Use the iFrame's .onload function of JavaScript:

<iframe id="my_iframe" src="http://www.test.tld/">
    <script type="text/javascript">
        document.getElementById('my_iframe').onload = function() {
            __doPostBack('ctl00$ctl00$bLogout','');
        }
    </script>
    <!--OTHER STUFF-->
</iframe>

You should really use the following instead (works in all newer browsers):

window.addEventListener('DOMContentLoaded', init, false);

Just go to project.plist then add Supported interface orientation and then add only Portrait (bottom home button) and Portrait (top home button).

You can add or remove there orientation as per your project requirement .

You might consider Digest Access Authentication. Essentially the protocol is as follows:

1. Request is made from client
2. Server responds with a unique nonce string
3. Client supplies a username and password (and some other values) md5 hashed with the nonce; this hash is known as HA1
4. Server is then able to verify client's identity and serve up the requested materials
5. Communication with the nonce can continue until the server supplies a new nonce (a counter is used to eliminate replay attacks)

All of this communication is made through headers, which, as jmort253 points out, is generally more secure than communicating sensitive material in the url parameters.

Digest Access Authentication is supported by Spring Security. Notice that, although the docs say that you must have access to your client's plain-text password, you can successfully authenticate if you have the HA1 hash for your client.

You can use the following class to pinpoint transitivity bugs in your Comparators:

/**
 * @author Gili Tzabari
 */
public final class Comparators
{
    /**
     * Verify that a comparator is transitive.
     *
     * @param <T>        the type being compared
     * @param comparator the comparator to test
     * @param elements   the elements to test against
     * @throws AssertionError if the comparator is not transitive
     */
    public static <T> void verifyTransitivity(Comparator<T> comparator, Collection<T> elements)
    {
        for (T first: elements)
        {
            for (T second: elements)
            {
                int result1 = comparator.compare(first, second);
                int result2 = comparator.compare(second, first);
                if (result1 != -result2)
                {
                    // Uncomment the following line to step through the failed case
                    //comparator.compare(first, second);
                    throw new AssertionError("compare(" + first + ", " + second + ") == " + result1 +
                        " but swapping the parameters returns " + result2);
                }

        }

            {
                int firstGreaterThanSecond = comparator.compare(first, second);
                if (firstGreaterThanSecond <= 0)
                    continue;
                for (T third: elements)
                {

                    {
                        // Uncomment the following line to step through the failed case
                        //comparator.compare(first, third);
                        throw new AssertionError("compare(" + first + ", " + second + ") > 0, " +

                            firstGreaterThanThird);
                    }
                }
            }
        }
    }

    /**
     * Prevent construction.

    private Comparators()

Simply invoke Comparators.verifyTransitivity(myComparator, myCollection) in front of the code that fails.

Give name and values to those submit buttons like:

    <td>
    <input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
    </td>
    <td>
    <input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
    </td>

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}

Init your autowired component in @PostConstruct method

@Component
public class TestClass {
   private static AutowiredTypeComponent component;

   @Autowired
   private AutowiredTypeComponent autowiredComponent;

   @PostConstruct
   private void init() {
      component = this.autowiredComponent;
   }

   public static void testMethod() {
      component.callTestMethod();
   }
}

Simple solution is here-

Below code uses HashMap as it will maintain keys and values. so here keys will be word and values will be count (occurance of a word in a given string).

public class WordOccurance 
{

 public static void main(String[] args) 
 {
    HashMap<String, Integer> hm = new HashMap<>();
    String str = "avinash pande avinash pande avinash";

    //split the word with white space       
    String words[] = str.split(" ");
    for (String word : words) 
    {   
        //If already added/present in hashmap then increment the count by 1
        if(hm.containsKey(word))    
        {           
            hm.put(word, hm.get(word)+1);
        }
        else //if not added earlier then add with count 1
        {
            hm.put(word, 1);
        }

    }
    //Iterate over the hashmap
    Set<Entry<String, Integer>> entry =  hm.entrySet();
    for (Entry<String, Integer> entry2 : entry) 
    {
        System.out.println(entry2.getKey() + "      "+entry2.getValue());
    }
}

}

YES, you can, because undefined is defined as undefined.

console.log(
   /*global.*/undefined === window['undefined'] &&
   /*global.*/undefined === (function(){})() &&
   window['undefined']  === (function(){})()
) //true

your case:

test("value1", undefined, "value2")

you can also create your own undefined variable:

Object.defineProperty(this, 'u', {value : undefined});
console.log(u); //undefined

This is what I used for my countdown clock:

</SCRIPT>
<center class="auto-style19" style="height: 31px">
<Font face="blacksmith" size="large"><strong>
<SCRIPT LANGUAGE="JavaScript">
var header = "You have <I><font color=red>" 
+ getDaysUntilICD10() + "</font></I>&nbsp; "
header += "days until ICD-10 starts!"
document.write(header)
</SCRIPT>

The HTML inside of my script worked, though I could not explain why.

string result = await resp.Content.ReadAsStringAsync(); List _Resp = JsonConvert.DeserializeObject<List>(result); //List _objList = new List((IEnumerable)_Resp);

            IList usll = _Resp.Select(a => a.lttsdata).ToList();
            // List<ListViewClass> _objList = new List<ListViewClass>((IEnumerable<ListViewClass>)_Resp);
            //IList usll = _objList.OrderBy(a=> a.ReqID).ToList();
            Lv.ItemsSource = usll;

The JVM will start with memory useage at the initial heap level. If the maxheap is higher, it will grow to the maxheap size as memory requirements exceed it's current memory.

So,

• -Xms512m -Xmx512m

JVM starts with 512 M, never resizes.

• -Xms64m -Xmx512m

JVM starts with 64M, grows (up to max ceiling of 512) if mem. requirements exceed 64.

I have tried all the suggested solutions but nothing worked.

I am using macOS Catalina 10.15.3

Go to /usr/local/

Select bin folder > Get Info

Add your user to Sharing & Permissions. Read & Write Permissions.

And go to terminal and run npm install -g @ionic/cli

It has helped me.

An interop calls something else, it's an interoperability assembly, so you're inter-operating with something...in this case Excel, the actual installed Excel.

In this case yes, it will fail to run because it depends on excel, you're just calling excel functions. If they don't have it installed...out of luck.

There are methods to generate without Excel, provided the 2007 file format is ok, here's a few:

• http://excelpackage.codeplex.com/
• http://simpleooxml.codeplex.com/

as I said though, this is the 2007 format, normally if anything, that's the deal-breaker.

Why not JSON.stringify and .includes()?

You can easily check if a JSON object includes a value by turning it into a string and checking the string.

console.log(JSON.stringify(JSONObject).includes("dog"))
--> true

Edit: make sure to check browser compatibility for .includes()

Answer from italo is very good! However let me refine it a little:

function isEllipsisActive(e) {
   var tolerance = 2; // In px. Depends on the font you are using
   return e.offsetWidth + tolerance < e.scrollWidth;
}

Cross browser compatibility

If, in fact, you try the above code and use console.log to print out the values of e.offsetWidth and e.scrollWidth, you will notice, on IE, that, even when you have no text truncation, a value difference of 1px or 2px is experienced.

So, depending on the font size you use, allow a certain tolerance!

I searched on the internet and found a simple jquery code to handle this problem. In my side, it was solved and worked on ie 9.

$("input[placeholder]").each(function () {
        var $this = $(this);
        if($this.val() == ""){
            $this.val($this.attr("placeholder")).focus(function(){
                if($this.val() == $this.attr("placeholder")) {
                    $this.val("");
                }
            }).blur(function(){
                if($this.val() == "") {
                    $this.val($this.attr("placeholder"));
                }
            });
        }
    });

A non-lodash way to solve this in a fairly readable and efficient manner:

function filterByKeys(obj, keys = []) {_x000D_
  const filtered = {}_x000D_
  keys.forEach(key => {_x000D_
    if (obj.hasOwnProperty(key)) {_x000D_
      filtered[key] = obj[key]_x000D_
    }_x000D_
  })_x000D_
  return filtered_x000D_
}_x000D_
_x000D_
const myObject = {_x000D_
  a: 1,_x000D_
  b: 'bananas',_x000D_
  d: null_x000D_
}_x000D_
_x000D_
const result = filterByKeys(myObject, ['a', 'd', 'e']) // {a: 1, d: null}_x000D_
console.log(result)

This answers what the OP should have asked, i.e. traverse a list comparing consecutive elements (excellent SilentGhost answer), yet generalized for any group (n-gram): 2, 3, ... n:

zip(*(l[start:] for start in range(0, n)))

Examples:

l = range(0, 4)  # [0, 1, 2, 3]

list(zip(*(l[start:] for start in range(0, 2)))) # == [(0, 1), (1, 2), (2, 3)]
list(zip(*(l[start:] for start in range(0, 3)))) # == [(0, 1, 2), (1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 4)))) # == [(0, 1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 5)))) # == []

Explanations:

• l[start:] generates a a list/generator starting from index start
• *list or *generator: passes all elements to the enclosing function zip as if it was written zip(elem1, elem2, ...)

Note:

AFAIK, this code is as lazy as it can be. Not tested.

I think you can find the answer you want in these two posts. They are mentioning Flash Builder, but essentially, the talk is about its Eclipse base.

Below are the 3 different ways provided by HTML to insert empty space

1. Type   to add a single space.
2. Type   to add 2 spaces.
3. Type   to add 4 spaces.

As a last resort, if all other suggestions fail, then backup all your data and do a factory reset.

Have more freedom using CATransition class.

It isn't limited to fading, but can do movements as well..

For example:

(don't forget to import QuartzCore)

CATransition *transition = [CATransition animation];
transition.type = kCATransitionPush;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.fillMode = kCAFillModeForwards;
transition.duration = 0.5;
transition.subtype = kCATransitionFromBottom;

[[self.tableView layer] addAnimation:transition forKey:@"UITableViewReloadDataAnimationKey"];

Change the type to match your needs, like kCATransitionFade etc.

