I wrote jaguarDb to handle some of the things that you are mentioning since I sometimes need a "little" database for demo or test projects too and I don't want to depend on mongoDB or another real database.

Another way:

a xls(x) file is just a collection of *.xml files stored in a *.zip container. unzip the file "app.xml" in the folder docProps.

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

The file is a german file (Arbeitsblätter = worksheets). The table names (Tabelle3 etc) are in the correct order. You just need to read these tags;)

JSONP is a way of getting around the browser's same-origin policy. How? Like this:

The goal here is to make a request to otherdomain.com and alert the name in the response. Normally we'd make an AJAX request:

$.get('otherdomain.com', function (response) {
  var name = response.name;
  alert(name);
});

However, since the request is going out to a different domain, it won't work.

We can make the request using a <script> tag though. Both <script src="otherdomain.com"></script> and $.get('otherdomain.com') will result in the same request being made:

GET otherdomain.com

Q: But if we use the <script> tag, how could we access the response? We need to access it if we want to alert it.

A: Uh, we can't. But here's what we could do - define a function that uses the response, and then tell the server to respond with JavaScript that calls our function with the response as its argument.

Q: But what if the server won't do this for us, and is only willing to return JSON to us?

A: Then we won't be able to use it. JSONP requires the server to cooperate.

Q: Having to use a <script> tag is ugly.

A: Libraries like jQuery make it nicer. Ex:

$.ajax({
    url: "http://otherdomain.com",
    jsonp: "callback",
    dataType: "jsonp",
    success: function( response ) {
        console.log( response );
    }
});

It works by dynamically creating the <script> tag DOM element.

Q: <script> tags only make GET requests - what if we want to make a POST request?

A: Then JSONP won't work for us.

Q: That's ok, I just want to make a GET request. JSONP is awesome and I'm going to go use it - thanks!

A: Actually, it isn't that awesome. It's really just a hack. And it isn't the safest thing to use. Now that CORS is available, you should use it whenever possible.

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.

To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY

I have added an extra update method onto my repository base class that's similar to the update method generated by Scaffolding. Instead of setting the entire object to "modified", it sets a set of individual properties. (T is a class generic parameter.)

public void Update(T obj, params Expression<Func<T, object>>[] propertiesToUpdate)
{
    Context.Set<T>().Attach(obj);

    foreach (var p in propertiesToUpdate)
    {
        Context.Entry(obj).Property(p).IsModified = true;
    }
}

And then to call, for example:

public void UpdatePasswordAndEmail(long userId, string password, string email)
{
    var user = new User {UserId = userId, Password = password, Email = email};

    Update(user, u => u.Password, u => u.Email);

    Save();
}

I like one trip to the database. Its probably better to do this with view models, though, in order to avoid repeating sets of properties. I haven't done that yet because I don't know how to avoid bringing the validation messages on my view model validators into my domain project.

You forgot the return types in your member function definitions:

int ttTree::ttTreeInsert(int value) { ... }
^^^               

and so on.

There's a nice article with code on this topic on MSDN. I'm assuming that setting the Style property to ProgressBarStyle.Marquee is not appropriate (or is that what you are trying to control?? -- I don't think it is possible to stop/start this animation although you can control the speed as @Paul indicates).

Same basic solution as others, but I personally prefer to use map instead of the list comprehension:

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(map(chr,L))
'hello, world'

Assuming you have a song class (you can refer below), the traditional implementation would be like as follows

 class Song
  {
       private String author_name;
       public String setauthorname(String X) {}; //implementation goes here
       public String getauthorname() {}; //implementation goes here
  }

Now, consider this class implementation.

      class Song 
      {
            private String author_name;
            public String Author_Name
            { 
                 get { return author_name; }
                set { author_name= value; }
             }
      }

In your 'Main' class, you will wrote your code as

    class TestSong
    { 
      public static void Main(String[] Args)
      {
          Song _song = new Song(); //create an object for class 'Song'    
          _song.Author_Name = 'John Biley';
          String author = _song.Author_Name;           
          Console.WriteLine("Authorname = {0}"+author);
      }
    }

Point to be noted;

The method you set/get should be public or protected(take care) but strictly shouldnt be private.

The strncpy() function is the safer one: you have to pass the maximum length the destination buffer can accept. Otherwise it could happen that the source string is not correctly 0 terminated, in which case the strcpy() function could write more characters to destination, corrupting anything which is in the memory after the destination buffer. This is the buffer-overrun problem used in many exploits

Also for POSIX API functions like read() which does not put the terminating 0 in the buffer, but returns the number of bytes read, you will either manually put the 0, or copy it using strncpy().

In your example code, index is actually not an index, but a count - it tells how many characters at most to copy from source to destination. If there is no null byte among the first n bytes of source, the string placed in destination will not be null terminated

PostgreSQL implementation would be:

DELETE FROM t1
USING t2
WHERE t1.id = t2.id;

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

You can do this

String stringUrl = "https://ipinfo.io/ip";
//String stringUrl = "http://whatismyip.akamai.com/";
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(MainActivity.instance);
//String url ="http://www.google.com";

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, stringUrl,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                // Display the first 500 characters of the response string.
                Log.e(MGLogTag, "GET IP : " + response);

            }
        }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        IP = "That didn't work!";
    }
});

// Add the request to the RequestQueue.
queue.add(stringRequest);

For Postgres

ALTER TABLE table_name ADD field_name serial PRIMARY KEY

REFERENCE: https://www.tutorialspoint.com/postgresql/postgresql_using_autoincrement.htm

If all else fails you can also use

"My text needs a line break here" + System.Environment.NewLine + " This should be a new line"

I've had success building iOS apps on linux using the iOS clang toolchain by cjacker. Basically it consists of the upstream clang and llvm tools from your linux distro, a linux port of apple's linker and some extra tools to help simplify the build process (such as converting xcode projects to Makefile format).

It does take a few steps to install, but you're a software developer so you'd be used to that. I posted an up to date howto for Debian 7 (Wheezy) online:

https://rogerkeays.com/how-to-build-an-ios-toolchain-for-linux-debian-7

Otherwise you want to go with the generic instructions which are a little older:

Good luck.

On demand, now as an answer...

When using MySQL Query Browser or phpMyAdmin, it appears that a new connection is opened for each query (bugs.mysql.com/bug.php?id=8280), making it neccessary to write all the drop statements in one query, eg.

SET FOREIGN_KEY_CHECKS=0; 
DROP TABLE my_first_table_to_drop; 
DROP TABLE my_second_table_to_drop; 
SET FOREIGN_KEY_CHECKS=1; 

Where the SET FOREIGN_KEY_CHECKS=1 serves as an extra security measure...

Right click on the table and click on Design,then click on column that you want to set default value.

Then in bottom of page in column properties set Default value or binding to : 'getdate()'

If table_2 is empty, then try the following insert statement:

insert into table_2 (itemid,location1) 
select itemid,quantity from table_1 where locationid=1

If table_2 already contains the itemid values, then try this update statement:

update table_2 set location1=
(select quantity from table_1 where locationid=1 and table_1.itemid = table_2.itemid)

You can use Cell.Interior.Color, I've used it to count the number of cells in a range that have a given background color (ie. matching my legend).

-DBL_MAX in ANSI C, which is defined in float.h.

My solution was:

1. Remove ${HOME}/m2/repository.
2. Click on IntelliJ => Invalidate Caches / Restart.
3. Refresh Maven Project.

Type on terminal:

chmod -Rf 700 ~/.ssh/

And try again.

Easily accomplished using a package.

Others have mentioned Moment. Moment is great but very large for a simple use like this, and unfortunately not modular so you have to import the whole package to use any of it.

I recommend using date-fns (https://date-fns.org/) (https://github.com/date-fns/date-fns). It is light-weight and modular, so you can import only the functions that you need.

In your case:

Install it: npm install date-fns --save

In your component:

import { format } from "date-fns";

var date = new Date("2016-01-04 10:34:23");

var formattedDate = format(date, "MMMM do, yyyy H:mma");

console.log(formattedDate);

Substitute the format string above "MMMM do, yyyy H:mma" with whatever format you require.

Update: v1 vs v2 format differences

v1 used Y for year and D for day, while v2 uses y and d. Format strings above have been updated for v2; the equivalent for v1 would be "MMMM Do, YYYY H:mma" (source: https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg/). Thanks @Red

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

After reading the posts using pyPDF2.

The error while using @sylvain's code NotImplementedError: unsupported filter /DCTDecode must come from the method .getData(): It is solved when using ._data instead, by @Alex Paramonov.

