Programs & Examples On #Indesign server

It is working for me

ng g component component-name --skip-import

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

Cron is good for something that will run periodically, like every Saturday at 4am. There's also anacron, which works around power shutdowns, sleeps, and whatnot. As well as at.

But for a one-off solution, that doesn't require root or anything, you can just use date to compute the seconds-since-epoch of the target time as well as the present time, then use expr to find the difference, and sleep that many seconds.

Type "gg" in command mode. This brings the cursor to the first line.

Just for those interested you can avoid writing custom function by passing NULL as last parameter (if you do not intend to do extra processing of returned data).
In this case default internal function is used.

Method call setSelectedIndex("item_value"); doesn't work because setSelectedIndex use sequential index.

Just for those who want to get $setPristine without having to upgrade to v1.1.x, here is the function I used to simulate the $setPristine function. I was reluctant to use the v1.1.5 because one of the AngularUI components I used is no compatible.

var setPristine = function(form) {
    if (form.$setPristine) {//only supported from v1.1.x
        form.$setPristine();
    } else {
        /*
         *Underscore looping form properties, you can use for loop too like:
         *for(var i in form){ 
         *  var input = form[i]; ...
         */
        _.each(form, function (input) {
            if (input.$dirty) {
                input.$dirty = false;
            }
        });
    }
};

Note that it ONLY makes $dirty fields clean and help changing the 'show error' condition like $scope.myForm.myField.$dirty && $scope.myForm.myField.$invalid.

Other parts of the form object (like the css classes) still need to consider, but this solve my problem: hide error messages.

Simple Difference: (Inspired by Yaakov's Coursera AngularJS course)

MVC (Model View Controller)

1. Models: Models contain data information. Does not call or use Controller and View. Contains the business logic and ways to represent data. Some of this data, in some form, may be displayed in the view. It can also contain logic to retrieve the data from some source.
2. Controller: Acts as the connection between view and model. View calls Controller and Controller calls the model. It basically informs the model and/or the view to change as appropriate.
3. View: Deals with UI part. Interacts with the user.

MVVM (Model View View Model)

ViewModel:

1. It is the representation of the state of the view.
2. It holds the data that’s displayed in the view.
3. Responds to view events, aka presentation logic.
4. Calls other functionalities for business logic processing.
5. Never directly asks the view to display anything.

• As the name suggested, var is variable without any data type.
• If you don't know which type of data will be returned by any method, such cases are good for using var.
• var is Implicit type which means system will define the data type itself. The compiler will infer its type based on the value to the right of the "=" operator.
• int/string etc. are the explicit types as it is defined by you explicitly.
• Var can only be defined in a method as a local variable
• Multiple vars cannot be declared and initialized in a single statement. For example, var i=1, j=2; is invalid.

int i = 100;// explicitly typed 
var j = 100; // implicitly typed

The selected answer is only for Safari. At the moment it's not possible to do real remote debugging in Chrome on iOS, but as with most mobile browsers you can use WeInRe for some simple debugging. It's a bit work to set up, but lets you inspect the DOM, see styling, change DOM and play with the console.

To setup:

• Install nodejs
• npm install -g weinre
• weinre --boundHost -all-
• Open http://{wifi-ip-address}:8080/ and copy the target script code
• Paste the script tag into your page (or use the bookmarklet)
• Click on the link to the debug client user interface (http://{wifi-ip-address}:8080/client/#anonymous)
• When you get a green line under Clients the browser is connected

The bookmarklet is a bit more of an hassle to install. It's easiest if you have bookmark-sync turned on for both desktop and mobile Chrome. Copy the bookmarklet url from the local weinre server (same as above). Unfortunately it doesn't work because it's not url-encoded properly. So open the JavaScript console and type in:

copy(encodeURI('')); // paste bookmarklet inside quotes

You should now have the url-encoded bookmarklet in your clipboard. Paste it into a new bookmark under Mobile Bookmarks. Call it weinre or something simple to type. It should be synced to your mobile pretty fast, so load the page you want to inspect. Then type in the bookmark name in the url-bar, and you should see the bookmarklet as an auto-complete-suggestion. Click it to run bookmarklet code :)

Try this:

INSERT INTO prices (
    group, 
    id,
    price
) 
SELECT
    7,
    articleId,
    1.50
FROM
    article 
WHERE 
    name LIKE 'ABC%';

To make a vertical line, just use a rectangle with width of 1dp:

<shape>
    <size
        android:width="1dp"
        android:height="16dp" />
    <solid
        android:color="#c8cdd2" />
</shape>

Don't use stroke, use solid (which is the "fill" color) to specify the color of the line.

Why do people always use jQuery when it isn't necessary?
Why can't people just use simple JavaScript?

var ele = /*Your Form Element*/;
if(ele.addEventListener){
    ele.addEventListener("submit", callback, false);  //Modern browsers
}else if(ele.attachEvent){
    ele.attachEvent('onsubmit', callback);            //Old IE
}

callback is a function that you want to call when the form is being submitted.

About EventTarget.addEventListener, check out this documentation on MDN.

To cancel the native submit event (prevent the form from being submitted), use .preventDefault() in your callback function,

document.querySelector("#myForm").addEventListener("submit", function(e){
    if(!isValid){
        e.preventDefault();    //stop form from submitting
    }
});

Listening to the submit event with libraries

If for some reason that you've decided a library is necessary (you're already using one or you don't want to deal with cross-browser issues), here's a list of ways to listen to the submit event in common libraries:

1. jQuery

   $(ele).submit(callback);
   

   Where ele is the form element reference, and callback being the callback function reference. Reference

    <iframe width="100%" height="100%" src="http://jsfiddle.net/DerekL/wnbo1hq0/show" frameborder="0"></iframe>

2. AngularJS (1.x)

   <form ng-submit="callback()">
   
   $scope.callback = function(){ /*...*/ };
   

   Very straightforward, where $scope is the scope provided by the framework inside your controller. Reference

3. React

   <form onSubmit={this.handleSubmit}>
   
   class YourComponent extends Component {
       // stuff
   
       handleSubmit(event) {
           // do whatever you need here
   
           // if you need to stop the submit event and 
           // perform/dispatch your own actions
           event.preventDefault();
       }
   
       // more stuff
   }
   

   Simply pass in a handler to the onSubmit prop. Reference

4. Other frameworks/libraries

   Refer to the documentation of your framework.

Validation

You can always do your validation in JavaScript, but with HTML5 we also have native validation.

<!-- Must be a 5 digit number -->
<input type="number" required pattern="\d{5}">

You don't even need any JavaScript! Whenever native validation is not supported, you can fallback to a JavaScript validator.

Although building the URL or using tools is still possible, it is not needed anymore.

https://www.nuget.org/ currently has a download link named "Download package", that is available even if you don't have an account on the site.

(at the bottom of the right column).

Example of EntityFramework's detail page: https://www.nuget.org/packages/EntityFramework/: (Updated after comment of kwitee.)

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

to validate the email string you will need to write a regular expression to check it is in the correct form. there are plenty out on the web but be carefull as some can exclude what are actually legal addresses.

essentially it will look something like this

^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$

Actually checking if the email exists and doesn't bounce would mean sending an email and seeing what the result was. i.e. it bounced or it didn't. However it might not bounce for several hours or not at all and still not be a "real" email address. There are a number of services out there which purport to do this for you and would probably be paid for by you and quite frankly why bother to see if it is real?

It is good to check the user has not misspelt their email else they could enter it incorrectly, not realise it and then get hacked of with you for not replying. However if someone wants to add a bum email address there would be nothing to stop them creating it on hotmail or yahoo (or many other places) to gain the same end.

So do the regular expression and validate the structure but forget about validating against a service.

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

I ran into this scenario recently (well over 7 million rows) and eneded up using sqlcmd via powershell (after parsing raw data into SQL insert statements) in segments of 5,000 at a time (SQL can't handle 7 million lines in one lump job or even 500,000 lines for that matter unless its broken down into smaller 5K pieces. You can then run each 5K script one after the other.) as I needed to leverage the new sequence command in SQL Server 2012 Enterprise. I couldn't find a programatic way to insert seven million rows of data quickly and efficiently with said sequence command.

Secondly, one of the things to look out for when inserting a million rows or more of data in one sitting is the CPU and memory consumption (mostly memory) during the insert process. SQL will eat up memory/CPU with a job of this magnitude without releasing said processes. Needless to say if you don't have enough processing power or memory on your server you can crash it pretty easily in a short time (which I found out the hard way). If you get to the point to where your memory consumption is over 70-75% just reboot the server and the processes will be released back to normal.

I had to run a bunch of trial and error tests to see what the limits for my server was (given the limited CPU/Memory resources to work with) before I could actually have a final execution plan. I would suggest you do the same in a test environment before rolling this out into production.

I had this problem, but none of the solutions above worked. I could clone and fetch but couldn't push. Eventually, I figured out the problem was in the url in my .git/config, it should be:

[email protected]:<username>/<project>

(not ssh://github.com/<username>/<project>.git or https://github.com/<username>/<project>.git).

You can compare class tokens to each other, so you could use value.getClass() == Integer.class. However, the simpler and more canonical way is to use instanceof :

    if (value instanceof Integer) {
        System.out.println("This is an Integer");
    } else if(value instanceof String) {
        System.out.println("This is a String");
    } else if(value instanceof Float) {
        System.out.println("This is a Float");
    }

Notes:

• the only difference between the two is that comparing class tokens detects exact matches only, while instanceof C matches for subclasses of C too. However, in this case all the classes listed are final, so they have no subclasses. Thus instanceof is probably fine here.

• as JB Nizet stated, such checks are not OO design. You may be able to solve this problem in a more OO way, e.g.

  System.out.println("This is a(n) " + value.getClass().getSimpleName());
  

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

It is also used for debugging purposes.

Here is a handy list of some of these values:

http://en.wikipedia.org/wiki/Magic_number_%28programming%29#Magic_debug_values

Based upon dwanderson's helpful comment, I was able to do this in a Bash one-liner:

conda create --name envpython2 --file <(conda list -n env1 -e )

My badly named env was "env1" and the new one I wish to clone from it is "envpython2".

I had same problem after updating java. Then I paste

-vm
C:\Program Files\Java\jre6\bin\javaw.exe

to show the path of javaw.exe in eclipse.ini file.

Hope this will help you.

At lest in my case the problem was on the client that tries to fetch the results.

Wanted to get a .csv with ALL the results.

