I went into wp-config/ and deleted the object-cache.php and advanced-cache.php and it worked fine for me.

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.

After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

Simply use FIND_IN_SET like that:

mysql> SELECT FIND_IN_SET('b','a,b,c,d');
        -> 2

so you can do:

select * from Fruits where FIND_IN_SET(fruit, fruitArray) > 0

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

As already mentioned by Mike, there is no option 'Enable NuGet Package Restore' in VS2015. You'll have to invoke the restore process manually. A nice way - without messing with files and directories - is using the NuGet Package Management Console: Click into the 'Quick start' field (usually in the upper right corner), enter console, open the management console, and enter command:

Update-Package –reinstall

This will re-install all packages of all projects in your solution. To specify a single project, enter:

Update-Package –reinstall -ProjectName MyProject

Of course this is only necessary when the Restore button - sometimes offered by VS2015 - is not available. More useful update commands are listed and explained here: https://docs.microsoft.com/en-us/nuget/consume-packages/reinstalling-and-updating-packages

The problem is

When a Scanner is closed, it will close its input source if the source implements the Closeable interface.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

Thus scan.close() closes System.in.

To fix it you can make

Scanner scan static and do not close it in PromptCustomerQty. Code below works.

public static void main (String[] args) {   

// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");

// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); 
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);

// Define internal variables 
// ## DONT CHANGE 
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output

// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);

// Ask users for quantities 
PromptCustomerQty(customer, ProductList);

// Ask user for payment method
PromptCustomerPayment(customer);

// Create the header
PrintHeader(customer, formatString);

// Create Body
PrintBody(ProductList, formatString);   
}

static Scanner scan;

public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList)               {
// Initiate a Scanner
scan = new Scanner(System.in);

// **** VARIABLES ****
int qty = 0;

// Greet Customer
System.out.println("Hello " + customer.getName());

// Loop through each item and ask for qty desired
for (Product p : ProductList) {

    do {
    // Ask user for qty
    System.out.println("How many would you like for product: " + p.name);
    System.out.print("> ");

    // Get input and set qty for the object
    qty = scan.nextInt();

    }
    while (qty < 0); // Validation

    p.setQty(qty); // Set qty for object
    qty = 0; // Reset count
}

// Cleanup

}

public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";

// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");

payment = scan.next();

} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));

// Check/set result
if (payment.toLowerCase() == "yes") {
    customer.setPaidInFull(true);
}
else {
    customer.setPaidInFull(false);
}
}

On a side note, you shouldn't use == for String comparision, use .equals instead.

For now, use an EditText. Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString())).

In the future, you might consider a NumberPicker widget, once that becomes available (slated to be in Honeycomb).

Try innerText property:

var content = document.getElementById("one").innerText;
alert(content);

Use subprocess.check_output (new in python 2.7). It will suppress stdout and raise an exception if the command fails. (It actually returns the contents of stdout, so you can use that later in your program if you want.) Example:

import subprocess
try:
    subprocess.check_output(['espeak', text])
except subprocess.CalledProcessError:
    # Do something

You can also suppress stderr with:

    subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT)

For earlier than 2.7, use

import os
import subprocess
with open(os.devnull, 'w')  as FNULL:
    try:
        subprocess._check_call(['espeak', text], stdout=FNULL)
    except subprocess.CalledProcessError:
        # Do something

Here, you can suppress stderr with

        subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL)

Actually, this may or may not be much help but you could write a script which created a Java class for each Python class, including method stubs, placing the Python implementation of the method inside the Javadoc

In fact, this is probably pretty easy to knock up in Python.

I worked for a company which undertook a port to Java of a huge Smalltalk (similar-ish to Python) system and this is exactly what they did. Filling in the methods was manual but invaluable, because it got you to really think about what was going on. I doubt that a brute-force method would result in nice code.

Here's another possibility: can you convert your Python to Jython more easily? Jython is just Python for the JVM. It may be possible to use a Java decompiler (e.g. JAD) to then convert the bytecode back into Java code (or you may just wish to run on a JVM). I'm not sure about this however, perhaps someone else would have a better idea.

Java is a compiled programming language, but rather than compile straight to executable machine code, it compiles to an intermediate binary form called JVM byte code. The byte code is then compiled and/or interpreted to run the program.

Agree it is probably due to a problem in resources that is preventing build of R.Java in gen. In my case a cut n paste had given a duplicate app name in string. Sort the fault, delete gen directory and clean.

Swift 3.0

Create a ViewController with the UITableViewDelegate and UITableViewDataSource protocols. Then create a tableView inside it, declaring its style to be UITableViewStyle.grouped. This will fix the headers.

lazy var tableView: UITableView = {
    let view = UITableView(frame: UIScreen.main.bounds, style: UITableViewStyle.grouped)
    view.delegate = self
    view.dataSource = self
    view.separatorStyle = .none
    return view
}()

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

here is the correct way of using proxy along with creds..

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);

IWebProxy proxy = request.Proxy;                    
if (proxy != null)
{
    Console.WriteLine("Proxy: {0}", proxy.GetProxy(request.RequestUri));
}
else
{
    Console.WriteLine("Proxy is null; no proxy will be used");
}

WebProxy myProxy = new WebProxy();
Uri newUri = new Uri("http://20.154.23.100:8888");
// Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
myProxy.Address = newUri;
// Create a NetworkCredential object and associate it with the 
// Proxy property of request object.
myProxy.Credentials = new NetworkCredential("userName", "password");
request.Proxy = myProxy;

Thanks everyone for help... :)

I just needed to make artisan executable.

chmod +x artisan

...and it works without the php prefix then.

I'm guessing the question you really care about here is:

Is there a way to force Python to release all the memory that was used (if you know you won't be using that much memory again)?

No, there is not. But there is an easy workaround: child processes.

If you need 500MB of temporary storage for 5 minutes, but after that you need to run for another 2 hours and won't touch that much memory ever again, spawn a child process to do the memory-intensive work. When the child process goes away, the memory gets released.

This isn't completely trivial and free, but it's pretty easy and cheap, which is usually good enough for the trade to be worthwhile.

First, the easiest way to create a child process is with concurrent.futures (or, for 3.1 and earlier, the futures backport on PyPI):

with concurrent.futures.ProcessPoolExecutor(max_workers=1) as executor:
    result = executor.submit(func, *args, **kwargs).result()

If you need a little more control, use the multiprocessing module.

The costs are:

• Process startup is kind of slow on some platforms, notably Windows. We're talking milliseconds here, not minutes, and if you're spinning up one child to do 300 seconds' worth of work, you won't even notice it. But it's not free.
• If the large amount of temporary memory you use really is large, doing this can cause your main program to get swapped out. Of course you're saving time in the long run, because that if that memory hung around forever it would have to lead to swapping at some point. But this can turn gradual slowness into very noticeable all-at-once (and early) delays in some use cases.
• Sending large amounts of data between processes can be slow. Again, if you're talking about sending over 2K of arguments and getting back 64K of results, you won't even notice it, but if you're sending and receiving large amounts of data, you'll want to use some other mechanism (a file, mmapped or otherwise; the shared-memory APIs in multiprocessing; etc.).
• Sending large amounts of data between processes means the data have to be pickleable (or, if you stick them in a file or shared memory, struct-able or ideally ctypes-able).

Easy way to get the text inside of the editor or the length of it :)

 var editorText = CKEDITOR.instances['<%= your_editor.ClientID %>'].getData();
 alert(editorText);

 var editorTextLength = CKEDITOR.instances['<%= your_editor.ClientID %>'].getData().length;
 alert(editorTextLength);

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

You can install from nuget as the the below image:

Or, run the below command line on Package Manager Console:

Install-Package Microsoft.AspNet.WebApi

The hash-variant has one pitfall: On the command line you can for example type in

one_folder/process

to have process executed. For this the parent folder of one_folder must be in $PATH. But when you try to hash this command, it will always succeed:

hash one_folder/process; echo $? # will always output '0'

I add credentials for HttpWebRequest.

myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

Math.floor(n)

where n is a double. This'll actually return a double, it seems, so make sure that you typecast it after.

The former is fastest. Turns out that val is immutable, and so a new string object is created with String.ToLowerCase(), rather than just direct comparison with the string comparer. Creating a new string object can be costly if you're doing this many times a second.

I had a test project that references 2 other projects that each referenced different versions (in different locations) of the same dll. This confused the compiler.

SWIFT4 - Easy and elegant way of decoding JSON strings to Struct.

First step - encode String to Data with .utf8 encoding.

Than decode your Data to YourDataStruct.

struct YourDataStruct: Codable {

let type, id: String

init(_ json: String, using encoding: String.Encoding = .utf8) throws {
    guard let data = json.data(using: encoding) else {
        throw NSError(domain: "JSONDecoding", code: 0, userInfo: nil)
    }
    try self.init(data: data)
}

init(data: Data) throws {
    self = try JSONDecoder().decode(YourDataStruct.self, from: data)
}                                                                      
}

do { let successResponse = try WSDeleteDialogsResponse(response) }
} catch {}

Try this,

1.Rename your index.html to “main.html”

2.Create a new “index.html” and put the following content into it:

<!doctype html>
<html>
  <head>
   <title>tittle</title>
   <script>
     window.location='./main.html';
   </script>
  <body>
  </body>
</html>

3.Rebuild your app! No more errors!

for i in range(3):
    print(i)

    if i == 2:
        print("Too big - I'm giving up!")
        break;
else:
    print("Completed successfully")

"else" here is crazily simple, just mean

1, "if for clause is completed"

for i in range(3):
    print(i)

    if i == 2:
        print("Too big - I'm giving up!")
        break;
if "for clause is completed":
    print("Completed successfully")

It's wielding to write such long statements as "for clause is completed", so they introduce "else".

else here is a if in its nature.

2, However, How about for clause is not run at all

In [331]: for i in range(0):
     ...:     print(i)
     ...: 
     ...:     if i == 9:
     ...:         print("Too big - I'm giving up!")
     ...:         break
     ...: else:
     ...:     print("Completed successfully")
     ...:     
Completed successfully

So it's completely statement is logic combination:

if "for clause is completed" or "not run at all":
     do else stuff

or put it this way:

if "for clause is not partially run":
    do else stuff

or this way:

if "for clause not encounter a break":
    do else stuff

There are 2 Reasons why we have to Normalize Input Features before Feeding them to Neural Network:

Reason 1: If a Feature in the Dataset is big in scale compared to others then this big scaled feature becomes dominating and as a result of that, Predictions of the Neural Network will not be Accurate.

