There may be a valid reason why you want to do this, but generating this kind of XML is generally best avoided. Why? Because it means that the XML elements of your map are dependent on the runtime contents of your map. And since XML is usually used as an external interface or interface layer this is not desirable. Let me explain.

The Xml Schema (xsd) defines the interface contract of your XML documents. In addition to being able to generate code from the XSD, JAXB can also generate the XML schema for you from the code. This allows you to restrict the data exchanged over the interface to the pre-agreed structures defined in the XSD.

In the default case for a Map<String, String>, the generated XSD will restrict the map element to contain multiple entry elements each of which must contain one xs:string key and one xs:string value. That's a pretty clear interface contract.

What you describe is that you want the xml map to contain elements whose name will be determined by the content of the map at runtime. Then the generated XSD can only specify that the map must contain a list of elements whose type is unknown at compile time. This is something that you should generally avoid when defining an interface contract.

To achieve a strict contract in this case, you should use an enumerated type as the key of the map instead of a String. E.g.

public enum KeyType {
 KEY, KEY2;
}

@XmlJavaTypeAdapter(MapAdapter.class)
Map<KeyType , String> mapProperty;

That way the keys which you want to become elements in XML are known at compile time so JAXB should be able to generate a schema that would restrict the elements of map to elements using one of the predefined keys KEY or KEY2.

On the other hand, if you wish to simplify the default generated structure

<map>
    <entry>
        <key>KEY</key>
        <value>VALUE</value>
    </entry>
    <entry>
        <key>KEY2</key>
        <value>VALUE2</value>
    </entry>
</map>

To something simpler like this

<map>
    <item key="KEY" value="VALUE"/>
    <item key="KEY2" value="VALUE2"/>
</map>

You can use a MapAdapter that converts the Map to an array of MapElements as follows:

class MapElements {
    @XmlAttribute
    public String key;
    @XmlAttribute
    public String value;

    private MapElements() {
    } //Required by JAXB

    public MapElements(String key, String value) {
        this.key = key;
        this.value = value;
    }
}


public class MapAdapter extends XmlAdapter<MapElements[], Map<String, String>> {
    public MapAdapter() {
    }

    public MapElements[] marshal(Map<String, String> arg0) throws Exception {
        MapElements[] mapElements = new MapElements[arg0.size()];
        int i = 0;
        for (Map.Entry<String, String> entry : arg0.entrySet())
            mapElements[i++] = new MapElements(entry.getKey(), entry.getValue());

        return mapElements;
    }

    public Map<String, String> unmarshal(MapElements[] arg0) throws Exception {
        Map<String, String> r = new TreeMap<String, String>();
        for (MapElements mapelement : arg0)
            r.put(mapelement.key, mapelement.value);
        return r;
    }
}

If you are looking for an authentication framework for Connect or Express, Passport is worth investigating: https://github.com/jaredhanson/passport

(Disclosure: I'm the developer of Passport)

I developed Passport after investigating both connect-auth and everyauth. While they are both great modules, they didn't suit my needs. I wanted something that was more light-weight and unobtrusive.

Passport is broken down into separate modules, so you can choose to use only what you need (OAuth, only if necessary). Passport also does not mount any routes in your application, giving you the flexibility to decide when and where you want authentication, and hooks to control what happens when authentication succeeds or fails.

For example, here is the two-step process to setup form-based (username and password) authentication:

passport.use(new LocalStrategy(
  function(username, password, done) {
    // Find the user from your DB (MongoDB, CouchDB, other...)
    User.findOne({ username: username, password: password }, function (err, user) {
      done(err, user);
    });
  }
));

app.post('/login', 
  passport.authenticate('local', { failureRedirect: '/login' }),
  function(req, res) {
    // Authentication successful. Redirect home.
    res.redirect('/');
  });

Additional strategies are available for authentication via Facebook, Twitter, etc. Custom strategies can be plugged-in, if necessary.

Change the key of the component.

<Component key="1" />

<Component key="2" />

Component will be unmounted and a new instance of Component will be mounted since the key has changed.

edit: Documented on You Probably Don't Need Derived State:

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

You can add header "Content-Type: text/html; charset=UTF-8" to your message body.

$headers = "Content-Type: text/html; charset=UTF-8";

If you use native mail() function $headers array will be the 4th parameter mail($to, $subject, $message, $headers)

If you user PEAR Mail::factory() code will be:

$smtp = Mail::factory('smtp', $params);

$mail = $smtp->send($to, $headers, $body);

I recently had this issue and the clean/build etc. didn't resolve it. I guessed I had an issue somewhere but wasn't sure where to look to find it (was it in the manifest, resource xml files etc?).

When something is wrong, you can find out what it is by doing a code analysis run.

From the menu at the top choose:

Analyze -> Inspect code, scan the whole project using the 'Default' profile.

Your inspection results will contain an element called 'Android'. In here you will get a list of anything that is causing issues in your resources and manifest file. The errors will open up the generated xml files from your build which will show any errors in red.

My exact issue was caused because I was using flavour based manifest files and I copied some permissions inside the <application> tag in the flavour by accident.

UPDATE: I did have an issue after where Android Studio still showed the error after the fix, even though I could now build and run perfectly fine while the error was still there. (I am running a canary build so putting it down to that for now)

Since the glyphicons image is a sprite, you really can't do that: fundamentally what you want is to limit the size of the background, but there's no way to specify how big the background is. Either you cut out the icon you want, size it down and use it, or use something like the input field prepend/append option (http://twitter.github.io/bootstrap/base-css.html#forms and then search for prepended inputs).

you want after days find date this code try..

public Date getToDateAfterDays(Integer day) {
        Date nowdate = new Date();
        Calendar cal = Calendar.getInstance();
        cal.setTime(nowdate);
        cal.add(Calendar.DATE, day);
        return cal.getTime();
    }

with open("filename.txt", "w+") as file:
  for line in file:
    print line

This with statement automatically opens and closes it for you and you can iterate over the lines of the file with a simple for loop

You can also use the CSS calc() function to subtract the width of your padding from the percentage of your container's width.

An example:

width: calc((100%) - (32px))

Just be sure to make the subtracted width equal to the total padding, not just one half. If you pad both sides of the inner div with 16px, then you should subtract 32px from the final width, assuming that the example below is what you want to achieve.

.outer {_x000D_
  width: 200px;_x000D_
  height: 120px;_x000D_
  background-color: black;_x000D_
}_x000D_
_x000D_
.inner {_x000D_
  height: 40px;_x000D_
  top: 30px;_x000D_
  position: relative;_x000D_
  padding: 16px;_x000D_
  background-color: teal;_x000D_
}_x000D_
_x000D_
#inner-1 {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#inner-2 {_x000D_
  width: calc((100%) - (32px));_x000D_
}

<div class="outer" id="outer-1">_x000D_
  <div class="inner" id="inner-1"> width of 100% </div>_x000D_
</div>_x000D_
_x000D_
<br>_x000D_
<br>_x000D_
_x000D_
<div class="outer" id="outer-2">_x000D_
  <div class="inner" id="inner-2"> width of 100% - 16px </div>_x000D_
</div>

Is this a valid solution?

        IList<string> ilist = new List<string>();
        ilist.Add("B");
        ilist.Add("A");
        ilist.Add("C");

        Console.WriteLine("IList");
        foreach (string val in ilist)
            Console.WriteLine(val);
        Console.WriteLine();

        List<string> list = (List<string>)ilist;
        list.Sort();
        Console.WriteLine("List");
        foreach (string val in list)
            Console.WriteLine(val);
        Console.WriteLine();

        list = null;

        Console.WriteLine("IList again");
        foreach (string val in ilist)
            Console.WriteLine(val);
        Console.WriteLine();

The result was: IList B A C

List A B C

IList again A B C

Here's my variant:

  with_env() {
    (set -a && . ./.env && "$@")
  }

compared with the previous solutions:

• it does not leak variables outside scope (values from .env are not exposed to caller)
• does not clobber set options
• returns exit code of the executed command
• uses posix compatible set -a
• uses . instead of source to avoid bashism
• command is not invoked if .env loading fails

with_env rails console

Duplicate file finder

This will run checksums recursively from the current directory, and give back the filenames of all identical checksum results:

find ./ -type f -print0 | xargs -0 -n1 md5sum | sort -k 1,32 | uniq -w 32 -d --all-repeated=separate | sed -e 's/^[0-9a-f]*\ *//;'

You can, of course, change the path around.
Maybe put it into a function or alias, and pass in the target path as a parameter.

I do it with this simple examps

jQuery

$('.map').click(function(){
    $(this).find('iframe').addClass('clicked')
    }).mouseleave(function(){
    $(this).find('iframe').removeClass('clicked')
});

CSS

.map {
    width: 100%; 
}
.map iframe {
    width: 100%;
    display: block;
    pointer-events: none;
    position: relative; /* IE needs a position other than static */
}
.map iframe.clicked {
    pointer-events: auto;
}

Or use the gmap options

function init() { 
    var mapOptions = {  
        scrollwheel: false, 

Use showWarnings = FALSE:

dir.create(file.path(mainDir, subDir), showWarnings = FALSE)
setwd(file.path(mainDir, subDir))

dir.create() does not crash if the directory already exists, it just prints out a warning. So if you can live with seeing warnings, there is no problem with just doing this:

dir.create(file.path(mainDir, subDir))
setwd(file.path(mainDir, subDir))

Get Drawable from vector resource irrespective of, whether its vector or not:

AppCompatResources.getDrawable(context, R.drawable.icon);

Note:
ContextCompat.getDrawable(context, R.drawable.icon); will produce android.content.res.Resources$NotFoundException for vector resource.

Using sessionStorage for this is not possible.

From the MDN Docs

Opening a page in a new tab or window will cause a new session to be initiated.

That means that you can't share between tabs, for this you should use localStorage

As user 'Skip Head' already pointed out, csv or a any table file format would be a better fitt in your case.

If it is an option for you, maybe this Table implementation might interest you.