Implementation in Swift:

let transition = CATransition()
transition.type = kCATransitionPush
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.fillMode = kCAFillModeForwards
transition.duration = 0.5
transition.subtype = kCATransitionFromTop
self.tableView.layer.addAnimation(transition, forKey: "UITableViewReloadDataAnimationKey")
// Update your data source here
self.tableView.reloadData()

Reference for CATransition

Swift 5:

let transition = CATransition()
transition.type = CATransitionType.push
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.fillMode = CAMediaTimingFillMode.forwards
transition.duration = 0.5
transition.subtype = CATransitionSubtype.fromTop
self.tableView.layer.add(transition, forKey: "UITableViewReloadDataAnimationKey")
// Update your data source here
self.tableView.reloadData()

RecordCount is what you want to use.

If Not temp_rst1.RecordCount > 0 ...

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

You can provide a file-like object to the stdin argument of subprocess.call().

The documentation for the Popen object applies here.

To capture the output, you should instead use subprocess.check_output(), which takes similar arguments. From the documentation:

>>> subprocess.check_output(
...     "ls non_existent_file; exit 0",
...     stderr=subprocess.STDOUT,
...     shell=True)
'ls: non_existent_file: No such file or directory\n'

It is also possible to use tidyr::replace_na.

    library(tidyr)
    df <- df %>% mutate_all(funs(replace_na(.,0)))

I had the same problem, but a slightly different solution was called for. The problem in this case was the class of the File Owner, rather than the class of the View. To set this, I had to click the "backwards play" icon in the lower left corner of the Interface Builder window, and options then appeared that isolated the characteristics of the File Owner, the First Responder, and the View. Clicking on the first one (a large transparent box), enabled me to then set its custom class as suggested above.

as answered above by: kcoppock and Joril

go here : https://github.com/android/platform_frameworks_base/tree/master/core/res/res/layout

just right click the layout file you want, then select 'Save As', save somewhere, then copy it in 'layout' folder in your android project(eclipse)...

you can see how the layout looks like :)

way to go...

If you are using an MSSQL Server 2008 and above, you can perform your SELECT query to return json by using the FOR JSON AUTO clause E.G

SELECT name, surname FROM users FOR JSON AUTO

Will return Json as

[{"name": "Jane","surname": "Doe" }, {"name": "Foo","surname": "Samantha" }, ..., {"name": "John", "surname": "boo" }]

You can use the following code to check if the file can be opened with exclusive access (that is, it is not opened by another application). If the file isn't closed, you could wait a few moments and check again until the file is closed and you can safely copy it.

You should still check if File.Copy fails, because another application may open the file between the moment you check the file and the moment you copy it.

public static bool IsFileClosed(string filename)
{
    try
    {
        using (var inputStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None))
        {
            return true;
        }
    }
    catch (IOException)
    {
        return false;
    }
}

How does the virtual keyword work?

Assume that Man is a base class, Indian is derived from man.

Class Man
{
 public: 
   virtual void do_work()
   {}
}

Class Indian : public Man
{
 public: 
   void do_work()
   {}
}

Declaring do_work() as virtual simply means: which do_work() to call will be determined ONLY at run-time.

Suppose I do,

Man *man;
man = new Indian();
man->do_work(); // Indian's do work is only called.

If virtual is not used, the same is statically determined or statically bound by the compiler, depending on what object is calling. So if an object of Man calls do_work(), Man's do_work() is called EVEN THOUGH IT POINTS TO AN INDIAN OBJECT

I believe that the top voted answer is misleading - Any method whether or not virtual can have an overridden implementation in the derived class. With specific reference to C++ the correct difference is run-time (when virtual is used) binding and compile-time (when virtual is not used but a method is overridden and a base pointer is pointed at a derived object) binding of associated functions.

There seems to be another misleading comment that says,

"Justin, 'pure virtual' is just a term (not a keyword, see my answer below) used to mean "this function cannot be implemented by the base class."

THIS IS WRONG! Purely virtual functions can also have a body AND CAN BE IMPLEMENTED! The truth is that an abstract class' pure virtual function can be called statically! Two very good authors are Bjarne Stroustrup and Stan Lippman.... because they wrote the language.

This works:

$category = $catrep->createQueryBuilder('cc')
        ->select('cc.categoryid')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->distinct()
        ->getQuery();

$categories = $category->getResult();

Edit for Symfony 3 & 4.

You should use ->groupBy('cc.categoryid') instead of ->distinct()

To my knowledge the only way to achieve this in a native select would be to use the unicode representations of the font. You'll have to apply the glyphicon font to the select and as such can't mix it with other fonts. However, glyphicons include regular characters, so you can add text. Unfortunately setting the font for individual options doesn't seem to be possible.

<select class="form-control glyphicon">
    <option value="">&#x2212; &#x2212; &#x2212; Hello</option>
    <option value="glyphicon-list-alt">&#xe032; Text</option>
</select>

Here's a list of the icons with their unicode:

http://glyphicons.bootstrapcheatsheets.com/

Set border: 1px solid black to make all sides equals and remove any kind of custom border (other than solid). Also, set box-shadow: none to remove any inset shadow applied to it.

right-click to your controller.java then properties and check if your text file is encoded with utf-8, if not this is your mistake.

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

You should use a Calendar instead:

Calendar start = Calendar.getInstance();
start.setTimeInMillis( timeStampValue.getTime() );

Webkit is a web browser rendering engine used by Safari and Chrome (among others, but these are the popular ones).

The -webkit prefix on CSS selectors are properties that only this engine is intended to process, very similar to -moz properties. Many of us are hoping this goes away, for example -webkit-border-radius will be replaced by the standard border-radius and you won't need multiple rules for the same thing for multiple browsers. This is really the result of "pre-specification" features that are intended to not interfere with the standard version when it comes about.

For your update:...no it's not related to IE really, IE at least before 9 uses a different rendering engine called Trident.

Add the @Configuration annotation in the RestTemplateSOMENAME which extends the RestTemplate class.

@Configuration         
public class RestTemplateClass extends RestTemplate {

}

Then in your controller class you can use the Autowired annotation as follows.

@Autowired   
RestTemplateClass restTemplate;

In XCode 7 you can update your bundle identifier by double clicking your target and changing the name.

Using Javascript, all you need is document.createElement and setAttribute.

var input = document.createElement("input");
input.setAttribute('type', 'text');

Then you can use appendChild to append the created element to the desired parent element.

var parent = document.getElementById("parentDiv");
parent.appendChild(input);

It will create your repository in the .git folder in the current directory.

Your textboxes are probably inside of panels or other containers, and not directly inside the form.

You need to recursively traverse the Controls collection of every child control.

For those using CloudFormation template. You can set AWS_DEFAULT_REGION environment variable using UserData and AWS::Region. For example,

MyInstance1:

                    echo "export AWS_DEFAULT_REGION=${AWS::Region}" >> /etc/profile

A function void f() compiled by a C compiler and a function with the same name void f() compiled by a C++ compiler are not the same function. If you wrote that function in C, and then you tried to call it from C++, then the linker would look for the C++ function and not find the C function.

extern "C" tells the C++ compiler that you have a function which was compiled by the C compiler. Once you tell it that it was compiled by the C compiler, the C++ compiler will know how to call it correctly.

It also allows the C++ compiler to compile a C++ function in such a way that the C compiler can call it. That function would officially be a C function, but since it is compiled by the C++ compiler, it can use all the C++ features and has all the C++ keywords.

One liner:

echo 'd *' | mail -N

To use String.concat, you need to replace your existing text, since the function does not act by reference.

var text ="";
for (var member in list) {
        text = text.concat(list[member]);
}

Of course, the join() or += suggestions offered by others will work fine as well.

If you're looking to print this in a page using django templates, then the following might be enough:

{{ birth_date|timesince }}

Your method needs to return a ActionResult type:

public ActionResult Index()
{
    //All we want to do is redirect to the class selection page
    return RedirectToAction("SelectClasses", "Registration");
}

It is only required if you aren't using the default values for version and encoding (which you are in that example).

In order to launch the current file with the respective venv, I added this to file launch.json:

 {
        "name": "Python: Current File",
        "type": "python",
        "request": "launch",
        "program": "${file}",
        "pythonPath": "${workspaceFolder}/FOO/DIR/venv/bin/python3"
    },

In the bin folder resides the source .../venv/bin/activate script which is regularly sourced when running from a regular terminal.

A simple JSF Url Prettyfier filter based in the steps of BalusC's answer. The filter forwards all the requests starting with the /ui path (supposing you've got all your xhtml files stored there) to the same path, but adding the xhtml suffix.

public class UrlPrettyfierFilter implements Filter {

    private static final String JSF_VIEW_ROOT_PATH = "/ui";

    private static final String JSF_VIEW_SUFFIX = ".xhtml";

    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpServletRequest = ((HttpServletRequest) request);
        String requestURI = httpServletRequest.getRequestURI();
        //Only process the paths starting with /ui, so as other requests get unprocessed. 
        //You can register the filter itself for /ui/* only, too
        if (requestURI.startsWith(JSF_VIEW_ROOT_PATH) 
                && !requestURI.contains(JSF_VIEW_SUFFIX)) {
            request.getRequestDispatcher(requestURI.concat(JSF_VIEW_SUFFIX))
                .forward(request,response);
        } else {
            chain.doFilter(httpServletRequest, response);
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}

Here is a pure MongoDB based solution for this problem which I just wrote for fun. It's effectively a server-side string-to-number parser which supports positive and negative numbers as well as decimals:

db.collection.aggregate({
    $addFields: {
        "moop": {
            $reduce: {
                "input": {
                    $map: { // split string into char array so we can loop over individual characters
                        "input": {
                            $range: [ 0, { $strLenCP: "$moop" } ] // using an array of all numbers from 0 to the length of the string
                        },
                        "in":{
                            $substrCP: [ "$moop", "$$this", 1 ] // return the nth character as the mapped value for the current index
                        }
                    }
                },
                "initialValue": { // initialize the parser with a 0 value
                    "n": 0, // the current number
                    "sign": 1, // used for positive/negative numbers
                    "div": null, // used for shifting on the right side of the decimal separator "."
                    "mult": 10 // used for shifting on the left side of the decimal separator "."
                }, // start with a zero
                "in": {
                    $let: {
                        "vars": {

I am certainly not advertising this as the bee's knees or anything and it might have severe performance implications for larger datasets over a client based solutions but there might be cases where it comes in handy...

