Programs & Examples On #Compound file

I used dir /s /b /o:n /a:d, and it worked perfectly, just make sure you let the file finish writing, or you'll have an incomplete list.

You can use Func which encapsulates a method that has one parameter and returns a value of the type specified by the TResult parameter.

void Method()
{
    Func<string,string> inlineFunction = source => 
    {
        // add your functionality here
        return source ;
     };


    // call the inline function
   inlineFunction("prefix");
}

in command line first reach the directory where psql is present then write commands like this:

psql [database name] [username]

and then press enter psql asks for password give the user password:

then write

> \i [full path and file name with extension]

then press enter insertion done.

You can try my implementation of editable combobox http://www.zoonman.com/projects/combobox/

As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &. That also requires using parentheses so that & wouldn't take precedence.

It would go something like this:

mask = ((50  < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...

In order to avoid that, you can build series for lower and upper limits:

low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)

Now you can slice it as follows:

mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]

And for assignment you can use np.where:

df['class'] = np.where(mask, 'excellent', 'critical')

Yes, the upload element is protected from direct manipulation in different browsers. However, you could erase the element from the DOM tree and then insert a new one in its place via JavaScript. That would give you the same result.

Something along the lines of:

$('#container-element').html('<input id="upload-file" type="file"/>');

inline

import functools

#: not key(c) in d
d = {"a": "avalue", "b": "bvalue", "d": "dvalue"}

entitiesToREmove = ('a', 'b', 'c')

#: python2
map(lambda x: functools.partial(d.pop, x, None)(), entitiesToREmove)

#: python3

list(map(lambda x: functools.partial(d.pop, x, None)(), entitiesToREmove))

print(d)
# output: {'d': 'dvalue'}

To me it feels like you have missing header files for popen, which is a C system library.

Check if you have installed xcode successful with the command line tools and have accepted the license.

You have to install the curl binary in your PC first. You can download it from here.

After that unzip it into a folder. Lets say C:\curl. In that folder you'll find curl.exe file with several .dll files.

Now open a command prompt by typing cmd from the start menu. And type cd c:\curl on there and it will take you to the curl folder. Now execute the curl command that you have.

One thing, windows doesn't support single quote around around the fields. So you have to use double quotes. For example I have converted your curl command like appropriate one.

curl -H "Content-Type: application/json" -XPOST "http://localhost:9200/indexname/typename/optionalUniqueId" -d "{ \"field\" : \"value\"}"

Pipe the content of your

Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy"

to fl *

You will see that the path is already being returned as a property of the objects.

IF you want just the path, use select path or select -unique path to remove duplicates:

Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy" | select -unique path

Direct get a count of row

Using Eloquent

 //Useing Eloquent
 $count = Model::count();    

 //example            
 $count1 = Wordlist::count();

Using query builder

 //Using query builder
 $count = \DB::table('table_name')->count();

 //example
 $count2 = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)->count();

Try this code. I also faced the same problem, but some how I solved it.

public class KitchenUserInterface {

    private JFrame frame;
    private JPanel main_panel, northpanel , southpanel;
    private JLabel label;
    private JButton nextOrder;
    private JList list;

    private static KitchenUserInterface kitchenRunner ;

    public void setList(String[] order){
        kitchenRunner.frame.dispose();
        kitchenRunner.frame.setVisible(false);
        kitchenRunner= new KitchenUserInterface(order);

    }

    public KitchenUserInterface getInstance() {
        if(kitchenRunner == null) {
            synchronized(KitchenUserInterface.class) {
                if(kitchenRunner == null) {
                    kitchenRunner = new KitchenUserInterface();
                }
            }
        }


        return this.kitchenRunner;
    }

    private KitchenUserInterface() {


        frame = new JFrame("Lullaby's Kitchen");
        main_panel = new JPanel();
        main_panel.setLayout(new BorderLayout());
        frame.setContentPane(main_panel);



        northpanel = new JPanel();
        northpanel.setLayout(new FlowLayout());


        label = new JLabel("Kitchen");

        northpanel.add(label);


        main_panel.add(northpanel , BorderLayout.NORTH);


        frame.setSize(500 , 500 );
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    private KitchenUserInterface (String[] order){
        this();
        list = new JList<String>(order);
        main_panel.add(list , BorderLayout.CENTER);

        southpanel = new JPanel();
         southpanel.setLayout(new FlowLayout());

         nextOrder = new JButton("Next Order Set");
         nextOrder.addActionListener(new OrderUpListener(list));
         southpanel.add(nextOrder);
         main_panel.add(southpanel, BorderLayout.SOUTH);



    }

    public static void main(String[] args) {
        KitchenUserInterface dat = kitchenRunner.getInstance();
        try{

        Thread.sleep(1500);
        System.out.println("Ready");
        dat.setList(OrderArray.getInstance().getOrders());
        }
        catch(Exception event) {
            System.out.println("Error sleep");
            System.out.println(event);
        }


        }

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

I've created a simple example tutorial. You can read this and use in your application.

http://ribinsandroidhelper.blogspot.in/2013/03/qr-code-reading-on-your-application.html

Through this link you can download the qrcode library project and import into your workspace and add library to your project

and copy this code to your activity

 Intent intent = new Intent("com.google.zxing.client.android.SCAN");
 startActivityForResult(intent, 0);

 public void onActivityResult(int requestCode, int resultCode, Intent intent) {
     if (requestCode == 0) {
         if (resultCode == RESULT_OK) {
             String contents = intent.getStringExtra("SCAN_RESULT");
             String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
             Toast.makeText(this, contents,Toast.LENGTH_LONG).show();
             // Handle successful scan
         } else if (resultCode == RESULT_CANCELED) {
             //Handle cancel
         }
     }
}

There are two setting.xml in windows.

• %MAVEN_HOME%\conf\
• %userprofile%\.m2\

If %userprofile%\.m2\setting.xml takes effect, maven will not access %MAVEN_HOME%\conf\setting.xml.

Remember that settings.py is a live code file. Assuming that you don't have DEBUG set on production (which is a best practice), you can do something like:

if DEBUG:
    STATIC_PATH = /path/to/dev/files
else:
    STATIC_PATH = /path/to/production/files

Pretty basic, but you could, in theory, go up to any level of complexity based on just the value of DEBUG - or any other variable or code check you wanted to use.

Only works for one level Arrays, String or Numbers type

 function isArrayEqual(ar1, ar2) {
     return !ar1.some(item => ar2.indexOf(item) === -1) && ar1.length === ar2.length;
 }

If you're using Vagrant though Homestead, it's possible there was an error mounting the shared folder. It looks like Vagrant takes your files from that folder and swaps out the files that are actually on the host machine on boot, so if there was an error, you're essentially trying to access your Laravel installation from when you first made it (which is why you're only getting "home"- that was generated during installation).

You can easily check this by sshing into your vm and checking the routes/web.php file to see if it's actually your file. If it isn't, exit out and vagrant halt, vagrant up, and look for errors on boot.

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

printf accepts a variable number of arguments. Those can only have Plain Old Data (POD) types. Code that passes anything other than POD to printf only compiles because the compiler assumes you got your format right. %s means that the respective argument is supposed to be a pointer to a char. In your case it is an std::string not const char*. printf does not know it because the argument type goes lost and is supposed to be restored from the format parameter. When turning that std::string argument into const char* the resulting pointer will point to some irrelevant region of memory instead of your desired C string. For that reason your code prints out gibberish.

While printf is an excellent choice for printing out formatted text, (especially if you intend to have padding), it can be dangerous if you haven't enabled compiler warnings. Always enable warnings because then mistakes like this are easily avoidable. There is no reason to use the clumsy std::cout mechanism if the printf family can do the same task in a much faster and prettier way. Just make sure you have enabled all warnings (-Wall -Wextra) and you will be good. In case you use your own custom printf implementation you should declare it with the __attribute__ mechanism that enables the compiler to check the format string against the parameters provided.

@Override

Specific to XCode 9.1:
You can refere to @Krunal's answer above or follow below steps

its bit tricky to adjust Simulator size.

If you want to zoom your simulator screen follow below steps :

• Goto Window->Uncheck Show Device Bezels

• Goto Window->select zoom

after doing this you can resize your simulator by dragging edges of simulator.

Pixel Accurate : Its to display your simulator in same size as Physical device pixels, if your screen size doesn't have enough resolution to cover dimension it would not enable Pixel Accurate option.

Alternate is change simulator to landscape mode by clicking ? + ? ,then you could click ? + 2 to select Pixel Accurate option (make sure you have disable Show Device Bezels to reduce size.

I don't think you're supposed to be able to do this, but I have successfully injected a service into a config block. (AngularJS v1.0.7)

I had this problem aswell (The error occurred both on VS 15 and 17). However on VS15 it returned a CONNECTION_REFUSED error and on VS17 it returned ASP.NET Core 1.0 on IIS error 502.5.

FIX

1. Navigate to your project directory and locate the hidden folder .vs (it's located in the projects folder dir). (Remember to show hidden files/folders)

2. Close VS

3. Delete .vs-folder
4. Start VS as admin (.vs-folder will be recreated by VS)

For JSON Post:

var stringContent = new StringContent(json, Encoding.UTF8, "application/json");
var response = await httpClient.PostAsync("http://www.sample.com/write", stringContent);

Non-JSON:

var stringContent = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("field1", "value1"),
    new KeyValuePair<string, string>("field2", "value2"),

Yes, "invalid column" this error raised from the line "select company, stepid, fieldid, NewColumn from #Results".

There are two phases of runing t-sql,

first, parsing, in this phase the sql server check the correction of you submited sql string, including column of table, and optimized your query for fastest retreival.

second, running, retreiving the datas.

If table #Results exists then parsing process will check the columns you specified are valid or not, else (table doesn't exist) parsing will be by passsed the checking columns as you specified.

Most people are using gson : check this

Gson gson = new Gson();
String json = gson.toJson(myObj);

This will definately work for you.

