Found out by adding this to your url parameters

approval_prompt=force

Update:

Use access_type=offline&prompt=consent instead.

approval_prompt=force no longer works https://github.com/googleapis/oauth2client/issues/453

Rich Sutton's answer finally worked for me, after I realized that adding access_type=offline is done on the front end client's request for an authorization code, not the back end request that exchanges that code for an access_token. I've added a comment to his answer and this link at Google for more info about refreshing tokens.

P.S. If you are using Satellizer, here is how to add that option to the $authProvider.google in AngularJS.

If you need to handle both Python 2.x and 3.x you can catch the exception and load the alternative.

try:
    from urllib import quote  # Python 2.X
except ImportError:
    from urllib.parse import quote  # Python 3+

You could also use the python compatibility wrapper six to handle this.

from six.moves.urllib.parse import quote

try this:

select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1

The answers here are worth a try, but you should also review your code. Specifically have a read of Polyfun's answer here: How to get rid of deadlock in a SQL Server 2005 and C# application?

It explains the concurrency issue, and how the usage of "with (updlock)" in your queries might correct your deadlock situation - depending really on exactly what your code is doing. If your code does follow this pattern, this is likely a better fix to make, before resorting to dirty reads, etc.

Now supported in internal-ip!

An RTCPeerConnection can be used. In browsers like Chrome where a getUserMedia permission is required, we can just detect available input devices and request for them.

const internalIp = async () => {
    if (!RTCPeerConnection) {
        throw new Error("Not supported.")
    }

    const peerConnection = new RTCPeerConnection({ iceServers: [] })

    peerConnection.createDataChannel('')
    peerConnection.createOffer(peerConnection.setLocalDescription.bind(peerConnection), () => { })

    peerConnection.addEventListener("icecandidateerror", (event) => {
        throw new Error(event.errorText)
    })

    return new Promise(async resolve => {
        peerConnection.addEventListener("icecandidate", async ({candidate}) => {
            peerConnection.close()
            
            if (candidate && candidate.candidate) {
                const result = candidate.candidate.split(" ")[4]
                if (result.endsWith(".local")) {
                    const inputDevices = await navigator.mediaDevices.enumerateDevices()
                    const inputDeviceTypes = inputDevices.map(({ kind }) => kind)

                    const constraints = {}

                    if (inputDeviceTypes.includes("audioinput")) {
                        constraints.audio = true
                    } else if (inputDeviceTypes.includes("videoinput")) {
                        constraints.video = true
                    } else {
                        throw new Error("An audio or video input device is required!")
                    }

                    const mediaStream = await navigator.mediaDevices.getUserMedia(constraints)
                    mediaStream.getTracks().forEach(track => track.stop())
                    resolve(internalIp())
                }
                resolve(result)
            }
        })
    })

If you want to keep on working with Git as your main repository and just need to "export" the revisions to SVN from time to time, you could use Tailor to keep the SVN repository in sync. It can copy revisions between different source control systems and would update the SVN with the changes you make in Git.

I haven't tried a Git-to-SVN conversion, but for a SVN -> SVN example see this answer.

Here is my implementation for python 3 and pycrypto

from Crypto.PublicKey import RSA
key = RSA.generate(4096)
f = open('/home/john/Desktop/my_rsa_public.pem', 'wb')
f.write(key.publickey().exportKey('PEM'))
f.close()
f = open('/home/john/Desktop/my_rsa_private.pem', 'wb')
f.write(key.exportKey('PEM'))
f.close()

f = open('/home/john/Desktop/my_rsa_public.pem', 'rb')
f1 = open('/home/john/Desktop/my_rsa_private.pem', 'rb')
key = RSA.importKey(f.read())
key1 = RSA.importKey(f1.read())

x = key.encrypt(b"dddddd",32)

print(x)
z = key1.decrypt(x)
print(z)

You can try this:

@OneToOne(orphanRemoval=true) or @OneToMany(orphanRemoval=true).

Just try this func (it may work not only for divs):

function resized(elem, func = function(){}, args = []){
    elem = jQuery(elem);
    func = func.bind(elem);
    var h = -1, w = -1;
    setInterval(function(){
        if (elem.height() != h || elem.width() != w){
            h = elem.height();
            w = elem.width();
            func.apply(null, args);
        }
    }, 100);
}

You can use it like this

resized(/*element*/ '.advs-columns-main > div > div', /*callback*/ function(a){
    console.log(a);
    console.log(this); //for accessing the jQuery element you passed
}, /*callback arguments in array*/ ['I\'m the first arg named "a"!']);

UPDATE: You can also use more progressive watcher (it can work for any objects, not only DOM elements):

function changed(elem, propsToBeChanged, func = function(){}, args = [], interval = 100){
        func = func.bind(elem);
        var currentVal = {call: {}, std: {}};
        $.each(propsToBeChanged, (property, needCall)=>{
            needCall = needCall ? 'call' : 'std';
            currentVal[needCall][property] = new Boolean(); // is a minimal and unique value, its equivalent comparsion with each other will always return false
        });
        setInterval(function(){
            $.each(propsToBeChanged, (property, needCall)=>{
                try{
                    var currVal = needCall ? elem[property]() : elem[property];
                } catch (e){ // elem[property] is not a function anymore
                    var currVal = elem[property];
                    needCall = false;
                    propsToBeChanged[property] = false;
                }
                needCall = needCall ? 'call' : 'std';
                if (currVal !== currentVal[needCall][property]){
                    currentVal[needCall][property] = currVal;
                    func.apply(null, args);
                }
            });
        }, interval);
    }

Just try it:

var b = '2',
    a = {foo: 'bar', ext: ()=>{return b}};
changed(a, {
// prop name || do eval like a function?
    foo:        false,
    ext:        true
}, ()=>{console.log('changed')})

It will log 'changed' every time when you change b, a.foo or a.ext directly

var list = new List<MyClass>();
var item = list.Find( x => x.GetId() == "TARGET_ID" );

or if there is only one and you want to enforce that something like SingleOrDefault may be what you want

var item = list.SingleOrDefault( x => x.GetId() == "TARGET" );

if ( item == null )
    throw new Exception();

Collation can be set at various levels:

1. Server
2. Database
3. Column

So you could have a Case Sensitive Column in a Case Insensitive database. I have not yet come across a situation where a business case could be made for case sensitivity of a single column of data, but I suppose there could be.

Check Server Collation

SELECT SERVERPROPERTY('COLLATION')

Check Database Collation

SELECT DATABASEPROPERTYEX('AdventureWorks', 'Collation') SQLCollation;

Check Column Collation

select table_name, column_name, collation_name
from INFORMATION_SCHEMA.COLUMNS
where table_name = @table_name

Sorry guys, but selecting from all_tab_privs_recd where grantee = 'your user' will not give any output except public grants and current user grants if you run the select from a different (let us say, SYS) user. As documentation says,

ALL_TAB_PRIVS_RECD describes the following types of grants:

Object grants for which the current user is the grantee
Object grants for which an enabled role or PUBLIC is the grantee

So, if you're a DBA and want to list all object grants for a particular (not SYS itself) user, you can't use that system view.

In this case, you must perform a more complex query. Here is one taken (traced) from TOAD to select all object grants for a particular user:

select tpm.name privilege,
       decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
       ue.name grantee,

                       'UNDEFINED') object_type,
       o.name object_name,
       '' column_name
        from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
             table_privilege_map tpm
        where oa.obj# = o.obj#
          and oa.grantor# = ur.user#
          and oa.grantee# = ue.user#
          and oa.col# is null
          and oa.privilege# = tpm.privilege
          and u.user# = o.owner#
          and o.TYPE# in (2, 4, 6, 9, 7, 8, 42, 23, 22, 13, 33, 32, 66, 67, 74, 57)
  and ue.name = 'your user'
  and bitand (o.flags, 128) = 0
union all -- column level grants
select tpm.name privilege,
       decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
       ue.name grantee,
       ur.name grantor,
       u.name owner,
       decode(o.TYPE#, 2, 'TABLE', 4, 'VIEW', 42, 'MATERIALIZED VIEW') object_type,
       o.name object_name,
       c.name column_name
from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
     sys.col$ c, table_privilege_map tpm
where oa.obj# = o.obj#
  and oa.grantor# = ur.user#
  and oa.grantee# = ue.user#
  and oa.obj# = c.obj#
  and oa.col# = c.col#
  and bitand(c.property, 32) = 0 /* not hidden column */
  and oa.col# is not null
  and oa.privilege# = tpm.privilege
  and u.user# = o.owner#
  and o.TYPE# in (2, 4, 42)
  and ue.name = 'your user'
  and bitand (o.flags, 128) = 0;

This will list all object grants (including column grants) for your (specified) user. If you don't want column level grants then delete all part of the select beginning with 'union' clause.

UPD: Studying the documentation I found another view that lists all grants in much simpler way:

select * from DBA_TAB_PRIVS where grantee = 'your user';

Bear in mind that there's no DBA_TAB_PRIVS_RECD view in Oracle.

colorbox has such amazing features..loving it. Also like this one http://www.webappers.com/2008/03/05/galleria-simple-but-nice-jquery-image-gallery/

here is an example for geting a refrence for the root View of a layout , inflating it and using it with setContentView(View view)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LayoutInflater li=getLayoutInflater();
    View rootView=li.inflate(R.layout.activity_main,null);
    setContentView(rootView);


}

grep -oh string * | wc -w

will count multiple occurrences in a line

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

That will remove all <option> elements underneath the dropdown element.

The Redis project does not officially support Windows. However, the Microsoft Open Tech group develops and maintains this Windows port targeting Win64.

It's entirely possible in browser-side javascript.

The easy way:

The readAsDataURL() method might already encode it as base64 for you. You'll probably need to strip out the beginning stuff (up to the first ,), but that's no biggie. This would take all the fun out though.

The hard way:

If you want to try it the hard way (or it doesn't work), look at readAsArrayBuffer(). This will give you a Uint8Array and you can use the method specified. This is probably only useful if you want to mess with the data itself, such as manipulating image data or doing other voodoo magic before you upload.

There are two methods:

• Convert to string and use the built-in btoa or similar
  • I haven't tested all cases, but works for me- just get the char-codes
• Convert directly from a Uint8Array to base64

I recently implemented tar in the browser. As part of that process, I made my own direct Uint8Array->base64 implementation. I don't think you'll need that, but it's here if you want to take a look; it's pretty neat.

What I do now:

The code for converting to string from a Uint8Array is pretty simple (where buf is a Uint8Array):

function uint8ToString(buf) {
    var i, length, out = '';
    for (i = 0, length = buf.length; i < length; i += 1) {
        out += String.fromCharCode(buf[i]);
    }
    return out;
}

From there, just do:

var base64 = btoa(uint8ToString(yourUint8Array));

Base64 will now be a base64-encoded string, and it should upload just peachy. Try this if you want to double check before pushing:

window.open("data:application/octet-stream;base64," + base64);

This will download it as a file.

Other info:

To get the data as a Uint8Array, look at the MDN docs:

• https://developer.mozilla.org/en/DOM/FileReader

Travis-ci and Jenkins, while both are tools for continuous integration are very different.

Travis is a hosted service (free for open source) while you have to host, install and configure Jenkins.

Travis does not have jobs as in Jenkins. The commands to run to test the code are taken from a file named .travis.yml which sits along your project code. This makes it easy to have different test code per branch since each branch can have its own version of the .travis.yml file.

You can have a similar feature with Jenkins if you use one of the following plugins:

• Travis YML Plugin - warning: does not seem to be popular, probably not feature complete in comparison to the real Travis.
• Jervis - a modification of Jenkins to make it read create jobs from a .jervis.yml file found at the root of project code. If .jervis.yml does not exist, it will fall back to using .travis.yml file instead.

