Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

You can call qApp.exit();. I always use that and never had a problem with it.

If you application is a command line application, you might indeed want to return an exit code. It's completely up to you what the code is.

One way is to do:

sys.exit(0)

You will have to import sys of course.

Another way is to break out of your infinite loop. For example, you could do this:

while True:
    choice = get_input()
    if choice == "a":
        # do something
    elif choice == "q":
        break

Yet another way is to put your main loop in a function, and use return:

def run():
    while True:
        choice = get_input()
        if choice == "a":
            # do something
        elif choice == "q":
            return

if __name__ == "__main__":
    run()

The only reason you need the run() function when using return is that (unlike some other languages) you can't directly return from the main part of your Python code (the part that's not inside a function).

Just create a new array in your dictionary

Dictionary<string, List<string>> myDic = new Dictionary<string, List<string>>();
myDic.Add(newKey, new List<string>(existingList));

What I usually do is the following: a Gradle Clean, Rebuild and Sync all my Gradle files. After that I restart Android Studio, and I go to:

Select Theme -> Project Themes -> AppTheme

No need to initialize an empty DataFrame (you weren't even doing that, you'd need pd.DataFrame() with the parens).

Instead, to create a DataFrame where each series is a column,

1. make a list of Series, series, and
2. concatenate them horizontally with df = pd.concat(series, axis=1)

Something like:

series = [pd.Series(mat[name][:, 1]) for name in Variables]
df = pd.concat(series, axis=1)

Old question, but heavily referenced ... I think most people use other methods, but there is infact a to_hash method, it has to be setup right. Generally, pluck is a better answer after rails 4 ... answering this mainly because I had to search a bunch to find this thread or anything useful & assuming others are hitting the same problem...

Note: not recommending this for everyone, but edge cases!

From the ruby on rails api ... http://api.rubyonrails.org/classes/ActiveRecord/Result.html ...

This class encapsulates a result returned from calling #exec_query on any database connection adapter. For example:

result = ActiveRecord::Base.connection.exec_query('SELECT id, title, body FROM posts')
result # => #<ActiveRecord::Result:0xdeadbeef>

...

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ] ...

Try to use this , it works perfectly for me

  // 

   varb = new List<object>();

 // Example 

   varb.Add(new[] { float.Parse(GridView1.Rows[1].Cells[2].Text )});

 // JSON  + Serializ

public string Json()
        {  
            return (new JavaScriptSerializer()).Serialize(varb);
        }


//  Jquery SIDE 

  var datasets = {
            "Products": {
                label: "Products",
                data: <%= getJson() %> 
            }

Use option bty = "n" in legend to remove the box around the legend. For example:

legend(1, 5,
       "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
       bty = "n")

Another simple way to do it is with concat()

SELECT DISTINCT(CONCAT(a,b)) AS cc FROM my_table GROUP BY (cc);

Updated to rc.4: When trying to get data passed between sibling components in angular 2, The simplest way right now (angular.rc.4) is to take advantage of angular2's hierarchal dependency injection and create a shared service.

Here would be the service:

import {Injectable} from '@angular/core';

@Injectable()
export class SharedService {
    dataArray: string[] = [];

    insertData(data: string){
        this.dataArray.unshift(data);
    }
}

Now, here would be the PARENT component

import {Component} from '@angular/core';
import {SharedService} from './shared.service';
import {ChildComponent} from './child.component';
import {ChildSiblingComponent} from './child-sibling.component';
@Component({
    selector: 'parent-component',
    template: `
        <h1>Parent</h1>
        <div>
            <child-component></child-component>
            <child-sibling-component></child-sibling-component>
        </div>
    `,
    providers: [SharedService],
    directives: [ChildComponent, ChildSiblingComponent]
})
export class parentComponent{

} 

and its two children

child 1

import {Component, OnInit} from '@angular/core';
import {SharedService} from './shared.service'

@Component({
    selector: 'child-component',
    template: `
        <h1>I am a child</h1>
        <div>
            <ul *ngFor="#data in data">
                <li>{{data}}</li>
            </ul>
        </div>
    `
})
export class ChildComponent implements OnInit{
    data: string[] = [];
    constructor(
        private _sharedService: SharedService) { }
    ngOnInit():any {
        this.data = this._sharedService.dataArray;
    }
}

child 2 (It's sibling)

import {Component} from 'angular2/core';
import {SharedService} from './shared.service'

@Component({
    selector: 'child-sibling-component',
    template: `
        <h1>I am a child</h1>
        <input type="text" [(ngModel)]="data"/>
        <button (click)="addData()"></button>
    `
})
export class ChildSiblingComponent{
    data: string = 'Testing data';
    constructor(
        private _sharedService: SharedService){}
    addData(){
        this._sharedService.insertData(this.data);
        this.data = '';
    }
}

NOW: Things to take note of when using this method.

1. Only include the service provider for the shared service in the PARENT component and NOT the children.
2. You still have to include constructors and import the service in the children
3. This answer was originally answered for an early angular 2 beta version. All that has changed though are the import statements, so that is all you need to update if you used the original version by chance.

Just to clarify this: if we have a RadioGroup with several RadioButtons and need to activate one by index, implies that:

radioGroup.check(R.id.radioButtonId)

and

radioGroup.getChildAt(index)`

We can to do:

radioGroup.check(radioGroup.getChildAt(index).getId());

1. Go to http://px64.net/
2. mess around with opacity, add your image or choose color.
3. copy either html or css(css is easier) the site spits out.

4. Select your element aka the navbar.

5. .navbar{ background-image:url(link that the site provides); background-repeat:repeat;

6. Enjoy.

In order to delete a cookie set the expires date to something in the past. A function that does this would be.

var delete_cookie = function(name) {
    document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:01 GMT;';
};

Then to delete a cookie named roundcube_sessauth just do.

delete_cookie('roundcube_sessauth');

If you just want to print the substrings ...

char s[] = "THESTRINGHASNOSPACES";
size_t i, slen = strlen(s);
for (i = 0; i < slen; i += 4) {
  printf("%.4s\n", s + i);
}

AS per my study in css place always inside .like:-

 <head>
  <link href="css/grid.css" rel="stylesheet" />
 </head>

and for script its depen :-

1. If inside the script document. write present then it will be in the head tag.
2. If script contain DEFER attribute, BECAUSE defer downloaded all in parallel

You can also open your projects property pages in VS, and in "Build" section choose as "Target Framework" - .NET Framework 4. It helped me with the same issue.

By changing runProguard to minifyEnabled, part of the issue gets fixed.

But the fix can cause "Library Projects cannot set application Id" (you can find the fix for this here Android Studio 1.0 and error "Library projects cannot set applicationId").

By removing application Id in the build.gradle file, you should be good to go.

DESCRIBE DATABASE NAME; you need to specify the name of the database and the results will include the data type of each attribute.

what happened to me is that I have multiple projects in my solution. I meant to debug project 1, however, the project 2 was set as the default starting project. I fixed this by, right click on the project and select "Set as startup project", then running debugging is fine.

xml-writer(npm package) I think this is the good way to create and write xml file easy. Also it can be used on server side with nodejs.

var XMLWriter = require('xml-writer');
xw = new XMLWriter;
xw.startDocument();
xw.startElement('root');
xw.writeAttribute('foo', 'value');
xw.text('Some content');
xw.endDocument();
console.log(xw.toString());

Just to expand on @splattne's answer a little:

MapPath(string virtualPath) calls the following:

public string MapPath(string virtualPath)
{
    return this.MapPath(VirtualPath.CreateAllowNull(virtualPath));
}

MapPath(VirtualPath virtualPath) in turn calls MapPath(VirtualPath virtualPath, VirtualPath baseVirtualDir, bool allowCrossAppMapping) which contains the following:

//...
if (virtualPath == null)
{
    virtualPath = VirtualPath.Create(".");
}
//...

So if you call MapPath(null) or MapPath(""), you are effectively calling MapPath(".")

<div class="text-align" style="text-align: center;  ">
    <img class="img-responsive" style="margin: auto;" alt="" src="images/x.png ?>">
</div>

you can try this.

In my case I was using version 17.0.1 .It was showing error.

implementation "com.google.android.gms:play-services-location:17.0.1"

After changing version to 17.0.0, it worked

implementation "com.google.android.gms:play-services-location:17.0.0"

Reason might be I was using maps dependency of version 17.0.0 & location version as 17.0.1.It might have thrown error.So,try to maintain consistency in version numbers.

best and simple way to format the number is to use java-script function

var numberToformat = 1000000000
//add locality here, eg: if you need English currency add 'en' and if you need Danish currency format then use 'da-DA'.
var locality = 'en-EN';
numberToformat = numberToformat.toLocaleString(locality , { 
minimumFractionDigits: 4 })
document.write(numberToformat);

for more information click documentation page

Here is what worked for me (sugested by soulBit):

1) Restart using restart from the file menu
2) Once it started again, manually close and open it.

This is the simplest solution ever and it completely removes the annoying thing.

all of above answers would help you but you have to add three ports in the firewall of PC on which SQL Server is installed.

1. Add new TCP Local port in Windows firewall at port no. 1434

2. Add new program for SQL Server and select sql server.exe Path: C:\ProgramFiles\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\sqlservr.exe

3. Add new program for SQL Browser and select sqlbrowser.exe Path: C:\ProgramFiles\Microsoft SQL Server\90\Shared\sqlbrowser.exe

If You want to open dialogue window in browser to save, not open with PDF browser viewer (I was looking for this solution for a while), You should use 'D':

$pdf->Output('name.pdf', 'D');

Atom is still in beta (v0.123 as I'm writing this) but it's moving fast. Way faster than Sublime. New builds are released on a weekly basis, sometimes even few of them in the same week. In its short life span, it had more releases than Sublime which takes months to release a new feature or a bug fix. Here's an updated take on things looking back on the path Atom has taken since the launch of the beta:

1. Sublime has better performance than Atom. Simply because it's written in C++. Atom on the other hand is a web based desktop app built on top of Chromium, and while they take performance close to heart, it will be really hard or even impossible to reach the same speed and responsiveness. Last July Atom began using React and it gave it a nice performance boost but you can still feel the difference. Apart from that, if Atom’s performance issues will not push users away - Sublime better speed up the release cycle, brush up its small UX tweaks, and consider letting in more contributors because this is where Atom is winning.

2. Atom's package ecosystem is also growing really fast, it might not be as big as Sublime's at the moment but I have a feeling that with GitHub at it's back it will keep growing even faster. It probably has the majority of IDE like plug-ins you can think of. A major difference right now is that it can't handle files bigger than 2MB so it's something to keep in mind.

3. The one thing you'll notice first is that the Sublime minimap is gone! Other than that, the first impression is that Atom looks almost the same as Sublime. I wrote a more in depth comparison about it in this blog post.

4. No easy straightforward way to port your Sublime configurations, packages and such as far as I know.

Send the passwordbox control as a parameter to your login command.

<Button Command="{Binding LoginCommand}" CommandParameter="{Binding ElementName=PasswordBox}"...>

Then you can call CType(parameter, PasswordBox).Password in your viewmodel.

you can't use VALUES clause when inserting data using another SELECT query. see INSERT SYNTAX

INSERT INTO user
(
 id, name, username, email, opted_in
)
(
    SELECT id, name, username, email, opted_in
    FROM user
         LEFT JOIN user_permission AS userPerm
            ON user.id = userPerm.user_id
);

Here is code by AbacusUtil

LongStream.of(1, 10, 50, 80, 100, 120, 133, 333).filter(e -> e > 100).toList();

I had the same issue with VS 2019 Preview, .Net Core, and EntityFramework Core.

