General Syntax:

7z a archive_name target parameters

Check your 7-Zip dir. Depending on the release you have, 7z may be replaced with 7za in the syntax.

Parameters:

• -p encrypt and prompt for PW.
• -pPUT_PASSWORD_HERE (this replaces -p) if you want to preset the PW with no prompt.
• -mhe=on to hide file structure, otherwise file structure and names will be visible by default.

Eg. This will prompt for a PW and hide file structures:

7z a archive_name target -p -mhe=on

Eg. No prompt, visible file structure:

7z a archive_name target -pPUT_PASSWORD_HERE

And so on. If you leave target blank, 7z will assume * in current directory and it will recurs directories by default.

I know it's an old question, but I just had to find solution for multiple rows update where multiple records had to updated with different values based on their IDs and I found that I can use a a scalar-subselect:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP='000030'

(with WHERE optional, of course)

Also, I found that it is critical to specify that no NULL values would not be used in this update (in case not all records in first table have corresponding record in the second one), this way:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP IN (SELECT EMPNO FROM EMPLOYEE)

Yes, it's possible with a bit of tweak. Unfortunately, you still have to have VS 2010 installed.

1. First, install XNA Game Studio 4.0. The easiest way is to install the Windows Phone SDK 7.1 which contains everything required.

2. Copy the XNA Game Extension from VS 10 to VS 11 by opening a command prompt 'as administrator' and executing the following (may vary if not x64 computer with defaults paths) :

   xcopy /e "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0" "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0"

3. Run notepad as administrator then open extension.vsixmanifest in the destination directory just created.

4. Upgrade the Supported product version to match the new version (or duplicate the whole VisualStudio element and change the Version attribute, as @brainslugs83 said in comments):

   <SupportedProducts>
     <VisualStudio Version="11.0">
       <Edition>VSTS</Edition>
       <Edition>VSTD</Edition>
       <Edition>Pro</Edition>
       <Edition>VCSExpress</Edition>
       <Edition>VPDExpress</Edition>
     </VisualStudio>
   </SupportedProducts>
   

5. Don't forget to clear/delete your cache in %localappdata%\Microsoft\VisualStudio\12.0\Extensions.

6. You may have to run the command to tells Visual Studio that new extensions are available. If you see an 'access denied' message, try launching the console as an administrator.

   "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" /setup
   

This has been tested for Windows Games, but not WP7 or Xbox games.

[Edit] According Jowsty, this works also for XBox 360 Games.

[Edit for Visual Studio 2013 & Windows 8.1] See here for documentation on installing Windows Phone SDK 7.1 on Windows 8.1. Use VS version number 12.0 in place of 11.0 for all of these steps, and they will still work correctly.

Assuming a Css class of "image" :

input.image { 
  background: url(/i/bg.png) no-repeat top left; 
  width: /* img-width */; 
  height: /* img-height */ 
}

If you don't know what the image width and height are, you can set this dynamically with javascript.

Try using Replace to see if it will work for you. The problem as I see it which has been mentioned a few times above is the CDate function is choking on the periods. You can use replace to change them to slashes. To answer your question about a Function in vba that can parse any date format, there is not any you have very limited options.

Dim current as Date, highest as Date, result() as Date 
For Each itemDate in DeliveryDateArray
    Dim tempDate As String
    itemDate = IIf(Trim(itemDate) = "", "0", itemDate) 'Added per OP's request.
    tempDate = Replace(itemDate, ".", "/")
    current = Format(CDate(tempDate),"dd/mm/yyyy")
    if current > highest then 
        highest = current 
    end if 
    ' some more operations an put dates into result array 
Next itemDate 
'After activating final sheet... 
Range("A1").Resize(UBound(result), 1).Value = Application.Transpose(result) 

Frankly I use a tcomment plugin for that link. It can handle almost every syntax. It defines nice movements, using it with some text block matchers specific for python makes it a powerful tool.

Just remove the slash after Data and prepend the root:

<xsl:variable name="myVarA" select="/root/DataSet/Data[@Value1='2']/@Value2"/>

For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).

theCanvas.onkeydown = function (e) {
    if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
        e.view.event.preventDefault();
    }
}

Why not simply do window.event.preventDefault()? MDN states:

window.event is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.

For MinGW this worked for me:

• Right click project, select Properties
• Go to C/C++ General - Paths and Symbols - Includes - GNU C++ - Include directories
• Select Add...
• Select Variables...
• Select MINGW_HOME and click OK
• Click Apply and OK

You should now see several MinGW paths in Includes in your project explorer.
The errors may not disappear instantly, you may need to refresh/build your project.

If you are using Cygwin, there could be an equivalent variable present.

Testing¹ reveals that Lightsail instances in fact are EC2 instances, from the t2 class of burstable instances.

EC2, of course, has many more instance families and classes other than the t2, almost all of which are more "powerful" (or better equipped for certain tasks) than these, but also much more expensive. But for meaningful comparisons, the 512 MiB Lightsail instance appears to be completely equivalent in specifications to the similarly-priced t2.nano, the 1GiB is a t2.micro, the 2 GiB is a t2.small, etc.

Lightsail is a lightweight, simplified product offering -- hard disks are fixed size EBS SSD volumes, instances are still billable when stopped, security group rules are much less flexible, and only a very limited subset of EC2 features and options are accessible.

It also has a dramatically simplified console, and even though the machines run in EC2, you can't see them in the EC2 section of the AWS console. The instances run in a special VPC, but this aspect is also provisioned automatically, and invisible in the console. Lightsail supports optionally peering this hidden VPC with your default VPC in the same AWS region, allowing Lightsail instances to access services like EC2 and RDS in the default VPC within the same AWS account.²

Bandwidth is unlimited, but of course free bandwidth is not -- however, Lightsail instances do include a significant monthly bandwidth allowance before any bandwidth-related charges apply.³ Lightsail also has a simplified interface to Route 53 with limited functionality.

But if those sound like drawbacks, they aren't. The point of Lightsail seems to be simplicity. The flexibility of EC2 (and much of AWS) leads inevitably to complexity. The target market for Lightsail appears to be those who "just want a simple VPS" without having to navigate the myriad options available in AWS services like EC2, EBS, VPC, and Route 53. There is virtually no learning curve, here. You don't even technically need to know how to use SSH with a private key -- the Lightsail console even has a built-in SSH client -- but there is no requirement that you use it. You can access these instances normally, with a standard SSH client.

¹Lightsail instances, just like "regular" EC2 (VPC and Classic) instances, have access to the instance metadata service, which allows an instance to discover things about itself, such as its instance type and availability zone. Lightsail instances are identified in the instance metadata as t2 machines.

²The Lightsail docs are not explicit about the fact that peering only works with your Default VPC, but this appears to be the case. If your AWS account was created in 2013 or before, then you may not actually have a VPC with the "Default VPC" designation. This can be resolved by submitting a support request, as I explained in Can't establish VPC peering connection from Amazon Lightsail (at Server Fault).

³The bandwidth allowance applies to both inbound and outbound traffic; after this total amount of traffic is exceeded, inbound traffic continues to be free, but outbound traffic becomes billable. See "What does data transfer cost?" in the Lightsail FAQ.

The chosen answer is a good answer, but be careful with the object returned.

string test = null;
string test2 = "";
if (test is string)
     Console.WriteLine("This will never be hit.");
if (test2 is string)
     Console.WriteLine("Always hit.");

Extrapolating...

string test = GetDefault(typeof(string));
if (test is string)
     Console.WriteLine("This will never be hit.");

If you are using AWS CLI on Windows, you can use the Measure-Object from PowerShell to get the total counts of files, just like wc -l on *nix.

PS C:\> aws s3 ls s3://mybucket/ --recursive | Measure-Object

Count    : 25
Average  :
Sum      :

Hope it helps.

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. Have a look at the docs https://docs.angularjs.org/api/ng/service/$http

Now the right way to use is:

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
});

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

A response status code between 200 and 299 is considered a success status and will result in the success callback being called.

Just in case... Simple Python script that clean Postgresql database

import psycopg2
import sys

# Drop all tables from a given database

try:
    conn = psycopg2.connect("dbname='akcja_miasto' user='postgres' password='postgres'")
    conn.set_isolation_level(0)
except:
    print "Unable to connect to the database."

cur = conn.cursor()

try:
    cur.execute("SELECT table_schema,table_name FROM information_schema.tables WHERE table_schema = 'public' ORDER BY table_schema,table_name")
    rows = cur.fetchall()
    for row in rows:
        print "dropping table: ", row[1]   
        cur.execute("drop table " + row[1] + " cascade") 
    cur.close()
    conn.close()        
except:
    print "Error: ", sys.exc_info()[1]

Make sure that after copying it the indentation is right since Python relies on it.

It's all about context, and also who is responsible for handling duplicates in requests (server or client or both)

If server just point the duplicate, look at 4xx:

• 400 Bad Request - when the server will not process a request because it's obvious client fault
• 409 Conflict - if the server will not process a request, but the reason for that is not the client's fault
• ...

For implicit handling of duplicates, look at 2XX:

• 200 OK
• 201 Created
• ...

if the server is expected to return something, look at 3XX:

• 302 Found
• 303 See Other
• ...

when the server is able to point the existing resource, it implies a redirection.

If the above is not enough, it's always a good practice to prepare some error message in the body of the response.

I am using Git Bash on Win7. The following worked for me.

Create a config file at ~/.ssh/config or c:/users/[your_user_name]/.ssh/config. In the file enter:

Host your_host.com
     IdentityFile [absolute_path_to_your_.ssh]\id_rsa

I guess the host has to be a URL and not just a "name" or ref for your host. For example,

Host github.com
     IdentityFile c:/users/[user_name]/.ssh/id_rsa

The path can also be written in /c/users/[user_name]/.... format

The solution provided by Giordano Scalzo is great too. https://stackoverflow.com/a/9149518/1738546

Two possible approaches.

