You can use Newtonsoft library and use it as follows

using Newtonsoft.Json;



public class jb
{
     public DateTime Date { set; get; }
     public string Artist { set; get; }
     public int Year { set; get; }
     public string album { set; get; }

}
var jsonObject = new jb();

jsonObject.Date = DateTime.Now;
jsonObject.Album = "Me Against The World";
jsonObject.Year = 1995;
jsonObject.Artist = "2Pac";


System.Web.Script.Serialization.JavaScriptSerializer oSerializer =
         new System.Web.Script.Serialization.JavaScriptSerializer();

string sJSON = oSerializer.Serialize(jsonObject );

It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.

Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.

DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj

...

The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.

var DyObjectsList = new List<dynamic>; 
if (condition1) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = true; 
    DyObj.Message = "Message 1"; 
    DyObjectsList .Add(DyObj); 
} 
if (condition2) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = false; 
    DyObj.Message = "Message 2"; 
    DyObjectsList .Add(DyObj); 
} 

your resulting List essentially looks like this

DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj

Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.

However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.

An easy solution to overcome this problem is to set your default encoding to utf8. Follow is an example

import sys

reload(sys)
sys.setdefaultencoding('utf8')

i think this add new property in desired type without having to set a primitive value, like when property defined in class definition

var x = new ExpandoObject();
x.NewProp = default(string)

Anonymous types are just regular types that are implicitly declared. They have little to do with dynamic.

Now, if you were to use an ExpandoObject and reference it through a dynamic variable, you could add or remove fields on the fly.

edit

Sure you can: just cast it to IDictionary<string, object>. Then you can use the indexer.

You use the same casting technique to iterate over the fields:

dynamic employee = new ExpandoObject();
employee.Name = "John Smith";
employee.Age = 33;

foreach (var property in (IDictionary<string, object>)employee)
{
    Console.WriteLine(property.Key + ": " + property.Value);
}
// This code example produces the following output:
// Name: John Smith
// Age: 33

The above code and more can be found by clicking on that link.

There are several scenarios to consider. First of all, you need to check the type of your object. You can simply call GetType() for this. If the type does not implement IDynamicMetaObjectProvider, then you can use reflection same as for any other object. Something like:

var propertyInfo = test.GetType().GetProperties();

However, for IDynamicMetaObjectProvider implementations, the simple reflection doesn't work. Basically, you need to know more about this object. If it is ExpandoObject (which is one of the IDynamicMetaObjectProvider implementations), you can use the answer provided by itowlson. ExpandoObject stores its properties in a dictionary and you can simply cast your dynamic object to a dictionary.

If it's DynamicObject (another IDynamicMetaObjectProvider implementation), then you need to use whatever methods this DynamicObject exposes. DynamicObject isn't required to actually "store" its list of properties anywhere. For example, it might do something like this (I'm reusing an example from my blog post):

public class SampleObject : DynamicObject
{
    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = binder.Name;
        return true;
    }
}

In this case, whenever you try to access a property (with any given name), the object simply returns the name of the property as a string.

dynamic obj = new SampleObject();
Console.WriteLine(obj.SampleProperty);
//Prints "SampleProperty".

So, you don't have anything to reflect over - this object doesn't have any properties, and at the same time all valid property names will work.

I'd say for IDynamicMetaObjectProvider implementations, you need to filter on known implementations where you can get a list of properties, such as ExpandoObject, and ignore (or throw an exception) for the rest.

After valueTuples, what's the use of ExpandoObject class? this 6 lines code with ExpandoObject:

dynamic T = new ExpandoObject();
T.x = 1;
T.y = 2;
T.z = new ExpandoObject();
T.z.a = 3;
T.b= 4;

can be written in one line with tuples:

var T = (x: 1, y: 2, z: (a: 3, b: 4));

besides with tuple syntax you have strong type inference and intlisense support

Yes we do it all the time. You return a static instance rather than a new Object

 static Direction getOppositeDirection(Direction d){
       Direction result = null;
       if (d != null){
           int newCode = -d.getCode();
           for (Direction direction : Direction.values()){
               if (d.getCode() == newCode){
                   result = direction;
               }
           }
       }
       return result;
 }

For those who stumble upon this from a search (Google) and are trying to translate to .NET and MVC code. (as in my case)

@using (Html.BeginForm("RemoveLostRolls", "Process", FormMethod.Get)) {
     <input type="submit" value="Process" />
}

This will show a button labeled "Process" and take you to "/Process/RemoveLostRolls". Without "FormMethod.Get" it worked, but was seen as a "post".

First off all I would like to thanks @MaximShoustin.

Thanks of you I have really nice table.

I provide some small modification in $scope.range and $scope.setPage.

In this way I have now possibility to go to the last page or come back to the first page. Also when I'm going to next or prev page the navigation is changing when $scope.gap is crossing. And the current page is not always on first position. For me it's looking more nicer.

Here is the new fiddle example: http://jsfiddle.net/qLBRZ/3/

we can query the msdb in many ways to get the details.

few are

select job.Name, job.job_ID, job.Originating_Server,activity.run_requested_Date,
datediff(minute, activity.run_requested_Date, getdate()) as Elapsed 
from msdb.dbo.sysjobs_view job 
inner join msdb.dbo.sysjobactivity activity on (job.job_id = activity.job_id) 
where run_Requested_date is not null 
and stop_execution_date is null 
and job.name like 'Your Job Prefix%'

To lessen the impact on code readabilty, I'd suggest:

v = 1d* s/t;

When you commit, tick the Optimize imports option on the right. This will become the default until you change it.

I prefer using the Reformat code option as well.

There is a library called BoofCV which claims to better than ZBar and other libraries.
Here are the steps to use that (any OS).

Pre-requisites:

• Ensure JDK 14+ is installed and set in $PATH
• pip install pyboof

Class to decode:

import os
import numpy as np
import pyboof as pb

pb.init_memmap() #Optional

class QR_Extractor:
    # Src: github.com/lessthanoptimal/PyBoof/blob/master/examples/qrcode_detect.py
    def __init__(self):
        self.detector = pb.FactoryFiducial(np.uint8).qrcode()
    
    def extract(self, img_path):
        if not os.path.isfile(img_path):
            print('File not found:', img_path)
            return None
        image = pb.load_single_band(img_path, np.uint8)
        self.detector.detect(image)
        qr_codes = []
        for qr in self.detector.detections:
            qr_codes.append({
                'text': qr.message,
                'points': qr.bounds.convert_tuple()
            })
        return qr_codes

Usage:

qr_scanner = QR_Extractor()
output = qr_scanner.extract('Your-Image.jpg')
print(output)

Tested and works on Python 3.8 (Windows & Ubuntu)

One reason to use pointers is so that a variable or an object can be modified in a called function.

In C++ it is a better practice to use references than pointers. Though references are essentially pointers, C++ to some extent hides the fact and makes it seem as if you are passing by value. This makes it easy to change the way the calling function receives the value without having to modify the semantics of passing it.

Consider the following examples:

Using references:

public void doSomething()
{
    int i = 10;
    doSomethingElse(i);  // passes i by references since doSomethingElse() receives it
                         // by reference, but the syntax makes it appear as if i is passed
                         // by value
}

public void doSomethingElse(int& i)  // receives i as a reference
{
    cout << i << endl;
}

Using pointers:

public void doSomething()
{
    int i = 10;
    doSomethingElse(&i);
}

public void doSomethingElse(int* i)
{
    cout << *i << endl;
}

There is a single line solution for those who use jQuery:

$("link[rel*='icon']").prop("href",'https://www.stackoverflow.com/favicon.ico');

using System.Diagnostics;
...

var st = new StackTrace();
var sf = st.GetFrame(0);

var currentMethodName = sf.GetMethod();

Or, if you'd like to have a helper method:

[MethodImpl(MethodImplOptions.NoInlining)]
public string GetCurrentMethod()
{
    var st = new StackTrace();
    var sf = st.GetFrame(1);

    return sf.GetMethod().Name;
}

in my case, I need to have my wcf running for more than 2 hours. Setting and did not work at all. The wcf did not execute longer than maybe 20~30 minutes. So I changed the idle timeout setting of application pool in IIS manager then it worked! In IIS manager, choose your application pool and right click on it and choose advanced settings then change the idle timeout setting to any minutes you want. So, I think setting the web.config and setting the application pool are both needed.

The right mental model for using mutexes: The mutex protects an invariant.

Why are you sure that this is really right mental model for using mutexes? I think right model is protecting data but not invariants.

The problem of protecting invariants presents even in single-threaded applications and has nothing common with multi-threading and mutexes.

Furthermore, if you need to protect invariants, you still may use binary semaphore wich is never recursive.

These steps are working on CentOS 6.5 so they should work on CentOS 7 too:

(EDIT - exactly the same steps work for MariaDB 10.3 on CentOS 8)

1. yum remove mariadb mariadb-server
2. rm -rf /var/lib/mysql If your datadir in /etc/my.cnf points to a different directory, remove that directory instead of /var/lib/mysql
3. rm /etc/my.cnf the file might have already been deleted at step 1
4. Optional step: rm ~/.my.cnf
5. yum install mariadb mariadb-server

[EDIT] - Update for MariaDB 10.1 on CentOS 7

The steps above worked for CentOS 6.5 and MariaDB 10.

I've just installed MariaDB 10.1 on CentOS 7 and some of the steps are slightly different.

Step 1 would become:

yum remove MariaDB-server MariaDB-client

Step 5 would become:

yum install MariaDB-server MariaDB-client

The other steps remain the same.

The MVC 5 stock install puts javascript references in the _Layout.cshtml file that is shared in all pages. So the javascript files were below the main content and document.ready function where all my $'s were.

BOTTOM PART OF _Layout.cshtml:

    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)

</body>
</html>

I moved them above the @RenderBody() and all was fine.

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)

    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

</body>
</html>

I had a similar issue when not using inline for my global function that was included in two places.

