you already know either it store in bss(block start by symbol) also referred as uninitialized data segment or in initialized data segment.

lets take an simple example

void main(void)
{
static int i;
}

the above static variable is not initialized , so it goes to uninitialized data segment(bss).

void main(void)
{
static int i=10;
}

and of course it initialized by 10 so it goes to initialized data segment.

Just use:

$('#selectedDueDate').val(dateText).trigger('input');

instead of:

$('#selectedDueDate').val(dateText);

In my current organization, we don't do this in master but do do it on both develop and release/ branches (we are using Git Flow), in order to generate snapshot builds.

As we are using a multi branch pipeline, we do this in the Jenkinsfile with the when{} syntax...

stage {
    when { 
        expression { 
            branch 'develop'
        }
    }
}

This is detailed in this blog post: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/#longer-pipeline

Here is the PHP code to check if 'id' parameter exists in the URL or not:

if(isset($_GET['id']))
{
   $slide = $_GET['id'] // Getting parameter value inside PHP variable
}

I hope it will help you.

The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.

Proxy Error

The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /lin/Campaignn.jsp.

As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.

Complete code with error handling and added file stream closes. Add it to your class that you want to be able to serialize and deserialize. In my case the class name is CreateResumeForm. You should change it to your own class name. Android interface Serializable is not sufficient to save your objects to the file, it only creates streams.

// Constant with a file name
public static String fileName = "createResumeForm.ser";

// Serializes an object and saves it to a file
public void saveToFile(Context context) {
    try {
        FileOutputStream fileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);
        objectOutputStream.writeObject(this);
        objectOutputStream.close();
        fileOutputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}


// Creates an object by reading it from a file
public static CreateResumeForm readFromFile(Context context) {
    CreateResumeForm createResumeForm = null;
    try {
        FileInputStream fileInputStream = context.openFileInput(fileName);
        ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
        createResumeForm = (CreateResumeForm) objectInputStream.readObject();
        objectInputStream.close();
        fileInputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    return createResumeForm;
}

Use it like this in your Activity:

form = CreateResumeForm.readFromFile(this);

You need to set the location header as follows:

header('Location: http://www.example.com/');

Replacing http://www.example.com of course with the url of your landing page.

Add this where you have finished logging the user in.

Note: When redirecting the user will be immediately redirected so you're message probably won't display.

Additionally, you need to move your PHP code to the top of the file for this solution to work.

On another side note, please see my comment above regarding the use of the deprecated mysql statements and consider using the newer, safer and improved mysqli or PDO statements.

As I understand it, the selected answer still loads all of the related tests. According to this msdn blog, there is a better way.

http://blogs.msdn.com/b/adonet/archive/2011/01/31/using-dbcontext-in-ef-feature-ctp5-part-6-loading-related-entities.aspx

Specifically

using (var context = new UnicornsContext())

    var princess = context.Princesses.Find(1);

    // Count how many unicorns the princess owns 
    var unicornHaul = context.Entry(princess)
                      .Collection(p => p.Unicorns)
                      .Query()
                      .Count();
}

from sklearn.model_selection import train_test_split
import numpy

with open("datafile.txt", "rb") as f:
   data = f.read().split('\n')
   data = numpy.array(data)  #convert array to numpy type array

   x_train ,x_test = train_test_split(data,test_size=0.5)       #test_size=0.5(whole_data)

Change div to span. And space the icons using   HTML

 <div class="nav3" style="height:705px;">
 <span class="icons"><a href="http://www.facebook.com/"><img src="images/facebook.png"></a>
 </span>&nbsp;&nbsp;&nbsp;
 <span class="icons"><a href="https://twitter.com"><img src="images/twitter.png"></a>
 </span>
 </div>

CSS

.nav3 {
background-color: #E9E8C7;
height: auto;
width: 150px;
float: left;
padding-left: 20px;
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
color: #333333;
padding-top: 20px;
padding-right: 20px;
}

.icons{
display:inline-block;
width: 64px; 
height: 64px; 
}

 a.icons:hover {
 background: #C93;
 }

span does not break line, div does.

The FileInputStream class works directly with the underlying file system. If the file in question is not physically present there, it will fail to open it. The getResourceAsStream() method works differently. It tries to locate and load the resource using the ClassLoader of the class it is called on. This enables it to find, for example, resources embedded into jar files.

Some answers suggested to use pattern: check if role does not exist and if not then issue CREATE ROLE command. This has one disadvantage: race condition. If somebody else creates a new role between check and issuing CREATE ROLE command then CREATE ROLE obviously fails with fatal error.

To solve above problem, more other answers already mentioned usage of PL/pgSQL, issuing CREATE ROLE unconditionally and then catching exceptions from that call. There is just one problem with these solutions. They silently drop any errors, including those which are not generated by fact that role already exists. CREATE ROLE can throw also other errors and simulation IF NOT EXISTS should silence only error when role already exists.

CREATE ROLE throw duplicate_object error when role already exists. And exception handler should catch only this one error. As other answers mentioned it is a good idea to convert fatal error to simple notice. Other PostgreSQL IF NOT EXISTS commands adds , skipping into their message, so for consistency I'm adding it here too.

Here is full SQL code for simulation of CREATE ROLE IF NOT EXISTS with correct exception and sqlstate propagation:

DO $$
BEGIN
CREATE ROLE test;
EXCEPTION WHEN duplicate_object THEN RAISE NOTICE '%, skipping', SQLERRM USING ERRCODE = SQLSTATE;
END
$$;

Test output (called two times via DO and then directly):

$ sudo -u postgres psql

Type "help" for help.

Since I first saw break in C a couple of decades back, this problem has vexed me. I was hoping some language enhancement would have an extension to break which would work thus:

break; // our trusty friend, breaks out of current looping construct.
break 2; // breaks out of the current and it's parent looping construct.
break 3; // breaks out of 3 looping constructs.
break all; // totally decimates any looping constructs in force.

If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.

<input id="addButton" type="button" value="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#addButton').click(function() 
         { 
             showDialog('#addPerson'); 
         });
     });
</script>

If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:

<asp:Button ID="buttonAdd" runat="server" Text="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#<%= buttonAdd.ClientID %>').click(function(e) 
         { 
             showDialog('#addPerson');

             if(/*Some Condition Is Not Met*/) 
                return false;
         });
     });
</script>

If I may add one more solution: you can simply cancel the clipboard with this command:

Application.CutCopyMode = False

For Mysql please see the LOAD XML Syntax^Docs.

It should work without any additional XML transformation for the XML you've provided, just specify the format and define the table inside the database firsthand with matching column names:

LOAD XML LOCAL INFILE 'table1.xml'
    INTO TABLE table1
    ROWS IDENTIFIED BY '<table1>';

There is also a related question:

• How to import XMl file into MySQL database table using XML_LOAD(); function

For Postgresql I do not know.

This one matches everything even if it finds multiple closing curly braces in the middle:

\{([\s\S]*)\}

Example:

{
  "foo": {
    "bar": 1,
    "baz": 1,
  }
}

It is much more accurate to use IndexOf:

If dt.Columns.IndexOf("ColumnName") = -1 Then
    'Column not exist
End If

If the Contains is used it would not differentiate between ColumName and ColumnName2.

These days, socket.on('connect', ...) is not working for me. I use the below code to check at 1st connecting.

if (socket.connected)
  console.log('socket.io is connected.')

and use this code when reconnected.

socket.on('reconnect', ()=>{
  //Your Code Here
});

Might also be interesting for you to know that you can use:

{r echo=FALSE, results='hide',message=FALSE}
a<-as.numeric(rnorm(100))
hist(a, breaks=24)

to exclude all the commands you give, all the results it spits out and all message info being spit out by R (eg. after library(ggplot) or something)

i had the same problem... every time that i wanted to publish my css.. I had to make a search/replace.. and relative path wouldnt work either for me because the relative paths were different from dev to production.

Finally was tired of doing the search/replace and I created a dynamic css, (e.g. www.mysite.com/css.php) it's the same but now i could use my php constants in the css. somethig like

.icon{
  background-image:url('<?php echo BASE_IMAGE;?>icon.png');
}

and it's not a bad idea to make it dynamic because now i could compress it using YUI compressor without loosing the original format on my dev server.

Good Luck!

This kind of leads to the question when you should use a set and when you should use a list. Usually, the advice goes:

1. If you need ordered data, use a List
2. If you need unique data, use a Set
3. If you need both, use either: a SortedSet (for data ordered by comparator) or an OrderedSet/UniqueList (for data ordered by insertion). Unfortunately the Java API does not yet have OrderedSet/UniqueList.

A fourth case that appears often is that you need neither. In this case you see some programmers go with lists and some with sets. Personally I find it very harmful to see set as a list without ordering - because it is really a whole other beast. Unless you need stuff like set uniqueness or set equality, always favor lists.

A minor simplification on the example by @naresh. Should deal with permission issues and offer some clarification.

$data = '<base64_encoded_string>';

$data = base64_decode($data);

$img = imagecreatefromstring($data);

header('Content-Type: image/png');

$file = '<path_to_home_or_user_directory>/decoded_images/test.png';

imagepng($img, $file);

imagedestroy($img);

One possibility is to delete to cookie you are looking for the expiration date from and rewrite it. Then you'll know the expiration date.

If you want an Iterator over an array, you could use one of the direct implementations out there instead of wrapping the array in a List. For example:

Apache Commons Collections ArrayIterator

Or, this one, if you'd like to use generics:

com.Ostermiller.util.ArrayIterator

Note that if you want to have an Iterator over primitive types, you can't, because a primitive type can't be a generic parameter. E.g., if you want an Iterator<int>, you have to use an Iterator<Integer> instead, which will result in a lot of autoboxing and -unboxing if that's backed by an int[].