1. If you have a foreign key, declare it as on-delete-cascade and delete the parent rows older than 30 days. All the child rows will be deleted automatically.

2. Based on your description, it looks like you know the parent rows that you want to delete and need to delete the corresponding child rows. Have you tried SQL like this?

     delete from child_table
         where parent_id in (
              select parent_id from parent_table
                   where updd_tms != (sysdate-30)
   

   -- now delete the parent table records

   delete from parent_table
   where updd_tms != (sysdate-30);
   

---- Based on your requirement, it looks like you might have to use PL/SQL. I'll see if someone can post a pure SQL solution to this (in which case that would definitely be the way to go).

declare
    v_sqlcode number;
    PRAGMA EXCEPTION_INIT(foreign_key_violated, -02291);
begin
    for v_rec in (select parent_id, child id from child_table
                         where updd_tms != (sysdate-30) ) loop

    -- delete the children
    delete from child_table where child_id = v_rec.child_id;

    -- delete the parent. If we get foreign key violation, 
    -- stop this step and continue the loop
    begin
       delete from parent_table
          where parent_id = v_rec.parent_id;
    exception
       when foreign_key_violated
         then null;
    end;
 end loop;
end;
/

Put in the URL bar and then click enter:

javascript:alert(document.title);

You can select and copy the text from the alert depending on the website and the web browser you are using.

This is a stab in the dark, but maybe do you need to wrap your JSON arguments; like say something like this:

data: "{'Ids':[{'Id1':'2'},{'Id2':'2'}]}"

Make sure your JSON is properly formed?

This is years later, working on a legacy site... For the life of me I couldn't get the ->andWhere() or ->expr()->in() solutions working.

Finally looked in the Doctrine mongodb-odb repo and found some very revealing tests:

public function testQueryWhereIn()
{ 
  $qb = $this->dm->createQueryBuilder('Documents\User');
  $choices = array('a', 'b');
  $qb->field('username')->in($choices);
  $expected = [
    'username' => ['$in' => $choices],
  ];
  $this->assertSame($expected, $qb->getQueryArray());
}

It worked for me!

You can find the tests on github here. Useful for clarifying all sorts of nonsense.

Note: My setup is using Doctrine MongoDb ODM v1.0.dev as far as i can make out.

You can do something like this:

public class Example
{
    public String name;
    public String location;

    public String[] getExample()
    {
        String ar[] = new String[2];
        ar[0]= name;
        ar[1] =  location;
        return ar; //returning two values at once
    }
}

A single branch of another repository can be easily placed under a subdirectory retaining its history. For example:

git subtree add --prefix=rails git://github.com/rails/rails.git master

This will appear as a single commit where all files of Rails master branch are added into "rails" directory. However the commit's title contains a reference to the old history tree:

Add 'rails/' from commit <rev>

Where <rev> is a SHA-1 commit hash. You can still see the history, blame some changes.

git log <rev>
git blame <rev> -- README.md

Note that you can't see the directory prefix from here since this is an actual old branch left intact. You should treat this like a usual file move commit: you will need an extra jump when reaching it.

# finishes with all files added at once commit
git log rails/README.md

# then continue from original tree
git log <rev> -- README.md

There are more complex solutions like doing this manually or rewriting the history as described in other answers.

The git-subtree command is a part of official git-contrib, some packet managers install it by default (OS X Homebrew). But you might have to install it by yourself in addition to git.

To both style the hover color and avoid the OS default color in Firefox, you need to add a box-shadow to both the select option and select option:hover declarations, setting the color of the box-shadow on "select option" to the menu background color.

select option {
  background: #f00; 
  color: #fff; 
  box-shadow: inset 20px 20px #f00
} 

select option:hover {
  color: #000; 
  box-shadow: inset 20px 20px #00f;
}

In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

Spring 3.1. introduced the ResourceHandlerRegistry to configure ResourceHttpRequestHandlers for serving static resources from the classpath, the WAR, or the file system. We can configure the ResourceHandlerRegistry programmatically inside our web context configuration class.

• we have added the /js/** pattern to the ResourceHandler, lets include the foo.js resource located in the webapp/js/ directory
• we have added the /resources/static/** pattern to the ResourceHandler, lets include the foo.html resource located in the webapp/resources/ directory

@Configuration
@EnableWebMvc
public class StaticResourceConfiguration implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        System.out.println("WebMvcConfigurer - addResourceHandlers() function get loaded...");
        registry.addResourceHandler("/resources/static/**")
                .addResourceLocations("/resources/");

        registry
            .addResourceHandler("/js/**")
            .addResourceLocations("/js/")
            .setCachePeriod(3600)
            .resourceChain(true)
            .addResolver(new GzipResourceResolver())
            .addResolver(new PathResourceResolver());
    }
}

XML Configuration

<mvc:annotation-driven />
  <mvc:resources mapping="/staticFiles/path/**" location="/staticFilesFolder/js/"
                 cache-period="60"/>

Spring Boot MVC Static Content if the file is located in the WAR’s webapp/resources folder.

spring.mvc.static-path-pattern=/resources/static/**

And according to the wiki the Thrift runtime doesn't run on Windows.

Better way to use like,

<link rel="stylesheet" href="{{asset('assets/libraries/css/app.css')}}">

i would recommend using a MaterialButton, than you can do it like this:

new MaterialButton( 
 height: 40.0, 
 minWidth: 70.0, 
 color: Theme.of(context).primaryColor, 
 textColor: Colors.white, 
 child: new Text("push"), 
 onPressed: () => {}, 
 splashColor: Colors.redAccent,
)

The first one adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.

The second replaces the current history item so you can't go back to it.

See window.location:

• assign(url): Load the document at the provided URL.

• replace(url): Replace the current document with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

window.location.href = url;

is favoured over:

window.location = url;

The question is little unclear because the title of the question is asking about string and set conversion but then the question at the end asks how do I serialize ? !

let me refresh the concept of Serialization is the process of encoding an object, including the objects it refers to, as a stream of byte data.

If interested to serialize you can use:

json.dumps  -> serialize
json.loads  -> deserialize

If your question is more about how to convert set to string and string to set then use below code (it's tested in Python 3)

String to Set

set('abca')

Set to String

''.join(some_var_set)

example:

def test():
    some_var_set=set('abca')
    print("here is the set:",some_var_set,type(some_var_set))
    some_var_string=''.join(some_var_set)    
    print("here is the string:",some_var_string,type(some_var_string))

test()

Here is an alternative that works also

public final class Storage : AnyObject {

    var object:Any?

    public init(_ object:Any) {
        self.object = object
    }
}

extension Date {

    private static let associationMap = NSMapTable<NSString, AnyObject>()
    private struct Keys {
        static var Locale:NSString = "locale"
    }

    public var locale:Locale? {
        get {

            if let storage = Date.associationMap.object(forKey: Keys.Locale) {
                return (storage as! Storage).object as? Locale
            }
            return nil
        }
        set {
            if newValue != nil {
                Date.associationMap.setObject(Storage(newValue), forKey: Keys.Locale)
            }
        }
    }
}



var date = Date()
date.locale = Locale(identifier: "pt_BR")
print( date.locale )

As others have pointed out, you should use zipfile. The documentation tells you what functions are available, but doesn't really explain how you can use them to zip an entire directory. I think it's easiest to explain with some example code:

#!/usr/bin/env python
import os
import zipfile

def zipdir(path, ziph):
    # ziph is zipfile handle
    for root, dirs, files in os.walk(path):
        for file in files:
            ziph.write(os.path.join(root, file), os.path.relpath(os.path.join(root, file), os.path.join(path, '..')))
  
if __name__ == '__main__':
    zipf = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)
    zipdir('tmp/', zipf)
    zipf.close()

You cannot add JavaScript variable to HTML code.

For this you need to do in following way.

<html>
<head>
<script type="text/javscript">
var number = 123;

document.addEventListener('DOMContentLoaded', function() {
   document.getElementByTagName("h1").innerHTML("the value for number is: " + number);
});
</script>
</head>
<body>
<h1></h1>
</body>
</html>

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

Running the @neverever415 answer I got:

In this case check that you wrote a right package name, maybe it is a debug version like com.package_name.debug:

adb shell pm uninstall com.package_name.debug

It's trying to connect to the computer it's running on on port 5000, but the connection is being refused. Are you sure you have a server running?

If not, you can use netcat for testing:

nc -l -k -p 5000

Some implementations may require you to omit the -p flag.

In SQL Server type:

Select 'Your Text'

There is no need for the FROM or WHERE clause.

and the convolution is defined through a multiplication in transform domain:

conv2(x,y) = fftshift(ifft2(fft2(x).*fft2(y)))

if one channel is considered... for more channels this has to be done every channel

Just keep going with your code - you're on the right track:

//call SQL helper class to get initial data 
DataTable dt = sql.ExecuteDataTable("sp_MyProc");

dt.Columns.Add("NewColumn", typeof(System.Int32));

foreach(DataRow row in dt.Rows)
{
    //need to set value to NewColumn column
    row["NewColumn"] = 0;   // or set it to some other value
}

// possibly save your Dataset here, after setting all the new values

The way a select box is rendered is determined by the browser itself. So every browser will show you the height of the option list box in another height. You can't influence that. The only way you can change that is to make an own select from the scratch.

Because you did not write a comparison operator for your struct. The compiler does not generate it for you, so if you want comparison, you have to write it yourself.

I like this method:

import datetime, time

dts = datetime.datetime.utcnow()
epochtime = round(time.mktime(dts.timetuple()) + dts.microsecond/1e6)

The other methods posted here are either not guaranteed to give you UTC on all platforms or only report whole seconds. If you want full resolution, this works, to the micro-second.

