __asm
    {
        FLD     v
        FISTP   r
        FWAIT
    };
    return r;
}

UPD: to return double value

__forceinline double dround(const double v)
{
    double r;
    __asm
    {
        FLD     v
        FRNDINT
        FSTP    r
        FWAIT
    };
    return r;
}

Output:

dround(0.1): 0.000000000000000
dround(-0.1): -0.000000000000000
dround(0.9): 1.000000000000000
dround(-0.9): -1.000000000000000
dround(1.1): 1.000000000000000
dround(-1.1): -1.000000000000000
dround(0.49999999999999994): 0.000000000000000
dround(-0.49999999999999994): -0.000000000000000
dround(0.5): 0.000000000000000
dround(-0.5): -0.000000000000000

Swift 3

Orientation rotation is more complicated if a view controller is embedded in UINavigationController or UITabBarController the navigation or tab bar controller takes precedence and makes the decisions on autorotation and supported orientations.

Use the following extensions on UINavigationController and UITabBarController so that view controllers that are embedded in one of these controllers get to make the decisions:

UINavigationController extension

extension UINavigationController {

override open var shouldAutorotate: Bool {
    get {
        if let visibleVC = visibleViewController {
            return visibleVC.shouldAutorotate
        }
        return super.shouldAutorotate
    }
}

override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    get {
        if let visibleVC = visibleViewController {
            return visibleVC.preferredInterfaceOrientationForPresentation
        }
        return super.preferredInterfaceOrientationForPresentation
    }
}

override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    get {
        if let visibleVC = visibleViewController {
            return visibleVC.supportedInterfaceOrientations
        }
        return super.supportedInterfaceOrientations
    }
 }}

UITabBarController extension

extension UITabBarController {

override open var shouldAutorotate: Bool {
    get {
        if let selectedVC = selectedViewController{
            return selectedVC.shouldAutorotate
        }
        return super.shouldAutorotate
    }
}

override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    get {
        if let selectedVC = selectedViewController{
            return selectedVC.preferredInterfaceOrientationForPresentation
        }
        return super.preferredInterfaceOrientationForPresentation
    }
}

override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    get {
        if let selectedVC = selectedViewController{
            return selectedVC.supportedInterfaceOrientations
        }
        return super.supportedInterfaceOrientations
    }
}}

Now you can override the supportedInterfaceOrientations, shouldAutoRotate and preferredInterfaceOrientationForPresentation in the view controller you want to lock down otherwise you can leave out the overrides in other view controllers that you want to inherit the default orientation behavior specified in your app's plist.

Lock to Specific Orientation

class YourViewController: UIViewController {
open override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    get {
        return .portrait
    }
}}

Disable Rotation

    class YourViewController: UIViewController {
open override var shouldAutorotate: Bool {
    get {
        return false
    }
}}

Change Preferred Interface Orientation For Presentation

class YourViewController: UIViewController {
open override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    get {
        return .portrait
    }
}}

I got few corrections to post of @MakeAppPie

First at all when you are creating delegate protocol it should conform to Class protocol. Like in example below.

protocol ProtocolDelegate: class {
    func myMethod(controller:ViewController, text:String)
}

Second, your delegate should be weak to avoid retain cycle.

class ViewController: UIViewController {
    weak var delegate: ProtocolDelegate?
}

Last, you're safe because your protocol is an optional value. That means its "nil" message will be not send to this property. It's similar to conditional statement with respondToselector in objC but here you have everything in one line:

if ([self.delegate respondsToSelector:@selector(myMethod:text:)]) {
    [self.delegate myMethod:self text:@"you Text"];
}

Above you have an obj-C example and below you have Swift example of how it looks.

delegate?.myMethod(self, text:"your Text")

For macOS/OS X, you can use the subprocess module and call 'cls' from the shell:

import subprocess as sp
sp.call('cls', shell=True)

To prevent '0' from showing on top of the window, replace the 2nd line with:

tmp = sp.call('cls', shell=True)

For Linux, you must replace cls command with clear

tmp = sp.call('clear', shell=True)

New in version 3.4.

import pathlib

print(pathlib.Path('yourPath.example').suffix) # '.example'

I'm surprised no one has mentioned pathlib yet, pathlib IS awesome!

If you need all the suffixes (eg if you have a .tar.gz), .suffixes will return a list of them!

