Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

After exiting eclipse I moved .eclipse (found in the user's home directory) to .eclipse.old (just in case I may have had to undo). The error does not show up any more and my projects are working fine after restarting eclipse.

Caution: I have a simple setup and this may not be the best for environments with advanced settings.

I am posting this as a separate answer as previously listed methods did not work for me.

This error basically happens when the specific port is not free. So there are two solutions, you can free that port by killing or closing the service which is using it or you can run your application (tomcat) on a different port.

Solution 1: Free the port

On a Linux machine you can find the process-id of port's consumer and then kill it. Use the following command (it is assume that the default port is 8080)

netstat -pnltu | grep -i "8080"

The output of the above-mentioned command would be something like:

tcp6   0  0 :::8080    :::*      LISTEN      20674/java 

Then you can easily kill the process with its processid:

kill 20674

On a windows machine to find a processid use netstat -ano -p tcp |find "8080". To kill the process use taskkill /F /PID 1234 (instead of 1234 enter the founded processid).

Solution 2: Change the default port

In the development process developers use the port 8080 that you can change it easily. You need to specify your desired port number in the application.properties file of your project (/src/main/resources/application.properties) by using the following specification:

server.port=8081

You can also set an alternative port number while executing the .jar file

- java -jar spring-boot-application.jar --server.port=8081

Please notice that sometimes (not necessarily) you have to change other ports too like:

management.port=
tomcat.jvmroute=
tomcat.ajp.port=
tomcat.ajp.redirectPort=
etc...

I tried the option above of moving the plugins but it didn't work. My solution was to delete the entire .metadata folder. This meant that I lost my defaults and had to import my projects again.

The solution is to set the proxy to "native" as below

Go to "Window-> Preferences -> General -> Network Connection" and change the Settings "Active Provider-> Native". It worked for me.

There are several methods of showing a progress bar (circle) while loading an activity. In your case, one with a ListView in it.

IN ACTIONBAR

If you are using an ActionBar, you can call the ProgressBar like this (this could go in your onCreate()

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  
setProgressBarIndeterminateVisibility(true);

And after you are done displaying the list, to hide it.

setProgressBarIndeterminateVisibility(false);

IN THE LAYOUT (The XML)

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/linlaHeaderProgress"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:visibility="gone" >

        <ProgressBar
            android:id="@+id/pbHeaderProgress"
            style="@style/Spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >
        </ProgressBar>
    </LinearLayout>

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:cacheColorHint="@android:color/transparent"
        android:divider="#00000000"
        android:dividerHeight="0dp"
        android:fadingEdge="none"
        android:persistentDrawingCache="scrolling"
        android:smoothScrollbar="false" >
    </ListView>
</LinearLayout>

And in your activity (Java) I use an AsyncTask to fetch data for my lists. SO, in the AsyncTask's onPreExecute() I use something like this:

// CAST THE LINEARLAYOUT HOLDING THE MAIN PROGRESS (SPINNER)
LinearLayout linlaHeaderProgress = (LinearLayout) findViewById(R.id.linlaHeaderProgress);

@Override
protected void onPreExecute() {    
    // SHOW THE SPINNER WHILE LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.VISIBLE);
}

and in the onPostExecute(), after setting the adapter to the ListView:

@Override
protected void onPostExecute(Void result) {     
    // SET THE ADAPTER TO THE LISTVIEW
    lv.setAdapter(adapter);

    // CHANGE THE LOADINGMORE STATUS TO PERMIT FETCHING MORE DATA
    loadingMore = false;

    // HIDE THE SPINNER AFTER LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.GONE);
}

EDIT: This is how it looks in my app while loading one of several ListViews

I just replaced the swt.jar in my package with the 64bit version and it worked straight away. No need to recompile the whole package, just replace the swt.jar file and make sure your application manifest includes it.

On redhat7 :

yum install gtk2 libXtst xorg-x11-fonts-Type1

did the job, because of a swt dependency.

found here

You can get this if the client specifies "https" but the server is only running "http". So, the server isn't expecting to make a secure connection.

In my case I had a Kotlin class with some fields which were not open so the generated Java setters and getters would be final. Solved it by adding open keyword to each field.

Before:

open class User(
    var id: String = "",
    var email: String = ""
)

After:

open class User(
    open var id: String = "",
    open var email: String = ""
)

You need to tell SQLPlus which database you want to log on to. Host String needs to be either a connection string or an alias configured in your TNSNames.ora file.

Sometimes, the previously installed version is cached.

~$ pip install pillow==5.2.0

It returns the followings:
Requirement already satisfied: pillow==5.2.0 in /home/ubuntu/anaconda3/lib/python3.6/site-packages (5.2.0)

We can use --no-cache-dir together with -I to overwrite this

~$ pip install --no-cache-dir -I pillow==5.2.0

check jar files in your project which are mentioned in config.ini if not proper then install manually and then follow the following steps:

1. Select your product configuration file, right-click on it and select Run As Run Configurations
2. Select "Validate plug-ins prior to launching". This will check if you have all required plug-ins in your run configuration. If this check reports that some plug-ins are missing, try clicking the "Add Required-Plug-Ins" button. Also make sure to define all dependencies in your product. And your application start running

The /configuration/config.ini file should contain org.eclipse.core.runtime@start in the commaseparated osgi.bundles property. Here is the default osgi.bundles property, maybe it was (accidently) changed during some upgrade:

osgi.bundles=org.eclipse.equinox.common@2:start,org.eclipse.update.configurator@3:start,org.eclipse.core.runtime@start

You can if necessary override it by setting it as VM argument in /eclipse.ini:

-Dosgi.bundles=org.eclipse.equinox.common@2:start,org.eclipse.update.configurator@3:start,org.eclipse.core.runtime@start

SET NOCOUNT ON; Above code will stop the message generated by sql server engine to fronted result window after the DML/DDL command execution.

Why we do it? As SQL server engine takes some resource to get the status and generate the message, it is considered as overload to the Sql server engine.So we set the noncount message on.

If you do not want your application to terminate when a JFrame is closed, use: setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE)

instead of: setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

From the documentation:

DO_NOTHING_ON_CLOSE (defined in WindowConstants): Don't do anything; require the program to handle the operation in the windowClosing method of a registered WindowListener object.

HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the frame after invoking any registered WindowListener objects.

DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the frame after invoking any registered WindowListener objects.

EXIT_ON_CLOSE (defined in JFrame): Exit the application using the System exit method. Use this only in applications.

might still be useful: You can use setVisible(false) on your JFrame if you want to display the same frame again. Otherwise call dispose() to remove all of the native screen resources.

This can occur when the workbook is password-protected. There are some workarounds to remove this protection but most of the examples you'll find online are outdated. Either way, the simple solution is to unprotect the workbook manually, otherwise use something like OpenXML to remove the protection programmatically.

Use f-string:

print(f'Total score for {name} is {score}')

Or

Use .format:

print("Total score for {} is {}".format(name, score))

As of mid-2015, I believe this is the best solution:

<input type="number" pattern="[0-9]*" inputmode="numeric">

This will give you the numeric keypad on both Android and iOS:

It also gives you the expected desktop behavior with the up/down arrow buttons and keyboard friendly up/down arrow key incrementing:

Try it in this code snippet:

<form>_x000D_
  <input type="number" pattern="[0-9]*" inputmode="numeric">_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

By combining both type="number" and pattern="[0-9]*, we get a solution that works everywhere. And, its forward compatible with the future HTML 5.1 proposed inputmode attribute.

Note: Using a pattern will trigger the browser's native form validation. You can disable this using the novalidate attribute, or you can customize the error message for a failed validation using the title attribute.

If you need to be able to enter leading zeros, commas, or letters - for example, international postal codes - check out this slight variant.

Need to convert it in base64.

JS have btoa() function for it.

For example:

var img = document.createElement('img');
img.src = 'data:image/jpeg;base64,' + btoa('your-binary-data');
document.body.appendChild(img);

But i think what your binary data in pastebin is invalid - the jpeg data must be ended on 'ffd9'.

Update:

Need to write simple hex to base64 converter:

function hexToBase64(str) {
    return btoa(String.fromCharCode.apply(null, str.replace(/\r|\n/g, "").replace(/([\da-fA-F]{2}) ?/g, "0x$1 ").replace(/ +$/, "").split(" ")));
}

And use it:

img.src = 'data:image/jpeg;base64,' + hexToBase64('your-binary-data');

See working example with your hex data on jsfiddle

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

There is no standardized way to do that. For windows the functionality is provided in the DbgHelp library

I am not sure if you have edited right configuration file. Try following steps

1. open %userprofile%\ducuments\iisexpress\config\applicationhost.config

2. By default bellow given entries are commented in the applicationhost.config file. uncomment these entries.

<add name="WebDAVModule" image="%IIS_BIN%\webdav.dll" />


<add name="WebDAVModule" />

<add name="WebDAV" path="*"
 verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK"
 modules="WebDAVModule" resourceType="Unspecified" requireAccess="None"
 />

openFileInput() doesn't accept paths, only a file name if you want to access a path, use File file = new File(path) and corresponding FileInputStream

For those trying to get this to work in iOS 8, the "Apple-approved" way to display a transparent modal view controller is by setting modalPresentationStyle on the presented controller to UIModalPresentationOverCurrentContext.

This can be done in code, or by setting the properties of the segue in the storyboard.

From the UIViewController documentation:

UIModalPresentationOverCurrentContext

A presentation style where the content is displayed over only the parent view controller’s content. The views beneath the presented content are not removed from the view hierarchy when the presentation finishes. So if the presented view controller does not fill the screen with opaque content, the underlying content shows through.

When presenting a view controller in a popover, this presentation style is supported only if the transition style is UIModalTransitionStyleCoverVertical. Attempting to use a different transition style triggers an exception. However, you may use other transition styles (except the partial curl transition) if the parent view controller is not in a popover.

Available in iOS 8.0 and later.

https://developer.apple.com/documentation/uikit/uiviewcontroller

The 'View Controller Advancements in iOS 8' video from WWDC 2014 goes into this in some detail.

Note:

• Be sure to give your presented view controller a clear background color, lest it not actually be see-through!
• You have to set this before presenting ie setting this parameter in the viewDidLoad of the presentedViewController won't have any affect

I know this already has a marked answer, but I feel I have an improvement to it.

The marked answer is a bit misleading. He set a width to the button, which is not necessary, and set widths are not "responsive". To his defense, he mentions in a comment below it, that the width is not necessary and just an example.

One thing not mentioned here, is that the words may break in the middle of a word and look messed up.

My solution, forces the break to happen between words, a nice word wrap.

.btn-responsive {
    white-space: normal !important;
    word-wrap: break-word;
}

<a href="#" class="btn btn-primary btn-responsive">Click Here</a>

Yes, you can dynamically set the position of the view in Android. Likewise, you have an ImageView in LinearLayout of your XML file. So you can set its position through LayoutParams.But make sure to take LayoutParams according to the layout taken in your XML file. There are different LayoutParams according to the layout taken.

Here is the code to set:

    LayoutParams layoutParams=new LayoutParams(int width, int height);
    layoutParams.setMargins(int left, int top, int right, int bottom);
    imageView.setLayoutParams(layoutParams);

You can enable the CURLOPT_VERBOSE option:

curl_setopt($curlhandle, CURLOPT_VERBOSE, true);

When CURLOPT_VERBOSE is set, output is written to STDERR or the file specified using CURLOPT_STDERR. The output is very informative.

You can also use tcpdump or wireshark to watch the network traffic.

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

I know this is an old post, but for anyone using Retrofit, this can be useful useful.

If you are using Retrofit + Jackson + Kotlin + Data classes, you need:

1. add implement group: 'com.fasterxml.jackson.module', name: 'jackson-module-kotlin', version: '2.7.1-2' to your dependencies, so that Jackson can de-serialize into Data classes
2. When building retrofit, pass the Kotlin Jackson Mapper, so that Retrofit uses the correct mapper, ex:

    val jsonMapper = com.fasterxml.jackson.module.kotlin.jacksonObjectMapper()

    val retrofit = Retrofit.Builder()
          ...
          .addConverterFactory(JacksonConverterFactory.create(jsonMapper))
          .build()

Note: If Retrofit is not being used, @Jayson Minard has a more general approach answer.

I have seen people use Throwable to catch some errors that might happen due to infra failure/ non availability.

Here is an option using a for loop by groups rather by rows (like OP did)

for (i in unique(df$cat)) df$num[df$cat == i] <- seq_len(sum(df$cat == i))

Changing the ramSize in config.ini file didnt work for me.

I changed the SD Card size to 1000 MiB in Edit Android Virtual Device window ...It worked! :)

I'm going to assume you do not want to count hidden or system files.

There are many ways to do this. All of the methods that I will show involve some form of the FOR command. There are many variations of the FOR command that look almost the same, but they behave very differently. It can be confusing for a beginner.