If you are using a "Standard TCP/IP over SSH" type of connection, under "Preferences"->"Others" there is "SSH KeepAlive" field. It took me quite a while to find it :(

Expanding on this method, applied to finding the mode of the data where you may need the index of the actual array to see how far away the value is from the center of the distribution.

(_, idx, counts) = np.unique(a, return_index=True, return_counts=True)
index = idx[np.argmax(counts)]
mode = a[index]

Remember to discard the mode when len(np.argmax(counts)) > 1, also to validate if it is actually representative of the central distribution of your data you may check whether it falls inside your standard deviation interval.

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:

    <profile>
        <id>alternateBuildDir</id>
        <activation>
            <property>
                <name>alt.build.dir</name>
            </property>
        </activation>
        <build>
            <directory>${alt.build.dir}</directory>
        </build>
    </profile>

Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.

Most *nixen understand the environment variable 'http_proxy' when performing web requests.

export http_proxy=http://my-proxy-server.com:8080/
svn co http://code.sixapart.com/svn/perlball/

should do the trick. Most http libraries check for this (and other) environment variables.

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

Use shortcut: Ctrl+Q. You can customize in Settings

int i = 7122960;
decimal d = (decimal)i / 100;

OK, it took me a while to read all the answers and links. Here's what I got out of them:

Sample Results

The accepted answer disables visual styles, it does allow you to set the color to anything you want, but the result looks plain:

Using the following method, you can get something like this instead:

How To

First, include this if you haven't: using System.Runtime.InteropServices;

Second, you can either create this new class, or put its code into an existing static non-generic class:

public static class ModifyProgressBarColor
{
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
    static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr w, IntPtr l);
    public static void SetState(this ProgressBar pBar, int state)
    {
        SendMessage(pBar.Handle, 1040, (IntPtr)state, IntPtr.Zero);
    }
}

Now, to use it, simply call:

progressBar1.SetState(2);

Note the second parameter in SetState, 1 = normal (green); 2 = error (red); 3 = warning (yellow).

Hope it helps!

Problem here is you are trying to open a mongo shell without starting a mongo db which is listening to port 127.0.0.1:27017(deafault for mongo db) thats what the error is all about:

Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect failed

The easiest solution is to open the terminal and type

$ mongod --dbpath ~/data/db

Note: dbpath here is "Users/user" where data/db directories are created

i.e., you need to create directory data and sub directory db in your user folder. For e.g say `

/Users/johnny/data

After mongo db is up. Open another terminal in new window and type

$ mongo

it will open mongo shell with your mongo db connection opened in another terminal.

There's a method called getBytes(). Use it wisely .

The phpqrcode library is really fast to configure and the API documentation is easy to understand.

In addition to abaumg's answer I have attached 2 examples in PHP from http://phpqrcode.sourceforge.net/examples/index.php

1. QR code encoder

first include the library from your local path

include('../qrlib.php');

then to output the image directly as PNG stream do for example:

QRcode::png('your texte here...');

to save the result locally as a PNG image:

$tempDir = EXAMPLE_TMP_SERVERPATH;

$codeContents = 'your message here...';

$fileName = 'qrcode_name.png';

$pngAbsoluteFilePath = $tempDir.$fileName;
$urlRelativeFilePath = EXAMPLE_TMP_URLRELPATH.$fileName;

QRcode::png($codeContents, $pngAbsoluteFilePath); 

2. QR code decoder

See also the zxing decoder:

http://zxing.org/w/decode.jspx

Pretty useful to check the output.

3. List of Data format

A list of data format you can use in your QR code according to the data type :

• Website URL: http://stackoverflow.com (including the protocole http://)
• email address: mailto:[email protected]
• Telephone Number: +16365553344 (including country code)
• SMS Message: smsto:number:message
• MMS Message: mms:number:subject
• YouTube Video: youtube://ID (may work on iPhone, not standardized)

mandatory parts:

tbody {
    overflow-y: scroll;  (could be: 'overflow: scroll' for the two axes)
    display: block;
    with: xxx (a number or 100%)
}

thead {
    display: inline-block;
}

The counter in your for loop appears incorrect (or we're missing some code). Here's a working Fiddle.

This code:

//Where is counter[0] initialized?
for (i ; i < counter[0].value; i++)

Should be replaced with:

var timeTempCount = 5; //I'm not sure where you're getting this value so I set it.

for (var i = 0; i <= timeTempCount; i++)

an ajax call to your domain is the easiest way to detect if you are offline

$.ajax({
      type: "HEAD",
      url: document.location.pathname + "?param=" + new Date(),
      error: function() { return false; },
      success: function() { return true; }
   });

this is just to give you the concept, it should be improved.

E.g. error=404 should still mean that you online

In Kotlin

private fun removeLastChar(str: String?): String? {
    return if (str == null || str.isEmpty()) str else str.substring(0, str.length - 1)
}

You must use an aggregate function on the columns against which you are not grouping. In this example, I arbitrarily picked the Min function. You are combining the rows with the same FruitType value. If I have two rows with the same FruitType value but different Fruit_Id values for example, what should the system do?

Select Min(tblFruit_id) As tblFruit_id
    , tblFruit_FruitType
From tblFruit
Group By tblFruit_FruitType

SQL Fiddle example

In Windows 7, right-click on Computer -> Properties -> Advanced system settings; then in the Advanced tab, click Environment Variables... -> System variables -> New....

Give the new system variable the name JAVA_HOME and the value C:\Program Files\Java\jdk1.7.0_79 (depending on your JDK installation path it varies).

Then select the Path system variable and click Edit.... Keep the variable name as Path, and append C:\Program Files\Java\jdk1.7.0_79\bin; or %JAVA_HOME%\bin; (both mean the same) to the variable value.

Once you are done with above changes, try below steps. If you don't see similar results, restart the computer and try again. If it still doesn't work you may need to reinstall JDK.

Open a Windows command prompt (Windows key + R -> enter cmd -> OK), and check the following:

java -version

You will see something like this:

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

Then check the following:

javac -version

You will see something like this:

javac 1.7.0_79

You can try using this code:

protected ServiceConnection mServerConn = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder binder) {
        Log.d(LOG_TAG, "onServiceConnected");
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        Log.d(LOG_TAG, "onServiceDisconnected");
    }
}

public void start() {
    // mContext is defined upper in code, I think it is not necessary to explain what is it 
    mContext.bindService(intent, mServerConn, Context.BIND_AUTO_CREATE);
    mContext.startService(intent);
}

public void stop() {
    mContext.stopService(new Intent(mContext, ServiceRemote.class));
    mContext.unbindService(mServerConn);
}

I'm rusty with structs, so I'm probably missing a few keywords here. But why not start with a global structure with the defaults initialized, copy it to your local variable, then modify it?

An initializer like:

void init_struct( structType * s )
{
   memcopy(s,&defaultValues,sizeof(structType));
}

Then when you want to use it:

structType foo;
init_struct( &foo ); // get defaults
foo.fieldICareAbout = 1; // modify fields
update( &foo ); // pass to function

I dont know if this useful for you when you resize your page:

$(window).resize(function() {
       if(screen.width == window.innerWidth){
           alert("you are on normal page with 100% zoom");
       } else if(screen.width > window.innerWidth){
           alert("you have zoomed in the page i.e more than 100%");
       } else {
           alert("you have zoomed out i.e less than 100%");
       }
    });

You need to surround $file = readdir($handle) with parentheses.

Here you go:

$log_directory = 'your_dir_name_here';

$results_array = array();

if (is_dir($log_directory))
{
        if ($handle = opendir($log_directory))
        {
                //Notice the parentheses I added:
                while(($file = readdir($handle)) !== FALSE)
                {
                        $results_array[] = $file;
                }
                closedir($handle);
        }
}

//Output findings
foreach($results_array as $value)
{
    echo $value . '<br />';
}

This is not an issue, this is a design of Android. See here:

You should design each fragment as a modular and reusable activity component. That is, because each fragment defines its own layout and its own behavior with its own lifecycle callbacks, you can include one fragment in multiple activities, so you should design for reuse and avoid directly manipulating one fragment from another fragment.

A possible workaround would be to do something like this in your MainActivity:

Fragment someFragment;    

...onCreate etc instantiating your fragments

public void myClickMethod(View v){
    someFragment.myClickMethod(v);
}

and then in your Fragment class:

public void myClickMethod(View v){
    switch(v.getid()){
       // Your code here
    }
 } 

I use mobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)

Here's yet another option to add to the mix:

$ du -b file.txt

That is: estimate file space usage of file.txt in bytes.

• A ref variable needs to be initialized before passing it in.
• An out variable needs to be set in your function implementation
• out parameters can be thought of as additional return variables (not input)
• ref parameters can be thought of as both input and output variables.

When installing Apache and PHP under Ubuntu 14.04, I needed to specifically enable php configs by issuing a2enmod php5-cgi

This must work!

client (angular):

$scope.saveForm = function () {
      var formData = new FormData();
      var file = $scope.myFile;
      var json = $scope.myJson;
      formData.append("file", file);
      formData.append("ad",JSON.stringify(json));//important: convert to JSON!
      var req = {
        url: '/upload',
        method: 'POST',
        headers: {'Content-Type': undefined},
        data: formData,
        transformRequest: function (data, headersGetterFunction) {
          return data;
        }
      };

Backend-Spring Boot:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
    public @ResponseBody
    Advertisement storeAd(@RequestPart("ad") String adString, @RequestPart("file") MultipartFile file) throws IOException {

        Advertisement jsonAd = new ObjectMapper().readValue(adString, Advertisement.class);
//do whatever you want with your file and jsonAd

document.location is an object, not a string. It returns (by default) the full path, but it actually holds more info than that.

Shortcut for solution: document.location.toString().substring(2,3);

Or use document.location.href or window.location.href

Your usage of now() is correct. However, you need to use one type of quotes around the entire query and another around the values.

You can modify your query to use double quotes at the beginning and end, and single quotes around $somename:

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='$somename'";

I have seen Big Theta, and I'm pretty sure I was taught the difference in school. I had to look it up though. This is what Wikipedia says:

Big O is the most commonly used asymptotic notation for comparing functions, although in many cases Big O may be replaced with Big Theta T for asymptotically tighter bounds.

