UPDATE: I now have a complete turnkey, all-in-one answer, see https://stackoverflow.com/a/49019950/300224. Only took 3 years to figure out!

According to the Travis documentation: https://github.com/travis-ci/travis-ci there is a concoction of projects that collude to deliver the Travis CI web service we know and love. The following subset of projects appears to allow local make test functionality using the .travis.yml in your project:

travis-build

travis-build creates the build script for each job. It takes the configuration from the .travis.yml file and creates a bash script that is then run in the build environment by travis-worker.

travis-cookbooks

travis-cookbooks holds the Chef cookbooks that are used to provision the build environments.

travis-worker

travis-worker is responsible for running the build scripts in a clean environment. It streams the log output to travis-logs and pushes state updates (build starting/finishing) to travis-hub.

(The other subprojects are responsible for communicating with GitHub, their web interface, email, and their API.)

I had this problem of no .env files showing up in the project.

Turns out the IDE I was using (Netbeans, try not to judge) will show certain types of .hidden files but not all.

After racking my brains for a bit I checked the file system and found the .env + .env.example files / modified them with a text editor.

Leaving this answer for the rare situation someones using a dodgy IDE like myself.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

try this:

var span = document.getElementById("span");
span.style.fontSize = "25px";
span.innerHTML = "String";

Usually to use the library you need to install the dev version.

Try

sudo apt-get install libusb-1.0-0-dev

I wanted to change the column value in a specific row. Thanks to above answers and after some serching able to come up with below,

var dataTable = $("#yourtableid");
var rowNumber = 0;  
var columnNumber= 2;   
dataTable[0].rows[rowNumber].cells[columnNumber].innerHTML = 'New Content';

For Mac - Holding option key followed by ctrl V while selecting the text did the trick.

This solution is not good every time. But i have only two columns and I want second column to take all the remaining space. This worked for me

 <tr>
    <td class="text-nowrap">A</td>
    <td class="w-100">B</td>
 </tr>

More simple way with es6 style.

const indexOfAll = (arr, val) => arr.reduce((acc, el, i) => (el === val ? [...acc, i] : acc), []);


//Examples:
var cars = ["Nano", "Volvo", "BMW", "Nano", "VW", "Nano"];
indexOfAll(cars, "Nano"); //[0, 3, 5]
indexOfAll([1, 2, 3, 1, 2, 3], 1); // [0,3]
indexOfAll([1, 2, 3], 4); // []

Hold down Ctrl+Shift+P (or cmd on Mac), select "Change Language Mode" and there it is.

But I still can't find a way to make VS Code recognized files with specific extension as some certain language.

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

You are just missing the words "primary key" as far as I can see to meet your specified objective.

For your other columns it's best to explicitly define whether they should be NULL or NOT NULL though so you are not relying on the ANSI_NULL_DFLT_ON setting.

CREATE TABLE #tmp
(
ID INT IDENTITY(1, 1) primary key ,
AssignedTo NVARCHAR(100),
AltBusinessSeverity NVARCHAR(100),
DefectCount int
);

insert into #tmp 
select 'user','high',5 union all
select 'user','med',4


select * from #tmp

$(document).ready(function(){
$('#userForm').on('submit', function(e){
        e.preventDefault();
//I had an issue that the forms were submitted in geometrical progression after the next submit. 
// This solved the problem.
        e.stopImmediatePropagation();
    // show that something is loading
    $('#response').html("<b>Loading data...</b>");

    // Call ajax for pass data to other place
    $.ajax({
    type: 'POST',
    url: 'somephpfile.php',
    data: $(this).serialize() // getting filed value in serialize form
    })
    .done(function(data){ // if getting done then call.

    // show the response
    $('#response').html(data);

    })
    .fail(function() { // if fail then getting message

    // just in case posting your form failed
    alert( "Posting failed." );

    });

    // to prevent refreshing the whole page page
    return false;

    });

Not the right answer for people who really need to resize the image itself, but just to shrink the file size.

I had a problem with "directly from the camera" pictures, that my customers often uploaded in "uncompressed" JPEG.

Not so well known is, that the canvas supports (in most browsers 2017) to change the quality of JPEG

data=canvas.toDataURL('image/jpeg', .85) # [1..0] default 0.92

With this trick I could reduce 4k x 3k pics with >10Mb to 1 or 2Mb, sure it depends on your needs.

look here

I Just put my view background (color code) as ClipArt og Image background, and it looks like transparent or no background where both have the same color as background.

d = {} 

# import list of year,value pairs

for year,value in mylist:
    try:
        d[year].append(value)
    except KeyError:
        d[year] = [value]

The Python way - it is easier to receive forgiveness than ask permission!

For Kotlin and not only, when you write

@color/

you can choose whatever you want, fast and simply:

android:background="@color/md_blue_900"

BufferedReader bf= new BufferedReader(new FileReader("G://Sample.txt"));
        String line=bf.readLine();
        while(line!=null)
        {
            String[] words=line.split(" ");
            System.out.println("this line contains " +words.length+ " words");
            line=bf.readLine();
        }

1. Open the SQL Server Configuration Manager.... 2.Check wheather TCP and UDP are running or not.... 3.If not running , Please enable them and also check the SQL Server Browser is running or not.If not running turn it on.....

2. Next you have to check which ports TCP and UDP is using. You have to open those ports from your windows firewall.....

5.Click here to see the steps to open a specific port in windows firewall....

6. Now SQL Server is ready to access over LAN.......

7. If you wan to access it remotely (over internet) , you have to do another job that is 'Port Forwarding'. You have open the ports TCP and UDP is using in SQL Server on your router. Now the configuration of routers are different. If you give me the details of your router (i. e name of the company and version ) , I can show you the steps how to forward a specific port.

Here is a YouTube video that explains exactly what you're wanting to do: Save and load a Keras model

There are three different saving methods that Keras makes available. These are described in the video link above (with examples), as well as below.

First, the reason you're receiving the error is because you're calling load_model incorrectly.

To save and load the weights of the model, you would first use

model.save_weights('my_model_weights.h5')

to save the weights, as you've displayed. To load the weights, you would first need to build your model, and then call load_weights on the model, as in

model.load_weights('my_model_weights.h5')

Another saving technique is model.save(filepath). This save function saves:

• The architecture of the model, allowing to re-create the model.
• The weights of the model.
• The training configuration (loss, optimizer).
• The state of the optimizer, allowing to resume training exactly where you left off.

To load this saved model, you would use the following:

from keras.models import load_model
new_model = load_model(filepath)'

Lastly, model.to_json(), saves only the architecture of the model. To load the architecture, you would use

from keras.models import model_from_json
model = model_from_json(json_string)

Aus_lacy's post gave me the idea of trying related methods, of which join does work:

In [196]:

hl.name = 'hl'
Out[196]:
'hl'
In [199]:

df.join(hl).head(4)
Out[199]:

2014-01-01 17:01:00 1.376005    1.375775    NaN NaN NaN
2014-01-01 17:02:00 1.375795    1.375445    NaN 1.375445    1.375445
2014-01-01 17:03:00 1.375625    1.375515    NaN NaN NaN

Some insight into why concat works on the example but not this data would be nice though!

Note: You may also want to run

git clean -fd

as

git reset --hard

will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under git tracking. WARNING - BE CAREFUL WITH THIS! It is helpful to run a dry-run with git-clean first, to see what it will delete.

This is also especially useful when you get the error message

~"performing this command will cause an un-tracked file to be overwritten"

Which can occur when doing several things, one being updating a working copy when you and your friend have both added a new file of the same name, but he's committed it into source control first, and you don't care about deleting your untracked copy.

In this situation, doing a dry run will also help show you a list of files that would be overwritten.

You can add the --packages parameter with the appropriate jar: to your submission:

bin/spark-submit --packages com.amazonaws:aws-java-sdk-pom:1.10.34,org.apache.hadoop:hadoop-aws:2.6.0 code.py

There are necessary steps that are missing in the above answers to work for all levels of devs:

1. compile your class library project
2. the dll file will be available in the bin folder
3. in another project, right click ProjectName and select "Add" => "Existing Item"
4. Browser to the bin folder of the class library project and select the dll file (3 & 4 steps are important if you plan to ship your app to other machines)
5. as others mentioned, add reference to the dll file you "just" added to your project
6. as @Adam mentioned, just call the library name from anywhere in your program, you do not need a using statement

If you are running iOS 13 or above use this code in your SceneDelegate:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    
    guard let notificationResponse = connectionOptions.notificationResponse else { return }
    
    let pushTitle = notificationResponse.notification.request.content.title
    let pushSubtitle = notificationResponse.notification.request.content.subtitle
    let pushBody = notificationResponse.notification.request.content.body
    
    // do your staff here
}

Worst case will arise when both n and m are consecutive Fibonacci numbers.

gcd(Fn,Fn-1)=gcd(Fn-1,Fn-2)=?=gcd(F1,F0)=1 and nth Fibonacci number is 1.618^n, where 1.618 is the Golden ratio.

So, to find gcd(n,m), number of recursive calls will be T(logn).

As WhirlWind has pointed out, the recommendations to use atoi aren't really very good. atoi has no way to indicate an error, so you get the same return from atoi("0"); as you do from atoi("abc");. The first is clearly meaningful, but the second is a clear error.

He also recommended strtol, which is perfectly fine, if a little bit clumsy. Another possibility would be to use sscanf, something like:

if (1==sscanf(argv[1], "%d", &temp))
    // successful conversion
else
    // couldn't convert input

note that strtol does give slightly more detailed results though -- in particular, if you got an argument like 123abc, the sscanf call would simply say it had converted a number (123), whereas strtol would not only tel you it had converted the number, but also a pointer to the a (i.e., the beginning of the part it could not convert to a number).