You can get help by typing HELP FOR or FOR /? from the command line. But that help is a bit cryptic if you are not used to reading it.

1) The DIR command lists the number of files in the directory. You can pipe the results of DIR to FIND to get the relevant line and then use FOR /F to parse the desired value from the line. The problem with this technique is the string you search for has to change depending on the language used by the operating system.

@echo off
for /f %%A in ('dir ^| find "File(s)"') do set cnt=%%A
echo File count = %cnt%

2) You can use DIR /B /A-D-H-S to list the non-hidden/non-system files without other info, pipe the result to FIND to count the number of files, and use FOR /F to read the result.

@echo off
for /f %%A in ('dir /a-d-s-h /b ^| find /v /c ""') do set cnt=%%A
echo File count = %cnt%

3) You can use a simple FOR to enumerate all the files and SET /A to increment a counter for each file found.

@echo off
set cnt=0
for %%A in (*) do set /a cnt+=1
echo File count = %cnt%

You can use pytz as well..

import datetime
import pytz
def utcnow():
    return datetime.datetime.now(tz=pytz.utc)
utcnow()
   datetime.datetime(2020, 8, 15, 14, 45, 19, 182703, tzinfo=<UTC>)
utcnow().isoformat()

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

function GetURLParameter(parameter) {
        var url;
        var search;
        var parsed;
        var count;
        var loop;
        var searchPhrase;
        url = window.location.href;
        search = url.indexOf("?");
        if (search < 0) {
            return "";
        }
        searchPhrase = parameter + "=";
        parsed = url.substr(search+1).split("&");
        count = parsed.length;
        for(loop=0;loop<count;loop++) {
            if (parsed[loop].substr(0,searchPhrase.length)==searchPhrase) {
                return decodeURI(parsed[loop].substr(searchPhrase.length));
            }
        }
        return "";
    }

Use this

dataTable.Columns["OldColumnName"].ColumnName = "NewColumnName";

For what it's worth: I just had the same problem, after editing the nginx.conf file. I tried and tried restarting it by commanding sudo nginx restart and various other commands. None of them produced any output. Commanding sudo nginx -t to check the configuration file gave the output sudo: nginx: command not found, which was puzzling. I was starting to think there were problems with the path.

Finally, I logged in as root (sudo su) and commanded sudo nginx restart. Now, the command displayed an error message concerning the configuration file. After fixing that, it restarted successfully.

Apply DataAnnotation like:

[DisplayFormat(DataFormatString = "{0:MMM dd, yyyy}")]

Try this Swift code in a UIViewController -

func doAlertControllerDemo() {

    var inputTextField: UITextField?;

    let passwordPrompt = UIAlertController(title: "Enter Password", message: "You have selected to enter your passwod.", preferredStyle: UIAlertControllerStyle.Alert);

    passwordPrompt.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: { (action) -> Void in
        // Now do whatever you want with inputTextField (remember to unwrap the optional)

        let entryStr : String = (inputTextField?.text)! ;

        print("BOOM! I received '\(entryStr)'");

        self.doAlertViewDemo(); //do again!
    }));


    passwordPrompt.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler: { (action) -> Void in
        print("done");
    }));


    passwordPrompt.addTextFieldWithConfigurationHandler({(textField: UITextField!) in
        textField.placeholder = "Password"
        textField.secureTextEntry = false       /* true here for pswd entry */
        inputTextField = textField
    });


    self.presentViewController(passwordPrompt, animated: true, completion: nil);


    return;
}

Change position:absolute; to position:fixed;

If you are using lodash or npm, use lodash's merge function to deep copy all of the object's properties to a new empty object like so:

var objectCopy = lodash.merge({}, originalObject);

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

You can directly add a constraint for table

ALTER TABLE TableName
ADD CONSTRAINT ConstraintName PRIMARY KEY(ColumnName)
GO 

Make sure your primary key column should not have any null values.

Option 2:

you can change your SQL Management Studio Options like

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

This is the simplest way of printing the internal binary representation of an integer. For Example: If we take n as 17 then the output will be: 0000 0000 0000 0000 0000 0000 0001 0001

void bitPattern(int n) {

        int mask = 1 << 31;
        int count = 0;
        while(mask != 0) {
            if(count%4 == 0)
                System.out.print(" ");

            if((mask&n) == 0) 

                System.out.print("0");



            else 
                System.out.print("1");


            count++;
            mask = mask >>> 1;


    }
    System.out.println();
}

Fast and simple Javascript image resizer:

https://github.com/calvintwr/blitz-hermite-resize

const blitz = Blitz.create()

/* Promise */
blitz({
    source: DOM Image/DOM Canvas/jQuery/DataURL/File,
    width: 400,
    height: 600
}).then(output => {
    // handle output
})catch(error => {
    // handle error
})

/* Await */
let resized = await blizt({...})

/* Old school callback */
const blitz = Blitz.create('callback')
blitz({...}, function(output) {
    // run your callback.
})

History

This is really after many rounds of research, reading and trying.

The resizer algorithm uses @ViliusL's Hermite script (Hermite resizer is really the fastest and gives reasonably good output). Extended with features you need.

Forks 1 worker to do the resizing so that it doesn't freeze your browser when resizing, unlike all other JS resizers out there.

You can easily do it with jquery toggle. By this toggle or slideToggle you will get nice animation and effect also.

$(function(){_x000D_
  $("#details_content").css("display","none");_x000D_
  $(".myButton").click(function(){_x000D_
    $("#details_content").slideToggle(1000);_x000D_
  })  _x000D_
})

<div class="main">_x000D_
    <h2 class="myButton" style="cursor:pointer">Click Me</h2>_x000D_

        <p>    of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>_x000D_

The problem appears to be that you are reinitializing the list to an empty list in each iteration:

while choice != 0:
    ...
    a = []
    a.append(s)

Try moving the initialization above the loop so that it is executed only once.

a = []
while choice != 0:
    ...
    a.append(s)

var temp="/yourapp/";
$(location).attr('href','http://abcd.com'+temp);

Try this... used as an alternative

From here - Remember:

<input v-model="something">

is essentially the same as:

<input
   v-bind:value="something"
   v-on:input="something = $event.target.value"
>

or (shorthand syntax):

<input
   :value="something"
   @input="something = $event.target.value"
>

So v-model is a two-way binding for form inputs. It combines v-bind, which brings a js value into the markup, and v-on:input to update the js value.

Use v-model when you can. Use v-bind/v-on when you must :-) I hope your answer was accepted.

v-model works with all the basic HTML input types (text, textarea, number, radio, checkbox, select). You can use v-model with input type=date if your model stores dates as ISO strings (yyyy-mm-dd). If you want to use date objects in your model (a good idea as soon as you're going to manipulate or format them), do this.

v-model has some extra smarts that it's good to be aware of. If you're using an IME ( lots of mobile keyboards, or Chinese/Japanese/Korean ), v-model will not update until a word is complete (a space is entered or the user leaves the field). v-input will fire much more frequently.

v-model also has modifiers .lazy, .trim, .number, covered in the doc.

If this is something you'll need to do often...then you may want to denormalize the relationship between tables A and B.

For example, on insert to table B, you could write zero or more entries to a juncion table mapping B to A based on partial mapping. Similarly, changes to either table could update this association.

This all depends on how frequently tables A and B are modified. If they are fairly static, then taking a hit on INSERT is less painful then repeated hits on SELECT.

CSS Clip-Path

Using a clip-path is a new, up and coming alternative. Its starting to get supported more and more and is now becoming well documented. Since it uses SVG to create the shape, it is responsive straight out of the box.

• Clip Path Generator

div {_x000D_
  width: 200px;_x000D_

CSS Transform

I have an alternative to web-tiki's transform answer.

As has been said, datetime has no format/string representational format.

You can change the string output with some formatting.

To convert your string to a datetime:

declare @date nvarchar(25) 
set @date = '2011-09-28 18:01:00' 

-- To datetime datatype
SELECT CONVERT(datetime, @date)

Gives:

-----------------------
2011-09-28 18:01:00.000

(1 row(s) affected)

To convert that to the string you want:

-- To VARCHAR of your desired format
SELECT CONVERT(VARCHAR(10), CONVERT(datetime, @date), 105) +' '+ CONVERT(VARCHAR(8), CONVERT(datetime, @date), 108)

Gives:

-------------------
28-09-2011 18:01:00

(1 row(s) affected)

Yes. You can use reflection. Something like this:

Type thisType = this.GetType();
MethodInfo theMethod = thisType.GetMethod(TheCommandString);
theMethod.Invoke(this, userParameters);

As described in Locale reference the best way to get language is:

Locale.getDefault().getLanguage()

this method returns string with language id according to ISO 639-1 standart

I changed the configuration of maven-compiler-plugin to add executable and fork with value true.

<configuration>
    <fork>true</fork>
    <source>1.6</source>
    <target>1.6</target>
    <executable>C:\Program Files\Java\jdk1.6.0_18\bin\javac</executable>
</configuration>

It worked for me.

Variables have scope, so yes it is appropriate to have variables that are specific to your function. You don't always have to be explicit about their definition; usually you can just use them. Only if you want to do something specific to the type of the variable, like append for a list, do you need to define them before you start using them. Typical example of this.

list = []
for i in stuff:
  list.append(i)

By the way, this is not really a good way to setup the list. It would be better to say:

list = [i for i in stuff] # list comprehension

...but I digress.

Your other question. The custom object should be a class itself.

class CustomObject(): # always capitalize the class name...this is not syntax, just style.
  pass
customObj = CustomObject()

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

You can use the following code inside the style tag:

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
/* IE10+ specific styles go here */  
}

Below is an example that worked for me:

<style type="text/css">

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
   /* IE10+ specific styles go here */  
   #flashvideo {
        width:320px;
        height:240;
        margin:-240px 0 0 350px;
        float:left;
    }

    #googleMap {
        width:320px;
        height:240;
        margin:-515px 0 0 350px;
        float:left;
        border-color:#000000;
    }
}

#nav li {
    list-style:none;
    width:240px;
    height:25px;
    }

#nav a {
    display:block;
    text-indent:-5000px;
    height:25px;
    width:240px;
    }
</style>

Please note that since (#nav li) and (#nav a) are outside of the @media screen ..., they are general styles.

Just call plt.show() at the end:

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0,50,60,80])
for i in np.arange(1,5):
    z = 68 + 4 * np.random.randn(50)
    zm = np.cumsum(z) / range(1,len(z)+1)
    plt.plot(zm)    

n = np.arange(1,51)
su = 68 + 4 / np.sqrt(n)
sl = 68 - 4 / np.sqrt(n)

plt.plot(n,su,n,sl)

plt.show()

WebRTC is designed for high-performance, high quality communication of video, audio and arbitrary data. In other words, for apps exactly like what you describe.

WebRTC apps need a service via which they can exchange network and media metadata, a process known as signaling. However, once signaling has taken place, video/audio/data is streamed directly between clients, avoiding the performance cost of streaming via an intermediary server.

WebSocket on the other hand is designed for bi-directional communication between client and server. It is possible to stream audio and video over WebSocket (see here for example), but the technology and APIs are not inherently designed for efficient, robust streaming in the way that WebRTC is.

As other replies have said, WebSocket can be used for signaling.

I maintain a list of WebRTC resources: strongly recommend you start by looking at the 2013 Google I/O presentation about WebRTC.

You may try this

finish();
startActivity(getIntent());

This question was asked before: How do I restart an Android Activity

.OrderByDescending(i=>i.id).First(1)

Regarding the performance concern, it is very likely that this method is theoretically slower than a linear approach. However, in reality, most of the time we are not dealing with the data set that is big enough to make any difference.

If performance is a main concern, Seattle Leonard's answer should give you linear time complexity. Alternatively, you may also consider to start with a different data structure that returns the max value item at constant time.

If you want to declare date and then use it in SQL Developer.

DEFINE PROPp_START_DT = TO_DATE('01-SEP-1999')

SELECT * 
FROM proposal 
WHERE prop_start_dt = &PROPp_START_DT

I encountered the same problem and I don't particularly like using aliases (as regular's suggested), and if you don't like them too then here's another workaround that I use, you first have to create a tiny executable bash script, say setenv.sh:

#!/bin/sh

# Add your local node_modules bin to the path
export PATH="$(npm bin):$PATH"

# execute the rest of the command
exec "$@"

and then you can then use any executables in your local /bin using this command:

./setenv.sh <command>
./setenv.sh 6to5-node server.js
./setenv.sh grunt

If you're using scripts in package.json then:

...,
scripts: {
    'start': './setenv.sh <command>'
}

You can do summary(santa$Believe) and you will get the count for TRUE and FALSE

>>> keys = ('name', 'age', 'food')
>>> values = ('Monty', 42, 'spam')
>>> dict(zip(keys, values))
{'food': 'spam', 'age': 42, 'name': 'Monty'}

There are different regex engines but I think most of them will work with this:

apple|banana

well,

I used System.setProperty("java.net.preferIPv4Stack" , "true"); and it works from JAVA, but it doesn't work on JBOSS AS7.