Source: Big O Notation#Related asymptotic notation

I don't know why people use Big-O when talking formally. Maybe it's because most people are more familiar with Big-O than Big-Theta? I had forgotten that Big-Theta even existed until you reminded me. Although now that my memory is refreshed, I may end up using it in conversation. :)

Try run

git reset --keep HEAD@{1}

$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');

Your code has two problems:

1. The selector .IsBestAnswe does not match what you thought
2. It's addClass(), not addclass().

Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer') part to add only:

$('.IsBestAnswer').addClass('bestanswer');

You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer vs. bestanswer).

Now in c++11 we have

#include <string>
string s = std::to_string(123);

Link to reference: http://en.cppreference.com/w/cpp/string/basic_string/to_string

This isn't possible with ruby currently. You can't pass 'empty' attributes to methods. The closest you can get is to pass nil:

ldap_get(base_dn, filter, nil, X)

However, this will set the scope to nil, not LDAP::LDAP_SCOPE_SUBTREE.

What you can do is set the default value within your method:

def ldap_get(base_dn, filter, scope = nil, attrs = nil)
  scope ||= LDAP::LDAP_SCOPE_SUBTREE
  ... do something ...
end

Now if you call the method as above, the behaviour will be as you expect.

with refresh table or close and open sql server this work

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

Here is good Demo in Fiddle how to use shared service in directive and other controllers through $scope.$on

HTML

<div ng-controller="ControllerZero">
    <input ng-model="message" >
    <button ng-click="handleClick(message);">BROADCAST</button>
</div>

<div ng-controller="ControllerOne">
    <input ng-model="message" >
</div>

<div ng-controller="ControllerTwo">
    <input ng-model="message" >
</div>

<my-component ng-model="message"></my-component>

JS

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

myModule.factory('mySharedService', function($rootScope) {
    var sharedService = {};

    sharedService.message = '';

    sharedService.prepForBroadcast = function(msg) {
        this.message = msg;
        this.broadcastItem();
    };

    sharedService.broadcastItem = function() {
        $rootScope.$broadcast('handleBroadcast');
    };

    return sharedService;
});

By the same way we can use shared service in directive. We can implement controller section into directive and use $scope.$on

myModule.directive('myComponent', function(mySharedService) {
    return {
        restrict: 'E',
        controller: function($scope, $attrs, mySharedService) {
            $scope.$on('handleBroadcast', function() {
                $scope.message = 'Directive: ' + mySharedService.message;
            });
        },
        replace: true,
        template: '<input>'
    };
});

And here three our controllers where ControllerZero used as trigger to invoke prepForBroadcast

function ControllerZero($scope, sharedService) {
    $scope.handleClick = function(msg) {
        sharedService.prepForBroadcast(msg);
    };

    $scope.$on('handleBroadcast', function() {
        $scope.message = sharedService.message;
    });
}

function ControllerOne($scope, sharedService) {
    $scope.$on('handleBroadcast', function() {
        $scope.message = 'ONE: ' + sharedService.message;
    });
}

function ControllerTwo($scope, sharedService) {
    $scope.$on('handleBroadcast', function() {
        $scope.message = 'TWO: ' + sharedService.message;
    });
}

The ControllerOne and ControllerTwo listen message change by using $scope.$on handler.

Note the url in DocumentCompleted can be different than navigating url due to server transfer or url normalization (e.g. you navigate to www.microsoft.com and got http://www.microsoft.com in documentcomplete)

In pages with no frames, this event fires one time after loading is complete. In pages with multiple frames, this event fires for each navigating frame (note navigation is supported inside a frame, for instance clicking a link in a frame could navigate the frame to another page). The highest level navigating frame, which may or may not be the top level browser, fires the final DocumentComplete event.

In native code you would compare the sender of the DocumentComplete event to determine if the event is the final event in the navigation or not. However in Windows Forms the sender parameter is not wrapped by WebBrowserDocumentCompletedEventArgs. You can either sink the native event to get the parameter's value, or check the readystate property of the browser or frame documents in the DocumentCompleted event handler to see if all frames are in the ready state.

There is a prolblem with the readystate method as if a download manager is present and the navigation is to a downloadable file, the navigation could be cancelled by the download manager and the readystate won't become complete.

Create a global variable in and apply the value

<script>
       var isPostBack = <%=Convert.ToString(Page.IsPostBack).ToLower()%>;
</script>

Then you can reference it from elsewhere

Sending and receiving data in JSON format using POST method

// Sending and receiving data in JSON format using POST method
//
var xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
var data = JSON.stringify({"email": "[email protected]", "password": "101010"});
xhr.send(data);

Sending and receiving data in JSON format using GET method

// Sending a receiving data in JSON format using GET method
//      
var xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email": "[email protected]", "password": "101010"}));
xhr.open("GET", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
xhr.send();

Handling data in JSON format on the server-side using PHP

<?php
// Handling data in JSON format on the server-side using PHP
//
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);
?>

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

Better use $_SERVER['REQUEST_METHOD']:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // …
}

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):

# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]

# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True

M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)

# This are all true    
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Enjoy,

If you really need to use sys.path.insert, consider leaving sys.path[0] as it is:

sys.path.insert(1, path_to_dev_pyworkbooks)

This could be important since 3rd party code may rely on sys.path documentation conformance:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter.

There is, however, no guarantee that the output of SDTOUT and STDERR are interweaved line-by-line in timely order, using the POSIX redirect merge syntax.

If an application uses buffered output, it may happen that the text of one stream is inserted in the other at a buffer boundary, which may appear in the middle of a text line.

A dedicated console output logger (I.e. the "StdOut/StdErr Logger" by 'LoRd MuldeR') may be more reliable for such a task.

See: MuldeR's OpenSource Projects

Another useful time to include @ is when you use FOR in the command line. For example:

FOR %F IN (*.*) DO ECHO %F

Previous line show for every file: the command prompt, the ECHO command, and the result of ECHO command. This way:

FOR %F IN (*.*) DO @ECHO %F

Just the result of ECHO command is shown.

I read an article a while ago that talked about locking down every class as much as possible. Make everything final and private unless you have an immediate need to expose some data or functionality to the outside world. It's always easy to expand the scope to be more permissible later on, but not the other way around. First consider making as many things as possible final which will make choosing between private and protected much easier.

1. Make all classes final unless you need to subclass them right away.
2. Make all methods final unless you need to subclass and override them right away.
3. Make all method parameters final unless you need to change them within the body of the method, which is kinda awkward most of the times anyways.

Now if you're left with a final class, then make everything private unless something is absolutely needed by the world - make that public.

If you're left with a class that does have subclass(es), then carefully examine every property and method. First consider if you even want to expose that property/method to subclasses. If you do, then consider whether a subclass can wreak havoc on your object if it messed up the property value or method implementation in the process of overriding. If it's possible, and you want to protect your class' property/method even from subclasses (sounds ironic, I know), then make it private. Otherwise make it protected.

Disclaimer: I don't program much in Java :)

Thanks again to everyone for all the great feedback!

if you happened on CentOS?

You should try to this.

$ service network restart

or

reboot your server.

use window.open("file2.html"); to open on new window,

or use window.location.href = "file2.html" to open on same window.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

You may want to check out the mySQL docs in regard to the date functions. http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html

There is a YEAR() function just as there is a MONTH() function. If you're doing a comparison though is there a reason to chop up the date? Are you truly interested in ignoring day based differences and if so is this how you want to do it?

You need to use == or === for comparison. = assigns a new value.

Besides that, using == is pointless when dealing with booleans only. Just use if(foo) instead of if(foo == true).

string varString = "15";
int i = int.Parse(varString);

or

int varI;
string varString = "15";
int.TryParse(varString, out varI);

int.TryParse is safer since if you put something else in varString (for example "fsfdsfs") you would get an exception. By using int.TryParse when string can't be converted into int it will return 0.

Use:

((Long) userService.getAttendanceList(currentUser)).intValue();

instead.

The .intValue() method is defined in class Number, which Long extends.

Here is the solution:

use Illuminate\Support\Facades\Hash;    
$password = request('password'); // get the value of password field
$hashed = Hash::make($password); // encrypt the password

N.B: Use 1st line code at the very beginning in your controller. Last but not the least, use the rest two lines of code inside the function of your controller where you want to manipulate with data after the from is submitted. Happy coding :)

There seems no way to have google maps api key free without credit card. To test the functionality of google map you can use it while leaving the api key field "EMPTY". It will show a message saying "For Development Purpose Only". And that way you can test google map functionality without putting billing information for google map api key.

You have to use sizeof() function.

Code Snippet:

#include<bits/stdc++.h>
using namespace std;

int main()
{
      ios::sync_with_stdio(false);

      int arr[] ={5, 3, 6, 7};

      int size = sizeof(arr) / sizeof(arr[0]);
      cout<<size<<endl;

      return 0;
}

You don't need to install curl to download the file into Docker container, use ADD command, e.g.

ADD https://raw.githubusercontent.com/Homebrew/install/master/install /tmp
RUN ruby -e /tmp/install

^{Note: Add above lines to your Dockerfile file.}

Another example which installs Azure CLI:

ADD https://aka.ms/InstallAzureCLIDeb /tmp
RUN bash /tmp/InstallAzureCLIDeb

If you want to initialize the array to -1 then you can use the following,

memset(array, -1, sizeof(array[0][0]) * row * count)

But this will work 0 and -1 only

Add the class constraint as the first constraint to your generic type.

static T FindThing<T>(IList collection, int id) where T : class, IThing, new()

It's an if statement all on one line.

So

var x=1;
(x == 1) ? y="true" : y="false";
alert(y);

The expression to be evaluated is in the ( )

If it matches true, execute the code after the ?

