If you stored the complete model, not only the weights, in the HDF5 file, then it is as simple as

from keras.models import load_model
model = load_model('model.h5')

It has been asked in the past, apparently it costs a lot to mobile browsers, so it's been disabled.

Check this comment by @PaulIrish:

Fixed-backgrounds have huge repaint cost and decimate scrolling performance, which is, I believe, why it was disabled.

you can see workarounds to this in this posts:

Fixed background image with ios7

Fixed body background scrolls with the page on iOS7

HTML:

<div class="foo">
    /* whatever is required */
</div>

CSS:

.foo {
    top: 0;
    transition: top ease 0.5s;
}

.foo:hover{
    top: -10px;
}

This is just a basic transition to ease the div tag up by 10px when it is hovered on. The transition property's values can be edited along with the class.hover properties to determine how the transition works.

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>

Static in Java:

Static is a Non Access Modifier. The static keyword belongs to the class than instance of the class. can be used to attach a Variable or Method to a Class.

Static keyword CAN be used with:

Method

Variable

Class nested within another Class

Initialization Block

CAN'T be used with:

Class (Not Nested)

Constructor

Interfaces

Method Local Inner Class(Difference then nested class)

Inner Class methods

Instance Variables

Local Variables

Example:

Imagine the following example which has an instance variable named count which in incremented in the constructor:

package pkg;

class StaticExample {
    int count = 0;// will get memory when instance is created

    StaticExample() {
        count++;
        System.out.println(count);
    }

    public static void main(String args[]) {

        StaticExample c1 = new StaticExample();
        StaticExample c2 = new StaticExample();
        StaticExample c3 = new StaticExample();

    }
}

Output:

1 1 1

Since instance variable gets the memory at the time of object creation, each object will have the copy of the instance variable, if it is incremented, it won't reflect to other objects.

Now if we change the instance variable count to a static one then the program will produce different output:

package pkg;

class StaticExample {
    static int count = 0;// will get memory when instance is created

    StaticExample() {
        count++;
        System.out.println(count);
    }

    public static void main(String args[]) {

        StaticExample c1 = new StaticExample();
        StaticExample c2 = new StaticExample();
        StaticExample c3 = new StaticExample();

    }
}

Output:

1 2 3

In this case static variable will get the memory only once, if any object changes the value of the static variable, it will retain its value.

Static with Final:

The global variable which is declared as final and static remains unchanged for the whole execution. Because, Static members are stored in the class memory and they are loaded only once in the whole execution. They are common to all objects of the class. If you declare static variables as final, any of the objects can’t change their value as it is final. Therefore, variables declared as final and static are sometimes referred to as Constants. All fields of interfaces are referred as constants, because they are final and static by default.

2.0 Compatible Answer: While above mentioned answer explain in detail on how to use GPU on Keras Model, I want to explain how it can be done for Tensorflow Version 2.0.

To know how many GPUs are available, we can use the below code:

print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

To find out which devices your operations and tensors are assigned to, put tf.debugging.set_log_device_placement(True) as the first statement of your program.

Enabling device placement logging causes any Tensor allocations or operations to be printed. For example, running the below code:

tf.debugging.set_log_device_placement(True)

# Create some tensors
a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
c = tf.matmul(a, b)

print(c)

gives the Output shown below:

Executing op MatMul in device /job:localhost/replica:0/task:0/device:GPU:0 tf.Tensor( [[22. 28.] [49. 64.]], shape=(2, 2), dtype=float32)

In my case I had a prefix that had to be added for each route in the group, otherwise response would be that the UserController class was not found.

Route::prefix('/user')->group(function() {
    Route::post('/login', [UserController::class, 'login'])->prefix('/user');
    Route::post('/register', [UserController::class, 'register'])->prefix('/user');
});

A cleaner way to handle file open/close and avoid memory leaks:

Prep:

import numpy as np
import h5py

data_to_write = np.random.random(size=(100,20)) # or some such

Write:

with h5py.File('name-of-file.h5', 'w') as hf:
    hf.create_dataset("name-of-dataset",  data=data_to_write)

Read:

with h5py.File('name-of-file.h5', 'r') as hf:
    data = hf['name-of-dataset'][:]

sys.exit(myString) doesn't mean "return this string". If you pass a string to sys.exit, sys.exit will consider that string to be an error message, and it will write that string to stderr. The closest concept to a return value for an entire program is its exit status, which must be an integer.

If you want to capture output written to stderr, you can do something like

python yourscript 2> return_file

You could do something like that in your bash script

output=$((your command here) 2> &1)

This is not guaranteed to capture only the value passed to sys.exit, though. Anything else written to stderr will also be captured, which might include logging output or stack traces.

example:

test.py

print "something"
exit('ohoh') 

t.sh

va=$(python test.py 2>&1)                                                                                                                    
mkdir $va

bash t.sh

edit

Not sure why but in that case, I would write a main script and two other scripts... Mixing python and bash is pointless unless you really need to.

import script1
import script2

if __name__ == '__main__':
    filename = script1.run(sys.args)
    script2.run(filename)

Beautiful Soup 4 supports most CSS selectors with the .select() method, therefore you can use an id selector such as:

soup.select('#articlebody')

If you need to specify the element's type, you can add a type selector before the id selector:

soup.select('div#articlebody')

The .select() method will return a collection of elements, which means that it would return the same results as the following .find_all() method example:

soup.find_all('div', id="articlebody")
# or
soup.find_all(id="articlebody")

If you only want to select a single element, then you could just use the .find() method:

soup.find('div', id="articlebody")
# or
soup.find(id="articlebody")

You need

$('selector').dialog('close');

For me, the carousel wasn't working in the DreamWeaver CC provided the code in the "template" page I am playing with. I needed to add the data-ride="carousel" attribute to the carousel div in order for it to start working. Thanks to Adarsh for his code snippet which highlighted the missing attribute.

No, the IEnumerable doesn't support adding items to it.

Your 'alternative' is:

var myList = new List(items);
myList.Add(otherItem);

Good day,

I know I am late to this party, but let me show you my answer.

const [windowSize, setWindowSize] = useState(null)

useEffect(() => {
    const handleResize = () => {
        setWindowSize(window.innerWidth)
    }

    window.addEventListener('resize', handleResize)

    return () => window.removeEventListener('resize', handleResize)
}, [])

You can't do that using open. use codecs.

when you are opening a file in python using the open built-in function you will always read/write the file in ascii. To write it in utf-8 try this:

import codecs
file = codecs.open('data.txt','w','utf-8')

One trick that makes position:absolute more palatable to me is to make its parent position:relative. Then the child will be 'absolute' relative to the position of the parent.

jsFiddle

If you want to add new items from another hash - use merge method:

hash = {:item1 => 1}
another_hash = {:item2 => 2, :item3 => 3}
hash.merge(another_hash) # {:item1=>1, :item2=>2, :item3=>3}

In your specific case it could be:

hash = {:item1 => 1}
hash.merge({:item2 => 2}) # {:item1=>1, :item2=>2}

but it's not wise to use it when you should to add just one element more.

Pay attention that merge will replace the values with the existing keys:

hash = {:item1 => 1}
hash.merge({:item1 => 2}) # {:item1=>2}

exactly like hash[:item1] = 2

Also you should pay attention that merge method (of course) doesn't effect the original value of hash variable - it returns a new merged hash. If you want to replace the value of the hash variable then use merge! instead:

hash = {:item1 => 1}
hash.merge!({:item2 => 2})
# now hash == {:item1=>1, :item2=>2}

getSupportFragmentManager().getFragments().get(viewPager.getCurrentItem());

Cast the instance retreived from above line to the fragment you want to work on with. Works perfectly fine.

viewPager

is the pager instance managing the fragments.

I had the same issue, but it was happening because my file was called "geo_data.csv.csv" - new laptop wasn't showing file extensions, so the name issue was invisible in Windows Explorer. Very silly, I know, but if this solution doesn't work for you, try that :-)

If you need to clean out all data, it might be faster to recreate collection, e.g.

solrctl --zk localhost:2181/solr collection --delete <collectionName>
solrctl --zk localhost:2181/solr collection --create <collectionName> -s 1

Use @@ROWCOUNT:

SELECT * FROM service s WHERE s.service_id = ?;

IF @@ROWCOUNT > 0 
   -- do stuff here.....

According to SQL Server Books Online:

Returns the number of rows affected by the last statement. If the number of rows is more than 2 billion, use ROWCOUNT_BIG.

Authentication - Are you the person you claim to be?

Authorization - Are you authorized to do whatever it is you're trying to do?

Example

A web app uses Google Sign-In. After a user successfully signs in, Google sends back:

1. A JWT token. This can be validated and decoded to get authentication information. Is the token signed by Google? What is the user's name and email?
2. An access token. This authorizes the web app to access Google APIs on behalf of the user. For example, can the app access the user's Google Calendar events? These permissions depend on the scopes that were requested, and whether or not the user allowed it.

Additionally:

The company may have an admin dashboard that allows customer support to manage the company's users. Instead of providing a custom signup solution that would allow customer support to access this dashboard, the company uses Google Sign-In.

The JWT token (received from the Google sign in process) is sent to the company's authorization server to figure out if the user has a G Suite account with the organization's hosted domain ([email protected])? And if they do, are they a member of the company's Google Group that was created for customer support? If yes to all of the above, we can consider them authenticated.

The company's authorization server then sends the dashboard app an access token. This access token can be used to make authorized requests to the company's resource server (e.g. ability to make a GET request to an endpoint that sends back all of the company's users).

To prefix a set of lines I use one of two different approaches:

One approach is the block select (mentioned by sth). In general, you can select a rectangular region with ctrl-V followed by cursor-movement. Once you've highlighted a rectangle, pressing shift-I will insert characters on the left side of the rectangle, or shift-A will append them on the right side of the rectangle. So you can use this technique to make a rectangle that includes the left-most column of the lines you want to prefix, hit shift-I, type the prefix, and then hit escape.

The other approach is to use a substitution (as mentioned by Brian Agnew). Brian's substitution will affect the entire file (the % in the command means "all lines"). To affect just a few lines the easiest approach is to hit shift-V (which enables visual-line mode) while on the first/last line, and then move to the last/first line. Then type:

:s/^/YOUR PREFIX/

The ^ is a regex (in this case, the beginning of the line). By typing this in visual line mode you'll see '<,'> inserted before the s automatically. This means the range of the substitution will be the visual selection.

Extra tip: if your prefix contains slashes, you can either escape them with backslash, or you can use a different punctuation character as the separator in the command. For example, to add C++ line comments, I usually write:

:s:^:// :

For adding a suffix the substitution approach is generally easier unless all of your lines are exactly the same length. Just use $ for the pattern instead of ^ and your string will be appended instead of pre-pended.

