Programs & Examples On #Openjdk

You may find OpenJDK 6 and 7 binaries for Windows in openjdk-unofficial-builds github project.

Update: OpenJDK 8 and 11 LTS binaries for Windows x86_64 can be found in ojdkbuild github project.

Disclaimer: I've built them myself.

Update (2019): OpenJDK Updates Project Builds for 8 and 11 are available now.

Appears to be a duplicate of https://askubuntu.com/questions/21131/how-to-correctly-remove-openjdk-and-jre-and-set-the-system-use-only-and-only-sun#answer-21137 assuming that you are using Ubuntu.

The key is to use the command sudo update-java-alternatives -s java-6-sun. Any commands that rely on javac will be affected and not just Maven.

JavaFX is part of OpenJDK

The JavaFX project itself is open source and is part of the OpenJDK project.

Update Dec 2019

For current information on how to use Open Source JavaFX, visit https://openjfx.io. This includes instructions on using JavaFX as a modular library accessed from an existing JDK (such as an Open JDK installation).

The open source code repository for JavaFX is at https://github.com/openjdk/jfx.

At the source location linked, you can find license files for open JavaFX (currently this license matches the license for OpenJDK: GPL+classpath exception).

The wiki for the project is located at: https://wiki.openjdk.java.net/display/OpenJFX/Main

If you want a quick start to using open JavaFX, the Belsoft Liberica JDK distributions provide pre-built binaries of OpenJDK that (currently) include open JavaFX for a variety of platforms.

For distribution as self-contained applications, Java 14, is scheduled to implement JEP 343: Packaging Tool, which "Supports native packaging formats to give end users a natural installation experience. These formats include msi and exe on Windows, pkg and dmg on macOS, and deb and rpm on Linux.", for deployment of OpenJFX based applications with native installers and no additional platform dependencies (such as a pre-installed JDK).

Older information which may become outdated over time

Building JavaFX from the OpenJDK repository

You can build an open version of OpenJDK (including JavaFX) completely from source which has no dependencies on the Oracle JDK or closed source code.

Update: Using a JavaFX distribution pre-built from OpenJDK sources

As noted in comments to this question and in another answer, the Debian Linux distributions offer a JavaFX binary distibution based upon OpenJDK:

• https://packages.qa.debian.org/o/openjfx.html

• Install via:

  sudo apt-get install openjfx
  

(currently this only works for Java 8 as far as I know).

Differences between Open JDK and Oracle JDK with respect to JavaFX

The following information was provided for Java 8. As of Java 9, VP6 encoding is deprecated for JavaFX and the Oracle WebStart/Browser embedded application deployment technology is also deprecated. So future versions of JavaFX, even if they are distributed by Oracle, will likely not include any technology which is not open source.

Oracle JDK includes some software which is not usable from the OpenJDK. There are two main components which relate to JavaFX.

1. The ON2 VP6 video codec, which is owned by Google and Google has not open sourced.
2. The Oracle WebStart/Browser Embedded application deployment technology.

This means that an open version of JavaFX cannot play VP6 FLV files. This is not a big loss as it is difficult to find VP6 encoders or media encoded in VP6.

Other more common video formats, such as H.264 will playback fine with an open version of JavaFX (as long as you have the appropriate codecs pre-installed on the target machine).

The lack of WebStart/Browser Embedded deployment technology is really something to do with OpenJDK itself rather than JavaFX specifically. This technology can be used to deploy non-JavaFX applications.

It would be great if the OpenSource community developed a deployment technology for Java (and other software) which completely replaced WebStart and Browser Embedded deployment methods, allowing a nice light-weight, low impact user experience for application distribution. I believe there have been some projects started to serve such a goal, but they have not yet reached a high maturity and adoption level.

Personally, I feel that WebStart/Browser Embedded deployments are legacy technology and there are currently better ways to deploy many JavaFX applications (such as self-contained applications).

Update Dec, 2019:

An open source version of WebStart for JDK 11+ has been developed and is available at https://openwebstart.com.

Who needs to create Linux OpenJDK Distributions which include JavaFX

It is up to the people which create packages for Linux distributions based upon OpenJDK (e.g. Redhat, Ubuntu etc) to create RPMs for the JDK and JRE that include JavaFX. Those software distributors, then need to place the generated packages in their standard distribution code repositories (e.g. fedora/red hat network yum repositories). Currently this is not being done, but I would be quite surprised if Java 8 Linux packages did not include JavaFX when Java 8 is released in March 2014.

Update, Dec 2019:

Now that JavaFX has been separated from most binary JDK and JRE distributions (including Oracle's distribution) and is, instead, available as either a stand-alone SDK, set of jmods or as a library dependencies available from the central Maven repository (as outlined as https://openjfx.io), there is less of a need for standard Linux OpenJDK distributions to include JavaFX.

If you want a pre-built JDK which includes JavaFX, consider the Liberica JDK distributions, which are provided for a variety of platforms.

Advice on Deployment for Substantial Applications

I advise using Java's self-contained application deployment mode.

A description of this deployment mode is:

Application is installed on the local drive and runs as a standalone program using a private copy of Java and JavaFX runtimes. The application can be launched in the same way as other native applications for that operating system, for example using a desktop shortcut or menu entry.

You can build a self-contained application either from the Oracle JDK distribution or from an OpenJDK build which includes JavaFX. It currently easier to do so with an Oracle JDK.

As a version of Java is bundled with your application, you don't have to care about what version of Java may have been pre-installed on the machine, what capabilities it has and whether or not it is compatible with your program. Instead, you can test your application against an exact Java runtime version, and distribute that with your application. The user experience for deploying your application will be the same as installing a native application on their machine (e.g. a windows .exe or .msi installed, an OS X .dmg, a linux .rpm or .deb).

Note: The self-contained application feature was only available for Java 8 and 9, and not for Java 10-13. Java 14, via JEP 343: Packaging Tool, is scheduled to again provide support for this feature from OpenJDK distributions.

Update, April 2018: Information on Oracle's current policy towards future developments

• The Future of JavaFX and Other Java Client Roadmap Updates by Donald Smith, Sr. Director of Product Management, Oracle.
• Java Client Roadmap Update - March 2018 an Oracle White Paper.

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

When NeXT were defining the NextStep API (as opposed to the NEXTSTEP operating system), they used the prefix NX, as in NXConstantString. When they were writing the OpenStep specification with Sun (not to be confused with the OPENSTEP operating system) they used the NS prefix, as in NSObject.

I got around this by upgrading both the version of Angular that I was using (from v8 -> v9) and the version of TypeScript (from 3.5.3 -> latest).

Output from subprocess.call() should only be redirected to files.

You should use subprocess.Popen() instead. Then you can pass subprocess.PIPE for the stderr, stdout, and/or stdin parameters and read from the pipes by using the communicate() method:

from subprocess import Popen, PIPE

p = Popen(['program', 'arg1'], stdin=PIPE, stdout=PIPE, stderr=PIPE)
output, err = p.communicate(b"input data that is passed to subprocess' stdin")
rc = p.returncode

The reasoning is that the file-like object used by subprocess.call() must have a real file descriptor, and thus implement the fileno() method. Just using any file-like object won't do the trick.

See here for more info.

No. The most similar concept is most likely a StopIteration exception.

The magic you have been looking for has been added in Rails 6 Now you can upsert (update or insert). For single record use:

Model.upsert(column_name: value)

For multiple records use upsert_all :

Model.upsert_all(column_name: value, unique_by: :column_name)

Note:

• Both methods do not trigger Active Record callbacks or validations
• unique_by => PostgreSQL and SQLite only

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

This is actually more simple than you'd think: "Just" copy the HTML table (that is: The HTML code for the table) into the clipboard. Excel knows how to decode HTML tables; it'll even try to preserve the attributes.

The hard part is "copy the table into the clipboard" since there is no standard way to access the clipboard from JavaScript. See this blog post: Accessing the System Clipboard with JavaScript – A Holy Grail?

Now all you need is the table as HTML. I suggest jQuery and the html() method.

Worked for me:

kubectl logs -n namespace -l app=label -c container

try this

    if ($host !~* ^www\.){
        rewrite ^(.*)$ https://www.yoursite.com$1;
    }

Other way: Nginx no-www to www

server {
  listen       80;
  server_name  yoursite.com;
  root /path/;
  index index.php;
  return       301 https://www.yoursite.com$request_uri;
}

and www to no-www

server {
  listen       80;
  server_name  www.yoursite.com;
  root /path/;
  index index.php;
  return       301 https://yoursite.com$request_uri;
}

With a BorderLayout you need to use setPreferredSize instead of setSize

you can simply add a method (setAttributes, with "s" at the end) to "Element" prototype like:

Element.prototype.setAttributes = function(obj){
  for(var prop in obj) {
    this.setAttribute(prop, obj[prop])
  }
}

you can define it in one line:

Element.prototype.setAttributes = function(obj){ for(var prop in obj) this.setAttribute(prop, obj[prop]) }

and you can call it normally as you call the other methods. The attributes are given as an object:

elem.setAttributes({"src": "http://example.com/something.jpeg", "height": "100%", "width": "100%"})

you can add an if statement to throw an error if the given argument is not an object.

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

As this very useful tutorial says:

var age = 0;

// bad
var hasAge = new Boolean(age);

// good
var hasAge = Boolean(age);

// good
var hasAge = !!age;

I made a jsben.ch for you http://jsben.ch/#/aWxtF ...seems that indexOf is a bit faster.

I'm sure there's a better way to achieve this and I would like to read about it, but a workaround I can think of is this:

1. Install the package on a different machine.
2. Copy the rm'ed directory to the original machine (ssh, ftp, whatever).
3. pip uninstall the package (should work again then).

But, yes, I'd also love to hear about a decent solution for this situation.

Static files should be served from resources, not from controller.

Spring Boot will automatically add static web resources located within any of the following directories:

/META-INF/resources/  
/resources/  
/static/  
/public/

string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);

If you have a single character delimiter (like for instance ,), you can reduce that to (note the single quotes):

string[] tokens = str.Split(',');

@MaxPython The answer above is missing ":"

You need the MySQLi module. This error usually occurs when manually installing phpMyAdmin.

sudo apt-get install php7.3-mysql

It will return you with.

[Creating config file /etc/php/7.3/mods-available/mysqlnd.ini with new version]

[Creating config file /etc/php/7.3/mods-available/mysqli.ini with new version]

Then.

sudo service apache2 restart.

Then.

WARNING: Not for git newbies.