If it matches false, execute the code after the :

Why not just use key name on dictionary, C# has this:

 Dictionary<string, string> dict = new Dictionary<string, string>();
 dict.Add("UserID", "test");
 string userIDFromDictionaryByKey = dict["UserID"];

If you look at the tip suggestion:

Apart from the obvious die() and exit(), this also works:

<?php
echo "start";
__halt_compiler();
echo "you should not see this";
?>

You're looking for the continue; statement.

you have an extra "}" in each object, you may write the json string like this:

public class ShowActivity {   
    private final static String  jString = "{" 
    + "    \"geodata\": [" 
    + "        {" 
    + "                \"id\": \"1\"," 
    + "                \"name\": \"Julie Sherman\","                  
    + "                \"gender\" : \"female\"," 
    + "                \"latitude\" : \"37.33774833333334\"," 
    + "                \"longitude\" : \"-121.88670166666667\""            
    + "                }" 
    + "        }," 
    + "        {" 
    + "                \"id\": \"2\","

    + "                \"latitude\" : \"37.336453\"," 
    + "                \"longitude\" : \"-121.884985\""            
    + "                }" 
    + "        }" 
    + "    ]" 
    + "}"; 
}

The instanceof operator does not need explicit null checks, as it does not throw a NullPointerException if the operand is null.

At run time, the result of the instanceof operator is true if the value of the relational expression is not null and the reference could be cast to the reference type without raising a class cast exception.

If the operand is null, the instanceof operator returns false and hence, explicit null checks are not required.

Consider the below example,

public static void main(String[] args) {
         if(lista != null && lista instanceof ArrayList) {                     //Violation
                System.out.println("In if block");
         }
         else {
                System.out.println("In else block");
         }
}

The correct usage of instanceof is as shown below,

public static void main(String[] args) {
      
         if(lista instanceof ArrayList){                     //Correct way
                  System.out.println("In if block");
         }
            else {
                 System.out.println("In else block");
         }  
}

String fileContents = new File('/path/to/file').text

If you need to specify the character encoding, use the following instead:

String fileContents = new File('/path/to/file').getText('UTF-8')

Answers suggesting to disable CURLOPT_SSL_VERIFYPEER should not be accepted. The question is "Why doesn't it work with cURL", and as correctly pointed out by Martijn Hols, it is dangerous.

The error is probably caused by not having an up-to-date bundle of CA root certificates. This is typically a text file with a bunch of cryptographic signatures that curl uses to verify a host’s SSL certificate.

You need to make sure that your installation of PHP has one of these files, and that it’s up to date (otherwise download one here: http://curl.haxx.se/docs/caextract.html).

Then set in php.ini:

curl.cainfo = <absolute_path_to> cacert.pem

If you are setting it at runtime, use:

curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/cacert.pem");

You can use Console.WriteLine() to write out any native type. To see the output you must write console application (like in Java), then the output will be displayed in the Command Prompt, or if you are developing a windows GUI application, in Visual Studio you must turn on "Output" panel (under View) to see the commands output.

I use the following in a console app, running as a service, to get directory info from the App.Settings file. Number of days to keep the files is also configurable, multiplied by -1 for use in the AddDays() method of DateTime.Now.

static void CleanBackupFiles()
        {
            string gstrUncFolder = ConfigurationManager.AppSettings["DropFolderUNC"] + "";
            int iDelAge = Convert.ToInt32(ConfigurationManager.AppSettings["NumDaysToKeepFiles"]) * -1;
            string backupdir = string.Concat(@"\", "Backup", @"\");

            string[] files = Directory.GetFiles(string.Concat(gstrUncFolder, backupdir));


            foreach (string file in files)
            {
                FileInfo fi = new FileInfo(file);
                if (fi.CreationTime < DateTime.Now.AddDays(iDelAge))
                {
                    fi.Delete();
                }
            }

        }

I'm not sure if this would work (data could be omitted), but this may work:

*dataframe name*.tails(1)

and then using this, you could find the number of rows by running the code snippet and looking at the row number that was given to you.

If the order of the execution is not important and you need both some javascript AND some codebehind to be fired on an asp element, heres what you can do.

What you can take away from my example: I have a div covering the ASP control that I want both javascript and codebehind to be ran from. The div's onClick method AND the calendar's OnSelectionChanged event both get fired this way.

In this example, i am using an ASP Calendar control, and im controlling it from both javascript and codebehind:

Front end code:

        <div onclick="showHideModal();">

I found this snippet here. The idea is to go up the DOM node hierarchy until a __vue__ property is found.

function getVueFromElement(el) {
  while (el) {
    if (el.__vue__) {
      return el.__vue__
    } else {
      el = el.parentNode
    }
  }
}

In Chrome:

Search till the seconds for the timestamp column in postgress

select * from "TableName" e
    where timestamp >= '2020-08-08T13:00:00' and timestamp < '2020-08-08T17:00:00';

Below method uploads file in a particular folder in a bucket and return the generated url of the file uploaded.

private String uploadFileToS3Bucket(final String bucketName, final File file) {
    final String uniqueFileName = uploadFolder + "/" + file.getName();
    LOGGER.info("Uploading file with name= " + uniqueFileName);
    final PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, uniqueFileName, file);
    amazonS3.putObject(putObjectRequest);
    return ((AmazonS3Client) amazonS3).getResourceUrl(bucketName, uniqueFileName);
}

I've found that replacing the first part of the URL with IP address numbers instead of words worked for me.

For example use:

http://111.11.11.111/svn/Directory

instead of:

http://www.url.com/svn/Directory

My understanding is that the SQL standard calls for case-insensitivity. I don't believe any databases follow the standard completely, though.

MySQL has a configuration setting as part of its "strict mode" (a grab bag of several settings that make MySQL more standards-compliant) for case sensitive or insensitive table names. Regardless of this setting, column names are still case-insensitive, although I think it affects how the column-names are displayed. I believe this setting is instance-wide, across all databases within the RDBMS instance, although I'm researching today to confirm this (and hoping the answer is no).

I like how Oracle handles this far better. In straight SQL, identifiers like table and column names are case insensitive. However, if for some reason you really desire to get explicit casing, you can enclose the identifier in double-quotes (which are quite different in Oracle SQL from the single-quotes used to enclose string data). So:

SELECT fieldName
FROM tableName;

will query fieldname from tablename, but

SELECT "fieldName"
FROM "tableName";

will query fieldName from tableName.

I'm pretty sure you could even use this mechanism to insert spaces or other non-standard characters into an identifier.

In this situation if for some reason you found explicitly-cased table and column names desirable it was available to you, but it was still something I would highly caution against.

My convention when I used Oracle on a daily basis was that in code I would put all Oracle SQL keywords in uppercase and all identifiers in lowercase. In documentation I would put all table and column names in uppercase. It was very convenient and readable to be able to do this (although sometimes a pain to type so many capitals in code -- I'm sure I could've found an editor feature to help, here).

In my opinion MySQL is particularly bad for differing about this on different platforms. We need to be able to dump databases on Windows and load them into UNIX, and doing so is a disaster if the installer on Windows forgot to put the RDBMS into case-sensitive mode. (To be fair, part of the reason this is a disaster is our coders made the bad decision, long ago, to rely on the case-sensitivity of MySQL on UNIX.) The people who wrote the Windows MySQL installer made it really convenient and Windows-like, and it was great to move toward giving people a checkbox to say "Would you like to turn on strict mode and make MySQL more standards-compliant?" But it is very convenient for MySQL to differ so signficantly from the standard, and then make matters worse by turning around and differing from its own de facto standard on different platforms. I'm sure that on differing Linux distributions this may be further compounded, as packagers for different distros probably have at times incorporated their own preferred MySQL configuration settings.

Here's another SO question that gets into discussing if case-sensitivity is desirable in an RDBMS.

Simply use String.ElementAt(). It's quite similar to java's String.charAt(). Have fun coding!

ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;

SQLAlchemy's ORM is meant to be used together with the SQL layer, not hide it. But you do have to keep one or two things in mind when using the ORM and plain SQL in the same transaction. Basically, from one side, ORM data modifications will only hit the database when you flush the changes from your session. From the other side, SQL data manipulation statements don't affect the objects that are in your session.

So if you say

for c in session.query(Stuff).all():
    c.foo = c.foo+1
session.commit()

it will do what it says, go fetch all the objects from the database, modify all the objects and then when it's time to flush the changes to the database, update the rows one by one.

Instead you should do this:

session.execute(update(stuff_table, values={stuff_table.c.foo: stuff_table.c.foo + 1}))
session.commit()

This will execute as one query as you would expect, and because at least the default session configuration expires all data in the session on commit you don't have any stale data issues.

In the almost-released 0.5 series you could also use this method for updating:

session.query(Stuff).update({Stuff.foo: Stuff.foo + 1})
session.commit()

That will basically run the same SQL statement as the previous snippet, but also select the changed rows and expire any stale data in the session. If you know you aren't using any session data after the update you could also add synchronize_session=False to the update statement and get rid of that select.

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"
        android:orderInCategory="100"
        android:showAsAction="always"/> 
</menu>

My workaround for this issue was to set display: inline to the image element. With this, your image and text will be aligned to the right if you set text-align: right from a parent container.

Use jquery-dateFormat. It will solve your problem.

You need to include the jquery.dateFormat in your html file.

<script>
var date = $('#scheduleDate').val();
document.write($.format.date(date, "dd,MM,yyyy"));

var dateTypeVar = $('#scheduleDate').datepicker('getDate');
document.write($.format.date(dateTypeVar, "dd-MM-yy"));
</script>

append a text node as follows

var td1 = document.getElementById('td1');
var text = document.createTextNode("some text");
td1.appendChild(text);

Use splice if you already know the index of the element you want to delete.

Grep works if you are searching.

If you need to do a lot of these, you will get much better performance if you keep your array in sorted order, since you can then do binary search to find the necessary index.

If it makes sense in your context, you may want to consider using a "magic value" for deleted records, rather then deleting them, to save on data movement -- set deleted elements to undef, for example. Naturally, this has its own issues (if you need to know the number of "live" elements, you need to keep track of it separately, etc), but may be worth the trouble depending on your application.

