I think this String.Equals is what you need.

Dim aaa = "12/31"
            Dim a = String.Equals(aaa, "06/30")

a will return false.

If you are converting html to pdf on the html server side you can use Rotativa :

Install-Package Rotativa

This is based on wkhtmltopdf but it has better css support than iTextSharp has and is very simple to integrate with MVC (which is mostly used) as you can simply return the view as pdf:

public ActionResult GetPdf()
{
    //...
    return new ViewAsPdf(model);// and you are done!
} 

I solved this problem by adding a serialization method to my model:

def toJSON(self):
    import simplejson
    return simplejson.dumps(dict([(attr, getattr(self, attr)) for attr in [f.name for f in self._meta.fields]]))

Here's the verbose equivalent for those averse to one-liners:

def toJSON(self):
    fields = []
    for field in self._meta.fields:
        fields.append(field.name)

    d = {}
    for attr in fields:
        d[attr] = getattr(self, attr)

    import simplejson
    return simplejson.dumps(d)

_meta.fields is an ordered list of model fields which can be accessed from instances and from the model itself.

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

I have written my method for this, have fun testing it on your browsers, and give me feedback.

cheers.

function TextareaControl(textarea,charlimit,charCounter){
    if(
            textarea.tagName.toLowerCase() === "textarea" && 
            typeof(charlimit)==="number" &&
            typeof(charCounter) === "object" && 
            charCounter.innerHTML !== null
    ){
        var oldValue = textarea.value;
        textarea.addEventListener("keyup",function(){
            var charsLeft = charlimit-parseInt(textarea.value.length,10);
            if(charsLeft<0){
                textarea.value = oldValue;
                charsLeft = charlimit-parseInt(textarea.value.length,10);
            }else{
                oldValue = textarea.value;
            }
            charCounter.innerHTML = charsLeft;
        },false);
    }
}

Simply call test2 from test1 like:

EXEC test2 @newId, @prod, @desc;

Make sure to get @id using SCOPE_IDENTITY(), which gets the last identity value inserted into an identity column in the same scope:

SELECT @newId = SCOPE_IDENTITY()

Include in the GROUP BY clause all SELECT expressions that are not group function arguments.

you can do like this. imageuri can be converted into string like this.

intent.putExtra("imageUri", imageUri.toString());

I followed each of the suggestions here (I'm using Angular 7), but nothing worked. My app refused to acknowledge that @angular/material existed, so it showed an error on this line:

import { MatCheckboxModule } from '@angular/material';

Even though I was using the --save parameter to add Angular Material to my project:

npm install --save @angular/material @angular/cdk

...it refused to add anything to my "package.json" file.

I even tried deleting the package-lock.json file, as some articles suggest that this causes problems, but this had no effect.

To fix this issue, I had to manually add these two lines to my "package.json" file.

{
    "devDependencies": {
        ...
        "@angular/material": "~7.2.2",
        "@angular/cdk": "~7.2.2",
        ...

What I can't tell is whether this is an issue related to using Angular 7, or if it's been around for years....

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

There seems to be a bug in Visual Studio 2015 community. For a 64-bit project, the include folder isn't found unless it's in the win32 bit configuration Additional Include Folders list.

Try to add export PATH=$PATH:/home/me/play in ~/.bashrc file.

Your append line must be in your test() function

EDIT:

Here are two versions:

Version 1: jQuery listener

$(function(){
    $('button').on('click',function(){
        var r= $('<input type="button" value="new button"/>');
        $("body").append(r);
    });
});

DEMO HERE

Version 2: With a function (like your example)

function createInput(){
    var $input = $('<input type="button" value="new button" />');
    $input.appendTo($("body"));
}

DEMO HERE

Note: This one can be done with either .appendTo or with .append.

Just re-posting answer by oleynikd because it's simple and neat

Bundle bundle = ActivityOptionsCompat.makeCustomAnimation(getContext(),
    android.R.anim.fade_in, android.R.anim.fade_out).toBundle(); 
startActivity(intent, bundle);

You can set your content-type header so clients know to expect json

w.Header().Set("Content-Type", "application/json")

Another way to marshal a struct to json is to build an encoder using the http.ResponseWriter

// get a payload p := Payload{d}
json.NewEncoder(w).Encode(p)

After reading Misko's articles I believe that static methods are bad from a testing point of view. You should have factories instead(maybe using a dependency injection tool like Guice).

how do I ensure that I only have one of something

only have one of something The problem of “how do I ensure that I only have one of something” is nicely sidestepped. You instantiate only a single ApplicationFactory in your main, and as a result, you only instantiate a single instance of all of your singletons.

The basic issue with static methods is they are procedural code

The basic issue with static methods is they are procedural code. I have no idea how to unit-test procedural code. Unit-testing assumes that I can instantiate a piece of my application in isolation. During the instantiation I wire the dependencies with mocks/friendlies which replace the real dependencies. With procedural programing there is nothing to "wire" since there are no objects, the code and data are separate.

>>> [1,2,3,4,5,6,7,8,9][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]

Simple object hasher:

(function () {
    Number.prototype.toHex = function () {
        var ret = ((this<0?0x8:0)+((this >> 28) & 0x7)).toString(16) + (this & 0xfffffff).toString(16);
        while (ret.length < 8) ret = '0'+ret;
        return ret;
    };
    Object.hashCode = function hashCode(o, l) {
        l = l || 2;
        var i, c, r = [];
        for (i=0; i<l; i++)
            r.push(i*268803292);
        function stringify(o) {
            var i,r;
            if (o === null) return 'n';
            if (o === true) return 't';
            if (o === false) return 'f';
            if (o instanceof Date) return 'd:'+(0+o);
            i=typeof o;
            if (i === 'string') return 's:'+o.replace(/([\\\\;])/g,'\\$1');
            if (i === 'number') return 'n:'+o;
            if (o instanceof Function) return 'm:'+o.toString().replace(/([\\\\;])/g,'\\$1');
            if (o instanceof Array) {
                r=[];
                for (i=0; i<o.length; i++) 
                    r.push(stringify(o[i]));
                return 'a:'+r.join(';');
            }
            r=[];
            for (i in o) {
                r.push(i+':'+stringify(o[i]))
            }
            return 'o:'+r.join(';');
        }
        o = stringify(o);
        for (i=0; i<o.length; i++) {
            for (c=0; c<r.length; c++) {
                r[c] = (r[c] << 13)-(r[c] >> 19);
                r[c] += o.charCodeAt(i) << (r[c] % 24);
                r[c] = r[c] & r[c];
            }
        }
        for (i=0; i<r.length; i++) {
            r[i] = r[i].toHex();
        }
        return r.join('');
    }
}());

The meat here is the stringifier, which simply converts any object into a unique string. hashCode then runs over the object, hashing together the characters of the stringified object.

For extra points, export the stringifier and create a parser.

The databases are stored as SQLite files in /data/data/PACKAGE/databases/DATABASEFILE where:

• PACKAGE is the package declared in the AndroidManifest.xml (tag "manifest", attribute "package")
• DATABASEFILE is the name passed when you call the SQLiteOpenHelper constructor as explained here: http://developer.android.com/guide/topics/data/data-storage.html#db

You can see (copy from/to filesystem) the database file in the emulator selecting DDMS perspective, in the File Explorer tab.

The best way to send data from a parent component to a child is using props.

Passing data from parent to child via props

• Declare props (array or object) in the child
• Pass it to the child via <child :name="variableOnParent">

See demo below:

Vue.component('child-comp', {
  props: ['message'], // declare the props
  template: '<p>At child-comp, using props in the template: {{ message }}</p>',
  mounted: function () {
    console.log('The props are also available in JS:', this.message);
  }
})

new Vue({
  el: '#app',
  data: {
    variableAtParent: 'DATA FROM PARENT!'
  }
})

<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>

<div id="app">
  <p>At Parent: {{ variableAtParent }}<br>And is reactive (edit it) <input v-model="variableAtParent"></p>
  <child-comp :message="variableAtParent"></child-comp>
</div>

I am creating a java method for this purpose with dynamic character

public String insertSpace(String myString,int indexno,char myChar){
    myString=myString.substring(0, indexno)+ myChar+myString.substring(indexno);
    System.out.println(myString);
    return myString;
}

Not quite

int main(void)
{
   #if 0
     the apostrophe ' causes a warning
   #endif
   return 0;
}

It shows "t.c:4:19: warning: missing terminating ' character" with gcc 4.2.4

You can also do

console.log("a = %o, b = %o", a, b);

where a and b are objects.

ok, this is a extract from the make function in hash.php

    $work = str_pad(8, 2, '0', STR_PAD_LEFT);

    // Bcrypt expects the salt to be 22 base64 encoded characters including
    // dots and slashes. We will get rid of the plus signs included in the
    // base64 data and replace them with dots.
    if (function_exists('openssl_random_pseudo_bytes'))
    {
        $salt = openssl_random_pseudo_bytes(16);
    }
    else
    {
        $salt = Str::random(40);
    }

    $salt = substr(strtr(base64_encode($salt), '+', '.'), 0 , 22);

    echo crypt('yourpassword', '$2a$'.$work.'$'.$salt);

Just copy/paste it into a php file and run it.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

neither try any above ways nor sudo apt autoremove python3 because it will remove all gnome based applications from your system including gnome-terminal. In case if you have done that mistake and left with kernal only than trysudo apt install gnome on kernal.

try to change your default python version instead removing it. you can do this through bashrc file or export path command.

