I m invoking the weighted average through reflection. And had used method with more than one parameter.

Class cls = Class.forName(propFile.getProperty(formulaTyp));// reading class name from file

Object weightedobj = cls.newInstance(); // invoke empty constructor

Class<?>[] paramTypes = { String.class, BigDecimal[].class, BigDecimal[].class }; // 3 parameter having first is method name and other two are values and their weight
Method printDogMethod = weightedobj.getClass().getMethod("applyFormula", paramTypes); // created the object 
return BigDecimal.valueOf((Double) printDogMethod.invoke(weightedobj, formulaTyp, decimalnumber, weight)); calling the method

This code extracts the YouTube video duration using the YouTube API v3 by passing a video ID. It worked for me.

<?php
    function getDuration($videoID){
       $apikey = "YOUR-Youtube-API-KEY"; // Like this AIcvSyBsLA8znZn-i-aPLWFrsPOlWMkEyVaXAcv
       $dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$videoID&key=$apikey");
       $VidDuration =json_decode($dur, true);
       foreach ($VidDuration['items'] as $vidTime)
       {
           $VidDuration= $vidTime['contentDetails']['duration'];
       }
       preg_match_all('/(\d+)/',$VidDuration,$parts);
       return $parts[0][0] . ":" .
              $parts[0][1] . ":".
              $parts[0][2]; // Return 1:11:46 (i.e.) HH:MM:SS
    }

    echo getDuration("zyeubYQxHyY"); // Video ID
?>

For Xcode 11, React Native development environment. I usually have this problem when a dependency is not updated.

You can try following these steps, this usually works for me:

1- Delete your Podfile.lock (I like to use the command '-rm -rf Podfile.lock' on the terminal for this)

2- Delete your Pods folder (I like to use the command '-rm -rf Pods' in the terminal for this)

3- Delete your .xcworkspace

4- Pod install

5- Clear your project into XCode> Product> Clean Build Folder

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

Using the link from Daniel, I made an extension to make it more usable:

//UITableViewController+Ext.m
- (void)hideEmptySeparators
{
    UIView *v = [[UIView alloc] initWithFrame:CGRectZero];
    v.backgroundColor = [UIColor clearColor];
    [self.tableView setTableFooterView:v];
    [v release];
}

After some testings, I found out that the size can be 0 and it works as well. So it doesn't add some kind of margin at the end of the table. So thanks wkw for this hack. I decided to post that here since I don't like redirect.

I had the same problem.

I was trying to install dlib on my machine and it gave me this error. The tutorial mentioned in the question leads to downloading visual studio 2017. I solved this by uninstalling VS 2017 and installing VS 2015

One can install VS 2015 via this stackoverflow thread : How to download Visual Studio Community Edition 2015 (not 2017)

another example, split on non alpha-numeric and keep the separators

import re
a = "foo,bar@candy*ice%cream"
re.split('([^a-zA-Z0-9])',a)

output:

['foo', ',', 'bar', '@', 'candy', '*', 'ice', '%', 'cream']

explanation

re.split('([^a-zA-Z0-9])',a)

() <- keep the separators
[] <- match everything in between
^a-zA-Z0-9 <-except alphabets, upper/lower and numbers.

I had similar issue with Goland JetBrain and what worked for me is similar to what @user8382868 said but I only closed the IDE, renamed the folder .idea file to .idea.old and after re-opening the project everything worked.

First, use the bounding boxes as described by Jonathan Holland to find if you may have a collision.

From the (multi-color) sprites, create black and white versions. You probably already have these if your sprites are transparent (i.e. there are places which are inside the bounding box but you can still see the background). These are "masks".

Use Image.getRGB() on the mask to get at the pixels. For each pixel which isn't transparent, set a bit in an integer array (playerArray and enemyArray below). The size of the array is height if width <= 32 pixels, (width+31)/32*height otherwise. The code below is for width <= 32.

If you have a collision of the bounding boxes, do this:

// Find the first line where the two sprites might overlap
int linePlayer, lineEnemy;
if (player.y <= enemy.y) {
    linePlayer = enemy.y - player.y;
    lineEnemy = 0;
} else {
    linePlayer = 0;
    lineEnemy = player.y - enemy.y;
}
int line = Math.max(linePlayer, lineEnemy);

// Get the shift between the two
x = player.x - enemy.x;
int maxLines = Math.max(player.height, enemy.height);
for ( line < maxLines; line ++) {
    // if width > 32, then you need a second loop here
    long playerMask = playerArray[linePlayer];
    long enemyMask = enemyArray[lineEnemy];
    // Reproduce the shift between the two sprites
    if (x < 0) playerMask << (-x);
    else enemyMask << x;
    // If the two masks have common bits, binary AND will return != 0
    if ((playerMask & enemyMask) != 0) {
        // Contact!
    }

}

Unfortunately, the string.encode() method is not always reliable. Check out this thread for more information: What is the fool proof way to convert some string (utf-8 or else) to a simple ASCII string in python

Is something like this possible?

No. All you can do is detect the mouse going into the iframe, and potentially (though not reliably) when it comes back out (ie. trying to work out the difference between the pointer passing over the ad on its way somewhere else versus lingering on the ad).

I imagine a scenario where there is an invisible div on top of the iframe and the the div will just then pass the click event to the iframe.

Nope, there is no way to fake a click event.

By catching the mousedown you'd prevent the original click from getting to the iframe. If you could determine when the mouse button was about to be pressed you could try to get the invisible div out of the way so that the click would go through... but there is also no event that fires just before a mousedown.

You could try to guess, for example by looking to see if the pointer has come to rest, guessing a click might be about to come. But it's totally unreliable, and if you fail you've just lost yourself a click-through.

SOAP stands for Simple (sic) Object Access Protocol. It was intended to be a way to do Remote Procedure Calls to remote objects by sending XML over HTTP.

WSDL is Web Service Description Language. A request ending in '.wsdl' to an endpoint will result in an XML message describing request and response that a use can expect. It descibes the contract between service & client.

REST uses HTTP to send messages to services.

SOAP is a spec, REST is a style.

If you are using Rails 4.2 or greater you can use Rails enums.

Rails now has enums by default without the need for including any gems.

This is very similar (and more with features) to Java, C++ enums.

Quoted from http://edgeapi.rubyonrails.org/classes/ActiveRecord/Enum.html :

class Conversation < ActiveRecord::Base
  enum status: [ :active, :archived ]
end

# conversation.update! status: 0
conversation.active!
conversation.active? # => true
conversation.status  # => "active"

# conversation.update! status: 1
conversation.archived!
conversation.archived? # => true
conversation.status    # => "archived"

# conversation.update! status: 1
conversation.status = "archived"

# conversation.update! status: nil
conversation.status = nil
conversation.status.nil? # => true
conversation.status      # => nil

When merging two columns into a single datetime column, the accepted answer generates an error (pandas version 0.20.3), since the columns are sent to the date_parser function separately.

The following works:

def dateparse(d,t):
    dt = d + " " + t
    return pd.datetime.strptime(dt, '%d/%m/%Y %H:%M:%S')

df = pd.read_csv(infile, parse_dates={'datetime': ['date', 'time']}, date_parser=dateparse)

params.select{ |k,v| k =~ /choice\d/ }.map{ |k,v| v}.join("\t")

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

As a commenter mentioned you can get Values from net/url which has an Encode method. You could do something like this (req.URL.Query() returns the existing url.Values)

package main

import (
    "fmt"
    "log"
    "net/http"
    "os"
)

func main() {
    req, err := http.NewRequest("GET", "http://api.themoviedb.org/3/tv/popular", nil)
    if err != nil {
        log.Print(err)
        os.Exit(1)
    }

    q := req.URL.Query()
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")
    req.URL.RawQuery = q.Encode()

    fmt.Println(req.URL.String())
    // Output:
    // http://api.themoviedb.org/3/tv/popular?another_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

Postman is the best application to test your APIs !

You can import or export your routes and let him remember all your body requests ! :)

EDIT : This comment is 5 yea's old and deprecated :D

Here's the new Postman App : https://www.postman.com/

You want to use sections when you want a bit of code/content to render in a placeholder that has been defined in a layout page.

In the specific example you linked, he has defined the RenderSection in the _Layout.cshtml. Any view that uses that layout can define an @section of the same name as defined in Layout, and it will replace the RenderSection call in the layout.

Perhaps you're wondering how we know Index.cshtml uses that layout? This is due to a bit of MVC/Razor convention. If you look at the dialog where he is adding the view, the box "Use layout or master page" is checked, and just below that it says "Leave empty if it is set in a Razor _viewstart file". It isn't shown, but inside that _ViewStart.cshtml file is code like:

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

The way viewstarts work is that any cshtml file within the same directory or child directories will run the ViewStart before it runs itself.

Which is what tells us that Index.cshtml uses Shared/_Layout.cshtml.

X returns (value +3), while Y returns (value*2)

Given a value of 4, this means (4+3) * (4*2) = 7 * 8 = 56.

Although functions are not limited in scope (which means that you can safely 'nest' function definitions), this particular example is prone to errors:

1) You can't call y() before calling x(), because function y() won't actually be defined until x() has executed once.

2) Calling x() twice will cause PHP to redeclare function y(), leading to a fatal error:

Fatal error: Cannot redeclare y()

The solution to both would be to split the code, so that both functions are declared independent of each other:

function x ($y) 
{
  return($y+3);
}

function y ($z)
{
  return ($z*2);
}

This is also a lot more readable.

On linux : you can use ctrl + L or type command system clear.

This works in Swift 3.0:

btn.titleLabel?.font = UIFont(name:"Times New Roman", size: 20)

std::list doesn't provide any function to get element given an index. You may try to get it by writing some code, which I wouldn't recommend, because that would be inefficient if you frequently need to do so.