Turns out I had to install via NuGet Microsoft.EntityFrameworkCore.Tools and Microsoft.EntityFrameworkCore.Design. Once that was done, it worked like a charm.

In a comment on @paxdiablo's answer, you asked:

"So basically, is it better to use Double than Float?"

That is a complicated question. I will deal with it in two parts

Deciding between double versus float

On the one hand, a double occupies 8 bytes versus 4 bytes for a float. If you have many of them, this may be significant, though it may also have no impact. (Consider the case where the values are in fields or local variables on a 64bit machine, and the JVM aligns them on 64 bit boundaries.) Additionally, floating point arithmetic with double values is typically slower than with float values ... though once again this is hardware dependent.

On the other hand, a double can represent larger (and smaller) numbers than a float and can represent them with more than twice the precision. For the details, refer to Wikipedia.

The tricky question is knowing whether you actually need the extra range and precision of a double. In some cases it is obvious that you need it. In others it is not so obvious. For instance if you are doing calculations such as inverting a matrix or calculating a standard deviation, the extra precision may be critical. On the other hand, in some cases not even double is going to give you enough precision. (And beware of the trap of expecting float and double to give you an exact representation. They won't and they can't!)

There is a branch of mathematics called Numerical Analysis that deals with the effects of rounding error, etc in practical numerical calculations. It used to be a standard part of computer science courses ... back in the 1970's.

Deciding between Double versus Float

For the Double versus Float case, the issues of precision and range are the same as for double versus float, but the relative performance measures will be slightly different.

• A Double (on a 32 bit machine) typically takes 16 bytes + 4 bytes for the reference, compared with 12 + 4 bytes for a Float. Compare this to 8 bytes versus 4 bytes for the double versus float case. So the ratio is 5 to 4 versus 2 to 1.

• Arithmetic involving Double and Float typically involves dereferencing the pointer and creating a new object to hold the result (depending on the circumstances). These extra overheads also affect the ratios in favor of the Double case.

Correctness

Having said all that, the most important thing is correctness, and this typically means getting the most accurate answer. And even if accuracy is not critical, it is usually not wrong to be "too accurate". So, the simple "rule of thumb" is to use double in preference to float, UNLESS there is an overriding performance requirement, AND you have solid evidence that using float will make a difference with respect to that requirement.

Solution #1: (plain)

<a href="#!" class="someclass">Text</a>

Solution #2: (needed javascript)

<a href="javascript:void(0);" class="someclass">Text</a>

Solution #3: (needed jQuery)

<a href="#" class="someclass">Text</a>
<script>
$('a.someclass').click(function(e) {
    e.preventDefault();
});
</script>

<script type="text/javascript">
    $(document).ready(function(){
        $(".scroll-element").click(function(){
            $('html,body').animate({
                scrollTop: $('.our_companies').offset().top
            }, 1000);

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

I know this is an old question and it has already been answered, but here's another approach:

@Query("select new map(count(v) as cnt, v.answer) from Survey v group by v.answer")
public List<?> findSurveyCount();

In your main layout set your ListView gravity to right:

android:layout_gravity="right" 

Also in your code :

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.ic_drawer, R.string.drawer_open,
            R.string.drawer_close) {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                mDrawerLayout.closeDrawer(Gravity.RIGHT);
            } 
            else {
                mDrawerLayout.openDrawer(Gravity.RIGHT);
            }
        }
        return false;
    }
};

hope it works :)

I would recommend adding a boolean check for the magnitude of the number. I'm converting a high milliseconds value to datetime. I have numbers from 2 to 200,000,200 so 0 is a valid output. The function as @Chris Mueller has it will return 0 even if number is smaller than 10**n.

def get_digit(number, n):
    return number // 10**n % 10

get_digit(4231, 5)
# 0

def get_digit(number, n):
    if number - 10**n < 0:
        return False
    return number // 10**n % 10

get_digit(4321, 5)
# False

You do have to be careful when checking the boolean state of this return value. To allow 0 as a valid return value, you cannot just use if get_digit:. You have to use if get_digit is False: to keep 0 from behaving as a false value.

TensorFlow 2.3.0 works fine with CUDA 11. But you have to install tf-nightly-gpu (after you installed tensorflow and CUDA 11): https://pypi.org/project/tf-nightly-gpu/

Try:

pip install tf-nightly-gpu

Afterwards you'll get the message in your console:

I tensorflow/stream_executor/platform/default/dso_loader.cc:48] Successfully opened dynamic library cudart64_110.dll

If the shortcut ctrl+?, ctrl+shift+? or ctrl+/ is not working, try switching to another, like ctrl+1, ctrl+shift+1, it worked for me.

{ "keys": ["ctrl+1"], "command": "toggle_comment", "args": { "block": false } }, { "keys": ["ctrl+shift+1"], "command": "toggle_comment", "args": { "block": true } }

There are practical two ways to do this automaticly while only one solution can be used in all browsers. First of all you should use the open xml specification to build the excel sheet. There are free plugins from Microsoft available that make this format also available for older office versions. The open xml is standard since office 2007. The the two ways are obvious the serverside or the clientside.

The clientside implementation use a new standard of CSS that allow you to store data instead of just the URL to the data. This is a great approach coz you dont need any servercall, just the data and some javascript. The killing downside is that microsoft don't support all parts of it in the current IE (I don't know about IE9) releases. Microsoft restrict the data to be a image but we will need a document. In firefox it works quite fine. For me the IE was the killing point.

The other way is to user a serverside implementation. There should be a lot implementations of open XML for all languages. You just need to grap one. In most cases it will be the simplest way to modify a Viewmodel to result in a Document but for sure you can send all data from Clientside back to server and do the same.

Another example if you are using Titanium Alloy:

 collection.fetch({ 
     data: {
             where : JSON.stringify({
                page: 1
             })
           } 
      });

Android Studio 3

Make sure you have the latest version of Android Studio. The support library is included by default when you create new projects. If you are adding the Support Library to a project that doesn't have it, then you just need to add a single line to your app module's build.gradle file, and then sync gradle.

build.gradle

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:27.1.1'
} 

It should just be that easy, though there may be some things to note:

• Android Studio should give you a warning nowadays if the support library needs to be updated. Just update the 27.1.1 numbers that I have here to whatever it tells you to. You can also manually check what the latest revision is if you want to.
• The implementation keyword replaces compile that was used in Android Studio 2.x. (What's the difference?)
• There are other support library packages that you may need to include depending on what your app uses (like constraint-layout or recyclerview).
• Make sure that you have the latest updates for everything in the SDK Manager. Go to Tools > SDK Manager.

Documentation

• Support Library
• Support Library Setup
• Support Library Features

You can keep note of below possibilities:

1. Values entered in a map can be null.

However with multiple null keys and values it will only take a null key value pair once.

Map<String, String> codes = new HashMap<String, String>();

codes.put(null, null);
codes.put(null,null);
codes.put("C1", "Acathan");

for(String key:codes.keySet()){
    System.out.println(key);
    System.out.println(codes.get(key));
}

output will be :

null //key  of the 1st entry
null //value of 1st entry
C1
Acathan

2. your code will execute null only once

options.put(null, null);  
Person person = sample.searchPerson(null);   

It depends on the implementation of your searchPerson method if you want multiple values to be null, you can implement accordingly

Map<String, String> codes = new HashMap<String, String>();

    codes.put(null, null);
    codes.put("X1",null);
    codes.put("C1", "Acathan");
    codes.put("S1",null);


    for(String key:codes.keySet()){
        System.out.println(key);
        System.out.println(codes.get(key));
    }

output:

null
null

X1
null
S1
null
C1
Acathan

Another way is to let Eclipse do the import work for you. Hover your mouse over the com.google.android.gms import that can not be resolved and towards the bottom of the popup menu, select the Fix project setup... option as below. Then it'll prompt to import the google play services library. Select that and you should be good to go.

I came up with this extension method that includes current language features. By using dynamic, I don't need to make this a generic method and specify the type which keeps the invocation simpler and consistent:

public static class EnumEx
{
    public static dynamic Value(this Enum e)
    {
        switch (e.GetTypeCode())
        {
            case TypeCode.Byte:
            {
                return (byte) (IConvertible) e;
            }

            case TypeCode.Int16:
            {
                return (short) (IConvertible) e;
            }

            case TypeCode.Int32:
            {
                return (int) (IConvertible) e;
            }

            case TypeCode.Int64:
            {
                return (long) (IConvertible) e;
            }

            case TypeCode.UInt16:
            {
                return (ushort) (IConvertible) e;
            }

            case TypeCode.UInt32:
            {
                return (uint) (IConvertible) e;
            }

            case TypeCode.UInt64:
            {
                return (ulong) (IConvertible) e;
            }

            case TypeCode.SByte:
            {
                return (sbyte) (IConvertible) e;
            }
        }

        return 0;
    }

From the @param wiki page:

Parameters With Properties

If a parameter is expected to have a particular property, you can document that immediately after the @param tag for that parameter, like so:

 /**
  * @param userInfo Information about the user.
  * @param userInfo.name The name of the user.
  * @param userInfo.email The email of the user.
  */
 function logIn(userInfo) {

There used to be a @config tag which immediately followed the corresponding @param, but it appears to have been deprecated (example here).

There is no way.

This question is basically a duplicate of Is there a way to hide the new HTML5 spinbox controls shown in Google Chrome & Opera? but maybe not a full duplicate, since the motivation is given.

If the purpose is “browser's awareness of the content being purely numeric”, then you need to consider what that would really mean. The arrows, or spinners, are part of making numeric input more comfortable in some cases. Another part is checking that the content is a valid number, and on browsers that support HTML5 input enhancements, you might be able to do that using the pattern attribute. That attribute may also affect a third input feature, namely the type of virtual keyboard that may appear.

For example, if the input should be exactly five digits (like postal numbers might be, in some countries), then <input type="text" pattern="[0-9]{5}"> could be adequate. It is of course implementation-dependent how it will be handled.

When I don't have permission to write a file out from Postgres I find that I can run the query from the command line.

psql -U user -d db_name -c "Copy (Select * From foo_table LIMIT 10) To STDOUT With CSV HEADER DELIMITER ',';" > foo_data.csv

For large vectors:

y = as.POSIXlt(date1)$year + 1900    # x$year : years since 1900
m = as.POSIXlt(date1)$mon + 1        # x$mon : 0–11

You do not need to use ORDER BY in inner query after WHERE clause because you have already used it in ROW_NUMBER() OVER (ORDER BY VRDATE DESC).

SELECT 
    * 
FROM (
    SELECT 
        Stockmain.VRNOA, 
        item.description as item_description, 
        party.name as party_name, 
        stockmain.vrdate, 
        stockdetail.qty, 
        stockdetail.rate, 
        stockdetail.amount, 
        ROW_NUMBER() OVER (ORDER BY VRDATE DESC) AS RowNum  --< ORDER BY
    FROM StockMain 
    INNER JOIN StockDetail 
        ON StockMain.stid = StockDetail.stid 
    INNER JOIN party 
        ON party.party_id = stockmain.party_id 
    INNER JOIN item 
        ON item.item_id = stockdetail.item_id 
    WHERE stockmain.etype='purchase' 
) AS MyDerivedTable
WHERE 
    MyDerivedTable.RowNum BETWEEN 1 and 5 

I've created a version by using just a click event on the elements loaded and passing the value of the selection into the function "getSelection" and updating the model.

