Look at the types of those properties:

In [1]: import datetime

In [2]: d = datetime.date.today()

In [3]: type(d.month)
Out[3]: <type 'int'>

In [4]: type(d.day)
Out[4]: <type 'int'>

Both are integers. So there is no automatic way to do what you want. So in the narrow sense, the answer to your question is no.

If you want leading zeroes, you'll have to format them one way or another. For that you have several options:

In [5]: '{:02d}'.format(d.month)
Out[5]: '03'

In [6]: '%02d' % d.month
Out[6]: '03'

In [7]: d.strftime('%m')
Out[7]: '03'

In [8]: f'{d.month:02d}'
Out[8]: '03'

var date = new Date(date_string); var milliseconds = date.getTime();

This worked for me!

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

I solved this problem without deleting any keys. Here's how:

1. My device was connected to my computer via USB
2. I made sure Eclipse and android device monitor weren't running.
3. Typed at the commandline prompt: adb kill-server
4. Typed at the commandline prompt: adb start-server
5. After adb was restarted, I got a prompt on my device to authorize which I allowed.

Add $i = 1; after /* Servers configuration */

in place of $i = 0 in your phpmyadmin config.inc.php file

Running XAMPP on local windows server, my mysql data files are not under the usual install path (C:\Xampp), but on another disk.

So now I have the phpmyadmin tables with the double __ like pma__table... and $i = 1;

Not the place to give a complete tutorial, but here it is in short;

RewriteCond basically means "execute the next RewriteRule only if this is true". The !-l path is the condition that the request is not for a link (! means not, -l means link)

The RewriteRule basically means that if the request is done that matches ^(.+)$ (matches any URL except the server root), it will be rewritten as index.php?url=$1 which means a request for ollewill be rewritten as index.php?url=olle).

QSA means that if there's a query string passed with the original URL, it will be appended to the rewrite (olle?p=1 will be rewritten as index.php?url=olle&p=1.

L means if the rule matches, don't process any more RewriteRules below this one.

For more complete info on this, follow the links above. The rewrite support can be a bit hard to grasp, but there are quite a few examples on stackoverflow to learn from.

do it the simpler way,

direc=$(basename `pwd`)

Or use the shell

Read this article for better insight. Note: Numpy reports the shape of 3D arrays in the order layers, rows, columns.

mV.erase(it); 

If the class is marked final, it means that the class' structure can't be modified by anything external. Where this is the most visible is when you're doing traditional polymorphic inheritance, basically class B extends A just won't work. It's basically a way to protect some parts of your code (to extent).

To clarify, marking class final doesn't mark its fields as final and as such doesn't protect the object properties but the actual class structure instead.

Closest you'd get to a struct is an object with all members public.

class MyStruct {
    public $foo;
    public $bar;
}

$obj = new MyStruct();
$obj->foo = 'Hello';
$obj->bar = 'World';

I'd say looking at the PHP Class Documentation would be worth it. If you need a one-off struct, use the StdObject as mentioned in alex's answer.

L for Linux operating system A for apache web server M for Mysql database p for php for scripting and php modules

We can host php programs and cgi programs in LAMP system.

eg: In ubuntu apt-get install apache2 for web server apt-get install mysql-server php5-mysql for database and php apt-get install php5 and got to your web server http://localhost

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

if __name__ == '__main__':
    Example().main()

But you really shouldn't be using a class just to run your main code.

NSDate actually represents a time interval in seconds since a reference date (1st Jan 2000 UTC I think). Internally, a double precision floating point number is used so two arbitrary dates are highly unlikely to compare equal even if they are on the same day. If you want to see if a particular date falls on a particular day, you probably need to use NSDateComponents. e.g.

NSDateComponents* dateComponents = [[NSDateComponents alloc] init];
[dateComponents setYear: 2011];
[dateComponents setMonth: 5];
[dateComponents setDay: 24];
/*
 *  Construct two dates that bracket the day you are checking.  
 *  Use the user's current calendar.  I think this takes care of things like daylight saving time.
 */
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDate* startOfDate = [calendar dateFromComponents: dateComponents];
NSDateComponents* oneDay = [[NSDateComponents alloc] init];
[oneDay setDay: 1];
NSDate* endOfDate = [calendar dateByAddingComponents: oneDay toDate: startOfDate options: 0];
/*
 *  Compare the date with the start of the day and the end of the day.
 */
NSComparisonResult startCompare = [startOfDate compare: myDate];
NSComparisonResult endCompare = [endOfDate compare: myDate];

if (startCompare != NSOrderedDescending && endCompare == NSOrderedDescending)
{
    // we are on the right date
} 

You're not parsing a string, you're parsing an already-parsed object :)

var obj1 = JSON.parse('{"creditBalance":0,...,"starStatus":false}');
//                    ^                                          ^
//                    if you want to parse, the input should be a string 

var obj2 = {"creditBalance":0,...,"starStatus":false};
// or just use it directly.

lambda lst: reduce(lambda a,b:(b,b==a[0] and a[1]), lst, (lst[0], True))[1]

The next one will short short circuit:

all(itertools.imap(lambda i:yourlist[i]==yourlist[i+1], xrange(len(yourlist)-1)))

Also check that

<modules>
      <remove name="FormsAuthentication"/>
</modules>

If you found anything like this just remove:

<remove name="FormsAuthentication"/>

Line from web.config and here you go it will work fine I have tested it.

have you tried display:inline-block;?

Yes, you can, provided your JavaScript code is embedded into a PHP file.

You can use the os Module:

var os = require("os");
os.hostname();

See http://nodejs.org/docs/latest/api/os.html#os_os_hostname

Caveats:

1. if you can work with the IP address -- Machines may have several Network Cards and unless you specify it node will listen on all of them, so you don't know on which NIC the request came in, before it comes in.

2. Hostname is a DNS matter -- Don't forget that several DNS aliases can point to the same machine.

The sum function only gets the total of a column. In order to sum two values from different columns, convert the values to int and add them up using the +-Operator

Select (convert(int, col1)+convert(int, col2)) as summed from tbl1

Hope that helps.

From http://groups.google.com/group/jquery-dev/msg/2e0b7435a864beea:

$('#myform')[0].reset();

setting myinput.val('') might not emulate "reset" 100% if you have an input like this:

<input name="percent" value="50"/>

Eg calling myinput.val('') on an input with a default value of 50 would set it to an empty string, whereas calling myform.reset() would reset it to its initial value of 50.

You can also use:

<button onClick={()=>this.delta()}>+</button>

Or:

<button onClick={event=>this.delta(event)}>+</button>

If you are passing some params..

I don't have enough points to comment on an answer, but I wanted to say that mikec's answer worked for me except that I had to change it to return !isScrollable like so:

mScroller.setOnTouchListener(new OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {
      return !isScrollable;
    }
});

I came across the same issue of this question...

Wondering myself about it, I did a small alias function inside my .bashrc file:

        git pull -p
        printf "\n"
    done
    echo "Done"
}

1. download latest pytz file (pytz-2019.3.tar.gz) from:

   https://pypi.org/simple/pytz/

3. in cmd go to the extracted folder and run:

   python setup.py install
   

4. TIME_ZONE = 'Etc/GMT+2' or country name

sys.argv[1] contains the first command line argument passed to your script.

For example, if your script is named hello.py and you issue:

$ python3.1 hello.py foo

or:

$ chmod +x hello.py  # make script executable
$ ./hello.py foo

Your script will print:

Hello there foo

String[] is an array of Strings. Such an array is internally a class. Like all classes that don't explicitly extend some other class, it extends Object implicitly. The method toString() of class Object, by default, gives you the representation you see: the class name, followed by @, followed by the hash code in hex. Since the String[] class doesn't override the toString() method, you get that as a result.

Create some method that outputs the array elements for you. Iterate over the array and use System.out.print() (not print*ln*) on the elements.

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

Here's a variation of Shiv Kumar's answer, using Newtonsoft.Json (aka Json.NET):

public static bool SendAnSMSMessage(string message)
{
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
    httpWebRequest.ContentType = "text/json";
    httpWebRequest.Method = "POST";

    var serializer = new Newtonsoft.Json.JsonSerializer();
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        using (var tw = new Newtonsoft.Json.JsonTextWriter(streamWriter))
        {
             serializer.Serialize(tw, 
                 new {method= "send",
                      @params = new string[]{
                          "IPutAGuidHere", 
                          "[email protected]",
                          "MyTenDigitNumberWasHere",
                          message
                      }});
        }
    }
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var responseText = streamReader.ReadToEnd();
        //Now you have your response.
        //or false depending on information in the response
        return true;        
    }
}

if you are using http get please remove this line

rsync is not necessarily more efficient, due to the more detailed inventory of files and blocks it performs. The algorithm is fantastic at what it does, but you need to understand your problem to know if it is really going to be the best choice.

On a very large file system (say many thousands or millions of files) where files tend to be added but not updated, "cp -u" will likely be more efficient. cp makes the decision to copy solely on metadata and can simply get to the business of copying.

Note that you might want some buffering, e.g. by using tar rather than straight cp, depending on the size of the files, network performance, other disk activity, etc. I find the following idea very useful:

tar cf - . | tar xCf directory -

Metadata itself may actually become a significant overhead on very large (cluster) file systems, but rsync and cp will share this problem.

rsync seems to frequently be the preferred tool (and in general purpose applications is my usual default choice), but there are probably many people who blindly use rsync without thinking it through.

If you are running IIS on your PC you can add the directory that you are trying to reach as a Virtual Directory. To do this you right-click on your Site in ISS and press "Add Virtual Directory". Name the virtual folder. Point the virtual folder to your folder location on your local PC. You also have to supply credentials that has privileges to access the specific folder eg. HOSTNAME\username and password. After that you can access the file in the virtual folder as any other file on your site.