The particular exception message is telling you that the mentioned class is missing in the classpath. As the org.apache.commons.io package name hints, the mentioned class is part of the http://commons.apache.org/io project.

And indeed, Commons FileUpload has Commons IO as a dependency. You need to download and drop commons-io.jar in the /WEB-INF/lib as well.

Doing this fixed my issue

<script type="text/javascript">
    function SubmitFrm(){
        var Searchtxt = document.getElementById("txtSearch").value;
        window.location = "http://www.mysite.com/search/?Query=" + Searchtxt;
    }
</script>

I changed .value(); to .value; taking out the ()

I did not change anything in my text field or submit button

<input name="txtSearch" type="text" id="txtSearch" class="field" />            
<input type="submit" name="btnSearch" value="" id="btnSearch" class="btn" onclick="javascript:SubmitFrm()" />

Works like a charm.

You can use two elements, one inside the other, and give the outer one overflow: hidden and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"

#outer {
    width: 100px;
    overflow: hidden;
    padding-bottom: 10px;
}

#outer > div {
    width: 100px;
    height: 100px;
    background: orange;

    -moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}

Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/

This might work for you:

cat <<\! >names.txt
> alison
> barb
> charlie
> david
> !
OIFS=$IFS; IFS=$'\n'; NAMES=($(<names.txt)); IFS=$OIFS
echo "${NAMES[@]}"
alison barb charlie david
echo "${NAMES[0]}"
alison
for NAME in "${NAMES[@]}";do echo $NAME;done
alison
barb
charlie
david

As has already been pointed out by others, using a function should be considered best practice.

However, here is another approach, leveraging xargs:

alias junk="xargs -I "{}" -- mv "{}" "~/.Trash" <<< "

Note that this has side effects regarding redirection of streams.

In my case it happens when i want add view by parent to other view

View root = inflater.inflate(R.layout.single, null);
LinearLayout lyt = root.findViewById(R.id.lytRoot);
lytAll.addView(lyt);  // ->  crash

you must add parent view like this

View root = inflater.inflate(R.layout.single, null);
LinearLayout lyt = root.findViewById(R.id.lytRoot);
lytAll.addView(root);

I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a), because I was wondering how to accomplish this using exec. I came across a creative solution using here-doc syntax and .: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script

I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:

#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor 
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged

It is not as readable as the exec solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh implements multios, but it may have less overhead than tee. Unfortunately it seems that one cannot use multios with exec.

It's all about trying all those answers, for me, nothing works except the next solution: Google font suggested

@import 'https://fonts.googleapis.com/css?family=Assistant';

But, I'm using here foreign language fonts, and it didn't work on IE11 only. I found out this solution that worked:

@import 'https://fonts.googleapis.com/css?family=Assistant&subset=hebrew';

Hope that save someone precious time

In my case, with letsencrypt https, this was caused by using cert.pem instead of fullchain.pem as the certificate file on the requested server. See this thread for details.

How about

<input type="text" pattern="[789][0-9]{9}">

List<Object> list = new ArrayList();
for (Iterator<Object> iterator = list.iterator(); iterator.hasNext();) {
  Object obj= iterator.next();
    if (obj.getId().equals("1")) {
       // Remove the current element from the iterator and the list.
       iterator.remove();
    }
}

Thanks @Harry the following code works for me:

.your-div{
   vertical-align: bottom;
   display: table-cell;
}

Or you could use the "correct" method, similar to your original atoi approach, but with std::stringstream instead. That should work with chars as input as well as strings. (boost::lexical_cast is another option for a more convenient syntax)

(atoi is an old C function, and it's generally recommended to use the more flexible and typesafe C++ equivalents where possible. std::stringstream covers conversion to and from strings)

You can use the fuser command, like:

fuser file_name

You will receive a list of processes using the file.

You can use different flags with it, in order to receive a more detailed output.

You can find more info in the fuser's Wikipedia article, or in the man pages.

Another solution to this is border-spacing property:

table td {_x000D_
  border-bottom: 2px solid black;_x000D_
}_x000D_
_x000D_
table {_x000D_
  border-spacing: 0px;_x000D_
}

<table>_x000D_
 <tr>_x000D_
   <td>ABC</td>_x000D_
   <td>XYZ</td>_x000D_
</table>

1. To closed ideas,
2. To remove all folder and file C:/Users/UserName/.m2/org/*,
3. Open ideas and update Maven project,(right click on project -> maven->update maven project)
4. After that update the project.

Tbl.ListRows.Add doesn't work for me and I believe lot others are facing the same problem. I use the following workaround:

    'First check if the last row is empty; if not, add a row
    If table.ListRows.count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.count).Range
        For col = 1 To lastRow.Columns.count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                lastRow.Cells(1, col).EntireRow.Insert
                'Cut last row and paste to second last
                lastRow.Cut Destination:=table.ListRows(table.ListRows.count - 1).Range
                Exit For
            End If
        Next col
    End If

    'Populate last row with the form data
    Set lastRow = table.ListRows(table.ListRows.count).Range
    Range("E7:E10").Copy
    lastRow.PasteSpecial Transpose:=True
    Range("E7").Select
    Application.CutCopyMode = False

Hope it helps someone out there.

None of the above answers show you how to extract a variable from a non-running container (if you use the echo approach with run, you won't get any output).

Simply run with printenv, like so:

docker run --rm <container> printenv <MY_VAR>

(Note that docker-compose instead of docker works too)

    $url ="https://yourFile.pdf";
    $content = file_get_contents($url);

    header('Content-Type: application/pdf');
    header('Content-Length: ' . strlen($content));
    header('Content-Disposition: inline; filename="YourFileName.pdf"');
    header('Cache-Control: private, max-age=0, must-revalidate');
    header('Pragma: public');
    ini_set('zlib.output_compression','0');

    die($content);

Tested and works fine. If you want the file to download instead, replace

    Content-Disposition: inline

with

    Content-Disposition: attachment

I had a similar error recently with the log4net error:

Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692fbea5521e1304'

Making sure the build was targeting only x86 worked for me.

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

It can also be done with isinstance as per Alex Hall's answer :

>>> NoneType = type(None)
>>> x = None
>>> type(x) == NoneType
True
>>> isinstance(x, NoneType)
True

isinstance is also intuitive but there is the complication that it requires the line

NoneType = type(None)

which isn't needed for types like int and float.

The final keyword indicates that a variable may only be initialized once. In your code you are only performing one initialization of final so the terms are satisfied. This statement performs the lone initialization of foo. Note that final != immutable, it only means that the reference cannot change.

foo = new ArrayList();

When you declare foo as static final the variable must be initialized when the class is loaded and cannot rely on instantiation (aka call to constructor) to initialize foo since static fields must be available without an instance of a class. There is no guarantee that the constructor will have been called prior to using the static field.

When you execute your method under the static final scenario the Test class is loaded prior to instantiating t at this time there is no instantiation of foo meaning it has not been initialized so foo is set to the default for all objects which is null. At this point I assume your code throws a NullPointerException when you attempt to add an item to the list.

In my case, it is taking time in AM and PM but sending data in 00-24 hours format to the server on form submit. and when use that DB data in its value then it will automatically select the appropriate AM or PM to edit form value.

You can write a serialize class to do that:

public class Symbol

{
     private String symbol;

     private String name;

     public String getSymbol() {
        return symbol;
    }
    public void setSymbol(String symbol) {
        this.symbol = symbol;
    }    
    public String getName() {
        return name;
    }    
    public void setName(String name) {
        this.name = name;
    }
}

public class SymbolJsonSerializer extends JsonSerializer<Symbol> {

    @Override
    public void serialize(Symbol symbol, JsonGenerator jgen, SerializerProvider serializers) throws IOException, JsonProcessingException {
        jgen.writeStartObject();

        jgen.writeStringField("symbol", symbol.getSymbol());
         //Changed name to full_name as the field name of Json string
        jgen.writeStringField("full_name", symbol.getName());
        jgen.writeEndObject(); 
    }
}

            ObjectMapper mapper = new ObjectMapper();

            SimpleModule module = new SimpleModule();
            module.addSerializer(Symbol.class, new SymbolJsonSerializer());
            mapper.registerModule(module); 

            //only convert non-null field, option...
            mapper.setSerializationInclusion(Include.NON_NULL); 

            String jsonString = mapper.writeValueAsString(symbolList);

For your validation event IMO the easiest method would be to use a character array to validate textbox characters against. True - iterating and validating isn't particularly efficient, but it is straightforward.

Alternately, use a regular expression of your whitelist characters against the input string. Your events are availalbe at MSDN here: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.lostfocus.aspx

Doesn't look like you are using the correct overload of ActionLink. Try this:-

<%=Html.ActionLink("Modify Villa", "Modify", new {id = "1"})%>

This assumes your view is under the /Views/Villa folder. If not then I suspect you need:-

<%=Html.ActionLink("Modify Villa", "Modify", "Villa", new {id = "1"}, null)%>

The event is probably raised before the elements are fully loaded or the references are still unset, hence the exceptions. Try only setting properties if the reference is not null and IsLoaded is true.

In my case I had to redownload it, something was wrong with the one I downloaded. Its size was far much less than the one on the website.

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

Try this

public ActionResult CreatePerson(string Enc)

 window.location = '@Url.Action("CreatePerson", "Person", new { Enc = "id", actionType = "Disable" })'.replace("id", id).replace("&", "&");

you will get the id inside the Enc string.