Since you're using C++, you could also consider using boost::lexical_cast. This is almost as simple to use as atoi, but also provides (roughly) the same level of detail in reporting errors as strtol. The biggest expense is that it can throw exceptions, so to use it your code has to be exception-safe. If you're writing C++, you should do that anyway, but it kind of forces the issue.

It is due to ad-blocker.When project files names contains words like 'ad' then ad-blockers also block theses files to load.

Best solution is that never save any files with these name keys.

Open up a command prompt and type java -jar jbpm-installer-3.2.7.jar

I made an update of the actual answer.

This seems to be working on firefox and chrome: http://jsfiddle.net/gatsbimantico/QJeB7/1/embedded/result/

.x{
columns: 5em;
-webkit-columns: 5em; /* Safari and Chrome */
-moz-columns: 5em; /* Firefox */
}
.x li{
    float:left;
    break-inside: avoid-column;
    -webkit-column-break-inside: avoid;  /* Safari and Chrome */
}

Note: The float property seems to be the one making the block behaviour.

Here's the way I did it, using the way I have done it in other languages:

private string ToStringList<T>(IEnumerable<T> list, string delimiter)
{
  var sb = new StringBuilder();
  string separator = String.Empty;
  foreach (T value in list)
  {
    sb.Append(separator).Append(value);
    separator = delimiter;
  }
  return sb.ToString();
}

1. Make sure the project is extracted on your hard disk.
2. In Eclipse go to the menu: File->New->Project.
3. Select "General->Project" and click on the next button.
4. Enter the project name in the "Project name:" field
5. Disable "Use default location" Click on the "Browse ..." button and select the folder that contains the project (the one from step 1)
6. Click on the "Finish" button
7. Right-click with the mouse on you're new project and click "Configure->Convert to AngularJS Project.."
8. Enable you're project goodies and click on the "OK" button.

Hi curious you can validate your google recaptcha at client side also 100% work for me to verify your google recaptcha just see below code
This code at the html body:

 <div class="g-recaptcha" id="rcaptcha" style="margin-left: 90px;" data-sitekey="my_key"></div>
 <span id="captcha" style="margin-left:100px;color:red" />

This code put at head section on call get_action(this) method form button:

function get_action(form) {

var v = grecaptcha.getResponse();
if(v.length == 0)
{
    document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
    return false;
}
 if(v.length != 0)
 {
    document.getElementById('captcha').innerHTML="Captcha completed";
    return true; 
 }
}

Do

apachectl -k graceful

Check this link for more information : http://www.electrictoolbox.com/article/apache/restart-apache/

You can try this

    $('.checkAll').on('click',function(){
        $('.checkboxes').prop('checked',$(this).prop("checked"));
    });`

Class .checkAll is a checkbox which controls the bulk action

The basis logic for such behavior is that Generics follow a mechanism of type erasure. So at run time you have no way if identifying the type of collection unlike arrays where there is no such erasure process. So coming back to your question...

So suppose there is a method as given below:

add(List<Animal>){
    //You can add List<Dog or List<Cat> and this will compile as per rules of polymorphism
}

Now if java allows caller to add List of type Animal to this method then you might add wrong thing into collection and at run time too it will run due to type erasure. While in case of arrays you will get a run time exception for such scenarios...

Thus in essence this behavior is implemented so that one cannot add wrong thing into collection. Now I believe type erasure exists so as to give compatibility with legacy java without generics....

Try to use the following approach (it works for me):

@Query("SELECT u.username FROM User u WHERE u.username LIKE CONCAT('%',:username,'%')")
List<String> findUsersWithPartOfName(@Param("username") String username);

Notice: The table name in JPQL must start with a capital letter.

Once you have a library downloaded you can execute this from the MS-DOS command box:

python setup.py install

The setup.py is located inside every library main folder.

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.

When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.

When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).

A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

you have to make you're function static like this

namespace Add_Function
{
  class Program
  {
    public static void(string[] args)
    {
       int a;
       int b;
       int c;

       Console.WriteLine("Enter value of 'a':");
       a = Convert.ToInt32(Console.ReadLine());

       Console.WriteLine("Enter value of 'b':");
       b = Convert.ToInt32(Console.ReadLine());

       //why can't I not use it this way?
       c = Add(a, b);
       Console.WriteLine("a + b = {0}", c);
    }
    public static int Add(int x, int y)
    {
        int result = x + y;
        return result;
     }
  }
}

you can do Program.Add instead of Add you also can make a new instance of Program by going like this

Program programinstance = new Program();

I found a much simpler alternative way to generating soap message. Given a Person Object:

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
  private String name;
  private int age;
  private String address; //setter and getters below
}

Below is a simple Soap Message Generator:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

@Slf4j
public class SoapGenerator {

  protected static final ObjectMapper XML_MAPPER = new XmlMapper()
      .enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
      .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
      .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
      .registerModule(new JavaTimeModule());

  private static final String SOAP_BODY_OPEN = "<soap:Body>";
  private static final String SOAP_BODY_CLOSE = "</soap:Body>";
  private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
  private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";

  public static String soapWrap(String xml) {
    return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
  }

  public static String soapUnwrap(String xml) {
    return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
  }
}

You can use by:

 public static void main(String[] args) throws Exception{
        Person p = new Person();
        p.setName("Test");
        p.setAge(12);

        String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
        log.info("Generated String");
        log.info(xml);
      }

It sounds like you just want to reset to C; that is make the tree:

A-B-C

You can do that with reset:

git reset --hard HEAD~3

_{(Note: You said three commits ago so that's what I wrote; in your example C is only two commits ago, so you might want to use HEAD~2)}

You can also use revert if you want, although as far as I know you need to do the reverts one at a time:

git revert HEAD     # Reverts E
git revert HEAD~2   # Reverts D

That will create a new commit F that's the same contents as D, and G that's the same contents as C. You can rebase to squash those together if you want

If your detached HEAD is a fast forward of master and you just want the commits upstream, you can

git push origin HEAD:master

to push directly, or

git checkout master && git merge [ref of HEAD]

will merge it back into your local master.

# Original code
df = pd.DataFrame({'a': [1, 2, 3, 'bad', 5],
                   'b': [0.1, 0.2, 0.3, 0.4, 0.5],
                   'item': ['a', 'b', 'c', 'd', 'e']})
df = df.set_index('item')

Convert to numeric using 'coerce' which fills bad values with 'nan'

a = pd.to_numeric(df.a, errors='coerce')

Use isna to return a boolean index:

idx = a.isna()

Apply that index to the data frame:

df[idx]

output

Returns the row with the bad data in it:

        a    b
item          
d     bad  0.4

This code snippet:

int& func1()
{
    int i;
    i = 1;
    return i;
}

will not work because you're returning an alias (a reference) to an object with a lifetime limited to the scope of the function call. That means once func1() returns, int i dies, making the reference returned from the function worthless because it now refers to an object that doesn't exist.

int main()
{
    int& p = func1();
    /* p is garbage */
}

The second version does work because the variable is allocated on the free store, which is not bound to the lifetime of the function call. However, you are responsible for deleteing the allocated int.

int* func2()
{
    int* p;
    p = new int;
    *p = 1;
    return p;
}

int main()
{
    int* p = func2();
    /* pointee still exists */
    delete p; // get rid of it
}

Typically you would wrap the pointer in some RAII class and/or a factory function so you don't have to delete it yourself.

In either case, you can just return the value itself (although I realize the example you provided was probably contrived):

int func3()
{
    return 1;
}

int main()
{
    int v = func3();
    // do whatever you want with the returned value
}

Note that it's perfectly fine to return big objects the same way func3() returns primitive values because just about every compiler nowadays implements some form of return value optimization:

class big_object 
{ 
public:
    big_object(/* constructor arguments */);
    ~big_object();
    big_object(const big_object& rhs);
    big_object& operator=(const big_object& rhs);
    /* public methods */
private:
    /* data members */
};

big_object func4()
{
    return big_object(/* constructor arguments */);
}

int main()
{
     // no copy is actually made, if your compiler supports RVO
    big_object o = func4();    
}

Interestingly, binding a temporary to a const reference is perfectly legal C++.

int main()
{
    // This works! The returned temporary will last as long as the reference exists
    const big_object& o = func4();    
    // This does *not* work! It's not legal C++ because reference is not const.
    // big_object& o = func4();  
}

TLDR: ??F on MacOS will open "Find in path" dialog.

First of all, this IDEA has a nice "Find Usages" command. It can be found in the context menu, when the cursor is on some field, method, etc.

It's context-aware, and as far as I know, is the best way to find class, method or field usage.

Alternatively, you can use the

Edit > Find > Find in path…

dialog, which allows you to search the whole workspace.

Also in IDEA 13 there is an awesome "Search Everywhere" option, by default called by double Shift. It allows you to search in project, files, classes, settings, and so on.

Also you can search from Project Structure dialog with "Find in Path…". Just call it by right mouse button on concrete directory and the search will be scoped, only inside that directory and it's sub-directory.

Enjoy!

CSS is designed to describe the presentation of documents. It has a few features for changing that presentation in reaction to user interaction (primarily :hover for indicating that you are now pointing at something interactive).

Making something draggable isn't a simple matter of presentation. It is firmly in the territory of interactivity logic, which is handled by JavaScript.

What you want is not achievable.

On any other element, I would use the scrollHeight of the DOM object and set the height accordingly. I don't know if this would work on an iframe (because they're a bit kooky about everything) but it's certainly worth a try.

