If You are looking list of methods which respond by an instance (in your case @current_user). According to ruby documentation methods

Returns a list of the names of public and protected methods of obj. This will include all the methods accessible in obj's ancestors. If the optional parameter is false, it returns an array of obj's public and protected singleton methods, the array will not include methods in modules included in obj.

@current_user.methods
@current_user.methods(false) #only public and protected singleton methods and also array will not include methods in modules included in @current_user class or parent of it.

Alternatively, You can also check that a method is callable on an object or not?.

@current_user.respond_to?:your_method_name

If you don't want parent class methods then just subtract the parent class methods from it.

@current_user.methods - @current_user.class.superclass.new.methods #methods that are available to @current_user instance.

You can implement like a below logic. Suppose you want an array of values.

let test = [ {name:'test',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:30},
             {name:'test3',lastname:'kumar',age:47},
             {name:'test',lastname:'kumar',age:28},
             {name:'test4',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:29}]

let result1 = test.map(element => 
              { 
                 if (element.age === 30) 
                 {
                    return element.lastname;
                 }
              }).filter(notUndefined => notUndefined !== undefined);

output : ['kumar','kumar','kumar']

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

SELECT
    IF city='C7'
    THEN city
    ELSE 'somethingelse'
    END as `city`
FROM `table` WHERE `city` = 'c7'

For windows, The Task Manager would definitely show a node process running. Try to kill the process, it will solve the problem.

select max(Emp_Sal) 
from Employee a
where 1 = ( select count(*) 
         from Employee b
         where b.Emp_Sal > a.Emp_Sal)

Yes running man.

A WC product may belong to none, one or more WC categories. Supposing you just want to get one WC category id.

global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
    $product_cat_id = $term->term_id;
    break;
}

Please look into the meta.php file in the "templates/single-product/" folder of the WooCommerce plugin.

<?php echo $product->get_categories( ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', sizeof( get_the_terms( $post->ID, 'product_cat' ) ), 'woocommerce' ) . ' ', '.</span>' ); ?>

The other option for using PHP scripts sans extension is

Options +MultiViews

Or even just following in the directories .htaccess:

DefaultType application/x-httpd-php

The latter allows having all filenames without extension script being treated as PHP scripts. While MultiViews makes the webserver look for alternatives, when just the basename is provided (there's a performance hit with that however).

you can try this code to solve your problem

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true"
   android:drawable="@drawable/login_selected" /> <!-- pressed -->
  <item android:state_focused="true"
   android:drawable="@drawable/login_mouse_over" /> <!-- focused -->
  <item android:drawable="@drawable/login" /> <!-- default -->
</selector>

write this code in your drawable make a new resource and name it what you want and then write the name of this drwable in the button same as we refer to image src in android

I always do: git fetch origin && git checkout --track origin/branch_name

If you have installed nodejs, then you also have npm. Npm comes with node.

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

You have more going on than you said. I ran the following expanded test from your example:

public class test {

    public static void main(String[] args) {
        Object[][] someArray = new Object[5][];
        someArray[0] = new Object[10];
        someArray[1] = null;
        someArray[2] = new Object[1];
        someArray[3] = null;
        someArray[4] = new Object[5];

        for (int i=0; i<=someArray.length-1; i++) {
            if (someArray[i] != null) {
                System.out.println("not null");
            } else {
                System.out.println("null");
            }
        }
    }
}

and got the expected output:

$ /cygdrive/c/Program\ Files/Java/jdk1.6.0_03/bin/java -cp . test
not null
null
not null
null
not null

Are you possibly trying to check the lengths of someArray[index]?

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.

FWIW: I rebuilt a LAMP server from scratch and installed WordPress. I had the same issue after saving my Permalink setting to generate the .htaccess file. Turns out that mod_rewrite was not enabled. I ran across this post on Digital Ocean.
FTA:

First, we need to activate mod_rewrite. It’s available but not enabled with a clean Apache 2 installation.

$ sudo a2enmod rewrite

This will activate the module or alert you that the module is already enabled. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

From the first answer,

"Using Mongoose, a user can define the schema for the documents in a particular collection. It provides a lot of convenience in the creation and management of data in MongoDB."

You can now also define schema with mongoDB native driver using

##For new collection

`db.createCollection("recipes",
    validator: { $jsonSchema: {
         <<Validation Rules>>
        }
    }
)`

##For existing collection

`db.runCommand( {
        collMod: "recipes",
        validator: { $jsonSchema: {
             <<Validation Rules>>
            }
        }
    } )`
    

##full example

`db.createCollection("recipes", {
  validator: {
    $jsonSchema: {
      bsonType: "object",
      required: ["name", "servings", "ingredients"],
      additionalProperties: false,
      properties: {
        _id: {},
        name: {
          bsonType: "string",
          description: "'name' is required and is a string"
        },
        servings: {
          bsonType: ["int", "double"],
          minimum: 0,
          description:
            "'servings' is required and must be an integer with a minimum of zero."
        },
        cooking_method: {
          enum: [
            "broil",
            "grill",
            "roast",
            "bake",
            "saute",

            "steam",
            "braise",
            "stew"
          ],
          description:
            "'cooking_method' is optional but, if used, must be one of the listed options."
        },
        ingredients: {
          bsonType: ["array"],
          minItems: 1,
          maxItems: 50,
          items: {
            bsonType: ["object"],
            required: ["quantity", "measure", "ingredient"],
            additionalProperties: false,
            description: "'ingredients' must contain the stated fields.",
            properties: {
              quantity: {
                bsonType: ["int", "double", "decimal"],
                description:
                  "'quantity' is required and is of double or decimal type"
              },
              measure: {
                enum: ["tsp", "Tbsp", "cup", "ounce", "pound", "each"],
                description:
                  "'measure' is required and can only be one of the given enum values"
              },
              ingredient: {
                bsonType: "string",
                description: "'ingredient' is required and is a string"
              },
              format: {
                bsonType: "string",
                description:
                  "'format' is an optional field of type string, e.g. chopped or diced"
              }
            }
          }
        }
      }
    }
  }
});`

Insert collection Example

`db.recipes.insertOne({
  name: "Chocolate Sponge Cake Filling",
  servings: 4,
  ingredients: [
    {
      quantity: 7,
      measure: "ounce",
      ingredient: "bittersweet chocolate",
      format: "chopped"
    },
    { quantity: 2, measure: "cup", ingredient: "heavy cream" }
  ]
});`

 String str1 = "foo"; 
 String str2 = "foo"; 

Both str1 and str2 belongs to tha same String object, "foo", b'coz Java manages Strings in StringPool, so if a new variable refers to the same String, it doesn't create another one rather assign the same alerady present in StringPool.

 String str1 = new String("foo"); 
 String str2 = new String("foo");

Here both str1 and str2 belongs to different Objects, b'coz new String() forcefully create a new String Object.

Have you looked at this page?

http://www.mongodb.org/display/DOCS/Aggregation#Aggregation-Distinct

That might save you some time?

eg db.addresses.distinct("zip-code");

This is probably due to its lack of connections to the Hive Meta Store,my hive Meta Store is stored in Mysql,so I need to visit Mysql,So I add a dependency in my build.sbt

libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.38"

and the problem is solved!

The typical solution to this is to write your own function to clone an object. If you are able to provide copy constructors and copy assignement operators, this may be as far as you need to go.

class Foo
{ 
public:
  Foo();
  Foo(const Foo& rhs) { /* copy construction from rhs*/ }
  Foo& operator=(const Foo& rhs) {};
};

// ...

Foo orig;
Foo copy = orig;  // clones orig if implemented correctly

Sometimes it is beneficial to provide an explicit clone() method, especially for polymorphic classes.

class Interface
{
public:
  virtual Interface* clone() const = 0;
};

class Foo : public Interface
{
public:
  Interface* clone() const { return new Foo(*this); }
};

class Bar : public Interface
{
public:
  Interface* clone() const { return new Bar(*this); }
};


Interface* my_foo = /* somehow construct either a Foo or a Bar */;
Interface* copy = my_foo->clone();

EDIT: Since Stack has no member variables, there's nothing to do in the copy constructor or copy assignment operator to initialize Stack's members from the so-called "right hand side" (rhs). However, you still need to ensure that any base classes are given the opportunity to initialize their members.

You do this by calling the base class:

Stack(const Stack& rhs) 
: List(rhs)  // calls copy ctor of List class
{
}

Stack& operator=(const Stack& rhs) 
{
  List::operator=(rhs);
  return * this;
};

If you use bootstrap 3 and lesscss you can enable on blur validation with the following less snippet:

:focus ~ .form-control-feedback.glyphicon-ok {
  display:none;
}

:focus ~ .form-control-feedback.glyphicon-remove {
  display:none;
}

.has-feedback > :focus {
  & {
    .form-control-focus();
  }
}

A trivial approach would be to replace

<[^>]*>

with nothing. But depending on how ill-structured your input is that may well fail.

