You can also use the split() function. This seems to be the easiest one that comes to my mind :).

url.split('?')[0]

One advantage is this method will work even if there is no ? in the string - it will return the whole string.

https://github.com/requery/sqlite-android allows you to query JSON fields (and arrays in them, I've tried it and am using it). Before that I was just storing JSON strings into a TEXT column. It supports FTS3, FTS4, & JSON1

As of July 2019, it still gets version bumps every now and then, so it isn't a dead project.

• https://www.sqlite.org/fts3.html (perform full-text searches)

As per the comment by drris, if IsBodyHtml is set to true then a standard newline could potentially be ignored by design, I know you mention avoiding HTML but try using <br /> instead, even if just to see if this 'solves' the problem - then you can rule out by what you know:

var message = new System.Net.Mail.MailMessage();
message.Body = "First Line <br /> second line";

You may also just try setting IsBodyHtml to false and determining if newlines work in that instance, although, unless you set it to true explicitly I'm pretty sure it defaults to false anyway.

Also as a side note, avoiding HTML in emails is not necessarily any aid in getting the message through spam filters, AFAIK - if anything, the most you do by this is ensure cross-mail-client compatibility in terms of layout. To 'play nice' with spam filters, a number of other things ought to be taken into account; even so much as the subject and content of the mail, who the mail is sent from and where and do they match et cetera. An email simply won't be discriminated against because it is marked up with HTML.

Here is a simple expressjs solution if you just want to run this app locally and security is not a concern:

On your server.js or app.js file, add the following:

app.use('/local-files', express.static('/'));

That will serve your ENTIRE root directory under /local-files. Needless to say this is a really bad idea if you're planning to deploy this app anywhere other than your local machine.

Now, you can simply do:

<img src="/local-files/images/mypic.jps"/> 

note: I'm running macOS. If you're using Windows you may have to search and remove 'C:\' from the path string

print_r(json_decode('{"t":"\u00ed"}')); // -> stdClass Object ( [t] => í )

@mar10 comment was the missing piece I needed to do this.

Note that '/path/to/old/mercurial_repo' must be a path on the file system (not a URL), so you have to clone the original repository before. – mar10 Dec 27 '13 at 16:30

This comment was in regards to the answer that solved this for me, https://stackoverflow.com/a/10710294/2148757 which is the same answer as the one marked correct here, https://stackoverflow.com/a/16037861/2148757

This moved our hg project to git with the commit history intact.

I found the information found at http://help.infragistics.com/Help/NetAdvantage/jQuery/2013.1/CLR4.0/html/igOlapXmlaDataSource_Configuring_IIS_for_Cross_Domain_OLAP_Data.html to be very helpful in setting up HTTP OPTIONS for a WCF service in IIS 7.

I added the following to my web.config and then moved the OPTIONSVerbHandler in the IIS 7 'hander mappings' list to the top of the list. I also gave the OPTIONSVerbHander read access by double clicking the hander in the handler mappings section then on 'Request Restrictions' and then clicking on the access tab.

Unfortunately I quickly found that IE doesn't seem to support adding headers to their XDomainRequest object (setting the Content-Type to text/xml and adding a SOAPAction header).

Just wanted to share this as I spent the better part of a day looking for how to handle it.

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="*" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS" />
            <add name="Access-Control-Allow-Headers" value="Content-Type, soapaction" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

You need to read and write document.cookie

if (document.cookie.indexOf("visited=") >= 0) {
  // They've been here before.
  alert("hello again");
}
else {
  // set a new cookie
  expiry = new Date();
  expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes

  // Date()'s toGMTSting() method will format the date correctly for a cookie
  document.cookie = "visited=yes; expires=" + expiry.toGMTString();
  alert("this is your first time");
}

As mentioned in comments, this is a scoping issue. Specifically, $con is not in scope within your getPosts function.

You should pass your connection object in as a dependency, eg

function getPosts(mysqli $con) {
    // etc

I would also highly recommend halting execution if your connection fails or if errors occur. Something like this should suffice

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // throw exceptions
$con=mysqli_connect("localhost","xxxx","xxxx","xxxxx");

getPosts($con);

I found that only adding padding-top pushed down the grey dropdown arrow box on the right, which was undesirable.

The method that worked for me was to go into the inspector and incrementally add padding until the text was centered. This will also reduce the size of the dropdown icon, but it will be centered as well so it isn't as visually disturbing.

You can create a div like this:

<div class="image" style="background-image:url('/to/your/image')"></div>

And use this css to style it:

height: 100%;
width: 100%;
background-position: center center;
background-repeat: no-repeat;
background-size: contain; // this can also be cover

There's been a fair amount of recent research in considering how REST HTTP calls could replace the message queue concept.

If you introduce the concept of a process and a task as a resource, the need for middle messaging layer starts to evaporate.

Ex:

POST /task/name
    - Returns a 202 accepted status immediately
    - Returns a resource url for the created task: /task/name/X
    - Returns a resource url for the started process: /process/Y

GET /process/Y
    - Returns status of ongoing process

A task can have multiple steps for initialization, and a process can return status when polled or POST to a callback URL when complete.

This is dead simple, and becomes quite powerful when you realize that you can now subscribe to an rss/atom feed of all running processes and tasks without any middle layer. Any queuing system is going to require some sort of web front end anyway, and this concept has it built in without another layer of custom code.

Your resources exist until you delete them, which means you can view historical information long after the process and task complete.

You have built in service discovery, even for a task that has multiple steps, without any extra complicated protocols.

GET /task/name
    - returns form with required fields

POST (URL provided form's "action" attribute)

Your service discovery is an HTML form - a universal and human readable format.

The entire flow can be used programmatically or by a human, using universally accepted tools. It's a client driven, and therefore RESTful. Every tool created for the web can drive your business processes. You still have alternate message channels by POSTing asynchronously to a separate array of log servers.

After you consider it for a while, you sit back and start to realize that REST may just eliminate the need for a messaging queue and an ESB altogether.

http://www.infoq.com/presentations/BPM-with-REST

The cleanest fastest way:

processAlreadyRunning () {
    process="$(basename "${0}")"
    pidof -x "${process}" -o $$ &>/dev/null
}

Python does not have a defined entry point like Java, C, C++, etc. Rather it simply executes a source file line-by-line. The if statement allows you to create a main function which will be executed if your file is loaded as the "Main" module rather than as a library in another module.

To be clear, this means that the Python interpreter starts at the first line of a file and executes it. Executing lines like class Foobar: and def foobar() creates either a class or a function and stores them in memory for later use.

you can do this---

<input type="button" onClic="changebackColor">

function changebackColor(){
document.body.style.backgroundColor = "black";
document.getElementByID("divID").style.backgroundColor = "black";      
window.setTimeout("yourFunction()",10000);
}

I'm trying to redirect my current web site to other section on the same page, using JavaScript. This follow code work for me:

location.href='/otherSection'

In a query you can just do something like:

SELECT ColumnA * ColumnB FROM table

or

SELECT ColumnA - ColumnB FROM table

You can also create computed columns in your table where you can permanently use your formula.

Add the function:

function scrollToForm() {
  document.querySelector('#form').scrollIntoView({behavior: 'smooth'});
}

Trigger the function:

<a href="javascript: scrollToForm();">Jump to form</a>

You can get this one-liner to do what you want using Array.prototype.every, Object.is, and ES6 arrow functions:

const all = arr => arr.every(x => Object.is(arr[0], x));

I prefer simplicity...

private void _InvokeNamespaceClassesStaticMethod(string namespaceName, string methodName, params object[] parameters) {
    foreach(var _a in AppDomain.CurrentDomain.GetAssemblies()) {
        foreach(var _t in _a.GetTypes()) {
            try {
                if((_t.Namespace == namespaceName) && _t.IsClass) _t.GetMethod(methodName, (BindingFlags.Static | BindingFlags.Public))?.Invoke(null, parameters);
            } catch { }
        }
    }
}

Usage...

    _InvokeNamespaceClassesStaticMethod("mySolution.Macros", "Run");

But in case you're looking for something a little more robust, including the handling of exceptions...

private InvokeNamespaceClassStaticMethodResult[] _InvokeNamespaceClassStaticMethod(string namespaceName, string methodName, bool throwExceptions, params object[] parameters) {
    var results = new List<InvokeNamespaceClassStaticMethodResult>();
    foreach(var _a in AppDomain.CurrentDomain.GetAssemblies()) {
        foreach(var _t in _a.GetTypes()) {
            if((_t.Namespace == namespaceName) && _t.IsClass) {
                var method_t = _t.GetMethod(methodName, parameters.Select(_ => _.GetType()).ToArray());
                if((method_t != null) && method_t.IsPublic && method_t.IsStatic) {
                    var details_t = new InvokeNamespaceClassStaticMethodResult();
                    details_t.Namespace = _t.Namespace;
                    details_t.Class = _t.Name;
                    details_t.Method = method_t.Name;
                    try {
                        if(method_t.ReturnType == typeof(void)) {
                            method_t.Invoke(null, parameters);
                            details_t.Void = true;
                        } else {
                            details_t.Return = method_t.Invoke(null, parameters);
                        }
                    } catch(Exception ex) {
                        if(throwExceptions) {
                            throw;
                        } else {
                            details_t.Exception = ex;
                        }
                    }
                    results.Add(details_t);
                }
            }
        }
    }
    return results.ToArray();
}

private class InvokeNamespaceClassStaticMethodResult {
    public string Namespace;
    public string Class;
    public string Method;
    public object Return;
    public bool Void;
    public Exception Exception;
}

Usage is pretty much the same...

_InvokeNamespaceClassesStaticMethod("mySolution.Macros", "Run", false);

• chmod +w <directory> or chmod a+w <directory> - Write permission for user, group and others

CASE by definition only returns a single value. Ever.

It also (almost always) short circuits, which means if your first condition is met no other checks are run.

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

This works if the value contains a space:

FOR /F "skip=2 tokens=1,2*" %%A IN ('REG QUERY "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul') DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C
)

if defined ValueName (
    echo Value Name = %ValueName%
    echo Value Type = %ValueType%
    echo Value Value = %ValueValue%
) else (
    @echo "%KEY_NAME%"\"%VALUE_NAME%" not found.
)

Strange but true: if acceptable (i.e. result is void and you don't mind letting the runloop cycle once), add a delay, even if this is zero:

[_controller performSelector:NSSelectorFromString(@"someMethod")
    withObject:nil
    afterDelay:0];

This removes the warning, presumably because it reassures the compiler that no object can be returned and somehow mismanaged.

