This worked for me Visual C++ Redistributable Packages

UPDATE: Another writeup here: How to add publisher in Installshield 2018 (might be better).

I am not too well informed about this issue, but please see if this answer to another question tells you anything useful (and let us know so I can evolve a better answer here): How to pass the Windows Defender SmartScreen Protection? That question relates to BitRock - a non-MSI installer technology, but the overall issue seems to be the same.

Extract from one of the links pointed to in my answer above: "...a certificate just isn't enough anymore to gain trust... SmartScreen is reputation based, not unlike the way StackOverflow works... SmartScreen trusts installers that don't cause problems. Windows machines send telemetry back to Redmond about installed programs and how much trouble they cause. If you get enough thumbs-up then SmartScreen stops blocking your installer automatically. This takes time and lots of installs to get sufficient thumbs. There is no way to find out how far along you got."

Honestly this is all news to me at this point, so do get back to us with any information you dig up yourself.

The actual dialog text you have marked above definitely relates to the Zone.Identifier alternate data stream with a value of 3 that is added to any file that is downloaded from the Internet (see linked answer above for more details).

I was not able to mark this question as a duplicate of the previous one, since it doesn't have an accepted answer. Let's leave both question open for now? (one question is for MSI, one is for non-MSI).

When you write your main function, you typically see one of two definitions:

• int main(void)
• int main(int argc, char **argv)

The second form will allow you to access the command line arguments passed to the program, and the number of arguments specified (arguments are separated by spaces).

The arguments to main are:

• int argc - the number of arguments passed into your program when it was run. It is at least 1.
• char **argv - this is a pointer-to-char *. It can alternatively be this: char *argv[], which means 'array of char *'. This is an array of C-style-string pointers.

Basic Example

For example, you could do this to print out the arguments passed to your C program:

#include <stdio.h>

int main(int argc, char **argv)
{
    for (int i = 0; i < argc; ++i)
    {
        printf("argv[%d]: %s\n", i, argv[i]);
    }
}

I'm using GCC 4.5 to compile a file I called args.c. It'll compile and build a default a.out executable.

[birryree@lilun c_code]$ gcc -std=c99 args.c

Now run it...

[birryree@lilun c_code]$ ./a.out hello there
argv[0]: ./a.out
argv[1]: hello
argv[2]: there

So you can see that in argv, argv[0] is the name of the program you ran (this is not standards-defined behavior, but is common. Your arguments start at argv[1] and beyond.

So basically, if you wanted a single parameter, you could say...

./myprogram integral

A Simple Case for You

And you could check if argv[1] was integral, maybe like strcmp("integral", argv[1]) == 0.

So in your code...

#include <stdio.h>
#include <string.h>

int main(int argc, char **argv)
{
    if (argc < 2) // no arguments were passed
    {
        // do something
    }

    if (strcmp("integral", argv[1]) == 0)
    {
        runIntegral(...); //or something
    }
    else
    {
        // do something else.
    }
}

Better command line parsing

Of course, this was all very rudimentary, and as your program gets more complex, you'll likely want more advanced command line handling. For that, you could use a library like GNU getopt.

Do you want the JDK or the JRE? Anyways, I had this problem too, a few weeks ago. I followed the instructions here and it worked:

http://www.backtrack-linux.org/wiki/index.php/Java_Install

NOTE: Before installing Java make sure you kill Firefox.

root@bt:~# killall -9 /opt/firefox/firefox-bin

You can download java from the official website. (Download tar.gz version)

We first create the directory and place java there:

root@bt:~# mkdir /opt/java

root@bt:~# mv -f jre1.7.0_05/ /opt/java/

Final changes.

root@bt:~# update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_05/bin/java 1

root@bt:~# update-alternatives --set java /opt/java/jre1.7.0_05/bin/java

root@bt:~# export JAVA_HOME="/opt/java/jre1.7.0_05"

Adding the plugin to Firefox.

For Java 7 (32 bit)

root@bt:~# ln -sf $JAVA_HOME/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

For Java 8 (64 bit)

root@bt:~# ln -sf $JAVA_HOME/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

Testing the plugin.

root@bt:~# firefox http://java.com/en/download/testjava.jsp

1. From Package Explorer open the Filters... dialog:

2. Then uncheck .* resources option:

You can even write this:

    private string foo = "foo";

    private string bar
    {
        get => $"{foo}bar";
        set
        {
            foo = value;
        }
    }

First of all you need to install json-loader:

npm i json-loader --save-dev

Then, there are two ways how you can use it:

1. In order to avoid adding json-loader in each import you can add to webpack.config this line:

   loaders: [
     { test: /\.json$/, loader: 'json-loader' },
     // other loaders 
   ]
   

   Then import json files like this

   import suburbs from '../suburbs.json';
   

2. Use json-loader directly in your import, as in your example:

   import suburbs from 'json!../suburbs.json';
   

Note: In webpack 2.* instead of keyword loaders need to use rules.,

also webpack 2.* uses json-loader by default

*.json files are now supported without the json-loader. You may still use it. It's not a breaking change.

v2.1.0-beta.28

A tool to use here is awk:

cat file | awk 'BEGIN{ found=0} /TERMINATE/{found=1}  {if (found) print }'

How does this work:

1. We set the variable 'found' to zero, evaluating false
2. if a match for 'TERMINATE' is found with the regular expression, we set it to one.
3. If our 'found' variable evaluates to True, print :)

The other solutions might consume a lot of memory if you use them on very large files.

Java 8 added a new API for working with dates and times.

With Java 8 you can use the following lines of code:

// parse date from yyyy-mm-dd pattern
LocalDate januaryFirst = LocalDate.parse("2014-01-01");

// add one day
LocalDate januarySecond = januaryFirst.plusDays(1);

Use the git add command, followed by a list of space-separated filenames. Include paths if in other directories, e.g. directory-name/file-name.

git add file-1 file-2 file-3

This can be done by cloning to a new directory, then moving the .git directory into your existing directory.

If your existing directory is named "code".

git clone https://myrepo.com/git.git temp
mv temp/.git code/.git
rm -rf temp

This can also be done without doing a checkout during the clone command; more information can be found here.

Idea about helper functions is from one of the comments for DOM on php.net and idea about using unset is from kavoir.com. For me this solution finally worked:

function Myunset($node)
{
 unsetChildren($node);
 $parent = $node->parentNode;
 unset($node);
}

function unsetChildren($node)
{
 while (isset($node->firstChild))
 {
 unsetChildren($node->firstChild);
 unset($node->firstChild);
 }
}

using it: $xml is SimpleXmlElement

Myunset($xml->channel->item[$i]);

The result is stored in $xml, so don’t worry about assigning it to any variable.

Call SOAP webservice in c#

using (var client = new UpdatedOutlookServiceReferenceAPI.OutlookServiceSoapClient("OutlookServiceSoap"))
{
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
    var result = client.UploadAttachmentBase64(GUID, FinalFileName, fileURL);

    if (result == true)
    {
        resultFlag = true;
    }
    else
    {
        resultFlag = false;
    }
    LogWriter.LogWrite1("resultFlag : " + resultFlag);
}

As much as your available memory will allow. There's no size limit except for the heap.

Try this way:

message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
String address = "[email protected],[email protected]";
InternetAddress[] iAdressArray = InternetAddress.parse(address);
message.setRecipients(Message.RecipientType.CC, iAdressArray);

Set FormBorderStyle to 'FixedDialog'

toMap() in JSONObject works fine with nested objects and arrays already.

As the java.util.Map interface specifies to check the mappings and not the order, comparing the Maps is fine and also recursive.

json1 = new JSONObject("{...}");
json2 = new JSONObject("{...}");
json1.toMap().equals(json2.toMap());

It will work fine with any order and nested elements.

It will NOT however work with extra/ignored elements. If those are known you can remove them before calling equals on the maps.

If you are loading the image via AJAX you could use a callback to check if the image is loaded and do the hiding and src attribute assigning. Something like this:

$.ajax({ 
  url: [image source],
  success: function() {
  // Do the hiding here and the attribute setting
  }
});

FOR MAC USERS with CATALINA

First, install homebrew. Then, say

brew install [email protected]
brew link [email protected]

restart the console and run the laravel installer

You can escape % using %% for XML parser, but it is shown twice in device.

To show it once, try following format: \%%

For Example

<string name="zone_50">Fat Burning (50\%% to 60\%%)</string> 

is shown as Fat Burning (50% to 60%) in device

if you found out that the memory settings were not being used and in order to change the memory settings, I used the tomcat7w or tomcat8w in the \bin folder.Then the following should pop up:

Click the Java tab and add the arguments.restart tomcat

Is simple:

Example:https://jsfiddle.net/RainStudios/mw786v1w/

var element = document.getElementById('element');
//create box in bottom-left
var resizer = document.createElement('div');
resizer.style.width = '10px';
resizer.style.height = '10px';
resizer.style.background = 'red';
resizer.style.position = 'absolute';
resizer.style.right = 0;
resizer.style.bottom = 0;
resizer.style.cursor = 'se-resize';
//Append Child to Element
element.appendChild(resizer);
//box function onmousemove
resizer.addEventListener('mousedown', initResize, false);

//Window funtion mousemove & mouseup
function initResize(e) {
   window.addEventListener('mousemove', Resize, false);
   window.addEventListener('mouseup', stopResize, false);
}
//resize the element
function Resize(e) {
   element.style.width = (e.clientX - element.offsetLeft) + 'px';
   element.style.height = (e.clientY - element.offsetTop) + 'px';
}
//on mouseup remove windows functions mousemove & mouseup
function stopResize(e) {
    window.removeEventListener('mousemove', Resize, false);
    window.removeEventListener('mouseup', stopResize, false);
}

In addition to the existing answer it is possible to set a default option as follows:

echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:

This allows users to simply hit "Enter" if they want to enter the default.

Here's the final solution for the case in update section (with the help of Google Collections):

Collections2.transform (fooCollection, new Function<Foo, Bar>() {
    public Bar apply (Foo foo) {
        return new Bar (foo);
    }
}).toArray (new Bar[fooCollection.size()]);

But, the key approach here was mentioned in the doublep's answer (I forgot for toArray method).

This is same as above but does not handle errors:

s = open(filename, 'r').read()

Set the CommandText as well, and call Fill on the SqlAdapter to retrieve the results in a DataSet:

var con = new SqlConnection();
con.ConnectionString = "connection string";
var com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "sp_returnTable";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);

(Example is using parameterless constructors for clarity; can be shortened by using other constructors.)

For those who still might be facing issue adding jsx to test fixed it for me

test: /\.jsx?$/,

Suppose df is a pandas DataFrame then to get number of non-null values and data types of all column at once use:

df.info()

As has been noted, parsing the date and time is only useful if you know the format being used by the current user (eg. MM/dd/yy or dd-MM-yyyy just to name 2). This could be determined, but by the time you do all the stressing and parsing, you will still end up with some situation where there is an unexpected format used, and more tweaks will be be necessary.

You can also use some external program that will return a date slug in your preferred format, but that has disadvantages of needing to distribute the utility program with your script/batch.

there are also batch tricks using the CMOS clock in a pretty raw way, but that is tooo close to bare wires for most people, and also not always the preferred place to retrieve the date/time.

