All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

I had this issue with a solution containing multiple projects.

It came from duplicating a .csproj and adding the copy to the solution. A .csproj file contains a <ProjectGuid> element. I set the GUID of the copied project to a new one.

Update: Which GUID you use doesn't matter, it just needs to be different from the other project's GUID. You can create a new GUID from within Visual Studio: Tools -> Create GUID and copy the part between the curly brackets, i.e. {...}. Use that as the new value for the <ProjectGuid> element.

I also performed the following steps (not neccessarily neccessary, but they don't hurt):

1. Close the solution
2. Delete bin folder
3. Delete all obj folders
4. Open solution and build

For more performance: A simple change is observing that after n = 3n+1, n will be even, so you can divide by 2 immediately. And n won't be 1, so you don't need to test for it. So you could save a few if statements and write:

while (n % 2 == 0) n /= 2;
if (n > 1) for (;;) {
    n = (3*n + 1) / 2;
    if (n % 2 == 0) {
        do n /= 2; while (n % 2 == 0);
        if (n == 1) break;
    }
}

Here's a big win: If you look at the lowest 8 bits of n, all the steps until you divided by 2 eight times are completely determined by those eight bits. For example, if the last eight bits are 0x01, that is in binary your number is ???? 0000 0001 then the next steps are:

3n+1 -> ???? 0000 0100
/ 2  -> ???? ?000 0010
/ 2  -> ???? ??00 0001
3n+1 -> ???? ??00 0100
/ 2  -> ???? ???0 0010
/ 2  -> ???? ???? 0001
3n+1 -> ???? ???? 0100
/ 2  -> ???? ???? ?010
/ 2  -> ???? ???? ??01
3n+1 -> ???? ???? ??00
/ 2  -> ???? ???? ???0
/ 2  -> ???? ???? ????

So all these steps can be predicted, and 256k + 1 is replaced with 81k + 1. Something similar will happen for all combinations. So you can make a loop with a big switch statement:

k = n / 256;
m = n % 256;

switch (m) {
    case 0: n = 1 * k + 0; break;
    case 1: n = 81 * k + 1; break; 
    case 2: n = 81 * k + 1; break; 
    ...
    case 155: n = 729 * k + 425; break;
    ...
}

Run the loop until n = 128, because at that point n could become 1 with fewer than eight divisions by 2, and doing eight or more steps at a time would make you miss the point where you reach 1 for the first time. Then continue the "normal" loop - or have a table prepared that tells you how many more steps are need to reach 1.

PS. I strongly suspect Peter Cordes' suggestion would make it even faster. There will be no conditional branches at all except one, and that one will be predicted correctly except when the loop actually ends. So the code would be something like

static const unsigned int multipliers [256] = { ... }
static const unsigned int adders [256] = { ... }

while (n > 128) {
    size_t lastBits = n % 256;
    n = (n >> 8) * multipliers [lastBits] + adders [lastBits];
}

In practice, you would measure whether processing the last 9, 10, 11, 12 bits of n at a time would be faster. For each bit, the number of entries in the table would double, and I excect a slowdown when the tables don't fit into L1 cache anymore.

PPS. If you need the number of operations: In each iteration we do exactly eight divisions by two, and a variable number of (3n + 1) operations, so an obvious method to count the operations would be another array. But we can actually calculate the number of steps (based on number of iterations of the loop).

We could redefine the problem slightly: Replace n with (3n + 1) / 2 if odd, and replace n with n / 2 if even. Then every iteration will do exactly 8 steps, but you could consider that cheating :-) So assume there were r operations n <- 3n+1 and s operations n <- n/2. The result will be quite exactly n' = n * 3^r / 2^s, because n <- 3n+1 means n <- 3n * (1 + 1/3n). Taking the logarithm we find r = (s + log2 (n' / n)) / log2 (3).

If we do the loop until n = 1,000,000 and have a precomputed table how many iterations are needed from any start point n = 1,000,000 then calculating r as above, rounded to the nearest integer, will give the right result unless s is truly large.

I think you can find it usefull

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-two-datasources

It shows how to define multiple datasources & assign one of them as primary.

Here is a rather full example, also contains distributes transactions - if you need it.

http://fabiomaffioletti.me/blog/2014/04/15/distributed-transactions-multiple-databases-spring-boot-spring-data-jpa-atomikos/

What you need is to create 2 configuration classes, separate the model/repository packages etc to make the config easy.

Also, in above example, it creates the data sources manually. You can avoid this using the method on spring doc, with @ConfigurationProperties annotation. Here is an example of this:

http://xantorohara.blogspot.com.tr/2013/11/spring-boot-jdbc-with-multiple.html

Hope these helps.

I think you can use substring method to get name of the file from the path string.

String path=":/storage/sdcard0/DCIM/Camera/1414240995236.jpg"; 
// it contains your image path...I'm using a temp string...
String filename=path.substring(path.lastIndexOf("/")+1);

Here's an example in C# (cause that's what I was searching for). I needed to split a 23 GB csv-file with around 175 million lines to be able to look at the files. I split it into files of one million rows each. This code did it in about 5 minutes on my machine:

var list = new List<string>();
var fileSuffix = 0;

using (var file = File.OpenRead(@"D:\Temp\file.csv"))
using (var reader = new StreamReader(file))
{
    while (!reader.EndOfStream)
    {
        list.Add(reader.ReadLine());

        if (list.Count >= 1000000)
        {
            File.WriteAllLines(@"D:\Temp\split" + (++fileSuffix) + ".csv", list);
            list = new List<string>();
        }
    }
}

File.WriteAllLines(@"D:\Temp\split" + (++fileSuffix) + ".csv", list);

Why don't you use spring's TransactionTemplate to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional method, but given that it's a test I would opt for programmatic control of your transactions.

Also note that the @Transactional annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!

@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {

@Autowired
PlatformTransactionManager platformTransactionManager;

TransactionTemplate transactionTemplate;

@Before
public void setUp() throws Exception {
    transactionTemplate = new TransactionTemplate(platformTransactionManager);
}

@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {

    final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
        @Override
        public Contract doInTransaction(TransactionStatus status) {
            Contract c = contractDOD.getNewTransientContract(15);
            contractRepository.save(c);
            return c;
        }
    });

    ExecutorService executorService = Executors.newFixedThreadPool(5);

    for (int i = 0; i < 5; ++i) {
        executorService.execute(new Runnable() {
            @Override  //note that there is no @Transactional configured for the method
            public void run() {
                transactionTemplate.execute(new TransactionCallback<Object>() {
                    @Override
                    public Object doInTransaction(TransactionStatus status) {
                        // do whatever you want to do with c1
                        return null;
                    }
                });
            }
        });
    }

    executorService.shutdown();
    executorService.awaitTermination(10, TimeUnit.SECONDS);

    transactionTemplate.execute(new TransactionCallback<Object>() {
        @Override
        public Object doInTransaction(TransactionStatus status) {
            // validate test results in transaction
            return null;
        }
    });
}

}

If have development pod Delete your app from simulator install from pod -> clean - > run again...

Well, your script throws an error and you just need to catch it (and/or prevent it from happening). I had the same error, for me it was an already used port (EADDRINUSE).

You can bypass https using below commands:

npm config set strict-ssl false

or set the registry URL from https or http like below:

npm config set registry="http://registry.npmjs.org/"

However, Personally I believe bypassing https is not the real solution, but we can use it as a workaround.

Try to set up the correct target in Podfile and then run pod update or pod install

<html>
<body>
    <video width="600" height="400" controls>
        <source src="index.m3u8" type="application/x-mpegURL">
    </video>
</body> 

Stream HLS or m3u8 files using above code. it works for desktop: ms edge browser (not working with desktop chrome) and mobile: chrome,opera mini browser.

To play on all browser use flash based media player. media player to support all browser

Also you can download and execute the install.bat file in 'ODAC112030Xcopy.zip' from 64-bit Oracle Data Access Components (ODAC) Downloads. This resolved my problem.

This works fine for me.

f = open(file_path, 'r+', encoding="utf-8")

You can add a third parameter encoding to ensure the encoding type is 'utf-8'

Note: this method works fine in Python3, I did not try it in Python2.7.

You can just as easily access each element in the list using e.g. path[[1]]. You can't put a set of matrices into an atomic vector and access each element. A matrix is an atomic vector with dimension attributes. I would use the list structure returned by split, it's what it was designed for. Each list element can hold data of different types and sizes so it's very versatile and you can use *apply functions to further operate on each element in the list. Example below.

#  For reproducibile data
set.seed(1)

#  Make some data
userid <- rep(1:2,times=4)
data1 <- replicate(8 , paste( sample(letters , 3 ) , collapse = "" ) )
data2 <- sample(10,8)
df <- data.frame( userid , data1 , data2 )

#  Split on userid
out <- split( df , f = df$userid )
#$`1`
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

#$`2`
#  userid data1 data2
#2      2   xfv     4
#4      2   bfe    10
#6      2   mrx     2
#8      2   fqd     9

Access each element using the [[ operator like this:

out[[1]]
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

Or use an *apply function to do further operations on each list element. For instance, to take the mean of the data2 column you could use sapply like this:

sapply( out , function(x) mean( x$data2 ) )
#   1    2 
#3.75 6.25 

I solved this by deleting d:\test\mongodb\data\mongod.lock file. When you will reconnect mongo db than this file will auto generate in same folder. it works for me.

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

new answer (fast)

You can make bash do the math for you, and it works with milliseconds.

toSeconds() {
    awk -F: 'NF==3 { print ($1 * 3600) + ($2 * 60) + $3 } NF==2 { print ($1 * 60) + $2 } NF==1 { print 0 + $1 }' <<< $1
}

StartSeconds=$(toSeconds "45.5")
EndSeconds=$(toSeconds "1:00.5")
Duration=$(bc <<< "(${EndSeconds} + 0.01) - ${StartSeconds}" | awk '{ printf "%.4f", $0 }')
ffmpeg -ss $StartSeconds -i input.mpg -t $Duration output.mpg

This, like the old answer, will produce a 15 second clip. This method is ideal even when clipping from deep within a large file because seeking isn't disabled, unlike the old answer. And yes, I've verified it's frame perfect.

NOTE: The start-time is INCLUSIVE and the end-time is normally EXCLUSIVE, hence the +0.01, to make it inclusive.

If you use mpv you can enable millisecond timecodes in the OSD with --osd-fractions

old answer with explanation (slow)

To cut based on start and end time from the source video and avoid having to do math, specify the end time as the input option and the start time as the output option.

ffmpeg -t 1:00 -i input.mpg -ss 45 output.mpg

This will produce a 15 second cut from 0:45 to 1:00.

This is because when -ss is given as an output option, the discarded time is still included in the total time read from the input, which -t uses to know when to stop. Whereas if -ss is given as an input option, the start time is seeked and not counted, which is where the confusion comes from.

It's slower than seeking since the omitted segment is still processed before being discarded, but this is the only way to do it as far as I know. If you're clipping from deep within a large file, it's more prudent to just do the math and use -ss for the input.

Go to gradle.properties file (project root directory) and add these options.

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=localhost

Setting CommandTimeout to 120 is not recommended. Try using pagination as mentioned above. Setting CommandTimeout to 30 is considered as normal. Anything more than that is consider bad approach and that usually concludes something wrong with the Implementation. Now the world is running on MiliSeconds Approach.

I resolved that problem just moving my project from E: to C:. I think it happened becouse nodejs and npm was installed in my C: and the project was in my E:

An svg dynamic solution for any screen is the following:

<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" stroke-width="1" stroke="#000">
  <line x1="0" y1="0" x2="100%" y2="100%"/>
  <line x1="100%" y1="0" x2="0" y2="100%"/>
</svg>

And if you want to keep it in background use the position: absolute with top and left 0.

I tried all the stuff I found on the net (npm cache clear and rm -rf ~/.npm), but nothing seems to work. What solved the issue was updating node (and npm) to the latest version. Try that.

In my case, I had to uninstall pip and reinstall it. So I could install my specific version.

sudo apt-get purge --auto-remove python-pip
sudo easy_install pip 

You can directly install an github repo by npm install command, like this: npm install https://github.com/futurechallenger/npm_git_install.git --save

NOTE: In the repo which will be installed by npm command:

1. maybe you have to have a dist folder in you repo, according to @Dan Dascalescu's comment.
2. You definitely have to have a package.json in you repo! which I forget add.

To avoid all the Oracle mess of not knowing where it is looking for the TNSNAMES.ORA (I have the added confusion of multiple Oracle versions and 32/64 bit), you can copy the setting from your existing TNSNAMES.ORA to your own config file and use that for your connection.
Say you're happy with the 'DSDSDS' reference in TNSNAMES.ORA which maps to something like:

DSDSDS=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=DSDSDSHost)(Port=4521)))(CONNECT_DATA=(SERVICE_NAME=DSDSDSService)))

The reason you don't have permissions to open file is because you didn't grant other apps to open or view the file on your intent. To grant other apps to open the downloaded file, include the flag(as shown below): FLAG_GRANT_READ_URI_PERMISSION

Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.setDataAndType(getUriFromFile(localFile), "application/pdf");
browserIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION|
Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(browserIntent);

And for function:

getUriFromFile(localFile)

private Uri getUriFromFile(File file){
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
        return Uri.fromFile(file);
    }else {
        return FileProvider.getUriForFile(itemView.getContext(), itemView.getContext().getApplicationContext().getPackageName() + ".provider", file);
    }
}

I had to do a combination of two of the above comments.

