Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.

The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process's virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That's why you are getting the access violation error.

I had the same problem after upgrading from .NET 4.5 to .NET 4.5.1. What fixed it for me was running this command:

netsh winsock reset

By using NULL without any quotes.

UPDATE `tablename` SET `fieldName` = NULL;

If you're willing to consider a different approach altogether to detecting illegal copies of your images, you could consider watermarking. (from 1.4)

...inserts copyright information into the digital object without the loss of quality. Whenever the copyright of a digital object is in question, this information is extracted to identify the rightful owner. It is also possible to encode the identity of the original buyer along with the identity of the copyright holder, which allows tracing of any unauthorized copies.

While it's also a complex field, there are techniques that allow the watermark information to persist through gross image alteration: (from 1.9)

... any signal transform of reasonable strength cannot remove the watermark. Hence a pirate willing to remove the watermark will not succeed unless they debase the document too much to be of commercial interest.

of course, the faq calls implementing this approach: "...very challenging" but if you succeed with it, you get a high confidence of whether the image is a copy or not, rather than a percentage likelihood.

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

dumpsys window windows gives more detail about the current activity:

adb shell "dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'"
  mCurrentFocus=Window{41d2c970 u0 com.android.launcher/com.android.launcher2.Launcher}
  mFocusedApp=AppWindowToken{4203c170 token=Token{41b77280 ActivityRecord{41b77a28 u0 com.android.launcher/com.android.launcher2.Launcher t3}}}

However in order to find the process ID (e.g. to kill the current activity), use dumpsys activity, and grep on "top-activity":

adb shell "dumpsys activity | grep top-activity"
    Proc # 0: fore  F/A/T  trm: 0 3074:com.android.launcher/u0a8 (top-activity)

adb shell "kill 3074"

Yes - I am 4 years late.

But I found a way to do this in one line without having to create an external script; by calling powershell commands from a batch file.

Thanks to TessellatingHeckler - without outputting to a text file (I set the powershell command in a variable, because it's pretty messy in one long line inside a for loop).

@echo off
set "psCommand=powershell -Command "$pword = read-host 'Enter Password' -AsSecureString ; ^
    $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^
        [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)""
for /f "usebackq delims=" %%p in (`%psCommand%`) do set password=%%p
echo %password%

Originally I wrote it to output to a text file, then read from that text file. But the above method is better. In one extremely long, near incomprehensible line:

@echo off
powershell -Command $pword = read-host "Enter password" -AsSecureString ; $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword) ; [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR) > .tmp.txt & set /p password=<.tmp.txt & del .tmp.txt
echo %password%

I'll break this down - you can split it up over a few lines using caret ^, which is much nicer...

@echo off
powershell -Command $pword = read-host "Enter password" -AsSecureString ; ^
    $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword) ; ^
        [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR) > .tmp.txt 
set /p password=<.tmp.txt & del .tmp.txt
echo %password%

This article explains what the powershell commands are doing; essentially it gets input using Read-Host -AsSecureString - the following two lines convert that secure string back into plain text, the output (plaintext password) is then sent to a text file using >.tmp.txt. That file is then read into a variable and deleted.

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Laravel 5.8 to 8.0 and above

The SERVER_PORT environment variable will be picked up and used by Laravel. Either do:

export SERVER_PORT="8080"
php artisan serve

Or set SERVER_PORT=8080 in your .env file.

Earlier versions of Laravel:

For port 8080:

 php artisan serve --port=8080

And if you want to run it on port 80, you probably need to sudo:

sudo php artisan serve --port=80

The PHP refresh after 5 seconds didn't work for me when opening a Save As dialogue to save a file: (header('Content-type: text/plain'); header("Content-Disposition: attachment; filename=$filename>");)

After the Save As link was clicked, and file was saved, the timed refresh stopped on the calling page.

However, thank you very much, ibu's javascript solution just kept on ticking and refreshing my webpage, which is what I needed for my specific application. So thank you ibu for posting javascript solution to php problem here.

You can use javascript to redirect after some time

setTimeout(function () {    
    window.location.href = 'http://www.google.com'; 
},5000); // 5 seconds

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

Add:

• DELIMITER at the beginning and end of the SP.
• DROP PROCEDURE IF EXISTS validar_egreso; at the beginning
• When calling the SP, use @variableName.

This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).

DROP PROCEDURE IF EXISTS `validar_egreso`;

DELIMITER $$

CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
    IN codigo_producto VARCHAR(100),
    IN cantidad INT,
    OUT valido INT(11)
)
BEGIN

    DECLARE resta INT;
    SET resta = 0;

    SELECT (codigo_producto - cantidad) INTO resta;

    IF(resta > 1) THEN
       SET valido = 1;
    ELSE
       SET valido = -1;
    END IF;

    SELECT valido;
END $$

DELIMITER ;

-- execute the stored procedure
CALL validar_egreso(4, 1, @val);

-- display the result
select @val;

Yes, there is a maximum, but it's system dependent. Try it and see, doubling until you hit a limit then searching down. At least with Sun JRE 1.6 on linux you get interesting if not always informative error messages (peregrino is netbook running 32 bit ubuntu with 2G RAM and no swap):

peregrino:$ java -Xmx4096M -cp bin WheelPrimes 
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

peregrino:$ java -Xmx4095M -cp bin WheelPrimes 
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

peregrino:$ java -Xmx4092M -cp bin WheelPrimes 
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size

peregrino:$ java -Xmx4000M -cp bin WheelPrimes 
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

(experiment reducing from 4000M until)

peregrino:$ java -Xmx2686M -cp bin WheelPrimes 
(normal execution)

Most are self explanatory, except -Xmx4095M which is rather odd (maybe a signed/unsigned comparison?), and that it claims to reserve 2686M on a 2GB machine with no swap. But it does hint that the maximum size is 4G not 2G for a 32 bit VM, if the OS allows you to address that much.

Rather than browse the ouput of the :ls command and delete (unload, wipe..) a buffer by specifying its number, I find that using file names is often more effective.

For instance, after I opened a couple of .txt file to refresh my memories of some fine point.. copy and paste a few lines of text to use as a template of sorts.. etc. I would type the following:

:bd txt <Tab>

Note that the matching string does not have to be at the start of the file name.

The above displays the list of file names that match 'txt' at the bottom of the screen and keeps the :bd command I initially typed untouched, ready to be completed.

Here's an example:

doc1.txt doc2.txt
:bd txt 

I could backspace over the 'txt' bit and type in the file name I wish to delete, but where this becomes really convenient is that I don't have to: if I hit the Tab key a second time, Vim automatically completes my command with the first match:

:bd doc1.txt

If I want to get rid of this particular buffer I just need to hit Enter.

And if the buffer I want to delete happens to be the second (third.. etc.) match, I only need to keep hitting the Tab key to make my :bd command cycle through the list of matches.

Naturally, this method can also be used to switch to a given buffer via such commands as :b.. :sb.. etc.

This approach is particularly useful when the 'hidden' Vim option is set, because the buffer list can quickly become quite large, covering several screens, and making it difficult to spot the particular buffer I am looking for.

To make the most of this feature, it's probably best to read the following Vim help file and tweak the behavior of Tab command-line completion accordingly so that it best suits your workflow:

:help wildmode

The behavior I described above results from the following setting, which I chose for consistency's sake in order to emulate bash completion:

:set wildmode=list:longest,full

As opposed to using buffer numbers, the merit of this approach is that I usually remember at least part of a given file name letting me target the buffer directly rather than having to first look up its number via the :ls command.

To remove the last commit from git, you can simply run

git reset --hard HEAD^ 

If you are removing multiple commits from the top, you can run

git reset --hard HEAD~2 

to remove the last two commits. You can increase the number to remove even more commits.

More info here.

Git tutoturial here provides help on how to purge repository:

you want to remove the file from history and add it to the .gitignore to ensure it is not accidentally re-committed. For our examples, we're going to remove Rakefile from the GitHub gem repository.

git clone https://github.com/defunkt/github-gem.git

cd github-gem

git filter-branch --force --index-filter \
  'git rm --cached --ignore-unmatch Rakefile' \
  --prune-empty --tag-name-filter cat -- --all

Now that we've erased the file from history, let's ensure that we don't accidentally commit it again.

echo "Rakefile" >> .gitignore

git add .gitignore

git commit -m "Add Rakefile to .gitignore"

If you're happy with the state of the repository, you need to force-push the changes to overwrite the remote repository.

git push origin master --force

Taking Chetan Kumar solution and in case you need to apply to a map[string]int

package main

import (
    "fmt"
    "reflect"
)

type BaseStats struct {
    Hp           int
    HpMax        int
    Mp           int
    MpMax        int
    Strength     int
    Speed        int
    Intelligence int
}

type Stats struct {
    Base map[string]int
    Modifiers []string
}

func StatsCreate(stats BaseStats) Stats {
    s := Stats{
        Base: make(map[string]int),
    }

    //Iterate through the fields of a struct
    v := reflect.ValueOf(stats)
    typeOfS := v.Type()

    for i := 0; i< v.NumField(); i++ {
        val := v.Field(i).Interface().(int)
        s.Base[typeOfS.Field(i).Name] = val
    }
    return s
}

func (s Stats) GetBaseStat(id string) int {
    return s.Base[id]
}


func main() {
    m := StatsCreate(BaseStats{300, 300, 300, 300, 10, 10, 10})

    fmt.Println(m.GetBaseStat("Hp"))
}

You can't.

One workaround is to create clone environment, and then remove original one:

(remember about deactivating current environment with deactivate on Windows and source deactivate on macOS/Linux)

conda create --name new_name --clone old_name
conda remove --name old_name --all # or its alias: `conda env remove --name old_name`

There are several drawbacks of this method:

1. it redownloads packages - you can use --offline flag to disable it,
2. time consumed on copying environment's files,
3. temporary double disk usage.

There is an open issue requesting this feature.

I tried almost all of these suggestions, but they were all returning empty values. If anyone else has this issue, I found this handy function on php.net (http://php.net/manual/en/function.get-current-user.php):

get_current_user();
$username = get_current_user();
echo $username;

This was the only way I was finally able to get the user's active directory username. If none of the above answers has worked, give this a try.

You can use a heredoc to do this e.g.

ftp -n $Server <<End-Of-Session
# -n option disables auto-logon

user anonymous "$Password"
binary
cd $Directory
put "$Filename.lsm"
put "$Filename.tar.gz"
bye
End-Of-Session

so the ftp process is fed on stdin with everything up to End-Of-Session. A useful tip for spawning any process, not just ftp! Note that this saves spawning a separate process (echo, cat etc.). Not a major resource saving, but worth bearing in mind.

I want to share an approach commented about and briefly discussed but show an actual example that I am currently using to help unit test EF-based services.

First, I would love to use the in-memory provider from EF Core, but this is about EF 6. Furthermore, for other storage systems like RavenDB, I'd also be a proponent of testing via the in-memory database provider. Again--this is specifically to help test EF-based code without a lot of ceremony.

Here are the goals I had when coming up with a pattern:

• It must be simple for other developers on the team to understand
• It must isolate the EF code at the barest possible level
• It must not involve creating weird multi-responsibility interfaces (such as a "generic" or "typical" repository pattern)
• It must be easy to configure and setup in a unit test

I agree with previous statements that EF is still an implementation detail and it's okay to feel like you need to abstract it in order to do a "pure" unit test. I also agree that ideally, I would want to ensure the EF code itself works--but this involves a sandbox database, in-memory provider, etc. My approach solves both problems--you can safely unit test EF-dependent code and create integration tests to test your EF code specifically.