This comes up enough in my workflow that I've almost tried to write a new git command for it. The usual git stash flow is the way to go but is a little awkward. I usually make a new commit first since if I have been looking at the changes, all the information is fresh in my mind and it's better to just start git commit-ing what I found (usually a bugfix belonging on master that I discover while working on a feature branch) right away.

It is also helpful—if you run into situations like this a lot—to have another working directory alongside your current one that always have the master branch checked out.

So how I achieve this goes like this:

1. git commit the changes right away with a good commit message.
2. git reset HEAD~1 to undo the commit from current branch.
3. (optional) continue working on the feature.

Sometimes later (asynchronously), or immediately in another terminal window:

1. cd my-project-master which is another WD sharing the same .git
2. git reflog to find the bugfix I've just made.
3. git cherry-pick SHA1 of the commit.

Optionally (still asynchronous) you can then rebase (or merge) your feature branch to get the bugfix, usually when you are about to submit a PR and have cleaned your feature branch and WD already:

1. cd my-project which is the main WD I'm working on.
2. git rebase master to get the bugfixes.

This way I can keep working on the feature uninterrupted and not have to worry about git stash-ing anything or having to clean my WD before a git checkout (and then having the check the feature branch backout again.) and still have all my bugfixes goes to master instead of hidden in my feature branch.

IMO git stash and git checkout is a real PIA when you are in the middle of working on some big feature.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

If it is Netbeans, try to uncheck "Compile on save" setting in the project properties (Build -> Compiling). This is the only thing which helped me in a similar situation.

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

...this is obviously performing a 'string' comparison

No - if the date/time format matches the supported format, MySQL performs implicit conversion to convert the value to a DATETIME, based on the column it is being compared to. Same thing happens with:

WHERE int_column = '1'

...where the string value of "1" is converted to an INTeger because int_column's data type is INT, not CHAR/VARCHAR/TEXT.

If you want to explicitly convert the string to a DATETIME, the STR_TO_DATE function would be the best choice:

WHERE expires_at <= STR_TO_DATE('2010-10-15 10:00:00', '%Y-%m-%d %H:%i:%s')

You could use some third party open-source libraries to generated strong typed verified (X)HTML, such as CityLizard Framework or Sharp DOM.

Update For example

html
    [head
        [title["Title of the page"]]
        [meta_(
            content: "text/html;charset=UTF-8",
            http_equiv: "Content-Type")
        ]
        [link_(href: "css/style.css", rel: "stylesheet", type: "text/css")]
        [script_(type: "text/javascript", src: "/JavaScript/jquery-1.4.2.min.js")]
    ]
    [body
        [div
            [h1["Test Form to Test"]]
            [form_(action: "post", id: "Form1")
                [div
                    [label["Parameter"]]
                    [input_(type: "text", value: "Enter value")]
                    [input_(type: "submit", value: "Submit!")]
                ]
            ]
            [div
                [p["Textual description of the footer"]]
                [a_(href: "http://google.com/")
                    [span["You can find us here"]]
                ]
                [div["Another nested container"]]
            ]
        ]
    ];

net stop <your service> && net start <your service>

No net restart, unfortunately.

If you don't really need the mechanism, just specify a random flavor dimension in your build.gradle:

android { 
    ...
    flavorDimensions "default"
    ...
}

This is how I got it to work cross browser using a combination of the methods above (I also needed to insert images dynamically into the dom):

$('#domTarget').html('<img src="" />');

var url = '/some/image/path.png';

$('#domTarget img').load(function(){}).attr('src', url).error(function() {
    if ( isIE ) {
       var thisImg = this;
       setTimeout(function() {
          if ( ! thisImg.complete ) {
             $(thisImg).attr('src', '/web/css/img/picture-broken-url.png');
          }
       },250);
    } else {
       $(this).attr('src', '/web/css/img/picture-broken-url.png');
    }
});

Note: You will need to supply a valid boolean state for the isIE variable.

As of current edited version of the post, you call setInterval at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.

You only need to "prime" setInterval once. Remove it from function and place it inside onload instead of direct function call.

You will have to set your custom WebviewClient overriding shouldOverrideUrlLoading method for your webview before loading the url.

mWebView.setWebViewClient(new WebViewClient()
        {
            @SuppressWarnings("deprecation")
            @Override
            public boolean shouldOverrideUrlLoading(WebView webView, String url)
            {
                return shouldOverrideUrlLoading(url);
            }

            @TargetApi(Build.VERSION_CODES.N)
            @Override
            public boolean shouldOverrideUrlLoading(WebView webView, WebResourceRequest request)
            {
                Uri uri = request.getUrl();
                return shouldOverrideUrlLoading(uri.toString());
            }

            private boolean shouldOverrideUrlLoading(final String url)
            {
                Log.i(TAG, "shouldOverrideUrlLoading() URL : " + url);

                // Here put your code

                return true; // Returning True means that application wants to leave the current WebView and handle the url itself, otherwise return false.
            }
        });

I'll describe the way I've stored files, in SQL Server and Oracle. It largely depends on how you are getting the file, in the first place, as to how you will get its contents, and it depends on which database you are using for the content in which you will store it for how you will store it. These are 2 separate database examples with 2 separate methods of getting the file that I used.

SQL Server

Short answer: I used a base64 byte string I converted to a byte[] and store in a varbinary(max) field.

Long answer:

Say you're uploading via a website, so you're using an <input id="myFileControl" type="file" /> control, or React DropZone. To get the file, you're doing something like var myFile = document.getElementById("myFileControl")[0]; or myFile = this.state.files[0];.

From there, I'd get the base64 string using code here: Convert input=file to byte array (use function UploadFile2).

Then I'd get that string, the file name (myFile.name) and type (myFile.type) into a JSON object:

var myJSONObj = {
    file: base64string,
    name: myFile.name,
    type: myFile.type,
}

and post the file to an MVC server backend using XMLHttpRequest, specifying a Content-Type of application/json: xhr.send(JSON.stringify(myJSONObj);. You have to build a ViewModel to bind it with:

public class MyModel
{
    public string file { get; set; }
    public string title { get; set; }
    public string type { get; set; }
}

and specify [FromBody]MyModel myModelObj as the passed in parameter:

[System.Web.Http.HttpPost]  // required to spell it out like this if using ApiController, or it will default to System.Mvc.Http.HttpPost
public virtual ActionResult Post([FromBody]MyModel myModelObj)

Then you can add this into that function and save it using Entity Framework:

MY_ATTACHMENT_TABLE_MODEL tblAtchm = new MY_ATTACHMENT_TABLE_MODEL();
tblAtchm.Name = myModelObj.name;
tblAtchm.Type = myModelObj.type;
tblAtchm.File = System.Convert.FromBase64String(myModelObj.file);
EntityFrameworkContextName ef = new EntityFrameworkContextName();
ef.MY_ATTACHMENT_TABLE_MODEL.Add(tblAtchm);
ef.SaveChanges();

tblAtchm.File = System.Convert.FromBase64String(myModelObj.file); being the operative line.

You would need a model to represent the database table:

public class MY_ATTACHMENT_TABLE_MODEL 
{
    [Key]
    public byte[] File { get; set; }  // notice this change
    public string Name { get; set; }
    public string Type { get; set; }
}

This will save the data into a varbinary(max) field as a byte[]. Name and Type were nvarchar(250) and nvarchar(10), respectively. You could include size by adding it to your table as an int column & MY_ATTACHMENT_TABLE_MODEL as public int Size { get; set;}, and add in the line tblAtchm.Size = System.Convert.FromBase64String(myModelObj.file).Length; above.

Oracle

Short answer: Convert it to a byte[], assign it to an OracleParameter, add it to your OracleCommand, and update your table's BLOB field using a reference to the parameter's ParameterName value: :BlobParameter

Long answer: When I did this for Oracle, I was using an OpenFileDialog and I retrieved and sent the bytes/file information this way:

byte[] array;
OracleParameter param = new OracleParameter();
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
dlg.Filter = "Image Files (*.jpg, *.jpeg, *.jpe)|*.jpg;*.jpeg;*.jpe|Document Files (*.doc, *.docx, *.pdf)|*.doc;*.docx;*.pdf"
if (dlg.ShowDialog().Value == true)
{
    string fileName = dlg.FileName;
    using (FileStream fs = File.OpenRead(fileName)
    {
        array = new byte[fs.Length];
        using (BinaryReader binReader = new BinaryReader(fs))
        {
            array = binReader.ReadBytes((int)fs.Length);
        }

        // Create an OracleParameter to transmit the Blob
        param.OracleDbType = OracleDbType.Blob;
        param.ParameterName = "BlobParameter";
        param.Value = array;  // <-- file bytes are here
    }
    fileName = fileName.Split('\\')[fileName.Split('\\').Length-1]; // gets last segment of the whole path to just get the name

    string fileType = fileName.Split('.')[1];
    if (fileType == "doc" || fileType == "docx" || fileType == "pdf")
        fileType = "application\\" + fileType;
    else
        fileType = "image\\" + fileType;

    // SQL string containing reference to BlobParameter named above
    string sql = String.Format("INSERT INTO YOUR_TABLE (FILE_NAME, FILE_TYPE, FILE_SIZE, FILE_CONTENTS, LAST_MODIFIED) VALUES ('{0}','{1}',{2},:BlobParamerter, SYSDATE)", fileName, fileType, array.Length);

    // Do Oracle Update
    RunCommand(sql, param);
}

And inside the Oracle update, done with ADO:

public void RunCommand(string sql, OracleParameter param)
{
    OracleConnection oraConn = null;
    OracleCommand oraCmd = null;
    try
    {
        string connString = GetConnString();
        oraConn = OracleConnection(connString);
        using (oraConn)
        {
            if (OraConnection.State == ConnectionState.Open)

To those who are stuck wondering why a window flashes and goes away without doing anything, the problem may related to the RELATIVE path in your Python script. e.g. you used ".\". Even the Python script and Excel Workbook is in the same directory, the Current Directory may still be different. If you don't want to modify your code to change it to an absolute path. Just change your current Excel directory before you run the python script by:

ChDir ActiveWorkbook.Path

I'm just giving a example here. If the flash do appear, one of the first issues to check is the Current Working Directory.

If It is simple Session you can apply NULL Check directly Session["emp_num"] != null

But if it's a session of a list Item then You need to apply any one of the following option

Option 1:

if (((List<int>)(Session["emp_num"])) != null && (List<int>)Session["emp_num"])).Count > 0)
 {
 //Your Logic here
 }

Option 2:

List<int> val= Session["emp_num"] as List<int>;  //Get the value from Session.

if (val.FirstOrDefault() != null)
 {
 //Your Logic here
 }

If you want to join the selected lines (you are in visual mode), then just press gJ to join your lines with no spaces whatsoever.