To use zookeeper commands with shell script try

zookeeper/bin/zkCli.sh -server localhost:2181 <<< "ls /brokers/ids" | tail -n 1. The last line usually has the response details

This worked for me:

1. On the Eclipse toolbar, select Window ? Preferences.

2. Set the font size (General ? Appearance ? Colors and Fonts ? Basic ? Text Font):

   

3. Save the preferences.

To open hyperlink in the same tab, use:

$(document).on('click', "a.classname", function() {
    var form = $("<form></form>");
    form.attr(
    {
        id     : "formid",
        action : $(this).attr("href"),
        method : "GET",
    });

    $("body").append(form);
    $("#formid").submit();
    $("#formid").remove();
    return false;
});

header won't work for all

Use below simple code

<?php
        echo "<script> location.href='new_url'; </script>";
        exit;
?>

"True" and "False" do not work, to disable, set to value disabled.

$('.someElement').attr('disabled', 'disabled');

To enable, remove.

$('.someElement').removeAttr('disabled');

Also, don't worry about multiple items being selected, jQuery will operate on all of them that match. If you need just one you can use many things :first, :last, nth, etc.

You are using name and not id as other mention -- remember, if you use id valid xhtml requires the ids be unique.

This is an old post, but I was looking for answer to this same question,

Why not try something like:

scale_color_manual(values = c("foo" = "#999999", "bar" = "#E69F00"))

If you have categorical values, I don't see a reason why this should not work.

You can also cross reference repos:

githubuser/repository#xxx

xxx being the issue number

<input name="submit" type="submit" id="submit" value="Save" />
<input name="process" type="submit" id="process" value="Process" />

And in your controller action:

public ActionResult SomeAction(string submit)
{
    if (!string.IsNullOrEmpty(submit))
    {
        // Save was pressed
    }
    else
    {
        // Process was pressed
    }
}

See if the below helps you:

I was using the following earlier:

ClientScript.RegisterClientScriptBlock(Page.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>");

After implementing AJAX in this page, it stopped working. After reading your blog, I changed the above to:

ScriptManager.RegisterClientScriptBlock(imgBtnSubmit, this.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>", false);

This is working perfectly fine.

(It’s .NET 2.0 Framework, I am using)

You can do that with the following:

Form3 formshow = new Form3();

formshow.ShowDialog();

//If url is something.domain.com this returns -> domain.com
function getDomain() {
  return window.location.hostname.replace(/([a-zA-Z0-9]+.)/,"");
}

You can also do this:

NSNumber *number = @([dictionary[@"id"] intValue]]);

Have fun!

I don't know, since when this is possible, but you can simply add <font> </font> to your string.xml which will automatically change the color per text. No need to add any additional code such as spannable text etc.

Example

<string name="my_formatted_text">
    <font color="#FF0707">THIS IS RED</font>
    <font color="#0B132B">AND NOW BLUE</font>
</string>

invalidate(); calls the list view to invalidate itself (ie. background color)
invalidateViews(); calls all of its children to be invalidated. allowing you to update the children views

I assume its some type of efficiency thing preventing all of the items to constantly have to be redraw if not necessary.

This is a supplement answer related to the OP:

An easy and reliable solution to add Javadocs comments in Eclipse:

1. Go to Help > Eclipse Marketplace....
2. Find "JAutodoc".
3. Install it and restart Eclipse.

To use this tool, right-click on class and click on JAutodoc.

Here is one way to do it from an article titled "Format query output into an HTML table - the easy way [archive]". You would need to substitute the details of your own query for the ones in this example, which gets a list of tables and a row count.

declare @body varchar(max)

set @body = cast( (
select td = dbtable + '</td><td>' + cast( entities as varchar(30) ) + '</td><td>' + cast( rows as varchar(30) )
from (
      select dbtable  = object_name( object_id ),
             entities = count( distinct name ),
             rows     = count( * )
      from sys.columns
      group by object_name( object_id )
      ) as d
for xml path( 'tr' ), type ) as varchar(max) )

set @body = '<table cellpadding="2" cellspacing="2" border="1">'
          + '<tr><th>Database Table</th><th>Entity Count</th><th>Total Rows</th></tr>'
          + replace( replace( @body, '&lt;', '<' ), '&gt;', '>' )
          + '</table>'

print @body

Once you have @body, you can then use whatever email mechanism you want.

Your worst case scenario isn't as bad as you think.

You are already parsing the RSS feed, so you already have the image URLs. Say you have an image URL like http://otherdomain.com/someimage.jpg. You rewrite this URL as https://mydomain.com/imageserver?url=http://otherdomain.com/someimage.jpg&hash=abcdeafad. This way, the browser always makes request over https, so you get rid of the problems.

The next part - create a proxy page or servlet that does the following -

1. Read the url parameter from the query string, and verify the hash
2. Download the image from the server, and proxy it back to the browser
3. Optionally, cache the image on disk

This solution has some advantages. You don't have to download the image at the time of creating the html. You don't have to store the images locally. Also, you are stateless; the url contains all the information necessary to serve the image.

Finally, the hash parameter is for security; you only want your servlet to serve images for urls you have constructed. So, when you create the url, compute md5(image_url + secret_key) and append it as the hash parameter. Before you serve the request, recompute the hash and compare it to what was passed to you. Since the secret_key is only known to you, nobody else can construct valid urls.

If you are developing in java, the Servlet is just a few lines of code. You should be able to port the code below on any other back-end technology.

/*
targetURL is the url you get from RSS feeds
request and response are wrt to the browser
Assumes you have commons-io in your classpath
*/

protected void proxyResponse (String targetURL, HttpServletRequest request,
 HttpServletResponse response) throws IOException {
    GetMethod get = new GetMethod(targetURL);
    get.setFollowRedirects(true);    
    /*
     * Proxy the request headers from the browser to the target server

When you want to create json format it had to be in this format for it to read:

[ 
  {
    "":"",
    "":[
     {
       "":"",
       "":""
     }
    ]
  }

try to insert your img inside your h4 DEMO

<h4 class='liketext'><img style='height: 24px; width: 24px; margin-right: 4px;' src='design/like.png'/>$likes</h4>
<h4 class='liketext'> <img style='height: 24px; width: 24px; margin-right: 4px;' src='design/dislike.png'/>$dislikes</h4>?

SQL Server 2012 and 2014 supports IIF(cont,true,false) function. Thus for minimal selection you can use it like

SELECT IIF(first>second, second, first) the_minimal FROM table

While IIF is just a shorthand for writing CASE...WHEN...ELSE, it's easier to write.

As a quick addition, and I'm surprised nobody has thought of this, you could use the in operator:

"chrome" in window

Obviously this isn't using JQuery, but I figured I'd put it since it's handy for times when you aren't using any external libraries.

public static string textDataSource = "Data Source=localhost;Initial Catalog=TEST_C;User ID=sa;Password=P@ssw0rd";

public static DataSet LoaderDataSet(string StrSql)      
{
    SqlConnection cnn;            
    SqlDataAdapter dad;
    DataSet dts = new DataSet();
    cnn = new SqlConnection(textDataSource);
    dad = new SqlDataAdapter(StrSql, cnn);
    try
    {
        cnn.Open();
        dad.Fill(dts);
        cnn.Close();

        return dts;
    }
    catch (Exception)
    {

        return dts;
    }
    finally
    {
        dad.Dispose();
        dts = null;
        cnn = null;
    }
}

Your Problem is because of getTime() . it always return following.

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

Because the max integer value is less then the return value by getTime() that why is showing wrong result.

Here is my solution..

        // Code that runs when an unhandled error occurs

        //direct user to error page 
        Server.Transfer("~/ErrorPages/Oops.aspx");

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

import yaml

data = dict(
    A = 'a',
    B = dict(
        C = 'c',
        D = 'd',
        E = 'e',
    )
)

with open('data.yml', 'w') as outfile:
    yaml.dump(data, outfile, default_flow_style=False)

The default_flow_style=False parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:

A: a
B: {C: c, D: d, E: e}

It would be great if you use :hover pseudo class over the onmouseover event

td:hover
{
   background-color:white
}

and for the default styling just use

td
{
  background-color:black
}

As you want to use these styling not over all the td elements then you need to specify the class to those elements and add styling to that class like this

.customTD
{
   background-color:black
}
.customTD:hover
{
  background-color:white;
}

You can also use :nth-child selector to select the td elements

The major difference between these tools is how they copy files.

scp basically reads the source file and writes it to the destination. It performs a plain linear copy, locally, or over a network.

rsync also copies files locally or over a network. But it employs a special delta transfer algorithm and a few optimizations to make the operation a lot faster. Consider the call.

rsync A host:B

• rsync will check files sizes and modification timestamps of both A and B, and skip any further processing if they match.