If you want to add a prefix and a suffix simultaneously, you can do something like this:

:s/.*/PREFIX & SUFFIX/

The .* matches the whole line. The & in the replacement puts the matched text (the whole line) back, but now it'll have your prefix and suffix added.

BTW: when commenting out code you'll probably want to uncomment it later. You can use visual-block (ctrl-V) to select the slashes and then hit d to delete them, or you can use a substitution (probably with a visual line selection, made with shift-V) to remove the leading slashes like this:

:s:// ::

<!DOCTYPE html>_x000D_
<html>_x000D_
  <head>_x000D_
    <title>Center</title>_x000D_
  </head>_x000D_
  <body>_x000D_
_x000D_
    <div style="text-align: center;">_x000D_
      <div style="width: 500px; margin: 0 auto; background: #000; color: #fff;">This DIV is centered</div>_x000D_

  </body>_x000D_
</html>

Tested and worked in IE, Firefox, Chrome, Safari and Opera. I did not test IE6. The outer text-align is needed for IE. Other browsers (and IE9?) will work when you give the DIV margin (left and right) value of auto. Margin "0 auto" is a shorthand for margin "0 auto 0 auto" (top right bottom left).

Note: the text is also centered inside the inner DIV, if you want it to remain on the left side just specify text-align: left; for the inner DIV.

Edit: IE 6, 7, 8 and 9 running on the Standards Mode will work with margins set to auto.

Be careful with arrays. We must write a checking variable after ?, because:

  $params = ['param1' => 'value1',
             'param2' => 'value2',
             'param3' => 'value3',];

  $param1 = isset($params['param1'])?:null;
  $param2 = !empty($params['param2'])?:null;
  $param3 = $params['param3']?:null; // get E_NOTICE, if $params['param3'] eq false

  var_dump($param1,$param2,$param3);
  true // would like to expect `value1`
  true // would like to expect `value2`
  param3 // properly, but problem above

Updated

From RFC. In PHP 7 the operator Null Coalesce Operator will do it, for example:

$param1 = $params['param1'] ?? null;
// Equivalent to:  $param1 = isset($params['param1']) ? $params['param1'] : null;

Or, have the DB automatically assign a constraint name using:

ALTER TABLE foo ADD UNIQUE (thecolumn);

Since Flask 0.10 you can`t add multiple routes to one endpoint. But you can add fake endpoint

   return show_with_username(userId)

@user.route('/<userId>/<username>')
def show_with_username(userId,username=None):
   pass

The socket file should be created automatically when the MySQL daemon starts.

If it isn't found, most likely the directory which is supposed to contain it doesn't exist, or some other file system problem is preventing the socket from being created.

To find out where the file should be, use:

% mysqld --verbose --help | grep ^socket

You can use psutil package:

Install

pip install psutil

for proc in psutil.process_iter():
    if process_name in proc.name():
       pid = proc.pid

To capitalize on the answer of Alex D, using refinements:

module CoreExtensions
  module Integerable
    refine String do
      def integer?
        Integer(self)
      rescue ArgumentError
        false
      else
        true
      end
    end
  end
end

Later, in you class:

require 'core_ext/string/integerable'

class MyClass
  using CoreExtensions::Integerable

  def method
    'my_string'.integer?
  end
end

It is my solution for that:

onDelete(id: number) {
    this.service.delete(id).then(() => {
        let index = this.documents.findIndex(d => d.id === id); //find index in your array
        this.documents.splice(index, 1);//remove element from array
    });

    event.stopPropagation();
}

The error can be caused by mixing together debug builds and release builds in same executable or dll.

1. in the vs configuration manager, are some of your projects in debug mode and some in release mode?
2. is one of your release projects has the preprocessor symbol DEBUG or _DEBUG defined?
3. is one of your debug projects has the preprocessor symbol NDEBUG defined?

To validate the problem has gone just repeat the operation involved in the license issue.

try:

parent.childNodes[1].style.color = "rgb(155, 102, 102)"; 

Or

parent.childNodes[1].style.color = "#"+(155).toString(16)+(102).toString(16)+(102).toString(16);

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:

This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.

tail -n 20 /var/log/apache2/error.log

There are situations when your pip doesn't get downloaded along with python installation. Even your whole script folder can be empty.

You can do so manually as well.

Just head to Command Prompt and type python -m ensurepip --default-pip Press Enter.

Make sure that value of path variable is updated.

This will do the Trick

Like already some answered before: The @ operator suppresses all errors in PHP, including notices, warnings and even critical errors.

BUT: Please, really do not use the @ operator at all.

Why?

Well, because when you use the @ operator for error supression, you have no clue at all where to start when an error occurs. I already had some "fun" with legacy code where some developers used the @ operator quite often. Especially in cases like file operations, network calls, etc. Those are all cases where lots of developers recommend the usage of the @ operator as this sometimes is out of scope when an error occurs here (for example a 3rdparty API could be unreachable, etc.).

But what's the point to still not use it? Let's have a look from two perspectives:

As a developer: When @ is used, I have absolutely no idea where to start. If there are hundreds or even thousands of function calls with @ the error could be like everyhwere. No reasonable debugging possible in this case. And even if it is just a 3rdparty error - then it's just fine and you're done fast. ;-) Moreover, it's better to add enough details to the error log, so developers are able to decide easily if a log entry is something that must be checked further or if it's just a 3rdparty failure that is out of the developer's scope.

As a user: Users don't care at all what the reason for an error is or not. Software is there for them to work, to finish a specific task, etc. They don't care if it's the developer's fault or a 3rdparty problem. Especially for the users, I strongly recommend to log all errors, even if they're out of scope. Maybe you'll notice that a specific API is offline frequently. What can you do? You can talk to your API partner and if they're not able to keep it stable, you should probably look for another partner.

In short: You should know that there exists something like @ (knowledge is always good), but just do not use it. Many developers (especially those debugging code from others) will be very thankful.

Apache commons-lang3 has StringUtils.repeat(String, int), with this one you can do (for simplicity, not with StringBuilder):

String original;
original = original + StringUtils.repeat("x", n);

Since it is open source, you can read how it is written. There is a minor optimalization for small n-s if I remember correctly, but most of the time it uses StringBuilder.

Variable that is not defined will cause compilation error.

What you're asking is about checking if it is initialized. But initialization is just a value, that you should choose and assign in the constructor.

For example:

class MyClass
{
    MyClass() : mCharacter('0'), mDecimal(-1.0){};
    void SomeMethod();

    char mCharacter;
    double mDecimal;
};

void MyClass::SomeMethod()
{
    if ( mCharacter != '0')
    {
        // touched after the constructor
        // do something with mCharacter.
    }

    if ( mDecimal != -1.0 )
    {
        // touched after the constructor
        // define mDecimal.
    }
}

You should initialize to a default value that will mean something in the context of your logic, of course.

A little clarity...

// Get a PropertyInfo of specific property type(T).GetProperty(....)
PropertyInfo propertyInfo;
propertyInfo = typeof(TypeWithTheStaticProperty)
    .GetProperty("NameOfStaticProperty", BindingFlags.Public | BindingFlags.Static); 

// Use the PropertyInfo to retrieve the value from the type by not passing in an instance
object value = propertyInfo.GetValue(null, null);

// Cast the value to the desired type
ExpectedType typedValue = (ExpectedType) value;

@Joao Marcos solution works for me but I had to modify the code to make it work on IE, below if what the code looks like

       downloadFile(url,filename) {
        var that = this;
        const extension =  url.split('/').pop().split('?')[0].split('.').pop();

        var req = new XMLHttpRequest();
        req.open("GET", url, true);
        req.responseType = "blob";
        req.onload = function (event) {
            const fileName = `${filename}.${extension}`;
            const blob = req.response;

            if (window.navigator.msSaveBlob) { // IE
                window.navigator.msSaveOrOpenBlob(blob, fileName);
            } 
            const link = document.createElement('a');
            link.href = window.URL.createObjectURL(blob);                
            link.download = fileName;
            link.click();
            URL.revokeObjectURL(link.href);

        };

        req.send();
    },

I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany to look at each item in each group.

I think you just want:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new ResultLine
            {
                ProductName = cl.First().Name,
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

The use of First() here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.

I'd also suggest that you should change the Quantity and Price properties to be int and decimal types respectively - why use a string property for data which is clearly not textual?

No, since the catches all refer to the same try block, so throwing from within a catch block would be caught by an enclosing try block (probably in the method that called this one)

void ExplodeString( const std::string& string, const char separator, std::list<int>& result ) {
    if( string.size() ) {
        std::string::const_iterator last = string.begin();
        for( std::string::const_iterator i=string.begin(); i!=string.end(); ++i ) {
            if( *i == separator ) {
                const std::string str(last,i);
                int id = atoi(str.c_str());
                result.push_back(id);
                last = i;
                ++ last;
            }
        }
        if( last != string.end() ) result.push_back( atoi(&*last) );
    }
}

I had a similar problem when I recreated my workspace that was fixed in the following way:

Go to Eclipse -> Preferences, under Java select "Installed JREs" and check one of the boxes to specify a default JRE. Click OK and then go back to your project's properties. Go to the "Java Build Path" section and choose the "Libraries" tab. Remove the unbound System Default library, then click the "Add Library" button. Select "JRE System Library" and you should be good to go!

I just didn't log out of root before running ./studio.sh All set.

Create a default struct as the other answers have mentioned:

struct MyStruct
{
    int flag;
}

MyStruct_default = {3};

However, the above code will not work in a header file - you will get error: multiple definition of 'MyStruct_default'. To solve this problem, use extern instead in the header file:

struct MyStruct
{
    int flag;
};

extern const struct MyStruct MyStruct_default;

And in the c file:

const struct MyStruct MyStruct_default = {3};

Hope this helps anyone having trouble with the header file.

add:

margin: 0 0 3px 0;

to your #access li and move

background: #0f84e8; /* Show a solid color for older browsers */

to the #access a and take out the border-bottom. Then it will work

If you work in PyCharm, check the Environmental variables for your Django server. You should specify the proper module.settings file

Depends what you want to do.

If what you want is to retrieve the bytes that are remaining (between position and limit), then what you have will work. You could also just do:

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()];
bb.get(b);

which is equivalent as per the ByteBuffer javadocs.

To read the files from src/resources folder then try this :

DataSource fds = new FileDataSource(getFileHandle("images/sample.jpeg"));

public static File getFileHandle(String fileName){
       return new File(YourClassName.class.getClassLoader().getResource(fileName).getFile());
}

in case of non static reference:

return new File(getClass().getClassLoader().getResource(fileName).getFile());

For Bootstrap 4.0 beta (and I assume this will stay for final) there is a change - be aware that the hidden classes were removed.