Example: In case of Employee Data, if we consider Age and Salary, Age will be a Two Digit Number while Salary can be 7 or 8 Digit (1 Million, etc..). In that Case, Salary will Dominate the Prediction of the Neural Network. But if we Normalize those Features, Values of both the Features will lie in the Range from (0 to 1).

Reason 2: Front Propagation of Neural Networks involves the Dot Product of Weights with Input Features. So, if the Values are very high (for Image and Non-Image Data), Calculation of Output takes a lot of Computation Time as well as Memory. Same is the case during Back Propagation. Consequently, Model Converges slowly, if the Inputs are not Normalized.

Example: If we perform Image Classification, Size of Image will be very huge, as the Value of each Pixel ranges from 0 to 255. Normalization in this case is very important.

Mentioned below are the instances where Normalization is very important:

1. K-Means
2. K-Nearest-Neighbours
3. Principal Component Analysis (PCA)
4. Gradient Descent

Just quote the argument to echo:

( IFS=$'\n'; echo "${my_array[*]}" )

The old freegeoip API is now deprecated and will be discontinued on July 1st, 2018.

The new API is from https://ipstack.com. You have to create the account in ipstack.Then you can use the access key in the API url.

$url = "http://api.ipstack.com/122.167.180.20?access_key=ACCESS_KEY&format=1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response = json_decode($response);
$city  = $response->city; //You can get all the details like longitude,latitude from the $response .

[UPDATE] As of ~June 2017, Docker for Mac takes care of all the annoying parts of this where you have to mess with VirtualBox. It lets you map basically everything on your local host using the /private prefix. More info here. [/UPDATE]

All the current answers talk about Boot2docker. Since that's now deprecated in favor of docker-machine, this works for docker-machine:

First, ssh into the docker-machine vm and create the folder we'll be mapping to:

docker-machine ssh $MACHINE_NAME "sudo mkdir -p \"$VOL_DIR\""

Now share the folder to VirtualBox:

WORKDIR=$(basename "$VOL_DIR")
vboxmanage sharedfolder add "$MACHINE_NAME" --name "$WORKDIR" --hostpath "$VOL_DIR" --transient

Finally, ssh into the docker-machine again and mount the folder we just shared:

docker-machine ssh $MACHINE_NAME "sudo mount -t vboxsf -o uid=\"$U\",gid=\"$G\" \"$WORKDIR\" \"$VOL_DIR\""

Note: for UID and GID you can basically use whatever integers as long as they're not already taken.

This is tested as of docker-machine 0.4.1 and docker 1.8.3 on OS X El Capitan.

You should define an interface in your fragment class and implement that interface in its parent activity. The details are outlined here http://developer.android.com/guide/components/fragments.html#EventCallbacks . The code would look similar to:

Fragment:

public static class FragmentA extends DialogFragment {

    OnArticleSelectedListener mListener;

    // Container Activity must implement this interface
    public interface OnArticleSelectedListener {
        public void onArticleSelected(Uri articleUri);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            mListener = (OnArticleSelectedListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString() + " must implement OnArticleSelectedListener");
        }
    }
}

Activity:

public class MyActivity extends Activity implements OnArticleSelectedListener{

    ...
    @Override
    public void onArticleSelected(Uri articleUri){

    }
    ...
}

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

I just put --password flag into my command and after hitting Enter it asked me for password, which I supplied.

In [1]: x = "anmxcjkwnekmjkldm!^%@(*)#_+@78935014712jksdfs"

Now, For positive index ranges for x is from 0 to 44 (i.e. length - 1)

In [3]: x[0]
Out[3]: 'a'
In [4]: x[45]
---------------------------------------------------------------------------

Out[5]: 's'

For Negative index, index ranges from -1 to -45

In [6]: x[-1]
Out[6]: 's'
In [7]: x[-45]
Out[7]: 'a

For negative index, negative [length -1] i.e. the last valid value of positive index will give second list element as the list is read in reverse order,

Out[8]: 'n'

Other, index's examples,

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!

This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.

mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.

    // Load modules
const PoolManager = require('mysql-connection-pool-manager');

// Options
const options = {
  ...example settings
}

// Initialising the instance
const mySQL = PoolManager(options);

// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

// Initialising connection
connection.connect();

// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

// Ending connection
connection.end();

It's a way of taking small operation and putting it very close to where it is used (not unlike declaring a variable close to its use point). This is supposed to make your code more readable. By anonymizing the expression, you're also making it a lot harder for someone to break your client code if it the function is used somewhere else and modified to "enhance" it.

Similarly, why do you need to use foreach? You can do everything in foreach with a plain for loop or just using IEnumerable directly. Answer: you don't need it but it makes your code more readable.

It may not be the most common git server setup, but having played with different layouts, tools, mirroring and permission schemes, I'd say one pretty solid alternative for enterprise repositories is Gerrit, which may seem surprising as it is more known as a code review tool. We started using it as code review and it slowly became our main repository, deprecating g3/gitolite

• It is straightforward to deploy (you basically drop the .war in a tomcat)
• has a web ui to manage repositories, groups and permissions (or a ssh cli)
• has a built-in java ssh and git implementation, so you have nothing else to set up
• ldap support for users and groups (usually a must for companies)
• a very flexible permission system (with project groups, permission inheritance, restricting read/write/branching/unreviewed writes/etc)
• code review capabilities (if you're into that thing)
• repo mirroring (to push some repositories to github or other public repo)

In addition, it's used by large projects (e.g. android, chrome) so it does scales and is now fairly solid. Just give your users the PUSH permission if you want to allow bypassing the code review part.

FORMAT() is slower than CONVERT(). This answer is slightly better than @jpx's answer because it only does a replace on the time part of the date.

112 = yyyymmdd - no format change needed

108 = hh:mm:ss - remove :

SELECT CONVERT(VARCHAR, GETDATE(), 112) + 
       REPLACE(CONVERT(VARCHAR, GETDATE(), 108), ':', '')

//increase char array size if u want take more no. of characters.

#include <stdio.h>
int main()
{
    char s[10],s1[10];
    scanf("\n");//imp for below statement to work
    scanf("%[^\n]%c",s);//to take input till the you click enter
    scanf("%s",s1);//to take input till a space
    printf("%s",s);
    printf("%s",s1);
    return 0;
}

try casting the value

double d = 1.2345;
long l = (long) d;

I would try to unzip and untar separately and see what happens:

mv Doctrine-1.2.0.tgz Doctrine-1.2.0.tar.gz
gunzip Doctrine-1.2.0.tar.gz
tar xf Doctrine-1.2.0.tar

It can also be done using backtracking by maintaining a visited array.

void foo(vector<vector<int> > &s,vector<int> &data,int go,int k,vector<int> &vis,int tot)
{

    vis[go]=1;
    data.push_back(go);
    if(data.size()==k)
    {
        s.push_back(data);
        vis[go]=0;
    data.pop_back();
        return;
    }

    for(int i=go+1;i<=tot;++i)
    {
       if(!vis[i])
       {
           foo(s,data,i,k,vis,tot);
       }
    }
    vis[go]=0;
    data.pop_back();
}


vector<vector<int> > Solution::combine(int n, int k) {
   vector<int> data;
   vector<int> vis(n+1,0);
   vector<vector<int> > sol;
   for(int i=1;i<=n;++i)
   {
       for(int i=1;i<=n;++i) vis[i]=0;
   foo(sol,data,i,k,vis,n);
   }
   return sol;

}

This is how you save the relevant file as a Excel12 (.xlsx) file... It is not as you would intuitively think i.e. using Excel.XlFileFormat.xlExcel12 but Excel.XlFileFormat.xlOpenXMLWorkbook. The actual C# command was

excelWorkbook.SaveAs(strFullFilePathNoExt, Excel.XlFileFormat.xlOpenXMLWorkbook, Missing.Value,
    Missing.Value, false, false, Excel.XlSaveAsAccessMode.xlNoChange, 
    Excel.XlSaveConflictResolution.xlUserResolution, true, 
    Missing.Value, Missing.Value, Missing.Value);

I hope this helps someone else in the future.

Missing.Value is found in the System.Reflection namespace.

This works on SQL Server 2000.

use master
select count(*) From sysxlogins WHERE NAME = 'myUsername'

on SQL 2005, change the 2nd line to

select count(*) From syslogins WHERE NAME = 'myUsername'

I'm not sure about SQL 2008, but I'm guessing that it will be the same as SQL 2005 and if not, this should give you an idea of where t start looking.

if you are using gridview then you can show only the time with DataFormatString="{0:t}" example:

    By bind the value:-
<asp:Label ID="lblreg" runat="server" Text='<%#Eval("Registration_Time ", "{0:t}") %>'></asp:Label>

By bound filed:-
<asp:BoundField DataField=" Registration_Time" HeaderText="Brithday" SortExpression=" Registration Time " DataFormatString="{0:t}"/>

You can use try-catch block to check for integer value

for eg:

User inputs in form of string

try
{
   int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
  //If number is not integer,you wil get exception and exception message will be printed
  System.out.println(e.getMessage());
}

For what it worth, if anyone has this problem only in VSCode, just restart VSCode and it should fix it. Sometimes, Intellisense seems to mess up with imports or types.

Referencing assemblies that are not used during build is not the correct practice. You should augment your build file so it will copy the additional files. Either by using a post build event or by updating the property group.

Some examples can be found in other post

• MSBuild to copy dynamically generated files as part of project dependency
• VS2010 How to include files in project, to copy them to build output directory automatically during build or publish

This question is asked every day in some variation. The answer is: keep your data out of your variable names, and this is the obligatory blog post.

In this case, why not make a list of objs?

objs = [MyClass() for i in range(10)]
for obj in objs:
    other_object.add(obj)

objs[0].do_sth()

Just tell composer to use source if available:

composer update --prefer-source

Or:

composer install --prefer-source

Then you will get packages as cloned repositories instead of extracted tarballs, so you can make some changes and commit them back. Of course, assuming you have write/push permissions to the repository and Composer knows about project's repository.

Disclaimer: I think I may answered a little bit different question, but this was what I was looking for when I found this question, so I hope it will be useful to others as well.

If Composer does not know, where the project's repository is, or the project does not have proper composer.json, situation is a bit more complicated, but others answered such scenarios already.

