This will may be the simplest answer one can find for the PCA including easily understandable steps. Let say we want to retain 2 principal dimensions from the 144 which provides maximum information.

Firstly, convert your 2-D array to a dataframe:

import pandas as pd

# Here X is your array of size (26424 x 144)
data = pd.DataFrame(X)

Then, there are two methods one can go with:

Method 1: Manual calculation

Step 1: Apply column standardization on X

from sklearn import preprocessing

scalar = preprocessing.StandardScaler()
standardized_data = scalar.fit_transform(data)

Step 2: Find Co-variance matrix S of original matrix X

sample_data = standardized_data
covar_matrix = np.cov(sample_data)

Step 3: Find eigen values and eigen vectors of S (here 2D, so 2 of each)

from scipy.linalg import eigh

# eigh() function will provide eigen-values and eigen-vectors for a given matrix.
# eigvals=(low value, high value) takes eigen value numbers in ascending order
values, vectors = eigh(covar_matrix, eigvals=(142,143))

# Converting the eigen vectors into (2,d) shape for easyness of further computations
vectors = vectors.T

Step 4: Transform the data

# Projecting the original data sample on the plane formed by two principal eigen vectors by vector-vector multiplication.

new_coordinates = np.matmul(vectors, sample_data.T)
print(new_coordinates.T)

This new_coordinates.T will be of size (26424 x 2) with 2 principal components.

Method 2: Using Scikit-Learn

Step 1: Apply column standardization on X

from sklearn import preprocessing

scalar = preprocessing.StandardScaler()
standardized_data = scalar.fit_transform(data)

Step 2: Initializing the pca

from sklearn import decomposition

# n_components = numbers of dimenstions you want to retain
pca = decomposition.PCA(n_components=2)

Step 3: Using pca to fit the data

# This line takes care of calculating co-variance matrix, eigen values, eigen vectors and multiplying top 2 eigen vectors with data-matrix X.
pca_data = pca.fit_transform(sample_data)

This pca_data will be of size (26424 x 2) with 2 principal components.

jqPlot is great. If your requirements are fairly "normal" and you just want to draw some charts, you're probably overwhelmed by the quantity of js charting options. Assuming you don't want to do hours of research, just go with jqPlot as it's probably your best bet. It covers most use cases for most people well. Some of the alternatives are specialised on a certain type of chart or built with a certain use case in mind.

You could parse the JSON to an object, then create your malformed JSON from the ajavscript object. This may not be the best performance-wise, tho.

Otherwise, if you only need to make very small changes to the string, just treat it as a string, and mangle it using standard javascript.

Like this:

Double foo = 123.456;
Integer bar = foo.intValue();

There is a lot of confusion around lambdas and closures, even in the answers to this StackOverflow question here. Instead of asking random programmers who learned about closures from practice with certain programming languages or other clueless programmers, take a journey to the source (where it all began). And since lambdas and closures come from Lambda Calculus invented by Alonzo Church back in the '30s before first electronic computers even existed, this is the source I'm talking about.

Lambda Calculus is the simplest programming language in the world. The only things you can do in it:?

• APPLICATION: Applying one expression to another, denoted f x.
  (Think of it as a function call, where f is the function and x is its only parameter)
• ABSTRACTION: Binds a symbol occurring in an expression to mark that this symbol is just a "slot", a blank box waiting to be filled with value, a "variable" as it were. It is done by prepending a Greek letter ? (lambda), then the symbolic name (e.g. x), then a dot . before the expression. This then converts the expression into a function expecting one parameter.
  For example: ?x.x+2 takes the expression x+2 and tells that the symbol x in this expression is a bound variable – it can be substituted with a value you supply as a parameter.
  Note that the function defined this way is anonymous – it doesn't have a name, so you can't refer to it yet, but you can immediately call it (remember application?) by supplying it the parameter it is waiting for, like this: (?x.x+2) 7. Then the expression (in this case a literal value) 7 is substituted as x in the subexpression x+2 of the applied lambda, so you get 7+2, which then reduces to 9 by common arithmetics rules.

So we've solved one of the mysteries:
lambda is the anonymous function from the example above, ?x.x+2.

function(x) { return x+2; }

and you can immediately apply it to some parameter like this:

(function(x) { return x+2; })(7)

or you can store this anonymous function (lambda) into some variable:

var f = function(x) { return x+2; }

which effectively gives it a name f, allowing you to refer to it and call it multiple times later, e.g.:

alert(  f(7) + f(10)  );   // should print 21 in the message box

But you didn't have to name it. You could call it immediately:

alert(  function(x) { return x+2; } (7)  );  // should print 9 in the message box

In LISP, lambdas are made like this:

(lambda (x) (+ x 2))

and you can call such a lambda by applying it immediately to a parameter:

(  (lambda (x) (+ x 2))  7  )

As I said, what the lambda abstraction does is binding a symbol in its subexpression, so that it becomes a substitutible parameter. Such a symbol is called bound. But what if there are other symbols in the expression? For example: ?x.x/y+2. In this expression, the symbol x is bound by the lambda abstraction ?x. preceding it. But the other symbol, y, is not bound – it is free. We don't know what it is and where it comes from, so we don't know what it means and what value it represents, and therefore we cannot evaluate that expression until we figure out what y means.

In fact, the same goes with the other two symbols, 2 and +. It's just that we are so familiar with these two symbols that we usually forget that the computer doesn't know them and we need to tell it what they mean by defining them somewhere, e.g. in a library or the language itself.

You can think of the free symbols as defined somewhere else, outside the expression, in its "surrounding context", which is called its environment. The environment might be a bigger expression that this expression is a part of (as Qui-Gon Jinn said: "There's always a bigger fish" ;) ), or in some library, or in the language itself (as a primitive).

This lets us divide lambda expressions into two categories:

• CLOSED expressions: every symbol that occurs in these expressions is bound by some lambda abstraction. In other words, they are self-contained; they don't require any surrounding context to be evaluated. They are also called combinators.
• OPEN expressions: some symbols in these expressions are not bound – that is, some of the symbols occurring in them are free and they require some external information, and thus they cannot be evaluated until you supply the definitions of these symbols.

You can CLOSE an open lambda expression by supplying the environment, which defines all these free symbols by binding them to some values (which may be numbers, strings, anonymous functions aka lambdas, whatever…).

And here comes the closure part:
The closure of a lambda expression is this particular set of symbols defined in the outer context (environment) that give values to the free symbols in this expression, making them non-free anymore. It turns an open lambda expression, which still contains some "undefined" free symbols, into a closed one, which doesn't have any free symbols anymore.

For example, if you have the following lambda expression: ?x.x/y+2, the symbol x is bound, while the symbol y is free, therefore the expression is open and cannot be evaluated unless you say what y means (and the same with + and 2, which are also free). But suppose that you also have an environment like this:

{  y: 3,
+: [built-in addition],
2: [built-in number],
q: 42,
w: 5  }

This environment supplies definitions for all the "undefined" (free) symbols from our lambda expression (y, +, 2), and several extra symbols (q, w). The symbols that we need to be defined are this subset of the environment:

{  y: 3,
+: [built-in addition],
2: [built-in number]  }

and this is precisely the closure of our lambda expression :>

In other words, it closes an open lambda expression. This is where the name closure came from in the first place, and this is why so many people's answers in this thread are not quite correct :P

Well, the corporate marketoids of Sun/Oracle, Microsoft, Google etc. are to blame, because that's what they called these constructs in their languages (Java, C#, Go etc.). They often call "closures" what are supposed to be just lambdas. Or they call "closures" a particular technique they used to implement lexical scoping, that is, the fact that a function can access the variables that were defined in its outer scope at the time of its definition. They often say that the function "encloses" these variables, that is, captures them into some data structure to save them from being destroyed after the outer function finishes executing. But this is just made-up post factum "folklore etymology" and marketing, which only makes things more confusing, because every language vendor uses its own terminology.

And it's even worse because of the fact that there's always a bit of truth in what they say, which does not allow you to easily dismiss it as false :P Let me explain:

If you want to implement a language that uses lambdas as first-class citizens, you need to allow them to use symbols defined in their surrounding context (that is, to use free variables in your lambdas). And these symbols must be there even when the surrounding function returns. The problem is that these symbols are bound to some local storage of the function (usually on the call stack), which won't be there anymore when the function returns. Therefore, in order for a lambda to work the way you expect, you need to somehow "capture" all these free variables from its outer context and save them for later, even when the outer context will be gone. That is, you need to find the closure of your lambda (all these external variables it uses) and store it somewhere else (either by making a copy, or by preparing space for them upfront, somewhere else than on the stack). The actual method you use to achieve this goal is an "implementation detail" of your language. What's important here is the closure, which is the set of free variables from the environment of your lambda that need to be saved somewhere.

It didn't took too long for people to start calling the actual data structure they use in their language's implementations to implement closure as the "closure" itself. The structure usually looks something like this:

Closure {
   [pointer to the lambda function's machine code],
   [pointer to the lambda function's environment]
}

and these data structures are being passed around as parameters to other functions, returned from functions, and stored in variables, to represent lambdas, and allowing them to access their enclosing environment as well as the machine code to run in that context. But it's just a way (one of many) to implement closure, not the closure itself.

As I explained above, the closure of a lambda expression is the subset of definitions in its environment that give values to the free variables contained in that lambda expression, effectively closing the expression (turning an open lambda expression, which cannot be evaluated yet, into a closed lambda expression, which can then be evaluated, since all the symbols contained in it are now defined).

Anything else is just a "cargo cult" and "voo-doo magic" of programmers and language vendors unaware of the real roots of these notions.

I hope that answers your questions. But if you had any follow-up questions, feel free to ask them in the comments, and I'll try to explain it better.

You are trying to copy the war file to a directory below webapps. The war file should be copied into the webapps directory.

Remove the mkdir command, and copy the war file like this:

COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

Tomcat will extract the war if autodeploy is turned on.

Using LINQ:

IEnumerable<ModelError> allErrors = ModelState.Values.SelectMany(v => v.Errors);

The TextBox has a property called ReadOnly. If you set that property to true then the TextBox will still be able to scroll but the user wont be able to change the value.

You can only use one color but as many images as you want, here is the format:

background: [ <bg-layer> , ]* <final-bg-layer>

<bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2}

<final-bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2} || <background-color>

or background: url(image1.png) center bottom no-repeat, url(image2.png) left top no-repeat;

If you need more colors, make an image of a solid color and use it. I know it’s not what you want to hear, but I hope it helps.

The format is from http://www.css3.info/preview/multiple-backgrounds/

JS Fiddle Example

$('#userNav').change(function() {
window.location = $(':selected',this).attr('href')
});




<select id="userNav">
<option></option>
<option href="http://google.com">Goolge</option>
<option href="http://duckduckgo.com">Go Go duck</option>
</select>

This works for the href in an option that is selected

Use the readlink utility from the coreutils package.

MY_PATH=$(readlink -f "$0")

Would something like

(pattern.*?(pattern))*

work for you?