Here is my work around solution,

Add the below line to the end of the file ${JBOSS_HOME}/bin/standalone.conf.bat (just after :JAVA_OPTS_SET )

set "JAVA_OPTS=%JAVA_OPTS% -Djava.net.preferIPv4Stack=true"

Note: restart JBoss server

One nifty trick that I've recently found is to use PHP's create_function() to create an anonymous/lambda function for one-shot use. It's useful for PHP functions like array_map(), preg_replace_callback(), or usort() that use callbacks for custom processing. It looks pretty much like it does an eval() under the covers, but it's still a nice functional-style way to use PHP.

It is not possible to do this with just CSS alone, you will need to use Javascript.

<img src="default_image.jpg" id="image" width="100" height="100" alt="" />


<a href="page.html" onmouseover="document.images['image'].src='mouseover.jpg';" onmouseout="document.images['image'].src='default_image.jpg';"/>Text</a>

The source code for clear():

public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
}

The source code for removeAll()(As defined in AbstractCollection):

public boolean removeAll(Collection<?> c) {
    boolean modified = false;
    Iterator<?> e = iterator();
    while (e.hasNext()) {
        if (c.contains(e.next())) {
            e.remove();
            modified = true;
        }
    }
    return modified;
}

clear() is much faster since it doesn't have to deal with all those extra method calls.

And as Atrey points out, c.contains(..) increases the time complexity of removeAll to O(n²) as opposed to clear's O(n).

The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?

I ran into this error after my client PC crashed, the jest --watch command I was running on the server persisted, and I tried to run jest --watch again.

The addition to /etc/sysctl.conf described in the answers above worked around this issue, but it was also important to find my old process via ps aux | grep node and kill it.

Working answers are already given but I want to add a check that acts as a fail-safe in case the flask variable is not available. When you use:

var myVariable = {{ flaskvar | tojson }};

if there is an error that causes the variable to be non existent, resulting errors may produce unexpected results. To avoid this:

{% if flaskvar is defined and flaskvar %}
var myVariable = {{ flaskvar | tojson }};
{% endif %}

Try the negation operand - 'not'!

Well, if you can perform 'AND' operation on an if statement using nested 'if's (refer previous answers), then you can do the same thing with 'if not' to perform an 'or' operation.

If you haven't got the idea quite as yet, read on. Otherwise, just don't waste your time and get back to programming.

Just as nested 'if's are satisfied only when all conditions are true, nested 'if not's are satisfied only when all conditions are false. This is similar to what you want to do with an 'or' operand, isn't it?

Even when any one of the conditions in the nested 'if not' is true, the whole statement remains non-satisfied. Hence, you can use negated 'if's in succession by remembering that the body of the condition statement should be what you wanna do if all your nested conditions are false. The body that you actually wanted to give should come under the else statement.

And if you still didn't get the jist of the thing, sorry, I'm 16 and that's the best I can do to explain.

Its not possible as you are expecting. But you can do something like this. Pass the your java script value to the servlet/controller, do your processing and then pass this value to the jsp page by putting it into some object's as your requirement. Then you can use this value as you want.

You want a multiple attribute selector

$("input[type='checkbox'][name='ProductCode']").each(function(){ ...

or

$("input:checkbox[name='ProductCode']").each(function(){ ...

It would be better to use a CSS class to identify those that you want to select however as a lot of the modern browsers implement the document.getElementsByClassName method which will be used to select elements and be much faster than selecting by the name attribute

It's a lose of time to implement from scratch this functionality. I implemented the library recommended by SalutonMondo and I am very satisfied. It is very simple to use and very quick. I improved the original library and I added a new click listener for item click. Also I added font awesome library (http://fortawesome.github.io/Font-Awesome/) and now you can simply add a new item title and specify the icon name from font awesome.

Here is the github link

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

Old question but worth adding an answer if using .NET Core 3.0 or later. JSON serialization/deserialization is built into the framework (System.Text.Json), so you don't have to use third party libraries any more. Here's an example based off the top answer given by @Icarus

using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var json = "[{\"Name\":\"John Smith\", \"Age\":35}, {\"Name\":\"Pablo Perez\", \"Age\":34}]";

            // use the built in Json deserializer to convert the string to a list of Person objects
            var people = System.Text.Json.JsonSerializer.Deserialize<List<Person>>(json);

            foreach (var person in people)
            {
                Console.WriteLine(person.Name + " is " + person.Age + " years old.");
            }
        }

        public class Person
        {
            public int Age { get; set; }
            public string Name { get; set; }
        }
    }
}

In Swift 4.2: You can use

myArray.append("Tim") //To add "Tim" into array

or

myArray.insert("Tim", at: 0) //Change 0 with specific location 

I had this same problem and discovered (via this answer to a similar question) that the problem was that I didn't properly indent the docstring properly. Unfortunately IDLE doesn't give useful feedback here, but once I fixed the docstring indentation, the problem went away.

Specifically --- bad code that generates indentation errors:

def my_function(args):
"Here is my docstring"
    ....

Good code that avoids indentation errors:

def my_function(args):
    "Here is my docstring"
    ....

Note: I'm not saying this is the problem, but that it might be, because in my case, it was!

Thanks @twoleggedhorse.

Here is the solution.

1. First we created a function

   CREATE FUNCTION GetAIntFromStoredProc(@parm Nvarchar(50)) RETURNS INTEGER
   
   AS
   BEGIN
      DECLARE @id INTEGER
   
      set @id= (select TOP(1) id From tbl where col=@parm)
   
      RETURN @id
   END
   

2. then we do the select query

   Select col1, col2, col3,
   GetAIntFromStoredProc(T.col1) As col4
   From Tbl as T
   Where col2=@parm
   

There is no guarantee that a GUID contains alpha characters. FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF is a valid GUID so is 00000000-0000-0000-0000-000000000000 and anything in between.

If you are using .NET 4.0, you can use the answer above for the Guid.Parse and Guid.TryParse. Otherwise, you can do something like this:

public static bool TryParseGuid(string guidString, out Guid guid)
{
    if (guidString == null) throw new ArgumentNullException("guidString");
    try
    {
        guid = new Guid(guidString);
        return true;
    }
    catch (FormatException)
    {
        guid = default(Guid);
        return false;
    }
}

Alternative to docker ps --size

As "docker ps --size" produces heavy IO load on host, it is not feasable running such command every minute in a production environment. Therefore we have to do a workaround in order to get desired container size or to be more precise, the size of the RW-Layer with a low impact to systems perfomance.

This approach gathers the "device name" of every container and then checks size of it using "df" command. Those "device names" are thin provisioned volumes that a mounted to / on each container. One problem still persists as this observed size also implies all the readonly-layers of underlying image. In order to address this we can simple check size of used container image and substract it from size of a device/thin_volume.

One should note that every image layer is realized as a kind of a lvm snapshot when using device mapper. Unfortunately I wasn't able to get my rhel system to print out those snapshots/layers. Otherwise we could simply collect sizes of "latest" snapshots. Would be great if someone could make things clear. However...

After some tests, it seems that creation of a container always adds an overhead of approx. 40MiB (tested with containers based on Image "httpd:2.4.46-alpine"):

1. docker run -d --name apache httpd:2.4.46-alpine // now get device name from docker inspect and look it up using df
2. df -T -> 90MB whereas "Virtual Size" from "docker ps --size" states 50MB and a very small payload of 2Bytes -> mysterious overhead 40MB
3. curl/download of a 100MB file within container
4. df -T -> 190MB whereas "Virtual Size" from "docker ps --size" states 150MB and payload of 100MB -> overhead 40MB

Following shell prints results (in bytes) that match results from "docker ps --size" (but keep in mind mentioned overhead of 40MB)

for c in  $(docker ps -q); do \
container_name=$(docker inspect -f "{{.Name}}" ${c} | sed 's/^\///g' ); \
device_n=$(docker inspect -f "{{.GraphDriver.Data.DeviceName}}" ${c} | sed 's/.*-//g'); \
device_size_kib=$(df -T | grep ${device_n} | awk '{print $4}'); \
device_size_byte=$((1024 * ${device_size_kib})); \
image_sha=$(docker inspect -f "{{.Image}}" ${c} | sed 's/.*://g' ); \
image_size_byte=$(docker image inspect -f "{{.Size}}" ${image_sha}); \
container_size_byte=$((${device_size_byte} - ${image_size_byte})); \
\
echo my_node_dm_device_size_bytes\{cname=\"${container_name}\"\} ${device_size_byte}; \
echo my_node_dm_container_size_bytes\{cname=\"${container_name}\"\} ${container_size_byte}; \
echo my_node_dm_image_size_bytes\{cname=\"${container_name}\"\} ${image_size_byte}; \
done

You should be able to simply do this:

Context context = new InitialContext();
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

If you are looking it up from a remote destination you need to use the WL initial context factory like this:

Hashtable<String, String> h = new Hashtable<String, String>(7);
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, pURL); //For example "t3://127.0.0.1:7001"
h.put(Context.SECURITY_PRINCIPAL, pUsername);
h.put(Context.SECURITY_CREDENTIALS, pPassword);

InitialContext context = new InitialContext(h);
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

weblogic.jndi.WLInitialContextFactory

You can do it without using plugins.

In the latest version of vscode that I'm using (1.17.0) you can simply open the branch that you want (from the bottom left menu) then press ctrl+shift+p and type Git: Merge branch and then choose the other branch that you want to merge from (to the current one)

Have you checked in console if data from form is properly serialized? Is ajax request successful? Also you didn't close placeholder quote in, which can cause some problems:

 <textarea name="comentarii" cols="36" rows="5" placeholder="Message>  

Diego's comment on the answer given by SpinyMan is important because the empty() method will remove the select2 instance, so any custom options will no longer be retained. If you want to keep existing select2 options you must save them, destroy the existing select2 instance, and then re-initialize. You can do that like so:

const options = JSON.parse(JSON.stringify(
  $('#inputhidden').data('select2').options.options
));
options.data = data;

$('#inputhidden').empty().select2('destroy').select2(options);

I would recommend to always explicitly pass the select2 options however, because the above only copies over simple options and not any custom callbacks or adapters. Also note that this requires the latest stable release of select2 (4.0.13 at the time of this post).

I wrote generic functions to handle this with a few features:

• can handle selectors that return multiple instances
• use the existing select2's instance options (default) or pass in a new set of options
• keep any already-selected values (default) that are still valid, or clear them entirely

function select2UpdateOptions(
  selector,
  data,
  newOptions = null,
  keepExistingSelected = true
) {
  // loop through all instances of the matching selector and update each instance
  $(selector).each(function() {
    select2InstanceUpdateOptions($(this), data, newOptions, keepExistingSelected);
  });
}

// update an existing select2 instance with new data options
function select2InstanceUpdateOptions(
  instance,
  data,
  newOptions = null,
  keepSelected = true
) {
  // make sure this instance has select2 initialized
  // @link https://select2.org/programmatic-control/methods#checking-if-the-plugin-is-initialized
  if (!instance.hasClass('select2-hidden-accessible')) {
    return;
  }

  // get the currently selected options
  const existingSelected = instance.val();

  // by default use the existing options of the select2 instance unless overridden
  // this will not copy over any callbacks or custom adapters however
  const options = (newOptions)
    ? newOptions
    : JSON.parse(JSON.stringify(instance.data('select2').options.options))
  ;

  // set the new data options that will be used
  options.data = data;
      
  // empty the select and destroy the existing select2 instance
  // then re-initialize the select2 instance with the given options and data
  instance.empty().select2('destroy').select2(options);
      
  // by default keep options that were already selected;
  // any that are now invalid will automatically be cleared
  if (keepSelected) {
    instance.val(existingSelected).trigger('change');
  }
}

Two years on, and this issue is still around...

In iOS 8 / XCode 6.1, I was sometimes finding that my UILabel (created in a UITableViewCell, with AutoLayout turned on, and flexible constraints so it had plenty of space) wouldn't resize itself to fit the text string.

The solution, as in previous years, was to set the text, and then call sizeToFit.

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    . . .
    cell.lblCreatedAt.text = [note getCreatedDateAsString];
    [cell.lblCreatedAt sizeToFit];

(Sigh.)

atli's answer really helped me understand this. Here is an example of how to iterate through a two-dimensional array. This sample shows how to find values for known names of an array and also a foreach where you just go through all of the fields you find there. I hope it helps someone.