The opposite of this is to flatten a column into a csv eg

SELECT STRING_AGG ([value],',') FROM STRING_SPLIT('Akio,Hiraku,Kazuo', ',')

This thread already has some great answers, but I feel I can bring a little more detail with this additional answer.

First, remember that a namespace declaration with periods, like:

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    ...
}

is entirely equivalent to:

namespace MyCorp
{
    namespace TheProduct
    {
        namespace SomeModule
        {
            namespace Utilities
            {
                ...
            }
        }
    }
}

If you wanted to, you could put using directives on all of these levels. (Of course, we want to have usings in only one place, but it would be legal according to the language.)

The rule for resolving which type is implied, can be loosely stated like this: First search the inner-most "scope" for a match, if nothing is found there go out one level to the next scope and search there, and so on, until a match is found. If at some level more than one match is found, if one of the types are from the current assembly, pick that one and issue a compiler warning. Otherwise, give up (compile-time error).

Now, let's be explicit about what this means in a concrete example with the two major conventions.

(1) With usings outside:

using System;
using System.Collections.Generic;
using System.Linq;
//using MyCorp.TheProduct;  <-- uncommenting this would change nothing
using MyCorp.TheProduct.OtherModule;
using MyCorp.TheProduct.OtherModule.Integration;
using ThirdParty;

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    class C
    {
        Ambiguous a;
    }
}

In the above case, to find out what type Ambiguous is, the search goes in this order:

1. Nested types inside C (including inherited nested types)
2. Types in the current namespace MyCorp.TheProduct.SomeModule.Utilities
3. Types in namespace MyCorp.TheProduct.SomeModule
4. Types in MyCorp.TheProduct
5. Types in MyCorp
6. Types in the null namespace (the global namespace)
7. Types in System, System.Collections.Generic, System.Linq, MyCorp.TheProduct.OtherModule, MyCorp.TheProduct.OtherModule.Integration, and ThirdParty

The other convention:

(2) With usings inside:

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using MyCorp.TheProduct;                           // MyCorp can be left out; this using is NOT redundant
    using MyCorp.TheProduct.OtherModule;               // MyCorp.TheProduct can be left out
    using MyCorp.TheProduct.OtherModule.Integration;   // MyCorp.TheProduct can be left out
    using ThirdParty;

    class C
    {
        Ambiguous a;
    }
}

Now, search for the type Ambiguous goes in this order:

1. Nested types inside C (including inherited nested types)
2. Types in the current namespace MyCorp.TheProduct.SomeModule.Utilities
3. Types in System, System.Collections.Generic, System.Linq, MyCorp.TheProduct, MyCorp.TheProduct.OtherModule, MyCorp.TheProduct.OtherModule.Integration, and ThirdParty
4. Types in namespace MyCorp.TheProduct.SomeModule
5. Types in MyCorp
6. Types in the null namespace (the global namespace)

(Note that MyCorp.TheProduct was a part of "3." and was therefore not needed between "4." and "5.".)

Concluding remarks

No matter if you put the usings inside or outside the namespace declaration, there's always the possibility that someone later adds a new type with identical name to one of the namespaces which have higher priority.

Also, if a nested namespace has the same name as a type, it can cause problems.

It is always dangerous to move the usings from one location to another because the search hierarchy changes, and another type may be found. Therefore, choose one convention and stick to it, so that you won't have to ever move usings.

Visual Studio's templates, by default, put the usings outside of the namespace (for example if you make VS generate a new class in a new file).

One (tiny) advantage of having usings outside is that you can then utilize the using directives for a global attribute, for example [assembly: ComVisible(false)] instead of [assembly: System.Runtime.InteropServices.ComVisible(false)].

Firewalls are often the problem in these situations. Personally, the Mcafee enterprise firewall was causing this issue even for requests within the network.

Disable your firewalls or add a rule for tomcat and see if this helps.

"FetchType.LAZY" will only fire for primary table. If in your code you call any other method that has a parent table dependency then it will fire query to get that table information. (FIRES MULTIPLE SELECT)

"FetchType.EAGER" will create join of all table including relevant parent tables directly. (USES JOIN)

When to Use: Suppose you compulsorily need to use dependant parent table informartion then choose FetchType.EAGER. If you only need information for certain records then use FetchType.LAZY.

Remember, FetchType.LAZY needs an active db session factory at the place in your code where if you choose to retrieve parent table information.

E.g. for LAZY:

.. Place fetched from db from your dao loayer
.. only place table information retrieved
.. some code
.. getCity() method called... Here db request will be fired to get city table info

You need to set the password for root@localhost to be blank. There are two ways:

1. The MySQL SET PASSWORD command:

   SET PASSWORD FOR root@localhost=PASSWORD('');
   

2. Using the command-line mysqladmin tool:

   mysqladmin -u root -pType_in_your_current_password_here password ''
   

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system) or larger. Data alignment means putting the data at a memory address equal to some multiple of the word size, which increases the system’s performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

1. In order to align the data in memory, one or more empty bytes (addresses) are inserted (or left empty) between memory addresses which are allocated for other structure members while memory allocation. This concept is called structure padding.
2. Architecture of a computer processor is such a way that it can read 1 word (4 byte in 32 bit processor) from memory at a time.
3. To make use of this advantage of processor, data are always aligned as 4 bytes package which leads to insert empty addresses between other member’s address.
4. Because of this structure padding concept in C, size of the structure is always not same as what we think.

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

You could iterate over the anonymous type's properties using Reflection; see if there is a "Checked" property and if there is then get its value.

See this blog post: http://blogs.msdn.com/wriju/archive/2007/10/26/c-3-0-anonymous-type-and-net-reflection-hand-in-hand.aspx

So something like:

foreach(object o in nodes)
{
    Type t = o.GetType();

    PropertyInfo[] pi = t.GetProperties(); 

    foreach (PropertyInfo p in pi)
    {
        if (p.Name=="Checked" && !(bool)p.GetValue(o))
            Console.WriteLine("awesome!");
    }
}

Radio buttons would only need to be read-only if there are other options. If you don't have any other options, a checked radio button cannot be unchecked. If you have other options, you can prevent the user from changing the value merely by disabling the other options:

<input type="radio" name="foo" value="Y" checked>
<input type="radio" name="foo" value="N" disabled>

Using plaintext may not be the best choice, if the password is ever used as something else.

I support the accepted answer, but it didn't work for me - for a very specific reason: I wanted to use either kwallet or gnome-keyring password stores. I tried changing the settings, all over the four files:

/etc/subversion/config
/etc/subversion/servers
~/.subversion/config
~/.subversion/servers

Even after it all was set the same, with password-stores and KWallet name (default might be wrong, right?) it didn't work and kept asking for password forever. The files in ~/.subversion had permissions 600.

Well, at that point, you may try to check one simple thing:

which svn

If you get:

/usr/bin/local/svn

then you may suspect with great likelihood that this client was built from source, locally, by your administrator (which may be yourself, as in my case).

Subversion is a nasty beast to compile, very easy to accidentally build without HTTP support, or - as in my example - without support for encrypted password stores (you need either Gnome or KDE development files, and a lot of them!). But the ./configure script won't tell you that, and you just get a less functional svn command.

In that case, you may go back to the client, which came with your distribution, usually in /usr/bin/svn. The downside is - you'll probably need to re-checkout the working copies, as there is no svn downgrade command. You can consult Linus Torvalds on what to think about Subversion, anyway ;)

If pip doesn't come with your installation of python 3.6, this may work:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3.6 get-pip.py

then you can python -m install

The question has been asked on serverfault too.

You may want to take a look at this article which explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.

The simplest way to fix this is to use the Barracuda file format with InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.

The method that worked for the OP there was:

1. Add the following to the my.cnf file under [mysqld] section.

   innodb_file_per_table=1
   innodb_file_format = Barracuda
   

2. ALTER the table to use ROW_FORMAT=COMPRESSED.

   ALTER TABLE nombre_tabla
       ENGINE=InnoDB
       ROW_FORMAT=COMPRESSED 
       KEY_BLOCK_SIZE=8;
   

There is a possibility that the above still does not resolve your issues. It is a known (and verified) bug with the InnoDB engine, and a temporary fix for now is to fallback to MyISAM engine as temporary storage. So, in your my.cnf file:

internal_tmp_disk_storage_engine=MyISAM

If you have a Linux-Machine you could use the free command-line tool SAXCount. I found this very usefull.

SAXCount -f -s -n my.xml

It validates against dtd and xsd. 5s for a 50MB file.

In debian squeeze it is located in the package "libxerces-c-samples".

The definition of the dtd and xsd has to be in the xml! You can't config them separately.

Starting from Postman 8 you need to visit here

if(data.trim()==''){alert("Nothing Found");}

Use .AddWithValue(), So:

sqlComm.Parameters.AddWithValue("@Age", sb.ToString().TrimEnd(','));

Alternatively, you could use this:

sqlComm.Parameters.Add(
    new SqlParameter("@Age", sb.ToString().TrimEnd(',')) { SqlDbType = SqlDbType. NVarChar }
    );

Your total code sample will look at follows then:

string sqlCommand = "SELECT * from TableA WHERE Age IN (@Age)";
SqlConnection sqlCon = new SqlConnection(connectString);
SqlCommand sqlComm = new SqlCommand();
sqlComm.Connection = sqlCon;
sqlComm.CommandType = System.Data.CommandType.Text;
sqlComm.CommandText = sqlCommand;
sqlComm.CommandTimeout = 300;

StringBuilder sb = new StringBuilder();
foreach (ListItem item in ddlAge.Items)
{
     if (item.Selected)
     {
         sb.Append(item.Text + ",");
     }
}

sqlComm.Parameters.AddWithValue("@Age", sb.ToString().TrimEnd(','));

// OR

// sqlComm.Parameters.Add(new SqlParameter("@Age", sb.ToString().TrimEnd(',')) { SqlDbType = SqlDbType. NVarChar });

Radio buttons have another attribute - checked or unchecked. You need to set which button was selected by the user, so you have to write PHP code inside the HTML with these values - checked or unchecked. Here's one way to do it:

The PHP code:

<?PHP
    $male_status = 'unchecked';
    $female_status = 'unchecked';

    if (isset($_POST['Submit1'])) {
         $selected_radio = $_POST['gender'];

         if ($selected_radio == 'male') {
                $male_status = 'checked';
          }else if ($selected_radio == 'female') {
                $female_status = 'checked';
          }
    }
?>

The HTML FORM code:

<FORM name ="form1" method ="post" action ="radioButton.php">
   <Input type = 'Radio' Name ='gender' value= 'male'
   <?PHP print $male_status; ?>
   >Male
   <Input type = 'Radio' Name ='gender' value= 'female' 
   <?PHP print $female_status; ?>
   >Female
   <P>
   <Input type = "Submit" Name = "Submit1" VALUE = "Select a Radio Button">
</FORM>

Implemented the same in scala, Please help urself with converting to Java, the core logic and functions used stays the same.

import java.text.SimpleDateFormat
import org.apache.commons.lang.time.DateUtils

object MultiDataFormat {
  def main(args: Array[String]) {

val dates =Array("2015-10-31","26/12/2015","19-10-2016")

val possibleDateFormats:Array[String] = Array("yyyy-MM-dd","dd/MM/yyyy","dd-MM-yyyy")

val sdf =  new SimpleDateFormat("yyyy-MM-dd") //change it as per the requirement
  for (date<-dates) {
    val outputDate = DateUtils.parseDateStrictly(date, possibleDateFormats)
    System.out.println("inputDate ==> " + date + ", outputDate ==> " +outputDate + " " + sdf.format(outputDate) )
  }
}

}

Implement your adapter Filterable:

public class vJournalAdapter extends ArrayAdapter<JournalModel> implements Filterable{
private ArrayList<JournalModel> items;
private Context mContext;
....

then create your Filter class:

private class JournalFilter extends Filter{

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults result = new FilterResults();
        List<JournalModel> allJournals = getAllJournals();
        if(constraint == null || constraint.length() == 0){

            result.values = allJournals;
            result.count = allJournals.size();
        }else{
            ArrayList<JournalModel> filteredList = new ArrayList<JournalModel>();
            for(JournalModel j: allJournals){
                if(j.source.title.contains(constraint))
                    filteredList.add(j);
            }
            result.values = filteredList;
            result.count = filteredList.size();
        }

        return result;
    }
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        if (results.count == 0) {
            notifyDataSetInvalidated();
        } else {
            items = (ArrayList<JournalModel>) results.values;
            notifyDataSetChanged();
        }
    }

}

this way, your adapter is Filterable, you can pass filter item to adapter's filter and do the work. I hope this will be helpful.

You would do something like this to get the path "Data\ich_will.mp3" inside your application environments folder.

string fileName = "ich_will.mp3";
string path = Path.Combine(Environment.CurrentDirectory, @"Data\", fileName);

In my case it would return the following:

C:\MyProjects\Music\MusicApp\bin\Debug\Data\ich_will.mp3

I use Path.Combine and Environment.CurrentDirectory in my example. These are very useful and allows you to build a path based on the current location of your application. Path.Combine combines two or more strings to create a location, and Environment.CurrentDirectory provides you with the working directory of your application.

The working directory is not necessarily the same path as where your executable is located, but in most cases it should be, unless specified otherwise.

I got the same error for a simple bash script that wouldn't have 32/64-bit issues. This is possibly because the script you are trying to run has an error in it. This ubuntu forum post indicates that with normal script files you can add 'sh' in front and you might get some debug output from it. e.g.

$ sudo sh arm-mingw32ce-g++

and see if you get any output.

In my case the actual problem was that the file that I was trying to execute was in Windows format rather than linux.

The existing answers all seem to run this script in a DOS console window.

This may be acceptable, but for example means that colour codes (changing text colour) don't work but instead get printed out as they are:

there is no item "[032mGroovy[0m"

I found this solution some time ago, so I'm not sure whether mintty.exe is a standard Cygwin utility or whether you have to run the setup program to get it, but I run like this:

D:\apps\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico  bash.exe .\myShellScript.sh

... this causes the script to run in a Cygwin BASH console instead of a Windows DOS console.

Just added to mrjandro's solution a quick hack to get rid of simple connection errors / timeouts.

You can adjust the threshold changing max_error_count variable value and add notifications of any sort.

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors 
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print "Error counter: " + str(error_count)
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print "Sending out notification"
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print "Port is open"
else:
        print "Port is not open"
        increase_error_count()

And here you find a Python 3 compatible version (just fixed print syntax):

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print ("Error counter: " + str(error_count))
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print ("Sending out notification")
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print ("Port is open")
else:
        print ("Port is not open")
        increase_error_count()

Send a ajax request to your server like this in your js and get your result in success function.

jQuery.ajax({
            url: "/rest/abc",
            type: "GET",

            contentType: 'application/json; charset=utf-8',
            success: function(resultData) {
                //here is your json.
                  // process it

            },
            error : function(jqXHR, textStatus, errorThrown) {
            },

            timeout: 120000,
        });

at server side send response as json type.

And you can use jQuery.getJSON for your application.

Terminal > su > password > vim /etc/vimrc

Using solve with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.

What you want is actually possible now. If you can run the asynchronous code in a service worker, and the synchronous code in a web worker, then you can have the web worker send a synchronous XHR to the service worker, and while the service worker does the async things, the web worker's thread will wait. This is not a great approach, but it could work.

The above answers are all fine, but the essence of the issue is that some headers are set one way, and others are set other ways. See above for 'restricted header' lists. FOr these, you just set them as a property. For others, you actually add the header. See here.

    request.ContentType = "application/x-www-form-urlencoded";

    request.Accept = "application/json";

    request.Headers.Add(HttpRequestHeader.Authorization, "Basic " + info.clientId + ":" + info.clientSecret);

start from

JSONArray deletedtrs_array = sync_reponse.getJSONArray("deletedtrs");

you can iterate through JSONArray and use values directly or create Objects of your own type
which will handle data fields inside of each deletedtrs_array member

Iterating

for(int i = 0; i < deletedtrs_array.length(); i++){
    JSONObject obj = deletedtrs_array.getJSONObject(i);
    Log.d("Item no."+i, obj.toString());

    // create object of type DeletedTrsWrapper like this
    DeletedTrsWrapper dtw = new DeletedTrsWrapper(obj);

    // String company_id = obj.getString("companyid");
    // String username = obj.getString("username");
    // String date = obj.getString("date");
    // int report_id = obj.getInt("reportid");
}

Own object type

class DeletedTrsWrapper {

    public String company_id;
    public String username;
    public String date;
    public int report_id;

    public DeletedTrsWrapper(JSONObject obj){
        company_id = obj.getString("companyid");
        username = obj.getString("username");
        date = obj.getString("date");
        report_id = obj.getInt("reportid");
    }
}

Use the -J compression option for xz. And remember to man tar :)

tar cfJ <archive.tar.xz> <files>

Edit 2015-08-10:

If you're passing the arguments to tar with dashes (ex: tar -cf as opposed to tar cf), then the -f option must come last, since it specifies the filename (thanks to @A-B-B for pointing that out!). In that case, the command looks like:

tar -cJf <archive.tar.xz> <files>

Whether you're running within the context of ASP.NET or not, you should be able to use HostingEnvironment.ApplicationPhysicalPath

Lightly changed Mikael Svenson code. I found the week of the first monday and appropriate change the week number.

 DateTime GetFirstWeekDay(int year, int weekNum)
    {
        Calendar calendar = CultureInfo.CurrentCulture.Calendar;

        DateTime jan1 = new DateTime(year, 1, 1);

        int daysOffset = DayOfWeek.Monday - jan1.DayOfWeek;
        DateTime firstMonday = jan1.AddDays(daysOffset);
        int firstMondayWeekNum = calendar.GetWeekOfYear(firstMonday, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);

        DateTime firstWeekDay = firstMonday.AddDays((weekNum-firstMondayWeekNum) * 7);

        return firstWeekDay;
    }

In my case the width of the contentView was greater than the width of UIScrollView and that was the reason for unwanted horizontal scrolling. I solved it by setting the width of contentView equal to width of UIScrollView.

Hope it helps someone

Same issue as in Error in launching AVD:

1) Install the Intel x86 Emulator Accelerator (HAXM installer) from the Android SDK Manager;

2) Run (for Windows):

{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

or (for OSX):

{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHAXM_1.1.1_for_10_9_and_above.dmg

3) Start the emulator.

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

Can't post comments yet, but @Cristi S's answer works a treat for me.

In my scenario, I needed to keep only the most recent 3 records in Lowest_Offers for all product_ids.

Need to rework his SQL to delete - thought that this would be ok, but syntax is wrong.

DELETE from (
SELECT product_id, id, date_checked,
  ROW_NUMBER() OVER (PARTITION BY product_id ORDER BY date_checked DESC) rn
FROM lowest_offers
) tmp WHERE > 3;

i had a similiar problem and the gem string-scrub automagically fixed it for me. https://github.com/hsbt/string-scrub If the given string contains an invalid byte sequence then that invalid byte sequence is replaced with the unicode replacement character (?) and a new string is returned.

For use datetime from input value, just set option useCurrent to false, and set in value the date

$('#datetimepicker1').datetimepicker({_x000D_
  useCurrent: false,_x000D_
  format: 'DD.MM.YYYY H:mm'_x000D_
});

faced the same issue, the solution that worked for me:

Instead of mocking the service interface, I used @InjectMocks to mock the service implementation:

@InjectMocks
private exampleServiceImpl exampleServiceMock;

instead of :

@Mock
private exampleService exampleServiceMock;

You can get the scrollbar size and then apply a margin to the container.

Something like this:

var checkScrollBars = function(){
    var b = $('body');
    var normalw = 0;
    var scrollw = 0;
    if(b.prop('scrollHeight')>b.height()){
        normalw = window.innerWidth;
        scrollw = normalw - b.width();
        $('#container').css({marginRight:'-'+scrollw+'px'});
    }
}

CSS for remove the h-scrollbar:

body{
    overflow-x:hidden;
}

Try to take a look at this: http://jsfiddle.net/NQAzt/

Call nrow passing as argument the name of the dataset:

nrow(dataset)

import os 
zip_file_path = "C:\AA\BB"
file_list = os.listdir(path)
abs_path = []
for a in file_list:
    x = zip_file_path+'\\'+a
    print x
    abs_path.append(x)
for f in abs_path:
    zip=zipfile.ZipFile(f)
    zip.extractall(zip_file_path)

This does not contain validation for the file if its not zip. If the folder contains non .zip file it will fail.

Doing borders on tables with css is a bit more complicated (but not as much, see this jsfiddle as example):

table {_x000D_
  border-collapse: collapse;_x000D_
  border: 1px solid black;_x000D_
}_x000D_
_x000D_
table td {_x000D_
  border: 1px solid black;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>test</td>_x000D_
    <td>test</td>_x000D_
  </tr>_x000D_
</table>

Two arrays can be easily added or union without chaning their original indexing by + operator. This will be very help full in laravel and codeigniter select dropdown.