The above pipeline will transform the following documents:

{ "moop": "12345" } --> { "moop": 12345 }

and

{ "moop": "123.45" } --> { "moop": 123.45 }

and

{ "moop": "-123.45" } --> { "moop": -123.45 }

and

{ "moop": "2018-01-03" } --> { "moop": 20180103.0 }

I've used most of the times the LIKE option and it works just fine. I just like to share one of my latest experiences where I used INSTR function. Regardless of the reasons that made me consider this options, what's important here is that the use is similar: instr(A, 'text 1') > 0 or instr(A, 'text 2') > 0 Another option could be: (instr(A, 'text 1') + instr(A, 'text 2')) > 0

I'd go with the LIKE '%text1%' OR LIKE '%text2%' option... if not hope this other option helps

You need to register the directory with Oracle. fopen takes the name of a directory object, not the path. For example:

(you may need to login as SYS to execute these)

CREATE DIRECTORY MY_DIR AS 'C:\';

GRANT READ ON DIRECTORY MY_DIR TO SCOTT;

Then, you can refer to it in the call to fopen:

execute sal_status('MY_DIR','vin1.txt');

Here's the official line on the problem (I couldn't find the latest, but I don't think the situation has changed for later versions of .net)

Take out the MONTHS from your case, and remove the brackets... like this:

CASE 
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

You can think of this as being equivalent to:

CASE TRUE
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

As per PHP Documentation,

What does thread safety mean when downloading PHP?

Thread Safety means that binary can work in a multithreaded webserver context, such as Apache 2 on Windows. Thread Safety works by creating a local storage copy in each thread, so that the data won't collide with another thread.

So what do I choose? If you choose to run PHP as a CGI binary, then you won't need thread safety, because the binary is invoked at each request. For multithreaded webservers, such as IIS5 and IIS6, you should use the threaded version of PHP.

Following Libraries are not thread safe. They are not recommended for use in a multi-threaded environment.

• SNMP (Unix)
• mSQL (Unix)
• IMAP (Win/Unix)
• Sybase-CT (Linux, libc5)

This is the fastest and the most readable way:

this.setState({...this.state.jasper, name: 'someothername'});

Even if this.state.jasper already contains a name property, the new name name: 'someothername' with be used.

Having said, I'd rather see developers build kick-ass apps that are well-designed and follow separation of concerns, than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework - Model-View-Whatever. Where Whatever stands for "whatever works for you".

Go to app.module.ts

import import { HttpClientModule } from '@angular/common/http';

AND

Add HttpClientModule under imports

should look like this

imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule,HttpClientModule]

The API doc for IllegalArgumentException:

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

From looking at how it is used in the JDK libraries, I would say:

• It seems like a defensive measure to complain about obviously bad input before the input can get into the works and cause something to fail halfway through with a nonsensical error message.

• It's used for cases where it would be too annoying to throw a checked exception (although it makes an appearance in the java.lang.reflect code, where concern about ridiculous levels of checked-exception-throwing is not otherwise apparent).

I would use IllegalArgumentException to do last ditch defensive argument checking for common utilities (trying to stay consistent with the JDK usage). Or where the expectation is that a bad argument is a programmer error, similar to an NullPointerException. I wouldn't use it to implement validation in business code. I certainly wouldn't use it for the email example.

There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.

Your code could look like this:

<script>
    var count = 1;
    function setColor(btn, color) {
        var property = document.getElementById(btn);
        if (count == 0) {
            property.style.backgroundColor = "#FFFFFF"
            count = 1;        
        }
        else {
            property.style.backgroundColor = "#7FFF00"
            count = 0;
        }
    }
</script>

Hope this helps.

Turn if off:

You can use error_reporting(); or put an @ in front of your fileopen().

function is_mobile_valid(string_or_number){
            var mobile=string_or_number;
            if(mobile.length!=10){
                return false;

            }
            intRegex = /[0-9 -()+]+$/;
            is_mobile=true;
            for ( var i=0; i < 10; i++) {
                if(intRegex.test(mobile[i]))
                     { 
                     continue;
                     }
                    else{
                        is_mobile=false;
                        break;
                    }
                 }
            return is_mobile;

}

You can just check by calling the function is_mobile_valid(your_string_of_mobile_number);

Another option is to get a ".pem" (public key) file for that particular server, and install it locally into the heart of your JRE's "cacerts" file (use the keytool helper application), then it will be able to download from that server without complaint, without compromising the entire SSL structure of your running JVM and enabling download from other unknown cert servers...

You might look at the code for the open source tool findimagedupes, though it appears to have been written in perl, so I can't say how easy it will be to parse...

Reading the findimagedupes page that I liked, I see that there is a C++ implementation of the same algorithm. Presumably this will be easier to understand.

And it appears you can also use gqview.

If you want to remove only leading and trailing whitespace (like PHP's trim) you can use .strip, but if you want to remove all whitespace, you can use .gsub(/\s+/, "") instead .

I faced the problem of gettng entire text from Text widget and following solution worked for me :

txt.get(1.0,END)

Where 1.0 means first line, zeroth character (ie before the first!) is the starting position and END is the ending position.

I am a beginner myself and I honestly couldn't find a satisfactory answer that I could understand or implement.

So here's an external link that I really helped me achieved what I wanted. It's very straight forward and easy to follow as well.

http://www.helloandroid.com/tutorials/how-display-custom-dialog-your-android-application

THIS WHAT I TRIED TO ACHIEVE WITH THE CODE:

I have a MainActivity that hosts a Fragment. I wanted a dialog to appear on top of the layout to ask for user input and then process the input accordingly. See a screenshot

Here's what the onCreateView of my fragment looks

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_home_activity, container, false);

    Button addTransactionBtn = rootView.findViewById(R.id.addTransactionBtn);

    addTransactionBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Dialog dialog = new Dialog(getActivity());
            dialog.setContentView(R.layout.dialog_trans);
            dialog.setTitle("Add an Expense");
            dialog.setCancelable(true);

            dialog.show();

        }
    });

I hope it will help you

Let me know if there's any confusion. :)

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

Use PHP's popen command, e.g.:

pclose(popen("start c:\wamp\bin\php.exe c:\wamp\www\script.php","r"));

This will create a child process and the script will excute in the background without waiting for output.

Ken had it right as well.

a css tag:

audio {

}

will get you some results. seems it doesnt want the player any height above or below 25px but the width can be shortened or lengthened to an extent.

this was good enough for me; see this example (warning, audio plays automatically): www.thenewyorkerdeliinc.com

I know it's a bit late but, Microsoft has made their Xaml.Behaviors open source and it's now much easier to use interactivity with just one namespace.

1. First add Microsoft.Xaml.Behaviors.Wpf Nuget packge to your project.
   https://www.nuget.org/packages/Microsoft.Xaml.Behaviors.Wpf/
2. add xmlns:behaviours="http://schemas.microsoft.com/xaml/behaviors" namespace to your xaml.

Then use it like this,

<Button Width="150" Style="{DynamicResource MaterialDesignRaisedDarkButton}">
   <behaviours:Interaction.Triggers>
       <behaviours:EventTrigger EventName="Click">
           <behaviours:InvokeCommandAction Command="{Binding OpenCommand}" PassEventArgsToCommand="True"/>
       </behaviours:EventTrigger>
    </behaviours:Interaction.Triggers>
    Open
</Button>

PassEventArgsToCommand="True" should be set as True and the RelayCommand that you implement can take RoutedEventArgs or objects as template. If you are using object as the parameter type just cast it to the appropriate event type.

The command will look something like this,

OpenCommand = new RelayCommand<object>(OnOpenClicked, (o) => { return true; });

The command method will look something like this,

private void OnOpenClicked(object parameter)
{
    Logger.Info(parameter?.GetType().Name);
}

The 'parameter' will be the Routed event object.

And the log incase you are curious,

2020-12-15 11:40:36.3600|INFO|MyApplication.ViewModels.MainWindowViewModel|RoutedEventArgs

As you can see the TypeName logged is RoutedEventArgs

RelayCommand impelmentation can be found here.

PS : You can bind to any event of any control. Like Closing event of Window and you will get the corresponding events.

Add a notifier in the viewWillAppear function

-(void)viewWillAppear:(BOOL)animated{
  [super viewWillAppear:animated];
  [[NSNotificationCenter defaultCenter] addObserver:self  selector:@selector(orientationChanged:)    name:UIDeviceOrientationDidChangeNotification  object:nil];
}

The orientation change notifies this function

- (void)orientationChanged:(NSNotification *)notification{
   [self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];
}

which in-turn calls this function where the moviePlayerController frame is orientation is handled

- (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {

    switch (orientation)
    {
        case UIInterfaceOrientationPortrait:
        case UIInterfaceOrientationPortraitUpsideDown:
        { 
        //load the portrait view    
        }

            break;
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
        {
        //load the landscape view 
        }
            break;
        case UIInterfaceOrientationUnknown:break;
    }
}

in viewDidDisappear remove the notification

-(void)viewDidDisappear:(BOOL)animated{
   [super viewDidDisappear:animated];
   [[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
}

I guess this is the fastest u can have changed the view as per orientation

I had mostly the same problem and ended up a a different solution that makes this type of problem trivial to query.

I have a table of sensor data (1 minute data from about 30 sensors)

SensorReadings->(timestamp,value,idSensor)

and I have a sensor table that has lots of mostly static stuff about the sensor but the relevant fields are these:

Sensors->(idSensor,Description,tvLastUpdate,tvLastValue,...)

The tvLastupdate and tvLastValue are set in a trigger on inserts to the SensorReadings table. I always have direct access to these values without needing to do any expensive queries. This does denormalize slightly. The query is trivial:

SELECT idSensor,Description,tvLastUpdate,tvLastValue 
FROM Sensors

I use this method for data that is queried often. In my case I have a sensor table, and a large event table, that have data coming in at the minute level AND dozens of machines are updating dashboards and graphs with that data. With my data scenario the trigger-and-cache method works well.

Another (easier - at least for me) way to do this is below.

install.packages("ggplot2movies")

data(movies, package="ggplot2movies")

rating_by_len = tapply(movies$length,
                       movies$rating,
                       mean)

plot(names(rating_by_len), rating_by_len, ylim=c(0, 200)
     ,xlab = "Rating", ylab = "Length", main="Average Rating by Movie Length", pch=21)

sds = tapply(movies$length, movies$rating, sd)
upper = rating_by_len + sds
lower = rating_by_len - sds
segments(x0=as.numeric(names(rating_by_len)), 
         y0=lower, 
         y1=upper)

Hope that helps.