So far I have only met "DCTDecode" cases, but I am sharing the adapted code that include remarks from the different posts: From zilb by @Alex Paramonov, sub_obj['/Filter'] being a list, by @mxl.

yes, of course! in fact, writing if(pointer) is a more convenient way of writing rather than if(pointer != NULL) because: 1. it is easy to debug 2. easy to understand 3. if accidently, the value of NULL is defined, then also the code will not crash

If you want to clean up all your gems and start over

sudo gem clean

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

Hex -> decimal:

Convert.ToInt64(hexValue, 16);

Decimal -> Hex

string.format("{0:x}", decValue);

Syntax check

To check configuration files for syntax errors:

# Red Hat-based (Fedora, CentOS) and OSX
httpd -t

# Debian-based (Ubuntu)
apache2ctl -t

# MacOS
apachectl -t

List virtual hosts

To list all virtual hosts, and their locations:

# Red Hat-based (Fedora, CentOS) and OSX
httpd -S

# Debian-based (Ubuntu)
apache2ctl -S

# MacOS
apachectl -S

Yours: Lowest possible is min, highest possible is max+min-1

Google: Lowest possible is min, highest possible is max-1

Here is an example that lists all the files on my desktop. you should change the path variable to your path.

Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.

public static void main(String[] args) {
    File path = new File("c:/documents and settings/Zachary/desktop");

    File [] files = path.listFiles();
    for (int i = 0; i < files.length; i++){
        if (files[i].isFile()){ //this line weeds out other directories/folders
            System.out.println(files[i]);
        }
    }
}

You should be able to put them in your ~/matlab on unix.

I'm not sure which directory matlab looks in for windows, but you should be able to figure it out by executing userpath from the matlab command line.

You would have to first create your migration for the model basics then you create another migration to modify your previous using the change_column ...

def change
    change_column :widgets, :colour, :string, default: 'red'
end

This will insert a new element after the input field with id "password".

$(document).ready(function(){
  var newInput = $("<input name='new_field' type='text'>");
  $('input#password').after(newInput);
});

Not sure if this answers your question.

Steps as of Chrome v79 (2/24/2020):

1. Click the (i) button next to the URL

2. Click Site settings on the popup box

3. At the bottom of the list is "Insecure content", change this to Allow

4. Go back to the site and Refresh the page

Older Chrome Versions:

In the address bar at the right end should be a 'shield' icon, you can click on that to run insecure content.

This worked for me in Chromium-dev Version 36.0.1933.0 (262849).

Auto PY to EXE - A .py to .exe converter using a simple graphical interface built using Eel and PyInstaller in Python.

py2exe is probably what you want, but it only works on Windows.
PyInstaller works on Windows and Linux.
Py2app works on the Mac.

It works for me:

open(filename,'r')   #2nd argument is r and not w

will open the file or give an error if it doesn't exist. If there's an error, then you can try to write to the path, if you can't then you get a second error

def some_view(request):
    if request.method == 'POST':
        form = SomeForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
    else:
        form = SomeForm()
    return render(request, 'some_form.html', {'form': form})

Based on this answer by @ybendana:

Again, we use is_bound to check if the form is capable of validation. See this section of the documentation:

Bound and unbound forms

A Form instance is either bound to a set of data, or unbound.

• If it’s bound to a set of data, it’s capable of validating that data and rendering the form as HTML with the data displayed in the HTML.
• If it’s unbound, it cannot do validation (because there’s no data to validate!), but it can still render the blank form as HTML.

We use a list of tuples for form objects and their details allowing for more extensibility and less repetition.

However, instead of overriding get(), we override get_context_data() to make inserting a new, blank instance of the form (with prefix) into the response the default action for any request. In the context of a POST request, we override the post() method to:

1. Use the prefix to check if each form has been submitted
2. Validate the forms that have been submitted
3. Process the valid forms using the cleaned_data
4. Return any invalid forms to the response by overwriting the context data

# views.py

class MultipleForms(TemplateResponseMixin, ContextMixin, View):

    form_list = [ # (context_key, formcls, prefix)
        ("form_a", FormA, "prefix_a"),
        ("form_b", FormB, "prefix_b"),
        ("form_c", FormC, "prefix_c"),
        ...
        ("form_x", FormX, "prefix_x"),
    ]

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        # Add blank forms to context with prefixes
        for context_key, formcls, prefix in self.form_list:
            context[context_key] = formcls(prefix=prefix)
        return context

    def post(self, request, *args, **kwargs):
        # Get object and context
        self.object = self.get_object()
        context = self.get_context_data(object=self.object)
        # Process forms
        for context_key, formcls, prefix in self.form_list:
            if prefix in request.POST:
                # Get the form object with prefix and pass it the POST data to \
                # validate and clean etc.
                form = formcls(request.POST, prefix=prefix)
                if form.is_bound:
                    # If the form is bound (i.e. it is capable of validation)  \
                    # check the validation
                    if form.is_valid():
                        # call the form's save() method or do whatever you     \
                        # want with form.cleaned_data
                        form.save()
                    else:
                        # overwrite context data for this form so that it is   \
                        # returned to the page with validation errors
                        context[context_key] = form
        # Pass context back to render_to_response() including any invalid forms
        return self.render_to_response(context)
        

This method allows repeated form entries on the same page, something I found did not work with @ybendana's answer.

I believe it wouldn't be masses more work to fold this method into a Mixin class, taking the form_list object as an attribute and hooking get_context_data() and post() as above.

Edit: This already exists. See this repository.

NB: This method required TemplateResponseMixin for render_to_response() and ContextMixin for get_context_data() to work. Either use these Mixins or a CBV that descends from them.

It's simple

y = [['vegas','London'],['US','UK']]

for x in y:
    for a in x:
        print(a)

It is originally an answer in the comments from @Mark Rajcok, But I want to place it here as a tested and worked as a solution using ChangeDetectorRef , I see a good point here:

Another alternative is to inject ChangeDetectorRef and call cdRef.detectChanges() instead of zone.run(). This could be more efficient, since it will not run change detection over the entire component tree like zone.run() does. – Mark Rajcok

So code must be like:

import {Component, OnInit, ChangeDetectorRef} from 'angular2/core';

export class RecentDetectionComponent implements OnInit {

    recentDetections: Array<RecentDetection>;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        timer.subscribe(() => this.getRecentDetections());
    }
} 

Edit: Using .detectChanges() inside subscibe could lead to issue Attempt to use a destroyed view: detectChanges

To solve it you need to unsubscribe before you destroy the component, so the full code will be like:

import {Component, OnInit, ChangeDetectorRef, OnDestroy} from 'angular2/core';

export class RecentDetectionComponent implements OnInit, OnDestroy {

    recentDetections: Array<RecentDetection>;
    private timerObserver: Subscription;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        this.timerObserver = timer.subscribe(() => this.getRecentDetections());
    }

    ngOnDestroy() {
        this.timerObserver.unsubscribe();
    }

}

Even if you have unchecked the "Display intranet sites in Compatibility View" option, and have the X-UA-Compatible in your response headers, there is another reason why your browser might default to "Compatibility View" anyways - your Group Policy. Look at your console for the following message:

HTML1203: xxx.xxx has been configured to run in Compatibility View through Group Policy.

Where xxx.xxx is the domain for your site (i.e. test.com). If you see this then the group policy for your domain is set so that any site ending in test.com will automatically render in Compatibility mode regardless of doctype, headers, etc.

For more information, please see the following link (explains the html codes): http://msdn.microsoft.com/en-us/library/ie/hh180764(v=vs.85).aspx

In Ubuntu it looks like this :

 $ sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
 $ sudo pip install python-ldap

I have the same problem and I solved it and the explanation is as follow:

If the Seaborn package is not installed in anaconda, you will not be able to update it, namely, if in the Terminal we type: conda update seaborn

it will fail showing: "PackageNotFoundError: Package not found: 'seaborn' Package 'seaborn' is not installed in /Users/yifan/anaconda"

Thus we need to install seaborn in anaconda first by typing in Terminal: conda install -c https://conda.anaconda.org/anaconda seaborn

Then the seaborn will be fetched and installed in the environment of anaconda, namely in my case, /Users/yifan/anaconda

Once this installation is done, we will be able to import seaborn in python.

Side note, to check and list all discoverable environments where python is installed in anaconda, type in Terminal: conda info --envs

You can also use the latest keyword to install the most recent version available:

  "dependencies": {
    "fontawesome": "latest"
  }

JS:

$.ajax({
    url: "ajax.php",
    type: "POST",
    data: "width=" + $("body").width(),
    success: function(msg) {

        return true;
    }
});

ajax.php

if(!empty($_POST['width']))
    $width = (int)$_POST['width'];

Try this:

$('#foo1').html($('#foo2').children().clone());

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

In PostMan we have ->Pre-request Script. Paste the Below snippet.

const dateNow = new Date();
postman.setGlobalVariable("todayDate", dateNow.toLocaleDateString());

And now we are ready to use.

{
"firstName": "SANKAR",
"lastName": "B",
"email": "[email protected]",
"creationDate": "{{todayDate}}"
}

If you are using JPA Entity classes then use the below snippet

    @JsonFormat(pattern="MM/dd/yyyy")
    @Column(name = "creation_date")
    private Date creationDate;

enter image description here enter image description here

You are looking for:

var yourVar = '1324567890abc§$)%';
yourVar = yourVar.replace(/[^a-zA-Z0-9]/g, ' ');

This replaces all non-alphanumeric characters with a space.