 $empty_option = array(
         ''=>'Select Option'
          );

 $option_list = array(
          1=>'Red',
          2=>'White',
          3=>'Green',
         );

  $arr_option = $empty_option + $option_list;

Output will be :

$arr_option = array(
   ''=>'Select Option'
   1=>'Red',
   2=>'White',
   3=>'Green',
 );

I was looking at the different answers and took time to read the documentation of secrets

The secrets module is used for generating cryptographically strong random numbers suitable for managing data such as passwords, account authentication, security tokens, and related secrets.

In particularly, secrets should be used in preference to the default pseudo-random number generator in the random module, which is designed for modelling and simulation, not security or cryptography.

Looking more into what it has to offer I found a very handy function if you want to mimic an ID like Google Drive IDs:

secrets.token_urlsafe([nbytes=None])
Return a random URL-safe text string, containing nbytes random bytes. The text is Base64 encoded, so on average each byte results in approximately 1.3 characters. If nbytes is None or not supplied, a reasonable default is used.

Use it the following way:

import secrets
import math

def id_generator():
    id = secrets.token_urlsafe(math.floor(32 / 1.3))
    return id

print(id_generator())

Output a 32 characters length id:

I know this is slightly different from the OP's question but I expect that it would still be helpful to many who were looking for the same use-case that I was looking for.

Not the best way to error log, but you can always set everything to an array for the promiseAll, and store the resulting results into new variables.

If you use graphQL you need to postprocess the response regardless and if it doesn't find the correct reference it'll crash the app, narrowing down where the problem is at

const results = await Promise.all([
  this.props.client.query({
    query: GET_SPECIAL_DATES,
  }),
  this.props.client.query({
    query: GET_SPECIAL_DATE_TYPES,
  }),
  this.props.client.query({
    query: GET_ORDER_DATES,
  }),
]).catch(e=>console.log(e,"error"));
const specialDates = results[0].data.specialDates;
const specialDateTypes = results[1].data.specialDateTypes;
const orderDates = results[2].data.orders;

I have changed the order of included projects (Eclipse / Configure Build Path / Order and Export). I have moved my two dependent projects to the top of the "Order and Export" list. It solved the problem "NoClassDefFoundError".

It is strange for me. I didn't heard about the importance of the order of included libraries and projects. Android + Eclipse is fun :)

This is an alternative:

- name: Install this only for local dev machine
  pip: name=pyramid
  delegate_to: localhost

str="abcdef"

str.index('c') #=> 2 #String matching approach
str=~/c/ #=> 2 #Regexp approach 
$~ #=> #<MatchData "c">

Hope it helps. :)

.hover() function accepts two function arguments, one for mouseenter event and one for mouseleave event.

This will get you to an answer for your simple case, but can you expand on how you'll know which columns will need to be compared (B and C in this case) and what the initial range (A1:D5 in this case) will be? Then I can try to provide a more complete answer.

Sub setCondFormat()
    Range("B3").Select
    With Range("B3:H63")
        .FormatConditions.Add Type:=xlExpression, Formula1:= _
          "=IF($D3="""",FALSE,IF($F3>=$E3,TRUE,FALSE))"
        With .FormatConditions(.FormatConditions.Count)
            .SetFirstPriority
            With .Interior
                .PatternColorIndex = xlAutomatic
                .Color = 5287936
                .TintAndShade = 0
            End With
        End With
    End With
End Sub

Note: this is tested in Excel 2010.

Edit: Updated code based on comments.

If you really want a vba solution you can loop through a range like this:

Sub Check()
    Dim dat As Variant
    Dim rng As Range
    Dim i As Long

    Set rng = Range("A1:A100")
    dat = rng
    For i = LBound(dat, 1) To UBound(dat, 1)
        If dat(i, 1) <> "" Then
            rng(i, 2).Value = "My Text"
        End If
    Next
End Sub

*EDIT*

Instead of using varients you can just loop through the range like this:

Sub Check()
    Dim rng As Range
    Dim i As Long

    'Set the range in column A you want to loop through
    Set rng = Range("A1:A100")
    For Each cell In rng
        'test if cell is empty

Intellij had .ignore plugin to support this. https://plugins.jetbrains.com/plugin/7495?pr=idea

After you install the plugin, you right click on the project and select new -> .ignore file -> .gitignore file (Git)

Then, select the type of project you have to generate a template and click Generate.

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.

I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).

This does not answer your question, but I faced a similar error message but due to a different reason. Allow me to make my post for the sake of information collection.

I have a git repo on a network drive. Let's call this network drive RAID. I cloned this repo on my local machine (LOCAL) and on my number crunching cluster (CRUNCHER). For convenience I mounted the user directory of my account on CRUNCHER on my local machine. So, I can manipulate files on CRUNCHER without the need to do the work in an SSH terminal.

Today, I was modifying files in the repo on CRUNCHER via my local machine. At some point I decided to commit the files, so a did a commit. Adding the modified files and doing the commit worked as I expected, but when I called git push I got an error message similar to the one posted in the question.

The reason was, that I called push from within the repo on CRUNCHER on LOCAL. So, all paths in the config file were plain wrong.

When I realized my fault, I logged onto CRUNCHER via Terminal and was able to push the commit.

Feel free to comment if my explanation can't be understood, or you find my post superfluous.

The easiest solution I found is to just rename the php folder version as such:

1. Shut down the servers
2. Rename the folder containing the php version that you don't need in /Applications/MAMP/bin/php. php7.3.9 --> _php7.3.9

That way only two of them will be read by MAMP. Done!

In Android Studio 3.2.1 I got this error because I installed a new API(28) level emulator without installing that API SDK components. After I installed SDK platform and SDK platform tools for the API level 28 and updated Android Emulator the emulator started running.

Hope it may help someone.

Couple of ways. Firstly, if you're adding a row each time a [de]activation occurs, you can set the column default to GETDATE() and not set the value in the insert. Otherwise,

UPDATE TableName SET [ColumnName] = GETDATE() WHERE UserId = @userId

Assuming you have access to them (the properties you've declared are protected), you use them like this:

Person tom = new Person();
tom.Title = "A title";
string hisTitle = tom.Title;

These are properties. They're basically pairs of getter/setter methods (although you can have just a getter, or just a setter) with appropriate metadata. The example you've given is of automatically implemented properties where the compiler is adding a backing field. You can write the code yourself though. For example, the Title property you've declared is like this:

private string title; // Backing field
protected string Title
{
    get { return title; }  // Getter
    set { title = value; } // Setter
}

... except that the backing field is given an "unspeakable name" - one you can't refer to in your C# code. You're forced to go through the property itself.

You can make one part of a property more restricted than another. For example, this is quite common:

private string foo;
public string Foo
{
    get { return foo; }
    private set { foo = value; }
}

or as an automatically implemented property:

public string Foo { get; private set; }

Here the "getter" is public but the "setter" is private.

Looks like above solutions aren't using compare method and implementing total again so here is my solution and hope it works for you (It's working fine).

#include<iostream>
#include<cstring>
#include<cmath>
using namespace std;
string tolow(string a)
{
    for(unsigned int i=0;i<a.length();i++)
    {
        a[i]=tolower(a[i]);
    }
    return a;
}
int main()
{
    string str1,str2;
    cin>>str1>>str2;
    int temp=tolow(str1).compare(tolow(str2));
    if(temp>0)
        cout<<1;
    else if(temp==0)
        cout<<0;
    else
        cout<<-1;
}

If you have HashMap<String, SomeObject> hashMap then:

hashMap.values().toArray();

Will return an Object[]. If instead you want an array of the type SomeObject, you could use:

hashMap.values().toArray(new SomeObject[0]);

You can try this - it takes special care to only remove leading zeroes if needed:

DECLARE @LeadingZeros    VARCHAR(10) ='-000987000'

SET @LeadingZeros =
      CASE WHEN PATINDEX('%-0', @LeadingZeros) = 1   THEN 
           @LeadingZeros
      ELSE 
           CAST(CAST(@LeadingZeros AS INT) AS VARCHAR(10)) 
      END   

SELECT @LeadingZeros

Or you can simply call

CAST(CAST(@LeadingZeros AS INT) AS VARCHAR(10)) 

getting username in MAC terminal is easy...

I generally use whoami in terminal...

For example, in this case, I needed that to install Tomcat Server...

I don't think you need/want the timeout.

onhover (hover) would be defined as the time period while "over" something. IMHO

onmouseover = start...

onmouseout = ...end

For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.

Installing node_modules in container to different from project folder, and setting NODE_PATH to your node_modules folder helps me (u need to rebuild container).

I'm using docker-compose. My project file structure:

-/myproject
--docker-compose.yml
--nodejs/
----Dockerfile

docker-compose.yml:

version: '2'
services:
  nodejs:
    image: myproject/nodejs
    build: ./nodejs/.
    volumes:
      - ./nodejs:/workdir
    ports:
      - "23005:3000"
    command: npm run server

Dockerfile in nodejs folder:

FROM node:argon
RUN mkdir /workdir
COPY ./package.json /workdir/.
RUN mkdir /data
RUN ln -s /workdir/package.json /data/.

The Strings in double quotes always confuse me, so I think answer to this question needs some graphical presentation to clear this out.

For a banking app, I have a LoginViewController and a BalanceViewController. Each have their respective screens.

The app starts and shows the Login screen. When login is successful, app opens the Balance screen.

Here is how it looks:

The login success is handled like this:

let storyBoard: UIStoryboard = UIStoryboard(name: "Balance", bundle: nil)
let balanceViewController = storyBoard.instantiateViewController(withIdentifier: "balance") as! BalanceViewController
self.present(balanceViewController, animated: true, completion: nil)

As you can see, the storyboard ID 'balance' in small letters is what goes in the second line of the code, and this is the ID which is defined in the storyboard settings, as in the attached screenshot.

The term 'Balance' with capital 'B' is the name of the storyboard file, which is used in the first line of the code.

We know that using hard coded Strings in code is a very bad practice, but somehow in iOS development it has become a common practice, and Xcode doesn't even warn about them.