To get a connection from a data source, the following code should work:

import java.sql.Connection;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;

Context ctx = new InitialContext();
DataSource dataSource = ctx.lookup("java:comp/env/jdbc/xxxx");
Connection conn = dataSource.getConnection();

// use the connection

conn.close();

While you can look up a data source as defined in the Websphere Data Sources config (i.e. through the websphere console) directly, the lookup from java:comp/env/jdbc/xxxx means that there needs to be an entry in web.xml:

<resource-ref>
    <res-ref-name>jdbc/xxxx</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

This means that data sources can be mapped on a per application bases and you don't need to change the name of the data source if you want to point your app to a different data source. This is useful when deploying the application to different servers (e.g. test, preprod, prod) which need to point to different databases.

This was asked a long time ago but this may still help someone:

MongoDB profiler logs all the queries in the capped collection system.profile. See this: database profiler

1. Start mongod instance with --profile=2 option that enables logging all queries OR if mongod instances is already running, from mongoshell, run db.setProfilingLevel(2) after selecting database. (it can be verified by db.getProfilingLevel(), which should return 2)
2. After this, I have created a script which utilises mongodb's tailable cursor to tail this system.profile collection and write the entries in a file. To view the logs I just need to tail it:tail -f ../logs/mongologs.txt. This script can be started in background and it will log all the operation on the db in the file.

My code for tailable cursor for the system.profile collection is in nodejs; it logs all the operations along with queries happening in every collection of MyDb:

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
const fs = require('fs');
const file = '../logs/mongologs'
// Connection URL
const url = 'mongodb://localhost:27017';

// Database Name
const dbName = 'MyDb';
//Mongodb connection

MongoClient.connect(url, function (err, client) {
   assert.equal(null, err);
   const db = client.db(dbName);
   listen(db, {})
});

function listen(db, conditions) {
var filter = { ns: { $ne: 'MyDb.system.profile' } }; //filter for query
//e.g. if we need to log only insert queries, use {op:'insert'}
//e.g. if we need to log operation on only 'MyCollection' collection, use {ns: 'MyDb.MyCollection'}
//we can give a lot of filters, print and check the 'document' variable below

// set MongoDB cursor options
var cursorOptions = {
    tailable: true,
    awaitdata: true,
    numberOfRetries: -1
};

// create stream and listen
var stream = db.collection('system.profile').find(filter, cursorOptions).stream();

// call the callback
stream.on('data', function (document) {
    //this will run on every operation/query done on our database
    //print 'document' to check the keys based on which we can filter
    //delete data which we dont need in our log file

    delete document.execStats;
    delete document.keysExamined;
    //-----
    //-----

    //append the log generated in our log file which can be tailed from command line
    fs.appendFile(file, JSON.stringify(document) + '\n', function (err) {
        if (err) (console.log('err'))
    })

});

}

For tailable cursor in python using pymongo, refer the following code which filters for MyCollection and only insert operation:

import pymongo
import time
client = pymongo.MongoClient()
oplog = client.MyDb.system.profile
first = oplog.find().sort('$natural', pymongo.ASCENDING).limit(-1).next()

ts = first['ts']
while True:
    cursor = oplog.find({'ts': {'$gt': ts}, 'ns': 'MyDb.MyCollection', 'op': 'insert'},
                        cursor_type=pymongo.CursorType.TAILABLE_AWAIT)
    while cursor.alive:
        for doc in cursor:
            ts = doc['ts']
            print(doc)
            print('\n')
        time.sleep(1)

Note: Tailable cursor only works with capped collections. It cannot be used to log operations on a collection directly, instead use filter: 'ns': 'MyDb.MyCollection'

Note: I understand that the above nodejs and python code may not be of much help for some. I have just provided the codes for reference.

Use this link to find documentation for tailable cursor in your languarge/driver choice Mongodb Drivers

Another feature that i have added after this logrotate.

To make it more interesting and to hopefully enable less hair pulling for someone else. Using python, built dictionary for a device which we can use curl to configure.

Problem: {"timezone":"+5"} //throws an error " 5"

Solution: {"timezone":"%2B"+"5"} //Works

So, in a nutshell:

json = JSONEncoder().encode(var)
subprocess.call(["curl",ipaddress,"-XPUT","-d","data="+json])

The finalizer is for implicit cleanup - you should use this whenever a class manages resources that absolutely must be cleaned up as otherwise you would leak handles / memory etc...

Correctly implementing a finalizer is notoriously difficult and should be avoided wherever possible - the SafeHandle class (avaialble in .Net v2.0 and above) now means that you very rarely (if ever) need to implement a finalizer any more.

The IDisposable interface is for explicit cleanup and is much more commonly used - you should use this to allow users to explicitly release or cleanup resources whenever they have finished using an object.

Note that if you have a finalizer then you should also implement the IDisposable interface to allow users to explicitly release those resources sooner than they would be if the object was garbage collected.

See DG Update: Dispose, Finalization, and Resource Management for what I consider to be the best and most complete set of recommendations on finalizers and IDisposable.

First, JavaScript's switch is no faster than if/else (and sometimes much slower).

Second, the only way to use switch with multiple variables is to combine them into one primitive (string, number, etc) value:

var stateA = "foo";
var stateB = "bar";
switch (stateA + "-" + stateB) {
    case "foo-bar": ...
    ...
}

But, personally, I would rather see a set of if/else statements.

Edit: When all the values are integers, it appears that switch can out-perform if/else in Chrome. See the comments.

When should we use one over the other?

The decision is a trade-off between compatibility and API access.

Use a .NET Standard library when you want to increase the number of applications that will be compatible with your library, and you are okay with a decrease in the .NET API surface area your library can access.

Use a .NET Core library when you want to increase the .NET API surface area your library can access, and you are okay with allowing only .NET Core applications to be compatible with your library.

For example, a library that targets .NET Standard 1.3 will be compatible with applications that target .NET Framework 4.6, .NET Core 1.0, Universal Windows Platform 10.0, and any other platform that supports .NET Standard 1.3. The library will not have access to some parts of the .NET API, though. For instance, the Microsoft.NETCore.CoreCLR package is compatible with .NET Core, but not with .NET Standard.

What is the difference between Class Library (.NET Standard) and Class Library (.NET Core)?

Compatibility: Libraries that target .NET Standard will run on any .NET Standard compliant runtime, such as .NET Core, .NET Framework, Mono/Xamarin. On the other hand, libraries that target .NET Core can only run on the .NET Core runtime.

API Surface Area: .NET Standard libraries come with everything in NETStandard.Library, whereas .NET Core libraries come with everything in Microsoft.NETCore.App. The latter includes approximately 20 additional libraries, some of which we can add manually to our .NET Standard library (such as System.Threading.Thread) and some of which are not compatible with the .NET Standard (such as Microsoft.NETCore.CoreCLR).

Also, .NET Core libraries specify a runtime and come with an application model. That's important, for instance, to make unit test class libraries runnable.

Why do both exist?

Ignoring libraries for a moment, the reason that .NET Standard exists is for portability; it defines a set of APIs that .NET platforms agree to implement. Any platform that implements a .NET Standard is compatible with libraries that target that .NET Standard. One of those compatible platforms is .NET Core.

Coming back to libraries, the .NET Standard library templates exist to run on multiple runtimes (at the expense of API surface area). Conversely, the .NET Core library templates exist to access more API surface area (at the expense of compatibility) and to specify a platform against which to build an executable.

Here is an interactive matrix that shows which .NET Standard supports which .NET implementation(s) and how much API surface area is available.

The counter variable inside the loop is called loop.index in jinja2.

>>> from jinja2 import Template

>>> s = "{% for element in elements %}{{loop.index}} {% endfor %}"
>>> Template(s).render(elements=["a", "b", "c", "d"])

Explicit pass-through

Similar to nesting the callbacks, this technique relies on closures. Yet, the chain stays flat - instead of passing only the latest result, some state object is passed for every step. These state objects accumulate the results of the previous actions, handing down all values that will be needed later again plus the result of the current task.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(b => [resultA, b]); // function(b) { return [resultA, b] }
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

Here, that little arrow b => [resultA, b] is the function that closes over resultA, and passes an array of both results to the next step. Which uses parameter destructuring syntax to break it up in single variables again.

Before destructuring became available with ES6, a nifty helper method called .spread() was pro­vi­ded by many promise libraries (Q, Bluebird, when, …). It takes a function with multiple parameters - one for each array element - to be used as .spread(function(resultA, resultB) { ….

Of course, that closure needed here can be further simplified by some helper functions, e.g.

function addTo(x) {
    // imagine complex `arguments` fiddling or anything that helps usability
    // but you get the idea with this simple one:
    return res => [x, res];
}

…
return promiseB(…).then(addTo(resultA));

Alternatively, you can employ Promise.all to produce the promise for the array:

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return Promise.all([resultA, promiseB(…)]); // resultA will implicitly be wrapped
                                                    // as if passed to Promise.resolve()
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

And you might not only use arrays, but arbitrarily complex objects. For example, with _.extend or Object.assign in a different helper function:

function augment(obj, name) {
    return function (res) { var r = Object.assign({}, obj); r[name] = res; return r; };
}

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(augment({resultA}, "resultB"));
    }).then(function(obj) {
        // more processing
        return // something using both obj.resultA and obj.resultB
    });
}

While this pattern guarantees a flat chain and explicit state objects can improve clarity, it will become tedious for a long chain. Especially when you need the state only sporadically, you still have to pass it through every step. With this fixed interface, the single callbacks in the chain are rather tightly coupled and inflexible to change. It makes factoring out single steps harder, and callbacks cannot be supplied directly from other modules - they always need to be wrapped in boilerplate code that cares about the state. Abstract helper functions like the above can ease the pain a bit, but it will always be present.

Jan 2019: Jest version 23.6

For anyone looking into this question recently especially if testing using npm or yarn directly

Currently, you don't have to change the configuration options

As per Jest official website, you can do the following to generate coverage reports:

1- For npm:

You must put -- before passing the --coverage argument of Jest

npm test -- --coverage

if you try invoking the --coverage directly without the -- it won't work

2- For yarn:

You can pass the --coverage argument of jest directly

yarn test --coverage

To answer your updated question you can do

String[] lines = ("Name =              Bob\n" +
        "Age =               27\n" +
        "Occupation =        Student\n" +
        "Status =            Single").split("\n");

for (String line : lines) {
    String[] parts = line.split(" = +");
    System.out.printf("%-19s %s%n", parts[0] + " =", parts[1]);
}

prints

Name =              Bob
Age =               27
Occupation =        Student
Status =            Single

If you are using gradle you can just add this to your build.gradle

springBoot {
    executable = true
}

You can then run your application by typing ./your-app.jar

Also, you can find a complete guide here to set up your app as a service

That 2GB limit you see is the total memory of the VM in which docker runs.