There are other hosted services you might also consider for continuous integration (non exhaustive list):

• Circle CI
• Wercker
• drone.io
• Gitlab-CI
• codeship
• shippable
• semaphore

How to choose ?

You might want to stay with Jenkins because you are familiar with it or don't want to depend on 3rd party for your continuous integration system. Else I would drop Jenkins and go with one of the free hosted CI services as they save you a lot of trouble (host, install, configure, prepare jobs)

Depending on where your code repository is hosted I would make the following choices:

• in-house ? Jenkins or gitlab-ci
• Github.com ? Travis-CI

To setup Travis-CI on a github project, all you have to do is:

• add a .travis.yml file at the root of your project
• create an account at travis-ci.com and activate your project

The features you get are:

• Travis will run your tests for every push made on your repo
• Travis will run your tests on every pull request contributors will make

Yes, this is possible and I would like to provide a slight alternative to Rajeev's answer that does not pass a php-generated datetime formatted string to the query.

The important distinction about how to declare the values to be SET in the UPDATE query is that they must not be quoted as literal strings.

To prevent CodeIgniter from doing this "favor" automatically, use the set() method with a third parameter of false.

$userId = 444;
$this->db->set('Last', 'Current', false);
$this->db->set('Current', 'NOW()', false);
$this->db->where('Id', $userId);
// return $this->db->get_compiled_update('Login');  // uncomment to see the rendered query
$this->db->update('Login');
return $this->db->affected_rows();  // this is expected to return the integer: 1

The generated query (depending on your database adapter) would be like this:

UPDATE `Login` SET Last = Current, Current = NOW() WHERE `Id` = 444

Demonstrated proof that the query works: https://www.db-fiddle.com/f/vcc6PfMcYhDD87wZE5gBtw/0

In this case, Last and Current ARE MySQL Keywords, but they are not Reserved Keywords, so they don't need to be backtick-wrapped.

If your precise query needs to have properly quoted identifiers (table/column names), then there is always protectIdentifiers().

You can't, and you shouldn't. That's what polymorphism is for, so that each object has its own way of doing some "base" things.

Console.Read() takes a character and returns the ascii value of that character.So if you want to take the symbol that was entered by the user instead of its ascii value (ex:if input is 5 then symbol = 5, ascii value is 53), you have to parse it using int.parse() but it raises a compilation error because the return value of Console.Read() is already int type. So you can get the work done by using Console.ReadLine() instead of Console.Read() as follows.

int userInput = int.parse(Console.ReadLine());

here, the output of the Console.ReadLine() would be a string containing a number such as "53".By passing it to the int.Parse() we can convert it to int type.

Cleaning project, closing Eclipse, re-opening it and launching my project finally made my R.java to reappear... Hope it helps

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

Your PFX file should contain the private key within it. Export the private key and certificate directly from your PFX file (e.g. using OpenSSL) and import them into your Java keystore.

Edit

Further information:

• Download OpenSSL for Windows here.
• Export private key: openssl pkcs12 -in filename.pfx -nocerts -out key.pem
• Export certificate: openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem

Put your wamp server online

and then go to control panel > system and security > windows firewall and turn windows firewall off

now you can access your wamp server from another computer over local network by the network IP of computer which have wamp server installed like http://192.168.2.34/mysite

if you add an #include <algorithm> then you can use the for_each function and a lambda function like so:

for_each(data.begin(), data.end(), [](Student *it) 
{
    std::cout<<it->name;
});

you can read more about the algorithm library at https://en.cppreference.com/w/cpp/algorithm

and about lambda functions in cpp at https://docs.microsoft.com/en-us/cpp/cpp/lambda-expressions-in-cpp?view=vs-2019

In my case, it was literally a bad USB cable. Apparently it was right on the edge - adb logcat would work, but about half the time I would get this error when trying to push an app to the device.

Changed to a different cable, and everything was fine. The old cable was also very slow at charging, so I should have suspected it sooner...

You might need to stop the "Web Deployment Agent Service"

Press Win+R and type services.msc

Right click on Web Deployment Agent Service and select "Stop"

Restart XAMPP

Also after double clicking "Web Deployment Agent Service" you can make the Startup type to Manual, So that "Web Deployment Agent Service" will not start automatically

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

If all else fails try moving (i.e. in bash) all files and directories "away" and adding them back one by one.

I just found out that way that my .htaccess file was referencing a non-existant .htpasswd file. (#silly)

Well, in java, you can also create a parameterized enum. Say you want to create a className enum, in which you need to store classCode as well as className, you can do that like this:

public enum ClassEnum {

    ONE(1, "One"), 
    TWO(2, "Two"),
    THREE(3, "Three"),
    FOUR(4, "Four"),
    FIVE(5, "Five")
    ;

    private int code;
    private String name;

    private ClassEnum(int code, String name) {
        this.code = code;
        this.name = name;
    }

    public int getCode() {
        return code;
    }

    public String getName() {
        return name;
    }
}

This solution worked well for me: http://www.apachefriends.org/f/viewtopic.php?f=17&t=50902&p=196185#p196185

Edit /opt/lampp/etc/extra/httpd-xampp.conf and adding Require all granted line at bottom of block <Directory "/opt/lampp/phpmyadmin"> to have the following code:

For [1], you can't: these operators are made to return a value, not perform operations.

The expression

a ? b : c

evaluates to b if a is true and evaluates to c if a is false.

The expression

b ?? c

evaluates to b if b is not null and evaluates to c if b is null.

If you write

return a ? b : c;

or

return b ?? c;

they will always return something.

For [2], you can write a function that returns the right value that performs your "multiple operations", but that's probably worse than just using if/else.

It seems as though the "sr-only" element and its styles inside of the table are what's causing this bug. At least I had the same issue and after months of banging our head against the wall that's what we determined the cause was, though I still don't understand why. Adding left:0 to the "sr-only" styles fixed it.

All you are wanting to do is to see if computers are connected to the network and to gather their IP addresses. You can utilize angryIP scanner: http://angryip.org/ to see what IP addresses are in use on a particular subnet or groups of subnets.

I have found this tool very helpful when trying to see what IPs are being used that are not located inside of my DHCP.

I think you can use SeriesGroupBy.nunique:

print (df.groupby('param')['group'].nunique())
param
a    2
b    1
Name: group, dtype: int64

Another solution with unique, then create new df by DataFrame.from_records, reshape to Series by stack and last value_counts:

a = df[df.param.notnull()].groupby('group')['param'].unique()
print (pd.DataFrame.from_records(a.values.tolist()).stack().value_counts())
a    2
b    1
dtype: int64

Firstly, Add this android:debuggable="false" in the application tag of the AndroidManifest.xml.

You don't need to harcode android:debuggable="false" in your application tag. Infact for me studio complaints -

Avoid hardcoding the debug mode; leaving it out allows debug and release builds to automatically assign one less... (Ctrl+F1)

It's best to leave out the android:debuggable attribute from the manifest. If you do, then the tools will automatically insert android:debuggable=true when building an APK to debug on an emulator or device. And when you perform a release build, such as Exporting APK, it will automatically set it to false. If on the other hand you specify a specific value in the manifest file, then the tools will always use it. This can lead to accidentally publishing your app with debug information.

The accepted answer looks somewhat old. For me it asks me to select whether I want debug build or release build.

Go to Build->Generate Signed APK. Select your keystore, provide keystore password etc.

Now you should see a prompt to select release build or debug build.

For production always select release build!

And you are done. Signed APK exported.

PS : Don't forget to increment your versionCode in manifest file before uploading to playstore :)

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

If your float is always expressed in decimal notation something like

>>> import re
>>> re.findall("\d+\.\d+", "Current Level: 13.4 db.")
['13.4']

may suffice.

A more robust version would be:

>>> re.findall(r"[-+]?\d*\.\d+|\d+", "Current Level: -13.2 db or 14.2 or 3")
['-13.2', '14.2', '3']

If you want to validate user input, you could alternatively also check for a float by stepping to it directly:

user_input = "Current Level: 1e100 db"
for token in user_input.split():
    try:
        # if this succeeds, you have your (first) float
        print float(token), "is a float"
    except ValueError:
        print token, "is something else"

# => Would print ...
#
# Current is something else
# Level: is something else
# 1e+100 is a float
# db is something else

I also looked for a simple console replacement, just to dump text. So what I did was this function:

function remoteLog (arg) {
    var file = '/files/remoteLog.php';
    $.post(file, {text: arg});
}

The remote PHP file recorded all the output to a database in arg. It took me 5 minutes (OK, on the server side I used a simple logging library that records and displays text messages, but still...).

I just stumbled upon this question and here is an update for Swift 3 and iOS 10:

let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: nil)
self.navigationItem.rightBarButtonItem  = testUIBarButtonItem

It is definitely much faster than creating the UIButton with all the properties and then subsequently adding the customView to the UIBarButtonItem.

And if you want to change the color of the image from the default blue to e.g. white, you can always change the tint color:

test.tintColor = UIColor.white()

PS You should obviously change the selector etc. for your app :)

It is also worth mentioning that if you're using HtmlAgilityPack like I was, you should use HtmlAgilityPack.HtmlEntity.DeEntitize(). It takes a string and returns a string.

    $(document).ready(function() {
               var referrer =  document.referrer;

               if(referrer.equals("Setting.jsp")){                     
                   function goBack() {  
                        window.history.go();                            
                    }
               }  
                   if(referrer.equals("http://localhost:8080/Ads/Terms.jsp")){                     
                        window.history.forward();
                        function noBack() {
                        window.history.forward(); 
                    }
                   }
    }); 

using this you can avoid load previous page load

To call a sub inside another sub you only need to do:

Call Subname()

So where you have CalculateA(Nc,kij, xi, a1, a) you need to have call CalculateA(Nc,kij, xi, a1, a)

As the which runs first problem it's for you to decide, when you want to run a sub you can go to the macro list select the one you want to run and run it, you can also give it a key shortcut, therefore you will only have to press those keys to run it. Although, on secondary subs, I usually do it as Private sub CalculateA(...) cause this way it does not appear in the macro list and it's easier to work

Hope it helps, Bruno

PS: If you have any other question just ask, but this isn't a community where you ask for code, you come here with a question or a code that isn't running and ask for help, not like you did "It would be great if you could write it in the Excel VBA format."

Or.. Pattern#quote:

String[] value_split = rat_values.split(Pattern.quote("|"));

This is happening because String#split accepts a regex:

| has a special meaning in regex.

quote will return a String representation for the regex.

For anyone facing this issue and ending up on this post...the issue is still open - https://github.com/moby/moby/issues/11185

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

git log origin/master..master

or, more generally:

git log <since>..<until>

You can use this with grep to check for a specific, known commit:

git log <since>..<until> | grep <commit-hash>

Or you can also use git-rev-list to search for a specific commit:

git rev-list origin/master | grep <commit-hash>

The quickest way to do this is using SWIG.

Example from SWIG tutorial:

/* File : example.c */
int fact(int n) {
    if (n <= 1) return 1;
    else return n*fact(n-1);
}

Interface file:

/* example.i */
%module example
%{
/* Put header files here or function declarations like below */
extern int fact(int n);
%}

extern int fact(int n);

Building a Python module on Unix:

swig -python example.i
gcc -fPIC -c example.c example_wrap.c -I/usr/local/include/python2.7
gcc -shared example.o example_wrap.o -o _example.so

Usage:

>>> import example
>>> example.fact(5)
120

Note that you have to have python-dev. Also in some systems python header files will be in /usr/include/python2.7 based on the way you have installed it.