If your compiler supports C++0x and using it is an option for you, then the new standard <random> header is likely to meet your needs. It has a high quality uniform_int_distribution which will accept minimum and maximum bounds (inclusive as you need), and you can choose among various random number generators to plug into that distribution.

Here is code that generates a million random ints uniformly distributed in [-57, 365]. I've used the new std <chrono> facilities to time it as you mentioned performance is a major concern for you.

#include <iostream>
#include <random>
#include <chrono>

int main()
{
    typedef std::chrono::high_resolution_clock Clock;
    typedef std::chrono::duration<double> sec;
    Clock::time_point t0 = Clock::now();
    const int N = 10000000;
    typedef std::minstd_rand G;
    G g;
    typedef std::uniform_int_distribution<> D;
    D d(-57, 365);
    int c = 0;
    for (int i = 0; i < N; ++i) 
        c += d(g);
    Clock::time_point t1 = Clock::now();
    std::cout << N/sec(t1-t0).count() << " random numbers per second.\n";
    return c;
}

For me (2.8 GHz Intel Core i5) this prints out:

2.10268e+07 random numbers per second.

You can seed the generator by passing in an int to its constructor:

    G g(seed);

If you later find that int doesn't cover the range you need for your distribution, this can be remedied by changing the uniform_int_distribution like so (e.g. to long long):

    typedef std::uniform_int_distribution<long long> D;

If you later find that the minstd_rand isn't a high enough quality generator, that can also easily be swapped out. E.g.:

    typedef std::mt19937 G;  // Now using mersenne_twister_engine

Having separate control over the random number generator, and the random distribution can be quite liberating.

I've also computed (not shown) the first 4 "moments" of this distribution (using minstd_rand) and compared them to the theoretical values in an attempt to quantify the quality of the distribution:

min = -57
max = 365
mean = 154.131
x_mean = 154
var = 14931.9
x_var = 14910.7
skew = -0.00197375
x_skew = 0
kurtosis = -1.20129
x_kurtosis = -1.20001

(The x_ prefix refers to "expected")

Just check the length of files property, which is a FileList object contained on the input element

if( document.getElementById("videoUploadFile").files.length == 0 ){
    console.log("no files selected");
}

You can use the event.target.result to reset the input from a component directly.

event.target.value = ""

The issue you have encountered is that UDFs cannot modify the Excel environment, they can only return a value to the calling cell.

There are several alternatives

1. For the sample given you don't actually need VBA. This formula will work
   ='C:\Users\UserName\Desktop\[TestSample.xlsx]Sheet1'!$B$2

2. Use a rather messy work around: See this answer

3. You can use ExecuteExcel4Macro or OLEDB

include them with this order this will work i dont know why :D

I realise this annoying thing too since latest m2e-android plugin upgrade (version 0.4.2), it happens in both new project creation and existing project import (if you don't use src/test/java).

It looks like m2e-android (or perhaps m2e) now always trying to add src/test/java as a source folder, regardless of whether it is actually existed in your project directory, in the .classpath file:

<classpathentry kind="src" output="bin/classes" path="src/test/java">
  <attributes>
    <attribute name="maven.pomderived" value="true"/>
  </attributes>
</classpathentry>

As it is already added in the project metadata file, so if you trying to add the source folder via Eclipse, Eclipse will complain that the classpathentry is already exist:

There are several ways to fix it, the easiest is manually create src/test/java directory in the file system, then refresh your project by press F5 and run Maven -> Update Project (Right click project, choose Maven -> Update Project...), this should fix the missing required source folder: 'src/test/java' error.

You have a sintax error in your code:

try changing this line

$out.='<option value=''.$key.'">'.$value["name"].';

with

$out.='<option value="'.$key.'">'.$value["name"].'</option>';

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

There are only two ways:

• If the memory pointer to by your char * represents a C string (that is, it contains characters that have a 0-byte to mark its end), you can use strlen(a).

• Otherwise, you need to store the length somewhere. Actually, the pointer only points to one char. But we can treat it as if it points to the first element of an array. Since the "length" of that array isn't known you need to store that information somewhere.

They refer to the same element, the difference is that when you say document.body you are passing the element directly to jQuery. Alternatively, when you pass the string 'body', the jQuery selector engine has to interpret the string to figure out what element(s) it refers to.

In practice either will get the job done.

If you are interested, there is more information in the documentation for the jQuery function.

Add this to your CSS:

ul { list-style-position: inside; }

This will place the li elements in the same indent as other paragraphs and text.

Ref: http://www.w3schools.com/cssref/pr_list-style-position.asp

Just because this sort of thing is fun for me, here are two more solutions.

Split into words, initial-cap each word from the split groups, and rejoin. This will change the white space separating the words into a single white space, no matter what it was.

s = 'the brown fox'
lst = [word[0].upper() + word[1:] for word in s.split()]
s = " ".join(lst)

EDIT: I don't remember what I was thinking back when I wrote the above code, but there is no need to build an explicit list; we can use a generator expression to do it in lazy fashion. So here is a better solution:

s = 'the brown fox'
s = ' '.join(word[0].upper() + word[1:] for word in s.split())

Use a regular expression to match the beginning of the string, or white space separating words, plus a single non-whitespace character; use parentheses to mark "match groups". Write a function that takes a match object, and returns the white space match group unchanged and the non-whitespace character match group in upper case. Then use re.sub() to replace the patterns. This one does not have the punctuation problems of the first solution, nor does it redo the white space like my first solution. This one produces the best result.

import re
s = 'the brown fox'

def repl_func(m):
    """process regular expression match groups for word upper-casing problem"""
    return m.group(1) + m.group(2).upper()

s = re.sub("(^|\s)(\S)", repl_func, s)


>>> re.sub("(^|\s)(\S)", repl_func, s)
"They're Bill's Friends From The UK"

I'm glad I researched this answer. I had no idea that re.sub() could take a function! You can do nontrivial processing inside re.sub() to produce the final result!

Insert the item currently at oldIndex to be at newIndex and then remove the original instance.

list.Insert(newIndex, list[oldIndex]);
if (newIndex <= oldIndex) ++oldIndex;
list.RemoveAt(oldIndex);

You have to take into account that the index of the item you want to remove may change due to the insertion.

$(function () {
    $( ".droppable-area" ).sortable({
                connectWith: ".connected-sortable",
                containment: ".droppable-area", //(parent div)
                stack: '.connected-sortable div'
            }).disableSelection();
});

As Uriel says, it is meant for a method in an abstract class that should be implemented in child class, but can be used to indicate a TODO as well.

There is an alternative for the first use case: Abstract Base Classes. Those help creating abstract classes.

Here's a Python 3 example:

class C(abc.ABC):
    @abc.abstractmethod
    def my_abstract_method(self, ...):
        ...

When instantiating C, you'll get an error because my_abstract_method is abstract. You need to implement it in a child class.

TypeError: Can't instantiate abstract class C with abstract methods my_abstract_method

Subclass C and implement my_abstract_method.

class D(C):
    def my_abstract_method(self, ...):
        ...

Now you can instantiate D.

C.my_abstract_method does not have to be empty. It can be called from D using super().

An advantage of this over NotImplementedError is that you get an explicit Exception at instantiation time, not at method call time.

I'm also looking for the same solution. And I think of

BtnventCss.CssClass = BtnventCss.CssClass + " hom_but_a";

It seems working fine but I'm not sure if it is a good practice

If you are using ThreetenABP date library bt Jake Warthon you can do:

dayOfWeek.getDisplayName(TextStyle.FULL, Locale.getDefault()

Remove your dependency on System.Runtime in your Web.Config, it worked for me:

<dependentAssembly>
        <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.10.0" newVersion="4.0.10.0" />
</dependentAssembly>

My guess is that here

<context:component-scan base-package="pl.com.radzikowski.webmail" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>

all annotations are first disabled by use-default-filters="false" and then only @Controller annotation enabled. Thus, your @Component annotation is not enabled.

As per Ammoq and kupa's answers, We use number(1) with default of 0 and don't allow nulls.

here's an add column to demonstrate:

ALTER TABLE YourSchema.YourTable ADD (ColumnName NUMBER(1) DEFAULT 0 NOT NULL);

Hope this helps someone.

You can use the Membership Operator isCase() which is another groovy way:

assert Date.isCase(new Date())

1. Copy config.sample.inc.php to config.inc.php.

   In most cases you will find the config file

   • on linux: /etc/phpmyadmin/config.inc.php
   • on mac: /Library/WebServer/Documents/phpmyadmin/config.inc.php

2. If you are trying to log in as root, you should have the following lines in your config:

   $cfg['Servers'][$i]['user'] = 'root';
   $cfg['Servers'][$i]['AllowNoPassword'] = true;

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

The order of initialization doesn’t matter. All fields are initialized in the order of their definition in their class/struct. But if the order in initialization list is different gcc/g++ generate this warning. Only change the initialization order to avoid this warning. But you can't define field using in initialization before its construct. It will be a runtime error. So you change the order of definition. Be careful and keep attention!

Use this

openssl ciphers -v | awk '{print $2}' | sort | uniq

Autoplay works only with /v/ instead of /embed/, so change the src to:

src="//www.youtube.com/v/qUJYqhKZrwA?autoplay=1&showinfo=0&controls=0"

What is a DLL?

DLL files are binary files that can contain executable code and resources like images, etc. Unlike applications, these cannot be directly executed, but an application will load them as and when they are required (or all at once during startup).

Are they important?

Most applications will load the DLL files they require at startup. If any of these are not found the system will not be able to start the process at all.

DLL files might require other DLL files

In the same way that an application requires a DLL file, a DLL file might be dependent on other DLL files itself. If one of these DLL files in the chain of dependency is not found, the application will not load. This is debugged easily using any dependency walker tools, like Dependency Walker.

There are so many of them in the system folders

Most of the system functionality is exposed to a user program in the form of DLL files as they are a standard form of sharing code / resources. Each functionality is kept separately in different DLL files so that only the required DLL files will be loaded and thus reduce the memory constraints on the system.