Edit: Having had a look around, the popular consensus is setting the height from within the iframe using the offsetHeight:

function setHeight() {
    parent.document.getElementById('the-iframe-id').style.height = document['body'].offsetHeight + 'px';
}

And attach that to run with the iframe-body's onLoad event.

This is a straight way to do this.

The case is simple, but finally quite common ( typical thumbnails scroller with fixed cell size and fixed gap between cells )

var itemCellSize: CGSize = <your cell size>
var itemCellsGap: CGFloat = <gap in between>

override func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    let pageWidth = (itemCellSize.width + itemCellsGap)
    let itemIndex = (targetContentOffset.pointee.x) / pageWidth
    targetContentOffset.pointee.x = round(itemIndex) * pageWidth - (itemCellsGap / 2)
}

// CollectionViewFlowLayoutDelegate

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    return itemCellSize
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return itemCellsGap
}

Note that there is no reason to call a scrollToOffset or dive into layouts. The native scrolling behaviour already does everything.

Cheers All :)

Here we go:

DateTime time = DateTime.Now;
Console.WriteLine(time.Day + "-" + time.Month + "-" + time.Year);

WORKS! :)

I suppose you have a list of words (word_list) from which you want to remove stopwords. You could do something like this:

filtered_word_list = word_list[:] #make a copy of the word_list
for word in word_list: # iterate over word_list
  if word in stopwords.words('english'): 
    filtered_word_list.remove(word) # remove word from filtered_word_list if it is a stopword

Another possible solution, in case you're looking for all the words in a given string, which contain a number

Pattern

\w*\d{1,}\w*

• \w* - Matches 0 or more instances of [A-Za-z0-9_]
• \d{1,} - Matches 1 or more instances of a number
• \w* - Matches 0 or more instances of [A-Za-z0-9_]

The whole point in \w* is to allow not having a character in the beginning or at the end of a word. This enables capturing the first and last words in the text.

If the goal here is to only get the numbers without the words, you can omit both \w*.

Given the string

Hello world 1 4m very happy to be here, my name is W1lly W0nk4

Matches

1 4m W1lly W0nk4

Check this example in regexr - https://regexr.com/5ff7q

If you just want a really simple way to do this.. Heres a script I have used in the past

select 'drop table '||table_name||' cascade constraints;' from user_tables;

This will print out a series of drop commands for all tables in the schema. Spool the result of this query and execute it.

Source: https://forums.oracle.com/forums/thread.jspa?threadID=614090

Likewise if you want to clear more than tables you can edit the following to suit your needs

select 'drop '||object_type||' '|| object_name || ';' from user_objects where object_type in ('VIEW','PACKAGE','SEQUENCE', 'PROCEDURE', 'FUNCTION', 'INDEX')

$(this).bind('input propertychange', function() {
        //your code here
    });

This is works for typing, paste, right click mouse paste etc.

More then one condition statement is needed to use OR(||) operator in if conditions and notation is ||.

if(condition || condition){ 
   some stuff
}

yourTableView.rowHeight = UITableViewAutomaticDimension

Try this.

There is a whole new approach that you may want to consider if what you're after is the power and performance of stored procedures, and the rapid development that tools like Entity Framework provide.

I've taken SQL+ for a test drive on a small project, and it is really something special. You basically add what amounts to comments to your SQL routines, and those comments provide instructions to a code generator, which then builds a really nice object oriented class library based on the actual SQL routine. Kind of like entity framework in reverse.

Input parameters become part of an input object, output parameters and result sets become part of an output object, and a service component provides the method calls.

If you want to use stored procedures, but still want rapid development, you might want to have a look at this stuff.

CROSS APPLY to the rescue:

SELECT Orders.OrderNumber, topline.Quantity, topline.Description
FROM Orders
cross apply
(
    select top 1 Description,Quantity
    from LineItems 
    where Orders.OrderID = LineItems.OrderID
)topline

You can also add the order by of your choice.

Why not just make the server return the names?

["Woodland Hills", "none", "Los Angeles", "Laguna Hills"]

Then create the <option> elements using JavaScript.

$.ajax({
    url:'suggest.html',
    type:'POST',
    data: 'q=' + str,
    dataType: 'json',
    success: function( json ) {
        $.each(json, function(i, value) {
            $('#myselect').append($('<option>').text(value).attr('value', value));
        });
    }
});

def some_view(request):
    if request.method == 'POST':
        form = SomeForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
    else:
        form = SomeForm()
    return render(request, 'some_form.html', {'form': form})

You can simply do a replace in your string like

Str.Replace(@"\\",@"\");

See Branching Statements for more details and code samples:

break

The break statement has two forms: labeled and unlabeled. You saw the unlabeled form in the previous discussion of the switch statement. You can also use an unlabeled break to terminate a for, while, or do-while loop [...]

An unlabeled break statement terminates the innermost switch, for, while, or do-while statement, but a labeled break terminates an outer statement.

continue

The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. [...]

A labeled continue statement skips the current iteration of an outer loop marked with the given label.

This will get your buttons and labels next to each other, at least. I believe the second part can't be done in css alone, and will need javascript. I found a page that might help you with that part as well, but I don't have time right now to try it out: http://www.webmasterworld.com/forum83/6942.htm

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

I created a WSGI middleware that stores the raw body from the environ['wsgi.input'] stream. I saved the value in the WSGI environ so I could access it from request.environ['body_copy'] within my app.

This isn't necessary in Werkzeug or Flask, as request.get_data() will get the raw data regardless of content type, but with better handling of HTTP and WSGI behavior.

This reads the entire body into memory, which will be an issue if for example a large file is posted. This won't read anything if the Content-Length header is missing, so it won't handle streaming requests.

from io import BytesIO

class WSGICopyBody(object):
    def __init__(self, application):
        self.application = application

    def __call__(self, environ, start_response):
        length = int(environ.get('CONTENT_LENGTH') or 0)
        body = environ['wsgi.input'].read(length)
        environ['body_copy'] = body
        # replace the stream since it was exhausted by read()
        environ['wsgi.input'] = BytesIO(body)
        return self.application(environ, start_response)

app.wsgi_app = WSGICopyBody(app.wsgi_app)

request.environ['body_copy']

If you want SSMS to maintain a query history, use the SSMS Tool Pack add on.

If you want to monitor the SQL Server for currently running queries, use SQL PRofiler as other have already suggested.

This worked for me:

.table tbody tr:hover td, .table tbody tr:hover th {

I had a similar issue. The Maven projects have different structure than "Dynamic Web Projects". Eclipse knows only how to deploy the Dynamic Web Projects (project structure used by Web Tools Platform).

In order to solve this and tell Eclipse how to deploy a "maven style" projects, you have to install the M2E Eclipse WTP plugin (I suppose you are already using the m2e plugin).

To install: Preferences->Maven->Discovery->Open Catalog and choose the WTP plugin.

After reinstalling, you will be able to "run on server" those projects which are maven web projects.

Hope that helps,

I would say angular.copy(source); in your situation is unnecessary if later on you do not use is it without a destination angular.copy(source, [destination]);.

If a destination is provided, all of its elements (for arrays) or properties (for objects) are deleted and then all elements/properties from the source are copied to it.

https://docs.angularjs.org/api/ng/function/angular.copy

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

Complete example : Fix certificate problem in HTTPS

1. download new xampp apachefriends
2. install it
3. remove all VPN app
4. open folder XAMPP run setup_xampp.bat
5. run xampp-control.exe

Try this, Its working:

mysql -h {hostname} -u{username} -p{password} -N -e "{query to execute}"

Think about somebody doing help(yourmodule) at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help in terms of amount of information). So if you have in x.py:

"""This module does blah blah."""

class Blah(object):
  """This class does blah blah."""

then:

>>> import x; help(x)

shows:

Help on module x:

NAME
    x - This module does blah blah.

FILE
    /tmp/x.py

CLASSES
    __builtin__.object
        Blah

    class Blah(__builtin__.object)
     |  This class does blah blah.
     |  
     |  Data and other attributes defined here:
     |  
     |  __dict__ = <dictproxy object>
     |      dictionary for instance variables (if defined)
     |  
     |  __weakref__ = <attribute '__weakref__' of 'Blah' objects>
     |      list of weak references to the object (if defined)

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).

I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.

Try

SELECT * FROM table WHERE arr @> ARRAY['s']::varchar[]

Yes you can use setValue to set value for edit/update purpose.

this.personalform.setValue({
      name: items.name,
      address: {
        city: items.address.city,
        country: items.address.country
      }
    });

You can refer http://musttoknow.com/use-angular-reactive-form-addinsert-update-data-using-setvalue-setpatch/ to understand how to use Reactive forms for add/edit feature by using setValue. It saved my time

Try using a simple HttpResponseMessage with its Content property set to a StreamContent:

// using System.IO;
// using System.Net.Http;
// using System.Net.Http.Headers;

public HttpResponseMessage Post(string version, string environment,
    string filetype)
{
    var path = @"C:\Temp\test.exe";
    HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
    var stream = new FileStream(path, FileMode.Open, FileAccess.Read);
    result.Content = new StreamContent(stream);
    result.Content.Headers.ContentType = 
        new MediaTypeHeaderValue("application/octet-stream");
    return result;
}

A few things to note about the stream used:

• You must not call stream.Dispose(), since Web API still needs to be able to access it when it processes the controller method's result to send data back to the client. Therefore, do not use a using (var stream = …) block. Web API will dispose the stream for you.

• Make sure that the stream has its current position set to 0 (i.e. the beginning of the stream's data). In the above example, this is a given since you've only just opened the file. However, in other scenarios (such as when you first write some binary data to a MemoryStream), make sure to stream.Seek(0, SeekOrigin.Begin); or set stream.Position = 0;

• With file streams, explicitly specifying FileAccess.Read permission can help prevent access rights issues on web servers; IIS application pool accounts are often given only read / list / execute access rights to the wwwroot.