The way I achieved this was through simply encapsulating EF code into dedicated Query and Command classes. The idea is simple: just wrap any EF code in a class and depend on an interface in the classes that would've originally used it. The main issue I needed to solve was to avoid adding numerous dependencies to classes and setting up a lot of code in my tests.

This is where a useful, simple library comes in: Mediatr. It allows for simple in-process messaging and it does it by decoupling "requests" from the handlers that implement the code. This has an added benefit of decoupling the "what" from the "how". For example, by encapsulating the EF code into small chunks it allows you to replace the implementations with another provider or totally different mechanism, because all you are doing is sending a request to perform an action.

Utilizing dependency injection (with or without a framework--your preference), we can easily mock the mediator and control the request/response mechanisms to enable unit testing EF code.

First, let's say we have a service that has business logic we need to test:

public class FeatureService {

  private readonly IMediator _mediator;

  public FeatureService(IMediator mediator) {
    _mediator = mediator;
  }

  public async Task ComplexBusinessLogic() {
    // retrieve relevant objects

    var results = await _mediator.Send(new GetRelevantDbObjectsQuery());
    // normally, this would have looked like...
    // var results = _myDbContext.DbObjects.Where(x => foo).ToList();

    // perform business logic
    // ...    
  }
}

Do you start to see the benefit of this approach? Not only are you explicitly encapsulating all EF-related code into descriptive classes, you are allowing extensibility by removing the implementation concern of "how" this request is handled--this class doesn't care if the relevant objects come from EF, MongoDB, or a text file.

Now for the request and handler, via MediatR:

public class GetRelevantDbObjectsQuery : IRequest<DbObject[]> {
  // no input needed for this particular request,
  // but you would simply add plain properties here if needed
}

public class GetRelevantDbObjectsEFQueryHandler : IRequestHandler<GetRelevantDbObjectsQuery, DbObject[]> {
  private readonly IDbContext _db;

  public GetRelevantDbObjectsEFQueryHandler(IDbContext db) {
    _db = db;
  }

  public DbObject[] Handle(GetRelevantDbObjectsQuery message) {
    return _db.DbObjects.Where(foo => bar).ToList();
  }
}

As you can see, the abstraction is simple and encapsulated. It's also absolutely testable because in an integration test, you could test this class individually--there are no business concerns mixed in here.

So what does a unit test of our feature service look like? It's way simple. In this case, I'm using Moq to do mocking (use whatever makes you happy):

[TestClass]
public class FeatureServiceTests {

  // mock of Mediator to handle request/responses
  private Mock<IMediator> _mediator;

  // subject under test
  private FeatureService _sut;

  [TestInitialize]
  public void Setup() {

    // set up Mediator mock
    _mediator = new Mock<IMediator>(MockBehavior.Strict);

    // inject mock as dependency
    _sut = new FeatureService(_mediator.Object);
  }

  [TestCleanup]
  public void Teardown() {

    // ensure we have called or expected all calls to Mediator
    _mediator.VerifyAll();
  }

  [TestMethod]
  public void ComplexBusinessLogic_Does_What_I_Expect() {
    var dbObjects = new List<DbObject>() {
      // set up any test objects
      new DbObject() { }
    };

    // arrange

    // setup Mediator to return our fake objects when it receives a message to perform our query
    // in practice, I find it better to create an extension method that encapsulates this setup here
    _mediator.Setup(x => x.Send(It.IsAny<GetRelevantDbObjectsQuery>(), default(CancellationToken)).ReturnsAsync(dbObjects.ToArray()).Callback(
    (GetRelevantDbObjectsQuery message, CancellationToken token) => {
       // using Moq Callback functionality, you can make assertions
       // on expected request being passed in
       Assert.IsNotNull(message);
    });

    // act
    _sut.ComplexBusinessLogic();

    // assertions
  }

}

You can see all we need is a single setup and we don't even need to configure anything extra--it's a very simple unit test. Let's be clear: This is totally possible to do without something like Mediatr (you would simply implement an interface and mock it for tests, e.g. IGetRelevantDbObjectsQuery), but in practice for a large codebase with many features and queries/commands, I love the encapsulation and innate DI support Mediatr offers.

If you're wondering how I organize these classes, it's pretty simple:

- MyProject
  - Features
    - MyFeature
      - Queries
      - Commands
      - Services
      - DependencyConfig.cs (Ninject feature modules)

Organizing by feature slices is beside the point, but this keeps all relevant/dependent code together and easily discoverable. Most importantly, I separate the Queries vs. Commands--following the Command/Query Separation principle.

This meets all my criteria: it's low-ceremony, it's easy to understand, and there are extra hidden benefits. For example, how do you handle saving changes? Now you can simplify your Db Context by using a role interface (IUnitOfWork.SaveChangesAsync()) and mock calls to the single role interface or you could encapsulate committing/rolling back inside your RequestHandlers--however you prefer to do it is up to you, as long as it's maintainable. For example, I was tempted to create a single generic request/handler where you'd just pass an EF object and it would save/update/remove it--but you have to ask what your intention is and remember that if you wanted to swap out the handler with another storage provider/implementation, you should probably create explicit commands/queries that represent what you intend to do. More often than not, a single service or feature will need something specific--don't create generic stuff before you have a need for it.

There are of course caveats to this pattern--you can go too far with a simple pub/sub mechanism. I've limited my implementation to only abstracting EF-related code, but adventurous developers could start using MediatR to go overboard and message-ize everything--something good code review practices and peer reviews should catch. That's a process issue, not an issue with MediatR, so just be cognizant of how you're using this pattern.

You wanted a concrete example of how people are unit testing/mocking EF and this is an approach that's working successfully for us on our project--and the team is super happy with how easy it is to adopt. I hope this helps! As with all things in programming, there are multiple approaches and it all depends on what you want to achieve. I value simplicity, ease of use, maintainability, and discoverability--and this solution meets all those demands.

You have to add one jar : jackson-annotations-2.1.2.jar You can download it from here and add it to the class path If you are using the gradle then add the following dependency.

compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:2.5.2'

This introduces a new paradigm to HTML/CSS, but using an <input readonly="true"> would allow you to append an input:focus selector to then alter the background-image

This of course would require applying specific CSS to the input itself to override browser defaults but it does go to show that click actions can indeed be triggered without the use of Javascript.

i think you need to remove the ';' from the end of the java path.

You can use system() or %x[] depending what kind of result you need.

system() returning true if the command was found and ran successfully, false otherwise.

>> s = system 'uptime'
10:56  up 3 days, 23:10, 2 users, load averages: 0.17 0.17 0.14
=> true
>> s.class
=> TrueClass
>> $?.class
=> Process::Status

%x[..] on the other hand saves the results of the command as a string:

>> result = %x[uptime]
=> "13:16  up 4 days,  1:30, 2 users, load averages: 0.39 0.29 0.23\n"
>> p result 
"13:16  up 4 days,  1:30, 2 users, load averages: 0.39 0.29 0.23\n"
>> result.class
=> String

Th blog post by Jay Fields explains in detail the differences between using system, exec and %x[..] .

At least on one system that is not very uncommon, they do not print the same:

~/src> uname -m
i686
~/src> gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu

bf8ce99c

Notice how the pointer version adds a 0x prefix, for instance. Always use %p since it knows about the size of pointers, and how to best represent them as text.

This function will prevent entry of anything other than numbers and a single dot.

function validateQty(el, evt) {_x000D_
   var charCode = (evt.which) ? evt.which : event.keyCode_x000D_

        return false;_x000D_
    if (charCode == 46) {_x000D_

    }_x000D_
};

<input type="text" onkeypress='return validateQty(this,event);'>

You will need to clone the ArrayList by hand (by iterating over it and copying each element to a new ArrayList), because clone() will not do it for you. Reason for this is that the objects contained in the ArrayList may not implement Clonable themselves.

Edit: ... and that is exactly what Varkhan's code does.

If you want to do it using .map() or just want to know how it works you can do it like this:

var added=false;
$.map(arr, function(elementOfArray, indexInArray) {
 if (elementOfArray.id == productID) {
   elementOfArray.price = productPrice;
   added = true;
 }
}
if (!added) {
  arr.push({id: productID, price: productPrice})
}

The function handles each element separately. The .inArray() proposed in other answers is probably the more efficient way to do it.

If you want to add item to the beginning of the collection you can use prepend:

$item->prepend($product, 'key');

jQuery has a function that can do this:

1. include the following script in your head:

   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script>
   

   (or just download the jQuery.js file online and include it locally)

2. use this script to toggle the check box when the input is clicked:

   var toggle = false;
   $("#INPUTNAMEHERE").click(function() {
           $("input[type=checkbox]").attr("checked",!toggle);
           toggle = !toggle;
   }); 
   

That should do what you want if I understood what you were trying to do.

Write your own:

template<class T>
bool checkElementIsInSet(const T& elem, const std::set<T>& container)
{
  return container.find(elem) != container.end();
}

just do

npm i --save circular-json

then in your js file

const CircularJSON = require('circular-json');
...
const json = CircularJSON.stringify(obj);

NOTE: I have nothing to do with this package. But I do use it for this.

Update 2020

Please note CircularJSON is in maintenance only and flatted is its successor.

If you need to find the largest and second largest element in an existing array, see the answers above (Schwern's answer contains the approach I would've used).

However; needing to find the largest and second largest element in an existing array typically indicates a design flaw. Entire arrays don't magically appear - they come from somewhere, which means that the most efficient approach is to keep track of "current largest and current second largest" while the array is being created.

For example; for your original code the data is coming from the user; and by keeping track of "largest and second largest value that the user entered" inside of the loop that gets values from the user the overhead of tracking the information will be hidden by the time spent waiting for the user to press key/s, you no longer need to do a search afterwards while the user is waiting for results, and you no longer need an array at all.

It'd be like this:

int main() {
    int largest1 = 0, largest2 = 0, i, temp;

    printf("enter number of elements you want in array");
    scanf("%d", &n);
    printf("enter elements");
    for (i = 0; i < n; i++) {
        scanf("%d", &temp);
        if(temp >= largest1) {
            largest2 = largest1;
            largest1 = temp;
        } else if(temp > largest2) {
            largest2 = temp;
        }
    }
    printf("First and second largest number is %d and %d ", largest1, largest2);
}

I needed to encode my parameters with ISO-8859-1, so the addingPercentEncoding() method doesn't work for me. I made a solution my self in Swift 4:

extension String {

  // Url percent encoding according to RFC3986 specifications
  // https://tools.ietf.org/html/rfc3986#section-2.1
  func urlPercentEncoded(withAllowedCharacters allowedCharacters: 
    CharacterSet, encoding: String.Encoding) -> String {
    var returnStr = ""

    // Compute each char seperatly
    for char in self {
      let charStr = String(char)
      let charScalar = charStr.unicodeScalars[charStr.unicodeScalars.startIndex]
      if allowedCharacters.contains(charScalar) == false,
        let bytesOfChar = charStr.data(using: encoding) {
        // Get the hexStr of every notAllowed-char-byte and put a % infront of it, append the result to the returnString
        for byte in bytesOfChar {
          returnStr += "%" + String(format: "%02hhX", byte as CVarArg)
        }
      } else {
        returnStr += charStr
      }
    }

    return returnStr
  }

}

Usage:

"aouäöü!".urlPercentEncoded(withAllowedCharacters: .urlQueryAllowed,
                                         encoding: .isoLatin1) 
// Results in -> "aou%E4%F6%FC!"