What you need is : std::vector. Use it as:

std::vector<Object> objects;
objects.push_back(myObject);

Object const & x = objects[0];    //index isn't checked
Object const & y = objects.at(0); //index is checked 

Sets became part of the core language in Python 2.4, in order to stay backwards compatible. I did this back then, which will work for you as well:

if sys.version_info < (2, 4):
    from sets import Set as set

If you are developing on Netbeans, you will not get the Third-Party add-ons. You can download the Skins directly from Samsung here: http://developer.samsung.com/android/tools-sdks

After download, unzip to ...\Android\android-sdk\add-ons[name of device]

Restart the Android SDK Manager, and the new device should be there under Extras.

It would be better to add the download site directly to the SDK...if anyone knows it, please post it.

Scott

the simple and easy way to do that is use on event:

$('body').on('click','#element',function(){
    //somthing
});

but we can say this is not the best way to do this. I suggest a another way to do this is use clone() method instead of using dynamic html. Write some html in you file for example:

<div id='div1'></div>

Now in the script tag make a clone of this div then all the properties of this div would follow with new element too. For Example:

var dynamicDiv = jQuery('#div1').clone(true);

Now use the element dynamicDiv wherever you want to add it or change its properties as you like. Now all jQuery functions will work with this element

Effectively, the IN statement creates a series of OR statements... so

SELECT * FROM table WHERE column IN (1, 2, 3)

Is effectively

SELECT * FROM table WHERE column = 1 OR column = 2 OR column = 3

And sadly, that is the route you'll have to take with your LIKE statements

SELECT * FROM table
WHERE column LIKE 'Text%' OR column LIKE 'Hello%' OR column LIKE 'That%'

I had the same issue when trying to update error message in UILabel in the same ViewController (it takes a little while to update data when trying to do that with normal coding). I used DispatchQueue in Swift 3 Xcode 8 and it works.

Google's R style guide simplifies the issue by prohibiting the "=" for assignment. Not a bad choice.

https://google.github.io/styleguide/Rguide.xml

The R manual goes into nice detail on all 5 assignment operators.

This code will fail for circular reference:

    JSON.stringify(circularReference);
// TypeError: cyclic object value

Use the below code:

 const getCircularReplacer = () => {
  const seen = new WeakSet();
  return (key, value) => {
    if (typeof value === "object" && value !== null) {
      if (seen.has(value)) {
        return;
      }
      seen.add(value);
    }
    return value;
  };
};

JSON.stringify(circularReference, getCircularReplacer());

This is the code:

        String date1 = "07/15/2013";
        String time1 = "11:00:01";
        String date2 = "07/16/2013";
        String time2 = "22:15:10";
        String format = "MM/dd/yyyy HH:mm:ss";
        SimpleDateFormat sdf = new SimpleDateFormat(format);
        Date fromDate = sdf.parse(date1 + " " + time1);
        Date toDate = sdf.parse(date2 + " " + time2);

        long diff = toDate.getTime() - fromDate.getTime();
        String dateFormat="duration: ";
        int diffDays = (int) (diff / (24 * 60 * 60 * 1000));
        if(diffDays>0){
            dateFormat+=diffDays+" day ";
        }
        diff -= diffDays * (24 * 60 * 60 * 1000);

        int diffhours = (int) (diff / (60 * 60 * 1000));
        if(diffhours>0){
            dateFormat+=diffhours+" hour ";
        }
        diff -= diffhours * (60 * 60 * 1000);

Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).

Here's the code relevant for your GUESTS Table.

1. Create AUDIT Table.

    IF NOT EXISTS
          (SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[Audit]') 
                   AND OBJECTPROPERTY(id, N'IsUserTable') = 1)
           CREATE TABLE Audit 
                   (Type CHAR(1), 
                   TableName VARCHAR(128), 
                   PK VARCHAR(1000), 
                   FieldName VARCHAR(128), 
                   OldValue VARCHAR(1000), 
                   NewValue VARCHAR(1000), 
                   UpdateDate datetime, 
                   UserName VARCHAR(128))
    GO

2. CREATE an UPDATE Trigger on the GUESTS Table as follows.

    CREATE TRIGGER TR_GUESTS_AUDIT ON GUESTS FOR UPDATE
    AS
    
    DECLARE @bit INT ,
           @field INT ,
           @maxfield INT ,
           @char INT ,
           @fieldname VARCHAR(128) ,
           @TableName VARCHAR(128) ,
           @PKCols VARCHAR(1000) ,
           @sql VARCHAR(2000), 
           @UpdateDate VARCHAR(21) ,
           @UserName VARCHAR(128) ,
           @Type CHAR(1) ,
           @PKSelect VARCHAR(1000)
           
    
    --You will need to change @TableName to match the table to be audited. 
    -- Here we made GUESTS for your example.
    SELECT @TableName = 'GUESTS'
    
    -- date and user
    SELECT         @UserName = SYSTEM_USER ,
           @UpdateDate = CONVERT (NVARCHAR(30),GETDATE(),126)
    
    -- Action
    IF EXISTS (SELECT * FROM inserted)
           IF EXISTS (SELECT * FROM deleted)
                   SELECT @Type = 'U'
           ELSE
                   SELECT @Type = 'I'
    ELSE
           SELECT @Type = 'D'
    
    -- get list of columns
    SELECT * INTO #ins FROM inserted
    SELECT * INTO #del FROM deleted
    
    -- Get primary key columns for full outer join
    SELECT @PKCols = COALESCE(@PKCols + ' and', ' on') 
                   + ' i.' + c.COLUMN_NAME + ' = d.' + c.COLUMN_NAME

I do just like below, after you set your column AsEnumarable you can sort, order or how you want.

 _dataTable.AsEnumerable().Select(p => p.Field<string>("ColumnName")).ToList();

I find this to be the superior solution, at least when dealing with web applications. The idea is this: convert the HTML page to a PDF document and send that to a printer via gsprint.

Even though gsprint is no longer in development, it works really, really well. You can choose the printer and the page orientation and size among several other options.

I convert the web page to PDF using Puppeteer, Chrome's headless browser. But you need to pass in the session cookie to maintain credentials.

With the new App Launcher YOUR APPS (not chrome extensions) stored in Users/[yourusername]/Applications/Chrome Apps/

EDITED: with the new release of the official Facebook app for Android (July 14 2011) IT WORKS!!!

OLD: The examples above do not work if the user chooses the Facebook app for sharing, but they do work if the user chooses the Seesmic app to post to Facebook. I guess Seesmic have a better implementation of the Facebook API than Facebook!

You have to have the branch checked out to pull, since pulling means merging into master, and you need a work tree to merge in.

git checkout master
git pull

No need to check out first; rebase does the right thing with two arguments

git rebase master test  

git checkout master
git merge test

git push by default pushes all branches that exist here and on the remote

git push
git checkout test

Use th:switch as an if-else

<span th:switch="${isThisTrue}">
  <i th:case="true" class="fas fa-check green-text"></i>
  <i th:case="false" class="fas fa-times red-text"></i>
</span>

Use th:switch as a switch

<span th:switch="${fruit}">
  <i th:case="Apple" class="fas fa-check red-text"></i>
  <i th:case="Orange" class="fas fa-times orange-text"></i>
  <i th:case="*" class="fas fa-times yellow-text"></i>
</span>

This will be sufficient to declare your enum variable and compare it:

enum Days {Saturday, Sunday, Tuesday, Wednesday, Thursday, Friday};
Days day = Saturday;
if (day == Saturday) {
    std::cout << "Ok its Saturday";
}

You can add this at the beginning after #include <iostream>:

using namespace std;

I would use pandas. The computationally heavy parts are written in cython or c-extensions to speed up the process and the syntax is very clean. For example, if you want to turn "Sheet1" from the file "your_workbook.xls" into the file "your_csv.csv", you just use the top-level function read_excel and the method to_csv from the DataFrame class as follows:

import pandas as pd
data_xls = pd.read_excel('your_workbook.xls', 'Sheet1', index_col=None)
data_xls.to_csv('your_csv.csv', encoding='utf-8')

Setting encoding='utf-8' alleviates the UnicodeEncodeError mentioned in other answers.

Add this to your project-level build.gradle file:

repositories {
    maven {
        url "https://maven.google.com"
    }
}

It worked for me

If you drill down through the abstractions of the IdentityDbContext you'll find that it looks just like your derived DbContext. The easiest route is Olav's answer, but if you want more control over what's getting created and a little less dependency on the Identity packages have a look at my question and answer here. There's a code example if you follow the link, but in summary you just add the required DbSets to your own DbContext subclass.

Setup JAVA_OPTS as a system variable with the following content:

JAVA_OPTS="-Xms256m -Xmx512m"

After that in a command prompt run the following commands:

SET JAVA_OPTS="-Xms256m -Xmx512m"

This can be explained as follows:

• allocate at minimum 256MBs of heap
• allocate at maximum 512MBs of heap

These values should be changed according to application requirements.

EDIT:

You can also try adding it through the Environment Properties menu which can be found at:

1. From the Desktop, right-click My Computer and click Properties.
2. Click Advanced System Settings link in the left column.
3. In the System Properties window click the Environment Variables button.
4. Click New to add a new variable name and value.
5. For variable name enter JAVA_OPTS for variable value enter -Xms256m -Xmx512m
6. Click ok and close the System Properties Tab.
7. Restart any java applications.

EDIT 2:

JAVA_OPTS is a system variable that stores various settings/configurations for your local Java Virtual Machine. By having JAVA_OPTS set as a system variable all applications running on top of the JVM will take their settings from this parameter.

To setup a system variable you have to complete the steps listed above from 1 to 4.

I lack the reputation to comment but ctime from Marlon Abeykoons response did not give the correct result for me. Using mtime does the trick though. (key=os.path.getmtime))

import glob
import os

list_of_files = glob.glob('/path/to/folder/*') # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getmtime)
print latest_file

I found two answers for that problem:

python os.path.getctime max does not return latest Difference between python - getmtime() and getctime() in unix system

Replace back-slash with forward-slash using one of the below:

• re.sub(r"\", "/", x)
• re.sub(r"\", "/", x)

There are two cases in which this error is raised.