It's a textual encoding of binary data where the resultant text has nothing but letters, numbers and the symbols "+", "/" and "=". It's a convenient way to store/transmit binary data over media that is specifically used for textual data.

But why Base-64? The two alternatives for converting binary data into text that immediately spring to mind are:

1. Decimal: store the decimal value of each byte as three numbers: 045 112 101 037 etc. where each byte is represented by 3 bytes. The data bloats three-fold.
2. Hexadecimal: store the bytes as hex pairs: AC 47 0D 1A etc. where each byte is represented by 2 bytes. The data bloats two-fold.

Base-64 maps 3 bytes (8 x 3 = 24 bits) in 4 characters that span 6-bits (6 x 4 = 24 bits). The result looks something like "TWFuIGlzIGRpc3Rpb...". Therefore the bloating is only a mere 4/3 = 1.3333333 times the original.

Floating point numbers are represented in scientific notation as a number of only seven significant digits multiplied by a larger number that represents the place of the decimal place. More information about it on Wikipedia:

http://en.wikipedia.org/wiki/Floating_point

This is essentially the same thing. Use whatever you find more convenient.

As a sidenote to this:

netsh http add urlacl url=http://vaidesg:8080/ user=everyone

This will only work on English versions of Windows. If you are using a localized version you have to replace "everyone" with something else, for example:

• "Iedereen" when using a Dutch version
• "Jeder" when using a German version
• "Mindenki" when using a Hungarian version

Otherwise you will get an error (Create SDDL failed, Error: 1332)

in your constructor you are creating another int array:

 public Date(){
  int[] data = {0,0,0};
  }

Try this:

 data = {0,0,0};

NOTE: By the way you do NOT need to initialize your array elements if it is declared as an instance variable. Instance variables automatically get their default values, which for an integer array, the default values are all zeroes.

If you had locally declared array though they you would need to initialize each element.

This simple solution worked for me: file-upload.component.html

<div>
  <input type="file" #fileInput placeholder="Upload file..." />
  <button type="button" (click)="upload()">Upload</button>
</div>

And then do the upload in the component directly with XMLHttpRequest.

import { Component, OnInit, ViewChild } from '@angular/core';

@Component({
  selector: 'app-file-upload',
  templateUrl: './file-upload.component.html',
  styleUrls: ['./file-upload.component.css']
})
export class FileUploadComponent implements OnInit {

  @ViewChild('fileInput') fileInput;

  constructor() { }

  ngOnInit() {
  }

  private upload() {
    const fileBrowser = this.fileInput.nativeElement;
    if (fileBrowser.files && fileBrowser.files[0]) {
      const formData = new FormData();
      formData.append('files', fileBrowser.files[0]);
      const xhr = new XMLHttpRequest();
      xhr.open('POST', '/api/Data/UploadFiles', true);
      xhr.onload = function () {
        if (this['status'] === 200) {
            const responseText = this['responseText'];
            const files = JSON.parse(responseText);
            //todo: emit event
        } else {
          //todo: error handling
        }
      };
      xhr.send(formData);
    }
  }

}

If you are using dotnet core, the parameter name must match the from field name. files in this case:

[HttpPost("[action]")]
public async Task<IList<FileDto>> UploadFiles(List<IFormFile> files)
{
  return await _binaryService.UploadFilesAsync(files);
}

This answer is a plagiate of http://blog.teamtreehouse.com/uploading-files-ajax

Edit: After uploading, you have to clear the file-upload so that the user can select a new file. And instead of using XMLHttpRequest, maybe it is better to use fetch:

private addFileInput() {
    const fileInputParentNative = this.fileInputParent.nativeElement;
    const oldFileInput = fileInputParentNative.querySelector('input');
    const newFileInput = document.createElement('input');
    newFileInput.type = 'file';
    newFileInput.multiple = true;
    newFileInput.name = 'fileInput';
    const uploadfiles = this.uploadFiles.bind(this);
    newFileInput.onchange = uploadfiles;
    oldFileInput.parentNode.replaceChild(newFileInput, oldFileInput);
  }

  private uploadFiles() {
    this.onUploadStarted.emit();
    const fileInputParentNative = this.fileInputParent.nativeElement;
    const fileInput = fileInputParentNative.querySelector('input');
    if (fileInput.files && fileInput.files.length > 0) {
      const formData = new FormData();
      for (let i = 0; i < fileInput.files.length; i++) {
        formData.append('files', fileInput.files[i]);
      }