If you are using docker-for-windows or docker-for-mac you can easily increase it from the Whale icon in the task bar, then go to Preferences -> Advanced:

But if you are using VirtualBox behind, open VirtualBox, Select and configure the docker-machine assigned memory.

See this for Mac:

https://docs.docker.com/docker-for-mac/#memory

MEMORY By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. You can increase the RAM on the app to get faster performance by setting this number higher (for example to 3) or lower (to 1) if you want Docker for Mac to use less memory.

For Windows:

If you are just looping through 10k rows in column A, then dump the row into a variant array and then loop through that.

You can then either add the elements to a new array (while adding rows when needed) and using Transpose() to put the array onto your range in one move, or you can use your iterator variable to track which row you are on and add rows that way.

Dim i As Long
Dim varray As Variant

varray = Range("A2:A" & Cells(Rows.Count, "A").End(xlUp).Row).Value

For i = 1 To UBound(varray, 1)
    ' do stuff to varray(i, 1)
Next

Here is an example of how you could add rows after evaluating each cell. This example just inserts a row after every row that has the word "foo" in column A. Not that the "+2" is added to the variable i during the insert since we are starting on A2. It would be +1 if we were starting our array with A1.

Sub test()

Dim varray As Variant
Dim i As Long

varray = Range("A2:A10").Value

'must step back or it'll be infinite loop
For i = UBound(varray, 1) To LBound(varray, 1) Step -1
    'do your logic and evaluation here
    If varray(i, 1) = "foo" Then
       'not how to offset the i variable 
       Range("A" & i + 2).EntireRow.Insert
    End If
Next

End Sub

I use this custom binding (based on this fiddle by RP Niemeyer, see his answer to this question), which makes sure the numeric value is properly converted from string to number (as suggested by the solution of Michael Best):

Javascript:

ko.bindingHandlers.valueAsNumber = {
    init: function (element, valueAccessor, allBindingsAccessor) {
        var observable = valueAccessor(),
            interceptor = ko.computed({
                read: function () {
                    var val = ko.utils.unwrapObservable(observable);
                    return (observable() ? observable().toString() : observable());
                },
                write: function (newValue) {
                    observable(newValue ? parseInt(newValue, 10) : newValue);
                },
                owner: this
            });
        ko.applyBindingsToNode(element, { value: interceptor });
    }
};

Example HTML:

<select data-bind="valueAsNumber: level, event:{ change: $parent.permissionChanged }">
    <option value="0"></option>
    <option value="1">R</option>
    <option value="2">RW</option>
</select>

When the preprocessor sees #if it checks whether the next token has a non-zero value. If it does, it keeps the code around for the compiler. If it doesn't, it gets rid of that code so the compiler never sees it.

If someone says #if 0 they are effectively commenting out the code so it will never be compiled. You can think of this the same as if they had put /* ... */ around it. It's not quite the same, but it has the same effect.

If you want to understand what happened in detail, you can often look. Many compilers will allow you to see the files after the preprocessor has run. For example, on Visual C++ the switch /P command will execute the preprocessor and put the results in a .i file.

In android studio add/change this line at the end of gradle.properties (Global Properties):

...
org.gradle.jvmargs=-XX\:MaxHeapSize\=1024m -Xmx1024m 

if it doesn't work you can retry with bigger than 1024 heap size.

An old question, but I'll answer anyway. The answer to the actual question asked is that the bare return is redundant and should be left out.

Furthermore, the suggested value is false for the following reason:

if (ret<0) return;

Redefining a C reserved word as a macro is a bad idea on the face of it, but this particular suggestion is simply unsupportable, both as an argument and as code.

1st method

MyTable.objects.filter(pk=some_value).update(field1='some value')

2nd Method

q = MyModel.objects.get(pk=some_value)
q.field1 = 'some value'
q.save()

3rd method

By using get_object_or_404

q = get_object_or_404(MyModel,pk=some_value)
q.field1 = 'some value'
q.save()

4th Method

if you required if pk=some_value exist then update it other wise create new one by using update_or_create.

MyModel.objects.update_or_create(pk=some_value,defaults={'field1':'some value'})

A little more generic solution (you can specify the number of parts you want, not just split 'in half'):

EDIT: updated post to handle odd list lengths

EDIT2: update post again based on Brians informative comments

def split_list(alist, wanted_parts=1):
    length = len(alist)
    return [ alist[i*length // wanted_parts: (i+1)*length // wanted_parts] 
             for i in range(wanted_parts) ]

A = [0,1,2,3,4,5,6,7,8,9]

print split_list(A, wanted_parts=1)
print split_list(A, wanted_parts=2)
print split_list(A, wanted_parts=8)

Using flexbox

   #parent_div_1{
     display:flex;
     flex-wrap: wrap;
  }

You could use this plugin which creates a form, and submits it, then removes it from the page.

jQuery.download = function(url, data, method) {
    //url and data options required
    if (url && data) {
        //data can be string of parameters or array/object
        data = typeof data == 'string' ? data : jQuery.param(data);
        //split params into form inputs
        var inputs = '';
        jQuery.each(data.split('&'), function() {
            var pair = this.split('=');
            inputs += '<input type="hidden" name="' + pair[0] +
                '" value="' + pair[1] + '" />';
        });
        //send request
        jQuery('<form action="' + url +
                '" method="' + (method || 'post') + '">' + inputs + '</form>')
            .appendTo('body').submit().remove();
    };
};


$.download(
    '/export.php',
    'filename=mySpreadsheet&format=xls&content=' + spreadsheetData
);

This worked for me. Found this plugin here

I've found a simple javascript/jquery solution which utilizes the bootstrap modal events.

My solution also fixes the position:fixed problem where it scrolls the background page all the way back to the top instead of staying in place when modal window is opened/closed.

See details here

Does allowing people to say

myTeam.subList(3, 5);

make any sense at all? If not then it shouldn't be a List.

I find hardcoding(sic) "" every time for checking an empty string not as good.

Clean code approach

Doing this: foo == "" is very bad practice. "" is a magical value. You should never check against magical values (more commonly known as magical numbers)

What you should do is compare to a descriptive variable name.

Descriptive variable names

One may think that "empty_string" is a descriptive variable name. It isn't.

Before you go and do empty_string = "" and think you have a great variable name to compare to. This is not what "descriptive variable name" means.

A good descriptive variable name is based on its context. You have to think about what the empty string is.

• Where does it come from.
• Why is it there.
• Why do you need to check for it.

Simple form field example

You are building a form where a user can enter values. You want to check if the user wrote something or not.

A good variable name may be not_filled_in

This makes the code very readable

if formfields.name == not_filled_in:
    raise ValueError("We need your name")

Thorough CSV parsing example

You are parsing CSV files and want the empty string to be parsed as None

(Since CSV is entirely text based, it cannot represent None without using predefined keywords)

A good variable name may be CSV_NONE

This makes the code easy to change and adapt if you have a new CSV file that represents None with another string than ""

if csvfield == CSV_NONE:
    csvfield = None

There are no questions about if this piece of code is correct. It is pretty clear that it does what it should do.

Compare this to

if csvfield == EMPTY_STRING:
    csvfield = None

The first question here is, Why does the empty string deserve special treatment?

This would tell future coders that an empty string should always be considered as None.

This is because it mixes business logic (What CSV value should be None) with code implementation (What are we actually comparing to)

There needs to be a separation of concern between the two.

Just to add that you don't really need to create new IDs, something like the following will work.

In the layout:

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@android:id/list"/>

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@android:id/empty"
    android:text="Empty"/>

Then in the activity:

    ListView listView = (ListView) findViewById(android.R.id.list);
    listView.setEmptyView(findViewById(android.R.id.empty));

For C/C++ programs there's very good package gpp-compiler.

Shortcuts:

• To compile and run: F5
• To debug: F6

Try using printf function or the concatination operator

Here's a Swift 3 adaptation of @leviatan's answer :

EXTENSION

import UIKit


extension UIScrollView {

    func resizeScrollViewContentSize() {

        var contentRect = CGRect.zero

        for view in self.subviews {

            contentRect = contentRect.union(view.frame)

        }

        self.contentSize = contentRect.size

    }

}

USAGE

scrollView.resizeScrollViewContentSize()

Very easy to use !

I guess there is a simple solution which I recently used after going through so many answers here.

with open(file_name) as f_in:   
    for line in f_in:
        if len(line.split()) == 0:
            continue

This just does the same work, ignoring all empty line.

I think this uses more native capabilities

Enjoy!

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

I had the same issue.

Make sure that In SQL Server configuration --> SQL Server Services --> SQL Server Agent is enable

This solved my problem

Method 1

The problem with your code is that you are selecting the .remode_hover that is a descendant of .remode_selected. So the first part of getting your code to work correctly is by removing that space

.reMode_selected.reMode_hover:hover

Then, in order to get the style to not work, you have to override the style set by the :hover. In other words, you need to counter the background-color property. So the final code will be

.reMode_selected.reMode_hover:hover {
  background-color:inherit;
}
.reMode_hover:hover {
  background-color: #f0ac00;
}

Fiddle

Method 2

An alternative method would be to use :not(), as stated by others. This will return any element that doesn't have the class or property stated inside the parenthesis. In this case, you would put .remode_selected in there. This will target all elements that don't have a class of .remode_selected

Fiddle

However, I would not recommend this method, because of the fact that it was introduced in CSS3, so browser support is not ideal.

