If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:

Range(firstcol & firstrow & ":" & secondcol & secondrow).Select

You can define a mutable above the scope of the threaded function, and add the result to that. (I also modified the code to be python3 compatible)

returns = {}
def foo(bar):
    print('hello {0}'.format(bar))
    returns[bar] = 'foo'

from threading import Thread
t = Thread(target=foo, args=('world!',))
t.start()
t.join()
print(returns)

This returns {'world!': 'foo'}

If you use the function input as the key to your results dict, every unique input is guaranteed to give an entry in the results

Use the \ character to escape a character that has special meaning inside a regular expression.

To automate it, you could use this:

function escapeRegExp(text) {
  return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
}

Update: There is now a proposal to standardize this method, possibly in ES2016: https://github.com/benjamingr/RegExp.escape

Update: The abovementioned proposal was rejected, so keep implementing this yourself if you need it.

I got your problem , and here is my answer:

prices = [5, 12, 45]
list=['1','2','3']

for i in range(1,3):
  vars()["prices"+list[0]]=prices[0]
print ("prices[i]=" +prices[i])

so while printing:

price1 = 5 
price2 = 12
price3 = 45

You haven't provided enough context to provide an accurate answer (i.e. how do you want to handle identical keys in multiple dicts?)

One answer is to iterate the list, and attempt to get 'd'

mylist = [{'a': 1, 'b': 2}, {'c': 3, 'd': 4}, {'e': 5, 'f': 6}]
myvalues = [i['d'] for i in mylist if 'd' in i]

Another answer is to access the dict directly (by list index), though you have to know that the key is present

mylist[1]['d']

I changed the line

.ui-helper-hidden-accessible { position: absolute !important; clip: rect(1px 1px 1px 1px); clip: rect(1px,1px,1px,1px); }

to

.ui-helper-hidden-accessible { position: absolute !important; }

and everything works now. Otherwise try upping the z-index as Soldierflup suggested.

Downloading Wget is not necessary; the .NET Framework has web client classes built in.

$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")

Good question here. I think you cannot terminate the script execution. Although I have never looked for it, I have been using the chrome debugger for quite a long time at work. I usually set breakpoints in my javascript code and then I debug the portion of code I'm interested in. When I finish debugging that code, I usually just run the rest of the program or refresh the browser.

If you want to prevent the rest of the script from being executed (e.g. due to AJAX calls that are going to be made) the only thing you can do is to remove that code in the console on-the-fly, thus preventing those calls from being executed, then you could execute the remaining code without problems.

I hope this helps!

P.S: I tried to find out an option for terminating the execution in some tutorials / guides like the following ones, but couldn't find it. As I said before, probably there is no such option.

Your android app needs to correct 12-digit number id (aka GCM Project Number). If this 12-digit number is incorrect, then you will also get this error.

This 12-digit number is found in your Google Play Console under your specific app, 'Service & API' -> 'LINKED SENDER IDS'

CMake favours passing the full path to link libraries, so assuming libbingitup.a is in ${CMAKE_SOURCE_DIR}, doing the following should succeed:

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

I'm using this to address the security implications noted in @CMS's answer.

// example 1: www.example.com/index.html#foo

// load correct subpage from URL hash if it exists
$(window).on('load', function () {
    var hash = window.location.hash;
    if (hash) {
        hash = hash.replace('#',''); // strip the # at the beginning of the string
        hash = hash.replace(/([^a-z0-9]+)/gi, '-'); // strip all non-alphanumeric characters
        hash = '#' + hash; // hash now equals #foo with example 1

        // do stuff with hash
        $( 'ul' + hash + ':first' ).show();
        // etc...
    }
});

This should do it:

^/\b([a-z0-9]+)\b(?<!ignoreme|ignoreme2|ignoreme3)

You can add as much ignored words as you like, here is a simple PHP implementation:

$ignoredWords = array('ignoreme', 'ignoreme2', 'ignoreme...');

preg_match('~^/\b([a-z0-9]+)\b(?<!' . implode('|', array_map('preg_quote', $ignoredWords)) . ')~i', $string);

After making above improvement such as checking if mysql service is running or not, you just need to give a small password while creating connection, it is ' ' or 1 time press on space-bar in case of GUI or workbench. After which you just need to validate your machine with server (validated HOST). For that purpose click on 'New Server Instance' and it will configure server/HOST on your behalf itself.

I have done this successfully just a few couple of minutes ago. My workbench software is able to show all pre-installed databases etc now.

hope it will work for you as well.

Thanks!!!

If []byte is ASCII byte numbers then first convert the []byte to string and use the strconv package Atoi method which convert string to int.

package main
import (
    "fmt"
    "strconv"
)

func main() {
    byteNumber := []byte("14")
    byteToInt, _ := strconv.Atoi(string(byteNumber))
    fmt.Println(byteToInt)
}

I figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared

In addition to @jalchr's solution that helped me, I found that when calling ATL::Base64Encode from a c++ application to encode the content you pass to an ASP.NET webservice, you need something else, too. In addition to

sEncryptedString = sEncryptedString.Replace(' ', '+'); 

from @jalchr's solution, you also need to ensure that you do not use the ATL_BASE64_FLAG_NOPAD flag on ATL::Base64Encode:

 BOOL bEncoded = Base64Encode(lpBuffer,
                    nBufferSizeInBytes,
                    strBase64Encoded.GetBufferSetLength(base64Length),
                    &base64Length,ATL_BASE64_FLAG_NOCRLF/*|ATL_BASE64_FLAG_NOPAD*/);

It is configured to use localhost:25 for the mail server.

The error message says that it can't connect to localhost:25.

Therefore you have two options:

1. Install / Properly configure an SMTP server on localhost port 25
2. Change the configuration to point to some other SMTP server that you can connect to

Try to avoid using null in Scala. It's really there only for interoperability with Java. In Scala, use Option for things that might be empty. If you're calling a Java API method that might return null, wrap it in an Option immediately.

def getObject : Option[QueueObject] = {
  // Wrap the Java result in an Option (this will become a Some or a None)
  Option(someJavaObject.getResponse)
}

Note: You don't need to put it in a val or use an explicit return statement in Scala; the result will be the value of the last expression in the block (in fact, since there's only one statement, you don't even need a block).

def getObject : Option[QueueObject] = Option(someJavaObject.getResponse)

Besides what the others have already shown (for example calling foreach on the Option, which might be slightly confusing), you could also call map on it (and ignore the result of the map operation if you don't need it):

getObject map QueueManager.add

This will do nothing if the Option is a None, and call QueueManager.add if it is a Some.

I find using a regular if however clearer and simpler than using any of these "tricks" just to avoid an indentation level. You could also just write it on one line:

if (getObject.isDefined) QueueManager.add(getObject.get)

or, if you want to deal with null instead of using Option:

if (getObject != null) QueueManager.add(getObject)

edit - Ben is right, be careful to not call getObject more than once if it has side-effects; better write it like this:

val result = getObject
if (result.isDefined) QueueManager.add(result.get)

or:

val result = getObject
if (result != null) QueueManager.add(result)

You use the built-in int function, and pass it the base of the input number, i.e. 2 for a binary number:

>>> int('11111111', 2)
255

Here is documentation for python2, and for python3.

Further to Ryan's answer you will also need to set the DataColumn's Ordinal property if you are dealing with a table-valued parameter with multiple columns whose ordinals are not in alphabetical order.

As an example, if you have the following table value that is used as a parameter in SQL:

CREATE TYPE NodeFilter AS TABLE (
  ID int not null
  Code nvarchar(10) not null,
);

You would need to order your columns as such in C#:

table.Columns["ID"].SetOrdinal(0);
// this also bumps Code to ordinal of 1
// if you have more than 2 cols then you would need to set more ordinals

If you fail to do this you will get a parse error, failed to convert nvarchar to int.

Another option is to left join your Results table with your existing competitors Table and find the new competitors by filtering the distinct records that don´t match int the join:

INSERT Competitors (cName)
SELECT  DISTINCT cr.Name
FROM    CompResults cr left join
        Competitors c on cr.Name = c.cName
where   c.cName is null

New syntax MERGE also offer a compact, elegant and efficient way to do that:

MERGE INTO Competitors AS Target
USING (SELECT DISTINCT Name FROM CompResults) AS Source ON Target.Name = Source.Name
WHEN NOT MATCHED THEN
    INSERT (Name) VALUES (Source.Name);

Allow the default HTTP and HTTPS port, ports 80 and 443, through firewalld:

sudo firewall-cmd --permanent --add-port=80/tcp
sudo firewall-cmd --permanent --add-port=443/tcp

And reload the firewall:

• After looking at a number of solutions on this thread and elsewhere the following code was put together. This is only to read a property.
• I could not get the Shell32.FolderItem2.ExtendedProperty function to work, it is supposed to take a string value and return the correct value and type for that property... this was always null for me and developer reference resources were very thin.
• The WindowsApiCodePack seems to have been abandoned by Microsoft which brings us the code below.

Use:

string propertyValue = GetExtendedFileProperty("c:\\temp\\FileNameYouWant.ext","PropertyYouWant");

1. Will return you the value of the extended property you want as a string for the given file and property name.
2. Only loops until it found the specified property - not until all properties are discovered like some sample code

3. Will work on Windows versions like Windows server 2008 where you will get the error "Unable to cast COM object of type 'System.__ComObject' to interface type 'Shell32.Shell'" if just trying to create the Shell32 Object normally.

   public static string GetExtendedFileProperty(string filePath, string propertyName)
   {
       string value = string.Empty;
       string baseFolder = Path.GetDirectoryName(filePath);
       string fileName = Path.GetFileName(filePath);
   
       //Method to load and execute the Shell object for Windows server 8 environment otherwise you get "Unable to cast COM object of type 'System.__ComObject' to interface type 'Shell32.Shell'"
       Type shellAppType = Type.GetTypeFromProgID("Shell.Application");
       Object shell = Activator.CreateInstance(shellAppType);
       Shell32.Folder shellFolder = (Shell32.Folder)shellAppType.InvokeMember("NameSpace", System.Reflection.BindingFlags.InvokeMethod, null, shell, new object[] { baseFolder });
   
       //Parsename will find the specific file I'm looking for in the Shell32.Folder object
       Shell32.FolderItem folderitem = shellFolder.ParseName(fileName);
       if (folderitem != null)
       {
           for (int i = 0; i < short.MaxValue; i++)
           {
               //Get the property name for property index i
               string property = shellFolder.GetDetailsOf(null, i);
   
               //Will be empty when all possible properties has been looped through, break out of loop
               if (String.IsNullOrEmpty(property)) break;
   
               //Skip to next property if this is not the specified property
               if (property != propertyName) continue;    
   
