Basically, I've included there a bash script named "runEvery.sh" which you can run with cron every 1 minute and pass as arguments the real command you wish to run and the frequency in seconds in which you want to run it.

something like this

* * * * * ~/bin/runEvery.sh 5 myScript.sh

I am using this method to implement the same thing, but for some reason I am getting an exception on the ReadObject method: "Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''." Any ideas why? – Dan Appleyard Apr 6 '10 at 17:57

I had the same problem (MVC 3 build 3.0.11209.0), and the post below solved it for me. Basically the json serializer is trying to read a stream which is not at the beginning, so repositioning the stream to 0 'fixed' it...

basename and dirname solutions are more convenient. Those are alternative commands:

FILE_PATH="/opt/datastores/sda2/test.old.img"
echo "$FILE_PATH" | sed "s/.*\///"

This returns test.old.img like basename.

This is salt filename without extension:

echo "$FILE_PATH" | sed -r "s/.+\/(.+)\..+/\1/"

It returns test.old.

And following statement gives the full path like dirname command.

echo "$FILE_PATH" | sed -r "s/(.+)\/.+/\1/"

It returns /opt/datastores/sda2

Good or bad news for you, that hash IS the revision number. I also had trouble with this when I made the switch from SVN to git.

You can use "tagging" in git to tag a certain revision as the "release" for a specific version, making it easy to refer to that revision. Check out this blog post.

The key thing to understand is that git cannot have revision numbers - think about the decentralized nature. If users A and B are both committing to their local repositories, how can git reasonably assign a sequential revision number? A has no knowledge of B before they push/pull each other's changes.

Another thing to look at is simplified branching for bugfix branches:

Start with a release: 3.0.8. Then, after that release, do this:

git branch bugfixes308

This will create a branch for bugfixes. Checkout the branch:

git checkout bugfixes308

Now make any bugfix changes you want.

git commit -a

Commit them, and switch back to the master branch:

git checkout master

Then pull in those changes from the other branch:

git merge bugfixes308

That way, you have a separate release-specific bugfix branch, but you're still pulling the bugfix changes into your main dev trunk.

In MSVC, you can use the CLR override keyword even if you're not compiling for CLR.

In g++, there's no direct way of enforcing that in all cases; other people have given good answers on how to catch signature differences using -Woverloaded-virtual. In a future version, someone might add syntax like __attribute__ ((override)) or the equivalent using the C++0x syntax.

After trying various options, following configuration worked for both http and https:

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                builder.build(), SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

Registry<ConnectionSocketFactory> registry = RegistryBuilder. 
                 <ConnectionSocketFactory> create()
                .register("http", new PlainConnectionSocketFactory())
                .register("https", sslsf)
                .build();

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(2000);

CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .setConnectionManager(cm)
                .build();

Don't know what you are doing (helpful to show what you tried that didn't work), but your claim that cex.axis only affects the x-axis is not true:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data = foo, cex.axis = 3)

at least for me with:

Also, cex.axis affects the labelling of tick marks. cex.lab is used to control what R call the axis labels.

plot(Y ~ X, data = foo, cex.lab = 3)

but even that works for both the x- and y-axis.

Following up Jens' comment about using barplot(). Check out the cex.names argument to barplot(), which allows you to control the bar labels:

dat <- rpois(10, 3) names(dat) <- LETTERS[1:10] barplot(dat, cex.names = 3, cex.axis = 2)

As you mention that cex.axis was only affecting the x-axis I presume you had horiz = TRUE in your barplot() call as well? As the bar labels are not drawn with an axis() call, applying Joris' (otherwise very useful) answer with individual axis() calls won't help in this situation with you using barplot()

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

I prefer a while loop. It's more clear to me than decrementing i in the condition of a for loop

int i = arrayLength;
while(i)
{
    i--;
    //do something with array[i]
}

See File#listFiles(FilenameFilter).

File dir = new File(".");
File [] files = dir.listFiles(new FilenameFilter() {
    @Override
    public boolean accept(File dir, String name) {
        return name.endsWith(".xml");
    }
});

for (File xmlfile : files) {
    System.out.println(xmlfile);
}

If you want to use .get you can do it like this

http.get(url, function(res){
    res.setEncoding('utf8');
    res.on('data', function(chunk){
        console.log(chunk);
    });

});

I realize this is an old post but as I just ran into the same issue and had trouble finding the answer I thought I'd add a bit.

So @hammar's answer is correct. Using push.default simple is, in a way, like configuring tracking on your branches so you don't need to specify remotes and branches when pushing and pulling. The matching option will push all branches to their corresponding counterparts on the default remote (which is the first one that was set up unless you've configured your repo otherwise).

One thing I hope others find useful in the future is that I was running Git 1.8 on OS X Mountain Lion and never saw this error. Upgrading to Mavericks is what suddenly made it show up (running git --version will show git version 1.8.3.4 (Apple Git-47) which I'd never seen until the update to the OS.

With Python 3.6 you can use:

from datetime import datetime
datetime.utcnow().isoformat(sep=' ', timespec='milliseconds')

Output:

'2019-05-10 09:08:53.155'

More info here: https://docs.python.org/3/library/datetime.html#datetime.datetime.isoformat

I think you want (this won't fit in a int though, you'll need to store it as a long):

long result = dateDate.Year * 10000000000 + dateDate.Month * 100000000 + dateDate.Day * 1000000 + dateDate.Hour * 10000 + dateDate.Minute * 100 + dateDate.Second;

Alternatively, storing the ticks is a better idea.

Yes, if you really want / need to do it you can use PowerMock. This should be considered a last resort. With PowerMock you can cause it to return a mock from the call to the constructor. Then do the verify on the mock. That said, csturtz's is the "right" answer.

Here is the link to Mock construction of new objects

2.51 * 100 = 250.999999999997

The int() function simply truncates the number at the decimal point, giving 250. Use

int(round(2.51*100)) 

to get 251 as an integer. In general, floating point numbers cannot be represented exactly. One should therefore be careful of round-off errors. As mentioned, this is not a Python-specific problem. It's a recurring problem in all computer languages.

Dictionaries in Python are data structures that store key-value pairs. You can use them like associative arrays. Curly braces are used when declaring dictionaries:

d = {'One': 1, 'Two' : 2, 'Three' : 3 }
print d['Two'] # prints "2"

Curly braces are not used to denote control levels in Python. Instead, Python uses indentation for this purpose.

I think you really need some good resources for learning Python in general. See https://stackoverflow.com/q/175001/10077

This is an answer I've already given some time ago:

It depends entirely on the domain-specific application needs. A lot of times direct text file/binary files access can be extremely fast, efficient, as well as providing you all the file access capabilities of your OS's file system.

Furthermore, your programming language most likely already has a built-in module (or is easy to make one) for specific parsing.

If what you need is many appends (INSERTS?) and sequential/few access little/no concurrency, files are the way to go.

On the other hand, when your requirements for concurrency, non-sequential reading/writing, atomicity, atomic permissions, your data is relational by the nature etc., you will be better off with a relational or OO database.

There is a lot that can be accomplished with SQLite3, which is extremely light (under 300kb), ACID compliant, written in C/C++, and highly ubiquitous (if it isn't already included in your programming language -for example Python-, there is surely one available). It can be useful even on db files as big as 140 terabytes, or 128 tebibytes (Link to Database Size), possible more.

If your requirements where bigger, there wouldn't even be a discussion, go for a full-blown RDBMS.

As you say in a comment that "the system" is merely a bunch of scripts, then you should take a look at pgbash.

When creating a maven project in eclipse, the build path is set to JDK 1.5 regardless of settings, which is probably a bug in new project or m2e.

I ran into this problem today and wanted to share my solution. In my case, the solution was to delete the Child items before getting the Parent from the database.

Previously I was doing it like in the code below. I will then get the same error listed in this question.

var Parent = GetParent(parentId);
var children = Parent.Children;
foreach (var c in children )
{
     Context.Children.Remove(c);
}
Context.SaveChanges();

What worked for me, is to get the children items first, using the parentId (foreign key) and then delete those items. Then I can get the Parent from the database and at that point, it should not have any children items anymore and I can add new children items.

var children = GetChildren(parentId);
foreach (var c in children )
{
     Context.Children.Remove(c);
}
Context.SaveChanges();

var Parent = GetParent(parentId);
Parent.Children = //assign new entities/items here

Search for services.msc and look up through your services that are running if there is a mysql service running already other than the one you want to run (it could be xampp or wamp) or another service (for example Skype) using the same port as mysql and stop the service so you can run your mysql service.

Just in case anyone else encounters the same problems.

Note, that relations are required to be camelcase. So in my case available_videos() should have been availableVideos().

You can easily find out investigating the Laravel source:

// Illuminate\Database\Eloquent\Model.php
...
/**
 * Get an attribute from the model.
 *
 * @param  string  $key
 * @return mixed
 */
public function getAttribute($key)
{
    $inAttributes = array_key_exists($key, $this->attributes);

    // If the key references an attribute, we can just go ahead and return the
    // plain attribute value from the model. This allows every attribute to
    // be dynamically accessed through the _get method without accessors.
    if ($inAttributes || $this->hasGetMutator($key))
    {
        return $this->getAttributeValue($key);
    }

    // If the key already exists in the relationships array, it just means the
    // relationship has already been loaded, so we'll just return it out of
    // here because there is no need to query within the relations twice.
    if (array_key_exists($key, $this->relations))
    {
        return $this->relations[$key];
    }

    // If the "attribute" exists as a method on the model, we will just assume
    // it is a relationship and will load and return results from the query
    // and hydrate the relationship's value on the "relationships" array.
    $camelKey = camel_case($key);

    if (method_exists($this, $camelKey))
    {
        return $this->getRelationshipFromMethod($key, $camelKey);
    }
}

This also explains why my code worked, whenever I loaded the data using the load() method before.