In your template:

<ul>
     <li *ngFor="let p of price"><input type="radio" name="price"      (click)="getValue(price.value)" value="{{p}}" #price> {{p}} 
     </li>
</ul>

Your class:

export class App {

  price:string;

  price = ["1000", "2000", "3000"];

  constructor() {   }

  model = new SomeData(this.price);

  getValue(price){
    this.model.price = price;
  }
}

See example: https://plnkr.co/edit/2Muje8yvWZVL9OXqG0pW?p=info

I solved this by installing the correct version of Jquery that my project required using npm

ES6:

Array.from(element.parentNode.children).indexOf(element)

Explanation :

• element.parentNode.children ? Returns the brothers of element, including that element.

• Array.from ? Casts the constructor of children to an Array object

• indexOf ? You can apply indexOf because you now have an Array object.

no its not like that,here is Example for the support of my answer ---->the clear difference is visible ,when you go for HTTP Compression,which allows you to compress the data while travelling from Server to Client and the Type of this data automatically becomes as "gzip" which Tells browser that bowser got a zipped data and it has to upzip it,this is a example where Type really matters at Bowser.

1. Download http://java.net/downloads/jaxb-workshop/IDE%20plugins/org.jvnet.jaxbw.zip
2. Extract the zip file .
3. Place the org.jvnet.jaxbw.eclipse_1.0.0 folder into .eclipse\plugins folder
4. Restart the eclipse.
5. Right click on XSD file and you can find contect menu. JAXB 2.0 -> Run XJC .

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's the gutsy solution. It assumes you have the actual object to test (rather than a Type).

public static Type ListOfWhat(Object list)
{
    return ListOfWhat2((dynamic)list);
}

private static Type ListOfWhat2<T>(IList<T> list)
{
    return typeof(T);
}

Example usage:

object value = new ObservableCollection<DateTime>();
ListOfWhat(value).Dump();

Prints

typeof(DateTime)

foreach(preg_split('~[\r\n]+~', $text) as $line){
    if(empty($line) or ctype_space($line)) continue; // skip only spaces
    // if(!strlen($line = trim($line))) continue; // or trim by force and skip empty
    // $line is trimmed and nice here so use it
}

^ this is how you break lines properly, cross-platform compatible with Regexp :)

This variant of it is my favourite in real life. It converts the input, if it is valid UTF-8, to the respective wstring. If the input is corrupted, the wstring is constructed out of the single bytes. This is extremely helpful if you cannot really be sure about the quality of your input data.

std::wstring convert(const std::string& input)
{
    try
    {
        std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
        return converter.from_bytes(input);
    }
    catch(std::range_error& e)
    {
        size_t length = input.length();
        std::wstring result;
        result.reserve(length);
        for(size_t i = 0; i < length; i++)
        {
            result.push_back(input[i] & 0xFF);
        }
        return result;
    }
}

In case you are using WPF and Xceed's TimePicker (which seems to be using DateTime?) as a timespan picker -as I do right now- you can get the total milliseconds (or a TimeSpan) out of it like so:

var milliseconds = DateTimeToTimeSpan(timePicker.Value).TotalMilliseconds;

    TimeSpan DateTimeToTimeSpan(DateTime? ts)
    {
        if (!ts.HasValue) return TimeSpan.Zero;
        else return new TimeSpan(0, ts.Value.Hour, ts.Value.Minute, ts.Value.Second, ts.Value.Millisecond);
    }

XAML :

<Xceed:TimePicker x:Name="timePicker" Format="Custom" FormatString="H'h 'm'm 's's'" />

If not, I guess you could just adjust my DateTimeToTimeSpan() so that it also takes 'days' into account or do sth like dateTime.Substract(DateTime.MinValue).TotalMilliseconds.

Try wrapping the spans in an anchor tag and apply the background image to that.

HTML:

<div class="header">
    <a href="/">
        <span class="header-title">My gray sea design</span><br />
        <span class="header-title-two">A beautiful design</span>
    </a>
</div>

CSS:

.header {
    border-bottom:1px solid #eaeaea;
}

.header a {
    display: block;
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;
}

I found this simple method to work the best. It does not rewrite history and all previous check-ins of branch will be appended to the master. Nothing is lost, and you can clearly see what transpired in the commit log.

Objective: Make current state of "branch" the "master"

Working on a branch, commit and push your changes to make sure your local and remote repositories are up to date:

git checkout master      # Set local repository to master
git reset --hard branch  # Force working tree and index to branch
git push origin master    # Update remote repository

After this, your master will be the exact state of your last commit of branch and your master commit log will show all check-ins of the branch.

Adding to cchana's answer. The method "length-6" fails on non-latin values in enum.

For example (the values are in Cyrillic, table is UTF8 - utf8_general_ci. In the examples I use the variable for simplicity: selecting from schema gives the same):

set @a:="enum('? ??????','?? ????????','???????')";
select substring(@a,6,length(@a)-6);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-6)                                |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????')                         |
+-------------------------------------------------------------+

Note the closing parenthesis?

select right(@a,1);
+-------------+
| right(@a,1) |
+-------------+
| )           |
+-------------+

Well, let's try remove one more character:

select substring(@a,6,length(@a)-7);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-7)                                |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????')                         |
+-------------------------------------------------------------+

No luck! The parenthesis stays in place.

Checking (mid() function works in way similar to substring(), and both shows the same results):

select mid(@a,6,length(@a)/2);
+---------------------------------------------------------+
| mid(@a,6,length(@a)/2)                                  |
+---------------------------------------------------------+
| '? ??????','?? ????????','??????                        |
+---------------------------------------------------------+

See: the string lost only three rightmost characters. But should we replace Cyrillic with Latin, and all works just perfectly:

set @b:="enum('in use','for removal','trashed')";
select (substring(@b,6,length(@b)-6));
+----------------------------------+
| (substring(@b,6,length(@b)-6))   |
+----------------------------------+
| 'in use','for removal','trashed' |
+----------------------------------+

JFYI

Edit 20210221: the solution for non-Latin characters is CHAR_LENGTH() instead of "simple" LENGTH()

The constructor of unique_ptr<T> accepts a raw pointer to an object of type T (so, it accepts a T*).

In the first example:

unique_ptr<int> uptr (new int(3));

The pointer is the result of a new expression, while in the second example:

unique_ptr<double> uptr2 (pd);

The pointer is stored in the pd variable.

Conceptually, nothing changes (you are constructing a unique_ptr from a raw pointer), but the second approach is potentially more dangerous, since it would allow you, for instance, to do:

unique_ptr<double> uptr2 (pd);
// ...
unique_ptr<double> uptr3 (pd);

Thus having two unique pointers that effectively encapsulate the same object (thus violating the semantics of a unique pointer).

This is why the first form for creating a unique pointer is better, when possible. Notice, that in C++14 we will be able to do:

unique_ptr<int> p = make_unique<int>(42);

Which is both clearer and safer. Now concerning this doubt of yours:

What is also not clear to me, is how pointers, declared in this way will be different from the pointers declared in a "normal" way.

Smart pointers are supposed to model object ownership, and automatically take care of destroying the pointed object when the last (smart, owning) pointer to that object falls out of scope.

This way you do not have to remember doing delete on objects allocated dynamically - the destructor of the smart pointer will do that for you - nor to worry about whether you won't dereference a (dangling) pointer to an object that has been destroyed already:

{
    unique_ptr<int> p = make_unique<int>(42);
    // Going out of scope...
}
// I did not leak my integer here! The destructor of unique_ptr called delete

Now unique_ptr is a smart pointer that models unique ownership, meaning that at any time in your program there shall be only one (owning) pointer to the pointed object - that's why unique_ptr is non-copyable.

As long as you use smart pointers in a way that does not break the implicit contract they require you to comply with, you will have the guarantee that no memory will be leaked, and the proper ownership policy for your object will be enforced. Raw pointers do not give you this guarantee.

Very short answer :

Different databases have different uses. I'm not a database expert. Rule of thumb:

• if you are doing analytics (ex. aggregating historical data) use OLAP
• if you are doing transactions (ex. adding/removing orders on an e-commerce cart) use OLTP

Short answer:

Let's consider two example scenarios:

Scenario 1:

You are building an online store/website, and you want to be able to:

• store user data, passwords, previous transactions...
• store actual products, their associated prices

You want to be able to find data for a particular user, change its name... basically perform INSERT, UPDATE, DELETE operations on user data. Same with products, etc.

You want to be able to make transactions, possibly involving a user buying a product (that's a relation). Then OLTP is probably a good fit.

Scenario 2:

You have an online store/website, and you want to compute things like

• the "total money spent by all users"
• "what is the most sold product"

This falls into the analytics/business intelligence domain, and therefore OLAP is probably more suited.

If you think in terms of "It would be nice to know how/what/how much"..., and that involves all "objects" of one or more kind (ex. all the users and most of the products to know the total spent) then OLAP is probably better suited.

Longer answer:

Of course things are not so simple. That's why we have to use short tags like OLTPand OLAP in the first place. Each database should be evaluated independently in the end.

So what could be the fundamental difference between OLAP and OLTP?

Well, databases have to store data somewhere. It shouldn't be surprising that the way the data is stored heavily reflects the possible use of said data. Data is usually stored on a hard drive. Let's think of a hard drive as a really wide sheet of paper, where we can read and write things. There are two ways to organize our reads and writes so that they can be efficient and fast.

One way is to make a book that is a bit like a phone book. On each page of the book, we store the information regarding a particular user. Now that's nice, we can find the information for a particular user very easily! Just jump to the page! We can even have a special page at the beginning to tell us on which page the users are if we want. But on the other hand, if we want to find, say, how much money all of our users spent then we would have to read every page, i.e. the whole book! That would be a row-based book/database (OLTP). The optional page at the beginning would be the index.

Another way to use our big sheet of paper is to make an accounting book. I'm no accountant, but let's imagine that we would have a page for "expenditures", "purchases"... That's nice because now we can query things like "give me the total revenue" very quickly (just read the "purchases" page). We can also ask for more involved things like "give me the top ten products sold" and still have acceptable performance. But now consider how painful it would be to find the expenditures for a particular user. You would have to go through the whole list of everyone's expenditures and filter the ones of that particular user, then sum them. Which basically amounts to "read the whole book" again. That would be a column-based database (OLAP).

It follows that:

• OLTP databases are meant to be used to do many small transactions, and usually serve as a "single source of truth".

• OLAP databases on the other hand are more suited for analytics, data mining, fewer queries but they are usually bigger (they operate on more data).

It's a bit more involved than that of course and that's a 20 000 feet overview of how databases differ, but it allows me not to get lost in a sea of acronyms.

Speaking of acronyms:

• OLTP = Online transaction processing
• OLAP = Online analytical processing

To read a bit further, here are some relevant links which heavily inspired my answer:

• http://datawarehouse4u.info/OLTP-vs-OLAP.html
• http://www.ibmsystemsmag.com/Blogs/You-and-i/Archive/db-102-database-orientation-row-vs-column/
• http://martinfowler.com/bliki/DataLake.html

In C, the type of a character constant like 'a' is actually an int, with size of 4 (or some other implementation-dependent value). In C++, the type is char, with size of 1. This is one of many small differences between the two languages.

public void keyPressed(KeyEvent e) {
    if (e.getKeyCode() == KeyEvent.VK_RIGHT ) {
            //Right arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_LEFT ) {
            //Left arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_UP ) {
            //Up arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_DOWN ) {
            //Down arrow key code
    }

    repaint();
}

The KeyEvent codes are all a part of the API: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html

If we have this variables:

var counter int = 5
var message string  = "Hello"
var factor float32 = 4.2
var enabled bool = false

1: fmt.Printf %T format : to use this feature you should import "fmt"

fmt.Printf("%T \n",factor )   // factor type: float32

2: reflect.TypeOf function : to use this feature you should import "reflect"

fmt.Println(reflect.TypeOf(enabled)) // enabled type:  bool

3: reflect.ValueOf(X).Kind() : to use this feature you should import "reflect"

fmt.Println(reflect.ValueOf(counter).Kind()) // counter type:  int

I had the same issue and it appears that the Node.js version was the problem.