Edit Actually now that I take a second look -- don't use the grep code above. It would be more efficient to find the index of the element you want to delete, then use splice to delete it (the code you have accumulates all the non-matching results..)

my $index = 0;
$index++ until $arr[$index] eq 'foo';
splice(@arr, $index, 1);

That will delete the first occurrence. Deleting all occurrences is very similar, except you will want to get all indexes in one pass:

my @del_indexes = grep { $arr[$_] eq 'foo' } 0..$#arr;

The rest is left as an excercise for the reader -- remember that the array changes as you splice it!

Edit2 John Siracusa correctly pointed out I had a bug in my example.. fixed, sorry about that.

There are 3 things I can think of off the top of my head:

1. Just used named urls, it's more robust and maintainable anyway

2. Try using django.core.urlresolvers.reverse at the command line for a (possibly) better error

   >>> from django.core.urlresolvers import reverse
   >>> reverse('products.views.filter_by_led')
   

3. Check to see if you have more than one url that points to that view

What I tend to do, and I believe this is what Google intended for developers to do too, is to still get the extras from an Intent in an Activity and then pass any extra data to fragments by instantiating them with arguments.

There's actually an example on the Android dev blog that illustrates this concept, and you'll see this in several of the API demos too. Although this specific example is given for API 3.0+ fragments, the same flow applies when using FragmentActivity and Fragment from the support library.

You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment:

public static class DetailsActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // (omitted some other stuff)

        if (savedInstanceState == null) {
            // During initial setup, plug in the details fragment.
            DetailsFragment details = new DetailsFragment();
            details.setArguments(getIntent().getExtras());
            getSupportFragmentManager().beginTransaction().add(
                    android.R.id.content, details).commit();
        }
    }
}

In stead of directly invoking the constructor, it's probably easier to use a static method that plugs the arguments into the fragment for you. Such a method is often called newInstance in the examples given by Google. There actually is a newInstance method in DetailsFragment, so I'm unsure why it isn't used in the snippet above...

Anyways, all extras provided as argument upon creating the fragment, will be available by calling getArguments(). Since this returns a Bundle, its usage is similar to that of the extras in an Activity.

public static class DetailsFragment extends Fragment {
    /**
     * Create a new instance of DetailsFragment, initialized to
     * show the text at 'index'.
     */
    public static DetailsFragment newInstance(int index) {
        DetailsFragment f = new DetailsFragment();

        // Supply index input as an argument.
        Bundle args = new Bundle();
        args.putInt("index", index);
        f.setArguments(args);

        return f;
    }

    public int getShownIndex() {
        return getArguments().getInt("index", 0);
    }

    // (other stuff omitted)

}

Use EntityScanner if you can bear external dependency.It will inject your all entity classes seamlessly even from multiple packages. Just add following line after configuration setup.

Configuration configuration = new Configuration().configure();    
EntityScanner.scanPackages("com.fz.epms.db.model.entity").addTo(configuration);
// And following depencency if you are using Maven
<dependency>
        <groupId>com.github.v-ladynev</groupId>
        <artifactId>fluent-hibernate-core</artifactId>
        <version>0.3.1</version>
</dependency>

This way you don't need to declare all entities in hibernate mapping file.

A better approach to creating constants in Python is to take inspiration from the excellent attrs library, which helps Python programmers create classes without boilerplate. The short-con package does the same for constants by providing a convenience wrapper around attr.make_class. [Disclaimer: I am the author of short-con.]

Values can be declared explicitly via either a dict or kwargs: These examples do the same thing. The constants() function supports all features of the library, and cons() is a helper for simple kwarg-based usage.

from short_con import constants, cons

Pieces = constants('Pieces', dict(king = 0, queen = 9, rook = 5, bishop = 3, knight = 3, pawn = 1))
Pieces = cons('Pieces', king = 0, queen = 9, rook = 5, bishop = 3, knight = 3, pawn = 1)

For situations when the values are the same as (or can be derived from) the attribute names, usage is even more compact. Just supply names as a space-delimited string, list, or tuple.

NAMES = 'KING QUEEN ROOK BISHOP KNIGHT PAWN'
xs = NAMES.split()

Pieces = constants('Pieces', NAMES)      # All of these do the same thing.
Pieces = constants('Pieces', xs)
Pieces = constants('Pieces', tuple(xs))

The name-based usages support a few stylistic conventions: uppercase or lowercase attribute names, along with enum-style values.

The underlying values are directly accessible, unlike constants created by the built-in enum library:

Pieces.QUEEN        # short-con usage
Pieces.QUEEN.value  # enum library usage

And the object is directly iterable and convertible to other collections:

for name, value in Pieces:
    print(name, value)

d = dict(Pieces)
tups = list(Pieces)

This is what worked for me perfectly:-

// slide the view from its current position to below itself
public void slideUp(final View view, final View llDomestic){

    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",0f);
    animation.setDuration(100);
    llDomestic.setVisibility(View.GONE);
    animation.start();

}

// slide the view from below itself to the current position
public void slideDown(View view,View llDomestic){
    llDomestic.setVisibility(View.VISIBLE);
    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",   0f);
    animation.setDuration(100);
    animation.start();
}

llDomestic : The view which you want to hide. view: The view which you want to move down or up.

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

The pickle (and gzip if the file is compressed) module need to be used

This is a C# Version. It's based on the idea of sort the array.

public int solution(int[] A)
 {
    // write your code in C# 6.0 with .NET 4.5 (Mono)
    Array.Sort(A);
    var max = A.Max();
    if(max < 0)
        return 1;
    else
        for (int i = 1; i < max; i++)
        {
            if(!A.Contains(i)) {
                return i;
            }
        }
    return max + 1;
}

Prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:

<?php

    $dbh = new PDO("mysql:$connstr",  $user, $password);

    $dbh -> exec("set names utf8");

?>

from numpy.lib.scimath import logn
from math import e

#using: x - var
logn(e, x)

I use DbVisualizer a lot for H2-db administration.

All you need is to create two layouts:

1. an empty layout

2. main layout

Then write the code below in _viewStart file:

@{
   if (Request.IsAjaxRequest())
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
   }
   else
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
   }
 }

of course, maybe it is not the best solution

Nope. You could have a function to make it more concise each place you use it, but in the end, the work done would be the same (plus the overhead of the function call, until/unless HotSpot moved it inline — to help it with that, make the functon static final).

I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..

Opening A Seperate File:

ChDir "[Path here]"                          'get into the right folder here
Workbooks.Open Filename:= "[Path here]"      'include the filename in this path

'copy data into current workbook or whatever you want here

ActiveWindow.Close                          'closes out the file

Opening A File With Specified Date If It Exists:

I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.

Some common error checking statements:

On Error Resume Next   'if error occurs continues on to the next line (ignores it)

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

Or (better option):

if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?

you would most likely want to use the GoTo ErrorHandler shown below to achieve this

On Error GoTo ErrorHandler:

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

ErrorHandler:
'Display error message or any code you want to run on error here

Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm

Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/

Hope this helps!

Example on how to ensure error code doesn't run EVERYtime:

if you debug through the code without the Exit Sub BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.

  Sub Macro

    On Error GoTo ErrorHandler:

    ChDir "[Path here]"                         
    Workbooks.Open Filename:= "[Path here]"      'try to open file here

    Exit Sub      'Code will exit BEFORE ErrorHandler if everything goes smoothly
                  'Otherwise, on error, ErrorHandler will be run

    ErrorHandler:
    'Display error message or any code you want to run on error here

  End Sub

Also, look at this other question in you need more reference to how this works: goto block not working VBA

Since 2019, Array.prototype.flatMap is good option.

options.flatMap(o => o.assigned ? [o.name] : []);

From the MDN page linked above:

flatMap can be used as a way to add and remove items (modify the number of items) during a map. In other words, it allows you to map many items to many items (by handling each input item separately), rather than always one-to-one. In this sense, it works like the opposite of filter. Simply return a 1-element array to keep the item, a multiple-element array to add items, or a 0-element array to remove the item.

Swift 3.0 version

let arr = yourString.components(separatedBy: "/")
let month = arr[0]

Normally, when the user tabs from field to field in a form (in a browser that allows tabbing, not all browsers do) the order is the order the fields appear in the HTML code.

However, sometimes you want the tab order to flow a little differently. In that case, you can number the fields using TABINDEX. The tabs then flow in order from lowest TABINDEX to highest.

More info on this can be found here w3

another good illustration can be found here

malloc() (and its friends free() and realloc()) is the way to do this in C.

Try adding a view users/show.json.erb This should be rendered when you make a request for the JSON format, and you get the added benefit of it being rendered by erb too, so your file could look something like this

{
    "first_name": "<%= @user.first_name.to_json %>",
    "last_name": "<%= @user.last_name.to_json %>"
}

From the MSDN library:

The First<TSource>(IEnumerable<TSource>) method throws an exception if source contains no elements. To instead return a default value when the source sequence is empty, use the FirstOrDefault method.

If you switch from Web to Express you will no longer be able to use the SQL Server Agent service so you need to set up a different scheduler for maintenance and backups.

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

Maybe not a direct answer to the question, but a recent addition to the official documentation describes how jQuery can be used to disable transitions entirely just by:

$.support.transition = false

Setting the .collapsing CSS transitions to none as mentioned in the accepted answer removed the animation. But this — in Firefox and Chromium for me — creates an unwanted visual issue on collapse of the navbar.

For instance, visit the Bootstrap navbar example and add the CSS from the accepted answer:

.collapsing {
     -webkit-transition: none;
     transition: none;
}

What I currently see is when the navbar collapses, the bottom border of the navbar momentarily becomes two pixels instead of one, then disconcertingly jumps back to one. Using jQuery, this artifact doesn't appear.

Here is a working version using v3 of docker-compose.yml. The key is the volumes directive:

mysql:
  image: mysql:5.6
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: root
    MYSQL_USER: theusername
    MYSQL_PASSWORD: thepw
    MYSQL_DATABASE: mydb
  volumes:
    - ./data:/docker-entrypoint-initdb.d

In the directory that I have my docker-compose.yml I have a data dir that contains .sql dump files. This is nice because you can have a .sql dump file per table.

