Like this.

.divContainer input[type="text"] {
  width:150px;
}
.divContainer input[type="radio"] {
  width:20px;
}

In this particular case, a viewModel is required to launch the task and notify the view upon its completion. An "async property", not an "async constructor", is in order.

I just released AsyncMVVM, which solves exactly this problem (among others). Should you use it, your ViewModel would become:

public class ViewModel : AsyncBindableBase
{
    public ObservableCollection<TData> Data
    {
        get { return Property.Get(GetDataAsync); }
    }

    private Task<ObservableCollection<TData>> GetDataAsync()
    {
        //Get the data asynchronously
    }
}

Strangely enough, Silverlight is supported. :)

You have to add the following dependency to your build:

<dependency>
    <groupId>org.openrdf.sesame</groupId>
    <artifactId>sesame-rio-api</artifactId>
    <version>2.7.2</version>
</dependency>

Furthermore i would suggest to take a deep look into the documentation about how to use the lib.

String str = "saveMe"
compareString(str)

def compareString(String str){
  def str2 = "saveMe"

  // using single quotes
  println 'single quote string class' + 'String.class'.class
  println str + ' == ' + str2 + " ? " + (str == str2)
  println ' str = ' +  '$str' //  interpolation not supported

  // using double quotes, Interpolation supported
  println "double quoted string with interpolation " + "GString.class $str".class
  println "double quoted string without interpolation " + "String.class".class
  println "$str equals $str2 ? " + str.equals(str2) 
  println '$str == $str2 ? ' + "$str==$str2"
  println '${str == str2} ? ' + "${str==str2} ? "

  println '$str equalsIgnoreCase $str2 ? ' + str.equalsIgnoreCase(str2)   

  println '''

If you want headless browser support then there is another approach you might adopt.

https://github.com/detro/ghostdriver

It was announced during Selenium Conference and it is still in development. It uses PhantomJS as the browser and is much better than HTMLUnitDriver, there are no screenshots yet, but as it is still in active development.

If you run winsdk_web.exe from the following link, you can selectively install windbg or extract windbg installer msi.

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

If you need to create each ArrayList item in a single line then you can use this code

private void createFile(String file, ArrayList<String> arrData)
            throws IOException {
        FileWriter writer = new FileWriter(file + ".txt");
        int size = arrData.size();
        for (int i=0;i<size;i++) {
            String str = arrData.get(i).toString();
            writer.write(str);
            if(i < size-1)**//This prevent creating a blank like at the end of the file**
                writer.write("\n");
        }
        writer.close();
    }

You are trying to access the struct statically with a . instead of ::, nor are its members static. Either instantiate ReducedForm:

ReducedForm rf;
rf.iSimplifiedNumerator = 5;

or change the members to static like this:

struct ReducedForm
{
    static int iSimplifiedNumerator;
    static int iSimplifiedDenominator;
};

In the latter case, you must access the members with :: instead of . I highly doubt however that the latter is what you are going for ;)

You could use the :first-child and :last-child pseudo-selectors:

tr td:first-child,
tr td:last-child {
    /* styles */
}

This should work in all major browsers, but IE7 has some problems when elements are added dynamically (and it won't work in IE6).

Actually, when you use git reset, you should refer to the commit that you are resetting to; so you would want the db0c078 commit, probably.

An easier version would be git reset --hard HEAD^, to reset to the previous commit before the current head; that way you don't have to be copying around commit IDs.

Beware when you do any git reset --hard, as you can lose any uncommitted changes you have. You might want to check git status to make sure your working copy is clean, or that you do want to blow away any changes that are there.

In addition, instead of HEAD you can use origin/master as reference, as suggested by @bdonlan in the comments: git reset --hard origin/master

I think that the most basic way to call methods is by setting a request on the child component. Then as soon as the child handles the request, it calls a callback method to reset the request.

The reset mechanism is necessary to be able to send the same request multiple times after each other.

In parent component

In the render method of the parent:

const { request } = this.state;
return (<Child request={request} onRequestHandled={()->resetRequest()}/>);

The parent needs 2 methods, to communicate with its child in 2 directions.

sendRequest() {
  const request = { param: "value" };
  this.setState({ request });
}

resetRequest() {
  const request = null;
  this.setState({ request });
}

In child component

The child updates its internal state, copying the request from the props.

constructor(props) {
  super(props);
  const { request } = props;
  this.state = { request };
}

static getDerivedStateFromProps(props, state) {
  const { request } = props;
  if (request !== state.request ) return { request };
  return null;
}

Then finally it handles the request, and sends the reset to the parent:

componentDidMount() {
  const { request } = this.state;
  // todo handle request.

  const { onRequestHandled } = this.props;
  if (onRequestHandled != null) onRequestHandled();
}

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

This one was perfect for me. Keeps aspect ratio and takes a maxLength. Width or Height will not be more than maxLength

-(UIImage*)imageWithImage: (UIImage*) sourceImage maxLength: (float) maxLength
{
    CGFloat scaleFactor = maxLength / MAX(sourceImage.size.width, sourceImage.size.height);

    float newHeight = sourceImage.size.height * scaleFactor;
    float newWidth = sourceImage.size.width * scaleFactor;

    UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));
    [sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}

I use a percentage method to achieve

        border: 3px solid rgb(1, 1, 1);
        border-top-left-radius: 100% 200%;
        border-top-right-radius: 100% 200%;

I think it's a better way to bind on the service itself instead of the attributes on it.

Here's why:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.7/angular.min.js"></script>
<body ng-app="BindToService">

  <div ng-controller="BindToServiceCtrl as ctrl">
    ArrService.arrOne: <span ng-repeat="v in ArrService.arrOne">{{v}}</span>
    <br />
    ArrService.arrTwo: <span ng-repeat="v in ArrService.arrTwo">{{v}}</span>
    <br />
    <br />
    <!-- This is empty since $scope.arrOne never changes -->
    arrOne: <span ng-repeat="v in arrOne">{{v}}</span>
    <br />
    <!-- This is not empty since $scope.arrTwo === ArrService.arrTwo -->
    <!-- Both of them point the memory space modified by the `push` function below -->
    arrTwo: <span ng-repeat="v in arrTwo">{{v}}</span>
  </div>

  <script type="text/javascript">
    var app = angular.module("BindToService", []);

    app.controller("BindToServiceCtrl", function ($scope, ArrService) {
      $scope.ArrService = ArrService;
      $scope.arrOne = ArrService.arrOne;
      $scope.arrTwo = ArrService.arrTwo;
    });

    app.service("ArrService", function ($interval) {
      var that = this,
          i = 0;
      this.arrOne = [];
      that.arrTwo = [];

      $interval(function () {
        // This will change arrOne (the pointer).
        // However, $scope.arrOne is still same as the original arrOne.
        that.arrOne = that.arrOne.concat([i]);

        // This line changes the memory block pointed by arrTwo.
        // And arrTwo (the pointer) itself never changes.
        that.arrTwo.push(i);
        i += 1;
      }, 1000);

    });
  </script>
</body> 

You can play it on this plunker.

Edit

This edit improves and explains the answer based on the comments.

var search = location.search.substring(1);
JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')

Example

Parse abc=foo&def=%5Basf%5D&xyz=5 in five steps:

• decodeURI: abc=foo&def=[asf]&xyz=5
• Escape quotes: same, as there are no quotes
• Replace &: abc=foo","def=[asf]","xyz=5
• Replace =: abc":"foo","def":"[asf]","xyz":"5
• Suround with curlies and quotes: {"abc":"foo","def":"[asf]","xyz":"5"}

which is legal JSON.

An improved solution allows for more characters in the search string. It uses a reviver function for URI decoding:

var search = location.search.substring(1);
JSON.parse('{"' + search.replace(/&/g, '","').replace(/=/g,'":"') + '"}', function(key, value) { return key===""?value:decodeURIComponent(value) })

Example

search = "abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar";

gives

Object {abc: "foo", def: "[asf]", xyz: "5", foo: "b=ar"}

Original answer

A one-liner:

JSON.parse('{"' + decodeURI("abc=foo&def=%5Basf%5D&xyz=5".replace(/&/g, "\",\"").replace(/=/g,"\":\"")) + '"}')

Assuming that your table is called 'Table1' and the column you need is 'Column' you can try this:

for i = 1 to Range("Table1").Rows.Count
   Range("Table1[Column]")(i)="PHEV"
next i

Security Warning: This class is not secure. It's using Rijndael256-ECB, which is not semantically secure. Just because "it works" doesn't mean "it's secure". Also, it strips tailing spaces afterwards due to not using proper padding.

Found this class recently, it works like a dream!

class Encryption {
    var $skey = "yourSecretKey"; // you can change it

    public  function safe_b64encode($string) {
        $data = base64_encode($string);
        $data = str_replace(array('+','/','='),array('-','_',''),$data);
        return $data;
    }

    public function safe_b64decode($string) {
        $data = str_replace(array('-','_'),array('+','/'),$string);
        $mod4 = strlen($data) % 4;
        if ($mod4) {
            $data .= substr('====', $mod4);
        }
        return base64_decode($data);
    }

    public  function encode($value){ 
        if(!$value){return false;}
        $text = $value;
        $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
        $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
        $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $this->skey, $text, MCRYPT_MODE_ECB, $iv);
        return trim($this->safe_b64encode($crypttext)); 
    }

    public function decode($value){
        if(!$value){return false;}
        $crypttext = $this->safe_b64decode($value); 
        $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
        $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
        $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $this->skey, $crypttext, MCRYPT_MODE_ECB, $iv);
        return trim($decrypttext);
    }
}

And to call it:

$str = "My secret String";

$converter = new Encryption;
$encoded = $converter->encode($str );
$decoded = $converter->decode($encoded);    

echo "$encoded<p>$decoded";

Use ArrayList.set

list.set(2, "New");

I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:

String cannot be resolved to a variable

With this Java code:

if (true)
    String my_variable = "somevalue";
    System.out.println("foobar");

You would think this code is very straight forward, the conditional is true, we set my_variable to somevalue. And it should print foobar. Right?