               //Read value of property
               value = shellFolder.GetDetailsOf(folderitem, i);
           }
       }
       //returns string.Empty if no value was found for the specified property
       return value;
   }
   

No restart, no BIOS needed in my case. I have downloaded and installed the latest version of HAXM from the releases: HAXM releases

Here's my solution, i would love anyone's opinion on this, it's simple for beginners

import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.spec.InvalidKeySpecException;
import java.security.spec.KeySpec;
import java.util.Base64;
import java.util.Base64.Encoder;
import java.util.Scanner;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.PBEKeySpec;

public class Cryptography {

    public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeySpecException {
        Encoder encoder = Base64.getUrlEncoder().withoutPadding();
        System.out.print("Password: ");
        String strPassword = new Scanner(System.in).nextLine();
        byte[] bSalt = Salt();
        String strSalt = encoder.encodeToString(bSalt); // Byte to String
        System.out.println("Salt: " + strSalt);
        System.out.println("String to be hashed: " + strPassword + strSalt);
        String strHash = encoder.encodeToString(Hash(strPassword, bSalt)); // Byte to String
        System.out.println("Hashed value (Password + Salt value): " + strHash);
    }

    private static byte[] Salt() {
        SecureRandom random = new SecureRandom();
        byte salt[] = new byte[6];
        random.nextBytes(salt);
        return salt;
    }

    private static byte[] Hash(String password, byte[] salt) throws NoSuchAlgorithmException, InvalidKeySpecException {
        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 65536, 128);
        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
        byte[] hash = factory.generateSecret(spec).getEncoded();
        return hash;
    }

}

You can validate by just decoding the strSalt and using the same hash method:

public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeySpecException {
        Encoder encoder = Base64.getUrlEncoder().withoutPadding();
        Decoder decoder = Base64.getUrlDecoder();
        System.out.print("Password: ");
        String strPassword = new Scanner(System.in).nextLine();
        String strSalt = "Your Salt String Here";
        byte[] bSalt = decoder.decode(strSalt); // String to Byte
        System.out.println("Salt: " + strSalt);
        System.out.println("String to be hashed: " + strPassword + strSalt);
        String strHash = encoder.encodeToString(Hash(strPassword, bSalt)); // Byte to String
        System.out.println("Hashed value (Password + Salt value): " + strHash);
    }

to stop IIS manually:

1. go to start menu
2. type in IIS

you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.

If you don't want IIS to start on startup because its really annoying..:

1. go to start menu.
2. click control panel.
3. click programs.
4. turn windows features on or off
5. wait until the list is loaded
6. search for Internet Information Services (IIS).
7. uncheck the box.
8. Wait until it's done with the changes.
9. restart computer, but then again the info box will tell you to do that anyways (you can leave this for later if you want to).

oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

If you are using java 1.8, remove XX:-UseSplitVerifier and use -noverify in your JVM properties.

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

for x in range(9):
    exec("string" + str(x) + " = 'hello'")

This should work.

This does money along with the commas

def format_money(money, presym='$', postsym=''):
    fmt = '%0.2f' % money
    dot = string.find(fmt, '.')
    ret = []
    if money < 0 :
        ret.append('(')
        p0 = 1
    else :
        p0 = 0
    ret.append(presym)
    p1 = (dot-p0) % 3 + p0
    while True :
        ret.append(fmt[p0:p1])
        if p1 == dot : break
        ret.append(',')
        p0 = p1
        p1 += 3
    ret.append(fmt[dot:])   # decimals
    ret.append(postsym)
    if money < 0 : ret.append(')')
    return ''.join(ret)

In this step I have Set the variable first:

<c:set var="structureId" value="<%=article.getStructureId()%>" scope="request"></c:set>

In this step I have checked the variable empty or not:

 <c:if test="${not empty structureId }">
    <a href="javascript:void(0);">Change Design</a>
 </c:if>

You need to use the Disposable Pattern like this:

private bool _disposed = false;

protected virtual void Dispose(bool disposing)
{
    if (!_disposed)
    {
        if (disposing)
        {
            // Dispose any managed objects
            // ...
        }

        // Now disposed of any unmanaged objects
        // ...

        _disposed = true;
    }
}

public void Dispose()
{
    Dispose(true);
    GC.SuppressFinalize(this);  
}

// Destructor
~YourClassName()
{
    Dispose(false);
}

Even better!

long tStart = System.nanoTime();
long tEnd = System.nanoTime();
long tRes = tEnd - tStart; // time in nanoseconds

Read the documentation about nanoTime()!

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

I think you should not consider any specific parser implementation. Java API for XML Processing lets you use any conforming parser implementation in a standard way. The code should be much more portable, and when you realise that a specific parser has grown too old, you can replace it with another without changing a line of your code (if you do it correctly).

Basically there are three ways of handling XML in a standard way:

• SAX This is the simplest API. You read the XML by defining a Handler class that receives the data inside elements/attributes when the XML gets processed in a serial way. It is faster and simpler if you only plan to read some attributes/elements and/or write some values back (your case).
• DOM This method creates an object tree which lets you modify/access it randomly so it is better for complex XML manipulation and handling.
• StAX This is in the middle of the path between SAX and DOM. You just write code to pull the data from the parser you are interested in when it is processed.

Forget about proprietary APIs such as JDOM or Apache ones (i.e. Apache Xerces XMLSerializer) because will tie you to a specific implementation that can evolve in time or lose backwards compatibility, which will make you change your code in the future when you want to upgrade to a new version of JDOM or whatever parser you use. If you stick to Java standard API (using factories and interfaces) your code will be much more modular and maintainable.

There is no need to say that all (I haven't checked all, but I'm almost sure) of the parsers proposed comply with a JAXP implementation so technically you can use all, no matter which.

In Scala, a List inherits from Seq, but implements Product; here is the proper definition of List :

sealed abstract class List[+A] extends AbstractSeq[A] with Product with ...

[Note: the actual definition is a tad bit more complex, in order to fit in with and make use of Scala's very powerful collection framework.]

Is there a reason you are not doing something like:

public class IPGUI extends JFrame implements ActionListener 
{
    private static JPanel contentPane;

    private JButton btnConvertDocuments;
    private JButton btnExtractImages;
    private JButton btnParseRIDValues;
    private JButton btnParseImageInfo;

    public IPGUI() 
    {
        ...

        btnConvertDocuments = new JButton("1. Convert Documents");

        ...

        btnExtractImages = new JButton("2. Extract Images");

        ...

        //etc.
    }

    public void actionPerformed(ActionEvent event) 
    {
        String command = event.getActionCommand();

        if (command.equals("w"))
        {
            FileConverter fc = new FileConverter();
            btnConvertDocuments.setEnabled( false );
        }
        else if (command.equals("x"))
        {
            ImageExtractor ie = new ImageExtractor();
            btnExtractImages.setEnabled( false );
        }

        // etc.
    }    
}

The if statement with your disabling code won't get called unless you keep calling the IPGUI constructor.

The most probable cause is that the content displaying over the popover has a higher z-index. Without the precise code/style, I can offer two options :

You should try pinpointing the exact elements with a web inspector (usually F12 on your favorite browser) and check their actual z-index.

If you find this value, you can set it lower than the popover which is z-index: 1010; by default

Or the other approach, not as good, would be to increase the z-index of the popover. You can do that either with the @zindexPopover in the Less files or directly by overriding

.popover {
    z-index: 1010; /* A value higher than 1010 that solves the problem */
}

If you can't find a solution, you should try reproducing the bug in something like this jsfiddle - you will probably resolve the problem while trying to get the bug.

I created a module to make dealing with trusted hosts slightly easier, psTrustedHosts. You can find the repo here on GitHub. It provides four functions that make working with trusted hosts easy: Add-TrustedHost, Clear-TrustedHost, Get-TrustedHost, and Remove-TrustedHost. You can install the module from PowerShell Gallery with the following command:

Install-Module psTrustedHosts -Force

In your example, if you wanted to append hosts 'machineC' and 'machineD' you would simply use the following command:

Add-TrustedHost 'machineC','machineD'

To be clear, this adds hosts 'machineC' and 'machineD' to any hosts that already exist, it does not overwrite existing hosts.

The Add-TrustedHost command supports pipeline processing as well (so does the Remove-TrustedHost command) so you could also do the following:

'machineC','machineD' | Add-TrustedHost

Inspired from Robert's answer, but when we use,

ng-click="searchAll = null" in the filter, it makes the model values as null and in-turn the search doesn't work with its normal functionality, so it would be better enough to use ng-click="searchAll = ''" instead

What that build error is telling you, that you have to either have an instance of Program or make Add static.

Simple example to achieve the below:

    ApplicationDbContext forumDB = new ApplicationDbContext();
    MonitorDbContext monitor = new MonitorDbContext();

Just scope the properties in the main context: (used to create and maintain the DB) Note: Just use protected: (Entity is not exposed here)

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("QAForum", throwIfV1Schema: false)
    {

    }
    protected DbSet<Diagnostic> Diagnostics { get; set; }
    public DbSet<Forum> Forums { get; set; }
    public DbSet<Post> Posts { get; set; }
    public DbSet<Thread> Threads { get; set; }
    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
    }
}

MonitorContext: Expose separate Entity here

public class MonitorDbContext: DbContext
{
    public MonitorDbContext()
        : base("QAForum")
    {

    }
    public DbSet<Diagnostic> Diagnostics { get; set; }
    // add more here
}

Diagnostics Model:

public class Diagnostic
{
    [Key]
    public Guid DiagnosticID { get; set; }
    public string ApplicationName { get; set; }
    public DateTime DiagnosticTime { get; set; }
    public string Data { get; set; }
}

If you like you could mark all entities as protected inside the main ApplicationDbContext, then create additional contexts as needed for each separation of schemas.

They all use the same connection string, however they use separate connections, so do not cross transactions and be aware of locking issues. Generally your designing separation so this shouldn't happen anyway.

Notice you're not dynamically allocating the variable, which pretty much means the data inside str, in your function, will be lost by the end of the function.

You should have:

char * createStr() {

    char char1= 'm';
    char char2= 'y';

    char *str = malloc(3);
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';

    return str;

}

Then, when you call the function, the type of the variable that will receive the data must match that of the function return. So, you should have:

char *returned_str = createStr();

It worths mentioning that the returned value must be freed to prevent memory leaks.

char *returned_str = createStr();

//doSomething
...

free(returned_str);

Recently, AWS added a feature called Sessions Manager to the Systems Manager service that allows one to SSH into an instance without needing to setup a private key or opening up port 22. I believe authentication is done with IAM and optionally MFA.