From the tutorial:

SWIG is a fairly complete C++ compiler with support for nearly every language feature. This includes preprocessing, pointers, classes, inheritance, and even C++ templates. SWIG can also be used to package structures and classes into proxy classes in the target language — exposing the underlying functionality in a very natural manner.

The only way to disable network on iOS simulator I know is using tools like Little Snitch or Hands Off. With them you can deny/block any out- and ingoing network connections. You can set it up so that it only blocks connections from the simulator app. Works like a firewall.

Preliminaries

JavaScript has only one data type which can contain multiple values: Object. An Array is a special form of object.

(Plain) Objects have the form

{key: value, key: value, ...}

Arrays have the form

[value, value, ...]

Both arrays and objects expose a key -> value structure. Keys in an array must be numeric, whereas any string can be used as key in objects. The key-value pairs are also called the "properties".

Properties can be accessed either using dot notation

const value = obj.someProperty;

or bracket notation, if the property name would not be a valid JavaScript identifier name ^[spec], or the name is the value of a variable:

// the space is not a valid character in identifier names
const value = obj["some Property"];

// property name as variable
const name = "some Property";
const value = obj[name];

For that reason, array elements can only be accessed using bracket notation:

const value = arr[5]; // arr.5 would be a syntax error

// property name / index as variable
const x = 5;
const value = arr[x];

Wait... what about JSON?

JSON is a textual representation of data, just like XML, YAML, CSV, and others. To work with such data, it first has to be converted to JavaScript data types, i.e. arrays and objects (and how to work with those was just explained). How to parse JSON is explained in the question Parse JSON in JavaScript? .

Further reading material

How to access arrays and objects is fundamental JavaScript knowledge and therefore it is advisable to read the MDN JavaScript Guide, especially the sections

• Working with Objects
• Arrays
• Eloquent JavaScript - Data Structures

Accessing nested data structures

A nested data structure is an array or object which refers to other arrays or objects, i.e. its values are arrays or objects. Such structures can be accessed by consecutively applying dot or bracket notation.

Here is an example:

const data = {
    code: 42,
    items: [{
        id: 1,
        name: 'foo'
    }, {
        id: 2,
        name: 'bar'
    }]
};

Let's assume we want to access the name of the second item.

Here is how we can do it step-by-step:

As we can see data is an object, hence we can access its properties using dot notation. The items property is accessed as follows:

data.items

The value is an array, to access its second element, we have to use bracket notation:

data.items[1]

This value is an object and we use dot notation again to access the name property. So we eventually get:

const item_name = data.items[1].name;

Alternatively, we could have used bracket notation for any of the properties, especially if the name contained characters that would have made it invalid for dot notation usage:

const item_name = data['items'][1]['name'];

I'm trying to access a property but I get only undefined back?

Most of the time when you are getting undefined, the object/array simply doesn't have a property with that name.

const foo = {bar: {baz: 42}};
console.log(foo.baz); // undefined

Use console.log or console.dir and inspect the structure of object / array. The property you are trying to access might be actually defined on a nested object / array.

console.log(foo.bar.baz); // 42

What if the property names are dynamic and I don't know them beforehand?

If the property names are unknown or we want to access all properties of an object / elements of an array, we can use the for...in ^[MDN] loop for objects and the for ^[MDN] loop for arrays to iterate over all properties / elements.

Objects

To iterate over all properties of data, we can iterate over the object like so:

for (const prop in data) {
    // `prop` contains the name of each property, i.e. `'code'` or `'items'`
    // consequently, `data[prop]` refers to the value of each property, i.e.
    // either `42` or the array
}

Depending on where the object comes from (and what you want to do), you might have to test in each iteration whether the property is really a property of the object, or it is an inherited property. You can do this with Object#hasOwnProperty ^[MDN].

As alternative to for...in with hasOwnProperty, you can use Object.keys ^[MDN] to get an array of property names:

Object.keys(data).forEach(function(prop) {
  // `prop` is the property name
  // `data[prop]` is the property value
});

Arrays

To iterate over all elements of the data.items array, we use a for loop:

for(let i = 0, l = data.items.length; i < l; i++) {
    // `i` will take on the values `0`, `1`, `2`,..., i.e. in each iteration
    // we can access the next element in the array with `data.items[i]`, example:
    // 
    // var obj = data.items[i];
    // 
    // Since each element is an object (in our example),
    // we can now access the objects properties with `obj.id` and `obj.name`. 
    // We could also use `data.items[i].id`.
}

One could also use for...in to iterate over arrays, but there are reasons why this should be avoided: Why is 'for(var item in list)' with arrays considered bad practice in JavaScript?.

With the increasing browser support of ECMAScript 5, the array method forEach ^[MDN] becomes an interesting alternative as well:

data.items.forEach(function(value, index, array) {
    // The callback is executed for each element in the array.
    // `value` is the element itself (equivalent to `array[index]`)
    // `index` will be the index of the element in the array
    // `array` is a reference to the array itself (i.e. `data.items` in this case)
}); 

In environments supporting ES2015 (ES6), you can also use the for...of ^[MDN] loop, which not only works for arrays, but for any iterable:

for (const item of data.items) {
   // `item` is the array element, **not** the index
}

In each iteration, for...of directly gives us the next element of the iterable, there is no "index" to access or use.

What if the "depth" of the data structure is unknown to me?

In addition to unknown keys, the "depth" of the data structure (i.e. how many nested objects) it has, might be unknown as well. How to access deeply nested properties usually depends on the exact data structure.

But if the data structure contains repeating patterns, e.g. the representation of a binary tree, the solution typically includes to recursively ^[Wikipedia] access each level of the data structure.

Here is an example to get the first leaf node of a binary tree:

function getLeaf(node) {
    if (node.leftChild) {
        return getLeaf(node.leftChild); // <- recursive call
    }
    else if (node.rightChild) {
        return getLeaf(node.rightChild); // <- recursive call
    }
    else { // node must be a leaf node
        return node;
    }
}

const first_leaf = getLeaf(root);

const root = {_x000D_
    leftChild: {_x000D_
        leftChild: {_x000D_
            leftChild: null,_x000D_
            rightChild: null,_x000D_
            data: 42_x000D_
        },_x000D_
        rightChild: {_x000D_
            leftChild: null,_x000D_
            rightChild: null,_x000D_
            data: 5_x000D_
        }_x000D_
    },_x000D_
    rightChild: {_x000D_
        leftChild: {_x000D_
            leftChild: null,_x000D_
            rightChild: null,_x000D_
            data: 6_x000D_
        },_x000D_
        rightChild: {_x000D_
            leftChild: null,_x000D_
            rightChild: null,_x000D_
            data: 7_x000D_
        }_x000D_
    }_x000D_
};_x000D_
function getLeaf(node) {_x000D_
    if (node.leftChild) {_x000D_
        return getLeaf(node.leftChild);_x000D_
    } else if (node.rightChild) {_x000D_
        return getLeaf(node.rightChild);_x000D_
    } else { // node must be a leaf node_x000D_
        return node;_x000D_
    }_x000D_
}_x000D_
_x000D_
console.log(getLeaf(root).data);

A more generic way to access a nested data structure with unknown keys and depth is to test the type of the value and act accordingly.

Here is an example which adds all primitive values inside a nested data structure into an array (assuming it does not contain any functions). If we encounter an object (or array) we simply call toArray again on that value (recursive call).

function toArray(obj) {
    const result = [];
    for (const prop in obj) {
        const value = obj[prop];
        if (typeof value === 'object') {
            result.push(toArray(value)); // <- recursive call
        }
        else {
            result.push(value);
        }
    }
    return result;
}

const data = {_x000D_
  code: 42,_x000D_
  items: [{_x000D_
    id: 1,_x000D_
    name: 'foo'_x000D_
  }, {_x000D_
    id: 2,_x000D_
    name: 'bar'_x000D_
  }]_x000D_
};_x000D_
_x000D_
_x000D_
function toArray(obj) {_x000D_
  const result = [];_x000D_
  for (const prop in obj) {_x000D_
    const value = obj[prop];_x000D_
    if (typeof value === 'object') {_x000D_
      result.push(toArray(value));_x000D_
    } else {_x000D_
      result.push(value);_x000D_
    }_x000D_
  }_x000D_
  return result;_x000D_
}_x000D_
_x000D_
console.log(toArray(data));

Helpers

Since the structure of a complex object or array is not necessarily obvious, we can inspect the value at each step to decide how to move further. console.log ^[MDN] and console.dir ^[MDN] help us doing this. For example (output of the Chrome console):

> console.log(data.items)
 [ Object, Object ]

Here we see that that data.items is an array with two elements which are both objects. In Chrome console the objects can even be expanded and inspected immediately.

> console.log(data.items[1])
  Object
     id: 2
     name: "bar"
     __proto__: Object

This tells us that data.items[1] is an object, and after expanding it we see that it has three properties, id, name and __proto__. The latter is an internal property used for the prototype chain of the object. The prototype chain and inheritance is out of scope for this answer, though.

Try this :

$('.close-button').on('click', function(){
  $('.element').removeClass('grown');
  $('.element').addClass('spot');
});

$('.element').on('click', function(){
  $(this).removeClass('spot');
  $(this).addClass('grown');
});

I hope I understood your question.

One method that uses less math/theory is to sample 2, 5, 7, or 10 data points at a time and determine those which are outliers. A less accurate measure of an outlier than a Kalman Filter is to to use the following algorithm to take all pair wise distances between points and throw out the one that is furthest from the the others. Typically those values are replaced with the value closest to the outlying value you are replacing

For example

Smoothing at five sample points A, B, C, D, E

ATOTAL = SUM of distances AB AC AD AE

BTOTAL = SUM of distances AB BC BD BE

CTOTAL = SUM of distances AC BC CD CE

DTOTAL = SUM of distances DA DB DC DE

ETOTAL = SUM of distances EA EB EC DE

If BTOTAL is largest you would replace point B with D if BD = min { AB, BC, BD, BE }

This smoothing determines outliers and can be augmented by using the midpoint of BD instead of point D to smooth the positional line. Your mileage may vary and more mathematically rigorous solutions exist.

I resolved this by making sure my project shared the same .Net Framework version as the projects/libraries it depended on.

It turned out the libraries (projects within the solution) used .Net 4.6.1 and my project was using 4.5.2

Starting from Java 7 you can use try-with-resources Statement

try (BufferedReader br = new BufferedReader(new FileReader(path))) {
    return br.readLine();
}

Because the BufferedReader instance is declared in a try-with-resource statement, it will be closed regardless of whether the try statement completes normally or abruptly. So you don't need to close it yourself in the finally statement. (This is also the case with nested resource statements)

This is the recomanded way to work with resources, see the documentation for more detailed information

Short answer was provided here already: use <div [innerHTML]="yourHtml"> binding.

However the rest of the advices mentioned here might be misleading. Angular has a built-in sanitizing mechanism when you bind to properties like that. Since Angular is not a dedicated sanitizing library, it is overzealous towards suspicious content to not take any risks. For example, it sanitizes all SVG content into empty string.

You might hear advices to "sanitize" your content by using DomSanitizer to mark content as safe with bypassSecurityTrustXXX methods. There are also suggestions to use pipe to do that and that pipe is often called safeHtml.

All of this is misleading because it actually bypasses sanitizing, not sanitizing your content. This could be a security concern because if you ever do this on user provided content or on anything that you are not sure about — you open yourself up for a malicious code attacks.

If Angular removes something that you need by its built-in sanitization — what you can do instead of disabling it is delegate actual sanitization to a dedicated library that is good at that task. For example — DOMPurify.

I've made a wrapper library for it so it could be easily used with Angular: https://github.com/TinkoffCreditSystems/ng-dompurify

It also has a pipe to declaratively sanitize HTML:

<div [innerHtml]="value | dompurify"></div>

The difference to pipes suggested here is that it actually does do the sanitization through DOMPurify and therefore work for SVG.