You can escape a ' in JavaScript like \'

Visit https://developers.google.com/mobile/add and try to fill "Android package name". In some cases it can write error: "Invalid Android package name".

In https://developer.android.com/studio/build/application-id.html it is written:

And although the application ID looks like a traditional Java package name, the naming rules for the application ID are a bit more restrictive:

• It must have at least two segments (one or more dots).
• Each segment must start with a letter.
• All characters must be alphanumeric or an underscore [a-zA-Z0-9_].

So, "0com.example.app" and "com.1example.app" are errors.

The paint() method supports painting via a Graphics object.

The repaint() method is used to cause paint() to be invoked by the AWT painting thread.

The difference between 'exec' and 'system' is that exec replaces your current program with 'command' and NEVER returns to your program. system, on the other hand, forks and runs 'command' and returns you the exit status of 'command' when it is done running. The back tick runs 'command' and then returns a string representing its standard out (whatever it would have printed to the screen)

You can also use popen to run shell commands and I think that there is a shell module - 'use shell' that gives you transparent access to typical shell commands.

Hope that clarifies it for you.

It can be done using javascript. Say your html/aspx code goes this way:

<span>Main heading</span>
<asp:Label ID="lbl1" runat="server" Text="Contents"></asp:Label>
<asp:Label Text="Contractor Name" ID="lblCont" runat="server"></asp:Label>
<div id="forPrintPreview">
  <asp:Label Text="Company Name" runat="server"></asp:Label>
  <asp:GridView runat="server">

      //GridView Content goes here

  </asp:GridView
</div>

<input type="button" onclick="PrintPreview();" value="Print Preview" />

Here on click of "Print Preview" button we will open a window with data for print. Observe that 'forPrintPreview' is the id of a div. The function for Print preview goes this way:

function PrintPreview() {
 var Contractor= $('span[id*="lblCont"]').html();
 printWindow = window.open("", "", "location=1,status=1,scrollbars=1,width=650,height=600");
 printWindow.document.write('<html><head>');
 printWindow.document.write('<style type="text/css">@media print{.no-print, .no-print *{display: none !important;}</style>');
 printWindow.document.write('</head><body>');
 printWindow.document.write('<div style="width:100%;text-align:right">');

  //Print and cancel button
 printWindow.document.write('<input type="button" id="btnPrint" value="Print" class="no-print" style="width:100px" onclick="window.print()" />');
 printWindow.document.write('<input type="button" id="btnCancel" value="Cancel" class="no-print"  style="width:100px" onclick="window.close()" />');

 printWindow.document.write('</div>');

 //You can include any data this way.
 printWindow.document.write('<table><tr><td>Contractor name:'+ Contractor +'</td></tr>you can include any info here</table');

 printWindow.document.write(document.getElementById('forPrintPreview').innerHTML);
 //here 'forPrintPreview' is the id of the 'div' in current page(aspx).
 printWindow.document.write('</body></html>');
 printWindow.document.close();
 printWindow.focus();
}

Observe that buttons 'print' and 'cancel' has the css class 'no-print', So these buttons will not appear in the print.

I needed to install various JetBrains tools on a number of machines from CLI, so I wrote a tiny tool to help with that. It also uses cleaner APIs from JB making it hopefully more stable, and works for various JB tools.

Feel free to try it: https://github.com/MarcinZukowski/jetbrains-installer

Click Insert ->Object->Create from file ->Browse.

Once the file is selected choose the "Change icon" option and you will be able to rename the file and change the icon if you wish.

Hope this helps!

Application Private Data files are stored within <internal_storage>/data/data/<package>

Files being stored in the internal storage can be accessed with openFileOutput() and openFileInput()

When those files are created as MODE_PRIVATE it is not possible to see/access them within another application such as a FileManager.

In 1.0 you should use:

io.sockets.connected[socketid].emit();

Working example. Notes below.

class Animal {
    constructor(public name) {
    }

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    move() {
        alert(this.name + " is Slithering...");
        super.move(5);
    }
}

class Horse extends Animal {
    move() {
        alert(this.name + " is Galloping...");
        super.move(45);
    }
}

var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");

sam.move();
tom.move(34);

1. You don't need to manually assign the name to a public variable. Using public name in the constructor definition does this for you.

2. You don't need to call super(name) from the specialised classes.

3. Using this.name works.

Notes on use of super.

This is covered in more detail in section 4.9.2 of the language specification.

The behaviour of the classes inheriting from Animal is not dissimilar to the behaviour in other languages. You need to specify the super keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move() or this.move() you would be dealing with the specialised Snake or Horse function, so using super.move() explicitly calls the base class function.

There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name and this.name - there is simply this.name. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.

In .Net Core (as of v2.2) it should be:

new Process
{
    StartInfo = new ProcessStartInfo(@"file path")
    {
        UseShellExecute = true
    }
}.Start();

Please read the whole answer before attempting to run with sudo

Try running sudo /dvtcolorconvert.rb ~/Themes/ObsidianCode.xccolortheme

The sudo command executes the commands which follow it with 'superuser' or 'root' privileges. This should allow you to execute almost anything from the command line. That said, DON'T DO THIS! If you are running a script on your computer and don't need it to access core components of your operating system (I'm guessing you're not since you are invoking the script on something inside your home directory (~/)), then it should be running from your home directory, ie:

~/dvtcolorconvert.rb ~/Themes/ObsidianCode.xccolortheme

Move it to ~/ or a sub directory and execute from there. You should never have permission issues there and there wont be a risk of it accessing or modifying anything critical to your OS.

If you are still having problems you can check the permissions on the file by running ls -l while in the same directory as the ruby script. You will get something like this:

$ ls -l  
total 13  
drwxr-xr-x    4 or019268 Administ    12288 Apr 10 18:14 TestWizard  
drwxr-xr-x    4 or019268 Administ     4096 Aug 27 12:41 Wizard.Controls  
drwxr-xr-x    5 or019268 Administ     8192 Sep  5 00:03 Wizard.UI  
-rw-r--r--    1 or019268 Administ     1375 Sep  5 00:03 readme.txt

You will notice that the readme.txt file says -rw-r--r-- on the left. This shows the permissions for that file. The 9 characters from the right can be split into groups of 3 characters of 'rwx' (read, write, execute). If I want to add execute rights to this file I would execute chmod 755 readme.txt and that permissions portion would become rwxr-xr-x. I can now execute this file if I want to by running ./readme.txt (./ tells the bash to look in the current directory for the intended command rather that search the $PATH variable).

schluchc alludes to looking at the man page for chmod, do this by running man chmod. This is the best way to get documentation on a given command, man <command>

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

If you also want to bind closing of infowindow to some event, try something like this

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow)); 

This was already in a comment, but deserves its own answer: Without editing the config files: in mysql, as root, do

SET global general_log_file='/tmp/mysql.log'; 
SET global log_output = 'file';
SET global general_log = on;

Don't forget to turn it off afterwards:

SET global general_log = off;

Yeah, it's pretty simple:

input[type="submit"]{
  background: #fff;
  border: 1px solid #000;
  text-shadow: 1px 1px 1px #000;
}

I recommend giving it an ID or a class so that you can target it more easily.

This works well. It's a manager I've made to handle hold events. Has events for hold, and for when you let go.

function onUserHold(element, func, hold, clearfunc) {
    //var holdTime = 0;
    var holdTimeout;

    element.addEventListener('mousedown', function(e) {
        holdTimeout = setTimeout(function() {
            func();
            clearTimeout(holdTimeout);
            holdTime = 0;
        }, hold);
        //alert('UU');
    });

    element.addEventListener('mouseup', clearTime);
    element.addEventListener('mouseout', clearTime);

    function clearTime() {
        clearTimeout(holdTimeout);
        holdTime = 0;
        if(clearfunc) {
            clearfunc();
        }
    }
}

The element parameter is the one which you hold. The func parameter fires when it holds for a number of milliseconds specified by the parameter hold. The clearfunc param is optional and if it is given, it will get fired if the user lets go or leaves the element. You can also do some work-arounds to get the features you want. Enjoy! :)

sometimes you just need to give the slave a kick too

try

stop slave;    
reset slave;    
start slave;    
show slave status;

quite often, slaves, they just get stuck guys :)

The following command will work for you, if you want to change default path. Just type this in bin directory of mongodb.

mongod --dbpath=yourdirectory\data\db

In case you want to move existing data too, then just copy all the folders from existing data\db directory to new directory before you execute the command.

And also stop existing mongodb services which are running.

You can use pthread_self()

The parent gets to know the thread id after the pthread_create() is executed sucessfully, but while executing the thread if we want to access the thread id we have to use the function pthread_self().

npm start -- --port "port number"

LAZY: It fetches the child entities lazily i.e at the time of fetching parent entity it just fetches proxy(created by cglib or any other utility) of the child entities and when you access any property of child entity then it is actually fetched by hibernate.

EAGER: it fetches the child entities along with parent.

For better understanding go to Jboss documentation or you can use hibernate.show_sql=true for your app and check the queries issued by the hibernate.

It is possible to handle these exceptions with Thread.setDefaultUncaughtExceptionHandler(), however this appears to mess with Android's method of handling exceptions. I attempted to use a handler of this nature:

private class ExceptionHandler implements Thread.UncaughtExceptionHandler {
    @Override
    public void uncaughtException(Thread thread, Throwable ex){
        Log.e(Constants.TAG, "uncaught_exception_handler: uncaught exception in thread " + thread.getName(), ex);

        //hack to rethrow unchecked exceptions
        if(ex instanceof RuntimeException)
            throw (RuntimeException)ex;
        if(ex instanceof Error)
            throw (Error)ex;

        //this should really never happen
        Log.e(Constants.TAG, "uncaught_exception handler: unable to rethrow checked exception");
    }
}

However, even with rethrowing the exceptions, I was unable to get the desired behavior, ie logging the exception while still allowing Android to shutdown the component it had happened it, so I gave up on it after a while.