What actually worked for me in the end was this:

Intent myIntent = new Intent(getBaseContext(), MainActivity.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myIntent);

Try to use getActivity(); This will solve your problem.

I started using maven on my machine first time in while. Got this error: Could not transfer artifact from/to central (https://repo.maven.apache.org/maven2) No such file or directory Cleaned up ~/.m2/repository directory. Don't experience this problem again

Assuming they always exist and are not part of your data, this will work:

declare @string varchar(8000) = '23;chair,red [$3]'
select substring(@string, charindex(';', @string) + 1, charindex(' [', @string) - charindex(';', @string) - 1)

When you run into a problem where it cats all.txt into all.txt, You can try check all.txt is existing or not, if exists, remove

Like this:

[ -e $"all.txt" ] && rm $"all.txt"

In my case I wasn't aware that the PHP run by Apache was different from the one run by CLI. That might be the case if during configuration in httpd.conf you specified a PHP module, not being the default one your CLI uses.

On android 2.2 you can input multiple language and switch by sliding on the spacebar. Go in the settings under "language and keyboard" and then "Android Keyboard", "Input language".

Hope this helps.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

It worked for me instead using format .To work with time just use parse and toString() methods

String localTime="6:11"; LocalTime localTime = LocalTime.parse(localtime)

LocalTime lt = 6:11; localTime = lt.toString()

blazeroni already made it pretty clear, I just want to add few points.

• <merge> is used for optimizing layouts.It is used for reducing unnecessary nesting.
• when a layout containing <merge> tag is added into another layout,the <merge> node is removed and its child view is added directly to the new parent.

Use the C Standard Library function getchar() instead as getch() is not a standard function, being provided by Borland TURBO C for MS-DOS/Windows only.

printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");  
getchar();    
 

Here, getchar() expects you to press the return key so the printf statement should be press ENTER to continue. Even if you press another key, you still need to press ENTER:

printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");  
getchar();    

If you are using Windows then you can use getch()

printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getch();   
//if you press any character it will continue ,  
//but this is not a standard c function.

char ch;
printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");    
//here also if you press any other key will wait till pressing ENTER
scanf("%c",&ch); //works as getchar() but here extra variable is required.      

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

if value of the Key is coming as String and you want to convert it to JSONObject,

First take your key.value into a String variable like

 String data = yourResponse.yourKey;

then convert into JSONArray

JSONObject myObj=new JSONObject(data);

You can import the css file on App.vue, inside the style tag.

<style>
  @import './assets/styles/yourstyles.css';
</style>

Also, make sure you have the right loaders installed, if you need any.

You need to remove the / before the [. Predicates (the parts in [ ]) shouldn't have slashes immediately before them. Also, to select the Employee element itself, you should leave off the /text() at the end or otherwise you'd just be selecting the whitespace text values immediately under the Employee element.

//Employee[@id='4']

Edit: As Jens points out in the comments, // can be very slow because it searches the entire document for matching nodes. If the structure of the documents you're working with is going to be consistent, you are probably best off using a full path, for example:

/Employees/Employee[@id='4']

Let me recommend mem_top tool I created

It helped me to solve a similar issue

It just instantly shows top suspects for memory leaks in a Python program

Your problem is with this line:

number4 = list(cow[n])

It tries to take cow[n], which returns an integer, and make it a list. This doesn't work, as demonstrated below:

>>> a = 1
>>> list(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>>

Perhaps you meant to put cow[n] inside a list:

number4 = [cow[n]]

See a demonstration below:

>>> a = 1
>>> [a]
[1]
>>>

Also, I wanted to address two things:

1. Your while-statement is missing a : at the end.
2. It is considered very dangerous to use input like that, since it evaluates its input as real Python code. It would be better here to use raw_input and then convert the input to an integer with int.

To split up the digits and then add them like you want, I would first make the number a string. Then, since strings are iterable, you can use sum:

>>> a = 137
>>> a = str(a)
>>> # This way is more common and preferred
>>> sum(int(x) for x in a)
11
>>> # But this also works
>>> sum(map(int, a))
11
>>>

Referring to Gamaliel 's answer: $args is an array of the arguments that are passed into a script at runtime - as such cannot be used the way Gamaliel is using it. This is actually working:

$myPath = 'C:\whatever.file'
# get actual Acl entry
$myAcl = Get-Acl "$myPath"
$myAclEntry = "Domain\User","FullControl","Allow"
$myAccessRule = New-Object System.Security.AccessControl.FileSystemAccessRule($myAclEntry)
# prepare new Acl
$myAcl.SetAccessRule($myAccessRule)
$myAcl | Set-Acl "$MyPath"
# check if added entry present
Get-Acl "$myPath" | fl

There is a setting window.zoom that can enlarge the entire window content including the top menus and side nav tree. Setting this to 1 on a 4k monitor makes the content similar to a 1080p monitor of the same physical size.

I know this is 5 years later, but the replies above don't address what was wrong with your software. (Well, Yuushi's does, but I didn't realise until I had typed this - doh!). They answer the question in the title How can I initialize C++ object member variables in the constructor? This is about the other questions: Am I using the right approach but the wrong syntax? Or should I be coming at this from a different direction?

Programming style is largely a matter of opinion, but an alternative view to doing as much as possible in a constructor is to keep constructors down to a bare minimum, often having a separate initialization function. There is no need to try to cram all initialization into a constructor, never mind trying to force things at times into the constructors initialization list.

So, to the point, what was wrong with your software?

private:
    ThingOne* ThingOne;
    ThingTwo* ThingTwo;

Note that after these lines, ThingOne (and ThingTwo) now have two meanings, depending on context.

Outside of BigMommaClass, ThingOne is the class you created with #include "ThingOne.h"

Inside BigMommaClass, ThingOne is a pointer.

That is assuming the compiler can even make sense of the lines and doesn't get stuck in a loop thinking that ThingOne is a pointer to something which is itself a pointer to something which is a pointer to ...

Later, when you write

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

bear in mind that inside of BigMommaClass your ThingOne is a pointer.

If you change the declarations of the pointers to include a prefix (p)

private:
    ThingOne* pThingOne;
    ThingTwo* pThingTwo;

Then ThingOne will always refer to the class and pThingOne to the pointer.

It is then possible to rewrite

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

as

pThingOne = new ThingOne(100);
pThingTwo = new ThingTwo(numba1, numba2);

which corrects two problems: the double meaning problem, and the missing new. (You can leave this-> if you like!)

With that in place, I can add the following lines to a C++ program of mine and it compiles nicely.

class ThingOne{public:ThingOne(int n){};};
class ThingTwo{public:ThingTwo(int x, int y){};};

class BigMommaClass {

    public:
            BigMommaClass(int numba1, int numba2);

    private:
            ThingOne* pThingOne;
            ThingTwo* pThingTwo;
};

BigMommaClass::BigMommaClass(int numba1, int numba2)
{
    pThingOne = new ThingOne(numba1 + numba2);
    pThingTwo = new ThingTwo(numba1, numba2);
};

When you wrote

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

the use of this-> tells the compiler that the left hand side ThingOne is intended to mean the pointer. However we are inside BigMommaClass at the time and it's not necessary.

The problem is with the right hand side of the equals where ThingOne is intended to mean the class. So another way to rectify your problems would have been to write

this->ThingOne = new ::ThingOne(100);
this->ThingTwo = new ::ThingTwo(numba1, numba2);

or simply

ThingOne = new ::ThingOne(100);
ThingTwo = new ::ThingTwo(numba1, numba2);

using :: to change the compiler's interpretation of the identifier.

Use PHP error handling functions to handle errors. How you do it depends on your needs. This system will intercept all errors and forward it however you want it Or supress it if you ask it to do so

http://php.net/manual/en/book.errorfunc.php

Using vh on mobile devices is not going to work with 100vh, due to their design choices using the entire height of the device not including any address bars etc.

If you are looking for a layout including div heights proportionate to the true view height I use the following pure css solution:

:root {
  --devHeight: 86vh; //*This value changes
}

.div{
    height: calc(var(--devHeight)*0.10); //change multiplier to suit required height
}

You have two options for setting the viewport height, manually set the --devHeight to a height that works (but you will need to enter this value for each type of device you are coding for)

or

Use javascript to get the window height and then update --devheight on loading and refreshing the viewport (however this does require using javascript and is not a pure css solution)

Once you obtain your correct view height you can create multiple divs at an exact percentage of total viewport height by simply changing the multiplier in each div you assign the height to.

0.10 = 10% of view height 0.57 = 57% of view height

Hope this might help someone ;)

There are two ways to do the redirect. Both apply to either subprocess.Popen or subprocess.call.

1. Set the keyword argument shell = True or executable = /path/to/the/shell and specify the command just as you have it there.

2. Since you're just redirecting the output to a file, set the keyword argument

   stdout = an_open_writeable_file_object
   

   where the object points to the output file.

subprocess.Popen is more general than subprocess.call.

Popen doesn't block, allowing you to interact with the process while it's running, or continue with other things in your Python program. The call to Popen returns a Popen object.

call does block. While it supports all the same arguments as the Popen constructor, so you can still set the process' output, environmental variables, etc., your script waits for the program to complete, and call returns a code representing the process' exit status.

returncode = call(*args, **kwargs) 

is basically the same as calling

returncode = Popen(*args, **kwargs).wait()

call is just a convenience function. It's implementation in CPython is in subprocess.py:

def call(*popenargs, timeout=None, **kwargs):
    """Run command with arguments.  Wait for command to complete or
    timeout, then return the returncode attribute.

    The arguments are the same as for the Popen constructor.  Example:

    retcode = call(["ls", "-l"])
    """
    with Popen(*popenargs, **kwargs) as p:
        try:
            return p.wait(timeout=timeout)
        except:
            p.kill()
            p.wait()
            raise

As you can see, it's a thin wrapper around Popen.

export PGPASSWORD=<password>
psql -h <host> -d <database> -U <user_name> -p <port> -a -w -f <file>.sql

Not mentioned above. You could also crate a DateTime object by providing a timestamp as string in the constructor with a leading @ sign.

$dt = new DateTime('@123456789');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('F j, Y - G:i');

See the documentation about compound formats: https://www.php.net/manual/en/datetime.formats.compound.php

for those who want some official document to confirm the behavior

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

https://www.gnu.org/software/make/manual/html_node/Environment.html

This code also working .

#!/bin/bash
FILE=$1
if [ -f $FILE ]; then
 echo "File '$FILE' Exists"
else
 echo "The File '$FILE' Does Not Exist"
fi

As @filoxo said, you can use document.querySelectorAll.

If you know that there is only one element with the class you are looking for, or you are interested only in the first one, you can use:

document.querySelector('.class1.class2');

BTW, while .class1.class2 indicates an element with both classes, .class1 .class2 (notice the whitespace) indicates an hierarchy - and element with class class2 which is inside en element with class class1:

<div class='class1'>
  <div>
    <div class='class2'>
      :
      :

And if you want to force retrieving a direct child, use > sign (.class1 > .class2):

<div class='class1'>
  <div class='class2'>
    :
    :

A solution for me was to create a UILabel and add it to the UIButton as a subview. Finally I added a constraint to center it within the button.

