Old question, but I should note that the general task of parsing XLS files from javascript is tedious and difficult but not impossible.

I have basic parsers implemented in pure JS:

• http://oss.sheetjs.com/js-xls/ (XLS files, what you wanted)
• http://oss.sheetjs.com/js-xlsx/ (XLSX/XLSM/XLSB files)

Both pages are HTML5 File API-driven XLS/XLSX parsers (you can drag-drop your file and it will print out the data in the cells in a comma-separated list). You can also generate JSON objects (assuming the first row is a header row).

The test suite http://oss.sheetjs.com/ shows a version that uses XHR to get and parse files.

I'm late, but:

BufferReader.java:

public BufferedReader(Reader in) {
  this(in, defaultCharBufferSize);
}

(...)

public void close() throws IOException {
    synchronized (lock) {
        if (in == null)
            return;
        try {
            in.close();
        } finally {
            in = null;
            cb = null;
        }
    }
}

The basic setup of decorators is like this:

InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);

The key issue in this snippet is the value of encoding. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.

For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.

Most network protocols use a header or other metadata to explicitly note the character encoding.

In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.

Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

SELECT x.name, x.summary, (x.summary / COUNT(*)) as percents_of_total
FROM tbl t
INNER JOIN 
(SELECT name, SUM(value) as summary
FROM tbl
WHERE year BETWEEN 2000 AND 2001
GROUP BY name) x ON x.name = t.name
GROUP BY x.name, x.summary

try something like this

<script type="text/javascript">
function PopUp(hideOrshow) {
    if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
    else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
    setTimeout(function () {
        PopUp('show');
    }, 5000);
}
</script>

and your html

<div id="ac-wrapper" style='display:none'>
    <div id="popup">
        <center>
             <h2>Popup Content Here</h2>    
            <input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
        </center>
    </div>
</div>

Demo JsFiddle

First of all, set more safe initial data:

getInitialState : function() {
    return {data: {comments:[]}};
},

And ensure your ajax data.

It should work if you follow above two instructions like Demo.

Updated: you can just wrap the .map block with conditional statement.

if (this.props.data) {
  var commentNodes = this.props.data.map(function (comment){
      return (
        <div>
          <h1>{comment.author}</h1>
        </div>
      );
  });
}

Just one line code to omit Array duplicates without effecting order:

let filteredArr = Array(NSOrderedSet(array: yourArray))