I found this brilliant solution here, it uses the simple logic NAN!=NAN. https://www.codespeedy.com/check-if-a-given-string-is-nan-in-python/

Using above example you can simply do the following. This should work on different type of objects as it simply utilize the fact that NAN is not equal to NAN.

 import numpy as np
 s = pd.Series(['apple', np.nan, 'banana'])
 s.apply(lambda x: x!=x)
 out[252]
 0    False
 1     True
 2    False
 dtype: bool

For those using AngularJS and Angular UI Router with this, here is my solution (using mollwe's toggle). Where ".navbar-main-collapse" is my "data-target".

Create directive:

module.directive('navbarMainCollapse', ['$rootScope', function ($rootScope) {
    return {
        restrict: 'C',
        link: function (scope, element) {
            //watch for state/route change (Angular UI Router specific)
            $rootScope.$on('$stateChangeSuccess', function () {
                if (!element.hasClass('collapse')) {
                    element.collapse('hide');
                }
            });
        }
    };
}]);

Use Directive:

<div class="collapse navbar-collapse navbar-main-collapse">
    <your menu>

Try this.

if(is_array($value) || is_object($value)){
    foreach($value as $item){
     //somecode
    }
}

Try using the ASCII code for those values:

^([a-zA-Z0-9 .\x26\x27-]+)$

• \x26 = &
• \x27 = '

The format is \xnn where nn is the two-digit hexadecimal character code. You could also use \unnnn to specify a four-digit hex character code for the Unicode character.

local_action runs the command on the local server, not on the servers you specify in hosts parameter.

Change your "Execute the script" task to

- name: Execute the script
  command: sh /home/test_user/test.sh

and it should do it.

You don't need to repeat sudo in the command line because you have defined it already in the playbook.

According to Ansible Intro to Playbooks user parameter was renamed to remote_user in Ansible 1.4 so you should change it, too

remote_user: test_user

So, the playbook will become:

---
- name: Transfer and execute a script.
  hosts: server
  remote_user: test_user
  sudo: yes
  tasks:
     - name: Transfer the script
       copy: src=test.sh dest=/home/test_user mode=0777

     - name: Execute the script
       command: sh /home/test_user/test.sh

select t2.* 
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar)  + '%/more' 
where t1.id > 9000

Using concat like suggested is even better though

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?php 
function compress($source, $destination, $quality) {

    $info = getimagesize($source);

    if ($info['mime'] == 'image/jpeg') 
        $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
        $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
        $image = imagecreatefrompng($source);

    imagejpeg($image, $destination, $quality);

    return $destination;
}

$source_img = 'source.jpg';
$destination_img = 'destination .jpg';

$d = compress($source_img, $destination_img, 90);
?>

$d = compress($source_img, $destination_img, 90);

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source);

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

If you having a common class that is applied to many elements you can create a custom directive that will add that class like ng-show/ng-hide.

This directive will add the class 'active' to the button if it's clicked

module.directive('ngActive',  ['$animate', function($animate) {
  return function(scope, element, attr) {
    scope.$watch(attr.ngActive, function ngActiveWatchAction(value){
      $animate[value ? 'addClass' : 'removeClass'](element, 'active');
    });
  };
}]);

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.

To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY

which evals to this:

package main

import "fmt"

type Blah struct {
    babyKitten int
    kittenSays *string
}

func main() {
    meow := "meow"
    Blahs := []Blah{}
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{2, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    //fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
    Blahs = nil
    meow2 := "nyan"
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow2})
    fmt.Printf("Blahs: %v\n", Blahs)
    fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}

Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan

which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan

I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:

[]MyStruct = nil

Placing @Transient on getter with private field worked for me.

private String name;

    @Transient
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

You want to use css float for this, you can put it directly in your code.

<body>
<img src="website_art.png" height= "75" width="235" style="float:left;"/>
<h3 style="float:right;">The Art of Gaming</h3>
</body>

But I would really suggest learning the basics of css and splitting all your styling out to a separate style sheet, and use classes. It will help you in the future. A good place to start is w3schools or, perhaps later down the path, Mozzila Dev. Network (MDN).

HTML:

<body>
  <img src="website_art.png" class="myImage"/>
  <h3 class="heading">The Art of Gaming</h3>
</body>

CSS:

.myImage {
  float: left;
  height: 75px;
  width: 235px;
  font-family: Veranda;
}
.heading {
  float:right;
}

I am assuming you mean using XSD files. Surprisingly there aren't many python XML libraries that support this. lxml does however. Check Validation with lxml. The page also lists how to use lxml to validate with other schema types.

The ToolTip is a single WinForms control that handles displaying tool tips for multiple elements on a single form.

Say your button is called MyButton.

1. Add a ToolTip control (under Common Controls in the Windows Forms toolbox) to your form.
2. Give it a name - say MyToolTip
3. Set the "Tooltip on MyToolTip" property of MyButton (under Misc in the button property grid) to the text that should appear when you hover over it.

The tooltip will automatically appear when the cursor hovers over the button, but if you need to display it programmatically, call

MyToolTip.Show("Tooltip text goes here", MyButton);

in your code to show the tooltip, and

MyToolTip.Hide(MyButton);

to make it disappear again.

It's not an array.

var json = {"cool":"34.33","alsocool":"45454"};
json.coolness = 34.33;

or

var json = {"cool":"34.33","alsocool":"45454"};
json['coolness'] = 34.33;

you could do it as an array, but it would be a different syntax (and this is almost certainly not what you want)

var json = [{"cool":"34.33"},{"alsocool":"45454"}];
json.push({"coolness":"34.33"});

Note that this variable name is highly misleading, as there is no JSON here. I would name it something else.

No need to add extra elements. While flexbox uses very non-intuitive property names if you know what it can do you'll find yourself using it quite often.

<div style="display: flex; justify-content: space-between;">
<span>Item Left</span>
<span>Item Right</span>
</div>

Plan on needing this often?

.align_between {display: flex; justify-content: space-between;}

I see other people using secondary words in the primary position which makes a mess of information hierarchy. If align is the primary task and right, left, and/or between are the secondary the class should be .align_outer, not .outer_align as it will make sense as you vertically scan your code:

.align_between {}
.align_left {}
.align_outer {}
.align_right {}

Good habits over time will allow you to get to bed sooner than later.

Definitely a late answer to this question. One possibility is to use the ListIterator in a for loop. It's not as clean as colon-syntax, but it works.

List<String> exampleList = new ArrayList<>();
exampleList.add("One");
exampleList.add("Two");
exampleList.add("Three");

//Forward iteration
for (String currentString : exampleList) {
    System.out.println(currentString); 
}

//Reverse iteration
for (ListIterator<String> itr = exampleList.listIterator(exampleList.size()); itr.hasPrevious(); /*no-op*/ ) {
    String currentString = itr.previous();
    System.out.println(currentString); 
}

Credit for the ListIterator syntax goes to "Ways to iterate over a list in Java"

PrjForm was set to ".Net Framework 4 Client Profile" I changed it to ".Net Framework 4", and now I have a successful build.

This worked for me too. Thanks a lot. I was trying an RDF example for dotNet where in I downloaded kit from dotnetrdf.

NET4 Client Profile: Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework: Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes: If you are building Server apps, Such as:

• ASP.Net apps
• Server-side ASMX based web services

If you use legacy client scenarios, Such as: o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.

• Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)

If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)
        .where(predicateResult);

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)
        .getResultList();  

For Fedora >= 25 and python >= 3, we might need to include the dependencies for Tkinter

sudo dnf install python3-tkinter

You can do :

df['industry'] = 'yyy'

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

This basic function handles swapping array keys and keeping the array in the original order...

public function keySwap(array $resource, array $keys)
{
    $newResource = [];

    foreach($resource as $k => $r){
        if(array_key_exists($k,$keys)){
            $newResource[$keys[$k]] = $r;
        }else{
            $newResource[$k] = $r;
        }
    }

    return $newResource;
}

You could then loop through and swap all 'a' keys with 'z' for example...

$inputs = [
  0 => ['a'=>'1','b'=>'2'],
  1 => ['a'=>'3','b'=>'4']
]

$keySwap = ['a'=>'z'];

foreach($inputs as $k=>$i){
    $inputs[$k] = $this->keySwap($i,$keySwap);
}

You will need to configure your Win7 PC as a Time Server, and then configure the RasPi to connect to it for NTP services.

Configure Win7 as authoritative time server. Configure RasPi time server lookup.

You can check for NaN by using var != var. NaN does not equal NaN.

EDIT: This is probably by far the worst method. It's confusing, terrible for readability, and overall bad practice.

String word = "blah blah";

for(int i =0;i<word.length;++i)
{

if(Character.isLowerCase(word.charAt(i)){
System.out.print((int)word.charAt(i) - (int)'a'+1);
}
else{
System.out.print((int)word.charAt(i)-(int)'A' +1);
}
}

Using jQuery the easiest will be:

var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';

var output = $("<div />").html(text).text();
console.log(output);

The keyword global is only useful to change or create global variables in a local context, although creating global variables is seldom considered a good solution.

def bob():
    me = "locally defined"    # Defined only in local context
    print(me)

bob()
print(me)     # Asking for a global variable

The above will give you:

locally defined
Traceback (most recent call last):
  File "file.py", line 9, in <module>
    print(me)
NameError: name 'me' is not defined

While if you use the global statement, the variable will become available "outside" the scope of the function, effectively becoming a global variable.

def bob():
    global me
    me = "locally defined"   # Defined locally but declared as global
    print(me)

bob()
print(me)     # Asking for a global variable

So the above code will give you:

locally defined
locally defined

In addition, due to the nature of python, you could also use global to declare functions, classes or other objects in a local context. Although I would advise against it since it causes nightmares if something goes wrong or needs debugging.

Though it is answered above and it is right to use

<meta name="viewport" content="width=device-width, initial-scale=1">

but if you are using React and webpack then don't forget to close the element tag

<meta name="viewport" content="width=device-width, initial-scale=1" />

referencing to @David answer:

When You want to do soo with another function, eg. html() like in my case, don't forget to add return in new function:

(function() {
    var ev = new $.Event('html'),
        orig = $.fn.html;
    $.fn.html = function() {
        $(this).trigger(ev);
        return orig.apply(this, arguments);
    }
})();

try to use TotalCross. It is a Java Framework to help devs create iOS and Android apps with only one source code. Different from the others platforms, it doesn't require any knowledge in iOS (Objective-C or Swift) nor Android (SDK or NDK)

there is a maven integration https://gitlab.com/totalcross/TotalCross/wikis/building-with-maven

This is what you really want.