Both Setting the Default Project within the Package Manager Console, and also Abhinandan comments of adding the -ContextTypeName variable to my full command. So my command was as follows..

Enable-Migrations -StartUpProjectName RapidDeploy -ContextTypeName RapidDeploy.Models.BloggingContext -Verbose

My Settings::

• ProjectName - RapidDeploy
• BloggingContext (Class Containing DbContext, file is within Models folder of Main Project)

In case you prefer to use jQuery to set the image from Base64:

$("#img").attr('src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==');

If you're unlucky enough to be switching back and forth from a network behind a proxy and a network NOT behind a proxy, you may have forgotten that your NPM config is set to expect a proxy.

For me, I had to open up ~/.npmrc and comment out my proxy settings (while at home) and vice versa while at work (behind the proxy).

This is all that you had to do man, change his MyViewModel model to IList.

One and/or multiple of those should help:

1. Add C:\Python27\ to your PATH variable (considering you have Python installed in this directory)
   How to set PATH env variable: http://www.computerhope.com/issues/ch000549.htm
   Restart your console and/or Windows after setting variable.

2. In the same section as above ("Environment Variables"), add new variable with name PYTHON and value C:\Python27\python.exe
   Restart your console and/or Windows after setting variable.

3. Open Windows command line (cmd) in Admin mode.
   Change directory to your Python installation path: cd C:\Python27
   Make symlink needed for some installations: mklink python2.7.exe python.exe

Please note that you should have Python 2.x, NOT 3.x, to run node-gyp based installations!

The text below says about Unix, but Windows version also requires Python 2.x:

You can install with npm:

$ npm install -g node-gyp
You will also need to install:

On Unix:
python (v2.7 recommended, v3.x.x is not supported)
make
A proper C/C++ compiler toolchain, like GCC

I think there's a simpler solution: Just use the DialogInterface argument that is passed to the onClick method.

AlertDialog.Builder db = new AlertDialog.Builder(context);
        db.setNegativeButton("cancel", new DialogInterface.OnClickListener(){
            @Override
            public void onClick(DialogInterface d, int arg1) {
                db.cancel();
                //here db.cancel will dismiss the builder

            };  
        });

See, for example, http://www.mkyong.com/android/android-alert-dialog-example.

None of previous answers worked for me.

I noticed that my project was referencing another project using the System.Web.Mvc reference from the .NET Framework.

I just deleted that assembly and added the "Microsoft.AspNet.Mvc" NuGet package and that fixed my problem.

This answer comes late but summarizes the concept involved in the "table not mapped" exception(in order to help those who come across this problem since its very common for hibernate newbies). This error can appear due to many reasons but the target is to address the most common one that is faced by a number of novice hibernate developers to save them hours of research. I am using my own example for a simple demonstration below.

The exception:

org.hibernate.hql.internal.ast.QuerySyntaxException: subscriber is not mapped [ from subscriber]

In simple words, this very usual exception only tells that the query is wrong in the below code.

Session session = this.sessionFactory.getCurrentSession();
List<Subscriber> personsList = session.createQuery(" from subscriber").list();

This is how my POJO class is declared:

@Entity
@Table(name = "subscriber")
public class Subscriber

But the query syntax "from subscriber" is correct and the table subscriber exists. Which brings me to a key point:

• It is an HQL query not SQL.

and how its explained here

HQL works with persistent objects and their properties not with the database tables and columns.

Since the above query is an HQL one, the subscriber is supposed to be an entity name not a table name. Since I have my table subscriber mapped with the entity Subscriber. My problem solves if I change the code to this:

Session session = this.sessionFactory.getCurrentSession();
List<Subscriber> personsList = session.createQuery(" from Subscriber").list();

Just to keep you from getting confused. Please note that HQL is case sensitive in a number of cases. Otherwise it would have worked in my case.

Keywords like SELECT , FROM and WHERE etc. are not case sensitive but properties like table and column names are case sensitive in HQL.

https://www.tutorialspoint.com/hibernate/hibernate_query_language.htm

To further understand how hibernate mapping works, please read this

The reason you're getting the unhashable type: 'list' exception is because k = list[0:j] sets k to be a "slice" of the list, which is logically another, often shorter, list. What you need is to get just the first item in list, written like so k = list[0]. The same for v = list[j + 1:] which should just be v = list[2] for the third element of the list returned from the call to readline.split(" ").

I noticed several other likely problems with the code, of which I'll mention a few. A big one is you don't want to (re)initialize d with d = {} for each line read in the loop. Another is it's generally not a good idea to name variables the same as any of the built-ins types because it'll prevent you from being able to access one of them if you need it — and it's confusing to others who are used to the names designating one of these standard items. For that reason, you ought to rename your variable list variable something different to avoid issues like that.

Here's a working version of your with these changes in it, I also replaced the if statement expression you used to check to see if the key was already in the dictionary and now make use of a dictionary's setdefault() method to accomplish the same thing a little more succinctly.

d = {}
with open("nameerror.txt", "r") as file:
    line = file.readline().rstrip()
    while line:
        lst = line.split() # Split into sequence like ['AAA', 'x', '111'].
        k, _, v = lst[:3]  # Get first and third items.
        d.setdefault(k, []).append(v)
        line = file.readline().rstrip()

print('d: {}'.format(d))

Output:

d: {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}

I had this issue with npm v1.1.4 (and node v0.6.12), which are the Ubuntu 12.04 repository versions.

It looks like that version of npm isn't supported any more, updating node (and npm with it) resolved the issue.

First, uninstall the outdated version (optional, but I think this fixed an issue I was having with global modules not being pathed in).

sudo apt-get purge nodejs npm

Then enable nodesource's repo and install:

curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs

Note - the previous advice was to use Chris Lea's repo, he's now migrated that to nodesource, see:

• https://chrislea.com/2014/07/09/joining-forces-nodesource/
• https://nodesource.com/blog/chris-lea-joins-forces-with-nodesource

From: here

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

I found the there is a certificate expired issue with:

npm set registry https://registry.npmjs.org/

So I made it http, not https :-

npm set registry http://registry.npmjs.org/

And have no problems so far.

I've just done this for a project, and achieved it by using the h6 tag which I wasn't using for anything else:

in html code:

<h6><img alt="small drawing" src="../Images/image1.jpg" width="50%"/> <img alt="small drawing" src="../Images/image2.jpg" width="50%"/><br/>Optional caption text</h6>

The space between the image tags puts a vertical gap between the images. The width argument in each img tag is optional, but it neatly sizes the images to fill the width of the page. Notice that each image must be set to take up only 50% of the width. (Or 33% if you're using 3 images.) The width argument must come after the alt and src arguments or it won't work.

in css code:

/* h6: set presentation of images */
h6
  {
  font-family: "Franklin Gothic Demi", serif;
  font-size: 1.0em;
  font-weight: normal;
  line-height: 1.25em;
  text-align: center;
  }

The text items set the look of the caption text, and the text-align property centers both the images and the caption text.

Due to security violations, organizations may have their own repositories.

set your local repo as below.

npm config set registry https://yourorg-artifactory.com/

I hope this will solve the issue.

I had the same exception, caused when attempting to remove the kid from the person (Person - OneToMany - Kid). On Person side annotation:

@OneToMany(fetch = FetchType.EAGER, orphanRemoval = true, ... cascade    = CascadeType.ALL)
public Set<Kid> getKids() {    return kids; }

On Kid side annotation:

@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "person_id")
public Person getPerson() {        return person;    }

So solution was to remove cascade = CascadeType.ALL, just simple: @ManyToOne on the Kid class and it started to work as expected.

In my case I had a cherry pick that produce a number of Merge Conflicts, so I decide to not complete the cherry pick. I discarded all my changes. Doing so put me into a state where I received the following error:

You have not concluded your merge (MERGE_HEAD exists

To fix the issue I performed the following git command which fixed the problem.

git cherry-pick --abort

var canvasId = chart.id + '-canvas';
var canvasDownloadId = chart.id + '-download-canvas';
var canvasHtml = Ext.String.format('<canvas id="{0}" width="{1}" height="{2}"></canvas><a id="{3}"/>',
canvasId,
chart.getWidth(),
chart.getHeight(),
canvasDownloadId);
var canvasElement = reportBuilder.add({ html: canvasHtml });

var canvas = document.getElementById(canvasId);

var canvasDownload = document.getElementById(canvasDownloadId);
canvasDownload.href = chart.getImage().data;
canvasDownload.download = 'chart';

canvasDownload.click();

For Byron, you can try this..

public String test(){
                String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN 
                     where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
                List<String> li = jdbcTemplate.queryForList(sql,String.class);
                return li.get(0).toString();
        }

How to get Color from Hexadecimal color code using .NET?

This I think is what you are after, hope it answers your question.

To get your code to work use Convert.ToByte instead of Convert.ToInt...

string colour = "#ffaacc";

Color.FromRgb(
Convert.ToByte(colour.Substring(1,2),16),
Convert.ToByte(colour.Substring(3,2),16),
Convert.ToByte(colour.Substring(5,2),16));

You can do something like this.

 List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
    return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));

Output:

 {
  1: "abc",
  2: "def",
  3: "ghi"
}

The error SELF_SIGNED_CERT_IN_CHAIN means that you have self signed certificate in certificate chain which is basically not trusted by the system.

If that happens, basically something fishy is going on, therefore as people already commented, it is not recommended to just disable certificate checks, but better approach is to understand what is the problem and fix the cause of it.

This maybe related either to:

• custom repository address which doesn't have the right certificate,

• a corporate network with transparent proxy.

  If you're behind a corporate web proxy, you should set-up the proper HTTP_PROXY/HTTPS_PROXY environment variables or set them via npm:

    npm config set proxy http://proxy.company.com:8080
    npm config set https-proxy http://proxy.company.com:8080
  

  See: How to setup Node.js and Npm behind a corporate web proxy

If you trust the host, you can export the self-signed certificate from the chain and import them into system, so they're marked as trusted.

This can be achieved by checking the certificates by (change example.com into npm repo which is failing based on the npm-debug.log):

openssl s_client -showcerts -connect example.com:443 < /dev/null

then save the certificate content (between BEGIN and END) into .crt file in order to import it.

Linux

As per suggestion, you can add the below to the /etc/environment file (Node 7.4+) to export your CA chain, like:

NODE_EXTRA_CA_CERTS=/etc/pki/ca-trust/source/anchors/yourCer??ts.pem

CentOS

On CentOS 5 this can be appended into /etc/pki/tls/certs/ca-bundle.crt file, e.g.

ex +'g/BEGIN CERTIFICATE/,/END CERTIFICATE/p' <(echo | openssl s_client -showcerts -connect example.com:443) -scq | sudo tee -a /etc/pki/tls/certs/ca-bundle.crt
sudo update-ca-trust force-enable
sudo update-ca-trust extract
npm install

^{Note: To export only first certificate, remove g at the beginning.}

In CentOS 6, the certificate file can be copied to /etc/pki/ca-trust/source/anchors/.

Ubuntu/Debian

In Ubuntu/Debian, copy CRT file into /usr/local/share/ca-certificates/ then run:

sudo update-ca-certificates

macOS

In macOS you can run:

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/foo.crt

Windows

In Windows: certutil -addstore -f "ROOT" new-root-certificate.crt

See also: npm - Troubleshooting - SSL Error

Follwing the below steps you well get package.json file.

npm --version
npm install express
npm init -y

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Can also encode like below.... gathered from https://davidwalsh.name/domdocument-utf8-problem

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML(mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8'));
echo $dom->saveHTML();

In VS 2010 just right click on project or on reference and click add reference. On the popup window Select Assemblies - > Extensions -> System.Web.Helpers

This Works

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");
    document.body.appendChild(link);
    link.setAttribute("type", "hidden");
    link.href = "data:text/plain;base64," + base64;
    link.download = fileName;
    link.click();  
    document.body.removeChild(link);
}

Based on the answer above but with some changes

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

Here 2 pure bash solutions using only ffmpeg and not using

• an intermediary file
• perl, python nor javascript

One-liner solution using ls

ls video1.mp4 video2.mp4 | while read line; do echo file \'$line\'; done | ffmpeg -protocol_whitelist file,pipe -f concat -i - -c copy output.mp4

Function which takes 0 or 2+ arguments

#######################################
# Merge mp4 files into one output mp4 file
# usage:
#   mergemp4 #merges all mp4 in current directory
#   mergemp4 video1.mp4 video2.mp4
#   mergemp4 video1.mp4 video2.mp4 [ video3.mp4 ...] output.mp4 
#######################################
function mergemp4() {
  if [ $# = 1 ]; then return; fi

  outputfile="output.mp4"

  #if no arguments we take all mp4 in current directory as array
  if [ $# = 0 ]; then inputfiles=($(ls -1v *.mp4)); fi
  if [ $# = 2 ]; then inputfiles=($1 $2); fi  
  if [ $# -ge 3 ]; then
    outputfile=${@: -1} # Get the last argument
    inputfiles=(${@:1:$# - 1}) # Get all arguments besides last one as array
  fi
  
  # -y: automatically overwrite output file if exists
  # -loglevel quiet: disable ffmpeg logs
  ffmpeg -y \
  -loglevel quiet \
  -f concat \
  -safe 0 \
  -i <(for f in $inputfiles; do echo "file '$PWD/$f'"; done) \
  -c copy $outputfile

  if test -f "$outputfile"; then echo "$outputfile created"; fi
}

Note: had tried some solutions in this thread and none satisfied me

I was getting this when the app deployed. In my case, I chose "This is a full trust application" on the project security tab, and that fixed it.