1. You didn't declare the variable which is used
2. You didn't create the instances of the class

This is my most common use for The Fuck.

$ git push
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin master

$ fuck
git push --set-upstream origin master [enter/?/?/ctrl+c]
Counting objects: 9, done.
...

Also, it's fun to type swear words in your terminal.

Use double quote to enclose the quote or escape it.

newTemp = mystring.replace(/"/g, "'");

or

newTemp = mystring.replace(/"/g, '\'');

InnerHTML should be innerHTML:

document.getElementById('LblAboutMeCount').innerHTML = charsleft;

You should bind your checkLength function to your textarea with jQuery rather than calling it inline and rather intrusively:

$(document).ready(function() {
    $('textarea[name=text]').keypress(function(e) {
        checkLength($(this),512,$('#LblTextCount'));
    }).focus(function() {
        checkLength($(this),512,$('#LblTextCount'));
    });
});

You can neaten up checkLength by using more jQuery, and I wouldn't use 'object' as a formal parameter:

function checkLength(obj, maxlength, label) {
    charsleft = (maxlength - obj.val().length);
    // never allow to exceed the specified limit
    if( charsleft < 0 ) {
        obj.val(obj.val().substring(0, maxlength-1));
    }
    // I'm trying to set the value of charsleft into the label
    label.text(charsleft);
    $('#LblAboutMeCount').html(charsleft);
}

So if you apply the above, you can change your markup to:

<textarea name="text"></textarea>

While <strong> and <em> are of course more semantically correct, there seem definite legitimate reasons to use the <b> and <i> tags for customer-written content.

In such content, words or phrases may be bolded or italicized and it is generally not up to us to analyze the semantic reasoning for such bolding or italicizing.

Further, such content may refer to bolded and italicized words and phrases to convey a specific meaning.

An example would be an english exam question which instructs a student to replace the bolded word.

Then I prefer this:

map  <F12> :set hls!<CR>
imap <F12> <ESC>:set hls!<CR>a
vmap <F12> <ESC>:set hls!<CR>gv

And why? Because it toggles the switch: if highlight is on, then pressing F12 turns it off. And vica versa. HTH.

Try this:

private void NewNumber()
  {
     Random a = new Random(Guid.newGuid().GetHashCode());
     MyNumber = a.Next(0, 10);
  }

Some Explnations:

Guid : base on here : Represents a globally unique identifier (GUID)

Guid.newGuid() produces a unique identifier like "936DA01F-9ABD-4d9d-80C7-02AF85C822A8"

and it will be unique in all over the universe base on here

Hash code here produce a unique integer from our unique identifier

so Guid.newGuid().GetHashCode() gives us a unique number and the random class will produce real random numbers throw this

Sample: https://rextester.com/ODOXS63244

generated ten random numbers with this approach with result of:

-1541116401
7
-1936409663
3
-804754459
8
1403945863

1287118327

2112146189

1461188435
9
-752742620
4
-175247185
4
1666734552
7

we got two 1s next to each other, but the hash codes do not same.

If u want to use display=block it will make the content reader jump, so instead of using display you can set the left attribute to a negative value which does not exist in your html page to be displayed but actually it do.

I hope you must be understanding my point, if I am unable to make u understand u can message me back.

 @foreach (var m in Model)
    {

Nice detailed answer. just wanted to add one more thing which will definitely help others to see the UTF-8 encoding on URLs in action .

Follow the steps below to enable UTF-8 encoding on URLs in firefox.

1. type "about:config" in the address bar.

2. Use the filter input type to search for "network.standard-url.encode-query-utf8" property.

3. the above property will be false by default, turn that to TRUE.
4. restart the browser.

UTF-8 encoding on URLs works by default in IE6/7/8 and chrome.

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2
2        14         3
4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2
2        14         3
4        15         4

You can functionalize this however you like.

All the answers already covered most of the things but I will add my 5 cents. In short reverting a merge commit is quite simple:

git revert -m 1 <commit-hash>

If you have permission you can push it directly to the "master" branch otherwise simply push it to your "revert" branch and create pull request.

You might find more useful info on this subject here: https://itcodehub.blogspot.com/2019/06/how-to-revert-merge-in-git.html

ASP.NET Core & Bootstrap 4

Most up-to-date answer

I have re-worked @crush's neat solution for an updated, ASP.NET Core and Bootstrap 4 compatible way to solve this problem based on an IHtmlHelper extension method:

public static class LinkExtensions
{
    public static IHtmlContent ActiveActionLink(this IHtmlHelper html, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes)
    {
        return ActiveActionLink(html, linkText, actionName, controllerName, new RouteValueDictionary(routeValues), HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes));
    }

    public static IHtmlContent ActiveActionLink(this IHtmlHelper html, string linkText, string actionName, string controllerName, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes)
    {
        var routeData = html.ViewContext.RouteData;
        var routeAction = (string)routeData.Values["action"];
        var routeController = (string)routeData.Values["controller"];

        var active = controllerName.Equals(routeController) && actionName.Equals(routeAction);

        using (var writer = new StringWriter())
        {
            writer.WriteLine($"<li class='nav-item {(active ? "active" : "")}'>");
            html.ActionLink(linkText, actionName, controllerName, routeValues, htmlAttributes).WriteTo(writer, HtmlEncoder.Default);
            writer.WriteLine("</li>");
            return new HtmlString(writer.ToString());
        }
    }
}

Usage

<nav class="navbar">
    <div class="collapse navbar-collapse">
        <ul class="navbar-nav">
            @Html.ActiveActionLink("Home", "Index", "Home", null, new { @class = "nav-link" })
            @Html.ActiveActionLink("About", "About", "Home", null, new { @class = "nav-link" })
            @Html.ActiveActionLink("Contact", "Contact", "TimeTracking", null, new { @class = "nav-link" })
        </ul>
    </div>
</nav>

DateTime is a DataType which is used to store both Date and Time. But it provides Properties to get the Date Part.

You can get the Date part from Date Property.

http://msdn.microsoft.com/en-us/library/system.datetime.date.aspx

DateTime date1 = new DateTime(2008, 6, 1, 7, 47, 0);
Console.WriteLine(date1.ToString());

// Get date-only portion of date, without its time.
DateTime dateOnly = date1.Date;
// Display date using short date string.
Console.WriteLine(dateOnly.ToString("d"));
// Display date using 24-hour clock.
Console.WriteLine(dateOnly.ToString("g"));
Console.WriteLine(dateOnly.ToString("MM/dd/yyyy HH:mm"));   
// The example displays the following output to the console:
//       6/1/2008 7:47:00 AM
//       6/1/2008
//       6/1/2008 12:00 AM
//       06/01/2008 00:00

Here is what I'm doing:

git clone repo /tmp/folder
cp -rf /tmp/folder/.git /dest/folder/
cd /dest/folder
git checkout -f master

Add this script element to your body element:

<body>
  <script type="text/javascript">
     document.body.style.backgroundColor = "#AAAAAA";
  </script>
</body>

Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:

jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.

EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.

To blank it:

myObject["myVar"]=null;

To remove it:

delete myObject["myVar"]

as you can see in duplicate answers

For posterity, your question was how to send an http request to https://stackoverflow.com/questions. The real answer is: you cannot with telnet, cause this is an https-only reachable url.

So, you might want to use openssl instead of telnet, like this for instance

$ openssl s_client -connect stackoverflow.com:443
...
---
GET /questions HTTP/1.1
Host: stackoverflow.com

This will give you the https response.

Array indexes in JavaScript start at zero for the first item, so try this:

var firstArrayItem = myValues[0]

Of course, if you actually want the second item in the array at index 1, then it's myValues[1].

See Accessing array elements for more info.

git branch --unset-upstream stops tracking all the local branches, which is not desirable.

Remove the [branch "branch-name"] section from the .git/config file followed by

git branch -D 'branch-name' && git branch -D -r 'origin/branch-name'

works out the best for me.

Two options:

• Install Oracle client on the PC you want to run your program on

• Use Oracle.ManagedDataAccess.dll

You can get it on NuGet (search 'oracle managed') or download ODP.NET_Managed.zip (link is to a beta version, but points you in the right direction)

I use this so that the computers I deploy onto don't need Oracle client installed.

N.B. in my opinion this is good for console apps but annoying if you intend to install your application, so I install the client in that case.

Try below android studio plugin

Android WiFi ADB

HOW TO

1. Connect your device to your computer using a USB cable.
2. Then press the button on the toolbar and disconnect your USB once the plugin connects your device over WiFi.
3. You can now deploy, run and debug your device using your WiFi connection.

Github Link: https://github.com/pedrovgs/AndroidWiFiADB

NOTE: Remember that your device and your computer have to be in the same WiFi connection.

You cannot attach events before the elements you attach them to has loaded

This works -

Plain JS

DEMO

Recommended to use eventListener

// Should only be triggered on first page load
console.log('ho');

window.addEventListener("load", function() {
  document.getElementById('my-form').addEventListener("submit", function(e) {
    e.preventDefault(); // before the code
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
  })
});

<form id="my-form">
  <input type="text" name="in" value="some data" />
  <button type="submit">Go</button>
</form>

but if you do not need more than one listener you can use onload and onsubmit

// Should only be triggered on first page load
console.log('ho');

window.onload = function() {
  document.getElementById('my-form').onsubmit = function() {
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
    // You must return false to prevent the default form behavior
    return false;
  }
}

    <form id="my-form">
      <input type="text" name="in" value="some data" />
      <button type="submit">Go</button>
    </form>

jQuery

// Should only be triggered on first page load
console.log('ho');

$(function() {
  $('#my-form').on("submit", function(e) {
    e.preventDefault(); // cancel the actual submit

    /* do what you want with the form */

    // Should be triggered on form submit

    console.log('hi');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="my-form">
  <input type="text" name="in" value="some data" />
  <button type="submit">Go</button>
</form>

Here's a multiple-level sort method. I'm including a snippet from an Angular JS module, but you can accomplish the same thing by scoping the sort keys objects such that your sort function has access to them. You can see the full module at Plunker.