Edit:

The problem with this is that it uses the non-greedy operator *?, which can require an awful lot of backtracking along the string instead of just looking at each letter once. What this means for you is that this could be slow for large gaps.

This works for me on the Northwind sample DB, note that SearchLetter has 2 characters to it and SearchLetter also has to be declared for this to run:

declare @SearchLetter2 char(2)
declare @SearchLetter char(1)
Set @SearchLetter = 'A'
Set @SearchLetter2 = @SearchLetter+'%'
select * from Customers where ContactName like @SearchLetter2 and Region='WY'

Expanding on the accepted answer, if the input is:

1,NYC
2,ABQ
...

you will still be able to apply the same logic, like this:

#include <fstream>

std::ifstream infile("thefile.txt");
if (infile.is_open()) {
    int number;
    std::string str;
    char c;
    while (infile >> number >> c >> str && c == ',')
        std::cout << number << " " << str << "\n";
}
infile.close();

let url = URL(string: "url")!
var request = URLRequest(url: url)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")

request.httpMethod = "POST"



let postString = "ChangeAccordingtoyourdata=\(paramOne)&ChangeAccordingtoyourdata2=\(paramTwo)"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {                                                 // check for fundamental networking error
        print("error=\(error)")
        return
    }

    if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
        print("statusCode should be 200, but is \(httpStatus.statusCode)")
        print("response = \(response)")

        SVProgressHUD.showError(withStatus: "Request has not submitted successfully.\nPlease try after some time")
    }

    let responseString = String(data: data, encoding: .utf8)
    print("responseString = \(responseString)")

    SVProgressHUD.showSuccess(withStatus: "Request has submitted successfully.\nPlease wait for a while")
    DispatchQueue.main.async {



    // enter code

    }

}
task.resume()

eReminderTime.setText( "" + selectedHour + ":" + selectedMinute);

Your missing a + between "" and selected hour, setText methods only take a single string, so you need to concatenate all the parts (the first quotes are likely unnecessary).

eReminderTime.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);
            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(AddReminder.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    eReminderTime.setText( selectedHour + ":" + selectedMinute);
                }
            }, hour, minute, true);//Yes 24 hour time
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();

        }
    });

That should fix your second error, you weren't providing the last parameter. TimePickerDialog Constructors

You should define the function textcolor before. Because textcolor is not a standard function in C.

void textcolor(unsigned short color) {
    HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hcon,color);
}

and you are done ....

There is nothing that char array gives you vs String unless you clean it up manually after use, and I haven't seen anyone actually doing that. So to me the preference of char[] vs String is a bit exaggerated.

Take a look at the _{widely used} Spring Security library here and ask yourself - are Spring Security guys incompetent or char[] passwords just don't make much sense. When some nasty hacker grabs memory dumps of your RAM be sure s/he'll get all the passwords even if you use sophisticated ways to hide them.

However, Java changes all the time, and some scary features like String Deduplication feature of Java 8 might intern String objects without your knowledge. But that's a different conversation.

If you work with Visual Studio then it is pretty easy to get persistable settings. Right click on the project in Solution Explorer and choose Properties. Select the Settings tab and click on the hyperlink if settings doesn't exist.

Use the Settings tab to create application settings. Visual Studio creates the files Settings.settings and Settings.Designer.settings that contain the singleton class Settings inherited from ApplicationSettingsBase. You can access this class from your code to read/write application settings:

Properties.Settings.Default["SomeProperty"] = "Some Value";
Properties.Settings.Default.Save(); // Saves settings in application configuration file

This technique is applicable both for console, Windows Forms, and other project types.

Note that you need to set the scope property of your settings. If you select Application scope then Settings.Default.<your property> will be read-only.

There is a W3C specification defining possible date strings that should be parseable by any browser (including Firefox and Safari):

Year:

Year and month:
   YYYY-MM (e.g., 1997-07)
Complete date:
   YYYY-MM-DD (e.g., 1997-07-16)

Complete date plus hours, minutes and seconds:
   YYYY-MM-DDThh:mm:ssTZD (e.g., 1997-07-16T19:20:30+01:00)
Complete date plus hours, minutes, seconds and a decimal fraction of a
second
   YYYY-MM-DDThh:mm:ss.sTZD (e.g., 1997-07-16T19:20:30.45+01:00)

where

YYYY = four-digit year
MM   = two-digit month (01=January, etc.)
DD   = two-digit day of month (01 through 31)
hh   = two digits of hour (00 through 23) (am/pm NOT allowed)
mm   = two digits of minute (00 through 59)
ss   = two digits of second (00 through 59)
s    = one or more digits representing a decimal fraction of a second
TZD  = time zone designator (Z or +hh:mm or -hh:mm)

According to YYYY-MM-DDThh:mmTZD, the example 2010-07-15 11:54:21 has to be converted to either 2010-07-15T11:54:21Z or 2010-07-15T11:54:21+02:00 (or with any other timezone).

Here is a short example showing the results of each variant:

const oldDateString = '2010-07-15 11:54:21'
const newDateStringWithoutTZD = '2010-07-15T11:54:21Z'
const newDateStringWithTZD = '2010-07-15T11:54:21+02:00'
document.getElementById('oldDateString').innerHTML = (new Date(oldDateString)).toString()
document.getElementById('newDateStringWithoutTZD').innerHTML = (new Date(newDateStringWithoutTZD)).toString()
document.getElementById('newDateStringWithTZD').innerHTML = (new Date(newDateStringWithTZD)).toString()

div {
  padding: 10px;
}

<div>
  <strong>Old Date String</strong>
  <br>
  <span id="oldDateString"></span>
</div>
<div>
  <strong>New Date String (without Timezone)</strong>
  <br>
  <span id="newDateStringWithoutTZD"></span>
</div>
<div>
  <strong>New Date String (with Timezone)</strong>
  <br>
  <span id="newDateStringWithTZD"></span>
</div>

If you are counting letters, the above solution will fail for some unicode symbols. For example for these 5 characters sample.length() will return 6 instead of 5:

String sample = "\u760c\u0444\u03b3\u03b5\ud800\udf45"; // ???e

The codePointCount function was introduced in Java 1.5 and I understand gives better results for glyphs etc

sample.codePointCount(0, sample.length()) // returns 5

    var regex=/^([0-9]{2,4})-([0-1][0-9])-([0-3][0-9]) (?:([0-2][0-9]):([0-5][0-9]):([0-5][0-9]))?$/;
    var parts=timestamp.replace(regex,"$1 $2 $3 $4 $5 $6").split(' ');
    return new Date(parts[0],parts[1]-1,parts[2],parts[3],parts[4],parts[5]);
  }

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

Just came to know about this when I was searching for a solution to a similar problem. SQL has a new keyword called CONTAINS you can use that. For more details see http://msdn.microsoft.com/en-us/library/ms187787.aspx

1. assign

   • assign is a default property attribute
   • assign is a property attribute tells the compiler how to synthesize the property’s setter implementation

2. copy:

   • copy is required when the object is mutable
   • copy returns an object which you must explicitly release (e.g., in dealloc) in non-garbage collected environments
   • you need to release the object when finished with it because you are retaining the copy

3. retain:

   • specifies the new value should be sent “-retain” on assignment and the old value sent “-release”
   • if you write retain it will auto work like strong
   • Methods like “alloc” include an implicit “retain”

        SET @query=CONCAT('SELECT COUNT(*) INTO @rcount FROM  ',tableName,' WHERE ',columnName,'  like ''',newUniqueValue,'''');
        PREPARE stmt FROM  @query;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;
    IF @rcount = 0 THEN
            SET uniqueValue = @newUniqueValue ;
        END IF ;
    END WHILE ;
    SELECT uniqueValue;
    END$$

DELIMITER ;

And call the stored procedure as GenerateUniqueValue('tableName','columnName'). This will give you a 8 digit unique character everytime.

You want

#content div:first-child {
/*css*/
}

Try this

df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

This works for me

• Context Menu key (one one with the menu on it, next to the right Windows key)
• Then choose "Resolve" from the menu. That can be done by pressing "s".

Do not set the background-color inside the print stylesheet. Just set the attribute in the normal css file and it works fine :)

You can use tf.pack (tf.stack in TensorFlow 1.0.0) method for this purpose. Here is how to pack a random image of type numpy.ndarray into a Tensor:

import numpy as np
import tensorflow as tf
random_image = np.random.randint(0,256, (300,400,3))
random_image_tensor = tf.pack(random_image)
tf.InteractiveSession()
evaluated_tensor = random_image_tensor.eval()

UPDATE: to convert a Python object to a Tensor you can use tf.convert_to_tensor function.

If you are using RestTemplateBuilder may be the usual thing wouldn't work. You need to add this in your test class along with when(condition).

@Before    
public void setup() {        
     ReflectionTestUtils.setField(service, "restTemplate", restTemplate);    
}

I had to add an older jdk on my project.

Right button on Project folder > Properties > Java Build Path > Libraries > Add Library > JRE System Library

In case you don't have the package for jdk8, download the jdk that some user mentioned above (http://download.oracle.com/otn-pub/java/jdk/8u172-b11/a58eab1ec242421181065cdc37240b08/jdk-8u172-windows-x64.exe) and click on "Installed JREs" and search for the directory you downloaded the jdk8.

Then click on Finish.

Remove the apache server and add again.

The magic is done ;)

The reduce function also works

import operator
h=['a','b','c','d']
reduce(operator.add, h)
'abcd'

1.Function Overloading is when multiple function with same name exist in a class. Function Overriding is when function have same prototype in base class as well as derived class.

2.Function Overloading can occur without inheritance. Function Overriding occurs when one class is inherited from another class.

3.Overloaded functions must differ in either number of parameters or type of parameters should be different. In Overridden function parameters must be same.

For more detail you can visit below link where you get more information about function overloading and overriding in c++ https://googleweblight.com/i?u=https://www.geeksforgeeks.org/function-overloading-vs-function-overriding-in-cpp/&hl=en-IN

        $services = $this->Service->find('all', array(
            'limit' =>4,
            'fields' => array('Service.*','ServiceImage.*'),
            'joins' => array(
                array(
                        'table' => 'services_images',
                        'alias' => 'ServiceImage',
                        'type' => 'INNER',
                        'conditions' => array(
                        'ServiceImage.service_id' =>'Service.id'
                        )
                    ),
                ),
            )
        );

It goges to array is null.

If it is native code, you can disassemble it. But you wont see the original code as writte by the programmer. You will see the code produces by the compiler (assembler). This code is possibly optimized and although it is semantically equivalent, it can be much harder to read than normal ASM.

If it is bytecode (MSIL or javabytecode), there are decompiler which can product pretty good sourcecode. For .net, this would be reflector.