Wrong, you get the above mentioned compile time error. Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement.

If you put braces around the conditional block like this:

if (true){
    String my_variable = "somevalue"; }
    System.out.println("foobar");

Then it compiles and runs fine. Apparently poorly bracketed conditionals are fair game for generating compile time errors now.

document.getElementById("idframe").contentWindow.document.getElementById("idelement").value;

The best and most accurate method I found was to download the bfg.jar file: https://rtyley.github.io/bfg-repo-cleaner/

Then run the commands:

git clone --bare https://project/repository project-repository
cd project-repository
java -jar bfg.jar --delete-folders DIRECTORY_NAME
git reflog expire --expire=now --all && git gc --prune=now --aggressive
git push --mirror https://project/new-repository

If you want to delete files then use the delete-files option instead:

java -jar bfg.jar --delete-files *.pyc

just add them within the main bracket of the if statement like

if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) {
            PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}

Logically this can be rewritten in a better way too! This has exactly the same meaning

if (Type == 2 && (PageCount == 0 || PageCount == '')) {

Sounds bad?

 pkill `pidof myprocess`

example:

# kill all java processes
pkill `pidof java`

Newlines in HTML are expressed through <br>, not through \n.

Using \n in PHP creates a newline in the source code, and HTML source code layout is unconnected to HTML screen layout.

Lattice solution with additional settings which I needed:

library(lattice)
distribution<-function(x) {2^(-x*2)}
X<-seq(0,10,0.00001)
xyplot(distribution(X)~X,type="l", col = rgb(red = 255, green = 90, blue = 0, maxColorValue = 255), cex.lab = 3.5, cex.axis = 3.5, lwd=2 )

1. If you need your range of values for x plotted in increments different from 1, e.g. 0.00001 you can use:

X<-seq(0,10,0.00001)

2. You can change the colour of your line by defining a rgb value:

col = rgb(red = 255, green = 90, blue = 0, maxColorValue = 255)

3. You can change the width of the plotted line by setting:

lwd = 2

4. You can change the size of the labels by scaling them:

cex.lab = 3.5, cex.axis = 3.5

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

I know this is a done and sorted out deal, but here's what I'm using to solve the problem in my app.

if (!e.target.hasAttribute("target")) {
    e.preventDefault();     
    e.target.setAttribute("target", "_blank");
    e.target.click();
    return;
}

Basically what is going on here is I run a check for if the link has target=_blank attribute. If it doesn't, it stops the link from triggering, sets it up to open in a new window then programmatically clicks on it.

You can go one step further and skip the stopping of the original click (and make your code a whole lot more compact) by trying this:

if (!e.target.hasAttribute("target")) {
    e.target.setAttribute("target", "_blank");
}

If you were using jQuery to abstract away the implementation of adding an attribute cross-browser, you should use this instead of e.target.setAttribute("target", "_blank"):

    jQuery(event.target).attr("target", "_blank")

You may need to rework it to fit your exact use-case, but here's how I scratched my own itch.

Here's a demo of it in action for you to mess with.

(The link in jsfiddle comes back to this discussion .. no need a new tab :))

Get a reference to your input box however you like (eg document.getElementById('mytextbox')) and set its readonly property to true:

myInputBox.readonly = true;

Alternatively you can simply add this property inline (no JavaScript needed):

<input type="text" value="from db" readonly="readonly" />

If you just need a number that's bigger than all others, you can use

float('inf')

in similar fashion, a number smaller than all others:

float('-inf')

This works in both python 2 and 3.

Swift 3 or 4

let base64Encoded = Data("original string".utf8).base64EncodedString()

If all those kill process commands don't work for you, my suggestion is to check if you were using any other packages to run your node process.

I had the similar issue, and it was due to I was running my node process using PM2(a NPM package). The kill [processID] command disables the process but keeps the port occupied. Hence I had to go into PM2 and dump all node process to free up the port again.

To change tab settings, click the text area right to the Ln/Col text in the status bar on the bottom right of vscode window.

The name can be Tab Size or Spaces.

A menu will pop up with all available actions and settings.

With jQuery, the actual DOM element is at index zero, this should work

$('#a')[0].className = $('#a')[0].className.replace(/\bbg.*?\b/g, '');

function curPageName() {
 return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
echo "The current page is ".curPageName()."?".$_SERVER['QUERY_STRING'];

This will get you page name , it will get the string after the last slash

The following does what you need (I did my best, with loads of google searches along the way):

<html>
<head>
  <script>
    // no jquery, or other craziness. just
    // straight up vanilla javascript functions
    // to scroll a div's content to the bottom
    // if the user has not scrolled up.  Includes
    // a clickable "alert" for when "content" is
    // changed.

    // this should work for any kind of content
    // be it images, or links, or plain text
    // simply "append" the new element to the
    // div, and this will handle the rest as
    // proscribed.

    let scrolled = false; // at bottom?
    let scrolling = false; // scrolling in next msg?
    let listener = false; // does element have content changed listener?
    let contentChanged = false; // kind of obvious
    let alerted = false; // less obvious

    function innerHTMLChanged() {
      // this is here in case we want to
      // customize what goes on in here.
      // for now, just:
      contentChanged = true;
    }

    function scrollToBottom(id) {
      if (!id) { id = "scrollable_element"; }
      let DEBUG = 0; // change to 1 and open console
      let dstr = "";

      let e = document.getElementById(id);
      if (e) {
        if (!listener) {
          dstr += "content changed listener not active\n";
          e.addEventListener("DOMSubtreeModified", innerHTMLChanged);
          listener = true;
        } else {
          dstr += "content changed listener active\n";
        }
        let height = (e.scrollHeight - e.offsetHeight); // this isn't perfect
        let offset = (e.offsetHeight - e.clientHeight); // and does this fix it? seems to...
        let scrollMax = height + offset;

        dstr += "offsetHeight: " + e.offsetHeight + "\n";
        dstr += "clientHeight: " + e.clientHeight + "\n";
        dstr += "scrollHeight: " + e.scrollHeight + "\n";
        dstr += "scrollTop: " + e.scrollTop + "\n";

        dstr += "offset: " + offset + "\n";
        dstr += "height: " + height + "\n";
        dstr += "contentChanged: " + contentChanged + "\n";

        if (!scrolled && !scrolling) {
          dstr += "user has not scrolled\n";
          if (e.scrollTop != scrollMax) {
            dstr += "scroll not at bottom\n";
            e.scroll({
              top: scrollMax,
              left: 0,
              behavior: "auto"
            })
            e.scrollTop = scrollMax;
            scrolling = true;
          } else {
            if (alerted) {
              dstr += "alert exists\n";
            } else {
              dstr += "alert does not exist\n";
            }
            if (contentChanged) { contentChanged = false; }
          }
        } else {
          dstr += "user scrolled away from bottom\n";
          if (!scrolling) {
            dstr += "not auto-scrolling\n";

            if (e.scrollTop >= scrollMax) {

Note: You may have to adjust the alert position (nposx and nposy) in both scrollToBottom and scrollMessages to match your needs...

And a link to my own working example, hosted on my server: https://night-stand.ca/jaretts_tests/chat_scroll.html

This means you are mapping a column twice in your entity class. Explaining with an example...

    @Column(name = "column1")
    private String object1;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "column1", referencedColumnName = "column1")
    private TableClass object2;

The problem in the above code snippet is we are repeating mapping...

Solution

Since mapping is an important part, you don't want to remove that. Instead, you will remove

    @Column(name = "column1")
    private String uniqueId;

You can still pass the value of object1 by creating a object of TableClass and assign the String value of Object1 in it.

This works 100%. I have tested this with Postgres and Oracle database.

for verilog just do

parameter ROWBITS = 4;
reg [ROWBITS-1:0] temp;
always @(posedge sysclk) begin
  temp <= {ROWBITS{1'b0}}; // fill with 0
end

You are close, but the parameter you pass to SecureStringToBSTR must be a SecureString. You appear to be passing the result of ConvertFrom-SecureString, which is an encrypted standard string. So call ConvertTo-SecureString on this before passing to SecureStringToBSTR.

$SecurePassword = ConvertTo-SecureString $PlainPassword -AsPlainText -Force
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecurePassword)
$UnsecurePassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)

MySQL date format is this : Y-M-D. You are using Y/M/D. That's is wrong. modify your query.

If you insert the date like Y/M/D, It will be insert null value in the database.

If you are using PHP and date you are getting from the form is like this Y/M/D, you can replace this with using the statement .

out_date=date('Y-m-d', strtotime(str_replace('/', '-', $data["input_date"])))

First find the condition that occurs in all situations, then filter the special conditions:

$('[myc="blue"]')
    .filter('[myid="1"],[myid="3"]');

for something that offers more performance than ''.format(), you can use this:

>>> ':'.join( '%02x'%(v if type(v) is int else ord(v)) for v in 'Hello World !!' )
'48:65:6C:6C:6F:20:77:6F:72:6C:64:20:21:21'
>>> 
>>> ':'.join( '%02x'%(v if type(v) is int else ord(v)) for v in b'Hello World !!' )
'48:65:6C:6C:6F:20:77:6F:72:6C:64:20:21:21'
>>> 

sorry this couldn't look nicer
would be nice if one could simply do '%02x'%v, but that only takes int...
but you'll be stuck with byte-strings b'' without the logic to select ord(v).

My stringdata is coming from PHP file but still, I indicate here in var. When i directly take my json into obj it will nothing show thats why i put my json file as

var obj=JSON.parse(stringdata); so after that i get message obj and show in alert box then I get data which is json array and store in one varible ArrObj then i read first object of that array with key value like this ArrObj[0].id

     var stringdata={
        "success": true,
        "message": "working",
        "data": [{
                  "id": 1,
                  "name": "foo"
         }]
      };

                var obj=JSON.parse(stringdata);
                var key = "message";
                alert(obj[key]);
                var keyobj = "data";
                var ArrObj =obj[keyobj];

                alert(ArrObj[0].id);

I had a similar problem but I fixed it with by doing some changes in firewall setting.