One thing to keep in mind is DOMPurify is great for sanitizing HTML/SVG, but not CSS. So you can provider Angular's CSS sanitizer to handle CSS:

import {NgModule, ?_sanitizeStyle} from '@angular/core';
import {SANITIZE_STYLE} from '@tinkoff/ng-dompurify';

@NgModule({
    // ...
    providers: [
        {
            provide: SANITIZE_STYLE,
            useValue: ?_sanitizeStyle,
        },
    ],
    // ...
})
export class AppModule {}

It's internal — hense ? prefix, but this is how Angular team use it across their own packages as well anyway. That library also works for Angular Universal and server side renedring environment.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

result = soup.find('strong', text='text I am looking for').text

The function argument to setTimeout is closing over the loop variable. The loop finishes before the first timeout and displays the current value of i, which is 3.

Because JavaScript variables only have function scope, the solution is to pass the loop variable to a function that sets the timeout. You can declare and call such a function like this:

for (var i = 1; i <= 2; i++) {
    (function (x) {
        setTimeout(function () { alert(x); }, 100);
    })(i);
}

public static int[] strArrayToIntArray(String[] a){
    int[] b = new int[a.length];
    for (int i = 0; i < a.length; i++) {
        b[i] = Integer.parseInt(a[i]);
    }

    return b;
}

This is a simple function, that should help you. You can use him like this:

int[] arr = strArrayToIntArray(/*YOUR STR ARRAY*/);

Just pass the object as is. Note you can create the object as follows

var data0 = {numberId: "1", companyId : "531"};

$.ajax({
 type: "POST",
 url: "TelephoneNumbers.aspx/DeleteNumber",
 data: dataO,
 contentType: "application/json; charset=utf-8",
 dataType: "json",
 success: function(msg) {
 alert('In Ajax');
 }
});

UPDATE seems an odd issue with the serializer, maybe it is expecting a string, out of interest can you try the following.

data: "{'numberId':'1', 'companyId ':'531'}",

I've written a simple wrapper around git-checkout-index that you can use like this:

git export ~/the/destination/dir

If the destination directory already exists, you'll need to add -f or --force.

Installation is simple; just drop the script somewhere in your PATH, and make sure it's executable.

"I have been under the impression for that JavaScript was always asynchronous"

You can use JavaScript in a synchronous way, or an asynchronous way. In fact JavaScript has really good asynchronous support. For example I might have code that requires a database request. I can then run other code, not dependent on that request, while I wait for that request to complete. This asynchronous coding is supported with promises, async/await, etc. But if you don't need a nice way to handle long waits then just use JS synchronously.

What do we mean by 'asynchronous'. Well it does not mean multi-threaded, but rather describes a non-dependent relationship. Check out this image from this popular answer:

         A-Start ------------------------------------------ A-End   
           | B-Start -----------------------------------------|--- B-End   
           |    |      C-Start ------------------- C-End      |      |   
           |    |       |                           |         |      |
           V    V       V                           V         V      V      
1 thread->|<-A-|<--B---|<-C-|-A-|-C-|--A--|-B-|--C-->|---A---->|--B-->| 

We see that a single threaded application can have async behavior. The work in function A is not dependent on function B completing, and so while function A began before function B, function A is able to complete at a later time and on the same thread.

So, just because JavaScript executes one command at a time, on a single thread, it does not then follow that JavaScript can only be used as a synchronous language.

"Is there a good reference anywhere about when it will be synchronous and when it will be asynchronous"

I'm wondering if this is the heart of your question. I take it that you mean how do you know if some code you are calling is async or sync. That is, will the rest of your code run off and do something while you wait for some result? Your first check should be the documentation for whichever library you are using. Node methods, for example, have clear names like readFileSync. If the documentation is no good there is a lot of help here on SO. EG:

How to know if a function is async?

Exception code 0xc0000005 is an Access Violation. An AV at fault offset 0x00000000 means that something in your service's code is accessing a nil pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.

The easiest way is probably just to split on your target word

my_string="hello python world , i'm a beginner "
print my_string.split("world",1)[1] 

split takes the word(or character) to split on and optionally a limit to the number of splits.

In this example split on "world" and limit it to only one split.

I also had this problem. I think there is a bug in the way Flutter caches images. My guess is that when you first attempted to load pizza0.png, it wasn't available, and Flutter has cached this failed result. Then, even after adding the correct image, Flutter still assumes it isn't available.

This is all guess-work, based on the fact that I had the same problem, and calling this once on app start fixed the problem for me:

imageCache.clear();

This clears the image cache, meaning that Flutter will then attempt to load the images fresh rather than search the cache.

PS I've also found that you need to call this whenever you change any existing images, for the same reason - Flutter will load the old cached version. The alternative is to rename the image.

if (intent.resolveActivity(getPackageManager()) == null) {
    Utils.showToast(activity, no_app_available_to_complete_this_task);
} else {
    startActivityForResult(intent, 1);
}

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

Does this work?

Workbooks.Open Filename:=filepath, ReadOnly:=True

Or, as pointed out in a comment, to keep a reference to the opened workbook:

Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)

I have created this type that allows me to easily override nested interfaces:

export type DeepPartialAny<T> = {
  [P in keyof T]?: T[P] extends Obj ? DeepPartialAny<T[P]> : any;
};

export type Override<A extends Obj, AOverride extends DeepPartialAny<A>> = { [K in keyof A]:
  AOverride[K] extends never
    ? A[K]
    : AOverride[K] extends Obj
    ? Override<A[K], AOverride[K]>
    : AOverride[K]
};

And then you can use it like that:

interface Foo {
  Bar: {
    Baz: string;
  };
}
type Foo2 = Override<Foo, { Bar: { Baz: number } }>;

const bar: Foo2['Bar']['Baz'] = 1; // number;

Take a look at Phil Haack's post on model binding JSON data. The problem is that the default model binder doesn't serialize JSON properly. You need some sort of ValueProvider OR you could write a custom model binder:

using System.IO;
using System.Web.Script.Serialization;

public class JsonModelBinder : DefaultModelBinder {
        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) {
            if(!IsJSONRequest(controllerContext)) {
                return base.BindModel(controllerContext, bindingContext);
            }

            // Get the JSON data that's been posted
            var request = controllerContext.HttpContext.Request;
            //in some setups there is something that already reads the input stream if content type = 'application/json', so seek to the begining
            request.InputStream.Seek(0, SeekOrigin.Begin);
            var jsonStringData = new StreamReader(request.InputStream).ReadToEnd();

            // Use the built-in serializer to do the work for us
            return new JavaScriptSerializer()
                .Deserialize(jsonStringData, bindingContext.ModelMetadata.ModelType);

            // -- REQUIRES .NET4
            // If you want to use the .NET4 version of this, change the target framework and uncomment the line below
            // and comment out the above return statement
            //return new JavaScriptSerializer().Deserialize(jsonStringData, bindingContext.ModelMetadata.ModelType);
        }

        private static bool IsJSONRequest(ControllerContext controllerContext) {
            var contentType = controllerContext.HttpContext.Request.ContentType;
            return contentType.Contains("application/json");
        }
    }

public static class JavaScriptSerializerExt {
        public static object Deserialize(this JavaScriptSerializer serializer, string input, Type objType) {
            var deserializerMethod = serializer.GetType().GetMethod("Deserialize", BindingFlags.NonPublic | BindingFlags.Static);

            // internal static method to do the work for us
            //Deserialize(this, input, null, this.RecursionLimit);

            return deserializerMethod.Invoke(serializer,
                new object[] { serializer, input, objType, serializer.RecursionLimit });
        }
    }

And tell MVC to use it in your Global.asax file:

ModelBinders.Binders.DefaultBinder = new JsonModelBinder();

Also, this code makes use of the content type = 'application/json' so make sure you set that in jquery like so:

$.ajax({
    dataType: "json",
    contentType: "application/json",            
    type: 'POST',
    url: '/Controller/Action',
    data: { 'items': JSON.stringify(lineItems), 'id': documentId }
});

For unix systems only:

>>> import datetime
>>> d = datetime.date(2011,01,01)
>>> d.strftime("%s")  # <-- THIS IS THE CODE YOU WANT
'1293832800'

Note 1: dizzyf observed that this applies localized timezones. Don't use in production.

Note 2: Jakub Narebski noted that this ignores timezone information even for offset-aware datetime (tested for Python 2.7).

Solution works very well,

public List<String> savePerson(@RequestBody Person[] personArray)  

For this signature you can pass Person array from postman like

[
{
  "empId": "10001",
  "tier": "Single",
  "someting": 6,
  "anything": 0,
  "frequency": "Quaterly"
}, {
  "empId": "10001",
  "tier": "Single",
  "someting": 6,
  "anything": 0,
  "frequency": "Quaterly"
}

Don't forget to add consumes tag:

@RequestMapping(value = "/getEmployeeList", method = RequestMethod.POST, consumes="application/json", produces = "application/json")
public List<Employee> getEmployeeDataList(@RequestBody Employee[] employeearray) { ... }

You can call a function on click event of button.

<input type="button" class="btn btn-info" value="Input Button" onclick=" relocate_home()">

<script>
function relocate_home()
{
     location.href = "www.yoursite.com";
} 
</script>

OR Use this Code

<a href="#link" class="btn btn-info" role="button">Link Button</a>

For information i removed the action attribute and i got this error when i call an ajax post..Even though my action attribute in the form looks like this action="javascript://;"

I thought I had it from the ajax call and serializing the form but I added the dummy action attribute to the form back again and it worked.

Add a border to the regular item, the same color as the background, so that it cannot be seen. That way the item has a border: 1px whether it is being hovered or not.

You can make use of the plusMonths and minusDays methods in Java 8:

// Parse your date into a LocalDate
LocalDate parsed = LocalDate.parse("1/13/2012", DateTimeFormatter.ofPattern("M/d/yyyy"));

// We only care about its year and month, set the date to first date of that month
LocalDate localDate = LocalDate.of(parsed.getYear(), parsed.getMonth(), 1);

// Add one month, subtract one day 
System.out.println(localDate.plusMonths(1).minusDays(1)); // 2012-01-31

The virtual keyword is used to modify a method, property, indexer, or event declaration and allow for it to be overridden in a derived class. For example, this method can be overridden by any class that inherits it:

public virtual double Area() 
{
    return x * y;
}

You cannot use the virtual modifier with the static, abstract, private, or override modifiers. The following example shows a virtual property:

class MyBaseClass
{
    // virtual auto-implemented property. Overrides can only
    // provide specialized behavior if they implement get and set accessors.
    public virtual string Name { get; set; }

    // ordinary virtual property with backing field
    private int num;
    public virtual int Number
    {
        get { return num; }
        set { num = value; }
    }
}


class MyDerivedClass : MyBaseClass
{
    private string name;

    // Override auto-implemented property with ordinary property
    // to provide specialized accessor behavior.
    public override string Name
    {
        get
        {
            return name;
        }
        set
        {
            if (value != String.Empty)
            {
                name = value;
            }
            else
            {
                name = "Unknown";
            }
        }
    }
}

the ctrl alt f9 , is the temporary solution , going to options-formula-auto calculate is the right way, that option turned manual, because some shortcut key on being pressed by mistake turns automatic to manual

If you are a Windows user, this is a common error when you use XAMPP since LDAP is not enabled by default.

You can follow this steps to make sure LDAP works in your XAMPP:

• [Your Drive]:\xampp\php\php.ini: In this file uncomment the following line:

   extension=php_ldap.dll
  

• Move the file: libsasl.dll, from [Your Drive]:\xampp\php to [Your Drive]:\xampp\apache\bin (Note: moving the file is needed only for XAMPP prior to version: 5.6.28)

• Restart Apache.