I found the solution by using

psql -U postgres -d dbname  -c "COPY (SELECT * FROM T) TO STDOUT WITH DELIMITER ','"

(where dbname the name of the db...) and redirecting to a file.

Use this code to create suitable parameter from your type:

private SqlParameter GenerateTypedParameter(string name, object typedParameter)
{
    DataTable dt = new DataTable();

    var properties = typedParameter.GetType().GetProperties().ToList();
    properties.ForEach(p =>
    {
        dt.Columns.Add(p.Name, Nullable.GetUnderlyingType(p.PropertyType) ?? p.PropertyType);
    });
    var row = dt.NewRow();
    properties.ForEach(p => { row[p.Name] = (p.GetValue(typedParameter) ?? DBNull.Value); });
    dt.Rows.Add(row);

    return new SqlParameter
    {
        Direction = ParameterDirection.Input,
        ParameterName = name,
        Value = dt,
        SqlDbType = SqlDbType.Structured
    };
}

UPDATE

This answer was submitted when Angular 2 was still in alpha and many of the features were unavailable / undocumented. While the below will still work, this method is now entirely outdated. I strongly recommend the accepted answer over the below.

Original Answer

Yes in fact it is, however you will want to make sure that it is scoped correctly. For this I've used a property to ensure that this means what I want it to.

@Component({
  ...
  template: '<child [myCallback]="theBoundCallback"></child>',
  directives: [ChildComponent]
})
export class ParentComponent{
  public theBoundCallback: Function;

  public ngOnInit(){
    this.theBoundCallback = this.theCallback.bind(this);
  }

  public theCallback(){
    ...
  }
}

@Component({...})
export class ChildComponent{
  //This will be bound to the ParentComponent.theCallback
  @Input()
  public myCallback: Function; 
  ...
}

You had it right, just put a space between the ! and the [[ like if ! [[

Stopwatch is designed for this purpose and is one of the best way to measure execution time in .NET.

var watch = System.Diagnostics.Stopwatch.StartNew();
/* the code that you want to measure comes here */
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

Do not use DateTimes to measure execution time in .NET.

you have to change your session.save_path setting to the accessible dir, /tmp/ for example

How to change: http://php.net/session_save_path

Being on the shared host, it is advised to set your session save path inside of your home directory but below document root

also note that

• using ob_start is unnecessary here,
• and I am sure you put @ operator by accident and already going to remove it forever, don't you?

That's known as an Arrow Function, part of the ECMAScript 2015 spec...

var foo = ['a', 'ab', 'abc'];_x000D_
_x000D_
var bar = foo.map(f => f.length);_x000D_
_x000D_
console.log(bar); // 1,2,3

Shorter syntax than the previous:

// < ES6:_x000D_
var foo = ['a', 'ab', 'abc'];_x000D_
_x000D_
var bar = foo.map(function(f) {_x000D_
  return f.length;_x000D_
});_x000D_
console.log(bar); // 1,2,3

DEMO

The other awesome thing is lexical this... Usually, you'd do something like:

function Foo() {_x000D_
  this.name = name;_x000D_
  this.count = 0;_x000D_
  this.startCounting();_x000D_
}_x000D_
_x000D_
Foo.prototype.startCounting = function() {_x000D_
  var self = this;_x000D_
  setInterval(function() {_x000D_
    // this is the Window, not Foo {}, as you might expect_x000D_
    console.log(this); // [object Window]_x000D_
    // that's why we reassign this to self before setInterval()_x000D_
    console.log(self.count);_x000D_
    self.count++;_x000D_
  }, 1000)_x000D_
}_x000D_
_x000D_
new Foo();

But that could be rewritten with the arrow like this:

function Foo() {_x000D_
  this.name = name;_x000D_
  this.count = 0;_x000D_
  this.startCounting();_x000D_
}_x000D_
_x000D_
Foo.prototype.startCounting = function() {_x000D_
  setInterval(() => {_x000D_
    console.log(this); // [object Object]_x000D_
    console.log(this.count); // 1, 2, 3_x000D_
    this.count++;_x000D_
  }, 1000)_x000D_
}_x000D_
_x000D_
new Foo();

I was facing the same issue. I added the scrollX: true property for the dataTable and it worked. There is no need to change the CSS for datatable

jQuery('#myTable').DataTable({
                            "fixedHeader":true,
                            "scrollY":"450px",
                            "scrollX":true,
                            "paging":   false,
                            "ordering": false,
                            "info":     false,
                            "searching": false,
                            "scrollCollapse": true
                            });

In c# following code insert data into datatable on specified position

DataTable dt = new DataTable();
dt.Columns.Add("SL");
dt.Columns.Add("Amount");

dt.rows.add(1, 1000)
dt.rows.add(2, 2000)

dt.Rows.InsertAt(dt.NewRow(), 3);

var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;

You can first read the whole content of file into a String.

FileInputStream fileInputStream = null;
String data="";
StringBuffer stringBuffer = new StringBuffer("");
try{
    fileInputStream=new FileInputStream(filename);
    int i;
    while((i=fileInputStream.read())!=-1)
    {
        stringBuffer.append((char)i);
    }
    data = stringBuffer.toString();
}
catch(Exception e){
        LoggerUtil.printStackTrace(e);
}
finally{
    if(fileInputStream!=null){  
        fileInputStream.close();
    }
}

Now You will have the whole content into String ( data variable ).

JSONParser parser = new JSONParser();
org.json.simple.JSONArray jsonArray= (org.json.simple.JSONArray) parser.parse(data);

After that you can use jsonArray as you want.

As this question comes up first on Google I thought I'd share a solution using TigerVNC which is the default these days.

xrandr allows selecting the display modes (a.k.a resolutions) however due to modelines being hard coded any additional modeline such as "2560x1600" or "1600x900" would need to be added into the code. I think the developers who wrote the code are much smarter and the hard coded list is just a sample of values. It leads to the conclusion that there must be a way to add custom modelines and man xrandr confirms it.

With that background if the goal is to share a VNC session between two computers with the above resolutions and assuming that the VNC server is the computer with the resolution of "1600x900":

1. Start a VNC session with a geometry matching the physical display:

   $ vncserver -geometry 1600x900 :1
   

2. On the "2560x1600" computer start the VNC viewer (I prefer Remmina) and connect to the remote VNC session:

   host:5901
   

3. Once inside the VNC session start up a terminal window.

4. Confirm that the new geometry is available in the VNC session:

   $ xrandr
   Screen 0: minimum 32 x 32, current 1600 x 900, maximum 32768 x 32768
   VNC-0 connected 1600x900+0+0 0mm x 0mm
      1600x900      60.00 +
      1920x1200     60.00  
      1920x1080     60.00  
      1600x1200     60.00  
      1680x1050     60.00  
      1400x1050     60.00  
      1360x768      60.00  
      1280x1024     60.00  
      1280x960      60.00  
      1280x800      60.00  
      1280x720      60.00  
      1024x768      60.00  
      800x600       60.00  
      640x480       60.00  
   

   and you'll notice the screen being quite small.

5. List the modeline (see xrandr article in ArchLinux wiki) for the "2560x1600" resolution:

   $ cvt 2560 1600
   # 2560x1600 59.99 Hz (CVT 4.10MA) hsync: 99.46 kHz; pclk: 348.50 MHz
   Modeline "2560x1600_60.00"  348.50  2560 2760 3032 3504  1600 1603 1609 1658 -hsync +vsync
   

   or if the monitor is old get the GTF timings:

   $ gtf 2560 1600 60
   # 2560x1600 @ 60.00 Hz (GTF) hsync: 99.36 kHz; pclk: 348.16 MHz
   Modeline "2560x1600_60.00"  348.16  2560 2752 3032 3504  1600 1601 1604 1656 -HSync +Vsync
   

6. Add the new modeline to the current VNC session:

   $ xrandr --newmode "2560x1600_60.00"  348.16  2560 2752 3032 3504  1600 1601 1604 1656 -HSync +Vsync
   

7. In the above xrandr output look for the display name on the second line:

   VNC-0 connected 1600x900+0+0 0mm x 0mm
   

8. Bind the new modeline to the current VNC virtual monitor:

   $ xrandr --addmode VNC-0 "2560x1600_60.00"
   

9. Use it:

   $ xrandr -s "2560x1600_60.00"
   

Got better solution:

$('#element').resizable({
    stop: function( event, ui ) {
        $('#element').height(ui.originalSize.height);
    }
});

if echo $var | egrep -q '^[0-9]+$'; then
    # $var is a number
else
    # $var is not a number
fi

With Matplotlib prior to version 1.0.1, show() should only be called once per program, even if it seems to work within certain environments (some backends, on some platforms, etc.).

The relevant drawing function is actually draw():

import matplotlib.pyplot as plt

plt.plot(range(10))  # Creates the plot.  No need to save the current figure.
plt.draw()  # Draws, but does not block
raw_input()  # This shows the first figure "separately" (by waiting for "enter").

plt.figure()  # New window, if needed.  No need to save it, as pyplot uses the concept of current figure
plt.plot(range(10, 20))
plt.draw()
# raw_input()  # If you need to wait here too...

# (...)

# Only at the end of your program:
plt.show()  # blocks

It is important to recognize that show() is an infinite loop, designed to handle events in the various figures (resize, etc.). Note that in principle, the calls to draw() are optional if you call matplotlib.ion() at the beginning of your script (I have seen this fail on some platforms and backends, though).

I don't think that Matplotlib offers a mechanism for creating a figure and optionally displaying it; this means that all figures created with figure() will be displayed. If you only need to sequentially display separate figures (either in the same window or not), you can do like in the above code.

Now, the above solution might be sufficient in simple cases, and for some Matplotlib backends. Some backends are nice enough to let you interact with the first figure even though you have not called show(). But, as far as I understand, they do not have to be nice. The most robust approach would be to launch each figure drawing in a separate thread, with a final show() in each thread. I believe that this is essentially what IPython does.

The above code should be sufficient most of the time.

PS: now, with Matplotlib version 1.0.1+, show() can be called multiple times (with most backends).

The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.

var parseXml;
if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

Example usage:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

Which I got from https://stackoverflow.com/a/8412989/1232175.

Take a look here: http://longgoldenears.blogspot.com/2007/09/triple-equals-in-javascript.html

The 3 equal signs mean "equality without type coercion". Using the triple equals, the values must be equal in type as well.