Open a command prompt and type one of the following lines according to your Visual Studio version and Operating System Architecture :

VS 2008 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>

VS 2008 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>

VS 2010 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>

VS 2010 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>

VS 2012 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>

VS 2012 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>

VS 2015 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe" -T <assemblyname>

Note that for the versions VS2012+, sn.exe application isn't anymore in bin but in a sub-folder. Also, note that for 64bit you need to specify (x86) folder.

If you prefer to use Visual Studio command prompt, just type :

sn -T <assembly> 

where <assemblyname> is a full file path to the assembly you're interested in, surrounded by quotes if it has spaces.

You can add this as an external tool in VS, as shown here:

@blytung Has a nice function to replace that function

<?php
$url = "http://www.example.org/";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$contents = curl_exec($ch);
if (curl_errno($ch)) {
  echo curl_error($ch);
  echo "\n<br />";
  $contents = '';

If you are facing this issue in case of Sqlite then

. I think this is the problem with version of Sqlite,I had the same problem when I was using this versions of SqLite

Version 2.2.4:

After checking version here I changed the version then it worked.

No error after using this

Version 2.1.2:

you also use preg_replace_callback function . and this function is identical to its sibling preg_replace except for it can take a callback function which gives you more control on how you manipulate your output.

$str = "this is a   string";

echo preg_replace_callback(
        '/\s+/',
        function ($matches) {
            return "";
        },
        $str
      );

ECMAScript 6 introduced String.prototype.includes:

const string = "foo";_x000D_
const substring = "oo";_x000D_
_x000D_
console.log(string.includes(substring));

includes doesn’t have Internet Explorer support, though. In ECMAScript 5 or older environments, use String.prototype.indexOf, which returns -1 when a substring cannot be found:

var string = "foo";_x000D_
var substring = "oo";_x000D_
_x000D_
console.log(string.indexOf(substring) !== -1);

Try to surround strings (hoot, story, article) with quotes ':

<div ng-repeat = "data in comments">
    <div ng-if="data.type == 'hoot' ">
        //different template with hoot data
    </div>
    <div ng-if="data.type == 'story' ">
        //different template with story data
    </div>
    <div ng-if="data.type == 'article' ">
        //different template with article data
    </div> 
</div>

In c++ : before including class header that has a private function that you want test it

Use this code:

#define private public
#define protected public

12 years later for anyone having similar problems.

try:
    s.connect((address, '80'))
except:
    alert('failed' + address, 'down')

doesn't work because the port '80' is a string. Your port needs to be int.

try:
    s.connect((address, 80))

This should work. Not sure why even the best answer didnt see this.

You could use Directory.GetCurrentDirectory:

var path = Path.Combine(Directory.GetCurrentDirectory(), "\\fileName.txt");

Which will look for the file fileName.txt in the current directory of the application.

This is called ACF(Automatic Content Filter) in ckeditor.It remove all unnessary tag's What we are using in text content.Using this command in your config.js file should be turn off this ACK.

config.allowedContent = true;

The Eclipse (software) page on Wikipedia summarizes it pretty well:

Releases

Since 2006, the Eclipse Foundation has coordinated an annual Simultaneous Release. Each release includes the Eclipse Platform as well as a number of other Eclipse projects. Until the Galileo release, releases were named after the moons of the solar system.

So far, each Simultaneous Release has occurred at the end of June.

Release         Main Release   Platform version      Projects
Photon          27 June 2018     4.8
Oxygen          28 June 2017     4.7                 
Neon            22 June 2016     4.6                 
Mars            24 June 2015     4.5                 Mars Projects
Luna            25 June 2014     4.4                 Luna Projects
Kepler          26 June 2013     4.3                 Kepler Projects
Juno            27 June 2012     4.2                 Juno Projects
Indigo          22 June 2011     3.7                 Indigo projects
Helios          23 June 2010     3.6                 Helios projects
Galileo         24 June 2009     3.5                 Galileo projects
Ganymede        25 June 2008     3.4                 Ganymede projects
Europa          29 June 2007     3.3                 Europa projects
Callisto        30 June 2006     3.2                 Callisto projects
Eclipse 3.1     28 June 2005     3.1  
Eclipse 3.0     28 June 2004     3.0  

To summarize, Helios, Galileo, Ganymede, etc are just code names for versions of the Eclipse platform (personally, I'd prefer Eclipse to use traditional version numbers instead of code names, it would make things clearer and easier). My suggestion would be to use the latest version, i.e. Eclipse Oxygen (4.7) (in the original version of this answer, it said "Helios (3.6.1)").

On top of the "platform", Eclipse then distributes various Packages (i.e. the "platform" with a default set of plugins to achieve specialized tasks), such as Eclipse IDE for Java Developers, Eclipse IDE for Java EE Developers, Eclipse IDE for C/C++ Developers, etc (see this link for a comparison of their content).

To develop Java Desktop applications, the Helios release of Eclipse IDE for Java Developers should suffice (you can always install "additional plugins" if required).

Use a real dropdown menu instead: a list (ul, li) and links. Never misuse form elements as links.

Readers with screen readers usually scan through a automagically generated list of links – the’ll miss these important information. Many keyboard navigation systems (e.g. JAWS, Opera) offer different keyboard shortcuts for links and form elements.

If you still cannot drop the idea of a select don’t use the onchange handler at least. This is a real pain for keyboard users, it makes your third item nearly inaccessible.

I know your question does not specify if you are trying to open all a tags in a new window or only the external links.

But in case you only want external links to open in a new tab you can do this:

$( 'a[href^="http://"]' ).attr( 'target','_blank' )
$( 'a[href^="https://"]' ).attr( 'target','_blank' )

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

<script type="text/javascript" src="jquery.js"></script>          
<script type="text/javascript">
  $(document).ready(function() {
      $("#suburb").blur(function() {
          if ($(this).val() != '')
              $("#post_code").attr("disabled", "disabled");
          else
              $("#post_code").removeAttr("disabled");
      });

      $("#post_code").blur(function() {
          if ($(this).val() != '')
              $("#suburb").attr("disabled", "disabled");
          else
              $("#suburb").removeAttr("disabled");
      });
  });
</script>

You'll also need to add a value attribute to the first option under your select element:

<option value=""></option>

Here is a solution to deal with files, which may be used more frequently...

int convert(char *infile, char *outfile) {

char *source = NULL;
FILE *fp = fopen(infile, "r");
long bufsize;
if (fp != NULL) {
    /* Go to the end of the file. */
    if (fseek(fp, 0L, SEEK_END) == 0) {
        /* Get the size of the file. */
        bufsize = ftell(fp);
        if (bufsize == -1) { /* Error */ }

        /* Allocate our buffer to that size. */
        source = malloc(sizeof(char) * (bufsize + 1));

        /* Go back to the start of the file. */
        if (fseek(fp, 0L, SEEK_SET) != 0) { /* Error */ }

        /* Read the entire file into memory. */
        size_t newLen = fread(source, sizeof(char), bufsize, fp);
        if ( ferror( fp ) != 0 ) {
            fputs("Error reading file", stderr);
        } else {
            source[newLen++] = '\0'; /* Just to be safe. */
        }
    }
    fclose(fp);
}
     
int sourceLen = bufsize - 1;
int destLen = sourceLen/2;
unsigned char* dest = malloc(destLen);
short i;  
unsigned char highByte, lowByte;  
      
for (i = 0; i < sourceLen; i += 2)  
{  
        highByte = toupper(source[i]);  
        lowByte  = toupper(source[i + 1]);  
  
        if (highByte > 0x39)  
            highByte -= 0x37;  
        else  
            highByte -= 0x30;  
  
        if (lowByte > 0x39)  
            lowByte -= 0x37;  
        else  
            lowByte -= 0x30;  
  
        dest[i / 2] = (highByte << 4) | lowByte;  
}  
        

FILE *fop = fopen(outfile, "w");
if (fop == NULL) return 1;
fwrite(dest, 1, destLen, fop);
fclose(fop);
free(source);
free(dest);
return 0;
}  

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

In Windows 10 PC, it is saved at:

C:\Users\<user>\.gradle\caches\modules-2\files-2.1\

The difference is that

window.location = document.URL;

will not reload the page if there is a hash (#) in the URL (with or without something after it), whereas

window.location.reload();

will reload the page.

 getSupportActionBar().setTitle("Your Title");

Starting in Python 3.9, the operator | creates a new dictionary with the merged keys and values from two dictionaries:

# d1 = { 'a': 1, 'b': 2 }
# d2 = { 'b': 1, 'c': 3 }
d3 = d2 | d1
# d3: {'b': 2, 'c': 3, 'a': 1}

This:

Creates a new dictionary d3 with the merged keys and values of d2 and d1. The values of d1 take priority when d2 and d1 share keys.

Also note the |= operator which modifies d2 by merging d1 in, with priority on d1 values:

# d1 = { 'a': 1, 'b': 2 }
# d2 = { 'b': 1, 'c': 3 }
d2 |= d1
# d2: {'b': 2, 'c': 3, 'a': 1}

?

No. You have to use is null and is not null in HQL.

mimetype headers are recognised by the browser for the purpose of a (fast) possible identifying a handler to use the downloaded file as target, for example, PDF would be downloaded and your Adobe Reader program would be executed with the path of the PDF file as an argument,

If your needs are to write a browser extension to handle your downloaded file, through your operation-system, or you simply want to make you project a more 'professional looking' go ahead and select a unique mimetype for you to use, it would make no difference since the operation-system would have no handle to open it with (some browsers has few bundled-plugins, for example new Google Chrome versions has a built-in PDF-reader),

if you want to make sure the file would be downloaded have a look at this answer: https://stackoverflow.com/a/34758866/257319

if you want to make your file type especially organised, it might be worth adding a few letters in the first few bytes of the file, for example, every JPG has this at it's file start:

if you can afford a jump of 4 or 8 bytes it could be very helpful for you in the rest of the way

:)

Your where clause should have worked. I am at a loss as to why it didn't. Let me show you how I would have figured out the problem with the where clause as it might help you for the future.