This is described in greater detail on the vi/Vim Stack Exchange site.

After not finding anything to get around "Object must implement IConvertible" exception when using Zyphrax's answer (except for implementing the interface).. I tried something a little bit unconventional and worked for my situation.

Using the Newtonsoft.Json nuget package...

var castedObject = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(myObject), myType);

make a parent div, in css make it float:right then make the child div's position fixed this will make the div stay in its position at all times and on the right

WITH  q AS
        (
        SELECT TOP 1 *
        FROM    mytable
        /* You may want to add ORDER BY here */
        )
DELETE
FROM    q

Note that

DELETE TOP (1)
FROM   mytable

will also work, but, as stated in the documentation:

The rows referenced in the TOP expression used with INSERT, UPDATE, or DELETE are not arranged in any order.

Therefore, it's better to use WITH and an ORDER BY clause, which will let you specify more exactly which row you consider to be the first.

on tables with many rows are two queries probably faster...

SELECT @last_id := MAX(id) FROM table;

SELECT * FROM table WHERE id = @last_id;

It seems you can provide just the local image name, assuming it is in the same folder...

It suffices like:

background-image: url("img1.png")

if element is hide by jquery then use

if($("#elmentid").is(':hidden'))

This is the class where the connection is established and messages are recieved. Make sure to pair the devices before you run the application. If you want to have a slave/master connection, where each slave can only send messages to the master , and the master can broadcast messages to all slaves. You should only pair the master with each slave , but you shouldn't pair the slaves together.

        discoveryButton = (Button) findViewById(R.id.discoveryButton);
        discoveryButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                piconet.startPiconet();
            }
        });

    }

}

And here's the XML Layout :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Button
    android:id="@+id/discoveryButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Discover"
    />

<Button
    android:id="@+id/messageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Send message"
    />

Do not forget to add the following permissions to your Manifest File :

    <uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

One more code sample to showcase this:

void Main()
{


    int k = 0;
    TestPlain(k);
    Console.WriteLine("TestPlain:" + k);

    TestRef(ref k);
    Console.WriteLine("TestRef:" + k);

    string t = "test";

    TestObjPlain(t);
    Console.WriteLine("TestObjPlain:" +t);

    TestObjRef(ref t);
    Console.WriteLine("TestObjRef:" + t);
}

public static void TestPlain(int i)
{
    i = 5;
}

public static void TestRef(ref int i)
{
    i = 5;
}

public static void TestObjPlain(string s)
{
    s = "TestObjPlain";
}

public static void TestObjRef(ref string s)
{
    s = "TestObjRef";
}

And the output:

TestPlain:0

TestRef:5

TestObjPlain:test

TestObjRef:TestObjRef

With me, in the project directory run the following commands.

For react native old version (you will see index.android.js in root):

mkdir -p android/app/src/main/assets && rm -rf android/app/build && react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res && cd android && ./gradlew clean assembleRelease && cd ../

For react native new version (you just see index.js in root):

mkdir -p android/app/src/main/assets && rm -rf android/app/build && react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res && cd android && ./gradlew clean assembleRelease && cd ../

The apk file will be generated at:

I still get this once in a while and it usually works if I unplug it and plug it back in a different port. I'm on Linux but had the same thing happen on Windows before.

Change *.cs to .cs in the excludefileslist.txt

Read the FAQ! Holding C++ data in C can be risky.

In C++, a pointer to an object can be converted to void * without any casts. But it's not true the other way round. You'd need a static_cast to get the original pointer back.

Instead of using this in your current class setClassRoomName("aClassName"); you have to use classroom.setClassRoomName("aClassName");

You have to add the class' and at a point like

yourClassNameWhereTheMethodIs.theMethodsName();

I know it's a really late answer but if someone starts learning Java and randomly sees this post he knows what to do.

If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):

public class ListViewDemoActivity extends AppCompatActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;
    private ListView mListView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_list_view_demo);

        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }

        adapter=new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }

    protected ListView getListView() {
        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }
        return mListView;
    }

    protected void setListAdapter(ListAdapter adapter) {
        getListView().setAdapter(adapter);
    }

    protected ListAdapter getListAdapter() {
        ListAdapter adapter = getListView().getAdapter();
        if (adapter instanceof HeaderViewListAdapter) {
            return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
        } else {
            return adapter;
        }
    }
}

And in you layout instead of using android:id="@android:id/list" you can use android:id="@+id/listDemo"

So now you can have a ListView inside a normal AppCompatActivity.

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

Using newInstance

public static MyDialogFragment newInstance(int num) {
    MyDialogFragment f = new MyDialogFragment();

    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putInt("num", num);
    f.setArguments(args);

    return f;
}

And get the Args like this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");
    ...
}

See the full example here
http://developer.android.com/reference/android/app/DialogFragment.html

Minimal example

And just to make what Mizux said as a minimal example:

main_c.c

#include <stdio.h>

int main(void) {
    puts("hello");
}

main_cpp.cpp

#include <iostream>

int main(void) {
    std::cout << "hello" << std::endl;
}

Then, without any Makefile:

make CFLAGS='-g -O3' \
     CXXFLAGS='-ggdb3 -O0' \
     CPPFLAGS='-DX=1 -DY=2' \
     CCFLAGS='--asdf' \
     main_c \
     main_cpp

runs:

cc -g -O3 -DX=1 -DY=2   main_c.c   -o main_c
g++ -ggdb3 -O0 -DX=1 -DY=2   main_cpp.cpp   -o main_cpp

So we understand that:

• make had implicit rules to make main_c and main_cpp from main_c.c and main_cpp.cpp
• CFLAGS and CPPFLAGS were used as part of the implicit rule for .c compilation
• CXXFLAGS and CPPFLAGS were used as part of the implicit rule for .cpp compilation
• CCFLAGS is not used

Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:

main_c: main_c.c
    $(CC) $(CFLAGS) $(CPPFLAGS) -o $@ $<

main_cpp: main_c.c
    $(CXX) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

to achieve a similar affect to the implicit rules.

We could also name those variables however we want: but since Make already treats them magically in the implicit rules, those make good name choices.

Tested in Ubuntu 16.04, GNU Make 4.1.

I wrote an HTML5 video player around broadway h264 codec (emscripten) that can play live (no delay) h264 video on all browsers (desktop, iOS, ...).

Video stream is sent through websocket to the client, decoded frame per frame and displayed in a canva (using webgl for acceleration)

I used fake UserAgent.

How to use:

from fake_useragent import UserAgent
import requests
   

ua = UserAgent()
print(ua.chrome)
header = {'User-Agent':str(ua.chrome)}
print(header)
url = "https://www.hybrid-analysis.com/recent-submissions?filter=file&sort=^timestamp"
htmlContent = requests.get(url, headers=header)
print(htmlContent)

Output:

On Galaxy S3 Android 4.3 the path I use is ./storage/extSdCard/Card/ and it does the job. Hope it helps,

To round up you can use modulus.

The second part of the equation will add to True if there's a remainder. (True = 1; False = 0)

ex: 3/2

answer=$(((3 / 2) + (3 % 2 > 0)))
echo $answer
2

ex: 100 / 2

answer=$(((100 / 2) + (100 % 2 > 0)))
echo $answer
50

ex: 100 / 3

answer=$(((100 / 3) + (100 % 3 > 0)))
echo $answer
34

Find this tuple:

    import os
    SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))

    TEMPLATES = [
        {
            'BACKEND': 'django.template.backends.django.DjangoTemplates',
            'DIRS': [],
            'APP_DIRS': True,
            'OPTIONS': {
                'context_processors': [
                    'django.template.context_processors.debug',
                    'django.template.context_processors.request',
                    'django.contrib.auth.context_processors.auth',
                    'django.contrib.messages.context_processors.messages',
                ],
            },
        },
    ]

You need to add to 'DIRS' the string

"os.path.join(SETTINGS_PATH, 'templates')"

So altogether you need:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(SETTINGS_PATH, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

Below is code how you can display an output of float data with 2 decimal places in Java:

float ratingValue = 52.98929821f; 
DecimalFormat decimalFormat = new DecimalFormat("#.##");
float twoDigitsFR = Float.valueOf(decimalFormat.format(ratingValue)); // output is 52.98

In my case, Jay D is right. I have to add this before the call.

$.ajaxSetup({
    async: false
});

In my previous code, I have this:

var jsonData= (function() {
    var result;
    $.ajax({
        type:'GET',
        url:'data.txt',
        dataType:'json',
        async:false,
        success:function(data){
            result = data;
        }
    });
    return result;
})();
alert(JSON.stringify(jsonData));

It works find. Then I change to

var jsonData= (function() {
    var result;
    $.getJSON('data.txt', {}, function(data){
      result = data;
    });
    return result;
})();
alert(JSON.stringify(jsonData));

The alert is undefined.

If I add those three lines, the alert shows the data again.

$.ajaxSetup({
    async: false
});
var jsonData= (function() {
    var result;
    $.getJSON('data.txt', {}, function(data){
      result = data;
    });
    return result;
})();
alert(JSON.stringify(jsonData));

Here is my solution:

DataTable datatable = (DataTable)dataset.datatablename;

1. Highlight the range in question.
2. On the Home tab, in the Styles Group, Click "Conditional Formatting".
3. Click "Highlight cell rules"

For the first rule,

Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.

For the second,

Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.

For the third,

Same as the second, except your formula is =".8*" rather than .9.