You can use a variable and change the variable instead.

````setInterval([the function], [the variable])```

Another solution is to monitor processes via the proc filesystem (safer than ps/grep combo); when you start a process it has a corresponding folder in /proc/$pid, so the solution could be

#!/bin/bash
....
doSomething &
local pid=$!
while [ -d /proc/$pid ]; do # While directory exists, the process is running
    doSomethingElse
    ....
else # when directory is removed from /proc, process has ended
    wait $pid
    local exit_status=$?
done
....

Now you can use the $exit_status variable however you like.

You could do it like below.

$array = array(
   "a" => "apple",
   "b" => "banana",
   "c" => "catnip"
);

foreach ($array as $a_key => $a_val) {
   $json .= "\"{$a_key}\" : \"{$a_val}\",\n";
}

header('Content-Type: application/json');
echo "{\n"  .rtrim($json, ",\n") . "\n}";

Above would output kind of like Facebook.

{
"a" : "apple",
"b" : "banana",
"c" : "catnip"
}

This worked for me

let exampleArray = [1, 2, 3, 4, 5];
let exampleToString = exampleArray.toString(); //convert to toString
let query = `Select * from table_name where column_name in (${exampleToString})`; //Execute the query to get response

I have got the same problem, then after an hour of effort I got to know that the array should not be directly accessed in the query. So I then found that the data should be sent in the paranthesis it self, then again I have converted that array to string using toString method in js. So I have worked by executing the above query and got my expected result

None of answered method solve the problem which log4j.properties file is not found for non-maven jsf web project in NetBeans. So the answer is:

1. Create a folder named resources in project root folder (outermost folder).
2. Right click project in projects explorer in left menu, select properties.
3. Open Sources in Categories, add that folder in Source Package Folders.
4. Open Run in Categories and add this to VM options: Dlog4j.configuration=resources/log4j.properties
5. Click Ok, build and deploy project as you like, that's it.

I wrote special pattern in log4j file to check whether log4j is used my file:

# Root Logger Option
log4j.rootLogger=INFO, console

# Redirect Log Messages To Console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-5p | %d{yyyy-MM-dd HH:mm:ss} | [%t] %C{2} xxxx (%F:%L) - %m%n

I checked it because if you use BasicConfigurator.configure(); in your code in log4j use predefined pattern.

If your computer is a 64bit, all you need to do is uninstall your Java x86 version and install a 64bit version. I had the same problem and this worked. Nothing further needs to be done.

Use this instead:

new StreamWriter("c:\\file.txt", true);

With this overload of the StreamWriter constructor you choose if you append the file, or overwrite it.

C# 4 and above offers the following syntax, which some find more readable:

new StreamWriter("c:\\file.txt", append: true);

1. update your version of youtube-dl to the lastest as older version might not support palylists.

   sudo youtube-dl -U if u installed via .deb

   sudo pip install --upgrade youtube_dl via pip

2. use this to download the playlist as an MP3 file

   youtube-dl --extract-audio --audio-format mp3 #url_to_playlist

Use, a global variable or property for assigning the value to the textbox, give the value for the variable in another class and assign it to the textbox.text in form class.

The background-size property is ie>=9 only, but if that is fine with you, you can use a div with background-image and set background-size: contain:

div.image{
    background-image: url("your/url/here");
    background-size: contain;
    background-repeat: no-repeat;
    background-position: center;
}

Now you can just set your div size to whatever you want and not only will the image keep its aspect ratio it will also be centralized both vertically and horizontally within the div. Just don't forget to set the sizes on the css since divs don't have the width/height attribute on the tag itself.

This approach is different than setecs answer, using this the image area will be constant and defined by you (leaving empty spaces either horizontally or vertically depending on the div size and image aspect ratio), while setecs answer will get you a box that exactly the size of the scaled image (without empty spaces).

Edit: According to the MDN background-size documentation you can simulate the background-size property in IE8 using a proprietary filter declaration:

Though Internet Explorer 8 doesn't support the background-size property, it is possible to emulate some of its functionality using the non-standard -ms-filter function:

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='path_relative_to_the_HTML_file', sizingMethod='scale')";

The answer given by @7-isnotbad is extremely close, but doesn't count single-word lines. Here's the fix, which seems to account for every possible combination of words, spaces and newlines.

function countWords(s){
    s = s.replace(/\n/g,' '); // newlines to space
    s = s.replace(/(^\s*)|(\s*$)/gi,''); // remove spaces from start + end
    s = s.replace(/[ ]{2,}/gi,' '); // 2 or more spaces to 1
    return s.split(' ').length; 
}

Try this::

sb_trim = Regex.Replace(stw, @"(\D+)\s+\$([\d,]+)\.\d+\s+(.)",
    m => string.Format(
        "{0},{1},{2}",
        m.Groups[1].Value,
        m.Groups[2].Value.Replace(",", string.Empty),
        m.Groups[3].Value));

This is about as clean an answer as you'll get, at least with regexes.

• (\D+): First capture group. One or more non-digit characters.
• \s+\$: One or more spacing characters, then a literal dollar sign ($).
• ([\d,]+): Second capture group. One or more digits and/or commas.
• \.\d+: Decimal point, then at least one digit.
• \s+: One or more spacing characters.
• (.): Third capture group. Any non-line-breaking character.

The second capture group additionally needs to have its commas stripped. You could do this with another regex, but it's really unnecessary and bad for performance. This is why we need to use a lambda expression and string format to piece together the replacement. If it weren't for that, we could just use this as the replacement, in place of the lambda expression:

"$1,$2,$3"

Another option is snprintf:

double pi = 3.1415926;

std::string s(16, '\0');
auto written = std::snprintf(&s[0], s.size(), "%.2f", pi);
s.resize(written);

Demo. Error handling should be added, i.e. checking for written < 0.

Appears to be resolved by Android Studio 3.0 Canary 4 and Gradle 3.0.0-alpha4.

I did not get the size of the list using length but rather size as one the answer above suggested it because of the issue reported here.

val list = List("apple", "oranges", "apple", "banana", "apple", "oranges", "oranges")
list.groupBy(x=>x).map(t => (t._1, t._2.size))

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

The "big iron" answer is generally one thread per limited resource -- processor (CPU bound), arm (I/O bound), etc -- but that only works if you can route the work to the correct thread for the resource to be accessed.

Where that's not possible, consider that you have fungible resources (CPUs) and non-fungible resources (arms). For CPUs it's not critical to assign each thread to a specific CPU (though it helps with cache management), but for arms, if you can't assign a thread to the arm, you get into queuing theory and what's optimal number to keep arms busy. Generally I'm thinking that if you can't route requests based on the arm used, then having 2-3 threads per arm is going to be about right.

A complication comes about when the unit of work passed to the thread doesn't execute a reasonably atomic unit of work. Eg, you may have the thread at one point access the disk, at another point wait on a network. This increases the number of "cracks" where additional threads can get in and do useful work, but it also increases the opportunity for additional threads to pollute each other's caches, etc, and bog the system down.

Of course, you must weigh all this against the "weight" of a thread. Unfortunately, most systems have very heavyweight threads (and what they call "lightweight threads" often aren't threads at all), so it's better to err on the low side.

What I've seen in practice is that very subtle differences can make an enormous difference in how many threads are optimal. In particular, cache issues and lock conflicts can greatly limit the amount of practical concurrency.

If the type implements IDisposable, it automatically disposes that type.

Given:

public class SomeDisposableType : IDisposable
{
   ...implmentation details...
}

These are equivalent:

SomeDisposableType t = new SomeDisposableType();
try {
    OperateOnType(t);
}
finally {
    if (t != null) {
        ((IDisposable)t).Dispose();
    }
}

using (SomeDisposableType u = new SomeDisposableType()) {
    OperateOnType(u);
}

The second is easier to read and maintain.

I simply use this jQuery trick:

$("a:focus").attr('data-id');

It gets the focused a element and gets the data-id attribute from it.

I always use store.proxy.reader.jsonData or store.proxy.reader.rawData

For example - this return the items nested into a root node called 'data':

var some_store = Ext.data.StoreManager.lookup('some_store_id');
Ext.each(some_store.proxy.reader.rawData.data, function(obj, i){
   console.info(obj);
});

This only works immediately after a store read-operation (while not been manipulated yet).

If you need to concatenate paths with quotes, you can use = to replace quotes in a variable. This does not require you to know if the path already contains quotes or not. If there are no quotes, nothing is changed.

@echo off
rem Paths to combine
set DIRECTORY="C:\Directory with spaces"
set FILENAME="sub directory\filename.txt"

rem Combine two paths
set COMBINED="%DIRECTORY:"=%\%FILENAME:"=%"
echo %COMBINED%

rem This is just to illustrate how the = operator works
set DIR_WITHOUT_SPACES=%DIRECTORY:"=%
echo %DIR_WITHOUT_SPACES%

For my WPF app, I deleted the application folder, did "Get Latest" from source control again, and rebuilt. All breakpoints working great now.

You can't directly control this, because it's an option controlled by Internet Explorer users.

Opening pages using Window.open with a different window name will open in a new browser window like a popup, OR open in a new tab, if the user configured the browser to do so.

EDIT:

A more detailed explanation:

1. In modern browsers, window.open will open in a new tab rather than a popup.

2. You can force a browser to use a new window (‘popup’) by specifying options in the 3rd parameter

3. If the window.open call was not part of a user-initiated event, it’ll open in a new window.

4. A “user initiated event” does not have to the same function call – but it must originate in the function invoked by a user click

5. If a user initiated event delegates or defers a function call (in an event listener or delegate not bound to the click event, or by using setTimeout for example), it loses it’s status as “user initiated”

6. Some popup blockers will allow windows opened from user initiated events, but not those opened otherwise.

7. If any popup is blocked, those normally allowed by a blocker (via user initiated events) will sometimes also be blocked. Some examples…

Forcing a window to open in a new browser instance, instead of a new tab:

window.open('page.php', '', 'width=1000');

The following would qualify as a user-initiated event, even though it calls another function:

function o(){
  window.open('page.php');
}
$('button').addEvent('click', o);

The following would not qualify as a user-initiated event, since the setTimeout defers it:

function g(){
  setTimeout(o, 1);
}
function o(){
  window.open('page.php');
}
$('button').addEvent('click', g);

Erm, after understanding your question: are you sure that the signature-method only creates a SHA1 and encrypts it? GPG et al offer to compress/clear sign the data. Maybe this java-signature-alg also creates a detachable/attachable signature.

This works too and you dont have to use join or anything:

DROP VIEW IF EXISTS yourview;

CREATE VIEW yourview AS
    SELECT table1.column1, 
    table2.column2
FROM 
table1, table2 
WHERE table1.column1 = table2.column1;

you can use process class it's very easy. use this namespace

using System.Diagnostics;

if you want to make a button to get active window.

private void button1_Click(object sender, EventArgs e)
    {            
       Process currentp = Process.GetCurrentProcess();
       TextBox1.Text = currentp.MainWindowTitle;  //this textbox will be filled with active window.