See the docs: https://getbootstrap.com/docs/4.0/utilities/display/

In order to hide the content on mobile and display on the bigger devices you have to use the following classes:

d-none d-sm-block

The first class set display none all across devices and the second one display it for devices "sm" up (you could use md, lg, etc. instead of sm if you want to show on different devices.

I suggest to read about that before migration:

https://getbootstrap.com/docs/4.0/migration/#responsive-utilities

There is another way which ignores all empty cells before a nonempty cell and selects the last empty cell from the end of the first column. Columns should be addressed with their number eg. Col "A" = 1.

With ThisWorkbook.Sheets("sheet1")

        .Cells(.Cells(.Cells.Rows.Count, 1).End(xlUp).Row + 1, 1).select

End With

The next code is exactly as the above but can be understood better.

i = ThisWorkbook.Sheets("sheet1").Cells.Rows.Count

j = ThisWorkbook.Sheets("sheet1").Cells(i, 1).End(xlUp).Row

ThisWorkbook.Sheets("sheet1").Cells(j + 1, 1) = textbox1.value

Note that you can only read a stream once, so in some cases, you may need to clone the response in order to repeatedly read it:

fetch('example.json')
  .then(res=>res.clone().json())
  .then( json => console.log(json))

fetch('url_that_returns_text')
  .then(res=>res.clone().text())
  .then( text => console.log(text))

I prepared my commit that I wanted to amend with an older one and was surprised to see that rebase -i complained that I have uncommitted changes. But I didn't want to make my changes again specifying edit option of the older commit. So the solution was pretty easy and straightforward:

1. prepare your update to older commit, add it and commit
2. git rebase -i <commit you want to amend>^ - notice the ^ so you see the said commit in the text editor

3. you will get sometihng like this:

   pick 8c83e24 use substitution instead of separate subsystems file to avoid jgroups.xml and jgroups-e2.xml going out of sync
   pick 799ce28 generate ec2 configuration out of subsystems-ha.xml and subsystems-full-ha.xml to avoid discrepancies
   pick e23d23a fix indentation of jgroups.xml
   

4. now to combine e23d23a with 8c83e24 you can change line order and use squash like this:

   pick 8c83e24 use substitution instead of separate subsystems file to avoid jgroups.xml and jgroups-e2.xml going out of sync    
   squash e23d23a fix indentation of jgroups.xml
   pick 799ce28 generate ec2 configuration out of subsystems-ha.xml and subsystems-full-ha.xml to avoid discrepancies
   

5. write and exit the file, you will be present with an editor to merge the commit messages. Do so and save/exit the text document

6. You are done, your commits are amended

The most effective one liner that

• returns a boolean (as opposed to Orbling's answer)
• Does not return a false positive when searching for thisClass on an element that has class="thisClass-suffix".
• is compatible with every browser down to at least IE6

function hasClass( target, className ) {
    return new RegExp('(\\s|^)' + className + '(\\s|$)').test(target.className);
}

@Manuel was part way there. You can add the compiler option as well, like this:

If you have CMake 3.1.0+, this becomes even easier:

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
target_link_libraries(my_app PRIVATE Threads::Threads)

If you are using CMake 2.8.12+, you can simplify this to:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  target_compile_options(my_app PUBLIC "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

Older CMake versions may require:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  set_property(TARGET my_app PROPERTY COMPILE_OPTIONS "-pthread")
  set_property(TARGET my_app PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

If you want to use one of the first two methods with CMake 3.1+, you will need set(THREADS_PREFER_PTHREAD_FLAG ON) there too.

Tacking on cryptic characters at the beginning of each variable name is unnecessary and shows that the variable name by itself isn't descriptive enough. Most languages require the variable type at declaration anyway, so that information is already available.

There's also the situation where, during maintenance, a variable type needs to change. Example: if a variable declared as "uint_16 u16foo" needs to become a 64-bit unsigned, one of two things will happen:

1. You'll go through and change each variable name (making sure not to hose any unrelated variables with the same name), or
2. Just change the type and not change the name, which will only cause confusion.

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

You can also use Bootstrap 4 flex classes

Like: .align-item-center and .justify-content-center

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

try:

RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

Where the folder you want to appear in the url is in the first part of the statement - this is what it will match against and the second part 'rewrites' it to your existing folder. the [NC] flag means that it will ignore case differences eg Apple/ will still forward.

See here for a tutorial: http://www.sitepoint.com/article/guide-url-rewriting/

There is also a nice test utility for windows you can download from here: http://www.helicontech.com/download/rxtest.zip Just to note for the tester you need to leave out the domain name - so the test would be against /folder1/login.php

to redirect from /folder1 to /apple try this:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]

to redirect and then rewrite just combine the above in the htaccess file:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]
RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

If you want to do it in XML, jus set paddingTopand paddingLeft to your RecyclerView and equal amount of layoutMarginBottom and layoutMarginRight to the item you inflate into your RecyclerView(or vice versa).

You can also cast (n,) to (n,1) by enclosing within brackets [ ].

e.g. Instead of np.append(b,a,axis=0) use np.append(b,[a],axis=0)

a=[1,2]
b=[[5,6],[7,8]]
np.append(b,[a],axis=0)

returns

array([[5, 6],
       [7, 8],
       [1, 2]])

1. The protocol is available as req.protocol. docs here

   1. Before express 3.0, the protocol you can assume to be http unless you see that req.get('X-Forwarded-Protocol') is set and has the value https, in which case you know that's your protocol

2. The host comes from req.get('host') as Gopal has indicated

3. Hopefully you don't need a non-standard port in your URLs, but if you did need to know it you'd have it in your application state because it's whatever you passed to app.listen at server startup time. However, in the case of local development on a non-standard port, Chrome seems to include the port in the host header so req.get('host') returns localhost:3000, for example. So at least for the cases of a production site on a standard port and browsing directly to your express app (without reverse proxy), the host header seems to do the right thing regarding the port in the URL.

4. The path comes from req.originalUrl (thanks @pgrassant). Note this DOES include the query string. docs here on req.url and req.originalUrl. Depending on what you intend to do with the URL, originalUrl may or may not be the correct value as compared to req.url.

Combine those all together to reconstruct the absolute URL.

  var fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;

If you use that forumla in the name manager you are creating a dynamic range which uses "this sheet" in place of a specific sheet.

As Jerry says, Sheet1!A1 refers to cell A1 on Sheet1. If you create a named range and omit the Sheet1 part you will reference cell A1 on the currently active sheet. (omitting the sheet reference and using it in a cell formula will error).

edit: my bad, I was using $A$1 which will lock it to the A1 cell as above, thanks pnuts :p

Use an relative path to the root of your site, for example:

If clock.js is on http://domain.com/javascript/clock.js

Include :

<script language="JavaScript" src="/javascript/clock.js"></script>

If it's on your domain root directory:

<script language="JavaScript" src="/clock.js"></script>

With PHP 5.6 on Amazon Linux (should be the same on RedHat or CentOS):

yum install php56-opcache

and then restart apache.

Best solution can be:

Add a string parameter in the existing job

Then in the Source Code Management section update Branches to build to use the string parameter you defined

If you see a checkbox labeled Lightweight checkout, make sure it is unchecked.

The configuration indicated in the images will tell the jenkins job to use master as the default branch, and for manual builds it will ask you to enter branch details (FYI: by default it's set to master)

In order to reduce crc32 to taking the reminder you need to:

1. Invert bits on each byte
2. xor first four bytes with 0xFF (this is to avoid errors on the leading 0s)
3. Add padding at the end (this is to make the last 4 bytes take part in the hash)
4. Compute the reminder
5. Reverse the bits again
6. xor the result again.

In code this is:

func CRC32 (file []byte) uint32 {
    for i , v := range(file) {
        file[i] = bits.Reverse8(v)
    }
    for i := 0; i < 4; i++ {
        file[i] ^= 0xFF
    }

    // Add padding
    file = append(file, []byte{0, 0, 0, 0}...)
    newReminder := bits.Reverse32(reminderIEEE(file))

    return newReminder ^ 0xFFFFFFFF
}

where reminderIEEE is the pure reminder on GF(2)[x]

Using HTTP status codes would be a RESTful way to do it, but that would suggest you make the rest of the interface RESTful using resource URIs and so on.

In truth, define the interface as you like (return an error object, for example, detailing the property with the error, and a chunk of HTML that explains it, etc), but once you've decided on something that works in a prototype, be ruthlessly consistent.

Here's an extremely simple CSV parser that handles quoted fields with commas, new lines, and escaped double quotation marks. There's no splitting or regular expression. It scans the input string 1-2 characters at a time and builds an array.

Test it at http://jsfiddle.net/vHKYH/.

function parseCSV(str) {
    var arr = [];
    var quote = false;  // 'true' means we're inside a quoted field

    // Iterate over each character, keep track of current row and column (of the returned array)
    for (var row = 0, col = 0, c = 0; c < str.length; c++) {
        var cc = str[c], nc = str[c+1];        // Current character, next character
        arr[row] = arr[row] || [];             // Create a new row if necessary
        arr[row][col] = arr[row][col] || '';   // Create a new column (start with empty string) if necessary

        // If the current character is a quotation mark, and we're inside a
        // quoted field, and the next character is also a quotation mark,
        // add a quotation mark to the current column and skip the next character
        if (cc == '"' && quote && nc == '"') { arr[row][col] += cc; ++c; continue; }

        // If it's just one quotation mark, begin/end quoted field
        if (cc == '"') { quote = !quote; continue; }

        // If it's a comma and we're not in a quoted field, move on to the next column
        if (cc == ',' && !quote) { ++col; continue; }

        // If it's a newline (CRLF) and we're not in a quoted field, skip the next character
        // and move on to the next row and move to column 0 of that new row
        if (cc == '\r' && nc == '\n' && !quote) { ++row; col = 0; ++c; continue; }

        // If it's a newline (LF or CR) and we're not in a quoted field,
        // move on to the next row and move to column 0 of that new row
        if (cc == '\n' && !quote) { ++row; col = 0; continue; }
        if (cc == '\r' && !quote) { ++row; col = 0; continue; }

        // Otherwise, append the current character to the current column
        arr[row][col] += cc;
    }
    return arr;
}

Laravel 4: Change "host" in the app/config/database.php file from "localhost" to "127.0.0.1"

Laravel 5+: Change "DB_HOST" in the .env file from "localhost" to "127.0.0.1"

I had the exact same problem. None of the above solutions worked for me. I solved the problem by changing the "host" in the /app/config/database.php file from "localhost" to "127.0.0.1".

Not sure why "localhost" doesn't work by default but I found this answer in a similar question solved in a symfony2 post. https://stackoverflow.com/a/9251924/1231563

Update: Some people have asked as to why this fix works so I have done a little bit of research into the topic. It seems as though they use different connection types as explained in this post https://stackoverflow.com/a/9715164/1231563

The issue that arose here is that "localhost" uses a UNIX socket and can not find the database in the standard directory. However "127.0.0.1" uses TCP (Transmission Control Protocol), which essentially means it runs through the "local internet" on your computer being much more reliable than the UNIX socket in this case.