• You can now use functions of the LDAP Module!

If you use Linux:

For php5:

sudo apt-get install php5-ldap

For php7:

sudo apt-get install php7.0-ldap

If you are using the latest version of PHP you can do

sudo apt-get install php-ldap

running the above command should do the trick.

if for any reason it doesn't work check your php.ini configuration to enable ldap, remove the semicolon before extension=ldap to uncomment, save and restart Apache

A much simpler way to do this is to use vCenter Converter Standalone Client and do a P2V but in this case a V2V. It is much faster than copying the entire VM files onto some storage somewhere and copy it onto your new vCenter. It takes a long time to copy or exporting it to an OVF template and then import it. You can set your vCenter Converter Standalone Client to V2V in one step and synchronize and then have it power up the VM on the new Vcenter and shut off on the old vCenter. Simple.

For me using this method I was able to move a VM from one vCenter to another vCenter in about 30 minutes as compared to copying or exporting which took over 2hrs. Your results may vary.

This process below, from another responder, would work even better if you can present that datastore to ESXi servers on the vCenter and then follow step 2. Eliminating having to copy all the VMs then follow rest of the process.

1. Copy all of the cloned VM's files from its directory, and place it on its destination datastore.
2. In the VI client connected to the destination vCenter, go to the Inventory->Datastores view.
3. Open the datastore browser for the datastore where you placed the VM's files.
4. Find the .vmx file that you copied over and right-click it.
5. Choose 'Register Virtual Machine', and follow whatever prompts ensue. (Depending on your version of vCenter, this may be 'Add to Inventory' or some other variant)

Try placing the host name (db01.mysql.vm.MyHostingServer.net) in your windows host (C:\windows\system32\drivers\etc\host) file along with it's IP address and port number and see if that helps.

It should be possible like this (or use jQuery like $('meta[name=author]').attr("content");):

<html>
<head>
<title>Meta Data</title>
<meta name="Author" content="Martin Webb">
<meta name="Author" content="A.N. Other">
<meta name="Description" content="A sample html file for extracting meta data">
<meta name="Keywords" content="JavaScript, DOM, W3C">

</head>

<body>
<script language="JavaScript"><!--
if (document.getElementsByName) {
  var metaArray = document.getElementsByName('Author');
  for (var i=0; i<metaArray.length; i++) {
    document.write(metaArray[i].content + '<br>');
  }

  var metaArray = document.getElementsByName('Description');
  for (var i=0; i<metaArray.length; i++) {
    document.write(metaArray[i].content + '<br>');
  }

  var metaArray = document.getElementsByName('Keywords');
  for (var i=0; i<metaArray.length; i++) {
    document.write(metaArray[i].content + '<br>');
  }
}
//--></script>
</body>

</html>

Html.TextBoxFor(model => model.Control.PeriodType, 
    new { @class="text-box single-line"})

you can use like this ; same output with Html.EditorFor ,and you can add your html attributes

Here is a regex_subst() function. Examples:

=regex_subst("watermellon", "[aeiou]", "")
---> wtrmlln
=regex_subst("watermellon", "[^aeiou]", "")
---> aeeo

Here is the simplified code (simpler for me, anyway). I couldn't figure out how to build a suitable output pattern using the above to work like my examples:

Function regex_subst( _
     strInput As String _
   , matchPattern As String _
   , Optional ByVal replacePattern As String = "" _
) As Variant
    Dim inputRegexObj As New VBScript_RegExp_55.RegExp

    With inputRegexObj
        .Global = True
        .MultiLine = True
        .IgnoreCase = False
        .Pattern = matchPattern
    End With

    regex_subst = inputRegexObj.Replace(strInput, replacePattern)
End Function

For sake of completeness (as I can't add comments yet), let me also add this detail as another answer:

(Edit: To be read after realizing that the source data (i.e. in the OP's case, database result set) could be the problem (by returning numeric columns as strings), and json_encode() in fact was not the source of the problem)

Manual pages of both "mysql_fetch_array":

Returns an array of strings that corresponds to the fetched row,

... and "mysql_ fetch_ row":

Returns an numerical array of strings that corresponds to the fetched row

clearly states that; the entries in the returned array will be strings.

(I was using the DB class in phpBB2 (yes I know, it's obsolete!), and "sql_fetchrow()" method of that class uses "mysql_fetch_array()")

Not realizing that, I also ended up finding this question, and understanding the problem! :)

As Pascal Martin stated above in his follow-up comments, I believe a solution that takes care of the "incorrect type" problem at the source (i.e. by using the "mysql_field_type()" function and doing the casting right after fetch, (or other fetch methods like "object"?)) would be the better in general.

No, you can specify the list as a keyword argument to your function.

alist = []
def fn(alist=alist):
    alist.append(1)
fn()
print alist    # [1]

I'd say it's bad practice though. Kind of too hackish. If you really need to use a globally available singleton-like data structure, I'd use the module level variable approach, i.e. put 'alist' in a module and then in your other modules import that variable:

In file foomodule.py:

alist = []

In file barmodule.py:

import foomodule
def fn():
    foomodule.alist.append(1)
print foomodule.alist    # [1]

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload
[default] Attempting graceful shutdown of VM...
[default] Setting the name of the VM...

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

You should use a delegate type and specify that as your command parameter. You could use one of the built in delegate types - Action and Func.

In your case, it looks like your delegate takes two parameters, and returns a result, so you could use Func:

List<IJob> GetJobs(Func<FullTimeJob, Student, FullTimeJob> projection)

You could then call your GetJobs method passing in a delegate instance. This could be a method which matches that signature, an anonymous delegate, or a lambda expression.

P.S. You should use PascalCase for method names - GetJobs, not getJobs.

 <StyledInput text="NAME" imgUri={require('../assets/userIcon.png')} ></StyledInput>

in my case i tried so much but finally it work StyledInput component name image inside the StyledInput if you still not understand let me know

This is just a warning and it doesn't make problem for your project to run, you can just ignore it and continue coding. But if you're obsessed about clean coding, same as me, you have two options:

1. Hover the mouse on warning in VS Code or any IDE and use quick fix to remove white spaces.
2. Press f1 then type trim trailing whitespace.

No, a null check is not needed before using instanceof.

The expression x instanceof SomeClass is false if x is null.

From the Java Language Specification, section 15.20.2, "Type comparison operator instanceof":

"At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false."

So if the operand is null, the result is false.

The guy above gave comparison for HashMap / HashSet vs. TreeMap / TreeSet.

I will talk about ArrayList vs. LinkedList:

ArrayList:

• O(1) get()
• amortized O(1) add()
• if you insert or delete an element in the middle using ListIterator.add() or Iterator.remove(), it will be O(n) to shift all the following elements

LinkedList:

• O(n) get()
• O(1) add()
• if you insert or delete an element in the middle using ListIterator.add() or Iterator.remove(), it will be O(1)

Do you really need to "build" it from javascript or can you simply return the built HTML from PHP and insert it into the DOM?

1. Send AJAX request to php script
2. PHP script processes request and builds table
3. PHP script sends response back to JS in form of encoded HTML
4. JS takes response and inserts it into the DOM

Android supports the dd command.

dd if=/path/file of=/path/file

For Mac users

I found out one more way: You can check if /usr/local/var/run/nginx.pid exists. If it is - nginx is running. Useful way for scripting.

Example:

if [ -f /usr/local/var/run/nginx.pid ]; then
   echo "Nginx is running"

fi

You most likely just need to format your integer:

'%0*d' % (fill, your_int)

For example,

>>> '%0*d' % (3, 4)
'004'

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

Just putting it in src/main/resources will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties file inside it, losing its initial point of making logging configurable.

I usually put it in src/main/resources, and set it to be output to target like so:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <targetPath>${project.build.directory}</targetPath>
            <includes>
                <include>log4j.properties</include>
            </includes>
        </resource>
    </resources>
</build>

Additionally, in order for log4j to actually see it, you have to add the output directory to the class path. If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path manifest entry like so:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>com.your-package.Main</mainClass>
            </manifest>
            <manifestEntries>
                <Class-Path>.</Class-Path>
            </manifestEntries>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- bind to the packaging phase -->
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Now the log4j.properties file will be right next to your JAR file, independently configurable.

To run your application directly from Eclipse, add the resources directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New select the Classpath tab, select Advanced and browse to your src/resources directory.

I had same problem, for me npm install request --save solved the problem. Hope it helps.

If you have a form as such:

<form id="myform">
...
</form>

You can use the following jQuery code to do something before the form is submitted:

$('#myform').submit(function() {
    // DO STUFF...
    return true; // return false to cancel form action
});

I overcome this issue with if anybody interested. In myMain method i called my readasync method like

Dispatcher.BeginInvoke(new ThreadStart(() => ReadData()));

Everything is fine for me now.

Wonderful answer! I needed to fill in the empty cells in a column where there were titles in cells that applied to the empty cells below until the next title cell.

I used your code above to develop the code that is below my example sheet here. I applied this code as a macro ctl/shft/D to rapidly run down the column copying the titles.

--- Example Spreadsheet ------------ Title1 is copied to rows 2 and 3; Title2 is copied to cells below it in rows 5 and 6. After the second run of the Macro the active cell is the Title3 cell.

 ' **row** **Column1**        **Column2**
 '    1     Title1         Data 1 for title 1
 '    2                    Data 2 for title 1
 '    3                    Data 3 for title 1
 '    4     Title2         Data 1 for title 2
 '    5                    Data 2 for title 2
 '    6                    Data 3 for title 2
 '    7   Title 3          Data 1 for title 3

----- CopyDown code ----------

Sub CopyDown()
Dim Lastrow As String, FirstRow As String, strtCell As Range
'
' CopyDown Macro
' Copies the current cell to any empty cells below it.   
'
' Keyboard Shortcut: Ctrl+Shift+D

I ran into the same problem and was able to resolve it in very powerful way that allows unlimited sorting possibilities.

I created a View using (saving) 2 sort orders (*explanation on how to do so below).

After that I simply applied the update queries to the View created and it worked great.

Here are the 2 queries I used on the view:

1st Query:

Update  MyView
Set SortID=0

2nd Query:

DECLARE @sortID int
SET     @sortID = 0
UPDATE  MyView
SET     @sortID = sortID = @sortID + 1

*To be able to save the sorting on the View I put TOP into the SELECT statement. This very useful workaround allows the View results to be returned sorted as set when the View was created when the View is opened. In my case it looked like:

(NOTE: Using this workaround will place an big load on the server if using a large table and it is therefore recommended to include as few fields as possible in the view if working with large tables)

SELECT     TOP (600000) 
dbo.Items.ID, dbo.Items.Code, dbo.Items.SortID, dbo.Supplier.Date, 
dbo.Supplier.Code AS Expr1
FROM         dbo.Items INNER JOIN
                      dbo.Supplier ON dbo.Items.SupplierCode = dbo.Supplier.Code
ORDER BY dbo.Supplier.Date, dbo.Items.ID DESC

SASS modules version

Soon, using @import in sass will be depreciated. SASS modules configuration works using @use instead.

@use "../node_modules/font-awesome/scss/font-awesome"  with (
  $fa-font-path: "../icons"
);

.icon-user {
  @extend .fa;
  @extend .fa-user;
}

In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.

The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct/union/enum) and ordinary identifiers (for typedef and other identifiers).

If you just said:

struct Foo { ... };
Foo x;

you would get a compiler error, because Foo is only defined in the tag namespace.

You'd have to declare it as:

struct Foo x;

Any time you want to refer to a Foo, you'd always have to call it a struct Foo. This gets annoying fast, so you can add a typedef:

struct Foo { ... };
typedef struct Foo Foo;

Now struct Foo (in the tag namespace) and just plain Foo (in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo without the struct keyword.