If using eclipse,

Under.settings click on org.eclipse.wst.common.project.facet.core.xml

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <installed facet="java" version="1.7"/>
</faceted-project>

Change the version to the correct version.

You use

#main_text .title {
  /* Properties */
}

If you just put a space between the selectors, styles will apply to all children (and children of children) of the first. So in this case, any child element of #main_text with the class name title. If you use > instead of a space, it will only select the direct child of the element, and not children of children, e.g.:

#main_text > .title {
  /* Properties */
}

Either will work in this case, but the first is more typically used.

If you're looking for currency formatting (which you didn't specify, but it seems that is what you're looking for) try the NumberFormat class. It's very simple:

double d = 2.3d;
NumberFormat formatter = NumberFormat.getCurrencyInstance();
String output = formatter.format(d);

Which will output (depending on locale):

$2.30

Also, if currency isn't required (just the exact two decimal places) you can use this instead:

NumberFormat formatter = NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String output = formatter.format(d);

Which will output 2.30

I now found solution by using mysqli instead of mysql.

<?php 

// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");

//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");

//loop the result set
while ($row = mysqli_fetch_array($result)){     
  echo $row[0] . " - " . + $row[1]; 
}

I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array.

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

Beautiful set of stencils from Microsoft here.

Some tips:

• Read this tutorial: Creating an Input Method
• clone this repo: LatinIME

About your questions:

An inputMethod is basically an Android Service, so yes, you can do HTTP and all the stuff you can do in a Service.

You can open Activities and dialogs from the InputMethod. Once again, it's just a Service.

I've been developing an IME, so ask again if you run into an issue.

What you've done by following those directions is created an entirely new Python installation, separate from the system Python that is managed by Ubuntu packages.

Modules you had installed in the system Python (e.g. installed via packages, or by manual installation using the system Python to run the setup process) will not be available, since your /usr/local-based python is configured to look in its own module directories, not the system Python's.

You can re-add missing modules now by building them and installing them using your new /usr/local-based Python.

Mike Goodwin answer is great but it seemed, when I tried it, that it was aimed at MVC5/WebApi 2.1. The dependencies for Microsoft.AspNet.WebApi.Cors didn't play nicely with my MVC4 project.

The simplest way to enable CORS on WebApi with MVC4 was the following.

Note that I have allowed all, I suggest you limit the Origin's to just the clients you want your API to serve. Allowing everything is a security risk.

Web.config:

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, HEAD" />
        <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
      </customHeaders>
    </httpProtocol>
</system.webServer>

BaseApiController.cs:

We do this to allow the OPTIONS http verb

 public class BaseApiController : ApiController
  {
    public HttpResponseMessage Options()
    {
      return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
    }
  }

Rather than giving an error or some sentinel value (e.g. '?') for inputs outside of 0-25, I sometimes find it useful to have a well-defined string for all integers. I like to use the following:

   0 ->    A
   1 ->    B
   2 ->    C
 ...
  25 ->    Z
  26 ->   AA
  27 ->   AB
  28 ->   AC
 ...
 701 ->   ZZ
 702 ->  AAA
 ...

This can be extended to negatives as well:

  -1 ->   -A
  -2 ->   -B
  -3 ->   -C
 ...
 -26 ->   -Z
 -27 ->  -AA
 ...

Java Code:

public static String toAlphabetic(int i) {
    if( i<0 ) {
        return "-"+toAlphabetic(-i-1);
    }

    int quot = i/26;
    int rem = i%26;
    char letter = (char)((int)'A' + rem);
    if( quot == 0 ) {
        return ""+letter;
    } else {
        return toAlphabetic(quot-1) + letter;
    }
}

Python code, including the ability to use alphanumeric (base 36) or case-sensitive (base 62) alphabets:

def to_alphabetic(i,base=26):
    if base < 0 or 62 < base:
        raise ValueError("Invalid base")

    if i < 0:
        return '-'+to_alphabetic(-i-1)

    quot = int(i)/base
    rem = i%base
    if rem < 26:
        letter = chr( ord("A") + rem)
    elif rem < 36:
        letter = str( rem-26)
    else:
        letter = chr( ord("a") + rem - 36)
    if quot == 0:
        return letter
    else:
        return to_alphabetic(quot-1,base) + letter

The book has a note how to find help on tag sets, e.g.:

nltk.help.upenn_tagset()

Others are probably similar. (Note: Maybe you first have to download tagsets from the download helper's Models section for this)

This is what I used to copy some resource files: the copy-files is an empty target to ignore errors

 add_custom_target(copy-files ALL
    COMMAND ${CMAKE_COMMAND} -E copy_directory
    ${CMAKE_BINARY_DIR}/SOURCEDIRECTORY
    ${CMAKE_BINARY_DIR}/DESTINATIONDIRECTORY
    )

Use the basename command to extract the filename from the path:

[/tmp]$ export fspec=/exp/home1/abc.txt 
[/tmp]$ fname=`basename $fspec`
[/tmp]$ echo $fname
abc.txt

This is very confusing for beginners. The basic difference is map emits one item for each entry in the list and flatMap is basically a map + flatten operation. To be more clear, use flatMap when you require more than one value, eg when you are expecting a loop to return arrays, flatMap will be really helpful in this case.

I have written a blog about this, you can check it out here.

mod_php is a PHP interpreter.

From docs, one important catch of mod_php is,

"mod_php is not thread safe and forces you to stick with the prefork mpm (multi process, no threads), which is the slowest possible configuration"

For the case where you are not adding to the end of the tuple

>>> a=(1,2,3,5,6)
>>> a=a[:3]+(4,)+a[3:]
>>> a
(1, 2, 3, 4, 5, 6)
>>> 

hash.each do |key, array|
  puts "#{key}-----"
  puts array
end

Regarding order I should add, that in 1.8 the items will be iterated in random order (well, actually in an order defined by Fixnum's hashing function), while in 1.9 it will be iterated in the order of the literal.

The following tables are store WooCommerce products database :

• wp_posts -

  The core of the WordPress data is the posts. It is stored a post_type like product or variable_product.

• wp_postmeta-

  Each post features information called the meta data and it is stored in the wp_postmeta. Some plugins may add their own information to this table like WooCommerce plugin store product_id of product in wp_postmeta table.

Product categories, subcategories stored in this table :

• wp_terms
• wp_termmeta
• wp_term_taxonomy
• wp_term_relationships
• wp_woocommerce_termmeta

following Query Return a list of product categories

SELECT wp_terms.* 
    FROM wp_terms

export PATH=/usr/pgsql-9.2/bin:$PATH

The program executable psql is in the directory /usr/pgsql-9.2/bin, and that directory is not included in the path by default, so we have to tell our shell (terminal) program where to find psql. When most packages are installed, they are added to an existing path, such as /usr/local/bin, but not this program.

So we have to add the program's path to the shell PATH variable if we do not want to have to type the complete path to the program every time we execute it.

This line should typically be added to theshell startup script, which for the bash shell will be in the file ~/.bashrc.

You could simply look in the Active Record Rake tasks as that is where I believe they live as in this file. https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/lib/active_record/tasks/database_tasks.rb

What they do is your question right?

That depends on where they come from and this is just and example to show that they vary depending upon the task. Here we have a different file full of tasks.

https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/Rakefile

which has these tasks.

namespace :db do
  task create: ["db:mysql:build", "db:postgresql:build"]
  task drop: ["db:mysql:drop", "db:postgresql:drop"]

This may not answer your question but could give you some insight into go ahead and look the source over especially the rake files and tasks. As they do a pretty good job of helping you use rails they don't always document the code that well. We could all help there if we know what it is supposed to do.

I wanted to solve this simple solution in a straightforward way of writing, with a little bit of a pain of computational expenses... but isn't it a trivial solution with a minimum variable definition, is it?

function uniq(ArrayObjects){
  var out = []
  ArrayObjects.map(obj => {
    if(_.every(out, outobj => !_.isEqual(obj, outobj))) out.push(obj)
  })
  return out
}

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

Selected answer works for one drop down menu only. For multiple solution would be:

$('body').click(function(event){
   $dropdowns.not($dropdowns.has(event.target)).hide();
});

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

You can handle in many ways in Selenium.

You can use direct click operation to Select values

or

you can write general xpath to match all values from calender and click on specific date as per requirement.

I have written detailed post on it.

Hope it will help

For the others, also check your stored procedure. In my case in my stored procedure CustomSearch I accidentally declared not enough length for my column, so when I entered a big data I received that error even though I have a big length on my database. I just changed the length of my column in my custom search the error goes away. This is just for the reminder. Thanks.

In Java there are two basic types in the JVM. 1) Primitive types and 2) Reference Types. int is a primitive type and Integer is a class type (which is kind of reference type).

Primitive values do not share state with other primitive values. A variable whose type is a primitive type always holds a primitive value of that type.

int aNumber = 4;
int anotherNum = aNumber;
aNumber += 6;
System.out.println(anotherNum); // Prints 4

An object is a dynamically created class instance or an array. The reference values (often just references) are pointers to these objects and a special null reference, which refers to no object. There may be many references to the same object.

Integer aNumber = Integer.valueOf(4);
Integer anotherNumber = aNumber; // anotherNumber references the 
                                 // same object as aNumber

Also in Java everything is passed by value. With objects the value that is passed is the reference to the object. So another difference between int and Integer in java is how they are passed in method calls. For example in

public int add(int a, int b) {
    return a + b;
}
final int two = 2;
int sum = add(1, two);

The variable two is passed as the primitive integer type 2. Whereas in

public int add(Integer a, Integer b) {
    return a.intValue() + b.intValue();
}
final Integer two = Integer.valueOf(2);
int sum = add(Integer.valueOf(1), two);

The variable two is passed as a reference to an object that holds the integer value 2.