I installed the previous version of Node.js (10.14.2) and everything was ok using nvm (allow you to install several version of Node.js and quickly switch from a version to another).

It is not a "clean" solution, but it can serve you temporarly.

This is an issue relating JRE.In my case (eclipse Luna with Maven plugin, JDK 7) I solved this by making following change in pom.xml and then Maven Update Project.

from:

 <configuration>
        <source>1.8</source>
        <target>1.8</target>
</configuration>

to:

 <configuration>
        <source>1.7</source>
        <target>1.7</target>
</configuration>

Screenshot showing problem in JRE:

You have wrong database design and you should take a time to read something about database normalization (wikipedia / stackoverflow).

I assume your table looks somewhat like this

TABLE
================================
| group_id | user_ids | name   |
--------------------------------
| 1        | 1,4,6    | group1 |
--------------------------------
| 2        | 4,5,1    | group2 |    

so in your table of user groups, each row represents one group and in user_ids column you have set of user ids assigned to that group.

Normalized version of this table would look like this

GROUP
=====================
| id       | name   |
---------------------
| 1        | group1 |
---------------------
| 2        | group2 |    

GROUP_USER_ASSIGNMENT
======================
| group_id | user_id |
----------------------
| 1        | 1       |
----------------------
| 1        | 4       |
----------------------
| 1        | 6       |
----------------------
| 2        | 4       |
----------------------
| ...      

Then you can easily select all users with assigned group, or all users in group, or all groups of user, or whatever you can think of. Also, your sql query will work:

/* Your query to select assignments */
SELECT * FROM `group_user_assignment` WHERE user_id IN (1,2,3,4);

/* Select only some users */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE user_id IN (1,4);

/* Select all groups of user */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`user_id` = 1;

/* Select all users of group */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`group_id` = 1;

/* Count number of groups user is in */
SELECT COUNT(*) AS `groups_count` FROM `group_user_assignment` WHERE `user_id` = 1;

/* Count number of users in group */
SELECT COUNT(*) AS `users_count` FROM `group_user_assignment` WHERE `group_id` = 1;

This way it will be also easier to update database, when you would like to add new assignment, you just simply insert new row in group_user_assignment, when you want to remove assignment you just delete row in group_user_assignment.

In your database design, to update assignments, you would have to get your assignment set from database, process it and update and then write back to database.

Here is sqlFiddle to play with.

Spring is great for gluing instances of classes together. You know that your Hibernate classes are always going to need a datasource, Spring wires them together (and has an implementation of the datasource too).

Your data access objects will always need Hibernate access, Spring wires the Hibernate classes into your DAOs for you.

Additionally, Spring basically gives you solid configurations of a bunch of libraries, and in that, gives you guidance in what libs you should use.

Spring is really a great tool. (I wasn't talking about Spring MVC, just the base framework).

The Y array in your screenshot is not a 1D array, it's a 2D array with 300 rows and 1 column, as indicated by its shape being (300, 1).

To remove the extra dimension, you can slice the array as Y[:, 0]. To generally convert an n-dimensional array to 1D, you can use np.reshape(a, a.size).

Another option for converting a 2D array into 1D is flatten() function from numpy.ndarray module, with the difference that it makes a copy of the array.

int yourInteger = 123450;
String s = String.format("%6.2f", yourInteger / 100.0);
System.out.println(s);

For Mac,

I fixed it by re-entering root password.

System Preferences > MYSQL > Initialize Database > Enter password

Sorry, but I think the accepted answer is an overkill. All you need to do is this:

public class ElmahHandledErrorLoggerFilter : IExceptionFilter
{
    public void OnException (ExceptionContext context)
    {
        // Log only handled exceptions, because all other will be caught by ELMAH anyway.
        if (context.ExceptionHandled)
            ErrorSignal.FromCurrentContext().Raise(context.Exception);
    }
}

and then register it (order is important) in Global.asax.cs:

public static void RegisterGlobalFilters (GlobalFilterCollection filters)
{
    filters.Add(new ElmahHandledErrorLoggerFilter());
    filters.Add(new HandleErrorAttribute());
}

Thanks to gene tsai, here is some modifications to his code to run on my target page:

csv = []
rows = $('#data tr');
for(i =0;i < rows.length;i++) {
    cells = $(rows[i]).find('td,th');
    csv_row = [];
    for (j=0;j<cells.length;j++) {
        txt = cells[j].innerText;
        csv_row.push(txt.replace(",", "-"));
    }
    csv.push(csv_row.join(","));
}
output = csv.join("\n")

improvements:

• Use generic JavaScript for loop
• make sure each cell does not have a comma

You can use array_slice as:

$sliced_array = array_slice($array,0,$N);

In your VirtualHost write the DocumentRoot to point to your Laravel Application in your home directories. In addition you must add the Directory shown below, with your own path:

<Directory /home/john/Laravel_Projects/links/public/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
    Require all granted
</Directory>

The second step, you must go to your Laravel Project and run the following command.

sudo chmod -R 777 storage bootstrap/cache

At the end restart your apache2:

sudo service apache2 restart

npm install [email protected] -g
npm install [email protected] -g

It would be easier to recreate the data frame. This would also interpret the columns types from scratch.

headers = df.iloc[0]
new_df  = pd.DataFrame(df.values[1:], columns=headers)

Year.now()

There's an easier way to use the java.time library in Java 8+. The expression:

java.time.Year.now().getValue()

returns the current year as a four-digit int, using your default time zone. There are lots of options for different time ZoneIds, Calendars and Clocks, but I think this is what you will want most of the time. If you want the code to look cleaner (and don't need any other java.time.*.now() functions), put:

import static java.time.Year.now;

at the top of your file, and call:

now().getValue()

as needed.

You may use jQuery:

<input type="text" name="IP" id="IP" value=""/>
@Html.ActionLink(@Resource.ButtonTitleAdd, "Add", "Configure", new { ipValue ="xxx", TypeId = "1" }, new {@class = "link"})

<script>
  $(function () {
    $('.link').click(function () {
      var ipvalue = $("#IP").val();
      this.href = this.href.replace("xxx", ipvalue);
    });
  });
</script>

Since you only want to remove the $ sign in all column names, you could just do:

df = df.rename(columns=lambda x: x.replace('$', ''))

OR

df.rename(columns=lambda x: x.replace('$', ''), inplace=True)

Add #pragma comment(lib, "Your library name here") to your source.

Use the literal escape character \

print("Here is, \"a quote\"")

The character basically means ignore the semantic context of my next charcter, and deal with it in its literal sense.

Modern browsers support a Content Security Policy or CSP. This is the highest level of web security and strongly recommended if you can apply it because it completely blocks all XSS attacks.

Both of your suggestions break with CSP enabled because they allow inline Javascript (which could be injected by a hacker) to execute in your page.

The best practice is to subscribe to the event in Javascript, as in Konrad Rudolph's answer.

So simple, all you need is to change the address in the config client: instead of 'localhost' change to the machine name or IP

I was facing the same problem trying to get around a custom check constraint that I needed to updated to allow different values. Problem is that ALL_CONSTRAINTS does't have a way to tell which column the constraint(s) are applied to. The way I managed to do it is by querying ALL_CONS_COLUMNS instead, then dropping each of the constraints by their name and recreate it.

select constraint_name from all_cons_columns where table_name = [TABLE_NAME] and column_name = [COLUMN_NAME];

This will work with swift 4.2, the screenshot will be saved in library, but please don't forget to edit the info.plist @ NSPhotoLibraryAddUsageDescription :

The primary key is already protecting you from inserting duplicate values, as you're experiencing when you get that error. Adding another unique constraint isn't necessary to do that.

The "duplicate key" error is telling you that the work was not done because it would produce a duplicate key, not that it discovered a duplicate key already commited to the table.

try my header here for a quick and easy way to color text: Aedi's Color Header

Escape-Sequence-Color-Header

Color Your Output in Unix using C++!!

Text Attribute Options:

ATTRIBUTES_OFF, BOLD, UNDERSCORE, BLINK, REVERSE_VIDEO, CONCEALED

Color Options:

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE

Format:

General Format, include value you want in $variable$

COLOR_$Foreground_Color$_$Background_Color$
COLOR_$Text_Attribute$_$Foreground_Color$_$Background_Color$
COLOR_NORMAL  // To set color to default

e.g.

COLOR_BLUE_BLACK // Leave Text Attribute Blank if no Text Attribute appied
COLOR_UNDERSCORE_YELLOW_RED
COLOR_NORMAL

Usage:

Just use to stream the color you want before outputting text and use again to set the color to normal after outputting text.

cout << COLOR_BLUE_BLACK << "TEXT" << COLOR_NORMAL << endl;
cout << COLOR_BOLD_YELLOW_CYAN << "TEXT" << COLOR_NORMAL << endl;

PURE JS (works also when arrays and subarrays has more than 2 elements with arbitrary order). If strings contains , use as join('-') parametr character (can be utf) which is not used in strings

array1.map(x=>x.sort()).sort().join() === array2.map(x=>x.sort()).sort().join()

var array1 = [['a', 'b'], ['b', 'c']];_x000D_
var array2 = [['b', 'c'], ['b', 'a']];_x000D_
_x000D_
var r = array1.map(x=>x.sort()).sort().join() === array2.map(x=>x.sort()).sort().join();_x000D_
_x000D_
console.log(r);

use this simple code

<input type="password" class="form-control ltr auto-complete-off" id="password" name="password" autocomplete="new-password">

You didn't join the table in your query.

Your original query will always return nothing unless there are no records at all in eotm_dyn, in which case it will return everything.

Assuming these tables should be joined on employeeID, use the following:

SELECT  *
FROM    employees e
WHERE   NOT EXISTS
        (
        SELECT  null 
        FROM    eotm_dyn d
        WHERE   d.employeeID = e.id
        )

You can join these tables with a LEFT JOIN keyword and filter out the NULL's, but this will likely be less efficient than using NOT EXISTS.

First of all insert field in your code:

<input id="reloadValue" type="hidden" name="reloadValue" value="" />

then run jQuery:

<script type="text/javascript">
   jQuery(document).ready(function()
    {
            var d = new Date();
            d = d.getTime();
            if (jQuery('#reloadValue').val().length === 0)
            {
                    jQuery('#reloadValue').val(d);
                    jQuery('body').show();
            }
            else
            {
                    jQuery('#reloadValue').val('');
                    location.reload();
            }
    });

UTF8 Option

request.DefaultRequestHeaders.Authorization = 
new AuthenticationHeaderValue(
    "Basic", Convert.ToBase64String(
        System.Text.Encoding.UTF8.GetBytes(
           $"{yourusername}:{yourpwd}")));

You have to use a custom parsing string. I also suggest to include the invariant culture to identify that this format does not relate to any culture. Plus, it will prevent a warning in some code analysis tools.

var date = DateTime.ParseExact(value, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

if you know for sure that there are only going to be 2 places where you have a list of digits in your string and that is the only thing you are going to pull out then you should be able to simply use

\d+

Here is one way of doing it:

    <%
       Dim message    
       message = "This is my message"
       Response.Write("<script language=VBScript>MsgBox """ + message + """</script>") 
    %>

Parameters are the variables received by a function.Hence they are visible in function declaration.They contain the variable name with their data type. Arguments are actual values which are passed to another function. thats why we can see them in function call. They are just values without their datatype

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

My KISS approach to skip some folders is chaining Get-ChildItem calls. This excludes root level folders but not deeper level folders if that is what you want.