FWIW, here are a couple of non-RE alternatives that I think are neater than poke's solution.

The first uses str.index and checks for ValueError:

def findall(sub, string):
    """
    >>> text = "Allowed Hello Hollow"
    >>> tuple(findall('ll', text))
    (1, 10, 16)
    """
    index = 0 - len(sub)
    try:
        while True:
            index = string.index(sub, index + len(sub))
            yield index
    except ValueError:
        pass

The second tests uses str.find and checks for the sentinel of -1 by using iter:

def findall_iter(sub, string):
    """
    >>> text = "Allowed Hello Hollow"
    >>> tuple(findall_iter('ll', text))
    (1, 10, 16)
    """
    def next_index(length):
        index = 0 - length
        while True:
            index = string.find(sub, index + length)
            yield index
    return iter(next_index(len(sub)).next, -1)

To apply any of these functions to a list, tuple or other iterable of strings, you can use a higher-level function —one that takes a function as one of its arguments— like this one:

def findall_each(findall, sub, strings):
    """
    >>> texts = ("fail", "dolly the llama", "Hello", "Hollow", "not ok")
    >>> list(findall_each(findall, 'll', texts))
    [(), (2, 10), (2,), (2,), ()]
    >>> texts = ("parallellized", "illegally", "dillydallying", "hillbillies")
    >>> list(findall_each(findall_iter, 'll', texts))
    [(4, 7), (1, 6), (2, 7), (2, 6)]
    """
    return (tuple(findall(sub, string)) for string in strings)

If you want all the ancestors rather than just the immediate ones, use inspect.getmro:

import inspect
print inspect.getmro(cls)

Usefully, this gives you all ancestor classes in the "method resolution order" -- i.e. the order in which the ancestors will be checked when resolving a method (or, actually, any other attribute -- methods and other attributes live in the same namespace in Python, after all;-).

Just extending other answers...

Delegated events handlers will not be removed upon element removal.

$('body').on('click', '#someEl', function (event){
  console.log(event);
});

$('#someEL').remove(); // removing the element from DOM

Now check:

$._data(document.body, 'events');

@bryc - yes, you could do it like this:

Element.prototype.setAttribute.apply(document.body,["foo","bar"])

But that seems like a lot of work and obfuscation compared to:

document.body.setAttribute("foo","bar")

For future reference, I ran into a similar problem; I was creating too many file descriptors (FDs) by creating too many files and sockets (on Unix OSs, everything is a FD). My solution was to increase FDs at runtime with setrlimit().

First I got the FD limits, with the following code:

// This goes somewhere in your code
struct rlimit rlim;

if (getrlimit(RLIMIT_NOFILE, &rlim) == 0) {
    std::cout << "Soft limit: " << rlim.rlim_cur << std::endl;
    std::cout << "Hard limit: " << rlim.rlim_max << std::endl;
} else {
    std::cout << "Unable to get file descriptor limits" << std::endl;
}

After running getrlimit(), I could confirm that on my system, the soft limit is 256 FDs, and the hard limit is infinite FDs (this is different depending on your distro and specs). Since I was creating > 300 FDs between files and sockets, my code was crashing.

In my case I couldn't decrease the number of FDs, so I decided to increase the FD soft limit instead, with this code:

// This goes somewhere in your code
struct rlimit rlim;

rlim.rlim_cur = NEW_SOFT_LIMIT;
rlim.rlim_max = NEW_HARD_LIMIT;

if (setrlimit(RLIMIT_NOFILE, &rlim) == -1) {
    std::cout << "Unable to set file descriptor limits" << std::endl;
}

Note that you can also get the number of FDs that you are using, and the source of these FDs, with this code.

Also you can find more information on gettrlimit() and setrlimit() here and here.

If you have a base or header template that's included everywhere why not include the favicon there with basic HTML?

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

This data not found causes because of some datatype we are using .

like select empid into v_test

above empid and v_test has to be number type , then only the data will be stored .

So keep track of the data type , when getting this error , may be this will help

You should create all your virtualenvs in one folder, such as virt.

Assuming your virtualenv folder name is virt, if not change it

cd
mkdir custom

Copy the below lines...

#!/usr/bin/env bash
ENV_PATH="$HOME/virt/$1/bin/activate"
bash --rcfile $ENV_PATH -i

Create a shell script file and paste the above lines...

touch custom/vhelper
nano custom/vhelper

Grant executable permission to your file:

sudo chmod +x custom/vhelper

Now export that custom folder path so that you can find it on the command-line by clicking tab...

export PATH=$PATH:"$HOME/custom"

Now you can use it from anywhere by just typing the below command...

vhelper YOUR_VIRTUAL_ENV_FOLDER_NAME

Suppose it is abc then...

vhelper abc

pg_get_serial_sequence can be used to avoid any incorrect assumptions about the sequence name. This resets the sequence in one shot:

SELECT pg_catalog.setval(pg_get_serial_sequence('table_name', 'id'), (SELECT MAX(id) FROM table_name)+1);

Or more concisely:

SELECT pg_catalog.setval(pg_get_serial_sequence('table_name', 'id'), MAX(id)) FROM table_name;

However this form can't handle empty tables correctly, since max(id) is null, and neither can you setval 0 because it would be out of range of the sequence. One workaround for this is to resort to the ALTER SEQUENCE syntax i.e.

ALTER SEQUENCE table_name_id_seq RESTART WITH 1;
ALTER SEQUENCE table_name_id_seq RESTART; -- 8.4 or higher

But ALTER SEQUENCE is of limited use because the sequence name and restart value cannot be expressions.

It seems the best all-purpose solution is to call setval with false as the 3rd parameter, allowing us to specify the "next value to use":

SELECT setval(pg_get_serial_sequence('t1', 'id'), coalesce(max(id),0) + 1, false) FROM t1;

This ticks all my boxes:

1. avoids hard-coding the actual sequence name
2. handles empty tables correctly
3. handles tables with existing data, and does not leave a hole in the sequence

Finally, note that pg_get_serial_sequence only works if the sequence is owned by the column. This will be the case if the incrementing column was defined as a serial type, however if the sequence was added manually it is necessary to ensure ALTER SEQUENCE .. OWNED BY is also performed.

i.e. if serial type was used for table creation, this should all work:

CREATE TABLE t1 (
  id serial,
  name varchar(20)
);

SELECT pg_get_serial_sequence('t1', 'id'); -- returns 't1_id_seq'

-- reset the sequence, regardless whether table has rows or not:
SELECT setval(pg_get_serial_sequence('t1', 'id'), coalesce(max(id),0) + 1, false) FROM t1;

But if sequences were added manually:

CREATE TABLE t2 (
  id integer NOT NULL,
  name varchar(20)
);

CREATE SEQUENCE t2_custom_id_seq
    START WITH 1
    INCREMENT BY 1
    NO MINVALUE
    NO MAXVALUE
    CACHE 1;

ALTER TABLE t2 ALTER COLUMN id SET DEFAULT nextval('t2_custom_id_seq'::regclass);

ALTER SEQUENCE t2_custom_id_seq OWNED BY t2.id; -- required for pg_get_serial_sequence

SELECT pg_get_serial_sequence('t2', 'id'); -- returns 't2_custom_id_seq'

-- reset the sequence, regardless whether table has rows or not:
SELECT setval(pg_get_serial_sequence('t2', 'id'), coalesce(max(id),0) + 1, false) FROM t1;

Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.

So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.

There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.

Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example

class MyInput
{
    String str1;
    String str2;

    public MyInput() { }
      //  getters, setters
 }

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}

Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.

The last option is to construct a POST body that looks like:

str1=value1&str2=value2

then add some additional annotations to your server method:

public void create(@QueryParam("str1") String str1, 
                  @QueryParam("str2") String str2)

@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).

If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

You can use Xtreme Download Manager(XDM) software for this. This software can download from any site in this format. Even this software can change the ts file format. You only need to change the format when downloading.

Update

As of jQuery 3.0, the new syntax is just .on:

see this answer here and the code:

$('iframe').on('load', function() {
    // do stuff 
});

Try this. Edit your build.gradle file as followed.

ext { profile = project.hasProperty('profile') ? project['profile'] : 'local' }

I ended up doing the following and it works:

return DatabaseContext.Applications
     .Include("Children.ChildRelationshipType");

I have converted to using Powershell calls for this purpose in my scripts. It requires script execution permission and is by far the slowest option. However it is also localization independent, very easy to write and read, and it is much more feasible to perform adjustments to the date like addition/subtraction or get the last day of the month, etc.

Here is how to get the day, month, and year

for /f %%i in ('"powershell (Get-Date).ToString(\"dd\")"') do set day=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"MM\")"') do set month=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"yyyy\")"') do set year=%%i

Or, here is yesterday's date in yyyy-MM-dd format

for /f %%i in ('"powershell (Get-Date).AddDays(-1).ToString(\"yyyy-MM-dd\")"') do set yesterday=%%i

Day of the week

for /f %%d in ('"powershell (Get-Date).DayOfWeek"') do set DayOfWeek=%%d

Current time plus 15 minutes

for /f %%i in ('"powershell (Get-Date).AddMinutes(15).ToString(\"HH:mm\")"') do set time=%%i

I got the following for me:

formSubmit('#login-form', '/api/user/login', '/members/');

where

function formSubmit(form, url, target) {
    $(form).submit(function(event) {
        $.post(url, $(form).serialize())
            .done(function(res) {
                if (res.success) {
                    window.location = target;
                }
                else {
                    alert(res.error);
                }
            })
            .fail(function(res) {
                alert("Server Error: " + res.status + " " + res.statusText);

            })
        event.preventDefault();
    });
}

This assumes the post to 'url' returns an ajax in the form of {success: false, error:'my Error to display'}

You can vary this as you like. Feel free to use that snippet.