The "g" on the end replaces all occurrences.

Instead of specifying a-z (lowercase) and A-Z (uppercase) you can also use the in-case-sensitive option: /[^a-z0-9]/gi.

Android Studio & Windows :

fn + alt + insert

There is a new Android api that allows the user to select their phonenumber without the need for a permission. Take a look at: https://android-developers.googleblog.com/2017/10/effective-phone-number-verification.html

// Construct a request for phone numbers and show the picker
private void requestHint() {
    HintRequest hintRequest = new HintRequest.Builder()
       .setPhoneNumberIdentifierSupported(true)
       .build();

    PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(
        apiClient, hintRequest);
    startIntentSenderForResult(intent.getIntentSender(),
        RESOLVE_HINT, null, 0, 0, 0);
} 

Sorry for resurrection. You could use child_process module to execute external js files in node.js

var child_process = require('child_process');

//EXECUTE yourExternalJsFile.js
child_process.exec('node yourExternalJsFile.js', (error, stdout, stderr) => {
    console.log(`${stdout}`);
    console.log(`${stderr}`);
    if (error !== null) {
        console.log(`exec error: ${error}`);
    }
});

The browser will only detect your username if the IIS server is on the same domain and the security settings within your group policy allow it.

Otherwise you will have to provide it with credentials, but if it is not on the same domain, it will not be able to authenticate you.

You may try (if MySQL):

SELECT salary FROM employee ORDER BY salary DESC LIMIT 2, 1;

This query returns one row after skipping two rows.

You may also want to return distinct salary. For example, if you have 20,20,10 and 5 then 5 is the third highest salary. To do so, add DISTINCT to the above query:

SELECT DISTINCT salary FROM employee ORDER BY salary DESC LIMIT 2, 1;

One can issue the SQL*Plus command SET TIMING ON to get wall-clock times, but one can't take, for example, fetch time out of that trivially.

The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it.

Lastly, one can trace the SQL*Plus session, and manually calculate the time spent waiting on events which are client waits, such as "SQL*Net message to client", "SQL*Net message from client".

Lombok does not support that also indicated by making any @Value annotated class final (as you know by using @NonFinal).

The only workaround I found is to declare all members final yourself and use the @Data annotation instead. Those subclasses need to be annotated by @EqualsAndHashCode and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:

@Data
public class A {
    private final int x;
    private final int y;
}

@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
    private final int z;

    public B(int x, int y, int z) {
        super(x, y);
        this.z = z;
    }
}

Especially the constructors of the subclasses make the solution a little untidy for superclasses with many members, sorry.

if we know the table and colum names but want to find out the number of times string is appearing for each schema:

reason varchar2(1000);
x varchar2(1000):='%string_to_be_searched%';

cursor csr is select owner,table_name 
from all_tables where table_name ='table_name';

type rec1 is record (
ct VARCHAR2(1000));

type rec is record (
owner VARCHAR2(1000):='',
table_name VARCHAR2(1000):='');

rec2 rec;
rec3 rec1;
begin

for rec2 in csr loop

--str_sql:= 'select count(*) from '||rec.owner||'.'||rec.table_name||' where CTV_REMARKS like '||chr(39)||x||chr(39);
--dbms_output.put_line(str_sql);
--execute immediate str_sql

execute immediate 'select count(*) from '||rec2.owner||'.'||rec2.table_name||' where column_name like '||chr(39)||x||chr(39)
into rec3;
if rec3.ct <> 0 then
dbms_output.put_line(rec2.owner||','||rec3.ct);

Python

df = spark.read
    .option("header", "true")
    .format("csv")
    .schema(myManualSchema)
    .load("mycsv.csv")

Scala

val myDf = spark.read
  .option("header", "true")
  .format("csv")
  .schema(myManualSchema)
  .load("mycsv.csv")

PD1: myManualSchema is a predefined schema written by me, you could skip that part of code

UPDATE 2021 The same code works for Spark 3.x

df = spark.read
    .option("header", "true")
    .option("inferSchema", "true")
    .format("csv")
    .csv("mycsv.csv")

It means you're trying to call something that isn't a function

const foo = 'string'
foo() // error

I noticed this question a couple of days late, but I feel that I can add some insight. I hope this can be helpful towards your RESTful venture.

Point 1: Am I understanding it right?

You understood right. That is a correct representation of a RESTful architecture. You may find the following matrix from Wikipedia very helpful in defining your nouns and verbs:

When dealing with a Collection URI like: http://example.com/resources/

• GET: List the members of the collection, complete with their member URIs for further navigation. For example, list all the cars for sale.

• PUT: Meaning defined as "replace the entire collection with another collection".

• POST: Create a new entry in the collection where the ID is assigned automatically by the collection. The ID created is usually included as part of the data returned by this operation.

• DELETE: Meaning defined as "delete the entire collection".

When dealing with a Member URI like: http://example.com/resources/7HOU57Y

• GET: Retrieve a representation of the addressed member of the collection expressed in an appropriate MIME type.

• PUT: Update the addressed member of the collection or create it with the specified ID.

• POST: Treats the addressed member as a collection in its own right and creates a new subordinate of it.

• DELETE: Delete the addressed member of the collection.

Point 2: I need more verbs

In general, when you think you need more verbs, it may actually mean that your resources need to be re-identified. Remember that in REST you are always acting on a resource, or on a collection of resources. What you choose as the resource is quite important for your API definition.

Activate/Deactivate Login: If you are creating a new session, then you may want to consider "the session" as the resource. To create a new session, use POST to http://example.com/sessions/ with the credentials in the body. To expire it use PUT or a DELETE (maybe depending on whether you intend to keep a session history) to http://example.com/sessions/SESSION_ID.

Change Password: This time the resource is "the user". You would need a PUT to http://example.com/users/USER_ID with the old and new passwords in the body. You are acting on "the user" resource, and a change password is simply an update request. It's quite similar to the UPDATE statement in a relational database.

My instinct would be to do a GET call to a URL like /api/users/1/activate_login

This goes against a very core REST principle: The correct usage of HTTP verbs. Any GET request should never leave any side effect.

For example, a GET request should never create a session on the database, return a cookie with a new Session ID, or leave any residue on the server. The GET verb is like the SELECT statement in a database engine. Remember that the response to any request with the GET verb should be cache-able when requested with the same parameters, just like when you request a static web page.

Point 3: How to return error messages and codes

Consider the 4xx or 5xx HTTP status codes as error categories. You can elaborate the error in the body.

Failed to Connect to Database: / Incorrect Database Login: In general you should use a 500 error for these types of errors. This is a server-side error. The client did nothing wrong. 500 errors are normally considered "retryable". i.e. the client can retry the same exact request, and expect it to succeed once the server's troubles are resolved. Specify the details in the body, so that the client will be able to provide some context to us humans.

The other category of errors would be the 4xx family, which in general indicate that the client did something wrong. In particular, this category of errors normally indicate to the client that there is no need to retry the request as it is, because it will continue to fail permanently. i.e. the client needs to change something before retrying this request. For example, "Resource not found" (HTTP 404) or "Malformed Request" (HTTP 400) errors would fall in this category.

Point 4: How to do authentication

As pointed out in point 1, instead of authenticating a user, you may want to think about creating a session. You will be returned a new "Session ID", along with the appropriate HTTP status code (200: Access Granted or 403: Access Denied).

You will then be asking your RESTful server: "Can you GET me the resource for this Session ID?".

There is no authenticated mode - REST is stateless: You create a session, you ask the server to give you resources using this Session ID as a parameter, and on logout you drop or expire the session.

That worked for me:

sudo -u postgres psql db_name < 'file_path'

I'm surprised no one has suggested one of the most obvious ways to go:

public class TimeDependentClass
{
    public void TimeDependentMethod(DateTime someTime)
    {
        if (GetCurrentTime() > someTime) DoSomething();
    }

    protected virtual DateTime GetCurrentTime()
    {
        return DateTime.Now; // or UtcNow
    }
}

Then you can simply override this method in your test double.

I also kind of like injecting a TimeProvider class in some cases, but for others, this is more than enough. I'd probably favor the TimeProvider version if you need to reuse this in several classes though.

EDIT: For anyone interested, this is called adding a "seam" to your class, a point where you can hook in to it's behavior to modify it (for testing purposes or otherwise) without actually having to change the code in the class.

To the best of my memory, a physical address is an explicit, set in stone address in memory, while a logical address consists of a base pointer and offset.

The reason is as you have basically specified. It allows for not only the segmentation of programs and processes into threads and data, but also for the dynamic loading of such programs, and the allowance for at least pseudo-parallelism, without any actual interlacing of instructions in memory needing to take place.

I had just this problem and I found a similar answer here.

The method is to set top the way you want it and then press W (capital W). This saves top's current layout to a configuration file in $HOME/.toprc

Although this might not work if you want to run multiple top's with different configurations.