When I create triggers, I start at the query window by creating a temp table called #inserted (and or #deleted) with all the columns of the table. Then I popultae it with typical values (Always multiple records and I try to hit the test cases in the values)

Then I write my triggers logic and I can test without it actually being in a trigger. In a case like your where clause not doing what was expected, I could easily test by commenting out the insert to see what the select was returning. I would then probably be easily able to see what the problem was. I assure you that where clasues do work in triggers if they are written correctly.

Once I know that the code works properly for all the cases, I global replace #inserted with inserted and add the create trigger code around it and voila, a tested trigger.

AS I said in a comment, I have a concern that the solution you picked will not work properly in a multiple record insert or update. Triggers should always be written to account for that as you cannot predict if and when they will happen (and they do happen eventually to pretty much every table.)

It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1 is null or ConfigurationManager.AppSettings.Get("Url") is returning null.

The full paramiko distribution ships with a lot of good demos.

In the demos subdirectory, demo.py and interactive.py have full interactive TTY examples which would probably be overkill for your situation.

In your example above ssh_stdin acts like a standard Python file object, so ssh_stdin.write should work so long as the channel is still open.

I've never needed to write to stdin, but the docs suggest that a channel is closed as soon as a command exits, so using the standard stdin.write method to send a password up probably won't work. There are lower level paramiko commands on the channel itself that give you more control - see how the SSHClient.exec_command method is implemented for all the gory details.

String formatting, using the new-style .format() method (with the defaults .format() provides):

 '{}{}'.format(s, i)

Or the older, but "still sticking around", %-formatting:

 '%s%d' %(s, i)

In both examples above there's no space between the two items concatenated. If space is needed, it can simply be added in the format strings.

These provide a lot of control and flexibility about how to concatenate items, the space between them etc. For details about format specifications see this.

Here a CSS animation fork of jezzipin's Solution, to seperate code from styling.

JS:

$(window).on("scroll touchmove", function () {
  $('#header_nav').toggleClass('tiny', $(document).scrollTop() > 0);
});

CSS:

.header {
  width:100%;
  height:100px;
  background: #26b;
  color: #fff;
  position:fixed;
  top:0;
  left:0;
  transition: height 500ms, background 500ms;
}
.header.tiny {
  height:40px;
  background: #aaa;
}

http://jsfiddle.net/sinky/S8Fnq/

On scroll/touchmove the css class "tiny" is set to "#header_nav" if "$(document).scrollTop()" is greater than 0.

CSS transition attribute animates the "height" and "background" attribute nicely.

Minimal runnable C POSIX reproduction example

I recommend understanding the underlying API to better see what is going on.

sleep.c

#define _XOPEN_SOURCE 700
#include <unistd.h>

int main(void) {
    sleep(10000);
}

busy.c

#define _XOPEN_SOURCE 700
#include <assert.h>
#include <errno.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>

int main(void) {
    int ret = open("sleep.out", O_WRONLY|O_TRUNC);
    assert(errno == ETXTBSY);
    perror("");
    assert(ret == -1);
}

Compile and run:

gcc -std=c99 -o sleep.out ./sleep.c
gcc -std=c99 -o busy.out ./busy.c
./sleep.out &
./busy.out 

busy.out passes the asserts, and perror outputs:

Text file busy

so we deduce that the message is hardcoded in glibc itself.

Alternatively:

echo asdf > sleep.out

makes Bash output:

-bash: sleep.out: Text file busy

For a more complex application, you can also observe it with strace:

strace ./busy.out

which contains:

openat(AT_FDCWD, "sleep.out", O_WRONLY) = -1 ETXTBSY (Text file busy)

Tested on Ubuntu 18.04, Linux kernel 4.15.0.

The error does not happen if you unlink first

notbusy.c

#define _XOPEN_SOURCE 700
#include <assert.h>
#include <errno.h>
#include <fcntl.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int main(void) {
    assert(unlink("sleep.out") == 0);
    assert(open("sleep.out", O_WRONLY|O_CREAT) != -1);
}

Then compile and run analogously to the above, and those asserts pass.

This explains why it works for certain programs but not others. E.g. if you do:

gcc -std=c99 -o sleep.out ./sleep.c
./sleep.out &
gcc -std=c99 -o sleep.out ./sleep.c

that does not generate an error, even though the second gcc call is writing to sleep.out.

A quick strace shows that GCC first unlinks before writing:

 strace -f gcc -std=c99 -o sleep.out ./sleep.c |& grep sleep.out

contains:

[pid  3992] unlink("sleep.out")         = 0
[pid  3992] openat(AT_FDCWD, "sleep.out", O_RDWR|O_CREAT|O_TRUNC, 0666) = 3

The reason it does not fail is that when you unlink and re-write the file, it creates a new inode, and keeps a temporary dangling inode for the running executable file.

But if you just write without unlink, then it tries to write to the same protected inode as the running executable.

sysdeps/mach/hurd/bits/errno.h:62:  ETXTBSY                        = 0x4000001a,        /* Text file busy */

and a manual hit in manual/errno.texi:

@deftypevr Macro int ETXTBSY
@standards{BSD, errno.h}
@errno{ETXTBSY, 26, Text file busy}
An attempt to execute a file that is currently open for writing, or
write to a file that is currently being executed.  Often using a
debugger to run a program is considered having it open for writing and
will cause this error.  (The name stands for ``text file busy''.)  This
is not an error on @gnuhurdsystems{}; the text is copied as necessary.
@end deftypevr

I was importing also some projects from VS2010 to VS 2012. I had the same errors. The errors disappeared when I set back Properties > Config. Properties > General > Platform Toolset to v100 (VS2010). That might not be the correct approach, however.

Check out James Padolsey's animateToSelector

Intro: This jQuery plugin will allow you to animate any element to styles specified in your stylesheet. All you have to do is pass a selector and the plugin will look for that selector in your StyleSheet and will then apply it as an animation.

If you're desperate (like i was) for tooltips on checkboxes, textboxes and the like, then here is my hackey workaround:

$('input:disabled, button:disabled').after(function (e) {
    d = $("<div>");
    i = $(this);
    d.css({
        height: i.outerHeight(),
        width: i.outerWidth(),
        position: "absolute",
    })
    d.css(i.offset());
    d.attr("title", i.attr("title"));
    d.tooltip();
    return d;
});

Working examples: http://jsfiddle.net/WB6bM/11/

For what its worth, I believe tooltips on disabled form elements is very important to the UX. If you're preventing somebody from doing something, you should tell them why.

This https://github.com/rails/strong_parameters seems like the relevant section of the docs:

The permitted scalar types are String, Symbol, NilClass, Numeric, TrueClass, FalseClass, Date, Time, DateTime, StringIO, IO, ActionDispatch::Http::UploadedFile and Rack::Test::UploadedFile.

To declare that the value in params must be an array of permitted scalar values map the key to an empty array:

params.permit(:id => [])

In my app, the category_ids are passed to the create action in an array

"category_ids"=>["", "2"],

Therefore, when declaring strong parameters, I explicitly set category_ids to be an array

params.require(:question).permit(:question_details, :question_content, :user_id, :accepted_answer_id, :province_id, :city, :category_ids => [])

Works perfectly now!

(IMPORTANT: As @Lenart notes in the comments, the array declarations must be at the end of the attributes list, otherwise you'll get a syntax error.)

Define is evaluated before compilation by the pre-processor, while variables are referenced at run-time. This means you control how your application is built (not how it runs)

Here are a couple examples that use define which cannot be replaced by a variable:

1. #define min(i, j) (((i) < (j)) ? (i) : (j))
   note this is evaluated by the pre-processor, not during runtime

2. http://msdn.microsoft.com/en-us/library/8fskxacy.aspx

I'm afraid that most voted solution (https://stackoverflow.com/a/19271434/3283279) is not working properly. The fourth test case (var_dump(validateDate('2012-2-25')); // false) is wrong. The date is correct, because it corresponds to the format - the m allows a month with or without leading zero (see: http://php.net/manual/en/datetime.createfromformat.php). Therefore a date 2012-2-25 is in format Y-m-d and the test case must be true not false.

I believe that better solution is to test possible error as follows:

function validateDate($date, $format = 'Y-m-d') {
    DateTime::createFromFormat($format, $date);
    $errors = DateTime::getLastErrors();

    return $errors['warning_count'] === 0 && $errors['error_count'] === 0;
}

A possible workaround for the page title:

• Provide a print button,
• catch the onclick event,
• use javascript to change the page title,
• then execute the print command via javascript as well.

document.title = "Print page title"; window.print();

This should work in every browser.

Usually, the correct way of updating certain fields in one or more model instances is to use the update() method on the respective queryset. Then you do something like this:

affected_surveys = Survey.objects.filter(
    # restrict your queryset by whatever fits you
    # ...
    ).update(active=True)

This way, you don't need to call save() on your model anymore because it gets saved automatically. Also, the update() method returns the number of survey instances that were affected by your update.

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

It is not a compilation error at all! You can import a default package to a default package class only.

If you do so for another package, then it shall be a compilation error.

I created a function to check if times in an array overlap somehow:

    /**
     * Function to check if there are overlapping times in an array of \DateTime objects.
     *
     * @param $ranges
     *
     * @return \DateTime[]|bool
     */
    public function timesOverlap($ranges) {
        foreach ($ranges as $k1 => $t1) {
            foreach ($ranges as $k2 => $t2) {
                if ($k1 != $k2) {
                    /* @var \DateTime[] $t1 */
                    /* @var \DateTime[] $t2 */
                    $a = $t1[0]->getTimestamp();
                    $b = $t1[1]->getTimestamp();
                    $c = $t2[0]->getTimestamp();
                    $d = $t2[1]->getTimestamp();

                    if (($c >= $a && $c <= $b) || $d >= $a && $d <= $b) {
                        return true;
                    }
                }
            }
        }

        return false;
    }

I have done it the following way. Seems inefficient but I had no other way in my mind:

@login_required
def list_track(request):

usergroup = request.user.groups.values_list('name', flat=True).first()
if usergroup in 'appAdmin':
    tracks = QuestionTrack.objects.order_by('pk')
    return render(request, 'cmit/appadmin/list_track.html', {'tracks': tracks})

else:
    return HttpResponseRedirect('/cmit/loggedin')

It is possible! Yes

In many cases, you might want to use XAMPP with a different PHP version than the one that comes preinstalled. You might do this to get the benefits of a newer version of PHP, or to reproduce bugs using an earlier version of PHP.