You can find out more about it here:

https://aws.amazon.com/blogs/aws/new-session-manager/

Declare found as "volatile". This should tell the compiler to NOT optimize it out.

volatile int found = 0;

In my case, I got a CAPTCHA error. If you get that, first logout/login to Bitbucket, Github, .... on the website and enter the required captcha.

After that, try again from intellij and it should prompt for another password.

As of July 2018 and the release of RxJS 6, the new way to get an Observable from a value is to import the of operator like so:

import { of } from 'rxjs';

and then create the observable from the value, like so:

of(someValue);

Note, that you used to have to do Observable.of(someValue) like in the currently accepted answer. There is a good article on the other RxJS 6 changes here.

You are looking for the __getitem__ method. See http://docs.python.org/reference/datamodel.html, section 3.4.6

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

this is a programatical approach:

 view.setVisibility(View.GONE); //For GONE
 view.setVisibility(View.INVISIBLE); //For INVISIBLE
 view.setVisibility(View.VISIBLE); //For VISIBLE

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

From the itertools recipes:

from itertools import tee

def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = tee(iterable)
    next(b, None)
    return zip(a, b)

for v, w in pairwise(a):
    ...

You can override OnFormClosing to do this. Just be careful you don't do anything too unexpected, as clicking the 'X' to close is a well understood behavior.

protected override void OnFormClosing(FormClosingEventArgs e)
{
    base.OnFormClosing(e);

    if (e.CloseReason == CloseReason.WindowsShutDown) return;

    // Confirm user wants to close
    switch (MessageBox.Show(this, "Are you sure you want to close?", "Closing", MessageBoxButtons.YesNo))
    {
    case DialogResult.No:
        e.Cancel = true;
        break;
    default:
        break;
    }        
}

In my opinion, the answer (presented above and repeated below):

NSString *model = [[UIDevice currentDevice] model];
if ([model isEqualToString:@"iPhone Simulator"]) {
    //device is simulator
}

is the best answer because it is obviously executed at RUNTIME versus being a COMPILE DIRECTIVE.

There is LIKE operator is added in Entity Framework Core 2.0:

var query = from e in _context.Employees
                    where EF.Functions.Like(e.Title, "%developer%")
                    select e;

Comparing to ... where e.Title.Contains("developer") ... it is really translated to SQL LIKE rather than CHARINDEX we see for Contains method.

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

You can add this declaration to silence the warnings.

declare var obj: any;

With user defined functions, you have to declare every parameter, even if they have a default value.

The following would execute successfully:

IF dbo.CheckIfSFExists( 23, default ) = 0
    SET @retValue = 'bla bla bla;

From ES6,

var co = require('co');
var $ = require('jQuery');

// because jquery doesn't support Promises/A+ spec
function ajax(opts) {
  return new Promise(function(resolve, reject) {
    $.extend(opts, {
      success: resolve,
      error: reject
    });
    $.ajax(opts);
  }
}

var poll = function() {
  co(function *() {
    return yield ajax({
      url: '/my-api',
      type: 'json',
      method: 'post'
    });
  }).then(function(response) {
    console.log(response);
  }).catch(function(err) {
    console.log(err);
  });
};

setInterval(poll, 5000);

• Doesn't use recursion (function stack is not affected).
• Doesn't suffer where setTimeout-recursion needs to be tail-call optimized.

Twitter Bootstrap assigns the active class to the li element that represents the active tab:

$("ul#sampleTabs li.active")

An alternative is to bind the shown event of each tab, and save the active tab:

var activeTab = null;
$('a[data-toggle="tab"]').on('shown', function (e) {
  activeTab = e.target;
})

this answer is late, but i think there is another way to do this in the context of anonymous handler class.

let's say:

class A {
    void foo() {
        obj.addHandler(new Handler() {
            void bar() {
                String className=A.this.getClass().getName();
                // ...
            }
        });
    }
}

it will achieve the same result. additionally, it's actually quite convenience since every class is defined at compile time, so no dynamicity is damaged.

above that, if the class is really nested, i.e. A actually is enclosed by B, the class of B can be easily known as:

B.this.getClass().getName()

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

=IF(X2>=85,0.559,IF(X2>=80,0.327,IF(X2>=75,0.255,-1)))

Explanation:

      0.559,                 'Use the appropriate number
      IF(X2>=80,             'Otherwise, if the number is in the next highest bracket
           0.327,            'Use the appropriate number
           IF(X2>=75,        'Otherwise, if the number is in the next highest bracket
              0.255,         'Use the appropriate number
              -1             'Otherwise, we're not in any of the ranges (Error)
             )
        )
   )

Exercise 16 from Zed Shaw's book? You can use escape characters as follows:

paragraph1 = "%s \n %s \n %s \n" % (line1, line2, line3)
target.write(paragraph1)
target.close()

This will strip all commas from the text and left justify it.

for row in inputfile:
    place = row['your_row_number_here'].strip(', ')

I've got the same exception and in my case the problem was in a renegotiation procecess. In fact my client closed a connection when the server tried to change a cipher suite. After digging it appears that in the jdk 1.6 update 22 renegotiation process is disabled by default. If your security constraints can effort this, try to enable the unsecure renegotiation by setting the sun.security.ssl.allowUnsafeRenegotiation system property to true. Here is some information about the process:

Session renegotiation is a mechanism within the SSL protocol that allows the client or the server to trigger a new SSL handshake during an ongoing SSL communication. Renegotiation was initially designed as a mechanism to increase the security of an ongoing SSL channel, by triggering the renewal of the crypto keys used to secure that channel. However, this security measure isn't needed with modern cryptographic algorithms. Additionally, renegotiation can be used by a server to request a client certificate (in order to perform client authentication) when the client tries to access specific, protected resources on the server.

Additionally there is the excellent post about this issue in details and written in (IMHO) understandable language.

Suppose you want to set a pop-up text box for clicking a button lets say bt whose id is button, then code using Toast will somewhat look like this:

Button bt;
bt = (Button) findViewById(R.id.button);
bt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {            
Toast.makeText(getApplicationContext(),"The text you want to display",Toast.LENGTH_LONG)
}

It's not consistent across vendors - Oracle, MySQL, and DB2 support dual:

SELECT 'Hello world'
  FROM DUAL

...while SQL Server, PostgreSQL, and SQLite don't require the FROM DUAL:

SELECT 'Hello world'

MySQL does support both ways.

Starting a service:

adb shell am startservice ...

start a Service. Options are: --user | current: Specify which user to run as; if not specified then run as the current user.

Stopping a service:

adb shell am stopservice ...

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

The solution is quite simple, it is all a matter of how you define things on the server / workstation in relation to your visual studio project.

First check the version of the Oracle library that you are using, in your case 2.111.7.20. Next go to the Windows GAC located in your windows home->assembly folder.

Scroll down to the Oracle dll, it is normally called Oracle.DataAccess or Oracle.Web. Find the right version of it and note down if it says x86 or AMD64.

In visual studio ensure that your target platform is the same as the dll in the GAC, so if it says x86 in the GAC folder ensure that the target platform is x64 and other x64. You can set this in Visual Studio project properties, under build/platform target.

Also ensure that your reference, under references in your project points to this exact same version on your development computer.

With this everything should work fine.

What I normally do is to check the server first as it is often easier in an enterprise environment to change the version of your local dependencies, then to ask a server administrator to do an installation of a different dll.

The same, Server.UrlEncode() calls HttpUtility.UrlEncode()

It is usually much faster to script out all the objects in the database, and create an empty one, that to delete from or truncate tables.

The following works perfectly:-

if(isset($_POST['signup'])){
$username=mysqli_real_escape_string($connect,$_POST['username']);
$email=mysqli_real_escape_string($connect,$_POST['email']);
$pass1=mysqli_real_escape_string($connect,$_POST['pass1']);
$pass2=mysqli_real_escape_string($connect,$_POST['pass2']);

Now, the $connect is my variable containing my connection to the database. You only left out the connection variable. Include it and it shall work perfectly.

From the Google Font Directory examples:

This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf

Here are some good sites:

• Good primer:

  http://www.alistapart.com/articles/cssatten

• Other Info:

  http://randsco.com/index.php/2009/07/04/p680

In your XML layout:

<Button
    android:id="@+id/cancelskill"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginLeft="25dp"
    android:layout_weight="1"
    android:background="@drawable/button_border"
    android:padding="10dp"
    android:text="Cancel"
    android:textAllCaps="false"
    android:textColor="#ffffff"
    android:textSize="20dp" />

In the drawable folder, create a file for the button's border style:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <stroke
        android:width="1dp"
        android:color="#f43f10" />
</shape>

And in your Activity:

    GradientDrawable gd1 = new GradientDrawable();
    gd1.setColor(0xFFF43F10); // Changes this drawbale to use a single color instead of a gradient
    gd1.setCornerRadius(5);
    gd1.setStroke(1, 0xFFF43F10);

    cancelskill.setBackgroundDrawable(gd1);

    cancelskill.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            cancelskill.setBackgroundColor(Color.parseColor("#ffffff"));
            cancelskill.setTextColor(Color.parseColor("#f43f10"));

            GradientDrawable gd = new GradientDrawable();

            gd.setColor(0xFFFFFFFF); // Changes this drawbale to use a single color instead of a gradient
            gd.setCornerRadius(5);
            gd.setStroke(1, 0xFFF43F10);
            cancelskill.setBackgroundDrawable(gd);

            finish();
        }
    });

If you have USB-Debugging/ADB enabled on your phone and your PC is authorized for debugging on your phone then you can try one of the follwing tools:

scrcpy

scrcpy connects over adb to your device and executes a temporary app to stream the contents of your screen to your PC and you're able to remote control your device. It works on GNU/Linux, Windows and macOS.

Vysor

Vysor is a chrome web app that connects to your device via adb and installs a companion app to stream your screen content to the PC. You can then remote control your device with your mouse.

MonkeyRemote

MonkeyRemote is a remote control tool written by myself before I found Vysor. It also connects through adb and lets you control your device by mouse but in contrast to Vysor, the streamed screen content updates very slow (~1 frame per second). The upside is that there is no need for a companion app to be installed.