I guess your elements on the page messes up because you don't clear out your floats, check this out

Demo

HTML

<div class="wrap">
    <div class="floatleft"></div>
    <div class="floatright"></div>
    <div style="clear: both;"></div>
</div>

CSS

.wrap {
    width: 100%;
}

.floatleft {
    float:left; 
    width: 80%;
    background-color: #ff0000;
    height: 400px;
}

.floatright {
float: right;
    background-color: #00ff00;
    height: 400px;
    width: 20%;
}

There is no do-while loop in Python.

This is a similar construct, taken from the link above.

 while True:
     do_something()
     if condition():
        break

You have to use a different background image, not color, for each state of the EditText (focus, enabled, activated).

http://android-holo-colors.com/

In the site above, you can get images from a lot of components in the Holo theme. Just select "EditText" and the color you want. You can see a preview at the bottom of the page.

Download the .zip file, and copy paste the resources in your project (images and the XML).

if your XML is named: apptheme_edit_text_holo_light.xml (or something similar):

1. Go to your XML "styles.xml" and add the custom EditText style:

   <style name="EditTextCustomHolo" parent="android:Widget.EditText">
      <item name="android:background">@drawable/apptheme_edit_text_holo_light</item>
      <item name="android:textColor">#ffffff</item>
   </style>
   

2. Just do this in your EditText:

   <EditText
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      style="@style/EditTextCustomHolo"/>
   

And that's it, I hope it helps you.

if you need to decompile standalone jar try JD-GUI by the same autor (of JD-Eclipse). It is a standalone application (does not need eclipse). It can open both *.class and *.jar files. Interesting enough it needs .Net installed (as do JD-Eclipse indeed), but otherwise works like a charm.

Find it here:

http://jd.benow.ca/

Regards,

From http://www.toptal.com/javascript/interview-questions:

function isInteger(x) { return (x^0) === x; } 

Found it to be the best way to do this.

find . -name foo.txt 1> tmpfile && mv `cat tmpfile` /path/to/some/dir/

is yet another way, albeit dirty.

Linkage. Try this:

extern "C" void *print_message() {...

From what I see you just try to see if they are equal, if this is true, just go with something like this:

boolean areEqual = Arrays.equals(arr1, arr2);

This is the standard way of doing it.

Please note that the arrays must be also sorted to be considered equal, from the JavaDoc:

Two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal. In other words, two arrays are equal if they contain the same elements in the same order.

Sorry for missing that.

You can speed up your Eclipse or Android Studio work, you just follow these:

• Use/open single project at a time
• clean your project after running your app in emulator every time
• use mobile/external device instead of emulator
• don't close emulator after using once, use same emulator for running app each time
• Disable VCS by using File->Settings->Plugins and disable the following things :
  1.CVS Integration
  2.Git Integration
  3.GitHub
  4.Google Cloud Tools for Android Studio
  5.Subversion Integration

I am also using Android Studio with 4-GB installed main memory but following these statements really boost my Android Studio performance.

The null character is '\0', not '/0'.

while (*(forward++) != '\0')

for the background you can easily add a view, like in example:

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)];
view.backgroundColor = [UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:0.1];
[navbar addSubview:view];

where "navbar" is a UINavigationBar.

This is my idea of what you are trying to do and it works fine:

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

    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

    BufferedWriter out = new BufferedWriter(new FileWriter("c://output.txt"));
    try {
        String inputLine = null;
        do {
            inputLine=in.readLine();
            out.write(inputLine);
            out.newLine();
        } while (!inputLine.equalsIgnoreCase("eof"));
        System.out.print("Write Successful");
    } catch(IOException e1) {
        System.out.println("Error during reading/writing");
    } finally {
        out.close();
        in.close();
    }
}

For all those recommending using table variables, be cautious in doing so. Table variable cannot be indexed whereas a temp table can be. A table variable is best when working with small amounts of data but if you are working on larger sets of data (e.g. 50k records) a temp table will be much faster than a table variable.

Also keep in mind that you can't rely on a try/catch to force a cleanup within the stored procedure. certain types of failures cannot be caught within a try/catch (e.g. compile failures due to delayed name resolution) if you want to be really certain you may need to create a wrapper stored procedure that can do a try/catch of the worker stored procedure and do the cleanup there.

e.g. create proc worker AS BEGIN -- do something here END

create proc wrapper AS
BEGIN
    Create table #...
    BEGIN TRY
       exec worker
       exec worker2 -- using same temp table
       -- etc
    END TRY
    END CATCH
       -- handle transaction cleanup here
       drop table #...
    END CATCH 
END

One place where table variables are always useful is they do not get rolled back when a transaction is rolled back. This can be useful for capturing debug data that you want to commit outside the primary transaction.

Do what @Sudhir said, and then to get a String out of the comma seperated list of numbers use:

for (var i=0; i<unitArr.byteLength; i++) {
            myString += String.fromCharCode(unitArr[i])
        }

This will give you the string you want, if it's still relevant

You can try below query,

select * from players
where 
    us_reg_date between '2000-07-05'
and
    DATE_ADD('2011-11-10',INTERVAL 1 DAY)

In June 2018, in an effort to raise security and comply with modern standards, the insecure TLS 1.0 & 1.1 protocols will no longer be supported for SSL connections to Central. This should only affect users of Java 6 (and Java 7) that are also using https to access central, which by our metrics is less than .2% of users.

For more details and workarounds, see the blog and faq here: https://blog.sonatype.com/enhancing-ssl-security-and-http/2-support-for-central

I looked everywhere for an answer and finally this worked for me:

SELECT Lower(Substring(MASTER.dbo.Fn_varbintohexstr(0x21232F297A57A5A743894A0E4A801FC3), 3, 8000))

Outputs to (string):

21232f297a57a5a743894a0e4a801fc3

You can use it in your WHERE or JOIN conditions as well in case you want to compare/match varbinary records with strings

If the content is a variable, it will be necessary to concatenate it with quotation marks. It worked for me. Like this:

itemSelected(id: number){
    console.log('label contains', document.querySelector("label[for='" + id + "']"));
}

In other words, you want to pipe stdout into one filter (tee bbb.out) and stderr into another filter (tee ccc.out). There is no standard way to pipe anything other than stdout into another command, but you can work around that by juggling file descriptors.

{ { ./aaa.sh | tee bbb.out; } 2>&1 1>&3 | tee ccc.out; } 3>&1 1>&2

See also How to grep standard error stream (stderr)? and When would you use an additional file descriptor?

In bash (and ksh and zsh), but not in other POSIX shells such as dash, you can use process substitution:

./aaa.sh > >(tee bbb.out) 2> >(tee ccc.out)

Beware that in bash, this command returns as soon as ./aaa.sh finishes, even if the tee commands are still executed (ksh and zsh do wait for the subprocesses). This may be a problem if you do something like ./aaa.sh > >(tee bbb.out) 2> >(tee ccc.out); process_logs bbb.out ccc.out. In that case, use file descriptor juggling or ksh/zsh instead.

I know it's too late but here I think is cleaner solution that's more readable...

/**
 * method converts {@link InputStream} Object into byte[] array.
 * 
 * @param stream the {@link InputStream} Object.
 * @return the byte[] array representation of received {@link InputStream} Object.
 * @throws IOException if an error occurs.
 */
public static byte[] streamToByteArray(InputStream stream) throws IOException {

    byte[] buffer = new byte[1024];
    ByteArrayOutputStream os = new ByteArrayOutputStream();

    int line = 0;
    // read bytes from stream, and store them in buffer
    while ((line = stream.read(buffer)) != -1) {
        // Writes bytes from byte array (buffer) into output stream.
        os.write(buffer, 0, line);
    }
    stream.close();
    os.flush();
    os.close();
    return os.toByteArray();
}

CSS :

ul{
list-style-type:none;
}

You can take a look at W3School

All javascript methods are applicable with angularjs because angularjs itself is a javascript framework so you can use indexOf() inside angular directives

<li ng-repeat="select in Items">   
         <foo ng-repeat="newin select.values">
<span ng-if="newin.label.indexOf(x) !== -1">{{newin.label}}</span></foo>
</li>
//where x is your character to be found

I was debugging the problem for the better part of the day and when I was close to burning the building I discovered the Process Monitor tool from Sysinternals.

Set it to monitor w3wp.exe and check last events before it exits after you fire a request in the browser. Hope that helps further readers.

If the IDE you use(in case you use one) might have been getting in the way as well. That's what happened to me when using QtCreator.

No, the way that you're doing it is just fine. implode() only takes 1-2 parameters (if you just supply an array, it joins the pieces by an empty string).

This line in your app.php, 'key' => env('APP_KEY', 'SomeRandomString'),, is saying that the key for your application can be found in your .env file on the line APP_KEY.

Basically it tells Laravel to look for the key in the .env file first and if there isn't one there then to use 'SomeRandomString'.

When you use the php artisan key:generate it will generate the new key to your .env file and not the app.php file.

As kotapeter said, your .env will be inside your root Laravel directory and may be hidden; xampp/htdocs/laravel/blog

Unfortunately, no. You will have to cast each value individually.

You can't use text as a background image, but you can use the :before or :after pseudo classes to place a text character where you want it, without having to add all kinds of messy extra mark-up.

Be sure to set position:relative on your actual text wrapper for the positioning to work.