The element.style property lets you know only the CSS properties that were defined as inline in that element (programmatically, or defined in the style attribute of the element), you should get the computed style.

Is not so easy to do it in a cross-browser way, IE has its own way, through the element.currentStyle property, and the DOM Level 2 standard way, implemented by other browsers is through the document.defaultView.getComputedStyle method.

The two ways have differences, for example, the IE element.currentStyle property expect that you access the CCS property names composed of two or more words in camelCase (e.g. maxHeight, fontSize, backgroundColor, etc), the standard way expects the properties with the words separated with dashes (e.g. max-height, font-size, background-color, etc).

Also, the IE element.currentStyle will return all the sizes in the unit that they were specified, (e.g. 12pt, 50%, 5em), the standard way will compute the actual size in pixels always.

I made some time ago a cross-browser function that allows you to get the computed styles in a cross-browser way:

function getStyle(el, styleProp) {
  var value, defaultView = (el.ownerDocument || document).defaultView;
  // W3C standard way:
  if (defaultView && defaultView.getComputedStyle) {
    // sanitize property name to css notation
    // (hypen separated words eg. font-Size)
    styleProp = styleProp.replace(/([A-Z])/g, "-$1").toLowerCase();
    return defaultView.getComputedStyle(el, null).getPropertyValue(styleProp);
  } else if (el.currentStyle) { // IE
    // sanitize property name to camelCase
    styleProp = styleProp.replace(/\-(\w)/g, function(str, letter) {
      return letter.toUpperCase();
    });
    value = el.currentStyle[styleProp];
    // convert other units to pixels on IE
    if (/^\d+(em|pt|%|ex)?$/i.test(value)) { 
      return (function(value) {
        var oldLeft = el.style.left, oldRsLeft = el.runtimeStyle.left;
        el.runtimeStyle.left = el.currentStyle.left;
        el.style.left = value || 0;
        value = el.style.pixelLeft + "px";
        el.style.left = oldLeft;
        el.runtimeStyle.left = oldRsLeft;
        return value;
      })(value);
    }
    return value;

The above function is not perfect for some cases, for example for colors, the standard method will return colors in the rgb(...) notation, on IE they will return them as they were defined.

I'm currently working on an article in the subject, you can follow the changes I make to this function here.

Add my two cents here. If you want to get user.name or user.email only without verbose output.

On liunx, type git config --list | grep user.name.

On windows, type git config --list | findstr user.name.

This will give you user.name only.

Please call trigger function any where and button will click.

<a href="#" id="myBtn" title="" >Button click </a>

function trigger(){
    document.getElementById("myBtn").click();
}

This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.

Although you've attempted to do so:

private Guid _id;
[Key]
public Guid ID
{
    get { return _id; }
}

This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits record from the database, it constructs a Fruit object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.

You need Entity Framework to be able to set the value of ID. This means the property needs to have a setter.

I had the same problem, the WebBrowser was using an old version of IE, with some googling I came across the following code that makes a change into registry and makes the WebBrowser to use the lastest IE version possible:

 public enum BrowserEmulationVersion
    {
        Default = 0,
        Version7 = 7000,
        Version8 = 8000,
        Version8Standards = 8888,
        Version9 = 9000,
        Version9Standards = 9999,
        Version10 = 10000,
        Version10Standards = 10001,
        Version11 = 11000,
        Version11Edge = 11001
    }

You just need to create a class and put this code in it, then run the following code when the program starts:

 if (!WBEmulator.IsBrowserEmulationSet())

You may use it like:

    WBEmulator.SetBrowserEmulationVersion()

You can use a LinearLayout instead of using Button it's an arrangement i used in my app

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:background="@color/mainColor"
        android:orientation="horizontal"
        android:padding="10dp">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@drawable/ic_cv"
            android:textColor="@color/offBack"
            android:textSize="20dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:text="@string/cartyCv"
            android:textColor="@color/offBack"
            android:textSize="25dp" />

    </LinearLayout>

• In your app.component.html use:

    [ngStyle]="{'background-color':backcolor}"
  

• In app.ts declare variable of string type backcolor:string.

• Set the variable this.backcolor="red".

Not tested but should work

 products.sort((a,b)=>a.title.rendered > b.title.rendered)

var filenameText = findViewById(R.id.filename) as EditText
filenameText.addTextChangedListener(object : TextWatcher {
    override fun afterTextChanged(s: Editable?) {
        filename = filenameText.text.toString()
        Log.i("FileName: ", filename)
    }
    
    override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {}
    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {}
})

Adding;

display: inline-block;

to the child elements will prevent them being split between columns.

use get_loaded_extensions() PHP function

Actually you do not need to use delegate keyword. Just pass lambda as parameter:

control.Invoke((MethodInvoker)(() => {this.Text = "Hi"; }));

as long as you did not commit you can type

git merge --abort

just as the command line suggested.

In Windows 10 I had to run the batch file as an administrator.

Guess I'm too late...

Came across the same problem today; here is my solution using FileSystemObject:

Dim objFSO
Const ForReading = 1
Const ForWriting = 2
Dim objTS 'define a TextStream object
Dim strContents As String
Dim fileSpec As String

fileSpec = "C:\Temp\test.txt"
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTS = objFSO.OpenTextFile(fileSpec, ForReading)
strContents = objTS.ReadAll
strContents = Replace(strContents, "XXXXX", "YYYY")
objTS.Close

Set objTS = objFSO.OpenTextFile(fileSpec, ForWriting)
objTS.Write strContents
objTS.Close

One thing to watch out for though, particularly if you are using a framework, is to check if the application is regenerating session ids between requests - anything that depends explicitly on the session id will run into problems, although obviously the rest of the data in the session will unaffected.

If the application is regenerating session ids like this then you can end up with a situation where an ajax request in effect invalidates / replaces the session id in the requesting page.

With pure javascript you can do the following:

var buttons = document.getElementsByTagName("button");
var buttonsCount = buttons.length;
for (var i = 0; i < buttonsCount; i += 1) {
    buttons[i].onclick = function(e) {
        alert(this.id);
    };
}?

try this

let when = DispatchTime.now() + 1.5
    DispatchQueue.main.asyncAfter(deadline: when) {
        //some code
    }

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

for(int i=0; i<arr.length; i++){
  arr[i] = i;
}

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2
  3
  4
Array 1
  5
  6
  7
  8
  9
Array 2
  10

So, strictly speaking, the "type of a variable" is always present, and can be passed around as a type parameter. For example:

val x = 5
def f[T](v: T) = v
f(x) // T is Int, the type of x

But depending on what you want to do, that won't help you. For instance, may want not to know what is the type of the variable, but to know if the type of the value is some specific type, such as this:

val x: Any = 5
def f[T](v: T) = v match {
  case _: Int    => "Int"
  case _: String => "String"
  case _         => "Unknown"
}
f(x)

Here it doesn't matter what is the type of the variable, Any. What matters, what is checked is the type of 5, the value. In fact, T is useless -- you might as well have written it def f(v: Any) instead. Also, this uses either ClassTag or a value's Class, which are explained below, and cannot check the type parameters of a type: you can check whether something is a List[_] (List of something), but not whether it is, for example, a List[Int] or List[String].

Another possibility is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag or a TypeTag. For example:

val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(implicit ev: ClassTag[T]) = ev.toString
f(x) // returns the string "Any"

A ClassTag will also let you use type parameters you received on match. This won't work:

def f[A, B](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}

But this will:

val x = 'c'
val y = 5
val z: Any = 5
import scala.reflect.ClassTag
def f[A, B: ClassTag](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}
f(x, y) // A (Char) is not a B (Int)
f(x, z) // A (Char) is a B (Any)

Here I'm using the context bounds syntax, B : ClassTag, which works just like the implicit parameter in the previous ClassTag example, but uses an anonymous variable.

One can also get a ClassTag from a value's Class, like this:

val x: Any = 5
val y = 5
import scala.reflect.ClassTag
def f(a: Any, b: Any) = {
  val B = ClassTag(b.getClass)
  ClassTag(a.getClass) match {
    case B => "a is the same class as b"
    case _ => "a is not the same class as b"
  }
}
f(x, y) == f(y, x) // true, a is the same class as b

A ClassTag is limited in that it only covers the base class, but not its type parameters. That is, the ClassTag for List[Int] and List[String] is the same, List. If you need type parameters, then you must use a TypeTag instead. A TypeTag however, cannot be obtained from a value, nor can it be used on a pattern match, due to JVM's erasure.

Examples with TypeTag can get quite complex -- not even comparing two type tags is not exactly simple, as can be seen below:

import scala.reflect.runtime.universe.TypeTag
def f[A, B](a: A, b: B)(implicit evA: TypeTag[A], evB: TypeTag[B]) = evA == evB
type X = Int
val x: X = 5
val y = 5
f(x, y) // false, X is not the same type as Int

Of course, there are ways to make that comparison return true, but it would require a few book chapters to really cover TypeTag, so I'll stop here.

Finally, maybe you don't care about the type of the variable at all. Maybe you just want to know what is the class of a value, in which case the answer is rather simple:

val x = 5
x.getClass // int -- technically, an Int cannot be a class, but Scala fakes it

It would be better, however, to be more specific about what you want to accomplish, so that the answer can be more to the point.

To paraphrase, you can rename it with the .command extension or create an AppleScript to run the shell.

React Native

These steps solved my problem:

• Renaming of ReactNativeApp/android/build directory to old.build
• Closing Android Studio
• Inside ReactNativeApp/android executed this command. gradlew clean
• Making sure my RAM is 1500mb free
• Then finally executing the command react-native run-android

** It's quite interesting to close Android Studio. But beleive me these steps solved my problem **

PHP way:

if (in_array('a', ['a', 'b', 'c'])) {
   // do something if true
}

My solution in JS:

if (['a', 'b', 'c'].includes('a')) {
   // do something if true
}

Coming long after, but none of the answers here are entirely correct.

When drawn on a canvas, the passed image is uncompressed + all pre-multiplied.
When exported, its uncompressed or recompressed with a different algorithm, and un-multiplied.

All browsers and devices will have different rounding errors happening in this process
(see Canvas fingerprinting).

So if one wants a base64 version of an image file, they have to request it again (most of the time it will come from cache) but this time as a Blob.