You can't pass parameters like this - the success object maps to an anonymous function with one parameter and that's the received data. Create a function outside of the for loop which takes (data, i) as parameters and perform the code there:

function image_link(data, i) {
   $(data).find("a:contains(.jpg)").each(function(){                                
       new Image().src = url[i] + $(this).attr("href");
   }
}
...
success: function(data){
    image_link(data, i)
}

Additional comment. Yes this works:

    sed 's/\"//g' infile.txt  > outfile.txt

(however with batch gnu sed, will just print to screen)

In batch scripting (GNU SED), this was needed:

    sed 's/\x22//g' infile.txt  > outfile.txt

If you are using Spring Framework then there is a MediaType class for common content types:

MediaType.TEXT_HTML 
MediaType.TEXT_PLAIN 
MediaType.TEXT_XML 
MediaType.APPLICATION_JSON 
MediaType.IMAGE_JPEG 
...

you just need to divide the Date Time stamp by 1000 like:

var a = 1437203995000;
a = (a)/1000;

org.springframework.core.io.Resource is part of spring-core-<version>.jar

But this lib is already in your lib folder. So I guess it is just a Deployment Problem. -- Try to clean your server and redeploy your application.

You can use .is(':visible')

Selects all elements that are visible.

For example:

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

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

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

Live example:

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

#selectDiv {_x000D_
  display: none;  _x000D_
}

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

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

You can use this command,

adb shell dumpsys activity

You can find current activity name in activity stack.

You should use the class name like this

$(document).ready(function(){
    $('input.addCheck').prop('checked',true);
});

Try Using this a live demo

The Array.newInstance(Class<?> componentType, int length) method is to be used to create an array with dynamically length.

Multi-dimensional arrays can be created similarly with the Array.newInstance(Class<?> componentType, int... dimensions) method.

you can probably ping the server via ajax inside javascript. The php file might look something like:

<?php
session_start();
$id = session_id();
echo $id;
?>

This will return you the current session id. Was this what you were looking for.

Here is an extension method that overloads the AppendText method with a color parameter:

public static class RichTextBoxExtensions
{
    public static void AppendText(this RichTextBox box, string text, Color color)
    {
        box.SelectionStart = box.TextLength;
        box.SelectionLength = 0;

        box.SelectionColor = color;
        box.AppendText(text);
        box.SelectionColor = box.ForeColor;
    }
}

And this is how you would use it:

var userid = "USER0001";
var message = "Access denied";
var box = new RichTextBox
              {
                  Dock = DockStyle.Fill,
                  Font = new Font("Courier New", 10)
              };

box.AppendText("[" + DateTime.Now.ToShortTimeString() + "]", Color.Red);
box.AppendText(" ");
box.AppendText(userid, Color.Green);
box.AppendText(": ");
box.AppendText(message, Color.Blue);
box.AppendText(Environment.NewLine);

new Form {Controls = {box}}.ShowDialog();

Note that you may notice some flickering if you're outputting a lot of messages. See this C# Corner article for ideas on how to reduce RichTextBox flicker.

The onclick attribute on your anchor tag is going to call a client-side function. (This is what you would use if you wanted to call a javascript function when the link is clicked.)

What you want is a server-side control, like the LinkButton:

<asp:LinkButton ID="lnkTutorial" runat="server" Text="Tutorial" OnClick="displayTutorial_Click"/>

This has an OnClick attribute that will call the method in your code behind.

Looking further into your code, it looks like you're just trying to open a different tutorial based on access level of the user. You don't need an event handler for this at all. A far better approach would be to just set the end point of your LinkButton control in the code behind.

protected void Page_Load(object sender, EventArgs e)
{
    userinfo = (UserInfo)Session["UserInfo"];

    if (userinfo.user == "Admin")
    {
        lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
    }
    else
    {
        lnkTutorial.PostBackUrl = "help/UserTutorial.html";
    }
}

Really, it would be best to check that you actually have a user first.

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["UserInfo"] != null && ((UserInfo)Session["UserInfo"]).user == "Admin")
    {
        lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
    }
    else
    {
        lnkTutorial.PostBackUrl = "help/UserTutorial.html";
    }
}

Use a DateFormat. In an internationalized application, use the format provide by getInstance. If you want to explicitly control the format, create a new SimpleDateFormat yourself.

I used the onscroll event at the element with the scrollbar. When triggered in IE, I added the following validation:

onscroll="if (document.activeElement==this) ignoreHideOptions()"

We do this kind of XML parsing all the time. The key is defining where the parsing method will leave the reader on exit. If you always leave the reader on the next element following the element that was first read then you can safely and predictably read in the XML stream. So if the reader is currently indexing the <Account> element, after parsing the reader will index the </Accounts> closing tag.

The parsing code looks something like this:

public class Account
{
    string _accountId;
    string _nameOfKin;
    Statements _statmentsAvailable;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read node attributes
        _accountId = reader.GetAttribute( "accountId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                switch( reader.Name )
                {
                    // Read element for a property of this class
                    case "NameOfKin":
                        _nameOfKin = reader.ReadElementContentAsString();
                        break;

                    // Starting sub-list
                case "StatementsAvailable":
                    _statementsAvailable = new Statements();
                    _statementsAvailable.Read( reader );
                    break;

                    default:
                        reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }       
    }
}

The Statements class just reads in the <StatementsAvailable> node

public class Statements
{
    List<Statement> _statements = new List<Statement>();

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();
        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                if( reader.Name == "Statement" )
                {
                    var statement = new Statement();
                    statement.ReadFromXml( reader );
                    _statements.Add( statement );               
                }
                else
                {
                    reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }
    }
}

The Statement class would look very much the same

public class Statement
{
    string _satementId;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read noe attributes
        _statementId = reader.GetAttribute( "statementId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {           
            ....same basic loop
        }       
    }
}

I like to simplify the code without using conditional operators in such cases:

TEMP=/mnt/silo/bin
[[ ${PATH} =~ ${TEMP} ]] || PATH=$PATH:$TEMP

Being au fait with patterns as defined by (say) the GOF book, and naming objects after these gets me a long way in naming classes, organising them and communicating intent. Most people will understand this nomenclature (or at least a major part of it).

Building on couple of the above answers, you could do this:

<button onclick="location.href='@Url.Action("ActionName", "ControllerName")'" />

Something like this:

firstList.AddRange (secondList);

Or, you can use the 'Union' extension method that is defined in System.Linq. With 'Union', you can also specify a comparer, which can be used to specify whether an item should be unioned or not.

Like this:

List<int> one = new List<int> { 1, 2, 3, 4, 5 };
List<int> second=new List<int> { 1, 2, 5, 6 };

var result = one.Union (second, new EqComparer ());

foreach( int x in result )
{
    Console.WriteLine (x);
}
Console.ReadLine ();

#region IEqualityComparer<int> Members
public class EqComparer : IEqualityComparer<int>
{
    public bool Equals( int x, int y )
    {
        return x == y;
    }

    public int GetHashCode( int obj )
    {
        return obj.GetHashCode ();
    }
}
#endregion

%~dp0 - return the path from where script executed

But, important to know also below one:

%CD% - return the current path in runtime, for example if you get into other folders using "cd folder1", and then "cd folder2", it will return the full path until folder2 and not the original path where script located

Well I'm not getting the "last value" in a table, I'm getting the Last value per financial instrument. It's not the same but I guess it is relevant for some that are looking to look up on "how it is done now". I also used RowNumber() and CTE's and before that to simply take 1 and order by [column] desc. however we nolonger need to...

I am using SQL server 2017, we are recording all ticks on all exchanges globally, we have ~12 billion ticks a day, we store each Bid, ask, and trade including the volumes and the attributes of a tick (bid, ask, trade) of any of the given exchanges.

We have 253 types of ticks data for any given contract (mostly statistics) in that table, the last traded price is tick type=4 so, when we need to get the "last" of Price we use :

select distinct T.contractId,
LAST_VALUE(t.Price)over(partition by t.ContractId order by created ROWS BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING)
from [dbo].[Tick] as T
where T.TickType=4

You can see the execution plan on my dev system it executes quite efficient, executes in 4 sec while the exchange import ETL is pumping data into the table, there will be some locking slowing me down... that's just how live systems work.

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

You have a character = STQ8QGpaM4CU6149665!7084880820, and you have a another column = 7084880820.

If you want to get only this in excel using the formula: STQ8QGpaM4CU6149665!, use this:

=REPLACE(H11,SEARCH(J11,H11),LEN(J11),"")

H11 is an old character and for starting number use search option then for no of character needs to replace use len option then replace to new character. I am replacing this to blank.

Password changes are handled by the subversion server administrator. As a user there is no password change option.

Check with your server admin.

If you are the admin, find your SVN Server installation. If you don't know where it is, it could be listed in Start->Programs, running under services in Start->Control Panel->Services or it could be listed under C:\Program Files.

The SVN Server should have an application to run to add/change/delete authentication and users.

I don't know of Google voice, but using the javaScript speech SpeechSynthesisUtterance, you can add a click event to the element you are reference to. eg:

const listenBtn = document.getElementById('myvoice');

listenBtn.addEventListener('click', (e) => {
  e.preventDefault();

  const msg = new SpeechSynthesisUtterance(
    "Hello, hope my code is helpful"
  );
  window.speechSynthesis.speak(msg);

});

<button type="button" id='myvoice'>Listen to me</button>

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

//Runs function after x seconds

public static func runThisAfterDelay(seconds: Double, after: @escaping () -> Void) {

a += b is shorthand for a = a +b which means:

Use jQuery....I know you say you're trying to teach someone javascript, but teach him a cleaner technique... for instance, I could:

<select id="navigation">
    <option value="unit_01.htm">Unit 1</option>
    <option value="#5.2">Bookmark 2</option>
</select>

And with a little jQuery, you could do:

$("#navigation").change(function()
{
    document.location.href = $(this).val();
});

Unobtrusive, and with clean separation of logic and UI.

If nginx_ajp_module is used, try adding ajp_read_timeout 10m; in nginx.conf file.

Is not possbile!

The only way is to obfuscate javascript or minify your javascript which makes it hard for the end user to reverse engineer. however its not impossible to reverse engineer.

If you don't pass any argument then even in that case args gets initialized but without any item/element. Try the following one, you will get the same effect:

 
public static void main(String[] args) throws InterruptedException {
        String [] dummy= new String [] {};
        if(dummy[0] == null)
        {
            System.out.println("Proper Usage is: java program filename");
            System.exit(0);
        }

    }

TL:DR
row lock = A$5
column lock = $A5
Both = $A$5

Below are examples of how to use the Excel lock reference $ when creating your formulas

To prevent increments when moving from one row to another put the $ after the column letter and before the row number. e.g. A$5

To prevent increments when moving from one column to another put the $ before the row number. e.g. $A5

To prevent increments when moving from one column to another or from one row to another put the $ before the row number and before the column letter. e.g. $A$5

Using the lock reference will also prevent increments when dragging cells over to duplicate calculations.

for more extendability for large scale apps use oop style with encapsulated fields.

Simple way :-

  class Fruit implements JsonSerializable {

        private $type = 'Apple', $lastEaten = null;

        public function __construct() {
            $this->lastEaten = new DateTime();
        }

        public function jsonSerialize() {
            return [
                'category' => $this->type,
                'EatenTime' => $this->lastEaten->format(DateTime::ISO8601)
            ];
        }
    }

echo json_encode(new Fruit()); //which outputs:

{"category":"Apple","EatenTime":"2013-01-31T11:17:07-0500"}

I have tried everything but could not make it work. Finally I have used pyenv and it worked directly like a charm.