Using Hex in Apache Commons:

String hexString = "fd00000aa8660b5b010006acdc0100000101000100010000";    
byte[] bytes = Hex.decodeHex(hexString.toCharArray());
System.out.println(new String(bytes, "UTF-8"));

If using Spring's XML schema based configuration, setup in the Spring context like this:

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd">
...
<jee:jndi-lookup id="dbDataSource"
   jndi-name="jdbc/DatabaseName"
   expected-type="javax.sql.DataSource" />

Alternatively, setup using simple bean configuration like this:

<bean id="DatabaseName" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/DatabaseName"/>
</bean>

You can declare the JNDI resource in tomcat's server.xml using something like this:

<GlobalNamingResources>
    <Resource name="jdbc/DatabaseName"
              auth="Container"
              type="javax.sql.DataSource"
              username="dbUser"
              password="dbPassword"
              url="jdbc:postgresql://localhost/dbname"
              driverClassName="org.postgresql.Driver"
              initialSize="20"
              maxWaitMillis="15000"
              maxTotal="75"
              maxIdle="20"
              maxAge="7200000"
              testOnBorrow="true"
              validationQuery="select 1"
              />
</GlobalNamingResources>

And reference the JNDI resource from Tomcat's web context.xml like this:

  <ResourceLink name="jdbc/DatabaseName"
   global="jdbc/DatabaseName"
   type="javax.sql.DataSource"/>

Reference documentation:

• Tomcat 8 JNDI Datasource HOW-TO
• Tomcat 8 Context Resource Links Reference
• Spring 4 JEE JNDI Lookup XML Schema Reference
• Spring 4 JndiObjectFactoryBean Javadoc

Edit: This answer has been updated for Tomcat 8 and Spring 4. There have been a few property name changes for Tomcat's default datasource resource pool setup.

public interface A{
    int x=65;
}
public interface B{
    int x=66;
}
public class D implements A,B {
    public static void main(String[] a){
        System.out.println(x); // which x?
    }
}

Here is the solution.

System.out.println(A.x); // done

I think it is the one reason why interface variable are static.

Don't declare variables inside Interface.

Below works for first tr of the table under thead

table thead tr:first-child {
   background: #f2f2f2;
}

And this works for the first tr of thead and tbody both:

table thead tbody tr:first-child {
   background: #f2f2f2;
}

This happens because the provisioning profile can't find the file for the certificate it is linked to.

To fix:

1. Check which certificate is linked to your provisioning profile by clicking edit on your provisioning profile in the Certificates, Identifiers & Profiles section of the Apple Developer dashboard
2. Download the certificate from the dashboard
3. Double click the file to install it in your keychain
4. Drag the file into Xcode to be extra sure it is linked

The error should be gone now.

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

The right way to do it in SDK V2, without the overload of actually getting the object, is to use S3Client.headObject. Officially backed by AWS Change Log.

Example code:

public boolean exists(String bucket, String key) {
    try {
        HeadObjectResponse headResponse = client
                .headObject(HeadObjectRequest.builder().bucket(bucket).key(key).build());
        return true;
    } catch (NoSuchKeyException e) {
        return false;
    }
}

Thanks for the tip Günter, it got me moving in the right direction. There was a mis-matched spelling of 'color' in my solution which was causing issues and I needed to use 'ngValue' not 'value' in the template html.

Here is the complete solution using objects for the ngModel and select list options and avoiding use of the [selected] attribute.

I have updated the Plunker to show the full working solution. https://plnkr.co/edit/yIVEeLK7PUY4VQFrR48g?p=preview

        this.colours.push(new Colour(1, 'Green'));
        this.colours.push(new Colour(2, 'Pink'));

        this.car = new Car();
        this.car.colour = this.colours[1];        
    }
}

export class Car  
{
    colour:Colour;
}

export class Colour
{
    constructor(id:number, name:string) {
        this.id=id;
        this.name=name;
    }

    id:number;
    name:string;
}

The right way to do this is simple:

def rate(T):
    if (T > 200):
        return 200*exp(-T)
    else:
        return 400*exp(-T)

There is absolutely no advantage to using lambda here. The only thing lambda is good for is allowing you to create anonymous functions and use them in an expression (as opposed to a statement). If you immediately assign the lambda to a variable, it's no longer anonymous, and it's used in a statement, so you're just making your code less readable for no reason.

The rate function defined this way can be stored in an array, passed around, called, etc. in exactly the same way a lambda function could. It'll be exactly the same (except a bit easier to debug, introspect, etc.).

From a comment:

Well the function needed to fit in one line, which i didn't think you could do with a named function?

I can't imagine any good reason why the function would ever need to fit in one line. But sure, you can do that with a named function. Try this in your interpreter:

>>> def foo(x): return x + 1

Also these functions are stored as strings which are then evaluated using "eval" which i wasn't sure how to do with regular functions.

Again, while it's hard to be 100% sure without any clue as to why why you're doing this, I'm at least 99% sure that you have no reason or a bad reason for this. Almost any time you think you want to pass Python functions around as strings and call eval so you can use them, you actually just want to pass Python functions around as functions and use them as functions.

But on the off chance that this really is what you need here: Just use exec instead of eval.

You didn't mention which version of Python you're using. In 3.x, the exec function has the exact same signature as the eval function:

exec(my_function_string, my_globals, my_locals)

In 2.7, exec is a statement, not a function—but you can still write it in the same syntax as in 3.x (as long as you don't try to assign the return value to anything) and it works.

In earlier 2.x (before 2.6, I think?) you have to do it like this instead:

exec my_function_string in my_globals, my_locals

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

I am unsure if the author originally was just asking whether or not this allows duplicate values or if there was an implied question here asking, "How to allow duplicate NULL values while using UNIQUE?" Or "How to only allow one UNIQUE NULL value?"

The question has already been answered, yes you can have duplicate NULL values while using the UNIQUE index.

Since I stumbled upon this answer while searching for "how to allow one UNIQUE NULL value." For anyone else who may stumble upon this question while doing the same, the rest of my answer is for you...

In MySQL you can not have one UNIQUE NULL value, however you can have one UNIQUE empty value by inserting with the value of an empty string.

Warning: Numeric and types other than string may default to 0 or another default value.

Configuration.LazyLoadingEnabled = false; Configuration.ProxyCreationEnabled = false;

these are too effect to speed without AutoDetectChangesEnabled = false; and i advise to use different table header from dbo. generally i use like nop,sop,tbl etc..

You should really check out the tutorial on building an SEO-friendly AngularJS site on the year of moo blog. He walks you through all the steps outlined on Angular's documentation. http://www.yearofmoo.com/2012/11/angularjs-and-seo.html

Using this technique, the search engine sees the expanded HTML instead of the custom tags.

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

I created my markup to insert as a string since it's less code and easier to read than working with the fancy dom stuff.

Then I made it innerHTML of a temporary element just so I could take the one and only child of that element and attach to the body.

var html = '<div>';
html += 'Hello div!';
html += '</div>';

var tempElement = document.createElement('div');
tempElement.innerHTML = html;
document.getElementsByTagName('body')[0].appendChild(tempElement.firstChild);

isEmpty()

      Returns true if this list contains no elements.

http://docs.oracle.com/javase/1.4.2/docs/api/java/util/List.html

You can create the same behavior creating a simple custom editor called DateTime.cshtml, saving it in Views/Shared/EditorTemplates

@model DateTime

@{
    var css = ViewData["class"] ?? "";
    @Html.TextBox("", (Model != DateTime.MinValue? Model.ToString("dd/MM/yyyy") : string.Empty), new { @class = "calendar medium " + css});
}

and in your views

@Html.EditorFor(model => model.StartDate, new { @class = "required" })

Note that in my example I'm hard-coding two css classes and the date format. You can, of course, change that. You also can do the same with others html attributes, like readonly, disabled, etc.

This Code worked for me

List<Object> collection = new List<Object>((IEnumerable<Object>)myObject);

If you are inserting into a single table, you can write your query like this (maybe only in MySQL):

INSERT INTO table1 (First, Last)
VALUES
    ('Fred', 'Smith'),
    ('John', 'Smith'),
    ('Michael', 'Smith'),
    ('Robert', 'Smith');

df['variance'] = df.loc[:,['budget','actual']].sum(axis=1)

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

For .net Core in GET method, you can do like this:

 StringValues value1;
 string DeviceId = string.Empty;

  if (Request.Headers.TryGetValue("param1", out value1))
      {
                DeviceId = value1.FirstOrDefault();
      }

After days trying to find the answer, I finally found

display: table;

There was surprisingly very little information available online about how to actually getting it to work, even here, so on to the "How":

To use this fantastic piece of code, you need to think back to when tables were the only real way to structure HTML, namely the syntax. To get a table with 2 rows and 3 columns, you'd have to do the following:

<table>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
</table>

Similarly to get CSS to do it, you'd use the following:

HTML

<div id="table">
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
</div>

CSS

#table{ 
    display: table; 
}
.tr{ 
    display: table-row; 
}
.td{ 
    display: table-cell; }

As you can see in the JSFiddle example below, the divs in the 3rd column have no content, yet are respecting the auto height set by the text in the first 2 columns. WIN!

http://jsfiddle.net/blyzz/1djs97yv/1/

It's worth noting that display: table; does not work in IE6 or 7 (thanks, FelipeAls), so depending on your needs with regards to browser compatibility, this may not be the answer that you are seeking.

I will provide really simple solution to the problem. Suppose we have two inputs username and password,but we want our handle to be easy and generic ,so we can reuse it and don't write boilerplate code.

I.Our form:

                <form>
                    <input type="text" name = "username" onChange={this.onChange} value={this.state.username}/>
                    <input type="text" name = "password" onChange={this.onChange} value={this.state.password}/>
                    <br></br>
                    <button type="submit">Submit</button>
                </form>

II.Our constructor ,which we want to save our username and password ,so we can access them easily:

constructor(props) {
    super(props);
    this.state = {
        username: '',
        password: ''
    };

    this.onSubmit = this.onSubmit.bind(this);
    this.onChange = this.onChange.bind(this);
}

III.The interesting and "generic" handle with only one onChange event is based on this:

onChange(event) {
    let inputName = event.target.name;
    let value = event.target.value;

    this.setState({[inputName]:value});


    event.preventDefault();
}

Let me explain:

1.When a change is detected the onChange(event) is called

2.Then we get the name parameter of the field and its value:

let inputName = event.target.name; ex: username

let value = event.target.value; ex: itsgosho

3.Based on the name parameter we get our value from the state in the constructor and update it with the value:

this.state['username'] = 'itsgosho'

4.The key to note here is that the name of the field must match with our parameter in the state

Hope I helped someone somehow :)

const oldFunction = params => {
  // do something
};

const clonedFunction = (...args) => oldFunction(...args);

Your method (placing script before the closing body tag)

<script>
   myFunction()
</script>
</body>
</html>

is a reliable way to support old and new browsers.

Try this:

public static void arrayContains(){
    int myArray[]={2,2,5,4,8};

    int length=myArray.length;

    int toFind = 5;
    boolean found = false;

    for(int i = 0; i < length; i++) {
        if(myArray[i]==toFind) {
            found=true;
        }
    }

    System.out.println(myArray.length);
    System.out.println(found); 
}

This is a very old question but I came here due to the same issue, so I am leaving this here to help any others.