Then you can use a FileReader to read it either as an ArrayBuffer, or as a dataURL.

function toDataURL(url, callback){_x000D_
    var xhr = new XMLHttpRequest();_x000D_
    xhr.open('get', url);_x000D_
    xhr.responseType = 'blob';_x000D_
    xhr.onload = function(){_x000D_
      var fr = new FileReader();_x000D_
    _x000D_
      fr.onload = function(){_x000D_
        callback(this.result);_x000D_
      };_x000D_
    _x000D_
      fr.readAsDataURL(xhr.response); // async call_x000D_
    };_x000D_
    _x000D_
    xhr.send();_x000D_
}_x000D_
_x000D_
toDataURL(myImage.src, function(dataURL){_x000D_
  result.src = dataURL;_x000D_
_x000D_
  // now just to show that passing to a canvas doesn't hold the same results_x000D_
  var canvas = document.createElement('canvas');_x000D_
  canvas.width = myImage.naturalWidth;_x000D_
  canvas.height = myImage.naturalHeight;_x000D_
  canvas.getContext('2d').drawImage(myImage, 0,0);_x000D_
_x000D_
  console.log(canvas.toDataURL() === dataURL); // false - not same data_x000D_
  });

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

Reassign the variable to a substring:

s = s.substring(0, s.length() - 1)

Also an alternative way of solving your problem: you might also want to consider using a StringTokenizer to read the file and set the delimiters to be the characters you don't want to be part of words.

Depends on your requirment, but the most effective way to create is:

 Product obj = new Product
            {
                ID = 21,
                Price = 200,
                Category = "XY",
                Name = "SKR",
            };

Example:

$test = "chees";
"${test}y";

It will output:

cheesy

It is exactly what you are looking for.

Java actually has no modulo operator the way C does. % in Java is a remainder operator. On positive integers, it works exactly like modulo, but it works differently on negative integers and, unlike modulo, can work with floating point numbers as well. Still, it's rare to use % on anything but positive integers, so if you want to call it a modulo, then feel free!

These posts helped me get past a couple of issues I had creating a CLR Stored Procedure with Restful API call against Infor M3 API.

The XML Result from these API's look like this for my code below:

miResult xmlns="http://lawson.com/m3/miaccess">
    <Program>MMS200MI</Program>
    <Transaction>Get</Transaction>
    <Metadata>...</Metadata>
    <MIRecord>
        <RowIndex>0</RowIndex>
        <NameValue>
            <Name>STAT</Name>
            <Value>20</Value>
        </NameValue>
        <NameValue>
            <Name>ITNO</Name>
            <Value>ITEM123</Value>
        </NameValue>
        <NameValue>
            <Name>ITDS</Name>
            <Value>ITEM DESCRIPTION 123 </Value>
        </NameValue>
...

The CLR C# Code to accomplish listing out the Resultset from the API works as shown below:

Hopefully this provides helpful.

I was in a similar problem than you. I need to lock device orientation for some screens (like Login) and allow rotation in others.

After a few changes and following some answers below I did it by:

• Enabling all the orientations in the Project's Info.plist.

• Disabling orientation in those ViewControllers where I need the device not to rotate, like in the Login screen in my case. I needed to override shouldAutorotate method in this VC:

-(BOOL)shouldAutorotate{ return NO; }

Hope this will work for you.

Go on using tabTextAppearance as you did but

1) to fix the capital letter side effect add textAllCap in your style :

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
    <item name="android:textSize">14sp</item>
    <item name="android:textAllCaps">true</item>
</style>

2) to fix the selected tab color side effect add in TabLayout xml the following library attributes :

app:tabSelectedTextColor="@color/color1"
app:tabTextColor="@color/color2" 

Hope this helps.

No, it is not possible to seed Math.random(), but it's fairly easy to write your own generator, or better yet, use an existing one.

Check out: this related question.

Also, see David Bau's blog for more information on seeding.

Just porting over the Java from Compute hex color code for an arbitrary string to Javascript:

function hashCode(str) { // java String#hashCode
    var hash = 0;
    for (var i = 0; i < str.length; i++) {
       hash = str.charCodeAt(i) + ((hash << 5) - hash);
    }
    return hash;
} 

function intToRGB(i){
    var c = (i & 0x00FFFFFF)
        .toString(16)
        .toUpperCase();

    return "00000".substring(0, 6 - c.length) + c;
}

To convert you would do:

intToRGB(hashCode(your_string))

You have included the dependency for sflj's api, but not the dependency for the implementation of the api, that is a separate jar, you could try slf4j-simple-1.6.1.jar.

You can't use forward declaration with the typedef struct.

The struct itself is an anonymous type, so you don't have an actual name to forward declare.

typedef struct{
    int one;
    int two;
} myStruct;

A forward declaration like this won't work:

struct myStruct; //forward declaration fails

void blah(myStruct* pStruct);

//error C2371: 'myStruct' : redefinition; different basic types

If you're using jQuery UI too, you can do like this:

var e = jQuery.Event("keypress");
e.keyCode = $.ui.keyCode.ENTER;
$("input").trigger(e);

In SQL Server 2008 you can use

http://www.sommarskog.se/share_data.html#tableparam

or else simple and same as common execution

CREATE PROCEDURE OrderSummary @MaxQuantity INT OUTPUT AS

SELECT Ord.EmployeeID, SummSales = SUM(OrDet.UnitPrice * OrDet.Quantity)
FROM Orders AS Ord
     JOIN [Order Details] AS OrDet ON (Ord.OrderID = OrDet.OrderID)
GROUP BY Ord.EmployeeID
ORDER BY Ord.EmployeeID

SELECT @MaxQuantity = MAX(Quantity) FROM [Order Details]

RETURN (SELECT SUM(Quantity) FROM [Order Details])
GO

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

I have also faced this problem and the solution is:

1. open Solution Explore
2. double click on Program.cs file

I added this code again and my program ran accurately:

Application.Run(new PayrollSystem()); 
//File name this code removed by me accidentally.

A short way to run 'em all:

[first_function, ..., nth_function].forEach (function(f) {
    f('a string');
}); 

Here you could find the CA certs with instructions to download and convert Mozilla CA certs. Once you get ca-bundle.crt or cacert.pem you just use:

Alternative to @HostListener and scroll output on the element I would suggest using fromEvent from RxJS since you can chain it with filter() and distinctUntilChanges() and can easily skip flood of potentially redundant events (and change detections).

Here is a simple example:

// {static: true} can be omitted if you don't need this element/listener in ngOnInit
@ViewChild('elementId', {static: true}) el: ElementRef;

// ...

fromEvent(this.el.nativeElement, 'scroll')
  .pipe(
    // Is elementId scrolled for more than 50 from top?
    map((e: Event) => (e.srcElement as Element).scrollTop > 50),
    // Dispatch change only if result from map above is different from previous result
    distinctUntilChanged());

The query component is indicated by the first ? in a URI. "Query string" might be a synonym (this term is not used in the URI standard).

Some examples for HTTP URIs with query components:

http://example.com/foo?bar
http://example.com/foo/foo/foo?bar/bar/bar
http://example.com/?bar
http://example.com/?@bar._=???/1:
http://example.com/?bar1=a&bar2=b

(list of allowed characters in the query component)

The "format" of the query component is up to the URI authors. A common convention (but nothing more than a convention, as far as the URI standard is concerned¹) is to use the query component for key-value pairs, aka. parameters, like in the last example above: bar1=a&bar2=b.

Such parameters could also appear in the other URI components, i.e., the path² and the fragment. As far as the URI standard is concerned, it’s up to you which component and which format to use.

Example URI with parameters in the path, the query, and the fragment:

http://example.com/foo;key1=value1?key2=value2#key3=value3

¹ The URI standard says about the query component:

[…] query components are often used to carry identifying information in the form of "key=value" pairs […]

² The URI standard says about the path component:

[…] the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes.

I don't want to suggest a product out of turn, since getting Intellisense running is probably the best option, but I've struggled with the accursed no intellisense on Management Studio for months. Reinstallation, CU7 update, refreshing caches, sacrificing chickens to pagan gods; nothing has helped.

I was about to pay for RedGate's SqlPrompt (pretty damned pricey, $195 US), when I found SqlComplete.

http://www.devart.com/dbforge/sql/sqlcomplete/?gclid=CN2xs_Lw7akCFcYZHAodpicXXw

There is a free version which does the basics, and the full version is only $50!

I'm a database architect, and while I can remember the commands, auto complete saves me heaps of time. If you're stuck and can't get Intellisense to work, try SqlComplete. It saved me hours of hassle.

No, it is like I want to run Form_Load of Form A,if it is possible

-- Varun Mahajan

The usual way to do this is to put the relevant code in a procedure that can be called by both forms. It is best put the code in a standard module, but you could have it on Form a:

Form B:

Sub RunFormALoad()
   Forms!FormA.ToDoOnLoad
End Sub

Form A:

Public Sub Form_Load()
    ToDoOnLoad
End Sub    

Sub ToDoOnLoad()
    txtText = "Hi"
End Sub

No, It is not possible. I think you can use ng-init as hack http://docs.angularjs.org/api/ng.directive:ngInit.

Some applications launches themselves by protocols. like itunes with "itms://" links. I don't know however how you can register that with windows.

You can use slice() for this:

>> foo = [1,2,3,4,5,6]
=> [1, 2, 3, 4, 5, 6]
>> bar = [10,20,30,40,50,60]
=> [10, 20, 30, 40, 50, 60]
>> half = foo.length / 2
=> 3
>> foobar = foo.slice(0, half) + bar.slice(half, foo.length)
=> [1, 2, 3, 40, 50, 60]

By the way, to the best of my knowledge, Python "lists" are just efficiently implemented dynamically growing arrays. Insertion at the beginning is in O(n), insertion at the end is amortized O(1), random access is O(1).

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

Use svcutil.exe with the /sc switch to generate the WCF contracts. This will create a code file that you can add to your project. It will contain all interfaces and data types you need to create your service. Change the output location using the /o switch, or you can find the file in the folder where you ran svcutil.exe. The default language is C# but I think (I've never tried it) you should be able to change this using /l:vb.

svcutil /sc "WSDL file path"

If your WSDL has any supporting XSD files pass those in as arguments after the WSDL.

svcutil /sc "WSDL file path" "XSD 1 file path" "XSD 2 file path" ... "XSD n file path"

Then create a new class that is your service and implement the contract interface you just created.

For people using Google Cloud Platform, any error will stop the import process. Personally I encountered two different errors depending on the pg_dump command I issued :

1- The input is a PostgreSQL custom-format dump. Use the pg_restore command-line client to restore this dump to a database.

Occurs when you've tried to dump your DB in a non plain text format. I.e when the command lacks the -Fp or --format=plain parameter. However, if you add it to your command, you may then encounter the following error :

2- SET SET SET SET SET SET CREATE EXTENSION ERROR: must be owner of extension plpgsql

This is a permission issue I have been unable to fix using the command provided in the GCP docs, the tips from this current thread, or following advice from Google Postgres team here. Which recommended to issue the following command :

pg_dump -Fp --no-acl --no-owner -U myusername myDBName > mydump.sql

The only thing that did the trick in my case was manually editing the dump file and commenting out all commands relating to plpgsql.

