I think the Key and IV used for encryption using command line and decryption using your program are not same.

Please note that when you use the "-k" (different from "-K"), the input given is considered as a password from which the key is derived. Generally in this case, there is no need for the "-iv" option as both key and password will be derived from the input given with "-k" option.

It is not clear from your question, how you are ensuring that the Key and IV are same between encryption and decryption.

In my suggestion, better use "-K" and "-iv" option to explicitly specify the Key and IV during encryption and use the same for decryption. If you need to use "-k", then use the "-p" option to print the key and iv used for encryption and use the same in your decryption program.

I don't have Python 2.7 installed, but in Python 3.3 calling Popen with stdout set to sys.stdout worked just fine. Not before I had escaped the backslashes in the path, though.

>>> import subprocess
>>> import sys
>>> p = subprocess.Popen(['powershell.exe', 'C:\\Temp\\test.ps1'], stdout=sys.stdout)
>>> Hello World

You may also be missing using namespace std;

Try with this

echo date("G:i", strtotime($time));

or you can try like this also

echo date("H:i", strtotime("04:25 PM"));

Just searched for the docs, and found this:

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

{# returns true #}

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

{{ 'cd' in 'abcde' }}

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[] with an index read from stream. Try vector::at() instead of vector::operator[]. This won't solve your problem, but will show which assignment to the vector causes error.

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

If escaping your single quote with another single quote isn't working for you (like it didn't for one of my recent REPLACE() queries), you can use SET QUOTED_IDENTIFIER OFF before your query, then SET QUOTED_IDENTIFIER ON after.

For example

SET QUOTED_IDENTIFIER OFF;

UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");

SET QUOTED_IDENTIFIER OFF;

if (strstr($_SERVER['REQUEST_URI'],'index.php')){
    header('HTTP/1.0 404 Not Found');
    echo "<h1>404 Not Found</h1>";
    echo "The page that you have requested could not be found.";
    exit();
}

If you look at the last two echo lines, that's where you'll see the content. You can customize it however you want.

Very similar to Holger's answer. If you need to grab the URL can do something like:

Uri uri = Context.Request.Url;         
var scheme = uri.Scheme // returns http, https
var scheme2 = uri.Scheme + Uri.SchemeDelimiter; // returns http://, https://
var host = uri.Host; // return www.mywebsite.com
var port = uri.Port; // returns port number

The Uri class provides a whole range of methods, many which I have not listed.

In my instance, I needed to grab LocalHost along with the Port Number, so this is what I did:

var Uri uri = Context.Request.Url;
var host = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port; 

Which successfully grabbed: http://localhost:12345

You can use a javascript image processing framework for client-side image processing before uploading the image to the server.

Below I used MarvinJ to create a runnable code based on the example in the following page: "Processing images in client-side before uploading it to a server"

Basically I use the method Marvin.scale(...) to resize the image. Then, I upload the image as a blob (using the method image.toBlob()). The server answers back providing a URL of the received image.

There are a lot of answers here that use a set(..) (which is fast given the elements are hashable), or a list (which has the downside that it results in an O(n²) algorithm.

The function I propose is a hybrid one: we use a set(..) for items that are hashable, and a list(..) for the ones that are not. Furthermore it is implemented as a generator such that we can for instance limit the number of items, or do some additional filtering.

Finally we also can use a key argument to specify in what way the elements should be unique. For instance we can use this if we want to filter a list of strings such that every string in the output has a different length.

def uniq(iterable, key=lambda x: x):
    seens = set()
    seenl = []
    for item in iterable:
        k = key(item)
        try:
            seen = k in seens
        except TypeError:
            seen = k in seenl
        if not seen:
            yield item
            try:
                seens.add(k)
            except TypeError:
                seenl.append(k)

We can now for instance use this like:

>>> list(uniq(["apple", "pear", "banana", "lemon"], len))
['apple', 'pear', 'banana']
>>> list(uniq(["apple", "pear", "lemon", "banana"], len))
['apple', 'pear', 'banana']
>>> list(uniq(["apple", "pear", {}, "lemon", [], "banana"], len))
['apple', 'pear', {}, 'banana']
>>> list(uniq(["apple", "pear", {}, "lemon", [], "banana"]))
['apple', 'pear', {}, 'lemon', [], 'banana']
>>> list(uniq(["apple", "pear", {}, "lemon", {}, "banana"]))
['apple', 'pear', {}, 'lemon', 'banana']

It is thus a uniqeness filter that can work on any iterable and filter out uniques, regardless whether these are hashable or not.

It makes one assumption: that if one object is hashable, and another one is not, the two objects are never equal. This can strictly speaking happen, although it would be very uncommon.

Xamarin.iOS solution

 public UIImage CreateImageFromColor()
 {
     var imageSize = new CGSize(30, 30);
     var imageSizeRectF = new CGRect(0, 0, 30, 30);
     UIGraphics.BeginImageContextWithOptions(imageSize, false, 0);
     var context = UIGraphics.GetCurrentContext();
     var red = new CGColor(255, 0, 0);
     context.SetFillColor(red);
     context.FillRect(imageSizeRectF);
     var image = UIGraphics.GetImageFromCurrentImageContext();
     UIGraphics.EndImageContext();
     return image;

An easy way to do with HTML+CSS:

TEXT A <b>text b</b>

<h1>text b</h1>

<style>
    h1 { /* the css style */}
    h1:before {content:"text A (p.e.first word) with different style";    
    display:"inline";/* the different css style */}
</style>

I think this is a simple example, how to check if a radio in a group of radios was checked.

if($('input[name=html_elements]:checked').length){
    //a radio button was checked
}else{
    //there was no radio button checked
} 

All methods, tricks, and lines of code setting ComboBox item will not work until the ComboBox has a parent.

They are the same when used for output, e.g. with printf.

However, these are different when used as input specifier e.g. with scanf, where %d scans an integer as a signed decimal number, but %i defaults to decimal but also allows hexadecimal (if preceded by 0x) and octal (if preceded by 0).

So 033 would be 27 with %i but 33 with %d.

Just in case someone is looking for solution in Swift, throw this in your code:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: .UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: .UIKeyboardWillHide, object: nil)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillShow, object: nil)
    NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillHide, object: nil)
}


@objc func keyboardWillShow(notification: Notification) {
    if let userInfo = notification.userInfo {
        if let keyboardSize = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            UIView.animate(withDuration: 0.3) {
                var alteredFrame = self.view.frame
                alteredFrame.origin.y = -keyboardSize.height
                self.view.frame = alteredFrame
            }
        }
    }
}

@objc func keyboardWillHide(notification: Notification) {
    UIView.animate(withDuration: 0.3) {
        var alteredFrame = self.view.frame
        alteredFrame.origin.y = 0.0
        self.view.frame = alteredFrame
    }
}

Java 7 introduced ThreadLocalRandom which is isolated to the current thread.

This is an another rendition of maerics's solution.

final byte[] bytes = new byte[20];
ThreadLocalRandom.current().nextBytes(bytes);

The package name is used for unique identification for your application.
Android uses the package name to determine if the application has been installed or not.
The general naming is:

com.companyname.applicationname

eg:

com.android.Camera

Jython approach

Java is supposed to be platform independent, and to call a native application (like python) isn't very platform independent.

There is a version of Python (Jython) which is written in Java, which allow us to embed Python in our Java programs. As usually, when you are going to use external libraries, one hurdle is to compile and to run it correctly, therefore we go through the process of building and running a simple Java program with Jython.

We start by getting hold of jython jar file:

https://www.jython.org/download.html

I copied jython-2.5.3.jar to the directory where my Java program was going to be. Then I typed in the following program, which do the same as the previous two; take two numbers, sends them to python, which adds them, then python returns it back to our Java program, where the number is outputted to the screen:

import org.python.util.PythonInterpreter; 
import org.python.core.*; 

class test3{
    public static void main(String a[]){

        PythonInterpreter python = new PythonInterpreter();

        int number1 = 10;
        int number2 = 32;
        python.set("number1", new PyInteger(number1));
        python.set("number2", new PyInteger(number2));
        python.exec("number3 = number1+number2");
        PyObject number3 = python.get("number3");
        System.out.println("val : "+number3.toString());
    }
}

I call this file "test3.java", save it, and do the following to compile it:

javac -classpath jython-2.5.3.jar test3.java

The next step is to try to run it, which I do the following way:

java -classpath jython-2.5.3.jar:. test3

Now, this allows us to use Python from Java, in a platform independent manner. It is kind of slow. Still, it's kind of cool, that it is a Python interpreter written in Java.