Anyway, my example works perfectly okay now, and $model->availableVideos always returns a Collection.

From my experience with GCC I know that static and static inline differs in a way how compiler issue warnings about unused functions. More precisely when you declare static function and it isn't used in current translation unit then compiler produce warning about unused function, but you can inhibit that warning with changing it to static inline.

Thus I tend to think that static should be used in translation units and benefit from extra check compiler does to find unused functions. And static inline should be used in header files to provide functions that can be in-lined (due to absence of external linkage) without issuing warnings.

Unfortunately I cannot find any evidence for that logic. Even from GCC documentation I wasn't able to conclude that inline inhibits unused function warnings. I'd appreciate if someone will share links to description of that.

Some JavaScript engines can parse that format directly, which makes the task pretty easy:

function convertDate(inputFormat) {_x000D_
  function pad(s) { return (s < 10) ? '0' + s : s; }_x000D_
  var d = new Date(inputFormat)_x000D_
  return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')_x000D_
}_x000D_
_x000D_
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"

In DOS/Windows Batch most commands return an exitCode, called "errorlevel", that is a value that customarily is equal to zero if the command ends correctly, or a number greater than zero if ends because an error, with greater numbers for greater errors (hence the name).

There are a couple methods to check that value, but the original one is:

IF ERRORLEVEL value command

Previous IF test if the errorlevel returned by the previous command was GREATER THAN OR EQUAL the given value and, if this is true, execute the command. For example:

verify bad-param
if errorlevel 1 echo Errorlevel is greater than or equal 1
echo The value of errorlevel is: %ERRORLEVEL%

Findstr command return 0 if the string was found and 1 if not:

CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat
IF ERRORLEVEL 1 XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y

Previous code will copy the file if the string was NOT found in the file.

CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat
IF NOT ERRORLEVEL 1 XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y

Previous code copy the file if the string was found. Try this:

findstr "string" file
if errorlevel 1 (
    echo String NOT found...
) else (
    echo String found
)

I had the exact same issue. If you are using a relative path os.path.dirname(path) will only return the relative path. os.path.realpath does the trick:

>>> import os
>>> f = open('file.txt')
>>> os.path.realpath(f.name)

Given its complexibility, I think you should go the urlparse way.

For completeness, here's the pseudo-BNF of the above regex (as a documentation):

; The generic form of a URL is:

                 waisurl | mailtourl | fileurl |
                 prosperourl | otherurl

; new schemes follow the general syntax
otherurl       = genericurl

; the scheme is in lower case; interpreters should use case-ignore
scheme         = 1*[ lowalpha | digit | "+" | "-" | "." ]

Just use a normal Javascript expression, no {} or anything necessary:

@click="addToCount(item.contactID)"

if you also need the event object:

@click="addToCount(item.contactID, $event)"

For testing purposes (to avoid cached redirects), people can open NEW PRIVATE WINDOW: click CTRL+SHIFT+N [if you use Mozilla, use P]

As the top answer here is suggesting something wrong (or at least too complicated), I feel this should be updated, although the question is quite old:

When using String resources in Android, you just have to call getString(...) from Java code or use android:text="@string/..." in your layout XML.

Even if you want to use HTML markup in your Strings, you don't have to change a lot:

The only characters that you need to escape in your String resources are:

• double quotation mark: " becomes \"
• single quotation mark: ' becomes \'
• ampersand: & becomes & or &

That means you can add your HTML markup without escaping the tags:

<string name="my_string"><b>Hello World!</b> This is an example.</string>

However, to be sure, you should only use <b>, <i> and <u> as they are listed in the documentation.

If you want to use your HTML strings from XML, just keep on using android:text="@string/...", it will work fine.

The only difference is that, if you want to use your HTML strings from Java code, you have to use getText(...) instead of getString(...) now, as the former keeps the style and the latter will just strip it off.

It's as easy as that. No CDATA, no Html.fromHtml(...).

You will only need Html.fromHtml(...) if you did encode your special characters in HTML markup. Use it with getString(...) then. This can be necessary if you want to pass the String to String.format(...).

This is all described in the docs as well.

Edit:

There is no difference between getText(...) with unescaped HTML (as I've proposed) or CDATA sections and Html.fromHtml(...).

See the following graphic for a comparison:

Do this: Step 1: Your String

String str = ";;;;;;\n" +
            "Name, number, address;;;;;;\n" + 
             "01.01.12-16.02.12;;;;;;\n" + 
             ";;;;;;\n" + 
             ";;;;;;";

Step 2: Just replace all "\n" with "%n" the result looks like this

String str = ";;;;;;%n" +
             "Name, number, address;;;;;;%n" + 
             "01.01.12-16.02.12;;;;;;%n" + 
            ";;;;;;%n" + 
            ";;;;;;";

Notice I've just put "%n" in place of "\n"

Step 3: Now simply call format()

str=String.format(str);

That's all you have to do.

If the DataGridView is bound to any datasource, you'll have to set the DataGridView's DataSource property to Nothing.

If the DataGridView is not bound to any data source, this code will do the trick:

DataGridView.Rows.Clear()

There's an easier solution for this, but it requires that you know exactly how much inheritance your current class has gone through. Fortunately, get_parent_class()'s arguments allow your class array member to be the class name as a string as well as an instance itself.

Bear in mind that this also inherently relies on calling a class' __construct() method statically, though within the instanced scope of an inheriting object the difference in this particular case is negligible (ah, PHP).

Consider the following:

class Foo {
    var $f = 'bad (Foo)';

    function __construct() {
        $this->f = 'Good!';
    }
}

class Bar extends Foo {
    var $f = 'bad (Bar)';
}

class FooBar extends Bar {
    var $f = 'bad (FooBar)';

    function __construct() {
        # FooBar constructor logic here
        call_user_func(array(get_parent_class(get_parent_class($this)), '__construct'));
    }
}

$foo = new FooBar();
echo $foo->f; #=> 'Good!'

Again, this isn't a viable solution for a situation where you have no idea how much inheritance has taken place, due to the limitations of debug_backtrace(), but in controlled circumstances, it works as intended.

When building TensorFlow from source, you'll run the configure script. One of the questions that the configure script asks is as follows:

Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]

The configure script will attach the flag(s) you specify to the bazel command that builds the TensorFlow pip package. Broadly speaking, you can respond to this prompt in one of two ways:

• If you are building TensorFlow on the same type of CPU type as the one on which you'll run TensorFlow, then you should accept the default (-march=native). This option will optimize the generated code for your machine's CPU type.
• If you are building TensorFlow on one CPU type but will run TensorFlow on a different CPU type, then consider supplying a more specific optimization flag as described in the gcc documentation.

After configuring TensorFlow as described in the preceding bulleted list, you should be able to build TensorFlow fully optimized for the target CPU just by adding the --config=opt flag to any bazel command you are running.

Set the dimensions to the View and make sure your Image is styled with height and width set to 'undefined' like the example below :

    <View style={{width: 10, height:10 }} >
      <Image style= {{flex:1 , width: undefined, height: undefined}}    
       source={require('../yourfolder/yourimage')}
        />
    </View>

This will make sure your image scales and fits perfectly into your view.

You can do this with animation-keyframe rather than transition. Change your hover declaration and add the animation keyframe, you might also need to add browser prefixes for -moz- and -webkit-. See https://developer.mozilla.org/en/docs/Web/CSS/@keyframes for more detailed info.

You can see in this List of useful HTTP headers.

X-XSS-Protection: This header enables the Cross-site scripting (XSS) filter built into most recent web browsers. It's usually enabled by default anyway, so the role of this header is to re-enable the filter for this particular website if it was disabled by the user. This header is supported in IE 8+, and in Chrome (not sure which versions). The anti-XSS filter was added in Chrome 4. Its unknown if that version honored this header.

Here's what I do (please note that the JSON going to my server needs to be a dictionary with one value (another dictionary) for key = question..i.e. {:question => { dictionary } } ):

NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
  [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

NSString *jsonRequest = [jsonDict JSONRepresentation];

NSLog(@"jsonRequest is %@", jsonRequest);

NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
             cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


NSData *requestData = [jsonRequest dataUsingEncoding:NSUTF8StringEncoding];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];

NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
 receivedData = [[NSMutableData data] retain];
}

The receivedData is then handled by:

NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [jsonString JSONValue];
NSDictionary *question = [jsonDict objectForKey:@"question"];

This isn't 100% clear and will take some re-reading, but everything should be here to get you started. And from what I can tell, this is asynchronous. My UI is not locked up while these calls are made. Hope that helps.

The one I found very useful is the following:

  </xsl:when>

Expanding on @Mohamed's answer. You could use a little encapsulation

Like this:

jQuery.fn.mouseIsOver = function () {
    if($(this[0]).is(":hover"))
    {
        return true;
    }
    return false;
}; 

Use it like:

$("#elem").mouseIsOver();//returns true or false

Forked the fiddle: http://jsfiddle.net/cgWdF/1/

Another way is:

$NAME = "John";
$EMAIL = "[email protected]";
$USERNAME = "John123";
$PASSWORD = "1234";
$array = Array ("$NAME","$EMAIL","$USERNAME","$PASSWORD");
function getAndReturn (Array $array){
    return $array;
}
print_r(getAndReturn($array));

This is a slightly more general answer with more explanation for future viewers.

Add a text changed listener

If you want to find the text length or do something else after the text has been changed, you can add a text changed listener to your edit text.

EditText editText = (EditText) findViewById(R.id.testEditText);
editText.addTextChangedListener(new TextWatcher() {

    @Override
    public void beforeTextChanged(CharSequence charSequence, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int start, int before, int count)  {

    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
});

The listener needs a TextWatcher, which requires three methods to be overridden: beforeTextChanged, onTextChanged, and afterTextChanged.