You can follow the below steps

1. Go to "Start" --> "Control Panel"

2. Click on "Windows Firewall"

3. Inside Windows Firewall, click on "Allow a program or feature through Windows Firewall"

4. Now inside of Allow Programs, Click on "Change Settings" button. Once you clicked on Change Settings button, the "Allow another program..." button gets enabled.

5. Click on "Allow another program..." button , a new dialog box will be opened. Choose the programs or application for which you are getting the socket exception and click on "Add" button.

6. Click OK, and restart your machine.

7. Try to run your application (which has an exception) with administrative rights.

I hope this helps.

There is a plugin, adampietrasiak/jquery.initialize, which is based on MutationObserver that achieves this simply.

$.initialize(".some-element", function() {
    $(this).css("color", "blue");
});

No, there isn't. New-expression only allows default initialization or no initialization at all.

The workaround would be to allocate raw memory buffer using operator new[] and then construct objects in that buffer using placement-new with non-default constructor.

I know it's a bit old question but still people try to find efficient solution so instead you should use FULLTEXT index (it's available from MySQL 5.6.4).

Query on table with +35mil records by triple like in where block took ~2.5s but after adding index on these fields and using BOOLEAN MODE inside match ... against ... it took only 0.05s.

Yes, indeed you need to have one child inside your <TouchableHighlight>.

And, If you don't want to pollute your file with Views you can use React Fragments to achieve the same.

<TouchableWithoutFeedback>
  <React.Fragment>
   ...
  </React.Fragment>
</TouchableWithoutFeedback>

or even better there is a short syntax for React Fragments. So the above code can be written as below:

<TouchableWithoutFeedback>
  <>
   ...
  </>
</TouchableWithoutFeedback>

Perm Gen stands for permanent generation which holds the meta-data information about the classes.

1. Suppose if you create a class name A, it's instance variable will be stored in heap memory and class A along with static classloaders will be stored in permanent generation.
2. Garbage collectors will find it difficult to clear or free the memory space stored in permanent generation memory. Hence it is always recommended to keep the permgen memory settings to the advisable limit.
3. JAVA8 has introduced the concept called meta-space generation, hence permgen is no longer needed when you use jdk 1.8 versions.

I didn't read all the posts but every answer seems to be missing one concept that really helped me "get it"...

If a Model is akin to a database Table, then a ViewModel is akin to a database View - A view typically either returns small amounts of data from one table, or, complex sets of data from multiple tables (joins).

I find myself using ViewModels to pass info into a view/form, and then transfering that data into a valid Model when the form posts back to the controller - also very handy for storing Lists(IEnumerable).

You may use PopupController for the same one the SDK which shows UIViewController as subview You may check PopupController

Here is sample code for the same

popup = PopupController
        .create(self.navigationController!)
        .customize(
            [
                .layout(.center),
                .animation(.fadeIn),
                .backgroundStyle(.blackFilter(alpha: 0.8)),
                .dismissWhenTaps(true),
                .scrollable(true)
            ]
        )
        .didShowHandler { popup in
        }
        .didCloseHandler { popup in
    }
    let container = MTMPlayerAndCardSelectionVC.instance()
    container.closeHandler = {() in
        self.popup.dismiss()
    }

    popup.show(container)

Did you try this in your routes.php ?

Route::group(['middleware' => ['web']], function () {
    //
    Route::get('/','HomeController@index');
});

use $BASHPID or $$

See the [manual][1] for more information, including differences between the two.

TL;DRTFM

• $$ Expands to the process ID of the shell.
  • In a () subshell, it expands to the process ID of the invoking shell, not the subshell.
• $BASHPID Expands to the process ID of the current Bash process (new to bash 4).
  • In a () subshell, it expands to the process ID of the subshell [1]: http://www.gnu.org/software/bash/manual/bashref.html#Bash-Variables

This works for me:

class MyClass {
    static MyEnum: { Value1; Value2; Value3; }
    = {
        Value1: "Value1",
        Value2: "Value2",
        Value3: "Value3"
    };
}

or

module MyModule {
    export var MyEnum: { Value1; Value2; Value3; }
    = {
        Value1: "Value1",
        Value2: "Value2",
        Value3: "Value3"
    };
}

8)

Update: Shortly after posting this I discovered another way, but forgot to post an update (however, someone already did mentioned it above):

enum MyEnum {
    value1 = <any>"value1 ", 
    value2 = <any>"value2 ", 
    value3 = <any>"value3 " 
}

To elaborate on Breno's answer... For Windows 7 these steps worked for me:

1. Open the Control Panel (Click the Start button, then click Control Panel)
2. Click User Accounts
3. Click Change my environment variables
4. Select PATH and click the Edit... button
5. At the end of the Variable value, add ;C:\Program Files\nodejs
6. Click Ok on the "Edit User Variable" window, then click Ok on the "Environment Variables" window
7. Start a command prompt window (Start button, then type cmd into the search and hit enter)
8. At the prompt (C:\>) type npm and hit enter; you should now see some help text (Usage: npm <command> etc.) rather than "npm is not recognized..."

Now you can start using npm!

NSString *string = [NSString stringWithFormat:@"%d", theinteger];

For the case you do not use "DO": this is my solution for a FOR EACH with nested If conditional statements:

For Each line In lines
    If <1st condition> Then
        <code if 1st condition>
        If <2nd condition> Then
            If <3rd condition> Then
                GoTo ContinueForEach
            Else
                <code else 3rd condition>
            End If
        Else
            <code else 2nd condition>
        End If
    Else
        <code else 1st condition>
    End If
ContinueForEach:
Next

const is pointless when the argument is passed by value since you will not be modifying the caller's object.

Wrong.

It's about self-documenting your code and your assumptions.

If your code has many people working on it and your functions are non-trivial then you should mark const any and everything that you can. When writing industrial-strength code, you should always assume that your coworkers are psychopaths trying to get you any way they can (especially since it's often yourself in the future).

Besides, as somebody mentioned earlier, it might help the compiler optimize things a bit (though it's a long shot).

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} );

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

Java 8+:

Set<String> copy = new HashSet<>(mySet); 

I got the same problem since I updated to latest version of Android Studio 0.3.7. So you can try with my stuffs.

Ensure you have updated to latest version Android Support Repository - 3 Android Support Library - 19

As your attachment picture above, you did it already. Then adding the following setting to your build.gradle

dependencies {
    compile 'com.android.support:support-v4:19.0.0'
}

One more thing: Please make sure your Android SDK is targeting to right SDK folder

I know that the question is too old, anyway:

select a, b from mytable group by a, b

will give your all the combinations.

There are at least two possible situations:

1. you are deleting the same entity twice
2. you are deleting something that wasn't allocated

For the first one I strongly suggest NULL-ing all deleted pointers.

You have three options:

1. overload new and delete and track the allocations
2. yes, use gdb -- then you'll get a backtrace from your crash, and that'll probably be very helpful
3. as suggested -- use Valgrind -- it isn't easy to get into, but it will save you time thousandfold in the future...

SELECT empname
FROM empdetails
WHERE salary IN(SELECT deptid max(salary) AS salary
FROM empdetails
group by deptid)

CDATA is a better general solution.

You can try this:

do {
   var op = prompt("please input operatot \n you most select one of * - / *  ")
} while (typeof op == "object" || op == ""); 
// execute block of code when click on cancle or ok whthout input

4gb RAM doesn't mean you can use it all for java process. Lots of RAM is needed for system processes. Dont go above 2GB or it will be trouble some.

Before starting jvm just check how much RAM is available and then set memory accordingly.

CardView gives you true shadow in android 5+ and it has a support library. Just wrap your view with it and you're done.

<android.support.v7.widget.CardView>
     <MyLayout>
</android.support.v7.widget.CardView>

It require the next dependency.

dependencies {
    ...
    compile 'com.android.support:cardview-v7:21.0.+'
}

A solution using modern-async's map():

import { map } from 'modern-async'

...
const result = await map(myArray, async (v) => {
    ...
})

The advantage of using that library is that you can control the concurrency using mapLimit() or mapSeries().

Rather than kludging it so you can continue, why not back up and wonder why you're running into a NaN in the first place?

If any of the numeric inputs to an operation is NaN, the output will also be NaN. That's the way the current IEEE Floating Point standard works (it's not just Javascript). That behavior is for a good reason: the underlying intention is to keep you from using a bogus result without realizing it's bogus.

The way NaN works is if something goes wrong way down in some sub-sub-sub-operation (producing a NaN at that lower level), the final result will also be NaN, which you'll immediately recognize as an error even if your error handling logic (throw/catch maybe?) isn't yet complete.

NaN as the result of an arithmetic calculation always indicates something has gone awry in the details of the arithmetic. It's a way for the computer to say "debugging needed here". Rather than finding some way to continue anyway with some number that's hardly ever right (is 0 really what you want?), why not find the problem and fix it.

A common problem in Javascript is that both parseInt(...) and parseFloat(...) will return NaN if given a nonsensical argument (null, '', etc). Fix the issue at the lowest level possible rather than at a higher level. Then the result of the overall calculation has a good chance of making sense, and you're not substituting some magic number (0 or 1 or whatever) for the result of the entire calculation. (The trick of (parseInt(foo.value) || 0) works only for sums, not products - for products you want the default value to be 1 rather than 0, but not if the specified value really is 0.)

Perhaps for ease of coding you want a function to retrieve a value from the user, clean it up, and provide a default value if necessary, like this:

function getFoobarFromUser(elementid) {
        var foobar = parseFloat(document.getElementById(elementid).innerHTML)
        if (isNaN(foobar)) foobar = 3.21;       // default value
        return(foobar.toFixed(2));
}

XML uses a tag structures for presenting items, like <tag>item</tag>, so an XML document is a set of tags nested into each other. And JSON syntax looks like a construction from Javascript language, with all stuff like lists and dictionaries:

{
 'attrib' : 'value',
 'array' : [1, 2, 3]
}

So if you use JSON it's really simple to use a JSON strings in many script languages, especially Javascript and Python.