@WolfmanDragon: Pass by reference would work like so:

public void increment(int x) {
  x = x + 1;
}
int a = 1;
increment(a);
// a is now 2

When increment is called it passes a reference (pointer) to variable a. And the increment function directly modifies variable a.

And for object types it would work as follows:

public void increment(Integer x) {
  x = Integer.valueOf(x.intValue() + 1);
}
Integer a = Integer.valueOf(1);
increment(a);
// a is now 2

Do you see the difference now?

All of that above can work but for a quick and easy fix you can use the time_formatter package.

Using this package you can convert the epoch to human-readable time.

String convertTimeStamp(timeStamp){
//Pass the epoch server time and the it will format it for you 
   String formatted = formatTime(timeStamp).toString();
   return formatted;
}
//Then you can display it
Text(convertTimeStamp['createdTimeStamp'])//< 1 second : "Just now" up to < 730 days : "1 year"

Here you can check the format of the output that is going to be displayed: Formats

Simple method:

public boolean isBlank(String value) {
    return (value == null || value.equals("") || value.equals("null") || value.trim().equals(""));
}


public boolean isOnlyNumber(String value) {
    boolean ret = false;
    if (!isBlank(value)) {
        ret = value.matches("^[0-9]+$");
    }
    return ret;
}

You can get posted form data from request.form and query string data from request.args.

myvar =  request.form["myvar"]

myvar = request.args["myvar"]

Every element of your vector is a float[4], so when you resize every element needs to default initialized from a float[4]. I take it you tried to initialize with an int value like 0?

Try:

static float zeros[4] = {0.0, 0.0, 0.0, 0.0};
myvector.resize(newsize, zeros);

The == operator compares if the objects are the same instance. The equals() oerator compares the state of the objects (e.g. if all attributes are equal). You can even override the equals() method to define yourself when an object is equal to another.

You can use XML literals to sort of do this:

Dim s = <sql>
  Create table article
  (articleID int  -- sql comment
  ,articleName varchar(50)  <comment text="here's an xml comment" />
  )
</sql>.Value

warning: XML text rules apply, like &amp; for ampersand, &lt; for <, etc.

Dim alertText = "Hello World"
Dim js = <script>
          $(document).ready(function() {
           alert('<%= alertText %>');
          });
         </script>.ToString  'instead of .Value includes <script> tag

note: the above is problematic when it includes characters that need to be escaped. Better to use "<script>"+js.Value+"</script>"

Yes. This is absolutely correct.

You could see ManualResetEvent as a way to indicate state. Something is on (Set) or off (Reset). An occurrence with some duration. Any thread waiting for that state to happen can proceed.

An AutoResetEvent is more comparable to a signal. A one shot indication that something has happened. An occurrence without any duration. Typically but not necessarily the "something" that has happened is small and needs to be handled by a single thread - hence the automatic reset after a single thread have consumed the event.

Use a column to let each date be shown as month number; another column for day number:

      A      B       C         D
   -----  ----- ----------- --------
1     8      6    8/6/2010   12.70
2     8      7    8/7/2010   10.50
3     8      7    8/7/2010    7.10
4     8      9    8/9/2010   10.50
5     8     10   8/10/2010   15.00

The formula for A1 is =Month(C1)

The formula for B1 is =Day(C1)

For Month sums, put the month number next to each month:

      E      F         G     
   -----  ----- -------------  
1     7    July   $1,000,010 
2     8     Aug   $1,200,300 

The formula for G1 is =SumIf($A$1:$A$100, E1, $D$1:$D$100). This is a portable formula; just copy it down.

Total for the day will be be a bit more complicated, but you can probably see how to do it.

If I want to exit a for-to loop, I just set the index beyond the limit:

    For i = 1 To max
        some code
        if this(i) = 25 Then i = max + 1
        some more code...
    Next`

Poppa.

For System.Timers.Timer:

See Brian Gideon's answer below

For System.Threading.Timer:

MSDN Documentation on Timers states:

The System.Threading.Timer class makes callbacks on a ThreadPool thread and does not use the event model at all.

So indeed the timer elapses on a different thread.

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

A simple way to get this error is to type (a) below, meaning to type (b)

(a) $this->my->variable

(b) $this->my_variable

Trivial, but very easily overlooked and hard to spot if you are not looking for it.

Disclaimer: I am the developer of the Gradle Test Logger Plugin.

You can simply use the Gradle Test Logger Plugin to print beautiful logs on the console. The plugin uses sensible defaults to satisfy most users with little or no configuration but also offers a number of themes and configuration options to suit everyone.

Examples

Standard theme

Mocha theme

Usage

plugins {
    id 'com.adarshr.test-logger' version '<version>'
}

Make sure you always get the latest version from Gradle Central.

Configuration

You don't need any configuration at all. However, the plugin offers a few options. This can be done as follows (default values shown):

testlogger {
    // pick a theme - mocha, standard, plain, mocha-parallel, standard-parallel or plain-parallel
    theme 'standard'

    // set to false to disable detailed failure logs
    showExceptions true

    // set to false to hide stack traces
    showStackTraces true

    // set to true to remove any filtering applied to stack traces
    showFullStackTraces false

    // set to false to hide exception causes
    showCauses true

    // set threshold in milliseconds to highlight slow tests
    slowThreshold 2000

    // displays a breakdown of passes, failures and skips along with total duration
    showSummary true

    // set to true to see simple class names
    showSimpleNames false

    // set to false to hide passed tests
    showPassed true

    // set to false to hide skipped tests
    showSkipped true

    // set to false to hide failed tests
    showFailed true

    // enable to see standard out and error streams inline with the test results
    showStandardStreams false

    // set to false to hide passed standard out and error streams
    showPassedStandardStreams true

    // set to false to hide skipped standard out and error streams
    showSkippedStandardStreams true

    // set to false to hide failed standard out and error streams
    showFailedStandardStreams true
}

I hope you will enjoy using it.

You could have a look at Normalizer::normalize(), see here. It just needs to load the intl module for PHP

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Keep in mind that there are processes on the database which may not currently support a session.

If you're interested in all processes you'll want to look to v$process (or gv$process on RAC)

Between execution of left != null and queue.add(left) another thread could have changed the value of left to null.

To work around this you have several options. Here are some:

1. Use a local variable with smart cast:

    val node = left
    if (node != null) {
        queue.add(node)
    }
   

2. Use a safe call such as one of the following:

    left?.let { node -> queue.add(node) }
    left?.let { queue.add(it) }
    left?.let(queue::add)
   

3. Use the Elvis operator with return to return early from the enclosing function:

    queue.add(left ?: return)
   

   Note that break and continue can be used similarly for checks within loops.

The pathname for a file or directory is specified using the naming conventions of the host system. However, the File class defines platform-dependent constants that can be used to handle file and directory names in a platform-independent way.

Files.seperator defines the character or string that separates the directory and the file com- ponents in a pathname. This separator is '/', '\' or ':' for Unix, Windows, and Macintosh, respectively.

You could always use ADO to write the results out to the worksheet cells from a recordset object

This is a variation of something I learned several years back. Apparently, this is popular with C++ developers.

First off, I think I know why you want to break out of IF blocks. For me, I don't like a bunch of nested blocks because 1) it makes the code look messy and 2) it can be a pia to maintain if you have to move logic around.

Consider a do/while loop instead:

public void Method()
{
    bool something = true, something2 = false;

    do
    {
        if (!something) break;

        if (something2) break;

    } while (false);
}

The do/while loop is guaranteed to run only once just like an IF block thanks to the hardcoded false condition. When you want to exit early, just break.

How to get Color from Hexadecimal color code using .NET?

This I think is what you are after, hope it answers your question.

To get your code to work use Convert.ToByte instead of Convert.ToInt...

string colour = "#ffaacc";

Color.FromRgb(
Convert.ToByte(colour.Substring(1,2),16),
Convert.ToByte(colour.Substring(3,2),16),
Convert.ToByte(colour.Substring(5,2),16));

I sort of re-discovered legit because of this issue (OS X only). Now all I use when branching are these two commands:

legit publish [<branch>] Publishes specified branch to the remote. (alias: pub)

legit unpublish <branch> Removes specified branch from the remote. (alias: unp)

SublimeGit comes with legit support by default, which makes whole branching routine as easy as pressing Ctrl-b.

        public static void main(String args[])throws IOException
        {
        InputStreamReader read = new InputStreamReader(System.in);
        BufferedReader in = new BufferedReader(read);
        int number;
                System.out.println("Enter the number");
                number = Integer.parseInt(in.readLine());

}

According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.

Request.Form is a NameValueCollection. In NameValueCollection you can find the GetAllValues() method.

By the way the LINQ method also works.

Make sure you format the string like this or it wont work

 $content = "BEGIN:VCALENDAR\n".
            "VERSION:2.0\n".

            "BEGIN:VEVENT\n".
            "UID:".uniqid()."\n".
            "DTSTAMP:".$time."\n".

            "END:VEVENT\n".
            "END:VCALENDAR";

I would propose the use of a private friend method which implements the application logic of the constructor and is the called by the various constructors. Here is an example:

Assume we have a class called StreamArrayReader with some private fields:

private:
    istream * in;
      // More private fields

And we want to define the two constructors:

public:
    StreamArrayReader(istream * in_stream);
    StreamArrayReader(char * filepath);
    // More constructors...