As documented in /usr/src/linux/Documentation/block/switching-sched.txt, the I/O scheduler on any particular block device can be changed at runtime. There may be some latency as the previous scheduler's requests are all flushed before bringing the new scheduler into use, but it can be changed without problems even while the device is under heavy use.

# cat /sys/block/hda/queue/scheduler
noop deadline [cfq]
# echo anticipatory > /sys/block/hda/queue/scheduler
# cat /sys/block/hda/queue/scheduler
noop [deadline] cfq

Ideally, there would be a single scheduler to satisfy all needs. It doesn't seem to exist yet. The kernel often doesn't have enough knowledge to choose the best scheduler for your workload:

• noop is often the best choice for memory-backed block devices (e.g. ramdisks) and other non-rotational media (flash) where trying to reschedule I/O is a waste of resources
• deadline is a lightweight scheduler which tries to put a hard limit on latency
• cfq tries to maintain system-wide fairness of I/O bandwidth

The default was anticipatory for a long time, and it received a lot of tuning, but was removed in 2.6.33 (early 2010). cfq became the default some while ago, as its performance is reasonable and fairness is a good goal for multi-user systems (and even single-user desktops). For some scenarios -- databases are often used as examples, as they tend to already have their own peculiar scheduling and access patterns, and are often the most important service (so who cares about fairness?) -- anticipatory has a long history of being tunable for best performance on these workloads, and deadline very quickly passes all requests through to the underlying device.

If you're finding by Contains then it'll be like this

    $("input[id*='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Starts With then it'll be like this

    $("input[id^='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Ends With then it'll be like this

     $("input[id$='DiscountType']").each(function (i, el) {

If you want to select elements which id is not a given string

    $("input[id!='DiscountType']").each(function (i, el) {

I am running on FreeBSD 11.1, the freebsd jail virtualization concept makes the operating system optimal. The current version of Git I am using is 2.15.1, I also prefer to run everything on shell scripts. With that in mind I modified the suggestions above as followed:

git push: .git/hooks/pre-commit

#! /bin/sh -
#
# A hook script called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if it wants
# to stop the commit.

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

# Clear the permissions database file
> $DATABASE;

printf "Backing-up file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
for FILE in $(git ls-files);
do
   # Save the permissions of all the files in the index
    printf "%s;%s\n" $FILE $(stat -f "%Lp;%u;%g" $FILE) >> $DATABASE;
done
IFS=$OLDIFS;

# Add the permissions database file to the index
git add $DATABASE;

printf "OK\n";

git pull: .git/hooks/post-merge

#! /bin/sh -

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

printf "Restoring file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
while read -r LINE || [ -n "$LINE" ];
do
   FILE=$(printf "%s" $LINE | cut -d ";" -f 1);
   PERMISSIONS=$(printf "%s" $LINE | cut -d ";" -f 2);
   USER=$(printf "%s" $LINE | cut -d ";" -f 3);
   GROUP=$(printf "%s" $LINE | cut -d ";" -f 4);

   # Set the file permissions
   chmod $PERMISSIONS $FILE;

   # Set the file owner and groups
   chown $USER:$GROUP $FILE;

done < $DATABASE
IFS=$OLDIFS

pritnf "OK\n";

exit 0;

If for some reason you need to recreate the script the .permissions file output should have the following format:

.gitignore;644;0;0

For a .gitignore file with 644 permissions given to root:wheel

Notice I had to make a few changes to the stat options.

Enjoy,

use "xxx[]" as name of the field in formdata (you will get an array of - stringified objects - in you case)

so within your loop

$('.tag-form').each(function(i){
            article = $(this).find('input[name="article"]').val();
            gender = $(this).find('input[name="gender"]').val();
            brand = $(this).find('input[name="brand"]').val();
            this_tag = new Array();
            this_tag.article = article;
            this_tag.gender = gender;
            this_tag.brand = brand;
            //tags.push(this_tag);    
            formdata.append('tags[]', this_tag);
...

I've found that the following works if you're not using jQuery and only interested in cloning simple objects (see comments).

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

I like to do this

input[type="text"]
{
    background: rgba(0, 0, 0, 0);
    border: none;
    outline: none;
}

Setting the outline property to none stops the browser from highlighting the box when the cursor enters

What I found out was old but working solution on modern browsers. Works for not toggling classes on the double click.

$('*').click(function(event) {
    if(!event.detail || event.detail==1){//activate on first click only to avoid hiding again on double clicks
        // Toggle classes and do functions here
        $(this).slideToggle();
    }
});

If you want to enable CORS for all routes, then just install flask_cors extension (pip3 install -U flask_cors) and wrap app like this: CORS(app).

That is enough to do it (I tested this with a POST request to upload an image, and it worked for me):

from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app) # This will enable CORS for all routes

Important note: if there is an error in your route, let us say you try to print a variable that does not exist, you will get a CORS error related message which, in fact, has nothing to do with CORS.

The following command excludes the need for the find to filter out the svn folders by using a second grep.

grep -rL "foo" ./* | grep -v "\.svn"

If you meant "r" specifically:
It was migrated from homebrew/science to homebrew/core.

For r 3.4.3 Mac High Sierra:

brew tap homebrew/core
brew install Caskroom/cask/xquartz
brew install r

Below is an example:

value := r.FormValue("field")

for more info. about http package, you could visit its documentation here. FormValue basically returns POST or PUT values, or GET values, in that order, the first one that it finds.

It is not mentioned which environment is used for executing Liquibase. In case it is Spring Boot 2 it is possible to extend liquibase.lockservice.StandardLockService without the need to run direct SQL statements which is much cleaner. E.g.:

/**
 * This class is enforcing to release the lock from the database.
 *
 */
 public class ForceReleaseLockService extends StandardLockService {

    @Override
    public int getPriority() {
        return super.getPriority()+1;
    }

    @Override
    public void waitForLock() throws LockException {
        try {
            super.forceReleaseLock();
        } catch (DatabaseException e) {
            throw new LockException("Could not enforce getting the lock.", e);
        }
        super.waitForLock();
    }
}

The code is enforcing the release of the lock. This can be useful in test set-ups where the release call might not get called in case of errors or when the debugging is aborted.

The class must be placed in the liquibase.ext package and will be picked up by the Spring Boot 2 auto configuration.

One approach is to do that using the String class itself. Let's say that your string is something like that:

String s = "some text";
boolean hasNonAlpha = s.matches("^.*[^a-zA-Z0-9 ].*$");

one other is to use an external library, such as Apache commons:

String s = "some text";
boolean hasNonAlpha = !StringUtils.isAlphanumeric(s);

You got more preparing [for the exam] to do ;-)

The Stack Pointer is a register which holds the address of the next available spot on the stack.

The stack is a area in memory which is reserved to store a stack, that is a LIFO (Last In First Out) type of container, where we store the local variables and return address, allowing a simple management of the nesting of function calls in a typical program.

See this Wikipedia article for a basic explanation of the stack management.

Assuming your sm_id and c_id properties are public, you can access them by using a foreach on the array:

$array = array(/* objects in an array here */);
foreach ($array as $obj) {
    echo $obj->sm_id . '<br />' . $obj->c_id . '<br />';
}

If you want this sentence from foo.bar import foo2 to be loaded dynamically, you should do this

foo = __import__("foo")
bar = getattr(foo,"bar")
foo2 = getattr(bar,"foo2")

instance = foo2()

strstr(request, "favicon") != NULL

Only this worked for me (AndroidX support library):

 <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@null"
            android:theme="@style/AppTheme.AppBarOverlay"
            android:translationZ="0.1dp"
            app:elevation="0dp">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@null"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </com.google.android.material.appbar.AppBarLayout>

This code removes background in all necessary views and also removes shadow from AppBarLayout (which was a problem)

Answer was found here: remove shadow below AppBarLayout widget android

I would be very concerned about putting the load of sending e-mails on my database server (small though it may be). I might suggest one of these alternatives:

1. Have application logic detect the need to send an e-mail and send it.
2. Have a MySQL trigger populate a table that queues up the e-mails to be sent and have a process monitor that table and send the e-mails.

I have no idea about the year of publication of the question; it might be old now. So, I expect my answer to be more of a reference for future similar questions after my post.

I don't know if anybody out there has already given an answer similar to the one I am about to give, which might result -I think- being the simplest, most direct and most effective: If someone has already given it, I apologize, but I haven't seen it. Here, my answer using CStr instead of TEXT:

Asuming cell A1 contains a date, and using VBA code:

Dim strDate As String

'Convert to string the value contained in A1 (a date)
strDate = CStr([A1].Value)

You can, thereafter, manipulate it as any ordinary string using string functions (MID, LEFT, RIGHT, LEN, CONCATENATE (&), etc.)

Both join() and concat() way could solve the problem. However, there is one warning I have to mention: Reset the index before you join() or concat() if you trying to deal with some data frame by selecting some rows from another DataFrame.