.mytextwithicon {
    position:relative;
}    
.mytextwithicon:before {
    content: "\25AE";  /* this is your text. You can also use UTF-8 character codes as I do here */
    font-family: FontAwesome;
    left:-5px;
    position:absolute;
    top:0;
 }

EDIT:

Font Awesome v5 uses other font names than older versions:

• For FontAwesome v5, Free Version, use: font-family: "Font Awesome 5 Free"
• For FontAwesome v5, Pro Version, use: font-family: "Font Awesome 5 Pro"

Note that you should set the same font-weight property, too (seems to be 900).

Another way to find the font name is to right click on a sample font awesome icon on your page and get the font name (same way the utf-8 icon code can be found, but note that you can find it out on :before).

You have a bad table design. You can't autoincrement a string, that doesn't make any sense. You have basically two options:

1.) change type of ID to int instead of string
2.) not recommended!!! - handle autoincrement by yourself. You first need to get the latest value from the database, parse it to the integer, increment it and attach it to the entity as a string again. VERY BAD idea

First option requires to change every table that has a reference to this table, BUT it's worth it.

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

For chat applications or any other application that is in constant conversation with the server, WebSockets are the best option. However, you can only use WebSockets with a server that supports them, so that may limit your ability to use them if you cannot install the required libraries. In which case, you would need to use Long Polling to obtain similar functionality.

By creating a custom JavaScriptConverter you can map any name to any property. But it does require hand coding the map, which is less than ideal.

public class DataObjectJavaScriptConverter : JavaScriptConverter
{
    private static readonly Type[] _supportedTypes = new[]
    {
        typeof( DataObject )
    };

    public override IEnumerable<Type> SupportedTypes 
    { 
        get { return _supportedTypes; } 
    }

    public override object Deserialize( IDictionary<string, object> dictionary, 
                                        Type type, 
                                        JavaScriptSerializer serializer )
    {
        if( type == typeof( DataObject ) )
        {
            var obj = new DataObject();
            if( dictionary.ContainsKey( "user_id" ) )
                obj.UserId = serializer.ConvertToType<int>( 
                                           dictionary["user_id"] );
            if( dictionary.ContainsKey( "detail_level" ) )
                obj.DetailLevel = serializer.ConvertToType<DetailLevel>(
                                           dictionary["detail_level"] );

            return obj;
        }

        return null;
    }

    public override IDictionary<string, object> Serialize( 
            object obj, 
            JavaScriptSerializer serializer )
    {
        var dataObj = obj as DataObject;
        if( dataObj != null )
        {
            return new Dictionary<string,object>
            {
                {"user_id", dataObj.UserId },
                {"detail_level", dataObj.DetailLevel }
            }
        }
        return new Dictionary<string, object>();
    }
}

Then you can deserialize like so:

var serializer = new JavaScriptSerializer();
serialzer.RegisterConverters( new[]{ new DataObjectJavaScriptConverter() } );
var dataObj = serializer.Deserialize<DataObject>( json );

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

This should get you started:

set datafile separator ","
plot 'infile' using 0:1

include() needs a full file path, relative to the file system's root directory.

This should work:

 include_once("C:/xampp/htdocs/PoliticalForum/headerSite.php");

Other file extensions used include .cxx and .C (capital C). I believe Bjarne Stroustrup used .C originally. .cpp is the name of the C preprocessor so it's unfortunate that it was used for C++ as well.

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in this blog post.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.

- Epytext

Historically a javadoc like style was prevalent, so it was taken as a base for Epydoc (with the called Epytext format) to generate documentation.

Example:

"""
This is a javadoc style.

@param param1: this is a first param
@param param2: this is a second param
@return: this is a description of what is returned
@raise keyError: raises an exception
"""

- reST

Nowadays, the probably more prevalent format is the reStructuredText (reST) format that is used by Sphinx to generate documentation. Note: it is used by default in JetBrains PyCharm (type triple quotes after defining a method and hit enter). It is also used by default as output format in Pyment.

Example:

"""
This is a reST style.

:param param1: this is a first param
:param param2: this is a second param
:returns: this is a description of what is returned
:raises keyError: raises an exception
"""

- Google

Google has their own format that is often used. It also can be interpreted by Sphinx (ie. using Napoleon plugin).

Example:

"""
This is an example of Google style.

Args:
    param1: This is the first param.
    param2: This is a second param.

Returns:
    This is a description of what is returned.

Raises:
    KeyError: Raises an exception.
"""

Even more examples

- Numpydoc

Note that Numpy recommend to follow their own numpydoc based on Google format and usable by Sphinx.

"""
My numpydoc description of a kind
of very exhautive numpydoc format docstring.

Parameters
----------
first : array_like
    the 1st param name `first`
second :
    the 2nd param
third : {'value', 'other'}, optional
    the 3rd param, by default 'value'

Returns
-------
string
    a value in a string

Raises
------
KeyError
    when a key error
OtherError
    when an other error
"""

Converting/Generating

It is possible to use a tool like Pyment to automatically generate docstrings to a Python project not yet documented, or to convert existing docstrings (can be mixing several formats) from a format to an other one.

Note: The examples are taken from the Pyment documentation

SimpleTimer (Swift 3.1)

Why?

This is a simple timer class in swift that enables you to:

• Local scoped timer
• Chainable
• One liners
• Use regular callbacks

Usage:

SimpleTimer(interval: 3,repeats: true){print("tick")}.start()//Ticks every 3 secs

Code:

class SimpleTimer {/*<--was named Timer, but since swift 3, NSTimer is now Timer*/
    typealias Tick = ()->Void
    var timer:Timer?
    var interval:TimeInterval /*in seconds*/
    var repeats:Bool
    var tick:Tick

    init( interval:TimeInterval, repeats:Bool = false, onTick:@escaping Tick){
        self.interval = interval
        self.repeats = repeats
        self.tick = onTick
    }
    func start(){
        timer = Timer.scheduledTimer(timeInterval: interval, target: self, selector: #selector(update), userInfo: nil, repeats: true)//swift 3 upgrade
    }
    func stop(){
        if(timer != nil){timer!.invalidate()}
    }
    /**
     * This method must be in the public or scope
     */
    @objc func update() {
        tick()
    }
}

The Reason for Warning is your using Old ADT (Android development tools), so Update your ADT by following the procedures below

Procedure 1:

1. Inside Eclipse Click Help menu
2. Choose Check for Updates
3. It will show Required Updates in that window choose All options using Check box or else choose ADT Updated.

Procedure 2:

Click Help > Install New Software. In the Work with field, enter: https://dl-ssl.google.com/android/eclipse/ Select Developer Tools / Android Development Tools. Click Next and complete the wizard.

if name in ("Jesse", "jesse"):

would be the correct way to do it.

Although, if you want to use or, the statement would be

if name == 'Jesse' or name == 'jesse':

>>> ("Jesse" or "jesse")
'Jesse'

evaluates to 'Jesse', so you're essentially not testing for 'jesse' when you do if name == ("Jesse" or "jesse"), since it only tests for equality to 'Jesse' and does not test for 'jesse', as you observed.

DateValue(CStr(Now()))

That's the best I've found. If you have the date as a string already you can just do:

DateValue("12/04/2012 04:56:15")

or

DateValue(*DateStringHere*)

Hope this helps someone...

This command worked for me

find . -mtime -1 -print

I think 'input' simply works here the same way 'oninput' does in the DOM Level O Event Model.

Incidentally:

Just as silkfire commented it, I too googled for 'jQuery input event'. Thus I was led to here and astounded to learn that 'input' is an acceptable parameter to jquery's bind() command. In jQuery in Action (p. 102, 2008 ed.) 'input' is not mentionned as a possible event (against 20 others, from 'blur' to 'unload'). It is true that, on p. 92, the contrary could be surmised from rereading (i.e. from a reference to different string identifiers between Level 0 and Level 2 models). That is quite misleading.

For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png, and I put this in my css file...

div.example { background: url('example.png'); }

... then somehow it magically works. I figured this out by running the rake assets:precompile task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets. That's ironic, IMO...

In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.

Kind of frustrating there aren't better docs out there for this big of a change.

Just go through the below code.

SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);

smtpClient.Credentials = new System.Net.NetworkCredential("[email protected]", "myIDPassword");
// smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();

//Setting From , To and CC
mail.From = new MailAddress("info@MyWebsiteDomainName", "MyWeb Site");
mail.To.Add(new MailAddress("info@MyWebsiteDomainName"));
mail.CC.Add(new MailAddress("[email protected]"));

smtpClient.Send(mail);

That is so basic that I am wondering what book you are using to study? Try

data[1, "V1"]  # row first, quoted column name second, and case does matter

Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.

I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html

Tested out Warkst's third code snippet--worked great, except I changed it to be default input type instead of numeric:

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeDefault;
alertTextField.placeholder = @"Enter your name";
[alert show];

If you want to use enhanced loop, you can convert the string to charArray

for (char ch : exampleString.toCharArray()) {
  System.out.println(ch);
}

I found cascading it works great for multibrowser detection.

This code was used to change a fade to show/hide in ie 8 7 6.

$(document).ready(function(){
    if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 8.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 7.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         {if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 6.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { $('#shop').hover(function() {
        $(".glow").stop(true).fadeTo("400ms", 1);
    }, function() {
        $(".glow").stop(true).fadeTo("400ms", 0.2);});
         }
         }
         }
       });

Try adding the following to your eclipse.ini file:

-vm
C:\Program Files\Java\jdk1.7.0_01\bin\java.exe

You might also have to change the Dosgi.requiredJavaVersion to 1.7 in the same file.

android:inputMethod

is deprecated, instead use inputType :

 android:inputType="numberPassword"

If the dataset is called data, then all the rows meeting a condition where value of column 'pm2.5' > 300 can be received by -

data[data['pm2.5'] >300,]

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Here $users is a PDOStatement object over which you can iterate. The first iteration outputs all results, the second does nothing since you can only iterate over the result once. That's because the data is being streamed from the database and iterating over the result with foreach is essentially shorthand for:

while ($row = $users->fetch()) ...