Where the second one simply makes use of the first one (and of course we don't want to duplicate the implementation of the former). Ideally, one would like to do something like:

StreamArrayReader::StreamArrayReader(istream * in_stream){
    // Implementation
}

StreamArrayReader::StreamArrayReader(char * filepath) {
    ifstream instream;
    instream.open(filepath);
    StreamArrayReader(&instream);
    instream.close();
}

However, this is not allowed in C++. For that reason, we may define a private friend method as follows which implements what the first constructor is supposed to do:

private:
  friend void init_stream_array_reader(StreamArrayReader *o, istream * is);

Now this method (because it's a friend) has access to the private fields of o. Then, the first constructor becomes:

StreamArrayReader::StreamArrayReader(istream * is) {
    init_stream_array_reader(this, is);
}

Note that this does not create multiple copies for the newly created copies. The second one becomes:

StreamArrayReader::StreamArrayReader(char * filepath) {
    ifstream instream;
    instream.open(filepath);
    init_stream_array_reader(this, &instream);
    instream.close();
}

That is, instead of having one constructor calling another, both call a private friend!

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

REST is a generic design technique used to describe how a web service can be accessed. Using REST you can make http requests to get data. If you try it in your browser it would be just like going to a website except instead of returning a web page you would get back XML. Some services will also return data in JSON format which is easier to use with Javascript.

OData is a specific technology that exposes data through REST.

If you want to sum it up real quick, think of it as:

• REST - design pattern
• OData - enabling technology

All this might not help say when you use rails remote form button to simulate click to. I tried to port nice event simulation from prototype here: my snippets. Just did it and it works for me.

This typically happens when mixing (in the same jsp page) static jsp import:

<%@include file="...

with dynamic jsp import:

<jsp:include page="...

and your type has been already imported by the "static imported" jsp. When the same type needs to be used (and then imported) by the "dynamically imported" jsp -> this generate the Exception: "Only a type can be imported..."

This is more concise:

<?php echo get_post_field('post_content', $post->ID); ?>

and this even more:

<?= get_post_field('post_content', $post->ID) ?>

I used this solution to get realtime output on a subprocess. This loop will stop as soon as the process completes leaving out a need for a break statement or possible infinite loop.

sub_process = subprocess.Popen(my_command, close_fds=True, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

while sub_process.poll() is None:
    out = sub_process.stdout.read(1)
    sys.stdout.write(out)
    sys.stdout.flush()

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

What about using PRIOR,

so

SELECT id, parent_id, PRIOR name
   FROM tbl 
START WITH id = 1 
CONNECT BY PRIOR id = parent_id`

or if you want to get the root name

SELECT id, parent_id, CONNECT_BY_ROOT name
   FROM tbl 
START WITH id = 1 
CONNECT BY PRIOR id = parent_id

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

You can use a lambda expression, e.g:

sales['time_hour'] = sales.timestamp.apply(lambda x: x.hour)

SELECT  [ReportId], 
        SUBSTRING(d.EmailList,1, LEN(d.EmailList) - 1) EmailList
FROM
        (
            SELECT DISTINCT [ReportId]
            FROM Table1
        ) a
        CROSS APPLY
        (
            SELECT [Email] + ', ' 
            FROM Table1 AS B 
            WHERE A.[ReportId] = B.[ReportId]
            FOR XML PATH('')
        ) D (EmailList)

Btw you can also use the ui-sref attribute in your templates to pass objects

ui-sref="myState({ myParam: myObject })"

After running your local host you get http://localhost:[port number]/ here you found your port number.

Then get your IP address from Command, Open your windows command and type ipconfig

In my case, IP was 192.168.10.33 so my URL will be http://192.168.10.33:[port number]/. In Android, the studio uses this URL as your URL. And after that set your URL and your port number in manual proxy for the emulator.

Don't know if this will work for the situation given in the original post (never mind the fact that this is two years later), but this example works for me:

Hashtable htImageTypes = new Hashtable();
htImageTypes.Add("JPEG", "*.jpg");
htImageTypes.Add("GIF", "*.gif");
htImageTypes.Add("BMP", "*.bmp");

foreach (DictionaryEntry ImageType in htImageTypes)
{
    cmbImageType.Items.Add(ImageType);
}
cmbImageType.DisplayMember = "key";
cmbImageType.ValueMember = "value";

To read your value back out, you'll have to cast the SelectedItem property to a DictionaryEntry object, and you can then evaluate the Key and Value properties of that. For instance:

DictionaryEntry deImgType = (DictionaryEntry)cmbImageType.SelectedItem;
MessageBox.Show(deImgType.Key + ": " + deImgType.Value);

You can use the below query to identify the values. But please keep in mind that this will not give you the results from encrypted stored procedure.

SELECT DISTINCT OBJECT_NAME(comments.id) OBJECT_NAME
    ,objects.type_desc
FROM syscomments comments
    ,sys.objects objects
WHERE comments.id = objects.object_id
    AND TEXT LIKE '%CreatedDate%'
ORDER BY 1

The reason why Ng-Bind is better because,

When Your page is not Loaded or when your internet is slow or when your website loaded half, then you can see these type of issues (Check the Screen Shot with Read mark) will be triggered on Screen which is Completly weird. To avoid such we should use Ng-bind

Hope I'm not going offtopic on my first post, but I'd like to expand a little on the casting of integer to string as some respondents appear to have it wrong.

Because the expression in this query uses an arithmetic operator (the plus symbol +), MySQL will convert any strings in the expression to numbers.

To demonstrate, the following will produce the result 6:

SELECT ' 05.05 '+'.95';

String concatenation in MySQL requires the CONCAT() function so there is no ambiguity here and MySQL converts the strings to floats and adds them together.

I actually think the reason the initial query wasn't working is most likely because the $points variable was not in fact set to the user's current points. It was either set to zero, or was unset: MySQL will cast an empty string to zero. For illustration, the following will return 0:

SELECT ABS('');

Like I said, I hope I'm not being too off-topic. I agree that Daan and Tomas have the best solutions for this particular problem.

The easiest way is by using Oracle function:

SELECT REGEXP_COUNT(COLUMN_NAME,'CONDITION') FROM TABLE_NAME

http://site.mockito.org/mockito/docs/1.10.19/org/mockito/Matchers.html

anyObject() should fit your needs.

Also, you can always consider implementing hashCode() and equals() for the Bazoo class. This would make your code example work the way you want.

I simply declared as below in web.xml file and Its working for me :

 <welcome-file-list>
    <welcome-file>/WEB-INF/jsps/index.jsp</welcome-file>
</welcome-file-list>

And NO html/jsp pages present in public directory except static resources(css, js, images). Now I can access my index page with URL like : http://localhost:8080/app/ Its calling /WEB-INF/jsps/index.jsp page. When hosted live in production the final URL looks like https://eisdigital.com/

<?php $data = "<div><p>Welcome to my PHP class, we are glad you are here</p></div>"; echo strip_tags($data); ?>

Or if you have a content coming from the database;

<?php $data = strip_tags($get_row['description']); ?> <?=substr($data, 0, 100) ?><?php if(strlen($data) > 100) { ?>...<?php } ?>

On a table with 158k pseudo-random rows (usr_id uniformly distributed between 0 and 10k, trans_id uniformly distributed between 0 and 30),

By query cost, below, I am referring to Postgres' cost based optimizer's cost estimate (with Postgres' default xxx_cost values), which is a weighed function estimate of required I/O and CPU resources; you can obtain this by firing up PgAdminIII and running "Query/Explain (F7)" on the query with "Query/Explain options" set to "Analyze"

• Quassnoy's query has a cost estimate of 745k (!), and completes in 1.3 seconds (given a compound index on (usr_id, trans_id, time_stamp))
• Bill's query has a cost estimate of 93k, and completes in 2.9 seconds (given a compound index on (usr_id, trans_id))
• Query #1 below has a cost estimate of 16k, and completes in 800ms (given a compound index on (usr_id, trans_id, time_stamp))
• Query #2 below has a cost estimate of 14k, and completes in 800ms (given a compound function index on (usr_id, EXTRACT(EPOCH FROM time_stamp), trans_id))
  • this is Postgres-specific
• Query #3 below (Postgres 8.4+) has a cost estimate and completion time comparable to (or better than) query #2 (given a compound index on (usr_id, time_stamp, trans_id)); it has the advantage of scanning the lives table only once and, should you temporarily increase (if needed) work_mem to accommodate the sort in memory, it will be by far the fastest of all queries.

All times above include retrieval of the full 10k rows result-set.

Your goal is minimal cost estimate and minimal query execution time, with an emphasis on estimated cost. Query execution can dependent significantly on runtime conditions (e.g. whether relevant rows are already fully cached in memory or not), whereas the cost estimate is not. On the other hand, keep in mind that cost estimate is exactly that, an estimate.

The best query execution time is obtained when running on a dedicated database without load (e.g. playing with pgAdminIII on a development PC.) Query time will vary in production based on actual machine load/data access spread. When one query appears slightly faster (<20%) than the other but has a much higher cost, it will generally be wiser to choose the one with higher execution time but lower cost.

When you expect that there will be no competition for memory on your production machine at the time the query is run (e.g. the RDBMS cache and filesystem cache won't be thrashed by concurrent queries and/or filesystem activity) then the query time you obtained in standalone (e.g. pgAdminIII on a development PC) mode will be representative. If there is contention on the production system, query time will degrade proportionally to the estimated cost ratio, as the query with the lower cost does not rely as much on cache whereas the query with higher cost will revisit the same data over and over (triggering additional I/O in the absence of a stable cache), e.g.:

              cost | time (dedicated machine) |     time (under load) |
-------------------+--------------------------+-----------------------+
some query A:   5k | (all data cached)  900ms | (less i/o)     1000ms |
some query B:  50k | (all data cached)  900ms | (lots of i/o) 10000ms |

Do not forget to run ANALYZE lives once after creating the necessary indices.