Method 3

A third method would be to use jQuery. You can target the .not() selector, which would be similar to using :not() in CSS, but with much better browser support

Fiddle

I use this

import android.app.Activity;
import android.support.annotation.StringRes;
import android.widget.Toast;

public class ExitApp {

    private static long lastClickTime;

    public static void now(Activity ctx, @StringRes int message) {
        now(ctx, ctx.getString(message), 2500);
    }

    public static void now(Activity ctx, @StringRes int message, long time) {
        now(ctx, ctx.getString(message), time);
    }

    public static void now(Activity ctx, String message, long time) {
        if (ctx != null && !message.isEmpty() && time != 0) {
            if (lastClickTime + time > System.currentTimeMillis()) {
                ctx.finish();
            } else {
                Toast.makeText(ctx, message, Toast.LENGTH_SHORT).show();
                lastClickTime = System.currentTimeMillis();
            }
        }
    }

}

use to in event onBackPressed

@Override
public void onBackPressed() {
   ExitApp.now(this,"Press again for close");
}

or ExitApp.now(this,R.string.double_back_pressed)

for change seconds need for close, specified miliseconds

ExitApp.now(this,R.string.double_back_pressed,5000)

setTimout executes outside of angular. You need to use $timeout service for this to work:

var app = angular.module('test', []);

    app.controller('TestCtrl', function ($scope, $timeout) {
       $scope.testValue = 0;

        $timeout(function() {
            console.log($scope.testValue++);
        }, 500);
    });

The reason is that two-way binding in angular uses dirty checking. This is a good article to read about angular's dirty checking. $scope.$apply() kicks off a $digest cycle. This will apply the binding. $timeout handles the $apply for you so it is the recommended service to use when using timeouts.

Essentially, binding happens during the $digest cycle (if the value is seen to be different).

You need to grant the user or group rights to use the profile. They need to be added to the msdb database and then you will see them available in the mail wizard when you are maintaining security for mail.

Read up the security here: http://msdn.microsoft.com/en-us/library/ms175887.aspx

See a listing of mail procedures here: http://msdn.microsoft.com/en-us/library/ms177580.aspx

Example script for 'TestUser' to use the profile named 'General Admin Mail'.

USE [msdb]
GO
CREATE USER [TestUser] FOR LOGIN [testuser]
GO
USE [msdb]
GO
EXEC sp_addrolemember N'DatabaseMailUserRole', N'TestUser'
GO

EXECUTE msdb.dbo.sysmail_add_principalprofile_sp
    @profile_name = 'General Admin Mail',
    @principal_name = 'TestUser',
    @is_default = 1 ;

An alternative to extend LayoutManager can be just set the size of the view manually.

Number of items per row height (if all the items have the same height and the separator is included on the row)

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) mListView.getLayoutParams();
params.height = mAdapter.getItemCount() * getResources().getDimensionPixelSize(R.dimen.row_height);
mListView.setLayoutParams(params);

Is still a workaround, but for basic cases it works.

The MySQL dependency should be like the following syntax in the pom.xml file.

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.21</version>
    </dependency>

Make sure the syntax, groupId, artifactId, Version has included in the dependancy.

To open the Eye Dropper simply:

Now with Android Studio and Gradle, you can have multiple resource folders in your project. Allowing to organize not only your layout files but any kind of resources.

It's not exactly a sub-folder, but may separte parts of your application.

The configuration is like this:

    main {
        res.srcDirs = ['src/main/res', 'src/main/res2']
    }
}

Check the documentation.

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

What is embedded bitcode?

According to docs:

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

Update: This phrase in "New Features in Xcode 7" made me to think for a long time that Bitcode is needed for Slicing to reduce app size:

When you archive for submission to the App Store, Xcode will compile your app into an intermediate representation. The App Store will then compile the bitcode down into the 64 or 32 bit executables as necessary.

However that's not true, Bitcode and Slicing work independently: Slicing is about reducing app size and generating app bundle variants, and Bitcode is about certain binary optimizations. I've verified this by checking included architectures in executables of non-bitcode apps and founding that they only include necessary ones.

Bitcode allows other App Thinning component called Slicing to generate app bundle variants with particular executables for particular architectures, e.g. iPhone 5S variant will include only arm64 executable, iPad Mini armv7 and so on.

When to enable ENABLE_BITCODE in new Xcode?

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

What happens to the binary when ENABLE_BITCODE is enabled in the new Xcode?

From Xcode 7 reference:

Activating this setting indicates that the target or project should generate bitcode during compilation for platforms and architectures which support it. For Archive builds, bitcode will be generated in the linked binary for submission to the app store. For other builds, the compiler and linker will check whether the code complies with the requirements for bitcode generation, but will not generate actual bitcode.

Here's a couple of links that will help in deeper understanding of Bitcode:

• Bitcode Demystified
• Why I'm not enabling Bitcode

This is what worked for me to change the color to white.

Another way to achieve this is to use the Natural Language Tool Kit (nltk).

import nltk
data= "Hey, you - what are you doing here!?"
word_tokens = nltk.tokenize.regexp_tokenize(data, r'\w+')
print word_tokens

This prints: ['Hey', 'you', 'what', 'are', 'you', 'doing', 'here']

The biggest drawback of this method is that you need to install the nltk package.

The benefits are that you can do a lot of fun stuff with the rest of the nltk package once you get your tokens.

Please note, I wrote this answer based on Python 3.x. No worries you can assign print() statement to the variable like this.

>>> var = print('some text')
some text
>>> var
>>> type(var)
<class 'NoneType'>

According to the documentation,

All non-keyword arguments are converted to strings like str() does and written to the stream, separated by sep and followed by end. Both sep and end must be strings; they can also be None, which means to use the default values. If no objects are given, print() will just write end.

The file argument must be an object with a write(string) method; if it is not present or None, sys.stdout will be used. Since printed arguments are converted to text strings, print() cannot be used with binary mode file objects. For these, use file.write(...) instead.

That's why we cannot assign print() statement values to the variable. In this question you have ask (or any function). So print() also a function with the return value with None. So the return value of python function is None. But you can call the function(with parenthesis ()) and save the return value in this way.

>>> var = some_function()

So the var variable has the return value of some_function() or the default value None. According to the documentation about print(), All non-keyword arguments are converted to strings like str() does and written to the stream. Lets look what happen inside the str().

Return a string version of object. If object is not provided, returns the empty string. Otherwise, the behavior of str() depends on whether encoding or errors is given, as follows.

So we get a string object, then you can modify the below code line as follows,

>>> var = str(some_function())

or you can use str.join() if you really have a string object.

Return a string which is the concatenation of the strings in iterable. A TypeError will be raised if there are any non-string values in iterable, including bytes objects. The separator between elements is the string providing this method.

change can be as follows,

>>> var = ''.join(some_function())  # you can use this if some_function() really returns a string value

you can use UPDATE command.

UPDATE table_name SET name=@name, email=@email, phone=@phone WHERE client_id=@client_id

Add a shortcut:

$.Shortcuts.add({
    type: 'down',
    mask: 'Ctrl+A',
    handler: function() {
        debug('Ctrl+A');
    }
});

Start reacting to shortcuts:

$.Shortcuts.start();

Add a shortcut to “another” list:

$.Shortcuts.add({
    type: 'hold',
    mask: 'Shift+Up',
    handler: function() {
        debug('Shift+Up');
    },
    list: 'another'
});

Activate “another” list:

$.Shortcuts.start('another');
Remove a shortcut:
$.Shortcuts.remove({
    type: 'hold',
    mask: 'Shift+Up',
    list: 'another'
});

Stop (unbind event handlers):

$.Shortcuts.stop();

If you use Lodash.

var n = 1;_x000D_
_x000D_
alert( _.padLeft(n, 2, 0) ); // 01_x000D_
_x000D_
n = 10;_x000D_
_x000D_
alert( _.padLeft(n, 2, 0) ); // 10

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/3.10.0/lodash.min.js"></script>

your code

SELECT * FROM Cases WHERE created_at BETWEEN '2013-05-01' AND '2013-05-01'

how SQL reading it

SELECT * FROM Cases WHERE '2013-05-01 22:25:19' BETWEEN '2013-05-01 00:00:00' AND '2013-05-01 00:00:00'

if you don't mention time while comparing DateTime and Date by default hours:minutes:seconds will be zero in your case dates are the same but if you compare time created_at is 22 hours ahead from your end date range

if the above is clear you fix this in many ways like putting ending hours in your end date eg BETWEEN '2013-05-01' AND ''2013-05-01 23:59:59''

OR

simply cast create_at as date like cast(created_at as date) after casting as date '2013-05-01 22:25:19' will be equal to '2013-05-01 00:00:00'

Use Map<Integer, List<String>>:

Map<Integer, List<String>> map = new LinkedHashMap< Integer, List<String>>();

map.put(-1505711364, new ArrayList<>(Arrays.asList("4")));
map.put(294357273, new ArrayList<>(Arrays.asList("15", "71")));
//...

To add a new key/value pair in this map:

public void add(Integer key, String newValue) {
    List<String> currentValue = map.get(key);
    if (currentValue == null) {
        currentValue = new ArrayList<String>();
        map.put(key, currentValue);
    }
    currentValue.add(newValue);
}

Instead of RenderViewToString I prefer a approach like

return Json(new { Url = Url.Action("Evil", model) });

then you can catch the result in your javascript and do something like

success: function(data) {
    $.post(data.Url, function(partial) { 
        $('#IdOfDivToUpdate').html(partial);
    });
}

You can use this code to check whether the input string contains any spaces?

public static void main(String[]args)
{
    Scanner sc=new Scanner(System.in);
    System.out.println("enter the string...");
    String s1=sc.nextLine();
    int l=s1.length();
    int count=0;
    for(int i=0;i<l;i++)
    {
        char c=s1.charAt(i);
        if(c==' ')
        {
        System.out.println("spaces are in the position of "+i);
        System.out.println(count++);
        }
        else
        {
        System.out.println("no spaces are there");
    }
}

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

All the below answers would return you the list.Your need to convert it to matrix

def MATMUL(X, Y):
    rows_A = len(X)
    cols_A = len(X[0])
    rows_B = len(Y)
    cols_B = len(Y[0])

    if cols_A != rows_B:
        print "Matrices are not compatible to Multiply. Check condition C1==R2"
        return

    # Create the result matrix
    # Dimensions would be rows_A x cols_B
    C = [[0 for row in range(cols_B)] for col in range(rows_A)]
    print C

    for i in range(rows_A):
        for j in range(cols_B):
            for k in range(cols_A):
                C[i][j] += A[i][k] * B[k][j]

    C = numpy.matrix(C).reshape(len(A),len(B[0]))

    return C

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

no you do not .. it will create it when you add the success value to the object.the default class is inherited if you do not specify one.