      const onUploaded = this.onUploaded;
      const onError = this.onError;
      const addFileInput = this.addFileInput.bind(this);
      fetch('/api/Data/UploadFiles', {
        credentials: 'include',
        method: 'POST',
        body: formData,
      }).then((response: any) => {
        if (response.status !== 200) {
          const error = `An error occured. Status: ${response.status}`;
          throw new Error(error);
        }
        return response.json();
      }).then(files => {
        onUploaded.emit(files);
        addFileInput();
      }).catch((error) => {
        onError.emit(error);
      });
    }

If you are using Storyboard and your "add" viewController is in storyboard then set an identifier for your "add" viewcontroller in settings so you can do something like this:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"NameOfYourStoryBoard" 
                                                     bundle:nil];
AddTaskViewController *add = 
           [storyboard instantiateViewControllerWithIdentifier:@"viewControllerIdentifier"];

[self presentViewController:add 
                   animated:YES 
                 completion:nil];

if you do not have your "add" viewController in storyboard or a nib file and want to create the whole thing programmaticaly then appDocs says:

If you cannot define your views in a storyboard or a nib file, override the loadView method to manually instantiate a view hierarchy and assign it to the view property.

I just found this error., while using GETDATE() [i.e outer reference] in the group by clause in a select query.

When replaced it with date column from the respective table it cleared.

Any browser with Flash can support WebSocket using the web-socket-js shim/polyfill.

See caniuse for the current status of WebSockets support in desktop and mobile browsers.

See the test reports from the WS testsuite included in Autobahn WebSockets for feature/protocol conformance tests.

Server side

It depends on which language you use.

In Java/Java EE:

• Jetty 7.0 supports it (very easy to use) V 7.5 supports RFC6455 - Jetty 9.1 supports javax.websocket / JSR 356)
• GlassFish 3.0 (very low level and sometimes complex), Glassfish 3.1 has new refactored Websocket Support which is more developer friendly V 3.1.2 supports RFC6455
• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete. See Arun GUPTA's article WebSocket and Java EE 7 - Getting Ready for JSR 356 (TOTD #181) and QCon presentation (from 00:37:36 to 00:46:53) for more information on progress.

I just found some issues on FAB and I want to enhance another answer.

setRippleColor issue

So, the issue will come once you set the ripple color (FAB color on pressed) programmatically through setRippleColor. But, we still have an alternative way to set it, i.e. by calling:

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
ColorStateList rippleColor = ContextCompat.getColorStateList(context, R.color.fab_ripple_color);
fab.setBackgroundTintList(rippleColor);

Your project need to has this structure:

/res/color/fab_ripple_color.xml

And the code from fab_ripple_color.xml is:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:color="@color/fab_color_pressed" />
    <item android:state_focused="true" android:color="@color/fab_color_pressed" />
    <item android:color="@color/fab_color_normal"/>
</selector>

Finally, alter your FAB slightly:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_add"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    app:fabSize="normal"
    app:borderWidth="0dp"
    app:elevation="6dp"
    app:pressedTranslationZ="12dp"
    app:rippleColor="@android:color/transparent"/> <!-- set to transparent color -->

For API level 21 and higher, set margin right and bottom to 24dp:

...
android:layout_marginRight="24dp"
android:layout_marginBottom="24dp" />

FloatingActionButton design guides

As you can see on my FAB xml code above, I set:

        ...
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        app:elevation="6dp"
        app:pressedTranslationZ="12dp"
        ...

• By setting these attributes, you don't need to set layout_marginTop and layout_marginRight again (only on pre-Lollipop). Android will place it automatically on the right corned side of the screen, which the same as normal FAB in Android Lollipop.

      android:layout_alignParentBottom="true"
      android:layout_alignParentRight="true"
  

Or, you can use this in CoordinatorLayout:

        android:layout_gravity="end|bottom"

• You need to have 6dp elevation and 12dp pressedTranslationZ, according to this guide from Google.