You need to check for DBNull, not null. Additionally, two of your three ReplaceNull methods don't make sense. double and DateTime are non-nullable, so checking them for null will always be false...

Try this if you want to display the alert box to appear on the same page, without displaying on a blank page.

ScriptManager.RegisterStartupScript(this, GetType(), "showalert", "alert('Sorry there are no attachments');", true);

I believe you have libx264 installed and configured with ffmpeg to convert video to h264... Then you can try with -vcodec libx264... The -format option is for showing available formats, this is not a conversion option I think...

By the looks of it you need to actually pass drawImage an image object like so

var canvas = document.getElementById("c");_x000D_
var ctx = canvas.getContext("2d");_x000D_
_x000D_
var image = new Image();_x000D_
image.onload = function() {_x000D_
  ctx.drawImage(image, 0, 0);_x000D_
};_x000D_
image.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

<canvas id="c"></canvas>

I've tried it in chrome and it works fine.

I feel like an advanced necromancer here, but this is still an issue 4 years later in MVC5.

To handle ajax requests properly the anti-forgery token needs to be passed to the server on ajax calls. Integrating it into your post data and models is messy and unnecessary. Adding the token as a custom header is clean and reusable - and you can configure it so you don't have to remember to do it every time.

There is an exception - Unobtrusive ajax does not need special treatment for ajax calls. The token is passed as usual in the regular hidden input field. Exactly the same as a regular POST.

_Layout.cshtml

In _layout.cshtml I have this JavaScript block. It doesn't write the token into the DOM, rather it uses jQuery to extract it from the hidden input literal that the MVC Helper generates. The Magic string that is the header name is defined as a constant in the attribute class.

<script type="text/javascript">
    $(document).ready(function () {
        var isAbsoluteURI = new RegExp('^(?:[a-z]+:)?//', 'i');
        //http://stackoverflow.com/questions/10687099/how-to-test-if-a-url-string-is-absolute-or-relative

        $.ajaxSetup({
            beforeSend: function (xhr) {
                if (!isAbsoluteURI.test(this.url)) {
                    //only add header to relative URLs
                    xhr.setRequestHeader(
                       '@.ValidateAntiForgeryTokenOnAllPosts.HTTP_HEADER_NAME', 
                       $('@Html.AntiForgeryToken()').val()
                    );
                }
            }
        });
    });
</script>

Note the use of single quotes in the beforeSend function - the input element that is rendered uses double quotes that would break the JavaScript literal.

Client JavaScript

When this executes the beforeSend function above is called and the AntiForgeryToken is automatically added to the request headers.

$.ajax({
  type: "POST",
  url: "CSRFProtectedMethod",
  dataType: "json",
  contentType: "application/json; charset=utf-8",
  success: function (data) {
    //victory
  }
});

Server Library

A custom attribute is required to process the non standard token. This builds on @viggity's solution, but handles unobtrusive ajax correctly. This code can be tucked away in your common library

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class ValidateAntiForgeryTokenOnAllPosts : AuthorizeAttribute
{
    public const string HTTP_HEADER_NAME = "x-RequestVerificationToken";

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        var request = filterContext.HttpContext.Request;

        //  Only validate POSTs
        if (request.HttpMethod == WebRequestMethods.Http.Post)
        {

            var headerTokenValue = request.Headers[HTTP_HEADER_NAME];

            // Ajax POSTs using jquery have a header set that defines the token.
            // However using unobtrusive ajax the token is still submitted normally in the form.
            // if the header is present then use it, else fall back to processing the form like normal
            if (headerTokenValue != null)
            {
                var antiForgeryCookie = request.Cookies[AntiForgeryConfig.CookieName];

                var cookieValue = antiForgeryCookie != null
                    ? antiForgeryCookie.Value
                    : null;

                AntiForgery.Validate(cookieValue, headerTokenValue);
            }
            else
            {
                new ValidateAntiForgeryTokenAttribute()
                    .OnAuthorization(filterContext);
            }
        }
    }
}

Server / Controller

Now you just apply the attribute to your Action. Even better you can apply the attribute to your controller and all requests will be validated.

[HttpPost]
[ValidateAntiForgeryTokenOnAllPosts]
public virtual ActionResult CSRFProtectedMethod()
{
  return Json(true, JsonRequestBehavior.DenyGet);
}

To complete previous answers, you can also use Wait-Job to wait for all jobs to complete:

For ($i=1; $i -le 3; $i++) {
    $ScriptBlock = {
        Param (
            [string] [Parameter(Mandatory=$true)] $increment
        )

        Write-Host $increment
    }

    Start-Job $ScriptBlock -ArgumentList $i
}

Get-Job | Wait-Job | Receive-Job

If you're using jQuery and want to keep using indexOf without worrying about compatibility issues, you can do this :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(val) {
        return jQuery.inArray(val, this);
    };
}

This is helpful when you want to keep using indexOf but provide a fallback when it's not available.

I think you're x86-64 install does not have the i386 runtime linker. The ENOENT is probably due to the OS looking for something like /lib/ld.so.1 or similar. This is typically part of the 32-bit glibc runtime, and while I'm not directly familiar with Ubuntu, I would assume they have some sort of 32-bit compatibility package to install. Fortunately gzip only depends on the C library, so that's probably all you'll need to install.

LINQ-to-SQL is a remarkable piece of technology that is very simple to use, and by and large generates very good queries to the back end. LINQ-to-EF was slated to supplant it, but historically has been extremely clunky to use and generated far inferior SQL. I don't know the current state of affairs, but Microsoft promised to migrate all the goodness of L2S into L2EF, so maybe it's all better now.

Personally, I have a passionate dislike of ORM tools (see my diatribe here for the details), and so I see no reason to favour L2EF, since L2S gives me all I ever expect to need from a data access layer. In fact, I even think that L2S features such as hand-crafted mappings and inheritance modeling add completely unnecessary complexity. But that's just me. ;-)

You could probably use the PyPNG package's png.Reader object to do this - decode the base64 string into a regular string (via the base64 standard library), and pass it to the constructor.

As referred to in the first answer, there are 32/64 bit scenarios which introduce build and runtime pitfalls for developers.

The solution is always to try to get right: What kind of software and OS you have installed.

For a small list of scenarios with the Oracle driver and the solution, you can visit this post.

You can also try adding the Motumedia PPA to your apt sources and update your ffmpeg packages.

You can encode it in PHP :)

<img src="data:image/gif;base64,<?php echo base64_encode(file_get_contents("feed-icon.gif")); ?>">

Or display in our dynamic CSS.php file:

background: url("data:image/gif;base64,<?php echo base64_encode(file_get_contents("feed-icon.gif")); ?>");

1 That’s sort of a “quick-n-dirty” technique but it works. Here is another encoding method using fopen() instead of file_get_contents():

<?php // convert image to dataURL
$img_source = "feed-icon.gif"; // image path/name
$img_binary = fread(fopen($img_source, "r"), filesize($img_source));
$img_string = base64_encode($img_binary);
?>

Source

Both Oracle Data Provider for .NET (from Oracle) and .NET Framework Data Provider for Oracle (from Microsoft) require Oracle Client installed on machine.

Does the IIS/IWAM user have permissions on the Oracle directory? Can you connect to this data source using another app, such as Excel or Access?

First, I would like to clarify something. Is this a post back (trip back to server) never occur, or is it the post back occurs, but it never gets into the ddlCountry_SelectedIndexChanged event handler?

I am not sure which case you are having, but if it is the second case, I can offer some suggestion. If it is the first case, then the following is FYI.

For the second case (event handler never fires even though request made), you may want to try the following suggestions:

1. Query the Request.Params[ddlCountries.UniqueID] and see if it has value. If it has, manually fire the event handler.
2. As long as view state is on, only bind the list data when it is not a post back.
3. If view state has to be off, then put the list data bind in OnInit instead of OnLoad.

Beware that when calling Control.DataBind(), view state and post back information would no longer be available from the control. In the case of view state is on, between post back, values of the DropDownList would be kept intact (the list does not to be rebound). If you issue another DataBind in OnLoad, it would clear out its view state data, and the SelectedIndexChanged event would never be fired.

In the case of view state is turned off, you have no choice but to rebind the list every time. When a post back occurs, there are internal ASP.NET calls to populate the value from Request.Params to the appropriate controls, and I suspect happen at the time between OnInit and OnLoad. In this case, restoring the list values in OnInit will enable the system to fire events correctly.

Thanks for your time reading this, and welcome everyone to correct if I am wrong.

None of the above worked for me. I finally solved this problem by renaming favicon.ico to myicon.ico, and reference it in the head <link rel="icon" href="~/myicon.ico" type="image/x-icon" />

The article previously mentioned is good. http://forums.oracle.com/forums/thread.jspa?threadID=191750 (as far as it goes)

If this is not something that runs frequently (don't do it on your home page), you can turn off connection pooling.

There is one other "gotcha" that is not mentioned in the article. If the first thing you try to do with the connection is call a stored procedure, ODP will HANG!!!! You will not get back an error condition to manage, just a full bore HANG! The only way to fix it is to turn OFF connection pooling. Once we did that, all issues went away.

Pooling is good in some situations, but at the cost of increased complexity around the first statement of every connection.

If the error handling approach is so good, why don't they make it an option for ODP to handle it for us????

My issue was that I forgot to put the .hbm in the name of the mapping xml. Also make sure you make it an embedded resource!

You will not able to convert it into data frame until you use implicit conversion.

val sqlContext = new SqlContext(new SparkContext())

import sqlContext.implicits._

After this only you can convert this to data frame

case class Test(id:String,filed2:String)

val myFile = sc.textFile("file.txt")

val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()

Try This

Instead of creating a thread, and using runOnUIThread, this is a perfect job for ASyncTask:

• In onPreExecute, create & show the dialog.

• in doInBackground prepare the data, but don't touch the UI -- store each prepared datum in a field, then call publishProgress.

• In onProgressUpdate read the datum field & make the appropriate change/addition to the UI.

• In onPostExecute dismiss the dialog.

If you have other reasons to want a thread, or are adding UI-touching logic to an existing thread, then do a similar technique to what I describe, to run on UI thread only for brief periods, using runOnUIThread for each UI step. In this case, you will store each datum in a local final variable (or in a field of your class), and then use it within a runOnUIThread block.

You need to use css. It's how modern web design gets things done.

This is a basic css walk through.

Your html file would be like:

(really simple html)

    <html>
    <head>
    <link rel="stylesheet" type="text/css" href="mystyle.css" />
    </head>
    <body>
    </body>
    <html>

Your css file (mystyle.css) would look like:

body 
{
 margin-top:0px;
 margin-left:0px;
 margin-right:0px;

}

Swift 5

    let attrStri = NSMutableAttributedString.init(string:"This is red")
    let nsRange = NSString(string: "This is red").range(of: "red", options: String.CompareOptions.caseInsensitive)
    attrStri.addAttributes([NSAttributedString.Key.foregroundColor : UIColor.red, NSAttributedString.Key.font: UIFont.init(name: "PTSans-Regular", size: 15.0) as Any], range: nsRange)
    self.label.attributedText = attrStri

you can't. foo-bar is not an identifier. rename the file to foo_bar.py

Edit: If import is not your goal (as in: you don't care what happens with sys.modules, you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile

# contents of foo-bar.py
baz = 'quux'

>>> execfile('foo-bar.py')
>>> baz
'quux'
>>> 

You have to use UPDATE instead of INSERT:

• UPDATE Syntax

For Example:

UPDATE table1 SET col_a='k1', col_b='foo' WHERE key_col='1';
UPDATE table1 SET col_a='k2', col_b='bar' WHERE key_col='2';

When you assign a function to a variable you don't use the () but simply the name of the function.

In your case given def x(): ..., and variable silly_var you would do something like this:

silly_var = x

and then you can call the function either with

x()

or

silly_var()

You can do something like the following. In this case you are using the lock on a and b to synchronized instead of the lock on "this". We cannot use int because primitive values don't have locks, so we use Integer.

class x{
   private Integer a;
   private Integer b;
   public void addA(){
      synchronized(a) {
         a++;
      }
   }
   public synchronized void addB(){
      synchronized(b) {
         b++;
      }
   }
}

Very old question, but I've written some example just for fun — maybe you'll find it useful ;)

#import "InitAllocNewTest.h"

@implementation InitAllocNewTest

+(id)alloc{
    NSLog(@"Allocating...");
    return [super alloc];
}

-(id)init{
    NSLog(@"Initializing...");
    return [super init];
}

@end

In main function both statements:

[[InitAllocNewTest alloc] init];

and

[InitAllocNewTest new];

result in the same output:

2013-03-06 16:45:44.125 XMLTest[18370:207] Allocating...
2013-03-06 16:45:44.128 XMLTest[18370:207] Initializing...