There is nothing built into Java at the moment of writing this. I would suggest writing your own implementation. My preference is for a simple fluent builder interface instead of creating a map and passing it to function -- you end up with a nice contiguous chunk of code, for example:

String result = new TemplatedStringBuilder("My name is {{name}} and I from {{town}}")
   .replace("name", "John Doe")
   .replace("town", "Sydney")
   .finish();

Here is a simple implementation:

class TemplatedStringBuilder {

    private final static String TEMPLATE_START_TOKEN = "{{";
    private final static String TEMPLATE_CLOSE_TOKEN = "}}";

    private final String template;
    private final Map<String, String> parameters = new HashMap<>();

    public TemplatedStringBuilder(String template) {
        if (template == null) throw new NullPointerException();
        this.template = template;
    }

    public TemplatedStringBuilder replace(String key, String value){
        parameters.put(key, value);
        return this;
    }

    public String finish(){

        StringBuilder result = new StringBuilder();

        int startIndex = 0;

        while (startIndex < template.length()){

            int openIndex  = template.indexOf(TEMPLATE_START_TOKEN, startIndex);

            if (openIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            int closeIndex = template.indexOf(TEMPLATE_CLOSE_TOKEN, openIndex);

            if(closeIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            String key = template.substring(openIndex + TEMPLATE_START_TOKEN.length(), closeIndex);

            if (!parameters.containsKey(key)) throw new RuntimeException("missing value for key: " + key);

            result.append(template.substring(startIndex, openIndex));
            result.append(parameters.get(key));

            startIndex = closeIndex + TEMPLATE_CLOSE_TOKEN.length();
        }

        return result.toString();
    }
}

With async functions and promises, it now can work as simply as this:

async function foobar() {
  await $("#example").fadeOut().promise();
  doSomethingElse();
  await $("#example").fadeIn().promise();
}

Usinge the file argument in the print function, you can have different files per print:

print('Redirect output to file', file=open('/tmp/example.log', 'w'))

You can use lookups in Ansible in order to get the contents of a file, e.g.

user_data: "{{ lookup('file', user_data_file) }}"

Caveat: This lookup will work with local files, not remote files.

Here's a complete example from the docs:

- hosts: all
  vars:
     contents: "{{ lookup('file', '/etc/foo.txt') }}"
  tasks:
     - debug: msg="the value of foo.txt is {{ contents }}"

you can try this

pd.pandas.set_option('display.max_columns', None)

I suggest you to use provider. Provide is good when you want to configure it first before to use (against Service/Factory)

Something like:

.provider('Magazines', function() {

    this.url = '/';
    this.urlArray = '/';
    this.organId = 'Default';

    this.$get = function() {
        var url = this.url;
        var urlArray = this.urlArray;
        var organId = this.organId;

        return {
            invoke: function() {
                return ......
            }
        }
    };

    this.setUrl  = function(url) {
        this.url = url;
    };

   this.setUrlArray  = function(urlArray) {
        this.urlArray = urlArray;
    };

    this.setOrganId  = function(organId) {
        this.organId = organId;
    };
});

.config(function(MagazinesProvider){
    MagazinesProvider.setUrl('...');
    MagazinesProvider.setUrlArray('...');
    MagazinesProvider.setOrganId('...');
});

And now controller:

function MyCtrl($scope, Magazines) {        

        Magazines.invoke();

       ....

}

Negative numbers mean that you count from the right instead of the left. So, list[-1] refers to the last element, list[-2] is the second-last, and so on.

Swift 3, 4 & 5

Running code on the main thread

DispatchQueue.main.async {
    // Your code here
}

You can!!! In short use this as the connection string:

ldap://<host>:3268/DC=<my>,DC=<domain>?cn

together with your search filter, e.g.

(&(sAMAccountName={0})(&((objectCategory=person)(objectclass=user)(mail=*)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(memberOf:1.2.840.113556.1.4.1941:=CN=<some-special-nested-group>,OU=<ou3>,OU=<ou2>,OU=<ou1>,DC=<dc3>,DC=<dc2>,DC=<dc1>))))

That will search in the so called Global Catalog, that had been available out-of-the-box in our environment.

Instead of the known/common other versions (or combinations thereof) that did NOT work in our environment with multiple OUs:

ldap://<host>/DC=<my>,DC=<domain>
ldap://<host>:389/DC=<my>,DC=<domain>  (standard port)
ldap://<host>/OU=<someOU>,DC=<my>,DC=<domain>
ldap://<host>/CN=<someCN>,DC=<my>,DC=<domain>
ldap://<host>/(|(OU=<someOU1>)(OU=<someOU2>)),DC=<my>,DC=<domain> (search filters here shouldn't work at all by definition)

(I am a developer, not an AD/LDAP guru:) Damn I had been searching for this solution everywhere for almost 2 days and almost gave up, getting used to the thought I might have to implement this obviously very common scenario by hand (with Jasperserver/Spring security(/Tomcat)). (So this shall be a reminder if somebody else or me should have this problem again in the future :O) )

Here some other related threads I found during my research that had been mostly of little help:

• the solution hidden in a comment of LarreDo from 2006
• some Microsoft answered question of best practices how to design your organization in the directory, stating using multiple top-level OUs in bigger companies is not unusual or even suitable
• Tim Wong (2011) added that this may be a problem of unresolvable DNS names in the ForestDNSZones (part of the AD top-level domain used)
• example code for implementing it by hand when using Spring security (e.g. also used in Jasper)
• John Morrissey (2012) suggested it could be related to some security settings and it may work if you use TLS (I guess if the LDAP server wants to restrict such global searches for non-secure connections - which would not seem a good (its kind of half-baked) security approach to me)
• awatkins (2012) used some hacking approach in some mod_ldap.c code (of whatever software)

And here I will provide our anonymized Tomcat LDAP config in case it may be helpful (/var/lib/tomcat7/webapps/jasperserver/WEB-INF/applicationContext-externalAUTH-LDAP.xml):

• git add adds files to the Git index, which is a staging area for objects prepared to be commited.
• git commit commits the files in the index to the repository, git commit -a is a shortcut to add all the modified tracked files to the index first.
• git push sends all the pending changes to the remote repository to which your branch is mapped (eg. on GitHub).

In order to understand Git you would need to invest more effort than just glancing over the documentation, but it's definitely worth it. Just don't try to map Git commands directly to Subversion, as most of them don't have a direct counterpart.

Create a Java archive (.jar) file using NetBeans as follows:

1. Right-click on the Project name
2. Select Properties
3. Click Packaging
4. Check Build JAR after Compiling
5. Check Compress JAR File
6. Click OK to accept changes
7. Right-click on a Project name
8. Select Build or Clean and Build

Clean and Build will first delete build artifacts (such as .class files), whereas Build will retain any existing .class files, creating new versions necessary. To elucidate, imagine a project with two classes, A and B.

When built the first time, the IDE creates A.class and B.class. Now you delete B.java but don't clear out B.class. Executing Build should leave B.class in the build directory, and bundle it into the JAR. Selecting Clean and Build will delete B.class. Since B.java was deleted, no longer will B.class be bundled.

The JAR file is built. To view it inside NetBeans:

1. Click the Files tab
2. Expand Project name >> dist

Ensure files aren't being excluded when building the JAR file.

Most probably the file is just being cached by the server. You could either disable cache (but remember to enable it when the site goes live), or modify href of your link tag, so the server will not load it from cache.

If your page is created dynamically by some language like php, you could add some variable at the end of the href value, like:

    <link rel="stylesheet" type="text/css" href="css/yourStyles.css?<?php echo time(); ?>" />

That will add the current timestamp on the end of a file path, so it will always be unique and never loaded from cache.

If your page is static, you have to manage those variables yourself, so use something like:

    <link rel="stylesheet" type="text/css" href="css/yourStyles.css?version=1" />

after doing some changes in the file content, change version=1 to version=2 and so on.

If you wish to disable the cache from caching css files, refer to your server type documentation (it's done differently on apache, IIS, nginx etc.) or ask/search for a question on https://serverfault.com/

Assuming IIS - adding the key under with the right settings in the root or the relevant folder does the trick.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <caching enabled="false" enableKernelCache="false" /> <!-- This one -->
    </system.webServer>
</configuration>

That said sometimes one still has to recycle the Application Pool to "bump" the CSS. Therefore: Disabling IIS caching alone is not a 100% guaranteed solution.

For the browser: There are some notes on fine-grain controlling the local cache on FF over on SuperUser for the interested.

Instead of doing git checkout origin/master

just do git checkout master

then git branch will confirm your branch.

You don't need jQuery to do this. Here's an ES2015 solution:

// Get all input fields
const inputs = document.querySelectorAll('#register input');

// Get only the required ones
const requiredFields = Array.from(inputs).filter(input => input.required);

// Do your stuff with the required fields
requiredFields.forEach(field => /* do what you want */);

Or you could just use the :required selector:

Array.from(document.querySelectorAll('#register input:required'))
    .forEach(field => /* do what you want */);

It's perfectly possible to use both a color and an image as background for an element.

You set the background-color and background-image styles. If the image is smaller than the element, you need to use the background-position style to place it to the right, and to keep it from repeating and covering the entire background you use the background-repeat style:

background-color: green;
background-image: url(images/shadow.gif);
background-position: right;
background-repeat: no-repeat;

Or using the composite style background:

background: green url(images/shadow.gif) right no-repeat;

If you use the composite style background to set both separately, only the last one will be used, that's one possible reason why your color is not visible:

background: green; /* will be ignored */
background: url(images/shadow.gif) right no-repeat;

There is no way to specifically limit the background image to cover only part of the element, so you have to make sure that the image is smaller than the element, or that it has any transparent areas, for the background color to be visible.

Here is my working solution with search and clear icon for Angularjs\Bootstrap with CSS.

    <div class="form-group has-feedback has-clear">
                    <input type="search" class="form-control removeXicon" ng-model="filter" style="max-width:100%" placeholder="Search..." />
                    <div ng-switch on="!!filter">
                        <div ng-switch-when="false">
                            <span class="glyphicon glyphicon-search form-control-feedback"></span>
                        </div>
                        <div ng-switch-when="true">
                            <span class="glyphicon glyphicon-remove-sign form-control-feedback" ng-click="$parent.filter = ''" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></span>
                        </div>
                    </div>                        
                </div>

------

CSS

/* hide the built-in IE10+ clear field icon */
.removeXicon::-ms-clear {
  display: none;
}

/* hide the built-in chrome clear field icon */
.removeXicon::-webkit-search-decoration,
.removeXicon::-webkit-search-cancel-button,

malloc will do.

 int rows = 20;
 int cols = 20;
 int *array;

  array = malloc(rows * cols * sizeof(int));

Refer the below article for help:-

Note that dnx has a different cache for feeding HTTP results:

Microsoft .NET Development Utility Clr-x86-1.0.0-rc1-16231
   CACHE https://www.nuget.org/api/v2/
   CACHE http://192.168.148.21/api/odata/

Which you can clear with

dnu clear-http-cache

Now we just need to find out what the command will be on the new dotnet CLI tool.

...and here it is:

dotnet restore --no-cache

Don't use sprintf.
It will overflow your String-Buffer and crash your Program.