Installed applications also use DLL files

DLL files also becomes a form of separating functionalities physically as explained above. Good applications also try to not load the DLL files until they are absolutely required, which reduces the memory requirements. This too causes applications to ship with a lot of DLL files.

DLL Hell

However, at times system upgrades often breaks other programs when there is a version mismatch between the shared DLL files and the program that requires them. System checkpoints and DLL cache, etc. have been the initiatives from M$ to solve this problem. The .NET platform might not face this issue at all.

How do we know what's inside a DLL file?

You have to use an external tool like DUMPBIN or Dependency Walker which will not only show what publicly visible functions (known as exports) are contained inside the DLL files and also what other DLL files it requires and which exports from those DLL files this DLL file is dependent upon.

How do we create / use them?

Refer the programming documentation from your vendor. For C++, refer to LoadLibrary in MSDN.

If you're OK with not using <p>s (only <div>s and <span>s), this solution might even allow you to align your inline-blocks center or right, if you want to (or just keep them left, the way you originally asked for). While the solution might still work with <p>s, I don't think the resulting HTML code would be quite correct, but it's up to you anyways.

The trick is to wrap each one of your <span>s with a corresponding <div>. This way we're taking advantage of the line break caused by the <div>'s display: block (default), while still keeping the visual green box tight to the limits of the text (with your display: inline-block declaration).

.text span {_x000D_
   background:rgba(165, 220, 79, 0.8);_x000D_
   display:inline-block;_x000D_
   padding:7px 10px;_x000D_
   color:white;_x000D_
}_x000D_
.large {  font-size:80px }

<div class="text">_x000D_
  <div><span class="medium">We</span></div>_x000D_
  <div><span class="large">build</span></div>_x000D_
  <div><span class="medium">the</span></div>_x000D_
  <div><span class="large">Internet</span></div>_x000D_
</div>

Use the MV* Pattern

Based on the example you attached, It's better in angular to use the following tools:

• ng-click - evaluates the expression when the element is clicked (Read More)
• ng-class - place a class based on the a given boolean expression (Read More)

for example:

<button ng-click="enabled=true">Click Me!</button>

<div ng-class="{'alpha':enabled}"> 
    ...
</div>

This gives you an easy way to decouple your implementation. e.g. you don't have any dependency between the div and the button.

Read this to learn about the MV* Pattern

Using a robomongo shell script:

//on the same db
var cursor = db.collectionname.find();

while (cursor.hasNext()) {
    var record = cursor.next();   
    db.new_collectionname.save(record);
}

Using mongodb's export and import command

You can add the --jsonArray parameter / flag to your mongoexport command, this exports the result as single json array.

Then just specify the --jsonArray flag again when importing.

Or remove the starting and ending array brackets [] in the file, then your modified & exported file will import with the mongoimport command without the --jsonArray flag.

More on Export here: https://docs.mongodb.org/manual/reference/program/mongoexport/#cmdoption--jsonArray

Import here: https://docs.mongodb.org/manual/reference/program/mongoimport/#cmdoption--jsonArray

I had the same problem too. I used this code:

Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);

Using the ADM, add the images on the sdcard or anywhere.

And when you are in your vm and the selection screen shows up, browse using the top left dropdown seen in the image below.

try this code:

string value = "100";
value = value.Contains(".") ? value.TrimStart('0').TrimEnd('0').TrimEnd('.') : value.TrimStart('0');

It seems that the extension cannot be found anymore using "Visual Studio Team Services". Instead, by following the link in Using Visual Studio Code & Team Foundation Version Control on "Get the TFVC plugin working in Visual Studio Code" you get to the Azure Repos Extension for Visual Studio Code GitHub. There it is explained that you now have to look for "Team Azure Repos".

Also, please note, that with the new Settings editor in Visual Studio Code the additional slashes do not have to be added. The path to tf.exe for VS 2017 - if specified using the "user friendly" Settings editor - would be just

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

From Python Documentation:

An except clause may name multiple exceptions as a parenthesized tuple, for example

except (IDontLikeYouException, YouAreBeingMeanException) as e:
    pass

Or, for Python 2 only:

except (IDontLikeYouException, YouAreBeingMeanException), e:
    pass

Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated and does not work in Python 3; now you should be using as.

That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.

There are several methods, two of which are as follows. Provide a custom installer or a setup project.

Here is how to create a custom installer

[RunInstaller(true)]
public class MyInstaller : Installer
{
    public HelloInstaller()
        : base()
    {
    }

    public override void Commit(IDictionary mySavedState)
    {
        base.Commit(mySavedState);
        System.IO.File.CreateText("Commit.txt");
    }

    public override void Install(IDictionary stateSaver)
    {
        base.Install(stateSaver);
        System.IO.File.CreateText("Install.txt");
    }

    public override void Uninstall(IDictionary savedState)
    {
        base.Uninstall(savedState);
        File.Delete("Commit.txt");
        File.Delete("Install.txt");
    }

    public override void Rollback(IDictionary savedState)
    {
        base.Rollback(savedState);
        File.Delete("Install.txt");
    }
}

To add a setup project

• Menu file -> New -> Project --> Other Projects Types --> Setup and Deployment

• Set properties of the project, using the properties window

The article How to create a Setup package by using Visual Studio .NET provides the details.

It is certainly not efficient for this particular purpose, but what I often do in these situations is to insert indicator variables in each data.frame and then merge:

a1$included_a1 <- TRUE
a2$included_a2 <- TRUE
res <- merge(a1, a2, all=TRUE)

missing values in included_a1 will note which rows are missing in a1. similarly for a2.

One problem with your solution is that the column orders must match. Another problem is that it is easy to imagine situations where the rows are coded as the same when in fact are different. The advantage of using merge is that you get for free all error checking that is necessary for a good solution.

Recently I came across a very elegant solution that take in random JSON that you have no idea the structure:

    [HttpPost]
    public JsonResult Test([FromBody] JsonElement json)
    {
        return Json(json);
    }

Just that easy.

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

Webkit only solution

Quick solution, relies on the -webkit-mask-image property. -webkit-mask-image sets a mask image for an element.

There are a few gotchas with this method:

• Obviously, only works in Webkit browsers
• Requires an additional wrapper to apply the :after psuedo-element (IMG tags can't have :before/:after pseudo elements, grr)
• Because there's an additional wrapper, I'm not sure how to use the attr(…) CSS function to get the IMG tag URL, so it's hard-coded into the CSS separately.

If you can look past those issues, this might be a possible solution. SVG filters will be even more flexible, and Canvas solutions will be even more flexible and have a wider range of support (SVG doesn't have Android 2.x support).

$json = file_get_contents('url_here');
$obj = json_decode($json);
echo $obj->access_token;

For this to work, file_get_contents requires that allow_url_fopen is enabled. This can be done at runtime by including:

ini_set("allow_url_fopen", 1);

You can also use curl to get the url. To use curl, you can use the example found here:

$ch = curl_init();
// IMPORTANT: the below line is a security risk, read https://paragonie.com/blog/2017/10/certainty-automated-cacert-pem-management-for-php-software
// in most cases, you should set it to true
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);
echo $obj->access_token;

It turns out that there is a float: left property by default on all navbar-nav>li elements, which is why they were all scrunching up to the left. Once I added the code below, it made the navbar both centered and not scrunched up.

.navbar-nav>li {
        float: none;
}

Hope this helps someone else who's looking to center a navbar.

In your HTML code

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

In your Typescript code

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

This works perfectly, it does not give any error.

2) unzip the file and go to sqljdbc_version\fra\auth\x86 or \x64
3) copy the sqljdbc_auth.dll to C:\Program Files\Java\jre_Version\bin
4) Finally restart eclipse

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

If you want to exclude a sensitive case column like the password for example, I do this to hide the value :

SELECT * , "" as password FROM tableName;

var postdata = {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"};

var data = [];
data.push(postdata);

console.log(data);

If there is no instance available then .class syntax is used to get the corresponding Class object for a class otherwise you can use getClass() method to get Class object. Since, there is no instance of primitive data type, we have to use .class syntax for primitive data types.

    package test;

    public class Test {
       public static void main(String[] args)
       {
          //there is no instance available for class Test, so use Test.class
          System.out.println("Test.class.getName() ::: " + Test.class.getName());

          // Now create an instance of class Test use getClass()
          Test testObj = new Test();
          System.out.println("testObj.getClass().getName() ::: " + testObj.getClass().getName());

          //For primitive type
          System.out.println("boolean.class.getName() ::: " + boolean.class.getName());
          System.out.println("int.class.getName() ::: " + int.class.getName());
          System.out.println("char.class.getName() ::: " + char.class.getName());
          System.out.println("long.class.getName() ::: " + long.class.getName());
       }
    }

Sadly no, there is no such thing as drop if exists, or CREATE IF NOT EXIST

You could write a plsql script to include the logic there.

http://download.oracle.com/docs/cd/B12037_01/server.101/b10759/statements_9003.htm

I'm not much into Oracle Syntax, but i think @Erich's script would be something like this.

declare 
cant integer
begin
select into cant count(*) from dba_tables where table_name='Table_name';
if count>0 then
BEGIN
    DROP TABLE tableName;
END IF;
END;

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

Old question, but apparently Google likes it so I thought I put an answer down here after some research about this problem.

If you create a figure from scratch you can give it a size option while creation:

import matplotlib.pyplot as plt

fig = plt.figure(figsize=(3, 6))

plt.plot(range(10)) #plot example
plt.show() #for control

fig.savefig('temp.png', dpi=fig.dpi)

figsize(width,height) adjusts the absolute dimension of your plot and helps to make sure both plots look the same.

As stated in another answer the dpi option affects the relative size of the text and width of the stroke on lines, etc. Using the option dpi=fig.dpi makes sure the relative size of those are the same both for show() and savefig().

Alternatively the figure size can be changed after creation with:

fig.set_size_inches(3, 6, forward=True)

forward allows to change the size on the fly.