Try this. Works on both windows or linux server..

str_replace('\\','/',dirname(dirname(__FILE__)))

As mentioned in this Jakob Nielsen article, drop down lists should be avoided for data that is well known to the user:

Menus of data well known to users, such as the month and year of their birth. Such information is often hardwired into users' fingers, and having to select such options from a menu breaks the standard paradigm for entering information and can even create more work for users.

The ideal solution is likely something like follows:

• Provide 3 separate text boxes for day, month, and year (labeled appropriately)
• Sort the text boxes according to the user's culture.
• Day and Month text boxes should be sized so that a 2 digit input is assumed.
• Year text box should be sized so that a 4 digit year is assumed.
• Allow the user to enter a 2 or 4 digit year. Assume a 2 digit year is 1900, and update the textbox to reflect this onBlur (or on a following confirmation step).
• Allow the user to enter either a month number OR month name.

EDIT: Here is how we implemented our DOB picker: Masked text input field with HTML5 regex to force the numeric keyboard on iOS devices.

This was a fun question! Another way to handle this for variable length lists is to build a function that takes full advantage of the .format method and list unpacking. In the following example I don't use any fancy formatting, but that can easily be changed to suit your needs.

list_1 = [1,2,3,4,5,6]
list_2 = [1,2,3,4,5,6,7,8]

# Create a function that can apply formatting to lists of any length:
def ListToFormattedString(alist):
    # Create a format spec for each item in the input `alist`.
    # E.g., each item will be right-adjusted, field width=3.
    format_list = ['{:>3}' for item in alist] 

    # Now join the format specs into a single string:
    # E.g., '{:>3}, {:>3}, {:>3}' if the input list has 3 items.
    s = ','.join(format_list)

    # Now unpack the input list `alist` into the format string. Done!
    return s.format(*alist)

# Example output:
>>>ListToFormattedString(list_1)
'  1,  2,  3,  4,  5,  6'
>>>ListToFormattedString(list_2)
'  1,  2,  3,  4,  5,  6,  7,  8'

These solutions are pretty good, but they are forgetting that there may be other status codes than 200 OK. This is a solution that I've used on production environments for status monitoring and such.

If there is a url redirect or some other condition on the target page, the return will be true using this method. Also, GetResponse() will throw an exception and hence you will not get a StatusCode for it. You need to trap the exception and check for a ProtocolError.

Any 400 or 500 status code will return false. All others return true. This code is easily modified to suit your needs for specific status codes.

/// <summary>
/// This method will check a url to see that it does not return server or protocol errors
/// </summary>
/// <param name="url">The path to check</param>
/// <returns></returns>
public bool UrlIsValid(string url)
{
    try
    {
        HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest;
        request.Timeout = 5000; //set the timeout to 5 seconds to keep the user from waiting too long for the page to load
        request.Method = "HEAD"; //Get only the header information -- no need to download any content

        using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
        {
            int statusCode = (int)response.StatusCode;
            if (statusCode >= 100 && statusCode < 400) //Good requests
            {
                return true;
            }
            else if (statusCode >= 500 && statusCode <= 510) //Server Errors
            {
                //log.Warn(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
                Debug.WriteLine(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
                return false;
            }
        }
    }
    catch (WebException ex)
    {
        if (ex.Status == WebExceptionStatus.ProtocolError) //400 errors
        {
            return false;
        }
        else
        {
            log.Warn(String.Format("Unhandled status [{0}] returned for url: {1}", ex.Status, url), ex);
        }
    }
    catch (Exception ex)
    {
        log.Error(String.Format("Could not test url {0}.", url), ex);
    }
    return false;
}

Unfortunately neither display:inline-block nor width:0px works in Internet Explorer up to version 8. I have not tried Internet Explorer 9. Much as I would like to ignore Internet Explorer, I can't.

The only option that works on Firefox and Internet Explorer 8 is float:left. The only slight drawback is that you have to remember to use clear:both on the element that follows the form. Of course, it will be very obvious if you forget ;-)

Something like:

clients.stream.filter(c->{
   users.stream.filter(u->u.getName().equals(c.getName()).count()>0
}).collect(Collectors.toList());

This is however not an awfully efficient way to do it. Unless the collections are very small, you will be better of building a set of user names and using that in the condition.

strings.Join() from the "strings" package

If you have a type mismatch(like if you are trying to join an int and a string), you do RANDOMTYPE (thing you want to change)

EX:

package main

import (
    "fmt"
    "strings"
)

var intEX = 0
var stringEX = "hello all you "
var stringEX2 = "people in here"


func main() {
    s := []string{stringEX, stringEX2}
    fmt.Println(strings.Join(s, ""))
}

Output :

hello all you people in here

new String(byteArray, Charset.defaultCharset())

This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.

As far as I'm aware in order to format a date value you have to handle it in parameterMap,

$('#listDiv').kendoGrid({
            dataSource: {
                type: 'json',
                serverPaging: true,
                pageSize: 10,
                transport: {
                    read: {
                        url: '@Url.Action("_ListMy", "Placement")',
                        data: refreshGridParams,
                        type: 'POST'
                    },
                    parameterMap: function (options, operation) {
                        if (operation != "read") {
                            var d = new Date(options.StartDate);
                            options.StartDate = kendo.toString(new Date(d), "dd/MM/yyyy");
                            return options;
                        }
                        else { return options; }

                    }
                },
                schema: {
                    model: {
                        id: 'Id',
                        fields: {
                            Id: { type: 'number' },
                            StartDate: { type: 'date', format: 'dd/MM/yyyy' },
                            Area: { type: 'string' },
                            Length: { type: 'string' },
                            Display: { type: 'string' },
                            Status: { type: 'string' },
                            Edit: { type: 'string' }
                        }
                    },
                    data: "Data",
                    total: "Count"
                }
            },
            scrollable: false,
            columns:
                [
                    {
                        field: 'StartDate',
                        title: 'Start Date',
                        format: '{0:dd/MM/yyyy}',
                        width: 100
                    },

If you follow the above example and just renames objects like 'StartDate' then it should work (ignore 'data: refreshGridParams,')

Completeness

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

And to consume the hidden ID input back on your Edit action method:

[HttpPost]
public ActionResult Edit(FormCollection collection)
{
    ViewModel.ID = Convert.ToInt32(collection["ID"]);
}

First subtract the pivot point (cx,cy), then rotate it, then add the point again.

Untested:

POINT rotate_point(float cx,float cy,float angle,POINT p)
{
  float s = sin(angle);
  float c = cos(angle);

  // translate point back to origin:
  p.x -= cx;
  p.y -= cy;

  // rotate point
  float xnew = p.x * c - p.y * s;
  float ynew = p.x * s + p.y * c;

  // translate point back:
  p.x = xnew + cx;
  p.y = ynew + cy;
  return p;
}

Try the following:

java -cp jar1:jar2:jar3:dir1:. HelloWorld

The default classpath (unless there is a CLASSPATH environment variable) is the current directory so if you redefine it, make sure you're adding the current directory (.) to the classpath as I have done.

Using D3:

If you want to add the element in the reverse order to the data use:

.insert('g', ":first-child")

Instead of .append

Adding an element to top of a group element

On Fedora 22, you need to do this instead:

sudo dnf install python-devel
sudo dnf install openldap-devel

While most people will tell you to just use multiple repositories, I feel it's worth mentioning there are other solutions.

Solution 1

A single repository can contain multiple independent branches, called orphan branches. Orphan branches are completely separate from each other; they do not share histories.

git checkout --orphan BRANCHNAME

This creates a new branch, unrelated to your current branch. Each project should be in its own orphaned branch.

Now for whatever reason, git needs a bit of cleanup after an orphan checkout.

rm .git/index
rm -r *

Make sure everything is committed before deleting

Once the orphan branch is clean, you can use it normally.

Solution 2

Avoid all the hassle of orphan branches. Create two independent repositories, and push them to the same remote. Just use different branch names for each repo.

# repo 1
git push origin master:master-1

# repo 2
git push origin master:master-2

I tried above solutions but only the below worked for me.

sudo apt-get update
sudo apt-get install --no-install-recommends nvidia-384 libcuda1-384 nvidia-opencl-icd-384
sudo reboot

If you truly want to "grep" the formatted output (display strings) then go with Mike's approach. There are definitely times where this comes in handy. However if you want to try embracing PowerShell's object pipeline nature, then try this. First, check out the properties on the objects flowing down the pipeline:

PS> alias | Get-Member


   TypeName: System.Management.Automation.AliasInfo

Name                MemberType     Definition
----                ----------     ----------
Equals              Method         bool Equals(System.Object obj)
GetHashCode         Method         int GetHashCode()
GetType             Method         type GetType()
ToString            Method         string ToString()
<snip>
*Definition*        Property       System.String Definition {get;}
<snip>

Note the Definition property which is a header you see when you display the output of Get-Alias (alias) e.g.:

PS> alias

CommandType     Name           *Definition*
-----------     ----           ----------
Alias           %              ForEach-Object
<snip>

Usually the header title matches the property name but not always. That is where using Get-Member comes in handy. It shows you what you need to "script" against. Now if what you want to "grep" is the Definition property contents then consider this. Rather than just grepping that one property's value, you can instead filter each AliasInfo object in the pipepline by the contents of this property and you can use a regex to do it e.g.:

PS> alias | Where-Object {$_.Definition -match 'alias'}

CommandType     Name                   Definition
-----------     ----                   ----------
Alias           epal                   Export-Alias
Alias           gal                    Get-Alias
Alias           ipal                   Import-Alias
Alias           nal                    New-Alias
Alias           sal                    Set-Alias

In this example I use the Where-Object cmdlet to filter objects based on some arbitrary script. In this case, I filter by the Defintion property matched against the regex 'alias'. Only those objects that return true for that filter are allowed to propagate down the pipeline and get formatted for display on the host.

BTW if you're typing this, then you can use one of two aliases for Where-Object - 'Where' or '?'. For example:

PS> gal | ?{$_.Definition -match '-Item*'}

You can use Httpful :

Website : http://phphttpclient.com/

Github : https://github.com/nategood/httpful

This problem occurs because of UAC and only when you are running IE on the same computer SSRS is on.