To use a different version of PHP with XAMPP, follow these steps:

1. Download a binary build of the PHP version that you wish to use from the PHP website, and extract the contents of the compressed archive file to your XAMPP installation directory (usually, C:\xampp). Ensure that you give it a different directory name to avoid overwriting the existing PHP version. For example, in this tutorial, we’ll call the new directory C:\xampp\php5-6-0. NOTE : Ensure that the PHP build you download matches the Apache build (VC9 or VC11) in your XAMPP platform.

2. Within the new directory, rename the php.ini-development file to php.ini. If you prefer to use production settings, you could instead rename the php.ini-production file to php.ini.

3. Edit the httpd-xampp.conf file in the apache\conf\extra\ subdirectory of your XAMPP installation directory. Within this file, search for all instances of the old PHP directory path and replace them with the path to the new PHP directory created in Step 1. In particular, be sure to change the lines

    LoadFile "/xampp/php/php5ts.dll"
    LoadFile "/xampp/php/libpq.dll"
    LoadModule php5_module "/xampp/php/php5apache2_4.dll"

to

    LoadFile "/xampp/php5-6-0/php5ts.dll"
    LoadFile "/xampp/php5-6-0/libpq.dll"
    LoadModule php5_module "/xampp/php5-6-0/php5apache2_4.dll"

NOTE : Remember to adjust the file and directory paths above to reflect valid paths on your system.

4. Restart your Apache server through the XAMPP control panel for your changes to take effect. The new version of PHP should now be active. To verify this, browse to the URL http://localhost/xampp/phpinfo.php, which displays the output of the phpinfo() command, and check the version number at the top of the page.

This is built from Álvaro González's answer and How to increase IDE memory limit in IntelliJ IDEA on Mac?

Go to Help > Edit Custom Properties

Add:

idea.max.intellisense.filesize=999999

Restart the IDE.

It's notable to understand that if you'd like to conditionally add attributes you can also add a dynamic declaration:

<input v-bind="attrs" />

where attrs is declared as an object:

data() {
    return {
        attrs: {
            required: true,
            type: "text"
        }
    }
}

Which will result in:

<input required type="text"/>

Ideal in cases with multiple attributes.

This is not the correct usage of the System.Threading.Timer. When you instantiate the Timer, you should almost always do the following:

_timer = new Timer( Callback, null, TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite );

This will instruct the timer to tick only once when the interval has elapsed. Then in your Callback function you Change the timer once the work has completed, not before. Example:

private void Callback( Object state )
{
    // Long running operation
   _timer.Change( TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite );
}

Thus there is no need for locking mechanisms because there is no concurrency. The timer will fire the next callback after the next interval has elapsed + the time of the long running operation.

If you need to run your timer at exactly N milliseconds, then I suggest you measure the time of the long running operation using Stopwatch and then call the Change method appropriately:

private void Callback( Object state )
{
   Stopwatch watch = new Stopwatch();

   watch.Start();
   // Long running operation

   _timer.Change( Math.Max( 0, TIME_INTERVAL_IN_MILLISECONDS - watch.ElapsedMilliseconds ), Timeout.Infinite );
}

I strongly encourage anyone doing .NET and is using the CLR who hasn't read Jeffrey Richter's book - CLR via C#, to read is as soon as possible. Timers and thread pools are explained in great details there.

The answer probably depends on what format your date is in, but here is an example using the Date class:

dt <- as.Date("2010/02/10")
new.dt <- dt - as.difftime(2, unit="days")

You can even play with different units like weeks.

Update

The procedure presented below gives an example of parsing XML with VBA using the XML DOM objects. Code is based on a beginners guide of the XML DOM.

Public Sub LoadDocument()
    Dim xDoc As MSXML.DOMDocument
    Set xDoc = New MSXML.DOMDocument
    xDoc.validateOnParse = False
    If xDoc.Load("C:\My Documents\sample.xml") Then
        ' The document loaded successfully.
        ' Now do something intersting.
        DisplayNode xDoc.childNodes, 0
    Else
        ' The document failed to load.
        ' See the previous listing for error information.
    End If
End Sub

Public Sub DisplayNode(ByRef Nodes As MSXML.IXMLDOMNodeList, _
   ByVal Indent As Integer)

   Dim xNode As MSXML.IXMLDOMNode
   Indent = Indent + 2

   For Each xNode In Nodes
      If xNode.nodeType = NODE_TEXT Then
         Debug.Print Space$(Indent) & xNode.parentNode.nodeName & _
            ":" & xNode.nodeValue
      End If

      If xNode.hasChildNodes Then
         DisplayNode xNode.childNodes, Indent
      End If
   Next xNode
End Sub

Nota Bene - This initial answer shows the simplest possible thing I could imagine (at the time I was working on a very specific issue) . Naturally using the XML facilities built into the VBA XML Dom would be much better. See the updates above.

Original Response

I know this is a very old post but I wanted to share my simple solution to this complicated question. Primarily I've used basic string functions to access the xml data.

This assumes you have some xml data (in the temp variable) that has been returned within a VBA function. Interestingly enough one can also see how I am linking to an xml web service to retrieve the value. The function shown in the image also takes a lookup value because this Excel VBA function can be accessed from within a cell using = FunctionName(value1, value2) to return values via the web service into a spreadsheet.

openTag = ""
closeTag = "" 

' Locate the position of the enclosing tags
startPos = InStr(1, temp, openTag)
endPos = InStr(1, temp, closeTag)
startTagPos = InStr(startPos, temp, ">") + 1
' Parse xml for returned value
Data = Mid(temp, startTagPos, endPos - startTagPos)

You can add a wrapper around promise functionality to return an Observable to observer.

• Creating a Lazy Observable using defer() operator which allows you to create the Observable only when the Observer subscribes.

import { of, Observable, defer } from 'rxjs'; 
import { map } from 'rxjs/operators';


function getTodos$(): Observable<any> {
  return defer(()=>{
    return fetch('https://jsonplaceholder.typicode.com/todos/1')
      .then(response => response.json())
      .then(json => {
        return json;
      })
  });
}

getTodos$().
 subscribe(
   (next)=>{
     console.log('Data is:', next);
   }
)

SELECT DATENAME(DW,CONVERT(VARCHAR(20),GETDATE(),101))

What causes runtime error 380? Attempting to set a property of an object or control to a value that is not allowed. Look through the code that runs when your search form loads (Form_Load etc.) for any code that sets a property to something that depends on runtime values.

My other advice is to add some error handling and some logging to track down the exact line that is causing the error.

• Logging Sprinkle statements through the code that say "Got to X", "Got to Y", etc. Use these to find the exact location of the error. You can write to a text file or the event log or use OutputDebugString.
• Error handling Here's how to get a stack trace for the error. Add an error handler to every routine that might be involved, like this code below. The essential free tool MZTools can do this automatically. You could also use Erl to report line numbers and find the exact line - MZTools can automatically put in line numbers for you.

_

 On Error Goto Handler
   <routine contents>   
 Handler: 
   Err.Raise Err.Number, "(function_name)->" & Err.source, Err.Description 

Either enter absolute paths or relative paths.

For example the first one below uses absolute paths :

(this is from inside the folder which contains the repository and the backup as subfolders. also remember that the backup folder is not modified if it already contains anything. and if it is not present, a new folder will be created )

~/git$ git clone --no-hardlinks ~/git/git_test1/   ~/git/bkp_repos/

The following uses relative paths :

~/git$ git clone --no-hardlinks git_test1/   bkp_repos2/

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

Change your javascript to:

var input = document.getElementById('userInput').value;

This will get the value that has been types into the text box, not a DOM object

I have a similar problem (at least I think it is similar). In one of the replies here the solution is as follows:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

That WHERE clause I would like to be:

WHERE B.tag = A.<col_name>

or, in my specific case:

WHERE B.val BETWEEN A.val1 AND A.val2

More detailed:

Table A carries status information of a fleet of equipment. Each status record carries with it a start and stop time of that status. Table B carries regularly recorded, timestamped data about the equipment, which I want to extract for the duration of the period indicated in table A.

repair table myschema.mytable;

using str.replace(regex, $1);:

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;

if (str.match(regex)) {
    str = str.replace(regex, "$1" + "1" + "$2");
}

Edit: adaptation regarding the comment

Try this :

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id()); 
            echo "<b>".$_product->get_title().'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
        } 
?>

To get Product Image and Regular & Sale Price:

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id() );
            //product image
            $getProductDetail = wc_get_product( $values['product_id'] );
            echo $getProductDetail->get_image(); // accepts 2 arguments ( size, attr )

            echo "<b>".$_product->get_title() .'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
            /*Regular Price and Sale Price*/
            echo "Regular Price: ".get_post_meta($values['product_id'] , '_regular_price', true)."<br>";
            echo "Sale Price: ".get_post_meta($values['product_id'] , '_sale_price', true)."<br>";
        }
?>

In case someone is still searching for a query to display the difference in hr min and sec format: (This will display the difference in this format: 2 hr 20 min 22 secs)

SELECT
CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ' hrs ' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20)) + ' mins' +          CAST(DATEDIFF(second, StartDateTime, EndDateTime)% 60 as nvarchar(20))  + ' secs'

OR can be in the format as in the question:

CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ':' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20))

This code will help you, and it's fairly self-explanatory:

#include <stdio.h>      /* Standard Library of Input and Output */
#include <complex.h>    /* Standard Library of Complex Numbers */

int main() {

    double complex z1 = 1.0 + 3.0 * I;
    double complex z2 = 1.0 - 4.0 * I;

    printf("Working with complex numbers:\n\v");

    printf("Starting values: Z1 = %.2f + %.2fi\tZ2 = %.2f %+.2fi\n", creal(z1), cimag(z1), creal(z2), cimag(z2));

    double complex sum = z1 + z2;
    printf("The sum: Z1 + Z2 = %.2f %+.2fi\n", creal(sum), cimag(sum));

    double complex difference = z1 - z2;
    printf("The difference: Z1 - Z2 = %.2f %+.2fi\n", creal(difference), cimag(difference));

    double complex product = z1 * z2;
    printf("The product: Z1 x Z2 = %.2f %+.2fi\n", creal(product), cimag(product));

    double complex quotient = z1 / z2;
    printf("The quotient: Z1 / Z2 = %.2f %+.2fi\n", creal(quotient), cimag(quotient));

    double complex conjugate = conj(z1);
    printf("The conjugate of Z1 = %.2f %+.2fi\n", creal(conjugate), cimag(conjugate));

    return 0;
}

  with:

creal(z1): get the real part (for float crealf(z1), for long double creall(z1))

cimag(z1): get the imaginary part (for float cimagf(z1), for long double cimagl(z1))

Another important point to remember when working with complex numbers is that functions like cos(), exp() and sqrt() must be replaced with their complex forms, e.g. ccos(), cexp(), csqrt().