Below is a solution that avoids the above problems. Yes, it introduces some other issues, but for my purposes I found this to be the easiest, clearest, most portable solution for creating a datestamp in .bat files for modern Windows systems. This is just an example, but I think you will see how to modify for other date and/or time formats, etc.

reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM the following may be needed to be sure cache is clear before using the new setting
reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f

I was having having an issue with umake being an outdated version. What fixed it was:

sudo apt remove --purge ubuntu-make
sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
sudo apt update
sudo apt install ubuntu-make

We use Slick Grid in Stack Exchange Data Explorer (example containing 2000 rows).

I found it outperforms jqGrid and flexigrid. It has a very complete feature set and I could not recommend it enough.

Samples of its usage are here.

You can see source samples on how it is integrated to an ASP.NET MVC app here: https://code.google.com/p/stack-exchange-data-explorer/

If logical test is against a single column then you could use something like

USE AdventureWorks2012;  
GO  
SELECT   ProductNumber, Category =  
      CASE ProductLine  
         WHEN 'R' THEN 'Road'  
         WHEN 'M' THEN 'Mountain'  
         WHEN 'T' THEN 'Touring'  
         WHEN 'S' THEN 'Other sale items'  
         ELSE 'Not for sale'  
      END,  
   Name  
FROM Production.Product  
ORDER BY ProductNumber;  
GO

For those that need Powershell to return additional information like the Http StatusCode, here's an example. Included are the two most likely ways to pass in credentials.

Its a slightly modified version of this SO answer:
How to obtain numeric HTTP status codes in PowerShell

$req = [system.Net.WebRequest]::Create($url)
# method 1 $req.UseDefaultCredentials = $true
# method 2 $req.Credentials = New-Object System.Net.NetworkCredential($username, $pwd, $domain); 
try
{
    $res = $req.GetResponse()
}
catch [System.Net.WebException]
{
    $res = $_.Exception.Response
}

$int = [int]$res.StatusCode
$status = $res.StatusCode
return "$int $status"

I find the answer here.

It's because the server variable local_infile is set to FALSE|0. Refer from the document.

You can verify by executing:

SHOW VARIABLES LIKE 'local_infile';

If you have SUPER privilege you can enable it (without restarting server with a new configuration) by executing:

SET GLOBAL local_infile = 1;

Yes

document.location is the normal way.

However document.location is effectively the same as window.location, except for window.location is a bit more supported in older browsers so may be the prefferable choice.

Check out this thread on SO for more info:

What's the difference between window.location and document.location in JavaScript?

Example:

Let's say table A has two children B and C. Then we can use the following syntax to drop all tables.

DROP TABLE IF EXISTS B,C,A;

This can be placed in the beginning of the script instead of individually dropping each table.

It's pretty easy, just do it like this

$scope.props = [{order:"1"},{order:"5"},{order:"2"}]

ng-repeat="prop in props | orderBy:'order'"

Maybe some AJAX page content injection could be used as an alternative, though I still can't get around why your teacher would refuse to rid the website of frames.

Additionally, is there any specific reason you personally want to us HTML5?

But if not, I believe <iframe>s are still around.

Most of the previous answers are a bit(Very) complicated,

from google.colab import drive
drive.mount("/content/drive", force_remount=True)

I figured out this to be the easiest and fastest way to mount google drive into CO Lab, You can change the mount directory location to what ever you want by just changing the parameter for drive.mount. It will give you a link to accept the permissions with your account and then you have to copy paste the key generated and then drive will be mounted in the selected path.

force_remount is used only when you have to mount the drive irrespective of whether its loaded previously.You can neglect this when parameter if you don't want to force mount

The best thing to do is to install the Tampermonkey extension.

This will allow you to easily install Greasemonkey scripts, and to easily manage them. Also it makes it easier to install userscripts directly from sites like OpenUserJS, MonkeyGuts, etc.

Finally, it unlocks most all of the GM functionality that you don't get by installing a GM script directly with Chrome. That is, more of what GM on Firefox can do, is available with Tampermonkey.

But, if you really want to install a GM script directly, it's easy a right pain on Chrome these days...

Chrome After about August, 2014:

You can still drag a file to the extensions page and it will work... Until you restart Chrome. Then it will be permanently disabled. See Continuing to "protect" Chrome users from malicious extensions for more information. Again, Tampermonkey is the smart way to go. (Or switch browsers altogether to Opera or Firefox.)

Chrome 21+ :

Chrome is changing the way extensions are installed. Userscripts are pared-down extensions on Chrome but. Starting in Chrome 21, link-click behavior is disabled for userscripts. To install a user script, drag the **.user.js* file into the Extensions page (chrome://extensions in the address input).

Older Chrome versions:

Merely drag your **.user.js* files into any Chrome window. Or click on any Greasemonkey script-link.

You'll get an installation warning:

Click Continue.

You'll get a confirmation dialog:

Click Add.

Notes:

1. Scripts installed this way have limitations compared to a Greasemonkey (Firefox) script or a Tampermonkey script. See Cross-browser user-scripting, Chrome section.

Controlling the Script and name:

By default, Chrome installs scripts in the Extensions folder¹, full of cryptic names and version numbers. And, if you try to manually add a script under this folder tree, it will be wiped the next time Chrome restarts.

To control the directories and filenames to something more meaningful, you can:

1. Create a directory that's convenient to you, and not where Chrome normally looks for extensions. For example, Create: C:\MyChromeScripts\.

2. For each script create its own subdirectory. For example, HelloWorld.

3. In that subdirectory, create or copy the script file. For example, Save this question's code as: HelloWorld.user.js.

4. You must also create a manifest file in that subdirectory, it must be named: manifest.json.

   For our example, it should contain:

   {
       "manifest_version": 2,
       "content_scripts": [ {
           "exclude_globs":    [  ],
           "include_globs":    [ "*" ],
           "js":               [ "HelloWorld.user.js" ],
           "matches":          [   "https://stackoverflow.com/*",
                                   "https://stackoverflow.com/*"
                               ],
           "run_at": "document_end"
       } ],
       "converted_from_user_script": true,
       "description":  "My first sensibly named script!",
       "name":         "Hello World",
       "version":      "1"
   }
   

   The manifest.json file is automatically generated from the meta-block by Chrome, when an user script is installed. The values of @include and @exclude meta-rules are stored in include_globs and exclude_globs, @match (recommended) is stored in the matches list. "converted_from_user_script": true is required if you want to use any of the supported GM_* methods.

5. Now, in Chrome's Extension manager (URL = chrome://extensions/), Expand "Developer mode".

6. Click the Load unpacked extension... button.

7. For the folder, paste in the folder for your script, In this example it is: C:\MyChromeScripts\HelloWorld.

8. Your script is now installed, and operational!

9. If you make any changes to the script source, hit the Reload link for them to take effect:

   

¹ The folder defaults to:

Windows XP:
  Chrome  : %AppData%\..\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
  Chromium: %AppData%\..\Local Settings\Application Data\Chromium\User Data\Default\Extensions\

Windows Vista/7/8:
  Chrome  : %LocalAppData%\Google\Chrome\User Data\Default\Extensions\
  Chromium: %LocalAppData%\Chromium\User Data\Default\Extensions\

Linux:
  Chrome  : ~/.config/google-chrome/Default/Extensions/
  Chromium: ~/.config/chromium/Default/Extensions/

Mac OS X:
  Chrome  : ~/Library/Application Support/Google/Chrome/Default/Extensions/
  Chromium: ~/Library/Application Support/Chromium/Default/Extensions/

Although you can change it by running Chrome with the --user-data-dir= option.

Try this:

function explode(){
  alert("Boom!");
}
setTimeout(explode, 2000);

That's something controlled by your terminal, not by printf.

printf simply sends a \t to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.

This is the PHP ternary operator (also known as a conditional operator) - if first operand evaluates true, evaluate as second operand, else evaluate as third operand.

Think of it as an "if" statement you can use in expressions. Can be very useful in making concise assignments that depend on some condition, e.g.

$param = isset($_GET['param']) ? $_GET['param'] : 'default';

There's also a shorthand version of this (in PHP 5.3 onwards). You can leave out the middle operand. The operator will evaluate as the first operand if it true, and the third operand otherwise. For example:

$result = $x ?: 'default';

It is worth mentioning that the above code when using i.e. $_GET or $_POST variable will throw undefined index notice and to prevent that we need to use a longer version, with isset or a null coalescing operator which is introduced in PHP7:

$param = $_GET['param'] ?? 'default';

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

Get UltraMon. Quickly.

http://realtimesoft.com/ultramon/

It doesn't let you specify what monitor an app starts on, but it lets you move an app to the another monitor, and keep its aspect ratio intact, with one mouse click. It is a very handy utility.

Most programs will start where you last left them. So if you have two monitors at work, but only one at home, it's possible to start you laptop at home and not see the apps running on the other monitor (which now isn't there). UltrMon also lets you move those orphan apps back to the main screen quickly and easily.

Option 1 using an InputStreamResource

Resource implementation for a given InputStream.

Should only be used if no other specific Resource implementation is > applicable. In particular, prefer ByteArrayResource or any of the file-based Resource implementations where possible.

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    InputStreamResource resource = new InputStreamResource(new FileInputStream(file));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

Option2 as the documentation of the InputStreamResource suggests - using a ByteArrayResource:

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    Path path = Paths.get(file.getAbsolutePath());
    ByteArrayResource resource = new ByteArrayResource(Files.readAllBytes(path));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

I'd rather use more convenient itemSelect event. With this event you can use org.primefaces.event.SelectEvent objects in your listener.

<p:selectOneMenu ...>
    <p:ajax event="itemSelect" 
        update="messages"
        listener="#{beanMB.onItemSelectedListener}"/>
</p:selectOneMenu>

With such listener:

public void onItemSelectedListener(SelectEvent event){
    MyItem selectedItem = (MyItem) event.getObject();
    //do something with selected value
}

But if i take the piece of sql and run it from sql management studio, it will run without issue.

If you are at liberty to, change the service account to your own login, which would inherit your language/regional perferences.

The real crux of the issue is:

I use the following to convert -> date.Value.ToString("MM/dd/yyyy HH:mm:ss")

Please start using parameterized queries so that you won't encounter these issues in the future. It is also more robust, predictable and best practice.

I found a jfiddle that might help here: http://jsfiddle.net/jaredwilli/SfJ8c/

Ive refactored the code to make it simpler for this.

// In your controller
var w = angular.element($window);
$scope.$watch(
  function () {
    return $window.innerWidth;
  },
  function (value) {
    $scope.windowWidth = value;
  },
  true
);

w.bind('resize', function(){
  $scope.$apply();
});

You can then reference to windowWidth from the html

<span ng-bind="windowWidth"></span>

When working with graphical user interfaces, you need to remember that drawing on a pane is done in the Java AWT/Swing event queue. You can't just use the Graphics object outside the paint()/paintComponent()/etc. methods.

However, you can use a technique called "Frame buffering". Basically, you need to have a BufferedImage and draw directly on it (see it's createGraphics() method; that graphics context you can keep and reuse for multiple operations on a same BufferedImage instance, no need to recreate it all the time, only when creating a new instance). Then, in your JPanel's paintComponent(), you simply need to draw the BufferedImage instance unto the JPanel. Using this technique, you can perform zoom, translation and rotation operations quite easily through affine transformations.

just make a function :

public Spanned fromHtml(String str){
  return Build.VERSION.SDK_INT >= 24 ? Html.fromHtml(str, Html.FROM_HTML_MODE_LEGACY) : Html.fromHtml(str);
}

round(value,significantDigit) is the ordinary solution, however this does not operate as one would expect from a math perspective when round values ending in 5. If the 5 is in the digit just after the one you're rounded to, these values are only sometimes rounded up as expected (i.e. 8.005 rounding to two decimal digits gives 8.01). For certain values due to the quirks of floating point math, they are rounded down instead!

i.e.