You can also set these values programatically in the class library, this will avoid unnecessary movement of the config files across the library. The example code for simple BasciHttpBinding is -

BasicHttpBinding basicHttpbinding = new BasicHttpBinding(BasicHttpSecurityMode.None);
basicHttpbinding.Name = "BasicHttpBinding_YourName";
basicHttpbinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
basicHttpbinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;

EndpointAddress endpointAddress = new EndpointAddress("http://<Your machine>/Service1/Service1.svc");
Service1Client proxyClient = new Service1Client(basicHttpbinding,endpointAddress);

An alternative method to finding out the amount of rows in a dataframe which I think is the most readable variant is pandas.Index.size.

Do note that, as I commented on the accepted answer,

Suspected pandas.Index.size would actually be faster than len(df.index) but timeit on my computer tells me otherwise (~150 ns slower per loop).

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

Google's own browser offers such a comprehensive solution to this problem that it warrants it's own class:

openFileChooser implementation in Android 4.0.4

UploadHandler class in Android 4.0.4

You can add join type as well:

Criteria c2 = c.createCriteria("mother", "mother", CriteriaSpecification.LEFT_JOIN);
Criteria c3 = c2.createCriteria("kind", "kind", CriteriaSpecification.LEFT_JOIN);

append([]int{1,2}, []int{3,4}...) will work. Passing arguments to ... parameters.

If f is variadic with a final parameter p of type ...T, then within f the type of p is equivalent to type []T.

If f is invoked with no actual arguments for p, the value passed to p is nil.

Otherwise, the value passed is a new slice of type []T with a new underlying array whose successive elements are the actual arguments, which all must be assignable to T. The length and capacity of the slice is therefore the number of arguments bound to p and may differ for each call site.

Given the function and calls

func Greeting(prefix string, who ...string)
Greeting("nobody")
Greeting("hello:", "Joe", "Anna", "Eileen")

It is very straight forward

HTML

<input type="text" placeholder="some text" />
<input type="button" value="button" class="button"/>
<button class="button">Another button</button>

jQuery

$(document).ready(function(){
  $('.button').css( 'cursor', 'pointer' );

  // for old IE browsers
  $('.button').css( 'cursor', 'hand' ); 
});

Make sure you have a .babelrc file that declares what Babel is supposed to be transpiling. I spent like 30 minutes trying to figure this exact error. After I copied a bunch of files over to a new folder and found out I didn't copy the .babelrc file because it was hidden.

I think I found an algorithm which works quite well, as I often reach scores over 10000, my personal best being around 16000. My solution does not aim at keeping biggest numbers in a corner, but to keep it in the top row.

Please see the code below:

while( !game_over ) {
    move_direction=up;
    if( !move_is_possible(up) ) {
        if( move_is_possible(right) && move_is_possible(left) ){
            if( number_of_empty_cells_after_moves(left,up) > number_of_empty_cells_after_moves(right,up) ) 
                move_direction = left;
            else
                move_direction = right;
        } else if ( move_is_possible(left) ){
            move_direction = left;
        } else if ( move_is_possible(right) ){
            move_direction = right;
        } else {
            move_direction = down;
        }
    }
    do_move(move_direction);
}

You'd most likely need to extract code from a secure web page (https protocol). In the following example, the html file is being saved into c:\temp\filename.html Enjoy!

/**

public class HttpsClientUtil {
    public static void main(String[] args) throws Exception {
        String httpsURL = "https://stackoverflow.com";
        String FILENAME = "c:\\temp\\filename.html";
        BufferedWriter bw = new BufferedWriter(new FileWriter(FILENAME));
        URL myurl = new URL(httpsURL);
        HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection();
        con.setRequestProperty ( "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0" );
        InputStream ins = con.getInputStream();
        InputStreamReader isr = new InputStreamReader(ins, "Windows-1252");
        BufferedReader in = new BufferedReader(isr);
        String inputLine;

        // Write each line into the file
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
            bw.write(inputLine);
        }
        in.close(); 
        bw.close();
    }
}

NetBeans 7 has nice support for HTML5. Previously I was a heavy user of Eclipse, but spend more time with NetBeans to play with HTML5 and Servlet.

In most RDBMSs today, they are synonyms. However for those systems that still have a distinction, a CHAR field is stored as a fixed-width column. If you define it as CHAR(10), then 10 characters are written to the table, where "padding" (typically spaces) is used to fill in any space that the data does not use up. For example, saving "bob" would be saved as ("bob"+7 spaces). A VARCHAR (variable character) column is meant to store data without wasting the extra space that a CHAR column does.

As always, Wikipedia speaks louder.

I spent the better part of a day fiddling with this problem. Turned out the RowBackground Property on the DataGrid - which I had set - was overriding all attempts to change it in . As soon as I deleted it, everything worked. (Same goes for Foreground set in DataGridTextColumn, by the way).

Use array_combine() to fuse the arrays together and iterate over the result.

I got this error while deploying to Virgo. The solution was to add this to my bundle imports:

org.springframework.transaction.config;version="[3.1,3.2)",

I noticed in the Spring jars under META-INF there is a spring.schemas and a spring.handlers section, and the class that they point to (in this case org.springframework.transaction.config.TxNamespaceHandler) must be imported.

If you need a fully qualified domain name and have no HTTP request, on Linux, you could use:

var child_process = require("child_process");

child_process.exec("hostname -f", function(err, stdout, stderr) {
  var hostname = stdout.trim();
});

You can implement the Array.insert method by doing this:

Array.prototype.insert = function ( index, item ) {
    this.splice( index, 0, item );
};

Then you can use it like:

var arr = [ 'A', 'B', 'D', 'E' ];
arr.insert(2, 'C');

// => arr == [ 'A', 'B', 'C', 'D', 'E' ]

There is another option - without using iota. For_each + lambda expression can be used:

vector<int> ivec(10); // the vector of size 10
int i = 0;            // incrementor
for_each(ivec.begin(), ivec.end(), [&](int& item) { ++i; item += i;});

Two important things why it's working:

1. Lambda captures outer scope [&] which means that i will be available inside expression
2. item passed as a reference, therefore, it is mutable inside the vector

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

Add this line in style of v21 if you use two style.

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

This is an interesting question, i just want to give another angle by adding a little more info.You can understand why an exception is thrown if you see how static methods operate. These methods can manipulate either static data, local data or data that is sent to it as a parameter.why? because static method can be accessed by any object, from anywhere. So, there can be security issues posed or there can be leaks of information if it can use instance variables.Hence the compiler has to throw such a case out of consideration.

You might try removing the BufferedWriter and just using the FileWriter directly. On a modern system there's a good chance you're just writing to the drive's cache memory anyway.

It takes me in the range of 4-5 seconds to write 175MB (4 million strings) -- this is on a dual-core 2.4GHz Dell running Windows XP with an 80GB, 7200-RPM Hitachi disk.

Can you isolate how much of the time is record retrieval and how much is file writing?

Installing the "security" package extras for requests solved for me:

How about this

for (int i = 0; i < str.length(); i++) { 
    System.out.println(str.substring(i, i + 1)); 
} 

When I look at this description, I have a feeling, that this xdr integer is just a big-endian "standard" integer, but it's expressed in the most obfuscated way. Two's complement notation is better know as U2, and it's what we are using on today's processors. The byte order indicates that it's a big-endian notation.
So, answering your question, you should inverse elements in your array (0 <--> 3, 1 <-->2), as they are encoded in little-endian. Just to make sure, you should first check BitConverter.IsLittleEndian to see on what machine you are running.

If you don't need ticks and such (e.g. for plotting qualitative illustrations) you could also use this quick workaround:

Make the axis invisible (e.g. with plt.gca().axison = False) and then draw them manually with plt.arrow.

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

& is a logical elementwise operator, while && is a logical short-circuiting operator (which can only operate on scalars).

For example (pardon my syntax).

If..

A = [True True False True]
B = False
A & B = [False False False False]

..or..

B = True
A & B = [True True False True]

For &&, the right operand is only calculated if the left operand is true, and the result is a single boolean value.

x = (b ~= 0) && (a/b > 18.5)

Hope that's clear.

No, you are best off restarting the interpreter

IPython is an excellent replacement for the bundled interpreter and has the %reset command which usually works

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

You are setting it't type as submit. That means that browser should post your <form> data to the server.