What you need is named array. I wanted to write the following code:

int[] n = new int[4];

for(int i=1;i<4;i++)
{
    n[i] = 5;
}

In Android Studio, Gradle is used for building our android application projects, hence playing the role of a build system. Before Android Studio, in Eclipse we used to compile and build the applications using command line tool which was soon taken over by GUI based steps to build and run Android Applications in eclipse using ANT. Every android application development tool has to compile resources, java source code, external libraries and combine them into a final APK.

Gradle is a build system, which is responsible for code compilation, testing, deployment and conversion of the code into .dex files and hence running the app on the device.

As Android Studio comes with Gradle system pre-installed, there is no need to install additional runtime softwares to build our project. Whenever you click on button in android studio, a gradle task automatically triggers and starts building the project and after gradle completes its task, app starts running in AVD or in the connected device.

A build system like Gradle is not a compiler, linker etc, but it controls and supervises the operation of compilation, linking of files, running test cases, and eventually bundling the code into an apk file for your Android Application.

There are two build.gradle files for every android studio project of which, one is for application and other is for project level(module level) build files.

In the build process, the compiler takes the source code, resources, external libraries JAR files and AndroidManifest.xml(which contains the meta-data about the application) and convert them into .dex(Dalvik Executable files) files, which includes bytecode. That bytecode is supported by all android devices to run your app. Then APK Manager combines the .dex files and all other resources into single apk file. APK Packager signs debug or release apk using respective debug or release keystore.

Debug apk is generally used for testing purpose or we can say that it is used at development stage only. When your app is complete with desired features and you are ready to publish your application for external use then you require a Release apk signed using a release keystore.

Now lets shed some light on the gradle files.

setting.gradle The setting.gradle(Gradle setting) file is used to specify all the modules used in your app.

build.gradle (project level) The Top level (module) build.gradle file is project level build file, which defines build configurations at project level. This file applies configurations to all the modules in android application project.

build.gradle (application level) The Application level build.gradle file is located in each module of the android project. This file includes your package name as applicationID, version name(apk version), version code, minimum and target sdk for a specific application module. When you are including external libraries(not the jar files) then you need to mention it in the app level gradle file to include them in your project as dependencies of the application.

Note: If a certain application is developed in variations for individual modules like, Smart Phone, Tablet or TV then separate gradle files must to be created for all. You can even start your gradle system through command line tool. Following commands are used for it:

./gradlew build - (build project)
./gradlew clean build - (build project complete scratch)
./gradlew clean build - (run the test)
./gradlew wrapper - (to see all the available tasks)

This is the current, literally official way to set Chrome policies: https://support.google.com/chrome/a/answer/187202?hl=en

The Windows and Linux templates, as well as common policy documentation for all operating systems, can be found here: https://dl.google.com/dl/edgedl/chrome/policy/policy_templates.zip (Zip file of Google Chrome templates and documentation)

Instructions for Windows (with my additions):

Open the ADM or ADMX template you downloaded:

• Extract "chrome.adm" in the language of your choice from the "policy_templates.zip" downloaded earlier (e.g. "policy_templates.zip\windows\adm\en-US\chrome.adm").
• Navigate to Start > Run: gpedit.msc.
• Navigate to Local Computer Policy > Computer / User Configuration > Administrative Templates.
• Right-click Administrative Templates, and select Add/Remove Templates.
• Add the "chrome.adm" template via the dialog.
• Once complete, Classic Administrative Templates (ADM) / Google / Google Chrome folder will appear under Administrative Templates.
• No matter whether you add the template under Computer Configuration or User Configuration, the settings will appear in both places, so you can configure Chrome at a machine or a user level.

Once you're done with this, continue from step 5 of Antony Hatchkins' answer. After you have added the extension ID(s), you can check that the policy is working in Chrome by opening chrome://policy (search for ExtensionInstallWhitelist).

This problem could be solved as mentioned using the .on on jQuery 1.7+ versions.

Unfortunately, this didn't work within my code (and I have 1.11) so I used:

$('body').delegate('.logout-link','click',function() {

http://api.jquery.com/delegate/

As of jQuery 3.0, .delegate() has been deprecated. It was superseded by the .on() method since jQuery 1.7, so its use was already discouraged. For earlier versions, however, it remains the most effective means to use event delegation. More information on event binding and delegation is in the .on() method. In general, these are the equivalent templates for the two methods:

// jQuery 1.4.3+
$( elements ).delegate( selector, events, data, handler );
// jQuery 1.7+
$( elements ).on( events, selector, data, handler );

I had the problem not able to load jar file in libs folder in Android Studio. If you have added JAR file in libs folder, then just open build.gradle file and save it without editing anything else. If you have added this line

compile fileTree(dir: 'libs', include: ['*.jar'])

save it and clean the project .. In next build time Android Studio will load the JAR file.

Hope this helps.

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

Look at the google gson library. It provides a rich api for dealing with this and is very straightforward to use.

I think that it's better to use simply str_replace, like the manual says:

If you don't need fancy replacing rules (like regular expressions), you should always use this function instead of ereg_replace() or preg_replace().

<?
$badUrl = "http://www.site.com/backend.php?/c=crud&m=index&t=care";
$goodUrl = str_replace('?/', '?', $badUrl);

You can try to search in preferences (android studio IDE > preferences). In aptana studio it works like this making smaller: CMD and -, use CMD shift and =. Works?

You can use VLOOKUP.

Assuming those are in columns A and B in Sheet1 and Sheet2 each, 22350 is in cell A2 of Sheet1, you can use:

=VLOOKUP(A2, Sheet2!A:B, 2, 0)

This will return you #N/A if there are no matches. Drag/Fill/Copy&Paste the formula to the bottom of your table and that should do it.

Just had similar problem in Eclipse fixed with:

rightclick on project->Properties->Deployment Assembly->add Maven Dependencies

something kicked it out before, while I was editing my pom.xml

I had all needed jar files, taglib uri and web.xml was ok

log in as root user:

sudo su

password:

then go and do what you want to do in var/www

file = '/path/to/file_to_be_read.txt'
with open(file) as f:
    print f.readlines()[26]
    print f.readlines()[30]

Using the with statement, this opens the file, prints lines 26 and 30, then closes the file. Simple!

The following command will create a copy in a new window. So you can continue see both original file and the new file.

Jeffrey L Whitledge is right. Your `dataList´-Object itself is null.

There is also another problem with your code: You are using the ref-keyword, which means the argument data cannot be null! The MSDN says:

An argument passed to a ref parameter must first be initialized. This differs from out, whose arguments do not have to be explicitly initialized before they are passed

It's also not a good idea to use generics with the type `Object´. Generics should avoid boxing/unboxing and also ensure type safety. If you want a common type make your method generic. Finally your code should look like this:

public class Foo<T> where T : MyTypeOrInterface {

      public List<T> dataList = new List<T>();

      public bool AddData(ref T data) {
        bool success = false;
        try {
          dataList.Add(data);                   
          success = doOtherStuff(data);
        } catch (Exception e) {
          throw new Exception(e.ToString());
        }
        return success;
      }

      private bool doOtherStuff(T data) {
        //...
      }
    }

you are calling a script file not a command so you have to use -file eg :

powershell -executionPolicy bypass -noexit -file "c:\temp\test.ps1" "c:\test with space"

for PS V2

powershell.exe -noexit &'c:\my scripts\test.ps1'

Here is a simple snippet that sorts a javascript representation of a Json.

function isObject(v) {
    return '[object Object]' === Object.prototype.toString.call(v);
};

JSON.sort = function(o) {
if (Array.isArray(o)) {
        return o.sort().map(JSON.sort);
    } else if (isObject(o)) {
        return Object
            .keys(o)
        .sort()
            .reduce(function(a, k) {
                a[k] = JSON.sort(o[k]);

                return a;
            }, {});
    }

    return o;
}

It can be used as follows:

JSON.sort({
    c: {
        c3: null,
        c1: undefined,
        c2: [3, 2, 1, 0],
    },
    a: 0,
    b: 'Fun'
});

That will output:

{
  a: 0,
  b: 'Fun',
  c: {
    c2: [3, 2, 1, 0],
    c3: null
  }
}

Another Note: z-index must be considered when looking at children objects relative to other objects.

For example

<div class="container">
    <div class="branch_1">
        <div class="branch_1__child"></div>
    </div>
    <div class="branch_2">
        <div class="branch_2__child"></div>
    </div>
</div>

If you gave branch_1__child a z-index of 99 and you gave branch_2__child a z-index of 1, but you also gave your branch_2 a z-index of 10 and your branch_1 a z-index of 1, your branch_1__child still will not show up in front of your branch_2__child

Anyways, what I'm trying to say is; if a parent of an element you'd like to be placed in front has a lower z-index than its relative, that element will not be placed higher.

The z-index is relative to its containers. A z-index placed on a container farther up in the hierarchy basically starts a new "layer"

Mischief managed

There are many way you can do this. Based on your requirement choose anything from below.

1. By REVERTing commit:

If you want to REVERT all the changes from you last COMMIT that means If you ADD something in your file that will be REMOVED after revert has been done. If you REMOVE something in your file the revert process will ADD those file.

You can REVERT the very last COMMIT. Like:

1.git revert head^
2.git push origin <Branch-Name>

Or you can revert to any previous commit using the hash of that commit.Like:

1.git revert <SHA>
2.git push origin  <Branch-Name>

2. By RESETing previous Head

If you want to just point to any previous commit use reset; it points your local environment back to a previous commit. You can reset your head to previous commit or reset your head to previous any commit.

Reset to previous commit.