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

Similar to older answers, but a bit simpler, without the lambda:

filter_kwargs = {
    'field_a': 123,
    'field_b__in': (3, 4, 5, ),
}

To filter these two conditions using OR:

Item.objects.filter(Q(field_a=123) | Q(field_b__in=(3, 4, 5, ))

To get the same result programmatically:

list_of_Q = [Q(**{key: val}) for key, val in filter_kwargs.items()]
Item.objects.filter(reduce(operator.or_, list_of_Q))

(broken in two lines here, for clarity)

operator is in standard library: import operator
From docstring:

or_(a, b) -- Same as a | b.

For Python3, reduce is not a builtin any more but is still in the standard library: from functools import reduce

P.S.

Don't forget to make sure list_of_Q is not empty - reduce() will choke on empty list, it needs at least one element.

The only way to reliably detect if a socket is still connected is to periodically try to send data. Its usually more convenient to define an application level 'ping' packet that the clients ignore, but if the protocol is already specced out without such a capability you should be able to configure tcp sockets to do this by setting the SO_KEEPALIVE socket option. I've linked to the winsock documentation, but the same functionality should be available on all BSD-like socket stacks.

I usually sort the data by the field I need to do the distinct count of then use IF(A2=A1,0,1); you get then get a 1 in the top row of each group of IDs. Simple and doesn't take any time to calculate on large datasets.

Here you go:

public static void main(String[] args) throws ParseException {

        SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");

        String oeStartDateStr = "04/01/";
        String oeEndDateStr = "11/14/";

        Calendar cal = Calendar.getInstance();
        Integer year = cal.get(Calendar.YEAR);

        oeStartDateStr = oeStartDateStr.concat(year.toString());
        oeEndDateStr = oeEndDateStr.concat(year.toString());

        Date startDate = sdf.parse(oeStartDateStr);
        Date endDate = sdf.parse(oeEndDateStr);
        Date d = new Date();
        String currDt = sdf.format(d);


        if((d.after(startDate) && (d.before(endDate))) || (currDt.equals(sdf.format(startDate)) ||currDt.equals(sdf.format(endDate)))){
            System.out.println("Date is between 1st april to 14th nov...");
        }
        else{
            System.out.println("Date is not between 1st april to 14th nov...");
        }
    }

When you have classes or methods which don't fit cleanly into the Object-Oriented Paradigm, which do dangerous stuff, which need to be called from other classes and methods under your control, and which you don't want to let anyone else use.

public class DangerousClass {
    public void SafeMethod() { }
    internal void UpdateGlobalStateInSomeBizarreWay() { }
}

Try this code:

String str = "a12.334tyz.78x";
str = str.replaceAll("[^\\d.]", "");

Now str will contain "12.334.78".

This is another way to do it, very similar to Manoj Govindan's answer above:

import re
regex_http_          = re.compile(r'^HTTP_.+$')
regex_content_type   = re.compile(r'^CONTENT_TYPE$')
regex_content_length = re.compile(r'^CONTENT_LENGTH$')

request_headers = {}
for header in request.META:
    if regex_http_.match(header) or regex_content_type.match(header) or regex_content_length.match(header):
        request_headers[header] = request.META[header]

That will also grab the CONTENT_TYPE and CONTENT_LENGTH request headers, along with the HTTP_ ones. request_headers['some_key] == request.META['some_key'].

Modify accordingly if you need to include/omit certain headers. Django lists a bunch, but not all, of them here: https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.META

Django's algorithm for request headers:

1. Replace hyphen - with underscore _
2. Convert to UPPERCASE.
3. Prepend HTTP_ to all headers in original request, except for CONTENT_TYPE and CONTENT_LENGTH.

The values of each header should be unmodified.

Unfortunately, MySQL doesn't support DEFAULT parameter values, so:

CREATE PROCEDURE `blah`
(
  myDefaultParam int DEFAULT 0
)
BEGIN
  -- Do something here
END

returns the error:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to use 
near 'DEFAULT 0) BEGIN END' at line 3

To work around this limitation, simply create additional procedures that assign default values to the original procedure:

DELIMITER //

DROP PROCEDURE IF EXISTS blah//
DROP PROCEDURE IF EXISTS blah2//
DROP PROCEDURE IF EXISTS blah1//
DROP PROCEDURE IF EXISTS blah0//

CREATE PROCEDURE blah(param1 INT UNSIGNED, param2 INT UNSIGNED)
BEGIN
    SELECT param1, param2;
END;
//

CREATE PROCEDURE blah2(param1 INT UNSIGNED, param2 INT UNSIGNED)
BEGIN
    CALL blah(param1, param2);
END;
//

CREATE PROCEDURE blah1(param1 INT UNSIGNED)
BEGIN
    CALL blah2(param1, 3);
END;
//

CREATE PROCEDURE blah0()
BEGIN
    CALL blah1(4);
END;
//

Then, running this:

CALL blah(1, 1);
CALL blah2(2, 2);
CALL blah1(3);
CALL blah0();

will return:

+--------+--------+
| param1 | param2 |
+--------+--------+
|      1 |      1 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      2 |      2 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      3 |      3 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      4 |      3 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Then, if you make sure to only use the blah2(), blah1() and blah0() procedures, your code will not need to be immediately updated, when you add a third parameter to the blah() procedure.

As others have said, there are patterns specific to functional programming. I think the issue of getting rid of design patterns is not so much a matter of switching to functional, but a matter of language features.

Take a look at how Scala does away with the "singleton pattern": you simply declare an object instead of a class. Another feature, pattern matching, helps avoiding the clunkiness of the visitor pattern. See the comparison here: Scala's Pattern Matching = Visitor Pattern on Steroids

And Scala, like F#, is a fusion of OO-functional. I don't know about F#, but it probably has these kind of features.

Closures are present in functional language, but they need not be restricted to them. They help with the delegator pattern.

One more observation. This piece of code implements a pattern: it's such a classic and it's so elemental that we don't usually think of it as a "pattern", but it sure is:

for(int i = 0; i < myList.size(); i++) { doWhatever(myList.get(i)); }

Imperative languages like Java and C# have adopted what is essentially a functional construct to deal with this: "foreach".

If you are on a unixoid operating system and want to extract just a single file you can try the following. The structure of the chrome://cache pages is URL, parsed HTTP header, hex dump of the HTTP header and then hex dump of the payload.

To extract a file copy all payload lines from a Chrome cache page to the clipboard (starting at the second 00000000: ... line), paste them into a text editor and save them as a plain text file (e.g. file.txt). If the payload is a gzipped WOFF file use xxd -r file.txt > file.woff.gz to convert it back to a binary file and gunzip file.woff.gz for decompression.

You can then use woff2otf to convert WOFF files to the OTF format or woff2 to convert WOFF 2.0 files to the TTF format. For batch processing this workflow should obviously be scripted.

javac is the Java compiler. java is the JVM and what you use to execute a Java program. You do not execute .java files, they are just source files. Presumably there is .jar somewhere (or a directory containing .class files) that is the product of building it in Eclipse:

java/src/com/mypackage/Main.java
java/classes/com/mypackage/Main.class
java/lib/mypackage.jar

From directory java execute:

java -cp lib/mypackage.jar Main arg1 arg2

You can also set your div with the following:

#something {width: 400px; margin: auto;}

With that setting, the div will have a set width, and the margin and either side will automatically set depending on the with of the browser.

Go File -> New Project.

Select Web under Visual C#.

Select ASP.NET Web Application

select mvc

when solution is created, you will find resources getting added in solution in status bar of vs 2013.

Check property of Dll file --> system.web.mvc, it shows latest version (5.2.2.0)

but depending on your OS runtime version will be decided.

Unfortunately it does not work in Chrome or Edge, but it does work in FireFox:

$(document)
// uncheck it when clicked
.on("click","input[type='radio']", function(){ $(this).prop("checked",false); })
// re-check it if value is changed to this input
.on("change","input[type='radio']", function(){ $(this).prop("checked",true); });

with this solution:

for(int i = dtPerson.Rows.Count-1; i >= 0; i--) 
{ 
    DataRow dr = dtPerson.Rows[i]; 
    if (dr["name"] == "Joe")
        dr.Delete();
} 

if you are going to use the datatable after deleting the row, you will get an error. So what you can do is: replace dr.Delete(); with dtPerson.Rows.Remove(dr);

You can do superscript with vertical-align: super, (plus an accompanying font-size reduction).

However, be sure to read the other answers here, particularly those by paulmurray and cletus, for useful information.

There are a number of different icons and even splash screens that you can set for various devices. This answer goes through how to support them all.

Total Overhead

If you take out the comments that's 3KB of extra HTML, if you don't support splash screens that's 1.5KB. If you are using GZIP compression on your HTML content, which everyone should be doing these days, that leaves you with about 634 Bytes of overhead per request to support all platforms or 446 Bytes without splash screens. I personally think its worth it to support IOS, Android and Windows devices but its your choice, I'm just giving the options!

Side Note About The Current Web Icon/Splash Screen/Settings Situation

This situation with vendor specific icons, splash screens and special tags to control the web browser or pinned icons is ridiculous. In a perfect world we would all use a favicon.svg file which could look good at any size and could be placed at the root of the page. Only FireFox supports this at the time of writing (See CanIUse.com).

However, icons are not the only setting these days, there are several other vendor specific settings (shown above) but a favicon.svg file would cover most use cases.

Update

Updated to include the new Android/Chrome version M39+ favicon/theming options. Interestingly, they have gone with a similar approach to Microsoft but are using a JSON file instead of XML.