UILabel * myTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 75, 75)];
myTextLabel.text = @"Some Text";
myTextLabel.translatesAutoresizingMaskIntoConstraints = false;

[myButton addSubView:myTextLabel];

// Add Constraints
[[myTextLabel centerYAnchor] constraintEqualToAnchor:myButton.centerYAnchor].active = true;
[[myTextLabel centerXAnchor] constraintEqualToAnchor:myButton.centerXAnchor].active = true; 

int i;
int j;

int * const ptr1 = &i;

The compiler will stop you changing ptr1.

const int * ptr2 = &i;

The compiler will stop you changing *ptr2.

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

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

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

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

You can also have a pointer with both features:

const int * const ptr3 = &i;

ptr3 = &j; // error
*ptr3 = 7; // error

For Swift 3

Create a function for button action first and then add the function to your button target

func buttonAction(sender: UIButton!) {
    print("Button tapped")
}

button.addTarget(self, action: #selector(buttonAction),for: .touchUpInside)

If you want a window as a whole to have a specific size, you can just give it the size you want with the geometry command. That's really all you need to do.

For example:

mw.geometry("500x500")

Though, you'll also want to make sure that the widgets inside the window resize properly, so change how you add the frame to this:

back.pack(fill="both", expand=True)

If you want to rewrite a line on console, print a control character \r (carriage return).

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
Iterator<Integer> myListIterator = myCoords.iterator(); 
while (myListIterator.hasNext()) {
    Integer coord = myListIterator.next();     
    System.out.print("\r");
    System.out.print(coord);
    Thread.sleep(2000);
}

Just use HTML5, input type=”number”

#case_date= 03/31/2020   

#Above is the value stored in case_date in format(mm/dd/yyyy )

demo=case_date.split("/")
new_case_date = demo[1]+"-"+demo[0]+"-"+demo[2]
#new format of date is (dd/mm/yyyy) test by printing it 
print(new_case_date)

Let's start with a qualitative description of what we want to do (much of this is said in Ben Straub's answer). We've made some number of commits, five of which changed a given file, and we want to revert the file to one of the previous versions. First of all, git doesn't keep version numbers for individual files. It just tracks content - a commit is essentially a snapshot of the work tree, along with some metadata (e.g. commit message). So, we have to know which commit has the version of the file we want. Once we know that, we'll need to make a new commit reverting the file to that state. (We can't just muck around with history, because we've already pushed this content, and editing history messes with everyone else.)

So let's start with finding the right commit. You can see the commits which have made modifications to given file(s) very easily:

git log path/to/file

If your commit messages aren't good enough, and you need to see what was done to the file in each commit, use the -p/--patch option:

git log -p path/to/file

Or, if you prefer the graphical view of gitk

gitk path/to/file

You can also do this once you've started gitk through the view menu; one of the options for a view is a list of paths to include.

Either way, you'll be able to find the SHA1 (hash) of the commit with the version of the file you want. Now, all you have to do is this:

# get the version of the file from the given commit
git checkout <commit> path/to/file
# and commit this modification
git commit

(The checkout command first reads the file into the index, then copies it into the work tree, so there's no need to use git add to add it to the index in preparation for committing.)

If your file may not have a simple history (e.g. renames and copies), see VonC's excellent comment. git can be directed to search more carefully for such things, at the expense of speed. If you're confident the history's simple, you needn't bother.

const oldFunction = params => {
  // do something
};

const clonedFunction = (...args) => oldFunction(...args);

My solution:

function isAssociative(array $array)
{
    return array_keys(array_merge($array)) !== range(0, count($array) - 1);
}

array_merge on a single array will reindex all integer keys, but not other. For example:

array_merge([1 => 'One', 3 => 'Three', 'two' => 'Two', 6 => 'Six']);

// This will returns [0 => 'One', 1 => 'Three', 'two' => 'Two', 2 => 'Six']

So if a list (a non-associative array) is created ['a', 'b', 'c'] then a value is removed unset($a[1]) then array_merge is called, the list is reindexed starting from 0.

Generally, it's a very good practice to keep it very close.

In some cases, there will be a consideration such as performance which justifies pulling the variable out of the loop.

In your example, the program creates and destroys the string each time. Some libraries use a small string optimization (SSO), so the dynamic allocation could be avoided in some cases.

Suppose you wanted to avoid those redundant creations/allocations, you would write it as:

for (int counter = 0; counter <= 10; counter++) {
   // compiler can pull this out
   const char testing[] = "testing";
   cout << testing;
}

or you can pull the constant out:

const std::string testing = "testing";
for (int counter = 0; counter <= 10; counter++) {
   cout << testing;
}

Do most compilers realize that the variable has already been declared and just skip that portion, or does it actually create a spot for it in memory each time?

It can reuse the space the variable consumes, and it can pull invariants out of your loop. In the case of the const char array (above) - that array could be pulled out. However, the constructor and destructor must be executed at each iteration in the case of an object (such as std::string). In the case of the std::string, that 'space' includes a pointer which contains the dynamic allocation representing the characters. So this:

for (int counter = 0; counter <= 10; counter++) {
   string testing = "testing";
   cout << testing;
}

would require redundant copying in each case, and dynamic allocation and free if the variable sits above the threshold for SSO character count (and SSO is implemented by your std library).

Doing this:

string testing;
for (int counter = 0; counter <= 10; counter++) {
   testing = "testing";
   cout << testing;
}

would still require a physical copy of the characters at each iteration, but the form could result in one dynamic allocation because you assign the string and the implementation should see there is no need to resize the string's backing allocation. Of course, you wouldn't do that in this example (because multiple superior alternatives have already been demonstrated), but you might consider it when the string or vector's content varies.

So what do you do with all those options (and more)? Keep it very close as a default -- until you understand the costs well and know when you should deviate.

shortest/friendliest solution

After becoming frustrated with the too many limitations of cut, I wrote my own replacement, which I called cuts for "cut on steroids".

cuts provides what is likely the most minimalist solution to this and many other related cut/paste problems.

One example, out of many, addressing this particular question:

$ cat text.txt
0   1        2 3
0 1          2   3 4

$ cuts 2 text.txt
2
2

cuts supports:

• auto-detection of most common field-delimiters in files (+ ability to override defaults)
• multi-char, mixed-char, and regex matched delimiters
• extracting columns from multiple files with mixed delimiters
• offsets from end of line (using negative numbers) in addition to start of line
• automatic side-by-side pasting of columns (no need to invoke paste separately)
• support for field reordering
• a config file where users can change their personal preferences
• great emphasis on user friendliness & minimalist required typing

and much more. None of which is provided by standard cut.

If you want it outside of loop then use the below code.

<?php
$author_id = get_post_field ('post_author', $cause_id);
$display_name = get_the_author_meta( 'display_name' , $author_id ); 
echo $display_name;
?>

You have to change the line

product userFromJSON = mapper.readValue(userDataJSON, product.class);

to

product[] userFromJSON = mapper.readValue(userDataJSON, product[].class);

since you are deserializing an array (btw: you should start your class names with upper case letters as mentioned earlier). Additionally you have to create setter methods for your fields or mark them as public in order to make this work.

Edit: You can also go with Steven Schlansker's suggestion and use

List<product> userFromJSON =
        mapper.readValue(userDataJSON, new TypeReference<List<product>>() {});

instead if you want to avoid arrays.

Every time an entity is updated in the database the version field will be increased by one. Every operation that updates the entity in the database will have appended WHERE version = VERSION_THAT_WAS_LOADED_FROM_DATABASE to its query.

In checking affected rows of your operation the jpa framework can make sure there was no concurrent modification between loading and persisting your entity because the query would not find your entity in the database when it's version number has been increased between load and persist.

In XCode 7.3 I encountered the same question, I 've made the mistake because: Name in (info.plist -->Bundle identifier) is not the same as (target-->build settings -->packaging-->Product bundle identifier). Just make the same, that solved the problem.

If you don't want to use temporary tables here is a split string like function you can use

SET @Array = 'one,two,three,four';
SET @ArrayIndex = 2;
SELECT CASE 
    WHEN @Array REGEXP CONCAT('((,).*){',@ArrayIndex,'}') 
    THEN SUBSTRING_INDEX(SUBSTRING_INDEX(@Array,',',@ArrayIndex+1),',',-1) 
    ELSE NULL
END AS Result;

• SUBSTRING_INDEX(string, delim, n) returns the first n
• SUBSTRING_INDEX(string, delim, -1) returns the last only
• REGEXP '((delim).*){n}' checks if there are n delimiters (i.e. you are in bounds)

I had to use Take(n) method, then transform to list, Worked like a charm:

    var listTest = (from x in table1
                     join y in table2
                     on x.field1 equals y.field1
                     orderby x.id descending
                     select new tempList()
                     {
                         field1 = y.field1,
                         active = x.active
                     }).Take(10).ToList();

This code works too:

$("input[reference=12345].myclass").css('border', '#000 solid 1px');

Using the MaximumSize and MinimumSize properties of the form will fix the form size, and prevent the user from resizing the form, while keeping the form default FormBorderStyle.

this.MaximumSize = new Size(XX, YY);
this.MinimumSize = new Size(X, Y);

There was a really good discussion on this over at comp.lang.python last year. It answers your question pretty thoroughly.

Imports are pretty straightforward really. Just remember the following:

'import' and 'from xxx import yyy' are executable statements. They execute when the running program reaches that line.

If a module is not in sys.modules, then an import creates the new module entry in sys.modules and then executes the code in the module. It does not return control to the calling module until the execution has completed.

If a module does exist in sys.modules then an import simply returns that module whether or not it has completed executing. That is the reason why cyclic imports may return modules which appear to be partly empty.

Finally, the executing script runs in a module named __main__, importing the script under its own name will create a new module unrelated to __main__.

Take that lot together and you shouldn't get any surprises when importing modules.

To create a new commit that 'undoes' the changes of a past commit, use:

$ git revert <commit-hash>

It's also possible to actually remove a commit from an arbitrary point in the past by rebasing and then resetting, but you really don't want to do that if you have already pushed your commits to another repository (or someone else has pulled from you).

If your previous commit is a merge commit you can run this command

$ git revert -m 1 <commit-hash>

See schacon.github.com/git/howto/revert-a-faulty-merge.txt for proper ways to re-merge an un-merged branch

I'd like to point out few more solutions to transposing columns and rows in SQL.

The first one is - using CURSOR. Although the general consensus in the professional community is to stay away from SQL Server Cursors, there are still instances whereby the use of cursors is recommended. Anyway, Cursors present us with another option to transpose rows into columns.

• Vertical expansion

  Similar to the PIVOT, the cursor has the dynamic capability to append more rows as your dataset expands to include more policy numbers.

• Horizontal expansion

  Unlike the PIVOT, the cursor excels in this area as it is able to expand to include newly added document, without altering the script.

• Performance breakdown

  The major limitation of transposing rows into columns using CURSOR is a disadvantage that is linked to using cursors in general – they come at significant performance cost. This is because the Cursor generates a separate query for each FETCH NEXT operation.

Another solution of transposing rows into columns is by using XML.

The XML solution to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation.

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

• Vertical expansion

  Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

• Horizontal expansion

  Unlike the PIVOT, newly added documents can be displayed without altering the script.

• Performance breakdown

  In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

Python datetimes are a little clunky. Use arrow.

> str(arrow.utcnow())
'2014-05-17T01:18:47.944126+00:00'

Arrow has essentially the same api as datetime, but with timezones and some extra niceties that should be in the main library.