A very silly mistake which could be possible resulting is adding of space at the start of the JDBC URL connection.

What I mean is:-

suppose u have bymistake given the jdbc url like

String jdbcUrl=" jdbc:mysql://localhost:3306/web_customer_tracker?useSSL=false&serverTimeZone=UTC";

(Notice there is a space in the staring of the url, this will make the error)

the correct way should be:

String jdbcUrl="jdbc:mysql://localhost:3306/web_customer_tracker?useSSL=false&serverTimeZone=UTC";

(Notice no space in the staring, you may give space at the end of the url but it is safe not to)

I'd recommend getting the source with urllib and, if you're going to parse, use something like Beautiful Soup.

import urllib

url = urllib.urlopen("http://example.com") # Open the URL.
content = url.readlines() # Read the source and save it to a variable.

Right click properties, Application tab, then see the assembly name and default namespace

Try trigger on logon

Insted of trying disconnect users you should not allow them to connect.

There is and example of such trigger.

CREATE OR REPLACE TRIGGER rds_logon_trigger

The short answer

Use the source command.

An example using source

For example:

config.sh

#!/usr/bin/env bash
production="liveschool_joe"
playschool="playschool_joe"
echo $playschool

script.sh

#!/usr/bin/env bash
source config.sh
echo $production

Note that the output from sh ./script.sh in this example is:

~$ sh ./script.sh 
playschool_joe
liveschool_joe

This is because the source command actually runs the program. Everything in config.sh is executed.

Another way

You could use the built-in export command and getting and setting "environment variables" can also accomplish this.

Running export and echo $ENV should be all you need to know about accessing variables. Accessing environment variables is done the same way as a local variable.

To set them, say:

export variable=value

at the command line. All scripts will be able to access this value.

No, there is no type called "byte" in C++. What you want instead is unsigned char (or, if you need exactly 8 bits, uint8_t from <cstdint>, since C++11). Note that char is not necessarily an accurate alternative, as it means signed char on some compilers and unsigned char on others.

Here is an Actionscript version:

private var columnNumbers:Array = ['A', 'B', 'C', 'D', 'E', 'F' , 'G', 'H', 'I', 'J', 'K' ,'L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];

    private function getExcelColumnName(columnNumber:int) : String{
        var dividend:int = columnNumber;
        var columnName:String = "";
        var modulo:int;

        while (dividend > 0)
        {
            modulo = (dividend - 1) % 26;
            columnName = columnNumbers[modulo] + columnName;
            dividend = int((dividend - modulo) / 26);
        } 

        return columnName;
    }

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

Setting them later

If you don't know the number of the plots you are going to plot you can change the colours once you have plotted them retrieving the number directly from the plot using .lines, I use this solution:

Some random data

import matplotlib.pyplot as plt
import numpy as np

fig1 = plt.figure()
ax1 = fig1.add_subplot(111)


for i in range(1,15):
    ax1.plot(np.array([1,5])*i,label=i)

The piece of code that you need:

colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired   
colors = [colormap(i) for i in np.linspace(0, 1,len(ax1.lines))]
for i,j in enumerate(ax1.lines):
    j.set_color(colors[i])
  

ax1.legend(loc=2)

The result is the following:

Deleting all instances of *.exd resolved it for me.

Another post on this topic with a nice jQuery/Ajax/PHP solution:

One way to achieve it is to wrap your input in <form> tag and reset it.

I'm not considering attaching thr form to NgForm or FormControl either.

@Component({
  selector: 'form-component',
  template: `
    <form #form>
      <input type="file" placeholder="File Name" name="filename">
    </form>
    <button (click)="reset()">Reset</button>
`
})
class FormComponent {



  @ViewChild('form') form;


  reset() {
    this.form.nativeElement.reset()
  }
}

You could override your object's ToString() method:

public override string ToString ()
{
    return string.Format ("{0},{1},{2}", this.number, this.id, this.whatever);
}

Your new class:

public class TimeWatch {    
    long starts;

    public static TimeWatch start() {
        return new TimeWatch();
    }

    private TimeWatch() {
        reset();
    }

    public TimeWatch reset() {
        starts = System.currentTimeMillis();
        return this;
    }

    public long time() {
        long ends = System.currentTimeMillis();
        return ends - starts;
    }

    public long time(TimeUnit unit) {
        return unit.convert(time(), TimeUnit.MILLISECONDS);
    }
}

Usage:

    TimeWatch watch = TimeWatch.start();
    // do something
    long passedTimeInMs = watch.time();
    long passedTimeInSeconds = watch.time(TimeUnit.SECONDS);

Afterwards, the time passed can be converted to whatever format you like, with a calender for example

Greetz, GHad

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

import urllib2
for line in urllib2.urlopen("http://www.myhost.com/SomeFile.txt"):
    print line

Add the following line to the beginning script1.py

#!/usr/bin/env python

and then make the script executable:

$ chmod +x script1.py

If the script resides in a directory that appears in your PATH variable, you can simply type

$ script1.py

Otherwise, you'll need to provide the full path (either absolute or relative). This includes the current working directory, which should not be in your PATH.

$ ./script1.py

As for now there is no proper solution, as @spro says.

However, if you have an in-flight response and are using ReadableStream, you can close the stream to cancel the request.

fetch('http://example.com').then((res) => {
  const reader = res.body.getReader();

  /*
   * Your code for reading streams goes here
   */

  // To abort/cancel HTTP request...
  reader.cancel();
});

From JLS http://docs.oracle.com/javase/specs/jls/se5.0/html/arrays.html#10.2

Here are examples of declarations of array variables that do not create arrays:

int[ ] ai;          // array of int
short[ ][ ] as;         // array of array of short
Object[ ]   ao,     // array of Object
        otherAo;    // array of Object
Collection<?>[ ] ca;        // array of Collection of unknown type
short       s,      // scalar short 
        aas[ ][ ];  // array of array of short

Here are some examples of declarations of array variables that create array objects:

Exception ae[ ] = new Exception[3]; 
Object aao[ ][ ] = new Exception[2][3];
int[ ] factorial = { 1, 1, 2, 6, 24, 120, 720, 5040 };
char ac[ ] = { 'n', 'o', 't', ' ', 'a', ' ',
                 'S', 't', 'r', 'i', 'n', 'g' }; 
String[ ] aas = { "array", "of", "String", };

The [ ] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both, as in this example:

byte[ ] rowvector, colvector, matrix[ ];

This declaration is equivalent to:

byte rowvector[ ], colvector[ ], matrix[ ][ ];

Thanks to Chris Jester-Young I managed to make it work!

I think the way I managed to do it will work only on really simple projects:

• With Dex2jar I obtained the Jar.
• With jd-gui I convert my Jar back to Java files.

• With apktool i got the android manifest and the resources files.

• In Eclipse I create a new project with the same settings as the old one (checking all the information in the manifest file)

• When the project is created I'm replacing all the resources and the manifest with the ones I obtained with apktool
• I paste the java files I extracted from the Jar in the src folder (respecting the packages)
• I modify those files with what I need
• Everything is compiling!

/!\ be sure you removed the old apk from the device an error will be thrown stating that the apk signature is not the same as the old one!

I am assuming you are using java 7, thus you get a compiler warning, when you don't close the resource you should close your scanner usually in a finally block.

Scanner scanner = null;
try {
    scanner = new Scanner(System.in);
    //rest of the code
}
finally {
    if(scanner!=null)
        scanner.close();
}

Or even better: use the new Try with resource statement:

try(Scanner scanner = new Scanner(System.in)){
    //rest of your code
}

Firebase is a suite of features .

• Realtime Database
• Hosting
• Authentication
• Storage
• Cloud Messaging
• Remote Config
• Test Lab
• Crash Reporting
• Notifications
• App Indexing
• Dynamic Links
• Invites
• AdWords
• AdMob

I believe you are trying to compare Firebase Realtime Database with Mongo DB . Firebase Realtime Database stores data as JSON format and syncs to all updates of the data to all clients listening to the data . It abstracts you from all complexity that is needed to setup and scale any database . I will not recommend firebase where you have lot of complex scenarios where aggregation of data is needed .(Queries that need SUM/AVERAGE kind of stuff ) . Though this is recently achievable using Firebase functions . Modeling data in Firebase is tricky . But it is the best way to get you started instantaneously . MongoDB is a database. This give you lot of powerful features. But MongoDB when installed in any platform you need to manage it by yourself .

When i try to choose between Firebase or MongoDB(or any DB ) . I try to answer the following .

1. Are there many aggregation queries that gets executed .(Like in case of reporting tool or BI tool ) . If Yes dont go for Firebase
2. Do i need to perform lot of transaction . (If yes then i would not like to go with firebase) (Tranactions are somewhat easy though after introduction of functions but that is also a overhead if lot of transactions needs to be maintained)
3. What timeline do i have to get things up and running .(Firebase is very easy to setup and integrate ).
4. Do i have expertise to scale up the DB and trouble shoot DB related stuffs . (Firebase is more like SAAS so no need to worry about scaleability)

This is an improve of @ComFreek ans:

<form id="myform">
  <!-- form elements -->
  <a href="javascript:;" onclick="document.getElementById('myform').submit()">Submit</a>
</form>

So the will not trigger action and reload your page. Specially if your are developing with a framework with SPA.

Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).

javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456

Then load the properties to your environment from your code. This makes your application configurable.

FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);

This should not happen. Can you try doing this? Use the system properties and set the property as below:

Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", "10.101.3.229");

And if you have a port associated, then set this as well.

properties.setProperty("mail.smtp.port", "8080");

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

Have you tried this?