Once you've completed that loop, you need to reset the cursor on the database side before you can loop over it again.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
$result = $users->fetch(PDO::FETCH_ASSOC);
foreach($result as $key => $value) {
    echo $key . "-" . $value . "<br/>";
}

Here all results are being output by the first loop. The call to fetch will return false, since you have already exhausted the result set (see above), so you get an error trying to loop over false.

In the last example you are simply fetching the first result row and are looping over it.

The cut command is designed for this exact situation. It will "cut" on any delimiter and then you can specify which chunks should be output.

For instance: echo "foo bar <foo> bla 1 2 3.4" | cut -d " " -f 6-7

Will result in output of: 2 3.4

-d sets the delimiter

-f selects the range of 'fields' to output, in this case, it's the 6th through 7th chunks of the original string. You can also specify the range as a list, such as 6,7.

Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a "way" of overloading.

def myfunc(a,b, *args, **kwargs):
   for ar in args:
      print ar
myfunc(a,b,c,d,e,f)

And it will print values of c,d,e,f

Similarly you could use the kwargs argument and then you could name your parameters.

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

And then kwargs would have a dictionary of all the parameters that are key valued after a,b

ad 1. It does not implement its methods.

ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap is an interface that extends Map. A client not interested in the sorting aspect can code against Map and handle all the instances of for example TreeMap, which implements SortedMap. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap interface.

In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.

A very common way to return multiple values in javascript is using an object literals, so something like:

const myFunction = () => {
  const firstName = "Alireza", 
        familyName = "Dezfoolian",
        age = 35;
  return { firstName, familyName, age};
}

and get the values like this:

myFunction().firstName; //Alireza
myFunction().familyName; //Dezfoolian
myFunction().age; //age

or even a shorter way:

const {firstName, familyName, age} = myFunction();

and get them individually like:

firstName; //Alireza
familyName; //Dezfoolian
age; //35

Just found this, it works for me and I personally find it easier to read.

This will set the actual index just like gnarf's answer number 3 option.

// sets selected index of a select box the actual index of 0 
$("select#elem").attr('selectedIndex', 0);

This didn't used to work but does now... see bug: http://dev.jquery.com/ticket/1474

Addendum

As recommended in the comments use :

$("select#elem").prop('selectedIndex', 0);

You just need to close the visual studio code and restart again. But to get the ng command work in vs code, you need to first compile the project with cmd in administrator mode.

I was also facing the same problem. But this method resolved it.

My solution - solved it for Angular 5 with Material View
The connection is through the

formArrayName="notification"

(change)="updateChkbxArray(n.id, $event.checked, 'notification')"

This way it can work for multiple checkboxes arrays in one form. Just set the name of the controls array to connect each time.

constructor(_x000D_
  private fb: FormBuilder,_x000D_
  private http: Http,_x000D_
  private codeTableService: CodeTablesService) {_x000D_
_x000D_
  this.codeTableService.getnotifications().subscribe(response => {_x000D_
      this.notifications = response;_x000D_
    })_x000D_
    ..._x000D_
}_x000D_
_x000D_
_x000D_
createForm() {_x000D_
  this.form = this.fb.group({_x000D_
    notification: this.fb.array([])..._x000D_
  });_x000D_
}_x000D_
_x000D_
ngOnInit() {_x000D_
  this.createForm();_x000D_
}_x000D_
_x000D_
updateChkbxArray(id, isChecked, key) {_x000D_
  const chkArray = < FormArray > this.form.get(key);_x000D_
  if (isChecked) {_x000D_
    chkArray.push(new FormControl(id));_x000D_
  } else {_x000D_
    let idx = chkArray.controls.findIndex(x => x.value == id);_x000D_
    chkArray.removeAt(idx);_x000D_
  }_x000D_
}

<div class="col-md-12">_x000D_
  <section class="checkbox-section text-center" *ngIf="notifications  && notifications.length > 0">_x000D_
    <label class="example-margin">Notifications to send:</label>_x000D_
    <p *ngFor="let n of notifications; let i = index" formArrayName="notification">_x000D_
      <mat-checkbox class="checkbox-margin" (change)="updateChkbxArray(n.id, $event.checked, 'notification')" value="n.id">{{n.description}}</mat-checkbox>_x000D_
    </p>_x000D_
  </section>_x000D_
</div>

At the end you are getting to save the form with array of original records id's to save/update.

Will be happy to have any remarks for improvement.

Resolved this issue by using http(s) when accessing the endpoint. The route I was accessing was not available over http. So I would say verify the protocols for which the route is available.

[ is a command (or a builtin in some shells). It must be separated by whitespace from the preceding statement:

Easy task using stringByReplacingOccurrencesOfString

I was facing this issue after i updated to Android-Studio 3.6 the only way that worked for me was downgrading project build.gradle setting by changing

from

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.0'
}

to

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0'
}

Either you can use CSV functions or PHPExcel

or you can try like below

<?php
$file="demo.xls";
$test="<table  ><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file");
echo $test;
?>

The header for .xlsx files is Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

First of all, %d is for a int

So %1.16lld makes no sense, because %d is an integer

That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.

What you want to use is the type double, for calculating pi and then using %f or %1.16f.

Having been recently bitten by the FP bug reading many wonderful accounts of how neatly the functional paradigm fits with Javascript

I replicate the code for completeness sake and suggest two ways this can be done functionally.

    var carBrands = [];

  var car1 = {name:'ford'};
  var car2 = {name:'lexus'};
  var car3 = {name:'maserati'};
  var car4 = {name:'ford'};
  var car5 = {name:'toyota'};

  carBrands.push(car1);
  carBrands.push(car2);
  carBrands.push(car3);
  carBrands.push(car4);

  // ES6 approach which uses the includes method (Chrome47+, Firefox43+)

  carBrands.includes(car1) // -> true
  carBrands.includes(car5) // -> false

If you need to support older browsers use the polyfill, it seems IE9+ and Edge do NOT support it. Located in polyfill section of MSDN page

Alternatively I would like to propose an updated answer to cdhowie

// ES2015 syntax
function containsObject(obj, list) {

    return list.some(function(elem) {
      return elem === obj
    })
}

// or ES6+ syntax with cool fat arrows
function containsObject(obj, list) {

    return list.some(elem => elem === obj)
}

This might be useful:

div {
    position: relative;
    width: 200px;
    height: 200px;
}
img {
    position: absolute;
    top: 0;
    bottom: 0;
    margin: auto;
}
.image {
    min-height: 50px
}

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

axs = axs.ravel()

for i in range(10):

    axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
    axs[i].set_title(str(250+i))

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).

If youtube-dl is a terminal program, you can use the subprocess module to access the data you want.

It is .shape:

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

Here is a side-by-side comparison of several application starters/generators and other technologies including MEAN.js, MEAN.io, and cleverstack. I keep adding alternatives as I find time and as that happens, the list of potentially provided benefits keeps growing too. Today it's up to around 1600. If anyone wants to help improve its accuracy or completeness, click the next link and do a questionnaire about something you know.

Compare app technologies project

From this database, the system generates reports like the following:

MeanJS vs MeanIO trade-off report

This can be done from the command line. This will create a column for your image with a NOT NULL property.

CREATE TABLE `test`.`pic` (
`idpic` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
`caption` VARCHAR(45) NOT NULL,
`img` LONGBLOB NOT NULL,
PRIMARY KEY(`idpic`)
)
TYPE = InnoDB; 

From here

In your example, I think that calling GC.Collect isn't the issue, but rather there is a design issue.

If you are going to wake up at intervals, (set times) then your program should be crafted for a single execution (perform the task once) and then terminate. Then, you set the program up as a scheduled task to run at the scheduled intervals.

This way, you don't have to concern yourself with calling GC.Collect, (which you should rarely if ever, have to do).

That being said, Rico Mariani has a great blog post on this subject, which can be found here:

http://blogs.msdn.com/ricom/archive/2004/11/29/271829.aspx

I would answer with slight modification with aforementioned answers and that is to write a prettified JSON file which human eyes can read better. For this, pass sort_keys as True and indent with 4 space characters and you are good to go. Also take care of ensuring that the ascii codes will not be written in your JSON file:

with open('data.txt', 'w') as outfile:
     json.dump(jsonData, outfile, sort_keys = True, indent = 4,
               ensure_ascii = False)

I found "display:flex" style is a good way to make these elements in same line. No matter what kind of element in the div. Especially if the input class is form-control,other solutions like bootstrap, inline-block will not work well.

Example:

<div style="display:flex; flex-direction: row; justify-content: center; align-items: center">
    <label for="Student">Name:</label>
    <input name="Student" />
</div>

More detail about display:flex:

flex-direction: row, column

justify-content: flex-end, center, space-between, space-around

align-items: stretch, flex-start, flex-end, center

I usually do docker rm -f $(docker ps -a -q) and docker system prune to purge all dangling containers.

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

This nodejs code just do that , as @Felix Yan mentioned former way seems to work just fine , i had some issues with other snipets hope this helps.