We need to use Angular Js built in function $apply to acsess scope variables or functions outside the controller function.

This can be done in two ways :

|*| Method 1 : Using Id :

<div id="nameNgsDivUid" ng-app="">
    <a onclick="actNgsFnc()"> Activate Angular Scope</a><br><br>
    {{ nameNgsVar }}
</div>

<script type="text/javascript">

    var nameNgsDivVar = document.getElementById('nameNgsDivUid')

    function actNgsFnc()
    {
        var scopeNgsVar = angular.element(nameNgsDivVar).scope();
        scopeNgsVar.$apply(function()
        {
            scopeNgsVar.nameNgsVar = "Tst Txt";
        })
    }

</script>

|*| Method 2 : Using init of ng-controller :

<div ng-app="nameNgsApp" ng-controller="nameNgsCtl">
    <a onclick="actNgsFnc()"> Activate Angular Scope</a><br><br>
    {{ nameNgsVar }}
</div>

<script type="text/javascript">

    var scopeNgsVar;
    var nameNgsAppVar=angular.module("nameNgsApp",[])
    nameNgsAppVar.controller("nameNgsCtl",function($scope)
    {
        scopeNgsVar=$scope;
    })

    function actNgsFnc()
    {
        scopeNgsVar.$apply(function()
        {
            scopeNgsVar.nameNgsVar = "Tst Txt";
        })
    }

</script>

What is the matplotlib version you are running? I have recently had to upgrade to 1.1.0, and with it, add_subplot(111,aspect='equal') works for me.

I had two controllers with the same name defined in two different javascript files. Irritating that angular can't give a clearer error message indicating a namespace conflict.

Actually it can take more than 3 arguments. For instance if we want to check wether a number is positive, negative or zero we can do this:

String m= num > 0 ? "is a POSITIVE NUMBER.": num < 0 ?"is a NEGATIVE NUMBER." :"IT's ZERO.";

which is better than using if, else if, else.

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

The obvious subtext of this question is:

why can't you just use == to check if two strings are the same?

Perl doesn't have distinct data types for text vs. numbers. They are both represented by the type "scalar". Put another way, strings are numbers if you use them as such.

if ( 4 == "4" ) { print "true"; } else { print "false"; }
true

if ( "4" == "4.0" ) { print "true"; } else { print "false"; }
true

print "3"+4
7

Since text and numbers aren't differentiated by the language, we can't simply overload the == operator to do the right thing for both cases. Therefore, Perl provides eq to compare values as text:

if ( "4" eq "4.0" ) { print "true"; } else { print "false"; }
false

if ( "4.0" eq "4.0" ) { print "true"; } else { print "false"; }
true

In short:

• Perl doesn't have a data-type exclusively for text strings
• use == or !=, to compare two operands as numbers
• use eq or ne, to compare two operands as text

There are many other functions and operators that can be used to compare scalar values, but knowing the distinction between these two forms is an important first step.

You could just use: {in and out function callback}

$(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

For your example, better will be to use CSS pseudo class :hover: {no js/jquery needed}

.result {
    height: 72px;
    width: 100%;
    border: 1px solid #000;
  }
  .result:hover {
    background-color: #000;
  }

For anyone trying to this in react. There is a slight difference.

// Document of 8.5 inch width and 11 inch high
new jsPDF('p', 'in', [612, 792]);

or

// Document of 8.5 inch width and 11 inch high
new jsPDF({
        orientation: 'p', 
        unit: 'in', 
        format: [612, 792]
});

When i tried the @Aidiakapi solution the pages were tiny. For a difference size take size in inches * 72 to get the dimensions you need. For example, i wanted 8.5 so 8.5 * 72 = 612. This is for [email protected].

You could subscribe for the onkeypress event:

<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />

and then define the isNumber function:

function isNumber(evt) {
    evt = (evt) ? evt : window.event;
    var charCode = (evt.which) ? evt.which : evt.keyCode;
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        return false;
    }
    return true;
}

You can see it in action here.

This worked with me:

(-?[0-9]+(\.[0-9]+)?)

Group 1 is the your float number and group 2 is the fraction only.

but.onclick = callJavascriptFunction;

no double quotes no parentheses.

You may need to add a using statement to the file. The default Silverlight class template doesn't include it:

using System.Linq;

There are many very feature rich and ingenious answers already. To provide some contrast, I could make do with a very simple line.

# Check return value to see if there are incoming updates.
if ! git diff --quiet remotes/origin/HEAD; then
 # pull or whatever you want to do
fi

Try this:

long length = f.length();

All explanations here are great, but lacking a very important thing: How do you install production dependencies only? (without the development dependencies). We separate dependencies from devDependencies by using --save or --save-dev. To install all we use:

npm i

To install only production packages we should use:

npm i --only=production

Minor update on top of Karthik Bose's answer - you can configure git globally, to affect all of your workspaces to behave that way:

git config --global push.default upstream

Not with an iterator.

For org.json.JSONArray, you can do:

for (int i = 0; i < arr.length(); i++) {
  arr.getJSONObject(i);
}

For javax.json.JsonArray, you can do:

for (int i = 0; i < arr.size(); i++) {
  arr.getJsonObject(i);
}

My answer is not exactly what is asked in the question. Rather I am giving a solution exactly how easily we can read a file into out java application from our project class path.

For example suppose a config file name example.xml is located in a path like below:-

com.myproject.config.dev

and our java executable class file is in the below path:-

com.myproject.server.main

now just check in both the above path which is the nearest common directory/folder from where you can access both dev and main directory/folder (com.myproject.server.main - where our application’s java executable class is existed) – We can see that it is myproject folder/directory which is the nearest common directory/folder from where we can access our example.xml file. Therefore from a java executable class resides in folder/directory main we have to go back two steps like ../../ to access myproject. Now following this, see how we can read the file:-

package com.myproject.server.main;

class Example {

  File xmlFile;

  public Example(){
       String filePath = this.getClass().getResource("../../config/dev/example.xml").getPath();
       this.xmlFile = new File(filePath);
    }

  public File getXMLFile() {
      return this.xmlFile;
  }
   public static void main(String args[]){
      Example ex = new Example();
      File xmlFile = ex.getXMLFile();
   }
}

To initialize an array filled with zeros, you can use:

> Array.fill[Byte](5)(0)
Array(0, 0, 0, 0, 0)

This is equivalent to Java's new byte[5].

As a simplification to chrfin's response, since Chrome should be on the run path if installed, you could just call:

Process.Start("chrome.exe", "http://www.YourUrl.com");

This seem to work as expected for me, opening a new tab if Chrome is already open.

To resume the working solutions in VisualStudio 2013 and 2015 too:

Add an include-path to the current project only

In Solution Explorer (a palette-window of the VisualStudio-mainwindow), open the shortcut menu for the project and choose Properties, and then in the left pane of the Property Pages dialog box, expand Configuration Properties and select VC++ Directories. Additional include- or lib-paths are specifyable there.

Its the what Stackunderflow and user1741137 say in the answers above. Its the what Microsoft explains in MSDN too.

Add an include-path to every new project automatically

Its the question, what Jay Elston is asking in a comment above and what is a very obvious and burning question in my eyes, what seems to be nonanswered here yet.

There exist regular ways to do it in VisualStudio (see CurlyBrace.com), what in my experience are not working properly. In the sense, that it works only once, and thereafter, it is no more expandable and nomore removable. The approach of Steve Wilkinson in another close related thread of StackOverflow, editing the Microsoft-Factory-XML-file in the ‘program files’ - directory is probably a risky hack, as it isnt expected by Microsoft to meet there something foreign. The effect is potentally unpredictable. Well, I like rather to judge it risky not much, but anyway the best way to make VisualStudio work incomprehensible at least for someone else.

The what is working fine compared to, is the editing the corresponding User-XML-file:

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props

or/and

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user.props

For example:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ImportGroup Label="PropertySheets">
  </ImportGroup>
  <PropertyGroup Label="UserMacros" />
  <PropertyGroup>
    <IncludePath>C:\any-name\include;$(IncludePath)</IncludePath>
    <LibraryPath>C:\any-name\lib;$(LibraryPath)</LibraryPath>
  </PropertyGroup>
  <ItemDefinitionGroup />
  <ItemGroup />
</Project>

Where the directory ‘C:\any-name\include’ will get prepended to the present include-path and the directory ‘C:\any-name\lib’ to the library-path. Here, we can edit it ago in an extending and removing sense and remove it all, removing thewhole content of the tag .

Its the what makes VisualStudio itself, doing it in the regular way what CurlyBrace describes. As said, it isnt editable in the CurlyBrace-way thereafter nomore, but in the XML-editing-way it is.

For more insight, see Brian Tyler@MSDN-Blog 2009, what is admittedly not very fresh, but always the what Microsoft is linking to.

Bit late to the party but a good solution which is also Linq to SQL compatible is:

List<string> list1 = new List<string>() { "1", "2", "3" };
List<string> list2 = new List<string>() { "2", "4" };

List<string> inList1ButNotList2 = (from o in list1
                                   join p in list2 on o equals p into t
                                   from od in t.DefaultIfEmpty()
                                   where od == null
                                   select o).ToList<string>();

List<string> inList2ButNotList1 = (from o in list2
                                   join p in list1 on o equals p into t
                                   from od in t.DefaultIfEmpty()
                                   where od == null
                                   select o).ToList<string>();

List<string> inBoth = (from o in list1
                       join p in list2 on o equals p into t
                       from od in t.DefaultIfEmpty()
                       where od != null
                       select od).ToList<string>();

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

Try serialize. This will check nested subarrays as well.