Counting the characters

You can get the character count in onTextChanged or beforeTextChanged with

charSequence.length()

or in afterTextChanged with

editable.length()

Meaning of the methods

The parameters are a little confusing so here is a little extra explanation.

beforeTextChanged

beforeTextChanged(CharSequence charSequence, int start, int count, int after)

• charSequence: This is the text content before the pending change is made. You should not try to change it.
• start: This is the index of where the new text will be inserted. If a range is selected, then it is the beginning index of the range.
• count: This is the length of selected text that is going to be replaced. If nothing is selected then count will be 0.
• after: this is the length of the text to be inserted.

onTextChanged

onTextChanged(CharSequence charSequence, int start, int before, int count)

• charSequence: This is the text content after the change was made. You should not try to modify this value here. Modify the editable in afterTextChanged if you need to.
• start: This is the index of the start of where the new text was inserted.
• before: This is the old value. It is the length of previously selected text that was replaced. This is the same value as count in beforeTextChanged.
• count: This is the length of text that was inserted. This is the same value as after in beforeTextChanged.

afterTextChanged

afterTextChanged(Editable editable)

Like onTextChanged, this is called after the change has already been made. However, now the text may be modified.

• editable: This is the editable text of the EditText. If you change it, though, you have to be careful not to get into an infinite loop. See the documentation for more details.

Supplemental image from this answer

I was following the replies, When editing /etc/group I also deleted this line:

ssl-cert:x:112:postgres

then, when trying to install postgresql, I got this error

Preconfiguring packages ...
dpkg: unrecoverable fatal error, aborting:
 syntax error: unknown group 'ssl-cert' in statoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)

Putting the "ssl-cert:x:112:postgres" line back in /etc/group seems to fix it (so I was able to install postgresql)

Adam, following your comment above ("I wanted the empty plot to serve as filler in a multiplot (mfrow) plot."), what you actually want is the mfg option

    par(mfg=c(row,column))

- which controls where you want to put the next plot. For instance, to put a plot in the middle of a 3x3 multiplot, do

    par(mfrow=c(3,3))
    par(mfg=c(2,2))
    plot(rnorm(10))

I was having the similar issue when using VirtualBox on Ubuntu 12.04LTS. Now if anyone is using or has ever used Ubuntu, you might be aware that how things are hard sometimes when using shortcut keys in Ubuntu. For me, when i was trying to revert back the Host key, it was just not happening and the shortcut keys won't just work. I even tried the command line option to revert back the scale mode and it won't work either. Finally i found the following when all the other options fails:

Fix the Scale Mode Issue in Oracle VirtualBox in Ubuntu using the following steps:

1. Close all virtual machines and VirtualBox windows.

2. Find your machine config files (i.e. /home/<username>/VirtualBox VMs/ANKSVM) where ANKSVM is your VM Name and edit and change the following in ANKSVM.vbox and ANKSVM.vbox-prev files:

3. Edit the line: <ExtraDataItem name="GUI/Scale" value="on"/> to <ExtraDataItem name="GUI/Scale" value="off"/>

4. Restart VirtualBox

You are done.

This works every time specially when all other options fails like how it happened for me.

"Android-java" is here by no means different than "normal java", so yes Collections.sort() would be a good approach.

I don't not agree with vipin cp.

The true is that first bit is used for represent the sign. But 1 is for negative and 0 is for positive values. More over negative values are coded in different way (two's complement). Example with TINYINT:

The sign bit
|
1000 0000b = -128d  
...  
1111 1101b = -3d  
1111 1110b = -2d  
1111 1111b = -1d  

0000 0000b = 0d  
0000 0001b = 1d  
0000 0010b = 2d  
...  
0111 1111b = 127d  

This worked form me.. PHP Code on page.php

 $query_de="sql statements here";
 $sql_de = sqlsrv_query($conn,$query_de);
      if ($sql_de)
      {
        echo "SQLSuccess";
       }
         exit();

and then AJAX Code has bellow

jQuery.ajax({
                    url  : "page.php",
                    type : "POST",
                    data : {
                            buttonsave   : 1,
                            var1         : val1,
                            var2         : val2,
                              },
                  success:function(data)
                           {
                     if(jQuery.trim(data) === "SQLSuccess")
                                   {
                           alert("Se agrego correctamente");
                          // alert(data);
                                      } else { alert(data);}
                              },
                   error: function(error)
                           {
                    alert("Error AJAX not working: "+ error );
                              } 
               }); 

NOTE: the word 'SQLSuccess' must be received from PHP

Yes, your example is correct. Anonymous classes can implement interfaces, and that's the only time I can think of that you'll see a class implementing an interface without the "implements" keyword. Check out another code sample right here:

interface ProgrammerInterview {
    public void read();
}

class Website {
    ProgrammerInterview p = new ProgrammerInterview() {
        public void read() {
            System.out.println("interface ProgrammerInterview class implementer");
        }
    };
}

This works fine. Was taken from this page:

http://www.programmerinterview.com/index.php/java-questions/anonymous-class-interface/

I use the bcp utility. (Bulk Copy Program) I load about 1.5 million text records each month. Each text record is 800 characters wide. On my server, it takes about 30 seconds to add the 1.5 million text records into a SQL Server table.

The instructions for bcp are at http://msdn.microsoft.com/en-us/library/ms162802.aspx

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

With this command:

 dpkg -s mysql-server | grep Status

I had the same issue, following fix solved my problem.

• Select Type as 'TIMESTAMP'

• DON'T ENTER ANYTHING IN LENGTH/VALUES FIELD. KEEP IT BLANK

• Select CURRENT_TIMESTAMP as Default value.

I am using MySQL ver 5.5.56

Use ENUM in MySQL for true / false it gives and accepts the true / false values without any extra code.

ALTER TABLE `itemcategory` ADD `aaa` ENUM('false', 'true') NOT NULL DEFAULT 'false'

although it is invalid html but you can use selector context to limit your selector in your case it would be like :

$("input[name='name']" , "#form2").val("Hello World! ");

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

long start = System.currentTimeMillis();
long end = start + 60*1000; // 60 seconds * 1000 ms/sec
while (System.currentTimeMillis() < end)
{
    // run
}

Use whichever suits your need.

If you have already run your original migration (before editing it), then you need to generate a new migration (rails generate migration add_email_to_users email:string will do the trick). It will create a migration file containing line: add_column :users, email, string Then do a rake db:migrate and it'll run the new migration, creating the new column.

If you have not yet run the original migration you can just edit it, like you're trying to do. Your migration code is almost perfect: you just need to remove the add_column line completely (that code is trying to add a column to a table, before the table has been created, and your table creation code has already been updated to include a t.string :email anyway).

You can't set a favicon from CSS - if you want to do this explicitly you have to do it in the markup as you described.

Most browsers will, however, look for a favicon.ico file on the root of the web site - so if you access http://example.com most browsers will look for http://example.com/favicon.ico automatically.

In this particular case the clearest solution is the S.Lott answer

But in some complex logical conditions I would prefer use some boolean algebra to get a clear solution.

Using De Morgan's law ¬(A^B) = ¬Av¬B

not (u0 <= u and u < u0+step)
(not u0 <= u) or (not u < u0+step)
u0 > u or u >= u0+step

then

if u0 > u or u >= u0+step:
    pass

... in this case the «clear» solution is not more clear :P

Using the new FormData object (and other ES6 stuff), you can do this to turn your entire form into JSON:

let data = {};
let formdata = new FormData(theform);
for (let tuple of formdata.entries()) data[tuple[0]] = tuple[1];

and then just xhr.send(JSON.stringify(data)); like in Jan's original answer.

You will get output from column value 9 to 26 as you have mentioned OFFSET as 8

After struggling with this for a few days, it turns out that you can't do a window.location.reload() after a window.history.go(-2), because the code stops running after the window.history.go(-2). Also the html spec basically views a history.go(-2) to the the same as hitting the back button and should retrieve the page as it was instead of as it now may be. There was some talk of setting caching headers in the webserver to turn off caching but I did not want to do this.

The solution for me was to use session storage to set a flag in the browser with sessionStorage.setItem('refresh', 'true'); Then in the "theme" or the next page that needs to be refreshed do:

if (sessionStorage.getItem("refresh") == "true") { 
    sessionStorage.removeItem("refresh"); window.location.reload()
}

So basically tell it to reload in the sessionStorage then check for that at the top of the page that needs to be reloaded.

Hope this helps someone with this bit of frustration.

My encounter with this problem was caused by my editor, Intellij. As part of its internal version controls, it had gone through and locked all hidden git files. (For various reasons, I was not using the git plugin that comes with Intellij...)

So I opened a normal dos window as Administrator, changed to the directory, and executed

attrib -R /S

That removed the lock on the files and everything worked after that and I could sync my changes using the GitHub windows client.

1. First download the dex2jar tool from Following link http://code.google.com/p/dex2jar/downloads/list

2. Extract the file it create dex2jar folder

3. Now you pick your apk file and change its extension .apk to .zip after changing extension it seems to be zip file then extract this zip file you found classes.dex file

4. Now pick classes.dex file and put it into dex2jar folder

5. Now open cmd window and type the path of dex2jar folder

6. Now type the command dex2jar.bat classes.dex and press Enter

7. Now Open the dex2jar folder you found classes_dex2jar.jar file

8. Next you download the java decompiler tool from the following link http://java.decompiler.free.fr/?q=jdgui

9. Last Step Open the file classes_dex2jar.jar in java decompiler tool now you can see apk code

My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

Setting setOnClickListener(null) is a good idea to remove click listener at runtime.

And also someone commented that calling View.hasOnClickListeners() after this will return true, NO my friend.