Get-ChildItem -Exclude folder1,folder2 | Get-ChildItem -Recurse | ...

• Start excluding folders you don't want
• Then do the recursive search with non desired folders excluded.

What I like from this approach is that it is simple and easy to remember. If you don't want to mix folders and files in the first search a filter would be needed.

I had the same issue.

What are iml files in Android Studio project?

A Google search on iml file turns up:

IML is a module file created by IntelliJ IDEA, an IDE used to develop Java applications. It stores information about a development module, which may be a Java, Plugin, Android, or Maven component; saves the module paths, dependencies, and other settings.

(from this page)

why not to use gradle scripts to integrate with external modules that you add to your project.

You do "use gradle scripts to integrate with external modules", or your own modules.

However, Gradle is not IntelliJ IDEA's native project model — that is separate, held in .iml files and the metadata in .idea/ directories. In Android Studio, that stuff is largely generated out of the Gradle build scripts, which is why you are sometimes prompted to "sync project with Gradle files" when you change files like build.gradle. This is also why you don't bother putting .iml files or .idea/ in version control, as their contents will be regenerated.

If I have a team that work in different IDE's like Eclipse and AS how to make project IDE agnostic?

To a large extent, you can't.

You are welcome to have an Android project that uses the Eclipse-style directory structure (e.g., resources and manifest in the project root directory). You can teach Gradle, via build.gradle, how to find files in that structure. However, other metadata (compileSdkVersion, dependencies, etc.) will not be nearly as easily replicated.

Other alternatives include:

• Move everybody over to another build system, like Maven, that is equally integrated (or not, depending upon your perspective) to both Eclipse and Android Studio

• Hope that Andmore takes off soon, so that perhaps you can have an Eclipse IDE that can build Android projects from Gradle build scripts

• Have everyone use one IDE

After searching different websites looking for a solution as to how to separate the full path from the file name once the full one-piece information has been obtained from the Open File Dialog, and seeing how "complex" the solutions given were for an Excel newcomer like me, I wondered if there could be a simpler solution. So I started to work on it on my own and I came to this possibility. (I have no idea if somebody got the same idea before. Being so simple, if somebody has, I excuse myself.)

Dim fPath As String
Dim fName As String
Dim fdString As String

fdString = (the OpenFileDialog.FileName)

'Get just the path by finding the last "\" in the string from the end of it
 fPath = Left(fdString, InStrRev(fdString, "\"))

'Get just the file name by finding the last "\" in the string from the end of it
 fName = Mid(fdString, InStrRev(fdString, "\") + 1)

'Just to check the result
 Msgbox "File path: " & vbLF & fPath & vbLF & vblF & "File name: " & vbLF & fName

AND THAT'S IT!!! Just give it a try, and let me know how it goes...

The config file is just an XML file, you can open it by:

private static XmlDocument loadConfigDocument()
{
    XmlDocument doc = null;
    try
    {
        doc = new XmlDocument();
        doc.Load(getConfigFilePath());
        return doc;
    }
    catch (System.IO.FileNotFoundException e)
    {
        throw new Exception("No configuration file found.", e);
    }
    catch (Exception ex)
    {
        return null;
    }
}

and later retrieving values by:

    // retrieve appSettings node

    XmlNode node =  doc.SelectSingleNode("//appSettings");

I realize this is old, but I got here from google and after reviewing the accepted answer I did my own statement and it worked for me hope someone will find it useful:

    INSERT IGNORE INTO destTable SELECT id, field2,field3... FROM origTable

Edit: This works on MySQL I did not test on MSSQL

For your information you could use grid but with side effects :)

.parent {
  display: grid
}

to check input and get confirm by check box ,use this script...

 $(document).on("change", ".inputClass", function () {
    if($(this).is(':checked')){
     confirm_message = $(this).data('confirm');
       var confirm_status = confirm(confirm_message);
                        if (confirm_status == true) {
                           //doing somethings...
                         }
                   }});  

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label> check action </lable>
<input class="inputClass" type="checkbox" data-confirm="are u sure to do ...?" >

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

Although the accepted answer is correct, it doesn't resize Bitmap by keeping the same Aspect Ratio. If you are looking for a method to resize Bitmap by keeping the same aspect ratio you can use the following utility function. The usage details and explanation of the function are present at this link.

public static Bitmap resizeBitmap(Bitmap source, int maxLength) {
       try {
           if (source.getHeight() >= source.getWidth()) {
               int targetHeight = maxLength;
               if (source.getHeight() <= targetHeight) { // if image already smaller than the required height
                   return source;
               }

               double aspectRatio = (double) source.getWidth() / (double) source.getHeight();
               int targetWidth = (int) (targetHeight * aspectRatio);

               Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
               if (result != source) {
               }
               return result;
           } else {
               int targetWidth = maxLength;

               if (source.getWidth() <= targetWidth) { // if image already smaller than the required height
                   return source;
               }

               double aspectRatio = ((double) source.getHeight()) / ((double) source.getWidth());
               int targetHeight = (int) (targetWidth * aspectRatio);

               Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
               if (result != source) {
               }
               return result;

           }
       }
       catch (Exception e)
       {
           return source;
       }
   }

So actually, my comment that you should do a console.log(el.nativeElement) should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element.

What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el) in your example, then you'll have access to the nativeElement object and will see a property called innerHTML.

Which will lead to the answer to your original question:

let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element

Update for better approach:

Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.

The best way to manipulate DOM Elements programmatically is using the Renderer:

constructor(private _elemRef: ElementRef, private _renderer: Renderer) { 
    this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}

Edit

Since Renderer is deprecated now, use Renderer2 instead with setProperty

Update:

This question with its answer explained the console.log behavior.

Which means that console.dir(el.nativeElement) would be the more direct way of accessing the DOM Element as an "inspectable" Object in your console for this situation.

Hope this helped.

You can remove classes and add classes dynamically

$(document).ready(function(){
    $('#div').removeClass('left').addClass('right');
});

When implementing the suggestions posted here, I had trouble with the text encoding. It seems the encoding of the XmlWriterSettings is ignored, and always overridden by the encoding of the stream. When using a StringBuilder, this is always the text encoding used internally in C#, namely UTF-16.

So here's a version which supports other encodings as well.

IMPORTANT NOTE: The formatting is completely ignored if your XMLDocument object has its preserveWhitespace property enabled when loading the document. This had me stumped for a while, so make sure not to enable that.

My final code:

public static void SaveFormattedXml(XmlDocument doc, String outputPath, Encoding encoding)
{
    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Indent = true;
    settings.IndentChars = "\t";
    settings.NewLineChars = "\r\n";
    settings.NewLineHandling = NewLineHandling.Replace;

    using (MemoryStream memstream = new MemoryStream())
    using (StreamWriter sr = new StreamWriter(memstream, encoding))
    using (XmlWriter writer = XmlWriter.Create(sr, settings))
    using (FileStream fileWriter = new FileStream(outputPath, FileMode.Create))
    {
        if (doc.ChildNodes.Count > 0 && doc.ChildNodes[0] is XmlProcessingInstruction)
            doc.RemoveChild(doc.ChildNodes[0]);
        // save xml to XmlWriter made on encoding-specified text writer
        doc.Save(writer);
        // Flush the streams (not sure if this is really needed for pure mem operations)
        writer.Flush();
        // Write the underlying stream of the XmlWriter to file.
        fileWriter.Write(memstream.GetBuffer(), 0, (Int32)memstream.Length);
    }
}

This will save the formatted xml to disk, with the given text encoding.

if you want to completely empty the database and not just delete a model or models attached to it you can do:

rake db:purge

you can also do it on the test database

rake db:test:purge

I'm guessing you want to center the box both vertically and horizontally, regardless of browser window size. Since you have a fixed width and height for the box, this should work:

Markup:

<div></div>

CSS:

div {
    height: 200px;
    width: 400px;
    background: black;

    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -100px;
    margin-left: -200px;
}

The div should remain in the center of the screen even if you resize the browser. Just replace the margin-top and margin-left with half of the height and width of your table.

Edit: Credit goes to CSS-Tricks, where I got the original idea.

My favoured technique:

signal clk : std_logic := '0'; -- make sure you initialise!
...
clk <= not clk after half_period;

I usually extend this with a finished signal to allow me to stop the clock:

clk <= not clk after half_period when finished /= '1' else '0';

Gotcha alert: Care needs to be taken if you calculate half_period from another constant by dividing by 2. The simulator has a "time resolution" setting, which often defaults to nanoseconds... In which case, 5 ns / 2 comes out to be 2 ns so you end up with a period of 4ns! Set the simulator to picoseconds and all will be well (until you need fractions of a picosecond to represent your clock time anyway!)

I wrote a directive which lets you limit the areas where a click has effect. It could be used for certain scenarios like this one, so instead of having to deal with the click on a case by case basis you can just say "clicks won't come out of this element".

You would use it like this:

<table>
  <tr ng-repeat="user in users" ng-click="showUser(user)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td isolate-click>
      <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
      </button>
    </td>              
  </tr>
</table>

Keep in mind that this would prevent all clicks on the last cell, not just the button. If that's not what you want you may want to wrap the button like this:

<span isolate-click>
    <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
    </button>
</span>

Here is the directive's code:

angular.module('awesome', []).directive('isolateClick', function() {
    return {
        link: function(scope, elem) {
            elem.on('click', function(e){
                e.stopPropagation();
            });
        }
   };
});

I often used this to get the key and value inside a dictionary: (VB.Net)

Helper to fetch multiple files from a given revision

When trying to resolve merge conflicts, this helper is very useful:

#!/usr/bin/env python3

import argparse
import os
import subprocess

parser = argparse.ArgumentParser()
parser.add_argument('revision')
parser.add_argument('files', nargs='+')
args = parser.parse_args()
toplevel = subprocess.check_output(['git', 'rev-parse', '--show-toplevel']).rstrip().decode()
for path in args.files:
    file_relative = os.path.relpath(os.path.abspath(path), toplevel)
    base, ext = os.path.splitext(path)
    new_path = base + '.old' + ext
    with open(new_path, 'w') as f:
        subprocess.call(['git', 'show', '{}:./{}'.format(args.revision, path)], stdout=f)

GitHub upstream.

Usage:

git-show-save other-branch file1.c path/to/file2.cpp

Outcome: the following contain the alternate versions of the files:

file1.old.c
path/to/file2.old.cpp

This way, you keep the file extension so your editor won't complain, and can easily find the old file just next to the newer one.

Due to the complexity of determining the center of the current screen in a multi-monitor setup, an easier option is to center the pop-up over the parent window. Simply pass the parent window as another parameter:

function popupWindow(url, windowName, win, w, h) {
    const y = win.top.outerHeight / 2 + win.top.screenY - ( h / 2);
    const x = win.top.outerWidth / 2 + win.top.screenX - ( w / 2);
    return win.open(url, windowName, `toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=${w}, height=${h}, top=${y}, left=${x}`);
}

Implementation:

popupWindow('google.com', 'test', window, 200, 100);

Examples:

class Dog 
{ 
public:
    barkAt( const std::string& pOtherDog ); // const reference
    barkAt( std::string pOtherDog ); // value
};

const & is generally best. You don't incur the construction and destruction penalty. If the reference isn't const your interface is suggesting that it will change the passed in data.