$foo =serialize($array_foo);
$bar =serialize($array_bar);
if ($foo == $bar) echo "Foo and bar are equal";

You can use (mouseover) and (mouseout) events.

component.ts

changeText:boolean=true;

component.html

<div (mouseover)="changeText=true" (mouseout)="changeText=false">
  <span [hidden]="changeText">Hide</span>
  <span [hidden]="!changeText">Show</span>
</div>

It also works if you change the content type

    <form method="POST"
    action="http://localhost:8080/cms/customer/create_customer"
    id="frmRegister" name="frmRegister"
    enctype="application/x-www-form-urlencoded">

In the controller also add the header value as follows:

    @RequestMapping(value = "/create_customer", method = RequestMethod.POST, headers = "Content-Type=application/x-www-form-urlencoded")

If you prefer PERL, there is a short PERL script (originally written by Larry Wall, the creator of PERL) that will do exactly what you want here: tips.webdesign10.com/files/rename.pl.txt.

For your example the following should do the trick:

rename.pl 's/html/txt/' *.html

A bit late for probable answer, might help new people. In case you have multiple instances of database:

mongoimport --host <host_name>:<host_port> --db <database_name> --collection <collection_name>  --file <path_to_dump_file> -u <my_user> -p <my_pass>

Assuming credentials needed, otherwise remove this option.

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

I faced a similar issue. I checked for the below:

1. if ssh is not installed on your machine, you will have to install it firstly. (You will get a message saying ssh is not recognized as a command).
2. Port 22 is open or not on the server you are trying to ssh.
3. If the control of remote server is in your hands and you have permissions, try to disable firewall on it.
4. Try to ssh again.

If port is not an issue then you would have to check for firewall settings as it is the one that is blocking your connection.

For me too it was a firewall issue between my machine and remote server.I disabled the firewall on the remote server and I was able to make a connection using ssh.

If you are looking for features that notebooks in JupyterLab have that traditional Jupyter Notebooks do not, check out the JupyterLab notebooks documentation. There is a simple video showing how to use each of the features in the documentation link.

JupyterLab notebooks have the following features and more:

• Drag and drop cells to rearrange your notebook
• Drag cells between notebooks to quickly copy content (since you can
  have more than one open at a time)
• Create multiple synchronized views of a single notebook
• Themes and customizations: Dark theme and increase code font size

It is an old post, but I came across this recently

Selecting a specific interval

As @aleroot already mentioned, by using

table.setRowSelectionInterval(index0, index1);

You can specify an interval, which should be selected.

Adding an interval to the existing selection

You can also keep the current selection, and simply add additional rows by using this here

table.getSelectionModel().addSelectionInterval(index0, index1);

This line of code additionally selects the specified interval. It doesn't matter if that interval already is selected, of parts of it are selected.

IMPORTANT:

If you try to pass complex object that has many connected objects (e.g: a tree data structure, a list that has many objects...), the communication will fail no matter how you increased the Quotas. In such cases, you must increase the containing objects count:

I was having a similar problem today with a 2010 file with a large number of formulas and several database connections. The chart axis that were not updating references ranges with hidden columns, similar to others in this chain, and the labels displayed the month and year "MMM-YY" of the dynamic data. I tried all solutions listed except for the VBA options as I'd prefer to solve without code.

I was able to solve the issues by encapsulating my dates (the axis labels) in a TEXT formula as such: =TEXT(A10,"MMM-YY"). And everything immediately updates when values change. Happy days again!!!

From reading the other contributors issues above I started to think that the Charts were having problems with the DATE data type specifically, and therefore converting the values to text with the TEXT function resolved my issue. Hopefully this may help you as well. Just change the format within the double quotes (second argument of the TEXT function) to suit your needs.

The first case is indeed a syntax error.

Since I can't see the rest of your component, it's hard to see why you're nesting objects in your state here. It's not a good idea to nest objects in component state. Try setting your initial state to be:

this.state = {
  name: 'jasper',
  age: 28
}

That way, if you want to update the name, you can just call:

this.setState({
  name: 'Sean'
});

Will that achieve what you're aiming for?

For larger, more complex data stores, I would use something like Redux. But that's much more advanced.

The general rule with component state is to use it only to manage UI state of the component (e.g. active, timers, etc.)

Check out these references:

I tested a simple solution that works for me! My javascript was in a js separate file. What I did is that I placed the javascript for the new element into the html that was loaded with ajax, and it works fine for me! This is for those having big files of javascript!!

When you call document.write after a page has loaded it will eliminate all content and replace it with the parameter you provide. Instead use DOM methods to add content, for example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
var text = document.createTextNode('hi');
OpenWindow.document.body.appendChild(text);

If you want to use jQuery you get some better APIs to deal with. For example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).append('<p>hi</p>');

If you need the code to run after the new window's DOM is ready try:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).ready(function() {
    $(OpenWindow.document.body).append('<p>hi</p>');
});

This middleware will output every SQL query to your console, with color highlighting and execution time, it's been invaluable for me in optimizing some tricky requests

For me the problem was that I had weird configuration settings in file pydistutils.cfg

Try running rm ~/.pydistutils.cfg

You should try this syntax - assuming you want to have @OrderID as a parameter for your stored procedure:

CREATE PROCEDURE dbo.YourStoredProcNameHere
   @OrderID INT
AS
BEGIN
 DECLARE @OrderItemID AS INT
 DECLARE @AppointmentID AS INT
 DECLARE @PurchaseOrderID AS INT
 DECLARE @PurchaseOrderItemID AS INT
 DECLARE @SalesOrderID AS INT
 DECLARE @SalesOrderItemID AS INT

 SELECT @OrderItemID = OrderItemID 
 FROM [OrderItem] 
 WHERE OrderID = @OrderID

 SELECT @AppointmentID = AppoinmentID 
 FROM [Appointment] 
 WHERE OrderID = @OrderID

 SELECT @PurchaseOrderID = PurchaseOrderID 
 FROM [PurchaseOrder] 
 WHERE OrderID = @OrderID

END

OF course, that only works if you're returning exactly one value (not multiple values!)

SELECT author FROM lyrics WHERE author LIKE 'B%';

Make sure you have an index on author, though!

- name: copy vhosts
  template: src=site-vhost.conf dest=/etc/apache2/sites-enabled/{{ item }}.conf
  with_items:
    - somehost.local
    - otherhost.local
  notify: restart apache

IMPORTANT: Note that an item does not have to be just a string, it can be an object with as many properties as you like, so that way you can pass any number of variables.

In the template I have:

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName {{ item }}
    DocumentRoot /vagrant/public


    ErrorLog ${APACHE_LOG_DIR}/error-{{ item }}.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

You can see the differences b/w these two

import sys

for i in range(1,10 ):
    sys.stdout.write(str(i))
    sys.stdout.flush()

for i in range(1,10 ):
    print i

Below, code snippet, will help you in understanding the mutex-lock-unlock concept. Attempt dry-run on the code. (further by varying the wait-time and process-time, you can build you understanding).

Code for your reference:

#include <stdio.h>
#include <pthread.h>

void in_progress_feedback(int);

int global = 0;
pthread_mutex_t mutex;
void *compute(void *arg) {

    pthread_t ptid = pthread_self();
    printf("ptid : %08x \n", (int)ptid);    

    int i;
    int lock_ret = 1;   
    do{

        lock_ret = pthread_mutex_trylock(&mutex);
        if(lock_ret){
            printf("lock failed(%08x :: %d)..attempt again after 2secs..\n", (int)ptid,  lock_ret);
            sleep(2);  //wait time here..
        }else{  //ret =0 is successful lock
            printf("lock success(%08x :: %d)..\n", (int)ptid, lock_ret);
            break;
        }

    } while(lock_ret);

        for (i = 0; i < 10*10 ; i++) 
        global++;

    //do some stuff here
    in_progress_feedback(10);  //processing-time here..

    lock_ret = pthread_mutex_unlock(&mutex);
    printf("unlocked(%08x :: %d)..!\n", (int)ptid, lock_ret);

     return NULL;
}

void in_progress_feedback(int prog_delay){

    int i=0;
    for(;i<prog_delay;i++){
    printf(". ");
    sleep(1);
    fflush(stdout);
    }

    printf("\n");
    fflush(stdout);
}

int main(void)
{
    pthread_t tid0,tid1;
    pthread_mutex_init(&mutex, NULL);
    pthread_create(&tid0, NULL, compute, NULL);
    pthread_create(&tid1, NULL, compute, NULL);
    pthread_join(tid0, NULL);
    pthread_join(tid1, NULL);
    printf("global = %d\n", global);
    pthread_mutex_destroy(&mutex);
          return 0;
}

You can link to file, but not to folders, and keep in mind that, Github will add /blob/master/ before your relative link(and folders lacks that part so they cannot be linked, neither with HTML <a> tags or Markdown link).

So, if we have a file in myrepo/src/Test.java, it will have a url like:

https://github.com/WesternGun/myrepo/blob/master/src/Test.java

And to link it in the readme file, we can use:

[This is a link](src/Test.java)

or: <a href="src/Test.java">This is a link</a>.

(I guess, master represents the master branch and it differs when the file is in another branch.)

Seems there is another format now

where: {
    LastName: "Doe",
    $or: [
        {
            FirstName: 
            {
                $eq: "John"
            }
        }, 
        {
            FirstName: 
            {
                $eq: "Jane"
            }
        }, 
        {
            Age: 
            {
                $gt: 18
            }
        }
    ]
}

Will generate

WHERE LastName='Doe' AND (FirstName = 'John' OR FirstName = 'Jane' OR Age > 18)

See the doc: http://docs.sequelizejs.com/en/latest/docs/querying/#where

Well, nothing in the previous answers worked for me, so it got me thinking about why am I clicking and hoping when as developers we should really try to understand what is going on here.

It seemed obvious to me that this incorrect meta data file reference must be held somewhere.

A quick search of the .csproj file showed the guilty lines. I had a section called <itemGroup> that seemed to be hanging onto the old incorrect filepath.

<ItemGroup>
    <ProjectReference Include="..\..\..\MySiteOld\MySite.Entities\MySite.Entities.csproj">
        <Project>{5b0a347e-cd9a-4746-a3b6-99d6d010a6c2}</Project>
        <Name>Beeyp.Entities</Name>
    </ProjectReference>
...