    }

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

to make it as globally reuse function using jquery

HTML

<select class="select_location">
   <option value="http://localhost.com/app/page1.html">Page 1</option>
   <option value="http://localhost.com/app/page2.html">Page 2</option>
   <option value="http://localhost.com/app/page3.html">Page 3</option>
</select>

Javascript using jquery

$('.select_location').on('change', function(){
   window.location = $(this).val();
});

now you will able to reuse this function by adding .select_location class to any Select element class

Create a Virtual Machine with Windows running on it and download the file to a shared folder. :-D

I had the same problem. I used a trigger and in that trigger I called a procedure which computed some values into 2 OUT variables. When I tried to print the result in the trigger body, nothing showed on screen. But then I solved this problem by making 2 local variables in a function, computed what I need with them and finally, copied those variables in your OUT procedure variables. I hope it'll be useful and successful!

Yes, using g++ command worked for me:

you can achieve that using Following example uses addBatch & executeBatch commands to execute multiple SQL commands simultaneously.

Batch Processing allows you to group related SQL statements into a batch and submit them with one call to the database. reference

When you send several SQL statements to the database at once, you reduce the amount of communication overhead, thereby improving performance.

• JDBC drivers are not required to support this feature. You should use the DatabaseMetaData.supportsBatchUpdates() method to determine if the target database supports batch update processing. The method returns true if your JDBC driver supports this feature.
• The addBatch() method of Statement, PreparedStatement, and CallableStatement is used to add individual statements to the batch. The executeBatch() is used to start the execution of all the statements grouped together.
• The executeBatch() returns an array of integers, and each element of the array represents the update count for the respective update statement.
• Just as you can add statements to a batch for processing, you can remove them with the clearBatch() method. This method removes all the statements you added with the addBatch() method. However, you cannot selectively choose which statement to remove.

EXAMPLE:

import java.sql.*;

public class jdbcConn {
   public static void main(String[] args) throws Exception{
      Class.forName("org.apache.derby.jdbc.ClientDriver");
      Connection con = DriverManager.getConnection
      ("jdbc:derby://localhost:1527/testDb","name","pass");

      Statement stmt = con.createStatement
      (ResultSet.TYPE_SCROLL_SENSITIVE,
      ResultSet.CONCUR_UPDATABLE);
      String insertEmp1 = "insert into emp values
      (10,'jay','trainee')";
      String insertEmp2 = "insert into emp values
      (11,'jayes','trainee')";
      String insertEmp3 = "insert into emp values
      (12,'shail','trainee')";
      con.setAutoCommit(false);
      stmt.addBatch(insertEmp1);//inserting Query in stmt
      stmt.addBatch(insertEmp2);
      stmt.addBatch(insertEmp3);
      ResultSet rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows before batch execution= "
      + rs.getRow());
      stmt.executeBatch();
      con.commit();
      System.out.println("Batch executed");
      rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows after batch execution= "
      + rs.getRow());
   }
}

I had to get csv files that were in subdirectories, therefore, using the response from tchlpr I modified it to work best for my use case:

print( result )

Can this not be done simply by adding a additional "container" div and adding the removed alert div back into it each time. Seems to work for me?

HTML

<div id="alert_container"></div>

JS

 $("#alert_container").html('<div id="alert"></div>');          
 $("#alert").addClass("alert alert-info  alert-dismissible");
 $("#alert").html('<a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a><strong>Info!</strong>message');

If you want everything in your post to be as $Variables you can use something like this:

foreach($_POST as $key => $value) { eval("$" . $key . " = " . $value"); }

in the DBAdaper i.e Data Base helper class declare the table like this

 private static final String USERDETAILS=
    "create table userdetails(usersno integer primary key autoincrement,userid text not null ,username text not null,password text not null,photo BLOB,visibility text not null);";

insert the values like this,

first convert the images as byte[]

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
Bitmap bitmap = ((BitmapDrawable)getResources().getDrawable(R.drawable.common)).getBitmap();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);   
byte[] photo = baos.toByteArray(); 
db.insertUserDetails(value1,value2, value3, photo,value2);

in DEAdaper class

 public long insertUserDetails(String uname,String userid, String pass, byte[] photo,String visibility) 
{
    ContentValues initialValues = new ContentValues();
    initialValues.put("username", uname);
    initialValues.put("userid",userid);

retrieve the image as follows

Cursor cur=your query;
while(cur.moveToNext())
{
     byte[] photo=cur.getBlob(index of blob cloumn);

convert the byte[] into image

ByteArrayInputStream imageStream = new ByteArrayInputStream(photo);
Bitmap theImage= BitmapFactory.decodeStream(imageStream);

I think this content may solve your problem

stdout is the standard output stream in UNIX. See http://www.gnu.org/software/libc/manual/html_node/Standard-Streams.html#Standard-Streams. When running in a terminal, you will see data written to stdout in the terminal and you can redirect it as you choose.

For example: you populated your UIPickerView with array values, then you wanted 

to select a certain array value in the first load of pickerView like "Arizona". Note that the word "Arizona" is at index 2. This how to do it :) Enjoy coding.

NSArray *countryArray =[NSArray arrayWithObjects:@"Alabama",@"Alaska",@"Arizona",@"Arkansas", nil];
UIPickerView *countryPicker=[[UIPickerView alloc]initWithFrame:self.view.bounds];
countryPicker.delegate=self;
countryPicker.dataSource=self;
[countryPicker selectRow:2 inComponent:0 animated:YES];
[self.view addSubview:countryPicker];

Archeology

itoa was a non-standard helper function designed to complement the atoi standard function, and probably hiding a sprintf (Most its features can be implemented in terms of sprintf): http://www.cplusplus.com/reference/clibrary/cstdlib/itoa.html

The C Way

Use sprintf. Or snprintf. Or whatever tool you find.

Despite the fact some functions are not in the standard, as rightly mentioned by "onebyone" in one of his comments, most compiler will offer you an alternative (e.g. Visual C++ has its own _snprintf you can typedef to snprintf if you need it).

The C++ way.

Use the C++ streams (in the current case std::stringstream (or even the deprecated std::strstream, as proposed by Herb Sutter in one of his books, because it's somewhat faster).

Conclusion

You're in C++, which means that you can choose the way you want it:

• The faster way (i.e. the C way), but you should be sure the code is a bottleneck in your application (premature optimizations are evil, etc.) and that your code is safely encapsulated to avoid risking buffer overruns.

• The safer way (i.e., the C++ way), if you know this part of the code is not critical, so better be sure this part of the code won't break at random moments because someone mistook a size or a pointer (which happens in real life, like... yesterday, on my computer, because someone thought it "cool" to use the faster way without really needing it).

textBox1.Text = "Line1" + Environment.NewLine + "Line2";

Also the markup needs to include TextMode="MultiLine" (otherwise it shows text as one line)

<asp:TextBox ID="multitxt" runat="server" TextMode="MultiLine" ></asp:TextBox>

As long as you don't want any special formatting: yes.

foreach ($_POST as $key => $value) 
    $body .= $key . ' -> ' . $value . '<br>';

Obviously, more formatting would be necessary, however that's the "easy" way. Unless I misunderstood the question.

You could also do something like this (and if you like the format, it's certainly easier):

$body = print_r($_POST, true);

Spring Tool Suite 4

Version: 4.9.0.RELEASE Build Id: 202012132054

For Mac:

You're not looping over the items. Try this instead:

$.getJSON(url, function(data){
    $.each(data.response.venue.tips.groups.items, function (index, value) {
        console.log(this.text);
    });
});

You can use either,

    int i = Convert.ToInt32(myString);

or

    int i =int.Parse(myString);

I experienced this same issue when installing Node version manager (NVM) on Windows 10.

Whenever I run the command:

npm install -g yarn

I was getting the error below:

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js'

The issue was that there other components of the previous Node installations that were interfering with the Node version manager (NVM) setup.

Here's how I fixed it:

All I had to do was to go to the Control Panel of the Windows machine.

Uninstalled Node version manager (NVM) for windows. This removed every other component and directory of the previous Node installations.

Next, I did a new installation of the Node version manager (NVM)

This time when I ran the command below everything worked fine:

npm install -g yarn

That's all.

I hope this helps

For Tomcat 8:

Linux :

Create setenv.sh and update it with following:

export SPRING_PROFILES_ACTIVE=dev

Windows:

Create setenv.bat and update it with following:

set SPRING_PROFILES_ACTIVE=dev

Probably very late to the answer but I just read this while preparing for my 70-480 exam, and found this to work -

var elem = document.getElementById('myCanvas');
elem.onclick = function() { alert("hello world"); }

Notice the event as onclick instead of onClick.

JS Bin example.

I was struggling with this too. My changes weren't being reflected in phpInfo. It wasn't until I stopped my servers and then restarted them again that my changes actually took effect.

For me i was getting this error because i needed to put the arrays in paratheses. The error is a bit tricky in this case...

ie. concatenate((a, b)) is right

not concatenate(a, b)

hope that helps.

Apple introduced the topLayoutGuide and bottomLayoutGuide as properties of UIViewController way back in iOS 7. They allowed you to create constraints to keep your content from being hidden by UIKit bars like the status, navigation or tab bar. These layout guides are deprecated in iOS 11 and replaced by a single safe area layout guide.

Refer link for more information.

Combine the answer of @mgilson and @gnibbler, I found what I need was this:

d = {"name":"interpolator",
     "children":[{'name':key,"size":value} for key,value in sample.items()]}
j = json.dumps(d, indent=4)
f = open('sample.json', 'w')
print >> f, j
f.close()

It this way, I got a pretty-print json file. The tricks print >> f, j is found from here: http://www.anthonydebarros.com/2012/03/11/generate-json-from-sql-using-python/

The current Angular Router provides Navigation Events. You can subscribe to these and make UI changes accordingly. Remember to count in other Events such as NavigationCancel and NavigationError to stop your spinner in case router transitions fail.

app.component.ts - your root component

...
import {
  Router,
  // import as RouterEvent to avoid confusion with the DOM Event
  Event as RouterEvent,
  NavigationStart,
  NavigationEnd,
  NavigationCancel,
  NavigationError
} from '@angular/router'

@Component({})
export class AppComponent {

  // Sets initial value to true to show loading spinner on first load
  loading = true

  constructor(private router: Router) {
    this.router.events.subscribe((e : RouterEvent) => {
       this.navigationInterceptor(e);
     })
  }

  // Shows and hides the loading spinner during RouterEvent changes
  navigationInterceptor(event: RouterEvent): void {
    if (event instanceof NavigationStart) {
      this.loading = true
    }
    if (event instanceof NavigationEnd) {
      this.loading = false
    }

    // Set loading state to false in both of the below events to hide the spinner in case a request fails
    if (event instanceof NavigationCancel) {
      this.loading = false
    }
    if (event instanceof NavigationError) {
      this.loading = false
    }
  }
}

app.component.html - your root view

<div class="loading-overlay" *ngIf="loading">