0 == false   // true
0 === false  // false, because they are of a different type
1 == "1"     // true, automatic type conversion for value only
1 === "1"    // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false

In VB code, when trying to submit an INSERT query, you must submit a double query in the same 'executenonquery' like this:

sqlQuery = "SET IDENTITY_INSERT dbo.TheTable ON; INSERT INTO dbo.TheTable (Col1, COl2) VALUES (Val1, Val2); SET IDENTITY_INSERT dbo.TheTable OFF;"

I used a ; separator instead of a GO.

Works for me. Late but efficient!

I tried with a rest client.

it works fine. I retrieve 200 OK with a good body.

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.

Looks like someone else found it: What are the default font characteristics in Android ?

There someone discovered the default text size, for TextViews (which use TextAppearance.Small) it's 14sp.

you could use fopen() function.

some example:

$url = 'http://doman.com/path/to/file.mp4';
$destination_folder = $_SERVER['DOCUMENT_ROOT'].'/downloads/';


    $newfname = $destination_folder .'myfile.mp4'; //set your file ext

    $file = fopen ($url, "rb");

    if ($file) {
      $newf = fopen ($newfname, "a"); // to overwrite existing file

      if ($newf)
      while(!feof($file)) {
        fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );

      }
    }

    if ($file) {
      fclose($file);
    }

    if ($newf) {
      fclose($newf);
    }

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

BEGIN TRANSACTION [Tran1]

  BEGIN TRY

      INSERT INTO [Test].[dbo].[T1] ([Title], [AVG])
      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

      ROLLBACK TRANSACTION [Tran1]

  END CATCH  

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

From dictionary.reference.com:

Computers. to analyze (a string of characters) in order to associate groups of characters with the syntactic units of the underlying grammar.

The context of the definition is the translation of program text or a language in the general sense into its component parts with respect to a defined grammar -- turning program text into code. In the context of a particular language keyword, though, it generally means to convert the string value of a fundamental data type into an internal representation of that data type. For example, the string "10" becomes the number (integer) 10.

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

This works and tells you which properties are circular. It also allows for reconstructing the object with the references

  JSON.stringifyWithCircularRefs = (function() {
    const refs = new Map();
    const parents = [];
    const path = ["this"];

    function clear() {
      refs.clear();
      parents.length = 0;
      path.length = 1;
    }

    function updateParents(key, value) {
      var idx = parents.length - 1;
      var prev = parents[idx];
      if (prev[key] === value || idx === 0) {
        path.push(key);
        parents.push(value);
      } else {
        while (idx-- >= 0) {
          prev = parents[idx];
          if (prev[key] === value) {
            idx += 2;
            parents.length = idx;
            path.length = idx;
            --idx;
            parents[idx] = value;
            path[idx] = key;
            break;
          }
        }
      }
    }

    function checkCircular(key, value) {
      if (value != null) {
        if (typeof value === "object") {
          if (key) { updateParents(key, value); }

          let other = refs.get(value);
          if (other) {
            return '[Circular Reference]' + other;
          } else {
            refs.set(value, path.join('.'));
          }
        }
      }
      return value;
    }

    return function stringifyWithCircularRefs(obj, space) {
      try {
        parents.push(obj);
        return JSON.stringify(obj, checkCircular, space);
      } finally {
        clear();
      }
    }
  })();

To reconstruct call JSON.parse() then loop through the properties looking for the [Circular Reference] tag. Then chop that off and... eval... it with this set to the root object.

Don't eval anything that can be hacked. Better practice would be to do string.split('.') then lookup the properties by name to set the reference.

If your system is Posix.2 compliant it should supply the printf utility:

$ printf "print 'zap'\nfor r in range(3): print 'rob'" | python
zap
rob
rob
rob

You'll get converting errors with:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

Use instead:

string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
    found = true; 
} else {
    found = false; 
}

I created this (swift) class to create a back button exactly like the regular one, including back arrow. It can create a button with regular text or with an image.

Usage

weak var weakSelf = self

// Assign back button with back arrow and text (exactly like default back button)
navigationItem.leftBarButtonItems = CustomBackButton.createWithText("YourBackButtonTitle", color: UIColor.yourColor(), target: weakSelf, action: #selector(YourViewController.tappedBackButton))

// Assign back button with back arrow and image
navigationItem.leftBarButtonItems = CustomBackButton.createWithImage(UIImage(named: "yourImageName")!, color: UIColor.yourColor(), target: weakSelf, action: #selector(YourViewController.tappedBackButton))

func tappedBackButton() {

    // Do your thing

    self.navigationController!.popViewControllerAnimated(true)
}

One more place where minSdkVersion makes a sense is a flavor:

productFlavors {
    dev {
        minSdkVersion 22
    }
    prod {
        minSdkVersion 9
    }
}

minSdkVersion (22) will not install on development devices with API level older than 22.

Best and shortest way in my opinion for onchange events on the dropdown to get the selected option:

$('option:selected',this);

to get the value attribute:

$('option:selected',this).attr('value');

to get the shown part between the tags:

$('option:selected',this).text();

In your sample:

$("#select-id").change(function(){
  var cur_value = $('option:selected',this).text();
});

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

Runtime basically means when program interacts with the hardware and operating system of a machine. C does not have it's own runtime but instead, it requests runtime from an operating system (which is basically a part of ram) to execute itself.

You can use the -executable test flag:

-executable
              Matches files which are executable  and  directories  which  are
              searchable  (in  a file name resolution sense).

Your UITableViewDelegate should implement tableView:heightForRowAtIndexPath:

Objective-C

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return [indexPath row] * 20;
}

Swift 5

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return indexPath.row * 20
}

You will probably want to use NSString's sizeWithFont:constrainedToSize:lineBreakMode: method to calculate your row height rather than just performing some silly math on the indexPath :)

Move your map variable into a scope where the event listener can use it. You are creating the map inside your initialize() function and nothing else can use it when created that way.

var map; //<-- This is now available to both event listeners and the initialize() function
function initialize() {
  var mapOptions = {
   center: new google.maps.LatLng(40.5472,12.282715),
   zoom: 6,
   mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("map-canvas"),
            mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", function() {
 var center = map.getCenter();
 google.maps.event.trigger(map, "resize");
 map.setCenter(center); 
});

Please note, buttons and other elements in API 21 and greater have a high elevation, and therefore ignore the xml order of elements regardless of parent layout. Took me a while to figure that one out.

The only easy solution that I have applied is to recreate the primary condition that do the highlights as an IF condition and use it on the IF formula. Something like this. Depending on the highlight condition the formula will change but I think that should be recreated (es. highlight greater than 20).

=IF(B3>20,(B3)," ")

This question seems to be ambiguous.

I'll try with my interpretation of the request.

def do_something(data)
   puts "Found! #{data}"
end

a = { 'x' => 'test', 'y' => 'foo', 'z' => 'bar' }
a.each { |key,value| do_something(value) if key == 'x' }

This will loop over all the key,value pairs and do something only if the key is 'x'.

Ironically, I have what you want, but want something closer to what you had.

I am loading things in dynamically and asynchronously, but with an load callback like so (using dojo and xmlhtpprequest)

  dojo.xhrGet({
    url: 'getCode.php',
    handleAs: "javascript",
    content : {
    module : 'my.js'
  },
  load: function() {
    myFunc1('blarg');
  },
  error: function(errorMessage) {
    console.error(errorMessage);
  }
});

For a more detailed explanation, see here

The problem is that somewhere along the line the code gets evaled, and if there's anything wrong with your code, the console.error(errorMessage); statement will indicate the line where eval() is, not the actual error. This is SUCH a big problem that I am actually trying to convert back to <script> statements (see here.

You should add "throws IOException" to your main method:

public static void main(String[] args) throws IOException {

You can read a bit more about checked exceptions (which are specific to Java) in JLS.

You can do this.

bonus_rows = []
for a in myarr:
  if somecond(a):
      bonus_rows.append(newObj())
myarr.extend( bonus_rows )

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

Details

In vb.net you can actually compare strings with =. Even though String is a reference type, in vb.net = on String has been redefined to do a case-sensitive comparison of contents of the two strings.

You can test this with the following code. Note that I have taken one of the values from user input to ensure that the compiler cannot use the same reference for the two variables like the Java compiler would if variables were defined from the same string Literal. Run the program, type "This" and press <Enter>.

Sub Main()
    Dim a As String = New String("This")
    Dim b As String

    b = Console.ReadLine()

    If a = b Then
        Console.WriteLine("They are equal")
    Else
        Console.WriteLine("Not equal")
    End If
    Console.ReadLine()
End Sub

html5rocks.com has a very good tutorial on this stuff, and this might be a little late, but I myself didn't know this existed. w3schools also has a way to do this using their new library called w3.js. The thing is, this requires the use of a web server and and HTTPRequest object. You can't actually load these locally and test them on your machine. What you can do though, is use polyfills provided on the html5rocks link at the top, or follow their tutorial. With a little JS magic, you can do something like this:

 var link = document.createElement('link');
 if('import' in link){
     //Run import code
     link.setAttribute('rel','import');
     link.setAttribute('href',importPath);
     document.getElementsByTagName('head')[0].appendChild(link);
     //Create a phantom element to append the import document text to
     link = document.querySelector('link[rel="import"]');
     var docText = document.createElement('div');
     docText.innerHTML = link.import;
     element.appendChild(docText.cloneNode(true));
 } else {
     //Imports aren't supported, so call polyfill
     importPolyfill(importPath);
 }

This will make the link (Can change to be the wanted link element if already set), set the import (unless you already have it), and then append it. It will then from there take that and parse the file in HTML, and then append it to the desired element under a div. This can all be changed to fit your needs from the appending element to the link you are using. I hope this helped, it may irrelevant now if newer, faster ways have come out without using libraries and frameworks such as jQuery or W3.js.

UPDATE: This will throw an error saying that the local import has been blocked by CORS policy. Might need access to the deep web to be able to use this because of the properties of the deep web. (Meaning no practical use)

For O(1) random access, which can not be beaten.

in cellForRowAt indexPath:

 cell.prescriptionButton.addTarget(self, action: Selector("onClicked:"), for: .touchUpInside)

You reference a Linux distribution, so you need to install the readline development libraries

On Debian based platforms, like Ubuntu, you can run:

sudo apt-get install libreadline-dev 

and that should install the correct headers in the correct places,.

If you use a platform with yum, like SUSE, then the command should be:

yum install readline-devel

/usr/local/lib/node_modules is the correct directory for globally installed node modules.