• If the destination file B already exists, the delta transfer algorithm will make sure only differences between A and B are sent over the wire.

• rsync will write data to a temporary file T, and then replace the destination file B with T to make the update look "atomic" to processes that might be using B.

Another difference between them concerns invocation. rsync has a plethora of command line options, allowing the user to fine tune its behavior. It supports complex filter rules, runs in batch mode, daemon mode, etc. scp has only a few switches.

In summary, use scp for your day to day tasks. Commands that you type once in a while on your interactive shell. It's simpler to use, and in those cases rsync optimizations won't help much.

For recurring tasks, like cron jobs, use rsync. As mentioned, on multiple invocations it will take advantage of data already transferred, performing very quickly and saving on resources. It is an excellent tool to keep two directories synchronized over a network.

Also, when dealing with large files, use rsync with the -P option. If the transfer is interrupted, you can resume it where it stopped by reissuing the command. See Sid Kshatriya's answer.

git-bash uses standard unix commands.

ls for directory listing cd for change directory

more here -> http://ss64.com/bash/ Not all of these will work, but the file based ones mostly do.

Copy the folder, firefox.exe is in and place in the c:\ only. The script is having a hard time climbing your file tree. I found that when I placed the *.exe file in the c:\ it eliminated the error message " file not found."

Why don't you try something like:

lastBusDay = datetime.datetime.today()
if datetime.date.weekday(lastBusDay) not in range(0,5):
    lastBusDay = 5

It could be due to below reasons: -

1. Either you dont have INTERNET permission in manifest file. If so then please use this statement <uses-permission android:name="android.permission.INTERNET" />

2. Or you are connected to a network but your internet connection is not working. Like you are connected to a Wi-Fi but it doesnt have internet connection or Mobile data on your phone is ON but you dont have data connectivity on your phone.

Point# 2 is interesting and its not assumption, I have tested the same at my end.

Hope this will help you

In cmd you can use the following:

c:\your directory\your folder\build>java -jar yourFile.jar 

However, you need to create you .jar file on your project if you use Netbeans. How just go to Run ->Clean and Build Project(your project name)

Also make sure you project properties Build->Packing has a yourFile.jar and check Build JAR after Compiling check Copy Depentent Libraries

Warning: Make sure your Environmental variables for Java are properly set.

Old way to compile and run a Java File from the command prompt (cmd)

Compiling: c:\>javac Myclass.java
Running: c:\>java com.myPackage.Myclass

I hope this info help.

For me it worked as I just copied a .nuget folder from a working solution to the existing one, and referenced it's content!

Try this:

    .rowhighlight > td { background: green;}

The below code doesn't return the correct screen size sometimes:

MediaQuery.of(context).size

I tested on SAMSUNG SM-T580, which returns {width: 685.7, height: 1097.1} instead of the real resolution 1920x1080.

Please use:

import 'dart:ui';

window.physicalSize;

You'll have to use svn directly:

svn checkout URL[@REV]... [PATH]

and

svn help co

gives you a little more help.

In some cases, i.e. when (if) you're just using float to have elements flow on the same "line", you might use

display: inline-block;

instead of

float: left;

Otherwise, using a clear element at the end works, even if it may go against the grain to need an element to do what should be CSS work.

The script element that loads the API is missing the required authentication parameter. If you are using the standard Maps JavaScript API, you must use a key parameter with a valid API key. If you are a Premium Plan customer, you must use either a client parameter with your client ID or a key parameter with a valid API key.

See the guide to API keys and client IDs.

The command you are seeking is comm. eg:-

comm -12 1.sorted.txt 2.sorted.txt

Here:

-1 : suppress column 1 (lines unique to 1.sorted.txt)

-2 : suppress column 2 (lines unique to 2.sorted.txt)

Add this to an htaccess file (and see edit notes added below):

   php_value memory_limit 300M
   php_value max_execution_time 259200
   php_value max_input_time 259200
   php_value session.gc_maxlifetime 1200

2021 EDIT:

As PHP and Apache evolve and grow, I think it is important for me to take a moment to mention a few things to consider and possible "gotchas" to consider:

• PHP can be run as a module or as CGI. It is not recommended to run as CGI as it creates a lot of opportunities for attack vectors [Read More]. Running as a module (the safer option) will trigger the settings to be used if the specific module from <IfModule is loaded.
• The answer indicates to write mod_php5.c in the first line. If you are using PHP 7, you would replace that with mod_php7.c.
• Sometimes after you make changes to your .htaccess file, restarting Apache or NGINX will not work. The most common reason for this is you are running PHP-FPM, which runs as a separate process. You need to restart that as well.
• Remember these are settings that are normally defined in your php.ini config file(s). This method is usually only useful in the event your hosting provider does not give you access to change those files. In circumstances where you can edit the PHP configuration, it is recommended that you apply these settings there.
• Finally, it's important to note that not all php.ini settings can be configured via an .htaccess file. A file list of php.ini directives can be found here, and the only ones you can change are the ones in the changeable column with the modes PHP_INI_ALL or PHP_INI_PERDIR.

I know this is a bit old, but in case another beginner is going through this, I'll share some code that covers a bit more of the basic operations, here is another example that also includes the option to cancel the process and also report to the user the status of the process. I'm going to add on top of the code given by Alex Aza in the solution above

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted;  //Tell the user how the process went
    backgroundWorker1.WorkerReportsProgress = true;
    backgroundWorker1.WorkerSupportsCancellation = true; //Allow for the process to be cancelled
}

//Start Process
private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

//Cancel Process
private void button2_Click(object sender, EventArgs e)
{
    //Check if background worker is doing anything and send a cancellation if it is
    if (backgroundWorker1.IsBusy)
    {
        backgroundWorker1.CancelAsync();
    }

}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);

        //Check if there is a request to cancel the process
        if (backgroundWorker1.CancellationPending)
        {
            e.Cancel = true;
            backgroundWorker1.ReportProgress(0);
            return;
        }
    }
    //If the process exits the loop, ensure that progress is set to 100%
    //Remember in the loop we set i < 100 so in theory the process will complete at 99%
    backgroundWorker1.ReportProgress(100);
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled)
    {
         lblStatus.Text = "Process was cancelled";
    }
    else if (e.Error != null)
    {
         lblStatus.Text = "There was an error running the process. The thread aborted";
    }
    else
    {
       lblStatus.Text = "Process was completed";
    }
}

Issue resolved.!!! Below are the solutions.

For Java 6: Add below jars into {JAVA_HOME}/jre/lib/ext. 1. bcprov-ext-jdk15on-154.jar 2. bcprov-jdk15on-154.jar

Add property into {JAVA_HOME}/jre/lib/security/java.security security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider

Java 7:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

Java 8:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

Issue is that it is failed to decrypt 256 bits of encryption.

Thank you everyone. Your ways are perfect. I would like to share another way I used to fix the problem. I used the function os.chdir(path) to change local directory to path. After which I saved image normally.

From the asar documentation

(the use of npx here is to avoid to install the asar tool globally with npm install -g asar)

Extract the whole archive:

npx asar extract app.asar destfolder 

Extract a particular file:

npx asar extract-file app.asar main.js

No, you would need to url-encode it, since base64 strings can contain the "+", "=" and "/" characters which could alter the meaning of your data - look like a sub-folder.

Valid base64 characters are below.

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=

if you just want to stopping insecure warning like:

/usr/lib/python3/dist-packages/urllib3/connectionpool.py:794: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html InsecureRequestWarning)

do:

requests.METHOD("https://www.google.com", verify=False)

verify=False

is the key, followings are not good at it:

requests.packages.urllib3.disable_warnings()

or

urllib3.disable_warnings()

but, you HAVE TO know, that might cause potential security risks.

exit(int code); is declared in stdlib.h so you need an

#include <stdlib.h>

Also:
- You have no parameter for the exit(), it requires an int so provide one.
- Burn this book, it uses goto which is (for everyone but linux kernel hackers) bad, very, very, VERY bad.

Edit:
Oh, and

void main()

is bad, too, it's:

int main(int argc, char *argv[])

In Ember.js you can use inline if helper in if block helper. It can replace || logical operator, for example:

{{#if (if firstCondition firstCondition secondCondition)}}
  (firstCondition || (or) secondCondition) === true
{{/if}}

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

Do an UPSERT:

UPDATE MyTable SET FieldA=@FieldA WHERE Key=@Key

IF @@ROWCOUNT = 0
   INSERT INTO MyTable (FieldA) VALUES (@FieldA)

http://en.wikipedia.org/wiki/Upsert

You can use below code for h2 and MySQl

    @Query(value = "SELECT req.CREATED_AT createdAt, req.CREATED_BY createdBy,req.APP_ID appId,req.NOTE_ID noteId,req.MODEL model FROM SUMBITED_REQUESTS  req inner join NOTE note where req.NOTE_ID=note.ID and note.CREATED_BY= :userId "
        ,
         countQuery = "SELECT count(*) FROM SUMBITED_REQUESTS req inner join NOTE note WHERE req.NOTE_ID=note.ID and note.CREATED_BY=:userId",
        nativeQuery = true)
Page<UserRequestsDataMapper> getAllRequestForCreator(@Param("userId") String userId,Pageable pageable);

You can use the HAVING clause.