    <!-- show something fancy here, here with Angular 2 Material's loading bar or circle -->
    <md-progress-bar mode="indeterminate"></md-progress-bar>
</div>

Performance Improved Answer: If you care about performance there is a better method, it is slightly more tedious to implement but the performance improvement will be worth the extra work. Instead of using *ngIf to conditionally show the spinner, we could leverage Angular's NgZone and Renderer to switch on / off the spinner which will bypass Angular's change detection when we change the spinner's state. I found this to make the animation smoother compared to using *ngIf or an async pipe.

This is similar to my previous answer with some tweaks:

app.component.ts - your root component

...
import {
  Router,
  // import as RouterEvent to avoid confusion with the DOM Event
  Event as RouterEvent,
  NavigationStart,
  NavigationEnd,
  NavigationCancel,
  NavigationError
} from '@angular/router'
import {NgZone, Renderer, ElementRef, ViewChild} from '@angular/core'


@Component({})
export class AppComponent {

  // Instead of holding a boolean value for whether the spinner
  // should show or not, we store a reference to the spinner element,
  // see template snippet below this script
  @ViewChild('spinnerElement')
  spinnerElement: ElementRef

  constructor(private router: Router,
              private ngZone: NgZone,
              private renderer: Renderer) {
    router.events.subscribe(this._navigationInterceptor)
  }

  // Shows and hides the loading spinner during RouterEvent changes
  private _navigationInterceptor(event: RouterEvent): void {
    if (event instanceof NavigationStart) {
      // We wanna run this function outside of Angular's zone to
      // bypass change detection
      this.ngZone.runOutsideAngular(() => {
        // For simplicity we are going to turn opacity on / off
        // you could add/remove a class for more advanced styling
        // and enter/leave animation of the spinner
        this.renderer.setElementStyle(
          this.spinnerElement.nativeElement,
          'opacity',
          '1'
        )
      })
    }
    if (event instanceof NavigationEnd) {
      this._hideSpinner()
    }
    // Set loading state to false in both of the below events to
    // hide the spinner in case a request fails
    if (event instanceof NavigationCancel) {
      this._hideSpinner()
    }
    if (event instanceof NavigationError) {
      this._hideSpinner()
    }
  }

  private _hideSpinner(): void {
    // We wanna run this function outside of Angular's zone to
    // bypass change detection,
    this.ngZone.runOutsideAngular(() => {
      // For simplicity we are going to turn opacity on / off
      // you could add/remove a class for more advanced styling
      // and enter/leave animation of the spinner
      this.renderer.setElementStyle(
        this.spinnerElement.nativeElement,
        'opacity',
        '0'
      )
    })
  }
}

app.component.html - your root view

<div class="loading-overlay" #spinnerElement style="opacity: 0;">
    <!-- md-spinner is short for <md-progress-circle mode="indeterminate"></md-progress-circle> -->
    <md-spinner></md-spinner>
</div>

Perform the following steps:

1. Start the Registry Editor by typing regedit in the Run window.
2. Select the following key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC.
3. In the Security menu, click Permissions.
4. Grant Full Permission to the account which is being used for making connections.
5. Quit the Registry Editor.

you need to add it to Foo's prototype:

function Foo(){}
Foo.prototype.bar = function(){}
var x = new Foo()
x.bar()

I solved the issue by adding this import
More info

from past.builtins import xrange

<table style='border:1px solid black'>
    <tr>
        <td>Derp</td>
    </tr>
</table>

This should work. I use the shorthand syntax for borders.

To install Python 2.7.2 use this script - https://github.com/bngsudheer/bangadmin/blob/master/linux/centos/6/x86_64/build-python-27.sh

It also makes sure you get sqlite and readline support.

It's really a matter of opinion. In your example, System.out.println(5) would be slightly more efficient, as you only refer to the number once and never change it. As was said in a comment, int is a primitive type and not a reference - thus it doesn't take up much space. However, you might want to set actual reference variables to null only if they are used in a very complicated method. All local reference variables are garbage collected when the method they are declared in returns.

Just as a normal js object:

let myhash: IHash = {};   

myhash["somestring"] = "value"; //set

let value = myhash["somestring"]; //get

There are two things you're doing with [indexer: string] : string

• tell TypeScript that the object can have any string-based key
• that for all key entries the value MUST be a string type.

You can make a general dictionary with explicitly typed fields by using [key: string]: any;

e.g. age must be number, while name must be a string - both are required. Any implicit field can be any type of value.

As an alternative, there is a Map class:

let map = new Map<object, string>(); 

let key = new Object();

map.set(key, "value");
map.get(key); // return "value"

This allows you have any Object instance (not just number/string) as the key.

Although its relatively new so you may have to polyfill it if you target old systems.

Just set targetSdkVersion to 19. The notification icon will be colored. Then wait for Firebase to fix this issue.

I like prettyPhoto

prettyPhoto is a jQuery lightbox clone. Not only does it support images, it also support for videos, flash, YouTube, iframes and ajax. It’s a full blown media lightbox

The Instant class doesn't contain Zone information, it only stores timestamp in milliseconds from UNIX epoch, i.e. 1 Jan 1070 from UTC. So, formatter can't print a date because date always printed for concrete time zone. You should set time zone to formatter and all will be fine, like this :

Instant instant = Instant.ofEpochMilli(92554380000L);
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.SHORT).withLocale(Locale.UK).withZone(ZoneOffset.UTC);
assert formatter.format(instant).equals("07/12/72 05:33");
assert instant.toString().equals("1972-12-07T05:33:00Z");

Update to revision will only update files of your workingcopy to your choosen revision. But you cannot continue to work on this revision, as SVN will complain that your workingcopy is out of date.

revert to this revision will undo all changes in your working copy which were made after the selected revision (in your example rev. 96,97,98,99,100) Your working copy is now in modified state.

The file content of both scenarions is same, however in first case you have an unmodified working copy and you cannot commit your changes(as your workingcopy is not pointing to HEAD rev 100) in second case you have a modified working copy pointing to head and you can continue to work and commit

It is not elegant but possible to do it as one-liner <a> element

<a href onclick="event.preventDefault(); location+='&like=like'">Like</a>

Make sure that in the path to the project there is no foldername having whitespace. While creating a project the specified path folders must not contain any space in their naming.

There is a file in your git root directory named .gitignore. It's a file, not a command. You just need to insert the names of the files that you want to ignore, and they will automatically be ignored. For example, if you wanted to ignore all emacs autosave files, which end in ~, then you could add this line:

*~

If you want to remove the unwanted files from your branch, you can use git add -A, which "removes files that are no longer in the working tree".

Note: What I called the "git root directory" is simply the directory in which you used git init for the first time. It is also where you can find the .git directory.

Simply do the following in didFinishWithLaunching::

if #available(iOS 10.0, *) {

    let center = UNUserNotificationCenter.current()

    center.delegate = self
    center.requestAuthorization(options: []) { _, _ in
        application.registerForRemoteNotifications()
    }
}

Remember about import statement:

import UserNotifications

In case you already have a "Configuration" with many migrations and want to keep this as is, you can always create a new "Configuration" class, give it another name, like

class MyNewContextConfiguration : DbMigrationsConfiguration<MyNewDbContext>
{
   ...
}

then just issue the command

Add-Migration -ConfigurationTypeName MyNewContextConfiguration InitialMigrationName

and EF will scaffold the migration without problems. Finally update your database, from now on, EF will complain if you don't tell him which configuration you want to update:

Update-Database -ConfigurationTypeName MyNewContextConfiguration 

Done.

You don't need to deal with Enable-Migrations as it will complain "Configuration" already exists, and renaming your existing Configuration class will bring issues to the migration history.

You can target different databases, or the same one, all configurations will share the __MigrationHistory table nicely.

Drop the spaces around the = sign:

#!/bin/bash 
STR="Hello World" 
echo $STR 

you can use pathlib

from pathlib import Path
Path(r"C:\folder1\folder2\filename.xml").parts[-2]

The output of the above was this:

'folder2'

Getting rid of Integrated Security=true worked for me.

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

You can write your For loop to individually store dataframes from a list:

allocation = list()

for(i in 1:length(allocation)){
    write.csv(data.frame(allocation[[i]]), file = paste0(path, names(allocation)[i], '.csv'))
}

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

The answer by Gruik worked for me in the below thread.

{Excerpt | Zend_Service_Twitter - Make API v1.1 ready}

with ZF 1.12.3 the workaround is to pass consumerKey and consumerSecret in oauthOptions option, not directrly in the options.

You don't need to use jQuery for this!

The native JavaScript implementation is Date.now().

Date.now() and $.now() return the same value:

Date.now(); // 1421715573651
$.now();    // 1421715573651

new Date(Date.now())   // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
new Date($.now());     // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)

..and if you want the time formatted in hh-mm-ss:

var now = new Date(Date.now());
var formatted = now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();
// 20:10:58

I've put together a utility method which employs all tips shown here plus some more:

        //1 local should never happen with the default settings but it can happen when settings get overriden   we want to forcibly return utc though
    }

Notice the use of '-' and 'T' (single-quoted). This is done as a matter of best practice since regional settings interfere with the interpretation of chars such as '-' causing it to be interpreted as '/' or '.' or whatever your regional settings denote as date-components-separator. I have also included a second utility method which show-cases how to parse most commonly seen date-string formats fed to rest-api backends from web clients. Enjoy.

h1 and h2 are native display: block elements.

Make them display: inline so they behave like normal text.

You should also reset the default padding and margin that the elements have.

The Comparable example given by several people here is wrong, since Enum already implements that. You can't even override it.

A better example is having an interface that defines, let's say, a data type. You can have an enum to implement the simple types, and have normal classes to implement complicated types:

interface DataType {
  // methods here
}

enum SimpleDataType implements DataType {
  INTEGER, STRING;

  // implement methods
}

class IdentifierDataType implements DataType {
  // implement interface and maybe add more specific methods
}

I took a similar approach as Sean3z but instead I have the connection closed everytime i make a query.

His way works if it's only executed on the entry point of your app, but let's say you have controllers that you want to do a var db = require('./db'). You can't because otherwise everytime you access that controller you will be creating a new connection.

To avoid that, i think it's safer, in my opinion, to open and close the connection everytime.

here is a snippet of my code.

mysq_query.js

// Dependencies
var mysql   = require('mysql'),
    config  = require("../config");

/*
 * @sqlConnection