If you want to export HTML to PDF. You have many options. without node even

Option 1: Have a button on your html page that calls window.print() function. use the browsers native html to pdf. use media queries to make your html page look good on a pdf. and you also have the print before and after events that you can use to make changes to your page before print.

Option 2. htmltocanvas or rasterizeHTML. convert your html to canvas , then call toDataURL() on the canvas object to get the image . and use a JavaScript library like jsPDF to add that image to a PDF file. Disadvantage of this approach is that the pdf doesnt become editable. If you want data extracted from PDF, there is different ways for that.

Option 3. @Jozzhard answer

This seems to work reliably across anything I throw at it:

function round(val, multiplesOf) {
  var s = 1 / multiplesOf;
  var res = Math.ceil(val*s)/s;
  res = res < val ? res + multiplesOf: res;
  var afterZero = multiplesOf.toString().split(".")[1];
  return parseFloat(res.toFixed(afterZero ? afterZero.length : 0));
}

It rounds up, so you may need to modify it according to use case. This should work:

console.log(round(10.01, 1)); //outputs 11
console.log(round(10.01, 0.1)); //outputs 10.1

    } 
});

This example pipes the complete contents of the repository to a file, which you can then quickly search for filenames within an editor:

svn list -R svn://svn > filelist.txt

This is useful if the repository is relatively static and you want to do rapid searches without having to repeatedly load everything from the SVN server.

This works, at least in Android API 15

ImageView = imgv;
Resources res = getResources(); // need this to fetch the drawable
Drawable draw = res.getDrawable( R.drawable.image_name_in_drawable );
imgv.setImageDrawable(draw);

You could use setImageResource(), but the documentation specifies that "does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup ... consider using setImageDrawable() or setImageBitmap()." as stated by chetto

From my HomeController I want to call this Method and convert Json response to List

No you don't. You really don't want to add the overhead of an HTTP call and (de)serialization when the code is within reach. It's even in the same assembly!

Your ApiController goes against (my preferred) convention anyway. Let it return a concrete type:

public IEnumerable<QDocumentRecord> GetAllRecords()
{
    listOfFiles = ...
    return listOfFiles;
}

If you don't want that and you're absolutely sure you need to return HttpResponseMessage, then still there's absolutely no need to bother with calling JsonConvert.SerializeObject() yourself:

return Request.CreateResponse<List<QDocumentRecord>>(HttpStatusCode.OK, listOfFiles);

Then again, you don't want business logic in a controller, so you extract that into a class that does the work for you:

public class FileListGetter
{
    public IEnumerable<QDocumentRecord> GetAllRecords()
    {
        listOfFiles = ...
        return listOfFiles;
    }
}

Either way, then you can call this class or the ApiController directly from your MVC controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var listOfFiles = new DocumentsController().GetAllRecords();
        // OR
        var listOfFiles = new FileListGetter().GetAllRecords();

        return View(listOfFiles);
    }
}

But if you really, really must do an HTTP request, you can use HttpWebRequest, WebClient, HttpClient or RestSharp, for all of which plenty of tutorials exist.

Another possibility to store numpy arrays efficiently is Bloscpack:

#!/usr/bin/python
import numpy as np
import bloscpack as bp
import time

n = 10000000

a = np.arange(n)
b = np.arange(n) * 10
c = np.arange(n) * -0.5
tsizeMB = sum(i.size*i.itemsize for i in (a,b,c)) / 2**20.

blosc_args = bp.DEFAULT_BLOSC_ARGS
blosc_args['clevel'] = 6
t = time.time()
bp.pack_ndarray_file(a, 'a.blp', blosc_args=blosc_args)
bp.pack_ndarray_file(b, 'b.blp', blosc_args=blosc_args)
bp.pack_ndarray_file(c, 'c.blp', blosc_args=blosc_args)
t1 = time.time() - t
print "store time = %.2f (%.2f MB/s)" % (t1, tsizeMB / t1)

t = time.time()
a1 = bp.unpack_ndarray_file('a.blp')
b1 = bp.unpack_ndarray_file('b.blp')
c1 = bp.unpack_ndarray_file('c.blp')
t1 = time.time() - t
print "loading time = %.2f (%.2f MB/s)" % (t1, tsizeMB / t1)

and the output for my laptop (a relatively old MacBook Air with a Core2 processor):

$ python store-blpk.py
store time = 0.19 (1216.45 MB/s)
loading time = 0.25 (898.08 MB/s)

that means that it can store really fast, i.e. the bottleneck is typically the disk. However, as the compression ratios are pretty good here, the effective speed is multiplied by the compression ratios. Here are the sizes for these 76 MB arrays:

$ ll -h *.blp
-rw-r--r--  1 faltet  staff   921K Mar  6 13:50 a.blp
-rw-r--r--  1 faltet  staff   2.2M Mar  6 13:50 b.blp
-rw-r--r--  1 faltet  staff   1.4M Mar  6 13:50 c.blp

Please note that the use of the Blosc compressor is fundamental for achieving this. The same script but using 'clevel' = 0 (i.e. disabling compression):

$ python bench/store-blpk.py
store time = 3.36 (68.04 MB/s)
loading time = 2.61 (87.80 MB/s)

is clearly bottlenecked by the disk performance.

Just a thought:

public static string Right(this string @this, int length) {
    return @this.Substring(Math.Max(@this.Length - length, 0));
}

I just encountered this and whilst we already had .NET 4.0 installed on the server it turns out we only had the "Client Profile" version and not the "Full" version. Installing the latter fixed the problem.

James K, I'm sorry I was wrong in a fair portion of what I said. The test I did was the following:

@ECHO OFF
(
  :: But
   : neither
  :: does
   : this
  :: also.
)

This meets your description of alternating but fails with a ") was unexpected at this time." error message.

I did some farther testing today and found that alternating isn't the key but it appears the key is having an even number of lines, not having any two lines in a row starting with double colons (::) and not ending in double colons. Consider the following:

@ECHO OFF
(
   : But
   : neither
   : does
   : this
   : cause
   : problems.
)

This works!

But also consider this:

@ECHO OFF
(
   : Test1
   : Test2
   : Test3
   : Test4
   : Test5
   ECHO.
)

The rule of having an even number of comments doesn't seems to apply when ending in a command.

Unfortunately this is just squirrelly enough that I'm not sure I want to use it.

Really, the best solution, and the safest that I can think of, is if a program like Notepad++ would read REM as double colons and then would write double colons back as REM statements when the file is saved. But I'm not aware of such a program and I'm not aware of any plugins for Notepad++ that does that either.

My preference is to utilize the inline attribute. This will cause the icon to correctly scale with the size of the button.

    <button mat-button>
      <mat-icon inline=true>local_movies</mat-icon>
      Movies
    </button>

    <!-- Link button -->
    <a mat-flat-button color="accent" routerLink="/create"><mat-icon inline=true>add</mat-icon> Create</a>

I add this to my styles.css to:

• solve the vertical alignment problem of the icon inside the button
• material icon fonts are always a little too small compared to button text

button.mat-button .mat-icon,
a.mat-button .mat-icon,
a.mat-raised-button .mat-icon,
a.mat-flat-button .mat-icon,
a.mat-stroked-button .mat-icon {
  vertical-align: top;
  font-size: 1.25em;
}

A hack to give the appearance of margins between table rows is to give them a border the same color as the background. This is useful when styling a 3rd party theme where you can't change the html markup. Eg:

tr{ 
    border: 5px solid white;
}

Any one on windows 10 Pro , this is for you guys --

1. Open CMD in administrator mode .

2. Paste below code-

   RD /S /Q "%WinDir%\System32\GroupPolicyUsers" 
   RD /S /Q "%WinDir%\System32\GroupPolicy" 
   gpupdate /force
   

3. After few seconds you will see this -

   User Policy update has completed successfully.
   Computer Policy update has completed successfully.
   

4. Now you can change your search engine to whatever you want.

Thank you

In case, you want to keep old field (For ex: name). The query will be:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name=name, age=19;

How about a dict comprehension:

filtered_dict = {k:v for k,v in d.iteritems() if filter_string in k}

One you see it, it should be self-explanatory, as it reads like English pretty well.

This syntax requires Python 2.7 or greater.

In Python 3, there is only dict.items(), not iteritems() so you would use:

filtered_dict = {k:v for (k,v) in d.items() if filter_string in k}

Was asked here before: Unix command to find lines common in two files

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

If your end goal is to add elements to your page, just manipulate the DOM directly. Don't use string concatenation to try to create HTML - what a pain! See how much more straightforward it is to just create your element, instead of the HTML that represents your element:

var x = document.createElement("option");
x.value = col;
x.text = "Very roomy";
x.selected = col == "screwdriver";

Then, later when you put the element in your page, instead of setting the innerHTML of the parent element, call appendChild():

mySelectElement.appendChild(x);

You JSON is not a valid string as P. Galbraith has told you above.

and here is the solution for it.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

Use this code it will work for you.

Go to "Target" -> "Build Phases", select your target, select the “Build Phases” tab, click “Add Build Phase”, and select “Add Copy Files”. Change the destination to “Products Directory”. Drag your file into the “Add files” section.

sep='' in the context of a function call sets the named argument sep to an empty string. See the print() function; sep is the separator used between multiple values when printing. The default is a space (sep=' '), this function call makes sure that there is no space between Property tax: $ and the formatted tax floating point value.

Compare the output of the following three print() calls to see the difference

>>> print('foo', 'bar')
foo bar
>>> print('foo', 'bar', sep='')
foobar
>>> print('foo', 'bar', sep=' -> ')
foo -> bar

All that changed is the sep argument value.

\t in a string literal is an escape sequence for tab character, horizontal whitespace, ASCII codepoint 9.

\t is easier to read and type than the actual tab character. See the table of recognized escape sequences for string literals.

Using a space or a \t tab as a print separator shows the difference:

>>> print('eggs', 'ham')
eggs ham
>>> print('eggs', 'ham', sep='\t')
eggs    ham

Just as normal, using data-original-title:

Html:

<div rel='tooltip' data-original-title='<h1>big tooltip</h1>'>Visible text</div>

Javascript:

$("[rel=tooltip]").tooltip({html:true});

The html parameter specifies how the tooltip text should be turned into DOM elements. By default Html code is escaped in tooltips to prevent XSS attacks. Say you display a username on your site and you show a small bio in a tooltip. If the html code isn't escaped and the user can edit the bio themselves they could inject malicious code.

I've tweaked the source posted in the question to allow usage with Google's TTS API in order to answer the question here:

bool waiting = false;
AutoResetEvent stop = new AutoResetEvent(false);
public void PlayMp3FromUrl(string url, int timeout)
{
    using (Stream ms = new MemoryStream())
    {
        using (Stream stream = WebRequest.Create(url)
            .GetResponse().GetResponseStream())
        {
            byte[] buffer = new byte[32768];
            int read;
            while ((read = stream.Read(buffer, 0, buffer.Length)) > 0)
            {
                ms.Write(buffer, 0, read);
            }
        }
        ms.Position = 0;
        using (WaveStream blockAlignedStream =
            new BlockAlignReductionStream(
                WaveFormatConversionStream.CreatePcmStream(
                    new Mp3FileReader(ms))))
        {
            using (WaveOut waveOut = new WaveOut(WaveCallbackInfo.FunctionCallback()))
            {
                waveOut.Init(blockAlignedStream);
                waveOut.PlaybackStopped += (sender, e) =>
                {
                    waveOut.Stop();
                };
                waveOut.Play();
                waiting = true;
                stop.WaitOne(timeout);
                waiting = false;
            }
        }
    }
}

Invoke with:

var playThread = new Thread(timeout => PlayMp3FromUrl("http://translate.google.com/translate_tts?q=" + HttpUtility.UrlEncode(relatedLabel.Text), (int)timeout));
playThread.IsBackground = true;
playThread.Start(10000);

Terminate with:

if (waiting)
    stop.Set();

Notice that I'm using the ParameterizedThreadDelegate in the code above, and the thread is started with playThread.Start(10000);. The 10000 represents a maximum of 10 seconds of audio to be played so it will need to be tweaked if your stream takes longer than that to play. This is necessary because the current version of NAudio (v1.5.4.0) seems to have a problem determining when the stream is done playing. It may be fixed in a later version or perhaps there is a workaround that I didn't take the time to find.