SELECT * 
FROM tab_name
GROUP BY email_id
HAVING COUNT(*) = 1;

try this one

return Content("<form action='actionname' id='frmTest' method='post'><input type='hidden' name='someValue' value='" + someValue + "' /><input type='hidden' name='anotherValue' value='" + anotherValue + "' /></form><script>document.getElementById('frmTest').submit();</script>");

I had a different approach , used bootstrap panel to show it little more rich. Just to help someone and improve the answer.

This will give below look.

Note: We need to change the styles in order to use different header size.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

Sample Usage of the matter in question can be like:

class SampleObject(object):

    def __new__(cls, item):
        if cls.IsValid(item):
            return super(SampleObject, cls).__new__(cls)
        else:
            return None

    def __init__(self, item):
        self.InitData(item) #large amount of data and very complex calculations

...

ValidObjects = []
for i in data:
    item = SampleObject(i)
    if item:             # in case the i data is valid for the sample object
        ValidObjects.append(item)

I do not have enough reputation so I can not write a comment, it is crazy! I wish I could post it as a comment to weronika

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

The best way to answer your question is to see it in action.

<a id="test" onclick="alert('test')"> test </a> ?

In the js

var test = document.getElementById('test');
console.log( test.onclick ); 

As you see in the console, if you're using chrome it prints an anonymous function with the event object passed in, although it's a little different in IE.

function onclick(event) {
   alert('test')
}

I agree with some of your points about inline event handlers. Yes they are easy to write, but i don't agree with your point about having to change code in multiple places, if you structure your code well, you shouldn't need to do this.

I faced this problem where the following query doesn't work as expected:

select 1 where getdate()<>null

we expect it to show 1 because getdate() doesn't return null. I guess it has something to do with SQL failing to cast null as datetime and skipping the row! of course we know we should use IS or IS NOT keywords to compare a variable with null but when comparing two parameters it gets hard to handle the null situation. as a solution you can create your own compare function like the following:

CREATE FUNCTION [dbo].[fnCompareDates]
(
    @DateTime1 datetime,
    @DateTime2 datetime
)
RETURNS bit
AS
BEGIN
    if (@DateTime1 is null and @DateTime2 is null) return 1;
    if (@DateTime1 = @DateTime2) return 1;
    return 0
END

and re writing the query like:

select 1 where dbo.fnCompareDates(getdate(),null)=0

Using Abizern code for swift 2.2

let objectData = responseString!.dataUsingEncoding(NSUTF8StringEncoding)
let json = try NSJSONSerialization.JSONObjectWithData(objectData!, options: NSJSONReadingOptions.MutableContainers)

try to add display: block; (or replace the <span> by a <div>) (note that this could cause other problems becuase a <span> is inline by default - but you havn't posted the rest of your html)

A good example of using the Generic Repository pattern and implementing a generic solution for this might look something like this.

public IList<TEntity> Get<TParamater>(IList<Expression<Func<TEntity, TParamater>>> includeProperties)

{

    foreach (var include in includeProperties)
     {

        query = query.Include(include);
     }

        return query.ToList();
}

After struggling for some time, I think I found out quite simple solution.

Inspired by Robin Wilson I made this simple JS function (the original resizes both width and height, mine is just for the width):

 function changeFBPagePlugin() {
    var container_width = Number($('.fb-container').width()).toFixed(0);
    if (!isNaN(container_width)) {
        $(".fb-page").attr("data-width", container_width);
    }
    if (typeof FB !== 'undefined') {
        FB.XFBML.parse();
    }
};

It checks for the current width of the wrapping div and then puts the value inside fb-page div. The magic is done with FB.XFBML object, that is a part of Facebook SDK, which becomes available when you initialize the fb-page itself via window.fbAsyncInit

I bind my function to html body's onLoad and onResize:

<body onload="changeFBPagePlugin()" onresize="changeFBPagePlugin()">

On the page I have my fb-page plugin wrapped in another div that is used as reference:

<div class="fb-container"> 
    <div class="fb-page" ...stuff you need for FB page plugin... </div>
</div>

Finally the simple CSS for the wrapper to assure it stretches over the available space:

.fb-container {
    width: 95%;
    margin: 0px auto;
}

Putting all this together the results seem quite satisfying. Hopefuly this will help someone, although the question was posted quite a long time ago.

Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.

Do you have the key backed up somewhere?

Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.

Another easier way to do it is to upload your file to google sheets, then add a pivot, for the columns and rows select the same as you would with Excel, however, for values select Calculated Field and then in the formula type in =

They are hint to the compiler to emit instructions that will cause branch prediction to favour the "likely" side of a jump instruction. This can be a big win, if the prediction is correct it means that the jump instruction is basically free and will take zero cycles. On the other hand if the prediction is wrong, then it means the processor pipeline needs to be flushed and it can cost several cycles. So long as the prediction is correct most of the time, this will tend to be good for performance.

Like all such performance optimisations you should only do it after extensive profiling to ensure the code really is in a bottleneck, and probably given the micro nature, that it is being run in a tight loop. Generally the Linux developers are pretty experienced so I would imagine they would have done that. They don't really care too much about portability as they only target gcc, and they have a very close idea of the assembly they want it to generate.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

In general, you can the characters of a string from i until j with string[i:j]. string[:2] is shorthand for string[0:2]. This works for arrays as well.

Learn about python's slice notation at the official tutorial

You could use assign with a dict of column names and values.

In [1069]: df.assign(**{'col_new_1': np.nan, 'col2_new_2': 'dogs', 'col3_new_3': 3})
Out[1069]:
   col_1  col_2 col2_new_2  col3_new_3  col_new_1
0      0      4       dogs           3        NaN
1      1      5       dogs           3        NaN
2      2      6       dogs           3        NaN
3      3      7       dogs           3        NaN

You can get attribute value by following way

$model = Mage::getResourceModel('catalog/product');
$attribute_value = $model->getAttributeRawValue($productId, 'attribute_code', $storeId);

In C#, you can write

(long)(date - new DateTime(1970, 1, 1)).TotalMilliseconds

There's a well documented answer to your question at this url:

http://blogs.technet.com/b/heyscriptingguy/archive/2005/02/18/how-can-i-list-the-files-in-a-folder-and-all-its-subfolders.aspx

The answer shown at that URL is kind of complicated and uses WMI (Windows Management Instrumentation) to iterate through files and folders. But if you do a lot of Windows administration, it's worth the effort to learn WMI.

I'm posting this now in case you need something right now; but I think I used to use a filesystemobject based approach, and I'll look for some example, and I'll post it later if I find it.

I hope this is helpful.

import io, pygame, zipfile
archive = zipfile.ZipFile('images.zip', 'r')

# read bytes from archive
img_data = archive.read('img_01.png')

# create a pygame-compatible file-like object from the bytes
bytes_io = io.BytesIO(img_data)

img = pygame.image.load(bytes_io)

I was trying to figure this out for myself just now and thought this might be useful for anyone who comes across this question in the future.

Swift 4

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
        // delete item at indexPath
    tableView.deleteRows(at: [indexPath], with: .fade)

    }
    return [delete]
}

I believe the following work in version 0.11 and above. To check the version:

$ ipython --version

It may be worth adding this information to your question.

Solution:

You need to find the file ipython_notebook_config.py. Depending on your installation process this should be in somewhere like

.config/ipython/profile_default/ipython_notebook_config.py

where .config is in your home directory.

Once you have located this file find the following lines

# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}

Uncomment this line c.InlineBack... and define your default figsize in the second dictionary entry.

Note that this could be done in a python script (and hence interactively in IPython) using

pylab.rcParams['figure.figsize'] = (10.0, 8.0)

In the examples below the client is the browser and the server is the webserver hosting the website.

Before you can understand these technologies, you have to understand classic HTTP web traffic first.

Regular HTTP:

1. A client requests a webpage from a server.
2. The server calculates the response
3. The server sends the response to the client.

Ajax Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server at regular intervals (e.g. 0.5 seconds).
3. The server calculates each response and sends it back, just like normal HTTP traffic.

Ajax Long-Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server.
3. The server does not immediately respond with the requested information but waits until there's new information available.
4. When there's new information available, the server responds with the new information.
5. The client receives the new information and immediately sends another request to the server, re-starting the process.

HTML5 Server Sent Events (SSE) / EventSource:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection to the server.

3. The server sends an event to the client when there's new information available.

   • Real-time traffic from server to client, mostly that's what you'll need
   • You'll want to use a server that has an event loop
   • Connections with servers from other domains are only possible with correct CORS settings
   • If you want to read more, I found these very useful: (article), (article), (article), (tutorial).