>>> round(1.0005,3)
1.0
>>> round(2.0005,3)
2.001
>>> round(3.0005,3)
3.001
>>> round(4.0005,3)
4.0
>>> round(1.005,2)
1.0
>>> round(5.005,2)
5.0
>>> round(6.005,2)
6.0
>>> round(7.005,2)
7.0
>>> round(3.005,2)
3.0
>>> round(8.005,2)
8.01

Weird.

Assuming your intent is to do the traditional rounding for statistics in the sciences, this is a handy wrapper to get the round function working as expected needing to import extra stuff like Decimal.

>>> round(0.075,2)

0.07

>>> round(0.075+10**(-2*5),2)

0.08

Aha! So based on this we can make a function...

def roundTraditional(val,digits):
   return round(val+10**(-len(str(val))-1), digits)

Basically this adds a value guaranteed to be smaller than the least given digit of the string you're trying to use round on. By adding that small quantity it preserve's round's behavior in most cases, while now ensuring if the digit inferior to the one being rounded to is 5 it rounds up, and if it is 4 it rounds down.

The approach of using 10**(-len(val)-1) was deliberate, as it the largest small number you can add to force the shift, while also ensuring that the value you add never changes the rounding even if the decimal . is missing. I could use just 10**(-len(val)) with a condiditional if (val>1) to subtract 1 more... but it's simpler to just always subtract the 1 as that won't change much the applicable range of decimal numbers this workaround can properly handle. This approach will fail if your values reaches the limits of the type, this will fail, but for nearly the entire range of valid decimal values it should work.

You can also use the decimal library to accomplish this, but the wrapper I propose is simpler and may be preferred in some cases.

Edit: Thanks Blckknght for pointing out that the 5 fringe case occurs only for certain values. Also an earlier version of this answer wasn't explicit enough that the odd rounding behavior occurs only when the digit immediately inferior to the digit you're rounding to has a 5.

You use the id property to the get the id, then the substr method to remove the first part of it, then optionally parseInt to turn it into a number:

var id = theElement.id.substr(5);

or:

var id = parseInt(theElement.id.substr(5));

Here is the code I use when I want to preload images before appending them to the page.

It is also important to check if the image is already loaded from the cache (for IE).

    //create image to preload:
    var imgPreload = new Image();
    $(imgPreload).attr({
        src: photoUrl
    });

    //check if the image is already loaded (cached):
    if (imgPreload.complete || imgPreload.readyState === 4) {

        //image loaded:
        //your code here to insert image into page

    } else {
        //go fetch the image:
        $(imgPreload).load(function (response, status, xhr) {
            if (status == 'error') {

                //image could not be loaded:

            } else {

                //image loaded:
                //your code here to insert image into page

            }
        });
    }

This alternate approach with filtering for format counts all available grub kernel modules:

I have merged some solutions to make a complete util for picking an image from Gallery or Camera. These are the features of ImagePicker util gist (also in a Github lib):

• Merged intents for Gallery and Camera resquests.
• Resize selected big images (e.g.: 2500 x 1600)
• Rotate image if necesary

Screenshot:

Edit: Here is a fragment of code to get a merged Intent for Gallery and Camera apps together. You can see the full code at ImagePicker util gist (also in a Github lib):

public static Intent getPickImageIntent(Context context) {
    Intent chooserIntent = null;

    List<Intent> intentList = new ArrayList<>();

    Intent pickIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    takePhotoIntent.putExtra("return-data", true);
    takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(context)));
    intentList = addIntentsToList(context, intentList, pickIntent);
    intentList = addIntentsToList(context, intentList, takePhotoIntent);

    if (intentList.size() > 0) {
        chooserIntent = Intent.createChooser(intentList.remove(intentList.size() - 1),
                context.getString(R.string.pick_image_intent_text));
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new Parcelable[]{}));
    }

    return chooserIntent;
}

private static List<Intent> addIntentsToList(Context context, List<Intent> list, Intent intent) {
    List<ResolveInfo> resInfo = context.getPackageManager().queryIntentActivities(intent, 0);
    for (ResolveInfo resolveInfo : resInfo) {
        String packageName = resolveInfo.activityInfo.packageName;
        Intent targetedIntent = new Intent(intent);
        targetedIntent.setPackage(packageName);
        list.add(targetedIntent);
    }
    return list;
}

} else {
    br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));

The answer of George Bailey works fine. I would just add the following flags and use sudo if needed:

 sudo rm -rf bin/node bin/node-waf include/node lib/node lib/pkgconfig/nodejs.pc share/man/man1/node

From Dockerfile reference:

• The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag.

• The ENV instruction sets the environment variable <key> to the value <value>.
  The environment variables set using ENV will persist when a container is run from the resulting image.

So if you need build-time customization, ARG is your best choice.
If you need run-time customization (to run the same image with different settings), ENV is well-suited.

If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable

Given the number of combinations involved, using ENV to set those features at runtime is best here.

But you can combine both by:

• building an image with a specific ARG
• using that ARG as an ENV

That is, with a Dockerfile including:

ARG var
ENV var=${var}

You can then either build an image with a specific var value at build-time (docker build --build-arg var=xxx), or run a container with a specific runtime value (docker run -e var=yyy)

For Laravel 5.8, setting the csrf meta tag for your layout and setting the request header for csrf in ajax settings won't work if you are using ajax to submit a form that already includes a _token input field generated by the Laravel blade templating engine.

You must include the already generated csrf token from the form with your ajax request because the server would be expecting it and not the one in your meta tag.

For instance, this is how the _token input field generated by Blade looks like:

<form>
    <input name="_token" type="hidden" value="cf54ty6y7yuuyyygytfggfd56667DfrSH8i">
    <input name="my_data" type="text" value="">
    <!-- other input fields -->
</form>

You then submit your form with ajax like this:

<script> 
    $(document).ready(function() { 
        let token = $('form').find('input[name="_token"]').val();
        let myData = $('form').find('input[name="my_data"]').val();
        $('form').submit(function() { 
            $.ajax({ 
                type:'POST', 
                url:'/ajax', 
                data: {_token: token, my_data: myData}
                // headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}, // unnecessary 
                // other ajax settings
            }); 
            return false;
        }); 
    }); 
</script>

The csrf token in the meta header is only useful when you are submitting a form without a Blade generated _token input field.

As others have said, the minumum/maximum values the column can store and how much storage it takes in bytes is only defined by the type, not the length.

A lot of these answers are saying that the (11) part only affects the display width which isn't exactly true, but mostly.

A definition of int(2) with no zerofill specified will:

• still accept a value of 100
• still display a value of 100 when output (not 0 or 00)
• the display width will be the width of the largest value being output from the select query.

The only thing the (2) will do is if zerofill is also specified:

• a value of 1 will be shown 01.
• When displaying values, the column will always have a width of the maximum possible value the column could take which is 10 digits for an integer, instead of the miniumum width required to display the largest value that column needs to show for in that specific select query, which could be much smaller.
• The column can still take, and show a value exceeding the length, but these values will not be prefixed with 0s.

The best way to see all the nuances is to run:

CREATE TABLE `mytable` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `int1` int(10) NOT NULL,
    `int2` int(3) NOT NULL,
    `zf1` int(10) ZEROFILL NOT NULL,
    `zf2` int(3) ZEROFILL NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `mytable` 
(`int1`, `int2`, `zf1`, `zf2`) 
VALUES
(10000, 10000, 10000, 10000),
(100, 100, 100, 100);

select * from mytable;

which will output:

+----+-------+-------+------------+-------+
| id | int1  | int2  | zf1        | zf2   |
+----+-------+-------+------------+-------+
|  1 | 10000 | 10000 | 0000010000 | 10000 |
|  2 |   100 |   100 | 0000000100 |   100 |
+----+-------+-------+------------+-------+

Be aware of an issue with sparse unique indexes in MongoDB. I've hit it and it is extremely cumbersome to workaround.

The problem is this - you have a field, which is unique if present and you wish to find all the objects where the field is absent. The way sparse unique indexes are implemented in Mongo is that objects where that field is missing are not in the index at all - they cannot be retrieved by a query on that field - {$exists: false} just does not work.

The only workaround I have come up with is having a special null family of values, where an empty value is translated to a special prefix (like null:) concatenated to a uuid. This is a real headache, because one has to take care of transforming to/from the empty values when writing/quering/reading. A major nuisance.

I have never used server side javascript execution in MongoDB (it is not advised anyway) and their map/reduce has awful performance when there is just one Mongo node. Because of all these reasons I am now considering to check out CouchDB, maybe it fits more to my particular scenario.

BTW, if anyone knows the link to the respective Mongo issue describing the sparse unique index problem - please share.

To get the current time according to your timezone, you can use the following (in my case its '+5:30')

select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%Y-%m-%d')

It is important that you decorate the router link and link with square brackets as follows:

<a [routerLink]="['/service']"> <button class="btn btn-info"> link to other page </button></a>

Where "/service" in this case is the path url specified in the routing component.

Create SharedPreferences

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE); 
Editor editor = pref.edit();

Storing data as KEY/VALUE pair

editor.putBoolean("key_name1", true);           // Saving boolean - true/false
editor.putInt("key_name2", "int value");        // Saving integer
editor.putFloat("key_name3", "float value");    // Saving float
editor.putLong("key_name4", "long value");      // Saving long
editor.putString("key_name5", "string value");  // Saving string

// Save the changes in SharedPreferences
editor.apply(); // commit changes

Get SharedPreferences data

// If value for key not exist then return second param value - In this case null

boolean userFirstLogin= pref.getBoolean("key_name1", true);  // getting boolean
int pageNumber=pref.getInt("key_name2", 0);             // getting Integer
float amount=pref.getFloat("key_name3", null);          // getting Float
long distance=pref.getLong("key_name4", null);          // getting Long
String email=pref.getString("key_name5", null);         // getting String

Deleting Key value from SharedPreferences

editor.remove("key_name3"); // will delete key key_name3
editor.remove("key_name4"); // will delete key key_name4

// Save the changes in SharedPreferences
editor.apply(); // commit changes

Clear all data from SharedPreferences

 editor.clear();
 editor.apply(); // commit changes

GRANT USAGE ON SCHEMA schema_name TO user;

you can try this code:

DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)dataGridView1.CurrentRow.Cells[0];
                dataGridView1.BeginEdit(true);
                if (chk.Value == null || (int)chk.Value == 0)
                {
                    chk.Value = 1;
                }
                else
                {
                    chk.Value = 0;
                }
                dataGridView1.EndEdit();

Just to add to @Nathan Hughes's excellent answer:

The return statement can be used as a kind of control flow. By putting one (or more) return statements in the middle of a function, we can say: "stop executing this function. We've either got what we wanted or something's gone wrong!"

Here's an example:

>>> def make_3_characters_long(some_string):
...     if len(some_string) == 3:
...         return False
...     if str(some_string) != some_string:
...         return "Not a string!"
...     if len(some_string) < 3:
...         return ''.join(some_string,'x')[:,3]
...     return some_string[:,3]
... 
>>> threechars = make_3_characters_long('xyz')    
>>> if threechars:
...     print threechars
... else:
...     print "threechars is already 3 characters long!"
... 
threechars is already 3 characters long!