Here is the implementation of hasOnClickListeners() taken from android.view.View class

 public boolean hasOnClickListeners() {
        ListenerInfo li = mListenerInfo;
        return (li != null && li.mOnClickListener != null);
    }

Thank GOD. It checks for null.

So everything is safe. Enjoy :-)

#include <filename>

• The preprocessor searches in an implementation-dependent manner. It tells the compiler to search directory where system header files are held.
• This method usually use to find standard header files.

#include "filename"

• This tell compiler to search header files where program is running. If it was failed it behave like #include <filename> and search that header file at where system header files stored.
• This method usually used for identify user defined header files(header files which are created by user). There for don't use this if you want to call standard library because it takes more compiling time than #include <filename>.

If I correctly understood your use case, I suggest to try using svn add to put the new folder under version, see here. The following will add the new folder with files recursively under version control (if you are inside valid working copy):

svn add new_folder
svn commit -m "Add New folder to the project"

If you are not in a working copy, create it with svn checkout, copy new_folder there and do the above steps.

OR

Try svn import, see here; the following will create a new folder and upload files to the repository:

svn import -m "Import new folder to the project" new_folder \
        http://SVN_REPO/repos/trunk/new_folder

Also note that:

After importing data, note that the original tree is not under version control. To start working, you still need to svn checkout a fresh working copy of the tree

I found the root of this message in my code, which searched and hid or showed nodes (offline). This was my code:

search.addEventListener('keyup', function() {
    for (const node of nodes)
        if (node.innerText.toLowerCase().includes(this.value.toLowerCase()))
            node.classList.remove('hidden');
        else
            node.classList.add('hidden');
});

The performance tab (profiler) shows the event taking about 60 ms:

Now:

search.addEventListener('keyup', function() {
    const nodesToHide = [];
    const nodesToShow = [];
    for (const node of nodes)
        if (node.innerText.toLowerCase().includes(this.value.toLowerCase()))
            nodesToShow.push(node);
        else
            nodesToHide.push(node);

    nodesToHide.forEach(node => node.classList.add('hidden'));
    nodesToShow.forEach(node => node.classList.remove('hidden'));
});

The performance tab (profiler) now shows the event taking about 1 ms:

And I feel that the search works faster now (229 nodes).

If the external site doesn't support JSONP or CORS, your only option is to use a proxy.

Build a script on your server that requests that content, then use jQuery ajax to hit the script on your server.

Simple way to get age as text is as below:

Select cast((DATEDIFF(m, date_of_birth, GETDATE())/12) as varchar) + ' Y & ' + 
       cast((DATEDIFF(m, date_of_birth, GETDATE())%12) as varchar) + ' M' as Age

Results Format will be:

**63 Y & 2 M**

ip route | grep rmnet_data0 | cut -d" " -f1 | cut -d"/" -f1

Change rmnet_data0 to the desired nic, in my case, rmnet_data0 represents the data nic.

To get a list of the available nic's you can use ip route

Importing a whole library seems inefficient when all you need is essentially two lines of code...

$ldap = ldap_connect("ldap.example.com");
if ($bind = ldap_bind($ldap, $_POST['username'], $_POST['password'])) {
  // log them in!
} else {
  // error message
}

What you are doing is correct, the problem is somewhere else, e.g. the cookie is being set again somehow on refresh.

You definitely can achieve that with nbconvert using the following command:

jupyter nbconvert --to python while.ipynb 

However, having used it personally I would advise against it for several reasons:

1. It's one thing to be able to convert to simple Python code and another to have all the right abstractions, classes access and methods set up. If the whole point of you converting your notebook code to Python is getting to a state where your code and notebooks are maintainable for the long run, then nbconvert alone will not suffice. The only way to do that is by manually going through the codebase.
2. Notebooks inherently promote writing code which is not maintainable (https://docs.google.com/presentation/d/1n2RlMdmv1p25Xy5thJUhkKGvjtV-dkAIsUXP-AL4ffI/edit#slide=id.g3d7fe085e7_0_21). Using nbconvert on top might just prove to be a bandaid. Specific examples of where it promotes not-so-maintainable code are imports might be sprayed throughout, hard coded paths are not in one simple place to view, class abstractions might not be present, etc.
3. nbconvert still mixes execution code and library code.
4. Comments are still not present (probably were not in the notebook).
5. There is still a lack of unit tests etc.

So to summarize, there is not good way to out of the box convert python notebooks to maintainable, robust python modularized code, the only way is to manually do surgery.

In my case, I use nginx as reverse-proxy for an API Gateway URL. I got same error.

I resolved the issue when I added the following two lines to the Nginx config:

proxy_set_header Host "XXXXXX.execute-api.REGION.amazonaws.com";
proxy_ssl_server_name on;

Source is here: Setting up proxy_pass on nginx to make API calls to API Gateway

The question is answered already, but I want add more information about the causes.

Some Common Mistakes.

1.findViewById() of non existing view

Like when you use findViewById(R.id.button) when button id does not exist in layout XML.

2. Wrong cast.

If you wrong cast some class, then you get this error. Like you cast RelativeLayout to LinearLayout or EditText to TextView.

3. Activity not registered in manifest.xml

If you did not register Activity in manifest.xml then this error comes.

4. findViewById() with declaration at top level

Below code is incorrect. This will create error. Because you should do findViewById() after calling setContentView(). Because an View can be there after it is created.

public class MainActivity extends Activity {

  ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect way

  @Override
  protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mainImage = (ImageView) findViewById(R.id.imageViewMain); //correct way
    //...
  }
}

5. Starting abstract Activity class.

When you try to start an Activity which is abstract, you will will get this error. So just remove abstract keyword before activity class name.

6. Using kotlin but kotlin not configured.

If your activity is written in Kotlin and you have not setup kotlin in your app. then you will get error. You can follow simple steps as written in Android Link or Kotlin Link. You can check this answer too.

This code works well,

public class DecimalDigitsInputFilter implements InputFilter {

    private final int digitsBeforeZero;
    private final int digitsAfterZero;
    private Pattern mPattern;

    public DecimalDigitsInputFilter(int digitsBeforeZero, int digitsAfterZero) {
        this.digitsBeforeZero = digitsBeforeZero;
        this.digitsAfterZero = digitsAfterZero;
        applyPattern(digitsBeforeZero, digitsAfterZero);
    }

    private void applyPattern(int digitsBeforeZero, int digitsAfterZero) {
        mPattern = Pattern.compile("[0-9]{0," + (digitsBeforeZero - 1) + "}+((\\.[0-9]{0," + (digitsAfterZero - 1) + "})?)|(\\.)?");
    }

    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        if (dest.toString().contains(".") || source.toString().contains("."))
            applyPattern(digitsBeforeZero + 2, digitsAfterZero);
        else
            applyPattern(digitsBeforeZero, digitsAfterZero);

        Matcher matcher = mPattern.matcher(dest);
        if (!matcher.matches())
            return "";
        return null;
    }

}

applying filter:

edittext.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(5,2)});

Besides the answers already mentioned, here is an explanation of why you have some random characters at the end:
You are opening the file in r+ mode, not w mode. The key difference is that w mode clears the contents of the file as soon as you open it, whereas r+ doesn't.
This means that if your file content is "123456789" and you write "www" to it, you get "www456789". It overwrites the characters with the new input, but leaves any remaining input untouched.
You can clear a section of the file contents by using truncate(<startPosition>), but you are probably best off saving the updated file content to a string first, then doing truncate(0) and writing it all at once.
Or you can use my library :D

Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:

<social class="h2">

Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2> descendant of an element in the social class, try something like:

.social h2 {
  color: pink;
  font-size: 14px;
}

To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.

DataSet ds = new DataSet();
ds.ReadXml(fileNamePath);

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

The database registers its service name(s) with the listener when it starts up. If it is unable to do so then it tries again periodically - so if the listener starts after the database then there can be a delay before the service is recognised.

If the database isn't running, though, nothing will have registered the service, so you shouldn't expect the listener to know about it - lsnrctl status or lsnrctl services won't report a service that isn't registered yet.

You can start the database up without the listener; from the Oracle account and with your ORACLE_HOME, ORACLE_SID and PATH set you can do:

sqlplus /nolog

Then from the SQL*Plus prompt:

connect / as sysdba
startup

Or through the Grid infrastructure, from the grid account, use the srvctl start database command:

srvctl start database -d db_unique_name [-o start_options] [-n node_name]

You might want to look at whether the database is set to auto-start in your oratab file, and depending on what you're using whether it should have started automatically. If you're expecting it to be running and it isn't, or you try to start it and it won't come up, then that's a whole different scenario - you'd need to look at the error messages, alert log, possibly trace files etc. to see exactly why it won't start, and if you can't figure it out, maybe ask on Database Adminsitrators rather than on Stack Overflow.

If the database can't see +DATA then ASM may not be running; you can see how to start that here; or using srvctl start asm. As the documentation says, make sure you do that from the grid home, not the database home.

.index.tolist() is another function which you can get the index as a list:

In [1391]: datasheet.head(20).index.tolist()
Out[1391]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

If you're using Java 9, there's an easy way with less number of lines without needing to initialize or add method.

List<String> list = List.of("first", "second", "third");

With Spring 4 you only add @EnableWebMvc, for example:

@Controller
@EnableWebMvc
@RequestMapping(value = "/articles/action", headers="Accept=*/*",  produces="application/json")
public class ArticlesController {

}

Setting sourceCompatibility = JavaVersion.VERSION_1_8 enables desugaring, but it is currently unable to desugar all the Java 8 features that the Kotlin compiler uses.

Fix - Setting kotlinOptions.jvmTarget to JavaVersion.VERSION_1_8 in the app module Gradle would fix the issue.