So having homebrew installed, juste do:

brew install pyenv
pyenv install 3.6.5

to manage virtualenvs:

brew install pyenv-virtualenv
pyenv virtualenv 3.6.5 env_name

See pyenv and pyenv-virtualenv for more info.

EDIT (2019/03/19)

I have found using the pyenv-installer easier than homebrew to install pyenv and pyenv-virtualenv direclty:

curl https://pyenv.run | bash

To manage python version, either globally:

pyenv global 3.6.5

or locally in a given directory:

pyenv local 3.6.5

If you want to match an expression starting with [ and ending with ], use \[[^\]]*\].

For rows you can simply use wc -l file

-l stands for total line

for columns uou can simply use head -1 file | tr ";" "\n" | wc -l

Explanation
head -1 file
Grabbing the first line of your file, which should be the headers, and sending to it to the next cmd through the pipe
| tr ";" "\n"

tr stands for translate.
It will translate all ; characters into a newline character.
In this example ; is your delimiter.

Then it sends data to next command.

wc -l
Counts the total number of lines.

This should work

function updatePostID(val)
{
    document.getElementById('PostID').value = val;

    //and probably call document.forms[0].submit();
}

Then have a hidden field or other control for the PostID

@Html.Hidden("PostID", Model.addcomment.PostID)
//OR
@Html.HiddenFor(model => model.addcomment.PostID)

This kind of conversion is actually suprisingly unintuitive in Java

Take for example a following string : "100.00"

C : a simple standard library function at least since 1971 (Where did the name `atoi` come from?)

int i = atoi(decimalstring);

Java : mandatory passage by Double (or Float) parse, followed by a cast

int i = (int)Double.parseDouble(decimalstring);

Java sure has some oddities up it's sleeve

OpenGL is bundled with Visual Studio. You just need to install GLUT package (freeglut would be fine), which can be found in NuGet.

Open your solution, click TOOLS->NuGet Package Manager->Package Manager Console to open a NuGet console, type Install-Package freeglut.

For VS 2013, use nupengl.core package instead.

It's 2020 now. Use VCPKG.

 @hash{@array} = (1) x @array;

It's a hash slice, a list of values from the hash, so it gets the list-y @ in front.

From the docs:

If you're confused about why you use an '@' there on a hash slice instead of a '%', think of it like this. The type of bracket (square or curly) governs whether it's an array or a hash being looked at. On the other hand, the leading symbol ('$' or '@') on the array or hash indicates whether you are getting back a singular value (a scalar) or a plural one (a list).

Try setting the type of your parameter to [bool]:

param
(
    [int]$Turn = 0
    [bool]$Unity = $false
)

switch ($Unity)
{
    $true { "That was true."; break }
    default { "Whatever it was, it wasn't true."; break }
}

This example defaults $Unity to $false if no input is provided.

Usage

.\RunScript.ps1 -Turn 1 -Unity $false

Yes, it's possible. Provided that you put your files in a public folder, you can get any file in a folder by this URL:

                    System.out.println(count += 2);
                    common.wait();
                } catch (InterruptedException e) {

IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm.

This event handler is called when new instance of the UserForm is created. In this even handler u can initialize the private members of UserForm1 class.

Example:

Standard module code:

Option Explicit

Public Sub Main()
  Dim myUserForm As UserForm1

  Set myUserForm = New UserForm1
  myUserForm.Show

End Sub

User form code:

Option Explicit

Private m_initializationDate As Date

Private Sub UserForm_Initialize()
  m_initializationDate = VBA.DateTime.Date
  MsgBox "Hi from UserForm_Initialize event handler.", vbInformation
End Sub

DateTime dt1 = DateTime.Parse(maskedTextBox1.Text);
DateTime dt2 = DateTime.Parse(maskedTextBox2.Text);
TimeSpan span = dt2 - dt1;
int ms = (int)span.TotalMilliseconds;

Since raising an key error if one of keys is missing is a reasonable thing to do, we can even not check for it and get it as single as that:

def get_dict(d, kl):
  cur = d[kl[0]]
  return get_dict(cur, kl[1:]) if len(kl) > 1 else cur

db.messages.find( { headers : { From: "[email protected]" } } )

This queries for documents where headers equals { From: ... }, i.e. contains no other fields.

db.messages.find( { 'headers.From': "[email protected]" } )

This only looks at the headers.From field, not affected by other fields contained in, or missing from, headers.

Dot-notation docs

I don't believe there's anything built-in for this. It's made tricky by the fact that it's rare for a single line to change several times without the rest of the file changing substantially too, so you'll tend to end up with the line numbers changing a lot.

If you're lucky enough that the line always has some identifying characteristic, e.g. an assignment to a variable whose name never changed, you could use the regex choice for git blame -L. For example:

git blame -L '/variable_name *= */',+1

But this only finds the first match for that regex, so if you don't have a good way of matching the line, it's not too helpful.

You could hack something up, I suppose. I don't have time to write out code just now, but... something along these lines. Run git blame -n -L $n,$n $file. The first field is the previous commit touched, and the second field is the line number in that commit, since it could've changed. Grab those, and run git blame -n $n,$n $commit^ $file, i.e. the same thing starting from the commit before the last time the file was changed.

(Note that this will fail you if the last commit that changed the line was a merge commit. The primary way this could happen if the line was changed as part of a merge conflict resolution.)

Edit: I happened across this mailing list post from March 2011 today, which mentions that tig and git gui have a feature that will help you do this. It looks like the feature has been considered, but not finished, for git itself.

I suppose it's reasonable to want this behavior in some cases, but I would argue that code not triggering a form submission should (always) be the default behavior. Suppose you want to catch a form's submission with

$("form").submit(function(e){
    e.preventDefault();
});

and then do some validation on the input. If code could trigger submit handlers, you could never include

$("form").submit()

inside this handler because it would result in an infinite loop (the SAME handler would be called, prevent the submission, validate, and resubmit). You need to be able to manually submit a form inside a submit handler without triggering the same handler.

I realize this doesn't ANSWER the question directly, but there are lots of other answers on this page about how this functionality can be hacked, and I felt that this needed to be pointed out (and it's too long for a comment).

import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateTest {

    public static void main(String[] args) {
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        Date date = new Date(timestamp.getTime());

        // S is the millisecond
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy' 'HH:mm:ss:S");

        System.out.println(simpleDateFormat.format(timestamp));
        System.out.println(simpleDateFormat.format(date));
    }
}

Judging from your example, shouldn't it be {% url myproject.login.views.login_view %} and end of story? (replace myproject with your actual project name)

One reason to use object over iframe is that object re-sizes the embedded content to fit the object dimensions. most notable on safari in iPhone 4s where screen width is 320px and the html from the embedded URL may set dimensions greater.

Another alternative.

The OP asked a way to use a callback. In this case he was referring specifically to a function that process an event (in his example: a click event), which shall be treated as the accepted answer from @serginho suggests: with @Output and EventEmitter.

However, there is a difference between a callback and an event: With a callback your child component can retrieve some feedback or information from the parent, but an event only can inform that something happened without expect any feedback.

There are use cases where a feedback is necessary, ex. get a color, or a list of elements that the component needs to handle. You can use bound functions as some answers have suggested, or you can use interfaces (that's always my preference).

Example

Let's suppose you have a generic component that operates over a list of elements {id, name} that you want to use with all your database tables that have these fields. This component should:

• retrieve a range of elements (page) and show them in a list
• allow remove an element
• inform that an element was clicked, so the parent can take some action(s).
• allow retrieve the next page of elements.

Child Component

Using normal binding we would need 1 @Input() and 3 @Output() parameters (but without any feedback from the parent). Ex. <list-ctrl [items]="list" (itemClicked)="click($event)" (itemRemoved)="removeItem($event)" (loadNextPage)="load($event)" ...>, but creating an interface we will need only one @Input():

import {Component, Input, OnInit} from '@angular/core';

export interface IdName{
  id: number;
  name: string;
}

export interface IListComponentCallback<T extends IdName> {
    getList(page: number, limit: number): Promise< T[] >;
    removeItem(item: T): Promise<boolean>;
    click(item: T): void;
}

@Component({
    selector: 'list-ctrl',
    template: `
      <button class="item" (click)="loadMore()">Load page {{page+1}}</button>
      <div class="item" *ngFor="let item of list">
          <button (click)="onDel(item)">DEL</button>
          <div (click)="onClick(item)">
            Id: {{item.id}}, Name: "{{item.name}}"
          </div>
      </div>
    `,
    styles: [`
      .item{ margin: -1px .25rem 0; border: 1px solid #888; padding: .5rem; width: 100%; cursor:pointer; }
      .item > button{ float: right; }
      button.item{margin:.25rem;}
    `]
})
export class ListComponent implements OnInit {
    @Input() callback: IListComponentCallback<IdName>; // <-- CALLBACK
    list: IdName[];
    page = -1; 
    limit = 10;

    async ngOnInit() {
      this.loadMore();
    }
    onClick(item: IdName) {
      this.callback.click(item);   
    }
    async onDel(item: IdName){ 
        if(await this.callback.removeItem(item)) {
          const i = this.list.findIndex(i=>i.id == item.id);
          this.list.splice(i, 1);
        }
    }
    async loadMore(){
      this.page++;
      this.list = await this.callback.getList(this.page, this.limit); 
    }
}

Parent Component

Now we can use the list component in the parent.

import { Component } from "@angular/core";
import { SuggestionService } from "./suggestion.service";
import { IdName, IListComponentCallback } from "./list.component";

type Suggestion = IdName;

@Component({
  selector: "my-app",
  template: `
    <list-ctrl class="left" [callback]="this"></list-ctrl>
    <div class="right" *ngIf="msg">{{ msg }}<br/><pre>{{item|json}}</pre></div>
  `,
  styles:[`
    .left{ width: 50%; }
    .left,.right{ color: blue; display: inline-block; vertical-align: top}
    .right{max-width:50%;overflow-x:scroll;padding-left:1rem}
  `]
})
export class ParentComponent implements IListComponentCallback<Suggestion> {
  msg: string;
  item: Suggestion;

  constructor(private suggApi: SuggestionService) {}

  getList(page: number, limit: number): Promise<Suggestion[]> {
    return this.suggApi.getSuggestions(page, limit);
  }
  removeItem(item: Suggestion): Promise<boolean> {
    return this.suggApi.removeSuggestion(item.id)
      .then(() => {
        this.showMessage('removed', item);
        return true;
      })
      .catch(() => false);
  }
  click(item: Suggestion): void {
    this.showMessage('clicked', item);
  }
  private showMessage(msg: string, item: Suggestion) {
    this.item = item;
    this.msg = 'last ' + msg;
  }
}

Note that the <list-ctrl> receives this (parent component) as the callback object. One additional advantage is that it's not required to send the parent instance, it can be a service or any object that implements the interface if your use case allows it.