One example below shows some interesting behavior of join and concat:

dat1 = pd.DataFrame({'dat1': range(4)})
dat2 = pd.DataFrame({'dat2': range(4,8)})
dat1.index = [1,3,5,7]
dat2.index = [2,4,6,8]

# way1 join 2 DataFrames
print(dat1.join(dat2))
# output
   dat1  dat2
1     0   NaN
3     1   NaN
5     2   NaN
7     3   NaN

# way2 concat 2 DataFrames
print(pd.concat([dat1,dat2],axis=1))
#output
   dat1  dat2
1   0.0   NaN
2   NaN   4.0
3   1.0   NaN
4   NaN   5.0
5   2.0   NaN
6   NaN   6.0
7   3.0   NaN
8   NaN   7.0

#reset index 
dat1 = dat1.reset_index(drop=True)
dat2 = dat2.reset_index(drop=True)
#both 2 ways to get the same result

print(dat1.join(dat2))
   dat1  dat2
0     0     4
1     1     5
2     2     6
3     3     7


print(pd.concat([dat1,dat2],axis=1))
   dat1  dat2
0     0     4
1     1     5
2     2     6
3     3     7

You can try with this code - based on Rows.Add method

DataTable table = new DataTable();
DataRow row = table.NewRow();
table.Rows.Add(row);

.then function of promiseB receives what is returned from .then function of promiseA.

here promiseA is returning is a number, which will be available as number parameter in success function of promiseB. which will then be incremented by 1

The .NET Framework System.IO provides the following functions for invalid file system characters:

• Path.GetInvalidFileNameChars
• Path.GetInvalidPathChars

Those functions should return appropriate results depending on the platform the .NET runtime is running in.

As a complement to other answers note that you can also put the lang attribute on various HTML tags inside a page. For example to give a hint to the spellchecker that the input text should be in english:

<input ... spellcheck="true" lang="en"> ...

See: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang

I would recommend storing the time as integers and regulate it through the division and modulo operators, once that is done convert the integers into the string format you require.

I've got a similar message and my problem were some proxy preferences in my settings.xml. So i disabled them and everything works fine.

It must be here, because accepted answer from 2012

In 2018 and modern browsers you can send a custom event from iframe to parent window.

iframe:

var data = { foo: 'bar' }
var event = new CustomEvent('myCustomEvent', { detail: data })
window.parent.document.dispatchEvent(event)

parent:

window.document.addEventListener('myCustomEvent', handleEvent, false)
function handleEvent(e) {
  console.log(e.detail) // outputs: {foo: 'bar'}
}

PS: Of course, you can send events in opposite direction same way.

document.querySelector('#iframe_id').contentDocument.dispatchEvent(event)

The following script works for me for multiple values of $COLUMNS. I wonder if you are not setting COLUMNS prior to this call?

#!/bin/bash
COLUMNS=30
svn diff $@ --diff-cmd /usr/bin/diff -x "-y -w -p -W $COLUMNS"

Can you echo $COLUMNS inside your script to see if it set correctly?

To ignore all untracked files in any submodule use the following command to ignore those changes.

git config --global diff.ignoreSubmodules dirty

It will add the following configuration option to your local git config:

[diff]
  ignoreSubmodules = dirty

I couldn't use any of the suggestions above.
Why I prefer my solution?
This method checks if mouse is over an element at any time chosen by You.
Mouseenter and :hover are cool, but mouseenter triggers only if you move the mouse, not when element moves under the mouse.
:hover is pretty sweet but ... IE

So I do this:

No 1. store mouse x, y position every time it's moved when you need to,
No 2. check if mouse is over any of elements that match the query do stuff ... like trigger a mouseenter event

// define mouse x, y variables so they are traced all the time
var mx = 0; //  mouse X position
var my = 0; //  mouse Y position

// update mouse x, y coordinates every time user moves the mouse
$(document).mousemove(function(e){
    mx = e.pageX;
    my = e.pageY;
});

// check is mouse is over an element at any time You need (wrap it in function if You need to)
$("#my_element").each(function(){
    boxX = $(this).offset().left;
    boxY = $(this).offset().top;
    boxW = $(this).innerWidth();
    boxH = $(this).innerHeight();
    if ((boxX <= mx) &&
        (boxX + 1000 >= mx) &&
        (boxY <= my) &&
        (boxY + boxH >= my))
    {
        // mouse is over it so you can for example trigger a mouseenter event
        $(this).trigger("mouseenter");
    }
});

No, you don't want a generic method. This is much easier:

MyEnum myEnum = (MyEnum)myInt;

MyEnum myEnum = (MyEnum)Enum.Parse(typeof(MyEnum), myString);

I think it will also be faster.

In the code you have posted there would be no advantages, as you are misusing the StringBuilder. You build the same String in both cases. Using StringBuilder you can avoid the + operation on Strings using the append method. You should use it this way:

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

In Java, the String type is an inmutable sequence of characters, so when you add two Strings the VM creates a new String value with both operands concatenated.

StringBuilder provides a mutable sequence of characters, which you can use to concat different values or variables without creating new String objects, and so it can sometimes be more efficient than working with strings

This provides some useful features, as changing the content of a char sequence passed as parameter inside another method, which you can't do with Strings.

private void addWhereClause(StringBuilder sql, String column, String value) {
   //WARNING: only as an example, never append directly a value to a SQL String, or you'll be exposed to SQL Injection
   sql.append(" where ").append(column).append(" = ").append(value);
}

For the case XCode version is lower than iOS device's image, you can either copy the disk image from other already updated XCode(or maybe the internet) or upgrade your XCode.

The image is a folder with size about over 10MB, and place(find or put it) here under this path "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSup??port/".

To enter Xcode.app package, hold control key and click on Xcode.app, you will find additional option like show package content or some word similar. Choose this option and you will enter Xcode.app like entering a normal folder.

Hope it's helpful and good luck!

int a[20];
int length;
length = sizeof(a) / sizeof(int);

and you can use another way to make your code not be hard-coded to int

Say if you have an array array

you just need to:

int len = sizeof(array) / sizeof(array[0]);

Try changing

git checkout -- a

to

git checkout -- `git ls-files -m -- a`

Since version 1.7.0, Git's ls-files honors the skip-worktree flag.

Running your test script (with some minor tweaks changing git commit... to git commit -q and git status to git status --short) outputs:

Initialized empty Git repository in /home/user/repo/.git/
After read-tree:
a/a/aa
a/b/ab

After modifying:

 D a/a/aa
 D a/b/ab
 M b/a/ba
After checkout:
 M b/a/ba
a/a/aa
a/c/ac
a/b/ab
b/a/ba

Running your test script with the proposed checkout change outputs:

Initialized empty Git repository in /home/user/repo/.git/

Control characters:

(Hex codes assume an ASCII-compatible character encoding.)

• \a = \x07 = alert (bell)
• \b = \x08 = backspace
• \t = \x09 = horizonal tab
• \n = \x0A = newline (or line feed)
• \v = \x0B = vertical tab
• \f = \x0C = form feed
• \r = \x0D = carriage return
• \e = \x1B = escape (non-standard GCC extension)

Punctuation characters:

• \" = quotation mark (backslash not required for '"')
• \' = apostrophe (backslash not required for "'")
• \? = question mark (used to avoid trigraphs)
• \\ = backslash

Numeric character references:

• \ + up to 3 octal digits
• \x + any number of hex digits
• \u + 4 hex digits (Unicode BMP, new in C++11)
• \U + 8 hex digits (Unicode astral planes, new in C++11)

\0 = \00 = \000 = octal ecape for null character

If you do want an actual digit character after a \0, then yes, I recommend string concatenation. Note that the whitespace between the parts of the literal is optional, so you can write "\0""0".

I'm late to the party here, but if you're dealing with integers of a fixed length you can just do integer comparison:

SELECT * FROM books WHERE price > 89999 AND price < 90100;

Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:

#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"

The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).

If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.

If you want to roll your own, for just the one specific case, you could do something like this:

if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
    ext_program="${1:7}"
else
    ext_program="default program"
fi

class CurrentValue:

    def __init__(self, value):
        self.value = value

    def set_val(self, k):
        self.value = k

    def get_val(self):
        return self.value


class AddValue:

    def av(self, ocv):
        print('Before:', ocv.get_val())
        num = int(input('Enter number to add : '))
        nnum = num + ocv.get_val()
        ocv.set_val(nnum)
        print('After add :', ocv.get_val())


cvo = CurrentValue(5)

avo = AddValue()

avo.av(cvo)

We define 2 classes, CurrentValue and AddValue We define 3 methods in the first class One init in order to give to the instance variable self.value an initial value A set_val method where we set the self.value to a k A get_val method where we get the valuue of self.value We define one method in the second class A av method where we pass as parameter(ovc) an object of the first class We create an instance (cvo) of the first class We create an instance (avo) of the second class We call the method avo.av(cvo) of the second class and pass as an argument the object we have already created from the first class. So by this way I would like to show how it is possible to call a method of a class from another class.

I am sorry for any inconvenience. This will not happen again.