So via what I consider a work around you can write to different config files / use different config files by doing one of the following...

1) Rename the binary

  ln -s /usr/bin/top top2
  ./top2

Now .top2rc is going to be written to your $HOME

2) Set $HOME to some alternative path, since it will write its config file to the $HOME/.binary-name.rc file

HOME=./
top

Now .toprc is going to be written to the current folder.

Via use of other peoples comments to add the various usage accounting in top you can create a batch output for that information and latter coalesces the information via a script. Maybe not quite as simple as you script but I found top to provide me ALL processes so that later I can recap and capture a state during a long run that I might have missed otherwise (unexplained sudden CPU usage due to stray processes)

The problem I had was because I had made a database in my LocalDb.
If that's the case then you have to write is as shown below:

    "SELECT * FROM <DatabaseName>.[dbo].[Projects]"

Replace with your database name.
You can probably also drop the "[ ]"

You can try this, $myArray as the Array

$filename = "mylog.txt";
$text = "";
foreach($myArray as $key => $value)
{
    $text .= $key." : ".$value."\n";
}
$fh = fopen($filename, "w") or die("Could not open log file.");
fwrite($fh, $text) or die("Could not write file!");
fclose($fh);

Yep, why not?

fs.Write(myByteArray, 0, myByteArray.Length);

Just incase anyone else stumbles across this, I use the fs-extra library in node and write javascript objects to a file like this:

const fse = require('fs-extra');
fse.outputJsonSync('path/to/output/file.json', objectToWriteToFile); 

No, you can't get it quite like background-size:cover but..

This approach is pretty damn close: it uses JavaScript to determine if the image is landscape or portrait, and applies styles accordingly.

JS

 $('.myImages img').load(function(){
        var height = $(this).height();
        var width = $(this).width();
        console.log('widthandheight:',width,height);
        if(width>height){
            $(this).addClass('wide-img');
        }else{
            $(this).addClass('tall-img');
        }
    });

CSS

.tall-img{
    margin-top:-50%;
    width:100%;
}
.wide-img{
    margin-left:-50%;
    height:100%;
}

For a custom class to work properly in collections you'll have to implement/override the equals() methods of the class. For sorting also override compareTo().

See this article or google about how to implement those methods properly.

first find your binaries file where it is saved. get the path in terminal mine is

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin

then find your local user data path, it is in mostly

C:\usr\local\pgsql\data

now all we have to hit following command in the binary terminal path:

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin>pg_ctl -D "C:\usr\local\pgsql\data" start

all done!

autovaccum launcher started! cheers!

Put in all your svg:

fill="var(--svgcolor)"

In Css:

:root {
  --svgcolor: tomato;
}

To use pseudo-classes:

span.github:hover {
  --svgcolor:aquamarine;
}

Explanation

root = html page.
--svgcolor = a variable.
span.github = selecting a span element with a class github, a svg icon inside and assigning pseudo-class hover.

You can use jQuery to clear the value of your date input.

For exemple with a button and a text input like this :

<input type="text" id="datepicker">
<button id="reset-date">Reset</button>

You can use the .val() function of jQuery.

$("#reset-date").click(function(){
    $('#datepicker').val("").datepicker("update");
})

Note:

$('#my_table > tbody:last').append(newRow); // this will add new row inside tbody

$("table#myTable tr").last().after(newRow);  // this will add new row outside tbody 
                                             //i.e. between thead and tbody
                                             //.before() will also work similar

ES6 solution:

const timestamp = () => `[${new Date().toUTCString()}]`
const log = (...args) => console.log(timestamp(), ...args)

where timestamp() returns actually formatted timestamp and log add a timestamp and propagates all own arguments to console.log

Make sure the .gitignore does not have a extension!! It can't be .gitignore.txt, in windows just name the file .gitignore. and it will work.

It's a simple Mistake while adding a new file you just have to make sure that \ is added to the file before and the new file remain as it is eg.

In Java 8 we can use stream List1.stream().collect(Collectors.toList()).addAll(List2); Another option List1.addAll(List2)

Here's a cross browser working function (usable for other than click handlers too):

function eventFire(el, etype){
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      var evObj = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
}

The simplest solution might be to install Java 8 in parallel to Java 9 (if not still still existant) and specify the JVM to be used explicitly in eclipse.ini. You can find a description of this setting including a description how to find eclipse.ini on a Mac at Eclipsepedia

This can be a huge approximation depending on your polygons, but here's one :

• Compute the center of mass for each polygon.
• Compute the min or max or average distance from each point of the polygon to the center of mass.
• If C1C2 (where C1/2 is the center of the first/second polygon) >= D1 + D2 (where D1/2 is the distance you computed for first/second polygon) then the two polygons "intersect".

Though, this should be very efficient as any transformation to the polygon applies in the very same way to the center of mass and the center-node distances can be computed only once.

Related, so I thought I would post for others. If you want to find the UTC of the start of today (for your timezone) the following code works for any UTC offset (-23.5 thru +23.5). This looks like we add X hours then subtract X hours, but the important thing is the ".Date" after the add.

double utcOffset= 10.0;  // Set to your UTC offset in hours (eg. Melbourne Australia)
var now = DateTime.UtcNow;

var startOfToday = now.AddHours(utcOffset - 24.0).Date;
startOfToday = startOfToday.AddHours(24.0 - utcOffset);

There is nothing like kafka --version at this point. So you should either check the version from your kafka/libs/ folder or you can run

find ./libs/ -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*'

from your kafka folder (and it will do the same for you). It will return you something like kafka_2.9.2-0.8.1.1.jar.asc where 0.8.1.1 is your kafka version.

Probably the only choice is to read it on the client side and transfer it manually to the server (GET/POST/AJAX). Regards Artur

If each item in the list is a string (and any strings inside those strings use " " rather than ' '), you can use regular expressions (re module)

>>> flattener = re.compile("\'.*?\'")
>>> flattener
<_sre.SRE_Pattern object at 0x10d439ca8>
>>> stred = str(in_list)
>>> outed = flattener.findall(stred)

The above code converts in_list into a string, uses the regex to find all the substrings within quotes (i.e. each item of the list) and spits them out as a list.

    let messageLabel    =   UILabel()

    let loadingSV       =   UIStackView()
    let loadingView     =   UIView()
    let activityIndicator: UIActivityIndicatorView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.gray)

    init(uiView: UIView, message: String) {

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

How about something like this...

Dim rs As RecordSet
Set rs = Currentdb.OpenRecordSet("SELECT PictureLocation, ID FROM MyAccessTable;")

Do While Not rs.EOF
   Debug.Print rs("PictureLocation") & " - " & rs("ID")
   rs.MoveNext
Loop

There are many ways in JavaScript to convert a string to a number value... All simple and handy, choose the way which one works for you:

var num = Number("999.5"); //999.5
var num = parseInt("999.5", 10); //999
var num = parseFloat("999.5"); //999.5
var num = +"999.5"; //999.5

Also any Math operation converts them to number, for example...

var num = "999.5" / 1; //999.5
var num = "999.5" * 1; //999.5
var num = "999.5" - 1 + 1; //999.5
var num = "999.5" - 0; //999.5
var num = Math.floor("999.5"); //999
var num = ~~"999.5"; //999

My prefer way is using + sign, which is the elegant way to convert a string to number in JavaScript.

Use an <intent-filter> with a <data> element. For example, to handle all links to twitter.com, you'd put this inside your <activity> in your AndroidManifest.xml:

<intent-filter>
    <data android:scheme="http" android:host="twitter.com"/>
    <action android:name="android.intent.action.VIEW" />
</intent-filter>

Then, when the user clicks on a link to twitter in the browser, they will be asked what application to use in order to complete the action: the browser or your application.

Of course, if you want to provide tight integration between your website and your app, you can define your own scheme:

<intent-filter>
    <data android:scheme="my.special.scheme" />
    <action android:name="android.intent.action.VIEW" />
</intent-filter>

Then, in your web app you can put links like:

<a href="my.special.scheme://other/parameters/here">

And when the user clicks it, your app will be launched automatically (because it will probably be the only one that can handle my.special.scheme:// type of uris). The only downside to this is that if the user doesn't have the app installed, they'll get a nasty error. And I'm not sure there's any way to check.

Edit: To answer your question, you can use getIntent().getData() which returns a Uri object. You can then use Uri.* methods to extract the data you need. For example, let's say the user clicked on a link to http://twitter.com/status/1234:

Uri data = getIntent().getData();
String scheme = data.getScheme(); // "http"
String host = data.getHost(); // "twitter.com"
List<String> params = data.getPathSegments();
String first = params.get(0); // "status"
String second = params.get(1); // "1234"

You can do the above anywhere in your Activity, but you're probably going to want to do it in onCreate(). You can also use params.size() to get the number of path segments in the Uri. Look to javadoc or the android developer website for other Uri methods you can use to extract specific parts.

You could use the Any() extension method. The following seems to work for me.