Use os.walk to iterate recursively over directory content:

import os

root_dir = '.'

for directory, subdirectories, files in os.walk(root_dir):
    for file in files:
        print os.path.join(directory, file)

No real difference between os.system and subprocess.call here - unless you have to deal with strangely named files (filenames including spaces, quotation marks and so on). If this is the case, subprocess.call is definitely better, because you don't need to do any shell-quoting on file names. os.system is better when you need to accept any valid shell command, e.g. received from user in the configuration file.

you can use this script

# git mv a folder and sub folders in windows 

function Move-GitFolder {
    param (
        $target,
        $destination
    )
    
    Get-ChildItem $target -recurse |
    Where-Object { ! $_.PSIsContainer } |
    ForEach-Object { 
        $fullTargetFolder = [System.IO.Path]::GetFullPath((Join-Path (Get-Location) $target))
        $fullDestinationFolder = [System.IO.Path]::GetFullPath((Join-Path (Get-Location) $destination))
        $fileDestination = $_.Directory.FullName.Replace($fullTargetFolder.TrimEnd('\'), $fullDestinationFolder.TrimEnd('\'))

        New-Item -ItemType Directory -Force -Path $fileDestination | Out-Null

        $filePath = Join-Path $fileDestination $_.Name

        git mv $_.FullName $filePath
        
    }
}

Usage

Move-GitFolder <Target folder> <Destination folder>

the advantage of this solution over other solutions is that it move folders and files recursively in a folder and even create the folder structure if it doesn't exist

A solution could be to use a local file which retrieves the remote content

remoteInclude.php

<?php
$url = $_GET['url'];
$contents = file_get_contents($url);
echo $contents;

The HTML

<iframe frameborder="1" id="frametest" src="/remoteInclude.php?url=REMOTE_URL_HERE"></iframe>
<script>
    $("#frametest").load(function (){       
    var contents =$("#frametest").contents();
});

About hyperlinks:

The main use of anchor tags - <a></a> - is as hyperlinks. That basically means that they take you somewhere. Hyperlinks require the href property, because it specifies a location.

Hash:

A hash - # within a hyperlink specifies an html element id to which the window should be scrolled.

href="#some-id" would scroll to an element on the current page such as <div id="some-id">.

href="//site.com/#some-id" would go to site.com and scroll to the id on that page.

Scroll to Top:

href="#" doesn't specify an id name, but does have a corresponding location - the top of the page. Clicking an anchor with href="#" will move the scroll position to the top.

See this demo.

This is the expected behavior according to the w3 documentation.

Hyperlink placeholders:

An example where a hyperlink placeholder makes sense is within template previews. On single page demos for templates, I have often seen <a href="#"> so that the anchor tag is a hyperlink, but doesn't go anywhere. Why not leave the href property blank? A blank href property is actually a hyperlink to the current page. In other words, it will cause a page refresh. As I discussed, href="#" is also a hyperlink, and causes scrolling. Therefore, the best solution for hyperlink placeholders is actually href="#!" The idea here is that there hopefully isn't an element on the page with id="!" (who does that!?) and the hyperlink therefore refers to nothing - so nothing happens.

About anchor tags:

Another question that you may be wondering is, "Why not just leave the href property off?". A common response I've heard is that the href property is required, so it "should" be present on anchors. This is FALSE! The href property is required only for an anchor to actually be a hyperlink! Read this from w3. So, why not just leave it off for placeholders? Browsers render default styles for elements and will change the default style of an anchor tag that doesn't have the href property. Instead, it will be considered like regular text. It even changes the browser's behavior regarding the element. The status bar (bottom of the screen) will not be displayed when hovering on an anchor without the href property. It is best to use a placeholder href value on an anchor to ensure it is treated as a hyperlink.

See this demo demonstrating style and behavior differences.

Using

<a href="foo.html"><div class="xyz"></div></a>

works in browsers, even though it violates current HTML specifications. It is permitted according to HTML5 drafts.

When you say that it does not work, you should explain exactly what you did (including jsfiddle code is a good idea), what you expected, and how the behavior different from your expectations.

It is unclear what you mean by “all the content in that div is in the css”, but I suppose it means that the content is really empty in HTML markup and you have CSS like

.xyz:before { content: "Hello world"; }

The entire block is then clickable, with the content text looking like link text there. Isn’t this what you expected?

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

Starting from PHP 5.6, you can use the ARRAY_FILTER_USE_KEY flag in array_filter:

$result = array_filter($my_array, function ($k) use ($allowed) {
    return in_array($k, $allowed);
}, ARRAY_FILTER_USE_KEY);

Otherwise, you can use this function (from TestDummy):

function filter_array_keys(array $array, $callback)
{
    $matchedKeys = array_filter(array_keys($array), $callback);

    return array_intersect_key($array, array_flip($matchedKeys));
}

$result = filter_array_keys($my_array, function ($k) use ($allowed) {
    return in_array($k, $allowed);
});

And here is an augmented version of mine, which accepts a callback or directly the keys:

function filter_array_keys(array $array, $keys)
{
    if (is_callable($keys)) {
        $keys = array_filter(array_keys($array), $keys);
    }

    return array_intersect_key($array, array_flip($keys));
}

// using a callback, like array_filter:
$result = filter_array_keys($my_array, function ($k) use ($allowed) {
    return in_array($k, $allowed);
});

// or, if you already have the keys:
$result = filter_array_keys($my_array, $allowed));

Last but not least, you may also use a simple foreach:

$result = [];
foreach ($my_array as $key => $value) {
    if (in_array($key, $allowed)) {
        $result[$key] = $value;
    }
}

I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.

Here is a very contrived example:

IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));

Here is the extension method:

public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
    return obj == null ? new List<T>() : obj.ToList();
}

TL;DR

You can do this by using the --prefix flag and the --global* flag.

pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules
[email protected] /Users/pje/foo/vendor/node_modules/bower

*Even though this is a "global" installation, installed bins won't be accessible through the command line unless ~/foo/vendor/node_modules exists in PATH.

TL;DR

Every configurable attribute of npm can be set in any of six different places. In order of priority:

• Command-Line Flags: --prefix ./vendor/node_modules
• Environment Variables: NPM_CONFIG_PREFIX=./vendor/node_modules
• User Config File: $HOME/.npmrc or userconfig param
• Global Config File: $PREFIX/etc/npmrc or userconfig param
• Built-In Config File: path/to/npm/itself/npmrc
• Default Config: node_modules/npmconf/config-defs.js

By default, locally-installed packages go into ./node_modules. global ones go into the prefix config variable (/usr/local by default).

You can run npm config list to see your current config and npm config edit to change it.

PS

In general, npm's documentation is really helpful. The folders section is a good structural overview of npm and the config section answers this question.

Documentation of the change

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

Solution #1: Your statement

.Range(Cells(RangeStartRow, RangeStartColumn), Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does not refer to a proper Range to act upon. Instead,

.Range(.Cells(RangeStartRow, RangeStartColumn), .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does (and similarly in some other cases).

Solution #2: Activate Worksheets("Cable Cards") prior to using its cells.

Explanation: Cells(RangeStartRow, RangeStartColumn) (e.g.) gives you a Range, that would be ok, and that is why you often see Cells used in this way. But since it is not applied to a specific object, it applies to the ActiveSheet. Thus, your code attempts using .Range(rng1, rng2), where .Range is a method of one Worksheet object and rng1 and rng2 are in a different Worksheet.

There are two checks that you can do to make this quite evident:

1. Activate your Worksheets("Cable Cards") prior to executing your Sub and it will start working (now you have well-formed references to Ranges). For the code you posted, adding .Activate right after With... would indeed be a solution, although you might have a similar problem somewhere else in your code when referring to a Range in another Worksheet.

2. With a sheet other than Worksheets("Cable Cards") active, set a breakpoint at the line throwing the error, start your Sub, and when execution breaks, write at the immediate window

   Debug.Print Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   Debug.Print .Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   and see the different outcomes.

Conclusion: Using Cells or Range without a specified object (e.g., Worksheet, or Range) might be dangerous, especially when working with more than one Sheet, unless one is quite sure about what Sheet is active.

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

Section 4.10.22.2 Implicit submission of the W3C HTML5 spec says:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Note: Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

Therefore, a standards-compliant way to disable any implicit submission of the form is to place a disabled submit button as the first submit button in the form:

<form action="...">
  <!-- Prevent implicit submission of the form -->
  <button type="submit" disabled style="display: none" aria-hidden="true"></button>

  <!-- ... -->

  <button type="submit">Submit</button>
</form>

One nice feature of this approach is that it works without JavaScript; whether or not JavaScript is enabled, a standards-conforming web browser is required to prevent implicit form submission.

For narrowing the type of the property, simple extend works perfect, as in Nitzan's answer:

interface A {
    x: string | number;
}

interface B extends A {
    x: number;
}

For widening, or generally overriding the type, you can do Zskycat's solution:

interface A {
    x: string
}

export type B = Omit<A, 'x'> & { x: number };

But, if your interface A is extending a general interface, you will lose the custom types of A's remaining properties when using Omit.

e.g.

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = Omit<A, 'x'> & { x: number };

let b: B = { x: 2, y: "hi" }; // no error on b.y! 

The reason is, Omit internally only goes over Exclude<keyof A, 'x'> keys which will be the general string | number in our case. So, B would become {x: number; } and accepts any extra property with the type of number | string | boolean.

To fix that, I came up with a different OverrideProps utility type as following:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

Example:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = OverrideProps<A, { x: number }>;

let b: B = { x: 2, y: "hi" }; // error: b.y should be boolean!

This is fastest way I know of, even though you said you didn't want to use regular expressions:

Regex.Replace(XML, @"\s+", "")

This is similar to the difference between

SELECT * FROM table_name and SELECT 1 FROM table_name.  

If you do

SELECT 1 FROM table_name

it will give you the number 1 for each row in the table. So yes count(*) and count(1) will provide the same results as will count(8) or count(column_name)

If you are using maven, adding below dependency should work

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0</version>
</dependency>

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

This is not the exact answer to this question, but those who are not able to find setting popup. Their is two ways to open setting pop up.

Here is the function which help you

private void saveBitmap(Bitmap bitmap,String path){
        if(bitmap!=null){
            try {
                FileOutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(path); //here is set your file path where you want to save or also here you can set file object directly

                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream); // bitmap is your Bitmap instance, if you want to compress it you can compress reduce percentage
                    // PNG is a lossless format, the compression factor (100) is ignored
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    try {
                        if (outputStream != null) {
                            outputStream.close();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }    
        }
    }

JavaScript syntax 101. Here is a function declaration:

function foo() {}

Note that there's no semicolon: this is just a function declaration. You would need an invocation, foo(), to actually run the function.