I simply run docker-compose up and I'm good to go. Data automatically persists between stops. If you want remove the data and "suck in" new .sql files run docker-compose down then docker-compose up.

If anyone knows how to get the mysql docker to re-process files in /docker-entrypoint-initdb.d without removing the volume, please leave a comment and I will update this answer.

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

First create a class like:

public class Encryption
    { 
        public static string Encrypt(string clearText)
        {
            string EncryptionKey = "MAKV2SPBNI99212";
            byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
            using (Aes encryptor = Aes.Create())
            {
                Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
                encryptor.Key = pdb.GetBytes(32);
                encryptor.IV = pdb.GetBytes(16);
                using (MemoryStream ms = new MemoryStream())
                {
                    using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
                    {
                        cs.Write(clearBytes, 0, clearBytes.Length);
                        cs.Close();
                    }
                    clearText = Convert.ToBase64String(ms.ToArray());
                }
            }
            return clearText;
        }

        public static string Decrypt(string cipherText)
        {
            string EncryptionKey = "MAKV2SPBNI99212";
            byte[] cipherBytes = Convert.FromBase64String(cipherText);
            using (Aes encryptor = Aes.Create())
            {
                Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
                encryptor.Key = pdb.GetBytes(32);
                encryptor.IV = pdb.GetBytes(16);
                using (MemoryStream ms = new MemoryStream())
                {
                    using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateDecryptor(), CryptoStreamMode.Write))
                    {
                        cs.Write(cipherBytes, 0, cipherBytes.Length);
                        cs.Close();
                    }
                    cipherText = Encoding.Unicode.GetString(ms.ToArray());
                }
            }
            return cipherText;
        }
    }

**In Controller **

add reference for this encryption class:

using testdemo.Models

public ActionResult Index() {
            return View();
        }
        [HttpPost]
        public ActionResult Index(string text)
        {
            if (Request["txtEncrypt"] != null)
            {
                string getEncryptionCode = Request["txtEncrypt"];
                string DecryptCode = Encryption.Decrypt(HttpUtility.UrlDecode(getEncryptionCode));
                ViewBag.GetDecryptCode = DecryptCode;
                return View();
            }
            else {
                string getDecryptCode = Request["txtDecrypt"];
                string EncryptionCode = HttpUtility.UrlEncode(Encryption.Encrypt(getDecryptCode));
                ViewBag.GetEncryptionCode = EncryptionCode;
                return View();
            }

        }

In View

<h2>Decryption Code</h2>
@using (Html.BeginForm())
{
    <table class="table-bordered table">
        <tr>
            <th>Encryption Code</th>
            <td><input type="text" id="txtEncrypt" name="txtEncrypt" placeholder="Enter Encryption Code" /></td>
        </tr>
        <tr>

Just set the position of the div and you may have to set the z-index.

ex.

div#map-div {
    position: absolute;
    left: 10px;
    top: 10px;
}
div#cover-div {
    position:absolute;
    left:10px;
    top: 10px;
    z-index:3;
}

You can try with textContent.

var productId = val[key].textContent;

This is what I tried for a right outer join [as per my requirement]:

m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink, 
            by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"), 
            by.y=c("company_permalink"), all.y=TRUE)

This worked.

I was searching an answer for this same question and found ENTRYPOINT in Dockerfile solution for me.

Dockerfile

...
ENTRYPOINT /my-script.sh ; /my-script2.sh ; /bin/bash

Now the scripts are executed when I start the container and I get the bash prompt after the scripts has been executed.

Please be aware that the examples for icon file path tend to assume that main.js is under the base directory. If the file is not in the base directory of the app, the path specification must account for that fact.

For example, if the main.js is under the src/ subdirectory, and the icon is under assets/icons/, this icon path specification will work:

icon: __dirname + "../assets/icons/icon.png"

I have searched the web for an answer regarding MAC OS, so .. the solution is

cd /Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents/MacOS/

VBoxManage internalcommands sethduuid "full/path/to/vdi"

use request scope @Scope("request") to get bean for each request, or @Scope("session") to get bean for each session 'user'

You can use the fmt= parameter and fill the value based on the following table :

http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs

Ex : your URL would become :

http://www.youtube.com/embed/FqRgAs0SOpU?fmt=35

There is an important detail that has been omitted in the answer above.

MySQL imposes a limit of 65,535 bytes for the max size of each row. The size of a VARCHAR column is counted towards the maximum row size, while TEXT columns are assumed to be storing their data by reference so they only need 9-12 bytes. That means even if the "theoretical" max size of your VARCHAR field is 65,535 characters you won't be able to achieve that if you have more than one column in your table.

Also note that the actual number of bytes required by a VARCHAR field is dependent on the encoding of the column (and the content). MySQL counts the maximum possible bytes used toward the max row size, so if you use a multibyte encoding like utf8mb4 (which you almost certainly should) it will use up even more of your maximum row size.

Correction: Regardless of how MySQL computes the max row size, whether or not the VARCHAR/TEXT field data is ACTUALLY stored in the row or stored by reference depends on your underlying storage engine. For InnoDB the row format affects this behavior. (Thanks Bill-Karwin)

Reasons to use TEXT:

• If you want to store a paragraph or more of text
• If you don't need to index the column
• If you have reached the row size limit for your table

Reasons to use VARCHAR:

• If you want to store a few words or a sentence
• If you want to index the (entire) column
• If you want to use the column with foreign-key constraints

That's the correct way. Calendars work the same way. The best I could offer you (based on your example) is this:

boolean isWithinRange(Date testDate) {
    return testDate.getTime() >= startDate.getTime() &&
             testDate.getTime() <= endDate.getTime();
}

Date.getTime() returns the number of milliseconds since 1/1/1970 00:00:00 GMT, and is a long so it's easily comparable.

Since JsonSerializer is deprecated in .Net 4.0+ I used http://www.newtonsoft.com/json to solve this issue.

NuGet- > Install-Package Newtonsoft.Json

var string  = "Hello World";
console.log(charAt(0));

The charAt(0) is JavaScript method, It will return value based on index, here 0 is the index for first letter.

the below lines would also work

!python script.py

Keep in mind that MySQL has a maximum row size limit

The internal representation of a MySQL table has a maximum row size limit of 65,535 bytes, not counting BLOB and TEXT types. BLOB and TEXT columns only contribute 9 to 12 bytes toward the row size limit because their contents are stored separately from the rest of the row. Read more about Limits on Table Column Count and Row Size.

Maximum size a single column can occupy, is different before and after MySQL 5.0.3

Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.

However, note that the limit is lower if you use a multi-byte character set like utf8 or utf8mb4.

Use TEXT types inorder to overcome row size limit.

The four TEXT types are TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. These correspond to the four BLOB types and have the same maximum lengths and storage requirements.

More details on BLOB and TEXT Types

Even more

Checkout more details on Data Type Storage Requirements which deals with storage requirements for all data types.

you don't need to set the width of header in css, just put the background image as center using this code:

background: url("images/logo.png") no-repeat top center;

or you can just use img tag and put align="center" in the div

Make a 2-dimensional array that corresponds to the cells in your final image, called say heatmap_cells and instantiate it as all zeroes.

Choose two scaling factors that define the difference between each array element in real units, for each dimension, say x_scale and y_scale. Choose these such that all your datapoints will fall within the bounds of the heatmap array.

For each raw datapoint with x_value and y_value:

heatmap_cells[floor(x_value/x_scale),floor(y_value/y_scale)]+=1

Try this :

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

        }

        #btn_i {
            width:125px;
        }
        #formbox {
            width:400px;
            margin:auto 0;
            text-align: center;

This has 2 examples, you can use the one that fits best in your situation.

• use text-align:center on the parent container, or create a container for this.
• if the container has to have a fixed size, use auto left and right margins to center it in the parent container.

note that auto is used with single blocks to center them in the parent space by distrubuting the empty space to the left and right.

IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database.

COPY <all> <the> <things> <last-arg-is-destination>

But here is an important excerpt from the docs:

If you have multiple Dockerfile steps that use different files from your context, COPY them individually, rather than all at once. This ensures that each step’s build cache is only invalidated (forcing the step to be re-run) if the specifically required files change.

https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#add-or-copy

nametext = "Your name is" + name;

I think this should do

Just handle the form submission on the submit event, and return false:

$('#contactForm').submit(function () {
 sendContactForm();
 return false;
});

You don't need any more the onclick event on the submit button:

<input class="submit" type="submit" value="Send" />

Simply add [] to those names like

 <input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
 <input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">

Take that template and then you can add those even using a loop.

Then you can add those dynamically as much as you want, without having to provide an index. PHP will pick them up just like your expected scenario example.

Edit

Sorry I had braces in the wrong place, which would make every new value as a new array element. Use the updated code now and this will give you the following array structure

levels > level (Array)
levels > build_time (Array)

Same index on both sub arrays will give you your pair. For example

echo $levels["level"][5];
echo $levels["build_time"][5];

You can use routerLink in the following manner,

<input type="button" value="Add Bulk Enquiry" [routerLink]="['../addBulkEnquiry']" class="btn">

or use <button [routerLink]="['./url']"> in your case, for more info you could read the entire stacktrace on github https://github.com/angular/angular/issues/9471

the other methods are also correct but they create a dependency on the component file.

Hope your concern is resolved.

The answers from freedompeace, Kiyarash and Sam Vloeberghs:

.rar    application/x-rar-compressed, application/octet-stream
.zip    application/zip, application/octet-stream, application/x-zip-compressed, multipart/x-zip

I would do a check on the file name too. Here is how you could check if the file is a RAR or ZIP file. I tested it by creating a quick command line application.