HTML5 Websockets:

1. A client requests a webpage from a server using regular http (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection with the server.

3. The server and the client can now send each other messages when new data (on either side) is available.

   • Real-time traffic from the server to the client and from the client to the server
   • You'll want to use a server that has an event loop
   • With WebSockets it is possible to connect with a server from another domain.
   • It is also possible to use a third party hosted websocket server, for example Pusher or others. This way you'll only have to implement the client side, which is very easy!
   • If you want to read more, I found these very useful: (article), (article) (tutorial).

Comet:

Comet is a collection of techniques prior to HTML5 which use streaming and long-polling to achieve real time applications. Read more on wikipedia or this article.

Now, which one of them should I use for a realtime app (that I need to code). I have been hearing a lot about websockets (with socket.io [a node.js library]) but why not PHP ?

You can use PHP with WebSockets, check out Ratchet.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

To use image in Flutter. Do these steps.

1. Create a Directory inside assets folder named images. As shown in figure below

2. Put your desired images to images folder.

3. Open pubpsec.yaml file . And add declare your images.Like:--

4. Use this images in your code as.

  Card(
            elevation: 10,
              child: Container(
              decoration: BoxDecoration(
                color: Colors.orangeAccent,
              image: DecorationImage(
              image: AssetImage("assets/images/dropbox.png"),
          fit: BoxFit.fitWidth,
          alignment: Alignment.topCenter,
          ),
          ),
          child: Text("$index",style: TextStyle(color: Colors.red,fontSize: 16,fontFamily:'LangerReguler')),
                alignment: Alignment.center,
          ),
          );

@bninopaul 's answer is not completely for beginners

here is the code you can "copy and run"

import seaborn as sn
import pandas as pd
import matplotlib.pyplot as plt

array = [[13,1,1,0,2,0],
         [3,9,6,0,1,0],
         [0,0,16,2,0,0],
         [0,0,0,13,0,0],
         [0,0,0,0,15,0],
         [0,0,1,0,0,15]]

df_cm = pd.DataFrame(array, range(6), range(6))
# plt.figure(figsize=(10,7))
sn.set(font_scale=1.4) # for label size
sn.heatmap(df_cm, annot=True, annot_kws={"size": 16}) # font size

plt.show()

    wp_register_script('custom-js',WP_PLUGIN_URL.'/PLUGIN_NAME/js/custom.js',array(),NULL,true);
    wp_enqueue_script('custom-js');

    $wnm_custom = array( 'template_url' => get_bloginfo('template_url') );
    wp_localize_script( 'custom-js', 'wnm_custom', $wnm_custom );

and in custom.js

alert(wnm_custom.template_url);

First off, this is one of those things that slaps me in the face with surprise: renaming of a column requires creating an entirely new table and copying the data from the old table to the new table...

The GUI I've landed on to do SQLite operations is Base. It's got a nifty Log window that shows all the commands that have been executed. Doing a rename of a column via Base populates the log window with the necessary commands:

These can then be easily copied and pasted where you might need them. For me, that's into an ActiveAndroid migration file. A nice touch, as well, is that the copied data only includes the SQLite commands, not the timestamps, etc.

Hopefully, that saves some people time.

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

I really don't see what your problem is, the question is rather unspecific. Given Notepad++ I assume you use Windows.

You have so many options here, from the MinGW (using the GCC tool chain and GNU make) to using a modern MSVC. You can use the WDK (ddkbuild.bat/.cmd or plain build.exe), the Windows SDK (nmake.exe), other tools such as premake and CMake, or msbuild that comes with MSVC and the Windows SDK.

I mean the compiler names will differ, cl.exe for MSVC and the WDK and Windows SDK, gcc.exe for MinGW, but even from the console it is customary to organize your project in some way. This is what make and friends were invented for after all.

So to know the command line switches of your particular compiler consult the manual of that very compiler. To find ways to automate your build (i.e. the ability to run a simple command instead of a complex command line), you could sift through the list on Wikipedia or pick one of the tools I mentioned above and go with that.

Side-note: it isn't necessary to ask people not to mention IDEs. Most professional developers have automated their builds to run from a command line and not from within the IDE (as during the development cycle for example), because there are so many advantages to that approach.

This jQuery solution works for me in Chrome and Firefox, for both Ctrl+S and Cmd+S.

$(document).keydown(function(e) {

    var key = undefined;
    var possible = [ e.key, e.keyIdentifier, e.keyCode, e.which ];

    while (key === undefined && possible.length > 0)
    {
        key = possible.pop();
    }

    if (key && (key == '115' || key == '83' ) && (e.ctrlKey || e.metaKey) && !(e.altKey))
    {
        e.preventDefault();
        alert("Ctrl-s pressed");
        return false;
    }
    return true;
}); 

I think you should indeed be using the Control overload of the RegisterStartupScript.

I've tried the following code in a server control:

[ToolboxData("<{0}:AlertControl runat=server></{0}:AlertControl>")]
public class AlertControl : Control{
    protected override void OnInit(EventArgs e){
        base.OnInit(e);
        string script = "alert(\"Hello!\");";
        ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", script, true);
    }
}

Then in my page I have:

protected override void OnInit(EventArgs e){
    base.OnInit(e);
    Placeholder1.Controls.Add(new AlertControl());
}

Where Placeholder1 is a placeholder in an update panel. The placeholder has a couple of other controls on in it, including buttons.

This behaved exactly as you would expect, I got an alert saying "Hello" every time I loaded the page or caused the update panel to update.

The other thing you could look at is to hook into some of the page lifecycle events that are fired during an update panel request:

Sys.WebForms.PageRequestManager.getInstance()
   .add_endRequest(EndRequestHandler);

The PageRequestManager endRequestHandler event fires every time an update panel completes its update - this would allow you to call a method to set up your control.

My only other questions are:

• What is your script actually doing?
• Presumably you can see the script in the HTML at the bottom of the page (just before the closing </form> tag)?
• Have you tried putting a few "alert("Here");" calls in your startup script to see if it's being called correctly?
• Have you tried Firefox and Firebug - is that reporting any script errors?

SVN seems to handle binary deltas more efficiently than Git.

I had to decide on a versioning system for documentation (JPEG files, PDF files, and .odt files). I just tested adding a JPEG file and rotating it 90 degrees four times (to check effectiveness of binary deltas). Git's repository grew 400%. SVN's repository grew by only 11%.

So it looks like SVN is much more efficient with binary files.

So my choice is Git for source code and SVN for binary files like documentation.

In the designer, set the form's Visible property to false. Then avoid calling Show() until you need it.

A better paradigm is to not create an instance of the form until you need it.

Yes, you can use it. Here is how:

1. Your Project -> right click -> Import -> File System -> yourjar.jar
2. Your Project -> right click -> Properties -> Java Build Path -> Libraries -> Add Jar -> yourjar.jar

I did this by installing Cygwin64 from this link https://www.cygwin.com/ Then - View Full, Search gcc and scroll down to find pkg-config. Click on icon to select latest version. This worked for me well.

It's a few less clicks in VS2017, and if the local repo is ahead of the Git clone, click Source control from the pop-up project menu:


This brings up the Team Explorer Changes dialog:


Type in a description- here it's "Stack Overflow Example Commit".
Make a choice of the three options on offer, all of which are explained here.

Try something like this:

df.select([c for c in df.columns if c in ['_2','_4','_5']]).show()

This feature is known as generics. http://msdn.microsoft.com/en-us/library/512aeb7t(v=vs.100).aspx

An example of this is to make a collection of items of a specific type.

class MyArray<T>
{
    T[] array = new T[10];

    public T GetItem(int index)
    {
        return array[index];
    }
}

In your code, you could then do something like this:

MyArray<int> = new MyArray<int>();

In this case, T[] array would work like int[] array, and public T GetItem would work like public int GetItem.

If you're trying to print a specific register in GDB, you have to omit the % sign. For example,

info registers eip

If your executable is 64 bit, the registers start with r. Starting them with e is not valid.

info registers rip

Those can be abbreviated to:

i r rip

To answer people thinking you "have to" use vector instead of unique_ptr I have a case in CUDA programming on GPU when you allocate memory in Device you must go for a pointer array (with cudaMalloc). Then, when retrieving this data in Host, you must go again for a pointer and unique_ptr is fine to handle pointer easily. The extra cost of converting double* to vector<double> is unnecessary and leads to a loss of perf.

What happens when you set all of the attributes in one attr() command like so

$(this).attr({
               id : this.id + '_' + new_id,
               name: this.name + '_' + new_id,
               value: 'test' 
             });

DOMDocument is slow to type and phpQuery has bad memory leak issues. I ended up using:

https://github.com/wasinger/htmlpagedom

To select a class:

include 'includes/simple_html_dom.php';

$doc = str_get_html($html);
$href = $doc->find('.lastPage')[0]->href;

I hope this helps someone else as well

I know this is old, but I have to add this in here..