In fact a tag has no type attribute according to w3schools.

So remote type attribute and it should work for you.

I typically use

:%s/\r/\r/g

which seems a little odd, but works because of the way that Vim matches linefeeds. I also find it easier to remember :)

For security reasons you must avoid providing password on a command line otherwise anyone running ps command can see your password. Better to use sshpass utility like this:

#!/bin/bash

export SSHPASS="your-password"
sshpass -e ssh -oBatchMode=no sshUser@remoteHost

This is an old question, but the accepted answer has a serious flaw. If the Spring Environment object contains any overriding values (as described in Externalized Configuration), there is no guarantee that the map of property values it produces will match those returned from the Environment object. I found that simply iterating through the PropertySources of the Environment did not, in fact, give any overriding values. Instead it produced the original value, the one that should have been overridden.

Here is a better solution. This uses the EnumerablePropertySources of the Environment to iterate through the known property names, but then reads the actual value out of the real Spring environment. This guarantees that the value is the one actually resolved by Spring, including any overriding values.

Properties props = new Properties();
MutablePropertySources propSrcs = ((AbstractEnvironment) springEnv).getPropertySources();
StreamSupport.stream(propSrcs.spliterator(), false)
        .filter(ps -> ps instanceof EnumerablePropertySource)
        .map(ps -> ((EnumerablePropertySource) ps).getPropertyNames())
        .flatMap(Arrays::<String>stream)
        .forEach(propName -> props.setProperty(propName, springEnv.getProperty(propName)));

To get exactly 10.0001 you need to use the String constructor or valueOf (which constructs a BigDecimal based on the canonical representation of the double):

BigDecimal bd = new BigDecimal("10.0001");
System.out.println(bd.toString()); // prints 10.0001
//or alternatively
BigDecimal bd = BigDecimal.valueOf(10.0001);
System.out.println(bd.toString()); // prints 10.0001

The problem with new BigDecimal(10.0001) is that the argument is a double and it happens that doubles can't represent 10.0001 exactly. So 10.0001 is "transformed" to the closest possible double, which is 10.000099999999999766941982670687139034271240234375 and that's what your BigDecimal shows.

For that reason, it rarely makes sense to use the double constructor.

I just felt like I'll add my $0.2 to those 2 good answers. I had a case when I had to move the last column all the way to the top in a 3-column situation.

[A][B][C]

to

[C]

[A]

[B]

Boostrap's class .col-xx-push-Xdoes nothing else but pushes a column to the right with left: XX%; so all you have to do to push a column right is to add the number of pseudo columns going left.

In this case:

• two columns (col-md-5 and col-md-3) are going left, each with the value of the one that is going right;

• one(col-md-4) is going right by the sum of the first two going left (5+3=8);

<div class="row">
    <div class="col-md-4 col-md-push-8 ">
        C
    </div>
    <div class="col-md-5 col-md-pull-4">
        A
    </div>
    <div class="col-md-3 col-md-pull-4">
        B
    </div>
</div>

One trick I use to tell if X is running is:

telnet 127.0.0.1 6000

If it connects, you have an X server running and its accepting inbound TCP connections (not usually the default these days)....

Here is a good discussion about superclass constructor calling rules. You always want the base class constructor to be called before the derived class constructor in order to form an object properly. Which is why this form is used

  B( int v) : A( v )
  {
  }

If you don't need support for older browsers, just set the iframe width to 100vw;

iframe {
  max-width: 100%; /* Limits width to 100% of container */
  width: 100vw; /* Sets width to 100% of the viewport width while respecting the max-width above */
}

Note : Check support for viewport units https://caniuse.com/#feat=viewport-units

"a" is an integer, when divided with integer it gives you an integer. Then it is assigned to "b" as an integer and becomes a float.

You should do it like this

b = a / 350.0;

bool isValid = c.GetType() == typeof(TForm) ? true : false;

or simpler

bool isValid = c.GetType() == typeof(TForm);

Here you go. Leave the computing to PHP and save your DB some work. This way you can make effective use of an index on the Date column.

<?php
    $date = $_POST['period'];

    $start = strtotime($date);
    $end   = strtotime($date . ' 1 month - 1 second');

    $query = sprintf(
        'SELECT *
           FROM projects
          WHERE Date BETWEEN FROM_UNIXTIME(%u) AND FROM_UNIXTIME(%u)',
        $start,
        $end
    );

Forgot the Unix timestamp conversion.

json_decode() is used to decode a json string to an array/data object. json_encode() creates a json string from an array or data. You are using the wrong function my friend, try json_encode();

A new C++ Excel extension for PHP, though you'll need to build it yourself, and the docs are pretty sparse when it comes to trying to find out what functionality (I can't even find out from the site what formats it supports, or whether it reads or writes or both.... I'm guessing both) it offers is phpexcellib from SIMITGROUP.

All claim to be faster than PHPExcel from codeplex or from github, but (with the exception of COM, PUNO Ilia's wrapper around libXl and spout) they don't offer both reading and writing, or both xls and xlsx; may no longer be supported; and (while I haven't tested Ilia's extension) only COM and PUNO offers the same degree of control over the created workbook.

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

//May be quite some time ago but I just want throw in some line for any one who may still need it

int intValue;
string strValue = "2021";

try
{
    intValue = Convert.ToInt32(strValue);
}
catch
{
    //Default Value if conversion fails OR return specified error
    // Example 
    intValue = 2000;
}

Can you clarify your question? What is "ohHover" in this case and how does it correspond to a delay in hover time?

That said, I think what you probably want is...

var timeout;
element.onmouseover = function(e) {
    timeout = setTimeout(function() {
        // ...
    }, delayTimeMs)
};
element.onmouseout = function(e) {
    if(timeout) {
        clearTimeout(timeout);
    }
};

Or addEventListener/attachEvent or your favorite library's event abstraction method.

Async Arrow function syntax with parameters

const myFunction = async (a, b, c) => {
   // Code here
}

If you want to get the price of all cars you have to iterate through the array list:

public static void processCars(ArrayList<Cars> cars) {
   for (Car c : cars) {
       System.out.println (c.getPrice());
   }
}

I presume you mean via SSMS?

For a SQL Server Instance:

SELECT SERVERPROPERTY('productversion'), 
       SERVERPROPERTY ('productlevel'), 
       SERVERPROPERTY ('edition')

For a SQL Server Installation:

Select @@Version

I am using a class that just uses one of the above methods behind the scenes... I noticed it works on Windows and Linux... I like using it though because it's easier to type clear() instead of system('clear') or os.system('clear')

pip3 install clear-screen

from clear_screen import clear

and then when you want to clear the shell:

clear()

It seems that in RxJS 5.2.0 the .first() operator has a bug,

Because of that bug .take(1) and .first() can behave quite different if you are using them with switchMap:

With take(1) you will get behavior as expected:

var x = Rx.Observable.interval(1000)
   .do( x=> console.log("One"))
   .take(1)
   .switchMap(x => Rx.Observable.interval(1000))
   .do( x=> console.log("Two"))
   .subscribe((x) => {})

// In the console you will see:
// One
// Two
// Two
// Two
// Two
// etc...

But with .first() you will get wrong behavior:

var x = Rx.Observable.interval(1000)
  .do( x=> console.log("One"))
  .first()
  .switchMap(x => Rx.Observable.interval(1000))
  .do( x=> console.log("Two"))
  .subscribe((x) => {})

// In console you will see:
// One
// One
// Two
// One
// Two
// One
// etc...

In addition to @Elltz answer, we can use both fill and image for background:

someNode.setBackground(
            new Background(
                    Collections.singletonList(new BackgroundFill(
                            Color.WHITE, 
                            new CornerRadii(500), 
                            new Insets(10))),
                    Collections.singletonList(new BackgroundImage(
                            new Image("image/logo.png", 100, 100, false, true),
                            BackgroundRepeat.NO_REPEAT,
                            BackgroundRepeat.NO_REPEAT,
                            BackgroundPosition.CENTER,
                            BackgroundSize.DEFAULT))));

Use

setBackground(

(different last argument) to make the image full-window size.

Modern browsers now support the:

width: calc(100% - 100px);

To see the list of supported browser versions checkout: Can I use calc() as CSS unit value?

There is a jQuery fallback: css width: calc(100% -100px); alternative using jquery

You can try U2U Query Builder http://www.u2u.net/res/Tools/CamlQueryBuilder.aspx you can use their API U2U.SharePoint.CAML.Server.dll and U2U.SharePoint.CAML.Client.dll

I didn't use them but I'm sure it will help you achieving your task.