The complete example is on this stackblitz.

string[] lines = File.ReadAllLines(txtProxyListPath.Text);
List<string> list_lines = new List<string>(lines);
Parallel.ForEach(list_lines, line =>
{
    //Your stuff
});

This is very simple.

1. Unit testing: This is the testing actually done by developers that have coding knowledge. This testing is done at the coding phase and it is a part of white box testing. When a software comes for development, it is developed into the piece of code or slices of code known as a unit. And individual testing of these units called unit testing done by developers to find out some kind of human mistakes like missing of statement coverage etc..

2. Functional testing: This testing is done at testing (QA) phase and it is a part of black box testing. The actual execution of the previously written test cases. This testing is actually done by testers, they find the actual result of any functionality in the site and compare this result to the expected result. If they found any disparity then this is a bug.

3. Acceptance testing: know as UAT. And this actually done by the tester as well as developers, management team, author, writers, and all who are involved in this project. To ensure the project is finally ready to be delivered with bugs free.

4. Integration testing: The units of code (explained in point 1) are integrated with each other to complete the project. These units of codes may be written in different coding technology or may these are of different version so this testing is done by developers to ensure that all units of the code are compatible with other and there is no any issue of integration.

An absolute URI specifies a scheme; a URI that is not absolute is said to be relative.

http://docs.oracle.com/javase/8/docs/api/java/net/URI.html

So, perhaps your URLEncoder isn't working as you're expecting (the https bit)?

    URLEncoder.encode(uri) 

let content = "<center><h1>404 Not Found</h1></center>"
let result = $("<div/>").html(content).text()

content: <center><h1>404 Not Found</h1></center>,
result: "404 Not Found"

select t.name as TriggerName,m.definition,is_disabled 
from sys.all_sql_modules m 
inner join  
sys.triggers t
on m.object_id = t.object_id 
inner join sys.objects o
on o.object_id = t.parent_id
Where o.name = 'YourTableName'

This will give you all triggers on a Specified Table

So many wrong answers!

To specify the value that a form field should revert to upon resetting the form, use the following properties:

• Checkbox or radio button: defaultChecked
• Any other <input> control: defaultValue
• Option in a drop down list: defaultSelected

So, to specify the currently selected option as the default:

var country = document.getElementById("country");
country.options[country.selectedIndex].defaultSelected = true;

It may be a good idea to set the defaultSelected value for every option, in case one had previously been set:

var country = document.getElementById("country");
for (var i = 0; i < country.options.length; i++) {
    country.options[i].defaultSelected = i == country.selectedIndex;
}

Now, when the form is reset, the selected option will be the one you specified.

Proxy timeouts are well, for proxies, not for FastCGI...

The directives that affect FastCGI timeouts are client_header_timeout, client_body_timeout and send_timeout.

Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout which is affecting the fastcgi process response timeout.

HTH.

Try filter to subset only the rows of P1 and P3

df2 <- filter(df, ID == "P1" | ID == "P3")

Than yo can plot Value1. vs Value2.

Note also that vertical-align:top; is often necessary for correct table cell appearance.

css table-cell, contents have unnecessary top margin

You should also use <label for="checkbox1">Checkbox 1</label> because then people can click on the label text as well as the checkbox itself. Its also easier to style and at least in IE it will be highlighted when you tab through the page's controls.

<%= Html.CheckBox("cbNewColors", true) %><label for="cbNewColors">New colors</label>

This is not just a 'oh I could do it' thing. Its a significant user experience enhancement. Even if not all users know they can click on the label many will.

[update] -- Well, my own foolishness provides the answer to this one. As it turns out, I was deleting the records from myTable before running the select COUNT statement.

How did I do that and not notice? Glad you asked. I've been testing a sql unit testing platform (tsqlunit, if you're interested) and as part of one of the tests I ran a truncate table statement, then the above. After the unit test is over everything is rolled back, and records are back in myTable. That's why I got a record count outside of my tests.

Sorry everyone...thanks for your help.

2019 Update

There are various ways to handle this more elegantly now. Please see some other answers on this thread. Tech moves fast so answers can often become out of date fairly quickly. My answer will still work but it's worth looking at alternatives as well.

2012 Answer

Using your code, the issue is that you haven't waited for a socket to be assigned to the request before attempting to set stuff on the socket object. It's all async so:

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
});

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
});

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

The 'socket' event is fired when the request is assigned a socket object.

See this http://blog.stevenlevithan.com/archives/date-time-format

you can do anything with date.

file : http://stevenlevithan.com/assets/misc/date.format.js

add this to your html code using script tag and to use you can use it as :

var now = new Date();

now.format("m/dd/yy");
// Returns, e.g., 6/09/07

You may also want to use hasOwnProperty in the loop.

for (var prop in obj) {
    if (obj.hasOwnProperty(prop)) {
        switch (prop) {
            // obj[prop] has the value
        }
    }
}

node.js is single-threaded which means your script will block whether you want it or not. Remember that V8 (Google's Javascript engine that node.js uses) compiles Javascript into machine code which means that most basic operations are really fast and looping through an object with 100 keys would probably take a couple of nanoseconds?

However, if you do a lot more inside the loop and you don't want it to block right now, you could do something like this

switch (prop) {
    case 'Timestamp':
        setTimeout(function() { ... }, 5);
        break;
    case 'Start_Value':
        setTimeout(function() { ... }, 10);
        break;
}

If your loop is doing some very CPU intensive work, you will need to spawn a child process to do that work or use web workers.

We can find these by looking at Bootstrap's stylesheet, Bootstrap.css. Each \{number} represents a hexadecimal value, so \2a is equal to 0x2a or *.

Try this

git clone ssh://[email protected]:11111/home/git/repo.git

I found this:

EXECUTE xp_regread
        @rootkey = 'HKEY_LOCAL_MACHINE',
        @key = 'SOFTWARE\Microsoft\Microsoft SQL Server',
        @value_name = 'InstalledInstances'

That will give you list of all instances installed in your server.

The ServerName property of the SERVERPROPERTY function and @@SERVERNAME return similar information. The ServerName property provides the Windows server and instance name that together make up the unique server instance. @@SERVERNAME provides the currently configured local server name.

And Microsoft example for current server is:

SELECT CONVERT(sysname, SERVERPROPERTY('servername'));

This scenario is useful when there are multiple instances of SQL Server installed on a Windows server, and the client must open another connection to the same instance used by the current connection.

Also you can use f-string formatting to write integer to file

For appending use following code, for writing once replace 'a' with 'w'.

for i in s_list:
    with open('path_to_file','a') as file:
        file.write(f'{i}\n')

file.close()

Below is the formula I use. I had a problem using GCD, because I use fairly large numbers to calculate the ratios from, and I found ratios such as "209:1024" to be less useful than simply rounding so it displays either "1:" or ":1". I also prefer not to use macros, if at all possible. Below is the result.

=IF(A1>B1,((ROUND(A1/B1,0))&":"&(B1/B1)),((A1/A1)&":"&(ROUND(B1/A1,0))))

Some of the formula is unnecessary (e.g., "A1/A1"), but I included it to show the logic behind it. Also, you can toggle how much rounding occurs by playing with the setting on each ROUND function.

ran across this page and several like it all talking about the GIT_DISCOVERY_ACROSS_FILESYSTEM not set message. In my case our sys admin had decided that the apache2 directory needed to be on a mounted filesystem in case the disk for the server stopped working and had to get rebuilt. I found this with a simple df command:

-->  UBIk  <--:root@ns1:[/etc]
--PRODUCTION--(16:48:43)--> df -h
Filesystem                           Size  Used Avail Use% Mounted on
<snip>
/dev/mapper/vgraid-lvapache           63G   54M   60G   1% /etc/apache2
<snip>

To fix this I just put the following in the root user's shell (as they are the only ones who need to be looking at etckeeper revisions:

export GIT_DISCOVERY_ACROSS_FILESYSTEM=1

and all was well and good...much joy.

More notes:

Hopefully that will help someone out somewhere... -wc

In ASP.NET there is similar object, you can use Caching Portions in WebFormsUserControls in order to cache objects of a page for a period of time and save server resources. This is also known as fragment caching.
If you include this code to top of your user control, a version of the control stored in the output cache for 150 seconds. You can create your own control that would contain expire header for a specific resource you want.

<%@ OutputCache Duration="150" VaryByParam="None" %>

This article explain it completely: Caching Portions of an ASP.NET Page

For passing a single integer I agree with Reed Copsey's answer. If in the future you are going to pass more complicated constucts I personally like to pass all my variables as an Anonymous Type. It will look something like this:

foreach(int id in myIdsToCheck)
{
    Task.Factory.StartNew( (Object obj) => 
        {
           var data = (dynamic)obj;
           CheckFiles(data.id, theBlockingCollection,
               cancelCheckFile.Token, 
               TaskCreationOptions.LongRunning, 
               TaskScheduler.Default);
        }, new { id = id }); // Parameter value
}

You can learn more about it in my blog

1. If Data Consistency is highly important - Use Hashtable or Collections.synchronizedMap(Map).
2. If speed/performance is highly important and Data Updating can be compromised- Use ConcurrentHashMap.

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

A standard LEFT JOIN could resolve the problem and, if the fields on join are indexed,
should also be faster

SELECT *
FROM Table1 as t1 LEFT JOIN Table2 as t2 
ON t1.FirstName = t2.FirstName AND t1.LastName=t2.LastName
WHERE t2.BirthDate Is Null

Safe Methods : Get Resource/No modification in resource
Idempotent : No change in resource status if requested many times
Unsafe Methods : Create or Update Resource/Modification in resource
Non-Idempotent : Change in resource status if requested many times

According to your requirement :

1) For safe and idempotent operation (Fetch Resource) use --------- GET METHOD
2) For unsafe and non-idempotent operation (Insert Resource) use--------- POST METHOD
3) For unsafe and idempotent operation (Update Resource) use--------- PUT METHOD
3) For unsafe and idempotent operation (Delete Resource) use--------- DELETE METHOD

git checkout {branch-name} -- {file-name}

This will use the file from the branch of choice.

I like this because posh-git autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local. And --theirs didn't work for me anyways.

A complete solution for anyone that might need it, I've used this with good results so far

JS:

$(".btn-popover-container").each(function() {
    var btn = $(this).children(".popover-btn");
    var titleContainer = $(this).children(".btn-popover-title");
    var contentContainer = $(this).children(".btn-popover-content");

    var title = $(titleContainer).html();
    var content = $(contentContainer).html();

    $(btn).popover({
        html: true,
        title: title,
        content: content,
        placement: 'right'
    });
});

HTML:

<div class="btn-popover-container">
    <button type="button" class="btn btn-link popover-btn">Button Name</button>
    <div class="btn-popover-title">
        Popover Title
    </div>
    <div class="btn-popover-content">
        <form>
          Or Other content..
        </form>
    </div>
</div>

CSS:

.btn-popover-container {
    display: inline-block;
}


.btn-popover-container .btn-popover-title, .btn-popover-container .btn-popover-content {
    display: none;
}

Like all other had said above, you need to add path. But not sure for what reason if I add C:\xampp\php in path of System Variable won't work but if I add it in path of User Variable work fine.