<Button
       android:id="@+id/settings"
       android:layout_width="190dp"
       android:layout_height="wrap_content"
       android:layout_gravity="center_horizontal"
       android:background="@color/colorAccent"
       android:drawableStart="@drawable/ic_settings_black_24dp"
       android:paddingStart="40dp"
       android:paddingEnd="40dp"
       android:text="settings"
       android:textColor="#FFF" />

It could be done in Bootstrap 4 using the responsive grid columns. One column for the sidebar and one for the main content.

Bootstrap 4 Sidebar switch to Top Navbar on mobile

<div class="container-fluid h-100">
    <div class="row h-100">
        <aside class="col-12 col-md-2 p-0 bg-dark">
            <nav class="navbar navbar-expand navbar-dark bg-dark flex-md-column flex-row align-items-start">
                <div class="collapse navbar-collapse">
                    <ul class="flex-md-column flex-row navbar-nav w-100 justify-content-between">
                        <li class="nav-item">
                            <a class="nav-link pl-0" href="#">Link</a>
                        </li>
                        ..
                    </ul>
                </div>
            </nav>
        </aside>
        <main class="col">
            ..
        </main>
    </div>
</div>

Alternate sidebar to top
Fixed sidebar to top

For the reverse (Top Navbar that becomes a Sidebar), can be done like this example

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

Solution #1 (Older) (not recommended)

Firstly install ffmpeg-php project (http://ffmpeg-php.sourceforge.net/)

And then you can use of this simple code:

<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
    $gd_image = $frame->toGDImage();
    if ($gd_image) {
        imagepng($gd_image, $thumbnail);
        imagedestroy($gd_image);
        echo '<img src="'.$thumbnail.'">';
    }
}
?>

Description: This project use binary extension .so file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg or PHP.

Solution #2 (Update 2018) (recommended)

Firstly install PHP-FFMpeg project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg)

And then you can use of this simple code:

<?php
require 'vendor/autoload.php';

$sec = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
echo '<img src="'.$thumbnail.'">';

Description: It's newer and more modern project and works with latest version of FFMpeg and PHP. Note that it's required to proc_open() PHP function.

To enable you to use the confirm box like the normal confirm dialog, I would use Promises which will enable you to await on the result of the outcome and then act on this, rather than having to use callbacks.

This will allow you to follow the same pattern you have in other parts of your code with code such as...

  const confirm = await ui.confirm('Are you sure you want to do this?');

  if(confirm){
    alert('yes clicked');
  } else{
    alert('no clicked');
  }

See codepen for example, or run the snippet below.

Below is to check the current limit

csv.field_size_limit()

Out[20]: 131072

Below is to increase the limit. Add it to the code

csv.field_size_limit(100000000)

Try checking the limit again

csv.field_size_limit()

Out[22]: 100000000

Now you won't get the error "_csv.Error: field larger than field limit (131072)"

int values[] = { 23, 1, 5, 78, 22, 4};

double average = ((double) sum) / values.length;

I use the IntelliJ one, because I'm mostly concerned with IntelliJ flagging things that might produce a NPE. I agree that it's frustrating not having a standard annotation in the JDK. There's talk of adding it, it might make it into Java 7. In which case there will be one more to choose from!

if your springfox version higher than 2.5, should be add WebSecurityConfiguration as below:

@Override
public void configure(HttpSecurity http) throws Exception {
    // TODO Auto-generated method stub
    http.authorizeRequests()
        .antMatchers("/v2/api-docs", "/swagger-resources/configuration/ui", "/swagger-resources", "/swagger-resources/configuration/security", "/swagger-ui.html", "/webjars/**").permitAll()
        .and()
        .authorizeRequests()
        .anyRequest()
        .authenticated()
        .and()
        .csrf().disable();
}

In fact, eclipse export will call

java -jar android-sdk-windows\tools\lib\sdklib.jar com.android.sdklib.build.ApkBuilderMain

and then call com.android.sdklib.internal.build.SignedJarBuilder.

Remove/add project file method

This method is entirely aimed at renaming the directory for the project, as viewed in Windows Explorer.

1. Backup your entire project using something like GIT, SVN, or WinZip (important!).
2. Within the solution in Visual Studio, remove the project.
3. Rename the directory in Windows Explorer.
4. Add the project back in again within Visual Studio.

Advantages

• You can make the directory within Windows Explorer match the project name within the solution.

Disadvantages

• If you remove a library, it removes any references to the said library from other projects. The solution may not compile after this until you add the references to said library back in (this is quite easy). This is the reason why step 1 (backup) is so important.
• If you have source control, you will lose the history of the file.

Right-clicking on a project and selecting "Open Folder in Windows Explorer" is useful to keep track of where the project is stored while you are performing this process.

More convenient Swift 3 method:

let documentsUrl = FileManager.default.urls(for: .documentDirectory, 
                                             in: .userDomainMask).first!

I have similar problem. Spring 4 and Tomcat 8. I solve the problem with Spring configuration

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
    <property name="initialSize" value="10" />
    <property name="maxActive" value="25" />
    <property name="maxIdle" value="20" />
    <property name="minIdle" value="10" />
     ...
    <property name="testOnBorrow" value="true" />
    <property name="validationQuery" value="SELECT 1" />
 </bean>

I have tested. It works well! This two line does everything in order to reconnect to database:

<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1" />

In the target's General tab, there is a section called Frameworks, Libraries, and Embedded Content

Click on the + sign, add required framework and the crash is resolved.

I will post right solution at the bottom of the page in case someone is brave (or despaired enough) to read to this point.

Here is gitHub repo for those, who don't want to read all that text: resizableTextView

This works with iOs7 (and I do believe it will work with iOs8) and with autolayout. You don't need magic numbers, disable layout and stuff like that. Short and elegant solution.

I think, that all constraint-related code should go to updateConstraints method. So, let's make our own ResizableTextView.

The first problem we meet here is that don't know real content size before viewDidLoad method. We can take long and buggy road and calculate it based on font size, line breaks, etc. But we need robust solution, so we'll do:

CGSize contentSize = [self sizeThatFits:CGSizeMake(self.frame.size.width, FLT_MAX)];

So now we know real contentSize no matter where we are: before or after viewDidLoad. Now add height constraint on textView (via storyboard or code, no matter how). We'll adjust that value with our contentSize.height:

[self.constraints enumerateObjectsUsingBlock:^(NSLayoutConstraint *constraint, NSUInteger idx, BOOL *stop) {
    if (constraint.firstAttribute == NSLayoutAttributeHeight) {
        constraint.constant = contentSize.height;
        *stop = YES;
    }
}];

The last thing to do is to tell superclass to updateConstraints.

[super updateConstraints];

Now our class looks like:

ResizableTextView.m

- (void) updateConstraints {
    CGSize contentSize = [self sizeThatFits:CGSizeMake(self.frame.size.width, FLT_MAX)];

    [self.constraints enumerateObjectsUsingBlock:^(NSLayoutConstraint *constraint, NSUInteger idx, BOOL *stop) {
        if (constraint.firstAttribute == NSLayoutAttributeHeight) {
            constraint.constant = contentSize.height;
            *stop = YES;
        }
    }];

    [super updateConstraints];
}

Pretty and clean, right? And you don't have to deal with that code in your controllers!

But wait! Y NO ANIMATION!

You can easily animate changes to make textView stretch smoothly. Here is an example:

    [self.view layoutIfNeeded];
    // do your own text change here.
    self.infoTextView.text = [NSString stringWithFormat:@"%@, %@", self.infoTextView.text, self.infoTextView.text];
    [self.infoTextView setNeedsUpdateConstraints];
    [self.infoTextView updateConstraintsIfNeeded];
    [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionLayoutSubviews animations:^{
        [self.view layoutIfNeeded];
    } completion:nil];

you can find how to do it here. In short it is:

public object this[int i]
{
    get { return InnerList[i]; }
    set { InnerList[i] = value; }
}

If you only need a getter the syntax in answer below can be used as well (starting from C# 6).

Info on MySQL's full text search. This is restricted to MyISAM tables, so may not be suitable if you wantto use a different table type.

http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html

Even if WHERE textcolumn LIKE "%SUBSTRING%" is going to be slow, I think it is probably better to let the Database handle it rather than have PHP handle it. If it is possible to restrict searches by some other criteria (date range, user, etc) then you may find the substring search is OK (ish).

If you are searching for whole words, you could pull out all the individual words into a separate table and use that to restrict the substring search. (So when searching for "my search string" you look for the the longest word "search" only do the substring search on records containing the word "search")

Using children

const Wrapper = ({children}) => (
  <div>
    <div>header</div>
    <div>{children}</div>
    <div>footer</div>
  </div>
);

const App = ({name}) => <div>Hello {name}</div>;

const WrappedApp = ({name}) => (
  <Wrapper>
    <App name={name}/>
  </Wrapper>
);

render(<WrappedApp name="toto"/>,node);

This is also known as transclusion in Angular.

children is a special prop in React and will contain what is inside your component's tags (here <App name={name}/> is inside Wrapper, so it is the children

Note that you don't necessarily need to use children, which is unique for a component, and you can use normal props too if you want, or mix props and children:

const AppLayout = ({header,footer,children}) => (
  <div className="app">
    <div className="header">{header}</div>
    <div className="body">{children}</div>
    <div className="footer">{footer}</div>
  </div>
);

const appElement = (
  <AppLayout 
    header={<div>header</div>}
    footer={<div>footer</div>}
  >
    <div>body</div>
  </AppLayout>
);

render(appElement,node);

This is simple and fine for many usecases, and I'd recommend this for most consumer apps.

render props

It is possible to pass render functions to a component, this pattern is generally called render prop, and the children prop is often used to provide that callback.

This pattern is not really meant for layout. The wrapper component is generally used to hold and manage some state and inject it in its render functions.

Counter example:

const Counter = () => (
  <State initial={0}>
    {(val, set) => (
      <div onClick={() => set(val + 1)}>  
        clicked {val} times
      </div>
    )}
  </State>
); 

You can get even more fancy and even provide an object

<Promise promise={somePromise}>
  {{
    loading: () => <div>...</div>,
    success: (data) => <div>{data.something}</div>,
    error: (e) => <div>{e.message}</div>,
  }}
</Promise>

Note you don't necessarily need to use children, it is a matter of taste/API.

<Promise 
  promise={somePromise}
  renderLoading={() => <div>...</div>}
  renderSuccess={(data) => <div>{data.something}</div>}
  renderError={(e) => <div>{e.message}</div>}
/>

As of today, many libraries are using render props (React context, React-motion, Apollo...) because people tend to find this API more easy than HOC's. react-powerplug is a collection of simple render-prop components. react-adopt helps you do composition.