If you have trouble with too large borders in the created image you can adjust those either with:

plt.tight_layout()
#or:
plt.tight_layout(pad=2)

or:

fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight')
#or:
fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight', pad_inches=0.5)

The first option just minimizes the layout and borders and the second option allows to manually adjust the borders a bit. These tips helped at least me to solve my problem of different savefig() and show() images.

I think that your reasoning is sound. But in practice I have found that it is far more common to omit the === comparison. I think that there are three reasons for that:

1. It does not usually add to the meaning of the expression - that's in cases where the value is known to be boolean anyway.
2. Because there is a great deal of type-uncertainty in JavaScript, forcing a type check tends to bite you when you get an unexpected undefined or null value. Often you just want your test to fail in such cases. (Though I try to balance this view with the "fail fast" motto).
3. JavaScript programmers like to play fast-and-loose with types - especially in boolean expressions - because we can.

Consider this example:

var someString = getInput();
var normalized = someString && trim(someString);  
// trim() removes leading and trailing whitespace

if (normalized) {
    submitInput(normalized);
}

I think that this kind of code is not uncommon. It handles cases where getInput() returns undefined, null, or an empty string. Due to the two boolean evaluations submitInput() is only called if the given input is a string that contains non-whitespace characters.

In JavaScript && returns its first argument if it is falsy or its second argument if the first argument is truthy; so normalized will be undefined if someString was undefined and so forth. That means that none of the inputs to the boolean expressions above are actually boolean values.

I know that a lot of programmers who are accustomed to strong type-checking cringe when seeing code like this. But note applying strong typing would likely require explicit checks for null or undefined values, which would clutter up the code. In JavaScript that is not needed.

Use this CSS:

color: red;

that's all.

A function that allows iterating over both stdout and stderr concurrently, in realtime, line by line

In case you need to get the output stream for both stdout and stderr at the same time, you can use the following function.

The function uses Queues to merge both Popen pipes into a single iterator.

Here we create the function read_popen_pipes():

from queue import Queue, Empty
from concurrent.futures import ThreadPoolExecutor


def enqueue_output(file, queue):
    for line in iter(file.readline, ''):
        queue.put(line)
    file.close()


def read_popen_pipes(p):

    with ThreadPoolExecutor(2) as pool:
        q_stdout, q_stderr = Queue(), Queue()

        pool.submit(enqueue_output, p.stdout, q_stdout)
        pool.submit(enqueue_output, p.stderr, q_stderr)

        while True:

            if p.poll() is not None and q_stdout.empty() and q_stderr.empty():
                break

            out_line = err_line = ''

            try:
                out_line = q_stdout.get_nowait()
            except Empty:
                pass
            try:
                err_line = q_stderr.get_nowait()
            except Empty:
                pass

            yield (out_line, err_line)

read_popen_pipes() in use:

import subprocess as sp


with sp.Popen(my_cmd, stdout=sp.PIPE, stderr=sp.PIPE, text=True) as p:

    for out_line, err_line in read_popen_pipes(p):

        # Do stuff with each line, e.g.:
        print(out_line, end='')
        print(err_line, end='')

    return p.poll() # return status-code

This is not exactly answering the question, but since every of the solution given here has some drawbacks, I suggest to try to refactor your code a little bit so you need to return only one value.

Case one.

You need something inside as well as outside of your method. Why not calculate it outside and pass it to the method?

Instead of:

[thingA, thingB] = createThings(...);  // just a conceptual syntax of method returning two values, not valid in Java

Try:

thingA = createThingA(...);
thingB = createThingB(thingA, ...);

This should cover most of your needs, since in most situations one value is created before the other and you can split creating them in two methods. The drawback is that method createThingsB has an extra parameter comparing to createThings, and possibly you are passing exactly the same list of parameters twice to different methods.

Case two.

Most obvious solution ever and a simplified version of case one. It's not always possible, but maybe both of the values can be created independently of each other?

Instead of:

[thingA, thingB] = createThings(...);  // see above

Try:

thingA = createThingA(...);
thingB = createThingB(...);

To make it more useful, these two methods can share some common logic:

public ThingA createThingA(...) {
    doCommonThings(); // common logic
    // create thing A
}
public ThingB createThingB(...) {
    doCommonThings(); // common logic
    // create thing B
}

No need to stash.

git checkout -b new_branch_name

does not touch your local changes. It just creates the branch from the current HEAD and sets the HEAD there. So I guess that's what you want.

--- Edit to explain the result of checkout master ---

Are you confused because checkout master does not discard your changes?

Since the changes are only local, git does not want you to lose them too easily. Upon changing branch, git does not overwrite your local changes. The result of your checkout master is:

M   testing

, which means that your working files are not clean. git did change the HEAD, but did not overwrite your local files. That is why your last status still show your local changes, although you are on master.

If you really want to discard the local changes, you have to force the checkout with -f.

git checkout master -f

Since your changes were never committed, you'd lose them.

Try to get back to your branch, commit your changes, then checkout the master again.

git checkout new_branch
git commit -a -m"edited"
git checkout master
git status

You should get a M message after the first checkout, but then not anymore after the checkout master, and git status should show no modified files.

--- Edit to clear up confusion about working directory (local files)---

In answer to your first comment, local changes are just... well, local. Git does not save them automatically, you must tell it to save them for later. If you make changes and do not explicitly commit or stash them, git will not version them. If you change HEAD (checkout master), the local changes are not overwritten since unsaved.

In IntelliJ 12.1.4 I went through Settings --> Maven --> Importing and made sure the following was selected:

1. Import Maven projects automatically
2. Create IDEA modules for aggregator projects
3. Keep source...
4. Exclude build dir...
5. Use Maven output...
6. Generated souces folders: "detect automatically"
7. Phase to be...: "process-resources"
8. Automatically download: "sources" & "documentation"
9. Use Maven3 to import project
   • VM options for importer: -Xmx512m

This took me from having a lot of unresolved import statements to having everything resolved. I think the key here was using Maven3 to import project... Hopefully this helps.

This code will suffice your request and I have tested on the sample code.

import csv

with open(in_path, 'r') as f_in, open(out_path, 'w') as f_out:
    csv_reader = csv.reader(f_in, delimiter=';')
    writer = csv.writer(f_out)

    for row in csv_reader:
    writer.writerow(row + [row[0]]

Using sets:

if set(("foo", "bar")).issubset(foo):
    #do stuff

Alternatively:

if set(("foo", "bar")) <= set(foo):
    #do stuff

• Ctrl + A and then Ctrl+D. Doing this will detach you from the screen session which you can later resume by doing screen -r.

• You can also do: Ctrl+A then type :. This will put you in screen command mode. Type the command detach to be detached from the running screen session.

Don't forget the space before start

pm2 start npm --[space]start

so the correct command is:

pm2 start npm -- start

Check your namespaces. I had and issue with that. I found that out by adding another web service to the project to dup it like you did yours and noticed the namespace was different. I had renamed it at the beginning of the project and it looks like its persisted.

http://encosia.com/using-cors-to-access-asp-net-services-across-domains/

refer the above link for more details on Cross domain resource sharing.

you can try using JSONP . If the API is not supporting jsonp, you have to create a service which acts as a middleman between the API and your client. In my case, i have created a asmx service.

sample below:

ajax call:

$(document).ready(function () {
        $.ajax({
            crossDomain: true,
            type:"GET",
            contentType: "application/json; charset=utf-8",
            async:false,
            url: "<your middle man service url here>/GetQuote?callback=?",
            data: { symbol: 'ctsh' },
            dataType: "jsonp",                
            jsonpCallback: 'fnsuccesscallback'
        });
    });

service (asmx) which will return jsonp:

[WebMethod]
    [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
    public void GetQuote(String symbol,string callback)
    {          

        WebProxy myProxy = new WebProxy("<proxy url here>", true);

        myProxy.Credentials = new System.Net.NetworkCredential("username", "password", "domain");
        StockQuoteProxy.StockQuote SQ = new StockQuoteProxy.StockQuote();
        SQ.Proxy = myProxy;
        String result = SQ.GetQuote(symbol);
        StringBuilder sb = new StringBuilder();
        JavaScriptSerializer js = new JavaScriptSerializer();
        sb.Append(callback + "(");
        sb.Append(js.Serialize(result));
        sb.Append(");");
        Context.Response.Clear();
        Context.Response.ContentType = "application/json";
        Context.Response.Write(sb.ToString());
        Context.Response.End();         
    }

Using Javascript

var elemDiv = document.createElement('div');
elemDiv.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;';
document.body.appendChild(elemDiv);

Using jQuery

$('body').append('<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>');

Have you tried before and after rather than >= and <=? Also, is this a date or a timestamp?

show variables

Show variables like "`secure_file_priv`";

Note: keep your csv file in location given by the above command.

create table assessments (course_code varchar(5),batch_code varchar(7),id_assessment int, assessment_type varchar(10), date int , weight int);

Note: here the 'date' column has some blank values in the csv file.

LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/assessments.csv' 
INTO TABLE assessments
FIELDS TERMINATED BY ',' 
OPTIONALLY ENCLOSED BY '' 
LINES TERMINATED BY '\n' 
IGNORE 1 ROWS 
(course_code,batch_code,id_assessment,assessment_type,@date,weight)
SET date = IF(@date = '', NULL, @date);

Before each of your conditional statements, you could do something like this:

var pagetype = pagetype || false;
if (pagetype === 'something') {
    //do stuff
}

An interface defines public instance properties and methods. Fields are typically private, or at the most protected, internal or protected internal (the term "field" is typically not used for anything public).

As stated by other replies you can define a base class and define a protected property which will be accessible by all inheritors.

One oddity is that an interface can in fact be defined as internal but it limits the usefulness of the interface, and it is typically used to define internal functionality that is not used by other external code.