 * Creates the connection, makes the query and close it to avoid concurrency conflicts.
 */
var sqlConnection = function sqlConnection(sql, values, next) {

    // It means that the values hasnt been passed
    if (arguments.length === 2) {
        next = values;
        values = null;
    }

    var connection = mysql.createConnection(config.db);
    connection.connect(function(err) {
        if (err !== null) {
            console.log("[MYSQL] Error connecting to mysql:" + err+'\n');
        }
    });

    connection.query(sql, values, function(err) {

        connection.end(); // close the connection

        if (err) {
            throw err;
        }

        // Execute the callback
        next.apply(this, arguments);
    });
}

module.exports = sqlConnection;

Than you can use it anywhere just doing like

var mysql_query = require('path/to/your/mysql_query');
mysql_query('SELECT * from your_table where ?', {id: '1'}, function(err, rows)   {
    console.log(rows);
});

UPDATED: config.json looks like

{
        "db": {
        "user"     : "USERNAME",
        "password" : "PASSWORD",
        "database" : "DATABASE_NAME",
        "socketPath": "/tmp/mysql.sock"
    }
}

Hope this helps.

I was getting similar problem for other reason (url pattern test-response not added in csrf token) I resolved it by allowing my URL pattern in following property in config/local.properties:

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$

modified to

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$,/[^/]+(/[^?])+(test-response)$

You can use as below,

Select X.a, X.b, Y.c from (
                Select X.a as a, sum (b) as sum_b from name_table X
                group by X.a)X
left join from name_table Y on Y.a = X.a

Example;

CREATE TABLE #products (
    product_name VARCHAR(MAX),
    code varchar(3),
    list_price [numeric](8, 2) NOT NULL
);

INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('Dinding', 'ADE', 2000)
INSERT INTO #products VALUES ('Kaca', 'AKB', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)

--SELECT * FROM #products 
SELECT distinct x.code, x.SUM_PRICE, product_name FROM (SELECT code, SUM(list_price) as SUM_PRICE From #products 
               group by code)x
left join #products y on y.code=x.code

DROP TABLE #products

Dietrich's answer is probably just the thing you need for what you describe, sending bytes, but a closer analogue to the code you've provided for example would be using the bytearray type.

>>> key = bytearray([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])
>>> bytes(key)
b'\x13\x00\x00\x00\x08\x00'
>>> 

Unless you are doing a DB to track historical times more than a century ago, using

Modified datetime DEFAULT ((0)) 

is perfectly safe and sound and allows more elegant queries than '1753-01-01' and more efficient queries than NULL.

However, since first Modified datetime is the time at which the record was inserted, you can use:

Modified datetime NOT NULL DEFAULT (GETUTCDATE())

which avoids the whole issue and makes your inserts easier and safer - as in you don't insert it at all and SQL does the housework :-)

With that in place you can still have elegant and fast queries by using 0 as a practical minimum since it's guranteed to always be lower than any insert-generated GETUTCDATE().

A simple function like below will help :

public string GetCurrentPageName() 
{ 
    string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath; 
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath); 
    string sRet = oInfo.Name; 
    return sRet; 
} 

Old question - but I recently needed this along with the row count... here is a query for both - sorted by row count desc:

SELECT t.owner, 
       t.table_name, 
       t.num_rows, 
       Count(*) 
FROM   all_tables t 
       LEFT JOIN all_tab_columns c 
              ON t.table_name = c.table_name 
WHERE  num_rows IS NOT NULL 
GROUP  BY t.owner, 
          t.table_name, 
          t.num_rows 
ORDER  BY t.num_rows DESC; 

I think this code gets the same and is easier to read.

SELECT <some columns> 
FROM mytable
<maybe some joins here>
WHERE date >= (SELECT date from mytable)
OR date <= (SELECT date from mytable);

The TreeSet is one of two sorted collections (the other being TreeMap). It uses a Red-Black tree structure (but you knew that), and guarantees that the elements will be in ascending order, according to natural order. Optionally, you can construct a TreeSet with a constructor that lets you give the collection your own rules for what the order should be (rather than relying on the ordering defined by the elements' class) by using a Comparable or Comparator

and A LinkedHashSet is an ordered version of HashSet that maintains a doubly-linked List across all elements. Use this class instead of HashSet when you care about the iteration order. When you iterate through a HashSet the order is unpredictable, while a LinkedHashSet lets you iterate through the elements in the order in which they were inserted

I finally fixed this using the Google's camera app. It gets the phone's orientation by using a sensor and then sets the EXIF tag appropriately. The JPEG which comes out of the camera is not oriented automatically.

Also, the camera preview works properly only in the landscape mode. If you need your activity layout to be oriented in portrait, you will have to do it manually using the value from the orientation sensor.

Asterisk (*) works with alias. Ex:

from pyspark.sql.functions import *

df1 = df1.alias('df1')
df2 = df2.alias('df2')

df1.join(df2, df1.id == df2.id).select('df1.*')

BEWARE !! of LAST_INSERT_ID() if trying to return this primary key value within PHP.

I know this thread is not tagged PHP, but for anybody who came across this answer looking to return a MySQL insert id from a PHP scripted insert using standard mysql_query calls - it wont work and is not obvious without capturing SQL errors.

The newer mysqli supports multiple queries - which LAST_INSERT_ID() actually is a second query from the original.

IMO a separate SELECT to identify the last primary key is safer than the optional mysql_insert_id() function returning the AUTO_INCREMENT ID generated from the previous INSERT operation.

if Number > 19 and Number < 99:

    word = firstWord + secondWord 
if Number <20 and Number > 0:
    word = num2words1[Number]
if Number > 99:

The output of EXPLAIN PLAN is a debug output from Oracle's query optimiser. The COST is the final output of the Cost-based optimiser (CBO), the purpose of which is to select which of the many different possible plans should be used to run the query. The CBO calculates a relative Cost for each plan, then picks the plan with the lowest cost.

(Note: in some cases the CBO does not have enough time to evaluate every possible plan; in these cases it just picks the plan with the lowest cost found so far)

In general, one of the biggest contributors to a slow query is the number of rows read to service the query (blocks, to be more precise), so the cost will be based in part on the number of rows the optimiser estimates will need to be read.

For example, lets say you have the following query:

SELECT emp_id FROM employees WHERE months_of_service = 6;

(The months_of_service column has a NOT NULL constraint on it and an ordinary index on it.)

There are two basic plans the optimiser might choose here:

• Plan 1: Read all the rows from the "employees" table, for each, check if the predicate is true (months_of_service=6).
• Plan 2: Read the index where months_of_service=6 (this results in a set of ROWIDs), then access the table based on the ROWIDs returned.

Let's imagine the "employees" table has 1,000,000 (1 million) rows. Let's further imagine that the values for months_of_service range from 1 to 12 and are fairly evenly distributed for some reason.

The cost of Plan 1, which involves a FULL SCAN, will be the cost of reading all the rows in the employees table, which is approximately equal to 1,000,000; but since Oracle will often be able to read the blocks using multi-block reads, the actual cost will be lower (depending on how your database is set up) - e.g. let's imagine the multi-block read count is 10 - the calculated cost of the full scan will be 1,000,000 / 10; Overal cost = 100,000.

The cost of Plan 2, which involves an INDEX RANGE SCAN and a table lookup by ROWID, will be the cost of scanning the index, plus the cost of accessing the table by ROWID. I won't go into how index range scans are costed but let's imagine the cost of the index range scan is 1 per row; we expect to find a match in 1 out of 12 cases, so the cost of the index scan is 1,000,000 / 12 = 83,333; plus the cost of accessing the table (assume 1 block read per access, we can't use multi-block reads here) = 83,333; Overall cost = 166,666.

As you can see, the cost of Plan 1 (full scan) is LESS than the cost of Plan 2 (index scan + access by rowid) - which means the CBO would choose the FULL scan.

If the assumptions made here by the optimiser are true, then in fact Plan 1 will be preferable and much more efficient than Plan 2 - which disproves the myth that FULL scans are "always bad".

The results would be quite different if the optimiser goal was FIRST_ROWS(n) instead of ALL_ROWS - in which case the optimiser would favour Plan 2 because it will often return the first few rows quicker, at the cost of being less efficient for the entire query.

raise causes an exception to be raised. Some other languages use the verb 'throw' instead.

It's intended to signal an error situation; it flags that the situation is exceptional to the normal flow.

Raised exceptions can be caught again by code 'upstream' (a surrounding block, or a function earlier on the stack) to handle it, using a try, except combination.

This error is definite mismatch between the data that is advertised in the HTTP Headers and the data transferred over the wire.

It could come from the following:

1. Server: If a server has a bug with certain modules that changes the content but don't update the content-length in the header or just doesn't work properly. It was the case for the Node HTTP Proxy at some point (see here)

2. Proxy: Any proxy between you and your server could be modifying the request and not update the content-length header.

As far as I know, I haven't see those problem in IIS but mostly with custom written code.

Let me know if that helps.

Most of the answers here try to offer alternative to how to write the HTML code to include more data because at least up to CSS3 you cannot select an element by partial inner text. But it can be done, you just need to add a bit of vanilla JavaScript, notice since female also contains male it will be selected:

      cells = document.querySelectorAll('td');_x000D_
     console.log(cells);_x000D_
      [].forEach.call(cells, function (el) {_x000D_
     if(el.innerText.indexOf("male") !== -1){_x000D_
     //el.click(); click or any other option_x000D_
     console.log(el)_x000D_
     }_x000D_
    });

 <table>_x000D_
      <tr>_x000D_
        <td>Peter</td>_x000D_
        <td>male</td>_x000D_
        <td>34</td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>Susanne</td>_x000D_
        <td>female</td>_x000D_
        <td>14</td>_x000D_
      </tr>_x000D_
    </table>

<table>
  <tr>
    <td data-content="Peter">Peter</td>
    <td data-content="male">male</td>
    <td data-content="34">34</td>
  </tr>
  <tr>
    <td data-conten="Susanne">Susanne</td>
    <td data-content="female">female</td>
    <td data-content="14">14</td>
  </tr>
</table>

For Xml you can use XmlConvert.ToString method.

If you are on SQL Server 2008 or later you can use the date datatype:

SELECT *
FROM [User] U
WHERE CAST(U.DateCreated as DATE) = '2014-02-07'

It should be noted that if date column is indexed then this will still utilise the index and is SARGable. This is a special case for dates and datetimes.

You can see that SQL Server actually turns this into a > and < clause:

I've just tried this on a large table, with a secondary index on the date column as per @kobik's comments and the index is still used, this is not the case for the examples that use BETWEEN or >= and <:

SELECT *
FROM [User] U
WHERE CAST(U.DateCreated as DATE) = '2016-07-05'

Or, in Underscore

_.random(min, max)

I'm using

buildTypes.each {
    it.buildConfigField 'String', 'GoogleMapsApiKey', "\"$System.env.GoogleMapsApiKey\""
}

Its based on Dennis's answer but grabs its from an environment variable.

Keep it super simple:

jQuery Event Listener Way:

$(window).on('wheel', function(){
  whichDirection(event);
});

Vanilla JavaScript Event Listener Way:

if(window.addEventListener){
  addEventListener('wheel', whichDirection, false);