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

The value of the certificate comes mostly from the trust of the internet users in the issuer of the certificate. To that end, Verisign is tough to beat. A certificate says to the client that you are who you say you are, and the issuer has verified that to be true.

You can get a free SSL certificate signed, for example, by StartSSL. This is an improvement on self-signed certificates, because your end-users would stop getting warning pop-ups informing them of a suspicious certificate on your end. However, the browser bar is not going to turn green when communicating with your site over https, so this solution is not ideal.

The cheapest SSL certificate that turns the bar green will cost you a few hundred dollars, and you would need to go through a process of proving the identity of your company to the issuer of the certificate by submitting relevant documents.

It sound like you'll need to use an array, where num[1] = "one", num[2] = "two", and so on. Then you can loop through each like you already are and

num = array(["one","two","three","four","five","six","seven","eight","nine","ten"])
for i in range(10,0,-1):
    print num[i], "Bottles of beer on the wall,"
    print num[i], "bottles of beer."
    print "Take one down and pass it around,"
    print num[i-1], "bottles of beer on the wall."
    print ""

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

Using the quite popular stream-buffers package which you probably already have in your project dependencies, this is pretty straightforward:

// imports
const { WritableStreamBuffer } = require('stream-buffers');
const { promisify } = require('util');
const { createReadStream } = require('fs');
const pipeline = promisify(require('stream').pipeline);

// sample stream
let stream = createReadStream('/etc/hosts');

// pipeline the stream into a buffer, and print the contents when done
let buf = new WritableStreamBuffer();
pipeline(stream, buf).then(() => console.log(buf.getContents().toString()));

It's actually really easy. Highlight the DATE column and make sure that its set as date in Excel. Highlight everything you want to change, Then go to [DATA]>[SORT]>[COLUMN] and set sorting by date. Hope it helps.

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

Those like me who understand character encoding principles, also read Joel's article which is funny as it contains wrong characters anyway and still can't figure out what the heck (spoiler alert, I'm Mac user) then your solution can be as simple as removing your local repo and clone it again.

My code base did not change since the last time it was running OK so it made no sense to have UTF errors given the fact that our build system never complained about it....till I remembered that I accidentally unplugged my computer few days ago with IntelliJ Idea and the whole thing running (Java/Tomcat/Hibernate)

My Mac did a brilliant job as pretending nothing happened and I carried on business as usual but the underlying file system was left corrupted somehow. Wasted the whole day trying to figure this one out. I hope it helps somebody.

If you want to imitate click on the DOM element like this:

<a (click)="showLogin($event)">login</a>

and have something like this on the page:

<li ngbDropdown>
    <a ngbDropdownToggle id="login-menu">
        ...
    </a>
 </li>

your function in component.ts should be like this:

showLogin(event) {
   event.stopPropagation();
   document.getElementById('login-menu').click();
}

Only learning myself, but wrapping in a View may allow you to add styles around the button.

const Stack = StackNavigator({
  Home: {
    screen: HomeView,
    navigationOptions: {
      title: 'Home View'
    }
  },
  CoolView: {
    screen: CoolView,
    navigationOptions: ({navigation}) => ({
      title: 'Cool View',
      headerRight: (<View style={{marginRight: 16}}><Button
        title="Cool"
        onPress={() => alert('cool')}
      /></View>
    )
    })
  }
})

I use a simple approach that handles stale lock files.

Note that some of the above solutions that store the pid, ignore the fact that the pid can wrap around. So - just checking if there is a valid process with the stored pid is not enough, especially for long running scripts.

I use noclobber to make sure only one script can open and write to the lock file at one time. Further, I store enough information to uniquely identify a process in the lockfile. I define the set of data to uniquely identify a process to be pid,ppid,lstart.

When a new script starts up, if it fails to create the lock file, it then verifies that the process that created the lock file is still around. If not, we assume the original process died an ungraceful death, and left a stale lock file. The new script then takes ownership of the lock file, and all is well the world, again.

Should work with multiple shells across multiple platforms. Fast, portable and simple.

            if [ "$CURRENT_UUID_FROM_LOCKFILE" == "$CURRENT_UUID_FROM_PS" ]; then 
                echo "Script already running with following identification: $CURRENT_UUID_FROM_LOCKFILE" >&2
                return 1
            else

                echo "The process $CURRENT_UUID_FROM_LOCKFILE is no longer around. Taking ownership of $LOCKFILE"
                release "FORCE"
                if (echo "$UUID" > "$LOCKFILE") 2>/dev/null; then
                    ACQUIRED="TRUE"
                    return 0

Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.

Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

I ran into a similar problem recently. The solution for me was to re-create the colletion. Let me try to demonstrate:

var $element = $(selector);
$element.append(content);

// This Doesn't work, because $element still contains old structure:
$element.fooBar();    

// This should work: the collection is re-created with the new content:
$(selector).fooBar();

Hope this helps!

I performed that with a 20go sql file from a jetbackup cpanel mysql backup. Be patient to wait vi doing the job for big files

Here is the script in Python.

You cannot click on elements in selenium that are hidden. However, you can execute JavaScript to click on the hidden element for you.

element = driver.find_element_by_id(buttonID)
driver.execute_script("$(arguments[0]).click();", element)

This very annoying error so what I did: Under Windows:

Edit system environment variables - > Edit Variables -> New

then fill

Then restart the console and run the maven build again. No more Maven space/perm size problems.

Proper Swift 3.0 for iOS 10+ solution: Using ImageRenderer and closure syntax:

func imageWith(newSize: CGSize) -> UIImage {
    let renderer = UIGraphicsImageRenderer(size: newSize)
    let image = renderer.image { _ in
        self.draw(in: CGRect.init(origin: CGPoint.zero, size: newSize))
    }

    return image.withRenderingMode(self.renderingMode)
}

And here's the Objective-C version:

@implementation UIImage (ResizeCategory)
- (UIImage *)imageWithSize:(CGSize)newSize
{
    UIGraphicsImageRenderer *renderer = [[UIGraphicsImageRenderer alloc] initWithSize:newSize];
    UIImage *image = [renderer imageWithActions:^(UIGraphicsImageRendererContext*_Nonnull myContext) {
        [self drawInRect:(CGRect) {.origin = CGPointZero, .size = newSize}];
    }];
    return [image imageWithRenderingMode:self.renderingMode];
}
@end

Self Answer (pretty much summary of other's comments and answers):

• In RStudio, Esc works, on windows, Mac, and ubuntu (and I would guess on other linux distributions as well).

• If the process is ran in say ubuntu shell (and this is not R specific), for example using:

  Rscript my_file.R
  

  Ctrl + c kills the process

  Ctrl + z suspends the process

• Within R shell, Ctrl + C kills helps you escape it

PLEASE people... 'Last week' like the OP asked and where I was looking for (but found none of answers satisfying) is THE LAST WEEK.

If today is Tuesday, then LAST WEEK is Monday A WEEK AGO to Sunday A WEEK AGO.

So:

WHERE
    WEEK(yourdate) = WEEK(NOW()) - 1

Or for ISO weeks:

WHERE
    WEEK(yourdate, 3) = WEEK(NOW(), 3) - 1

As an alternative to @Mark Byers' approach, you can use while True:

guess = 50     # this should be outside the loop, I think
while True:    # infinite loop
    n = raw_input("\n\nTrue, False or Correct?: ")
    if n == "Correct":
        break  # stops the loop
    elif n == "True":
        # etc.

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

In my case, the problem was that I assigned a .swift class to the viewController in the storyboard, while the project was Objective C.