<appSettings>  
  <add key="myurl" value="http://www.myurl.com?&amp;cid=&amp;sid="/>
<appSettings>

The provided solutions do resolve the issue. However, they also impact all other textarea elements with the same styling. I had to solve this and just created a more specific selector. Here is what I came up with to prevent invasive changes.

.modal-content textarea.form-control {
    max-width: 100%;
}

While this selector may seem aggressive. It helps restrain the textarea into the content area of the modal itself.

Additionally, the min-width solution presented, above, works with basic bootstrap modals, though I had issues when using it with angular-ui-bootstrap modals.

underscore.js is using the following

toString = Object.prototype.toString;

_.isArray = nativeIsArray || function(obj) {
    return toString.call(obj) == '[object Array]';
  };

_.isObject = function(obj) {
    return obj === Object(obj);
  };

_.isFunction = function(obj) {
    return toString.call(obj) == '[object Function]';
  };

Bottom line: A module is a cross between a static/utility class and a mixin.

Mixins are reusable pieces of "partial" implementation, that can be combined (or composed) in a mix & match fashion, to help write new classes. These classes can additionally have their own state and/or code, of course.

As of year 2020, JetBrains suggests to commit the .idea folder.
The JetBrains IDEs (webstorm, intellij, android studio, pycharm, clion, etc.) automatically add that folder to your git repository (if there's one).
Inside the folder .idea, has been already created a .gitignore, updated by the IDE itself to avoid to commit user related settings that may contains privacy/password data.

It is safe (and usually useful) to commit the .idea folder.

True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.

Don't make it an Array if it is not an Array, make it an object:

var saveData = {};
saveData.a = 2;
saveData.c = 1;

// equivalent to...
var saveData = {a: 2, c: 1}

// equivalent to....
var saveData = {};
saveData['a'] = 2;
saveData['c'] = 1;

Doing it the way you are doing it with Arrays is just taking advantage of Javascript's treatment of Arrays and not really the right way of doing it.

IN HTML 5 action="" IS NOT SUPPORTED SO DON'T DO THIS. BAD PRACTICE.

If instead you completely negate action altogether it will submit to the same page by default, I believe this is the best practice:

<form>This will submit to the current page</form>

If you are sumbitting the form using php you may want to consider the following. read more about it here.

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

Alternatively you could use # bear in mind though that this will act like an anchor and scroll to the top of the page.

<form action="#">

You will have to annotate your service with @Service since you have said I am using annotations for mapping

How about using the wsdl /server or wsdl /serverinterface switches? As far as I understand the wsdl.exe command line properties, that's what you're looking for.

- ADVANCED -

/server

Server switch has been deprecated. Please use /serverInterface instead.
Generate an abstract class for an xml web service implementation using
ASP.NET based on the contracts. The default is to generate client proxy
classes.

On the other hand: why do you want to create obsolete technology solutions? Why not create this web service as a WCF service. That's the current and more modern, much more flexible way to do this!

Marc

UPDATE:

When I use wsdl /server on a WSDL file, I get this file created:

[WebService(Namespace="http://.......")]
public abstract partial class OneCrmServiceType : System.Web.Services.WebService 
{
    /// <remarks/>
    [WebMethod]
    public abstract void OrderCreated(......);
}

This is basically almost exactly the same code that gets generated when you add an ASMX file to your solution (in the code behind file - "yourservice.asmx.cs"). I don't think you can get any closer to creating an ASMX file from a WSDL file.

You can always add the "yourservice.asmx" manually - it doesn't really contain much:

<%@ WebService Language="C#" CodeBehind="YourService.asmx.cs" 
      Class="YourServiceNamespace.YourServiceClass" %>

When the user session times out, I send back an HTTP 204 status code. Note that the HTTP 204 status contains no content. On the client-side I do this:

xhr.send(null);
if (xhr.status == 204) 
    Reload();
else 
    dropdown.innerHTML = xhr.responseText;

Here is the Reload() function:

function Reload() {
    var oForm = document.createElement("form");
    document.body.appendChild(oForm);
    oForm.submit();
    }

Not sure if you are coding these programs, but this is a simple example of how you'd do it.

program1.c

#include <stdio.h>
int main (int argc, char * argv[] ) {
    printf("%s", argv[1]); 
    return 0;
}

rgx.cpp

#include <cstdio>
#include <regex>
#include <iostream>
using namespace std;
int main (int argc, char * argv[] ) {
    char input[200];
    fgets(input,200,stdin);
    string s(input)
    smatch m;
    string reg_exp(argv[1]);
    regex e(reg_exp);
    while (regex_search (s,m,e)) {
      for (auto x:m) cout << x << " ";
      cout << endl;
      s = m.suffix().str();
    }
    return 0;
}

Compile both then run program1.exe "this subject has a submarine as a subsequence" | rgx.exe "\b(sub)([^ ]*)"

The | operator simply redirects the output of program1's printf operation from the stdout stream to the stdin stream whereby it's sitting there waiting for rgx.exe to pick up.

Range("$A$1").Value = "'01/01/13 00:00" will do it.

Note the single quote; this will defeat automatic conversion to a number type. But is that what you really want? An alternative would be to format the cell to take a date-time value. Then drop the single quote from the string.

Try this

$date = Carbon::parse(date_format($youttimestring,'d/m/Y H:i:s'));
echo $date;

Use @Named to differentiate between different objects of the same type bound in the same scope.

@Named("maxWaitTime")
public long maxWaitTimeMs;

@Named("minWaitTime")
public long minWaitTimeMs;

Without the @Named qualifier, the injector would not know which long to bind to which variable.

• If you want to create annotations that act like @Named, use the @Qualifier annotation when creating them.

• If you look at @Named, it is itself annotated with @Qualifier.

#container-of-boxes {
    display: table;
    width: 1158px;
}
#box-1 {
    width: 578px;
}
#box-2 {
    width: 386px;
}
#box-3 {
    width: 194px;
}
#box-1, #box-2, #box-3 {
    min-height: 210px;
    padding-bottom: 20px;
    display: table-cell;
    height: auto;
    overflow: hidden;
}

• The container must have display:table
• The boxes inside container must be: display:table-cell
• Don't put floats.

To change the size of (almost) all text elements, in one place, and synchronously, rel() is quite efficient:
g+theme(text = element_text(size=rel(3.5))

You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)), strip.text.x = element_text(size=rel(3.5)), strip.text.y = element_text(size=rel(3.5)))

I believe pwdencrypt is using a hash so you cannot really reverse the hashed string - the algorithm is designed so it's impossible.

If you are verifying the password that a user entered the usual technique is to hash it and then compare it to the hashed version in the database.

This is how you could verify a usered entered table

SELECT password_field FROM mytable WHERE password_field=pwdencrypt(userEnteredValue)

Replace userEnteredValue with (big surprise) the value that the user entered :)

You could use Spring AOP aproach. For example if you have some service, that needs to know current principal. You could introduce custom annotation i.e. @Principal , which indicate that this Service should be principal dependent.

public class SomeService {
    private String principal;
    @Principal
    public setPrincipal(String principal){
        this.principal=principal;
    }
}

Then in your advice, which I think needs to extend MethodBeforeAdvice, check that particular service has @Principal annotation and inject Principal name, or set it to 'ANONYMOUS' instead.

The unwanted side effects of simple folder delete or installing over existing installation have been removed by a script written by Kyle Fuller - deintegrate and here is the proper workflow:

1. Install clean:

   $ sudo gem install cocoapods-clean
   

2. Run deintegrate in the folder of the project:

   $ pod deintegrate
   

3. Clean (this tool is no longer available):

   $ pod clean
   

4. Modify your podfile (delete the lines with the pods you don't want to use anymore) and run:

   $ pod install
   

Done.

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Thanks for the input. Tried the stuff that has been mentioned here and these are the 2 I got to work:

(
select 'OK', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
AND TimeStamp>'2009-02-12 18:00:00'
AND (BoolField05=1)
)
UNION
(
select 'DEL', * from WorkItems t1
where exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
AND TimeStamp>'2009-02-12 18:00:00'
AND NOT (BoolField05=1)
)

AND

select 
    case
        when
            (BoolField05=1)
    then 'OK'
    else 'DEL'
        end,
        *
from WorkItems t1
Where
            exists(select 1 from workitems t2 where t1.TextField01=t2.TextField01 AND (BoolField05=1) )
            AND TimeStamp=(select max(t2.TimeStamp) from workitems t2 where t2.TextField01=t1.TextField01) 
            AND TimeStamp>'2009-02-12 18:00:00'

Which would be the most efficient of these (edit: the second as it only scans the table once), and is it possible to make it even more efficient? (The BoolField=1) is really a variable (dyn sql) that can contain any where statement on the table.

I am running on MS SQL 2005. Tried Quassnoi examples but did not work as expected.

From the Android Developers page,

onPause():

Called when the system is about to start resuming a previous activity. This is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, etc. Implementations of this method must be very quick because the next activity will not be resumed until this method returns. Followed by either onResume() if the activity returns back to the front, or onStop() if it becomes invisible to the user.

onStop():

Called when the activity is no longer visible to the user, because another activity has been resumed and is covering this one. This may happen either because a new activity is being started, an existing one is being brought in front of this one, or this one is being destroyed. Followed by either onRestart() if this activity is coming back to interact with the user, or onDestroy() if this activity is going away.

Now suppose there are three Activities and you go from A to B, then onPause of A will be called now from B to C, then onPause of B and onStop of A will be called.

The paused Activity gets a Resume and Stopped gets Restarted.

When you call this.finish(), onPause-onStop-onDestroy will be called. The main thing to remember is: paused Activities get Stopped and a Stopped activity gets Destroyed whenever Android requires memory for other operations.

I hope it's clear enough.