Generally, you can use the func(*tuple) syntax. You can even pass a part of the tuple, which seems like what you're trying to do here:

t = (2010, 10, 2, 11, 4, 0, 2, 41, 0)
dt = datetime.datetime(*t[0:7])

This is called unpacking a tuple, and can be used for other iterables (such as lists) too. Here's another example (from the Python tutorial):

>>> range(3, 6)             # normal call with separate arguments
[3, 4, 5]
>>> args = [3, 6]
>>> range(*args)            # call with arguments unpacked from a list
[3, 4, 5]

I wanted to use an xml control file based on a class for my VB.net desktop WPF application. The above code to do this all in one is excellent and set me in the right direction. In case anyone is searching for a VB.net solution here is the class I built:

Imports System.IO
Imports System.Xml.Serialization

Public Class XControl

Private _person_ID As Integer
Private _person_UID As Guid

'load from file
Public Function XCRead(filename As String) As XControl
    Using sr As StreamReader = New StreamReader(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        Return CType(xmls.Deserialize(sr), XControl)
    End Using
End Function

'save to file
Public Sub XCSave(filename As String)
    Using sw As StreamWriter = New StreamWriter(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        xmls.Serialize(sw, Me)
    End Using
End Sub

'all the get/set is below here

Public Property Person_ID() As Integer
    Get
        Return _person_ID
    End Get
    Set(value As Integer)
        _person_ID = value
    End Set
End Property

Public Property Person_UID As Guid
    Get
        Return _person_UID
    End Get
    Set(value As Guid)
        _person_UID = value
    End Set
End Property

End Class

grid.store = store;
store.load({ params: { start: 0, limit: 20} });
grid.getView().refresh();

In addition to the other answers, which I subscribe, you may consider using the /I switch of the IF command.

... the /I switch, if specified, says to do case insensitive string compares.

it may be of help if you want to give case insensitive flexibility to your users to specify the parameters.

IF /I "%1"=="-b" GOTO SPECIFIC

A better approach is to let Retrofit generate POJO for you from the json (using gson). First thing is to add .addConverterFactory(GsonConverterFactory.create()) when creating your Retrofit instance. For example, if you had a User java class (such as shown below) that corresponded to your json, then your retrofit api could return Call<User>

class User {
    private String id;
    private String Username;
    private String Level;
    ...
}    

You don't want a string, you really want a JS map of key value pairs. E.g., change:

 data: myDataVar.toString(),

with:

var myKeyVals = { A1984 : 1, A9873 : 5, A1674 : 2, A8724 : 1, A3574 : 3, A1165 : 5 }



var saveData = $.ajax({
      type: 'POST',
      url: "someaction.do?action=saveData",
      data: myKeyVals,
      dataType: "text",
      success: function(resultData) { alert("Save Complete") }
});
saveData.error(function() { alert("Something went wrong"); });

jQuery understands key value pairs like that, it does NOT understand a big string. It passes it simply as a string.

UPDATE: Code fixed.

It is varchar and not var_char

CREATE DATABASE IF NOT EXISTS courses;

USE courses;

CREATE TABLE IF NOT EXISTS teachers(
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    addr VARCHAR(255) NOT NULL,
    phone INT NOT NULL
);

You should use a SQL tool to visualize possbile errors like MySQL Workbench.

If you are mainly interested in implementing logic to the setter only:

import { Component, Input, OnChanges, SimpleChanges } from '@angular/core';

// [...]

export class MyClass implements OnChanges {
  @Input() allowDay: boolean;

  ngOnChanges(changes: SimpleChanges): void {
    if(changes['allowDay']) {
      this.updatePeriodTypes();
    }
  }
}

The import of SimpleChanges is not needed if it doesn't matter which input property was changed or if you have only one input property.

Angular Doc: OnChanges

otherwise:

private _allowDay: boolean;

@Input() set allowDay(value: boolean) {
  this._allowDay = value;
  this.updatePeriodTypes();
}
get allowDay(): boolean {
  // other logic
  return this._allowDay;
}

If you want to put the environment for system-wide use you can do so with /etc/environment file.

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

I had this issue once. It turned out to be database query issue. After re-create tables and index it has been fixed.

Although it says proxy error, when you look at server log, it shows execute query timeout. This is what I had before and how I solved it.

just use -

if(!a) // if a is negative,undefined,null,empty value then...
{
    // do whatever
}
else {
    // do whatever
}

this works because of the == difference from === in javascript, which converts some values to "equal" values in other types to check for equality, as opposed for === which simply checks if the values equal. so basically the == operator know to convert the "", null, undefined to a false value. which is exactly what you need.

In case you are using RabbitMQ with Docker your steps should be:

1. Connect to container: docker exec -it your_container_id bash
2. rabbitmqctl purge_queue Queue-1 (where Queue-1 is queue name)

I have been trying to do the same myself. What I found was that the "Export Ant Buildfile" gets kicked off in the org.eclipse.ant.internal.ui.datatransfer.AntBuildfileExportPage.java file. This resides in the org.eclipse.ant.ui plugin.

To view the source, use the Plug-in Development perspective and open the Plug-ins view. Then right-click on the org.eclipse.ant.ui plugin and select import as > source project.

My plan is to create a Java program to programmatically kick off the ant buildfile generation and call this in an Ant file every time I build by adding the ant file to the builders of my projects (Right-click preferences on a projet, under the builders tab).

I had this problem today. I fixed it being being explict about my require

gem 'uglifier', '>= 1.0.3', require: 'uglifier'

I had mine still in the assets group.

Python dictionaries don't support duplicate keys. One way around is to store lists or sets inside the dictionary.

One easy way to achieve this is by using defaultdict:

from collections import defaultdict

data_dict = defaultdict(list)

All you have to do is replace

data_dict[regNumber] = details

with

data_dict[regNumber].append(details)

and you'll get a dictionary of lists.

One good example of when to use something like this is with Java Simple Serial Connector, accessing serial ports. Typically you'll write something to the port, and asyncronously, on another thread, the device will respond on a SerialPortEventListener. Typically, you'll want to pause after writing to the port to wait for the response. Handling the thread locks for this scenario manually is extremely tricky, but using Countdownlatch is easy. Before you go thinking you can do it another way, be careful about race conditions you never thought of!!

Pseudocode:

CountDownLatch latch;
void writeData() { 
   latch = new CountDownLatch(1);
   serialPort.writeBytes(sb.toString().getBytes())
   try {
      latch.await(4, TimeUnit.SECONDS);
    } catch (InterruptedException e) {
   }
}
class SerialPortReader implements SerialPortEventListener {
    public void serialEvent(SerialPortEvent event) {
        if(event.isRXCHAR()){//If data is available
            byte buffer[] = serialPort.readBytes(event.getEventValue());
            latch.countDown();
         }
     }
}

As for second question - you can use Fiddler filters to set response X-Frame-Options header manually to something like ALLOW-FROM *. But, of course, this trick will work only for you - other users still won't be able to see iframe content(if they not do the same).

If you work in IntelliJ, there are four independent ways to refresh maven repositories. Each of them refreshes another local repository on your computer or refreshes them differently.

1. mvn -U clean install
2. Ctrl+Shift+A - Reimport
3. Round arrows in the Maven window

4. Ctrl+Alt+S , go to Build, Execution, Deployment | Build Tools | Maven | Repositories -choose rep - update

What is interesting, it is often said, that the last refresh is equal to the round arrows in the Maven window. But, according to my experience, they are absolutely different! The proof: Our large project fails the last refresh, but exists and runs happily without it. And double round arrows run OK on it.

Each of these four can help you with your problems or/and find problems of its own. For example, for running our real-life project only the first is necessary, but for testing in IntelliJ we also need 2 and 3. Surely, somebody needs 4, too. (Why else IntelliJ has it?)

Query string parameters can be accepted simply by using an argument on the action - i.e.

public ActionResult Foo(string someValue, int someOtherValue) {...}

which will accept a query like .../someroute?someValue=abc&someOtherValue=123

Other than that, you can look at the request directly for more control.

You can try it by adding  

If you are using SQL Server try this:

SELECT * FROM MyTable
WHERE MyDate < DATEADD(month, -2, GETDATE())

Based on your update it would be:

SELECT * FROM FB WHERE Dte <  DATEADD(month, -2, GETDATE())

Sorry for reviving really old question but as it is listed among first google search results I assume that some people keep landing here.

Among a lot of answers, some of them really valuable and well explained, I would like to add a different point of vue as, to me, the problem has not be well identified.

You are declaring a variable which stores data, you need it to be able to change by adding items to it ? So you shouldn't use declare it as IEnumerable.

As proposed by @NightOwl888

For this example, just declare IList instead of IEnumerable: IList items = new T[]{new T("msg")}; items.Add(new T("msg2"));

Trying to bypass the declared interface limitations only shows that you made the wrong choice. Beyond this, all methods that are proposed to implement things that already exists in other implementations should be deconsidered. Classes and interfaces that let you add items already exists. Why always recreate things that are already done elsewhere ?

This kind of consideration is a goal of abstracting variables capabilities within interfaces.

TL;DR : IMO these are cleanest ways to do what you need :

// 1st choice : Changing declaration
IList<T> variable = new T[] { };
variable.Add(new T());

// 2nd choice : Changing instantiation, letting the framework taking care of declaration
var variable = new List<T> { };
variable.Add(new T());

When you'll need to use variable as an IEnumerable, you'll be able to. When you'll need to use it as an array, you'll be able to call 'ToArray()', it really always should be that simple. No extension method needed, casts only when really needed, ability to use LinQ on your variable, etc ...

Stop doing weird and/or complex things because you only made a mistake when declaring/instantiating.

try this

namespace dateandtime
{

    class DatesTime
    {

        public static DateTime Substract(DateTime now, int hours,int minutes,int seconds)
        {
            TimeSpan T1 = new TimeSpan(hours, minutes, seconds);
            return now.Subtract(T1);
        }


        static void Main(string[] args)
        {
            Console.WriteLine(Substract(DateTime.Now, 36, 0, 0).ToString());

        }
    }
}

I tried the solution below

class Crontab {

// In this class, array instead of string would be the standard input / output format.

// Legacy way to add a job:
// $output = shell_exec('(crontab -l; echo "'.$job.'") | crontab -');

static private function stringToArray($jobs = '') {
    $array = explode("\r\n", trim($jobs)); // trim() gets rid of the last \r\n
    foreach ($array as $key => $item) {
        if ($item == '') {
            unset($array[$key]);
        }
    }
    return $array;

You should call this function from the controller.

angular.module('App', [])
  .controller('CinemaCtrl', ['$scope', function($scope) {
    myFunction();
  }]);

Even with normal javascript/html your function won't run on page load as all your are doing is defining the function, you never call it. This is really nothing to do with angular, but since you're using angular the above would be the "angular way" to invoke the function.

Obviously better still declare the function in the controller too.