I hope this helps GCP-reliant souls.

Update :

It's easier to dump the file commenting out extensions, especially since some dumps can be huge : pg_dump ... | grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' > mydump.sql

Which can be narrowed down to plpgsql : pg_dump ... | grep -v -E '(CREATE\ EXTENSION\ IF\ NOT\ EXISTS\ plpgsql|COMMENT\ ON\ EXTENSION\ plpgsql)' > mydump.sql

You shouldn't rely on the order of elements by using prev or next. Just use the for attribute of the label, as it should correspond to the ID of the element you're currently manipulating:

var label = $("label[for='" + $(this).attr('id') + "']");

However, there are some cases where the label will not have for set, in which case the label will be the parent of its associated control. To find it in both cases, you can use a variation of the following:

var label = $('label[for="' + $(this).attr('id') + '"]');

if(label.length <= 0) {
    var parentElem = $(this).parent(),
        parentTagName = parentElem.get(0).tagName.toLowerCase();

    if(parentTagName == "label") {
        label = parentElem;
    }
}

I hope this helps!

You can do it like below in SQL Server

ALTER TABLE one
ADD two_id int foreign key
REFERENCES two(id)

       jenkins.exe stop
       jenkins.exe start
       jenkins.exe restart

These commands will work from cmd only if you run CMD with admin permissions

I solved the Access-Control-Allow-Origin error modifying the dataType parameter to dataType:'jsonp' and adding a crossDomain:true

$.ajax({

    url: 'https://www.googleapis.com/moderator/v1/series?key='+key,
    data: myData,
    type: 'GET',
    crossDomain: true,
    dataType: 'jsonp',
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); },
    beforeSend: setHeader
});

You can do the following

foreach (var it in someCollection.Select((x, i) => new { Value = x, Index = i }) )
{
   if (it.Index > SomeNumber) //      
}

This will create an anonymous type value for every entry in the collection. It will have two properties

• Value: with the original value in the collection
• Index: with the index within the collection

The name of the Series becomes the index of the row in the DataFrame:

In [99]: df = pd.DataFrame(np.random.randn(8, 4), columns=['A','B','C','D'])

In [100]: s = df.xs(3)

In [101]: s.name = 10

In [102]: df.append(s)
Out[102]: 
           A         B         C         D
0  -2.083321 -0.153749  0.174436  1.081056
1  -1.026692  1.495850 -0.025245 -0.171046
2   0.072272  1.218376  1.433281  0.747815
3  -0.940552  0.853073 -0.134842 -0.277135
4   0.478302 -0.599752 -0.080577  0.468618
5   2.609004 -1.679299 -1.593016  1.172298
6  -0.201605  0.406925  1.983177  0.012030
7   1.158530 -2.240124  0.851323 -0.240378
10 -0.940552  0.853073 -0.134842 -0.277135

You can get column type of DataTable with DataType attribute of datatable column like below:

var type = dt.Columns[0].DataType

dt : DataTable object.

0 : DataTable column index.

Hope It Helps

There is now an ELMAH.MVC package in NuGet that includes an improved solution by Atif and also a controller that handles the elmah interface within MVC routing (no need to use that axd anymore)
The problem with that solution (and with all the ones here) is that one way or another the elmah error handler is actually handling the error, ignoring what you might want to set up as a customError tag or through ErrorHandler or your own error handler
The best solution IMHO is to create a filter that will act at the end of all the other filters and log the events that have been handled already. The elmah module should take care of loging the other errors that are unhandled by the application. This will also allow you to use the health monitor and all the other modules that can be added to asp.net to look at error events

I wrote this looking with reflector at the ErrorHandler inside elmah.mvc

public class ElmahMVCErrorFilter : IExceptionFilter
{
   private static ErrorFilterConfiguration _config;

   public void OnException(ExceptionContext context)
   {
       if (context.ExceptionHandled) //The unhandled ones will be picked by the elmah module
       {
           var e = context.Exception;
           var context2 = context.HttpContext.ApplicationInstance.Context;
           //TODO: Add additional variables to context.HttpContext.Request.ServerVariables for both handled and unhandled exceptions
           if ((context2 == null) || (!_RaiseErrorSignal(e, context2) && !_IsFiltered(e, context2)))
           {
            _LogException(e, context2);
           }
       }
   }

   private static bool _IsFiltered(System.Exception e, System.Web.HttpContext context)
   {
       if (_config == null)
       {
           _config = (context.GetSection("elmah/errorFilter") as ErrorFilterConfiguration) ?? new ErrorFilterConfiguration();
       }
       var context2 = new ErrorFilterModule.AssertionHelperContext((System.Exception)e, context);
       return _config.Assertion.Test(context2);
   }

   private static void _LogException(System.Exception e, System.Web.HttpContext context)
   {
       ErrorLog.GetDefault((System.Web.HttpContext)context).Log(new Elmah.Error((System.Exception)e, (System.Web.HttpContext)context));
   }


   private static bool _RaiseErrorSignal(System.Exception e, System.Web.HttpContext context)
   {
       var signal = ErrorSignal.FromContext((System.Web.HttpContext)context);
       if (signal == null)
       {
           return false;
       }
       signal.Raise((System.Exception)e, (System.Web.HttpContext)context);
       return true;
   }
}

Now, in your filter config you want to do something like this:

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        //These filters should go at the end of the pipeline, add all error handlers before
        filters.Add(new ElmahMVCErrorFilter());
    }

Notice that I left a comment there to remind people that if they want to add a global filter that will actually handle the exception it should go BEFORE this last filter, otherwise you run into the case where the unhandled exception will be ignored by the ElmahMVCErrorFilter because it hasn't been handled and it should be loged by the Elmah module but then the next filter marks the exception as handled and the module ignores it, resulting on the exception never making it into elmah.

Now, make sure the appsettings for elmah in your webconfig look something like this:

<add key="elmah.mvc.disableHandler" value="false" /> <!-- This handles elmah controller pages, if disabled elmah pages will not work -->
<add key="elmah.mvc.disableHandleErrorFilter" value="true" /> <!-- This uses the default filter for elmah, set to disabled to use our own -->
<add key="elmah.mvc.requiresAuthentication" value="false" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.allowedRoles" value="*" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.route" value="errortracking" /> <!-- Base route for elmah pages -->

The important one here is "elmah.mvc.disableHandleErrorFilter", if this is false it will use the handler inside elmah.mvc that will actually handle the exception by using the default HandleErrorHandler that will ignore your customError settings

This setup allows you to set your own ErrorHandler tags in classes and views, while still loging those errors through the ElmahMVCErrorFilter, adding a customError configuration to your web.config through the elmah module, even writing your own Error Handlers. The only thing you need to do is remember to not add any filters that will actually handle the error before the elmah filter we've written. And I forgot to mention: no duplicates in elmah.

as of now, with win 1909 and using Git-2.24.0.2-64-bit installer the process is very friendly towards user configuration. Seems like the earlier problems may now be catered for.

There is one possible pitfall with using textBoxName.Text = string.Empty; and that is if you are using Text binding for your TextBox (i.e. <TextBox Text="{Binding Path=Description}"></TextBox>). In this case, setting an empty string will actually override and break your binding.

To prevent this behavior you have to use the Clear method:

textBoxName.Clear();

This way the TextBox will be cleared, but the binding will be kept intact.

Trivial example with an Animal and Dog: You mirror C++'s vtable mechanism (largely anyway). You also separate allocation and instantiation (Animal_Alloc, Animal_New) so we don't call malloc() multiple times. We must also explicitly pass the this pointer around.

If you were to do non-virtual functions, that's trival. You just don't add them to the vtable and static functions don't require a this pointer. Multiple inheritance generally requires multiple vtables to resolve ambiguities.

Also, you should be able to use setjmp/longjmp to do exception handling.

struct Animal_Vtable{
    typedef void (*Walk_Fun)(struct Animal *a_This);
    typedef struct Animal * (*Dtor_Fun)(struct Animal *a_This);

    Walk_Fun Walk;
    Dtor_Fun Dtor;
};

struct Animal{
    Animal_Vtable vtable;

    char *Name;
};

struct Dog{
    Animal_Vtable vtable;

    char *Name; // Mirror member variables for easy access
    char *Type;
};

void Animal_Walk(struct Animal *a_This){
    printf("Animal (%s) walking\n", a_This->Name);
}

struct Animal* Animal_Dtor(struct Animal *a_This){
    printf("animal::dtor\n");
    return a_This;
}

Animal *Animal_Alloc(){
    return (Animal*)malloc(sizeof(Animal));
}

Animal *Animal_New(Animal *a_Animal){
    a_Animal->vtable.Walk = Animal_Walk;
    a_Animal->vtable.Dtor = Animal_Dtor;
    a_Animal->Name = "Anonymous";
    return a_Animal;
}

void Animal_Free(Animal *a_This){
    a_This->vtable.Dtor(a_This);

    free(a_This);
}

void Dog_Walk(struct Dog *a_This){
    printf("Dog walking %s (%s)\n", a_This->Type, a_This->Name);
}

Dog* Dog_Dtor(struct Dog *a_This){
    // Explicit call to parent destructor
    Animal_Dtor((Animal*)a_This);

    printf("dog::dtor\n");

    return a_This;
}

Dog *Dog_Alloc(){
    return (Dog*)malloc(sizeof(Dog));
}

Dog *Dog_New(Dog *a_Dog){
    // Explict call to parent constructor
    Animal_New((Animal*)a_Dog);

    a_Dog->Type = "Dog type";
    a_Dog->vtable.Walk = (Animal_Vtable::Walk_Fun) Dog_Walk;
    a_Dog->vtable.Dtor = (Animal_Vtable::Dtor_Fun) Dog_Dtor;

    return a_Dog;
}

int main(int argc, char **argv){
    /*
      Base class:

        Animal *a_Animal = Animal_New(Animal_Alloc());
    */
    Animal *a_Animal = (Animal*)Dog_New(Dog_Alloc());

    a_Animal->vtable.Walk(a_Animal);

    Animal_Free(a_Animal);
}

PS. This is tested on a C++ compiler, but it should be easy to make it work on a C compiler.

That entity is converted to the char it represents when the browser renders the page. JS (jQuery) reads the rendered page, thus it will not encounter such a text sequence. The only way it could encounter such a thing is if you're double encoding entities.

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

Just to augment the other answers from a different angle.

If you want to reuse hashcode(s) from 'above' and derive new ones using your class' immutatable state, then a call to super will work. While this may/may not cascade all the way up to Object (i.e. some ancestor may not call super), it will allow you to derive hashcodes by reuse.