$array = array(
    0 => array(
        'name' => 'John Doe',
        'email' => '[email protected]'
    ),
    1 => array(
        'name' => 'Jane Doe',
        'email' => '[email protected]'
    ),
);

foreach ( $array  as $groupid => $fields) {
    echo "hi element ". $groupid . "\n";
    echo ". name is ". $fields['name'] . "\n";
    echo ". email is ". $fields['email'] . "\n";
    $i = 0;
    foreach ($fields as $field) {
         echo ". field $i is ".$field . "\n";
        $i++;
    }
}

Outputs:

hi element 0
. name is John Doe
. email is [email protected]
. field 0 is John Doe
. field 1 is [email protected]
hi element 1
. name is Jane Doe
. email is [email protected]
. field 0 is Jane Doe
. field 1 is [email protected]

You can use df.plot.scatter, and pass an array to c= argument defining the color of each point:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
colors = np.where(df["key1"]==4,'r','-')
colors[df["key1"]==6] = 'g'
colors[df["key1"]==8] = 'b'
print(colors)
df.plot.scatter(x="one",y="two",c=colors)
plt.show()

Podfile.lock file right under Podfile within your project.

The main thing is , Force it to open through your favourite TextEditor, like Sublime or TextEdit [Open With -> Select Sublime] as it doesn't give an option straight away to open.

Actually, it feels like swift is trying to promote strings to be treated less like objects and more like values. However this doesn't mean under the hood swift doesn't treat strings as objects, as am sure you all noticed that you can still invoke methods on strings and use their properties.

For example:-

//example of calling method (String to Int conversion)
let intValue = ("12".toInt())
println("This is a intValue now \(intValue)")


//example of using properties (fetching uppercase value of string)
let caUpperValue = "ca".uppercaseString
println("This is the uppercase of ca \(caUpperValue)")

In objectC you could pass the reference to a string object through a variable, on top of calling methods on it, which pretty much establishes the fact that strings are pure objects.

Here is the catch when you try to look at String as objects, in swift you cannot pass a string object by reference through a variable. Swift will always pass a brand new copy of the string. Hence, strings are more commonly known as value types in swift. In fact, two string literals will not be identical (===). They are treated as two different copies.

let curious = ("ca" === "ca")
println("This will be false.. and the answer is..\(curious)")

As you can see we are starting to break aways from the conventional way of thinking of strings as objects and treating them more like values. Hence .isEqualToString which was treated as an identity operator for string objects is no more a valid as you can never get two identical string objects in Swift. You can only compare its value, or in other words check for equality(==).

 let NotSoCuriousAnyMore = ("ca" == "ca")
 println("This will be true.. and the answer is..\(NotSoCuriousAnyMore)")

This gets more interesting when you look at the mutability of string objects in swift. But thats for another question, another day. Something you should probably look into, cause its really interesting. :) Hope that clears up some confusion. Cheers!

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.

This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.

select num_rows from all_tables where table_name = 'MY_TABLE'

This query counts the current number of rows in MY_TABLE

select count(*) from my_table

By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.

1. In the documentation there's an asterisk by the column name, which leads to this note:

   Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.

   This means that unless you have gathered statistics on the table then this column will not have any data.

2. Statistics gathered in 11g+ with the default estimate_percent, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.

If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.

Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.

If you want to retrieve the key's value if it exists, you can also use

try:
    value = a[key]
except KeyError:
    # Key is not present
    pass

If you want to retrieve a default value when the key does not exist, use value = a.get(key, default_value). If you want to set the default value at the same time in case the key does not exist, use value = a.setdefault(key, default_value).

Note: this is JQuery. See Sébastien answer for Javascript

$(function() {
    var temp="a"; 
    $("#MySelect").val(temp);
});

<select name="MySelect" id="MySelect">
    <option value="a">a</option>
    <option value="b">b</option>
    <option value="c">c</option>
</select>

I use iFrame to insert the content from another page and CSS mentioned above is NOT working as expected. I have to use the parameter scrolling="no" even if I use HTML 5 Doctype

I've had this problem before, you can go to "advanced" tab of "choose a data source" page and click on "suggested types" button, and set the "number of rows" as much as you want. after that, the type and text qualified are set to the true values.

i applied the above solution and can convert my data to SQL.

I'd start by the distinction that exists in Scala between def, val and var.

• def - defines an immutable label for the right side content which is lazily evaluated - evaluate by name.

• val - defines an immutable label for the right side content which is eagerly/immediately evaluated - evaluated by value.

• var - defines a mutable variable, initially set to the evaluated right side content.

Example, def

scala> def something = 2 + 3 * 4 
something: Int
scala> something  // now it's evaluated, lazily upon usage
res30: Int = 14

Example, val

scala> val somethingelse = 2 + 3 * 5 // it's evaluated, eagerly upon definition
somethingelse: Int = 17

Example, var

scala> var aVariable = 2 * 3
aVariable: Int = 6

scala> aVariable = 5
aVariable: Int = 5

According to above, labels from def and val cannot be reassigned, and in case of any attempt an error like the below one will be raised:

scala> something = 5 * 6
<console>:8: error: value something_= is not a member of object $iw
       something = 5 * 6
       ^

When the class is defined like:

scala> class Person(val name: String, var age: Int)
defined class Person

and then instantiated with:

scala> def personA = new Person("Tim", 25)
personA: Person

an immutable label is created for that specific instance of Person (i.e. 'personA'). Whenever the mutable field 'age' needs to be modified, such attempt fails:

scala> personA.age = 44
personA.age: Int = 25

as expected, 'age' is part of a non-mutable label. The correct way to work on this consists in using a mutable variable, like in the following example:

scala> var personB = new Person("Matt", 36)
personB: Person = Person@59cd11fe

scala> personB.age = 44
personB.age: Int = 44    // value re-assigned, as expected

as clear, from the mutable variable reference (i.e. 'personB') it is possible to modify the class mutable field 'age'.

I would still stress the fact that everything comes from the above stated difference, that has to be clear in mind of any Scala programmer.

In Swift 4.2 the notification names have moved to a different namespace. So now it's

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    addKeyboardListeners()
}


override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}


func addKeyboardListeners() {
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
}

@objc private extension WhateverTheClassNameIs {

    func keyboardWillShow(_ notification: Notification) {
        // Do something here.
    }

    func keyboardWillHide(_ notification: Notification) {
        // Do something here.
    }
}

If you'd want to generate multiple numbers using one seed you can do something like this:

public double[] GenerateNumbers(long seed, int amount) {
    double[] randomList = new double[amount];
    for (int i=0;i<amount;i++) {
        Random generator = new Random(seed);
        randomList[i] = Math.abs((double) (generator.nextLong() % 0.001) * 10000);
        seed--;
    }
    return randomList;
}

It will display the same list if you use the same seed.

Set the name in the form to check_list[] and you will be able to access all the checkboxes as an array($_POST['check_list'][]).

Here's a little sample as requested:

<form action="test.php" method="post">
    <input type="checkbox" name="check_list[]" value="value 1">
    <input type="checkbox" name="check_list[]" value="value 2">
    <input type="checkbox" name="check_list[]" value="value 3">
    <input type="checkbox" name="check_list[]" value="value 4">
    <input type="checkbox" name="check_list[]" value="value 5">
    <input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
            echo $check; //echoes the value set in the HTML form for each checked checkbox.
                         //so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
                         //in your case, it would echo whatever $row['Report ID'] is equivalent to.
    }
}
?>

You should use html():

SEE DEMO

$(document).ready(function(){
    $("#date").html('<span>'+$("#date").text().substring(0, 2) + '</span><br />'+$("#date").text().substring(3));     
});

for i,j in enumerate(words): # i---index of word----j
     #now you got index of your words (present in i)
     print(i) 

It is better to use the more powerful [[ as far as Bash is concerned.

Usual cases

if [[ $var ]]; then   # var is set and it is not empty
if [[ ! $var ]]; then # var is not set or it is set to an empty string

The above two constructs look clean and readable. They should suffice in most cases.

Note that we don't need to quote the variable expansions inside [[ as there is no danger of word splitting and globbing.

To prevent shellcheck's soft complaints about [[ $var ]] and [[ ! $var ]], we could use the -n option.

Rare cases

In the rare case of us having to make a distinction between "being set to an empty string" vs "not being set at all", we could use these:

if [[ ${var+x} ]]; then           # var is set but it could be empty
if [[ ! ${var+x} ]]; then         # var is not set
if [[ ${var+x} && ! $var ]]; then # var is set and is empty

We can also use the -v test:

if [[ -v var ]]; then             # var is set but it could be empty
if [[ ! -v var ]]; then           # var is not set
if [[ -v var && ! $var ]]; then   # var is set and is empty
if [[ -v var && -z $var ]]; then  # var is set and is empty

I just want to share the fact that my apk file was saved to my app "Data" directory and that I needed to change the permissions on the apk file to be world readable in order to allow it to be installed that way, otherwise the system was throwing "Parse error: There is a Problem Parsing the Package"; so using solution from @Horaceman that makes:

File file = new File(dir, "App.apk");
file.setReadable(true, false);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);

If you would use asp:dropdownlist you could select it easier by testSelect.Text.

Now you'd have to do a Request.Form["testSelect"] to get the value after pressed btnTes.

Hope it helps.

EDIT: You need to specify a name of the select (not only ID) to be able to Request.Form["testSelect"]

I was hoping for Math.average(values), but no such luck.

values = [0,4,8,2,5,0,2,6]
average = values.sum / values.size.to_f

instanceof can be used to determine the actual type of an object:

class A { }  
class C extends A { } 
class D extends A { } 

public static void testInstance(){
    A c = new C();
    A d = new D();
    Assert.assertTrue(c instanceof A && d instanceof A);
    Assert.assertTrue(c instanceof C && d instanceof D);
    Assert.assertFalse(c instanceof D);
    Assert.assertFalse(d instanceof C);
}

The problem is the length of the filenames. The first filename is only 7 chars long, so the tab occurs at char 8 (doing a tab after every 4 characters). However the next filenames are 8 chars long, so the next tab won't be until char 12. And if you had filenames longer than 11 chars, you'd run into the same problem again.

Your second question

How many columns can be used together as a primary key in a given table?

is implementation specific: it's defined in the actual DBMS being used.^[1],[2],[3] You have to inspect the technical specification of the database system you use. Some are very detailed, some are not. Searching the web about such limitations can be hard because the terminology varies. The term composite primary key should be mandatory ;)

If you cannot find explicit information, try creating a test database to ensure you can expect stable (and specific) handling of the limit violations (which are to be expected). Be careful to get the right information about this: sometimes the limits are accumulated, and you'll see different results with different database layouts.

• ^[1] sql - Composite primary key limit? - Stack Overflow
• ^[2] SQL Server - Max columns per primary key
• ^[3] How many maximum number of columns can be part of Primary Key in a table in Oracle 9i and 10g?

In SQL, I would have do it in one shot as

update table1 set col1 = new_value where col1 = old_value

but in Python Pandas, we could just do this:

data = [['ram', 10], ['sam', 15], ['tam', 15]] 
kids = pd.DataFrame(data, columns = ['Name', 'Age']) 
kids

which will generate the following output :

    Name    Age
0   ram     10
1   sam     15
2   tam     15

now we can run:

kids.loc[kids.Age == 15,'Age'] = 17
kids

which will show the following output

Name    Age
0   ram     10
1   sam     17
2   tam     17

which should be equivalent to the following SQL

update kids set age = 17 where age = 15

Use this for send email...

    .to("[email protected]")
    .cc("[email protected]")

    .start();

use build gradle :

To get mod_rewrite to work for me in Apache 2.4, I had to add the "Require all granted" line below.

<Directory /var/www>
   # Required if running apache > 2.4
   Require all granted

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

supposedly a similar requirement exists for Apache 2.2 as well, if you're using that:

<Directory /var/www>
   # Required if running apache 2.2
   Order allow,deny
   Allow from all

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

Note that an ErrorDocument 404 directive can sometimes override these things as well, so if it's not working try commenting out your ErrorDocument directive and see if it works. The above example can be used to ensure a site isn't served from cache by including a subfolder in the path, though the files reside at the root of the server.

You should create a new project in Code::Blocks, and make sure it's 'Console Application'.

Add your .cpp files into the project so they are all compiled and linked together.

Additionally to Eugene Retunsky's answer, quoting from $http documentation regarding the response:

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.

• status – {number} – HTTP status code of the response.

• headers – {function([headerName])} – Header getter function.

• config – {Object} – The configuration object that was used to generate the request.

• statusText – {string} – HTTP status text of the response.

Please note that the argument callback order for $resource (v1.6) is not the same as above:

Success callback is called with (value (Object|Array), responseHeaders (Function), status (number), statusText (string)) arguments, where the value is the populated resource instance or collection object. The error callback is called with (httpResponse) argument.

a PK will become a clustered index unless you specify non clustered

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

I had tried:

string[] sample = new string[0];

But I could only insert one string into it, and then I got an exceptionOutOfBound error, so I just simply put a size for it, like

string[] sample = new string[100];

Or another way that work for me:

List<string> sample = new List<string>();

Assigning Value for list:

sample.Add(your input);

In C++11, a constructor can call another constructor overload:

class Foo  {
     int d;         
public:
    Foo  (int i) : d(i) {}
    Foo  () : Foo(42) {} //New to C++11
};

Additionally, members can be initialized like this as well.

class Foo  {
     int d = 5;         
public:
    Foo  (int i) : d(i) {}
};

This should eliminate the need to create the initialization helper method. And it is still recommended not calling any virtual functions in the constructors or destructors to avoid using any members that might not be initialized.