If you have to do group by using hibernate criteria use projections.groupPropery like the following,

@Autowired
private SessionFactory sessionFactory;
Criteria crit = sessionFactory.getCurrentSession().createCriteria(studentModel.class);
crit.setProjection(Projections.projectionList()
            .add(Projections.groupProperty("studentName").as("name"))
List result = crit.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP).list(); 
return result;  

Check

SELECT @@sql_mode;

if you see 'ZERO_DATE' stuff in there, try

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'NO_ZERO_DATE',''));   
SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'NO_ZERO_IN_DATE',''));   

Log out and back in again to your client (this is strange) and try again

If you have installed Batarang

Then you can just write:

$scope

when you have the element selected in the elements view in chrome. Ref - https://github.com/angular/angularjs-batarang#console

Unfortunately there is only the function setColumnWidth(int columnIndex, int width) from class Sheet; in which width is a number of characters in the standard font (first font in the workbook) if your fonts are changing you cannot use it. There is explained how to calculate the width in function of a font size. The formula is:

width = Truncate([{NumOfVisibleChar} * {MaxDigitWidth} + {5PixelPadding}] / {MaxDigitWidth}*256) / 256

You can always use autoSizeColumn(int column, boolean useMergedCells) after inputting the data in your Sheet.

To reverse

byte[] bytemsg=msg.getBytes(); 

you can use

String text = new String(bytemsg); 

using a BigInteger just complicates things, in fact it not clear why you want a byte[]. What are planing to do with the BigInteger or byte[]? What is the point?

Installing bzip2 and zip PHP extensions solved my issue in Ubuntu:

sudo apt-get install php7.0-bz2
sudo apt-get install php7.0-zip

Use php(you version)-(extension) to install and enable any missing modules that is required in the phpmyadmin readme.

To get more information use this custom TO($someObject) function:

I wrote this simple function which not only displays the methods of a given object, but also shows its properties, encapsulation and some other useful information like release notes if given.

function TO($object){ //Test Object
                if(!is_object($object)){
                    throw new Exception("This is not a Object"); 
                    return;
                }
                if(class_exists(get_class($object), true)) echo "<pre>CLASS NAME = ".get_class($object);
                $reflection = new ReflectionClass(get_class($object));
                echo "<br />";
                echo $reflection->getDocComment();

                echo "<br />";

                $metody = $reflection->getMethods();
                foreach($metody as $key => $value){
                    echo "<br />". $value;
                }

                echo "<br />";

                $vars = $reflection->getProperties();
                foreach($vars as $key => $value){
                    echo "<br />". $value;
                }
                echo "</pre>";
            }

To show you how it works I will create now some random example class. Lets create class called Person and lets place some release notes just above the class declaration:

        /**
         * DocNotes -  This is description of this class if given else it will display false
         */
        class Person{
            private $name;
            private $dob;
            private $height;
            private $weight;
            private static $num;

            function __construct($dbo, $height, $weight, $name) {
                $this->dob = $dbo;
                $this->height = (integer)$height;
                $this->weight = (integer)$weight;
                $this->name = $name;
                self::$num++;

            }
            public function eat($var="", $sar=""){
                echo $var;
            }
            public function potrzeba($var =""){
                return $var;
            }
        }

Now lets create a instance of a Person and wrap it with our function.

    $Wictor = new Person("27.04.1987", 170, 70, "Wictor");
    TO($Wictor);

This will output information about the class name, parameters and methods including encapsulation information and the number of parameters, names of parameters for each method, method location and lines of code where it exists. See the output below:

CLASS NAME = Person
/**
             * DocNotes -  This is description of this class if given else it will display false
             */

I prefer using braces. Adding braces makes it easier to read and modify.

Here are some links for the use of braces:

• Prefer Multiline if

• Omitting Braces: Not Just A Matter Of Style

• Stack Overflow

in the latest packages you can also use

vp.getCurrentItem()

or

vp is the viewPager ,

pageListener = new PageListener();
vp.setOnPageChangeListener(pageListener);

you have to put a page change listener for your viewPager. There is no method on viewPager to get the current page.

private int currentPage;

    private static class PageListener extends SimpleOnPageChangeListener{
            public void onPageSelected(int position) {
                Log.i(TAG, "page selected " + position);
                   currentPage = position;
        }
    }

TL;DR: Yes, the only Swift language implementation is slow, right now. If you need fast, numeric (and other types of code, presumably) code, just go with another one. In the future, you should re-evaluate your choice. It might be good enough for most application code that is written at a higher level, though.

From what I'm seeing in SIL and LLVM IR, it seems like they need a bunch of optimizations for removing retains and releases, which might be implemented in Clang (for Objective-C), but they haven't ported them yet. That's the theory I'm going with (for now… I still need to confirm that Clang does something about it), since a profiler run on the last test-case of this question yields this “pretty” result:

As was said by many others, -Ofast is totally unsafe and changes language semantics. For me, it's at the “If you're going to use that, just use another language” stage. I'll re-evaluate that choice later, if it changes.

-O3 gets us a bunch of swift_retain and swift_release calls that, honestly, don't look like they should be there for this example. The optimizer should have elided (most of) them AFAICT, since it knows most of the information about the array, and knows that it has (at least) a strong reference to it.

It shouldn't emit more retains when it's not even calling functions which might release the objects. I don't think an array constructor can return an array which is smaller than what was asked for, which means that a lot of checks that were emitted are useless. It also knows that the integer will never be above 10k, so the overflow checks can be optimized (not because of -Ofast weirdness, but because of the semantics of the language (nothing else is changing that var nor can access it, and adding up to 10k is safe for the type Int).

The compiler might not be able to unbox the array or the array elements, though, since they're getting passed to sort(), which is an external function and has to get the arguments it's expecting. This will make us have to use the Int values indirectly, which would make it go a bit slower. This could change if the sort() generic function (not in the multi-method way) was available to the compiler and got inlined.

This is a very new (publicly) language, and it is going through what I assume are lots of changes, since there are people (heavily) involved with the Swift language asking for feedback and they all say the language isn't finished and will change.

Code used:

import Cocoa

let swift_start = NSDate.timeIntervalSinceReferenceDate();
let n: Int = 10000
let x = Int[](count: n, repeatedValue: 1)
for i in 0..n {
    for j in 0..n {
        let tmp: Int = x[j]
        x[i] = tmp
    }
}
let y: Int[] = sort(x)
let swift_stop = NSDate.timeIntervalSinceReferenceDate();

println("\(swift_stop - swift_start)s")

P.S: I'm not an expert on Objective-C nor all the facilities from Cocoa, Objective-C, or the Swift runtimes. I might also be assuming some things that I didn't write.

Everything is fine, just one mistake is there. Change this:

$query = mysql_query("SELECT username FROM Users WHERE username=$username", $con);
$query = mysql_query("SELECT Count(*) FROM Users WHERE username=$username, $con");

if (mysql_num_rows($query) != 0)
{
    echo "Username already exists";
}
else
{
  ...
}

SELECT * will not work, use with SELECT COUNT(*).

In MySQL if You don't want to change the collation and want to perform case sensitive search then just use binary keyword like this:

SELECT * FROM table_name WHERE binary username=@search_parameter and binary password=@search_parameter

In my version of SQL I can't use REPLICATE. SO I did this:

SELECT 
    CONCAT(REPEAT('0', 6-LENGTH(emplyeeID)), emplyeeID) AS emplyeeID 
FROM 
    dbo.RequestItems`

Set the minOccurs attribute to 0 in the schema like so:

<?xml version="1.0"?>
  <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:element name="request">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="amenity">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="description" type="xs:string" minOccurs="0" />
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element> </xs:schema>

I found AlecRust's solution quite helpful, but I add something to resolve one problem: When you click on a single accordion to expand it and then you click on the button to expand, they will all be opened. But, if you click again on the button to collapse, the single accordion expand before won't be collapse.

I've used imageButton, but you can also apply that logic to buttons.

/*** Expand all ***/
$(".expandAll").click(function (event) {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').next().slideDown();

    return false;
});

/*** Collapse all ***/
$(".collapseAll").click(function (event) {
    $('.accordion').accordion({
        collapsible: true,
        active: false
    });

    $('.accordion .ui-accordion-header').next().slideUp();

    return false;
});

Also, if you have accordions inside an accordion and you want to expand all only on that second level, you can add a query:

/*** Expand all Second Level ***/
$(".expandAll").click(function (event) {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').nextAll(':has(.accordion .ui-accordion-header)').slideDown();

    return false;
});

Using naked excepts is not a good practice because you usually catch more than you bargain for.

I would suggest modifying the except to catch ONLY the exception that you would like to handle. I don't think that raising it has the desired effect, because when you go to instantiate TheThread in the outer try, if it raises an exception, the assignment is never going to happen.

Instead you might want to just alert on it and move on, such as:

def run(self):
    try:
       shul.copytree(self.sourceFolder, self.destFolder)
    except OSError, err:
       print err

Then when that exception is caught, you can handle it there. Then when the outer try catches an exception from TheThread, you know it won't be the one you already handled, and will help you isolate your process flow.

If you are interested in now only, then simply use:

Date d = new Date();

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

There are couple of ways of including your python script with name abc.py

1. e.g. if your file is called abc.py (import abc) Limitation is that your file should be present in the same location where your calling python script is.

import abc

2. e.g. if your python file is inside the Windows folder. Windows folder is present at the same location where your calling python script is.

from folder import abc

3. Incase abc.py script is available insider internal_folder which is present inside folder

from folder.internal_folder import abc

4. As answered by James above, in case your file is at some fixed location

import os
import sys
scriptpath = "../Test/MyModule.py"
sys.path.append(os.path.abspath(scriptpath))
import MyModule

In case your python script gets updated and you don't want to upload - use these statements for auto refresh. Bonus :)

%load_ext autoreload 
%autoreload 2

java.time

With the Java 8 Date and Time API you can use the LocalDate class.

LocalDate.now().plusDays(nrOfDays)

See the Oracle Tutorial.

You have to use UPDATE instead of INSERT:

• UPDATE Syntax

For Example:

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

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

In case it's useful, here's a C++ version of the Java snippet posted by Ribo:

{
    // decompressXML -- Parse the 'compressed' binary form of Android XML docs 
    // such as for AndroidManifest.xml in .apk files
    enum

    //   4th word is: Number of strings in string table
    // WARNING: Sometime I indiscriminently display or refer to word in

    // StringTable, each string is represented with a 16 bit little endian 
    // character count, followed by that number of 16 bit (LE) (Unicode) chars.
    int stOff = sitOff + numbStrings*4;  // StringTable follows StrIndexTable

Your problem might also be inside your Java code setting, I mean, if your program somehow could not realize the main class/main file (entry point), it will not launch the the program/.jar (specially application built on IDE's). To solve that on an IDE :

• Right Click the project > Properties > Run > Browse Main Class > OK.
• Clean and Rebuild

Try running it now. Hope it helps

You could add an event handler to your input like so:

document.getElementById('addLinks').onkeypress=function(e){
    if(e.keyCode==13){
        document.getElementById('linkadd').click();
    }
}

What are you trying to achieve? There is absolutely no reason to ever do what you describe, and there is likely a much better solution to the problem you're trying to solve..