I've developed the Function named "compareValue()" in Javascript. it returns whether the value is same or not. I've called compareValue() in for loop of one Object. you can get difference of two objects in diffParams.

var diffParams = {};_x000D_
var obj1 = {"a":"1", "b":"2", "c":[{"key":"3"}]},_x000D_
    obj2 = {"a":"1", "b":"66", "c":[{"key":"55"}]};_x000D_
_x000D_
for( var p in obj1 ){_x000D_
  if ( !compareValue(obj1[p], obj2[p]) ){_x000D_
    diffParams[p] = obj1[p];_x000D_
  }_x000D_
}_x000D_
_x000D_
function compareValue(val1, val2){_x000D_
  var isSame = true;_x000D_
  for ( var p in val1 ) {_x000D_
_x000D_
    if (typeof(val1[p]) === "object"){_x000D_
      var objectValue1 = val1[p],_x000D_
          objectValue2 = val2[p];_x000D_
      for( var value in objectValue1 ){_x000D_
        isSame = compareValue(objectValue1[value], objectValue2[value]);_x000D_
        if( isSame === false ){_x000D_
          return false;_x000D_

Using the excellent answer from Max and This post about adding extra data files like images or sound & my own research/testing, I've figured out what I believe is the easiest way to add such files.

If you would like to see a live example, my repository is here on GitHub.

Note: this is for compiling using the --onefile or -F command with pyinstaller.

My environment is as follows.

• Python 3.3.7
• Tkinter 8.6 (check version)
• Pyinstaller 3.6

Solving the problem in 2 steps

To solve the issue we need to specifically tell Pyinstaller that we have extra files that need to be "bundled" with the application.

We also need to be using a 'relative' path, so the application can run properly when it's running as a Python Script or a Frozen EXE.

With that being said we need a function that allows us to have relative paths. Using the function that Max Posted we can easily solve the relative pathing.

def img_resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

We would use the above function like this so the application icon shows up when the app is running as either a Script OR Frozen EXE.

icon_path = img_resource_path("app/img/app_icon.ico")
root.wm_iconbitmap(icon_path)

The next step is that we need to instruct Pyinstaller on where to find the extra files when it's compiling so that when the application is run, they get created in the temp directory.

We can solve this issue two ways as shown in the documentation, but I personally prefer managing my own .spec file so that's how we're going to do it.

First, you must already have a .spec file. In my case, I was able to create what I needed by running pyinstaller with extra args, you can find extra args here. Because of this, my spec file may look a little different than yours but I'm posting all of it for reference after I explain the important bits.

added_files is essentially a List containing Tuple's, in my case I'm only wanting to add a SINGLE image, but you can add multiple ico's, png's or jpg's using ('app/img/*.ico', 'app/img') You may also create another tuple like soadded_files = [ (), (), ()] to have multiple imports

The first part of the tuple defines what file or what type of file's you would like to add as well as where to find them. Think of this as CTRL+C

The second part of the tuple tells Pyinstaller, to make the path 'app/img/' and place the files in that directory RELATIVE to whatever temp directory gets created when you run the .exe. Think of this as CTRL+V

Under a = Analysis([main..., I've set datas=added_files, originally it used to be datas=[] but we want out the list of imports to be, well, imported so we pass in our custom imports.

You don't need to do this unless you want a specific icon for the EXE, at the bottom of the spec file I'm telling Pyinstaller to set my application icon for the exe with the option icon='app\\img\\app_icon.ico'.

added_files = [
    ('app/img/app_icon.ico','app/img/')
]
a = Analysis(['main.py'],
             pathex=['D:\\Github Repos\\Processes-Killer\\Process Killer'],
             binaries=[],
             datas=added_files,
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='Process Killer',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True , uac_admin=True, icon='app\\img\\app_icon.ico')

Compiling to EXE

I'm very lazy; I don't like typing things more than I have to. I've created a .bat file that I can just click. You don't have to do this, this code will run in a command prompt shell just fine without it.

Since the .spec file contains all of our compiling settings & args (aka options) we just have to give that .spec file to Pyinstaller.

pyinstaller.exe "Process Killer.spec"

Try to upgrade and install new packages

sudo apt-get update && sudo apt-get upgrade -y

The only solutions that I've seen to organize the external files into sub-folders has required the use of VBA to resolve a full path to the external file in the formulas. Here is a link to a site with several examples others have used:

http://www.teachexcel.com/excel-help/excel-how-to.php?i=415651

Alternatively, if you can place all of the files in the same folder instead of dividing them into sub-folders, then Excel will resolve the external references without requiring the use of VBA even if you move the files to a network location. Your formulas then become simply ='[ComponentsC.xlsx]Sheet1'!A1 with no folder names to traverse.

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

Slightly better version of the unique2 suggestion is below:

insert overwrite table target_table
select * from 
(
select stack(
    3,                 # generating new table with 3 records
    'John', 80,        # record_1
    'Bill', 61         # record_2
    'Martha', 101      # record_3
    ) 
) s;

Which does not require the hack with using an already exiting table.

Define 'better'. A synchronized block is only better because it allows you to:

1. Synchronize on a different object
2. Limit the scope of synchronization

Now your specific example is an example of the double-checked locking pattern which is suspect (in older Java versions it was broken, and it is easy to do it wrong).

If your initialization is cheap, it might be better to initialize immediately with a final field, and not on the first request, it would also remove the need for synchronization.

Regarding commits, refs, branches and "et cetera", Magnus answer just works (git remote update).

But unfortunately there is no way to clone / mirror / update the hooks, as I wanted...

I have found this very interesting thread about cloning/mirroring the hooks:

http://kerneltrap.org/mailarchive/git/2007/8/28/256180/thread

I learned:

• The hooks are not considered part of the repository contents.

• There is more data, like the .git/description folder, which does not get cloned, just as the hooks.

• The default hooks that appear in the hooks dir comes from the TEMPLATE_DIR

• There is this interesting template feature on git.

So, I may either ignore this "clone the hooks thing", or go for a rsync strategy, given the purposes of my mirror (backup + source for other clones, only).

Well... I will just forget about hooks cloning, and stick to the git remote update way.

• Sehe has just pointed out that not only "hooks" aren't managed by the clone / update process, but also stashes, rerere, etc... So, for a strict backup, rsync or equivalent would really be the way to go. As this is not really necessary in my case (I can afford not having hooks, stashes, and so on), like I said, I will stick to the remote update.

Thanks! Improved a bit of my own "git-fu"... :-)

This is the answer for the question.Reason for the cause is my LDAP string was wrong.

    try
    {
        string adServer = ConfigurationManager.AppSettings["Server"];
        string adDomain = ConfigurationManager.AppSettings["Domain"];
        string adUsername = ConfigurationManager.AppSettings["AdiminUsername"];
        string password = ConfigurationManager.AppSettings["Password"];
        string[] dc = adDomain.Split('.');
        string dcAdDomain = string.Empty;

        foreach (string item in dc)
        {
            if (dc[dc.Length - 1].Equals(item))
                dcAdDomain = dcAdDomain + "DC=" + item;
            else
                dcAdDomain = dcAdDomain + "DC=" + item + ",";
        }

        DirectoryEntry de = new DirectoryEntry("LDAP://" + adServer + "/CN=Users," + dcAdDomain, adUsername, password);

        DirectorySearcher ds = new DirectorySearcher(de);

        ds.SearchScope = SearchScope.Subtree;

        ds.Filter = "(&(objectClass=User)(sAMAccountName=" + username + "))";

        if (ds.FindOne() != null)
            return true;
    }
    catch (Exception ex)
    {
        ExLog(ex);
    }
    return false;

You can use not(expression) function

not() is a function in xpath (as opposed to an operator)

Example:

//a[not(contains(@id, 'xx'))]

OR

expression != true()

This question might have been answered here. There might be some potential issues when event propagation is interrupted, as explained by Philip Walton in this post.

A better approach/solution would be to create a custom jQuery event, e.g. clickoutside. Ben Alman has a great post (here) that explains how to implement one (and also explains how special events work), and he's got a nice implementation of it (here).

More reading on jQuery events API and jQuery special events:

• Introduction to custom events
• jQuery event extensions

You can use fuser to get what you want to be done.

In order to obtain the process ids of the tasks running on a port you can do:

fuser <<target_port>>/tcp

Let's say the port is 8888, the command becomes:

fuser 8888/tcp

And to kill a process that is running on a port, simply add -k switch.

fuser <<target_port>>/tcp -k

Example (port is 8888):

fuser 8888/tcp -k

That's it! It will close the process listening on the port. I usually do this before running my server application.

Update: Sep 2019

As a few people have mentioned, the parameters in paramMap should be accessed using the common MapAPI:

To get a snapshot of the params, when you don't care that they may change:

this.bankName = this.route.snapshot.paramMap.get('bank');

To subscribe and be alerted to changes in the parameter values (typically as a result of the router's navigation)

this.route.paramMap.subscribe( paramMap => {
    this.bankName = paramMap.get('bank');
})

Update: Aug 2017

Since Angular 4, params have been deprecated in favor of the new interface paramMap. The code for the problem above should work if you simply substitute one for the other.

Original Answer

If you inject ActivatedRoute in your component, you'll be able to extract the route parameters

    import {ActivatedRoute} from '@angular/router';
    ...
    
    constructor(private route:ActivatedRoute){}
    bankName:string;
    
    ngOnInit(){
        // 'bank' is the name of the route parameter
        this.bankName = this.route.snapshot.params['bank'];
    }

If you expect users to navigate from bank to bank directly, without navigating to another component first, you ought to access the parameter through an observable:

    ngOnInit(){
        this.route.params.subscribe( params =>
            this.bankName = params['bank'];
        )
    }

For the docs, including the differences between the two check out this link and search for "activatedroute"

No, it is not valid. But a "solution" can be creating a modal window outside of form "a" containing the form "b".