Here is short example of how serialization works. I was also learning about the same and I found two links useful. What Serialization is and how it can be done in .NET.

A sample program explaining serialization

If you don't understand the above program a much simple program with explanation is given here.

BitmapFactory.Options options=new BitmapFactory.Options();
            options.inSampleSize = 10;
            FixBitmap = BitmapFactory.decodeFile(ImagePath, options);
            //FixBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.gv);

           byteArrayOutputStream = new ByteArrayOutputStream();
           FixBitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream); //compress to 50% of original image quality
           byteArray = byteArrayOutputStream.toByteArray();

           ConvertImage = Base64.encodeToString(byteArray, Base64.DEFAULT);

That is because you are not fully qualifying your cells object. Try this

With Worksheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

Notice the DOT before Cells?

Private Sub Worksheet_Change(ByVal Target As Range)
vNEW = Target.Value
aNEW = Target.Address
Application.EnableEvents = False
Application.Undo
vOLD = Target.Value
Target.Value = vNEW
Application.EnableEvents = True
End Sub

I know this is an old post, but thought this could be useful. If you have a need to ignore specific packages during the update process (like any packages that update JavaScript references), use the following PowerShell script (make sure your package source is set to "All" in Package Manager Console):

EDIT 2014-09-25 10:55 AM EST - Fixed a bug in the script

$packagePath = "packages.config"
$projectName = "MyProjectName"

$packagesToIgnore = @(
    "bootstrap",
    "jQuery",
    "jquery-globalize",
    "jquery.mobile",
    "jQuery.jqGrid",
    "jQuery.UI.Combined",
    "jQuery.Validation",
    "Microsoft.jQuery.Unobtrusive.Validation",
    "Modernizr",
    "Moment.js"
)

[xml]$packageFile = gc $packagePath
$packagesToProcess = $packageFile.packages.package | Where-Object {$packagesToIgnore -notcontains $_.id}

$packagesToProcess | % { Update-Package -reinstall -projectname $projectName -id $($_.id) }

$('.DataTables_sort_wrapper').trigger("click");

you can't initialise var with null, var needs to be initialised as a type otherwise it cannot be inferred, if you think you need to do this maybe you can post the code it is probable that there is another way to do what you are attempting.

The entire transmission, including the query string, the whole URL, and even the type of request (GET, POST, etc.) is encrypted when using HTTPS.

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

For any of you calling back to the same server for your IFRAME, pass this simple header inside the IFRAME page:

Content-Security-Policy: frame-ancestors 'self'

Or, add this to your web server's CSP configuration.

I believe the simplest answer is

list.reduce(:+).to_f / list.size

unsigned char* is basically a byte array and should be used to represent raw data rather than a string generally. A unicode string would be represented as wchar_t*

According to the C++ standard a reinterpret_cast between unsigned char* and char* is safe as they are the same size and have the same construction and constraints. I try to avoid reintrepret_cast even more so than const_cast in general.

If static cast fails with what you are doing you may want to reconsider your design because frankly if you are using C++ you may want to take advantage of what the "plus plus" part offers and use string classes and STL (aka std::basic_string might work better for you)

you must be using old version of wget i had same issue. i was using wget 1.12.so to solve this issue there are 2 way: Update wget or use curl

curl -LO 'https://example.com/filename.tar.gz'

recordId is property of the object

@Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Nai_record other = (Nai_record) obj;
        if (recordId == null) {
            if (other.recordId != null)
                return false;
        } else if (!recordId.equals(other.recordId))
            return false;
        return true;
    }

I am a big fan of DB4O for both .Net and Java.

Performance has become much better since the early releases. The licensing model isnt too bad, either. I particularly like the options available for querying your objects. Query by example is very powerful and easy to get used to.

In one line:

String niceFormattedJson = JsonWriter.formatJson(jsonString)

The json-io libray (https://github.com/jdereg/json-io) is a small (75K) library with no other dependencies than the JDK.

In addition to pretty-printing JSON, you can serialize Java objects (entire Java object graphs with cycles) to JSON, as well as read them in.

Write the process as a server-side script in whatever language (php/bash/perl/etc) is handy and then call it from the process control functions in your php script.

The function probably detects if standard io is used as the output stream and if it is then that will set the return value..if not then it ends

proc_close( proc_open( "./command --foo=1 &", array(), $foo ) );

I tested this quickly from the command line using "sleep 25s" as the command and it worked like a charm.

(Answer found here)

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

Use System.currentTimeMillis() or System.nanoTime() if you want even more precise reading. Usually, milliseconds is precise enough if you need to output the value to the user. Moreover, System.nanoTime() may return negative values, thus it may be possible that, if you're using that method, the return value is not correct.

A general and wide use would be to use milliseconds :

long start = System.currentTimeMillis();

... 


long end = System.currentTimeMillis();

NumberFormat formatter = new DecimalFormat("#0.00000");
System.out.print("Execution time is " + formatter.format((end - start) / 1000d) + " seconds");

Note that nanoseconds are usually used to calculate very short and precise program executions, such as unit testing and benchmarking. Thus, for overall program execution, milliseconds are preferable.

using ng-keyup directive in angularJS, only send a message on pressing Enter key and Shift+Enter will just take a new line.

ng-keyup="($event.keyCode == 13&&!$event.shiftKey) ? sendMessage() : null"

Here is my solution which does not allocate any heap memory, therefore it should be significantly faster than most of the other implementations mentioned here.

public static int indexOfIgnoreCase(final String haystack,
                                    final String needle) {
    if (needle.isEmpty() || haystack.isEmpty()) {
        // Fallback to legacy behavior.
        return haystack.indexOf(needle);
    }

    for (int i = 0; i < haystack.length(); ++i) {
        // Early out, if possible.
        if (i + needle.length() > haystack.length()) {
            return -1;
        }

        // Attempt to match substring starting at position i of haystack.
        int j = 0;
        int ii = i;
        while (ii < haystack.length() && j < needle.length()) {
            char c = Character.toLowerCase(haystack.charAt(ii));
            char c2 = Character.toLowerCase(needle.charAt(j));
            if (c != c2) {
                break;
            }
            j++;
            ii++;
        }
        // Walked all the way to the end of the needle, return the start
        // position that this was found.
        if (j == needle.length()) {
            return i;
        }
    }

    return -1;
}

And here are the unit tests that verify correct behavior.

@Test
public void testIndexOfIgnoreCase() {
    assertThat(StringUtils.indexOfIgnoreCase("A", "A"), is(0));
    assertThat(StringUtils.indexOfIgnoreCase("a", "A"), is(0));
    assertThat(StringUtils.indexOfIgnoreCase("A", "a"), is(0));
    assertThat(StringUtils.indexOfIgnoreCase("a", "a"), is(0));

    assertThat(StringUtils.indexOfIgnoreCase("a", "ba"), is(-1));
    assertThat(StringUtils.indexOfIgnoreCase("ba", "a"), is(1));

    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", " Royal Blue"), is(-1));
    assertThat(StringUtils.indexOfIgnoreCase(" Royal Blue", "Royal Blue"), is(1));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "royal"), is(0));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "oyal"), is(1));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "al"), is(3));
    assertThat(StringUtils.indexOfIgnoreCase("", "royal"), is(-1));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", ""), is(0));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "BLUE"), is(6));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "BIGLONGSTRING"), is(-1));
    assertThat(StringUtils.indexOfIgnoreCase("Royal Blue", "Royal Blue LONGSTRING"), is(-1));  
}

As TASKKILL might be unavailable on some Home/basic editions of windows here some alternatives:

TSKILL processName

or

TSKILL PID

Have on mind that processName should not have the .exe suffix and is limited to 18 characters.

Another option is WMIC :

wmic Path win32_process Where "Caption Like 'MyProcess.exe'" Call Terminate

wmic offer even more flexibility than taskkill .With wmic Path win32_process get you can see the available fileds you can filter.

Ideally these would go in a class called "FileNaming" or maybe just rename Encode to "FileNameEncode". Note: these are not designed to handle Full Paths, just the folder and/or file names. Ideally you would Split("/") your full path first and then check the pieces. And obviously instead of a union, you could just add the "%" character to the list of chars not allowed in Windows, but I think it's more helpful/readable/factual this way. Decode() is exactly the same but switches the Replace(Uri.HexEscape(s[0]), s) "escaped" with the character.

public static List<string> urlEncodedCharacters = new List<string>
{
  "/", "\\", "<", ">", ":", "\"", "|", "?", "%" //and others, but not *
};
//Since this is a superset of urlEncodedCharacters, we won't be able to only use UrlEncode() - instead we'll use HexEncode
public static List<string> specialCharactersNotAllowedInWindows = new List<string>
{
  "/", "\\", "<", ">", ":", "\"", "|", "?", "*" //windows dissallowed character set
};

    public static string Encode(string fileName)
    {
        //CheckForFullPath(fileName); // optional: make sure it's not a path?
        List<string> charactersToChange = new List<string>(specialCharactersNotAllowedInWindows);
        charactersToChange.AddRange(urlEncodedCharacters.
            Where(x => !urlEncodedCharacters.Union(specialCharactersNotAllowedInWindows).Contains(x)));   // add any non duplicates (%)

        charactersToChange.ForEach(s => fileName = fileName.Replace(s, Uri.HexEscape(s[0])));   // "?" => "%3f"

        return fileName;
    }

I found this question because I wanted to do the same as the OP. I would like to add the following observation:

The iterative way (user225312, Sven Marnach):

list2 = [x for x in list1 if x]

Will return a list object in python3 and python2 . Instead the filter way (lunaryorn, Imran) will differently behave over versions:

list2 = filter(None, list1)

It will return a filter object in python3 and a list in python2 (see this question found at the same time). This is a slight difference but it must be take in account when developing compatible scripts.