This should do it

replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}

with open('path/to/input/file') as infile, open('path/to/output/file', 'w') as outfile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        outfile.write(line)

EDIT: To address Eildosa's comment, if you wanted to do this without writing to another file, then you'll end up having to read your entire source file into memory:

lines = []
with open('path/to/input/file') as infile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        lines.append(line)
with open('path/to/input/file', 'w') as outfile:
    for line in lines:
        outfile.write(line)

Edit: If you are using Python 3.x, use replacements.items() instead of replacements.iteritems()

Add a $event to the ng-click, for example:

<button type="button" ng-click="saveOffer($event)" accesskey="S"></button>

Then the jQuery.Event was passed to the callback:

merge to Map

 let merge = {...map1,...map2};

I seem to find the trick: Just remove the form target attribute, then use a submit button to validate the form and show hints, check if form valid via JavaScript, and then post whatever. The following code works for me:

<form>
  <input name="foo" required>
  <button id="submit">Submit</button>
</form>

<script>
$('#submit').click( function(e){
  var isValid = true;
  $('form input').map(function() {
    isValid &= this.validity['valid'] ;
  }) ;
  if (isValid) {
    console.log('valid!');
    // post something..
  } else
    console.log('not valid!');
});
</script>

Try this approach using the newer str.format syntax:

line_new = '{:>12}  {:>12}  {:>12}'.format(word[0], word[1], word[2])

And here's how to do it using the old % syntax (useful for older versions of Python that don't support str.format):

line_new = '%12s  %12s  %12s' % (word[0], word[1], word[2])

Bitcode is a new feature of iOS 9

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Note: For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required

So you should disabled bitcode until all the frameworks of your app have bitcode enabled.

When call add_subparsers method save the first positional argument to dest= and check value after argparse has been initialized, like this:

subparsers = parser.add_subparsers(dest='command')

And just check this this variable:

if not args.command:
    parser.print_help()
    parser.exit(1)  # If exit() - exit code will be zero (no error)

Full example:

#!/usr/bin/env python

""" doc """

import argparse
import sys

parser = argparse.ArgumentParser(description=__doc__)
subparsers = parser.add_subparsers(dest='command',
                                   help='List of commands')

list_parser = subparsers.add_parser('list',
                                    help='List contents')
list_parser.add_argument('dir', action='store',
                         help='Directory to list')

create_parser = subparsers.add_parser('create',
                                      help='Create a directory')
create_parser.add_argument('dirname', action='store',
                           help='New directory to create')
create_parser.add_argument('--read-only', default=False, action='store_true',
                           help='Set permissions to prevent writing to the directory')

args = parser.parse_args()

if not args.command:
    parser.print_help()
    parser.exit(1)

print(vars(args))  # For debug

Use the datetime method and the operator < and its kin.

>>> from datetime import datetime, timedelta
>>> past = datetime.now() - timedelta(days=1)
>>> present = datetime.now()
>>> past < present
True
>>> datetime(3000, 1, 1) < present
False
>>> present - datetime(2000, 4, 4)
datetime.timedelta(4242, 75703, 762105)

(a) wwww.somewebsite.com/a.txt isn't a 'file URL'. It isn't a URL at all. If you put http:// on the front of it it would be an HTTP URL, which is clearly what you intend here.

(b) FileInputStream is for files, not URLs.

(c) The way to get an input stream from any URL is via URL.openStream(), or URL.getConnection().getInputStream(), which is equivalent but you might have other reasons to get the URLConnection and play with it first.

This works for me to access the class attribute (on beautifulsoup 4, contrary to what the documentation says). The KeyError comes a list being returned not a dictionary.

for hit in soup.findAll(name='span'):
    print hit.contents[1]['class']

Because the < operator (and most others) are binary operators (they take two arguments), and (true true) is not a valid boolean expression.

The Java language designers could have designed the language to allow syntax like the type you prefer, but (I'm guessing) they decided that it was not worth the more complex parsing rules.

If you run your playbook with ansible-playbook -vvv you'll see the actual command being run, so you can check whether the key is actually being included in the ssh command (and you might discover that the problem was the wrong username rather than the missing key).

I agree with Brian's comment above (and zigam's edit) that the vars section is too late. I also tested including the key in the on-the-fly definition of the host like this

# fails
- name: Add all instance public IPs to host group
  add_host: hostname={{ item.public_ip }} groups=ec2hosts ansible_ssh_private_key_file=~/.aws/dev_staging.pem
  loop: "{{ ec2.instances }}"

but that fails too.

So this is not an answer. Just some debugging help and things not to try.

You can use the DATEDIFF function to get the difference in minutes, seconds, days etc.

SELECT DATEDIFF(MINUTE,job_start,job_end)

MINUTE obviously returns the difference in minutes, you can also use DAY, HOUR, SECOND, YEAR (see the books online link for the full list).

If you want to get fancy you can show this differently for example 75 minutes could be displayed like this: 01:15:00:0

Here is the code to do that for both SQL Server 2005 and 2008

-- SQL Server 2005
SELECT CONVERT(VARCHAR(10),DATEADD(MINUTE,DATEDIFF(MINUTE,job_start,job_end),'2011-01-01 00:00:00.000'),114)

-- SQL Server 2008
SELECT CAST(DATEADD(MINUTE,DATEDIFF(MINUTE,job_start,job_end),'2011-01-01 00:00:00.000') AS TIME)

Concerning the answer by BoltClock and John, I personally had issues with the initial keyword when using IE11. It works fine in Chrome, but in IE it seems to have no effect.

According to this answer IE does not support the initial keyword: Div display:initial not working as intended in ie10 and chrome 29

I tried setting it blank instead as suggested here: how to revert back to normal after display:none for table row

This worked and was good enough for my scenario. Of course to set the real initial value the above answer is the only good one I could find.

Using Java 7:

Paths.get(string).toUri().toURL();

However, you probably want to get a URI. Eg, a URI begins with file:/// but a URL with file:/ (at least, that's what toString produces).

Its blank because you are writing to file. you should write to output using php://output instead and also send header information to indicate that it's csv.

Example

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
        'aaa,bbb,ccc,dddd',
        '123,456,789',
        '"aaa","bbb"'
);

$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
    $val = explode(",", $line);
    fputcsv($fp, $val);
}
fclose($fp);

This is the correct way:

You should declare the length of the array after "="

Veicle[] cars = new Veicle[N];

Please Note: The following answer only applied to WPF under the 3.5 Framework as NET 4.0 runtime has it's own datetime control.

By default WPF 3.5 does not come with a date time picker like winforms.

However a date picker has been added in the WPF tool kit produced by Microsoft which can be downloaded here. I guess it will become part of the framework in a future release.

It is simple to add a reference to the WPFToolkit.dll, see it in the tool box and distribute with your application by following the instructions on the website.

Before this was available other people had created 3rd party pickers (which you may prefer) or alternatively used the less ideal solution of using the winforms control in a WPF application.

Update: This so question is very similar this one which also has a link to a walk through for the datepicker along with other links.

As Matt J wrote, there is itoa, but it's not standard. Your code will be more portable if you use snprintf.

Maybe you can try this: though please note - This pulls the column count, not the row count

 using (SqlDataReader reader = command.ExecuteReader())
 {
     while (reader.Read())
     {
         int count = reader.VisibleFieldCount;
         Console.WriteLine(count);
     }
 }

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

• Spring is a lightweight and flexible framework compare to J2EE.
• Spring container act as a inversion of control.
• Spring uses AOP i.e. proxies and Singleton, Factory and Template Method Design patterns.
• Tiered architectures: Separation of concerns and Reusable layers and Easy maintenance.

I also encountered this on OS X after updating OS X v10.9 (Mavericks), when the old Java 6 was being used and tried to access an HTTPS URL. The fix was the inverse of Peter Kriens; I needed to copy the cacerts from the 1.7 space to the location linked by the 1.6 version:

(as root)
umask 022
mkdir -p /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security
cp $(/usr/libexec/java_home -v 1.7)/jre/lib/security/cacerts \
    /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security

An enhancement to MC ND's answer for Windows.
I needed a script to run in WinPE, so I did the following:

@echo off
SET TARGET=192.168.1.1
IF "%~1" NEQ "" SET TARGET=%~1

ping -t %TARGET%|cmd /q /v /c "(pause&pause)>nul & for /l %%a in () do (set /p "data=" && echo(!time! !data!)&ping -n 2 localhost >nul"

This can be hardcoded to a particular IP Address (192.168.1.1 in my example) or take a passed parameter. And as in MC ND's answer, repeats the ping about every 1 second.

This isn't exactly the issue I had, but if anyone is looking to convert a BindingList of any type to List of the same type, then this is how it is done:

var list = bindingList.ToDynamicList();

Also, if you're assigning BindingLists of dynamic types to a DataGridView.DataSource, then make sure you declare it first as IBindingList so the above works.

You can use the class selector along with descendant selector

$("#my_id .my_class")

If you are planing to use the list as a fast dictionary accessed many times, then the is.null approach might be the only viable option. I assume it is O(1), while the %in% approach is O(n)?

Not a direct answer, but I've seen many borked prod data situations that could have been avoided by typing the WHERE clause first! Sometimes a WHERE 1 = 0 can help with putting a working statement together safely too. And looking at an estimated execution plan, which will estimate rows affected, can be useful. Beyond that, in a transaction that you roll back as others have said.

You want the following:

ALTER TABLE mytable MODIFY mycolumn VARCHAR(255);

Columns are nullable by default. As long as the column is not declared UNIQUE or NOT NULL, there shouldn't be any problems.

First we need to plan how the application will render differently in different locals. Here it shows example, where the text string and images have to go.

fr-rFR French / France res/values-fr/ res/drawable-fr-rFR/

Every answer refering to SuppressWarningsFilter is missing an important detail. You can only use the all-lowercase id if it's defined as such in your checkstyle-config.xml. If not you must use the original module name.

For instance, if in my checkstyle-config.xml I have:

<module name="NoWhitespaceBefore"/>

I cannot use:

@SuppressWarnings({"nowhitespacebefore"})

I must, however, use:

@SuppressWarnings({"NoWhitespaceBefore"})

In order for the first syntax to work, the checkstyle-config.xml should have:

<module name="NoWhitespaceBefore">
  <property name="id" value="nowhitespacebefore"/>
</module>

This is what worked for me, at least in the CheckStyle version 6.17.

Double underscore. That mangles the name. The variable can still be accessed, but it's generally a bad idea to do so.

Use single underscores for semi-private (tells python developers "only change this if you absolutely must") and doubles for fully private.

Use Integer.parseInt (see javadoc), that converts your String to int using base two:

int decimalValue = Integer.parseInt(c, 2);

This worked with me: Eclipse will not open due to environment variables

Let eclipse use your java vm directly!

Put these lines at the end of eclipse.ini (located in the directory where eclipse.exe is present):

-vm
<your path to jdk|jre>/bin/javaw.exe

Pay attention that there are two lines. Also make sure that the -vm option is before the -vmargs option (and of course after "openFile").

When ever you require to communicate between child to parent at any level down, then it's better to make use of context. In parent component define the context that can be invoked by the child such as

In parent component in your case component 3

static childContextTypes = {
        parentMethod: React.PropTypes.func.isRequired
      };

       getChildContext() {
        return {
          parentMethod: (parameter_from_child) => this.parentMethod(parameter_from_child)
        };
      }

parentMethod(parameter_from_child){
// update the state with parameter_from_child
}

Now in child component (component 5 in your case) , just tell this component that it want to use context of its parent.

 static contextTypes = {
       parentMethod: React.PropTypes.func.isRequired
     };
render(){
    return(
      <TouchableHighlight
        onPress={() =>this.context.parentMethod(new_state_value)}
         underlayColor='gray' >   

            <Text> update state in parent component </Text>              

      </TouchableHighlight>
)}

The SignTool is available as part of the Windows SDK (which comes with Visual Studio Community 2015). Make sure to select the "ClickOnce Publishing Tools" from the feature list during the installation of Visual Studio 2015 to get the SignTool.

Once Visual Studio is installed you can run the signtool command from the Visual Studio Command Prompt. By default (on Windows 10) the SignTool will be installed at C:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe.

If you mean you are only getting a null return when you use NUnit, then you probably need to copy the ConnectionString value the your app.config of your application to the app.config of your test library.

When it is run by the test loader, the test assembly is loaded at runtime and will look in its own app.config (renamed to testAssembly.dll.config at compile time) rather then your applications config file.

To get the location of the assembly you're running, try

System.Reflection.Assembly.GetExecutingAssembly().Location

Alternatively to Martin's answer, you could also add the INTO part at the end of the query to make the query more readable:

SELECT Id, dateCreated FROM products INTO iId, dCreate

Simple, you just open klik file -> import -> General -> existing project into workspace -> browse file in your directory.

I agree with most of the answers.

You should not depend fully on either finalize or ShutdownHook

finalize

1. The JVM does not guarantee when this finalize() method will be invoked.

2. finalize() gets called only once by GC thread. If an object revives itself from finalizing method, then finalize will not be called again.