Use Java 8 language features: https://developer.android.com/studio/write/java8-support

android {
  ...
  // Configure only for each module that uses Java 8
  // language features (either in its source code or
  // through dependencies).
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  // For Kotlin projects
  kotlinOptions {
    jvmTarget = "1.8"
  }
}

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

timeObject.setSeconds(timeObject.getSeconds() + 10)

Just use the below piece of code to get the response from restful web service url, I use social mention url.

$response = get_web_page("http://socialmention.com/search?q=iphone+apps&f=json&t=microblogs&lang=fr");
$resArr = array();
$resArr = json_decode($response);
echo "<pre>"; print_r($resArr); echo "</pre>";

function get_web_page($url) {
    $options = array(
        CURLOPT_RETURNTRANSFER => true,   // return web page
        CURLOPT_HEADER         => false,  // don't return headers
        CURLOPT_FOLLOWLOCATION => true,   // follow redirects
        CURLOPT_MAXREDIRS      => 10,     // stop after 10 redirects
        CURLOPT_ENCODING       => "",     // handle compressed
        CURLOPT_USERAGENT      => "test", // name of client
        CURLOPT_AUTOREFERER    => true,   // set referrer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,    // time-out on connect
        CURLOPT_TIMEOUT        => 120,    // time-out on response
    ); 

    $ch = curl_init($url);
    curl_setopt_array($ch, $options);

    $content  = curl_exec($ch);

    curl_close($ch);

    return $content;
}

Your 0xED 0x6E 0x2C 0x20 bytes correspond to "ín, " in ISO-8859-1, so it looks like your content is in ISO-8859-1, not UTF-8. Tell your data provider about it and ask them to fix it, because if it doesn't work for you it probably doesn't work for other people either.

Now there are a few ways to work it around, which you should only use if you cannot load the XML normally. One of them would be to use utf8_encode(). The downside is that if that XML contains both valid UTF-8 and some ISO-8859-1 then the result will contain mojibake. Or you can try to convert the string from UTF-8 to UTF-8 using iconv() or mbstring, and hope they'll fix it for you. (they won't, but you can at least ignore the invalid characters so you can load your XML)

Or you can take the long, long road and validate/fix the sequences by yourself. That will take you a while depending on how familiar you are with UTF-8. Perhaps there are libraries out there that would do that, although I don't know any.

Either way, notify your data provider that they're sending invalid data so that they can fix it.

Here's a partial fix. It will definitely not fix everything, but will fix some of it. Hopefully enough for you to get by until your provider fix their stuff.

function fix_latin1_mangled_with_utf8_maybe_hopefully_most_of_the_time($str)
{
    return preg_replace_callback('#[\\xA1-\\xFF](?![\\x80-\\xBF]{2,})#', 'utf8_encode_callback', $str);
}

function utf8_encode_callback($m)
{
    return utf8_encode($m[0]);
}

Based o my previous answer, here is a more elegant solution with a custom class:

First define this custom class:

import UIKit
import Foundation

class ActivityIndicatorView
{
    var view: UIView!

var activityIndicator: UIActivityIndicatorView!

var title: String!

init(title: String, center: CGPoint, width: CGFloat = 200.0, height: CGFloat = 50.0)
{
    self.title = title

    let x = center.x - width/2.0
    let y = center.y - height/2.0

    self.view = UIView(frame: CGRect(x: x, y: y, width: width, height: height))
    self.view.backgroundColor = UIColor(red: 255.0/255.0, green: 204.0/255.0, blue: 51.0/255.0, alpha: 0.5)
    self.view.layer.cornerRadius = 10

    self.activityIndicator = UIActivityIndicatorView(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
    self.activityIndicator.color = UIColor.blackColor()
    self.activityIndicator.hidesWhenStopped = false

    let titleLabel = UILabel(frame: CGRect(x: 60, y: 0, width: 200, height: 50))
    titleLabel.text = title
    titleLabel.textColor = UIColor.blackColor()

    self.view.addSubview(self.activityIndicator)
    self.view.addSubview(titleLabel)
}

func getViewActivityIndicator() -> UIView
{
    return self.view
}

func startAnimating()
{
    self.activityIndicator.startAnimating()
    UIApplication.sharedApplication().beginIgnoringInteractionEvents()
}

func stopAnimating()
{
    self.activityIndicator.stopAnimating()
    UIApplication.sharedApplication().endIgnoringInteractionEvents()

    self.view.removeFromSuperview()
}
//end
}

Now on your UIViewController class:

var activityIndicatorView: ActivityIndicatorView!

override func viewDidLoad()
{
    super.viewDidLoad()

    self.activityIndicatorView = ActivityIndicatorView(title: "Processing...", center: self.view.center)
    self.view.addSubview(self.activityIndicatorView.getViewActivityIndicator())

}

func doSomething()
{
    self.activityIndicatorView.startAnimating()
    UIApplication.sharedApplication().beginIgnoringInteractionEvents()

    //do something here that will taking time

    self.activityIndicatorView.stopAnimating()
}

the symbol ? after the int means that it can be nullable.

The ? symbol is usually used in situations whereby the variable can accept a null or an integer or alternatively, return an integer or null.

Hope the context of usage helps. In this way you are not restricted to solely dealing with integers.

If you're calling this outside of an Activity, you'll need to pass the context in (or get it through some other call). Then use that to get your display metrics:

DisplayMetrics metrics = context.getResources().getDisplayMetrics();
int width = metrics.widthPixels;
int height = metrics.heightPixels;

UPDATE: With API level 17+, you can use getRealSize:

Point displaySize = new Point();
activity.getWindowManager().getDefaultDisplay().getRealSize(displaySize);

If you want the available window size, you can use getDecorView to calculate the available area by subtracting the decor view size from the real display size:

Point displaySize = new Point();
activity.getWindowManager().getDefaultDisplay().getRealSize(displaySize);

Rect windowSize = new Rect();
ctivity.getWindow().getDecorView().getWindowVisibleDisplayFrame(windowSize);

int width = displaySize.x - Math.abs(windowSize.width());
int height = displaySize.y - Math.abs(windowSize.height());
return new Point(width, height);

getRealMetrics may also work (requires API level 17+), but I haven't tried it yet:

DisplayMetrics metrics = new DisplayMetrics();
activity.GetWindowManager().getDefaultDisplay().getRealMetrics(metrics);

Custom Tooltips with pure CSS - no JavaScript needed:

Example here (with code) / Full screen example

As an alternative to the default title attribute tooltips, you can make your own custom CSS tooltips using :before/:after pseudo elements and HTML5 data-* attributes.

Using the provided CSS, you can add a tooltip to an element using the data-tooltip attribute.

You can also control the position of the custom tooltip using the data-tooltip-position attribute (accepted values: top/right/bottom/left).

For instance, the following will add a tooltop positioned at the bottom of the span element.

<span data-tooltip="Custom tooltip text." data-tooltip-position="bottom">Custom bottom tooltip.</span>

How does this work?

You can display the custom tooltips with pseudo elements by retrieving the custom attribute values using the attr() function.

[data-tooltip]:before {
    content: attr(data-tooltip);
}

In terms of positioning the tooltip, just use the attribute selector and change the placement based on the attribute's value.

        public string Name
        {
            get

                return this["code"] as string;
            }
        }
}

ConfigurationElementCollection:

public class Companies
        : ConfigurationElementCollection
    {
        public Company this[int index]
        {
            get
            {
                return base.BaseGet(index) as Company ;
            }
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }

       public new Company this[string responseString]
       {

        }

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        {
            return ((Company)element).Name;
        }
    }

and ConfigurationSection:

public class RegisterCompaniesConfig
        : ConfigurationSection
    {

        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
        }

        [System.Configuration.ConfigurationProperty("Companies")]
            [ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
        public Companies Companies
        {
            get
            {
                object o = this["Companies"];
                return o as Companies ;
            }
        }

    }

and you must also register your new configuration section in web.config (app.config):

<configuration>       
    <configSections>
          <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>

then you load your config with

var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
   do something ..
}

Unicode codepoints U+D800 to U+DFFF must be avoided: they are invalid in Unicode because they are reserved for UTF-16 surrogate pairs. Some JSON encoders/decoders will replace them with U+FFFD. See for example how the Go language and its JSON library deals with them.

So avoid "\uD800" to "\uDFFF" alone (not in surrogate pairs).

I had this problem when upgrading my solution from Microsoft Visual Studio 2012 Express for Web to Microsoft Visual Studio 2013.

I had created a Unit Tests project in 2012, and after opening in 2013 the Unit Test project wouldn't show any tests in the tests explorer. Everytime I tried to run or debug tests it failed, saying the following in the output window:

    Failed to initialize client proxy: 
    could not connect to vstest.discoveryengine.x86.exe

I also noticed that on debugging the tests, it was launching an instance of Visual Studio 2012. This clued me into the fact that the Unit Tests project was still referencing 2012. Looking at the test project reference I realised it was targeting the wrong Microsoft Visual Studio Unit Test Framework DLL for this version of Visual Studio:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

I changed the version number from 11.0 to 12.0:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

I rebuilt all and this fixed the issue - all tests were found in the Test Explorer and now all tests are found and running perfectly.

All your controls are belong to us!

Fionnuala answered this correctly but skimmers like me would find it easy to miss the point.

You don't refresh the subFORM you refresh the subform CONTROL. In fact, if you check with allforms() the subForm isn't even loaded as far as access is concerned.

On the main form look at the label the subform wizard provided or select the subform by clicking once or on the border around it and look at the "caption" in the "Other" tab in properties. That's the name you use for requerying, not the name of the form that appears in the navigation panel.

In my case I had a subform called frmInvProdSub and I tried for many hours to figure out why Access didn't think it existed. I gave up, deleted the form and re-created it. The very last step is telling it what you want to call the control so I called it frmInvProdSub and finished the wizard. Then I tried and voila, it worked!