Although I had added and using other command line tools by adding in system variables work fine

So just in case if someone had same problem as me. Windows 10

To prove jkp's point that 'anything on one line will probably be helishly complex to understand', I created a one-liner. Please do not mod me down because I understand this is not a solution that you should actually use. It is just for demonstrational purposes.

The idea is to add the values in a one by one, as long as the total times you have added that value does is smaller than the total number of times this value is in a minus the number of times it is in b:

[ value for counter,value in enumerate(a) if a.count(value) >= b.count(value) + a[counter:].count(value) ]

The horror! But perhaps someone can improve on it? Is it even bug free?

Edit: Seeing Devin Jeanpierre comment about using a dictionary datastructure, I came up with this oneliner:

sum([ [value]*count for value,count in {value:a.count(value)-b.count(value) for value in set(a)}.items() ], [])

Better, but still unreadable.

None of the solutions out there worked for me. What I eventually discovered was the following combination:

• Client system: Windows XP Pro SP3
• Client system has .NET Framework 2 SP1, 3, 3.5 installed
• Software targeting .NET 2 using classic web services (.asmx)
• Server: IIS6
• Web site "Secure Communications" set to:
  • Require Secure Channel
  • Accept client certificates

Apparently, it was this last option that was causing the issue. I discovered this by trying to open the web service URL directly in Internet Explorer. It just hung indefinitely trying to load the page. Disabling "Accept client certificates" allowed the page to load normally. I am not sure if it was a problem with this specific system (maybe a glitched client certificate?) Since I wasn't using client certificates this option worked for me.

You have to set Connection property of Command object and use parametersized query instead of hardcoded SQL to avoid SQL Injection.

 using(SqlConnection openCon=new SqlConnection("your_connection_String"))
    {
      string saveStaff = "INSERT into tbl_staff (staffName,userID,idDepartment) VALUES (@staffName,@userID,@idDepartment)";

      using(SqlCommand querySaveStaff = new SqlCommand(saveStaff))
       {
         querySaveStaff.Connection=openCon;
         querySaveStaff.Parameters.Add("@staffName",SqlDbType.VarChar,30).Value=name;
         .....
         openCon.Open();

         querySaveStaff.ExecuteNonQuery();
       }
     }

$('#myinput').is(':checkbox')

this is the only work, to solve the issue to detect if checkbox checked or not. It returns true or false, I search it for hours and try everything, now its work to be clear I use EDG as browser and W2UI

Short answer

hibernate.dialect property makes Hibernate to generate the appropriate SQL statements for the chosen database.

Step 1:

Locate phpMyAdmin installation path.

Step 2:

Open phpMyAdmin/config.inc.php in your favourite text editor. Copy config.sample.inc.php to config.inc.php if it's missing.

Step 3:

Search for $cfg['Servers'][$i]['auth_type'] = 'config';

Replace it with $cfg['Servers'][$i]['auth_type'] = 'cookie';

background-image takes an url as a value. Use either

background-image: url ('/image/btn.png');

or

background: url ('/image/btn.png') no-repeat;

which is a shorthand for

background-image: url ('/image/btn.png');
background-repeat: no-repeat;

Also, you might want to look at the button HTML element for fancy submit buttons.

Since Git 2.13.0, it supports a new option to show the path of the root project, which works even when being used from inside a submodule:

git rev-parse --show-superproject-working-tree

Check here for how to add the activedirectory module if not there by default. This can be done on any machine and then it will allow you to access your active directory "domain control" server.

EDIT

To prevent problems with stale links (I have found MSDN blogs to disappear for no reason in the past), in essence for Windows 7 you need to download and install Remote Server Administration Tools (KB958830). After installing do the following steps:

• Open Control Panel -> Programs and Features -> Turn On/Off Windows Features
• Find "Remote Server Administration Tools" and expand it
• Find "Role Administration Tools" and expand it
• Find "AD DS And AD LDS Tools" and expand it
• Check the box next to "Active Directory Module For Windows PowerShell".
• Click OK and allow Windows to install the feature

Windows server editions should already be OK but if not you need to download and install the Active Directory Management Gateway Service. If any of these links should stop working, you should still be able search for the KB article or download names and find them.

Widget _gridView() {
    return GridView.count(
      crossAxisCount: 4,
      padding: EdgeInsets.all(4.0),
      childAspectRatio: 8.0 / 9.0,
      children: itemList
          .map(
            (Item) => ItemList(item: Item),
          )
          .toList(),
    );
  }

Below screenshot contains crossAxisCount: 2

I got similar case but in contrary is to find the used key based on index of a given object's. I could find solution in underscore using Object.values to returns object in to an array to get the occurred index.

var tv = {id1:1,id2:2};_x000D_
var voteIndex = 1;_x000D_
console.log(_.findKey(tv, function(item) {_x000D_
  return _.indexOf(Object.values(tv), item) == voteIndex;_x000D_
}));

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.9.1/underscore-min.js"></script>

If you want to overwrite the element with key 0

function[0] = 42;

Otherwise:

function.insert(std::make_pair(0, 42));

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

To whoever this may help, this saved my life...

IIS 7 was difficult for figuring out why i was getting the 401 - Unauthorized: Access is denied due to invalid credentials... until i did this...

1. Open IIS and select the website that is causing the 401
2. Open the "Authentication" property under the "IIS" header
3. Click the "Windows Authentication" item and click "Providers"
4. For me the issue was that Negotiate was above NTLM. I assume that there was some kind of handshake going on behind the scenes, but i was never really authenticated. I moved the NTLM to the top most spot, and BAM that fixed it.

Here is the link where this was found.

for an android screen you can use this property elevation.

for example :

 HeaderView:{
    backgroundColor:'#F8F8F8',
    justifyContent:'center',
    alignItems:'center',
    height:60,
    paddingTop:15,

    //Its for IOS
    shadowColor: '#000',
    shadowOffset: { width: 0, height: 2 },
    shadowOpacity: 0.2,

    // its for android 
    elevation: 5,
    position:'relative',

},

I use Blue Ocean plugin and did not like each environment entry getting its own block. I want one block with all the lines.

Prints poorly:

sh 'echo `env`'

Prints poorly:

sh 'env > env.txt'
for (String i : readFile('env.txt').split("\r?\n")) {
    println i
}

Prints well:

sh 'env > env.txt'
sh 'cat env.txt'

Prints well: (as mentioned by @mjfroehlich)

echo sh(script: 'env', returnStdout: true)

vim also can convert files from UNIX to DOS format. For example:

vim hello.txt <<EOF
:set fileformat=dos
:wq
EOF

If you install the composer as global on Ubuntu, you just need to find the composer location.

Use command

type composer

or

where composer

For Mac users, use command:

which composer

and then just remove the folder using rm command.

I needed a common event handler in which I can show from which button it is called without using switch case... and done like this..

  Private Sub btn_done_clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)

    MsgBox.Show("you have clicked button " & CType(CType(sender,  _
    System.Windows.Forms.Button).Tag, String))

  End Sub

Mockito is not a DI framework and even DI frameworks encourage constructor injections over field injections.
So you just declare a constructor to set dependencies of the class under test :

@Mock
private SomeService serviceMock;

private Demo demo;

/* ... */
@BeforeEach
public void beforeEach(){
   demo = new Demo(serviceMock);
}

Using Mockito spy for the general case is a terrible advise. It makes the test class brittle, not straight and error prone : What is really mocked ? What is really tested ?
@InjectMocks and @Spy also hurts the overall design since it encourages bloated classes and mixed responsibilities in the classes.
Please read the spy() javadoc before using that blindly (emphasis is not mine) :

Creates a spy of the real object. The spy calls real methods unless they are stubbed. Real spies should be used carefully and occasionally, for example when dealing with legacy code.

As usual you are going to read the partial mock warning: Object oriented programming tackles complexity by dividing the complexity into separate, specific, SRPy objects. How does partial mock fit into this paradigm? Well, it just doesn't... Partial mock usually means that the complexity has been moved to a different method on the same object. In most cases, this is not the way you want to design your application.

However, there are rare cases when partial mocks come handy: dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.) However, I wouldn't use partial mocks for new, test-driven & well-designed code.

To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.

JPA 1.0

With JPA 1.0, you'd have to use EntityManager#getDelegate(). But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:

org.hibernate.Session session = (Session) manager.getDelegate();

But with GlassFish, you'd have to do:

org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); 

I agree, that's horrible, and the spec is to blame here (not clear enough).

JPA 2.0

With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>) method that is to be preferred over EntityManager#getDelegate() for new applications.

So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:

Session session = entityManager.unwrap(Session.class);

The inbuilt function abs() would do the trick.

positivenum = abs(negativenum)

I've been verifying calls in the same manner - I believe it is the right way to do it.

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => mo.Id == 5 && mo.description == "test")
  ), Times.Once());

If your lambda expression becomes unwieldy, you could create a function that takes MyObject as input and outputs true/false...

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => MyObjectFunc(mo))
  ), Times.Once());

private bool MyObjectFunc(MyObject myObject)
{
  return myObject.Id == 5 && myObject.description == "test";
}

Also, be aware of a bug with Mock where the error message states that the method was called multiple times when it wasn't called at all. They might have fixed it by now - but if you see that message you might consider verifying that the method was actually called.

EDIT: Here is an example of calling verify multiple times for those scenarios where you want to verify that you call a function for each object in a list (for example).

foreach (var item in myList)
  mockRepository.Verify(mr => mr.Update(
    It.Is<MyObject>(i => i.Id == item.Id && i.LastUpdated == item.LastUpdated),
    Times.Once());

Same approach for setup...

foreach (var item in myList) {
  var stuff = ... // some result specific to the item
  this.mockRepository
    .Setup(mr => mr.GetStuff(item.itemId))
    .Returns(stuff);
}

So each time GetStuff is called for that itemId, it will return stuff specific to that item. Alternatively, you could use a function that takes itemId as input and returns stuff.

this.mockRepository
    .Setup(mr => mr.GetStuff(It.IsAny<int>()))
    .Returns((int id) => SomeFunctionThatReturnsStuff(id));

One other method I saw on a blog some time back (Phil Haack perhaps?) had setup returning from some kind of dequeue object - each time the function was called it would pull an item from a queue.

to convert the current datetime to file name to save files you can use

DateTime.Now.ToFileTime();

this should resolve your objective

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

Here is the simple and single line of code

For this use the SQL Inbuild RAND() function.

Here is the formula to generate random number between two number (RETURN INT Range)

Here a is your First Number (Min) and b is the Second Number (Max) in Range

SELECT FLOOR(RAND()*(b-a)+a)

Note: You can use CAST or CONVERT function as well to get INT range number.