See the Code Style section of the Python Guide for more advice on this way of using return.

The command palette tells you the colours and their order when col = somefactor. It can also be used to set the colours as well.

palette()
[1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

In order to see that in your graph you could use a legend.

legend('topright', legend = levels(iris$Species), col = 1:3, cex = 0.8, pch = 1)

You'll notice that I only specified the new colours with 3 numbers. This will work like using a factor. I could have used the factor originally used to colour the points as well. This would make everything logically flow together... but I just wanted to show you can use a variety of things.

You could also be specific about the colours. Try ?rainbow for starters and go from there. You can specify your own or have R do it for you. As long as you use the same method for each you're OK.

This works in eclipse just to turn it red, don't know about other places.

System.err.println(" BLABLA ");

Things to add to your augmented question. I think you can often perfectly design more complicated business actions. But you have to give away the method/procedure style of thinking and think more in resources and verbs.

mail sendings

POST /customers/123/mails

payload:
{from: [email protected], subject: "foo", to: [email protected]}

The implementation of this resource + POST would then send out the mail. if necessary you could then offer something like /customer/123/outbox and then offer resource links to /customer/mails/{mailId}.

customer count

You could handle it like a search resource (including search metadata with paging and num-found info, which gives you the count of customers).

GET /customers

response payload:
{numFound: 1234, paging: {self:..., next:..., previous:...} customer: { ...} ....}

Try

String[] splited = str.split("\\s");

To change the labels for Pandas df.plot() use ax.legend([...]):

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
df.plot(kind='bar', ax=ax)
#ax = df.plot(kind='bar') # "same" as above
ax.legend(["AAA", "BBB"]);

Another approach is to do the same by plt.legend([...]):

import matplotlib.pyplot as plt
df.plot(kind='bar')
plt.legend(["AAA", "BBB"]);

                if(TextUtils.isEmpty(edit.getText())){ 

            // EditText was empty
             ErrorFields.add(edit);//add empty Edittext only in this ArayList
            for(int i = 0; i < ErrorFields.size(); i++)
            {
                EditText currentField = ErrorFields.get(i);
                currentField.setError("this field required");
                currentField.requestFocus();
            }
            }
            }

For expect, .equal will compare objects rather than their data, and in your case it is two different arrays.

Use .eql in order to deeply compare values. Check out this link.
Or you could use .deep.equal in order to simulate same as .eql.
Or in your case you might want to check .members.

For asserts you can use .deepEqual, link.

Main reason: Enums help you to write well-structured code where the semantic meaning of parameters is clear and strongly-typed at compile time - for all the reasons other answers have given.

Quid pro quo: in Java out of the box, an Enum's array of members is final. That's normally good as it helps value safety and testing, but in some situations it could be a drawback, for example if you are extending existing base code perhaps from a library. In contrast, if the same data is in a class with static fields you can easily add new instances of that class at runtime (you might also need to write code to add these to any Iterable you have for that class). But this behaviour of Enums can be changed: using reflection you can add new members at runtime or replace existing members, though this should probably only be done in specialised situations where there is no alternative: i.e. it's a hacky solution and may produce unexpected issues, see my answer on Can I add and remove elements of enumeration at runtime in Java.

Try this if you want to remove all section header completely

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

    return CGFloat.leastNormalMagnitude
}

import sys

print("\n".join(sys.argv))

sys.argv is a list that contains all the arguments passed to the script on the command line.

Basically,

import sys
print(sys.argv[1:])

The idea of programmatically setting constraints can be tiresome. This solution below will work for any layout whether constraint, linear, etc. Best way would be to set a placeholder i.e. a FrameLayout with proper constraints (or proper placing in other layout such as linear) at position where you would expect the programmatically created view to have.

All you need to do is inflate the view programmatically and it as a child to the FrameLayout by using addChild() method. Then during runtime your view would be inflated and placed in right position. Per Android recommendation, you should add only one childView to FrameLayout [link].

Here is what your code would look like, supposing you wish to create TextView programmatically at a particular position:

Step 1:

In your layout which would contain the view to be inflated, place a FrameLayout at the correct position and give it an id, say, "container".

Step 2 Create a layout with root element as the view you want to inflate during runtime, call the layout file as "textview.xml" :

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">

</TextView>

BTW, set the layout-params of your frameLayout to wrap_content always else the frame layout will become as big as the parent i.e. the activity i.e the phone screen.

android:layout_width="wrap_content"
android:layout_height="wrap_content"

If not set, because a child view of the frame, by default, goes to left-top of the frame layout, hence your view will simply fly to left top of the screen.

Step 3

In your onCreate method, do this :

FrameLayout frameLayout = findViewById(R.id.container);
                TextView textView = (TextView) View.inflate(this, R.layout.textview, null);
                frameLayout.addView(textView);

(Note that setting last parameter of findViewById to null and adding view by calling addView() on container view (frameLayout) is same as simply attaching the inflated view by passing true in 3rd parameter of findViewById(). For more, see this.)

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

It depends, if your function only consists of the switch statement, then I think that its fine. However, if you want to perform any other operations within that function, its probably not a great idea. You also may have to consider your requirements right now versus in the future. If you want to change your function from option one to option two, more refactoring will be needed.

However, given that within if/else statements it is best practice to do the following:

var foo = "bar";

if(foo == "bar") {
    return 0;
}
else {
    return 100;
}

Based on this, the argument could be made that option one is better practice.

In short, there's no clear answer, so as long as your code adheres to a consistent, readable, maintainable standard - that is to say don't mix and match options one and two throughout your application, that is the best practice you should be following.

I got the same error-message executed the
:PluginUpdate command from the vim editors command-line

"Please commit your changes or stash them before you merge"

1. just physically removed the folder contained the plugins form the

rm -rf ~/.vim/bundle/plugin-folder/

2. and reinstalled it form the vim commandline,
:PluginInstall!
because my ~/.vimrc contained the instructions to build the plugin to that destination:

this created the proper folder,
and got new package into that folder ~./.vim/bundle/reinstalled-plugins-folder
The "!" signs (due to the unsuccessful PluginUpdate command) were changed
to "+" signs, and after that worked the PluginUpdate command to.

you can use this project to play any you tube video , in your android app . Now for other video , or Video id ... you can do this https://gdata.youtube.com/feeds/api/users/eminemvevo/uploads/ where eminemvevo = channel .

after finding , video id , you can put that id in cueVideo("video_id")

src -> com -> examples -> youtubeapidemo -> PlayerViewDemoActivity

  @Override
  public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player , boolean wasRestored) {
    if (!wasRestored) {
      player.cueVideo("wKJ9KzGQq0w");
    }
  }

And specially for reading that video_id in a better way open this , and it as a xml[1st_file] file in your desktop after it create a new Xml file in your project or upload that[1st_file] saved file in your project , and right_click in it , and open it with xml_editor file , here you will find the video id of the particular video .

I think this is what you're looking for:

$('body').toggleClass("className");

perfectly works

The logic is wrong. Consider this:

x = ["a","b","c"]
x[0]     // "a"
x["0"]   // "a"
0 in x   // true
"0" in x // true
x.hasOwnProperty(0)   // true
x.hasOwnProperty("0") // true

There is no reason to loop to check for key (or indices for arrays) existence. Now, values are a different story...

Happy coding

You can call the get() method of AsyncTask (or the overloaded get(long, TimeUnit)). This method will block until the AsyncTask has completed its work, at which point it will return you the Result.

It would be wise to be doing other work between the creation/start of your async task and calling the get method, otherwise you aren't utilizing the async task very efficiently.

There is already a good solution to the problem you are having. Everyone has been forgetting the CSS property font-size: the last but not least solution. One can decrease the font size by 2 to 3 pixels. It may still be visible to the user and for somewhat you can decrease the width of the table. This worked for me. My table has 5 columns with 4 showing perfectly, but the fifth column went out of the viewport. To fix the problem, I decreased the font size and all five columns were fitted onto the screen.

table th td {
  font-size: 14px;
}

For your information, if your table has too many columns and you are not able to decrease, then make the font size small. It will get rid of the horizontal scroll. There are two advantages: your style for mobile web will remain the same (good without horizontal scroll) and when user sees small sizes, most users will zoom into the table to their comfort level.

cart.push({"element":{ id: id, quantity: quantity }});

It seems clear that $(TESTS) is empty so your 1.4.0 makefile is effectively

all: 

clean:
  rm -f  gtest.a gtest_main.a *.o

Indeed, all has nothing to do. and clean does exactly what it says rm -f gtest.a ...

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

Short version for easy use:

SELECT * 
FROM [TableName] t
WHERE t.[DateColumnName] >= DATEADD(month, -1, GETDATE())

DATEADD and GETDATE are available in SQL Server starting with 2008 version. MSDN documentation: GETDATE and DATEADD.

You cannot in pure CSS. Having an image covering the whole page behind all other components is probably your best bet (looks like that's the solution given above). Anyway, chances are it will look awful anyway. I would try either an image big enough to cover most screen resolutions (say up to 1600x1200, above it is scarcer), to limit the width of the page, or just to use an image that tile.

Here are seven steps to install spark on windows 10 and run it from python:

Step 1: download the spark 2.2.0 tar (tape Archive) gz file to any folder F from this link - https://spark.apache.org/downloads.html. Unzip it and copy the unzipped folder to the desired folder A. Rename the spark-2.2.0-bin-hadoop2.7 folder to spark.

Let path to the spark folder be C:\Users\Desktop\A\spark

Step 2: download the hardoop 2.7.3 tar gz file to the same folder F from this link - https://www.apache.org/dyn/closer.cgi/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gz. Unzip it and copy the unzipped folder to the same folder A. Rename the folder name from Hadoop-2.7.3.tar to hadoop. Let path to the hadoop folder be C:\Users\Desktop\A\hadoop

Step 3: Create a new notepad text file. Save this empty notepad file as winutils.exe (with Save as type: All files). Copy this O KB winutils.exe file to your bin folder in spark - C:\Users\Desktop\A\spark\bin

Step 4: Now, we have to add these folders to the System environment.

4a: Create a system variable (not user variable as user variable will inherit all the properties of the system variable) Variable name: SPARK_HOME Variable value: C:\Users\Desktop\A\spark

Find Path system variable and click edit. You will see multiple paths. Do not delete any of the paths. Add this variable value - ;C:\Users\Desktop\A\spark\bin

4b: Create a system variable

Variable name: HADOOP_HOME Variable value: C:\Users\Desktop\A\hadoop

Find Path system variable and click edit. Add this variable value - ;C:\Users\Desktop\A\hadoop\bin

4c: Create a system variable Variable name: JAVA_HOME Search Java in windows. Right click and click open file location. You will have to again right click on any one of the java files and click on open file location. You will be using the path of this folder. OR you can search for C:\Program Files\Java. My Java version installed on the system is jre1.8.0_131. Variable value: C:\Program Files\Java\jre1.8.0_131\bin

Find Path system variable and click edit. Add this variable value - ;C:\Program Files\Java\jre1.8.0_131\bin

Step 5: Open command prompt and go to your spark bin folder (type cd C:\Users\Desktop\A\spark\bin). Type spark-shell.