It depends on the class you are using.

Dictionary<(Of <(TKey, TValue>)>) Class For Example Support This

The Dictionary<(Of <(TKey, TValue>)>) generic class provides a mapping from a set of keys to a set of values.

For purposes of enumeration, each item in the dictionary is treated as a KeyValuePair<(Of <(TKey, TValue>)>) structure representing a value and its key. The order in which the items are returned is undefined.

foreach (KeyValuePair kvp in myDictionary) {...}

Differences between an XML Schema Definition (XSD) and Document Type Definition (DTD) include:

• XML schemas are written in XML while DTD are derived from SGML syntax.
• XML schemas define datatypes for elements and attributes while DTD doesn't support datatypes.
• XML schemas allow support for namespaces while DTD does not.
• XML schemas define number and order of child elements, while DTD does not.
• XML schemas can be manipulated on your own with XML DOM but it is not possible in case of DTD.
• using XML schema user need not to learn a new language but working with DTD is difficult for a user.
• XML schema provides secure data communication i.e sender can describe the data in a way that receiver will understand, but in case of DTD data can be misunderstood by the receiver.
• XML schemas are extensible while DTD is not extensible.

Not all these bullet points are 100% accurate, but you get the gist.

On the other hand:

• DTD lets you define new ENTITY values for use in your XML file.
• DTD lets you extend it local to an individual XML file.

You can try this:

var fd = new FormData();
var data = [];           //<---------------declare array here
var file_data = object.get(0).files[i];
var other_data = $('form').serialize();

data.push(file_data);  //<----------------push the data here
data.push(other_data); //<----------------and this data too

fd.append("file", data);  //<---------then append this data

You want to use the live() function. See the docs.

For example:

$("#anchor1").live("click", function() {
    $("#anchor1").append('<a class="myclass" href="#">test4</a>');
});

I tried @knittl's write-tree/commit-tree approach.

branch-a: the kept branch

branch-b: the abandoned branch

// goto branch-a branch
$ git checkout branch-a

$ git write-tree
6fa6989240d2fc6490f8215682a20c63dac5560a // echo tree id? I guess

$ git commit-tree  -p branch-a -p branch-b 6fa6989240d2fc6490f8215682a20c63dac5560a
<type some commit message end with Ctrl-d>
20bc36a2b0f2537ed11328d1aedd9c3cff2e87e9 // echo new commit id

You'll have problems creating lists without commas. It shouldn't be too hard to transform your data so that it uses commas as separating character.

Once you have commas in there, it's a relatively simple list creation operations:

array1 = [1,2,3]
array2 = [4,5,6]

array3 = [array1, array2]

array4 = [7,8,9]
array5 = [10,11,12]

array3 = [array3, [array4, array5]]

When testing we get:

print(array3)

[[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]

And if we test with indexing it works correctly reading the matrix as made up of 2 rows and 2 columns:

array3[0][1]
[4, 5, 6]

array3[1][1]
[10, 11, 12]

Hope that helps.

Assuming alphanumeric words, you can use:

Search  = ^([A-Za-z0-9]+)$
Replace = able:"\1"

Or, if you just want to highlight the lines and use "Replace All" & "In Selection" (with the same replace):

Search = ^(.+)$

^ points to the start of the line.
$ points to the end of the line.

\1 will be the source match within the parentheses.

for more information on How to create Circle Android Custom Progress Bar view this link

Step 01 You should create an xml file on drawable file for configure the appearance of progress bar . So Im creating my xml file as circular_progress_bar.xml.

<?xml version="1.0" encoding="UTF-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="120"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="140">
<item android:id="@android:id/background">
<shape
    android:innerRadiusRatio="3"
    android:shape="ring"
    android:useLevel="false"
     android:angle="0"
     android:type="sweep"
    android:thicknessRatio="50.0">
    <solid android:color="#000000"/>
</shape>

 </item>
 <item android:id="@android:id/progress">
   <rotate
    android:fromDegrees="120"
    android:toDegrees="120">
<shape
    android:innerRadiusRatio="3"
    android:shape="ring"
     android:angle="0"
     android:type="sweep"
    android:thicknessRatio="50.0">
    <solid android:color="#ffffff"/>
</shape>
</rotate>
</item>
</layer-list>

Step 02 Then create progress bar on your xml file Then give the name of xml file on your drawable folder as the parth of android:progressDrawable

 <ProgressBar
            android:id="@+id/progressBar"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="150dp"
            android:layout_height="150dp"
            android:layout_marginLeft="0dp"
            android:layout_centerHorizontal="true"
            android:indeterminate="false"
            android:max="100"
            android:progressDrawable="@drawable/circular_progress_bar" />

Step 03 Visual the progress bar using thread

package com.example.progress;
import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.view.Menu;
import android.view.animation.Animation;
 import android.view.animation.TranslateAnimation;
 import android.widget.ProgressBar;
 import android.widget.TextView;

 public class MainActivity extends Activity {

  private ProgressBar progBar;
  private TextView text;
     private Handler mHandler = new Handler();
     private int mProgressStatus=0;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    progBar= (ProgressBar)findViewById(R.id.progressBar);
    text = (TextView)findViewById(R.id.textView1);

    dosomething();
}



  public void dosomething() {

  new Thread(new Runnable() {
        public void run() {
        final int presentage=0;
            while (mProgressStatus < 63) {
                mProgressStatus += 1;
                // Update the progress bar
                mHandler.post(new Runnable() {
                    public void run() {
                        progBar.setProgress(mProgressStatus);
                        text.setText(""+mProgressStatus+"%");

                    }
                });
                try {



                    Thread.sleep(50);

                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }).start();
  }


 }

public class Main {
 public static void main(String args[]) {
   String format = "|%1$-10s|%2$-10s|%3$-20s|\n";
   System.out.format(format, "A", "AA", "AAA");
   System.out.format(format, "B", "", "BBBBB");
   System.out.format(format, "C", "CCCCC", "CCCCCCCC");

   String ex[] = { "E", "EEEEEEEEEE", "E" };

   System.out.format(String.format(format, (Object[]) ex));
 }
}

differece in sizes of input doesnt effect the output

I have seen IFRAMEs applied very successfully as an easy way to make dynamic context menus, but the target audience of that web-app was only Internet Explorer users.

I would say that it all depends on your requirements. If you wish to make sure your page works equally well on every browser, avoid IFRAMEs. If you are targeting a narrow and well-known audience (eg. on the local Intranet) and you see a benefit in using IFRAMEs then I would say it's OK to do so.

I have same Issue, fixed by Adding @EnableMongoRepositories("in.topthree.util")

package in.topthree.core;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;

import in.topthree.util.Student;

@SpringBootApplication
@EnableMongoRepositories("in.topthree.util")
public class Run implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(Run.class, args);
        System.out.println("Run");
    }

    @Autowired
    private Process pr;

    @Override
    public void run(String... args) throws Exception {
        pr.saveDB(new Student("Testing", "FB"));
        System.exit(0);
    }

}

And my Repository is:

package in.topthree.util;

import org.springframework.data.mongodb.repository.MongoRepository;

public interface StudentMongo extends MongoRepository<Student, Integer> {

    public Student findByUrl(String url);
}

Now Its Working

you can also put labels inside plot:

plot(spline(sub$day, sub$counts), type ='l', labels = FALSE)

you'll get a warning. i think this is because labels is actually a parameter that's being passed down to a subroutine that plot runs (axes?). the warning will pop up because it wasn't directly a parameter of the plot function.

Another option like Gavin Palmer answer is to use the .pem file but with a curl option

1. download the last updated .pem file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)

2. set the option in your code instead of the php.ini file.

In your code

curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] .  "/../cacert-2017-09-20.pem");

NOTE: setting the cainfo in the php.ini like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini while testing your function.

Go to form's properties, ICON ... Choose an icon you want.

EDIT: try this

1. Edit App.Ico to make it look like you want.
2. In the property pane for your form, set the Icon property to your project's App.Ico file.
3. Rebuild solution.

And read this one icons

If you're using spring boot, just add an @Modifying annotation.

@Modifying
@Query
(value = "UPDATE user SET middleName = 'Mudd' WHERE id = 1", nativeQuery = true)
void updateMiddleName();

I have not seen any option in Microsoft SQL Server Management Studio 2012 to-date that will do that.

I am sure you can write something in T-SQL given the time.

Check out TOAD from QUEST - now owned by DELL.

http://www.toadworld.com/products/toad-for-oracle/f/10/t/9778.aspx

Select your rows.
Rt -click -> Export Dataset.
Choose Insert Statement format
Be sure to check “selected rows only”

Nice thing about toad, it works with both SQL server and Oracle. If you have to work with both, it is a good investment.

Based on Bluefeet's accepted response with an added nuance using OVER():

SELECT distributor_id,
    COUNT(*) total,
    SUM(case when level = 'exec' then 1 else 0 end) OVER() ExecCount,
    SUM(case when level = 'personal' then 1 else 0 end) OVER () PersonalCount
FROM yourtable
GROUP BY distributor_id

Using OVER() with nothing in the () will give you the total count for the whole dataset.

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

This is how it is done in jquery

$("#artifact_form").submit(function(){
    return ["jpg", "jpeg", "bmp", "gif", "png"].includes(/[^.]+$/.exec($("#artifact_file_name").val())[0])
  });

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

Adding to the correct answers above, the problem still might occur due to library nesting. In this case, try as the example below:

compile 'com.android.support:support-v4:20.+'
compile ('com.github.chrisbanes.actionbarpulltorefresh:extra-abs:+') { // example
    exclude group: 'com.android.support', module:'support-v4'
    exclude group: 'com.android.support', module:'appcompat-v7'
}

To invert a boolean Series, use ~s:

In [7]: s = pd.Series([True, True, False, True])

In [8]: ~s
Out[8]: 
0    False
1    False
2     True
3    False
dtype: bool

Using Python2.7, NumPy 1.8.0, Pandas 0.13.1:

In [119]: s = pd.Series([True, True, False, True]*10000)

In [10]:  %timeit np.invert(s)
10000 loops, best of 3: 91.8 µs per loop

In [11]: %timeit ~s
10000 loops, best of 3: 73.5 µs per loop

In [12]: %timeit (-s)
10000 loops, best of 3: 73.5 µs per loop

As of Pandas 0.13.0, Series are no longer subclasses of numpy.ndarray; they are now subclasses of pd.NDFrame. This might have something to do with why np.invert(s) is no longer as fast as ~s or -s.

Caveat: timeit results may vary depending on many factors including hardware, compiler, OS, Python, NumPy and Pandas versions.

If the two ranges to be tested (your given cell and your given range) are not in the same Worksheet, then Application.Intersect throws an error. Thus, a way to avoid it is with something like

Sub test_inters(rng1 As Range, rng2 As Range)
    If (rng1.Parent.Name = rng2.Parent.Name) Then
        Dim ints As Range
        Set ints = Application.Intersect(rng1, rng2)
        If (Not (ints Is Nothing)) Then
            ' Do your job
        End If
    End If
End Sub

In <body> you should have two <script> tags:

<script src="https://code.jquery.com/jquery-2.1.3.js"></script>
<script src="js/bootstrap.js"></script>

The first one will load jQuery from the CDN, and second one will load Bootstrap's Javascript from a local directory (in this case it's a directory called js).

<a href="#" onclick="SomeFunction()"  class="SomeClass">sth.</a>

this was my anchor tag. so return false on onClick="" event is not usefull here. I just removed href="#" property and it worked for me just like below

<a onclick="SomeFunction()"  class="SomeClass">sth.</a>

and i needed to add this css.

.SomeClass
{
    cursor: pointer;
}

to get IMEI (international mobile equipment identifier)

public String getIMEI(Activity activity) {
    TelephonyManager telephonyManager = (TelephonyManager) activity
            .getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager.getDeviceId();
}

to get device unique id

public String getDeviceUniqueID(Activity activity){
    String device_unique_id = Secure.getString(activity.getContentResolver(),
            Secure.ANDROID_ID);
    return device_unique_id;
}

Git doesn't think in terms of file versions. A version in git is a snapshot of the entire tree.

Given this, what you really want is a tree that has the latest content of most files, but with the contents of one file the same as it was 5 commits ago. This will take the form of a new commit on top of the old ones, and the latest version of the tree will have what you want.

I don't know if there's a one-liner that will revert a single file to the contents of 5 commits ago, but the lo-fi solution should work: checkout master~5, copy the file somewhere else, checkout master, copy the file back, then commit.

stat's "%s" format gives you the actual number of bytes in a file.

 find . -type f |
 xargs stat --format=%s |
 awk '{s+=$1} END {print s}'

Feel free to substitute your favourite method for summing numbers.