To fix it, you have to add an AD group of the users with read priviledges to the actual SSRS website directories and push the security down. UAC is dumb in how if you are an admin on the box. It won't let you access the data unless you also have access to the data through other means such as a non-administrator AD group that is applied to the files.

A programmer solution:

• Create a bit map (a matrix of boolean values). It can be as large as you want.
• Draw a circle in that bit map.
• Create a lookup table of the circle's points.
• Choose a random index in this lookup table.

const int RADIUS = 64;
const int MATRIX_SIZE = RADIUS * 2;

bool matrix[MATRIX_SIZE][MATRIX_SIZE] = {0};

struct Point { int x; int y; };

Point lookupTable[MATRIX_SIZE * MATRIX_SIZE];

void init()
{
  int numberOfOnBits = 0;

  for (int x = 0 ; x < MATRIX_SIZE ; ++x)
  {
    for (int y = 0 ; y < MATRIX_SIZE ; ++y)
    {
      if (x * x + y * y < RADIUS * RADIUS) 
      {
        matrix[x][y] = true;

        loopUpTable[numberOfOnBits].x = x;
        loopUpTable[numberOfOnBits].y = y;

        ++numberOfOnBits;

      } // if
    } // for
  } // for
} // ()

Point choose()
{
  int randomIndex = randomInt(numberOfBits);

  return loopUpTable[randomIndex];
} // ()

The bitmap is only necessary for the explanation of the logic. This is the code without the bitmap:

const int RADIUS = 64;
const int MATRIX_SIZE = RADIUS * 2;

struct Point { int x; int y; };

Point lookupTable[MATRIX_SIZE * MATRIX_SIZE];

void init()
{
  int numberOfOnBits = 0;

  for (int x = 0 ; x < MATRIX_SIZE ; ++x)
  {
    for (int y = 0 ; y < MATRIX_SIZE ; ++y)
    {
      if (x * x + y * y < RADIUS * RADIUS) 
      {
        loopUpTable[numberOfOnBits].x = x;
        loopUpTable[numberOfOnBits].y = y;

        ++numberOfOnBits;
      } // if
    } // for
  } // for
} // ()

Point choose()
{
  int randomIndex = randomInt(numberOfBits);

  return loopUpTable[randomIndex];
} // ()

Do Following steps:

1. Start Android Studio.
2. Close any open project.Go to File > Close Project.(Welcome window will open)
3. Go to Configure > Settings.
4. On Settings dialog,select Compiler (Gradle-based Android Projects) from left and set VM Options to -Xmx512m(i.e. write -Xmx512m under VM Options:) and press OK.

Another alternative would be to show a Toast/Snackbar on the first back press asking to press back again to Exit, which is a lot less intrusive than showing an AlertDialog to confirm if user wants to exit the app.

You can use the DoubleBackPress Android Library to achieve this with a few lines of code. Example GIF showing similar behaviour.

To begin with, add the dependency to your application :

dependencies {
    implementation 'com.github.kaushikthedeveloper:double-back-press:0.0.1'
}

Next, in your Activity, implement the required behaviour.

// set the Toast to be shown on FirstBackPress (ToastDisplay - builtin template)
// can be replaced by custom action (new FirstBackPressAction{...})
FirstBackPressAction firstBackPressAction = new ToastDisplay().standard(this);

// set the Action on DoubleBackPress
DoubleBackPressAction doubleBackPressAction = new DoubleBackPressAction() {
    @Override
    public void actionCall() {
        // TODO : Exit the application
        finish();
        System.exit(0);
    }
};

// setup DoubleBackPress behaviour : close the current Activity
DoubleBackPress doubleBackPress = new DoubleBackPress()
        .withDoublePressDuration(3000)     // msec - wait for second back press
        .withFirstBackPressAction(firstBackPressAction)
        .withDoubleBackPressAction(doubleBackPressAction);

Finally, set this as the behaviour on back press.

@Override
public void onBackPressed() {
    doubleBackPress.onBackPressed();
}

You can use backslash for line continuation. However note that the shell receives the whole command concatenated into a single line, so you also need to terminate some of the lines with a semicolon:

foo:
    for i in `find`;     \
    do                   \
        all="$$all $$i"; \
    done;                \
    gcc $$all

But if you just want to take the whole list returned by the find invocation and pass it to gcc, you actually don't necessarily need a multiline command:

foo:
    gcc `find`

Or, using a more shell-conventional $(command) approach (notice the $ escaping though):

foo:
    gcc $$(find)

For future reference, you can quickly create a truth table to check if it evaluates the way you want... it's kind of like Sudoku.

(!isset($action)) && ($action != "add" && $action != "delete"))

Example:

column 1 is issetaction, column 2 and 3 evaluates !="add","delete" respectively

if($a=nothing) T && (T && T) => T && T => TRUE

TWO CASES

There are two situations possible when we talk about passing data between activities.

Let's say there are two activities A and B and there is a String X. and you are in Activity A.

Now let's see the two cases

1. A-------->B
2. A<--------B

CASE 1:
String X is in A and you want to get it in Activity B.

It is very straightforward.

In Activity A.

1) Create Intent
2) Put Extra value
3) startActivity

Intent i = new Intent(A.this, B.class);
i.putExtra("Your_KEY",X);
startActivity(i)

In Activity B

Inside onCreate() method retrieve string X using the key which you used while storing X (Your_KEY).

Intent i = getIntent();
String s = i.getStringExtra("Your_KEY");

Case 2:
This case is little tricky if u are new to Android development Because you are in Activity A, you move to Activity B, collect the string, move back to Activity A and retrieve the collected String or data. Let's see how to deal with this situation.

In Activity A
1) Create Intent
2) start an activity with a request code.

Intent i = new Intent(A.this, B.class);
startActivityForResult(i,your_req_code);

In Activity B
1) Put string X in intent
2) Set result
3) Finish activity

Intent returnIntent = new Intent();
returnIntent .putString("KEY",X);
setResult(resCode,returnIntent);   // for the first argument, you could set Activity.RESULT_OK or your custom rescode too
finish();

Again in Activity A
1) Override onActivityResult method

onActivityResult(int req_code, int res_code, Intent data)
{
       if(req_code==your_req_code)
       {
          String X = data.getStringExtra("KEY")
       }
}

Further understanding of Case 2

You might wonder what is the reqCode, resCode in the onActivityResult(int reqCode, resCode, Intent data)

reqCode is useful when you have to identify from which activity you are getting the result from.

Let's say you have two buttons, one button starts Camera (you click a photo and get the bitmap of that image in your Activity as a result), another button starts GoogleMap( you get back the current coordinates of your location as a result). So to distinguish between the results of both activities you start CameraActivty and MapActivity with different request codes.

resCode: is useful when you have to distinguish between how results are coming back to requesting activity.

For eg: You start Camera Activity. When the camera activity starts, you could either take a photo or just move back to requesting activity without taking a photo with the back button press. So in these two situations, your camera activity sends result with different resCode ACTIVITY.RESULT_OK and ACTIVITY.RESULT_CANCEL respectively.

i had a similar problem with the editText, which gained focus since the activity was started. this problem i fixed easily like this:

you add this piece of code into the layout that contains the editText in xml:

    android:id="@+id/linearlayout" 
    android:focusableInTouchMode="true"

dont forget the android:id, without it i've got an error.

the other problem i had with the editText is that once it gain the first focus, the focus never disappeared. this is a piece of my code in java, it has an editText and a button that captures the text in the editText:

    editText=(EditText) findViewById(R.id.et1);
    tvhome= (TextView)findViewById(R.id.tv_home);
    etBtn= (Button) findViewById(R.id.btn_homeadd);
    etBtn.setOnClickListener(new View.OnClickListener() 
    {   
        @Override
        public void onClick(View v)
        {
            tvhome.setText( editText.getText().toString() );

            //** this code is for hiding the keyboard after pressing the button
            View view = Settings.this.getCurrentFocus();
            if (view != null) 
            {  
                InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            }
            //**

            editText.getText().clear();//clears the text
            editText.setFocusable(false);//disables the focus of the editText 
            Log.i("onCreate().Button.onClickListener()", "et.isfocused= "+editText.isFocused());
        }
    });
    editText.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            if(v.getId() == R.id.et1)
            {
                v.setFocusableInTouchMode(true);// when the editText is clicked it will gain focus again

                //** this code is for enabling the keyboard at the first click on the editText
                if(v.isFocused())//the code is optional, because at the second click the keyboard shows by itself
                {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
                }
                //**

                Log.i("onCreate().EditText.onClickListener()", "et.isfocused= "+v.isFocused());
            }
            else
                Log.i("onCreate().EditText.onClickListener()", "the listener did'nt consume the event");
        }
    });

hope it will help to some of you!

I have solved the issue by using UINavigationController when presenting. In MainVC, when presenting VC1

let vc1 = VC1()
let navigationVC = UINavigationController(rootViewController: vc1)
self.present(navigationVC, animated: true, completion: nil)

In VC1, when I would like to show VC2 and dismiss VC1 in same time (just one animation), I can have a push animation by

let vc2 = VC2()
self.navigationController?.setViewControllers([vc2], animated: true)

And in VC2, when close the view controller, as usual we can use:

self.dismiss(animated: true, completion: nil)

MicroMVC has a 13 KB ORM that only relies on a 8 KB database class. It also returns all results as ORM objects themselves and uses late static binding to avoid embedding information about the current object's table and meta data into each object. This results in the cheapest ORM overhead there is.

It works with MySQL, PostgreSQL, and SQLite.

byte[] result = new byte[a.length + b.length];
// copy a to result
System.arraycopy(a, 0, result, 0, a.length);
// copy b to result
System.arraycopy(b, 0, result, a.length, b.length);

You want to use DATEADD, using a negative duration. e.g.

DATEADD(minute, -15, '2000-01-01 08:30:00') 

I'm just starting to use EC2 myself so not an expert, but Amazon's own documentation says:

we recommend that you use the local instance store for temporary data and, for data requiring a higher level of durability, we recommend using Amazon EBS volumes or backing up the data to Amazon S3.