3. In your application, you may have some live objects, on which garbage collection is never invoked.

4. Any Exception that is thrown by the finalizing method is ignored by the GC thread

5. System.runFinalization(true) and Runtime.getRuntime().runFinalization(true) methods increase the probability of invoking finalize() method but now these two methods have been deprecated. These methods are very dangerous due to lack of thread safety and possible deadlock creation.

shutdownHooks

public void addShutdownHook(Thread hook)

Registers a new virtual-machine shutdown hook.

The Java virtual machine shuts down in response to two kinds of events:

1. The program exits normally, when the last non-daemon thread exits or when the exit (equivalently, System.exit) method is invoked, or

2. The virtual machine is terminated in response to a user interrupt, such as typing ^C, or a system-wide event, such as user logoff or system shutdown.

3. A shutdown hook is simply an initialized but non-started thread. When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled.

4. Finally, the virtual machine will halt. Note that daemon threads will continue to run during the shutdown sequence, as will non-daemon threads if the shutdown was initiated by invoking the exit method.

5. Shutdown hooks should also finish their work quickly. When a program invokes exit the expectation is that the virtual machine will promptly shut down and exit.

   But even Oracle documentation quoted that

In rare circumstances the virtual machine may abort, that is, stop running without shutting down cleanly

This occurs when the virtual machine is terminated externally, for example with the SIGKILL signal on Unix or the TerminateProcess call on Microsoft Windows. The virtual machine may also abort if a native method goes awry by, for example, corrupting internal data structures or attempting to access nonexistent memory. If the virtual machine aborts then no guarantee can be made about whether or not any shutdown hooks will be run.

Conclusion : use try{} catch{} finally{} blocks appropriately and release critical resources in finally(} block. During release of resources in finally{} block, catch Exception and Throwable.

Just a remark about your saying

Hi, I tried searching a way to insert information in multiple tables in the same query

Do you eat all your lunch dishes mixed with drinks in the same bowl?
I suppose - no.

Same here.
There are things we do separately.
2 insert queries are 2 insert queries. It's all right. Nothing wrong with it. No need to mash it in one.
Same for select. Query must be sensible and do it's job. That's the only reasons. Number of queries is not.

As for the transactions - you may use them, but it's not THAT big deal for the average web-site. If it happened once a year (if ever) that one user registration being broken you'll be able to fix, no doubt.
there are hundreds of thousands sites running mysql with no transaction support driver. Have you heard of terrible disasters breaking these sites apart? Me neither.

And mysql_insert_id() has noting to do with transactions. you may include in into transaction all right. it's just different matters. Someone raised this question out of nowhere.

Use:

if(comboBox.SelectedIndex > -1) //somthing was selected

To get the selected item you do:

Item m = comboBox.Items[comboBox.SelectedIndex];

As Matthew correctly states, to get the selected item you could also do

Item m = comboBox.SelectedItem;

The following worked and the images to be set is resources in properties:

    var bitmapSource = Imaging.CreateBitmapSourceFromHBitmap(MyProject.Properties.Resources.myImage.GetHbitmap(),
                                      IntPtr.Zero,
                                      Int32Rect.Empty,
                                      BitmapSizeOptions.FromEmptyOptions());
    MyButton.Background = new ImageBrush(bitmapSource);
img_username.Source = bitmapSource;

The standard Web Storage, does not say anything about the restoring any of these. So there won't be any standard way to do it. You have to go through the way the browsers implement these, or find a way to backup these before you delete them.

Do you want to look for strings that include an escape character? For instance you want this:

select * from table where myfield like '%10%%'.

Where you want to search for all fields with 10%? If that is the case then you may use the ESCAPE clause to specify an escape character and escape the wildcard character.

select * from table where myfield like '%10!%%' ESCAPE '!'

I used this at the end of the web.php or api.php file and it worked perfectly:

URL::forceScheme('https');

There are a couple different ways I would do this:

1) Mimic Excel Tables Using with a Named Range

In your example, you named the range A10:A20 "Age". Depending on how you wanted to reference a cell in that range you could either (as @Alex P wrote) use =INDEX(Age, 5) or if you want to reference a cell in range "Age" that is on the same row as your formula, just use:

=INDEX(Age, ROW()-ROW(Age)+1)

This mimics the relative reference features built into Excel tables but is an alternative if you don't want to use a table.

If the named range is an entire column, the formula simplifies as:

=INDEX(Age, ROW())

2) Use an Excel Table

Alternatively if you set this up as an Excel table and type "Age" as the header title of the Age column, then your formula in columns to the right of the Age column can use a formula like this:

=[@[Age]]

We recently upgraded to the NuGet version of SqlClient (Microsoft.Data.SqlClient) which contains a bug. This bug was introduced during the lifetime of the 1.x cycle and has already been fixed. The fix will be available in the 2.0.0 release which is not available at the time of this writing. A preview is available.

You can inspect the details here: https://github.com/dotnet/SqlClient/issues/262

Lazy loading - is good when handling with pagination like on page load list of users appear which contains 10 users and as the user scrolls down the page an api call brings next 10 users.Its good when you don't want to load enitire data at once as it would take more time and would give bad user experience.

Eager loading - is good as other people suggested when there are not much relations and fetch entire data at once in single call to database

If the only thing you want to do is drop in an image onto a widget withouth the complexity of the graphics API, you can also just create a new QWidget and set the background with StyleSheets. Something like this:

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
    ...
    QWidget *pic = new QWidget(this);
    pic->setStyleSheet("background-image: url(test.png)");
    pic->setGeometry(QRect(50,50,128,128));
    ...
}

You can remove elements from ArrayList using ListIterator,

ListIterator listIterator = List_Of_Array.listIterator();

 /* Use void remove() method of ListIterator to remove an element from List.
     It removes the last element returned by next or previous methods.
 */
listIterator.next();

//remove element returned by last next method
listIterator.remove();//remove element at 1st position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 3rd position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 5th position

USE this i hope help you

var interval;

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            /* clearInterval(interval); */
            stopinterval(); // stop the interval
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
        }
    });
}

function playinterval(){
  updateDiv(); 
  interval = setInterval(function(){updateDiv();},3000); 
  return false;
}

function stopinterval(){
  clearInterval(interval); 
  return false;
}

$(document)
.on('ready',playinterval)
.on({click:playinterval},"#playinterval")
.on({click:stopinterval},"#stopinterval");

I had exactly the same issue and had been struggling for a while then finally found the solution which is to set -a parameter to the sqlcmd in order to change its default packet size:

sqlcmd -S [servername] -d [databasename] -i [scriptfilename] -a 32767

One of the approaches may be like this:

1) Create a CSS file with name "style.css" and define an id selector in it:

#pane{
    -fx-background-image: url("background_image.jpg");
    -fx-background-repeat: stretch;   
    -fx-background-size: 900 506;
    -fx-background-position: center center;
    -fx-effect: dropshadow(three-pass-box, black, 30, 0.5, 0, 0); 
}

2) Set the id of the most top control (or any control) in the scene with value defined in CSS and load this CSS file into the scene:

  public class Test extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        StackPane root = new StackPane();
        root.setId("pane");
        Scene scene = new Scene(root, 300, 250);
        scene.getStylesheets().addAll(this.getClass().getResource("style.css").toExternalForm());
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

You can also give an id to the control in a FXML file:

<StackPane id="pane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml" fx:controller="demo.Sample">
    <children>
    </children>
</StackPane>

For more info about JavaFX CSS Styling refer to this guide.

StringBuilder sb = new StringBuilder();
for(int i=0;i<100;i++){
    sb.insert(0, Integer.toString(i));
}

Warning: It defeats the purpose of StringBuilder, but it does what you asked.

Better technique (although still not ideal):

1. Reverse each string you want to insert.
2. Append each string to a StringBuilder.
3. Reverse the entire StringBuilder when you're done.

This will turn an O(n²) solution into O(n).

i was looking for the same and found the answer,

solution is to use the styled map, on below link you can create your custom styles through wizard and test is at the same time google map style wizard

you can check all available options : here

here is my sample code which creates boundary for states and hide all the road and there labels.

    var styles = [
  {
    "featureType": "administrative.province",
    "elementType": "geometry.stroke",
    "stylers": [
      { "visibility": "on" },
      { "weight": 2.5 },
      { "color": "#24b0e2" }
    ]
  },{
    "featureType": "road",
    "elementType": "geometry",
    "stylers": [
      { "visibility": "off" }
    ]
  },{
    "featureType": "administrative.locality",
    "stylers": [
      { "visibility": "off" }
    ]
  },{
    "featureType": "road",
    "elementType": "labels",
    "stylers": [
      { "visibility": "off" }
    ]
  }
];

  var  geocoder = new google.maps.Geocoder();
   geocoder.geocode({
       'address': "rajasthan"
   }, (results, status)=> {
     var mapOpts = {
       mapTypeId: google.maps.MapTypeId.ROADMAP,
       scaleControl: true,
       scrollwheel: false,
       styles:styles,
       center: results[0].geometry.location,
       zoom:6
     }
     map = new google.maps.Map(document.getElementById("map"), mapOpts);
   });

The below code helps me:

 {{ request.build_absolute_uri }}

You can use the following to only include valid characters:

SQL

SELECT * FROM @Table
WHERE Col NOT LIKE '%[^0-9.]%'

Results

Col

Node* insert_node_at_nth_pos(Node *head, int data, int position)
{   
    /* current node */
    Node* cur = head;

    /* initialize new node to be inserted at given position */
    Node* nth = new Node;
    nth->data = data;
    nth->next = NULL;

    if(position == 0){
        /* insert new node at head */
        head = nth;
        head->next = cur;
        return head;
    }else{
        /* traverse list */
        int count = 0;            
        Node* pre = new Node;

        while(count != position){
            if(count == (position - 1)){
                pre = cur;
            }
            cur = cur->next;            
            count++;
        }

        /* insert new node here */
        pre->next = nth;
        nth->next = cur;

        return head;
    }    
}

here is my two cents. In comparisson to other solutions, one does not need to add extra containers. Therefor this solution is a bit more elegant. Beneath the code example i'll explain why this works.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>test</title>
        <style>

            html
            {
                height:100%;
            }

            body
            {
                min-height:100%;
                padding:0; /*not needed, but otherwise header and footer tags have padding and margin*/
                margin:0; /*see above comment*/
            }

            body
            {
                position:relative;
                padding-bottom:60px; /* Same height as the footer. */           
            }

            footer
            {
                position:absolute;
                bottom:0px;
                height: 60px;

                background-color: red;
            }

        </style>
    </head>
    <body>
        <header>header</header>


        <footer>footer</footer>
    </body>
</html>

So the first thing we do, is make the biggest container( html ) 100%. The html page is as big as the page itself. Next we set the body height, it can be bigger than the 100% of the html tag, but it should at least be as big, therefore we use min-height 100%.

We also make the body relative. Relative means you can move the block element around relative from its original position. We don't use that here though. Because relative has a second use. Any absolute element is either absolute to the root (html) or to the first relative parent/grandparent. That's what we want, we want the footer to be absolute, relative to the body, namely the bottom.

The last step is to set the footer to absolute and bottom:0, which moves it to the bottom of the first parent/grandparent that is relative ( body ofcourse ).

Now we still have one problem to fix, when we fill the complete page, the content goes beneath the footer. Why? well, because the footer is no longer inside the "html flow", because it is absolute. So how do we fix this? We will add padding-bottom to the body. This makes sure the body is actually bigger than it's content.

I hope i made a lot clear for you guys.

The code you have at the moment seems to be all right. Check what the checkboxes array contains using this. Add this code on the top of your php script and see whether the checkboxes are being passed to your script.

echo '<pre>'.print_r($_POST['myCheckboxes'], true).'</pre>';
exit;

I had the same issue i resolved it by repairing the iis server in programs and features.

GO TO

Controll panel > uninstall a program and then right click the installed iis express server (installed with Visual Studio) and then click repair.

this is how i solved this issue

Here is the Jquery Code

$(document).ready(function () {
     var el = $('#Container');
        var originalelpos = el.offset().top; // take it where it originally is on the page

        //run on scroll
        $(window).scroll(function () {
            var el = $('#Container'); // important! (local)
            var elpos = el.offset().top; // take current situation
            var windowpos = $(window).scrollTop();
            var finaldestination = windowpos + originalelpos;
            el.stop().animate({ 'top': finaldestination }, 1000);
        });
    });

I could not find a standard control and had 0 intention to use a library such as bootstrap select so I custom made this widget. Bootstrap 4 allows you to add forms inside your dropdown which is what I have used here. I added a search box, used an input event to capture the text entered by the user inside the box, If the phrase entered by the user starts with the items inside the box, I show the items else I hide them. I also handle the click event on any item to change the text of the dropdown button

UPDATE 1

The code above uses show() and hide() inside a loop which is why the UI is slow when you clear everything you typed in case you didn't notice. Instead of that, use .css({display: 'none'}) and .css({display: 'block'})

I can't imagine everyone uses all 20 different keypresses to navigate text, 10 or so keys to start adding text, and 18 ways to visually select an inner block. Or do you!?

I do.

In theory, once I have that and start becoming as proficient in VIM as I am in Textmate, then I can start learning the thousands of other VIM commands that will make me more efficient.

That's the right way to do it. Start with basic commands and then pick up ones that improve your productivity. I like following this blog for tips on how to improve my productivity with vim.