The address bar will not disappear if you're NOT using https.

ALSO

If you are using https and the address bar still won't hide, you might have some https errors in your webpage (such as certain images being served from a non-https location.)

That would be the %CD% variable.

@echo off
echo %CD%

%CD% returns the current directory the batch script is in.

to add scroll u need to define max-height of your div and then add overflow-y

so do something like this

.my_scroll_div{
    overflow-y: auto;
    max-height: 100px;
}

adb uninstall <package_name>

can be used to uninstall an app via your PC. If you want this to happen automatically every time you launch your app via Android Studio, you can do this:

1. In Android Studio, click the drop down list to the left of Run button, and select Edit configurations...
2. Click on app under Android Application, and in General Tab, find the heading 'Before Launch'
3. Click the + button, select Run external tool, click the + button in the popup window.
4. Give some name (Eg adb uninstall) and description, and type adb in Program: and uninstall <your-package-name> in Parameters:. Make sure that the new item is selected when you click Ok in the popup window.

Note: If you do not have adb in your PATH environment variable, give the full path to adb in Program: field (eg /home/user/android/sdk/platform-tools/adb).

I agree with Brandrew, the problem is most likely caused by some missing dlls that can't be found neither on the system path nor in the folder where the executable is. Try putting the following DLLs nearby the executable:

• the Visual Studio C++ runtime (in VS2008, they could be found at places like C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86.) Include all 3 of the DLL files as well as the manifest file.
• the four OpenCV dlls (cv210.dll, cvaux210.dll, cxcore210.dll and highgui210.dll, or the ones your OpenCV version has)
• if that still doesn't work, try the debug VS runtime (executables compiled for "Debug" use a different set of dlls, named something like msvcrt9d.dll, important part is the "d")

Alternatively, try loading the executable into Dependency Walker ( http://www.dependencywalker.com/ ), it should point out the missing dlls for you.

Correct, file handle 1 for the process is STDOUT, redirected by the 1> or by > (1 can be omitted, by convention, the command interpreter [cmd.exe] knows to handle that). File handle 2 is STDERR, redirected by 2>.

Note that if you're using these to make log files, then unless you're sending the outut to _uniquely_named_ (eg date-and-time-stamped) log files, then if you run the same process twice, the redirected will overwrite (replace) the previous log file.

The >> (for either STDOUT or STDERR) will APPEND not REPLACE the file. So you get a cumulative logfile, showwing the results from all runs of the process - typically more useful.

Happy trails...

Double stars (**) are exponentiation. So "2 times 2" and "2 to the power 2" are the same. Change the numbers and you'll see a difference.

The other big difference is Abandon does not remove items immediately, but when it does then cleanup it does a loop over session items to check for STA COM objects it needs to handle specially. And this can be a problem.

Under high load it's possible for two (or more) requests to make it to the server for the same session (that is two requests with the same session cookie). Their execution will be serialized, but since Abandon doesn't clear out the items synchronously but rather sets a flag it's possible for both requests to run, and both requests to schedule a work item to clear out session "later". Both these work items can then run at the same time, and both are checking the session objects, and both are clearing out the array of objects, and what happens when you have two things iterating over a list and changing it?? Boom! And since this happens in a queueuserworkitem callback and is NOT done in a try/catch (thanks MS), it will bring down your entire app domain. Been there.

Variables have a type and a value.

• $var = "test" is a string that contain "test"
• $var2 = 24 is an integer vhose value is 24.

When you use these variables (in PHP), sometimes you don't have the good type. For example, if you do

if ($var == 1) {... do something ...}

PHP have to convert ("to cast") $var to integer. In this case, "$var == 1" is true because any non-empty string is casted to 1.

When using ===, you check that the value AND THE TYPE are equal, so "$var === 1" is false.

This is useful, for example, when you have a function that can return false (on error) and 0 (result) :

if(myFunction() == false) { ... error on myFunction ... }

This code is wrong as if myFunction() returns 0, it is casted to false and you seem to have an error. The correct code is :

if(myFunction() === false) { ... error on myFunction ... }

because the test is that the return value "is a boolean and is false" and not "can be casted to false".

1. For MySQL:

SELECT FIND_IN_SET(5, columnname) AS result 
FROM table

2.For Postgres SQL :

SELECT * 
FROM TABLENAME f
WHERE 'searchvalue' = ANY (string_to_array(COLUMNNAME, ','))

Example

select * 
from customer f
where '11' = ANY (string_to_array(customerids, ','))

Use BufferedReader and InputStreamReader classes.

BufferedReader buffer=new BufferedReader(new InputStreamReader(System.in));
String line=buffer.readLine();

Or use java.util.Scanner class methods.

Scanner scan=new Scanner(System.in);

Well the problem with the GET is that the user is able to change the value by himself if he has some knowledges. I wrote this so that PHP is able to retrive the timezone from Javascript:

// -- index.php

<?php
  if (!isset($_COOKIE['timezone'])) {
?>
<html>
<script language="javascript">  
  var d = new Date(); 
  var timezoneOffset = d.getTimezoneOffset() / 60;
  // the cookie expired in 3 hours
  d.setTime(d.getTime()+(3*60*60*1000));
  var expires = "; expires="+d.toGMTString();
  document.cookie = "timezone=" +  timezoneOffset + expires + "; path=/";
  document.location.href="index.php"
</script>
</html>
<?php
} else {
  ?>

  <html>
  <head>
  <body>

  <?php 
  if(isset($_COOKIE['timezone'])){ 
    dump_var($_COOKIE['timezone']); 
  } 
}
?>

I used KUE with socketIO like you described. I stored the socketID with the job and could then retreive it in the Job Complete.. KUE is based on redis and has good examples on github

something like this....

jobs.process('YourQueuedJob',10, function(job, done){
    doTheJob(job, done);
});


function doTheJob(job, done){
    var socket = io.sockets.sockets[job.data.socketId];
    try {
        socket.emit('news', { status : 'completed' , task : job.data.task });
    } catch(err){
        io.sockets.emit('news', { status : 'fail' , task : job.data.task , socketId: job.data.socketId});
    }
    job.complete();
}

Have you tried

SELECT DATEADD(mi, -15,'2000-01-01 08:30:00')

DATEDIFF is the difference between 2 dates.

I usually get "Attempted to read or write protected memory" when calling the "Show" method on some WinForms. I checked and there doesn't appear anything special about those forms. I don't know why this works (maybe someone can tell me) but usually moving the code that gets executed in the "Load" event of the form to the "Shown" event fixes it for me and I never see it again.

if (cursor.getCount() == 0)
  return;

cursor.moveToFirst();

while (!cursor.isAfterLast())
{

}

cursor.close();

If you are like me, and starring at your angular/ionic typescript, which looks like..

  getPdf(endpoint: string): Observable<Blob> {
    let url = this.url + '/' + endpoint;
    let token = this.msal.accessToken;
    console.log(token);
    return this.http.post<Blob>(url, {
      headers: new HttpHeaders(
        {
          'Access-Control-Allow-Origin': 'https://localhost:5100',
          'Access-Control-Allow-Methods': 'POST',
          'Content-Type': 'application/pdf',
          'Authorization': 'Bearer ' + token,
          'Accept': '*/*',
        }),
        //responseType: ResponseContentType.Blob,
      });
  }

And while you are setting options but can't seem to figure why they aren't anywhere..

Well.. if you were like me and started this post from a copy/paste of a get, then...

Change to:

  getPdf(endpoint: string): Observable<Blob> {
    let url = this.url + '/' + endpoint;
    let token = this.msal.accessToken;
    console.log(token);
    return this.http.post<Blob>(url, null, { //  <-----  notice the null  *****
      headers: new HttpHeaders(
        {
          'Authorization': 'Bearer ' + token,
          'Accept': '*/*',
        }),
        //responseType: ResponseContentType.Blob,
      });
  }

I found the below stuff in ffmpeg Docs. Hope this helps! :)

Reference: http://ffmpeg.org/ffmpeg.html#toc-Generic-options

‘-report’ Dump full command line and console output to a file named program-YYYYMMDD-HHMMSS.log in the current directory. This file can be useful for bug reports. It also implies -loglevel verbose.

Note: setting the environment variable FFREPORT to any value has the same effect.

The Google Python Style Guide has the following convention:

module_name, package_name, ClassName, method_name, ExceptionName, function_name, GLOBAL_CONSTANT_NAME, global_var_name, instance_var_name, function_parameter_name, local_var_name.

A similar naming scheme should be applied to a CLASS_CONSTANT_NAME

For any special characters you should use '\'. So, for matching parentheses - /\(/

A bit late to the party, but here is an implementation that works with multiple tables on the same page and "jank" free (using requestAnimationFrame). Also there's no need to provide any width on the columns. Horizontal scrolling works as well.