$scope.sortMyData = function (a, b)
{
  var retVal = 0, key;
  for (var i = 0; i < $scope.sortKeys.length; i++)
  {
    if (retVal !== 0)
    {
      break;
    }
    else
    {
      key = $scope.sortKeys[i];
      if ('asc' === key.direction)
      {
        retVal = (a[key.field] < b[key.field]) ? -1 : (a[key.field] > b[key.field]) ? 1 : 0;
      }
      else
      {
        retVal = (a[key.field] < b[key.field]) ? 1 : (a[key.field] > b[key.field]) ? -1 : 0;
      }
    }
  }
  return retVal;
};

I built one of the first SOAP servers, including code generation and WSDL generation, from the original spec as it was being developed, when I was working at Hewlett-Packard. I do NOT recommend using SOAP for anything.

The acronym "SOAP" is a lie. It is not Simple, it is not Object-oriented, it defines no Access rules. It is, arguably, a Protocol. It is Don Box's worst spec ever, and that's quite a feat, as he's the man who perpetrated "COM".

There is nothing useful in SOAP that can't be done with REST for transport, and JSON, XML, or even plain text for data representation. For transport security, you can use https. For authentication, basic auth. For sessions, there's cookies. The REST version will be simpler, clearer, run faster, and use less bandwidth.

XML-RPC clearly defines the request, response, and error protocols, and there are good libraries for most languages. However, XML is heavier than you need for many tasks.

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

Previous answers forgot to type the output as an Number again. There is several ways to do this, depending on your tastes.

+my_float.toFixed(2)

Number(my_float.toFixed(2))

parseFloat(my_float.toFixed(2))

You need to add the column with a default of null, then alter the column to have default now().

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP;
ALTER TABLE mytable ALTER COLUMN created_at SET DEFAULT now();

You didn't give us much to go on here, but I think you're just asking how to add content to the beginning or end of an element? If so here's how you can do it pretty easily:

//get the target div you want to append/prepend to
var someDiv = document.getElementById("targetDiv");

//append text
someDiv.innerHTML += "Add this text to the end";

//prepend text
someDiv.innerHTML = "Add this text to the beginning" + someDiv.innerHTML;

Pretty easy.

You can use arrows:

arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)

you can use cURL library for posting data: http://www.php.net/curl

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, "http://websiteURL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent."&password=".$password."&etc=etc");
$content=curl_exec($ch);

where postfield contains XML you need to send - you will need to name the postfield the API service (Clickatell I guess) expects

Use of pointer before character array

Normally, Character array is used to store single elements in it i.e 1 byte each

eg:

char a[]={'a','b','c'};

we can't store multiple value in it.

by using pointer before the character array we can store the multi dimensional array elements in the array

i.e.

char *a[]={"one","two","three"};
printf("%s\n%s\n%s",a[0],a[1],a[2]);

bootstrap had 15px top padding and 15px bottom padding on .navbar-nav > li > a so you need to decrease it by overriding it in your css file and .navbar has min-height:50px; decrease it as much you want.

for example

.navbar-nav > li > a {padding-top:5px !important; padding-bottom:5px !important;}
.navbar {min-height:32px !important}

add these classes to your css and then check.

It looks like your Spring component scan Base is missing UserServiceImpl

<context:component-scan base-package="org.assessme.com.controller." />

Only the default constructor can be called when creating objects in an array.

You can't pass an anonymous type to a non generic function, unless the parameter type is object.

public void LogEmployees (object obj)
{
    var list = obj as IEnumerable(); 
    if (list == null)
       return;

    foreach (var item in list)
    {

    }
}

Anonymous types are intended for short term usage within a method.

From MSDN - Anonymous Types:

You cannot declare a field, a property, an event, or the return type of a method as having an anonymous type. Similarly, you cannot declare a formal parameter of a method, property, constructor, or indexer as having an anonymous type. To pass an anonymous type, or a collection that contains anonymous types, as an argument to a method, you can declare the parameter as type object. However, doing this defeats the purpose of strong typing.

(emphasis mine)

Update

You can use generics to achieve what you want:

public void LogEmployees<T>(IEnumerable<T> list)
{
    foreach (T item in list)
    {

    }
}

The following solution worked for me the best. Since I'm relatively new to coding, I like to have visual confirmation that something is working the way I expect it to. I found it at the following site: http://htmlcheats.com/html/resize-the-html5-canvas-dyamically/

Here's the code:

<!DOCTYPE html>

<head>
    <meta charset="utf-8">
    <title>Resize HTML5 canvas dynamically | www.htmlcheats.com</title>
    <style>
    html, body {
      width: 100%;
      height: 100%;

      border: 0;
      overflow: hidden; /*  Disable scrollbars */

    <canvas id='c' style='position:absolute; left:0px; top:0px;'>

    <script>
    (function() {
        var
        // Obtain a reference to the canvas element using its id.
        htmlCanvas = document.getElementById('c'),
        // Obtain a graphics context on the canvas element for drawing.
        context = htmlCanvas.getContext('2d');

       // Start listening to resize events and draw canvas.
       initialize();

       function initialize() {
           // Register an event listener to call the resizeCanvas() function 
           // each time the window is resized.
           window.addEventListener('resize', resizeCanvas, false);
           // Draw canvas border for the first time.
           resizeCanvas();
        }

        // Display custom canvas. In this case it's a blue, 5 pixel 
        // border that resizes along with the browser window.
        function redraw() {
           context.strokeStyle = 'blue';
           context.lineWidth = '5';
           context.strokeRect(0, 0, window.innerWidth, window.innerHeight);
        }

        // Runs each time the DOM window resize event fires.
        // Resets the canvas dimensions to match window,
        // then draws the new borders accordingly.
        function resizeCanvas() {
            htmlCanvas.width = window.innerWidth;
            htmlCanvas.height = window.innerHeight;
            redraw();
        }
    })();

    </script>
</body> 
</html>

The blue border shows you the edge of the resizing canvas, and is always along the edge of the window, visible on all 4 sides, which was NOT the case for some of the other above answers. Hope it helps.

For ExpressJs router:

router.post('/login', async(req, res) => {
    return res.send({redirect: '/yoururl'});
})

Client-side:

    success: function (response) {
        if (response.redirect) {
            window.location = response.redirect
        }
    },

jdi has the right information concerning the use of GOPATH. I would add that if you intend to have a binary as well you might want to add one additional level to the directories.

~/projects/src/
    myproj/
        mypack/
            lib.go
            lib_test.go
            ...
        myapp/
            main.go

running go build myproj/mypack will build the mypack package along with it's dependencies running go build myproj/myapp will build the myapp binary along with it's dependencies which probably includes the mypack library.

I was not able to find the regex I was looking for so I modified a regex to fullfill my requirements, and apparently it seems to work fine now. My requirements were:

• Match URLs w/o protocol (www.gooogle.com)
• Match URLs with query parameters and path (http://subdomain.web-site.com/cgi-bin/perl.cgi?key1=value1&key2=value2e)
• Don't match URLs where there are not acceptable characters (e.g. "'£), for instance: (www.google.com/somthing"/somethingmore)

Here what I came up with, any suggestion is appreciated:

@Test
    public void testWebsiteUrl(){
        String regularExpression = "((http|ftp|https):\\/\\/)?[\\w\\-_]+(\\.[\\w\\-_]+)+([\\w\\-\\.,@?^=%&:/~\\+#]*[\\w\\-\\@?^=%&/~\\+#])?";

        assertTrue("www.google.com".matches(regularExpression));
        assertTrue("www.google.co.uk".matches(regularExpression));
        assertTrue("http://www.google.com".matches(regularExpression));
        assertTrue("http://www.google.co.uk".matches(regularExpression));
        assertTrue("https://www.google.com".matches(regularExpression));
        assertTrue("https://www.google.co.uk".matches(regularExpression));
        assertTrue("google.com".matches(regularExpression));
        assertTrue("google.co.uk".matches(regularExpression));
        assertTrue("google.mu".matches(regularExpression));
        assertTrue("mes.intnet.mu".matches(regularExpression));
        assertTrue("cse.uom.ac.mu".matches(regularExpression));

        assertTrue("http://www.google.com/path".matches(regularExpression));
        assertTrue("http://subdomain.web-site.com/cgi-bin/perl.cgi?key1=value1&key2=value2e".matches(regularExpression));
        assertTrue("http://www.google.com/?queryparam=123".matches(regularExpression));
        assertTrue("http://www.google.com/path?queryparam=123".matches(regularExpression));

        assertFalse("www..dr.google".matches(regularExpression));

        assertFalse("www:google.com".matches(regularExpression));

        assertFalse("https://[email protected]".matches(regularExpression));

        assertFalse("https://www.google.com\"".matches(regularExpression));
        assertFalse("https://www.google.com'".matches(regularExpression));

        assertFalse("http://www.google.com/path'".matches(regularExpression));
        assertFalse("http://subdomain.web-site.com/cgi-bin/perl.cgi?key1=value1&key2=value2e'".matches(regularExpression));
        assertFalse("http://www.google.com/?queryparam=123'".matches(regularExpression));
        assertFalse("http://www.google.com/path?queryparam=12'3".matches(regularExpression));

Michael Krelin's answer is close is not entirely safe, since it can be wrong in rare situations. The problem is that intervals in PostgreSQL do not have context with regards to things like daylight savings. Intervals store things internally as months, days, and seconds. Months aren't an issue in this case since subtracting two timestamps just use days and seconds but 'days' can be a problem.