It`s definitely better to use COMPOSITE UNIQUE KEY, as @GranadaCoder offered, a little bit tricky example though:

ALTER IGNORE TABLE table_name ADD UNIQUES INDEX idx_name(some_id, another_id, one_more_id);

On top of @unutbu answer, you could coerce pandas numpy object array to native (float64) type, something along the line

import pandas as pd
pd.to_numeric(df['tester'], errors='coerce')

Specify errors='coerce' to force strings that can't be parsed to a numeric value to become NaN. Column type would be dtype: float64, and then isnan check should work

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

now, for dplyr, adding a distinct counter.

df %>%
    group_by(aa, bb) %>%
    summarise(first=head(value,1), count=n_distinct(value))

You create groups, them summarise within groups.

If data is numeric, you can use:
first(value) [there is also last(value)] in place of head(value, 1)

Simple method:

public boolean isBlank(String value) {
    return (value == null || value.equals("") || value.equals("null") || value.trim().equals(""));
}

public String normalizeOnlyLettersNumbers(String str) {
    if (!isBlank(str)) {
        return str.replaceAll("[^\\p{L}\\p{Nd}]+", "");
    } else {
        return "";
    }
}

Peter Lawrey's answer is great because it is simple and not depending on anything special, and it's the way you should do it. If you need something that removes subdirectories and their contents as well, use recursion:

void purgeDirectory(File dir) {
    for (File file: dir.listFiles()) {
        if (file.isDirectory())
            purgeDirectory(file);
        file.delete();
    }
}

To spare subdirectories and their contents (part of your question), modify as follows:

void purgeDirectoryButKeepSubDirectories(File dir) {
    for (File file: dir.listFiles()) {
        if (!file.isDirectory())
            file.delete();
    }
}

Or, since you wanted a one-line solution:

for (File file: dir.listFiles())
    if (!file.isDirectory())
        file.delete();

Using an external library for such a trivial task is not a good idea unless you need this library for something else anyway, in which case it is preferrable to use existing code. You appear to be using the Apache library anyway so use its FileUtils.cleanDirectory() method.

try this

    SELECT id FROM events WHERE start BETWEEN '2013-06-13' AND '2013-07-22' 
                          AND   end   BETWEEN '2013-06-13' AND '2013-07-22'

output :

Yes you can connect your android app to your PHP to grab results from your database. Use a webservice to connect to your backend script via ASYNC task and http post requests. Check this link for more information Connecting to MySQL

Subclass is to Class as Java is to Programming Language.

A previous answer is mostly correct, but it will also match the empty string. The following would solve this.

^([0-9]?[0-9](\.[0-9][0-9]?)?)|([0-9]?[0-9]?(\.[0-9][0-9]?))$

On EF6.2, you can use HasIndex() to add indexes for migration through fluent API.

https://github.com/aspnet/EntityFramework6/issues/274

Example

modelBuilder
    .Entity<User>()
    .HasIndex(u => u.Email)
        .IsUnique();

On EF6.1 onwards, you can use IndexAnnotation() to add indexes for migration in your fluent API.

http://msdn.microsoft.com/en-us/data/jj591617.aspx#PropertyIndex

You must add reference to:

using System.Data.Entity.Infrastructure.Annotations;

Basic Example

Here is a simple usage, adding an index on the User.FirstName property

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .HasColumnAnnotation(IndexAnnotation.AnnotationName, new IndexAnnotation(new IndexAttribute()));

Practical Example:

Here is a more realistic example. It adds a unique index on multiple properties: User.FirstName and User.LastName, with an index name "IX_FirstNameLastName"

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .IsRequired()
    .HasMaxLength(60)
    .HasColumnAnnotation(
        IndexAnnotation.AnnotationName, 
        new IndexAnnotation(
            new IndexAttribute("IX_FirstNameLastName", 1) { IsUnique = true }));

modelBuilder 
    .Entity<User>() 
    .Property(t => t.LastName) 
    .IsRequired()
    .HasMaxLength(60)
    .HasColumnAnnotation(
        IndexAnnotation.AnnotationName, 
        new IndexAnnotation(
            new IndexAttribute("IX_FirstNameLastName", 2) { IsUnique = true }));

if you use oldder varsions of ES, (ES5 for example), you can use as any:

for (let element of elementsToIterate as any) {
      console.log(element);
}

You need to create a C API for exposing the functionality of your C++ code. Basically, you will need to write C++ code that is declared extern "C" and that has a pure C API (not using classes, for example) that wraps the C++ library. Then you use the pure C wrapper library that you've created.

Your C API can optionally follow an object-oriented style, even though C is not object-oriented. Ex:

 // *.h file
 // ...
 #ifdef __cplusplus
 #define EXTERNC extern "C"
 #else
 #define EXTERNC
 #endif

 typedef void* mylibrary_mytype_t;

 EXTERNC mylibrary_mytype_t mylibrary_mytype_init();
 EXTERNC void mylibrary_mytype_destroy(mylibrary_mytype_t mytype);
 EXTERNC void mylibrary_mytype_doit(mylibrary_mytype_t self, int param);

 #undef EXTERNC
 // ...


 // *.cpp file
 mylibrary_mytype_t mylibrary_mytype_init() {
   return new MyType;
 }

 void mylibrary_mytype_destroy(mylibrary_mytype_t untyped_ptr) {
    MyType* typed_ptr = static_cast<MyType*>(untyped_ptr);
    delete typed_ptr;
 }

 void mylibrary_mytype_doit(mylibrary_mytype_t untyped_self, int param) {
    MyType* typed_self = static_cast<MyType*>(untyped_self);
    typed_self->doIt(param);
 }

So when you call EntityManager.persist(), it only makes the entity get managed by the EntityManager and adds it (entity instance) to the Persistence Context. An Explicit flush() will make the entity now residing in the Persistence Context to be moved to the database (using a SQL).

Without flush(), this (moving of entity from Persistence Context to the database) will happen when the Transaction to which this Persistence Context is associated is committed.

If you installed brew, cmd below will be helpful:

brew cask install java

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname
... As before

Here is an automated way to do this via a bash script:

host=$1
dbName=$2
user=$3
password=$4

if [ -z "$1" ]
then
    host="localhost"
fi

# drop all the tables in the database
for i in `mysql -h$host -u$user -p$password $dbName -e "show tables" | grep -v Tables_in` ; do  echo $i && mysql -h$host -u$user -p$password $dbName -e "SET FOREIGN_KEY_CHECKS = 0; drop table $i ; SET FOREIGN_KEY_CHECKS = 1" ; done

JSONLint has an open-source implementation on GitHub that can be used on the command line or included in a Node.js project.

npm install jsonlint -g

and then

jsonlint -p myfile.json

or

curl -s "http://api.twitter.com/1/users/show/user.json" | jsonlint | less

borderColor on any view(or UIView Subclass) could also be set using storyboard with a little bit of coding and this approach could be really handy if you're setting border color on multiple UI Objects.

Below are the steps how to achieve it,

1. Create a category on CALayer class. Declare a property of type UIColor with a suitable name, I'll name it as borderUIColor .
2. Write the setter and getter for this property.
3. In the 'Setter' method just set the "borderColor" property of layer to the new colors CGColor value.
4. In the 'Getter' method return UIColor with layer's borderColor.

P.S: Remember, Categories can't have stored properties. 'borderUIColor' is used as a calculated property, just as a reference to achieve what we're focusing on.

Please have a look at the below code sample;

Objective C:

Interface File:

#import <QuartzCore/QuartzCore.h>
#import <UIKit/UIKit.h>

@interface CALayer (BorderProperties)

// This assigns a CGColor to borderColor.
@property (nonatomic, assign) UIColor* borderUIColor;

@end

Implementation File:

#import "CALayer+BorderProperties.h"

@implementation CALayer (BorderProperties)

- (void)setBorderUIColor:(UIColor *)color {
    self.borderColor = color.CGColor;
}

- (UIColor *)borderUIColor {
    return [UIColor colorWithCGColor:self.borderColor];
}

@end

Swift 2.0:

extension CALayer {
var borderUIColor: UIColor {
    set {
        self.borderColor = newValue.CGColor
    }

    get {
        return UIColor(CGColor: self.borderColor!)
    }
}
}

And finally go to your storyboard/XIB, follow the remaining steps;

5. Click on the View object for which you want to set border Color.
6. Click on "Identity Inspector"(3rd from Left) in "Utility"(Right side of the screen) panel.
7. Under "User Defined Runtime Attributes", click on the "+" button to add a key path.
8. Set the type of the key path to "Color".
9. Enter the value for key path as "layer.borderUIColor". [Remember this should be the variable name you declared in category, not borderColor here it's borderUIColor].
10. Finally chose whatever color you want.

You've to set layer.borderWidth property value to at least 1 to see the border color.

Build and Run. Happy Coding. :)

I want to add to other answers that setters can be used to prevent putting the object in an invalid state.

For instance let's suppose that I've to set a TaxId, modelled as a String. The first version of the setter can be as follows:

private String taxId;

public void setTaxId(String taxId) {
    this.taxId = taxId;
}

However we'd better prevent the use to set the object with an invalid taxId, so we can introduce a check:

private String taxId;

public void setTaxId(String taxId) throws IllegalArgumentException {
    if (isTaxIdValid(taxId)) {
        throw new IllegalArgumentException("Tax Id '" + taxId + "' is invalid");
    }
    this.taxId = taxId;
}

The next step, to improve the modularity of the program, is to make the TaxId itself as an Object, able to check itself.

private final TaxId taxId = new TaxId()

public void setTaxId(String taxIdString) throws IllegalArgumentException {
    taxId.set(taxIdString); //will throw exception if not valid
}

Similarly for the getter, what if we don't have a value yet? Maybe we want to have a different path, we could say:

public String getTaxId() throws IllegalStateException {
    return taxId.get(); //will throw exception if not set
}

None of those worked for me. Try this.

console.log($(canvasjQueryElement)[0].width)

It's best to add up the .gitignore list through the development time to prevent unknown side effect when Version Control won't work for some reason because of the pre-defined (copy/paste) list from somewhere. For one of my project, the ignore list is only of:

.gradle
.idea
libs
obj
build
*.log

Tools >> Options >> Designers and uncheck “Prevent Saving changes that require table re-creation”:

  select object_name(c.object_id) as table_name
    , schema_name(t.schema_id) as schema_name
    from sys.columns c
    join sys.tables t on c.object_id = t.object_id
     where c.name=N'CreatedDate';

It gets a little more complicated if you want alsoother table properties, but you'll refer to the object catalog views like sys.tables, sys.columns etc.

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

Heredoc sounds more convenient for this purpose. It is used to send multiple commands to a command interpreter program like ex or cat

cat << EndOfMessage
This is line 1.
This is line 2.
Line 3.
EndOfMessage

The string after << indicates where to stop.

To send these lines to a file, use:

cat > $FILE <<- EOM
Line 1.
Line 2.
EOM

You could also store these lines to a variable:

read -r -d '' VAR << EOM
This is line 1.
This is line 2.
Line 3.
EOM

This stores the lines to the variable named VAR.

When printing, remember the quotes around the variable otherwise you won't see the newline characters.

echo "$VAR"

Even better, you can use indentation to make it stand out more in your code. This time just add a - after << to stop the tabs from appearing.

read -r -d '' VAR <<- EOM
    This is line 1.
    This is line 2.
    Line 3.
EOM

But then you must use tabs, not spaces, for indentation in your code.

On Windows there is an experimental build that does this, as described on the mailing list, Filter by local process name

I found an a bit different solution of my problem regarding this context. Thought worth sharing.

Most of the example create readStreams from file. But in my case readStream has to be created from JSON string coming from a message pool.

var jsonStream = through2.obj(function(chunk, encoding, callback) {
                    this.push(JSON.stringify(chunk, null, 4) + '\n');
                    callback();
                });
// message.value --> value/text to write in write.txt 
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");

//"close" event didn't work for me!
writeStream.on( 'close', function () {
    console.log( "- done!" );
    sftp.end();
    }
);

//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
    console.log( "- done!"
        sftp.end();
        }
);

// finally this worked for me!
jsonStream.on('data', function(data) {
    var toString = Object.prototype.toString.call(data);
    console.log('type of data:', toString);
    console.log( "- file transferred" );
});

jsonStream.pipe( writeStream );

This is what I did to find what UITextField is the firstResponder when the user clicks Save/Cancel in a ModalViewController:

    NSArray *subviews = [self.tableView subviews];

for (id cell in subviews ) 
{
    if ([cell isKindOfClass:[UITableViewCell class]]) 
    {
        UITableViewCell *aCell = cell;
        NSArray *cellContentViews = [[aCell contentView] subviews];
        for (id textField in cellContentViews) 
        {
            if ([textField isKindOfClass:[UITextField class]]) 
            {
                UITextField *theTextField = textField;
                if ([theTextField isFirstResponder]) {
                    [theTextField resignFirstResponder];
                }

            }
        }

    }

}

Yes, if you use numpy.nditer to build your iterator.