Emphasis mine.

I do more data analysis than web hosting, so persistence doesn't matter as much to me as it might for a web site. Given the distinction made by Amazon itself, I wouldn't assume that EBS is right for everyone.

I'll try to remember to weigh in again after I've used both.

I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:

GET approach with JSON result

curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool 

POST approach with JSON result

curl -X POST  -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool

After you've run the Inspect by Name, select all the locations, and make use of the Apply quick fixes to all the problems drop-down, and use either (or both) of Delete unused parameter(s) and Safe Delete.

Don't forget to hit Do Refactor afterwards.

Then you'll need to run another analysis, as the refactored code will no doubt reveal more unused declarations.

None of the answers here actually helped my case (proxy + password), instead I found a solution on a Github issue:

https://github.com/rubygems/rubygems/issues/1068

Basically I had to set three variables:

set http_proxy=proxy_ip:port
set http_proxy_user=user
set http_proxy_pass=password

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

PRINT DATEDIFF(DAY, '1/1/2011', '3/1/2011') will give you what you're after.

This gives the number of times the midnight boundary is crossed between the two dates. You may decide to need to add one to this if you're including both dates in the count - or subtract one if you don't want to include either date.

Views are essentially logical table-like structures populated on the fly by a given query. The results of a view query are not stored anywhere on disk and the view is recreated every time the query is executed. Materialized views are actual structures stored within the database and written to disk. They are updated based on the parameters defined when they are created.

Bytes are transparently converted to ints.

Just say

int i= rno[0];

I was running a PowerShell script into the task scheduller but i forgot to enable the execution-policy to unrestricted, in an elevated PowerShell console:

After that, the error disappeared (0x1).

In addition to all the other answers, you could use switch. But it does seem a bit long.

switch ($result->vocation) {
case 1:
    echo 'Sorcerer';
    break;

case 2:
    echo 'Druid';
    break;

case 3:
    echo 'Paladin';
    break;

case 4:
    echo 'Knight';
    break;

case 5:
    echo 'Master Sorcerer';
    break;

case 6:
    echo 'Elder Druid';
    break;

case 7:
    echo 'Royal Paladin';
    break;

default:
    echo 'Elite Knight';
    break;
}

Would the following Macro help you?

Sub activateSheet(sheetname As String)
'activates sheet of specific name
    Worksheets(sheetname).Activate
End Sub

Basically you want to make use of the .Activate function. Or you can use the .Select function like so:

Sub activateSheet(sheetname As String)
'selects sheet of specific name
    Sheets(sheetname).Select
End Sub

public static PhysicalAddress GetMacAddress()
{
    var myInterfaceAddress = NetworkInterface.GetAllNetworkInterfaces()
        .Where(n => n.OperationalStatus == OperationalStatus.Up && n.NetworkInterfaceType != NetworkInterfaceType.Loopback)
        .OrderByDescending(n => n.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
        .Select(n => n.GetPhysicalAddress())
        .FirstOrDefault();

    return myInterfaceAddress;
}

Basically:

Use IncludeErrorDetailPolicy instead if CustomErrors doesn't solve it for you (e.g. if you're ASP.NET stack is >2012):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Note: Be careful returning detailed error info can reveal sensitive information to 'hackers'. See Simon's comment on this answer below.

TL;DR version

For me CustomErrors didn't really help. It was already set to Off, but I still only got a measly an error has occurred message. I guess the accepted answer is from 3 years ago which is a long time in the web word nowadays. I'm using Web API 2 and ASP.NET 5 (MVC 5) and Microsoft has moved away from an IIS-only strategy, while CustomErrors is old skool IIS ;).

Anyway, I had an issue on production that I didn't have locally. And then found I couldn't see the errors in Chrome's Network tab like I could on my dev machine. In the end I managed to solve it by installing Chrome on my production server and then browsing to the app there on the server itself (e.g. on 'localhost'). Then more detailed errors appeared with stack traces and all.

Only afterwards I found this article from Jimmy Bogard (Note: Jimmy is mr. AutoMapper!). The funny thing is that his article is also from 2012, but in it he already explains that CustomErrors doesn't help for this anymore, but that you CAN change the 'Error detail' by setting a different IncludeErrorDetailPolicy in the global WebApi configuration (e.g. WebApiConfig.cs):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Luckily he also explains how to set it up that webapi (2) DOES listen to your CustomErrors settings. That's a pretty sensible approach, and this allows you to go back to 2012 :P.

Note: The default value is 'LocalOnly', which explains why I was able to solve the problem the way I described, before finding this post. But I understand that not everybody can just remote to production and startup a browser (I know I mostly couldn't until I decided to go freelance AND DevOps).

In addition to gotomanners answer, in case anyone else came here looking for a null safe solution to the same problem, this is what I ended up with

    printf("Table myCity successfully created.\n");
}

/* Select queries return a resultset */
if ($result = $mysqli->query("SELECT Name FROM City LIMIT 10")) {
    printf("Select returned %d rows.\n", $result->num_rows);

    /* free result set */
    $result->close();
}

/* If we have to retrieve large amount of data we use MYSQLI_USE_RESULT */
if ($result = $mysqli->query("SELECT * FROM City", MYSQLI_USE_RESULT)) {

    /* Note, that we can't execute any functions which interact with the
       server until result set was closed. All calls will return an
       'out of sync' error */
    if (!$mysqli->query("SET @a:='this will not work'")) {
        printf("Error: %s\n", $mysqli->error);
    }
    $result->close();
}

If you use RecycleView, first you need more efford to setup. You need to give more time to setup simple Item onclick, border, touch event and other simple thing. But end product will be perfect.

So decision is yours. I suggest, if you design simple app like phonebook loading, where simple click of item is enough, you can implement listview. But if you design like social media home page with unlimited scrolling. Several different decoration between item, much control of individual item than use recycle view.

I had this same problem, however in a little bit different situation. One day my application launches fine (using developer provision), then I do some minor editing to my Entitlements file, and after that it stops working. The application installed fine on my device, however every time I tried to launch it, it exited instantly (after the opening animation). (As I made edits to other files too, I did not suspect the following problem)

The problem was in the Entitlements file format, seems so that the following declarations are not the same:

Correct:

<key>get-task-allow</key>
<true/>

Incorrect:

<key>get-task-allow</key>
<true />

Altough it's an XML format, do not use spaces in the tag or the Xcode will not be able to connect to the process.

I was using developer provisioning profile all along.

Edit: Also make sure the line ending in your Entitlements file are \n (LF) instead of \r\n (CRLF). If you edit the entitlements file on Windows using CRLF line endings may cause your application to fail to launch.

you can use this:

box-shadow: inset 0 0 0 1000px rgba(0,0,0,.2);

as seen on: https://stackoverflow.com/a/24084708/8953378

The line function implementation should be:

void addStudent(struct student person) {

}

person is not a type but a variable, you cannot use it as the type of a function parameter.

Also, make sure your struct is defined before the prototype of the function addStudent as the prototype uses it.

Performance is almost always about good design and optimized database interactions. Ruby does what most web sites need quite fast, especially more recent versions; and the speed of development and ease of maintenance provides a large payoff in costs and in keeping customers happy. I find JAVA to have slow execution performance for some tasks, and given the difficulty of developing in JAVA, many developers create slow applications regardless of the theoretical speed capability as demonstrated in benchmarks (benchmarks are generally contrived to show a specific and narrow capability). When I need intensive processing that isn't well suited to my database's capabilities, I choose C or Objective-C or some other truly high performance compiled language for those tasks depending on the platform. If I need to create a databased web application, I use RoR or sometimes C# ASP.NET depending on other requirements; because all platforms have strengths and weaknesses. Execution speed of the things your application does is important, but after all, if execution performance of one narrow aspect of a language is all that counts; then I might still be using Assembler language for everything.

Yes - you can create encapsulated property, but it's not been done with access modifiers (public|private) at least not with ES6.

Here is a simple example how it can be done with ES6:

1 Create class using class word

2 Inside it's constructor declare block-scoped variable using let OR const reserved words -> since they are block-scope they cannot be accessed from outside (encapsulated)

3 To allow some access control (setters|getters) to those variables you can declare instance method inside it's constructor using: this.methodName=function(){} syntax

"use strict";
    class Something{
        constructor(){
            //private property
            let property="test";
            //private final (immutable) property
            const property2="test2";
            //public getter
            this.getProperty2=function(){
                return property2;
            }
            //public getter
            this.getProperty=function(){
                return property;
            }
            //public setter
            this.setProperty=function(prop){
                property=prop;
            }
        }
    }

Now lets check it:

var s=new Something();
    console.log(typeof s.property);//undefined 
    s.setProperty("another");//set to encapsulated `property`
    console.log(s.getProperty());//get encapsulated `property` value
    console.log(s.getProperty2());//get encapsulated immutable `property2` value

Depending on what you want to do with the list, you may not even need to cast it to a List<Customer>. If you only want to add Customer objects to the list, you could declare it as follows:

...
List<Object> list = getList();
return (List<? super Customer>) list;

This is legal (well, not just legal, but correct - the list is of "some supertype to Customer"), and if you're going to be passing it into a method that will merely be adding objects to the list then the above generic bounds are sufficient for this.

On the other hand, if you want to retrieve objects from the list and have them strongly typed as Customers - then you're out of luck, and rightly so. Because the list is a List<Object> there's no guarantee that the contents are customers, so you'll have to provide your own casting on retrieval. (Or be really, absolutely, doubly sure that the list will only contain Customers and use a double-cast from one of the other answers, but do realise that you're completely circumventing the compile-time type-safety you get from generics in this case).

Broadly speaking it's always good to consider the broadest possible generic bounds that would be acceptable when writing a method, doubly so if it's going to be used as a library method. If you're only going to read from a list, use List<? extends T> instead of List<T>, for example - this gives your callers much more scope in the arguments they can pass in and means they are less likely to run into avoidable issues similar to the one you're having here.

Just one command did the work

netsh http add iplisten 127.0.0.1

this referes to the object the onclick method belongs to. So inside func this would be the DOM node of the a element and this.innerText would be here.