A format compatible with Javascript can be achieved by:

arrow.utcnow().isoformat().replace("+00:00", "Z")
'2018-11-30T02:46:40.714281Z'

Javascript Date.parse will quietly drop microseconds from the timestamp.

I'm not sure, but I think the second parameter is a red herring.

Both .Rows and .Columns take two optional parameters: RowIndex and ColumnIndex. Try to use ColumnIndex, e.g. Rows(ColumnIndex:=2), generates an error for both .Rows and .Columns.

My feeling it's inherited in some sense from the Cells(RowIndex,ColumnIndex) Property but only the first parameter is appropriate.

When you typed in sudo sendmailconfig, you should have been prompted to configure sendmail.

For reference, the files that are updated during configuration are located at the following (in case you want to update them manually):

/etc/mail/sendmail.conf
/etc/cron.d/sendmail
/etc/mail/sendmail.mc

You can test sendmail to see if it is properly configured and setup by typing the following into the command line:

$ echo "My test email being sent from sendmail" | /usr/sbin/sendmail [email protected]

The following will allow you to add smtp relay to sendmail:

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

Add the following lines to sendmail.mc, but before the MAILERDEFINITIONS. Make sure you update your smtp server.

define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash -o /etc/mail/auth/client-info.db')dnl

Invoke creation sendmail.cf (alternatively run make -C /etc/mail):

m4 sendmail.mc > sendmail.cf

Restart the sendmail daemon:

service sendmail restart

Sleep meaning that thread is do nothing. Time is too large beacuse anthor thread query,but not disconnect server, default wait_timeout=28800;so you can set values smaller,eg 10. also you can kill the thread.

If you know in advance which fields to use to make the comparison, then other people gave right answers.
What you may be interested in is to sort your collection in case you don't know at compile-time which criteria to apply. Imagine you have a program dealing with cities:

    protected Set<City> cities;
    (...)
    Field temperatureField = City.class.getDeclaredField("temperature");
    Field numberOfInhabitantsField = City.class.getDeclaredField("numberOfInhabitants");
    Field rainfallField = City.class.getDeclaredField("rainfall");
    program.showCitiesSortBy(temperatureField, numberOfInhabitantsField, rainfallField);
    (...)
    public void showCitiesSortBy(Field... fields) {
        List<City> sortedCities = new ArrayList<City>(cities);
        Collections.sort(sortedCities, new City.CityMultiComparator(fields));
        for (City city : sortedCities) {
            System.out.println(city.toString());
        }
    }

where you can replace hard-coded field names by field names deduced from a user request in your program.

In this example, City.CityMultiComparator<City> is a static nested class of class City implementing Comparator:

    public static class CityMultiComparator implements Comparator<City> {
        protected List<Field> fields;

        public CityMultiComparator(Field... orderedFields) {
            fields = new ArrayList<Field>();
            for (Field field : orderedFields) {
                fields.add(field);
            }
        }

        @Override
        public int compare(City cityA, City cityB) {
            Integer score = 0;
            Boolean continueComparison = true;
            Iterator itFields = fields.iterator();

            while (itFields.hasNext() && continueComparison) {
                Field field = itFields.next();
                Integer currentScore = 0;
                if (field.getName().equalsIgnoreCase("temperature")) {
                    currentScore = cityA.getTemperature().compareTo(cityB.getTemperature());
                } else if (field.getName().equalsIgnoreCase("numberOfInhabitants")) {
                    currentScore = cityA.getNumberOfInhabitants().compareTo(cityB.getNumberOfInhabitants());
                } else if (field.getName().equalsIgnoreCase("rainfall")) {
                    currentScore = cityA.getRainfall().compareTo(cityB.getRainfall());
                }
                if (currentScore != 0) {
                    continueComparison = false;
                }
                score = currentScore;
            }

            return score;
        }
    }

You may want to add an extra layer of precision, to specify, for each field, whether sorting should be ascendant or descendant. I guess a solution is to replace Field objects by objects of a class you could call SortedField, containing a Field object, plus another field meaning ascendant or descendant.

You could use JavaScriptSerializer.

Surprised that no one suggested it:

System.DateTime.UtcNow.ToString("u").Replace(' ','T')

# Using PowerShell Core to demo

# Lowercase "u" format
[System.DateTime]::UtcNow.ToString("u")
> 2020-02-06 01:00:32Z

# Lowercase "u" format with replacement
[System.DateTime]::UtcNow.ToString("u").Replace(' ','T')
> 2020-02-06T01:00:32Z

The UniversalSortableDateTimePattern gets you almost all the way to what you want (which is more an RFC 3339 representation).

Added: I decided to use the benchmarks that were in answer https://stackoverflow.com/a/43793679/653058 to compare how this performs.

tl:dr; it's at the expensive end but still just a little over half a millisecond on my crappy old laptop :-)

Implementation:

[Benchmark]
public string ReplaceU()
{
   var text = dateTime.ToUniversalTime().ToString("u").Replace(' ', 'T');
   return text;
}

The JQuery code is fine. You must execute in the ready handler not in the window load event.

<script type="text/javascript">
$(function(){
  var aspForm  = $("form#aspnetForm");
  var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm);
  firstInput.focus();
});
</script>

Update

I tried with the example of Karim79(thanks for the example) and it works fine: http://jsfiddle.net/2sMfU/

this is how I do it

JAVASCRIPT:

var module = angular.module('yourModuleName', ['ui.router']);

module.run( ['$rootScope', '$state', '$stateParams',
                      function ($rootScope,   $state,   $stateParams) {
    $rootScope.$state = $state;
    $rootScope.$stateParams = $stateParams; 
}
]);

HTML:

<pre id="uiRouterInfo">
      $state = {{$state.current.name}}
      $stateParams = {{$stateParams}}
      $state full url = {{ $state.$current.url.source }}    
</pre>

Option 1:

You can set CMake variables at command line like this:

cmake -D CMAKE_C_COMPILER="/path/to/your/c/compiler/executable" -D CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable" /path/to/directory/containing/CMakeLists.txt

See this to learn how to create a CMake cache entry.

Option 2:

In your shell script build_ios.sh you can set environment variables CC and CXX to point to your C and C++ compiler executable respectively, example:

export CC=/path/to/your/c/compiler/executable
export CXX=/path/to/your/cpp/compiler/executable
cmake /path/to/directory/containing/CMakeLists.txt

Option 3:

Edit the CMakeLists.txt file of "Assimp": Add these lines at the top (must be added before you use project() or enable_language() command)

set(CMAKE_C_COMPILER "/path/to/your/c/compiler/executable")
set(CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable")

See this to learn how to use set command in CMake. Also this is a useful resource for understanding use of some of the common CMake variables.

# horizental line?
ax = plt.axes()
# three ticks:
ax.yaxis.set_major_locator(LinearLocator(3))

Other answers generally pointed out the difference between Bash and a POSIX shell standard. However, when writing portable shell scripts and being used to Bash syntax, a list of typical bashisms and corresponding pure POSIX solutions is very handy. Such list has been compiled when Ubuntu switched from Bash to Dash as default system shell and can be found here: https://wiki.ubuntu.com/DashAsBinSh

Moreover, there is a great tool called checkbashisms that checks for bashisms in your script and comes handy when you want to make sure that your script is portable.

I've never liked how this was provider was implemented like this : /

Basically, it makes every registry value a PSCustomObject object with PsPath, PsParentPath, PsChildname, PSDrive and PSProvider properties and then a property for its actual value. So even though you asked for the item by name, to get its value you have to use the name once more.

Event delegation makes use of two often overlooked features of JavaScript events: event bubbling and the target element.When an event is triggered on an element, for example a mouse click on a button, the same event is also triggered on all of that element’s ancestors. This process is known as event bubbling; the event bubbles up from the originating element to the top of the DOM tree.

Imagine an HTML table with 10 columns and 100 rows in which you want something to happen when the user clicks on a table cell. For example, I once had to make each cell of a table of that size editable when clicked. Adding event handlers to each of the 1000 cells would be a major performance problem and, potentially, a source of browser-crashing memory leaks. Instead, using event delegation, you would add only one event handler to the table element, intercept the click event and determine which cell was clicked.

You can use your own code. You don't need to use the looping structure, if you don't want to use the looping structure as you said above. Only you have to focus to remove space or trim the String of the list.

If you are using java8 you can simply trim the String using the single line of the code:

myList = myList.stream().map(String :: trim).collect(Collectors.toList());

The importance of the above line is, in the future, you can use a List or set as well. Now you can use your own code:

if(myList.contains("A")){
    //true
}else{
    // false
}

Something like the standard Collection.toArray(T[]) should do what you need (note that ArrayList implements Collection):

TypeA[] array = a.toArray(new TypeA[a.size()]);

On a side note, you should consider defining a to be of type List<TypeA> rather than ArrayList<TypeA>, this avoid some implementation specific definition that may not really be applicable for your application.

Also, please see this question about the use of a.size() instead of 0 as the size of the array passed to a.toArray(TypeA[])

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

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

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

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

I find, if the data is imported, you may need to use the trim command on top of it, to get your details. =LEFT(TRIM(B2),8) In my case, I was using it to find a IP range. 10.3.44.44 with mask 255.255.255.0, so response is: 10.3.44 Kind of handy.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

This Snippet of code is taken from: http://en.kioskea.net/forum/affich-267274-how-to-convert-number-into-text-in-excel

The simplest way to update is as follows:

1. Go to the start screen for Android Studio. If it automatically opens a project when you open it, close that project (not exit).

2. At the bottom there will be a check for updates link which you can use to update to the latest version.

If you are looking for Uniformly distributed pseudorandom integers use:

randi([13, 20])

There are a couple of approaches:

1. Use a Bag alorithm like the sets contained in Google Collections.

2. Create mutable container which you can use in the Map:

    class My{
        String word;
        int count;
    }

And use put("word", new My("Word") ); Then you can check if it exists and increment when adding.

Avoid rolling your own solution using lists, because if you get innerloop searching and sorting, your performance will stink. The first HashMap solution is actually quite fast, but a proper like that found in Google Collections is probably better.

Counting words using Google Collections, looks something like this:

    HashMultiset s = new HashMultiset();
    s.add("word");
    s.add("word");
    System.out.println(""+s.count("word") );

Using the HashMultiset is quite elegent, because a bag-algorithm is just what you need when counting words.

While I do love using CHECKSUM, I feel that a better way to go is using NEWID(), just because you don't have to go through a complicated math to generate simple numbers .

ROUND( 1000 *RAND(convert(varbinary, newid())), 0)

You can replace the 1000 with whichever number you want to set as the limit, and you can always use a plus sign to create a range, let's say you want a random number between 100 and 200, you can do something like :

100 + ROUND( 100 *RAND(convert(varbinary, newid())), 0)

Putting it together in your query :

UPDATE CattleProds 
SET SheepTherapy= ROUND( 1000 *RAND(convert(varbinary, newid())), 0)
WHERE SheepTherapy IS NULL

This jQuery worked for me:

$("#banner-contenedor").css('width');

This will get you the computed width

(Following is a late but complete answer)

FileReader methods support

FileReader.readAsBinaryString() is deprecated. Don't use it! It's no longer in the W3C File API working draft:

void abort();
void readAsArrayBuffer(Blob blob);
void readAsText(Blob blob, optional DOMString encoding);
void readAsDataURL(Blob blob);

NB: Note that File is a kind of extended Blob structure.