} else if (window.attachEvent) {
  attachEvent('wheel', whichDirection, false);
}

Function Remains The Same:

function whichDirection(event){
  console.log(event + ' WheelEvent has all kinds of good stuff to work with');
  var scrollDirection = event.deltaY;
  if(scrollDirection === 1){
    console.log('meet me at the club, going down', scrollDirection);
  } else if(scrollDirection === -1) {
    console.log('Going up, on a tuesday', scrollDirection);
  }
}

I wrote a more indepth post on it here ???????

public static class GlobalVariables
{
    // readonly variable
    public static string Foo
    {
        get
        {
            return "foo";
        }
    }

    // read-write variable
    public static string Bar
    {
        get
        {
            return HttpContext.Current.Application["Bar"] as string;
        }
        set
        {
            HttpContext.Current.Application["Bar"] = value;
        }
    }
}

If you prefer a non-object-oriented approach, move plt.xticks(rotation=70) to right before the two avail_plot calls, eg

plt.xticks(rotation=70)
avail_plot(axs[0], dates, s1, 'testing', 'green')
avail_plot(axs[1], dates, s1, 'testing2', 'red')

This sets the rotation property before setting up the labels. Since you have two axes here, plt.xticks gets confused after you've made the two plots. At the point when plt.xticks doesn't do anything, plt.gca() does not give you the axes you want to modify, and so plt.xticks, which acts on the current axes, is not going to work.

For an object-oriented approach not using plt.xticks, you can use

plt.setp( axs[1].xaxis.get_majorticklabels(), rotation=70 )

after the two avail_plot calls. This sets the rotation on the correct axes specifically.

There is no need to use any plugin, you can do it like this:

var divPosition = $('#divId').offset();

then use this to scroll document to specific DOM:

$('html, body').animate({scrollTop: divPosition.top}, "slow");

Just for completeness: You can pass slice a vector of indices:

df %>% arrange(stopSequence) %>% group_by(id) %>% slice(c(1,n()))

which gives

  id stopId stopSequence
1  1      a            1
2  1      c            3
3  2      b            1
4  2      c            4
5  3      b            1
6  3      a            3

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

JSFiddle sample

Try this new source :

student.h

#include <iostream>

struct Student {
    std::string lastName;
    std::string firstName;
};

student.cpp

#include "student.h"

struct Student student;

If you just need swipe, you are better off size wise just using only the part you need. This should work on any touch device.

This is ~450 bytes' after gzip compression, minification, babel etc.

I wrote the below class based on the other answers, it uses percentage moved instead of pixels, and a event dispatcher pattern to hook/unhook things.

Use it like so:

Extending la_f0ka's comment, esp. if you also need the index position in your code, you should be able to do

s = 'ABCDEFG'
for pos in 0...s.length
    puts s[pos].chr
end

The .chr is important as Ruby < 1.9 returns the code of the character at that position instead of a substring of one character at that position.

try

<button onclick="window.location.href='b.php'">Click me</button>

Roman Shapovalov's code should work in Python 3.x as well as Python 2.6/2.7. Here it is again with the complete example:

import io
import numpy
x = "1 3\n 4.5 8"
numpy.genfromtxt(io.BytesIO(x.encode()))

Output:

array([[ 1. ,  3. ],
       [ 4.5,  8. ]])

Explanation for Python 3.x:

• numpy.genfromtxt takes a byte stream (a file-like object interpreted as bytes instead of Unicode).
• io.BytesIO takes a byte string and returns a byte stream. io.StringIO, on the other hand, would take a Unicode string and and return a Unicode stream.
• x gets assigned a string literal, which in Python 3.x is a Unicode string.
• encode() takes the Unicode string x and makes a byte string out of it, thus giving io.BytesIO a valid argument.

The only difference for Python 2.6/2.7 is that x is a byte string (assuming from __future__ import unicode_literals is not used), and then encode() takes the byte string x and still makes the same byte string out of it. So the result is the same.

Since this is one of SO's most popular questions regarding StringIO, here's some more explanation on the import statements and different Python versions.

Here are the classes which take a string and return a stream:

• io.BytesIO (Python 2.6, 2.7, and 3.x) - Takes a byte string. Returns a byte stream.
• io.StringIO (Python 2.6, 2.7, and 3.x) - Takes a Unicode string. Returns a Unicode stream.
• StringIO.StringIO (Python 2.x) - Takes a byte string or Unicode string. If byte string, returns a byte stream. If Unicode string, returns a Unicode stream.
• cStringIO.StringIO (Python 2.x) - Faster version of StringIO.StringIO, but can't take Unicode strings which contain non-ASCII characters.

Note that StringIO.StringIO is imported as from StringIO import StringIO, then used as StringIO(...). Either that, or you do import StringIO and then use StringIO.StringIO(...). The module name and class name just happen to be the same. It's similar to datetime that way.

What to use, depending on your supported Python versions:

• If you only support Python 3.x: Just use io.BytesIO or io.StringIO depending on what kind of data you're working with.

• If you support both Python 2.6/2.7 and 3.x, or are trying to transition your code from 2.6/2.7 to 3.x: The easiest option is still to use io.BytesIO or io.StringIO. Although StringIO.StringIO is flexible and thus seems preferred for 2.6/2.7, that flexibility could mask bugs that will manifest in 3.x. For example, I had some code which used StringIO.StringIO or io.StringIO depending on Python version, but I was actually passing a byte string, so when I got around to testing it in Python 3.x it failed and had to be fixed.

  Another advantage of using io.StringIO is the support for universal newlines. If you pass the keyword argument newline='' into io.StringIO, it will be able to split lines on any of \n, \r\n, or \r. I found that StringIO.StringIO would trip up on \r in particular.

  Note that if you import BytesIO or StringIO from six, you get StringIO.StringIO in Python 2.x and the appropriate class from io in Python 3.x. If you agree with my previous paragraphs' assessment, this is actually one case where you should avoid six and just import from io instead.

• If you support Python 2.5 or lower and 3.x: You'll need StringIO.StringIO for 2.5 or lower, so you might as well use six. But realize that it's generally very difficult to support both 2.5 and 3.x, so you should consider bumping your lowest supported version to 2.6 if at all possible.

There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back out to make modifications to it.

Step 1:

The First code snippet below should only be run if you are not already storing a serialized array in your localStorage session variable.
To ensure your localStorage is setup properly and storing an array, run the following code snippet first:

var a = [];
a.push(JSON.parse(localStorage.getItem('session')));
localStorage.setItem('session', JSON.stringify(a));

The above code should only be run once and only if you are not already storing an array in your localStorage session variable. If you are already doing this skip to step 2.

Step 2:

Modify your function like so:

function SaveDataToLocalStorage(data)
{
    var a = [];
    // Parse the serialized data back into an aray of objects
    a = JSON.parse(localStorage.getItem('session')) || [];
    // Push the new data (whether it be an object or anything else) onto the array
    a.push(data);
    // Alert the array value
    alert(a);  // Should be something like [Object array]
    // Re-serialize the array back into a string and store it in localStorage
    localStorage.setItem('session', JSON.stringify(a));
}

This should take care of the rest for you. When you parse it out, it will become an array of objects.

Hope this helps.

You have to hide the column at the grid view control rather than at the data source. Hiding it at the data source it will not render to the grid view at all, therefore you won't be able to access the value in the grid view. Doing it the way you're suggesting, you would have to access the column value through the data source as opposed to the grid view.

To hide the column on the grid view control, you can use code like this:

dataGridView1.Columns[0].Visible = false;

To access the column from the data source, you could try something like this:

object colValue = ((DataTable)dataGridView.DataSource).Rows[dataSetIndex]["ColumnName"];

Unlike other suggestions, this is short and doesn't use external libraries like numpy. (Not that using other libraries is bad...it's nice not need to, especially for such a simple problem.)

def line_intersection(line1, line2):
    xdiff = (line1[0][0] - line1[1][0], line2[0][0] - line2[1][0])
    ydiff = (line1[0][1] - line1[1][1], line2[0][1] - line2[1][1])

    def det(a, b):
        return a[0] * b[1] - a[1] * b[0]

    div = det(xdiff, ydiff)
    if div == 0:
       raise Exception('lines do not intersect')

    d = (det(*line1), det(*line2))
    x = det(d, xdiff) / div
    y = det(d, ydiff) / div
    return x, y

print line_intersection((A, B), (C, D))

And FYI, I would use tuples instead of lists for your points. E.g.

A = (X, Y)

EDIT: Initially there was a typo. That was fixed Sept 2014 thanks to @zidik.

This is simply the Python transliteration of the following formula, where the lines are (a1, a2) and (b1, b2) and the intersection is p. (If the denominator is zero, the lines have no unique intersection.)

Check if it's visible.

$("#singlechatpanel-1").is(':visible');

Check if it's hidden.

$("#singlechatpanel-1").is(':hidden');

Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.

You could change the encoding of your entire operating system. On Ubuntu you can do this with

sudo apt install locales 
sudo locale-gen en_US en_US.UTF-8    
sudo dpkg-reconfigure locales

if you want to get the name of the class simply call:-

id yourObject= [AnotherClass returningObject];

NSString *className=[yourObject className];

NSLog(@"Class name is : %@",className);

If you are a user of the free Visual Studio Express edition the right key is in

HKEY_CURRENT_USER\Software\Microsoft\VCExpress\9.0\Text Editor

{note the VCExpress instead of VisualStudio) but it works! :)

Zxing is an excellent library to perform Qr code scanning and generation. The following implementation uses Zxing library to scan the QR code image Don't forget to add following dependency in the build.gradle

implementation 'me.dm7.barcodescanner:zxing:1.9'

Code scanner activity:

    public class QrCodeScanner extends AppCompatActivity implements ZXingScannerView.ResultHandler {
        private ZXingScannerView mScannerView;

        @Override
        public void onCreate(Bundle state) {
            super.onCreate(state);
            // Programmatically initialize the scanner view
            mScannerView = new ZXingScannerView(this);
            // Set the scanner view as the content view
            setContentView(mScannerView);
        }

        @Override
        public void onResume() {
            super.onResume();
            // Register ourselves as a handler for scan results.
            mScannerView.setResultHandler(this);
            // Start camera on resume
            mScannerView.startCamera();
        }

        @Override
        public void onPause() {
            super.onPause();
            // Stop camera on pause
            mScannerView.stopCamera();
        }

        @Override
        public void handleResult(Result rawResult) {
            // Do something with the result here
            // Prints scan results
            Logger.verbose("result", rawResult.getText());
            // Prints the scan format (qrcode, pdf417 etc.)
            Logger.verbose("result", rawResult.getBarcodeFormat().toString());
            //If you would like to resume scanning, call this method below:
            //mScannerView.resumeCameraPreview(this);
            Intent intent = new Intent();
            intent.putExtra(AppConstants.KEY_QR_CODE, rawResult.getText());
            setResult(RESULT_OK, intent);
            finish();
        }
    }

Note that git checkout --ours|--theirs will overwrite the files entirely, by choosing either theirs or ours version, which might be or might not be what you want to do (if you have any non-conflicted changes coming from the other side, they will be lost).