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

How about using string.Join instead of all the foreach Loops?

According to the below article:

http://tools.ietf.org/html/rfc3696 (Page 6, Section 3)

It's mentioned that:

"There is a length limit on email addresses. That limit is a maximum of 64 characters (octets) in the "local part" (before the "@") and a maximum of 255 characters (octets) in the domain part (after the "@") for a total length of 320 characters. Systems that handle email should be prepared to process addresses which are that long, even though they are rarely encountered."

So, the maximum total length for an email address is 320 characters ("local part": 64 + "@": 1 + "domain part": 255 which sums to 320)

Here's what I've found to work:

f_rd = open(path, 'r')
file_lines = f_rd.readlines()
f_rd.close()

matches = [line for line in file_lines if "chars of Interest" in line]
index = file_lines.index(matches[0])

As a complement of @stefano 's answer, It is better to use command with -f when generate a new SSH key for another account,

ssh-keygen -t rsa -f ~/.ssh/id_rsa_work -C "[email protected]"

Since id_rsa_work file doesn't exist in path ~/.ssh/, and I create this file manually, and it doesn't work :(

You could put a _ViewStart.cshtml file inside the /Views/Public folder which would override the default one in the /Views folder and specify the desired layout:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

By analogy you could put another _ViewStart.cshtml file inside the /Views/Staff folder with:

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

You could also specify which layout should be used when returning a view inside a controller action but that's per action:

return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);

Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.

UPDATE:

As requested in the comments section here's an example of an action filter which would choose a master page:

public class LayoutInjecterAttribute : ActionFilterAttribute
{
    private readonly string _masterName;
    public LayoutInjecterAttribute(string masterName)
    {
        _masterName = masterName;
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        var result = filterContext.Result as ViewResult;
        if (result != null)
        {
            result.MasterName = _masterName;
        }
    }
}

and then decorate a controller or an action with this custom attribute specifying the layout you want:

[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
    return View();
}

Inf is infinity, it's a "bigger than all the other numbers" number. Try subtracting anything you want from it, it doesn't get any smaller. All numbers are < Inf. -Inf is similar, but smaller than everything.

NaN means not-a-number. If you try to do a computation that just doesn't make sense, you get NaN. Inf - Inf is one such computation. Usually NaN is used to just mean that some data is missing.

A little late here, but I've found this to be a common problem worth a custom directive to handle. Here's how that might look:

  .directive('toggleOnHover', function(){
    return {
      restrict: 'A',
      link: link
    };

    function link(scope, elem, attrs){
      elem.on('mouseenter', applyToggleExp);
      elem.on('mouseleave', applyToggleExp);

      function applyToggleExp(){
        scope.$apply(attrs.toggleOnHover);
      }
    }

  });

You can use it like this:

<li toggle-on-hover="editableProp = !editableProp">edit</li> 

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

In simple terms

• Coarse-grained - larger components than fine-grained, large subcomponents. Simply wraps one or more fine-grained services together into a more coarse­-grained operation.
• Fine-grained - smaller components of which the larger ones are composed, lower­level service

It is better to have more coarse-grained service operations, which are composed by fine-grained operations

Although it might be tempting to expose an object on the isolated scope of a directive to facilitate communicating with it, doing can lead to confusing "spaghetti" code, especially if you need to chain this communication through a couple levels (controller, to directive, to nested directive, etc.)

We originally went down this path but after some more research found that it made more sense and resulted in both more maintainable and readable code to expose events and properties that a directive will use for communication via a service then using $watch on that service's properties in the directive or any other controls that would need to react to those changes for communication.

This abstraction works very nicely with AngularJS's dependency injection framework as you can inject the service into any items that need to react to those events. If you look at the Angular.js file, you'll see that the directives in there also use services and $watch in this manner, they don't expose events over the isolated scope.

Lastly, in the case that you need to communicate between directives that are dependent on one another, I would recommend sharing a controller between those directives as the means of communication.

AngularJS's Wiki for Best Practices also mentions this:

Only use .$broadcast(), .$emit() and .$on() for atomic events Events that are relevant globally across the entire app (such as a user authenticating or the app closing). If you want events specific to modules, services or widgets you should consider Services, Directive Controllers, or 3rd Party Libs

• $scope.$watch() should replace the need for events
• Injecting services and calling methods directly is also useful for direct communication
• Directives are able to directly communicate with each other through directive-controllers

This works for me I'm using Windows 10

git config --global credential.helper wincred

Going down your list:

• "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself, not to any particular encoding.
• UTF-16: 2 bytes per "code unit". This is the native format of strings in .NET, and generally in Windows and Java. Values outside the Basic Multilingual Plane (BMP) are encoded as surrogate pairs. These used to be relatively rarely used, but now many consumer applications will need to be aware of non-BMP characters in order to support emojis.
• UTF-8: Variable length encoding, 1-4 bytes per code point. ASCII values are encoded as ASCII using 1 byte.
• UTF-7: Usually used for mail encoding. Chances are if you think you need it and you're not doing mail, you're wrong. (That's just my experience of people posting in newsgroups etc - outside mail, it's really not widely used at all.)
• UTF-32: Fixed width encoding using 4 bytes per code point. This isn't very efficient, but makes life easier outside the BMP. I have a .NET Utf32String class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)
• ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc.
• ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

There's more on my Unicode page and tips for debugging Unicode problems.

The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.

From linux 14.04 to MySql 5.7, using cat command piped with mysql login:

cat /Desktop/test.sql | sudo mysql -uroot -p 

You can use this method for many MySQL commands to execute directly from Shell. Eg:

echo "USE my_db; SHOW tables;" | sudo mysql -uroot -p 

Make sure you separate your commands with semicolon (';').

I didn't see this approach in the answers above and thought it is a good contribution.

I just wanted to leave a detail summary on how to fix this issue at the current moment (this worked for me):

First go to the local installation of homebrew

cd /usr/local/Homebrew/

Homebrew > 2.5 remove the option to install formulas directly from git repos so we need to checkout an older version

git checkout 2.3.0

Install icu4c version (in my case 64.2 was compitable with [email protected])

HOMEBREW_NO_AUTO_UPDATE=1 brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

Go back to current version of homebrew

git checkout -

Tell brew to use the old version of icu4c this way you can chose wich version to use if you have both intalled

brew switch icu4c 64.2

Update 2020:

You can now use Modern ECMAScript syntax thanks to V8 Runtime.

You can use includes():

var grade = itemResponse.getResponse();
if(grade.includes("9th")){do something}

EDIT:

Since 1.10, strings.Builder exists. Example:

buf := new(strings.Builder)
n, err := io.Copy(buf, r)
// check errors
fmt.Println(buf.String())

OUTDATED INFORMATION BELOW

The short answer is that it it will not be efficient because converting to a string requires doing a complete copy of the byte array. Here is the proper (non-efficient) way to do what you want:

buf := new(bytes.Buffer)
buf.ReadFrom(yourReader)
s := buf.String() // Does a complete copy of the bytes in the buffer.

This copy is done as a protection mechanism. Strings are immutable. If you could convert a []byte to a string, you could change the contents of the string. However, go allows you to disable the type safety mechanisms using the unsafe package. Use the unsafe package at your own risk. Hopefully the name alone is a good enough warning. Here is how I would do it using unsafe:

buf := new(bytes.Buffer)
buf.ReadFrom(yourReader)
b := buf.Bytes()
s := *(*string)(unsafe.Pointer(&b))

There we go, you have now efficiently converted your byte array to a string. Really, all this does is trick the type system into calling it a string. There are a couple caveats to this method:

1. There are no guarantees this will work in all go compilers. While this works with the plan-9 gc compiler, it relies on "implementation details" not mentioned in the official spec. You can not even guarantee that this will work on all architectures or not be changed in gc. In other words, this is a bad idea.
2. That string is mutable! If you make any calls on that buffer it will change the string. Be very careful.

My advice is to stick to the official method. Doing a copy is not that expensive and it is not worth the evils of unsafe. If the string is too large to do a copy, you should not be making it into a string.

I had the same issue on macOS, after some time struggling and searching around, this answer actually solved the issue for me:

npm config rm proxy
npm config rm https-proxy
npm config set registry http://registry.npmjs.org/

SourceForge uses MongoDB. See this presentation or read here.

This works for me:

@Transactional
public void remove(Integer groupId) {
    Group group = groupRepository.findOne(groupId);
    group.getUsers().removeAll(group.getUsers());

    // Other business logic

    groupRepository.delete(group);
}

Also, mark the method @Transactional (org.springframework.transaction.annotation.Transactional), this will do whole process in one session, saves some time.

In addition to others' answers :

static:: will be computed using runtime information.

That means you can't use static:: in a class property because properties values :

Must be able to be evaluated at compile time and must not depend on run-time information.

class Foo {
    public $name = static::class;

}

$Foo = new Foo;
echo $Foo->name; // Fatal error

Using self::

class Foo {
    public $name = self::class;

}
$Foo = new Foo;
echo $Foo->name; // Foo

Please note that the Fatal error comment in the code i made doesn't indicate where the error happened, the error happened earlier before the object was instantiated as @Grapestain mentioned in the comments

You can also use pythonlangutil:

from pythonlangutil.overload import Overload, signature

class A:
    @Overload
    @signature()
    def stackoverflow(self):    
        print 'first method'

    @stackoverflow.overload
    @signature("int")
    def stackoverflow(self, i):
        print 'second method', i

Late to the conversation...

But, why not use css? That way you can keep the button as a submit type.

html:

<input type="submit" value="go" />

css:

button, input[type="submit"] {
    background:url(/images/submit.png) no-repeat;"
}

Works like a charm.

EDIT: If you want to remove the default button styles, you can use the following css:

button, input[type="submit"]{
    color: inherit;
    border: none;
    padding: 0;
    font: inherit;
    cursor: pointer;
    outline: inherit;
}

from this SO question

There's also some good discussion about this here: Is this the proper use of a mutex?