C:\Users\Desktop\A\spark\bin>spark-shell

It may take time and give some warnings. Finally, it will show welcome to spark version 2.2.0

Step 6: Type exit() or restart the command prompt and go the spark bin folder again. Type pyspark:

C:\Users\Desktop\A\spark\bin>pyspark

It will show some warnings and errors but ignore. It works.

Step 7: Your download is complete. If you want to directly run spark from python shell then: go to Scripts in your python folder and type

pip install findspark

in command prompt.

In python shell

import findspark
findspark.init()

import the necessary modules

from pyspark import SparkContext
from pyspark import SparkConf

If you would like to skip the steps for importing findspark and initializing it, then please follow the procedure given in importing pyspark in python shell

string replace() function perfectly solves this problem:

string.replace(s, old, new[, maxreplace])

Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

>>> u'longlongTESTstringTEST'.replace('TEST', '?', 1)
u'longlong?stringTEST'

Try this On window load submit your form.

window.onload = function(){
  document.forms['member_signup'].submit();
}

Just for funsies, if your dump is compressed you can do something like

gunzip -c filename.gz | psql dbname

As Jacob mentioned, the PostgreSQL docs describe all this quite well.

Say you have a superclass Fruit and the subclass Banana and you have a method addBananaToBasket()

The method will not accept grapes for example so you want to make sure that you're adding a banana to the basket.

So:

Fruit myFruit = new Banana();
((Banana)myFruit).addBananaToBasket(); ? This is called casting

You need to use javascript to show the name of the choosed file, as written in the documentation: https://getbootstrap.com/docs/4.5/components/forms/#file-browser

?vector

X <- vector(mode="character", length=10)

This will give you empty strings which get printed as two adjacent double quotes, but be aware that there are no double-quote characters in the values themselves. That's just a side-effect of how print.default displays the values. They can be indexed by location. The number of characters will not be restricted, so if you were expecting to get 10 character element you will be disappointed.

>  X[5] <- "character element in 5th position"

>  X
 [1] ""                                  ""

Arrays are different than ArrayLists, on which you could call add. You'll need an index first. Declare i before the for loop. Then you can use an array access expression to assign the element to the array.

num[i] = s;
i++;

In Java 8 for an Obj entity with field and getField() method you can use:

List<Obj> objs ...

Stream<Obj> notNullObjs =
  objs.stream().filter(obj -> obj.getValue() != null);

Double sum = notNullObjs.mapToDouble(Obj::getField).sum();

To get the data of a specific field,

$form->get('fieldName')->getData();

Or for all the form data

$form->getData();

New in C# 8.0 you can use the so-called "hat" (^) operator! This is useful for when you want to do something in one line!

var mystr = "Hello World!";
var lastword = mystr.Split(" ")[^1];
Console.WriteLine(lastword);
// World!

instead of the old way:

var mystr = "Hello World";
var split = mystr.Split(" ");
var lastword = split[split.Length - 1];
Console.WriteLine(lastword);
// World!

It doesn't save much space, but it looks much clearer (maybe I only think this because I came from python?). This is also much better than calling a method like .Last() or .Reverse() Read more at MSDN

Edit: You can add this functionality to your class like so:

public class MyClass
{
  public object this[Index indx]
  {
    get
    {
      // Do indexing here, this is just an example of the .IsFromEnd property
      if (indx.IsFromEnd)
      {
        Console.WriteLine("Negative Index!")
      }
      else
      {
        Console.WriteLine("Positive Index!")
      }
    }
  }
}

The Index.IsFromEnd will tell you if someone is using the 'hat' (^) operator

You can download files with the WebClient class:

using System.Net;

using (WebClient client = new WebClient ()) // WebClient class inherits IDisposable
{
    client.DownloadFile("http://yoursite.com/page.html", @"C:\localfile.html");

    // Or you can get the file content without saving it
    string htmlCode = client.DownloadString("http://yoursite.com/page.html");
}

Definition :- Big O notation is a notation which says how a algorithm performance will perform if the data input increases.

When we talk about algorithms there are 3 important pillars Input , Output and Processing of algorithm. Big O is symbolic notation which says if the data input is increased in what rate will the performance vary of the algorithm processing.

I would encourage you to see this youtube video which explains Big O Notation in depth with code examples.

So for example assume that a algorithm takes 5 records and the time required for processing the same is 27 seconds. Now if we increase the records to 10 the algorithm takes 105 seconds.

In simple words the time taken is square of the number of records. We can denote this by O(n ^ 2). This symbolic representation is termed as Big O notation.

Now please note the units can be anything in inputs it can be bytes , bits number of records , the performance can be measured in any unit like second , minutes , days and so on. So its not the exact unit but rather the relationship.

For example look at the below function "Function1" which takes a collection and does processing on the first record. Now for this function the performance will be same irrespective you put 1000 , 10000 or 100000 records. So we can denote it by O(1).

void Function1(List<string> data)
{
string str = data[0];
}

Now see the below function "Function2()". In this case the processing time will increase with number of records. We can denote this algorithm performance using O(n).

void Function2(List<string> data)
        {
            foreach(string str in data)
            {
                if (str == "shiv")
                {
                    return;
                }
            }
        }

When we see a Big O notation for any algorithm we can classify them in to three categories of performance :-

1. Log and constant category :- Any developer would love to see their algorithm performance in this category.
2. Linear :- Developer will not want to see algorithms in this category , until its the last option or the only option left.
3. Exponential :- This is where we do not want to see our algorithms and a rework is needed.

So by looking at Big O notation we categorize good and bad zones for algorithms.

I would recommend you to watch this 10 minutes video which discusses Big O with sample code

https://www.youtube.com/watch?v=k6kxtzICG_g

Late to the party, but what about

things.stream()
    .map(this::resolve)
    .filter(Optional::isPresent)
    .findFirst().get();

You can get rid of the last get() if you create a util method to convert optional to stream manually:

things.stream()
    .map(this::resolve)
    .flatMap(Util::optionalToStream)
    .findFirst();

If you return stream right away from your resolve function, you save one more line.

Here is a combination of the answer by @Mohsenasm and a comment from @Ghigo adopted to Swift

extension UIView {
    var globalFrame: CGRect? {
        let rootView = UIApplication.shared.keyWindow?.rootViewController?.view
        return self.superview?.convert(self.frame, to: rootView)
    }
}

First of all you have to understand the nature of

response.sendRedirect(newUrl);

It is giving the client (browser) 302 http code response with an URL. The browser then makes a separate GET request on that URL. And that request has no knowledge of headers in the first one.

So sendRedirect won't work if you need to pass a header from Servlet A to Servlet B.

If you want this code to work - use RequestDispatcher in Servlet A (instead of sendRedirect). Also, it is always better to use relative path.

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
    String userName=request.getParameter("userName");
    String newUrl = "ServletB";
    response.addHeader("REMOTE_USER", userName);
    RequestDispatcher view = request.getRequestDispatcher(newUrl);
    view.forward(request, response);
}

========================

public void doPost(HttpServletRequest request, HttpServletResponse response)
{
    String sss = response.getHeader("REMOTE_USER");
}

Using React Native 0.41 (in March 2017), targeting iOS, I just found it as easy as:

<Image source={require('./myimage.png')} />

The image file must exist in the same folder as the .js file requiring it.

I didn't have to change anything in the XCode project. It just worked. Maybe things have changed a lot in 2 years!

Note that if the filename has anything other than lower-case letters, or the path is anything more than "./", then for me, it started failing. Not sure what the restrictions are, but start simple and work forward.

Hope this helps someone, as many other answers here seem overly complex and full of (naughty) off-site links.

UPDATE: BTW - The official documentation for this is here: https://facebook.github.io/react-native/docs/images.html

in JDK 8, jdbc odbc bridge is no longer used and thus removed fro the JDK. to use Microsoft Access database in JAVA, you need 5 extra JAR libraries.

1- hsqldb.jar

2- jackcess 2.0.4.jar

3- commons-lang-2.6.jar

4- commons-logging-1.1.1.jar

5- ucanaccess-2.0.8.jar

add these libraries to your java project and start with following lines.

Connection conn=DriverManager.getConnection("jdbc:ucanaccess://<Path to your database i.e. MS Access DB>");
Statement s = conn.createStatement();

path could be like E:/Project/JAVA/DBApp

and then your query to be executed. Like

ResultSet rs = s.executeQuery("SELECT * FROM Course");
while(rs.next())
    System.out.println(rs.getString("Title") + " " + rs.getString("Code") + " " + rs.getString("Credits"));

certain imports to be used. try catch block must be used and some necessary things no to be forgotten.

Remember, no need of bridging drivers like jdbc odbc or any stuff.

As the comments mentioned, Go doesn't support ternary one liners. The shortest form I can think of is this:

var c int
if c = b; a > b {
    c = a
}

But please don't do that, it's not worth it and will only confuse people who read your code.

A Step Back

First and foremost, REST describes a URI as a universally unique ID. Far too many people get caught up on the structure of URIs and which URIs are more "restful" than others. This argument is as ludicrous as saying naming someone "Bob" is better than naming him "Joe" – both names get the job of "identifying a person" done. A URI is nothing more than a universally unique name.

So in REST's eyes arguing about whether ?id=["101404","7267261"] is more restful than ?id=101404,7267261 or \Product\101404,7267261 is somewhat futile.

Now, having said that, many times how URIs are constructed can usually serve as a good indicator for other issues in a RESTful service. There are a couple of red flags in your URIs and question in general.

Suggestions

1. Multiple URIs for the same resource and Content-Location

   We may want to accept both styles but does that flexibility actually cause more confusion and head aches (maintainability, documentation, etc.)?

   URIs identify resources. Each resource should have one canonical URI. This does not mean that you can't have two URIs point to the same resource but there are well defined ways to go about doing it. If you do decide to use both the JSON and list based formats (or any other format) you need to decide which of these formats is the main canonical URI. All responses to other URIs that point to the same "resource" should include the Content-Location header.

   Sticking with the name analogy, having multiple URIs is like having nicknames for people. It is perfectly acceptable and often times quite handy, however if I'm using a nickname I still probably want to know their full name – the "official" way to refer to that person. This way when someone mentions someone by their full name, "Nichloas Telsa", I know they are talking about the same person I refer to as "Nick".

2. "Search" in your URI

   A more complex case is when we want to offer more complex inputs. For example, if we want to allow multiple filters on search...

   A general rule of thumb of mine is, if your URI contains a verb, it may be an indication that something is off. URI's identify a resource, however they should not indicate what we're doing to that resource. That's the job of HTTP or in restful terms, our "uniform interface".

   To beat the name analogy dead, using a verb in a URI is like changing someone's name when you want to interact with them. If I'm interacting with Bob, Bob's name doesn't become "BobHi" when I want to say Hi to him. Similarly, when we want to "search" Products, our URI structure shouldn't change from "/Product/..." to "/Search/...".

Answering Your Initial Question

1. Regarding ["101404","7267261"] vs 101404,7267261: My suggestion here is to avoid the JSON syntax for simplicity's sake (i.e. don't require your users do URL encoding when you don't really have to). It will make your API a tad more usable. Better yet, as others have recommended, go with the standard application/x-www-form-urlencoded format as it will probably be most familiar to your end users (e.g. ?id[]=101404&id[]=7267261). It may not be "pretty", but Pretty URIs does not necessary mean Usable URIs. However, to reiterate my initial point though, ultimately when speaking about REST, it doesn't matter. Don't dwell too heavily on it.