The most obvious alternative to what you request is a dictionary. For example:

>>> my_data = {'var': 'something'}
>>> my_data['something_else'] = 'something'
>>> print my_data.keys()
['var', 'something_else']
>>> print my_data['var']
something

Mostly as a.. challenge, I implemented your desired output. Do not use this code, please!

#!/usr/bin/env python2.6
class NewLocals:
    """Please don't ever use this code.."""
    def __init__(self, initial_locals):
        self.prev_locals = list(initial_locals.keys())

    def show_new(self, new_locals):
        output = ", ".join(list(set(new_locals) - set(self.prev_locals)))
        self.prev_locals = list(new_locals.keys())
        return output
# Set up
eww = None
eww = NewLocals(locals())

# "Working" requested code

var = {}

print eww.show_new(locals())  # Outputs: var

something_else = 3
print eww.show_new(locals()) # Outputs: something_else

# Further testing

another_variable = 4
and_a_final_one = 5

print eww.show_new(locals()) # Outputs: another_variable, and_a_final_one

Check the HTTP headers that chrome is sending with the request (Using browser extension or proxy) then try sending the same headers with CURL - Possibly one at a time till you figure out which header(s) makes the request work.

curl -A [user-agent] -H [headers] "http://something.com/api"

import os

path = chap_name

if not os.path.exists(path):
    os.makedirs(path)

filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
    temp_file.write(buff)

Key point is to use os.makedirs in place of os.mkdir. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html

Open the file in binary mode as you are storing binary (jpeg) data.

In response to Edit 2, if img_alt sometimes has '/' in it:

img_alt = os.path.basename(img_alt)

Always use latest SDK version to build:

compileSdkVersion 23

It does not affect runtime behavior, but give you latest programming features.

Remember that

log(n!) = log(1) + log(2) + ... + log(n-1) + log(n)

You can get the upper bound by

log(1) + log(2) + ... + log(n) <= log(n) + log(n) + ... + log(n)
                                = n*log(n)

And you can get the lower bound by doing a similar thing after throwing away the first half of the sum:

log(1) + ... + log(n/2) + ... + log(n) >= log(n/2) + ... + log(n) 
                                       = log(n/2) + log(n/2+1) + ... + log(n-1) + log(n)
                                       >= log(n/2) + ... + log(n/2)
                                        = n/2 * log(n/2) 

This solution reads a single character and calls a function on a yes response.

read -p "Are you sure? (y/n) " -n 1
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
    do_something      
fi

This is simple example by using ternary operator to set selected=selected

<?php $plan = array('1' => 'Green','2'=>'Red' ); ?>
<select class="form-control" title="Choose Plan">
<?php foreach ($plan as $key => $value) { ?>
  <option value="<?php echo $key;?>" <?php echo ($key ==  '2') ? ' selected="selected"' : '';?>><?php echo $value;?></option>
<?php } ?>
</select>

Honestly? I've never found a use for staticmethod or classmethod. I've yet to see an operation that can't be done using a global function or an instance method.

It would be different if python used private and protected members more like Java does. In Java, I need a static method to be able to access an instance's private members to do stuff. In Python, that's rarely necessary.

Usually, I see people using staticmethods and classmethods when all they really need to do is use python's module-level namespaces better.

C++ is a standardized language. Visual C++ is a product that more or less implements that standard. You can write portable C++ using Visual C++, but you can also use Microsoft-only extensions that destroy your portability but enhance your productivity. This is a trade-off. You have to decide what appeals most to you.

I've maintained big desktop apps that were written in Visual C++, so that is perfectly feasible. From what I know of Visual Basic, the main advantage seems to be that the first part of the development cycle may be done faster than when using Visual C++, but as the complexity of a project increases, C++ programs tend to be more maintainable (If the programmers are striving for maintainability, that is).

To delete multiple services in Powershell 5.0, since remove service does not exist in this version

Run the below command

Get-Service -Displayname "*ServiceName*" | ForEach-object{ cmd /c  sc delete $_.Name}

If you want the exact numbers, use the following ruby script. You need Ruby and RubyGems.

Install following Gems:

$> gem install dbi
$> gem install dbd-mysql

File: count_table_records.rb

require 'rubygems'
require 'dbi'

db_handler = DBI.connect('DBI:Mysql:database_name:localhost', 'username', 'password')

# Collect all Tables
sql_1 = db_handler.prepare('SHOW tables;')
sql_1.execute
tables = sql_1.map { |row| row[0]}
sql_1.finish

tables.each do |table_name|
  sql_2 = db_handler.prepare("SELECT count(*) FROM #{table_name};")
  sql_2.execute
  sql_2.each do |row|
    puts "Table #{table_name} has #{row[0]} rows."
  end
  sql_2.finish
end

db_handler.disconnect

Go back to the command-line:

$> ruby count_table_records.rb

Output:

Table users has 7328974 rows.

Pass your arguments in constructor itself.

Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe","param1","param2").start();

DELETE

The DELETE command is used to remove rows from a table. A WHERE clause can be used to only remove some rows. If no WHERE condition is specified, all rows will be removed. After performing a DELETE operation you need to COMMIT or ROLLBACK the transaction to make the change permanent or to undo it.

TRUNCATE

TRUNCATE removes all rows from a table. The operation cannot be rolled back ... As such, TRUCATE is faster and doesn't use as much undo space as a DELETE.

Too bad Oracle has limitations like these. Sure, the result for a column not in the GROUP BY would be random, but sometimes you want that. Silly Oracle, you can do this in MySQL/MSSQL.

BUT there is a work around for Oracle:

While the following line does not work

SELECT unique_id_col, COUNT(1) AS cnt FROM yourTable GROUP BY col_A;

You can trick Oracle with some 0's like the following, to keep your column in scope, but not group by it (assuming these are numbers, otherwise use CONCAT)

SELECT MAX(unique_id_col) AS unique_id_col, COUNT(1) AS cnt 
FROM yourTable GROUP BY col_A, (unique_id_col*0 + col_A);

If you want to print XML directly onto the screen you can use TransformerFactory

URL url = new URL(urlString);
URLConnection conn = url.openConnection();

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(conn.getInputStream());

TransformerFactory transformerFactory= TransformerFactory.newInstance();
Transformer xform = transformerFactory.newTransformer();

// that’s the default xform; use a stylesheet to get a real one
xform.transform(new DOMSource(doc), new StreamResult(System.out));

In Twig:

{% for l in locations %}

<tr>
    <td>
        <input type="checkbox" class="filled-in" id="filled-in-box-{{ l.idLocation }}" />
        <label for="filled-in-box-{{ l.idLocation }}"></label>
    </td>
    <td>{{ l.loc }}</td>
    <td>{{ l.mun }}</td>
    <td>{{ l.pro }}</td>
    <td>{{ l.cou }}</td>
    {#<td>
        {% if l.active == 1  %}
            <span class="fa fa-check"></span>
        {% else %}
            <span class="fa fa-close"></span>
        {% endif %}
    </td>#}
    <td><a href="{{ url('admin_edit_location',{'id': l.idLocation}) }}" class="db-list-edit"><span class="fa fa-pencil-square-o"></span></a>
    </td>
</tr>{% endfor %}

The route admin_edit_location:

admin_edit_location:
  path: /edit_location/{id}
  defaults: { _controller: "AppBundle:Admin:editLocation" }
  methods: GET

And the controller

public function editLocationAction($id){
    // use $id 

    $em = $this->getDoctrine()->getManager();
    $location = $em->getRepository('BackendBundle:locations')->findOneBy(array(
    'id'    => $id
    ));
}

To complement the preexisting, helpful answers with guidance of when to use which approach and a performance comparison.

• Outside of a pipeline^[1], use (PSv3+):

  $objects.Name

  as demonstrated in rageandqq's answer, which is both syntactically simpler and much faster.

  • Accessing a property at the collection level to get its members' values as an array is called member enumeration and is a PSv3+ feature.

  • Alternatively, in PSv2, use the foreach statement, whose output you can also assign directly to a variable:

    $results = foreach ($obj in $objects) { $obj.Name }

  • If collecting all output from a (pipeline) command in memory first is feasible, you can also combine pipelines with member enumeration; e.g.:

     (Get-ChildItem -File | Where-Object Length -lt 1gb).Name
    

  • Tradeoffs:

    • Both the input collection and output array must fit into memory as a whole.
    • If the input collection is itself the result of a command (pipeline) (e.g., (Get-ChildItem).Name), that command must first run to completion before the resulting array's elements can be accessed.

• In a pipeline, in case you must pass the results to another command, notably if the original input doesn't fit into memory as a whole, use:

  $objects | Select-Object -ExpandProperty Name

  • The need for -ExpandProperty is explained in Scott Saad's answer (you need it to get only the property value).
  • You get the usual pipeline benefits of the pipeline's streaming behavior, i.e. one-by-one object processing, which typically produces output right away and keeps memory use constant (unless you ultimately collect the results in memory anyway).
  • Tradeoff:
    • Use of the pipeline is comparatively slow.

For small input collections (arrays), you probably won't notice the difference, and, especially on the command line, sometimes being able to type the command easily is more important.

Here is an easy-to-type alternative, which, however is the slowest approach; it uses simplified ForEach-Object syntax called an operation statement (again, PSv3+): ; e.g., the following PSv3+ solution is easy to append to an existing command:

$objects | % Name      # short for: $objects | ForEach-Object -Process { $_.Name }

The PSv4+ .ForEach() array method, more comprehensively discussed in this article, is yet another, well-performing alternative, but note that it requires collecting all input in memory first, just like member enumeration:

# By property name (string):
$objects.ForEach('Name')

# By script block (more flexibility; like ForEach-Object)
$objects.ForEach({ $_.Name })

• This approach is similar to member enumeration, with the same tradeoffs, except that pipeline logic is not applied; it is marginally slower than member enumeration, though still noticeably faster than the pipeline.

• For extracting a single property value by name (string argument), this solution is on par with member enumeration (though the latter is syntactically simpler).

• The script-block variant ({ ... }) allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).

Note: The .ForEach() array method, like its .Where() sibling (the in-memory equivalent of Where-Object), always returns a collection (an instance of [System.Collections.ObjectModel.Collection[psobject]]), even if only one output object is produced.
By contrast, member enumeration, Select-Object, ForEach-Object and Where-Object return a single output object as-is, without wrapping it in a collection (array).