This does not make any assumption about performances of those solutions. Anyway the filter object can be reverted to a list using:

list3 = list(list2)

do-while is better if the compiler isn't competent at optimization. do-while has only a single conditional jump, as opposed to for and while which have a conditional jump and an unconditional jump. For CPUs which are pipelined and don't do branch prediction, this can make a big difference in the performance of a tight loop.

Also, since most compilers are smart enough to perform this optimization, all loops found in decompiled code will usually be do-while (if the decompiler even bothers to reconstruct loops from backward local gotos at all).

I will let the code speak for itself:

Mesh mesh = new Mesh();
BoundingVolume vol = new BoundingVolume();
mesh.boundingVolume = vol;
vol.mesh = mesh;
vol.compute(); 

Do you like it? Here is with the setters:

Mesh mesh = new Mesh();
BoundingVolume vol = new BoundingVolume();
mesh.setBoundingVolume(vol);

Individual element copy, it seems to work for me with just a simple example.

maps := map[string]int {
    "alice":12,
    "jimmy":15,
}

maps2 := make(map[string]int)
for k2,v2 := range maps {
    maps2[k2] = v2
}

maps2["miki"]=rand.Intn(100)

fmt.Println("maps: ",maps," vs. ","maps2: ",maps2)

As the other answers stated, you can place .gitignore within any directory in a Git repository. However, if you need to have a private version of .gitignore, you can add the rules to .git/info/exclude file.

In a generic sense an webservice IS a API over HTTP. They often utilize JSON or XML, but there are some other approaches as well.

setup.py is Python's answer to a multi-platform installer and make file.

If you’re familiar with command line installations, then make && make install translates to python setup.py build && python setup.py install.

Some packages are pure Python, and are only byte compiled. Others may contain native code, which will require a native compiler (like gcc or cl) and a Python interfacing module (like swig or pyrex).

For Windows, you can check the Java home location. If it contains (x86) it is 32-bit otherwise 64-bit:

public static boolean is32Bit()
{
    val javaHome = System.getProperty("java.home");
    return javaHome.contains("(x86)");
}

public static boolean is64Bit()
{
    return !is32Bit();
}

Example paths:

C:\Program Files (x86)\Java\jdk1.8.0_181\bin\java.exe # 32-bit
C:\Program Files\Java\jdk-10.0.2\bin\java.exe # 64-bit

Why care about a Windows only solution?

If you need to know which bit version you're running on, you're likely fiddling around with native code on Windows so platform-independence is out of the window anyway.

(if your Python client code is also running under Windows)

Found a npm package that makes this easy with RxJS as a service.

https://www.npmjs.com/package/ng2-simple-timer

You can 'subscribe' to an existing timer so you don't create a bazillion timers if you're using it many times in the same component.

var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1];  // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment

Working tree

Your working tree are the files that you are currently working on.

Git index

• The git "index" is where you place files you want commit to the git repository.

• The index is also known as cache, directory cache, current directory cache, staging area, staged files.

• Before you "commit" (checkin) files to the git repository, you need to first place the files in the git "index".

• The index is not the working directory: you can type a command such as git status, and git will tell you what files in your working directory have been added to the git index (for example, by using the git add filename command).

• The index is not the git repository: files in the git index are files that git would commit to the git repository if you used the git commit command.

Shortest

This is size improvement of R. Yaghoobi answer

<input type="number" oninput="this.value|=0"/>

We use here standard shorthand for "OR" operator e.g 9 | 2 = 11 in binary: 0b1001 | 0b1010 = 0b1011 . This operator first cast numbers to integers in implicit way and then do OR. But because OR with zero don't change anything so number is cast to integer. OR with non-number string gives 0.

I've seen a couple cases where this error occurs:

1. using the not equals operator != in a where clause with a list of multiple or values

such as:

where columnName !=('A'||'B')

This can be resolved by using

where columnName not in ('A','B')

2. missing a comparison operator in an if() function:

select if(col1,col1,col2);

in order to select the value in col1 if it exists and otherwise show the value in col2...this throws the error; it can be resolved by using:

select if(col1!='',col1,col2);

Old but still valid question, so heres what I created based on the info provided by others here.

create function fnLastIndexOf(@text varChar(max),@char varchar(1))
returns int
as
begin
return len(@text) - charindex(@char, reverse(@text)) -1
end

if you are working in the java world - intelliJ idea has also extensive xml support, including xsd generation and samle xml from xsd generation, and with plugins you can get xslt debuggers. - especially nice if you plan to use tools such as jaxb afterwards.

You can use \centering with your parbox to do this.

More info here and here.

(Sorry for the Google cached link; the original one I had doesn't work anymore.)

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo implode('~',$array);
?>

and js

$(document).ready( function() {
$('#prev').click(function() {
  $.ajax({
  type: 'POST',
  url: 'ajax.php',
  data: 'id=testdata',
  cache: false,
  success: function(data) {
    result=data.split('~');
    $('#content1').html(result[0]);
  },
  });
});
});

After further reading, and confirmation from Linus G Thiel above, I found I simply had to,

• Downgrade to Node.js 0.6.12
• And either,
  • Install Mocha as global
  • Add ./node_modules/.bin to my PATH

Step 1

In your tsconfig.json

"compileOnSave": true, // change it to true and save the application

if problem is still there then apply step-2

Step 2

Restart your editor

if still problem not resolved then apply step-3

Step 3

Change any route, revert it back and save the application. It'll start compiling. i.e.

const routes: Routes = [
  {
    path: '', // i.e. remove , (comma) and then insert it and save, it'll start compiling
    component: MyComponent
  }
]

Just use window.open() function? The third parameter lets you specify window size.

Example

var strWindowFeatures = "location=yes,height=570,width=520,scrollbars=yes,status=yes";

Bootstrap 2.3 has utility classes text-left, text-right, and text-center, but they do not work in table cells. Until Bootstrap 3.0 is released (where they have fixed the issue) and I am able to make the switch, I have added this to my site CSS that is loaded after bootstrap.css:

.text-right {
    text-align: right !important;
}

.text-center {
    text-align: center !important;
}

.text-left {
    text-align: left !important;
}

We can iterate loop like as C programming.

#!/bin/bash
for ((i=1; i<=20; i=i+1))
do 
      echo $i
done

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

At my previous employer, we used custom HTML tags all the time to hold info about the form elements. The catch: We knew that the user was forced to use IE.

It didn't work well for FireFox at the time. I don't know if FireFox has changed this or not, but be aware that adding your own attributes to HTML elements may or may-not be supported by your reader's browser.

If you can control which browser your reader is using (i.e. an internal web applet for a corporation), then by all means, try it. What can it hurt, right?

1. Allows casts to be found easily in your code using grep or similar tools.
2. Makes it explicit what kind of cast you are doing, and engaging the compiler's help in enforcing it. If you only want to cast away const-ness, then you can use const_cast, which will not allow you to do other types of conversions.
3. Casts are inherently ugly -- you as a programmer are overruling how the compiler would ordinarily treat your code. You are saying to the compiler, "I know better than you." That being the case, it makes sense that performing a cast should be a moderately painful thing to do, and that they should stick out in your code, since they are a likely source of problems.

See Effective C++ Introduction

std::pair already has the required comparison operators, which perform lexicographical comparisons using both elements of each pair. To use this, you just have to provide the comparison operators for types for types K and V.

Also bear in mind that std::sort requires a strict weak ordeing comparison, and <= does not satisfy that. You would need, for example, a less-than comparison < for K and V. With that in place, all you need is

std::vector<pair<K,V>> items; 
std::sort(items.begin(), items.end()); 

If you really need to provide your own comparison function, then you need something along the lines of

template <typename K, typename V>
bool comparePairs(const std::pair<K,V>& lhs, const std::pair<K,V>& rhs)
{
  return lhs.first < rhs.first;
}

Answer to your specific question

Your code was checking all columns within any container, what you need to do is:

• Loop through each container
  • Get the heights of each column within that container
  • Find the highest one
  • Apply that height to every column in that container before moving on to the next one.

Note: Try to provide an example jsfiddle of your issue, it enables us to more easily help you and understand the issue, you get to see the working solution straight away and it encourages quicker responses.

Quick (Rough) Example

$(document).ready(function(){_x000D_
_x000D_
    // Select and loop the container element of the elements you want to equalise_x000D_
    $('.container').each(function(){  _x000D_
      _x000D_
      // Cache the highest_x000D_
      var highestBox = 0;_x000D_
      _x000D_
      // Select and loop the elements you want to equalise_x000D_
      $('.column', this).each(function(){_x000D_
        _x000D_
        // If this box is higher than the cached highest then store it_x000D_
        if($(this).height() > highestBox) {_x000D_
          highestBox = $(this).height(); _x000D_
        }_x000D_
      _x000D_
      });  _x000D_
            _x000D_
      // Set the height of all those children to whichever was highest _x000D_
      $('.column',this).height(highestBox);_x000D_
                    _x000D_
    }); _x000D_
_x000D_
});

.container { border 1px solid red; }_x000D_
.column { border: 1px solid blue; float:left; width: 30%; text-align:center; }

Library!

Here's a library i found that looks promising if you want some more clever equalisation controls

http://brm.io/jquery-match-height-demo/

Addressing @Mem's question

Question: Will $(document).ready() work if you have images that need to load which in turn modify the heights of the containers?

Equalising heights after image load

If you are loading images, you will find that this solution doesn't always work. This is because document.ready is fired at the earliest possible time, which means it does not wait for external resources to be loaded in (such as images).

When your images finally load, they may distort the heights of their containers after the equalisation script has run, causing it too appear not too work.