Higher-Order Components (HOC).

const wrapHOC = (WrappedComponent) => {
  class Wrapper extends React.PureComponent {
    render() {
      return (
        <div>
          <div>header</div>
          <div><WrappedComponent {...this.props}/></div>
          <div>footer</div>
        </div>
      );
    }  
  }
  return Wrapper;
}

const App = ({name}) => <div>Hello {name}</div>;

const WrappedApp = wrapHOC(App);

render(<WrappedApp name="toto"/>,node);

An Higher-Order Component / HOC is generally a function that takes a component and returns a new component.

Using an Higher-Order Component can be more performant than using children or render props, because the wrapper can have the ability to short-circuit the rendering one step ahead with shouldComponentUpdate.

Here we are using PureComponent. When re-rendering the app, if the WrappedApp name prop does not change over time, the wrapper has the ability to say "I don't need to render because props (actually, the name) are the same as before". With the children based solution above, even if the wrapper is PureComponent, it is not the case because the children element is recreated everytime the parent renders, which means the wrapper will likely always re-render, even if the wrapped component is pure. There is a babel plugin that can help mitigate this and ensure a constant children element over time.

Conclusion

Higher-Order Components can give you better performance. It's not so complicated but it certainly looks unfriendly at first.

Don't migrate your whole codebase to HOC after reading this. Just remember that on critical paths of your app you might want to use HOCs instead of runtime wrappers for performance reasons, particularly if the same wrapper is used a lot of times it's worth considering making it an HOC.

Redux used at first a runtime wrapper <Connect> and switched later to an HOC connect(options)(Comp) for performance reasons (by default, the wrapper is pure and use shouldComponentUpdate). This is the perfect illustration of what I wanted to highlight in this answer.

Note if a component has a render-prop API, it is generally easy to create a HOC on top of it, so if you are a lib author, you should write a render prop API first, and eventually offer an HOC version. This is what Apollo does with <Query> render-prop component, and the graphql HOC using it.

Personally, I use both, but when in doubt I prefer HOCs because:

• It's more idiomatic to compose them (compose(hoc1,hoc2)(Comp)) compared to render props
• It can give me better performances
• I'm familiar with this style of programming

I don't hesitate to use/create HOC versions of my favorite tools:

• React's Context.Consumer comp
• Unstated's Subscribe
• using graphql HOC of Apollo instead of Query render prop

In my opinion, sometimes render props make the code more readable, sometimes less... I try to use the most pragmatic solution according to the constraints I have. Sometimes readability is more important than performances, sometimes not. Choose wisely and don't bindly follow the 2018 trend of converting everything to render-props.

Look in the file Microsoft.Common.targets

The answer to the question is in the file Microsoft.Common.targets for your target framework version.

For .Net Framework version 4.0 (and 4.5 !) the AssemblySearchPaths-element is defined like this:

    <!--
    The SearchPaths property is set to find assemblies in the following order:

        (1) Files from current project - indicated by {CandidateAssemblyFiles}
        (2) $(ReferencePath) - the reference path property, which comes from the .USER file.
        (3) The hintpath from the referenced item itself, indicated by {HintPathFromItem}.
        (4) The directory of MSBuild's "target" runtime from GetFrameworkPath.
            The "target" runtime folder is the folder of the runtime that MSBuild is a part of.
        (5) Registered assembly folders, indicated by {Registry:*,*,*}
        (6) Legacy registered assembly folders, indicated by {AssemblyFolders}
        (7) Resolve to the GAC.
        (8) Treat the reference's Include as if it were a real file name.
        (9) Look in the application's output folder (like bin\debug)
    -->
<AssemblySearchPaths Condition=" '$(AssemblySearchPaths)' == ''">
  {CandidateAssemblyFiles};
  $(ReferencePath);
  {HintPathFromItem};
  {TargetFrameworkDirectory};
  {Registry:$(FrameworkRegistryBase),$(TargetFrameworkVersion),$(AssemblyFoldersSuffix)$(AssemblyFoldersExConditions)};
  {AssemblyFolders};
  {GAC};
  {RawFileName};
  $(OutDir)
</AssemblySearchPaths>

For .Net Framework 3.5 the definition is the same, but the comment is wrong. The 2.0 definition is slightly different, it uses $(OutputPath) instead of $(OutDir).

On my machine I have the following versions of the file Microsoft.Common.targets:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets

This is with Visual Studio 2008, 2010 and 2013 installed on Windows 7.

The fact that the output directory is searched can be a bit frustrating (as the original poster points out) because it may hide an incorrect HintPath. The solution builds OK on your local machine, but breaks when you build on in a clean folder structure (e.g. on the build machine).

You have a JSON Lines format text file. You need to parse your file line by line:

import json

data = []
with open('file') as f:
    for line in f:
        data.append(json.loads(line))

Each line contains valid JSON, but as a whole, it is not a valid JSON value as there is no top-level list or object definition.

Note that because the file contains JSON per line, you are saved the headaches of trying to parse it all in one go or to figure out a streaming JSON parser. You can now opt to process each line separately before moving on to the next, saving memory in the process. You probably don't want to append each result to one list and then process everything if your file is really big.

If you have a file containing individual JSON objects with delimiters in-between, use How do I use the 'json' module to read in one JSON object at a time? to parse out individual objects using a buffered method.

Another common solution is adding "Other.." option to the drop down and when selected show text box that is otherwise hidden. Then when submitting the form, assign hidden field value with either the drop down or textbox value and in the server side code check the hidden value.

Example: http://jsfiddle.net/c258Q/

HTML code:

Please select: <form onsubmit="FormSubmit(this);">
<input type="hidden" name="fruit" />
<select name="fruit_ddl" onchange="DropDownChanged(this);">
    <option value="apple">Apple</option>
    <option value="orange">Apricot </option>
    <option value="melon">Peach</option>
    <option value="">Other..</option>
</select> <input type="text" name="fruit_txt" style="display: none;" />
<button type="submit">Submit</button>
</form>

JavaScript:

function DropDownChanged(oDDL) {
    var oTextbox = oDDL.form.elements["fruit_txt"];
    if (oTextbox) {
        oTextbox.style.display = (oDDL.value == "") ? "" : "none";
        if (oDDL.value == "")
            oTextbox.focus();
    }
}

function FormSubmit(oForm) {
    var oHidden = oForm.elements["fruit"];
    var oDDL = oForm.elements["fruit_ddl"];
    var oTextbox = oForm.elements["fruit_txt"];
    if (oHidden && oDDL && oTextbox)
        oHidden.value = (oDDL.value == "") ? oTextbox.value : oDDL.value;
}

And in the server side, read the value of "fruit" from the Request.

Yes this is the way:

Right click on your program, select run -> run configuration then on vm argument

-Denv=EnvironmentName -Dcucumber.options="--tags @ifThereisAnyTag"

Then you can apply and close.

First, HTML and PDF are not related although they were created around the same time. HTML is intended to convey higher level information such as paragraphs and tables. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered.

In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.

Because of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". There are three basic things that PDF supports: text, lines/shapes and images. (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Second, iText and iTextSharp parse HTML and CSS. That's it. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Same with DataGridViews, Repeaters, Templates, Views, etc. which are all framework-specific abstractions. It is your responsibility to get the HTML from your choice of framework, iText won't help you. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do.

Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker (Java / .Net). Zero work is being done on HTMLWorker which doesn't support CSS files and has only limited support for the most basic CSS properties and actually breaks on certain tags. If you do not see the HTML attribute or CSS property and value in this file then it probably isn't supported by HTMLWorker. XMLWorker can be more complicated sometimes but those complications also make it more extensible.

Below is C# code that shows how to parse HTML tags into iText abstractions that get automatically added to the document that you are working on. C# and Java are very similar so it should be relatively easy to convert this. Example #1 uses the built-in HTMLWorker to parse the HTML string. Since only inline styles are supported the class="headline" gets ignored but everything else should actually work. Example #2 is the same as the first except it uses XMLWorker instead. Example #3 also parses the simple CSS example.

                    //Parse the HTML
                    iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, msHtml, msCss);
                }
            }


            doc.Close();
        }
    }

    //After all of the PDF "stuff" above is done and closed but **before** we
    //close the MemoryStream, grab all of the active bytes from the stream
    bytes = ms.ToArray();
}

//Now we just need to do something with those bytes.
//Here I'm writing them to disk but if you were in ASP.Net you might Response.BinaryWrite() them.
//You could also write the bytes to a database in a varbinary() column (but please don't) or you
//could pass them to another function for further PDF processing.
var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "test.pdf");
System.IO.File.WriteAllBytes(testFile, bytes);

2017's update

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation this year, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

I am trying to figure out exactly how this works too. This site might be helpful to you. It has all of the possible tags for web.xml along with examples and descriptions of each tag.

http://wiki.metawerx.net/wiki/Web.xml

It's an excellent question, I had the same question yesterday. I thought about this problem, specifically SEARCHED if existed something like "ON UPDATE CASCADE" and fortunately the designers of SQL had also thought about that. I agree with Ted.strauss, and I also commented Noran's case.

When did I use it? Like Ted pointed out, when you are treating several databases at one time, and the modification in one of them, in one table, has any kind of reproduction in what Ted calls "satellite database", can't be kept with the very original ID, and for any reason you have to create a new one, in case you can't update the data on the old one (for example due to permissions, or in case you are searching for fastness in a case that is so ephemeral that doesn't deserve the absolute and utter respect for the total rules of normalization, simply because will be a very short-lived utility)

So, I agree in two points:

(A.) Yes, in many times a better design can avoid it; BUT

(B.) In cases of migrations, replicating databases, or solving emergencies, it's a GREAT TOOL that fortunately was there when I went to search if it existed.

If you're just needing the path of the MDB currently open in the Access UI, I'd suggest writing a function that parses CurrentDB.Name and then stores the result in a Static variable inside the function. Something like this:

Public Function CurrentPath() As String
  Dim strCurrentDBName As String
  Static strPath As String
  Dim i As Integer

  If Len(strPath) = 0 Then
     strCurrentDBName = CurrentDb.Name
     For i = Len(strCurrentDBName) To 1 Step -1
       If Mid(strCurrentDBName, i, 1) = "\" Then
          strPath = Left(strCurrentDBName, i)
          Exit For
       End If
    Next
  End If
  CurrentPath = strPath
End Function

This has the advantage that it only loops through the name one time.