/usr/local/share/npm/lib/node_modules makes no sense to me. One issue here is that you're confused because there are two directories called node_modules:

/usr/local/lib/node_modules
/usr/local/lib/node_modules/npm/node_modules

The latter seems to be node modules that came with Node, e.g., lodash, when the former is Node modules that I installed using npm.

DECLARE @TableName varchar(max)=NULL
SELECT @TableName=COALESCE(@TableName+',','')+t.TABLE_CATALOG+'.'+ t.TABLE_SCHEMA+'.'+o.Name
  FROM sysindexes AS i
  INNER JOIN sysobjects AS o ON i.id = o.id
  INNER JOIN INFORMATION_SCHEMA.TABLES T ON T.TABLE_NAME=o.name
 WHERE i.indid < 2
  AND OBJECTPROPERTY(o.id,'IsMSShipped') = 0
  AND i.rowcnt >350
  AND o.xtype !='TF'
 ORDER BY o.name ASC

 print @tablename

You can get list of tables which has rowcounts >350 . You can see at the solution list of table as row.

Other way to keep the caret position on the input:

$(document).ready(function() {
  $('.numbersOnly').on('input', function() {
    var position = this.selectionStart - 1;

    fixed = this.value.replace(/[^0-9\.]/g, '');  //remove all but number and .
    if(fixed.charAt(0) === '.')                  //can't start with .
      fixed = fixed.slice(1);

    var pos = fixed.indexOf(".") + 1;
    if(pos >= 0)
      fixed = fixed.substr(0,pos) + fixed.slice(pos).replace('.', '');  //avoid more than one .

    if (this.value !== fixed) {
      this.value = fixed;
      this.selectionStart = position;
      this.selectionEnd = position;
    }
  });
});

Advantages:

1. The user can use the arrow keys, Backspace, Delete, ...
2. Works when you want to paste numbers

Plunker: Demo working

With my now ageing Borland C++ Builder compiler enums can be 1,2 or 4 bytes, although it does have a flag you can flip to force it to use ints.

I guess it's compiler specific.

If you ever need to send GET request to an IP as well as a Domain (Other answers did not mention you can specify a port variable), you can make use of this function:

function getCode(host, port, path, queryString) {
    console.log("(" + host + ":" + port + path + ")" + "Running httpHelper.getCode()")

    // Construct url and query string
    const requestUrl = url.parse(url.format({
        protocol: 'http',
        hostname: host,
        pathname: path,
        port: port,
        query: queryString
    }));

    console.log("(" + host + path + ")" + "Sending GET request")
    // Send request
    console.log(url.format(requestUrl))
    http.get(url.format(requestUrl), (resp) => {
        let data = '';

        // A chunk of data has been received.
        resp.on('data', (chunk) => {
            console.log("GET chunk: " + chunk);
            data += chunk;
        });

        // The whole response has been received. Print out the result.
        resp.on('end', () => {
            console.log("GET end of response: " + data);
        });

    }).on("error", (err) => {
        console.log("GET Error: " + err);
    });
}

Don't miss requiring modules at the top of your file:

http = require("http");
url = require('url')

Also bare in mind that you may use https module for communicating over secured network. so these two lines would change:

https = require("https");
...
https.get(url.format(requestUrl), (resp) => { ......

Section 3 of RFC4122 provides the formal definition of UUID string representations. It's 36 characters (32 hex digits + 4 dashes).

Sounds like you need to figure out where the invalid 60-char IDs are coming from and decide 1) if you want to accept them, and 2) what the max length of those IDs might be based on whatever API is used to generate them.

Take a look at this example:

<!DOCTYPE HTML> 
<html>
<head>
</head>
<body> 

<?php
// define variables and set to empty values
$name = $email = $gender = $comment = $website = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
   $name = test_input($_POST["name"]);
   $email = test_input($_POST["email"]);
   $website = test_input($_POST["website"]);
   $comment = test_input($_POST["comment"]);
   $gender = test_input($_POST["gender"]);
}

function test_input($data) {
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
}
?>

I have seen many version of good answers here but it seems some folks are having cross browser issues so this is my fix.

I have used this successfully to detect direction in FF, IE and Chrome ... I haven't tested it in safari as I use windows typically.

$("html, body").bind({'mousewheel DOMMouseScroll onmousewheel touchmove scroll': 
    function(e) {
        if (e.target.id == 'el') return;
        e.preventDefault();
        e.stopPropagation();

        //Determine Direction
        if (e.originalEvent.wheelDelta && e.originalEvent.wheelDelta >= 0) {
            //Up
            alert("up");

        } else if (e.originalEvent.detail && e.originalEvent.detail <= 0) {
            //Up
            alert("up");

        } else {
            //Down
            alert("down");
        }
    }
});

Keep in mind I also use this to stop any scrolling so if you want scrolling to still occur you must remove the e.preventDefault(); e.stopPropagation();

A good trick is to use inner box-shadow, and let it do all the fading for you rather than applying it to the image.

you can use:

define("PATH_ROOT", dirname(__FILE__));

What database are you using? As far as I'm aware, there is no database agnostic method for doing this.

I have stumbled across this questions and answers after receiving the aforementioned error in IE11 when trying to upload files using XMLHttpRequest:

var reqObj = new XMLHttpRequest();

//event Handler
reqObj.upload.addEventListener("progress", uploadProgress, false);
reqObj.addEventListener("load", uploadComplete, false);
reqObj.addEventListener("error", uploadFailed, false);
reqObj.addEventListener("abort", uploadCanceled, false);

//open the object and set method of call (post), url to call, isAsynchronous(true)
reqObj.open("POST", $rootUrlService.rootUrl + "Controller/UploadFiles", true);

//set Content-Type at request header.for file upload it's value must be multipart/form-data
reqObj.setRequestHeader("Content-Type", "multipart/form-data");

//Set header properties : file name and project milestone id
reqObj.setRequestHeader('X-File-Name', name);

// send the file
// this is the line where the error occurs
reqObj.send(fileToUpload);

Removing the line reqObj.setRequestHeader("Content-Type", "multipart/form-data"); fixed the problem.

Note: this error is shown very differently in other browsers. I.e. Chrome shows something similar to a connection reset which is similar to what Fiddler reports (an empty response due to sudden connection close).

Also, this error appeared only when upload was done from a machine different from WebServer (no problems on localhost).

A "floating point number" is how computers usually represent numbers that are not integers -- basically, a number with a decimal point. In C++ you declare them with float instead of int. A floating point exception is an error that occurs when you try to do something impossible with a floating point number, such as divide by zero.

From the document of pandas,DataFrame structure can apply an operation (function) to itself .

DataFrame.apply(func, axis=0, broadcast=False, raw=False, reduce=None, args=(), **kwds)

Applies function along input axis of DataFrame. Objects passed to functions are Series objects having index either the DataFrame’s index (axis=0) or the columns (axis=1). Return type depends on whether passed function aggregates, or the reduce argument if the DataFrame is empty.

You can apply a custom function to operate the DataFrame .

Another way that works for me is,

<command> |& tee  <outputFile>

as shown in gnu bash manual

Example:

ls |& tee files.txt

If ‘|&’ is used, command1’s standard error, in addition to its standard output, is connected to command2’s standard input through the pipe; it is shorthand for 2>&1 |. This implicit redirection of the standard error to the standard output is performed after any redirections specified by the command.

Inside my project there is a .gradle folder which had cached the previous gradle version I was using (5.4.1) and gradle kept using that instead of my newly downloaded one (5.6.4).

Simply:

1. Close Android Studio
2. Delete the older gradle version folders from your project.
3. Restart Android Studio. Everything should be working correctly

In case this didn't work you can also try the following:

• Delete all versions in project .gradle folder so only the new one is redownloaded by AS when reopening the IDE.
• Check your project settings for gradle build version and make sure it is set to the latest one.
• Check that other modules aren't using older versions of the gradle build. You can search for this using project search (Ctrl+Shift+F) for "distributionUrl" and making sure that all modules have the latest version.
• Delete .gradle/caches under your root gradle folder, usually C://Users/{you}/.gradle
• try gradle build --stacktrace, --info, --scan or --debug in your AS terminal to get help and more info to debug your problem.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

1. @Component auto detects and configures the beans using classpath scanning whereas @Bean explicitly declares a single bean, rather than letting Spring do it automatically.
2. @Component does not decouple the declaration of the bean from the class definition where as @Bean decouples the declaration of the bean from the class definition.
3. @Component is a class level annotation whereas @Bean is a method level annotation and name of the method serves as the bean name.
4. @Component need not to be used with the @Configuration annotation where as @Bean annotation has to be used within the class which is annotated with @Configuration.
5. We cannot create a bean of a class using @Component, if the class is outside spring container whereas we can create a bean of a class using @Bean even if the class is present outside the spring container.
6. @Component has different specializations like @Controller, @Repository and @Service whereas @Bean has no specializations.

Darin's answer works great. It creates a 302 redirect. Here's the code modified so that it creates a permanent 301 redirect:

<%@ Page Language="C#" %>
<script runat="server">
  protected override void OnLoad(EventArgs e)
  {
      Response.RedirectPermanent("new.aspx");
      base.OnLoad(e);
  }
</script>

The answers only cover DOM / SAX and a copy paste implementation of a JAXB example.

However, one big area of when you are using XML is missing. In many projects / programs there is a need to store / retrieve some basic data structures. Your program has already a classes for your nice and shiny business objects / data structures, you just want a comfortable way to convert this data to a XML structure so you can do more magic on it (store, load, send, manipulate with XSLT).

This is where XStream shines. You simply annotate the classes holding your data, or if you do not want to change those classes, you configure a XStream instance for marshalling (objects -> xml) or unmarshalling (xml -> objects).

Internally XStream uses reflection, the readObject and readResolve methods of standard Java object serialization.