<?php

if (isRarOrZip($argv[1])) {
    echo 'It is probably a RAR or ZIP file.';
} else {
    echo 'It is probably not a RAR or ZIP file.';
}

function isRarOrZip($file) {
    // get the first 7 bytes
    $bytes = file_get_contents($file, FALSE, NULL, 0, 7);
    $ext = strtolower(substr($file, - 4));

    // RAR magic number: Rar!\x1A\x07\x00
    // http://en.wikipedia.org/wiki/RAR
    if ($ext == '.rar' and bin2hex($bytes) == '526172211a0700') {
        return TRUE;
    }

    // ZIP magic number: none, though PK\003\004, PK\005\006 (empty archive), 
    // or PK\007\008 (spanned archive) are common.
    // http://en.wikipedia.org/wiki/ZIP_(file_format)
    if ($ext == '.zip' and substr($bytes, 0, 2) == 'PK') {
        return TRUE;
    }

    return FALSE;
}

Notice that it still won't be 100% certain, but it is probably good enough.

$ rar.exe l somefile.zip
somefile.zip is not RAR archive

But even WinRAR detects non RAR files as SFX archives:

$ rar.exe l somefile.srr
SFX Volume somefile.srr

You can try this, it works for me.

 <input type="text"  onchange="CheckValidAmount(this.value)" name="amount" required>

 <script type="text/javascript">
    function CheckValidAmount(amount) {          
       var a = /^(?:\d{1,3}(?:,\d{3})*|\d+)(?:\.\d+)?$/;
       if(amount.match(a)){
           alert("matches");
       }else{
        alert("does not match"); 
       }
    }
</script>

/**
 * @param filePath
 * @param fs
 * @return list of absolute file path present in given path
 * @throws FileNotFoundException
 * @throws IOException
 */
public static List<String> getAllFilePath(Path filePath, FileSystem fs) throws FileNotFoundException, IOException {
    List<String> fileList = new ArrayList<String>();
    FileStatus[] fileStatus = fs.listStatus(filePath);
    for (FileStatus fileStat : fileStatus) {
        if (fileStat.isDirectory()) {
            fileList.addAll(getAllFilePath(fileStat.getPath(), fs));
        } else {
            fileList.add(fileStat.getPath().toString());
        }
    }
    return fileList;
}

Quick Example : Suppose you have the following file structure:

a  ->  b
   ->  c  -> d
          -> e 
   ->  d  -> f

Using the code above, you get:

a/b
a/c/d
a/c/e
a/d/f

If you want only the leaf (i.e. fileNames), use the following code in else block :

 ...
    } else {
        String fileName = fileStat.getPath().toString(); 
        fileList.add(fileName.substring(fileName.lastIndexOf("/") + 1));
    }

This will give:

b
d
e
f

I second Dave's idea. I'm not always fond of pivot tables, but in this case they are pretty straightforward to use.

Here are my results:

It was so simple to create it that I have even recorded a macro in case you need to do this with VBA:

Sub Macro2()
'
' Macro2 Macro
'

'
    Range("Table1[[#All],[DATA]]").Select
    ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
        "Table1", Version:=xlPivotTableVersion14).CreatePivotTable TableDestination _
        :="Sheet3!R3C7", TableName:="PivotTable4", DefaultVersion:= _
        xlPivotTableVersion14
    Sheets("Sheet3").Select
    Cells(3, 7).Select
    With ActiveSheet.PivotTables("PivotTable4").PivotFields("DATA")
        .Orientation = xlRowField
        .Position = 1
    End With
    ActiveSheet.PivotTables("PivotTable4").AddDataField ActiveSheet.PivotTables( _
        "PivotTable4").PivotFields("DATA"), "Count of DATA", xlCount
End Sub

If you know you have a number of seconds, you can create a TimeSpan value by calling TimeSpan.FromSeconds:

 TimeSpan ts = TimeSpan.FromSeconds(80);

You can then obtain the number of days, hours, minutes, or seconds. Or use one of the ToString overloads to output it in whatever manner you like.

You can use lftp interactively in a shell script so the password not saved in .bash_history or similar by doing the following:

vi test_script.sh

Add the following to your file:

#!/bin/sh
HOST=<yourhostname>
USER=<someusername>
PASSWD=<yourpasswd>

cd <base directory for your put file>

lftp<<END_SCRIPT
open sftp://$HOST
user $USER $PASSWD
put local-file.name
bye
END_SCRIPT

And write/quit the vi editor after you edit the host, user, pass, and directory for your put file typing :wq .Then make your script executable chmod +x test_script.sh and execute it ./test_script.sh.

From what I can tell, there is no way to natively show just the current branch in Git, so I have been using:

git branch | grep '*'

If you are targeting iOS 8+ you can use the new NSCalendar convenience methods to achieve this in a more terse format.

First create an NSCalendar and use whatever NSDate is required.

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *date = [NSDate date];

You could extract components individually via component:fromDate:

NSInteger year = [calendar component:NSCalendarUnitYear fromDate:date];
NSInteger month = [calendar component:NSCalendarUnitMonth fromDate:date];
NSInteger day = [calendar component:NSCalendarUnitDay fromDate:date];

Or, even more succinctly, use NSInteger pointers via getEra:year:month:day:fromDate:

NSInteger year, month, day;
[calendar getEra:nil year:&year month:&month day:&day fromDate:date];

For more information and examples check out NSDate Manipulation Made Easy in iOS 8. Disclaimer, I wrote the post.

If key is present table.put(key, val) will just overwrite the value else it'll create a new entry. Poof! and you are done. :)

you can get the value from a map by using key is table.get(key); That's about it

Actually a more refined solution is use the build-in function sumif, this function does exactly what you need, will only sum those expenses of a specified month.

example

=SUMIF(A2:A100,"=January",B2:B100)

... Could not load file or assembly 'X' or one of its dependencies ...

Most likely it fails to load another dependency.

you could try to check the dependencies with a dependency walker.

I.e: https://www.dependencywalker.com/

Also check your build configuration (x86 / 64)

Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.

See here: Detected DLLs that are from the internet and "blocked" by CASPOL

Code to avoid returning an empty string ( when input is like "00000").

string myStr = "00012345";
myStr = myStr.TrimStart('0');
myStr = myStr.Length > 0 ? myStr : "0";

I have been struggling with VS2010/DNFW 4.5 integration and have finally got this working. Starting in VS 2008, a cache of assemblies was introduced that is used by Visual Studio called the "Referenced Assemblies". This file cache for VS 2010 is located at \Reference Assemblies\Microsoft\Framework.NetFramework\v4.0. Visual Studio loads framework assemblies from this location instead of from the framework installation directory. When Microsoft says that VS 2010 does not support DNFW 4.5 what they mean is that this directory does not get updated when DNFW 4.5 is installed. Once you have replace the files in this location with the updated DNFW 4.5 files, you will find that VS 2010 will happily function with DNFW 4.5.

Why not just:

$('#b').click(function () {
    var val = $(this).val(); 
})

Or if you don't click it (and I guess you won't) and you will use submit button, you can use prev() function either.

If you are using Databricks and can fit all the data into RAM on one worker (and thus can use .coalesce(1)), you can use dbfs to find and move the resulting CSV file:

val fileprefix= "/mnt/aws/path/file-prefix"

dataset

If your file does not fit into RAM on the worker, you may want to consider chaotic3quilibrium's suggestion to use FileUtils.copyMerge(). I have not done this, and don't yet know if is possible or not, e.g., on S3.

This answer is built on previous answers to this question as well as my own tests of the provided code snippet. I originally posted it to Databricks and am republishing it here.

The best documentation for dbfs's rm's recursive option I have found is on a Databricks forum.

Note that textarea[readonly="readonly"] works if you set readonly="readonly" in HTML but it does NOT work if you set the readOnly-attribute to true or "readonly" via JavaScript.

For the CSS selector to work if you set readOnly with JavaScript you have to use the selector textarea[readonly].

Same behavior in Firefox 14 and Chrome 20.

To be on the safe side, i use both selectors.

textarea[readonly="readonly"], textarea[readonly] {
...
}

I'm not sure if this is frowned upon or not, but this is how I do it...

Step 1 - I usually have a class that contains methods and variables that I want to access globally. In this example I'll call it the "App" class. Create a static Activity variable inside the class for each activity that your app has. Then create a static method called "close" that will run the finish() method on each of those Activity variables if they are NOT null. If you have a main/parent activity, close it last:

public class App
{
    ////////////////////////////////////////////////////////////////
    // INSTANTIATED ACTIVITY VARIABLES
    ////////////////////////////////////////////////////////////////

        public static Activity activity1;
        public static Activity activity2;
        public static Activity activity3;

    ////////////////////////////////////////////////////////////////
    // CLOSE APP METHOD
    ////////////////////////////////////////////////////////////////

        public static void close()
        {
            if (App.activity3 != null) {App.activity3.finish();}
            if (App.activity2 != null) {App.activity2.finish();}
            if (App.activity1 != null) {App.activity1.finish();}
        }
}

Step 2 - in each of your activities, override the onStart() and onDestroy() methods. In onStart(), set the static variable in your App class equal to "this". In onDestroy(), set it equal to null. For example, in the "Activity1" class:

@Override
public void onStart()
{
    // RUN SUPER | REGISTER ACTIVITY AS INSTANTIATED IN APP CLASS

        super.onStart();
        App.activity1 = this;
}

@Override
public void onDestroy()
{
    // RUN SUPER | REGISTER ACTIVITY AS NULL IN APP CLASS

        super.onDestroy();
        App.activity1 = null;
}

Step 3 - When you want to close your app, simply call App.close() from anywhere. All instantiated activities will close! Since you are only closing activities and not killing the app itself (as in your examples), Android is free to take over from there and do any necessary cleanup.

Again, I don't know if this would be frowned upon for any reason. If so, I'd love to read comments on why it is and how it can be improved!

One solution is to run manually a shell function that sets my environment to work or personal, but I am pretty sure that I will often forget to switch to the correct identity resulting in committing under the wrong identity.

That was exactly my problem. I have written a hook script which warns you if you have any github remote and not defined a local username.