Try an simple loop:

var repeat = [], tmp, i = 0;

while(i < values.length){
  repeat.indexOf(tmp = values[i++].name) > -1 ? values.pop(i--) : repeat.push(tmp)
}

I prefer using the following solution for handling onClick events. This works for Activity and Fragments as well.

public class StartFragment extends Fragment implements OnClickListener{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.fragment_start, container, false);

        Button b = (Button) v.findViewById(R.id.StartButton);
        b.setOnClickListener(this);
        return v;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.StartButton:

            ...

            break;
        }
    }
}

You should use

inputvalue=Math.Round(inputValue, 2, MidpointRounding.AwayFromZero)

Math.Round

Math.Round rounds a double-precision floating-point value to a specified number of fractional digits.

MidpointRounding

Specifies how mathematical rounding methods should process a number that is midway between two numbers.

Basically the function above will take your inputvalue and round it to 2 (or whichever number you specify) decimal places. With MidpointRounding.AwayFromZero when a number is halfway between two others, it is rounded toward the nearest number that is away from zero. There is also another option you can use that rounds towards the nearest even number.

http://www.vancelucas.com/blog/fixing-ie7-z-index-issues-with-jquery/

$(function() {
var zIndexNumber = 1000;
$('div').each(function() {
    $(this).css('zIndex', zIndexNumber);
    zIndexNumber -= 10;
});
});

An auto-updated column is automatically updated to the current timestamp when the value of any other column in the row is changed from its current value. An auto-updated column remains unchanged if all other columns are set to their current values.

To explain it let's imagine you have only one row:

-------------------------------
| price | updated_at          |
-------------------------------
|  2    | 2018-02-26 16:16:17 |
-------------------------------

Now, if you run the following update column:

 update my_table
 set price = 2

it will not change the value of updated_at, since price value wasn't actually changed (it was already 2).

But if you have another row with price value other than 2, then the updated_at value of that row (with price <> 3) will be updated to CURRENT_TIMESTAMP.

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

Try this:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=\''+elemA+'\'&lon=\''+elemB+'\'&setLatLon=Set";

I found a bug in MySQL 5.1.72 when using the nested if() functions .... the value of column variables (e.g. qty_1) is blank inside the second if(), rendering it useless. Use the following construct instead:

case 
  when qty_1<='23' then price
  when '23'>qty_1 && qty_2<='23' then price_2
  when '23'>qty_2 && qty_3<='23' then price_3
  when '23'>qty_3 then price_4
  else 1
end

Perfectly fine.
You can't instantiate abstract classes.. but abstract classes can be used to house common implementations for m1() and m3().
So if m2() implementation is different for each implementation but m1 and m3 are not. You could create different concrete IAnything implementations with just the different m2 implementation and derive from AbstractThing -- honoring the DRY principle. Validating if the interface is completely implemented for an abstract class is futile..

Update: Interestingly, I find that C# enforces this as a compile error. You are forced to copy the method signatures and prefix them with 'abstract public' in the abstract base class in this scenario.. (something new everyday:)

It is Safari specific, at least at time of writing, being introduced in Safari 9.0. From the "What's new in Safari?" documentation for Safari 9.0:

Viewport Changes

Viewport meta tags using "width=device-width" cause the page to scale down to fit content that overflows the viewport bounds. You can override this behavior by adding "shrink-to-fit=no" to your meta tag as shown below. The added value will prevent the page from scaling to fit the viewport.

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">

In short, adding this to the viewport meta tag restores pre-Safari 9.0 behaviour.

Example

Here's a worked visual example which shows the difference upon loading the page in the two configurations.

The red section is the width of the viewport and the blue section is positioned outside the initial viewport (eg left: 100vw). Note how in the first example the page is zoomed to fit when shrink-to-fit=no is omitted (thus showing the out-of-viewport content) and the blue content remains off screen in the latter example.

The code for this example can be found at https://codepen.io/davidjb/pen/ENGqpv.

Without shrink-to-fit specified

With shrink-to-fit=no

Dispatching a block to the main queue is usually done from a background queue to signal that some background processing has finished e.g.

- (void)doCalculation
{
    //you can use any string instead "com.mycompany.myqueue"
    dispatch_queue_t backgroundQueue = dispatch_queue_create("com.mycompany.myqueue", 0);

    dispatch_async(backgroundQueue, ^{
        int result = <some really long calculation that takes seconds to complete>;

        dispatch_async(dispatch_get_main_queue(), ^{
            [self updateMyUIWithResult:result];
        });    
    });
}

In this case, we are doing a lengthy calculation on a background queue and need to update our UI when the calculation is complete. Updating UI normally has to be done from the main queue so we 'signal' back to the main queue using a second nested dispatch_async.

There are probably other examples where you might want to dispatch back to the main queue but it is generally done in this way i.e. nested from within a block dispatched to a background queue.

• background processing finished -> update UI
• chunk of data processed on background queue -> signal main queue to start next chunk
• incoming network data on background queue -> signal main queue that message has arrived
• etc etc

As to why you might want to dispatch to the main queue from the main queue... Well, you generally wouldn't although conceivably you might do it to schedule some work to do the next time around the run loop.

Alejandro nailed it, adding clarification to the exception (Ubuntu or Debian) - I don't have the rep to add to the answer itself:

I've tried all the possibilities. Nothing worked for me except the following. var element = document.querySelectorAll("input[id=btn1]"); element[0].setAttribute("disabled",true);

If you are working in some IDE like Eclipse or NetBeans, you should have that a.txt file in the root directory of your project. (and not in the folder where your .class files are built or anywhere else)

If not, you should specify the absolute path to that file.

Edit:
You would put the .txt file in the same place with the .class(usually also the .java file because you compile in the same folder) compiled files if you compile it by hand with javac. This is because it uses the relative path and the path tells the JVM the path where the executable file is located.

If you use some IDE, it will generate the compiled files for you using a Makefile or something similar for Windows and will consider it's default file structure, so he knows that the relative path begins from the root folder of the project.

This will listen to the changed event. I have tried the answers from others but those did not work for me and finally, this one worked.

Found other solution git reset HEAD~#numberOfCommits using which we can choose to select number of local commits you want to reset by keeping your changes intact. Hence, we get an opportunity to throw away all local commits as well as limited number of local commits.

Refer below screenshots showing git reset HEAD~1 in action:

As Diodeus stated, IE doesn't allow anything but the default border for <select> elements. However, I know of two hacks to achieve a similar effect :

1. Use a DIV that is placed absolutely at the same position as the dropdown and set it's borders. It will appear that the dropdown has a border.

2. Use a Javascript solution, for instance, the one provided here.

It may however prove to be too much effort, so you should evaluate if you really require the border.

Remove $CATALINA_HOME/webapps/ROOT. Update $CATALINA_HOME/conf/server.xml, make sure that Host element look like the following text:

<Host name="localhost"  appBase="webapps"
      unpackWARs="true" autoDeploy="false" deployOnStartup="false">
  <Context path="" docBase="myApp"></Context>

It works with Tomcat 8. autoDeploy and deployOnStartup need to set to false to prevent tomcat from deploying myApp twice.

Update for @angular/[email protected]: and over

In angular.json you can specify a port per "project"

"projects": {
    "my-cool-project": {
        ... rest of project config omitted
        "architect": {
            "serve": {
                "options": {
                    "port": 1337
                }
            }
        }
    }
}

All options available:

https://angular.io/guide/workspace-config#project-tool-configuration-options

Alternatively, you may specify the port each time when running ng serve like this:

ng serve --port 1337

With this approach you may wish to put this into a script in your package.json to make it easier to run each time / share the config with others on your team:

"scripts": {
    "start": "ng serve --port 1337"
}

Legacy:

Update for @angular/cli final:

Inside angular-cli.json you can specify the port in the defaults:

"defaults": {
  "serve": {
    "port": 1337
  }
}

Legacy-er:

Tested in [email protected]

The server in angular-cli comes from the ember-cli project. To configure the server, create an .ember-cli file in the project root. Add your JSON config in there:

{
   "port": 1337
}

Restart the server and it will serve on that port.

There are more options specified here: http://ember-cli.com/#runtime-configuration

{
  "skipGit" : true,
  "port" : 999,
  "host" : "0.1.0.1",
  "liveReload" : true,
  "environment" : "mock-development",
  "checkForUpdates" : false
}

Found a solution to Excel Mac2016 as having to paste the code into the relevant cell, enter, then go to the end of the formula within the header bar and enter the following:

Enter a formula as an array formula Image + SHIFT + RETURN or CONTROL + SHIFT + RETURN

The query below will result in dd-mmm-yy format.

select 
cast(DAY(getdate()) as varchar)+'-'+left(DATEname(m,getdate()),3)+'-'+  
Right(Year(getdate()),2)

The relevant Python documentation suggests the use of the EAFP coding style (Easier to Ask for Forgiveness than Permission). This means that the code

try:
    os.makedirs(path)
except OSError as exception:
    if exception.errno != errno.EEXIST:
        raise
    else:
        print "\nBE CAREFUL! Directory %s already exists." % path

is better than the alternative

if not os.path.exists(path):
    os.makedirs(path)
else:
    print "\nBE CAREFUL! Directory %s already exists." % path

The documentation suggests this exactly because of the race condition discussed in this question. In addition, as others mention here, there is a performance advantage in querying once instead of twice the OS. Finally, the argument placed forward, potentially, in favour of the second code in some cases --when the developer knows the environment the application is running-- can only be advocated in the special case that the program has set up a private environment for itself (and other instances of the same program).

Even in that case, this is a bad practice and can lead to long useless debugging. For example, the fact we set the permissions for a directory should not leave us with the impression permissions are set appropriately for our purposes. A parent directory could be mounted with other permissions. In general, a program should always work correctly and the programmer should not expect one specific environment.

There's a function empty() ready for you in std::string:

std::string a;
if(a.empty())
{
    //do stuff. You will enter this block if the string is declared like this
}

or

std::string a;
if(!a.empty())
{
    //You will not enter this block now
}
a = "42";
if(!a.empty())
{
    //And now you will enter this block.
}

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:

    <profile>
        <id>alternateBuildDir</id>
        <activation>
            <property>
                <name>alt.build.dir</name>
            </property>
        </activation>
        <build>
            <directory>${alt.build.dir}</directory>
        </build>
    </profile>

Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.

Here is short example of how serialization works. I was also learning about the same and I found two links useful. What Serialization is and how it can be done in .NET.

A sample program explaining serialization

If you don't understand the above program a much simple program with explanation is given here.

The redirect function cleans the output buffer and does a header('Location:...'); redirection and exits script execution. The part you are trying to echo will never be outputted.

You should either notify on the download page or notify on the page you redirect to about the missing data.

To do this in C you can use the sysctl(3) family of functions:

int count;
size_t count_len = sizeof(count);
sysctlbyname("hw.logicalcpu", &count, &count_len, NULL, 0);
fprintf(stderr,"you have %i cpu cores", count);

Interesting values to use in place of "hw.logicalcpu", which counts cores, are:

hw.physicalcpu - The number of physical processors available in the current power management mode.

hw.physicalcpu_max - The maximum number of physical processors that could be available this boot.

hw.logicalcpu - The number of logical processors available in the current power management mode.

hw.logicalcpu_max - The maximum number of logical processors that could be available this boot.

In this issue,If you have already installed & update pod in your system then your Xcode not being able to find the Pods library.To resolve this issue, please check for following causes that may take place:

1. You are using the workspace.
2. The Pods library builds.
3. The Pods library is referenced in the products group of your project.
4. Your target includes the Pods library in the link with frameworks build phase.

You didn't select post_id in the subquery. You have to select it in the subquery like this:

SELECT wp_woocommerce_order_items.order_id As No_Commande
FROM  wp_woocommerce_order_items
LEFT JOIN 
    (
        SELECT meta_value As Prenom, post_id  -- <----- this
        FROM wp_postmeta
        WHERE meta_key = '_shipping_first_name'
    ) AS a
ON wp_woocommerce_order_items.order_id = a.post_id
WHERE  wp_woocommerce_order_items.order_id =2198 

There are different ways of taking input in java like:

1) BufferedReader 2) Scanner 3) Command Line Arguments

BufferedReader Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.

Where Scanner is a simple text scanner which can parse primitive types and strings using regular expressions.

if you are writing a simple log reader Buffered reader is adequate. if you are writing an XML parser Scanner is the more natural choice.