Query #1

-- incrementally narrow down the result set via inner joins
--  the CBO may elect to perform one full index scan combined
--  with cascading index lookups, or as hash aggregates terminated
--  by one nested index lookup into lives - on my machine
--  the latter query plan was selected given my memory settings and
--  histogram
SELECT
  l1.*
 FROM
  lives AS l1
 INNER JOIN (
    SELECT
      usr_id,
      MAX(time_stamp) AS time_stamp_max
     FROM
      lives
     GROUP BY
      usr_id
  ) AS l2
 ON
  l1.usr_id     = l2.usr_id AND
  l1.time_stamp = l2.time_stamp_max
 INNER JOIN (
    SELECT
      usr_id,
      time_stamp,
      MAX(trans_id) AS trans_max
     FROM
      lives
     GROUP BY
      usr_id, time_stamp
  ) AS l3
 ON
  l1.usr_id     = l3.usr_id AND
  l1.time_stamp = l3.time_stamp AND
  l1.trans_id   = l3.trans_max

Query #2

-- cheat to obtain a max of the (time_stamp, trans_id) tuple in one pass
-- this results in a single table scan and one nested index lookup into lives,
--  by far the least I/O intensive operation even in case of great scarcity
--  of memory (least reliant on cache for the best performance)
SELECT
  l1.*
 FROM
  lives AS l1
 INNER JOIN (
   SELECT
     usr_id,
     MAX(ARRAY[EXTRACT(EPOCH FROM time_stamp),trans_id])
       AS compound_time_stamp
    FROM
     lives
    GROUP BY
     usr_id
  ) AS l2
ON
  l1.usr_id = l2.usr_id AND
  EXTRACT(EPOCH FROM l1.time_stamp) = l2.compound_time_stamp[1] AND
  l1.trans_id = l2.compound_time_stamp[2]

Finally, as of version 8.4, Postgres supports Window Function meaning you can write something as simple and efficient as:

Query #3

-- use Window Functions
-- performs a SINGLE scan of the table
SELECT DISTINCT ON (usr_id)
  last_value(time_stamp) OVER wnd,
  last_value(lives_remaining) OVER wnd,
  usr_id,
  last_value(trans_id) OVER wnd
 FROM lives
 WINDOW wnd AS (
   PARTITION BY usr_id ORDER BY time_stamp, trans_id
   ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
 );

Try using this code, it worked for me:

z-index: unset;

Why not just, a=a(~~a) or a(~a)=[]. It's equivalent to the other approaches but certainly less key strokes.

If your data is 'test', 'test0', 'test1111', '111test', '111'

To select all records where the data is a simple int:

SELECT * 
FROM myTable 
WHERE col1 REGEXP '^[0-9]+$';

Result: '111'

(In regex, ^ means begin, and $ means end)

To select all records where an integer or decimal number exists:

SELECT * 
FROM myTable 
WHERE col1 REGEXP '^[0-9]+\\.?[0-9]*$'; - for 123.12

Result: '111' (same as last example)

Finally, to select all records where number exists, use this:

SELECT * 
FROM myTable 
WHERE col1 REGEXP '[0-9]+';

Result: 'test0' and 'test1111' and '111test' and '111'

With kotlin and Gson we can do it more easily:

1. First, add Gson dependency:

implementation "com.squareup.retrofit2:converter-gson:2.3.0"

2. Create a separate kotlin file, add the following methods

import com.google.gson.Gson
import com.google.gson.reflect.TypeToken

fun <T> Gson.convertToJsonString(t: T): String {
    return toJson(t).toString()
}

fun <T> Gson.convertToModel(jsonString: String, cls: Class<T>): T? {
    return try {
        fromJson(jsonString, cls)
    } catch (e: Exception) {
        null
    }
}

inline fun <reified T> Gson.fromJson(json: String) = this.fromJson<T>(json, object: TypeToken<T>() {}.type)

Note: Do not add declare class, just add these methods, everything will work fine.

3. Now to call:

create a reference of gson:

val gson=Gson()

To convert array to json string, call:

val jsonString=gson.convertToJsonString(arrayList)

To get array from json string, call:

val arrayList=gson.fromJson<ArrayList<YourModelClassName>>(jsonString)

To convert a model to json string, call:

val jsonString=gson.convertToJsonString(model)

To convert json string to model, call:

val model=gson.convertToModel(jsonString, YourModelClassName::class.java)

You can do

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(o -> o.getField()).sum();

or (using Method reference)

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(Obj::getField).sum();

Trivial (but working) solution:

echo -e "---------------------------- [UP]\r$PROC_NAME "

Here is working code for converting an image from a base64 string to an Image object and storing it in a folder with unique file name:

public void SaveImage()
{
    string strm = "R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"; 

    //this is a simple white background image
    var myfilename= string.Format(@"{0}", Guid.NewGuid());

    //Generate unique filename
    string filepath= "~/UserImages/" + myfilename+ ".jpeg";
    var bytess = Convert.FromBase64String(strm);
    using (var imageFile = new FileStream(filepath, FileMode.Create))
    {
        imageFile.Write(bytess, 0, bytess.Length);
        imageFile.Flush();
    }
}

You can use JQuery Ajax and POST method:

var obj;

                
$(document).ready(function(){
            $("#button1").click(function(){
                var username=$("#username").val();
                var password=$("#password").val();
  $.ajax({
    url: "addperson.php",
    type: "POST", 
    async: false,
    data: {
        username: username,
        password: password
    }
})
.done (function(data, textStatus, jqXHR) { 
    
   obj = JSON.parse(data);
   
})
.fail (function(jqXHR, textStatus, errorThrown) { 
    
})
.always (function(jqXHROrData, textStatus, jqXHROrErrorThrown) { 
    
});
  
 
            });
        });

To take a response back from the php script JSON parse the the respone in .done() method. Here is the php script you can modify to your needs:

<?php
     $username1 = isset($_POST["username"]) ? $_POST["username"] : '';
    
     $password1 = isset($_POST["password"]) ? $_POST["password"] : '';

$servername = "xxxxx";
$username = "xxxxx";
$password = "xxxxx";
$dbname = "xxxxx";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO user (username, password)
VALUES ('$username1', '$password1' )";

    ;  
    
    
   

if ($conn->query($sql) === TRUE) {
    
   echo json_encode(array('success' => 1));
} else{
    
    
  echo json_encode(array('success' => 0));
}





$conn->close();
?>

The 2nd document quoted by Peter Mortensen in his comment on the answer of Codesmith made things much clearer for me. That document was written by windowsinspired.com. The link repeated: A Better Way To Understand Quoting and Escaping of Windows Command Line Arguments.

Some further trial and error leads to the following guideline:

Escape every double quote " with a caret ^. If you want other characters with special meaning to the Windows command shell (e.g., <, >, |, &) to be interpreted as regular characters instead, then escape them with a caret, too.

If you want your program foo to receive the command line text "a\"b c" > d and redirect its output to file out.txt, then start your program as follows from the Windows command shell:

foo ^"a\^"b c^" ^> d > out.txt

If foo interprets \" as a literal double quote and expects unescaped double quotes to delimit arguments that include whitespace, then foo interprets the command as specifying one argument a"b c, one argument >, and one argument d.

If instead foo interprets a doubled double quote "" as a literal double quote, then start your program as

foo ^"a^"^"b c^" ^> d > out.txt

The key insight from the quoted document is that, to the Windows command shell, an unescaped double quote triggers switching between two possible states.

Some further trial and error implies that in the initial state, redirection (to a file or pipe) is recognized and a caret ^ escapes a double quote and the caret is removed from the input. In the other state, redirection is not recognized and a caret does not escape a double quote and isn't removed. Let's refer to these states as 'outside' and 'inside', respectively.

If you want to redirect the output of your command, then the command shell must be in the outside state when it reaches the redirection, so there must be an even number of unescaped (by caret) double quotes preceding the redirection. foo "a\"b " > out.txt won't work -- the command shell passes the entire "a\"b " > out.txt to foo as its combined command line arguments, instead of passing only "a\"b " and redirecting the output to out.txt.

foo "a\^"b " > out.txt won't work, either, because the caret ^ is encountered in the inside state where it is an ordinary character and not an escape character, so "a\^"b " > out.txt gets passed to foo.

The only way that (hopefully) always works is to keep the command shell always in the outside state, because then redirection works.

If you don't need redirection (or other characters with special meaning to the command shell), then you can do without the carets. If foo interprets \" as a literal double quote, then you can call it as

foo "a\"b c"

Then foo receives "a\"b c" as its combined arguments text and can interpret it as a single argument equal to a"b c.

Now -- finally -- to the original question. myscript '"test"' called from the Windows command shell passes '"test"' to myscript. Apparently myscript interprets the single and double quotes as argument delimiters and removes them. You need to figure out what myscript accepts as a literal double quote and then specify that in your command, using ^ to escape any characters that have special meaning to the Windows command shell. Given that myscript is also available on Unix, perhaps \" does the trick. Try

myscript \^"test\^"

or, if you don't need redirection,

myscript \"test\"

First check the $_GET['s'] is set or not. Change your conditions like this

<?php
if (isset($_GET['s']) && $_GET['s'] == 'jwshxnsyllabus')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml',         '../bibliographies/jwshxnbibliography_')\">";
elseif (isset($_GET['s']) && $_GET['s'] == 'aquinas')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">"; 
elseif (isset($_GET['s']) && $_GET['s'] == 'POP2')
echo "<body onload=\"loadSyllabi('POP2')\">";
elseif (isset($_GET['s']) && $_GET['s'] == null)
echo "<body>"
?>

And also handle properly your ifelse conditions

Word of caution when coding with Visual Studio (2013)

I have wasted 4 to 5 hours trying to debug this error. I tried all the solutions that I found on StackOverflow by the letter and I still got this error: Can't bind to 'routerlink' since it isn't a known native property

Be aware, Visual Studio has the nasty habit of autoformatting text when you copy/paste code. I always got a small instantaneous adjustment from VS13 (camel case disappears).