Use the .Select() after grouping:

var agencyContracts = _agencyContractsRepository.AgencyContracts
    .GroupBy(ac => new
                   {
                       ac.AgencyContractID, // required by your view model. should be omited
                                            // in most cases because group by primary key
                                            // makes no sense.
                       ac.AgencyID,
                       ac.VendorID,
                       ac.RegionID
                   })
    .Select(ac => new AgencyContractViewModel
                   {
                       AgencyContractID = ac.Key.AgencyContractID,
                       AgencyId = ac.Key.AgencyID,
                       VendorId = ac.Key.VendorID,
                       RegionId = ac.Key.RegionID,
                       Amount = ac.Sum(acs => acs.Amount),
                       Fee = ac.Sum(acs => acs.Fee)
                   });

If you are looking to average column wise. Try this,

df.drop('Region', axis=1).apply(lambda x: x.mean())

# it drops the Region column
df.drop('Region', axis=1,inplace=True)

Also may be helpful for ASP.NET MVC:

In an MVC app, you have to right-click on Default.aspx, which is the only ‘real’ web page in that solution. The default page displays ‘Browse with…’

Hey, use these section of code.

Path for xampp is: apache\conf\extra\httpd-xampp.conf

 <LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
        Order deny,allow

If you want a string, then the other answers are fine, but if what you're looking for is the first few letters as characters you can access them as a list:

your_text.chars.take(30)

There is no longer a need for creating your own FAB nor using a third party library, it was included in AppCompat 22.

https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html

Just add the new support library called design in in your gradle-file:

compile 'com.android.support:design:22.2.0'

...and you are good to go:

<android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:layout_margin="16dp"
        android:clickable="true"
        android:src="@drawable/ic_happy_image" />

As mentioned by others: git doesn't track folders, only files.

You can ensure a folder exists with these commands (or equivalent logic):

echo "*" > keepthisfolder/.gitignore
git add --force keepthisfolder/.gitignore
git commit -m "adding git ignore file to keepthisfolder"

The existence of the file will mean anyone checking out the repository will have the folder.

The contents of the gitignore file will mean anything in it are ignored

You do not need to not-ignore the .gitignore file itself. It is a rule which would serve no purpose at all once committed.

OR

if you prefer to keep all your ignore definitions in the same place, you can create .gitignore in the root of your project with contents like so:

*.tmp # example, ignore all .tmp files in any folder
path/to/keepthisfolder
path/to/keepthatfolder

and to ensure the folders exist

touch path/to/keepthisfolder/anything
git add --force path/to/keepthisfolder/anything
git commit -m "ensure keepthisfolder exists when checked out"

"anything" can literally be anything. Common used names are .gitignore, .gitkeep, empty.

Here is a general purpose method which lets you add/subtract any type of unit(Year/Month/Day/Hour/Second etc) in the specified date.

Using Swift 2.2

func addUnitToDate(unitType: NSCalendarUnit, number: Int, date:NSDate) -> NSDate {

    return NSCalendar.currentCalendar().dateByAddingUnit(
        unitType,
        value: number,
        toDate: date,
        options: NSCalendarOptions(rawValue: 0))!

}

print( addUnitToDate(.Day, number: 1, date: NSDate()) ) // Adds 1 Day To Current Date
print( addUnitToDate(.Hour, number: 1, date: NSDate()) ) // Adds 1 Hour To Current Date
print( addUnitToDate(.Minute, number: 1, date: NSDate()) ) // Adds 1 Minute To Current Date

// NOTE: You can use negative values to get backward values too

What exactly do you want to know? ActiveRecord has methods that serialize records into JSON. For instance, open up your rails console and enter ModelName.all.to_json and you will see JSON output. render :json essentially calls to_json and returns the result to the browser with the correct headers. This is useful for AJAX calls in JavaScript where you want to return JavaScript objects to use. Additionally, you can use the callback option to specify the name of the callback you would like to call via JSONP.

For instance, lets say we have a User model that looks like this: {name: 'Max', email:' [email protected]'}

We also have a controller that looks like this:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user
    end
end

Now, if we do an AJAX call using jQuery like this:

$.ajax({
    type: "GET",
    url: "/users/5",
    dataType: "json",
    success: function(data){
        alert(data.name) // Will alert Max
    }        
});

As you can see, we managed to get the User with id 5 from our rails app and use it in our JavaScript code because it was returned as a JSON object. The callback option just calls a JavaScript function of the named passed with the JSON object as the first and only argument.