If instead you want to perform a three-way merge on the file, and only resolve the conflicted hunks using --ours|--theirs, while keeping non-conflicted hunks from both sides in place, you may want to resort to git merge-file; see details in this answer.

I fixed in the below way with typescript

1. Define and initialize firest

pageNumbers: number[] = [];

2. than populate it

   for (let i = 1; i < 201; i++) {
       this.pageNumbers.push(i);
   }
   

ALTER SCHEMA TargetSchema 
    TRANSFER SourceSchema.TableName;

If you want to move all tables into a new schema, you can use the undocumented (and to be deprecated at some point, but unlikely!) sp_MSforeachtable stored procedure:

exec sp_MSforeachtable "ALTER SCHEMA TargetSchema TRANSFER ?"

Ref.: ALTER SCHEMA

SQL 2008: How do I change db schema to dbo

import re

htmlString = '</dd><dt> Fine, thank you.&#160;</dt><dd> Molt bé, gràcies. (<i>mohl behh, GRAH-syuhs</i>)'

SearchStr = '(\<\/dd\>\<dt\>)+ ([\w+\,\.\s]+)([\&\#\d\;]+)(\<\/dt\>\<dd\>)+ ([\w\,\s\w\s\w\?\!\.]+) (\(\<i\>)([\w\s\,\-]+)(\<\/i\>\))'

Result = re.search(SearchStr.decode('utf-8'), htmlString.decode('utf-8'), re.I | re.U)

print Result.groups()

Works that way. The expression contains non-latin characters, so it usually fails. You've got to decode into Unicode and use re.U (Unicode) flag.

I'm a beginner too and I faced that issue a couple of times myself.

If you want to use the call operator, the arguments can be an array stored in a variable:

$prog = 'c:\windows\system32\cmd.exe'
$myargs = '/c','dir','/x'
& $prog $myargs

The call operator works with ApplicationInfo objects too.

$prog = get-command cmd
$myargs = -split '/c dir /x'
& $prog $myargs

I can hardly name that an easy way (at least I can't remember the syntax), but it is possible to use time.strftime, which gives more control over formatting:

from time import strftime
from time import gmtime

strftime("%H:%M:%S", gmtime(666))
'00:11:06'

strftime("%H:%M:%S", gmtime(60*60*24))
'00:00:00'

gmtime is used to convert seconds to special tuple format that strftime() requires.

Note: Truncates after 23:59:59

Suppose you want to display some live feed content (say livefeed.txt) on you web page without any page refresh then the following simplified example is for you.

In the below html file, the live data gets updated on the div element of id "liveData"

index.html

<!DOCTYPE html>
<html>
<head>
    <title>Live Update</title>
    <meta charset="UTF-8">
    <script type="text/javascript" src="autoUpdate.js"></script>
</head>
<div id="liveData">
    <p>Loading Data...</p>
</div>
</body>
</html>

Below autoUpdate.js reads the live data using XMLHttpRequest object and updates the html div element on every 1 second. I have given comments on most part of the code for better understanding.

autoUpdate.js

window.addEventListener('load', function()
{
    var xhr = null;

    getXmlHttpRequestObject = function()
    {
        if(!xhr)
        {               
            // Create a new XMLHttpRequest object 
            xhr = new XMLHttpRequest();
        }
        return xhr;
    };

    updateLiveData = function()
    {
        var now = new Date();
        // Date string is appended as a query with live data 
        // for not to use the cached version 
        var url = 'livefeed.txt?' + now.getTime();
        xhr = getXmlHttpRequestObject();
        xhr.onreadystatechange = evenHandler;
        // asynchronous requests
        xhr.open("GET", url, true);
        // Send the request over the network
        xhr.send(null);
    };

    updateLiveData();

    function evenHandler()
    {
        // Check response is ready or not
        if(xhr.readyState == 4 && xhr.status == 200)
        {
            dataDiv = document.getElementById('liveData');
            // Set current data text
            dataDiv.innerHTML = xhr.responseText;
            // Update the live data every 1 sec
            setTimeout(updateLiveData(), 1000);
        }
    }
});

For testing purpose: Just write some thing in the livefeed.txt - You will get updated the same in index.html without any refresh.

livefeed.txt

Hello
World
blah..
blah..

Note: You need to run the above code on the web server (ex: http://localhost:1234/index.html) not as a client html file (ex: file:///C:/index.html).

<script>
    $(document).ready(function () {

            $.each($(".classBalence").find("span"), function () {
            if ($(this).text() >1) {
                $(this).css("color", "green")

            }
            if ($(this).text() < 1) {
                $(this).css("color", "red")
                $(this).css("font-weight", "bold")
            }
        });

    });
    </script>

NODE_ENV is an environmental variable that stands for node environment in express server.

It's how we set and detect which environment we are in.

It's very common using production and development.

Set:

export NODE_ENV=production

Get:

You can get it using app.get('env')

<input type="number" onchange="this.value=Math.max(Math.min(this.value, 100), -100);" />

or if you want to be able enter nothing

<input type="number" onchange="this.value=this.value ? Math.max(Math.min(this.value,100),-100) : null" />

If you have access to Underscore, you can use the following:

if (_.contains([1, 3, 12], foo)) {
  // ...
}

contains used to work in Lodash as well (prior to V4), now you have to use includes

if (_.includes([1, 3, 12], foo)) {
  handleYellowFruit();
}

HTML

<div id="myDiv" style="display:none;" class="answer_list" >WELCOME</div>
<input type="button" name="answer" onclick="ShowDiv()" />

JavaScript

function ShowDiv() {
    document.getElementById("myDiv").style.display = "";
}

Or if you wanted to use jQuery with a nice little animation:

<input id="myButton" type="button" name="answer" />

$('#myButton').click(function() {
  $('#myDiv').toggle('slow', function() {
    // Animation complete.
  });
});

Similar to Underscore library there is another library called as 'lodash' that has one method "orderBy" which takes in the parameter to determine in which order to sort it. You can use it like

_.orderBy('collection', 'propertyName', 'desc')

For some reason, it's not documented on the website docs.

var firstObjectsOfValues = (from d in dic select d.Value[0].ComponentValue("Dep"));

If table cols and values are variables then there are two ways:

With double quotes "" the complete query:

$query = "INSERT INTO $table_name (id, $col1, $col2)
                 VALUES (NULL, '$val1', '$val2')";

Or

 $query = "INSERT INTO ".$table_name." (id, ".$col1.", ".$col2.")
               VALUES (NULL, '".$val1."', '".$val2."')";

With single quotes '':

$query = 'INSERT INTO '.$table_name.' (id, '.$col1.', '.$col2.')
             VALUES (NULL, '.$val1.', '.$val2.')';

Use back ticks `` when a column/value name is similar to a MySQL reserved keyword.

Note: If you are denoting a column name with a table name then use back ticks like this:

`table_name`. `column_name` <-- Note: exclude . from back ticks.

An expression like this:

[a-zA-Z]*[0-9\+\*][a-zA-Z0-9\+\*]*

should work just fine (obviously insert any additional special characters you want to allow or use ^ operator to match anything except letters/numbers); no need to use complicated lookarounds. This approach makes sense if you only want to allow a certain subset of special characters that you know are "safe", and disallow all others.

If you want to include all special characters except certain ones which you know are "unsafe", then it makes sense to use something like:

\w[^\\]*[^a-zA-Z\\][^\\]*

In this case, you are explicitly disallowing backslashes in your password and allowing any combination with at least one non-alphabetic character otherwise.

The expression above will match any string containing letters and at least one number or +,*. As for the "length of 8" requirement, theres really no reason to check that using regex.

How about doing this in a much more elegant way with nodejs-config module.

This module is able to set configuration environment based on your computer's name. After that when you request a configuration you will get environment specific value.

For example lets assume your have two development machines named pc1 and pc2 and a production machine named pc3. When ever you request configuration values in your code in pc1 or pc2 you must get "development" environment configuration and in pc3 you must get "production" environment configuration. This can be achieved like this:

1. Create a base configuration file in the config directory, lets say "app.json" and add required configurations to it.
2. Now simply create folders within the config directory that matches your environment name, in this case "development" and "production".
3. Next, create the configuration files you wish to override and specify the options for each environment at the environment directories(Notice that you do not have to specify every option that is in the base configuration file, but only the options you wish to override. The environment configuration files will "cascade" over the base files.).

Now create new config instance with following syntax.

var config = require('nodejs-config')(
   __dirname,  // an absolute path to your applications 'config' directory
   {
      development: ["pc1", "pc2"],
      production: ["pc3"],

   }
);

Now you can get any configuration value without worrying about the environment like this:

config.get('app').configurationKey;

I would add a detail to the most voted answer:

If you're using gvim and want to copy to the clipboard, use

"+<command>

To copy all the content between brackets (or parens or curly brackets)

For example: "+yi} will copy to the clipboard all the content between the curly brackets your cursor is.

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%')

Just add this to your Action file in some div or td, so that it comes with incoming XML object

    <script type="text/javascript">
    $("#formname").resetForm();
    </script>

Where "formname" is the id of form you want to edit

I just want to point out that two of the solutions offered previously,

• Drag and drop from Windows Explorer
• Show All Files and then include in project.

do not do what the question asked for:

Include in project while preserving the directory structure.

At least not in my case (C++/CLI project Visual Studio 2013 on Windows 7).

In Visual Studio, once you are back in the normal view (not Show All Files), the files you added are all listed at the top level of the project.

Yes, on disk they still reside where they were, but in Solution Explorer they are loose.

I did not find a way around it except recreating the directory structure in Solution Explorer and then doing Add Existing Items at the right location.

You can use the <embed> tag with the source of the file in the src attribute. This uses the native browser PDF viewer.

<embed src="your_pdf_src" style="position:absolute; left: 0; top: 0;" width="100%" height="100%" type="application/pdf">

Live example:

<embed src="https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf" style="position:absolute; left: 0; top: 0;" width="100%" height="100%" type="application/pdf">

^{Loading the PDF inside a snippet won't work, since the frame into which the plugin is loading is sandboxed.}

Tested in Chrome and Firefox. See it in action.

I eventually shut-down and restarted Microsoft SQL Server Management Studio; and that fixed it for me. But at other times, just starting a new query window was enough.

I wonder what would you say about this array sorting code. It's quick for implementation and does the job ... haven't tested for large arrays yet. It works for one-dimensional arrays, for multidimensional additional values re-location matrix would need to be build (with one less dimension that the initial array).

       For AR1 = LBound(eArray, 1) To UBound(eArray, 1)
            eValue = eArray(AR1)
            For AR2 = LBound(eArray, 1) To UBound(eArray, 1)
                If eArray(AR2) < eValue Then
                    eArray(AR1) = eArray(AR2)
                    eArray(AR2) = eValue
                    eValue = eArray(AR1)
                End If
            Next AR2
        Next AR1

You can use Model.update() method.

With async/await:

try{
  const result = await Project.update(
    { title: "Updated Title" }, //what going to be updated
    { where: { id: 1 }} // where clause
  )  
} catch (error) {
  // error handling
}

With .then().catch():

Project.update(
    { title: "Updated Title" }, //what going to be updated
    { where: { id: 1 }} // where clause
)
.then(result => {
  // code with result
})
.catch(error => {
  // error handling