When I looked at the form name in the navigation window I realized I'd forgotten to put "Sub" in the name! That's when it clicked. The CONTROL is called frmInvProdSub, not the form and using the control name works.

Of course if both names are identical then you didn't have this problem lol.

The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).

This will do it in one line.

>>> a=[2,3,4]
>>> b=[1,2]
>>> bool(sum(map(lambda x: x in b, a)))
True

@echo off
RD %TEMP%\. /S /Q

::pause
explorer %temp%

This batch can run from anywhere. RD stands for Remove Directory but this can remove both folders and files which available to delete.

Try this

XElement root = XDocument.Load(fStream).Root;

When running python (cpython) on windows the <built-in function system> os.system will execute under the curtains _wsystem while if you're using a non-windows os, it'll use system.

On contrary, Popen should use CreateProcess on windows and _posixsubprocess.fork_exec in posix-based operating-systems.

That said, an important piece of advice comes from os.system docs, which says:

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.

You can do this easily manually for each column like this:

df['A_perc'] = df['A']/df['sum']

If you want to do this in one step for all columns, you can use the div method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):

ds.div(ds['sum'], axis=0)

And if you want this in one step added to the same dataframe:

>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')
          A         B         C         D       sum    A_perc    B_perc  \

Old question but nowadays CSS3 makes vertical alignment really simple!

Just add to the <div> this css:

display:flex;
align-items:center;
justify-content:center;

Actually you can use,

BigInteger sum= new BigInteger("12345");

for creating object for BigInteger class.But the problem here is,you cannot give a variable in the double quotes.So we have to use the valueOf() method and we have to store the answer in that sum again.So we will write,

sum= sum.add(BigInteger.valueOf(i));

In Bootstrap 4 it was renamed to .rounded-circle

Usage :

<div class="col-xs-7">
    <img src="img/gallery2.JPG" class="rounded-circle" alt="HelPic>
</div>

See migration docs from bootstrap.

In the run configuration you want to customize (just click on it) open the tab Arguments and add -Xmx2048min the VM arguments section. You might want to set the -Xms as well (small heap size).

You're missing a close paren in this line:

fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494

There are three ( and only two ).
I hope This will help you.

A more elegant solution than creating an anonymous function who's sole purpose is to wrap another, is to use es5's bind function. The bind function creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.

Instead of:

expect(function () { parser.parse(raw, config); } ).toThrow("Parsing is not possible");

Consider:

expect(parser.parse.bind(parser, raw, config)).toThrow("Parsing is not possible");

The bind syntax allows you to test functions with different this values, and in my opinion makes the test more readable. See also: https://stackoverflow.com/a/13233194/1248889

if the opening in windows

try {
        //chm file address
        String chmFile = System.getProperty("user.dir") + "/chm/sample.chm";
        Desktop.getDesktop().open(new File(chmFile));

It's a tree, so recursion is your friend: start with the parent directory and call the method to get an array of child Files. Iterate through the child array. If the current value is a directory, pass it to a recursive call of your method. If not, process the leaf file appropriately.

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));

Using the equation of the line ab, get the x-coordinate on the line at the same y-coordinate as the point to be sorted.

• If point's x > line's x, the point is to the right of the line.
• If point's x < line's x, the point is to the left of the line.
• If point's x == line's x, the point is on the line.

A bit shorter answer since PHP >= 5.3.0:

    $csvFile = file('../somefile.csv');
    $data = [];
    foreach ($csvFile as $line) {
        $data[] = str_getcsv($line);
    }

(1..10).each{

if (it < 5)

println it

else

return false

After searching a solution for the same problem like you, I've found this small topic here. In advance I got a much smoother solution for this switch, case statement

switch($someString) #switch is caseINsensitive, so you don't need to lower
{
    { 'y' -or 'yes' } { "You entered Yes." }
    default { "You entered No." }
}

void replace(char *str, char *strFnd, char *strRep)
{
    for (int i = 0; i < strlen(str); i++)
    {
        int npos = -1, j, k;
        if (str[i] == strFnd[0])
        {
            for (j = 1, k = i+1; j < strlen(strFnd); j++)
                if (str[k++] != strFnd[j])
                    break;
            npos = i;
        }
        if (npos != -1)
            for (j = 0, k = npos; j < strlen(strRep); j++)
                str[k++] = strRep[j];
    }

}

int main()
{
    char pst1[] = "There is a wrong message";
    char pfnd[] = "wrong";
    char prep[] = "right";

    cout << "\nintial:" << pst1;

    replace(pst1, pfnd, prep);

    cout << "\nfinal : " << pst1;
    return 0;
}

This is a typical startup failure due to the embedded servlet container’s port being in use.

Your embedded tomcat container failed to start because Port 8080 was already in use.

Just Identify and stop the process that's listening on port 8080 or configure (in you application.properties file )this application to listen on another port.

Please try like this,

return Article::where('id',$article)->with(['products'=>function($products, $offset, $limit) {
    return $products->offset($offset*$limit)->limit($limit);
}])

Node is asynchronous by nature, and that's what's great about it, so you really shouldn't be blocking the thread, but as this seems to be for a project controlling LED's, I'll post a workaraound anyway, even if it's not a very good one and shouldn't be used (seriously).

A while loop will block the thread, so you can create your own sleep function

function sleep(time, callback) {
    var stop = new Date().getTime();
    while(new Date().getTime() < stop + time) {
        ;
    }
    callback();
}

to be used as

sleep(1000, function() {
   // executes after one second, and blocks the thread
});

I think this is the only way to block the thread (in principle), keeping it busy in a loop, as Node doesn't have any blocking functionality built in, as it would sorta defeat the purpose of the async behaviour.

<script type="text/javascript">
    $(function(){
        $('#areaCode,#firstNum,#secNum').keyup(function(e){
            if($(this).val().length==$(this).attr('maxlength'))
                $(this).next(':input').focus()
        })
    })
    </script>

<body>

<input type="text" id="areaCode" name="areaCode" maxlength="3" value="" size="3" />- 
<input type="text" id="firstNum" name="firstNum" maxlength="3" value="" size="3" />- 
<input type="text" id="secNum" name=" secNum " maxlength="4" value="" size="4" />

</body>

you can find if one has been initialized by comparing the references with the default instance:

GRPCContainer container = myGrpcResponseBean.getContainer();
if (container.getDefaultInstanceForType() != container) {
...
}

I know this is necro-posting, but I found a real easy way to just add the margin-top and margin-bottom to the button itself without having to build anything else.

When you create the styles, whether inline or by creating an object to pass, you can do this:

var buttonStyle = {
   marginTop: "1px",
   marginBottom: "1px"
}

It seems that adding the quotes around the value makes it work. I don't know if this is because it's a later version of React versus what was posted two years ago, but I know that it works now.

You can use jQuery like:

$("input").attr("maxlength", 4)

Here is a demo: http://jsfiddle.net/TmsXG/13/

What about the ansicolors library? You can simple do:

from colors import color, red, blue

# common colors
print(red('This is red'))
print(blue('This is blue'))

# colors by name or code
print(color('Print colors by name or code', 'white', '#8a2be2'))

Yes, you can do this by creating a DoubleStream from the array, filtering out the negatives, and converting the stream back to an array. Here is an example:

double[] d = {8, 7, -6, 5, -4};
d = Arrays.stream(d).filter(x -> x > 0).toArray();
//d => [8, 7, 5]

If you want to filter a reference array that is not an Object[] you will need to use the toArray method which takes an IntFunction to get an array of the original type as the result:

String[] a = { "s", "", "1", "", "" };
a = Arrays.stream(a).filter(s -> !s.isEmpty()).toArray(String[]::new);

You can also use Aragon Package Manager if you prefer a decentralized approach:

2. Deploying APM: https://github.com/aragon/aragonOS#apm

What's perplexing to me is that the visual studio designer only allows you to use BackgroundWorkers and Timers that don't actually work with the service project.

It gives you neat drag and drop controls onto your service but... don't even try deploying it. Won't work.

Services: Only use System.Timers.Timer System.Windows.Forms.Timer won't work even though it's available in the toolbox

Services: BackgroundWorkers will not work when it's running as a service Use System.Threading.ThreadPools instead or Async calls

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

After lot of struggle finally got it working. ( Perfectly tested)

The below example will also support the fact that color of already clicked button should not be changes

JQuery Code

var flag = 0; // Flag is to check if you are hovering on already clicked item

$("a").click(function() {
    $('a').removeClass("YourColorClass");
    $(this).addClass("YourColorClass");
    flag=1;
}); 

$("a").mouseover(function() {
    if ($(this).hasClass("YourColorClass")) {
        flag=1;
    }
    else{
        $(this).addClass("YourColorClass");
    };
});

$("a").mouseout(function() {
    if (flag == 0) {
        $(this).removeClass("YourColorClass");
    }
    else{
        flag = 0;
    }
});

Just to clarify, in your 3rd example _myProperty isn't actually a property. It's a field with get and set methods (and as has already been mentioned the get and set methods should specify return types).

In C# the 3rd method should be avoided in most situations. You'd only really use it if the type you wanted to return was an array, or if the get method did a lot of work rather than just returning a value. The latter isn't really necessary but for the purpose of clarity a property's get method that does a lot of work is misleading.