XStreamingElement root = new XStreamingElement("Results",
                from el in StreamProductItem(file)
                where fieldsToSearch.Any(s => el.Element(s) != null && el.Element(s).Value.Contains(searchTerm))
                select fieldsToReturn.Select(r => (r == "product") ? el : el.Element(r))
            );
            Console.WriteLine(root.ToString());

Where 'fieldsToSearch' and 'fieldsToReturn' are both List objects.

Private Function LoaderData(ByVal strSql As String) As DataTable
    Dim cnn As SqlConnection
    Dim dad As SqlDataAdapter

    Dim dtb As New DataTable
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        dad = New SqlDataAdapter(strSql, cnn)
        dad.Fill(dtb)
        cnn.Close()
        dad.Dispose()
    Catch ex As Exception
        cnn.Close()
        MsgBox(ex.Message)
    End Try
    Return dtb
End Function

This will check for empty textarea as well as will not allow only Spaces in textarea coz that looks empty too.

 var txt_msg = $("textarea").val();

 if (txt_msg.replace(/^\s+|\s+$/g, "").length == 0 || txt_msg=="") {
    return false;
  }

This is how I have achieved it using purely CSS and HTML (no JavaScript/images etc.).

It gracefully degrades in most browsers (I do need to add in a fix for lack of last-of-type in < IE9).

you can use android:focusable="false" but also need to disable cursor otherwise copy/paste function would still work.

so, use

android:focusable="false"
android:cursorVisible="false"

It's really just a coding style. The compiler generates the exact same for both variants.

See also here for the performance question:

• Will using 'var' affect performance?

Below is a 2-way extension class that supports:

• Timezone localization
• Input\output in seconds or milliseconds.

In OP's case, usage is:

DateTime.Now.ToUnixtime();

or

DateTime.UtcNow.ToUnixtime();

Even though a direct answer exists, I believe using a generic approach is better. Especially because it's most likely a project that needs a conversion like this, will also need these extensions anyway, so it's better to use the same tool for all.

    public static class UnixtimeExtensions
    {
        public static readonly DateTime UNIXTIME_ZERO_POINT = new DateTime(1970, 1, 1, 0, 0,0, DateTimeKind.Utc);

        /// <summary>
        /// Converts a Unix timestamp (UTC timezone by definition) into a DateTime object
        /// </summary>
        /// <param name="value">An input of Unix timestamp in seconds or milliseconds format</param>
        /// <param name="localize">should output be localized or remain in UTC timezone?</param>
        /// <param name="isInMilliseconds">Is input in milliseconds or seconds?</param>
        /// <returns></returns>
        public static DateTime FromUnixtime(this long value, bool localize = false, bool isInMilliseconds = true)
        {
            DateTime result;

            if (isInMilliseconds)
            {
                result = UNIXTIME_ZERO_POINT.AddMilliseconds(value);
            }
            else
            {
                result = UNIXTIME_ZERO_POINT.AddSeconds(value);
            }

            if (localize)
                return result.ToLocalTime();
            else
                return result;
        }

        /// <summary>
        /// Converts a DateTime object into a Unix time stamp
        /// </summary>
        /// <param name="value">any DateTime object as input</param>
        /// <param name="isInMilliseconds">Should output be in milliseconds or seconds?</param>
        /// <returns></returns>
        public static long ToUnixtime(this DateTime value, bool isInMilliseconds = true)
        {
            if (isInMilliseconds)
            {
                return (long)value.ToUniversalTime().Subtract(UNIXTIME_ZERO_POINT).TotalMilliseconds;
            }
            else
            {
                return (long)value.ToUniversalTime().Subtract(UNIXTIME_ZERO_POINT).TotalSeconds;
            }
        }
    }

I don't think you could change the style of browsers' default alert boxes.

You need to create your own or use a simple and customizable library like xdialog. Following is a example to customize the alert box. More demos can be found here.

function show_alert() {_x000D_
    xdialog.alert("Hello! I am an alert box!");_x000D_
}

<head>_x000D_
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/xxjapp/xdialog@3/xdialog.min.css"/>_x000D_
    <script src="https://cdn.jsdelivr.net/gh/xxjapp/xdialog@3/xdialog.min.js"></script>_x000D_
    _x000D_
    <style>_x000D_
        .xd-content .xd-body .xd-body-inner {_x000D_
            max-height: unset;_x000D_
        }_x000D_
        .xd-content .xd-body p {_x000D_

        }_x000D_
        .xd-content .xd-button.xd-ok {_x000D_
            background: #734caf;_x000D_
        }_x000D_

Not escaping double quotes is the cause of OP's problem. A readable approach to escape double quotes is using backticks (MDN). Here is a sample solution:

my_btn.setAttribute('onclick', `my_func("${onclick_var1}", "${onclick_var2}")`);

Whenever you are working with csv imports, try to use df.dropna() to avoid all such warnings or errors.

The Hacker's Delight bit-twiddling becomes so much clearer when you write out the bit patterns.

unsigned int bitCount(unsigned int x)
{
  x = ((x >> 1) & 0b01010101010101010101010101010101)
     + (x       & 0b01010101010101010101010101010101);
  x = ((x >> 2) & 0b00110011001100110011001100110011)
     + (x       & 0b00110011001100110011001100110011); 
  x = ((x >> 4) & 0b00001111000011110000111100001111)
     + (x       & 0b00001111000011110000111100001111); 
  x = ((x >> 8) & 0b00000000111111110000000011111111)
     + (x       & 0b00000000111111110000000011111111); 
  x = ((x >> 16)& 0b00000000000000001111111111111111)
     + (x       & 0b00000000000000001111111111111111); 
  return x;
}

The first step adds the even bits to the odd bits, producing a sum of bits in each two. The other steps add high-order chunks to low-order chunks, doubling the chunk size all the way up, until we have the final count taking up the entire int.

What worked for me: I finally noticed the Build Executor Status window on the left on the main Jenkins dashboard. I run a dev/test instance on my local system with 2 executors. Both were currently occupied with builds that were not running. Upon cancelling these to jobs, my third (pending) job was able to run.

\n didn't work for me. the \n appear in the bodytext of the email I was sending.. this is how I resolved it.

str_pad($input, 990); //so that the spaces will pad out to the 990 cut off.

Swift 4 Update

I also tried many options still i wasn't able to get my UIButton round cornered. I added the corner radius code inside the viewDidLayoutSubviews() Solved My issue.

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = anyButton.frame.height / 2
    }

Also we can adjust the cornerRadius as follows

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = 10 //Any suitable number as you prefer can be applied 
    }

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

If you'd like to use printf(), you might want to also:

#include <stdio.h>

If you want to initialize an object based on an interface you can initialize it empty with following statement.

myObj: IMyObject = {} as IMyObject;

Here is some Perl code that tries to work around the limit by creating an inline view and then selecting from it. The statement text is compressed by using rows of twelve items each instead of selecting each item from DUAL individually, then uncompressed by unioning together all columns. UNION or UNION ALL in decompression should make no difference here as it all goes inside an IN which will impose uniqueness before joining against it anyway, but in the compression, UNION ALL is used to prevent a lot of unnecessary comparing. As the data I'm filtering on are all whole numbers, quoting is not an issue.

#
# generate the innards of an IN expression with more than a thousand items
#
use English '-no_match_vars';
sub big_IN_list{
    @_ < 13 and return join ', ',@_;
    my $padding_required = (12 - (@_ % 12)) % 12;  
    # get first dozen and make length of @_ an even multiple of 12
    my ($a,$b,$c,$d,$e,$f,$g,$h,$i,$j,$k,$l) = splice @_,0,12, ( ('NULL') x $padding_required );

    my @dozens; 
    local $LIST_SEPARATOR = ', '; # how to join elements within each dozen
    while(@_){
        push @dozens, "SELECT @{[ splice @_,0,12 ]} FROM DUAL"
    };  
    $LIST_SEPARATOR = "\n    union all\n    "; # how to join @dozens 
    return <<"EXP";
WITH t AS (
    select $a A, $b B, $c C, $d D, $e E, $f F, $g G, $h H, $i I, $j J, $k K, $l L FROM     DUAL
    union all
    @dozens
 )
select A from t union select B from t union select C from t union
select D from t union select E from t union select F from t union
select G from t union select H from t union select I from t union 
select J from t union select K from t union select L from t
EXP
}

One would use that like so:

my $bases_list_expr = big_IN_list(list_your_bases());
$dbh->do(<<"UPDATE");
    update bases_table set belong_to = 'us'
    where id in ($bases_list_expr)
UPDATE

Polling like this is definitely the least preferred solution.

I assume that you have another thread that will do something to make the condition true. There are several ways to synchronize threads. The easiest one in your case would be a notification via an Object:

Main thread:

synchronized(syncObject) {
    try {
        // Calling wait() will block this thread until another thread
        // calls notify() on the object.
        syncObject.wait();
    } catch (InterruptedException e) {
        // Happens if someone interrupts your thread.
    }
}

Other thread:

// Do something
// If the condition is true, do the following:
synchronized(syncObject) {
    syncObject.notify();
}

syncObject itself can be a simple Object.