To give an example of the callback option, take a look at the following:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user, callback: "testFunction"
    end
end

Now we can crate a JSONP request as follows:

function testFunction(data) {
    alert(data.name); // Will alert Max
};

var script = document.createElement("script");
script.src = "/users/5";

document.getElementsByTagName("head")[0].appendChild(script);

The motivation for using such a callback is typically to circumvent the browser protections that limit cross origin resource sharing (CORS). JSONP isn't used that much anymore, however, because other techniques exist for circumventing CORS that are safer and easier.

Try this regex:

/^[a-z\d\-_\s]+$/i

remove() has been deprecated. Use deleteOne(), deleteMany() or bulkWrite().

The code I use

TeleBot.deleteMany({chatID: chatID}, function (err, _) {
                if (err) {
                    return console.log(err);
                }
            });

You should check if it's not defined using if (!Array.prototype.indexOf).

Also, your implementation of indexOf is not correct. You must use === instead of == in your if (this[i] == obj) statement, otherwise [4,"5"].indexOf(5) would be 1 according to your implementation, which is incorrect.

I recommend you use the implementation on MDC.

<img> is a replaced element; it has a display value of inline by default, but its default dimensions are defined by the embedded image's intrinsic values, like it were inline-block. You can set properties like border/border-radius, padding/margin, width, height, etc. on an image.

Replaced elements : They're elements whose contents are not affected by the current document's styles. The position of the replaced element can be affected using CSS, but not the contents of the replaced element itself.

Referenece : https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img

Create the following function

CREATE OR REPLACE FUNCTION isnull(text, text) RETURNS text AS 'SELECT (CASE (SELECT $1 "
    "is null) WHEN true THEN $2 ELSE $1 END) AS RESULT' LANGUAGE 'sql'

And it'll work.

You may to create different versions with different parameter types.

find /path/to -regex ".*\.\(jpg\|gif\|png\|jpeg\)" > log

I ran into the same problem. From my solution i came into this. So here is your code:

- root_directory
    - sub_directory_a
        - _common.scss
        - template.scss
    - sub_directory_b
        - more_styles.scss

As far i know if you want to import one scss to another its has to be a partial. When you are importing from different directory name your more_styles.scss to _more_styles.scss. Then import it into your template.scss like this @import ../sub_directory_b/_more_styles.scss. It worked for me. But as you mentioned ../sub_directory_a/_common.scss not working. That's the same directory of the template.scss. That is why it wont work.

1. give your close button an fx:id, if you haven't yet: <Button fx:id="closeButton" onAction="#closeButtonAction">

2. In your controller class:

   @FXML private javafx.scene.control.Button closeButton;
   
   @FXML
   private void closeButtonAction(){
       // get a handle to the stage
       Stage stage = (Stage) closeButton.getScene().getWindow();
       // do what you have to do
       stage.close();
   }
   

If anybody still wants this, Java regex for support Unicode? is a good one. It's for when you want ONLY letters (no matter what encoding - japaneese, sweedish) iside an EditText. Later, you can check it using Matcher and Pattern.compile()

We can add ng-click event conditionally without using disabled class.

HTML:

  <input ng-click="profileForm.$valid && updateMyProfile()" name="submit" id="submit" value="Save" class="submit" type="submit">

If you are not sharing develop branch with anybody, then I would just rebase it every time master updated, that way you will not have merge commits all over your history once you will merge develop back into master. Workflow in this case would be as follows:

> git clone git://<remote_repo_path>/ <local_repo>
> cd <local_repo>
> git checkout -b develop
....do a lot of work on develop
....do all the commits
> git pull origin master
> git rebase master develop

Above steps will ensure that your develop branch will be always on top of the latest changes from the master branch. Once you are done with develop branch and it's rebased to the latest changes on master you can just merge it back:

> git checkout -b master
> git merge develop
> git branch -d develop

Or you can code it:

int[] colors = {0, 0xFFFF0000, 0}; // red for the example
myList.setDivider(new GradientDrawable(Orientation.RIGHT_LEFT, colors));
myList.setDividerHeight(1);

Hope it helps

In Swift the isEmpty function it will check if the string is empty.

 if username.isEmpty || password.isEmpty {
      println("Sign in failed. Empty character")
 }

I had a similar problem in Android Studio 0.2.2 (IntelliJ). On Windows 7 my Nexus 7 did not appear in device chooser although it was fine on my Mac. I could also browse my Nexus 7 in Windows Explorer.