>>> lst = [1,2,3,4,5]
>>> itr = numpy.nditer([lst])
>>> itr.next()
1
>>> itr.next()
2
>>> itr.finished
False
>>> itr.reset()
>>> itr.next()
1

I checked your code and think you should try this:

if(!file_exists($_FILES['fileupload']['tmp_name']) || !is_uploaded_file($_FILES['fileupload']['tmp_name'])) 
    {
        echo 'No upload';
    }   
    else
        echo 'upload';

You can run the MySQL command SHOW FULL PROCESSLIST; to see what queries are being processed at any given time, but that probably won't achieve what you're hoping for.

The best method to get a history without having to modify every application using the server is probably through triggers. You could set up triggers so that every query run results in the query being inserted into some sort of history table, and then create a separate page to access this information.

Do be aware that this will probably considerably slow down everything on the server though, with adding an extra INSERT on top of every single query.

Edit: another alternative is the General Query Log, but having it written to a flat file would remove a lot of possibilities for flexibility of displaying, especially in real-time. If you just want a simple, easy-to-implement way to see what's going on though, enabling the GQL and then using running tail -f on the logfile would do the trick.

Visual Studio 2017 version 15.8 made it possible to use the PackageReferencesyntax to reference NuGet packages in Visual Studio Extensibility (VSIX) projects. This makes it much simpler to reason about NuGet packages and opens the door for having a complete meta package containing the entire VSSDK.

Installing below NuGet package will solve the EmbedInteropTypes Issue.

Install-Package Microsoft.VisualStudio.SDK.EmbedInteropTypes

There is no need to use Babel at this moment (JS has become very powerful) when you can simply use the default JavaScript module exports. Check full tutorial

Message.js

module.exports = 'Hello world';

app.js

var msg = require('./Messages.js');

console.log(msg); // Hello World

You can use the reset() function, it will return the first array member.

But fortunately, with the MySQL FOREIGN_KEY_CHECKS variable, you don't have to worry about the order of your DROP TABLE statements at all, and you can write them in any order you like -- even the exact opposite -- like this:

SET FOREIGN_KEY_CHECKS = 0;
drop table if exists customers;
drop table if exists orders;
drop table if exists order_details;
SET FOREIGN_KEY_CHECKS = 1;

For a Windows Forms app that was to be distributed to several users, many of which log in over vpn, I had tried several ways which all worked for my local machine testing but not for others. I came across a Microsoft article that I adapted and works.

using System;
using System.Security.Principal;

namespace ManageExclusion
{
    public static class UserIdentity

    {
        // concept borrowed from 
        // https://msdn.microsoft.com/en-us/library/system.security.principal.windowsidentity(v=vs.110).aspx

        public static string GetUser()
        {
            IntPtr accountToken = WindowsIdentity.GetCurrent().Token;
            WindowsIdentity windowsIdentity = new WindowsIdentity(accountToken);
            return windowsIdentity.Name;
        }
    }
}

307 came about because user agents adopted as a de facto behaviour to take POST requests that receive a 302 response and send a GET request to the Location response header.

That is the incorrect behaviour — only a 303 should cause a POST to turn into a GET. User agents should (but don't) stick with the POST method when requesting the new URL if the original POST request returned a 302.

307 was introduced to allow servers to make it clear to the user agent that a method change should not be made by the client when following the Location response header.

Here is my function to get the matches :

function getAllMatches(regex, text) {
    if (regex.constructor !== RegExp) {
        throw new Error('not RegExp');
    }

    var res = [];
    var match = null;

    if (regex.global) {
        while (match = regex.exec(text)) {
            res.push(match);
        }
    }
    else {
        if (match = regex.exec(text)) {
            res.push(match);
        }
    }

    return res;
}

// Example:

var regex = /abc|def|ghi/g;
var res = getAllMatches(regex, 'abcdefghi');

res.forEach(function (item) {
    console.log(item[0]);
});

try

if (testString.Equals(testString2)){
}

Here is a variation of @SiegeX's answer which works with traditional Bourne shell (which has no support for += assignments).

password=''
while IFS= read -r -s -n1 pass; do
  if [ -z "$pass" ]; then
     echo
     break
  else
     printf '*'
     password="$password$pass"
  fi
done

I found this other one: http://code.google.com/p/jquery-jec/

Also seems like a good option.

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

1. "[a-z]y: Copy text to the [a-z] register

2. Use :! to go to the edit command

3. Ctrl + R: Follow the register identity to paste what you copy.

It used to CentOS 7.

You can either

import * as abc from './abc';
abc.xyz();

or

import { xyz } from './abc';
xyz()

For saving the original stdout and stderr you can use:

exec [fd number]<&1 
exec [fd number]<&2

For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.

#!/bin/bash

exec 5<&1
exec 6<&2

exec 1> ~/a.txt 2>&1

echo "walla1"
echo "walla2" >&2
echo "walla3" >&5
echo "walla4" >&6

I know it is an old question, but for the record here is a kind of a solution to the problem of multiline lambda problem in which the result of one call is consumed by another call.

I hope it is not super hacky, since it is based only on standard library functions and uses no dunder methods.

Below is a simple example in which we start with x = 3 and then in the first line we add 1 and then in the second line we add 2 and get 6 as the output.

from functools import reduce

reduce(lambda data, func: func(data), [
    lambda x: x + 1,
    lambda x: x + 2
], 3)

## Output: 6

Lodash unset is suitable for removing a few unwanted keys.

const myObj = {
    keyOne: "hello",
    keyTwo: "world"
}

unset(myObj, "keyTwo");

console.log(myObj); /// myObj = { keyOne: "hello" }

I run into the same problem and none of the suggestions worked (Firefox on Windows XP).

So I found a possible workaround using image data to display a little checkmark:

span:before {
    content:url("data:image/gif;base64,R0lGODlhCgAKAJEAAAAAAP///////wAAACH5BAEAAAIALAAAAAAKAAoAAAISlG8AeMq5nnsiSlsjzmpzmj0FADs=");
}

Of course you can create your own checkmark image and use a converter to add it as data:image/gif. Hope this helps.

Active Mode—The client issues a PORT command to the server signaling that it will “actively” provide an IP and port number to open the Data Connection back to the client.

Passive Mode—The client issues a PASV command to indicate that it will wait “passively” for the server to supply an IP and port number, after which the client will create a Data Connection to the server.

There are lots of good answers above, but this blog post includes some helpful graphics and gives a pretty solid explanation: https://titanftp.com/2018/08/23/what-is-the-difference-between-active-and-passive-ftp/

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

Note that since PHP 5.3.3, there's a flag for auto-converting numbers (the options parameter was added in PHP 5.3.0):

Search your installation of PhpMyAdmin for a file called Documentation.txt. This describes how to create a file called config.inc.php and how you can configure the username and password.

I'm a bit late but here's how I did this. The steps:

1. Create a list of all columns
2. Use itertools to take x combinations
3. Append each result R squared value to a result dataframe along with excluded column list
4. Sort the result DF in descending order of R squared to see which is the best fit.

This is the code I used on DataFrame called aft_tmt. Feel free to extrapolate to your use case..

If you don't want indention in your list and also don't care about or don't want bullets, there is the CSS-free option of using a "definition list" (HTML 4.01) or "description list" (HTML 5). Use only the non-indenting definition <dt> tags, but not the indenting description <dd> tags, neither of which produces a bullet.

<dl>
  <dt>Item 1</dt>
  <dt>Item 2</dt>
  <dt>Item 3</dt>
</dl>

The output looks like this:

Item 1
Item 2
Item 3

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

We'll never convince people to leave IE6 if we keep striving to deliver quality websites to those users.

Only IE7+ understood "position: fixed".

https://developer.mozilla.org/en-US/docs/Web/CSS/position

So you're out of luck for IE6. To get the footer semi-sticky try this:

.main {
  min-height: 100%;
  margin-bottom: -60px;
}
.footer {
  height: 60px;
}

You could also use an iFrame maybe.

This will keep the footer from 'lifting off' from the bottom of the page. If you have more than one page of content then it will push down out of site.

On a philosophical note, I'd rather point IE6 users to http://browsehappy.com/ and spend the time I save hacking for IE6 on something else.

There is no inbuilt support for the style change event in jQuery or in java script. But jQuery supports to create custom event and listen to it but every time there is a change, you should have a way to trigger it on yourself. So it will not be a complete solution.

In Java Brute force algorithm works faster than piggy backed merge sort algorithm this is because of run time optimization done by Java Dynamic compiler.

For Brute force loop rolling optimization will result in much better results.

You just need to feed the path to your file to pd.read_excel

import pandas as pd

file_path = "./my_excel.xlsx"
data_frame = pd.read_excel(file_path)

Checkout the documentation to explore parameters like skiprows to ignore rows when loading the excel

For me, this was caused by the project both directly and indirectly (through another dependency) referencing two different builds of Bouncy Castle that had different assembly names. One of the Bouncy Castle builds was the NuGet package, the other one was a debug build of the source downloaded from GitHub. Both were nominally version 1.8.1, but the project settings of the GitHub code set the assembly name to BouncyCastle whereas the NuGet package had the assembly name BouncyCastle.Crypto. Changing the project settings, thus aligning the assembly names, fixed the problem.

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.

You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.

If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-

First copy the table

CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;

Then drop columns that you want to be after the column you will insert

ALTER TABLE my_tab DROP COLUMN three;

Now add the new column (two in this example) and the ones you removed.

ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));

Lastly add back the data for the re-created columns

UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);

Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?

Try the :host > /deep/ :

Add the following to the parent.component.less file

:host {
    /deep/ app-child-component {
       //your child style
    }
}

Replace the app-child-component by your child selector

For the most recent version of Angular as of this post, it seems you must first create a MatDialogConfig object and pass it as a second parameter to dialog.open() because Typescript expects the second parameter to be of type MatDialogConfig.

const matDialogConfig = new MatDialogConfig();
matDialogConfig.width = "600px";
matDialogConfig.height = "480px";
this.dialog.open(MyDialogComponent, matDialogConfig);

It's a little tricky because of the nested IFs but here is my answer (confirmed in Google Spreadsheets):

=IF(AND(A2>=0,    A2<500),  "Less than 500", 
 IF(AND(A2>=500,  A2<1000), "Between 500 and 1000", 
 IF(AND(A2>=1000, A2<1500), "Between 1000 and 1500", 
 IF(AND(A2>=1500, A2<2000), "Between 1500 and 2000", "Undefined"))))

This really belongs with @Ramnath's answer but I can't comment as I don't have enough reputation yet. You can also use the arrange function from the dplyr package in the same way as the plyr package.

library(dplyr)
arrange(DF, ID, desc(num))

This worked for me.

private ArrayList<String> meals;
public String take(){
  return meals.remove(meals.size()-1);
}

INSERT
INTO    remotedblink.remotedatabase.remoteschema.remotetable
SELECT  *
FROM    mytable

There is no such thing as "the end of the table" in relational databases.

You don't say what system you're using, but as you already have some answers that may or may not work for Windows, I'll answer for POSIX systems.

In POSIX, keyboard input comes through something called a terminal interface, which by default buffers lines of input until Return/Enter is hit, so as to deal properly with backspace. You can change that with the tcsetattr call:

#include <termios.h>

struct termios info;
tcgetattr(0, &info);          /* get current terminal attirbutes; 0 is the file descriptor for stdin */
info.c_lflag &= ~ICANON;      /* disable canonical mode */
info.c_cc[VMIN] = 1;          /* wait until at least one keystroke available */
info.c_cc[VTIME] = 0;         /* no timeout */
tcsetattr(0, TCSANOW, &info); /* set immediately */

Now when you read from stdin (with getchar(), or any other way), it will return characters immediately, without waiting for a Return/Enter. In addition, backspace will no longer 'work' -- instead of erasing the last character, you'll read an actual backspace character in the input.

Also, you'll want to make sure to restore canonical mode before your program exits, or the non-canonical handling may cause odd effects with your shell or whoever invoked your program.

this seems to work on our site, using your ideas and a little math based upon the left edge of wrapper div. It seems redundant to go left 50% then take out 50% extra margin, but it seems to work.

div.ImgWrapper {
    width: 160px;
    height: 160px
    overflow: hidden;
    text-align: center;
}

img.CropCenter {
    left: 50%;
    margin-left: -100%;
    position: relative;
    width: auto !important;
    height: 160px !important;
}

<div class="ImgWrapper">
<a href="#"><img class="CropCenter" src="img.png"></a>
</div>

so easy, only use margin and left, right properties:

.elements {
 position: absolute;
 margin-left: auto;
 margin-right: auto;
 left: 0;
 right: 0;
}

http://www.quirksmode.org/js/cookies.html

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}

It is a conditional statement.

If browser supprts e.keyCode then take e.keyCode else e.charCode.

It is similar to

var code = event.keyCode || event.charCode

event.keyCode: Returns the Unicode value of a non-character key in a keypress event or any key in any other type of keyboard event.

event.charCode: Returns the Unicode value of a character key pressed during a keypress event.

You can also use this

document.querySelector('yourId').innerHTML = 'Content';

export in sh and related shells (such as bash), marks an environment variable to be exported to child-processes, so that the child inherits them.

export is defined in POSIX:

The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.

<script>
  function submit(){
      var userPass = document.getElementById('pass');
      var userName = document.getElementById('user');
      alert(user.value);
      alert(pass.value);
  }
</script>

<input type="text" id="user" />
<input type="text" id="pass" />
<button onclick="submit();" href="javascript:;">Submit</button>

Make it work, in values-v21 styles or theme xml needs to use this attribute:

<item name="android:windowTranslucentStatus">true</item>

That make the magic!