1.git reset head^
2.git push -f origin <Branch-name>

Reset to any previous commit:

1.git reset <SHA>
2.git push -f origin <Branch-name>

Trade of between REVERT & RESET:

Why would you choose to do a revert over a reset operation? If you have already pushed your chain of commits to the remote repository (where others may have pulled your code and started working with it), a revert is a nicer way to cancel out changes for them. This is because the Git workflow works well for picking up additional commits at the end of a branch, but it can be challenging if a set of commits is no longer seen in the chain when someone resets the branch pointer back.

I think you actually provided a good start for the correct answer right in your question (you just need the correct syntax). I had this exact same problem, and putting DISTINCT in a sub-query was indeed less costly than what other answers here have proposed.

select a.FirstName, a.LastName, v.District
from AddTbl a 
inner join (select distinct LastName, District 
    from ValTbl) v
   on a.LastName = v.LastName
order by Firstname   

Have you tried using Unix style slashes (/ instead of \)?

\ is often an escape or command character, and may be the source of confusion. I have never had issues with this, but I also do not have Windows, so I cannot test it.

Additionally, the permissions may be based on the user running psql, or maybe the user executing the postmaster service, check that both have read to that file in that directory.

You should declare the thread main as:

void* print_message(void*) // takes one parameter, unnamed if you aren't using it

For single color foreground color

label.setForeground(Color.RED)

For multiple foreground colors in the same label:

(I would probably put two labels next to each other using a GridLayout or something, but here goes...)

You could use html in your label text as follows:

frame.add(new JLabel("<html>Text color: <font color='red'>red</font></html>"));

which produces:

You might try using a library like redux-saga. It allows for a very clean way to sequence async functions, fire off actions, use delays and more. It is very powerful!

NO, But we have alternative in the form of function overloading.

called when no parameter passed

void operation(){

int a = 0;
int b = 0;

} 

called when "a" parameter was passed

void operation(int a){

int b = 0;
//code

} 

called when parameter b passed

void operation(int a , int b){
//code
} 

This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:

The Python Tutorial » Classes » Private Variables

For Mac use this command

  ./gradlew task-name

Here's a function that does what you want:

import re

def is_match(regex, text):
    pattern = re.compile(regex, text)
    return pattern.search(text) is not None

The regular expression search method returns an object on success and None if the pattern is not found in the string. With that in mind, we return True as long as the search gives us something back.

Examples:

>>> is_match('ba[rzd]', 'foobar')
True
>>> is_match('ba[zrd]', 'foobaz')
True
>>> is_match('ba[zrd]', 'foobad')
True
>>> is_match('ba[zrd]', 'foobam')
False

Perhaps not as Pyhtonic a solution, but easier to read for noobs like me:

charlist = [34, 38, 49, 67, 89, 45, 103, 105, 119, 125]
mystring = ""
for char in charlist:
    mystring = mystring + chr(char)
print mystring

os.walk is the answer, this will find the first match:

import os

def find(name, path):
    for root, dirs, files in os.walk(path):
        if name in files:
            return os.path.join(root, name)

And this will find all matches:

def find_all(name, path):
    result = []
    for root, dirs, files in os.walk(path):
        if name in files:
            result.append(os.path.join(root, name))
    return result

And this will match a pattern:

import os, fnmatch
def find(pattern, path):
    result = []
    for root, dirs, files in os.walk(path):
        for name in files:
            if fnmatch.fnmatch(name, pattern):
                result.append(os.path.join(root, name))
    return result

find('*.txt', '/path/to/dir')

After all this, I found a new easier method try this ..

It can join multiple photos together:

public static System.Drawing.Bitmap CombineBitmap(string[] files)
{
    //read all images into memory
    List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>();
    System.Drawing.Bitmap finalImage = null;

    try
    {
        int width = 0;
        int height = 0;

        foreach (string image in files)
        {
            //create a Bitmap from the file and add it to the list
            System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image);

            //update the size of the final bitmap
            width += bitmap.Width;
            height = bitmap.Height > height ? bitmap.Height : height;

            images.Add(bitmap);
        }

        //create a bitmap to hold the combined image
        finalImage = new System.Drawing.Bitmap(width, height);

        //get a graphics object from the image so we can draw on it
        using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage))
        {
            //set background color
            g.Clear(System.Drawing.Color.Black);

            //go through each image and draw it on the final image
            int offset = 0;
            foreach (System.Drawing.Bitmap image in images)
            {
                g.DrawImage(image,
                  new System.Drawing.Rectangle(offset, 0, image.Width, image.Height));
                offset += image.Width;
            }
        }

        return finalImage;
    }
    catch (Exception ex)
    {
        if (finalImage != null)
            finalImage.Dispose();

        throw ex;
    }
    finally
    {
        //clean up memory
        foreach (System.Drawing.Bitmap image in images)
        {
            image.Dispose();
        }
    }
}

Using @Arun dummy data :) here a lattice solution :

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

Put the backslash at the end of the line:

alert("Please Select file\
 to delete");

Edit    I have to note that this is not part of ECMAScript strings as line terminating characters are not allowed at all:

A 'LineTerminator' character cannot appear in a string literal, even if preceded by a backslash \. The correct way to cause a line terminator character to be part of the string value of a string literal is to use an escape sequence such as \n or \u000A.

So using string concatenation is the better choice.

Update 2015-01-05    String literals in ECMAScript5 allow the mentioned syntax:

A line terminator character cannot appear in a string literal, except as part of a LineContinuation to produce the empty character sequence. The correct way to cause a line terminator character to be part of the String value of a string literal is to use an escape sequence such as \n or \u000A.

Add "-O file.tgz" or "-O file.tar.gz" at the end wget command and extract "file.tgz" or "file.tar.gz"

Instead of using an enum use a static class.

replace

private enum PublishStatuses{
    NotCompleted,
    Completed,
    Error
};

with

private static class PublishStatuses{
    public static readonly string NotCompleted = "Not Completed";
    public static readonly string Completed = "Completed";
    public static readonly string Error = "Error";
};

it will be used like this

PublishStatuses.NotCompleted; // "Not Completed"

Issue using the top "extension method" solutions:

A private enum is often used inside another class. The extension method solution is not valid there since it must be in it's own class. This solution can be private and embedded in another class.

An alternative to overcome this is running the change detector manually.

You first inject the ChangeDetectorRef:

constructor(private changeDetector : ChangeDetectorRef) {}

Then you call it after updating the variable that controls the *ngIf

show() {
        this.display = true;
        this.changeDetector.detectChanges();
    }

You can also do

rake db:rollback

if you have not added any data to the tables.Then edit the migration file by adding the email column to it and then call

rake db:migrate

This will work if you have rails 3.1 onwards installed in your system.

Much simpler way of doing it is change let the change in migration file be as it is. use

$rake db:migrate:redo

This will roll back the last migration and migrate it again.

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

Example: Read json from file

/* test.json */
{
   "appDesc": {
      "description": "SomeDescription",
      "message": "SomeMessage"
   },
   "appName": {
      "description": "Home",
      "message": "Welcome",
      "imp":["awesome","best","good"]
   }
}


void readJson()
   {
      QString val;
      QFile file;
      file.setFileName("test.json");
      file.open(QIODevice::ReadOnly | QIODevice::Text);
      val = file.readAll();
      file.close();
      qWarning() << val;
      QJsonDocument d = QJsonDocument::fromJson(val.toUtf8());
      QJsonObject sett2 = d.object();
      QJsonValue value = sett2.value(QString("appName"));
      qWarning() << value;
      QJsonObject item = value.toObject();
      qWarning() << tr("QJsonObject of description: ") << item;

      /* in case of string value get value and convert into string*/
      qWarning() << tr("QJsonObject[appName] of description: ") << item["description"];
      QJsonValue subobj = item["description"];
      qWarning() << subobj.toString();

      /* in case of array get array and convert into string*/
      qWarning() << tr("QJsonObject[appName] of value: ") << item["imp"];
      QJsonArray test = item["imp"].toArray();
      qWarning() << test[1].toString();
   }

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

Example: Read json from string

Assign json to string as below and use the readJson() function shown before:

val =   
'  {
       "appDesc": {
          "description": "SomeDescription",
          "message": "SomeMessage"
       },
       "appName": {
          "description": "Home",
          "message": "Welcome",
          "imp":["awesome","best","good"]
       }
    }';

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

You can use docker-compose run instead of docker-compose up and tack the arguments on the end. For example:

docker-compose run dperson/samba arg1 arg2 arg3

If you need to connect to other docker containers, use can use --service-ports option:

docker-compose run --service-ports dperson/samba arg1 arg2 arg3

You could try this:

SELECT * INTO tbl_NewTableName 
FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Then run a simple delete:

DELETE FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

You can use the following in the web module that produces the war:

<build>
  <finalName>bird</finalName>
 . . .
</build>

This leads to a file called bird.war to be created when goal "war:war" is used.

I had the same issue but I executed mvn install initially (not install:install as it was mentioned earlier).

The solution is to include:

 <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-install-plugin</artifactId>
        <version>2.5.2</version>
 </plugin>

Into plugin management section.

the css odd and even is not support for IE. recommend you using solution below.

Best solution:

li:nth-child(2n+1) { color:green; } // for odd
li:nth-child(2n+2) { color:red; } // for even

li:nth-child(1n) { color:green; }
li:nth-child(2n) { color:red; }

<ul>
  <li>list element 1</li>
  <li>list element 2</li>
  <li>list element 3</li>
  <li>list element 4</li>
</ul>

You need commas after end finishing the case statement. And, the "as" goes after the case statement, not inside it:

Insert into TblStuff(FullName, Address, City, Zip)
    Select (Case When Middle is Null Then Fname + LName
                 Else Fname +' ' + Middle + ' '+ Lname
            End)  as FullName,
           (Case When Address2 is Null Then Address1
                 else Address1 +', ' + Address2
            End)  as  Address,
           City as City,
           Zip as Zip
    from tblImport

You can also used below code

<html>
<head>
    <style>
        .labelClass{
            float: left;
            width: 113px;
        }
    </style>
</head>
<body>
  <form action="yourclassName.jsp">
    <span class="labelClass">First name: </span><input type="text" name="fname"><br>
    <span class="labelClass">Last name: </span><input type="text" name="lname"><br>
    <input type="submit" value="Submit">
  </form>
</body>