I was trying to optimize the query because it was taking over 5 minutes to query the DB due to the amount of data. My query was similar to the accepted answer's query. Pablo's comment pushed me in the right direction and my 5 minute query became 0.016 seconds. So to help any others that are having very long query times try using an uncorrelated subquery.

The example for the OP would be:

SELECT 
    a.report_id, 
    a.computer_id, 
    a.date_entered
FROM reports AS a
    JOIN (
        SELECT report_id, computer_id, MAX(date_entered) as max_date_entered
        FROM reports
        GROUP BY report_id, computer_id
    ) as b
WHERE a.report_id = b.report_id
    AND a.computer_id = b.computer_id
    AND a.date_entered = b.max_date_entered

Thank you Pablo for the comment. You saved me big time!

To simplify things here's a jQuery plugin that can achieve this goal : https://github.com/haggen/readonly

1. Include readonly.js in your project. (also needs jquery)

2. Replace .attr('readonly', 'readonly') with .readonly() instead. That's it.

   For example, change from $(".someClass").attr('readonly', 'readonly'); to $(".someClass").readonly();.

public static bool HasConnection()
{
    try
    {
        System.Net.IPHostEntry i = System.Net.Dns.GetHostEntry("www.google.com");
        return true;
    }
    catch
    {
        return false;
    }
}

That works

It seems your question is very much older. But I just saw it. I searched(not in google) and found My Answer.

So I am writing its solution so that others may get help from it.

Here is my solution.

Unlike the other answers, you don't need to setup environments.

all you need is just to write php index.php if index.php is your file name.

then you will see that, the file compiled and showing it's desired output.

In Laravel 5.5

Working on a similar issue and setting the middleware argument from guest to 'auth' seemed like a more elegant solution.

Edit File: app->http->Controllers->Auth->RegisterController.php

public function __construct()
{
     //replace this
     //$this->middleware('guest');

     //with this argument.
       $this->middleware('auth');
}

I could be wrong though...but it seems more slick than editing the routing with more lines and less shity than simply redirecting the page...at least in this instance, wanting to lock down the registration for guests.

"JSON has a special value called null which can be set on any type of data including arrays, objects, number and boolean types."

"The JSON empty concept applies for arrays and objects...Data object does not have a concept of empty lists. Hence, no action is taken on the data object for those properties."

Here is my source.

You can directly go to Web IDE and upload your folder there.

Steps:

1. Go to Web IDE(Mostly located below the clone option).
2. Create new directory at your path
3. Upload your files and folders

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

If you want to set the form size programmatically, set the form's StartPosition property to Manual. Otherwise the form's own positioning and sizing algorithm will interfere with yours. This is why you are experiencing the problems mentioned in your question.

Example: Here is how I resize the form to a size half-way between its original size and the size of the screen's working area. I also center the form in the working area:

public MainView()
{
    InitializeComponent();

    // StartPosition was set to FormStartPosition.Manual in the properties window.
    Rectangle screen = Screen.PrimaryScreen.WorkingArea;
    int w = Width >= screen.Width ? screen.Width : (screen.Width + Width) / 2;
    int h = Height >= screen.Height ? screen.Height : (screen.Height + Height) / 2;
    this.Location = new Point((screen.Width - w) / 2, (screen.Height - h) / 2);
    this.Size = new Size(w, h);
}

Note that setting WindowState to FormWindowState.Maximized alone does not change the size of the restored window. So the window might look good as long as it is maximized, but when restored, the window size and location can still be wrong. So I suggest setting size and location even when you intend to open the window as maximized.

You need to make the object first, then use [] to set it.

var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);

UPDATE 2018:

If you're able to use ES6 and Babel, you can use this new feature:

{
    [yourKeyVariable]: someValueArray,
}  

You trying to set variable name1, witch type set as strict string (it MUST be string) with value from object field name, witch value type set as optional string (it can be string or undefined, because of question sign). If you really need this behavior, you have to change type of name1 like this:

let name1: string | undefined = person.name;

And it'll be ok;

Just use the constructor for the vector that takes iterators:

std::set<T> s;

//...

std::vector v( s.begin(), s.end() );

Assumes you just want the content of s in v, and there's nothing in v prior to copying the data to it.

f you just want to view a large file rather than edit it, there are a couple of freeware programs that read files a chunk at a time rather than trying to load the entire file in to memory. I use these when I need to read through large ( > 5 GB) files.

You'll have to find the link yourself for that last one because the I can only post a maximum of one hyperlink being a newbie.

in simple word your site has been blocked to access network. may be you have automated some script and it caused your whole website to be blocked. the better way to resolve this is contact that site and tell your issue. if issue is genuine they may consider unblocking

If you don't want to use any object, you can still use setattr() inside your current module:

import sys
current_module = module = sys.modules[__name__]  # i.e the "file" where your code is written
setattr(current_module, 'variable_name', 15)  # 15 is the value you assign to the var
print(variable_name)  # >>> 15, created from a string

Use the "REPLACE" string function on the column in question:

UPDATE (yourTable)
SET YourColumn = REPLACE(YourColumn, '*', '')
WHERE (your conditions)

Replace the "*" with the character you want to strip out and specify your WHERE clause to match the rows you want to apply the update to.

Of course, the REPLACE function can also be used - as other answerer have shown - in a SELECT statement - from your question, I assumed you were trying to update a table.

Marc

Looks like something is wrong with your data, it isn't in the format you are expecting. It could be a new line character or a blank space in the data that is tinkering with your code.

As for me, curly braces serve as a substitution for concatenation, they are quicker to type and code looks cleaner. Remember to use double quotes (" ") as their content is parsed by PHP, because in single quotes (' ') you'll get the literal name of variable provided:

<?php

 $a = '12345';

// This works:
 echo "qwe{$a}rty"; // qwe12345rty, using braces
 echo "qwe" . $a . "rty"; // qwe12345rty, concatenation used

// Does not work:
 echo 'qwe{$a}rty'; // qwe{$a}rty, single quotes are not parsed
 echo "qwe$arty"; // qwe, because $a became $arty, which is undefined

?>

Use jQuery:

$("li").find("p").html()

should work.

Try this:

Import-Module Webadministration
Get-ChildItem -Path IIS:\Sites

It should return something that looks like this:

Name             ID   State      Physical Path                  Bindings
----             --   -----      -------------                  --------
ChristophersWeb 22   Started    C:\temp             http *:8080:ChristophersWebsite.ChDom.com

From here you can refine results, but be careful. A pipe to the select statement will not give you what you need. Based on your requirements I would build a custom object or hashtable.

I guess I am coming late, but this info might be useful to anyone I found out something, which might be simple but important. if you use export on a function directly i.e

export const addPost = (id) =>{
  ...
 }

Note while importing you need to wrap it in curly braces i.e. import {addPost} from '../URL';

But when using export default i.e

const addPost = (id) =>{
  ...
 }

export default addPost,

Then you can import without curly braces i.e. import addPost from '../url';

export default addPost

I hope this helps anyone who got confused as me.

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

For figures you can use the method described here :
http://texblog.net/latex-archive/layout/centering-figure-table/
namely, do something like this:

\begin{figure}[h]
\makebox[\textwidth]{%
        \includegraphics[width=1.5\linewidth]{bla.png}
    }
\end{figure}

Notice that if you have subfigures in the figure, you'll probably want to enter into paragraph mode inside the box, like so:

\begin{figure}[h]
\makebox[\textwidth]{\parbox{1.5\textwidth}{ %
\centering
\subfigure[]{\includegraphics[width=0.7\textwidth]{a.png}}
\subfigure[]{\includegraphics[width=0.7\textwidth]{b.png}}
\end{figure}

For allowing the figure to be centered in the page, protruding into both margins rather than only the right margin.
This usually does the trick for images. Notice that with this method, the caption of the image will still be in the delimited by the normal margins of the page (which is a good thing).

well if you really need a curl equivalent you can try node-curl

npm install node-curl

you will probably need to add libcurl4-gnutls-dev.

try checking whether it returns some boolean value then you can simply put it as a condition. I encountered this with the oci_execute(...) which was returning some violation with my unique keys.

ex.
oci_parse($res, "[oracle pl/sql]");
if(oci_execute){
...do something
}

In response to @MiniQuark's answer:

I was trying to read in a csv file that was half-French (containing accents) and also some strings which would eventually become integers and floats. As a test, I created a test.txt file that looked like this:

Montréal, über, 12.89, Mère, Françoise, noël, 889

I had to include lines 2 and 3 to get it to work (which I found in a python ticket), as well as incorporate @Jabba's comment:

import sys 
reload(sys) 
sys.setdefaultencoding("utf-8")
import csv
import unicodedata

def remove_accents(input_str):
    nkfd_form = unicodedata.normalize('NFKD', unicode(input_str))
    return u"".join([c for c in nkfd_form if not unicodedata.combining(c)])

with open('test.txt') as f:
    read = csv.reader(f)
    for row in read:
        for element in row:
            print remove_accents(element)

The result:

Montreal
uber
12.89
Mere
Francoise
noel
889

(Note: I am on Mac OS X 10.8.4 and using Python 2.7.3)

require(gdata)
keep(object_1,...,object_n,sure=TRUE)
ls()

How about adding a space in the pattern attribute like pattern="[a-zA-Z0-9 ]+". If you want to support any kind of space try pattern="[a-zA-Z0-9\s]+"

That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.

To change your Platform Toolset:

1. Right click your project, go to Properties.
2. Under Configuration Properties, go to General.
3. Change your Platform Toolset to one of the available ones.

For future reference, the above code does not work with Python 3. For Python 3, the D.keys() needs to be converted to a list.

import matplotlib.pyplot as plt

D = {u'Label1':26, u'Label2': 17, u'Label3':30}

plt.bar(range(len(D)), D.values(), align='center')
plt.xticks(range(len(D)), list(D.keys()))

plt.show()

The two examples you've given are very simple; they can be represented as a simple interval (the first being four days, the second being 14 days). How you model this will depend entirely on the complexity of your recurrences. If what you have above is truly that simple, then store a start date and the number of days in the repeat interval.

If, however, you need to support things like

Event A repeats every month on the 3rd of the month starting on March 3, 2011

Or

Event A repeats second Friday of the month starting on March 11, 2011

Then that's a much more complex pattern.