If there is a reason you can't use the simple solution provided by ennuikiller above, then you will have to use Typeglobs to manipulate file handles. This is way more work. This example copies from the file in $ARGV[0] to that in $ARGV[1]. It defaults to STDIN and STDOUT respectively if files are not specified.

use English;

my $in;
my $out;

if ($#ARGV >= 0){
    unless (open($in,  "<", $ARGV[0])){
      die "could not open $ARGV[0] for reading.";
    }
}
else {
    $in  = *STDIN;
}

if ($#ARGV >= 1){
    unless (open($out, ">", $ARGV[1])){
      die "could not open $ARGV[1] for writing.";
    }
}
else {
    $out  = *STDOUT;
}

while ($_ = <$in>){
    $out->print($_);
}

If the global variable should not be written to by anything, including Vuejs, you can use Object.freeze to freeze your object. Adding it to Vue's viewmodel won't unfreeze it. Another option is to provide Vuejs with a frozen copy of the object, if the object is intended to be written globally but just not by Vue: var frozenCopy = Object.freeze(Object.assign({}, globalObject))

jQuery isn't particularly helpful for sorting, but here's an elegant and efficient solution. Just write a plain JS function that takes the property name and the order (ascending or descending) and calls the native sort() method with a simple comparison function:

var people = [
    {
        "f_name": "john",
        "l_name": "doe",
        "sequence": "0",
        "title" : "president",
        "url" : "google.com",
        "color" : "333333",
    }
    // etc
];

function sortResults(prop, asc) {
    people.sort(function(a, b) {
        if (asc) {
            return (a[prop] > b[prop]) ? 1 : ((a[prop] < b[prop]) ? -1 : 0);
        } else {
            return (b[prop] > a[prop]) ? 1 : ((b[prop] < a[prop]) ? -1 : 0);
        }
    });
    renderResults();
}

Then:

sortResults('l_name', true);

Play with a working example here.

None of the above answers worked for me using git version 1.8.3.msysgit.0 and TortoiseGit 1.8.4.0.

In my particular situation, I have to connect to the remote git repo over HTTPS, using a full blown e-mail address as username. In this situation, wincred did not appear to work.

Using the email address as a part of the repo URL also did not work, as the software seems to be confused by the double appearance of the '@' character in the URL.

I did manage to overcome the problem using winstore. Here is what I did:

• Download winstore from http://gitcredentialstore.codeplex.com/
• Run git-credential-winstore.exe to install it.

This will copy the git-credential-winstore.exe to a local directory and add two lines to your global .gitconfig. You can verify this by examining your global .gitconfig. This is easiest done via right mouse button on a folder, "TortoiseGit > Settings > Git > Edit global .gitconfig". The file should contain two lines like:

    [credential]
        helper = !'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'

• No other TortoiseGit settings are needed under "Network" or "Credential". In particular: the "Credential helper" pull down menu under "Credential" will have gone blank as a result of these configuration lines, since TortoiseGit does not recognize the new helper. Do not set the pull down menu to another value or the global .gitconfig will be overwritten with an incorrect value! (*)

You are now ready to go:

• Try to pull from the remote repository. You will notice an authentication popup asking your username and password, the popup should be visually different from the default TortoiseGit popup. This is a good sign and means winstore works. Enter the correct authentication and the pull should succeed.
• Try the same pull again, and your username and password should no longer be asked.

Done! Enjoy your interactions with the remote repo while winstore takes care of the authentication.

(*) Alternatively, if you don't like the blank selection in the TortoiseGit Credential settings helper pull down menu, you can use the "Advanced" option:

• Go to "TortoiseGit > Settings > Credential"
• Select Credential helper "Advanced"
• Click on the "G" (for global) under Helpers

• Enter the Helper path as below. Note: a regular Windows path notation (e.g. "C:\Users...") will not work here, you have to replicate the exact line that installing winstore created in the global .gitconf without the "helper =" bit.

  !'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'
  

• Click the "Add New/Save" button

The Bash Reference Manual is an authoritative source of information about bash.

Here's an example of testing a variable to see if it exists:

if [ -z "$PS1" ]; then
        echo This shell is not interactive
else
        echo This shell is interactive
fi

(From section 6.3.2.)

Note that the whitespace after the open [ and before the ] is not optional.

Tips for Vim users

I had a script that had several declarations as follows:

export VARIABLE_NAME="$SOME_OTHER_VARIABLE/path-part"

But I wanted them to defer to any existing values. So I re-wrote them to look like this:

if [ -z "$VARIABLE_NAME" ]; then
        export VARIABLE_NAME="$SOME_OTHER_VARIABLE/path-part"
fi

I was able to automate this in vim using a quick regex:

s/\vexport ([A-Z_]+)\=("[^"]+")\n/if [ -z "$\1" ]; then\r  export \1=\2\rfi\r/gc

This can be applied by selecting the relevant lines visually, then typing :. The command bar pre-populates with :'<,'>. Paste the above command and hit enter.

I wrote a bot using an API from ipapi.co, here's how you can get location for an IP address (e.g. 1.2.3.4) in php :

Set header :

$opts = array('http'=>array('method'=>"GET", 'header'=>"User-Agent: mybot.v0.7.1"));
$context = stream_context_create($opts);

Get JSON response

echo file_get_contents('https://ipapi.co/1.2.3.4/json/', false, $context);

of get a specific field (country, timezone etc.)

echo file_get_contents('https://ipapi.co/1.2.3.4/country/', false, $context);

You can use a predefined "qualitative colormap" like this:

from matplotlib.cm import get_cmap

name = "Accent"
cmap = get_cmap(name)  # type: matplotlib.colors.ListedColormap
colors = cmap.colors  # type: list
axes.set_prop_cycle(color=colors)

Tested on matplotlib 3.0.3. See https://github.com/matplotlib/matplotlib/issues/10840 for discussion on why you can't call axes.set_prop_cycle(color=cmap).

A list of predefined qualititative colormaps is available at https://matplotlib.org/gallery/color/colormap_reference.html :

that scp command must be issued on the local command-line, for putty the command is pscp.

The quick answer is to use the .Split('\\') method.

I had the same problem. mysql -u root -p worked for me. It later asks you for a password. You should then enter the password that you had set for mysql. The default password could be password, if you did not set one. More info here.

Part of the problem here is that the strings usually used to represent timezones are not actually unique. "EST" only means "America/New_York" to people in North America. This is a limitation in the C time API, and the Python solution is… to add full tz features in some future version any day now, if anyone is willing to write the PEP.

You can format and parse a timezone as an offset, but that loses daylight savings/summer time information (e.g., you can't distinguish "America/Phoenix" from "America/Los_Angeles" in the summer). You can format a timezone as a 3-letter abbreviation, but you can't parse it back from that.

If you want something that's fuzzy and ambiguous but usually what you want, you need a third-party library like dateutil.

If you want something that's actually unambiguous, just append the actual tz name to the local datetime string yourself, and split it back off on the other end:

d = datetime.datetime.now(pytz.timezone("America/New_York"))
dtz_string = d.strftime(fmt) + ' ' + "America/New_York"

d_string, tz_string = dtz_string.rsplit(' ', 1)
d2 = datetime.datetime.strptime(d_string, fmt)
tz2 = pytz.timezone(tz_string)

print dtz_string 
print d2.strftime(fmt) + ' ' + tz_string

Or… halfway between those two, you're already using the pytz library, which can parse (according to some arbitrary but well-defined disambiguation rules) formats like "EST". So, if you really want to, you can leave the %Z in on the formatting side, then pull it off and parse it with pytz.timezone() before passing the rest to strptime.

Ok. This is an ancient history, but may be my solution could be useful for you or another developers. If I don't want an user press back key in a page (lets say page B called from an page A) and go back to last page (page A), I do next steps:

First, on page A, instead call next page using window.location.href or window.location.replace, I make a call using two commands: window.open and window.close example on page A:

<a href="#"
onclick="window.open('B.htm','B','height=768,width=1024,top=0,left=0,menubar=0,
         toolbar=0,location=0,directories=0,scrollbars=1,status=0');
         window.open('','_parent','');
         window.close();">
      Page B</a>;

All modifiers on window open are just to make up the resulting page. This will open a new window (popWindow) without posibilities of use the back key, and will close the caller page (Page A)

Second: On page B you can use the same proccess if you want this page do the same thing.

Well. This needs the user accept you can open popup windows, but in a controlled system, as if you are programming pages for your work or client, this is easily recommended for the users. Just accept the site as trusted.

You can use a StringWriter to write values to a string. It provides a stream-like syntax (though does not derive from Stream) which works with an underlying StringBuilder.

I also met this problem in a Fragment. And I called startActivityForResult in a DialogFragment.

But now this problem has been resolved:
FragmentClassname.this.startActivityForResult.

After two weeks of searching and trying, the following instructions works in

Eclipse Java EE IDE for Web Developers.

Version: Oxygen.3a Release (4.7.3a) Build id: 20180405-1200

1. Copy Lombok.jar to installation directory my case (/opt/eclipse-spring/)
2. Modify eclipse.ini openFile --launcher.appendVmargs

as follows:

openFile
--launcher.appendVmargs
-vmargs
-javaagent:/opt/eclipse-spring/lombok.jar
-Dosgi.requiredJavaVersion=1.8

......

In build.gradle dependencies, add lombok.jar from file as follows

compileOnly files('/opt/eclipse-spring/lombok.jar')

And yippee, I have a great day coding with lombok.

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

Firstly, follow Energya's instruction:

pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
pip install jupyter_nbextensions_configurator
jupyter nbextensions_configurator enable --user

Second is the key: After opening jupiter notebook, click the Nbextension tab. Now Search "colla" from the searching tool provided by Nbextension(not by the web browser), then you will find something called "Collapsible Headings"

This is what you want!

GhostDoc!

Right-click on the function, select "Document this" and

private bool FindTheFoo(int numberOfFoos)

becomes

/// <summary>
/// Finds the foo.
/// </summary>
/// <param name="numberOfFoos">The number of foos.</param>
/// <returns></returns>
private bool FindTheFoo(int numberOfFoos)

(yes, it is all autogenerated).