So a simple fix really:

1. Backup your .csproj file.
2. Find the incorrect paths in the .csproj file and rename appropriately.

Please make sure you backup your old .csproj before you fiddle.

In year of 2020, these code seems to return exception as

System.Net.Mail.SmtpStatusCode.MustIssueStartTlsFirst or The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM

This code is working for me.

            using (SmtpClient client = new SmtpClient()
            {
                Host = "smtp.office365.com",
                Port = 587,
                UseDefaultCredentials = false, // This require to be before setting Credentials property
                DeliveryMethod = SmtpDeliveryMethod.Network,
                Credentials = new NetworkCredential("[email protected]", "password"), // you must give a full email address for authentication 
                TargetName = "STARTTLS/smtp.office365.com", // Set to avoid MustIssueStartTlsFirst exception
                EnableSsl = true // Set to avoid secure connection exception
            })
            {

                MailMessage message = new MailMessage()
                {
                    From = new MailAddress("[email protected]"), // sender must be a full email address
                    Subject = subject,
                    IsBodyHtml = true,
                    Body = "<h1>Hello World</h1>",
                    BodyEncoding = System.Text.Encoding.UTF8,
                    SubjectEncoding = System.Text.Encoding.UTF8,

                };
                var toAddresses = recipients.Split(',');
                foreach (var to in toAddresses)
                {
                    message.To.Add(to.Trim());
                }

                try
                {
                    client.Send(message);
                }
                catch (Exception ex)
                {
                    Debug.WriteLine(ex.Message);
                }
            }

To select the item from the contextual menu, you have to just move your mouse positions with the use of Key down event like this:-

Actions action= new Actions(driver);
action.contextClick(productLink).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();

hope this will works for you. Have a great day :)

I also had this problem with another style of implementation but I forgot where I got it since it was 2 years ago.

static string sha256(string randomString)
{
    var crypt = new SHA256Managed();
    string hash = String.Empty;
    byte[] crypto = crypt.ComputeHash(Encoding.ASCII.GetBytes(randomString));
    foreach (byte theByte in crypto)
    {
        hash += theByte.ToString("x2");
    }
    return hash;
}

When I input something like abcdefghi2013 for some reason it gives different results and results in errors in my login module. Then I tried modifying the code the same way as suggested by Quuxplusone and changed the encoding from ASCII to UTF8 then it finally worked!

static string sha256(string randomString)
{
    var crypt = new System.Security.Cryptography.SHA256Managed();
    var hash = new System.Text.StringBuilder();
    byte[] crypto = crypt.ComputeHash(Encoding.UTF8.GetBytes(randomString));
    foreach (byte theByte in crypto)
    {
        hash.Append(theByte.ToString("x2"));
    }
    return hash.ToString();
}

Thanks again Quuxplusone for the wonderful and detailed answer! :)

Some people are answering the wrong question, it seems. You said you want to do:

>>> first_item, last_item = some_list[0,-1]
>>> print first_item
'1'
>>> print last_item
'F'

Ie., you want to extract the first and last elements each into separate variables.

In this case, the answers by Matthew Adams, pemistahl, and katrielalex are valid. This is just a compound assignment:

first_item, last_item = some_list[0], some_list[-1]

But later you state a complication: "I am splitting it in the same line, and that would have to spend time splitting it twice:"

x, y = a.split("-")[0], a.split("-")[-1]

So in order to avoid two split() calls, you must only operate on the list which results from splitting once.

In this case, attempting to do too much in one line is a detriment to clarity and simplicity. Use a variable to hold the split result:

lst = a.split("-")
first_item, last_item = lst[0], lst[-1]

Other responses answered the question of "how to get a new list, consisting of the first and last elements of a list?" They were probably inspired by your title, which mentions slicing, which you actually don't want, according to a careful reading of your question.

AFAIK are 3 ways to get a new list with the 0th and last elements of a list:

>>> s = 'Python ver. 3.4'
>>> a = s.split()
>>> a
['Python', 'ver.', '3.4']

>>> [ a[0], a[-1] ]        # mentioned above
['Python', '3.4']

>>> a[::len(a)-1]          # also mentioned above
['Python', '3.4']

>>> [ a[e] for e in (0,-1) ] # list comprehension, nobody mentioned?
['Python', '3.4']

# Or, if you insist on doing it in one line:
>>> [ s.split()[e] for e in (0,-1) ]
['Python', '3.4']

The advantage of the list comprehension approach, is that the set of indices in the tuple can be arbitrary and programmatically generated.

For those who are wondering why this works in Java but not C#, consider what happens if some doof wrote this class:

public class Trololol : ISignatur<bool>, ISignatur<int>{
    Type ISignatur<bool>.Type => typeof(bool);
    Type ISignatur<int>.Type => typeof(int);
}

How is the compiler supposed to resolve var access = service.Get(new Trololol())? Both int and bool are valid.

The reason this implicit resolution works in Java likely has to do with Erasure and how Java will throw a fit if you try to implement an interface with two or more different type arguments. Such a class is simply not allowed in Java, but is just fine in C#.

On the Developers bugs Facebook site, the last answer about that (parameters with sharer.php), makes me believe it was a bug that was going to be resolved. Am I right?

According to http://wiki.python.org/moin/TkInter :

If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.

If the function is not defined when using that function in html, such as onclick = ‘function () ', it means function is in a callback, in my case is 'DOMContentLoaded'.

By adding using System.Timers; to your program you can use this function:

private static void delay(int Time_delay)
{
   int i=0;
  //  ameTir = new System.Timers.Timer();
    _delayTimer = new System.Timers.Timer();
    _delayTimer.Interval = Time_delay;
    _delayTimer.AutoReset = false; //so that it only calls the method once
    _delayTimer.Elapsed += (s, args) => i = 1;
    _delayTimer.Start();
    while (i == 0) { };
}

Delay is a function and can be used like:

delay(5000);

You need to add a reference to System.Web.Extensions.dll in project for System.Web.Script.Serialization error.

Assuming that you have a data frame called students, you can select individual rows or columns using the bracket syntax, like this:

• students[1,2] would select row 1 and column 2, the result here would be a single cell.
• students[1,] would select all of row 1, students[,2] would select all of column 2.

If you'd like to select multiple rows or columns, use a list of values, like this:

• students[c(1,3,4),] would select rows 1, 3 and 4,
• students[c("stu1", "stu2"),] would select rows named stu1 and stu2.

Hope I could help.

Here's one other css only method that works pretty well and is based on this: http://zerosixthree.se/vertical-align-anything-with-just-3-lines-of-css/

sass:

.modal {
    height: 100%;

    .modal-dialog {
        top: 50% !important;
        margin-top:0;
        margin-bottom:0;
    }

    //keep proper transitions on fade in
    &.fade .modal-dialog {
        transform: translateY(-100%) !important;
    }
    &.in .modal-dialog {
        transform: translateY(-50%) !important;
    }
}

A possible alternative approach in Excel 2010 or later versions:

AGGREGATE(6,6,A1,B1)

In AGGREGATE function the first 6 indicates PRODUCT operation and the second 6 denotes "ignore errors"

Alongside the classic causes, mentioned elsewhere:

• Make sure you've called setContentView() before findViewById()
• Make sure that the id you want is in the view or layout you've given to setContentView()
• Make sure that the id isn't accidentally duplicated in different layouts

There is one I have found for custom views in standard layouts, which goes against the documentation:

In theory you can create a custom view and add it to a layout (see here). However, I have found that in such situations, sometimes the id attribute works for all the views in the layout except the custom ones. The solution I use is:

1. Replace each custom view with a FrameLayout with the same layout properties as you would like the custom view to have. Give it an appropriate id, say frame_for_custom_view.

2. In onCreate:

   setContentView(R.layout.my_layout);
   FrameView fv = findViewById(R.id.frame_for_custom_layout);
   MyCustomView cv = new MyCustomView(context);
   fv.addView(cv);
   

   which puts the custom view in the frame.

Possible Suggestions to make it work:

Some modifications (U forgot to include a semicolon in the statement this.getName=function(){...} it should be this.getName=function(){...};)

function Customer(){
this.name="Jhon";
this.getName=function(){
return this.name;
};
}

(This might be one of the problem.)

and

Make sure U Link the JS files in the correct order

<script src="file1.js" type="text/javascript"></script>
<script src="file2.js" type="text/javascript"></script>

Here are the common characters which need to be escaped in XML, starting with double quotes:

1. double quotes (") are escaped to "
2. ampersand (&) is escaped to &
3. single quotes (') are escaped to '
4. less than (<) is escaped to <
5. greater than (>) is escaped to >

Bottom right hand corner on the status bar, click Spaces: N (or Tab Width: N, where N is an integer), ensure it says Tab Width: 4 for converting from four spaces, and then select Convert Indentation to Tabs from the contextual menu that will appear from the initial click.

Similarly, if you want to do the opposite, click the Spaces or Tab Width text on the status bar and select from the same menu.

[>=1000]#,##0,"K";[<=-1000]-#,##0,"K";0

teylyn's answer is great. This just adds negatives beyond -1000 following the same format.

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

A slightly different approach will allow you to skip GDB entirely. If all you want is a backtrace, the Linux-specific utility 'catchsegv' will catch SIGSEGV and display a backtrace.

Try:

#!/bin/bash
# .... some previous code ...
# help set exec | less
set -- 1 2 3 4 5  # fake command line arguments
exec bash --login -c '
echo $0
echo $@
echo my script continues here

There are actually two ways in which strings can be made in javascript.

1. var str = 'Javascript'; This creates a primitive string value.

2. var obj = new String('Javascript'); This creates a wrapper object of type String.

   typeof str // string
typeof obj // object

So the best way to check for equality is using the === operator because it checks value as well as type of both operands.