This Method to get Google Username:

 public String getUsername() {
    AccountManager manager = AccountManager.get(this);
    Account[] accounts = manager.getAccountsByType("com.google");
    List<String> possibleEmails = new LinkedList<String>();

    for (Account account : accounts) {
        // TODO: Check possibleEmail against an email regex or treat
        // account.name as an email address only for certain account.type
        // values.
        possibleEmails.add(account.name);
    }

    if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
        String email = possibleEmails.get(0);
        String[] parts = email.split("@");
        if (parts.length > 0 && parts[0] != null)
            return parts[0];
        else
            return null;
    } else
        return null;
}

And Get Google User in Gmail id::

 accounts = AccountManager.get(this).getAccounts();
    Log.e("", "Size: " + accounts.length);
    for (Account account : accounts) {

        String possibleEmail = account.name;
        String type = account.type;

        if (type.equals("com.google")) {
            strGmail = possibleEmail;

            Log.e("", "Emails: " + strGmail);
            break;
        }
    }

After add permission in manifest;

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.GET_ACCOUNTS" />

One of the most elegant solution to this problem is to use boost::lexical_cast as @Evgeny Lazin mentioned.

If you just need to test some of the concrete methods without touching any of the abstracts, you can use CALLS_REAL_METHODS (see Morten's answer), but if the concrete method under test calls some of the abstracts, or unimplemented interface methods, this won't work -- Mockito will complain "Cannot call real method on java interface."

(Yes, it's a lousy design, but some frameworks, e.g. Tapestry 4, kind of force it on you.)

The workaround is to reverse this approach -- use the ordinary mock behavior (i.e., everything's mocked/stubbed) and use doCallRealMethod() to explicitly call out the concrete method under test. E.g.

public abstract class MyClass {
    @SomeDependencyInjectionOrSomething
    public abstract MyDependency getDependency();

    public void myMethod() {
        MyDependency dep = getDependency();
        dep.doSomething();
    }
}

public class MyClassTest {
    @Test
    public void myMethodDoesSomethingWithDependency() {
        MyDependency theDependency = mock(MyDependency.class);

        MyClass myInstance = mock(MyClass.class);

        // can't do this with CALLS_REAL_METHODS
        when(myInstance.getDependency()).thenReturn(theDependency);

        doCallRealMethod().when(myInstance).myMethod();
        myInstance.myMethod();

        verify(theDependency, times(1)).doSomething();
    }
}

Updated to add:

For non-void methods, you'll need to use thenCallRealMethod() instead, e.g.:

when(myInstance.myNonVoidMethod(someArgument)).thenCallRealMethod();

Otherwise Mockito will complain "Unfinished stubbing detected."

Use the CSS property list-style-position to position the bullet:

list-style-position:inside /* or outside */;

You can use the following function:

function format(number, decimals = 2, decimalSeparator = '.', thousandsSeparator = ',') {_x000D_
  const roundedNumber = number.toFixed(decimals);_x000D_
  let integerPart = '',_x000D_
    fractionalPart = '';_x000D_
  if (decimals == 0) {_x000D_
    integerPart = roundedNumber;_x000D_
    decimalSeparator = '';_x000D_
  } else {_x000D_
    let numberParts = roundedNumber.split('.');_x000D_
    integerPart = numberParts[0];_x000D_
    fractionalPart = numberParts[1];_x000D_
  }_x000D_
  integerPart = integerPart.replace(/(\d)(?=(\d{3})+(?!\d))/g, `$1${thousandsSeparator}`);_x000D_
  return `${integerPart}${decimalSeparator}${fractionalPart}`;_x000D_
}_x000D_
_x000D_
// Use Example_x000D_
_x000D_
let min = 1556454.0001;_x000D_
let max = 15556982.9999;_x000D_
_x000D_
console.time('number format');_x000D_
for (let i = 0; i < 15; i++) {_x000D_
  let randomNumber = Math.random() * (max - min) + min;_x000D_
  let formated = format(randomNumber, 4, ',', '.'); // formated number_x000D_
_x000D_
  console.log('number: ', randomNumber, '; formated: ', formated);_x000D_

I ran into this problem exactly. My select options were vertically centered in webkit, but ff defaulted them to the top. After looking around I didn't really want to create a work around that was messy and ultimately didn't solve my problem.

Solution: Javascript.

if ($.browser.mozilla) {
            $('.styledSelect select').css( "padding-top","8px" );
        }

This solves your problem very precisely. The only downside here is that I'm using jQuery, and if you aren't using jQuery on your project already, you may not want to include a js library for a one-off.

Note: I don't recommend styling anything with js unless absolutely necessary. CSS should always be the primary solution for styling–think of jQuery (in this particular example) as the axe labeled "Break in case of Emergency".

*UPDATE* This is an old post and since it appears people are still referencing this solution I should state (as mentioned in the comments) that since 1.9 this feature has been removed from jQuery. Please see the Modernizr project to perform feature detection in lieu of browser sniffing.

I had the same error but finally I solved it by suppressing PHP errors Just put this code error_reporting(0); at the top of your print page

    <?php 
    error_reporting(0); //hide php errors
    if( ! defined('BASEPATH')) exit('No direct script access allowed');
    require_once dirname(__FILE__) . '/tohtml/tcpdf/tcpdf.php';
    .... //continue

Very old question, but in case someone else stumbles across it, I would recommend trying:

$j("html, body").stop(true, true).animate({
        scrollTop: $j('#main').offset().top 
}, 300);

Yesterday, I am able to share the folders from my host OS Macbook (high Sierra) to Guest OS Windows 10

Original Answer

Because there isn't an official answer yet and I literally just did this for my OS X/WinXP install, here's what I did:

1. VirtualBox Manager: Open the Shared Folders setting and click the '+' icon to add a new folder. Then, populate the Folder Path (or use the drop-down to navigate) with the folder you want shared and make sure "Auto-Mount" and "Make Permanent" are checked.
2. Boot Windows
3. Download the VBoxGuestAdditions_4.0.12.iso from http://download.virtualbox.org/virtualbox/4.0.12/
4. Go to Devices > Optical drives > choose disk image.. choose the one downloaded in step 3
5. Inside host guest OS (Windows 10, in my case) I could see: This PC > CD Drive (D:) Virtual Guest Additions

For now, right click on it, select Properties, the Compatibility tab, and select Windows 8 compatibility there. Much easier than using the compatibility troubleshooting I did initially.

6. reboot the guest OS (Windows 10)
7. Inside host guest OS, you could see the shared folder This PC> shared folder

It worked for me so I thought of sharing with everyone too.

I have solved this as follows:

1. Window > Customize Perspective... (you will see Android and AVD Manager are disabled)

2. Command Groups Availability > Android and AVD Manager > check

3. Tool Bar Visibility > Android and AVD Manager > check

Put the content on google drive and make it download protect. This way people can only see your documents, pictures but cannot download it.

I think this may answer your question.

Non-static method ..... should not be called statically

If the method is not static you need to initialize it like so:

$var = new ClassName();
$var->method();

Or, in PHP 5.4+, you can use this syntax:

(new ClassName)->method();

width and height are used when going the css route.

<!DOCTYPE html>
<html>
    <head>
        <title>Setting Width and Height on Textareas</title>
        <style>
            .comments { width: 300px; height: 75px }
        </style>
    </head>
    <body>
        <textarea class="comments"></textarea>
    </body>
</html>

I was able to do this by using this command:

notepad .gitignore

And it would open the .gitignore file in Notepad.

I got the same problem.

The workaround I did is add the dummy textbox at the top of the dialog container.

<input type="text" style="width: 1px; height: 1px; border: 0px;" />

You can use the parseInt() function to convert the string to a number, e.g:

parseInt($('#elem').css('top'));

Update: (as suggested by Ben): You should give the radix too:

parseInt($('#elem').css('top'), 10);

Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).

I was having the same problem. It turned out that my SQL Server and SQL Server Agent services logon as were running under the Network Services account which didn't have write access to perform the restore of the back up.

I changed both of these services to logon on as Local System Account and this fixed the problem.

When you say "called" I'm going to assume you mean an ID tag.

To make it cross-brower, I wouldn't suggest using the CSS3 [], although it is an option. This being said, give each of your textboxes a class like "tb" and the radio button "rb".

Then:

#divContainer .tb { width: 150px }
#divContainer .rb { width: 20px }

This assumes you are using the same classes elsewhere, if not, this will suffice:

.tb { width: 150px }
.rb { width: 20px }

As @David mentioned, to access anything within the division itself:

#divContainer [element] { ... }

Where [element] is whatever HTML element you need.

It sounds like you want a StackPanel where the final element uses up all the remaining space. But why not use a DockPanel? Decorate the other elements in the DockPanel with DockPanel.Dock="Top", and then your help control can fill the remaining space.

XAML:

<DockPanel Width="200" Height="200" Background="PowderBlue">
    <TextBlock DockPanel.Dock="Top">Something</TextBlock>
    <TextBlock DockPanel.Dock="Top">Something else</TextBlock>
    <DockPanel
        HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch" 
        Height="Auto" 
        Margin="10">

      <GroupBox 
        DockPanel.Dock="Right" 
        Header="Help" 
        Width="100" 
        Background="Beige" 
        VerticalAlignment="Stretch" 
        VerticalContentAlignment="Stretch" 
        Height="Auto">
        <TextBlock Text="This is the help that is available on the news screen." 
                   TextWrapping="Wrap" />
     </GroupBox>

      <StackPanel DockPanel.Dock="Left" Margin="10" 
           Width="Auto" HorizontalAlignment="Stretch">
          <TextBlock Text="Here is the news that should wrap around." 
                     TextWrapping="Wrap"/>
      </StackPanel>
    </DockPanel>
</DockPanel>

If you are on a platform without DockPanel available (e.g. WindowsStore), you can create the same effect with a grid. Here's the above example accomplished using grids instead:

<Grid Width="200" Height="200" Background="PowderBlue">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <StackPanel Grid.Row="0">
        <TextBlock>Something</TextBlock>
        <TextBlock>Something else</TextBlock>
    </StackPanel>
    <Grid Height="Auto" Grid.Row="1" Margin="10">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="100"/>
        </Grid.ColumnDefinitions>
        <GroupBox
            Width="100"
            Height="Auto"
            Grid.Column="1"
            Background="Beige"
            Header="Help">
            <TextBlock Text="This is the help that is available on the news screen." 
              TextWrapping="Wrap"/>
        </GroupBox>
        <StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
            <TextBlock Text="Here is the news that should wrap around." 
              TextWrapping="Wrap"/>
        </StackPanel>
    </Grid>
</Grid>

myFile = open('today','r')

ips = {}

for line in myFile:
    parts = line.split()
    if parts[1] == 'Failure':
        ips.setdefault(parts[0], 0)
        ips[parts[0]] += 1

of = open('failed.py', 'w')
for ip in [k for k, v in ips.iteritems() if v >=5]:
    of.write(k+'\n')

Check out setdefault, it makes the code a little more legible. Then you dump your data with the file object's write method.