The construct:

typedef struct Foo { ... } Foo;

is just an abbreviation for the declaration and typedef.

Finally,

typedef struct { ... } Foo;

declares an anonymous structure and creates a typedef for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.

In C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.

You can use:

System.Text.Encoding.ASCII.GetString(buf);

But sometimes you will get a weird number instead of the string you want. In that case, your original string may have some hexadecimal character when you see it. If it's the case, you may want to try this:

System.Text.Encoding.UTF8.GetString(buf);

Or as a last resort:

System.Text.Encoding.Default.GetString(bytearray);

By using a div with style z-index:1; and position: absolute; you can overlay your div on any other div.

z-index determines the order in which divs 'stack'. A div with a higher z-index will appear in front of a div with a lower z-index. Note that this property only works with positioned elements.

I was facing the same issue in my Angular application. I was using RocketChat REST API in my application and I was trying to use the rooms.createDiscussion, but as an error as below.

ERROR Error: Uncaught (in promise): HttpErrorResponse: {"headers":{"normalizedNames":{},"lazyUpdate":null},"status":200,"statusText":"OK","url":"myurl/rocketchat/api/v1/rooms.createDiscussion","ok":false,"name":"HttpErrorResponse","message":"Http failure during parsing for myrul/rocketchat/api/v1/rooms.createDiscussion","error":{"error":{},"text":"

I have tried couple of things like changing the responseType: 'text' but none of them worked. At the end I was able to find the issue was with my RocketChat installation. As mentioned in the RocketChat change log the API rooms.createDiscussion is been introduced in the version 1.0.0 unfortunately I was using a lower version.

My suggestion is to check the REST API is working fine or not before you spend time to fix the error in your Angular code. I used curl command to check that.

curl -H "X-Auth-Token: token" -H "X-User-Id: userid" -H "Content-Type: application/json" myurl/rocketchat/api/v1/rooms.createDiscussion -d '{ "prid": "GENERAL", "t_name": "Discussion Name"}'

There as well I was getting an invalid HTML as a response.

<!DOCTYPE html>
<html>
<head>
<meta name="referrer" content="origin-when-crossorigin">
<script>/* eslint-disable */

'use strict';
(function() {
        var debounce = function debounce(func, wait, immediate) {

Instead of a valid JSON response as follows.

{
    "discussion": {
        "rid": "cgk88DHLHexwMaFWh",
        "name": "WJNEAM7W45wRYitHo",
        "fname": "Discussion Name",
        "t": "p",
        "msgs": 0,
        "usersCount": 0,
        "u": {
            "_id": "rocketchat.internal.admin.test",
            "username": "rocketchat.internal.admin.test"
        },
        "topic": "general",
        "prid": "GENERAL",
        "ts": "2019-04-03T01:35:32.271Z",
        "ro": false,
        "sysMes": true,
        "default": false,
        "_updatedAt": "2019-04-03T01:35:32.280Z",
        "_id": "cgk88DHLHexwMaFWh"
    },
    "success": true
}

So after updating to the latest RocketChat I was able to use the mentioned REST API.

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

You asked about typical uses.

One common complaint about shell scripting is that you (allegedly) can't pass by reference to get values back out of functions.

But actually, via "eval", you can pass by reference. The callee can pass back a list of variable assignments to be evaluated by the caller. It is pass by reference because the caller can allowed to specify the name(s) of the result variable(s) - see example below. Error results can be passed back standard names like errno and errstr.

Here is an example of passing by reference in bash:

#!/bin/bash
isint()
{
    re='^[-]?[0-9]+$'
    [[ $1 =~ $re ]]
}

#args 1: name of result variable, 2: first addend, 3: second addend 
iadd()
{
    if isint ${2} && isint ${3} ; then
        echo "$1=$((${2}+${3}));errno=0"
        return 0
    else
        echo "errstr=\"Error: non-integer argument to iadd $*\" ; errno=329"
        return 1
    fi
}

var=1
echo "[1] var=$var"

eval $(iadd var A B)
if [[ $errno -ne 0 ]]; then
    echo "errstr=$errstr"
    echo "errno=$errno"
fi
echo "[2] var=$var (unchanged after error)"

eval $(iadd var $var 1)
if [[ $errno -ne 0 ]]; then
    echo "errstr=$errstr"
    echo "errno=$errno"
fi  
echo "[3] var=$var (successfully changed)"

The output looks like this:

[1] var=1
errstr=Error: non-integer argument to iadd var A B
errno=329
[2] var=1 (unchanged after error)
[3] var=2 (successfully changed)

There is almost unlimited band width in that text output! And there are more possibilities if the multiple output lines are used: e.g., the first line could be used for variable assignments, the second for continuous 'stream of thought', but that's beyond the scope of this post.

Solution if literals are involved.

I am using Pentaho Data Integration and dont get to specify the sql syntax. Using a very simple DB lookup gave the error "Illegal mix of collations (cp850_general_ci,COERCIBLE) and (latin1_swedish_ci,COERCIBLE) for operation '='"

The generated code was "SELECT DATA_DATE AS latest_DATA_DATE FROM hr_cc_normalised_data_date_v WHERE PSEUDO_KEY = ?"

Cutting the story short the lookup was to a view and when I issued

mysql> show full columns from hr_cc_normalised_data_date_v;
+------------+------------+-------------------+------+-----+
| Field      | Type       | Collation         | Null | Key |
+------------+------------+-------------------+------+-----+
| PSEUDO_KEY | varchar(1) | cp850_general_ci  | NO   |     |
| DATA_DATE  | varchar(8) | latin1_general_cs | YES  |     |
+------------+------------+-------------------+------+-----+

which explains where the 'cp850_general_ci' comes from.

The view was simply created with 'SELECT 'X',......' According to the manual literals like this should inherit their character set and collation from server settings which were correctly defined as 'latin1' and 'latin1_general_cs' as this clearly did not happen I forced it in the creation of the view

CREATE OR REPLACE VIEW hr_cc_normalised_data_date_v AS
SELECT convert('X' using latin1) COLLATE latin1_general_cs        AS PSEUDO_KEY
    ,  DATA_DATE
FROM HR_COSTCENTRE_NORMALISED_mV
LIMIT 1;

now it shows latin1_general_cs for both columns and the error has gone away. :)

There are good answers here but If you like to have some interface for postgres database management, you can install pgAdmin on your local computer and connect to the remote machine using its IP and the postgres exposed port (by default 5432).

If you have a program that models cars you have a class to represent cars, so in Code you could say:

Car someCar = new Car();

someCar is now an instance of the class Car. If the program is used at a repairshop and the someCar represents your car in their system, then your car is the object.

So Car is a class that can represent any real world car someCar is an instance of the Car class and someCare represents one real life object (your car)

however instance and object is very often used interchangably when it comes to discussing coding

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

Here is a way to remove non-interactively a specific <commit-id>, knowing only the <commit-id> you would like to remove:

git rebase --onto <commit-id>^ <commit-id> HEAD

you must chmod and chown the new folder

chown -R redis and chmod ...

bool isPowerOfTwo(int x_)
{
  register int bitpos, bitpos2;
  asm ("bsrl %1,%0": "+r" (bitpos):"rm" (x_));
  asm ("bsfl %1,%0": "+r" (bitpos2):"rm" (x_));
  return bitpos > 0 && bitpos == bitpos2;
}

1 - You can use the same activity as both dialog and full screen, dynamically:

Call setTheme(android.R.style.Theme_Dialog) before calling setContentView(...) and super.oncreate() in your Activity.

2 - If you don't plan to change the activity theme style you can use

<activity android:theme="@android:style/Theme.Dialog" />

(as mentioned by @faisal khan)

Of the top of my head, can you try to use the 'q' operator for the string literal

something like

insert all
  into domo_queries values (q'[select 
substr(to_char(max_data),1,4) as year,
substr(to_char(max_data),5,6) as month,
max_data
from dss_fin_user.acq_dashboard_src_load_success
where source = 'CHQ PeopleSoft FS']')
select * from dual;

Note that the single quotes of your predicate are not escaped, and the string sits between q'[...]'.

With a vector iterators do no offer any real advantage. The syntax is uglier, longer to type and harder to read.

Iterating over a vector using iterators is not faster and is not safer (actually if the vector is possibly resized during the iteration using iterators will put you in big troubles).

The idea of having a generic loop that works when you will change later the container type is also mostly nonsense in real cases. Unfortunately the dark side of a strictly typed language without serious typing inference (a bit better now with C++11, however) is that you need to say what is the type of everything at each step. If you change your mind later you will still need to go around and change everything. Moreover different containers have very different trade-offs and changing container type is not something that happens that often.

The only case in which iteration should be kept if possible generic is when writing template code, but that (I hope for you) is not the most frequent case.

The only problem present in your explicit index loop is that size returns an unsigned value (a design bug of C++) and comparison between signed and unsigned is dangerous and surprising, so better avoided. If you use a decent compiler with warnings enabled there should be a diagnostic on that.

Note that the solution is not to use an unsiged as the index, because arithmetic between unsigned values is also apparently illogical (it's modulo arithmetic, and x-1 may be bigger than x). You instead should cast the size to an integer before using it. It may make some sense to use unsigned sizes and indexes (paying a LOT of attention to every expression you write) only if you're working on a 16 bit C++ implementation (16 bit was the reason for having unsigned values in sizes).

As a typical mistake that unsigned size may introduce consider:

void drawPolyline(const std::vector<P2d>& points)
{
    for (int i=0; i<points.size()-1; i++)
        drawLine(points[i], points[i+1]);
}

Here the bug is present because if you pass an empty points vector the value points.size()-1 will be a huge positive number, making you looping into a segfault. A working solution could be

for (int i=1; i<points.size(); i++)
    drawLine(points[i - 1], points[i]);

but I personally prefer to always remove unsinged-ness with int(v.size()).

PS: If you really don't want to think by to yourself to the implications and simply want an expert to tell you then consider that a quite a few world recognized C++ experts agree and expressed opinions on that unsigned values are a bad idea except for bit manipulations.

Discovering the ugliness of using iterators in the case of iterating up to second-last is left as an exercise for the reader.

Even if fileno(FILE *) may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.

To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)

You can make a default constraint on this column that will put a default getdate() as a value.

Example:

alter table dbo.TABLE 
add constraint df_TABLE_DATE default getdate() for DATE_COLUMN

Since data.table 1.12.4 (Oct 2019), data.table gains two functions to facilitate this: nafill and setnafill.

nafill operates on columns:

cols = c('a', 'b')
y[ , (cols) := lapply(.SD, nafill, fill=0), .SDcols = cols]

setnafill operates on tables (the replacements happen by-reference/in-place)

setnafill(y, cols=cols, fill=0)
# print y to show the effect
y[]

This will also be more efficient than the other options; see ?nafill for more, the last-observation-carried-forward (LOCF) and next-observation-carried-backward (NOCB) versions of NA imputation for time series.

This will work for your data.table version:

for (col in c("a", "b")) y[is.na(get(col)), (col) := 0]

Alternatively, as David Arenburg points out below, you can use set (side benefit - you can use it either on data.frame or data.table):

for (col in 1:2) set(x, which(is.na(x[[col]])), col, 0)

I deployed Facebook Android SDK to Sonatype repository.

You can include this library as Gradle dependency:

repositories {
    maven {
        url 'https://oss.sonatype.org/content/groups/public'
    }
}

dependencies {
    compile 'com.shamanland:facebook-android-sdk:3.15.0-SNAPSHOT'
}

Original post here.