Of course, it only works with the file that's open in the user interface.

Another way to write this would be to use the functions provided at the link inside the function above, thus:

Public Function CurrentPath() As String
  Static strPath As String

  If Len(strPath) = 0 Then
     strPath = FolderFromPath(CurrentDB.Name)
  End If
  CurrentPath = strPath
End Function

This makes retrieving the current path very efficient while utilizing code that can be used for finding the path for any filename/path.

If you don't have avahi installed then it's probably cups.

You put your template in the wrong place. From the Flask docs:

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates

When linger is on but the timeout is zero the TCP stack doesn't wait for pending data to be sent before closing the connection. Data could be lost due to this but by setting linger this way you're accepting this and asking that the connection be reset straight away rather than closed gracefully. This causes an RST to be sent rather than the usual FIN.

Thanks to EJP for his comment, see here for details.

Every time you call the jQuery() function, a new object is created and returned. So even equality checks on the same selectors will fail.

<div id="a">test</div>

$('#a') == $('#a') // false

The resulting jQuery object contains an array of matching elements, which are basically native DOM objects like HTMLDivElement that always refer to the same object, so you should check those for equality using the array index as Darin suggested.

$('#a')[0] == $('#a')[0] // true

Codeigniter generates an "IS NULL" query by just leaving the call with no parameters:

$this->db->where('column');

The generated query is:

WHERE `column` IS NULL

First of all, JDK environment variable settings :

e.g) JAVA_HOME -> C:\develop\java\jdk\jdk1.8.0_25 path -> %JAVA_HOME%\bin;

eclipse Window -> preferences -> Gradle -> Arguments -> Worksapce JRE check -> jdk(jdk1.8.0_25) choice

again Run -> gradle build :)

Use the following code to capture picture using your mobile camera. If you are using android having version higher than Lolipop, You should add the permission request also.

private void cameraIntent()
    {
          Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          startActivityForResult(intent, REQUEST_CAMERA);
    }

@override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
     if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
     }  
} 

Darin Dimitrov's solution worked for me with one exception. When I submitted the partial view with (intentional) validation errors, I ended up with duplicate forms being returned in the dialog:

To fix this I had to wrap the Html.BeginForm in a div:

<div id="myForm">
    @using (Html.BeginForm("CreateDialog", "SupportClass1", FormMethod.Post, new { @class = "form-horizontal" }))
    {
        //form contents
    }
</div>

When the form was submitted, I cleared the div in the success function and output the validated form:

    $('form').submit(function () {
        if ($(this).valid()) {
            $.ajax({
                url: this.action,
                type: this.method,
                data: $(this).serialize(),
                success: function (result) {
                    $('#myForm').html('');
                    $('#result').html(result);
                }
            });
        }
        return false;
    });
});

jQuery has a nice function for removing elements from the DOM.

The closest() function is cool because it will "get the first element that matches the selector by testing the element itself and traversing up through its ancestors."

$(this).closest("tr").remove();

Each delete button could run that very succinct code with a function call.

Try Handle. Filemon & Regmon are also great for trying to figure out what the duce program foo is doing to your system.

public class swaptemp {
    public static void main(String[] args) {
        String s1="10";
        String s2="20";
        String temp;
        System.out.println(s1);
        System.out.println(s2);

        temp=Integer.toString(Integer.parseInt(s1));
        s1=Integer.toString(Integer.parseInt(s2));
        s2=Integer.toString(Integer.parseInt(temp));

        System.out.println(s1);
        System.out.println(s2);
    }
}

test this, you'll find out that there is a line in the code which contains Scan.S() .This is used only for stocking data (String). So just try this:

PS:Don't forget to save the file as bindec

import java.io.*;
class Scan
{        
    public static String S() 
    {
        String x;
    char c;
    boolean erreur;

    do
    {
            x = "";
            erreur = false;

            try
            {
                while((c = (char)System.in.read()) != '\n')
        {
                    if (c != '\r')
                    {
                        x += c;
                    }
                }
            }
            catch(IOException e)
            {
                System.out.print(" > enter String : ");
                erreur = true;
            }
    } while(erreur);

    return x;
    }
public class  bindec{

    public static void main (String[] args) {
        int b=0;
        String a;
        System.out.println("bin: ");
        a = Lire.S();
        int j=a.length()-1;
        for(int i=0;i<a.length() ;i++ ){
            if(a.charAt(i)=='1'){
            b += Math.pow(2,j);
        }
        if(a.charAt(i)=='0'){
            b+=0;
        }
        j=j-1;
    }
        System.out.println("dec: "+b);
    }
}

I understand that this is fairly old question and has some pretty good answers. But, here is my two cents for the sake of completeness.

As per the official documentation, there are four ways, you can allow complete access for robots to access your site.

Clean:

Specify a global matcher with a disallow segment as mentioned by @unor. So your /robots.txt looks like this.

User-agent: *
Disallow:

The hack:

Create a /robots.txt file with no content in it. Which will default to allow all for all type of Bots.

I don't care way:

Do not create a /robots.txt altogether. Which should yield the exact same results as the above two.

The ugly:

From the robots documentation for meta tags, You can use the following meta tag on all your pages on your site to let the Bots know that these pages are not supposed to be indexed.

<META NAME="ROBOTS" CONTENT="NOINDEX">

In order for this to be applied to your entire site, You will have to add this meta tag for all of your pages. And this tag should strictly be placed under your HEAD tag of the page. More about this meta tag here.

I use a simple/minimal solution, one line, cross browser, and works with legacy browsers as well:

/\bmyClass/.test(document.body.className) // notice the \b command for whole word 'myClass'

This method is great because does not require polyfills and if you use them for classList it's much better in terms of performance. At least for me.

Update: I made a tiny polyfill that's an all round solution I use now:

function hasClass(element,testClass){
  if ('classList' in element) { return element.classList.contains(testClass);
} else { return new Regexp(testClass).exec(element.className); } // this is better

//} else { return el.className.indexOf(testClass) != -1; } // this is faster but requires indexOf() polyfill
  return false;
}

For the other class manipulation, see the complete file here.

This should be the answer you are looking for

EmployeeInfo.objects.update_or_create(
    #id or any primary key:value to search for
    identifier=your_id, 
    #if found update with the following or save/create if not found
    defaults={'name':'your_name'}
)

A workaround to consider in a pinch:

1. save a copy of the excel file, modify the column to format type 'text'
2. copy the column values and paste to a text editor, save the file (call it tmp.txt).
3. modify the data in the text file to start and end with a character so that the SQL Server import mechanism will recognize as text. If you have a fancy editor, use included tools. I use awk in cygwin on my windows laptop. For example, I start end end the column value with a single quote, like "$ awk '{print "\x27"$1"\x27"}' ./tmp.txt > ./tmp2.txt"
4. copy and paste the data from tmp2.txt over top of the necessary column in the excel file, and save the excel file
5. run the sql server import for your modified excel file... be sure to double check the data type chosen by the importer is not numeric... if it is, repeat the above steps with a different set of characters

The data in the database will have the quotes once the import is done... you can update the data later on to remove the quotes, or use the "replace" function in your read query, such as "replace([dbo].[MyTable].[MyColumn], '''', '')"

public static void showPyramid(int level)
{
    for(int i=0;i<level;i++)
    {
        for(int j=0;j<level-i-1;j++)
        {
            System.out.print(" ");
        }
        for(int k=level-i;k<=level;k++)
        {
            System.out.print("*");
        }
        for(int k=level-i;k<level;k++)
        {
            System.out.print("*");
        }
        for(int j=0;j<level-i;j++)
        {
            System.out.print(" ");
        }

        System.out.print("\n");
    }

}

Output

     *          
    ***         
   *****        
  *******       
 *********      
***********     

a = [2,3,4,5,6,7,8,9,0]
xyz = [0,12,4,6,242,7,9]  
set(a) & set(xyz)  
set([0, 9, 4, 6, 7])

This question is old but thought I'd add here.. https://www.simple-talk.com/sql/t-sql-programming/dependencies-and-references-in-sql-server/ talks about different options pros and cons and provides stored proc (It_Depends) that produces tree like result of dependencies very similar to SSMS

For those coming here from Google, and for whom the previous answers do not solve the mystery...

If you use XHR to make a server call, but do not return a response, this error will occur.

Example (from Nodejs/React but could equally be js/php):

App.tsx

const handleClickEvent = () => {
    fetch('/routeInAppjs?someVar=someValue&nutherVar=summat_else', {
        method: 'GET',
        mode: 'same-origin',
        credentials: 'include',
        headers: {
          'content-type': 'application/json',
          dataType: 'json',
        },
    }).then((response) => {
        console.log(response)
    });
}

App.js

app.route('/getAllPublicDatasheets').get(async function (req, res) {
    const { someVar, nutherVar } = req.query;
    console.log('Ending here without a return...')
});

Console.log will here report:

Failed to show response data

To fix, add the return response to bottom of your route (server-side):

res.json('Adding this below the console.log in App.js route will solve it.');

Easy solution would be to apply : idxmax() function to get indices of rows with max values. This would filter out all the rows with max value in the group.

In [365]: import pandas as pd

In [366]: df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

In [367]: df                                                                                                       
Out[367]: 
   count  mt   sp  val
0      3  S1  MM1    a
1      2  S1  MM1    n
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
5      1  S4  MM2  dgb
6      2  S2  MM4   rd
7      2  S2  MM4   cb
8      7  S2  MM4  uyi


### Apply idxmax() and use .loc() on dataframe to filter the rows with max values:
In [368]: df.loc[df.groupby(["sp", "mt"])["count"].idxmax()]                                                       
Out[368]: 
   count  mt   sp  val
0      3  S1  MM1    a
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
8      7  S2  MM4  uyi

### Just to show what values are returned by .idxmax() above:
In [369]: df.groupby(["sp", "mt"])["count"].idxmax().values                                                        
Out[369]: array([0, 2, 3, 4, 8])

No, because RAND_MAX is typically expanded to MAX_INT. So adding one (apparently) puts it at MIN_INT (although it should be undefined behavior as I'm told), hence the reversal of sign.

To get what you want you will need to move the +1 outside the computation:

r = ((double) rand() / (RAND_MAX)) + 1;

Just run:

$ git update-git-for-windows

Using lambdas one can perform the following:

{
   std::map<std::string,int> m;
   std::vector<int> v;
   v.reserve(m.size());
   std::for_each(m.begin(),m.end(),
                 [&v](const std::map<std::string,int>::value_type& p) 
                 { v.push_back(p.second); });
}

Most browsers don't display the custom message passed to confirm().