It has support for C#, VB.NET and C/C++. It is per default mapped to Ctrl+Shift+D.

Remember: you should add information beyond the method signature to the documentation. Don't just stop with the autogenerated documentation. The value of a tool like this is that it automatically generates the documentation that can be extracted from the method signature, so any information you add should be new information.

That being said, I personally prefer when methods are totally selfdocumenting, but sometimes you will have coding-standards that mandate outside documentation, and then a tool like this will save you a lot of braindead typing.

In case my I try to set up proxy from android studio Appearance & Behaviour => System Settings => HTTP Proxy. But the proxy did not worked out so I click no proxy.

Checking NO PROXY will not remove the proxy setting from the gradle.properties(Global). You need to manually remove it.

So I remove all the properties starting with systemProp for example - systemProp.http.nonProxyHosts=*.local, localhost

Here's a sample:

int main()
{
    char buff[1024] = {0};
    FILE* cvt;
    int status;
    /* Launch converter and open a pipe through which the parent will write to it */
    cvt = popen("converter", "w");
    if (!cvt)
    {
        printf("couldn't open a pipe; quitting\n");
        exit(1)
    }
    printf("enter Fahrenheit degrees: " );
    fgets(buff, sizeof (buff), stdin); /*read user's input */
    /* Send expression to converter for evaluation */
    fprintf(cvt, "%s\n", buff);
    fflush(cvt);
    /* Close pipe to converter and wait for it to exit */
    status=pclose(cvt);
    /* Check the exit status of pclose() */
    if (!WIFEXITED(status))
        printf("error on closing the pipe\n");
    return 0;
}

The important steps in this program are:

1. The popen() call which establishes the association between a child process and a pipe in the parent.
2. The fprintf() call that uses the pipe as an ordinary file to write to the child process's stdin or read from its stdout.
3. The pclose() call that closes the pipe and causes the child process to terminate.

Per HTML syntax, and even HTML5, the following are all valid options:

<option value="&quot;asd">test</option>
<option value="&#34;asd">test</option>
<option value='"asd'>test</option>
<option value='&quot;asd'>test</option>
<option value='&#34;asd'>test</option>
<option value=&quot;asd>test</option>
<option value=&#34;asd>test</option>

Note that if you are using XML syntax the quotes (single or double) are required.

Here's a jsfiddle showing all of the above working.

You need to capture from regex. search for the pattern, if found, retrieve the string using group(index). Assuming valid checks are performed:

>>> p = re.compile("name (.*) is valid")
>>> result = p.search(s)
>>> result
<_sre.SRE_Match object at 0x10555e738>
>>> result.group(1)     # group(1) will return the 1st capture (stuff within the brackets).
                        # group(0) will returned the entire matched text.
'my_user_name'

The following method can be used to get the formatted string of the date which is passed in to it. It'll format the date to say 1st,2nd,3rd,4th .. using SimpleDateFormat in Java. eg:- 1st of September 2015

public String getFormattedDate(Date date){
            Calendar cal=Calendar.getInstance();
            cal.setTime(date);
            //2nd of march 2015
            int day=cal.get(Calendar.DATE);

            switch (day % 10) {
            case 1:  
                return new SimpleDateFormat("d'st' 'of' MMMM yyyy").format(date);
            case 2:  
                return new SimpleDateFormat("d'nd' 'of' MMMM yyyy").format(date);
            case 3:  
                return new SimpleDateFormat("d'rd' 'of' MMMM yyyy").format(date);
            default: 
                return new SimpleDateFormat("d'th' 'of' MMMM yyyy").format(date);
        }

I got same problem recently where $(window).mousewheel was returning undefined

What I did was $(window).on('mousewheel', function() {});

Further to process it I am using:

function (event) {
    var direction = null,
        key;

    if (event.type === 'mousewheel') {
        if (yourFunctionForGetMouseWheelDirection(event) > 0) {
            direction = 'up';
        } else {
            direction = 'down';
        }
    }
}

A degree of control is possible over how information travels from a third-party website to Facebook when a page is shared (or liked, etc.). In order to make this possible, information is sent via Open Graph meta tags in the <head> part of the website’s code.

If you want a UTF8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the followed:

public static string Utf16ToUtf8(string utf16String)
{
   /**************************************************************
    * Every .NET string will store text with the UTF16 encoding, *
    * known as Encoding.Unicode. Other encodings may exist as    *

    // Storage for the UTF8 string
    string utf8String = String.Empty;

    // Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
    byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
    byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);

    // Fill UTF8 bytes inside UTF8 string
    for (int i = 0; i < utf8Bytes.Length; i++)
    {
        // Because char always saves 2 bytes, fill char with 0
        byte[] utf8Container = new byte[2] { utf8Bytes[i], 0 };
        utf8String += BitConverter.ToChar(utf8Container, 0);
    }

    // Return UTF8
    return utf8String;
}

In my case the DLL request is a UTF8 string too, but unfortunately the UTF8 string must be interpreted with UTF16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 has to be converted to the UTF16 '–' which is 8211. If you have this case too, you can use the following instead:

public static string Utf16ToUtf8(string utf16String)
{
    // Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
    byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
    byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);

    // Return UTF8 bytes as ANSI string
    return Encoding.Default.GetString(utf8Bytes);
}

Or the Native-Method:

[DllImport("kernel32.dll")]
private static extern Int32 WideCharToMultiByte(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPWStr)] String lpWideCharStr, Int32 cchWideChar, [Out, MarshalAs(UnmanagedType.LPStr)] StringBuilder lpMultiByteStr, Int32 cbMultiByte, IntPtr lpDefaultChar, IntPtr lpUsedDefaultChar);

public static string Utf16ToUtf8(string utf16String)
{
    Int32 iNewDataLen = WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, utf16String.Length, null, 0, IntPtr.Zero, IntPtr.Zero);
    if (iNewDataLen > 1)
    {
        StringBuilder utf8String = new StringBuilder(iNewDataLen);
        WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, -1, utf8String, utf8String.Capacity, IntPtr.Zero, IntPtr.Zero);

        return utf8String.ToString();
    }
    else
    {
        return String.Empty;
    }
}

If you need it the other way around, see Utf8ToUtf16. Hope I could be of help.

To get the user email, you have to log in the user with his Facebook account using the email permission. Use for that the Facebook PHP SDK (see on github) as following.

First check if the user is already logged in :

require "facebook.php";
$facebook = new Facebook(array(
    'appId'  => YOUR_APP_ID,
    'secret' => YOUR_APP_SECRET,
));

$user = $facebook->getUser();
if ($user) {
    try {
        $user_profile = $facebook->api('/me');
    } catch (FacebookApiException $e) {
        $user = null;
    }
}

If he his not, you can display the login link asking for the email permission :

if (!$user) {
    $args = array('scope' => 'email');
    echo '<a href="' . $facebook->getLoginUrl() . '">Login with Facebook</a>';
} else {
    echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>';
}

When he is logged in the email can be found in the $user_profile array.

Hope that helps !

Offering a quick answer for people using Ionic. I need to show a tooltip only once so I used the $localStorage to achieve this. This is for playing a track, so when they push play, it shows the tooltip once.

$scope.storage = $localStorage; //connects an object to $localstorage

$scope.storage.hasSeenPopup = "false";  // they haven't seen it


$scope.showPopup = function() {  // popup to tell people to turn sound on

    $scope.data = {}
    // An elaborate, custom popup
    var myPopup = $ionicPopup.show({
        template: '<p class="popuptext">Turn Sound On!</p>',
        cssClass: 'popup'

    });        
    $timeout(function() {
        myPopup.close(); //close the popup after 3 seconds for some reason
    }, 2000);
    $scope.storage.hasSeenPopup = "true"; // they've now seen it

};

$scope.playStream = function(show) {
    PlayerService.play(show);

    $scope.audioObject = audioObject; // this allow for styling the play/pause icons

    if ($scope.storage.hasSeenPopup === "false"){ //only show if they haven't seen it.
        $scope.showPopup();
    }
}

Case sensitive: document.getElementById (notice the capital B).

I would use the SplFileObject class...

$file = new SplFileObject("filename");

This one works:

<input type="button" value="test" onclick="alert('hey'); alert('ho');" />

And this one too:

function Hey()
{
    alert('hey');
}

function Ho()
{
    alert('ho');
}

.

<input type="button" value="test" onclick="Hey(); Ho();" />

So the answer is - yes you can :) However, I'd recommend to use unobtrusive JavaScript.. mixing js with HTML is just nasty.

Just to add my $.02 here, I ran into a similar issue just yesterday, where 168 of my tests were missing. I tried most everything in this post - most especially making sure my version(s) of NUnit were the same - all to no avail. I then remembered that I had my tests divided into playlists; and these do not update automatically as you add new tests. So, when I deleted the playlists, BAM!, all of my tests were back once more.

One can try Java Operator Overloading. It has its own limitations, but it worth trying if you really want to use operator overloading.

there is one more difference, but only in internet explorer. It occurs when you mix HTML and SVG. if the parent is the 'other' of those two, then .parentNode gives the parent, while .parentElement gives undefined.

Those are optional settings. Leave it set as Unknown and you should be good.

Edit: If "unknown" is no longer an option, try leaving everything in that section blank.

Assuming you want an actual SQL Server MERGE statement:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh);

If you also want to delete records in the target that aren't in the source:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh)
WHEN NOT MATCHED BY SOURCE THEN
    DELETE;

Because this has become a bit more popular, I feel like I should expand this answer a bit with some caveats to be aware of.

First, there are several blogs which report concurrency issues with the MERGE statement in older versions of SQL Server. I do not know if this issue has ever been addressed in later editions. Either way, this can largely be worked around by specifying the HOLDLOCK or SERIALIZABLE lock hint:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
[...]

You can also accomplish the same thing with more restrictive transaction isolation levels.