You get a good and speedy tutorial here:

To give a short overview of how it works, I also provide some sample code which marshalls and unmarshalls a data structure. The marshalling / unmarshalling happens all in the main method, the rest is just code to generate some test objects and populate some data to them. It is super simple to configure the xStream instance and marshalling / unmarshalling is done with one line of code each.

import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.List;

import com.thoughtworks.xstream.XStream;

public class XStreamIsGreat {

  public static void main(String[] args) {
    XStream xStream = new XStream();
    xStream.alias("good", Good.class);
    xStream.alias("pRoDuCeR", Producer.class);
    xStream.alias("customer", Customer.class);

    Producer a = new Producer("Apple");
    Producer s = new Producer("Samsung");
    Customer c = new Customer("Someone").add(new Good("S4", 10, new BigDecimal(600), s))
        .add(new Good("S4 mini", 5, new BigDecimal(450), s)).add(new Good("I5S", 3, new BigDecimal(875), a));
    String xml = xStream.toXML(c); // objects -> xml
    System.out.println("Marshalled:\n" + xml);
    Customer unmarshalledCustomer = (Customer)xStream.fromXML(xml); // xml -> objects
  }

  static class Good {
    Producer producer;

    String name;

    int quantity;

    BigDecimal price;

    Good(String name, int quantity, BigDecimal price, Producer p) {
      this.producer = p;
      this.name = name;
      this.quantity = quantity;
      this.price = price;
    }

  }

  static class Producer {
    String name;

    public Producer(String name) {
      this.name = name;
    }
  }

  static class Customer {
    String name;

    public Customer(String name) {
      this.name = name;
    }

    List<Good> stock = new ArrayList<Good>();

    Customer add(Good g) {
      stock.add(g);
      return this;
    }
  }
}

I think you can simple call like this, this will give you result value.

this.$route.query.page

Look image $route is object in Vue Instance and you can access with this keyword and next you can select object properties like above one :

Have a look Vue-router document for selecting queries value :

Vue Router Object

You can also try the find command. If you only want files in the current directory:

find . -d 1 -prune -ls

Run a command on each of them?

find . -d 1 -prune -exec echo {} \;

Count lines, but only in files?

find . -d 1 -prune -type f -exec wc -l {} \;

A few of the more serious problems:

• document.write (henceforth DW) does not work in XHTML

• DW does not directly modify the DOM, preventing further manipulation (trying to find evidence of this, but it's at best situational)

• DW executed after the page has finished loading will overwrite the page, or write a new page, or not work

• DW executes where encountered: it cannot inject at a given node point

• DW is effectively writing serialised text which is not the way the DOM works conceptually, and is an easy way to create bugs (.innerHTML has the same problem)

Far better to use the safe and DOM friendly DOM manipulation methods

A bit late but I thought I'd share in case it helps anyone: what is most likely the problem is simply that your Debug Console (the command line window that opens when run your project if it is a Windows Console Application) is still open from the last time you ran the code. Just close that window, then rebuild and run: Ctrl + B and F5, respectively.

First try to see what's wrong with the pod:

kubectl logs -p <your_pod>

In my case it was a problem with the YAML file.

So, I needed to correct the configuration file and replace it:

kubectl replace --force -f <yml_file_describing_pod>

Try

$ git diff --stat --color master..branchName

This will give you more info about each change, while still using the same number of lines.

You can also flip the branches to get an even clearer picture of the difference if you were to merge the other way:

$ git diff --stat --color branchName..master

You may try this:

Page::where('id', $id)->update(array('image' => 'asdasd'));

There are other ways too but no need to use Page::find($id); in this case. But if you use find() then you may try it like this:

$page = Page::find($id);

// Make sure you've got the Page model
if($page) {
    $page->image = 'imagepath';
    $page->save();
}

Also you may use:

$page = Page::findOrFail($id);

So, it'll throw an exception if the model with that id was not found.

To select the sibling, you'd need something like:

$(this).next();

So, Shog9's comment is not correct. First of all, you'd need to name the variable "clicked" outside of the div click function, otherwise, it is lost after the click occurs.

var clicked;

$("div a").click(function(){
   clicked = $(this).next();
   // Do what you need to do to the newly defined click here
});

// But you can also access the "clicked" element here

The accepted answer didn't work for me on JQuery 2.x .is(":hover") returns false on every call.

I ended up with a pretty simple solution that works:

function isHovered(selector) {

    return $(selector+":hover").length > 0

}

pandas.isnull() (also pd.isna(), in newer versions) checks for missing values in both numeric and string/object arrays. From the documentation, it checks for:

NaN in numeric arrays, None/NaN in object arrays

Quick example:

import pandas as pd
import numpy as np
s = pd.Series(['apple', np.nan, 'banana'])
pd.isnull(s)
Out[9]: 
0    False
1     True
2    False
dtype: bool

The idea of using numpy.nan to represent missing values is something that pandas introduced, which is why pandas has the tools to deal with it.

Datetimes too (if you use pd.NaT you won't need to specify the dtype)

In [24]: s = Series([Timestamp('20130101'),np.nan,Timestamp('20130102 9:30')],dtype='M8[ns]')

In [25]: s
Out[25]: 
0   2013-01-01 00:00:00
1                   NaT
2   2013-01-02 09:30:00
dtype: datetime64[ns]``

In [26]: pd.isnull(s)
Out[26]: 
0    False
1     True
2    False
dtype: bool

I found the most supported way to do this, without worrying about a third party library, was by using getTimezoneOffset to calculate the appropriate timestamp, or update the time then use the normal methods to get the necessary date and time.

var mydate = new Date();
mydate.setFullYear(2013);
mydate.setMonth(02);
mydate.setDate(28);
mydate.setHours(7);
mydate.setMinutes(00);

// ET timezone offset in hours.
var timezone = -5;
// Timezone offset in minutes + the desired offset in minutes, converted to ms.
// This offset should be the same for ALL date calculations, so you should only need to calculate it once.
var offset = (mydate.getTimezoneOffset() + (timezone * 60)) * 60 * 1000;

// Use the timestamp and offset as necessary to calculate min/sec etc, i.e. for countdowns.
var timestamp = mydate.getTime() + offset,
    seconds = Math.floor(timestamp / 1000) % 60,
    minutes = Math.floor(timestamp / 1000 / 60) % 60,
    hours   = Math.floor(timestamp / 1000 / 60 / 60);

// Or update the timestamp to reflect the timezone offset.
mydate.setTime(mydate.getTime() + offset);
// Then Output dates and times using the normal methods.
var date = mydate.getDate(),
    hour = mydate.getHours();

EDIT

I was previously using UTC methods when performing the date transformations, which was incorrect. With adding the offset to the time, using the local get functions will return the desired results.

Java is only pass-by-value. (or better - pass-reference-by-value)

So the passed argument and the argument within the method are two different handlers pointing to the same object (value).

Therefore if you change the state of the object, it is reflected to every other variable that's referencing it. But if you re-assign a new object (value) to the argument, then other variables pointing to this object (value) do not get re-assigned.

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):

• length
• precision
• scale
• nullable
• unique

i.e. the column DDL will consist of: name + columndefinition and nothing else.

Rationale follows.

1. Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.

2. Other annotation purely logical - properties used in-memory in java to control JPA processing.

3. That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.

In your example, length and nullable properties are overridden and redundant.

So, when specifying columnDefinition, what other properties of @Column are made redundant?

1. In JPA Spec & javadoc:

   • columnDefinition definition: The SQL fragment that is used when generating the DDL for the column.

   • columnDefinition default: Generated SQL to create a column of the inferred type.

   • The following examples are provided:

     @Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
     @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
     

   • And, err..., that's it really. :-$ ?!

   Does columnDefinition override other properties provided in the same annotation?

   The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.

2. The following can be safely implied from examples provided in the JPA spec

   • name & table can be used in conjunction with columnDefinition, neither are overridden
   • nullable is overridden/made redundant by columnDefinition

3. The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):

   • length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the type
   • insertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.

4. That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.

Test My Answer For columns "A" & "B", respectively:

  @Column(name="...", table="...", insertable=true, updateable=false,
          columndefinition="NUMBER(5,2) NOT NULL UNIQUE"

  @Column(name="...", table="...", insertable=false, updateable=true,
          columndefinition="NVARCHAR2(100) NULL"

• confirm generated table has correct type/nullability/uniqueness
• optionally, do JPA insert & update: former should include column A, latter column B

Not sure if this solution has been mentioned anywhere yet but one way to do is is pandas.Index.difference.

>>> df = pd.DataFrame(columns=['A','B','C','D'])
>>> df
Empty DataFrame
Columns: [A, B, C, D]
Index: []
>>> to_remove = ['A','C']
>>> df = df[df.columns.difference(to_remove)]
>>> df
Empty DataFrame
Columns: [B, D]
Index: []

I use this alert

<div class="alert alert-error hidden" id="successfulSave">
  <span>
    <p>Success! Result Saved.</p>
  </span>
</div>

repeatedly on a page each time a user updates a result successfully:

$('#successfulSave').removeClass('hidden');

to re-hide it, I call

$('#successfulSave').addClass('hidden');

I use something similar to what posit labs does. Save the console in a closure and you have it all in one portable function.

var GlobalDebug = (function () {
    var savedConsole = console;
    return function(debugOn,suppressAll){
        var suppress = suppressAll || false;
        if (debugOn === false) {
            console = {};
            console.log = function () { };
            if(suppress) {
                console.info = function () { };
                console.warn = function () { };
                console.error = function () { };
            } else {
                console.info = savedConsole.info;
                console.warn = savedConsole.warn;
                console.error = savedConsole.error;              
            }
        } else {
            console = savedConsole;
        }
    }
})();

Just do globalDebug(false) to toggle log messages off or globalDebug(false,true) to remove all console messages.

Try this,

HtmlElement head = _windowManager.ActiveBrowser.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = _windowManager.ActiveBrowser.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "window.onload = function() { document.forms[0].submit(); }";
head.AppendChild(scriptEl);
strAdditionalHeader = "";
_windowManager.ActiveBrowser.Document.InvokeScript("webBrowserControl");

Also you are tying up a threadpool thread for the lifetime of the background worker, which may be of concern as there are only a finite number of them. I would say that if you are only ever creating the thread once for your app (and not using any of the features of background worker) then use a thread, rather than a backgroundworker/threadpool thread.

You can use the V3 API to get a raw file like this (you'll need an OAuth token):

curl -H 'Authorization: token INSERTACCESSTOKENHERE' -H 'Accept: application/vnd.github.v3.raw' -O -L https://api.github.com/repos/*owner*/*repo*/contents/*path*

All of this has to go on one line. The -O option saves the file in the current directory. You can use -o filename to specify a different filename.

To get the OAuth token follow the instructions here: https://help.github.com/articles/creating-an-access-token-for-command-line-use

I've written this up as a gist as well: https://gist.github.com/madrobby/9476733

see if something show on the filter box in console ,it means something override your script clear the filter box and check again. i my case this is the issue.