You can include any layout file in other layout file as-

             <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="10dp"
                android:layout_marginRight="30dp" >

                <include
                    android:id="@+id/frnd_img_file"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    layout="@layout/include_imagefile"/>

                <include
                    android:id="@+id/frnd_video_file"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    layout="@layout/include_video_lay" />

                <ImageView
                    android:id="@+id/downloadbtn"
                    android:layout_width="30dp"
                    android:layout_height="30dp"
                    android:layout_centerInParent="true"
                    android:src="@drawable/plus"/>
            </RelativeLayout>

here the layout files in include tag are other .xml layout files in the same res folder.

select top 0 *
into #mytemptable

you must use new version of Management Studio. And also you will got an error 29506. so you should run as Administrator for setup. Look this site. http://shareis.com/post/29506-management-studio-express

String interpolation is going to be included with Python 3.6 as specified in PEP 498. You will be able to do this:

name = 'Spongebob Squarepants'
print(f'Who lives in a Pineapple under the sea? \n{name}')

Note that I hate Spongebob, so writing this was slightly painful. :)

I had similar issue. What worked for me is that I had added wrong Class Library from visual studio. I added by using the search feature of visual studio.

What I needed to do was Add New Project > Visual C# > Class Library. And this newly added class library is the right one and can now be added as reference to any project.

I'm following these steps and it's been working so far:

1. Copy and paste the folder as used to.
2. Open Android Studio (v3.0.1).
3. Select Open an existing Project.
4. Close the message that will pop up with title: "Import Gradle Projects".
5. At left side on Android Tab go to: app -> java -> select the first folder (your project folder)
6. Refactor => Rename... (Shift + F6)
7. Rename Package, Select both options - Put the new folder's name in lowercase.
8. Do Refactor
9. Select: Sync Project with Gradle Files at toolbar.
10. Build => Clean Project
11. Go to app -> res -> values -> strings.xml, and change the app name at 2nd line.

This works perfectly:

public boolean deleteSingleRow(String rowId) 
{
    return db.delete(DATABASE_TABLE, KEY_ROWID + "=" + rowId, null) > 0;
}

You can also refer to this example.

This worked for me:

let wrapped = mount(<Component />);
expect(wrapped.find("input").get(0).props.value).toEqual("something");

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

The importance of locales is that your environment/os can provide formatting functionality for all installed locales even if you don't know about them when you write your application. My Windows 7 system has 211 locales installed (listed below), so you wouldn't likely write any custom code or translation specific to this many locales.

The most important thing for various versions of English is in formatting numbers and dates. Other differences are significant to the extent that you want and able to cater to specific variations.

JUnit 4 does not have any out-of-the-box mechanism for a test case to get it’s own name (including during setup and teardown).

For the record, none of the aforementioned Git Python libraries seem to contain a "git status" equivalent, which is really the only thing I would want since dealing with the rest of the git commands via subprocess is so easy.

1. There's no need to call equals if hashCode differs.
2. There's no need to call hashCode if (obj1 == obj2).
3. There's no need for hashCode and/or equals just to iterate - you're not comparing objects
4. When needed to distinguish in between objects.

If you are doing this for virtualenv, the kernels in inactive environments might not be shown with jupyter kernelspec list, as suggested above. You can delete it from directory:

[Update Sep 2016]: This answer was intended for docker compose file v1 (as shown by the sample compose file below). For v2, see the other answer by @Windsooon.

[Original answer]:

It is pretty clear in the documentation. depends_on decides the dependency and the order of container creation and links not only does these, but also

Containers for the linked service will be reachable at a hostname identical to the alias, or the service name if no alias was specified.

For example, assuming the following docker-compose.yml file:

web:
  image: example/my_web_app:latest
  links:
    - db
    - cache

db:
  image: postgres:latest

cache:
  image: redis:latest

With links, code inside web will be able to access the database using db:5432, assuming port 5432 is exposed in the db image. If depends_on were used, this wouldn't be possible, but the startup order of the containers would be correct.

For people who want to use another diff tool not listed in git, say with nvim. here is what I ended up using:

git config --global alias.d difftool -x <tool name>

In my case, I set <tool name> to nvim -d and invoke the diff command with

git d <file>

I had similar problem, then I tried writing this from JavaScript and it works! : referenceToYourInputFile.value = "" ;

• Click on on distribute the app
• Click the distribution method
• Choose the export in the next screen (The screen shown only if the archive is validated)

On Unix systems that supports it (not macOS it seems):

if getent passwd "$username" >/dev/null; then
    printf 'User %s exists\n' "$username"
else
    printf 'User %s does not exist\n' "$username"
fi 

This has the advantage that it will query any directory service that may be in use (YP/NIS or LDAP etc.) and the local password database file.

The issue with grep -q "$username" /etc/passwd is that it will give a false positive when there is no such user, but something else matches the pattern. This could happen if there is a partial or exact match somewhere else in the file.

For example, in my passwd file, there is a line saying

build:*:21:21:base and xenocara build:/var/empty:/bin/ksh

This would provoke a valid match on things like cara and enoc etc., even though there are no such users on my system.

For a grep solution to be correct, you will need to properly parse the /etc/passwd file:

if cut -d ':' -f 1 /etc/passwd | grep -qxF "$username"; then
    # found
else
    # not found
fi

... or any other similar test against the first of the :-delimited fields.

There is nothing special about <input type="hidden">:

$('input[type="hidden"]').val()

There's a set of useful extensions to IDLE called IDLEX that works with MacOS and Windows http://idlex.sourceforge.net/

It includes line numbering and I find it quite handy & free.

Otherwise there are a bunch of other IDEs some of which are free: https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

When you use addEventListener, this will be bound automatically. So if you want a reference to the element on which the event handler is installed, just use this from within your function:

productLineSelect.addEventListener('change',getSelection,false);

function getSelection(){
    var value = sel.options[this.selectedIndex].value;
    alert(value);
}

If you want to pass in some other argument from the context where you call addEventListener, you can use a closure, like this:

productLineSelect.addEventListener('change', function(){ 
    // pass in `this` (the element), and someOtherVar
    getSelection(this, someOtherVar); 
},false);

function getSelection(sel, someOtherVar){
    var value = sel.options[sel.selectedIndex].value;
    alert(value);
    alert(someOtherVar);
}

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view
        private TextView footerTextView;

        public ViewHolder(final View itemView) {
            super(itemView);

            // Get the view of the elements of first list
            mTextDescription1 = (TextView) itemView.findViewById(R.id.description1);
            mListItemTitle1 = (TextView) itemView.findViewById(R.id.title1);

            // Get the view of the elements of second list
            mTextDescription2 = (TextView) itemView.findViewById(R.id.description2);
            mListItemTitle2 = (TextView) itemView.findViewById(R.id.title2);

            // Get the view of the footer elements
            footerTextView = (TextView) itemView.findViewById(R.id.footer);
        }

                else pos = pos - firstList.size() - 2;
            }

            final String description = secondList.get(pos).getDescription();
            final String title = secondList.get(pos).getTitle();

            mTextDescription2.setText(description);
            mListItemTitle2.setText(title);
        }

        public void bindViewFirstList(int pos) {

            // Decrease pos by 1 as there is a header view now.
            pos = pos - 1;

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

You can open up to 3 files in the same view by pressing [CTRL] + [^]

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

Yes, let's use Select as an example

sample code: Columns("A").select

How to loop through Columns:

Method 1: (You can use index to replace the Excel Address)

For i = 1 to 100
    Columns(i).Select
next i

Method 2: (Using the address)

For i = 1 To 100
 Columns(Columns(i).Address).Select
Next i

EDIT: Strip the Column for OP

columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")

e.g. you want to get the 27th Column --> AA, you can get it this way

All of the other answers here are correct but do not explain why what you were trying was wrong. When you do myList[i[0]] you are telling Python that i is a tuple and you want the value or the first element of tuple i as the index for myList.

In the majority of programming languages when you need to access a nested data type (such as arrays, lists, or tuples), you append the brackets to get to the innermost item. The first bracket gives you the location of the tuple in your list. The second bracket gives you the location of the item in the tuple.

This is a quick rudimentary example that I came up with:

info = [ ( 1, 2), (3, 4), (5, 6) ]

info[0][0] == 1
info[0][1] == 2
info[1][0] == 3
info[1][1] == 4
info[2][0] == 5
info[2][1] == 6

If you are seeing an error something like

error on line -1 c:apacheconfopenssl.cnf

try changing from back slash to front slash in the -config.

You can try FileUtils from org.apache.commons.io.FileUtils, try downloading jar from here

and you can use the following method: FileUtils.readFileToString("yourFileName");

Hope it helps you..

So if you actually want to find executable file types (e.g. scripts, ELF binaries etc.. etc..) not merely files with execution permission then you probably want to do something more like this (where the current directory . can be replaced with whatever directory you want):

 gfind . -type f -exec bash -c '[[ $(file -b "'{}'") == *" executable "* ]] ' \; -print

Or for those of you who aren't using macports (linux users) or otherwise have gnu find installed as find you want:

 find . -type f -exec bash -c '[[ $(file -b "'{}'") == *" executable "* ]] ' \; -print

Though if you are on OS X it comes with a little utility hidden somewhere called is_exec that basically bundles up that little test for you so you can shorten the command line if you find it. But this way is more flexible as you can easily replace the == test with the =~ test and use it to check for more complex properties like executable plain text files or whatever other info your file command returns.

The exact rules for quotation here are pretty opaque so I just end up working it out by trial and error but I'd love to hear the right explanation.

How about

with open(csv_input_path + file, 'r') as ft:
    header = ft.readline() # read only first line; returns string
    header_list = header.split(',') # returns list

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.

Try this:

var alphaExp = /^[a-zA-Z]+$/;
            if(document.myForm.name.match(alphaExp))
            {
                //Your logice will be here.
            }
            else{
                alert("Please enter only alphabets");
            }

Thanks.

You can use something like this:

for i in `cat foo.txt`
do
    sudo $i
done

Though if the commands have arguments (i.e. there is whitespace in the lines) you may have to monkey around with that a bit to protect the whitepace so that the whole string is seen by sudo as a command. But it gives you an idea on how to start.

Make a class that will fit table cell width to content

.table td.fit, 
.table th.fit {
    white-space: nowrap;
    width: 1%;
}

This gives you:

• The FK itself itself
• Schema that the FK belongs to
• The "referencing table" or the table that has the FK
• The "referencing column" or the column inside referencing table that points to the FK
• The "referenced table" or the table that has the key column that your FK is pointing to
• The "referenced column" or the column that is the key that your FK is pointing to

Code below:

SELECT  obj.name AS FK_NAME,
    sch.name AS [schema_name],
    tab1.name AS [table],
    col1.name AS [column],
    tab2.name AS [referenced_table],
    col2.name AS [referenced_column]
FROM sys.foreign_key_columns fkc
INNER JOIN sys.objects obj
    ON obj.object_id = fkc.constraint_object_id
INNER JOIN sys.tables tab1
    ON tab1.object_id = fkc.parent_object_id
INNER JOIN sys.schemas sch
    ON tab1.schema_id = sch.schema_id
INNER JOIN sys.columns col1
    ON col1.column_id = parent_column_id AND col1.object_id = tab1.object_id
INNER JOIN sys.tables tab2
    ON tab2.object_id = fkc.referenced_object_id
INNER JOIN sys.columns col2
    ON col2.column_id = referenced_column_id AND col2.object_id = tab2.object_id

Recent versions of JavaScript will read an ISO8601 formatted date, so all you have to do is change the space to a 'T', doing something like one of the following:

#MySQL
select date_format(my_date_column,'%Y-%m-%dT%T') from my_table;

#PHP
$php_date_str = substr($mysql_date_str,0,10).'T'.substr($mysql_date_str,11,8);

//JavaScript
js_date_str = mysql_date_str.substr(0,10)+'T'+mysql_date_str.substr(11,8);

If you only want to have glyphicons icons without any additional css you can create a css file and put the code below and include it into main css file.