There are many other ways of inter-thread communication, but which one to use depends on what precisely you're doing.

First, the valid syntax is

jQuery("input[name=ticketID]")

second, have you tried:

jQuery(":radio")

instead?

third, why not assign a class to all the radio buttons, and select them by class?

WHERE clause introduces a condition on individual rows; HAVING clause introduces a condition on aggregations, i.e. results of selection where a single result, such as count, average, min, max, or sum, has been produced from multiple rows. Your query calls for a second kind of condition (i.e. a condition on an aggregation) hence HAVING works correctly.

As a rule of thumb, use WHERE before GROUP BY and HAVING after GROUP BY. It is a rather primitive rule, but it is useful in more than 90% of the cases.

While you're at it, you may want to re-write your query using ANSI version of the join:

SELECT  L.LectID, Fname, Lname
FROM Lecturers L
JOIN Lecturers_Specialization S ON L.LectID=S.LectID
GROUP BY L.LectID, Fname, Lname
HAVING COUNT(S.Expertise)>=ALL
(SELECT COUNT(Expertise) FROM Lecturers_Specialization GROUP BY LectID)

This would eliminate WHERE that was used as a theta join condition.

In tensorflow you create graphs and pass values to that graph. Graph does all the hardwork and generate the output based on the configuration that you have made in the graph. Now When you pass values to the graph then first you need to create a tensorflow session.

tf.Session()

Once session is initialized then you are supposed to use that session because all the variables and settings are now part of the session. So, there are two ways to pass external values to the graph so that graph accepts them. One is to call the .run() while you are using the session being executed.

Other way which is basically a shortcut to this is to use .eval(). I said shortcut because the full form of .eval() is

tf.get_default_session().run(values)

You can check that yourself. At the place of values.eval() run tf.get_default_session().run(values). You must get the same behavior.

what eval is doing is using the default session and then executing run().

Given the specific title of this post, here's my suggestion:

ls | grep ' ' | tr ' ' '<' | sed 's|<|\\ |g'

The idea is to convert blanks to any unique character, like '<', and then change that into '\ ', a backslash followed by a blank. You can then pipe that into any command you like, such as:

ls | grep ' ' | tr ' ' '<' | sed 's|<|\\ |g' | xargs -L1 GetFileInfo

The key here lies in the 'tr' and 'sed' commands; and you can use any character besides '<', such as '?' or even a tab-character.

If you want to replace a simple string and you don't need the abilities of regular expressions, you can just use replace, not replaceAll.

replace replaces each matching substring but does not interpret its argument as a regular expression.

str = xpath.replace(".", "/*/");

The ternary operator is a way of writing conditional statements in Python. As the name ternary suggests, this Python operator consists of three operands.

Syntax: The three operands in a ternary operator include:

condition: A boolean expression that evaluates to either true or false.

true_val: A value to be assigned if the expression is evaluated to true.

false_val: A value to be assigned if the expression is evaluated to false.

    var = true_val if condition else false_val

The variable var on the left-hand side of the = (assignment) operator will be assigned:

value1 if the booleanExpression evaluates to true.

value2 if the booleanExpression evaluates to false.

Example:

    # USING TERNARY OPERATOR
    to_check = 6
    msg = "Even" if to_check%2 == 0 else "Odd"
    print(msg) 

    # USING USUAL IF-ELSE
    msg = ""
    if(to_check%2 == 0):
    msg = "Even"
    else:
    msg = "Odd"
    print(msg)

i did with

"start": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' --exec ts-node src/index.ts"

and yarn start.. ts-node not like 'ts-node'

Simple Pass Intent first

Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);

And u will get picture path on u onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            ImageView imageView = (ImageView) findViewById(R.id.imgView);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
        }
    }

Final Solution for this problem is below :

1. First make changes in applicationHost config file. replace below string setProfileEnvironment="false" TO setProfileEnvironment="true"

2. In your database connection string add below attribute : Integrated Security = SSPI

If someone is in search for a quick minimal solution,

import signal

# The code which crashes program on interruption

signal.signal(signal.SIGINT, call_this_function_if_interrupted)

# The code skipped if interrupted

they are similar but not same

set.seed(0)
x<-matrix(rnorm(10),1)

# one can compute from the other
rank(x)  == col(x)%*%diag(length(x))[order(x),]
order(x) == col(x)%*%diag(length(x))[rank(x),]
# rank can be used to sort
sort(x) == x%*%diag(length(x))[rank(x),]

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

User:  anonymous
Password:  [email protected]

+ means "one or more characters" and without the plus it means "one character." In your case both result in the same output.

I was also facing this issue even I was not using push notifications at all in my app.Making new provisioning profile also did not work for me.What I did was:-

1.Create fresh new certificate for Ad hoc & App Store only.

2.Then make distribution profile with this certificate and integrate profile with Xcode.

Then newly submitted build with this profile approved without any warning.

You simply need to use simpleCart

It is a free and open-source javascript shopping cart that easily integrates with your current website.

@TylerH has a great response but its a pretty complex solution. I have a solution for those of you that just want a simple "onclick" effect with pure css without a bunch of extra elements.

We will simply use css transitions. You could probably do similar with animations.

The trick is to change the delay for the transition so that it will last when the user clicks.

.arrowDownContainer:active,
.arrowDownContainer.clicked {
  filter: drop-shadow(0px 0px 0px steelblue);
  transition: filter 0s;
}

Here I add the "clicked" class as well so that javascript can also provide the effect if it needs to. I use 0px drop-shadow filter because it will highlight the given transparent graphic blue this way for my case.

I have a filter at 0s here so that it wont take effect. When the effect is released I can then add the transition with a delay so that it will provide a nice "clicked" effect.

.arrowDownContainer {
  cursor: pointer;
  position: absolute;
  bottom: 0px;
  top: 490px;
  left: 108px;
  height: 222px;
  width: 495px;
  z-index: 3;
  transition: filter 0.3s ease 0.3s;
}

This allows me to set it up so that when the user clicks the button, it highlights blue then fades out slowly (you could, of course, use other effects as well).

While you are limited here in the sense that the animation to highlight is instant, it does still provide the desired effect. You could likely use this trick with animation to produce a smoother overall transition.

I prefer this solution (based on the answer if @GK100):

1. I created a XIB and a class named SomeView (used the same name for convenience and readability). I based both on a UIView.
2. In the XIB, I changed the "File's Owner" class to SomeView (in the identity inspector).
3. I created a UIView outlet in SomeView.swift, linking it to the top level view in the XIB file (named it "view" for convenience). I then added other outlets to other controls in the XIB file as needed.

4. In SomeView.swift, I loaded the XIB inside the init or init:frame: CGRect initializer. There is no need to assign anything to "self". As soon as the XIB is loaded, all outlets are connected, including the top level view. The only thing missing, is to add the top view to the view hierarchy:

   class SomeView: UIView {
     override init(frame: CGRect) {
       super.init(frame: frame)
       NSBundle.mainBundle().loadNibNamed("SomeObject", owner: self, options: nil)
       self.addSubview(self.view);    // adding the top level view to the view hierarchy
     }
   
     required init(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
       NSBundle.mainBundle().loadNibNamed("SomeObject", owner: self, options: nil)
       self.addSubview(self.view);    // adding the top level view to the view hierarchy
     }
   
   
     ...
   }
   

DataSet myDataset = new DataSet();

DataTable customers = myDataset.Tables.Add("Customers");

customers.Columns.Add("Name");
customers.Columns.Add("Age");

customers.Rows.Add("Chris", "25");

//Get data
DataTable myCustomers = myDataset.Tables["Customers"];
DataRow currentRow = null;
for (int i = 0; i < myCustomers.Rows.Count; i++)
{
    currentRow = myCustomers.Rows[i];
    listBox1.Items.Add(string.Format("{0} is {1} YEARS OLD", currentRow["Name"], currentRow["Age"]));    
}

You can create a non-nullable DATETIME column on your table, and create a DEFAULT constraint on it to auto populate when a row is added.

e.g.

CREATE TABLE Example
(
SomeField INTEGER,
DateCreated DATETIME NOT NULL DEFAULT(GETDATE())
)

I based my answer on the title of your post only, as I don't know C# and didn't understand the given query. But in MySQL I suggest you try subselects. First get a set of primary keys of interesting columns then select data from those rows:

SELECT somecolumn, anothercolumn 
  FROM sometable 
 WHERE id IN (
               SELECT min(id) 
                 FROM sometable 
                GROUP BY somecolumn
             );

MySQL 5.7 supports computed columns. They call it "Generated Columns" and the syntax is a little weird, but it supports the same options I see in other databases.

https://dev.mysql.com/doc/refman/5.7/en/create-table.html#create-table-generated-columns

If you are using shared hosting, then there are chances that outbound port might be disabled by your hosting provider. So please contact your hosting provider and they will open the outbound port for you

Correct the ORACLE_HOME path.