Solving equalising heights with images

1. Bind to image loading events

This is the best solution (at the time of writing) and involves binding to the img.load event. All you have to do is get a count of how many img's there are $('img').length and then for each load, -1 from that count until you hit zero, then fire the equaliser.

The caveat here is load may not fire in all browsers if the image is in the cache. Look around google/github, there should be a solution script out there. At the time of writing i found waitForImages from Alexander Dickson (untested, this is not an endorsement).

2. Another more reliable solution is the window.load event. This should generally always work. However, if you check the docs out, you'll notice this event fires after ALL external resources are loaded. This means if your images are loaded but there's some javascript waiting to download it won't fire until that completes.

If you load the majority of your externals asyncronously and are clever with minimising, compressing and spreading the load you probably wont have any issues with this method, however a suddenly slow CDN (happens all the time) could cause issues.

In both cases, you could take a dumb approach and apply fallback timers. Have the equalise script run automatically after a set few seconds just in case the event doesn't fire or something is slow out of your control. It's not fool proof, but in reality you'll satisfy 99% of your visitors with this fallback if you tune the timer correctly.

Years later this is still getting upvotes, with flexbox widely supported these days you may want to consider just plain CSS for this, unless there's a specific reason you are using JS for it

.container {_x000D_
  display: flex;_x000D_
  border: 2px dashed red;_x000D_
  margin: 10px 0;_x000D_

}_x000D_
_x000D_
.container.fill-width {_x000D_

  background: green;_x000D_
}

<div class="container">_x000D_
  <div class="column">Some<br>text</div>_x000D_
  <div class="column">Some<br>more<br>text<br>here</div>_x000D_
  <div class="column">One line</div>_x000D_

<div class="container">_x000D_
  <div class="column">Some<br>more<br>even<br>longer<br>text<br>here</div>_x000D_
  <div class="column">Some<br>text</div>_x000D_
  <div class="column">One line</div>_x000D_

<div class="container fill-width">_x000D_
  <div class="column">Some<br>more<br>text<br>here</div>_x000D_

  <div class="column">One line</div>_x000D_
</div>

You can use setScale() e.g.

double d = ...
BigDecimal db = new BigDecimal(d).setScale(12, BigDecimal.ROUND_HALF_UP);

You can use the setspace package which gives you spacing environments, e.g.:

\documentclass{article}
\usepackage{setspace}
\begin{document}
\doublespace
my line of text blah blah blah

new line of text with blank line between
\end{document}

Or use a verbatim environment to control the layout of your code precisely.

I found this very good tutorial on how to install and switch php versions on OSX.

I can switch the version like

$ sphp 7.0 => PHP 7.0
$ sphp 7.3 => PHP 7.3
$ sphp 7.4 => PHP 7.4

Exactly what I want!

Did you import it? Importing matplotlib is not enough.

>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'

but

>>> import matplotlib.pyplot
>>> matplotlib.pyplot

works.

pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.

The most common form of importing pyplot is

import matplotlib.pyplot as plt

Thus, your statements won't be too long, e.g.

plt.plot([1,2,3,4,5])

instead of

matplotlib.pyplot.plot([1,2,3,4,5])

And: pyplot is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

with this code, the id will not appear on the link

    document.querySelectorAll('a[href^="#"]').forEach(anchor => {
        anchor.addEventListener('click', function (e) {
            e.preventDefault();

            document.querySelector(this.getAttribute('href')).scrollIntoView({
                behavior: 'smooth'
            });
        });
    });

In the case you are sure that you should be able to access given class, than this can mean you added several jars to your project containing classes with identical names (or paths) but different content and they are overshadowing each other (typically an old custom build jar contains built-in older version of a 3rd party library).

For example when you add a jar implementing:

a.b.c.d1
a.b.c.d2

but also an older version implementing only:

a.b.c.d1
(d2 is missing altogether or has restricted access)

Everything works fine in the code editor but fails during the compilation if the "old" library overshadows the new one - d2 suddenly turns out "missing or inaccessible" even when it is there.

The solution is a to check the order of compile-time libraries and make sure that the one with correct implementation goes first.

interface: defines the contract for a class which implements it

@interface: defines the contract for an annotation

You could use wmic command:

wmic logicaldisk where drivetype=2 get <DeviceID, VolumeName, Description, ...>

Drivetype 2 indicates that its a removable disk.

Like this:

{% if age > 18 %}
    {% with patient as p %}
    <my html here>
    {% endwith %}
{% else %}
    {% with patient.parent as p %}
    <my html here>
    {% endwith %}
{% endif %}

If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:

p = (age > 18 && patient) or patient.parent

and then just use {{ p }} in the template.

Sorry to reanimate a dead thread, but I have just been dealing with this myself, and after finding all sorts of crazy bloated solutions, I managed to come up with this.

[Long]$actualSize = 0
foreach ($item in (Get-ChildItem $path -recurse | Where {-not $_.PSIsContainer} | ForEach-Object {$_.FullName})) {
   $actualSize += (Get-Item $item).length
}

Quickly and in few lines of code gives me a folder size in Bytes, than can easily be converted to any units you want with / 1MB or the like. Am I missing something? Compared to this overwrought mess it seems rather simple and to the point. Not to mention that code doesn't even work since the called function is not the same name as the defined function. And has been wrong for 6 years. ;) So, any reasons NOT to use this stripped down approach?

From the documentation (help copy-item -full):

-force <SwitchParameter>
    Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.

    Required?                    false
    Position?                    named
    Default value                False
    Accept pipeline input?       false
    Accept wildcard characters?  false

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

Efficient way to iterate your ArrayList followed by this link. This type will improve the performance of looping during iteration

int size = list.size();

}

From my understanding, router.navigate is used to navigate relatively to current path. For eg : If our current path is abc.com/user, we want to navigate to the url : abc.com/user/10 for this scenario we can use router.navigate .

router.navigateByUrl() is used for absolute path navigation.

ie,

If we need to navigate to entirely different route in that case we can use router.navigateByUrl

For example if we need to navigate from abc.com/user to abc.com/assets, in this case we can use router.navigateByUrl()

Syntax :

router.navigateByUrl(' ---- String ----');

router.navigate([], {relativeTo: route})

First, it would be simpler if the onclick handler was set this way:

<a id="someLinkId"href="#">Select</a>
<script type="text/javascript">
  document.getElementById("someLinkId").onClick = 
   function() {
      SelectSurveyItem('<%itemid%>', '<%itemname%>'); return false;
    };

</script>

Then itemid and itemname need to be escaped for JavaScript (that is, " becomes \", etc.).

If you are using Java on the server side, you might take a look at the class StringEscapeUtils from jakarta's common-lang. Otherwise, it should not take too long to write your own 'escapeJavascript' method.

You use the WHERE clause for UPDATE queries. When you INSERT, you are assuming that the row doesn't exist.

The OP's statement would then become;

UPDATE Users SET weight = 160, desiredWeight = 45 where id = 1;

In MySQL, if you want to INSERT or UPDATE, you can use the REPLACE query with a WHERE clause. If the WHERE doesn't exist, it INSERTS, otherwise it UPDATES.

EDIT

I think that Bill Karwin's point is important enough to pull up out of the comments and make it very obvious. Thanks Bill, it has been too long since I have worked with MySQL, I remembered that I had issues with REPLACE, but I forgot what they were. I should have looked it up.

That's not how MySQL's REPLACE works. It does a DELETE (which may be a no-op if the row does not exist), followed by an INSERT. Think of the consequences vis. triggers and foreign key dependencies. Instead, use INSERT...ON DUPLICATE KEY UPDATE.

I tore my hair out over this one too. Your code only works if the user has granted an extended permission for that which is not ideal.

Here's another approach.

In a nutshell, if you turn on the OAuth 2.0 for Canvas advanced option, Facebook will send a $_REQUEST['signed_request'] along with every page requested within your tab app. If you parse that signed_request you can get some info about the user including if they've liked the page or not.

function parsePageSignedRequest() {
    if (isset($_REQUEST['signed_request'])) {
      $encoded_sig = null;
      $payload = null;
      list($encoded_sig, $payload) = explode('.', $_REQUEST['signed_request'], 2);
      $sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
      $data = json_decode(base64_decode(strtr($payload, '-_', '+/'), true));
      return $data;
    }
    return false;
  }
  if($signed_request = parsePageSignedRequest()) {
    if($signed_request->page->liked) {
      echo "This content is for Fans only!";
    } else {
      echo "Please click on the Like button to view this tab!";
    }
  }

There are loads of different design patterns used, but there are a few obvious ones:

• Proxy - used heavily in AOP, and remoting.

• Singleton - beans defined in spring config files are singletons by default.

• Template method - used extensively to deal with boilerplate repeated code (such as closing connections cleanly, etc..). For example JdbcTemplate, JmsTemplate, JpaTemplate.

Update following comments: For MVC, you might want to read the MVC Reference

Some obvious patterns in use in MVC:

• Model View Controller :-) . The advantage with Spring MVC is that your controllers are POJOs as opposed to being servlets. This makes for easier testing of controllers. One thing to note is that the controller is only required to return a logical view name, and the view selection is left to a separate ViewResolver. This makes it easier to reuse controllers for different view technologies.

• Front Controller. Spring provides DispatcherServlet to ensure an incoming request gets dispatched to your controllers.

• View Helper - Spring has a number of custom JSP tags, and velocity macros, to assist in separating code from presentation in views.

For your specific case, the body is for creating a variable, and switching to IEnumerable will force all the operations to be processed on client-side, I propose the following solution.