This will rename column "oldColumnName" to be "newColumnName" of table "documents"

var MongoClient = require('mongodb').MongoClient
  , assert = require('assert');

// Connection URL
//var url = 'mongodb://localhost:27017/myproject';
var url = 'mongodb://myuser:[email protected]:portNumber/databasename';

// Use connect method to connect to the server
MongoClient.connect(url, function(err, db) {
  assert.equal(null, err);
  console.log("Connected successfully to server");

  renameDBColumn(db, function() {
    db.close();
  });

});

//
// This function should be used for renaming a field for all documents
//
var renameDBColumn = function(db, callback) {
  // Get the documents collection
  console.log("renaming database column of table documents");
  //use the former way:
  remap = function (x) {
    if (x.oldColumnName){
      db.collection('documents').update({_id:x._id}, {$set:{"newColumnName":x.oldColumnName}, $unset:{"oldColumnName":1}});
    }
  }

  db.collection('documents').find().forEach(remap);
  console.log("db table documents remap successfully!");
}

Though the question appears to be demanding plotting a histogram using matplotlib.hist() function, it can arguably be not done using the same as the latter part of the question demands to use the given probabilities as the y-values of bars and given names(strings) as the x-values.

I'm assuming a sample list of names corresponding to given probabilities to draw the plot. A simple bar plot serves the purpose here for the given problem. The following code can be used:

import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375, 
  0.373117033603708, 0.36813186813186816, 0.32517482517482516, 
  0.4175257731958763, 0.41025641025641024, 0.39408866995073893, 
  0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327, 
  0.35398230088495575]
names = ['name1', 'name2', 'name3', 'name4', 'name5', 'name6', 'name7', 'name8', 'name9',
'name10', 'name11', 'name12', 'name13'] #sample names
plt.bar(names, probability)
plt.xticks(names)
plt.yticks(probability) #This may be included or excluded as per need
plt.xlabel('Names')
plt.ylabel('Probability')

I encountered this issue while running an app on Java 1.6 while I have all three versions of Java 6,7,8 for different apps.I accessed the Navigator View and manually removed the unwanted facet from the facet.core.xml .Clean build and wallah!

<fixed facet="jst.java"/>

QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/

I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.

This is a gotcha in VB.NET. The Visual Basic result won't reinitialize the variable in this example:

For i as Integer = 1 to 100
    Dim j as Integer
    Console.WriteLine(j)
    j = i
Next

' Output: 0 1 2 3 4...

This will print 0 the first time (Visual Basic variables have default values when declared!) but i each time after that.

If you add a = 0, though, you get what you might expect:

For i as Integer = 1 to 100
    Dim j as Integer = 0
    Console.WriteLine(j)
    j = i
Next

'Output: 0 0 0 0 0...

EDIT

Disregard - you can't use ItemOf (that's what I get for typing before I test). I'd strikethrough the text if I could figure out how...or maybe I'll simply delete the answer, since it was ultimately wrong and useless.

END EDIT

You can use the ItemOf(string) property in the XmlAttributesCollection to see if the attribute exists. It returns null if it's not found.

foreach (XmlNode xNode in nodeListName)
{
    if (xNode.ParentNode.Attributes.ItemOf["split"] != null)
    {
         parentSplit = xNode.ParentNode.Attributes["split"].Value;
    }
}

XmlAttributeCollection.ItemOf Property (String)

I am using angular 4 and faced the same issue apply, all possible solution but finally, this solve my problem

export class AppRoutingModule {
constructor(private router: Router) {
    this.router.errorHandler = (error: any) => {
        this.router.navigate(['404']); // or redirect to default route
    }
  }
}

Hope this will help you.

I have used enum FragmentTags to define all my fragment classes.

TAG_FOR_FRAGMENT_A(A.class),
TAG_FOR_FRAGMENT_B(B.class),
TAG_FOR_FRAGMENT_C(C.class)

pass FragmentTags.TAG_FOR_FRAGMENT_A.name() as fragment tag.

and now on

@Override
public void onBackPressed(){
   FragmentManager fragmentManager = getFragmentManager();
   Fragment current
   = fragmentManager.findFragmentById(R.id.fragment_container);
    FragmentTags fragmentTag = FragmentTags.valueOf(current.getTag());

  switch(fragmentTag){
    case TAG_FOR_FRAGMENT_A:
        finish();
        break;
   case TAG_FOR_FRAGMENT_B:
        fragmentManager.popBackStack();
        break;
   case default: 
   break;
}

You can do typeOf(T), but I would double check your method and make sure your not violating single responsability here. This would be a code smell, and that's not to say it shouldn't be done but that you should be cautious.

The point of generics is being able to build type-agnostic algorthims were you don't care what the type is or as long as it fits within a certain set of criteria. Your implementation isn't very generic.

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

Here is the simplest way given

 <script type="text/javascript">

        $(document).ready(function () {
            $("#chk_selall").change("click", function () {

                if (this.checked)
                {
                    //do something
                }
                if (!this.checked)
                {
                    //do something

                }

            });

        });

    </script>

protected void TestSubmit_ServerClick(object sender, EventArgs e)
{
  using (StreamWriter _testData = new StreamWriter(Server.MapPath("~/data.txt"), true))
 {
  _testData.WriteLine(TextBox1.Text); // Write the file.
 }         
}

Server.MapPath takes a virtual path and returns an absolute one. "~" is used to resolve to the application root.

def main(argv):
    host = argv[0]
    type = argv[1]
    val = argv[2]

    ping = subprocess.Popen(['python ftp.py %s %s %s'%(host,type,val)],stdout = subprocess.PIPE,stderr = subprocess.PIPE,shell=True)
    out = ping.communicate()[0]
    output = str(out)
    print output

In Swift 4.1 and Xcode 9.4.1

The solution is

DispatchQueue.main.async(execute: {
    self.present(alert, animated: true)
})

If write like this i'm getting same error

let alert = UIAlertController(title: "title", message: "message", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .default, handler: { action in
    })
alert.addAction(defaultAction)

present(alert, animated: true, completion: nil) 

I'm getting same error

Presenting view controllers on detached view controllers is discouraged <MyAppName.ViewController: 0x7fa95560Z070>.

Complete solution is

let alert = UIAlertController(title: "title", message: "message", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .default, handler: { action in
     })
alert.addAction(defaultAction)
//Made Changes here    
DispatchQueue.main.async(execute: {
    self.present(alert, animated: true)
})

The easiest way to convert a byte array to a stream is using the MemoryStream class:

Stream stream = new MemoryStream(byteArray);

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

Iterators make your code more generic.
Every standard library container provides an iterator hence if you change your container class in future the loop wont be affected.

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

You can also use SET instead of DECLARE

SET @myvar := (SELECT somevalue INTO myvar FROM mytable WHERE uid=1);

SELECT myvar;

Hi first give an id to the select as

<select id=theid>
<option value="test">label </option>
</select>

then you can call the selected label like that:

jQuery('#theid option:selected').text()

I'm sure you have enough to go on by now, but I can't help but suggest using the k-means clustering method. k-means is an unsupervised clustering algorithm which will take you data (in any number of dimensions - I happen to do this in 3D) and arrange it into k clusters with distinct boundaries. It's nice here because you know exactly how many toes these canines (should) have.

Additionally, it's implemented in Scipy which is really nice (http://docs.scipy.org/doc/scipy/reference/cluster.vq.html).

Here's an example of what it can do to spatially resolve 3D clusters:

What you want to do is a bit different (2D and includes pressure values), but I still think you could give it a shot.

On https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest I found this snippet that uses internal js module:

async function sha256(message) {
    // encode as UTF-8
    const msgBuffer = new TextEncoder().encode(message);                    

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string                  
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

Note that crypto.subtle in only available on https or localhost - for example for your local development with python3 -m http.server you need to add this line to your /etc/hosts: 0.0.0.0 localhost

Reboot - and you can open localhost:8000 with working crypto.subtle.

Just one thing to add to this (although I do think you have already had your question answered by others). In the interests of extensibility (since we all know it will happen at some point) you may want to check out the Composite Pattern This is ideal for working with "Tree-Like Structures"..

Like I said, I know you are only expecting one sub-level, but this could really be useful for you if you later need to extend ^_^

In a generic sense an webservice IS a API over HTTP. They often utilize JSON or XML, but there are some other approaches as well.

You can have a integrated terminal inside Visual Studio using one of these extensions:

Use the map-function instead. It transforms the value inside the optional.

Like this:

private String getStringIfObjectIsPresent(Optional<Object> object) {
    return object.map(() -> {
        String result = "result";
        //some logic with result and return it
        return result;
    }).orElseThrow(MyCustomException::new);
}

random.sample(population, k)

It is used for randomly sampling a sample of length 'k' from a population. returns a 'k' length list of unique elements chosen from the population sequence or set

it returns a new list and leaves the original population unchanged and the resulting list is in selection order so that all sub-slices will also be valid random samples

I am putting up an example in which I am splitting a dataset randomly. It is basically a function in which you pass x_train(population) as an argument and return indices of 60% of the data as D_test.

import random

def randomly_select_70_percent_of_data_from_1_to_length(x_train):
    return random.sample(range(0, len(x_train)), int(0.6*len(x_train)))

Long story short, node draws from V8, which is internally single-threaded. There are ways to work around the constraints for CPU-intensive tasks.

At one point (0.7) the authors tried to introduce isolates as a way of implementing multiple threads of computation, but were ultimately removed: https://groups.google.com/forum/#!msg/nodejs/zLzuo292hX0/F7gqfUiKi2sJ

You do not embed the images in the bundle. They are called through the browser. So its;

var imgSrc = './image/image1.jpg';

return <img src={imgSrc} />

I think using dtype where there is a name row is confusing the routine. Try

CREATE TABLE dbo.OwnerType

insert into OwnerType (Name) values ('User');

I think that would be the most general way to represent what you want instead of using a flag.