There are several other known issues with MERGE. (Note that since Microsoft nuked Connect and didn't link issues in the old system to issues in the new system, these older issues are hard to track down. Thanks, Microsoft!) From what I can tell, most of them are not common problems or can be worked around with the same locking hints as above, but I haven't tested them.

As it is, even though I've never had any problems with the MERGE statement myself, I always use the WITH (HOLDLOCK) hint now, and I prefer to use the statement only in the most straightforward of cases.

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get<ResponseOrders >(this.baseUrl,{
       params
    }).pipe(
       map(res => res.results || []),
       catchError(error => _throwError(error.message || error))
    );
} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

So far based on my research JasperSoft has turned out promising open source reporting tool… Matter of fact I am currently working on a huge project wherein I have started converting and building reports using JasperReports/iReports…

Every reporting tool has its own learning curve. The support group from and for Jasper and the quality of response that I have gotten so far is good.

Again at the end of the day it all comes down to what your business / organization needs.

I'm not sure I understand your question.

I just tried this and for byte -12 (signed value) it returned integer 244 (equivalent to unsigned byte value but typed as an int):

  public static int unsignedToBytes(byte b) {
    return b & 0xFF;
  }

  public static void main(String[] args) {
    System.out.println(unsignedToBytes((byte) -12));
  }

Is it what you want to do?

Java does not allow to express 244 as a byte value, as would C. To express positive integers above Byte.MAX_VALUE (127) you have to use a different integral type, like short, int or long.

I might be misunderstanding me, but isn't this exactly what a pivot table does? Do you have the data in a table or just a filtered list? If its not a table make it one (ctrl+l) if it is, then simply activate any cell in the table and insert a pivot table on another sheet. Then Add the columns lastname, firstname, phonenumber to the rows section. Then Add Phone number to the filter section and filter out the null values. Now Sort like normal.

To create a table on the fly us this syntax:

SELECT *
INTO A
FROM dbo.myView

if (myReader["Additional"] != DBNull.Value)
{
    ltlAdditional.Text = "contains data";
}
else
{
     ltlAdditional.Text = "is null";
}

cd /path/to/your/folder
sed -i 's/foo/bar/g' *

Occurrences of "foo" will be replaced with "bar".

On BSD systems like macOS, you need to provide a backup extension like -i '.bak' or else "risk corruption or partial content" per the manpage.

cd /path/to/your/folder

if you are inside the actual function, you can use arguments.callee as a reference to the function. as in:

button.addEventListener('click', function() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', arguments.callee);
});

EDIT: This will not work if you are working in strict mode ("use strict";)

There is an ipython nbextension that constructs a table of contents for a notebook. It seems to only provide navigation, not section folding.

I'm going to assume your host is using C-Panel - and that it's probably HostGator or GoDaddy. In both cases they use C-Panel (in fact, a lot of hosts do) to make the Server administration as easy as possible on you, the end user. Even if you are hosting through someone else - see if you can log in to some kind of admin panel and find an .htaccess file that you can edit. (Note: The period before just means that it's a "hidden" file/directory).

Once you find the htaccess file add the following line:

1. Header set Access-Control-Allow-Origin "*" Just to see if it works. Warning: Do not use this line on a production server

It should work. If not, call your host and ask them why the line isn't working - they'll probably be able to help you quickly from there.

2. Once you do have the above working change the * to the address of the requesting domain http://cyclistinsuranceaustralia.com.au/. You may find an issue with canonical addressing (including the www) and if so you may need to configure your host for a redirect. That's a different and smaller bridge to cross though. You'll at least be in the right place.

The problem sometimes occurs when there are errors in the project.

For instance, if your project is configured with a target of 3.2 but the 3.2 libraries are not available, you will not be able to change the version to 4.0!

The usual (perhaps brutal) solution I use is to create a new project with the correct target and copy src, res and manifest into the new project.

Update:

This seems to work:

1. Change the selected through the build properties as normal
2. Manually edit project.properties AND default.properties to make sure they both reflect the desired target.
3. Close the project and re-open it

I always run Android Tools | Fix Project Properties after making any changes to the build target.

Try this

Cast('7/7/2011' as datetime)

and

Convert(varchar(30),'7/7/2011',102)

See CAST and CONVERT (Transact-SQL) for more details.

Here's a refinement of the Fast/Slow solution, which correctly handles odd length lists and improves clarity.

boolean hasLoop(Node first) {
    Node slow = first;
    Node fast = first;

    while(fast != null && fast.next != null) {
        slow = slow.next;          // 1 hop
        fast = fast.next.next;     // 2 hops 

        if(slow == fast)  // fast caught up to slow, so there is a loop
            return true;
    }
    return false;  // fast reached null, so the list terminates
}

In order to export out the VAR variable first the most logical and seems working way is to source the variable:

. ./export.bash

or

source ./export.bash

Now when echoing from main shell it works

 echo $VAR
HELLO, VARABLE

We will now reset VAR

export VAR=""
echo $VAR

Now we will execute a script to source the variable then unset it :

./test-export.sh 
HELLO, VARABLE
--
.

the code: cat test-export.sh

    #!/bin/bash
    # Source env variable
    source ./export.bash

    # echo out the variable in test script
    echo $VAR

    # unset the variable 
    unset VAR
    # echo a few dotted lines
    echo "---"
    # now return VAR which is blank
    echo $VAR

Here is one way

PLEASE NOTE: The exports are limited to the script that execute the exports in your main console - so as far as a cron job I would add it like the console like below... for the command part still questionable: here is how you would run in from your shell:

On your command prompt (so long as the export.bash has multiple echo values)

IFS=$'\n'; for entries in $(./export.bash); do  export $entries;  done; ./v1.sh 
HELLO THERE
HI THERE

cat v1.sh

#!/bin/bash
echo $VAR
echo $VAR1

Now so long as this is for your usage - you could make the variables available for your scripts at any time by doing a bash alias like this:

myvars ./v1.sh
HELLO THERE
HI THERE

echo $VAR

.

add this to your .bashrc

function myvars() { 
    IFS=$'\n'; 
    for entries in $(./export.bash); do  export $entries;  done; 

    "$@"; 

    for entries in $(./export.bash); do variable=$(echo $entries|awk -F"=" '{print $1}'); unset $variable;
done

}

source your bashrc file and you can do like above any time ...

Anyhow back to the rest of it..

This has made it available globally then executed the script..

simply echo it out then run export on the echo !

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"

Now within script or your console run:

 export "$(./export.bash)"

Try:

echo $VAR
HELLO THERE

Multiple values so long as you know what you are expecting in another script using above method:

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"
echo "VAR1=HI THERE"

cat test-export.sh

#!/bin/bash

IFS=$'\n'
for entries in $(./export.bash); do
   export $entries
done

echo "round 1"
echo $VAR
echo $VAR1

for entries in $(./export.bash); do
     variable=$(echo $entries|awk -F"=" '{print $1}');
     unset $variable
done

echo "round 2"
echo $VAR
echo $VAR1

Now the results

 ./test-export.sh 
round 1
HELLO THERE
HI THERE
round 2


.

and the final final update to auto assign read the VARIABLES:

./test-export.sh 
Round 0 - Export out then find variable name - 
Set current variable to the variable exported then echo its value
$VAR has value of HELLO THERE
$VAR1 has value of HI THERE
round 1 - we know what was exported and we will echo out known variables
HELLO THERE
HI THERE
Round 2 - We will just return the variable names and unset them 
round 3 - Now we get nothing back

The script: cat test-export.sh

#!/bin/bash

IFS=$'\n'
echo "Round 0 - Export out then find variable name - "
echo "Set current variable to the variable exported then echo its value"
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 export $entries
 eval current_variable=\$$variable
 echo "\$$variable has value of $current_variable"
done


echo "round 1 - we know what was exported and we will echo out known variables"
echo $VAR
echo $VAR1

echo "Round 2 - We will just return the variable names and unset them "
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 unset $variable
done

echo "round 3 - Now we get nothing back"
echo $VAR
echo $VAR1

The loop attribute should do it:

<video width="320" height="240" autoplay loop>
  <source src="movie.mp4" type="video/mp4" />
  <source src="movie.ogg" type="video/ogg" />
  Your browser does not support the video tag.
</video>

Should you have a problem with the loop attribute (as we had in the past), listen to the videoEnd event and call the play() method when it fires.

Note1: I'm not sure about the behavior on Apple's iPad/iPhone, because they have some restrictions against autoplay.

Note2: loop="true" and autoplay="autoplay" are deprecated

What really helped me to change the type of the object in MondoDB was just this simple line, perhaps mentioned before here...:

db.Users.find({age: {$exists: true}}).forEach(function(obj) {
    obj.age = new NumberInt(obj.age);
    db.Users.save(obj);
});

Users are my collection and age is the object which had a string instead of an integer (int32).

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

after trying to fix a similar problem my self, where I had changed from @PrimaryKey(autoGenerate = true) to int UUID, I couldn't find how to write my migration so I changed the table name, it's an easy fix, and ok if you working with a personal/small app

Make sure you do not have a duplicated .env file in the laravel folder. If it exists, delete it. Only keep the .env file.

Endpoint, in the OpenID authentication lingo, is the URL to which you send (POST) the authentication request.

Excerpts from Google authentication API

To get the Google OpenID endpoint, perform discovery by sending either a GET or HEAD HTTP request to https://www.google.com/accounts/o8/id. When using a GET, we recommend setting the Accept header to "application/xrds+xml". Google returns an XRDS document containing an OpenID provider endpoint URL.The endpoint address is annotated as:

<Service priority="0">
<Type>http://specs.openid.net/auth/2.0/server</Type> 
<URI>{Google's login endpoint URI}</URI> 
</Service>

Once you've acquired the Google endpoint, you can send authentication requests to it, specifying the appropriate parameters (available at the linked page). You connect to the endpoint by sending a request to the URL or by making an HTTP POST request.