@Override
public int hashCode() {
    int ancestorHash = super.hashCode();
    // now derive new hash from ancestorHash plus immutable instance vars (id fields)
}

int is a primitive, null is not a value that it can take on. You could change the method return type to return java.lang.Integer and then you can return null, and existing code that returns int will get autoboxed.

Nulls are assigned only to reference types, it means the reference doesn't point to anything. Primitives are not reference types, they are values, so they are never set to null.

Using the object wrapper java.lang.Integer as the return value means you are passing back an Object and the object reference can be null.

Take a closer look at the ?axis documentation. If you look at the description of the labels argument, you'll see that it is:

"a logical value specifying whether (numerical) annotations are 
to be made at the tickmarks,"

So, just change it to true, and you'll get your tick labels.

x <- seq(10,200,10)
y <- runif(x)
plot(x,y,xaxt='n')
axis(side = 1, at = x,labels = T)
# Since TRUE is the default for labels, you can just use axis(side=1,at=x)

Be careful that if you don't stretch your window width, then R might not be able to write all your labels in. Play with the window width and you'll see what I mean.

It's too bad that you had such trouble finding documentation! What were your search terms? Try typing r axis into Google, and the first link you will get is that Quick R page that I mentioned earlier. Scroll down to "Axes", and you'll get a very nice little guide on how to do it. You should probably check there first for any plotting questions, it will be faster than waiting for a SO reply.

I use something like this (you should add code to deal with the various fails):

    var response = RunTaskWithTimeout<ReturnType>(
        (Func<ReturnType>)delegate { return SomeMethod(someInput); }, 30);


    /// <summary>
    /// Generic method to run a task on a background thread with a specific timeout, if the task fails,
    /// notifies a user
    /// </summary>
    /// <typeparam name="T">Return type of function</typeparam>
    /// <param name="TaskAction">Function delegate for task to perform</param>
    /// <param name="TimeoutSeconds">Time to allow before task times out</param>
    /// <returns></returns>
    private T RunTaskWithTimeout<T>(Func<T> TaskAction, int TimeoutSeconds)
    {
        Task<T> backgroundTask;

        try
        {
            backgroundTask = Task.Factory.StartNew(TaskAction);
            backgroundTask.Wait(new TimeSpan(0, 0, TimeoutSeconds));
        }
        catch (AggregateException ex)
        {
            // task failed
            var failMessage = ex.Flatten().InnerException.Message);
            return default(T);
        }
        catch (Exception ex)
        {
            // task failed
            var failMessage = ex.Message;
            return default(T);
        }

        if (!backgroundTask.IsCompleted)
        {
            // task timed out
            return default(T);
        }

        // task succeeded
        return backgroundTask.Result;
    }

My solution, in case someone finds it useful.

In Web.config:

<system.web>
    <customErrors mode="On" defaultRedirect="Error" >
      <error statusCode="404" redirect="~/Error/PageNotFound"/>
    </customErrors>
    ...
</system.web>

In Controllers/ErrorController.cs:

public class ErrorController : Controller
{
    public ActionResult PageNotFound()
    {
        if(Request.IsAjaxRequest()) {
            Response.StatusCode = (int)HttpStatusCode.NotFound;
            return Content("Not Found", "text/plain");
        }

        return View();
    }
}

Add a PageNotFound.cshtml in the Shared folder, and that's it.

An alternate solution of @kender

import os
os.path.dirname(os.path.normpath(yourpath))

where yourpath is the path you want the parent for.

But this solution is not perfect, since it will not handle the case where yourpath is an empty string, or a dot.

This other solution will handle more nicely this corner case:

import os
os.path.normpath(os.path.join(yourpath, os.pardir))

Here the outputs for every case that can find (Input path is relative):

os.path.dirname(os.path.normpath('a/b/'))          => 'a'
os.path.normpath(os.path.join('a/b/', os.pardir))  => 'a'

os.path.dirname(os.path.normpath('a/b'))           => 'a'
os.path.normpath(os.path.join('a/b', os.pardir))   => 'a'

os.path.dirname(os.path.normpath('a/'))            => ''
os.path.normpath(os.path.join('a/', os.pardir))    => '.'

os.path.dirname(os.path.normpath('a'))             => ''
os.path.normpath(os.path.join('a', os.pardir))     => '.'

os.path.dirname(os.path.normpath('.'))             => ''
os.path.normpath(os.path.join('.', os.pardir))     => '..'

os.path.dirname(os.path.normpath(''))              => ''
os.path.normpath(os.path.join('', os.pardir))      => '..'

os.path.dirname(os.path.normpath('..'))            => ''
os.path.normpath(os.path.join('..', os.pardir))    => '../..'

Input path is absolute (Linux path):

os.path.dirname(os.path.normpath('/a/b'))          => '/a'
os.path.normpath(os.path.join('/a/b', os.pardir))  => '/a'

os.path.dirname(os.path.normpath('/a'))            => '/'
os.path.normpath(os.path.join('/a', os.pardir))    => '/'

os.path.dirname(os.path.normpath('/'))             => '/'
os.path.normpath(os.path.join('/', os.pardir))     => '/'

though this question had a solution already, I just want to share mine to make it be cleared, hope it could help:

/* 
 * The root cause is method doesn't in the App's context 
 * so that it can't access other attributes of "this".
 * Below are few ways to define App's method property
 */
class App extends React.Component {
  constructor() {
     this.sayHi = 'hello';
     // create method inside constructor, context = this
     this.method = ()=> {  console.log(this.sayHi) };

     // bind method1 in constructor into context 'this'
     this.method1 = this.method.bind(this)
  }

  // method1 was defined here
  method1() {
      console.log(this.sayHi);
  }

  // create method property by arrow function. I recommend this.
  method2 = () => {
      console.log(this.sayHi);
  }
   render() {
   //....
   }
}

The accepted answer is a bad idea in general because the manually created make.exe will stick around and can potentially cause unexpected problems. It actually breaks RubyInstaller: https://github.com/oneclick/rubyinstaller2/issues/105

An alternative is installing make via Chocolatey (as pointed out by @Vasantha Ganesh K)

Another alternative is installing MSYS2 from Chocolatey and using make from C:\tools\msys64\usr\bin. If make isn't installed automatically with MSYS2 you need to install it manually via pacman -S make (as pointed out by @Thad Guidry and @Luke).

I found a better way to render razor view page when I got error with the methods above, this solution for both web form environment and mvc environment. No controller is needed.

Here is the code example, in this example I simulated a mvc action with an async http handler:

    /// <summary>
    /// Enables processing of HTTP Web requests asynchronously by a custom HttpHandler that implements the IHttpHandler interface.
    /// </summary>
    /// <param name="context">An HttpContext object that provides references to the intrinsic server objects.</param>
    /// <returns>The task to complete the http request.</returns>
    protected override async Task ProcessRequestAsync(HttpContext context)
    {
        if (this._view == null)
        {
            this.OnError(context, new FileNotFoundException("Can not find the mvc view file.".Localize()));
            return;
        }
        object model = await this.LoadModelAsync(context);
        WebPageBase page = WebPageBase.CreateInstanceFromVirtualPath(this._view.VirtualPath);
        using (StringWriter sw = new StringWriter())
        {
            page.ExecutePageHierarchy(new WebPageContext(new HttpContextWrapper(context), page, model), sw);
            await context.Response.Output.WriteAsync(sw.GetStringBuilder().ToString());
        }
    }

Personally, I needed a little hand holding figuring out how to use this and it is really, awesome.

IF(OBJECT_ID('tempdb..#TEMP') IS NOT NULL) BEGIN DROP TABLE #TEMP END
        SELECT *
            INTO #TEMP
            FROM (
            The query you want to use many times
            ) AS X

SELECT * FROM #TEMP WHERE THIS = THAT
SELECT * FROM #TEMP WHERE THIS <> THAT
SELECT COL1,COL3 FROM #TEMP WHERE THIS > THAT

DROP TABLE #TEMP

I needed to completely remove the Bootstrap responsive feature, i ended up overriding the behavior with the following snippet:

.container {
    width: 960px !important;
}

@media (min-width: 1px) {
  .container {
    max-width: 940px;
  }
  .col-lg-1,
  .col-lg-2,
[...]

Another solution is to use an SVG text node which is supported by most browsers.

<svg width="50" height="300">
    <text x="28" y="150" transform="rotate(-90, 28, 150)" style="text-anchor:middle; font-size:14px">This text is vertical</text>
</svg>

Demo: https://jsfiddle.net/bkymb5kr/

Had the same problem, Uninstall Genymotion, install VirtualBox stand alone from https://www.virtualbox.org/wiki/Downloads then install the Genymotion package without VirtualBox.

You can simply use this bootstrap helper to dialogs (only 5 kB)

it has support for ajax request, iframes, common dialogs, confirm and prompt!

you can use it as:

eModal.iframe('http://someUrl.com', 'This is a tile for iframe', callbackIfNeeded);

eModal.alert('The message', 'This title');

eModal.ajax('/mypage.html', 'This is a ajax', callbackIfNeeded);

eModal.confirm('the question', 'The title', theMandatoryCallback);

eModal.prompt('Form question', 'This is a ajax', theMandatoryCallback);

this provide a loading progress while loading the iframe!

No html required.

You can use a object literal as parameter to extra options.

For an attribute value that needs to be interpolated in a directive that is not using an isolated scope, e.g.,

<input my-directive value="{{1+1}}">

use Attributes' method $observe:

myApp.directive('myDirective', function () {
  return function (scope, element, attr) {
    attr.$observe('value', function(actual_value) {
      element.val("value = "+ actual_value);
    })
 }
});

From the directive page,

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

If the attribute value is just a constant, e.g.,

<input my-directive value="123">

you can use $eval if the value is a number or boolean, and you want the correct type:

return function (scope, element, attr) {
   var number = scope.$eval(attr.value);
   console.log(number, number + 1);
});

If the attribute value is a string constant, or you want the value to be string type in your directive, you can access it directly:

return function (scope, element, attr) {
   var str = attr.value;
   console.log(str, str + " more");
});

In your case, however, since you want to support interpolated values and constants, use $observe.

You have to use .values for arrays. for example say you have dataframe which has a column name ie, test['Name'], you can do

if name in test['Name'].values :
   print(name)

for a normal list you dont have to use .values

Just for a quick fix, try wrapping your child elements into a div element like this -

<div id="outer">
   <div class="divadjust" style="padding-top: 1px">
      <div id="inner">
         Hello world!
      </div>
   </div>
</div>

Margin of inner div won't collapse due to the padding of 1px in-between outer and inner div. So logically you will have 1px extra space along with existing margin of inner div.

The Chromatable jquery plugin allows a fixed header (or top row) with widths that allow percentages--granted, only a percentage of 100%.

http://www.chromaloop.com/posts/chromatable-jquery-plugin

I can't think of how you could do this without javascript.

update: new link -> http://www.jquery-plugins.info/chromatable-00012248.htm

There are definitely different ways to do this depending on your needs.