Everyone else has posted "going backwards" answer, so I'll give the alternative: create a list of items you want to remove, then remove them at the end:

List<string> removals = new List<string>();
foreach (string s in listBox1.Items)
{
    MessageBox.Show(s);
    //do stuff with (s);
    removals.Add(s);
}

foreach (string s in removals)
{
    listBox1.Items.Remove(s);
}

Sometimes the "work backwards" method is better, sometimes the above is better - particularly if you're dealing with a type which has a RemoveAll(collection) method. Worth knowing both though.

The Catch is Capture all SQL run between two points in time. Like the way SQL Server also does.

There are situations where it is useful to capture the SQL that a particular user is running in the database. Usually you would simply enable session tracing for that user, but there are two potential problems with that approach.

1. The first is that many web based applications maintain a pool of persistent database connections which are shared amongst multiple users.
2. The second is that some applications connect, run some SQL and disconnect very quickly, making it tricky to enable session tracing at all (you could of course use a logon trigger to enable session tracing in this case).

A quick and dirty solution to the problem is to capture all SQL statements that are run between two points in time.

The following procedure will create two tables, each containing a snapshot of the database at a particular point. The tables will then be queried to produce a list of all SQL run during that period.

If possible, you should do this on a quiet development system - otherwise you risk getting way too much data back.

1. Take the first snapshot Run the following sql to create the first snapshot:

   create table sql_exec_before as
   select executions,hash_value
   from v$sqlarea
   /
   

2. Get the user to perform their task within the application.

3. Take the second snapshot.

   create table sql_exec_after as
   select executions, hash_value
   from v$sqlarea
   /
   

4. Check the results Now that you have captured the SQL it is time to query the results.

This first query will list all query hashes that have been executed:

select  aft.hash_value
from sql_exec_after aft
left outer join sql_exec_before bef
  on aft.hash_value  =  bef.hash_value 
where aft.executions > bef.executions
   or bef.executions is null;
/

This one will display the hash and the SQL itself: set pages 999 lines 100 break on hash_value

select  hash_value, sql_text
from    v$sqltext
where   hash_value in (
    select  aft.hash_value
    from sql_exec_after aft
    left outer join sql_exec_before bef
      on aft.hash_value  =  bef.hash_value
    where aft.executions > bef.executions
       or bef.executions is null;
)
order by
    hash_value, piece
/

5. Tidy up Don't forget to remove the snapshot tables once you've finished:

drop table sql_exec_before
/

drop table sql_exec_after
/

In case you don't want (or have) a running container, you can call your script directly with the run command.

Remove the iterative tty -i -t arguments and use this:

    $ docker run ubuntu:bionic /bin/bash /path/to/script.sh

This will (didn't test) also work for other scripts:

    $ docker run ubuntu:bionic /usr/bin/python /path/to/script.py

Unfortunately although the Array.join approach mentioned here is terse, it is about 10X slower than a string-concatenation-based implementation. It performs especially badly on large strings. See below for full performance details.

On Firefox, Chrome, Node.js MacOS, Node.js Ubuntu, and Safari, the fastest implementation I tested was:

function repeatChar(count, ch) {
    if (count == 0) {
        return "";
    }
    var count2 = count / 2;
    var result = ch;

    // double the input until it is long enough.
    while (result.length <= count2) {
        result += result;
    }
    // use substring to hit the precise length target without
    // using extra memory
    return result + result.substring(0, count - result.length);
};

This is verbose, so if you want a terse implementation you could go with the naive approach; it still performs betweeb 2X to 10X better than the Array.join approach, and is also faster than the doubling implementation for small inputs. Code:

// naive approach: simply add the letters one by one
function repeatChar(count, ch) {
    var txt = "";
    for (var i = 0; i < count; i++) {
        txt += ch;
    }
    return txt;
}

blazeroni already made it pretty clear, I just want to add few points.

• <merge> is used for optimizing layouts.It is used for reducing unnecessary nesting.
• when a layout containing <merge> tag is added into another layout,the <merge> node is removed and its child view is added directly to the new parent.

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Answer to the question:

var Db = require('mongodb').Db,
    MongoClient = require('mongodb').MongoClient,
    Server = require('mongodb').Server,
    ReplSetServers = require('mongodb').ReplSetServers,
    ObjectID = require('mongodb').ObjectID,
    Binary = require('mongodb').Binary,
    GridStore = require('mongodb').GridStore,
    Code = require('mongodb').Code,
    BSON = require('mongodb').pure().BSON,
    assert = require('assert');

var db = new Db('integration_tests', new Server("127.0.0.1", 27017,
 {auto_reconnect: false, poolSize: 4}), {w:0, native_parser: false});

// Establish connection to db
db.open(function(err, db) {
  assert.equal(null, err);

  // Add a user to the database
  db.addUser('user', 'name', function(err, result) {
    assert.equal(null, err);

    // Authenticate
    db.authenticate('user', 'name', function(err, result) {
      assert.equal(true, result);

      db.close();
    });
  });
});

If the array is sorted in ascending or descending order then you can find it with complexity O(1). For an array of ascending order the first element is the smallest element, you can get it by arr[0] (0 based indexing). If the array is sorted in descending order then the last element is the smallest element,you can get it by arr[sizeOfArray-1].

If the array is not sorted then you have to iterate over the array to get the smallest element.In this case time complexity is O(n), here n is the size of array.

int arr[] = {5,7,9,0,-3,2,3,4,56,-7};
int smallest_element=arr[0] //let, first element is the smallest one

for(int i =1;i<sizeOfArray;i++)  
{
    if(arr[i]<smallest_element)
    {
     smallest_element=arr[i];
    }
}

You can calculate it in input section (when you have to find smallest element from a given array)

int smallest_element;
int arr[100],n;
cin>>n;
for(int i = 0;i<n;i++)
{
cin>>arr[i];
if(i==0)
{
    smallest_element=arr[i]; //smallest_element=arr[0];
}
else if(arr[i]<smallest_element)
{
smallest_element = arr[i];
}
}

Also you can get smallest element by built in function

#inclue<algorithm>
int smallest_element = *min_element(arr,arr+n); //here n is the size of array

You can get smallest element of any range by using this function such as,

int arr[] = {3,2,1,-1,-2,-3};
cout<<*min_element(arr,arr+3); //this will print 1,smallest element of first three element
cout<<*min_element(arr+2,arr+5); // -2, smallest element between third and fifth element (inclusive) 

I have used asterisk (*), before min_element() function. Because it returns pointer of smallest element. All codes are in c++. You can find the maximum element in opposite way.

You can, and should, just write a for loop. Simple, obvious code is the Go way.

for i := 1; i <= 10; i++ {
    fmt.Println(i)
}

To call any method of an object instantiated from a class (with statement new), you need to "point" to it. From the outside you just use the resource created by the new statement. Inside any object PHP created by new, saves the same resource into the $this variable. So, inside a class you MUST point to the method by $this. In your class, to call smallTest from inside the class, you must tell PHP which of all the objects created by the new statement you want to execute, just write:

$this->smallTest();

If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what's visible at a certain time.

Here's a simple pagination example: http://jsfiddle.net/2ZzZB/56/

That example was on the list of fiddles on the angular.js github wiki, which should be helpful: https://github.com/angular/angular.js/wiki/JsFiddle-Examples

EDIT: http://jsfiddle.net/2ZzZB/16/ to http://jsfiddle.net/2ZzZB/56/ (won't show "1/4.5" if there is 45 results)

My case was to print horizontal (landscape) summary section - so:

}).then((canvas) => {
  const img = canvas.toDataURL('image/jpg');
  new jsPDF({
        orientation: 'l', // landscape
        unit: 'pt', // points, pixels won't work properly
        format: [canvas.width, canvas.height] // set needed dimensions for any element
  });
  pdf.addImage(img, 'JPEG', 0, 0, canvas.width, canvas.height);
  pdf.save('your-filename.pdf');
});

Use preg_replace() and instead of [ \t\n\r] use \s:

$output = preg_replace('!\s+!', ' ', $input);

From Regular Expression Basic Syntax Reference:

\d, \w and \s

Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.

According to Martin Fowler a POJO is an object which encapsulates Business Logic while a Bean (except for the definition already stated in other answers) is little more than a container for holding data and the operations available on the object merely set and get data.

The term was coined while Rebecca Parsons, Josh MacKenzie and I were preparing for a talk at a conference in September 2000. In the talk we were pointing out the many benefits of encoding business logic into regular java objects rather than using Entity Beans. We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it's caught on very nicely.

I had

runtime('mysql:mysql-connector-java')

Changed to

compile('mysql:mysql-connector-java')

Fixed my problem

You use it like this:

SELECT  age, name
FROM    users
UNION
SELECT  25 AS age, 'Betty' AS name

Use UNION ALL to allow duplicates: if there is a 25-years old Betty among your users, the second query will not select her again with mere UNION.

There are quite few solutions to tackle this issue. First you can go for a plugin if you want:

• WordPress Quickie: Custom Query String Plugin

Or code manually, check out this post:

• Passing Query String Parameters in WordPress URL

Also check out:

• add_query_arg

You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.

outfile.write(plaintext.encode('utf-8'))

is possibly what you want. Also this works for both python 2.x and 3.x.

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

This can also be a issue when you enter wrong password for your sign key.

I've just had the same problem.

You only get the text twice in your result if you include a match group (in brackets) and the 'g' (global) modifier. The first item always is the first result, normally OK when using match(reg) on a short string, however when using a construct like:

while ((result = reg.exec(string)) !== null){
    console.log(result);
}

the results are a little different.

Try the following code:

var regEx = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
var result = sample_string.match(regEx);
console.log(JSON.stringify(result));
// ["1 cat","2 fish"]

var reg = new RegExp('[0-9]+ (cat|fish)','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null) {
    console.dir(JSON.stringify(result))
};
// '["1 cat","cat"]'
// '["2 fish","fish"]'

var reg = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null){
    console.dir(JSON.stringify(result))
};
// '["1 cat","1 cat","cat"]'
// '["2 fish","2 fish","fish"]'

The best answer is currently a comment which I can't upvote, so credit to @Mic.

You can set max connections using:

set global max_connections = '1 < your number > 100000';

This will set your number of mysql connection unti (Requires SUPER privileges).