For more information please refer:

Pandas 0.24.0+ solution

In Pandas 0.24.0 a new feature was introduced specifically designed for fast writes to Postgres. You can learn more about it here: https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html#io-sql-method

import csv
from io import StringIO

from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    # gets a DBAPI connection that can provide a cursor
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)

        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name

        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(
            table_name, columns)
        cur.copy_expert(sql=sql, file=s_buf)

engine = create_engine('postgresql://myusername:mypassword@myhost:5432/mydatabase')
df.to_sql('table_name', engine, method=psql_insert_copy)

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

You can do all that by using just one RelativeLayout (which, btw, don't need android:orientation parameter). So, instead of having a LinearLayout, containing a bunch of stuff, you can do something like:

<RelativeLayout>
    <ImageButton
        android:layout_width="wrap_content"
        android:id="@+id/the_first_one"
        android:layout_alignParentLeft="true"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_toRightOf="@+id/the_first_one"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"/>
</RelativeLayout>

As you noticed, there are some XML parameters missing. I was just showing the basic parameters you had to put. You can complete the rest.

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

If you want to even support for float values (Dot separated values) then you can use this expression :

var isNumber = /^\d+\.\d+$/.test(value);

Many of Microsoft's secure functions, including fopen_s(), are part of C11, so they should be portable now. You should realize that the secure functions differ in exception behaviors and sometimes in return values. Additionally you need to be aware that while these functions are standardized, it's an optional part of the standard (Annex K) that at least glibc (default on Linux) and FreeBSD's libc don't implement.

However, I fought this problem for a few years. I posted a larger set of conversion macros here., For your immediate problem, put the following code in an include file, and include it in your source code:

#pragma once
#if !defined(FCN_S_MACROS_H)
   #define   FCN_S_MACROS_H

   #include <cstdio>
   #include <string> // Need this for _stricmp
   using namespace std;

   // _MSC_VER = 1400 is MSVC 2005. _MSC_VER = 1600 (MSVC 2010) was the current
   // value when I wrote (some of) these macros.

   #if (defined(_MSC_VER) && (_MSC_VER >= 1400) )

      inline extern
      FILE*   fcnSMacro_fopen_s(char *fname, char *mode)
      {  FILE *fptr;
         fopen_s(&fptr, fname, mode);
         return fptr;
      }
      #define fopen(fname, mode)            fcnSMacro_fopen_s((fname), (mode))

   #else
      #define fopen_s(fp, fmt, mode)        *(fp)=fopen( (fmt), (mode))

   #endif //_MSC_VER

#endif // FCN_S_MACROS_H

Of course this approach does not implement the expected exception behavior.

The SQL statements that read data from a database query return the data in a result set. The SELECT statement is the standard way to select rows from a database and view them in a result set. The **java.sql.ResultSet** interface represents the result set of a database query.

• Get methods: used to view the data in the columns of the current row being pointed to by the cursor.

Using MetaData of a result set to fetch the exact column count

ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);

http://docs.oracle.com/javase/7/docs/api/java/sql/ResultSetMetaData.html

and further more to bind it to data model table

public static void main(String[] args) {
    Connection conn = null;
    Statement stmt = null;
    try {
        //STEP 2: Register JDBC driver
        Class.forName("com.mysql.jdbc.Driver");

        //STEP 3: Open a connection
        System.out.println("Connecting to a selected database...");
        conn = DriverManager.getConnection(DB_URL, USER, PASS);
        System.out.println("Connected database successfully...");

        //STEP 4: Execute a query
        System.out.println("Creating statement...");
        stmt = conn.createStatement();

        String sql = "SELECT id, first, last, age FROM Registration";
        ResultSet rs = stmt.executeQuery(sql);
        //STEP 5: Extract data from result set
        while(rs.next()){
            //Retrieve by column name
            int id  = rs.getInt("id");
            int age = rs.getInt("age");
            String first = rs.getString("first");
            String last = rs.getString("last");

            //Display values
            System.out.print("ID: " + id);
            System.out.print(", Age: " + age);
            System.out.print(", First: " + first);
            System.out.println(", Last: " + last);
        }
        rs.close();
    } catch(SQLException se) {
        //Handle errors for JDBC
        se.printStackTrace();
    } catch(Exception e) {
        //Handle errors for Class.forName
        e.printStackTrace();
    } finally {
        //finally block used to close resources
        try {
            if(stmt!=null)
                conn.close();
        } catch(SQLException se) {

very nice tutorial here : http://www.tutorialspoint.com/jdbc/

ResultSetMetaData meta = resultset.getMetaData();  // for a valid resultset object after executing query

Integer columncount = meta.getColumnCount();

int count = 1 ; // start counting from 1 always

String[] columnNames = null;

while(columncount <=count) {
    columnNames [i] = meta.getColumnName(i);
}

System.out.println (columnNames.size() ); //see the list and bind it to TableModel object. the to your jtbale.setModel(your_table_model);

I was facing the same issue earlier but I have somehow found the solution, You can try reg.predict([[3300]]).

The API used to allow scalar value but now you need to give a 2D array.

You can try this :

i=0
i=$((i+1))

you can convert it into date format by-

new_date<- as.Date(old_date, "%m/%d/%Y")} 

from new_date, you can get the month by strftime()

month<- strftime(new_date, "%m")

old_date<- "01/01/1979"
new_date<- as.Date(old_date, "%m/%d/%Y")
new_date
#[1] "1979-01-01"
month<- strftime(new_date,"%m")
month
#[1] "01"
year<- strftime(new_date, "%Y")
year
#[1] "1979"

I had a similar problem and I did something like the below mentioned steps with my Path environment variable to fix the problem

1. Located where my Anaconda3 was installed. I run Windows 7. Mine is located at C:\ProgramData\Anaconda3.

2. Open Control Panel - System - Advanced System Settings, under Advanced tab click on Environment Variables.

3. Under System Variables, located "Path" add the following: C:\ProgramData\Anaconda3\Scripts;C:\ProgramData\Anaconda3\;

Save and open new terminal. type in "conda". It worked for me.

Hope these steps help

The flags, or parameters that you can use with IFRAME and OBJECT embeds are documented here; the details about which parameter works with what player are also clearly mentioned:

YouTube Embedded Players and Player Parameters

You will notice that autoplay is supported by all players (AS3, AS2 and HTML5).

You want:

insert into prices (group, id, price)
select 
    7, articleId, 1.50
from article where name like 'ABC%';

where you just hardcode the constant fields.

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

Very late answer. If you don't care about the list order, you can use *arg expansion with set uniqueness to remove dupes, i.e.:

l = [*{*l}]

Why not use a media query range.

I'm currently working on a responsive layout for my employer and the ranges I'm using are as follows:

You have your main desktop styles in the body of the CSS file (1024px and above) and then for specific screen sizes I'm using:

@media all and (min-width:960px) and (max-width: 1024px) {
  /* put your css styles in here */
}

@media all and (min-width:801px) and (max-width: 959px) {
  /* put your css styles in here */
}

@media all and (min-width:769px) and (max-width: 800px) {
  /* put your css styles in here */
}

@media all and (min-width:569px) and (max-width: 768px) {
  /* put your css styles in here */
}

@media all and (min-width:481px) and (max-width: 568px) {
  /* put your css styles in here */
}

@media all and (min-width:321px) and (max-width: 480px) {
  /* put your css styles in here */
}

@media all and (min-width:0px) and (max-width: 320px) {
  /* put your css styles in here */
}

This will cover pretty much all devices being used - I would concentrate on getting the styling correct for the sizes at the end of the range (i.e. 320, 480, 568, 768, 800, 1024) as for all the others they will just be responsive to the size available.

Also, don't use px anywhere - use em's or %.

I have encountered this with Maven projects too. This is what I had to do to get around the problem:

First update your web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                    version="3.0">
<display-name>Servlet 3.0 Web Application</display-name>

Then right click on your project and select Properties -> Project Facets In there you will see the version of your Dynamic Web Module. This needs to change from version 2.3 or whatever to version 2.5 or above (I chose 3.0).

However to do this I had to uncheck the tick box for Dynamic Web Module -> Apply, then do a Maven Update on the project. Go back into the Project Facets window and it should already match your web.xml configuration - 3.0 in my case. You should be able to change it if not.

If this does not work for you then try right-clicking on the Dynamic Web Module Facet and select change version (and ensure it is not locked).

Or you can follow this steps:

1. Window > Show View > Other > General > navigator
2. There is a .settings folder under your project directory
3. Change the dynamic web module version in this line to 3.0
4. Change the Java version in this line to 1.5 or higher

don't forget to update your project

Hope that works!

Click is an event that fires immediately after you release the mouse button. So if you want to check in the handler for button2.Click if button1 was clicked before, all you could do is have a handler for button1.Click which sets a bool flag of your own making to true.

private bool button1WasClicked = false;

private void button1_Click(object sender, EventArgs e)
{
    button1WasClicked = true;
}

private void button2_Click(object sender, EventArgs e)
{
    if (textBox2.Text == textBox3.Text && button1WasClicked)
    { 
        StreamWriter myWriter = File.CreateText(@"c:\Program Files\text.txt");
        myWriter.WriteLine(textBox1.Text);
        myWriter.WriteLine(textBox2.Text);
        button1WasClicked = false;
    }
}

Regular Inheritance

With typical 3 level non-diamond non-virtual-inheritance inheritance, when you instantiate a new most-derived-object, new is called and the size required for the object on the heap is resolved from the class type by the compiler and passed to new.

new has a signature:

_GLIBCXX_WEAK_DEFINITION void *
operator new (std::size_t sz) _GLIBCXX_THROW (std::bad_alloc)

And makes a call to malloc, returning the void pointer

This address is then passed to the constructor of the most derived object, which will immediately call the middle constructor and then the middle constructor will immediately call the base constructor. The base then stores a pointer to its virtual table at the start of the object and then its attributes after it. This then returns to the middle constructor which will store its virtual table pointer at the same location and then its attributes after the attributes that would have been stored by the base constructor. It then returns to the most derived constructor, which stores a pointer to its virtual table at the same location and and then stores its attributes after the attributes that would have been stored by the middle constructor.

Because the virtual table pointer is overwritten, the virtual table pointer ends up always being the one of the most derived class. Virtualness propagates towards the most derived class so if a function is virtual in the middle class, it will be virtual in the most derived class but not the base class. If you polymorphically cast an instance of the most derived class to a pointer to the base class then the compiler will not resolve this to an indirect call to the virtual table and instead will call the function directly A::function(). If a function is virtual for the type you have cast it to then it will resolve to a call into the virtual table which will always be that of the most derived class. If it is not virtual for that type then it will just call Type::function() and pass the object pointer to it, cast to Type.

Actually when I say pointer to its virtual table, it's actually always an offset of 16 into the virtual table.

vtable for Base:
        .quad   0
        .quad   typeinfo for Base
        .quad   Base::CommonFunction()
        .quad   Base::VirtualFunction()

pointer is typically to the first function i.e. 

        mov     edx, OFFSET FLAT:vtable for Base+16

virtual is not required again in more-derived classes if it is virtual in a less-derived class because it propagates downwards in the direction of the most derived class. But it can be used to show that the function is indeed a virtual function, without having to check the classes it inherits's type definitions. When a function is declared virtual, from that point on, only the last implementation in the inheritance chain is used, but before that, it can still be used non-virtually if the object is cast to a type of a class before that in the inheritance chain that defines that method. It can be defined non-virtually in multiple classes before it in the chain before the virtualhood begins for a method of that name and signature, and they will use their own methods when referenced (and all classes after that definition in the chain will use that definition if they do not have their own definition, as opposed to virtual, which always uses the final definition). When a method is declared virtual, it must be implemented in that class or a more derived class in the inheritance chain for the full object that was constructed in order to be used.

override is another compiler guard that says that this function is overriding something and if it isn't then throw a compiler error.

= 0 means that this is an abstract function

final prevents a virtual function from being implemented again in a more derived class and will make sure that the virtual table of the most derived class contains the final function of that class.

= default makes it explicit in documentation that the compiler will use the default implementation

= delete give a compiler error if a call to this is attempted

If you call a non-virtual function, it will resolve to the correct method definition without going through the virtual table. If you call a virtual-function that has its final definition in an inherited class then it will use its virtual table and will pass the subobject to it automatically if you don't cast the object pointer to that type when calling the method. If you call a virtual function defined in the most derived class on a pointer of that type then it will use its virtual table, which will be the one at the start of the object. If you call it on a pointer of an inherited type and the function is also virtual in that class then it will use the vtable pointer of that subobject, which in the case of the first subobject will be the same pointer as the most derived class, which will not contain a thunk as the address of the object and the subobject are the same, and therefore it's just as simple as the method automatically recasting this pointer, but in the case of a 2nd sub object, its vtable will contain a non-virtual thunk to convert the pointer of the object of inherited type to the type the implementation in the most derived class expects, which is the full object, and therefore offsets the subobject pointer to point to the full object, and in the case of base subobject, will require a virtual thunk to offset the pointer to the base to the full object, such that it can be recast by the method hidden object parameter type.

Using the object with a reference operator and not through a pointer (dereference operator) breaks polymorphism and will treat virtual methods as regular methods. This is because polymorphic casting on non-pointer types can't occur due to slicing.