Try git fetch --dry-run The manual (git help fetch) says:

Regular expressions to the rescue! These few lines of code handle properly quoted fields with embedded commas, quotes, and newlines based on the RFC 4180 standard.

function parseCsv(data, fieldSep, newLine) {
    fieldSep = fieldSep || ',';
    newLine = newLine || '\n';
    var nSep = '\x1D';
    var qSep = '\x1E';
    var cSep = '\x1F';
    var nSepRe = new RegExp(nSep, 'g');
    var qSepRe = new RegExp(qSep, 'g');
    var cSepRe = new RegExp(cSep, 'g');
    var fieldRe = new RegExp('(?<=(^|[' + fieldSep + '\\n]))"(|[\\s\\S]+?(?<![^"]"))"(?=($|[' + fieldSep + '\\n]))', 'g');
    var grid = [];
    data.replace(/\r/g, '').replace(/\n+$/, '').replace(fieldRe, function(match, p1, p2) {
        return p2.replace(/\n/g, nSep).replace(/""/g, qSep).replace(/,/g, cSep);
    }).split(/\n/).forEach(function(line) {
        var row = line.split(fieldSep).map(function(cell) {
            return cell.replace(nSepRe, newLine).replace(qSepRe, '"').replace(cSepRe, ',');
        });
        grid.push(row);
    });
    return grid;
}

const csv = 'A1,B1,C1\n"A ""2""","B, 2","C\n2"';
const separator = ',';      // field separator, default: ','
const newline = ' <br /> '; // newline representation in case a field contains newlines, default: '\n' 
var grid = parseCsv(csv, separator, newline);
// expected: [ [ 'A1', 'B1', 'C1' ], [ 'A "2"', 'B, 2', 'C <br /> 2' ] ]

Unless stated elsewhere, you don't need a finite state machine. The regular expression handles RFC 4180 properly thanks to positive lookbehind, negative lookbehind, and positive lookahead.

Basically you just need to add lines to ~/.gitconfig

[alias]
    st = status
    ci = commit -v

Or you can use the git config alias command:

$ git config --global alias.st status 

On unix, use single quotes if the alias has a space:

$ git config --global alias.ci 'commit -v'

On windows, use double quotes if the alias has a space or a command line argument:

c:\dev> git config --global alias.ci "commit -v"

The alias command even accepts functions as parameters. Take a look at aliases.

I think you are looking for the Jquery Load function. You would just use that function with an onclick function tied to the a tag or a button if you like.

There is no need to use angular http, you can get with js native functions

// you will ned this function to fetch the image blob._x000D_
async function getImage(url, fileName) {_x000D_
     // on the first then you will return blob from response_x000D_

    .then((blob) => { // on the second, you just create a file from that blob, getting the type and name that intend to inform_x000D_
         _x000D_
        return new File([blob], fileName+'.'+   blob.type.split('/')[1]) ;_x000D_

Easier if the input is a string, we can use split()

decimal = input("Input decimal number: ") #123.456

# split 123.456 by dot = ['123', '456']
after_coma = decimal.split('.')[1] 

# because only index 1 is taken then '456'
print(after_coma) # '456'

if you want to make a number type print(int(after_coma)) # 456

A query's projection can only have one instance of a given name. As your WHERE clause shows, you have several tables with a column called ID. Because you are selecting * your projection will have several columns called ID. Or it would have were it not for the compiler hurling ORA-00918.

The solution is quite simple: you will have to expand the projection to explicitly select named columns. Then you can either leave out the duplicate columns, retaining just (say) COACHES.ID or use column aliases: coaches.id as COACHES_ID.

Perhaps that strikes you as a lot of typing, but it is the only way. If it is any comfort, SELECT * is regarded as bad practice in production code: explicitly named columns are much safer.

The read(1) utility along with output redirection of the ls(1) command will do what you want.

The correct value for the content attribute should include initial-scale instead:

<meta name="viewport" content="width=device-width, initial-scale=1">_x000D_
                                                   ^^^^^^^^^^^^^^^

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

The other answers given here work well since you use the same renderer in every column.

However, I tend to believe that generally when using a JTable you will have different types of data in each columm and therefore you won't be using the same renderer for each column. In these cases you may find the Table Row Rendering approach helpfull.

If only the columns are required then DataTable.Clone() can be used. With Clone function only the schema will be copied. But DataTable.Copy() copies both the structure and data

E.g.

DataTable dt = new DataTable();
dt.Columns.Add("Column Name");
dt.Rows.Add("Column Data");
DataTable dt1 = dt.Clone();
DataTable dt2 = dt.Copy();

dt1 will have only the one column but dt2 will have one column with one row.

for me, this worked

exec utl_mail.send@myotherdb(
  sender => '[email protected]',recipients => '[email protected], 
  cc => null, subject => 'my subject', message => 'my message'
); 

Apparently there is a Powershell bug in Windows 10 version 1511.

None of the fixes listed here worked for me. (or only worked temporarily)

I fixed it (both in VS2013 and VS2015) by installing version 1607. It can be downloaded here: Windows 10 Anniversary Update.

Nuget issue: https://github.com/NuGet/Home/issues/3352

If you want to extract the files to the respective folder you can try this

find . -name "*.zip" | while read filename; do unzip -o -d "`dirname "$filename"`" "$filename"; done;

A multi-processed version for systems that can handle high I/O:

find . -name "*.zip" | xargs -P 5 -I fileName sh -c 'unzip -o -d "$(dirname "fileName")/$(basename -s .zip "fileName")" "fileName"'

Iterate over the codes array using a loop, asking for each of the elements if it's equals() to usercode. If one element is equal, you can stop and handle that case. If none of the elements is equal to usercode, then do the appropriate to handle that case. In pseudocode:

found = false
foreach element in array:
  if element.equals(usercode):
    found = true
    break

if found:
  print "I found it!"
else:
  print "I didn't find it"

Here's another alternative. Assuming you have an indexed DATE or DATETIME type field, this should use the index as the formatted dates will be type converted before the index is used. You should then see a range query rather than an index query when viewed with EXPLAIN.

SELECT
    * 
FROM
    table
WHERE 
    date_created >= DATE_FORMAT( CURRENT_DATE - INTERVAL 1 MONTH, '%Y/%m/01' ) 
AND
    date_created < DATE_FORMAT( CURRENT_DATE, '%Y/%m/01' )

[None of the answers works properly above !]

I have a case of multiple key-value replacement in one file around 1000 lines. And after replacement the file structure should keep the same. for example:

.     .
key1000=value_tobe_replaced1000

I've tried:

1. the voted answer from @elmotec for massedit.

2. answer from @Cecil Curry.

3. answer from @Keithel.

The three answers definitely helped me a lot but after test I found it costs nearly 40-50s for 1st and 2ed. 3rd is not suitable for multi-replacement so I fixed it.

Notice: refer to the answers before go on.

shutil.copystat(abs_keypair_file, tmp_file.name)
shutil.move(tmp_file.name, abs_keypair_file)

time_costs = datetime.datetime.now() - start_time
print 'time costs: %s' % time_costs

time costs: 0:00:42.533879

file replacement mode:

start_time = datetime.datetime.now()
with tempfile.NamedTemporaryFile(mode='w', delete=False) as tmp_file:
    with open(abs_keypair_file) as kf:
        text = kf.read()
        for (key, value) in tuple_list:
            text = re.sub(patten, value, text, flags=re.M|re.I)
        tmp_file.write(text)
shutil.copystat(abs_keypair_file, tmp_file.name)
shutil.move(tmp_file.name, abs_keypair_file)

time_costs = datetime.datetime.now() - start_time
print 'time costs: %s' % time_costs

time costs: 0:00:00.348458

So I suggest if you match my case and your file size is not too large you may follow file replacement mode.

How to replace if file size is huge? I have no idea.

Hope this helps.

Maybe you need unique temporary file?

import tempfile

f = tempfile.NamedTemporaryFile(mode='w+b', delete=False)

print f.name
f.close()

f is opened file. delete=False means do not delete file after closing.

If you need control over the name of the file, there are optional prefix=... and suffix=... arguments that take strings. See https://docs.python.org/3/library/tempfile.html.

You can have a Windows 10 configuration with and without Hyper-V as follows in an Admin prompt:

bcdedit /copy {current} /d "Windows 10 no Hyper-V"

find the new id of the just created "Windows 10 no Hyper-V" bootentry, eg. {094a0b01-3350-11e7-99e1-bc5ec82bc470}

bcdedit /set {094a0b01-3350-11e7-99e1-bc5ec82bc470} hypervisorlaunchtype Off

After rebooting you can choose between Windows 10 with and without Hyper-V at startup

You have to use the right character encoding to accomplish this effect. You could try with •

Update

Just to clarify: use setText("\u2022 Bullet"); to add the bullet programmatically. 0x2022 = 8226

Here are some dplyr options:

# sample data
df <- data.frame(a = c('1', NA, '3', NA), b = c('a', 'b', 'c', NA), c = c('e', 'f', 'g', NA))

library(dplyr)

# remove rows where all values are NA:
df %>% filter_all(any_vars(!is.na(.)))
df %>% filter_all(any_vars(complete.cases(.)))  


# remove rows where only some values are NA:
df %>% filter_all(all_vars(!is.na(.)))
df %>% filter_all(all_vars(complete.cases(.)))  