I want to add some clarification to this thread:

Update-Database -TargetMigration:"name_of_migration"

What you are doing above is saying that you want to rollback all migrations UNTIL you're left with the migration specified. Thus, if you use GET-MIGRATIONS and you find that you have A, B, C, D, and E, then using this command will rollback E and D to get you to C:

Update-Database -TargetMigration:"C"

Also, unless anyone can comment to the contrary, I noticed that you can use an ordinal value and the short -Target switch (thus, -Target is the same as -TargetMigration). If you want to rollback all migrations and start over, you can use:

Update-Database -Target:0

0, above, would rollback even the FIRST migration (this is a destructive command--be sure you know what you're doing before you use it!)--something you cannot do if you use the syntax above that requires the name of the target migration (the name of the 0th migration doesn't exist before a migration is applied!). So in that case, you have to use the 0 (ordinal) value. Likewise, if you have applied migrations A, B, C, D, and E (in that order), then the ordinal 1 should refer to A, ordinal 2 should refer to B, and so on. So to rollback to B you could use either:

Update-Database -TargetMigration:"B"

or

Update-Database -TargetMigration:2

Edit October 2019:

According to this related answer on a similar question, correct command is -Target for EF Core 1.1 while it is -Migration for EF Core 2.0.

You can use skip and take functions as below:

$products = $art->products->skip($offset*$limit)->take($limit)->get();

// skip should be passed param as integer value to skip the records and starting index

// take gets an integer value to get the no. of records after starting index defined by skip

EDIT

Sorry. I was misunderstood with your question. If you want something like pagination the forPage method will work for you. forPage method works for collections.

REf : https://laravel.com/docs/5.1/collections#method-forpage

e.g

$products = $art->products->forPage($page,$limit);

I don't have a windows box handy to try this but I think you can use a DataView and do something like so:

DataView view = new DataView(ds.Tables["MyTable"]);
view.RowFilter = "MyValue = 42"; // MyValue here is a column name

// Delete these rows.
foreach (DataRowView row in view)
{
  row.Delete();
}

I haven't tested this, though. You might give it a try.

BSTR to std::wstring:

// given BSTR bs
assert(bs != nullptr);
std::wstring ws(bs, SysStringLen(bs));

 
std::wstring to BSTR:

// given std::wstring ws
assert(!ws.empty());
BSTR bs = SysAllocStringLen(ws.data(), ws.size());

Doc refs:

1. std::basic_string<typename CharT>::basic_string(const CharT*, size_type)

Precision of a number is the number of digits.

Scale of a number is the number of digits after the decimal point.

What is generally implied when setting precision and scale on field definition is that they represent maximum values.

Example, a decimal field defined with precision=5 and scale=2 would allow the following values:

• 123.45 (p=5,s=2)
• 12.34 (p=4,s=2)
• 12345 (p=5,s=0)
• 123.4 (p=4,s=1)
• 0 (p=0,s=0)

The following values are not allowed or would cause a data loss:

• 12.345 (p=5,s=3) => could be truncated into 12.35 (p=4,s=2)
• 1234.56 (p=6,s=2) => could be truncated into 1234.6 (p=5,s=1)
• 123.456 (p=6,s=3) => could be truncated into 123.46 (p=5,s=2)
• 123450 (p=6,s=0) => out of range

Note that the range is generally defined by the precision: |value| < 10^p ...

You need some 32-bit binaries, and you have a 64-bit OS version (apparently). Try:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

That worked for me on Ubuntu 14.10.

UPDATE 2017-12-16: The details will vary by Linux distro and version. So for example, this answer covers newer Ubuntu versions.

This is so simple. Try:

date_time = str(datetime.datetime.now())
date = date_time.split()[0]
time = date_time.split()[1]

I thought this could be solved by telling git that the file exists, rather than committing all of the contents of it to the staging area, and then call git stash. Araqnid describes how to do the former.

git add --intent-to-add path/to/untracked-file

or

git update-index --add --cacheinfo 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 path/to/untracked-file

However, the latter doesn't work:

$ git stash
b.rb: not added yet
fatal: git-write-tree: error building trees
Cannot save the current index state

Let's break down the full URL that a client would type into their address bar to reach your servlet:

http://www.example.com:80/awesome-application/path/to/servlet/path/info?a=1&b=2#boo

The parts are:

1. scheme: http
2. hostname: www.example.com
3. port: 80
4. context path: awesome-application
5. servlet path: path/to/servlet
6. path info: path/info
7. query: a=1&b=2
8. fragment: boo

The request URI (returned by getRequestURI) corresponds to parts 4, 5 and 6.

(incidentally, even though you're not asking for this, the method getRequestURL would give you parts 1, 2, 3, 4, 5 and 6).

Now:

• part 4 (the context path) is used to select your particular application out of many other applications that may be running in the server
• part 5 (the servlet path) is used to select a particular servlet out of many other servlets that may be bundled in your application's WAR
• part 6 (the path info) is interpreted by your servlet's logic (e.g. it may point to some resource controlled by your servlet).
• part 7 (the query) is also made available to your servlet using getQueryString
• part 8 (the fragment) is not even sent to the server and is relevant and known only to the client

The following always holds (except for URL encoding differences):

requestURI = contextPath + servletPath + pathInfo

The following example from the Servlet 3.0 specification is very helpful:

Note: image follows, I don't have the time to recreate in HTML:

I tried different approaches but every one had some weak points (i.e. with cut and paste or browser compatibility). This is the solution I'm using right now:

function multilineTextBoxKeyUp(textBox, e, maxLength) {
    if (!checkSpecialKeys(e)) {
        var length = parseInt(maxLength);
        if (textBox.value.length > length) {
            textBox.value = textBox.value.substring(0, maxLength);
        }
    }
}

function multilineTextBoxKeyDown(textBox, e, maxLength) {
    var selectedText = document.selection.createRange().text;
    if (!checkSpecialKeys(e) && !e.ctrlKey && selectedText.length == 0) {
        var length = parseInt(maxLength);
        if (textBox.value.length > length - 1) {
            if (e.preventDefault) {
                e.preventDefault();
            }
            else {
                e.returnValue = false;
            }
        }
    }
}

function checkSpecialKeys(e) {
    if (e.keyCode != 8 && e.keyCode != 9 && e.keyCode != 33 && e.keyCode != 34 && e.keyCode != 35 && e.keyCode != 36 && e.keyCode != 37 && e.keyCode != 38 && e.keyCode != 39 && e.keyCode != 40) {
        return false;
    } else {
        return true;
    }
}

In this case, I'm calling multilineTextBoxKeyUp on key up and multilineTextBoxKeyDown on key down:

myTextBox.Attributes.Add("onkeyDown", "multilineTextBoxKeyDown(this, event, '" + maxLength + "');");
myTextBox.Attributes.Add("onkeyUp", "multilineTextBoxKeyUp(this, event, '" + maxLength + "');");

@media (min-width: @screen-sm-min) {
    div.equal-height-sm {
        display: table;


        > div[class^='col-'] {
            display: table-cell;
            float: none;
            vertical-align: top;
        }
    }
}

<div class="equal-height-sm">
    <div class="col-xs-12 col-sm-7">Test<br/>Test<br/>Test</div>
    <div class="col-xs-12 col-sm-5">Test</div>

Adapted from several answers here. The flexbox-based answers are the right way once IE8 and 9 are dead, and once Android 2.x is dead, but that is not true in 2015, and likely won't be in 2016. IE8 and 9 still make up 4-6% of usage depending on how you measure, and for many corporate users it's much worse. http://caniuse.com/#feat=flexbox

The display: table, display: table-cell trick is more backwards-compatible - and one great thing is the only serious compatibility issue is a Safari issue where it forces box-sizing: border-box, something already applied to your Bootstrap tags. http://caniuse.com/#feat=css-table

You can obviously add more classes that do similar things, like .equal-height-md. I tied these to divs for the small performance benefit in my constrained usage, but you could remove the tag to make it more generalized like the rest of Bootstrap.

Note that the jsfiddle here uses CSS, and so, things Less would otherwise provide are hard-coded in the linked example. For example @screen-sm-min has been replaced with what Less would insert - 768px.

I did this as an experiment to reset the value to 0 as I want my first identity column to be 0 and it's working.

There is no separate 64-bit version of Chromedriver. The version available at https://sites.google.com/a/chromium.org/chromedriver/downloads works on both 32 and 64-bit Windows, against either 32-or 64-bit Chrome.

This was confirmed in the Chromedriver issue tracker: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1797#c1

Yes, Chromedriver works on 64-bit Windows and against 64-bit Chrome successfully.

I came here while searching for the answer to if it works on 64-bit Chrome following the announcement that from version 58 Chrome will default to 64-bit on Windows provided certain conditions are met:
https://chromereleases.googleblog.com/2017/05/stable-channel-update-for-desktop.html

In order to improve stability, performance, and security, users who are currently on 32-bit version of Chrome, and 64-bit Windows with 4GB or more of memory and auto-update enabled will be automatically migrated to 64-bit Chrome during this update. 32-bit Chrome will still be available via the Chrome download page.

Using JDK 1.6 or later

It has been pointed out by Justin in the comments below that keytool alone is capable of doing this using the following command (although only in JDK 1.6 and later):

keytool -importkeystore -srckeystore mypfxfile.pfx -srcstoretype pkcs12 
-destkeystore clientcert.jks -deststoretype JKS

Using JDK 1.5 or below

OpenSSL can do it all. This answer on JGuru is the best method that I've found so far.

Firstly make sure that you have OpenSSL installed. Many operating systems already have it installed as I found with Mac OS X.

The following two commands convert the pfx file to a format that can be opened as a Java PKCS12 key store:

openssl pkcs12 -in mypfxfile.pfx -out mypemfile.pem
openssl pkcs12 -export -in mypemfile.pem -out mykeystore.p12 -name "MyCert"

NOTE that the name provided in the second command is the alias of your key in the new key store.

You can verify the contents of the key store using the Java keytool utility with the following command:

keytool -v -list -keystore mykeystore.p12 -storetype pkcs12

Finally if you need to you can convert this to a JKS key store by importing the key store created above into a new key store:

keytool -importkeystore -srckeystore mykeystore.p12 -destkeystore clientcert.jks -srcstoretype pkcs12 -deststoretype JKS

Rsync daemon by default uses nobody/nogroup for all modules if it is running under root user. So you either need to define params uid and gid to the user you want, or set them to root/root.