( CAST(RAND()*(25-10)+10 AS INT) )

Example:

SELECT FLOOR(RAND()*(25-10)+10);

Here is the formula to generate random number between two number (RETURN DECIMAL Range)

SELECT RAND()*(b-a)+a;

Example:

SELECT RAND()*(25-10)+10;

More details check this: https://www.techonthenet.com/sql_server/functions/rand.php

Let's say that your time value is in cell A1 then in A2 you can put:

=A1*1000*60*60*24

or simply:

=A1*86400000

What I am doing is taking the decimal value of the time and multiply it by 1000 (milliseconds) and 60 (seconds) and 60 (minutes) and 24 (hours).

You will then need to format cell A2 as General for it to be in milliseconds format.

If your time is a text value then use:

=TIMEVALUE(A1)*86400000

UPDATE

Per @dandfra's comment this solution may not work in the Italian version of Excel.

In MySQL you can use,

(SELECT CITY, 
        LENGTH(CITY) AS CHR_LEN 
 FROM   STATION 
 ORDER  BY CHR_LEN ASC, 
           CITY 
 LIMIT  1) 
UNION 
(SELECT CITY, 
        LENGTH(CITY) AS CHR_LEN 
 FROM   STATION 
 ORDER  BY CHR_LEN DESC, 
           CITY 
 LIMIT  1) 

To support IE11 with auto-placement, I converted grid to table layout every time I used the grid layout in 1 dimension only. I also used margin instead of grid-gap.

The result is the same, see how you can do it here https://jsfiddle.net/hp95z6v1/3/

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

No, CSV doesn't specify any way of tagging comments - they will just be loaded by programs like Excel as additional cells containing text.

The closest you can manage (with CSV being imported into a specific application such as Excel) is to define a special way of tagging comments that Excel will ignore. For Excel, you can "hide" the comment (to a limited degree) by embedding it into a formula. For example, try importing the following csv file into Excel:

=N("This is a comment and will appear as a simple zero value in excel")
John, Doe, 24

You still end up with a cell in the spreadsheet that displays the number 0, but the comment is hidden.

Alternatively, you can hide the text by simply padding it out with spaces so that it isn't displayed in the visible part of cell:

                              This is a sort-of hidden comment!,
John, Doe, 24

Note that you need to follow the comment text with a comma so that Excel fills the following cell and thus hides any part of the text that doesn't fit in the cell.

Nasty hacks, which will only work with Excel, but they may suffice to make your output look a little bit tidier after importing.

Use the built-in MSDB.DBO.AGENT_DATETIME(20150119,0)

https://blog.sqlauthority.com/2015/03/13/sql-server-interesting-function-agent_datetime/

The reason you are getting rejected is that your tag lost sync with the remote version. This is the same behaviour with branches.

sync with the tag from the remote via git pull --rebase <repo_url> +refs/tags/<TAG> and after you sync, you need to manage conflicts. If you have a diftool installed (ex. meld) git mergetool meld use it to sync remote and keep your changes.

The reason you're pulling with --rebase flag is that you want to put your work on top of the remote one so you could avoid other conflicts.

Also, what I don't understand is why would you delete the dev tag and re-create it??? Tags are used for specifying software versions or milestones. Example of git tags v0.1dev, v0.0.1alpha, v2.3-cr(cr - candidate release) and so on..

Another way you can solve this is issue a git reflog and go to the moment you pushed the dev tag on remote. Copy the commit id and git reset --mixed <commmit_id_from_reflog> this way you know your tag was in sync with the remote at the moment you pushed it and no conflicts will arise.

To change the text colour of UILable at runtime use NSAttributedText and do not set UILable.textColor.

let font = UIFont(name: "SFProText-Semibold", size: 16)!
if let messageToDisplay = currentUser?.lastMessage {

    let attributedString = NSAttributedString(string: messageToDisplay, attributes: [NSAttributedString.Key.font: font, NSAttributedString.Key.foregroundColor: UIColor(named: "charcoal")!])
    lastMessageLabel.attributedText = attributedString
} else {
    let attributedString = NSAttributedString(string: "Start a conversation", attributes: [NSAttributedString.Key.font: font, NSAttributedString.Key.foregroundColor: UIColor(named: "ocean")!])
    lastMessageLabel.attributedText = attributedString
}

Note charcoal and ocean are colours defined in Assets.xcassets. Resultant Label Images:

Above code worked well for me in Xcode 10.2.1 and Swift 5.

Just Add scrolling="no" and seamless="seamless" attributes to iframe tag. like this:-

 1. XHTML => scrolling="no"
 2. HTML5 => seamless="seamless"

UPDATE:

seamless attribute has been removed in all major browsers

I tried the above methods for pushing an object into an array of objects in useState but had the following error when using TypeScript:

Type 'TxBacklog[] | undefined' must have a 'Symbol.iterator' method that returns an iterator.ts(2488)

The setup for the tsconfig.json was apparently right:

{
   "compilerOptions": {
   "target": "es6",
   "lib": [
      "dom",
      "dom.iterable",
      "esnext",
      "es6",
],

This workaround solved the problem (my sample code):

Interface:

   interface TxBacklog {
      status: string,
      txHash: string,
   }

State variable:

    const [txBacklog, setTxBacklog] = React.useState<TxBacklog[]>();

Push new object into array:

    // Define new object to be added
    const newTx = {
       txHash: '0x368eb7269eb88ba86..',
       status: 'pending'
    };
    // Push new object into array
    (txBacklog) 
       ? setTxBacklog(prevState => [ ...prevState!, newTx ])
       : setTxBacklog([newTx]);

I know that this thread is quite old, but I had this problem and I came up with a cool solution which can be very useful to many because it corrects/extended the Volley library on many aspects.

I spotted some not supported-out-of-box Volley features:

• This JSONObjectRequest is not perfect: you have to expect a JSON at the end (see the Response.Listener<JSONObject>).
• What about Empty Responses (just with a 200 status)?
• What do I do if I want directly my POJO from the ResponseListener?

I more or less compiled a lot of solutions in a big generic class in order to have a solution for all the problem I quoted.

It could seem a bit overkill but it's pretty cool to have all these constructors because you have all the cases:

(The main constructor wasn't meant to be used directly although it's, of course, possible).

1. Request with response parsed to POJO / Headers manually set / POJO to Send
2. Request with response parsed to POJO / POJO to Send
3. Request with response parsed to POJO / String to Send
4. Request with response parsed to POJO (GET)
5. Request with response parsed to POJO (GET) / Headers manually set
6. Request with no response (200 - Empty Body) / Headers manually set / POJO to Send
7. Request with no response (200 - Empty Body) / POJO to Send
8. Request with no response (200 - Empty Body) / String to Send

Of course, in order that it works, you have to have Google's GSON Lib; just add:

compile 'com.google.code.gson:gson:x.y.z'

to your dependencies (current version is 2.3.1).

Although I use Vim, some of my co-workers use SlickEdit which looks pretty good. I'm not certain about integrated debugging because we wouldn't be able to do that on our particular project anyway.

SlickEdit does have good support for navigating large code bases, with cross referencing and tag jumping. Of course it has the basic stuff like syntax highlighting and code completion too.

The event IDs to look for in pre-Vista Windows are 528, 538, and 680. 528 usually stands for successful unlock of workstation.

The codes for newer Windows versions differ, see below answers for more infos.

For Swift 3.0+ see the other answers. This is now a legacy answer for Swift 2.x

As answered above, since you are interested in removing the first character the .stringByTrimmingCharactersInSet() instance method will work nicely:

myString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())

You can also make your own character sets to trim the boundaries of your strings by, ex:

myString.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))

There is also a built in instance method to deal with removing or replacing substrings called stringByReplacingOccurrencesOfString(target: String, replacement: String). It can remove spaces or any other patterns that occur anywhere in your string

You can specify options and ranges, but don't need to:

myString.stringByReplacingOccurrencesOfString(" ", withString: "")

This is an easy way to remove or replace any repeating pattern of characters in your string, and can be chained, although each time through it has to take another pass through your entire string, decreasing efficiency. So you can do this:

 myString.stringByReplacingOccurrencesOfString(" ", withString: "").stringByReplacingOccurrencesOfString(",", withString: "")

...but it will take twice as long.

.stringByReplacingOccurrencesOfString() documentation from Apple site

Chaining these String instance methods can sometimes be very convenient for one off conversions, for example if you want to convert a short NSData blob to a hex string without spaces in one line, you can do this with Swift's built in String interpolation and some trimming and replacing:

("\(myNSDataBlob)").stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>")).stringByReplacingOccurrencesOfString(" ", withString: "")

The answer will not work when using the overload to indicate the template @Html.DisplayFor(x => x.Foos, "YourTemplateName) .

Seems to be designed that way, see this case. Also the exception the framework gives (about the type not been as expected) is quite misleading and fooled me on the first try (thanks @CodeCaster)

In this case you have to use @foreach

@foreach (var item in Model.Foos)
{
    @Html.DisplayFor(x => item, "FooTemplate")
}

In case you want to sort dates with descending order the minus sign doesn't work with Dates.

out <- DF[rev(order(as.Date(DF$end))),]

However you can have the same effect with a general purpose function: rev(). Therefore, you mix rev and order like:

#init data
DF <- data.frame(ID=c('ID3', 'ID2','ID1'), end=c('4/1/09 12:00', '6/1/10 14:20', '1/1/11 11:10')
#change order
out <- DF[rev(order(as.Date(DF$end))),]

Hope it helped.

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

Changing the property to an empty string appears to do the job:

$.css("background-color", "");

I think using the STL method 'remove_if' from could help to prevent some weird issue when trying to attempt to delete the object that is wrapped by the iterator.

This solution may be less efficient.

Let's say we have some kind of container, like vector or a list called m_bullets:

Bullet::Ptr is a shared_pr<Bullet>

'it' is the iterator that 'remove_if' returns, the third argument is a lambda function that is executed on every element of the container. Because the container contains Bullet::Ptr, the lambda function needs to get that type(or a reference to that type) passed as an argument.

 auto it = std::remove_if(m_bullets.begin(), m_bullets.end(), [](Bullet::Ptr bullet){
    // dead bullets need to be removed from the container
    if (!bullet->isAlive()) {
        // lambda function returns true, thus this element is 'removed'
        return true;
    }
    else{
        // in the other case, that the bullet is still alive and we can do
        // stuff with it, like rendering and what not.
        bullet->render(); // while checking, we do render work at the same time
        // then we could either do another check or directly say that we don't
        // want the bullet to be removed.
        return false;
    }
});
// The interesting part is, that all of those objects were not really
// completely removed, as the space of the deleted objects does still 
// exist and needs to be removed if you do not want to manually fill it later 
// on with any other objects.
// erase dead bullets
m_bullets.erase(it, m_bullets.end());

'remove_if' removes the container where the lambda function returned true and shifts that content to the beginning of the container. The 'it' points to an undefined object that can be considered garbage. Objects from 'it' to m_bullets.end() can be erased, as they occupy memory, but contain garbage, thus the 'erase' method is called on that range.