# or more succinctly:
df %>% filter(complete.cases(.))  
df %>% na.omit

# dplyr and tidyr:
library(tidyr)
df %>% drop_na

If you are "Rebasing", "Already started rebase" which you want to cancel, just comment (#) all commits listed in rebase editor.

As a result you will get a command line message

Nothing to do

git reset --soft is just for that: it is like git reset --hard, but doesn't touch the files.

I'm running Ubuntu under WSL(Windows Subsystem for Linux) and systemctl start rsyslog didn't work for me.

So what I did is this:

$ service rsyslog start

Now syslog file will appear at /var/log/

One basic way that comes to mind would be to put the item into a table and have two cells, one with the text, the other with the image, and use style="valign:center" with the tags.

This is the perfect answer for difference between Cloud Computing and Grid Computing ? Check this:

Try this. hope this will help.

    String cls0;
    String cls1;

    Scanner in = new Scanner(System.in);  
    System.out.println("Enter a string");  
    cls0 = in.nextLine();  

    System.out.println("Enter a string");  
    cls1 = in.nextLine(); 

You can also specify the exact values for each gr

0 2,10,12,14,16,18,20 * * *

It stands for 2h00, 10h00, 12h00 and so on, till 20h00.

From the above answer, we have:

The comma, ",", means "and". If you are confused by the above line, remember that spaces are the field separators, not commas.

And from (Wikipedia page):

*    *    *    *    *  command to be executed
-    -    -    -    -
¦    ¦    ¦    ¦    ¦

¦    ¦    +--------------- day of month (1 - 31)
¦    +-------------------- hour (0 - 23)
+------------------------- min (0 - 59)

Hope it helps :)

EDIT:

• don't miss the 1st 0 (zero) and the following space: it means "the minute zero", you can also set it to 15 (the 15th minute) or expressions like */15 (every minute divisible by 15, i.e. 0,15,30)

Backup a single table with its data from a database in sql server 2008

SELECT * INTO  [dbo].[tbl_NewTable] 
FROM [dbo].[tbl_OldTable]

Chr(Number) should work for you.

select 'Hello' || chr(10) ||' world' from dual

Remember different platforms expect different new line characters:

• CHR(10) => LF, line feed (unix)
• CHR(13) => CR, carriage return (windows, together with LF)

This works for Oracle and SQL Server (you might be able to get it to work on another RDBMS):

select sum(case when a is null then 1 else 0 end) count_nulls
     , count(a) count_not_nulls 
  from us;

Or:

select count(*) - count(a), count(a) from us;

Kotlin

First Activity

startActivity(Intent(this, SecondActivity::class.java)
  .putExtra("key", "value"))

Second Activity

val value = getIntent().getStringExtra("key")

Suggestion

Always put keys in constant file for more managed way.

companion object {
    val PUT_EXTRA_USER = "user"
}
startActivity(Intent(this, SecondActivity::class.java)
  .putExtra(PUT_EXTRA_USER, "value"))

If you will place your definitions in this order then the code will be compiled

class Ball;

class Player {
public:
    void doSomething(Ball& ball);
private:
};

class Ball {
public:
    Player& PlayerB;
    float ballPosX = 800;
private:

};

void Player::doSomething(Ball& ball) {
    ball.ballPosX += 10;                   // incomplete type error occurs here.
}

int main()
{
}

The definition of function doSomething requires the complete definition of class Ball because it access its data member.

In your code example module Player.cpp has no access to the definition of class Ball so the compiler issues an error.

I have had a similar problem and this is how i solved it using the examples above:

 $(".ms-drop").click(function () {
        $(function showSelectedValues() {
            alert($(".ms-drop input[type=checkbox]:checked").map(
               function () { return this.value; }).get().join(","));
        });
    });

I have written a beautiful, nested select. Maybe it will help you.

}

    const executer = parent.attr('executer');
    if (executer) {

      event.value = value;
      event.title = title;
      event.option = $(this);
      event.select = parent;
      window[executer].apply(null, [event]);
    }
    parent.attr('value', value);

It is technically approved that MD5 is faster than SHA256 so in just verifying file integrity it will be sufficient and better for performance.

You are able to checkout the following resources:

• Speed Comparison of Popular Crypto Algorithms
• Comparison of cryptographic hash functions

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

Returning an empty or zero-length string (e.g. "") to make a cell appear blank is a common practise in a worksheet formula but recreating that option when inserting the formula through the Range.Formula or Range.FormulaR1C1 property in VBA is unwieldy due to the necessity of having to double-up the double-quote characters within a quoted string.

The worksheet's native TEXT function can produce the same result without using quotes.

'formula to insert into C1 - =IF(A1<>"", B1, "")
range("C1").formula = "=IF(A1<>"""", B1, """")"         '<~quote chars doubled up
range("C1").formula = "=IF(A1<>TEXT(,), B1, TEXT(,))"   '<~with TEXT(,) instead

To my eye, using TEXT(,) in place of "" cleans up even a simple formula like the one above. The benefits become increasingly significant when used in more complicated formulas like the practise of appending an empty string to a VLOOKUP to avoid returning a zero to the cell when a lookup results in a blank or returning an empty string on no-match with IFERROR.

'formula to insert into D1 - =IFERROR(VLOOKUP(A1, B:C, 2, FALSE)&"", "")
range("D1").formula = "=IFERROR(VLOOKUP(A1, B:C, 2, FALSE)&"""", """")"
range("D1").formula = "=IFERROR(VLOOKUP(A1, B:C, 2, FALSE)&TEXT(,), TEXT(,))"

With TEXT(,) replacing the old "" method of delivering an empty string, you might get to stop using an abacus to determine whether you have the right number of quote characters in a formula string.

References are NOT a guarantee of getting a non-null pointer. (Though we often treat them as such.)

While horrifically bad code, as in take you out behind the woodshed bad code, the following will compile & run: (At least under my compiler.)

bool test( int & a)
{
  return (&a) == (int *) NULL;
}

int
main()
{
  int * i = (int *)NULL;
  cout << ( test(*i) ) << endl;
};

The real issue I have with references lies with other programmers, henceforth termed IDIOTS, who allocate in the constructor, deallocate in the destructor, and fail to supply a copy constructor or operator=().

Suddenly there's a world of difference between foo(BAR bar) and foo(BAR & bar). (Automatic bitwise copy operation gets invoked. Deallocation in destructor gets invoked twice.)

Thankfully modern compilers will pick up this double-deallocation of the same pointer. 15 years ago, they didn't. (Under gcc/g++, use setenv MALLOC_CHECK_ 0 to revisit the old ways.) Resulting, under DEC UNIX, in the same memory being allocated to two different objects. Lots of debugging fun there...

More practically:

• References hide that you are changing data stored someplace else.
• It's easy to confuse a Reference with a Copied object.
• Pointers make it obvious!

sp_spaceused gives you the size of all the indexes combined.

If you want the size of each index for a table, use one of these two queries:

SELECT
    i.name                  AS IndexName,
    SUM(s.used_page_count) * 8   AS IndexSizeKB
FROM sys.dm_db_partition_stats  AS s 
JOIN sys.indexes                AS i
ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id
WHERE s.[object_id] = object_id('dbo.TableName')
GROUP BY i.name
ORDER BY i.name

SELECT
    i.name              AS IndexName,
    SUM(page_count * 8) AS IndexSizeKB
FROM sys.dm_db_index_physical_stats(
    db_id(), object_id('dbo.TableName'), NULL, NULL, 'DETAILED') AS s
JOIN sys.indexes AS i
ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id
GROUP BY i.name
ORDER BY i.name

The results are usually slightly different but within 1%.

You can try this one

CONVERT(DATE, GETDATE()) = CONVERT(DATE,'2017-11-16 21:57:20.000')

I test that for MS SQL 2014 by following code

select case when CONVERT(DATE, GETDATE()) = CONVERT(DATE,'2017-11-16 21:57:20.000') then 'ok'
            else '' end

you can do:

<div style="float: left;"></div>

or

<div style="display: inline;"></div>

Either one will cause the divs to tile horizontally.

You have to add the row explicitly to the table

table.Rows.Add(row);

if you happened on CentOS?

You should try to this.

$ service network restart

or

reboot your server.

There are multiple number groups and some particular numbers that will never be allocated:

• Numbers with all zeros in any digit group (000-xx-####, ###-00-####, ###-xx-0000).
• Numbers with an area group (first three digits) of 666 or any of 900-999.
• Numbers that have been misused in any way, such as the well known 078-05-1120.