2. Your complex search URI example can be solved in very much the same way as your product example. I would recommend going the application/x-www-form-urlencoded format again as it is already a standard that many are familiar with. Also, I would recommend merging the two.

Your URI...

/Search?term=pumas&filters={"productType":["Clothing","Bags"],"color":["Black","Red"]}    

Your URI after being URI encoded...

/Search?term=pumas&filters=%7B%22productType%22%3A%5B%22Clothing%22%2C%22Bags%22%5D%2C%22color%22%3A%5B%22Black%22%2C%22Red%22%5D%7D

Can be transformed to...

/Product?term=pumas&productType[]=Clothing&productType[]=Bags&color[]=Black&color[]=Red

Aside from avoiding the requirement of URL encoding and making things look a bit more standard, it now homogenizes the API a bit. The user knows that if they want to retrieve a Product or List of Products (both are considered a single "resource" in RESTful terms), they are interested in /Product/... URIs.

If you need to know when the iframe is ready to manipulate, use an interval. In this case I "ping" the content every 250 ms and if there's any content inside target iframe, stop the "ping" and do something.

var checkIframeLoadedInterval = setInterval( checkIframeLoaded, 250 );

function checkIframeLoaded() {
    var iframe_content = $('iframe').contents();

    if (iframe_content.length > 0) {
        clearInterval(checkIframeLoadedInterval);

        //Apply styles to the button
        setTimeout(function () {
            //Do something inside the iframe 
            iframe_content.find("body .whatever").css("background-color", "red");
        }, 100); //100 ms of grace time
    }
}

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

You might take a look at this:

https://github.com/michaelmoussa/ng-boolean-radio/

This guy wrote a custom directive to get around the issue that "true" and "false" are strings, not booleans.

transposing without any overhead (class not complete):

class Matrix{
   double *data; //suppose this will point to data
   double _get1(int i, int j){return data[i*M+j];} //used to access normally
   double _get2(int i, int j){return data[j*N+i];} //used when transposed

   public:
   int M, N; //dimensions
   double (*get_p)(int, int); //functor to access elements  
   Matrix(int _M,int _N):M(_M), N(_N){
     //allocate data
     get_p=&Matrix::_get1; // initialised with normal access 
     }

   double get(int i, int j){
     //there should be a way to directly use get_p to call. but i think even this
     //doesnt incur overhead because it is inline and the compiler should be intelligent
     //enough to remove the extra call
     return (this->*get_p)(i,j);
    }
   void transpose(){ //twice transpose gives the original
     if(get_p==&Matrix::get1) get_p=&Matrix::_get2;
     else get_p==&Matrix::_get1; 
     swap(M,N);
     }
}

can be used like this:

Matrix M(100,200);
double x=M.get(17,45);
M.transpose();
x=M.get(17,45); // = original M(45,17)

of course I didn't bother with the memory management here, which is crucial but different topic.

For me it was a permission problem.

enter:

mysqld --verbose --help | grep -A 1 "Default options"

[Warning] World-writable config file '/etc/mysql/my.cnf' is ignored.

So try to execute the following, and then restart the server

chmod 644 '/etc/mysql/my.cnf'

It will give mysql access to read and write to the file.

You can also get BLOB object directly from XMLHttpRequest. Setting responseType to blob makes the trick. Here is my code:

var xhr = new XMLHttpRequest();
xhr.open("GET", "http://localhost/image.jpg");
xhr.responseType = "blob";
xhr.onload = response;
xhr.send();

And the response function looks like this:

function response(e) {
   var urlCreator = window.URL || window.webkitURL;
   var imageUrl = urlCreator.createObjectURL(this.response);
   document.querySelector("#image").src = imageUrl;
}

We just have to make an empty image element in HTML:

<img id="image"/>

Very simple just Find:

<option value value=.*?>

and Click Replace

I can't give you graphics, but maybe I can give a clear explanation.

Suppose we have an information channel, such as a light that flashes once every day either red or green. How much information does it convey? The first guess might be one bit per day. But what if we add blue, so that the sender has three options? We would like to have a measure of information that can handle things other than powers of two, but still be additive (the way that multiplying the number of possible messages by two adds one bit). We could do this by taking log₂(number of possible messages), but it turns out there's a more general way.

Suppose we're back to red/green, but the red bulb has burned out (this is common knowledge) so that the lamp must always flash green. The channel is now useless, we know what the next flash will be so the flashes convey no information, no news. Now we repair the bulb but impose a rule that the red bulb may not flash twice in a row. When the lamp flashes red, we know what the next flash will be. If you try to send a bit stream by this channel, you'll find that you must encode it with more flashes than you have bits (50% more, in fact). And if you want to describe a sequence of flashes, you can do so with fewer bits. The same applies if each flash is independent (context-free), but green flashes are more common than red: the more skewed the probability the fewer bits you need to describe the sequence, and the less information it contains, all the way to the all-green, bulb-burnt-out limit.

It turns out there's a way to measure the amount of information in a signal, based on the the probabilities of the different symbols. If the probability of receiving symbol x_i is p_i, then consider the quantity

-log pi

The smaller p_i, the larger this value. If x_i becomes twice as unlikely, this value increases by a fixed amount (log(2)). This should remind you of adding one bit to a message.

If we don't know what the symbol will be (but we know the probabilities) then we can calculate the average of this value, how much we will get, by summing over the different possibilities:

I = -Σ pi log(pi)

This is the information content in one flash.

Red bulb burnt out: pred = 0, pgreen=1, I = -(0 + 0)  = 0
Red and green equiprobable: pred = 1/2, pgreen = 1/2, I = -(2 * 1/2 * log(1/2)) = log(2)
Three colors, equiprobable: pi=1/3, I = -(3 * 1/3 * log(1/3)) = log(3)
Green and red, green twice as likely: pred=1/3, pgreen=2/3, I = -(1/3 log(1/3) + 2/3 log(2/3)) = log(3) - 2/3 log(2)

This is the information content, or entropy, of the message. It is maximal when the different symbols are equiprobable. If you're a physicist you use the natural log, if you're a computer scientist you use log₂ and get bits.

use sp_helptrigger to find the triggerlist for the associated tables

Update: I also got this message when I was trying to build a query using @RawQuery and SupportSQLiteQuery inside the DAO.

@Transaction
public LiveData<List<MyEntity>> getList(MySettings mySettings) {
    //return getMyList(); -->this is ok

    return getMyList(new SimpleSQLiteQuery("select * from mytable")); --> this is an error

Solution: build the query inside the ViewModel and pass it to the DAO.

public MyViewModel(Application application) {
...
        list = Transformations.switchMap(searchParams, params -> {

            StringBuilder sql;
            sql = new StringBuilder("select  ... ");

            return appDatabase.rawDao().getList(new SimpleSQLiteQuery(sql.toString()));

        });
    }

Or...

You should not access the database directly on the main thread, for example:

 public void add(MyEntity item) {
     appDatabase.myDao().add(item); 
 }

You should use AsyncTask for update, add, and delete operations.

Example:

public class MyViewModel extends AndroidViewModel {

    private LiveData<List<MyEntity>> list;

    private AppDatabase appDatabase;

    public MyViewModel(Application application) {
        super(application);

        appDatabase = AppDatabase.getDatabase(this.getApplication());
        list = appDatabase.myDao().getItems();
    }

    public LiveData<List<MyEntity>> getItems() {
        return list;
    }

    public void delete(Obj item) {
        new deleteAsyncTask(appDatabase).execute(item);
    }

    private static class deleteAsyncTask extends AsyncTask<MyEntity, Void, Void> {

        private AppDatabase db;

        deleteAsyncTask(AppDatabase appDatabase) {
            db = appDatabase;
        }

        @Override
        protected Void doInBackground(final MyEntity... params) {
            db.myDao().delete((params[0]));
            return null;
        }
    }

    public void add(final MyEntity item) {
        new addAsyncTask(appDatabase).execute(item);
    }

    private static class addAsyncTask extends AsyncTask<MyEntity, Void, Void> {

        private AppDatabase db;

        addAsyncTask(AppDatabase appDatabase) {
            db = appDatabase;
        }

        @Override
        protected Void doInBackground(final MyEntity... params) {
            db.myDao().add((params[0]));
            return null;
        }

    }
}

If you use LiveData for select operations, you don't need AsyncTask.

COBOL allows that (I am sure some other languages do as well). Java inherited most of it's syntax from C which doesn't allow it.

The String being null is a very good chance, but when you see values in your table, yet a null is printed by the ResultSet, it might mean that the connection was closed before the value of ResultSet was used.

Class.forName("org.sqlite.JDBC");
con = DriverManager.getConnection("jdbc:sqlite:My_db.db");
String sql = ("select * from cust where cust_id='" + cus + "'");
pst = con.prepareStatement(sql);
rs = pst.executeQuery();
con.close();
System.out.println(rs.getString(1));

Would print null even if there are values.

Class.forName("org.sqlite.JDBC");
con = DriverManager.getConnection("jdbc:sqlite:My_db.db");
String sql = ("select * from cust where cust_id='" + cus + "'");
pst = con.prepareStatement(sql);
rs = pst.executeQuery();
System.out.println(rs.getString(1));
con.close();

Wouldn't print null if there are values in the table.

org.apache.commons.lang3.StringUtils.substring(s, -7) 

gives you the answer. It returns the input if it is shorter than 7, and null if s == null. It never throws an exception.

Try this way, allow you even filter by other key

data:

var my_data = [{"name":"Lenovo Thinkpad 41A4298","website":"google"},
{"name":"Lenovo Thinkpad 41A2222","website":"google"},
{"name":"Lenovo Thinkpad 41Awww33","website":"yahoo"},
{"name":"Lenovo Thinkpad 41A424448","website":"google"},
{"name":"Lenovo Thinkpad 41A429rr8","website":"ebay"},
{"name":"Lenovo Thinkpad 41A429ff8","website":"ebay"},
{"name":"Lenovo Thinkpad 41A429ss8","website":"rediff"},
{"name":"Lenovo Thinkpad 41A429sg8","website":"yahoo"}];

usage:

//We do that to ensure to get a correct JSON
var my_json = JSON.stringify(my_data)
//We can use {'name': 'Lenovo Thinkpad 41A429ff8'} as criteria too
var filtered_json = find_in_object(JSON.parse(my_json), {website: 'yahoo'});

filter function

function find_in_object(my_object, my_criteria){

  return my_object.filter(function(obj) {
    return Object.keys(my_criteria).every(function(c) {
      return obj[c] == my_criteria[c];
    });
  });

}

    List list1 = new ArrayList();
    list1.add("one");
    list1.add("three");
    list1.add("four");

    List list2 = new ArrayList();
    list2.add("one");
    list2.add("two");
    list2.add("three");
    list2.add("four");
    list2.add("five");


    list2.stream().filter( x -> !list1.contains(x) ).forEach(x -> System.out.println(x));

The output is:

Two problems will happen here:

1. Page load (content hidden)
2. Internal links like this will scroll to the top, and be hidden by the navbar:

<nav>...</nav>              <!-- 70 pixels tall -->
<a href="#hello">hello</a>  <!-- click to scroll down -->
<hr style="margin: 100px">
<h1 id="hello">World</h1>   <!-- Help!  I'm 70 pixels hidden! -->

Bootstrap 4 w/ internal page links

To fix 1), as Martijn Burger said above, the bootstrap v4 starter template css uses:

body {
  padding-top: 5rem;
}

To fix 2) check out this issue. This code mostly works (but not on 2nd click of same hash):

window.addEventListener("hashchange", function() { scrollBy(0, -70) })

This code animates A links with jQuery (not slim jQuery):

  // inline theme global code here
  $(document).ready(function() {
    var body = $('html,body'), NAVBAR_HEIGHT = 70;
    function smoothScrollingTo(target) {
      if($(target)) body.animate({scrollTop:$(target).offset().top - NAVBAR_HEIGHT}, 500);
    }
    $('a[href*=\\#]').on('click', function(event){
      event.preventDefault();
      smoothScrollingTo(this.hash);
    });
    $(document).ready(function(){
      smoothScrollingTo(location.hash);
    });
  })

How we Pause/stop YouTube iframe to when we use embed videos in modalpopup

 $('#close_one').click(function (e) {
         
         
         let link = document.querySelector('.divclass');// get iframe class 
         let link = document.querySelector('#divid');// get iframe id
         let video_src = link.getAttribute('src');

         $('.youtube-video').children('iframe').attr('src', ''); // set iframe parent div value null 
         $('.youtube-video').children('iframe').attr('src', video_src);// set iframe src again it works perfect

     });

This does cause "funky characters":

System.out.println( "Mr. Foo".trim().replace('.','\0'));

produces:

Mr[] Foo

in my Eclipse console, where the [] is shown as a square box. As others have posted, use String.replace().