If you just get rid of everything (e.g. if you are in tests)

org.apache.log4j.BasicConfigurator.configure(new NullAppender());

I found a neat solution to get to result:

Suppose you have an model object o:

Just call:

type(o).objects.filter(pk=o.pk).values().first()

If the problem is to find whether the phone's network is connected and fast enough to meet your demands you have to handle all the network types returned by getSubType().

It took me an hour or two to research and write this class to do just exactly that, and I thought I would share it with others that might find it useful.

Here is a Gist of the class, so you can fork it and edited it.

You cannot use Set Transaction Isolation Level Read Uncommitted in a View (you can only have one script in there in fact), so you would have to use (nolock) if dirty rows should be included.

<script type="text/javascript">
  var timeout = setTimeout("location.reload(true);",600000);
  function resetTimeout() {
    clearTimeout(timeout);
    timeout = setTimeout("location.reload(true);",600000);
  }
</script>

Above will refresh the page every 10 minutes unless resetTimeout() is called. For example:

<a href="javascript:;" onclick="resetTimeout();">clicky</a>

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

I'm using Visual Studio Professional licensed over the MAPS Action Pack subscription. Since the new version of the Microsoft Partner Center one have to add the subscribed user to the partner benefit software.

Partner Center->Benefits->Visual Studio Subscriptions->Add user

After that one have to sign out and reenter the credentials in the account settings of VS.

Use \t and enclose the string with double-quotes:

$chunk = "abc\tdef\tghi";

Try the JavaScript in operator.

if ('key' in myObj)

And the inverse.

if (!('key' in myObj))

Be careful! The in operator matches all object keys, including those in the object's prototype chain.

Use myObj.hasOwnProperty('key') to check an object's own keys and will only return true if key is available on myObj directly:

myObj.hasOwnProperty('key')

Unless you have a specific reason to use the in operator, using myObj.hasOwnProperty('key') produces the result most code is looking for.

The reply by Phil Sacre was correct however the session shouldn't be used just for the hell of it. You should only use this for values which really need to live for the lifetime of the session, such as a user login. It's common to see people overuse the session and run into more issues, especially when dealing with a collection or when users return to a page they previously visited only to find they have values still remaining from a previous visit. A smart program minimizes the scope of variables as much as possible, a bad one uses session too much.

I fixed an error like this changing the places of the routes in routes.php, for example i had something like this:

Route::resource('Mensajes', 'MensajeriaController');
Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');

and then I put it like this:

Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');
Route::resource('Mensajes', 'MensajeriaController');

If these are MyISAM tables, then plopping the .FRM, .MYD, and .MYI files into a database directory (e.g., /var/lib/mysql/dbname) will make that table available. It doesn't have to be the same database as they came from, the same server, the same MySQL version, or the same architecture. You may also need to change ownership for the folder (e.g., chown -R mysql:mysql /var/lib/mysql/dbname)

Note that permissions (GRANT, etc.) are part of the mysql database. So they won't be restored along with the tables; you may need to run the appropriate GRANT statements to create users, give access, etc. (Restoring the mysql database is possible, but you need to be careful with MySQL versions and any needed runs of the mysql_upgrade utility.)

Actually, you probably just need the .FRM (table structure) and .MYD (table data), but you'll have to repair table to rebuild the .MYI (indexes).

The only constraint is that if you're downgrading, you'd best check the release notes (and probably run repair table). Newer MySQL versions add features, of course.

[Although it should be obvious, if you mix and match tables, the integrity of relationships between those tables is your problem; MySQL won't care, but your application and your users may. Also, this method does not work at all for InnoDB tables. Only MyISAM, but considering the files you have, you have MyISAM]

I'm not very advanced in AngularJS, but my solution would be to use a simple JS class for you cart (in the sense of coffee script) that extend Array.

The beauty of AngularJS is that you can pass you "model" object with ng-click like shown below.

I don't understand the advantage of using a factory, as I find it less pretty that a CoffeeScript class.

My solution could be transformed in a Service, for reusable purpose. But otherwise I don't see any advantage of using tools like factory or service.

class Basket extends Array
  constructor: ->

  add: (item) ->
    @push(item)

  remove: (item) ->
    index = @indexOf(item)
    @.splice(index, 1)

  contains: (item) ->
    @indexOf(item) isnt -1

  indexOf: (item) ->
    indexOf = -1
    @.forEach (stored_item, index) ->
      if (item.id is stored_item.id)
        indexOf = index
    return indexOf

Then you initialize this in your controller and create a function for that action:

 $scope.basket = new Basket()
 $scope.addItemToBasket = (item) ->
   $scope.basket.add(item)

Finally you set up a ng-click to an anchor, here you pass your object (retreived from the database as JSON object) to the function:

li ng-repeat="item in items"
  a href="#" ng-click="addItemToBasket(item)" 

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__)) 

Assuming that you want to get a value from the user input in html textbox whenever the user clicks 'Click' button, and then call a python function (mypythonfunction) that you wrote inside mypythoncode.py. Note that "btn" class is defined in a css file.

inside templateHTML.html:

<form action="#" method="get">
 <input type="text" value="8" name="mytextbox" size="1"/>
 <input type="submit" class="btn" value="Click" name="mybtn">
</form>

inside view.py:

import mypythoncode

def request_page(request):
  if(request.GET.get('mybtn')):
    mypythoncode.mypythonfunction( int(request.GET.get('mytextbox')) )
return render(request,'myApp/templateHTML.html')

Let me share what I end up with, which allows to set correctly width or height by getting the image dimensions. In addition, the code allows to fetch a loading image while the large image data we need is being transfered:

1. Use static method Image.prefetch to have the image downloaded and available to cache.

2. Use static method Image.getSize to collect height and width and use it to compute an aspect ratio and then the final height (or width)

3. Display image with a default style to your prefered width (The height will be computed with aspect ratio kept)

    function ImageX(props: {source: string, id: string})
    {
      const [imageHeight, setImageHeight] = React.useState(1);
      Image.prefetch(props.source)
      .then(() => {
          Image.getSize(props.source, (width, height) => {
            let aspectRatio =  height/width;
            setImageHeight(aspectRatio*Dimensions.get('window').width);
          });
      })
      .catch(error => console.log(error))
      if (imageHeight <=1) //Image not in cache (disk) yet
        {
          return (
            <Image key={props.id} style={styleimg.image} source={{uri: 'http://www.dsdsd/loaderpreview.gif'}}/>
          );
      }
      else
      {
        return (
          <Image key={props.id} style={styleimg.image} height={imageHeight} source={{uri: props.source}}/>
        );
      }
    }
   

   const styleimg = StyleSheet.create({ image: { width: Dimensions.get('window').width, resizeMode: 'contain' //... // you can set a height defaults } });

Use : instead of =

see the example below that gives an error

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name = filter.clean(req.body.name.toString()),
        content = filter.clean(req.body.content.toString()),
        created: new Date()
    };

That gives Syntex Error: invalid shorthand proprty initializer.

Then i replace = with : that's solve this error.

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name: filter.clean(req.body.name.toString()),
        content: filter.clean(req.body.content.toString()),
        created: new Date()
    };

Assuming you are on Python 3, you can use this syntax

inputs = list(map(str,input().split()))

if you want to access individual element you can do it like that

m, n = map(str,input().split())

Yes I think this would be quicker.

Get-ChildItem $folder | Sort-Object -Descending -Property LastWriteTime -Top 1 

You can use the HTMLOptionsCollection.namedItem() That means that you have to define your select options to have a name attribute and have the value of the displayed text. e.g California

For older versions of windows (2k, 2k3, xp)

Java 6 has a default embedded http server.

By the way, if you plan to have a rest web service, here is a simple example using jersey.

As far as I'm concerned the best solution is using GetValueOrDefault() method.

v2 = v1.GetValueOrDefault();

In the case of SVG images inlined in the page there is another important issue that arises when the base tag is used:

Since with the base tag (as noted above already) you effectively loose the ability to use relative hash URLs like in

<a href="#foo">

because they will be resolved against the base URL rather than the current document's location and thus are not relative anymore. So you will have to add the path of the current document to these kinds of links like in

<a href="/path/to/this/page/name.html#foo">

So one of the seemingly positive aspects of the base tag (which is to move the long URL prefixes away from the anchor tag and get nicer, shorter anchors) completely backfires for local hash URLs.

This is especially annoying when inlining SVG in your page, be it static SVG or dynamically generated SVG because in SVG there can be a lot of such references and they will all break as soon as a base tag is used, on most, but not all user agent implementations (Chrome at least still works in these scenarios at the time of writing).

If you are using a templating system or another tool-chain that processes/generates your pages, I would always try to get rid of the base tag, because as I see it, it brings more problems to the table than it solves.

If you just want to make them black in Bootstrap 4+.

.carousel-control-next,
.carousel-control-prev /*, .carousel-indicators */ {
    filter: invert(100%);
}

According to Html5 specs you should use -- element.options[e.selectedIndex].text

e.g. if you have select box like below :

<select id="selectbox1">
    <option value="1">First</option>
    <option value="2" selected="selected">Second</option>
    <option value="3">Third</option>
</select>
<br/>
<button onClick="GetItemValue('selectbox1');">Get Item</button>

you can get value using following script :

<script>
 function GetItemValue(q) {
   var e = document.getElementById(q);
   var selValue = e.options[e.selectedIndex].text ;
   alert("Selected Value: "+selValue);
 }
</script>

Tried and tested.