In the end I needed to install the Asus USB drivers for the Nexus 7 (link):

After that ADB detected my Nexus and everything worked as expected.

I believe the answer is very simple and it has to do with semantic rules of references and how arrays are handled in C++.

In short: References can be thought of as structs which don't have a default constructor, so all the same rules apply.

1) Semantically, references don't have a default value. References can only be created by referencing something. References don't have a value to represent the absence of a reference.

2) When allocating an array of size X, program creates a collection of default-initialized objects. Since reference doesn't have a default value, creating such an array is semantically illegal.

This rule also applies to structs/classes which don't have a default constructor. The following code sample doesn't compile:

struct Object
{
    Object(int value) { }
};

Object objects[1]; // Error: no appropriate default constructor available

For those who uses Git Bash and having issues with npm run <script>,

Just set npm to use Git Bash to run scripts

npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe" (change the path according to your installation)

And then npm will run scripts with Git Bash, so such usages like NODE_ENV= will work properly.

My experience with windows client and linux/mysql server:

When sqldev is used in a windows client and mysql is installed in a linux server meaning, sqldev network access to mysql.

Assuming mysql is already up and running and the databases to be accessed are up and functional:

• Ensure the version of sqldev (32 or 64). If 64 and to avoid dealing with path access copy a valid 64 version of msvcr100.dll into directory ~\sqldeveloper\jdev\bin.

a. Open the file msvcr100.dll in notepad and search for first occurrence of “PE “

 i. “PE  d” it is 64.

ii. “PE  L” it is 32.

b. Note: if sqldev is 64 and msvcr100.dll is 32, the application gets stuck at startup.

• For sqldev to work with mysql there is need of the JDBC jar driver. Download it from mysql site.

a. Driver name = mysql-connector-java-x.x.xx

b. Copy it into someplace related to your sqldeveloper directory.

c. Set it up in menu sqldev Tools/Preferences/Database/Third Party JDBC Driver (add entry)

• In Linux/mysql server change file /etc/mysql/mysql.conf.d/mysqld.cnf look for

bind-address = 127.0.0.1 (this linux localhost)

and change to

bind-address = xxx.xxx.xxx.xxx (this linux server real IP or machine name if DNS is up)

• Enter to linux mysql and grant needed access for example

# mysql –u root -p

GRANT ALL ON . to root@'yourWindowsClientComputerName' IDENTIFIED BY 'mysqlPasswd';

flush privileges;

restart mysql - sudo /etc/init.d/mysql restart

• Start sqldev and create a new connection

a. user = root

b. pass = (your mysql pass)

c. Choose MySql tab

 i.   Hostname = the linux IP hostname

 ii.  Port     = 3306 (default for mysql)

 iii. Choose Database = (from pull down the mysql database you want to use)

 iv.  save and connect

That is all I had to do in my case.

Thank you,

Ale

Can be done using numpy where() function:

import pandas as pd
import numpy as np

In [716]: df = pd.DataFrame({"gene_name": ['SLC45A1', 'NECAP2', 'CLIC4', 'ADC', 'AGBL4'] , "BoolCol": [False, True, False, True, True] },
       index=list("abcde"))

In [717]: df
Out[717]: 
  BoolCol gene_name
a   False   SLC45A1
b    True    NECAP2
c   False     CLIC4
d    True       ADC
e    True     AGBL4

In [718]: np.where(df["BoolCol"] == True)
Out[718]: (array([1, 3, 4]),)

In [719]: select_indices = list(np.where(df["BoolCol"] == True)[0])

In [720]: df.iloc[select_indices]
Out[720]: 
  BoolCol gene_name
b    True    NECAP2
d    True       ADC
e    True     AGBL4

Though you don't always need index for a match, but incase if you need:

In [796]: df.iloc[select_indices].index
Out[796]: Index([u'b', u'd', u'e'], dtype='object')

In [797]: df.iloc[select_indices].index.tolist()
Out[797]: ['b', 'd', 'e']

In case you need further info for your log/audit you can OUTPUT clause: This way, not only you keep the number of rows affected, but also what records.