My preferred solution:

function processArray(arr, fn) {
    return arr.reduce(
        (p, v) => p.then((a) => fn(v).then(r => a.concat([r]))),
        Promise.resolve([])
    );
}

It's not fundamentally different from others published here but:

• Applies the function to items in series
• Resolves to an array of results
• Doesn't require async/await (support is still quite limited, circa 2017)
• Uses arrow functions; nice and concise

Example usage:

const numbers = [0, 4, 20, 100];
const multiplyBy3 = (x) => new Promise(res => res(x * 3));

// Prints [ 0, 12, 60, 300 ]
processArray(numbers, multiplyBy3).then(console.log);

Tested on reasonable current Chrome (v59) and NodeJS (v8.1.2).

You can do something like

var notSent = MsgSent.Except(MsgList, MsgIdEqualityComparer);

You will need to provide a custom equality comparer as outlined on MSDN

http://msdn.microsoft.com/en-us/library/bb336390.aspx

Simply have that equality comparer base equality only on MsgID property of each respective type. Since the equality comparer compares two instances of the same type, you would need to define an interface or common base type that both Sent and Messages implement that has a MsgID property.

Combining @jamylak and @jpaddison3's answers together, if you need to be robust against numpy arrays as the input and handle them in the same way as lists, you should use

import numpy as np
isinstance(P, (list, tuple, np.ndarray))

This is robust against subclasses of list, tuple and numpy arrays.

And if you want to be robust against all other subclasses of sequence as well (not just list and tuple), use

import collections
import numpy as np
isinstance(P, (collections.Sequence, np.ndarray))

Why should you do things this way with isinstance and not compare type(P) with a target value? Here is an example, where we make and study the behaviour of NewList, a trivial subclass of list.

>>> class NewList(list):
...     isThisAList = '???'
... 
>>> x = NewList([0,1])
>>> y = list([0,1])
>>> print x
[0, 1]
>>> print y
[0, 1]
>>> x==y
True
>>> type(x)
<class '__main__.NewList'>
>>> type(x) is list
False
>>> type(y) is list
True
>>> type(x).__name__
'NewList'
>>> isinstance(x, list)
True

Despite x and y comparing as equal, handling them by type would result in different behaviour. However, since x is an instance of a subclass of list, using isinstance(x,list) gives the desired behaviour and treats x and y in the same manner.

If you have the connectivity between servers it is better to set up replication (which is trivial, unlike with SQL) with the new instance as a slave node - then you can switch the new node to master with a single command and do the move with zero downtime.

In my case the error was: CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 ....

With eclipse luna from console in the pom.xml folder

mvn clean
mvn install

With Juno I had to had this to my pom.xml

          </configuration>

      </plugins>
    </pluginManagement>
  </build>

And then

mvn install

And then from eclipse right click>maven>update project * Once the plugin is donwloaded you can remove the plugin from your pom.xml

Put file inside while True like so

while True:
     f = open('torecv.png','wb')
     c, addr = s.accept()     # Establish connection with client.
     print 'Got connection from', addr
     print "Receiving..."
     l = c.recv(1024)
     while (l):
         print "Receiving..."
         f.write(l)
         l = c.recv(1024)
     f.close()
     print "Done Receiving"
     c.send('Thank you for connecting')
     c.close()   

An example,

 d <- data.frame(x1=rnorm(10),
                 x2=rnorm(10),
                 x3=rnorm(10))
cor(d) # get correlations (returns matrix)

important:
after any changes or new settings you must restart SQLSERVER service. run services.msc on Windows

There might be a fix to <input type="button"> - but if there is, I don't know it.

Otherwise, a good option seems to be to replace it with a carefully styled a element.

Example: http://jsfiddle.net/Uka5v/

.button {
    background-color: #E3E1B8; 
    padding: 2px 4px;
    font: 13px sans-serif;
    text-decoration: none;
    border: 1px solid #000;
    border-color: #aaa #444 #444 #aaa;
    color: #000
}

Upsides include that the a element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)

Pass your arguments in constructor itself.

Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe","param1","param2").start();

The API of java.io.File only supports getting the last modified time. And the Internet is very quiet on this topic as well.

Unless I missed something significant, the Java library as is (up to but not yet including Java 7) does not include this capability. So if you were desperate for this, one solution would be to write some C(++) code to call system routines and call it using JNI. Most of this work seems to be already done for you in a library called JNA, though.

You may still need to do a little OS specific coding in Java for this, though, as you'll probably not find the same system calls available in Windows and Unix/Linux/BSD/OS X.

Took me a while to read through the above. This was the answer for me:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=False
)

plt.legend(title='Smoker', loc='upper left', labels=['Hell Yeh', 'Nah Bruh'])
plt.show(g)

Reference this for more arguments: matplotlib.pyplot.legend

Just correct Google play services dependencies:

You are including all play services in your project. Only add those you want.

For example , if you are using only maps and g+ signin, than change

 compile 'com.google.android.gms:play-services:8.1.0'

to

compile 'com.google.android.gms:play-services-maps:8.1.0'
compile 'com.google.android.gms:play-services-plus:8.1.0'

From the doc :

In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. In some cases, doing so made it more difficult to keep the number of methods in your app (including framework APIs, library methods, and your own code) under the 65,536 limit.

From version 6.5, you can instead selectively compile Google Play service APIs into your app. For example, to include only the Google Fit and Android Wear APIs, replace the following line in your build.gradle file:
compile 'com.google.android.gms:play-services:8.3.0'
with these lines:

compile 'com.google.android.gms:play-services-fitness:8.3.0'
compile 'com.google.android.gms:play-services-wearable:8.3.0'

Whole list can be found here.

just to toss it out for posterity: it can sometimes be preferable to generate a random string using an initial character set string. This is useful if the string is supposed to be entered manually by a human; excluding 0, O, 1, and l can help reduce user error.

var alpha = "abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789"

// generates a random string of fixed size
func srand(size int) string {
    buf := make([]byte, size)
    for i := 0; i < size; i++ {
        buf[i] = alpha[rand.Intn(len(alpha))]
    }
    return string(buf)
}

and I typically set the seed inside of an init() block. They're documented here: http://golang.org/doc/effective_go.html#init

result = M.A1

We had this error on Oracle RAC 11g on Windows, and the solution was to create the same OS directory tree and external file on both nodes.

It depends on the problem.

Adjacency Matrix

• Uses O(n^2) memory
• It is fast to lookup and check for presence or absence of a specific edge
  between any two nodes O(1)
• It is slow to iterate over all edges
• It is slow to add/delete a node; a complex operation O(n^2)
• It is fast to add a new edge O(1)

Adjacency List

• Memory usage depends on the number of edges (not number of nodes),
  which might save a lot of memory if the adjacency matrix is sparse
• Finding the presence or absence of specific edge between any two nodes
  is slightly slower than with the matrix O(k); where k is the number of neighbors nodes
• It is fast to iterate over all edges because you can access any node neighbors directly
• It is fast to add/delete a node; easier than the matrix representation
• It fast to add a new edge O(1)

I used the command pattern that @jk. mentioned, adding a return type:

public interface Callable<I, O> {

    public O call(I input);   
}

In the beaten-up MVC pattern, the Servlet is "C" - controller.

Its main job is to do initial request evaluation and then dispatch the processing based on the initial evaluation to the specific worker. One of the worker's responsibilities may be to setup some presentation layer beans and forward the request to the JSP page to render HTML. So, for this reason alone, you need to pass the request object to the service layer.

I would not, though, start writing raw Servlet classes. The work they do is very predictable and boilerplate, something that framework does very well. Fortunately, there are many available, time-tested candidates ( in the alphabetical order ): Apache Wicket, Java Server Faces, Spring to name a few.

Quoted from http://maven.apache.org/settings.html:

There are two locations where a settings.xml file may live:

The Maven install: $M2_HOME/conf/settings.xml

A user's install: ${user.home}/.m2/settings.xml

So, usually for a specific user you edit

/home/*username*/.m2/settings.xml

To set environment for all local users, you might think about changing the first path.

    Dim x As Integer = 0
    Dim y As Integer = 0
    Dim k = 0
    Dim l = 0
    Dim bm As New Bitmap(p1.Image)
    Dim om As New Bitmap(p1.Image.Width, p1.Image.Height)
    Dim r, g, b As Byte
    Do While x < bm.Width - 1
        y = 0
        l = 0
        Do While y < bm.Height - 1
            r = 255 - bm.GetPixel(x, y).R
            g = 255 - bm.GetPixel(x, y).G
            b = 255 - bm.GetPixel(x, y).B
            om.SetPixel(k, l, Color.FromArgb(r, g, b))
            y += 3
            l += 1
        Loop
        x += 3
        k += 1
    Loop
    p2.Image = om

This works on all current browsers on WinXP. Basically just checking what the current backgrond image is. If it's image1, show image2, otherwise show image1.

The jsapi stuff just loads jQuery from the Google CDN (easier for testing a misc file on the desktop).

The replace is for cross-browser compatibility (opera and ie add quotes to the url and firefox, chrome and safari remove quotes).

<html>
    <head>
        <script src="http://www.google.com/jsapi"></script>
        <script>
          google.load("jquery", "1.2.6");
          google.setOnLoadCallback(function() {
            var original_image = 'url(http://stackoverflow.com/Content/img/wmd/link.png)';
            var second_image = 'url(http://stackoverflow.com/Content/img/wmd/code.png)';

            $('.mydiv').click(function() {
                if ($(this).css('background-image').replace(/"/g, '') == original_image) {
                    $(this).css('background-image', second_image);
                } else {
                    $(this).css('background-image', original_image);
                }

                return false;
            });
          });
        </script>

        <style>
            .mydiv {
                background-image: url('http://stackoverflow.com/Content/img/wmd/link.png');
                width: 100px;
                height: 100px;
            }

For the most part, ApplicationContext is preferred unless you need to save resources, like on a mobile application.

I'm not sure about depending on XML format, but I'm pretty sure the most common implementations of ApplicationContext are the XML ones such as ClassPathXmlApplicationContext, XmlWebApplicationContext, and FileSystemXmlApplicationContext. Those are the only three I've ever used.

If your developing a web app, it's safe to say you'll need to use XmlWebApplicationContext.