For those who are interested, here is my implementation extending MBO's original answer (written against rails 4.2.4, ruby 2.1.5).

The console.log should be wrapped in a function , the "default" function for every class is its constructor so it should be declared there.

import { Component } from '@angular/core';
console.log("Hello1");

 @Component({
  selector: 'hello-console',
})
    export class App {
     s: string = "Hello2";
    constructor(){
     console.log(s); 
    }

}

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

This below code snippet for scala users :

Option 1 :

Below snippet you can add at the file level

import org.apache.log4j.{Level, Logger}
Logger.getLogger("org").setLevel(Level.WARN)

Option 2 :

Note : which will be applicable for all the application which is using spark session.

import org.apache.spark.sql.SparkSession

  private[this] implicit val spark = SparkSession.builder().master("local[*]").getOrCreate()

spark.sparkContext.setLogLevel("WARN")

Option 3 :

Note : This configuration should be added to your log4j.properties.. (could be like /etc/spark/conf/log4j.properties (where the spark installation is there) or your project folder level log4j.properties) since you are changing at module level. This will be applicable for all the application.

log4j.rootCategory=ERROR, console

IMHO, Option 1 is wise way since it can be switched off at file level.

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)

You should mention the library on the command line after the object files being compiled:

 gcc -Wstrict-prototypes -Wall -Wno-sign-compare -Wpointer-arith -Wdeclaration-after-statement -Wformat-security -Wswitch-enum -Wunused-parameter -Wstrict-aliasing -Wbad-function-cast -Wcast-align -Wstrict-prototypes -Wold-style-definition -Wmissing-prototypes -Wmissing-field-initializers -Wno-override-init \

Explanation: the linking is dependent on the order of modules. Symbols are first requested, and then linked in from a library that has them. So you have to specify modules that use libraries first, and libraries after them. Like this:

gcc x.o y.o z.o -la -lb -lc

Moreover, in case there's a circular dependency, you should specify the same library on the command line several times. So in case libb needs symbol from libc and libc needs symbol from libb, the command line should be:

gcc x.o y.o z.o -la -lb -lc -lb

Consider this CodeProject article/project: LINQ TO CSV.

It will enable you to create a custom class that is shaped like your .csv file's columns. You'd then consume the CSV and bind to your DataGridView.

Dim cc As new CsvContext()
Dim inputFileDescription As New CsvFileDescription() With { _
    .SeparatorChar = ","C, _
    .FirstLineHasColumnNames = True _
}

Dim products As IEnumerable(Of Product) = _
     cc.Read(Of Product)("products.csv", inputFileDescription)

' query from CSV, load into a new class of your own   
Dim productsByName = From p In products
    Select New CustomDisplayClass With _
       {.Name = p.Name, .SomeDate = p.SomeDate, .Price = p.Price}, _        
    Order By p.Name


myDataGridView1.DataSource = products
myDataGridView1.DataBind()

Variable names should be known at compile time. If you intend to populate those names dynamically at runtime you could use a List<T>

 var variables = List<Variable>();
 variables.Add(new Variable { Name = inputStr1 });
 variables.Add(new Variable { Name = inputStr2 });

here input string maybe any text or any list

One option you could consider is using CSS variables. The idea is that you set the property you want to change to a CSS variable. Then, within your JS, change that variable's value.

See example below

function changeColor(newColor) {
  document.documentElement.style.setProperty("--anchor-hover-color", newColor);
  // ^^^^^^^^^^^-- select the root 
}

:root {
  --anchor-hover-color: red;
}

a:hover { 
  color: var(--anchor-hover-color); 
}

<a href="#">Hover over me</a>

<button onclick="changeColor('lime')">Change to lime</button>
<button onclick="changeColor('red')">Change to red</button>

// Get pixel data
var imageData = context.getImageData(x, y, width, height);

// Color at (x,y) position
var color = [];
color['red'] = imageData.data[((y*(imageData.width*4)) + (x*4)) + 0];
color['green'] = imageData.data[((y*(imageData.width*4)) + (x*4)) + 1];
color['blue'] = imageData.data[((y*(imageData.width*4)) + (x*4)) + 2];
color['alpha'] = imageData.data[((y*(imageData.width*4)) + (x*4)) + 3];

Use a O/R framework such as hibernate

The output of the error, is because you call an index of the Array that does not exist, for example

$arr = Array(1,2,3);
echo $arr[3]; 
// Error PHP Notice:  Undefined offset: 1 pointer 3 does not exist, the array only has 3 elements but starts at 0 to 2, not 3!

In production site this seems suitable:

<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="www.mysite.com" />
<allow-access-from domain="mysite.com" />
</cross-domain-policy>

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

You can make it wait using $RANDOM, a default random number generator. In the below I am using 240 seconds. Hope that helps @

> WAIT_FOR_SECONDS=`/usr/bin/expr $RANDOM % 240` /bin/sleep
> $WAIT_FOR_SECONDS

I guess the problem is that you need to start a separate thread for each connection and call serverSocket.accept() in a loop to accept more than one connection.

It is not a problem to have more than one connection on the same port.

When you use addEventListener, this will be bound automatically. So if you want a reference to the element on which the event handler is installed, just use this from within your function:

productLineSelect.addEventListener('change',getSelection,false);

function getSelection(){
    var value = sel.options[this.selectedIndex].value;
    alert(value);
}

If you want to pass in some other argument from the context where you call addEventListener, you can use a closure, like this:

productLineSelect.addEventListener('change', function(){ 
    // pass in `this` (the element), and someOtherVar
    getSelection(this, someOtherVar); 
},false);

function getSelection(sel, someOtherVar){
    var value = sel.options[sel.selectedIndex].value;
    alert(value);
    alert(someOtherVar);
}

Ugly? I disagree. The only other way (I personally think this is "uglier"):

var obj = child as IContainer;
if(obj == null)
{
   //child "aint" IContainer
}

Your problem is that you are NOT testing the length of the array until it is too late.

But I just want to point out that the way to solve this problem is to READ THE STACK TRACE.

The exception message will clearly tell you are trying to create an array with length -1, and the trace will tell you exactly which line of your code is doing this. The rest is simple logic ... working back to why the length you are using is -1.

Let me explain a little more by my example.

Task: correct info, where abiturients (students about to leave secondary school) have submitted applications to university earlier, than they got school certificates (yes, they got certificates earlier, than they were issued (by certificate date specified). So, we will increase application submit date to fit certificate issue date.

Thus. next MySQL-like statement:

UPDATE applications a
JOIN (
    SELECT ap.id, ab.certificate_issued_at
    FROM abiturients ab
    JOIN applications ap 
    ON ab.id = ap.abiturient_id 
    WHERE ap.documents_taken_at::date < ab.certificate_issued_at
) b
ON a.id = b.id
SET a.documents_taken_at = b.certificate_issued_at;

Becomes PostgreSQL-like in such a way

UPDATE applications a
SET documents_taken_at = b.certificate_issued_at         -- we can reference joined table here
FROM abiturients b                                       -- joined table
WHERE 
    a.abiturient_id = b.id AND                           -- JOIN ON clause
    a.documents_taken_at::date < b.certificate_issued_at -- Subquery WHERE

As you can see, original subquery JOIN's ON clause have become one of WHERE conditions, which is conjucted by AND with others, which have been moved from subquery with no changes. And there is no more need to JOIN table with itself (as it was in subquery).

in this link i mentioned before on the comment, read this part :

A "fetch" join allows associations or collections of values to be initialized along with their parent objects using a single select. This is particularly useful in the case of a collection. It effectively overrides the outer join and lazy declarations of the mapping file for associations and collections.

this "JOIN FETCH" will have it's effect if you have (fetch = FetchType.LAZY) property for a collection inside entity(example bellow).

And it is only effect the method of "when the query should happen". And you must also know this:

hibernate have two orthogonal notions : when is the association fetched and how is it fetched. It is important that you do not confuse them. We use fetch to tune performance. We can use lazy to define a contract for what data is always available in any detached instance of a particular class.

when is the association fetched --> your "FETCH" type

how is it fetched --> Join/select/Subselect/Batch

In your case, FETCH will only have it's effect if you have department as a set inside Employee, something like this in the entity:

@OneToMany(fetch = FetchType.LAZY)
private Set<Department> department;

when you use

FROM Employee emp
JOIN FETCH emp.department dep

you will get emp and emp.dep. when you didnt use fetch you can still get emp.dep but hibernate will processing another select to the database to get that set of department.

so its just a matter of performance tuning, about you want to get all result(you need it or not) in a single query(eager fetching), or you want to query it latter when you need it(lazy fetching).

Use eager fetching when you need to get small data with one select(one big query). Or use lazy fetching to query what you need latter(many smaller query).

use fetch when :

• no large unneeded collection/set inside that entity you about to get

• communication from application server to database server too far and need long time

• you may need that collection latter when you don't have the access to it(outside of the transactional method/class)

Use RC addressing. So, if I want the background color of Col B to depend upon the value in Col C and apply that from Rows 2 though 20:

Steps:

1. Select R2C2 to R20C2

2. Click on Conditional Formatting

3. Select "Use a formula to determine what cells to format"

4. Type in the formula: =RC[1] > 25

5. Create the formatting you want (i.e. background color "yellow")

6. Applies to: Make sure it says: =R2C2:R20C2

** Note that the "magic" takes place in step 4 ... using RC addressing to look at the value one column to the right of the cell being formatted. In this example, I am checking to see if the value of the cell one column to the right of the cell being formatting contains a value greater than 25 (note that you can put pretty much any formula here that returns a T/F value)

The upside-down A symbol is the universal quantifier from predicate logic. (Also see the more complete discussion of the first-order predicate calculus.) As others noted, it means that the stated assertions holds "for all instances" of the given variable (here, s). You'll soon run into its sibling, the backwards capital E, which is the existential quantifier, meaning "there exists at least one" of the given variable conforming to the related assertion.