})

This is the only way that worked for me using Python 3.5.2 plus it's the easiest to implement w/ using the standard PyData suite

Shout out to https://stackoverflow.com/users/4502363/gadi-oron for the answer (I copied it completely) from How do I copy a string to the clipboard on Windows using Python?

import pandas as pd

I wrote a little wrapper for it that I put in my ipython profile <3

Here is the code for the short version of if-then-else statement:

( [ $a -eq 1 ] || [ $b -eq 2 ] ) && echo "ok" || echo "nok"

Pay attention to the following:

1. || and && operands inside if condition (i.e. between round parentheses) are logical operands (or/and)

2. || and && operands outside if condition mean then/else

Practically the statement says:

if (a=1 or b=2) then "ok" else "nok"

are there any cases where it doesn't work?

If the parent page was loaded from file://, then it probably does not work (it will try to get file://cdn.example.com/js_file.js, which of course you could provide locally as well).

Delegates are extremely useful when wanting to declare a block of code that you want to pass around. For example when using a generic retry mechanism.

Pseudo:

function Retry(Delegate func, int numberOfTimes)
    try
    {
       func.Invoke();
    }
    catch { if(numberOfTimes blabla) func.Invoke(); etc. etc. }

Or when you want to do late evaluation of code blocks, like a function where you have some Transform action, and want to have a BeforeTransform and an AfterTransform action that you can evaluate within your Transform function, without having to know whether the BeginTransform is filled, or what it has to transform.

And of course when creating event handlers. You don't want to evaluate the code now, but only when needed, so you register a delegate that can be invoked when the event occurs.

I believe you can just update your data structure, then:

[tableView beginUpdates];
[tableView deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES];
[tableView insertSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES];
[tableView endUpdates];

Also, the "withRowAnimation" is not exactly a boolean, but an animation style:

UITableViewRowAnimationFade,
UITableViewRowAnimationRight,
UITableViewRowAnimationLeft,
UITableViewRowAnimationTop,
UITableViewRowAnimationBottom,
UITableViewRowAnimationNone,
UITableViewRowAnimationMiddle

If you're using AVD manager add a hardware property Keyboard support and set it to false.

That should disable the shown keyboard, and show the virtual one.

My answer is based on the one provided by @x-yuri; but my scenario it's a little bit different. I wanted an image containing the script, not bind without needing to bind-mount it.

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

This syntax will work in XHTML and does not work in IE6, but this is a non-javascript way:

option[selected] { background: #f00; }

If you want to do this on-the-fly, then you would have to go with javascript, the way others have suggested....

Python installation folder > Lib > idlelib > idle.pyw

Double click on it and you're good to go.

No, you can use only some escape sequences - \n for example (maybe only this one).

You'll need to serialize to something: that is, pick binary, or xml (for default serializers) or write custom serialization code to serialize to some other text form.

Once you've picked that, your serialization will (normally) call a Stream that is writing to some kind of file.

So, with your code, if I were using XML Serialization:

var path = @"C:\Test\myserializationtest.xml";
using(FileStream fs = new FileStream(path, FileMode.Create))
{
    XmlSerializer xSer = new XmlSerializer(typeof(SomeClass));

    xSer.Serialize(fs, serializableObject);
}

Then, to deserialize:

using(FileStream fs = new FileStream(path, FileMode.Open)) //double check that...
{
    XmlSerializer _xSer = new XmlSerializer(typeof(SomeClass));

    var myObject = _xSer.Deserialize(fs);
}

NOTE: This code hasn't been compiled, let alone run- there may be some errors. Also, this assumes completely out-of-the-box serialization/deserialization. If you need custom behavior, you'll need to do additional work.

You are using jQuery, right? Separate JavaScript from HTML.

You can use trigger or triggerHandler.

var $myInput = $('#changeProgramatic').on('change', ChangeValue);

var anotherFunction = function() {
  $myInput.val('Another value');
  $myInput.trigger('change');
};

Click on "Tables" in "Connections" window, choose "Import data ...", follow the wizard and you will be asked for name for new table.

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);

For me worked only adding the config or ssh_config file that was on the dir ~/.ssh/config on my Linux system on the c:\Program Files\Git\etc\ssh\ directory on Windows.

In some git versions we need to edit the C:\Users\<username>\AppData\Local\Programs\Git\etc\ssh\ssh_config file.

After that, I was able to use all the alias and settings that I normally used on my Linux connecting or pushing via SSH on the Git Bash.

Loop over each object, appending a table row with the relevant data each iteration.

$(document).ready(function () {
    $.getJSON(url,
    function (json) {
        var tr;
        for (var i = 0; i < json.length; i++) {
            tr = $('<tr/>');
            tr.append("<td>" + json[i].User_Name + "</td>");
            tr.append("<td>" + json[i].score + "</td>");
            tr.append("<td>" + json[i].team + "</td>");
            $('table').append(tr);
        }
    });
});

In case this helps someone, I built a helper class for using visual format constraints. I'm using it in my current app.

AutolayoutHelper

It might be a bit tailored to my needs, but you might find it useful or you might want to modify it and create your own helper.

I have to thank Tim for his answer above, this answer about UIScrollView and also this tutorial.

Not sure if this is the most efficient answer, but it works for me:

import os
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = None # to avoid image size warning

imgdir = "/path/to/image/folder"
# if you want file of a specific extension (.png):
filelist = [f for f in glob.glob(imgdir + "**/*.png", recursive=True)]
savedir = "/path/to/image/folder/output"

start_pos = start_x, start_y = (0, 0)
cropped_image_size = w, h = (500, 500)

for file in filelist:
    img = Image.open(file)
    width, height = img.size

    frame_num = 1
    for col_i in range(0, width, w):
        for row_i in range(0, height, h):
            crop = img.crop((col_i, row_i, col_i + w, row_i + h))
            name = os.path.basename(file)
            name = os.path.splitext(name)[0]
            save_to= os.path.join(savedir, name+"_{:03}.png")
            crop.save(save_to.format(frame_num))
            frame_num += 1

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

Easy. Use .shape.

>>> nparray.shape
(5, 6) #Returns a tuple of array dimensions.

Note: I have verified this in the latest version of IE, and other browsers like Mozilla and Chrome and this works for me. Hope it works for others as well.

if (data == "" || data == undefined) {
    alert("Falied to open PDF.");
} else { //For IE using atob convert base64 encoded data to byte array
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        var byteCharacters = atob(data);
        var byteNumbers = new Array(byteCharacters.length);
        for (var i = 0; i < byteCharacters.length; i++) {
            byteNumbers[i] = byteCharacters.charCodeAt(i);
        }
        var byteArray = new Uint8Array(byteNumbers);
        var blob = new Blob([byteArray], {
            type: 'application/pdf'
        });
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    } else { // Directly use base 64 encoded data for rest browsers (not IE)
        var base64EncodedPDF = data;
        var dataURI = "data:application/pdf;base64," + base64EncodedPDF;
        window.open(dataURI, '_blank');

In my opinion, the solution proposed by user1965719 is really elegant. In my project, all objects going in to the containing div is dynamically created, so adding the extra hidden button is a breeze:

aspx code:

    <asp:Button runat="server" id="btnResponse1" Text="" 
    style="display: none; width:100%; height:100%"
    OnClick="btnResponses_Clicked" />

    <div class="circlebuttontext" id="calendarButtonText">Calendar</div>
</div>    

C# code behind:

protected void btnResponses_Clicked(object sender, EventArgs e)
{
    if(sender == btnResponse1)
    {
        //Your code behind logic for that button goes here
    }
}

There is also an option to use Handler -> postDelayed

 Handler().postDelayed({
                    //doSomethingHere()
                }, 1000)

The following shows an example of a shared class library shared.[h,cpp] and a main.cpp module using the library. It's a very simple example and the makefile could be made much better. But it works and may help you:

shared.h defines the class:

class myclass {
   int myx;

  public:

    myclass() { myx=0; }
    void setx(int newx);
    int  getx();
};

shared.cpp defines the getx/setx functions:

#include "shared.h"

void myclass::setx(int newx) { myx = newx; }
int  myclass::getx() { return myx; }

main.cpp uses the class,

#include <iostream>
#include "shared.h"

using namespace std;

int main(int argc, char *argv[])
{
  myclass m;

  cout << m.getx() << endl;
  m.setx(10);
  cout << m.getx() << endl;
}

and the makefile that generates libshared.so and links main with the shared library:

main: libshared.so main.o
    $(CXX) -o main  main.o -L. -lshared

libshared.so: shared.cpp
    $(CXX) -fPIC -c shared.cpp -o shared.o
    $(CXX) -shared  -Wl,-soname,libshared.so -o libshared.so shared.o

clean:
    $rm *.o *.so

To actual run 'main' and link with libshared.so you will probably need to specify the load path (or put it in /usr/local/lib or similar).

The following specifies the current directory as the search path for libraries and runs main (bash syntax):

export LD_LIBRARY_PATH=.
./main

To see that the program is linked with libshared.so you can try ldd:

LD_LIBRARY_PATH=. ldd main

Prints on my machine:

  ~/prj/test/shared$ LD_LIBRARY_PATH=. ldd main
    linux-gate.so.1 =>  (0xb7f88000)
    libshared.so => ./libshared.so (0xb7f85000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7e74000)
    libm.so.6 => /lib/libm.so.6 (0xb7e4e000)
    libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7e41000)
    libc.so.6 => /lib/libc.so.6 (0xb7cfa000)
    /lib/ld-linux.so.2 (0xb7f89000)

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);
  }

see https://jsfiddle.net/8xwocrp6/7/

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

MappedBy signals hibernate that the key for the relationship is on the other side.

This means that although you link 2 tables together, only 1 of those tables has a foreign key constraint to the other one. MappedBy allows you to still link from the table not containing the constraint to the other table.

I have used following code to escape the string value for json. You need to add your '"' to the output of the following code:

public static string EscapeStringValue(string value)
{
    const char BACK_SLASH = '\\';
    const char SLASH = '/';
    const char DBL_QUOTE = '"';

    var output = new StringBuilder(value.Length);
    foreach (char c in value)
    {
        switch (c)
        {
            case SLASH:
                output.AppendFormat("{0}{1}", BACK_SLASH, SLASH);
                break;

            case BACK_SLASH:
                output.AppendFormat("{0}{0}", BACK_SLASH);
                break;

            case DBL_QUOTE:
                output.AppendFormat("{0}{1}",BACK_SLASH,DBL_QUOTE);
                break;

            default:
                output.Append(c);
                break;
        }
    }

    return output.ToString();
}

Path Customization (tested in laravel 7) When a user is successfully authenticated, they will be redirected to the /home URI. You can customize the post-authentication redirect path using the HOME constant defined in your RouteServiceProvider:

public const HOME = '/home';

Since there is no php.ini file in your /public_html directory......create a new file as phpinfo.php in /public_html directory

-Type this code in phpinfo.php and save it:

<?php phpinfo(); ?>

-Then type yourdomain.com/phpinfo.php...you will see all the details of your configuration

-To edit that config, create another file as php.ini in /public_html directory and paste this code: memory_limit=512M
post_max_size=200M
upload_max_filesize=200M

-And then refresh yourdomain.com/phpinfo.php and see the changes,it will be done.