Now, when we add the seemingly innocuous exclamation mark: !function foo() {} it turns it into an expression. It is now a function expression.

The ! alone doesn't invoke the function, of course, but we can now put () at the end: !function foo() {}() which has higher precedence than ! and instantly calls the function.

So what the author is doing is saving a byte per function expression; a more readable way of writing it would be this:

(function(){})();

Lastly, ! makes the expression return true. This is because by default all immediately invoked function expressions (IIFE) return undefined, which leaves us with !undefined which is true. Not particularly useful.

try this code below :

var currentLocation = document.location;
muzLoc = String(currentLocation).substring(0,45);
prodLoc = String(currentLocation).substring(0,48); 
techLoc = String(currentLocation).substring(0,47);

You also need to handle exceptions from threads:

static void Main(string[] args) {
Application.ThreadException += MYThreadHandler;
}

private void MYThreadHandler(object sender, Threading.ThreadExceptionEventArgs e)
{
    Console.WriteLine(e.Exception.StackTrace);
}

Whoop, sorry that was for winforms, for any threads you're using in a console application you will have to enclose in a try/catch block. Background threads that encounter unhandled exceptions do not cause the application to end.

From MSDN:

Date and time data from January 1, 1753, to December 31, 9999, with an accuracy of one three-hundredth second, or 3.33 milliseconds. Values are rounded to increments of .000, .003, or .007 milliseconds. Stored as two 4-byte integers. The first 4 bytes store the number of days before or after the base date, January 1, 1900. The base date is the system's reference date. Values for datetime earlier than January 1, 1753, are not permitted. The other 4 bytes store the time of day represented as the number of milliseconds after midnight. Seconds have a valid range of 0–59.

SQL uses a different system than C# for DateTime values.

You can use your MinValue as a sentinel value - and if it is MinValue - pass null into your object (and store the date as nullable in the DB).

if(date == dateTime.Minvalue)
    objinfo.BirthDate = null;

ArrayUtils.indexOf(array, value);
Ints.indexOf(array, value);
Arrays.asList(array).indexOf(value);

In my case, all warn disappeared after I directly changed swift version from 2.x to 4.0 in build settings except two warn.

These warning related to myprojectnameTests and myprojectnameUITests folder. I didn't notice and I thought its relate to direct immigration from Xcode 7 to Xcode 9 and I thought I couldn't solve this problem and I should install missed Xcode 8 version.

In my case, I deleted these folders and all warns disappeared, but you can recreate this folder and contains using this:

file > new > target > (uitest or unittest extensions)

and use this article for create test cases: https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/04-writing_tests.html

hey all...i had a similar problem with my cms system. i needed a hard path for some security aspects. think the best way is like rob wrote. for quick an dirty coding think this works also..:-)

<?php
$path   = getcwd(); 
$myfile = "/test.inc.php";

/* 

getcwd () points to: /usr/srv/apache/htdocs/myworkingdir (as example)

echo ($path.$myfile);
would return...

/usr/srv/apache/htdocs/myworkingdir/test.inc.php

access outside your working directory is not allowed.
*/


includ_once ($path.$myfile);

//some code

If you are using the emulator, you may try the following. The below worked for me. Go to Tools --> AVD Manager --> (Pick Your emulator) --> Wipe Data. The error went away.

It’s just HTML with Server Side Includes.

the code behind for the window:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase

    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand

        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

If you have to install an older version of a package, just specify it

npm install <package>@<version>

For example: npm install [email protected]

You can also add the --save flag to that command to add it to your package.json dependencies, or --save --save-exact flags if you want that exact version specified in your package.json dependencies.

The install command is documented here: https://docs.npmjs.com/cli/install

If you're not sure what versions of a package are available, you can use:

npm view <package> versions

And npm view can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view

I have looked around for a fix for this. I have a jquery mobile site that has a final print page and it combines dozens of pages. I tried all the fixes above but the only thing I could get to work is this:

<div style="clear:both!important;"/></div>
<div style="page-break-after:always"></div> 
<div style="clear:both!important;"/> </div>

Just using the Array iteration methods built into JS is fine for this:

var result1 = [_x000D_
    {id:1, name:'Sandra', type:'user', username:'sandra'},_x000D_
    {id:2, name:'John', type:'admin', username:'johnny2'},_x000D_
    {id:3, name:'Peter', type:'user', username:'pete'},_x000D_
    {id:4, name:'Bobby', type:'user', username:'be_bob'}_x000D_
];_x000D_
_x000D_
var result2 = [_x000D_
    {id:2, name:'John', email:'[email protected]'},_x000D_
    {id:4, name:'Bobby', email:'[email protected]'}_x000D_
];_x000D_
_x000D_
var props = ['id', 'name'];_x000D_
_x000D_
var result = result1.filter(function(o1){_x000D_
    // filter out (!) items in result2_x000D_
    return !result2.some(function(o2){_x000D_
        return o1.id === o2.id;          // assumes unique id_x000D_
    });_x000D_
}).map(function(o){_x000D_
    // use reduce to make objects with only the required properties_x000D_
    // and map to apply this to the filtered array as a whole_x000D_
    return props.reduce(function(newo, name){_x000D_
        newo[name] = o[name];_x000D_
        return newo;_x000D_
    }, {});_x000D_
});_x000D_
_x000D_
document.body.innerHTML = '<pre>' + JSON.stringify(result, null, 4) +_x000D_
        '</pre>';

If you are doing this a lot, then by all means look at external libraries to help you out, but it's worth learning the basics first, and the basics will serve you well here.

If you need different column width, do this:

<tr>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
</tr>
<tr>
    <td colspan="9">
        <table>
            <tr>
                <td></td>
                <td></td>
                <td></td>
                <td></td>
            </tr>
        </table>

Yattag http://www.yattag.org/ or https://github.com/leforestier/yattag provides an interesting API to create such XML document (and also HTML documents).

It's using context manager and with keyword.

from yattag import Doc, indent

doc, tag, text = Doc().tagtext()

with tag('root'):
    with tag('doc'):
        with tag('field1', name='blah'):
            text('some value1')
        with tag('field2', name='asdfasd'):
            text('some value2')

result = indent(
    doc.getvalue(),
    indentation = ' '*4,
    newline = '\r\n'
)

print(result)

so you will get:

<root>
    <doc>
        <field1 name="blah">some value1</field1>
        <field2 name="asdfasd">some value2</field2>
    </doc>
</root>

I usually add separate safe pipe reusable component as following

# Add Safe Pipe

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

@Pipe({name: 'mySafe'})
export class SafePipe implements PipeTransform {
    constructor(private sanitizer: DomSanitizer) {
    }

    public transform(url) {
        return this.sanitizer.bypassSecurityTrustResourceUrl(url);
    }
}

# then create shared pipe module as following 

import { NgModule } from '@angular/core'; 
import { SafePipe } from './safe.pipe';
@NgModule({
    declarations: [
        SafePipe
    ],
    exports: [
        SafePipe
    ]
})
export class SharedPipesModule {
}

# import shared pipe module in your native module

@NgModule({
    declarations: [],
    imports: [
        SharedPipesModule,
    ],
})
export class SupportModule {
}

<!-------------------
call your url (`trustedUrl` for me) and add `mySafe` as defined in Safe Pipe
---------------->
<div class="container-fluid" *ngIf="trustedUrl">
    <iframe [src]="trustedUrl | mySafe" align="middle" width="100%" height="800" frameborder="0"></iframe>
</div>

You can try the cases env in amsmath.

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation}
  f(x)=\begin{cases}
    1, & \text{if $x<0$}.\\
    0, & \text{otherwise}.
  \end{cases}
\end{equation}

\end{document}

Get the path of running Apache

$ ps -ef | grep apache
apache   12846 14590  0 Oct20 ?        00:00:00 /usr/sbin/apache2

Append -V argument to the path

$ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"

Reference:

The second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index). Of course, this form of query is only available if the column is in a full text index. If it isn't, then only the first form is available.

The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.

The CONTAINS query should be:

SELECT * FROM table WHERE CONTAINS(Column, 'test');

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

struct date
{
    int month;
    int day;
    int year;
};

int calcN(struct date d)
{
    int N;
    int f(struct date d);
    int g(int m);

    N = 1461 * f(d) / 4 + 153 * g(d.month) / 5 + d.day;

    if(d.year < 1700 || (d.year == 1700 && d.month < 3))
    {
        printf("Date must be after February 29th, 1700\n");

        return 0;
    }
    else if(d.year < 1800 || (d.year == 1800 && d.month < 3))
        N += 2;
    else if(d.year < 1900 || (d.year == 1900 && d.month < 3))
        N += 1;    

    return N;
}

int f(struct date d)
{
    if(d.month <= 2)
        d.year -= 1;

    return d.year;
}

int g(int m)
{
    if(m <=2)
        m += 13;
    else
        m += 1;
    
    return m;
}

int main(void)
{
    int calcN(struct date d);
    struct date d1, d2;
    int N1, N2;
    time_t t;

    time(&t);
    struct tm *now = localtime(&t);


    d1.month = now->tm_mon + 1;
    d1.day = now->tm_mday;
    d1.year = now->tm_year + 1900;

    printf("Today's date: %02i/%02i/%i\n", d1.month, d1.day, d1.year);

    N1 = calcN(d1);

    printf("Enter birthday (mm dd yyyy): ");
    scanf("%i%i%i", &d2.month, &d2.day, &d2.year);

    N2 = calcN(d2);

    if(N2 == 0)
        return 0;

    printf("Number of days since birthday: %i\n", N1 - N2);

    return 0;
}

Just add this function and call it, it will convert List to DataTable.

public static DataTable ToDataTable<T>(List<T> items)
{
        DataTable dataTable = new DataTable(typeof(T).Name);

        //Get all the properties
        PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        foreach (PropertyInfo prop in Props)
        {
            //Defining type of data column gives proper data table 
            var type = (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) ? Nullable.GetUnderlyingType(prop.PropertyType) : prop.PropertyType);
            //Setting column names as Property names
            dataTable.Columns.Add(prop.Name, type);
        }
        foreach (T item in items)
        {
           var values = new object[Props.Length];
           for (int i = 0; i < Props.Length; i++)
           {
                //inserting property values to datatable rows
                values[i] = Props[i].GetValue(item, null);
           }
           dataTable.Rows.Add(values);
      }
      //put a breakpoint here and check datatable
      return dataTable;
}

getline() is what you're looking for. You use strings in C++, and you don't need to know the size ahead of time.

Assuming std namespace:

 ifstream file1("myfile.txt");
 string stuff;

 while (getline(file1, stuff, '\n')) {
      cout << stuff << endl;
 }

 file1.close();

In case others have the same problem, I ran into this error after updating a project to 4.7. Oddly enough, I had to remove the System.ValueTuple reference for this error to go away.