To clear all rows that have data I use two variables like this. I like this because you can adjust it to a certain range of columns if you need to. Dim CRow As Integer Dim LastRow As Integer

CRow = 1
LastRow = Cells(Rows.Count, 3).End(xlUp).Row

Do Until CRow = LastRow + 1
    Cells(CRow, 1).Value = Empty
    Cells(CRow, 2).Value = Empty
    Cells(CRow, 3).Value = Empty
    Cells(CRow, 4).Value = Empty
    CRow = CRow + 1
Loop

I had the file excluded from the project so i was not able to debug and have intellisense on that file. Including the file back into the project solved my problem! :)

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

Let me please update the acdcjunior's answer about using HttpInterceptor with the latest RxJs features(v.6).

import { Injectable } from '@angular/core';
import {
  HttpInterceptor,
  HttpRequest,
  HttpErrorResponse,
  HttpHandler,
  HttpEvent,
  HttpResponse
} from '@angular/common/http';

import { Observable, EMPTY, throwError, of } from 'rxjs';
import { catchError } from 'rxjs/operators';

@Injectable()
export class HttpErrorInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

    return next.handle(request).pipe(
      catchError((error: HttpErrorResponse) => {
        if (error.error instanceof Error) {
          // A client-side or network error occurred. Handle it accordingly.
          console.error('An error occurred:', error.error.message);
        } else {
          // The backend returned an unsuccessful response code.
          // The response body may contain clues as to what went wrong,
          console.error(`Backend returned code ${error.status}, body was: ${error.error}`);
        }

        // If you want to return a new response:
        //return of(new HttpResponse({body: [{name: "Default value..."}]}));

        // If you want to return the error on the upper level:
        //return throwError(error);

        // or just return nothing:
        return EMPTY;
      })
    );
  }
}

What's wrong with self.left = None?

you can try this function , very basic

public String getWithoutExtension(String fileFullPath){
    return fileFullPath.substring(0, fileFullPath.lastIndexOf('.'));
}

The exception can also occur because of the class path not being defined.

After hours of research and literally going through hundreds of pages, the problem was that the class path of the library was not defined.

Set the class path as follows in your windows machine

set classpath=path\to\your\jdbc\jar\file;.

There is no: nono and no: yesyes. The truth is in the middle And no reasons to be scared because of the next version of Angular.

From a logical point of view, if You have a Component and You want to inform other components that something happens, an event should be fired and this can be done in whatever way You (developer) think it should be done. I don't see the reason why to not use it and i don't see the reason why to use it at all costs. Also the EventEmitter name suggests to me an event happening. I usually use it for important events happening in the Component. I create the Service but create the Service file inside the Component Folder. So my Service file becomes a sort of Event Manager or an Event Interface, so I can figure out at glance to which event I can subscribe on the current component.

I know..Maybe I'm a bit an old fashioned developer. But this is not a part of Event Driven development pattern, this is part of the software architecture decisions of Your particular project.

Some other guys may think that use Observables directly is cool. In that case go ahead with Observables directly. You're not a serial killer doing this. Unless you're a psychopath developer, So far the Program works, do it.

Provide the full path of the file openfile.exe and remember not to put forward slash / in the path such as c:/users/username/etc.... instead of that use c:\\Users\\username\etc (for windows)

May be this will help you.

Windows 7 Professional I Modified @mongoose_za's answer to make it easier to change the python version:

1. [Right Click]Computer > Properties >Advanced System Settings > Environment Variables
2. Click [New] under "System Variable"
3. Variable Name: PY_HOME, Variable Value:C:\path\to\python\version
4. Click [OK]
5. Locate the "Path" System variable and click [Edit]

6. Add the following to the existing variable:

   %PY_HOME%;%PY_HOME%\Lib;%PY_HOME%\DLLs;%PY_HOME%\Lib\lib-tk;

7. Click [OK] to close all of the windows.

As a final sanity check open a command prompt and enter python. You should see

>python [whatever version you are using]

If you need to switch between versions, you only need to modify the PY_HOME variable to point to the proper directory. This is bit easier to manage if you need multiple python versions installed.

Edit: The plugin now works with trailing whitespace characters. Thanks for pointing it out @JavaSpyder

Since most other answers didn't match what I needed(or simply didn't work at all) I modified Adrian B's answer into a proper jQuery plugin that results in pixel perfect scaling of input without requiring you to change your css or html.

Example:https://jsfiddle.net/587aapc2/

Usage:$("input").autoresize({padding: 20, minWidth: 20, maxWidth: 300});

Plugin:

//JQuery plugin:_x000D_
$.fn.textWidth = function(_text, _font){//get width of text with font.  usage: $("div").textWidth();_x000D_
        var fakeEl = $('<span>').hide().appendTo(document.body).text(_text || this.val() || this.text()).css({font: _font || this.css('font'), whiteSpace: "pre"}),_x000D_
            width = fakeEl.width();_x000D_
        fakeEl.remove();_x000D_

I had this problem with storyboard and swift class for ui view controller. Solved it by using the @objc directive:

@objc(MyViewController) class MyViewController

This problem can also occur when you have conflicting tags. If your local version and remote version use same tag name for different commits, you can end up here.

You can solve it my deleting the local tag:

$ git tag --delete foo_tag

use zzz instead of TZD

Example:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

Compiling the original example in Eclipse at compliance 1.8 and with annotation based null analysis enabled, we get this warning:

    directPathToA(y);
                  ^
Null type safety (type annotations): The expression of type 'Integer' needs unchecked conversion to conform to '@NonNull Integer'

This warning is worded in analogy to those warnings you get when mixing generified code with legacy code using raw types ("unchecked conversion"). We have the exact same situation here: method indirectPathToA() has a "legacy" signature in that it doesn't specify any null contract. Tools can easily report this, so they will chase you down all alleys where null annotations need to be propagated but aren't yet.

And when using a clever @NonNullByDefault we don't even have to say this every time.

In other words: whether or not null annotations "propagate very far" may depend on the tool you use, and on how rigorously you attend to all the warnings issued by the tool. With TYPE_USE null annotations you finally have the option to let the tool warn you about every possible NPE in your program, because nullness has become an intrisic property of the type system.

I am just building on Abdennour TOUMI's answer. here are the reasons why:

1.) I agree with Brad, I do not think it is a good idea to extend object that we did not create.

2.) array.length is exactly reliable in javascript, I prefer Array.reduce beacuse a=[1,3];a[1000]=5; , now a.length would return 1001.

function getAverage(arry){
    // check if array
    if(!(Object.prototype.toString.call(arry) === '[object Array]')){
        return 0;
    }
    var sum = 0, count = 0; 
    sum = arry.reduce(function(previousValue, currentValue, index, array) {
        if(isFinite(currentValue)){
            count++;
            return previousValue+ parseFloat(currentValue);
        }
        return previousValue;
    }, sum);
    return count ? sum / count : 0; 
};

First, {"value": .value} can be abbreviated to just {value}.

Second, the --argfile option (available in jq 1.4 and jq 1.5) may be of interest as it avoids having to use the --slurp option.

Putting these together, the two objects in the two files can be combined in the specified way as follows:

$ jq -n --argfile o1 file1 --argfile o2 file2 '$o1 * $o2 | {value}'

The '-n' flag tells jq not to read from stdin, since inputs are coming from the --argfile options here.

Note on --argfile

The jq manual deprecates --argfile because its semantics are non-trivial: if the specified input file contains exactly one JSON entity, then that entity is read as is; otherwise, the items in the stream are wrapped in an array.

If you are uncomfortable using --argfile, there are several alternatives you may wish to consider. In doing so, be assured that using --slurpfile does not incur the inefficiencies of the -s command-line option when the latter is used with multiple files.

I had this problem with Blend for Visual Studio 2015. The Toolbox would just not appear anymore. This turns out to be because Blend is not Visual Studio!

(You can edit your code in Blend and build and run it... It certainly seems like Visual Studio, but it isn't. I'm not sure what the purpose of Blend is...)

You can tell you are in Blend if the task bar icon has big "B" in it. To switch from Blend to Visual Studio, go to View-> Edit in Visual Studio.... It will open up another application that looks just like Blend, except the Solution Explorer is on the right instead of the left, and now you have a toolbox...

Like at least 1 other contributor here, I also have never liked having to add a extra "helper" column, which can create some hassles in various situations. I finally found a solution. There are a couple different formulas that you can use depending on needs and what is in the column, whether there are blank values, etc. For most of my needs, I have landed on using the following simple formula for the Conditional Formatting (CF) formula:

=MOD(Fixed(SUMPRODUCT(1/COUNTIF(CurrentRange,CurrentRange))),2)=0

I create a Named Range called "CurrentRange" using the following formula where [Sheet] is the sheet on which your data results, [DC] is the column with the values on which you want to band your data and [FR] is the first row that the data is in:

=[Sheet]!$[DC]$[FR]:INDIRECT("$[DC]$" & ROW())

The sheet reference and column reference will be based on the column that has the values you are evaluating. NOTE: You have to use a named range in the formula because will throw an error if you try to use range references directly in the CF rule formula.

Basically, the formula works by evaluating for each row the count of all of the unique values for that row and above to the top of your range. That value for each row essentially provides an ascending Unique ID for each new unique value. Then it uses that value in the place of the Row() function within the standard CF MOD function formula for simple alternating row colors (i.e. =Mod(Row(),2)=0).

See the following example that breaks down the formula to show the resulting components in columns to show what it is doing behind the scenes.

In this example, the CurrentRange named range is defined as:

=Sheet1$A$2:INDIRECT("$A$" & ROW())

The Unique ID column contains the following portion of the CF formula:

=Fixed(SUMPRODUCT(1/COUNTIF(CurrentRange,CurrentRange)))

You can see that, as of row 3, the count of unique values from that row and above in the "Color" column is 2 and it remains 2 in each subsequent row until row 6 when the formula finally encounters a 3rd unique value.

The Band column uses the remainder of the formula referring to the result in column B =MOD(B2,2) to show how it gets you to the 1s and 0s that can then be used for CF.

In the end, the point is, you don't need the extra columns. The entire formula can be used in the CF rule + a named range. For me, that means I can stick the basic formula in a template that I use to drop data in and not have to worry about messing with an extra column once the data is dropped in. It just works by default. Additionally, if you need to account for blanks or other complexities or large sets of data you can use other more complex formulas using frequency and match functions.

Hope this helps someone else avoid the frustration I have had for years!

I had a similar problem, caused by not installing the C++ compiler. In my case I was compiling .cpp files for a Python extension, but the compiler is first invoked as c:\mingw\bin\gcc.exe.

Internally, gcc.exe would notice it was asked to compile a .cpp file. It would try to call g++.exe and fail with the same error message:

gcc.exe: CreateProcess: no such file or directory

Here's a simple solution with lambdas:

root = Tk()
root.attributes("-fullscreen", True)
root.bind("<F11>", lambda event: root.attributes("-fullscreen",
                                    not root.attributes("-fullscreen")))
root.bind("<Escape>", lambda event: root.attributes("-fullscreen", False))
root.mainloop()

This will make the screen exit fullscreen when escape is pressed, and toggle fullscreen when F11 is pressed.

Use the Insert method:

ti.Insert(0, initialItem);