If your subtraction involves daylight savings change-overs, a particular day might be considered 23 or 25 hours respectively. The interval will take that into account, which is useful for knowing the amount of days that passed in the symbolic sense but it would give an incorrect number of the actual hours that passed. Epoch on the interval will just multiply all days by 24 hours.

For example, if a full 'short' day passes and an additional hour of the next day, the interval will be recorded as one day and one hour. Which converted to epoch/3600 is 25 hours. But in reality 23 hours + 1 hour should be a total of 24 hours.

So the safer method is:

(EXTRACT(EPOCH FROM current_timestamp) - EXTRACT(EPOCH FROM somedate))/3600

As Michael mentioned in his follow-up comment, you'll also probably want to use floor() or round() to get the result as an integer value.

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

A couple ways this can be done:

This will make it a square

ul
{
  list-style-type: square;
}

This will make it green

li
{
  color: #0F0;
}

This will prevent the text from being green

li p
{
  color: #000;
}

However that will require that all text within lists be in paragraphs so that the color is not overridden.

A better way is to make an image of a green square and use:

ul
{
  list-style: url(green-square.png);
}

i think this might work for you

//<?php
    //checks file extension for images only
    $allowed =  array('gif','png' ,'jpg');
    $file = $_FILES['file']['name'];
    $ext = pathinfo($file, PATHINFO_EXTENSION);
        if(!in_array($ext,$allowed) ) 
            { 
//?>
<script>
       alert('file extension not allowed');
       window.location.href='some_link.php?file_type_not_allowed_error';
</script>

//<?php
exit(0);
    }
//?>

querySelector can be a complete CSS(3)-Selector with IDs and Classes and Pseudo-Classes together like this:

'#id.class:pseudo'

// or

'tag #id .class .class.class'

with getElementsByClassName you can just define a class

'class'

with getElementById you can just define an id

'id'

Program prints ab, goes back one character and prints si overwriting the b resulting asi. Carriage return returns the caret to the first column of the current line. That means the ha will be printed over as and the result is hai

I tried using this example but it failed miserably. Every time I use to invoke finish()/ finishactivity() inside a handler, I end up with this menacing java.lang.IllegalAccess Exception. i'm not sure how did it work for the one who posed the question.

Instead the solution I found was that create a method in your activity such as

void kill_activity()
{ 
    finish();
}

Invoke this method from inside the run method of the handler. This worked like a charm for me. Hope this helps anyone struggling with "how to close an activity from a different thread?".

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

You can use ServiceLocatorFactoryBean. First you need to create an interface for your class

public interface YourClassFactory {
    YourClass getClassByName(String name);
}

Then you have to create a config file for ServiceLocatorBean

@Configuration
@Component
public class ServiceLocatorFactoryBeanConfig {

    @Bean
    public ServiceLocatorFactoryBean serviceLocatorBean(){
        ServiceLocatorFactoryBean bean = new ServiceLocatorFactoryBean();
        bean.setServiceLocatorInterface(YourClassFactory.class);
        return bean;
    }
}

Now you can find your class by name like that

@Autowired
private YourClassfactory factory;

YourClass getYourClass(String name){
    return factory.getClassByName(name);
}

Please check if you have some config files in ${MAVEN_HOME}/conf directory like settings.xml. Those files overrides settings from .m2 folder and because of that, repository folder from .m2 might not be visible or discarded.

It is technically possible to put a caption on an ImageButton if you really want to do it. Just put a TextView over the ImageButton using FrameLayout. Just remember to not make the Textview clickable.

Example:

<FrameLayout>
    <ImageButton
        android:id="@+id/button_x"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@null"
        android:scaleType="fitXY"
        android:src="@drawable/button_graphic" >
    </ImageButton>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:clickable="false"
        android:text="TEST TEST" >
    </TextView>
</FrameLayout>

You'll need to decide how you'd like to handle exceptions thrown by the encrypt method.

Currently, encrypt is declared with throws Exception - however, in the body of the method, exceptions are caught in a try/catch block. I recommend you either:

• remove the throws Exception clause from encrypt and handle exceptions internally (consider writing a log message at the very least); or,
• remove the try/catch block from the body of encrypt, and surround the call to encrypt with a try/catch instead (i.e. in actionPerformed).

Regarding the compilation error you refer to: if an exception was thrown in the try block of encrypt, nothing gets returned after the catch block finishes. You could address this by initially declaring the return value as null:

public static byte[] encrypt(String toEncrypt) throws Exception{
  byte[] encrypted = null;
  try {
    // ...
    encrypted = ...
  }
  catch(Exception e){
    // ...
  }
  return encrypted;
}

However, if you can correct the bigger issue (the exception-handling strategy), this problem will take care of itself - particularly if you choose the second option I've suggested.

There are two ways to do it: creating filter condition 1) Manually 2) Dynamically.

Sample DataFrame:

val df = spark.createDataFrame(Seq(
  (0, "a1", "b1", "c1", "d1"),
  (1, "a2", "b2", "c2", "d2"),
  (2, "a3", "b3", null, "d3"),
  (3, "a4", null, "c4", "d4"),
  (4, null, "b5", "c5", "d5")
)).toDF("id", "col1", "col2", "col3", "col4")

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
|  3|  a4|null|  c4|  d4|
|  4|null|  b5|  c5|  d5|
+---+----+----+----+----+

1) Creating filter condition manually i.e. using DataFrame where or filter function

df.filter(col("col1").isNotNull && col("col2").isNotNull).show

or

df.where("col1 is not null and col2 is not null").show

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
+---+----+----+----+----+

2) Creating filter condition dynamically: This is useful when we don't want any column to have null value and there are large number of columns, which is mostly the case.

To create the filter condition manually in these cases will waste a lot of time. In below code we are including all columns dynamically using map and reduce function on DataFrame columns:

val filterCond = df.columns.map(x=>col(x).isNotNull).reduce(_ && _)

How filterCond looks:

filterCond: org.apache.spark.sql.Column = (((((id IS NOT NULL) AND (col1 IS NOT NULL)) AND (col2 IS NOT NULL)) AND (col3 IS NOT NULL)) AND (col4 IS NOT NULL))

Filtering:

val filteredDf = df.filter(filterCond)

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
+---+----+----+----+----+

A batch/WSH hybrid is able to call ShellExecute to display the UAC elevation dialog...

@if (1==1) @if(1==0) @ELSE
@echo off&SETLOCAL ENABLEEXTENSIONS
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"||(

@end @ELSE
ShA=new ActiveXObject("Shell.Application")
ShA.ShellExecute("cmd.exe","/c \""+WScript.ScriptFullName+"\"","","runas",5);
@end

Do I use one of these then cast to an Int?

Yes. There is no problem doing that. Decimals and doubles can represent integers exactly, so there will be no representation error. (You won't get a case, for instance, where Round returns 4.999... instead of 5.)

AdoptOpenJDK is a new website hosted by the java community. You can find .msi installers for OpenJDK 8 through 14 there, which will perform all the things listed in the question (Unpacking, registry keys, PATH variable updating (and JAVA_HOME), uninstaller...).

$str = str_replace(' ','',$str);

Or, replace with underscore, & nbsp; etc etc.

In MVC _Layout.cshtml:

<base href="@Request.GetBaseUrl()" />

Thats what we use!

public static class ExtensionMethods
{
public static string GetBaseUrl(this HttpRequestBase request)
        {
          if (request.Url == (Uri) null)
            return string.Empty;
          else
            return request.Url.Scheme + "://" + request.Url.Authority + VirtualPathUtility.ToAbsolute("~/");
        }
}

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Exactly as others told, shell script would help.

Just an additional case, IMHO it's worth mentioning (for someone else who stumble upon here, looking for an easier case), that is Environment replacement.

Environment variables (declared with the ENV statement) can also be used in certain instructions as variables to be interpreted by the Dockerfile.

The ${variable_name} syntax also supports a few of the standard bash modifiers as specified below:

• ${variable:-word} indicates that if variable is set then the result will be that value. If variable is not set then word will be the result.

• ${variable:+word} indicates that if variable is set then word will be the result, otherwise the result is the empty string.

This is not possible with CSS selectors. But you could use two classes instead of one, e.g. status and important instead of status-important.

In relation to the top answer I have a possible solution to the security risk.

<?php
     if(isset($_GET['path'])){
         if(in_array($_GET['path'], glob("*/*.*"))){
             header("Content-Type: application/octet-stream");
             header("Content-Disposition: attachment; filename=".$_GET['path']);
             readfile($_GET['path']);
         }
     }
?>

Using the glob() function (I tested the download file in a path one folder up from the file to be downloaded) I was able to make a quick array of files that are "allowed" to be downloaded and checked the passed path against it. Not only does this insure that the file being grabbed isn't something sensitive but also checks on the files existence at the same time.

~Note: Javascript / HTML~

HTML:

<iframe id="download" style="display:none"></iframe>

and

<input type="submit" value="Download" onclick="ChangeSource('document_path');return false;">

JavaScript:

<script type="text/javascript">
    <!--
        function ChangeSource(path){
            document.getElementByID('download').src = 'path_to_php?path=' + document_path;
        }
    -->
</script>

Take a look at GregorianCalendar, something like:

final Calendar now = GregorianCalendar.getInstance()
final int dayNumber = now.get(Calendar.DAY_OF_MONTH);

There is a free GUI Tool ServiceSecurityEditor

Which allows you to edit Windows Service permissions. I have successfully used it to give a non-Administrator user the rights to start and stop a service.

I had used "sc sdset" before I knew about this tool.

ServiceSecurityEditor feels like cheating, it's that easy :)

this is command for composer update please try this...

package will generate Jar/war as per POM file. install will install generated jar file to the local repository for other dependencies if any.

install phase comes after package phase

T and TRUE are True, F and FALSE are False. T and F can be redefined, however, so you should only rely upon TRUE and FALSE. If you compare 0 to FALSE and 1 to TRUE, you will find that they are equal as well, so you might consider them to be True and False as well.