Edit: Actually I see your "onload" - that won't get called as angular injects the HTML into the DOM. The html is never "loaded" (or the page is only loaded once).

If I understand you correctly, yes you can, but not under Visual Studio (from what I know). To force the compiler to generate a real, standalone executable (which means you use C# like any other language) you use the program mkbundle (shipped with Mono). This will compile your C# app into a real, no dependency executable.

There is a lot of misconceptions about this around the internet. It does not defeat the purpose of the .net framework like some people state, because how can you lose future features of the .net framework if you havent used these features to begin with? And when you ship updates to your app, it's not exactly hard work to run it through the mkbundle processor before building your installer. There is also a speed benefit involved making your app run at native speed (because now it IS native).

In C++ or Delphi you have the same system, but without the middle MSIL layer. So if you use a namespace or sourcefile (called a unit under Delphi), then it's compiled and included in your final binary. So your final binary will be larger (Read: "Normal" size for a real app). The same goes for the parts of the framework you use in .net, these are also included in your app. However, smart linking does shave a conciderable amount.

Hope it helps!

Usually I try to follow the next pattern:

• static members (have usually an other context, must be thread-safe, etc.)
• instance members

Each part (static and instance) consists of the following member types:

• operators (are always static)
• fields (initialized before constructors)
• constructors
• destructor (is a tradition to follow the constructors)
• properties
• methods
• events

Then the members are sorted by visibility (from less to more visible):

• private
• internal
• internal protected
• protected
• public

The order is not a dogma: simple classes are easier to read, however, more complex classes need context-specific grouping.

$('#selector').is(':visible');

If you're going to access your local computer (or any computer) using UNC, you'll need to setup a share. If you haven't already setup a share, you could use the default administrative shares. Example:

\\localhost\c$\my_dir

... accesses a folder called "my_dir" via UNC on your C: drive. By default all the hard drives on your machine are shared with hidden shares like c$, d$, etc.

Try =index(ARRAY, ROW, COLUMN)

where: Array: select the whole sheet Row, Column: Your row and column references

That should be easier to understand to those looking at the formula.

To fix this below error, I did enough research, not got any great solution, I prepared this script and it is working fine, thought to share to the public and make use of it and save there time.

CreateProcess error=206, The filename or extension is too long

If you are using the Gradle build tool, and the executable file is placed in build/libs directory of your application. run.sh -> create this file in the root directory of your project, and copy below script in it, then go to git bash and type run.sh then enter. Hope this helps!

In C++ 17 you can use inline variables:

class A {
 private:
  static inline const std::string my_string = "some useful string constant";
};

Note that this is different from abyss.7's answer: This one defines an actual std::string object, not a const char*

JDK 9 has added InputStream#transferTo(OutputStream out) for this functionality.

There is no do-while loop in Python.

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

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

This is the 2nd of two answers.

If you want to just strip all namespaces arbitrarily from a document during serialization, you can do this by implementing your own XmlWriter.

The easiest way is to derive from XmlTextWriter and override the StartElement method that emits namespaces. The StartElement method is invoked by the XmlSerializer when emitting any elements, including the root. By overriding the namespace for each element, and replacing it with the empty string, you've stripped the namespaces from the output.

public class NoNamespaceXmlWriter : XmlTextWriter
{
    //Provide as many contructors as you need
    public NoNamespaceXmlWriter(System.IO.TextWriter output)
        : base(output) { Formatting= System.Xml.Formatting.Indented;}

    public override void WriteStartDocument () { }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        base.WriteStartElement("", localName, "");
    }
}

Suppose this is the type:

// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
    // private fields backing the properties
    private int _Epoch;
    private string _Label;

    // explicitly define a distinct namespace for this element
    [XmlElement(Namespace="urn:Whoohoo")]
    public string Label
    {
        set {  _Label= value; } 
        get { return _Label; } 
    }

    // this property will be implicitly serialized to XML using the
    // member name for the element name, and inheriting the namespace from
    // the type.
    public int Epoch
    {
        set {  _Epoch= value; } 
        get { return _Epoch; } 
    }
}

Here's how you would use such a thing during serialization:

        var o2= new MyTypeWithNamespaces { ..intializers.. };
        var builder = new System.Text.StringBuilder();
        using ( XmlWriter writer = new NoNamespaceXmlWriter(new System.IO.StringWriter(builder)))
        {
            s2.Serialize(writer, o2, ns2);
        }            
        Console.WriteLine("{0}",builder.ToString());

The XmlTextWriter is sort of broken, though. According to the reference doc, when it writes it does not check for the following:

• Invalid characters in attribute and element names.

• Unicode characters that do not fit the specified encoding. If the Unicode characters do not fit the specified encoding, the XmlTextWriter does not escape the Unicode characters into character entities.

• Duplicate attributes.

• Characters in the DOCTYPE public identifier or system identifier.

These problems with XmlTextWriter have been around since v1.1 of the .NET Framework, and they will remain, for backward compatibility. If you have no concerns about those problems, then by all means use the XmlTextWriter. But most people would like a bit more reliability.

To get that, while still suppressing namespaces during serialization, instead of deriving from XmlTextWriter, define a concrete implementation of the abstract XmlWriter and its 24 methods.

An example is here:

public class XmlWriterWrapper : XmlWriter
{
    protected XmlWriter writer;

    public XmlWriterWrapper(XmlWriter baseWriter)
    {
        this.Writer = baseWriter;
    }

    public override void Close()
    {
        this.writer.Close();
    }

    protected override void Dispose(bool disposing)
    {
        ((IDisposable) this.writer).Dispose();
    }

    public override void Flush()
    {
        this.writer.Flush();
    }

    public override string LookupPrefix(string ns)
    {
        return this.writer.LookupPrefix(ns);
    }

    public override void WriteBase64(byte[] buffer, int index, int count)
    {
        this.writer.WriteBase64(buffer, index, count);
    }

    public override void WriteCData(string text)
    {
        this.writer.WriteCData(text);
    }

    public override void WriteCharEntity(char ch)
    {
        this.writer.WriteCharEntity(ch);
    }

    public override void WriteChars(char[] buffer, int index, int count)
    {
        this.writer.WriteChars(buffer, index, count);
    }

    public override void WriteComment(string text)
    {
        this.writer.WriteComment(text);
    }

    public override void WriteDocType(string name, string pubid, string sysid, string subset)
    {
        this.writer.WriteDocType(name, pubid, sysid, subset);
    }

    public override void WriteEndAttribute()
    {
        this.writer.WriteEndAttribute();
    }

    public override void WriteEndDocument()
    {
        this.writer.WriteEndDocument();
    }

    public override void WriteEndElement()
    {
        this.writer.WriteEndElement();
    }

    public override void WriteEntityRef(string name)
    {
        this.writer.WriteEntityRef(name);
    }

    public override void WriteFullEndElement()
    {
        this.writer.WriteFullEndElement();
    }

    public override void WriteProcessingInstruction(string name, string text)
    {
        this.writer.WriteProcessingInstruction(name, text);
    }

    public override void WriteRaw(string data)
    {
        this.writer.WriteRaw(data);
    }

    public override void WriteRaw(char[] buffer, int index, int count)
    {
        this.writer.WriteRaw(buffer, index, count);
    }

    public override void WriteStartAttribute(string prefix, string localName, string ns)
    {
        this.writer.WriteStartAttribute(prefix, localName, ns);
    }

    public override void WriteStartDocument()
    {
        this.writer.WriteStartDocument();
    }

    public override void WriteStartDocument(bool standalone)
    {
        this.writer.WriteStartDocument(standalone);
    }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        this.writer.WriteStartElement(prefix, localName, ns);
    }

    public override void WriteString(string text)
    {
        this.writer.WriteString(text);
    }

    public override void WriteSurrogateCharEntity(char lowChar, char highChar)
    {
        this.writer.WriteSurrogateCharEntity(lowChar, highChar);
    }

    public override void WriteValue(bool value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(DateTime value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(decimal value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(double value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(int value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(long value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(object value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(float value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteValue(string value)
    {
        this.writer.WriteValue(value);
    }

    public override void WriteWhitespace(string ws)
    {
        this.writer.WriteWhitespace(ws);
    }


    public override XmlWriterSettings Settings
    {
        get
        {
            return this.writer.Settings;
        }
    }

    protected XmlWriter Writer
    {
        get
        {
            return this.writer;
        }
        set
        {
            this.writer = value;
        }
    }

    public override System.Xml.WriteState WriteState
    {
        get
        {
            return this.writer.WriteState;
        }
    }

    public override string XmlLang
    {
        get
        {
            return this.writer.XmlLang;
        }
    }

    public override System.Xml.XmlSpace XmlSpace
    {
        get
        {
            return this.writer.XmlSpace;
        }
    }        
}

Then, provide a derived class that overrides the StartElement method, as before:

public class NamespaceSupressingXmlWriter : XmlWriterWrapper
{
    //Provide as many contructors as you need
    public NamespaceSupressingXmlWriter(System.IO.TextWriter output)
        : base(XmlWriter.Create(output)) { }

    public NamespaceSupressingXmlWriter(XmlWriter output)
        : base(XmlWriter.Create(output)) { }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        base.WriteStartElement("", localName, "");
    }
}

And then use this writer like so:

        var o2= new MyTypeWithNamespaces { ..intializers.. };
        var builder = new System.Text.StringBuilder();
        var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent= true };
        using ( XmlWriter innerWriter = XmlWriter.Create(builder, settings))
            using ( XmlWriter writer = new NamespaceSupressingXmlWriter(innerWriter))
            {
                s2.Serialize(writer, o2, ns2);
            }            
        Console.WriteLine("{0}",builder.ToString());

Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;

This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79.

I came across the same problem when using eclipse-jee. I found the reason of this problem is that I had two or more duplicate @WebServlet("/yourServlet") definition in my web-app,so solution is to eliminate duplicates

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

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

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

Often data on webpages is in the form of an XML table. You can read an XML table into R using the package XML.

In this package, the function

readHTMLTable(<url>)

will look through a page for XML tables and return a list of data frames (one for each table found).

Copy Schema (Generate DDL) through SSMS UI

In SSMS expand your database in Object Explorer, go to Tables, right click on the table you're interested in and select Script Table As, Create To, New Query Editor Window. Do a find and replace (CTRL + H) to change the table name (i.e. put ABC in the Find What field and ABC_1 in the Replace With then click OK).

Copy Schema through T-SQL

The other answers showing how to do this by SQL also work well, but the difference with this method is you'll also get any indexes, constraints and triggers.

Copy Data

If you want to include data, after creating this table run the below script to copy all data from ABC (keeping the same ID values if you have an identity field):

set identity_insert ABC_1 on
insert into ABC_1 (column1, column2) select column1, column2 from ABC
set identity_insert ABC_1 off

If the files already have the +x flag set, git update-index --chmod=+x does nothing and git thinks there's nothing to commit, even though the flag isn't being saved into the repo.

You must first remove the flag, run the git command, then put the flag back:

chmod -x <file>
git update-index --chmod=+x <file>
chmod +x <file>

then git sees a change and will allow you to commit the change.

Using hanoo's script I created a jQuery function:

$.fn.scrollIntoView = function(duration, easing) {
    var dest = 0;
    if (this.offset().top > $(document).height() - $(window).height()) {
        dest = $(document).height() - $(window).height();
    } else {
        dest = this.offset().top;
    }
    $('html,body').animate({
        scrollTop: dest
    }, duration, easing);
    return this;
};

usage:

$('#myelement').scrollIntoView();

Defaults for duration and easing are 400ms and "swing".