Static fields are initialized when the class is loaded by the class loader. Default values are assigned at this time. This is done in the order than they appear in the source code.

Here's a general solution:

def get_text_excluding_children(driver, element):
    return driver.execute_script("""
    return jQuery(arguments[0]).contents().filter(function() {
        return this.nodeType == Node.TEXT_NODE;
    }).text();
    """, element)

The element passed to the function can be something obtained from the find_element...() methods (i.e. it can be a WebElement object).

Or if you don't have jQuery or don't want to use it you can replace the body of the function above above with this:

return self.driver.execute_script("""
var parent = arguments[0];
var child = parent.firstChild;
var ret = "";
while(child) {
    if (child.nodeType === Node.TEXT_NODE)
        ret += child.textContent;
    child = child.nextSibling;
}
return ret;
""", element) 

I'm actually using this code in a test suite.

I am amazed how I've not been able to find a clear example of how to authenticate an user right from the login screen down to using the Authorize attribute over my ApiController methods after several hours of Googling.

That's because you are getting confused about these two concepts:

• Authentication is the mechanism whereby systems may securely identify their users. Authentication systems provide an answers to the questions:

  • Who is the user?
  • Is the user really who he/she represents himself to be?

• Authorization is the mechanism by which a system determines what level of access a particular authenticated user should have to secured resources controlled by the system. For example, a database management system might be designed so as to provide certain specified individuals with the ability to retrieve information from a database but not the ability to change data stored in the datbase, while giving other individuals the ability to change data. Authorization systems provide answers to the questions:

  • Is user X authorized to access resource R?
  • Is user X authorized to perform operation P?
  • Is user X authorized to perform operation P on resource R?

The Authorize attribute in MVC is used to apply access rules, for example:

 [System.Web.Http.Authorize(Roles = "Admin, Super User")]
 public ActionResult AdministratorsOnly()
 {
     return View();
 }

The above rule will allow only users in the Admin and Super User roles to access the method

These rules can also be set in the web.config file, using the location element. Example:

  <location path="Home/AdministratorsOnly">
    <system.web>
      <authorization>
        <allow roles="Administrators"/>
        <deny users="*"/>
      </authorization>
    </system.web>
  </location>

However, before those authorization rules are executed, you have to be authenticated to the current web site.

Even though these explain how to handle unauthorized requests, these do not demonstrate clearly something like a LoginController or something like that to ask for user credentials and validate them.

From here, we could split the problem in two:

• Authenticate users when consuming the Web API services within the same Web application

  This would be the simplest approach, because you would rely on the Authentication in ASP.Net

  This is a simple example:

  Web.config

  <authentication mode="Forms">
    <forms
      protection="All"
      slidingExpiration="true"
      loginUrl="account/login"
      cookieless="UseCookies"
      enableCrossAppRedirects="false"
      name="cookieName"
    />
  </authentication>
  

  Users will be redirected to the account/login route, there you would render custom controls to ask for user credentials and then you would set the authentication cookie using:

      if (ModelState.IsValid)
      {
          if (Membership.ValidateUser(model.UserName, model.Password))
          {
              FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
              return RedirectToAction("Index", "Home");
          }
          else
          {
              ModelState.AddModelError("", "The user name or password provided is incorrect.");
          }
      }
  
      // If we got this far, something failed, redisplay form
      return View(model);
  

• Cross - platform authentication

  This case would be when you are only exposing Web API services within the Web application therefore, you would have another client consuming the services, the client could be another Web application or any .Net application (Win Forms, WPF, console, Windows service, etc)

  For example assume that you will be consuming the Web API service from another web application on the same network domain (within an intranet), in this case you could rely on the Windows authentication provided by ASP.Net.

  <authentication mode="Windows" />
  

  If your services are exposed on the Internet, then you would need to pass the authenticated tokens to each Web API service.

  For more info, take a loot to the following articles:

Thanks a ton for Bhaskar Karambelkar's answer which explains in detail and fixed my issue. But also I would like to re phrase the answer in three simple steps for someone who is in a hurry to fix

1. Make your wsdl local location reference as wsdlLocation= "http://localhost/wsdl/yourwsdlname.wsdl"
2. Create a META-INF folder right under the src. Put your wsdl file/s in a folder under META-INF, say META-INF/wsdl

3. Create an xml file jax-ws-catalog.xml under META-INF as below

   <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system"> <system systemId="http://localhost/wsdl/yourwsdlname.wsdl" uri="wsdl/yourwsdlname.wsdl" /> </catalog>

Now package your jar. No more reference to the local directory, it's all packaged and referenced within

Use git clone with the --depth option set to 1 to create a shallow clone with a history truncated to the latest commit.

For example:

git clone --depth 1 https://github.com/user/repo.git

To also initialize and update any nested submodules, also pass --recurse-submodules and to clone them shallowly, also pass --shallow-submodules.

For example:

git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git

While the existing answers have given solutions to solve the issue and the second half of the question, they do not provide an answer to the self discovery aspect of the first half of the question that is in bold:

"How can I see which variable causes memory overhead...?"

It may not have been as robust 3 years ago, but the Chrome Developer Tools "Profiles" section is now quite powerful and feature rich. The Chrome team has an insightful article on using it and thus also how garbage collection (GC) works in javascript, which is at the core of this question.

Since delete is basically the root of the currently accepted answer by Yochai Akoka, it's important to remember what delete does. It's irrelevant if not combined with the concepts of how GC works in the next two answers: if there's an existing reference to an object it's not cleaned up. The answers are more correct, but probably not as appreciated because they require more thought than just writing 'delete'. Yes, one possible solution may be to use delete, but it won't matter if there's another reference to the memory leak.

Another answer appropriately mentions circular references and the Chrome team documentation can provide much more clarity as well as the tools to verify the cause.

Since delete was mentioned here, it also may be useful to provide the resource Understanding Delete. Although it does not get into any of the actual solution which is really related to javascript's garbage collector.

in your question, both buffer and byteArray seem to be byte[]. So:

ImageElement image = ImageElement.FromBinary(buffer);

Add the following dependencies

<dependency>
    <groupId>org.codehaus.jackson</groupId> 
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.7</version>
</dependency>

<dependency>
    <groupId>org.codehaus.jackson</groupId> 
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.7</version>
</dependency>

Modify request as follows

$.ajax({ 
    url:urlName,    
    type:"POST", 
    contentType: "application/json; charset=utf-8",
    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser          
    processData:false, //To avoid making query String instead of JSON
    success: function(resposeJsonObject){
        // Success Message Handler
    }
});

Controller side

@RequestMapping(value = urlPattern , method = RequestMethod.POST)
public @ResponseBody Person save(@RequestBody Person jsonString) {

   Person person=personService.savedata(jsonString);
   return person;
}

@RequestBody - Covert Json object to java
@ResponseBody- convert Java object to json

$arr = array(1, 'a', 3, 4 => 1, 'b' => 1);
foreach ($arr as $key => $val) {
    echo "{$key} = {$val}" . (end(array_keys($arr))===$key ? '' : ', ');
}
// output: 0 = 1, 1 = a, 2 = 3, 4 = 1, b = 1

Adding my two cents for those searching for "Ensure that the org.eclipse.core.runtime bundle is resolved and started":

Adding "arbitrary" bundles to the list of bundles just because it seems that they are missing is not always the best solution. Sometimes it can get quite frustrating, because those new plugins might depend on other missing bundles, which need even more bundles and so on...

So, before adding a new dependency to the list of required bundles, make sure you understand why the bundle is needed (the debugger is your friend!).

This question here doesn't provide enough information to make this a valid answer in all cases, but if you encounter the message that the org.eclipse.core.runtime is missing, try setting the eclipse.application.launchDefault system property to false, especially if you try to run an application which is not an "eclipse application" (but maybe just a headless runtime on top of equinox).

This link might come in handy: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html, look for the eclipse.application.launchDefault system property.

Recursive traverse object or array with array or objects elements:

function traverse(&$objOrArray)
{
    foreach ($objOrArray as $key => &$value)
    {
        if (is_array($value) || is_object($value))
        {
            traverse($value);
        }
        else
        {
            // DO SOMETHING
        }
    }
}

'SELECT * FROM Employ where number = ' + parseInt(val, 10) + ';'

For example, if val is "10" then this will end up building the string:

"SELECT * FROM Employ where number = 10;"

Another way to do it:

MEDIA_ROOT = '/home/USER/Projects/REPO/src/PROJECT/APP/static/media/'
MEDIA_URL = '/static/media/'

This would require you to move your media folder to a sub directory of a static folder.

Then in your template you can use:

<img class="scale-with-grid" src="{{object.photo.url}}"/>

I found this worked in my scenario.

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

$.get("urlToCheck.com").done(function () {
  alert("success");
}).fail(function () {
   alert("failed.");
});

Honestly, I feel more comfortable with Alfred blog definitions:

Object: real world objects shares 2 main characteristics, state and behavior. Human have state (name, age) and behavior (running, sleeping). Car have state (current speed, current gear) and behavior (applying brake, changing gear). Software objects are conceptually similar to real-world objects: they too consist of state and related behavior. An object stores its state in fields and exposes its behavior through methods.

Class: is a “template” / “blueprint” that is used to create objects. Basically, a class will consists of field, static field, method, static method and constructor. Field is used to hold the state of the class (eg: name of Student object). Method is used to represent the behavior of the class (eg: how a Student object going to stand-up). Constructor is used to create a new Instance of the Class.

Instance: An instance is a unique copy of a Class that representing an Object. When a new instance of a class is created, the JVM will allocate a room of memory for that class instance.

Given the next example:

public class Person {
    private int id;
    private String name;
    private int age;

    public Person (int id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + id;
        return result;
    }

    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Person other = (Person) obj;
        if (id != other.id)
            return false;
        return true;
    }

    public static void main(String[] args) {
        //case 1
        Person p1 = new Person(1, "Carlos", 20);
        Person p2 = new Person(1, "Carlos", 20);

        //case 2
        Person p3 = new Person(2, "John", 15);
        Person p4 = new Person(3, "Mary", 17);
    }
}

For case 1, there are two instances of the class Person, but both instances represent the same object.

For case 2, there are two instances of the class Person, but each instance represent a different object.

So class, object and instance are different things. Object and instance are not synonyms as is suggested in the answer selected as right answer.

To create elements with equal width using Flex, you should set to your's child (flex elements):

flex-basis: 25%;
flex-grow: 0;

It will give to all elements in row 25% width. They will not grow and go one by one.