I used friedmud's answer. I looked into this for a while, and it seems to be a good way to get started. This solution also has a well defined method of adding compiler flags. I answered again, because I made changes to make it work in my environment, Ubuntu and g++. More working examples are the best teacher, sometimes.

appname := myapp

CXX := g++
CXXFLAGS := -Wall -g

srcfiles := $(shell find . -maxdepth 1 -name "*.cpp")
objects  := $(patsubst %.cpp, %.o, $(srcfiles))

all: $(appname)

$(appname): $(objects)
    $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $(appname) $(objects) $(LDLIBS)

depend: .depend

.depend: $(srcfiles)
    rm -f ./.depend
    $(CXX) $(CXXFLAGS) -MM $^>>./.depend;

clean:
    rm -f $(objects)

dist-clean: clean
    rm -f *~ .depend

include .depend

Makefiles seem to be very complex. I was using one, but it was generating an error related to not linking in g++ libraries. This configuration solved that problem.

PowerShell interpolates, does it not?

In PHP

echo "filesizecounter: " . $filesizecounter 

can also be written as:

echo "filesizecounter: $filesizecounter" 

In PowerShell something like this should suit your needs:

Write-Host "filesizecounter: $filesizecounter"

River is a good solution once you want to have a almost real time synchronization and general solution.

If you have data in MongoDB already and want to ship it very easily to Elasticsearch like "one-shot" you can try my package in Node.js https://github.com/itemsapi/elasticbulk.

It's using Node.js streams so you can import data from everything what is supporting streams (i.e. MongoDB, PostgreSQL, MySQL, JSON files, etc)

Example for MongoDB to Elasticsearch:

Install packages:

npm install elasticbulk
npm install mongoose
npm install bluebird

Create script i.e. script.js:

const elasticbulk = require('elasticbulk');
const mongoose = require('mongoose');
const Promise = require('bluebird');
mongoose.connect('mongodb://localhost/your_database_name', {
  useMongoClient: true
});

mongoose.Promise = Promise;

var Page = mongoose.model('Page', new mongoose.Schema({
  title: String,
  categories: Array
}), 'your_collection_name');

// stream query 
var stream = Page.find({
}, {title: 1, _id: 0, categories: 1}).limit(1500000).skip(0).batchSize(500).stream();

elasticbulk.import(stream, {
  index: 'my_index_name',
  type: 'my_type_name',
  host: 'localhost:9200',
})
.then(function(res) {
  console.log('Importing finished');
})

Ship your data:

node script.js

It's not extremely fast but it's working for millions of records (thanks to streams).

This will get you a string array of all the resources:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();

Give the DIV a specific with in percentage or pixels and center it using CSS margin property.

Here is a function that parses without raising errors. It handles obvious cases returns None on failure (handles up to 2000 '-/+' signs by default on CPython!):

#!/usr/bin/env python

def get_int(number):
    splits = number.split('.')
    if len(splits) > 2:
        # too many splits
        return None
    if len(splits) == 2 and splits[1]:
        # handle decimal part recursively :-)
        if get_int(splits[1]) != 0:
            return None

    int_part = splits[0].lstrip("+")
    if int_part.startswith('-'):
        # handle minus sign recursively :-)
        return get_int(int_part[1:]) * -1
    # successful 'and' returns last truth-y value (cast is always valid)
    return int_part.isdigit() and int(int_part)

Some tests:

tests = ["0", "0.0", "0.1", "1", "1.1", "1.0", "-1", "-1.1", "-1.0", "-0", "--0", "---3", '.3', '--3.', "+13", "+-1.00", "--+123", "-0.000"]

for t in tests:
    print "get_int(%s) = %s" % (t, get_int(str(t)))

Results:

get_int(0) = 0
get_int(0.0) = 0
get_int(0.1) = None
get_int(1) = 1
get_int(1.1) = None
get_int(1.0) = 1
get_int(-1) = -1
get_int(-1.1) = None
get_int(-1.0) = -1
get_int(-0) = 0
get_int(--0) = 0
get_int(---3) = -3
get_int(.3) = None
get_int(--3.) = 3
get_int(+13) = 13
get_int(+-1.00) = -1
get_int(--+123) = 123
get_int(-0.000) = 0

For your needs you can use:

def int_predicate(number):
     return get_int(number) is not None

android:gravity handles the alignment of its children,

Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

Jack's answer is perfectly working for click event while longClick is considering is as menu button click.

By the way, if anyone is wondering how to do via kotlin,

class HomeButtonReceiver(private var context: Context,private var listener: OnHomeButtonClickListener) {
    private val mFilter: IntentFilter = IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)
    private var mReceiver: InnerReceiver = InnerReceiver()

    fun startWatch() {
        context.registerReceiver(mReceiver, mFilter)
    }

    fun stopWatch() {
        context.unregisterReceiver(mReceiver)
    }

    inner class InnerReceiver: BroadcastReceiver() {
        private val systemDialogReasonKey = "reason"
        private val systemDialogReasonHomeKey = "homekey"
        override fun onReceive(context: Context?, intent: Intent?) {
            val action = intent?.action
            if (action == Intent.ACTION_CLOSE_SYSTEM_DIALOGS) {
                val reason = intent.getStringExtra(systemDialogReasonKey)
                if (reason != null && reason == systemDialogReasonHomeKey) {
                    listener.onHomeButtonClick()
                }
            }
        }
    } 
}

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

I'm working with

jQuery Autocomplete

I tried looking for an event as described above, but when the request function fires it doesn't seem to be available. I used this.element.attr("id") to get the element's ID instead, and it seems to work fine.

I modified @Geuis 's answer by using lambda and convert it upper case first:

people.sort((a, b) => a.toLocaleUpperCase() < b.toLocaleUpperCase() ? -1 : 1);

As an addendum to b01's answer, the second argument of $.proxy is often used to preserve the this reference. Additional arguments passed to $.proxy are partially applied to the function, pre-filling it with data. Note that any arguments $.post passes to the callback will be applied at the end, so doSomething should have those at the end of its argument list:

function clicked() {
    var myDiv = $("#my-div");
    var callback = $.proxy(doSomething, this, myDiv);
    $.post("someurl.php",someData,callback,"json"); 
}

function doSomething(curDiv, curData) {
    //"this" still refers to the same "this" as clicked()
    var serverResponse = curData;
}

This approach also allows multiple arguments to be bound to the callback:

function clicked() {
    var myDiv = $("#my-div");
    var mySpan = $("#my-span");
    var isActive = true;
    var callback = $.proxy(doSomething, this, myDiv, mySpan, isActive);
    $.post("someurl.php",someData,callback,"json"); 
}

function doSomething(curDiv, curSpan, curIsActive, curData) {
    //"this" still refers to the same "this" as clicked()
    var serverResponse = curData;
}

you can configure the coverage exclusion in the sonar properties, outside of the configuration of the jacoco plugin:

...
<properties>
    ....
    <sonar.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.exclusions>
    <sonar.test.exclusions>
        src/test/**/*
    </sonar.test.exclusions>
    ....
    <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
    <sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
    <sonar.coverage.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.coverage.exclusions>
    <jacoco.version>0.7.5.201505241946</jacoco.version>
    ....
</properties>
....

and remember to remove the exclusion settings from the plugin

SQL Developer 3.1 fixes this issue. Its an early adopter release at the moment though.

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

For publicly access use like below:

public arr: Criminal[] = [];

In HTML5 better use this:

{
//...
canvas.width = img.naturalWidth; //img.width;
canvas.height = img.naturalHeight; //img.height;
//...
}

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

Stackbliz https://stackblitz.com/edit/angular-af55ep

You just need to correct the format of your html

<form>
    <li>Number 1: <input type="text" ng-model="one"/> </li>
    <li>Number 2: <input type="text" ng-model="two"/> </li>
        <li>Total <input type="text" value="{{total()}}"/>  </li>      
    {{total()}}

</form>

"npm install" replaces all dependencies in your node_modules installed with "npm link" with versions from npmjs (specified in your package.json)

Try this:

$(document).ready(function(){
    var yourArray = [];
    $("span.HOEnZb").find("div").each(function(){
        if(($.trim($(this).text()).length>0)){
         yourArray.push($(this).text());
        }
    });
});

DEMO

You absolutely can, I use this approach a lot w/ both JavaScript and PHP.

Field definition:

<input type="hidden" name="foo" value="<?php echo $var;?>" />

Access w/ PHP:

$_GET['foo'] or $_POST['foo']

Also: Don't forget to sanitize your inputs if they are going into a database. Feel free to use my routine: https://github.com/niczak/PHP-Sanitize-Post/blob/master/sanitize.php

Cheers!

We have one more option to do order by

public Cursor getlistbyrank(String rank) {
        try {
//This can be used
return db.`query("tablename", null, null, null, null, null, rank +"DESC",null );
OR
return db.rawQuery("SELECT * FROM table order by rank", null);
        } catch (SQLException sqle) {
            Log.e("Exception on query:-", "" + sqle.getMessage());
            return null;
        }
    }

You can use this two method for order

I assume you don't want to rebind the event, but call the handler.

You can use trigger() to trigger events:

$('#billing_state_id').trigger('change');

If your handler doesn't rely on the event context and you don't want to trigger other handlers for the event, you could also name the function:

function someFunction() {
    //do stuff
}

$(document).ready(function(){
    //Load City by State
    $('#billing_state_id').live('change', someFunction);   
    $('#click_me').live('click', function() {
       //do something
       someFunction();
    });
  });

Also note that live() is deprecated, on() is the new hotness.