Comparing the performance of the various approaches

Here are sample timings for the various approaches, based on an input collection of 10,000 objects, averaged across 10 runs; the absolute numbers aren't important and vary based on many factors, but it should give you a sense of relative performance (the timings come from a single-core Windows 10 VM:

Important

• The relative performance varies based on whether the input objects are instances of regular .NET Types (e.g., as output by Get-ChildItem) or [pscustomobject] instances (e.g., as output by Convert-FromCsv).
  The reason is that [pscustomobject] properties are dynamically managed by PowerShell, and it can access them more quickly than the regular properties of a (statically defined) regular .NET type. Both scenarios are covered below.

• The tests use already-in-memory-in-full collections as input, so as to focus on the pure property extraction performance. With a streaming cmdlet / function call as the input, performance differences will generally be much less pronounced, as the time spent inside that call may account for the majority of the time spent.

• For brevity, alias % is used for the ForEach-Object cmdlet.

General conclusions, applicable to both regular .NET type and [pscustomobject] input:

• The member-enumeration ($collection.Name) and foreach ($obj in $collection) solutions are by far the fastest, by a factor of 10 or more faster than the fastest pipeline-based solution.

• Surprisingly, % Name performs much worse than % { $_.Name } - see this GitHub issue.

• PowerShell Core consistently outperforms Windows Powershell here.

Conclusions:

• In PowerShell Core, .ForEach('Name') clearly outperforms .ForEach({ $_.Name }). In Windows PowerShell, curiously, the latter is faster, albeit only marginally so.

Conclusions:

• Note how with [pscustomobject] input .ForEach('Name') by far outperforms the script-block based variant, .ForEach({ $_.Name }).

• Similarly, [pscustomobject] input makes the pipeline-based Select-Object -ExpandProperty Name faster, in Windows PowerShell virtually on par with .ForEach({ $_.Name }), but in PowerShell Core still about 50% slower.

• In short: With the odd exception of % Name, with [pscustomobject] the string-based methods of referencing the properties outperform the scriptblock-based ones.

$runs  = 10  # number of runs to average 

# Note: Using [pscustomobject] instances rather than instances of 
#       regular .NET types changes the performance characteristics.
# Set this to $true to test with [pscustomobject] instances below.
$useCustomObjectInput = $false

# Create sample input objects.
if ($useCustomObjectInput) {
  # Use [pscustomobject] instances.
  $objects = 1..$count | % { [pscustomobject] @{ Name = "$foobar_$_"; Other1 = 1; Other2 = 2; Other3 = 3; Other4 = 4 } }

^{[1] Technically, even a command without |, the pipeline operator, uses a pipeline behind the scenes, but for the purpose of this discussion using the pipeline refers only to commands that do use | and therefore involve multiple commands connected by a pipeline.}

This would become a bit more clear if you add a line to both examples:

var result = database.query("SELECT * FROM hugetable");
console.log(result.length);
console.log("Hello World");

The second one:

database.query("SELECT * FROM hugetable", function(rows) {
   var result = rows;
   console.log(result.length);
});
console.log("Hello World");

Try running these, and you’ll notice that the first (synchronous) example, the result.length will be printed out BEFORE the 'Hello World' line. In the second (the asynchronous) example, the result.length will (most likely) be printed AFTER the "Hello World" line.

That's because in the second example, the database.query is run asynchronously in the background, and the script continues straightaway with the "Hello World". The console.log(result.length) is only executed when the database query has completed.

$_SERVER['REQUEST_URI']

For more details on what info is available in the $_SERVER array, see the PHP manual page for it.

If you also need the query string (the bit after the ? in a URL), that part is in this variable:

$_SERVER['QUERY_STRING']

To use foreach would require you have an array that contains every row from the query result. Some DB libraries for PHP provide a fetch_all function that provides an appropriate array but I could not find one for mysql (however the mysqli extension does) . You could of course write your own, like so

function mysql_fetch_all($result) {
   $rows = array();
   while ($row = mysql_fetch_array($result)) {
     $rows[] = $row;
   }
   return $rows;
}

However I must echo the "why?" Using this function you are creating two loops instead of one, and requring the entire result set be loaded in to memory. For sufficiently large result sets, this could become a serious performance drag. And for what?

foreach (mysql_fetch_all($result) as $row)

vs

while ($row = mysql_fetch_array($result))

while is just as concise and IMO more readable.

EDIT There is another option, but it is pretty absurd. You could use the Iterator Interface

class MysqlResult implements Iterator {
  private $rownum = 0;
  private $numrows = 0;
  private $result;

  public function __construct($result) {
    $this->result = $result;
    $this->numrows = mysql_num_rows($result);
  }

  public function rewind() {
    $this->rownum = 0;
  }

  public function current() {
    mysql_data_seek($this->result, $this->rownum);
    return mysql_fetch_array($this->result);
  }

  public function key() {
    return $this->rownum;
  }

  public function next() {
    $this->rownum++;
  }

  public function valid() {
    return $this->rownum < $this->numrows ? true : false;
  }
}

$rows = new MysqlResult(mysql_query($query_select));

foreach ($rows as $row) {
  //code...
}

In this case, the MysqlResult instance fetches rows only on request just like with while, but wraps it in a nice foreach-able package. While you've saved yourself a loop, you've added the overhead of class instantiation and a boat load of function calls, not to mention a good deal of added code complexity.

But you asked if it could be done without using while (or for I imagine). Well it can be done, just like that. Whether it should be done is up to you.

function InvalidValueError(value, type) {
    this.message = "Expected `" + type.name + "`: " + value;
    var error = new Error(this.message);
    this.stack = error.stack;
}
InvalidValueError.prototype = new Error();
InvalidValueError.prototype.name = InvalidValueError.name;
InvalidValueError.prototype.constructor = InvalidValueError;

I tried your code, you didn't assign/bind a value to your formControlName.

In HTML file:

<form [formGroup]="form">
   <label>
     <input type="radio" value="Male" formControlName="gender">
       <span>male</span>
   </label>
   <label>
     <input type="radio" value="Female" formControlName="gender">
       <span>female</span>
   </label>
</form>

In the TS file:

  form: FormGroup;
  constructor(fb: FormBuilder) {
    this.name = 'Angular2'
    this.form = fb.group({
      gender: ['', Validators.required]
    });
  }

Make sure you use Reactive form properly: [formGroup]="form" and you don't need the name attribute.

In my sample. words male and female in span tags are the values display along the radio button and Male and Female values are bind to formControlName

See the screenshot:

To make it shorter:

<form [formGroup]="form">
  <input type="radio" value='Male' formControlName="gender" >Male
  <input type="radio" value='Female' formControlName="gender">Female
</form>

Hope it helps:)

You can delete the archive files and executable binaries that go install (or go get) produces for a package with go clean -i importpath.... These normally reside under $GOPATH/pkg and $GOPATH/bin, respectively.

Be sure to include ... on the importpath, since it appears that, if a package includes an executable, go clean -i will only remove that and not archive files for subpackages, like gore/gocode in the example below.

Source code then needs to be removed manually from $GOPATH/src.

go clean has an -n flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean). It also has a tempting -r flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!

A complete example, which you could base a script on if you like:

$ go get -u github.com/motemen/gore

$ which gore
/Users/ches/src/go/bin/gore

$ go clean -i -n github.com/motemen/gore...
cd /Users/ches/src/go/src/github.com/motemen/gore
rm -f gore gore.exe gore.test gore.test.exe commands commands.exe commands_test commands_test.exe complete complete.exe complete_test complete_test.exe debug debug.exe helpers_test helpers_test.exe liner liner.exe log log.exe main main.exe node node.exe node_test node_test.exe quickfix quickfix.exe session_test session_test.exe terminal_unix terminal_unix.exe terminal_windows terminal_windows.exe utils utils.exe
rm -f /Users/ches/src/go/bin/gore
cd /Users/ches/src/go/src/github.com/motemen/gore/gocode
rm -f gocode.test gocode.test.exe
rm -f /Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore/gocode.a

$ go clean -i github.com/motemen/gore...

$ which gore

$ tree $GOPATH/pkg/darwin_amd64/github.com/motemen/gore
/Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore

0 directories, 0 files

# If that empty directory really bugs you...
$ rmdir $GOPATH/pkg/darwin_amd64/github.com/motemen/gore

$ rm -rf $GOPATH/src/github.com/motemen/gore

Note that this information is based on the go tool in Go version 1.5.1.

In General...

The method exposed by sykora is the best option in this case. But sometimes is not the easiest and it's not a general method. For a general method use git cherry-pick:

To achieve what OP wants, its a 2-step process:

Step 1 - Note which commits from master you want on a newbranch

Execute

git checkout master
git log

Note the hashes of (say 3) commits you want on newbranch. Here I shall use:
C commit: 9aa1233
D commit: 453ac3d
E commit: 612ecb3

Note: You can use the first seven characters or the whole commit hash

Step 2 - Put them on the newbranch

git checkout newbranch
git cherry-pick 612ecb3
git cherry-pick 453ac3d
git cherry-pick 9aa1233

OR (on Git 1.7.2+, use ranges)

git checkout newbranch
git cherry-pick 612ecb3~1..9aa1233

git cherry-pick applies those three commits to newbranch.

Read the image, convert it to byte[], then return a File() with a content type.

public ActionResult ImageResult(Image image, ImageFormat format, string contentType) {
  using (var stream = new MemoryStream())
    {
      image.Save(stream, format);
      return File(stream.ToArray(), contentType);
    }
  }
}

Here are the usings:

using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using Microsoft.AspNetCore.Mvc;

You need to set the backgroundColor of the cell's contentView to your color. If you use accessories (such as disclosure arrows, etc), they'll show up as white, so you may need to roll custom versions of those.

You can create an ExtensionMethod to do that!

public static class StringExtension
{
  public static string Repeat(this string str, int count)
  {
    string ret = "";

    for (var x = 0; x < count; x++)
    {
      ret += str;
    }

    return ret;
  }
}

Or using @Dan Tao solution:

public static class StringExtension
{
  public static string Repeat(this string str, int count)
  {
    if (count == 0)
      return "";

    return string.Concat(Enumerable.Repeat(indent, N))
  }
}

let formFields     = form.querySelectorAll(`input:not([type='hidden']), select`)

ES6 version that has the advantage of ignoring the hidden fields if that is what you want

I can't answer your original question but I would like to offer you some advice -- don't depend on the JVM's default encoding. It's always best to explicitly specify the desired encoding (i.e. "UTF-8") in your code. That way, you know it will work even across different systems and JVM configurations.