Oracle 10g has functions that allow the use of POSIX-compliant regular expressions in SQL:

• REGEXP_LIKE
• REGEXP_REPLACE
• REGEXP_INSTR
• REGEXP_SUBSTR

See the Oracle Database SQL Reference for syntax details on this functions.

Take a look at Regular expressions in Perl with examples.

Code :

    select * from tbl where regexp_like(col, '^(ABC|XYZ|PQR)');

I had to collect information from various sources to put together a functioning TabLayout. The following is presented as a complete use case that can be modified as needed.

Make sure the module build.gradle file contains a dependency on com.android.support:design.

dependencies {
    compile 'com.android.support:design:23.1.1'
}

In my case, I am creating an About activity in the application with a TabLayout. I added the following section to AndroidMainifest.xml. Setting the parentActivityName allows the home arrow to take the user back to the main activity.

<!-- android:configChanges="orientation|screenSize" makes the activity not reload when the orientation changes. -->
<activity
    android:name=".AboutActivity"
    android:label="@string/about_app"
    android:theme="@style/MyApp.About"
    android:parentActivityName=".MainActivity"
    android:configChanges="orientation|screenSize" >

    <!-- android.support.PARENT_ACTIVITY is necessary for API <= 15. -->
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".MainActivity" />
</activity>

styles.xml contains the following entries. This app has a white AppBar for the main activity and a blue AppBar for the About activity. We need to set colorPrimaryDark for the About activity so that the status bar above the AppBar is blue.

<style name="MyApp" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/blue</item>
</style>

<style name="MyApp.About" />

<!-- ThemeOverlay.AppCompat.Dark.ActionBar" makes the text and the icons in the AppBar white. -->
<style name="MyApp.DarkAppBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="MyApp.AppBarOverlay" parent="ThemeOverlay.AppCompat.ActionBar" />

<style name="MyApp.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

There is also a styles.xml (v19). It is located at src/main/res/values-v19/styles.xml. This file is only applied if the API of the device is >= 19.

<!-- android:windowTranslucentStatus requires API >= 19.  It makes the system status bar transparent.
  When it is specified the root layout should include android:fitsSystemWindows="true".
  colorPrimaryDark goes behind the status bar, which is then darkened by the overlay. -->
<style name="MyApp.About">
    <item name="android:windowTranslucentStatus">true</item>
    <item name="colorPrimaryDark">@color/blue</item>
</style>

AboutActivity.java contains the following code. In my case I have a fixed number of tabs (7) so I could remove all the code dealing with dynamic tabs.

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;

        setContentView(R.layout.about_coordinatorlayout);

        // We need to use the SupportActionBar from android.support.v7.app.ActionBar until the minimum API is >= 21.
        Toolbar supportAppBar = (Toolbar) findViewById(R.id.about_toolbar);
        setSupportActionBar(supportAppBar);

        // Display the home arrow on supportAppBar.
        final ActionBar appBar = getSupportActionBar();
        assert appBar != null;// This assert removes the incorrect warning in Android Studio on the following line that appBar might be null.
        appBar.setDisplayHomeAsUpEnabled(true);

        //  Setup the ViewPager.
        ViewPager aboutViewPager = (ViewPager) findViewById(R.id.about_viewpager);
        assert aboutViewPager != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutViewPager might be null.
        aboutViewPager.setAdapter(new aboutPagerAdapter(getSupportFragmentManager()));

        // Setup the TabLayout and connect it to the ViewPager.
        TabLayout aboutTabLayout = (TabLayout) findViewById(R.id.about_tablayout);
        assert aboutTabLayout != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutTabLayout might be null.
        aboutTabLayout.setupWithViewPager(aboutViewPager);
    }

    public class aboutPagerAdapter extends FragmentPagerAdapter {
        public aboutPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        // Get the count of the number of tabs.
        public int getCount() {
            return 7;
        }

        @Override
        // Get the name of each tab.  Tab numbers start at 0.
        public CharSequence getPageTitle(int tab) {
            switch (tab) {
                case 0:
                    return getString(R.string.version);

                case 1:
                    return getString(R.string.permissions);

                case 2:
                    return getString(R.string.privacy_policy);

                case 3:
                    return getString(R.string.changelog);

                case 4:
                    return getString(R.string.license);

                case 5:
                    return getString(R.string.contributors);

                case 6:

                default:
                    return "";
            }
        }

        @Override
        // Setup each tab.
        public Fragment getItem(int tab) {
            return AboutTabFragment.createTab(tab);
        }
    }
}

AboutTabFragment.java is used to populate each tab. In my case, the first tab has a LinearLayout inside of a ScrollView and all the others have a WebView as the root layout.

import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;

public class AboutTabFragment extends Fragment {
    private int tabNumber;

    // AboutTabFragment.createTab stores the tab number in the bundle arguments so it can be referenced from onCreate().
    public static AboutTabFragment createTab(int tab) {
        Bundle thisTabArguments = new Bundle();
        thisTabArguments.putInt("Tab", tab);
        AboutTabFragment thisTab = new AboutTabFragment();
        thisTab.setArguments(thisTabArguments);
        return thisTab;
    }

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

        // Store the tab number in tabNumber.
        tabNumber = getArguments().getInt("Tab");
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View tabLayout;

        // Load the about tab layout.  Tab numbers start at 0.
        if (tabNumber == 0) {
            // Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
            // The fragment will take care of attaching the root automatically.
            tabLayout = inflater.inflate(R.layout.about_tab_version, container, false);
        } else { // load a WebView for all the other tabs.  Tab numbers start at 0.
            // Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
            // The fragment will take care of attaching the root automatically.
            tabLayout = inflater.inflate(R.layout.about_tab_webview, container, false);
            WebView tabWebView = (WebView) tabLayout;

            switch (tabNumber) {
                case 1:
                tabWebView.loadUrl("file:///android_asset/about_permissions.html");
                    break;

                case 2:
                    tabWebView.loadUrl("file:///android_asset/about_privacy_policy.html");
                    break;

                case 3:
                    tabWebView.loadUrl("file:///android_asset/about_changelog.html");
                    break;

                case 4:
                    tabWebView.loadUrl("file:///android_asset/about_license.html");
                    break;

                case 5:
                    tabWebView.loadUrl("file:///android_asset/about_contributors.html");
                    break;

                case 6:
                    tabWebView.loadUrl("file:///android_asset/about_links.html");
                    break;

                default:
                    break;
            }
        }

        return tabLayout;
    }
}

about_coordinatorlayout.xml is as follows:

One of my SQL jobs had the same issue. It involved uploadaing data from one server to another. The error occurred because I was using sql Server Agent Service Account. I created a Credential using a UserId (that uses Window authentication) common to all servers. Then created a Proxy using this credential. Used the proxy in sql server job and it is running fine.

Use HTML's anchors:

Main Page:

<a href="sample.html#sushi">Sushi</a>
<a href="sample.html#bbq">BBQ</a>

Sample Page:

<div id='sushi'><a name='sushi'></a></div>
<div id='bbq'><a name='bbq'></a></div>

@bku_drytt's solution didn't do it for me.

I solved it by additionally changing every occurence of 14.0 to 12.0 and v140 to v120 manually in the .vcxproj files.

Then it compiled!

This will convert to a numeric value without the need to cast or specify length or digits:

STRING_COL+0.0

If your column is an INT, can leave off the .0 to avoid decimals:

STRING_COL+0

This approach worked for me but it is not as specific as your question:

App.Current.MainWindow

$focusable:
  'a[href]',
  'area[href]',
  'button',
  'details',
  'input',
  'iframe',
  'select',
  'textarea',

  // these are actually case sensitive but i'm not listing out all the possible variants
  '[contentEditable=""]',
  '[contentEditable="true"]',
  '[contentEditable="TRUE"]',

  '[tabindex]:not([tabindex^="-"])',
  ':not([disabled])';

I'm creating a SCSS list of all focusable elements and I thought this might help someone due to this question's Google rank.

A few things to note:

• I changed :not([tabindex="-1"]) to :not([tabindex^="-"]) because it's perfectly plausible to generate -2 somehow. Better safe than sorry right?
• Adding :not([tabindex^="-"]) to all the other focusable selectors is completely pointless. When using [tabindex]:not([tabindex^="-"]) it already includes all elements that you'd be negating with :not!
• I included :not([disabled]) because disabled elements can never be focusable. So again it's useless to add it to every single element.

For me the Issue was I didn't run the setup as Administrator, after running the setup as administrator the message go away and I was prompted to install and continue process.

One shouldn't use set_yticklabels to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter), which is usually undesired. The easiest is to set the respective tick_params:

ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)

or

ax.tick_params(labelsize=8)

in case both axes shall have the same size.

Of course using the rcParams as in @tmdavison's answer is possible as well.

Use a ternary operator:

echo '<option value="'.$value.'"'.($value=='United States' ? 'selected="selected"' : '').'>'.$value.'</option>';

And while you're at it, you could use printf to make your code more readable/manageable:

printf('<option value="%s" %s>%s</option>',
    $value,
    $value == 'United States' ? 'selected="selected"' : ''
    $value);

Since none of the answers mentioned the upcoming Ranges library, which is available in the standard library since C++20, and currently separately available on GitHub as range-v3, I would like to add a way to perform this conversion using it.

To modify the string in-place:

str |= action::transform([](unsigned char c){ return std::tolower(c); });

To generate a new string:

auto new_string = original_string
    | view::transform([](unsigned char c){ return std::tolower(c); });

(Don't forget to #include <cctype> and the required Ranges headers.)

Note: the use of unsigned char as the argument to the lambda is inspired by cppreference, which states:

Like all other functions from <cctype>, the behavior of std::tolower is undefined if the argument's value is neither representable as unsigned char nor equal to EOF. To use these functions safely with plain chars (or signed chars), the argument should first be converted to unsigned char:

char my_tolower(char ch)
{
    return static_cast<char>(std::tolower(static_cast<unsigned char>(ch)));
}

Similarly, they should not be directly used with standard algorithms when the iterator's value type is char or signed char. Instead, convert the value to unsigned char first:

std::string str_tolower(std::string s) {
    std::transform(s.begin(), s.end(), s.begin(), 
                // static_cast<int(*)(int)>(std::tolower)         // wrong
                // [](int c){ return std::tolower(c); }           // wrong
                // [](char c){ return std::tolower(c); }          // wrong
                   [](unsigned char c){ return std::tolower(c); } // correct
                  );
    return s;
}

I want to do the same thing but to append a script tag in other frame!

var url = 'library.js'; 
var script = window.parent.frames[1].document.createElement('script' ); 
script.type = 'text/javascript'; 
script.src = url;
$('head',window.parent.frames[1].document).append(script);