Try using the following on the JavaScript side:

window.location.href = '@Url.Action("Index", "Controller")';

If you want to pass parameters to the @Url.Action, you can do this:

var reportDate = $("#inputDateId").val();//parameter
var url = '@Url.Action("Index", "Controller", new {dateRequested = "findme"})';
window.location.href = url.replace('findme', reportDate);

In one line:

String date=new SimpleDateFormat("MM-dd-yyyy").format(new SimpleDateFormat("yyyy-MM-dd").parse("2011-01-01"));

Where:

String date=new SimpleDateFormat("FinalFormat").format(new SimpleDateFormat("InitialFormat").parse("StringDate"));

It's possible to have normal getter/setter pair. You just need to specify access mode in @JsonProperty

Here is unit test for that:

public class JsonPropertyTest {

  private static class TestJackson {

    private String color;

    @JsonProperty(value = "device_color", access = JsonProperty.Access.READ_ONLY)
    public String getColor() {
      return color;
    };

    @JsonProperty(value = "color", access = JsonProperty.Access.WRITE_ONLY)
    public void setColor(String color) {
      this.color = color;
    }

  }

  @Test
  public void shouldParseWithAccessModeSpecified() throws Exception {
    String colorJson = "{\"color\":\"red\"}";
    ObjectMapper mapper = new ObjectMapper();
    TestJackson colotObject = mapper.readValue(colorJson, TestJackson.class);

    String ser = mapper.writeValueAsString(colotObject);
    System.out.println("Serialized colotObject: " + ser);
  }
}

I got the output as follows:

Serialized colotObject: {"device_color":"red"}

I just modified your code. It works fine in my system. See if this helps

class round{
    public static void main(String args[]){

    double a = 123.13698;
    double roundOff = Math.round(a*100)/100.00;

    System.out.println(roundOff);
}
}

Most of the time the solution for this error is really simple:

1. Uninstall your apk
2. Clean your Android project
3. Build your Android project
4. Install / run your apk

If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'port';


mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)

It will give you the port number on which MySQL is running.

If you want to know the hostname of your Mysql you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'hostname';


mysql> SHOW VARIABLES WHERE Variable_name = 'hostname';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| hostname          | Dell  |
+-------------------+-------+
1 row in set (0.00 sec)

It will give you the hostname for mysql.

If you want to know the username of your Mysql you can use this query on MySQL Command line client --

select user();

In addition to accepted answer, if you're using Entity Migrations for updating database, you should add this line at the beggining of the Up() function in your migration file:

Sql("alter table dbo.CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];");

You can find the constraint name in the error at nuget packet manager console which starts with FK_dbo.

$client = new \GuzzleHttp\Client(['base_uri' => 'http://example.com/api']);

$response = $client->post('/save', [
    'json' => [
        'name' => 'John Doe'
    ]
]);

return $response->getBody();

Unfortunately, at the time of writing this answer, there is no direct way to do this. You need to:

1. use a semi-transparent image for background (much easier).
2. add an extra element (like div) next to children which you want the opaque, add background to it and after making it semi-transparent, position it behind mentioned children.

You can store virtually any object using a Django Pickle Field, ala this snippet:

POJO: If the class can be executed with underlying JDK,without any other external third party libraries support then its called POJO

JavaBean: If class only contains attributes with accessors(setters and getters) those are called javabeans.Java beans generally will not contain any bussiness logic rather those are used for holding some data in it.

All Javabeans are POJOs but all POJO are not Javabeans

in some cases you might need an override of onLoadResource if you get a redirect which doesn't trigger the url loading method. in this case i tried the following:

@Override
public void onLoadResource(WebView view, String url)
{
    if (url.equals("http://redirectexample.com"))
    {
        //do your own thing here
    }
    else
    {
        super.onLoadResource(view, url);
    }           
}

There is a proper way to split the filename and the extension: Extract filename and extension in Bash

You can apply it like this:

date=$(date +"%m%d%y")
for FILE in folder1/*.csv
do
    bname=$(basename "$FILE")
    extension="${bname##*.}"
    filenamewoext="${bname%.*}"
    newfilename="${filenamewoext}${date}.${extension}
    cp folder1/${FILE} folder2/${newfilename}
done

Personally, I found that by opening cmd as admin then run python -m pip install mitproxy seems to fix my problem.

Note:- I installed python through chocolatey

SSLSHopper has some pretty thorough articles about moving between different servers.

http://www.sslshopper.com/how-to-move-or-copy-an-ssl-certificate-from-one-server-to-another.html

Just pick the relevant link at bottom of this page.

Note: they have an online converter which gives them access to your private key. They can probably be trusted but it would be better to use the OPENSSL command (also shown on this site) to keep the private key private on your own machine.

You could install Charles - an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet - on your PC or MAC.

Config steps:

• Let your phone and PC or MAC in a same LAN
• Launch Charles which you installed (default proxy port is 8888)
• Setup your phone's wifi configuration: set the ip of delegate to your PC or MAC's ip, port of delegate to 8888
• Lauch your app in your phone. And monitor http requests on Charles.

You need to add a break statement:

switch (searchType)
{
case "SearchBooks":
    Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
    break;
case "SearchAuthors":
    Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
    break;
}

This assumes that you want to either handle the SearchBooks case or the SearchAuthors - as you had written in, in a traditional C-style switch statement the control flow would have "fallen through" from one case statement to the next meaning that all 4 lines of code get executed in the case where searchType == "SearchBooks".

The compiler error you are seeing was introduced (at least in part) to warn the programmer of this potential error.

As an alternative you could have thrown an error or returned from a method.

yes you can use custom font in your application

step by step following there:

• Add your custom font files into your project in supporting files
• Add a key to your Info.plist file called UIAppFonts.
• Make this key an array
• For each font you have, enter the full name of your font file (including the extension) as items to the UIAppFonts array
• Save Info.plist Now in your application you can simply call [UIFont fontWithName:@"your Custom font Name" size:20] to get the custom font to use with your UILabels

after applying this if your not getting correct font then you double click on the custom font , and see carefully top side font name is comming and copy this font , paste, here [UIFont fontWithName:@" here past your Custom font Name" size:20] i hope you will get correct answer

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

-----BEGIN PUBLIC KEY-----

Try this-

driver.findElement(By.name("period")).sendKeys("Last 52 Weeks");

You could do something like

Move uncommited changes to a new branch

I created a .gitconfig alias for this:

[alias]
spcosp = !"git stash push && git checkout \"$@\" && git stash pop --index #"

To change to new-branch-name, use:

git spcosp new-branch-name

And any non-commited file and index changes will be kept.

interface:

In general, an interface exposes a contract without exposing the underlying implementation details. In Object Oriented Programming, interfaces define abstract types that expose behavior, but contain no logic. Implementation is defined by the class or type that implements the interface.

@interface : (Annotation type)

Take the below example, which has a lot of comments:

public class Generation3List extends Generation2List {

   // Author: John Doe
   // Date: 3/17/2002
   // Current revision: 6
   // Last modified: 4/12/2004
   // By: Jane Doe
   // Reviewers: Alice, Bill, Cindy

   // class code goes here

}

Instead of this, you can declare an annotation type

 @interface ClassPreamble {
   String author();
   String date();
   int currentRevision() default 1;
   String lastModified() default "N/A";
   String lastModifiedBy() default "N/A";
   // Note use of array
   String[] reviewers();
}

which can then annotate a class as follows:

@ClassPreamble (
   author = "John Doe",
   date = "3/17/2002",
   currentRevision = 6,
   lastModified = "4/12/2004",
   lastModifiedBy = "Jane Doe",
   // Note array notation
   reviewers = {"Alice", "Bob", "Cindy"}
)
public class Generation3List extends Generation2List {

// class code goes here

}

PS: Many annotations replace comments in code.

Reference: http://docs.oracle.com/javase/tutorial/java/annotations/declaring.html

                var oldTitle = document.title;
                var msg = "New Popup!";
                var timeoutId = false;

                var blink = function() {
                    document.title = document.title == msg ? oldTitle : msg;//Modify Title in case a popup

                    if(document.hasFocus())//Stop blinking and restore the Application Title
                    {
                        document.title = oldTitle;
                        clearInterval(timeoutId);
                    }                       
                };

                if (!timeoutId) {
                    timeoutId = setInterval(blink, 500);//Initiate the Blink Call
                };//Blink logic 

Tested this on a CentOS VMWare image that I keep around for this sort of thing. Note that you probably want to avoid putting passwords as command-line arguments, because anybody on the entire machine can read them out of 'ps -ef'.

That said, this will work:

user="$1"
password="$2"
adduser $user
echo $password | passwd --stdin $user

Found it!

SELECT username, 
       account_status
  FROM dba_users;

datagridview.rows[index].cells[1].value=1;
datagridview.rows[index].cells[2].value="a";
datagridview.rows[index].cells[3].value="b";

hope this help! :)

The problem with all these answers is that they do not take virtual directories into account.

Consider:

Site named "tempuri.com/" rooted at c:\domains\site
virtual directory "~/files" at c:\data\files
virtual directory "~/files/vip" at c:\data\VIPcust\files

So:

Server.MapPath("~/files/vip/readme.txt") 
  = "c:\data\VIPcust\files\readme.txt"

But there is no way to do this:

MagicResolve("c:\data\VIPcust\files\readme.txt") 
   = "http://tempuri.com/files/vip/readme.txt"

because there is no way to get a complete list of virtual directories.

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

Just wanted to add to this, you can have the :not selector in oldIE using selectivizr: http://selectivizr.com/

If you don't know which checkboxes your page has (ex: if you are creating them dynamically) you can simply put a hidden field with the same name and 0 value right above the checkbox.

<input type="hidden" name="foo" value="0" />
<input type="checkbox" name="foo" value="1">

This way you will get 1 or 0 based on whether the checkbox is selected or not.

Slightly more than just displaying the function, how about getting the edit in-place facility as well.

\ef <function_name> is very handy. It will open the source code of the function in editable format. You will not only be able to view it, you can edit and execute it as well.

Just \ef without function_name will open editable CREATE FUNCTION template.

window.location.reload(true) seems to have been deprecated by the HTML5 standard. One way to do this without using query strings is to use the Clear-Site-Data header, which seems to being standardized.

One of the best examples of Hadoop-like MapReduce implementation.

Keep in mind though that they are limited to key-value based implementations of the MapReduce idea (so they are limiting in applicability).

The following categories of variables are classified as initially unassigned:

• Instance variables of initially unassigned struct variables.
• Output parameters, including the this variable of struct instance constructors.
• Local variables , except those declared in a catch clause or a foreach statement.

The following categories of variables are classified as initially assigned:

• Static variables.