With this method, you can show a popup with a custom message if your user changed the value of any <input> field.

You can apply this only to some links, or even other HTML elements in your page. Just add a custom class to all the links that need confirmation and apply use the following code:

$(document).ready(function() {_x000D_
  let unsaved = false;_x000D_
  // detect changes in all input fields and set the 'unsaved' flag_x000D_
  $(":input").change(() => unsaved = true);_x000D_
  // trigger popup on click_x000D_
  $('.dangerous-link').click(function() {_x000D_
    if (unsaved && !window.confirm("Are you sure you want to nuke the world?")) {_x000D_
      return; // user didn't confirm_x000D_
    }_x000D_
    // either there are no unsaved changes or the user confirmed_x000D_
    window.location.href = $(this).data('destination');_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<input type="text" placeholder="Nuclear code here" />_x000D_
<a data-destination="https://en.wikipedia.org/wiki/Boom" class="dangerous-link">_x000D_
    Launch nuke!_x000D_
</a>

Try changing the input value in the example to get a preview of how it works.

No requires converting the Task to int. Simply Use The Task Result.

int taskResult = AccessTheWebAndDouble().Result;

public async Task<int> AccessTheWebAndDouble()
{
    int task = AccessTheWeb();
    return task;
}

It will return the value if available otherwise it return 0.

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

Reference https://docs.spring.io/spring-boot/docs/1.2.0.RELEASE/reference/html/common-application-properties.html

From python 3.x, the unified integer libries are even more smarter than older versions. On my (i7 Ubuntu) box I got the following,

>>> type(math.factorial(30))
<class 'int'>

For implementation details refer Include/longintrepr.h, Objects/longobject.c and Modules/mathmodule.c files. The last file is a dynamic module (compiled to an so file). The code is well commented to follow.

Use this SQL to get the first 2000 chars of the BLOB.

SELECT utl_raw.cast_to_varchar2(dbms_lob.substr(<YOUR_BLOB_FIELD>,2000,1)) FROM <YOUR_TABLE>;

Note: This is because, Oracle will not be able to handle the conversion of BLOB that is more than length 2000.

This seems to work:

$("#theSelect").change(function(){          
    var value = $("#theSelect option:selected").val();
    var theDiv = $(".is" + value);

    theDiv.slideDown().removeClass("hidden");
    //Add this...
    $("#theSelect option:selected").attr('disabled', 'disabled');
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    //...and this.
    $("#theSelect option:disabled").removeAttr('disabled');
});

Here's the shortest code that will do the job:

from pandas import DataFrame
df = DataFrame(resoverall.fetchall())
df.columns = resoverall.keys()

You can go fancier and parse the types as in Paul's answer.

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. But i think ini_set() helps you to change the values in php.ini during run time.

I found applying the network and rebooting both the nodes did the trick for me.

kubectl apply -f [podnetwork].yaml

One of the case

SessionFactory sf=new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();

UserDetails user=new UserDetails();

session.beginTransaction();
user.setUserName("update user agian");
user.setUserId(12);
session.saveOrUpdate(user);
session.getTransaction().commit();
System.out.println("user::"+user.getUserName());

sf.close();

I am answering bit late to this question, but someone, in future, might find this useful. The below approach, besides lots of other approaches, works best, and I personally think would better suit a web application.

@Configuration
@EnableWebMvc
public class WebConfiguration extends WebMvcConfigurerAdapter {

 ... other configurations

@Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
        builder.serializationInclusion(JsonInclude.Include.NON_NULL);
        builder.propertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
        builder.serializationInclusion(Include.NON_EMPTY);
        builder.indentOutput(true).dateFormat(new SimpleDateFormat("yyyy-MM-dd"));
        converters.add(new MappingJackson2HttpMessageConverter(builder.build()));
        converters.add(new MappingJackson2XmlHttpMessageConverter(builder.createXmlMapper(true).build()));
    }
}

With the advent of Django 1.7, there is now a new update_or_create QuerySet method, which should do exactly what you want. Just be careful of potential race conditions if uniqueness is not enforced at the database level.

Example from the documentation:

obj, created = Person.objects.update_or_create(
    first_name='John', last_name='Lennon',
    defaults={'first_name': 'Bob'},
)

The update_or_create method tries to fetch an object from database based on the given kwargs. If a match is found, it updates the fields passed in the defaults dictionary.

Pre-Django 1.7:

Change the model field values as appropriate, then call .save() to persist the changes:

try:
    obj = Model.objects.get(field=value)
    obj.field = new_value
    obj.save()
except Model.DoesNotExist:
    obj = Model.objects.create(field=new_value)
# do something else with obj if need be

To inject an Object, its class must be known to the CDI mechanism. Usualy adding the @Named annotation will do the trick.

try using

npm rebuild node-sass

Yes, you can do this using introspection. Make a GraphQL query like (for type UserType)

{
   __type(name:"UserType") {
      fields {
         name
         description
      }  
   }
}

and you'll get a response like (actual field names will depend on your actual schema/type definition)

{
  "data": {
    "__type": {
      "fields": [
        {
          "name": "id",
          "description": ""
        },
        {
          "name": "username",
          "description": "Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only."
        },
        {
          "name": "firstName",
          "description": ""
        },
        {
          "name": "lastName",
          "description": ""
        },
        {
         "name": "email",
          "description": ""
        },
        ( etc. etc. ...)
      ]
    }
  }
}

You can then read this list of fields in your client and dynamically build a second GraphQL query to get all of these fields.

This relies on you knowing the name of the type that you want to get the fields for -- if you don't know the type, you could get all the types and fields together using introspection like

{
  __schema {
    types {
      name
      fields {
        name
        description
      }
    }
  }
}

NOTE: this is the over-the-wire GraphQL data -- you're on your own to figure out how to read and write with your actual client. Your graphQL javascript library may already employ introspection in some capacity, for example the apollo codegen command uses introspection to generate types.

If you are using a modern browser there's a simple solution.

First, attach a template variable to the input.

<input type="date" #date />

Then pass the variable into your receiving method.

<button (click)="submit(date)"></button>

In your controller just accept the parameter as type HTMLInputElement and use the method valueAsDate on the HTMLInputElement.

submit(date: HTMLInputElement){
    console.log(date.valueAsDate);
}

You can then manipulate the date anyway you would a normal date.

You can also set the value of your <input [value]= "..."> as you would normally.

Personally, as someone trying to stay true to the unidirectional data flow, i try to stay away from two way data binding in my components.

Homework question? Well you can modify your original 'right triangle' code to generate an inverted 'right triangle' with spaces So that'll be like

for(i=0; i<6; i++)
{
    for(j=6; j>=(6-i); j--)
    {
        print(" ");
    }
    for(x=0; x<=((2*i)+1); x++)
    {
        print("*");
    }
    print("\n");
}

you can use this way...

listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                final int position, long id) {

          String main = listView.getSelectedItem().toString();
        }
    });

I always use

document.getElementsByTagName('html')[0].innerHTML

Probably not the right way but I can understand it when I see it.

You don't need regex for this

>>> s = "Username: How are you today?"

You can use the split method to split the string on the ':' character

>>> s.split(':')
['Username', ' How are you today?']

And slice out element [0] to get the first part of the string

>>> s.split(':')[0]
'Username'

android:maxLines="1"
android:inputType="text"

Add the above code to have a single line in EditText tag in your layout.

android:singleLine="true" is deprecated

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

 private void HighLightGridRows()
 {            
     Debugger.Launch();
     for (int i = 0; i < dtgvAppSettings.Rows.Count; i++)
     {
         String key = dtgvAppSettings.Rows[i].Cells["Key"].Value.ToString();
         if (key.ToLower().Contains("applicationpath") == true)
         {
             dtgvAppSettings.Rows[i].DefaultCellStyle.BackColor = Color.Yellow;
         }
     }
 }

Regardless to Your example

select length('Burger') from dual;

I hope this will help :)

<a href="javascript:void(0);"></a>

javascript: tells the browser going to write javascript code

Please walk me through the commands I should run to figure this out.

The simplest test you can do is to perform 1000 requests, 10 at a time (which approximately simulates 10 concurrent users getting 100 pages each - over the length of the test).

ab -n 1000 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://www.example.com/

-n 1000 is the number of requests to make.

-c 10 tells AB to do 10 requests at a time, instead of 1 request at a time, to better simulate concurrent visitors (vs. sequential visitors).

-k sends the KeepAlive header, which asks the web server to not shut down the connection after each request is done, but to instead keep reusing it.

I'm also sending the extra header Accept-Encoding: gzip, deflate because mod_deflate is almost always used to compress the text/html output 25%-75% - the effects of which should not be dismissed due to it's impact on the overall performance of the web server (i.e., can transfer 2x the data in the same amount of time, etc).

Multiply that by 60, and you have your requests per minute.

To get real world results, you'll want to test Wordpress instead of some static HTML or index.php file because you need to know how everything performs together: including complex PHP code, and multiple MySQL queries...

For example here is the results of testing a fresh install of Wordpress on the same system and WAMP environment (I'm using WampDeveloper, but there are also Xampp, WampServer, and others)...

Requests per second:    18.68 [#/sec] (mean)

That's 37x slower now!

After the load test, there are a number of things you can do to improve the overall performance (Requests Per Second), and also make the web server more stable under greater load (e.g., increasing the -n and the -c tends to crash Apache), that you can read about here:

Load Testing Apache with AB (Apache Bench)

Well, if user write 1,00,000 then floatvar will show error. So -

floatval(preg_replace("/[^-0-9\.]/","",$input));

This is much more reliable.

Usage :

$input = '1,03,24,23,434,500.6798633 this';
echo floatval(preg_replace("/[^-0-9\.]/","",$input));

It's a formal way of specifying a correlation name for an entity so that you can address it easily in another part of the query.

That’s because j+3 doesn’t change the value of j. You need to replace that with j = j + 3 or j += 3 so that the value of j is increased by 3:

for (j = 0; j <= 90; j += 3) { }

It is posible. My android device version is 4.0.4 and android.os.Build.VERSION.SDK_INT is 15

I have 3 spinners

Spinner c_fruit=(Spinner) findViewById(R.id.fruits);
Spinner c_vegetable=(Spinner) findViewById(R.id.vegetables);
Spinner c_beverage=(Spinner) findViewById(R.id.beverages);

And also I have a Async-Tack class.