You can do this

cat /dev/urandom|od -N2 -An -i|awk -v f=2000 -v r=65000 '{printf "%i\n", f + r * $1 / 65536}'

If you need more details see Shell Script Random Number Generator.

Generally the first step is to not do that in the first place, but if this is already done, then you need to resort to properly quoting your column names:

SELECT `Business Name` FROM annoying_table

Usually these sorts of things are created by people who have used something like Microsoft Access and always use a GUI to do their thing.

you may be create function before so, update your function again using.

Alter FUNCTION dbo.Afisho_rankimin(@emri_rest int)
RETURNS int
AS
  BEGIN
     Declare @rankimi int
     Select @rankimi=dbo.RESTORANTET.Rankimi
     From RESTORANTET
     Where  dbo.RESTORANTET.ID_Rest=@emri_rest
     RETURN @rankimi
END
GO

SELECT dbo.Afisho_rankimin(5) AS Rankimi
GO

Use this addDate() function to add or subtract days, month or years (you will need the auxiliar function reformatDate() as well)

/**
 * $date self explanatory
 * $diff the difference to add or subtract: e.g. '2 days' or '-1 month'
 * $format the format for $date
 **/
    function addDate($date = '', $diff = '', $format = "d/m/Y") {
        if (empty($date) || empty($diff))
            return false;
        $formatedDate = reformatDate($date, $format, $to_format = 'Y-m-d H:i:s');
        $newdate = strtotime($diff, strtotime($formatedDate));
        return date($format, $newdate);
    }
    //Aux function
    function reformatDate($date, $from_format = 'd/m/Y', $to_format = 'Y-m-d') {
        $date_aux = date_create_from_format($from_format, $date);
        return date_format($date_aux,$to_format);
    }

Note: only for php >=5.3

string.find("substring") will help you. This function returns -1 when there is no substring.

I would suggest using glob.iglob() instead of the glob.glob(), as it is more efficient.

glob.iglob() Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

Which means glob.iglob() will be more efficient.

I mostly use below code to find the latest file matching to my pattern:

LatestFile = max(glob.iglob(fileNamePattern),key=os.path.getctime)

NOTE: There are variants of max function, In case of finding the latest file we will be using below variant: max(iterable, *[, key, default])

which needs iterable so your first parameter should be iterable. In case of finding max of nums we can use beow variant : max (num1, num2, num3, *args[, key])

Please find the below query also split the string with delimeter.

Select Substring(@String1,0,CharIndex(@delimeter,@String1))

I found this question and discussion very helpful and wanted to show the solution I ended up with. It is based on the answer given by @DevangRathod, but I used jQuery and made a couple tweaks to it, so wanted to show a fully commented sample to help anyone else working on something similar. I originally had been using the HTML5 data-list element, but was dissatisfied with that solution since it removes options from the drop down list that don't match text typed in the box. In my application, I wanted the full list to always be available.

Fully functional demo here: https://jsfiddle.net/abru77mm/

HTML:

<!-- 
Most style elements I left to the CSS file, but some are here.
Reason being that I am actually calculating my width dynamically
in my application so when I dynamically formulate this HTML, I
want the width and all the factors (such as padding and border
width and margin) that go into determining the proper widths to
be controlled by one piece of code, so those pieces are done in
the in-line style.  Otherwise I leave the styling to the CSS file.
-->
<div class="data-list-input" style="width:190px;">
  <select class="data-list-input" style="width:190px;">
    <option value="">&lt;Free Form Text&gt;</option>
    <option value="Male">Male</option>
    <option value="Female">Female</option>
    <!-- Note that though the select/option allows for a different
    display and internal value, there is no such distinction in the
    text box, so for all the options (except the "none" option) the
    value and content of the option should be identical. -->
  </select>
  <input class="data-list-input" style="width:160px;padding:4px 6px;border-width:1px;margin:0;" type="text" name="sex" required="required" value="">
</div>

JS:

jQuery(function() {
  //keep the focus on the input box so that the highlighting
  //I'm using doesn't give away the hidden select box to the user
  $('select.data-list-input').focus(function() {
    $(this).siblings('input.data-list-input').focus();
  });
  //when selecting from the select box, put the value in the input box
  $('select.data-list-input').change(function() {
    $(this).siblings('input.data-list-input').val($(this).val());
  });
  //When editing the input box, reset the select box setting to "free
  //form input". This is important to do so that you can reselect the
  //option you had selected if you want to.
  $('input.data-list-input').change(function() {
    $(this).siblings('select.data-list-input').val('');
  });
});

CSS:

div.data-list-input
{
    position: relative;
    height: 20px;
    display: inline-flex;
    padding: 5px 0 5px 0;
}
select.data-list-input
{
    position: absolute;
    top: 5px;
    left: 0px;
    height: 20px;
}
input.data-list-input
{
    position: absolute;
    top: 0px;
    left: 0px;
    height: 20px;
}

Any comments for improvement on my implementation welcome. Hope someone finds this helpful.

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

This isolation level allows dirty reads. One transaction may see uncommitted changes made by some other transaction.

To maintain the highest level of isolation, a DBMS usually acquires locks on data, which may result in a loss of concurrency and a high locking overhead. This isolation level relaxes this property.

You may want to check out the Wikipedia article on READ UNCOMMITTED for a few examples and further reading.

You may also be interested in checking out Jeff Atwood's blog article on how he and his team tackled a deadlock issue in the early days of Stack Overflow. According to Jeff:

But is nolock dangerous? Could you end up reading invalid data with read uncommitted on? Yes, in theory. You'll find no shortage of database architecture astronauts who start dropping ACID science on you and all but pull the building fire alarm when you tell them you want to try nolock. It's true: the theory is scary. But here's what I think: "In theory there is no difference between theory and practice. In practice there is."

I would never recommend using nolock as a general "good for what ails you" snake oil fix for any database deadlocking problems you may have. You should try to diagnose the source of the problem first.

But in practice adding nolock to queries that you absolutely know are simple, straightforward read-only affairs never seems to lead to problems... As long as you know what you're doing.

One alternative to the READ UNCOMMITTED level that you may want to consider is the READ COMMITTED SNAPSHOT. Quoting Jeff again:

Snapshots rely on an entirely new data change tracking method ... more than just a slight logical change, it requires the server to handle the data physically differently. Once this new data change tracking method is enabled, it creates a copy, or snapshot of every data change. By reading these snapshots rather than live data at times of contention, Shared Locks are no longer needed on reads, and overall database performance may increase.

var string = "Hello";
var str = string.substring(0, string.length-1);
alert(str);

http://jsfiddle.net/d72ML/

https://stackoverflow.com/a/9824943/14731 contains a better answer (one that is more readable and works with set -o nounset enabled). It works roughly like this:

if [ -n "${VAR-}" ]; then
    echo "VAR is set and is not empty"
elif [ "${VAR+DEFINED_BUT_EMPTY}" = "DEFINED_BUT_EMPTY" ]; then
    echo "VAR is set, but empty"
else
    echo "VAR is not set"
fi

I found that JavaScript can return a correct date when you use new Date(nYear, nMonth, nDate); with the over days of that month. Try to see the result of a dDate variable when you use this:

var dDate = new Date(2012, 0, 34); // the result is 3 Feb 2012

I have a SkipDate function to share:

    function DaysOfMonth(nYear, nMonth) {
        switch (nMonth) {
            case 0:     // January
                return 31; break;
            case 1:     // February
                if ((nYear % 4) == 0) {
                    return 29;
                }
                else {
                    return 28;
                };
                break;
            case 2:     // March
                return 31; break;
            case 3:     // April
                return 30; break;
            case 4:     // May
                return 31; break;
            case 5:     // June
                return 30; break;
            case 6:     // July
                return 31; break;
            case 7:     // August
                return 31; break;
            case 8:     // September
                return 30; break;

When the directory already exist:

When the directory does not exist and you want to create the parent directories:

mkdir -m 777 -p /parent/dirs/to/create/your/dir

You are trying to clone the repository over ssh: git@arobotdev..., and your SSH keys are not properly set on server. There are multiple reasons to this:

1. Your public key might not be saved in authorized_keys file of user git
2. If 1 is not true the Your private key is not saved in .ssh/ folder of your HOMEDIR.
3. Permissions are not properly set

If all 3 above are untrue then my only conclusion can be to try: git@arobotdev:AlfaRobot.git Assuming AlfaRobot.git is in HOMEDIR of git user and not inside a folder called git which resides in HOMEDIR of user git.

Just in case this helps anyone else; this error can occur in Visual Studio if you have a View as the open tab, and that tab depends on a parameter.

Close the current view and start your application and the app will start 'Normally'; if you have a view open, Visual Studio interprets this as you want to run the current view.

I had this issue. The security settings in the ControlPanel seem to be user specific. Try running it as the user you are actually running your browser as (you are not browsing as root!??) and setting the security level to Medium there. - For me, that did it.

I usually do this:

Const Q = """"

Dim a, g
a = "xyz"  
g = "abcd " & Q & a & Q

If you need to wrap strings in quotes more often in your code and find the above approach noisy or unreadable, you can also wrap it in a function:

a = "xyz"  
g = "abcd " & Q(a)

Function Q(s)
  Q = """" & s & """"
End Function

There is no such thing for HashMaps, but you can create an ImmutableMap with a builder:

final Map<String, Integer> m = ImmutableMap.<String, Integer>builder().
      put("a", 1).
      put("b", 2).
      build();

And if you need a mutable map, you can just feed that to the HashMap constructor.

final Map<String, Integer> m = Maps.newHashMap(
    ImmutableMap.<String, Integer>builder().
        put("a", 1).
        put("b", 2).
        build());

Mailjet

SMTP SETTINGS

Port: 25 or 587 (some providers block port 25)

I work by changing the port after deploying the app to the server.

• In Debug it worked for me: $mail->Port = 25;
• In Release it worked for me: $mail->Port = 587;

Just as an addition to answers that suggest to duplicate the columns and then to do cut. For duplication, paste etc. will work only for files, but not for streams. In that case, use sed instead.

cat file.txt | sed s/'.*'/'&\t&'/ | cut -f2,3

This works on both files and streams, and this is interesting if instead of just reading from a file with cat, you do something interesting before re-arranging the columns.

By comparison, the following does not work:

cat file.txt | paste - - | cut -f2,3

Here, the double stdin placeholder paste does not duplicate stdin, but reads the next line.

map doesn't relate to a Cartesian product at all, although I imagine someone well versed in functional programming could come up with some impossible to understand way of generating a one using map.

map in Python 3 is equivalent to this:

def map(func, iterable):
    for i in iterable:
        yield func(i)

and the only difference in Python 2 is that it will build up a full list of results to return all at once instead of yielding.

Although Python convention usually prefers list comprehensions (or generator expressions) to achieve the same result as a call to map, particularly if you're using a lambda expression as the first argument:

[func(i) for i in iterable]

As an example of what you asked for in the comments on the question - "turn a string into an array", by 'array' you probably want either a tuple or a list (both of them behave a little like arrays from other languages) -

 >>> a = "hello, world"
 >>> list(a)
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
>>> tuple(a)
('h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd')

A use of map here would be if you start with a list of strings instead of a single string - map can listify all of them individually:

>>> a = ["foo", "bar", "baz"]
>>> list(map(list, a))
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Note that map(list, a) is equivalent in Python 2, but in Python 3 you need the list call if you want to do anything other than feed it into a for loop (or a processing function such as sum that only needs an iterable, and not a sequence). But also note again that a list comprehension is usually preferred:

>>> [list(b) for b in a]
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

there you go.

The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.

The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.

In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.

The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.

$this->db->insert_id()  

//please try this

Just to show the difference between an exported variable being in the environment (env) and a non-exported variable not being in the environment:

If I do this:

$ MYNAME=Fred
$ export OURNAME=Jim

then only $OURNAME appears in the env. The variable $MYNAME is not in the env.

$ env | grep NAME
OURNAME=Jim

but the variable $MYNAME does exist in the shell

$ echo $MYNAME
Fred

For multiple text boxes - add them into a list and show all errors into 1 messagebox.

// Append errors into 1 Message Box      

 List<string> errors = new List<string>();   

 if (string.IsNullOrEmpty(textBox1.Text))
    {
        errors.Add("User");
    }

    if (string.IsNullOrEmpty(textBox2.Text))
    {
        errors.Add("Document Ref Code");
    }

    if (errors.Count > 0)
    {
        errors.Insert(0, "The following fields are empty:");
        string message = string.Join(Environment.NewLine, errors);
        MessageBox.Show(message, "errors", MessageBoxButtons.OK, MessageBoxIcon.Warning);
        return;
    } 

You'll need to create an Action on your Controller that returns the rendered result of the "UserDetails" partial view or control. Then just use an Http Get or Post from jQuery to call the Action to get the rendered html to be displayed.

Here's a method using display:flex:

.container {_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  display: flex;_x000D_
  position: fixed;_x000D_
  align-items: center;_x000D_
  justify-content: center;_x000D_
}

<div class="container">_x000D_
  <div>centered text!</div>_x000D_
</div>