If you're interested in logic, you might enjoy the book Logic and Databases: The Roots of Relational Theory by C.J. Date. There are several chapters covering these quantifiers and their logical implications. You don't have to be working with databases to benefit from this book's coverage of logic.

For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.

The extern declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern in a header file like:

extern struct a myAValue;

Then, in one source file, define the actual variable:

struct a myAValue;

If you forget to do this or accidentally define it in two source files, the linker will let you know about this.

I had the same problem but finally I found the way.

Here is the walk through:

1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)

2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.

3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:

:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}

NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...

NOTE: You can see, the video codec is MP4V which is supported by android.

4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:

mVideoView = (VideoView) findViewById(R.id.surface_view);

mVideoView.setVideoPath("rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/");
mVideoView.setMediaController(new MediaController(this));

5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...

Question: Anybody know how to reduce buffering time and play video almost live ?

If you are trying to parse apart a human name in PHP, I recommend Keith Beckman's nameparse.php script.

Copy in case site goes down:

Bugs:   If one of the words in the middle name is Ben (or St., for that matter),
        or any other possible last-name prefix, the name MUST be entered in
        last-name-first format. If the last-name parsing routines get ahold
        of any prefix, they tie up the rest of the name up to the suffix. i.e.:

        William Ben Carey   would yield 'Ben Carey' as the last name, while,
        Carey, William Ben  would yield 'Carey' as last and 'Ben' as middle.

        This is a problem inherent in the prefix-parsing routines algorithm,
        and probably will not be fixed. It's not my fault that there's some
        odd overlap between various languages. Just don't name your kids
        'Something Ben Something', and you should be alright.

Took the code above and fixed because it throws Internal Server Error 500. There are some problems with \r\n badly positioned and spaces etc. Applied the refactoring with memory stream, writing directly to the request stream. Here is the result:

    public static void HttpUploadFile(string url, string file, string paramName, string contentType, NameValueCollection nvc) {
        log.Debug(string.Format("Uploading {0} to {1}", file, url));
        string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");
        byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");

        HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url);
        wr.ContentType = "multipart/form-data; boundary=" + boundary;
        wr.Method = "POST";
        wr.KeepAlive = true;
        wr.Credentials = System.Net.CredentialCache.DefaultCredentials;

        Stream rs = wr.GetRequestStream();

        string formdataTemplate = "Content-Disposition: form-data; name=\"{0}\"\r\n\r\n{1}";
        foreach (string key in nvc.Keys)
        {
            rs.Write(boundarybytes, 0, boundarybytes.Length);
            string formitem = string.Format(formdataTemplate, key, nvc[key]);
            byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
            rs.Write(formitembytes, 0, formitembytes.Length);
        }
        rs.Write(boundarybytes, 0, boundarybytes.Length);

        string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n";
        string header = string.Format(headerTemplate, paramName, file, contentType);
        byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
        rs.Write(headerbytes, 0, headerbytes.Length);

        FileStream fileStream = new FileStream(file, FileMode.Open, FileAccess.Read);
        byte[] buffer = new byte[4096];
        int bytesRead = 0;
        while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0) {
            rs.Write(buffer, 0, bytesRead);
        }
        fileStream.Close();

        byte[] trailer = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "--\r\n");
        rs.Write(trailer, 0, trailer.Length);
        rs.Close();

        WebResponse wresp = null;
        try {
            wresp = wr.GetResponse();
            Stream stream2 = wresp.GetResponseStream();
            StreamReader reader2 = new StreamReader(stream2);
            log.Debug(string.Format("File uploaded, server response is: {0}", reader2.ReadToEnd()));
        } catch(Exception ex) {
            log.Error("Error uploading file", ex);
            if(wresp != null) {
                wresp.Close();
                wresp = null;
            }
        } finally {
            wr = null;
        }
    }

and sample usage:

    NameValueCollection nvc = new NameValueCollection();
    nvc.Add("id", "TTR");
    nvc.Add("btn-submit-photo", "Upload");
    HttpUploadFile("http://your.server.com/upload", 
         @"C:\test\test.jpg", "file", "image/jpeg", nvc);

It could be extended to handle multiple files or just call it multiple times for each file. However it suits your needs.

I've tried many of the previous answers, really nothing works for me but this solution did:

https://getbootstrap.com/docs/3.3/javascript/#dismiss-on-next-click

They recommend to use anchor tag not button and take care of role="button" + data-trigger="focus" + tabindex="0" attributes.

Ex:

<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" 
data-trigger="focus" title="Dismissible popover" data-content="amazing content">
Dismissible popover</a>

Try this:

par(adj = 0)
plot(1, 1, main = "Title")

or equivalent:

plot(1, 1, main = "Title", adj = 0)

adj = 0 produces left-justified text, 0.5 (the default) centered text and 1 right-justified text. Any value in [0, 1] is allowed.

However, the issue is that this will also change the position of the label of the x-axis and y-axis.

If you find by alphabet in plist, it should be "Application supports iTunes file sharing".

If the blob is instantiated with data from an F4M manifest (check the Network Tab in Chrome's Developer Tools), you can download the video file using the php script posted here: https://n1njahacks.wordpress.com/2015/01/29/how-to-save-hds-flash-streams-from-any-web-page/

By putting:

  if ($manifest == '')
    $manifest = $_GET['manifest'];

before:

  if ($manifest)

you could even run it on a webserver, using requests with the query string: ?manifest=[manifest url].

Note that you'll probably want to use an FTP client to retrieve the downloaded video file and clean up after the script (it leaves all the downloaded video parts).

An Asynchronous TryGet Pattern:

For synchronous methods, I believe @Johann Gerell's answer is the pattern to use in all cases.

However the TryGet pattern with the out parameter does not work with Async methods.

With C# 7's Tuple Literals you can now do this:

async Task<(bool success, SomeObject o)> TryGetSomeObjectByIdAsync(Int32 id)
{
    if (InternalIdExists(id))
    {
        o = await InternalGetSomeObjectAsync(id);

        return (true, o);
    }
    else
    {
        return (false, default(SomeObject));
    }
}

if you are trying to add a general note to the overall object (query or table etc..)

Access 2016 go to navigation pane, highlight object, right click, select object / table properties, add a note in the description window i.e. inventory "table last last updated 05/31/17"

Another option is to use GNU seq and remove all numbers and newlines it generates:

seq -f'#%.0f' 100 | tr -d '\n0123456789'

This command prints the # character 100 times.

Any API should check the validity of the every parameter of any public method before executing it:

void setPercentage(int pct, AnObject object) {
    if( pct < 0 || pct > 100) {
        throw new IllegalArgumentException("pct has an invalid value");
    }
    if (object == null) {
        throw new IllegalArgumentException("object is null");
    }
}

They represent 99.9% of the times errors in the application because it is asking for impossible operations so in the end they are bugs that should crash the application (so it is a non recoverable error).

In this case and following the approach of fail fast you should let the application finish to avoid corrupting the application state.

Fetch does not use cookie by default. To enable cookie, do this:

fetch(url, {
  credentials: "same-origin"
}).then(...).catch(...);

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

in my case it was not related to the path or filename. If filemtime(), fileatime() or filectime() don't work, try stat().

$filedate = date_create(date("Y-m-d", filectime($file)));

becomes

$stat = stat($directory.$file);
$filedate = date_create(date("Y-m-d", $stat['ctime']));

that worked for me.

Complete snippet for deleting files by number of days:

$directory = $_SERVER['DOCUMENT_ROOT'].'/directory/';
$files = array_slice(scandir($directory), 2);
foreach($files as $file)
{
    $extension      = substr($file, -3, 3); 
    if ($extension == 'jpg') // in case you only want specific files deleted
    {
        $stat = stat($directory.$file);
        $filedate = date_create(date("Y-m-d", $stat['ctime']));
        $today = date_create(date("Y-m-d"));
        $days = date_diff($filedate, $today, true);
        if ($days->days > 1) 
        { 
            unlink($directory.$file);
        }
    } 
}

I feel that the overall answer does not handle if the dates 'wrap' around a year. This would be useful in understanding proximity to a date being accurate by day of year. In order to do these row operations, I did the following. (I had this used in a business setting in renewing customer subscriptions).

def get_date_difference(row, x, y):
    try:
        # Calcuating the smallest date difference between the start and the close date
        # There's some tricky logic in here to calculate for determining date difference
        # the other way around (Dec -> Jan is 1 month rather than 11)

        sub_start_date = int(row[x].strftime('%j')) # day of year (1-366)
        close_date = int(row[y].strftime('%j')) # day of year (1-366)

        later_date_of_year = max(sub_start_date, close_date) 
        earlier_date_of_year = min(sub_start_date, close_date)
        days_diff = later_date_of_year - earlier_date_of_year

# Calculates the difference going across the next year (December -> Jan)
        days_diff_reversed = (365 - later_date_of_year) + earlier_date_of_year
        return min(days_diff, days_diff_reversed)

    except ValueError:
        return None

Then the function could be:

dfAC_Renew['date_difference'] = dfAC_Renew.apply(get_date_difference, x = 'customer_since_date', y = 'renewal_date', axis = 1)

Any unit test you could create by just pressing a button would not be worth anything. How is the tool to know what parameters to pass your method and what to expect back? Unless I'm misunderstanding your expectations.