Mozilla still implements readAsBinaryString() and describes it in MDN FileApi documentation:

void abort();
void readAsArrayBuffer(in Blob blob); Requires Gecko 7.0
void readAsBinaryString(in Blob blob);
void readAsDataURL(in Blob file);
void readAsText(in Blob blob, [optional] in DOMString encoding);

The reason behind readAsBinaryString() deprecation is in my opinion the following: the standard for JavaScript strings are DOMString which only accept UTF-8 characters, NOT random binary data. So don't use readAsBinaryString(), that's not safe and ECMAScript-compliant at all.

We know that JavaScript strings are not supposed to store binary data but Mozilla in some sort can. That's dangerous in my opinion. Blob and typed arrays (ArrayBuffer and the not-yet-implemented but not necessary StringView) were invented for one purpose: allow the use of pure binary data, without UTF-8 strings restrictions.

XMLHttpRequest upload support

XMLHttpRequest.send() has the following invocations options:

void send();
void send(ArrayBuffer data);
void send(Blob data);
void send(Document data);
void send(DOMString? data);
void send(FormData data);

XMLHttpRequest.sendAsBinary() has the following invocations options:

void sendAsBinary(   in DOMString body );

sendAsBinary() is NOT a standard and may not be supported in Chrome.

Solutions

So you have several options:

1. send() the FileReader.result of FileReader.readAsArrayBuffer ( fileObject ). It is more complicated to manipulate (you'll have to make a separate send() for it) but it's the RECOMMENDED APPROACH.
2. send() the FileReader.result of FileReader.readAsDataURL( fileObject ). It generates useless overhead and compression latency, requires a decompression step on the server-side BUT it's easy to manipulate as a string in Javascript.
3. Being non-standard and sendAsBinary() the FileReader.result of FileReader.readAsBinaryString( fileObject )

MDN states that:

The best way to send binary content (like in files upload) is using ArrayBuffers or Blobs in conjuncton with the send() method. However, if you want to send a stringifiable raw data, use the sendAsBinary() method instead, or the StringView (Non native) typed arrays superclass.

The difference comes in when you use the struct.

The first way you have to do:

struct myStruct aName;

The second way allows you to remove the keyword struct.

myStruct aName;

Similar to blubb's answer. I suggest building them with lambda functions to reduce code. Like this:

User = lambda passwd, hair, name: {'password':passwd, 'hair':hair, 'name':name}

#Col      Username       Password      Hair Color  Real Name
config = {'st3v3' : User('password',   'blonde',   'Steve Booker'),
          'blubb' : User('12345678',   'black',    'Bubb Ohaal'),
          'suprM' : User('kryptonite', 'black',    'Clark Kent'),
          #...
         }
#...

config['st3v3']['password']  #> password
config['blubb']['hair']      #> black

This does smell like you may want to make a class, though.

Or, as MarkM noted, you could use namedtuple

from collections import namedtuple
#...

User = namedtuple('User', ['password', 'hair', 'name']}

#Col      Username       Password      Hair Color  Real Name
config = {'st3v3' : User('password',   'blonde',   'Steve Booker'),
          'blubb' : User('12345678',   'black',    'Bubb Ohaal'),
          'suprM' : User('kryptonite', 'black',    'Clark Kent'),
          #...
         }
#...

config['st3v3'].password   #> passwd
config['blubb'].hair       #> black

The typical answer is this:

1. In Excel, File/Save As, select CSV, save your current sheet.

2. transfer to a holding directory on the Pg server the postgres user can access

3. in PostgreSQL:

   COPY mytable FROM '/path/to/csv/file' WITH CSV HEADER; -- must be superuser
   

But there are other ways to do this too. PostgreSQL is an amazingly programmable database. These include:

1. Write a module in pl/javaU, pl/perlU, or other untrusted language to access file, parse it, and manage the structure.

2. Use CSV and the fdw_file to access it as a pseudo-table

3. Use DBILink and DBD::Excel

4. Write your own foreign data wrapper for reading Excel files.

The possibilities are literally endless....

To get the DB path for iOS, the simplest way is to:

1. Launch your app in a simulator
2. Pause it at any time in the debugger
3. Go to the console (where you have (lldb)) and type: po RLMRealm.defaultRealmPath

Tada...you have the path to your realm database

First, find the columns that have 'unnamed', then drop those columns. Note: You should Add inplace = True to the .drop parameters as well.

df.drop(df.columns[df.columns.str.contains('unnamed',case = False)],axis = 1, inplace = True)

You will need have to download InternetExplorer driver executable on your system, download it from the source (http://code.google.com/p/selenium/downloads/list) after download unzip it and put on the place of somewhere in your computer. In my example, I will place it to D:\iexploredriver.exe

Then you have write below code in your eclipse main class

   System.setProperty("webdriver.ie.driver", "D:/iexploredriver.exe");
   WebDriver driver = new InternetExplorerDriver();

You can group your dependencies within a different project with packaging pom as described by Sonatypes Best Practices:

<project>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>base-dependencies</artifactId>
    <groupId>es.uniovi.innova</groupId>
    <version>1.0.0</version>
    <packaging>pom</packaging>
    <dependencies>
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4</version>
        </dependency>
    </dependencies>
</project>

and reference them from your parent-pom (watch the dependency <type>pom</type>):

<project>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>base</artifactId>
    <groupId>es.uniovi.innova</groupId>
    <version>1.0.0</version>
    <packaging>pom</packaging>
    <dependencies>
        <dependency>
            <artifactId>base-dependencies</artifactId>
            <groupId>es.uniovi.innova</groupId>
            <version>1.0.0</version>
            <type>pom</type>
        </dependency>
    </dependencies>
</project>

Your child-project inherits this parent-pom as before. But now, the mail dependency can be excluded in the child-project within the dependencyManagement block:

<project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>test</groupId>
    <artifactId>jruby</artifactId>

            </dependency>
        </dependencies>

If you're running on Passenger, then the default is to run in production, in your apache conf:

<VirtualHost *:80>
  ServerName application_name.rails.local
  DocumentRoot "/Users/rails/application_name/public"
  RailsEnv production ## This is the default
</VirtualHost>

If you're just running a local server with mongrel or webrick, you can do:

./script/server -e production

or in bash:

RAILS_ENV=production ./script/server

actually overriding the RAILS_ENV constant in the enviornment.rb should probably be your last resort, as it's probably not going to stay set (see another answer I gave on that)

GitHub isn't able to authenticate you. So, either you aren't setup with an SSH key, because you haven't set one up on your machine, or your key isn't associated with your GitHub account.

You can also use the HTTPS URL instead of the SSH/git URL to avoid having to deal with SSH keys. This is GitHub's recommended method.

Further, GitHub has a help page specifically for that error message, and explains in more detail everything you could check.

There are two ways to achieve this.

1- As already proposed u can set the background of your spinner as custom 9 patch Image with all the adjustments made into it .

android:background="@drawable/btn_dropdown" 
android:clickable="true"
android:dropDownVerticalOffset="-10dip"
android:dropDownHorizontalOffset="0dip"
android:gravity="center"

If you want your Spinner to show With various different background colors i would recommend making the drop down image transparent, & loading that spinner in a relative layout with your color set in.

btn _dropdown is as:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:state_window_focused="false" android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_window_focused="false" android:state_enabled="false"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_pressed="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_focused="true" android:state_enabled="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_focused="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:drawable="@drawable/spinner_default" />
</selector>

where the various states of pngwould define your various States of spinner seleti

i created a custom View DistributeLayout to do this.

I was trying to figure how to do this recently and while I like the most popular solution at the top, it simply would not work for me as I needed the names to be the alias's that I entered in the script so I used some batch files (with some help from a colleague) to accomplish custom table names.

The batch file that initiates the bcp has a line at the bottom of the script that executes another script that merges a template file with the header names and the file that was just exported with bcp using the code below. Hope this helps someone else that was in my situation.

echo Add headers from template file to exported sql files....
Echo School 0031
copy e:\genin\templates\TEMPLATE_Courses.csv + e:\genin\0031\courses0031.csv e:\genin\finished\courses0031.csv /b

I solved this issue this way:

Go to Run menu ====> click on Edit Configurations ====> Micellaneous and finaly uncheck the option Skip installation if APK has not changed

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

Daniel Hilgarth's answer above leads to a System.NotSupported exception With Entity-Framework. With Entity-Framework, it has to be:

table1.GroupBy(x => x.Text).Select(x => x.FirstOrDefault());

character varying(n), varchar(n) - (Both the same). value will be truncated to n characters without raising an error.

character(n), char(n) - (Both the same). fixed-length and will pad with blanks till the end of the length.

text - Unlimited length.

Example:

Table test:
   a character(7)
   b varchar(7)

insert "ok    " to a
insert "ok    " to b

We get the results:

a        | (a)char_length | b     | (b)char_length
----------+----------------+-------+----------------
"ok     "| 7              | "ok"  | 2

Call Wget for each link and set it to run in background.

I tried this Python code

with open('links.txt', 'r')as f1:      # Opens links.txt file with read mode
  list_1 = f1.read().splitlines()      # Get every line in links.txt
for i in list_1:                       # Iteration over each link
  !wget "$i" -bq                       # Call wget with background mode

Parameters :

      b - Run in Background
      q - Quiet mode (No Output)

In my case, I had a textbox that was attached to a datepicker. The only solution that worked for me was to handle it inside the onSelect event of the datepicker.

<input type="text"  id="bookdate">

$("#bookdate").datepicker({            
     onSelect: function (selected) {
         //handle change event here
     }
});

I am not sure if this applies to your situation, but I will post what worked for me.

I change my table view based on queries / searches to a database. For example, a database table contains Patient data. My initial table view in my program contains all Patients. I can then search query for Patients by firstName and lastName. I use the results of this query to repopulate my Observable list. Then I reset the items in the tableview by calling tableview.setItems(observableList):

/**
 * Searches the table for an existing Patient.
 */
@FXML
public void handleSearch() {
    String fname = this.fNameSearch.getText();
    String lname = this.lNameSearch.getText();
    LocalDate bdate = this.bDateSearch.getValue();

    if (this.nameAndDOBSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(fname, lname, bdate);
    } else if (this.birthDateSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(bdate);
    } else if (this.nameSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(fname, lname);
    }

    this.patientTable.setItems(this.patientData);
}

The if blocks update the ObservableList with the query results.

Edit: Not quite. See comments below.

Java doesn't directly run on anything. It needs to be converted to bytecode by a JVM.

Because JVMs exist for all major platforms, this makes Java platform-independent THROUGH the JVM.

After reading Java 7 Update 21 Security Improvements in Detail mention..

With the introduced changes it is most likely that no end-user is able to run your application when they are either self-signed or unsigned.

..I was wondering how this would go for loose class files - the 'simplest' applets of all.

Local file system

Your security settings have blocked a local application from running

That is the dialog seen for an applet consisting of loose class files being loaded off the local file system when the JRE is set to the default 'High' security setting.

Note that a slight quirk of the JRE only produced that on point 3 of.

1. Load the applet page to see a broken applet symbol that leads to an empty console.
   Open the Java settings and set the level to Medium.
   Close browser & Java settings.
2. Load the applet page to see the applet.
   Open the Java settings and set the level to High.
   Close browser & Java settings.
3. Load the applet page to see a broken applet symbol & the above dialog.