Consider using one of these (the obviously invalid 000-00-0000 would be a good one IMO).

(Answer has been updated to provide source information beyond Wikipedia and remove information that is no longer accurate after the SSA made its randomization change in mid 2011.)

A self join is simply when you join a table with itself. There is no SELF JOIN keyword, you just write an ordinary join where both tables involved in the join are the same table. One thing to notice is that when you are self joining it is necessary to use an alias for the table otherwise the table name would be ambiguous.

It is useful when you want to correlate pairs of rows from the same table, for example a parent - child relationship. The following query returns the names of all immediate subcategories of the category 'Kitchen'.

SELECT T2.name
FROM category T1
JOIN category T2
ON T2.parent = T1.id
WHERE T1.name = 'Kitchen'

This code will help:

This function will return random string with length between $maxLength and $minLength.

NOTE: Function random_bytes works since PHP 7.

If you need specific length, so $maxLength and $minLength must be same.

function getRandomString($maxLength = 20, $minLength = 10)
{
    $minLength = $maxLength < $minLength ? $maxLength : $minLength;
    $halfMin = ceil($minLength / 2);
    $halfMax = ceil($maxLength / 2);
    $bytes = random_bytes(rand($halfMin, $halfMax));
    $randomString = bin2hex($bytes);
    $randomString = strlen($randomString) > $maxLength ? substr($randomString, 0, -1) : $randomString;
    return $randomString;
}

You need to use the 'g' switch for a global search

var result = mystring.match(/(&|&)?([^=]+)=([^&]+)/g)

$('#myDiv').text()

Although you'd be better off doing something like:

var txt = $('#myDiv p').text();_x000D_
alert(txt);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myDiv"><p>Some Text</p></div>

Make sure you're linking to your jQuery file too :)

var dictionary = (from x in y 
                  select new SomeClass
                  {
                      prop1 = value1,
                      prop2 = value2
                  }
                  ).ToDictionary(item => item.prop1);

That's assuming that SomeClass.prop1 is the desired Key for the dictionary.

you can also use the show command.

show tables like '%tableName%'

The latest version from Red Gate is 6.1. However the 5.1 version cannot automatically update to version 6 because there were changes to the Terms of Service, so instead you are redirected to the site to download the 6.1 version. This is mostly because of legal reasons as you can check in the following post:

Oi! What's going on with the .NET Reflector update mechanism?

After you manually update to 6.1 you will no longer experience any problems.

While indexOf() works perfectly, it only returns one index.

I was looking for an elegant way to get an array of indexes for elements which satisfy some condition.

Here is how it can be done:

Swift 3:

let array = ["apple", "dog", "log"]

let indexes = array.enumerated().filter {
    $0.element.contains("og")
    }.map{$0.offset}

print(indexes)

Swift 2:

let array = ["apple", "dog", "log"]

let indexes = array.enumerate().filter {
    $0.element.containsString("og")
    }.map{$0.index}

print(indexes)

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

By default p tags are block elements, which means they take 100% of the parent width.

You can change their display property with:

#container p {
   display:inline-block;
}

But it puts the elements side by side.

To keep each element on its own line you can use:

#container p {
   clear:both;
   float:left;
}

_{(If you use float and need to clear after floated elements, see this link for different techniques: http://css-tricks.com/all-about-floats/)}

Demo: http://jsfiddle.net/CvJ3W/5/

Edit

If you go for the solution with display:inline-block but want to keep each item in one line, you can just add a <br> tag after each one:

<div id="container">
  <p>Sample Text 1</p><br/>
  <p>Sample Text 2</p><br/>
  <p>Sample Text 3</p><br/>
</div>

New demo: http://jsfiddle.net/CvJ3W/7/

I wanted to programmatically -- using only Bash -- kill the process listening on a given port.

Let's say the port is 8089, then here is how I did it:

badPid=$(netstat --listening --program --numeric --tcp | grep "::8089" | awk '{print $7}' | awk -F/ '{print $1}' | head -1)
kill -9 $badPid

I hope this helps someone else! I know it is going to help my team.

Nice question, a while ago I've experimented a bit with this, but haven't used it a lot because it's still not bulletproof. I divided the plot area into a 32x32 grid and calculated a 'potential field' for the best position of a label for each line according the following rules:

• white space is a good place for a label
• Label should be near corresponding line
• Label should be away from the other lines

The code was something like this:

        plt.title(axis.lines[l].get_label())

        pos = np.argmax(p)  # note, argmax flattens the array first 
        best_x, best_y =  (pos / N, pos % N) 
        x = xmin + (xmax-xmin) * best_x / N       
        y = ymin + (ymax-ymin) * best_y / N       


        axis.text(x, y, axis.lines[l].get_label(), 
                  horizontalalignment='center',
                  verticalalignment='center')


plt.close('all')

plt.plot(x, y2, 'r', label='red')
plt.plot(x, y3, 'g', label='green')

mysqld.exe was using 480 mb in RAM. I found that I added this parameter to my.ini

table_definition_cache = 400

that reduced memory usage from 400,000+ kb down to 105,000kb

Actually the mysql query for copy data from one table to another is

Insert into table2_name (column_names) select column_name from table1

where, the values copied from table1 to table2

Here is a static class implementing Start(), Stop(), and IsStarted() for IISExpress. It is parametrized by hard-coded static properties and passes invocation information via the command-line arguments to IISExpress. It uses the Nuget package, MissingLinq.Linq2Management, which surprisingly provides information missing from System.Diagnostics.Process, specifically, the command-line arguments that can then be used to help disambiguate possible multiple instances of IISExpress processes, since I don't preserve the process Ids. I presume there is a way to accomplish the same thing with just System.Diagnostics.Process, but life is short. Enjoy.

Devise uses some generators to generate views and stuff it needs into your application. If you have run this generator, you can easily undo it with

rails destroy <name_of_generator>

The uninstallation of the gem works as described in the other posts.

^CTR.*$

matches a line starting with CTR.

You can do that on javascript side .

<input type="submit" value="Send It!" onClick="return ActionDeterminator();">

When clicked, the JavaScript function ActionDeterminator() determines the alternate action URL. Example code.

function ActionDeterminator() {
  if(document.myform.reason[0].checked == true) {
    document.myform.action = 'http://google.com';
  }
  if(document.myform.reason[1].checked == true) {
    document.myform.action = 'http://microsoft.com';
    document.myform.method = 'get';
  }
  if(document.myform.reason[2].checked == true) {
    document.myform.action = 'http://yahoo.com';
  }
  return true;
}

When debugging lines of code, here are the usual scenarios:

• (Step Into) A method is about to be invoked, and you want to debug into the code of that method, so the next step is to go into that method and continue debugging step-by-step.
• (Step Over) A method is about to be invoked, but you're not interested in debugging this particular invocation, so you want the debugger to execute that method completely as one entire step.
• (Step Return) You're done debugging this method step-by-step, and you just want the debugger to run the entire method until it returns as one entire step.
• (Resume) You want the debugger to resume "normal" execution instead of step-by-step
• (Line Breakpoint) You don't care how it got there, but if execution reaches a particular line of code, you want the debugger to temporarily pause execution there so you can decide what to do.

Eclipse has other advanced debugging features, but these are the basic fundamentals.

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

It doesn't work because it doesn't make sense (so little sense that HTML 5 explicitly forbids it).

To fix it, decide if you want a link or a submit button and use whichever one you actually want (Hint: You don't have a form, so a submit button is nonsense).

You can also set the 'dashed' option when setting your terminal, for instance:

set term pdf dashed

if you have an array

var subcategories=[{name:"test",desc:"test"}];

function hasCategory(nameStr) {
        for(let i=0;i<subcategories.length;i++){
            if(subcategories[i].name===nameStr){
                return true;
            }
        }
        return false;
    }

if you have an object

var category={name:"asd",test:""};

if(category.hasOwnProperty('name')){//or category.name!==undefined
   return true;
}else{
   return false;
}

Workaround:

1. Open your solution in Visual Web Developer Express. It will not load some of the projects in the solution but it is ok.
2. Make a new connection in Database Explorer to the required database from SQL Server.
3. Add a new class library project.
4. Add a LINQ to SQL Classes item and link it to your database.
5. Close the solution.
6. Open the solution in Visual C# Express.

Now you have a LINQ to SQL classes library that is linked to your SQL Server database in Visual C# Express.