Close to that is something like FitNesse, where you can set up tests, then separately you set up a wiki page with your test data, and it runs the tests with that data, publishing the results as red/greens.

If you would be happy to make test writing much faster, I would suggest Mockito, a mocking framework that lets you very easily mock the classes around the one you're testing, so there's less setup/teardown, and you know you're really testing that one class instead of a dependent of it.

Check out the addressable gem - a popular replacement for Ruby's URI module that makes query parsing easy:

require "addressable/uri"
uri = Addressable::URI.parse("http://www.example.com/something?param1=value1&param2=value2&param3=value3")
uri.query_values['param1']
=> 'value1'

(It also apparently handles param encoding/decoding, unlike URI)

Depending on what you're doing you might like to take a look at GMP (gmplib.org) which is a high-performance multi-precision library. To use it in Java you need JNI wrappers around the binary library.

See some of the Alioth Shootout code for an example of using it instead of BigInteger to calculate Pi to an arbitrary number of digits.

https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/pidigits-java-2.html

Here it worked on Mac OS X.

It includes the example of a BSD date, how to increment and decrement the date also:

for ((i=28; i>=6 ; i--));
do
    dat=`date -v-${i}d -j "+%Y%m%d"` 
    echo $dat
done

^[ _]*[A-Z0-9][A-Z0-9 _]*$

You can optionally have some spaces or underscores up front, then you need one letter or number, and then an arbitrary number of numbers, letters, spaces or underscores after that.

Something that contains only spaces and underscores will fail the [A-Z0-9] portion.

Many thanks for the information about using the QueryDefs collection! I have been wondering about this for a while.

I did it a different way, without using VBA, by using a table containing the query parameters.

E.g:

SELECT a_table.a_field 
FROM QueryParameters, a_table 
WHERE a_table.a_field BETWEEN QueryParameters.a_field_min 
AND QueryParameters.a_field_max

Where QueryParameters is a table with two fields, a_field_min and a_field_max

It can even be used with GROUP BY, if you include the query parameter fields in the GROUP BY clause, and the FIRST operator on the parameter fields in the HAVING clause.

I faced this same issue when I needed to load location data that I had serialized into the database from the google places API. Generally I would want the whole thing so it works with maps but I didn't want to have to specify all of the fields every time.

I was working in Ruby so I can't give you the PHP implementation but the principle should be the same.

I defined a custom scalar type called JSON which just returns a literal JSON object.

The ruby implementation was like so (using graphql-ruby)

module Graph
  module Types
    JsonType = GraphQL::ScalarType.define do
      name "JSON"
      coerce_input -> (x) { x }
      coerce_result -> (x) { x }
    end
  end
end

Then I used it for our objects like so

field :location, Types::JsonType

I would use this very sparingly though, using it only where you know you always need the whole JSON object (as I did in my case). Otherwise it is defeating the object of GraphQL more generally speaking.

OK, for me that is the way it worked (I am using Python 2.7):

a = __import__('file_to_import', globals(), locals(), ['*'], -1)
b = a.MyClass()

Then, b is an instance of class 'MyClass'

I was facing the Same Error.

Solution: The name of the variable in the View through which we are passing value to Controller should Match the Name of Variable on Controller Side.

.csHtml (View) :

@Html.ActionLink("Edit", "Edit" , new { id=item.EmployeeId })

.cs (Controller Method):

 [HttpGet]
            public ActionResult Edit(int id)
            {
                EmployeeContext employeeContext = new EmployeeContext();
                Employee employee = employeeContext.Employees.Where(emp => emp.EmployeeId == id).First();
                return View(employee);
            }

You can use either,

int i = Convert.ToInt32(TextBoxD1.Text);

or

int i = int.Parse(TextBoxD1.Text);

I managed to work out the answer by reading the manual :)

This extract from the MSDN

The code example avoids a deadlock condition by calling p.StandardOutput.ReadToEnd before p.WaitForExit. A deadlock condition can result if the parent process calls p.WaitForExit before p.StandardOutput.ReadToEnd and the child process writes enough text to fill the redirected stream. The parent process would wait indefinitely for the child process to exit. The child process would wait indefinitely for the parent to read from the full StandardOutput stream.

There is a similar issue when you read all text from both the standard output and standard error streams. For example, the following C# code performs a read operation on both streams.

Turns the code into this;

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "sqlplus";
p.StartInfo.Arguments = string.Format("xxx/xxx@{0} @{1}", in_database, s);

bool started = p.Start();
// important ... read stream input before waiting for exit.
// this avoids deadlock.
string output = p.StandardOutput.ReadToEnd();

p.WaitForExit();

Console.WriteLine(output);

if (p.ExitCode != 0)
{
    Console.WriteLine( string.Format("*** Failed : {0} - {1}",s,p.ExitCode));
    break;
}

Which now exits correctly.

You need convert to number type:

(+Low).toFixed(2)

private void Form1_Load(object sender, EventArgs e)

Expanding on Dejw's answer (edit2):

File.open(filename,'w'){ |f|
  uri = URI.parse(url)
  Net::HTTP.start(uri.host,uri.port){ |http| 
    http.request_get(uri.path){ |res| 
      res.read_body{ |seg|
        f << seg
#hack -- adjust to suit:
        sleep 0.005 
      }
    }
  }
}

where filename and url are strings.

The sleep command is a hack that can dramatically reduce CPU usage when the network is the limiting factor. Net::HTTP doesn't wait for the buffer (16kB in v1.9.2) to fill before yielding, so the CPU busies itself moving small chunks around. Sleeping for a moment gives the buffer a chance to fill between writes, and CPU usage is comparable to a curl solution, 4-5x difference in my application. A more robust solution might examine progress of f.pos and adjust the timeout to target, say, 95% of the buffer size -- in fact that's how I got the 0.005 number in my example.

Sorry, but I don't know a more elegant way of having Ruby wait for the buffer to fill.

Edit:

This is a version that automatically adjusts itself to keep the buffer just at or below capacity. It's an inelegant solution, but it seems to be just as fast, and to use as little CPU time, as it's calling out to curl.

It works in three stages. A brief learning period with a deliberately long sleep time establishes the size of a full buffer. The drop period reduces the sleep time quickly with each iteration, by multiplying it by a larger factor, until it finds an under-filled buffer. Then, during the normal period, it adjusts up and down by a smaller factor.

My Ruby's a little rusty, so I'm sure this can be improved upon. First of all, there's no error handling. Also, maybe it could be separated into an object, away from the downloading itself, so that you'd just call autosleep.sleep(f.pos) in your loop? Even better, Net::HTTP could be changed to wait for a full buffer before yielding :-)

def http_to_file(filename,url,opt={})
  opt = {
    :init_pause => 0.1,    #start by waiting this long each time
                           # it's deliberately long so we can see 
                           # what a full buffer looks like
    :learn_period => 0.3,  #keep the initial pause for at least this many seconds
    :drop => 1.5,          #fast reducing factor to find roughly optimized pause time
    :adjust => 1.05        #during the normal period, adjust up or down by this factor
  }.merge(opt)
  pause = opt[:init_pause]
  learn = 1 + (opt[:learn_period]/pause).to_i
  drop_period = true
  delta = 0
  max_delta = 0
  last_pos = 0
  File.open(filename,'w'){ |f|
    uri = URI.parse(url)
    Net::HTTP.start(uri.host,uri.port){ |http|
      http.request_get(uri.path){ |res|
        res.read_body{ |seg|
          f << seg
          delta = f.pos - last_pos
          last_pos += delta
          if delta > max_delta then max_delta = delta end
          if learn <= 0 then
            learn -= 1
          elsif delta == max_delta then
            if drop_period then
              pause /= opt[:drop_factor]
            else
              pause /= opt[:adjust]
            end
          elsif delta < max_delta then
            drop_period = false
            pause *= opt[:adjust]
          end
          sleep(pause)
        }
      }
    }
  }
end

This One Method For Published Solution To Show SpeciFic Page on startup.

Here Is the Route Example to Redirect to Specific Page...

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            namespaces: new[] { "YourSolutionName.Controllers" }
        );
    }
}

By Default Home Controllers Index method is executed when application is started, Here You Can Define yours.

Note : I am Using Visual Studio 2013 and "YourSolutionName" is to changed to your project Name..

Think about somebody doing help(yourmodule) at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help in terms of amount of information). So if you have in x.py:

"""This module does blah blah."""

class Blah(object):
  """This class does blah blah."""

then:

>>> import x; help(x)

shows:

Help on module x:

NAME
    x - This module does blah blah.

FILE
    /tmp/x.py

CLASSES
    __builtin__.object
        Blah

    class Blah(__builtin__.object)
     |  This class does blah blah.
     |  
     |  Data and other attributes defined here:
     |  
     |  __dict__ = <dictproxy object>
     |      dictionary for instance variables (if defined)
     |  
     |  __weakref__ = <attribute '__weakref__' of 'Blah' objects>
     |      list of weak references to the object (if defined)

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).

I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.

You don't need regex for this

>>> s = "Username: How are you today?"

You can use the split method to split the string on the ':' character

>>> s.split(':')
['Username', ' How are you today?']

And slice out element [0] to get the first part of the string

>>> s.split(':')[0]
'Username'