Pull from the repository to a new directory, then rename the old one to old_crufty, and the new one to my_real_webserver_directory, and you're good to go.

If your intention is that every single file is in SVN, then this is a good way to test your theory. If your intention is that some files are not in SVN, then use Brian's copy/paste technique.

I found that there is height of div still showing, when it have text or not. So you can use this for best results.

<div style=" overflow:auto;max-height:300px; max-width:300px;"></div>

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

To click Ctrl+A, you can do it with Actions

  Actions action = new Actions(); 
  action.keyDown(Keys.CONTROL).sendKeys(String.valueOf('\u0061')).perform();

\u0061 represents the character 'a'

\u0041 represents the character 'A'

To press other characters refer the unicode character table - http://unicode.org/charts/PDF/U0000.pdf

With Python older than 2.7/3.1, that's pretty much how you do it.

For newer versions, see importlib.import_module for Python 2 and and Python 3.

You can use exec if you want to as well.

Or using __import__ you can import a list of modules by doing this:

>>> moduleNames = ['sys', 'os', 're', 'unittest'] 
>>> moduleNames
['sys', 'os', 're', 'unittest']
>>> modules = map(__import__, moduleNames)

Ripped straight from Dive Into Python.

In recent Oracle versions the COST represent the amount of time that the optimiser expects the query to take, expressed in units of the amount of time required for a single block read.

So if a single block read takes 2ms and the cost is expressed as "250", the query could be expected to take 500ms to complete.

The optimiser calculates the cost based on the estimated number of single block and multiblock reads, and the CPU consumption of the plan. the latter can be very useful in minimising the cost by performing certain operations before others to try and avoid high CPU cost operations.

This raises the question of how the optimiser knows how long operations take. recent Oracle versions allow the collections of "system statistics", which are definitely not to be confused with statistics on tables or indexes. The system statistics are measurements of the performance of the hardware, mostly importantly:

1. How long a single block read takes
2. How long a multiblock read takes
3. How large a multiblock read is (often different to the maximum possible due to table extents being smaller than the maximum, and other reasons).
4. CPU performance

These numbers can vary greatly according to the operating environment of the system, and different sets of statistics can be stored for "daytime OLTP" operations and "nighttime batch reporting" operations, and for "end of month reporting" if you wish.

Given these sets of statistics, a given query execution plan can be evaluated for cost in different operating environments, which might promote use of full table scans at some times or index scans at others.

The cost is not perfect, but the optimiser gets better at self-monitoring with every release, and can feedback the actual cost in comparison to the estimated cost in order to make better decisions for the future. this also makes it rather more difficult to predict.

Note that the cost is not necessarily wall clock time, as parallel query operations consume a total amount of time across multiple threads.

In older versions of Oracle the cost of CPU operations was ignored, and the relative costs of single and multiblock reads were effectively fixed according to init parameters.

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

Try this:

$WorkingDir = Convert-Path .

How about:

foreach(var s in listBox1.Items.ToArray())
{
    MessageBox.Show(s);
    //do stuff with (s);
    listBox1.Items.Remove(s);
}

The ToArray makes a copy of the list, so you don't need to worry about it changing the list while you are processing it.

For whatever reason, the svn solution does not work for me, and since I have no need of svn for anything else, it did not make sense to spend time trying to make it, so I looked for a simple solution using tools I already had. This script uses only curl and awk to download all files in a GitHub directory described as "/:user:repo/contents/:path".

The returned body of a call to the GitHub REST API "GET /repos/:user:repo/contents/:path" command returns an object that includes a "download_url" link for each file in a directory.

This command-line script calls that REST API using curl and sends the result through AWK, which filters out all but the "download_url" lines, erases quote marks and commas from the links, and then downloads the links using another call to curl.

curl -s https://api.github.com/repos/:user/:repo/contents/:path | awk \
     '/download_url/ { gsub("\"|,", "", $2); system("curl -O "$2"); }'

The ToolTip is a single WinForms control that handles displaying tool tips for multiple elements on a single form.

Say your button is called MyButton.

1. Add a ToolTip control (under Common Controls in the Windows Forms toolbox) to your form.
2. Give it a name - say MyToolTip
3. Set the "Tooltip on MyToolTip" property of MyButton (under Misc in the button property grid) to the text that should appear when you hover over it.

The tooltip will automatically appear when the cursor hovers over the button, but if you need to display it programmatically, call

MyToolTip.Show("Tooltip text goes here", MyButton);

in your code to show the tooltip, and

MyToolTip.Hide(MyButton);

to make it disappear again.

No curly braces required you can directly write

@if($user->status =='waiting')         
      <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{{ $user->travel_id }}" data-toggle="modal" data-target="#myModal">Approve/Reject<a></td>         
@else
      <td>{{ $user->status }}</td>        
@endif

You can append sendmail options to the end of the mail command by first adding --. -f is the command on sendmail to set the from address. So you can do this:

mail [email protected] -- -f [email protected]

Here's what I was able to use in a VBscript to detect Office 64bit Outlook:

Dim WshShell, blnOffice64, strOutlookPath

Checkout BigDecimal and BigInteger.

This is useful when you want to compare data that correspond to different units. In that case, you want to remove the units. To do that in a consistent way of all the data, you transform the data in a way that the variance is unitary and that the mean of the series is 0.

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy
    rNext.PasteSpecial xlPasteFormulasAndNumberFormats

    Application.CutCopyMode = False

End Sub

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

This happened to me when a stored procedure running in SSMS encountered an error during the loop, while the cursor was in use to iterate over records and before the it was closed. To fix it I added extra code in the CATCH block to close the cursor if it is still open (using CURSOR_STATUS as other answers here suggest).

If you imported an existing maven project and Maven dependencies are not showing in the build path in eclipse then right click on project--> Maven--> 'update Project' will resolve the issue.

First of all store $date=$_POST['your date field name'];

insert into **Your_Table Name** values('$date',**other fields**);

You must contain date in single cote (' ')

I hope it is helps.

To get the projects root directory within a Controller:

• Create a property for the hosting environment

  private readonly IHostingEnvironment _hostingEnvironment;
  

• Add Microsoft.AspNetCore.Hosting to your controller

  using Microsoft.AspNetCore.Hosting;
  

• Register the service in the constructor

  public HomeController(IHostingEnvironment hostingEnvironment) {
      _hostingEnvironment = hostingEnvironment;
  }
  

• Now, to get the projects root path

  string projectRootPath = _hostingEnvironment.ContentRootPath;
  

To get the "wwwroot" path, use

_hostingEnvironment.WebRootPath

Using the browser's Print... menu item, you can utilize a PDF Printer Driver, like PDFCreator. This way any JavaScript included in the page is processed by the browser when the page is rendered.

PDFCreator is a free tool to create PDF files from nearly any Windows application.

Basically you need to download the IEDriverServer.exe from Selenium HQ website without executing anything just remmeber the location where you want it and then put the code on Eclipse like this

System.setProperty("webdriver.ie.driver", "C:\\Users\\juan.torres\\Desktop\\QA stuff\\IEDriverServer_Win32_2.32.3\\IEDriverServer.exe");
WebDriver driver= new InternetExplorerDriver();

driver.navigate().to("http://www.youtube.com/");

for the path use double slash //

You are missing an include : #include <stdlib.h>, so GCC creates an implicit declaration of atof and atod, leading to garbage values.

And the format specifier for double is %f, not %d (that is for integers).

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

int main()
{
  char *test = "12.11";
  double temp = strtod(test,NULL);
  float ftemp = atof(test);
  printf("price: %f, %f",temp,ftemp);
  return 0;
}
/* Output */
price: 12.110000, 12.110000

I'm nowhere near as expert as others who have answered but I was having an issue with a procedure I was using to select a random row from a table (not overly relevant) but I needed to know the number of rows in my reference table to calculate the random index. Using the traditional Count(*) or Count(1) work but I was occasionally getting up to 2 seconds for my query to run. So instead (for my table named 'tbl_HighOrder') I am using:

Declare @max int

Select @max = Row_Count
From sys.dm_db_partition_stats
Where Object_Name(Object_Id) = 'tbl_HighOrder'

It works great and query times in Management Studio are zero.

There is an open source Javascript library that offers something related : mobile-bookmark-bubble

The Mobile Bookmark Bubble is a JavaScript library that adds a promo bubble to the bottom of your mobile web application, inviting users to bookmark the app to their device's home screen. The library uses HTML5 local storage to track whether the promo has been displayed already, to avoid constantly nagging users.

The current implementation of this library specifically targets Mobile Safari, the web browser used on iPhone and iPad devices.

Explanation:

This problem occurs because Chrome allows up to 6 open connections by default. So if you're streaming multiple media files simultaneously from 6 <video> or <audio> tags, the 7th connection (for example, an image) will just hang, until one of the sockets opens up. Usually, an open connection will close after 5 minutes of inactivity, and that's why you're seeing your .pngs finally loading at that point.

Solution 1:

You can avoid this by minimizing the number of media tags that keep an open connection. And if you need to have more than 6, make sure that you load them last, or that they don't have attributes like preload="auto".

Solution 2:

If you're trying to use multiple sound effects for a web game, you could use the Web Audio API. Or to simplify things, just use a library like SoundJS, which is a great tool for playing a large amount of sound effects / music tracks simultaneously.

Solution 3: Force-open Sockets (Not recommended)

If you must, you can force-open the sockets in your browser (In Chrome only):

1. Go to the address bar and type chrome://net-internals.
2. Select Sockets from the menu.
3. Click on the Flush socket pools button.

This solution is not recommended because you shouldn't expect your visitors to follow these instructions to be able to view your site.

If anyone is still experiencing this issue, I found that it related to a difference in Oracle Client versions.