As the others have said, it's for type conversion, in this case to a bool. For example:

class A {
    bool isItSafe;

public:
    operator bool() const
    {
        return isItSafe;
    }

    ...
};

Now I can use an object of this class as if it's a boolean:

A a;
...
if (a) {
    ....
}

Using this library named Toasty I think you have enough flexibility to make a customized toast by the following approach -

Toasty.custom(yourContext, "I'm a custom Toast", yourIconDrawable, tintColor, duration, withIcon, 
shouldTint).show();

You can also pass formatted text to Toasty and here is the code snippet

There's a client profile usable version, System.Net.WebUtility class, present in client profile System.dll. Here's the MSDN Link:

I came here specifically to work out how I could convert my timezoneoffset to a timezone string for converting dates to DATETIMEOFFSET in SQL Server 2008. Gross, but necessary.

So I need 1 method that will cope with negative and positive numbers, formatting them to two characters with a leading zero if needed. Anons answer got me close, but negative timezone values would come out as 0-5 rather than the required -05

So with a bit of a tweak on his answer, this works for all timezone hour conversions

DECLARE @n INT = 13 -- Works with -13, -5, 0, 5, etc
SELECT CASE 
    WHEN @n < 0 THEN '-' + REPLACE(STR(@n * -1 ,2),' ','0') 
    ELSE '+' + REPLACE(STR(@n,2),' ','0') END + ':00'

What about wrapping your call in a Promise.all() method i.e.

Promise.all([$http.get(url).then(function(result){....}, function(error){....}])

According to MDN

Promise.all waits for all fulfillments (or the first rejection)

hasOwnProperty expects the property name as a string, so it would be shape1.hasOwnProperty("name")

I tried to call

startService(oIntent);
bindService(oIntent, mConnection, Context.BIND_AUTO_CREATE);

consequently and I could create a sticky service and bind to it. Detailed tutorial for Bound Service Example.

Doctrine now has Criteria which offers a single API for filtering collections with SQL and in PHP, depending on the context.

https://www.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html#filtering-collections

Update

This will achieve the result in the accepted answer, without getting everything from the database.

use Doctrine\Common\Collections\Criteria;

/**
 * @ORM\Entity
 */
class Member {
  // ...
  public function getCommentsFiltered($ids) {
    $criteria = Criteria::create()->where(Criteria::expr()->in("id", $ids));

    return $this->getComments()->matching($criteria); 
  }
}

I had similar issue before and in my case the file was in another machine so i have mapped network drive z to the folder location where my file is then i created a context in tomcat so in my web project i could access the HTML file via context

set formatoptions-=t Keeps the visual textwidth but doesn't add new line in insert mode.

Here is a little something I cooked up today. Seems to work for me. Basically you override the Add method in your base namespace to do a check and then call the base's Add method in order to actually add it. Hope this works for you

using System;
using System.Collections.Generic;
using System.Collections;

namespace Main
{
    internal partial class Dictionary<TKey, TValue> : System.Collections.Generic.Dictionary<TKey, TValue>
    {
        internal new virtual void Add(TKey key, TValue value)
        {   
            if (!base.ContainsKey(key))
            {
                base.Add(key, value);
            }
        }
    }

    internal partial class List<T> : System.Collections.Generic.List<T>
    {
        internal new virtual void Add(T item)
        {
            if (!base.Contains(item))
            {
                base.Add(item);
            }
        }
    }

    public class Program
    {
        public static void Main()
        {
            Dictionary<int, string> dic = new Dictionary<int, string>();
            dic.Add(1,"b");
            dic.Add(1,"a");
            dic.Add(2,"c");
            dic.Add(1, "b");
            dic.Add(1, "a");
            dic.Add(2, "c");

            string val = "";
            dic.TryGetValue(1, out val);

            Console.WriteLine(val);
            Console.WriteLine(dic.Count.ToString());


            List<string> lst = new List<string>();
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");

            Console.WriteLine(lst[2]);
            Console.WriteLine(lst.Count.ToString());
        }
    }
}

I was having the same problem ConcurrentAccessException and mysolution was to:

List<SomeBean> tempList = new ArrayList<>();

for (CartItem item : prodList) {
  tempList.add(item);
}
prodList.clear();
prodList = new ArrayList<>(tempList);

So it works only one operation at the time and avoids the Exeption...

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

Goto Nuget Package manager and search for openxml. And install DocumentFormat.OpenXml

After looking for an answer for this question I found a brilliant explanation with an example that I would like to share with you.

You can watch a video that demonstrate the differences HERE

In this example we have this given code:

public interface IEmployeeRepository
{
    IEnumerable<Employee> GetAllEmployees();
    Employee Add(Employee employee);
}

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class MockEmployeeRepository : IEmployeeRepository
{
    private List<Employee> _employeeList;

    public MockEmployeeRepository()
    {
        _employeeList = new List<Employee>()
    {
        new Employee() { Id = 1, Name = "Mary" },
        new Employee() { Id = 2, Name = "John" },
        new Employee() { Id = 3, Name = "Sam" },
    };
    }

    public Employee Add(Employee employee)
    {
        employee.Id = _employeeList.Max(e => e.Id) + 1;
        _employeeList.Add(employee);
        return employee;
    }

    public IEnumerable<Employee> GetAllEmployees()
    {
        return _employeeList;
    }
}

HomeController

public class HomeController : Controller
{
    private IEmployeeRepository _employeeRepository;

    public HomeController(IEmployeeRepository employeeRepository)
    {
        _employeeRepository = employeeRepository;
    }

    [HttpGet]
    public ViewResult Create()
    {
        return View();
    }

    [HttpPost]
    public IActionResult Create(Employee employee)
    {
        if (ModelState.IsValid)
        {
            Employee newEmployee = _employeeRepository.Add(employee);
        }

        return View();
    }
}

Create View

@model Employee
@inject IEmployeeRepository empRepository

<form asp-controller="home" asp-action="create" method="post">
    <div>
        <label asp-for="Name"></label>
        <div>
            <input asp-for="Name">
        </div>
    </div>

    <div>
        <button type="submit">Create</button>
    </div>

    <div>
        Total Employees Count = @empRepository.GetAllEmployees().Count().ToString()
    </div>
</form>

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddSingleton<IEmployeeRepository, MockEmployeeRepository>();
}

Copy-paste this code and press on the create button in the view and switch between AddSingleton , AddScoped and AddTransient you will get each time a different result that will might help you understand this.

AddSingleton() - As the name implies, AddSingleton() method creates a Singleton service. A Singleton service is created when it is first requested. This same instance is then used by all the subsequent requests. So in general, a Singleton service is created only one time per application and that single instance is used throughout the application life time.

AddTransient() - This method creates a Transient service. A new instance of a Transient service is created each time it is requested.

AddScoped() - This method creates a Scoped service. A new instance of a Scoped service is created once per request within the scope. For example, in a web application it creates 1 instance per each http request but uses the same instance in the other calls within that same web request.

For me it was due to "multiple" attribute on select input control as Angular has different ValueAccessor for this type of control.

const countryControl = new FormControl();

And inside template use like this

    <select multiple name="countries" [formControl]="countryControl">
      <option *ngFor="let country of countries" [ngValue]="country">
       {{ country.name }}
      </option>
    </select>

I think realpath() may be the best way to validate if a path exist http://www.php.net/realpath

Here is an example function:

<?php
/**
 * Checks if a folder exist and return canonicalized absolute pathname (long version)
 * @param string $folder the path being checked.
 * @return mixed returns the canonicalized absolute pathname on success otherwise FALSE is returned
 */
function folder_exist($folder)
{
    // Get canonicalized absolute pathname
    $path = realpath($folder);

    // If it exist, check if it's a directory
    if($path !== false AND is_dir($path))
    {
        // Return canonicalized absolute pathname
        return $path;
    }

    // Path/folder does not exist
    return false;
}

Short version of the same function

<?php
/**
 * Checks if a folder exist and return canonicalized absolute pathname (sort version)
 * @param string $folder the path being checked.
 * @return mixed returns the canonicalized absolute pathname on success otherwise FALSE is returned
 */
function folder_exist($folder)
{
    // Get canonicalized absolute pathname
    $path = realpath($folder);

    // If it exist, check if it's a directory
    return ($path !== false AND is_dir($path)) ? $path : false;
}

Output examples

<?php
/** CASE 1 **/
$input = '/some/path/which/does/not/exist';
var_dump($input);               // string(31) "/some/path/which/does/not/exist"
$output = folder_exist($input);
var_dump($output);              // bool(false)

/** CASE 2 **/
$input = '/home';
var_dump($input);
$output = folder_exist($input);         // string(5) "/home"
var_dump($output);              // string(5) "/home"

/** CASE 3 **/
$input = '/home/..';
var_dump($input);               // string(8) "/home/.."
$output = folder_exist($input);
var_dump($output);              // string(1) "/"

Usage

<?php

$folder = '/foo/bar';

if(FALSE !== ($path = folder_exist($folder)))
{
    die('Folder ' . $path . ' already exist');
}

mkdir($folder);
// Continue do stuff

The max length of a varchar in MySQL 5.6.12 is 4294967295.

I am using Python 3.6 and using a comma between Exception and e does not work. I need to use the following syntax (just for anyone wondering)

try:
    connection = manager.connect("I2Cx")
except KeyError as e:
    print(e.message)

Since value is the last entry, you can do:

metrics.sort_by(&:last)

Inspired by Roger Pate:

def todayAt (hr, min=0, sec=0, micros=0):
   now = datetime.datetime.now()
   return now.replace(hour=hr, minute=min, second=sec, microsecond=micros)    

# Usage demo1:
print todayAt (17), todayAt (17, 15)

# Usage demo2:    
timeNow = datetime.datetime.now()
if timeNow < todayAt (13):
   print "Too Early"

If you just want to check string equality, use the == operator. Determining whether two strings are equal is simpler than finding an ordering (which is what compare() gives,) so it might be better performance-wise in your case to use the equality operator.

Longer answer: The API provides a method to check for string equality and a method to check string ordering. You want string equality, so use the equality operator (so that your expectations and those of the library implementors align.) If performance is important then you might like to test both methods and find the fastest.