The headers are defined in a div so you are free to add any markup there (like buttons), if required. This is all the HTML that is needed:

<div class="tbl-resp">
  <table id="tbl1" class="tbl-resp__tbl">
     <thead>
      <tr>
        <th>col 1</th>
        <th>col 2</th>
        <th>col 3</th>
      </tr>
    </thead> 
  </table>
</div>

I found a workaround.

1. Export with a white background (or other color that will work with transparent graphics). This will be out "whitescreen" layer.
2. Export with "bluescreen" background, or some terrible other color that will make it easy to select out the background from foreground.
3. Open the bluescreen version as a layer on top of the white screen.
4. Use the bluescreen layer to select out only the parts you want to use.
5. Create a mask for the whitescreen layer with the selection made from the bluescreen layer.

This will get good results for edges and aliasing, whilst retaining a good color for the see-

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

I got the same error while I forgot to use shell=True in the subprocess.call.

subprocess.call('python modify_depth_images.py', shell=True)

Running External Command

To run an external command without interacting with it, such as one would do with os.system(), Use the call() function.

import subprocess

Simple command subprocess.call(['ls', '-1'], shell=True)

int i;
int j;

int * const ptr1 = &i;

The compiler will stop you changing ptr1.

const int * ptr2 = &i;

The compiler will stop you changing *ptr2.

ptr1 = &j; // error
*ptr1 = 7; // ok

ptr2 = &j; // ok
*ptr2 = 7; // error

Note that you can still change *ptr2, just not by literally typing *ptr2:

i = 4;
printf("before: %d\n", *ptr2); // prints 4
i = 5;
printf("after: %d\n", *ptr2); // prints 5
*ptr2 = 6; // still an error

You can also have a pointer with both features:

const int * const ptr3 = &i;

I tried using the local IP address to connect as well as a public one. I've tried:

Yes, the site can communicate with the server Named pipes/TCP is enabled. Remote connections are allowed. Windows Firewall is off Created an exception for port 1433 in Windows Firewall. Enabled everything in SQL Server Configuration Manager.

i ensured and did the above as well and I just want to share that the DOUBLE BACKSLASH

oBuilder.DataSource = "SPECIFICPCNAME\SQLEXPRESS";

Using a SINGLE BACKSLASH resulted into a build error i.e.: Error 1 Unrecognized escape sequence

I hope this helps the next guy - I've sacrificed dinner, midnight snack and NBA highlights time solving this (shame)

Thanks to [Tamizh venthan] ^_^

-XX:PermSize -XX:MaxPermSize are used to set size for Permanent Generation.

Permanent Generation: The Permanent Generation is where class files are kept. These are the result of compiled classes and JSP pages. If this space is full, it triggers a Full Garbage Collection. If the Full Garbage Collection cannot clean out old unreferenced classes and there is no room left to expand the Permanent Space, an Out-of- Memory error (OOME) is thrown and the JVM will crash.

I had this error and fixed it by removing a thrown exception from beside the method to a try/catch block

For example: FROM:

public static HashMap<String, String> getMap() throws SQLException
{

}

TO:

public static Hashmap<String,String> getMap()
{
  try{

  }catch(SQLException)
  { 
  }
}

If you need to use integers of certain length, you probably should use some platform independent headers to help you. Boost is a good place to look at.

I found that the safest and reliable way to do it is to use FileReader().

Demo: Image to Base64

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
  </head>
  <body>
    <input id="myinput" type="file" onchange="encode();" />
    <div id="dummy">
    </div>
    <div>
      <textarea style="width:100%;height:500px;" id="txt">
      </textarea>
    </div>
    <script>
      function encode() {
        var selectedfile = document.getElementById("myinput").files;
        if (selectedfile.length > 0) {
          var imageFile = selectedfile[0];
          var fileReader = new FileReader();
          fileReader.onload = function(fileLoadedEvent) {
            var srcData = fileLoadedEvent.target.result;
            var newImage = document.createElement('img');
            newImage.src = srcData;
            document.getElementById("dummy").innerHTML = newImage.outerHTML;
            document.getElementById("txt").value = document.getElementById("dummy").innerHTML;
          }
          fileReader.readAsDataURL(imageFile);
        }
      }
    </script>
  </body>

If you only want to remove the last commit from the remote repository without messing up with your local repository, here's a one-liner:

git push origin +origin/master~:master

This uses the following syntax:

git push <remote> <refspec>

Here, <remote> is origin, and <refspec> has the following structure:

+origin/master~:master

Details can be found in git-push(1). The preceding + means "force push this ref", and the other part means "from origin/master~ to master (of remote origin)". It isn't hard to know that origin/master~ is the last commit before origin/master, right?

I found when doing this that in order to set the gravity to center, and still have your password hint show when using inputType, the android:gravity="Center" must be at the end of your XML line.

<EditText android:textColor="#000000" android:id="@+id/editText2" 
    android:layout_width="fill_parent" android:hint="Password" 
    android:background="@drawable/rounded_corner" 
    android:layout_height="fill_parent" 
    android:nextFocusDown="@+id/imageButton1" 
    android:nextFocusRight="@+id/imageButton1" 
    android:nextFocusLeft="@+id/editText1"
    android:nextFocusUp="@+id/editText1" 
    android:inputType="textVisiblePassword" 
    android:textColorHint="#999999" 
    android:textSize="16dp" 
    android:gravity="center">
</EditText>

Add this this to dependencies to force using latest version of findbugs library:

compile 'com.google.code.findbugs:jsr305:2.0.1'

No need to install any other package.

Run this command

node server.js > stdout.txt 2> stderr.txt &

server.js is your server file or it can be api.js

After that hit "exit" to close terminal

exit

this is my test function that I use to check Memcache on the server

<?php     
public function test()
 {
    // memcache test - make sure you have memcache extension installed and the deamon is up and running
    $memcache = new Memcache;
    $memcache->connect('localhost', 11211) or die ("Could not connect");

    $version = $memcache->getVersion();
    echo "Server's version: ".$version."<br/>\n";

    $tmp_object = new stdClass;
    $tmp_object->str_attr = 'test';
    $tmp_object->int_attr = 123;

    $memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
    echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

    $get_result = $memcache->get('key');
    echo "Data from the cache:<br/>\n";

    var_dump($get_result);
 }

if you see something like this

    Server's version: 1.4.5_4_gaa7839e
    Store data in the cache (data will expire in 10 seconds)
    Data from the cache:
    object(stdClass)#3 (2) { ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }

it means that everything is okay

Cheers!

My solution is based on XML configuration using spring-boot-starter-log4j. The example is a basic example using spring-boot-starter and the two Loggers writes into different log files.

An established connection was aborted by the software in your host machine

That is a boiler-plate error message, it comes out of Windows. The underlying error code is WSAECONNABORTED. Which really doesn't mean more than "connection was aborted". You have to be a bit careful about the "your host machine" part of the phrase. In the vast majority of Windows application programs, it is indeed the host that the desktop app is connected to that aborted the connection. Usually a server somewhere else.

The roles are reversed however when you implement your own server. Now you need to read the error message as "aborted by the application at the other end of the wire". Which is of course not uncommon when you implement a server, client programs that use your server are not unlikely to abort a connection for whatever reason. It can mean that a fire-wall or a proxy terminated the connection but that's not very likely since they typically would not allow the connection to be established in the first place.

You don't really know why a connection was aborted unless you have insight what is going on at the other end of the wire. That's of course hard to come by. If your server is reachable through the Internet then don't discount the possibility that you are being probed by a port scanner. Or your customers, looking for a game cheat.

a simple way:

in view(pass the id value):

<td><?php echo anchor('textarea/delete_row?id='.$row->id, 'DELETE', 'id="$row->id"'); ?></td>

in controller(receive the id):

$id = $this->input->get('id');
$this->load->model('mod1');
$this->mod1->row_delete($id);

in model(get the passed args):

function row_delete($id){}

Actually, you should use the ajax to POST the id value to controller and delete the row, not the GET.

You are right that this has long since been implemented in .NET Core.

At the time of writing (September 2019), the project.json file of NuGet 3.x+ has been superseded by PackageReference (as explained at https://docs.microsoft.com/en-us/nuget/archive/project-json).

To get access to the *Async methods of the HttpClient class, your .csproj file must be correctly configured.

Open your .csproj file in a plain text editor, and make sure the first line is
<Project Sdk="Microsoft.NET.Sdk.Web">
(as pointed out at https://docs.microsoft.com/en-us/dotnet/core/tools/project-json-to-csproj#the-csproj-format).