You need to delimit each parameter name with a ":" at the very least. Technically the name is optional, but it is recommended for readability. So you could write:

- (NSMutableArray*)getBusStops:(NSString*)busStop :(NSSTimeInterval*)timeInterval;

or what you suggested:

- (NSMutableArray*)getBusStops:(NSString*)busStop forTime:(NSSTimeInterval*)timeInterval;

python: read lines from compressed text files

Using gzip.GzipFile:

HTTP 1.1 is the latest version of Hypertext Transfer Protocol, the World Wide Web application protocol that runs on top of the Internet's TCP/IP suite of protocols. compare to HTTP 1.0 , HTTP 1.1 provides faster delivery of Web pages than the original HTTP and reduces Web traffic.

Web traffic Example: For example, if you are accessing a server. At the same time so many users are accessing the server for the data, Then there is a chance for hanging the Server. This is Web traffic.

You are missing the else portion. If all the conditions are false then else will work where you haven't declared and returned anything from else branch.

private bool CheckALl()
{
  if(condition)
  {
    return true
  }
  else
  {
    return false
  }
}

Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML. Adding a value of selected to the item we want to appear as a header forces it to show in the first place as a placeholder. Something like:

<option selected disabled>Choose here</option>

The complete markup should be along these lines:

<select>
    <option selected disabled>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

You can take a look at this fiddle, and here's the result:

If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden attribute like so:

<select>
    <option selected disabled hidden>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

Check the fiddle here and the screenshot below.

Here is the solution:

<select>
    <option style="display:none;" selected>Select language</option>
    <option>Option 1</option>
    <option>Option 2</option>
</select>

Two options:

<button>multiline<br/>button<br/>text</button>

or

 <input type="button" value="Carriage&#13;&#10;return&#13;&#10;separators" style="text-align:center;">

myDataTable.AsEnumerable().Take(5).CopyToDataTable()

In my case, it was that the function was AMBIGUOUS as it was defined in the VBA library (present in my references), and also in the Microsoft Office Object Library (also present). I removed the Microsoft Office Object Library, and voila! No need to use the VBA. prefix.

If is ok for you to index the array you can do this:

<form>
    <input type="text" class="form-control" placeholder="Titel" name="levels[0][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[0][build_time]">

    <input type="text" class="form-control" placeholder="Titel" name="levels[1][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[1][build_time]">

    <input type="text" class="form-control" placeholder="Titel" name="levels[2][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[2][build_time]">
</form>

... to achieve that:

[levels] => Array ( 
  [0] => Array ( 
    [level] => 1 
    [build_time] => 2 
  ) 
  [1] => Array ( 
    [level] => 234 
   [build_time] => 456 
  )
  [2] => Array ( 
    [level] => 111
    [build_time] => 222 
  )
) 

But if you remove one pair of inputs (dynamically, I suppose) from the middle of the form then you'll get holes in your array, unless you update the input names...

$("#select_id").find("option:selected").text();

It is helpful if your control is on Server side. In .NET it looks like:

$('#<%= dropdownID.ClientID %>').find("option:selected").text();

If you need the transition to run infinitely, try the below example:

Back-button text is taken from parent view-controller's navigation item title. So whatever you set on previous view-controller's navigation item title, will be shown on current view controller's back button text. You can just put "" as navigation item title in parent view-controller's viewWillAppear method.

self.navigationItem.title = ""

Another way is to put

self.navigationController?.navigationBar.topItem?.title = ""

in current view controller's viewWillAppear method. This one will cause some other problem if navigation stack is too nested.

I'm not a Java developer so unfortunatly I can't comment on your code directly however I found this in an Oracle FAQ regarding the form of a connection string

jdbc:oracle:<drivertype>:<username/password>@<database>

From the Oracle JDBC FAQ

http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-faq-090281.html#05_03

Hope that helps

This is probably because an empty line at the end of your input file.

Try this:

for x in f:
    try:
        print int(x.strip(),16)
    except ValueError:
        print "Invalid input:", x

This can happen if you are using a case-sensitive file system on Windows. You can tell if this is the case if there is both a lib directory and a Lib directory in your venv directory :

> dir

Directory: C:\git\case\sensitive\filesystem\here\venv

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----        4/07/2018   4:10 PM                Include
d-----       22/01/2019   7:52 AM                Lib
d-----       22/01/2019   7:52 AM                lib
d-----       22/01/2019   7:52 AM                Scripts
d-----       22/01/2019   7:52 AM                tcl

To workaround this (until virtualenv.py gets fixed: https://github.com/pypa/virtualenv/issues/935) merge the two lib directories and make venv case-insensitive:

cd venv
move Lib rmthis
move .\rmthis\site-packages\ lib
rmdir rmthis
fsutil.exe file setCaseSensitiveInfo . disable

I tried all the solutions, none worked for me (using Swift 4), this is the solution that worked for me, if anyone in future faces the same problem.

let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options: 
 .ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)

yourImage.image = decodedimage

As for the meaning of each character described in C Primer Plus, what you expected is an 'correct' answer. It should be true for some computer architectures and compilers, but unfortunately not yours.

I wrote a simple c program to repeat your test, and got that 'correct' answer. I was using Mac OS and gcc.

Also, I am very curious what is the compiler that you were using. :)

Yii way

\yii\helpers\StringHelper::basename(get_class($model));

Yii uses this method in its Gii code generator

Method documentation

This method is similar to the php function basename() except that it will treat both \ and / as directory separators, independent of the operating system. This method was mainly created to work on php namespaces. When working with real file paths, php's basename() should work fine for you. Note: this method is not aware of the actual filesystem, or path components such as "..".

More information:

https://github.com/yiisoft/yii2/blob/master/framework/helpers/BaseStringHelper.php http://www.yiiframework.com/doc-2.0/yii-helpers-basestringhelper.html#basename()-detail

Depending on your problem slicing can be a really neat solution:

>>> b = (1, 2, 3, 4, 5)
>>> b[:2] + (8,9) + b[3:]
(1, 2, 8, 9, 4, 5)
>>> b[:2] + (8,) + b[3:]
(1, 2, 8, 4, 5)

This allows you to add multiple elements or also to replace a few elements (especially if they are "neighbours". In the above case casting to a list is probably more appropriate and readable (even though the slicing notation is much shorter).

I had this problem when creating a new table. It turns out the Foreign Key name I gave was already in use. Renaming the key fixed it.

Something like this for $.ajax (HTML5 only though):

$.ajax({
    xhr: function() {
        var xhr = new window.XMLHttpRequest();
        xhr.upload.addEventListener("progress", function(evt) {
            if (evt.lengthComputable) {
                var percentComplete = evt.loaded / evt.total;
                //Do something with upload progress here
            }
       }, false);

       xhr.addEventListener("progress", function(evt) {
           if (evt.lengthComputable) {
               var percentComplete = evt.loaded / evt.total;
               //Do something with download progress
           }
       }, false);

       return xhr;
    },
    type: 'POST',
    url: "/",
    data: {},
    success: function(data){
        //Do something on success
    }
});

my_file = open("first_file.txt", "r")
for line in my_file.readlines():
    if line[-1:] == "\n":
        print(line[:-1])
    else:
        print(line)
my_file.close() 

Return min and max value in tuple:

def side_values(num_list):
    results_list = sorted(num_list)
    return results_list[0], results_list[-1]


somelist = side_values([1,12,2,53,23,6,17])
print(somelist)

from MSDN for StringReader

    string textReaderText = "TextReader is the abstract base " +
        "class of StreamReader and StringReader, which read " +
        "characters from streams and strings, respectively.\n\n" +

        "Create an instance of TextReader to open a text file " +
        "for reading a specified range of characters, or to " +
        "create a reader based on an existing stream.\n\n" +

        "You can also use an instance of TextReader to read " +
        "text from a custom backing store using the same " +
        "APIs you would use for a string or a stream.\n\n";

    Console.WriteLine("Original text:\n\n{0}", textReaderText);

    // From textReaderText, create a continuous paragraph 
    // with two spaces between each sentence.
    string aLine, aParagraph = null;
    StringReader strReader = new StringReader(textReaderText);
    while(true)
    {
        aLine = strReader.ReadLine();
        if(aLine != null)
        {
            aParagraph = aParagraph + aLine + " ";
        }
        else
        {
            aParagraph = aParagraph + "\n";
            break;
        }
    }
    Console.WriteLine("Modified text:\n\n{0}", aParagraph);

To everyone who said that this is a bad idea I want to say it is not always a bad one. Sometimes it is very boring to have to zoom out to see all the content. For example when you type on an input on iOS it zooms to get it in the center of the screen. You have to zoom out after that cause closing the keyboard does not do the work. Also I agree that when you put many I hours in making a great layout and user experience you don't want it to be messed up by a zoom.

But the other argument is valuable as well for people with vision issues. However In my opinion if you have issues with your eyes you are already using the zooming features of the system so there is no need to disturb the content.

The answers were useful. After the change, I got duplicate logging of SQL statements, one in the log4j log file and one on the standard console. I changed the persistence.xml file to say show_sql to false to get rid of logging from the standard console. Keeping format_sql true also affects the log4j log file, so I kept that true.

you can delete the objects directly from the admin panel or else there is also an option to delete specific or selected id from an interactive shell by typing in python3 manage.py shell (python3 in Linux). If you want the user to delete the objects through the browser (with provided visual interface) e.g. of an employee whose ID is 6 from the database, we can achieve this with the following code, emp = employee.objects.get(id=6).delete()

THIS WILL DELETE THE EMPLOYEE WITH THE ID is 6.