One way I use a UI-updating thread (that's not the main UI thread) is to have the thread start a loop where the entire logical processing loop is invoked onto the UI thread.

Example:

public SomeFunction()
{
    bool working = true;
    Thread t = new Thread(() =>
    {
        // Don't put the working bool in here, otherwise it will 
        // belong to the new thread and not the main UI thread.
        while (working)
        {
            Application.Current.Dispatcher.Invoke(() =>
            {
                // Put your entire logic code in here.
                // All of this code will process on the main UI thread because
                //  of the Invoke.
                // By doing it this way, you don't have to worry about Invoking individual
                //  elements as they are needed.
            });
        }
    });
}

With this, code executes entirely on main UI thread. This can be a pro for amateur programmers that have difficulty wrapping their heads around cross-threaded operations. However, it can easily become a con with more complex UIs (especially if performing animations). Really, this is only to fake a system of updating the UI and then returning to handle any events that have fired in lieu of efficient cross-threading operations.

Also be careful how you execute the js on the page. For example if you do something like this:

(function(window, document, undefined){

  var foo = document.getElementById("foo");

  console.log(foo);

})(window, document, undefined); 

This will return null because you'd be calling the document before it was loaded.

Better option..

(function(window, document, undefined){

// code that should be taken care of right away

window.onload = init;

  function init(){
    // the code to be called when the dom has loaded
    // #document has its nodes
  }

})(window, document, undefined);

You can add JavaScript code in an HTML document by employing the dedicated HTML tag <script> that wraps around JavaScript code.

The <script> tag can be placed in the <head> section of your HTML, in the <body> section, or after the </body> close tag, depending on when you want the JavaScript to load.

Generally, JavaScript code can go inside of the document <head> section in order to keep them contained and out of the main content of your HTML document.

However, if your script needs to run at a certain point within a page’s layout — like when using document.write to generate content — you should put it at the point where it should be called, usually within the <body> section.

So it would become:

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
    Iterator<Integer> myListIterator = myCoords.iterator(); 
    while (myListIterator.hasNext()) {
        Integer coord = myListIterator.next();    
        System.out.print("\r" + coord);
        try{
    Thread.sleep(2000);
  }catch(Exception e){
   // handle the exception...
  }
    }
}

X.each_with_index do |item, index|
  puts "current_index: #{index}"
end

This is one of the fundamentals of both languages that pointers evaluate to a type and value that can be used as a control expression, bool in C++ and int in C. Just use it.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.

import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;

public class JAXBUtils
{
    /**
     * Unmarshal an XML string

"foreach" is not the name for bash. It is simply "for". You can do things in one line only like:

for fn in `cat filenames.txt`; do cat "$fn"; done

I was having this issue because gradle and Android Studio were using a different path for the jvm. In the Event Log there was an option for AS and gradle to use the same path. Selecting this and then doing an invalidate cache & restart resolved the issue for me.

If you just want a file without revision information use

svn export <URL>

Adding to @pranay-rana's list:

Third way is:

function passFromValue(){
    var x = 15;
    return x;  
}
function passToValue() {
    var y = passFromValue();
    console.log(y);//15
}
passToValue(); 

If your goal is to find CSS selectors you can use MRI (once MRI is open, click any element to see various selectors for the element):

You can use a for loop. but don't forget the last char must be a null character !

char * msg = new char[65546];
for(int i=0;i<65545;i++)
{
    msg[i]='0';
}
msg[65545]='\0';

My problem was solved by the following command

sudo apt-get install php5-mcrypt

I have

• PHP 5.3.10-1ubuntu3.4 with Suhosin-Patch (cli)
• Ubuntu Desktop 12.04
• Mysql 5.5

below will work with any previously pushed revision, not only HEAD

for abbreviated revision hash:

git log -1 --pretty=format:%h

for long revision hash:

git log -1 --pretty=format:%H

(new Date().toString()).replace(/ \w+-\d+ \(.*\)$/,"")

This will have output: Tue Jul 10 2018 19:07:11

(new Date("2005-07-08T11:22:33+0000").toString()).replace(/ \w+-\d+ \(.*\)$/,"")

This will have output: Fri Jul 08 2005 04:22:33

Note: The time returned will depend on your local timezone

This is all that is needed:

<activity android:windowSoftInputMode="adjustResize"> </activity>

Assuming you're talking about master and on that respective branch (that said, this could be any working branch you're concerned with):

# Reset local master branch to November 3rd commit ID
git reset --hard 0d1d7fc32e5a947fbd92ee598033d85bfc445a50

# Reset remote master branch to November 3rd commit ID
git push -f origin 0d1d7fc32e5a947fbd92ee598033d85bfc445a50:master

I found the answer from in a blog post (now no longer exists)

Note that this is Resetting and Forcing the change to the remote, so that if others on your team have already git pulled, you will cause problems for them. You are destroying the change history, which is an important reason why people use git in the first place.

Better to use revert (see other answers) than reset. If you're a one man team then it probably doesn't matter.

Position absolute, top:0 and bottom:0 for the sidebar and position relative for the wrapper (or container) witch content all the elements and it's done !

Since Java7 you can simply use FileNameExtensionFilter(String description, String... extensions)

A simple JFileChooser analog to the example would be:

JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new FileNameExtensionFilter("Text files", "txt"));

I know the question was answered long ago, but this is actually the simplest solution.

This problem occured for me one time when I had already opened the built-in Android Emulator (AVD). Check if you turned off it before start changing anything in settings.

In Kotlin extension function can be used. This can only be used from code, not xml.

fun TextView.underline() {
    paintFlags = paintFlags or Paint.UNDERLINE_TEXT_FLAG
}

Usage:

 tv_change_number.underline()
 tv_resend_otp.underline()

I am a happy boost user and would certainly use Andreas' solution. But if you didn't have access to the boost libs you can use the stream library:

ifstream file(argv[1]);
if (!file)
{
    // Can't open file
}

It's not quite as nice as boost::filesystem::exists since the file will actually be opened...but then that's usually the next thing you want to do anyway.

If one is on a Windows machine and in PowerShell, one needs to quote the argument such as:

git stash apply "stash@{0}"

...or to apply the changes and remove from the stash:

git stash pop "stash@{0}"

Otherwise without the quotes you might get this error:

fatal: ambiguous argument 'stash@': unknown revision or path not in the working tree.

I just clicked on the debug icon and it started working.

Mac OS Mojave

The accepted answer no longer works. When running the command xcode-select --install it tells you to use "Software Update" to install updates.

In this link is the updated method:

Open a Terminal and then:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

This will open an installation Wizard.

Update 12/2019

After updating to Mojave 10.15.1 it seems that using xcode-select --install works as intended.

I was using jruby, in my case I created under config/initializers

postgres_driver.rb

$CLASSPATH << '~/.rbenv/versions/jruby-1.7.17/lib/ruby/gems/shared/gems/jdbc-postgres-9.4.1200/lib/postgresql-9.4-1200.jdbc4.jar'

or wherever your driver is, and that's it !

Why not one more answer? setState() and the setState()-triggered render() have both completed executing when you call componentDidMount() (the first time render() is executed) and/or componentDidUpdate() (any time after render() is executed). (Links are to ReactJS.org docs.)

Example with componentDidUpdate()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>;
this.parent.setState({'data':'hello!'});

Render parent...

componentDidMount() {           // componentDidMount() gets called after first state set
    console.log(this.state.data);   // output: "hello!"
}
componentDidUpdate() {          // componentDidUpdate() gets called after all other states set
    console.log(this.state.data);   // output: "hello!"
}

Example with componentDidMount()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>
this.parent.setState({'data':'hello!'});

Render parent...

render() {              // render() gets called anytime setState() is called
    return (
        <ChildComponent
            state={this.state}
        />
    );
}

After parent rerenders child, see state in componentDidUpdate().

componentDidMount() {           // componentDidMount() gets called anytime setState()/render() finish
console.log(this.props.state.data); // output: "hello!"
}

Could anyone help explain why

In Python 2 a python "int" was equivalent to a C long. In Python 3 an "int" is an arbitrary precision type but numpy still uses "int" it to represent the C type "long" when creating arrays.

The size of a C long is platform dependent. On windows it is always 32-bit. On unix-like systems it is normally 32 bit on 32 bit systems and 64 bit on 64 bit systems.

or give a solution for the code on windows? Thanks so much!

Choose a data type whose size is not platform dependent. You can find the list at https://docs.scipy.org/doc/numpy/reference/arrays.scalars.html#arrays-scalars-built-in the most sensible choice would probably be np.int64

In MATLAB R2015a or newer, it is no longer necessary (or advisable from a performance standpoint) to use fspecial followed by imfilter since there is a new function called imgaussfilt that performs this operation in one step and more efficiently.

The basic syntax:

B = imgaussfilt(A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma.

The size of the filter for a given Gaussian standard deviation (sigam) is chosen automatically, but can also be specified manually:

B = imgaussfilt(A,sigma,'FilterSize',[3 3]);

The default is 2*ceil(2*sigma)+1.

Additional features of imgaussfilter are ability to operate on gpuArrays, filtering in frequency or spacial domain, and advanced image padding options. It looks a lot like IPP... hmmm. Plus, there's a 3D version called imgaussfilt3.

you really should try to use jQuery in a separate file, not inline. Here is what you need:

<a class="notificationClose "><img src="close.png"/></a>

And then this at the bottom of your page in <script> tags at the very least or in a external JavaScript file.

$(".notificationClose").click(function() {
    $("#notification").fadeOut("normal", function() {
        $(this).remove();
    });
});

Another way to accomplish this is with the jq "--arg" flag. Using the original example:

#!/bin/sh

#this works ***
projectID=$(cat file.json | jq -r '.resource[] | 
select(.username=="[email protected]") | .id')
echo "$projectID"

[email protected]

# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[] 
| select(.username=="$EMAILID") | .id')
echo "$projectID"

See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626

You don't necessarily have to use custom CSS (or even worse inline CSS), in Bootstrap 4 you can use the utility classes for colors, like:

<div class="jumbotron bg-dark text-white">
...

And if you need other colors than the default ones, just add additional bg-classes using the same naming convention. This keeps the code neat and understandable.

You might also need to set text-white on child-elements inside the jumbotron, like headings.

Beautiful! Your solution was 99%... instead of "this.scrollY", I used "$(window).scrollTop()". What's even better is that this solution only requires the jQuery1.2.6 library (no additional libraries needed).

The reason I wanted that version in particular is because that's what ships with MVC currently.

Here's the code:

$(document).ready(function() {
    $("#topBar").css("position", "absolute");
});

$(window).scroll(function() {
    $("#topBar").css("top", $(window).scrollTop() + "px");
});