To get access to the *Async methods of the HttpClient class, you also need to have the correct package reference in your .csproj file, like so:

<ItemGroup>
    <!-- ... -->
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <!-- ... -->
</ItemGroup>

(See https://docs.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files#adding-a-packagereference. Also: We recommend applications targeting ASP.NET Core 2.1 and later use the Microsoft.AspNetCore.App metapackage, https://docs.microsoft.com/en-us/aspnet/core/fundamentals/metapackage)

Methods such as PostAsJsonAsync, ReadAsAsync, PutAsJsonAsync and DeleteAsync should now work out of the box. (No using directive needed.)

Update: The PackageReference tag is no longer needed in .NET Core 3.0.

INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).

You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).

To Store "Country + area + number separately". You can try using a VARCHAR(20), this allows you the ability to store international phone numbers properly, should that need arise.

You could try one of two things or a combination of both.

1. Be sure that your controller's name starts with a capital letter. eg "Mycontroller.php"
2. If you have not made any changes to your route, for some strange reason, you might have to include capital letters in your url. e.g if your controller is 'Mycontroller.php' with a function named 'testfunc' inside it, then your url will look like this: "http://www.yourdomain/index.php/Mycontroller/testfunc". Note the capital letter. (I'm assuming you haven't added the htaccess file to remove the 'index.php' part. If you have, just remove it from the url.)

I hope this helps someone

You can use regular expressions:

if (d.matches(".*Hey.*")) {
    c.setText("OUTPUT: SUCCESS!");
} else {
    c.setText("OUTPUT: FAIL!");  
}

.* -> 0 or more of any characters

Hey -> The string you want

If you will be checking this often, it is better to compile the regular expression in a Pattern object and reuse the Pattern instance to do the checking.

private static final Pattern HEYPATTERN = Pattern.compile(".*Hey.*");
[...]
if (HEYPATTERN.matcher(d).matches()) {
    c.setText("OUTPUT: SUCCESS!");
} else {
    c.setText("OUTPUT: FAIL!");  
}

Just note this will also match "Heyburg" for example since you didn't specify you're searching for "Hey" as an independent word. If you only want to match Hey as a word, you need to change the regex to .*\\bHey\\b.*

Change to MyISAM engine and run this command

REPAIR TABLE tbl_name USE_FRM;

You can just use the Select() extension method:

IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };
IEnumerable<string> strings = integers.Select(i => i.ToString());

Or in LINQ syntax:

IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };

var strings = from i in integers
              select i.ToString();

It sounds like you are trying to do something like this:

• Static HTML views
• Spring controllers serving AJAX

If that is the case, as previously mentioned, the most efficient way is to let the web server(not Spring) handle HTML requests as static resources. So you'll want the following:

1. Forward all .html, .css, .js, .png, etc requests to the webserver's resource handler
2. Map all other requests to spring controllers

Here is one way to accomplish that...

web.xml - Map servlet to root (/)

<servlet>
            <servlet-name>sprung</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            ...
<servlet>

<servlet-mapping>
            <servlet-name>sprung</servlet-name>
            <url-pattern>/</url-pattern>
</servlet-mapping>

Spring JavaConfig

public class SpringSprungConfig extends DelegatingWebMvcConfiguration {

    // Delegate resource requests to default servlet
    @Bean
    protected DefaultServletHttpRequestHandler defaultServletHttpRequestHandler() {
        DefaultServletHttpRequestHandler dsrh = new DefaultServletHttpRequestHandler();
        return dsrh;
    }

    //map static resources by extension
    @Bean
    public SimpleUrlHandlerMapping resourceServletMapping() {
        SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();

        //make sure static resources are mapped first since we are using
        //a slightly different approach
        mapping.setOrder(0);
        Properties urlProperties = new Properties();
        urlProperties.put("/**/*.css", "defaultServletHttpRequestHandler");
        urlProperties.put("/**/*.js", "defaultServletHttpRequestHandler");
        urlProperties.put("/**/*.png", "defaultServletHttpRequestHandler");
        urlProperties.put("/**/*.html", "defaultServletHttpRequestHandler");
        urlProperties.put("/**/*.woff", "defaultServletHttpRequestHandler");
        urlProperties.put("/**/*.ico", "defaultServletHttpRequestHandler");
        mapping.setMappings(urlProperties);
        return mapping;
    }

    @Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = super.requestMappingHandlerMapping();

        //controller mappings must be evaluated after the static resource requests
        handlerMapping.setOrder(1);
        handlerMapping.setInterceptors(this.getInterceptors());
        handlerMapping.setPathMatcher(this.getPathMatchConfigurer().getPathMatcher());
        handlerMapping.setRemoveSemicolonContent(false);
        handlerMapping.setUseSuffixPatternMatch(false);
        //set other options here
        return handlerMapping;
    }
}

Additional Considerations

• Hide .html extension - This is outside the scope of Spring if you are delegating the static resource requests. Look into a URL rewriting filter.
• Templating - You don't want to duplicate markup in every single HTML page for common elements. This likely can't be done on the server if serving HTML as a static resource. Look into a client-side *VC framework. I'm fan of YUI which has numerous templating mechanisms including Handlebars.

I'd give all the responses here a try first. But I wanted to just throw in what I do, just in case these do not work for you.

I've tried to solve the same problem you're having before, and in the end, what I decided on doing is to have only one JRE installed on my system at a given time. I do have about 10 different JDKs (1.3 through 1.6, and from various vendors - Sun, Oracle, IBM), since I do need it for development, but only one standalone JRE.

This has worked for me on my Windows 2000 + IE 6 computer at home, as well as my Windows XP + Multiple IE computer at work.

Default access modifier - If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes).

#!/bin/sh
sed '1,2d' "$0"|$(which groovy) /dev/stdin; exit;

println("hello");

You could also create the input button in this way:

var button = '<input type="button" id="questionButton" value='+variable+'> <br />';

It might be the syntax of the Button creation that is off somehow.

Was the Tomcat running before you restarted it? Was there any other app listening on this port?

The exception is thrown because there was nobody listening on the command port (see <Server port="..." in $tomcat_home/conf/server.xml).

I came across this when I started using three.js as well. It's actually a javascript issue. You currently have:

renderer.setClearColorHex( 0x000000, 1 );

in your threejs init function. Change it to:

renderer.setClearColorHex( 0xffffff, 1 );

Update: Thanks to HdN8 for the updated solution:

renderer.setClearColor( 0xffffff, 0);

Update #2: As pointed out by WestLangley in another, similar question - you must now use the below code when creating a new WebGLRenderer instance in conjunction with the setClearColor() function:

var renderer = new THREE.WebGLRenderer({ alpha: true });

Update #3: Mr.doob points out that since r78 you can alternatively use the code below to set your scene's background colour:

var scene = new THREE.Scene(); // initialising the scene
scene.background = new THREE.Color( 0xff0000 );

Following is a free list of tools you can use to check, test and verify your JS code:

1. Google Code Playground
2. JavaScript Sandbox
3. jsbin
4. jsfiddle
5. pastebin
6. jsdo.it
7. firebug
8. html5snippet.net

Hope this helps.

The fastest way should be:

<%@ page import="java.util.Map" %>
Map<String, String[]> parameters = request.getParameterMap();
for (Map.Entry<String, String[]> entry : parameters.entrySet()) {
    if (entry.getKey().startsWith("question")) {
        String[] values = entry.getValue();
        // etc.

Note that you can't do:

for (Map.Entry<String, String[]> entry : 
     request.getParameterMap().entrySet()) { // WRONG!

for reasons explained here.

No, but you have a couple of options:

The easiest is to upload all the files you have into that directory you're in (i.e. the cPanel user home directory), and put the contents of public into public_html. That way your directory structure will be something like this (slightly messy but it works):

/
    .composer/
    .cpanel/
    ...
    app/                 <- your laravel app directory
    etc/
    bootstrap/           <- your laravel bootstrap directory
    mail/
    public_html/         <- your laravel public directory
    vendor/
    artisan              <- your project's root files

You may also need to edit bootstrap/paths.php to point at the correct public directory.

The other solution, if you don't like having all these files in that 'root' directory would be to put them in their own directory (maybe 'laravel') that's still in the root directory and then edit the paths to work correctly. You'll still need to put the contents of public in public_html, though, and this time edit your public_html/index.php to correctly bootstrap the application. Your folder structure will be a lot tidier this way (though there could be some headaches with paths due to messing with the framework's designed structure more):

/
    .composer/
    .cpanel/
    ...
    etc/
    laravel/      <- a directory containing all your project files except public
        app/
        bootstrap/
        vendor/
        artisan
    mail/
    public_html/  <- your laravel public directory

At the time of writing, most browsers did return properties in the same order as they were inserted, but it was explicitly not guaranteed behaviour so shouldn't have been relied upon.

The ECMAScript specification used to say:

The mechanics and order of enumerating the properties ... is not specified.

However in ES2015 and later non-integer keys will be returned in insertion order.

df$Gene <- as.factor(df$Gene)
do.call(rbind, lapply(split(df,df$Gene), function(x) {return(x[which.max(x$Value),])}))

Just using base R