I have tried your code in above code don't use [preferences.load(configFile);] statement and it will work.here is running sample code

public static void main(String[]s)
{

    Logger log = Logger.getLogger("MyClass");
    try {
    FileInputStream fis =  new FileInputStream("p.properties");
    LogManager.getLogManager().readConfiguration(fis);
    log.setLevel(Level.FINE);
    log.addHandler(new java.util.logging.ConsoleHandler());
    log.setUseParentHandlers(false);

    log.info("starting myApp");
    fis.close();

    } 
    catch(IOException e) {
    e.printStackTrace();
    }
}

Fully fleshed out example with arrows for only the red edges:

import networkx as nx
import matplotlib.pyplot as plt

G = nx.DiGraph()
G.add_edges_from(
    [('A', 'B'), ('A', 'C'), ('D', 'B'), ('E', 'C'), ('E', 'F'),
     ('B', 'H'), ('B', 'G'), ('B', 'F'), ('C', 'G')])

val_map = {'A': 1.0,
           'D': 0.5714285714285714,
           'H': 0.0}

values = [val_map.get(node, 0.25) for node in G.nodes()]

# Specify the edges you want here
red_edges = [('A', 'C'), ('E', 'C')]
edge_colours = ['black' if not edge in red_edges else 'red'
                for edge in G.edges()]
black_edges = [edge for edge in G.edges() if edge not in red_edges]

# Need to create a layout when doing
# separate calls to draw nodes and edges
pos = nx.spring_layout(G)
nx.draw_networkx_nodes(G, pos, cmap=plt.get_cmap('jet'), 
                       node_color = values, node_size = 500)
nx.draw_networkx_labels(G, pos)
nx.draw_networkx_edges(G, pos, edgelist=red_edges, edge_color='r', arrows=True)
nx.draw_networkx_edges(G, pos, edgelist=black_edges, arrows=False)
plt.show()

If you are using NodeJS, you can use the build-in util function:

import * as util from "util";
util.format('My string: %s', 'foo');

application/xml is seen by svn as binary type whereas text/xml as text file for which a diff can be displayed.

Most of bootstrap datepickers as I write this answer are rather buggy when included in Bootstrap 4. In my view the least code adding solution is a jQuery plugin. I used this one https://plugins.jquery.com/datetimepicker/ - you can see its usage here: https://xdsoft.net/jqplugins/datetimepicker/ It sure is not as smooth as the whole BS interface, but it only requires its css and js files along with jQuery which is already included in bootstrap.

I would encourage you to see this youtube video which demonstrates the difference between C# bin and obj folders and also explains how we get the benefit of incremental/conditional compilation.

C# compilation is a two-step process, see the below diagram for more details:

1. Compiling: In compiling phase individual C# code files are compiled into individual compiled units. These individual compiled code files go in the OBJ directory.
2. Linking: In the linking phase these individual compiled code files are linked to create single unit DLL and EXE. This goes in the BIN directory.

If you compare both bin and obj directory you will find greater number of files in the "obj" directory as it has individual compiled code files while "bin" has a single unit.

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).

use google guava !

Iterable<String> fieldsIterable = ...
List<String> fields = Lists.newArrayList(fieldsIterable);

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

My problem was that my @angular/platform-browser was on version 2.3.1

npm install @angular/platform-browser@latest --save

Upgrading to 4.4.6 did the trick and added /animations folder under node_modules/@angular/platform-browser

I had a similar problem.

I think the problem is that when you try to enclose two or more functions that deals with an array type of variable, php will return an error.

Let's say for example this one.

$data = array('key1' => 'Robert', 'key2' => 'Pedro', 'key3' => 'Jose');

// This function returns the last key of an array (in this case it's $data)
$lastKey = array_pop(array_keys($data));

// Output is "key3" which is the last array.
// But php will return “Strict Standards: Only variables should 
// be passed by reference” error.
// So, In order to solve this one... is that you try to cut 
// down the process one by one like this.

$data1  = array_keys($data);
$lastkey = array_pop($data1);

echo $lastkey;

There you go!

var Timestamp = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds();

Parsing the Feed

With jQuery's jFeed

_{(Don't really recommend that one, see the other options.)}

jQuery.getFeed({
   url     : FEED_URL,
   success : function (feed) {
      console.log(feed.title);
      // do more stuff here
   }
});

With jQuery's Built-in XML Support

$.get(FEED_URL, function (data) {
    $(data).find("entry").each(function () { // or "item" or whatever suits your feed
        var el = $(this);

        console.log("------------------------");
        console.log("title      : " + el.find("title").text());
        console.log("author     : " + el.find("author").text());
        console.log("description: " + el.find("description").text());
    });
});

With jQuery and the Google AJAX Feed API

$.ajax({
  url      : document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(FEED_URL),
  dataType : 'json',
  success  : function (data) {
    if (data.responseData.feed && data.responseData.feed.entries) {
      $.each(data.responseData.feed.entries, function (i, e) {
        console.log("------------------------");
        console.log("title      : " + e.title);
        console.log("author     : " + e.author);
        console.log("description: " + e.description);
      });
    }
  }
});

But that means you're relient on them being online and reachable.

Building Content

Once you've successfully extracted the information you need from the feed, you could create DocumentFragments (with document.createDocumentFragment() containing the elements (created with document.createElement()) you'll want to inject to display your data.

Injecting the content

Select the container element that you want on the page and append your document fragments to it, and simply use innerHTML to replace its content entirely.

Something like:

$('#rss-viewer').append(aDocumentFragmentEntry);

or:

$('#rss-viewer')[0].innerHTML = aDocumentFragmentOfAllEntries.innerHTML;

My simple solution for SQLite (and probably MySQL):

SELECT *, MAX(age) FROM mytable GROUP BY `Group`;

However it doesn't work in PostgreSQL and maybe some other platforms.

In PostgreSQL you can use DISTINCT ON clause:

SELECT DISTINCT ON ("group") * FROM "mytable" ORDER BY "group", "age" DESC;

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

in Symfony 2.3

/app/config/config.yml

framework:
    # ?????? ??????????????? ???????? ? ???????, json, xml ? ???????
    serializer:
        enabled: true

services:
    object_normalizer:
        class: Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer
        tags:
        # ???????? ? ???? ????????? ???? ??????, ??? ??. ?????, ?.?. ????? ???????? ?? ?????
          - { name: serializer.normalizer }

and example for your controller:

/**
 * ????? ???????? ?? ?? ??????? ? ?? ?????
 * @Route("/search/", name="orgunitSearch")
 */
public function orgunitSearchAction()
{
    $array = $this->get('request')->query->all();

    $entity = $this->getDoctrine()
        ->getRepository('IntranetOrgunitBundle:Orgunit')
        ->findOneBy($array);

    $serializer = $this->get('serializer');
    //$json = $serializer->serialize($entity, 'json');
    $array = $serializer->normalize($entity);

    return new JsonResponse( $array );
}

but the problems with the field type \DateTime will remain.

It's usually just easier to skip the mouse altogether--or it would be if Sublime didn't mess up multiselect when word wrapping. Here's the official documentation on using the keyboard and mouse for multiple selection. Since it's a bit spread out, I'll summarize it:

Where shortcuts are different in Sublime Text 3, I've made a note. For v3, I always test using the latest dev build; if you're using the beta build, your experience may be different.

If you lose your selection when switching tabs or windows (particularly on Linux), try using Ctrl + U to restore it.

Mouse

Windows/Linux

Building blocks:

• Positive/negative:
  • Add to selection: Ctrl
  • Subtract from selection: Alt In early builds of v3, this didn't work for linear selection.
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or Shift + Right Click On Linux, middle click pastes instead by default.

Combine as you see fit. For example:

• Add to selection: Ctrl + Left Click (and optionally drag)
• Subtract from selection: Alt + Left Click This didn't work in early builds of v3.
• Add block selection: Ctrl + Shift + Right Click (and drag)
• Subtract block selection: Alt + Shift + Right Click (and drag)

Mac OS X

Building blocks:

• Positive/negative:
  • Add to selection: ?
  • Subtract from selection: ?? (only works with block selection in v3; presumably bug)
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or ? + Left Click

Combine as you see fit. For example:

• Add to selection: ? + Left Click (and optionally drag)
• Subtract from selection: ?? + Left Click (and drag--this combination doesn't work in Sublime Text 3, but supposedly it works in 2)
• Add block selection: ?? + Left Click (and drag)
• Subtract block selection: ??? + Left Click (and drag)

Keyboard

Windows

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Ctrl + Alt + Up/Down
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Linux

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Alt + Up/Down Note that you may be able to hold Ctrl as well to get the same shortcuts as Windows, but Linux tends to use Ctrl + Alt combinations for global shortcuts.
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Mac OS X

• Return to single selection mode: ? (that's the Mac symbol for Escape)
• Extend selection upward/downward at all carets: ^??, ^?? (See note)
• Extend selection leftward/rightward at all carets: ??/??
• Move all carets up/down/left/right and clear selection: ?, ?, ?, ?
• Undo the last selection motion: ?U
• Add next occurrence of selected text to selection: ?D
• Add all occurrences of the selected text to the selection: ^?G
• Rotate between occurrences of selected text (single selection): ??G (reverse: ???G)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: ??L

Notes for Mac users

On Yosemite and El Capitan, ^?? and ^?? are system keyboard shortcuts by default. If you want them to work in Sublime Text, you will need to change them:

1. Open System Preferences.
2. Select the Shortcuts tab.
3. Select Mission Control in the left listbox.
4. Change the keyboard shortcuts for Mission Control and Application windows (or disable them). I use ^?? and ^??. They defaults are ^? and ^?; adding ^ to those shortcuts triggers the same actions, but slows the animations.