There could be two oracle clients in the system.

I had the same issue, the reason being my ORACLE_HOME was pointed to the oracle installation which was not having the tns.ora file.

Changing the ORACLE_HOME to the Oracle directory which is having the tns.ora solved it.

tns.ora lies in client2\network\admin\

To make the answer more re-usable for things other than just the datepicker change function you can create a prototype to handle this for you.

// safety check to see if the prototype name is already defined
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};
Date.method('inPast', function () {
    return this < new Date($.now());// the $.now() requires jQuery
});

// including this prototype as using in example
Date.method('addDays', function (days) {
    var date = new Date(this);
    date.setDate(date.getDate() + (days));    
    return date;
});

If you dont like the safety check you can use the conventional way to define prototypes:

Date.prototype.inPast = function(){
    return this < new Date($.now());// the $.now() requires jQuery
}

Example Usage

var dt = new Date($.now());
var yesterday = dt.addDays(-1);
var tomorrow = dt.addDays(1);
console.log('Yesterday: ' + yesterday.inPast());
console.log('Tomorrow: ' + tomorrow.inPast());

$('#frm input[type="radio":checked]').each(function(){
   $(this).checked = false;  
  });

This is almost good but you missed the [0]

Correct ->> $(this)[0].checked = false;

I sorted this problem by verifying the json on JSONLint.com and then using Jackson. Below is the code for the same.

 Main Class:-

String jsonStr = "[{\r\n" + "       \"name\": \"John\",\r\n" + "        \"city\": \"Berlin\",\r\n"
                + "         \"cars\": [\r\n" + "            \"FIAT\",\r\n" + "          \"Toyata\"\r\n"
                + "     ],\r\n" + "     \"job\": \"Teacher\"\r\n" + "   },\r\n" + " {\r\n"
                + "     \"name\": \"Mark\",\r\n" + "        \"city\": \"Oslo\",\r\n" + "        \"cars\": [\r\n"
                + "         \"VW\",\r\n" + "            \"Toyata\"\r\n" + "     ],\r\n"
                + "     \"job\": \"Doctor\"\r\n" + "    }\r\n" + "]";

        ObjectMapper mapper = new ObjectMapper();

        MyPojo jsonObj[] = mapper.readValue(jsonStr, MyPojo[].class);

        for (MyPojo itr : jsonObj) {

            System.out.println("Val of getName is: " + itr.getName());
            System.out.println("Val of getCity is: " + itr.getCity());
            System.out.println("Val of getJob is: " + itr.getJob());
            System.out.println("Val of getCars is: " + itr.getCars() + "\n");

        }

POJO:

public class MyPojo {

private List<String> cars = new ArrayList<String>();

private String name;

private String job;

private String city;

public List<String> getCars() {
    return cars;
}

public void setCars(List<String> cars) {
    this.cars = cars;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getJob() {
    return job;
}

public void setJob(String job) {
    this.job = job;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
} }

  RESULT:-
         Val of getName is: John
         Val of getCity is: Berlin
         Val of getJob is: Teacher
         Val of getCars is: [FIAT, Toyata]

          Val of getName is: Mark
          Val of getCity is: Oslo
          Val of getJob is: Doctor
          Val of getCars is: [VW, Toyata]

One way around this problem is to use stored procedures with an output parameter.

exec sp_mysprocname @returnvalue output, @firstparam = 1, @secondparam=2

values you do not pass in default to the defaults set in the stored procedure itself. And you can get the results from your output variable.

Without a real example, it is difficult to make a recommendation. However, I've never needed to use that many WHERE clauses in a query and it may indicate a problem with the structure of your data.

I found possible answer. You have core-js version 3.0, and this version doesn't have separate folders for ES6 and ES7; that's why the application cannot find correct paths.

To resolve this error, you can downgrade the core-js version to 2.5.7. This version produces correct catalogs structure, with separate ES6 and ES7 folders.

To downgrade the version, simply run:

npm i -S [email protected]

In my case, with Angular, this works ok.

Just piling on... similar to Feiyu Zhou's post. Here I'm adding the machine name.

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
          .ConfigureAppConfiguration((context, builder) =>
          {
            var env = context.HostingEnvironment;
            var hostname = Environment.MachineName;
            builder.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
              .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true)
              .AddJsonFile($"appsettings.{hostname}.json", optional: true, reloadOnChange: true);
            builder.AddEnvironmentVariables();
            if (args != null)
            {
              builder.AddCommandLine(args);
            }
          })
        .UseStartup<Startup>();
  }

It depends on what exactly you want to accomplish. Let's assume you have this structure:

If you want the space at the end to be bigger, but have the background fill the space (or the border around the space) use

padding-bottom

Of course, there are also the corresponding values for space on the top:

padding-top
margin-top

Some examples:

<p style="line-height: 30px; width: 300px; border: 1px solid black;">
     Space between single lines 
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
     Space between single lines
</p>
<p style="margin-bottom: 30px; width: 300px; border: 1px solid black;">
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
     Space at the bottom, outside of the border
</p>
<p style="padding-bottom: 30px; width: 300px; border: 1px solid black;">
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border
     Space at the bottom, inside of the border

Of course you should put your styles in a separate stylesheet, the inline code was just to show the effect.

here you have a little schematic demonstration of what which value affects:

                                   line-height
           content                 +

The shape attribute for numpy arrays returns the dimensions of the array. If Y has n rows and m columns, then Y.shape is (n,m). So Y.shape[0] is n.

In [46]: Y = np.arange(12).reshape(3,4)

In [47]: Y
Out[47]: 
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

In [48]: Y.shape
Out[48]: (3, 4)

In [49]: Y.shape[0]

If you are looking for solution without using Java String functionality (i.e. split, match, etc.) then the following should help:

List<String> splitString(String string) {
        List<String> list = new ArrayList<String>();
        String token = "";
        char curr;
        for (int e = 0; e < string.length() + 1; e++) {
            if (e == 0)
                curr = string.charAt(0);
            else {
                curr = string.charAt(--e);
            }

            if (isNumber(curr)) {
                while (e < string.length() && isNumber(string.charAt(e))) {
                    token += string.charAt(e++);
                }
                list.add(token);
                token = "";
            } else {
                while (e < string.length() && !isNumber(string.charAt(e))) {
                    token += string.charAt(e++);
                }
                list.add(token);
                token = "";
            }

        }

        return list;
    }

boolean isNumber(char c) {
        return c >= '0' && c <= '9';
    }

This solution will split numbers and 'words', where 'words' are strings that don't contain numbers. However, if you like to have only 'words' containing English letters then you can easily modify it by adding more conditions (like isNumber method call) depending on your requirements (for example you may wish to skip words that contain non English letters). Also note that the splitString method returns ArrayList which later can be converted to String array.

Element.clientWidth & Element.clientHeight return the height/width of that element's content in addition any applicable padding.

The jQuery implementation of these are: $(target).outerWidth() & $(target).outerHeight()

.clientWidth & .clientHeight are included in the CSSOM View Module specification which is currently in the working draft stage. While modern browsers have a consistent implementation of this specification, to insure consistent performance across legacy platforms, the jQuery implementation should still be used.

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,  
    two @RequestParam parameters, HttpServletRequest request) throws ParseException {

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

I can't get that constructor to work either. This however seems to work:

# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)

You can also pass an integer in the constructor to set an initial capacity.

What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?

Edit:

It seems that you can use the array constructor like this:

$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)

Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.

In Firefox you can disable all autocomplete on a form by using the autocomplete="off/on" attribute. Likewise individual items autocomplete can be set using the same attribute.

<form autocomplete="off" method=".." action="..">  
<input type="text" name="textboxname" autocomplete="off">

You can test this in Chrome as it should work.

The below options works for me:

-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.rmi.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname={host name}

and remember to open 9010 port in the server

sudo ufw allow 9010/udp
sudo ufw allow 9010/tcp
sudo ufw reload

Forgetting to make the test class public prevents the test methods inside to be discovered.

I had a default xUnit project and deleted the sample UnitTest1.cs, replacing it with a controller test class, with a couple of tests, but none were found.

Long story short, after updating xUnit, Test.Sdk, xUnit.runner packages and rebuilding the project, I encountered a build error:

Error xUnit1000 Test classes must be public

Thankfully, the updated version threw this exception to spare me some trouble.

Modifying the test class to be public fixed my issue.

According to my research there is no way to do this exactly the way you want. You can manually re-create the table and copy the data, or SSMS can (and will) do this for you (when you drag and drop a column to a different order, it does this). In fact it souldn't matter what order the columns are... As an alternative solution you can select the data you want in the order you desired. For example, instead of using asterisk (*) in select, specify the column names in some order... Lets say MyTable has col1, col2, col3, colNew columns.