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).

This error occurs because the transaction log becomes full due to LOG_BACKUP. Therefore, you can’t perform any action on this database, and In this case, the SQL Server Database Engine will raise a 9002 error.

To solve this issue you should do the following

• Take a Full database backup.
• Shrink the log file to reduce the physical file size.
• Create a LOG_BACKUP.
• Create a LOG_BACKUP Maintenance Plan to take backup logs frequently.

I wrote an article with all details regarding this error and how to solve it at The transaction log for database ‘SharePoint_Config’ is full due to LOG_BACKUP

The direct use of EDATE(Start_date, months) do the job of ADDDate. Example:

Consider A1 = 20/08/2012 and A2 = 3

=edate(A1; A2)

Would calculate 20/11/2012

PS: dd/mm/yyyy format in my example

try to SendKeys instead of picking the date

driver.FindElement(yourBy).SendKeys(yourDateTime.ToString("ddd, dd.MM.yyyy",CultureInfo.CreateSpecificCulture("en-US")));

If it does not work, try to send native 'tab'

element.SendKeys(OpenQA.Selenium.Keys.Tab);

When creating a project from a sample,while not importing the existing project is good (prevents clashes with gradle, .idea, .iml, build, jars and apks, i.e. all unnecessary build-generated files), after creating a new project, copying and pasting all relevant resources, I'd recommend :

checking packages and imports from packages within the project {AndroidManifest declaration and all imports in java classes}, all resources (drawable, mip-map, layouts and menus & your build.gradle (a sample of build.gradle to use with the latest sdk can be provided on request)) to see if they are there & if declared strings and ids actually exist and have been used, after which your only error should be the question asked:

Bulid->Clean Project

Tools->Android->Sync Project with Gradle Files

File->Invalidate Caches and Restart

In worst cases restarting your machine helps.

The above should work. Feel free to ask questions if necessary, i.e. post comments.

On my iSeries I have to run this command from iNavigator:

You cannot close a window with javascript that you did not open. It will not work in chrome or firefox.

See https://stackoverflow.com/a/19768082/2623781 for more information.

The SET clause should come after the table specification.

UPDATE business AS b
INNER JOIN business_geocode g ON b.business_id = g.business_id
SET b.mapx = g.latitude,
  b.mapy = g.longitude
WHERE  (b.mapx = '' or b.mapx = 0) and
  g.latitude > 0

You could use Homebrew.

Then just run:

You are confusing quantmod's 'symbol' (a term relating to a code for some financial thingamuwot) with R's 'symbol', which is a 'type' in R.

You've said:

I have a character vector of stock symbols that I pass to quantmod::getSymbols() and the function returns the symbol to the environment without the quotes

Well almost. What it does is create objects with those names in the specified environment. What I think you want to do is to get things out of an environment by name. And for that you need 'get'. Here's how, example code, working in the default environment:

getSymbols('F',src='yahoo',return.class='ts') [1] "F"

so you have a vector of characters of the things you want:

> z="F"
> z
[1] "F"

and then the magic:

> summary(get(z))
     F.Open           F.High           F.Low           F.Close

 Max.   :18.810   Max.   :18.970   Max.   :18.610   Max.   :18.790  

and if you don't believe me:

> identical(F,get(z))
[1] TRUE

Using header file stdio.h you can easily do it as usual like c. before using %.2lf(set a specific number after % specifier.) using printf().

It simply printf specific digits after decimal point.

#include <stdio.h>
#include <iostream>
using namespace std;
int main()
{
   double total=100;
   printf("%.2lf",total);//this prints 100.00 like as C
}

This error is basically saying that maven couldn't read a certain dependency from local repository. It might happend because a jar file didn't get downloaded correctly. So, go to your maven local repository and make sure there isn't any .lastUpdated extension file.

You'll want something like this, taken from http://www.howtocreate.co.uk/tutorials/javascript/browserwindow

function alertSize() {
  var myWidth = 0, myHeight = 0;
  if( typeof( window.innerWidth ) == 'number' ) {
    //Non-IE
    myWidth = window.innerWidth;
    myHeight = window.innerHeight;
  } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
    //IE 6+ in 'standards compliant mode'
    myWidth = document.documentElement.clientWidth;
    myHeight = document.documentElement.clientHeight;
  } else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
    //IE 4 compatible
    myWidth = document.body.clientWidth;
    myHeight = document.body.clientHeight;
  }
  window.alert( 'Width = ' + myWidth );
  window.alert( 'Height = ' + myHeight );
}

So that's innerHeight for modern browsers, documentElement.clientHeight for IE, body.clientHeight for deprecated/quirks.

Just truncate the digits:

function truncDigits(inputNumber, digits) {
  const fact = 10 ** digits;
  return Math.floor(inputNumber * fact) / fact;

Rebase and Cherry-pick is the only way you can keep clean commit history. Avoid using merge and avoid creating merge conflict. If you are using gerrit set one project to Merge if necessary and one project to cherry-pick mode and try yourself.

Case 1 should have worked. I don't see anything wrong. There may be some other problems. I would suggest a clean build.

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

Based on average distance for degress in the Earth.

1° = 111km;

Converting this for radians and dividing for meters, take's a magic number for the RAD, in meters: 0.000008998719243599958;

then:

const RAD = 0.000008998719243599958;
Math.sqrt(Math.pow(lat1 - lat2, 2) + Math.pow(long1 - long2, 2)) / RAD;

Getting java.nio.file.AccessDeniedException when trying to write to a folder

Unobviously, Comodo antivirus has an "Auto-Containment" setting that can cause this exact error as well. (e.g. the user can write to a location, but the java.exe and javaw.exe processes cannot).

In this edge-case scenario, adding an exception for the process and/or folder should help.

Temporarily disabling the antivirus feature will help understand if Comodo AV is the culprit.

I post this not because I use or prefer Comodo, but because it's a tremendously unobvious symptom to an otherwise functioning Java application and can cost many hours of troubleshooting file permissions that are sane and correct, but being blocked by a 3rd-party application.

Let me tell you an annoying thing that happened with the N' prefix - I wasn't able to fix it for two days.

My database collation is SQL_Latin1_General_CP1_CI_AS.

It has a table with a column called MyCol1. It is an Nvarchar

This query fails to match Exact Value That Exists.

SELECT TOP 1 * FROM myTable1 WHERE  MyCol1 = 'ESKI'  

// 0 result

using prefix N'' fixes it

SELECT TOP 1 * FROM myTable1 WHERE  MyCol1 = N'ESKI'  

// 1 result - found!!!!

Why? Because latin1_general doesn't have big dotted I that's why it fails I suppose.

I personally would just use the JavaScript code to switch between 2 classes.

Have the CSS outline everything you need on your div MINUS the background rule, then add two classes (e.g: expanded & collapsed) as rules each with the correct background image (or background position if using a sprite).

CSS with different images

.div {
    /* button size etc properties */
}

.expanded {background: url(img/x.gif) no-repeat left top;}
.collapsed {background: url(img/y.gif) no-repeat left top;}

Or CSS with image sprite

.div {
    background: url(img/sprite.gif) no-repeat left top;
    /* Other styles */
}

.expanded {background-position: left bottom;}

Then...

JavaScript code with images

$(function){
    $('#button').click(function(){
        if($(this).hasClass('expanded'))
        {
            $(this).addClass('collapsed').removeClass('expanded');
        }
        else
        {
            $(this).addClass('expanded').removeClass('collapsed');
        }
    });
}

JavaScript with sprite

Note: the elegant toggleClass does not work in Internet Explorer 6, but the below addClass/removeClass method will work fine in this situation as well

The most elegant solution (unfortunately not Internet Explorer 6 friendly)

$(function){
        $('#button').click(function(){
            $(this).toggleClass('expanded');
        });
    }

$(function){
        $('#button').click(function(){
            if($(this).hasClass('expanded'))
            {
                $(this).removeClass('expanded');
            }
            else
            {
                $(this).addClass('expanded');
            }
        });
    }

As far as I know this method will work accross browsers, and I would feel much more comfortable playing with CSS and classes than with URL changes in the script.

I've modified andrewz' post to make it compatible with Swift 2.0 (and maybe Swift 3.0). In my humble opinion, this extension is easier to understand and similar to what is available in other languages (like PHP).

extension String {

    func length() -> Int {
        return self.lengthOfBytesUsingEncoding(NSUTF16StringEncoding)
    }
    func substring(from:Int = 0, to:Int = -1) -> String {
       var nto=to
        if nto < 0 {
            nto = self.length() + nto
        }
        return self.substringWithRange(Range<String.Index>(
           start:self.startIndex.advancedBy(from),
           end:self.startIndex.advancedBy(nto+1)))
    }
    func substring(from:Int = 0, length:Int) -> String {
        return self.substringWithRange(Range<String.Index>(
            start:self.startIndex.advancedBy(from),
            end:self.startIndex.advancedBy(from+length)))
    }
}

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

For the text color add:

android:textColor="<hex color>"

For the background color add:

android:background="<hex color>"

From API 21 you can use:

android:backgroundTint="<hex color>"
android:backgroundTintMode="<mode>"

Note: If you're going to work with android/java you really should learn how to google ;)
How to customize different buttons in Android

By far the easiest way to create DOC files on Linux, using PHP is with the Zend Framework component phpLiveDocx.

From the project web site:

"phpLiveDocx allows developers to generate documents by combining structured data from PHP with a template, created in a word processor. The resulting document can be saved as a PDF, DOCX, DOC or RTF file. The concept is the same as with mail-merge."

Well, first you need to select the elements with a function like getElementById.

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];

getElementById only returns one node, but getElementsByClassName returns a node list. Since there is only one element with that class name (as far as I can tell), you can just get the first one (that's what the [0] is for—it's just like an array).

Then, you can change the html with .textContent.

targetDiv.textContent = "Goodbye world!";

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];_x000D_
targetDiv.textContent = "Goodbye world!";

<div id="foo">_x000D_
    <div class="bar">_x000D_
        Hello world!_x000D_
    </div>_x000D_
</div>

this can be achieved with the css calc() operator

@media screen and (min-width: 480px) {
    body {
        background-color: lightgreen;
        zoom:calc(100% / 480);
    }
}

I got the same error using:

<link rel="stylesheet" href="//fonts.googleapis.com/css?family=Source+Sans+Pro:400,400i,700,700i,900,900i" type="text/css" media="all">

But once I added https: in the beginning of the href the error disappeared.

<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Source+Sans+Pro:400,400i,700,700i,900,900i" type="text/css" media="all">