If you wish to delete the all of the employees exist in the DB instead of get(), specify all() as follows: employee.objects.all().delete()

Lots of answers above! here is my take:

Sub kl()

    Dim wb As Workbook
    Dim ws As Worksheet

    Set ws = Sheets("name")
    Set wb = ThisWorkbook

With ws
    .Select
End With

End Sub

your first (perhaps accidental) mistake as we have all mentioned is "Sheet"... should be "Sheets"

The with block is useful because if you set wb to anything other than the current workbook, it will ececute properly

It is good that you've found your solution. But it is an interesting problem. I tried it out myself directly with sqlite3 (not going through rails) and did not get the same result, for me the order came out as expected.

What I suggest you to do if you want to continue digging in this problem is to start the sqlite3 command-line application and check the schema and the queries there:

This shows you the schema: .schema

And then just run the select statement as it showed up in the log files: SELECT * FROM "shows" ORDER BY date ASC, attending DESC

That way you see if:

1. The schema looks as you want it (that date is actually a date for instance)
2. That the date column actually contains a date, and not a timestamp (that is, that you don't have a time of the day that messes up the sort)

You have several techniques to do it.

This post - read the part about the revert will explain in details what we want to do and how to do it.

Here is the most simple solution to your problem:

# Checkout the desired branch
git checkout <branch>

# Undo the desired commit
git revert <commit>

# Update the remote with the undo of the code
git push origin <branch>

The revert command will create a new commit with the undo of the original commit.

An SQL JOIN clause is used to combine rows from two or more tables, based on a common field between them.

There are different types of joins available in SQL:

INNER JOIN: returns rows when there is a match in both tables.

LEFT JOIN: returns all rows from the left table, even if there are no matches in the right table.

RIGHT JOIN: returns all rows from the right table, even if there are no matches in the left table.

FULL JOIN: It combines the results of both left and right outer joins.

The joined table will contain all records from both the tables and fill in NULLs for missing matches on either side.

SELF JOIN: is used to join a table to itself as if the table were two tables, temporarily renaming at least one table in the SQL statement.

CARTESIAN JOIN: returns the Cartesian product of the sets of records from the two or more joined tables.

WE can take each first four joins in Details :

We have two tables with the following values.

TableA

id  firstName                  lastName
.......................................
1   arun                        prasanth                 
2   ann                         antony                   
3   sruthy                      abc                      
6   new                         abc                                           

TableB

id2 age Place
................
1   24  kerala
2   24  usa
3   25  ekm
5   24  chennai

....................................................................

INNER JOIN

Note :it gives the intersection of the two tables, i.e. rows they have common in TableA and TableB

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
 INNER JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
 INNER JOIN TableB
    ON TableA.id = TableB.id2;

Result Will Be

firstName       lastName       age  Place
..............................................
arun            prasanth        24  kerala
ann             antony          24  usa
sruthy          abc             25  ekm

LEFT JOIN

Note : will give all selected rows in TableA, plus any common selected rows in TableB.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
  LEFT JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
  LEFT JOIN TableB
    ON TableA.id = TableB.id2;

Result

firstName                   lastName                    age   Place
...............................................................................
arun                        prasanth                    24    kerala
ann                         antony                      24    usa
sruthy                      abc                         25    ekm
new                         abc                         NULL  NULL

RIGHT JOIN

Note : will give all selected rows in TableB, plus any common selected rows in TableA.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
 RIGHT JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
 RIGHT JOIN TableB
    ON TableA.id = TableB.id2;

Result

firstName                   lastName                    age     Place
...............................................................................
arun                        prasanth                    24     kerala

sruthy                      abc                         25     ekm
NULL                        NULL                        24     chennai

FULL JOIN

Note :It will return all selected values from both tables.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
  FULL JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
  FULL JOIN TableB
    ON TableA.id = TableB.id2;

Result

Interesting Fact

For INNER joins the order doesn't matter

For (LEFT, RIGHT or FULL) OUTER joins,the order matter

Better to go check this Link it will give you interesting details about join order

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

FOLLOWUP

To extract the contents from your email body, you can split it using SPLIT() and then parsing out the relevant information from it. See this example

Dim MyAr() As String

MyAr = Split(olMail.body, vbCrLf)

For i = LBound(MyAr) To UBound(MyAr)
    '~~> This will give you the contents of your email
    '~~> on separate lines
    Debug.Print MyAr(i)
Next i

Extra ( ) brackets may create problems in else if flow. This also creates Syntax error (missing operator) in query expression.

I wanted to update at the comment earlier made by DaShaun, but as it is my first time commenting, application didn't allow me.

Nonetheless, I am using eclipse and after I added the below mention code snippet to my pom.xml as suggested by Dashun and I ran the mvn clean package to generate the avro source files, but I was still getting compilation error in the workspace.

I right clicked on project_name -> maven -> update project and updated the project, which added the target/generated-sources as a source folder to my eclipse project.

Alert will block the program flow so you can just write the following.

echo ("<script LANGUAGE='JavaScript'>
    window.alert('Succesfully Updated');
    window.location.href='http://someplace.com';
    </script>");

You use a for..in loop for this. Be sure to check if the object owns the properties or all inherited properties are shown as well. An example is like this:

var obj = {a: 1, b: 2};
for (var key in obj) {
  if (obj.hasOwnProperty(key)) {
    var val = obj[key];
    console.log(val);
  }
}

Or if you need recursion to walk through all the properties:

var obj = {a: 1, b: 2, c: {a: 1, b: 2}};
function walk(obj) {
  for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
      var val = obj[key];
      console.log(val);
      walk(val);
    }
  }
}
walk(obj);

Image download with using image clicking!

I did this simple code!:)

<html>
<head>
<title> Download-Button </title>
</head>
<body>
<p> Click the image ! You can download! </p>
<a download="logo.png" href="http://localhost/folder/img/logo.png" title="Logo title">
<img alt="logo" src="http://localhost/folder/img/logo.png">

</body>
</html>

Use this function to check if a string is alphanumeric:

public boolean isAlphanumeric(String str)
{
    char[] charArray = str.toCharArray();
    for(char c:charArray)
    {
        if (!Character.isLetterOrDigit(c))
            return false;
    }
    return true;
}

It saves having to import external libraries and the code can easily be modified should you later wish to perform different validation checks on strings.

What Access File extension or you using? The Jet OLEDB or the Ace OLEDB. If your Access DB is .mdb (aka Jet Oledb)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.Oledb

namespace MembershipInformationSystem.Helpers
{
    public class dbs

    }
}

You can use it to raise errors as part of error-checking:

if (a < b):
    raise ValueError()

Or handle some errors, and then pass them on as part of error-handling:

try:
    f = open('file.txt', 'r')
except IOError:
    # do some processing here
    # and then pass the error on
    raise

split :: Eq a => a -> [a] -> [[a]]
split d [] = []
split d s = x : split d (drop 1 y) where (x,y) = span (/= d) s

E.g.

split ';' "a;bb;ccc;;d"
> ["a","bb","ccc","","d"]

A single trailing delimiter will be dropped:

split ';' "a;bb;ccc;;d;"
> ["a","bb","ccc","","d"]

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

You have to use the contents() method:

Maybe it's funny, but this works for me:

string.Join("",List1) != string.Join("", List2)

You can do it without a directive but i'm not sure it's the best way. To do this you must create array of array from the data you want to display in the table, and after that use 2 ng-repeat to iterate through the array.

to create the array for display use this function like that products.chunk(3)

Array.prototype.chunk = function(chunkSize) {
    var array=this;
    return [].concat.apply([],
        array.map(function(elem,i) {
            return i%chunkSize ? [] : [array.slice(i,i+chunkSize)];
        })
    );
}

and then do something like that using 2 ng-repeat

<div class="row" ng-repeat="row in products.chunk(3)">
  <div class="col-sm4" ng-repeat="item in row">
    {{item}}
  </div>
</div>

If you work with android.support.v7.widget.AppCompatSpinner here is the simplest tested solution using styles:

 <android.support.v7.widget.AppCompatSpinner
                    android:id="@+id/spefcialFx"
                    style="@style/Widget.AppCompat.Spinner.Underlined"
                    android:layout_width="200dp"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="4dp"
                    android:theme="@style/Spinner"
                    android:entries="@array/special_fx_arrays"
                    android:textSize="@dimen/text_size_normal"></android.support.v7.widget.AppCompatSpinner>

And the style:

<style name="Spinner" parent="Widget.AppCompat.Light.DropDownItem.Spinner">
        <item name="android:paddingStart">0dp</item>
        <item name="android:paddingEnd">0dp</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:backgroundTint">@color/red</item>
        <item name="android:textSize">14sp</item>
    </style>

The only downside is the android:backgroundTint sets color for both the dropdown arrow and the dropdown background.

I haven't tested this - but it should give you a general idea of the direction you need to take.

For this to work, I'm going to assume a few things about the text of the TextView:

1. The TextView consists of lines delimited with "\n".
2. The first line will not include an operator (+, -, * or /).
3. After the first line there can be a variable number of lines in the TextView which will all include one operator and one number.
4. An operator will allways be the first Char of a line.

First we get the text:

String input = tv1.getText().toString();

Then we split it up for each line:

String[] lines = input.split( "\n" );

Now we need to calculate the total value:

int total = Integer.parseInt( lines[0].trim() ); //We know this is a number.

for( int i = 1; i < lines.length(); i++ ) {
   total = calculate( lines[i].trim(), total );
}

The method calculate should look like this, assuming that we know the first Char of a line is the operator:

private int calculate( String input, int total ) {
   switch( input.charAt( 0 ) )
      case '+':
         return total + Integer.parseInt( input.substring( 1, input.length() );
      case '-':
         return total - Integer.parseInt( input.substring( 1, input.length() );             
      case '*':
         return total * Integer.parseInt( input.substring( 1, input.length() );             
      case '/':
         return total / Integer.parseInt( input.substring( 1, input.length() );
}

EDIT

So the above as stated in the comment below does "left-to-right" calculation, ignoring the normal order ( + and / before + and -).