For python 3.7:

1. On windows command prompt, type: "py -m pip install pip-autoremove". You will get a successful message.

2. Change directory, if you didn't add the following as your PATH: cd C:\Users{user_name}\AppData\Local\Programs\Python\Python37-32\Scripts To know where your package/application has been installed/located, type: "where program_name" like> where jupyter If you didn't find a location, you need to add the location in PATH.

3. Type: pip-autoremove jupyter It will ask to type y/n to confirm the action.

There are others who encountered the problem. Unfortunately, there is only an open issue for excluding files: https://github.com/palantir/tslint/issues/73

So I'm afraid the answer is no.

javascript does not not have a compiler like for example Java/C(You can compare it more to languages like PHP for example). If you want to write compiled code you should read the section about addons and learn C. Although this is rather complex and I don't think you need to do this but instead just write javascript.

OFFSET is what you are looking for.

SELECT * FROM table LIMIT 10 OFFSET 10

Ah yes. Welcome to Asynchronous execution.

Basically, pausing a script would cause the browser and page to become unresponsive for 3 seconds. This is horrible for web apps, and so isn't supported.

Instead, you have to think "event-based". Use setTimeout to call a function after a certain amount of time, which will continue to run the JavaScript on the page during that time.

To view the bootstrap version of a website in your web browser, do the following:

First Method:

• Open the website on your favourite browser
• Press Ctrl + U to view the web page source
• Look at the head section for a file named boostrap.min.js or boostrap.min.css. It should look like this <link href="assets/css/bootstrap.min.css" rel="stylesheet" />
• Then click it to open the source file
• This will display the bootstrap version of the website. It should look like this: Bootstrap v4.4.1 (https://getbootstrap.com/)

Second Method:

• Open the website on your favourite browser
• Press Ctrl + Shift + I to inspect the webpage element
• In the inspect console, click on the Style Editor tab
• And then click on boostrap.min.css
• This will display the bootstrap version of the website. It should look like this: Bootstrap v4.4.1 (https://getbootstrap.com/)

That's all

I hope this helps

My approach:

I first subclass UITextField and add an indexPath property. In the cellFor... Method i hand over the indexPath property.

Then I add following code:

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:textField.indexPath];

CGPoint cellPoint = [cell convertPoint:textField.center toView:self.tableView];
[UIView animateWithDuration:0.3 animations:^(void){self.tableView.contentOffset = CGPointMake(0, cellPoint.y-50);}];

to the textFieldShould/WillBegin...etc.

When the Keyboard disappears you have to reverse it with:

[UIView animateWithDuration:0.3 animations:^(void){self.tableView.contentOffset = CGPointMake(0, 0);}];

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

You may try to check your registry

• HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}

If it is 2.1 version, it will cause cannot load MSCOMCTL.OCX issue.

You may restore to 2.0 verion (not only copy the file, you should unregiser 2.1 and register the restored file)

Or

You may try latest 2.2 version

• https://support.microsoft.com/en-us/kb/3096896 (file date: 5-Nov-2015)
• https://www.microsoft.com/en-us/download/details.aspx?id=50722

Some version information :

• 6.0.88.62 (2.0)
• 6.1.97.82 (2.0)
• 6.1.98.34 (2.1) <<< not work for me
• 6.1.98.46 (2.2)

You can limit the number of lines, or arguments (if there are spaces between each argument) using the --max-lines or --max-args flags, respectively.

  -L max-lines
         Use at most max-lines nonblank input lines per command line.  Trailing blanks cause an input line to be logically continued on the next  input
         line.  Implies -x.

  --max-lines[=max-lines], -l[max-lines]
         Synonym  for  the -L option.  Unlike -L, the max-lines argument is optional.  If max-args is not specified, it defaults to one.  The -l option
         is deprecated since the POSIX standard specifies -L instead.

  --max-args=max-args, -n max-args
         Use at most max-args arguments per command line.  Fewer than max-args arguments will be used if the size (see  the  -s  option)  is  exceeded,
         unless the -x option is given, in which case xargs will exit.

A clean solution could be create a generic class to handle the list, so you don't need to create a different class each time you need it.

public class ListModel<T>
{
    public List<T> Items { get; set; }

    public ListModel(List<T> list) {
        Items = list;
    }
}

and when you return the View you just need to simply do:

List<customClass> ListOfCustomClass = new List<customClass>();
//Do as needed...
return View(new ListModel<customClass>(ListOfCustomClass));

then define the list in the model:

@model ListModel<customClass>

and ready to go:

@foreach(var element in Model.Items) {
  //do as needed...
}

The issue, I believe, is that the Json action result is intended to take an object (your model) and create an HTTP response with content as the JSON-formatted data from your model object.

What you are passing to the controller's Json method, though, is a JSON-formatted string object, so it is "serializing" the string object to JSON, which is why the content of the HTTP response is surrounded by double-quotes (I'm assuming that is the problem).

I think you can look into using the Content action result as an alternative to the Json action result, since you essentially already have the raw content for the HTTP response available.

return this.Content(returntext, "application/json");
// not sure off-hand if you should also specify "charset=utf-8" here, 
//  or if that is done automatically

Another alternative would be to deserialize the JSON result from the service into an object and then pass that object to the controller's Json method, but the disadvantage there is that you would be de-serializing and then re-serializing the data, which may be unnecessary for your purposes.

From the C# programming guide on MSDN:

The parameter of the Main method is a String array that represents the command-line arguments

So, if I had a program (MyApp.exe) like this:

class Program
{
  static void Main(string[] args)
  {
    foreach (var arg in args)
    {
      Console.WriteLine(arg);
    }
  }
}

That I started at the command line like this:

MyApp.exe Arg1 Arg2 Arg3

The Main method would be passed an array that contained three strings: "Arg1", "Arg2", "Arg3".

If you need to pass an argument that contains a space then wrap it in quotes. For example:

MyApp.exe "Arg 1" "Arg 2" "Arg 3"

Command line arguments commonly get used when you need to pass information to your application at runtime. For example if you were writing a program that copies a file from one location to another you would probably pass the two locations as command line arguments. For example:

Copy.exe C:\file1.txt C:\file2.txt

I just wanted to add the fix I found for this issue. I'm not sure why this worked. I had the correct version of jstl (1.2) and also the correct version of servlet-api (2.5)

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

I also had the correct address in my page as suggested in this thread, which is

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

What fixed this issue for me was removing the scope tag from my xml file in the pom for my jstl 1.2 dependency. Again not sure why that fixed it but just in case someone is doing the spring with JPA and Hibernate tutorial on pluralsight and has their pom setup this way, try removing the scope tag and see if that fixes it. Like I said it worked for me.

Enabling a previously-installed Sublime Text package

If you have a subdirectory under Sublime Text 2\Packages for a package that isn't working, you may need to enable it.

1. Preferences > Package Control > Enable Package
2. Select the package you want to enable from the list

I guess you want to read in, ignore the white space, and write it out again. Most XML packages have an option to ignore white space. For example, the DocumentBuilderFactory has setIgnoringElementContentWhitespace for this purpose.

Similarly if you are generating the XML by marshaling an object then JAXB has JAXB_FORMATTED_OUTPUT

Radio buttons are,

<input type="radio" id="radio_1" class="radioButtons" name="radioButton" value="1">

$('.radioButtons').click(function(){

});

You can use os and os.path library easily as follows

import os
os.chdir(os.path.dirname(os.getcwd()))

os.path.dirname returns upper directory from current one. It lets us change to an upper level without passing any file argument and without knowing absolute path.

os.path.dirname(os.path.abspath(myfilename))

This error occurs when you have a Google Services Json file downloaded in your project whose Package name doesn't match with your Project's package name.

Recently renamed the project's package name?

It does update all the classes but not the Gradle File. So check if your package name is correct in your Gradle, and also maybe Manifest too.

And why not just count them ?

import sys
a = sys.argv
if len(a) = 1 :  
    # No arguments were given, the program name count as one
elif len(a) = 4 :
    # Three arguments were given
else :
    # another amount of arguments was given

Yes, there are a few of them.

As we all know storing password in clear text in database is not secure. the bcrypt is a hashing password technique.It is used to built password security. one of the amazing function of bcrypt is it save us from hackers it is used to protect the password from hacking attacks because the password is stored in bcrypted form.

the password_hash() function is used to create a new password hash. It uses a strong & robust hashing algorithm.The password_hash() function is very much compatible with the crypt() function. Therefore, password hashes created by crypt() may be used with password_hash() and vice-versa. The functions password_verify() and password_hash() just the wrappers around the function crypt(), and they make it much easier to use it accurately.

SYNTAX

string password_hash($password , $algo , $options)

The following algorithms are currently supported by password_hash() function:

PASSWORD_DEFAULT PASSWORD_BCRYPT PASSWORD_ARGON2I PASSWORD_ARGON2ID

Parameters: This function accepts three parameters as mentioned above and described below:

password: It stores the password of the user. algo: It is the password algorithm constant that is used continuously while denoting the algorithm which is to be used when the hashing of password takes place. options: It is an associative array, which contains the options. If this is removed and doesn’t include, a random salt is going to be used, and the utilization of a default cost will happen. Return Value: It returns the hashed password on success or False on failure.

Example:

Input : echo password_hash("GFG@123", PASSWORD_DEFAULT); Output : $2y$10$.vGA19Jh8YrwSJFDodbfoHJIOFH)DfhuofGv3Fykk1a

Below programs illustrate the password_hash() function in PHP:

<?php echo password_hash("GFG@123", PASSWORD_DEFAULT); ?>

// Options for the observer (which mutations to observe)
var config = { attributes: true, childList: true };

// Callback function to execute when mutations are observed
var callback = function(mutationsList) {
    for(var mutation of mutationsList) {
        if (mutation.type == 'childList') {
            console.log('A child node has been added or removed.');
        }
        else if (mutation.type == 'attributes') {
            console.log('The ' + mutation.attributeName + ' attribute was modified.');
        }
    }
};

// Create an observer instance linked to the callback function
var observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(targetNode, config);

// Later, you can stop observing
observer.disconnect();