I have to create this extra file as link below was messing with my site styles too.

Instead to using it directly I created a css file bootstrap-glyphicons.css

This confusion is because URLs are still 'broken' to this day.

Take "http://www.google.com" for instance. This is a URL. A URL is a Uniform Resource Locator and is really a pointer to a web page (in most cases). URLs actually have a very well-defined structure since the first specification in 1994.

We can extract detailed information about the "http://www.google.com" URL:

+---------------+-------------------+
|      Part     |      Data         |
+---------------+-------------------+
|  Scheme       | http              |
|  Host         | www.google.com    |
+---------------+-------------------+

If we look at a more complex URL such as:

"https://bob:[email protected]:8080/file;p=1?q=2#third"

we can extract the following information:

+-------------------+---------------------+
|        Part       |       Data          |
+-------------------+---------------------+
|  Scheme           | https               |
|  User             | bob                 |
|  Password         | bobby               |
|  Host             | www.lunatech.com    |
|  Port             | 8080                |
|  Path             | /file;p=1           |
|  Path parameter   | p=1                 |
|  Query            | q=2                 |
|  Fragment         | third               |
+-------------------+---------------------+

https://bob:[email protected]:8080/file;p=1?q=2#third
\___/   \_/ \___/ \______________/ \__/\_______/ \_/ \___/
  |      |    |          |          |      | \_/  |    |
Scheme User Password    Host       Port  Path |   | Fragment
        \_____________________________/       | Query
                       |               Path parameter
                   Authority

The reserved characters are different for each part.

For HTTP URLs, a space in a path fragment part has to be encoded to "%20" (not, absolutely not "+"), while the "+" character in the path fragment part can be left unencoded.

Now in the query part, spaces may be encoded to either "+" (for backwards compatibility: do not try to search for it in the URI standard) or "%20" while the "+" character (as a result of this ambiguity) has to be escaped to "%2B".

This means that the "blue+light blue" string has to be encoded differently in the path and query parts:

"http://example.com/blue+light%20blue?blue%2Blight+blue".

From there you can deduce that encoding a fully constructed URL is impossible without a syntactical awareness of the URL structure.

This boils down to:

You should have %20 before the ? and + after.

This has nothing to do with using PDO, it's just that you are confusing INSERT and UPDATE.

Here's the difference:

• INSERT creates a new row. I'm guessing that you really want to create a new row.
• UPDATE changes the values in an existing row, but if this is what you're doing you probably should use a WHERE clause to restrict the change to a specific row, because the default is that it applies to every row.

So this will probably do what you want:

$sql = "INSERT INTO `access_users`   
  (`contact_first_name`,`contact_surname`,`contact_email`,`telephone`) 
  VALUES (:firstname, :surname, :email, :telephone);
  ";

Note that I've also changed the order of columns; the order of your columns must match the order of values in your VALUES clause.

MySQL also supports an alternative syntax for INSERT:

$sql = "INSERT INTO `access_users`   
  SET `contact_first_name` = :firstname,
    `contact_surname` = :surname,
    `contact_email` = :email,
    `telephone` = :telephone
  ";

This alternative syntax looks a bit more like an UPDATE statement, but it creates a new row like INSERT. The advantage is that it's easier to match up the columns to the correct parameters.

An excerpt from an apple technical note (Thanks to matthias-bauch)

Xcode includes all your command-line tools. If it is installed on your system, remove it to uninstall your tools.

If your tools were downloaded separately from Xcode, then they are located at /Library/Developer/CommandLineTools on your system. Delete the CommandLineTools folder to uninstall them.

you could easily delete using terminal:

Here is an article that explains how to remove the command line tools but do it at your own risk.Try this only if any of the above doesn't work.

I think you can right click to your solution/project and click "Clean" button.

As far as I remember it was working like that. I don't have my VS.NET with me now so can't test it.

If you want two objects with the same elements but in a different order to compare equal, then the obvious thing to do is compare sorted copies of them - for instance, for the dictionaries represented by your JSON strings a and b:

import json

a = json.loads("""
{
    "errors": [
        {"error": "invalid", "field": "email"},
        {"error": "required", "field": "name"}
    ],
    "success": false
}
""")

b = json.loads("""
{
    "success": false,
    "errors": [
        {"error": "required", "field": "name"},
        {"error": "invalid", "field": "email"}
    ]
}
""")

>>> sorted(a.items()) == sorted(b.items())
False

... but that doesn't work, because in each case, the "errors" item of the top-level dict is a list with the same elements in a different order, and sorted() doesn't try to sort anything except the "top" level of an iterable.

To fix that, we can define an ordered function which will recursively sort any lists it finds (and convert dictionaries to lists of (key, value) pairs so that they're orderable):

def ordered(obj):
    if isinstance(obj, dict):
        return sorted((k, ordered(v)) for k, v in obj.items())
    if isinstance(obj, list):
        return sorted(ordered(x) for x in obj)
    else:
        return obj

If we apply this function to a and b, the results compare equal:

>>> ordered(a) == ordered(b)
True

Use x11docker by mviereck:

https://github.com/mviereck/x11docker#hardware-acceleration says

Hardware acceleration

Hardware acceleration for OpenGL is possible with option -g, --gpu.

This will work out of the box in most cases with open source drivers on host. Otherwise have a look at wiki: feature dependencies. Closed source NVIDIA drivers need some setup and support less x11docker X server options.

This script is really convenient as it handles all the configuration and setup. Running a docker image on X with gpu is as simple as

x11docker --gpu imagename

>>> def dict2obj(d):
        if isinstance(d, list):
            d = [dict2obj(x) for x in d]
        if not isinstance(d, dict):
            return d
        class C(object):
            pass
        o = C()
        for k in d:
            o.__dict__[k] = dict2obj(d[k])
        return o


>>> d = {'a': 1, 'b': {'c': 2}, 'd': ["hi", {'foo': "bar"}]}
>>> x = dict2obj(d)
>>> x.a
1
>>> x.b.c
2
>>> x.d[1].foo
'bar'

If you git stash pop (with no conflicts) it will remove the stash after it is applied. But if you git stash apply it will apply the patch without removing it from the stash list. Then you can revert the unwanted changes with git checkout -- files...

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

save as png solved the problem for me.

Make sure you have settings.xml. I had the same problem when I've deleted it by mistake.

To simplify the answare let's look on the following code:

#include "stdafx.h"
#include <iostream>
using namespace std;

class A
{
private:
    int m_id;
    static int count;
public:
    A() {count++; m_id = count;}
    A(int id) { m_id = id; }
    ~A() {cout<< "Destructor A "   <<m_id<<endl; }
};

int A::count = 0;

void f1()
{   
    A* arr = new A[10];
    //delete operate only one constructor, and crash!
    delete arr;
    //delete[] arr;
}

int main()
{
    f1();
    system("PAUSE");
    return 0;
}

The output is: Destructor A 1 and then it's crashing (Expression: _BLOCK_TYPE_IS_VALID(phead- nBlockUse)).

We need to use: delete[] arr; becuse it's delete the whole array and not just one cell!

try to use delete[] arr; the output is: Destructor A 10 Destructor A 9 Destructor A 8 Destructor A 7 Destructor A 6 Destructor A 5 Destructor A 4 Destructor A 3 Destructor A 2 Destructor A 1

The same principle is for an array of pointers:

void f2()
{
    A** arr = new A*[10];
    for(int i = 0; i < 10; i++)
    {
        arr[i] = new A(i);
    }
    for(int i = 0; i < 10; i++)
    {
        delete arr[i];//delete the A object allocations.
    }

    delete[] arr;//delete the array of pointers
}

if we'll use delete arr instead of delete[] arr. it will not delete the whole pointers in the array => memory leak of pointer objects!

these will help you...

There are two main differences.

Accessing the association sides

The first one is related to how you will access the relationship. For a unidirectional association, you can navigate the association from one end only.

So, for a unidirectional @ManyToOne association, it means you can only access the relationship from the child side where the foreign key resides.

If you have a unidirectional @OneToMany association, it means you can only access the relationship from the parent side which manages the foreign key.

For the bidirectional @OneToMany association, you can navigate the association in both ways, either from the parent or from the child side.

You also need to use add/remove utility methods for bidirectional associations to make sure that both sides are properly synchronized.

Performance

The second aspect is related to performance.

1. For @OneToMany, unidirectional associations don't perform as well as bidirectional ones.
2. For @OneToOne, a bidirectional association will cause the parent to be fetched eagerly if Hibernate cannot tell whether the Proxy should be assigned or a null value.
3. For @ManyToMany, the collection type makes quite a difference as Sets perform better than Lists.

You need to build a custom class-loader to do this or a third-party library that supports this. Your best bet is to extract the jar from the runtime and add them to the classpath (or have them already added to the classpath).

you can use below code to check for brokers available if server is running.

import org.I0Itec.zkclient.ZkClient;
     public static boolean isBrokerRunning(){
        boolean flag = false;
        ZkClient zkClient = new ZkClient(endpoint.getZookeeperConnect(), 10000);//, kafka.utils.ZKStringSerializer$.MODULE$);
        if(zkClient!=null){
            int brokersCount = zkClient.countChildren(ZkUtils.BrokerIdsPath());
            if(brokersCount > 0){
                logger.info("Following Broker(s) {} is/are available on Zookeeper.",zkClient.getChildren(ZkUtils.BrokerIdsPath()));
                flag = true;    
            }
            else{
                logger.error("ERROR:No Broker is available on Zookeeper.");
            }
            zkClient.close();

        }
        return flag;
    }

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

MotionEvent is generated only by touching the screen.

I found that "@RequestMapping produces=" and other configuration changes didn't help me. By the time you do resp.getWriter(), it is also too late to set the encoding on the writer.

Adding a header to the HttpServletResponse works.

@RequestMapping(value="/test", method=RequestMethod.POST)
public void test(HttpServletResponse resp) {
    try {
        resp.addHeader("content-type", "application/json; charset=utf-8");
        PrintWriter w = resp.getWriter();
        w.write("{\"name\" : \"µr µicron\"}");
        w.flush();
        w.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

The encrypted string had two special characters, + and =.

'+' sign was giving the error, so below solution worked well:

//replace + sign

encryted_string = encryted_string.Replace("+", "%2b");

//`%2b` is HTTP encoded string for **+** sign

OR

//encode special charactes 

encryted_string = HttpUtility.UrlEncode(encryted_string);

//then pass it to the decryption process
...

I answered something like this in another question already, but will change it just a little for this one.

Unfortunately, there is no getImageResource() or getDrawableId(). But, I created a simple workaround by using the ImageView tags.

In onCreate():

imageView0 = (ImageView) findViewById(R.id.imageView0);
imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView2 = (ImageView) findViewById(R.id.imageView2);

imageView0.setTag(R.drawable.apple);
imageView1.setTag(R.drawable.banana);
imageView2.setTag(R.drawable.cereal);

Then, if you like, you can create a simple function to get the drawable id:

private int getDrawableId(ImageView iv) {
    return (Integer) iv.getTag();
}

Too easy.

Actually every object in javascript resolves to true if it has "a real value" as W3Cschools puts it. That means everything except "", NaN, undefined, null or 0.

Testing a number against a boolean with the == operator indeed is a tad weird, since the boolean gets converted into numerical 1 before comparing, which defies a little bit the logic behind the definition. This gets even more confusing when you do something like this:

    var fred = !!3; // will set fred to true _x000D_
    var joe = !!0; // will set joe to false_x000D_
    alert("fred = "+ fred + ", joe = "+ joe);

not everything in javascript makes a lot of sense ;)