Internet

If you load the simple applet (loose class file) seen at this resizable applet demo off the internet - which boasts an applet element of:

<applet
    code="PlafChanger.class"
    codebase="."
    alt="Pluggable Look'n'Feel Changer appears here if Java is enabled"
    width='100%'
    height='250'>
<p>Pluggable Look'n'Feel Changer appears here in a Java capable browser.</p>
</applet>

It also seems to load successfully. Implying that:-

Applets loaded from the local file system are now subject to a stricter security sandbox than those loaded from the internet or a local server.

Security settings descriptions

As of Java 7 update 51.

• Very High: Most secure setting - Only Java applications identified by a non-expired certificate from a trusted authority will be allowed to run.
• High (minimum recommended): Java applications identified by a certificate from a trusted authority will be allowed to run.
• Medium - All Java applications will be allowed to run after presenting a security prompt.

Ensure 'idm.url' is set in property file and the property file is loaded

Try LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0). Best of all it's free!

Steps with version 4.35.1:

1. click 'Add Connection'

2. Click Next with 'Build data context automatically' and 'Default(LINQ to SQL)' selected.

3. Under 'Provider' choose 'SQL CE 4.0'.

4. Under 'Database' with 'Attach database file' selected, choose 'Browse' to select your .sdf file.

5. Click 'OK'.

6. Voila! It should show the tables in .sdf and be able to query it via right clicking the table or writing LINQ code in your favorite .NET language or even SQL. How cool is that?

It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

On Error Resume Next

If Err Then
    WScript.StdErr.WriteLine "error " & Err.Number
    WScript.Quit 1
End If

maybe that will help with windows scheduled tasks ...

this is from Java API "sort

public static void sort(List list) Sorts the specified list into ascending order, according to the natural ordering of its elements. All elements in the list must implement the Comparable interface. Furthermore, all elements in the list must be mutually comparable (that is, e1.compareTo(e2) must not throw a ClassCastException for any elements e1 and e2 in the list)."

it has to do with implementing the Comparable interface

Only Visual Studio 2015 Enterprise has code coverage built-in. See the feature matrix for details.

You can use the OpenCover.UI extension for code coverage check inside Visual Studio. It supports MSTest, nUnit, and xUnit.

The new version can be downloaded from here (release notes).

You simply want the File.GetLastWriteTime static method.

Example:

var lastModified = System.IO.File.GetLastWriteTime("C:\foo.bar");

Console.WriteLine(lastModified.ToString("dd/MM/yy HH:mm:ss"));

Note however that in the rare case the last-modified time is not updated by the system when writing to the file (this can happen intentionally as an optimisation for high-frequency writing, e.g. logging, or as a bug), then this approach will fail, and you will instead need to subscribe to file write notifications from the system, constantly listening.

In Addition to @Dev Blanked answer, if you want to use an existing bean that was created by Spring the code can be modified to:

@RunWith(MockitoJUnitRunner.class)
public class DemoTest {

    @Inject
    private ApplicationContext ctx;

    @Spy
    private SomeService service;

    @InjectMocks
    private Demo demo;

    @Before
    public void setUp(){
        service = ctx.getBean(SomeService.class);
    }

    /* ... */
}

This way you don't need to change your code (add another constructor) just to make the tests work.

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

What about this one?

var input = new List<string> { "a", "g", "e", "w", "p", "s", "q", "f", "x", "y", "i", "m", "c" };
var k = 3

var res = Enumerable.Range(0, (input.Count - 1) / k + 1)
                    .Select(i => input.GetRange(i * k, Math.Min(k, input.Count - i * k)))
                    .ToList();

As far as I know, GetRange() is linear in terms of number of items taken. So this should perform well.

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

Didn't find the answer I wanted, so I solved it myself:
modify a container div!

<div class="rotation"> <!-- Set the container div's css -->
  <div class="content" id='content-1'>This div gets scaled on hover</div>
</div>

<!-- Since there is no parent here the transform doesnt have specificity! -->
<div class="rotation content" id='content-2'>This div does not</div>

css you want to persist after executing $target.css()

.content:hover {
    transform: scale(1.5);
}

modify content's containing div with css()

$(".rotation").css("transform", "rotate(" + degrees + "deg)");

Codepen example

The solution is pretty easy... Searched for it for a while and it turns out that you just have to edit 2 config-files:

• /usr/my.cnf
• /etc/mysql/my.cnf

in both files you'll have to add:

[mysqld]
...
sql_mode=NO_ENGINE_SUBSTITUTION

At least, that's what's working for 5.6.24-2+deb.sury.org~precise+2

In addition to the answers above, you could use a small extension method:

public static class Extensions
{
   public static void Run(this string fileName, 
                          string workingDir=null, params string[] arguments)
    {
        using (var p = new Process())
        {
            var args = p.StartInfo;
            args.FileName = fileName;
            if (workingDir!=null) args.WorkingDirectory = workingDir;
            if (arguments != null && arguments.Any())
                args.Arguments = string.Join(" ", arguments).Trim();
            else if (fileName.ToLowerInvariant() == "explorer")
                args.Arguments = args.WorkingDirectory;
            p.Start();
        }
    }
}

and use it like so:

// open explorer window with given path
"Explorer".Run(path);   

// open a shell (remanins open)
"cmd".Run(path, "/K");

I'm afraid not—the simulator shares whatever network connection the OS is using. I filed a Radar bug report about simulating network conditions a while back; you might consider doing the same.

You should declare it with declarations array(meta property) of @NgModule as shown below (RC5 and later),

import {CoursesComponent} from './courses.component';

@NgModule({
  imports:      [ BrowserModule],
  declarations: [ AppComponent,CoursesComponent],  //<----here
  providers:    [],      
  bootstrap:    [ AppComponent ]
})

The Bootstrap3 .form-control is cool but for those who love or need the drop-down with button and ul option, here is the updated code. I have edited the code by Steve to fix jumping to the hash link and closing the drop-down after selection.

Thanks to Steve, Ben and Skelly!

$(".dropdown-menu li a").click(function () {
    var selText = $(this).text();
    $(this).closest('div').find('button[data-toggle="dropdown"]').html(selText + ' <span class="caret"></span>');
    $(this).closest('.dropdown').removeClass("open");
    return false;
});

Kill is definitly the wrong way! The PID will stay, Replicationsjobs will be killed etc. etc.

Some cloud solutions exist, such as macincloud (not free)

I'd print out the result of an2.getNodeName() as well for debugging purposes. My guess is that your tree crawling code isn't crawling to the nodes that you think it is. That suspicion is enhanced by the lack of checking for node names in your code.

Other than that, the javadoc for Node defines "getNodeValue()" to return null for Nodes of type Element. Therefore, you really should be using getTextContent(). I'm not sure why that wouldn't give you the text that you want.

Perhaps iterate the children of your tag node and see what types are there?

Tried this code and it works for me:

String xml = "<add job=\"351\">\n" +
             "    <tag>foobar</tag>\n" +
             "    <tag>foobar2</tag>\n" +
             "</add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = db.parse(bis);
Node n = doc.getFirstChild();
NodeList nl = n.getChildNodes();
Node an,an2;

for (int i=0; i < nl.getLength(); i++) {
    an = nl.item(i);
    if(an.getNodeType()==Node.ELEMENT_NODE) {
        NodeList nl2 = an.getChildNodes();

        for(int i2=0; i2<nl2.getLength(); i2++) {
            an2 = nl2.item(i2);
            // DEBUG PRINTS
            System.out.println(an2.getNodeName() + ": type (" + an2.getNodeType() + "):");
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getTextContent());
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getNodeValue());
            System.out.println(an2.getTextContent());
            System.out.println(an2.getNodeValue());
        }
    }
}

Output was:

#text: type (3): foobar foobar
#text: type (3): foobar2 foobar2

I have created a sample. May it will work for you.

var doneTypingInterval = 10;
var finaldoneTypingInterval = 500;

var oldData = $("p.content").html();

    if ($('#tyingBox').val) {
        typingTimer = setTimeout(function () {
            $("p.content").html('Typing...');
        }, doneTypingInterval);
    }
});

$('#tyingBox').keyup(function () {
    clearTimeout(typingTimer);
    typingTimer = setTimeout(function () {
        $("p.content").html(oldData);

I had the same issue, i realized i had deleted the default image that was in the folder just update the media missing, on the specific file

I dont know if this useful for you when you resize your page:

$(window).resize(function() {
       if(screen.width == window.innerWidth){
           alert("you are on normal page with 100% zoom");
       } else if(screen.width > window.innerWidth){
           alert("you have zoomed in the page i.e more than 100%");
       } else {
           alert("you have zoomed out i.e less than 100%");
       }
    });

I like to keep the original array and return a copy. This is a generic version:

public static <T> T[] reverse(T[] array) {
    T[] copy = array.clone();
    Collections.reverse(Arrays.asList(copy));
    return copy;
}

without keeping the original array:

public static <T> void reverse(T[] array) {
    Collections.reverse(Arrays.asList(array));
}

According to the Microsoft documentation, the TimeSpan structure exposes Hours, Minutes, Seconds, and Milliseconds as integer members. Maybe you want something like:

dateDifference.Hours.ToString() + " hrs, " + dateDifference.Minutes.ToString() + " mins, " + dateDifference.Seconds.ToString() + " secs"

I had the same issue with CakePHP 2.0.1

I tried using

header( 'HTTP/1.1 400 BAD REQUEST' );

and

$this->header( 'HTTP/1.1 400 BAD REQUEST' );

However, neither of these solved my issue.

I did eventually resolve it by using

$this->header( 'HTTP/1.1 400: BAD REQUEST' );

After that, no errors or warning from php / CakePHP.

*edit: In the last $this->header function call, I put a colon (:) between the 400 and the description text of the error.

A strong reference (which you will use in most cases) means that you want to "own" the object you are referencing with this property/variable. The compiler will take care that any object that you assign to this property will not be destroyed as long as you point to it with a strong reference. Only once you set the property to nil will the object get destroyed (unless one or more other objects also hold a strong reference to it).

In contrast, with a weak reference you signify that you don't want to have control over the object's lifetime. The object you are referencing weakly only lives on because at least one other object holds a strong reference to it. Once that is no longer the case, the object gets destroyed and your weak property will automatically get set to nil. The most frequent use cases of weak references in iOS are:

1. delegate properties, which are often referenced weakly to avoid retain cycles, and

2. subviews/controls of a view controller's main view because those views are already strongly held by the main view.

atomic vs. nonatomic refers to the thread safety of the getter and setter methods that the compiler synthesizes for the property. atomic (the default) tells the compiler to make the accessor methods thread-safe (by adding a lock before an ivar is accessed) and nonatomic does the opposite. The advantage of nonatomic is slightly higher performance. On iOS, Apple uses nonatomic for almost all their properties so the general advice is for you to do the same.

If you are using jQuery you can easily check the type of any element.

    function(elementID){    
    var type = $(elementId).attr('type');
    if(type == "text") //inputBox
     console.log("input text" + $(elementId).val().size());
   }

similarly you can check the other types and take appropriate action.

The proper JPA query format would be:

el.name IN :inclList

If you're using an older version of Hibernate as your provider you have to write:

el.name IN (:inclList)

but that is a bug (HHH-5126) (EDIT: which has been resolved by now).

I like lambda :)

 private void ClearTextBoxes()
 {
     Action<Control.ControlCollection> func = null;

     func = (controls) =>
         {
             foreach (Control control in controls)
                 if (control is TextBox)
                     (control as TextBox).Clear();
                 else
                     func(control.Controls);
         };

     func(Controls);
 }

Good luck!