Here is my spinner loading code

RequestSend reqs_fruit = new RequestSend(this);
reqs_fruit.where="Get_fruit_List";
reqs_fruit.title="Loading fruit";
reqs_fruit.execute();

RequestSend reqs_vegetable = new RequestSend(this);
reqs_vegetable.where="Get_vegetable_List";
reqs_vegetable.title="Loading vegetable";
reqs_vegetable.execute();

RequestSend reqs_beverage = new RequestSend(this);
reqs_beverage.where="Get_beverage_List";
reqs_beverage.title="Loading beverage";
reqs_beverage.execute();

This is working perfectly. One by one my spinners loaded. I didn't user executeOnExecutor.

You must have an empty line in your file.

You may want to wrap your parseInt calls in a "try" block:

try {
  tall[i++] = Integer.parseInt(s);
}
catch (NumberFormatException ex) {
  continue;
}

Or simply check for empty strings before parsing:

if (s.length() == 0) 
  continue;

Note that by initializing your index variable i inside the loop, it is always 0. You should move the declaration before the while loop. (Or make it part of a for loop.)

Having tried everything in vain, I discovered that in my case it wasn't working because an incorrect attribute value in Web Project csproj file. When I change ToolsVersion to 14, which matches my current IDE version (i.e. Visual Studio 2015), everything worked like a charm:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition=

My solution for a cache implementation that stores optional NSAttributedString:

public static var attributedMessageTextCache    = [String: NSAttributedString?]()

    if attributedMessageTextCache.index(forKey: "key") != nil
    {
        if let attributedMessageText = TextChatCache.attributedMessageTextCache["key"]
        {
            return attributedMessageText
        }
        return nil
    }

    TextChatCache.attributedMessageTextCache["key"] = .some(.none)
    return nil

The dataset:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

Now you can convert the data frame into a matrix and use the barplot function.

barplot(as.matrix(dat))

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

Well you can hide the close button by changing the FormBorderStyle from the properties section or programmatically in the constructor using:

public Form1()
{
InitializeComponent();
this.FormBorderStyle = FormBorderStyle.None;
}

then you create a menu strip item to exit the application.

You can create table variable instead of tamp table in procedure A and execute procedure B and insert into temp table by below query.

DECLARE @T TABLE
(
TABLE DEFINITION
)
.
.
.
INSERT INTO @T
EXEC B @MYDATE

and you continue operation.

You need the Apache Commons Codec library 1.4 or above in your classpath. This library contains Base64 implementation.

Its Shift + Alt + 2 to split into 2 screens. More options are found under the menu item View -> Layout.
Once the screen is split, you can open files using the shortcuts:

JpaRepository extends PagingAndSortingRepository which in turn extends CrudRepository.

Their main functions are:

• CrudRepository mainly provides CRUD functions.
• PagingAndSortingRepository provides methods to do pagination and sorting records.
• JpaRepository provides some JPA-related methods such as flushing the persistence context and deleting records in a batch.

Because of the inheritance mentioned above, JpaRepository will have all the functions of CrudRepository and PagingAndSortingRepository. So if you don't need the repository to have the functions provided by JpaRepository and PagingAndSortingRepository , use CrudRepository.

To add controls dynamically to the form, do the following code. Here we are creating textbox controls to add dynamically.

Public Class Form1
    Private m_TextBoxes() As TextBox = {}

    Private Sub Button1_Click(ByVal sender As System.Object, _
                              ByVal e As System.EventArgs) _
                              Handles Button1.Click

        ' Get the index for the new control.
        Dim i As Integer = m_TextBoxes.Length

        ' Make room.
        ReDim Preserve m_TextBoxes(i)

        ' Create and initialize the control.
        m_TextBoxes(i) = New TextBox
        With m_TextBoxes(i)
            .Name = "TextBox" & i.ToString()
            If m_TextBoxes.Length < 2 Then
                ' Position the first one.
                .SetBounds(8, 8, 100, 20)
            Else
                ' Position subsequent controls.
                .Left = m_TextBoxes(i - 1).Left
                .Top = m_TextBoxes(i - 1).Top + m_TextBoxes(i - _
                    1).Height + 4
                .Size = m_TextBoxes(i - 1).Size
            End If

            ' Save the control's index in the Tag property.
            ' (Or you can get this from the Name.)
            .Tag = i
        End With

        ' Give the control an event handler.
        AddHandler m_TextBoxes(i).TextChanged, AddressOf TextBox_TextChanged

        ' Add the control to the form.
        Me.Controls.Add(m_TextBoxes(i))
    End Sub

    'When you enter text in one of the TextBoxes, the TextBox_TextChanged event
    'handler displays the control's name and its current text.
    Private Sub TextBox_TextChanged(ByVal sender As  _
    System.Object, ByVal e As System.EventArgs)
        ' Display the current text.
        Dim txt As TextBox = DirectCast(sender, TextBox)
        Debug.WriteLine(txt.Name & ": [" & txt.Text & "]")

Just a quick addition. If you're using the new analytics.js, then:

var track = function() {     
 ga('send', 'pageview', {'page': $location.path()});                
};

Additionally one tip is that google analytics will not fire on localhost. So if you are testing on localhost, use the following instead of the default create (full documentation)

ga('create', 'UA-XXXX-Y', {'cookieDomain': 'none'});

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

As early as possible in your application, require and configure dotenv.

require('dotenv').config()

Referencing a channel within a conversation

To create a clickable reference to a channel in a Slack conversation, just type # followed by the channel name. For example: #general.

To grab a link to a channel through the Slack UI

To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:

The link would look like this:

https://yourteam.slack.com/messages/C69S1L3SS

Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.

To compose a URL for a channel based on channel name

https://yourteam.slack.com/channels/<channel_name>

Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.

To compose a URL for a direct message (DM) channel to a user

https://yourteam.slack.com/channels/<username>

If you are using Symfony there's a great rest client bundle that even includes all of the ~100 exceptions and throws them instead of returning some meaningless error code + message.

You should really check it: https://github.com/CircleOfNice/CiRestClientBundle

I love the interface:

try {
    $restClient = new RestClient();
    $response   = $restClient->get('http://www.someUrl.com');
    $statusCode = $response->getStatusCode();
    $content    = $response->getContent();
} catch(OperationTimedOutException $e) {
    // do something
}

Works for all http methods.

Here is how to build a function that returns a result set that can be queried as if it were a table:

SQL> create type emp_obj is object (empno number, ename varchar2(10));
  2  /

Type created.

SQL> create type emp_tab is table of emp_obj;
  2  /

Type created.

SQL> create or replace function all_emps return emp_tab
  2  is
  3     l_emp_tab emp_tab := emp_tab();
  4     n integer := 0;
  5  begin
  6     for r in (select empno, ename from emp)
  7     loop
  8        l_emp_tab.extend;
  9        n := n + 1;
 10       l_emp_tab(n) := emp_obj(r.empno, r.ename);
 11     end loop;
 12     return l_emp_tab;
 13  end;
 14  /

Function created.

SQL> select * from table (all_emps);

You can make a directory "fonts" in a root of your project and put your fonts (sans_serif.ttf) file there. Then you can make something like this:

fonts_path = os.path.join(os.path.dirname(os.path.dirname(__file__)), 'fonts')
font = ImageFont.truetype(os.path.join(fonts_path, 'sans_serif.ttf'), 24)

SOLUTION: to prevent this error(for AWS LAMBDA):

In order to exit of "Nodejs event Loop" you must end the connection, and then reconnect. Add the next code to invoke the callback:

connection.end( function(err) {
        if (err) {console.log("Error ending the connection:",err);}

       //  reconnect in order to prevent the"Cannot enqueue Handshake after invoking quit"

         connection = mysql.createConnection({
                host     : 'rds.host',
                port     :  3306,
                user     : 'user',
               password : 'password',
               database : 'target database'

               });
        callback(null, {
            statusCode: 200,
            body: response,

        });
    });

If you had all the branches to delete in a text file (branches-to-del.txt) (one branch per line), then you could do this to delete all such branches from the remote (origin): xargs -a branches-to-del.txt git push --delete origin

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

This happens when accessing a package scoped method of a class that is in the same package but is in a different jar and classloader.

This was my source, but the link is now broken. Following is full text from google cache:

Packages (as in package access) are scoped per ClassLoader.

You state that the parent ClassLoader loads the interface and the child ClassLoader loads the implementation. This won't work because of the ClassLoader-specific nature of package scoping. The interface isn't visible to the implementation class because, even though it's the same package name, they're in different ClassLoaders.

I only skimmed the posts in this thread, but I think you've already discovered that this will work if you declare the interface to be public. It would also work to have both interface and implementation loaded by the same ClassLoader.

Really, if you expect arbitrary folks to implement the interface (which you apparently do if the implementation is being loaded by a different ClassLoader), then you should make the interface public.

The ClassLoader-scoping of package scope (which applies to accessing package methods, variables, etc.) is similar to the general ClassLoader-scoping of class names. For example, I can define two classes, both named com.foo.Bar, with entirely different implementation code if I define them in separate ClassLoaders.

In Excel for Mac 2016 at least,if you place the labels in any spot on the graph and are looking to move them anywhere else (in this case above the bars), select:

Chart Design->Add Chart Element->Data Labels -> More Data Label Options

then you can grab each individual label and pull it where you would like it.

 ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

then add elements for each pair

 nameValuePairs.add(new BasicNameValuePair("yourReqVar", Value);
 nameValuePairs.add( ..... );

Then use the HttpPost:

HttpPost httppost = new HttpPost(URL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

and use the HttpClient and Response to get the response from the server

I came across this method and I use it to make div IDs the slug name inside the loop:

<?php $slug = basename( get_permalink() ); echo $slug;?>

In code level also, you could add your lib to the project using the compiler directives #pragma.

example:

#pragma comment( lib, "yourLibrary.lib" )

#right { 
  background-color: red;
  height: 300px;
  width: 300px;
  z-index: 9999;
  margin-top: 0px;
  position: absolute;
  top:0;
  right:0;
}

position: absolute; top:0; right:0; do the work here! :) Also remove the floating!

Directly assign the value to model in data-ng-value attribute. Since Angular interpreter doesn't recognize hidden fields as part of ngModel.

<input type="hidden" name="pfuserid" data-ng-value="newPortfolio.UserId = data.Id"/>

anyObject() should fit your needs.

Also, you can always consider implementing hashCode() and equals() for the Bazoo class. This would make your code example work the way you want.

Add following code to the 'activity' of Manifest file.

android:windowSoftInputMode="adjustResize"