In case you're not familiar with Mac's keyboard symbols:

• ? is the escape key
• ^ is the control key
• ? is the option key
• ? is the shift key
• ? is the command key
• ? et al are the arrow keys, as depicted

in ur XCODE (4.3) next the play button :) (run)

select : edit scheme

the scheme management window will open

click on the Arguments tab

you should see : 1- Arguments passed on launch 2- environment variables

inside the the (2- environment variables) place Name: NSZombieEnabled
Value: YES

And its done....

I was given a 400 page pdf file with a table of data that I had to import - luckily no images. Ghostscript worked for me:

gswin64c -sDEVICE=txtwrite -o output.txt input.pdf

The output file was split into pages with headers, etc., but it was then easy to write an app to strip out blank lines, etc, and suck in all 30,000 records. -dSIMPLE and -dCOMPLEX made no difference in this case.

I don't think there's a NULL column value, when rows are returned within a datareader using the column name.

If you do datareader["columnName"].ToString(); it will always give you a value that can be a empty string (String.Empty if you need to compare).

I would use the following and wouldn't worry too much:

employee.FirstName = sqlreader["columnNameForFirstName"].ToString();

The component type of containers like vectors must be assignable. References are not assignable (you can only initialize them once when they are declared, and you cannot make them reference something else later). Other non-assignable types are also not allowed as components of containers, e.g. vector<const int> is not allowed.

In vi(m), check out:

:help 'list'
:help 'listchars' 

I had this problem, but the file was in UTF-8, it was just that somehow on character had come in that was not encoded in UTF-8. To solve the problem I did what is stated in this thread, i.e. I validated the file: How to check whether a file is valid UTF-8?

Basically you run the command:

$ iconv -f UTF-8 your_file -o /dev/null

And if there is something that is not encoded in UTF-8 it will give you the line and row numbers so that you can find it.

On Windows, just check in the windows task manager if there are any other adb processes running.

Or run adb kill-server

If yes, just kill it & then perform the adb start-server command.

I hope, it should solve the problem.

You should remove "style" attribute instead of "display" property :

$("span").removeAttr("style");

Setting the top and left properties to negative values might not be a good workaround if your problem is simply that you're in quirks mode. This can happen if the page is missing a <!DOCTYPE> declaration, causing it to be rendered in quirks mode in IE8. In IE8 Developer Tools, make sure that "Quirks Mode" is not selected under "Document Mode". If it is selected, you may need to add the appropriate <!DOCTYPE> declaration.

Webkit seems to use internally display: table-row-group for the tbody tag. There is currently a bug with setting height to it: https://github.com/w3c/csswg-drafts/issues/476

Let's hope it will be solved soon.

As stated by user2246674, using success and error as parameter of the ajax function is valid.

To be consistent with precedent answer, reading the doc :

Deprecation Notice:

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks will be deprecated in jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

If you are using the callback-manipulation function (using method-chaining for example), use .done(), .fail() and .always() instead of success(), error() and complete().

In addition, if you want to see Sources and Console on one window, go to:

"Customize and control DevTools -> "Show console drawer"

You can also see it here at the right corner:

width: '100%' and alignSelf: 'stretch' didn't work for me. Dimensions didn't suite my task cause I needed to operate on a deeply nested view. Here's what worked for me, if I rewrite your code. I just added some more Views and used flex properties to achieve the needed layout:

  {/* a column */}
  <View style={styles.container}>
    {/* some rows here */}
    <Text style={styles.welcome}>
      Welcome to React Natives
    </Text>
    {/* this row should take all available width */}
    <View style={{ flexDirection: 'row' }}>
      {/* flex 1 makes the view take all available width */}
      <View style={{ flex: 1 }}>
        <Text style={styles.line1}>
          line1
        </Text>
      </View>
      {/* I also had a button here, to the right of the text */}
    </View>
    {/* the rest of the rows */}
    <Text style={styles.instructions}>
      Press Cmd+R to reload,{'\n'}
      Cmd+D or shake for dev menu
    </Text>
  </View>

This error occurs when you don't have enough space in the partition. Usually MYSQL uses /tmp on linux servers. This may happen with some queries because the lookup was either returning a lot of data, or possibly even just sifting through a lot of data creating big temp files.

Edit your /etc/mysql/my.cnf

tmpdir = /your/new/dir

e.g

tmpdir = /var/tmp

Should be allocated with more space than /tmp that is usually in it's own partition.

Update 1

As of Laravel 5.4 those changes are no more needed.

Laravel 5.4 uses the utf8mb4 character set by default, which includes support for storing "emojis" in the database. If you are upgrading your application from Laravel 5.3, you are not required to switch to this character set.

Update 2

Current production MariaDB versions DO NOT support this setting by default globally. It is implemented in MariaDB 10.2.2+ by default.

Solution

And if you intentionally want to use the correct future-default (starting from Laravel 5.4) UTF8 multi-byte utf8mb4 support for then start to fix your database configuration.

In Laravel config/database.php define:

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',

DYNAMIC allows to store long key indexes.

Server settings (by default included in MySQL 5.7.7+ / MariaDB 10.2.2+):

[mysqld]
# default character set and collation
collation-server = utf8mb4_unicode_ci
character-set-server = utf8mb4

# utf8mb4 long key index
innodb_large_prefix = 1
innodb_file_format = barracuda
innodb_file_format_max = barracuda
innodb_file_per_table = 1

For clients:

[mysql]
default-character-set=utf8mb4

And then STOP your MySQL/MariaDB server. After that START. Hot RESTART may not work.

sudo systemctl stop mysqld
sudo systemctl start mysqld

Now you have Laravel 5.x with UTF8 support.

Here is how to make one:

Here are some inspiration examples:

            try

                cmd = new SqlCommand("RETRIEVE_EMPLOYEE", pl.ConnOpen());
                cmd.Parameters.Add(new SqlParameter("@EMPLOYEENO", employeeNo));
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(dt);
                dataGridView1.DataSource = dt;
            }
            catch (Exception x)
            {
                MessageBox.Show(x.GetBaseException().ToString(), "Error",
                        MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
                cmd.Dispose();
                pl.MySQLConn.Close();
            }
            return dt;
        }

disabling of mat form fields is exempted if you are using form validation,so do make sure that your form field does not have any validations like(validators.required),this worked for me. for ex:

editUserPhone: new FormControl({value:' ',disabled:true})

this makes the phone numbers of user to be non editable.

Netty also provides a nice query string parser called QueryStringDecoder. In one line of code, it can parse the URL in the question. I like because it doesn't require catching or throwing java.net.MalformedURLException.

In one line:

Map<String, List<String>> parameters = new QueryStringDecoder(url).parameters();

See javadocs here: https://netty.io/4.1/api/io/netty/handler/codec/http/QueryStringDecoder.html

Here is a short, self contained, correct example:

import io.netty.handler.codec.http.QueryStringDecoder;
import org.apache.commons.lang3.StringUtils;

import java.util.List;
import java.util.Map;

public class UrlParse {

  public static void main(String... args) {
    String url = "https://google.com.ua/oauth/authorize?client_id=SS&response_type=code&scope=N_FULL&access_type=offline&redirect_uri=http://localhost/Callback";
    QueryStringDecoder decoder = new QueryStringDecoder(url);
    Map<String, List<String>> parameters = decoder.parameters();
    print(parameters);
  }

  private static void print(final Map<String, List<String>> parameters) {
    System.out.println("NAME               VALUE");
    System.out.println("------------------------");
    parameters.forEach((key, values) ->
        values.forEach(val ->
            System.out.println(StringUtils.rightPad(key, 19) + val)));
  }
}

which generates

NAME               VALUE
------------------------
client_id          SS
response_type      code
scope              N_FULL
access_type        offline
redirect_uri       http://localhost/Callback

You should use backspace '\r' or ('\x08') char to go back on previous position in console output

Python 2+:

def backspace(n):
    sys.stdout.write((b'\x08' * n).decode()) # use \x08 char to go back   

for i in range(101):                        # for 0 to 100
    s = str(i) + '%'                        # string for output
    sys.stdout.write(s)                     # just print
    sys.stdout.flush()                      # needed for flush when using \x08
    backspace(len(s))                       # back n chars    
    time.sleep(0.2)                         # sleep for 200ms

Python 3:

import time   

def backline():        
    print('\r', end='')                     # use '\r' to go back


for i in range(101):                        # for 0 to 100
    s = str(i) + '%'                        # string for output
    print(s, end='')                        # just print and flush
    backline()                              # back to the beginning of line    
    time.sleep(0.2)                         # sleep for 200ms

This code will count from 0% to 100% on one line. Final value will be:

> python test.py
100%

Additional info about flush in this case here: Why do python print statements that contain 'end=' arguments behave differently in while-loops?

 $(document).ready(function () {
    $.ajax({ 
        url: '/functions.php', 
        type: 'GET',
        data: { get_param: 'value' }, 
        success: function (data) { 
         for (var i=0;i<data.length;++i)
         {
         $('#cand').append('<div class="name">data[i].name</>');
         }
        }
    });
});

You want to use regexp_substr() for this. This should work for your example:

select regexp_substr(val, '[^/]+/[^/]+', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

Here, by the way, is the SQL Fiddle.

Oops. I missed the part of the question where it says the last delimiter. For that, we can use regex_replace() for the first part:

select regexp_replace(val, '/[^/]+$', '', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

And here is this corresponding SQL Fiddle.