You can simply cast strings to DateTime:

[DateTime]"2020-7-16"

or

[DateTime]"Jul-16"

or

$myDate = [DateTime]"Jul-16";

And you can format the resulting DateTime variable by doing something like this:

'{0:yyyy-MM-dd}' -f [DateTime]'Jul-16'

or

([DateTime]"Jul-16").ToString('yyyy-MM-dd')

or

$myDate = [DateTime]"Jul-16";
'{0:yyyy-MM-dd}' -f $myDate

private void replaceView(View oldV,View newV){
        ViewGroup par = (ViewGroup)oldV.getParent();
        if(par == null){return;}
        int i1 = par.indexOfChild(oldV);
        par.removeViewAt(i1);
        par.addView(newV,i1);
    }

By alphabetical-order I assume the order to be : A|a < B|b < C|c... Hope this is what @Nick is(or was) looking for and the answer follows the above assumption.

I would suggest to have a class implement compare method of Comparator-interface as :

public int compare(Object o1, Object o2) {
    return o1.toString().compareToIgnoreCase(o2.toString());
}

and from the calling method invoke the Arrays.sort method with custom Comparator as :

Arrays.sort(inputArray, customComparator);

Observed results: input Array : "Vani","Kali", "Mohan","Soni","kuldeep","Arun"

output(Alphabetical-order) is : Arun, Kali, kuldeep, Mohan, Soni, Vani

Output(Natural-order by executing Arrays.sort(inputArray) is : Arun, Kali, Mohan, Soni, Vani, kuldeep

Thus in case of natural ordering, [Vani < kuldeep] which to my understanding of alphabetical-order is not the thing desired.

for more understanding of natural and alphabetical/lexical order visit discussion here

The best and easiest way to clear a JLIST is:

myJlist.setListData(new String[0]);

As already mentioned its just a facade and it helps to switch between different logger implementation easily. For example if you want to use log4j implementation.

A sample code would looks like below.

If you use maven get the dependencies

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.6</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.5</version>
    </dependency>

Have the below in log4j.properties in location src/main/resources/log4j.properties

            log4j.rootLogger=DEBUG, STDOUT, file

            log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
            log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
            log4j.appender.STDOUT.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

            log4j.appender.file=org.apache.log4j.RollingFileAppender
            log4j.appender.file.File=mylogs.log
            log4j.appender.file.layout=org.apache.log4j.PatternLayout
            log4j.appender.file.layout.ConversionPattern=%d{dd-MM-yyyy HH:mm:ss} %-5p %c{1}:%L - %m%n

Hello world code below would prints in console and to a log file as per above configuration.

            import org.slf4j.Logger;
            import org.slf4j.LoggerFactory;

            public class HelloWorld {
              public static void main(String[] args) {
                Logger logger = LoggerFactory.getLogger(HelloWorld.class);
                logger.info("Hello World");
              }
            }

There is always sys.exit().

The system library in Python's core library has an exit function which is super handy when prototyping. The code would be along the lines of:

import sys

while True:
    selection = raw_input("U: Create User\nQ: Quit")
    if selection is "Q" or selection is "q":
        print("Quitting")
        sys.exit()
    if selection is "U" or selection is "u":
        print("User")
        #do_something()

Try this to get all the list at first, then your desired element (say the First in your case):

var desiredElementCompoundValueList = new List<YourType>();
dic.Values.ToList().ForEach( elem => 
{
   desiredElementCompoundValue.Add(elem.ComponentValue("Dep"));
});
var x = desiredElementCompoundValueList.FirstOrDefault();

To get directly the first element value without a lot of foreach iteration and variable assignment:

var desiredCompoundValue = dic.Values.ToList().Select( elem => elem.CompoundValue("Dep")).FirstOrDefault();

See the difference between the two approaches: in the first one you get the list through a ForEach, then your element. In the second you can get your value in a straight way.

Same result, different computation ;)

Your JavaScript would have to be defined within a PHP-parsed file.

For example, in index.php you could place

<?php
$time = time();
?>
<script>
    document.write(<?php echo $time; ?>);
</script>

You can create a backup device in server object, let us say

BDTEST

and then create a batch file contain following command

sqlcmd -S 192.168.1.25 -E -Q "BACKUP DATABASE dbtest TO BDTEST"

let us say with name

backup.bat

then you can call

backup.bat

in task scheduler according to your convenience

Already Answered here

You can't. If you want to change it, you need to use a list instead of a tuple.

Note that you could instead make a new tuple that has the new value as its first element.

public static void replaceFileString(String old, String new) throws IOException {
    String fileName = Settings.getValue("fileDirectory");
    FileInputStream fis = new FileInputStream(fileName);
    String content = IOUtils.toString(fis, Charset.defaultCharset());
    content = content.replaceAll(old, new);
    FileOutputStream fos = new FileOutputStream(fileName);
    IOUtils.write(content, new FileOutputStream(fileName), Charset.defaultCharset());
    fis.close();
    fos.close();
}

above is my implementation of Meriton's example that works for me. The fileName is the directory (ie. D:\utilities\settings.txt). I'm not sure what character set should be used, but I ran this code on a Windows XP machine just now and it did the trick without doing that temporary file creation and renaming stuff.

Java 8

We can make use of removeIf which takes a predicate to write a utility method as:

// computes the difference without modifying the sets
public static <T> Set<T> differenceJava8(final Set<T> setOne, final Set<T> setTwo) {
     Set<T> result = new HashSet<T>(setOne);
     result.removeIf(setTwo::contains);
     return result;
}

And in case we are still at some prior version then we can use removeAll as:

public static <T> Set<T> difference(final Set<T> setOne, final Set<T> setTwo) {
     Set<T> result = new HashSet<T>(setOne);
     result.removeAll(setTwo);
     return result;
}

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

Or if you have an array of [key, value] arrays, you can do:

[[1, 2], [3, 4]].inject({}) do |r, s|
  r.merge!({s[0] => s[1]})
end # => { 1 => 2, 3 => 4 }

It's possible to change default fonts, both for the axes and for other text, by adding the following lines to the startup.m file.

% Change default axes fonts.
set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize', 14)

% Change default text fonts.
set(0,'DefaultTextFontname', 'Times New Roman')
set(0,'DefaultTextFontSize', 14)

If you don't know if you have a startup.m file, run

which startup

to find its location. If Matlab says there isn't one, run

userpath

to know where it should be placed.

Replace the username and password with Integrated Security=SSPI;

So the connection string should be

<connectionStrings> 
<add name="NorthwindContex" 
   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" />

From the docs, "Note that from + size can not be more than the index.max_result_window index setting which defaults to 10,000". So my admittedly very ad-hoc solution is to just pass size: 10000 or 10,000 minus from if I use the from argument.

Note that following Matt's comment below, the proper way to do this if you have a larger amount of documents is to use the scroll api. I have used this successfully, but only with the python interface.

SELECT contactid, Count(*) 
FROM <YOUR_TABLE> WHERE flag in ('Volunteer','Uploaded')  
GROUP BY contactid 
HAVING count(*)>1;

I think you're running into problems because RedHat uses RPM for managing packages. Debian based systems use DEBs, which are managed with tools like apt.

Since you have master page and your control is in content place holder, Your control id will be generated different in client side. you need to do like...

var TestVar = document.getElementById('<%= txt_model_code.ClientID %>').value;

Javascript runs on client side and to get value you have to provide client id of your control

LoadLibrary does not do what you think it does. It loads the DLL into the memory of the current process, but it does not magically import functions defined in it! This wouldn't be possible, as function calls are resolved by the linker at compile time while LoadLibrary is called at runtime (remember that C++ is a statically typed language).

You need a separate WinAPI function to get the address of dynamically loaded functions: GetProcAddress.

Example

#include <windows.h>
#include <iostream>

/* Define a function pointer for our imported
 * function.
 * This reads as "introduce the new type f_funci as the type: 
 *                pointer to a function returning an int and 
 *                taking no arguments.
 *
 * Make sure to use matching calling convention (__cdecl, __stdcall, ...)
 * with the exported function. __stdcall is the convention used by the WinAPI
 */
typedef int (__stdcall *f_funci)();

int main()
{
  HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\Documents and Settings\\User\\Desktop\\test.dll");

  if (!hGetProcIDDLL) {
    std::cout << "could not load the dynamic library" << std::endl;
    return EXIT_FAILURE;
  }

  // resolve function address here
  f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "funci");
  if (!funci) {
    std::cout << "could not locate the function" << std::endl;
    return EXIT_FAILURE;
  }

  std::cout << "funci() returned " << funci() << std::endl;

  return EXIT_SUCCESS;
}

Also, you should export your function from the DLL correctly. This can be done like this:

int __declspec(dllexport) __stdcall funci() {
   // ...
}

As Lundin notes, it's good practice to free the handle to the library if you don't need them it longer. This will cause it to get unloaded if no other process still holds a handle to the same DLL.

In addition to the still very relevant answer of jujule, I find it quite important to also be aware of the implications of order_by() on distinct("field_name") queries. This is, however, a Postgres only feature!

If you are using Postgres and if you define a field name that the query should be distinct for, then order_by() needs to begin with the same field name (or field names) in the same sequence (there may be more fields afterward).

Note

When you specify field names, you must provide an order_by() in the QuerySet, and the fields in order_by() must start with the fields in distinct(), in the same order.

For example, SELECT DISTINCT ON (a) gives you the first row for each value in column a. If you don’t specify an order, you’ll get some arbitrary row.

If you want to e-g- extract a list of cities that you know shops in , the example of jujule would have to be adapted to this:

# returns an iterable Queryset of cities.
models.Shop.objects.order_by('city').values_list('city', flat=True).distinct('city')  

Using this HTML:

<div id="myElement" style="position: absolute">This stays at the top</div>

This is the javascript you want to use. It attaches an event to the window's scroll and moves the element down as far as you've scrolled.

$(window).scroll(function() {
    $('#myElement').css('top', $(this).scrollTop() + "px");
});

As pointed out in the comments below, it's not recommended to attach events to the scroll event - as the user scrolls, it fires A LOT, and can cause performance issues. Consider using it with Ben Alman's debounce/throttle plugin to reduce overhead.

There are no PowerShell-native commands for Base64 conversion - yet (as of PowerShell [Core] 7.1), but adding dedicated cmdlets has been suggested.
For now, direct use of .NET is needed.

Important:

• Base64 encoding is an encoding of binary data using bytes whose values are constrained to a well-defined 64-character subrange of the ASCII character set representing printable characters, devised at a time when sending arbitrary bytes was problematic, especially with the high bit set (byte values > 0x7f).

• Therefore, you must always specify explicitly what character encoding the Base64 bytes do / should represent.

Ergo:

• on converting TO Base64, you must first obtain a byte representation of the string you're trying to encode using the character encoding the consumer of the Base64 string expects.

• on converting FROM Base64, you must interpret the resultant array of bytes as a string using the same encoding that was used to create the Base64 representation.

Examples:

Note:

• The following examples convert to and from UTF-8 encoded strings:

• To convert to and from UTF-16LE ("Unicode") instead, substitute [Text.Encoding]::Unicode for [Text.Encoding]::UTF8

Convert TO Base64:

PS> [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes('Motörhead'))
TW90w7ZyaGVhZA==

Convert FROM Base64:

PS> [Text.Encoding]::Utf8.GetString([Convert]::FromBase64String('TW90w7ZyaGVhZA=='))
Motörhead