If you want to check for equality between two objects then using String.prototype.valueOf is the correct way.

new String('javascript').valueOf() == new String('javascript').valueOf()

Aioobe's approach is the way to go. I would like to suggest the following improvement over his solution though.

class SortedList<T> extends ArrayList<T> {

    public void insertSorted(T value) {
        int insertPoint = insertPoint(value);
        add(insertPoint, value);
    }

    /**
     * @return The insert point for a new value. If the value is found the insert point can be any
     * of the possible positions that keeps the collection sorted (.33 or 3.3 or 33.).
     */
    private int insertPoint(T key) {
        int low = 0;
        int high = size() - 1;

        while (low <= high) {
            int mid = (low + high) >>> 1;
            Comparable<? super T> midVal = (Comparable<T>) get(mid);
            int cmp = midVal.compareTo(key);

            if (cmp < 0)
                low = mid + 1;
            else if (cmp > 0)
                high = mid - 1;
            else {
                return mid; // key found
            }
        }

        return low;  // key not found
    }
}

aioobe's solution gets very slow when using large lists. Using the fact that the list is sorted allows us to find the insert point for new values using binary search.

I would also use composition over inheritance, something along the lines of

SortedList<E> implements List<E>, RandomAccess, Cloneable, java.io.Serializable

The code you have posted doesn't include a call to mysql_fetch_array(). However, what is most likely going wrong is that you are issuing a query that returns an error message, in which case the return value from the query function is false, and attempting to call mysql_fetch_array() on it doesn't work (because boolean false is not a mysql result object).

Let's assume you have a class like this:

public class Staff
{
    public int ID { get; set; }
    public string Name { get; set; }
}

And assume you have dragged and dropped a DataGridView to your form, and name it dataGridView1.

You need a BindingSource to hold your data to bind your DataGridView. This is how you can do it:

private void frmDGV_Load(object sender, EventArgs e)
{
    //dummy data
    List<Staff> lstStaff = new List<Staff>();
    lstStaff.Add(new Staff()
    {
        ID = 1,
        Name = "XX"
    });
    lstStaff.Add(new Staff()
    {
        ID = 2,
        Name = "YY"
    });

    //use binding source to hold dummy data
    BindingSource binding = new BindingSource();
    binding.DataSource = lstStaff;

    //bind datagridview to binding source
    dataGridView1.DataSource = binding;
}

I guess you could try

table tr td { color: red; }
table tr td table tr td { color: black; }

Or

body table tr td { color: red; }

where 'body' is a selector for your table's parent

But classes are most likely the right way to go here.

Because thats coding convention. See here for more.

Below Python packages are to be downloaded and installed to their default locations.

1.1. Python-2.7.x.

1.2. Numpy.

1.3. Matplotlib (Matplotlib is optional, but recommended since we use it a lot in our tutorials).

Install all packages into their default locations. Python will be installed to C:/Python27/.

After installation, open Python IDLE. Enter import numpy and make sure Numpy is working fine.

Download latest OpenCV release from sourceforge site and double-click to extract it.

Goto opencv/build/python/2.7 folder.

Copy cv2.pyd to C:/Python27/lib/site-packeges.

Open Python IDLE and type following codes in Python terminal.

import cv2 print cv2.version If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully.

It IS possible, using something like the below example that I put together with the help of work from (https://gist.github.com/bitinn/1700068a276fb29740a7) that didn't quite work on iOS 11:

Here's the modified code that works on iOS 11.03, please comment if it worked for you.

I have the following config in my private project:

git config alias.auto 'commit -a -m "changes made from [device name]"'

That way, when I'm in a hurry I do

git auto
git push

And at least I know what device the commit was made from.

You don't need a whole function for this; a simple cast will suffice:

int x;
static_cast<char*>(static_cast<void*>(&x));

Any object in C++ can be reinterpreted as an array of bytes. If you want to actually make a copy of the bytes into a separate array, you can use std::copy:

int x;
char bytes[sizeof x];
std::copy(static_cast<const char*>(static_cast<const void*>(&x)),
          static_cast<const char*>(static_cast<const void*>(&x)) + sizeof x,
          bytes);

Neither of these methods takes byte ordering into account, but since you can reinterpret the int as an array of bytes, it is trivial to perform any necessary modifications yourself.

As said by JW, you can't find the current focused element, at least in a browser-independent way. But if your app is IE only (some are...), you can find it the following way :

document.activeElement

EDIT: It looks like IE did not have everything wrong after all, this is part of HTML5 draft and seems to be supported by the latest version of Chrome, Safari and Firefox at least.

apply() was added in 2.3, it commits without returning a boolean indicating success or failure.

commit() returns true if the save works, false otherwise.

apply() was added as the Android dev team noticed that almost no one took notice of the return value, so apply is faster as it is asynchronous.

Dockerfile

A Dockerfile is a simple text file that contains the commands a user could call to assemble an image.

Example, Dockerfile

FROM ubuntu:latest
MAINTAINER john doe 

RUN apt-get update
RUN apt-get install -y python python-pip wget
RUN pip install Flask

ADD hello.py /home/hello.py

WORKDIR /home

Docker Compose

Docker Compose

• is a tool for defining and running multi-container Docker applications.

• define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.

• get an app running in one command by just running docker-compose up

Example, docker-compose.yml

version: "3"
services:
  web:
    build: .
    ports:
    - '5000:5000'
    volumes:
    - .:/code
    - logvolume01:/var/log
    links:
    - redis
  redis:
    image: redis
    volumes:
      logvolume01: {}

It is because one of the DBs the column was created with " which makes its name case-sensitive.

Oracle Table Column Name : GoodRec Hive cannot recognize case sensitivity : ERROR thrown was - Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "GOODREC": invalid identifier

Solution : Rename Oracle column name to all caps.

No, there is no bool in ISO C90.

Here's a list of keywords in standard C (not C99):

• auto
• break
• case
• char
• const
• continue
• default
• do
• double
• else
• enum
• extern
• float
• for
• goto
• if
• int
• long
• register
• return
• short
• signed
• static
• struct
• switch
• typedef
• union
• unsigned
• void
• volatile
• while

Here's an article discussing some other differences with C as used in the kernel and the standard: http://www.ibm.com/developerworks/linux/library/l-gcc-hacks/index.html

• Only one import needed.
• No if statement needed.
• Use the client built-in exception as intended.

Ex:

from boto3 import client

cli = client('iam')
try:
    cli.create_user(
        UserName = 'Brian'
    )
except cli.exceptions.EntityAlreadyExistsException:
    pass

a CloudWatch example:

cli = client('logs')
try:
    cli.create_log_group(
        logGroupName = 'MyLogGroup'
    )
except cli.exceptions.ResourceAlreadyExistsException:
    pass

My simple solution here is:

const isNumeric = (val: string) : boolean => {
   return !isNaN(Number(val));
}

// isNumberic("2") => true
// isNumeric("hi") => false;

As one person may have already suggested,

I passed the ISO 8601 date string directly to moment like so...

`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`

or

`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`

either of these solutions will give you the same result.

`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`

I had a similiar problem but ./sdkmanager --licenses didnt work. I follow this thread and "obladors" comment gave me the solution: https://github.com/oblador/react-native-vector-icons/issues/527

What eventually solved my problem was: Running ./sdkmanager "build-tools;23.0.1"

Change 23.0.1 with your version

Will something like this work for you?

>>> def namestr(**kwargs):
...     for k,v in kwargs.items():
...       print "%s = %s" % (k, repr(v))
...
>>> namestr(a=1, b=2)
a = 1
b = 2

And in your example:

>>> choice = {'key': 24; 'data': None}
>>> namestr(choice=choice)
choice = {'data': None, 'key': 24}
>>> printvars(**globals())
__builtins__ = <module '__builtin__' (built-in)>
__name__ = '__main__'
__doc__ = None
namestr = <function namestr at 0xb7d8ec34>
choice = {'data': None, 'key': 24}

You have to disable Globals

 /**
 * @backupGlobals disabled
 */

The answer of Logan Capaldo is correct but can be marginally simplified because it is unnecessary to specialize the class every time. One can write:

// in header
template<typename T>
struct TypeParseTraits
{ static const char* name; };

// in c-file
#define REGISTER_PARSE_TYPE(X) \
    template <> const char* TypeParseTraits<X>::name = #X

REGISTER_PARSE_TYPE(int);
REGISTER_PARSE_TYPE(double);
REGISTER_PARSE_TYPE(FooClass);
// etc...

This also allows you to put the REGISTER_PARSE_TYPE instructions in a C++ file...

You can Use the following function in you code directly,

    function artoxml($arr, $i=1,$flag=false){
    $sp = "";
    for($j=0;$j<=$i;$j++){
        $sp.=" ";
     }
    foreach($arr as $key=>$val){
        echo "$sp&lt;".$key."&gt;";
        if($i==1) echo "\n";
        if(is_array($val)){
            if(!$flag){echo"\n";}
            artoxml($val,$i+5);
            echo "$sp&lt;/".$key."&gt;\n";
        }else{
              echo "$val"."&lt;/".$key."&gt;\n";
         }
    }

}

Call the function with first argument as your array and the second argument must be 1, this will be increased for perfect indentation, and third must be true.

for example, if the array variable to be converted is $array1 then, calling would be, the calling function should be encapsulated with <pre> tag.

  artoxml($array1,1,true);   

Please see the page source after executing the file, because the < and > symbols won't be displayed in a html page.

I had the same problem.I solved with following command maven:

mvn eclipse:eclipse -Dwtpversion=2.0

PS: My project is WTP plugin

Create a configuration file and put your entries there.

SERVER_PORT=10000     
THREAD_POOL_COUNT=3     
ROOT_DIR=/home/   

You can load this file using Properties.load(fileName) and retrieved values you get(key);

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.

That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:

<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" /> 

(if you are using XML)

or

@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")

(if you are using Java Config)

I'd use a regular expression:

function someFunction(site)
{
// if site has an end slash (like: www.example.com/),
// then remove it and return the site without the end slash
return site.replace(/\/$/, '') // Match a forward slash / at the end of the string ($)
}

You'll want to make sure that the variable site is a string, though.

When I need this kind of functionality in Java, I usually use the Observer pattern. It does imply an extra object, but I think it's a clean way to go, and is a widely understood pattern, which helps with code readability.