I wanted to do something similar. But getting the text value from edit text and comparing it like (str=="") wasn't working for me. So better option was:

EditText eText = (EditText) findViewById(R.id.etext);

if (etext.getText().length() == 0)
{//do what you want }

Worked like a charm.

The related_name argument is also useful if you have more complex related class names. For example, if you have a foreign key relationship:

class UserMapDataFrame(models.Model):
    user = models.ForeignKey(User) 

In order to access UserMapDataFrame objects from the related User, the default call would be User.usermapdataframe_set.all(), which it is quite difficult to read.

Using the related_name allows you to specify a simpler or more legible name to get the reverse relation. In this case, if you specify user = models.ForeignKey(User, related_name='map_data'), the call would then be User.map_data.all().

This exception may also occur if you are using Sockets on one side and SSLSockets on the other. Consistency is important.

If your using Office 2016 or later, or Office 365, there is a new function that acts similarly to a CASE function called IFS. Here's the description of the function from Microsoft's documentation:

The IFS function checks whether one or more conditions are met, and returns a value that corresponds to the first TRUE condition. IFS can take the place of multiple nested IF statements, and is much easier to read with multiple conditions.

An example of usage follows:

=IFS(A2>89,"A",A2>79,"B",A2>69,"C",A2>59,"D",TRUE,"F")

You can even specify a default result:

To specify a default result, enter TRUE for your final logical_test argument. If none of the other conditions are met, the corresponding value will be returned.

The default result feature is included in the example shown above.

You can read more about it on Microsoft's Support Documentation

There is no way to know unless the particular company reveals the info. The best you can do is find a few companies that are sharing and then extrapolate based on app ranking (which is available publicly). The best you'll get is a ball park estimate.

You can read the innerHTML attribute to get the source of the content of the element or outerHTML for the source with the current element.

Python:

element.get_attribute('innerHTML')

Java:

elem.getAttribute("innerHTML");

C#:

element.GetAttribute("innerHTML");

Ruby:

element.attribute("innerHTML")

JavaScript:

element.getAttribute('innerHTML');

PHP:

$element->getAttribute('innerHTML');

        file_name = zip_names.pop()
        extracted_file = zipfile.open(file_name)
        return extracted_file
    return [zipfile.open(file_name) for file_name in zip_names]

If you need to get the user from within the controller, use the User property of Controller. If you need it from the view, I would populate what you specifically need in the ViewData, or you could just call User as I think it's a property of ViewPage.

        return {

                taskUpload: $resource(taskModelUrl, {
                    id: '@id'
                }, {
                    save: {
                        method: "POST",
                        isArray: false,
                        headers: {"Content-Type": undefined},
                        transformRequest: angular.identity
                    }
                })
            }
        };
    }
]);

And then use it in a module:

task.module.js

$ngModelTask.controller("taskController", [
    "$scope",
    "$taskService",
    function (
        $scope,
        $taskService,
    ) {
    $scope.saveTask = function (name, file) {
        var newTask,
            payload = new FormData();
        payload.append("name", name);
        payload.append("file", file);
        newTask = $taskService.rest.taskUpload.save(payload);
        // check if exists
    }
}

The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.

If we look at the widely proposed regex for this question:

.*[^a]$

We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:

.*[^a][^b][^c]$

won't do. It won't accept ac, for example.

There is an easy solution for this problem though. We can simply say:

.{,2}$|.*[^a][^b][^c]$

or more generalized version:

.{,n-1}$|.*[^firstchar][^secondchar]$ where n is length of the string you want forbid (for abc it's 3), and firstchar, secondchar, ... are first, second ... nth characters of your string (for abc it would be a, then b, then c).

This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.

Here's an example of find that will delete all files that are not .jpg:

find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete

I am doing something similar but in C++. What you need to do is read the lines in one at a time and parse them (go over the words one by one). I have an outter loop that goes over all the lines and inside that is another loop that goes over all the words. Once the word you need is found, just exit the loop and return a counter or whatever you want.

This is my code. It basically parses out all the words and adds them to the "index". The line that word was in is then added to a vector and used to reference the line (contains the name of the file, the entire line and the line number) from the indexed words.

ifstream txtFile;
txtFile.open(path, ifstream::in);
char line[200];
//if path is valid AND is not already in the list then add it
if(txtFile.is_open() && (find(textFilePaths.begin(), textFilePaths.end(), path) == textFilePaths.end())) //the path is valid
{
    //Add the path to the list of file paths
    textFilePaths.push_back(path);
    int lineNumber = 1;
    while(!txtFile.eof())
    {
        txtFile.getline(line, 200);
        Line * ln = new Line(line, path, lineNumber);
        lineNumber++;
        myList.push_back(ln);
        vector<string> words = lineParser(ln);
        for(unsigned int i = 0; i < words.size(); i++)
        {
            index->addWord(words[i], ln);
        }
    }
    result = true;
}

Requests natively supports basic auth only with user-pass params, not with tokens.

You could, if you wanted, add the following class to have requests support token based basic authentication:

import requests
from base64 import b64encode

class BasicAuthToken(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        authstr = 'Basic ' + b64encode(('token:' + self.token).encode('utf-8')).decode('utf-8')
        r.headers['Authorization'] = authstr
        return r

Then, to use it run the following request :

r = requests.get(url, auth=BasicAuthToken(api_token))

An alternative would be to formulate a custom header instead, just as was suggested by other users here.

c# code

int i = 0;
char c = '?';
i = (int)c;
Console.WriteLine(i); // prints 8593

int j = 0;
char d = '?';
j = (int)d;
Console.WriteLine(j); // prints 8595

Candidate keys - A minimal column combination required to uniquely identify a table row.
Compound keys - 2 or more columns.

• Multiple Candidate keys can exist in a table.
  • Primary KEY - Only one of the candidate keys that is chosen by us
  • Alternate keys - All other candidate keys
    • Both Primary Key & Alternate keys can be Compound keys

    // this will give all the forms on the page.

    $('form')

   // If you know the name of form then.

    $('form[name="myFormName"]')

  //  If you don't know know the name but the position (starts with 0)

    $('form:eq(1)')  // 2nd form will be fetched.

Try this:

CREATE FUNCTION dbo.FnDAYSADDNOWK(
          @addDate AS DATE, 
          @numDays AS INT
       ) RETURNS DATETIME AS

    BEGIN
    WHILE @numDays > 0 BEGIN
        SET @addDate = DATEADD(day, 1, @addDate)    
        IF DATENAME(DW, @addDate) <> 'sunday' BEGIN
            SET @numDays = @numDays - 1 
        END
    END

    RETURN CAST(@addDate AS DATETIME)
END

This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or ThreadPool function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.

You can do something like this:

function writeFile(i){
    var i = i || 0;
    var fileName = 'a_' + i + '.jpg';
    fs.exists(fileName, function (exists) {
        if(exists){
            writeFile(++i);
        } else {
            fs.writeFile(fileName);
        }
    });
}

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

Use:

byte[] data = Base64.encode(base64str);

Encoding converts to Base64

You would need to reference commons codec from your project in order for that code to work.

For java8:

import java.util.Base64

Using a nested .each() means that your inner loop is doing one td at a time, so you can't set the productId and product and quantity all in the inner loop.

Also using function(key, val) and then val[key].innerHTML isn't right: the .each() method passes the index (an integer) and the actual element, so you'd use function(i, element) and then element.innerHTML. Though jQuery also sets this to the element, so you can just say this.innerHTML.

Anyway, here's a way to get it to work:

    table.find('tr').each(function (i, el) {
        var $tds = $(this).find('td'),
            productId = $tds.eq(0).text(),
            product = $tds.eq(1).text(),
            Quantity = $tds.eq(2).text();
        // do something with productId, product, Quantity
    });

Demo: http://jsfiddle.net/bqX7Q/

Try this:

jQuery('body').after('<a id="Download" target="_blank">Click Here</a>');

var canvas = document.getElementById('canvasID');
var ctx = canvas.getContext('2d');

document.getElementById('Download').addEventListener('click', function() {
    downloadCanvas(this, 'canvas', 'test.png');
}, false);

function downloadCanvas(link, canvasId, filename) {
    link.href = document.getElementById(canvasId).toDataURL();
    link.Download = filename;
}

You can just put this code in console in firefox or chrom and after changed your canvas tag ID in this above script and run this script in console.

After the execute this code you will see the link as text "click here" at bottom of the html page. click on this link and open the canvas drawing as a PNG image in new window save the image.

json_encode is available in php > 5.2.0:

echojson_encode($row);

Here's an alternative.

1. In XCode4 double-click your Project (Blueprint Icon).
2. Select the Target (Gray Icon)
3. Select the Build Phases (Top Center)
4. Add Build Phase "Run Script" (Green Plus Button, bottom right)
5. In the textbox below the Shell textfield replace "Type a script or drag a script file from your workspace" with "open ${TARGET_BUILD_DIR}/${TARGET_NAME}"

This will open a terminal window with your command-line app running in it.

This is not a great solution because XCode 4 still runs and debugs the app independently of what you're doing in the terminal window that pops up.

One way would be to look for the "ProgramFiles(x86)" environment variable:

String x86folder = Environment.GetEnvironmentVariable("ProgramFiles(x86)");

There's actually a pretty sollution:

function updateArray(context, targetName, callback) {
    context[targetName] = context[targetName].map(callback);
}

var myArray = ['a', 'b', 'c'];
updateArray(this, 'myArray', item => {return '_' + item});

console.log(myArray); //(3) ["_a", "_b", "_c"]

To my knowledge, which, to be fair, is fairly new and limited, the only potential issue with this technique is the fact that you are prevented from dynamically creating some table elements.

I use a form to templating by adding "template" elements to a hidden DIV and then using cloneNode(true) to create a clone and appending it as required. Bear in ind that you do need to ensure you re-assign id's as required to prevent duplication.

By adding a callback argument, you are telling jQuery that you want to make a request for JSONP using a script element instead of a request for JSON using XMLHttpRequest.

JSONP is not JSON. It is a JavaScript program.

Change your server so it outputs the right MIME type for JSONP which is application/javascript.

(While you are at it, stop telling jQuery that you are expecting JSON as that is contradictory: dataType: 'jsonp').

This code should work for you:

 $PHPExcel->getActiveSheet()
        ->getStyle('A1')
        ->getFill()
        ->setFillType(PHPExcel_Style_Fill::FILL_SOLID)
        ->getStartColor()
        ->setRGB('FF0000')

But if you bother using this over and over again, I recommend using applyFromArray.