I have posted my full experience and solution here: https://stackoverflow.com/a/43806765/923177

An "incomplete class" is one declared but not defined. E.g.

class Wielrenner;

as opposed to

class Wielrenner
{
    /* class members */
};

You need to #include "wielrenner.h" in dokter.ccp

If you are running as a user with administrator rights then environment variable SessionName will NOT be defined and you still don't have administrator rights when running a batch file.

You should use "net session" command and look for an error return code of "0" to verify administrator rights.

Example; - the first echo statement is the bell character net session >nul 2>&1 if not %errorlevel%==0 (echo echo You need to start over and right-click on this file, echo then select "Run as administrator" to be successfull. echo.&pause&exit)

Are you using express?

Check your path(note the "/" after /public/):

app.use(express.static(__dirname + "/public/"));

//note: you do not need the "/" before "css" because its already included above:

rel="stylesheet" href="css/style.css

Hope this helps

Sometimes you might add a state value from props in constructor or componentDidMount, you might need to call setState when the props changed but the component has already mounted so componentDidMount will not execute and neither will constructor; in this particular case, you can use componentDidUpdate since the props have changed, you can call setState in componentDidUpdate with new props.

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

Update for Java 8 and later

• isAfter()
• isBefore()
• isEqual()
• compareTo()

These methods exists in LocalDate, LocalTime, and LocalDateTime classes.

Those classes are built into Java 8 and later. Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP (see How to use…).

import * as Rx from 'rxjs';

const subject1 = new Rx.Subject();
subject1.next(1);
subject1.subscribe(x => console.log(x)); // will print nothing -> because we subscribed after the emission and it does not hold the value.

const subject2 = new Rx.Subject();
subject2.subscribe(x => console.log(x)); // print 1 -> because the emission happend after the subscription.
subject2.next(1);

const behavSubject1 = new Rx.BehaviorSubject(1);
behavSubject1.next(2);
behavSubject1.subscribe(x => console.log(x)); // print 2 -> because it holds the value.

const behavSubject2 = new Rx.BehaviorSubject(1);
behavSubject2.subscribe(x => console.log('val:', x)); // print 1 -> default value
behavSubject2.next(2) // just because of next emission will print 2 

All you need is to set values first to your RadioButton, for example:

RadioButton radioButton = (RadioButton)findViewById(R.id.radioButton);      
radioButton.setId(1);        //some int value

and then whenever this spacific radioButton will be chosen you can pull its value by the Id you gave it with

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup);                     
int whichIndex = radioGroup.getCheckedRadioButtonId(); //of course the radioButton
                                                       //should be inside the "radioGroup"
                                                       //in the XML

I implemented a pinch zoom for my TextView, using this tutorial. The resulting code is this:

private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;

and in onCreate():

    // Zoom handlers
    gestureDetector = new GestureDetector(new MyGestureDetector());
    gestureListener = new View.OnTouchListener() {

        // We can be in one of these 2 states
        static final int NONE = 0;
        static final int ZOOM = 1;
        int mode = NONE;

        static final int MIN_FONT_SIZE = 10;
        static final int MAX_FONT_SIZE = 50;

        float oldDist = 1f;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            TextView textView = (TextView) findViewById(R.id.text);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_POINTER_DOWN:
                    oldDist = spacing(event);
                    Log.d(TAG, "oldDist=" + oldDist);
                    if (oldDist > 10f) {
                       mode = ZOOM;
                       Log.d(TAG, "mode=ZOOM" );
                    }
                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    mode = NONE;
                    break;
                case MotionEvent.ACTION_MOVE:
                    if (mode == ZOOM) {
                        float newDist = spacing(event);
                        // If you want to tweak font scaling, this is the place to go.
                        if (newDist > 10f) {
                            float scale = newDist / oldDist;

                            if (scale > 1) {
                                scale = 1.1f;
                            } else if (scale < 1) {
                                scale = 0.95f;
                            }

                            float currentSize = textView.getTextSize() * scale;
                            if ((currentSize < MAX_FONT_SIZE && currentSize > MIN_FONT_SIZE)
                                    ||(currentSize >= MAX_FONT_SIZE && scale < 1)
                                    || (currentSize <= MIN_FONT_SIZE && scale > 1)) {
                                textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, currentSize);
                            }
                        }
                    }
                    break;
                }
            return false;
        }

Magic constants 1.1 and 0.95 were chosen empirically (using scale variable for this purpose made my TextView behave kind of weird).

I find marking the property as readonly cleaner than the above answers. I believe vb14 is required.

Private _Name As String

Public ReadOnly Property Name() As String
    Get
        Return _Name
    End Get
End Property

This can be condensed to

Public ReadOnly Property Name As String

During the installation you got a message Composer successfully installed to: ... this indicates where Composer was installed. But you might also search for the file composer.phar on your system.

Then simply:

As noted by others, after some years an 'out-of-core' pandas equivalent has emerged: dask. Though dask is not a drop-in replacement of pandas and all of its functionality it stands out for several reasons:

Dask is a flexible parallel computing library for analytic computing that is optimized for dynamic task scheduling for interactive computational workloads of “Big Data” collections like parallel arrays, dataframes, and lists that extend common interfaces like NumPy, Pandas, or Python iterators to larger-than-memory or distributed environments and scales from laptops to clusters.

Dask emphasizes the following virtues:

• Familiar: Provides parallelized NumPy array and Pandas DataFrame objects
• Flexible: Provides a task scheduling interface for more custom workloads and integration with other projects.
• Native: Enables distributed computing in Pure Python with access to the PyData stack.
• Fast: Operates with low overhead, low latency, and minimal serialization necessary for fast numerical algorithms
• Scales up: Runs resiliently on clusters with 1000s of cores Scales down: Trivial to set up and run on a laptop in a single process
• Responsive: Designed with interactive computing in mind it provides rapid feedback and diagnostics to aid humans

and to add a simple code sample:

import dask.dataframe as dd
df = dd.read_csv('2015-*-*.csv')
df.groupby(df.user_id).value.mean().compute()

replaces some pandas code like this:

import pandas as pd
df = pd.read_csv('2015-01-01.csv')
df.groupby(df.user_id).value.mean()

and, especially noteworthy, provides through the concurrent.futures interface a general infrastructure for the submission of custom tasks:

from dask.distributed import Client
client = Client('scheduler:port')

futures = []
for fn in filenames:
    future = client.submit(load, fn)
    futures.append(future)

summary = client.submit(summarize, futures)
summary.result()

Change the backend to automatic:

Tools > preferences > IPython console > Graphics > Graphics backend > Backend: Automatic

Then close and open Spyder.

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

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

By setting readonly attribute to either true or false is not going to work in most browsers, I have done it as below, when the mode of the page is "reload", I've not included "readonly" attribute.

@if(Model.Mode.Equals("edit")){
@Html.TextAreaFor(model => Model.Content.Data, new { id = "modEditor", @readonly = moduleEditModel.Content.ReadOnly, @style = "width:99%; height:360px;" })
}
@if (Model.Mode.Equals("reload")){
@Html.TextAreaFor(model => Model.Content.Data, new { id = "modEditor", @style = "width:99%; height:360px;" })}

Since Compose 1.18 (spec 3.5), you can just override the default network using your own custom name for all Compose YAML files you need. It is as simple as appending the following to them:

networks:
  default:
    name: my-app

The above assumes you have version set to 3.5 (or above if they don't deprecate it in 4+).

Other answers have pointed the same; this is a simplified summary.

As noted, numpy.random.seed(0) sets the random seed to 0, so the pseudo random numbers you get from random will start from the same point. This can be good for debuging in some cases. HOWEVER, after some reading, this seems to be the wrong way to go at it, if you have threads because it is not thread safe.

from differences-between-numpy-random-and-random-random-in-python:

For numpy.random.seed(), the main difficulty is that it is not thread-safe - that is, it's not safe to use if you have many different threads of execution, because it's not guaranteed to work if two different threads are executing the function at the same time. If you're not using threads, and if you can reasonably expect that you won't need to rewrite your program this way in the future, numpy.random.seed() should be fine for testing purposes. If there's any reason to suspect that you may need threads in the future, it's much safer in the long run to do as suggested, and to make a local instance of the numpy.random.Random class. As far as I can tell, random.random.seed() is thread-safe (or at least, I haven't found any evidence to the contrary).

example of how to go about this:

from numpy.random import RandomState
prng = RandomState()
print prng.permutation(10)
prng = RandomState()
print prng.permutation(10)
prng = RandomState(42)
print prng.permutation(10)
prng = RandomState(42)
print prng.permutation(10)

may give:

[3 0 4 6 8 2 1 9 7 5]

[1 6 9 0 2 7 8 3 5 4]

[8 1 5 0 7 2 9 4 3 6]

[8 1 5 0 7 2 9 4 3 6]

Lastly, note that there might be cases where initializing to 0 (as opposed to a seed that has not all bits 0) may result to non-uniform distributions for some few first iterations because of the way xor works, but this depends on the algorithm, and is beyond my current worries and the scope of this question.

At the time the compiler encounters the call to swapCase in main(), it does not know about the function swapCase, so it reports an error. You can either move the definition of swapCase above main, or declare swap case above main:

void swapCase(char* name);

Also, the 32 in swapCase causes the reader to pause and wonder. The comment helps! In this context, it would add clarity to write

if ('A' <= name[i] && name[i] <= 'Z')
    name[i] += 'a' - 'A';
else if ('a' <= name[i] && name[i] <= 'z')
    name[i] += 'A' - 'a';

The construction in my if-tests is a matter of personal style. Yours were just fine. The main thing is the way to modify name[i] -- using the difference in 'a' vs. 'A' makes it more obvious what is going on, and nobody has to wonder if the '32' is actually correct.

Good luck learning!

Include this setting in xampp my.ini configuration file:

For example summer :

If you do want to use null values with '=' or '<>' operators you may find the

answer from @egallardo hier

very useful.

Short example for '=': The expression

WHERE t.field = :param

you refactor like this

WHERE ((:param is null and t.field is null) or t.field = :param)

Now you can set the parameter param either to some non-null value or to null:

query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null);          // Works also

As of API 22, getResources().getDrawable() is deprecated (see also Android getResources().getDrawable() deprecated API 22). Here is a new way to set the image resource dynamically:

String resourceId = "@drawable/myResourceName"; // where myResourceName is the name of your resource file, minus the file extension
int imageResource = getResources().getIdentifier(resourceId, null, getPackageName());
Drawable drawable = ContextCompat.getDrawable(this, imageResource); // For API 21+, gets a drawable styled for theme of passed Context
imageview = (ImageView) findViewById(R.id.imageView);
imageview.setImageDrawable(drawable);

Use parents() instead of parent():

$("a").click(function(event) {
  event.preventDefault();
  $(this).parents('.li').remove();
});

Also, if you use Tortoise SVN you can do this:

1. In context menu select "TortoiseSVN", then "Properties"
2. In appeared window click "New", then "Advanced"
3. In appeared window opposite to "Property name" select or type "svn:ignore", opposite to "Property value" type desired file name or folder name or file mask (in my case it was "*/target"), click "Apply property recursively"
4. Ok. Ok.
5. Commit

We can use title() function with negative line value to bring down the title.

See this example:

plot(1, 1)
title("Title", line = -2)

Another option might be to merge with strategy ours to the commit before the range and then a 'normal' merge with the last commit of that range (or branch when it is the last one). So suppose only 2345 and 3456 commits of master to be merged into feature branch:

master:
1234
2345
3456
4567

in feature branch:

git merge -s ours 4567
git merge 2345