Being driven by "use as strict modifier as you can" rule I use internal everywhere I need to access, say, method from another class until I explicitly need to access it from another assembly.

As assembly interface is usually more narrow than sum of its classes interfaces, there are quite many places I use it.

Form isn't included in laravel 5.0 as it was on 4.0, steps to include it:

Begin by installing laravelcollective/html package through Composer. Edit your project's composer.json file to require:

"require": {
    "laravelcollective/html": "~5.0"
}

Next, update composer from the Terminal:

composer update

Next, add your new provider to the providers array of config/app.php:

'providers' => [
  // ...
  'Collective\Html\HtmlServiceProvider',
  // ...
],

Finally, add two class aliases to the aliases array of config/app.php:

'aliases' => [
// ...
  'Form' => 'Collective\Html\FormFacade',
  'Html' => 'Collective\Html\HtmlFacade',
// ...
],

At this point, Form should be working

Source

Update Laravel 5.8 (2019-04-05):

In Laravel 5.8, the providers in the config/app.php can be declared as:

Collective\Html\HtmlServiceProvider::class,

instead of:

'Collective\Html\HtmlServiceProvider',

This notation is the same for the aliases.

This solutions sounds crazy, but works smooth as honey

import csv

with open('filename', 'wb') as myfile:
    wr = csv.writer(myfile, quoting=csv.QUOTE_ALL,delimiter='\n')
    wr.writerow(mylist)

The file is being written by csvwriter hence csv properties are maintained i.e. comma separated. The delimiter helps in the main part by moving list items to next line, each time.

In the first case alternatively to multiline forEach you can use the peek stream operation:

entryList.stream()
         .peek(entry -> entry.setTempId(tempId))
         .forEach(updatedEntries.add(entityManager.update(entry, entry.getId())));

In the second case I'd suggest to extract the loop body to the separate method and use method reference to call it via forEach. Even without lambdas it would make your code more clear as the loop body is independent algorithm which processes the single entry so it might be useful in other places as well and can be tested separately.

Update after question editing. if you have checked exceptions then you have two options: either change them to unchecked ones or don't use lambdas/streams at this piece of code at all.

apache commons Fileutils is handy. you can do below activities.

1. copying file from one directory to another directory.

   use copyFileToDirectory(File srcFile, File destDir)

2. copying directory from one directory to another directory.

   use copyDirectory(File srcDir, File destDir)

3. copying contents of one file to another

   use static void copyFile(File srcFile, File destFile)

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

Checkboxes, by design, are meant to be toggled on or off. They are not dependent on other checkboxes, so you can turn as many on and off as you wish.

Radio buttons, however, are designed to only allow one element of a group to be selected at any time.

From memory, you call stringstream::str() to get the std::string value out.

Nice that you brought this subject up.

This is an important thing/concept in git that a lof of git users would benefit from knowing. git rebase is a very powerful tool and enables you to squash commits together, remove commits etc. But as with any powerful tool, you basically need to know what you're doing or something might go really wrong.

When you are working locally and messing around with your local branches, you can do whatever you like as long as you haven't pushed the changes to the central repository. This means you can rewrite your own history, but not others history. By only messing around with your local stuff, nothing will have any impact on other repositories.

This is why it's important to remember that once you have pushed commits, you should not rebase them later on. The reason why this is important, is that other people might pull in your commits and base their work on your contributions to the code base, and if you later on decide to move that content from one place to another (rebase it) and push those changes, then other people will get problems and have to rebase their code. Now imagine you have 1000 developers :) It just causes a lot of unnecessary rework.

<head>
    <script type="text/javascript">
        function SetMaxLength () {
            var input = document.getElementById ("myInput");
            input.maxLength = 10;
        }
    </script>
</head>
<body>
    <input id="myInput" type="text" size="20" />
</body>

Give this a try:

$(document).ready(function(){
  $("#topbar-show").toggle(function(){
    $(this).animate({height:40},200);
  },function(){
    $(this).animate({height:10},200);
  });
});

An Example with python3 and the requests library as mentioned by @leoluk:

pip install requests

Script req.py:

import requests

url='http://localhost'

# in case you need a session
cd = { 'sessionid': '123..'}

r = requests.get(url, cookies=cd)
# or without a session: r = requests.get(url)
r.content

Now,execute it and you will get the html source of localhost!

python3 req.py

The syntaxes

int[]

and

int[X] // Where X is a compile-time positive integer

are exactly the same as

int*

when in a function parameter list (I left out the optional names).

Additionally, an array name decays to a pointer to the first element when passed to a function (and not passed by reference) so both int firstarray[3] and int secondarray[5] decay to int*s.

It also happens that both an array dereference and a pointer dereference with subscript syntax (subscript syntax is x[y]) yield an lvalue to the same element when you use the same index.

These three rules combine to make the code legal and work how you expect; it just passes pointers to the function, along with the length of the arrays which you cannot know after the arrays decay to pointers.

It should be:

SELECT SalesID, COUNT(*)
FROM AXDelNotesNoTracking
GROUP BY SalesID
HAVING COUNT(*) > 1

Regarding your initial query:

1. You cannot do a SELECT * since this operation requires a GROUP BY and columns need to either be in the GROUP BY or in an aggregate function (i.e. COUNT, SUM, MIN, MAX, AVG, etc.)
2. As this is a GROUP BY operation, a HAVING clause will filter it instead of a WHERE

Edit:

And I just thought of this, if you want to see WHICH items are in there more than once (but this depends on which database you are using):

;WITH cte AS (
    SELECT  *, ROW_NUMBER() OVER (PARTITION BY SalesID ORDER BY SalesID) AS [Num]
    FROM    AXDelNotesNoTracking
)
SELECT  *
FROM    cte
WHERE   cte.Num > 1

Of course, this just shows the rows that have appeared with the same SalesID but does not show the initial SalesID value that has appeared more than once. Meaning, if a SalesID shows up 3 times, this query will show instances 2 and 3 but not the first instance. Still, it might help depending on why you are looking for multiple SalesID values.

Edit2:

The following query was posted by APC below and is better than the CTE I mention above in that it shows all rows in which a SalesID has appeared more than once. I am including it here for completeness. I merely added an ORDER BY to keep the SalesID values grouped together. The ORDER BY might also help in the CTE above.

SELECT *
FROM AXDelNotesNoTracking
WHERE SalesID IN
    (     SELECT SalesID
          FROM AXDelNotesNoTracking
          GROUP BY SalesID
          HAVING COUNT(*) > 1
    )
ORDER BY SalesID

awk

awk '{gsub(/two.*/,"")}1' file

Ruby

ruby -ne 'print $_.gsub(/two.*/,"")' file

If you want to return the original string untouched if it does not contain the search character then you can use an anonymous function (a closure):

var streetaddress=(function(s){var i=s.indexOf(',');
   return i==-1 ? s : s.substr(0,i);})(addy);

This can be made more generic:

var streetaddress=(function(s,c){var i=s.indexOf(c);
   return i==-1 ? s : s.substr(0,i);})(addy,',');

Just use:

git stash -u

Done. Easy.

If you really care about your stash stack then you can follow with git stash drop. But at that point you're better off using (from Mariusz Nowak):

git checkout -- .
git clean -df

Nonetheless, I like git stash -u the best because it "discards" all tracked and untracked changes in just one command. Yet git checkout -- . only discards tracked changes, and git clean -df only discards untracked changes... and typing both commands is far too much work :)

The aim of using StringBuilder, i.e reducing memory. Is it achieved?

No, not at all. That code is not using StringBuilder correctly. (I think you've misquoted it, though; surely there aren't quotes around id2 and table?)

Note that the aim (usually) is to reduce memory churn rather than total memory used, to make life a bit easier on the garbage collector.

Will that take memory equal to using String like below?

No, it'll cause more memory churn than just the straight concat you quoted. (Until/unless the JVM optimizer sees that the explicit StringBuilder in the code is unnecessary and optimizes it out, if it can.)

If the author of that code wants to use StringBuilder (there are arguments for, but also against; see note at the end of this answer), better to do it properly (here I'm assuming there aren't actually quotes around id2 and table):

StringBuilder sb = new StringBuilder(some_appropriate_size);
sb.append("select id1, ");
sb.append(id2);
sb.append(" from ");
sb.append(table);
return sb.toString();

Note that I've listed some_appropriate_size in the StringBuilder constructor, so that it starts out with enough capacity for the full content we're going to append. The default size used if you don't specify one is 16 characters, which is usually too small and results in the StringBuilder having to do reallocations to make itself bigger (IIRC, in the Sun/Oracle JDK, it doubles itself [or more, if it knows it needs more to satisfy a specific append] each time it runs out of room).

You may have heard that string concatenation will use a StringBuilder under the covers if compiled with the Sun/Oracle compiler. This is true, it will use one StringBuilder for the overall expression. But it will use the default constructor, which means in the majority of cases, it will have to do a reallocation. It's easier to read, though. Note that this is not true of a series of concatenations. So for instance, this uses one StringBuilder:

return "prefix " + variable1 + " middle " + variable2 + " end";

It roughly translates to:

StringBuilder tmp = new StringBuilder(); // Using default 16 character size
tmp.append("prefix ");
tmp.append(variable1);
tmp.append(" middle ");
tmp.append(variable2);
tmp.append(" end");
return tmp.toString();

So that's okay, although the default constructor and subsequent reallocation(s) isn't ideal, the odds are it's good enough — and the concatenation is a lot more readable.

But that's only for a single expression. Multiple StringBuilders are used for this:

String s;
s = "prefix ";
s += variable1;
s += " middle ";
s += variable2;
s += " end";
return s;

That ends up becoming something like this:

String s;
StringBuilder tmp;
s = "prefix ";
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable1);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" middle ");
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable2);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" end");
s = tmp.toString();
return s;

...which is pretty ugly.

It's important to remember, though, that in all but a very few cases it doesn't matter and going with readability (which enhances maintainability) is preferred barring a specific performance issue.