<div id="myModalFormB" class="modal">
    <form action="b">
        <input.../>
        <input.../>
        <input.../>
        <button type="submit">Save</button>
    </form>
</div>

<form action="a">
    <input.../>
    <a href="#myModalFormB">Open modal b </a>
    <input.../>
</form>

It can be easily done if you are using bootstrap or materialize css. I'm doing this to avoid using iframe.

The way you should be doing it in React Native (as I understand it), is by saving your 'global' variable in your index.js, for example. From there you can then pass it down using props.

Example:

    class MainComponent extends Component {

        componentDidMount() {
            //Define some variable in your component
            this.variable = "What's up, I'm a variable";
        }
        ...
        render () {
            <Navigator
                renderScene={(() => {
                    return(
                        <SceneComponent
                                //Pass the variable you want to be global through here
                                myPassedVariable={this.variable}/>
                    );
                })}/>
        }
    }


    class SceneComponent extends Component {

        render() {
            return(
                <Text>{this.props.myPassedVariable}</Text>
            );
        }

    }

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

required is a reflected property (like id, name, type, and such), so:

element.required = true;

...where element is the actual input DOM element, e.g.:

document.getElementById("edName").required = true;

(Just for completeness.)

Re:

Then the attribute's value is not the empty string, nor the canonical name of the attribute:

edName.attributes.required = [object Attr]

That's because required in that code is an attribute object, not a string; attributes is a NamedNodeMap whose values are Attr objects. To get the value of one of them, you'd look at its value property. But for a boolean attribute, the value isn't relevant; the attribute is either present in the map (true) or not present (false).

So if required weren't reflected, you'd set it by adding the attribute:

element.setAttribute("required", "");

...which is the equivalent of element.required = true. You'd clear it by removing it entirely:

element.removeAttribute("required");

...which is the equivalent of element.required = false.

But we don't have to do that with required, since it's reflected.

Just Follow this to Insert values into database

//Connection String

  con.Open();

sqlQuery = "INSERT INTO [dbo].[Client] ([Client_ID],[Client_Name],[Phone],[Address],[Image]) VALUES('" + txtClientID.Text + "','" + txtClientName.Text + "','" + txtPhoneno.Text + "','" + txtaddress.Text + "',@image)";

                cmd = new SqlCommand(sqlQuery, con);
                cmd.Parameters.Add("@image", SqlDbType.Image);
                cmd.Parameters["@image"].Value = img;
            //img is a byte object
           ** /*MemoryStream ms = new MemoryStream();
            pictureBox1.Image.Save(ms,pictureBox1.Image.RawFormat);
            byte[] img = ms.ToArray();*/**

                cmd.ExecuteNonQuery();
                con.Close();

The most simple solution android supported now!

Use custom font in xml:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="@font/[your font resource]"/>

look details:

https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml.html

In my opinion the best tool for such testing is curl. Its --upload-file option uploads a file by PUT, which is exactly what you want (and it can do much more, like modifying HTTP headers, in case you need it):

curl http://myservice --upload-file file.txt

I got few links sometime back while reading on ExtJS full framework in itself is JSON.

http://www.thomasfrank.se/xml_to_json.html

http://camel.apache.org/xmljson.html

online XML to JSON converter : http://jsontoxml.utilities-online.info/

UPDATE BTW, To get JSON as added in question, HTML need to have type & content tags in it too like this or you need to use some xslt transformation to add these elements while doing JSON conversion

<?xml version="1.0" encoding="UTF-8" ?>
<type>div</type>
<content>
    <type>span</type>
    <content>Text2</content>
</content>
<content>Text2</content>

The answers are already kind of outdated or not complete. This maybe works for non-protected apks (no Proguard), but nowadays nobody deploys an unprotected apk. The way I was able to modify a (my) well-protected apk (Proguard, security check which checks for "hacking tools", security check, which checks if the app is repackaged with debug mode,...) is via apktool as already mentioned by other ones here. But nobody explained, that you have to sign the app again.

apktool d app.apk
//generates a folder with smali bytecode files. 

//Do something with it.

apktool b [folder name] -o modified.apk
//generates the modified apk.

//and then
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore modified.apk androiddebugkey
//signs the app the the debug key (the password is android)

//this apk can be installed on a device.

In my test, the original release apk had no logging. After I decompiled with apktool I exchanged a full byte code file without logging by a full byte code file with logging, re-compiled and signed it and I was able to install it on my device. Afterwards I was able to see the logs in Android Studio as I connected the app to it.

In my opinion, decompiling with dex2jar and JD-GUI is only helpful to get a better understanding what the classes are doing, just for reading purposes. But since everything is proguarded, I'm not sure that you can ever re-compile this half-baked Java code to a working apk. If so, please let me know. I think, the only way is to manipulate the byte code itself as mentioned in this example.

I would put each element that you want inline inside a separate col-md-* div within your row. Or force your elements to display inline. The form-control class displays block because that's the way bootstrap thinks it should be done.

Just used the Nathan's solution and it works fine. I needed to convert ISO-8859-1 to Unicode:

string isocontent = Encoding.GetEncoding("ISO-8859-1").GetString(fileContent, 0, fileContent.Length);
byte[] isobytes = Encoding.GetEncoding("ISO-8859-1").GetBytes(isocontent);
byte[] ubytes = Encoding.Convert(Encoding.GetEncoding("ISO-8859-1"), Encoding.Unicode, isobytes);
return Encoding.Unicode.GetString(ubytes, 0, ubytes.Length);

SELECT * 
FROM 
    PersonAddress a, 
    Person b,
    PersonAdmin c
WHERE a.addressid LIKE '97%' 
    AND b.lastname LIKE 'test%'
    AND b.genderid IS NOT NULL
    AND a.partyid = c.partyid 
    AND b.partyid = c.partyid;

The answer with the higher vote has a mistake. when I used it I find out it in line 3 :

var counter = jsonData.counters[i];

I changed it to :

var counter = jsonData[i].counters;

and it worked for me. There is a difference to the other answers in line 3:

var jsonData = JSON.parse(myMessage);
for (var i = 0; i < jsonData.counters.length; i++) {
    var counter = jsonData[i].counters;
    console.log(counter.counter_name);
}

While it looks like your setup is correct, there are a few things to check:

1. The output of env - specifically PATH.
2. command -v java tells you what?
3. Is there a java executable in $JAVA_HOME\bin and does it have the execute bit set? If not chmod a+x java it.

I trust you have source'd your .profile after adding/changing the JAVA_HOME and PATH?

Also, you can help yourself in future maintenance of your JDK installation by writing this instead:

export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=$JAVA_HOME/bin:$PATH

Then you only need to update one env variable when you setup the JDK installation.

Finally, you may need to run hash -r to clear the Bash program cache. Other shells may need a similar command.

I solved these kinds of problems using the webdrive manager.

You can automatically use the correct chromedriver by using the webdrive-manager. Install the webdrive-manager:

pip install webdriver-manager

Then use the driver in python as follows

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

This answer is taken from https://stackoverflow.com/a/52878725/10741023

try with this:

var c=new Image("Path to the background image");
c.onload=function(){
   //render the form
}

With this code you preload the background image and render the form when it's loaded

For Bootstrap 4.x use display utilities:

w-100 d-print-block d-print-table

Usage:

<table class="table w-100 d-print-block d-print-table">

The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

column of first matrix = row of second matrix

and do not follow the below step

row of first matrix  = column of second matrix

it will throw an error

In the below code, df is the name of dataframe. 1st parameter is to show all rows in the dataframe dynamically rather than hardcoding a numeric value. The 2nd parameter will take care of displaying full column contents since the value is set as False.

df.show(df.count(),False)

SCALA

In the below code, df is the name of dataframe. 1st parameter is to show all rows in the dataframe dynamically rather than hardcoding a numeric value. The 2nd parameter will take care of displaying full column contents since the value is set as false.

df.show(df.count().toInt,false)

You can do it like this:

SELECT * FROM ... WHERE name LIKE 'someone'

(It's not the solution, but in some cases is very convenient)

"The LIKE operator does a pattern matching comparison. The operand to the right contains the pattern, the left hand operand contains the string to match against the pattern. A percent symbol ("%") in the pattern matches any sequence of zero or more characters in the string. An underscore ("_") in the pattern matches any single character in the string. Any other character matches itself or its lower/upper case equivalent (i.e. case-insensitive matching). (A bug: SQLite only understands upper/lower case for ASCII characters. The LIKE operator is case sensitive for unicode characters that are beyond the ASCII range. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.)."

Here's something I found:

:pingtheserver
ping %input% | find "Reply" > nul
if not errorlevel 1 (
    echo server is online, up and running.
) else (
    echo host has been taken down wait 3 seconds to refresh
    ping 1.1.1.1 -n 1 -w 3000 >NUL
    goto :pingtheserver
) 

Note that ping 1.1.1.1 -n -w 1000 >NUL will wait 1 second but only works when connected to a network

As @Eiríkr Útlendi noted, the accepted solution only considers two white space characters: the horizontal tab (U+0009), and a breaking space (U+0020). It does not consider other whitespace characters such as non-breaking spaces (which happen to be in the text I am trying to deal with). A more complete whitespace character listing is included on Wikipedia and also referenced in the linked Perl answer. A simple C# solution that accounts for these other characters can be built using character class subtraction

[\s-[\r\n]]

or, including Eiríkr Útlendi's solution, you get

[\s\u3000-[\r\n]]

Is gcc installed?

sudo yum install gcc

Both questions are answered in git status.

To unstage adding a new file use git rm --cached filename.ext

# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   test

To unstage deleting a file use git reset HEAD filename.ext

# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   deleted:    test

In the other hand, git checkout -- never unstage, it just discards non-staged changes.

You can specify how many times you want the previous item to match by using {min,max}.

{[0-9]{1,3}:[0-9]{1,3}}

Also, you can use \d for digits instead of [0-9] for most regex flavors:

{\d{1,3}:\d{1,3}}

You may also want to consider escaping the outer { and }, just to make it clear that they are not part of a repetition definition.