As an example of the Output Clause during inserts: SQL Server list of insert identities

DECLARE @InsertedIDs table(ID int);

INSERT INTO YourTable
    OUTPUT INSERTED.ID
        INTO @InsertedIDs 
    SELECT ...

You can build an eclipse project via a workspace from the command line:

eclipsec.exe -noSplash -data "D:\Source\MyProject\workspace" -application org.eclipse.jdt.apt.core.aptBuild

It uses the jdt apt plugin to build your workspace automatically. This is also known as a 'Headless Build'. Damn hard to figure out. If you're not using a win32 exe, you can try this:

java -cp startup.jar -noSplash -data "D:\Source\MyProject\workspace" -application org.eclipse.jdt.apt.core.aptBuild

Update

Several years ago eclipse replaced startup.jar with the "equinox launcher"

https://wiki.eclipse.org/Equinox_Launcher

On Eclipse Mars (MacOX):

java -jar /Applications/Eclipse.app/Contents/Eclipse/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar -noSplash -data "workspace" -application org.eclipse.jdt.apt.core.aptBuild

The -data parameter specifies the location of your workspace.

The version number for the equinox launcher will depend on what version of eclipse you have.

Uniform Resource Identifier (URI) is a string of characters used to identify a name or a resource on the Internet

A URI identifies a resource either by location, or a name, or both. A URI has two specializations known as URL and URN.

A Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. A URL defines how the resource can be obtained. It does not have to be HTTP URL (http://), a URL can also be (ftp://) or (smb://).

A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the URN scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be both a name and a locator at the same time.

The URNs are part of a larger Internet information architecture which is composed of URNs, URCs and URLs.

bar.html is not a URN. A URN is similar to a person's name, while a URL is like a street address. The URN defines something's identity, while the URL provides a location. Essentially, "what" vs. "where". A URN has to be of this form <URN> ::= "urn:" <NID> ":" <NSS> where <NID> is the Namespace Identifier, and <NSS> is the Namespace Specific String.

To put it differently:

• A URL is a URI that identifies a resource and also provides the means of locating the resource by describing the way to access it
• A URL is a URI
• A URI is not necessarily a URL

I'd say the only thing left to make it 100% clear would be to have an example of an URI that is not an URL. We can use the examples in the RFC3986:

URL: ftp://ftp.is.co.za/rfc/rfc1808.txt
URL: http://www.ietf.org/rfc/rfc2396.txt
URL: ldap://[2001:db8::7]/c=GB?objectClass?one

It looks that even if the driver 10.2 is compatible with the JDBC3 it may not work with JRE6 as I've found here:

Which JDBC drivers support which versions of Javasoft's JDK?

pre-8i OCI and THIN Drivers - JDK 1.0.x and JDK 1.1.x
8.1.5 OCI and THIN Drivers - JDK 1.0.x and JDK 1.1.x
8.1.6SDK THIN Driver - JDK 1.1.x and JDK 1.2.x (aka Java2)
8.1.6SDK OCI Driver - Only JDK 1.1.x
8.1.6 OCI and THIN Driver - JDK 1.1.x and JDK 1.2.x
8.1.7 OCI and THIN Driver - JDK 1.1.x and JDK 1.2.x
9.0.1 OCI and THIN Driver - JDK 1.1.x, JDK 1.2.x and JDK 1.3.x
9.2.0 OCI and THIN Driver - JDK 1.1.x, JDK 1.2.x, JDK 1.3.x, and JDK 1.4.x
10.1.0 OCI and THIN Driver - JDK 1.2.x, JDK 1.3.x, and JDK 1.4.x
10.2.0 OCI and THIN Driver - JDK 1.2.x, JDK 1.3.x, JDK 1.4.x, and JDK 5.0.x
11.1.0 OCI and THIN Driver - JDK 1.5.x and JDK 1.6.x

Oracle 10.2.0 supports:

Full support for JDBC 3.0
Note that there is no real change in the support for the following in the database. Allthat has changed is that some methods that previously threw SQLException now do something more reasonable instead.
result-set holdability
returning multiple result-sets.

I had the same issue with importing matplotlib.pylab with Python 3.5.1 on Win 64. Installing the Visual C++ Redistributable für Visual Studio 2015 from this links: https://www.microsoft.com/en-us/download/details.aspx?id=48145 fixed the missing DLLs.

I find it better and easier than downloading and pasting DLLs.