This:

<div>
    <a [routerLink]="['/catalog']">Catalog</a>
    <a [routerLink]="['/summary']">Summary</a>
</div>

Becomes:

<div>
    <a [routerlink]="['/catalog']">Catalog</a>
    <a [routerlink]="['/summary']">Summary</a>
</div>

It's a small difference, but enough to trigger the error. The ugliest part is that this small difference just kept avoiding my attention every time I copied and pasted. By sheer chance, I saw this small difference and solved it.

String a = new String("foo");
String b = new String("foo");
System.out.println(a == b); // prints false
System.out.println(a.equals(b)); // prints true

Make sure you understand why. It's because the == comparison only compares references; the equals() method does a character-by-character comparison of the contents.

When you call new for a and b, each one gets a new reference that points to the "foo" in the string table. The references are different, but the content is the same.

mime_content_type() is deprecated, so you won't be able to count on it working in the future. There is a "fileinfo" PECL extension, but I haven't heard good things about it.

If you are running on a *nix server, you can do the following, which has worked fine for me:

$file = escapeshellarg( $filename );
$mime = shell_exec("file -bi " . $file);
$filename should probably include the absolute path.

I also had a similar error log and here's what I did-

1. In onCreate method we request a Dialog Box for checking permissions

   ActivityCompat.requestPermissions(MainActivity.this,
   new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},1);
   

2. Method to check for the result

   @Override
   public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
   switch (requestCode) {
       case 1: {
           // If request is cancelled, the result arrays are empty.
           if (grantResults.length > 0
                   && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
               // permission granted and now can proceed
            mymethod(); //a sample method called
   
           } else {
   
               // permission denied, boo! Disable the
               // functionality that depends on this permission.
               Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
           }
           return;
       }
       // add other cases for more permissions
       }
   }
   

The official documentation to Requesting Runtime Permissions

I suppose you want to commit the changes to one branch and then make those changes visible in the other branch. In git you should have no changes on top of HEAD when changing branches.

You commit only the changed files by:

git commit [some files]

Or if you are sure that you have a clean staging area you can

git add [some files]       # add [some files] to staging area
git add [some more files]  # add [some more files] to staging area
git commit                 # commit [some files] and [some more files]

If you want to make that commit available on both branches you do

git stash                     # remove all changes from HEAD and save them somewhere else
git checkout <other-project>  # change branches
git cherry-pick <commit-id>   # pick a commit from ANY branch and apply it to the current
git checkout <first-project>  # change to the other branch
git stash pop                 # restore all changes again

Since you are looking for adding space between elements you may need something as simple as a margin-left or padding-left. Here are examples of both http://jsfiddle.net/BGHqn/3/

This will add 10 pixels to the left of the paragraph element

p {
    margin-left: 10px;
 }

or if you just want some padding within your paragraph element

p {
    padding-left: 10px;
}

An easy approach would be making all the blank cells NA and only keeping complete cases. You might also look for na.omit examples. It is a widely discussed topic.

df[df==""]<-NA
df<-df[complete.cases(df),]

If You are a newbie then you can take reference from my code .. what i did was to put on a check so that i could only get the Alphabets and white spaces! You can Repeat the for loop after the second if statement to validate the string again

       bool check = false;

       Console.WriteLine("Please Enter the Name");
       name=Console.ReadLine();

       for (int i = 0; i < name.Length; i++)
       {
           if (name[i]>='a' && name[i]<='z' || name[i]==' ')
           {
               check = true;
           }
           else
           {
               check = false;
               break;
           }

       }

       if (check==false)
       {
           Console.WriteLine("Enter Valid Value");
           name = Console.ReadLine();
       }

This is a work around.

iOS5 has support for this (Reference). If you want to invoke the native date picker you might have a an option with PhoneGap (have not tested this myself).

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

I had same issue. Resolved by firstly setting :

imageView.setMinHeight(0);
imageView.setMinimumHeight(0);

And then :

imageView.getLayoutParams().height= ViewGroup.LayoutParams.MATCH_PARENT;

setMinHeight is defined by ImageView, while setMinimumHeight is defined by View. According to the docs, the greater of the two values is used, so both must be set.

Prepare to have your mind-blown.

Cheers!

For over-full-screen or over-context modal presentation, "is visible" could mean it is on top of the view controller stack or just visible but covered by another view controller.

To check if the view controller "is the top view controller" is quite different from "is visible", you should check the view controller's navigation controller's view controller stack.

I wrote a piece of code to solve this problem:

extension UIViewController {
    public var isVisible: Bool {
        if isViewLoaded {
            return view.window != nil
        }
        return false
    }

    public var isTopViewController: Bool {
        if self.navigationController != nil {
            return self.navigationController?.visibleViewController === self
        } else if self.tabBarController != nil {
            return self.tabBarController?.selectedViewController == self && self.presentedViewController == nil
        } else {
            return self.presentedViewController == nil && self.isVisible
        }
    }
}

Wanted to add my experience with converting. I had many text fields in ancient Linq2SQL code. This was to allow text columns present in indexes to be rebuilt ONLINE.

First I've known about the benefits for years, but always assumed that converting would mean some scary long queries where SQL Server would have to rebuild the table and copy everything over, bringing down my websites and raising my heartrate.

I was also concerned that the Linq2SQL could cause errors if it was doing some kind of verification of the column type.

Happy to report though, that the ALTER commands returned INSTANTLY - so they are definitely only changing table metadata. There may be some offline work happening to bring <8000 character data back to be in-table, but the ALTER command was instant.

I ran the following to find all columns needing conversion:

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] VARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'TEXT' order by table_name, column_name

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] NVARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'NTEXT' order by table_name, column_name

This gave me a nice list of queries, which I just selected and copied to a new window. Like I said - running this was instant.

Linq2SQL is pretty ancient - it uses a designer that you drag tables onto. The situation may be more complex for EF Code first but I haven't tackled that yet.

With SpringBoot 2 Spring Security, The code below perfectly resolved Cors issues

@Bean
public CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Collections.singletonList("*")); // <-- you may change "*"
    configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "POST", "PUT", "DELETE", "PATCH"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedHeaders(Arrays.asList(
            "Accept", "Origin", "Content-Type", "Depth", "User-Agent", "If-Modified-Since,",
            "Cache-Control", "Authorization", "X-Req", "X-File-Size", "X-Requested-With", "X-File-Name"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

@Bean
public FilterRegistrationBean<CorsFilter> corsFilterRegistrationBean() {
    FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<>(new CorsFilter(corsConfigurationSource()));
    bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return bean;
}

Then for the WebSecurity Configuration, I added this

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.headers().frameOptions().disable()
            .and()
            .authorizeRequests()
            .antMatchers("/oauth/tokeen").permitAll()
            .antMatchers(HttpMethod.GET, "/").permitAll()
            .antMatchers(HttpMethod.POST, "/").permitAll()
            .antMatchers(HttpMethod.PUT, "/").permitAll()
            .antMatchers(HttpMethod.DELETE, "/**").permitAll()
            .antMatchers(HttpMethod.OPTIONS, "*").permitAll()
            .anyRequest().authenticated()
            .and().cors().configurationSource(corsConfigurationSource());
}

I use an easier regex pattern

^[0-9A-Fa-f\-]{36}$

This is useful in contexts where the encoding is not told per HTTP header or other meta data, e.g. the local file system.

Imagine the following stylesheet:

[rel="external"]::after
{
    content: ' ?';
}

If a reader saves the file to a hard drive and you omit the @charset rule, most browsers will read it in the OS’ locale encoding, e.g. Windows-1252, and insert ↗ instead of an arrow.

Unfortunately, you cannot rely on this mechanism as the support is rather … rare. And remember that on the net an HTTP header will always override the @charset rule.

The correct rules to determine the character set of a stylesheet are in order of priority:

1. HTTP Charset header.
2. Byte Order Mark.
3. The first @charset rule.
4. UTF-8.

The last rule is the weakest, it will fail in some browsers.
The charset attribute in <link rel='stylesheet' charset='utf-8'> is obsolete in HTML 5.
Watch out for conflict between the different declarations. They are not easy to debug.

Recommended reading

• Russ Rolfe: Declaring character encodings in CSS
• IANA: Official names for character sets – other names are not allowed; use the preferred name for @charset if more than one name is registered for the same encoding.
• MDN: @charset. There is a support table. I do not trust this. :)

For me the following worked:

1. Kill adb.exe from Task Manager

2. Restart Eclipse as administrator

3. For my app, the target was Google APIs level 10.. I went to Window-> AVD Manager and the entry for "Google APIs level 10" had a broken instead of a green tick - so I just clicked the entry and clicked the "repair" button and problem was fixed

(It was probably only 3 above..)

The easy way and fast way to do this is:

three = [sum(i) for i in zip(first,second)] # [7,9,11,13,15]

Alternatively, you can use numpy sum:

from numpy import sum
three = sum([first,second], axis=0) # array([7,9,11,13,15])

Try using setAttribute instead:

document.getElementById('img')
    .setAttribute(
        'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
    );

Real answer: (And make sure you remove the line-breaks in the base64.)