This function makes use of Mozilla's __count__ property if it is available as it is faster than iterating over every property.

function countProperties(obj) {
  var count = "__count__",
  hasOwnProp = Object.prototype.hasOwnProperty;

  if (typeof obj[count] === "number" && !hasOwnProp.call(obj, count)) {
    return obj[count];
  }
  count = 0;
  for (var prop in obj) {
    if (hasOwnProp.call(obj, prop)) {
      count++;
    }
  }
  return count;
};

countProperties({
  "1": 2,
  "3": 4,
  "5": 6
}) === 3;

This may seem silly, but in the original question, Turion was editing a plain text file. Make sure you choose the correct language from the Language menu

The .htaccess is either in the root-directory of your webpage or in the directory you want to protect.

Make sure to make them visible in your filesystem, because AFAIK (I'm no unix expert either) files starting with a period are invisible by default on unix-systems.

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

These days, we use spans! So you would write:

#include <gsl/span>

...
auto start_pos = 100000;
auto length = 1000;
auto span_of_myvec = gsl::make_span(myvec);
auto my_subspan = span_of_myvec.subspan(start_pos, length);

to get a span of 1000 elements of the same type as myvec's. Or a more terse form:

auto my_subspan = gsl::make_span(myvec).subspan(1000000, 1000);

(but I don't like this as much, since the meaning of each numeric argument is not entirely clear; and it gets worse if the length and start_pos are of the same order of magnitude.)

Anyway, remember that this is not a copy, it's just a view of the data in the vector, so be careful. If you want an actual copy, you could do:

std::vector<T> new_vec(my_subspan.cbegin(), my_subspan.cend());

Notes:

• gsl stands for Guidelines Support Library. For more information about gsl, see: http://www.modernescpp.com/index.php/c-core-guideline-the-guidelines-support-library.
• There are several gsl implementations . For example: https://github.com/martinmoene/gsl-lite
• C++20 provides an implementation of span. You would use std::span and #include <span> rather than #include <gsl/span>.
• For more information about spans, see: What is a "span" and when should I use one?
• std::vector has a gazillion constructors, it's super-easy to fall into one you didn't intend to use, so be careful.

In CSS, we can cascade to the properties down the hierarchy but not in the oppostite direction. To modify the parent style on child event, probably use jQuery.

$el.closest('.parent').css('prop','value');

STATIC_DEPS=true easy_install lxml

Try this regex:

/^[\w&.-]+$/

Also you can use test.

if ( pattern.test( qry ) ) {
  // valid
}

1) add the below jquery:

$thumbnail.on('click', function(e){
 e.preventDefault();
 src = src+'&autoplay=1'; // src: the original URL for embedding 
 $videoContainer.empty().append( $iframe.clone().attr({'src': src}) ); // $iframe: the original iframe for embedding
 }
);

note: in the first src (shown) add the original youtube link.

2) edit the iframe tag as:

<iframe width="1280" height="720" src="https://www.youtube.com/embed/nfQHF87vY0s?autoplay=1" frameborder="0" allowfullscreen></iframe>

note: copy paste the youtube video id after the embed/ in the iframe src.

All these results in null:

document.getElementById('volume');
document.getElementById('bytesLoaded');
document.getElementById('startBytes');
document.getElementById('bytesTotal');

You need to do a null check in updateHTML like this:

function updateHTML(elmId, value) {
  var elem = document.getElementById(elmId);
  if(typeof elem !== 'undefined' && elem !== null) {
    elem.innerHTML = value;
  }
}

Use

"$filepath"_newstap.sh

or

${filepath}_newstap.sh

or

$filepath\_newstap.sh

_ is a valid character in identifiers. Dot is not, so the shell tried to interpolate $filepath_newstap.

You can use set -u to make the shell exit with an error when you reference an undefined variable.

You need to check out the attr method in the jQuery docs. You are misusing it. What you are doing within the if statements simply replaces all image tags src with the string specified in the 2nd parameter.

http://api.jquery.com/attr/

A better way to approach replacing a series of images source would be to loop through each and check it's source.

Example:

$('img').each(function () {
  var curSrc = $(this).attr('src');
  if ( curSrc === 'http://example.com/smith.gif' ) {
      $(this).attr('src', 'http://example.com/johnson.gif');
  }
  if ( curSrc === 'http://example.com/williams.gif' ) {
      $(this).attr('src', 'http://example.com/brown.gif');
  }
});

lblmessage.Text =Request.ServerVariables["REMOTE_HOST"].ToString();

I had the same issue as you, I figured it out. Facebook now roles some features as plugins. In the left hand side select Products and add product. Then select Facbook Login. Pretty straight forward from there, you'll see all the Oauth options show up.

In VB : This should work

ConfigurationManager.ConnectionStrings("SQLServer").ConnectionString

In C# it would be (as per comment of Ala)

ConfigurationManager.ConnectionStrings["SQLServer"].ConnectionString

You could look at using Lattice. In this example I have defined a grid over which I want to plot z~x,y. It looks something like this. Note that most of the code is just building a 3D shape that I plot using the wireframe function.

The variables "b" and "s" could be x or y.

require(lattice)

# begin generating my 3D shape
b <- seq(from=0, to=20,by=0.5)
s <- seq(from=0, to=20,by=0.5)
payoff <- expand.grid(b=b,s=s)
payoff$payoff <- payoff$b - payoff$s
payoff$payoff[payoff$payoff < -1] <- -1
# end generating my 3D shape


wireframe(payoff ~ s * b, payoff, shade = TRUE, aspect = c(1, 1),
    light.source = c(10,10,10), main = "Study 1",
    scales = list(z.ticks=5,arrows=FALSE, col="black", font=10, tck=0.5),
    screen = list(z = 40, x = -75, y = 0))

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

The virtual keyword forces the compiler to pick the method implementation defined in the object's class rather than in the pointer's class.

Shape *shape = new Triangle(); 
cout << shape->getName();

In the above example, Shape::getName will be called by default, unless the getName() is defined as virtual in the Base class Shape. This forces the compiler to look for the getName() implementation in the Triangle class rather than in the Shape class.

The virtual table is the mechanism in which the compiler keeps track of the various virtual-method implementations of the subclasses. This is also called dynamic dispatch, and there is some overhead associated with it.

Finally, why is virtual even needed in C++, why not make it the default behavior like in Java?

1. C++ is based on the principles of "Zero Overhead" and "Pay for what you use". So it doesn't try to perform dynamic dispatch for you, unless you need it.
2. To provide more control to the interface. By making a function non-virtual, the interface/abstract class can control the behavior in all its implementations.

Sometimes that problem occurs if you already have a branch with the base name.

I tried this:

git checkout -b features/aName origin/features/aName

Unfortunately, I already had a branch named features, and I got the exception of the question asker.

Removing the branch features resolved the problem, the above command worked.

I dont know if you solved this issue, but i had same issue, if the instance is local you must check the permission to access the file, but if you are accessing from your computer to a server (remote access) you have to specify the path in the server, so that means to include the file in a server directory, that solved my case

example:

BULK INSERT Table
FROM 'C:\bulk\usuarios_prueba.csv' -- This is server path not local
WITH 
  (
     FIELDTERMINATOR =',',
     ROWTERMINATOR ='\n'
  );

a = ('A','B','C') # see it as the string "ABC" b = ('A','B','D')

A is converted to its corresponding ASCII ord('A') #65 same for other elements

So, >> a>b # True you can think of it as comparing between string (It is exactly, actually)

the same thing goes for integers too.

x = (1,2,2) # see it the string "123" y = (1,2,3) x > y # False

because (1 is not greater than 1, move to the next, 2 is not greater than 2, move to the next 2 is less than three -lexicographically -)

The key point is mentioned in the answer above

think of it as an element is before another alphabetically not element is greater than an element and in this case consider all the tuple elements as one string.

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

You may also want to make sure that your code localizes correctly, or make sure the users are used to the "international" notation. For example, "1,112" actually means different numbers across different countries. In Germany it means the number a little over one, instead of one thousand and something.

Corresponding Wikipedia article is at http://en.wikipedia.org/wiki/Decimal_mark. It seems to be poorly written at this time though. For example as a Chinese I'm not sure where does these description about thousand separator in China come from.

Your method (placing script before the closing body tag)

<script>
   myFunction()
</script>
</body>
</html>

is a reliable way to support old and new browsers.

Something like this should work unless I'm missing the point:

import json
import urllib2
json.load(urllib2.urlopen("url"))

You can't close an alert box with Javascript.

You could, however, use a window instead:

var w = window.open('','','width=100,height=100')
w.document.write('Message')
w.focus()
setTimeout(function() {w.close();}, 5000)

How about an approach that not only allows multiple domains, but allows dynamic domains.

The use case here is with a Sharepoint app part which loads our site inside of Sharepoint via an iframe. The problem is that sharepoint has dynamic subdomains such as https://yoursite.sharepoint.com. So for IE, we need to specify ALLOW-FROM https://.sharepoint.com

Tricky business, but we can get it done knowing two facts:

1. When an iframe loads, it only validates the X-Frame-Options on the first request. Once the iframe is loaded, you can navigate within the iframe and the header isn't checked on subsequent requests.

2. Also, when an iframe is loaded, the HTTP referer is the parent iframe url.

You can leverage these two facts server side. In ruby, I'm using the following code:

  uri = URI.parse(request.referer)
  if uri.host.match(/\.sharepoint\.com$/)
    url = "https://#{uri.host}"
    response.headers['X-Frame-Options'] = "ALLOW-FROM #{url}"
  end

Here we can dynamically allow domains based upon the parent domain. In this case, we ensure that the host ends in sharepoint.com keeping our site safe from clickjacking.

I'd love to hear feedback on this approach.