Instead of:

SELECT * FROM MyTable

You can use:

SELECT col1, colNew, col2, col3 FROM MyTable

The below worked for me

• First copy the content say "1:00:15" in notepad
• Then select a new column where you need to copy the text from notepad.
• Then right click and select format cell option and in that select numbers tab and in that tab select the option "Text".
• Now copy the content from notepad and paste in this Excel column. it will be text but in format "1:00:15".

I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me

find . -name one.pdf -o -name two.txt -o -name anotherone.jpg

-o or -or is logical OR. See Finding Files on Gnu.org for more information.

I was running this on CygWin.

This will get you the difference between two DateTime objects in milliseconds:

DateTime d1 = new DateTime();
DateTime d2 = new DateTime();

long diffInMillis = d2.getMillis() - d1.getMillis();

If you want to set environment variables permanently in Git-Bash, you have two options:

1. Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.

2. Set up env variables in .bash_profile file.

.bash_profile is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOME Windows environment variable.

.bash_profile file uses the regular Bash syntax and commands

# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir

# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

Read more information about Bash configurations files.

Many of them don't add this, especially in AWS EC2 Instance, I had the same issue and tried different solutions. Solution: one of my database URL inside the code was missing this parameter 'authSource', adding this worked for me.

mongodb://myUserName:MyPassword@ElasticIP:27017/databaseName?authSource=admin

You could use prop as well. Check the following code below.

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").prop("readonly", false); 
     }
     else{ 
         $("#no_of_staff").prop("readonly", true); 
     }
   });
});

'vb.net
'Extended file stributes
'visual basic .net sample 

Dim sFile As Object
        Dim oShell = CreateObject("Shell.Application")
        Dim oDir = oShell.Namespace("c:\temp")

        For i = 0 To 34
            TextBox1.Text = TextBox1.Text & oDir.GetDetailsOf(oDir, i) & vbCrLf
            For Each sFile In oDir.Items
                TextBox1.Text = TextBox1.Text & oDir.GetDetailsOf(sFile, i) & vbCrLf
            Next
            TextBox1.Text = TextBox1.Text & vbCrLf
        Next

It´s a issue of rounding the result, the solution for me is the following.

divider.divide(dividend,RoundingMode.HALF_UP);

Nice...

In my case I was trying to test SSL in my Visual Studio environment using IIS 7.

This is what I ended up doing to get it to work:

• Under my site in the 'Bindings...' section on the right in IIS, I had to add the 'https' binding to port 443 and select "IIS Express Developement Certificate".

• Under my site in the 'Advanced Settings...' section on the right I had to change the 'Enabled Protocols' from "http" to "https".

• Under the 'SSL Settings' icon I selected 'Accept' for client certificates.

• Then I had to recycle the app pool.

• I also had to import the local host certificate into my personal store using mmc.exe.

My web.config file was already configured correctly, so after I got all the above sorted out, I was able to continue my testing.

Because of the condition in while, the loop might never break:

while (entry != null) {
  // If entry never becomes null here, loop will never break.
}

Instead of the null check there, you can try this:

ZipEntry entry = null;
while ((entry = zip.getNextEntry()) != null) {
  // Rest of your code
}

@ClasG has already suggested:

^(?=\S*[a-z])(?=\S*[A-Z])(?=\S*\d)(?=\S*[^\w\s])\S{8,}$

but it does not accept _(underscore) as a special character (eg. Aa12345_).

An improved one is:

^(?=\S*[a-z])(?=\S*[A-Z])(?=\S*\d)(?=\S*([^\w\s]|[_]))\S{8,}$

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

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

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

see this page Entity Framework and AsNoTracking

What AsNoTracking Does

Entity Framework exposes a number of performance tuning options to help you optimise the performance of your applications. One of these tuning options is .AsNoTracking(). This optimisation allows you to tell Entity Framework not to track the results of a query. This means that Entity Framework performs no additional processing or storage of the entities which are returned by the query. However, it also means that you can't update these entities without reattaching them to the tracking graph.

there are significant performance gains to be had by using AsNoTracking

var bs []byte
value, _ := strconv.ParseInt(string(bs), 10, 64)

See this question.

Since TypeScript is compiled to JavaScript, at runtime you are running JavaScript, so the same rules will apply.

Did you tried JQuery's scrollTo method? http://demos.flesler.com/jquery/scrollTo/

Or you can extend JQuery and add your custom mentod:

jQuery.fn.extend({
 scrollToMe: function () {
   var x = jQuery(this).offset().top - 100;
   jQuery('html,body').animate({scrollTop: x}, 400);
}});

Then you can call this method like:

$("#header").scrollToMe();

This not the best way to manage session in react you can use web tokens to encrypt your data that you want save,you can use various number of services available a popular one is JSON web tokens(JWT) with web-tokens you can logout after some time if there no action from the client And after creating the token you can store it in your local storage for ease of access.

jwt.sign({user}, 'secretkey', { expiresIn: '30s' }, (err, token) => {
    res.json({
      token
  });

user object in here is the user data which you want to keep in the session

localStorage.setItem('session',JSON.stringify(token));

Yes.

Map.Entry can be used as a Pair.

Unfortunately it does not help with Java 8 streams as the problem is that even though lambdas can take multiple arguments, the Java language only allows for returning a single value (object or primitive type). This implies that whenever you have a stream you end up with being passed a single object from the previous operation. This is a lack in the Java language, because if multiple return values was supported AND streams supported them we could have much nicer non-trivial tasks done by streams.

Until then, there is only little use.

EDIT 2018-02-12: While working on a project I wrote a helper class which helps handling the special case of having an identifier earlier in the stream you need at a later time but the stream part in between does not know about it. Until I get around to release it on its own it is available at IdValue.java with a unit test at IdValueTest.java

You might find it very useful to sample Redis keys and group them by type. Salvatore has written a tool called redis-sampler that issues about 10000 RANDOMKEY commands followed by a TYPE on retrieved keys. In a matter of seconds, or minutes, you should get a fairly accurate view of the distribution of key types.

I've written an extension (unfortunately not anywhere open-source because it's work related), that adds a bit of introspection of key names via regexs that give you an idea of what kinds of application keys (according to whatever naming structure you're using), are stored in Redis. Combined with the more general output of redis-sampler, this should give you an extremely good idea of what's going on.

It's right, you are showing an iframe with 100% height respect to its container: the body.

Try this:

<body>
  <div style="width:100%; height:30px; background-color:#cccccc;">Banner</div>
  <div style="width:100%; height:90%; background-color:transparent;">
    <iframe src="http: //www.google.com.tw" style="width:100%; height:100%;">
    </iframe> 
  </div>
</body>

Of course, change the height of the second div to the height you want.

Right click on your project > Open Module Setting > Select "Project" in "Project Setting" section

Change the Project SDK to latest(may be API 21) and Project language level to 7+

I am sure that you probably wanted the answer that @GSerg gave. There is also a worksheet function called rows that will give you the number of rows.

So, if you have a named data range called Data that has 7 rows, then =ROWS(Data) will show 7 in that cell.

see event.data

commentbtn.bind('click', { id: '12', name: 'Chuck Norris' }, function(event) {
    var data = event.data;
    alert(data.id);
    alert(data.name);
});

If your data is initialized before binding the event, then simply capture those variables in a closure.

// assuming id and name are defined in this scope
commentBtn.click(function() {
    alert(id), alert(name);
});

I use Url.Content and never have a problem.

<script src="<%= Url.Content ("~/Scripts/jquery-1.4.1.min.js") %>" type="text/javascript"></script>

you can use DateUtils class in org.apache.commons.lang3.time package

DateUtils.addMonths(new Date(),1);

What you're looking for is date --date='06/12/2012 07:21:22' +"%s". Keep in mind that this assumes you're using GNU coreutils, as both --date and the %s format string are GNU extensions. POSIX doesn't specify either of those, so there is no portable way of making such conversion even on POSIX compliant systems.

Consult the appropriate manual page for other versions of date.

Note: bash --date and -d option expects the date in US or ISO8601 format, i.e. mm/dd/yyyy or yyyy-mm-dd, not in UK, EU, or any other format.

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

Version 3.8 or newer:

To show line numbers in the current window, go to Options and click Show Line Numbers.

To show them automatically, go to Options > Configure IDLE > General and check the Show line numbers in new windows box.

Version 3.7 or older:

Unfortunately there is not an option to display line numbers in IDLE although there is an enhancement request open for this.

However, there are a couple of ways to work around this:

1. Under the edit menu there is a go to line option (there is a default shortcut of Alt+G for this).

2. There is a display at the bottom right which tells you your current line number / position on the line:

You can use the following regex to get integer and floating values from a string:

re.findall(r'[\d\.\d]+', 'hello -34 42 +34.478m 88 cricket -44.3')

['34', '42', '34.478', '88', '44.3']

The other answers are all good. For Xilinx FPGA designs, it is best not to use global reset lines, and use initial blocks for reset conditions for most logic. Here is the white paper from Ken Chapman (Xilinx FPGA guru)

This can also happen if you by accident capitalize the parameter name, and call it the same as the object.