Here's how you set it up:

1. Create a directory to hold the global hook

   mkdir -p ~/.git-templates/hooks

2. Tell git to copy everything in ~/.git-templates to your per-project .git directory when you run git init or clone

   git config --global init.templatedir '~/.git-templates'

3. And now copy the following lines to ~/.git-templates/hooks/pre-commit and make the file executable (don't forget this otherwise git won't execute it!)

#!/bin/bash

RED='\033[0;31m' # red color
NC='\033[0m' # no color

GITHUB_REMOTE=$(git remote -v | grep github.com)
LOCAL_USERNAME=$(git config --local user.name)

if [ -n "$GITHUB_REMOTE" ] && [ -z "$LOCAL_USERNAME" ]; then
    printf "\n${RED}ATTENTION: At least one Github remote repository is configured, but no local username. "
    printf "Please define a local username that matches your Github account.${NC} [pre-commit hook]\n\n"
    exit 1
fi

If you use other hosts for your private repositories you have to replace github.com according to your needs.

Now every time you do a git init or git clone git will copy this script to the repository and executes it before any commit is done. If you have not set a local username it will output a warning and won't let you commit.

Actually if you downloaded the icons pack from the android web site, you will see that you have one folder per resolution named drawable-mdpi etc. Copy all folders into the res (not the drawable) folder in Android Studio. This will automatically make all the different resolution of the icon available.

Let us say we have a project social_login. To check the traffic to your repo, you can goto https://github.com//social_login/graphs/traffic

• Example:-

  https://github.com/balireddypraveen/social_login/graphs/traffic

A surprisingly fast approach is to use set:

a = ['a', 'b', 'c']
str = "a123"
if set(a) & set(str):
    print("some of the strings found in str")
else:
    print("no strings found in str")

This works if a does not contain any multiple-character values (in which case use any as listed above). If so, it's simpler to specify a as a string: a = 'abc'.

In a View, in my case a SurfaceView subclass, you can set the screen on always on. I wanted the screen to stay on while this view was still drawing stuff.

public class MyCoolSurfaceView extends SurfaceView { 
@Override
protected void onAttachedToWindow (){
    super.onAttachedToWindow();
    this.setKeepScreenOn(true);
}

@Override
protected void onDetachedFromWindow(){
    super.onDetachedFromWindow();
    this.setKeepScreenOn(false);
}

Recently I had to do something similar and I resolved it with the code below. Hope it helps!

Sub ColorCode()
Dim i As Integer
Dim j As Integer
i = 2
j = 1

Do While ActiveSheet.Cells(i, 1) <> ""


If Cells(i, 5).Value = "RED" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(255, 0, 0)



Else

If Cells(i, 5).Value = "GREEN" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(0, 255, 0)

Else

If Cells(i, 5).Value = "GREY" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(192, 192, 192)

Else

If Cells(i, 5).Value = "YELLOW" Then
ActiveSheet.ChartObjects("YourChartName").Chart.FullSeriesCollection(1).Points(j).MarkerForegroundColor = RGB(255, 255, 0)

End If
End If
End If
End If

i = i + 1
j = j + 1

Loop



End Sub

If you want to refer to a global variable in a function, you can use the global keyword to declare which variables are global. You don't have to use it in all cases (as someone here incorrectly claims) - if the name referenced in an expression cannot be found in local scope or scopes in the functions in which this function is defined, it is looked up among global variables.

However, if you assign to a new variable not declared as global in the function, it is implicitly declared as local, and it can overshadow any existing global variable with the same name.

Also, global variables are useful, contrary to some OOP zealots who claim otherwise - especially for smaller scripts, where OOP is overkill.

Just go to project.plist then add Supported interface orientation and then add only Portrait (bottom home button) and Portrait (top home button).

You can add or remove there orientation as per your project requirement .

.NET Framework provides many collection classes too. You can use Dictionary in C#. Please find the below msdn link for details and samples http://msdn.microsoft.com/en-us/library/xfhwa508.aspx

pull = fetch + merge.

You need to commit what you have done before merging.

So pull after commit.

You can use an event on the cell change to fire a macro that does the following:

vNew = Range("cellChanged").value
Application.EnableEvents = False
Application.Undo
vOld = Range("cellChanged").value
Range("cellChanged").value = vNew
Application.EnableEvents = True 

try this out

$("div[id^='car']:last").after($('#car2').clone());

the simplest way to convert a string that has a delimiter like a comma is just to use the split method

"1,2,3,4".split(',') # "1", "2", "3", "4"]

you can find more info on how to use the split method in the ruby docs

Divides str into substrings based on a delimiter, returning an array of these substrings.

If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.

If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters. If pattern contains groups, the respective matches will be returned in the array as well.

If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ‘ were specified.

If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.

Now that Javascript has lookbehind (as of ES2018), on newer environments, you can avoid groups entirely in situations like these. Rather, lookbehind for what comes before the group you were capturing, and lookahead for what comes after, and replace with just !NEW_ID!:

const str = 'name="some_text_0_some_text"';
console.log(
  str.replace(/(?<=name="\w+)\d+(?=\w+")/, '!NEW_ID!')
);

With this method, the full match is only the part that needs to be replaced.

• (?<=name="\w+) - Lookbehind for name=", followed by word characters (luckily, lookbehinds do not have to be fixed width in Javascript!)
• \d+ - Match one or more digits - the only part of the pattern not in a lookaround, the only part of the string that will be in the resulting match
• (?=\w+") - Lookahead for word characters followed by " `

Keep in mind that lookbehind is pretty new. It works in modern versions of V8 (including Chrome, Opera, and Node), but not in most other environments, at least not yet. So while you can reliably use lookbehind in Node and in your own browser (if it runs on a modern version of V8), it's not yet sufficiently supported by random clients (like on a public website).

The GNU site suggests this nice awk script, which prints both the words and their frequency.

Possible changes:

• You can pipe through sort -nr (and reverse word and freq[word]) to see the result in descending order.
• If you want a specific column, you can omit the for loop and simply write freq[3]++ - replace 3 with the column number.

Here goes:

 # wordfreq.awk --- print list of word frequencies

 {
     $0 = tolower($0)    # remove case distinctions
     # remove punctuation
     gsub(/[^[:alnum:]_[:blank:]]/, "", $0)
     for (i = 1; i <= NF; i++)
         freq[$i]++
 }

 END {
     for (word in freq)
         printf "%s\t%d\n", word, freq[word]
 }

There are some cases, when textbox will not handle enter key. I think it may be when you have accept button set on form. In that case, instead of KeyDown event you should use textbox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)

x = x + 1 print(x) a = x + 5 print(a)

Here is another option for Angular (using own formatting function) - this one is for format:

YYYY-mm-dd hh:nn:ss

-you can adjust to your formats, just re-order the lines and change separators

dateAsYYYYMMDDHHNNSS(date): string {
  return date.getFullYear()
            + '-' + this.leftpad(date.getMonth() + 1, 2)
            + '-' + this.leftpad(date.getDate(), 2)
            + ' ' + this.leftpad(date.getHours(), 2)
            + ':' + this.leftpad(date.getMinutes(), 2)
            + ':' + this.leftpad(date.getSeconds(), 2);
}

leftpad(val, resultLength = 2, leftpadChar = '0'): string {
  return (String(leftpadChar).repeat(resultLength)
        + String(val)).slice(String(val).length);
}

For current time stamp use like this:

const curTime = this.dateAsYYYYMMDDHHNNSS(new Date());
console.log(curTime);

Will output e.g: 2018-12-31 23:00:01

I have met the similar problem.

According to the log above,the most important information is:

Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output. Run with --scan to get full insights.

Most of the building problems of Gradle will be solved because when you use the specific Gradle build command,you can get more detailed and useful information that are clear.

*clean project
./gradlew clean  

*build project
./gradlew build

*build for debug package
./gradlew assembleDebug or ./gradlew aD

*build for release package
./gradlew assembleRelease or ./gradlew aR

*build for release package and install
./gradlew installRelease or ./gradlew iR Release

*build for debug package and install
./gradlew installDebug or ./gradlew iD Debug

*uninstall release package
./gradlew uninstallRelease or ./gradlew uR

*uninstall debug package
./gradlew uninstallDebug or ./gradlew uD 

*all the above command + "--info" or "--debug" or "--scan" or "--stacktrace" can get more detail information.

And then I found the problem is related with the version of Gradle,when I have changed Gradle from 5.0 to 4.1,and then it's OK.

The easiest way is to use date, which lets you mix hard-coded values with ones extracted from a timestamp. If you don't give a timestamp, it assumes the current date and time.

// Current timestamp is assumed, so these find first and last day of THIS month
$first_day_this_month = date('m-01-Y'); // hard-coded '01' for first day
$last_day_this_month  = date('m-t-Y');

// With timestamp, this gets last day of April 2010
$last_day_april_2010 = date('m-t-Y', strtotime('April 21, 2010'));

date() searches the string it's given, like 'm-t-Y', for specific symbols, and it replaces them with values from its timestamp. So we can use those symbols to extract the values and formatting that we want from the timestamp. In the examples above:

• Y gives you the 4-digit year from the timestamp ('2010')
• m gives you the numeric month from the timestamp, with a leading zero ('04')
• t gives you the number of days in the timestamp's month ('30')

You can be creative with this. For example, to get the first and last second of a month:

$timestamp    = strtotime('February 2012');
$first_second = date('m-01-Y 00:00:00', $timestamp);
$last_second  = date('m-t-Y 12:59:59', $timestamp); // A leap year!

See http://php.net/manual/en/function.date.php for other symbols and more details.

The following works very well

<empty line>
[whatever comment text]::

that method takes advantage of syntax to create links via reference
since link reference created with [1]: http://example.org will not be rendered, likewise any of the following will not be rendered as well

<empty line>
[whatever]::
[whatever]:whatever
[whatever]: :
[whatever]: whatever

In my case I had to check the Client ID type for web applications/installed applications.

installed applications: http://localhost [Redirect URIs] In this case localhost simply works

web applications: You need valid domain name [Redirect URIs:]