If you want your beans to be aware of Spring, you can have them implement BeanFactoryAware and/or ApplicationContextAware for that, so you can use either BeanFactory or ApplicationContext and choose which interface to implement.

From your feature branch (e.g configUpdate) run:

git fetch
git rebase origin/master

Or the shorter form:

git pull --rebase

Why this works:

• git merge branchname takes new commits from the branch branchname, and adds them to the current branch. If necessary, it automatically adds a "Merge" commit on top.

• git rebase branchname takes new commits from the branch branchname, and inserts them "under" your changes. More precisely, it modifies the history of the current branch such that it is based on the tip of branchname, with any changes you made on top of that.

• git pull is basically the same as git fetch; git merge origin/master.

• git pull --rebase is basically the same as git fetch; git rebase origin/master.

So why would you want to use git pull --rebase rather than git pull? Here's a simple example:

• You start working on a new feature.

• By the time you're ready to push your changes, several commits have been pushed by other developers.

• If you git pull (which uses merge), your changes will be buried by the new commits, in addition to an automatically-created merge commit.

• If you git pull --rebase instead, git will fast forward your master to upstream's, then apply your changes on top.

In C++11 and above, you can also initialize std::vector with an initializer list. For example:

using namespace std; // for example only

for (auto s : vector<string>{"one","two","three"} ) 
    cout << s << endl;

So, your example would become:

void foo(vector<string> strArray){
  // some code
}

vector<string> s {"hi", "there"}; // Works
foo(s); // Works

foo(vector<string> {"hi", "there"}); // also works

If you were looking for what to use in android, it is:

String android.text.TextUtils.join(CharSequence delimiter, Object[] tokens)

for example:

String joined = TextUtils.join(";", MyStringArray);

You might be an admin doing a one-off push directly into refs/changes/<change_number>.

For example, once a commit without Change-Id landed into Subversion, you pull it out of Subversion using git-svn, and you'd like to archive it as a Gerrit patchset into a Gerrit change.

If so, you can go to project settings page (http://[installation-path]/#/admin/projects/[project-id]) and temporarily change "Require Change-Id in commit message" value to False.

Don't forget to afterwards change it back to Inherit or True!

Use this pattern "^\d*(\.\d{2}$)?"

hi If you are still not able to make column as AUTO_INCREMENT while creating table. As a work around first create table that is:

create table student( sid integer NOT NULL sname varchar(30), PRIMARY KEY (sid) );

and then explicitly try to alter column bu using the following

alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY

Or

alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY (start with 100)

VLOOKUP deosnt work for String literals

One of the pitfalls as I know is IE problem with custom elements. As quoted from the docs:

3) you do not use custom element tags such as (use the attribute version instead)

4) if you do use custom element tags, then you must take these steps to make IE 8 and below happy

<!doctype html>
  <html xmlns:ng="http://angularjs.org" id="ng-app" ng-app="optionalModuleName">
    <head>
      <!--[if lte IE 8]>
        <script>
          document.createElement('ng-include');
          document.createElement('ng-pluralize');
          document.createElement('ng-view');

          // Optionally these for CSS
          document.createElement('ng:include');
          document.createElement('ng:pluralize');
          document.createElement('ng:view');
        </script>
      <![endif]-->
    </head>
    <body>
      ...
    </body>
  </html>

Try the maven-exec-plugin. From there:

mvn exec:java -Dexec.mainClass="com.example.Main"

This will run your class in the JVM. You can use -Dexec.args="arg0 arg1" to pass arguments.

If you're on Windows, apply quotes for exec.mainClass and exec.args:

mvn exec:java -D"exec.mainClass"="com.example.Main"

If you're doing this regularly, you can add the parameters into the pom.xml as well:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.2.1</version>
  <executions>
    <execution>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>com.example.Main</mainClass>
    <arguments>
      <argument>foo</argument>
      <argument>bar</argument>
    </arguments>
  </configuration>
</plugin>

is this what you want?

var grouped = CustomerList.GroupBy(m => m.GroupID).Select((n) => new { GroupId = n.Key, Items = n.ToList() });

setLoanItem is an instance method, meaning you need an instance of the Media class in order to call it. You're attempting to call it on the Media type itself.

You may want to look into some basic object-oriented tutorials to see how static/instance members work.

you can use autocomplete="off" on parent form, so if you reload your page, checkboxes will not be checked automatically

JavaScript setTimeout is a very good solution:

function funcx()
   {
   // your code here
   // break out here if needed
   setTimeout(funcx, 3000);
   }

funcx();

The delay function in jQuery is mostly used for delaying animations in a jQuery animation queue.

Please post your Model Class.

To check the errors in your ModelState use the following code:

var errors = ModelState
    .Where(x => x.Value.Errors.Count > 0)
    .Select(x => new { x.Key, x.Value.Errors })
    .ToArray();

OR: You can also use

var errors = ModelState.Values.SelectMany(v => v.Errors);

Place a break point at the above line and see what are the errors in your ModelState.

I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:

At web.config file, add the requestTimeout attribute at aspNetCore node.

<system.webServer>
  <aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>

In this example, I'm setting the value for 10 minutes.

To solve this, I created a JS library to stream multiple files directly into a zip on the client-side. The main unique feature is that it has no size limits from memory (everything is streamed) nor zip format (it uses zip64 if the contents are more than 4GB).

Since it doesn't do compression, it is also very performant.

Find "downzip" it on npm or github!

Try this

Console.WriteLine("{0,10}{1,10}{2,10}{3,10}{4,10}",
  customer[DisplayPos],
  sales_figures[DisplayPos],
  fee_payable[DisplayPos], 
  seventy_percent_value,
  thirty_percent_value);

where the first number inside the curly brackets is the index and the second is the alignment. The sign of the second number indicates if the string should be left or right aligned. Use negative numbers for left alignment.

Or look at http://msdn.microsoft.com/en-us/library/aa331875(v=vs.71).aspx

you can check installed c# compilers and the printed version of the .net:

@echo off

for /r "%SystemRoot%\Microsoft.NET\Framework\" %%# in ("*csc.exe") do (
    set "l="
    for /f "skip=1 tokens=2 delims=k" %%$ in ('"%%# #"') do (
        if not defined l (
            echo Installed: %%$
            set l=%%$
        )
    )
)

echo latest installed .NET %l%

the csc.exe does not have a -version switch but it prints the .net version in its logo. You can also try with msbuild.exe but .net framework 1.* does not have msbuild.

To hash a string, use the built-in MessageDigest class:

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.nio.charset.StandardCharsets;
import java.math.BigInteger;

public class CryptoHash {
  public static void main(String[] args) throws NoSuchAlgorithmException {
    MessageDigest md = MessageDigest.getInstance("SHA-256");
    String text = "Text to hash, cryptographically.";

    // Change this to UTF-16 if needed
    md.update(text.getBytes(StandardCharsets.UTF_8));
    byte[] digest = md.digest();

    String hex = String.format("%064x", new BigInteger(1, digest));
    System.out.println(hex);
  }
}

In the snippet above, digest contains the hashed string and hex contains a hexadecimal ASCII string with left zero padding.

In most of the companies they required a common functionality for multiple dropdownlist for all the pages. Just call the functions or pass your (DropDownID,JsonData,KeyValue,textValue)

    <script>

        $(document).ready(function(){

            GetData('DLState',data,'stateid','statename');
        });

        var data = [{"stateid" : "1","statename" : "Mumbai"},
                    {"stateid" : "2","statename" : "Panjab"},
                    {"stateid" : "3","statename" : "Pune"},
                     {"stateid" : "4","statename" : "Nagpur"},
                     {"stateid" : "5","statename" : "kanpur"}];

        var Did=document.getElementById("DLState");

        function GetData(Did,data,valkey,textkey){
          var str= "";
          for (var i = 0; i <data.length ; i++){

            console.log(data);


            str+= "<option value='" + data[i][valkey] + "'>" + data[i][textkey] + "</option>";

          }
          $("#"+Did).append(str);
        };    </script>

Please check whether you have provided js references correctly. JQuery files first and then your custom files. Since you are using '$' in your js methods.

Hudson also allows you to define several Java runtimes, and let you invoke Maven with one of these. Have a closer look on the configuration page.

Have you considered iframes or segregating your content and using a simple show/hide?

Edit If you want to use an iframe, you can have the contents of page1 and page2 in one html file. Then you can decide what to show or hide by reading the location.search property of the iframe. So your code can be like this :

For Page 1 : iframe.src = "mypage.html?show=1"

For Page 2 : iframe.src = "mypage.html?show=2"

Now, when your iframe loads, you can use the location.search.split("=")[1], to get the value of the page number and show the contents accordingly. This is just to show that iframes can also be used but the usage is more complex than the normal show/hide using div structures.

1. Open the eclipse.ini file from your eclipse folder,see the picture below.

2. Open eclipse.ini in Notepad or any other text-editor application, Find the line -Xmx256m (or -Xmx1024m). Now change the default value 256m (or 1024m) to 512m. You also need to give the exact java installed version (1.6 or 1.7 or other).

Like This:

-Xmx512m
-Dosgi.requiredJavaVersion=1.6

OR

-Xmx512m
-Dosgi.requiredJavaVersion=1.7

OR

-Xmx512m
-Dosgi.requiredJavaVersion=1.8

Then it works well for me.

You should really check the log. It seems that quite a few components can cause the Windows SDK installer to fail to install with this useless error message. For instance it could be the Visual C++ Redistributable Package as mentioned there.

I don't see any reason to use Django just to expose a REST api, there are lighter and more flexible solutions. Django carries a lot of other things to the table, that are not always needed. For sure not needed if you only want to expose some code as a REST service.

My personal experience, fwiw, is that once you have a one-size-fits-all framework, you'll start to use its ORM, its plugins, etc. just because it's easy, and in no time you end up having a dependency that is very hard to get rid of.

Choosing a web framework is a tough decision, and I would avoid picking a full stack solution just to expose a REST api.

Now, if you really need/want to use Django, then Piston is a nice REST framework for django apps.

That being said, CherryPy looks really nice too, but seems more RPC than REST.

Looking at the samples (I never used it), probably web.py is the best and cleanest if you only need REST.

downloaded Sql server management 2008 r2 and got it installed. Its getting installed but when I try to connect it via .\SQLEXPRESS it shows error. DO I need to install any SQL service on my system?

You installed management studio which is just a management interface to SQL Server. If you didn't (which is what it seems like) already have SQL Server installed, you'll need to install it in order to have it on your system and use it.