The following does the calculation the right way:

String input = tv1.getText().toString();
input = input.replace( "\n", "" );
input = input.replace( " ", "" );
int total = getValue( input );

The method getValue is a recursive method and it should look like this:

private int getValue( String line ) {
  int value = 0;

  if( line.contains( "+" ) ) {
    String[] lines = line.split( "\\+" );
    value += getValue( lines[0] );

    for( int i = 1; i < lines.length; i++ )
      value += getValue( lines[i] );

    return value;
  }

  if( line.contains( "-" ) ) {
    String[] lines = line.split( "\\-" );
    value += getValue( lines[0] );

    for( int i = 1; i < lines.length; i++ )
      value -= getValue( lines[i] );

    return value;
  }

  if( line.contains( "*" ) ) {
    String[] lines = line.split( "\\*" );
    value += getValue( lines[0] );

    for( int i = 1; i < lines.length; i++ )
      value *= getValue( lines[i] );

    return value;
  }

  if( line.contains( "/" ) ) {
    String[] lines = line.split( "\\/" );
    value += getValue( lines[0] );

    for( int i = 1; i < lines.length; i++ )
      value /= getValue( lines[i] );

    return value;
  }

  return Integer.parseInt( line );
}

Special cases that the recursive method does not handle:

• If the first number is negative e.g. -3+5*8.
• Double operators e.g. 3*-6 or 5/-4.

Also the fact the we're using Integers might give some "odd" results in some cases as e.g. 5/3 = 1.

Use .val() not attr('value').

The component makers say that this has been fixed in the latest version of their component which we are using in-house, but this has been given to the customer yet.

Ask the component maker how to test whether the problem that the customer is getting is the problem which they say they've fixed in their latest version, without/before deploying their latest version to the customer.

You can write like below. Check out the syntax guidelines in this thread

AClass[] array;
...
array = new AClass[]{object1, object2};

If you find arrays annoying better use ArrayList.

contentType is the type of data you're sending, so application/json; charset=utf-8 is a common one, as is application/x-www-form-urlencoded; charset=UTF-8, which is the default.

dataType is what you're expecting back from the server: json, html, text, etc. jQuery will use this to figure out how to populate the success function's parameter.

If you're posting something like:

{"name":"John Doe"}

and expecting back:

{"success":true}

Then you should have:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "json",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        alert(result.success); // result is an object which is created from the returned JSON
    },
});

If you're expecting the following:

<div>SUCCESS!!!</div>

Then you should do:

var data = {"name":"John Doe"}
$.ajax({
    dataType : "html",
    contentType: "application/json; charset=utf-8",
    data : JSON.stringify(data),
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

One more - if you want to post:

name=John&age=34

Then don't stringify the data, and do:

var data = {"name":"John", "age": 34}
$.ajax({
    dataType : "html",
    contentType: "application/x-www-form-urlencoded; charset=UTF-8", // this is the default value, so it's optional
    data : data,
    success : function(result) {
        jQuery("#someContainer").html(result); // result is the HTML text
    },
});

It's an old thread, but I'll add some info for other people.

I experienced a similar issue with a program that writes PDF files, sometimes they take 30 seconds to render.. which is the same period that my watcher_FileCreated class waits before copying the file.

The files were not locked.

In this case I checked the size of the PDF and then waited 2 seconds before comparing the new size, if they were unequal the thread would sleep for 30 seconds and try again.

There are right answers but I just want to add one more option (requires downtime):

1. Stop Redis.
2. Delete RDB file (find location in redis.conf).
3. Start Redis.

Here is an example that reveals the logical problems that can occur when calling an overridable method in the super constructor.

class A {

    protected int minWeeklySalary;
    protected int maxWeeklySalary;

    protected static final int MIN = 1000;
    protected static final int MAX = 2000;

    public A() {
        setSalaryRange();
    }

    protected void setSalaryRange() {
        throw new RuntimeException("not implemented");
    }

    public void pr() {
        System.out.println("minWeeklySalary: " + minWeeklySalary);
        System.out.println("maxWeeklySalary: " + maxWeeklySalary);
    }
}

class B extends A {

    private int factor = 1;

    public B(int _factor) {
        this.factor = _factor;
    }

    @Override
    protected void setSalaryRange() {
        this.minWeeklySalary = MIN * this.factor;
        this.maxWeeklySalary = MAX * this.factor;
    }
}

public static void main(String[] args) {
    B b = new B(2);
    b.pr();
}

The result would actually be:

minWeeklySalary: 0

maxWeeklySalary: 0

This is because the constructor of class B first calls the constructor of class A, where the overridable method inside B gets executed. But inside the method we are using the instance variable factor which has not yet been initialized (because the constructor of A has not yet finished), thus factor is 0 and not 1 and definitely not 2 (the thing that the programmer might think it will be). Imagine how hard would be to track an error if the calculation logic was ten times more twisted.

I hope that would help someone.

Problem is that check weather you have closed all the streams or not if opened close the streams and delete,rename..etc the file this is worked for me

You need to set utf8mb4 in meta html and also in your server alter tabel and set collation to utf8mb4

I figured it this way:

* { padding: 0; margin: 0 }
body { height: 100%; white-space: nowrap }
html { height: 100% }

.red { background: red }
.blue { background: blue }
.yellow { background: yellow }

.header { width: 100%; height: 10%; position: fixed }
.wrapper { width: 1000%; height: 100%; background: green }
.page { width: 10%; height: 100%; float: left }

<div class="header red"></div>
<div class="wrapper">
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
</div>

I have the wrapper at 1000% and ten pages at 10% each. I set mine up to still have "pages" with each being 100% of the window (color coded). You can do eight pages with an 800% wrapper. I guess you can leave out the colors and have on continues page. I also set up a fixed header, but that's not necessary. Hope this helps.

The web site likely uses cookies to store your session information. When you run

curl --user user:pass https://xyz.com/a  #works ok
curl https://xyz.com/b #doesn't work

curl is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a in one browser session, and tried to access page b in a different one.

What you need to do is save the cookies created by the first command:

curl --user user:pass --cookie-jar ./somefile https://xyz.com/a

and then read them back in when running the second:

curl --cookie ./somefile https://xyz.com/b

Alternatively you can try downloading both files in the same command, which I think will use the same cookies.

uint32_t is standard, uint32 is not. That is, if you include <inttypes.h> or <stdint.h>, you will get a definition of uint32_t. uint32 is a typedef in some local code base, but you should not expect it to exist unless you define it yourself. And defining it yourself is a bad idea.

You only have to install the php5-curl library. You can do this by running

sudo apt-get install php5-curl

T-SQL doesn't have a FOR loop, it has a WHILE loop
WHILE (Transact-SQL)

WHILE Boolean_expression

Try:

EXEC sp_rename 'TableName.OldName', 'NewName', 'COLUMN'

Remember I'm using pip version 19.1 on python version 3.7.3

we can use express-session to send the required data

when you initialise the app

const express = require('express');
const app = express();
const session = require('express-session');
app.use(session({secret: 'mySecret', resave: false, saveUninitialized: false}));

so before redirection just save the context for the session

app.post('/category', function(req, res) {
    // add your context here 
req.session.context ='your context here' ;
    res.redirect('/');
});

Now you can get the context anywhere for the session. it can get just by req.session.context

app.get('/', function(req, res) {

    // So prepare the context
var context=req.session.context;
    res.render('home.jade', context);
});

"Failed to read artifact descriptor" problems generally indicate a problem with the dependency's pom file in the maven repository. I would suggest you to double check if the pom file's name is the same with the name maven expects, and also to check if the pom file contents are valid.

in Laravel 4 you can actually use an Event Listener for database queries.

Event::listen('illuminate.query', function($sql, $bindings)
{
    foreach ($bindings as $val) {
        $sql = preg_replace('/\?/', "'{$val}'", $sql, 1);
    }

    Log::info($sql);
});

Place this snippet anywhere, e.g. in start/global.php. It'll write the queries to the info log (storage/log/laravel.log).

To update Angular CLI to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
npm install --save-dev @angular/cli@latest
npm install

See the reference https://github.com/angular/angular-cli

For plaintext email using JavaScript, you may also use \r with encodeURIComponent().

For example, this message:

I was facing this same problem. Let me tell you how I solved it and achieved everything you all seem to be wanting.

Requirements:

1. Must have a button (or link) to a file - (or a generated memory stream)
2. Must click the button and have the file download

In my service, (I'm using Asp.net Web API), I have a controller returning an "HttpResponseMessage". I add a "StreamContent" to the response.Content field, set the headers to "application/octet-stream" and add the data as an attachment. I even give it a name "myAwesomeFile.xlsx"

response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(memStream);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "myAwesomeFile.xlsx" };

Now here's the trick ;)

I am storing the base URL in a text file that I read into a variable in an Angular Value called "apiRoot". I do this by declaring it and then setting it on the "run" function of the Module, like so:

app.value('apiRoot', { url: '' });
app.run(function ($http, apiRoot) {
    $http.get('/api.txt').success(function (data) {
        apiRoot.url = data;
    });
});

That way I can set the URL in a text file on the server and not worry about "blowing it away" in an upload. (You can always change it later for security reasons - but this takes the frustration out of development ;) )

And NOW the magic:

All I'm doing is creating a link with a URL that directly hits my service endpoint and target's a "_blank".

<a ng-href="{{vm.getFileHref(FileId)}}" target="_blank" class="btn btn-default">&nbsp;Excel File</a>

the secret sauce is the function that sets the href. You ready for this?

vm.getFileHref = function (Id) {
    return apiRoot.url + "/datafiles/excel/" + Id;
}

Yep, that's it. ;)

Even in a situation where you are iterating over many records that have files to download, you simply feed the Id to the function and the function generates the url to the service endpoint that delivers the file.

Hope this helps!

Use memory.limit(). You can increase the default using this command, memory.limit(size=2500), where the size is in MB. You need to be using 64-bit in order to take real advantage of this.

One other suggestion is to use memory efficient objects wherever possible: for instance, use a matrix instead of a data.frame.