Virtual Inheritance

Consider

class Base
  {
      int a = 1;
      int b = 2;
  public:
      void virtual CommonFunction(){} ; //define empty method body
      void virtual VirtualFunction(){} ;
  };


class DerivedClass1: virtual public Base
  {
      int c = 3;
  public:
    void virtual DerivedCommonFunction(){} ;
     void virtual VirtualFunction(){} ;
  };
  
  class DerivedClass2 : virtual public Base
 {
     int d = 4;
 public:
     //void virtual DerivedCommonFunction(){} ;    
     void virtual VirtualFunction(){} ;
     void virtual DerivedCommonFunction2(){} ;
 };

class DerivedDerivedClass :  public DerivedClass1, public DerivedClass2
 {
   int e = 5;
 public:
     void virtual DerivedDerivedCommonFunction(){} ;
     void virtual VirtualFunction(){} ;
 };
 
 int main () {
   DerivedDerivedClass* d = new DerivedDerivedClass;
   d->VirtualFunction();
   d->DerivedCommonFunction();
   d->DerivedCommonFunction2();
   d->DerivedDerivedCommonFunction();
   ((DerivedClass2*)d)->DerivedCommonFunction2();
   ((Base*)d)->VirtualFunction();
 }

Without virtually inheriting the bass class you will get an object that looks like this:

Instead of this:

I.e. there will be 2 base objects.

In the virtual diamond inheritance situation above, after new is called, it passes the address of the allocated space for the object to the most derived constructor DerivedDerivedClass::DerivedDerivedClass(), which calls Base::Base() first, which writes its vtable in the base's dedicated subobject, it then DerivedDerivedClass::DerivedDerivedClass() calls DerivedClass1::DerivedClass1(), which writes its virtual table pointer to its subobject as well as overwriting the base subobject's pointer at the end of the object by consulting the passed VTT, and then calls DerivedClass1::DerivedClass1() to do the same, and finally DerivedDerivedClass::DerivedDerivedClass() overwrites all 3 pointers with its virtual table pointer for that inherited class. This is instead of (as illustrated in the 1st image above) DerivedDerivedClass::DerivedDerivedClass() calling DerivedClass1::DerivedClass1() and that calling Base::Base() (which overwrites the virtual pointer), returning, offsetting the address to the next subobject, calling DerivedClass2::DerivedClass2() and then that also calling Base::Base(), overwriting that virtual pointer, returning and then DerivedDerivedClass constructor overwriting both virtual pointers with its virtual table pointer (in this instance, the virtual table of the most derived constructor contains 2 subtables instead of 3).

The following is all compiled in debug mode -O0 so there will be redundant assembly

main:
.LFB8:
        push    rbp
        mov     rbp, rsp
        push    rbx
        sub     rsp, 24
        mov     edi, 48 //pass size to new
        call    operator new(unsigned long) //call new
        mov     rbx, rax  //move the address of the allocation to rbx
        mov     rdi, rbx  //move it to rdi i.e. pass to the call
        call    DerivedDerivedClass::DerivedDerivedClass() [complete object constructor] //construct on this address
        mov     QWORD PTR [rbp-24], rbx  //store the address of the object on the stack as the d pointer variable on -O0, will be optimised off on -Ofast if the address of the pointer itself isn't taken in the code, because this address does not need to be on the stack, it can just be passed in a register to the subsequent methods

Parenthetically, if the code were DerivedDerivedClass d = DerivedDerivedClass(), the main function would look like this:

main:
        push    rbp
        mov     rbp, rsp
        sub     rsp, 48 // make room for and zero 48 bytes on the stack for the 48 byte object, no extra padding required as the frame is 64 bytes with `rbp` and return address of the function it calls (no stack params are passed to any function it calls), hence rsp will be aligned by 16 assuming it was aligned at the start of this frame
        mov     QWORD PTR [rbp-48], 0
        mov     QWORD PTR [rbp-40], 0
        mov     QWORD PTR [rbp-32], 0
        mov     QWORD PTR [rbp-24], 0
        mov     QWORD PTR [rbp-16], 0
        mov     QWORD PTR [rbp-8], 0
        lea     rax, [rbp-48] // load the address of the cleared 48 bytes
        mov     rdi, rax // pass the address as a pointer to the 48 bytes cleared as the first parameter to the constructor
        call    DerivedDerivedClass::DerivedDerivedClass() [complete object constructor]
        //address is not stored on the stack because the object is used directly -- there is no pointer variable -- d refers to the object on the stack as opposed to being a pointer

Moving back to the original example, the DerivedDerivedClass constructor:

DerivedDerivedClass::DerivedDerivedClass() [complete object constructor]:
.LFB20:
        push    rbp
        mov     rbp, rsp
        sub     rsp, 16
        mov     QWORD PTR [rbp-8], rdi
.LBB5:
        mov     rax, QWORD PTR [rbp-8] // object address now in rax 
        add     rax, 32 //increment address by 32
        mov     rdi, rax // move object address+32 to rdi i.e. pass to call
        call    Base::Base() [base object constructor]
        mov     rax, QWORD PTR [rbp-8] //move object address to rax
        mov     edx, OFFSET FLAT:VTT for DerivedDerivedClass+8 //move address of VTT+8 to edx
        mov     rsi, rdx //pass VTT+8 address as 2nd parameter 
        mov     rdi, rax //object address as first (DerivedClass1 subobject)
        call    DerivedClass1::DerivedClass1() [base object constructor]
        mov     rax, QWORD PTR [rbp-8] //move object address to rax
        add     rax, 16  //increment object address by 16
        mov     edx, OFFSET FLAT:VTT for DerivedDerivedClass+24  //store address of VTT+24 in edx
        mov     rsi, rdx //pass address of VTT+24 as second parameter
        mov     rdi, rax //address of DerivedClass2 subobject as first
        call    DerivedClass2::DerivedClass2() [base object constructor]
        mov     edx, OFFSET FLAT:vtable for DerivedDerivedClass+24 //move this to edx
        mov     rax, QWORD PTR [rbp-8] // object address now in rax
        mov     QWORD PTR [rax], rdx. //store address of vtable for DerivedDerivedClass+24 at the start of the object
        mov     rax, QWORD PTR [rbp-8] // object address now in rax
        add     rax, 32  // increment object address by 32
        mov     edx, OFFSET FLAT:vtable for DerivedDerivedClass+120 //move this to edx
        mov     QWORD PTR [rax], rdx  //store vtable for DerivedDerivedClass+120 at object+32 (Base) 
        mov     edx, OFFSET FLAT:vtable for DerivedDerivedClass+72 //store this in edx
        mov     rax, QWORD PTR [rbp-8] //move object address to rax
        mov     QWORD PTR [rax+16], rdx //store vtable for DerivedDerivedClass+72 at object+16 (DerivedClass2)
        mov     rax, QWORD PTR [rbp-8]
        mov     DWORD PTR [rax+28], 5 // stores e = 5 in the object
.LBE5:
        nop
        leave
        ret

The DerivedDerivedClass constructor calls Base::Base() with a pointer to the object offset 32. Base stores a pointer to its virtual table at the address it receives and its members after it.

Base::Base() [base object constructor]:
.LFB11:
        push    rbp
        mov     rbp, rsp
        mov     QWORD PTR [rbp-8], rdi //stores address of object on stack (-O0)
.LBB2:
        mov     edx, OFFSET FLAT:vtable for Base+16  //puts vtable for Base+16 in edx
        mov     rax, QWORD PTR [rbp-8] //copies address of object from stack to rax
        mov     QWORD PTR [rax], rdx  //stores it address of object
        mov     rax, QWORD PTR [rbp-8] //copies address of object on stack to rax again
        mov     DWORD PTR [rax+8], 1 //stores a = 1 in the object
        mov     rax, QWORD PTR [rbp-8] //junk from -O0
        mov     DWORD PTR [rax+12], 2  //stores b = 2 in the object
.LBE2:
        nop
        pop     rbp
        ret

DerivedDerivedClass::DerivedDerivedClass() then calls DerivedClass1::DerivedClass1() with a pointer to the object offset 0 and also passes the address of VTT for DerivedDerivedClass+8

DerivedClass1::DerivedClass1() [base object constructor]:
.LFB14:
        push    rbp
        mov     rbp, rsp
        mov     QWORD PTR [rbp-8], rdi //address of object
        mov     QWORD PTR [rbp-16], rsi  //address of VTT+8
.LBB3:
        mov     rax, QWORD PTR [rbp-16]  //address of VTT+8 now in rax
        mov     rdx, QWORD PTR [rax]     //address of DerivedClass1-in-DerivedDerivedClass+24 now in rdx
        mov     rax, QWORD PTR [rbp-8]   //address of object now in rax
        mov     QWORD PTR [rax], rdx     //store address of DerivedClass1-in-.. in the object
        mov     rax, QWORD PTR [rbp-8]  // address of object now in rax
        mov     rax, QWORD PTR [rax]    //address of DerivedClass1-in.. now implicitly in rax
        sub     rax, 24                 //address of DerivedClass1-in-DerivedDerivedClass+0 now in rax
        mov     rax, QWORD PTR [rax]    //value of 32 now in rax
        mov     rdx, rax                // now in rdx
        mov     rax, QWORD PTR [rbp-8]  //address of object now in rax
        add     rdx, rax                //address of object+32 now in rdx
        mov     rax, QWORD PTR [rbp-16]  //address of VTT+8 now in rax
        mov     rax, QWORD PTR [rax+8]   //derference VTT+8+8; address of DerivedClass1-in-DerivedDerivedClass+72 (Base::CommonFunction()) now in rax
        mov     QWORD PTR [rdx], rax     //store at address object+32 (offset to Base)
        mov     rax, QWORD PTR [rbp-8]  //store address of object in rax, return
        mov     DWORD PTR [rax+8], 3    //store its attribute c = 3 in the object

        nop
        pop     rbp

Each inherited class has its own construction virtual table and the most derived class, DerivedDerivedClass, has a virtual table with a subtable for each, and it uses the pointer to the subtable to overwrite construction vtable pointer that the inherited class's constructor stored for each subobject. Each virtual method that needs a thunk (virtual thunk offsets the object pointer from the base to the start of the object and a non-virtual thunk offsets the object pointer from an inherited class's object that isn't the base object to the start of the whole object of the type DerivedDerivedClass). The DerivedDerivedClass constructor also uses a virtual table table (VTT) as a serial list of all the virtual table pointers that it needs to use and passes it to each constructor (along with the subobject address that the constructor is for), which they use to overwrite their and the base's vtable pointer.

DerivedDerivedClass::DerivedDerivedClass() then passes the address of the object+16 and the address of VTT for DerivedDerivedClass+24 to DerivedClass2::DerivedClass2() whose assembly is identical to DerivedClass1::DerivedClass1() except for the line mov DWORD PTR [rax+8], 3 which obviously has a 4 instead of 3 for d = 4.

After this, it replaces all 3 virtual table pointers in the object with pointers to offsets in DerivedDerivedClass's vtable to the representation for that class.

It depends on how Oracle was installed. During the installation process, the NLS_CHARACTERSET option is set. You may be able to find it with the query SELECT value$ FROM sys.props$ WHERE name = 'NLS_CHARACTERSET'.

If your NLS_CHARACTERSET is a Unicode encoding like UTF8, great. Using VARCHAR and NVARCHAR are pretty much identical. Stop reading now, just go for it. Otherwise, or if you have no control over the Oracle character set, read on.

VARCHAR — Data is stored in the NLS_CHARACTERSET encoding. If there are other database instances on the same server, you may be restricted by them; and vice versa, since you have to share the setting. Such a field can store any data that can be encoded using that character set, and nothing else. So for example if the character set is MS-1252, you can only store characters like English letters, a handful of accented letters, and a few others (like € and —). Your application would be useful only to a few locales, unable to operate anywhere else in the world. For this reason, it is considered A Bad Idea.

NVARCHAR — Data is stored in a Unicode encoding. Every language is supported. A Good Idea.

What about storage space? VARCHAR is generally efficient, since the character set / encoding was custom-designed for a specific locale. NVARCHAR fields store either in UTF-8 or UTF-16 encoding, base on the NLS setting ironically enough. UTF-8 is very efficient for "Western" languages, while still supporting Asian languages. UTF-16 is very efficient for Asian languages, while still supporting "Western" languages. If concerned about storage space, pick an NLS setting to cause Oracle to use UTF-8 or UTF-16 as appropriate.

What about processing speed? Most new coding platforms use Unicode natively (Java, .NET, even C++ std::wstring from years ago!) so if the database field is VARCHAR it forces Oracle to convert between character sets on every read or write, not so good. Using NVARCHAR avoids the conversion.

Bottom line: Use NVARCHAR! It avoids limitations and dependencies, is fine for storage space, and usually best for performance too.

If you need to add two strings you have to use the '+' operator

hence

msg['Subject'] = 'your string' + sys.argv[1]

and also you have to import sys in the beginning

as

import sys

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]