Obj[] myArray = objects
.Select(o => new
{
    SomeLocalVar = o.someVar, // You can even use any LINQ statement here
    Info = o,
}).Select(o => new Obj()
{
    Var1 = o.SomeLocalVar,
    Var2 = o.Info.var2,
    Var3 = o.SomeLocalVar.SubValue1,
    Var4 = o.SomeLocalVar.SubValue2,
}).ToArray();

Edit: Rename for C# Coding Convention

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

Using numpy, you can define the following:

import numpy as np

def cart2pol(x, y):
    rho = np.sqrt(x**2 + y**2)
    phi = np.arctan2(y, x)
    return(rho, phi)

def pol2cart(rho, phi):
    x = rho * np.cos(phi)
    y = rho * np.sin(phi)
    return(x, y)

here is with one line

try (BufferedReader br = new BufferedReader(
        new InputStreamReader(
           new GZIPInputStream(
              new FileInputStream(
                 "F:/gawiki-20090614-stub-meta-history.xml.gz"))))) 
     {br.readLine();}

In Managed C++, static class syntax is:-

public ref class BitParser abstract sealed
{
    public:
        static bool GetBitAt(...)
        {
            ...
        }
}

... better late than never...

To undo: C-_

To redo after a undo: C-g C-_

Type multiple times on C-_ to redo what have been undone by C-_ To redo an emacs command multiple times, execute your command then type C-xz and then type many times on z key to repeat the command (interesting when you want to execute multiple times a macro)

I am assuming you want to display this as part of the player.

This site breaks down how to get both the current and total time regardless of how you want to display it though using jQuery:

http://dev.opera.com/articles/view/custom-html5-video-player-with-css3-and-jquery/

This will also cover how to set it to a specific div. As philip has already mentioned, .currentTime will give you where you are in the video.

Is something along these lines what you are looking for?

x1 = function(x){
  mu = mean(x)
  l1 = list(s1=table(x),std=sd(x))
  return(list(l1,mu))
}

x1(Fair$age)

Assuming you are talking about the ActionEvent class, then there is a big difference between the two methods.

getActionCommand() gives you a String representing the action command. The value is component specific; for a JButton you have the option to set the value with setActionCommand(String command) but for a JTextField if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField.

getSource() is specified by the EventObject class that ActionEvent is a child of (via java.awt.AWTEvent). This gives you a reference to the object that the event came from.

Edit:

Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.

public class Events implements ActionListener {

  private static JFrame frame; 

  public static void main(String[] args) {

    frame = new JFrame("JTextField events");
    frame.getContentPane().setLayout(new FlowLayout());

    JTextField field1 = new JTextField(10);
    field1.addActionListener(new Events());
    frame.getContentPane().add(new JLabel("Field with no action command set"));
    frame.getContentPane().add(field1);

    JTextField field2 = new JTextField(10);
    field2.addActionListener(new Events());
    field2.setActionCommand("my action command");
    frame.getContentPane().add(new JLabel("Field with an action command set"));
    frame.getContentPane().add(field2);


    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(220, 150);
    frame.setResizable(false);
    frame.setVisible(true);
  }

  @Override
  public void actionPerformed(ActionEvent evt) {
    String cmd = evt.getActionCommand();
    JOptionPane.showMessageDialog(frame, "Command: " + cmd);
  }

}

Here's what is (IMO) by far the best solution in one line, per modern javascript standards:

const str1 = 'abc';
const str2 = 'abc';
return (str1 === str2); // true


const str1 = 'abcd';
const str2 = 'abc';
return (str1 === str2); // false

const str1 = 'abc';
const str2 = 'abcd';
return (str1 === str2); // false

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

this is the most simple way but it works for me with a ComboBox1 name

SOLUTION on 3 Basic STEPS:

step 1.

Declare a variable at the beginning of your form which will hold the original text value of the ComboBox. Example:

     Dim xCurrentTextValue as string

step 2.

Create the event combobox1 key down and Assign to xCurrentTextValue variable the current text of the combobox if any key diferrent than "ENTER" is pressed the combobox text value keeps the original text value

Example:

Private Sub ComboBox1_KeyDown(sender As Object, e As KeyEventArgs) Handles ComboBox1.KeyDown

    xCurrentTextValue = ComboBox1.Text

    If e.KeyCode <> Keys.Enter Then
        Me.ComboBox1.Text = xCmbItem
    End If

End Sub

step 3.

Validate the when the combo text is changed if len(xcurrenttextvalue)> 0 or is different than nothing then the combobox1 takes the xcurrenttextvalue variable value

Private Sub ComboBox1_TextChanged(sender As Object, e As EventArgs) Handles ComboBox1.TextChanged
    If Len(xCurrentTextValue) > 0 Then
        Me.ComboBox1.Text = xCurrentTextValue

    End If
End Sub

========================================================== that's it,

Originally I only tried the step number 2, but I have problems when you press the DEL key and DOWN arrow key, also for some reason it didn't validate the keydown event unless I display any message box

!Sorry, this is a correction on step number 2, I forgot to change the variable xCmbItem to xCurrentTextValue, xCmbItem it was used for my personal use

THIS IS THE CORRECT CODE

xCurrentTextValue = ComboBox1.Text

If e.KeyCode <> Keys.Enter Then
    Me.ComboBox1.Text = xCurrentTextValue
End If

Thanks for replies.

I did like this:

puts 'find' if array.include?(value)

There was a time when adding strings into an array and finalising the string by using join was the fastest/best method. These days browsers have highly optimised string routines and it is recommended that + and += methods are fastest/best

Have a look at the example in this link :

http://docs.angularjs.org/api/ngSanitize.$sanitize

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

Basically, all you have to do is

select ..., (select ... from ... where ...) as ..., ..., from ... where ...

For exemple. You can insert the (select ... from ... where) wherever you want it will be replaced by the corresponding data.

I know that the others exemple (even if each of them are really great :) ) are a bit complicated to understand for the newbies (like me :p) so i hope this "simple" exemple will help some of you guys :)

Well, I totally agree with answers already exist on this point:

• bootstrap.yml is used to save parameters that point out where the remote configuration is and Bootstrap Application Context is created with these remote configuration.

Actually, it is also able to store normal properties just the same as what application.yml do. But pay attention on this tricky thing:

• If you do place properties in bootstrap.yml, they will get lower precedence than almost any other property sources, including application.yml. As described here.

Let's make it clear, there are two kinds of properties related to bootstrap.yml:

• Properties that are loaded during the bootstrap phase. We use bootstrap.yml to find the properties holder (A file system, git repository or something else), and the properties we get in this way are with high precedence, so they cannot be overridden by local configuration. As described here.
• Properties that are in the bootstrap.yml. As explained early, they will get lower precedence. Use them to set defaults maybe a good idea.

So the differences between putting a property on application.yml or bootstrap.yml in spring boot are:

• Properties for loading configuration files in bootstrap phase can only be placed in bootstrap.yml.
• As for all other kinds of properties, place them in application.yml will get higher precedence.

SizedBox(
    width: 200.0,
    child: Text('PRODUCERS CAVITY FIGHTER 50X140g',
                overflow: TextOverflow.ellipsis,
                style: Theme.of(context).textTheme.body2))

Just wrap in inside a widget that can take a specific width for it to work or it will assume the width of the parent container.

Try using the following code snippet. This should solve your issue.

body, html { 
    overflow-x: hidden; 
    overflow-y: auto;
}

I ran into this error in a different situation, posting the resolution for those arriving via search: from within Visual Studio, I had copied a file from one project and pasted into another. Turns out that creates a symbolic link, not an actual copy. Thus the project did not find the file in the current working directory as expected. When I made a physical copy instead, in Windows Explorer, suddenly #include "myfile.h" worked.

A lot of people mention companion objects, which is correct. But, just so you know, you can also use any sort of object (using the object keyword, not class) i.e.,

object StringUtils {
    fun toUpper(s: String) : String { ... }
}

Use it just like any static method in java:

StringUtils.toUpper("foobar")

That sort of pattern is kind of useless in Kotlin though, one of its strengths is that it gets rid of the need for classes filled with static methods. It is more appropriate to utilize global, extension and/or local functions instead, depending on your use case. Where I work we often define global extension functions in a separate, flat file with the naming convention: [className]Extensions.kt i.e., FooExtensions.kt. But more typically we write functions where they are needed inside their operating class or object.

This beautiful code here creates a table with each td having array values. Not my code, but it helped me!

var rows = 6, cols = 7;

for(var i = 0; i < rows; i++) {
  $('table').append('<tr></tr>');
  for(var j = 0; j < cols; j++) {
    $('table').find('tr').eq(i).append('<td></td>');
    $('table').find('tr').eq(i).find('td').eq(j).attr('data-row', i).attr('data-col', j);
  }
}

This should do what you want:

C:\PS> if ('=keep this,' -match '=([^,]*)') { $matches[1] }
keep this

Check your monitor scaling.

My problem turned out to be this:

It turned out to be different DPI-scaling on the primary and secondary monitor. When the secondary monitor was set to 125% (same as the primary monitor) the icons appeared again.

SQL Server can implicitly cast strings in the form of 'YYYYMMDD' to a datetime - all other strings must be explicitly cast. here are two quick code blocks which will do the conversion from the form you are talking about:

version 1 uses unit variables:

BEGIN 
DECLARE @input VARCHAR(8), @mon CHAR(2), 
@day char(2), @year char(4), @output DATETIME

SET @input = '10022009'   --today's date


SELECT @mon = LEFT(@input, 2), @day = SUBSTRING(@input, 3,2), @year = RIGHT(@input,4)

SELECT @output = @year+@mon+@day 
SELECT @output 
END

version 2 does not use unit variables:

BEGIN 
DECLARE @input CHAR(8), @output DATETIME
SET @input = '10022009' --today's date 

SELECT @output = RIGHT(@input,4) + SUBSTRING(@input, 3,2) + LEFT(@input, 2)

SELECT @output
END

Both cases rely on sql server's ability to do that implicit conversion.