I have found it satisfactory to use ls and cd within ipython notebook to find the file. Then type cat your_file_name into the cell, and you'll get back the contents of the file, which you can then paste into the cell as code.

signal isn't the most reliable way as it differs in implementations. I would recommend using sigaction. Tom's code would now look like this :

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>

void my_handler(int s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{

   struct sigaction sigIntHandler;

   sigIntHandler.sa_handler = my_handler;
   sigemptyset(&sigIntHandler.sa_mask);
   sigIntHandler.sa_flags = 0;

   sigaction(SIGINT, &sigIntHandler, NULL);

   pause();

   return 0;    
}

Here is a static class implementing Start(), Stop(), and IsStarted() for IISExpress. It is parametrized by hard-coded static properties and passes invocation information via the command-line arguments to IISExpress. It uses the Nuget package, MissingLinq.Linq2Management, which surprisingly provides information missing from System.Diagnostics.Process, specifically, the command-line arguments that can then be used to help disambiguate possible multiple instances of IISExpress processes, since I don't preserve the process Ids. I presume there is a way to accomplish the same thing with just System.Diagnostics.Process, but life is short. Enjoy.

additional info:

http://maps.google.com/maps?q=loc: put in latitude and longitude after, example:

http://maps.google.com/maps?q=loc:51.03841,-114.01679

this will show pointer on map, but will suppress geocoding of the address, best for a location without an address, or for a location where google maps shows the incorrect address.

I´ve done a tiny solution using only jQuery.

First, you need to put an additional class to your <div class="modal-body"> I called "ativa-scroll", so it becomes something like this:

<div class="modal-body ativa-scroll">

So now just put this piece of code on your page, near your JS loading:

<script type="text/javascript">
  $(document).ready(ajustamodal);
  $(window).resize(ajustamodal);
  function ajustamodal() {
    var altura = $(window).height() - 155; //value corresponding to the modal heading + footer
    $(".ativa-scroll").css({"height":altura,"overflow-y":"auto"});
  }
</script>

I works perfectly for me, also in a responsive way! :)

You can try using parentheses around the OR expressions to make sure your query is interpreted correctly, or more concisely, use IN:

SELECT ads.*, location.county 
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1 
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)

You can also drag and drop the folder from Windows Explorer onto your Visual Studio solution window.

I have found a npm package made with CoffeeScript that has a lot of incredible useful helpers for Handlebars. Take a look of the documentation in the following URL:

https://npmjs.org/package/handlebars-helpers

You can do a wget http://registry.npmjs.org/handlebars-helpers/-/handlebars-helpers-0.2.6.tgz to download them and see the contents of the package.

You will be abled to do things like {{#is number 5}} or {{formatDate date "%m/%d/%Y"}}

For someone who needs quick reference of C# Escape Sequences that can be used in string literals:

\t     Horizontal tab (ASCII code value: 9)

\n     Line feed (ASCII code value: 10)

\r     Carriage return (ASCII code value: 13)

\'     Single quotation mark

\"     Double quotation mark

\\     Backslash

\?     Literal question mark

\x12     ASCII character in hexadecimal notation (e.g. for 0x12)

\x1234     Unicode character in hexadecimal notation (e.g. for 0x1234)

It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline which gets adjusted to current OS settings. With .Net Core it gets really important.

Lots of things you could do.

s.substring(s.lastIndexOf(':') + 1);

will get everything after the last colon.

s.substring(s.lastIndexOf(' ') + 1);

everything after the last space.

String numbers[] = s.split("[^0-9]+");

splits off all sequences of digits; the last element of the numbers array is probably what you want.

Using RxJs, you can declare a Subject in your parent component and pass it as Observable to child component, child component just need to subscribe to this Observable.

Parent-Component

eventsSubject: Subject<void> = new Subject<void>();

emitEventToChild() {
  this.eventsSubject.next();
}

Parent-HTML

<child [events]="eventsSubject.asObservable()"> </child>    

Child-Component

private eventsSubscription: Subscription;

@Input() events: Observable<void>;

ngOnInit(){
  this.eventsSubscription = this.events.subscribe(() => doSomething());
}

ngOnDestroy() {
  this.eventsSubscription.unsubscribe();
}

Here is a post which introduces different types of keystore in Java and the differences among different types of keystore. http://www.pixelstech.net/article/1408345768-Different-types-of-keystore-in-Java----Overview

Below are the descriptions of different keystores from the post:

JKS, Java Key Store. You can find this file at sun.security.provider.JavaKeyStore. This keystore is Java specific, it usually has an extension of jks. This type of keystore can contain private keys and certificates, but it cannot be used to store secret keys. Since it's a Java specific keystore, so it cannot be used in other programming languages.

JCEKS, JCE key store. You can find this file at com.sun.crypto.provider.JceKeyStore. This keystore has an extension of jceks. The entries which can be put in the JCEKS keystore are private keys, secret keys and certificates.

PKCS12, this is a standard keystore type which can be used in Java and other languages. You can find this keystore implementation at sun.security.pkcs12.PKCS12KeyStore. It usually has an extension of p12 or pfx. You can store private keys, secret keys and certificates on this type.

PKCS11, this is a hardware keystore type. It servers an interface for the Java library to connect with hardware keystore devices such as Luna, nCipher. You can find this implementation at sun.security.pkcs11.P11KeyStore. When you load the keystore, you no need to create a specific provider with specific configuration. This keystore can store private keys, secret keys and cetrificates. When loading the keystore, the entries will be retrieved from the keystore and then converted into software entries.

With Chris's inspiring post here:

https://css-tricks.com/different-transitions-for-hover-on-hover-off/

I managed to come up with this:

#banner
{
    display:block;
    width:100%;
    background-repeat:no-repeat;
    background-position:center bottom;
    background-image:url(../images/image1.jpg);
    /* HOVER OFF */
    @include transition(background-image 0.5s ease-in-out); 

    &:hover
    {
        background-image:url(../images/image2.jpg);
        /* HOVER ON */
        @include transition(background-image 0.5s ease-in-out); 
    }
}

To use cache-control in HTML, you use the meta tag, e.g.

<meta http-equiv="Cache-control" content="public">

The value in the content field is defined as one of the four values below.

Some information on the Cache-Control header is as follows

HTTP 1.1. Allowed values = PUBLIC | PRIVATE | NO-CACHE | NO-STORE.

Public - may be cached in public shared caches.
Private - may only be cached in private cache.
No-Cache - may not be cached.
No-Store - may be cached but not archived.

The directive CACHE-CONTROL:NO-CACHE indicates cached information should not be used and instead requests should be forwarded to the origin server. This directive has the same semantics as the PRAGMA:NO-CACHE.

Clients SHOULD include both PRAGMA: NO-CACHE and CACHE-CONTROL: NO-CACHE when a no-cache request is sent to a server not known to be HTTP/1.1 compliant. Also see EXPIRES.

Note: It may be better to specify cache commands in HTTP than in META statements, where they can influence more than the browser, but proxies and other intermediaries that may cache information.

This is my final code .... (based on previous fixes, thank you big time for headstart, saved a lot of time experimenting). What bugged me was scrolling up, as well as scrolling down ... :)

it always makes me wonder how jquery can be elegant!!!

$(document).ready(function(){

    //run once
    var el=$('#scrolldiv');
    var originalelpos=el.offset().top; // take it where it originally is on the page

    //run on scroll
     $(window).scroll(function(){
        var el = $('#scrolldiv'); // important! (local)
        var elpos = el.offset().top; // take current situation
        var windowpos = $(window).scrollTop();
        var finaldestination = windowpos+originalelpos;
        el.stop().animate({'top':finaldestination},500);
     });

});

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Datatables supports HTML5 data-* attributes for this functionality.

It supports multiple columns in the sort order (it's 0-based)

<table data-order="[[ 1, 'desc' ], [2, 'asc' ]]">
    <thead>
        <tr>
            <td>First</td>
            <td>Another column</td>
            <td>A third</td>
        </tr>
    </thead>

Now my jQuery is simply $('table').DataTables(); and I get my second and third columns sorted in desc / asc order.

Here's some other nice attributes for the <table> that I find myself reusing:

data-page-length="-1" will set the page length to All (pass 25 for page length 25)...

data-fixed-header="true" ... Make a guess

} means move cursor to next paragraph. so, use v} to select entire paragraph.

Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.

New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.

Try to uncheck the CheckBox “Use Managed Compatibility Mode” in

Tools => Options => Debugging => General

It worked for me.

Guess what? @BenCreasy was totally right!!

Starting version 1.12.0 of jQuery we can do this:

$.post({
    url: yourURL,
    data: yourData,
    contentType: 'application/json; charset=utf-8'
})
    .done(function (response) {
        //Do something on success response...
    });

I just tested it and it worked!!

I'm not sure if I understand but I'm guessing that you're trying to show a MessageBox from ASP.Net?

If so, this code project article might be helpful: Simple MessageBox functionality in ASP.NET

For me there was an issue in that I want to distinguish between alpha, numeric and alpha numeric, so to ensure an alphanumeric string contains at least one alpha and at least one numeric, I used :

^([a-zA-Z_]{1,}\d{1,})+|(\d{1,}[a-zA-Z_]{1,})+$

SHOW TABLE_NAME is not valid. Try SHOW TABLES

You can check the implementation of CPython's dicttype on GitHub. This is the signature of method that implements the dict iterator:

_PyDict_Next(PyObject *op, Py_ssize_t *ppos, PyObject **pkey,
             PyObject **pvalue, Py_hash_t *phash)

CPython dictobject.c

I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.

It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.

To convert integer to char only 0 to 9 will be converted. As we know 0's ASCII value is 48 so we have to add its value to the integer value to convert in into the desired character hence

int i=5;
char c = i+'0';

Yes. bar.a and bar.b are set to true, but bar.c is undefined. However, certain compilers will set it to false.

See a live example here: struct demo

According to C++ standard Section 8.5.12:

if no initialization is performed, an object with automatic or dynamic storage duration has indeterminate value

For primitive built-in data types (bool, char, wchar_t, short, int, long, float, double, long double), only global variables (all static storage variables) get default value of zero if they are not explicitly initialized.

If you don't really want undefined bar.c to start with, you should also initialize it like you did for bar.a and bar.b.