Update

The solution is for Visual Studio Express 2010.

VanillaJS === JavaScript i.e.VanillaJS is native JavaScript

Why, Vanilla says it all!!!

Computer software, and sometimes also other computing-related systems like computer hardware or algorithms, are called vanilla when not customized from their original form, meaning that they are used without any customization or updates applied to them (Refer this article). So Vanilla often refers to pure or plain.

In the English language Vanilla has a similar meaning, In information technology, vanilla (pronounced vah-NIHL-uh ) is an adjective meaning plain or basic. Or having no special or extra features, ordinary or standard.

So why name it VanillaJS? As the accepted answer says some bosses want to work with a framework (because it's more organized and flexible and do all the things we want??) but simply JavaScript will do the job. Yet you need to add a framework somewhere. Use VanillaJS...

Is it a Joke? YES

Want some fun? Where can you find it, http://vanilla-js.com/ Download and see for yourself!!! It's 0 bytes uncompressed, 25 bytes gzipped :D

Found this pun on internet regarding JS frameworks (Not to condemn the existing JS frameworks though, they'll make life really easy :)),

Two solutions for this:

1. PHP function nl2br():

   e.g.,

   echo nl2br("This\r\nis\n\ra\nstring\r");
   
   // will output
   This<br />
   is<br />
   a<br />
   string<br />
   

2. Wrap the input in <pre></pre> tags.

   See: W3C Wiki - HTML/Elements/pre

Use myList.get(3) to get access to the current object and modify it, assuming instances of Customer have a way to be modified.

Solved the problem with:

sudo chown -R $USER:$USER /var/www/folder-name

sudo chmod -R 755 /var/www

Grant permissions

Tested alone, <select class=input-xxlarge> sets the content width of the element to 530px. (The total width of the element is slightly smaller than that of <input class=input-xxlarge> due to different padding. If this a a problem, set the paddings in your own style sheet as desired.)

So if it does not work, the effect is prevented by some setting in your own style sheet or maybe in the use other settings for the element.

The popular answer google.maps.event.trigger(map, "resize"); didn't work for me alone.

Here was a trick that assured that the page had loaded and that the map had loaded as well. By setting a listener and listening for the idle state of the map you can then call the event trigger to resize.

$(document).ready(function() {
    google.maps.event.addListener(map, "idle", function(){
        google.maps.event.trigger(map, 'resize'); 
    });
}); 

This was my answer that worked for me.

Just return any kind of list. ArrayList will be fine, its not static.

    ArrayList<yourClass> list = new ArrayList<yourClass>();
for (yourClass item : yourArray) 
{
   list.add(item); 
}

If you want to pass a Uri to another activity, try the method intent.setData(Uri uri) https://developer.android.com/reference/android/content/Intent.html#setData(android.net.Uri)

In another activity, via intent.getData() to obtain the Uri.

This worked for me:

var xdoc = new XmlDocument { XmlResolver = null };  
xdoc.LoadXml(xmlFragment);

Just Use this oneliner:

divisions.Items.FindByText("Some Text").Selected = true;
divisions.Items.FindByValue("some value").Selected = true;

where divisions is a dropdownlist control.

Hope it helps someone.

In my case, I needed to set QUOTED_IDENTIFIER on. This led to a slight modification of Mark Rendle's answer above:

EXEC sp_MSForEachTable 'DISABLE TRIGGER ALL ON ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable 'SET QUOTED_IDENTIFIER ON; DELETE FROM ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable 'ENABLE TRIGGER ALL ON ?'
GO

There are two things,

1) You can run the mongodb instance without username and password first.

2) Then you can add the user to the system database of the mongodb which is default one using the query below.

db.createUser({
  user: "myUserAdmin",
  pwd: "abc123",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})

Thanks.

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

I could do this (demo):

<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
</head>
<body>
    <form >
        <input type="file" id="f" data-max-size="32154" />
        <input type="submit" />
    </form>
<script>
$(function(){
    $('form').submit(function(){
        var isOk = true;
        $('input[type=file][data-max-size]').each(function(){
            if(typeof this.files[0] !== 'undefined'){
                var maxSize = parseInt($(this).attr('max-size'),10),
                size = this.files[0].size;
                isOk = maxSize > size;
                return isOk;
            }
        });
        return isOk;
    });
});
</script>
</body>
</html>

And if push --force doesn't work you can do push --delete. Look at 2^nd line on this instance:

git reset --hard HEAD~3  # reset current branch to 3 commits ago
git push origin master --delete  # do a very very bad bad thing
git push origin master  # regular push

But beware...

Never ever go back on a public git history!

In other words:

• Don't ever force push on a public repository.
• Don't do this or anything that can break someone's pull.
• Don't ever reset or rewrite history in a repo someone might have already pulled.

Of course there are exceptionally rare exceptions even to this rule, but in most cases it's not needed to do it and it will generate problems to everyone else.

Do a revert instead.

And always be careful with what you push to a public repo. Reverting:

git revert -n HEAD~3..HEAD  # prepare a new commit reverting last 3 commits
git commit -m "sorry - revert last 3 commits because I was not careful"
git push origin master  # regular push

In effect, both origin HEADs (from the revert and from the evil reset) will contain the same files.

edit to add updated info and more arguments around push --force

Consider pushing force with lease instead of push, but still prefer revert

Another problem push --force may bring is when someone push anything before you do, but after you've already fetched. If you push force your rebased version now you will replace work from others.

git push --force-with-lease introduced in the git 1.8.5 (thanks to @VonC comment on the question) tries to address this specific issue. Basically, it will bring an error and not push if the remote was modified since your latest fetch.

This is good if you're really sure a push --force is needed, but still want to prevent more problems. I'd go as far to say it should be the default push --force behaviour. But it's still far from being an excuse to force a push. People who fetched before your rebase will still have lots of troubles, which could be easily avoided if you had reverted instead.

And since we're talking about git --push instances...

Why would anyone want to force push?

@linquize brought a good push force example on the comments: sensitive data. You've wrongly leaked data that shouldn't be pushed. If you're fast enough, you can "fix"* it by forcing a push on top.

* The data will still be on the remote unless you also do a garbage collect, or clean it somehow. There is also the obvious potential for it to be spread by others who'd fetched it already, but you get the idea.

There are many different sytles/conventions that people use when coding C++. For example, some people prefer separating words using capitals (myVar or MyVar), or using underscores (my_var). Typically, variables that use underscores are in all lowercase (from my experience).
There is also a coding style called hungarian, which I believe is used by microsoft. I personally believe that it is a waste of time, but it may prove useful. This is were variable names are given short prefixes such as i, or f to hint the variables type. For example: int iVarname, char* strVarname.

It is accepted that you end a struct/class name with _t, to differentiate it from a variable name. E.g.:

class cat_t {
  ...
};

cat_t myCat;

It is also generally accepted to add a affix to indicate pointers, such as pVariable or variable_p.

In all, there really isn't any single standard, but many. The choices you make about naming your variables doesn't matter, so long as it is understandable, and above all, consistent. Consistency, consistency, CONSISTENCY! (try typing that thrice!)

And if all else fails, google it.

To just get the list of the changed files with the paths, use

svn diff --summarize -r<rev-of-commit>:<rev-of-commit - 1>

For example:

svn diff --summarize -r42:41

should result in something like

M       path/to/modifiedfile
A       path/to/newfile

interface

uses
  Classes;

type
  TStringArray = array of string;

  TUtilStr = class
    class function Split(const AValue: string; const ADelimiter: Char = ';'; const AQuoteChar: Char = '"'): TStringArray; static;
  end;


implementation

{ TUtilStr }

class function TUtilStr.Split(const AValue: string; const ADelimiter: Char; const AQuoteChar: Char): TStringArray;
var
  LSplited: TStringList;
  LText: string;
  LIndex: Integer;
begin
  LSplited := TStringList.Create;
  try
    LSplited.StrictDelimiter := True;
    LSplited.Delimiter := ADelimiter;
    LSplited.QuoteChar := AQuoteChar;
    LSplited.DelimitedText := AValue;

    SetLength(Result, LSplited.Count);
    for LIndex := 0 to LSplited.Count - 1 do
    begin
      Result[LIndex] := LSplited[LIndex];
    end;
  finally
    LSplited.Free;
  end;
end;

end.

You can use the Accord.NET framework for this. It provides a few different methods of resizing:

• Bicubic
• Bilinear
• Nearest Neighbour
